The New Bonds shall mature on March 15, 2029, and shall bear interest at the rate per annum set forth in the form of the New Bond
contained in Section 3 of this Article I, payable semi-annually in arrears on the 15th day of March and the 15th day of September in each year (each, an “Interest Payment Date”), commencing on September 15, 2019, and at

Company. 
 Notwithstanding the provisions of Section 6 of Article II of the Original Indenture, the New Bonds shall be dated the
date of authentication and shall bear interest from the Interest Payment Date to which interest on the New Bonds has been paid next preceding the date thereof, unless such date is an Interest Payment Date to which interest has been paid, in which
case they shall bear interest from the date thereof, or unless the date thereof is prior to September 15, 2019, in which case they shall bear interest from March 6, 2019; provided, however, that, subject to the provisions of this
Section with respect to failure by the Company to pay any interest on an Interest Payment Date, the holder of any New Bond dated after a record date (as hereinafter defined) for the payment of interest and prior to the date of payment of such
interest shall not be entitled to payment of such interest and shall have no claim against the Company with respect thereto. 
 The person
in whose name any New Bond is registered at the close of business on any record date with respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date notwithstanding the cancellation of such
Bond upon any transfer or exchange thereof subsequent to the record date and prior to such Interest Payment Date, except if and to the extent the Company shall default in the payment of the interest due on such Interest Payment Date, in which case
such defaulted interest shall be paid to the person in whose name such Bond is registered on the date of payment of such defaulted interest or on a subsequent record date for such payment if one shall have been established as hereinafter provided. A
subsequent record date may be established by the Company by notice mailed to the holders of the New Bonds not less than ten days preceding such record date, which record date shall be not more than thirty days prior to the subsequent Interest
Payment Date. The term “record date” as used in this Section with respect to any regular interest payment date shall mean the March 1 or September 1, as the case may be, next preceding such Interest Payment Date, or, if such
March 1 or September 1 shall be a legal holiday in the State of New York or in the State of Missouri or a day on which banking institutions in the Borough of Manhattan, The City of New York, or the City of St. Louis, Missouri, are
authorized by law to close, the next preceding day which shall not be a legal holiday or a day on which such institutions are so authorized to close.

which interest has not been paid, unless the date hereof is a March 15 or September 15 to which interest has been paid, in which case from the date hereof, or unless the date hereof is prior to the first payment of interest, in which case
from the Original Issue Date set forth above. The interest so payable will be paid to the person in whose name this Bond, or the Bond in exchange or substitution for which this Bond shall have been issued, shall have been registered at the close of
business on the March 1 or September 1, as the case may be (each, a “Record Date”), next preceding the date of payment, subject to certain exceptions set forth in the Amended Indenture. The principal of, premium, if any, and
interest on, this Bond are payable, in immediately

available funds, at the office of the Trustee hereinafter referred to; provided, however, that at the option of the Company, interest on this Bond may be paid by check mailed to the registered
holder of this Bond at such holder’s address as it shall appear on the books of the Company to be kept for that purpose or by a wire transfer to an account designated by the registered holder of this Bond entitled thereto. 

This Bond shall not be entitled to any benefit under the Amended Indenture or any indenture supplemental thereto, or become valid or
obligatory for any purpose, until The Bank of New York Mellon, the Trustee under the Amended Indenture, or a successor trustee thereto under the Amended Indenture, or an agent therefor, shall have signed the form of certificate endorsed hereon. 

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.

 [FORM OF REVERSE OF NEW BOND] 

This Bond is one of a duly authorized issue of Bonds of the Company (herein called the “Bonds”), in unlimited aggregate principal
amount, of the series hereinafter specified, all issued and to be issued under and equally secured by the Indenture of Mortgage and Deed of Trust, dated June 15, 1937, executed by the Company to The Bank of New York Mellon, formerly The Bank of
New York (successor trustee to Bank of America, National Association, formerly Boatmen’s Trust Company), as trustee (herein called the “Trustee”), as amended by indentures supplemental thereto dated May 1, 1941, April 1,
1971, February 1, 1974, July 7, 1980, February 1, 2000, August 15, 2002 and May 15, 2012, between the Company and the Trustee (said mortgage and deed of trust, as so amended, being herein called the “Amended
Indenture”), to which Amended Indenture and all indentures supplemental thereto reference is hereby made for a description of the properties mortgaged and pledged, the nature and extent of the security, the rights of the bearers or registered
owners of the Bonds and of the Trustee in respect thereto, and the terms and conditions upon which the Bonds are, and are to be, secured. To the extent permitted by, and as provided in, the Amended Indenture, modifications or alterations of the
Amended Indenture, or of any indenture supplemental thereto, and of the rights and obligations of the Company and of the holders of the Bonds may be made with the consent of the Company by an affirmative vote of not less than 60% in amount of the
Bonds entitled to vote then outstanding, at a meeting of Bondholders called and held as provided in the Amended Indenture, and by an affirmative vote of not less than 60% in amount of the Bonds of any series entitled to vote then outstanding and
affected by such modification or alteration, in case one or more but less than all of the series of Bonds then outstanding under the Amended Indenture are so affected. Additionally, the Company may amend the Amended Indenture, as supplemented, by an
appropriate written consent of not less than 60% in aggregate principal amount of the Bonds outstanding (and, if the rights of one or more, but less than all, series of Bonds then outstanding are to be affected by action taken pursuant to such
consent, then also by consent of the holders of at least 60% in principal amount of each series of Bonds so to be affected and outstanding hereunder) without a meeting of such Bondholders. No such modification or alteration shall be made which will
affect the terms of payment of the principal of, or interest or premium on, this Bond, which are unconditional. The Bonds may be issued in series, for various principal sums, may mature at different times, may bear interest at different rates and
may otherwise vary as in the Amended Indenture provided. This Bond is one of a series designated as the “3.50% First Mortgage Bonds due 2029” (herein called the “Bonds of this Series”) of the Company, issued under and secured by
the Amended Indenture and described in the indenture (hereinafter called the “New Supplemental Indenture”) dated March 1, 2019, between the Company and the Trustee, supplemental to the Amended Indenture. 

The Bonds of this Series are not entitled to the benefit of any improvement, maintenance or analogous fund. 

All or a portion of the Bonds of this Series may be redeemed at the option of the Company at any time or from time to time. The
redemption price for the Bonds of this Series to be redeemed on any redemption date prior to December 15, 2028 (three months prior to the Maturity Date) (the “Par Call Date”) will be equal to the greater of the following amounts:
(a) 100% of the principal amount of the Bonds of this Series being redeemed on that redemption date; or (b) the sum of the present values of the remaining scheduled payments of principal and interest on the Bonds of this Series being
redeemed on that redemption date that would be payable if such Bonds matured on the Par Call Date (not including any portion of any 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 Adjusted Treasury Rate (as defined below), plus 15 basis points, as determined by the Reference
Treasury Dealer (as defined below), plus, in each case, accrued and unpaid interest thereon to the redemption date. The redemption price for the Bonds of this Series to be redeemed on any redemption date on or after the Par Call Date will be equal
to 100% of the principal amount of the Bonds of this Series being redeemed on that redemption date plus accrued and unpaid interest thereon to the redemption date. Notwithstanding the foregoing, installments of interest on Bonds of this
Series that are due and payable on Interest Payment Dates falling on or prior to a redemption date will be payable on the Interest Payment Date to the Holder of this Bond as of the close of business on the relevant Record Date. 

With respect to a redemption occurring prior to the Par Call Date, the Company shall give the Trustee written notice of the redemption price
promptly after the calculation thereof and the Trustee shall not be responsible for such calculation. 

  
 10 

 The Company shall send notice of any redemption at least 10 days but not more than
60 days before the redemption date to each Holder of the Bonds of this Series to be redeemed, and, if less than all Bonds of this Series are to be redeemed, the particular Bonds of this Series to be redeemed will be selected by the Trustee
by lot; provided that as long as the Bonds of this Series are represented by global certificates, beneficial interests in such global certificates will be selected for redemption by The Depository Trust Company in accordance with its standard
procedures therefor. Unless the Company defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Bonds of this Series or portions thereof called for redemption. 

Any notice of redemption at the Company’s option may state that such redemption will be conditional upon receipt by the Trustee, on or
prior to the redemption date, of money sufficient to pay the principal of and premium, if any, and interest on, the Bonds of this Series or portions thereof called for redemption, and that if such money has not been so received, such notice will be
of no force and effect and the Company will not be required to redeem such Bonds or portions thereof. 
 “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 the United States
Treasury security selected by the Reference Treasury Dealer as having a maturity comparable to the remaining term of the Bonds of this Series to be redeemed (assuming, for this purpose, that the 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 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, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (B) if the Company obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such
quotations, or (C) if only one Reference Treasury Dealer Quotation is received, such quotation. 
 “REFERENCE TREASURY
DEALER” means each of (A) Barclays Capital Inc., RBC Capital Markets, LLC, TD Securities (USA) LLC and a Primary Treasury Dealer (as defined below) selected by MUFG Securities Americas Inc., or, in each case, an affiliate thereof, which
are primary U.S. Government securities dealers in the United States (each, a “Primary Treasury Dealer”), and their respective successors; provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the
Company shall substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Company. 

“REFERENCE TREASURY DEALER QUOTATIONS” 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. 
 In case an event of default, as defined in the Amended
Indenture, shall occur, the principal of all the Bonds at any such time outstanding under the Amended Indenture may be declared or may become due and payable, upon the conditions and in the manner and with the effect provided in the Amended
Indenture. The Amended Indenture provides that such declaration may in certain events be waived by the holders of a majority in principal amount of the Bonds outstanding. 

This Bond is exchangeable by the registered owner hereof, in person or by duly authorized attorney, on the books of the Company to be kept for
that purpose at the office of the Company in the City of St. Louis, Missouri, upon surrender and cancellation of this Bond and on presentation of a duly executed written instrument of transfer, and thereupon a new Bond or Bonds of the same
series, of the same aggregate principal amount and in authorized denominations will be issued to the transferee or transferees in exchange herefor, without payment of any charge other than stamp taxes and other governmental charges incident thereto;
and this Bond with or without others of like 

  
 11 

 
series, may in like manner be exchanged for one or more new Bonds of the same series of other authorized denominations but of the same aggregate principal amount; all subject to the terms and
conditions set forth in the Amended Indenture. 
 Each initial and future Holder of this Bond, by its acquisition of an interest in this
Bond, irrevocably (a) consents to the amendments set forth in Article III of the Supplemental Indenture dated as of May 15, 2012, supplemental to the Amended Indenture, without any other or further action by any Holder of this Bond, and
(b) designates the Trustee, and its successors, as its proxy with irrevocable instructions to vote and deliver written consents on behalf of such Holder in favor of such amendments at any meeting of Holders, in lieu of any meeting of Holders,
in response to any consent solicitation or otherwise. 
 No recourse shall be had for the payment of the principal of, premium, if any, or
the interest on, this Bond, or for any claim based hereon or on the Amended Indenture or any indenture supplemental thereto, against any incorporator, or against any stockholder, director or officer, past, present or future, of the Company, or of
any predecessor or successor corporation, either directly or through the Company or any such predecessor or successor corporation, whether for amounts unpaid on stock subscriptions or by virtue of any constitution, statute or rule of law, or by
the enforcement of any assessment or penalty or otherwise, all such liability, whether at common law, in equity, by any constitution, statute or otherwise, of incorporators, stockholders, directors or officers being released by every owner hereof by
the acceptance of this Bond and as part of the consideration for the issue hereof, and being likewise released by the terms of the Amended Indenture.
