Ladies and Gentlemen:

     Oklahoma Gas and Electric Company, an Oklahoma corporation (the "Company"),
confirms its agreement with Merrill Lynch, Pierce, Fenner & Smith Incorporated
("Merrill Lynch") and each of the other Underwriters named in Schedule A hereto
(collectively, the "Underwriters", which term includes any underwriter
substituted as hereinafter provided in Section 11 hereof), for whom Merrill
Lynch, Bear, Stearns & Co. Inc., Lehman Brothers Inc. and Morgan Stanley & Co.
Incorporated are acting as representatives (in such capacity, the
"Representatives"), 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 said Schedule A of $125,000,000
aggregate principal amount of the Company's Senior Notes, Series due July 15,
2027 (the "Senior Notes").  The Senior Notes are to be issued pursuant to the
Indenture dated as of October 1, 1995 between the Company and NationsBank, N.A.,
as trustee (the "Trustee"), as heretofore amended and supplemented and as
amended and supplemented by Supplemental Indenture No. 2, dated as of July 1,
1997, creating the series in which the Senior Notes are to be issued.  The term
"Indenture," as used herein, means such 

<PAGE>
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.

     Until such time as all of the first mortgage bonds of the Company (the
"First Mortgage Bonds") issued prior to the date of the Indenture have been
retired through payment or redemption, the Senior Notes will be secured as to
payment of principal and interest by one or more series of First Mortgage Bonds
issued, pledged and delivered by the Company to the Trustee.  Prior to the
issuance of the Senior Notes, the Company will deliver to the Trustee, as
security for the payment of principal and interest on the Senior Notes, a series
of First Mortgage Bonds (the "Bonds") in the same aggregate principal amount and
with the same stated rate or rates of interest (or interest calculated in the
same manner), payment dates, maturity dates, repayment provisions and redemption
provisions as the Senior Notes.  The Bonds will be issued by the Company under
its Trust Indenture dated February 1, 1945, between the Company and NationsBank,
N.A., as successor trustee (the "First Mortgage Trustee"), as heretofore amended
and supplemented and as to be further amended and supplemented by the
Supplemental Trust Indenture dated July 1, 1997 creating the Bonds.  The term
"First Mortgage Indenture," as used herein, means such Trust Indenture, dated
February 1, 1945, as so amended and supplemented. 

     Concurrently with the offering of the Senior Notes, the Company proposes to
issue and sell $125,000,000 of its 6.50% Senior Notes, Series due July 15, 2017
(the "Additional Senior Notes").  Prior to the issuance of the Additional Senior
Notes, the Company will deliver to the Trustee, as security for the payment of
principal and interest on the Senior Notes, a series of First Mortgage Bonds
(the "Additional Bonds") in the same aggregate principal amount and with the
same stated rate or rates of interest (or interest calculated in the same
manner), payment dates, maturity dates, repayment provisions and redemption
provisions as the Additional Senior Notes.  The Additional Bonds will also be
issued by the Company under the First Mortgage Indenture.  The sale of the
Senior Notes and the Additional Senior Notes are not contingent upon each other.

     The Company understands that the Underwriters propose to make a public
offering of the Senior Notes as soon as the Representatives deem advisable after
this Agreement has been executed and delivered and the Indenture and the First
Mortgage Indenture have 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. 333-02319) covering the
registration of the Senior Notes, the Bonds, the Additional Senior Notes and the
Additional Bonds 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 

                                       2
<PAGE>
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 and the Bonds is herein called the "Prospectus." 
 If Rule 434 is relied on, the term "Prospectus" shall refer to the 
preliminary prospectus dated July 15, 1997 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.

            (i)     COMPLIANCE WITH REGISTRATION REQUIREMENTS.  The Company
     meets the requirements for use of Form S-3 under the 1933 Act.  Each of the
     Registration Statement and any Rule 462(b) Registration Statement has
     become effective under the 1933 Act and no stop order suspending the
     effectiveness of the Registration Statement or any Rule 462(b) Registration
     Statement has been issued under the 1933 Act and no proceedings for that
     purpose have been instituted or are pending or, to the knowledge of the
     Company, are contemplated by the Commission, and any request on the part of
     the Commission for additional information has been complied with.

                                       3
<PAGE>

          At the respective times the Registration Statement, any Rule 462(b)
     Registration Statement and any post-effective amendments thereto became
     effective and at the Closing Time, the Registration Statement, the
     Rule 462(b) Registration Statement and any amendments and supplements
     thereto complied and will comply in all material respects with the
     requirements of the 1933 Act and the 1933 Act Regulations and the 1939 Act
     and the rules and regulations of the Commission under the 1939 Act (the
     "1939 Act Regulations"), and did not and will not contain an untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading.  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.  The
     representations and warranties in this subsection shall not apply to (A)
     that part of the Registration Statement which constitutes the Statements of
     Eligibility and Qualification (Form T-1) under the Trust Indenture Act (the
     "Statements of Eligibility") of the Trustee and the trustee for the First
     Mortgage Bonds, (B) information contained in the Registration Statement or
     the Prospectus relating to The Depository Trust Company and its book-entry
     system, or (C) statements in or omissions from the Registration Statement
     or Prospectus made in reliance upon and in conformity with the information
     furnished to the Company in writing by any Underwriter through Merrill
     Lynch expressly for use in the Registration Statement or Prospectus that is
     set forth on Schedule C hereto.

          Each preliminary prospectus and the prospectus filed as part of the
     Registration Statement as originally filed or as part of any amendment
     thereto, or filed pursuant to Rule 424 under the 1933 Act, complied when so
     filed in all material respects with the 1933 Act Regulations and each
     preliminary prospectus and the Prospectus delivered to the Underwriters for
     use in connection with this offering was identical to the electronically
     transmitted copies thereof filed with the Commission pursuant to EDGAR,
     except to the extent permitted by Regulation S-T.

           (ii)     INCORPORATED DOCUMENTS.  The documents incorporated or
     deemed to be incorporated by reference in the Registration Statement and
     the Prospectus, at the time they were or hereafter are filed with the
     Commission, complied and will comply in all material respects with the
     requirements of the 1933 Act and the 1933 Act Regulations or the 1934 Act
     and the rules and regulations of the Commission thereunder (the "1934 Act
     Regulations"), as applicable, and, when read together with the other
     information in the Prospectus, at the time the Registration Statement
     became effective, at the time the Prospectus was issued and at the Closing
     Time, did not and will not contain an untrue statement of a material fact
     or omit to state a material fact required to be stated therein or necessary
     to make the statements therein not misleading.

          (iii)     INDEPENDENT ACCOUNTANTS.  Arthur Andersen LLP, the
     accountants who examined the financial statements and supporting schedules
     included in the 

                                       4
<PAGE>

     Registration Statement, are independent public accountants as required by 
     the 1933 Act and the 1933 Act Regulations.

           (iv)     FINANCIAL STATEMENTS.  The financial statements included in
     the Registration Statement and the Prospectus, together with the related
     schedules and notes, present fairly the financial position of the Company
     and its consolidated subsidiaries at the dates indicated and the statement
     of operations, stockholders' equity and cash flows of the Company and its
     consolidated subsidiaries for the periods specified; said financial
     statements have been prepared in conformity with generally accepted
     accounting principles ("GAAP") applied on a consistent basis throughout the
     periods involved, except as otherwise stated in the notes thereto.  The
     supporting schedules, if any, included in the Registration Statement
     present fairly in accordance with GAAP the information required to be
     stated therein.  The selected financial information included in the
     Prospectus presents fairly the information shown therein and has been
     compiled on a basis consistent with that of the audited financial
     statements included in the Registration Statement.  The Company has no
     material contingent obligation which is not disclosed in the Prospectus.

            (v)     NO MATERIAL ADVERSE CHANGE.  Since the respective dates as
     of which information is given in the Registration Statement and the
     Prospectus, except as otherwise stated therein, (A) there has been no
     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 (a "Material Adverse Effect"), (B) there have been no transactions
     entered into by the Company, other than those in the ordinary course of
     business, which are material with respect to the Company, and (C) except
     for regular quarterly dividends on the Common Stock, par value $2.50 per
     share, of the Company in amounts consistent with past practice, and regular
     quarterly dividends on the Company's Preferred Stock, there has been no
     dividend or distribution of any kind declared, paid or made by the Company
     on any class of its capital stock.

           (vi)     GOOD STANDING OF THE COMPANY.  The Company has been duly
     organized and is validly existing as a corporation in good standing under
     the laws of the State of Oklahoma and has corporate power and authority to
     own, lease and operate its properties and to conduct its business as
     described in the Prospectus and to enter into and perform its obligations
     under this Agreement; and the Company is duly qualified as a foreign
     corporation to transact business and is in good standing in each other
     jurisdiction in which such qualification is required, whether by reason of
     the ownership or leasing of property or the conduct of business, except
     where the failure so to qualify or to be in good standing would not result
     in a Material Adverse Effect.

          (vii)     NO SUBSIDIARIES.  The Company has no subsidiaries.

         (viii)     CAPITALIZATION.  The authorized, issued and outstanding
     capital stock of the Company is as stated in the Prospectus.

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

            (x)     AUTHORIZATION OF THE INDENTURE AND THE FIRST MORTGAGE
     INDENTURE.  Each of the Indenture and the First Mortgage 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 or the
     First Mortgage Trustee, as applicable, 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.

          (xii)     AUTHORIZATION OF THE BONDS.  The Bonds 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 First Mortgage Indenture, 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 secured by the lien of and
     entitled to the benefits provided by, the First Mortgage Indenture.

         (xiii)     DESCRIPTION OF THE SENIOR NOTES, THE BONDS, THE INDENTURE
     AND THE FIRST MORTGAGE INDENTURE.  The Senior Notes, the Bonds, the
     Indenture and the First Mortgage Indenture will conform in all material
     respects to the respective statements relating thereto contained in the
     Prospectus and will be in substantially the respective forms filed or
     incorporated by reference, as the case may be, as exhibits to the
     Registration Statement.

          (xiv)     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 

                                       6
<PAGE>

     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, the First Mortgage Indenture, the Senior Notes
     and the Bonds 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, the First Mortgage Indenture, the Senior Notes and the Bonds
     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, the
     Indenture, the First Mortgage Indenture, the Senior Notes, Additional
     Senior Notes, the Bonds and the Additional Bonds.

           (xv)     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.

          (xvi)     ACCURACY OF EXHIBITS.  There are no contracts or documents
     which are required to be described in the Registration Statement, the
     Prospectus or the 

                                       7
<PAGE>

     documents incorporated by reference therein or to be filed as exhibits 
     thereto which have not been so described and filed as required. 

         (xvii)     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
     each duly authorized the issuance and sale of the Senior Notes and the
     issuance of the Bonds 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 and the issuance of the Bonds or the
     consummation of the transactions contemplated by this Agreement or for the
     due execution, delivery or performance of the Indenture or the First
     Mortgage Indenture by the Company, except such as have been already
     obtained, including from the Oklahoma Commission and the Arkansas
     Commission.

        (xviii)     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.

          (xix)     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 the Representatives or to

the Company to each Underwriter as to the matters covered thereby.

     SECTION 2.     SALE AND DELIVERY TO UNDERWRITERS; CLOSING

     (a)  SENIOR NOTES.  On the basis of the representations and warranties
herein contained and subject to the terms and conditions herein set forth, the
Company agrees to sell to each Underwriter, severally and not jointly, and each
Underwriter, severally and not jointly, agrees to purchase from the Company, at
the price set forth in Schedule B, the aggregate principal amount of Senior

     Payment shall be made to the Company by wire transfer of immediately
available funds to a bank account designated by the Company, against delivery to

that each Underwriter had authorized the Representatives, for its account, to
accept delivery of, receipt for, and make payment of the purchase price for, the
Senior Notes which it has agreed to purchase.  Merrill Lynch, individually and
not as representative of the Underwriters, may (but shall not be obligated to)

Underwriter whose funds have not been received by the Closing Time, but such
payment shall not relieve such Underwriter from its obligations hereunder.

     SECTION 3.     COVENANTS OF THE COMPANY

     The Company covenants with each Underwriter as follows:

     (a)  COMPLIANCE WITH SECURITIES REGULATIONS AND COMMISSION REQUESTS.  The
Company, subject to Section 3(b), will comply with the requirements of Rule 424
of the 1933 Act Regulations ("Rule 424") or Rule 434, as applicable, and will
notify the Representatives immediately, and confirm the notice in writing,
(i) of the effectiveness of any post-effective amendment to the Registration
Statement, or of the filing of any supplement to the Prospectus or any amended
Prospectus, (ii) of the receipt of any comments from the Commission, (iii) of
any request by the Commission for any amendment to the Registration Statement or
any amendment or supplement to the Prospectus or for additional information, and
(iv) of the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement or of any order preventing or
suspending the use of any preliminary prospectus, or of the suspension of the
qualification of the Senior Notes or the Bonds for offering or sale in any
jurisdiction, or of the initiation or threatening of any proceedings for any of
such purposes.  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.  The Company will make every reasonable
effort to prevent the issuance of any stop order and, if any stop order is
issued, to obtain the lifting thereof at the earliest possible moment.

     (b)  FILING OF AMENDMENTS.  The Company will give the Representatives
notice of its intention to file or prepare any amendment to the Registration
Statement (including any filing under Rule 462(b)), any Term Sheet or any
amendment, supplement or revision to either the prospectus included in the
Registration Statement at the time it became effective or to the Prospectus,
whether pursuant to the 1933 Act, the 1934 Act or otherwise, will furnish the
Representatives with copies of any such documents a reasonable amount of time
prior to such proposed filing or use, as the case may be, and will not file or
use any such document to which the Representatives or counsel for the
Underwriters reasonably objects.

     (c)  DELIVERY OF REGISTRATION STATEMENTS.  The Company has furnished or
will deliver to the Representatives and counsel for the Underwriters, without
charge, signed copies of the Registration Statement as originally filed and of
each amendment thereto (including exhibits filed therewith or incorporated by
reference therein and documents incorporated or deemed to be incorporated by
reference therein) and signed copies of all consents and certificates of
experts, in such number as the Representatives reasonably request, and will also
deliver to the Representatives, without charge, a conformed copy of the
Registration Statement as originally filed and of each amendment thereto
(without exhibits) for each of the Underwriters.  The copies of the Registration
Statement and each amendment thereto furnished to the Underwriters will be
identical to the electronically transmitted copies thereof filed with the
Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

     (d)  DELIVERY OF PROSPECTUSES.  The Company has delivered to each
Underwriter, without charge, as many copies of each preliminary prospectus as
such Underwriter reasonably requested, and the Company hereby consents to the
use of such copies for purposes permitted

                                       10

<PAGE>

by the 1933 Act.  The Company will furnish to each Underwriter, without 
charge, during the period when the Prospectus is required to be delivered 
under the 1933 Act or the 1934 Act, such number of copies of the Prospectus 
(as amended or supplemented) as such Underwriter may reasonably request.  The 
Prospectus and any amendments or supplements thereto furnished to the 
Underwriters will be identical to the electronically transmitted copies 
thereof filed with the Commission pursuant to EDGAR, except to the extent 
permitted by Regulation S-T.

     (e)  CONTINUED COMPLIANCE WITH SECURITIES LAWS.  The Company will comply
with the 1933 Act and the 1933 Act Regulations, the 1934 Act and the 1934 Act
Regulations and the 1939 Act and the 1939 Act Regulations so as to permit the
completion of the distribution of the Senior Notes as contemplated in this
Agreement and in the Prospectus.  If at any time when a prospectus is required
by the 1933 Act to be delivered in connection with sales of the Senior Notes,
any event occurs or condition exists as a result of which it is necessary, in
the opinion of counsel for the Underwriters or for the Company, to amend the
Registration Statement or amend or supplement the Prospectus in order that the
Prospectus will not include any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary in order to
make the statements therein not misleading in the light of the circumstances
existing at the time it is delivered to a purchaser, or if it is necessary, in
the opinion of such counsel, at any such time to amend the Registration
Statement or amend or supplement the Prospectus in order to comply with the
requirements of the 1933 Act or the 1933 Act Regulations, the Company will
promptly prepare and file with the Commission, subject to 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.

     (f)  RULE 158.  The Company will timely file such reports pursuant to the
1934 Act as are necessary in order to make generally available to its
securityholders as soon as practicable an earnings statement for the purposes
of, and to provide the benefits contemplated by, the last paragraph of
Section 11(a) of the 1933 Act.

     (g)  USE OF PROCEEDS.  The Company will use the net proceeds received by it
from the sale of the Senior Notes in the manner specified in the Prospectus
under "Use of Proceeds."

     (h)  REAL ESTATE MORTGAGE TAX.  The Company will use the amount deposited
by the Representatives with it pursuant to the last paragraph of Section 2
hereof to the extent necessary to pay for the account of the several
Underwriters, in the same proportion as the principal amount of Senior Notes to
be purchased by each of them bears to the total principal amount of Senior
Notes, any Oklahoma Real Estate Mortgage Tax required to be paid by them on the
Senior Notes and/or the Bonds.  Any amount not so applied by the Company before
the Closing Time shall be remitted in same day funds by the Company to the
Representatives for the account of the several Underwriters at the Closing Time.

     (i)  RESTRICTION ON SALE OF SECURITIES.  During the period beginning on the
date of this Agreement and continuing until the Closing Time, which period shall
in no event exceed 15 business days, the Company will not, without the prior
written consent of Merrill Lynch, in its sole discretion, directly or
indirectly, issue, sell, offer or contract to sell, grant any option for

            (i)     OPINION OF OKLAHOMA COUNSEL.  

               (A)  the Company is a legally existing corporation and is in good
          standing under the laws of the State of Oklahoma and has corporate
          power, right and authority to do business and to own property in the
          State of Oklahoma in the manner and as set forth in the Prospectus;

               (B)  the Indenture has been duly and validly executed and
          delivered by the Company, which has full power and authority to enter
          into and perform its obligations thereunder; and the Indenture
          constitutes the binding and enforceable agreement of the Company in
          accordance with its terms, except as enforcement of provisions of the
          Indenture may be limited by bankruptcy or other applicable laws
          affecting the enforcement of creditors' rights;

               (C)  the Senior Notes and the Bonds are in the form contemplated
          by the Indenture and the First Mortgage Indenture, respectively, have
          been duly and validly authorized by the Company, constitute valid and
          binding obligations of the Company and will be entitled to the
          benefits of the Indenture and the First Mortgage Indenture,
          respectively;

               (D)  while, except as otherwise stated in said opinion, such
          counsel are not passing upon and do not assume responsibility for and
          shall not be deemed to have independently verified the accuracy,
          completeness or fairness of the Registration Statement or the
          Prospectus, nothing has come to the attention of such counsel that
          would lead them to believe that the Registration Statement at the time
          it became effective contained an untrue statement of a material fact
          or omitted to state a material fact required to be stated therein or
          necessary to make the statements therein not misleading or that the
          Prospectus at the time it was filed pursuant to Rule 424 and/or
          Rule 434 under the 1933 Act or at the Closing Time contained an untrue
          statement of a material fact or omitted 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;

               (E)  the execution and delivery of this Agreement have been duly
          authorized by the necessary action on the part of the Company and this
          Agreement constitutes the valid and binding agreement of the Company
          except to the extent that the provisions for indemnities or
          contribution may be held to be unenforceable as against public policy;

                                       13

               (F)  except in localities where the Company has no franchises,
          which are relatively few and not of large population, or where the
          failure to have such franchises will not have a material adverse
          effect on the business or operations of the Company, the Company has
          sufficient authority under statutory provisions or by grant of
          franchises or permits by municipalities or counties to conduct its
          business in Oklahoma as presently conducted and as described in the
          Prospectus;

               (G)  such counsel does not know of any legal or governmental
          proceedings required to be described in the Prospectus which are not
          described as required, nor of any contracts or documents of a
          character required to be described in the Registration Statement or
          Prospectus or to be filed as exhibits to the Registration Statement
          which are not described and filed as required;

               (H)  the Indenture, the Senior Notes, the First Mortgage
          Indenture, the First Mortgage Bonds and the Bonds conform in all
          material respects to the statements concerning them in the Prospectus;

               (I)  all statements contained in the Registration Statement and
          Prospectus purporting to set forth the advice or the opinion of such
          counsel or to be based upon the opinion of such counsel correctly set
          forth the opinion of such counsel on such respective matters;

               (J)  the execution and delivery of this Agreement and the
          issuance of the Senior Notes and the Bonds, and compliance with the
          provisions thereof, under the circumstances contemplated hereby and
          thereby, do not and will not violate the Restated Certificate of
          Incorporation or By-Laws of the Company, or in any material respect
          conflict with or constitute on the part of the Company a breach of or
          default under any indenture, lease, mortgage, deed of trust, note,
          agreement or other instrument known to such counsel to which the
          Company is a party or any law, regulation, consent decree or
          administrative, arbitration or court order known to such counsel to
          which the Company is subject;

               (K)  the Oklahoma Commission has duly issued its order
          authorizing the issuance by the Company of the Senior Notes and the
          Bonds on terms consistent with this Agreement and, to the best of such
          counsel's knowledge, such order is still in force and effect; the
          issuance and sale of the Senior Notes to the Underwriters and the
          issuance of the Bonds to the Trustee are in conformity with the terms
          of such order; and no further approval, authorization, consent,
          certificate or order of any Oklahoma commission or regulatory
          authority is necessary with respect to the due authorization,
          execution and delivery of this Agreement, the due execution, delivery
          or performance of the Indenture and the First Mortgage Indenture by
          the Company or for the offering, issuance, sale or delivery of the
          Senior Notes to the Underwriters and the issuance or delivery of the
          Bonds by the Company to the Trustee as contemplated in this Agreement;

                                       14
<PAGE>

               (L)  to the best of such counsel's knowledge, the Company does
          not have any subsidiaries;

               (M)  the First Mortgage Indenture has been duly and validly
          executed and delivered by the Company, which has full power and
          authority to enter into and perform its obligations thereunder; and
          the First Mortgage Indenture constitutes the binding and enforceable
          agreement of the Company in accordance with its terms, except as
          enforcement of provisions of the First Mortgage Indenture may be
          limited by bankruptcy or other applicable laws affecting the
          enforcement of creditors' rights and except as provisions of the
          United States Bankruptcy Code may affect the validity of the lien
          thereof with respect to property acquired or proceeds realized by the
          Company within the 90-day period immediately preceding, or property
          acquired or proceeds realized by the Company after, the commencement
          of bankruptcy proceedings with respect to the Company;

               (N)  the Bonds have been duly and validly authorized by the
          Company, and constitute valid and binding obligations of the Company
          and, with like exception as noted in the foregoing subdivision (M),
          are entitled to the lien of and benefits provided by the First
          Mortgage Indenture;

               (O)  The First Mortgage Indenture is in proper form, conforming
          to the laws of the State of Oklahoma, to give and create the lien
          which it purports to create and has been and at the Closing Time is
          duly and properly recorded or filed in all places in Oklahoma
          necessary to effectuate the lien of the First Mortgage Indenture; and

               (P)  The Bonds are equally and ratably secured with all other
          First Mortgage Bonds outstanding under the First Mortgage Indenture by
          the First Mortgage Indenture subject to the provisions of the First
          Mortgage Indenture relating to any sinking fund or a similar fund for
          the benefit of the first mortgage bonds of any particular series. The
          First Mortgage Indenture constitutes a first mortgage lien, subject
          only to permissible encumbrances, as defined in the First Mortgage
          Indenture, on all of the property, real, personal, and mixed (except
          as hereinafter noted), in Oklahoma now owned by the Company. The First
          Mortgage Indenture also constitutes a first mortgage lien, subject to
          permissible encumbrances as defined in the First Mortgage Indenture,
          on all property, real, personal, and mixed (except as hereinafter
          noted), hereafter acquired by the Company in Oklahoma in conformity
          with the terms of the First Mortgage Indenture, except as the United
          States Bankruptcy Code may affect the validity of the lien of the
          First Mortgage Indenture on property acquired or proceeds realized by
          the Company within the 90-day period immediately preceding, or
          property acquired or proceeds realized by the Company after, the
          commencement of a case under such Code, except as to the prior lien of
          the First Mortgage Trustee under the First Mortgage Indenture in
          certain events specified therein and except as otherwise provided in
          the First Mortgage Indenture in case of consolidation or merger. 
          There are excepted from the lien of the First Mortgage 

                                       15

          (1) all shares of stock, bonds, notes, evidences of indebtedness

          deposited from time to time with the First Mortgage Trustee,

          (5) any oil, gas and other minerals under or on lands owned by

          course of business or for the purpose of consumption in the

          Company, and (7) certain properties specifically described in Schedule
          B to the First Mortgage Indenture not used or useful in the business
          of the Company.  The Company, except as to permissible encumbrances,
          as defined in the First Mortgage Indenture, has good and valid title
          to the real and fixed properties in Oklahoma and franchises from
          Oklahoma or federal authorities now owned by it (however, such opinion
          need not cover titles to rights-of-way or easements for transmission
          or distribution lines).

           (ii)     OPINION OF ARKANSAS COUNSEL.  

               (A)  the Company is duly qualified as a foreign corporation and

          preceding, or property acquired or proceeds realized by the Company

          accounts receivable, and choses in action other than such as may be or
          are required to be from time to time assigned to the First Mortgage
          Trustee, (4) motor vehicles, (5) any oil, gas and other minerals under
          or on lands owned by the Company, (6) goods, wares and merchandise,

          effect on the business or operations of the Company, the Company has
          sufficient authority under statutory provisions or by grant of

signed or reproduced copies of such letter for each of the other Underwriters
with respect to such matters related to the issuance and sale of the Senior
Notes as the Representatives may reasonably require, and the Company shall have
furnished to such counsel such documents as they request for the purpose of
enabling them to pass upon such matters.  In giving such opinion such counsel
may rely, as to all matters governed by the laws of jurisdictions other than the
law of the State of Illinois and the federal law of the United States, upon the
opinions of Oklahoma counsel, Arkansas counsel or other counsel satisfactory to
the Representatives.

     (e)  OFFICERS' CERTIFICATE.  At Closing Time, there shall not have been,
since the date hereof or since the respective dates as of which information is
given in the Prospectus, 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, and the Representatives shall have received a
certificate of the President or a Vice President of the Company and of the chief
financial or chief accounting officer of the Company, dated as of Closing Time,
to the effect that (i) there has been no such material adverse change, (ii) the
representations and warranties in this Agreement are true and correct with the
same force and effect as though expressly made at and as of Closing Time,
(iii) the Company has complied with all agreements and satisfied all conditions
on its part to be performed or satisfied at or prior to Closing Time, and
(iv) no stop order suspending the effectiveness of the Registration Statement
has been issued and no proceedings for that purpose have been instituted or are
pending or, to their knowledge, are contemplated by the Commission.

     (f)  ACCOUNTANT'S COMFORT LETTER.  At the time of the execution of this
Agreement, the Representatives shall have received from Arthur Andersen LLP a
letter, dated such date, in form and substance satisfactory to the
Representatives, together with signed or reproduced copies of such letter for
each of the other Underwriters containing statements and information of the type
ordinarily included in accountants' "comfort letters" to underwriters with
respect to the financial statements and certain financial information contained
in the Registration Statement and the Prospectus.

     (g)  BRING-DOWN COMFORT LETTER.  At Closing Time, the Representatives shall
have received from Arthur Andersen LLP a letter, dated as of Closing Time, to
the effect that they reaffirm the statements made in the letter furnished
pursuant to subsection (f) of this Section, except that the specified date
referred to shall be a date not more than three business days prior to Closing
Time.

     (h)  MAINTENANCE OF RATING.  At Closing Time, the Senior Notes shall be
rated at least A1 by Moody's Investor's Service Inc. and AA- by Standard &
Poor's Ratings Service, Inc.  Since the date of this Agreement, there shall not
have occurred a downgrading in the rating assigned to any of the Company's
securities by any "nationally recognized statistical rating organization," as
that term is defined by the Commission for purposes of Rule 436(g)(2) under the
1933 Act, and no such organization shall have publicly announced that it has
under surveillance or review its rating of the Senior Notes, the First Mortgage
Bonds or any of the Company's other securities.

                                       19
<PAGE>

     (i)  ADDITIONAL DOCUMENTS.  At Closing Time, counsel for the Underwriters
shall have been furnished with such documents and opinions as they may require
for the purpose of enabling them to pass upon the issuance and sale of the
Senior Notes and issuance and delivery of the Bonds as herein contemplated, or
in order to evidence the accuracy of any of the representations or warranties,
or the fulfillment of any of the conditions, herein contained; and all
proceedings taken by the Company in connection with the issuance and sale of the
Senior Notes and issuance and delivery of the Bonds as herein contemplated shall
be satisfactory in form and substance to the Representatives and counsel for the
Underwriters.

     (j)  TERMINATION OF AGREEMENT.  If any condition specified in this
Section shall not have been fulfilled when and as required to be fulfilled, this
Agreement may be terminated by the Representatives by notice to the Company at
any time at or prior to Closing Time, and such  termination shall be without
liability of any party to any other party except as provided in Section 4 and
except that Sections 1, 7, 8 and 9 shall survive any such termination and remain
in full force and effect.

     In giving the opinions contemplated by paragraphs (c) and (d) of this
Section 5, counsel may rely upon certificates of state officials as to the
Company's good standing and upon certificates of officers of the Company as to
matters of fact relevant to such opinions.  In giving such opinions, counsel may
assume (i) that the Senior Notes and the Bonds have been executed on behalf of
the Company by the manual or facsimile signatures of the President or a Vice
President and the Secretary or an Assistant Secretary of the Company and have
been manually authenticated by an authorized official of the Trustee and First
Mortgage Trustee, respectively, (ii) that the signatures on all documents
examined by them are genuine, and (iii) that the written information supplied by
the Representatives and the other Underwriters expressly for use in the
Registration Statement or the Prospectus is adequate.

     SECTION 6.     CONDITIONS OF COMPANY'S OBLIGATIONS

     The obligation of the Company to deliver the Senior Notes and the First
Mortgage Bonds upon payment therefor shall be subject to the following
conditions:

     At the Closing Time, (a) the orders of the Oklahoma Commission and the
Arkansas Commission referred to in paragraph (xvii) of Section 1(a) hereof shall
be in full force and effect substantially in the form in which originally
entered and (b) no stop order suspending the effectiveness of the Registration
Statement shall be in effect and no proceedings for that purpose shall then be
pending before, or threatened by, the Commission.

     In case any of the conditions specified above in this Section 6 shall not
have been fulfilled, this Agreement may be terminated by the Company by
delivering written notice of termination to the Representatives.  Any such
termination shall be without liability of any party to any other party except to
the extent provided in Section 4 hereof.

     SECTION 7.     INDEMNIFICATION

     (a)  INDEMNIFICATION OF UNDERWRITERS.  The Company agrees to indemnify and
hold harmless each Underwriter and each person, if any, who controls any
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act as follows:

            (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),
     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 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 

                                       21
<PAGE>

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 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, 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.  

                                       22
<PAGE>

     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.

                                       23
<PAGE>

     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 Representatives 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 Representatives, 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.

                                       24
<PAGE>

     (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 Representatives 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 Representatives 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 Representatives 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.

     SECTION 12.    NOTICES

     All notices and other communications hereunder shall be in writing and
shall be deemed to have been duly given if mailed or transmitted by any standard
form of telecommunication.  Notices to the Underwriters shall be directed to the

     SECTION 13.    PARTIES

     This Agreement shall each inure to the benefit of and be binding upon the
Underwriters and the Company and their respective successors.  Nothing expressed
or mentioned in this Agreement is intended or shall be construed to give any
person, firm or corporation, other than the Underwriters and the Company and
their respective successors and the controlling persons and officers and
directors referred to in Sections 7 and 8 and their heirs and legal
representatives, any legal or equitable right, remedy or claim under or in

all conditions and provisions hereof are intended to be for the sole and
exclusive benefit of the Underwriters and the Company and their respective
successors, and said controlling persons and officers and directors and their

                     SENIOR NOTES, SERIES DUE JULY 15, 2017


                               PURCHASE AGREEMENT

                                                                   July 15, 1997

c/o  Lehman Brothers Inc.

New York, New York  10285-0900


Ladies and Gentlemen:

     Oklahoma Gas and Electric Company, an Oklahoma corporation (the "Company"),
confirms its agreement with Lehman Brothers Inc. ("Lehman Brothers") and each of
the other Underwriters named in Schedule A hereto (collectively, the
"Underwriters", which term includes any underwriter substituted as hereinafter
provided in Section 11 hereof), for whom Lehman Brothers, Bear, Stearns & Co.
Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated and Morgan Stanley &
Co. Incorporated are acting as representatives (in such capacity, the
"Representatives"), 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 said Schedule A of $125,000,000
aggregate principal amount of the Company's Senior Notes, Series due July 15,
2017 (the "Senior Notes").  The Senior Notes are to be issued pursuant to the
Indenture dated as of October 1, 1995 between the Company and NationsBank, N.A.,
as trustee (the "Trustee"), as heretofore amended and supplemented and as
amended and supplemented by Supplemental Indenture No. 2, dated as of July 1,
1997, 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,

<PAGE>

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.

     Until such time as all of the first mortgage bonds of the Company (the
"First Mortgage Bonds") issued prior to the date of the Indenture have been
retired through payment or redemption, the Senior Notes will be secured as to
payment of principal and interest by one or more series of First Mortgage Bonds
issued, pledged and delivered by the Company to the Trustee.  Prior to the
issuance of the Senior Notes, the Company will deliver to the Trustee, as
security for the payment of principal and interest on the Senior Notes, a series
of First Mortgage Bonds (the "Bonds") in the same aggregate principal amount and
with the same stated rate or rates of interest (or interest calculated in the
same manner), payment dates, maturity dates, repayment provisions and redemption
provisions as the Senior Notes.  The Bonds will be issued by the Company under
its Trust Indenture dated February 1, 1945, between the Company and NationsBank,
N.A., as successor trustee (the "First Mortgage Trustee"), as heretofore amended
and supplemented and as to be further amended and supplemented by the
Supplemental Trust Indenture dated July 1, 1997 creating the Bonds.  The term
"First Mortgage Indenture," as used herein, means such Trust Indenture, dated
February 1, 1945, as so amended and supplemented. 

     Concurrently with the offering of the Senior Notes, the Company proposes to
issue and sell $125,000,000 of its 6.65% Senior Notes, Series due July 15, 2027
(the "Additional Senior Notes").  Prior to the issuance of the Additional Senior
Notes, the Company will deliver to the Trustee, as security for the payment of
principal and interest on the Senior Notes, a series of First Mortgage Bonds
(the "Additional Bonds") in the same aggregate principal amount and with the
same stated rate or rates of interest (or interest calculated in the same
manner), payment dates, maturity dates, repayment provisions and redemption
provisions as the Additional Senior Notes.  The Additional Bonds will also be
issued by the Company under the First Mortgage Indenture.  The sale of the
Senior Notes and the Additional Senior Notes are not contingent upon each other.

     The Company understands that the Underwriters propose to make a public
offering of the Senior Notes as soon as the Representatives deem advisable after
this Agreement has been executed and delivered and the Indenture and the First
Mortgage Indenture have 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. 333-02319) covering the
registration of the Senior Notes, the Bonds, the Additional Senior Notes and the
Additional Bonds 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

                                     2

<PAGE>

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 and the Bonds is herein called
the "Prospectus."  If Rule 434 is relied on, the term "Prospectus" shall refer
to the preliminary prospectus dated July 15, 1997 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.

     SECTION 1.     REPRESENTATIONS AND WARRANTIES

     (a)  REPRESENTATIONS AND WARRANTIES BY THE COMPANY.  The Company represents
and warrants to each Underwriter as of the date hereof and as of the Closing
Time referred to in Section 2(b) hereof, and agrees with each Underwriter, as
follows:

            (i)     COMPLIANCE WITH REGISTRATION REQUIREMENTS.  The Company
     meets the requirements for use of Form S-3 under the 1933 Act.  Each of the
     Registration Statement and any Rule 462(b) Registration Statement has
     become effective under the 1933 Act and no stop order suspending the
     effectiveness of the Registration Statement or any Rule 462(b) Registration
     Statement has been issued under the 1933 Act and no proceedings for that
     purpose have been instituted or are pending or, to the knowledge of the
     Company, are contemplated by the Commission, and any request on the part of
     the Commission for additional information has been complied with.

                                     3

<PAGE>

          At the respective times the Registration Statement, any Rule 462(b)
     Registration Statement and any post-effective amendments thereto became
     effective and at the Closing Time, the Registration Statement, the
     Rule 462(b) Registration Statement and any amendments and supplements
     thereto complied and will comply in all material respects with the
     requirements of the 1933 Act and the 1933 Act Regulations and the 1939 Act
     and the rules and regulations of the Commission under the 1939 Act (the
     "1939 Act Regulations"), and did not and will not contain an untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading.  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.  The
     representations and warranties in this subsection shall not apply to (A)
     that part of the Registration Statement which constitutes the Statements of
     Eligibility and Qualification (Form T-1) under the Trust Indenture Act (the
     "Statements of Eligibility") of the Trustee and the trustee for the First
     Mortgage Bonds, (B) information contained in the Registration Statement or
     the Prospectus relating to The Depository Trust Company and its book-entry
     system, or (C) statements in or omissions from the Registration Statement
     or Prospectus made in reliance upon and in conformity with the information
     furnished to the Company in writing by any Underwriter through Lehman
     Brothers expressly for use in the Registration Statement or Prospectus that
     is set forth on Schedule C hereto.

          Each preliminary prospectus and the prospectus filed as part of the
     Registration Statement as originally filed or as part of any amendment
     thereto, or filed pursuant to Rule 424 under the 1933 Act, complied when so
     filed in all material respects with the 1933 Act Regulations and each
     preliminary prospectus and the Prospectus delivered to the Underwriters for
     use in connection with this offering was identical to the electronically
     transmitted copies thereof filed with the Commission pursuant to EDGAR,
     except to the extent permitted by Regulation S-T.

           (ii)     INCORPORATED DOCUMENTS.  The documents incorporated or
     deemed to be incorporated by reference in the Registration Statement and
     the Prospectus, at the time they were or hereafter are filed with the
     Commission, complied and will comply in all material respects with the
     requirements of the 1933 Act and the 1933 Act Regulations or the 1934 Act
     and the rules and regulations of the Commission thereunder (the "1934 Act
     Regulations"), as applicable, and, when read together with the other
     information in the Prospectus, at the time the Registration Statement
     became effective, at the time the Prospectus was issued and at the Closing
     Time, did not and will not contain an untrue statement of a material fact
     or omit to state a material fact required to be stated therein or necessary
     to make the statements therein not misleading.

          (iii)     INDEPENDENT ACCOUNTANTS.  Arthur Andersen LLP, the
     accountants who examined the financial statements and supporting schedules

                                     4

<PAGE>

     included in the Registration Statement, are independent public accountants
     as required by the 1933 Act and the 1933 Act Regulations.

           (iv)     FINANCIAL STATEMENTS.  The financial statements included in
     the Registration Statement and the Prospectus, together with the related
     schedules and notes, present fairly the financial position of the Company
     and its consolidated subsidiaries at the dates indicated and the statement
     of operations, stockholders' equity and cash flows of the Company and its
     consolidated subsidiaries for the periods specified; said financial
     statements have been prepared in conformity with generally accepted
     accounting principles ("GAAP") applied on a consistent basis throughout the
     periods involved, except as otherwise stated in the notes thereto.  The
     supporting schedules, if any, included in the Registration Statement
     present fairly in accordance with GAAP the information required to be
     stated therein.  The selected financial information included in the
     Prospectus presents fairly the information shown therein and has been
     compiled on a basis consistent with that of the audited financial
     statements included in the Registration Statement.  The Company has no
     material contingent obligation which is not disclosed in the Prospectus.

            (v)     NO MATERIAL ADVERSE CHANGE.  Since the respective dates as
     of which information is given in the Registration Statement and the
     Prospectus, except as otherwise stated therein, (A) there has been no
     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 (a "Material Adverse Effect"), (B) there have been no transactions
     entered into by the Company, other than those in the ordinary course of
     business, which are material with respect to the Company, and (C) except
     for regular quarterly dividends on the Common Stock, par value $2.50 per
     share, of the Company in amounts consistent with past practice, and regular

     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

          (xii)     AUTHORIZATION OF THE BONDS.  The Bonds have been duly
     authorized and, at the Closing Time, will have been duly executed by the

<PAGE>

     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, the First Mortgage Indenture, the Senior Notes
     and the Bonds 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, the First Mortgage Indenture, the Senior Notes and the Bonds
     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, the
     Indenture, the First Mortgage Indenture, the Senior Notes, Additional
     Senior Notes, the Bonds and the Additional Bonds.

           (xv)     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.

          (xvi)     ACCURACY OF EXHIBITS.  There are no contracts or documents
     which are required to be described in the Registration Statement, the

                                     7

<PAGE>

     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. 

         (xvii)     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
     each duly authorized the issuance and sale of the Senior Notes and the
     issuance of the Bonds 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 and the issuance of the Bonds or the
     consummation of the transactions contemplated by this Agreement or for the
     due execution, delivery or performance of the Indenture or the First
     Mortgage Indenture by the Company, except such as have been already
     obtained, including from the Oklahoma Commission and the Arkansas
     Commission.

        (xviii)     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.

          (xix)     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 the Representatives 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.

     SECTION 2.     SALE AND DELIVERY TO UNDERWRITERS; CLOSING

     (a)  SENIOR NOTES.  On the basis of the representations and warranties
herein contained and subject to the terms and conditions herein set forth, the
Company agrees to sell to each Underwriter, severally and not jointly, and each
Underwriter, severally and not jointly, agrees to purchase from the Company, at
the price set forth in Schedule B, the aggregate principal amount of Senior
Notes set forth in Schedule A opposite the name of such Underwriter, plus any
additional principal amount of Senior Notes which such Underwriter may become
obligated to purchase pursuant to the provisions of Section 11 hereof.

certificates for, the Senior Notes shall be made at the offices of Gardner,
Carton & Douglas, Quaker Tower, Suite 3100, 321 North Clark Street, Chicago,
Illinois  60610-4795, or at such other place as shall be agreed upon by the
Representatives and the Company, at 9:00 A.M. (Central time) on the fourth
business day after the date hereof (unless postponed in accordance with the

after such date as shall be agreed upon by the Representatives and the Company
(such time and date of payment and delivery being herein called "Closing Time").

     Payment shall be made to the Company by wire transfer of immediately
available funds to a bank account designated by the Company, against delivery to
the Representatives for the respective accounts of the Underwriters of

that each Underwriter had authorized the Representatives, for its account, to
accept delivery of, receipt for, and make payment of the purchase price for, the
Senior Notes which it has agreed to purchase.  Lehman Brothers, individually and
not as representative of the Underwriters, may (but shall not be obligated to)
make payment of the purchase price for the Senior Notes to be purchased by any
Underwriter whose funds have not been received by the Closing Time, but such
payment shall not relieve such Underwriter from its obligations hereunder.

shall be in the amount of $125,000,000 and registered in the name of Cede & Co.,

Estate Mortgage Tax.  It is understood that such payment shall not constitute
partial or full payment for the Senior Notes, but shall be applied solely in
accordance with Section 3(h) hereof.

                                     9

     SECTION 3.     COVENANTS OF THE COMPANY

     The Company covenants with each Underwriter as follows:

     (a)  COMPLIANCE WITH SECURITIES REGULATIONS AND COMMISSION REQUESTS.  The
Company, subject to Section 3(b), will comply with the requirements of Rule 424
of the 1933 Act Regulations ("Rule 424") or Rule 434, as applicable, and will
notify the Representatives immediately, and confirm the notice in writing,
(i) of the effectiveness of any post-effective amendment to the Registration
Statement, or of the filing of any supplement to the Prospectus or any amended
Prospectus, (ii) of the receipt of any comments from the Commission, (iii) of
any request by the Commission for any amendment to the Registration Statement or
any amendment or supplement to the Prospectus or for additional information, and
(iv) of the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement or of any order preventing or
suspending the use of any preliminary prospectus, or of the suspension of the
qualification of the Senior Notes or the Bonds for offering or sale in any
jurisdiction, or of the initiation or threatening of any proceedings for any of
such purposes.  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.  The Company will make every reasonable
effort to prevent the issuance of any stop order and, if any stop order is
issued, to obtain the lifting thereof at the earliest possible moment.

     (b)  FILING OF AMENDMENTS.  The Company will give the Representatives
notice of its intention to file or prepare any amendment to the Registration
Statement (including any filing under Rule 462(b)), any Term Sheet or any
amendment, supplement or revision to either the prospectus included in the
Registration Statement at the time it became effective or to the Prospectus,
whether pursuant to the 1933 Act, the 1934 Act or otherwise, will furnish the
Representatives with copies of any such documents a reasonable amount of time
prior to such proposed filing or use, as the case may be, and will not file or
use any such document to which the Representatives or counsel for the
Underwriters reasonably objects.

     (c)  DELIVERY OF REGISTRATION STATEMENTS.  The Company has furnished or
will deliver to the Representatives and counsel for the Underwriters, without
charge, signed copies of the Registration Statement as originally filed and of
each amendment thereto (including exhibits filed therewith or incorporated by
reference therein and documents incorporated or deemed to be incorporated by
reference therein) and signed copies of all consents and certificates of
experts, in such number as the Representatives reasonably request, and will also
deliver to the Representatives, without charge, a conformed copy of the
Registration Statement as originally filed and of each amendment thereto
(without exhibits) for each of the Underwriters.  The copies of the Registration
Statement and each amendment thereto furnished to the Underwriters will be
identical to the electronically transmitted copies thereof filed with the
Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

     (d)  DELIVERY OF PROSPECTUSES.  The Company has delivered to each
Underwriter, without charge, as many copies of each preliminary prospectus as
such Underwriter reasonably requested, and the Company hereby consents to the

                                     10

<PAGE>

use of such copies for purposes permitted by the 1933 Act.  The Company will
furnish to each Underwriter, without charge, during the period when the
Prospectus is required to be delivered under the 1933 Act or the 1934 Act, such
number of copies of the Prospectus (as amended or supplemented) as such
Underwriter may reasonably request.  The Prospectus and any amendments or
supplements thereto furnished to the Underwriters will be identical to the
electronically transmitted copies thereof filed with the Commission pursuant to
EDGAR, except to the extent permitted by Regulation S-T.

     (e)  CONTINUED COMPLIANCE WITH SECURITIES LAWS.  The Company will comply
with the 1933 Act and the 1933 Act Regulations, the 1934 Act and the 1934 Act
Regulations and the 1939 Act and the 1939 Act Regulations so as to permit the
completion of the distribution of the Senior Notes as contemplated in this
Agreement and in the Prospectus.  If at any time when a prospectus is required
by the 1933 Act to be delivered in connection with sales of the Senior Notes,
any event occurs or condition exists as a result of which it is necessary, in
the opinion of counsel for the Underwriters or for the Company, to amend the
Registration Statement or amend or supplement the Prospectus in order that the
Prospectus will not include any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary in order to
make the statements therein not misleading in the light of the circumstances
existing at the time it is delivered to a purchaser, or if it is necessary, in
the opinion of such counsel, at any such time to amend the Registration
Statement or amend or supplement the Prospectus in order to comply with the
requirements of the 1933 Act or the 1933 Act Regulations, the Company will
promptly prepare and file with the Commission, subject to 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.

     (f)  RULE 158.  The Company will timely file such reports pursuant to the
1934 Act as are necessary in order to make generally available to its
securityholders as soon as practicable an earnings statement for the purposes
of, and to provide the benefits contemplated by, the last paragraph of
Section 11(a) of the 1933 Act.

     (g)  USE OF PROCEEDS.  The Company will use the net proceeds received by it
from the sale of the Senior Notes in the manner specified in the Prospectus
under "Use of Proceeds."

     (h)  REAL ESTATE MORTGAGE TAX.  The Company will use the amount deposited
by the Representatives with it pursuant to the last paragraph of Section 2
hereof to the extent necessary to pay for the account of the several
Underwriters, in the same proportion as the principal amount of Senior Notes to
be purchased by each of them bears to the total principal amount of Senior
Notes, any Oklahoma Real Estate Mortgage Tax required to be paid by them on the
Senior Notes and/or the Bonds.  Any amount not so applied by the Company before
the Closing Time shall be remitted in same day funds by the Company to the
Representatives for the account of the several Underwriters at the Closing Time.

     (i)  RESTRICTION ON SALE OF SECURITIES.  During the period beginning on the
date of this Agreement and continuing until the Closing Time, which period shall
in no event exceed 15 business days, the Company will not, without the prior
written consent of Lehman Brothers, in its sole discretion, directly or

                                     11

<PAGE>

indirectly, issue, sell, offer or contract to sell, grant any option for the
sale of, or otherwise transfer or dispose of, any debt securities of the Company
which mature more than one year after the Closing Time and which are
substantially similar to the Senior Notes.

     SECTION 4.     PAYMENT OF EXPENSES

     (a)  EXPENSES.  Whether or not the transactions contemplated hereunder are
consummated or this Agreement is terminated, the Company will pay all expenses
incident to the performance of its obligations under this Agreement, including
(i) the preparation, printing and filing of the Registration Statement
(including financial statements and exhibits) as originally filed and of each
amendment thereto, (ii) the preparation, printing and delivery to the
Underwriters of this Agreement, any Agreement among Underwriters, the Indenture,
the First Mortgage Indenture and such other documents as may be required in
connection with the offering, purchase, sale, issuance or delivery of the Senior
Notes and the Bonds, (iii) all costs, taxes (other than any Oklahoma Real Estate
Mortgage Tax) and expenses incident to the preparation, issuance and delivery of
the Senior Notes to the Underwriters and the Bonds to the Trustee, (iv) the fees
and disbursements of the Company's counsel, accountants and other advisors,
(v) the printing and delivery to the Underwriters of copies of each preliminary
prospectus, any Term Sheets and of the Prospectus and any amendments or
supplements thereto, (vi) the fees and expenses of the Trustee and the First
Mortgage Trustee, including the fees and disbursements of counsel for the
Trustee and the First Mortgage Trustee in connection with the Indenture, the
First Mortgage Indenture, the Senior Notes and the Bonds, and (vii) any fees
payable in connection with the rating of the Senior Notes and the Bonds.

     (b)  TERMINATION OF AGREEMENT.  If this Agreement is terminated by the
Representatives in accordance with the provisions of Section 5, Section 6 or
Section 10(a)(i) hereof, the Company shall reimburse the Underwriters for all of
their out-of-pocket expenses, including the reasonable fees and disbursements of
counsel for the Underwriters.

     SECTION 5.     CONDITIONS OF UNDERWRITERS' OBLIGATIONS

     The obligations of the several Underwriters hereunder are subject to the
accuracy of the representations and warranties of the Company contained in
Section 1 hereof and in certificates of any officer of the Company delivered

covenants and other obligations hereunder and to the following further
conditions:

     (a)  EFFECTIVENESS OF REGISTRATION STATEMENT; FILING OF PROSPECTUS.  The
Registration Statement, including any Rule 462(b) Registration Statement, has
become effective and at Closing Time no stop order suspending the effectiveness
of the Registration Statement shall have been issued under the 1933 Act or
proceedings therefor initiated or threatened by the Commission, and any request
on the part of the Commission for additional information shall have been
complied with to the reasonable satisfaction of counsel to the Underwriters.  A
prospectus containing the Offering Terms shall have been filed with the
Commission in accordance with Rule 424(b) or, if the Company has elected to rely
upon Rule 434, a Term Sheet shall have been filed with the Commission in

                                     12

<PAGE>

     (b)  SECURITY FOR SENIOR NOTES.  The Company shall have issued and
delivered to the Trustee the Bonds, as security for, among other things, the
Senior Notes.

     (c)  OPINIONS OF COUNSEL FOR COMPANY.  At Closing Time, the Representatives
shall have received the favorable opinions, dated as of Closing Time, of
Gardner, Carton & Douglas, Rainey, Ross, Rice & Binns ("Oklahoma counsel) and
Chisenhall, Nestrud & Julian, P.A. ("Arkansas counsel"), each counsel for the
Company, in form and substance satisfactory to counsel for the Underwriters,
together with signed or reproduced copies of such letter for each of the other
Underwriters to the effect set forth below and to such further effect as counsel
to the Underwriters may reasonably request.

            (i)     OPINION OF OKLAHOMA COUNSEL.  

               (A)  the Company is a legally existing corporation and is in good
          standing under the laws of the State of Oklahoma and has corporate
          power, right and authority to do business and to own property in the
          State of Oklahoma in the manner and as set forth in the Prospectus;

               (B)  the Indenture has been duly and validly executed and
          delivered by the Company, which has full power and authority to enter
          into and perform its obligations thereunder; and the Indenture
          constitutes the binding and enforceable agreement of the Company in
          accordance with its terms, except as enforcement of provisions of the
          Indenture may be limited by bankruptcy or other applicable laws
          affecting the enforcement of creditors' rights;

               (C)  the Senior Notes and the Bonds are in the form contemplated
          by the Indenture and the First Mortgage Indenture, respectively, have
          been duly and validly authorized by the Company, constitute valid and
          binding obligations of the Company and will be entitled to the
          benefits of the Indenture and the First Mortgage Indenture,
          respectively;

               (D)  while, except as otherwise stated in said opinion, such
          counsel are not passing upon and do not assume responsibility for and
          shall not be deemed to have independently verified the accuracy,
          completeness or fairness of the Registration Statement or the
          Prospectus, nothing has come to the attention of such counsel that
          would lead them to believe that the Registration Statement at the time
          it became effective contained an untrue statement of a material fact
          or omitted to state a material fact required to be stated therein or
          necessary to make the statements therein not misleading or that the
          Prospectus at the time it was filed pursuant to Rule 424 and/or
          Rule 434 under the 1933 Act or at the Closing Time contained an untrue
          statement of a material fact or omitted 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;

               (E)  the execution and delivery of this Agreement have been duly
          authorized by the necessary action on the part of the Company and this
          Agreement constitutes the valid and binding agreement of the Company

                                     13

          sufficient authority under statutory provisions or by grant of
          franchises or permits by municipalities or counties to conduct its

          proceedings required to be described in the Prospectus which are not
          described as required, nor of any contracts or documents of a

          issuance of the Senior Notes and the Bonds, and compliance with the

          Incorporation or By-Laws of the Company, or in any material respect
          conflict with or constitute on the part of the Company a breach of or
          default under any indenture, lease, mortgage, deed of trust, note,

          certificate or order of any Oklahoma commission or regulatory
          authority is necessary with respect to the due authorization,
          execution and delivery of this Agreement, the due execution, delivery
          or performance of the Indenture and the First Mortgage Indenture by
          the Company or for the offering, issuance, sale or delivery of the

          executed and delivered by the Company, which has full power and
          authority to enter into and perform its obligations thereunder; and

          agreement of the Company in accordance with its terms, except as
          enforcement of provisions of the First Mortgage Indenture may be
          limited by bankruptcy or other applicable laws affecting the
          enforcement of creditors' rights and except as provisions of the
          United States Bankruptcy Code may affect the validity of the lien
          thereof with respect to property acquired or proceeds realized by the
          Company within the 90-day period immediately preceding, or property
          acquired or proceeds realized by the Company after, the commencement
          of bankruptcy proceedings with respect to the Company;

               (N)  the Bonds have been duly and validly authorized by the

          which it purports to create and has been and at the Closing Time is
          duly and properly recorded or filed in all places in Oklahoma
          necessary to effectuate the lien of the First Mortgage Indenture; and

          the benefit of the first mortgage bonds of any particular series. The

          only to permissible encumbrances, as defined in the First Mortgage
          Indenture, on all of the property, real, personal, and mixed (except

          permissible encumbrances as defined in the First Mortgage Indenture,
          on all property, real, personal, and mixed (except as hereinafter
          noted), hereafter acquired by the Company in Oklahoma in conformity

          States Bankruptcy Code may affect the validity of the lien of the
          First Mortgage Indenture on property acquired or proceeds realized by
          the Company within the 90-day period immediately preceding, or
          property acquired or proceeds realized by the Company after, the
          commencement of a case under such Code, except as to the prior lien of
          the First Mortgage Trustee under the First Mortgage Indenture in
          certain events specified therein and except as otherwise provided in
          the First Mortgage Indenture in case of consolidation or merger. 
          There are excepted from the lien of the First Mortgage Indenture, as

          Company, and (7) certain properties specifically described in Schedule
          B to the First Mortgage Indenture not used or useful in the business
          of the Company.  The Company, except as to permissible encumbrances,
          as defined in the First Mortgage Indenture, has good and valid title
          to the real and fixed properties in Oklahoma and franchises from
          Oklahoma or federal authorities now owned by it (however, such opinion
          need not cover titles to rights-of-way or easements for transmission
          or distribution lines).

          mortgage lien, subject to permissible encumbrances as defined in the

          preceding, or property acquired or proceeds realized by the Company

          cover titles to rights-of-way or easements for transmission or
          distribution lines);

               (D)  except in localities where the Company has no franchises,

          failure to have such franchises will not have a material adverse
          effect on the business or operations of the Company, the Company has
          sufficient authority under statutory provisions or by grant of

          contemplated in this Agreement; and

     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 Lehman
     Brothers), 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 Lehman Brothers 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,

                                     21

<PAGE>

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 Lehman Brothers 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 Lehman Brothers, 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.  

                                     22

     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.

                                     23

<PAGE>

     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 Representatives 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 Representatives, 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.

                                     24

<PAGE>

     (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 Representatives 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 Representatives 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 Representatives 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.

     SECTION 12.    NOTICES

     All notices and other communications hereunder shall be in writing and
shall be deemed to have been duly given if mailed or transmitted by any standard
form of telecommunication.  Notices to the Underwriters shall be directed to the

     This Agreement shall each inure to the benefit of and be binding upon the
Underwriters and the Company and their respective successors.  Nothing expressed

person, firm or corporation, other than the Underwriters and the Company and
their respective successors and the controlling persons and officers and
directors referred to in Sections 7 and 8 and their heirs and legal
representatives, any legal or equitable right, remedy or claim under or in

Debt, the Company will promptly execute, at its expense, any instruments 
necessary to so equally and ratably secure such series of Notes and deliver 
the same to the Trustee along with:

          (1)  An Officers' Certificate stating that the covenant of the

               Company in the performance of such covenant comply with the
               requirements of such covenant.

     In the event that the Company shall hereafter secure outstanding Senior
Notes due 2027 or outstanding Senior Notes due 2017 equally and ratably with any
other obligation or indebtedness (including other Notes) pursuant to the
provisions of this Section 4.01, the Trustee is hereby authorized to enter into
an indenture or agreement supplemental hereto and to take such action, if any,
as it may deem advisable to enable it to enforce effectively the rights of the
holders of such series of Notes so secured, equally and ratably with such other
obligation and indebtedness.

Notes due 2027 or Senior Notes due 2017 are outstanding, the Company will not
enter into any Sale and Lease-Back Transaction with respect to any Operating
Property and will not permit to remain in effect any Sale and Lease-Back
Transaction entered into on or prior to the Release Date with respect to any

of the acquisition, substantial repair or alteration, construction, development
or substantial improvement of such Operating Property or (ii) the placing in
operation of such Operating Property or of such Operating Property as so
substantially repaired or altered, constructed, developed or substantially

Property without equally and ratably securing the Notes of this Series or

transfer for cash, an amount equal to the net proceeds thereof (but not in

amount equal to the fair value (as determined by the Board of Directors) of the
Operating Property so leased, to the retirement, within 180 days after the later
to occur of the effective date of such Sale and Lease-Back Transaction or the
Release Date, of Notes or other Debt of the Company ranking senior to, or
equally with, the Notes; provided, however, that any such retirement of Notes
shall be in accordance with the terms and provisions of the Indenture and the
Notes and provided, further, that the amount to be applied to such retirement of
Notes or other Debt shall be reduced by an amount equal to the sum of (a) an
amount equal to the redemption price with respect to Notes delivered within such
180-day period

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

     This Global Note is a global security in respect of a duly authorized issue
of 6.65% Senior Notes, Series due July 15, 2027 (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 NationsBank, N.A., as successor trustee (the "TRUSTEE", which
term includes any subsequent successor Trustee under the Indenture) to Boatmen's
First National Bank of Oklahoma, 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
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

amount to $125,000,000.

     Prior to the Release Date (as hereinafter defined), the Notes will be
secured by first mortgage bonds (the "SENIOR NOTE FIRST MORTGAGE BONDS")
delivered by the Company to the Trustee for the benefit of the Holders of the
Notes, issued under the Trust Indenture, dated as of February 1, 1945, from the
Company to NationsBank, N.A., as successor trustee to The First National Bank

the "FIRST MORTGAGE").  Reference is made to the First Mortgage and the
Indenture for a description of the rights of the Trustee as holder of the Senior
Note First Mortgage Bonds, the property mortgaged and pledged, under the First
Mortgage and the rights of the Company and of the Mortgage Trustee in respect
thereof, the duties and immunities of the Mortgage Trustee and the terms and
conditions upon which the Senior Note First Mortgage Bonds are secured and the
circumstances under which additional first mortgage bonds may be issued.

     FROM AND AFTER SUCH TIME AS ALL FIRST MORTGAGE BONDS (OTHER THAN SENIOR

THROUGH PAYMENT, REDEMPTION 

                                       -2-
<PAGE>

OR OTHERWISE (INCLUDING THOSE FIRST MORTGAGE BONDS "DEEMED TO BE PAID" WITHIN 
THE MEANING OF THAT TERM AS USED IN ARTICLE X OF THE FIRST MORTGAGE) AT, 
BEFORE OR AFTER THE MATURITY THEREOF (THE "RELEASE DATE"), THE SENIOR NOTE 
FIRST MORTGAGE BONDS SHALL CEASE TO SECURE THE NOTES IN ANY MANNER.  IN 
CERTAIN CIRCUMSTANCES PRIOR TO THE RELEASE DATE AS PROVIDED IN THE INDENTURE, 
THE COMPANY IS PERMITTED TO REDUCE THE AGGREGATE PRINCIPAL AMOUNT OF A SERIES 
OF SENIOR NOTE FIRST MORTGAGE BONDS HELD BY THE TRUSTEE, BUT IN NO EVENT 
PRIOR TO THE RELEASE DATE TO AN AMOUNT LESS THAN THE AGGREGATE OUTSTANDING 
PRINCIPAL AMOUNT OF THE SERIES OF NOTES INITIALLY ISSUED CONTEMPORANEOUSLY 
WITH SUCH SENIOR NOTE FIRST MORTGAGE BONDS. 

     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.

     The Company, at its option, may redeem on any date on or after August 15,
2007, all or, from time to time, any part of this Global Note at a redemption
price equal to the greater of (i) 100% of the principal amount of this Global
Note to be redeemed and (ii) the sum of the present values of the remaining
scheduled payments of principal and interest thereon discounted to the
redemption date on a semi-annual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Rate, plus in each case accrued and unpaid
interest thereon to the date of redemption.

     "Treasury Rate" means, with respect to any redemption date, the rate per
annum equal to the semi-annual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such redemption date.

     "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Notes of this Series to be redeemed that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of Notes of this Series.  "Independent Investment
Banker" means one of the Reference Treasury Dealers appointed by the Senior Note
Trustee after consultation with the Company.

     "Comparable Treasury Price" means, with respect to any redemption date,
(i) the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
business day preceding such redemption date, as set forth in the daily
statistical release (or any successor release) published by the Federal Reserve
Bank of New York and designated "Composite 3:30 p.m.  Quotations for U.S.
Government Securities" or (ii) if such release (or any successor release) is not
published or does not contain such prices on such third business day, (A) the
average of the Reference Treasury Dealer Quotations for such redemption date,
after excluding the highest and lowest of such Reference Treasury Dealer
Quotations, or (B) if the Senior Note Trustee is unable to obtain at least four
such Reference Treasury Dealer Quotations, the average of all such Quotations
obtained.  "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
the Senior Note Trustee, of the bid and asked prices for the Comparable Treasury
Issue (expressed in each case as a percentage of its principal amount) quoted in
writing to the Senior Note Trustee by such Reference Treasury Dealer at 5:00
p.m., New York City time, on the third business day preceding such redemption
date.

     "Reference Treasury Dealer" means each of Merrill Lynch, Pierce, Fenner &
Smith Incorporated, Bear, Stearns & Co. Inc., Lehman Brothers Inc. and Morgan
Stanley & Co. Incorporated, 

                                       -3-
<PAGE>

and their respective successors; provided, however, that if any of the 
foregoing shall cease to be a primary U.S. Government securities dealer in 
New York City (a "Primary Treasury Dealer"), the Company shall substitute 
therefor another Primary Treasury Dealer.

     Notice of redemption will be given by 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 portion hereof will be issued in the name of the
Noteholder hereof upon the surrender hereof.

     The Notes of this Series will be repayable on July 15, 2007, at the option
of the Holders thereof, at 100% of their principal amount, together with accrued
and unpaid interest to July 15, 2007.  In order for this Global Note to be
repaid, the Company must receive at the corporate trust office of the Trustee
during the period from and including May 15, 2007 to and including the close of
business on June 15, 2007 (or if June 15, 2007 is not a Business Day, the next
succeeding Business Day): (i) this Global Note with the form entitled "Option to
Elect Repayment" on this Global Note duly completed, or (ii) a telegram, telex,
facsimile transmission or letter from a member of a national securities exchange
or the National Association of Securities Dealers, Inc. or a commercial bank or
a trust company in the United States of America setting forth the name of the
Holder of this Global Note, the principal amount of this Global Note, the
principal amount of this Global Note to be repaid, a statement that the option
to elect repayment is being exercised thereby and a guarantee that this Global
Note (with the form entitled "Option to Elect Repayment" on this Global Note
duly completed) will be received at the Trustee's corporate trust office, no
later than five Business Days after the date of such telegram, telex, facsimile
transmission or letter and this Global Note and form duly completed are received
at the Trustee's office, by such fifth Business Day.  Effective exercise of the
repayment option by the Holder of any Note of this Series shall be irrevocable. 
No transfer or exchange of any Note of this Series (or, in the event that any
Note of this Series is to be repaid in part, such portion of the Note of this
Series to be repaid) will be permitted after exercise of the repayment option. 
The repayment option may be exercised by the Holder of a Note of this Series for
less than the entire principal amount of the Note of this Series, provided the
principal amount which is to be repaid is set forth on the form entitled "Option
to Elect Repayment" on the Note of this Series and is equal to $1,000 or any
integral multiple thereof.  All questions as to the validity, eligibility
(including time of receipt) and acceptance of any Note of this Series for
repayment will be determined by the Company, whose determination will be final,
binding and non-appealable.  Upon timely delivery of a Note of this Series to
the Trustee with the "Option to Elect Repayment" form completed in accordance
with the foregoing, the outstanding principal amount of such Note of this Series
(or portion thereof indicated on the "Option to Elect Repayment") shall become
due and payable on July 15, 2007, at a price equal to 100% of the principal
amount to be repaid plus accrued and unpaid interest to July 15, 2007.

     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 

                                       -4-
<PAGE>

including obligations to register the transfer or exchange of Notes, replace

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.

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

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.

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 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

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

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

     OKLAHOMA GAS AND ELECTRIC COMPANY, a corporation of the State of Oklahoma
(the "COMPANY"), for value received hereby promises to pay to ___________ or
registered assigns, the principal sum of 

                     ONE HUNDRED TWENTY FIVE 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 in each year, commencing on the first such Interest
Payment Date succeeding the applicable Original Issue Date set forth above, 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 Note is 

<PAGE>

registered at the close of business on the Regular Record Date for such 
interest, which shall be the December 31 or the June 30, as the case may be, 
next preceding such Interest Payment Date; provided that the first Interest 
Payment Date for any part of this 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 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 6.50% Senior Notes, Series due July 15, 2017 (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 NationsBank, N.A., as successor trustee (the "TRUSTEE", which
term includes any subsequent successor Trustee under the Indenture) to Boatmen's
First National Bank of Oklahoma 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
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, limited in aggregate principal
amount to $125,000,000.

     Prior to the Release Date (as hereinafter defined), the Notes will be
secured by first mortgage bonds (the "SENIOR NOTE FIRST MORTGAGE BONDS")
delivered by the Company to the Trustee for the benefit of the Holders of the
Notes, issued under the Trust Indenture, dated as of February 1, 1945, from the
Company to NationsBank, N.A., as successor trustee to The First National Bank
and Trust Company of Oklahoma City and to Boatmen's First National Bank of
Oklahoma (the "MORTGAGE TRUSTEE"), as supplemented and modified (collectively,
the "FIRST MORTGAGE").  Reference is made to the First Mortgage and the
Indenture for a description of the rights of the Trustee as holder of the Senior
Note First Mortgage Bonds, the property mortgaged and pledged, under the First
Mortgage and the rights of the Company and of the Mortgage Trustee in respect
thereof, the duties and immunities of the Mortgage Trustee and the terms and
conditions upon which the Senior Note First Mortgage Bonds are secured and the
circumstances under which additional first mortgage bonds may be issued.

     FROM AND AFTER SUCH TIME AS ALL FIRST MORTGAGE BONDS (OTHER THAN SENIOR
NOTE FIRST MORTGAGE BONDS) ISSUED UNDER THE FIRST MORTGAGE HAVE BEEN RETIRED
THROUGH PAYMENT, REDEMPTION 

                                       -2-
<PAGE>

OR OTHERWISE (INCLUDING THOSE FIRST MORTGAGE BONDS "DEEMED TO BE PAID" WITHIN 
THE MEANING OF THAT TERM AS USED IN ARTICLE X OF THE FIRST MORTGAGE) AT, 
BEFORE OR AFTER THE MATURITY THEREOF (THE "RELEASE DATE"), THE SENIOR NOTE 
FIRST MORTGAGE BONDS SHALL CEASE TO SECURE THE NOTES IN ANY MANNER.  IN 
CERTAIN CIRCUMSTANCES PRIOR TO THE RELEASE DATE AS PROVIDED IN THE INDENTURE, 
THE COMPANY IS PERMITTED TO REDUCE THE AGGREGATE PRINCIPAL AMOUNT OF A SERIES 
OF SENIOR NOTE FIRST MORTGAGE BONDS HELD BY THE TRUSTEE, BUT IN NO EVENT 
PRIOR TO THE RELEASE DATE TO AN AMOUNT LESS THAN THE AGGREGATE OUTSTANDING 
PRINCIPAL AMOUNT OF THE SERIES OF NOTES INITIALLY ISSUED CONTEMPORANEOUSLY 
WITH SUCH SENIOR NOTE FIRST MORTGAGE BONDS. 

     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.

     The Company, at its option, may redeem on any date on or after August 15,
2004, all or, from time to time, any part of this Global Note at a redemption
price equal to the greater of (i) 100% of the principal amount of this Global
Note to be redeemed and (ii) the sum of the present values of the remaining
scheduled payments of principal and interest thereon discounted to the
redemption date on a semi-annual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Rate, plus in each case accrued and unpaid
interest thereon to the date of redemption.

     "Treasury Rate" means, with respect to any redemption date, the rate per
annum equal to the semi-annual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such redemption date.

     "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Notes of this Series to be redeemed that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of Notes of this Series.  "Independent Investment
Banker" means one of the Reference Treasury Dealers appointed by the Senior Note
Trustee after consultation with the Company.

     "Comparable Treasury Price" means, with respect to any redemption date,
(i) the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
business day preceding such redemption date, as set forth in the daily
statistical release (or any successor release) published by the Federal Reserve
Bank of New York and designated "Composite 3:30 p.m.  Quotations for U.S.
Government Securities" or (ii) if such release (or any successor release) is not
published or does not contain such prices on such third business day, (A) the
average of the Reference Treasury Dealer Quotations for such redemption date,
after excluding the highest and lowest of such Reference Treasury Dealer
Quotations, or (B) if the Senior Note Trustee is unable to obtain at least four
such Reference Treasury Dealer Quotations, the average of all such Quotations
obtained.  "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
the Senior Note Trustee, of the bid and asked prices for the Comparable Treasury
Issue (expressed in each case as a percentage of its principal amount) quoted in
writing to the Senior Note Trustee by such Reference Treasury Dealer at 5:00
p.m., New York City time, on the third business day preceding such redemption
date.

     "Reference Treasury Dealer" means each of Merrill Lynch, Pierce, Fenner &
Smith Incorporated, Bear, Stearns & Co. Inc., Lehman Brothers Inc. and Morgan
Stanley & Co. Incorporated,

                                       -3-
<PAGE>

and their respective successors; provided, however, that if any of the 
foregoing shall cease to be a primary U.S. Government securities dealer in 
New York City (a "Primary Treasury Dealer"), the Company shall substitute 
therefor another Primary Treasury Dealer.

     Notice of redemption will be given by 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 portion hereof will be issued in the name of the
Noteholder hereof upon the surrender hereof.

     The Notes of this Series will be repayable on July 15, 2004, at the option
of the Holders thereof, at 100% of their principal amount, together with accrued
and unpaid interest to July 15, 2004.  In order for this Global Note to be
repaid, the Company must receive at the corporate trust office of the Trustee
during the period from and including May 15, 2004 to and including the close of
business on June 15, 2004 (or if June 15, 2004 is not a Business Day, the next
succeeding Business Day): (i) this Global Note with the form entitled "Option to
Elect Repayment" on this Global Note duly completed, or (ii) a telegram, telex,
facsimile transmission or letter from a member of a national securities exchange
or the National Association of Securities Dealers, Inc. or a commercial bank or
a trust company in the United States of America setting forth the name of the
Holder of this Global Note, the principal amount of this Global Note, the
principal amount of this Global Note to be repaid, a statement that the option
to elect repayment is being exercised thereby and a guarantee that this Global
Note (with the form entitled "Option to Elect Repayment" on this Global Note
duly completed) will be received at the Trustee's corporate trust office, no
later than five Business Days after the date of such telegram, telex, facsimile
transmission or letter and this Global Note and form duly completed are received
at the Trustee's office, by such fifth Business Day.  Effective exercise of the
repayment option by the Holder of any Note of this Series shall be irrevocable. 
No transfer or exchange of any Note of this Series (or, in the event that any
Note of this Series is to be repaid in part, such portion of the Note of this
Series to be repaid) will be permitted after exercise of the repayment option. 
The repayment option may be exercised by the Holder of a Note of this Series for
less than the entire principal amount of the Note of this Series, provided the
principal amount which is to be repaid is set forth on the form entitled "Option
to Elect Repayment" on the Note of this Series and is equal to $1,000 or any
integral multiple thereof.  All questions as to the validity, eligibility
(including time of receipt) and acceptance of any Note of this Series for
repayment will be determined by the Company, whose determination will be final,
binding and non-appealable.  Upon timely delivery of a Note of this Series to
the Trustee with the "Option to Elect Repayment" form completed in accordance
with the foregoing, the outstanding principal amount of such Note of this Series
(or portion thereof indicated on the "Option to Elect Repayment") shall become
due and payable on July 15, 2004, at a price equal to 100% of the principal
amount to be repaid plus accrued and unpaid interest to July 15, 2004.

     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 

                                       -4-
<PAGE>

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 and, upon such declaration, the Trustee can demand the
redemption of the Senior Note First Mortgage Bonds as 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 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 officer, 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.

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed.

Note Series D on the Demand Redemption Date; but no such rescission shall extend

to  be repurchased on July 15, 2007 at  a price equal to the principal amount of

Oklahoma Gas and Electric Company

Oklahoma City, Oklahoma  73101

     Re:  $250,000,000 Principal Amount of Securities

Gentlemen: 

     We have examined the Form S-3 Registration Statement, dated April 5, 1996
(the "Registration Statement"), of Oklahoma Gas and Electric Company (the
"Company"), to which this opinion is an exhibit, for the registration under the
Securities Act of 1933, as amended (the "Act"), of an aggregate principal amount
of $250,000,000 of notes ("Senior Notes") issued under the Indenture, dated
October 1, 1995, as heretofore supplemented and amended by a supplemental
indenture and a new supplemental indenture for each series of Senior Notes, all
from the Company to NationsBank, N.A., as successor trustee (such Indenture, as
supplemented and as to be supplemented, is herein referred to as the "Senior
Note Indenture"), which Senior Notes are to be secured by First Mortgage Bonds
of one or more series (the "Bonds") to be issued under the Trust Indenture dated
February 1, 1945 as heretofore supplemented and amended by supplemental trust
indentures and a new supplemental trust indenture (the "New Supplemental
Indentures") for each series of Bonds all from the Company to NationsBank, N.A.,
as successor trustee (such Trust Indenture, as supplemented and as to be
supplemented, is herein referred to as the "First Mortgage Indenture").  The
Senior Notes and the Bonds which are to secure such Senior Notes are herein
referred to collectively as the "Securities".  We have examined all records,
instruments, and documents which we have deemed necessary for the purpose of
this opinion, including the Registration Statement on Form S-3 under the
Securities Act of 1933, as amended, relating to the Securities to be filed by
the Company pursuant to the Act. 

     Based upon the foregoing and upon our general familiarity with the
properties and affairs of the Company, we are of the opinion that: 

<PAGE>

     1.   The Company is a validly organized and legally existing corporation in
good standing under the laws of the State of Oklahoma and is authorized to
conduct and operate its business as a public utility in the State of Oklahoma. 

     2.   The First Mortgage Indenture, other than the New Supplemental
Indentures, is a valid, legal and binding instrument of the Company. 

     3.   The Senior Note Indenture, other than any new supplemental indentures,
is a valid, legal and binding instrument of the Company. 

     4.   With respect to the Senior Notes, when, as and if the Senior Notes and
one or more new supplemental indentures relating thereto have been duly executed
and delivered, and the consideration for the Senior Notes duly received by the
Company, all in the manner contemplated by the said Registration Statement, and
with respect to the Bonds, when, as and if the Bonds and one or more New
Supplemental Indentures relating thereto have been duly authorized, executed,
delivered, filed and recorded as required by law, all in the manner contemplated
by the said Registration Statement, the Bonds and the Senior Notes will be
legally issued and binding obligations of the Company. 

     5.   The statements made in the above-mentioned Registration Statement and
in the related Prospectus, purporting to be made or based upon our opinion
correctly set forth our opinion upon said respective matters. 

                              Respectfully, 



                              RAINEY, ROSS, RICE & BINNS
