 WHEREAS, the
Company has requested that the Trustee execute and deliver this First Supplemental Indenture; and 
 WHEREAS, all things necessary to make

 NOW THEREFORE, in consideration of the premises and the purchase and acceptance of the Notes by the Holders thereof, and for the
purpose of setting forth, as provided in the Indenture, the forms and terms of the Notes, it is mutually covenanted and agreed, for the equal and proportionate benefit of all Holders of the Notes, as follows: 

ARTICLE ONE 

DEFINITIONS 

Section 1.01. Definition of Terms. Unless the context otherwise requires: 

(a) each term defined in the Indenture has the same meaning when used in this First Supplemental Indenture; 

(b) each term defined anywhere in this First Supplemental Indenture has the same meaning throughout; 

(c) the singular includes the plural and vice versa; and 

(d) headings are for convenience of reference only and do not affect interpretation. 







 ARTICLE TWO 

GENERAL TERMS AND CONDITIONS OF THE FLOATING RATE NOTES 

Section 2.01. Designation and Principal and Amount. There is hereby authorized and established a series of Securities under the
Indenture, designated as the “Floating Rate Senior Notes due 2017”, which is not limited in aggregate principal amount. The aggregate principal amount of the Floating Rate Notes to be issued on the date hereof is $250,000,000. Floating
Rate Notes in the aggregate principal amount of $250,000,000 may, upon execution of this First Supplemental Indenture, be executed by the Company and delivered to the Trustee for authentication and the Trustee shall, upon receipt of a Company Order,
authenticate and deliver said Floating Rate Notes as provided in said Company Order. 
 Section 2.02. Maturity. The Stated
Maturity of principal of the Floating Rate Notes is August 15, 2017. 
 Section 2.03. Further Issues. The Company may from
time to time, without the consent of the Holders of the Floating Rate Notes, issue additional Floating Rate Notes. Any such additional Floating Rate Notes will have the same ranking, interest rate, maturity date and other terms as the Floating Rate
Notes herein provided for (except for the original issue date, the public offering price and, if applicable, the initial interest payment date). Any such additional Floating Rate Notes, together with the Floating Rate Notes herein provided for, will
constitute a single series of Securities under the Indenture. No additional Floating Rate Notes may be issued if an Event of Default has occurred and is continuing with respect to the Floating Rate Notes. The Company will not issue any additional
Floating Rate Notes intended to form a single series with the Floating Rate Notes herein provided for unless such additional Floating Rate Notes will be fungible with the Floating Rate Notes herein provided for, for U.S. federal income tax purposes.

 Section 2.04. Global Notes. Upon their original issuance, the Floating Rate Notes will be represented by one or more Global
Securities registered in the name of Cede & Co., the nominee of the Depositary. The Company will deposit the Global Securities with the Depositary or its custodian and register the Global Securities in the name of Cede & Co. 

Section 2.05. Interest. (a) Interest on the Floating Rate Notes will accrue at a per annum rate equal to LIBOR, as determined
by the Calculation Agent (as defined herein), plus 0.75%. The Calculation Agent will set the initial interest rate on August 19, 2014 and reset the interest rate on each interest payment date (each such date, an “Interest Reset
Date”); provided that if notice of redemption of the Floating Rate Notes has been given pursuant to Section 5.01(d), the interest rate thereon on the date of such notice will remain in effect through the applicable 2017 Redemption
Date (as defined below). The second London business day preceding an Interest Reset Date will be the “Interest Determination Date” for that Interest Reset Date. The interest rate in effect on each date that is not an Interest Reset Date
will be the interest rate determined as of the Interest Determination Date pertaining to the immediately preceding Interest Reset Date. The interest rate in effect on any day that is an Interest Reset Date will be the interest rate determined as of
the Interest Determination Date pertaining to the Interest Reset Date. Interest shall be computed on the basis of the actual number of days in the relevant interest period and a 360-day year. 

  
 2 








 (b) (i) Interest on the Floating Rate Notes will accrue from and including August 19, 2014,
to, but excluding, the first interest payment date and thereafter from and including the immediately preceding interest payment date to which interest has been paid or duly provided for to, but excluding, the next interest payment date. Interest on
the Floating Rate Notes shall be payable quarterly in arrears and the interest payment dates on which such interest shall be payable are February 15, May 15, August 15 and November 15, beginning on November 15,
2014; and the Regular Record Date for the interest payable on any interest payment date is the close of business on the February 1, May 1, August 1 or November 1 (whether or not a Business Day), as the case may be,
immediately preceding the relevant interest payment date. 
 (ii) If any interest payment date for the Floating Rate Notes
(other than the interest payment date falling on the maturity date of the Floating Rate Notes) falls on a day that is not a Business Day, the required payment on that day will be due on the next succeeding Business Day, except that if such next
succeeding Business Day falls in the next succeeding calendar month, the required payment on that day will be due on the immediately preceding Business Day. 

(iii) If the maturity date of the Floating Rate Notes falls on a day that is not a Business Day, the required payment on that
day need not be made on such maturity date, but may be made on the next succeeding Business Day with the same force and effect as if made on the maturity date, and no interest will accrue on the amounts so payable for the period from and after the
maturity date to the next succeeding Business Day. 
 (c) The following defined terms used in this Article Two shall, unless the context
otherwise requires, have the meanings specified below. 
 “Calculation Agent” means UMB Bank & Trust, N.A., a national
banking association organized and existing under the laws of the United States of America, and its successors and assigns. The Calculation Agent shall serve as the calculation agent hereunder unless and until a successor calculation agent is
appointed by the Company. 
 “LIBOR” will be determined by the Calculation Agent in accordance with the following provisions: 

(i) With respect to any Interest Determination Date, LIBOR will be the rate for deposits in United States dollars having a
maturity of three months commencing on the first day of the applicable interest period that appears on Reuters Page LIBOR01 as of 11:00 a.m., London time, on that Interest Determination Date. If, on an Interest Determination Date, such rate does not
appear on Reuters Page LIBOR01 as of 11:00 a.m., London time, or if Reuters Page LIBOR01 is not available on such date, the Calculation Agent will obtain such rate from Bloomberg L.P.’s page “BBAM.” If no rate appears on Reuters Page
LIBOR01 or Bloomberg L.P. page BBAM as of approximately 11:00 a.m., London time, on such Interest Determination Date, LIBOR for that Interest Determination Date will be determined in accordance with the provisions described in (ii) below. 

  
 3 








 (ii) With respect to an Interest Determination Date on which no rate appears on
Reuters Page LIBOR01 or Bloomberg L.P. page BBAM, as specified in (i) above, the Calculation Agent will request the principal London offices of each of four major reference banks in the London interbank market, as selected by the Calculation
Agent (after consultation with the Company), to provide the Calculation Agent with its offered quotation for deposits in United States dollars for the period of three months, commencing on the first day of the applicable interest period, to prime
banks in the London interbank market at approximately 11:00 a.m., London time, on that Interest Determination Date and in a principal amount that is representative for a single transaction in United States dollars in that market at that time. If at
least two quotations are provided, then LIBOR on that Interest Determination Date will be the arithmetic mean of those quotations. If fewer than two quotations are provided, then LIBOR on the Interest Determination Date will be the arithmetic mean
of the rates quoted at approximately 11:00 a.m., in The City of New York, on the Interest Determination Date by three major banks in The City of New York selected by the Calculation Agent (after consultation with the Company) for loans in United
States dollars to leading European banks, having a three-month maturity and in a principal amount that is representative for a single transaction in United States dollars in that market at that time. If, however, the banks selected by the
Calculation Agent are not providing quotations in the manner described by the previous sentence, LIBOR determined as of that Interest Determination Date will be LIBOR in effect on that Interest Determination Date. 

“Reuters Page LIBOR01” means the display designated on page LIBOR01 by Reuters Group plc (or such other page as may replace the
LIBOR01 page on that service (or any successor service) or such other service as may be nominated by the British Bankers’ Association for the purpose of displaying London interbank offered rates for U.S. dollar deposits). 

(d) All percentages resulting from any calculation of the interest rate on the Floating Rate Notes will be rounded to the nearest one
hundred-thousandth of a percentage point with five one millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and all dollar amounts used in or resulting from such calculation on
the Floating Rate Notes will be rounded to the nearest cent (with one-half cent being rounded upward). Each calculation of the interest rate on the Floating Rate Notes by the Calculation Agent will (in the absence of manifest error) be final and
binding on the Holders of the Floating Rate Notes and the Company. 
 Section 2.06. Authorized Denominations. The Floating Rate
Notes shall be issuable in denominations of $2,000 and integral multiples of $1,000 in excess thereof. 
 Section 2.07.
Redemption. The Floating Rate Notes are subject to redemption at the option of the Company as described in Article Five hereof. 

Section 2.08. Appointment of Agents. (a) The Trustee will initially be the Security Registrar and Paying Agent for the
Floating Rate Notes and will act as such only at its corporate 

  
 4 








 
trust offices in the City of St. Louis, State of Missouri. So long as any of the Floating Rate Notes remain outstanding, there shall at all times be a calculation agent, which shall initially be
the Calculation Agent. If the Calculation Agent is unable or unwilling to continue to act as the calculation agent or if it fails to calculate properly the interest rate on the Floating Rate Notes for any interest period, the Company will appoint
another leading commercial or investment bank engaged in the London interbank market to act as calculation agent in its place. Any such calculation agent may not resign its duties without a successor having been appointed. 

Section 2.09. Satisfaction and Discharge. If the Company discharges its obligations under the Floating Rate Notes in accordance
with Section 701 of the Indenture, the Company shall calculate the amount it must irrevocably deposit with the Trustee by assuming that the interest rate on the Floating Rate Notes through the maturity date or 2017 Redemption Date, as
applicable, will be the interest rate in effect on the date that the Company deposits funds with the Trustee.

interest on the 2044 Notes being redeemed to, but excluding, such 2044 Redemption Date.

set forth in such Officer’s Certificate.

The Laclede Group, Inc., a corporation duly organized and existing under the laws of Missouri (herein called the “Company”, which
term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co. or registered assigns, the principal sum of [—]
DOLLARS ($[—]) on August 15, 2017, and to pay interest thereon from August 19, 2014 or from the most recent interest payment date to which interest has been paid or duly provided for,
quarterly in arrears, on February 15, May 15, August 15 and November 15 in each year, beginning November 15, 2014 at the rate per annum provided below, until the principal hereof is paid or made available for
payment. 
 This Security will bear interest at a per annum rate equal to LIBOR, as determined by the Calculation Agent, plus 0.75%. The
Calculation Agent will set the initial interest rate on August 19, 2014 and reset the interest rate on each interest payment date (each such date, an “Interest Reset Date”); provided that if notice of redemption of this Security has
been given pursuant to the Indenture, the interest rate thereon on the date of such notice will remain in effect through the 

  
 A-1 








 
applicable Redemption Date. The second London business day preceding an Interest Reset Date will be the “Interest Determination Date” for that Interest Reset Date. The interest rate in
effect on each date that is not an Interest Reset Date will be the interest rate determined as of the Interest Determination Date pertaining to the immediately preceding Interest Reset Date. The interest rate in effect on any day that is an Interest
Reset Date will be the interest rate determined as of the Interest Determination Date pertaining to the Interest Reset Date. Interest shall be computed on the basis of the actual number of days in the relevant interest period and a 360-day year.

 The interest so payable, and punctually paid or duly provided for, on any interest payment date will, as provided in such Indenture, be
paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the February 1, May 1, August 1 or
November 1 (whether or not a Business Day), as the case may be, immediately preceding such interest payment date. Any such interest not so punctually paid or duly provided for will 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 whereof 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. 

UMB Bank & Trust, N.A., a national banking association organized and existing under the laws of the United States of America shall
act as calculation agent (together with its successors in that capacity, the “Calculation Agent”) in connection with the Securities. The Calculation Agent shall serve as the calculation agent hereunder unless and until a successor
calculation agent is appointed by the Company. 
 “LIBOR” will be determined by the Calculation Agent in accordance with the
following provisions: 
 (i) With respect to any Interest Determination Date, LIBOR will be the rate for deposits in United
States dollars having a maturity of three months beginning on the first day of the applicable interest period that appears on Reuters Page LIBOR01 as of 11:00 a.m., London time, on that Interest Determination Date. If, on an Interest Determination
Date, such rate does not appear on Reuters Page LIBOR01 as of 11:00 a.m., London time, or if Reuters Page LIBOR01 is not available on such date, the Calculation Agent will obtain such rate from Bloomberg L.P.’s page “BBAM.” If no rate
appears on Reuters Page LIBOR01 or Bloomberg L.P. page BBAM as of approximately 11:00 a.m., London time, on such Interest Determination Date, LIBOR for that Interest Determination Date will be determined in accordance with the provisions described
in (ii) below. 
 (ii) With respect to an Interest Determination Date on which no rate appears on Reuters Page LIBOR01
or Bloomberg L.P. page BBAM, as specified in (i) above, the Calculation Agent will request the principal London offices of each of four major reference 

  
 A-2 








 
banks in the London interbank market, as selected by the Calculation Agent (after consultation with the Company), to provide the Calculation Agent with its offered quotation for deposits in
United States dollars for the period of three months, commencing on the first day of the applicable interest period, to prime banks in the London interbank market at approximately 11:00 a.m., London time, on that Interest Determination Date and in a
principal amount that is representative for a single transaction in United States dollars in that market at that time. If at least two quotations are provided, then LIBOR on that Interest Determination Date will be the arithmetic mean of those
quotations. If fewer than two quotations are provided, then LIBOR on the Interest Determination Date will be the arithmetic mean of the rates quoted at approximately 11:00 a.m., in The City of New York, on the Interest Determination Date by three
major banks in The City of New York selected by the Calculation Agent (after consultation with the Company) for loans in United States dollars to leading European banks, having a three-month maturity and in a principal amount that is representative
for a single transaction in United States dollars in that market at that time. If, however, the banks selected by the Calculation Agent are not providing quotations in the manner described by the previous sentence, LIBOR determined as of that
Interest Determination Date will be LIBOR in effect on that Interest Determination Date. 
 “Reuters Page LIBOR01” means the
display designated on page LIBOR01 by Reuters Group plc (or such other page as may replace the LIBOR01 page on that service (or any successor service) or such other service as may be nominated by the British Bankers’ Association for the purpose
of displaying London interbank offered rates for U.S. dollar deposits). 
 All percentages resulting from any calculation of the interest
rate on the Securities will be rounded to the nearest one hundred-thousandth of a percentage point with five one millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and all
dollar amounts used in or resulting from such calculation on the Securities will be rounded to the nearest cent (with one-half cent being rounded upward). Each calculation of the interest rate on the Securities by the Calculation Agent will (in the
absence of manifest error) be final and binding on the Holders of the Securities and the Company. 
 Payment of the principal of (and
premium, if any) and interest on this Security will be made at the office or agency of the Company maintained for that purpose in the City of St. Louis, State of Missouri, in such coin or currency of the United States as at the time of payment is
legal tender for payment of public and private debts. 
 All payments of principal, premium, if any, and interest in respect of this
Security will be made by the Company in immediately available funds. 
 Reference is hereby made to the further provisions of this Security
set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place. 

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature of one
of its authorized signatories, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

 [Reverse of Security] 

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be
issued in one or more series under an Indenture, dated as of August 19, 2014 as supplemented by the first supplemental indenture dated as of August 19, 2014 (herein called the “Indenture”, which then shall have the meaning

Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated

At the Company’s option, the Securities of this series may be redeemed (the date of any such redemption, a “Redemption Date”),
in whole or in part, at any time and from time to time, on or after August 15, 2016 at a redemption price equal to 100% of the principal amount of the Securities being redeemed on the relevant Redemption Date (the “Redemption Price”);
plus accrued and unpaid interest on the Securities being redeemed to, but excluding, such Redemption Date. 
 Once notice of redemption is
mailed by the Company, the Securities called for redemption will become due and payable on the applicable Redemption Date at the Redemption Price. 

Notice of any redemption of the Securities shall be given in the manner and otherwise in accordance with the provisions of Section 404 of
the Indenture to each Holder of Securities to be redeemed, at his address appearing in the Security Register, and that any such notice in lieu of stating the applicable Redemption Price, shall state the manner in which such Redemption Price shall be
calculated. If the Company has given notice of redemption as provided in the Indenture and funds for the redemption of the Securities called for redemption have been made available on the Redemption Date referred to in that notice, such Securities
will cease to bear interest on such Redemption Date (unless the Company defaults in the payment of the Redemption Price and accrued and unpaid interest). Any interest accrued to such Redemption Date will be paid as specified in such notice. 

In the event that (i) the Company does not complete the Alagasco Acquisition on or prior to November 15, 2015 or (ii) the
Purchase Agreement is terminated at any time prior to November 15, 2015, then the Company shall redeem all of the Securities on the Special Mandatory Redemption Date at the Special Mandatory Redemption Price, plus accrued and unpaid interest
to, but not including, the Special Mandatory Redemption Date. The Company shall cause a notice of special mandatory redemption to be distributed, with a copy to the Trustee, within ten Business Days after the occurrence of the event triggering the
special mandatory redemption to each holder of Securities. If funds sufficient to pay the Special Mandatory Redemption Price of all Securities to be redeemed on the Special Mandatory Redemption Date are deposited with the Trustee on or before such
Special Mandatory Redemption Date, plus accrued and unpaid interest, if any, to the Special Mandatory Redemption 

  
 A-5 








 
Date, the Securities will cease to bear interest. The notice of special mandatory redemption shall include the information required by Section 404 of the Indenture, and, notwithstanding such
Section 404, may be given less than 30 days prior to the Special Mandatory Redemption Date, but in no event fewer than five Business Days prior thereto. 

For purposes of the preceding paragraph, the following definitions shall apply: 

“Alagasco Acquisition” means the consummation of the transactions contemplated by the Purchase Agreement. 

“Purchase Agreement” means that certain Stock Purchase Agreement, dated as of April 5, 2014, by and among the Company, Energen

 “Special Mandatory Redemption Price”
means a redemption price equal to 101% of the aggregate principal amount of the Securities.

covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture. 

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series
may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture permits, with certain
exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of a majority in principal amount of all series at the time Outstanding affected thereby (voting as one class). The Indenture contains provisions permitting the Holders of not less than a majority in principal
amount of the Outstanding Securities of all series with respect to which any default under the Indenture shall have occurred and be continuing (voting as one class), on behalf of the Holders of all the Outstanding Securities of such series, to
waive, with certain exceptions, such past default with respect to such series and its consequences. The Indenture also permits the Holders of not less than a majority in principal amount of the Outstanding Securities of any series, on behalf of the
Holders of all Outstanding Securities of such series, to waive compliance by the Company with certain provisions of the Indenture. 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 and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any
proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to
the Securities of this series, the Holders of not less than a majority in principal amount of the 

  
 A-6

such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or
interest hereon on or after the respective due dates expressed herein.

Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency,
herein prescribed. 
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is

authorized denomination, as requested in writing by the Holder surrendering the same. 
 No service charge shall be made for any such
registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or in any supplemental indenture, or in this Security, or because of the creation of any indebtedness

 [Reverse of Security] 

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be
issued in one or more series under an Indenture, dated as of August 19, 2014 as supplemented by the first supplemental indenture dated as of August 19, 2014 (herein called the “Indenture”, which then shall have the meaning
assigned to it in such instrument) between the Company and UMB Bank & Trust, N.A., as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the
Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated
and delivered. This Security is one of the series designated on the face hereof initially limited in aggregate principal amount to $125,000,000. 

At the Company’s option, the Securities of this series may be redeemed (the date of any such redemption, a “Redemption Date”)
(x) in whole or in part at any time and from time to time prior to July 15, 2019 at a redemption price (the “Redemption Price”) of the Securities equal to the greater of the following amounts: 

(a) 100% of the principal amount of the Securities being redeemed on the applicable Redemption Date, and 

(b) the sum of the present value of the remaining scheduled payments of principal and interest on the Securities being redeemed
on such Redemption Date (not including the amount, if any, of accrued and unpaid interest to, but excluding, such Redemption Date) discounted to such Redemption Date on a semi-annual basis at the Treasury Rate (as defined below), as determined by
the Independent Investment Banker (as defined below), plus 15 basis points; 
 and (y) in whole only, at any time on or after July 15, 2019
at a redemption price equal to 100% of the principal amount of the Securities being redeemed on the relevant Redemption Date; plus, in each case, accrued and unpaid interest on the Securities being redeemed to, but excluding, such Redemption Date.

 The Redemption Price will be calculated on the basis of a 360-day year consisting of twelve 30-day months. Once notice of redemption is
mailed by the Company, the Securities called for redemption will become due and payable on the applicable Redemption Date at the applicable Redemption Price. 

Notice of any redemption of the Securities shall be given in the manner and otherwise in accordance with the provisions of Section 404 of
the Indenture to each Holder of Securities to be redeemed, at his address appearing in the Security Register, and that any such notice in lieu of stating the applicable Redemption Price, shall state the manner in which such Redemption Price shall be
calculated. If the Company has given notice of redemption as provided in the Indenture and funds for the redemption of the Securities called for redemption have been made available on the Redemption Date referred to in that notice, such Securities
will cease to bear interest on such Redemption Date (unless the Company defaults in the payment of the applicable Redemption Price and accrued and unpaid interest). Any interest accrued to such Redemption Date will be paid as specified in such
notice.
