The City of New York, or at the option of the registered owner hereof at the office or agency of the Company in the City of St. Louis, State of Missouri, _____________________ Dollars on the first day of June, 2051 (or upon earlier redemption), by

as otherwise provided herein) interest thereon from and including May 20, 2021 or from the first day of June or December next preceding the date of this bond to which date interest has been paid or duly provided for (or, if this bond is dated
any date after the record date for any interest payment date and on or before such interest payment date, then from such interest payment date), at the rate of 3.300% per annum, in like coin or currency at either of said offices or agencies at the
option of the registered owner hereof, on June 1 and December 1 in each year, until the Company’s obligation with respect to the payment of such principal shall have been discharged. If any interest payment date or any date of
maturity or redemption of principal of this bond falls on a day that is not a Business Day (as defined below), principal and/or interest payable on such date will be paid on the succeeding Business Day with the same force and effect as if it were
paid on the date such payment was due, and no interest will accrue on the amount so payable for the period from and after such date to such succeeding Business Day. “Business Day” means any day other than a Saturday, Sunday, or other day
on which commercial banks are authorized or required by law, regulation, or executive order to close in the Borough of Manhattan, The City of New York, or in the City of St. Louis, State of Missouri or on which the corporate trust office of the

 15 













 
hereinafter mentioned, be paid to the person in whose name this bond is registered at the close of business on the record date for the applicable interest payment date, which will be the close of
business on the fifteenth (15th) calendar day next preceding such interest payment date (whether or not a Business Day). Notwithstanding the foregoing, so long as the holder of this bond is The Depository Trust Company (“DTC”) or a nominee
thereof, such record date shall be the close of business on the Business Day next preceding such interest payment date and otherwise such payments of principal and interest will be made in accordance with the Blanket Issuer Letter of Representations
dated May 10, 2021 between DTC and the Company (or such successor arrangement thereto). If a registered owner of an aggregate principal amount in excess of $100,000 of the bonds so requests, payments of principal and interest to that registered
owner shall be made by electronic transfer to an account at a commercial bank or savings institution located in the continental United States designated in writing by such registered owner. Any such request must be made in writing to the Company and
UMB Bank & Trust, N.A. (hereinafter sometimes referred to as the “Trustee”) at least 10 days in advance of such payment and must specify the name and address of the receiving bank, its ABA routing number, and the account name and
number to receive the electronic transfer. 
 This bond is one of an issue of bonds of the Company, issuable in series, and
is one of a series known as its First Mortgage Bonds, 3.300% Series due June 1, 2051 (hereinafter referred to as the “2051 Series”), all bonds of all series issued and to be issued under and equally secured (except in so far as any

the rights of the owners of the bonds in respect thereof, the duties and immunities of the Trustee, and the terms and conditions upon which the bonds are secured. Subject to the provisions of the next paragraph, with the consent of the Company and
to the extent permitted by and as provided in the Mortgage, the rights and obligations of the Company and/or of the owners of the bonds and/or coupons and/or the terms and provisions of the Mortgage and/or of any instruments supplemental thereto may
be modified or altered by the affirmative vote of the owners of at least sixty-six and two-thirds percent (66 2/3%) in principal amount of the bonds affected by such
modification or alteration (including the bonds of the 2051 Series, if so affected), then outstanding under the Mortgage (excluding bonds disqualified from voting by reason of the Company’s interest therein as provided in the Mortgage);
provided that no such modification or alteration shall permit the extension of the maturity of the principal of this bond or the reduction in the rate of interest hereon or any other modification in the terms of payment of such principal or
interest, or the creation of a lien on the mortgaged and pledged property ranking prior to or on a parity with the lien of the Mortgage or the deprivation of

Thirty-Fifth Supplemental Indenture, at a redemption price equal to (A) if redeemed at any time prior to December 1, 2050 (the “Par Call Date”), the greater of (y) 100% of the principal amount thereof to be redeemed on the
redemption date and (z) the sum of the present values of the remaining scheduled payments of principal and interest of the bonds of 2051 Series to be redeemed that would be due if the bonds of the 2051 Series matured on the Par Call Date (not
including any portion of any payments of interest accrued to the redemption date), in each case discounted from their respective scheduled payment dates to such redemption date on a semiannual basis (assuming a
360-day year consisting of 30-day months) at the Adjusted Treasury Rate (as defined in the Thirty-Fifth Supplemental Indenture) plus 15 basis points, as determined by
the Quotation Agent (as defined in the Thirty-Fifth Supplemental Indenture), plus, in each case, accrued and unpaid interest thereon to the redemption date, and (B) if redeemed at any time on or after the Par Call Date, 100% of the principal
amount thereof to be redeemed on the redemption date, plus accrued and unpaid interest thereon to the redemption date. Notwithstanding the foregoing, (1) interest payable with respect to an interest payment date on any bond of the 2051 Series
to be redeemed that falls on or before the redemption date therefor shall be made to the holder thereof on the record date related to such interest payment date, and (2) if any redemption date falls on a day that is not a Business Day,
principal and/or interest and premium, if any, payable on such date will be paid on the next succeeding Business Day with the same force and effect as if it were paid on the redemption date and no interest will accrue on the

amount so payable for the period from and after the redemption date to the next succeeding Business Day. Except as set forth above, the bonds of the 2051 Series are not redeemable prior to
June 1, 2051. 
 The notice of redemption of bonds of the 2051 Series shall be given by mailing a copy thereof to each
registered owner, directed to his registered address not less than twenty (20) nor more than sixty (60) days prior to the date fixed for redemption, all as provided in, and subject to the applicable provisions of, the Mortgage. 

The principal hereof and the interest accrued hereon may be declared or may become due on the conditions, in the manner, and
at the time set forth in the Mortgage, upon the occurrence of a completed default as in the Mortgage provided. 
 At the
option of the registered owner, any bonds of the 2051 Series, upon surrender thereof at the office or agency of the Company in the Borough of Manhattan, The City of New York, or in the City of St. Louis, State of Missouri, together with a written
instrument of transfer in form approved by the Company duly executed by the registered owner or his duly authorized attorney, shall, subject to the provisions of Section 2.05 of the Original Indenture, be exchangeable for a like aggregate
amount of fully registered bonds of the same series of other authorized denominations.

cancellation of this bond and upon presentation of a written instrument of transfer, duly executed, with signature guaranteed by a signature guarantor that is a participant in a nationally recognized signature guaranty program, and upon payment, if
the Company shall require it, of the transfer charges prescribed in the Mortgage, and thereupon, a new fully registered bond of the same series for a like principal amount will be issued to the transferee in exchange herefor as provided in the
Mortgage. The Company and the Trustee may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment and for all other purposes. 

No recourse shall be had for the payment of the principal of or of interest on this bond against any incorporator or any past,
present or future subscriber to the capital stock, stockholder, officer or director of the Company or of any predecessor or successor corporation, as such, either directly or through the Company or any predecessor or successor corporation, under any
rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers, stockholders, officers and directors, as such, being released by the owner hereof by the acceptance of this
bond and being likewise waived and released by the terms of the Mortgage. 
 This bond shall not become obligatory until UMB

bonds of the 2051 Series will contain the same terms (including the maturity date and interest rate), except for the public offering price, the issue date and, if applicable, the first interest
payment date, as the other bonds of the 2051 Series. Any such additional bonds of the 2051 Series, together with the bonds of the 2051 Series initially authenticated, shall constitute a single series for purposes of the Mortgage. 

SECTION 2.2 Date of Bonds. All bonds of the 2051 Series shall be dated as provided in Section 2.03 of the Original

SECTION 2.4 Exchange of Bonds. At the option of the registered owner, any bonds of the 2051 Series, upon surrender thereof at
the office or agency of the Company in the Borough of Manhattan, The City of New York, or in the City of St. Louis, State of Missouri, together with a written instrument of transfer in form approved by the Company duly executed by the registered

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.
The record date for the applicable interest payment date shall be the fifteenth (15th) calendar day (whether or not a Business Day) next preceding such interest payment date. Notwithstanding the foregoing, so long as the holder of the bonds of the

whole or in part, at 100% of the principal amount thereof, together with accrued interest thereon to the date fixed for redemption at any time before maturity pursuant to the provisions of paragraph (B) of Section 13.06 of the Original
Indenture. 
 SECTION 3.2 Additional Circumstances in Which Redeemable. Bonds of the 2051 Series shall also be redeemable,
at the option of the Company, in whole at any time or in part from time to time, (i) at any time prior to the Par Call Date (as defined below), at a redemption price equal to the greater of (x) 100% of the principal amount of the bonds of the
2051 Series to be redeemed on the redemption date and (y) the sum of the present values of the remaining scheduled payments of principal and interest of the bonds of the 2051 Series to be redeemed that would be due if the bonds of the 2051
Series matured on the Par Call Date (not including any portion of any payments of interest accrued to the redemption date), in each case discounted from their respective scheduled payment dates to such redemption date on a semiannual basis (assuming
a 360-day year consisting of 30-day months) at the Adjusted Treasury Rate (as defined below) plus 15 basis points, as determined by the Quotation Agent (as defined
below), plus, in each case, accrued and unpaid interest thereon to the redemption date, and (ii) at any time on or after the Par Call Date, at a redemption price equal to 100% of the principal amount of the bonds of the 2051 Series to be
redeemed on the redemption date plus accrued and unpaid interest thereon to the redemption date. 
 Notwithstanding the
foregoing, (1) interest payable with respect to an interest payment date on any bond of the 2051 Series to be redeemed that falls on or before the redemption date therefor shall be made to the holder thereof on the record date related to such
interest payment date, and (2) if any redemption date falls on a day that is not a Business Day, principal and/or interest and 

  
 28 













 
premium, if any, payable on such date will be paid on the next succeeding Business Day with the same force and effect as if it were paid on the redemption date and no interest will accrue on the
amount so payable for the period from and after the redemption date to the next succeeding Business Day. 
 For purposes of
this Section 3.2: 
 “Adjusted Treasury Rate” means, with respect to any optional redemption date, the
rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated on the third Business Day preceding such redemption date 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 Quotation Agent as having a maturity comparable to the remaining term of the bonds of the 2051 Series (assuming, for this purpose, that the bonds of the 2051 Series mature 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 such comparable maturity. 

“Comparable Treasury Price” means, with respect to any optional redemption date, (i) the average of the
Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Quotation Agent obtains fewer than three such Reference Treasury Dealer Quotations,

“ Par Call Date” means December 1, 2050. 

“Quotation Agent” means one of the Reference Treasury Dealers appointed by the Company.

the Company. 
 “Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer
and any optional redemption date, the average, as determined by the Quotation Agent, 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 Quotation

PARTICULAR COVENANTS OF THE COMPANY 

SECTION 4.1 Restrictions as to Dividends. So long as any of the bonds of the 2051 Series are outstanding, the Company will not
(a) declare any dividends (other than dividends in common stock) on any common stock, or order the making of any distribution on any shares of common stock or to owners of common stock or (b) purchase, redeem or otherwise acquire or retire
for value any shares of common stock, if the aggregate net amount of such declarations, distributions so ordered, purchases, redemptions, acquisitions and retirements after September 30, 1953, would exceed the sum of (y) the Net Income
Available for Common Stock for the period beginning October 1, 1953, and ending with the last day of the calendar quarter immediately preceding the calendar quarter in which such dividend is declared, distribution ordered, or purchase,
redemption, acquisition or retirement made, plus (z) Eight Million Dollars ($8,000,000). 
 The aggregate net amount of
the declarations, distributions ordered, purchases, redemptions, acquisitions and retirements referred to in the first paragraph of this Section 8.1 shall be determined by deducting from the aggregate amount thereof the total amount of cash
payments received by the Company after September 30, 1953, for any shares of common stock sold by the Company after September 30, 1953. 

Net Income Available for Common Stock, for the purpose of this Section 4.1, for any period, means (1) the net income
of the Company for such period computed according to the applicable system of accounts prescribed by the Public Service Commission of Missouri and any applicable orders of said Commission and (to the extent not prescribed by such system of accounts

to assets or dividends. 
 For the purposes of the last preceding paragraph of this Section 4.1, the term “Public
Service Commission of Missouri” shall also apply, and be deemed to refer, to any regulatory body which may (A) succeed said Commission with respect to jurisdiction over the accounting of the Company, or (B) supersede said Commission
with respect to such jurisdiction, or (C) have such jurisdiction over phases of the Company’s business or parts of its property over which said Commission shall not have jurisdiction.

 SECTION 4.2 Earnings Requirements for Additional Bonds. So long as any bonds
of the 2051 Series are outstanding, the Company shall not be entitled to have authenticated and delivered any bonds pursuant to Article VI, Article VII or Article VIII of the Original Indenture, except bonds which may be authenticated and delivered
under Article VII of the Original Indenture, without the receipt by the Trustee of a net earnings certificate showing the net earnings to be as required by Section 6.05 of the Original Indenture, unless (in addition to all other requirements
for the authentication and delivery of such bonds): 
 (a) net earnings of the Company after provision for depreciation,
depletion and amortization of property, for any 12 consecutive calendar months within the 15 calendar months immediately preceding the date on which such additional bonds are to be issued, shall have been not less than 2 1/4 times the amount of the
total annual interest charges upon the funded debt of the Company to be outstanding immediately after the issue of such additional bonds; and 

(b) the Trustee shall have received a certificate made, signed and verified by the same persons (including an independent
public accountant where required) as would be required if such certificate were a net earnings certificate under the Original Indenture, showing the net earnings of the Company to be as required by the foregoing clause (a) of this
Section 4.2. Such certificate shall show the net earnings and total annual interest charges referred to in said clause (a). 

For the purposes of this Section 4.2, “funded debt” shall mean all indebtedness created or assumed by the
Company maturing one year or more after the date of the creation or assumption thereof. 
 For the purposes of this
Section 4.2, net earnings of the Company after provision for depreciation, depletion and amortization of property shall mean the total operating revenue and other income (net) of the Company less operating expenses (including provision for
depreciation, depletion and amortization of property) and less taxes (excluding income and excess profits taxes or other taxes which are imposed on or measured by income). In the determination of net earnings of the Company the following additional
requirements shall be applicable: 
 (i) No profits or losses from the sale or abandonment of capital assets
or change in value of securities or other investments shall be taken into account in making such computations; 

(ii) In case the Company shall have sold any property for a consideration in excess of $5,000,000, within or
after the particular period for which the calculation is made, then, in computing the net earnings of the Company so available, the net earnings or net losses of such property for the whole of such period shall be excluded to the extent practicable
on the basis of actual earnings and expenses of such property or on the basis of such estimates of the earnings and expenses of such property as the signers of a Treasurer’s certificate filed with the Trustee shall deem proper; 

(iii) In case the Company shall, within or after the particular period for which the calculation is made, have
acquired (by purchase, merger, consolidation or otherwise) any property which within six months prior to the date of acquisition thereof by the 

  
 31 













 
Company has been used or operated by a person or persons other than the Company in a business similar to that in which it has been or is to be used or operated by the Company, then in computing
the net earnings of the Company so available for such purposes there shall be included, to the extent that they may not have been otherwise included, the net earnings or net losses of the property so acquired for the whole of such period to the
extent practicable on the basis of actual earnings and expenses of such property or on the basis of such estimates of the earnings and expenses of such property as the signers of a Treasurer’s certificate filed with the Trustee shall deem
proper. The net earnings or net losses of such property for the period preceding such acquisition shall in such case be ascertained and computed as provided in this clause (iii) as if such acquired property had been owned by the Company during
the whole of such period; and 
 (iv) The “net earnings of property” referred to in clauses
(ii) and (iii) of this Section 4.2 shall mean the net earnings of such property computed in the manner provided in this definition for the computation of net earnings of the Company available for the pertinent purposes. 

All accounting determinations required by this Section 4.2 shall (except to the extent, if any, to which the preceding
provisions of this Section 4.2 may conflict with this provision) be made according to the applicable system of accounts prescribed by the Public Service Commission of Missouri and any applicable orders of said Commission and (to the extent not
prescribed by such system of accounts or orders) according to generally accepted accounting principles. 
 For the purposes
of this Section 4.2, the term “Public Service Commission of Missouri” shall be applicable as provided in Section 4.1 of this Article IV. 

SECTION 4.3 Postponement of Interest. So long as any bonds of the 2051 Series are outstanding, in order that any interest
payment on the bonds of any of the 2051 Series may be postponed pursuant to clause (2) of Section 20.07 of the Original Indenture, there shall be required, in addition to all other prerequisites to such postponement provided in the
Original Indenture, the consent of the owners of not less than seventy-five percent (75%) in principal amount of bonds of the 2051 Series at the time outstanding, such consent to be given at the same time as and in the same manner as the consent of
the owners of other bonds required by said clause (2) of Section 20.07 of the Original Indenture.
