 I, the undersigned

(successor in trust to JPMorgan Chase Bank), as Trustee (the “Trustee”). Terms used herein and not otherwise defined herein shall have the meanings assigned to them in the Indenture, unless the context clearly requires otherwise. Based

 1. The terms and conditions of the Securities of the series described in this
Officer’s Certificate are as follows (the numbered subdivisions set forth in this Paragraph 1 corresponding to the numbered subdivisions of Section 301 of the Indenture): 

(1) The Securities of the twenty-fifth series to be issued under the Indenture shall be designated as the “1.85% General Mortgage Bonds,
Series Y, due 2021” (the “Bonds”), as set forth in the Twenty-Fourth Supplemental Indenture, dated as of the date hereof, between the Company and the Trustee. 

(2) The Trustee shall authenticate and deliver the Bonds for original issue on May 18, 2016 (the “Issue Date”) in the aggregate
principal amount of $300,000,000, upon a Company Order for the authentication and delivery thereof and satisfaction of Section 401 of the Indenture. 

(3) Interest on the Bonds shall be payable to the Persons in whose names such Securities are registered at the close of business on the Regular
Record Date for such interest (as specified in (5) below), except as otherwise expressly provided in the form of such Securities attached hereto as Exhibit A. 

(4) The Bonds shall mature and the principal thereof shall be due and payable together with all accrued and unpaid interest thereon on
June 1, 2021. 
 (5) The Bonds shall bear interest at the rate of 1.85% per annum. Interest shall accrue on the Bonds from the
Issue Date, or the most recent date to which interest has been paid or duly provided for. The Interest Payment Dates for the Bonds shall be June 1 and December 1 in each year commencing December 1, 2016, and the Regular Record Dates
with respect to the Interest Payment Dates for the Bonds shall be the May 15 and November 15, respectively, immediately preceding each Interest Payment Date (whether or not a Business Day); provided however that interest payable at
maturity, upon redemption or when principal is otherwise due will be payable to the Holder to whom principal is payable. 






 (6) The Corporate Trust Office of The Bank of New York Mellon Trust Company, National Association
in New York, New York shall be the place at which (i) the principal of and premium, if any, and interest on the Bonds shall be payable, (ii) registration of transfer of the Bonds may be effected, (iii) exchanges of the Bonds may be

Officer’s Certificates, its principal office in Houston, Texas as any such place or itself as the Security Registrar; provided, however, that there shall be only a single Security Registrar for each series of Bonds. 

(7) The Bonds shall be redeemable, at the option of the Company, at any time or from time to time, in whole or in part, on any date prior to
May 1, 2021 at a price equal to the greater of (i) 100% of the principal amount of the Bonds to be redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Bonds to be
redeemed that would be due if the Bonds matured on May 1, 2021 but for the redemption (not including any portion of such payments of interest accrued to the Redemption Date) discounted to the date of redemption (the “Redemption Date”)
on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 12.5 basis points plus, in each case, accrued and unpaid interest on the principal amount being redeemed to the Redemption Date.
On or after May 1, 2021, the Company may redeem the Bonds, at any time or from time to time, in whole or in part, by paying 100% of the principal amount of Bonds to be redeemed plus accrued and unpaid interest on the principal amount being
redeemed to the Redemption Date. 
 “Treasury Rate” means, with respect to any Redemption Date the yield, under the
heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15 (519)” or any successor publication which is published weekly by the Board of Governors
of the Federal Reserve System and which establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable
Treasury Issue (if no maturity is within three months before or after the remaining life (as defined below), yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate
will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such
yields, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated by the Independent Investment Banker using 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. The Treasury Rate will be calculated by the Independent Investment Banker on the third Business Day preceding the Redemption Date. 






 “Comparable Treasury Issue” means the U.S. Treasury security selected
by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term (“remaining life”) of the Bonds to be redeemed (assuming for this purpose that the Bonds matured on May 1, 2021) 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 Bonds. 

“Comparable Treasury Price” means (1) the average of four Reference Treasury Dealer Quotations for such
Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

 “Independent Investment Banker” means Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC or Wells
Fargo Securities, LLC, as specified by the Company, or if these firms are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing selected by the Company. 

“Reference Treasury Dealer” means each of (1) Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC
and Wells Fargo Securities, LLC, 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 of America (a “Primary Treasury Dealer”),
the Company will substitute therefor another Primary Treasury Dealer and (2) any other Primary Treasury Dealer selected by the Company after consultation with the Independent Investment Banker. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date,
the average, as determined by the Independent Investment Banker, 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 Independent Investment Banker at
5:00 p.m., New York City time, on the third business day preceding such Redemption Date. 
 The Trustee, at the written
direction of the Company, will send a notice of redemption to each holder of Bonds to be redeemed by first-class mail (or in accordance with the procedures of The Depository Trust Company with respect to Bonds registered in the name of
Cede & Co.) at least 30 and not more than 60 days prior to the date fixed for redemption. Unless the Company defaults on payment of the redemption price, interest will cease to accrue on the Bonds or portions thereof called for redemption
on the Redemption Date. If fewer than all of the Bonds are to be redeemed, the Trustee will select, not more than 60 days prior to the Redemption Date, the particular Bonds or portions thereof for redemption from the outstanding Bonds not previously
called by such method as the Trustee deems fair and appropriate. The Trustee may select for redemption Bonds and portions of Bonds in amounts of $1,000 or whole multiples of $1,000. In the case of a partial redemption of Bonds registered in the name
of Cede & Co, the Bonds to be redeemed will be determined in accordance with the procedures of The Depository Trust Company.

that the Depositary is unwilling or unable to continue as Depositary for such Global Security, the Depositary defaults in the performance of its duties as Depositary, or the Depositary has ceased to be a clearing agency registered under the Exchange
Act, in each case, unless the Company has approved a successor Depositary 






 
within 90 days, (B) the Company in its sole discretion determines that such Global Security will be so exchangeable or transferable or (C) there shall exist such circumstances, if any,

specified above in each year, commencing on December 1, 2016, and at Maturity, at the Interest Rate per annum specified above, until the principal hereof is paid or duly provided for. The interest so payable, and paid or duly provided for, on

not so paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice of which shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at
any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said
Indenture. 
 Payment of the principal of and premium, if any, on this Security and interest hereon at Maturity shall be made upon presentation of this
Security at the office of the Corporate Trust Administration of The Bank of New York Mellon Trust Company, National Association, located in New York, New York or at such other office or agency as may be designated for such purpose by the Company
from time to time. Payment of interest on this Security (other than interest at Maturity) shall be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register, except that if such Person

aforesaid, shall be made in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts. 

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and issuable in one or more
series under and equally secured by a General Mortgage Indenture, dated as of October 10, 2002, as supplemented and amended (such Indenture as originally executed and delivered and as supplemented or amended from time to time thereafter,
together with any constituent instruments establishing the terms of particular Securities, being herein called the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, National Association (successor in trust to
JPMorgan Chase Bank), trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the
property mortgaged, pledged and held in trust, the nature and extent of the security and the respective rights, limitations of rights, duties and immunities of the Company, the Trustee and the Holders of the Securities thereunder and of the terms
and conditions upon which the Securities are, and are to be, authenticated and delivered and secured. The acceptance of this Security shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of
the Indenture. This Security is one of the series designated above. 
 If any Interest Payment Date, any Redemption Date or the Stated Maturity shall not be
a Business Day (as hereinafter defined), payment of the amounts due on this Security on such date may be made on the next succeeding Business Day; and, if such payment is made or duly provided for on such Business Day, no interest shall accrue on
such amounts for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be, to such Business Day. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 

This Security is subject to redemption, at the option of the Company, at any time or from time to time, in whole or in part, on any date prior to May 1,
2021 at a price equal to the greater of (i) 100% of the principal amount of this Security (or the portion hereof to be redeemed) or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on this
Security (or such portion to be redeemed) that would be due if this Security (or such portion to be redeemed) matured on May 1, 2021 but for the redemption (not including any portion of such payments of interest accrued to the Redemption Date)
discounted to the Redemption Date on a semiannual 






 
basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 12.5 basis points; plus, in each case, accrued and unpaid interest on the principal amount
being redeemed to the Redemption Date. On or after May 1, 2021, the Company may redeem this Security, at any time or from time to time, in whole or in part, by paying 100% of the principal amount of this Security (or such portion to be
redeemed) plus accrued and unpaid interest on the principal amount being redeemed to the Redemption Date. The Trustee shall have no responsibility for the calculation of such amount. 

“Treasury Rate” means, with respect to any Redemption Date the yield under the heading which represents the average for the
immediately preceding week, appearing in the most recently published statistical release designated “H.15 (519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which
establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three
months before or after the remaining life (as defined below), yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from such
yields on a straight line basis, rounding to the nearest month); or if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the
semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated by the Independent Investment Banker using 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. The Treasury Rate will be calculated by the Independent Investment Banker on the third Business Day preceding the Redemption Date. 

“Comparable Treasury Issue” means the U.S. Treasury security selected by an Independent Investment Banker as having an actual or
interpolated maturity comparable to the remaining term (“remaining life”) of this Security to be redeemed (assuming for this purpose that this Security matured on May 1, 2021) 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 this Security. 

“Comparable Treasury Price” means (1) the average of four Reference Treasury Dealer Quotations for such Redemption Date, after
excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations. 

“Independent Investment Banker” means Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC or Wells Fargo Securities,
LLC, in each case as specified by the Company, or if these firms are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing selected by the Company. 

“Reference Treasury Dealer” means each of (1) Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC and
Wells Fargo Securities, LLC 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 of America (a “Primary Treasury
Dealer”), the Company will substitute therefor another Primary Treasury Dealer and (2) any other Primary Treasury Dealer selected by the Company after consultation with the Independent Investment Banker. 

“Reference Treasury Dealer Quotations” means with respect to each Reference Treasury Dealer and any Redemption Date, the average, as
determined by the Independent Investment Banker, 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 Independent Investment Banker at 5:00 p.m.,
New York City time, on the third Business Day preceding such Redemption Date. 
 The Trustee, at the written direction of the Company, will send a notice of
redemption to each Holder of Securities to be redeemed by first-class mail (or in accordance with the procedures of The Depository Trust Company with respect to Securities registered in the name of Cede & Co.) at least 30 and not more than
60 days prior to the date fixed for redemption. Unless the Company defaults on payment of the redemption price, interest will cease to accrue on the Securities or portions thereof called for redemption on the Redemption Date. If fewer than all of
the Securities of this series are to be redeemed, the Trustee will select, not more than 60 days prior to the Redemption 






 
Date, the particular Securities of this series or portions thereof for redemption from the outstanding Securities of this series not previously called by such method as the Trustee deems fair and
appropriate. The Trustee may select for redemption Securities of this series and portions of Securities of this series in amounts of $1,000 or whole multiples of $1,000. In the case of a partial redemption of Securities registered in the name of
Cede & Co, the Securities to be redeemed will be determined in accordance with the procedures of The Depository Trust Company. 
 The
Indenture permits, with certain exceptions as therein provided, the Trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, the
Indenture with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities of all series then Outstanding under the Indenture, considered as one class; provided, however, that if there shall
be Securities of more than one series Outstanding under the Indenture and if a proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such series, then the consent only of
the Holders of a majority in aggregate principal amount of the Outstanding Securities of all series so directly affected, considered as one class, shall be required; and provided, further, that if the Securities of any series shall
have been issued in more than one Tranche and if the proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such Tranches, then the consent only of the Holders of a
majority in aggregate principal amount of the Outstanding Securities of all Tranches so directly affected, considered as one class, shall be required; and provided, further, that the Indenture permits the Trustee to enter into one or
more supplemental indentures for limited purposes without the consent of any Holders of Securities. The Indenture also contains provisions permitting the Holders of a majority in principal amount of the Securities then Outstanding, on behalf of the
Holders of all Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be
conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security. 
 As provided in the Indenture and subject to certain limitations therein set forth, this Security or any portion of the
principal amount hereof will be deemed to have been paid for all purposes of the Indenture and to be no longer Outstanding thereunder, and, at the election of the Company, the Company’s entire indebtedness in respect thereof will be satisfied
and discharged, if there has been irrevocably deposited with the Trustee or any Paying Agent (other than the Company), in trust, money in an amount which will be sufficient and/or Eligible Obligations, the principal of and interest on which when
due, without regard to any reinvestment thereof, will provide moneys which, together with moneys so deposited, will be sufficient to pay when due the principal of and interest on this Security when due. 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon
surrender of this Security for registration of transfer at the Corporate Trust Office of The Bank of New York Mellon Trust Company, National Association in New York, New York, or such other office or agency as may be designated by the Company from
time to time, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities of this series of authorized denominations and of like tenor and aggregate principal amount, will be issued to the designated transferee or transferees. 

The Securities of this series are issuable only as registered Securities, without coupons, and in denominations of $1,000 and integral multiples of $1,000 in
excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of the same series and Tranche, of any authorized
