3.30% Collateral Mortgage Bonds due 2027, subject to no prior Lien (as defined in the Mortgage Indenture) to the knowledge of such counsel, except for Permitted Liens (as defined in the Mortgage Indenture), and (iii) deliver to the Trustee a

shall be fully registered in the name of the Trustee. Until the 3.30% Collateral Mortgage Bonds due 2027 are released in accordance with Section 211 of this Twenty-Ninth Supplemental Indenture, the Trustee shall hold the 3.30% Collateral
Mortgage Bonds due 2027 in trust for the benefit of the Holders from time to time of the 3.30% Senior Notes due 2027 as security for any and all obligations of the Company with respect to the 3.30% Senior Notes due 2027, including but not limited

Notes due 2027, either at the stated maturity thereof, upon acceleration of the maturity thereof or upon redemption, and (2) the full and prompt payment of any interest on the 3.30% Senior Notes due 2027, when and as the same shall become due
and payable in accordance with the terms and provisions of the Indenture or the 3.30% Senior Notes due 2027.

establish an account in the name of the Company for the custody and safekeeping of 3.30% Collateral Mortgage Bonds due 2027 delivered to the Trustee.” 

Section 1405    The Twenty-Ninth Supplemental Indenture (Amended 210). The
Twenty-Ninth Supplemental Indenture is hereby amended by the addition of Section 210 thereto, to read as follows: 

“Section 210    Actions with Respect to 3.30% Collateral Mortgage Bonds due 2027.

due 2027 unless the Trustee shall have received (i) written direction from the holders of at least a majority in aggregate principal amount of the Bonds then outstanding voting as a single class and (ii) indemnity or security satisfactory
to it against any liabilities that may be incurred by it in connection therewith; provided, however, that in no event shall the Trustee have any duty to attend meetings of bondholders under the Mortgage Indenture, or to ascertain or take

performance or observance of any covenants, conditions or agreements on the part of the Company or the Mortgage Bond Trustee with respect to the 3.30% Collateral Mortgage Bonds due 2027. The Trustee will not be required to take any action that is
contrary to applicable law or any provision of the Indenture, the 3.30% Collateral Mortgage Bonds due 2027 or the Mortgage Indenture or that, in the opinion of the Trustee, otherwise subjects it to liability; provided, however, that, subject
to the foregoing limitations and any other protections that the Trustee may have under the Indenture, 

  
 90 













 
including without limitation its right to indemnification for actions taken at the direction of the holders, the Trustee shall vote or give any such consent or instruction as it may be directed
to do so by the holders of a majority in principal amount of the 3.30% Senior Notes due 2027, unless the vote or consent is with respect to matters which under the Mortgage Indenture require the vote or consent of the holders of a greater percentage
in principal amount of the 3.30% Collateral Mortgage Bonds due 2027, in which case such direction must be from holders of such greater percentage in principal amount of the 3.30% Senior Notes due 2027. 

(b)    To the extent that any consent or instruction from the Trustee and/or the holders of the 3.30%
Senior Notes due 2027 is required with respect to the 3.30% Collateral Mortgage Bonds due 2027 and/or the Mortgage Indenture, the Trustee shall not have any duty or obligation to determine whether such consent or instruction is required nor any duty

recital, statement, representation, or warranty (whether written or oral) made by any Person in or in connection with the Indenture or the Mortgage Indenture or any certificate or other document referred to or provided for in, or received by it

3.30% Collateral Mortgage Bonds due 2027, the Mortgage Indenture, or any other document referred to or provided for therein or for any failure by the Company, the Mortgage Bond Trustee or any other Person to perform any of its obligations hereunder

immunities, indemnities and benefits given to the Trustee pursuant to the Indenture shall apply to any action taken by the Trustee in accordance with the terms of the 3.30% Collateral Mortgage Bonds due 2027 and/or the Mortgage Indenture. 

(e)    If an Event of Default under the Indenture occurs and is continuing with respect to the 3.30% Senior
Notes due 2027 and the 3.30% Senior Notes due 2027 have been accelerated as a consequence of such Event of Default, the Trustee may and, subject to Section 9.02 of the Indenture, upon receipt of written instructions of holders of not less than
a majority in principal amount of the 3.30% Senior Notes due 2027, and receipt of indemnity or security to its satisfaction, shall exercise such other rights as it shall possess under the Mortgage Indenture as a holder of the 3.30% Collateral
Mortgage Bonds due 2027. 

  
 91

majority in aggregate principal amount of the outstanding 3.30% Senior Notes due 2027, the Trustee may consent to modifications, amendments, or supplements to (or provide waivers in respect of) the 3.30% Collateral Mortgage Bonds due 2027 and/or the
Mortgage Indenture; provided, however, that without the written consent of each holder of a 3.30% Senior Note due 2027, the Trustee shall not consent to any modification, amendment or supplement to (or provide waivers in respect of) the 3.30%
Collateral Mortgage Bonds due 2027 and/or the Mortgage Indenture that have the effect of (A) (i) extending the fixed maturity of the 3.30% Collateral Mortgage Bonds due 2027, (ii) changing any terms of any sinking fund or analogous fund or
conversion rights with respect to the 3.30% Collateral Mortgage Bonds due 2027, (iii) reducing the rate or extending the time of payment of interest on the 3.30% Collateral Mortgage Bonds due 2027, or reducing the principal amount of the 3.30%
Collateral Mortgage Bonds due 2027, or (iv) limiting the right of the Trustee (as the holder of the 3.30% Collateral Mortgage Bonds due 2027) to institute suit for the enforcement of payment of principal of or premium, if any, or interest on
the 3.30% Collateral Mortgage Bonds due 2027 in accordance with the terms thereof, or (B) reducing the percentage of Bonds (as defined in the Mortgage Indenture), the holders of which are required to consent to any such supplement, amendment
and/or waiver, or (C) permitting the creation by the Company of any Senior Lien (as such term is defined in the Mortgage Indenture) in accordance with the Mortgage Indenture.”

the Indenture) in accordance with Section 8.02 of the Base Indenture have been satisfied, the Trustee shall be deemed not to hold a lien on the 3.30% Collateral Mortgage Bonds due 2027 on behalf of the holders of the 3.30% Senior Notes due 2027
and the Trustee shall, upon written request of the Company, deliver to the Company the 3.30% Collateral Mortgage Bonds due 2027, together with such appropriate instruments of transfer or release (in form and substance reasonably satisfactory to the
Trustee) as may be reasonably requested by the Company (and at the expense of the Company) to release such lien. All the 3.30% Collateral Mortgage Bonds due 2027 delivered to the Company in accordance with this Section 211 shall be delivered by

Twenty-Ninth Supplemental Indenture is hereby amended by the addition of Section 212 thereto, to read as follows: 

“Section 212    Delivery of Non-Payment Notice to
Mortgage Bond Trustee. If payment of the principal of, premium, if any, or interest on the 3.30% Senior Notes due 2027 has not been fully paid, deemed to have been paid or otherwise satisfied and discharged when due, the Trustee, acting at the
written direction of Holders of a majority in aggregate principal amount of the outstanding 3.30% Senior Notes due 2027, shall deliver a written notice to the Mortgage Bond Trustee stating the amount of such
non-payment and that such payment remains unpaid on the date of such notice (which notice shall be given by the Trustee within five Business Days of such direction; provided, however, that failure by
the Trustee to give such notice shall not affect in any way the Company’s obligation to pay such amount).”

incorporating the amendments effected by this Thirtieth Supplemental Indenture in accordance with Section 13.06 of the Base Indenture. In connection therewith, the Company has delivered to the Trustee (i) a Company Request for the

CUSIP No: 694308 GY7
	  	Principal Amount: $250,000,000

 PACIFIC GAS AND ELECTRIC COMPANY, a corporation duly organized and existing under the laws of the State of
California (herein called the “Company,” which term includes any successor Person pursuant to the applicable provisions of the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., as
nominee for The Depository Trust Company, or registered assigns, the Principal Amount stated above on the Maturity Date stated above, and to pay interest thereon from and including the Original Issue Date stated above or, in the case of a 4.50%
Senior Note due December 15, 2041 issued upon the registration of transfer or exchange, from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on the Interest
Payment Dates set forth above and on the Maturity Date stated above, commencing June 15, 2012 at the rate of 4.50% per annum until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or
duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this 4.50% Senior Note due December 15, 2041 (this “Senior Note,” and together with all other 4.50% Senior Notes
due December 15, 2041, the “Senior Notes”) (or one or more Predecessor Bonds) is registered at the close of business on the Regular Record Date for such interest, which shall be the 15th day preceding such Interest Payment
Date; provided, however, that interest payable at the Maturity Date or on a Redemption Date will be paid to the Person to whom principal is payable. 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 Senior Note (or one or more Predecessor Bonds) 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 Senior Notes 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 the Indenture and any securities exchange, if any, on which the Senior Notes may be listed, and upon such notice as may be required by any such exchange, all as more fully provided in said Indenture. 

Payments of interest on this Senior Note will include interest accrued to but excluding the respective Interest Payment Dates. Interest
payments for this Senior Note shall be computed and paid on the basis of the 360-day year of twelve 30-day months and will accrue from December 1, 2011 or from
the most recent Interest Payment Date to which interest has been paid or duly provided for. In the event that any date on which interest is payable on this Senior Note (other than the Maturity Date) is not a Business Day then payment of the interest
payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable. If the
Maturity Date falls on a day that is not a Business Day, the payment of principal, premium, if any, 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.













 Payment of principal of, premium, if any, and interest on Senior 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 of, premium, if any, and interest on the Senior Notes represented by a Global Bond shall be
made by wire transfer of immediately available funds to the Holder of such Global Bond, provided that, in the case of payments of principal and premium, if any, such Global Bond is first surrendered to the Paying Agent. If any of the Senior Notes
are no longer represented by a Global Bond, (i) payments of principal, premium, if any, and interest due on the Maturity Date or earlier redemption of such Senior Notes shall be made at the office of the Paying Agent upon surrender of such
Senior Notes to the Paying Agent, and (ii) payments of interest shall be made, at the option of the Company, subject to such surrender where applicable, (A) by check mailed to the address of the Person entitled thereto as such address
shall appear in the Bond Register or (B) by wire transfer to registered Holders of at least $10,000,000 in principal amount of Senior Notes at such place and to such account at a banking institution in the United States as such Holders may
designate in writing to the Trustee at least sixteen (16) days prior to the date for payment. 
 REFERENCE IS HEREBY MADE TO THE
FURTHER PROVISIONS OF THIS SENIOR NOTE SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE. 

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this
Senior Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

This Senior Note is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or more series under an Amended and
Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented by a Sixteenth Supplemental Indenture, dated as of December 1, 2011, and as amended by the Thirtieth
Supplemental Indenture, dated as of July 1, 2020 (as so amended and supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called
the “Indenture”), between the Company and BOKF, N.A., 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
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. This Senior Note is a
Bond within the meaning of the Indenture and is one of the Bonds of the thirty-fifth series designated as the 4.50% Senior Notes due December 15, 2041 established by the Company under the Indenture. The acceptance of this Senior Note shall be
deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 
 The Senior Notes
will be secured by a series of first mortgage bonds (the “4.50% Collateral Mortgage Bonds due 2041”) delivered by the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental
Indenture, dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”).
Reference is made to the Indenture and the Mortgage Indenture for a description of the rights of the Trustee as holder of the 4.50% Collateral Mortgage Bonds due 2041, the property mortgaged and pledged, the nature and extent of the security and
rights of the holders of the first mortgage bonds under the Mortgage Indenture and the rights of the Company under the Mortgage Indenture and the terms and conditions upon which the Senior Notes are secured. 

Subject to the terms and conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional
Redemption”), in whole or in part, (a) at any time prior to June 15, 2041 at a Redemption Price equal to the greater of: 

(i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and
interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 25 basis points, 

plus, in either of the above cases, accrued and unpaid interest thereon to but not including the Redemption Date; and (b) at any time on or after
June 15, 2041, at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 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 Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $1,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall
be conclusive and binding upon such Holder and upon all future Holders of this Senior Note and of any Senior Note 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 Senior Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Senior Notes 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, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note of this series during a period of 15 days immediately preceding the date notice is to be given identifying the
serial numbers of the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part. 

Prior to due presentment of this Senior Note for registration of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary. 
 This Senior Note 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
Senior Note, 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 Senior Note. 

All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.

CUSIP No: 694308 GZ4 
 PACIFIC GAS AND ELECTRIC
COMPANY, a corporation duly organized and existing under the laws of the State of California (herein called the “Company,” which term includes any successor Person pursuant to the applicable provisions of the Indenture hereinafter referred
to), for value received, hereby promises to pay to Cede & Co., as nominee for The Depository Trust Company, or registered assigns, the Principal Amount stated above on the Maturity Date stated above, and to pay interest thereon from and
including the Original Issue Date stated above or, in the case of a 4.45% Senior Note due April 15, 2042 issued upon the registration of transfer or exchange, from and including the most recent Interest Payment Date to which interest has been
paid or duly provided for, semi-annually in arrears on the Interest Payment Dates set forth above and on the Maturity Date stated above, commencing October 15, 2012 at the rate of 4.45% per annum until the principal hereof is paid or made
available for payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this 4.45% Senior Note due April 15, 2042 (this
“Senior Note,” and together with all other 4.45% Senior Notes due April 15, 2042, the “Senior Notes”) (or one or more Predecessor Bonds) is registered at the close of business on the Regular Record Date for such interest,
which shall be the 15th day preceding such Interest Payment Date; provided, however, that interest payable at the Maturity Date or on a Redemption Date will be paid to the Person to whom principal is payable. 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 Senior Note (or one or more Predecessor Bonds) 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 Senior Notes 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 the Indenture and any securities exchange, if any, on which the Senior Notes may be listed, and upon such notice as may be required by any such exchange, all as more fully
provided in said Indenture. 
 Payments of interest on this Senior Note will include interest accrued to but excluding the respective
Interest Payment Dates. Interest payments for this Senior Note shall be computed and paid on the basis of the 360-day year of twelve 30-day months and will accrue from
April 16, 2012 or from the most recent Interest Payment Date to which interest has been paid or duly provided for. In the event that any date on which interest is payable on this Senior Note (other than the Maturity Date) is not a Business Day
then payment of the interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or payment in respect of any such delay) with the same force and effect as if made on the date the payment was
originally payable. If the Maturity Date falls on a day that is not a Business Day, the payment of principal, premium, if any, 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. 












 Payment of principal of, premium, if any, and interest on Senior Notes shall be made in such

are no longer represented by a Global Bond, (i) payments of principal, premium, if any, and interest due on the Maturity Date or earlier redemption of such Senior Notes shall be made at the office of the Paying Agent upon surrender of such
Senior Notes to the Paying Agent, and (ii) payments of interest shall be made, at the option of the Company, subject to such surrender where applicable, (A) by check mailed to the address of the Person entitled thereto as such address
shall appear in the Bond Register or (B) by wire transfer to registered Holders of at least $10,000,000 in principal amount of Senior Notes at such place and to such account at a banking institution in the United States as such Holders may
designate in writing to the Trustee at least sixteen (16) days prior to the date for payment.

 Reverse of Amended and Restated 4.45% Senior Note due April 15, 2042 

This Senior Note is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or more series under an Amended and
Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented by a Seventeenth Supplemental Indenture, dated as of April 16, 2012, and as amended by the Thirtieth
Supplemental Indenture, dated as of July 1, 2020 (as so amended and supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called
the “Indenture”), between the Company and BOKF, N.A., 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
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. This Senior Note is a
Bond within the meaning of the Indenture and is one of the Bonds of the thirty-sixth series designated as the 4.45% Senior Notes due April 15, 2042 established by the Company under the Indenture. The acceptance of this Senior Note shall be
deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 
 The Senior Notes
will be secured by a series of first mortgage bonds (the “4.45% Collateral Mortgage Bonds due 2042”) delivered by the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental
Indenture, dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”).
Reference is made to the Indenture and the Mortgage Indenture for a description of the rights of the Trustee as holder of the 4.45% Collateral Mortgage Bonds due 2042, the property mortgaged and pledged, the nature and extent of the security and
rights of the holders of the first mortgage bonds under the Mortgage Indenture and the rights of the Company under the Mortgage Indenture and the terms and conditions upon which the Senior Notes are secured. 

Subject to the terms and conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional
Redemption”), in whole or in part, (a) at any time prior to October 15, 2041 at a Redemption Price equal to the greater of: 

(i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and
interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 20 basis points, 

plus, in either of the above cases, accrued and unpaid interest thereon to but not including the Redemption Date; and (b) at any time on or after
October 15, 2041 at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 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 Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $1,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall be conclusive and binding upon such
Holder and upon all future Holders of this Senior Note and of any Senior Note 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 Senior Note.

 As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is
registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Senior Notes 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, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of
the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part. 

Prior to due presentment of this Senior Note for registration of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary. 
 This Senior Note 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
Senior Note, 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 Senior Note. 

All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.

due August 15, 2042, the “Senior Notes”) (or one or more Predecessor Bonds) is registered at the close of business on the Regular Record Date for such interest, which shall be the 15th day preceding such Interest Payment
Date; provided, however, that interest payable at the Maturity Date or on a Redemption Date will be paid to the Person to whom principal is payable. 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 Senior Note (or one or more Predecessor Bonds) 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 Senior Notes 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

payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable. If the
Maturity Date falls on a day that is not a Business Day, the payment of principal, premium, if any, 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.













 Payment of principal of, premium, if any, and interest on Senior 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 of, premium, if any, and interest on the Senior Notes represented by a Global Bond shall be

are no longer represented by a Global Bond, (i) payments of principal, premium, if any, and interest due on the Maturity Date or earlier redemption of such Senior Notes shall be made at the office of the Paying Agent upon surrender of such
Senior Notes to the Paying Agent, and (ii) payments of interest shall be made, at the option of the Company, subject to such surrender where applicable, (A) by check mailed to the address of the Person entitled thereto as such address
shall appear in the Bond Register or (B) by wire transfer to registered Holders of at least $10,000,000 in principal amount of Senior Notes at such place and to such account at a banking institution in the United States as such Holders may

 Reverse of Amended and Restated 3.75% Senior Note due August 15, 2042 

This Senior Note is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or more series under an Amended and
Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented by a Eighteenth Supplemental Indenture, dated as of August 16, 2012, and as amended by the Thirtieth
Supplemental Indenture, dated as of July 1, 2020 (as so amended and supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called
the “Indenture”), between the Company and BOKF, N.A., 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
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. This Senior Note is a
Bond within the meaning of the Indenture and is one of the Bonds of the thirty-eighth series designated as the 3.75% Senior Notes due August 15, 2042 established by the Company under the Indenture. The acceptance of this Senior Note shall be
deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 
 The Senior Notes
will be secured by a series of first mortgage bonds (the “3.75% Collateral Mortgage Bonds due 2042”) delivered by the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental
Indenture, dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”).
Reference is made to the Indenture and the Mortgage Indenture for a description of the rights of the Trustee as holder of the 3.75% Collateral Mortgage Bonds due 2042, the property mortgaged and pledged, the nature and extent of the security and
rights of the holders of the first mortgage bonds under the Mortgage Indenture and the rights of the Company under the Mortgage Indenture and the terms and conditions upon which the Senior Notes are secured. 

Subject to the terms and conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional
Redemption”), in whole or in part, (a) at any time prior to February 15, 2042 at a Redemption Price equal to the greater of: 

(i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and
interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 20 basis points, 

plus, in either of the above cases, accrued and unpaid interest thereon to but not including the Redemption Date; and (b) at any time on or after
February 15, 2042 at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 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 Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $1,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall be conclusive and binding upon such Holder and upon all future Holders of this Senior Note and of any Senior Note 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 Senior Note. 

As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is
registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Senior Notes 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, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note of this series during a period of 15 days immediately preceding the date notice is to be given identifying the
serial numbers of the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part. 

Prior to due presentment of this Senior Note for registration of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary. 
 This Senior Note 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
Senior Note, 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 Senior Note. 

All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.

payable to Holders of such Senior Notes, 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 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 Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $1,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall be conclusive and binding upon such
Holder and upon all future Holders of this Senior Note and of any Senior Note 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 Senior Note.

 As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is
registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Senior Notes 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, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of
the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part. 

Prior to due presentment of this Senior Note for registration of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary. 
 This Senior Note 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
Senior Note, 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 Senior Note. 

All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.

 PACIFIC GAS AND ELECTRIC COMPANY, a corporation duly organized and existing under the laws of the State of
California (herein called the “Company,” which term includes any successor Person pursuant to the applicable provisions of the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., as
nominee for The Depository Trust Company, or registered assigns, the Principal Amount stated above on the Maturity Date stated above, and to pay interest thereon from and including the Original Issue Date stated above or, in the case of a 4.60%
Senior Note due June 15, 2043 issued upon the registration of transfer or exchange, from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on the Interest Payment
Dates set forth above and on the Maturity Date stated above, commencing December 15, 2013 at the rate of 4.60% per annum until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this 4.60% Senior Note due June 15, 2043 (this “Senior Note,” and together with all other 4.60% Senior Notes due
June 15, 2043, the “Senior Notes”) (or one or more Predecessor Bonds) is registered at the close of business on the Regular Record Date for such interest, which shall be the 15th day preceding such Interest Payment
Date; provided, however, that interest payable at the Maturity Date or on a Redemption Date will be paid to the Person to whom principal is payable. 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 Senior Note (or one or more Predecessor Bonds) 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 Senior Notes 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 the Indenture and any securities exchange, if any, on which the Senior Notes may be listed, and upon such notice as may be required by any such exchange, all as more fully provided in said Indenture. 

Payments of interest on this Senior Note will include interest accrued to but excluding the respective Interest Payment Dates. Interest
payments for this Senior Note shall be computed and paid on the basis of the 360-day year of twelve 30-day months and will accrue from June 14, 2013 or from the
most recent Interest Payment Date to which interest has been paid or duly provided for. In the event that any date on which interest is payable on this Senior Note (other than the Maturity Date) is not a Business Day then payment of the interest
payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable. If the
Maturity Date falls on a day that is not a Business Day, the payment of principal, premium, if any, 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.













 Payment of principal of, premium, if any, and interest on Senior 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 of, premium, if any, and interest on the Senior Notes represented by a Global Bond shall be

are no longer represented by a Global Bond, (i) payments of principal, premium, if any, and interest due on the Maturity Date or earlier redemption of such Senior Notes shall be made at the office of the Paying Agent upon surrender of such
Senior Notes to the Paying Agent, and (ii) payments of interest shall be made, at the option of the Company, subject to such surrender where applicable, (A) by check mailed to the address of the Person entitled thereto as such address
shall appear in the Bond Register or (B) by wire transfer to registered Holders of at least $10,000,000 in principal amount of Senior Notes at such place and to such account at a banking institution in the United States as such Holders may

 Reverse of Amended and Restated 4.60% Senior Note due June 15, 2043 

This Senior Note is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or more series under an Amended and
Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented by a Nineteenth Supplemental Indenture, dated as of June 14, 2013, and as amended by the Thirtieth
Supplemental Indenture, dated as of July 1, 2020 (as so amended and supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called
the “Indenture”), between the Company and BOKF, N.A., 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
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. This Senior Note is a
Bond within the meaning of the Indenture and is one of the Bonds of the fortieth series designated as the 4.60% Senior Notes due June 15, 2043 established by the Company under the Indenture. The acceptance of this Senior Note shall be deemed to
constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 
 The Senior Notes will be
secured by a series of first mortgage bonds (the “4.60% Collateral Mortgage Bonds due 2043”) delivered by the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental Indenture,
dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”). Reference is
made to the Indenture and the Mortgage Indenture for a description of the rights of the Trustee as holder of the 4.60% Collateral Mortgage Bonds due 2043, the property mortgaged and pledged, the nature and extent of the security and rights of the
holders of the first mortgage bonds under the Mortgage Indenture and the rights of the Company under the Mortgage Indenture and the terms and conditions upon which the Senior Notes are secured. 

Subject to the terms and conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional
Redemption”), in whole or in part, (a) at any time prior to December 15, 2042 at a Redemption Price equal to the greater of: 

(i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and
interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 20 basis points, 

plus, in either of the above cases, accrued and unpaid interest thereon to but not including the Redemption Date; and (b) at any time on or after
December 15, 2042 at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 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 Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $1,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall be conclusive and binding upon such
Holder and upon all future Holders of this Senior Note and of any Senior Note 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 Senior Note.

 As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is
registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Senior Notes 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, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of
the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part. 

Prior to due presentment of this Senior Note for registration of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary. 
 This Senior Note 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
Senior Note, 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 Senior Note. 

All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.

 Reverse of Amended and Restated 3.85% Senior Note due November 15, 2023 

This Senior Note is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or more series under an Amended and
Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented by a Twentieth Supplemental Indenture, dated as of November 12, 2013, and as amended by the Thirtieth
Supplemental Indenture, dated as of July 1, 2020 (as so amended and supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called
the “Indenture”), between the Company and BOKF, N.A., 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
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. This Senior Note is a
Bond within the meaning of the Indenture and is one of the Bonds of the forty-first series designated as the 3.85% Senior Notes due November 15, 2023 established by the Company under the Indenture. The acceptance of this Senior Note shall be
deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 
 The Senior Notes
will be secured by a series of first mortgage bonds (the “3.85% Collateral Mortgage Bonds due 2023”) delivered by the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental
Indenture, dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”).
Reference is made to the Indenture and the Mortgage Indenture for a description of the rights of the Trustee as holder of the 3.85% Collateral Mortgage Bonds due 2023, the property mortgaged and pledged, the nature and extent of the security and
rights of the holders of the first mortgage bonds under the Mortgage Indenture and the rights of the Company under the Mortgage Indenture and the terms and conditions upon which the Senior Notes are secured. 

Subject to the terms and conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional
Redemption”), in whole or in part, (a) at any time prior to August 15, 2023 at a Redemption Price equal to the greater of: 

(i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and
interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 20 basis points, 

plus, in either of the above cases, accrued and unpaid interest thereon to but not including the Redemption Date; and (b) at any time on or after
August 15, 2023 at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 10 days
nor more than 60 days prior to the Redemption Date to each Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $1,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall be conclusive and binding upon such
Holder and upon all future Holders of this Senior Note and of any Senior Note 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 Senior Note.

 As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is
registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Senior Notes 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, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of
the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part. 

Prior to due presentment of this Senior Note for registration of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary. 
 This Senior Note 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
Senior Note, 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 Senior Note. 

All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.

The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”). Reference is made to the Indenture and the Mortgage Indenture for a description of the rights of the Trustee as holder of the 3.75%
Collateral Mortgage Bonds due 2024, the property mortgaged and pledged, the nature and extent of the security and rights of the holders of the first mortgage bonds under the Mortgage Indenture and the rights of the Company under the Mortgage
Indenture and the terms and conditions upon which the Senior Notes are secured. 
 Subject to the terms and conditions of the Indenture, the
Senior Notes are redeemable at the option of the Company (“Optional Redemption”), in whole or in part, (a) at any time prior to November 15, 2023 at a Redemption Price equal to the greater of: 

(i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and
interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 20 basis points, 

plus, in either of the above cases, accrued and unpaid interest thereon to but not including the Redemption Date; and (b) at any time on or after
November 15, 2023 at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 10 days
nor more than 60 days prior to the Redemption Date to each Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $1,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall be conclusive and binding upon such
Holder and upon all future Holders of this Senior Note and of any Senior Note 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 Senior Note.

 As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is
registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Senior Notes 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, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of
the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part. 

Prior to due presentment of this Senior Note for registration of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary. 
 This Senior Note 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
Senior Note, 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 Senior Note. 

All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.

CUSIP No: 694308 HH3
	  	Principal Amount: $450,000,000

 PACIFIC GAS AND ELECTRIC COMPANY, a corporation duly organized and existing under the laws of the State of
California (herein called the “Company,” which term includes any successor Person pursuant to the applicable provisions of the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., as
nominee for The Depository Trust Company, or registered assigns, the Principal Amount stated above on the Maturity Date stated above, and to pay interest thereon from and including the Original Issue Date stated above or, in the case of a 4.75%
Senior Note due February 15, 2044 issued upon the registration of transfer or exchange, from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on the Interest
Payment Dates set forth above and on the Maturity Date stated above, commencing August 15, 2014 at the rate of 4.75% per annum until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid
or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this 4.75% Senior Note due February 15, 2044 (this “Senior Note,” and together with all other 4.75% Senior
Notes due February 15, 2044, the “Senior Notes”) (or one or more Predecessor Bonds) is registered at the close of business on the Regular Record Date for such interest, which shall be the 15th day preceding such Interest Payment
Date; provided, however, that interest payable at the Maturity Date or on a Redemption Date will be paid to the Person to whom principal is payable. 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 Senior Note (or one or more Predecessor Bonds) 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 Senior Notes 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 the Indenture and any securities exchange, if any, on which the Senior Notes may be listed, and upon such notice as may be required by any such exchange, all as more fully provided in said Indenture. 

Payments of interest on this Senior Note will include interest accrued to but excluding the respective Interest Payment Dates. Interest
payments for this Senior Note shall be computed and paid on the basis of the 360-day year of twelve 30-day months and will accrue from February 21, 2014 or from the
most recent Interest Payment Date to which interest has been paid or duly provided for. In the event that any date on which interest is payable on this Senior Note (other than the Maturity Date) is not a Business Day then payment of the interest
payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable. If the
Maturity Date falls on a day that is not a Business Day, the payment of principal, premium, if any, 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.













 Payment of principal of, premium, if any, and interest on Senior Notes shall be made in such

are no longer represented by a Global Bond, (i) payments of principal, premium, if any, and interest due on the Maturity Date or earlier redemption of such Senior Notes shall be made at the office of the Paying Agent upon surrender of such
Senior Notes to the Paying Agent, and (ii) payments of interest shall be made, at the option of the Company, subject to such surrender where applicable, (A) by check mailed to the address of the Person entitled thereto as such address
shall appear in the Bond Register or (B) by wire transfer to registered Holders of at least $10,000,000 in principal amount of Senior Notes at such place and to such account at a banking institution in the United States as such Holders may
designate in writing to the Trustee at least sixteen (16) days prior to the date for payment. 
 REFERENCE IS HEREBY MADE TO THE
FURTHER PROVISIONS OF THIS SENIOR NOTE SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

This Senior Note is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or more series under an Amended and
Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented a Twenty-First Supplemental Indenture, dated as of February 21, 2014, and as amended by the Thirtieth
Supplemental Indenture, dated as of July 1, 2020 (as so amended and supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called
the “Indenture”), between the Company and BOKF, N.A., 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
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. This Senior Note is a
Bond within the meaning of the Indenture and is one of the Bonds of the forty-fourth series designated as the 4.75% Senior Notes due February 15, 2044 established by the Company under the Indenture. The acceptance of this Senior Note shall be
deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 
 The Senior Notes
will be secured by a series of first mortgage bonds (the “4.75% Collateral Mortgage Bonds due 2044”) delivered by the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental
Indenture, dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”).
Reference is made to the Indenture and the Mortgage Indenture for a description of the rights of the Trustee as holder of the 4.75% Collateral Mortgage Bonds due 2044, the property mortgaged and pledged, the nature and extent of the security and
rights of the holders of the first mortgage bonds under the Mortgage Indenture and the rights of the Company under the Mortgage Indenture and the terms and conditions upon which the Senior Notes are secured. 

Subject to the terms and conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional
Redemption”), in whole or in part, (a) at any time prior to August 15, 2043 at a Redemption Price equal to the greater of: 

(i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and interest on the
Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 20 basis points, 

plus, in either of the above cases, accrued and unpaid interest thereon to but not including the Redemption Date; and (b) at any time on or after
August 15, 2043 at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 10 days
nor more than 60 days prior to the Redemption Date to each Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $1,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall be conclusive and binding upon such
Holder and upon all future Holders of this Senior Note and of any Senior Note 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 Senior Note.

 As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is
registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Senior Notes 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, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of
the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part. 

Prior to due presentment of this Senior Note for registration of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary. 
 This Senior Note 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
Senior Note, 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,

 PACIFIC GAS AND ELECTRIC COMPANY, a corporation duly organized and existing under the laws of the State of
California (herein called the “Company,” which term includes any successor Person pursuant to the applicable provisions of the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., as
nominee for The Depository Trust Company, or registered assigns, the Principal Amount stated above on the Maturity Date stated above, and to pay interest thereon from and including the Original Issue Date stated above or, in the case of a 4.75%
Senior Note due February 15, 2044 issued upon the registration of transfer or exchange, from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on the Interest
Payment Dates set forth above and on the Maturity Date stated above, commencing February 15, 2015 at the rate of 4.75% per annum until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or
duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this 4.75% Senior Note due February 15, 2044 (this “Senior Note,” and together with all other 4.75% Senior Notes
due February 15, 2044, the “Senior Notes”) (or one or more Predecessor Bonds) is registered at the close of business on the Regular Record Date for such interest, which shall be the 15th day preceding such Interest Payment Date;
provided, however, that interest payable at the Maturity Date or on a Redemption Date will be paid to the Person to whom principal is payable. 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 Senior Note (or one or more Predecessor Bonds) 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 Senior Notes 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 the Indenture and any securities exchange, if any, on which the Senior Notes may be listed, and upon such notice as may be required by any such exchange, all as more fully provided in said Indenture. 

Payments of interest on this Senior Note will include interest accrued to but excluding the respective Interest Payment Dates. Interest
payments for this Senior Note shall be computed and paid on the basis of the 360-day year of twelve 30-day months and will accrue from August 15, 2014 or from the
most recent Interest Payment Date to which interest has been paid or duly provided for. In the event that any date on which interest is payable on this Senior Note (other than the Maturity Date) is not a Business Day then payment of the interest
payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable. If the
Maturity Date falls on a day that is not a Business Day, the payment of principal, premium, if any, 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.













 Payment of principal of, premium, if any, and interest on Senior Notes shall be made in such

Senior Notes to the Paying Agent, and (ii) payments of interest shall be made, at the option of the Company, subject to such surrender where applicable, (A) by check mailed to the address of the Person entitled thereto as such address
shall appear in the Bond Register or (B) by wire transfer to registered Holders of at least $10,000,000 in principal amount of Senior Notes at such place and to such account at a banking institution in the United States as such Holders may
designate in writing to the Trustee at least sixteen (16) days prior to the date for payment.

 Reverse of Amended and Restated 4.75% Senior Note due February 15, 2044 

This Senior Note is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or more series under an Amended and
Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented by a Twenty-First Supplemental Indenture dated as of February 21, 2014, and as amended by the Thirtieth
Supplemental Indenture, dated as of July 1, 2020 (as so amended and supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called
the “Indenture”), between the Company and BOKF, N.A., 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
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. This Senior Note is a
Bond within the meaning of the Indenture and is one of the Bonds of the forty-fourth series designated as the 4.75% Senior Notes due February 15, 2044 established by the Company under the Indenture and initially issued in an aggregate principal
amount of $450,000,000 on February 21, 2014. As a result of the further issuance of $225,000,000 aggregate principal amount of Bonds of the forty-fourth series on August 18, 2014, the issued amount of Bonds of such series now totals
$675,000,000. The acceptance of this Senior Note shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 

The Senior Notes will be secured by a series of first mortgage bonds (the “4.75% Collateral Mortgage Bonds due 2044”) delivered by
the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental Indenture, dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and
The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”). Reference is made to the Indenture and the Mortgage Indenture for a description of the rights of the Trustee as holder of the 4.75%
Collateral Mortgage Bonds due 2044, the property mortgaged and pledged, the nature and extent of the security and rights of the holders of the first mortgage bonds under the Mortgage Indenture and the rights of the Company under the Mortgage
Indenture and the terms and conditions upon which the Senior Notes are secured. 
 Subject to the terms and conditions of the Indenture, the
Senior Notes are redeemable at the option of the Company (“Optional Redemption”), in whole or in part, (a) at any time prior to August 15, 2043 at a Redemption Price equal to the greater of: 

(i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and
interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 20 basis points, 

plus, in either of the above cases, accrued and unpaid interest thereon to but not including the Redemption Date; and (b) at any time on or after
August 15, 2043 at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 10 days
nor more than 60 days prior to the Redemption Date to each Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $1,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall be conclusive and binding upon such Holder and upon all future Holders of this Senior Note and of any Senior Note 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 Senior Note. 
 As provided in and subject to the provisions of
the Indenture, the Holder of this Senior Note 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
Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is registrable in the Bond
Register, upon surrender of this Senior Note 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 Senior Note 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
Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 












 The Senior Notes 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, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note
of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except
the unredeemed portion of any Senior Note being redeemed in part. 
 Prior to due presentment of this Senior Note for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 This Senior Note 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
Senior Note, 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 Senior Note. 

All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.

 Reverse of Amended and Restated 3.40% Senior Note due August 15, 2024 

This Senior Note is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or more series under an Amended and
Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented by a Twenty-Third Supplemental Indenture, dated as of August 18, 2014, and as amended by the Thirtieth
Supplemental Indenture, dated as of July 1, 2020 (as so amended and supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called
the “Indenture”), between the Company and BOKF, N.A., 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
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. This Senior Note is a
Bond within the meaning of the Indenture and is one of the Bonds of the forty-sixth series designated as the 3.40% Senior Notes due August 15, 2024 established by the Company under the Indenture. The acceptance of this Senior Note shall be
deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 
 The Senior Notes
will be secured by a series of first mortgage bonds (the “3.40% Collateral Mortgage Bonds due 2024”) delivered by the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental
Indenture, dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”).
Reference is made to the Indenture and the Mortgage Indenture for a description of the rights of the Trustee as holder of the 3.40% Collateral Mortgage Bonds due 2024, the property mortgaged and pledged, the nature and extent of the security and
rights of the holders of the first mortgage bonds under the Mortgage Indenture and the rights of the Company under the Mortgage Indenture and the terms and conditions upon which the Senior Notes are secured. 

Subject to the terms and conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional
Redemption”), in whole or in part, (a) at any time prior to May 15, 2024 (the date that is three months prior to the Maturity Date) at a Redemption Price equal to the greater of: 

(i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and
interest on the 3.40% Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date), calculated as if the Maturity Date of such 3.40% Senior Notes was May 15, 2024 (the date that is three
months prior to the Maturity Date), discounted to the Redemption Date on a semiannual basis at the Adjusted Treasury Rate, plus 15 basis points; 
 plus, in
either of the above cases, accrued and unpaid interest thereon to but not including the Redemption Date; and (b) at any time on or after May 15, 2024 (the date that is three months prior to the Maturity Date) at 100% of the principal
amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 10 days
nor more than 60 days prior to the Redemption Date to each Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $2,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall
be conclusive and binding upon such Holder and upon all future Holders of this Senior Note and of any Senior Note 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 Senior Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 












 The Senior Notes are issuable only in registered form without coupons in denominations of
$2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note
of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except
the unredeemed portion of any Senior Note being redeemed in part. 
 Prior to due presentment of this Senior Note for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 This Senior Note 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
Senior Note, 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 Senior Note. 

All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.

Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented by a Twenty-Fourth Supplemental Indenture, dated as of November 6, 2014 and as amended by the Thirtieth
Supplemental Indenture, dated as of July 1, 2020 (as so amended and supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called
the “Indenture”), between the Company and BOKF, N.A., 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
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. This Senior Note is a
Bond within the meaning of the Indenture and is one of the Bonds of the forty-seventh series designated as the 4.30% Senior Notes due March 15, 2045 established by the Company under the Indenture. The acceptance of this Senior Note shall be
deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 
 The Senior Notes
will be secured by a series of first mortgage bonds (the “4.30% Collateral Mortgage Bonds due 2045”) delivered by the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental
Indenture, dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”).

Subject to the terms and conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional
Redemption”), in whole or in part, (a) at any time prior to September 15, 2044 (the date that is six months prior to the Maturity Date) at a Redemption Price equal to the greater of: 

(i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and

to the Maturity Date), discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 20 basis points, 
 plus, in either of
the above cases, accrued and unpaid interest thereon to but not including the Redemption Date; and (b) at any time on or after September 15, 2044 (the date that is six months prior to the Maturity Date) at 100% of the principal amount of
the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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

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 Senior Notes or portions thereof shall cease to bear interest.

 In
the event of redemption of this Senior Note in part only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall be 












 
conclusive and binding upon such Holder and upon all future Holders of this Senior Note and of any Senior Note 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 Senior Note. 
 As provided in and subject to the provisions of
the Indenture, the Holder of this Senior Note 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
Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is registrable in the Bond
Register, upon surrender of this Senior Note 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 Senior Note 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
Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Senior Notes 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, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of
the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part. 

Prior to due presentment of this Senior Note for registration of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary. 












 This Senior Note 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
Senior Note, 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 Senior Note. 

All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.

 PACIFIC GAS AND ELECTRIC COMPANY, a corporation duly organized and existing under the laws of the State of
California (herein called the “Company,” which term includes any successor Person pursuant to the applicable provisions of the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., as
nominee for The Depository Trust Company, or registered assigns, the Principal Amount stated above on the Maturity Date stated above, and to pay interest thereon from and including the Original Issue Date stated above or, in the case of a 4.30%
Senior Note due March 15, 2045 issued upon the registration of transfer or exchange, from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears on the Interest Payment
Dates set forth above and on the Maturity Date stated above, commencing September 15, 2015 at the rate of 4.30% per annum until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this 4.30% Senior Note due March 15, 2045 (this “Senior Note,” and together with all other 4.30% Senior Notes due
March 15, 2045, the “Senior Notes”) (or one or more Predecessor Bonds) is registered at the close of business on the Regular Record Date for such interest, which shall be the 15th day preceding such Interest Payment Date;
provided, however, that interest payable at the Maturity Date or on a Redemption Date will be paid to the Person to whom principal is payable. 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 Senior Note (or one or more Predecessor Bonds) 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 Senior Notes 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 the Indenture and any securities exchange, if any, on which the Senior Notes may be listed, and upon such notice as may be required by any such exchange, all as more fully provided in said Indenture. 

Payments of interest on this Senior Note will include interest accrued to but excluding the respective Interest Payment Dates. Interest
payments for this Senior Note shall be computed and paid on the basis of the 360-day year of twelve 30-day months and will accrue from March 15, 2015 or from the
most recent Interest Payment Date to which interest has been paid or duly provided for. In the event that any date on which interest is payable on this Senior Note (other than the Maturity Date) is not a Business Day then payment of the interest
payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable. If the
Maturity Date falls on a day that is not a Business Day, the payment of principal, premium, if any, 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.













 Payment of principal of, premium, if any, and interest on Senior 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 of, premium, if any, and interest on the Senior Notes represented by a Global Bond shall be

are no longer represented by a Global Bond, (i) payments of principal, premium, if any, and interest due on the Maturity Date or earlier redemption of such Senior Notes shall be made at the office of the Paying Agent upon surrender of such
Senior Notes to the Paying Agent, and (ii) payments of interest shall be made, at the option of the Company, subject to such surrender where applicable, (A) by check mailed to the address of the Person entitled thereto as such address
shall appear in the Bond Register or (B) by wire transfer to registered Holders of at least $10,000,000 in principal amount of Senior Notes at such place and to such account at a banking institution in the United States as such Holders may
designate in writing to the Trustee at least sixteen (16) days prior to the date for payment. 
 REFERENCE IS HEREBY MADE TO THE
FURTHER PROVISIONS OF THIS SENIOR NOTE SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE. 

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this
Senior Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

 Reverse of Amended and Restated 4.30% Senior Note due March 15, 2045 

This Senior Note is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or more series under an Amended and
Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented by a Twenty-Fourth Supplemental Indenture, dated as of November 6, 2014, and a Twenty-Fifth
Supplemental Indenture, dated June 12, 2015 and as amended by the Thirtieth Supplemental Indenture, dated as of July 1, 2020 (as so supplemented, and together with all additional indentures supplemental thereto, and any constituent
instruments establishing the terms of particular Bonds, being herein called the “Indenture”), between the Company and BOKF, N.A., 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 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. This Senior Note is a Bond within the meaning of the Indenture and is one of the Bonds of the forty-seventh series designated as the 4.30% Senior Notes due March 15, 2045 established
by the Company under the Indenture and initially issued in an aggregate principal amount of $500,000,000 on November 6, 2014. As a result of the further issuance of $100,000,000 aggregate principal amount of Bonds of the forty-seventh series on
June 12, 2015, the issued amount of Bonds of such series now totals $600,000,000. The acceptance of this Senior Note shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the
Indenture. 
 The Senior Notes will be secured by a series of first mortgage bonds (the “4.30% Collateral Mortgage Bonds due
2045”) delivered by the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental Indenture, dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020,
between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”). Reference is made to the Indenture and the Mortgage Indenture for a description of the rights of the
Trustee as holder of the 4.30% Collateral Mortgage Bonds due 2045, the property mortgaged and pledged, the nature and extent of the security and rights of the holders of the first mortgage bonds under the Mortgage Indenture and the rights of the
Company under the Mortgage Indenture and the terms and conditions upon which the Senior Notes are secured. 
 Subject to the terms and
conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional Redemption”), in whole or in part, (a) at any time prior to September 15, 2044 (the date that is six months prior to the
Maturity Date) at a Redemption Price equal to the greater of: 
 (i)    100% of the principal amount of the Senior Notes
to be redeemed; or 
 (ii)    as determined by the Quotation Agent, the sum of the present values of the Remaining
Scheduled Payments of principal and interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date), calculated as if the Maturity Date of such Senior Notes was September 15,
2044 (the date that is six months prior to the Maturity Date), discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 20 basis points, 












 plus, in either of the above cases, accrued and unpaid interest thereon to but not including the Redemption
Date; and (b) at any time on or after September 15, 2044 (the date that is six months prior to the Maturity Date) at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 10 days
nor more than 60 days prior to the Redemption Date to each Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $1,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall be conclusive and binding
upon such Holder and upon all future Holders of this Senior Note and of any Senior Note 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
Senior Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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
Senior 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 any premium and interest on this Senior Note 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
Senior Note is registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of
authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The
Senior Notes 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, Senior Notes are exchangeable for a
like aggregate principal amount of Senior Notes 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 Senior Note of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of the Senior Notes called for
redemption, or (B) any Senior Note selected for redemption in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part.

 PACIFIC GAS AND ELECTRIC COMPANY, a corporation duly organized and existing under the laws of the State of
California (herein called the “Company,” which term includes any successor Person pursuant to the applicable provisions of the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., as
nominee for The Depository Trust Company, or registered assigns, the Principal Amount stated above on the Maturity Date stated above, and to pay interest thereon from and including the Original Issue Date stated above or, in the case of a 3.50%
Senior Note due June 15, 2025 issued upon the registration of transfer or exchange, from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears on the Interest Payment
Dates set forth above and on the Maturity Date stated above, commencing December 15, 2015 at the rate of 3.50% per annum until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this 3.50% Senior Note due June 15, 2025 (this “Senior Note,” and together with all other 3.50% Senior Notes due
June 15, 2025, the “Senior Notes”) (or one or more Predecessor Bonds) is registered at the close of business on the Regular Record Date for such interest, which shall be the 15th day preceding such Interest Payment Date;
provided, however, that interest payable at the Maturity Date or on a Redemption Date will be paid to the Person to whom principal is payable. 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 Senior Note (or one or more Predecessor Bonds) 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 Senior Notes 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 the Indenture and any securities exchange, if any, on which the Senior Notes may be listed, and upon such notice as may be required by any such exchange, all as more fully provided in said Indenture. 

Payments of interest on this Senior Note will include interest accrued to but excluding the respective Interest Payment Dates. Interest
payments for this Senior Note shall be computed and paid on the basis of the 360-day year of twelve 30-day months and will accrue from June 12, 2015 or from the
most recent Interest Payment Date to which interest has been paid or duly provided for. In the event that any date on which interest is payable on this Senior Note (other than the Maturity Date) is not a Business Day then payment of the interest
payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable. If the
Maturity Date falls on a day that is not a Business Day, the payment of principal, premium, if any, 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.













 Payment of principal of, premium, if any, and interest on Senior Notes shall be made in such

are no longer represented by a Global Bond, (i) payments of principal, premium, if any, and interest due on the Maturity Date or earlier redemption of such Senior Notes shall be made at the office of the Paying Agent upon surrender of such
Senior Notes to the Paying Agent, and (ii) payments of interest shall be made, at the option of the Company, subject to such surrender where applicable, (A) by check mailed to the address of the Person entitled thereto as such address
shall appear in the Bond Register or (B) by wire transfer to registered Holders of at least $10,000,000 in principal amount of Senior Notes at such place and to such account at a banking institution in the United States as such Holders may

 TRUSTEE’S CERTIFICATE OF AUTHENTICATION 

This Senior Note is one of the Bonds of the series designated as Bonds of the Forty-Eighth Series referred to in the within-mentioned
Indenture. 
 Dated: 
  

			
	BOKF, N.A., As Trustee
		
	By:	 	 
		 	Authorized Signatory














 Reverse of Amended and Restated 3.50% Senior Note due June 15, 2025 

This Senior Note is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or more series under an Amended and
Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented by a Twenty-Fifth Supplemental Indenture, dated as of June 12, 2015, and as amended by the Thirtieth
Supplemental Indenture, dated as of July 1, 2020 (as so supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called the
“Indenture”), between the Company and BOKF, N.A., 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
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. This Senior Note is a
Bond within the meaning of the Indenture and is one of the Bonds of the forty-eighth series designated as the 3.50% Senior Notes due June 15, 2025 established by the Company under the Indenture. The acceptance of this Senior Note shall be
deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 
 The Senior Notes
will be secured by a series of first mortgage bonds (the “3.50% Collateral Mortgage Bonds due 2025”) delivered by the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental
Indenture, dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”).
Reference is made to the Indenture and the Mortgage Indenture for a description of the rights of the Trustee as holder of the 3.50% Collateral Mortgage Bonds due 2025, the property mortgaged and pledged, the nature and extent of the security and
rights of the holders of the first mortgage bonds under the Mortgage Indenture and the rights of the Company under the Mortgage Indenture and the terms and conditions upon which the Senior Notes are secured. 

Subject to the terms and conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional
Redemption”), in whole or in part, (a) at any time prior to March 15, 2025 (the date that is three months prior to the Maturity Date) at a Redemption Price equal to the greater of: 

(i)    100% of the principal amount of the Senior Notes to be redeemed; or 

(ii)    as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled
Payments of principal and interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date), calculated as if the Maturity Date of such Senior Notes was March 15, 2025 (the date
that is three months prior to the Maturity Date), discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 20 basis points, 

plus, in either of the above cases, accrued and unpaid interest thereon to but not including the Redemption Date; and (b) at any time on or after
March 15, 2025 (the date that is three months prior to the Maturity Date) at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 10 days
nor more than 60 days prior to the Redemption Date to each Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $1,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall
be conclusive and binding upon such Holder and upon all future Holders of this Senior Note and of any Senior Note 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 Senior Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 












 The Senior Notes 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, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note
of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except
the unredeemed portion of any Senior Note being redeemed in part. 
 Prior to due presentment of this Senior Note for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 This Senior Note 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
Senior Note, 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 Senior Note. 

All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.

 Reverse of Amended and Restated 3.50% Senior Note due June 15, 2025 

This Senior Note is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or more series under an Amended and
Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented by a Twenty-Fifth Supplemental Indenture, dated as of June 12, 2015, and as amended by the Thirtieth
Supplemental Indenture, dated as of July 1, 2020 (as so amended and supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called
the “Indenture”), between the Company and BOKF, N.A., 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
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. This Senior Note is a
Bond within the meaning of the Indenture and is one of the Bonds of the forty-eighth series designated as the 3.50% Senior Notes due June 15, 2025 established by the Company under the Indenture and initially issued in an aggregate principal
amount of $400,000,000 on June 12, 2015. As a result of the further issuance of $200,000,000 aggregate principal amount of Bonds of the forty-eighth series on November 5, 2015, the issued amount of Bonds of such series now totals
$600,000,000. The acceptance of this Senior Note shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 

The Senior Notes will be secured by a series of first mortgage bonds (the “3.50% Collateral Mortgage Bonds due 2025”) delivered by
the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental Indenture, dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and
The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”). Reference is made to the Indenture and the Mortgage Indenture for a description of the rights of the Trustee as holder of the 3.50%
Collateral Mortgage Bonds due 2023, the property mortgaged and pledged, the nature and extent of the security and rights of the holders of the first mortgage bonds under the Mortgage Indenture and the rights of the Company under the Mortgage
Indenture and the terms and conditions upon which the Senior Notes are secured. 
 Subject to the terms and conditions of the Indenture, the
Senior Notes are redeemable at the option of the Company (“Optional Redemption”), in whole or in part, (a) at any time prior to March 15, 2025 (the date that is three months prior to the Maturity Date) at a Redemption Price equal
to the greater of: 
 (i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and
interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date), calculated as if the Maturity Date of such Senior Notes was March 15, 2025 (the date that is three months prior
to the Maturity Date), discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 20 basis points, 












 plus, in either of the above cases, accrued and unpaid interest thereon to but not including the Redemption
Date; and (b) at any time on or after March 15, 2025 (the date that is three months prior to the Maturity Date) at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 10 days
nor more than 60 days prior to the Redemption Date to each Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $1,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall be conclusive and binding upon such Holder and upon all future
Holders of this Senior Note and of any Senior Note 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 Senior Note. 

As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is
registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 












 The Senior Notes 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, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note
of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except
the unredeemed portion of any Senior Note being redeemed in part. 
 Prior to due presentment of this Senior Note for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 This Senior Note 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
Senior Note, 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 Senior Note. 

All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.

 PACIFIC GAS AND ELECTRIC COMPANY, a corporation duly organized and existing under the laws of the State of
California (herein called the “Company,” which term includes any successor Person pursuant to the applicable provisions of the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., as
nominee for The Depository Trust Company, or registered assigns, the Principal Amount stated above on the Maturity Date stated above, and to pay interest thereon from and including the Original Issue Date stated above or, in the case of a 4.25%
Senior Note due March 15, 2046 issued upon the registration of transfer or exchange, from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on the Interest Payment
Dates set forth above and on the Maturity Date stated above, commencing March 15, 2016 at the rate of 4.25% per annum until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this 4.25% Senior Note due March 15, 2046 (this “Senior Note,” and together with all other 4.25% Senior Notes due
March 15, 2046, the “Senior Notes”) (or one or more Predecessor Bonds) is registered at the close of business on the Regular Record Date for such interest, which shall be the 15th day preceding such Interest Payment Date;
provided, however, that interest payable at the Maturity Date or on a Redemption Date will be paid to the Person to whom principal is payable. 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 Senior Note (or one or more Predecessor Bonds) 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 Senior Notes 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 the Indenture and any securities exchange, if any, on which the Senior Notes may be listed, and upon such notice as may be required by any such exchange, all as more fully provided in said Indenture. 

Payments of interest on this Senior Note will include interest accrued to but excluding the respective Interest Payment Dates. Interest
payments for this Senior Note shall be computed and paid on the basis of the 360-day year of twelve 30-day months and will accrue from November 5, 2015 or from the
most recent Interest Payment Date to which interest has been paid or duly provided for. In the event that any date on which interest is payable on this Senior Note (other than the Maturity Date) is not a Business Day then payment of the interest
payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable. If the
Maturity Date falls on a day that is not a Business Day, the payment of principal, premium, if any, 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.













 Payment of principal of, premium, if any, and interest on Senior 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 of, premium, if any, and interest on the Senior Notes represented by a Global Bond shall be

are no longer represented by a Global Bond, (i) payments of principal, premium, if any, and interest due on the Maturity Date or earlier redemption of such Senior Notes shall be made at the office of the Paying Agent upon surrender of such
Senior Notes to the Paying Agent, and (ii) payments of interest shall be made, at the option of the Company, subject to such surrender where applicable, (A) by check mailed to the address of the Person entitled thereto as such address
shall appear in the Bond Register or (B) by wire transfer to registered Holders of at least $10,000,000 in principal amount of Senior Notes at such place and to such account at a banking institution in the United States as such Holders may
designate in writing to the Trustee at least sixteen (16) days prior to the date for payment. 
 REFERENCE IS HEREBY MADE TO THE

This Senior Note is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or more series under an Amended and
Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented by a Twenty-Sixth Supplemental Indenture, dated as of November 5, 2015, and as amended by the Thirtieth
Supplemental Indenture, dated as of July 1, 2020 (as so amended and supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called
the “Indenture”), between the Company and BOKF, N.A., 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
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. This Senior Note is a
Bond within the meaning of the Indenture and is one of the Bonds of the forty-ninth series designated as the 4.25% Senior Notes due March 15, 2046 established by the Company under the Indenture. The acceptance of this Senior Note shall be
deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 
 The Senior Notes
will be secured by a series of first mortgage bonds (the “4.25% Collateral Mortgage Bonds due 2046”) delivered by the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental
Indenture, dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”).
Reference is made to the Indenture and the Mortgage Indenture for a description of the rights of the Trustee as holder of the 4.25% Collateral Mortgage Bonds due 2046, the property mortgaged and pledged, the nature and extent of the security and
rights of the holders of the first mortgage bonds under the Mortgage Indenture and the rights of the Company under the Mortgage Indenture and the terms and conditions upon which the Senior Notes are secured. 

Subject to the terms and conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional
Redemption”), in whole or in part, (a) at any time prior to September 15, 2045 (the date that is six months prior to the Maturity Date) at a Redemption Price equal to the greater of: 

(i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and
interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date), calculated as if the Maturity Date of such Senior Notes was September 15, 2045 (the date that is six months prior
to the Maturity Date), discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 25 basis points, 
 plus, in either of
the above cases, accrued and unpaid interest thereon to but not including the Redemption Date; and (b) at any time on or after September 15, 2045 (the date that is six months prior to the Maturity Date) at 100% of the principal amount of
the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 10 days
nor more than 60 days prior to the Redemption Date to each Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $2,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall
be conclusive and binding upon such Holder and upon all future Holders of this Senior Note and of any Senior Note 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 Senior Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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

 PACIFIC GAS AND ELECTRIC COMPANY, a corporation duly organized and existing under the laws of the State of
California (herein called the “Company,” which term includes any successor Person pursuant to the applicable provisions of the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., as
nominee for The Depository Trust Company, or registered assigns, the Principal Amount stated above on the Maturity Date stated above, and to pay interest thereon from and including the Original Issue Date stated above or, in the case of a 2.95%
Senior Note due March 1, 2026 issued upon the registration of transfer or exchange, from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on the Interest Payment
Dates set forth above and on the Maturity Date stated above, commencing September 1, 2016 at the rate of 2.95% per annum until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this 2.95% Senior Note due March 1, 2026 (this “Senior Note,” and together with all other 2.95% Senior Notes due
March 1, 2026, the “Senior Notes”) (or one or more Predecessor Bonds) is registered at the close of business on the Regular Record Date for such interest, which shall be the February 15th and August 15th preceding such Interest Payment Date; provided, however, that interest payable at the Maturity Date or on a Redemption Date will be paid to the
Person to whom principal is payable. 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 Senior Note
(or one or more Predecessor Bonds) 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 Senior Notes 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 the Indenture and any securities exchange, if any, on which the Senior Notes may be listed, and upon such notice as may be
required by any such exchange, all as more fully provided in said Indenture. 
 Payments of interest on this Senior Note will include
interest accrued to but excluding the respective Interest Payment Dates.

on this Senior Note (other than the Maturity Date) is not a Business Day then payment of the interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or payment in respect of any such
delay) with the same force and effect as if made on the date the payment was originally payable. If the Maturity Date falls on a day that is not a Business Day, the payment of principal, premium, if any, 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.

Notes are no longer represented by a Global Bond, (i) payments of principal, premium, if any, and interest due on the Maturity Date or earlier redemption of such Senior Notes shall be made at the office of the Paying Agent upon surrender of
such Senior Notes to the Paying Agent, and (ii) payments of interest shall be made, at the option of the Company, subject to such surrender where applicable, (A) by check mailed to the address of the Person entitled thereto as such address

 Reverse of Amended and Restated 2.95% Senior Note due March 1, 2026 

This Senior Note is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or more series under an Amended and
Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented by a Twenty-Seventh Supplemental Indenture, dated as of March 1, 2016, and as amended by the Thirtieth
Supplemental Indenture, dated as of July 1, 2020 (as so supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called the
“Indenture”), between the Company and BOKF, N.A., 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
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. This Senior Note is a
Bond within the meaning of the Indenture and is one of the Bonds of the fiftieth series designated as the 2.95% Senior Notes due March 1, 2026 established by the Company under the Indenture. The acceptance of this Senior Note shall be
deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 
 The Senior Notes
will be secured by a series of first mortgage bonds (the “2.95% Collateral Mortgage Bonds due 2026”) delivered by the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental
Indenture, dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”).
Reference is made to the Indenture and the Mortgage Indenture for a description of the rights of the Trustee as holder of the 2.95% Collateral Mortgage Bonds due 2026, the property mortgaged and pledged, the nature and extent of the security and
rights of the holders of the first mortgage bonds under the Mortgage Indenture and the rights of the Company under the Mortgage Indenture and the terms and conditions upon which the Senior Notes are secured. 

Subject to the terms and conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional
Redemption”), in whole or in part, (a) at any time prior to December 1, 2025 (the date that is three months prior to the Maturity Date) at a Redemption Price equal to the greater of: 

(i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal
and interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date), calculated as if the Maturity Date of such Senior Notes was December 1, 2025 (the date that is three months
prior to the Maturity Date), discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 20 basis points, 












 plus, in either of the above cases, accrued and unpaid interest thereon to but not including the Redemption
Date; and (b) at any time on or after December 1, 2025 (the date that is three months prior to the Maturity Date) at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 10 days
nor more than 60 days prior to the Redemption Date to each Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger
than $2,000 in principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this
Senior Note in part only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall be conclusive and binding upon such Holder and upon
all future Holders of this Senior Note and of any Senior Note 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 Senior Note. 

As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is
registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 












 The Senior Notes are issuable only in registered form without coupons in denominations of
$2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note
of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except
the unredeemed portion of any Senior Note being redeemed in part. 
 Prior to due presentment of this Senior Note for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 This Senior Note 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
Senior Note, 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 Senior Note. 

All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.

PACIFIC GAS AND ELECTRIC COMPANY, a corporation duly organized and existing under the laws of the State of California (herein called the

Indenture.

	BOKF, N.A., As Trustee

 Reverse of Amended and Restated 4.00% Senior Note due December 1, 2046 

This Senior Note is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or more series under an Amended and
Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented by a Twenty-Eighth Supplemental Indenture, dated as of December 1, 2016, and as amended by the
Thirtieth Supplemental Indenture, dated as of July 1, 2020 (as so amended and supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being
herein called the “Indenture”), between the Company and BOKF, N.A., 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 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. This
Senior Note is a Bond within the meaning of the Indenture and is one of the Bonds of the fifty-second series designated as the 4.00% Senior Notes due December 1, 2046 established by the Company under the Indenture. The acceptance of this Senior
Note shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 

The Senior Notes will be secured by a series of first mortgage bonds (the “4.00% Collateral Mortgage Bonds due 2046”) delivered by
the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental Indenture, dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and
The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”). Reference is made to the Indenture and the Mortgage Indenture for a description of the rights of the Trustee as holder of the 4.00%
Collateral Mortgage Bonds due 2046, the property mortgaged and pledged, the nature and extent of the security and rights of the holders of the first mortgage bonds under the Mortgage Indenture and the rights of the Company under the Mortgage
Indenture and the terms and conditions upon which the Senior Notes are secured. 
 Subject to the terms and conditions of the Indenture, the
Senior Notes are redeemable at the option of the Company (“Optional Redemption”), in whole or in part, (a) at any time prior to June 1, 2046 (the date that is six months prior to the Maturity Date) at a Redemption Price equal to
the greater of: 
 (i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and
interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date), calculated as if the Maturity Date of such Senior Notes was June 1, 2046 (the date that is six months prior to
the Maturity Date), discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 20 basis points, 












 plus, in either of the above cases, accrued and unpaid interest thereon to but not including the Redemption
Date; and (b) at any time on or after June 1, 2046 (the date that is six months prior to the Maturity Date) at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 10 days
nor more than 60 days prior to the Redemption Date to each Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $2,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall be conclusive and binding upon such Holder and upon all future
Holders of this Senior Note and of any Senior Note 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 Senior Note. 

As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is
registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 












 The Senior Notes are issuable only in registered form without coupons in denominations of
$2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note
of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except
the unredeemed portion of any Senior Note being redeemed in part. 
 Prior to due presentment of this Senior Note for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 This Senior Note 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
Senior Note, 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 Senior Note. 

All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.

 PACIFIC GAS AND ELECTRIC COMPANY, a corporation duly organized and existing under the laws of the State of

herein called the “Indenture”), between the Company and BOKF, N.A., 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 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. This
Senior Note is a Bond within the meaning of the Indenture and is one of the Bonds of the fifty-second series designated as the 4.00% Senior Notes due December 1, 2046 established by the Company under the Indenture and initially issued in an
aggregate principal amount of $400,000,000 on December 1, 2016. As a result of the further issuance of $200,000,000 aggregate principal amount of Bonds of the fifty-second series on March 10, 2017, the issued amount of Bonds of such series
now totals $600,000,000. The acceptance of this Senior Note shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 

The Senior Notes will be secured by a series of first mortgage bonds (the “4.00% Collateral Mortgage Bonds due 2046”) delivered by
the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental Indenture, dated as of July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and

Indenture and the terms and conditions upon which the Senior Notes are secured. 
 Subject to the terms and conditions of the Indenture, the
Senior Notes are redeemable at the option of the Company (“Optional Redemption”), in whole or in part, (a) at any time prior to June 1, 2046 (the date that is six months prior to the Maturity Date) at a Redemption Price equal to
the greater of: 
 (i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and
interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date), calculated as if the Maturity Date of such Senior Notes was June 1, 2046 (the date that is six months prior to
the Maturity Date), discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 20 basis points, 












 plus, in either of the above cases, accrued and unpaid interest thereon to but not including the Redemption
Date; and (b) at any time on or after June 1, 2046 (the date that is six months prior to the Maturity Date) at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 10 days
nor more than 60 days prior to the Redemption Date to each Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar

Date is deposited with the Paying Agent or the Trustee on or prior to the Redemption Date, from and after such Redemption Date such Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $2,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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

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 Senior Note shall be conclusive and binding upon such Holder and upon all future
Holders of this Senior Note and of any Senior Note 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 Senior Note. 

As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is
registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 












 The Senior Notes are issuable only in registered form without coupons in denominations of
$2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note
of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except
the unredeemed portion of any Senior Note being redeemed in part. 
 Prior to due presentment of this Senior Note for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 This Senior Note 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
Senior Note, 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,

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 Senior Note.

CUSIP No: 694308HS9
	  	Principal Amount: $400,000,000

 PACIFIC GAS AND ELECTRIC COMPANY, a corporation duly organized and existing under the laws of the State of
California (herein called the “Company,” which term includes any successor Person pursuant to the applicable provisions of the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., as
nominee for The Depository Trust Company, or registered assigns, the Principal Amount stated above on the Maturity Date stated above, and to pay interest thereon from and including the Original Issue Date stated above or, in the case of a 3.30%
Senior Note due March 15, 2027 issued upon the registration of transfer or exchange, from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on the Interest Payment
Dates set forth above and on the Maturity Date stated above, commencing September 15, 2017 at the rate of 3.30% per annum until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this 3.30% Senior Note due March 15, 2027 (this “Senior Note,” and together with all other 3.30% Senior Notes due
March 15, 2027, the “Senior Notes”) (or one or more Predecessor Bonds) is registered at the close of business on the Regular Record Date for such interest, which shall be the March 1st and September 1st preceding such Interest Payment
Date; provided, however, that interest payable at the Maturity Date or on a Redemption Date will be paid to the Person to whom principal is payable. 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 Senior Note (or one or more Predecessor Bonds) 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 Senior Notes 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 the Indenture and any securities exchange, if any, on which the Senior Notes may be listed, and upon such notice as may be required by any such exchange, all as more fully provided in said Indenture. 

Payments of interest on this Senior Note will include interest accrued to but excluding the respective Interest Payment Dates. Interest
payments for this Senior Note shall be computed and paid on the basis of the 360-day year of twelve 30-day months and will accrue from March 10,
2017 or from the most recent Interest Payment Date to which interest has been paid or duly provided for. In the event that any date on which interest is payable on this Senior Note (other than the Maturity Date) is not a Business Day then payment of
the interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally
payable. If the Maturity Date falls on a day that is not a Business Day, 












 
the payment of principal, premium, if any, 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. 

Payment of principal of, premium, if any, and interest on Senior 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 of, premium, if any, and interest on the Senior Notes represented by a Global Bond shall be made by wire transfer of immediately available funds
to the Holder of such Global Bond, provided that, in the case of payments of principal and premium, if any, such Global Bond is first surrendered to the Paying Agent. If any of the Senior Notes are no longer represented by a Global Bond,
(i) payments of principal, premium, if any, and interest due on the Maturity Date or earlier redemption of such Senior Notes shall be made at the office of the Paying Agent upon surrender of such Senior Notes to the Paying Agent, and
(ii) payments of interest shall be made, at the option of the Company, subject to such surrender where applicable, (A) by check mailed to the address of the Person entitled thereto as such address shall appear in the Bond Register or
(B) by wire transfer to registered Holders of at least $10,000,000 in principal amount of Senior Notes at such place and to such account at a banking institution in the United States as such Holders may designate in writing to the Trustee at
least sixteen (16) days prior to the date for payment. 
 REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS SENIOR NOTE SET
FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE. 
 Unless
the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Senior Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

 Reverse of Amended and Restated 3.30% Senior Note due March 15, 2027 

This Senior Note is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or more series under an Amended and
Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as previously supplemented and as further supplemented by a Twenty-Ninth Supplemental Indenture, dated as of March 10, 2017, and as amended by the Thirtieth
Supplemental Indenture (as so amended and supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called the “Indenture”),
between the Company and BOKF, N.A., 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 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. This Senior Note is a Bond within the
meaning of the Indenture and is one of the Bonds of the fifty-third series designated as the 3.30% Senior Notes due March 15, 2027 established by the Company under the Indenture. The acceptance of this Senior Note shall be deemed to constitute
the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 
 The Senior Notes will be secured by a
series of first mortgage bonds (the “3.30% Collateral Mortgage Bonds due 2027”) delivered by the Company to the Trustee for the benefit of the Holders of the Senior Notes, issued pursuant to the Second Supplemental Indenture, dated as of
July 1, 2020 to the Indenture of Mortgage, dated as of June 19, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (as so supplemented, the “Mortgage Indenture”). Reference is made to the
Indenture and the Mortgage Indenture for a description of the rights of the Trustee as holder of the 3.30% Collateral Mortgage Bonds due 2027, the property mortgaged and pledged, the nature and extent of the security and rights of the holders of the
first mortgage bonds under the Mortgage Indenture and the rights of the Company under the Mortgage Indenture and the terms and conditions upon which the Senior Notes are secured. 

Subject to the terms and conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional
Redemption”), in whole or in part, (a) at any time prior to December 15, 2026 (the date that is three months prior to the Maturity Date) at a Redemption Price equal to the greater of: 

(i) 100% of the principal amount of the Senior Notes to be redeemed; or 

(ii) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and
interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date), calculated as if the Maturity Date of such Senior Notes was December 15, 2026 (the date that is three months
prior to the Maturity Date), discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate, plus 15 basis points, 












 plus, in either of the above cases, accrued and unpaid interest thereon to but not including the Redemption
Date; and (b) at any time on or after December 15, 2026 (the date that is three months prior to the Maturity Date) at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon 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 Senior Notes, 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 an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 10 days
nor more than 60 days prior to the Redemption Date to each Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar
amount has not been determined as of the date such notice is being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption Price of all Senior Notes (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 Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $2,000 in
principal amount may be redeemed in part but only in integral multiples of $1,000. 
 In the event of redemption of this Senior Note in part
only, a new Senior Note or Senior Notes 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 Senior Note 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 Senior Note when due. 

If an Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33% 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 Senior Note shall be conclusive and binding upon such Holder and upon all future
Holders of this Senior Note and of any Senior Note 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 Senior Note. 

As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is
registrable in the Bond Register, upon surrender of this Senior Note 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 Senior Note 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 Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 












 The Senior Notes are issuable only in registered form without coupons in denominations of
$2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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 Senior Note
of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of the Senior Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except
the unredeemed portion of any Senior Note being redeemed in part. 
 Prior to due presentment of this Senior Note for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 This Senior Note 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
Senior Note, 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 Senior Note. 

All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.
