Section 2.05. Redemption Provisions. At any time prior to April 15, 2029 (the date that is one month prior to the maturity date of the Senior Notes (the “Par Call Date”)), the Company, at its option, may redeem the Senior Notes due 2029, in whole or from time to time in part, upon notice as provided in the Indenture, at a “make-whole” redemption price equal to the greater of (i) 100% of the principal amount of the Senior Notes due 2029 being redeemed or (ii) (a) the sum of the present values of the remaining scheduled payments of principal and interest on the Senior Notes being redeemed discounted to the redemption date (assuming the Senior Notes 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 15 basis points less (b) interest accrued to the date fixed for redemption, plus, in each case, accrued and unpaid interest thereon to the date fixed for redemption. At any time on or after the Par Call Date, the Company, at its option, may redeem the Senior Notes due 2029, in whole or from time to time in part, upon notice as provided in the Indenture, at a redemption price equal to 100% of the principal amount of the Senior Notes due 2029 being redeemed, plus accrued and unpaid interest thereon to the date fixed for redemption.

"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:

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 Trustee shall have no responsibility to calculate the redemption price.

The Senior Notes due 2029 shall not be subject to any sinking fund.

OGE ENERGY CORP.

5.45% SENIOR NOTE, SERIES DUE MAY 15, 2029

OGE Energy Corp., a corporation of the State of Oklahoma (the “Company”), for value received hereby promises to pay to Cede & Co. or registered assigns, the principal sum of

THREE HUNDRED FIFTY MILLION DOLLARS

on the Maturity Date set forth above, and to pay interest thereon from the Original Issue Date (or if this Global Security has two or more Original Issue Dates, interest shall, beginning on each such Original Issue Date, begin to accrue for that part of the principal amount to which that Original Issue Date is applicable) set forth above or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears on May 15 and November 15 of each year, commencing on November 15, 2024, at the per annum Interest Rate set forth above, until the principal hereof is paid or made available for payment. No interest shall accrue on the Maturity Date, so long as the principal amount of this Global Security is paid on the Maturity Date. The interest so payable and punctually paid or duly provided for on any such Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Global Security is registered at the close of business on the Regular Record Date for such interest, which shall be the May 1 and November 1, as the case may be, next preceding such Interest Payment Date, provided that the first Interest Payment Date for any part of this Global Security, the Original Issue Date of which is after a Regular Record Date but prior to the applicable Interest Payment Date, shall be the Interest Payment Date following the next succeeding Regular Record Date; and provided that interest payable on the Maturity Date set forth above or, if applicable, upon redemption, repayment or acceleration, shall be payable to the Person to whom principal shall be payable. Except as otherwise provided in the Indenture (as defined below), any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date and shall be paid to the Person in whose name this Global Security 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 Securityholders not more than fifteen days or fewer than ten days prior to such Special Record Date. On or before 10:00 a.m., New York City time, or such other time as shall be agreed upon between the Trustee and the Depositary, of the day on which such payment of interest is due on this Global Security (other than maturity), the Trustee shall pay to the Depositary such interest in same day funds. On or before 10:00 a.m., New York City time, or such other time as shall be agreed upon between the Trustee and the Depositary, of the day on which principal, interest payable at maturity and premium, if any, is due on this Global Security, the Trustee shall deposit with the Depositary the amount equal to the principal, interest payable at maturity and premium, if any, by wire transfer into the account specified by the Depositary. As a condition to the payment, on the Maturity Date or upon redemption, repayment or acceleration, of any part of the principal and applicable premium of this Global Security, the Depositary shall surrender, or cause to be surrendered, this Global Security to the Trustee, whereupon a new Global Security shall be issued to the Depositary.

This Global Security is a global security in respect of a duly authorized issue of 5.45% Senior Notes, Series due May 15, 2029 (the “Securities of this Series,” which term includes any Global Securities representing such Securities) of the Company issued and to be issued under an Indenture dated as of November 1, 2004 between the Company and BOKF, NA as successor trustee (the “Trustee,” which term includes any subsequent successor Trustee under the Indenture) and indentures supplemental thereto (collectively, the “Indenture”). Under the Indenture, one or more series of debt securities may be issued and, as used herein, the term “Securities” refers to the Securities of this Series and any other outstanding series of Securities. Reference is hereby made to the Indenture for a more complete statement of the respective rights, limitations of rights, duties and immunities under the Indenture of the Company, the Trustee and the Securityholders and of the terms upon which the Securities are and are to be authenticated and delivered. This Global Security has been issued in respect of the series designated on the first page hereof.

Each Security of this Series shall be dated and issued as of the date of its authentication by the Trustee and shall bear an Original Issue Date or Dates. Each Security or Global Security issued upon transfer, exchange or substitution of such Security or Global Security shall bear the Original Issue Date or Dates of such transferred, exchanged or substituted Security or Global Security, as the case may be.

At any time prior to April 15, 2029 (the date that is one month prior to the maturity date of the Securities of this Series (the “Par Call Date”)), the Company, at its option, may redeem this Global Security, in whole or from time to time in part, at a “make-whole” redemption price equal to the greater of: (i) 100% of the principal amount of this Global Security being redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on this Global Security being redeemed that would be due if the Global Security matured on the Par Call Date (not including any portion of such payments of interest accrued to the date fixed for redemption) discounted to the date fixed for redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 15 basis points, plus, in each case, accrued and unpaid interest thereon to the date fixed for redemption. At any time on or after the Par Call Date, the Company, at its option, may redeem this Global Security, in whole or from time to time in part, at a redemption price equal to 100% of the principal amount of this Global Security being redeemed, plus accrued and unpaid interest thereon to the date fixed for redemption.

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

The treasury rate shall be determined by us 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 Trustee shall have no responsibility to calculate the redemption price.

Notice of redemption will be given by mail to Holders of Securities of this Series not less than 30 or more than 60 days prior to the date fixed for redemption, all as provided in the Indenture. In the event of redemption of this Global Security in part only, a new Global Security or Securities of like tenor and series for the unredeemed interest hereof will be issued in the name of the Securityholder hereof upon the surrender hereof.

Interest payments for this Global Security shall be computed and paid on the basis of a 360-day year of twelve 30-day months. If any Interest Payment Date or date on which the principal of this Global Security is required to be paid is not a Business Day, then payment of principal, premium or interest need not be made on such date but may be made on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date or date on which the principal of this Global Security is required to be paid and, in the case of timely payment thereof, no interest shall accrue for the period from and after such Interest Payment Date or the date on which the principal of this Global Security is required to be paid.

The Company, at its option, and subject to the terms and conditions provided in the Indenture, will be discharged from any and all obligations in respect of the Securities (except for certain obligations including obligations to register the transfer or exchange of Securities, replace stolen, lost or mutilated Securities, maintain paying agencies and hold monies for payment in trust, all as set forth in the Indenture) if the Company deposits with the Trustee money, U.S. Government Obligations which through the payment of interest thereon and principal thereof in accordance with their terms will provide money, or a combination of money and U.S. Government Obligations, in any event in an amount sufficient, without reinvestment, to pay all the principal of and any premium and interest on the Securities on the dates such payments are due in accordance with the terms of the Securities.

If an Event of Default shall occur and be continuing, the principal of the Securities 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 modifications of the rights and obligations of the Company and the rights of the Securityholders 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 outstanding Securities. Any such consent or waiver by the Holder of this Global Security shall be conclusive and binding upon such Holder and upon all future Holders of this Global Security and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu thereof whether or not notation of such consent or waiver is made upon the Security.

As set forth in and subject to the provisions of the Indenture, no Holder of any Securities will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default with respect to such Securities, the Holders of not less than a majority in principal amount of the outstanding Securities affected by such Event of Default shall have made written request and offered reasonable indemnity to the Trustee to institute such proceeding as Trustee and the Trustee shall have failed to institute such proceeding within 60 days; provided that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of and any premium or interest on this Global Security on or after the respective due dates expressed here.

No reference herein to the Indenture and to provisions of this Global 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 Global Security at the times, places and rates and the coin or currency prescribed in the Indenture.

As provided in the Indenture and subject to certain limitations therein set forth, this Global Security may be transferred only as permitted by the legend hereto.

If at any time the Depositary for this Global Security notifies the Company that it is unwilling or unable to continue as Depositary for this Global Security or if at any time the Depositary for this Global Security shall no longer be eligible or in good standing under the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation, the Company shall appoint a successor Depositary with respect to this Global Security. If a successor Depositary for this Global Security is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such ineligibility, the Company’s election to issue this Security in global form shall no longer be effective with respect to this Global Security and the Company will execute, and the Trustee,

upon receipt of a Company Order for the authentication and delivery of individual Securities of this Series in exchange for this Global Security, will authenticate and deliver individual Securities of this Series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of this Global Security.

The Company may at any time and in its sole discretion determine that all Securities of this Series (but not less than all) issued or issuable in the form of one or more Global Securities shall no longer be represented by such Global Security or Securities. In such event, the Company shall execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of individual Securities of this Series in exchange for such Global Security, shall authenticate and deliver, individual Securities of this Series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of such Global Security or Securities in exchange for such Global Security or Securities.

Under certain circumstances specified in the Indenture, the Depositary may be required to surrender any two or more Global Securities which have identical terms (but which may have differing Original Issue Dates) to the Trustee, and the Company shall execute and the Trustee shall authenticate and deliver to, or at the direction of, the Depositary a Global Security in principal amount equal to the aggregate principal amount of, and with all terms identical to, the Global Securities surrendered thereto and that shall indicate all Original Issue Dates and the principal amount applicable to each such Original Issue Date.

The Indenture and the Securities shall be governed by, and construed in accordance with, the laws of the State of Oklahoma.

Unless the certificate of authentication hereon has been executed by the Trustee, directly or through an Authenticating Agent by manual signature of an authorized signatory, this Global Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

All terms used in this Global Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture unless otherwise indicated herein.
