PROSPECTUS SUPPLEMENT SUMMARY

     This summary highlights important information about DTE Energy Company and this offering. It does not contain all the information that is important to you in connection with your decision to invest in the notes. We encourage you to read this prospectus supplement and the accompanying prospectus in their entirety as well as the information we incorporate by reference before making an investment decision.

DTE Energy Company

General

     We are an energy company. We are the parent holding company of The Detroit Edison Company, which we refer to as Detroit Edison, Michigan Consolidated Gas Company, which we refer to as MichCon, DTE Enterprises Inc., which we refer to as Enterprises (formerly MCN Energy Group Inc., which we refer to as MCN), and other subsidiaries engaged in energy-related businesses. DTE is an exempt holding company under the Public Utility Holding Company Act of 1935.

     We were the parent holding company for the International Transmission Company, which was sold in February 2003.

     Detroit Edison is a Michigan public utility engaged in the generation, purchase, distribution and sale of electric energy to 2.1 million customers in a 7,600 square-mile Southeastern Michigan service area. Detroit Edison’s service area includes about 13% of Michigan’s total land area and approximately five million people, which is about half of Michigan’s population. Detroit Edison’s residential customers reside in urban and rural areas, including an extensive shoreline along the Great Lakes and connecting waters.

     On May 31, 2001, we completed the acquisition of MCN (now Enterprises). Enterprises is a Michigan corporation primarily involved in natural gas production, gathering, processing, transmission, storage and distribution and energy marketing. Enterprises’ largest subsidiary, MichCon, is a natural gas utility serving 1.2 million customers in a 14,700-square-mile area in Michigan.

     We also have affiliates that engage in non-regulated business, including the following energy-related services and products:

•  synfuel projects;

•  the operation of pulverized coal facilities and coke oven batteries;

•  coal sourcing, blending and transportation;

•  landfill gas-to-energy facilities;

•  power marketing and trading;

•  providing expertise in the application of new energy technologies; and

•  real estate development.

RISK FACTORS

     An investment in the notes involves risks. You should carefully consider the following information, together with the other information in this prospectus supplement, the accompanying prospectus and the documents that are incorporated by reference in this prospectus supplement and the prospectus (including the “Risk Factors” set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2002), about risks concerning the notes, before buying any notes. See also “Cautionary Statements Regarding Forward-Looking Statements” in this prospectus supplement.

We may not be able to realize fully the cost savings and other benefits expected to be realized in connection with the acquisition of MCN, which may adversely affect our earnings and financial condition.

     The acquisition involves the integration of two large companies that previously operated independently of each other and the successful combination of the two business enterprises may take an extended period of time. Further, coordinating the operations involves a number of risks including:

•  Difficulties in combining operations and systems, including combining or coordinating utility operations;

•  Difficulties in retaining employees, customers and suppliers; and

•  The possibility that we will not achieve anticipated cost savings, or that any savings will be partially or fully offset by utility rate reductions or other actions and so will not benefit the holders of our securities.

     Inability to realize the full extent of, or any of, the anticipated benefits of the acquisition, as well as delays encountered in the transition process, could have a material adverse effect upon our revenues, level of expenses, operating results and financial condition.

We are a holding company and our ability to meet our debt obligations is dependent on the earnings of our subsidiaries and the distribution of such earnings to us in the form of dividends.

     We are a holding company and conduct our operations primarily through subsidiaries. Substantially all of our consolidated assets are held by such subsidiaries. Accordingly, our ability to meet our debt obligations, including our obligations on the notes, is largely dependent upon the earnings of these subsidiaries and the distribution or other payment of such earnings to us. The subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts due on our debt or to make any funds available for such payment. In addition, our subsidiaries’ ability to make dividend payments or other distributions to us may be restricted by their obligations to holders of their outstanding securities and to creditors, the availability of earnings and the needs of their businesses.

     The notes will be unsecured and unsubordinated obligations and will rank equally with all of our other unsecured and unsubordinated indebtedness from time to time outstanding, including amounts, if any, outstanding under our $700 million revolving credit agreement as well as our guarantees of non-regulated affiliate obligations. Because we are a holding company that conducts substantially all of our operations through our subsidiaries, the notes will be effectively subordinated to claims of creditors and preferred stockholders of those subsidiaries, including their trade creditors, debtholders, secured creditors, taxing authorities and guarantee holders, if any.

     At December 31, 2002, the total amount of DTE’s outstanding unsecured and unsubordinated indebtedness (excluding guarantees and short term borrowings), on an unconsolidated basis, was approximately $1.948 billion ($2.348 billion after giving effect to the issuance of the notes). At December 31, 2002, approximately $4.509 billion of outstanding indebtedness, consisting of indebtedness of our subsidiaries, would rank effectively senior to the notes. In addition, at such date, our subsidiaries had approximately $1.792 billion of non-recourse indebtedness, including securitization bonds issued in March 2001 for the benefit of Detroit Edison, appearing on our balance sheet. We and our subsidiaries may incur

S-8

additional indebtedness and other liabilities in the future. See “Description of Debt Securities — Ranking” in the accompanying prospectus.

Changes in regulatory environment and increased competition may result in decreased earnings.

     The MCN acquisition has combined two companies that to a large extent share a common regulatory environment and are affected by a number of similar factors, including deregulation and increased competition. Michigan is addressing competition in the electric and gas industry and the impact, if any, of the adoption and implementation of one or more regulatory orders and/or statutes is currently unknown. Furthermore, the utility industry has been undergoing dramatic structural change for several years, resulting in increasing competitive pressures faced by electric and natural gas utility companies. Increased competition may create greater risks to the stability of utility earnings generally and may in the future reduce our earnings from retail electric and natural gas sales. In a deregulated environment, formerly regulated utility companies that are not responsive to a competitive energy marketplace may suffer erosion in market share, revenues and profits as competitors gain access to their customers.

There is no existing market for the notes and we cannot assure that such a market will develop.

     There is no existing market for the notes and we do not intend to apply for listing of the notes on any securities exchange. We cannot assure that an active trading market for the notes will develop. There can be no assurances as to the liquidity of any market that may develop for the notes, the ability of noteholders to sell their notes or the price at which the noteholders will be able to sell their notes. Future trading prices of the notes will depend on many factors including, among other things, prevailing interest rates, our operating results and the market for similar securities.

USE OF PROCEEDS

     Total net proceeds from the sale of the notes, after expenses and underwriting discount, are expected to be approximately $393,152,000. In March 2003, Barclays Capital Inc. agreed to purchase the outstanding MCN Notes from the holder thereof for approximately $112,773,000 on April 1, 2003. We have agreed to exchange the MCN Notes for approximately $113,657,000 principal amount of the notes and to receive cash for the remaining notes. Following this offering, we will retire the MCN Notes. We expect to use the remaining proceeds to repay a portion of our 6.17% Remarketed Notes, Series A due 2038 maturing June 15, 2038 and our 7.11% Remarketed Notes, 1998 Series B maturing November 15, 2038 (each issued by DTE Capital Corporation), and for general corporate purposes.

RATIOS OF EARNINGS TO FIXED CHARGES

     Our ratios of earnings to fixed charges were as follows for the periods indicated in the table below:

	Year Ended December 31,
	2002		2001		2000		1999		1998
Ratio of earnings to fixed charges		2.06		1.52		2.37		2.48		2.72

     Our ratios of earnings to fixed charges were computed based on:

•  “earnings,” which consist of consolidated income plus income taxes and fixed charges, except capitalized interest; and

•  “fixed charges,” which consist of consolidated interest on indebtedness, including capitalized interest, amortization of debt discount and expense and the estimated portion of rental expense attributable to interest.

DESCRIPTION OF NOTES

     The following summary sets forth the specific terms and provisions of the notes. The following description of the specific terms of the notes supplements, and, to the extent inconsistent, replaces, the description of the general terms and provisions of the debt securities and the indenture governing the notes set forth in the accompanying prospectus under “Description of Debt Securities.” The following summary is qualified in its entirety by reference to the terms and provisions of the notes and the indenture, which are incorporated in this prospectus supplement and the accompanying prospectus by reference. Capitalized terms not otherwise defined in this section, or in the accompanying prospectus, have the meanings given to them in the notes and in the indenture.

General

     We will issue the notes as a series of our unsecured and unsubordinated debt securities under the indenture described in the accompanying prospectus.

     The indenture does not limit the amount of senior notes on other debt securities we may issue under it. As of December 31, 2002, approximately $1.948 billion aggregate principal amount of debt securities were issued and outstanding under the indenture.

     We may also issue additional notes having the same ranking and the same interest rate, maturity, CUSIP number and other terms as the notes, without the consent of the holders. Any such additional notes will, together with the other notes of that series, constitute a single series of debt securities under the indenture.

     The notes will be issued in the form of one or more fully-registered notes in global form deposited with, or on behalf of, The Depository Trust Company (“DTC”) and registered in the name of DTC’s, as depositary, nominee, Cede & Co. So long as DTC or its nominee is the registered owner of a global note, DTC or its nominee, as the case may be, will be considered the sole holder of the notes for all purposes under the indenture. The beneficial owners of the notes will be entitled only to those rights and benefits afforded to them in accordance with DTC’s regular operating procedures. Except in the limited circumstances described in the accompanying prospectus, owners of beneficial interests in the notes will not be entitled to have notes registered in their names, will not receive or be entitled to receive physical delivery of notes in certificated form and will not be considered the registered owners or holders of notes under the indenture. See “Book-Entry Securities” in the accompanying prospectus.

     The authorized denominations for the notes will be $1,000 and integrals thereof.

Maturity and Payment

     The notes will mature on April 15, 2033 and will bear interest from the date of issuance at the rate of 6 3/8% per year. Interest will be payable in U.S. dollars semi-annually in arrears on April 15 and October 15, commencing October 15, 2003. Interest punctually paid will be paid to the persons in whose names the notes are registered at the close of business on the 15th calendar day (whether or not a business day) before each interest payment date. “Business day” means any day other than a Saturday or Sunday or a day on which commercial banks in the State of New York are required or authorized by law or executive order to be closed. Interest on the notes will be computed on the basis of a 360-day year consisting of twelve 30-day months.

     If any interest payment date, redemption date or maturity date of a note falls on a day that is not a business day, the required payment of principal, premium, if any, and interest will be made on the next succeeding business day as if made on the date that the payment was due and no interest will accrue on that payment for the period from and after that interest payment date, redemption date or maturity date, as the case may be, to the date of payment on the next succeeding business day.

S-11

Redemption

     The notes may be redeemed at our option, in whole or in part, at any time at the redemption prices set forth herein. The redemption price will be equal to the greater of the following amounts:

•  100% of the principal amount of the notes being redeemed on the redemption date; or

•  the sum of the present values of the remaining scheduled payments of principal and interest on the notes being redeemed on that redemption date (not including any portion of any payments of interest accrued to the redemption date) discounted to the redemption date on a semiannual basis at the Adjusted Treasury Rate (as defined below) plus 20 basis points as determined by the Reference Treasury Dealer (as defined below);

plus, in each case, accrued and unpaid interest thereon to the redemption date. Notwithstanding the foregoing, installments of interest on notes 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 according to the notes and the indenture. The redemption price will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

     If notice has been given as provided in the indenture and funds for the redemption of any notes called for redemption have been made available on the redemption date, such notes will cease to bear interest on the date fixed for redemption. Thereafter, the only right of the holders of such notes will be to receive payment of the redemption price.

     Notice of any redemption will be given to holders at their addresses, as shown in the security register for such notes, not more than 60 nor less than 30 days prior to the date fixed for redemption. The notice of redemption will specify, among other items, the redemption price and the principal amount of the notes held by such holder to be redeemed.

     We will notify the trustee at least 60 days prior to giving notice of redemption (or such shorter period as is satisfactory to the trustee) of the aggregate principal amount of notes to be redeemed and their redemption date. If less than all of the notes of a series are to be redeemed, the trustee shall select which notes are to be redeemed in a manner it deems to be fair and appropriate.

     “Adjusted Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated on the third business day preceding the redemption date, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

     “Comparable Treasury Issue” means the United States Treasury security selected by the Reference Treasury Dealer as having a maturity comparable to the remaining term of the notes to be redeemed 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 to the remaining term of such notes.

     “Comparable Treasury Price” means, with respect to any redemption date, (A) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (B) if the trustee obtains fewer than three such Reference Treasury Dealer Quotations, the average of all such quotations, or (C) if only one Reference Treasury Dealer Quotation is received, such quotation.

     “Reference Treasury Dealer” means (A) 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 shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), we will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the trustee after consultation with us.

S-12

     “Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any 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 redemption date.

     The notes will not be entitled to the benefit of any sinking fund.

Limitation on Secured Debt

     The limitation on secured debt set forth in the indenture (see Section 1009) and described in the accompanying prospectus will be applicable to the notes. See “Description of Debt Securities — Covenants — Limitation on Secured Debt” in the accompanying prospectus.

Defeasance

     We may defease a series of the notes or certain covenants relating to a series of the notes as described under “Description of Debt Securities — Discharge, Defeasance and Covenant Defeasance” in the accompanying prospectus.

Concerning the Trustee

     In addition to acting as trustee under the indenture and in certain other capacities as described in the accompanying prospectus, The Bank of New York also acts as a lender and provides other banking services in the ordinary course of its business to DTE and its affiliates.

S-13

UNDERWRITING

     Under the terms and subject to the conditions contained in an underwriting agreement dated March 27, 2003, we have agreed to sell to the underwriters named below, for whom Barclays Capital Inc. and Salomon Smith Barney Inc. are acting as representatives, the following respective principal amounts of notes:

		Principal Amount
Underwriters		of Notes
Barclays Capital Inc.		$	155,000,000
Salomon Smith Barney Inc.			155,000,000
BNY Capital Markets, Inc.			30,000,000
Morgan Stanley & Co. Incorporated			30,000,000
Scotia Capital (USA) Inc.			30,000,000
	Total	$	400,000,000

     The underwriting agreement provides that the underwriters are obligated to purchase all of the notes if any are purchased. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may be increased or the offering of notes may be terminated.

     The underwriters propose to offer the notes initially at the public offering price on the cover page of this prospectus supplement and to selling group members at that price less a selling concession of .500% of the principal amount per note. The underwriters and selling group members may allow a discount of .250% of the principal amount per note on sales to other broker/dealers. After the initial public offering, the representatives may change the public offering price and concession and discount to broker/dealers.

     We estimate that our out of pocket expenses for this offering will be approximately $300,000.

     The notes are a new issue of securities with no established trading market. One or more of the underwriters intends to make a secondary market for the notes. However, they are not obligated to do so and may discontinue making a secondary market for the notes at any time without notice. No assurance can be given as to how liquid the trading market for the notes will be.

     In connection with the offering the underwriters, may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids in accordance with Regulation M under the Exchange Act.

•  Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.

•  Over-allotment involves sales by the underwriters of notes in excess of the principal amount of the notes the underwriters are obligated to purchase, which creates a syndicate short position.

•  Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover syndicate short positions. A short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the notes in the open market after pricing that could adversely affect investors who purchase in the offering.

•  Penalty bids permit the representatives to reclaim a selling concession from a syndicate member when the notes originally sold by the syndicate member are purchased in a stabilizing transaction or a syndicate covering transaction to cover syndicate short positions.

     These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of the notes or preventing or retarding a decline in the market price of the notes. As a result the price of the notes may be higher than the price that might otherwise exist in the open market. These transactions, if commenced, may be discontinued at any time.

S-14

     We have agreed to indemnify the underwriters against liabilities under the Securities Act or to contribute to payments which the underwriters may be required to make in that respect.

     A portion of the notes will be issued in exchange for the delivery by Barclays Capital Inc. to us of the MCN Notes, which were previously purchased by Barclays Capital Inc. from Morgan Stanley & Co. International Limited, an affiliate of Morgan Stanley & Co. Incorporated as described in “Use of Proceeds.” Because more than ten percent of the net proceeds of the offering may be paid to members or affiliates of members of the National Association of Securities Dealers, Inc. participating in the offering, the offering is being conducted in accordance with NASD Conduct Rule 2710(c)(8).

     The underwriters and their affiliates have acted as lenders, and performed certain investment banking and advisory and general financing, trustee and banking services for DTE and its affiliates from time to time for which they have received customary fees and expenses. The underwriters and their affiliates may, from time to time, engage in transactions with or perform services for DTE and its affiliates in the ordinary course of their business.

Cautionary Statements Regarding Forward-Looking Statements

      This prospectus and the documents incorporated by reference in this prospectus contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, with respect to the financial condition, results of operations and business of DTE Energy.

All forward-looking statements we make are expressly qualified in their entirety by the cautionary statements contained or referred to in this section.

     These forward-looking statements are subject to numerous assumptions, risks and uncertainties. Our actual results may differ from those expected as a result of a number of variables including, but not limited to,

•  interest rates;

•  the use of derivative instruments and their related accounting treatment;

•  access to the capital markets and capital market conditions;

•  the level of borrowings;

•  the effects of weather and other natural phenomena on operations;

•  actual sales;

•  the capital intensive nature of our business;

•  economic climate and growth in the geographic areas in which we, and our subsidiaries, do business;

•  the implementation of electric utility restructuring in Michigan (which involves pending regulatory and related judicial proceedings, and actual and possible reductions in authorized rates and earnings);

•  the effects of changes in governmental policies, including income taxes and environmental compliance and nuclear requirements and our ability to recover these costs through rate increases;

3

•  the impact of Federal Energy Regulatory Commission and Michigan Public Service Commission proceedings and regulations;

•  the contributions to earnings by our non-regulated business;

•  changes in the cost of natural gas; and

•  the effects of new accounting pronouncements.

     In addition, our acquisition of MCN Energy Group Inc., which we refer to as MCN, on May 31, 2001 and the timing of the accretive effect of this acquisition will affect our expected results.

     You are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date of this prospectus or the date of any document incorporated by reference. We undertake no obligation to release publicly any revisions to such forward-looking statements to reflect events or circumstances after the date of this document or to reflect the occurrence of unanticipated events.

DTE Energy Company

      DTE Energy Company, a Michigan corporation incorporated in 1935, is an exempt holding company under the Public Utility Holding Company Act of 1935. We are the parent holding company of The Detroit Edison Company, which we refer to as Detroit Edison, the International Transmission Company, which we refer to as ITC, DTE Enterprises Inc., which we refer to as Enterprises, and other subsidiaries engaged in energy trading, energy services and other energy-related businesses.

     Detroit Edison is a Michigan public utility engaged in the generation, purchase, distribution and sale of electric energy to 2.1 million customers in a 7,600 square mile area in Southeastern Michigan. Detroit Edison’s service area includes about 13% of Michigan’s total land area and approximately five million people, which is about half of Michigan’s population. Detroit Edison’s residential customers reside in urban and rural areas, including an extensive shoreline along the Great Lakes and connecting waters.

     On May 31, 2001, DTE Energy completed the acquisition of MCN. At that time MCN merged with Enterprises, with Enterprises being the surviving corporation. Enterprises, a Michigan corporation, is an exempt holding company under the Public Utility Holding Company Act of 1935. Enterprises is primarily involved in natural gas production, gathering, processing, transmission, storage, distribution and energy marketing. Enterprises’ largest subsidiary, Michigan Consolidated Gas Company, which we refer to as MichCon, is a natural gas utility serving 1.2 million customers in a 14,700 square mile area in Michigan.

     We also have affiliates that engage in non-regulated businesses, including the following energy-related services and products:

•  the operation of pulverized coal facilities and coke oven batteries;

•  coal sourcing, blending and transportation;

4

•  landfill gas-to-energy facilities;

•  providing expertise in the application of new energy technologies;

•  real estate development; and

•  power marketing and trading.

     The mailing address of DTE Energy Company’s principal executive offices is 2000 2nd Avenue, Detroit Michigan, 48226-1279, and its telephone number is (313) 235-8000.

DTE Energy Trusts

      DTE Energy Trust II and DTE Energy Trust III are Delaware statutory trusts, created by way of trust agreements and the filing of certificates of trust with the Delaware Secretary of State. We will execute amended and restated trust agreements for the DTE Energy Trusts, referred to in this prospectus as the trust agreements, in connection with any issuance of trust securities. These amended and restated trust agreements will state the terms and conditions for the DTE Energy Trusts to issue and sell their trust preferred securities and trust common securities. We filed a form of amended and restated trust agreement as an exhibit to the registration statement of which this prospectus forms a part.

     The DTE Energy Trusts will exist solely to:

•  issue and sell their trust preferred securities and trust common securities;

•  use the proceeds from the sale of their trust preferred securities and trust common securities to purchase and hold DTE Energy’s debt securities as trust assets; and

•  engage in other activities that are necessary or incidental to the above purposes.

     DTE Energy will hold directly or indirectly all of the trust common securities of each of the DTE Energy Trusts. The trust common securities will represent an aggregate liquidation amount equal to at least 3% of each DTE Energy Trust’s total capitalization. The trust preferred securities will represent the remaining percentage of each DTE Energy Trust’s total capitalization. The trust common securities will generally have terms substantially identical to, and will rank equal in priority of payment with, the trust preferred securities. However, if DTE Energy defaults on the debt securities owned by a DTE Energy Trust or another event of default under the trust agreement occurs, then, so long as the default continues, cash distributions and liquidation, redemption and other amounts payable or deliverable on the securities of that trust must be paid or delivered to the holders of the trust preferred securities of that trust before the holders of the common securities of that trust.

     The DTE Energy Trusts may not borrow money, issue debt, execute mortgages or pledge any of their assets.

     The trust preferred securities will be guaranteed by us as described in this prospectus and the applicable prospectus supplement.

5

     Unless otherwise specified in the applicable prospectus supplement, the following trustees will conduct each DTE Energy Trust’s business and affairs:

•  The Bank of New York, as property trustee;

•  The Bank of New York, as Delaware trustee; and

•  one or more of our officers, as administrative trustees.

     Only we, as direct or indirect owner of the trust common securities, can remove or replace the administrative trustees. In addition, we can increase or decrease the number of administrative trustees. Also, we, as direct or indirect holder of the trust common securities, will generally have sole right to remove or replace the property and Delaware trustees. However, if DTE Energy defaults on the debt securities owned by a DTE Energy Trust or another event of default under the trust agreement occurs, then, so long as that default is continuing, the holders of a majority in liquidation amount of the outstanding trust preferred securities of that trust may remove and replace the property and Delaware trustees for that trust.

     We will pay all fees and expenses related to the DTE Energy Trusts and the offering of the trust preferred securities. We will also pay all ongoing costs and expenses of the DTE Energy Trusts, except each trust’s obligations under the trust preferred securities and trust common securities.

     The Trusts’ offices are located at 2000 2nd Avenue, Detroit, Michigan, 48226, and the telephone number is (313) 235-8000.

Ratios of Earnings to Fixed Charges and

Ratios of Earnings to Combined Fixed Charges

and Preferred Stock Dividends

      Our ratios of earnings to fixed charges and ratios of earnings to combined fixed charges and preferred stock dividends were as follows for the periods indicated in the table below.

			Year Ended December 31,
	Six Months
	Ended June 30, 2002		2001		2000		1999		1998		1997
Ratio of earnings to fixed charges		1.96		1.52		2.37		2.48		2.72		3.06
Ratio of earnings to combined fixed charges and preferred stock dividends		1.90		1.50		2.37		2.48		2.68		2.95

     Our ratios of earnings to fixed charges were computed based on:

•  “earnings,” which consist of consolidated income plus income taxes and fixed charges;

•  “fixed charges,” which consist of consolidated interest on indebtedness, including capitalized interest, amortization of debt discount and expense, and the estimated portion of rental expense attributable to interest; and

6

•  “combined fixed charges and preferred stock dividends,” which consist of consolidated interest on indebtedness, including capitalized interest, amortization of debt discount and expense, and the estimated portion of rental expense attributable to interest and preferred stock dividends of consolidated subsidiaries.

Use of Proceeds

      Except as we may otherwise state in an accompanying prospectus supplement, DTE Energy expects to use the net proceeds from the sale of its securities for general corporate purposes, which may include, among other things:

•  financing and development and construction of new facilities;

•  additions to working capital; and

•  repurchase or refinancing of securities.

     The precise amount and timing of the application of such proceeds will depend upon our funding requirements, market conditions and the availability and cost of other funds. Pending the application of proceeds, we may also invest the funds temporarily in short-term investment grade securities.

     The DTE Energy Trusts will use all proceeds from the sale of the trust preferred securities to purchase debt securities of DTE Energy.

The Securities that We May Offer

      The descriptions of the securities contained in this prospectus, together with the applicable prospectus supplements, summarize certain terms and provisions of the various types of securities that DTE Energy and the DTE Energy Trusts may offer. The particular terms of the securities offered by any prospectus supplement will be described in that prospectus supplement. If indicated in the applicable prospectus supplement, the terms of the securities may differ from the terms summarized below. The prospectus supplement will also contain information, where applicable, about material U.S. federal income tax considerations relating to the securities, and any securities exchange on which the securities may be listed.

     We may sell from time to time, in one or more offerings:

•  common stock and related preferred stock purchase rights;

•  senior or subordinated debt securities, including debt securities convertible into common stock of DTE Energy or exchangeable for other securities;

•  common stock purchase contracts; and/or

•  common stock purchase units.

     The DTE Energy Trusts may offer and sell from time to time their trust preferred securities guaranteed by us.

     In this prospectus, DTE Energy and the DTE Energy Trusts refer to the common stock and related preferred stock purchase rights, senior debt securities, subordinated debt

7

securities, common stock purchase contracts, common stock purchase units, trust preferred securities and our guarantees of the trust preferred securities collectively as “securities.” We refer to the senior debt securities and the subordinated debt securities collectively as the “debt securities.”

Description of Capital Stock

Authorized Capital Stock

     The authorized capital stock of DTE Energy currently consists of 400,000,000 shares of DTE Energy common stock, without par value, and 5,000,000 shares of preferred stock, without par value. As of July 31, 2002, there were 167,466,850 shares of DTE Energy common stock issued and outstanding. All outstanding shares of common stock are, and the common stock offered hereby when issued and paid for will be, duly authorized, validly issued, fully paid and nonassessable. As of July 31, 2002, there were no shares of preferred stock issued and outstanding and 1,500,000 shares of Series A Junior Participating Preferred Stock were reserved for issuance pursuant to the rights agreement, dated September 23, 1997, between DTE Energy and The Detroit Edison Company. Each outstanding share of DTE Energy common stock currently has attached to it one preferred stock purchase right, issued under the rights agreement.

     Under the DTE Energy amended and restated articles of incorporation, which we refer to as the articles of incorporation, our board of directors may cause the issuance of one or more new series of the authorized shares of preferred stock, determine the number of shares constituting any such new series and fix the voting, distribution, dividend, liquidation and all other rights and limitations of the preferred stock. These rights may be superior to those of the DTE Energy common stock. To the extent any shares of DTE Energy’s preferred stock have voting rights, no share of preferred stock may be entitled to more than one vote per share, except that with respect to election of directors, cumulative voting may be available.

Common Stock

     The following description of our common stock, together with the additional information included in any applicable prospectus supplement, summarizes the material terms and provisions of this type of security. We will describe the specific terms of any common stock we may offer in a prospectus supplement. If indicated in a prospectus supplement, the terms of any common stock offered under that prospectus supplement may differ from the terms described below. For the complete terms of our common stock, please refer to our articles of incorporation, bylaws and rights agreement that are incorporated by reference into the registration statement that includes this prospectus or may be incorporated by reference in this prospectus. The terms of our common stock may also be affected by the laws of the State of Michigan.

Dividends

     Holders of common stock are entitled to participate equally in respect to dividends as, when and if dividends are declared by our board of directors out of funds legally available for their payment. However, this dividend right is subject to any preferential dividend rights we may grant to future holders of preferred stock and to the prior rights of DTE Energy’s debt holders and other creditors. As a Michigan corporation, we are subject to

8

statutory limitations on the declaration and payment of dividends. Dividends on DTE Energy common stock will depend primarily on the earnings and financial condition of DTE Energy. DTE Energy is a holding company and its assets consist primarily of its investment in its operating subsidiaries. Thus, as a practical matter, dividends on common stock of DTE Energy will depend in the foreseeable future primarily upon the earnings, financial condition and capital requirements of Detroit Edison, MichCon and our other subsidiaries, and the distribution of such earnings to DTE Energy in the form of dividends. The subsidiaries are separate and distinct legal entities and have no obligation to make payments with respect to any of DTE Energy’s securities, or to pay dividends to or make funds available to DTE Energy so that DTE Energy can make payments on its securities, including its common stock. In addition, existing or future covenants limiting the right of Detroit Edison, MichCon or our other subsidiaries to pay dividends on or make other distributions with respect to their common stock may affect DTE Energy’s ability to pay dividends on our common stock. See “Description of Debt Securities — Ranking.”

Voting

     Subject to any special voting rights that may vest in the holders of preferred stock, the holders of DTE Energy common stock are entitled to vote as a class and are entitled to one vote per share for each share held of record on all matters voted on by shareholders, except that with respect to the election of directors, cumulative voting is available. All questions other than election of directors are decided by a majority of the votes cast by the holders of shares entitled to vote on that question, unless a greater vote is required by the articles of incorporation or Michigan law. Directors are elected by a plurality of the votes cast.

     We are subject to Chapter 7A of the Michigan Business Corporation Act, which we refer to as the Act, which provides that business combinations subject to Chapter 7A between a Michigan corporation and a beneficial owner of shares entitled to 10% or more of the voting power of such corporation generally require the affirmative vote of 90% of the votes of each class of stock entitled to vote, and not less than 2/3 of each class of stock entitled to vote (excluding voting shares owned by such 10% owner), voting as a separate class. These requirements do not apply if (1) the corporation’s board of directors approves the transaction prior to the time the 10% owner becomes such or (2) the transaction satisfies certain fairness standards, certain other conditions are met and the 10% owner has been such for at least five years.

     In addition, our bylaws provide that Chapter 7B of the Act does not apply to DTE Energy. Chapter 7B of the Act regulates shareholder rights when an individual’s stock ownership reaches at least 20% of a Michigan corporation’s outstanding shares. Accordingly, pursuant to DTE Energy’s bylaws, a shareholder seeking control of DTE Energy cannot require the DTE Energy’s board of directors to call a meeting to vote on issues related to corporate control within 10 days of such request, as stipulated by Chapter 7B of the Act.

Board of Directors

     Our bylaws provide for a board of directors that is divided into three classes. Each class is to serve a three-year term and the classes are to be as nearly equal in size as possible. The number of directors is fixed by the board of directors from time to time but not less than 10 nor more than 18, subject to the board of director’s authority to change

9

the minimum and maximum number of directors. DTE Energy currently has 12 directors. Under our bylaws, the provision providing for the classification of the board of directors may not be amended or repealed without the vote of a majority of the shares of DTE Energy’s common stock.

Amendments to DTE Energy’s Articles of Incorporation

     Under Michigan law, our articles of incorporation may be amended by the affirmative vote of the holders of a majority of the outstanding shares entitled to vote on the proposed amendment (which would include the common stock and any series of preferred stock which, by its terms or applicable law, was so entitled to vote), and, if any class or series of shares is entitled to vote as a class, then the proposed amendment must be approved by the required vote of each class or series of shares entitled to vote as a class.

Liquidation Rights

     In the event of a liquidation, dissolution or winding-up of DTE Energy, holders of our common stock have the right to share in DTE Energy’s assets remaining after satisfaction in full of the prior rights of creditors, and all liabilities and the aggregate liquidation preferences of any outstanding shares of DTE Energy preferred stock.

Preemptive Rights

     The holders of DTE Energy common stock have no conversion or redemption rights, or any rights to subscribe for or purchase other stock of DTE Energy.

Listing

     Our common stock is listed on the New York Stock Exchange and the Chicago Stock Exchange under the symbol “DTE.”

Transfer Agent and Registrar

     The transfer agent and registrar for our common stock is The Bank of New York, 101 Barclay Street, 8W, New York, New York 10286.

Rights Agreement

General

     The following is a description of the preferred stock purchase rights issued or to be issued under the DTE Energy rights agreement. This description does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the text of the DTE Energy rights agreement, which is incorporated herein by reference and filed as an exhibit to the registration statement of which this prospectus is a part.

     Our rights agreement provides for the issuance to holders of DTE Energy common stock of one preferred stock purchase right for each share of DTE Energy common stock. Subject to the conditions contained in DTE Energy’s rights agreement, each right entitles the holder to purchase from DTE Energy one one-hundredth of a share of DTE Energy Series A Junior Participating Preferred Stock, without par value, at a purchase price of $90.00, subject to adjustment as described below. The rights, which are attached to and

10

trade with the shares of DTE Energy common stock until they are exercisable, may not be exercised until the close of business on the earlier of:

•  the 10th calendar day after the first date of public announcement by DTE Energy that a person, together with its affiliates and associates, has acquired beneficial ownership of 10% or more of the outstanding shares of DTE Energy common stock, which we refer to as an “acquiring person”; or

•  the 10th business day (or, unless the date specified in the bullet point above has previously occurred, such later date as may be specified by our board of directors) after the date that any person commences a tender offer or exchange offer, the consummation of which would result in beneficial ownership by such person of 10% or more of the outstanding shares of DTE Energy common stock.

     We refer to the earlier of these two dates as the “distribution date.”

     DTE Energy, its subsidiaries, employee benefit or stock ownership plans, and affiliates or associates of DTE Energy are not acquiring persons. Rights beneficially owned by acquiring persons, or certain transferees of acquiring persons, are void.

“Flip-in”

     In the event that:

•  any person becomes an acquiring person;

•  any acquiring person merges into or combines with DTE Energy, and DTE Energy is the surviving corporation;

•  any acquiring person effects certain other transactions with DTE Energy; or

•  during such time as there is an acquiring person, DTE Energy effects certain transactions

then each unexercised right (other than those held by the acquiring person) will entitle its holder to purchase that number of shares of DTE Energy common stock or, under certain circumstances, an economically equivalent security of DTE Energy, which has a market value at that time of twice the purchase price.

“Flip-over”

     In the event that, at any time after a person has become an acquiring person:

•  DTE Energy merges with or into any person and DTE Energy is not the surviving corporation;

•  any person merges with or into DTE Energy and DTE Energy is the surviving corporation, but all or part of the DTE Energy common stock is exchanged for securities of any other person, cash or any other property; or

•  50% or more of DTE Energy’s assets or earning power are sold

then each unexercised right would instead entitle its holder to purchase the acquiring company’s common shares having a market value of twice the purchase price.

11

Exchange

     If a person or group acquires beneficial ownership of more than 10% but less than 50% of the outstanding shares of DTE Energy common stock, DTE Energy may exchange each outstanding right for one share of DTE Energy common stock.

Redemption

     DTE Energy may redeem the rights, at a redemption price of $0.01 per right, subject to adjustment, at any time prior to the later of the first occurrence of any Flip-in event or Flip-over event and the distribution date.

Certain Adjustments

     The purchase price, and the number of shares of preferred stock or other securities issuable upon exercise of the right, will be adjusted to prevent dilution:

•  in the event of a stock dividend on, or a subdivision, combination or reclassification of, the preferred stock;

•  upon the grant to holders of the preferred stock of certain rights or warrants to subscribe for preferred stock at a price, or securities convertible into preferred stock with a conversion price, less than the then-current market price of the preferred stock; or

•  upon the distribution to holders of the preferred stock of evidence of indebtedness, cash (excluding regular periodic cash dividends), assets, stock (excluding dividends payable in preferred stock) or subscription rights or warrants (other than those referred to above).

     With certain exceptions, no adjustments in the purchase price will be required until cumulative adjustments amount to at least 1% of the purchase price. DTE Energy will not be required to issue fractional shares of preferred stock other than in integral multiples of one one-hundredth of a share. Instead, DTE Energy will make a cash payment, as provided in the rights agreement.

Amounts Outstanding

     DTE Energy distributed one right to shareholders of the company for each share of common stock owned of record by them at the close of business on October 6, 1997. Until the earliest of

•  the distribution date;

•  October 6, 2007; or

•  such time as all rights are redeemed or exchanged,

     DTE Energy will issue one right with each share of DTE Energy common stock that is issued after October 6, 1997, so that each outstanding share of common stock will have a related right. DTE Energy has authorized and reserved 1,500,000 shares of Series A Junior Participating Preferred Stock for issuance upon exercise of the rights.

12

     DTE Energy may amend the rights agreement without the approval of any holders of rights certificates, except that no amendment may be made that decreases the stated redemption price to an amount less than $.01 per right.

Possible Anti-Takeover Effects

     Certain provisions of our articles of incorporation and bylaws may have the effect of discouraging unilateral tender offers or other attempts to take over and acquire the business of DTE Energy. As permitted by the Act, our bylaws restrict shareholders from bringing any business before a special meeting of shareowners, require prior written notice of any business to be brought by a shareowner before the annual meeting and require advance notice for shareowner nominations for directors. In addition, the articles of incorporation or bylaws authorize our board of directors to issue one or more series of preferred stock, provide for a staggered board of directors, and provide that Chapter 7B of the Act does not apply to DTE Energy, as discussed above. These provisions in our articles of incorporation or bylaws may limit the ability of individuals to bring matters before shareowner meetings, change the composition of the board of directors and pursue a merger, takeover, business combination or tender offer involving DTE Energy, which, under certain circumstances, could encourage a potentially interested purchaser to negotiate with the board of directors rather than pursue a non-negotiated takeover attempt, including one that shareowners might favor, and could reduce the market value of our common stock.

     In addition, the provisions of the DTE Energy rights agreement have certain anti-takeover effects. The preferred stock purchase rights may cause substantial dilution to a person or group that attempts to acquire DTE Energy on terms not approved by our board of directors, except pursuant to an offer conditional on a substantial number of preferred stock purchase rights being acquired or redeemed.

Description of Debt Securities

      The following description, together with any applicable prospectus supplement, summarizes certain material terms and provisions of the debt securities we may offer under this prospectus and the related trust indenture. We will issue the debt securities under an amended and restated indenture, dated as of April 9, 2001, as supplemented or amended from time to time, which we refer to as the “indenture,” between DTE Energy and The Bank of New York, as trustee. We refer to The Bank of New York, or any successor or additional trustee, in its capacity as trustee under the indenture, as the “trustee” for purposes of this section. The indenture may, but need not, have separate trustees for senior and subordinated debt securities.

     This summary of the indenture and the debt securities relates to terms and conditions applicable to the debt securities generally. The particular terms of any series of debt securities will be summarized in the applicable prospectus supplement. If indicated in the prospectus supplement, the terms of any series may differ from the terms summarized below.

     Because the descriptions of provisions of the indenture below are summaries, they do not describe every aspect of the indenture. The summaries below are subject to, and are qualified in their entirety by reference to, all provisions of the indenture, including the definitions therein of certain terms. We have filed a copy of the indenture as an exhibit to

13

the registration statement of which this prospectus is a part. We encourage you to read the indenture for provisions that may be important to you. Wherever we refer to particular articles, sections or defined terms of the indenture, those articles, sections or defined terms are incorporated herein by reference, and the statement in connection with which such reference is made is qualified in its entirety by such reference. The indenture contains, and the debt securities, when issued, will contain, additional important terms and provisions. We will describe the particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which such general provisions may apply to the debt securities so offered in the prospectus supplement relating to those debt securities.

     The indenture does not limit the amount of debt securities we may issue under it, and it provides that additional debt securities of any series may be issued up to the aggregate principal amount that we may authorize from time to time. As of July 31, 2002, approximately $2.1 billion aggregate principal amount of debt securities were issued and outstanding under the indenture.

     Unless otherwise indicated in the applicable prospectus supplement, we will issue registered debt securities in denominations of $1,000 and integral multiples of $1,000 and bearer securities in denominations of $5,000.

     Principal and any premium and interest in respect to the debt securities will be payable, and the debt securities will be transferable, at the corporate trust office of the trustee, unless we specify otherwise in the applicable prospectus supplement. At our option, however, payment of interest may be made by check mailed to the registered holders of the debt securities at their registered addresses.

     We will describe special U.S. federal income tax and other considerations relating to debt securities denominated in foreign currencies or units of two or more foreign currencies in the applicable prospectus supplement.

     Unless we otherwise specify in this prospectus or in the applicable prospectus supplement, we will issue debt securities in the form of global securities, deposited with and registered in the name of The Depository Trust Company, as depositary, which we refer to as “DTC,” or its nominee. Interests in the debt securities will be shown on, and transfers thereof will be effected only through, records maintained by DTC and its participants. See “Book-Entry Securities.”

     We are not obligated to issue all debt securities of any one series at the same time and all the debt securities of any one series need not bear interest at the same rate or mature on the same date.

     Under the indenture, the terms of the debt securities of any series may differ and we, without the consent of the holders of the debt securities of any series, may reopen a previous series of debt securities and issue additional debt securities of such series or establish additional terms of such series.

16

     Other than as described below under “— Covenants” with respect to any applicable series of debt securities and as may be described in the applicable prospectus supplement, the indenture does not limit our ability to incur indebtedness or afford holders of debt securities protection in the event of a decline in our credit quality or if we are involved in a takeover, recapitalization or highly leveraged or similar transaction. Accordingly, we could in the future enter into transactions that could increase the amount of indebtedness outstanding at that time or otherwise affect our capital structure or credit rating. You should refer to the prospectus supplement relating to a particular series of debt securities for information regarding the applicability of the covenant described below under “— Covenants — Limitation on Secured Debt” or any deletions from, modifications of or additions to the events of default described below or covenants contained in the indenture, including any addition of a covenant or other provisions providing event risk or similar protection.

Ranking

     Because DTE Energy is a holding company that conducts substantially all of its operations through subsidiaries, holders of debt securities and guarantees of DTE Energy will generally have a junior position to claims of creditors of those subsidiaries, including trade creditors, debtholders, secured creditors, taxing authorities, guarantee holders and preferred stockholders, if any. Our subsidiaries, principally Detroit Edison and MichCon, from time to time incur debt to finance their business activities. Substantially all of the physical properties of Detroit Edison and MichCon are subject to the liens of their respective mortgage indentures as security for the payment of outstanding mortgage bonds.

     Our assets consist primarily of investment in subsidiaries. Our ability to service indebtedness, including any debt securities and guarantees, depends on the earnings of our subsidiaries and the distribution or other payment from subsidiaries of earnings to us in the form of dividends, loans or advances, and repayment of loans and advances from us. The subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due under the debt securities or to make payments to us in order for us to pay our obligations under the debt securities. In addition, Detroit Edison has the right to defer interest payments on its outstanding junior subordinated debentures. In the event it exercises this right, Detroit Edison may not declare or pay dividends on, or redeem, purchase or acquire, any of its capital stock during the deferral period. Enterprises has outstanding debentures that have similar restrictions.

Senior Debt Securities

     Unless otherwise indicated in the applicable prospectus supplement, our obligation to pay the principal of, and any premium and interest on, the senior debt securities will be unsecured and will rank equally with all of our other unsecured unsubordinated indebtedness.

Subordinated Debt Securities

     Our obligation to pay the principal of, and any premium and interest on, any series of subordinated debt securities will be unsecured and will rank subordinate and junior in right of payment to all Senior Indebtedness (as defined below) to the extent provided in the supplemental indenture relating to the series and the terms of those subordinated debt securities, as described below and in any applicable prospectus supplement, which may

17

make deletions from, or modifications or additions to, the subordination terms described below.

     Upon any payment or distribution of assets or securities of DTE Energy to creditors upon any liquidation, dissolution, winding-up, reorganization, or any bankruptcy, insolvency, receivership or similar proceedings in connection with any insolvency or bankruptcy proceeding of DTE Energy, the holders of Senior Indebtedness will first be entitled to receive payment in full of the Senior Indebtedness before the holders of subordinated debt securities will be entitled to receive any payment or distribution in respect of the subordinated debt securities, and to that end the holders of Senior Indebtedness will be entitled to receive, for application to the payment thereof, any payment or distribution of any kind or character, whether in cash, property or securities, including any such payment or distribution that may be payable or deliverable by reason of the payment of any other Indebtedness of DTE Energy being subordinated to the payment of subordinated debt securities of such series, which may be payable or deliverable in respect of the subordinated debt securities of such series upon any such dissolution, winding-up, liquidation or reorganization or in any such bankruptcy, insolvency, receivership or other proceeding.

     By reason of such subordination, in the event of liquidation or insolvency of DTE Energy, holders of Senior Indebtedness with respect to the subordinated debt securities of any series and holders of other obligations of DTE Energy that are not subordinated to such Senior Indebtedness may recover more, ratably, than the holders of the subordinated debt securities of such series.

     Subject to the payment in full of all Senior Indebtedness with respect to the subordinated debt securities of any series, the rights of the holders of the subordinated debt securities of such series will be subrogated to the rights of the holders of Senior Indebtedness to receive payments or distributions of cash, property or securities of DTE Energy applicable to such Senior Indebtedness until the principal of, any premium and interest on, and any additional amounts with respect to, the subordinated debt securities of such series have been paid in full.

     No payments on account of principal or any premium or interest in respect of the subordinated debt securities may be made if there has occurred and is continuing a default in any payment with respect to Senior Indebtedness or an event of default with respect to any Senior Indebtedness resulting in the acceleration of its maturity, or if any judicial proceeding is pending with respect to any default.

     “Indebtedness” means:

•  indebtedness for borrowed money;

•  obligations for the deferred purchase price of property or services (other than trade payables not overdue by more than 60 days incurred in the ordinary course of business);

•  obligations evidenced by notes, bonds, debentures or other similar instruments;

•  obligations created or arising under any conditional sale or other title retention agreement with respect to acquired property;

18

•  obligations as lessee under leases that have been or should be, in accordance with accounting principles generally accepted in the United States, recorded as capital leases;

•  obligations, contingent or otherwise, in respect of acceptances, letters of credit or similar extensions of credit;

•  obligations in respect of interest rate swap, cap or collar agreements, interest rate future or option contracts, currency swap agreements, currency future or option contracts and other similar agreements;

•  guarantees of Indebtedness of others, directly or indirectly, or Indebtedness in effect guaranteed directly or indirectly through an agreement (1) to pay or purchase such Indebtedness or to advance or supply funds for the payment or purchase of such Indebtedness, (2) to purchase, sell or lease property, or to purchase or sell services, primarily for the purpose of enabling the debtor to make payment of such Indebtedness or to assure the holder of such Indebtedness against loss, (3) to supply funds to or in any other manner invest in the debtor or (4) otherwise to assure a creditor against loss; and

•  Indebtedness described above secured by any Lien (as defined below) on property.

     “Senior Indebtedness,” for purposes of subordinated debt securities of each series, means all Indebtedness, whether outstanding on the date of issuance of subordinated debt securities of the applicable series or thereafter created, assumed or incurred, except Indebtedness ranking equally with the subordinated debt securities or Indebtedness ranking junior to the subordinated debt securities. Senior Indebtedness does not include obligations to trade creditors or indebtedness of DTE Energy to its subsidiaries. Senior Indebtedness with respect to the subordinated debt securities of any particular series will continue to be Senior Indebtedness with respect to the subordinated debt securities of such series and be entitled to the benefits of the subordination provisions irrespective of any amendment, modification or waiver of any term of such Senior Indebtedness.

     “Indebtedness ranking equally with the subordinated debt securities,” for purposes of subordinated debt securities of the applicable series, means Indebtedness, whether outstanding on the date of issuance of the subordinated debt securities or thereafter created, assumed or incurred, to the extent the Indebtedness specifically by its terms ranks equally with and not prior to the subordinated debt securities in the right of payment upon the happening of the dissolution, winding-up, liquidation or reorganization of DTE Energy. The securing of any Indebtedness otherwise constituting Indebtedness ranking equally with the subordinated debt securities will not prevent the Indebtedness from constituting Indebtedness ranking equally with the subordinated debt securities.

     “Indebtedness ranking junior to the subordinated debt securities,” for purposes of subordinated debt securities of the applicable series, means any Indebtedness, whether outstanding on the date of issuance of the subordinated debt securities of the applicable series or thereafter created, assumed or incurred, to the extent the Indebtedness by its terms ranks junior to and not equally with or prior to

•  the subordinated debt securities, and

•  any other Indebtedness ranking equally with the subordinated debt securities,

19

in right of payment upon the happening of the dissolution, winding-up, liquidation or reorganization of DTE Energy. The securing of any Indebtedness otherwise constituting Indebtedness ranking junior to the subordinated debt securities will not prevent the Indebtedness from constituting Indebtedness ranking junior to the subordinated debt securities.

Covenants

     The indenture contains covenants for the benefit of holders of debt securities of each series. The following covenant will apply to a series of debt securities only to the extent specified in the applicable prospectus supplement.

Limitation on Secured Debt

     If this covenant is made applicable to the debt securities of any particular series, we have agreed that we will not create, issue, incur or assume any Secured Debt (as defined below) without the consent of the holders of a majority in principal amount of the outstanding debt securities of all series with respect to which this covenant is made, considered as one class; provided, however, that the foregoing covenant will not prohibit the creation, issuance, incurrence or assumption of any Secured Debt if we either:

•  secure all debt securities then outstanding with respect to which this covenant is made equally and ratably with the Secured Debt; or

•  deliver to the trustee bonds, notes or other evidences of indebtedness secured by the Lien (as defined below) which secures the Secured Debt in an aggregate principal amount equal to the aggregate principal amount of the debt securities then outstanding with respect to which this covenant is made and meeting certain other requirements in the indenture.

     “Debt” means

•  indebtedness for borrowed money evidenced by a bond, debenture, note or other written instrument or agreement by which we are obligated to repay such borrowed money; and

•  any guaranty by DTE Energy of any such indebtedness of another person.

     “Lien” means any mortgage, pledge, security interest, encumbrance, lien or charge of any kind (including, without limitation, any conditional sale or other title retention agreement or lease in the nature thereof or any agreement to give any security interest).

     “Secured Debt” means Debt created, issued, incurred or assumed by DTE Energy that is secured by a Lien upon any shares of stock of any Significant Subsidiary, as defined in Regulation S-X of the rules and regulations under the Securities Act, whether owned at the date of the initial authentication and delivery of the debt securities of any series or thereafter acquired.

Consolidation, Merger and Sale of Assets

     DTE Energy may, without the consent of the holders of the debt securities, consolidate or merge with or into, or convey, transfer or lease our properties and assets as an entirety or substantially as an entirety to, any person or permit any person to

20

consolidate with or merge into us or convey, transfer or lease its properties and assets substantially as an entirety to us, as long as:

•  in the case DTE Energy shall merge into or consolidate with, or transfer its properties and assets as an entirety (or substantially as an entirety) to any person, such person is a corporation, partnership or trust, organized and validly existing under the laws of the United States of America, any state thereof or the District of Columbia;

•  any successor person (if not DTE Energy) assumes by supplemental indenture, the due and punctual payment of the principal of, any premium and interest on and any additional amounts with respect to all the debt securities issued thereunder, and the performance of our obligations under the indenture and the debt securities issued thereunder, and provides for conversion or exchange rights in accordance with the provisions of the debt securities of any series that are convertible or exchangeable into common stock or other securities;

•  no event of default under the indenture has occurred and is continuing after giving effect to the transaction;

•  no event which, after notice or lapse of time or both, would become an event of default under the indenture has occurred and is continuing after giving effect to the transaction; and

•  certain other conditions are met.

     Upon any merger or consolidation described above or conveyance or transfer of the properties and assets of DTE Energy as or substantially as an entirety as described above, the successor person will succeed to DTE Energy’s obligations under the indenture and, except in the case of a lease, the predecessor person will be relieved of such obligations.

     The indenture does not prevent or restrict any conveyance or other transfer, or lease, of any part of the properties of DTE Energy which does not constitute the entirety, or substantially the entirety, thereof.

Events of Default

     Unless otherwise specified in the applicable prospectus supplement, an event of default with respect to any series of debt securities will be any of the following events:

     (1) failure to pay interest on the debt securities of that series, or any additional amounts payable with respect to the debt securities, for 30 days after payment is due;

     (2) failure to pay principal or any premium on the debt securities of that series, or any additional amounts payable with respect to the debt securities, when due;

     (3) failure to pay any sinking fund installment or analogous payment when due;

     (4) failure to perform, or breach, of any other covenant or warranty or obligation of DTE Energy in the indenture for 60 days after we are given written notice by the trustee or we and the trustee are given written notice by the registered owners of at least 25% in principal amount of the debt securities of that series;

     (5) default occurs under any bond, note, debenture or other instrument evidencing any indebtedness for money borrowed by DTE Energy (including a default

21

with respect to any other series of debt securities issued under the indenture), or under any mortgage, indenture or other instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by DTE Energy (or the payment of which is guaranteed by DTE Energy), whether such indebtedness or guarantee exists on the date of the indenture or is issued or entered into following the date of the indenture, if:

     either:

•  such default results from failure to pay any such indebtedness when due and such defaulted payment has not been made, waived or extended within 30 days of such payment default; or

•  as a result of such default the maturity of such indebtedness has been accelerated prior to its expressed maturity and such indebtedness shall not have been discharged in full or such acceleration has not been rescinded or annulled within 30 days of such acceleration; and

•  the principal amount of such indebtedness, together with the principal amount of any other such indebtedness in default for failure to pay any such indebtedness when due or the maturity of which has been so accelerated, aggregates at least $40 million;

     (6) certain events of bankruptcy, insolvency, reorganization, receivership or liquidation relating to DTE Energy; or

     (7) any other event of default provided with respect to debt securities of that series.

     If an event of default with respect to the debt securities of any series, other than an event of default described in paragraph (6) above pertaining to certain events of bankruptcy, insolvency or reorganization, occurs and is continuing, either the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series may declare the principal amount of the debt securities of that series to be due and payable immediately. At any time after a declaration of acceleration has been made, but before a judgment or decree for payment of money has been obtained by the trustee, and subject to applicable law and certain other provisions of the indenture, the holders of a majority in aggregate principal amount of the debt securities of that series may, under certain circumstances, rescind and annul the acceleration. If an event of default occurs pertaining to certain events of bankruptcy, insolvency or reorganization specified in the indenture, the principal amount and accrued and unpaid interest and any additional amounts payable in respect of the debt securities of that series — or a lesser amount as provided for in the debt securities of that series — will be immediately due and payable without any declaration or other act by the trustee or any holder.

     The indenture provides that within 90 days after the occurrence of any default under the indenture with respect to the debt securities of any series, the trustee must transmit to the holders of the debt securities of such series, in the manner set forth in the indenture, notice of the default known to the trustee, unless the default has been cured or waived. But, in the case of a default in the payment of the principal of (or premium, if any) or interest or any additional amounts or in the payment of any sinking fund installment, on any debt security of such series, the trustee may withhold such notice if and so long as the board of directors, the executive committee or a trust committee of directors or responsible

22

officers of the trustee has in good faith determined that the withholding of such notice is in the interest of the holders of debt securities of such series. And further, in the case of any event of default as described in paragraph (4) above, no such notice to holders will be given until at least 30 days after the occurrence of the event of default.

     If an event of default occurs and is continuing with respect to the debt securities of any series, the trustee may in its discretion proceed to protect and enforce its rights and the rights of the holders of debt securities of such series by all appropriate judicial proceedings.

     The indenture further provides that, subject to the duty of the trustee during any default to act with the required standard of care, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders of debt securities, unless that requesting holder has offered to the trustee reasonable indemnity. Subject to such provisions for the indemnification of the trustee, and subject to applicable law and certain other provisions of the indenture, the holders of a majority in aggregate principal amount of the outstanding debt securities of a series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the debt securities of such series.

     The indenture provides that no holder of any debt security of a series will have any right to institute any proceeding with respect to the indenture for the appointment of a receiver or for any other remedy thereunder unless

•  that holder has previously given the trustee written notice of a continuing event of default;

•  the holders of 25% in aggregate principal amount of the outstanding debt securities of that series have made written request to the trustee to institute proceedings in respect of that event of default and have offered the trustee reasonable indemnity against costs and liabilities incurred in complying with such request; and

•  for 60 days after receipt of such notice, the trustee has failed to institute any such proceeding and no direction inconsistent with such request has been given to the trustee during such 60-day period by the holders of a majority in aggregate principal amount of outstanding debt securities of that series.

     Furthermore, no holder will be entitled to institute any such action if and to the extent that such action would disturb or prejudice the rights of other holders.

     However, each holder has an absolute and unconditional right to receive payment when due and to bring a suit to enforce that right.

     Under the indenture, we are required to furnish to the trustee annually a statement as to our performance of certain of our obligations under the indenture and as to any default in such performance. We are also required to deliver to the trustee, within five days after occurrence thereof, written notice of any event that after notice or lapse of time or both would constitute an event of default.

Interest Rates and Discounts

     The debt securities will earn interest at a fixed or floating rate or rates for the period or periods of time specified in the applicable prospectus supplement. Unless otherwise

23

specified in the applicable prospectus supplement, the debt securities will bear interest on the basis of a 360-day year consisting of twelve 30-day months.

     We may sell debt securities at a substantial discount below their stated principal amount, bearing no interest or interest at a rate that at the time of issuance is below market rates. U.S. Federal income tax consequences and special considerations that apply to any series will be described in the applicable prospectus supplement.

Exchange, Registration and Transfer

     Registered securities of any series that are not global securities will be exchangeable for other registered securities of the same series and of like aggregate principal amount and tenor in different authorized denominations. In addition, if debt securities of any series are issuable as both registered securities and bearer securities, the holder may choose, upon written request, and subject to the terms of the indenture, to exchange bearer securities and the appropriate related coupons of that series into registered securities of the same series of any authorized denominations and of like aggregate principal amount and tenor. Bearer securities with attached coupons surrendered in exchange for registered securities between a regular record date or a special record date and the relevant date for interest payment shall be surrendered without the coupon relating to the interest payment date. Interest will not be payable with respect to the registered security issued in exchange for that bearer security. That interest will be payable only to the holder of the coupon when due in accordance with the terms of the indenture. Bearer securities will not be issued in exchange for registered securities.

     Holders may present registered securities for registration of transfer, together with a duly executed form of transfer, at the office of the security registrar or at the office of any transfer agent designated by us for that purpose with respect to any series of debt securities and referred to in the applicable prospectus supplement. This may be done without service charge but upon payment of any taxes and other governmental charges as described in the indenture. The security registrar or the transfer agent will effect the transfer or exchange upon being satisfied with the documents of title and identity of the person making the request. We have appointed the trustee as security registrar for the indenture. If a prospectus supplement refers to any transfer agents initially designated by us with respect to any series of debt securities in addition to the security registrar, we may at any time rescind the designation of any of those transfer agents or approve a change in the location through which any of those transfer agents acts. However, if debt securities of a series are issuable solely as registered securities, we will be required to maintain a transfer agent in each place of payment for that series, and if debt securities of a series are issuable as bearer securities, we will be required to maintain a transfer agent in a place of payment for that series located outside the United States in addition to the security registrar. We may at any time designate additional transfer agents with respect to any series of debt securities.

     In the event of any redemption, we will not be required to:

•  issue, register the transfer of or exchange debt securities of any series during a period beginning at the opening of business 15 days before any selection of debt securities of that series to be redeemed and ending at the close of business on:

•  the day of the mailing of the relevant notice of redemption if the debt securities are issuable only as registered securities; or

24

•  the day of the first publication of the notice of redemption if the debt securities are issuable as bearer securities, or, if the debt securities are also issuable as registered securities and there is no publication, the mailing of the notice of redemption;

•  register the transfer of or exchange any registered security, or portion thereof, called for redemption, except the unredeemed portion of any registered security being redeemed in part;

•  exchange any bearer security called for redemption, except to exchange such bearer security for a registered security of that series and like tenor that is simultaneously surrendered for redemption; or

•  issue, register the transfer of or exchange any debt security that has been surrendered for repayment at the option of the holder, except the portion, if any, of such debt security not to be so repaid.

Payment and Paying Agents

     Unless we specify otherwise in the applicable prospectus supplement, payment of principal of, and any premium and interest on, bearer securities will be payable in accordance with any applicable laws and regulations, at the offices of those paying agents outside the United States that we may designate at various times. We will make interest payments on bearer securities and the attached coupons on any interest payment date only against surrender of the coupon relating to that interest payment date. No payment with respect to any bearer security will be made at any of our offices or agencies in the United States, by check mailed to any U.S. address or by transfer to an account maintained with a bank located in the United States. If, however, but only if, payment in U.S. dollars of the full amount of principal of, and any premium and interest on, bearer securities denominated and payable in U.S. dollars at all offices or agencies outside the United States is illegal or effectively precluded by exchange controls or other similar restrictions, then those payments will be made at the office of our paying agent in the Borough of Manhattan, The City of New York.

     Unless we specify otherwise in the applicable prospectus supplement, payment of principal of, and any premium and interest on, registered securities will be made at the office of the paying agent or paying agents that we designate at various times. However, at our option, we may make interest payments by check mailed to the address, as it appears in the security register, of the person entitled to the payments. Unless we specify otherwise in the applicable prospectus supplement, we will make payment of any installment of interest on registered securities to the person in whose name that registered security is registered at the close of business on the regular record date for such interest.

     Unless we specify otherwise in the applicable prospectus supplement, the corporate trust office of the trustee in the Borough of Manhattan, The City of New York, will be designated:

•  as our sole paying agent for payments with respect to debt securities that are issuable solely as registered securities; and

•  as our paying agent in the Borough of Manhattan, The City of New York, for payments with respect to debt securities, subject to the limitation described above

25

in the case of bearer securities, that are issuable solely as bearer securities or as both registered securities and bearer securities.

     We will name any paying agents outside the United States and any other paying agents in the United States initially designated by us for the debt securities in the applicable prospectus supplement. We may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts. However, if debt securities of a series are issuable solely as registered securities, we will be required to maintain a paying agent in each place of payment for that series. If debt securities of a series are issuable as bearer securities, we will be required to maintain:

•  a paying agent in the Borough of Manhattan, The City of New York, for payments with respect to any registered securities of the series and for payments with respect to bearer securities of the series in the circumstance described above, but not otherwise; and

•  a paying agent in a place of payment located outside the United States where debt securities of that series and any attached coupons may be presented and surrendered for payment.

     However, if the debt securities of that series are listed on The Stock Exchange of the United Kingdom and the Republic of Ireland, the Luxembourg Stock Exchange or any other stock exchange located outside the United States, and if the stock exchange requires it, we will maintain a paying agent in London or Luxembourg or any other required city located outside the United States for those debt securities.

     All monies we pay to a paying agent for the payment of principal of, and any premium or interest on, any debt security or coupon that remains unclaimed at the end of two years after becoming due and payable will be repaid to us. After that time, the holder of the debt security or coupon will look only to us for payments out of those repaid amounts.

Global Securities

     The debt securities of a series may be issued in whole or in part in the form of one or more global certificates that we will deposit with a depository identified in the applicable prospectus supplement. Global securities may be issued in either registered or bearer form and in either temporary or permanent form. Unless and until it is exchanged in whole or in part for the individual debt securities it represents, a global security may not be transferred except as a whole:

•  by the applicable depository to a nominee of the depository;

•  by any nominee to the depository itself or another nominee; or

•  by the depository or any nominee to a successor depository or any nominee of the successor.

     To the extent not described below and under the heading “Book-Entry Securities,” we will describe the terms of the depository arrangement with respect to a series of debt securities in the applicable prospectus supplement. We anticipate that the following provisions will generally apply to depository arrangements.

26

     As long as the depository for a global security, or its nominee, is the registered owner of that global security, the depository or nominee will be considered the sole owner or holder of the debt securities represented by the global security for all purposes under the indenture. Except as provided under “Book-Entry Securities” or in any applicable prospectus supplement, owners of beneficial interests in a global security:

•  will not be entitled to have any of the underlying debt securities registered in their names;

•  will not receive or be entitled to receive physical delivery of any of the underlying debt securities in definitive form;

•  will not be considered the owners or holders under the indenture relating to those debt securities; and

•  will not be able to transfer or exchange the global debt securities, except in the limited circumstances as described in this prospectus or any supplement.

     The laws of some states require that certain purchasers of securities take physical delivery of securities in definitive form. These laws may impair the owner’s ability to transfer beneficial interests in a global security.

     Payments of principal of, and any premium and interest on, individual debt securities represented by a global security registered in the name of a depository or its nominee will be made to the depository or its nominee as the registered owner of the global security representing such debt securities. Neither we, the trustee, any paying agent nor the registrar for the debt securities will be responsible for any aspect of the records relating to or payments made by the depository or any participants on account of beneficial interests of the global security.

     For a description of the depository arrangements for global securities held by The Depository Trust Company, see “Book-Entry Securities.”

Discharge, Defeasance and Covenant Defeasance

     We may discharge certain obligations to holders of any series of debt securities that have not already been delivered to the trustee for cancellation and that:

•  have become due and payable;

•  will become due and payable within one year; or

•  are scheduled for redemption within one year.

     To discharge the obligations with respect to a series of debt securities, we must deposit with the trustee, in trust, an amount of funds in U.S. dollars or in the foreign currency in which those debt securities are payable. The deposited amount must be sufficient to pay the entire amount of principal of, and any premium, interest and additional amounts on, those debt securities to the date of the deposit if those debt securities have become due and payable or to the maturity or redemption date of the debt securities, as the case may be; provided, however, we have paid all other sums payable under the indenture with respect to the debt securities, and certain other conditions are met.

27

     Unless we specify otherwise in the applicable prospectus supplement, we may elect:

•  to defease and be discharged from any and all obligations with respect to those debt securities, which we refer to as “defeasance”; or

•  with respect to any debt securities, to be released from certain covenant obligations as described in the related prospectus supplement, as may be provided for under Section 301 of the indenture, which we refer to as “covenant defeasance.”

     In the case of defeasance we will still retain some obligations in respect of the debt securities, including our obligations:

•  to pay additional amounts, if any, upon the occurrence of certain events of taxation, assessment or governmental charge with respect to payments on the debt securities;

•  to register the transfer or exchange of the debt securities;

•  to replace temporary or mutilated, destroyed, lost or stolen debt securities; and

•  to maintain an office or agency with respect to the debt securities and to hold monies for payment in trust.

     After a covenant defeasance, any omission to comply with the obligations or covenants that have been defeased shall not constitute a default or an event of default with respect to the debt securities.

     To elect either defeasance or covenant defeasance we must deposit with the trustee, in trust, an amount, in U.S. dollars or in the foreign currency in which the relevant debt securities are payable at stated maturity, or in government obligations, as defined below, or both, applicable to such debt securities. The deposit will provide through the scheduled payment of principal and interest in accordance with their terms, money in an amount sufficient to pay the principal of and any premium and interest on (and, to the extent that (1) the debt securities of such series provide for the payment of additional amounts and (2) we may reasonably determine the amount of any such additional amounts at the time of deposit (in the exercise of our sole discretion), any such additional amounts with respect to) such debt securities, and any mandatory sinking fund or analogous payments thereon, on their scheduled due dates.

     In addition, we can only elect defeasance or covenant defeasance if, among other things:

•  the defeasance or covenant defeasance does not result in a breach or violation of, or constitute a default under, the indenture or any other material agreement or instrument to which we are a party or by which we are bound;

•  no event of default or event that with notice or lapse of time or both would become an event of default with respect to the debt securities to be defeased will have occurred and be continuing on the date of the deposit of funds with the trustee and, with respect to defeasance only, at any time during the period ending on the 123rd day after the date of the deposit of funds with the trustee; and

•  we have delivered to the trustee an opinion of counsel to the effect that the holders of the debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the defeasance or covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and

28

at the same times as would have been the case if the defeasance had not occurred, and the opinion of counsel, in the case of defeasance, must refer to and be based upon a letter ruling of the Internal Revenue Service received by us, a Revenue Ruling published by the Internal Revenue Service or a change in applicable U.S. federal income tax law occurring after the date of the indenture.

     The indenture deems a foreign currency to be any currency, currency unit or composite currency including, without limitation, the euro, issued by the government of one or more countries other than the United States or by any recognized confederation or association of governments.

     The indenture defines government obligations as securities that are not callable or redeemable at the option of the issuer or issuers and are:

•  direct obligations of the United States or the government or governments in the confederation that issued the foreign currency in which the debt securities of a particular series are payable, for the payment of which its full faith and credit is pledged; or

•  obligations of a person or entity controlled or supervised by and acting as an agency or instrumentality of the United States or the government or governments that issued the foreign currency in which the debt securities of a particular series are payable, the timely payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States or that other government or governments.

     Government obligations also include a depositary receipt issued by a bank or trust company as custodian with respect to any government obligation described above or a specific payment of interest on or principal of or any other amount with respect to any government obligation held by that custodian for the account of the holder of such depositary receipt, as long as, except as required by law, that custodian is not authorized to make any deduction from the amount payable to the holder of the depositary receipt from any amount received by the custodian with respect to the government obligation or the specific payment of interest on or principal of or any other amount with respect to the government obligation evidenced by the depositary receipt.

     Unless otherwise specified in the applicable prospectus supplement, if, after we have deposited funds and/or government obligations to effect defeasance or covenant defeasance with respect to debt securities of any series, either:

•  the holder of a debt security of that series is entitled to, and does, elect to receive payment in a currency other than that in which such deposit has been made in respect of that debt security; or

•  a conversion event, as defined below, occurs in respect of the foreign currency in which the deposit has been made, the indebtedness represented by that debt security shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of, and any premium and interest on, and additional amounts, if any, with respect to, that debt security as that debt security becomes due out of the proceeds yielded by converting the amount or other properties so deposited in respect of that debt security into the currency in which that debt security becomes payable as a result of the election or conversion event based on:

29

•  in the case of payments made pursuant to the first of the two items in the list above, the applicable market exchange rate for the currency in effect on the second business day prior to the date of the payment; or

•  with respect to a conversion event, the applicable market exchange rate for such foreign currency in effect, as nearly as feasible, at the time of the conversion event.

     The indenture defines a “conversion event” as the cessation of use of:

•  a foreign currency both by the government of the country or the confederation that issued such foreign currency and for the settlement of transactions by a central bank or other public institutions of or within the international banking community; or

•  any currency unit or composite currency for the purposes for which it was established.

     Unless otherwise provided in the applicable prospectus supplement, all payments of principal of, and any premium and interest on, any debt security that are payable in a foreign currency that ceases to be used by the government or confederation of issuance shall be made in U.S. dollars.

     If we effect a covenant defeasance with respect to any debt securities and the debt securities are declared due and payable because of the occurrence of any event of default other than an event of default with respect to which there has been covenant defeasance, the amount in the foreign currency in which the debt securities are payable, and government obligations on deposit with the trustee, will be sufficient to pay amounts due on the debt securities at the time of the stated maturity but may not be sufficient to pay amounts due on the debt securities at the time of the acceleration resulting from the event of default. However, we would remain liable for payment of the amounts due at the time of acceleration.

     The applicable prospectus supplement may further describe the provisions, if any, permitting defeasance or covenant defeasance, including any modifications to the provisions described above, with respect to the debt securities of or within a particular series.

Modification and Waiver

     We and the trustee may generally modify certain provisions of the indenture with the consent of the holders of not less than a majority in aggregate principal amount of the debt securities of each series affected by the modification, except that no such modification or amendment may, without the consent of the holder of each debt security affected thereby,

•  change the stated maturity of the principal of, or any installment of principal of, or any premium or interest on, or any additional amounts with respect to, any debt security issued under the indenture;

•  reduce the principal amount of, or premium or interest on, or any additional amounts with respect to, any debt security issued under the indenture;

•  change the place of payment, coin or currency in which any debt security issued under that indenture or any premium or any interest on that debt security or any additional amounts with respect to that debt security is payable;

30

•  reduce the percentage in principal amount of the outstanding debt securities, the consent of whose holders is required under the indenture in order to take certain actions;

•  change any of our obligations to maintain an office or agency in the places and for the purposes required by the indenture;

•  if the debt securities are convertible or exchangeable, modify the conversion or exchange provision in a manner adverse to holders of that debt security;

•  in the case of a subordinated debt security, modify any of the subordination provisions in a manner adverse to holders of that debt security;

•  impair the right to institute suit for the enforcement of any payment on or after the stated maturity of any debt securities issued under that indenture or, in the case of redemption, exchange or conversion, if applicable, on or after the redemption, exchange or conversion date or, in the case of repayment at the option of any holder, if applicable, on or after the date for repayment; or

•  modify any of the above provisions or certain provisions regarding the waiver of past defaults or the waiver of certain covenants, with limited exceptions.

In addition, we and the trustee may, without the consent of any holders, modify provisions of the indenture for certain purposes, including, among other things:

•  evidencing the succession of another person to DTE Energy and the assumption by any such successor of the covenants of DTE Energy in the indenture and in the debt securities;

•  adding to the covenants of DTE Energy for the benefit of the holders of debt securities (and if such covenants are to be for the benefit of less than all series of debt securities, stating that such covenants are expressly being included solely for the benefit of such series) or surrendering any right or power herein conferred upon DTE Energy with respect to the debt securities;

•  adding any additional events of default with respect to the debt securities (and, if such event of default is applicable to less than all series of debt securities, specifying the series to which such event of default is applicable);

•  adding to or changing any provisions of the indenture to provide that bearer debt securities may be registrable, changing or eliminating any restrictions on the payment of principal of (or premium, if any) or interest on or any additional amounts with respect to bearer debt securities, permitting bearer debt securities to be issued in exchange for registered debt securities, permitting bearer debt securities to be issued in exchange for bearer debt securities of other authorized denominations or facilitating the issuance of debt securities in uncertificated form, provided that any such action shall not adversely affect the interests of the holders of the debt securities in any material respect;

•  establishing the form or terms of debt securities of any series;

•  evidencing and providing for the acceptance of appointment of a successor trustee and adding to or changing any of the provisions of the indenture to facilitate the administration of the trusts;

31

•  curing any ambiguity, correcting or supplementing any provision in the indenture that may be defective or inconsistent with any other provision therein, or making or amending any other provisions with respect to matters or questions arising under the indenture which shall not adversely affect the interests of the holders of debt securities of any series in any material respect;

•  modifying, eliminating or adding to the provisions of the indenture to maintain the qualification of the indenture under the Trust Indenture Act as the same may be amended from time to time;

•  adding to, deleting from or revising the conditions, limitations and restrictions on the authorized amount, terms or purposes of issue, authentication and delivery of debt securities, as therein set forth;

•  modifying, eliminating or adding to the provisions of any security to allow for such security to be held in certificated form;

•  securing the debt securities;

•  making provisions with respect to conversion or exchange rights of holders of securities of any series;

•  amending or supplementing any provision contained therein or in any supplemental indenture, provided that no such amendment or supplement will adversely affect the interests of the holders of any debt securities then outstanding in any material respect; or

•  modifying, deleting or adding to any of the provisions of the indenture other than as contemplated above.

     The holders of at least 66 2/3% in aggregate principal amount of debt securities of any series issued under the indenture may, on behalf of the holders of all debt securities of that series, waive our compliance with certain restrictive provisions of the indenture. The holders of not less than a majority in aggregate principal amount of debt securities of any series issued under the indenture may, on behalf of all holders of debt securities of that series, waive any past default and its consequences under the indenture with respect to the debt securities of that series, except:

•  a payment default with respect to debt securities of that series; or

•  a default of a covenant or provision of the indenture that cannot be modified or amended without the consent of the holder of each debt security of that series.

Enforcement of Certain Rights by Holders of Trust Preferred Securities

     The following applies only in the event that debt securities are held by a DTE Energy Trust.

     To the extent that any action under any debt securities held by a DTE Energy Trust is entitled to be taken by the holders of at least a specified percentage of those debt securities, and unless otherwise specified in the applicable prospectus supplement, holders of the trust preferred securities issued by that DTE Energy Trust may take action if the action is not taken by the property trustee of that DTE Energy Trust. Notwithstanding the

32

foregoing, if an event of default under those debt securities has occurred and is continuing and is attributable either to:

•  the failure of DTE Energy to pay the principal of, or any premium or interest on, those debt securities on the due date; or

•  the failure by DTE Energy to deliver the required securities or other property upon an appropriate conversion or exchange election, if any,

and an event of default has occurred and is continuing under the applicable trust agreement, a holder of the related trust preferred securities may institute a direct action.

     A “direct action” is a legal proceeding directly against DTE Energy for enforcement of payment to the holder of trust preferred securities issued by a DTE Energy Trust of the principal of or any premium or interest on the debt securities held by that trust having a principal amount equal to the liquidation amount of those trust preferred securities held by that holder or for enforcement of any conversion or exchange rights, as the case may be. DTE Energy may not amend an indenture to remove this right to bring a direct action without the prior written consent of the holders of all of the trust preferred securities outstanding that have an interest in the related debt securities. If the right to bring a direct action is removed, the DTE Energy Trusts may become subject to the reporting obligations under the Securities Exchange Act. Notwithstanding any payments made to a holder of trust preferred securities by DTE Energy in connection with a direct action, DTE Energy will remain obligated to pay the principal of, and any premium and interest on, the related debt securities, and DTE Energy will be subrogated to the rights of the holders of those trust preferred securities with respect to payments on the trust preferred securities to the extent of any payments made by DTE Energy to the holder in any direct action.

     The holders of the trust preferred securities will not be able to exercise directly any remedies, other than those set forth in the preceding paragraph, available to the holders of the related debt securities unless an event of default has occurred and is continuing under the applicable trust agreement. See “Description of Trust Preferred Securities — Events of Default; Notice” below.

Resignation and Removal of the Trustee; Deemed Resignation

     The trustee may resign at any time with respect to the debt securities of one or more series by giving written notice thereof to us.

     The trustee may also be removed with respect to the debt securities of any series by act of the holders of a majority in principal amount of the then outstanding debt securities of such series.

     No resignation or removal of such trustee and not appointment of a successor trustee will become effective until the acceptance of appointment by a successor trustee in accordance with the requirements of the indenture.

     Under certain circumstances, we may appoint a successor trustee and if the successor accepts, the retiring trustee will be deemed to have resigned.

33

Governing Law

     The indenture will be governed by, and construed in accordance with, the laws of the State of New York.

Concerning the Trustees

     The Bank of New York is the trustee under the indenture. In addition to acting as trustee, The Bank of New York, as described in this prospectus, also acts as property trustee under the trust agreement and the guarantee trustee under the guarantee; The Bank of New York (Delaware) acts as the Delaware trustee under the trust agreement. The Bank of New York also acts as trustee with respect to the securitization bonds issued by The Detroit Edison Securitization Funding LLC and may act as trustee under various other indentures, trusts and guarantees of DTE Energy and its affiliates and perform other banking, trust and investment banking services for DTE Energy and its affiliates in the ordinary course of business.

     The Trust Indenture Act contains limitations on the rights of the trustee, should it become a creditor of DTE Energy, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of any such claims, as security or otherwise. The trustee is permitted to engage in other transactions with DTE Energy and its subsidiaries from time to time, provided that if the trustee acquires any conflicting interest it must eliminate such conflict upon the occurrence of an event of default under the indenture, or else resign.

Description of Common Stock Purchase Contracts and Units

      We may issue stock purchase contracts, representing contracts entitling or obligating holders to purchase from DTE Energy, and DTE Energy to sell to the holders, a specified number of shares of common stock at a future date or dates. The price per share of common stock may be fixed at the time the contracts are issued or may be determined by reference to a specific formula set forth in the contracts. The common stock purchase contracts may be issued separately or as a part of units, which are referred to in this prospectus as “common stock purchase units,” consisting of a common stock purchase contract and, as security for the holder’s obligations to purchase the common stock under the contracts, the following:

•  senior debt securities or subordinated debt securities of DTE Energy;

•  debt obligations of third parties, including U.S. Treasury securities;

•  trust preferred securities of a DTE Energy Trust;

•  any other security described in the applicable prospectus supplement; or

•  any combination of the foregoing.

     The common stock purchase contracts may require us to make periodic payments to the holders of the common stock purchase units or vice versa, and such payments may be unsecured or prefunded on some basis. The common stock purchase contracts may require holders to secure their obligations thereunder in a specified manner, and in certain circumstances we may deliver newly issued prepaid common stock purchase contracts,

34

which are referred to as “prepaid securities,” upon release to a holder of any collateral securing such holder’s obligations under the original contract.

     The applicable prospectus supplement will describe the terms of any common stock purchase contracts or units and, if applicable, prepaid securities. The description in the prospectus supplement will not purport to be complete and will be qualified in its entirety by reference to the contracts, the collateral arrangements and depositary arrangements, if applicable, relating to such contracts or units and, if applicable, the prepaid securities and the document pursuant to which such prepaid securities will be issued.

Description of Trust Preferred Securities

      Each DTE Energy Trust will issue under its trust agreement only one series of trust preferred securities, that will represent beneficial interests in that DTE Energy Trust. Each DTE Energy Trust will qualify its trust agreement under the Trust Indenture Act. Each trust agreement is subject to, and governed by, the Trust Indenture Act. This summary of certain terms and provisions of the trust preferred securities and the trust agreement does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all of the provisions of the trust preferred securities and the trust agreement, including the definitions of certain terms, and those made a part of the trust agreement by the Trust Indenture Act. A form of trust agreement, including a form of trust securities, is filed as an exhibit to the registration statement that includes this prospectus. If indicated in the applicable prospectus supplement, the terms of a DTE Energy Trust may differ from the terms summarized below.

General

     The trust preferred securities of each DTE Energy Trust will rank equally, and payments will be made on the trust preferred securities proportionately, with the trust common securities of each DTE Energy Trust except as described under “— Subordination of Trust Common Securities.” Each DTE Energy Trust will use the proceeds from the sale of trust preferred securities and trust common securities to purchase an aggregate principal amount of debt securities of DTE Energy equal to the aggregate liquidation amount of those trust preferred securities and trust common securities. The property trustee of each DTE Energy Trust will hold legal title to the debt securities for the benefit of the holders of the related trust securities. In addition, DTE Energy will execute a guarantee for the benefit of the holders of the related trust preferred securities. The guarantees will not guarantee payment of distributions or amounts payable or securities or other property deliverable, if any, on redemption, repayment, conversion or exchange of the trust preferred securities or liquidation of a DTE Energy Trust when the trust does not have funds or other property legally available for payment or delivery. See “Description of Trust Preferred Securities Guarantees.”

     The revenue of a DTE Energy Trust available for distribution to holders of its trust preferred securities will be limited to payments under the related debt securities and any other assets held by that DTE Energy Trust. If DTE Energy fails to make a required payment in respect of those debt securities or any other assets, that DTE Energy Trust will not have sufficient funds to make the related payments, including distributions, in respect of its trust preferred securities.

35

     Each DTE Energy Trust will describe the specific terms of the trust preferred securities it is offering in the applicable prospectus supplement, including:

•  the designation, number, purchase price and liquidation amount, if any, of the trust preferred securities;

•  the distribution rate, or method of calculation of the distribution rate, for the trust preferred securities and, if applicable, any deferral provisions;

•  whether the distributions on the trust preferred securities will be cumulative and, if so, the dates from which and upon which distributions will accumulate and be payable and the record dates;

•  if other than U.S. dollars, the currency in which cash payments are payable;

•  the liquidation amount per trust preferred security that will be paid out of the assets of that DTE Energy Trust to the holders upon voluntary or involuntary dissolution and liquidation of that trust;

•  the obligation or right, if any, of that DTE Energy Trust to purchase or redeem its trust preferred securities, whether pursuant to a sinking fund or otherwise, and the price or prices at which, the date or dates on which or period or periods within which and the terms and conditions upon which, it will or may purchase or redeem, in whole or in part, the trust preferred securities pursuant to its obligation or right to purchase or redeem;

•  the terms and conditions, if any, upon which the trust preferred securities may be converted or exchanged, in addition to the circumstances described herein, into other securities or property, or a combination of the foregoing;

•  the obligation or right, if any, of DTE Energy, that DTE Energy Trust or any other party to liquidate that DTE Energy Trust and any terms and conditions of such liquidation;

•  the voting rights, if any, of the holders;

•  if applicable, any securities exchange upon which the trust preferred securities will be listed;

•  if applicable, a description of any remarketing, auction or other similar arrangements;

•  whether the trust preferred securities are issuable in book-entry only form and, if so, the identity of the depositary and disclosure relating to the depositary arrangements; and

•  any other rights, preferences, privileges, limitations or restrictions of the trust preferred securities consistent with the trust agreement or with applicable law, which may differ from those described herein.

     Each DTE Energy Trust will also describe certain material United States federal income tax considerations applicable to any offering of trust preferred securities in the applicable prospectus supplement.

36

Subordination of Trust Common Securities

     Each DTE Energy Trust will pay distributions on, and the applicable redemption price of, and any other amounts payable or property deliverable under, the trust securities it issues equally among its trust preferred securities and its trust common securities based on their respective liquidation amounts. But, if on any distribution date, redemption date, repayment date or conversion or exchange date, or upon liquidation or an event of default under the debt securities held by that DTE Energy Trust or any other event of default under the trust agreement has occurred and is continuing, that DTE Energy Trust will not pay any distribution on, or applicable redemption or repayment price of, or convert or exchange any of its trust common securities. Further, it will not make any other payment on account of the redemption, repayment, conversion, exchange, liquidation or other acquisition of the trust common securities, unless payment in full in cash of all accumulated distributions on all of the outstanding trust preferred securities of that DTE Energy Trust for all distribution periods terminating on or before the redemption, repayment, conversion, exchange, liquidation or other acquisition, and, in the case of payment of the applicable redemption or repayment price, the full amount of the redemption or repayment price, will have been made or provided for. And, in the case of conversion or exchange, no such payments will be made unless the trust preferred securities have been converted or exchanged in full and other amounts payable have been paid. The property trustee will apply all available funds first to the payment in full in cash of all distributions on, or the applicable redemption price of, the trust preferred securities issued by that DTE Energy Trust then due and payable.

     Until any event of default under the trust agreement for a DTE Energy Trust has been cured, waived or otherwise eliminated, the property trustee will act solely on behalf of the holders of the trust preferred securities of that DTE Energy Trust and not on behalf of DTE Energy as the direct or indirect trust common securities owner, and only the holders of the trust preferred securities issued by that DTE Energy Trust will have the right to direct the property trustee to act on their behalf.

Events of Default; Notice

     The occurrence of an event of default under the debt securities held by a DTE Energy Trust will constitute an event of default under the trust agreement for that DTE Energy Trust. Within 90 days after the occurrence of an event of default actually known to the property trustee, the property trustee will transmit notice of that event of default to the holders of the trust preferred securities of that DTE Energy Trust, the administrative trustees and DTE Energy, as sponsor, unless the event of default shall have been cured or waived.

     For a discussion of the limited circumstances in which holders of trust preferred securities may bring a direct action against DTE Energy under the debt securities, see “Description of Debt Securities — Enforcement of Certain Rights by Holders of Trust Preferred Securities.” The applicable prospectus supplement may describe additional events of default under the trust agreement.

Removal of Trustees

     Unless an event of default under the debt securities held by a DTE Energy Trust has occurred and is continuing, DTE Energy, as the direct or indirect owner of trust common securities of that DTE Energy Trust, may remove the property trustee, the Delaware

37

trustee and the administrative trustees at any time. If an event of default under the debt securities held by a DTE Energy Trust has occurred and is continuing, only the holders of a majority in liquidation amount of the outstanding trust preferred securities of that DTE Energy Trust may remove and replace the property trustee and the Delaware trustee for that DTE Energy Trust. In no event will the holders of the trust preferred securities have the right to vote to appoint, remove or replace the administrative trustees, which voting rights are vested exclusively in DTE Energy as the direct or indirect trust common securities owner. No resignation or removal of a property or Delaware trustee, and no appointment of a successor to that trustee, will be effective until the acceptance of appointment by the successor trustee in accordance with the provisions of the applicable trust agreement.

Merger or Consolidation of Property or Delaware Trustees

     Any person into which the property trustee or the Delaware trustee may be merged or converted or with which it may be consolidated, or any person resulting from any merger, conversion or consolidation to which the property trustee or the Delaware trustee will be a party, or any person succeeding to all or substantially all the corporate trust business of the property trustee or the Delaware trustee, will be the successor of the property trustee or the Delaware trustee under the trust agreement, provided that the person will be otherwise qualified and eligible.

Mergers, Conversions, Consolidations, Amalgamations or Replacements of a DTE Energy Trust

     A DTE Energy Trust may not merge with or into, convert into, consolidate, amalgamate, or be replaced by, or convey, transfer or lease its properties and assets as an entirety or substantially as an entirety, to any other person, except as described below or as otherwise described in the applicable prospectus supplement. A DTE Energy Trust may, at the request of DTE Energy, as sponsor, with the consent of the administrative trustees but without the consent of the holders of its trust preferred securities, the Delaware trustee or the property trustee, merge with or into, convert into, consolidate, amalgamate, or be replaced by a trust organized as such under the laws of any state of the United States; provided, that:

•  the successor entity expressly assumes all of the obligations of that DTE Energy Trust under any agreement to which the trust is a party and either:

•  expressly assumes all of the obligations of that DTE Energy Trust with respect to the trust securities of that DTE Energy Trust, or

•  substitutes for the trust securities of that DTE Energy Trust other securities having substantially the same terms as those trust securities, so long as the successor trust securities rank the same as the trust securities rank with respect to distributions and payments upon liquidation, redemption and otherwise;

•  DTE Energy expressly appoints a trustee of the successor entity possessing substantially the same powers and duties as the property trustee with respect to the debt securities held by that DTE Energy Trust;

•  the successor securities are listed, or any successor securities will be listed upon notification of issuance, if applicable, on each national securities exchange or other

38

	organization on which the trust securities of that DTE Energy Trust are then listed, if any;
•	the merger, conversion, consolidation, amalgamation or replacement does not cause the trust securities, including any successor securities, of that DTE Energy Trust to be downgraded or placed under surveillance or review by any nationally recognized statistical rating organization;
•	the merger, conversion, consolidation, amalgamation or replacement does not adversely affect the rights, preferences and privileges of the holders of the trust securities, including any successor securities, of that DTE Energy Trust in any material respect;
•	the successor entity has a purpose substantially identical to that of that DTE Energy Trust;
•	prior to the merger, conversion, consolidation, amalgamation or replacement, DTE Energy has received an opinion from a nationally recognized independent counsel experienced in these matters and representing that DTE Energy Trust, to the effect that:

•  the merger, conversion, consolidation, amalgamation or replacement does not adversely affect the rights, preferences and privileges of the holders of the trust securities, including any successor securities, of that DTE Energy Trust in any material respect,

•  following the merger, conversion, consolidation, amalgamation or replacement, neither that DTE Energy Trust nor the successor entity, if any, will be required to register as an investment company under the Investment Company Act of 1940, as amended, and

•  following the merger, conversion, consolidation, amalgamation or replacement, that DTE Energy Trust or the successor entity, as the case may be, will continue to be classified as a grantor trust for United States federal income tax purposes;

•  DTE Energy or any permitted successor or assignee directly or indirectly owns all of the common securities of the successor entity and guarantees the obligations of the successor entity under the successor securities at least to the extent provided by the applicable guarantee; and

•  the property trustee has received an officer’s certificate of DTE Energy and an opinion of counsel, each to the effect that all conditions precedent to the transaction as set forth in the trust agreement have been satisfied.

     Despite the foregoing, a DTE Energy Trust may, with the consent of holders of 100% in liquidation amount of the trust securities, consolidate, amalgamate, merge with or into, or be replaced by any other entity or permit any other entity to consolidate, amalgamate, merge with or into, or replace it, if the consolidation, amalgamation, merger or replacement would cause the DTE Energy Trust or the successor entity to be classified as other than a grantor trust for United States federal income tax purposes.

39

Voting Rights; Amendment of Trust Agreement

     Except as provided under “— Mergers, Conversions, Consolidations, Amalgamations or Replacements of a DTE Energy Trust” and “Description of Trust Preferred Securities Guarantees — Amendments and Assignment” and as otherwise required by law and the trust agreement or specified in the applicable prospectus supplement, the holders of trust preferred securities will have no voting rights.

     DTE Energy, the property trustee, the Delaware trustee and the administrative trustees may amend from time to time the trust agreement for a DTE Energy Trust, without the consent of the holders of the trust securities of that DTE Energy Trust,

•  to cure any ambiguity, or correct or supplement any provisions in the trust agreement that may be defective or inconsistent with any other provision,

•  to add to the covenants, restrictions or obligations of the sponsor,

•  to conform to any change in the Investment Company Act or Trust Indenture Act or the rules promulgated thereunder, or any written change in interpretation of such acts or rules by any governmental authority, or

•  to cause that DTE Energy Trust to continue to be classified for United States federal income tax purposes as a grantor trust;

provided, however, that any such modification that will adversely affect the rights of the holders of the trust securities issued by that DTE Energy Trust requires the consent of the holders of a majority in liquidation amount of each class of trust securities affected.

     Without the consent of each holder of trust securities issued by a DTE Energy Trust, the trust agreement for that DTE Energy Trust may not be amended to:

•  change the distribution rate, or manner of calculation of the distribution rate, amount, timing or currency or otherwise adversely affect the method of any required payment;

•  change its purpose;

•  authorize the issuance of any additional beneficial interests;

•  change the conversion, exchange or redemption provisions, if any;

•  change the conditions precedent for DTE Energy to elect to dissolve that DTE Energy Trust and distribute the debt securities held by that DTE Energy Trust to the holders of the trust securities, if applicable;

•  change the liquidation, distribution or other provisions relating to the distribution of amounts payable upon the dissolution and liquidation of that DTE Energy Trust;

•  affect the limited liability of any holder of its trust securities; or

•  restrict the right of a holder of its trust securities to institute suit for the enforcement of any required distribution on or, if applicable, after the due date therefor or for the conversion or exchange of the trust securities in accordance with their terms.

40

     So long as the property trustee holds any debt securities for a DTE Energy Trust, the property trustee, the Delaware trustee and the administrative trustees for that DTE Energy Trust will not:

•  direct the time, method and place of conducting any proceeding for any remedy available to the debt securities trustee, or execute any trust or power conferred on the property trustee, with respect to those debt securities;

•  waive certain past defaults under the indenture;

•  exercise any right to rescind or annul a declaration of acceleration of the maturity of the principal of those debt securities; or

•  consent to any amendment, modification or termination of the indenture or those debt securities, where consent is required;

without, in each case, obtaining the prior approval of the holders of a majority in liquidation amount of all outstanding trust preferred securities of that DTE Energy Trust. But, where a consent under the indenture would require the consent of each holder of those debt securities affected thereby, the property trustee will not consent without the prior approval of each holder of the trust preferred securities issued by that DTE Energy Trust. The property trustee, the Delaware trustee and the administrative trustees may not revoke any action previously authorized or approved by a vote of the holders of trust preferred securities except by subsequent vote of the holders. The property trustee will notify each holder of trust preferred securities of any notice of default with respect to the applicable debt securities. In addition to obtaining approvals of holders of trust preferred securities referred to above, prior to taking any of the foregoing actions (other than directing the time, method and place of conducting any proceeding for any remedy available to the debt securities trustee), the property trustee will obtain an opinion of counsel experienced in these matters to the effect that the applicable DTE Energy Trust will not be classified as other than a grantor trust for United States federal income tax purposes on account of such action.

     Any required approval of holders of trust preferred securities may be given at a meeting of the holders convened for this purpose or by written consent without prior notice. The property trustee will cause a notice of any meeting at which holders of trust preferred securities are entitled to vote to be given to each holder of record of trust preferred securities in the manner set forth in the trust agreement.

     Notwithstanding that holders of trust preferred securities are entitled to vote or consent under any of the circumstances referred to above, any trust preferred securities that are owned by DTE Energy or any affiliate of DTE Energy will, for purposes of this vote or consent, be treated as if they were not outstanding.

Global Trust Preferred Securities

     Unless otherwise specified in the applicable prospectus supplement, trust preferred securities will be represented by one or more global certificates deposited with, or on behalf of, DTC, or such other depository identified in the prospectus supplement, or a nominee of DTC or other depository, in each case for credit to an account of a participant in DTC or other depository. See “Book-Entry Securities.”

41

Payment and Paying Agent

     Payments in respect of any global certificate representing trust preferred securities will be made to Cede & Co. as nominee of DTC or other applicable depository or its nominee, which will credit the relevant accounts at DTC or other depository on the applicable payment dates, while payments in respect of trust preferred securities in certificated form will be made by check mailed to the address of the holder entitled thereto as the address will appear on the register. The paying agent will initially be the property trustee and any co-paying agent chosen by the property trustee and acceptable to the administrative trustees and DTE Energy. The paying agent will be permitted to resign as paying agent upon 30 days prior written notice to the property trustee, the administrative trustees and DTE Energy. In the event that the property trustee will no longer be the paying agent, the administrative trustees will appoint a successor, which will be a bank or trust company acceptable to the administrative trustees and DTE Energy, to act as paying agent.

Registrar and Transfer Agent

     The property trustee will act as registrar and transfer agent for the trust preferred securities.

     Registration of transfers of trust preferred securities will be effected without charge by or on behalf of a DTE Energy Trust, upon payment of any tax or other governmental charges that may be imposed in connection with any transfer or exchange. A DTE Energy Trust will not be required to register or cause to be registered the transfer of its trust preferred securities after they have been converted, exchanged, redeemed, repaid or called for redemption or repayment.

Information Concerning the Property Trustee

     The property trustee, other than during the occurrence and continuance of an event of default under the trust agreement, will undertake to perform only the duties that are specifically set forth in the trust agreement and, during the continuance of that event of default, must exercise the same degree of care and skill as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to the foregoing, the property trustee will not be under any obligation to exercise any of the powers vested in it by the trust agreement at the request of any holder of the related trust securities unless the holder offers the property trustee reasonable indemnity against the costs, expenses and liabilities that it might incur thereby.

Miscellaneous

     The administrative trustees are authorized and directed to conduct the affairs of and to operate each DTE Energy Trust in such a way that:

•  that DTE Energy Trust will not be deemed to be an investment company required to be registered under the Investment Company Act;

•  that DTE Energy Trust will be classified as a grantor trust for United States federal income tax purposes; and

•  the debt securities held by that DTE Energy Trust will be treated as indebtedness of DTE Energy for United States federal income tax purposes.

42

     DTE Energy and the administrative trustees are authorized to take any action, not inconsistent with applicable law, the certificate of trust of each DTE Energy Trust or each trust agreement, that the administrative trustees determine in their discretion to be necessary or desirable for those purposes, as long as that action does not materially adversely affect the interests of the holders of the related trust securities.

     Holders of trust preferred securities will not have any preemptive or similar rights.

Accounting Treatment

     Each DTE Energy Trust will be treated as a subsidiary of ours for financial reporting purposes. Accordingly, our consolidated financial statements will include the accounts of each trust. The trust preferred securities for each DTE Energy Trust, along with other trust preferred securities that we guarantee on an equivalent basis, will be presented as a separate line item in our consolidated balance sheets, and appropriate disclosures about the trust preferred securities, the applicable guarantee and the debt securities will be included in the notes to the consolidated financial statements. We will record distributions that each DTE Energy Trust pays on its trust preferred securities as an expense in our consolidated statement of income.

Description of Trust Preferred Securities Guarantees

      DTE Energy will execute and deliver a guarantee concurrently with the issuance by a DTE Energy Trust of its trust preferred securities for the benefit of the holders from time to time of those trust preferred securities. That guarantee will be held for those holders by a guarantee trustee. DTE Energy will qualify each of the guarantees as an indenture under the Trust Indenture Act. The guarantees will be subject to, and governed by, the Trust Indenture Act. This summary of certain terms and provisions of a guarantee does not purport to be complete and is subject to, and qualified in its entirety by reference to, all of the provisions of each guarantee, including the definitions of terms, and those made a part of each guarantee by the Trust Indenture Act. A form of guarantee is filed as an exhibit to the registration statement that includes this prospectus. If indicated in the applicable prospectus supplement, the terms of a particular guarantee may differ from the terms discussed below.

General

     Pursuant to and to the extent set forth in the guarantee, DTE Energy will irrevocably and unconditionally agree to pay in full the guarantee payments to the holders of the related trust preferred securities, as and when due, regardless of any defense, right of set-off or counterclaim that a DTE Energy Trust may have or assert. The following payments constitute guarantee payments with respect to trust preferred securities and, to the extent not paid by or on behalf of a DTE Energy Trust, will be subject to the applicable guarantee:

•  any accumulated and unpaid distributions that are required to be paid on the applicable trust preferred securities, to the extent that a DTE Energy Trust has funds legally available therefor at such time;

•  the applicable redemption or repayment price and all accumulated and unpaid distributions to the date of redemption or repayment with respect to the trust

43

	preferred securities called for redemption or repayment, to the extent that a DTE Energy Trust has funds legally available therefor at such time; or
•	upon a voluntary or involuntary dissolution and liquidation of the applicable DTE Energy Trust, other than in connection with the distribution of the debt securities to holders of its trust preferred securities or the redemption, repayment, conversion or exchange of its trust preferred securities, if applicable, the lesser of:

•  the aggregate of the liquidation amount and all accrued and unpaid distributions on the trust preferred securities to the date of payment, to the extent the DTE Energy Trust has funds available therefor, and

•  the amount of assets of that DTE Energy Trust remaining available for distribution to holders of its trust preferred securities in liquidation of that DTE Energy Trust.

     DTE Energy’s obligation to make a guarantee payment may be satisfied by direct payment of the required amounts by DTE Energy to the holders of the applicable trust preferred securities entitled to those payments or by causing the applicable DTE Energy Trust to pay those amounts to the holders.

     If the trust preferred securities are exchangeable or convertible into other securities, DTE Energy will also irrevocably agree to cause the applicable DTE Energy Trust to deliver to holders of those trust preferred securities those other securities in accordance with the applicable exchange or conversion provisions.

     DTE Energy will, through the guarantee, the applicable trust agreement, the related debt securities and the applicable indenture, taken together, fully, irrevocably and unconditionally guarantee all of each DTE Energy Trust’s obligations under its trust preferred securities. No single document standing alone or operating in conjunction with fewer than all of the other documents constitutes a guarantee. It is only the combined operation of these documents that has the effect of providing a full, irrevocable and unconditional guarantee of each DTE Energy Trust’s obligations under its trust preferred securities.

Ranking

     Unless otherwise specified in the applicable prospectus supplement, each guarantee will constitute an unsecured obligation of DTE Energy and will rank equal to the debt securities held by the DTE Energy Trust that issued the trust preferred securities covered by the guarantee and senior to DTE Energy common stock. Each trust agreement provides that each holder of trust preferred securities, by acceptance of the applicable trust preferred securities, agrees to the terms of the related guarantee, including any subordination provisions.

     The guarantees will not limit the amount of secured or unsecured debt, including indebtedness under the indenture, that may be incurred by DTE Energy or any of its subsidiaries.

Guarantee of Payment

     Each guarantee will constitute a guarantee of payment and not of collection. This means that the guaranteed party may institute a legal proceeding directly against DTE

44

Energy to enforce its rights under a guarantee without first instituting a legal proceeding against any other person or entity. A guarantee will not be discharged except by payment of the related guarantee payments in full to the extent not paid by the applicable DTE Energy Trust or upon distribution of the debt securities or other assets held by the DTE Energy Trust to the holders of the its trust preferred securities.

Amendments and Assignment

     Except with respect to any changes that do not materially adversely affect the rights of holders of the related trust preferred securities, in which case no approval will be required, a guarantee may not be amended without the prior approval of the holders of a majority of the liquidation amount of the outstanding trust preferred securities covered by that guarantee. The manner of obtaining any approval will be as set forth under “Description of Trust Preferred Securities — Voting Rights; Amendment of a Trust Agreement.” All guarantees and agreements contained in a guarantee will bind the successors, assigns, receivers, trustees and representatives of DTE Energy and will inure to the benefit of the holders of the related trust preferred securities then outstanding.

Events of Default

     An event of default under a guarantee will occur upon the failure of DTE Energy to perform any of its payment or other obligations under that guarantee, provided that, except with respect to a default in respect of any guarantee payment or delivery of any securities upon conversion or exchange of the trust securities, DTE Energy has not cured the default 90 days from the date the guarantee trustee obtains knowledge of the event of default. The holders of a majority in liquidation amount of the trust preferred securities covered by a guarantee will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the guarantee trustee in respect of that guarantee or to direct the exercise of any trust or power conferred upon the guarantee trustee under that guarantee.

     If the guarantee trustee fails to enforce a guarantee, any holder of the related trust preferred securities may institute a legal proceeding directly against DTE Energy to enforce its rights under that guarantee without first instituting a legal proceeding against the applicable DTE Energy Trust, the guarantee trustee or any other person or entity.

Termination

     A guarantee will terminate and be of no further force and effect upon full payment of the applicable redemption or repayment price of the related trust preferred securities, upon full payment of all amounts or delivery of all securities or other property due upon the dissolution and liquidation of the applicable DTE Energy Trust or upon the conversion or exchange of all of the related trust preferred securities. A guarantee will continue to be effective or will be reinstated, as the case may be, if at any time any holder of the related trust preferred securities must restore payment of any sums paid or other property distributed under those trust preferred securities or the related guarantee.

Information Concerning the Guarantee Trustee

     The Bank of New York will be the guarantee trustee under the guarantees.

45

     The guarantee trustee, other than during the occurrence and continuance of a default by DTE Energy in performance of a guarantee, will undertake to perform only the duties that are specifically set forth in that guarantee and, during the continuance of that default, must exercise the same degree of care and skill as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to the foregoing, the guarantee trustee will not be under any obligation to exercise any of the powers vested in it by a guarantee at the request of any holder of the related trust preferred securities unless it is offered reasonable indemnity against the costs, expenses and liabilities that it might incur.

Rights Upon Dissolution

     Unless the debt securities held by a DTE Energy Trust are distributed to holders of the related trust preferred securities, upon any voluntary or involuntary dissolution and liquidation of that DTE Energy Trust, after satisfaction of the liabilities of its creditors as required by applicable law, the holders of those trust preferred securities will be entitled to receive, out of assets held by that DTE Energy Trust, the liquidation distribution in cash. Upon any voluntary or involuntary liquidation or bankruptcy of DTE Energy, the property trustee, as holder of the debt securities, would be a creditor of DTE Energy.

Book-Entry Securities

      Unless we otherwise specify in the applicable prospectus supplement, we will issue to investors securities, other than our common stock, in the form of one or more book-entry certificates registered in the name of a depository or a nominee of a depository. Unless we otherwise specify in the applicable prospectus supplement, the depository will be DTC. We have been informed by DTC that its nominee will be Cede & Co. Accordingly, we expect Cede & Co. to be the initial registered holder of all securities that are issued in book-entry form.

     No person that acquires a beneficial interest in securities issued in book-entry form will be entitled to receive a certificate representing those securities, except as set forth in this prospectus or in the applicable prospectus supplement. Unless and until definitive securities are issued under the limited circumstances described below, all references to actions by holders or beneficial owners of securities issued in book-entry form will refer to actions taken by DTC upon instructions from its participants, and all references to payments and notices to holders or beneficial owners will refer to payments and notices to DTC or Cede & Co., as the registered holder of such securities.

     DTC has informed us that it is:

•  a limited-purpose trust company organized under New York banking laws;

•  a “banking organization” within the meaning of the New York banking laws;

•  a member of the Federal Reserve System;

•  a “clearing corporation” within the meaning of the New York Uniform Commercial Code; and

•  a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act.

46

     DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation, which we refer to as DTCC. DTCC, in turn, is owned by a number of direct participants of DTC and members of the National Securities Clearing Corporation, Government Securities Clearing Corporation, MBS Clearing Corporation and Emerging Markets Clearing Corporation, also subsidiaries of DTCC, as well as by the New York Stock Exchange, Inc., the American Stock Exchange LLC and the National Association of Securities Dealers, Inc.

     DTC has also informed us that it:

•  holds securities for “participants”; and

•  facilitates the computerized settlement of securities transactions among participants through computerized electronic book-entry changes in participants’ accounts, thereby eliminating the need for the physical movement of securities certificates.

     Participants have accounts with DTC and include securities brokers and dealers, banks, trust companies and clearing corporations. Indirect access to the DTC system also is available to indirect participants such as banks, brokers, dealers, trust companies and clearing corporations that clear through or maintain a custodial relationship with a participant, either directly or indirectly. Persons that are not participants or indirect participants but desire to buy, sell or otherwise transfer ownership of or interests in securities may do so only through participants and indirect participants. The DTC Rules applicable to its participants are on file with the SEC.

     Purchases of securities under the DTC system must be made by or through participants, which will receive a credit for the securities on DTC’s records. The ownership interest of each actual purchaser of each security (“Beneficial Owner”) is in turn to be recorded on the participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the securities are to be accomplished by entries made on the books of participants acting on behalf of Beneficial Owners.

     To facilitate subsequent transfers, all securities deposited by participants with DTC are registered in the name of Cede & Co., or such other name as may be requested by DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the securities; DTC’s records reflect only the identity of the participants to whose accounts securities are credited. The participants will remain responsible for keeping account of their holdings on behalf of their customers.

     Conveyance of notices and other communications by DTC to participants and by participants to Beneficial Owners will be governed by arrangements among them subject to any statutory or regulatory requirements as may be in effect from time to time.

     Redemption notices will be sent to DTC. If less than all of the securities within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in such issue to be redeemed.

47

     Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to securities unless authorized by a participant in accordance with DTC’s procedures. Under its usual procedures, DTC mails an Omnibus Proxy to us as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts securities are credited on the record date (identified in a listing attached to the Omnibus Proxy.)

     Payments on the securities will be made to Cede & Co., or such other nominee as may be requested by DTC. DTC’s practice is to credit participants’ accounts upon DTC’s receipt of funds and corresponding detail information, on payable date in accordance with their respective holdings shown on DTC’s records. Payments by participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such participant and not of DTC nor its nominee, DTE Energy, the DTE Energy Trusts, or the trustees subject to any statutory or regulatory requirements as may be in effect from time to time. Distributions and payments to Cede & Co. (or such other nominee) is the responsibility of DTE Energy, the DTE Energy Trusts, or the trustee, disbursement of such payments to participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of participants.

     Unless otherwise specified in the applicable prospectus supplement, a book-entry security will be exchangeable for definitive securities registered in the names of the persons other than DTC or its nominee only if:

•  DTC notifies us that it is unwilling or unable to continue as depository for the book-entry security or DTC ceases to be a clearing agency registered under the Securities Exchange Act at a time when DTC is required to be so registered; or

•  we execute and deliver to the trustee an order complying with the requirements of the indenture that the book-entry security will be so exchangeable; or

•  an event of default has occurred and is continuing.

     Any book-entry security that is exchangeable in accordance with the preceding sentence will be exchangeable for securities registered in such names as DTC directs.

     If one of the events described in the immediately preceding paragraph occurs, DTC is generally required to notify all participants of the availability through DTC of definitive securities. Upon surrender by DTC of the book-entry security representing the securities and delivery of instructions for re-registration, the trustee will reissue the securities as definitive securities. After reissuance of the securities, such persons will recognize the beneficial owners of such definitive securities as registered holders of securities.

     Except as described above:

•  a book-entry security may not be transferred except as a whole book-entry security by or among DTC, a nominee of DTC and/or a successor depository appointed by us; and

•  DTC may not sell, assign or otherwise transfer any beneficial interest in a book-entry security unless the beneficial interest is in an amount equal to an authorized denomination for the securities evidenced by the book-entry security.

48

     DTC may discontinue providing its services as depository with respect to the securities at any time by giving reasonable notice to us or the trustee. Under such circumstances, in the event that a successor depository is not obtained, security certificates are required to be printed and delivered.

     We may decide to discontinue use of the system of book-entry transfers through DTC (or a successor securities depository). In that event, security certificates will be printed and delivered.

     The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.

     None of DTE Energy, the DTE Energy Trusts, the trustees or any registrar and transfer agent, any underwriter, agent or dealer or any agent of any of them, will have any responsibility or liability for any aspect of DTC’s or any participant’s records relating to, or for payments made on account of, beneficial interests in a book-entry security.

Plan of Distribution

      DTE Energy and the DTE Energy Trusts may sell the securities through agents, underwriters or dealers, or directly to one or more purchasers without using underwriters or agents.

     DTE Energy and the DTE Energy Trusts may designate agents who agree to use their reasonable efforts to solicit purchases for the period of their appointment or to sell securities on a continuing basis.

     If DTE Energy and/or a DTE Energy Trust uses underwriters for a sale of securities, the underwriters will acquire the securities for their own account. The underwriters may resell the securities in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. The underwriters will be obligated to purchase all the securities offered if any of those securities are purchased. Any initial public offering price and any discounts or concessions allowed or re-allowed or paid to dealers will be described in the applicable prospectus supplement and may be changed from time to time.

     Underwriters, dealers and agents that participate in the distribution of the securities may be underwriters as defined in the Securities Act and any discounts or commissions they receive from DTE Energy and/or a DTE Energy Trust and any profit on their resale of the securities may be treated as underwriting discounts and commissions under the Securities Act. The applicable prospectus supplement will identify any underwriters, dealers or agents and will describe their compensation. DTE Energy and the DTE Energy Trusts may have agreements with the underwriters, dealers and agents to indemnify them against certain civil liabilities, including liabilities under the Securities Act. Underwriters, dealers and agents may engage in transactions with or perform services for us or our subsidiaries in the ordinary course of their businesses.

49

Trading Markets and Listing of Securities

     Unless otherwise specified in the applicable prospectus supplement, each class or series of securities will be a new issue with no established trading market, other than the common stock, which is listed on the New York Stock Exchange and the Chicago Stock Exchange. DTE Energy and the DTE Energy Trusts may elect to list any other class or series of securities on any exchange but is not obligated to do so. It is possible that one or more underwriters may make a market in a class or series of securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. Neither DTE Energy nor the DTE Energy Trusts can give any assurance as to the liquidity of the trading market for any of the securities.

Stabilization Activities

     Any underwriter may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Securities Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short-covering transactions involve purchases of the securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

Legal Matters

      The validity of the DTE Energy securities will be passed upon for DTE Energy by Thomas A. Hughes, Associate General Counsel. In addition, other customary legal matters relating to the offering of the securities, including matters relating to our due incorporation, legal existence and authorized capitalization, will be passed upon for DTE Energy by Thomas A. Hughes, Associate General Counsel. Mr. Hughes beneficially owns approximately 5,542 shares of DTE Energy common stock and holds options to purchase an additional 20,250 shares. The validity of the securities issued by the DTE Energy Trusts and certain matters of Delaware law will be passed upon for the DTE Energy Trusts by Richards, Layton & Finger, P.A., special Delaware counsel to the DTE Energy Trusts. Except as otherwise set forth in a prospectus supplement, certain legal matters relating to the securities will be passed upon for any underwriters, dealers or agents by Thelen Reid & Priest LLP, New York, New York. Thelen Reid & Priest LLP will rely on the opinion of Mr. Hughes with respect to Michigan law and the opinion of Richards, Layton & Finger, P.A. with respect to Delaware law.

Experts

      The consolidated financial statements and the related financial statement schedule of DTE Energy Company incorporated in this prospectus by reference from our Current Report on Form 8-K filed September 20, 2002 have been audited by Deloitte & Touche LLP, independent auditors, as stated in their report, which is incorporated herein by

reference, and have been so incorporated in reliance upon the report of such firm given upon their authority as experts in accounting and auditing.

     With respect to the unaudited interim financial information for the periods ended March 31, 2002 and 2001 and June 30, 2002 and 2001 that are incorporated herein by reference, Deloitte & Touche LLP has applied limited procedures in accordance with professional standards for a review of such information. However, as stated in their reports included in DTE Energy’s Quarterly Reports on Form 10-Q for the quarters ended March 31, 2002 and June 30, 2002 and incorporated by reference herein, they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their reports on such information should be restricted in light of the limited nature of the review procedures applied. Deloitte & Touche LLP are not subject to the liability provisions of Section 11 of the Securities Act of 1933 for their reports on the unaudited interim financial information because those reports are not “reports” or a “part” of the registration statement prepared or certified by an accountant within the meaning of Sections 7 and 11 of the Act.

Incorporation by Reference

     The SEC allows us to “incorporate by reference” the information we file with them, which means that we can disclose important information to you by referring you to those documents. The information incorporated by reference is an important part of this prospectus, and information that we file later with the SEC will automatically update and supersede this information. Until we sell all of the securities covered by this prospectus, we incorporate by reference the documents listed below and any future filings we make with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934 (other than information in such documents that is deemed not to be filed):

     There are no separate financial statements of the DTE Energy Trusts in this prospectus. We do not believe these financial statements would be material to investors because:

•  the DTE Energy Trusts are wholly-owned subsidiaries of DTE Energy, which files consolidated financial information under the Securities Exchange Act;

•  the DTE Energy Trusts will not have any independent operations other than issuing trust preferred securities and trust common securities, purchasing debt securities of DTE Energy and other necessary or incidental activities as described in this prospectus;

•  DTE Energy guarantees the trust preferred securities of the DTE Energy Trusts;

•  no other subsidiary of DTE Energy guarantees the trust preferred securities of the DTE Energy Trusts; and

•  the guarantee of the DTE Energy Trusts by DTE Energy is full and unconditional.
