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 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 5,637,300 kilowatts. The Company's wholly-owned subsidiary, Enogex Inc., owns and operates more than 3,000 miles of natural gas transmission and gathering pipeline and, through its wholly-owned subsidiaries, has interests in four gas processing plants, markets natural gas and natural gas products and invests in the exploration and production of natural gas. (See "Restructuring" below.) The Company furnishes retail electric service in 270 communities and contiguous rural and suburban territories in Oklahoma and western Arkansas (population served estimated by the Company at 1,400,000). It also sells electric energy at wholesale for resale in six communities and to two 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 276 communities served, 247 are located in Oklahoma and 29 in Arkansas. Approximately 91% of the Company's electric operating revenues for the year ended December 31, 1994, was derived from sales in Oklahoma and approximately 9% from sales in Arkansas.

RESTRUCTURING

The Company has proposed a corporate restructuring (the "Restructuring") under which it will become the subsidiary of a newly-formed holding company (the "Holding Company"), and the Company's Common Stock will be exchanged on a share-for-share basis for Common Stock of the Holding Company. Following the Restructuring, Enogex Inc. will become a direct subsidiary of the Holding Company and will cease to be a subsidiary of the Company. The Company's Current Report on Form 8-K dated August 3, 1995, filed with the Securities and Exchange Commission (the "Commission") and incorporated by reference in this Prospectus, includes pro forma financial information for the Company as of June 30, 1995 and December 31, 1994, and for the six months ended June 30, 1995 and each of the three years in the period ended December 31, 1994, after giving effect to the Restructuring and the transfer by the Company of Enogex Inc. and its subsidiaries ("Enogex") to the Holding Company as if they had occurred on January 1, 1992. The Restructuring is subject to certain conditions, including shareowner approval and the receipt of regulatory approvals. The Securities and other outstanding indebtedness of the Company will not be transferred or exchanged in the Restructuring and, following the Restructuring, will remain direct obligations of the Company with the same terms as in effect immediately prior to the Restructuring.

The following documents, as filed by the Company with the Commission, are incorporated herein by reference: (i) Form 10-K Annual Report of the Company for the year ended December 31, 1994 as amended by the Form 10-K/A filed April 27, 1995 and the Form 10-K/A-2 filed May 22, 1995; (ii) Form 10-Q Quarterly Reports of the Company for the quarters ended March 31, 1995 and June 30, 1995 and (iii) Form 8-K Current Reports of the Company dated July 26, 1995 and August 3, 1995.

1.   Enogex's assets, liabilities,  equity and results  of operations have  been
     eliminated  from consolidated  Company amounts  to reflect  the transfer of
     ownership and control of Enogex from the Company to the Holding Company.
2.   After the transaction,  the Company  will not retain  ownership of  Enogex.
     Consequently, intercompany transactions between the Company and Enogex have
     not    been   eliminated   in   the   pro   forma   financial   statements.
     The most significant  intercompany transactions are  transmission fees  and
     related charges to the Company from Enogex, whose core business has been to
     transport  natural gas  to the  Company power  plants. The  amount of these
     charges were $44.6  million for the  12 months ended  June 30, 1995;  $44.8
     million  for the year ended  December 31, 1994; $54.9  million for the year
     ended December 31, 1993; and $55.0 million for the year ended December  31,
     1992.

SECURITIES

The Securities may be issued in one or more series as (i) first mortgage bonds or (ii) notes or debentures secured by the Company's first mortgage bonds or, in the circumstances described under the caption "DESCRIPTION OF SENIOR NOTES -- Security; Release Date," as unsecured notes or debentures (such notes and debentures are herein referred to as "Senior Notes"). From and after the Release Date (as defined below), any outstanding Senior Notes secured by the Company's first mortgage bonds when issued, will cease to be secured and will become unsecured general obligations of the Company. Senior Notes will be issued under an indenture (the "Senior Note Indenture"), the form of which is an exhibit to the Registration Statement, between the Company and Boatmen's First National Bank of Oklahoma, as trustee (the "Senior Note Trustee"), and are described below under the caption "DESCRIPTION OF SENIOR NOTES". First mortgage bonds (the "New Bonds") will 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 for each such series of New Bonds, all from the Company to Boatmen's First National Bank of Oklahoma, as successor trustee (such Trust Indenture, as supplemented and as to be supplemented, is herein referred to as the "First Mortgage Indenture"). The New Bonds are described below under the caption "FIRST MORTGAGE BONDS AND FIRST MORTGAGE INDENTURE."

There is no requirement, under either the Senior Note Indenture or the First Mortgage Indenture (collectively, the "Indentures"), that future issues of debt securities of the Company be issued under the Indentures, and the Company will be free to employ other indentures or documentation, containing provisions different from those included in the Indentures or applicable to one or more issues of Securities, in connection with future issues of such other debt securities.

DESCRIPTION OF SENIOR NOTES

GENERAL

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 incorporated herein by this reference and the form of which is an exhibit to the Registration Statement of which this Prospectus is a part. 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 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." FROM
AND AFTER THE RELEASE DATE, THE SENIOR NOTES WILL CEASE TO BE SECURED AS TO THE PAYMENT OF PRINCIPAL AND INTEREST, WILL BECOME UNSECURED GENERAL OBLIGATIONS OF THE COMPANY AND WILL RANK ON A PARITY WITH OTHER UNSECURED INDEBTEDNESS OF THE COMPANY. The Senior Note Indenture provides that, in addition to the Senior 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 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 June 30, 1995, the Company could issue more than $700 million of additional first mortgage bonds at an assumed 8.5% interest rate.

The Senior Note Indenture provides that the Senior 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 Senior Notes will specify: (1) the designation and aggregate principal amount of such Senior Notes; (2) the date on which such Senior Notes will mature; (3) the interest rate or rates, or method of calculation of such rate or rates, on such Senior 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

5

Senior Notes may be repaid, in whole or in part, at the option of the holder thereof; and (8) other specific terms applicable to such Senior Notes. Unless otherwise indicated in the applicable Prospectus Supplement, the Senior Notes will be denominated in United States currency in minimum denominations of $1,000 and integral multiples thereof, except that the denomination of any Senior Note issued in the form of a Global Security will not exceed $200,000,000 without the approval of the Depository.

Unless otherwise indicated in the applicable Prospectus Supplement, there are no provisions in the Senior Note Indenture or the Senior Notes that require the Company to redeem, or permit the holders to cause a redemption of, the Senior 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. (See "OKLAHOMA GAS AND ELECTRIC COMPANY -- Restructuring.") 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

Senior Notes of any series will be exchangeable for other Senior 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, Senior 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 Senior 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 being satisfied with the documents of title and indemnity of the person making the request. (Section 2.06 and 2.07)

In the event of any redemption of Senior Notes of any series, the Trustee will not be required to exchange or register a transfer of any Senior Notes of such series selected, called or being called for redemption except, in the case of any Senior 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 Senior 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 Senior Notes that are in the form of certificated securities will be paid by check mailed to the person entitled thereto at such person's address at it appears in the register for the Senior 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 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 and premium, if any, on Senior 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 Senior Note which remain unclaimed at the end of two years after such

6

principal, interest or premium shall have become due and payable will be repaid to the Company and the holder of such Senior Note will thereafter look only to the Company for payment thereof. (Section 5.04)

SECURITY; RELEASE DATE

Until the Release Date (as defined below), the Senior Notes 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 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 being issued. Payment by the Company to the Senior Note Trustee of principal of, premium 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 and interest on, the Senior Notes (Section 4.11). 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 (OTHER THAN SENIOR NOTE MORTGAGE BONDS) HAVE BEEN RETIRED (AT, BEFORE OR AFTER THE MATURITY THEREOF) THROUGH PAYMENT OR REDEMPTION (INCLUDING THOSE FIRST MORTGAGE BONDS DEEMED TO BE PAID WITHIN THE MEANING OF THE FIRST MORTGAGE INDENTURE). 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 OF THE OCCURRENCE OF THE RELEASE DATE. AS A RESULT, FROM AND AFTER THE RELEASE DATE, THE SENIOR NOTE MORTGAGE BONDS SHALL CEASE TO SECURE THE SENIOR NOTES, AND THE SENIOR 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 Senior Notes from issuing or assuming other secured debt, or incurring liens on its property, unless 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 and 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 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 or reorganization 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 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, the Senior Note Trustee is empowered to cause the mandatory redemption of the Senior Note Mortgage

7

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 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)

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 indemnity acceptable to the Senior Note Trustee. (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, with respect to the Senior Notes. (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 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 Senior Note Mortgage Bonds securing the Senior Notes to an amount less than the principal amount of the 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

8

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 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 OF ASSETS

The Company will not consolidate with or merge into any other corporation or sell, transfer or otherwise convey all or substantially all its assets unless the successor or transferee corporation assumes by supplemental indenture the due and punctual payment of the principal 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 conveyance 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 conveyance 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)

VOTING OF SENIOR NOTE MORTGAGE BONDS HELD BY SENIOR NOTE TRUSTEE

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 with respect thereto, as directed by the holders of not less than 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.

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-

9

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

Boatmen's First National Bank of Oklahoma 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.

FIRST MORTGAGE BONDS AND FIRST MORTGAGE INDENTURE

GENERAL

The New Bonds, including any series of Senior Note Mortgage Bonds issued as security for Senior Notes, will be a series of First Mortgage Bonds issued under the First Mortgage Indenture and a new supplemental trust indenture for such series of New Bonds (the "New Supplemental Indenture"), all from the Company to Boatmen's First National Bank of Oklahoma, as successor Trustee (the "First Mortgage Trustee") to The First National Bank and Trust Company of Oklahoma City. 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. Excluding the New Bonds, as of June 30, 1995, 13 series of First Mortgage Bonds in an aggregate principal amount of $653.5 million currently are outstanding under the First Mortgage Indenture.

TERMS OF NEW BONDS

The New Bonds will be issued initially as fully registered bonds in denominations of a multiple of $1,000 each. New Bonds may be issued in temporary form if, for any reason, the Company is unable to deliver New Bonds in definitive form. Principal and interest are to be payable in Oklahoma City, New York City or Chicago. The New Bonds will be interchangeable in the manner provided in Article II of the New Supplemental Indenture. No charge will be made for any exchange or transfer of New Bonds, other than for any taxes or other governmental charges.

Principal of and interest and premium, if any, on the New Bonds issued in the form of Global Securities will be paid in the manner described below under the caption "BOOK-ENTRY SYSTEM."

Reference is made to the applicable Prospectus Supplement for the following terms and other information with respect to the series of New Bonds being offered thereby: (1) the designation and aggregate principal amount of such New Bonds; (2) the date on which the New Bonds will mature; (3) the rate per annum (or method of calculation) at which such New Bonds will bear interest 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 New Bonds may be repaid, in whole or in part, at the option of the holder thereof; and (8) other specific terms applicable to New Bonds.

10

SECURITY FOR NEW BONDS

In the opinions of counsel for the Company, the New Bonds, 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 is not a lien on the properties of any subsidiary of the Company, nor is the stock of any such subsidiary pledged under 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 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

11

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 June 30, 1995, would be 4.4 times the annual interest requirement on the First Mortgage Bonds of the Company at an assumed 8.5% interest rate. Additional First Mortgage Bonds may vary from the New Bonds as to maturity, interest rate, redemption prices, sinking fund and in certain other respects. (Article II.) The New Bonds will be issued under (a) and/or (b) above. At June 30, 1995, the amount of net Permanent Additions which may be used for the issuance of First Mortgage Bonds was approximately $1.1 billion. At June 30, 1995, the amount of retired First Mortgage Bonds which may be used for the issuance of First Mortgage Bonds was $267 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.)

12

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

Boatmen's First National Bank of Oklahoma 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.

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 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.)

By Section 16.07 of the First Mortgage Indenture, 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.

13

BOOK-ENTRY SYSTEM

Each series of Securities may be issued in the form of one or more Global Securities representing all or part of such series of Securities 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.

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 Securities Exchange Act of 1934. 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 the Securities under the DTC system must be made by or through Direct Participants, which will receive a credit for the Securities on DTC's records. The ownership interest of each actual purchaser of each Security ("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 Securities 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 Securities, except in the event that use of the book-entry system for the Securities is discontinued.

To facilitate subsequent transfers, all Securities deposited by Participants with DTC are registered in the name of DTC's partnership nominee, Cede & Co. The deposit of the Securities 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 Securities; DTC's records reflect only the identity of the Direct Participants to whose accounts such Securities 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 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.

14

Neither DTC nor Cede & Co. will consent or vote with respect to the Securities. Under its usual procedures, DTC mails an Omnibus Proxy to the Company as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.'s consenting or voting rights to those Direct Participants to whose accounts the Securities are credited on the record date (identified in a listing attached to the Omnibus Proxy).

Principal, interest and any premium payments on the Securities will be made to DTC. DTC's practice is to credit Direct Participants' accounts on 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 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 applicable 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 applicable 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 Securities at any time by giving reasonable notice to the Company or the applicable Trustee. Under such circumstances, if a successor securities depository is not obtained, certificates for such series of Securities 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 Securities. In that event, certificates for such series of Securities 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 Securities 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.

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

II-3


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 of 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 represented 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.

(c) Each Note shall bear interest from the later of (1) its Original Issue Date (or, if pursuant to Section 2.13 hereof, a Global Note has two or more Original Issue Dates, interest shall, beginning on each such Original Issue Date, begin to accrue for that part of the principal amount of such Global Note to which that Original Issue Date is applicable), or (2) the most recent date to which interest has been paid or duly provided for with respect to such Note until the principal of such Note is paid or made available for payment, and interest on each Note shall be payable on each Interest Payment Date after the Original Issue Date.

(G) that all consents or approvals of Oklahoma Corporation Commission (or any successor agency) and of any other federal or state regulatory agency required in connection with the Company's execution and delivery of this Indenture, such series of Notes and any Senior Note First Mortgage Bonds have been obtained and not withdrawn (except that no statement need be made with respect to state securities laws); and

(1) if the issuance of such Notes pursuant to this Indenture will affect the Trustee's own rights, duties or immunities under the Notes and this Indenture or otherwise in a manner that is not reasonably acceptable to the Trustee;

(2) if the Trustee, being advised by counsel, determines that such action may not lawfully be taken; or

(3) if the Trustee in good faith by its Board of Directors, executive officers or a trust committee of directors and/or responsible officers determines that such action would expose the Trustee to personal liability to Holders of any outstanding Notes.

Any such request shall constitute a representation and warranty by the Company that the statements made in the Officers' Certificate delivered to the Trustee prior to the authentication and issuance of the first Note of such series are true and correct on the date thereof as if made on and as of the date thereof.

SECTION 2.06. EXCHANGE AND REGISTRATION OF TRANSFER OF NOTES.

(a) Subject to Section 2.13 hereof, Notes may be exchanged for one or more new Notes of any authorized denominations and of a like aggregate principal amount, series and stated maturity and having the same terms and Original Issue Date or Dates. Notes to be exchanged shall be surrendered at any of the offices or agencies to be maintained pursuant to Section 6.02 hereof, and the Trustee shall deliver in exchange therefor the Note or Notes which the Noteholder making the exchange shall be entitled to receive.

(b) The Trustee shall keep, at one of said offices or agencies, a register or registers in which, subject to such reasonable regulations as it may prescribe, the Trustee shall register or cause to be registered Notes and shall register or cause to be registered the transfer of Notes as in this Article Two provided. Such register shall be in written form or in any other form capable of being converted into

10

written form within a reasonable time. At all reasonable times, such register shall be open for inspection by the Company. Upon due presentment for registration of transfer of any Note at any such office or agency, the Company shall execute and the Trustee shall register, authenticate and deliver in the name of the transferee or transferees one or more new Notes of any authorized denominations and of a like aggregate principal amount, series and stated maturity and having the same terms and Original Issue Date or Dates.

(c) All Notes presented for registration of transfer or for exchange, redemption or payment shall be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and the Trustee and duly executed by the Holder or the attorney in fact of such Holder duly authorized in writing.

(e) The Trustee shall not be required to exchange or register a transfer of any Notes selected, called or being called for redemption (including Notes, if any, redeemable at the option of the Holder provided such Notes are then redeemable at such Holder's option) except, in the case of any Note to be redeemed in part, the portion thereof not to be so redeemed.

(f) If the principal amount, and applicable premium, of part, but not all of a Global Note is paid, then upon surrender to the Trustee of such Global Note, the Company shall execute, and the Trustee shall authenticate, deliver and register, a Global Note in an authorized denomination in aggregate principal amount equal to, and having the same terms, Original Issue Date or Dates and series as, the unpaid portion of such Global Note.

SECTION 2.07. MUTILATED, DESTROYED, LOST OR STOLEN NOTES.

(a) If any temporary or definitive Note shall become mutilated or be destroyed, lost or stolen, the Company shall execute, and upon its request the Trustee shall authenticate and deliver, a new Note of like form and principal amount and having the same terms and Original Issue Date or Dates and bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, the Trustee and any paying agent or Authenticating Agent such security or indemnity as may be required by them to save each of them harmless, and, in every case of destruction, loss or theft of a Note, the applicant shall also furnish to the Company and to the Trustee evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

(b) The Trustee shall authenticate any such substituted Note and deliver the same upon the written request or authorization of any officer of the Company. Upon the issuance of any substituted Note, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. If any Note which has matured, is about to mature, has been redeemed or called for redemption shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substituted Note, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Note) if the applicant for such payment shall furnish to the Company, the Trustee and any paying agent or Authenticating Agent such security or indemnity as may be required by them to save each of them harmless and, in case of destruction, loss or theft, evidence satisfactory to the Company and the Trustee of the destruction, loss or theft of such Note and of the ownership thereof.

(c) Every substituted Note issued pursuant to this Section 2.07 by virtue of the fact that any Note is mutilated, destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not such destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder. All Notes shall be held and owned upon the express condition that, to the

11

extent permitted by law, the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender.

SECTION 2.08. TEMPORARY NOTES. Pending the preparation of definitive Notes, the Company may execute and the Trustee shall authenticate and deliver temporary Notes (printed, lithographed or otherwise reproduced). Temporary Notes shall be issuable in any authorized denomination and substantially in the form of the definitive Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the definitive Notes. Without unreasonable delay the Company shall execute and shall deliver to the Trustee definitive Notes and thereupon any or all temporary Notes shall be surrendered in exchange therefor at the corporate trust office of the Trustee, and the Trustee shall authenticate, deliver and register in exchange for such temporary Notes an equal aggregate principal amount of definitive Notes. Such exchange shall be made by the Company at its own expense and without any charge therefor to the Noteholders. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits under this Indenture as definitive Notes authenticated and delivered hereunder.

SECTION 2.09. CANCELLATION OF NOTES PAID, ETC. All Notes surrendered for the purpose of payment, redemption, exchange or registration of transfer shall be surrendered to the Trustee for cancellation and promptly cancelled by it and no Notes shall be issued in lieu thereof except as expressly permitted by this Indenture. The Company's acquisition of any Notes shall operate as a redemption or satisfaction of the indebtedness represented by such Notes and such Notes shall be surrendered by the Company to and cancelled by the Trustee.

SECTION 2.10. INTEREST RIGHTS PRESERVED. Each Note delivered under this Indenture upon transfer of or in exchange for or in lieu of any other Note shall carry all the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note, and each such Note shall be so dated that neither gain nor loss of interest shall result from such transfer, exchange or substitution.

SECTION 2.11. SPECIAL RECORD DATE. If and to the extent that the Company fails to make timely payment or provision for timely payment of interest on any series of Notes (other than on an Interest Payment Date that is a maturity date), that interest shall cease to be payable to the Persons who were the Noteholders of such series at the applicable Regular Record Date. In that event, when moneys become available for payment of the interest, the Trustee shall (a) establish a date of payment of such interest and a Special Record Date for the payment of that interest, which Special Record Date shall be not more than 15 nor fewer than 10 days prior to the date of the proposed payment and (b) mail notice of the date of payment and of the Special Record Date not fewer than 10 days preceding the Special Record Date to each Noteholder of such series at the close of business on the 15th day preceding the mailing at the address of such Noteholder, as it appeared on the register for the Notes. On the day so established by the Trustee the interest shall be payable to the Holders of the applicable Notes at the close of business on the Special Record Date.

SECTION 2.12. PAYMENT OF NOTES. Payment of the principal, interest and premium on all Notes shall be payable as follows:

(a) On or before 9:30 a.m., New York City time, of the day on which payment of principal, interest and premium is due on any Global Note pursuant to the terms thereof, the Company shall deliver to the Trustee funds available on such date sufficient to make such payment, by wire transfer of immediately available funds or by instructing the Trustee to withdraw sufficient funds from an account maintained by the Company with the Trustee or such other method as is acceptable to the Trustee and the Depositary. On or before 10:00 a.m., New York City time, or such other time as shall be agreed upon between the Trustee and the Depositary, of the day on which any payment of interest

12

is due on any Global Note (other than at maturity), the Trustee shall pay to the Depositary such interest in same day funds. On or before 10:00 a.m., New York City time or such other time as shall be agreed upon between the Trustee and the Depositary, of the day on which principal, interest payable at maturity and premium, if any, is due on any Global Note, the Trustee shall deposit with the Depositary the amount equal to the principal, interest payable at maturity and premium, if any, by wire transfer into the account specified by the Depositary. As a condition to the payment, at maturity or upon redemption, of any part of the principal and applicable premium of any Global Note, the Depositary shall surrender, or cause to be surrendered, such Global Note to the Trustee, whereupon a new Global Note shall be issued to the Depositary pursuant to
Section 2.06(f) hereof.

(b) With respect to any Note that is not a Global Note, principal, applicable premium and interest due at the maturity of the Note shall be payable in immediately available funds when due upon presentation and surrender of such Note at the corporate trust office of the Trustee or at the authorized office of any paying agent. Interest on any Note that is not a Global Note (other than interest payable at maturity) shall be paid to the Holder thereof as its name appears on the register by check payable in clearinghouse funds; provided that if the Trustee receives a written request from any Holder of Notes, the aggregate principal amount of which having the same Interest Payment Date equals or exceeds $10,000,000, on or before the applicable Regular Record Date for such Interest Payment Date, interest shall be paid by wire transfer of immediately available funds to a bank within the continental United States designated by such Holder in its request or by direct deposit into the account of such Holder designated by such Holder in its request if such account is maintained with the Trustee or any paying agent.

(c) Subject to Article Eight hereof, all payments made by the Company to the Trustee on a series of Senior Note First Mortgage Bonds shall be applied by the Trustee to pay, when due, principal of, premium, if any, and interest on the related series of Notes and, to the extent so applied, shall satisfy the Company's obligations on such Notes. The Company shall pay to the Trustee principal of, premium, if any, and interest on a series of Senior Note First Mortgage Bonds in a manner and at a time that will enable the Trustee to make payments when due, of the principal of, premium, if any, and interest on the related series of Notes.

SECTION 2.13. NOTES ISSUABLE IN THE FORM OF A GLOBAL NOTE.

(a) If the Company shall establish pursuant to Section 2.05 that the Notes of a particular series are to be issued in whole or in part in the form of one or more Global Notes, then the Company shall execute and the Trustee shall, in accordance with Section 2.05 and the Company Order delivered to the Trustee thereunder, authenticate and deliver such Global Note or Notes, which (i) shall represent, shall be denominated in an amount equal to the aggregate principal amount of, and shall have the same terms as, the outstanding Notes of such series to be represented by such Global Note or Notes, (ii) shall be registered in the name of the Depositary or its nominee, (iii) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary's instruction and (iv) shall bear a legend substantially to the following effect: "This Note is a Global Note registered in the name of the Depositary (referred to herein) or a nominee thereof and, unless and until it is exchanged in whole or in part for the individual notes represented hereby, this Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. Unless this Global Note is presented by an authorized representative of The Depository Trust Company (55 Water Street, New York, New York), to the trustee for registration of transfer, exchange or payment, and any certificate issued is registered in the name of Cede & Co. or such other name as requested by an authorized representative of The Depository Trust Company and any payment is made to Cede & Co., any transfer, pledge or other use hereof for value or otherwise by or to any person is wrongful since the registered owner hereof, Cede & Co., has an interest herein" or such other legend as may be required by the rules and regulations of the Depositary.

13

(b) Notwithstanding any other provision of Section 2.06 or of this Section 2.13, unless the terms of a Global Note expressly permit such Global Note to be exchanged in whole or in part for individual Notes, a Global Note may be transferred, in whole but not in part, only as described in the legend thereto.

(c) (i) If at any time the Depositary for a Global Note notifies the Company that it is unwilling or unable to continue as Depositary for such Global Note or if at any time the Depositary for the 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 such Global Note. If a successor Depositary for such 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 pursuant to Section 2.05(c)(vi) hereof shall no longer be effective with respect to the series of Notes evidenced by such Global Note and the Company shall execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of individual Notes of such series in exchange for such Global Note, shall authenticate and deliver, individual Notes of such series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of the Global Note in exchange for such Global Note. The Trustee shall not be charged with knowledge or notice of the ineligibility of a Depositary unless a responsible officer assigned to and working in its corporate trustee administration department shall have actual knowledge thereof.

(ii) The Company may at any time and in its sole discretion determine that all outstanding (but not less than all) Notes of a series 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 in exchange for such Global Note, shall authenticate and deliver individual Notes 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.

(iii) In any exchange provided for in any of the preceding two paragraphs, the Company will execute and the Trustee will authenticate and deliver individual Notes in definitive registered form in authorized denominations. Upon the exchange of a Global Note for individual Notes, such Global Note shall be cancelled by the Trustee. Notes issued in exchange for a Global Note pursuant to this Section shall be registered in such names and in such authorized denominations as the Depositary for such Global Note, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Notes to the Depositary for delivery to the persons in whose names such Notes are so registered, or if the Depositary shall refuse or be unable to deliver such Notes, the Trustee shall deliver such Notes to the persons in whose names such Notes are registered, unless otherwise agreed upon between the Trustee and the Company, in which event the Company shall cause the Notes to be delivered to the persons in whose names such Notes are registered.

(d) Neither the Company, the Trustee, any Authenticating Agent nor any paying agent shall have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests of a Global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interest.

(e) Pursuant to the provisions of this subsection, at the option of the Trustee and upon 30 days' written notice to the Depositary but not prior to the first Interest Payment Date of the respective Global Notes, the Depositary shall be required to surrender any two or more Global Notes which have identical terms, including, without limitation, identical maturities, interest rates and redemption provisions (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 each applicable Original

14

Issue Date and the principal amount applicable to each such Original Issue Date. The exchange contemplated in this subsection shall be consummated at least 30 days prior to any Interest Payment Date applicable to any of the Global Notes surrendered to the Trustee. Upon any exchange of any Global Note with two or more Original Issue Dates, whether pursuant to this Section or pursuant to
Section 2.06 or Section 3.03 hereof, the aggregate principal amount of the Notes with a particular Original Issue Date shall be the same before and after such exchange, after giving effect to any retirement of Notes and the Original Issue Dates applicable to such Notes occurring in connection with such exchange.

ARTICLE THREE

SECTION 3.01. APPLICABILITY OF ARTICLE. Such of the Notes as are, by their terms, redeemable prior to their stated maturity date at the option of the Company, may be redeemed by the Company at such times, in such amounts and at such prices as may be specified therein and in accordance with the provisions of this Article Three.

SECTION 3.02. NOTICE OF REDEMPTION; SELECTION OF NOTES.

(a) The election of the Company to redeem any Notes shall be evidenced by a Board Resolution which shall be given with notice of redemption to the Trustee at least 45 days (or such shorter period acceptable to the Trustee in its sole discretion) prior to the redemption date specified in such notice.

(b) Notice of redemption to each Holder of Notes to be redeemed as a whole or in part shall be given by the Trustee, in the manner provided in Section 15.10, no less than 30 nor more than 60 days prior to the date fixed for redemption. Any notice which is given in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Noteholder receives the notice. In any case, failure duly to give such notice, or any defect in such notice, to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note.

(c) Each such notice shall specify the date fixed for redemption, the places of redemption and the redemption price at which such Notes are to be redeemed, and shall state that payment of the redemption price of such Notes or portion thereof to be redeemed will be made upon surrender of such Notes at such places of redemption, that interest accrued to the date fixed for redemption will be paid as specified in such notice, and that from and after such date interest thereon shall cease to accrue. If less than all of a series of Notes having the same terms are to be redeemed, the notice shall specify the Notes or portions thereof to be redeemed. If any Note is to be redeemed in part only, the notice which relates to such Note shall state the portion of the principal amount thereof to be redeemed, and shall state that, upon surrender of such Note, a new Note or Notes having the same terms in aggregate principal amount equal to the unredeemed portion thereof will be issued.

(d) Unless otherwise provided by a supplemental indenture or Company Order under Section 2.05 hereof, if less than all of a series of Notes is to be redeemed, the Trustee shall select in such manner as it shall deem appropriate and fair in its discretion the particular Notes to be redeemed in whole or in part and shall thereafter promptly notify the Company in writing of the Notes so to be redeemed. If less than all of a series of Notes represented by a Global Note is to be redeemed, the particular Notes or portions thereof of such series to be redeemed shall be selected by the Depositary for such series of Notes in such manner as the Depositary shall determine. Notes shall be redeemed only in denominations of $1,000, provided that any remaining principal amount of a Note redeemed in part shall be a denomination authorized under this Indenture.

(e) If at the time of the mailing of any notice of redemption the Company shall not have irrevocably directed the Trustee to apply funds deposited with the Trustee or held by it and available to be used for the redemption of Notes to redeem all the Notes called for redemption, such notice, at

15

ARTICLE EIGHT.
REMEDIES OF THE TRUSTEE AND
NOTEHOLDERS ON EVENTS OF DEFAULT

SECTION 8.01. EVENTS OF DEFAULT.

(a) If one or more of the following Events of Default shall have occurred and be continuing:

(1) default in the payment of any installment of interest upon any of the Notes as and when the same shall become due and payable, and continuance of such default for a period of 60 days;

(2) default in the payment of the principal of or any premium on any of the Notes as and when the same shall become due and payable and continuance of such default for five days;

25

(3) failure on the part of the Company duly to observe or perform any other of the covenants or agreements on the part of the Company contained in the Notes or in this Indenture for a period of 90 days after the date on which written notice of such failure, requiring the same to be remedied and stating that such notice is a "Notice of Default" hereunder, shall have been given to the Company by the Trustee by registered mail, or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Notes at the time outstanding;

(4) prior to the Release Date, a completed default (as defined in the First Mortgage) has occurred and is continuing, and the Mortgage Trustee, the Company or Holders of at least 25% in aggregate principal amount of the Notes at the time outstanding shall have given written notice thereof to the Trustee;

(5) the entry of a decree or order by a court having jurisdiction over the Company for relief in respect of the Company under Title 11 of the United States Code, as now constituted or hereafter amended, or any other applicable federal or state bankruptcy, insolvency or other similar law, or appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator or similar official of the Company or of any substantial part of its property, or ordering the winding-up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days; or

(6) the filing by the Company of a petition or answer or consent seeking relief under Title 11 of the United States Code, as now constituted or hereafter amended, or any other applicable federal or state bankruptcy, insolvency or other similar law, or the consent by it to the institution of proceedings thereunder or to the filing of any such petition or to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator or other similar official of the Company or of any substantial part of its property, or the failure of the Company generally to pay its debts as such debts become due, or the taking of corporate action by the Company to effectuate any such action;

then and in each and every such case, unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the Holders of a majority in aggregate principal amount of the Notes then outstanding, by notice in writing to the Company (and to the Trustee if given by Noteholders), may declare the principal of all the Notes to be due and payable immediately and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Notes contained to the contrary notwithstanding and, upon the Notes being declared to be due and payable, the Trustee can immediately file with the Mortgage Trustee a written demand for redemption of all Senior Note First Mortgage Bonds pursuant to the applicable provisions of the supplemental indentures to the First Mortgage. This provision, however, is subject to the condition that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided and prior to the mailing to the Trustee by the Mortgage Trustee of a firm, valid and unconditional notice to the Trustee of the acceleration of all of the first mortgage bonds issued and outstanding under the First Mortgage, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all matured installments of interest upon all of the Notes and the principal of and any premium on any and all Notes which shall have become due otherwise than by acceleration (with interest on overdue installments of interest, to the extent that payment of such interest is enforceable under applicable law, and on such principal and applicable premium at the rate borne by the Notes to the date of such payment or deposit) and all sums paid or advanced by the Trustee hereunder, the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 9.06 hereof, and any and all defaults under this Indenture, other than the non-payment of principal of and accrued interest on Notes which shall have become due solely by acceleration of maturity, shall have been cured or waived (including any defaults under the First Mortgage, as evidenced by notice thereof from the Mortgage Trustee to the Trustee) -- then and in every such case such payment or

26

deposit shall cause an automatic waiver of the Event of Default and its consequences and shall cause an automatic rescission and annulment of the acceleration of the Notes; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default, or shall impair any right consequent thereon.

(b) If the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of such rescission or annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company and the Trustee shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company and the Trustee shall continue as though no such proceeding had been taken.

SECTION 8.02. PAYMENT OF NOTES ON DEFAULT; SUIT THEREFOR.

(a) The Company covenants that in case of:

(1) default in the payment of any installment of interest upon any of the Notes as and when the same shall become due and payable, and continuance of such default for a period of 30 days; or

(2) default in the payment of the principal of or any premium on any of the Notes as and when the same shall have become due and payable whether at the stated maturity thereof, upon redemption thereof (provided that such redemption is not conditioned upon the deposit of sufficient moneys for such redemption), upon declaration of acceleration or otherwise.

then, upon demand of the Trustee, the Company shall pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount that then shall have so become due and payable on all such Notes for principal and any premium or interest, or both, as the case may be, with interest upon the overdue principal and any premium and (to the extent that payment of such interest is enforceable under applicable law) upon the overdue installments of interest at the rate borne by the Notes; and, in addition thereto, such further amounts as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and counsel, any expenses or liabilities incurred by the Trustee hereunder other than through its negligence or bad faith, and any other amounts due the Trustee under Section 9.06 hereof.

(b) If the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, including, prior to the Release Date, to exercise any rights to that end it may have as a holder of Senior Note First Mortgage Bonds, and may enforce any such judgment or final decree against the Company or any other obligor on the Notes and collect in the manner provided by law out of the property of the Company or any other obligor on such series of Notes wherever situated, the moneys adjudged or decreed to be payable.

(c) If there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under the United States Bankruptcy Code or any other applicable law, or in case a receiver or trustee shall have been appointed for the property of the Company or such other obligor, or in the case of any similar judicial proceedings relative to the Company or other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to this Section 8.02, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and any premium and interest owing and unpaid in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including, prior to the Release Date, any claims of the Trustee as holder of Senior Note First Mortgage Bonds and including any amounts due to the Trustee under Section 9.06 hereof) and of the Holders of Notes allowed in such judicial proceedings

27

relative to the Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute the same after the deduction of its charges and expenses.

(d) All claims and rights of action under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof in any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall be for the ratable benefit of the Holders of the Notes in respect of which such action was taken.

(e) Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent or to accept or adopt on behalf of any Noteholder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Noteholder in any such proceeding.

SECTION 8.03. APPLICATION OF MONEYS COLLECTED BY TRUSTEE. Any moneys collected by the Trustee with respect to any of the Notes pursuant to this Article shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such moneys, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof if fully paid.

FIRST: To the payment of all amounts due to the Trustee pursuant to Section 9.06;

SECOND: If the principal of the outstanding Notes in respect of which such moneys have been collected shall not have become due and be unpaid, to the payment of interest on the Notes, in the order of the maturity of the installments of such interest, with interest (to the extent allowed by law and to the extent that such interest has been collected by the Trustee) upon the overdue installments of interest at the rate borne by the Notes, such payments to be made ratably to the persons entitled thereto, and then to the payment to the Holders entitled thereto of the unpaid principal of and applicable premium on any of the Notes which shall have become due (other than Notes previously called for redemption for the payment of which moneys are held pursuant to the provisions of this Indenture), whether at stated maturity or by redemption, in the order of their due dates, beginning with the earliest due date, and if the amount available is not sufficient to pay in full all Notes due on any particular date, then to the payment thereof ratably, according to the amounts of principal and applicable premium due on that date, to the Holders entitled thereto, without any discrimination or privilege.

THIRD: If the principal of the outstanding Notes in respect of which such moneys have been collected shall have become due, by declaration or otherwise, to the payment of the whole amount then owing and unpaid upon the Notes for principal and any premium and interest thereon, with interest on the overdue principal and any premium and (to the extent allowed by law and to the extent that such interest has been collected by the Trustee) upon overdue installments of interest at the rate borne by the Notes; and in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Notes, then to the payment of such principal and any premium and interest without preference or priority of principal and any premium over interest, or of interest over principal and any premium or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal and any premium and accrued and unpaid interest; and

FOURTH: to the payment of the remainder, if any, to the Company or its successors or assigns, or to whomsoever may lawfully be entitled to the same, or as a court of competent jurisdiction may determine.

SECTION 8.04. PROCEEDINGS BY NOTEHOLDERS.

(a) No Holder of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect

28

to this Indenture or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless such Holder previously shall have given to the Trustee written notice of an Event of Default with respect to such Note and of the continuance thereof, as hereinabove provided, and unless also Noteholders of a majority in aggregate principal amount of the Notes then outstanding affected by such Event of Default shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding.

(b) Notwithstanding any other provision in this Indenture, however, the rights of any Holder of any Note to receive payment of the principal of and any premium and interest on such Note, on or after the respective due dates expressed in such Note or on the applicable redemption date, or to institute suit for the enforcement of any such payment on or after such respective dates shall not be impaired or affected without the consent of such Holder.

SECTION 8.05. PROCEEDINGS BY TRUSTEE. In case of an Event of Default hereunder the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture, including, prior to the Release Date, its rights as holder of the Senior Note First Mortgage Bonds, by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted to it under this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

SECTION 8.06. REMEDIES CUMULATIVE AND CONTINUING. All powers and remedies given by this Article Eight to the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any powers and remedies hereof or of any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes in exercising any right or power accruing upon any default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or an acquiescence therein; and, subject to Section 8.04, every power and remedy given by this Article Eight or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders.

SECTION 8.07. DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY MAJORITY OF NOTEHOLDERS. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding shall have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee; provided, that (subject to Section 9.01) the Trustee shall have the right to decline to follow any such direction if the Trustee being advised by counsel determines that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith by its board of directors or trustees, executive committee, or a trust committee of directors or trustees or responsible officers shall determine that the action or proceeding so directed would involve the Trustee in personal liability or would be unduly prejudicial to the rights of Noteholders not joining in such directions. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of all of the Holders of the Notes waive any past default or Event of Default hereunder and its consequences except a default in the payment of principal of or any premium or interest on the Notes. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder, respectively, but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. Whenever any default or Event of Default

29

hereunder shall have been waived as permitted by this Section 8.07, said default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing.

SECTION 8.08. NOTICE OF DEFAULT. The Trustee shall, within 90 days after the occurrence of a default, give to all Holders of the Notes, in the manner provided in section 15.10, notice of such default, unless such default shall have been cured before the giving of such notice, the term "default" for the purpose of this Section 8.08 being hereby defined to be any event which is or after notice or lapse of time or both would become an Event of Default; provided that, except in the case of default in the payment of the principal of or any premium or interest on any of the Notes, or in the payment of any sinking or purchase fund installments, the Trustee shall be protected in withholding such notice if and so long as its board of directors or trustees, executive committee, or a trust committee of directors or trustees or responsible officers in good faith determines that the withholding of such notice is in the interests of the Holders of the Notes. The Trustee shall not be charged with knowledge of any Event of Default unless a responsible officer of the Trustee assigned to the corporate trustee department of the Trustee shall have actual knowledge of such Event of Default.

SECTION 8.09. UNDERTAKING TO PAY COSTS. All parties to this Indenture agree, and each Holder of any Note by acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but this Section 8.09 shall not apply to any suit instituted by the Trustee, or to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than 10% in principal amount of the Notes outstanding, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or any premium or interest on any Note on or after the due date expressed in such Note or the applicable redemption date.

(a) The Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. If an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

(b) No provisions of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

(1) prior to the occurrence of any Event of Default and after the curing or waiving of all Events of Default which may have occurred

(A) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(B) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein,

30

upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture;

(2) the Trustee shall not be liable for any error of judgment made in good faith by a responsible officer or officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and

(3) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with Section 8.07 hereof relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee under this Indenture.

(d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Noteholders, pursuant to this Indenture, unless such Noteholders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be incurred by such exercise;

(e) the Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture;

(f) prior to the occurrence of an Event of Default hereunder and after the curing or waiving of all Events of Default, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, note or other paper or document, unless requested in writing to do so by the Holders of at least a majority in principal amount of the then outstanding Notes; provided that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by this Indenture, the Trustee may require reasonable indemnity against such expense or liability as a condition to so proceeding;

(g) no provision of this Indenture shall require the Trustee to extend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it; and

31

(h) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or through agents or attorneys; provided that the Trustee shall not be liable for the conduct or acts of any such agent or attorney that shall have been appointed in accordance herewith with due care.

SECTION 9.03. NO RESPONSIBILITY FOR RECITALS, ETC. The recitals contained herein and in the Notes (except in the certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by the Trustee in conformity with this Indenture. The Trustee shall not be responsible for recording or filing this Indenture, any supplemental indenture, or any financing or continuation statement in any public office at any time or times.

SECTION 9.04. TRUSTEE, AUTHENTICATING AGENT, PAYING AGENT OR REGISTRAR MAY OWN NOTES.

SECTION 9.05. MONEYS TO BE HELD IN TRUST. Subject to Section 5.04, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by law. The Trustee may allow and credit to the Company interest on any money received hereunder at such rate, if any, as may be agreed upon by the Company and the Trustee from time to time as may be permitted by law.

SECTION 9.06. COMPENSATION AND EXPENSES OF TRUSTEE. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation (which shall not be limited by any law in regard to the compensation of a trustee of an express trust), and the Company shall pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with this Indenture (including the reasonable compensation and the reasonable expenses and disbursements of its counsel and agents, including any Authenticating Agents, and of all persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence or bad faith. The Company also covenants to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on the part of the Trustee and arising out of or in connection with the acceptance or administration of this trust, including the costs and expenses of defending itself against any claim or liability. The obligations of the Company under this Section 9.06 to compensate the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall constitute additional indebtedness hereunder. Such additional indebtedness shall be secured by a lien prior to that of the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of any particular Notes.

SECTION 9.07. OFFICERS' CERTIFICATE AS EVIDENCE. Whenever in the administration of this Indenture, the Trustee shall deem it necessary or desirable that a matter be proved or established prior to the taking, suffering or omitting of any action hereunder, such matter (unless other evidence in respect thereof is herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers' Certificate delivered to the Trustee, and such Officers' Certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under this Indenture in reliance thereon.

SECTION 9.08. CONFLICTING INTEREST OF TRUSTEE. The Trustee shall be subject to and shall comply with the provisions of Section 310 of the TIA; provided that, to the extent permitted by law, Boatmen's First National Bank of Oklahoma shall not be deemed to have a conflicting interest for

32

purposes of Section 310(b) of the TIA because of its capacity as trustee under the First Mortgage. Nothing in this Indenture shall be deemed to prohibit the Trustee or the Company from making any application permitted pursuant to such section.

SECTION 9.09. EXISTENCE AND ELIGIBILITY OF TRUSTEE. There shall at all times be a Trustee hereunder which Trustee shall at all times be a corporation organized and doing business under the laws of the United States or any State thereof or of the District of Columbia (or a corporation or other Person permitted to act as trustee by the Commission), subject to supervision or examination by such bodies and authorized under such laws to exercise corporate trust powers and having a combined capital and surplus of at least $150,000,000. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid authority, then for the purposes of this Section 9.09, the combined capital and surplus shall be deemed to be as set forth in its most recent report of condition so published. No obligor upon the Notes or Person directly or indirectly controlling, controlled by, or under common control with such obligor shall serve as Trustee. If at any time the Trustee shall cease to be eligible in accordance with this Section 9.09, the Trustee shall resign immediately in the manner and with the effect specified in
Section 9.10 hereof.

SECTION 9.10. RESIGNATION OR REMOVAL OF TRUSTEE.

(d) If at any time (1) the Trustee shall cease to be eligible in accordance with Section 9.09 hereof and shall fail to resign after written request therefor by the Company or by any Holder who has been a bona fide Holder for at least six months, (2) the Trustee shall fail to comply with Section 9.08 hereof after written request therefor by the Company or any such Holder, or (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then the Trustee may be removed forthwith by an instrument or concurrent instruments in writing filed with the Trustee and either:

(1) signed by the President or any Vice President of the Company and attested by the Secretary or an Assistant Secretary of the Company; or

(2) signed and acknowledged by the Holders of a majority in principal amount of outstanding Notes or by their attorneys in fact duly authorized.
