the purposes set forth in Section 1(b). The Initial Units, the Treasury Units
(as hereinafter defined) and the Option Units are hereinafter collectively
referred to as the "Units."

     Each Corporate Unit will consist of (a) a stock purchase contract (a
"Purchase Contract") for the purchase of 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.,

or about January 28, 2003, in each case, with the material terms described in
the Prospectus (as hereinafter defined)). Holders of Corporate Units will be

2.5% undivided beneficial interest in zero-coupon U.S. Treasury securities
(CUSIP No. 912803AJ2), each in a principal amount equal to $1,000, payable on
February 15, 2006 (a "Treasury Security"). Under each Purchase Contract,
pursuant to the terms of a Purchase Contract Agreement, to be dated as of

     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 unit for the Units and the purchase
price per unit for the Units 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 Units 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 unit for the
          Initial Units to be agreed upon by the Underwriters and the Company in
          accordance with Section 1(d) or 1(e) hereof and set forth in the Price
          Determination Agreement, the number of the Initial Units set forth
          opposite the name of such Underwriter in Schedule I, plus such
          additional number of Initial Units 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 2,100,000 Option Units from the Company at the
          same price per share as the Underwriters will pay for the Initial
          Units. The Option may be exercised only to cover over-allotments in
          the sale of the Initial Units by the Underwriters and may be exercised
          in whole or in part at any time (but not more than once) on or before
          the 13th day after the date of this Agreement (or, if the Company has
          elected to rely on Rule 430A, on or before the 13th day after the date
          of the Price Determination Agreement), upon written or telegraphic
          notice (the "Option Units

                                        3



          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 Unit Notice
          (the "Option Closing Date") setting forth the aggregate number of
          Option Units 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 Units set forth in the Option Units
          Notice and each Underwriter will purchase such percentage of the
          Option Units as is equal to the percentage of Initial Units that such
          Underwriter is purchasing, as adjusted as the Representatives deem
          advisable to avoid fractional shares.

     (c)        The Senior Notes or the Applicable Ownership Interest in the
          Treasury Portfolio, as the case may be, and Treasury Securities
          constituting a part of the Corporate Units and Treasury Units,
          respectively, will be pledged to the Collateral Agent to secure
          holders' obligations to purchase Common Stock under the Purchase
          Contracts. Such pledge shall be effected by: (i) the delivery to the
          Collateral Agent of the Senior Notes to be pledged in certificated
          form endorsed in blank and (ii) the transfer to the Collateral Agent
          of the Treasury Securities to be pledged, in each case in accordance
          with the Pledge Agreement.

     (d)        If the Company has elected not to rely on Rule 430A of the Rules
          and Regulations, the initial public offering price per unit for the
          Initial Units and the purchase price per unit for the Initial Units 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 unit price information shall
          be filed before the Registration Statement becomes effective.

     (e)        If the Company has elected to rely on Rule 430A of the Rules and
          Regulations, the initial public offering price per unit for the
          Initial Units and the purchase price per unit for the Initial Units 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 Initial Units shall be made to the
          Representatives for the accounts of the Underwriters against payment

          Collateral Agent of the Senior Notes constituting a part of the
          Corporate Units by the Company to the Representatives. Such payment
          shall be made at 10:00 a.m., New York City time, on the third business

          Initial Units 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 Initial Units shall be made through the
          facilities of The Depository Trust Company unless the Representatives
          shall otherwise instruct.

                                        4



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

          Corporate Units, the Company 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 Initial Units and Option Units
          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 Units 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

          Underwriter of the Initial Units and Option Units.

     (b)        The Company has not received, and has no notice of, any order of

          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

          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

          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 Units 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

          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, the Exchange Act
          and the Trust Indenture Act, as applicable, the Rules and Regulations,
          the Exchange Act Rules and Regulations and the Trust Indenture Act
          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

          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 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 Corporate Units, including the Senior Notes, have been duly
          authorized, executed and delivered by the Company; the Corporate
          Units, when issued against payment therefor as contemplated by this
          Agreement, will be entitled to the benefits of the Purchase Contract
          Agreement; the Senior Notes, when authenticated by the Trustee and
          issued against payment therefor as contemplated by this Agreement,
          will be entitled to the benefits of the Indenture; and the Corporate
          Units and the Senior Notes (when so issued) are legal, valid and
          binding obligations of the Company, enforceable against the Company in

                                        8



          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; provided, however, that upon the
          occurrence of a Termination Event (as defined in the Purchase Contract
          Agreement), the Bankruptcy Code (11 U.S.C. (SS) 101-1330, as amended)
          should not substantively limit the provisions of Sections 3.15 and
          5.06 of the Purchase Contract Agreement or Section 4.04 of the Pledge
          Agreement that require termination of the Purchase Contracts and
          release of the Collateral Agent's security interest in (a) the Senior
          Notes, (b) the Treasury Securities or (c) the applicable ownership
          interest of the Treasury Portfolio, as applicable, and the transfer of
          such securities to the Purchase Contract Agent, for benefit of the
          holders of the Units; provided further, however, the Company makes no
          representation as to whether a court exercising bankruptcy
          jurisdiction might issue a temporary restraining order or provide
          other interim relief that would delay the exercise of such termination
          right for a period of time pending final adjudication of any challenge
          to the exercise of such right during a bankruptcy case involving the
          Company.

     (g)        The outstanding shares of Common Stock have been duly
          authorized, validly issued, fully paid and nonassessable and will not
          be subject to any preemptive or similar right. The shares of Common
          Stock issuable pursuant to the Purchase Contracts have been duly
          authorized and, when issued and paid for in accordance with the terms
          of the Purchase Contracts, will be validly issued, fully paid and
          nonassessable and will not be subject to any preemptive or similar
          right. The description of the Units in the Registration Statement and
          the Prospectus, including the Purchase Contract Agreement, the
          Purchase Contracts, the Pledge Agreement, the Remarketing Agreement
          and the Senior Notes, 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 obligations.

     (h)        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

                                        9



          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.

     (i)        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.

     (j)        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.

     (k)        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
          Corporate Units, the Company will not be an "investment company"
          within the meaning of the Investment Company Act and will conduct

                                       10



          its business in a manner so that it will not become subject to the
          Investment Company Act.

     (l)        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.

     (m)        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 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.

     (n)        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 Units 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
          Corporate Units and (iii) that the failure to obtain would not result
          in a Material Adverse Effect.

                                       11



     (o)        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, the Transaction Agreement, the
          Purchase Contract Agreement, the Pledge Agreement and the Remarketing
          Agreement. This Agreement, the Transaction Agreement, the Purchase
          Contract Agreement, the Purchase Contracts, the Pledge Agreement, the
          Remarketing Agreement and the Indenture 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; provided, however, that upon
          the occurrence of a Termination Event (as defined in the Purchase
          Contract Agreement), the Bankruptcy Code (11 U.S.C. (SS) 101-1330, as
          amended) should not substantively limit the provisions of Sections
          3.15 and 5.06 of the Purchase Contract Agreement or Section 4.04 of
          the Pledge Agreement that require termination of the Purchase
          Contracts and release of the Collateral Agent's security interest in
          (a) the Senior Notes, (b) the Treasury Securities or (c) the
          applicable ownership interest of the Treasury Portfolio, as
          applicable, and the transfer of such securities to the Purchase
          Contract Agent, for benefit of the holders of the Units; provided
          further, however, the Company makes no representation as to whether a
          court exercising bankruptcy jurisdiction might issue a temporary
          restraining order or provide other interim relief that would delay the
          exercise of such termination right for a period of time pending final
          adjudication of any challenge to the exercise of such right during a
          bankruptcy case involving the Company. The performance of this
          Agreement, the Transaction Agreement, the Purchase Contract Agreement,
          the Purchase Contracts, the Pledge Agreement, the Remarketing
          Agreement, the Indenture and the Corporate Units, including the Senior
          Notes, and the consummation of the transactions contemplated hereby
          and thereby and the application of the net proceeds from the offering
          and sale of the Corporate Units 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, 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.

     (p)        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.

     (q)        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

                                       12



          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; provided, however, that upon the occurrence of a Termination
          Event (as defined in the Purchase Contract Agreement), the Bankruptcy
          Code (11 U.S.C. (SS) 101-1330, as amended) should not substantively
          limit the provisions of Sections 3.15 and 5.06 of the Purchase
          Contract Agreement or Section 4.04 of the Pledge Agreement that
          require termination of the Purchase Contracts and release of the
          Collateral Agent's security interest in (a) the Senior Notes, (b) the
          Treasury Securities or (c) the applicable ownership interest of the
          Treasury Portfolio, as applicable, and the transfer of such securities
          to the Purchase Contract Agent, for benefit of the holders of the
          Units; provided further, however, the Company makes no representation
          as to whether a court exercising bankruptcy jurisdiction might issue a
          temporary restraining order or provide other interim relief that would
          delay the exercise of such termination right for a period of time
          pending final adjudication of any challenge to the exercise of such
          right during a bankruptcy case involving the Company.

     (r)        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 Corporate Units shall be deemed a
          representation and warranty by the Company to the Underwriters as to
          the matters covered thereby.

     (s)        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 Units.

     (t)        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.

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

     (v)        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.

     (w)        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

                                       13



          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.

     (x)        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.

     (y)        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.

     (z)        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) ("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.

     (aa)       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

                                       14



          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.

     (bb)       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.

     (cc)       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.

     (dd)       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 fully in force on the
          Closing Date and the Option Closing Date, as applicable. Neither the
          Company nor any of its subsidiaries has sustained since the date of
          the last financial statements included in the Prospectus any material
          loss or interference with their 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.

     (ee)       With respect to each employee benefit plan, program and
          arrangement (including, without limitation, any "employee benefit
          plan" as defined in Section 3(3) of the Employee Retirement Income
          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,

                                       15



          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) or any
          applicable agreement, in any such case, that could have a Material
          Adverse Effect.

     (ff)       The statements in the Prospectus under the captions "Summary --
          Recent Developments," "Our Company -- Our Business Strategy," "Our
          Company -- Our Business Segments" and "Transactions with Westar" (i)
          are within the coverage of Rule 175(b) under the Act to the extent
          such statements and data constitute forward-looking statements as
          defined in Rule 175(c) and (ii) were made by the Company with a
          reasonable basis and reflect the Company's good faith estimate of the
          matters described therein.

     (gg)       There are no business relationships or related-party
          transactions involving the Company or any of its Subsidiaries or any
          other person required to be described in the Registration Statement or
          the Prospectus that have not been described as required.

     (hh)       There are no outstanding loans (except for immaterial loans
          related to appliance purchases pursuant to a discontinued program
          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
          officers or directors of the Company or any of the members of any of
          them.

     (ii)       Any statistical or market-related data included in the
          Prospectus are based on or derived from sources that the Company
          believes to be reliable and accurate, and the Company has obtained the
          written consent to the use of such data from such sources to the
          extent required.

     (jj)       The Company has not offered, or caused the Underwriters to
          offer, Units to any person with the specific intent to influence
          unlawfully (i) a customer or supplier of the Company or any of its
          Subsidiaries to alter the customer's or supplier's level or type of
          business with the Company or any of its Subsidiaries or (ii) a trade
          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.

     (kk)       There is no broker, finder or other party that is entitled to
          receive from the Company any brokerage or finder's fee or other fee or
          commission as a result of the transactions contemplated by this
          Agreement.

     (ll)       The Company is in substantial compliance with the applicable
          provisions of the Sarbanes-Oxley Act that are effective and is
          actively taking steps to ensure that it will be in compliance with
          other applicable provisions of the Sarbanes-Oxley Act upon the
          effectiveness of such provisions.

                                       16



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 Units
          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 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 Units may be sold, both in
          connection with the offering or sale of the Units and during

                                       17



          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 Units 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 Units by the Underwriters,
          the Company will cooperate with the Representatives and counsel to the
          Underwriters in connection with the registration or qualification of
          the Units 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.

     (g)        During the period of two years commencing on the date of the
          Price Determination Agreement, the Company will furnish to the
          Representatives copies of such financial statements and other periodic
          and special reports as the Company may from time to time distribute
          generally to the holders of any class of its capital stock, and will
          furnish to the Representatives a copy of each annual or other report
          it shall be required to file with the Commission.

     (h)        The Company will make generally available to holders of its
          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
          quarter in which the "effective date of the Registration Statement"
          (as defined in Rule 158 of the Rules and Regulations) falls, an
          earnings statement (which need not be audited but shall be in
          reasonable detail) for a period of 12 months ended commencing after
          such "effective date of the Registration Statement" and satisfying the
          provisions of Section 11(a) of the Act (including Rule 158 of the
          Rules and Regulations).

     (i)        Whether or not the transactions contemplated by this Agreement
          are consummated or this Agreement is terminated, the Company will pay,
          or reimburse if paid by the Underwriters, all costs and expenses
          incident to the performance of the obligations of the Company under
          this Agreement, including but not limited to costs and expenses of or
          relating to (i) the preparation, printing and filing of the
          Registration Statement and exhibits to it, each preliminary
          prospectus, the Prospectus and any amendment or supplement to the
          Registration Statement or the Prospectus, (ii) the preparation and
          delivery of certificates

                                       18



          representing the Units, (iii) the word processing, printing and
          reproduction of this Agreement, the Agreement Among Underwriters, any
          Dealer Agreements and any Underwriter's Questionnaire, (iv) furnishing
          (including costs of shipping, mailing and courier) such copies of the
          Registration Statement, the Prospectus and any preliminary prospectus,
          and all amendments and supplements thereto, as may be requested for
          use in connection with the offering and sale of the Units by the
          Underwriter or by dealers to whom Units may be sold, (v) the listing
          of the Corporate Units on the New York Stock Exchange, (vi) 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 Units for offer and sale under the securities or
          Blue Sky laws of such jurisdictions designated pursuant to Section
          4(f), including the reasonable fees, disbursements and other charges
          of counsel to the Underwriters in connection therewith, and the
          preparation and printing of preliminary, supplemental and final Blue
          Sky memoranda, (viii) counsel to the Company, (ix) the transfer agent
          for the Units and (x) the Accountant.

     (j)        The Company will not at any time, directly or indirectly, take
          any action intended, or that might reasonably be expected, to 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
          Units.

     (k)        The Company will apply the net proceeds from the offering and
          sale of the Units 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 Units 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
          expense, within one business day from the effective date of this
          Agreement, to the Representatives an "electronic Prospectus" to be
          used by the Underwriters in connection with the offering and sale of
          the Units. As used herein, the term "electronic Prospectus" means a
          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 Units 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

                                       19



          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 Units, purchase contracts or shares of Common Stock
          or securities convertible into or exchangeable for any Units, purchase
          contracts or 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

          others within those entities, particularly during the period in which
          such periodic reports are being prepared.

          Representatives, directly or indirectly, publicly issue, sell, offer
          or contract to sell, in the market in which the Units are being
          offered and sold, any securities of the Company or any of its
          subsidiaries which are of the same class as the Units.

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 Units 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

                                       21



          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

          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

          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 Units by the
          Underwriters in accordance with the terms hereof and thereto.

     (c)        Since the respective dates as of which information is given in
          the Registration Statement and the Prospectus, there shall have been

          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

          by the Company at or prior to the Closing Date and, with respect to
          the Option Units, at or prior to the Option Closing Date, shall have
          been duly performed, fulfilled or complied with.

                                       22

     (h)        At the Closing Date and, as to the Option Units, the Option

                date of such certificate, such documents are true and correct in
                all material respects and do not omit to state a material fact

                respect and there has been no

                                       23



                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

                required to be complied with by the Company on or prior to 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 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.

          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.

     (n)        At the Closing Date, (i) the Units shall be rated at least Baa2

          Group, a division of The McGraw-Hill Companies, Inc. ("S&P"),
          respectively, and the Company shall have delivered to the Underwriters
          a letter from each such rating agency, or other evidence satisfactory

          surveillance or review, with possible negative implications, its
          ratings of the Units or any securities of the Company which are of the
          same class as the Units, or of the financial condition of the Company.

          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 Units, at any time prior to the Option

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 Initial Units 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 Corporate Units,

          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.

                                       25



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 Units 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 Units 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
          Units 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 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

                                       26



          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 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,

                                       27



          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 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

                                       28



          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 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 Units 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 Units, on or prior to the Option Closing Date), by
     notice to the Company from the Representatives if, prior to delivery and
     payment for the Units (or the Option Units, as

                                       29



     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 Units 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
     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 Corporate Units that it or they have agreed to
          purchase hereunder on such date, and the aggregate number of Corporate
          Units that such defaulting Underwriter or Underwriters agreed but
          failed or refused to purchase does not exceed 10% of the aggregate
          number of the Corporate Units to be purchased on such date, the other
          Underwriters shall be obligated, severally, in the proportions that
          the number of Initial Units set forth opposite their respective names
          on Schedule I hereto bears to the aggregate number of Initial Units
          set forth opposite the names of all such

                                       30



          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 Units 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 Corporate Units and the aggregate number of
          Corporate Units with respect to which such default occurs exceeds 10%
          of the aggregate number of Corporate Units to be purchased on such
          date, and arrangements satisfactory to the Representatives and the
          Company for the purchase of such Corporate Units 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 Units 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 Officer, or
          (ii) if to the Underwriters, at the offices of (A) UBS Warburg LLC,
          299 Park Avenue, New York, New York 10171, Facsimile: 212-821-4042,

          57th Street, New York, New York 10019, Facsimile: 212-847-5124,
          Attention: Eric Hambleton, 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 Units from the Underwriters.

                                       31



     (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 Units 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.

     (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.

                                       A-3



                                                                       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 issuable pursuant to the Purchase
Contracts have been duly authorized and reserved for issuance and, when issued,
delivered and paid for in accordance with the provisions of the Purchase
Contract Agreement, the Purchase Contracts and the Pledge Agreement, will be
validly issued, fully paid and nonassessable; the issuance of such Common Stock
and the Units 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.   The Units, including the Senior Notes, have been duly authorized,
executed and delivered by the Company; the Units, when issued against payment
therefor as contemplated by the Underwriting Agreement, will be entitled to the
benefits of the Purchase Contract Agreement; the Senior Notes, when issued
against payment therefor as contemplated by the Agreement, will be entitled to
the benefits of the Indenture; and the Units and the Senior Notes (when so
issued) 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.

     4.   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,

                                       B-1



issuance, transfer, sale or delivery of the Units 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 Units to be sold by the Company.

     5.   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.

     6.   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.

     7.   The Registration Statement, the Prospectus (including any documents
incorporated by reference into the Prospectus, at the time they were filed), the
Indenture and the Purchase Contract Agreement comply or complied in all material
respects as to form with the requirements of the Act, the Rules and Regulations,
the Exchange Act, the Exchange Act Rules and Regulations, the Trust Indenture
Act and the Trust Indenture 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).

     8.   The information in the Registration Statement and the Prospectus
under the captions "Transactions with Westar," "Description of the Equity
Units," "Description of the Purchase Contracts," "Certain Provisions of the
Purchase Contract Agreement and the Pledge Agreement," "Description of the
Senior Notes" 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.

     9.   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

                                       B-2



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.

     10.  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.

     11.  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.

     12.  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.

     13.  The Company has full corporate power and authority to: (a) enter
into the Agreement, the Transaction Agreement, the Purchase Contract Agreement,
the Purchase Contracts, the Pledge Agreement, the Remarketing Agreement and the
Indenture, (b) issue the Units and the Common Stock issuable pursuant to the
Purchase Contracts and to incur the indebtedness evidenced by the Senior Notes
and (c) make the Contract Adjustment Payments. The Agreement, the Transaction
Agreement, the Purchase Contract Agreement, the Purchase Contracts, the Pledge
Agreement, the Remarketing Agreement and the Indenture 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.

     14.  The execution and delivery by the Company of, and the performance
by the Company of its agreements in, the Agreement, the Transaction Agreement,
the Purchase Contract Agreement, the Purchase Contracts, the Pledge Agreement,
the Remarketing Agreement and the Indenture 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

                                       B-3



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.

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

     16.  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.

     17.  The Indenture has been duly qualified under the Trust Indenture Act.

     18.  The Corporate Units have been duly authorized for listing on the
New York Stock Exchange upon official notice of issuance.

     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 Units, (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

                                       B-4



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 5 and 8 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 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 the foregoing opinion, such counsel has not
examined the Units, except a specimen thereof, and has relied upon a certificate
of the trustee under the Indenture as to the authentication of the Senior Notes
and a certificate of the Purchase Contract Agent under the Purchase Contract
Agreement as to the authentication of the Units. For purposes of paragraph 4 and
14(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 Units. 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.

                                       B-5



     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.

                                       B-6



                                                                       EXHIBIT C
