ARTICLE I

SERIES FFF BONDS

Section 1: There is hereby created, for issuance under the Original Indenture as supplemented by the said Supplemental Indentures (including this Fifty-Fourth Supplemental Indenture), a series of bonds designated Series FFF, due 2037, each of which shall bear the descriptive title “First Mortgage Bonds, Series FFF, due 2037” (herein sometimes referred to as “Series FFF Bonds”), and the form thereof shall contain suitable provisions with respect to the matters hereinafter in this Section specified. The Series FFF Bonds shall mature on September 15 , 2037 and shall be issued in denominations of $1,000 and integral multiples thereof as the Company may from time to time execute and deliver. The Series FFF Bonds shall bear interest at the rate and from the date, shall be expressed to mature as to principal, and shall be payable as to principal and interest at such place or places and in such money, all as provided in the form of Series FFF Bond set forth on Exhibit A hereto (the “Form of Bond”) and by the applicable provisions of the Indenture. In addition, September 20, 2007 shall be an Interest Payment Date for the Series FFF Bonds for purposes of Section 9 of Article II of the Indenture, provided that no interest shall be payable on such date. Both the principal and interest on the Series FFF Bonds shall be payable at the corporate trust office of the Trustee in the City and County of San Francisco, State of California. The Series FFF Bonds shall be dated as in Section 9 of Article II of the Indenture provided with respect to registered bonds without coupons.

The Series FFF Bonds shall further be redeemable, exchangeable, transferable and otherwise have the terms set forth in the Form of Bond.

The Series FFF Bonds shall otherwise be of such terms, provisions, tenor and form as provided in this Fifty-Fourth Supplemental Indenture.

Section 2: The Series FFF Bonds shall be executed, authenticated and delivered in accordance with the provisions and shall be entitled to the protection and security, of the Original Indenture supplemented by this Fifty-Fourth Supplemental Indenture and the other supplemental indentures, and shall be subject to all of the terms, conditions and covenants and limitations thereof. The aggregate principal amount of the Series FFF Bonds, which may be executed by the Company and authenticated and delivered by the Trustee and secured by the Indenture as from time to time in effect, is limited only to the extent provided in Section 1 of Article II of the Original Indenture.

Section 3: The Series FFF Bonds shall be issued only as fully registered bonds without coupons. The fully registered bonds without coupons and the certificate of authentication to be endorsed on all Series FFF Bonds shall be substantially in the form set forth on the Form of Bond. In addition, the Series FFF Bonds may be issuable in whole or in part in the form of one or more securities that evidences all or part of the bonds of such series which is issued to a depository or a nominee thereof for such series (a “Global Security”) and, in such case, the Board of Directors of the Company shall appoint a clearing agency registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), designated to act as depositary (a “depositary”) for such Global Securities. The definitive Series FFF Bonds shall be numbered in such manner as the Company shall at any time or from time to time determine.

Section 4: In the event the Series FFF Bonds are issued as a Global Security the following provisions, in addition to the provisions of the Indenture, shall apply:

(1) Each Global Security authenticated under the Indenture shall be registered in the name of the depositary designated for such Global Security or a nominee thereof and delivered to such depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single bond for all purposes of this Supplemental Indenture.

(2) Notwithstanding any other provision in this Supplemental Indenture, no Global Security may be exchanged in whole or in part for bonds registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any person other than the depositary for such Global Security or a nominee thereof unless (A) such depositary has notified the Company that it is unwilling or unable to continue as depositary for such Global Security and a successor depositary has not been appointed by the Company within 90 days of receipt by the Company of such notification, (B) if at any time the depositary ceases to be a clearing agency registered under the Exchange Act at a time when the depositary is required to be so registered to act as such depositary and no successor depositary shall have been appointed by the Company within 90 days after it became aware of such cessation, (C) the Company, in its sole discretion, executes and delivers to the Trustee a written order signed in the name of the Company by its Chairman of the Board, its President or a Vice President, and by its Treasurer, an Assistant Treasurer, its Secretary or an Assistant Secretary to the effect that such Global Security, together with all other Global Securities of the same series, shall be exchangeable as described below, or (D) a “completed default” (as defined in the Indenture) has occurred and is continuing with respect to the Series FFF Bonds. If any of the events described in clauses (A) through (D) of the preceding sentence occur, the beneficial owners of interests in the relevant Global Securities will be entitled to exchange those interests for definitive bonds and, without unnecessary delay but in any event not later than the earliest date on which those interests may be so exchanged, the Company will deliver to the Trustee definitive bonds in such form and denominations as are required by or pursuant to this Indenture, and of the same series, containing identical terms and in an aggregate principal amount equal to the principal amount of such Global Securities, such bonds to be duly executed by the Company. On or after the earliest date on which such beneficial interests may be so exchanged, such Global Securities shall be surrendered from time to time by the depositary as shall be specified in the order from the Company with respect thereto (which the Company agrees to deliver), and in accordance with any instructions given to the Trustee and the depositary (which instructions shall be in writing but need not be contained in or accompanied by an officers’ certificate or be accompanied by an opinion of counsel), as shall be specified in the order from the Company with respect thereto to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or in part, for definitive bonds as described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of such surrendered Global Security, a like aggregate principal amount of definitive bonds of the same series of authorized denominations and of like tenor as the portion of such Global Security to be exchanged. Promptly following any such exchange in part, such Global Security shall be returned by the Trustee to such depositary or its custodian. If a definitive bond is issued in exchange for any portion of a Global Security after the close of business at the place where such exchange occurs on or after (i) any regular record date for the date the interest is due (the “Interest Payment Date”) for such bond and before the opening of business at that place of payment on the next Interest Payment Date, or (ii) any special record date for the payment of interest for such bond and before the opening of business at such place of payment on the related proposed date for the payment of the interest which was not punctually paid or duly provided for on any Interest Payment Date, as the case may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such definitive bond, but shall be payable on the Interest Payment Date or proposed date for payment, as the case may be, only to the person to whom interest in respect of such portion of such Global Security shall be payable in accordance with the provisions of this Indenture.

(3) Subject to Clause (2) above, any exchange or transfer of a Global Security for other bonds may be made in whole or in part, and all bonds issued in exchange for or upon transfer of a Global Security or any portion thereof shall be registered in such names as the depositary for such Global Security shall direct.

(4) Every bond authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such bond is registered in the name of a person other than the depositary for such Global Security or a nominee thereof.

(5) Unless otherwise specified as contemplated by Section 1 of Article I of this Supplemental Indenture for the bonds evidenced thereby, every Global Security authenticated and delivered hereunder shall bear a legend in substantially the following form:

THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART FOR A SECURITY REGISTERED, AND NO TRANSFER OF THIS SECURITY IN WHOLE OR IN PART MAY BE REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH DEPOSITARY OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE. ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF HAS AN INTEREST HEREIN.

Section 5: The Series FFF Bonds may contain or have imprinted thereon such provisions or specifications not inconsistent with the Indenture as may be required to comply with the rules of any stock exchange or any federal or state authority or commission, or to comply with usage with respect thereto, and may bear such other appropriate endorsements or notations as are authorized or permitted by the Indenture.

Section 6: In the manner and subject to certain conditions and limitations specified herein and in the Indenture, Series FFF Bonds may be exchanged without a service charge for a like aggregate principal amount of such Series FFF Bonds of other authorized denomination or denominations; provided that the Company may require payment of a sum or sums sufficient to reimburse it for any stamp tax or other governmental charge payable in connection therewith.

Section 7: The Company shall maintain in the City and County of San Francisco, State of California, and in such other place or places as the Company may designate at any time or from time to time, an office or agency where Series FFF Bonds may be presented for payment, registration, transfer and exchange as provided therein or in the Indenture. Such office or agency in the City and County of San Francisco shall be the corporate trust office of the Trustee unless and until the Company shall designate another office or agency by notice in writing delivered to the Trustee. Notwithstanding the foregoing, if and when definitive bonds are issued, the Company shall maintain in the Borough of Manhattan, City and County of New York, State of New York, an office or agency where Series FFF Bonds may be presented for payment, registration, transfer and exchange as provided therein or in the Indenture.

Section 8: No transfer or exchange of any Series FFF Bonds pursuant to any of the provisions of this Article I shall be made except upon and in accordance with all of the applicable terms, provisions and conditions of said bonds and of the Indenture.

ARTICLE II

This bond is one of a duly authorized issue of bonds of the Company, known as its First Mortgage Bonds, of the series and designation indicated on the face hereof (the “Series FFF Bonds”), all issued and to be issued under and equally secured by a Mortgage and Deed of Trust dated July 1, 1940, and indentures supplemental thereto, including the Fifty-Fourth Supplemental Indenture dated as of September 20, 2007 (which Mortgage and Deed of Trust, as so supplemented, is herein called the “Indenture”) executed by the Company to U.S. Bank National Association, as Trustee (herein called the “Trustee”), to which Indenture reference is hereby made for a description of the property mortgaged, pledged, hypothecated and in which a security interest was granted, the nature and extent of the security, the rights of the holders of the Series FFF Bonds as to such security, and the terms and conditions upon which the Series FFF Bonds may be issued under the Indenture and are secured. The principal hereof may be declared or may become due on the conditions, in the manner and at the time set forth in the Indenture, upon the happening of a completed default as in the Indenture provided.

With the consent of the Company and to the extent permitted by and as provided in the Indenture, the rights and obligations of the Company or of the holders of the Series FFF Bonds, or the terms and provisions of the Indenture or of any indentures supplemental thereto, may be modified or altered by the affirmative vote of the holders of the percentage of principal amount of bonds required by the Indenture; provided, however, that without the consent of the holder hereof no such modification or alteration shall permit the reduction of the principal or the extension of the maturity of the principal of this bond, or the reduction of the rate of interest hereon, or any other modification of the terms of payment of such principal or interest.

The Company, the Trustee, any paying agent, any registrar, and any depositary may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment of or on account of the principal hereof and interest hereon and for all other purposes and shall not be affected by any notice to the contrary.

All or a portion of the Series FFF Bonds may be redeemed at the Company’s option at any time or from time to time.

The price at which the Series FFF Bonds will be redeemed (the “Redemption Price”) on the date fixed for such redemption (the “Redemption Date”) will be equal to the greater of the following amounts: (a) 100% of the principal amount of the Series FFF Bonds being redeemed on the Redemption Date; or (b) the sum of the present values of the remaining scheduled payments of principal and interest on the Series FFF Bonds being redeemed on that Redemption Date (not including any portion of any payments of accrued and unpaid interest to the Redemption Date) discounted to the Redemption Date on a semiannual basis at the Adjusted Treasury Rate (as defined below) plus 25 basis points, as determined by the Reference Treasury Dealer (as defined below), plus, in each case, accrued and unpaid interest thereon to the Redemption Date. Notwithstanding the foregoing, installments of interest on Series FFF Bonds 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 of such Series FFF Bonds as of the close of business on the relevant record date. The Redemption Price will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

As more fully provided in and subject to the provisions of the Indenture, the Series FFF Bonds are also subject to redemption on any date, under certain circumstances specified in Section 13 of Article XI of the Indenture in case of the disposition of certain properties of the Company, at 100% of the principal amount thereof, together with accrued interest thereon.

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each registered holder of the Series FFF Bonds to be redeemed. Once notice of redemption is mailed, the Series FFF Bonds called for redemption will become due and payable on the Redemption Date and at the applicable Redemption Price, plus accrued and unpaid interest to the Redemption Date. Redemption will not be conditional upon receipt by the Trustee of monies sufficient to pay the Redemption Price.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Series FFF Bonds or portions thereof called for redemption. The Company will pay the Redemption Price and any accrued interest once the Series FFF Bonds are surrendered for redemption. If only a portion of the Series FFF Bonds are redeemed, the Trustee will deliver new Series FFF Bonds for the remaining portion without charge.

“Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Reference Treasury Dealer as having a maturity comparable to the remaining term of the Series FFF Bonds to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Series FFF Bonds.

“Comparable Treasury Price” means, with respect to any Redemption Date, (A) the average of the Reference Treasury Dealer Quotations for such Redemption Date, or (B) if only one Reference Treasury Dealer Quotation is received, such Quotation.

“Reference Treasury Dealer” means (A) Deutsche Bank Securities Inc., Xxxxxxx Lynch, Pierce, Xxxxxx & Xxxxx Incorporated and Xxxxxx Xxxxxxx & Co. Incorporated (or their affiliates which are Primary Treasury Dealers) and their successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”), the Company will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Company.

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

In the event that the Company elects to redeem only a portion of the Series FFF Bonds, the bonds to be redeemed shall be selected in accordance with the procedures of The Depository Trust Company, in the case of bonds represented by a global security, or by the Trustee by a method the Trustee deems to be fair and appropriate, in the case of bonds that are not represented by a global security.

This bond is transferable as prescribed in the Indenture by the registered owner hereof in person, or by his duty authorized attorney, at the corporate trust office of the Trustee in the City and County of San Francisco, State of California, upon surrender and cancellation of this bond and thereupon a new registered bond of the same series and principal amount will be issued to the transferee in exchange therefor as provided in the Indenture, upon payment of any tax or taxes or other governmental charges required to be paid by the Company by reason of such transfer.

The registered owner of any Series FFF Bond, at the option of such holder, may surrender the same, accompanied by a written instrument of transfer in form approved by the Company duly executed by the registered owner, at the corporate trust office of the Trustee in the City and County of San Francisco, State of California, for cancellation in exchange for another or other registered bonds of the said series of higher or lower authorized denominations of an aggregate principal amount equal to the aggregate principal amount of the bond or bonds so surrendered and bearing interest as provided in Section 9 of Article II of the Indenture, and upon payment of any tax or taxes or other governmental charges required to be paid by the Company by reason of such exchange and subject to the terms and conditions specified in the Indenture, thereupon the Company shall execute and deliver to the Trustee and the Trustee shall authenticate and deliver such other bonds to such registered owner at its office or at such agency of the Company, at the option of such registered owner.

No recourse shall be had for the payment of the principal of (or premium, if any) or the interest on this bond, or any part thereof, or of any claim based herein or in respect hereof or of said Indenture, against any incorporator, or any past, or future stockholder, officer or director, as such, of the Company or of any predecessor or successor corporation, either directly or through the Company, or through any such predecessor or successor corporation, or through any receiver or a trustee in bankruptcy, whether, by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof expressly waived and released, as more fully provided in the Indenture.
