SENIOR NOTES, SERIES DUE APRIL 15, 2028

PURCHASE AGREEMENT

April 13, 1998

To: Merrill Lynch, Pierce, Fenner & Smith Incorporated
CIBC Oppenheimer Corp.
Lehman Brothers Inc.

Ladies and Gentlemen:

Oklahoma Gas and Electric Company, an Oklahoma corporation (the "Company"), confirms its agreement with Merrill Lynch, Pierce, Fenner & Smith Incorporated, CIBC Oppenheimer Corp. and Lehman Brothers Inc. (collectively, the "Underwriters," which term includes any underwriter substituted as hereinafter provided in Section 11 hereof), with respect to the issue and sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the respective principal amounts set forth in Schedule A hereto of $100,000,000 aggregate principal amount of the Company's Senior Notes, Series due April 15, 2028 (the "Senior Notes"). The Senior Notes are to be issued pursuant to the Indenture dated as of October 1, 1995 between the Company and The Bank of New York, as successor trustee (the "Trustee"), as heretofore amended and supplemented and as amended and supplemented by Supplemental Indenture No. 3, dated as of April 1, 1998, creating the series in which the Senior Notes are to be issued. The term "Indenture," as used herein, means such Indenture dated as of October 1, 1995, as so amended and supplemented, and includes the Company Order (as defined in the Indenture), if any, establishing the form and terms of the Senior Notes pursuant to the Indenture.

The Company understands that the Underwriters propose to make a public offering of the Senior Notes as soon as they deem advisable after this Agreement has been executed and delivered and the Indenture has been qualified under the Trust Indenture Act of 1939, as amended (the "1939 Act").

The Company has filed with the Securities and Exchange Commission (the "Commission") a registration statement on Form S-3 (No. 333-46169) covering the registration of the Senior Notes under the Securities Act of 1933, as amended (the "1933 Act"), including the related preliminary prospectus or prospectuses. Promptly after execution and delivery of this Agreement, the Company will either
(i) prepare and file a prospectus in accordance with paragraph (b) of Rule 424 ("Rule 424(b)") of the rules and regulations of the Commission under the 1933 Act (the "1933 Act Regulations") or (ii) if the Company has elected to rely upon Rule 434 ("Rule 434") of the 1933 Act Regulations, prepare and file a term sheet (a "Term Sheet") in accordance with the provisions of Rule 434 and Rule 424(b). The information included in such prospectus or in such Term Sheet, as the case may be, that was omitted from such registration statement at the time it became effective is referred to as the "Offering Terms." Each prospectus used before such registration statement became effective, and any prospectus that omitted the Offering Terms, that was used after such effectiveness and prior to the execution and delivery of this Agreement, is herein called a "preliminary prospectus." Such registration statement, including the exhibits thereto, schedules thereto, if any, and the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, at the time it became effective and including the Offering Terms, is herein called the "Registration Statement." Any registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as the "Rule 462(b) Registration Statement," and after such filing the term "Registration Statement" shall include the Rule 462(b) Registration Statement. The final prospectus, including the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, in the form first furnished to the Underwriters for use in connection with the offering of the Senior Notes is herein called the "Prospectus." If Rule 434 is relied on, the term "Prospectus" shall refer to the preliminary prospectus dated February 26, 1998 together with the Term Sheet and all references in this Agreement to the date of the Prospectus shall mean the date of the Term Sheet. For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any Term Sheet or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

All references in this Agreement to financial statements and schedules and other information which is "contained," "included" or "stated" in the Registration Statement, any preliminary prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in the Registration Statement, any preliminary prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, any preliminary prospectus or the Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the "1934 Act") which is incorporated by reference in the Registration Statement, such preliminary prospectus or the Prospectus, as the case may be.

Neither the Prospectus nor any amendments or supplements thereto, at the time the Prospectus or any such amendment or supplement was issued and at the Closing Time, included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. If Rule 434 is used, the Company will comply with the requirements of Rule 434.

(ix) AUTHORIZATION OF AGREEMENT. This Agreement has been duly authorized, executed and delivered by the Company.

(x) AUTHORIZATION OF THE INDENTURE. The Indenture has been duly authorized by the Company and duly qualified under the 1939 Act and, when duly executed and delivered by the Company and the Trustee, will constitute a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting enforcement of creditors' rights generally and except as enforcement thereof is subject to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law).

(xi) AUTHORIZATION OF THE SENIOR NOTES. The Senior Notes have been duly authorized and, at the Closing Time, will have been duly executed by the Company and, when authenticated, issued and delivered in the manner provided for in the Indenture and delivered against payment of the purchase price therefor as provided in this Agreement, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting enforcement of creditors' rights generally and except as enforcement thereof is subject to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law), and will be in the form contemplated by, and entitled to the benefits provided by, the Indenture.

(xiii) ABSENCE OF DEFAULTS AND CONFLICTS. The Company is not in violation of its Restated Certificate of Incorporation or By-Laws or in default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which it is a party or by which it may be bound, or to which any of its property or assets is subject (collectively, "Agreements and Instruments") except for such defaults that would not result in a Material Adverse Effect; and the execution, delivery and performance of this Agreement, the Indenture and the Senior Notes, and the consummation of the transactions contemplated herein and in the Registration Statement (including the issuance and sale of the Senior Notes and the use of the proceeds from the sale of the Senior Notes as described in the Prospectus under the caption "Use of Proceeds") and compliance by the Company with its obligations hereunder and under the Indenture and the Senior Notes have been duly authorized by all necessary corporate action and do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to, the Agreements and Instruments (except for such conflicts, breaches, defaults or liens, charges or encumbrances that would not result in a Material Adverse Effect), nor will such action result in any violation of the provisions of the Restated Certificate of Incorporation or By-Laws of the Company or any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any of its assets, properties or operations. As used herein, a "Repayment Event" means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder's behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company, other than such events or conditions that are contemplated by the terms of this Agreement and the Indenture.

(xiv) ABSENCE OF PROCEEDINGS. Other than as disclosed in the Registration Statement, there is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending, or, to the knowledge of the Company, threatened, against or affecting the Company, which is required to be disclosed in the Registration Statement or which might reasonably be expected to result in a Material Adverse Effect, or which might reasonably be expected to materially and adversely affect its properties or assets or the consummation of the transactions contemplated in this Agreement or the performance by the Company of its obligations hereunder. The aggregate of all pending legal or governmental proceedings to which the Company is a party or of which any of its property or assets is the subject which are not described in the Registration Statement, including ordinary routine litigation incidental to the business, could not reasonably be expected to result in a Material Adverse Effect.

(xv) ACCURACY OF EXHIBITS. There are no contracts or documents which are required to be described in the Registration Statement, the Prospectus or the documents incorporated by reference therein or to be filed as exhibits thereto which have not been so described and filed as required.

(xvi) REGULATORY APPROVALS; ABSENCE OF FURTHER REQUIREMENTS. The
Corporation Commission of the State of Oklahoma (the "Oklahoma Commission") and the Arkansas Public Service Commission (the "Arkansas Commission") have, to the extent necessary, each duly authorized the issuance and sale of the Senior Notes on terms consistent with this Agreement. No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency is necessary or required for the performance by the Company of its obligations hereunder, in connection with the offering, issuance or sale of the Senior Notes hereunder or the consummation of the transactions contemplated by this Agreement or for the due execution, delivery or performance of the Indenture by the Company, except such as have been already obtained, including from the Oklahoma Commission and the Arkansas Commission.

(xvii) POSSESSION OF LICENSES AND PERMITS. The Company possesses such permits, licenses, approvals, consents and other authorizations issued by the appropriate federal, state, local or foreign regulatory agencies or bodies necessary to conduct in all material respects the business now operated by it and as described in the Registration Statement and Prospectus (collectively, "Governmental Licenses"); the Company is in compliance with the terms and conditions of all such Governmental Licenses, except where the failure so to comply would not, singly or in the aggregate, have a Material Adverse Effect; all of the Governmental Licenses are in full force and effect, except when the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not have a Material Adverse Effect; and the Company has not received any notice of proceedings relating to the revocation or modification of any such Governmental Licenses which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would result in a Material Adverse Effect.

(xviii) TITLE TO PROPERTY. The Company has good and sufficient title to all real property, principal plants and all other property owned by it and which is material to the Company's operations, in each case, free and clear of all mortgages, pledges, liens, security interests, claims, restrictions or encumbrances of any kind except such as (a) are described in the Prospectus or (b) do not, singly or in the aggregate, materially affect the value of such property and do not interfere with the use made and proposed to be made of such property by the Company; and all of the leases and subleases material to the business of the Company, and under which the Company holds properties described in the Prospectus, are in full force and effect, and the Company does not have notice of any material claim of any sort that has been asserted by anyone adverse to the rights of the Company under any of the leases or subleases mentioned above, or affecting or questioning the rights of the Company to the continued possession of the leased or subleased premises under any such lease or sublease.

(b) OFFICER'S CERTIFICATES. Any certificate signed by any officer of the Company or any of its subsidiaries delivered to any Underwriter or to counsel for the Underwriters shall be deemed a representation and warranty by the Company to each Underwriter as to the matters covered thereby.

The Company will promptly effect the filings necessary pursuant to Rule 424(b) and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus.

Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Offering Terms, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any

litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 7(d) below) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by Merrill Lynch, Pierce, Fenner & Smith Incorporated), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

PROVIDED, HOWEVER, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with the written information furnished to the Company by any Underwriter through Merrill Lynch, Pierce, Fenner & Smith Incorporated expressly for use in the Registration Statement (or any amendment thereto), including the Offering Terms, or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), which information is set forth on Schedule C hereto. The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to any Underwriter or to any controlling person of that Underwriter.

(b) INDEMNIFICATION OF COMPANY, DIRECTORS AND OFFICERS. Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Offering Terms, or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the written information furnished to the Company by such Underwriter through Merrill Lynch, Pierce, Fenner & Smith Incorporated expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the Prospectus (or any amendment or supplement thereto), which information is set forth on Schedule C hereto. The foregoing indemnity is in addition to any liability which any Underwriter may otherwise have to the Company or any such director, officer or controlling person.

(c) ACTIONS AGAINST PARTIES; NOTIFICATION. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability

which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 7(a) above, counsel to the indemnified parties shall be selected by Merrill Lynch, Pierce, Fenner & Smith Incorporated, and, in the case of parties indemnified pursuant to
Section 7(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; PROVIDED, HOWEVER, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 7 or Section 8 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability (including any obligation to pay any amounts in settlements) arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) SETTLEMENT WITHOUT CONSENT IF FAILURE TO REIMBURSE. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 8. CONTRIBUTION

If the indemnification provided for in Section 7 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Senior Notes pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Senior Notes pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Senior Notes pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus, or, if Rule 434 is used, the corresponding location on the Term Sheet, bear to the aggregate initial public offering price of the Senior Notes as set forth on such cover.

The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Senior Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters' respective obligations to contribute pursuant to this Section 8 are several in proportion to the principal amount of Senior Notes set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 9. REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE DELIVERY

All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Company, and shall survive delivery of the Senior Notes to the Underwriters.

SECTION 10. TERMINATION OF AGREEMENT

(a) TERMINATION; GENERAL. The Underwriter may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus, any loss sustained by the Company by strike, fire, flood, accident or other calamity of such character as to interfere materially with the conduct of the business and operations of the Company regardless of whether or not such loss shall have been insured, or any material adverse change in the condition, financial or otherwise, or in the earnings, results of operations, properties, business affairs or business prospects of the Company, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Underwriters, impracticable to market the Senior Notes or to enforce contracts for the sale of the Senior Notes, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or if trading generally on the American Stock Exchange or the New York Stock Exchange or in the Nasdaq National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, or (iv) if a banking moratorium has been declared by either Federal, New York or Oklahoma authorities.

(b) LIABILITIES. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 7, 8 and 9 shall survive such termination and remain in full force and effect.

SECTION 11. DEFAULT BY ONE OR MORE OF THE UNDERWRITERS

If one or more of the Underwriters fails at Closing Time to purchase the Senior Notes which it or they are obligated to purchase under this Agreement (the "Defaulted Senior Notes"), the remaining Underwriter or Underwriters will have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriter or underwriters, to purchase all, but not less than all, of the Defaulted Senior Notes in such

amounts as may be agreed upon and upon the terms herein set forth; if, however, the remaining Underwriter or Underwriters do not complete such arrangements within such 24-hour period, then:

(a) if the number of Defaulted Senior Notes does not exceed 10% of the aggregate principal amount of the Senior Notes to be purchased hereunder, each of the non-defaulting Underwriters will be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b) if the number of Defaulted Senior Notes exceeds 10% of the aggregate principal amount of the Senior Notes to be purchased hereunder, this Agreement will terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section will relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, either the remaining Underwriter or Underwriters or the Company will have the right to postpone Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term "Underwriter" includes any person substituted for an Underwriter under this
Section 11.
