                       OKLAHOMA GAS AND ELECTRIC COMPANY
 
    Oklahoma Gas and Electric Company, an Oklahoma corporation (the "Company")
incorporated in 1902 under the laws of the Territory of Oklahoma, is an electric
public utility company with its principal executive offices located at 101 North
Robinson, P.O. Box 321, Oklahoma City, Oklahoma 73101-0321. Telephone (405)
553-3000. The Company is a subsidiary of OGE Energy Corp. ("OGE Energy"), which
is a public utility holding company incorporated in the State of Oklahoma and
located in Oklahoma City, Oklahoma.
 
    The Company is the largest operating electric utility in Oklahoma. The
Company owns and operates an interconnected electric production, transmission
and distribution system which includes eight active generating stations with a
total capability of 5,647,300 kilowatts. The Company furnishes retail electric
service in 274 communities and contiguous rural and suburban territories in
Oklahoma and western Arkansas (population served estimated by the Company at
1,700,000). It also sells electric energy at wholesale for resale in 5
communities and to 2 rural electric cooperatives in those states. The area
served by the Company embraces approximately 30,000 square miles, which includes
Oklahoma City, the largest city in Oklahoma, and the section of Arkansas in the
general area of Ft. Smith, the second largest city in Arkansas. Of the total 279
communities served, 248 are located in Oklahoma and 31 in Arkansas.
Approximately 91% of the Company's electric operating revenues for the year
ended December 31, 1997, was derived from sales in Oklahoma and approximately 9%
from sales in Arkansas.
 
RESTRUCTURING
 
    The Company and its former subsidiary, Enogex Inc., and Enogex Inc.'s
subsidiaries (collectively, "Enogex") became subsidiaries of OGE Energy on
December 31, 1996 pursuant to a mandatory share exchange whereby each share of
outstanding common stock of the Company was exchanged on a share-for-share basis
for common stock of OGE Energy. Immediately following this exchange, the Company
transferred its shares of Enogex stock to OGE Energy and Enogex became a direct
subsidiary of OGE Energy. OGE Energy now serves as the parent company to the
Company and Enogex. For purposes of the Company's financial statements, Enogex
is shown as discontinued operations. The New Notes will be obligations solely of
the Company and not of OGE Energy or Enogex.

                            DESCRIPTION OF NEW NOTES
 
GENERAL
 
    Each series of New Notes is to be an initial issue of a new series of senior
notes (the "Senior Notes") issued under the Indenture dated as of October 1,
1995, as supplemented by Supplemental Indenture No. 1, dated as of October 16,
1995, Supplemental Indenture No. 2, dated as of July 1, 1997, and as to be
further supplemented by a new supplemental indenture for such series of New
Notes (collectively, the "Senior Note Indenture") between the Company and The
Bank of New York, as successor trustee (the "Senior Note Trustee") to Boatmen's
First National Bank of Oklahoma. The following summaries of certain provisions
of the Senior Note Indenture do not purport to be complete and are subject to,
and qualified in their entirety by, all of the provisions of the Senior Note
Indenture which is an exhibit to the Registration Statement of which this
Prospectus is a part and which is incorporated herein by this
 
                                       4
<PAGE>
reference. Unless otherwise indicated, references to Section numbers under this
caption are references to the Section numbers of the Senior Note Indenture.
 
    Until the Release Date (as defined below), the Senior Notes (including any
New Notes issued prior to the Release Date) will be secured by one or more
series of the Company's first mortgage bonds issued and delivered by the Company
to the Senior Note Trustee. See "Security; Release Date." ON THE RELEASE DATE,
ANY THEN OUTSTANDING SENIOR NOTES (INCLUDING ANY NEW NOTES ISSUED PRIOR TO THE
RELEASE DATE) WILL CEASE TO BE SECURED BY FIRST MORTGAGE BONDS, WILL BECOME
UNSECURED GENERAL OBLIGATIONS OF THE COMPANY AND WILL RANK ON A PARITY WITH
OTHER UNSECURED INDEBTEDNESS OF THE COMPANY. AS OF JANUARY 31, 1998, THERE WERE
OUTSTANDING THREE SERIES OF FIRST MORTGAGE BONDS IN AN AGGREGATE PRINCIPAL
AMOUNT EQUAL TO $87.5 MILLION. The Release Date will occur when all such first
mortgage bonds are retired or redeemed. SENIOR NOTES (INCLUDING NEW NOTES)
ISSUED ON OR AFTER THE RELEASE DATE WILL NOT BE SECURED BY ANY FIRST MORTGAGE
BONDS AND WILL BE UNSECURED GENERAL OBLIGATIONS OF THE COMPANY. The Prospectus
Supplement applicable to each series of Offered Notes will specify whether such
Offered Notes will be secured or unsecured. As of December 31, 1997, the Company
had issued four series of Senior Notes in the aggregate principal amount of $470
million (the "Prior Senior Notes"). The Senior Note Indenture provides that, in
addition to the New Notes offered hereby, additional Senior Notes may be issued
thereunder, without limitation as to aggregate principal amount, provided that,
prior to the Release Date, the amount of Senior Notes that may be issued and
outstanding cannot exceed the amount of first mortgage bonds that the Company is
able to issue under its First Mortgage Indenture. See "FIRST MORTGAGE BONDS AND
FIRST MORTGAGE INDENTURE--Issuance of Additional Bonds." At December 31, 1997,
the Company could issue more than $1.1 billion of additional first mortgage
bonds at an assumed 7.60% interest rate.
 
    There is no requirement under the Senior Note Indenture that future issues
of debt securities of the Company be issued under the Senior Note Indenture, and
the Company will be free to employ other indentures or documentation, containing
provisions different from those included in the Senior Note Indenture or
applicable to one or more issues of Senior Notes (including the New Notes), in
connection with future issues of such other debt securities.
 
    The Senior Note Indenture provides that the New Notes will be issued in one
or more series, may be issued at various times, may have differing maturity
dates and may bear interest at differing rates. The Prospectus Supplement
applicable to each issue of Offered Notes will specify: (1) the designation and
aggregate principal amount of such Offered Notes; (2) the date on which such
Offered Notes will mature; (3) the interest rate or rates, or method of
calculation of such rate or rates, on such Offered Notes, and the date from
which such interest shall accrue; (4) the dates on which such interest will be
payable; (5) the record dates for payments of interest; (6) any redemption
terms; (7) the period or periods within which, the price or prices at which and
the terms and conditions upon which such Offered Notes may be repaid, in whole
or in part, at the option of the holder thereof; and (8) other specific terms
applicable to such Offered Notes, including whether such Offered Notes will be
secured or unsecured. Unless otherwise indicated in the applicable Prospectus
Supplement, the New Notes will be denominated in United States currency in
minimum denominations of $1,000 and integral multiples thereof.
 
    Unless otherwise indicated in the applicable Prospectus Supplement, there
are no provisions in the Senior Note Indenture or the New Notes that require the
Company to redeem, or permit the holders to cause a redemption of, the New Notes
or that otherwise protect the holders in the event that the Company incurs
substantial additional indebtedness, whether or not in connection with a change
in control of the Company. However, any change in control transaction that
involves the incurrence of additional long-term indebtedness (as notes, first
mortgage bonds or otherwise) by the Company in such a transaction would require
approval of state utility regulatory authorities and, possibly, of federal
utility regulatory authorities. Management believes that such approvals would be
unlikely in any transaction that would result in the Company, or a successor to
the Company, having a highly leveraged capital structure.

REGISTRATION, TRANSFER AND EXCHANGE
 
    New Notes of any series will be exchangeable for other New Notes of the same
series of any authorized denominations and of a like aggregate principal amount
and tenor. (Section 2.06)
 
    Unless otherwise indicated in the applicable Prospectus Supplement, New
Notes may be presented for registration of transfer (duly endorsed or
accompanied by a duly executed written instrument of transfer), at the office of
the Senior Note Trustee and maintained for such purpose with respect to any
series of New Notes and referred to in the applicable Prospectus Supplement,
without service charge and upon payment of any taxes and other governmental
charges as described in the Senior Note Indenture. Such transfer or exchange
will be effected upon the Senior Note Trustee being satisfied with the documents
of title and indemnity of the person making the request. (Sections 2.06 and
2.07)
 
    In the event of any redemption of New Notes of any series, the Senior Note
Trustee will not be required to exchange or register a transfer of any New Notes
of such series selected, called or being called for redemption except, in the
case of any New Note to be redeemed in part, the portion thereof not to be so
redeemed. (Section 2.06) See "BOOK-ENTRY SYSTEM."
 
PAYMENT AND PAYING AGENTS
 
    Principal of and interest and premium, if any, on New Notes issued in the
form of Global Securities will be paid in the manner described below under the
caption "BOOK-ENTRY SYSTEM." Unless otherwise indicated in the applicable
Prospectus Supplement, interest on New Notes that are in the form of
certificated securities will be paid by check to the person entitled thereto as
such person's name appears in the register for the New Notes maintained by the
Senior Note Trustee; however, a holder of Senior Notes of one or more series
under the Senior Note Indenture in the aggregate principal amount of $10,000,000
or more having the same interest payment dates will be entitled to receive
payments of interest on such series by wire transfer of immediately available
funds to a bank within the continental United States if appropriate wire
transfer instructions have been received by the Senior Note Trustee on or prior
to the applicable regular record date. (Section 2.12) Unless otherwise indicated
in the applicable Prospectus Supplement, the principal of, and interest at
maturity or redemption and premium, if any, on New Notes in the form of
certificated securities will be payable in immediately available funds at the
office of the Senior Note Trustee. (Section 2.12)
 
    All monies paid by the Company to a paying agent for the payment of
principal of, interest or premium, if any, on any New Note which remain
unclaimed at the end of two years after such principal, interest or premium
shall have become due and payable will be repaid to the Company and the holder
of such New Note will thereafter look only to the Company for payment thereof.
(Section 5.04)
 
SECURITY; RELEASE DATE
 
    Until the Release Date, the Senior Notes (including any New Notes issued
prior thereto) will be secured by one or more series of the Company's first
mortgage bonds ("Senior Note Mortgage Bonds") issued and delivered by the
Company to the Senior Note Trustee (see "FIRST MORTGAGE BONDS AND FIRST MORTGAGE
INDENTURE"). Upon the issuance of a series of Senior Notes (including New Notes)
prior to the Release Date, the Company will simultaneously issue and deliver to
the Senior Note Trustee, as security for all Senior Notes, a series of Senior
Note Mortgage Bonds that will have the same stated rate or rates of interest (or
interest calculated in the same manner), interest payment dates, stated maturity
date and redemption provisions, and will be in the same aggregrate principal
amount as the series of the Senior Notes (including New Notes) being issued.
(Section 4.10) Payment by the Company to the Senior Note Trustee of principal
of, premium, if any, and interest on, a series of Senior Note Mortgage Bonds
will be applied by the Senior Note Trustee to satisfy the Company's obligations
with respect to principal of, premium, if any, and interest on, the Senior
Notes. (Section 4.11) SENIOR NOTES (INCLUDING NEW NOTES) ISSUED ON OR AFTER THE
RELEASE DATE WILL NOT BE SECURED BY ANY FIRST MORTGAGE BONDS AND WILL BE
UNSECURED GENERAL OBLIGATIONS OF THE COMPANY.
 
                                       6
<PAGE>
    THE RELEASE DATE WILL BE THE DATE THAT ALL FIRST MORTGAGE BONDS ("FIRST
MORTGAGE BONDS") OF THE COMPANY ISSUED AND OUTSTANDING UNDER THE FIRST MORTGAGE
INDENTURE (HEREINAFTER DEFINED), OTHER THAN SENIOR NOTE MORTGAGE BONDS, HAVE
BEEN RETIRED (AT, BEFORE OR AFTER THE MATURITY THEREOF) THROUGH PAYMENT,
REDEMPTION OR OTHERWISE (INCLUDING THOSE FIRST MORTGAGE BONDS DEEMED TO BE PAID
WITHIN THE MEANING OF THE FIRST MORTGAGE INDENTURE). AS OF JANUARY 31, 1998,
THERE WERE OUTSTANDING THREE SERIES OF FIRST MORTGAGE BONDS OTHER THAN SENIOR
NOTE MORTGAGE BONDS IN AN AGGREGATE PRINCIPAL AMOUNT EQUAL TO $87.5 MILLION. ON
THE RELEASE DATE, THE SENIOR NOTE TRUSTEE WILL DELIVER TO THE COMPANY FOR
CANCELLATION ALL SENIOR NOTE MORTGAGE BONDS AND THE COMPANY WILL CAUSE THE
SENIOR NOTE TRUSTEE TO PROVIDE NOTICE TO ALL HOLDERS OF SENIOR NOTES (INCLUDING
ANY NEW NOTES ISSUED PRIOR TO THE RELEASE DATE) OF THE OCCURRENCE OF THE RELEASE
DATE. AS A RESULT, ON THE RELEASE DATE, THE SENIOR NOTE MORTGAGE BONDS SHALL
CEASE TO SECURE THE SENIOR NOTES (INCLUDING ANY NEW NOTES ISSUED PRIOR TO THE
RELEASE DATE), AND ANY THEN OUTSTANDING SENIOR NOTES (INCLUDING NEW NOTES) WILL
BECOME UNSECURED GENERAL OBLIGATIONS OF THE COMPANY. (Section 4.11) Each series
of Senior Note Mortgage Bonds will be a series of First Mortgage Bonds of the
Company, all of which are secured by a lien on certain property owned by the
Company. In certain circumstances prior to the Release Date, the Company is
permitted to reduce the aggregate principal amount of a series of Senior Note
Mortgage Bonds held by the Senior Note Trustee, but in no event to an amount
lower than the aggregate outstanding principal amount of the series of Senior
Notes initially issued contemporaneously with such Senior Note Mortgage Bonds.
(Section 4.08) Following the Release Date, the Company will cause the First
Mortgage Indenture to be closed and the Company will not issue any additional
First Mortgage Bonds under the First Mortgage Indenture. (Section 4.11) While
the Company will be precluded after the Release Date from issuing additional
First Mortgage Bonds, the Company will not be precluded under the Senior Note
Indenture or New Notes from issuing or assuming other secured debt, or incurring
liens on its property, except to the extent indicated below under "Limitation on
Liens" and except as otherwise indicated in the applicable Prospectus
Supplement.
 
EVENTS OF DEFAULT
 
    The following constitute events of default under the Senior Note Indenture:
(a) default in the payment of principal of or premium, if any, on any Senior
Note when due and payable and continuance of such default for five days; (b)
default in the payment of interest on any Senior Note when due which continues
for 30 days; (c) default in the performance or breach of any other covenant or
warranty of the Company in the Senior Note Indenture and the continuation
thereof for 90 days after written notice to the Company as provided in the
Senior Note Indenture; (d) prior to the Release Date, the occurrence of a
Completed Default (hereinafter defined) under the First Mortgage Indenture, of
which the First Mortgage Trustee (hereinafter defined), the Company or the
holders of at least 25% in aggregate principal amount of the outstanding Senior
Notes have given written notice thereof to the Senior Note Trustee; and (e)
certain events of bankruptcy, insolvency, assignment or receivership of the
Company. (Section 8.01)
 
    If an event of default occurs and is continuing, either the Senior Note
Trustee or the holders of a majority in aggregate principal amount of the
outstanding Senior Notes may declare the principal amount of all Senior Notes to
be due and payable immediately. Upon such acceleration of the Senior Notes prior
to the Release Date, the Senior Note Trustee is empowered to cause the mandatory
redemption of the Senior Note Mortgage Bonds. At any time after an acceleration
of the Senior Notes has been declared, but before a judgment or decree of the
immediate payment of the principal amount of the Senior Notes has been obtained
and, prior to the Release Date, so long as all First Mortgage Bonds have not
been accelerated, if the Company pays or deposits with the Senior Note Trustee a
sum sufficient to pay all matured installments of interest and the principal and
any premium which has become due otherwise than by acceleration and all defaults
shall have been cured or waived, then such payment or deposit will cause an
automatic rescission and annulment of the acceleration of the Senior Notes.
(Section 8.01)
 
                                       7
<PAGE>
    The Senior Note Indenture provides that the Senior Note Trustee generally
will be under no obligation to exercise any of its rights or powers under the
Senior Note Indenture at the request or direction of any of the holders unless
such holders have offered to the Senior Note Trustee reasonable security or
indemnity. (Section 9.02) The holders of a majority in principal amount of the
outstanding Senior Notes generally will have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Senior Note Trustee, or of exercising any trust or power conferred on the Senior
Note Trustee. (Section 8.07) Each holder of any Senior Note has the right to
institute a proceeding with respect to the Senior Note Indenture, but such right
is subject to certain conditions precedent specified in the Senior Note
Indenture. (Section 8.04) The Senior Note Indenture provides that the Senior
Note Trustee, within 90 days after the occurrence of a default with respect to
the Senior Notes, is required to give the holders of the Senior Notes notice of
such default, unless cured or waived, but, except in the case of default in the
payment of principal of, or premium, if any, or interest on, any Senior Notes,
the Senior Note Trustee may withhold such notice if it determines in good faith
that it is in the interest of such holders to do so. (Section 8.08) The Company
is required to deliver to the Senior Note Trustee each year a certificate as to
whether or not, to the knowledge of the officers signing such certificate, the
Company is in compliance with the conditions and covenants under the Senior Note
Indenture. (Section 6.06)
 
MODIFICATION
 
    Modification and amendment of the Senior Note Indenture may be effected by
the Company and the Senior Note Trustee with the consent of the holders of a
majority in principal amount of the outstanding Senior Notes affected thereby,
provided that no such modification or amendment may, without the consent of the
holder of each outstanding Senior Note affected thereby, (a) change the maturity
date of any Senior Note; (b) reduce the rate or extend the time of payment of
interest on any Senior Note; (c) reduce the principal amount of, or premium
payable on, any Senior Note; (d) change the coin or currency of any payment of
principal of, or any premium or interest on, any Senior Note; (e) change the
date on which any Senior Note may be redeemed or repaid at the option of the
holder thereof or adversely affect the rights of a holder to institute suit for
the enforcement of any payment on or with respect to any Senior Note; (f) impair
the interest of the Senior Note Trustee in the Senior Note Mortgage Bonds held
by it or, prior to the Release Date, reduce the principal amount of any series
of Senior Note Mortgage Bonds securing the Senior Notes to an amount less than
the principal amount of the related series of Senior Notes or alter the payment
provisions of such Senior Note Mortgage Bonds in a manner adverse to the holders
of the Senior Notes; or (g) modify the foregoing requirements or reduce the
percentage of outstanding Senior Notes necessary to modify or amend the Senior
Note Indenture or to waive any past default to less than a majority.
Modification and amendment of the Senior Note Indenture may be effected by the
Company and the Senior Note Trustee without the consent of the holders (a) to
add to the covenants of the Company for the benefit of the holders or to
surrender a right conferred on the Company in the Senior Note Indenture; (b) to
add further security for the Senior Notes; or (c) to make certain other
modifications, generally of a ministerial or immaterial nature. (Sections 13.01
and 13.02)
 
DEFEASANCE AND DISCHARGE
 
    The Senior Note Indenture provides that the Company will be discharged from
any and all obligations in respect to the Senior Notes and the Senior Note
Indenture (except for certain obligations such as obligations to register the
transfer or exchange of Senior Notes, replace stolen, lost or mutilated Senior
Notes and maintain paying agencies) if, among other things, the Company
irrevocably deposits with the Senior Note Trustee, in trust for the benefit of
holders of Senior Notes, money or certain United States government obligations,
or any combination thereof, which through the payment of interest thereon and
principal thereof in accordance with their terms will provide money in an amount
sufficient, without reinvestment, to make all payments of principal of, and any
premium and interest on, the Senior Notes on the dates such payments are due in
accordance with the terms of the Senior Note Indenture and the Senior Notes;
provided that, unless all of the Senior Notes are to be due within 90 days of
such deposit by redemption or otherwise, the Company shall also have delivered
to the Senior Note Trustee an opinion of
 
                                       8
<PAGE>
counsel to the effect that the holders of the Senior Notes will not recognize
income, gain or loss for federal income tax purposes as a result of such
defeasance or discharge of the Senior Note Indenture. Thereafter, the holders of
Senior Notes must look only to such deposit for payment of the principal of, and
interest and any premium on, the Senior Notes. (Section 5.01)
 
CONSOLIDATION, MERGER AND SALE OR DISPOSITION OF ASSETS
 
    The Company will not consolidate with or merge into any other corporation or
sell, transfer or otherwise dispose of all or substantially all of its assets
unless the successor or transferee corporation assumes by supplemental indenture
the due and punctual payment of the principal of and premium and interest on all
the Senior Notes and the performance of every covenant of the Senior Note
Indenture to be performed or observed by the Company and, prior to the Release
Date, unless the successor or transferee corporation assumes the Company's
obligations under the First Mortgage Indenture with respect to the Senior Note
Mortgage Bonds. Upon any such consolidation, merger, sale, transfer or other
disposition of all or substantially all of the assets of the Company, the
successor corporation formed by such consolidation or into which the Company is
merged or to which such transfer is made shall succeed to, and be substituted
for, and may exercise every right and power of, the Company under the Senior
Note Indenture with the same effect as if such successor corporation had been
named as the Company therein and the Company will be released from all
obligations under the Senior Note Indenture. The Senior Note Indenture defines
all or substantially all of the assets of the Company as being 50% or more of
the total assets of the Company as shown on the balance sheet of the Company as
of the end of the prior year and specifically permits any such sale, transfer or
other disposition during a calendar year of less than 50% of total assets
without the consent of the holders of the Senior Notes. (Sections 12.01 and
12.02)
 
LIMITATIONS ON LIENS
 
    Unless otherwise specified in the applicable Prospectus Supplement with
respect to any series of Offered Notes, the related supplemental indenture will
provide that, from and after the Release Date and so long as any such Offered
Notes are outstanding, the Company may not issue, assume or guarantee any debt
for money borrowed ("Debt") that is secured by any mortgage, security interest,
pledge or lien ("mortgage") of or upon any Operating Property of the Company,
whether owned at the date of the Senior Note Indenture or thereafter acquired,
and will not permit to exist any Debt secured by any such mortgage created on or
prior to the Release Date, without in any case effectively securing the Offered
Notes and all series of Senior Notes issued prior to or contemporaneously with
such Offered Notes (together with, if the Company shall so determine, any other
Senior Notes or indebtedness of the Company ranking senior to, or equally with,
the Senior Notes) with such Debt equally and ratably, except that this
restriction will not apply to: (1) mortgages on any property existing at the
time of its acquisition; (2) mortgages on property of a corporation existing at
the time such corporation is merged into or consolidated with, or disposes of
substantially all its properties (or those of a division) to, the Company; (3)
mortgages to secure the cost of acquisition, construction, development or
substantial repair, alteration or improvement of property or to secure
indebtedness incurred to provide funds for any such purpose or for reimbursement
of funds previously expended for any such purpose, provided such mortgages are
created or assumed contemporaneously with, or within 18 months after, such
acquisition or completion of substantial repair or alteration, construction,
development or substantial improvement or within six months thereafter pursuant
to a commitment for financing arranged with a lender or investor within such 18
month period; (4) mortgages in favor of the United States of America or any
State thereof, or for the benefit of holders of securities issued by any such
entity, or any department, agency or instrumentality or political subdivision of
the United States of America or any State thereof, to secure any Debt incurred
for the purpose of financing all or any part of the purchase price or the cost
of substantially repairing or altering, constructing, developing or
substantially improving the property subject to such mortgages; or (5) any
extension, renewal or replacement (or successive extensions, renewals or
replacements), in whole or in part, of any mortgage referred to in clauses (1)
through (4), provided, however, that the principal amount of indebtedness
secured thereby and not otherwise authorized by said clauses (1) to (4),
inclusive, shall not exceed the principal amount of indebtedness, plus any
premium or fee payable in connection with any such extension,
 
                                       9
<PAGE>
renewal or replacement, so secured at the time of such extension, renewal or
replacement. However, the foregoing restriction does not apply to the issuance,
assumption or guarantee by the Company of Debt secured by a mortgage which would
otherwise be subject to the foregoing restrictions up to an aggregate amount
which, together with all other secured Debt of the Company (not including
secured Debt permitted under the foregoing exceptions) and the Value (as defined
below) of Sale and Lease-Back Transactions (as defined below) existing at such
time (other than Sale and Lease-Back Transactions the proceeds of which have
been applied to the retirement of certain indebtedness, Sale and Lease-Back
Transactions in which the property involved would have been permitted to be
mortgaged under the foregoing exceptions and Sale and Lease-Back Transactions
that are permitted by the first sentence of "Limitations on Sale and Lease-Back
Transactions" below), does not exceed the greater of 10% of Net Tangible Assets
(as defined below) or 10% of Capitalization (as defined below). (Section 3.01 of
Form of Supplemental Indenture). The supplemental indentures relating to the
Prior Senior Notes contain a covenant with respect to limitations on liens
substantively identical to the foregoing for the benefit of the Prior Senior
Notes. (Section 4.01 of Supplemental Indenture No. 1 and Section 4.01 of
Supplemental Indenture No. 2).
 
LIMITATIONS ON SALE AND LEASE-BACK TRANSACTIONS
 
    Unless otherwise specified in the applicable Prospectus Supplement with
respect to any series of Offered Notes, the related supplemental indenture will
provide that, from and after the Release Date and for so long as such Offered
Notes are outstanding, the Company may 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 Operating Property (except in each case, for
transactions involving leases for a term, including renewals, of not more than
48 months), if the purchaser's commitment is obtained more than 18 months after
the later of the completion of the acquisition or the placing in operation of
such Operating Property or of such Operating Property as constructed or
developed or substantially repaired, altered or improved. This restriction will
not apply if (a) the Company would be entitled pursuant to the provisions
described in the first sentence under "Limitations on Liens" above to issue,
assume or guarantee Debt secured by a mortgage on such Operating Property
without equally and ratably securing the Offered Notes and all series of Senior
Notes issued prior to or contemporaneously with such Offered Notes, (b) after
giving effect to such Sale and Lease-Back Transaction, the Company could incur
pursuant to the provisions described in the second sentence under "Limitations
on Liens," additional Debt secured by mortgages, or (c) the Company applies
within 180 days an amount equal to, in the case of a sale or transfer for cash,
the net proceeds (not exceeding the net book value), and, otherwise, an amount
equal to the fair value (as determined by its Board of Directors) of the
Operating Property so leased to the retirement of Senior Notes or other Debt of
the Company ranking senior to, or equally with, the Senior Notes, subject to
reduction for Senior Notes and such Debt retired during such 180-day period
otherwise than pursuant to mandatory sinking fund or prepayment provisions and
payments at stated maturity. (Section 3.02 of Form of Supplemental Indenture).
The supplemental indentures relating to the Prior Senior Notes contain a
covenant with respect to limitations on Sale and Lease-Back Transactions
substantively identical to the foregoing for the benefit of the Prior Senior
Notes. (Section 4.02 of Supplemental Indenture No. 1 and Section 4.02 of
Supplemental Indenture No. 2).

    "Sale and Lease-Back Transaction" means any arrangement with any person
providing for the leasing to the Company of any Operating Property (except for

and Lease-Back Transaction or (ii) the net book value of such property, as
determined in accordance with generally accepted accounting principles by the
Company at the time of entering into such Sale and Lease-Back Transaction, in
either case multiplied by a fraction, the numerator of which shall be equal to
the number of full years of the term of the lease that is part of such Sale and
Lease-Back Transaction remaining at the time of determination and the
denominator of which shall be equal to the number of full years of such term,

VOTING OF SENIOR NOTE MORTGAGE BONDS HELD BY SENIOR NOTE TRUSTEE
 
    Prior to the Release Date, the Senior Note Trustee, as a holder of Senior
Note Mortgage Bonds, will attend any meeting of bondholders under the First
Mortgage Indenture as to which it receives due notice, or, at its option, will
deliver its proxy in connection therewith. Either at such meeting, or otherwise
where the consent of holders of first mortgage bonds issued under the First
Mortgage Indenture is sought without a meeting, the Senior Note Trustee will
vote all of the Senior Note Mortgage Bonds held by it, or will consent or
withhold its consent with respect thereto, as directed by the holders of a
majority in aggregate principal amount of the outstanding Senior Notes;
provided, however, the Senior Note Trustee may not vote the Senior Note Mortgage
Bonds of any particular series in favor of, or give consent to, any action
which, in the Senior Note Trustee's opinion, would materially adversely affect
such series of Senior Note Mortgage Bonds in a manner not shared generally by
all other Senior Note Mortgage Bonds, except upon notification by the Senior
Note Trustee to the holders of the related series of Senior Notes of such
proposal and consent thereto of the holders of a majority in principal amount of
the outstanding Senior Notes of such series. (Section 4.03)
 
RESIGNATION OR REMOVAL OF NOTE TRUSTEE
 
    The Senior Note Trustee may resign at any time upon written notice to the
Company specifying the day upon which the resignation is to take effect and such
resignation will take effect immediately upon the later of the appointment of a
successor Senior Note Trustee and such specified day. (Section 9.10)
 
    The Senior Note Trustee may be removed at any time by an instrument or
concurrent instruments in writing filed with the Senior Note Trustee and signed
by the holders, or their attorneys-in-fact, of at least a majority in principal
amount of the then outstanding Senior Notes. In addition, so long as no event of
default or event which, with the giving of notice or lapse of time or both,
would become an event of default has occurred and is continuing, the Company may
remove the Senior Note Trustee upon notice to the holder of each Senior Note
outstanding and the Senior Note Trustee, and appointment of a successor Senior
Note Trustee. (Section 9.10)
 
CONCERNING THE SENIOR NOTE TRUSTEE
 
    The Bank of New York is the Senior Note Trustee under the Senior Note
Indenture. The Company maintains banking relationships with the Senior Note
Trustee in the ordinary course of business. The Senior Note Trustee also acts as
trustee for the Company's First Mortgage Bonds and as issuing and paying agent
for medium-term notes of Enogex.

               FIRST MORTGAGE BONDS AND FIRST MORTGAGE INDENTURE
 
GENERAL
 
    Any series of Senior Note Mortgage Bonds issued as security for Senior Notes
prior to the Release Date will be a series of First Mortgage Bonds issued under
the Trust Indenture dated February 1, 1945 as heretofore supplemented and
amended by supplemental trust indentures and a new supplemental trust indenture
for such series of Senior Note Mortgage Bonds (the "New Supplemental
Indenture"), all from the Company to The Bank of New York, as successor Trustee
(the "First Mortgage Trustee") to Boatmen's First National Bank of Oklahoma and
to the First National Bank and Trust Company of Oklahoma City (such Trust
Indenture, as supplemented and as to be supplemented, is herein referred to as
the "First Mortgage Indenture"). Copies of the First Mortgage Indenture, the
supplemental indentures and the form of the New Supplemental Indenture are filed
as exhibits to the Registration Statement of which this Prospectus is a part.
The following summaries of certain provisions of the First Mortgage Indenture do
not purport to be complete and are subject to, and qualified in their entirety
by, the detailed provisions of the First Mortgage Indenture which are
incorporated herein by this reference. References to Article and Section numbers
under this caption are references to Article and Section numbers of the First
Mortgage Indenture unless otherwise indicated. Unless the context indicates
otherwise, words or phrases defined in the First Mortgage Indenture are
capitalized and used with the same meanings herein. As of January 31, 1998,
seven series of First Mortgage Bonds in an aggregate principal amount of $557.5
million were outstanding under the First Mortgage Indenture, including four
series of Senior Note Mortgage Bonds in an aggregate principal amount of $470
million issued as security for the Prior Senior Notes.
 
TERMS OF SENIOR NOTE MORTGAGE BONDS
 
    Prior to the Release Date and upon the issuance of a series of Senior Notes
(including New Notes), a series of Senior Note Mortgage Bonds will be issued and
delivered to the Senior Note Trustee in an aggregate principal amount equal to
the aggregate principal amount of such series of Senior Notes and with the same
stated rate or rates of interest (or interest calculated in the same manner),
interest payment dates, stated maturity date and redemption provisions as such
series of Senior Notes. The Company's obligations to make payments with respect
to the principal of, premium, if any, and/or interest on a series of Senior Note
Mortgage Bonds shall be fully or partially, as the case may be, discharged to
the extent that, at the time that any such payment shall be due, the then due
principal of, premium, if any, and/or interest on the related series of Senior
Notes shall have been fully or partially paid or there shall have been deposited
with the Senior Note Trustee pursuant to the Senior Note Indenture sufficient
funds to fully or partially pay the then due principal, premium, if any, and/or
interest on such series of Senior Notes.
 
SECURITY FOR SENIOR NOTE MORTGAGE BONDS
 
    In the opinions of counsel for the Company, the Senior Note Mortgage Bonds,
if and when issued, will be secured by the First Mortgage Indenture, which
constitutes a first mortgage lien, subject only to Permissible Encumbrances,
upon all the property of the Company (except as summarized in the following
paragraph) for the equal pro rata security of each series of First Mortgage
Bonds, subject to the provisions related to any sinking fund or similar fund for
the benefit of First Mortgage Bonds of any particular series. The opinion does
not cover title to easements or rights-of-way as counsel believes the expense of
examination would exceed the cost of acquiring, by condemnation or purchase, any
easements or rights-of-way held under defective titles.
 
    There are excepted from the lien of the First Mortgage Indenture certain
securities, cash, contracts, receivables, motor vehicles, merchandise, equipment
and supplies, and certain non-utility real property. (Granting Clause of the
First Mortgage Indenture).
 
    The First Mortgage Indenture contains provisions for subjecting to the lien
thereof (subject to the limitations in Article XV in the case of consolidation
or merger) all property acquired by the Company after the date of the First
Mortgage Indenture other than property of the kind mentioned in the preceding
 
                                       12
<PAGE>
paragraph. (Granting Clause of the First Mortgage Indenture) Such provisions
might not be effective as to property acquired within the 90-day period
immediately preceding or acquired subsequent to the filing of a case with
respect to the Company under the United States Bankruptcy Code.
 
MAINTENANCE PROVISIONS
 
    As a Maintenance Fund for the First Mortgage Bonds, the Company covenants to
pay to the First Mortgage Trustee annually on May 1 an amount equal to 15% of
its Gross Operating Revenues for the preceding calendar year, after deducting
from such revenues (i) cost of electricity purchased for resale and (ii) rentals
paid for utility property, less credits at the Company's option for (a)
maintenance, (b) property retirements offset by Permanent Additions, (c)
retirements of First Mortgage Bonds, (d) Amounts of Established Permanent
Additions and (e) 15% of the portion of Gross Operating Revenues during such
calendar year attributable to increases since January 6, 1975, in the Company's
cost of fuel used in electric generation. Withdrawals from the Maintenance Fund
may be made on the basis of retirements of First Mortgage Bonds and Amounts of
Established Permanent Additions, but cash in excess of $100,000 remaining on
deposit in the Maintenance Fund for more than two years must be used for the
retirement of First Mortgage Bonds. Any such retirement through redemption would
be at the applicable regular redemption price of the First Mortgage Bonds to be
redeemed and subject to any restriction on the redemption of such First Mortgage
Bonds. (Article IX, Section 3.03 of Supplemental Indenture dated March 1, 1952,
and Section 1.01 of Supplemental Indenture dated September 14, 1976)
 
    The Company has covenanted to maintain its properties in adequate repair,
working order and condition. The First Mortgage Indenture contains provisions
for a periodic inspection of the Company's properties and report by an
independent engineer as to compliance with this covenant. (Section 8.06)
 
SINKING FUND PROVISIONS
 
    As an annual sinking fund for each series of First Mortgage Bonds, the
Company covenants to pay to the First Mortgage Trustee annually on December 1 an
amount sufficient to redeem, on the following February 1, for sinking fund
purposes, 1 1/4% of the highest principal amount at any time outstanding of
First Mortgage Bonds of the series for which the sinking fund is applicable.
Sinking fund payments may be offset by (a) application of Amounts of Established
Permanent Additions equal to 166 2/3% of the principal amount of First Mortgage
Bonds which would otherwise be required to be retired by the sinking fund and
(b) retirement or delivery to the First Mortgage Trustee of First Mortgage Bonds
of the series for which the sinking fund is applicable. The First Mortgage
Trustee is required to apply sinking fund money to the purchase or redemption of
First Mortgage Bonds of the series for which such funds are applicable. (Article
XII and Section 3.01 of Supplemental Indenture dated February 1, 1980)
 
ISSUANCE OF ADDITIONAL BONDS
 
    Additional First Mortgage Bonds secured by the First Mortgage Indenture may
be issued on the basis of (a) 60% of the Cost or Fair Value, whichever is less,
of net Permanent Additions (which become available upon proper certification by
the Company), after making the required deductions on account of Retired
Property (Article V); (b) an equal principal amount of retired First Mortgage
Bonds, the retirement whereof has not been otherwise used under the First
Mortgage Indenture (Article VI); and (c) deposit of an equal amount of cash with
the First Mortgage Trustee, which cash may be withdrawn by applying Amounts of
Established Permanent Additions equal to 166 2/3% of such cash to be withdrawn
or by retirement of First Mortgage Bonds. (Article VII and Section 3.04 of
Supplemental Indenture dated March 1, 1952) No additional First Mortgage Bonds
may be issued on basis (a), basis (b) under specified conditions or basis (c),
unless the Earnings Applicable to Bond Interest for a specified twelve-month
period are equal to twice the annual interest requirements on the First Mortgage
Bonds including those about to be issued. (Sections 5.03, 6.01 and 7.01)
Earnings Applicable to Bond Interest for the twelve months ended December 31,
1997, were 5.6 times the annual interest requirement on the First Mortgage Bonds
of the Company. Additional First Mortgage Bonds may vary from the New Bonds as
to maturity,
 
                                       13
<PAGE>
interest rate, redemption prices, sinking fund and in certain other respects.
(Article II) Any Senior Note Mortgage Bonds issued will be issued under (a)
and/or (b) above. At December 31, 1997, the amount of net Permanent Additions
which may be used for the issuance of First Mortgage Bonds exceeded $1.2
billion. At December 31, 1997, the amount of retired First Mortgage Bonds which
may be used for the issuance of First Mortgage Bonds was $299 million.
 
PROVISIONS OF FIRST MORTGAGE INDENTURE LIMITING DIVIDENDS ON COMMON STOCK
 
    The Company covenants that, so long as any First Mortgage Bonds are
outstanding, earned surplus (retained earnings) equal to the sum of (1) the
amount by which the aggregate of (a) provisions for retirement and depreciation
and (b) expenditures for maintenance, during the period from June 1, 1955, to
the last date for which a statement of income is available, is less than 15% of
Gross Operating Revenues (after deducting cost of electricity and/or gas
purchased for resale, rentals paid for utility property and the portion of gross
operating revenues attributable to increases since January 6, 1975, in the
Company's cost of fuel used in electric generation) for that period and (2) the
amount, if any, by which all of the consideration paid by the Company in
acquiring any shares of its Common Stock during the above period exceeds
$217,301,128 plus any consideration received by the Company from the sale after
September 30, 1991 of its Common Stock, shall not be available for the payment
of cash dividends on Common Stock; and that the Company shall not acquire shares
of its Common Stock for a valuable consideration if after such acquisition the
sum of (1) and (2) above would exceed its then earned surplus (retained
earnings). (Section 3.01 of Supplemental Indenture dated January 1, 1957,
Section 1.01 of Supplemental Indenture dated September 14, 1976 and Section 1.01
of Supplemental Indenture dated December 9, 1991)
 
RELEASE PROVISIONS
 
    The First Mortgage Indenture contains provisions permitting the release from
its lien of any property upon depositing or pledging cash or certain other
property of comparable Fair Value (Fair Value being defined in substance as the
current value of the property as certified by an engineer, appraiser or similar
expert). The First Mortgage Indenture also contains provisions for the
cancellation, change or alteration of leases, rights-of-way and easements, and
for the surrender and modification of any franchise or governmental consent
subject to certain restrictions, in each case without any release or consent by
the First Mortgage Trustee or accountability thereto for any consideration
received by the Company. (Article XI)
 
MODIFICATION OF THE FIRST MORTGAGE INDENTURE
 
    With the consent of the Company, the provisions of the First Mortgage
Indenture may be changed by the affirmative vote of the holders of 70% in
principal amount of the First Mortgage Bonds then outstanding except, among
other things, the maturity of a First Mortgage Bond may not be extended, the
interest rate reduced nor the terms of payment of principal or interest changed
without the consent of the holder of such First Mortgage Bond. (Article XVIII)
 
CONCERNING THE FIRST MORTGAGE TRUSTEE
 
    The Bank of New York is the First Mortgage Trustee under the First Mortgage
Indenture. The Company maintains banking relationships in the ordinary course of
business with the First Mortgage Trustee. The First Mortgage Trustee also serves
as trustee for the Senior Notes and as issuing and paying agent for medium-term
notes of Enogex.
 
    In case of a Completed Default under the First Mortgage Indenture (see
"--Events of Default" below), the First Mortgage Trustee may, and upon request
of the holders of a majority in principal amount of the First Mortgage Bonds
shall, declare the First Mortgage Bonds due and payable. In case of a Completed
Default, it is obligatory upon the First Mortgage Trustee to take the action or
actions provided in the First Mortgage Indenture to enforce payment of the First
Mortgage Bonds and for the enforcement of the lien of the First Mortgage
Indenture upon being requested to do so by the holders of a majority in
 
                                       14
<PAGE>
principal amount of the First Mortgage Bonds and upon being indemnified against
the costs, expenses and liabilities to be incurred therein or thereby without
negligence or bad faith. (Sections 13.01, 13.04 and 13.15)
 
EVENTS OF DEFAULT
 
    The following is a summary of events defined in the First Mortgage Indenture
as "Completed Defaults": (a) failure to pay principal of any First Mortgage Bond
when due and payable, (b) failure to pay interest on any First Mortgage Bond
within 30 days after it becomes due and payable, (c) failure to meet any payment
to the sinking fund on any First Mortgage Bond within 10 days after same is
payable, (d) the expiration of 30 days after (1) the adjudication of the Company
as a bankrupt or (2) the entry of an order approving a petition filed against
the Company seeking reorganization of the Company, unless during such period
such adjudication or order shall be vacated, (e) the expiration of 90 days
following the appointment of a receiver unless during such period such
appointment shall be vacated, (f) the filing by the Company of a voluntary
petition in bankruptcy or the making of a general assignment for the benefit of
creditors or the consent by the Company to the appointment of a receiver or the
filing by the Company of a petition or answer seeking reorganization or the
filing by the Company of a petition to take advantage of any insolvency act and
(g) failure to perform any other covenant or agreement contained in the First
Mortgage Indenture or First Mortgage Bonds within 60 days following the mailing
by the First Mortgage Trustee or by the holders of at least 15% in principal
amount of the First Mortgage Bonds then Outstanding of a written demand that
such failure be cured. (Section 13.01 and Section 4.01 of Supplemental Indenture
dated February 1, 1980)
 
    The First Mortgage Trustee is required to give notice to bondholders (1)
within 90 days after the occurrence of a default known to the First Mortgage
Trustee within such period, or (2) if a default be not known to the First
Mortgage Trustee within such period, within 30 days after such default shall be
known to the First Mortgage Trustee, unless such default shall have been cured
before the giving of such notice; provided that, except in the case of a default
resulting from the failure to make any payment of principal of or interest on
any First Mortgage Bonds or to make any sinking fund or purchase fund payment,
the First Mortgage Trustee may withhold such notice upon determination in good
faith by the board of directors, the executive committee or a trust committee of
directors and/or responsible officers of the First Mortgage Trustee that the
withholding of such notice is in the interest of the bondholders. (Section
16.07)

<PAGE>
                               BOOK-ENTRY SYSTEM
 
    Each series of New Notes may be issued in the form of one or more Global
Securities representing all or part of such series of New Notes and which will
be deposited with or on behalf of the Depository and registered in the name of
the Depository or a nominee of the Depository.
 
    The following is based solely on information furnished by DTC:
 
    Unless otherwise specified in the applicable Prospectus Supplement, DTC will
act as Depository for those New Notes issued as Global Securities. The Global
Securities will be issued as fully-registered securities registered in the name
of Cede & Co. (DTC's partnership nominee). DTC is a limited-purpose trust
company organized under the New York Banking Law, a "banking organization"
within the meaning of the New York Banking Law, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the New York Uniform
Commercial Code, and a "clearing agency" registered pursuant to the provisions
of Section 17A of the Exchange Act. DTC holds securities that its participants
("Participants") deposit with DTC. DTC also facilitates the settlement among
Participants of securities transactions, such as transfers and pledges, in
deposited securities through electronic computerized book-entry changes in
Participants' accounts, thereby eliminating the need for physical movement of
securities certificates. "Direct Participants" include securities brokers and
dealers, banks, trust companies, clearing corporations, and certain other
organizations. DTC is owned by a number of its Direct Participants and by the
New York Stock Exchange, Inc., the American Stock Exchange, Inc., and the
National Association of Securities Dealers, Inc. Access to the DTC system is
also available to others such as securities brokers and dealers, banks, and
trust companies that clear through or maintain a custodial relationship with a
Direct Participant, either directly or indirectly ("Indirect Participants"). The
rules applicable to DTC and its Participants are on file with the Commission.
 
    Purchases of New Notes under the DTC system must be made by or through
Direct Participants, which will receive a credit for the New Notes on DTC's
records. The ownership interest of each actual purchaser of each New Note
("Beneficial Owner") is in turn to be recorded on the Direct and Indirect
Participants' records. Beneficial Owners will not receive written confirmation
from DTC of their purchase, but Beneficial Owners are expected to receive
written confirmation providing details of the transaction, as well as periodic
statements of their holdings, from the Direct or Indirect Participant through
which the Beneficial Owner entered into the transaction. Transfers of ownership
interests in the New Notes are to be accomplished by entries made on the books
of Participants acting on behalf of Beneficial Owners. Beneficial Owners will
not receive certificates representing their ownership interests in the New
Notes, except in the event that use of the book-entry system for the New Notes
is discontinued.
 
    To facilitate subsequent transfers, all New Notes deposited by Participants
with DTC are registered in the name of DTC's partnership nominee, Cede & Co. The
deposit of the New Notes with DTC and their registration in the name of Cede &
Co. effect no change in beneficial ownership. DTC has no knowledge of the actual
Beneficial Owners of the New Notes so deposited; DTC's records reflect only the
identity of the Direct Participants to whose accounts such New Notes are
credited, which may or may not be the Beneficial Owners. The Participants will
remain responsible for keeping account of the holdings on behalf of their
customers.
 
    Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants or Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.
 
    If the Global Securities are redeemable, redemption notices shall be sent to
Cede & Co. If less than all of the Global Securities are being redeemed, DTC's
practice is to determine by lot the amount of the interest of each Direct
Participant in such issue to be redeemed.
 
    Neither DTC nor Cede & Co. will consent or vote with respect to the New
Notes. Under its usual procedures, DTC mails an Omnibus Proxy to the Company as
soon as possible after the record date. The
 
                                       16
<PAGE>
Omnibus Proxy assigns Cede & Co.'s consenting or voting rights to those Direct
Participants to whose accounts the New Notes are credited on the record date
(identified in a listing attached to the Omnibus Proxy).
 
    Principal, interest and any premium payments on the New Notes will be made
to DTC. DTC's practice is to credit Direct Participants' accounts on the payable
date in accordance with their respective holdings shown on DTC's records unless
DTC has reason to believe that it will not receive payment on such payable date.
Payments by Participants to Beneficial Owners will be governed by standing
instructions and customary practices, as in the case with securities held for
the accounts of customers in bearer form or registered in "street name," and
will be the responsibility of such Participant and not of DTC, the Senior Note
Trustee or the Company, subject to any statutory or regulatory requirements as
may be in effect from time to time. Payment of principal, interest and any
premium to DTC is the responsibility of the Company or the Senior Note Trustee,
disbursement of such payments to Direct Participants shall be the responsibility
of DTC, and disbursement of such payments to the Beneficial Owners shall be the
responsibility of Direct and Indirect Participants.
 
    DTC may discontinue providing its services as securities depository with
respect to a series of New Notes at any time by giving reasonable notice to the
Company or the Senior Note Trustee. Under such circumstances, if a successor
securities depository is not obtained, certificates for such series of New Notes
are required to be printed and delivered.
 
    The Company may decide to discontinue use of the system of book-entry
transfers through DTC (or a successor securities depository) for any series of
New Notes. In that event, certificates for such series of New Notes will be
printed and delivered.
 
    The information in this section concerning DTC and DTC's book-entry system
has been obtained from DTC, and the Company and any underwriters, dealers or
agents take no responsibility for the accuracy thereof.
 
    The underwriters, dealers or agents of any Offered Notes may be Direct
Participants of DTC.
 
    NONE OF THE COMPANY, THE SENIOR NOTE TRUSTEE, THE FIRST MORTGAGE TRUSTEE, OR
ANY AGENT FOR PAYMENT ON OR REGISTRATION OF TRANSFER OR EXCHANGE OF THE GLOBAL
SECURITY WILL HAVE ANY RESPONSIBILITY OR LIABILITY FOR ANY ASPECT OF THE RECORDS
RELATING TO OR PAYMENTS MADE ON ACCOUNT OF BENEFICIAL INTERESTS IN SUCH GLOBAL
SECURITY OR FOR MAINTAINING, SUPERVISING OR REVIEWING ANY RECORDS RELATING TO
SUCH BENEFICIAL INTERESTS.
 
                                 LEGAL OPINIONS
 
    Legal opinions relating to the New Notes will be rendered by Rainey, Ross,
Rice & Binns, Oklahoma City, Oklahoma, Chisenhall, Nestrud & Julian, P.A.,
Little Rock, Arkansas, and Gardner, Carton & Douglas, Chicago, Illinois, counsel
for the Company, and by Jones, Day, Reavis & Pogue, Chicago, Illinois, counsel
for any underwriters, dealers or agents named in the Prospectus Supplement. As
to matters involving conformity to local laws, the other counsel will rely upon
the opinion of Rainey, Ross, Rice & Binns with respect to laws of Oklahoma and
upon the opinion of Chisenhall, Nestrud & Julian, P.A., with respect to laws of
Arkansas.
 
    The statement contained in this Prospectus under the subcaption "Security
for Senior Note Mortgage Bonds" under the caption "FIRST MORTGAGE BONDS AND
FIRST MORTGAGE INDENTURE" is the opinion of Rainey, Ross, Rice & Binns, counsel
for the Company, to the extent that such statement pertains to Oklahoma law and
is the opinion of Chisenhall, Nestrud & Julian, P.A., to the extent that such
statement pertains to Arkansas law. As of December 31, 1997, attorneys with
Rainey, Ross, Rice & Binns owned beneficial interests in an aggregate of 5,259
shares of Common Stock of OGE Energy, of which Mr. William J. Ross, a partner in
that firm, owned a beneficial interest in 4,659 shares of such Common Stock.

                                    EXPERTS
 
    The consolidated financial statements and schedule of the Company included
in the Company's Form 10-K Annual Report for the fiscal year ended December 31,
1996, to the extent and for the periods indicated in their reports included in
said Form 10-K, have been audited by Arthur Andersen LLP, independent public
accountants, as indicated in their reports with respect thereto, and are
incorporated by reference herein in reliance upon the authority of said firm as
experts in accounting and auditing in giving said reports.
 
                              PLAN OF DISTRIBUTION
 
    The New Notes may be sold (i) through underwriters or dealers; (ii) directly
to one or more institutional purchasers; or (iii) through agents. The Prospectus
Supplement with respect to each series of New Notes will set forth the terms of
the offering of such New Notes, including the name or names of any underwriters,
the purchase price of such New Notes and the proceeds to the Company from such
sale, any underwriting discounts and other items constituting underwriters'
compensation, any initial public offering price, any discounts or concessions
allowed or reallowed or paid to dealers and any securities exchanges on which
said New Notes may be listed.
 
    If underwriters are used in the sale, the New Notes will be acquired by the
underwriters for their own account and may be resold from time to time in one or
more transactions, including negotiated transactions, at a fixed public offering
price or at varying prices determined at the time of sale. The New Notes may be
offered to the public either through underwriting syndicates represented by one
or more managing underwriters or directly by one or more of such firms. The
specific managing underwriter or underwriters, if any, will be set forth in the
Prospectus Supplement relating to the New Notes together with the members of the
underwriting syndicate, if any. Unless otherwise set forth in the applicable
Prospectus Supplement, the obligations of the underwriters to purchase the New
Notes offered thereby will be subject to certain conditions precedent and the
underwriters will be obligated to purchase all such New Notes if any are
purchased.
 
    New Notes may be sold directly by the Company or through agents designated
by the Company from time to time. The Prospectus Supplement will set forth the
name of any agent involved in the offer or sale of the New Notes in respect of
which the Prospectus Supplement is delivered and any commission payable by the
Company to such agent. Unless otherwise indicated in the applicable Prospectus
Supplement, any such agent is acting on a best efforts basis for the period of
its appointment.
 
    Any underwriters, dealers or agents participating in the distribution of the
New Notes may be deemed to be underwriters and any discounts or commissions
received by them on the sale or resale of the New Notes may be deemed to be
underwriting discounts and commissions under the Securities Act of 1933, as
amended. Agents and underwriters may be entitled, under agreements entered into
with the Company, to indemnification by the Company against certain civil
liabilities, including liabilities under the Securities Act of 1933, as amended,
and to contribution with respect to payments which the agents or underwriters
may be required to make in respect thereof. Agents and underwriters may engage
in transactions with or perform services for the Company in the ordinary course
of business.
 
    Any underwriter of New Notes issued prior to the Release Date may be
required under Oklahoma law to pay a mortgage registration tax in an amount
estimated by the Company to be .096% of the principal amount of New Notes
purchased.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Section 1031 of Title 18 of the Annotated Oklahoma Statutes provides that
the Company may, and in some circumstances must, indemnify the directors and
officers of the Company against liabilities and expenses incurred by any such
person by reason of the fact that such person was serving in such capacity,
subject to certain limitations and conditions set forth in the statute.
Substantially similar provisions that require such indemnification are contained
in the Company's Restated Certificate of Incorporation, which is filed as
Exhibit 4.01 to the Company's Registration Statement No. 33-59805, which is
incorporated herein by this reference. The Company's Restated Certificate of
Incorporation also contains provisions limiting the liability of the Company's
officers and directors in certain instances. The Company has an insurance policy
covering its directors and officers against certain personal liability which may
include liabilities under the Securities Act of 1933, as amended. The form of
Underwriting Agreement filed as Exhibit 1.01 includes provisions requiring the
underwriters to indemnify the directors and officers of the Company in certain
circumstances.

ITEM 17.  UNDERTAKINGS
 
    The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, as amended, each
filing of the Registrant's annual report pursuant to Section 13(a) or Section
15(d) of the Securities Exchange Act of 1934 that is incorporated by reference
in this Registration Statement shall be deemed to be a new registration
statement relating to the securities offered herein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 15 above, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by the controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
 
    The undersigned Registrant hereby also undertakes:
 
        (1) to file, during any period in which offers or sales are being made,
    a post-effective amendment to this Registration Statement:
 
        (i) to include any prospectus required by Section 10 (a) (3) of the
            Securities Act of 1933;
 
        (ii) to reflect in the prospectus any facts or event arising after the
             effective date of this Registration Statement (or the most recent
             post-effective amendment thereto) which, individually or in the
             aggregate, represent a fundamental change in the information set
             forth in this Registration Statement. Notwithstanding the
             foregoing, any increase or decrease in volume of securities offered
             (if the total dollar value of securities offered would not exceed
             that which was registered) and any deviation from the low or high
             end of the estimated maximum offering range may be reflected in the
             form of prospectus filed with the Commission pursuant to Rule
             424(b) if, in the aggregate, the changes in volume and price
             represent no more than a 20% change in the maximum aggregate
             offering price set forth in the "Calculation of Registration Fee"
             table in the effective registration statement; and
 
       (iii) to include any material information with respect to the plan of
             distribution not previously disclosed in this Registration
             Statement or any material change to such information in this
             Registration Statement;
 
provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Registrant pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in this Registration Statement.
 
        (2) that, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.
 
        (3) to remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.
 
                                      II-5
<PAGE>
        (4) that, for the purposes of determining any liability under the
    Securities Act of 1933:
 
        (i) The information omitted from the form of prospectus filed as part of
            this Registration Statement in reliance upon Rule 430A and contained
            in the form of prospectus filed by the Registrant pursuant to Rule
            424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed
            to be part of this Registration Statement as of the time it was
            declared effective.
 
        (ii) Each post-effective amendment that contains a form of prospectus
             shall be deemed to be a new Registration Statement relating to the
             securities offered therein, and the offering of such securities at
             that time shall be deemed to be the initial bona fide offering
             thereof.

                          OKLAHOMA GAS AND ELECTRIC COMPANY

                              (AN OKLAHOMA CORPORATION)

                             $                          

               SENIOR NOTES, SERIES DUE                       ,        


                                  PURCHASE AGREEMENT






To the Representatives of the several Underwriters
named in Schedule A hereto.   


Ladies and Gentlemen:

     Oklahoma Gas and Electric Company, an Oklahoma corporation (the 
"Company"), confirms its agreement with                                     
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                          
                     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 $                
                aggregate principal amount of the Company's Senior Notes, 
Series due                       ,         (the "Senior Notes"). The Senior 
Notes are to be issued pursuant to the Indenture dated as of October 1, 1995 
between the Company and The Bank of New York, as successor trustee (the 
"Trustee"), as heretofore amended and supplemented and as amended and 
supplemented by Supplemental Indenture No.       , dated as of                
     ,         , creating the series in which the Senior Notes are to be 
issued. The term "Indenture," as used herein, means such Indenture dated as 
of October 1, 1995, as so amended and supplemented, and includes

<PAGE>

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 The Bank of
New York, 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                     ,        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 $                                 of its          % Senior
Notes, Series due                       ,         (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] has been qualified under the Trust Indenture Act of
1939, as amended (the "1939 Act").

     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 333-             )
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

                                       2
<PAGE>

effective is referred to as the "Offering Terms."  Each prospectus used 
before such registration statement became effective, and any prospectus that 
omitted the Offering Terms, that was used after such effectiveness and prior 
to the execution and delivery of this Agreement, is herein called a 
"preliminary prospectus."  Such registration statement, including the 
exhibits thereto, schedules thereto, if any, and the documents incorporated 
by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, at 
the time it became effective and including the Offering Terms, is herein 
called the "Registration Statement."  Any registration statement filed 
pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as 
the "Rule 462(b) Registration Statement," and after such filing the term 
"Registration Statement" shall include the Rule 462(b) Registration 
Statement.  The final prospectus, including the documents incorporated by 
reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, in the 
form first furnished to the Underwriters for use in connection with the 
offering of the Senior Notes [and the Bonds] is herein called the 
"Prospectus."  If Rule 434 is relied on, the term "Prospectus" shall refer to 
the preliminary prospectus dated                              ,          
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             
              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 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.

                                       5
<PAGE>

             (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

                                       6
<PAGE>

     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 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

                                       7
<PAGE>

     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 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

                                       8
<PAGE>

     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.

     (b)     PAYMENT. Payment of the purchase price for, and delivery of 
certificates for, the Senior Notes shall be made at the offices of            
                                            , or at such other place as shall 
be agreed upon by the Representatives and the Company, at          .M. (      
                  time) on the fourth business day after the date hereof 
(unless postponed in accordance with the provisions of Section 11), or such 
other time not later than ten business days 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 
certificates for the Senior Notes to be purchased by them.  It is understood 
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.                             
     , 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.

     (c)     DENOMINATIONS; REGISTRATION. One certificate for the Senior 
Notes shall be in the amount of $                                  and 
registered in the name of Cede & Co., as nominee of the Depository Trust 
Company.  The Company will make the Senior Notes, which may be in temporary 
form, available for examination and packaging by the Representatives in       
                                         not later than             .M. (     
             time) on the business day prior to the Closing Time.

                                       9

[    (d)     PAYMENT OF OKLAHOMA REAL ESTATE MORTGAGE TAX. The Representatives
agree to deposit with the Company within two business days after the date of 
this Agreement the amount set forth in Schedule B hereto as the Oklahoma Real 
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.]

     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

                                       10
<PAGE>

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 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

                                       11
<PAGE>

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                              , in its 
sole discretion, directly or 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

conditions:

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

                                     and                                      
         , 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

                                       13
<PAGE>

             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;

                        (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;

                                       14
<PAGE>

                        (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] is 
             [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;

                        (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

                                       15
<PAGE>

             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 Indenture, as more fully set forth in the
             granting clauses thereof, (1) all shares of stock, bonds, notes,
             evidences of indebtedness and other securities other than such
             as may be or are required to be deposited from time to time with
             the First Mortgage Trustee, (2) cash other than such as may be or
             are required to be deposited from time to time with the 
             First Mortgage Trustee, (3) contracts, claims, bills and 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, equipment and supplies acquired for the purpose of
             sale or resale in the usual course of business or for the purpose
             of consumption in the operation, construction or repair of any of
             the properties of 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).]

             corporation and is in good standing under the laws of the State of
             Arkansas and has corporate power, right and authority to do 
             business and to own property in the State of Arkansas in the
             manner and as set forth in the Prospectus;

[                       (B)  the First Mortgage Indenture is in proper form, 
             conforming to the laws of the State of Arkansas, to give and create

             in Arkansas necessary to effectuate the lien of the First Mortgage
             Indenture;]

[                       (C)  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 Arkansas 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 Arkansas 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 Indenture,
             as more fully set forth in the granting clauses thereof, (1) all 
             shares of stock, bonds, notes, evidences of indebtedness and other
             securities other than such as may be or are required to be 
             deposited from time to time with the First Mortgage Trustee, 
             (2) cash other than such as may be or are required to be deposited
             from time to time with the First Mortgage Trustee, (3) contracts,
             claims, bills and accounts receivable, and choses in action other

             for the purpose of sale or resale in the usual course of business
             or for the purpose of consumption in the operation, construction
             or repair of any of the properties of 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 Arkansas and franchises from 
             Arkansas authorities now owned

                                       17

             lines);]

                        (D)  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 Arkansas as presently 
             conducted and as described in the Prospectus;

                        (E)  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;

             authorizing the issuance and sale by the Company of the Senior 
             Notes and the issuance of the Bonds on terms consistent with this
             Agreement and 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 the Arkansas Commission or any other 
             governmental 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 and delivery of the Senior Notes [and the issuance
             or delivery of the Bonds] by the Company to the Trustee as 
             contemplated in this Agreement; and

                        (G)  such counsel is not handling any litigation 
             relating to the Company except as set forth in a schedule attached
             to such opinion.

             Prospectus (except as to the financial

             1934 Act and the 1934 Act Regulations;

                        (D)  the Indenture [and the First Mortgage Indenture] 
             [have each] has been qualified under the 1939 Act as and to the 
             extent required by the provisions of the 1939 Act; and

             certificates or orders of any state or federal commission or 
             regulatory authority that are necessary with respect to the

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

delivering written notice of termination to the Representatives.  Any such 
termination shall be without liability of any party to any other party except

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

                                       21
<PAGE>

     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                 
                            ), 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                                     
expressly for use in the Registration Statement (or any amendment thereto), 
including the Offering Terms, or any preliminary prospectus or the Prospectus 
(or any amendment or supplement thereto), which information is set forth on 
Schedule C hereto.  The foregoing indemnity agreement is in addition to any 
liability which the Company may otherwise have to any Underwriter or to any 
controlling person of that Underwriter.

     (b)     INDEMNIFICATION OF COMPANY, DIRECTORS AND OFFICERS. Each 
Underwriter, severally and not jointly, agrees to indemnify and hold harmless 
the Company, its directors, each of its officers who signed the Registration 
Statement, and each person, if any, who controls the Company within the 
meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against 
any and all loss, liability, claim, damage and expense described in the 
indemnity contained in subsection (a) of this Section, as incurred, but only 
with respect to untrue statements or omissions, or alleged untrue statements 
or omissions, made in the Registration Statement (or any amendment thereto), 
including the Offering Terms, or any preliminary prospectus or the Prospectus 
(or any amendment or supplement thereto) in reliance upon and in conformity 
with the written information furnished to the Company by such Underwriter 
through                                    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.

                                       22

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

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

     SECTION 8. CONTRIBUTION

     If the indemnification provided for in Section 7 hereof is for any 
reason unavailable to or insufficient to hold harmless an indemnified party 
in respect of any losses, liabilities, claims, damages or expenses referred 
to therein, then each indemnifying party shall contribute to the aggregate 
amount of such losses, liabilities, claims, damages and expenses incurred by 
such indemnified party, as incurred, (i) in such proportion as is appropriate 
to reflect the relative benefits received by the Company on the one hand and 
the Underwriters on the other hand from the offering of the Senior Notes 
pursuant to this Agreement or (ii) if the allocation provided by

                                       23
<PAGE>

clause (i) is not permitted by applicable law, in such proportion as is 
appropriate to reflect not only the relative benefits referred to in clause 
(i) above but also the relative fault of the Company on the one hand and of 
the Underwriters on the other hand in connection with the statements or 
omissions which resulted in such losses, liabilities, claims, damages or 
expenses, as well as any other relevant equitable considerations.

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

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

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

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

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

     For purposes of this Section 8, each person, if any, who controls an 
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of 
the 1934 Act shall have the same

                                       24
<PAGE>

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.

     (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.

                                       25

     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 Representatives at attention of;

respective successors, and said controlling persons and officers and

Underwriter shall be deemed to be a successor by reason merely of such 
purchase.

thereof shall contain suitable provisions with respect to the matters  hereafter
specified  in this Section. The  bonds of said series  shall be substantially of
the tenor  and purport  hereinbefore recited.  The bonds  of said  series  shall
mature              , and shall be issued as registered bonds without coupons in
denominations of $1,000, and any multiple  of $1,000 and registered in the  name
of  the Senior Note Trustee. The bonds of said series shall bear interest at the
rate of     % per  annum payable semi-annually on          and          of  each
year.  The principal and interest  shall be payable to  the person in whose name
such Bond is registered at the office of the Trustee at Oklahoma City, Oklahoma,
in lawful money of the United States of America.
 
    The Company's obligation to make payments with respect to the principal  of,
premium  and/or interest on the Bonds of Senior  Note Series   shall be fully or
partially, as the case may be, satisfied  and discharged to the extent that,  at
the  time that any such payment shall be due, the then due principal of, premium
and/or interest on the Senior Notes due      shall have been fully or  partially
paid or there shall have been deposited with the Senior Note Trustee pursuant to
Section 2.12 of the Senior Note Indenture sufficient available funds to fully or
partially  pay the then  due principal, premium,  if any and/or  interest on the
Senior Notes due      . Bonds of Senior Note Series    shall be dated as of  the
interest  payment date next preceding the  authentication thereof by the Trustee
except that (i) if any such bond shall be authenticated before             ,  it

if  the Company shall at the time of the authentication of a Bond of Senior Note
Series   be in default in the payment of interest upon the Bonds of Senior  Note
Series    ,  such bonds shall  be dated as of  the date of  the beginning of the
period for which such interest is so in  default, and (iii) as long as there  is
no  existing default  in the  payment of  interest on  the Bonds  of Senior Note
Series   , if any Bond of Senior Note Series   shall be authenticated after  the
close  of business on  any Record Date but  on or prior  to the interest payment
date relating to such Record Date, it shall be dated as of such interest payment
date.

by redemption  [, purchase]  or otherwise,  or upon  provision for  the  payment
thereof  having been  made in  accordance with Section  5.01 of  the Senior Note
Indenture, Bonds of  Senior Note Series    in  a principal amount  equal to  the
principal  amount of the Senior Notes due     so paid or for which provision for
payment has been made shall be  deemed fully paid, satisfied and discharged  and
the  obligations of the Company thereunder shall be terminated and such Bonds of
Senior Note Series   shall be surrendered to and cancelled by the Trustee.  From
and  after such time as all bonds (other than  Bonds of Senior Note Series   and
bonds of  any other  series delivered  to the  Senior Note  Trustee pursuant  to
Section  4.09 of the  Senior Note Indenture) have  been retired through payment,
redemption or otherwise (including  those bonds "deemed to  be paid" within  the
meaning  of that term as used in Article X of the Original Indenture) at, before
or after the  maturity thereof (the  "Release Date"), the  Bonds of Senior  Note
Series   shall

be deemed fully paid, satisfied and discharged and the obligation of the Company
thereunder  shall be terminated. On  the Release Date, the  Bonds of Senior Note
Series   shall be surrendered to and cancelled by the Trustee.
 
    SECTION 2.03.  The terms and conditions of redemption of the Bonds of Senior
Note Series   need not  be specified in any Bond of  Senior Note Series   if  an
appropriate   reference  be  made  in  said  Bond  to  the  provisions  of  this
Supplemental Trust Indenture. [The terms and conditions for the repayment of the
Bonds of Senior Note Series       at the option  of the holder of any such  Bond
need  not be specified in the Bonds of Senior Note Series      if an appropriate
reference is made  in said  Bond to the  provisions of  this Supplemental  Trust
Indenture.]
 
    SECTION  2.04.  The  registered holder of  any Bond or  Bonds of Senior Note
Series   at his option may  surrender the same at the principal corporate  trust

cancellation, in exchange for other  Bonds of Senior Note Series    of the  same
aggregate  principal amount, bearing interest as provided in Section 2.09 of the
Original Indenture. Thereupon, and  upon receipt of  any payment required  under
the  provisions of Section 2.05 hereof, the Company shall execute and deliver to
the Trustee and the Trustee shall authenticate and deliver such other registered
bonds without coupons to such  registered holder at its  office or at any  other
place specified as aforesaid.
 
    SECTION  2.05.  No charge  shall be made by the  Company for any exchange or
transfer of Bonds  of Senior  Note Series     , other  than for  taxes or  other
governmental charges, if any, that may be imposed in relation thereto.
 
                                  ARTICLE III.
 
                  REDEMPTION OF BONDS OF SENIOR NOTE SERIES
 
    SECTION  3.01.  (a) Upon notice being given of the redemption of all or part
of the Senior Notes  due      in accordance with  the Senior Note Indenture  and
such  Senior Notes becoming  due and payable  in accordance with  such notice of
redemption, the Company shall  redeem on the redemption  date specified in  such
notice  a  principal amount  of  Bonds of  Senior  Note Series     equal  to the
principal amount of Senior Notes due      to be redeemed, at a redemption  price
equal  to the  principal amount  of such  Bonds of  Senior Note  Series    to be
redeemed, plus a premium equal to the premium payable on the redemption of  such
Senior Notes due     , plus accrued interest to such redemption date.
 
    (b)  In the  event the  principal of  all Senior  Notes is  declared due and
payable pursuant to Section 8.01(a) of  the Senior Note Indenture, the Bonds  of
Senior Note Series   shall be redeemable in whole upon receipt by the Trustee of
a written demand (hereinafter called a "Redemption Demand") from the Senior Note
Trustee  stating that there has been such declaration, stating that it is acting
pursuant to the  authorization granted  by Section  8.01(a) of  the Senior  Note
Indenture, and demanding redemption of all Senior Note First Mortgage Bonds on a
date  specified in such Redemption Demand  (the "Demand Redemption Date"), which
date shall not be less than 10 days nor more than 35 days after the date of  the
Redemption  Demand.  The  Trustee  shall, within  3  days  after  receiving such
Redemption Demand, mail  a copy thereof  to the Company  marked to indicate  the
date  of its receipt by the Trustee. Upon receipt by the Company of such copy of
a Redemption Demand, the Bonds of Senior Note Series   shall be redeemed by  the
Company on the Demand Redemption Date, upon surrender thereof by the Senior Note
Trustee  to the  Trustee, at  a redemption price  equal to  the principal amount
thereof, plus accrued interest  to the Demand Redemption  Date. If a  Redemption
Demand  is rescinded by the Senior Note Trustee by written notice to the Trustee
prior to  the Demand  Redemption Date,  the Company  shall not  be obligated  to
redeem  the Bonds of Senior Note Series    on the Demand Redemption Date; but no
such rescission shall  extend to or  affect any subsequent  acceleration of  the
Senior Notes or impair any right consequent thereon.

    [(c)  In the event that one or more holders of Senior Notes due     properly
elect to have  all or a  portion of  the outstanding principal  amount of  their
Senior  Notes due     repurchased by the Company on           in accordance with
the Senior Note Indenture so that such principal amount of Senior Notes due
becomes due and payable on            under the Senior Note Indenture, then  the
Company  shall repurchase on              a principal amount  of Bonds of Senior
Notes Series  equal to  the principal  amount of  Senior Notes  due       to  be
repurchased  on      at a price  equal to the principal  amount of such Bonds of
Senior Note Series to be repurchased, plus accrued interest to such date.
 
    SECTION 3.02.   The Company  covenants that,  for so  long as  any Bonds  of
Senior  Note Series    are outstanding, it will  take appropriate action so that
Bonds of Senior  Note Series    are not  redeemed or purchased  pursuant to  the
Sinking Fund requirement provided for in Article XII of the Original Indenture.
 
    SECTION  3.03.  Redemption [or  purchase] of Bonds of Senior  Note Series
shall be effected, without further notice by the Company or the Trustee, by  the
payment  by the Company of the applicable price specified in Section 3.01 hereof
at the place  specified for payment  of the  principal of and  interest on  such
bonds.
 
    SECTION  3.04.  The Company covenants and  agrees that, prior to the Release
Date, it will not take any action (except as required by Section 3.01(b) hereof)
that would cause the  outstanding principal amount of  the Bonds of Senior  Note
Series    to  be less than the  then outstanding principal  amount of the Senior
Notes due     .

portion of the Senior Note due      to be repaid) will be permitted after
exercise of the repayment option.  The repayment option may be exercised by the
Holder of a Senior Note due      for less than the entire principal amount of
the Senior Note due     , provided the principal amount which is to be repaid
is set forth on the form entitled "Option to Elect Repayment" on the Senior
Note due      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 Senior Note due      for repayment will be determined by the
Company, whose determination will be final, binding and non-appealable.  Upon
timely delivery of a Senior Note due      to the Trustee with the "Option to
Elect Repayment" form completed in accordance with the foregoing, the
outstanding principal amount of such Senior Note due      (or portion thereof
indicated on the "Option to Elect Repayment") shall become due and payable on
        , at a price equal to    % of the principal amount to be repaid plus
accrued and unpaid interest to           .]

     SECTION 2.07   The Senior Notes due      shall be issued in fully
registered form without coupons in denominations of $1,000 and integral
multiples thereof.

     SECTION 3.01

     [(a) From and after the Release Date and so long as any Senior Notes due
     are outstanding, the Company will not issue, assume or guarantee any Debt
secured by any mortgage, security interest, pledge or lien (herein referred to
as a "mortgage") of or upon any Operating Property of the Company, whether
owned at the date of the Indenture or thereafter acquired, and will not permit
to exist any Debt secured by a mortgage on any Operating Property created on or
prior to the Release Date, without in any such case effectively securing, on
the later to occur of the issuance, assumption or guaranty of any such Debt or
the Release Date, the outstanding Senior Notes due      (together with, if the
Company shall so determine, any other Notes or indebtedness or obligation of or
guaranteed by the Company ranking senior to, or equally with, the Notes and
then existing or thereafter created) equally and ratably with such Debt;
provided, however, that the foregoing restriction shall not apply to Debt
secured by any of the following:

     (1)  mortgages on any property existing at the time of acquisition
thereof;

     (2)  mortgages on property of a corporation existing at the time such
corporation is merged into or consolidated with the Company, or at the time of
a sale, lease or other disposition of the properties of such corporation or a
division thereof as an entirety or substantially as an entirety to the Company,
provided that such mortgage as a result of such merger, consolidation, sale,
lease or other disposition is not extended to property owned by the Company
immediately prior thereto;

     (3)  mortgages on property to secure all or part of the cost of acquiring,
substantially repairing or altering, constructing, developing or substantially
improving such property, or to secure indebtedness incurred to provide funds
for any such purpose or for reimbursement of funds previously expended for any
such purpose, provided such mortgages are created or assumed contemporaneously
with, or within 18 months after, such acquisition or completion of substantial
repair or alteration, construction, development or substantial improvement or
within six months thereafter pursuant to a commitment for financing arranged
with a lender or investor within such 18 month period;

     (4)  mortgages in favor of the United States of America or any State
thereof, or any department, agency or instrumentality or political subdivision
of the United States of America or any state thereof, or for the benefit of
holders of securities issued by any such entity, to secure any Debt incurred
for the purpose of financing all or any part of the purchase price or the cost
of substantially repairing or altering, constructing, developing or
substantially improving the property subject to such mortgages; or

     (5)  any extension, renewal or replacement (or successive extensions,
renewals or replacements), in whole or in part, of any mortgage referred to in
the foregoing clauses (1) to (4), inclusive; provided, however, that the
principal amount of indebtedness secured thereby and not

                                      5
<PAGE>

otherwise authorized by said clauses (1) to (4), inclusive, shall not exceed 
the principal amount of indebtedness, plus any premium or fee payable in 
connection with any such extension, renewal or replacement, so secured at the 
time of such extension, renewal or replacement.

     (b)  Notwithstanding the provisions of Section 3.01(a), from and after 
the Release Date and so long as any Senior Notes due                         
are outstanding, the Company may issue, assume or guarantee Debt, or permit 
to exist Debt, secured by mortgages which would otherwise be subject to the 
restrictions of Section 3.01(a) up to an aggregate principal amount that, 
together with the principal amount of all other Debt of the Company secured 
by mortgages (other than mortgages permitted by Section 3.01(a) that would 
otherwise be subject to the foregoing restrictions) and the Value of all Sale 
and Lease-Back Transactions in existence at such time (other than any Sale 
and Lease-Back Transaction that, if such Sale and Lease-Back Transaction had 
been a mortgage, would have been permitted by Section 3.01(a), other than 
Sale and Lease-Back Transactions permitted by Section 3.02 because the 
commitment by or on behalf of the purchaser was obtained no later than 18 
months after the later of events described in clause (i) or (ii) of Section 
3.02, and other than Sale and Lease-Back Transactions as to which application 
of amounts have been made in accordance with clause (z) of Section 3.02), 
does not at the time exceed the greater of 10% of Net Tangible Assets or 10% 
of Capitalization.

     (c)  If at any time the Company shall issue, assume or guarantee any Debt
secured by any mortgage and if Section 3.01(a) requires that the outstanding
Senior Notes due      be secured equally and ratably with such 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 contained in Section 3.01(a) has been
                complied with; and

           (2)  An Opinion of Counsel to the effect that such covenant
                has been complied with, and that any instruments executed
                by 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      equally and ratably with any other obligation or indebtedness
(including other Notes) pursuant to the provisions of this Section 3.01, 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.

     SECTION 3.02.  From and after the Release Date and so long as any Senior
Notes due      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 Operating Property if, in any
case, the commitment by or on behalf of the purchaser is obtained more than 18

                                      6
<PAGE>

months after the later of (i) the completion 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 improved, unless (x) the Company would
be entitled pursuant to Section 3.01(a) to issue, assume or guarantee Debt
secured by a mortgage on such Operating Property without equally and ratably
securing the Notes of this Series or (y) the Company would be entitled pursuant
to Section 3.01(b), after giving effect to such Sale and Lease-Back
Transaction, to incur $1.00 of additional Debt secured by mortgages (other than
mortgages permitted by Section 3.01(a)) or (z) the Company shall apply or cause
to be applied, in the case of a sale or transfer for cash, an amount equal to
the net proceeds thereof (but not in excess of the net book value of such
Operating Property at the date of such sale or transfer) and, in the case of a
sale or transfer otherwise than for cash, an 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 to the Trustee
for retirement and cancellation and (b) the principal amount, plus any premium
or fee paid in connection with any redemption in accordance with the terms of
other Debt voluntarily retired by the Company within such 180-day period,
excluding in each case retirements pursuant to mandatory sinking fund or
prepayment provisions and payments at maturity.

The interest so payable and punctually paid or duly provided for on any such

following the next succeeding Regular Record Date; and provided that interest 
payable on the Maturity Date set forth above or, if applicable, upon

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.

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.

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

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

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         , at a price equal
to     % of the principal amount to be repaid plus accrued and unpaid interest
to         .]

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

     The Company, at its option, and subject to the terms and conditions
provided in the Indenture, will be discharged from any and all obligations in
respect of the Notes (except for certain obligations including obligations to
register the transfer or exchange of Notes, replace stolen, lost or mutilated

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.

Oklahoma Gas and Electric Company

Oklahoma City, Oklahoma  73101

     RE:  $112,500,000 PRINCIPAL AMOUNT OF SECURITIES

Gentlemen:

     We have examined the Form S-3 Registration Statement, dated February 12, 
1998 (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 $112,500,000 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 The Bank of New York, as successor, as 
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 The Bank of New York, 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 purposes 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:

     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 legal, valid, 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.   When, as and if the Registration Statement on Form S-3, to which this
opinion is an exhibit, becomes effective pursuant to the provisions of the
Securities Act of 1933, as amended and the Oklahoma Corporation Commission has
authorized the issuance and sale of the Securities and (a) 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 (b) with respect to
the Bonds, when, as and if the Bonds and one or more New Supplemental Trust
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
