Payments of interest on this Bond will include interest accrued to but excluding the respective Interest Payment Dates. In the event that any Interest Payment Date is not a Business Day (other than an Interest Payment Date that falls on the Maturity Date), then such Interest Payment Date will be postponed to the next succeeding day that is a Business Day unless the Interest Payment Date falls in the next succeeding calendar month in which case the Interest Payment Date will be the immediately preceding Business Day.

Dated: ________________ PACIFIC GAS AND ELECTRIC COMPANY By ____________________________________ By ____________________________________ B-4 TRUSTEE'S CERTIFICATE OF AUTHENTICATION This is one of the Bonds of the series designated as Bonds of the Fifth Series referred to in the within-mentioned Indenture. ______________________________________, As Trustee By_____________________________________ Authorized Signatory B-5 [FORM OF REVERSE OF BOND] This Floating Rate First Mortgage Bond due 2006 is one of a duly authorized issue of Bonds of the Company (the "Bonds"), issued and issuable in one or more series under [and equally secured by] an Indenture of Mortgage, dated as of March 11, 2004 (such Indenture as originally executed and delivered and as supplemented or amended from time to time thereafter, together with any constituent instruments establishing the terms of particular Bonds, being herein called the "Indenture"), between the Company and BNY Western Trust Company, as Trustee (herein called the "Trustee," which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a description of [the property mortgaged, pledged and held in trust, the nature and extent of the security and] the respective rights, limitations of rights, duties and immunities of the Company, the Trustee and the Holders of Bonds thereunder and of the terms and conditions upon which Bonds are, and are to be, authenticated and delivered. The acceptance of this Bond shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. The interest rate on this Bond will be reset quarterly on each Interest Payment Date (each an "Interest Reset Date"); provided, however, that the interest rate in effect from the Original Issue Date stated above to July 3, 2004 will be the Initial Interest Rate specified on the face hereof. If any Interest Reset Date would otherwise be a day that is not a Business Day, the Interest Reset Date shall be postponed to the next day that is a Business Day except that if such Business Day is in the next succeeding calendar month, such Interest Reset Date shall be the immediately preceding Business Day. Subject to applicable provisions of law, on each Interest Reset Date, the rate of interest on this Bond shall be determined in accordance with the following provisions: With respect to any Interest Determination Date (as defined below), LIBOR will be the rate for deposits in U.S. Dollars having a maturity of three months for a period commencing on the second London Business Day immediately following such Interest Determination Date in amounts of not less than $1,000,000, as that rate appears on the display on Moneyline Telerate Page 3750 as of 11:00 a.m., London time, on such Interest Determination Date. "Moneyline Telerate Page 3750" means the display designated as page "3750" on Moneyline Telerate (or such other page as may replace the 3750 page on any successor service for the purpose of displaying London interbank rates of major banks for U.S. dollar deposits). If no rate appears on Moneyline Telerate Page 3750 at approximately 11:00 a.m., London time on an Interest Determination Date, the Calculation Agent will determine LIBOR in respect of such Interest Determination Date as follows: the Calculation Agent will request the principal London offices of each of four major reference banks in the London interbank market, as selected by the Calculation Agent (after consultation with the Company), to provide the Calculation Agent with its offered quotation for deposits in U.S. Dollars for the period of three months commencing on the second London Business Day immediately following such Interest Determination Date to prime banks in the London interbank market at approximately 11:00 a.m., London time, on such Interest Determination Date and in a principal amount equal to an amount not less than $1,000,000 that is representative of a single transaction in U.S. Dollars in such market at such time, and (a) if at least two such quotations are provided, LIBOR determined on such Interest Determination Date will be the arithmetic mean (rounded, if necessary, to the B-6 nearest one-hundred-thousandth of a percentage point (0.000001%), with five-millionths of a percentage point (0.0000005%) rounded upwards) of such quotations, or (b) if fewer than two quotations are provided, LIBOR determined on such Interest Determination Date will be the arithmetic mean (rounded, if necessary, to the nearest one-hundred-thousandth of a percentage point (0.000001%), with five-millionths of a percentage point (0.0000005%) rounded upwards) of the rates quoted at approximately 11:00 a.m., in The City of New York, on such Interest Determination Date, by three major banks in The City of New York selected by the Calculation Agent (after consultation with the Company) for loans in U.S. Dollars to leading European banks, having a maturity of three months commencing on the second London Business Day immediately following such Interest Determination Date and in a principal amount equal to an amount not less than $1,000,000 that is representative for a single transaction in U.S. Dollars in such market at such time; provided, however, that if the banks selected by the Calculation Agent are not providing quotations in the manner mentioned in this sentence, LIBOR will remain the LIBOR then in effect on such Interest Determination Date. Interest will be payable on January 3, April 3, July 3 and October 3 (each an "Interest Payment Date"), commencing on July 3, 2004, and at Maturity. If any Interest Payment Date would otherwise be a day that is not a Business Day, the Interest Payment Date shall be postponed to the next day that is a Business Day, except that if such Business Day is in the next succeeding calendar month, such Interest Payment Date shall be the immediately preceding Business Day. If the Maturity Date falls on a day that is not a Business Day, the payment of principal and interest may be made on the next succeeding Business Day, and no interest on such payment shall accrue for the period from and after maturity. "Business Day" means with respect to any Bond, any London Business Day except a Saturday, a Sunday or a legal holiday in The City of New York on which banking institutions are authorized or required by law, regulation or executive order to close. "London Business Day" means any day on which dealings in deposits in U.S. Dollars are transacted or, with respect to any future date, are expected to be transacted, in the London interbank market. The Interest Determination Date pertaining to an Interest Reset Date will be the second London Business Day preceding such Interest Reset Date. Unless otherwise specified on the face hereof, interest payments, if any, will be the amount of interest accrued from and including the last date in respect of which interest has been paid or duly provided for (or from and including the Original Issue Date stated above if no interest has been paid or provided for with respect to this Bond) to but excluding the Interest Payment Date or the date of Maturity. Accrued interest hereon from the Original Issue Date stated above or from the last date to which interest hereon has been paid is calculated by multiplying the face amount hereof by an accrued interest factor. Such accrued interest factor is computed by adding the interest factor calculated for each day from the Original Issue Date stated above or from the last date to which interest shall have been paid, to the date for which accrued interest is being calculated. The interest factor for each day shall be computed by dividing the interest rate applicable to such day by 360. All percentages resulting from any calculation hereon will be rounded to the nearest one hundred-thousandth of a percentage point, with five-one millionths of a percentage point rounded upwards. For example, 9.876545% (or B-7 ..09876545) would be rounded to 9.87655% (or .0987655). All dollar amounts used in or resulting from any calculation hereon will be rounded to the nearest cent. The interest rate on this Bond will in no event be higher than the maximum rate permitted by California law as the same may be modified by United States law of general applicability. The Calculation Agent will, upon the request of the Holder of this Bond, provide to such Holder the interest rate hereon then in effect and, if different, the interest rate which will become effective as a result of a determination made on the most recent Interest Determination Date. The Bonds of this series are subject to mandatory redemption ("Mandatory Redemption") in whole on June 23, 2004 (the "Mandatory Redemption Date"), in the event the Effective Date has not occurred on or before June 21, 2004, at a redemption price equal to the principal amount of the Bonds of this series plus a redemption premium of 1.00% on such principal amount, and accrued and unpaid interest from March 23, 2004 to but not including the Mandatory Redemption Date. Subject to the terms and conditions of the Indenture, the Bonds of this series are also redeemable at the option of the Company ("Optional Redemption"), in whole or in part, on October 3, 2004 and on any Interest Payment Date thereafter and prior to Maturity, at a Redemption Price equal to 100% of the principal amount of the Bonds of this series to be redeemed, plus accrued and unpaid interest on the principal amount of the Bonds of this series being redeemed to but not including the Redemption Date. Interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable to Holders of such Bonds, or one or more Predecessor Bonds, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture. In the case of a Mandatory Redemption, a conditional notice of Mandatory Redemption will be in writing and mailed first-class postage-prepaid not less than 7 days nor more than 30 days prior to the Mandatory Redemption Date, but only if the Effective Date has not occurred on or by such date of mailing, to each Holder of Bonds of this series at the Holder's registered address. If moneys are applied to effect a Mandatory Redemption on the Mandatory Redemption Date therefor, immediately after such Mandatory Redemption Date interest shall cease to accrue on such Bonds. In the case of an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 30 days nor more than 60 days prior to the Redemption Date to each Holder of Bonds of this series to be redeemed at the Holder's registered address. If money sufficient to pay the Redemption Price of all Bonds of this series (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent or the Trustee on or prior to the Redemption Date, from and after such Redemption Date such Bonds or portions thereof shall cease to bear interest. Bonds of this series in denominations larger than $1,000 in principal amount may be redeemed in part but only in integral multiples of $1,000. B-8 In the event of redemption of this Bond in part only, a new Bond or Bonds of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the surrender hereof. As provided in the Indenture and subject to certain limitations therein set forth, this Bond or any portion of the principal amount hereof will be deemed to have been paid for all purposes of the Indenture and to be no longer Outstanding thereunder, and the Company's entire indebtedness in respect thereof will be satisfied and discharged, if there has been irrevocably deposited with the Trustee or any Paying Agent (other than the Company), in trust, money in an amount which will be sufficient and/or Eligible Obligations, the principal of and interest on which when due, without regard to any reinvestment thereof, will provide moneys which, together with money, if any, deposited with or held by the Trustee or such Paying Agent, will be sufficient to pay when due the principal of and premium, if any, and interest on this Bond when due. If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than a majority, prior to the Release Date, or 33%, on or after the Release Date, in aggregate principal amount of the Outstanding Bonds, considered as one class, may declare the principal amount of all Bonds then Outstanding to be due and payable immediately by notice in writing to the Company (and to the Trustee if given by Holders); provided, however, that with respect to certain Events of Default relating to bankruptcy, insolvency and similar events, the principal amount of all Bonds then Outstanding shall be due and payable immediately without further action by the Trustee or the Holders. The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, the Indenture with the consent of the Holders of not less than a majority in aggregate principal amount of the Bonds at the time Outstanding, considered as one class; provided, however, that if there shall be Bonds of more than one series Outstanding under the Indenture and if a proposed supplemental indenture shall directly affect the rights of the Holders of Bonds of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Bonds of all series so directly affected, considered as one class, shall be required; and provided, further, that if the Bonds of any series shall have been issued in more than one Tranche and if a proposed supplemental indenture shall directly affect the rights of the Holders of Bonds of one or more, but less than all, of such Tranches, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Bonds of all Tranches so directly affected, considered as one class, shall be required; and provided, further, that the Indenture permits the Company and the Trustee to enter into one or more supplemental indentures for certain purposes without the consent of any Holders of Bonds. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of Bonds, on behalf of the Holders of all such Bonds, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Bond shall be conclusive and binding upon such Holder and upon all future Holders of this Bond and of any Bond issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Bond. B-9 As provided in and subject to the provisions of the Indenture, the Holder of this Bond shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default, the Holders of at least 33% in aggregate principal amount of the Bonds at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of at least a majority in aggregate principal amount of Bonds at the time Outstanding a direction inconsistent with such written request, and shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Bond for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein. No reference herein to the Indenture and no provision of this Bond or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Bond at the times, place and rate, and in the coin or currency, herein prescribed. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Bond is registrable in the Bond Register, upon surrender of this Bond for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Bond are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company, the Trustee or the Bond Registrar, as the case may be, duly executed by the Holder hereof or such Holder's attorney duly authorized in writing, and thereupon one or more new Bonds 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. The Bonds of this series are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Bonds of this series are exchangeable for a like aggregate principal amount of Bonds of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. The Company shall not be required to execute or to provide for the registration of the transfer of or the exchange of (A) any Bond of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of the Bonds of this series called for redemption, or (B) any Bond of this series selected for redemption in whole or in part, except the unredeemed portion of any Bond of this series being redeemed in part.

This Bond shall be governed by, and construed and enforced in accordance with, the laws of the State of California without regard to the principles of conflicts of laws thereunder, except to the extent that the Trust Indenture Act shall be applicable. As provided in the Indenture, no recourse shall be had for the payment of the principal of, premium, if any, or interest with respect to this Bond, or any part thereof, or for any claim based hereon or otherwise in respect hereof, or of the indebtedness represented hereby, or upon any obligation, covenant or agreement under the Indenture, against any incorporator, shareholder, officer or director, as such, past, present or future, of the Company or of any predecessor or successor corporation (either directly or through the Company or a predecessor or successor corporation), whether by virtue of any constitutional provision, statute or rule of law or by the enforcement of any assessment or penalty or otherwise; it being expressly agreed and understood that the Indenture and all the Bonds are solely corporate obligations and that any such personal liability is hereby expressly waived and released as a condition of, and as part of the consideration for, the execution of the Indenture and the issuance of this Bond.
