**ARTICLE TWO.**

&nbsp;&nbsp;&nbsp;&nbsp;**5.40% SENIOR NOTES, SERIES DUE JANUARY 15, 2033** 

Section 2.01. There shall be a series of Notes designated the "5.40% Senior Notes, Series due January 15, 2033" (the "Senior Notes due 2033"). The Senior Notes due 2033 shall be limited to $450,000,000 aggregate principal amount, except as provided in Section 2.08 hereof.

Section 2.02. Except as otherwise provided in Section 2.05 hereof, the principal amount of the Senior Notes due 2033 shall be payable on the stated maturity date of January 15, 2033.

Section 2.03. The Senior Notes due 2033 shall be dated their date of authentication as provided in the Indenture and shall bear interest from their date at the rate of 5.40% per annum, payable semi-annually in arrears on January 15 and July 15 of each year, commencing July 15, 2023. The Regular Record Dates with respect to such January 15 and July 15 interest payment dates shall be January 1 and July 1, respectively. Principal and interest shall be payable to the persons and in the manner provided in Sections 2.04 and 2.12 of the Indenture.

Section 2.04. The Senior Notes due 2033 shall be payable at the corporate trust office of the Trustee and at the offices of such paying agents as the Company may appoint by Company Order in the future.

Section 2.05. At any time prior to July 15, 2032 (the date that is six months prior to the maturity date of the Senior Notes (the "Par Call Date")), the Company, at its option, may redeem the Senior Notes due 2033, 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 2033 being redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Senior Notes due 2033 being redeemed that would be due if the Senior Notes due 2033 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 25 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 the Senior Notes due 2033, 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 2033 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

The Senior Notes due 2033 shall not be subject to any sinking fund.

Section 2.06. The Senior Notes due 2033 shall be issued in fully registered form without coupons in a minimum denomination of $2,000 and multiples of $1,000 in excess thereof.

Section 2.07. The Release Date (as defined in the Indenture) occurred on April 6, 1998. Accordingly, the Senior Notes due 2033 shall be issued as unsecured general obligations of the Company. The Senior Notes due 2033, and all other Notes issued or to be issued under the Indenture, will not be secured by First Mortgage Bonds of the Company and will not be entitled to the lien of or the benefits provided by the First Mortgage, which has been extinguished.

------

Section 2.08. The Senior Notes due 2033 may be reopened and additional notes of the Senior Notes due 2033 may be issued in excess of the limitation set forth in Section 2.01 hereof, provided that such additional notes will contain the same terms (including the maturity date and interest payment terms) as the other Senior Notes due 2033, except for the issue date, price to public and, if applicable, first date from which interest will accrue and the initial interest payment date. Any such additional Senior Notes due 2033, together with the other Senior Notes due 2033, shall constitute a single series for purposes of the Indenture.

Oklahoma Gas and Electric Company, 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

FOUR 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 Note 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 January 15 and July 15 of each year, commencing on July 15, 2023, 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 Note 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 Note is registered at the close of business on the Regular Record Date for such interest, which shall be the January 1 and July 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 Note, 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 Note 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 Noteholders 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 Note (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 Note, 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 Note, the Depositary shall surrender, or cause to be surrendered, this Global Note to the Trustee, whereupon a new Global Note shall be issued to the Depositary.

This Global Note is a global security in respect of a duly authorized issue of 5.40% Senior Notes, Series due January 15,

------

2033 (the "Notes of this Series," which term includes any Global Notes representing such Notes) of the Company issued and to be issued under an Indenture dated as of October 1, 1995 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 notes may be issued and, as used herein, the term "Notes" refers to the Notes of this Series and any other outstanding series of Notes. 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 Noteholders and of the terms upon which the Notes are and are to be authenticated and delivered. This Global Note has been issued in respect of the series designated on the first page hereof.

Each Note 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 Note or Global Note issued upon transfer, exchange or substitution of such Note or Global Note shall bear the Original Issue Date or Dates of such transferred, exchanged or substituted Note or Global Note, as the case may be.

At any time prior to July 15, 2032 (the date that is six months prior to the maturity date of the Senior Notes (the "Par Call Date")), the Company, at its option, may redeem this Global Note, 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 Note being redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on this Global Note being redeemed that would be due if the Global Note 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 25 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 Note, in whole or from time to time in part, at a redemption price equal to 100% of the principal amount of this Global Note 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 or by electronic communication (including e-mail) to Holders of Notes 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 Note in part only, a new Global Note or Notes of like tenor and series for the unredeemed interest hereof will be issued in the name of the Noteholder hereof upon the surrender hereof.

Interest payments for this Global Note 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 Note 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 Note 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 Note 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 Notes (except for certain obligations including obligations to register the transfer or exchange of Notes, replace stolen, lost or mutilated Notes, 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 Notes on the dates such payments are due in accordance with the terms of the Notes.

If an Event of Default shall occur and be continuing, the principal of the Notes 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 Noteholders 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 Notes. Any such consent or waiver by the Holder of this Global Note shall be conclusive and binding upon such Holder and upon all future Holders of this Global Note and of any Note 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 Note.

As set forth in and subject to the provisions of the Indenture, no Holder of any Notes 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 Notes, the Holders of not less than a majority in principal amount of the outstanding Notes 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 Note on or after the respective due dates expressed here.

No reference herein to the Indenture and to provisions of this Global Note 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 Note 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 Note may be transferred only as permitted by the legend hereto.

If at any time the Depositary for this Global Note notifies the Company that it is unwilling or unable to continue as Depositary for this Global Note or if at any time the Depositary for this Global Note 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 Note. If a successor Depositary for this Global Note 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 Note in global form shall no longer be effective with respect to this Global Note and the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of individual Notes of this Series in

------

exchange for this Global Note, will authenticate and deliver individual Notes of this Series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of this Global Note.

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

Under certain circumstances specified in the Indenture, the Depositary may be required to surrender any two or more Global Notes 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 Note in principal amount equal to the aggregate principal amount of, and with all terms identical to, the Global Notes 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 Notes 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 Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

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

Oklahoma Gas and Electric Company

321 N. Harvey

Oklahoma City, Oklahoma 73101

Re: OG&E's Public Offering of 5.40% Senior Notes, Series due January 15, 2033

Ladies and Gentlemen:

We have acted as special Oklahoma counsel to Oklahoma Gas and Electric Company, an Oklahoma corporation (the "**Company**"), in connection with the issuance and sale by the Company of $450,000,000 aggregate principal amount of its 5.40% Senior Notes, Series due January 15, 2033 (the "**Senior Notes**"), issued pursuant to the Prospectus Supplement, dated January 3, 2023 (the "**Prospectus Supplement**") and filed with the United States Securities and Exchange Commission (the "**SEC**") on January 4, 2023, and the Prospectus dated May 6, 2021, filed as part of the shelf registration statement (File No. 333-255823-01) that automatically became effective under the Securities Act of 1933, as amended (including the rules and regulations thereunder, the "**Act**"), when filed with the SEC on May 6, 2021 (the "**Registration Statement**").

The Senior Notes were issued under the Indenture dated as of October 1, 1995 (the "**Base Indenture**") between the Company and BOKF, NA, as successor trustee (the "**Trustee**"), as supplemented 23 times, most recently by the Supplemental Indenture No. 23 thereto dated as of January 5, 2023 (the Base Indenture, as so supplemented, the "**Indenture**"), and will be sold to the underwriters (the "**Underwriters**") under the Underwriting Agreement dated January 3, 2023 (the "**Underwriting Agreement**") among the Company and J.P. Morgan Securities LLC, MUFG Securities Americas Inc., and U.S. Bancorp Investments, Inc., as representatives of the Underwriters.

In rendering this opinion, we have examined and relied on the Registration Statement, the Indenture, the form of the Senior Notes and such corporate records and other documents, and we have reviewed such matters of law, as we have deemed necessary or appropriate. We have also conducted such investigations of fact and law as we have deemed necessary or advisable for purposes of this letter. In rendering this opinion, we have, with your consent, relied upon oral and written representations of officers of the Company and certificates of officers of the Company and public officials with respect to the accuracy of the factual matters addressed in such representations and certificates. In addition, in rendering this opinion we have, with your consent, assumed (a) the authenticity of original documents and the genuineness of all signatures, (b) the conformity to the originals of all documents submitted to us as copies, (c) each natural person signing any document reviewed by us had the legal capacity to do so, (d) each person signing in a representative capacity any document reviewed by us had authority to sign in such capacity, (e) the truth, accuracy and completeness of the information, representations and warranties contained in the records, documents, instruments and certificates we have reviewed, (f) that all Senior Notes will be issued and sold in compliance with applicable federal and state securities laws, including applicable provisions of "blue sky" laws, and in the manner stated in the Registration Statement and the Prospectus Supplement, (g) each of the Senior Notes have been or will be duly authenticated and delivered by the Trustee against payment therefore in accordance with the provisions of the Transaction Documents (as defined below), and (h) the organizational documents of the Company, each as amended to the date hereof, will not have been amended from the date hereof in a manner that would affect the validity of the opinion rendered herein.

We have also assumed that the execution, delivery and performance of the Underwriting Agreement, Indenture and the Senior Notes (collectively, the "**Transaction Documents**") will not (a) violate, conflict with or result in a breach of, or require any consent under, the charters, bylaws or equivalent organizational documents of any party to such documents or the laws of the jurisdictions of organization or other applicable laws with respect to such parties, (b) violate any requirement or restriction imposed by any order, writ, judgment, injunction, decree, determination or award of any court or governmental body having jurisdiction over any party to such documents or any of their respective assets or (c) constitute a breach or violation of any agreement or instrument that is binding on any party to the Transaction Documents. We have also assumed that each party to the Transaction Documents other

------

than the Company (in the case of parties that are not natural persons) has been duly organized and is validly existing and in good standing under its jurisdiction of organization, that each such party (other than, with respect to the Senior Notes, the Company) has the legal capacity, power and authority (corporate or otherwise) to enter into, deliver and perform its obligations thereunder and that each of the Transaction Documents (other than, with respect to the Company, the Senior Notes) constitutes the valid and legally binding obligation of all such parties, enforceable against them in accordance with its terms. As to any facts material to the opinions expressed herein that we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of the Company and others.

Based on the foregoing, and subject to the qualifications and limitations stated herein, we are of the opinion that the Senior Notes will be the valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms.

The opinion set forth above is subject to the effects of (a) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting the enforcement of creditors' rights generally, (b) general equitable principles (including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing) regardless of whether considered in a proceeding in equity or at law, (c) applicable law and public policy with respect to rights to indemnity and contribution, (d) an implied covenant of good faith and fair dealing, (e) provisions of law that require that a judgment for money damages rendered by a court in the United States be expressed only in United States dollars, (f) limitations by any governmental authority that limit, delay or prohibit the making of payments outside the United States and (g) generally applicable laws that (i) provide for the enforcement of oral waivers or modifications where a material change of position in reliance thereon has occurred or provide that a course of performance may operate as a waiver, (ii) limit the availability of a remedy under certain circumstances where another remedy has been elected, (iii) limit the enforceability of provisions releasing, exculpating or exempting a party from, or requiring indemnification or contribution of a party for, liability for its own action or inaction, to the extent the action or inaction involves negligence, gross negligence, recklessness, willful misconduct or unlawful conduct, (iv) may, where less than all of a contract may be unenforceable, limit the enforceability of the balance of the contract to circumstances in which the unenforceable portion is not an essential part of the agreed exchange, (v) may limit the enforceability of provisions providing for compounded interest, imposing increased interest rates or late payment charges upon delinquency in payment or default or providing for liquidated damages or for premiums or penalties upon acceleration and (vi) limit the waiver of rights under usury laws. We express no opinion as to whether, or the extent to which, the laws of any particular jurisdiction apply to the subject matter hereof, including, without limitation, the enforceability of the governing law provision contained in the Senior Notes or the Indenture. Furthermore, the manner in which any particular issue relating to the opinions would be treated in any actual court case would depend in part on facts and circumstances particular to the case and would also depend on how the court involved chose to exercise the wide discretionary authority generally available to it. We express no opinion as to the effect of Section 210(p) of the Dodd-Frank Wall Street Reform and Consumer Protection Act.

This opinion is limited to the laws of the State Oklahoma. We express no opinion as to the laws of any other jurisdiction, including without limitation the federal laws of the United States. The opinions expressed herein are as of the date hereof only and are based on laws, orders, contract terms and provisions, and facts as of such date, and we disclaim any obligation to update this opinion letter after such date or to advise you of changes of facts stated or assumed herein or any subsequent changes in law.

We hereby consent to the filing of this opinion as Exhibit 5.01 to the Current Report on Form 8-K dated the date hereof and incorporated by reference into the Registration Statement and to the reference to us with respect to this opinion under the caption of "Legal Opinions" in the prospectus constituting a part of the Registration Statement. In giving such consent, we do not thereby admit that we are included in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission promulgated thereunder.

Very truly yours,
