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

ARTICLE I 
 SERIES UUU
BONDS 
 Section 1: There is hereby created, for issuance under the Original Indenture as supplemented by the
said Supplemental Indentures (including this Sixty-Ninth Supplemental Indenture), a series of bonds designated Series UUU, due 2050, each of which shall bear the descriptive title “First Mortgage Bonds, Series UUU, due 2050” (herein
sometimes referred to as “Series UUU Bonds”), and the form thereof shall contain suitable provisions with respect to the matters hereinafter in this Section specified. The Series UUU Bonds shall mature on April 15, 2050 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 UUU 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 UUU Bond set forth on Exhibit A hereto (the “Form of Bond”) and by the applicable
provisions of the Indenture. In addition, April 7, 2020 shall be an interest payment date for the Series UUU 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 UUU 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 UUU 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 UUU Bonds shall be dated as in Section 9 of Article II of the Indenture provided with respect to registered bonds without coupons. 

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

The Series UUU Bonds shall otherwise be of such terms, provisions, tenor and form as provided in this Sixty-Ninth Supplemental Indenture. 

Section 2: The Series UUU 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 Sixty-Ninth 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 UUU 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 $400,000,000 aggregate principal amount of Series UUU Bonds. The Company may, from time to time,
without notice to or the consent of the registered holders of the Series UUU Bonds but upon and subject to the terms and provisions of the Indenture, increase the principal amount of the Series UUU Bonds under the Indenture and issue such increased
principal amount, or any portion thereof. Any additional Series UUU 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 UUU Bonds previously issued and shall form a single series of bonds under the Indenture with the previously issued Series UUU Bonds. 

Section 3: The Series UUU 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 UUU Bonds shall be substantially in the form set forth on the Form of Bond. In addition, the Series UUU 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 UUU 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 UUU 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 UUU 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 UUU 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
UUU 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 UUU 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 UUU 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 UUU 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 UUU 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 UUU 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 UUU 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 UUU Bonds. 
 (3) Subject to Clause (2) above, any exchange or transfer of a Global
Security for other Series UUU Bonds may be made in whole or in part, and all definitive Series UUU 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 UUU Bond authenticated and delivered upon registration of transfer of, or in
exchange for or in lieu of, a Global Security or any portion thereof, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such bond is registered in the name of a person other than the depositary for such
Global Security or a nominee thereof. 

  
 12 













 (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

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 UUU Bonds may be exchanged without a service charge for a like aggregate principal amount of such Series UUU 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 UUU Bonds, including Series UUU 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 UUU 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 UUU Bonds, including Series UUU 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 UUU 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 3.320% FIRST MORTGAGE BOND, SERIES UUU, DUE 2050] 

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 UUU 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 Sixty-Ninth
Supplemental Indenture (the “Sixty-Ninth Supplemental Indenture”) dated as of April 7, 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 UUU Bonds as to such
security, and the terms and conditions upon which the Series UUU 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 UUU Bond is one of a series of Series UUU Bonds and is sometimes referred to as “this bond.” 

Interest on the Series UUU 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 UUU 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 October 15, 2049 (the “Par Call Date”), the Company may at the Company’s option redeem the
Series UUU Bonds, at any time in whole or from time to time in part, at a redemption price (the “Redemption Price”) for any redemption date (a “Redemption Date”) equal to the greater of the following amounts: (a)
100% of the principal amount of the Series UUU 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 UUU 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 UUU 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 30 basis points, as determined by the Independent Investment Banker (as defined below), plus, in each case, accrued and unpaid interest on the Series
UUU 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 UUU 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 UUU Bonds being redeemed, plus accrued and unpaid interest on the Series UUU Bonds being redeemed to the Redemption Date. Notwithstanding the foregoing, installments of interest on Series UUU 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 UUU Bonds as of the close of business on the relevant record date according to the
terms of the Series UUU 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. 

  
 A-3 













 Notice of any redemption will be mailed at least 30 days, but not more than 60 days, before
the Redemption Date to each registered holder of the Series UUU Bonds to be redeemed. Once notice of redemption is mailed, the Series UUU 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 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 UUU Bonds or portions thereof called for redemption. The Company will pay the Redemption Price and any accrued interest once the Series UUU Bonds are surrendered for
redemption. If only a portion of any Series UUU Bonds is redeemed, the Trustee will deliver new Series UUU 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 UUU Bonds to be redeemed on such Redemption Date (assuming the Series UUU 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 UUU Bonds (assuming the Series UUU 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) BMO Capital Markets Corp., Mizuho
Securities USA LLC, RBC Capital Markets, LLC and Wells Fargo Securities, LLC (or their respective affiliates which are Primary Treasury Dealers (as defined below)), and their respective successors, provided, however, that if any of the foregoing
shall cease to be a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”), the Company will substitute therefor another Primary Treasury Dealer; (B) one Primary Treasury Dealer selected by BBVA
Securities Inc. and its successors; and (C) 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 UUU Bonds, (a) the Series UUU Bonds to be redeemed shall be selected as provided in the Indenture and, in the case of Series UUU Bonds represented by a Global Security (as
defined in the Sixty-Ninth 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 UUU 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. 

  
 A-4 













 As more fully provided in and subject to the provisions of the Indenture, the Series UUU
Bonds are also subject to redemption on any date, under certain circumstances specified in the second paragraph of Section 13 of Article XI of the Indenture in case of the disposition or taking (among other things) of certain properties of the
Company, at 100% of the principal amount thereof, together with accrued interest on the Series UUU bonds being redeemed to the date of redemption. 

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 UUU Bonds are issued in definitive certificated form under
the circumstances set forth in clause (2) of Section 4 of Article I of the Sixty-Ninth 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 UUU 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 UUU Bonds are issued in definitive certificated form under the circumstances set forth in clause (2) of Section 4 of Article I of the Sixty-Ninth 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 UUU 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 UUU 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.

 This Series UUU Bond shall be governed by and construed in accordance with the laws of the
State of California, without regard (to the extent permitted by applicable law) to conflicts of laws principles thereof.
