Notes under the Indenture, or (iii) upon the occurrence and continuation of an Event of Default and the Depository notifies the Trustee of its decision to exchange the Global Note for Definitive Notes.

therein.

 ONE Gas, Inc., a corporation duly organized and existing under the laws of Oklahoma (herein called the “Company,”
which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to , or registered assigns, the principal sum of THREE HUNDRED MILLION DOLLARS, and to pay interest thereon from
August 8, 2022 or from the most recent Interest Payment Date (as defined below) to which interest has been paid or duly provided for, semi-annually on March 1 and September 1 (each such date, an “Interest Payment Date”) and
in each year, commencing March 1, 2023, at the rate of 4.25% per annum, until the principal hereof is paid or made available for payment, and (to the extent that the payment of such interest shall be legally enforceable) at the same rate on any
overdue principal and premium and on any overdue installment of interest. 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 (as defined below) for such interest, which shall be (a) the February 15 or August 15 (whether or not a Business Day),

 [REVERSE OF NOTE] 

ONE GAS, INC. 
 4.25% Senior Notes
Due 2032 
 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 January 27, 2014, as it may be supplemented or amended from time to time, including without limitation Supplemental Indenture No. 6 (herein called the
“Indenture”), between the Company and U.S. Bank Trust Company, National Association (successor in interest to U.S. Bank National Association), as 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 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, limited in aggregate principal
amount to $300,000,000. 
 Prior to June 1, 2032 (which is the date that is three months prior to the maturity date of the Securities) (the
“Par Call Date”), the Company may redeem the Securities at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal
places) equal to the greater of: 
 (1)(a) the sum of the present values of the remaining scheduled payments of principal and interest
thereon discounted to the redemption date (assuming the Securities matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve
30-day months) at the Treasury Rate (as defined below) plus 25 basis points less (b) interest accrued and unpaid thereon to the date of redemption, and 

(2) 100% of the principal amount of the Securities to be redeemed, 

plus, in either case, accrued and unpaid interest thereon to, but excluding, the redemption date. 

On or after the Par Call Date, the Company may redeem the Securities at its option, in whole or in part, at any time and from time to time, at a redemption
price equal to 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date. 

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.

 The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are
posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent
statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the
caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: 

(1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the
“Remaining Life”); or 
 (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining
Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall
interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or 

 (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the
Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal
to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date. 
 If on the third business day
preceding the redemption date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business
day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there
are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select
the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of
the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United
States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon
the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places. 

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

 The redemption price will be quoted to the Trustee in writing and the Trustee shall have no duty to determine, or verify the calculation of, the
redemption price. 
 The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive
covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth therein. 
 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 to be affected under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the
Holders of specified percentages in principal amount of the Securities at the time Outstanding of any series, on behalf of the Holders of all Securities of such series, 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 herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 

No reference herein to the Indenture and no provision of this 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 registerable in the Security Register,
upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, 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 and of like tenor, of
authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

 The Securities of this series are issuable only in registered form without coupons in denominations of
$2,000 and whole 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 this series
and of like tenor of a different authorized denomination, as requested 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. 

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture. 

This Security shall be governed by and construed in accordance with the laws of the State of New York.EX-10.1
