Liability”) that may result in a
Loss, the Indemnitee shall give notice thereof (the
“Claims Notice”) to any other party
obligated to provide indemnification pursuant to Section 5.1 or

pay, compromise or defend such Asserted Liability. Notwithstanding the foregoing,

over the objection of the other; provided, however, that consent to settlement
or
compromise shall not be unreasonably withheld. In any event, the
Indemnitee and the
Indemnifying Party may participate, at their own expense, in the defense of any such
Asserted Liability. If the Indemnifying Party chooses to defend any claim, the
Indemnitee
shall make available to the Indemnifying Party any books, records or
other documents
within its control that are necessary or appropriate for such defense.

      
    (3) Limitations on Liability;
Payments. The aggregate liability
of the Transferor for indemnification under this Section 5 and for all breaches of its
representations or warranties expressly set forth herein shall be limited to
$12,000,000.

funds, without set-off.

                                   ARTICLE TWO

                        TITLE AND TERMS OF THE SECURITIES

     SECTION 2.01. Title of the Securities; Stated Maturity. This Eighteenth
Supplemental Indenture hereby establishes one series of Securities, which shall
be known as the Company's "2005 Series C 5.19% Senior Notes due October 1, 2023"
(the "5.19% Notes" or 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 October 1,
2023.

     The Securities issued on the Original Issue Date will be sold by the
Company pursuant to the Purchase 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), Sections 301(a)(v), (ix), (x) and (xi),
Sections 301(b)(ii) and (iii), Section 301(d), and Sections 601(4) and (8),
subject, in each case, to the release provisions provided for in Section 4.02
herein. In addition, on and after the Release Date, unless Substitute Mortgage
Bonds are issued to secure the Notes, the Notes shall have the benefit of the
additional covenants set forth in Article Three hereof.

     (b) Section 503 of the Original Indenture shall apply to the Notes. The
following shall be an additional condition to defeasance of the Notes under
Section 503: the Company shall have delivered to the Trustee an Opinion of
Counsel stating that (i) the Company has received from the Internal Revenue
Service a letter ruling, or there has been published by the Internal Revenue

                                        4

<PAGE>

Service a Revenue Ruling, or (ii) since the date of execution of this Eighteenth
Supplemental Indenture, there has been a change in the applicable U.S. Federal
income tax law, in either case to the effect that, the Holders of such
Outstanding Notes appertaining thereto will not recognize income, gain or loss
for U.S. Federal income tax purposes as a result of such defeasance and will be
subject to U.S. Federal income tax on the same amounts, in the same manner and
at the same times as would have been the case if such defeasance had not
occurred, and, also, to the effect that, after the 123rd day after the date of
deposit, all money and other property as provided pursuant to Section 503 of the
Original Indenture (including the proceeds thereof) deposited or caused to be
deposited with the Trustee (or other qualifying trustee) pursuant to Section 503
of the Original Indenture to be held in trust will not be subject to any case or
proceeding (whether voluntary or involuntary) in respect of the Company under
any Federal or State bankruptcy, insolvency, reorganization or other similar
law, or any decree or order for relief in respect of the Company issued in
connection therewith.

     SECTION 2.03. Amount and Denominations. The aggregate principal amount of
Notes that may be issued under this Eighteenth Supplemental Indenture is limited
to $100,000,000 (except, in each case, 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.

     SECTION 2.04. Transfer and Exchange.

     (a) Transfer and Exchange of Definitive Securities. When Registered
Securities are presented to the Security Registrar with a request:

          (i) to register the transfer of such Registered Securities; or

          (ii) to exchange such Registered Securities for Registered Securities
     of the same series of any authorized denominations of the same aggregate
     principal amount and Stated Maturity, the Security Registrar shall register
     the transfer or make the exchange as requested if its reasonable
     requirements for such transaction are met; provided, however, that the
     Registered Securities surrendered for transfer or exchange:

               (A) shall be duly endorsed or be accompanied by a written
          instrument of transfer in form reasonably satisfactory to the Company
          and the Security Registrar, duly executed by the Holder thereof or his
          attorney duly authorized in writing; and

               (B) are accompanied by the following additional information and
          documents, as applicable:

                    (x) if such Registered Securities are being delivered to the
               Security Registrar by a Holder for registration in the name of
               such Holder, without transfer, a certification from such Holder
               to that effect (in the form set forth on the reverse side of the
               Transfer Restricted Security); or

                                        5

<PAGE>

                    (y) if such Registered Securities are being transferred to
               the Company, a certification to that effect (in the form set
               forth on the reverse side of the Transfer Restricted Security);
               or

               (C) if such Registered Securities are being transferred pursuant
          to an exemption from registration in accordance with Rule 144 under
          the Securities Act or in reliance upon another exemption from the
          registration requirements of the Securities Act, (i) a certification
          to that effect (in the form set forth on the reverse side of the
          Transfer Restricted Security) and (ii) if the Company so requests,
          other evidence reasonably satisfactory to it as to the compliance with
          the restrictions set forth in the legend set forth in Section 2.04(b).

     In case of redemption, the Company shall not be required (i) to issue,
register the transfer of or exchange Securities of any series during a period
beginning at the opening of business 15 days before any selection of 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, or (ii) to register the
transfer of or exchange any Registered Security so selected for redemption, in
whole or in part, except the unredeemed portion of any Security being redeemed
in part.

     (b) Legends for Securities. Each Security certificate evidencing the Notes
(and all Securities issued in exchange therefor or in substitution thereof)
shall bear a legend in substantially the following form (each defined term in
the legend being defined as such for purposes of the legend only):

     THE NOTES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
     ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") AND MAY NOT BE OFFERED,
     SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT (A) PURSUANT TO AN EXEMPTION
     FROM REGISTRATION UNDER THE SECURITIES ACT AND (B) IN ACCORDANCE WITH ALL
     APPLICABLE SECURITIES LAWS OF THE STATES OF THE UNITED STATES. IN
     CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE REGISTRAR AND
     TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS SUCH TRANSFER
     AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE
     FOREGOING RESTRICTIONS.

     SECTION 2.05. Certain Terms of the Notes.

     (a) The 5.19% Notes shall bear interest at the rate of 5.19% per annum on
the principal amount thereof from the date of original issuance, 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 Make-Whole Amount and (to the extent that payment of
such interest is enforceable under applicable law) on any overdue installment of
interest at the rate of 5.19% per annum during such overdue period. Interest on
the Notes will be payable semi-annually in arrears on October 1 and April 1 of
each year (each such date, an "Interest Payment Date"), commencing April 1,
2006. The amount of interest payable for any period shall be computed on the
basis of a 360-day year and twelve 30-day months.

                                        6

<PAGE>

     (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 fifteenth calendar day (whether or not a Business Day) prior
to the relevant Interest Payment Date (the "Regular Record Date"). Any such
interest installment not punctually paid or duly provided for shall forthwith
cease to be payable to the registered Holders on such Regular Record Date, and
may be paid to the person in whose name the Note (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date to
be fixed by the Trustee for the payment of such defaulted interest, notice
whereof shall be given to the registered Holders of the applicable Notes not
less than ten days prior to such Special Record Date. The principal of, and
Make-Whole Amount, if any, and the interest on the Notes shall be payable at the
office or agency of the Company maintained for that purpose in the Borough of
Manhattan, the City of New York, in any coin or currency of the United States of
America that at the time of payment is legal tender for payment of public and
private debts; provided, however, that payment of interest may be made at the
option of the Company by check mailed to the registered Holder at the close of
business on the Regular Record Date at such address as shall appear in the
Security Register. Notwithstanding the foregoing, so long as any Note is held by
an Institutional Investor, payment on the Notes held by such Holder shall be
made in the manner specified in the Purchase Agreement.

     (c) The Notes are not subject to repayment at the option of the Holders
thereof and are not subject to any sinking fund. As provided in the form of
Notes attached hereto as Exhibit A, the Notes are subject to optional
redemption, as a whole or in part, by the Company prior to Stated Maturity of
the principal thereof on the terms set forth therein. Except as modified in the
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 Eighteenth Supplemental Indenture as if set
forth in full at this place).

     SECTION 2.06. Form of Note. Attached hereto as Exhibit A is the form of the
definitive 5.19% Note. If the Company elects to have the Notes secured by
Substitute Mortgage Bonds on and after the Release Date, the terms of such 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.

                              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,

                                        8

<PAGE>

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

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

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

                                  ARTICLE FOUR

                         SECURITY AND RELEASE PROVISIONS

     SECTION 4.01. Security. Subject to Section 4.02 below, as provided in and
pursuant to Article Four of the Original Indenture, the Notes will be secured as
to payments of principal, interest and Make-Whole Amount, if any, by a series of
Mortgage Bonds (the "General and Refunding Mortgage Bonds, 2005 Series C",
singly or collectively, the "Bonds," the "Bonds of the related series" or the
"related series of Bonds") of the Company to be issued concurrently with the
issuance of the Notes under and secured by a Mortgage and Deed of Trust, dated
as of October 1, 1924, between the Company and J.P. Morgan Trust Company,
National Association, as successor trustee (the "Mortgage Trustee"), as amended
and supplemented by various supplemental indentures, including the supplemental
indenture, dated as of September 15, 2005, creating the Bonds (collectively, the
"Mortgage"), pledged by the Company for the benefit of the Holders of the Notes
to the Trustee under this Eighteenth Supplemental Indenture. The Bonds shall be
issued in an aggregate principal amount equal to the aggregate principal amount
of the Notes.

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

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

     Notwithstanding anything in the Original Indenture to the contrary, from
and after the Release Date, the obligation of the Company to make payment with
respect to the principal of and Make-Whole Amount, if any, and interest on the
Bonds shall be deemed satisfied and discharged as provided in the supplemental
indenture or indentures to the Mortgage creating such Bonds and the Bonds shall
cease to secure in any manner Notes theretofore or subsequently issued; the
Trustee shall thereupon surrender the Bonds to the Mortgage Trustee for
cancellation and execute and deliver such proper instruments of release as may
be required. From and after the Release Date, all Notes, whether theretofore or
subsequently issued, shall, at the Company's option, either

                                       10

<PAGE>

(i) become unsecured or (ii) be secured by Substitute Mortgage Bonds pursuant to
Section 4.03 below, and any conditions to the issuance of Notes that refer or
relate to Bonds or the Mortgage shall be inapplicable (except as such conditions
shall be deemed to refer to Substitute Mortgage Bonds or a Substitute Mortgage
pursuant to Section 4.03 below). From and after the Release Date, the Company
shall not issue any additional Mortgage Bonds, including Pledged Bonds, under
the Mortgage. Notice of the occurrence of the Release Date shall be given by the
Trustee to the Holders of the Notes in the manner provided for in the Original
Indenture not later than 30 days after the Company notifies the Trustee of the
occurrence of the Release Date.

     In connection with the establishment of the occurrence of the Release Date,
the Trustee shall be entitled to receive, may presume the correctness of, and

Securities subject to the release provisions when and as the same shall become
due and payable in accordance with the terms and provisions of the Original

series or issue of Substitute Mortgage Bonds having the same stated rate or
rates of interest (or interest calculated in the same manner), Interest Payment
Dates, stated maturity date and redemption provisions, and in the same aggregate
principal amount, as the related series or issue of Notes or other Securities
subject to the release provisions outstanding on the Release Date. The Company

Section 4.03(a), the Notes and other Securities subject to the release
provisions Outstanding on the Release Date shall, as of the Release Date, no
longer be entitled to the benefit of the pledge of the Pledged Bonds and shall
thereafter be general unsecured obligations of the Company.

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

Mortgage; or".

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

     THE DETROIT EDISON COMPANY, a corporation duly organized and existing under

received, hereby promises to pay to _______________, or registered assigns, at
the office or agency of the Company in The City of New York, New York, the

installment of interest. The interest installment 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. 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

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 Holders of Notes of this series not
less than ten days prior to such Special Record Date.

excluding the respective Interest Payment Dates. Interest payments for this Note
shall be computed and paid on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal and Make-Whole
Amount, 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, Make-Whole Amount, 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 other than a
day on which banking institutions in the State of New York or the State of
Michigan are authorized or obligated pursuant to law or executive order to
close.

     Payment of principal of, Make-Whole Amount, 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, Make-Whole Amount, if any, and interest due at the Stated
Maturity or earlier redemption of the Notes shall be made at the office of the
Paying Agent upon surrender of such Securities to the Paying Agent, and (ii)
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.
Notwithstanding the foregoing, so long as any Note is held by an Institutional
Investor, payment of principal, Make-Whole Amount, if any, and interest on the
Notes held by such Holder shall be made in the manner specified in the Purchase
Agreement.

     UNTIL THE RELEASE DATE (AS DEFINED BELOW), THIS NOTE SHALL BE SECURED BY
GENERAL AND REFUNDING MORTGAGE BONDS, 2005 SERIES C (THE "MORTGAGE BONDS")
ISSUED AND DELIVERED BY THE COMPANY TO THE TRUSTEE (AS DEFINED BELOW) UNDER THE
COMPANY'S SUPPLEMENTAL INDENTURE DATED AS OF SEPTEMBER 15, 2005, SUPPLEMENTING

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.

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

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

     This Note is one of a duly authorized series of Securities of the Company
(herein sometimes referred to as the "Notes"), specified in the Indenture, all
issued or to be issued in one or more series under and pursuant to a Collateral
Trust Indenture dated as of June 30, 1993 (the "Original Indenture") duly
executed and delivered between the Company and the trustee named therein (now
J.P. Morgan Trust Company, National Association, as successor trustee) (herein
referred to as the "Trustee"), as supplemented through and including an
Eighteenth Supplemental Indenture dated as of September 15, 2005 (together with
the Original Indenture, the "Indenture") between the Company and the Trustee, to
which Indenture and all indentures supplemental thereto reference is hereby made
for a description of the respective rights, limitations of rights, obligations,
duties and immunities thereunder of the Trustee, the Company and the registered
Holders of the Notes and of the terms upon which the Notes are, and are to be,
authenticated and delivered.

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

     This Note will be redeemable at the option of the Company, in whole at any
time or in part from time to time (any such date of optional redemption, an
"Optional Redemption Date," which shall be a "Redemption Date" for purposes of
the Indenture), at an optional redemption price (which shall be a "Redemption
Price" for purposes of the Indenture) equal to 100% of the principal amount of
this Note to be redeemed together with the Make-Whole Amount (as defined below),
if any, plus, in each case, accrued and unpaid interest thereon to the
Redemption Date.

     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.

     "Make-Whole Amount" means, with respect to any Note, an amount equal to the
excess, if any, of the Discounted Value of the Remaining Scheduled Payments with
respect to the Called Principal of such Note over the amount of such Called
Principal, provided that the Make-Whole Amount may in no event be less than
zero. For the purposes of determining the Make-Whole Amount, the following terms
have the following meanings:

                                       A-3

<PAGE>

     "Called Principal" means, with respect to a Note, the principal of the Note
that is to be redeemed on an Optional Redemption Date or has become or is
declared to be immediately due and payable pursuant to Section 602 of the
Indenture, as the context requires.

     "Discounted Value" means, with respect to the Called Principal of a Note,
the amount obtained by discounting all Remaining Scheduled Payments with respect
to such Called Principal from their respective scheduled due dates to the
Settlement Date with respect to such Called Principal, in accordance with
accepted financial practice and at a discount factor (applied on the same
periodic basis as that on which interest on the Note is payable) equal to the
Reinvestment Yield with respect to such Called Principal.

     "Reinvestment Yield" means, with respect to the Called Principal of a Note,
0.20% plus the yield to maturity implied by (i) the yields reported, as of 10:00
a.m. (New York City time) on the second Business Day preceding the Settlement
Date with respect to such Called Principal, on the display designated as "PX-1"
on the Bloomberg Financial Market Screen (or such other display as may replace
"PX-1" on the Bloomberg Financial Market Screen) for actively traded U.S.
Treasury securities having a maturity equal to the Remaining Average Life of
such Called Principal as of such Settlement Date, or (ii) if such yields are not
reported as of such time or the yields reported as of such time are not
ascertainable, the Treasury Constant Maturity Series Yields reported, for the
latest day for which such yields have been so reported as of the second Business
Day preceding the Settlement Date with respect to such Called Principal, in
Federal Reserve Statistical Release H.15 (519) (or any comparable successor
publication) for actively traded U.S. Treasury securities having a constant
maturity equal to the Remaining Average Life of such Called Principal as of such
Settlement Date. Such implied yield will be determined, if necessary, by (a)
converting U.S. Treasury bill quotations to bond-equivalent yields in accordance
with accepted financial practice and (b) interpolating linearly on a straight
line basis between (1) the actively traded U.S. Treasury security with the
maturity closest to and greater than the Remaining Average Life and (2) the
actively traded U.S. Treasury security with the maturity closest to and less
than the Remaining Average Life.

     "Remaining Average Life" means, with respect to any Called Principal, the
number of years (calculated to the nearest one-twelfth year) obtained by
dividing (i) such Called Principal into (ii) the sum of the products obtained by
multiplying (a) the principal component of each Remaining Scheduled Payment with
respect to such Called Principal by (b) the number of years (calculated to the
nearest one-twelfth year) that will elapse between the Settlement Date with
respect to such Called Principal and the scheduled Redemption Date of such
Remaining Scheduled Payment.

     "Remaining Scheduled Payments" means, with respect to the Called Principal
of a Note, all payments of such Called Principal and interest thereon that would
be due after the Settlement Date with respect to such Called Principal if no
payment of such Called Principal were made prior to its scheduled Redemption
Date, provided that if such Settlement Date is not a date on which interest
payments are due to be made under the terms of the Note, then the amount of the
next succeeding scheduled interest payment will be reduced by the amount of
interest accrued to such Settlement Date and required to be paid on such
Settlement Date.

                                       A-4

<PAGE>

          "Settlement Date" means, with respect to the Called Principal of a
     Note, the Optional Redemption Date on which such Called Principal is to be
     redeemed or has become or is declared to be immediately due and payable
     pursuant to Section 602 of the Indenture as the context requires.

     Notice of any optional redemption will be mailed at least 30 days but not
more than 60 days before the Optional Redemption Date to the Holder hereof at
its registered address. Each such notice shall specify such Optional Redemption
Date, the aggregate principal amount of the Notes to be prepaid on such date,
the principal amount of each Note held by such Holder to be redeemed, and the
interest to be paid on the Redemption Date with respect to such principal amount
being prepaid, and shall be accompanied by a certificate of a senior financial
officer of the Company as to the estimated Make-Whole Amount due in connection
with such redemption (calculated as if the date of such notice were the date of
the redemption), setting forth the details of such computation. The Make-Whole
Amount shall be determined by the Company two Business Days prior to the
applicable Redemption Date and the Company shall deliver to holder of the Notes
and to the Trustee a certificate of a senior financial officer specifying the
calculation of such Make-Whole Amount as of the Redemption Date.

     If notice has been provided in accordance with the Indenture and funds for
the redemption of this Note called for redemption have been made available on
the Redemption Date, this Note will cease to bear interest on the date fixed for
redemption. Thereafter, the only right of the Holder hereof will be to receive
payment of the Redemption Price.

     The Company 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 the Redemption Date. 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 pro rata
among all of the Notes at the time outstanding in proportion, as nearly as
practicable, to the respective unpaid principal amounts thereof and otherwise in
accordance with the terms of the Indenture. Upon any such declaration, the
Company shall also pay to the Holders of the Notes the Make-Whole Amount on the
Notes, if any, determined as of the date the Notes shall have been declared due
and payable.

     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. Upon any such
declaration, the Company shall also pay to the Holders of the Notes the
Make-Whole Amount on the Notes, if any, determined as of the date the Notes
shall have been declared due and payable.

                                       A-5

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

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

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of, Make-Whole Amount, if any,
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 Security Registrar may deem and
treat the registered Holder hereof as the absolute owner hereof (whether or not

any Paying Agent nor any Security Registrar shall be affected by any notice to
the contrary.

registered Holder surrendering the same.

     As set forth in, and subject to the provisions of, the Indenture, no Holder
of any Note will have any right to institute any proceeding with respect to the
Indenture or for any remedy thereunder, unless (i) such Holder shall have
previously given to the Trustee written notice of a continuing Event of Default
with respect to the Notes of this series, (ii) the Holders of not less than 25%
in principal amount of the outstanding Notes of this series shall have made
written request, and offered reasonable indemnity, to the Trustee to institute
such proceeding as trustee, (iii) the Trustee shall have failed to institute
such proceeding within 60 days and (iv) the Trustee shall not have received from
the Holders of a majority in principal amount of the outstanding Notes of this

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.
