 The Company does further covenant and agree with the Trustee as follows:

 ARTICLE I 
 SERIES
VVV BONDS 
 Section 1: There is hereby created, for issuance under the Original Indenture as
supplemented by the said Supplemental Indentures (including this Seventieth Supplemental Indenture), a series of bonds designated Series VVV, due 2030, each of which shall bear the descriptive title “First Mortgage Bonds, Series VVV, due
2030” (herein sometimes referred to as “Series VVV Bonds”), and the form thereof shall contain suitable provisions with respect to the matters hereinafter in this Section specified. The Series VVV Bonds shall mature on
October 1, 2030 and shall be issued in denominations of $1,000 and integral multiples thereof as the Company may from time to time execute and deliver. The Series VVV Bonds shall bear interest at the rate and from the date, shall mature as to
principal, and shall be payable as to principal and premium, if any, and interest at such place or places and in such money, all as provided in the form of Series VVV Bond set forth on Exhibit A hereto (the “Form of Bond”)
and by the applicable provisions of the Indenture. In addition, September 28, 2020 shall be an interest payment date for the Series VVV Bonds for purposes of Section 9 of Article II of the Indenture, provided that no interest shall
be payable on such date. The principal and premium, if any, and interest on the Series VVV Bonds shall be payable at the office or agency maintained by the Company for such purpose (initially the corporate trust office of the Trustee) in the City
and County of Los Angeles, State of California and, if Series VVV Bonds are issued in definitive certificated form under the circumstances set forth in clause (2) of Section 4 of this Article I, at the office or agency maintained by the
Company for such purpose in the Borough of Manhattan, City and County of New York, State of New York. The Series VVV Bonds shall be dated as in Section 9 of Article II of the Indenture provided with respect to registered bonds without
coupons. 
 The Series VVV Bonds shall further be redeemable, exchangeable, transferable and otherwise have the terms set
forth in the Form of Bond. 
 The Series VVV Bonds shall otherwise be of such terms, provisions, tenor and form as provided
in this Seventieth Supplemental Indenture. 
 Section 2: The Series VVV Bonds shall be executed,
authenticated and delivered in accordance with the provisions and shall be entitled to the protection and security of the Original Indenture, as supplemented by this Seventieth Supplemental Indenture and the other supplemental indentures, and shall
be subject to all of the terms, conditions and covenants and limitations thereof. The aggregate principal amount of the Series VVV Bonds, which may be executed by the Company and authenticated and delivered by the Trustee and secured by the
Indenture as from time to time in effect, is limited only to the extent provided in Section 1 of Article II of the Original Indenture. The Company has authorized the issuance and sale on the date hereof of $800,000,000 aggregate principal
amount of Series VVV Bonds. The Company may, from time to time, without notice to or the consent of the registered holders of the Series VVV Bonds but upon and subject to the terms and provisions of the Indenture, increase the principal amount of
the Series VVV Bonds under the Indenture and issue such increased principal amount, or any portion thereof. Any additional Series VVV Bonds so issued shall have the same form and terms (other than offering price, the date of original issuance and,
under certain circumstances, the date from which interest thereon shall begin to accrue and the first Interest Payment Date (as defined below)) as the Series VVV Bonds previously issued and shall form a single series of bonds under the Indenture
with the previously issued Series VVV Bonds. 
 Section 3: The Series VVV Bonds shall be issued
only as fully registered bonds without coupons. The fully registered bonds without coupons and the certificate of authentication to be endorsed on all Series VVV Bonds shall be substantially in the form set forth on the Form of Bond. In addition,
the Series VVV Bonds may be issuable in whole or in part in the form of one or more securities that evidence all or part of the bonds of such series and are registered in the name of a depositary (as defined below) or a nominee thereof for such
series (each, a “Global Security”) and, in such case, the Board of Directors of the Company (or an authorized officer designated by the Board of Directors of the Company) shall appoint a clearing agency registered under the
Securities Exchange Act of 1934, as amended (the “Exchange Act”), designated to act as depositary (a “depositary”) for such Global Securities; the initial depositary so appointed is The Depository Trust Company. The
definitive Series VVV Bonds shall be numbered in such manner as the Company shall at any time or from time to time determine. 

  
 11 













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

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

  
 12 













 
of, and shall be, a Global Security, unless such bond is registered in the name of a person other than the depositary for such Global Security or a nominee thereof. 

(5)    Every Global Security authenticated and delivered hereunder shall bear a legend in
substantially the following form: 
 THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS
REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART FOR A SECURITY REGISTERED, AND NO TRANSFER OF THIS SECURITY IN WHOLE OR IN PART MAY BE REGISTERED, IN THE NAME OF ANY PERSON OTHER
THAN SUCH DEPOSITARY OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE. ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY OTHER PERSON IS WRONGFUL, INASMUCH AS THE REGISTERED OWNER
HEREOF HAS AN INTEREST HEREIN. 
 Section 5: The Series VVV Bonds may contain or have imprinted
thereon such provisions or specifications not inconsistent with the Indenture as may be required to comply with the rules of any stock exchange or any federal or state authority or commission, or to comply with usage with respect thereto, and may
bear such other appropriate endorsements or notations as are authorized or permitted by the Indenture. 

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

Section 7: The Company shall maintain in the City and County of Los Angeles, State of California,
and in such other place or places as the Company may designate at any time or from time to time, an office or agency where Series VVV Bonds, including Series VVV Bonds issued in definitive certificated form, may be presented for payment,
registration, transfer and exchange as provided therein or in the Indenture. Without limitation to the foregoing, if Series VVV Bonds are issued in definitive certificated form under the circumstances set forth in clause (2) of Section 4
of this Article I, the Company shall also maintain in the Borough of Manhattan, City and County of New York, State of New York, an office or agency where Series VVV Bonds, including Series VVV Bonds issued in definitive certificated form, may be
presented for payment, registration, transfer and exchange as provided therein or in the Indenture. Such office or agency in the City and County of Los Angeles, State of California, and any such office or agency in the Borough of Manhattan, City and
County of New York, State of New York, shall be a corporate trust office of the Trustee unless and until the Company shall designate another office or agency by notice in writing delivered to the Trustee. 

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

 [REVERSE SIDE OF 1.700% FIRST MORTGAGE BOND, SERIES VVV, DUE 2030] 

This bond is one of a duly authorized issue of bonds of the Company, known as its First Mortgage Bonds, of the series and
designation indicated on the face hereof (the “Series VVV Bonds”), all issued and to be issued under and equally secured by a Mortgage and Deed of Trust dated July 1, 1940, and indentures supplemental thereto, including the
Seventieth Supplemental Indenture (the “Seventieth Supplemental Indenture”) dated as of September 28, 2020 (which Mortgage and Deed of Trust, as so amended and supplemented and as the same may be further amended or supplemented
from time to time, is herein called the “Indenture”), executed by the Company to U.S. Bank National Association, as successor trustee (herein called, together with its successors in such capacity, the “Trustee”), to
which Indenture reference is hereby made for a description of the property mortgaged, pledged, hypothecated and in which a security interest was granted, the nature and extent of the security, the rights of the holders of the Series VVV Bonds as to
such security, and the terms and conditions upon which the Series VVV Bonds may be issued under the Indenture and are secured. The principal hereof may be declared or may become due on the conditions, in the manner and at the time set forth in the
Indenture, upon the happening of a completed default (as defined in the Indenture) as in the Indenture provided. This Series VVV Bond is one of a series of Series VVV Bonds and is sometimes referred to as “this bond.” 

Interest on the Series VVV Bonds will be calculated on the basis of a 360-day year
consisting of twelve 30-day months. 
 With the consent of the Company and to the
extent permitted by and as provided in the Indenture, the rights and obligations of the Company or of the holders of the Series VVV Bonds, or the terms and provisions of the Indenture or of any indentures supplemental thereto, may be modified or
altered by the affirmative vote of the holders of the percentage of principal amount of bonds required by the Indenture; provided, however, that without the consent of the holder hereof no such modification or alteration shall permit, among
other things, the reduction of the principal or premium, if any, or the extension of the maturity of the principal of this bond, or the reduction of the rate of interest hereon, or any other modification of the terms of payment of such principal or
premium, if any, or interest. 
 The Company, the Trustee, any paying agent, any registrar, and any depositary may deem and
treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment of or on account of the principal hereof and premium, if any, and interest hereon and for all other purposes and shall not be
affected by any notice to the contrary. 
 Prior to July 1, 2030 (the “Par Call Date”), the Company
may at the Company’s option redeem the Series VVV Bonds, at any time in whole or from time to time in part, at a redemption price for any redemption date equal to the greater of the following amounts: (a) 100% of the principal amount of the
Series VVV Bonds being redeemed on that redemption date; or (b) the sum of the present values of the remaining scheduled payments of principal and interest on the Series VVV Bonds being redeemed on that redemption date (not including any
portion of any payments of accrued and unpaid interest to that redemption date) that would be due if the Series VVV Bonds matured, and accrued and unpaid interest was payable, on the Par Call Date, discounted to that redemption date on a semiannual
basis at the Adjusted Treasury Rate (as defined below) plus 20 basis points, as determined by the Independent Investment Banker (as defined below), plus, in each case, accrued and unpaid interest on the Series VVV Bonds being redeemed to that
redemption date. On and after the Par Call Date, the Company may at the Company’s option redeem the Series VVV Bonds, at any time in whole or from time to time in part, at a redemption price equal to 100% of the principal amount of the Series
VVV Bonds being redeemed, plus accrued and unpaid interest on the Series VVV Bonds being redeemed to the redemption date. Notwithstanding the foregoing, installments of interest on Series VVV Bonds that are due and payable on any Interest Payment
Date falling on or prior to a redemption date will be payable on that Interest Payment Date to the registered holders of such Series VVV Bonds as of the close of business on the relevant record date according to the terms of the Series VVV Bonds and
the Indenture. The redemption price will, if applicable, be calculated on the basis of a 360-day year consisting of twelve 30-day months. 

Notice of any redemption will be mailed at least 30 days, but not more than 60 days, before the applicable redemption date to
each registered holder of the Series VVV Bonds to be redeemed. Once notice of redemption is mailed, the Series VVV Bonds called for redemption will become due and payable on the redemption date and at the applicable redemption price, plus accrued
and unpaid interest to the redemption date, provided that the Company may 

  
 A-3 













 
rescind any notice of redemption by notice given not less than five days prior to the proposed redemption date. Redemption will not be conditional upon receipt by the Trustee of monies sufficient
to pay the redemption price. 
 Unless the Company defaults in payment of the redemption price, on and after the redemption
date interest will cease to accrue on the Series VVV Bonds or portions thereof called for redemption. The Company will pay the redemption price and any accrued interest once the Series VVV Bonds are surrendered for redemption. If only a portion of
any Series VVV Bonds is redeemed, the Trustee will deliver new Series VVV Bonds for the remaining portion without charge. 

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

“Comparable Treasury Issue” means, with respect to any redemption date, the United States Treasury security
selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the Series VVV Bonds to be redeemed on such redemption date (assuming the Series VVV Bonds matured on the Par Call Date) that would be utilized,
at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Series VVV Bonds (assuming the Series VVV Bonds matured on the Par
Call Date). 
 “Comparable Treasury Price” means, with respect to any redemption date, (A) the average
of the Reference Treasury Dealer Quotations for such redemption date, or (B) if only one Reference Treasury Dealer Quotation is received, such quotation. 

“Independent Investment Banker” means, with respect to any redemption date, one of the Reference Treasury
Dealers appointed by the Company to act as the “Independent Investment Banker.” 
 “Reference Treasury
Dealer Quotation” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a
percentage of its principal amount) quoted in writing to the Company by such Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third business day preceding such redemption date. As used in the preceding sentence,
“business day” means any day (other than a Saturday or Sunday) on which banking institutions in The City of New York are not authorized or obligated by law or executive order to remain closed. 

“Reference Treasury Dealers” means, with respect to any redemption date, (A) Barclays Capital Inc., BNP
Paribas Securities Corp. and BofA Securities, Inc. (or their respective affiliates which are Primary Treasury Dealers (as defined below)), or their respective successors, as applicable, provided, however, that if any of the foregoing shall cease to
be a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”), the Company will substitute therefor another Primary Treasury Dealer; (B) one Primary Treasury Dealer selected by MUFG Securities
Americas Inc. or its successor, as applicable; (C) one Primary Treasury Dealer selected by PNC Capital Markets LLC or its successor, as applicable; and (D) any other Primary Treasury Dealer(s) selected by the Company. 

In the event that the Company elects to redeem only a portion of the outstanding Series VVV Bonds, (a) the Series VVV
Bonds to be redeemed shall be selected as provided in the Indenture and, in the case of Series VVV Bonds represented by a Global Security (as defined in the Seventieth Supplemental Indenture), in accordance with the procedures of The Depository
Trust Company (or its successor as depositary) and (b) in the case of any Series VVV Bond being redeemed in part, the principal amount redeemed must be $1,000 or an integral multiple of $1,000 and the remaining principal amount must be an
authorized denomination. 
 As more fully provided in and subject to the provisions of the Indenture, the Company will
redeem the Series VVV Bonds in the event of the sale, release, taking by eminent domain or purchase by public authority of property constituting or including all or substantially all of the electric distribution system of the Company in the City of
San 

  
 A-4 













 
Diego, all as more fully provided in the second paragraph of Section 13 of Article XI of the Indenture, in which event the Company will redeem Series VVV Bonds (in the principal amount
determined pursuant to the second paragraph of Section 13 of Article XI of the Indenture) at the same redemption price (including accrued and unpaid interest on the Series VVV Bonds or portions thereof being redeemed) that would have been
payable on the applicable redemption date had the Company redeemed Series VVV Bonds on such date pursuant to the optional redemption provisions set forth above. 

This bond is transferable as prescribed in the Indenture by the registered owner hereof in person, or by his duly authorized
attorney, at the office or agency maintained by the Company for that purpose (initially the corporate trust office of the Trustee) in the City and County of Los Angeles, State of California, and, if Series VVV Bonds are issued in definitive
certificated form under the circumstances set forth in clause (2) of Section 4 of Article I of the Seventieth Supplemental Indenture, at the office or agency maintained by the Company for such purpose in the Borough of Manhattan, City and
County of New York, State of New York, upon surrender and cancellation of this bond and thereupon a new registered bond or bonds of the same series of authorized denominations and of a like aggregate principal amount, will be issued to the
transferee in exchange herefor as provided in the Indenture, upon payment of any tax or taxes or other governmental charges required to be paid by the Company by reason of such transfer. 

The registered owner of any Series VVV Bond, at the option of such holder, may surrender the same, accompanied by a written
instrument of transfer in form approved by the Company duly executed by the registered owner, at the office or agency maintained by the Company for that purpose (initially the corporate trust office of the Trustee) in the City and County of Los
Angeles, State of California and, if Series VVV Bonds are issued in definitive certificated form under the circumstances set forth in clause (2) of Section 4 of Article I of the Seventieth Supplemental Indenture, at the office or agency
maintained by the Company for such purpose in the Borough of Manhattan, City and County of New York, State of New York, for cancellation in exchange for another or other registered bonds of the said series of higher or lower authorized denominations
of an aggregate principal amount equal to the aggregate principal amount of the bond or bonds so surrendered and bearing interest as provided in Section 9 of Article II of the Indenture, and upon payment of any tax or taxes or other
governmental charges required to be paid by the Company by reason of such exchange and subject to the terms and conditions specified in the Indenture, and thereupon the Company shall execute and deliver to the Trustee and the Trustee shall
authenticate and deliver such other bonds to such registered owner at its office or at such office or agency of the Company, at the option of such registered owner. 

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

In any case where any Interest Payment Date, any redemption date or the final maturity date of the Series VVV Bonds shall not
be a Business Day at any Place of Payment (as those terms are defined in the next sentence), then payment of the principal, premium, if any, and interest due on such Interest Payment Date, redemption date or final maturity date, as the case may be,
need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on such Interest Payment Date, redemption date or final maturity date, as
the case may be, and, in that case, no interest will accrue on the amount payable for the period from and after such Interest Payment Date, redemption date or final maturity date, as the case may be. As used in the immediately preceding sentence,
“Place of Payment” means the City and County of Los Angeles, State of California and any other place or places where the Company may from time to time maintain an office or agency where Series VVV Bonds may be presented for payment, and
“Business Day,” when used with respect to any Place of Payment, means a day other than (i) a Saturday or a Sunday or (ii) a day on which banking institutions in that Place of Payment are authorized or obligated by law or
executive order to remain closed.
