benefit of the bonds of any particular series; 
 The Company does further covenant and agree with the Trustee as follows: 

ARTICLE I 
 SERIES RRR
BONDS 
 Section 1: There is hereby created, for issuance under the Original Indenture as supplemented by the said
Supplemental Indentures (including this Sixty-Sixth Supplemental Indenture), a series of bonds designated Series RRR, due 2047, each of which shall bear the descriptive title “First Mortgage Bonds, Series RRR, due 2047” (herein sometimes
referred to as “Series RRR Bonds”), and the form thereof shall contain suitable provisions with respect to the matters hereinafter in this Section specified. The Series RRR Bonds shall mature on June 1, 2047 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 RRR Bonds shall bear interest at the rate and from the date, shall be expressed to mature as to principal, and shall be
payable as to principal and premium, if any, and interest at such place or places and in such money, all as provided in the form of Series RRR Bond set forth on Exhibit A hereto (the “Form of Bond”) and by the applicable
provisions of the Indenture. In addition, June 8, 2017 shall be an interest payment date for the Series RRR 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 RRR Bonds shall be payable at the corporate trust office of the Trustee in the City and County of Los Angeles, State of California and, if Series RRR 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 in the Borough of Manhattan, City and County of New York, State of New York that the Company maintains for such
purpose. The Series RRR Bonds shall be dated as in Section 9 of Article II of the Indenture provided with respect to registered bonds without coupons. 

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

  
 9 








 The Series RRR Bonds shall otherwise be of such terms, provisions, tenor and form as provided in
this Sixty-Sixth Supplemental Indenture. 
 Section 2: The Series RRR 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-Sixth 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 RRR Bonds, which may be executed by the Company and authenticated and delivered by the Trustee and secured by the Indenture as from time to time in
effect, is limited only to the extent provided in Section 1 of Article II of the Original Indenture. 
 Section 3: The
Series RRR 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 RRR Bonds shall be substantially in the form set forth on
the Form of Bond. In addition, the Series RRR 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 which is issued to a depositary or a nominee thereof for such series
(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 definitive Series RRR Bonds shall be numbered in such manner as the Company shall at any
time or from time to time determine. 
 Section 4: In the event the Series RRR Bonds are issued as a Global Security the
following provisions, in addition to the provisions of the Indenture, shall apply: 
 (1) Each Global Security authenticated under the
Indenture shall be registered in the name of the depositary designated for such Global Security or a nominee thereof and delivered to such depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single
bond for all purposes of this Supplemental Indenture. 
 (2) Notwithstanding any other provision in this Supplemental Indenture, no
Global Security may be exchanged in whole or in part for Series RRR 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 Securities and a successor depositary has not been appointed by the Company within 90 days of receipt by
the Company of such notification, (B) if at any time the depositary ceases to be a clearing agency registered under the Exchange Act at a time when the depositary is required to be so registered to act as such depositary and no successor
depositary shall have been appointed by the Company within 90 days after it became aware of such cessation, (C) the Company, in its sole discretion, executes and delivers to the Trustee a written order signed in the name of the Company by its
Chairman of the Board, its President or a Vice President, and by its Treasurer, an Assistant Treasurer, its Secretary or an Assistant Secretary to the effect that such Global Securities 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 RRR Bonds. If any of the events described in clauses (A) through (D) of the preceding sentence occur, the beneficial
owners of interests in the Global Securities will be entitled to exchange those interests for definitive Series RRR 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 RRR 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 (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 RRR 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 RRR 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 RRR 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 payment 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
and before the opening of business at such place of payment on the related proposed date for the payment of such 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 RRR Bonds. 

  
 10 








 (3) Subject to Clause (2) above, any exchange or transfer of a Global Security for
other Series RRR Bonds may be made in whole or in part, and all Series RRR 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 RRR Bond authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a
Global Security or any portion thereof, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such bond is registered in the name of a person other than the depositary for such Global Security or a nominee
thereof. 
 (5) Unless otherwise specified as contemplated by Section 1 of Article I of this Supplemental Indenture for the
Series RRR Bonds evidenced thereby, every Global Security authenticated and delivered hereunder shall bear a legend in substantially the following form: 

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

Section 5: The Series RRR 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 RRR Bonds may be exchanged without a service charge for a like aggregate principal amount of such Series RRR 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 RRR Bonds, including Series RRR 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 RRR 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 RRR Bonds, including Series RRR 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. 

  
 11 








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

ARTICLE II 

MISCELLANEOUS PROVISIONS 

Section 1: This instrument is executed and shall be construed as an indenture supplemental to the Original Indenture and shall
form a part thereof and, as supplemented by this Sixty-Sixth Supplemental Indenture, the Original Indenture as heretofore supplemented and amended is hereby confirmed. 

Section 2: All terms used in this Sixty-Sixth Supplemental Indenture shall be taken to have meaning as in the Original Indenture,
as heretofore supplemented and amended, except terms which may be otherwise expressly defined herein and in cases where the context clearly indicates otherwise. 

Section 3: In order to facilitate the filing of this Sixty-Sixth Supplemental Indenture, the same may be executed in several
counterparts, each of which, when so executed, shall be deemed to be an original, but such counterparts shall constitute but one and the same instrument. 

Section 4: All of the covenants, stipulations, promises and agreements in this Sixty-Sixth Supplemental Indenture by or on behalf
of the Company shall bind its successors and assigns, whether so expressed or not. 
 Section 5: To the extent any provision in
this Sixty-Sixth Supplemental Indenture conflicts with any provision in the Indenture, the provisions of this Sixty-Sixth Supplemental Indenture shall govern; provided, however, that in the event such conflict would require bondholder
consent, the terms and provisions of the Indenture shall govern. 
 Section 6: The Original Indenture, as heretofore amended and
supplemented, insofar as it applies to the Series RRR Bonds, this Sixty-Sixth Supplemental Indenture and the Series RRR Bonds 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; provided, that, notwithstanding the foregoing, the creation, perfection and enforcement of any mortgage or lien on real property or improvements thereon or fixtures
attached thereto under the Original Indenture, as heretofore amended and supplemented, insofar as it applies to the Series RRR Bonds, or this Sixty-Sixth Supplemental Indenture shall be governed by and construed in accordance with the laws of the
State where such real property or improvements thereon or fixtures attached thereto, as the case may be, are located, without regard (to the extent permitted by applicable law) to conflicts of laws principles thereof.

 [REVERSE SIDE OF 3.750% FIRST MORTGAGE BOND, SERIES RRR, DUE 2047] 

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 RRR 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-Sixth
Supplemental Indenture (the “Sixty-Sixth Supplemental Indenture”) dated as of June 8, 2017 (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 RRR Bonds as to such
security, and the terms and conditions upon which the Series RRR Bonds may be issued under the Indenture and are secured. The principal hereof may be declared or may become due on the conditions, in the manner and at the time set forth in the
Indenture, upon the happening of a completed default as in the Indenture provided. This Series RRR Bond is one of a series of Series RRR Bonds and is sometimes referred to as “this bond.” 

Interest on the Series RRR 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 RRR 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. 

All or a portion of the Series RRR Bonds may be redeemed at the Company’s option at any time or from time to time pursuant to this
paragraph. The price at which the Series RRR Bonds will be redeemed pursuant to this paragraph (the “Redemption Price”) on any date fixed for such redemption (a “Redemption Date”) will be equal to (A) in the
case of any Redemption Date prior to December 1, 2046 (the “Par Call Date”), the greater of the following amounts: (a) 100% of the principal amount of the Series RRR Bonds being redeemed on the Redemption Date; or
(b) the sum of the present values of the remaining scheduled payments of principal and interest on the Series RRR Bonds being redeemed on that Redemption Date (not including any portion of any payments of accrued and unpaid interest to the
Redemption Date) that would be due if the Series RRR Bonds matured, and accrued and unpaid interest was payable, on the Par Call Date, discounted to the Redemption Date on a semiannual basis at the Adjusted Treasury Rate (as defined below) plus 15
basis points, as determined by the Independent Investment Banker (as defined below), plus, in each case, accrued and unpaid interest thereon to the Redemption Date, or (B) in the case of any Redemption Date on or after the Par Call Date, 100%
of the principal amount of the Series RRR Bonds to be redeemed on the Redemption Date, plus accrued and unpaid interest thereon to the Redemption Date. Notwithstanding the foregoing, installments of interest on Series RRR Bonds that are due and
payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on those Interest Payment Dates to the registered holders of such Series RRR Bonds as of the close of business on the relevant record dates according to the
terms of the Series RRR 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 Redemption Date to each registered holder of
the Series RRR Bonds to be redeemed. Once notice of redemption is mailed, the Series RRR 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. 

  
 A-3 








 Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date
interest will cease to accrue on the Series RRR Bonds or portions thereof called for redemption. The Company will pay the Redemption Price and any accrued interest once the Series RRR Bonds are surrendered for redemption. If only a portion of any
Series RRR Bonds is redeemed, the Trustee will deliver new Series RRR 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 an actual or interpolated maturity comparable to the remaining term of the Series RRR Bonds to be
redeemed on such Redemption Date (assuming the Series RRR 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 RRR Bonds (assuming the Series RRR 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 Dealers” means, with respect
to any Redemption Date, (A) Credit Suisse Securities (USA) LLC and Goldman Sachs & Co. 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 CastleOak Securities, L.P. and its successors; (C) one Primary Treasury Dealer selected by Credit Agricole Securities (USA) Inc. and its successors; (D) one Primary Treasury Dealer selected by SMBC Nikko Securities
America, Inc. and its successors; and (E) any other Primary Treasury Dealer(s) selected by the Company. 
 “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. 

In the event that the Company elects to redeem only a portion of the Series RRR Bonds, the bonds to be redeemed shall be selected as provided
in the Indenture and, in the case of bonds represented by a global security, in accordance with the procedures of The Depository Trust Company (or its successor as depositary). 

As more fully provided in and subject to the provisions of the Indenture, the Series RRR 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 thereon to the date of redemption. 

  
 A-4 








 The Company may, from time to time, without notice to or the consent of the holders of the Series
RRR Bonds, increase the principal amount of the Series RRR Bonds under the Indenture and issue such increased principal amount, or any portion thereof. Any additional Series RRR Bonds so issued shall have the same form and terms (other than the
offering price, the date of issuance and, under certain circumstances, the date from which interest thereon shall begin to accrue and the first payment date) as the Series RRR Bonds previously issued and shall form a single series with the
previously issued Series RRR Bonds. 
 This bond is transferable as prescribed in the Indenture by the registered owner hereof in person, or
by his duly authorized attorney, at the corporate trust office of the Trustee in the City and County of Los Angeles, State of California, and, if Series RRR Bonds are issued in definitive certificated form under the circumstances set forth in clause
(2) of Section 4 of Article I of the Sixty-Sixth 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 of the same series and principal amount will be issued to the transferee in exchange therefor as provided in the Indenture, upon payment of any tax or taxes or other governmental charges
required to be paid by the Company by reason of such transfer. 
 The registered owner of any Series RRR Bond, at the option of such holder,
may surrender the same, accompanied by a written instrument of transfer in form approved by the Company duly executed by the registered owner, at the corporate trust office of the Trustee in the City and County of Los Angeles, State of California
and, if Series RRR Bonds are issued in definitive certificated form under the circumstances set forth in clause (2) of Section 4 of Article I of the Sixty-Sixth 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 herein or in respect hereof or of said Indenture, against any incorporator, or any past or future stockholder,
officer or director, as such, of the Company or of any predecessor or successor corporation, either directly or through the Company, or through any such predecessor or successor corporation, or through any receiver or a trustee in bankruptcy,
whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived
and released, as more fully provided in the Indenture. 
 This Series RRR 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.
