TITLE AND TERMS OF THE SECURITIES

     SECTION 2.01. Title of the Securities; Stated Maturity. This Twenty-Sixth Supplemental Indenture hereby establishes a series of Securities, which shall be known as the Company’s “2008 Series KT Variable Rate Senior Notes due 2020” (the “Notes”). For purposes of the Original Indenture, the Notes shall constitute a single series of Securities. The Stated Maturity on which the principal of the Notes shall be due and payable will be July 1, 2020. The Notes are being issued to secure the Company’s obligations to the MSF under the Loan Agreement.

     SECTION 2.02. Certain Variations from the Original Indenture.

     (a) The Notes shall have the benefit of the provisions of Article Four of the Original Indenture and shall have the benefit of, or be subject to, the other related provisions of the Original Indenture relating to the grant of security, including (for avoidance of doubt and not for purposes of limitation) the Granting Clause, the definitions of “Deliverable Mortgage Bonds,” “Deliverable Securities,” “Designated Mortgage Bonds,” “Grant,” “Mortgage,” “Mortgage Bonds,” “Mortgage Trustee,” “Previously Delivered Mortgage Bonds,” and “Trust Estate,” Section 301(20), Section 301(a), Section 301(b), Section 301(d), and Article VI, subject, in each case, to the release provisions provided for in Section 4.02 herein. In addition, on and after the Release Date, unless Substitute Mortgage Bonds are issued to secure the Notes, the Notes shall have the benefit of the additional covenants set forth in Article Three hereof.

     (b) In the event the Company desires to provide for the payment of the Notes, in lieu of defeasing the Notes in accordance with Section 503 of the Original Indenture, it shall either redeem an equal principal amount of the 2008KT Bonds or take such action as shall be required by Article VIII of the Bond Indenture to defease an equal principal amount of the 2008KT Bonds. Pursuant to Section 2.03(c) hereof, such redemption or defeasance shall result in the discharge of the Company’s obligation with respect to the Notes and the cancellation of the Notes.

     (c) Any amount payable by the Company in respect of principal of the Notes, whether at maturity or prior to maturity by redemption or upon redemption or acceleration or otherwise, in a circumstance where there has not been a corresponding payment of principal of 2008KT Bonds, shall be applied simultaneously to the redemption or defeasance of an equal principal amount of

2008KT Bonds in accordance with the Bond Indenture. In the event the amount so paid is insufficient to provide for such redemption or defeasance, the Company shall pay such additional amounts as shall be necessary to make up the deficiency.

     SECTION 2.03. Amount, Assignability and Redemption.

     (a) The aggregate principal amount of Notes that may be issued under this Twenty-Sxith Supplemental Indenture is limited to $32,375,000 (except as provided in Section 301(2) of the Original Indenture). The Notes shall be issuable only as Registered Securities without coupons and, as permitted by Section 301 and Section 302 of the Original Indenture, in denominations of $1,000 and integral multiples thereof to the Bond Trustee as assignee of the MSF, pursuant to the Loan Agreement. The Notes shall not be further assignable or transferable except as may be required to effect a transfer to any successor Bond Trustee.

     (b) The Notes may bear such legends as may be necessary to refer to the Loan Agreement or to comply with any law or with any rules or regulations made pursuant thereto or to evidence the limited assignability.

     (c) Upon payment of the principal, premium, if any, or interest on the 2008KT Bonds, whether at maturity or prior to maturity by redemption or otherwise, or upon provision for the payment thereof having been made in accordance with Article IV or VIII of the Bond Indenture, Notes in a principal amount equal to the principal amount of the 2008KT Bonds shall, to the extent of such payment of principal, premium or interest, be deemed fully paid and the obligation of the Company thereunder to make such payment shall forthwith cease and be discharged, and, in the case of the payment of principal and premium, if any, such Notes shall be surrendered for cancellation or presented for appropriate notation to the Trustee.

     (d) The Notes shall be redeemed on the date and in the principal amount which corresponds to the redemption date for, and the principal amount to be redeemed of, the 2008KT Bonds.

     (e) In the event of an Event of Default under the Bond Indenture and the acceleration of the 2008KT Bonds, the Notes shall be redeemable in whole upon receipt by the Trustee of a written demand (Redemption Demand) from the Bond Trustee indicating that it has paid accelerated principal.

     SECTION 2.04. Certain Terms of the Notes.

     (a) The Notes shall bear interest at the rate of interest established for the 2008KT Bonds from time to time in accordance with the Bond Indenture on the principal amount thereof from the date of original issue, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, until the principal of the Notes becomes due and payable, and on any overdue principal and premium and (to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest at the same rate per annum during such overdue period. Interest on the Notes will be payable on such dates as interest shall be payable on the 2008KT Bonds (each such date, an “Interest Payment Date”). Payment of interest on the 2008KT Bonds shall be deemed to constitute payment of interest on the Notes. The

amount of interest payable for any period shall be computed on the same basis as interest on the 2008KT Bonds pursuant to the Bond Indenture.

     (b) In the event that any Interest Payment Date, redemption date or other date of Maturity of the Notes is not a Business Day, then payment of the amount payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), in each case with the same force and effect as if made on such date. The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date with respect to any Note will, as provided in the Original Indenture, be paid to the person in whose name the Note (or one or more Predecessor Securities, as defined in the Original Indenture) is registered at the close of business on the relevant record date for such interest installment, which shall be the same as the record date for the 2008KT Bonds with respect to the relevant Interest Payment Date (the “Regular Record Date”). Any such interest installment not punctually paid or duly provided for shall forthwith cease to be payable to the registered Holders on such Regular Record Date, and may either be paid to the person in whose name the Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date to be fixed by the Trustee for the payment of such defaulted interest, notice whereof shall be given to the registered Holders of the Notes not less than ten days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Original Indenture. The principal of, and premium, if any, and the interest on the Notes shall be payable at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, the City of New York, in any coin or currency of the United States of America that at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made at the option of the Company by check mailed to the registered Holder at the close of business on the Regular Record Date at such address as shall appear in the Security Register. Any waiver or rescission of a declaration of acceleration of principal of the 2008KT Bonds shall constitute a waiver or rescission with respect to the Notes.

     (c) The Notes are not subject to repayment at the option of the Holders thereof and are not subject to any sinking fund, except to the extent that the Bond Trustee, or its successor in interest, may have exercised its rights pursuant to Section 2.03 hereof. As provided in the form of the Note attached hereto as Exhibit A, the Notes are subject to Optional Redemption and Extraordinary Optional Redemption, as a whole or in part, and Special Optional Redemption, in whole, by the Company prior to Stated Maturity of the principal thereof upon the same terms as the 2008KT Bonds. Except as modified in the form of Note, redemptions shall be effected in accordance with Article Twelve of the Original Indenture.

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

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

ARTICLE THREE

ADDITIONAL COVENANTS

          SECTION 3.01. Limitations on Liens.

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

          The foregoing restriction will not apply to:

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

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

      (iii) Liens on Operating Property to secure the cost of acquisition, construction, development or substantial repair, alteration or improvement of such property or to secure indebtedness incurred to provide funds for any of these purposes or for reimbursement of funds previously expended for any of these purposes, provided the Liens are created or assumed contemporaneously with, or within 18 months after, the acquisition or the completion of substantial repair or alteration, construction, development or substantial improvement or within 6 months thereafter pursuant to a commitment for financing arranged with a lender or investor within such 18-month period;

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

      (v) Any extension, renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any Lien referred to in the exceptions listed above, provided, however, that the principal amount of Debt secured thereby and not otherwise authorized by those exceptions listed above shall not exceed the principal amount of Debt,

plus any premium or fee payable in connection with any such extension, renewal or replacement, so secured at the time of such extension, renewal or replacement.

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

     SECTION 3.02. Limitations on Sale and Lease-Back Transactions.

This restriction will not apply if (a) the Company would be entitled pursuant to Section 3.01(a) above to issue, assume, guarantee or permit to exist Debt secured by a Lien on the Operating Property without equally and ratably securing the Notes, (b) after giving effect to the Sale and Lease-Back Transaction, pursuant to Section 3.01(b) above, the Company could incur at least $1.00 of additional Debt secured by Liens (other than Liens permitted by clause (a)), or (c) the Company applies within 180 days an amount equal to, in the case of a sale or transfer for cash, the net proceeds (not less than the fair value of the Operating Property so leased), and, otherwise, an amount equal to the fair value (as determined by the Board of Directors of the Company) of the Operating Property so leased to the retirement of Notes or other Debt of the Company ranking equally with the Notes; provided, however, that any such retirement of Notes shall be in accordance with the terms and provisions of the Indenture and the Notes; provided, further, that the amount to be applied to such retirement of Notes or other Debt shall be reduced by an amount equal to the sum of (a) an amount equal to the redemption price with respect to Notes delivered within such one hundred eighty (180)-day period to the Trustee for retirement and cancellation and (b) the principal amount, plus any premium or fee paid in connection with any redemption in accordance with the terms of other Debt voluntarily retired by the Company within such one hundred eighty (180)-day period, excluding in each case retirements pursuant to mandatory sinking fund or prepayment provisions and payments at Stated Maturity.

     THE DETROIT EDISON COMPANY, a corporation duly organized and existing under the laws of the State of Michigan (the “Company,” which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to The Bank of New York Mellon Trust Company, N.A., as Bond Trustee, or registered assigns, at the office or agency of the Company in the City of New York, New York, the principal sum of                                          Dollars ($                    ) on July 1, 2020 (the “Stated Maturity”), in the coin or currency of the United States, and to pay interest thereon from the Original Issue Date shown above, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, in arrears on each Interest Payment Date as specified above, commencing on the first date on which interest is payable on the 2008KT Bonds, and on the Stated Maturity at the rate per annum shown above (the “Interest Rate”) until the principal hereof is paid or made available for payment, and on any overdue principal and premium and on any overdue installment of interest. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered on the Regular Record Date as specified above next preceding such Interest Payment Date. This Note is being issued to the Bond Trustee, as assignee of the Michigan Strategic Fund (the “MSF”), pursuant to the Company’s obligations under the Loan Agreement dated as of July 1, 2008 (the “Loan Agreement”) between the MSF and the Company relating to the Michigan Strategic Fund Variable Rate Limited Obligation Refunding Revenue Bonds (The Detroit Edison Company Exempt Facilities Project), Series 2008KT (the “2008KT Bonds”), which are issued under the Trust Indenture dated as of July 1, 2008 (the “Bond Indenture”) between the MSF and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Bond Trustee”). Except as otherwise provided in the Indenture, any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the

close of business on a Special Record Date for the payment of such defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Notes of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange, if any, on which the Notes of this series shall be listed, and upon such notice as may be required by any such exchange, all as more fully provided in the Indenture.

     Payments of interest on this Note will include interest accrued to but excluding the respective Interest Payment Dates. Interest payments for this Note shall be computed and paid on the same basis as interest on the 2008KT Bonds pursuant to the Bond Indenture. The Company shall pay interest on overdue principal and premium, if any, and, to the extent lawful, on overdue installments of interest at the rate per annum borne by this Note. In the event that any Interest Payment Date, Redemption Date or Maturity Date is not a Business Day, then the required payment of principal, premium, if any, and interest will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay), in each case with the same force and effect as if made on such date. “Business Day” means any day except a Saturday, Sunday or other day (i) on which commercial banks located in the cities in which the Principal Office of the Trustee, the Principal Office of the Company, the Principal Office of the Remarketing Agent, the Principal Office of the Auction Agent during any Auction Period or the Principal Office of the Paying Agent, each as defined in the Bond Indenture, are located are required or authorized by law or regulation to remain closed or are closed, or (ii) on which The New York Stock Exchange is closed.

     Payment of principal of, premium, if any, and interest on the Notes shall be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. Payments of principal, premium, if any, and interest due at the Stated Maturity or earlier redemption of such Securities shall be made at the office of the Paying Agent upon surrender of such Securities to the Paying Agent. Payments of interest shall be made, at the option of the Company, subject to such surrender where applicable, by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register.

     UNTIL THE RELEASE DATE (AS DEFINED BELOW), THIS NOTE SHALL BE SECURED BY GENERAL AND REFUNDING MORTGAGE BONDS, 2008 SERIES KT (THE “MORTGAGE BONDS”) ISSUED AND DELIVERED BY THE COMPANY TO THE TRUSTEE (AS DEFINED BELOW) UNDER THE COMPANY’S SUPPLEMENTAL INDENTURE DATED AS OF JULY 1, 2008, SUPPLEMENTING THE MORTGAGE AND DEED OF TRUST DATED AS OF OCTOBER 1, 1924 BETWEEN THE COMPANY AND J.P. MORGAN TRUST COMPANY, NATIONAL ASSOCIATION (THE “MORTGAGE TRUSTEE”), PLEDGED BY THE COMPANY FOR THE BENEFIT OF THE HOLDERS OF THE NOTES TO THE TRUSTEE UNDER THE INDENTURE (THE “MORTGAGE”). ON THE RELEASE DATE, THE NOTES SHALL CEASE TO BE SECURED BY SUCH MORTGAGE BONDS AND, AT THE COMPANY’S OPTION, SHALL EITHER (1) BECOME UNSECURED GENERAL OBLIGATIONS OF THE COMPANY OR (2) BE SECURED BY SUBSTITUTE MORTGAGE BONDS UNDER A SUBSTITUTE MORTGAGE.

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

     This Note is one of a duly authorized series of Securities of the Company (herein sometimes referred to as the “Notes”), specified in the Indenture, all issued or to be issued in one or more series under and pursuant to a Collateral Trust Indenture dated as of June 30, 1993 (the “Original Indenture”) duly executed and delivered between the Company and The Bank of New York Mellon Trust Company, N.A., as successor Trustee (herein referred to as the “Trustee”), as supplemented through and including a Twenty-Sixth Supplemental Indenture dated as of July 1, 2008 (together with the Original Indenture, the “Indenture”) between the Company and the Trustee, to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the registered Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered.

     The Notes are not subject to repayment at the option of the Holders thereof and are not subject to any sinking fund, except to the extent that the Bond Trustee, or its successor in interest, may have exercised its rights pursuant to Section 2.03 of the aforesaid Twenty-Sixth Supplemental Indenture. The Notes are subject to Optional Redemption and Extraordinary Optional Redemption, as a whole or in part, and Special Optional Redemption, in whole, by the Company prior to Stated Maturity of the principal thereof upon the same terms as the 2008KT Bonds are subject to redemption. Upon payment of the principal or premium, if any, on the 2008KT Bonds, whether at maturity or prior to maturity by redemption or otherwise, or upon provision for the payment thereof having been made in accordance with Article IV or VIII of the Bond Indenture, or upon payment of interest on the 2008KT Bonds, Notes in a principal amount equal to the principal amount of the 2008KT Bonds so paid, or interest on Notes in an amount equal to the interest on the 2008KT Bonds so paid, as the case may be, shall, to the extent of such payment, be deemed fully paid and the obligation of the Company thereunder to make such payment shall forthwith cease and be discharged, and, in the case of the payment of principal and premium, if any, such Notes shall be surrendered for cancellation or presented for appropriate notation to the Trustee.

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

     Notice of any Optional, Extraordinary Optional or Special Optional Redemption will be mailed at least 30 days but not more than 60 days before the Optional, Extraordinary Optional or Special Optional Redemption Date, as the case may be, to the Holder hereof at its registered address.

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

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

     If the Company elects to redeem all or a portion of the Notes, the redemption will be conditional upon receipt by the Paying Agent or the Trustee of monies sufficient to pay the Redemption Price. If the Notes are only partially redeemed by the Company, the Trustee shall select which Notes are to be redeemed in a manner it deems fair and appropriate in accordance with the terms of the Indenture.

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

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

     The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Note upon compliance by the Company with certain conditions set forth therein. In the event the Company desires to provide for the payment of Notes, in lieu of defeasing the Notes in accordance with the Indenture, the Company shall either redeem an equal principal amount of 2008KT Bonds or take such action as shall be required by the Bond Indenture to defease an equal principal amount of 2008KT Bonds.

     Any amount payable by the Company in respect of principal of the Notes, whether at maturity or prior to maturity by redemption or otherwise, in a circumstance where there has not been a corresponding payment of principal of 2008KT Bonds, shall be applied simultaneously to the redemption or defeasance of any equal principal amount of 2008KT Bonds in accordance with the Bond Indenture.

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

registered Holders and owners of this Note and of any Note issued in exchange hereof or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Note.

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

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

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

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

     Prior to due presentment for registration of transfer of this Note, the Company, the Trustee, any Paying Agent and any Note Registrar may deem and treat the registered Holder hereof as the absolute owner hereof (whether or not this Note shall be overdue and notwithstanding any notice of ownership or writing hereon made by anyone other than the Note Registrar) for the purpose of receiving payment of or on account of the principal hereof and

interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any Paying Agent nor any Security Registrar shall be affected by any notice to the contrary.

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

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

     IN WITNESS WHEREOF, the parties hereto have caused this Note to be duly executed and attested, all as of the day and year first above written.
