or similar fund for the benefit of the bonds of any particular series; 
 The Company does further covenant and agree with the Trustee as
follows: 
 ARTICLE I 

SERIES OOO BONDS 

Section 1: There is hereby created, for issuance under the Original Indenture as supplemented by the said Supplemental Indentures
(including this Sixty-Third Supplemental Indenture), a series of bonds designated Series OOO, due 2017, each of which shall bear the descriptive title “Floating Rate First Mortgage Bonds, Series OOO, due 2017” (herein sometimes referred to
as “Series OOO Bonds”), and the form thereof shall contain suitable provisions with respect to the matters hereinafter in this Section specified. The Series OOO Bonds shall mature on March 9, 2017 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 OOO 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 OOO Bond set forth on Exhibit A hereto (the “Form of Bond”) and by the applicable
provisions of the Indenture. In addition, March 12, 2015 shall be an Interest Payment Date for the Series OOO 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 OOO Bonds shall be payable at the corporate trust office of the Trustee in the Borough of Manhattan, City and County of New York, State of New York. The Series OOO Bonds shall be dated as
in Section 9 of Article II of the Indenture provided with respect to registered bonds without coupons. 
 The Series OOO Bonds shall
further be redeemable, exchangeable, transferable and otherwise have the terms set forth in the Form of Bond. 
 The Series OOO Bonds shall
otherwise be of such terms, provisions, tenor and form as provided in this Sixty-Third Supplemental Indenture. 
 Section 2: The
Series OOO 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-Third 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 OOO 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 OOO 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 OOO Bonds shall be substantially in the form set forth on the Form of Bond. In addition, the Series OOO 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 

  
 10 

 
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 OOO 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 OOO 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 OOO 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 OOO 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 OOO 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 OOO Bonds in such form and denominations as are required by or pursuant to the Indenture, and in an aggregate principal amount equal to the 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 OOO 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 OOO 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 OOO 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 date interest is due (an “Interest Payment Date”) for such bond and before the opening of business at that place of payment on the
next 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 OOO
Bonds. The Company may, in its sole discretion, pay interest on definitive Series OOO Bonds by check mailed to the addresses of the persons entitled to such payment or by wire transfer to bank accounts in the United States designated in writing to
the Trustee at least 15 days before the applicable Interest Payment Date by the persons entitled to such payment. 
 (3) Subject to
Clause (2) above, any exchange or transfer of a Global Security for other Series OOO Bonds may be made in whole or in part, and all Series OOO 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. 

  
 11 

 (4) Every Series OOO 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 OOO 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 OOO 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 OOO Bonds may be exchanged without a service charge for a like aggregate principal amount of such Series OOO 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 Borough of Manhattan, City and County of New York, State of New York, 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 OOO Bonds, including Series OOO Bonds issued in definitive form, may be presented for payment, registration, transfer and exchange
as provided therein or in the Indenture. Such office or agency shall be the 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 OOO 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

 12 

 Section 3: In order to facilitate the filing of this Sixty-Third Supplemental

 Section 5: To the extent any provision in

 Section 6: The Original Indenture, as heretofore amended and
supplemented, insofar as it applies to the Series OOO Bonds, this Sixty-Third Supplemental Indenture and the Series OOO 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

 SAN DIEGO GAS & ELECTRIC COMPANY, a corporation organized and existing under the laws of the State of California
(hereinafter called the “Company”, which term shall include any successor corporation, as defined in the Indenture hereinafter referred to), for value received, hereby promises to pay to
                             [If this bond is issued as a global security, insert CEDE & CO.
in the foregoing space] or registered assigns, the principal sum of                             
dollars in lawful money of the United States of America, on the ninth day of March, 2017 (the “Maturity Date”), and to pay interest thereon from March 12, 2015 (the “Original Issue Date”) or from the most
recent date to which interest has been paid or duly provided for quarterly in arrears on March 9, June 9, September 9 and December 9 in each year (each, an “Interest Payment Date”), beginning on June 9,
2015, and on the Maturity Date at the Applicable Rate (as defined below) as in effect from time to time, until the principal hereof is paid or made available for payment, provided, that if any Interest Payment Date (other than the Interest Payment
Date falling on the Maturity Date) is not a Series OOO Business Day (as defined on the reverse hereof), such Interest Payment Date will be moved to, and will be, the immediately succeeding Series OOO Business Day, except that if such immediately
succeeding Series OOO Business Day is in the immediately succeeding calendar month, such Interest Payment Date (other than the Interest Payment Date falling on the Maturity Date) will be moved to, and will be, the immediately preceding Series OOO
Business Day. If the Maturity Date is not a Series OOO Business Day, the Company will pay interest and principal due on the Maturity Date on the immediately succeeding day that is a Series OOO Business Day as if such payment were made on the date
such payment was originally due, and no interest will accrue on the amounts so payable for the period from and after the Maturity Date to the immediately succeeding Series OOO Business Day. 

The term “Applicable Rate” means a per annum interest rate determined as follows: the Applicable Rate for the period from and
including the Original Issue Date to but excluding the Interest Payment Date falling in June 2015 will be equal to the 3 Month LIBOR Rate (as defined on the reverse hereof), determined as of the second London Banking Day (as defined on the reverse
hereof) immediately preceding the Original Issue Date, plus 0.200% per year, and the Applicable Rate will be reset on each Interest Payment Date (each of these dates is called an “Interest Reset Date”), beginning with the
Interest Reset Date falling in June 2015, and will be equal to the 3 Month LIBOR Rate, determined as of the second London Banking Day immediately preceding the applicable Interest Reset Date, plus 0.200% per year. The interest rate on this
Series OOO Bond (as defined on the reverse hereof) will in no event be higher than the maximum rate permitted by California law as the same may be modified by United States law of general application. 

Interest payable on any Interest Payment Date or on the Maturity Date shall be the amount of interest accrued from, and including, the
immediately preceding Interest Payment Date in respect of which interest has been paid or duly provided for on this Series OOO Bond (or from and including the Original Issue Date if no interest has been paid or duly provided for on this Series OOO
Bond) to, but not including, such Interest Payment Date or the Maturity Date, as the case may be. 

  
 A-1 

 The interest so payable on any Interest Payment Date will be paid to the person in whose name
this Series OOO Bond is registered at the close of business on the 15th calendar day, whether or not a Series OOO Business Day, immediately preceding such Interest Payment Date; provided that interest payable on the Maturity Date shall be paid to
the person to whom principal is paid. 
 The principal of (and premium, if any) and interest on this bond (as defined on the reverse hereof)
will be paid at the corporate trust office of U.S. Bank National Association, or its successor trustee under the Indenture, in the Borough of Manhattan, City and County of New York, State of New York, that the Company maintains for such purpose;
provided that, if this bond is in definitive certificated form and registered in the name of a holder other than a depositary, or its nominee, the Company may, in its sole discretion, pay interest on this bond by check mailed to the address of the
person entitled to such payment or by wire transfer to a bank account in the United States designated in writing to the Trustee at least 15 days before the applicable Interest Payment Date by the person entitled to such payment. Notwithstanding the
foregoing, so long as the holder of this bond is a depositary, or its nominee, payment of the principal of (and premium, if any) and interest on this bond will be made by wire transfer of immediately available funds. 

The provisions of this bond are continued on the reverse hereof and such continued provisions shall for all purposes have the same effect as
though fully set forth at this place.

NATIONAL ASSOCIATION, as Trustee under the Indenture, or its successor thereunder, shall have signed the certificate of authentication endorsed hereon.

 [REVERSE SIDE OF FLOATING RATE FIRST MORTGAGE BOND, SERIES OOO, DUE 2017] 

This bond is one of a duly authorized issue of bonds of the Company, known as its Floating Rate First Mortgage Bonds, of the series and designation indicated
on the face hereof (the “Series OOO 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-Third Supplemental
Indenture dated as of March 12, 2015 (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 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 OOO Bonds as to such security, and the terms and conditions upon which the Series OOO 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 OOO Bond is one of a series of Series
OOO Bonds and is sometimes referred to as this “bond.” 
 In connection with the issuance of the Series OOO Bonds, the Company has
entered into a Calculation Agent Agreement dated as of March 12, 2015 (as the same may be amended or supplemented from time to time and including any successor agreement thereto, the “Calculation Agreement”) with U.S. Bank
National Association, as calculation agent (in such capacity herein called the “Calculation Agent,” which term includes any successor thereto under the Calculation Agreement). 

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 OOO 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. 

The 3 Month LIBOR Rate will be determined by the Calculation Agent in accordance with the following provisions: 

“3 Month LIBOR Rate” means the rate for deposits in U.S. dollars for the 3-month period commencing on the applicable Interest
Reset Date which appears on Reuters Screen LIBOR01 Page (as defined below) at approximately 11:00 a.m., London time, on the second London Banking Day (as defined below) prior to such Interest Reset Date (the second London Banking Day prior to any
Interest Reset Date being referred to as an “Interest Determination Date”). If this rate does not appear on Reuters Screen LIBOR01 Page, the Calculation Agent will determine the rate on the basis of the rates at which deposits in
U.S. dollars are offered by four major banks in the London interbank market selected by the Calculation Agent at approximately 11:00 a.m., London time, on the applicable Interest Determination Date to prime banks in the London interbank market for a
period of three months commencing on that Interest Reset Date and in a principal amount equal to an amount not less than U.S. $1,000,000 that is representative for a single transaction in such market at such time. In such case, the Calculation Agent
will request the principal London office of each of the aforesaid major banks to provide a quotation of such rate. If at least two such quotations are provided, the rate for that Interest Reset Date will be the arithmetic mean of the quotations,
and, if fewer than two quotations are provided as requested, the rate for that Interest Reset Date will be the arithmetic mean of the rates quoted by three major banks in New York City selected by the Calculation Agent, at approximately 11:00 a.m.,
New York City time, on the applicable Interest Determination Date for loans in U.S. dollars to leading European banks for a period of three months commencing on that Interest Reset Date and in a principal amount equal to an amount not less than U.S.
$1,000,000 that is representative for a single transaction in 

  
 A-4 

 
such market at such time; provided, however, that if the banks selected as aforesaid by the Calculation Agent are not quoting such rates as mentioned in this sentence, the 3 Month LIBOR Rate
commencing as of such Interest Reset Date will remain the 3 Month LIBOR Rate determined as of the Interest Determination Date for the immediately preceding Interest Reset Date. Solely for purposes of this paragraph, the term “Interest Reset
Date” shall be deemed to include the Original Issue Date. 
 The term “London Banking Day” means any day on which
dealings in U.S. dollars are transacted in the London interbank market. 
 The term “Reuters Screen LIBOR01 Page” means the
display designated on page “LIBOR01” on Reuters (or such other page as may replace the LIBOR01 page on that service or any successor service for the purpose of displaying London interbank offered rates for U.S. dollar deposits of major
banks). 
 The term “Series OOO Business Day” means any day (1) that is a business day in The City of New York and
(2) that is also a London Banking Day. As used in clause (1) of 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. 
 The Calculation Agent will, upon the request of the registered holder
of this Series OOO Bond, provide the interest rate then in effect. All calculations made by the Calculation Agent in the absence of manifest error shall be conclusive for all purposes and binding on the Company and the holder of this Series OOO
Bond. The Company may appoint a successor Calculation Agent with the written consent of the Trustee. 
 All percentages resulting from any
calculation of the interest rate on this Series OOO Bond will be rounded, if necessary, to the nearest one-hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (for example, 9.876545% (or
..09876545) being rounded to 9.87655% (or .0987655) and 9.876544% (or .09876544) being rounded to 9.87654% (or .0987654)), and all dollar amounts in or resulting from any such calculation will be rounded to the nearest cent (with one-half cent being
rounded upwards). 
 Interest on the Series OOO Bonds will be calculated on the basis of a 360-day year and the actual number of days in the
applicable period. 
 As more fully provided in and subject to the provisions of the Indenture, the Series OOO Bonds are 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 of certain properties of the Company, at 100% of the principal amount
thereof, together with accrued interest thereon to the date of redemption. 
 The Company may, from time to time, without notice to or the
consent of the holders of the Series OOO Bonds, increase the principal amount of the Series OOO Bonds under the Indenture and issue such increased principal amount, or any portion thereof. Any additional Series OOO 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 OOO Bonds previously issued and shall
form a single series with the previously issued Series OOO 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 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 OOO 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 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 

  
 A-5 

 
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 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 OOO 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.

sometimes referred to as “Series PPP Bonds”), and the form thereof shall contain suitable provisions with respect to the matters hereinafter in this Section specified. The Series PPP Bonds shall mature on February 1, 2022 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 PPP Bonds shall bear interest at the rate and from the date, shall be expressed to mature as to unpaid
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 PPP Bond set forth on Exhibit A hereto (the “Form of Bond”)
and by the applicable provisions of the Indenture. In addition, March 12, 2015 shall be an interest payment date for the Series PPP Bonds for purposes of Section 9 of Article II of the Indenture, provided that no interest or
principal shall be payable on such date. The principal and premium, if any, and interest on the Series PPP Bonds shall be payable at the corporate trust office of the Trustee in the Borough of Manhattan, City and County of New York, State of New
York. The Series PPP Bonds shall be dated as in Section 9 of Article II of the Indenture provided with respect to registered bonds without coupons. 

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

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

 Section 2: The Series PPP 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-Fourth 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 PPP 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 PPP 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 PPP Bonds shall be substantially in the form set forth on the Form of Bond. In addition, the Series PPP
Bonds may be issuable in 

  
 10 

 
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 PPP 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 PPP 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 PPP 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 PPP 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 PPP 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 PPP 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 unpaid 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 PPP 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, an aggregate principal amount of definitive Series PPP Bonds of authorized denominations equal to the
aggregate unpaid principal amount of 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
PPP 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 date principal and interest is due (a “Series PPP
Payment Date”) for such bond and before the opening of business at that place of payment on the next Series PPP Payment Date, or (ii) any special record date for the payment of principal and/or interest for such bond which was not
punctually paid or duly provided for on any Series PPP Payment Date and before the opening of business at such place of payment on the related proposed date for the payment of such principal and/or interest, as the case may be, principal and
interest (in the case described in clause (i) above) or principal and/or interest, as applicable (in the case described in clause (ii) above), shall not be payable on such Series PPP Payment Date or proposed date for payment, as the case
may be, in respect of such definitive bond, but shall be payable on the Series PPP Payment Date or proposed date for payment, as the case may be, only to the person to whom principal and interest (in the case described in clause (i) above) or
principal and/or interest, as applicable (in the case described in clause (ii) above), in respect of such portion of such Global Security shall be payable in accordance with the provisions of the Indenture and the Series PPP Bonds. The Company
may, in its sole 

  
 11 

 
discretion, pay principal of and interest on definitive Series PPP Bonds by check mailed to the addresses of the persons entitled to such payment or by wire transfer to bank accounts in the
United States designated in writing to the Trustee at least 15 days before the applicable Series PPP Payment Date (including, without limitation, the Series PPP Payment Date falling on the maturity date of the Series PPP Bonds) by the persons
entitled to such payment. 
 (3)Subject to Clause (2) above, any exchange or transfer of a Global Security for other Series PPP
Bonds may be made in whole or in part, and all Series PPP 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 PPP 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 PPP
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 PPP 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 PPP Bonds may be exchanged without a service charge for Series PPP Bonds of other authorized denomination or denominations in an aggregate principal amount equal to the aggregate unpaid principal amount
of the Series PPP Bonds surrendered for exchange; 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 Borough of Manhattan, City and County of New York, State of New York, 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 PPP Bonds, including Series PPP Bonds issued in definitive form, may be presented for payment, registration, transfer and exchange
as provided therein or in the Indenture. Such office or agency shall be the 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 PPP 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.

(                     dollars) each, payable semiannually on each Series PPP Payment Date (as defined below), commencing on the first day of
August, 2015 (provided that the amount of the remaining such installments of principal shall be reduced in the event of a partial redemption of the Series PPP Bonds (as defined on the reverse hereof) as provided on the reverse hereof under the
caption “Optional Redemption” and adjusted in the event of the issuance of additional Series PPP Bonds as provided on the reverse hereof under the caption “Additional Series PPP Bonds”; and provided, further, that if the final
such installment of principal on this bond (as defined on the reverse hereof) is not equal to the unpaid principal amount of this bond on February 1, 2022 (the “Maturity Date”), then such final installment of principal shall be

of doubt as reduced by the amortization of principal as described above in this sentence) at the rate of 1.914% per annum, accruing from March 12, 2015, in like lawful money, payable semiannually in arrears on the first day of February and
August (each, a “Series PPP Payment Date”) of each year, commencing August 1, 2015, until the Company’s obligation with respect to the payment of such principal (and premium, if any) shall be discharged as provided in the
Indenture hereinafter mentioned. Installments of principal of and interest on this bond that are due and payable on any Series PPP Payment Date (including the Series PPP Payment Date falling on the Maturity Date) will be payable to the persons in
whose names the Series PPP bonds are registered at the close of business on the January 15 or July 15, as the case may be, immediately preceding such Series PPP Payment Date. Any payment of less than the full amount of principal and
interest due on a Series PPP Payment Date will first be applied to pay accrued and unpaid interest and second to pay principal. The Maturity Date of this bond is February 1, 2022 and the final installment of principal of this bond will be paid
on the Maturity Date. 
 The principal of (and premium, if any) and interest on this bond will be paid at the corporate trust office of U.S.

 [REVERSE SIDE OF 1.914% AMORTIZING FIRST MORTGAGE BOND, SERIES PPP, DUE 2022] 

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 PPP 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-Fourth Supplemental Indenture
dated as of March 12, 2015 (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 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 PPP Bonds as to such security, and the terms and conditions upon which the Series PPP 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 PPP Bond is one of a series of Series PPP Bonds
and is sometimes referred to as “this bond.” 
 Interest on the Series PPP 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 PPP 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, the reduction of any installment of principal, the extension of the Maturity Date or any Series PPP Payment Date, 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; provided that, notwithstanding the foregoing, the amount of remaining installments of principal on this bond shall be reduced in the event of a partial redemption of the Series PPP Bonds as provided below under the
caption “Optional Redemption” and adjusted in the event of the issuance of additional Series PPP Bonds as provided below under the caption “Additional Series PPP Bonds.” 

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. 

Optional Redemption 
 All or a portion of
the Series PPP 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 PPP Bonds will be redeemed pursuant to this paragraph (the “Redemption
Price”) on the date fixed for such redemption (the “Redemption Date”) will be equal to the greater of the following amounts: (a) 100% of the unpaid principal amount of the Series PPP 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 PPP Bonds being redeemed on that Redemption Date (not including any portion of any payments of accrued and unpaid
interest to the Redemption Date) discounted to the Redemption Date on a semiannual basis at the Adjusted Treasury Rate (as defined below) plus 12.5 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. 
 A partial redemption of the Series PPP Bonds, whether pursuant to the
provisions set forth in the preceding paragraph or, as provided below, under certain circumstances specified in the second paragraph of Section 13 of Article XI of the Indenture in the case of the disposition or taking of certain properties of
the Company, will result in each remaining installment of principal on the Series PPP Bonds (for the avoidance of doubt, excluding any installments of principal that are payable on any Series PPP Payment Dates falling on or prior to the applicable
redemption date) being reduced in the same proportion as the aggregate unpaid principal amount of the Series PPP Bonds is reduced by such partial redemption. For purposes of the foregoing calculation, (A) if the applicable

  
 A-4 

 
redemption date falls on a Series PPP Payment Date, then the proportion by which the aggregate unpaid principal amount of the Series PPP Bonds is reduced by such partial redemption shall be
calculated after giving effect to the installment of principal that is paid on such Series PPP Payment Date and (B) if the amount of the semi-annual installment of principal on any outstanding Series PPP Bond resulting from such calculation is
not an integral multiple of $1,000, such amount shall be rounded downwards to the nearest integral multiple of $1,000. 
 Notwithstanding
the provisions of the second preceding paragraph, installments of interest and installments of principal payable on the Series PPP Bonds that are due and payable on Series PPP Payment Dates falling on or prior to a Redemption Date will be payable on
such Series PPP Payment Dates to the registered holders of such Series PPP Bonds as of the close of business on the relevant record dates according to the terms of the Series PPP 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 PPP Bonds to be redeemed. Once notice of redemption is mailed, the Series PPP 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 PPP Bonds or portions thereof called for redemption. The Company will pay the Redemption Price and any accrued interest once
the Series PPP Bonds are surrendered for redemption. If only a portion of any Series PPP Bonds is redeemed, the Trustee will deliver new Series PPP 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 PPP Bonds to be redeemed on such Redemption 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 PPP Bonds. 

“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) Citigroup Global Markets Inc. and RBC Capital Markets, 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 Mitsubishi UFJ Securities (USA), Inc. and its successors; (C) one Primary Treasury Dealer selected by The Williams Capital Group, L.P. and its successors; and (D) 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

  
 A-5 

 
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 PPP 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 PPP 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 of certain properties of the Company, at 100% of the unpaid principal amount thereof, together with
accrued interest thereon to the date of redemption. 
 Additional Series PPP Bonds 

The Company may, from time to time, without notice to or the consent of the holders of the bonds, increase the principal amount of the Series
PPP Bonds under the Indenture and issue such increased principal amount, or any portion thereof. Any additional Series PPP 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, the first payment date and the amount of the semiannual installments of principal) as the Series PPP Bonds previously issued and shall form a single series with the
previously issued Series PPP Bonds. An increase in the principal amount of the Series PPP Bonds as a result of the issuance of additional Series PPP Bonds will result in each remaining installment of principal on the Series PPP Bonds (for the
avoidance of doubt, excluding any installments of principal that are payable on any Series PPP Payment Dates falling on or prior to the date on which any such additional Series PPP Bonds are issued) being increased in the same proportion as the
aggregate unpaid principal amount of the Series PPP Bonds is increased by the issuance of such additional Series PPP Bonds. For purposes of the foregoing calculation, (A) if the date on which any such additional Series PPP Bonds are issued
falls on a Series PPP Payment Date, then the proportion by which the aggregate unpaid principal amount of the Series PPP Bonds is increased by the issuance of such additional Series PPP Bonds shall be calculated after giving effect to the
installment of principal that is paid on such Series PPP Payment Date and (B) if the amount of the semi-annual installment of principal on any outstanding Series PPP Bond resulting from such calculation is not an integral multiple of $1,000,
such amount shall be rounded downwards to the nearest integral multiple of $1,000.
