 NOW, THEREFORE, THIS SUPPLEMENTAL INDENTURE WITNESSETH: 
 For and in consideration

SECTION 1.1 RELATION TO SENIOR INDENTURE. This Supplemental Indenture constitutes an integral part of the Senior Indenture. 

SECTION 1.2 DEFINITIONS. The following definitions applicable to the series of Debt Securities provided for herein shall be in addition

 “2022 Notes” shall have the meaning set forth in
Section 2.1 of this Supplemental Indenture. 
 “2042 Notes” shall have the meaning set forth in
Section 2.1 of this Supplemental Indenture. 
 “Adjusted Treasury Rate” means, with respect to any
Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Optional Redemption Comparable Treasury Issue, calculated using a price for the Optional Redemption Comparable Treasury Issue (expressed as a percentage
of its principal amount) equal to the Optional Redemption Comparable Treasury Price for such Redemption Date. 

“Independent Investment Banker” means an independent investment banking institution of national standing appointed by

 [Reverse of Security] 

DEVON ENERGY CORPORATION 
 This Debt Security is one of a duly authorized issue of securities of the Company (herein called the “Debt Securities”), issued and to be issued in one or more series under an Indenture, dated
as of July 12, 2011, as supplemented by Supplemental Indenture No. 2, dated as of May 14, 2012 (as so supplemented, herein called the “Indenture”), between the Company and UMB Bank, National Association, as Trustee (herein
called the “Trustee,” which term includes any successor trustee under the Indenture with respect to the series of which this Debt Security is a part), 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 Debt Securities, and of the terms upon which the Debt Securities are, and are to be, authenticated and
delivered. This Debt Security is one of the duly authorized series of Debt Securities designated on the face hereof, and the aggregate principal amount of the Debt Securities to be issued under such series is initially limited to $750,000,000,
subject to the Company’s right to increase such limit as provided in the Indenture (except for Debt Securities authenticated and delivered upon transfer of, or in exchange for, or in lieu of other Debt Securities). All terms used in this Debt
Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture. 
 If an Event of
Default, as defined in the Indenture, with respect to the Debt Securities of this series, shall occur and be continuing, the principal amount of the Debt Securities of this series and interest accrued thereon may be declared due and payable in the
manner and with the effect provided in the Indenture. 
 The Company may redeem this Debt Security prior to one month before the
Stated Maturity Date, at any time, in whole or in part, at the Company’s option, at a redemption price equal to the greater of (1) 100% of the principal amount of this Debt Security then Outstanding to be redeemed or (2) the sum of
the present values of the remaining scheduled payments of principal and interest hereon (exclusive of interest accrued to the Redemption Date) from the Redemption Date to the Stated Maturity Date computed by discounting such payments to the
Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of 20 basis points plus the Adjusted Treasury Rate, as determined by an Independent Investment Banker, on the third
Business Day prior to the Redemption Date plus, in each case, accrued and unpaid interest, if any, up to, but not including, the Redemption Date. On or after the date that is one month prior to the Stated Maturity Date, the Company may redeem this
Debt Security, at any time, in whole or in part, at the Company’s option at a redemption price equal to 100% of the principal amount of this Debt Security, plus accrued and unpaid interest to, but not including, the Redemption Date. 

Notice of redemption will be given by mail to Holders of Debt Securities, not less than 30 nor more than 60 days prior to the Redemption
Date, all as provided in the Indenture. 

  
 A-4









 This Debt Security may be redeemed in part only in multiples of $2,000 or any integral
multiples of $1,000 in excess of $2,000. In the event of redemption of this Debt Security in part only, a new Debt Security or Debt Securities for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation
hereof. 
 The Indenture permits, with certain exceptions as provided therein, the amendment thereof and the modification of the
rights and obligations of the Company and the rights of the Holders of the Debt Securities under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal amount
of all Debt Securities issued under the Indenture at the time Outstanding and directly affected thereby. The Indenture also contains provisions permitting the Holders of not less than a majority of the aggregate principal amount of the Outstanding
Debt Securities, on behalf of the Holders of all such securities, to waive compliance by the Company with certain provisions of the Indenture. Furthermore, provisions in the Indenture permit the Holders of not less than a majority of the aggregate
principal amount, in certain instances, of the Outstanding Debt Securities of any series to waive, on behalf of all of the Holders of Debt Securities of such series, certain past defaults under the Indenture and their consequences. Any such consent
or waiver by the Holder of this Debt Security shall be conclusive and binding upon such Holder and upon all future Holders of this Debt Security and other Debt Securities 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 Debt Security. 
 No reference herein to the
Indenture and no provision of this Debt Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Debt Security at the times,
places and rate, and in the coin or currency, herein prescribed. 
 As provided in the Indenture and subject to certain
limitations therein and herein set forth, the transfer of this Debt Security is registrable in the Debt Security Register of the Company upon surrender of this Debt Security for registration of transfer at the office or agency of the Company in any
place where the principal of, premium, if any, and interest on this Debt Security are payable, duly endorsed by, or accompanied by a written instrument of transfer, in form satisfactory to the Company and the Debt Security Registrar, duly executed
by the Holder hereof or by his attorney duly authorized in writing, and thereupon one or more new Debt Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

 As provided in the Indenture and subject to certain limitations therein and herein set forth, this Debt Security is
exchangeable for a like aggregate principal amount of Debt Securities of different authorized denominations but otherwise having the same terms and conditions, as requested by the Holder hereof surrendering the same. 

The Debt Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and any integral
multiples of $1,000 in excess of $2,000. 
 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. 

  
 A-5









 Prior to due presentment of this Debt 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 Debt Security is registered as the owner hereof for all purposes, whether or not this Debt Security be overdue, and neither the Company, the Trustee nor
any such agent shall be affected by notice to the contrary. 
 No recourse shall be had for the payment of the principal of or
premium, if any, or the interest on this Debt Security, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any past, present or future stockholder,
employee, officer or director, as such, of the Company or of any successor, either directly or through the Company or any successor, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or
otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released. 
 The Indenture and the Debt Securities shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made and to be performed entirely in such State.

 Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has
caused “CUSIP” numbers to be printed on the Debt Securities of this series as a convenience to the Holders of such Debt Securities. No representation is made as to the correctness or accuracy of such CUSIP numbers as printed on the Debt
Securities, and reliance may be placed only on the other identification numbers printed hereon.

 [Reverse of Security] 

DEVON ENERGY CORPORATION 
 This Debt Security is one of a duly authorized issue of securities of the Company (herein called the “Debt Securities”), issued and to be issued in one or more series under an Indenture, dated
as of July 12, 2011, as supplemented by Supplemental Indenture No. 2, dated as of May 14, 2012 (as so supplemented, herein called the “Indenture”), between the Company and UMB Bank, National Association, as Trustee (herein
called the “Trustee,” which term includes any successor trustee under the Indenture with respect to the series of which this Debt Security is a part), 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 Debt Securities, and of the terms upon which the Debt Securities are, and are to be, authenticated and
delivered. This Debt Security is one of the duly authorized series of Debt Securities designated on the face hereof, and the aggregate principal amount of the Debt Securities to be issued under such series is initially limited to $1,000,000,000,
subject to the Company’s right to increase such limit as provided in the Indenture (except for Debt Securities authenticated and delivered upon transfer of, or in exchange for, or in lieu of other Debt Securities). All terms used in this Debt
Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture. 
 If an Event of
Default, as defined in the Indenture, with respect to the Debt Securities of this series, shall occur and be continuing, the principal amount of the Debt Securities of this series and interest accrued thereon may be declared due and payable in the
manner and with the effect provided in the Indenture. 
 The Company may redeem this Debt Security prior to three months before
the Stated Maturity Date, at any time, in whole or in part, at the Company’s option, at a redemption price equal to the greater of (1) 100% of the principal amount of this Debt Security then Outstanding to be redeemed or (2) the sum
of the present values of the remaining scheduled payments of principal and interest hereon (exclusive of interest accrued to the Redemption Date) from the Redemption Date to the Stated Maturity Date computed by discounting such payments to the
Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of 25 basis points plus the Adjusted Treasury Rate, as determined by an Independent Investment Banker, on the third
Business Day prior to the Redemption Date plus, in each case, accrued and unpaid interest, if any, up to, but not including, the Redemption Date. On or after the date that is three months prior to the Stated Maturity Date, the Company may redeem
this Debt Security, at any time, in whole or in part, at the Company’s option at a redemption price equal to 100% of the principal amount of this Debt Security, plus accrued and unpaid interest to, but not including, the Redemption Date.

 Notice of redemption will be given by mail to Holders of Debt Securities, not less than 30 nor more than 60 days prior to the
Redemption Date, all as provided in the Indenture. 

  
 B-4









 This Debt Security may be redeemed in part only in multiples of $2,000 or any integral
multiples of $1,000 in excess of $2,000. In the event of redemption of this Debt Security in part only, a new Debt Security or Debt Securities for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation
hereof. 
 The Indenture permits, with certain exceptions as provided therein, the amendment thereof and the modification of the
rights and obligations of the Company and the rights of the Holders of the Debt Securities under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal amount
of all Debt Securities issued under the Indenture at the time Outstanding and directly affected thereby. The Indenture also contains provisions permitting the Holders of not less than a majority of the aggregate principal amount of the Outstanding
Debt Securities, on behalf of the Holders of all such securities, to waive compliance by the Company with certain provisions of the Indenture. Furthermore, provisions in the Indenture permit the Holders of not less than a majority of the aggregate
principal amount, in certain instances, of the Outstanding Debt Securities of any series to waive, on behalf of all of the Holders of Debt Securities of such series, certain past defaults under the Indenture and their consequences. Any such consent
or waiver by the Holder of this Debt Security shall be conclusive and binding upon such Holder and upon all future Holders of this Debt Security and other Debt Securities 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 Debt Security. 
 No reference herein to the
Indenture and no provision of this Debt Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Debt Security at the times,
places and rate, and in the coin or currency, herein prescribed. 
 As provided in the Indenture and subject to certain
limitations therein and herein set forth, the transfer of this Debt Security is registrable in the Debt Security Register of the Company upon surrender of this Debt Security for registration of transfer at the office or agency of the Company in any
place where the principal of, premium, if any, and interest on this Debt Security are payable, duly endorsed by, or accompanied by a written instrument of transfer, in form satisfactory to the Company and the Debt Security Registrar, duly executed
by the Holder hereof or by his attorney duly authorized in writing, and thereupon one or more new Debt Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

 As provided in the Indenture and subject to certain limitations therein and herein set forth, this Debt Security is
exchangeable for a like aggregate principal amount of Debt Securities of different authorized denominations but otherwise having the same terms and conditions, as requested by the Holder hereof surrendering the same. 

The Debt Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and any integral
multiples of $1,000 in excess of $2,000. 
 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. 

  
 B-5









 Prior to due presentment of this Debt 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 Debt Security is registered as the owner hereof for all purposes, whether or not this Debt Security be overdue, and neither the Company, the Trustee nor
any such agent shall be affected by notice to the contrary. 
 No recourse shall be had for the payment of the principal of or
premium, if any, or the interest on this Debt Security, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any past, present or future stockholder,
employee, officer or director, as such, of the Company or of any successor, either directly or through the Company or any successor, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or
otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released. 
 The Indenture and the Debt Securities shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made and to be performed entirely in such State.

 Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has
caused “CUSIP” numbers to be printed on the Debt Securities of this series as a convenience to the Holders of such Debt Securities. No representation is made as to the correctness or accuracy of such CUSIP numbers as printed on the Debt
Securities, and reliance may be placed only on the other identification numbers printed hereon.
