	No.        	  	$        

 LACLEDE GAS COMPANY, a corporation of the State of Missouri (hereinafter called “the Company”),
for value received hereby promises to pay to                      or registered assigns, at the office or agency of the Company in the Borough of
Manhattan, 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 [—] day of [—], 20[—] (or upon earlier redemption), by check or draft (or as otherwise provided herein) in
such coin or currency of the United States of America as at the time of payment shall be legal tender for public and private debts, and to pay to the registered owner hereof by check or draft (or as otherwise provided herein) interest thereon from
and including [—], 20[—] or from the fifteenth day of [—] or
[—] 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 [—]% per annum, in like coin or currency at either of said offices or agencies at the option of the registered
owner hereof, on [—] and [—] 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 Trustee is closed for business. The 

  
 11 









 
interest so payable on any [—] or [—] will, subject to certain exceptions provided in the
Mortgage hereinafter mentioned, be paid to the person in whose name this bond is registered at the close of business on the record date, which shall be [—] or
[—], as the case may be, next preceding such interest payment date (whether or not a Business Day). Notwithstanding the foregoing, so long as the holder is The Depository Trust Company
(“DTC”) or a nominee thereof, such payments of principal and interest will be made in accordance with the Blanket Issuer Letter of Representations dated April 20, 2004 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, [—]% Series due [—], 20[—] (hereinafter referred to as the
“[—] Series”), all bonds of all series issued and to be issued under and equally secured (except in so far as any sinking or other fund established in accordance with the provisions of the
Mortgage hereinafter mentioned may afford additional security for the bonds of any particular series) by a Mortgage and Deed of Trust (hereinafter referred to as the “Original Indenture”) dated as of February 1, 1945, executed by the
Company to Mississippi Valley Trust Company, which was succeeded through consolidation by Mercantile Trust Company, which was succeeded by Mercantile Trust Company National Association, which was succeeded by Mercantile Bank National Association,
which was succeeded by Mercantile Bank of St. Louis National Association, which was succeeded by State Street Bank and Trust Company of Missouri, N.A., which in turn was succeeded by UMB Bank & Trust, n.a., as Trustee, and indentures
supplemental thereto, including the [—] Supplemental Indenture thereto dated as of [—], 20[—]
(hereinafter referred to as the “[—] Supplemental Indenture”), said Mortgage and Deed of Trust as supplemented being herein called the “Mortgage,” to which reference is made for a
description of the property mortgaged and pledged, the nature and extent of the security, 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 [—] 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 the owner hereof of a lien upon
such property without the consent of the owner hereof, except that the owners of not less than seventy-five 

  
 12 









 
percent (75%) in principal amount of the bonds at any time outstanding under the Mortgage (including a like percent of the principal amount of the bonds of the [—] Series, if any interest payment on bonds of the [—] Series is to be affected) may consent on behalf of the owners of all bonds at any time outstanding
to the postponement of any interest payment for a period not exceeding three years from its due date. 
 Each initial and future
holder of this bond and every other bond of the of the [—] Series, by its acquisition of an interest herein or therein, irrevocably (1) consents to the amendments of the Mortgage set forth in
Section 5.1 of Article V of the [—] Supplemental Indenture without any other or further action by any holder of such bonds, including without limitation to the amendment to the Mortgage to
change the vote required for modifications and alterations of 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
referenced in the last sentence of the preceding paragraph from 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 to the affirmative
vote of the owners of at least a majority in principal amount of the bonds affected by such modification or alteration; and (2) designates the Trustee, and its successors, as its proxy with irrevocable instructions to vote and deliver written
consents on its behalf in favor of such amendments at any bondholder meeting, in any consent solicitation in lieu of any bondholder meeting or otherwise. 
 The bonds of the [—] Series are redeemable, upon the notice referred to below, and otherwise subject to the provisions of the Mortgage:
[(i)] pursuant to paragraph (B) of Section 13.06 of the Original Indenture (having reference to the taking of all the mortgaged property by eminent domain and certain comparable contingencies) at 100% of the principal amount thereof,
together with accrued interest thereon to the date fixed for redemption; [or (ii) pursuant to Section 3.2 of the [—] Supplemental Indenture, [insert optional redemption provisions, if
any]]. Except as set forth above, the bonds of the 20[—] Series are not redeemable prior to [—],

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

this paragraph in such calendar year, shall not exceed the greater of (a) Twenty Million Dollars ($20,000,000) or (b) three per centum (3%) of the aggregate principal amount of bonds then outstanding, upon the application of the

signers, the release thereof will not impair the security under this Indenture in contravention of the provisions hereof. 
 On
or before December 31st of each calendar year, the Company shall (1) deposit with the Trustee an amount in cash equal to seventy-five per centum (75%) of the aggregate cost of the properties constituting funded property so released
during such year (or, if the fair value to the Company of any particular property at the time the same became funded property was certified to be an amount less than the cost thereof, then such fair value, as


  
 29 









 
so certified, in lieu of cost) or (2) identify property additions not constituting funded property to take the place of the funded property so released, which property additions shall

shall be required to be made hereunder to the extent that cash or other consideration shall, as indicated in a Treasurer’s Certificate delivered to the Trustee, have been deposited with the trustee or holder of other lien prior to the lien of
this Indenture in accordance with the provisions thereof; and provided, further, that the amount of cash so required to be deposited may be reduced, at the election of the Company, by the items specified in clause (5) in the first paragraph of

Indenture and conclusive in favor of the Trustee and the Company.” 

  
 32 









 (q) To amend Section 21.04 of the Mortgage to read substantially as follows:

 “SECTION 21.04. Any power, privilege or right expressly or impliedly reserved to or in any way conferred
upon the Company by any provision of this Indenture, whether such power, privilege or right is in any way restricted or is unrestricted, may be in whole or in part waived or surrendered or subjected to any restriction if at the time unrestricted or
to additional restriction if already restricted. Anything in this Indenture to the contrary notwithstanding, the Company and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental hereto, in form
satisfactory to the Trustee, for any of the following purposes: (i) to enter into any further covenants, limitations or restrictions for the benefit of any one or more series of bonds issued hereunder and provide that a breach thereof shall be
equivalent to a default under this Indenture; (ii) to cure any ambiguity or correct or supplement any defective or inconsistent provisions contained herein or in any supplemental indenture; (iii) to correct or amplify the description of
any property at any time subject to the lien of this Indenture, or better assure, convey and confirm unto the Trustee any property subject or required to be subjected to the lien of this Indenture, or subject to the lien of this Indenture additional
property; or (iv) to change or eliminate any provision of this Indenture or to add any new provision to this Indenture provided that no such change, elimination or addition shall adversely affect the interests of the holders of bonds of any
series. The Trustee is hereby authorized to join with the Company in the execution of any such instrument or instruments. Such instrument, executed and acknowledged as aforesaid, shall be delivered to the Trustee and thereupon if such instrument
shall have been signed by the Trustee any modification of the provisions of these presents therein set forth, authorized by this Section, shall be binding upon the parties hereto, their successors and assigns, and the holders of the bonds and
coupons hereby secured. Anything to the contrary notwithstanding, this Section shall not be construed to permit any act, waiver, surrender or restriction adversely affecting any bonds then outstanding hereunder. 

Without limiting the generality of the foregoing, if the Trust Indenture Act of 1939, as in effect at any time and from
time to time, 
 (i) shall require one or more changes to any provisions hereof or the inclusion herein of any
additional provisions, or shall by operation of law be deemed to effect such changes or incorporate such provisions by reference or otherwise, this Indenture shall be deemed to have been amended so as to conform to the Trust Indenture Act as then in
effect, and the Company and the Trustee may, without the consent of any holders of bonds, enter into an indenture supplemental hereto to evidence such amendment hereof; or 

(ii) shall permit one or more changes to, or the elimination of, any provisions hereof which shall theretofore have been
required by the Trust Indenture Act of 1939 to be contained herein or are contained herein to reflect any provisions of the Trust Indenture Act of 1939, this Indenture shall be deemed to have been amended to effect such changes or elimination, and
the Company and the Trustee may, without the consent of any holders of bonds, enter into an indenture supplemental hereto to evidence such amendment hereof.”

(a) consents to the modification and alterations to the Mortgage set forth in this Article V of this [—] Supplemental Indenture without any other or further action by any such holder of such
bonds, (b) designates the Company, 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 bondholder meeting, in lieu of any bondholder
meeting, in any consent solicitation or otherwise and (c) waives all conditions precedent to such modifications and alterations, in Article XX of the Mortgage or otherwise (including but not limited to any requirements as to the holding of a
