Ladies and Gentlemen:

     ONEOK, Inc., an Oklahoma corporation (the "Company"), proposes to issue and
sell an aggregate of 12,000,000 shares (the "Firm Shares") of the Company's
common stock, $0.01 par value per share, together with each associated preferred
stock purchase right under the Rights Agreement, dated as of November 26, 1997
(the "Rights Agreement"), between the Company and Bank One, N.A., formerly known
as Liberty Bank and Trust Company of Oklahoma, N.A., as Rights Agent (the
"Common Stock"), to you and to the other underwriters named in Schedule I hereto
(collectively, the "Underwriters"), for whom you are acting as representatives
(collectively, the "Representatives"). The Company has also agreed to grant to
the Underwriters an option (the "Option") to purchase up to an additional
1,800,000 shares (the "Option Shares") of Common Stock on the terms and for the
purposes set forth in Section 1(b). The Firm Shares and the Option Shares are
hereinafter collectively referred to as the "Shares." The term "Representatives"
as used herein shall be deemed to mean the firms or companies addressed hereby.
If there are any Underwriters in addition to the Representatives, you represent
that you have been authorized by each of the Underwriters to enter into this
Underwriting Agreement (this "Agreement") on their behalf and to act for them in
the manner herein provided in all matters




relating to carrying out the provisions of this Agreement. All obligations of
the Underwriters hereunder are several and not joint.

     The initial public offering price per share for the Shares and the purchase
price per share for the Shares to be paid by the several Underwriters shall be
agreed upon by the Company and the Representatives, acting on behalf of the
several Underwriters, and such agreement shall be set forth in a separate
written instrument substantially in the form of Exhibit A hereto (the "Price
Determination Agreement"). The Price Determination Agreement may take the form
of an exchange of any standard form of written telecommunication between the
Company and the Representatives and shall specify such applicable information as
is indicated in Exhibit A hereto. The offering of the Shares will be governed by
this Agreement, as supplemented by the Price Determination Agreement. From and
after the date of the execution and delivery of the Price Determination
Agreement, this Agreement shall be deemed to incorporate, and, unless the
context otherwise indicates, all references contained herein to "this Agreement"
and to the phrase "herein" shall be deemed to include the Price Determination
Agreement.

     The Company confirms as follows its agreements with the Representatives and
the several other Underwriters.

1.          Agreement to Sell and Purchase.

     (a)           On the basis of the representations, warranties and
            agreements of the Company herein contained and subject to all the
            terms and conditions of this Agreement, the Company agrees to sell
            to each Underwriter, and each Underwriter, severally and not
            jointly, agrees to purchase from the Company at the purchase price
            per share for the Firm Shares to be agreed upon by the Underwriters
            and the Company in accordance with Section 1(c) or 1(d) hereof and
            set forth in the Price Determination Agreement, the number of Firm
            Shares set forth opposite the name of such Underwriter in Schedule
            I, plus such additional number of Firm Shares which such Underwriter
            may become obligated to purchase pursuant to Section 10 hereof. If
            the Company elects to rely on Rule 430A of the Rules and Regulations
            (as hereinafter defined), Schedule I may be attached to the Price
            Determination Agreement.

     (b)           Subject to all the terms and conditions of this Agreement,
            the Company grants the Option to the Underwriters to purchase,
            severally and not jointly, up to 1,800,000 Option Shares from the
            Company at the same price per share as the Underwriters will pay for
            the Firm Shares. The Option may be exercised only to cover
            over-allotments in the sale of the Firm Shares by the Underwriters
            and may be exercised in whole or in part at any time (but not more
            than once) on or before the 30th day after the date of this
            Agreement (or, if the Company has elected to rely on Rule 430A, on
            or before the 30th day after the date of the Price Determination
            Agreement), upon written or telegraphic notice (the "Option Shares
            Notice") by the Representatives to the Company no later than 12:00
            noon, New York City time, at least two and no more than five
            business days before the date specified for closing in the Option
            Shares Notice (the "Option Closing Date")

                                        2



            setting forth the aggregate number of Option Shares to be purchased
            and the time and date for such purchase. On the Option Closing Date,
            the Company will issue and sell to the Underwriters the number of
            Option Shares set forth in the Option Shares Notice and each
            Underwriter will purchase such percentage of the Option Shares as is
            equal to the percentage of Firm Shares that such Underwriter is
            purchasing, as adjusted as the Representatives deem advisable to
            avoid fractional shares.

     (c)           If the Company has elected not to rely on Rule 430A of the
            Rules and Regulations, the initial public offering price per share
            for the Firm Shares and the purchase price per share for the Firm
            Shares to be paid by the several Underwriters shall be agreed upon
            and set forth in the Price Determination Agreement, which shall be
            dated as of the date hereof, and an amendment to the Registration
            Statement (as hereinafter defined) containing such per share price
            information shall be filed before the Registration Statement becomes
            effective.

     (d)           If the Company has elected to rely on Rule 430A of the Rules
            and Regulations, the initial public offering price per share for the
            Firm Shares and the purchase price per share for the Firm Shares to
            be paid by the several Underwriters shall be agreed upon and set
            forth in the Price Determination Agreement.

2.          Delivery and Payment.

     (a)           Delivery of the Firm Shares shall be made to the
            Representatives for the accounts of the Underwriters against payment
            of the purchase price by wire transfer in immediately available
            funds to an account designated in writing by the Company to the
            Representatives. Such payment shall be made at 10:00 a.m., New York
            City time, on the third business day after the date on which the
            first bona fide offering of the Firm Shares to the public is made by
            the Underwriters or at such time on such other date, not later than
            ten business days after such first offering date, as may be agreed
            upon by the Company and the Representatives (such date is
            hereinafter referred to as the "Closing Date"). Delivery of the Firm
            Shares shall be made through the facilities of The Depository Trust
            Company unless the Representatives shall otherwise instruct.

     (b)           To the extent the Option is exercised, delivery of the Option
            Shares against payment by the Underwriters (in the manner specified
            above) will take place in the manner specified above for the Closing
            Date on the Option Closing Date.

     (c)           Certificates evidencing the Shares shall be in definitive
            form and shall be registered in such names and in such denominations
            as the Representatives shall request at least two business days
            prior to the Closing Date or the Option Closing Date, as the case
            may be, by written notice to the Company. For the purpose of
            expediting the checking and packaging of certificates for the
            Shares, the Company

                                        3



            agrees to make such certificates available for inspection at least
            24 hours prior to the Closing Date or the Option Closing Date, as
            the case may be.

     (d)           The cost of original issue tax stamps, if any, in connection
            with the issuance and delivery of the Firm Shares and Option Shares
            by the Company to the Underwriters shall be borne by the Company.
            The Company will pay and save each Underwriter and any subsequent
            holder of the Shares harmless from any and all liabilities with
            respect to or resulting from any failure or delay in paying federal
            and state stamp and other transfer taxes, if any, which may be
            payable or determined to be payable in connection with the original
            issuance or sale to such Underwriter of the Firm Shares and Option
            Shares.

     (e)           Not later than 12:00 p.m. on the second business day
            following the date the Firm Shares are first released by the
            Underwriters for sale to the public, the Company shall deliver or
            cause to be delivered, copies of the Prospectus (as hereinafter
            defined) in such quantities and at such places as the
            Representatives shall request.

3.          Representations and Warranties of the Company.  The Company
     represents, warrants and covenants to each Underwriter that:

     (a)           The Company meets the requirements for use of Form S-3 and a
            registration statement (Registration No. 333-102105) on Form S-3, as
            amended, relating to the Shares, including a preliminary prospectus
            and such amendments to such registration statement as may have been
            required to the date of this Agreement, has been prepared by the
            Company under the provisions of the Securities Act of 1933 (the
            "Act"), and the rules and regulations (collectively referred to as
            the "Rules and Regulations") of the Securities and Exchange
            Commission (the "Commission") thereunder, and has been filed with
            the Commission. The term "preliminary prospectus" as used herein
            means a preliminary prospectus as contemplated by Rule 430 or Rule
            430A ("Rule 430A") of the Rules and Regulations included at any time
            as part of the registration statement. Copies of such registration
            statement and amendments and of each related preliminary prospectus
            have been delivered to each Underwriter. The term "Registration
            Statement" means the registration statement described above, as
            amended at the time it became effective (the "Effective Date"),
            including financial statements and all exhibits and any information
            deemed to be included by Rule 430A or Rule 434 of the Rules and
            Regulations. If the Company files a registration statement to
            register a portion of the Shares and relies on Rule 462(b) of the
            Rules and Regulations for such registration statement to become
            effective upon filing with the Commission (the "Rule 462
            Registration Statement"), then any reference to the "Registration
            Statement" shall be deemed to include the Rule 462 Registration
            Statement, as amended from time to time. The Company will file with
            the Commission a prospectus supplement (the "Prospectus Supplement")
            relating to the Shares pursuant to Rule 424 or Rule 434 under the
            Act. The term "Prospectus" means the form of final prospectus
            included in the

                                        4



            Registration Statement at the Effective Date, as amended and
            supplemented prior to the date of this Agreement and as supplemented
            by the Prospectus Supplement, and shall be deemed to include the
            "electronic Prospectus" provided for use in connection with the
            offering of the Shares as contemplated by Section 4(l) of this
            Agreement. Any reference herein to the Registration Statement, any
            preliminary prospectus or the Prospectus shall be deemed to refer to
            and include (i) the documents incorporated by reference therein
            pursuant to Item 12 of Form S-3 that were filed under the Securities
            Exchange Act of 1934 (the "Exchange Act"), on or before the
            Effective Date or the date of such preliminary prospectus or the
            Prospectus, as the case may be, and (ii) any copy thereof filed with
            the Commission pursuant to its Electronic Data Gathering, Analysis
            and Retrieval System ("EDGAR"). Any reference herein to the terms
            "amend," "amendment" or "supplement" with respect to the
            Registration Statement, any preliminary prospectus or the Prospectus
            shall be deemed to refer to and include the filing of any document
            under the Exchange Act after the Effective Date, or the date of any
            preliminary prospectus or the Prospectus, as the case may be, and
            deemed to be incorporated therein by reference.

     (b)           The Company has not received, and has no notice of, any order
            of the Commission preventing or suspending the use of any
            preliminary prospectus, or instituting proceedings for that purpose.
            Each preliminary prospectus and the Prospectus when filed complied
            in all material respects with the Act and, if filed by electronic
            transmission pursuant to EDGAR (except as may be permitted by
            Regulation S-T under the Act), was identical to the copy thereof
            delivered to the Underwriters for use in connection with the offer
            and sale of the Shares. On the Effective Date, the date the
            Prospectus is first filed with the Commission pursuant to Rule
            424(b) of the Rules and Regulations, at all times subsequent to and
            including the Closing Date and when any post-effective amendment to
            the Registration Statement becomes effective or any amendment or
            supplement to the Prospectus is filed with the Commission, the
            Registration Statement and the Prospectus (as amended or as
            supplemented if the Company shall have filed with the Commission any
            amendment or supplement thereto), including the financial statements
            included or incorporated by reference in the Prospectus, did or will
            comply with all applicable provisions of the Act, the Exchange Act,
            the rules and regulations thereunder (the "Exchange Act Rules and
            Regulations") and the Rules and Regulations and will contain all
            statements required to be stated therein in accordance with the Act,
            the Exchange Act, the Exchange Act Rules and Regulations and the
            Rules and Regulations. On the Effective Date and when any
            post-effective amendment to the Registration Statement becomes
            effective, no part of the Registration Statement or any such
            amendment did or will contain any untrue statement of a material
            fact or omit to state a material fact required to be stated therein
            or necessary in order to make the statements therein not misleading.
            At the Effective Date, the date the Prospectus or any amendment or
            supplement to the Prospectus is filed with the Commission and at the
            Closing Date and, if later, the Option Closing Date, the Prospectus
            did not and will not contain any

                                        5



            untrue statement of a material fact or omit to state a material fact
            necessary to make the statements therein, in the light of the
            circumstances under which they were made, not misleading. The
            foregoing representations and warranties in this Section 3(b) do not
            apply to any statements or omissions made in reliance on and in
            conformity with information relating to any Underwriter furnished in
            writing to the Company by the Representatives specifically for
            inclusion in the Registration Statement or Prospectus or any
            amendment or supplement thereto. For all purposes of this Agreement,
            the amounts of the selling concession and reallowance set forth in
            the Prospectus constitute the only information relating to any
            Underwriter furnished in writing to the Company by the
            Representatives specifically for inclusion in the Registration
            Statement or the Prospectus. The Company has not distributed any
            offering material in connection with the offering or sale of the
            Shares other than the Registration Statement, the preliminary
            prospectus, the Prospectus or any other materials, if any, permitted
            by the Act.

     (c)           The documents that are incorporated by reference in the
            Prospectus or from which information is so incorporated by
            reference, when they became effective or were filed with the
            Commission, as the case may be, complied in all material respects
            with the requirements of the Act or the Exchange Act, as applicable,
            the Exchange Act Rules and Regulations and the Rules and
            Regulations; and any documents so filed and incorporated by
            reference subsequent to the date hereof shall, when they are filed
            with the Commission, conform in all material respects with the
            requirements of the Act and the Exchange Act, as applicable, the
            Exchange Act Rules and Regulations and the Rules and Regulations.

     (d)           The only subsidiaries (as defined in the Rules and
            Regulations) of the Company are the subsidiaries named on Schedule
            II hereto (the "Subsidiaries"). The Company and each of its
            Subsidiaries is, and at the Closing Date will be, a corporation,
            limited liability company, general partnership or limited
            partnership duly organized, validly existing and in good standing
            under the laws of its jurisdiction of incorporation or organization.
            The Company and each of its Subsidiaries have, and at the Closing
            Date will have, full power and authority to conduct all the
            activities conducted by it, to own or lease all the assets owned or
            leased by it and to conduct its business as described in the
            Registration Statement and the Prospectus. The Company and each of
            its Subsidiaries is, and at the Closing Date will be, duly licensed
            or qualified to do business and in good standing as a foreign
            corporation, limited liability company, general partnership or
            limited partnership in all jurisdictions in which the nature of the
            activities conducted by it or the character of the assets owned or
            leased by it makes such licensing or qualification necessary, except
            to the extent that the failure to so qualify or be in good standing
            would not have a material adverse effect on the condition (financial
            or otherwise), earnings, cash flow, business affairs or business
            prospects of the Company and its Subsidiaries, considered as one
            enterprise (a "Material Adverse Effect"). Except as set forth on
            Schedule II hereto, all of the outstanding shares of capital stock,
            capital interests or

                                        6



            partnership interests of the Subsidiaries have been duly authorized
            and validly issued and, as to capital stock, are fully paid and
            non-assessable, and are owned by the Company free and clear of all
            security interests, liens, encumbrances and claims whatsoever.
            Except for (i) the stock of or interests in the Subsidiaries
            disclosed on Schedule II hereto and (ii) as disclosed in the
            Registration Statement and the Prospectus, the Company does not own,
            and at the Closing Date will not own, directly or indirectly, any
            shares of stock or any other equity or long-term debt securities of
            any corporation or have any equity interest in any firm,
            partnership, joint venture, association or other entity. Complete
            and correct copies of the certificate of incorporation and of the
            by-laws or other organizational documents of the Company and each of
            its significant subsidiaries (as defined in Rule 1-02(w) of
            Regulation S-X of the Rules and Regulations) and all amendments
            thereto have been delivered to the Underwriters, and no changes
            therein will be made subsequent to the date hereof and prior to the
            Closing Date or, if later, the Option Closing Date, except that the
            Company may file a Certificate of Designations with the Secretary of
            State of the State of Oklahoma related to the Series D Convertible
            Preferred Stock of the Company as contemplated by the Transaction
            Agreement, dated as of January 9, 2003 (the "Transaction
            Agreement"), among the Company, Westar Energy, Inc., a Kansas
            corporation, and Westar Industries, Inc., a Delaware corporation.

     (e)           None of the Subsidiaries is currently prohibited, directly or
            indirectly, from paying any dividends to the Company, from making
            any other distribution on such Subsidiary's capital stock, from
            repaying to the Company any loans or advances to such Subsidiary
            from the Company or from transferring any of such Subsidiary's
            property or assets to the Company or any other Subsidiary, except as
            described or contemplated by the Registration Statement and the
            Prospectus.

     (f)           The outstanding shares of Common Stock have been, and the
            Shares to be issued and sold by the Company upon such issuance will
            be, duly authorized, validly issued, fully paid and nonassessable
            and will not be subject to any preemptive or similar right. The
            description of the Common Stock in the Registration Statement and
            the Prospectus is, and at the Closing Date and the Option Closing
            Date, as applicable, will be, complete and accurate in all respects.
            Except (i) as set forth in the Registration Statement and the
            Prospectus and (ii) with respect to (A) stock options or other
            employee and director compensation arrangements pursuant to the
            terms of a plan in effect on the date of this Agreement or (B)
            direct stock purchase or dividend investment plans in place on the
            date of this Agreement, the Company does not have outstanding, and
            at the Closing Date and the Option Closing Date, as applicable, will
            not have outstanding, any options to purchase, or any rights or
            warrants to subscribe for, or any securities or obligations
            convertible into, or any contracts or commitments to issue or sell,
            any shares of Common Stock, any shares of capital stock of any
            Subsidiary or any such warrants, convertible securities or

     (g)           The financial statements and schedules included or
            incorporated by reference in the Registration Statement or the
            Prospectus, and any amendment or supplement thereto, present fairly
            the consolidated financial condition of the Company, as of the date
            thereof and the consolidated results of operations and cash flows of
            the Company for the period covered thereby, in conformity with
            generally accepted accounting principles applied on a consistent
            basis throughout the entire period involved. KPMG LLP (the
            "Accountant"), the accounting firm that has certified the financial
            statements and schedules included or incorporated by reference in
            the Registration Statement or the Prospectus, and any amendment or
            supplement thereto, is an independent public accounting firm within
            the meaning of the Act and the Rules and Regulations and the
            Accountant is not in violation of the auditor independence
            requirements of Section 201 of the Sarbanes-Oxley Act of 2002 (the
            "Sarbanes-Oxley Act") with respect to the Company. There are no pro
            forma financial statements or other pro forma financial information
            required to be included or incorporated by reference in the
            Registration Statement or the Prospectus. No other financial
            statements or schedules of the Company are required by the Act, the
            Exchange Act or the Rules and Regulations to be included or
            incorporated by reference in the Registration Statement or the
            Prospectus. The financial data set forth in the Prospectus under the
            captions "Summary- Summary Consolidated Financial Data" and
            "Capitalization" fairly present the information set forth therein on
            a basis consistent with that of the audited financial statements
            incorporated by reference in the Registration Statement. The
            Company's ratios of earnings to fixed charges and earnings to
            combined fixed charges and preferred stock dividend requirements set
            forth in the Prospectus under the captions "Summary- Summary
            Consolidated Financial Data," "Ratio of Earnings to Fixed Charges"
            and "Ratio of Earnings to Combined Fixed Charges and Preferred Stock
            Dividend Requirements" and in Exhibits 12.1 and 12.2 to the
            Registration Statement have been calculated in compliance with Item
            503(d) of Regulation S-K under the Act.

     (h)           The books, records and accounts of the Company and its
            Subsidiaries accurately and fairly reflect, in reasonable detail,
            the transactions in and dispositions of the assets of the Company
            and its Subsidiaries. The Company and each of its Subsidiaries
            maintain an adequate internal control structure, procedures for
            financial reporting and a system of internal accounting control
            sufficient to provide reasonable assurance that (i) transactions are
            executed in accordance with management's general or specific
            authorization; (ii) transactions are recorded as necessary to permit
            the preparation of the Company's consolidated financial statements
            in conformity with generally accepted accounting principles and to
            maintain accountability for the assets of the Company and its
            Subsidiaries; (iii) access to the assets of the Company and its
            Subsidiaries is permitted only in accordance with management's
            general or specific authorization; and (iv) the recorded accounts of
            the assets of the Company and its Subsidiaries is compared with
            existing assets at reasonable intervals and appropriate action is
            taken with respect to any differences.

                                        8



     (i)           Subsequent to the respective dates as of which information is
            given in the Registration Statement and the Prospectus and prior to
            the Closing Date and the Option Closing Date, as applicable, except
            as set forth in or contemplated by the Registration Statement and
            the Prospectus, (i) there has not been and will not have been any
            material change in the capitalization of the Company, or in the
            business, properties, business prospects, condition (financial or
            otherwise) or results of operations of the Company and its
            Subsidiaries arising for any reason whatsoever, (ii) neither the
            Company nor any of its Subsidiaries has incurred nor will it incur
            any material liabilities or obligations, direct or contingent nor
            has it entered into nor will it enter into any material transactions
            other than pursuant to this Agreement and the transactions referred
            to herein and (iii) the Company has not and will not have paid or
            declared any dividends or other distributions of any kind on any
            class of its capital stock, other than the ordinary quarterly
            dividend paid or payable by the Company to holders of the Common
            Stock and preferred stock consistent with past practices.

     (j)           The Company is not an "investment company" or a company
            "controlled by" or an "affiliated person" of, or "promoter" or
            "principal underwriter" for, an "investment company," as such terms
            are defined in the Investment Company Act of 1940, as amended (the
            "Investment Company Act"). After receipt of the payment for the
            Shares, the Company will not be an "investment company" within the
            meaning of the Investment Company Act and will conduct its business
            in a manner so that it will not become subject to the Investment
            Company Act.

     (k)           Except as set forth in the Registration Statement and the
            Prospectus, there are no actions, suits or proceedings pending or
            threatened against or affecting the Company or any of its
            Subsidiaries or any of their respective directors or officers in
            their capacity as such, before or by any federal or state court,
            commission, regulatory body, administrative agency or other
            governmental body, domestic or foreign, wherein an unfavorable
            ruling, decision or finding would have a Material Adverse Effect.

     (l)           The Company and each of its Subsidiaries has, and at the
            Closing Date and the Option Closing Date, as applicable, will have,
            (i) all governmental licenses, permits, consents, orders, approvals
            and other authorizations (collectively, "Governmental Licenses")
            necessary to carry on its business as contemplated in the
            Prospectus, except for the Governmental Licenses the absence of
            which would not have a Material Adverse Effect, (ii) complied in all
            material respects with all laws, regulations and orders applicable
            to it or its business, including the Sarbanes-Oxley Act, other than
            noncompliance that would not, individually or in the aggregate,
            result in a Material Adverse Effect, and (iii) performed all its
            obligations required to be performed by it, and is not, and at the
            Closing Date and the Option Closing Date, as applicable, will not
            be, in default, under any indenture, mortgage, deed of trust, voting
            trust agreement, loan agreement, bond, debenture, note agreement,
            lease, contract or other agreement or instrument (collectively, a
            "contract or other agreement") to which it is a party or by which
            its

                                        9



            property is bound or affected, other than defaults that would not,
            individually or in the aggregate, result in a Material Adverse
            Effect. To the knowledge of the Company and each of its
            Subsidiaries, except as described in the Registration Statement and
            the Prospectus, no other party under any material contract or other
            agreement to which it is a party is in material default in any
            respect thereunder. Neither the Company nor any of its Subsidiaries
            is, nor at the Closing Date or the Option Closing Date, as
            applicable, will any of them be, in violation of any provision of
            its certificate of incorporation, by-laws or other organizational
            documents.

     (m)           No consent, approval, authorization or order of, or any
            filing or declaration with, any court or governmental agency or body
            is required in connection with the authorization, issuance,
            transfer, sale or delivery of the Shares by the Company, in
            connection with the execution, delivery and performance of this
            Agreement by the Company or in connection with the taking by the
            Company of any action contemplated hereby, except such (i) as have
            been obtained under the Act or the Rules and Regulations, (ii) as
            may be required under state securities or Blue Sky laws or the
            by-laws and rules of the National Association of Securities Dealers,
            Inc. (the "NASD") in connection with the purchase and distribution
            by the Underwriters of the Shares and (iii) that the failure to
            obtain would not result in a Material Adverse Effect.

     (n)           The Company has full corporate power and authority to enter
            into this Agreement and the Transaction Agreement and to perform its
            obligations under this Agreement and the Transaction Agreement. This
            Agreement and the Transaction Agreement have been duly authorized,
            executed and delivered by the Company and constitute legal, valid
            and binding obligations of the Company, enforceable against the
            Company in accordance with the terms hereof and thereof, subject to
            the effect of bankruptcy, insolvency, reorganization, receivership,
            moratorium and other laws affecting the rights and remedies of
            creditors generally and general equitable principles and subject to
            any principles of public policy limiting the rights to enforce any
            indemnification provisions contained herein and therein. The
            performance of this Agreement and the Transaction Agreement and the
            consummation of the transactions contemplated hereby and thereby and
            the application of the net proceeds from the offering and sale of
            the Shares in the manner set forth in the Prospectus under "Use of
            Proceeds" will not result in the creation or imposition of any lien,
            charge or encumbrance upon any of the assets of the Company or any
            of its Subsidiaries pursuant to the terms or provisions of, or
            result in a breach or violation of any of the terms or provisions
            of, or constitute a default under, or give any other party a right
            to terminate any of its obligations under, or result in the
            acceleration of any obligation under, the certificate of
            incorporation or by-laws of the Company or any of its Subsidiaries,
            any material contract or other agreement to which the Company or any
            of its Subsidiaries is a party or by which the Company or any of its
            Subsidiaries or any of its properties is bound or affected, or
            violate or conflict with any judgment, ruling, decree, order,

                                       10



            statute, rule or regulation of any court or governmental agency or
            body applicable to the business or properties of the Company or any
            of its Subsidiaries.

     (o)           The Company and each of its Subsidiaries has good and valid
            title to all properties and assets described in the Prospectus as
            owned by it, free and clear of all liens, charges, encumbrances or
            restrictions, except such as are described in the Prospectus or
            would not have a Material Adverse Effect. The Company and each of
            its Subsidiaries have valid, subsisting and enforceable leases for
            the properties described in the Prospectus as leased by it, with
            such exceptions as are not material and do not materially interfere
            with the use made and proposed to be made of such properties by the
            Company and such Subsidiaries.

     (p)           All legal or governmental proceedings, affiliate
            transactions, contracts, licenses, agreements, leases or documents
            of a character required to be described in the Registration
            Statement or the Prospectus or to be filed as an exhibit to the
            Registration Statement have been so described or filed as required.
            All such contracts to which the Company or any Subsidiary is a party
            have been duly authorized, executed and delivered by the Company or
            such Subsidiary, constitute valid and binding agreements of the
            Company or such Subsidiary and are enforceable against the Company
            or such Subsidiary in accordance with the terms thereof, subject to
            the effect of bankruptcy, insolvency, reorganization, receivership,
            moratorium and other laws affecting the rights and remedies of
            creditors generally and general equitable principles and subject to
            any principles of public policy limiting the rights to enforce any
            indemnification provisions contained herein and therein.

     (q)           No statement, representation, warranty or covenant made by
            the Company in this Agreement or made in any certificate or document
            required by this Agreement to be delivered to the Underwriters was
            or will be, when made, inaccurate, untrue or incorrect in any
            material respect. Any certificate signed by any officer of the
            Company and delivered to the Underwriters or counsel for the
            Underwriters in connection with the offering of the Shares shall be
            deemed a representation and warranty by the Company to the
            Underwriters as to the matters covered thereby.

     (r)           Neither the Company nor any of its Subsidiaries or any of
            their respective directors, officers, affiliates or controlling
            persons has taken, directly or indirectly, any action designed, or
            that might reasonably be expected, to cause or result, under the
            Exchange Act or otherwise, in, or which has constituted,
            stabilization or manipulation of the price of any security of the
            Company to facilitate the sale or resale of the Shares.

     (s)           No holder of securities of the Company has rights to the
            registration of any securities of the Company because of the filing
            of the Registration Statement or the consummation of the
            transactions contemplated by this Agreement.

                                       11



     (t)           The Shares have been approved for listing on the New York
            Stock Exchange, subject only to official notice of issuance.

     (u)           The Company and its Subsidiaries are in substantial
            compliance with all federal, state and local employment and labor
            laws, including, but not limited to, laws relating to
            non-discrimination in hiring, promotion and pay of employees; no
            labor dispute with the employees of the Company or any Subsidiary
            exists or, to the knowledge of the Company, is imminent or
            threatened; and the Company is not aware of any existing, imminent
            or threatened labor disturbance by the employees of any of its
            principal suppliers, manufacturers or contractors that could result
            in a Material Adverse Effect.

     (v)           The Company and its Subsidiaries own, or are licensed or
            otherwise have the full exclusive right to use, all material
            trademarks, service marks and trade names that are used in or
            necessary for the conduct of their respective businesses as
            described in the Prospectus, except for failures of ownership or use
            that would not cause a Material Adverse Effect. To the knowledge of
            the Company, no claims have been asserted by any person to the use
            of any such trademarks or trade names or challenging or questioning
            the validity or effectiveness of any such trademark or trade name.
            The use, in connection with the business and operations of the
            Company and its Subsidiaries of such trademarks and trade names does
            not, to the Company's knowledge, infringe on the rights of any
            person.

     (w)           Neither the Company nor any of its Subsidiaries nor, to the
            Company's knowledge, any employee or agent of the Company or any
            Subsidiary has made any payment of funds of the Company or any
            Subsidiary or received or retained any funds in violation of any
            law, rule or regulation or of a character required to be disclosed
            in the Prospectus.

     (x)           All United States federal income tax returns of the Company
            and its Subsidiaries required by law to be filed have been filed or
            extensions have been granted, and all other franchise and income tax
            returns of the Company and its Subsidiaries required to be filed
            pursuant to applicable foreign, state or local law have been filed,
            and all taxes shown by such returns or otherwise assessed, which are
            due and payable, have been paid, except tax assessments, if any, as
            are being contested in good faith and as to which adequate reserves
            have been provided and taxes that are currently payable without
            penalty or interest. The charges, accruals and reserves on the books
            of the Company and its Subsidiaries in respect of any income and
            corporate franchise tax liability for any years not finally
            determined are adequate to meet any assessments or reassessments for
            additional income or corporate franchise tax for any years not
            finally determined.

     (y)           The Company and its Subsidiaries (i) are in compliance with
            any and all applicable foreign, federal, state and local laws and
            regulations relating to the protection of human health and safety,
            the environment or imposing liability or standards of conduct
            concerning any Hazardous Material (as hereinafter defined)

                                       12



            ("Environmental Laws"), (ii) have received all permits, licenses or
            other approvals required of them under applicable Environmental Laws
            to conduct their respective businesses and (iii) are in compliance
            with all terms and conditions of any such permit, license or
            approval, except as set forth in the Registration Statement and the
            Prospectus and except where such noncompliance with Environmental
            Laws, failure to receive required permits, licenses or other
            approvals or failure to comply with the terms and conditions of such
            permits, licenses or approvals would not, individually or in the
            aggregate result in a Material Adverse Effect. The term "Hazardous
            Material" means (A) any "hazardous substance" as defined by the
            Comprehensive Environmental Response, Compensation and Liability Act
            of 1980, as amended, (B) any "hazardous waste" as defined by the
            Resource Conservation and Recovery Act, as amended, (C) any
            petroleum or petroleum product, (D) any polychlorinated biphenyl and
            (E) any pollutant or contaminant or hazardous, dangerous, or toxic
            chemical, material, waste or substance regulated under or within the
            meaning of any other Environmental Law.

     (z)           In the ordinary course of its business, the Company conducts
            a periodic review of the effect of Environmental Laws on the
            business, operations and properties of the Company and its
            Subsidiaries, in the course of which it identifies and evaluates
            associated costs and liabilities (including, without limitation, any
            capital or operating expenditures required for clean-up, closure of
            properties or compliance with Environmental Laws or any permit,
            license or approval, any related constraints on operating activities
            and any potential liabilities to third parties). Except as set forth
            in the Registration Statement and the Prospectus there are no costs
            and liabilities associated with or arising in connection with
            Environmental Laws as currently in effect (including, without
            limitation, costs of compliance therewith) which would, singly or in
            the aggregate have a Material Adverse Effect.

     (aa)          Except as disclosed in the Registration Statement and the
            Prospectus, neither the Company nor any of its Subsidiaries has
            received any written communication, whether from a governmental
            authority, citizens' group, employee or otherwise, asserting that
            the Company or any of its Subsidiaries or any other person or entity
            for whom any of them is or may be liable is not in compliance with
            any Environmental Laws or permit or authorization required under
            applicable Environmental Laws where such failure to comply would
            have a Material Adverse Effect, and, to the knowledge of the
            Company, there are no circumstances that may prevent or interfere
            with such full compliance in the future, except where failure so to
            comply would not have a Material Adverse Effect.

     (bb)          The Company has obtained for the benefit of the Underwriters
            the agreement (a "Lock-Up Agreement"), of each of the Company's
            directors and executive officers. The Company will not release or
            purport to release any person from any Lock-Up Agreement without the
            prior written consent of the Representatives.

                                       13



     (cc)          The Company and each of its Subsidiaries maintains insurance
            covering its properties, operations, personnel and businesses as the
            Company deems adequate. Such insurance insures against such losses
            and risks to an extent which is adequate in accordance with
            customary industry practice to protect the Company and its
            subsidiaries and their businesses. All such insurance is outstanding
            and fully in force on the date hereof and will be outstanding and

            respective business from fire, explosion, flood or other calamity,
            whether or not covered by insurance, or from any labor dispute or
            court or governmental action, order or decree.

            Security Act of 1974, as amended ("ERISA")) maintained or
            contributed to by the Company, or with respect to which the Company
            could incur any liability under ERISA (collectively, the "Benefit
            Plans"), no event has occurred and, to the knowledge of the Company,
            there exists no condition or set of circumstances, in connection
            with which the Company could be subject to any liability under the
            terms of such Benefit Plan, applicable law (including, without
            limitation, ERISA and the Internal Revenue Code of 1986, as amended)

            Material Adverse Effect.

            under which no new loans have been made since the enactment of the
            Sarbanes-Oxley Act), advances (except normal advances for business
            expenses in the ordinary course of business) or guarantees of
            indebtedness by the Company to or for the benefit of any of the

            journalist or publication to write or publish favorable information
            about the Company or any of the subsidiaries or any of their
            respective products or services.

            provisions of the Sarbanes-Oxley Act that are effective and is
            actively taking steps to ensure that it will be in compliance with

4.          Agreements of the Company.  The Company agrees with each Underwriter
     as follows:

     (a)           The Company will not, during such period as the Prospectus is
            required by law to be delivered in connection with sales of the
            Shares by an Underwriter or a dealer (the "Prospectus Delivery
            Period"), file any amendment or supplement to the Registration
            Statement or the Prospectus, unless a copy thereof shall first have
            been submitted to the Underwriters within a reasonable period of
            time prior to the filing thereof and the Underwriters shall not have
            objected thereto in good faith.

     (b)           The Company will notify the Underwriters promptly, and will
            confirm such advice in writing, (i) when any post-effective
            amendment to the Registration Statement becomes effective, (ii) of
            any request by the Commission for amendments or supplements to the
            Registration Statement or the Prospectus or for additional
            information, (iii) of the issuance by the Commission of any stop
            order suspending the effectiveness of the Registration Statement or
            the initiation of any proceedings for that purpose or the threat
            thereof, (iv) of the happening of any event during the period
            mentioned in the second sentence of Section 4(e) that in the
            judgment of the Company makes any statement made in the Registration
            Statement or the Prospectus untrue or that requires the making of
            any changes in the Registration Statement or the Prospectus in order
            to make the statements therein, in light of the circumstances in
            which they are made, not misleading and (v) of receipt by the
            Company or any representative or attorney of the Company of any
            other communication from the Commission relating to the Company, the

                                       15



            Registration Statement, any preliminary prospectus or the
            Prospectus. If at any time the Commission shall issue any order
            suspending the effectiveness of the Registration Statement, the
            Company will make every reasonable effort to obtain the withdrawal
            of such order at the earliest possible moment. The Company will use
            its best efforts to comply with the provisions of and make all
            requisite filings with the Commission pursuant to Rule 430A and to
            notify the Underwriters promptly of all such filings.

     (c)           The Company has furnished, or will furnish, to the
            Underwriters, without charge, two conformed copies of the
            Registration Statement and of any post-effective amendment thereto,
            including financial statements and schedules, and all exhibits
            thereto (including any document filed under the Exchange Act and
            deemed to be incorporated by reference into the Prospectus).

     (d)           The Company will comply with all the provisions of any
            undertakings contained in the Registration Statement.

     (e)           On the Effective Date, and thereafter from time to time, the
            Company will deliver to the Representatives, without charge, as many
            copies of the Prospectus or any amendment or supplement thereto as
            the Representatives may reasonably request. The Company consents to
            the use of the Prospectus or any amendment or supplement thereto by
            the Underwriters and by all dealers to whom the Shares may be sold,
            both in connection with the offering or sale of the Shares and
            during the Prospectus Delivery Period. If, during the Prospectus
            Delivery Period any event shall occur that in the judgment of the
            Company or counsel to the Underwriters should be set forth in the
            Prospectus in order to make any statement therein, in the light of
            the circumstances under which it was made, not misleading, or if it
            is necessary to supplement or amend the Prospectus to comply with
            law, the Company will forthwith prepare and duly file with the
            Commission an appropriate supplement or amendment thereto, and will
            deliver to the Representatives, without charge, such number of
            copies thereof as the Representatives may reasonably request. The
            Company shall not file any document under the Exchange Act before
            the termination of the offering of the Shares by the Underwriters if
            such document would be deemed to be incorporated by reference into
            the Prospectus and if such document is not approved by the
            Representatives after reasonable notice thereof.

     (f)           Prior to any public offering of the Shares by the
            Underwriters, the Company will cooperate with the Representatives
            and counsel to the Underwriters in connection with the registration
            or qualification of the Shares for offer and sale under the
            securities or Blue Sky laws of such jurisdictions as the
            Representatives may request; provided, that in no event shall the
            Company be obligated to qualify to do business in any jurisdiction
            where it is not now so qualified or to take any action which would
            subject it to general service of process in any jurisdiction where
            it is not now so subject.

                                       16



     (g)           During the period of two years commencing on the date of the

            periodic and special reports as the Company may from time to time

            stock, and will furnish to the Representatives a copy of each annual

            securities as soon as may be practicable but in no event later than
            the last day of the 15th full calendar month following the calendar

            the provisions of Section 11(a) of the Act (including Rule 158 of
            the Rules and Regulations).

            Agreement are consummated or this Agreement is terminated, the
            Company will pay, or reimburse if paid by the Underwriters, all

            requested for use in connection with the offering and sale of the

            any filings required to be made by the Underwriters with the NASD,
            and the reasonable fees, disbursements and other charges of counsel
            to the Underwriters in connection therewith, (vii) the registration
            or qualification of the Shares for offer and sale under the
            securities or Blue Sky laws of such jurisdictions designated

            cause or result in, or which will constitute, stabilization of the
            price of the shares of Common Stock to facilitate the sale or resale
            of any of the Shares.

                                       17



     (k)           The Company will apply the net proceeds from the offering and
            sale of the Shares to be sold by the Company in the manner set forth
            in the Prospectus under "Use of Proceeds." The Company shall not
            invest, or otherwise use the proceeds received by the Company from
            its sale of the Shares in such a manner as would require the Company
            or any of its Subsidiaries to register as an investment company
            under the Investment Company Act.

     (l)           The Company shall cause to be prepared and delivered, at its

            form of Prospectus, and any amendment or supplement thereto, that
            meets each of the following conditions: (i) it shall be encoded in
            an electronic format, satisfactory to the Representatives, that may
            be transmitted electronically by the Representatives and the other
            Underwriters to offerees and purchasers of the Shares for at least
            the Prospectus Delivery Period; (ii) it shall disclose the same
            information as the paper Prospectus and Prospectus filed pursuant to
            EDGAR, except to the extent that graphic and image material cannot
            be disseminated electronically, in which case such graphic and image
            material shall be replaced in the electronic Prospectus with a fair
            and accurate narrative description or tabular representation of such
            material, as appropriate; and (iii) it shall be in or convertible
            into a paper format or an electronic format, satisfactory to the
            Representatives, that will allow investors to store and have
            continuously ready access to the Prospectus at any future time,
            without charge to investors (other than any fee charged for
            subscription to the Internet as a whole and for on-line time). The
            Company hereby confirms that it has included or will include in the
            Prospectus filed pursuant to EDGAR or otherwise with the Commission
            and in the Registration Statement at the time it was declared
            effective an undertaking that, upon receipt of a request by an
            investor or his or her representative within the Prospectus Delivery
            Period, the Company shall transmit or cause to be transmitted
            promptly, without charge, a paper copy of the Prospectus.

     (m)           During the 90-day period beginning on the date of this
            Agreement, the Company will not without the prior written consent of
            the Representatives (which consent may be withheld at the sole
            discretion of the Representatives), directly or indirectly, sell,
            offer, contract or grant any option to sell, pledge, transfer or
            establish an open "put equivalent position" within the meaning of
            Rule 16a-1(h) under the Exchange Act, or otherwise dispose of or
            transfer, or file with the Commission a registration statement under
            the Act relating to, any shares of Common Stock or securities
            convertible into or exchangeable for any shares of Common Stock, or
            publicly disclose the intention to make any such offer, sale,
            pledge, transfer, disposition or filing, except for (i) issuances
            pursuant to employee or director compensation plans existing on the

            purchase plans in existence on the date of this Agreement, (v) the
            filing of registration statements in connection with any exercise by
            Westar Energy, Inc. or Westar Industries, Inc. of their demand
            registration rights, (vi) the filing of an amendment to the
            Company's Form 8-A registration statement relating to the preferred

            purchase or dividend reinvestment plans in place on the date of this
            Agreement, (viii) the issuance of shares of Common Stock or options
            in acquisitions in which the acquiror of such shares or options
            agrees to the foregoing restrictions and (ix) the issuance of shares
            of the Company's Series D Convertible Preferred Stock as
            contemplated by the Transaction Agreement.

     (n)           The Company has engaged and shall maintain, at its expense, a
            registrar and transfer agent for the Common Stock.

     (o)           The Company and its Subsidiaries will keep and maintain
            books, records and accounts that accurately and fairly reflect, in
            reasonable detail, transactions in and dispositions of the assets of
            the Company and its Subsidiaries. The Company and each of its
            Subsidiaries will maintain an adequate internal control structure,
            procedures for financial reporting and a system of internal
            accounting control sufficient to provide reasonable assurance that
            (i) transactions are executed in accordance with management's
            general or specific authorization, (ii) transactions are recorded as
            necessary to permit the preparation of the Company's consolidated

            of the Company and its Subsidiaries, (iii) access to the assets of
            the Company and its Subsidiaries is permitted only in accordance
            with management's general or specific authorization and (iv) the
            recorded accounts of the assets of the Company and its Subsidiaries
            are compared with existing assets at reasonable intervals and
            appropriate action is taken with respect to any differences.

     (p)           The Company and its Subsidiaries will maintain such controls
            and other procedures, including without limitation, those required
            by Sections 302 and 906 of the Sarbanes-Oxley Act and the applicable
            regulations thereunder, that are designed to ensure that information
            required to be disclosed by the Company in the reports that it files

            and reported within the time periods specified in the Commission's
            rules and forms, including, without limitation, controls and
            procedures designed to ensure that information required to be
            disclosed by the Company in the reports that it files or submits
            under the Exchange Act is accumulated and communicated to the
            Company's management, including its Chief Executive Officer or
            officers and Principal Financial Officer or officers, or persons
            performing similar functions, as appropriate, to allow timely
            decisions regarding required disclosure

            and to ensure that material information relating to the Company,
            including its Subsidiaries, is made known to them by others within
            those entities, particularly during the period in which such
            periodic reports are being prepared.

     (q)           The Company and its Subsidiaries will take all such steps as
            may be necessary to enable it to be in substantial compliance with
            all effective applicable provisions of the Sarbanes-Oxley Act.

5.          Conditions of the Obligations of the Underwriters. In addition to
     the execution and delivery of the Price Determination Agreement, the
     obligations of each Underwriter hereunder are subject to the following
     conditions:

     (a)           (i) No stop order suspending the effectiveness of the
            Registration Statement shall have been issued and no proceedings for
            that purpose shall be pending or threatened by the Commission, (ii)
            no order suspending the effectiveness of the Registration Statement
            or the qualification or registration of the Shares under the
            securities or Blue Sky laws of any jurisdiction shall be in effect
            and no proceeding for such purpose shall be pending before or
            threatened or contemplated by the Commission or the authorities of
            any such jurisdiction, (iii) any request for additional information
            on the part of the staff of the Commission or any such authorities
            shall have been complied with to the satisfaction of the staff of
            the Commission or such authorities and (iv) after the date hereof no
            amendment or supplement to the Registration Statement or the
            Prospectus shall have been filed unless a copy thereof was first
            submitted to the Underwriters and the Underwriters did not object
            thereto in good faith, and the Underwriters will have received
            certificates, dated the Closing Date and the Option Closing Date, as
            applicable, and signed by the Chief Executive Officer, President or
            a Vice President of the Company and the Chief Financial Officer of
            the Company (who may, as to proceedings threatened, rely upon the
            best of their information and belief), to the effect of clauses (i),
            (ii) and (iii).

     (b)           Since the respective dates as of which information is given
            in the Registration Statement and the Prospectus (i) there shall not
            have been a material adverse change in the general affairs,
            business, business prospects, properties, management, condition
            (financial or otherwise) or results of operations of the Company and
            its Subsidiaries, taken as a whole, whether or not arising from
            transactions in the ordinary course of business, in each case other
            than as set forth in or contemplated by the Registration Statement
            and the Prospectus and (ii) neither the Company nor any of its
            Subsidiaries shall have sustained any material loss or interference
            with its business or properties from fire, explosion, flood or other
            casualty, whether or not covered by insurance, or from any labor
            dispute or any court or legislative or other governmental action,
            order or decree, which is not set forth in the Registration
            Statement and the Prospectus, and in your judgment makes it
            impracticable or inadvisable to consummate the sale and delivery of
            the Shares by the Underwriters in accordance with the terms hereof
            and thereto.

                                       20



     (c)           Since the respective dates as of which information is given
            in the Registration Statement and the Prospectus, there shall have
            been no litigation or other proceeding instituted against the
            Company or any of its Subsidiaries or any of their respective
            officers or directors in their capacities as such, before or by any
            federal, state or local court, commission, regulatory body,
            administrative agency or other governmental body, domestic or
            foreign, in which litigation or proceeding an unfavorable ruling,
            decision or finding would materially and adversely affect the
            business, properties, business prospects, condition (financial or
            otherwise) or results of operations of the Company and its
            Subsidiaries taken as a whole.

     (d)           Each of the representations and warranties of the Company
            contained herein shall be true and correct in all material respects
            at the Closing Date and, with respect to the Option Shares, at the
            Option Closing Date, as if made at the Closing Date, and all
            covenants and agreements herein contained to be performed on the
            part of the Company and all conditions herein contained to be
            fulfilled or complied with by the Company at or prior to the Closing
            Date and, with respect to the Option Shares, at or prior to the
            Option Closing Date, shall have been duly performed, fulfilled or
            complied with.

     (e)           The Representatives will have received opinions, each dated
            the Closing Date and, with respect to the Option Shares, the Option
            Closing Date, and satisfactory in form and substance to counsel to
            the Underwriters, from (i) Gable & Gotwals, counsel to the Company,
            to the effect set forth in Exhibit B, (ii) Andersen, Byrd, Richeson,
            Flaherty and Henrichs, special Kansas counsel to the Company, and
            (iii) Patman & Osborn, special Texas counsel to the Company.

     (f)           The Representatives will have received an opinion, dated the
            Closing Date and the Option Closing Date, from Jones Day, counsel to
            the Underwriters, with respect to the Registration Statement, the
            Prospectus and this Agreement, which opinion shall be satisfactory
            in all respects to the Representatives.

     (g)           On the date of the Prospectus, the Accountant shall have
            furnished to the Representatives a letter, dated the date of its
            delivery, addressed to the Representatives and in form and substance
            satisfactory to the Representatives, containing statements and
            information of the type ordinary include in accountant's "comfort
            letters" to underwriters, delivered according to Statement of
            Accounting Standards No. 72 (or any successor bulletin), with
            respect to the audited and unaudited financial statements and
            certain financial and other statistical and numerical information
            contained or incorporated by reference in the Registration Statement
            and the Prospectus. At the Closing Date and, as to the Option
            Shares, the Option Closing Date, the Accountant shall have furnished
            to the Representatives a letter, dated the date of its delivery,
            which shall confirm, on the basis of a review in accordance with the
            procedures set forth in the letter from the Accountant, that nothing
            has come to their attention during the period from the date of the
            letter referred to in the prior sentence to a date (specified in the
            letter) not more than three days prior to the Closing Date and the
            Option Closing Date

                                       21



            that would require any change in their letter dated the date of the
            Prospectus, if it were required to be dated and delivered at the
            Closing Date and the Option Closing Date.

     (h)           At the Closing Date and, as to the Option Shares, the Option
            Closing Date, there shall be furnished to each Underwriter an
            accurate certificate, dated the date of its delivery, signed by each
            of the Chief Executive Officer, President or a Vice President and
            the Chief Financial Officer of the Company, in form and substance
            satisfactory to the Underwriters, to the effect that:

            (i)           each signer of such certificate has reviewed the
                   Registration Statement and the Prospectus (including any
                   documents filed under the Exchange Act and deemed to be
                   incorporated by reference into the Prospectus) and (A) as of
                   the date of such certificate, such documents are true and
                   correct in all material respects and do not omit to state a
                   material fact required to be stated therein or necessary in
                   order to make the statements therein not untrue or misleading
                   and (B) since the Effective Date, no event has occurred as a
                   result of which it is necessary to amend or supplement the
                   Prospectus in order to make the statements therein not untrue
                   or misleading in any material respect and there has been no
                   document required to be filed under the Exchange Act and the
                   Exchange Act Rules and Regulations that upon such filing
                   would be deemed to be incorporated by reference into the
                   Prospectus that has not been so filed;

            (ii)          each of the representations and warranties of the
                   Company contained in this Agreement were, when originally
                   made, and are, at the time such certificate is delivered,
                   true and correct in all material respects; and

            (iii)         each of the covenants required herein to be performed
                   by the Company on or prior to the delivery of such
                   certificate has been duly, timely and fully performed and
                   each condition herein required to be complied with by the
                   Company on or prior to the date of such certificate has been
                   duly, timely and fully complied with.

     (i)           On or prior to the Closing Date, the Representatives will
            have received executed Lock-Up Letter Agreements, in the form of
            Exhibit C hereto, from the Company's directors and executive
            officers.

     (j)           The Shares will be qualified for sale in such states as the
            Underwriters may reasonably request, each such qualification shall
            be in effect and not subject to any stop order or other proceeding
            on the Closing Date or the Option Closing Date.

     (k)           Subsequent to the execution and delivery of this Agreement
            and prior to the Closing Date or the Option Closing Date, as the
            case may be, there shall not

                                       22



            have been any downgrading, nor any notice given of any intended or
            potential downgrading or of a possible change that does not indicate
            the direction of the possible change, in the rating accorded any of
            the Company's securities by any "nationally recognized statistical
            rating organization," as such term is defined for purposes of Rule
            436(g)(2) under the Act.

     (l)           The Shares shall have been approved for listing on the New
            York Stock Exchange, subject only to official notice of issuance.

     (m)           The Company shall have furnished to the Representatives such
            certificates, in addition to those specifically mentioned herein, as
            the Representatives may have reasonably requested as to the accuracy
            and completeness at the Closing Date and the Option Closing Date of
            any statement in the Registration Statement or the Prospectus or any
            documents filed under the Exchange Act and deemed to be incorporated
            by reference into the Prospectus, as to the accuracy at the Closing
            Date and the Option Closing Date of the representations and
            warranties of the Company herein, as to the performance by the
            Company of its obligations hereunder, or as to the fulfillment of
            the conditions concurrent and precedent to the obligations hereunder
            of each Underwriter.

            If any condition specified in this Section 5 is not satisfied when
and as required to be satisfied, this Agreement may be terminated by the
Representatives by notice to the Company at any time on or prior to the Closing
Date and, with respect to the Option Shares, at any time prior to the Option
Closing Date, which termination shall be without liability on the part of any
party to any other party, except that Section 4, Section 6, Section 8 and
Section 11 shall at all times be effective and shall survive such termination.

6.          Reimbursement of Underwriters' Expenses. If this Agreement is
     terminated by the Representatives pursuant to Section 5, Section 7, Section
     9 or Section 10, or if the sale to the Underwriters of the Firm Shares on
     the Closing Date is not consummated because of any refusal, inability or
     failure on the part of the Company to perform any agreement herein or to
     comply with any provision hereof, the Company agrees to reimburse the
     Representatives and the other Underwriters (or such Underwriters as have
     terminated this Agreement with respect to themselves), severally, upon
     demand for all out-of-pocket expenses that shall have been reasonably
     incurred by the Representatives and the Underwriters in connection with the
     proposed purchase and the offering and sale of the Shares, including but
     not limited to fees and disbursements of counsel, printing expenses, travel
     expenses, postage, facsimile and telephone charges.

7.          Effectiveness of this Agreement.

     (a)           This Agreement shall not become effective until the later of
            (i) the execution of this Agreement by the parties hereto and (ii)
            if required, notification by the Commission to the Company and the
            Representatives of the effectiveness of the Registration Statement
            under the Securities Act.

                                       23



     (b)           Prior to such effectiveness, this Agreement may be terminated
            by any party by notice to each of the other parties hereto, and any
            such termination shall be without liability on the part of (i) the
            Company to any Underwriter, except that the Company shall be
            obligated to reimburse the expenses of the Representatives and the
            Underwriters pursuant to Sections 4 and 6 hereof, (ii) any
            Underwriter to the Company or (iii) any party hereto to any other
            party, except that the provisions of Section 8 shall at all times be
            effective and shall survive such termination.

8.          Indemnification.

     (a)           The Company will indemnify and hold harmless each
            Underwriter, the directors, officers, employees and agents of each
            Underwriter and each person, if any, who controls each Underwriter
            within the meaning of Section 15 of the Act or Section 20 of the
            Exchange Act from and against any and all losses, claims,
            liabilities, expenses and damages (including, but not limited to,
            any and all investigative, legal and other expenses reasonably
            incurred in connection with, and any and all amounts paid in
            settlement of, any action, suit or proceeding between any of the
            indemnified parties and any indemnifying parties or between any
            indemnified party and any third party, or otherwise, or any claim
            asserted), as and when incurred, to which any Underwriter, or any
            such person, may become subject under the Act, the Exchange Act or
            other federal or state statutory law or regulation, at common law or
            otherwise, insofar as such losses, claims, liabilities, expenses or
            damages arise out of or are based on (i) any untrue statement or
            alleged untrue statement of a material fact contained in any
            preliminary prospectus, the Registration Statement or the Prospectus
            or any amendment or supplement to the Registration Statement or the
            Prospectus or in any documents filed under the Exchange Act and
            deemed to be incorporated by reference into the Prospectus, or in
            any application or other document executed by or on behalf of the
            Company or based on written information furnished by or on behalf of
            the Company filed in any jurisdiction in order to qualify the Shares
            under the securities laws thereof or filed with the Commission, (ii)
            the omission or alleged omission to state in such document a
            material fact required to be stated in it or necessary to make the
            statements in it not misleading or (iii) any act or failure to act
            or any alleged act or failure to act by any Underwriter in
            connection with, or relating in any manner to, the Shares or the
            offering contemplated hereby, and which is included as part of or
            referred to in any loss, claim, liability, expense or damage arising
            out of or based upon matters covered by clause (i) or (ii) above
            (provided that the Company shall not be liable under this clause
            (iii) to the extent it is finally judicially determined by a court
            of competent jurisdiction that such loss, claim, liability, expense
            or damage resulted directly from any such acts or failures to act
            undertaken or omitted to be taken by such Underwriter through its
            gross negligence or willful misconduct); provided that the Company
            will not be liable to the extent that such loss, claim, liability,
            expense or damage arises from the sale of the Shares in the public
            offering to any person by an Underwriter and is based on an untrue
            statement or omission or alleged untrue statement or omission made
            in reliance on and in conformity with information relating to either

                                       24



            Underwriter furnished in writing to the Company by such Underwriter
            expressly for inclusion in the Registration Statement, any
            preliminary prospectus or the Prospectus. This indemnity agreement
            will be in addition to any liability that the Company might
            otherwise have.

     (b)           Each Underwriter agrees, severally and not jointly, to
            indemnify and hold harmless the Company, each person, if any, who
            controls the Company within the meaning of Section 15 of the Act or
            Section 20 of the Exchange Act, each director of the Company and
            each officer of the Company who signs the Registration Statement to
            the same extent as the foregoing indemnity from the Company to each
            Underwriter, but only insofar as losses, claims, liabilities,
            expenses or damages arise out of or are based on any untrue
            statement or omission or alleged untrue statement or omission made
            in reliance on and in conformity with written information relating
            to such Underwriter furnished in writing to the Company by the
            Representatives expressly for use in the Registration Statement or
            the Prospectus. This indemnity agreement will be in addition to any
            liability that each Underwriter may otherwise have; provided,
            however, that in no case will any Underwriter be liable or
            responsible for any amount in excess of the underwriting discounts
            and commissions received by such Underwriter.

     (c)           Any party that proposes to assert the right to be indemnified
            under this Section 8 will, promptly after receipt of notice of
            commencement of any action against such party in respect of which a
            claim is to be made against an indemnifying party or parties under
            this Section 8, notify each such indemnifying party of the
            commencement of such action, enclosing a copy of all papers served,
            but the omission so to notify such indemnifying party will not
            relieve it from any liability that it may have to any indemnified
            party under the foregoing provisions of this Section 8 unless, and
            only to the extent that, such omission results in the forfeiture of
            substantive rights or defenses by the indemnifying party. If any
            such action is brought against any indemnified party and it notifies
            the indemnifying party of its commencement, the indemnifying party
            will be entitled to participate in and, to the extent that it elects
            by delivering written notice to the indemnified party promptly after
            receiving notice of the commencement of the action from the
            indemnified party to assume the defense of the action, with counsel
            satisfactory to the indemnified party, and after notice from the
            indemnifying party to the indemnified party of its election to
            assume the defense, the indemnifying party will not be liable to the
            indemnified party for any legal or other expenses except as provided
            below and except for the reasonable costs of investigation
            subsequently incurred by the indemnified party in connection with
            the defense. The indemnified party will have the right to employ its
            own counsel in any such action, but the fees, expenses and other
            charges of such counsel will be at the expense of such indemnified
            party unless (i) the employment of counsel by the indemnified party
            has been authorized in writing by the indemnifying party, (ii) the
            indemnified party has reasonably concluded (based on advice of
            counsel) that there may be legal defenses available to it or other
            indemnified parties that are different from or in addition to those
            available to the indemnifying party, (iii) a

                                       25



            conflict or potential conflict exists (based on advice of counsel to
            the indemnified party) between the indemnified party and the
            indemnifying party (in which case the indemnifying party will not
            have the right to direct the defense of such action on behalf of the
            indemnified party) or (iv) the indemnifying party has not in fact
            employed counsel to assume the defense of such action within a
            reasonable time after receiving notice of the commencement of the
            action, in each of which cases the reasonable fees, disbursements
            and other charges of counsel will be at the expense of the
            indemnifying party or parties. It is understood that the
            indemnifying party shall not, in connection with any proceeding or
            related proceedings in the same jurisdiction, be liable for the
            reasonable fees, disbursements and other charges of more than one
            separate firm admitted to practice in such jurisdiction at any one
            time for all such indemnified party or parties. All such fees,
            disbursements and other charges will be reimbursed by the
            indemnifying party promptly as they are incurred. An indemnifying
            party will not be liable for any settlement of any action or claim
            effected without its written consent (which consent will not be
            unreasonably withheld). No indemnifying party shall, without the
            prior written consent of each indemnified party, settle or
            compromise or consent to the entry of any judgment in any pending or
            threatened claim, action or proceeding relating to the matters
            contemplated by this Section 8 (whether or not any indemnified party
            is a party thereto), unless such settlement, compromise or consent
            includes an unconditional release of each indemnified party from all
            liability arising or that may arise out of such claim, action or
            proceeding. Notwithstanding any other provision of this Section
            8(c), if at any time an indemnified party shall have requested an
            indemnifying party to reimburse the indemnified party for fees and
            expenses of counsel, such indemnifying party agrees that it shall be
            liable for any settlement effected without its written consent if
            (1) such settlement is entered into more than 45 days after receipt
            by such indemnifying party of the aforesaid request, (2) such
            indemnifying party shall have received notice of the terms of such
            settlement at least 30 days prior to such settlement being entered
            into and (3) such indemnifying party shall not have reimbursed such
            indemnified party in accordance with such request prior to the date
            of such settlement.

     (d)           In order to provide for just and equitable contribution in
            circumstances in which the indemnification provided for in the
            foregoing paragraphs of this Section 8 is applicable in accordance
            with its terms but for any reason is held to be unavailable from the
            Company or the Underwriters, the Company and the Underwriters shall
            contribute to the total losses, claims, liabilities, expenses and
            damages (including any investigative, legal and other expenses
            reasonably incurred in connection with, and any amount paid in
            settlement of, any action, suit or proceeding or any claim asserted,
            but after deducting any contribution received by the Company from
            persons other than the Underwriters, such as persons who control the
            Company within the meaning of the Act, officers of the Company who
            signed the Registration Statement and directors of the Company, who
            also may be liable for contribution) to which the Company and the
            Underwriters may be

                                       26



            subject in such proportion as shall be appropriate to reflect the
            relative benefits received by the Company on the one hand and the
            Underwriters on the other. The relative benefits received by the
            Company on the one hand and the Underwriters on the other shall be
            deemed to be in the same proportion as the total net proceeds from
            the offering (before deducting expenses) received by the Company
            bear to the total underwriting discounts and commissions received by
            the Underwriters, in each case as set forth in the table on the
            cover page of the Prospectus. If, but only if, the allocation
            provided by the foregoing sentence is not permitted by applicable
            law, the allocation of contribution shall be made in such proportion
            as is appropriate to reflect not only the relative benefits referred
            to in the foregoing sentence but also the relative fault of the
            Company, on the one hand, and the Underwriters, on the other, with
            respect to the statements or omissions that resulted in such loss,
            claim, liability, expense or damage, or action in respect thereof,
            as well as any other relevant equitable considerations with respect
            to such offering. Such relative fault shall be determined by
            reference to whether the untrue or alleged untrue statement of a
            material fact or the omission or alleged omission to state a
            material fact related to information supplied by the Company or the
            Underwriters, the intent of the parties and their relative
            knowledge, access to information and opportunity to correct or
            prevent such statement or omission. The Company and the Underwriters
            agree that it would not be just and equitable if contributions
            pursuant to this Section 8(d) were to be determined by pro rata
            allocation or by any other method of allocation which does not take
            into account the equitable considerations referred to herein. The
            amount paid or payable by an indemnified party as a result of the
            loss, claim, liability, expense or damage, or action in respect
            thereof, referred to above in this Section 8(d) shall be deemed to
            include, for purpose of this Section 8(d), any legal or other
            expenses reasonably incurred by such indemnified party in connection
            with investigating or defending any such action or claim.
            Notwithstanding the provisions of this Section 8(d), no Underwriter
            shall be required to contribute any amount in excess of the
            underwriting discounts and commissions received by it and no person
            found guilty of fraudulent misrepresentation (within the meaning of
            Section 11(f) of the Act) will be entitled to contribution from any
            person who was not guilty of such fraudulent misrepresentation. The
            Underwriters' obligations to contribute as provided in this Section
            8(d) are several to their respective underwriting obligations and
            not joint. For purposes of this Section 8(d), any person who
            controls a party to this Agreement within the meaning of the Act
            will have the same rights to contribution as that party, and each
            officer of the Company who signed the Registration Statement will
            have the same rights to contribution as the Company, subject in each
            case to the provisions hereof. Any party entitled to contribution,
            promptly after receipt of notice of commencement of any action
            against such party in respect of which a claim for contribution may
            be made under this Section 8(d), will notify any such party or
            parties from whom contribution may be sought, but the omission so to
            notify will not relieve the party or parties from whom contribution
            may be sought from any other obligation it or they may have under
            this Section 8(d). Except for a settlement entered into pursuant to
            the

                                       27



            last sentence of Section 8(c) hereof, no party will be liable for
            contribution with respect to any action or claim settled without its
            written consent (which consent will not be unreasonably withheld).

     (e)           The indemnity and contribution agreements contained in this
            Section 8 and the representations and warranties of the Company
            contained in this Agreement shall remain operative and in full force
            and effect regardless of (i) any investigation made by or on behalf
            of the Underwriters, (ii) acceptance of the Shares and payment
            therefor or (iii) any termination of this Agreement.

9.          Termination. The obligations of the Underwriters under this
     Agreement may be terminated at any time on or prior to the Closing Date
     (or, with respect to the Option Shares, on or prior to the Option Closing
     Date), by notice to the Company from the Representatives if, prior to
     delivery and payment for the Shares (or the Option Shares, as the case may
     be), in the sole judgment of the Representatives, (a) there has been, since
     the respective dates as of which information is given in the Registration
     Statement and the Prospectus, any material adverse change or any
     development involving a prospective change, which has had or is reasonably
     likely to have a Material Adverse Effect; (b) trading in any of the equity
     securities of the Company shall have been suspended by the Commission, the
     NASD or the New York Stock Exchange; (c) trading in securities generally on
     the New York Stock Exchange or the Nasdaq National Market shall have been
     suspended or limited or minimum or maximum prices shall have been generally
     established on such exchange or automated quotation system, or additional
     material governmental restrictions, not in force on the date of this
     Agreement, shall have been imposed upon trading in securities generally by
     the New York Stock Exchange or The Nasdaq Stock Market or by order of the
     Commission or the NASD or any court or other governmental authority; (d) a
     general banking moratorium shall have been declared by federal or New York
     or Oklahoma State authorities; (e) there shall have occurred any outbreak
     or escalation of national or international hostilities or any crisis or
     calamity, or any change in the United States or international financial or
     securities markets, or any substantial change or development involving a
     prospective substantial change in national or international political,
     financial or economic conditions, as in the judgment of the Representatives
     is material and adverse and makes it impractical or inadvisable to market
     the Shares in the manner and on the terms described in the Prospectus or to
     enforce contracts for the sale of securities; (f) any downgrading, or
     placement on any watch list for possible downgrading, in the rating of the
     Company's debt securities by any "nationally recognized statistical rating
     organization" (as defined for purposes of Rule 436(g) under the Exchange
     Act); (g) the taking of any action by any governmental body or agency in
     respect of its monetary or fiscal affairs that in the judgment of the
     Representatives has a material adverse effect on the securities markets in
     the United States; or (h) the Company shall have sustained a loss by
     strike, fire, flood, earthquake, accident or other calamity of such
     character as in the judgment of the Representatives may interfere
     materially with the business and operations of the Company regardless of
     whether of not such loss shall have been insured. Any termination pursuant
     to this Section 9 shall be without liability on the part of (i) the Company
     to any Underwriter, except that the Company shall be obligated to reimburse
     the expenses of the

                                       28



     Representatives and the Underwriters pursuant to Section 4 and 6 hereof,
     (ii) any Underwriter to the Company or (iii) of any party hereto to any
     other party except that the provisions of Section 8 shall at all times be
     effective and shall survive such termination.

10.         Default of One or More of the Several Underwriters.

     (a)           If, on the Closing Date or the Option Closing Date, as the
            case may be, any one or more of the several Underwriters shall fail
            or refuse to purchase Shares that it or they have agreed to purchase
            hereunder on such date, and the aggregate number of Shares that such
            defaulting Underwriter or Underwriters agreed but failed or refused
            to purchase does not exceed 10% of the aggregate number of the
            Shares to be purchased on such date, the other Underwriters shall be
            obligated, severally, in the proportions that the number of Firm
            Shares set forth opposite their respective names on Schedule I
            hereto bears to the aggregate number of Firm Shares set forth
            opposite the names of all such non-defaulting Underwriters, or in
            such other proportions as may be specified by the Representatives
            with the consent of the non-defaulting Underwriters, to purchase the
            Shares that such defaulting Underwriter or Underwriters agreed but
            failed or refused to purchase on such date. If, on the Closing Date
            or the Option Closing Date, as the case may be, any one or more of
            the Underwriters shall fail or refuse to purchase Shares and the
            aggregate number of Shares with respect to which such default occurs
            exceeds 10% of the aggregate number of Shares to be purchased on
            such date, and arrangements satisfactory to the Representatives and
            the Company for the purchase of such Shares are not made within 48
            hours after such default, this Agreement shall terminate without
            liability on the part of any non-defaulting Underwriters or the
            Company for the purchase or sale of any Shares under this Agreement.
            In any such case, either the Representatives or the Company shall
            have the right to postpone the Closing Date or the Option Closing
            Date, as the case may be, but in no event for a period longer than
            seven days, in order that the required changes, if any, to the
            Registration Statement and the Prospectus or in any other documents
            or arrangements may be effected.

     (b)           As used in this Section 10, the term "Underwriter" shall be
            deemed to include any person substituted for a defaulting
            Underwriter under this Section 10. Any action taken pursuant to this
            Section 10 shall not relieve any defaulting Underwriter from
            liability in respect of any default of such Underwriter under this
            Agreement.

11.         Miscellaneous.

     (a)           Notice given pursuant to any of the provisions of this
            Agreement shall be in writing and, unless otherwise specified, shall
            be mailed, hand delivered or telecopied and confirmed (i) if to the
            Company, at the office of the Company, 100 West Fifth Street, Tulsa,
            Oklahoma 74103, Facsimile: 918-588-7971, Attention: Chief Financial

            of America Securities LLC, 9 West 57th Street, New York, New York

            Facsimile: 212-583-8567, Attention: Nicholas T. Ganz, (B) UBS

            212-821-4042, Attention: General Counsel, and (C) J.P. Morgan
            Securities Inc., 277 Park Avenue, New York, New York 10172,
            Facsimile: 212-622-6037, Attention: Paul A. O'Hern. Any such notice
            shall be effective only upon receipt. Any notice under Section 9 may
            be made by telecopy or telephone, but if so made shall be
            subsequently confirmed in writing.

     (b)           This Agreement has been and is made solely for the benefit of
            the several Underwriters and the Company and of the controlling
            persons, directors and officers referred to in Section 8, and their
            respective successors and assigns, and no other person shall acquire
            or have any right under or by virtue of this Agreement. The term
            "successors and assigns" as used in this Agreement shall not include
            a purchaser, as such purchaser, of Shares from the Underwriters.

     (c)           All representations, warranties and agreements of the Company
            contained herein or in certificates or other instruments delivered
            pursuant hereto, shall remain operative and in full force and effect
            regardless of any investigation made by or on behalf of the
            Underwriters or any of its controlling persons and shall survive
            delivery of and payment for the Shares hereunder.

     (d)           Any action required or permitted to be taken by the
            Representatives under this Agreement shall be taken by them jointly.

     (e)           THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
            ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     (f)           Except as set forth below, no claim may be commenced,
            prosecuted or continued in any court other than the courts of the
            State of New York located in the City and County of New York or in
            the United States District Court for the Southern District of New
            York, which courts shall have jurisdiction of such courts and
            personal service with respect thereto. The Company hereby consents
            to personal jurisdiction, service and venue in any court in which
            any claim arising out of or in any way relating to this Agreement is
            brought by any third party against any indemnified party. Each of
            the Representatives and the Company (on its behalf and, to the
            extent permitted by applicable law, on behalf of all indemnified
            parties and its and their stockholders and affiliates) waives all
            right to trial by jury in any action, proceeding or counterclaim
            (whether based upon contract, tort or otherwise) in any way arising
            out of or relating to this Agreement. The Company agrees that a
            final judgment in any such action, proceeding or counterclaim
            brought in any such court shall be conclusive and binding upon the
            Company and may be enforced in any other courts in the jurisdiction
            of which the Company is or may be subject, by suit upon such
            judgment.

                                       30



     (g)           This Agreement may be signed in two or more counterparts with
            the same effect as if the signatures thereto and hereto were upon
            the same instrument.

     (h)           In case any provision in this Agreement shall be invalid,
            illegal or unenforceable, the validity, legality and enforceability
            of the remaining provisions shall not in any way be affected or
            impaired thereby.

     (i)           The Company and the Underwriters each hereby irrevocably
            waive any right they may have to a trial by jury in respect of any
            claim based upon or arising out of this Agreement or the
            transactions contemplated hereby.

     (j)           This Agreement may not be amended or otherwise modified or
            any provision hereof waived except by an instrument in writing
            signed by the Representatives and the Company.

     Please confirm that the foregoing correctly sets forth the agreement
between the Company and the several Underwriters.

                                                                       EXHIBIT B

                               Form of Opinion of
                             Counsel to the Company

     1.   The Company and each of its significant subsidiaries (as defined in
Rule 1-02(w) of Regulation S-X of the Rules and Regulations) is a corporation,
limited liability company, general partnership or limited partnership duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation or organization and has full power and
authority to conduct all the activities conducted by it, to own or lease all the
assets owned or leased by it and to conduct its business as described in the
Registration Statement and the Prospectus, except in each case as would not,
individually or in the aggregate, result in a Material Adverse Effect. The
Company is the direct or indirect sole record owner and, to such counsel's
knowledge, the sole beneficial owner of all of the capital stock, capital
interests or partnership interests of each of its Subsidiaries, except as
otherwise set forth on Schedule II to the Underwriting Agreement, dated as of
January 23, 2003 (together with the Price Determination Agreement included
therein as Exhibit A, the "Agreement").

     2.   All of the shares of Common Stock have been, and the Shares, when
delivered and paid for in accordance with the provisions of the Agreement, will
be, duly authorized, validly issued, fully paid and nonassessable and will not
be subject to (a) any preemptive right arising under the certificate of
incorporation, by-laws or other organizational document of the Company or such
significant subsidiary or the laws of the State of Oklahoma, (b) co-sale right,
(c) right of first refusal or (d) other similar right. Except as described in
the Registration Statement or the Prospectus or in the documents incorporated
therein by reference or in any employee or director compensation arrangements
pursuant to a plan in effect on the date of this opinion, to such counsel's
knowledge, there is no commitment or arrangement to issue, and there are no
outstanding options, warrants or other rights calling for the issuance of, any
share of capital stock of the Company or any Subsidiary to any person or any
security or other instrument that by its terms is convertible into, exercisable
for or exchangeable for capital stock of the Company.

     3.   No consent, approval, authorization or order of, or any filing or
declaration with, any court or governmental agency or body is required in
connection with (a) the authorization, issuance, transfer, sale or delivery of
the Shares by the Company, (b) the execution, delivery and performance of the
Agreement, by the Company or (c) the taking by the Company of any action
contemplated thereby except such as (1) have been obtained under the Act and the
Rules and Regulations and (2) may be required under state securities or "Blue
Sky" laws or by the by-laws and rules of the NASD in connection with the
purchase and distribution by the Underwriters of the Shares to be sold by the
Company.

     4.   The authorized, issued and outstanding capital stock of the Company is
as set forth in the Registration Statement and the Prospectus. The form of
certificate used to evidence the Common Stock and filed as an Exhibit to the
Registration Statement is in due and proper form and complies with all
applicable statutory requirements.

                                       B-1



     5.   All issued and outstanding shares of capital stock or other equity
interests of each significant subsidiary (as defined in Rule 1-02(w) of
Regulation S-X of the Rules and Regulations) of the Company have been duly
authorized and validly issued and, to such counsel's knowledge, have not been
issued in violation of or subject to (a) any preemptive right arising under the
certificate of incorporation, by-laws or other organizational document of the
Company or such significant subsidiary or the laws of the State of Oklahoma or
any such significant subsidiary's jurisdiction of incorporation or organization,
(b) co-sale right, (c) right of first refusal or (d) other similar right. To
such counsel's knowledge, all of the shares of capital stock or other equity
interests in the Subsidiaries reflected as owned by the Company on Schedule II
to the Agreement are owned by the Company free and clear of any security
interests, liens, encumbrances and claims whatsoever.

     6.   The Registration Statement and the Prospectus (including any documents
incorporated by reference into the Prospectus, at the time they were filed)
comply or complied in all material respects as to form with the requirements of
the Act, the Rules and Regulations, the Exchange Act and the Exchange Act Rules
and Regulations (except that such counsel need not express an opinion as to
financial statements, schedules and other financial data contained in the
Registration Statement or the Prospectus or incorporated by reference therein).

     7.   The information in the Registration Statement and the Prospectus under
the captions "Transactions with Westar" and "Description of Capital Stock,"
insofar as such statements purport to summarize the legal matters or documents
referred to therein, present fair summaries of such legal matters and documents.

     8.   To such counsel's knowledge, (a) any instrument, document, lease,
license, contract or other agreement (collectively, "Documents") required to be
described or referred to in the Registration Statement or the Prospectus has
been properly described or referred to therein, and (b) any Document required to
be filed as an exhibit to the Registration Statement has been filed as an
exhibit thereto or has been incorporated as an exhibit by reference in the
Registration Statement; and, to such counsel's knowledge, no default exists in
the due performance or observance of any obligation, agreement, covenant or
condition contained in any Document filed or required to be filed as an exhibit
to the Registration Statement.

     9.   To such counsel's knowledge, no person or entity has the right to
require the registration under the Act of shares of Common Stock or other
securities of the Company by reason of the filing or effectiveness of the
Registration Statement.

     10.  To such counsel's knowledge, the Company is not in violation of, or in
default with respect to, any law, rule, regulation, order, judgment or decree,
except as may be described in the Registration Statement and the Prospectus
(including the documents incorporated by reference therein) or such as in the
aggregate do not now have and would not reasonably be expected to have a
Material Adverse Effect.

                                       B-2



     11.   All descriptions in the Prospectus of statutes, regulations or legal
or governmental proceedings are accurate and fairly present the information
required to be shown in all material respects.

     12.  The Company has full corporate power and authority to enter into the
Agreement and the Transaction Agreement, and the Agreement and the Transaction
Agreement have been duly authorized, executed and delivered by the Company, are
legal, valid and binding obligations of the Company, enforceable against the
Company in accordance with their respective terms, subject to the effect of
bankruptcy, insolvency, reorganization, receivership, moratorium and other laws
affecting the rights and remedies of creditors generally and general equitable
principles and subject to any principles of public policy limiting the rights to
enforce any indemnification provisions contained therein.

     13.  The execution and delivery by the Company of, and the performance by
the Company of its agreements in, the Agreement and the Transaction Agreement do
not and will not (a) violate the certificate of incorporation or by-laws of the
Company, (b) breach or result in a default under, cause the time for performance
of any obligation to be accelerated under, or result in the creation or
imposition of any lien, charge or encumbrance upon any of the assets of the
Company or any of its Subsidiaries pursuant to the terms of, any indenture,
mortgage, deed of trust, loan agreement, bond, debenture, note agreement,
capital lease or other evidence of indebtedness of which such counsel has
knowledge, (c) breach or result in a default under, cause the time for
performance of any obligation to be accelerated under, or result in the creation
or imposition of any lien, charge or encumbrance upon any of the assets of the
Company or any of its assets pursuant to the terms of, any (i) voting trust
arrangement or any contract or other agreement to which the Company is a party
that restricts the ability of the Company to issue securities of which such
counsel has knowledge or (ii) Document filed as an exhibit to, or incorporated
as an exhibit by reference in, the Registration Statement, (d) breach or
otherwise violate any existing obligation of the Company under any court or
administrative order, judgment or decree of which such counsel has knowledge or
(e) violate applicable provisions of any statute or regulation in the State of
Oklahoma or of the United States; except with respect to items (b), (c) and (d)
above, such conflicts, agreements, breaches, violations or defaults as would not
have a Material Adverse Effect.

     14.  Delivery of certificates for the Shares will transfer valid and
marketable title thereto to each Underwriter that has purchased such Shares in
good faith and without notice of any adverse claim with respect thereto.

     15.  The Company is not an "investment company" or an "affiliated person"
of, or "promoter" or "principal underwriter" for, an "investment company," as
such terms are defined in the Investment Company Act of 1940, as amended.

     Such counsel hereby confirms to the Underwriters that such counsel has been
orally advised by the Commission that the Registration Statement has become
effective under the Act and that, to such counsel's knowledge, no order
suspending the effectiveness of the Registration Statement has been issued and
no proceeding for that purpose has been instituted or is threatened, pending or
contemplated.

     Such counsel hereby further confirms to the Underwriters that, to such
counsel's knowledge, there are no actions, suits, proceedings or investigations
pending or overtly threatened in writing against the Company or any of its
Subsidiaries, or any of their respective officers or directors in their
capacities as such, before or by any court, governmental agency or arbitrator
that (i) seek to challenge the legality or enforceability of the Agreement or
the Shares, (ii) except as set forth in the Registration Statement or Prospectus
or any documents incorporated by reference therein, seek to challenge the
legality or enforceability of any of the Documents filed, or required to be
filed, as exhibits to the Registration Statement, (iii) except as set forth in
the Registration Statement or Prospectus or any documents incorporated by
reference therein seek damages or other remedies with respect to any of the
Documents filed, or required to be filed, as exhibits to the Registration
Statement except as would not have a Material Adverse Effect, (iv) except as set
forth in or contemplated by the Registration Statement or the Prospectus or any
of the documents incorporated by reference into the Registration Statement or
the Prospectus, seek money damages in excess of 10% of the current assets of the
Company and its subsidiaries on a consolidated basis or seek to impose criminal
penalties upon the Company, any of its Subsidiaries or any of their respective
officers or directors in their capacities as such and of which such counsel has
knowledge, other than ordinary routine litigation incidental to the Company's
business, or (v) except as set forth in or contemplated by the Registration
Statement or the Prospectus or any of the documents incorporated by reference
into the Registration Statement or the Prospectus, seek to enjoin any of the
business activities of the Company or any of its Subsidiaries or the
transactions described in the Prospectus and of which such counsel has
knowledge.

     Such counsel has participated in the preparation of the Registration
Statement and the Prospectus. From time to time in connection therewith such
counsel has had discussions with (i) officers and representatives of the
Company, (ii) representatives of KPMG LLP, the independent accountants who
examined certain of the financial statements of the Company and its consolidated
subsidiaries included or incorporated by reference in the Registration Statement
and the Prospectus, and (iii) the Underwriters' representatives and counsel
concerning the information contained in or incorporated by reference in the
Registration Statement and the Prospectus. Such counsel has not independently
verified and is not passing upon, and does not assume any responsibility for,
the accuracy, completeness or fairness of the information contained in or
incorporated by reference in the Registration Statement and the Prospectus
except to the extent set forth in paragraphs 4 and 7 above. Based solely upon
the participation and discussions described above, however, no facts have come
to such counsel's attention that cause such counsel to believe that the
Registration Statement and the Prospectus, when read collectively (except for
the following as to which such counsel is not called upon to express a view: (a)
financial statements, schedules and other financial data contained in the
Registration Statement or the Prospectus (or incorporated by reference therein)
and (b) the information

                                       B-4



referred to under the caption "Experts" as having been included or incorporated
by reference into the Registration Statement and the Prospectus on the authority
of KPMG LLP as experts), as of the date thereof or as of the date hereof,
contained or contains any untrue statement of a material fact or omitted or
omits to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances in which
they were made, not misleading.

     In rendering the foregoing opinion, counsel may rely, to the extent they
deem such reliance proper, on the opinions of other counsel to the Company as to
matters governed by the laws of jurisdictions other than the United States and
the State of Oklahoma, and as to matters of fact, upon certificates of officers
of the Company and of government officials; provided that such counsel shall
state that in such counsel's opinion that such counsel and the Underwriters are
justified in relying on such opinions of other counsel. Copies of all such
opinions and certificates shall be furnished to counsel to the Underwriters on
the Closing Date. For purposes of paragraph 3 and 13(e) above, such counsel has
reviewed only those statutes, rules and regulations, including regulatory rules
and regulations, that in such counsel's experience are applicable to
transactions of the type contemplated by the Agreement or the Indenture or for
the offering, issuance, sale or delivery of the Shares. For purposes of the
foregoing opinion, the term "knowledge" shall mean the conscious awareness of
information by any Primary Lawyer, without undertaking any investigation. The
term "Primary Lawyer" shall mean each lawyer in such counsel's Firm who gave
substantive attention to representations of the Company in connection with the
transaction described in the Prospectus.

     Capitalized terms used in such opinion but not defined shall have the
meanings assigned to them in the Agreement, except the term "Subsidiaries" shall
not include any subsidiaries listed on Schedule II to the Agreement as being
organized under the laws of Mexico ("Excluded Subsidiaries") and counsel shall
not be required to express any opinions regarding any Excluded Subsidiaries.
