CREATION OF THREE HUNDRED TWENTY-THIRD SERIES OF BONDS. GENERAL AND REFUNDING MORTGAGE BONDS, FLOATING RATE 1999 SERIES D TERMS OF BONDS OF FLOATING RATE 1999 SERIES D. SECTION 1. The Company hereby creates the Three hundred twenty-third series of bonds to be issued under and secured by the Original Indenture as amended to date and as further amended by this Supplemental Indenture, to be designated, and to be distinguished from the bonds of all other series, by the title "General and Refunding Mortgage Bonds, Floating Rate 1999 Series D" (elsewhere herein referred to as the "bonds of 1999 Series D"). The aggregate principal amount of bonds of 1999 Series D shall be limited to Forty million dollars ($40,000,000), except as provided in Sections 7 and 13 of Article II of the Original Indenture with respect to exchanges and replacements of bonds. The bonds of 1999 Series D shall mature on September 17, 2001 and shall be issued as registered bonds without coupons in denominations of $1,000 and any multiple thereof. The bonds of 1999 Series D will be issued in book-entry form through the facilities of The Depository Trust Company ("DTC"). Transfers or exchanges of beneficial interests in the bonds of 1999 Series D may be effected only through records maintained by DTC or its nominee. Payments of principal and interest on the Bonds will be made to DTC in immediately available funds as the principal of and interest on the bonds of 1999 Series D shall be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York, The State of New York in any coin or currency of the United States of America which at the time of payment is legal tender for public and private debts. The interest on bonds of 1999 Series D, whether in temporary or definitive form, shall be payable without presentation of such bonds and (subject to the provisions of this Section 1) only to or upon the written order of the registered holders thereof. The bonds of 1999 Series D shall bear interest at a rate per annum, reset quarterly, equal to three-month LIBOR (as defined below) plus seventeen basis points (.17%), as determined by the Calculation Agent (as defined below). Interest will be computed on the basis of a 360-day year and the actual number of days in the applicable Interest Period (as defined below). Interest is payable quarterly in arrears on March 15, June 15, September 15, and December 15 of each year, commencing September 15, 1999, except that the final payment of interest will be due on September 17, 2001, instead of September 15, 2001 (each an "Interest Payment Date"), for the period commencing on and including the immediately preceding Interest Payment Date and ending on and including the day preceding the next Interest Payment Date (each an "Interest Period"), with the exception that the first Interest Period shall commence on and include August 27, 1999. Interest is payable to the persons in whose names the bonds of 1999 Series D are registered at the close of business on the fifteenth calendar day, whether or not a Business Day (as defined below), prior to the Interest Payment Date. The interest rate on the bonds of 1999 Series D may not exceed the "Maximum Rate", which is defined to mean the rate of interest equal to 15% per annum or such higher rate as may be established from time to time by the Board of Directors of the Company. If any Interest Payment Date, other than at stated maturity, for the bonds of 1999 Series D would otherwise be a day that is not a Business Day, such Interest Payment Date will be postponed to the next day that is a Business Day, except that if such Business Day is in the next succeeding calendar month, such Interest 9 7 Payment Date shall be the immediately preceding Business Day. If the stated maturity for the bonds of 1999 Series D falls on a day which is not a Business Day, payment of principal and interest with respect to the bonds of 1999 Series D will be paid on the next succeeding Business Day with the same force and effect as if made on such date and no interest on such payment will accrue from and after such date. The interest rate for each Interest Period shall be determined by the Calculation Agent in accordance with the following provisions: The per annum rate of interest for each Interest Period will be three-month LIBOR on the second Business Day preceding the relevant Interest Reset Date (as defined below) for such Interest Period (the "Interest Determination Date") plus the applicable spread described above. The Interest Determination Date for the first Interest Period shall be August 25, 1999. "LIBOR" for each subsequent Interest Period shall be determined by the Calculation Agent in accordance with the following provisions: (i) On each Interest Determination Date, the Calculation Agent shall ascertain the offered rate for three-month deposits in U.S. dollars in the London interbank market, which appears on the Telerate Page 3750, as of 11:00 a.m. (London time) on such Interest Determination Date. (ii) If such rate does not appear on the Telerate Page 3750, or the Telerate Page 3750 is unavailable, the Calculation Agent shall request each of four major banks in the London interbank market (the "Reference Banks") to provide the Calculation Agent with its offered quotation (expressed as a rate per annum) for three-month deposits in U.S. dollars to leading banks in the London interbank market at approximately 11:00 a.m. (London time) on the Interest Determination Date. If at least two such quotations are provided, LIBOR in respect of the Interest Determination Date, will be the arithmetic mean of such quotations. (iii) If less than two of the Reference Banks provide the Calculation Agent with such offered quotations, LIBOR in respect of that Interest Determination Date shall be the arithmetic mean of the rates quoted by three major banks in The City of New York (selected by the Calculation Agent) at approximately 11:00 a.m., New York City time, on that Interest Determination Date for three-month loans in U.S. dollars to leading European banks, in a principal amount equal to an amount of not less than $1,000,000 that is representative for a single transaction in such market at such time; provided, however, that if the banks selected as aforesaid by the Calculation Agent are not quoting as mentioned in this sentence, LIBOR shall be LIBOR in effect on such Interest Determination Date. "Interest Reset Date" means, with respect to any Interest Period, the first day of such Interest Period. "Business Day" means any day (other than a Saturday or Sunday) on which banking institutions in The City of New York are open for business and which is also a London Banking Day. "London Banking Day" means any day (other than a Saturday or Sunday) on which dealings in deposits are transacted in the London interbank market. "Telerate Page 3750" means the display designated as page "3750" on the Bridge Telerate, Inc. (or such other page as may replace that page on that service for the purpose of displaying the LIBOR Index on a daily basis). All percentages resulting from any calculation on the bonds of 1999 Series D shall be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)), and U.S. dollar amounts used in or resulting from such calculations shall be rounded to the nearest cent (with one-half cent being rounded upward). 10 8 The Company agrees that, so long as any of the bonds of 1999 Series D remain outstanding, it shall maintain under appointment an agent (the "Calculation Agent"), initially Bankers Trust Company, to calculate the rate of interest payable on the Bonds in respect of each Interest Period as provided in Section 3 below. If the Calculation Agent is unable or unwilling to continue to act as such, or if the Calculation Agent fails to establish the applicable rate of interest for any Interest Period, or if the Company removes the Calculation Agent, the Company shall appoint the office of another bank to act as the Calculation Agent; provided, however, that the Calculation Agent shall not resign or be removed until acceptance of an appointment by a successor as evidenced by an appropriate agreement entered into by the Company and such successor Calculation Agent. Each bond of 1999 Series D shall be dated the date of its authentication and interest shall be payable on the principal represented thereby from the March 15, June 15, September 15 or December 15 next preceding the date thereof to which interest has been paid on bonds of 1999 Series D, unless the bond is authenticated on a date to which interest has been paid, in which case interest shall be payable from the date of authentication, or unless the date of authentication is prior to September 15, 1999, in which case interest shall be payable from August 27, 1999 on the bond of 1999 Series D originally evidencing the debt represented thereby. The bonds of 1999 Series D in definitive form shall be, at the election of the Company, fully engraved or shall be lithographed or printed in authorized denominations as aforesaid and numbered 1 and upwards (with such further designation as may be appropriate and desirable to indicate by such designation the form, series and denomination of bonds of 1999 Series D). Until bonds of 1999 Series D in definitive form are ready for delivery, the Company may execute, and upon its request in writing the Trustee shall authenticate and deliver in lieu thereof, bonds of 1999 Series D in temporary form, as provided in Section 10 of Article II of the Indenture. Temporary bonds of 1999 Series D, if any, may be printed and may be issued in authorized denominations in substantially the form of definitive bonds of 1999 Series D, but with such omissions, insertions and variations as may be appropriate for temporary bonds, all as may be determined by the Company. Interest on any bond of 1999 Series D which is payable on any Interest Payment Date and is punctually paid or duly provided for shall be paid to the person in whose name that bond, or any previous bond to the extent evidencing the same debt as that evidenced by that bond, is registered at the close of business on the regular record date for such interest, which regular record date shall be the fifteenth calendar day (whether or not a business day) next preceding such Interest Payment Date. If the Company shall default in the payment of the interest due on any Interest Payment Date on the principal represented by any bond of 1999 Series D, such defaulted interest shall forthwith cease to be payable to the registered holder of that bond on the relevant regular record date by virtue of his having been such holder, and such defaulted interest may be paid to the registered holder of that bond (or any bond or bonds of 1999 Series D issued upon transfer or exchange thereof) on the date of payment of such defaulted interest or, at the election of the Company, to the person in whose name that bond (or any bond or bonds of 1999 Series D issued upon transfer or exchange thereof) is registered on a subsequent record date established by notice given by mail by or on behalf of the Company to the holders of bonds of 1999 Series D not less than ten (10) days preceding such subsequent record date, which subsequent record date shall be at least five (5) days prior to the payment date of such defaulted interest. REDEMPTION OF BONDS OF 1999 SERIES D. SECTION 2. The bonds of 1999 Series D shall not be redeemable prior to stated maturity. The bonds of 1999 Series D shall not be entitled to or subject to any sinking fund. EXCHANGE AND TRANSFER. At the option of the registered holder, any bonds of 1999 Series D, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of 11 9 Manhattan, The City of New York, The State of New York, together with a written instrument of transfer (if so required by the Company or by the Trustee) in form approved by the Company duly executed by the holder or by its duly authorized attorney, shall be exchangeable for a like aggregate principal amount of bonds of 1999 Series D of other authorized denominations, upon the terms and conditions specified herein and in Section 7 of Article II of the Indenture. Bonds of 1999 Series D shall be transferable at the office or agency of the Company in the Borough of Manhattan, The City of New York, The State of New York. The Company waives its rights under Section 7 of Article II of the Indenture not to make exchanges or transfers of bonds of 1999 Series D during any period of ten (10) days next preceding any interest payment date for such bonds. Bonds of 1999 Series D, in definitive and temporary form, may bear such legends as may be necessary to comply with any law or with any rules or regulations made pursuant thereto or with the rules or regulations of any stock exchange or to conform to usage with respect thereto. CALCULATION AGENT SECTION 3. (a) The Company hereby appoints Bankers Trust Company as Calculation Agent (in such capacity, the "Calculation Agent") of the Company with respect to the bonds of 1999 Series D, and the Calculation Agent hereby accepts its obligations as set forth in this Supplemental Indenture upon the terms and conditions set forth herein. (b) As soon as reasonably practical on or after each Interest Determination Date, the Calculation Agent shall determine LIBOR and notify the Company thereof and the resulting interest rate. Upon the request of the beneficial owner of any bond of 1999 Series D, the Calculation Agent will provide the interest rate then in effect and, if determined, the applicable interest rate that will become effective as of the next Interest Reset Date. All interest rate determinations made by the Calculation Agent with respect to the bonds of 1999 Series D shall, in the absence of manifest error, be conclusive for all purposes and binding upon the Company. (c) The Calculation Agent shall be entitled to such compensation for its services as the Calculation Agent and the Company may agree, and the Company shall pay such compensation and shall reimburse the Calculation Agent for all reasonable expenses, disbursements and advances incurred or made by the Calculation Agent in connection with the services rendered by it as Calculation Agent. (d) The Calculation Agent shall incur no liability for, or in respect of, any action taken, omitted to be taken or suffered by it in reliance upon any bond of 1999 Series D, certificate, affidavit, instruction, notice, request, direction, order, statement or other paper, document or communication reasonably believed by it to be genuine. Any order, certificate, affidavit, instruction, notice, request, direction, statement or other communication from the Company made or given by it and sent, delivered or directed to the Calculation Agent under, pursuant to or as permitted by any provision of this Supplemental Indenture shall be sufficient for purposes of this Supplemental Indenture if such communication is in writing and signed by any officer of the Company. The Calculation Agent may consult with counsel satisfactory to it (which counsel may be counsel for the Company) and the opinion of such counsel shall constitute full and complete protection of the Calculation Agent with respect to any action taken, omitted to be taken or suffered by it hereunder in good faith and in accordance with and in reliance upon the opinion of such counsel. In acting under this Supplemental Indenture, the Calculation Agent (in its capacity as such) does not assume any obligation to, or any relationship of agency or trust for or with, the holders of the bonds of 1999 Series D. (e) The Calculation Agent shall be obligated only to perform such duties as are specifically set forth herein and no other duties or obligations on the part of the Calculation Agent, in its capacity as such, shall be implied hereby. 12 10 (f) The Calculation Agent may at any time terminate its appointment as Calculation Agent by giving no less than ninety (90) days' written notice to the Company, unless the Company consents in writing to a shorter time. Upon receipt of notice of termination by the Calculation Agent, the Company agrees promptly to appoint a successor Calculation Agent. The Company may terminate the appointment of the Calculation Agent at any time by giving written notice to the Calculation Agent of such termination and specifying the date when such termination shall become effective; provided, however, that no termination by the Calculation Agent or by the Company shall become effective prior to the date of the appointment by the Company, as provided below, of a successor Calculation Agent and the acceptance of such appointment by such successor Calculation Agent. Upon termination by either party pursuant to the provisions of this paragraph, the Calculation Agent shall be entitled to the payment of any compensation owed to it by the Company hereunder, as provided by paragraph (c) above, and the provisions of paragraph (h) below shall remain in effect following such termination. (g) Any successor Calculation Agent appointed by the Company following termination of the appointment of the Calculation Agent pursuant to the provisions of paragraph (f) hereof shall execute and deliver to the Calculation Agent and to the Company an instrument accepting such appointment, and thereupon such successor Calculation Agent shall, without any further act or instrument, become vested with all the rights, immunities, duties and obligations of the Calculation Agent, with like effect as if originally named as Calculation Agent hereunder, and the Calculation Agent shall thereupon be obligated to transfer and deliver, and such successor Calculation Agent shall be entitled to receive and accept, copies of any available records maintained by the Calculation Agent in connection with the performance of its obligations hereunder. (h) The Company shall indemnify and hold free and harmless the Calculation Agent, its officers and employees from and against all actions, claims, damages, liabilities, losses and expenses (including reasonable legal fees and expenses) relating to or arising out of actions, or omissions in any capacity hereunder, except actions, claims, damages, liabilities, losses and expenses caused by the gross negligence or wilful misconduct of the Calculation Agent, its officers or employees. (i) Any corporation into which the Calculation Agent may be merged, converted or consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Calculation Agent may be a party, or any corporation to which the Calculation Agent may sell or otherwise transfer all or substantially all of its corporate trust business, shall, to the extent permitted by applicable law, become the Calculation Agent under this Supplemental Indenture without the execution of any paper or any further act by the parties hereto. The Calculation Agent will give prompt written notice to the Company and the Trustee (if other than Bankers Trust Company) of any such merger, conversion or consolidation. (j) Any notice or other communication given hereunder shall be delivered in person, sent by letter, telecopy or telex or communicated by telephone (subject, in the case of communication by telephone, to written confirmation dispatched within 24 hours) to such address as the party to receive such notice may have previously specified. (k) The terms and conditions of the appointment of the Calculation Agent may be amended only by means of a written instrument duly executed and delivered by or on behalf of the Company and the Calculation Agent; provided, that, except as required by law, or as agreed by the Company and the Calculation Agent, such amendment need not be in the form of an amended or further Supplemental Indenture. (l) Except as provided herein, the provisions of this Section 3 are solely for the benefit of the Company and the Calculation Agent hereto and their successors and assigns and no other person shall acquire or have any rights under or by virtue hereof. 13 11 THE DETROIT EDISON COMPANY GENERAL AND REFUNDING MORTGAGE BOND FLOATING RATE 1999 SERIES D, DUE SEPTEMBER 17, 2001 $40,000,000 No. 1 THE DETROIT EDISON COMPANY (hereinafter called the "Company"), a corporation of the State of Michigan, for value received, hereby promises to pay to CEDE & Co. or registered assigns, at its office or agency in the Borough of Manhattan, The City and State of New York, the principal sum of $40,000,000 in lawful money of the United States of America on the seventeenth day of September 17, 2001, and to pay interest thereon as provided below, at such office or agency, in like lawful money, from August 27, 1999, to the person in whose name this bond is registered at the close of business on the related regular record date as provided below, or (subject to certain exceptions provided in the Indenture hereinafter mentioned), until the Company's obligation with respect to payment of said principal shall have been discharged, all as provided, to the extent and in the manner specified in such Indenture hereinafter mentioned on the reverse hereof and in the supplemental indenture pursuant to which this bond has been issued. The bonds of 1999 Series D will bear interest at a rate per annum, reset quarterly, equal to three-month LIBOR (as defined below) plus seventeen basis points (.17%), as determined by the Calculation Agent (as defined below). Interest will be computed on the basis of a 360-day year and the actual number of days in the applicable Interest Period (as defined below). Interest is payable quarterly in arrears on March 15, June 15, September 15, and December 15 of each year, commencing September 15, 1999, except that the final payment of interest will be due on September 17, 2001, instead of September 15, 2001 (each an "Interest Payment Date"), for the period commencing on and including the immediately preceding Interest Payment Date and ending on and including the day preceding the next Interest Payment Date (each an "Interest Period"), with the exception that the first Interest Period shall commence on and include August 27, 1999. Interest is payable to the persons in whose names the bonds of 1999 Series D are registered at the close of business on the related regular record date, which shall be the fifteenth calendar day, whether or not a Business Day (as defined below), prior to the Interest Payment Date. The interest rate on the bonds of 1999 Series D may not exceed the "Maximum Rate", which is defined to mean the rate of interest equal to 15% per annum or such higher rate as may be established from time to time by the Board of Directors of the Company. If any Interest Payment Date, other than at stated maturity, for the bonds of 1999 Series D would otherwise be a day that is not a Business Day, such Interest Payment Date will be postponed to the next day that is a Business Day, except that if such Business Day is in the next succeeding calendar month, such Interest Payment Date shall be the immediately preceding Business Day. If the stated maturity for the bonds of 1999 Series D falls on a day which is not a Business Day, payment of principal and interest with respect to the bonds of 1999 Series D will be paid on the next succeeding Business Day with the same force and effect as if made on such date and no interest on such payment will accrue from and after such date. The interest rate for each Interest Period will be determined by the Calculation Agent in accordance with the following provisions: The per annum rate of interest for each Interest Period will be three-month LIBOR on the second Business Day preceding the relevant Interest Reset Date (as defined below) for such Interest Period (the "Interest Determination Date") plus the applicable spread described above. The Interest Determination Date for the first Interest Period will be August 25, 1999. "LIBOR" for each subsequent Interest 14 12 Period will be determined by the Calculation Agent in accordance with the following provisions: (i) On each Interest Determination Date, the Calculation Agent will ascertain the offered rate for three-month deposits in U.S. dollars in the London interbank market, which appears on the Telerate Page 3750, as of 11:00 a.m. (London time) on such Interest Determination Date. (ii) If such rate does not appear on the Telerate Page 3750, or the Telerate Page 3750 is unavailable, the Calculation Agent will request each of four major banks in the London interbank market (the "Reference Banks") to provide the Calculation Agent with its offered quotation (expressed as a rate per annum) for three-month deposits in U.S. dollars to leading banks in the London interbank market at approximately 11:00 a.m. (London time) on the Interest Determination Date. If at least two such quotations are provided, LIBOR in respect of the Interest Determination Date, will be the arithmetic mean of such quotations. (iii) If less than two of the Reference Banks provide the Calculation Agent with such offered quotations, LIBOR in respect of that Interest Determination Date will be the arithmetic mean of the rates quoted by three major banks in The City of New York (selected by the Calculation Agent) at approximately 11:00 a.m., New York City time, on that Interest Determination Date for three-month loans in U.S. dollars to leading European banks, in a principal amount equal to an amount of not less than $1,000,000 that is representative for a single transaction in such market at such time; provided, however, that if the banks selected as aforesaid by the Calculation Agent are not quoting as mentioned in this sentence, LIBOR will be LIBOR in effect on such Interest Determination Date. "Interest Reset Date" means, with respect to any Interest Period, the first day of such Interest Period. "Business Day" means any day (other than a Saturday or Sunday) on which banking institutions in The City of New York are open for business and which is also a London Banking Day. "London Banking Day" means any day (other than a Saturday or Sunday) on which dealings in deposits are transacted in the London interbank market. "Telerate Page 3750" means the display designated as page "3750" on the Bridge Telerate, Inc. (or such other page as may replace that page on that service for the purpose of displaying the LIBOR Index on a daily basis). All percentages resulting from any calculation on the bonds of 1999 Series D will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)), and U.S. dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upward). The Company has agreed that, so long as any of the bonds of 1999 Series D remain outstanding, it will maintain under appointment an agent (the "Calculation Agent"), initially Bankers Trust Company, to calculate the rate of interest payable on the Bonds in respect of each Interest Period. If the Calculation Agent is unable or unwilling to continue to act as such, or if the Calculation Agent fails to establish the applicable rate of interest for any Interest Period, or if the Company removes the Calculation Agent, the Company will appoint the office of another bank to act as the Calculation Agent; provided, however, that the Calculation Agent shall not resign or be removed until acceptance of an appointment by a successor as evidenced by an appropriate agreement entered into by the Company and such successor Calculation Agent. 15 13 Reference is hereby made to the further provisions of this bond set forth on the reverse hereof and such further provisions shall for all purposes have the same effect as though set forth at this place. This bond shall not be valid or become obligatory for any purpose until Bankers Trust Company, the Trustee under the Indenture hereinafter mentioned on the reverse hereof, or its successor thereunder, shall have signed the form of certificate endorsed hereon. IN WITNESS WHEREOF, THE DETROIT EDISON COMPANY has caused this instrument to be executed on its behalf by its Vice President and Treasurer, with his manual or facsimile signature, and its corporate seal, or a facsimile thereof, to be impressed or imprinted hereon and the same to be attested by its Secretary or its Assistant Corporate Secretary by manual or facsimile signature.

The bonds of 1999 Series D, including this bond, shall not be redeemable prior to stated maturity. The bonds of 1999 Series D, including this bond, shall not be entitled or subject to a sinking fund. In case an event of default, as defined in the Indenture, shall occur, the principal of all the bonds issued thereunder may become or be declared due and payable, in the manner, with the effect and subject to the conditions, provided in the Indenture.
