                         ONEOK Inc., WESTERN RESOURCES
                          ANNOUNCE STRATEGIC ALLIANCE


                   STOCK TRANSACTION VALUED AT $660 MILLION,
             ONEOK BECOMES NINTH-LARGEST GAS DISTRIBUTOR IN NATION,
               WESTERN RESOURCES BECOMES LARGEST ONEOK SHAREOWNER


         TULSA, Oklahoma and TOPEKA, Kansas -- ONEOK Inc., (NYSE:OKE) and
 Western Resources (NYSE: WR) today announced a strategic alliance combining
 the natural gas assets of both companies. According to terms of the $660
 million transaction, ONEOK will own and operate the natural gas assets of
 Western Resources located in Kansas and northeast Oklahoma. Western Resources
 will become the largest equity holder of ONEOK through a combination of common
 and convertible preferred stock.

         The strategic alliance will position each company to maximize its
 respective strengths as energy service companies. ONEOK will provide natural
 gas and Western Resources will provide electric energy products, security
 products and other unregulated services. The agreement, expected to be
 positive to earnings for both ONEOK's and Western Resources' shareowners in
 the first year, has received approval from both companies' boards of
 directors.

         "As we continue to grow our respective companies, it is important to
innovate," said John E. Hayes, Jr., Western Resources chairman of the board and
chief executive officer. "This strategic alliance allows us to market
electricity, security and other unregulated services to a new set of customers
- -- ONEOK's 735,000 customers. In addition, Western Resources will pursue its
plan to market electricity, security and natural gas nationally. Under this
plan, ONEOK will procure natural gas for Western Resources' national marketing
effort."

         "The strategic alliance positions the respective strengths of each
management team to capitalize on the opportunities in a marketplace that is
becoming more competitive," said Larry Brummett, ONEOK chairman of the board,
president and chief executive officer. "Western Resources is an excellent
company, with competitive electric costs and an innovative management. We are
extremely pleased with this agreement and look forward to making it happen."

         Specific transaction terms include:

o        ONEOK Inc. will receive all the natural gas assets of Western
         Resources, making it the ninth largest gas distribution company in the
         United States serving 1.4 million customers.

o        ONEOK's independence is preserved by standstill provisions which
         define the rights and responsibilities of the respective companies.
         The standstill has an initial term of 15 years.

o        Western Resources will receive approximately 3 million new shares of 
         ONEOK common stock and preferred stock convertible upon necessary 
         regulatory approvals into approximately another 19.3 million shares of
         ONEOK common stock.

o        Western Resources will receive a preferred dividend of 1.5 times the
         underlying common dividend, but in no event less than $1.80 per
         preferred share per year for the first five years under the terms of
         the preferred stock.

o        Upon closing, Western Resources will nominate two directors to the
         ONEOK board of directors. If the preferred stock converts to common,
         Western Resources may designate an additional two directors.


         The agreement requires approvals from ONEOK shareholders, the Oklahoma
Corporation Commission, the Kansas Corporation Commission, and the Securities
and Exchange Commission, and anticipated the transaction will close by
mid-1997.

         Brummett said the transaction confirms ONEOK's strategy of pursuing
strategic alliances or acquisition opportunities in natural gas distribution and
energy-related businesses. Additionally, it strengthens ONEOK's balance sheet
for future cash transactions.

         According to Hayes, the transaction significantly strengthens Western
Resources' annual cash flow.

         The natural gas assets of Western Resources include natural gas
distribution properties serving 624,000 customers encompassing two-thirds of
Kansas and 36,000 customers in the northeastern corner of Oklahoma with 10,068
miles of pipeline; a natural gas transmission and gathering system with 976
miles of pipeline; a Kansas gas processing plant with a 15 million

cubic feet million cubic feet per day capacity; and a 42 percent

                                    AGREEMENT

          THIS AGREEMENT, dated as of December 12, 1996 (the "Agreement"), by
and between ONEOK Inc., a Delaware corporation ("ONEOK") and Western Resources,
Inc., a Kansas corporation ("WRI").

          WHEREAS, WRI is engaged in the business of local natural gas
distribution in the States of Kansas and Oklahoma (such business, other than the
Excluded Assets and the Retained Liabilities (as such terms are hereinafter
defined) associated therewith, and the business and operations of the
Transferred Subsidiaries (as such term is hereinafter defined), shall be
referred to herein as the "Gas Business");

          WHEREAS, WRI owns, either directly or indirectly, 100% of the
outstanding capital stock of Westar Gas Marketing, Inc. ("Westar") and Mid
Continent Marketing Center, Inc. ("MCMC"; and, together with Westar, the
"Transferred Subsidiaries") (such stock shall be referred to herein as the
"Transferred Stock");

          WHEREAS, ONEOK and WRI have determined to engage in a strategic
business combination in which the Gas Business will be combined with the
business and assets of ONEOK;

          WHEREAS, in furtherance thereof, (i) immediately prior to the Merger
Effective Time (as such term is hereinafter defined), WRI will transfer or cause
to be transferred to WAI, Inc., a corporation to be organized by WRI under the
laws of the state of Oklahoma prior to the Closing (as such term is hereinafter
defined) ("NewCorp") all of the Assets (as such term is hereinafter defined) and
WRI will cause NewCorp to assume all of the Assumed Liabilities (as such term is
hereinafter defined (such transfer and assumption, the "Asset Transaction")),
and (ii) at the Merger Effective Time, ONEOK will be merged with and into
NewCorp (the "Merger," and, together with the Asset Transaction, the
"Transactions"), with NewCorp as the surviving corporation (NewCorp, in its
capacity as such, the "Surviving Corporation");

          WHEREAS, the respective Boards of Directors of ONEOK and WRI have
approved this Agreement and the Transactions and have determined that it is in
the best interests of their respective shareholders that the Transactions be
effected under the terms and conditions of this Agreement;

          WHEREAS, for federal income tax purposes, it is intended that (i) the
Asset Transaction will be a transfer described in Section 351 of the Internal
Revenue Code of 1986, as amended (the "Code"), and (ii) the Merger will qualify
as a reorganization within the meaning of Section 368(a) of the Code; and

          WHEREAS, ONEOK and WRI desire to make certain representations,
warranties, covenants and agreements in connection with the Transactions and the
other transactions contemplated hereby and by the Ancillary Documents (as
hereinafter defined) and also to prescribe various conditions to the
Transactions and the other transactions contemplated hereby and thereby.

          1.6 Condition on Assignment or Assumption of Contracts and Rights.
Anything in this Agreement to the contrary notwithstanding, this Agreement shall
not constitute an agreement to assign or assume any claim, contract, lease,
commitment or any claim or right or any benefit arising thereunder or resulting
therefrom if an attempted assignment or assumption thereof, without the consent
of a third party thereto, would constitute a breach thereof. If such consent is
not obtained, or if an attempted assignment thereof would be ineffective or
would affect the rights of WRI or its Subsidiaries thereunder so that NewCorp or
the Surviving Corporation would not in fact receive all such rights, WRI will,
and will cause its Subsidiaries to, cooperate with the Surviving Corporation in
any arrangement reasonably designed to provide for the Surviving Corporation, at
the expense of the Surviving Corporation, the benefits under any such claims,
contracts, licenses, leases or commitments including, without limitation,
enforcement for the benefit of the Surviving Corporation of any and all rights
of WRI and its Subsidiaries against a third party thereto arising out of the
breach or cancellation by such third party or otherwise; and any transfer or
assignment to NewCorp or the Surviving Corporation by WRI or its Subsidiaries of
any property or property rights or any contract or agreement which shall require
the consent or approval of any third party, shall be made subject to such
consent or approval being obtained; provided, however, that any third party
consents to the assignment of such contracts shall provide that WRI shall be
released in full from its obligations under such contracts.

          1.7 Certain Adjustments. (a) 45 days before the Closing Date, WRI
shall prepare and deliver to ONEOK a statement (the "Statement"), certified by
an officer of WRI, setting forth the anticipated Working Capital (as such term
is hereinafter defined) of the Gas Business as of the close of business on the
Closing Date (the "Closing Working Capital"), and the dollar amount anticipated
to be expended by WRI with respect to capital expenditures and construction work
in progress relating to the Gas Business for the period from December 1, 1996,
through the Closing Date (the "WRI Capital Expenditure Amount"). ONEOK shall
prepare and deliver to WRI for inclusion on the Statement, the dollar amount
anticipated to be expended by ONEOK with respect to capital expenditures and
construction work in progress for the period from December 1, 1996, through the
Closing Date (the "ONEOK Capital Expenditure Amount") and, based on the
foregoing, WRI shall include on the Statement, the Net Amount (as such term is
hereinafter defined).

          During the 10-day period following ONEOK's receipt of the Statement,
WRI and ONEOK and their respective independent auditors shall be permitted to
review the working papers relating to the Statement. The Statement shall become
final and binding upon the parties on the tenth day following delivery thereof,
unless WRI or ONEOK gives written notice of its disagreement with the Statement
("Notice of Disagreement") to the other party prior to such date. Any Notice of
Disagreement shall specify in reasonable detail the nature of any disagreement
so asserted. If a Notice of Disagreement is received in a timely manner, then
the Statement (as revised in accordance with clause (A) or (B) below) shall
become final and binding upon ONEOK and WRI on the earlier of (A) the date ONEOK
and WRI resolve in writing any differences they have with respect to the matters
specified in each Notice of Disagreement or (B) the date any disputed matters
are finally resolved in writing by the Accounting Firm (as such term is
hereinafter defined).


                                       7
<PAGE>   19

          During the 5-day period following the delivery of a Notice of
Disagreement, ONEOK and WRI shall seek in good faith to resolve in writing any
differences which they may have with respect to the matters specified in each
Notice of Disagreement. During such period, WRI and ONEOK and their respective
auditors shall have access to the working papers of each other and its auditors
prepared in connection with the Notice of Disagreement. At the end of such 5-day
period, ONEOK and WRI shall submit to an independent accounting firm (the
"Accounting Firm") for review and resolution any and all matters which remain in
dispute and which were properly included in any Notice of Disagreement. The
Accounting Firm shall be a nationally recognized independent public accounting
firm as shall be reasonably agreed upon by ONEOK and WRI in writing. In the
event ONEOK and WRI are unable to agree upon the choice of Accounting Firm
within 2 days after the end of such 5-day period, either party may request the
American Arbitration Association to promptly choose the Accounting Firm, and the
American Arbitration Association shall promptly choose an Accounting Firm which
has not performed services for ONEOK or WRI in the last two years. Promptly, but
no later than 10 days after its acceptance of its appointment as Accounting Firm
hereunder, the Accounting Firm shall determine, based solely on presentations by
ONEOK and WRI, and not by independent review, only those issues in dispute and
shall render a report as to the dispute and the resulting computation of the
Statement, which shall be conclusive and binding upon the parties. The cost of
any dispute resolution (including the fees and expenses of the Accounting Firm
and reasonable attorney fees and expenses of the parties) pursuant to this
Section 1.7 shall be borne by ONEOK and WRI in inverse proportion to the extent
to which they may prevail on matters resolved by the Accounting Firm, which
proportionate allocations shall also be determined by the Accounting Firm at the
time the determination of the Accounting Firm is rendered on the merits of the
matters submitted.

          (b) To the extent that the Net Amount (as such term is hereinafter
defined), as specified in a Statement which becomes final pursuant to Section
1.7(a) exceeds, $40,000,000 (such excess shall be referred to herein as the
"Excess Amount"), the Surviving Corporation shall correspondingly assume at the
Closing additional debt of WRI with terms comparable to the terms of the Assumed
Debt in an aggregate principal amount equal to the Excess Amount. To the extent
the Net Amount as specified in a Statement which becomes final pursuant to
Section 1.7(a) is less than $40,000,000 (such deficiency being referred to
herein as the "Deficient Amount"), the aggregate principal amount of Assumed
Debt to be assumed by the Surviving Corporation shall be correspondingly reduced
by an amount equal to the Deficient Amount.

          (c) The term "Working Capital" shall mean Current Assets minus Current
Liabilities. The terms "Current Assets" and "Current Liabilities," for the
purpose of this Section 1.7, shall mean the current assets (exclusive of cash
and cash equivalents) and current liabilities of the Gas Business, calculated
consistently with WRI's past practice based upon the books and records of WRI
and the Consolidated Financial Information of the Gas Business. The term "Net
Amount" shall mean the Working Capital of the Gas Business as of the close of
business on the Closing Date minus the amount, if any, by which the ONEOK
Capital Expenditure Amount exceeds the WRI Capital Expenditure Amount and plus
the amount, if any, by which the WRI Capital Expenditure Amount exceeds the
ONEOK Capital Expenditure Amount, as applicable.

          1.8 Certain Taxes. ONEOK shall pay all transfer, stamp, sales or use

or performance of this Agreement or the transfer to NewCorp of the Assets
contemplated hereby pursuant to the Transfer Documents.

terms and subject to the conditions of this Agreement, at the Merger Effective
Time, ONEOK will be merged into NewCorp in accordance with the Delaware General
Corporation Law ("DGCL") and the Oklahoma General Corporation Act ("OGCA"), the

conditions to each party's obligation to consummate the Merger specified in
Article VII, by filing appropriate certificates of merger, in such form as is
required by, and executed in accordance with, the relevant provisions of the
laws of the States of Delaware and Oklahoma, as applicable. The Merger shall be
effective at such time as the foregoing certificates of merger are duly filed
with the Secretaries of State of the States of Delaware and Oklahoma, in
accordance with Delaware or Oklahoma law, as applicable, or at such later times
as specified in the foregoing certificates of merger (the "Merger Effective
Time" or "Effective Time"). The date on which the Merger Effective Time shall
occur is referred to herein as the "Merger Effective Date" or the "Effective
Date".

          2.2 Closing. The closing of the Merger (the "Closing") shall take
place at the offices of WRI as promptly as practicable after satisfaction or, to
the extent permitted hereunder, waiver of all of the conditions to each party's
obligation to consummate the Merger contained in Article VII, or at such other
place or time as the parties hereto shall agree (the date of the Closing being
referred to herein as the "Closing Date").

          2.3 Effect of the Merger. (a) At the Merger Effective Date: (i) ONEOK

Merger, which shall be in a form to be reasonably mutually agreed upon in good
faith by WRI and ONEOK prior to the Merger, which shall include the provisions

inconsistent with the terms of the Shareholder Agreement (as such term is
hereinafter defined), shall be the Certificate of Incorporation of the Surviving
Corporation (the "NewCorp Charter"), provided, however, that the Certificate of
Incorporation of NewCorp shall be amended immediately prior to the Merger to
change the name of NewCorp to "ONEOK Inc."; and (iii) the Bylaws of NewCorp in
effect immediately prior to the Merger, which shall be in a form to be

Shareholder Agreement, shall be the Bylaws of the Surviving Corporation (the

          (b) The directors and officers of the Surviving Corporation will be

however, that the Surviving Corporation shall add additional directors to the
Board of Directors of the Surviving Corporation as contemplated by the
Shareholder Agreement and 5 persons who are currently officers of WRI with
respect to the Gas Business (inclusive of the officers of the Transferred
Subsidiaries referred to in the next sentence) will be appointed as officers,
with comparable responsibilities, of the Surviving Corporation. The current
officers of the Transferred Subsidiaries will either retain their positions
post-Closing as officers of the Transferred Subsidiaries or be granted
comparable positions with the Surviving Corporation.

          (c) The Merger shall have the effect provided for in the DGCL and the
OGCA and the provisions of this Section 2.3.

                                   ARTICLE III
                            CONVERSION OF SHARES AND
                            EXCHANGE OF CERTIFICATES

          3.1 Effect of Merger on Capital Stock. At the Merger Effective Time,
by virtue of the Merger and without any action on the part of the owners of the
capital stock of ONEOK or NewCorp:

          (a) NewCorp Capital Stock Unchanged. Each issued and outstanding share
of the capital stock of NewCorp shall not be converted or otherwise affected by
the Merger and shall remain outstanding after the Merger.

          (b) Cancellation of Treasury Stock. All shares of the capital stock of
ONEOK, if any, that are owned by ONEOK as treasury stock and any share of
capital stock of ONEOK owned by any wholly-owned Subsidiary of ONEOK shall be
canceled and retired and shall cease to exist and no stock of NewCorp or other
consideration shall be delivered in exchange therefor.

          (c) Exchange of ONEOK Common Stock. Each share of Common Stock,
without par value, of ONEOK ("ONEOK Common Stock") issued and outstanding
immediately prior to the Merger Effective Time (other than shares canceled in
accordance with Section 3.1(b) above) shall be converted into one share of
common stock, no par value, of the Surviving Corporation ("NewCorp Common
Stock"), together with the corresponding number of associated rights ("NewCorp
Stock Purchase Rights") to purchase one one-hundredth of a share of NewCorp
Series A Participation Preference Stock, without par value, of the Surviving
Corporation ("NewCorp Preference Stock") pursuant to a Shareholder Protection
Rights Agreement entered into prior to the Closing between NewCorp and Liberty
Bank and Trust Company of Oklahoma City, N.A., as Rights Agent (the "NewCorp
Rights Agreement"), in a form to be reasonably mutually agreed upon in good
faith by ONEOK and WRI prior to the Merger, which shall include the provisions
summarized in Exhibit A hereto and which shall not contain other provisions
inconsistent with the terms of the Shareholder Agreement. All references in this
Agreement to the NewCorp Common Stock shall be deemed to include the associated
NewCorp Stock Purchase Rights. All such shares of ONEOK Common Stock, when so
converted, shall no longer be outstanding and shall automatically be canceled
and retired and shall cease to exist, and each holder of a certificate
representing any such shares shall cease to have any rights with respect
thereto, except the right to receive shares of NewCorp Common Stock in
accordance herewith.

          3.2 Exchange of Certificates.

          (a) Exchange of Certificates. As of the Merger Effective Time, WRI
shall cause NewCorp to deposit with such bank or trust company (the "Exchange
Agent") to be designated by ONEOK with the consent of WRI (such consent not to
be unreasonably withheld or delayed), for the benefit of the holders of shares
of ONEOK Common Stock, for exchange in accordance with this Article III, through
the Exchange Agent, certificates representing shares of NewCorp Common Stock
(such shares representing the "Stock Consideration", and together with any
dividends or distributions with respect thereto, being hereinafter referred to
as the "Exchange Fund") issuable pursuant to this Article III in exchange for
outstanding shares of ONEOK Common Stock.

          (b) Exchange Procedures. As soon as reasonably practicable after the
Merger Effective Time, the Exchange Agent shall mail to each holder of record of
a certificate or certificates which, immediately prior to the Merger Effective
Time, represented outstanding shares of ONEOK Common Stock (the "Certificates"),
which holder's shares of ONEOK Common Stock were converted into the right to
receive the same number of shares of NewCorp Common Stock (Stock Consideration):
(i) a letter of transmittal (which shall specify that delivery shall be effected
and risk of loss and title to the Certificates shall pass only upon delivery of
the Certificates to the Exchange Agent, and shall be in such form and have such
other provisions as ONEOK or the Surviving Corporation may reasonably specify);
and (ii) instructions for use in effecting the surrender of the Certificates in
exchange for the Stock Consideration. Upon surrender of a Certificate for
cancellation to the Exchange Agent, together with such letter of transmittal,
duly executed, and any other required documents, the holder of such Certificate
shall be entitled to receive in exchange therefor a certificate representing
that number of whole shares of NewCorp Common Stock which such holder has the
right to receive pursuant to the provisions of this Article III and the
Certificate so surrendered shall forthwith be canceled. In the event of a
transfer of ownership of ONEOK Common Stock which is not registered in the
transfer records of ONEOK, a certificate representing the appropriate number of
shares of NewCorp Common Stock may be issued to a transferee if the Certificate
representing such shares is presented to the Exchange Agent accompanied by all
documents required to evidence and effect such transfer and by evidence that any
applicable stock transfer taxes have been paid. Until surrendered as
contemplated by this Section 3.2, each Certificate shall be deemed at any time
after the Merger Effective Time to represent only the right to receive upon such
surrender the Stock Consideration. The Exchange Agent shall not be entitled to
vote or exercise any rights of ownership with respect to the NewCorp capital
stock held by it from time to time hereunder, except that it shall receive and
hold all dividends or other distributions paid or distributed with respect
thereto for the account of persons entitled thereto.

          (c) Distributions with Respect to Unexchanged Shares. No dividends or
other distributions with respect to NewCorp Common Stock declared or made after
the Merger Effective Time with a record date after the Merger Effective Time
shall be paid to the holder of any unsurrendered Certificate until the holder of
such Certificate shall surrender such Certificate. Subject to the effect of
applicable laws, following surrender of any such Certificate, there shall be
paid to the holder thereof, without interest, if such holder is entitled to
receive the Stock Consideration: (i) at the time of such surrender, the amount
of dividends or other distributions with a record date after the Merger
Effective Time theretofore paid with respect to such whole shares of such Stock
Consideration; and (ii) at the appropriate payment date, the amount of dividends
or other distributions with a record date after the Merger Effective Time but
prior to surrender and a payment date subsequent to surrender payable with
respect to such whole shares of NewCorp Common Stock.

          (d) No Further Ownership Rights in ONEOK Common Stock. All shares of
NewCorp Common Stock issued upon the surrender for exchange of shares of ONEOK
Common Stock in accordance with the terms hereof shall be deemed to have been
issued in full satisfaction of all rights pertaining to such shares of ONEOK
Common Stock, subject, however, to the Surviving Corporation's right to pay any
dividends or make any other distributions with a record date on or prior to the
Merger Effective Time that may have been declared or made by ONEOK on such
shares of ONEOK Common Stock in accordance with the terms of this Agreement and
which remain unpaid at the Merger Effective Time, and after the Merger Effective
Time there shall be no further registration of transfers on the stock transfer
books of the Surviving Corporation of the shares of ONEOK Common Stock that were
outstanding immediately prior to the Merger Effective Time. If, after the Merger
Effective Time, Certificates are presented to the Surviving Corporation for any
reason, they shall be canceled and exchanged as provided in this Article III.

          (e) Termination of Exchange Agent. Any portion of the Exchange Fund
that remains undistributed to the former stockholders of ONEOK for one year
after the Merger Effective Time shall be delivered to the Surviving Corporation
which shall after the Merger Effective Time act as the Exchange Agent, and any
former stockholders of ONEOK who have not complied with this Article III prior
to the Merger Effective Time shall thereafter look only as a general creditor to
the Surviving Corporation for payment of their claim for the Stock Consideration
and any dividends or distributions with respect to NewCorp Common Stock if such
holder is entitled to receive the Stock Consideration.

          (f) No Liability. None of ONEOK, WRI or the Surviving Corporation
shall be liable to any holder of shares of ONEOK Common Stock for such shares
(or dividends or distributions with respect thereto), delivered to a public
official pursuant to any applicable abandonment, escheat or similar law. Any
amounts remaining unclaimed by holders of any such shares six years after the
Merger Effective Time (or such earlier date immediately prior to the time at
which such amounts would otherwise escheat to or become property of any
governmental entity) shall, to the extent permitted by applicable law, become
the property of the Surviving Corporation free and clear of any claims or
interest of any such holders or their successors, assigns or personal
representatives previously entitled thereto.

warrants to WRI as follows, except as set forth in the disclosure schedule to be
signed by an authorized officer of ONEOK and delivered to WRI by ONEOK (the
"ONEOK Disclosure Schedule") pursuant to Section 6.22, each of which exceptions
shall specifically identify the relevant Section hereof to which it relates:

          (a) Organization, Standing and Power. Each of ONEOK and its
Significant Subsidiaries is a corporation or partnership duly organized, validly
existing and in good standing under the laws of its state of incorporation or
organization, has all requisite power and authority to own, lease and operate
its properties and to carry on its business as now being conducted, and is duly
qualified and in good standing to do business in each jurisdiction in which the
business it is conducting, or the operation, ownership or leasing of its
properties, makes such qualification necessary, other than in such jurisdictions
where the failure so to qualify would not have a Material Adverse Effect on
ONEOK. ONEOK has heretofore delivered to WRI complete and correct copies of
ONEOK's and its Significant Subsidiaries' certificates of incorporation and
bylaws, each as amended and in full force and effect on the date hereof. All
Significant Subsidiaries of ONEOK and their respective jurisdictions of
incorporation or organization are identified on Section 4.1(a) of the ONEOK

ONEOK stockholders may vote were issued or outstanding. All such issued and

issued, fully paid and nonassessable and are not subject to preemptive rights.
Other than 148,482 shares of Preference Stock, ONEOK has no shares of Common

Subsidiaries of ONEOK are owned by ONEOK, or a direct or indirect wholly owned
Subsidiary of ONEOK, free and clear of all Liens, and are validly issued, fully
paid and nonassessable and are not subject to preemptive rights. Except (i) as
set forth above and as contemplated by the ONEOK Rights Agreement, (ii) for

options granted pursuant to, or from issuance or purchases under, the ONEOK
Stock Plans and ONEOK's Direct Stock Purchase and Dividend Reinvestment Plan,

to issue, deliver, sell, purchase, redeem or acquire, or cause to be issued,
delivered, sold, purchased, redeemed or acquired, additional shares of its
capital stock or any securities of ONEOK or any Subsidiary of ONEOK exercisable
for, exchangeable for or convertible into such capital stock, or obligating
ONEOK or any Subsidiary of ONEOK to grant, extend or enter into any such option,
warrant, call, subscription, convertible securities, or other right, commitment
or agreement. Except with respect to the Shareholder Agreement, there are not as
of the date hereof and there will not be at the Merger Effective Time any
stockholder agreements, voting trusts or other agreements or understandings to
which ONEOK is a party or by which it is bound relating to the voting of any
shares of the capital stock of ONEOK that will limit in any way the solicitation
of proxies by or on behalf of ONEOK from, or the casting of votes by, the
stockholders of ONEOK with respect to the Merger. There are no restrictions on
ONEOK to vote the stock of any of its Subsidiaries.

          the best interest of the stockholders of ONEOK. ONEOK has and will
          have all requisite corporate power and authority to enter into this
          Agreement and the other agreements contemplated hereby, including the

          Services Agreement (as such term is hereinafter defined), the Transfer
          Documents, the Shareholder Agreement, the Employee Agreement (as such
          term is hereinafter defined) and the Environmental Indemnity Agreement
          (as such term is hereinafter defined) (collectively, the "Ancillary
          Documents") to the extent it is a party thereto, to perform its
          obligations hereunder and thereunder and to consummate the
          Transactions and the other transactions contemplated hereby and
          thereby, subject to the approval of this Agreement and the Merger by
          the holders of a majority of the voting power of the ONEOK Common
          Stock, assuming the redemption of the ONEOK Preferred Stock as
          contemplated by Section 5.2(d), in accordance with the DGCL and
          ONEOK's certificate of incorporation and bylaws, as amended (the
          "ONEOK Stockholder Approval"). The execution and delivery of this
          Agreement and each Ancillary Document to which ONEOK is a party, the
          performance of obligations hereunder and thereunder by ONEOK and the
          consummation of the Transactions and the other transactions
          contemplated hereby and thereby have been duly authorized by all
          necessary corporate action on the part of ONEOK, subject to the ONEOK
          Stockholder Approval. This Agreement has been duly executed and
          delivered by ONEOK and, subject to the ONEOK Stockholder Approval,
          constitutes and the Ancillary Documents to which ONEOK is a party,
          when executed and delivered by ONEOK, will constitute, valid and
          binding obligations of ONEOK, enforceable against ONEOK in accordance
          with their respective terms, subject, in each case, as to
          enforceability, to bankruptcy, insolvency, reorganization and other
          laws of general applicability relating to or affecting creditors'
          rights and to general principles of equity (assuming such documents
          constitute a valid and binding obligation on the other parties
          thereto).

               (2) The execution and delivery of this Agreement and the
          Ancillary Documents to which ONEOK is a party do not, and the
          consummation of the Transactions and the other contemplated hereby and
          thereby and compliance with the provisions hereof and thereof will
          not, conflict with, or result in any violation of, or default (with or
          without notice or lapse of time, or both) under, or change the rights
          or obligations of any party under, or give rise to a right of
          termination, cancellation or acceleration of any obligation or to the
          loss of a material benefit under, or result in the creation of any
          Lien, upon any of the properties or assets of ONEOK or any of its
          Subsidiaries under, any provision of (A) the certificate of
          incorporation or bylaws of ONEOK, as amended, or any provision of the
          charter or other organizational documents of any of its Subsidiaries,
          (B) subject to obtaining the third-party consents set forth in Section
          4.1(c)(2) of the ONEOK Disclosure Schedule (the "ONEOK Required
          Consents"), any loan or credit agreement, note, bond, mortgage,
          indenture, lease or other material agreement, instrument, permit,
          franchise or license applicable to ONEOK or any of its Subsidiaries or
          (C) assuming the consents, approvals, authorizations or permits and
          filings or notifications referred to in Section 4.1(c)(3) of the ONEOK
          Disclosure Schedule are duly and timely obtained or made and the ONEOK
          Stockholder Approval has been obtained, any judgment, order, decree,
          statute, law, ordinance, rule or regulation applicable to ONEOK or any
          of its Subsidiaries or any of their respective properties or assets,
          other than, in the case of clause (B) or (C), any such conflicts,
          violations, defaults, rights, or Liens, that, individually or in the
          aggregate, would not have a Material Adverse Effect on ONEOK,
          materially impair the ability of ONEOK to perform its obligations
          hereunder or under any Ancillary Document to which ONEOK is a party or
          prevent the consummation of any of the Transactions and the other
          transactions contemplated hereby or thereby.

          other administrative proceedings or court proceedings are presently
          pending with regard to any Taxes for which ONEOK or any of its
          Subsidiaries could be liable, and except as provided for in the ONEOK

          ONEOK or any of its Subsidiaries could be liable or (B) a closing
          agreement pursuant to Section 7121 of the Code, or any predecessor
          provision thereof or any similar provision of state or local Tax law
          that relates to the assets or operations of ONEOK or any of its
          Subsidiaries.

               (4) Neither ONEOK nor any of its Subsidiaries has made an
          election under Section 341(f) of the Code or agreed to have Section

               (5) Except as set forth in the ONEOK SEC Documents or Section
          4.1(k)(5) of the ONEOK Disclosure Schedule, neither ONEOK nor any of
          its Subsidiaries is a party to, is bound by or has any obligation
          under any tax sharing agreement or similar agreement or arrangement
          which has as a party a person other than ONEOK or any of its
          Subsidiaries.

               (6) Section 4.1(k)(6) of the ONEOK Disclosure Schedule sets forth
          a list of federal, state, local or foreign jurisdictions in which
          ONEOK and its Subsidiaries have paid any Taxes or filed any Returns

          4.1(k)(6) of the ONEOK Disclosure Schedule has made a claim, assertion
          or, to the knowledge of ONEOK and its Subsidiaries, threat that ONEOK
          or its Subsidiaries is subject to taxation in such jurisdiction.

               (7) Except as disclosed in Section 4.1(k)(7) of the ONEOK
          Disclosure Schedule, neither ONEOK nor any of its Subsidiaries

          payments under which would not be expected to be deductible as a
          result of the limitation of Section 162(m) of the Code and the
          regulations issued thereunder.

               (8) Except as disclosed in Section 4.1(k)(8) of the ONEOK
          Disclosure Schedule, as a result, directly or indirectly, of the
          Transactions or the other transactions contemplated by this Agreement
          (including without limitation, any terminations of employment prior to
          or following the Merger Effective Time), none of ONEOK, its
          Subsidiaries or NewCorp will be obligated to make a payment (including
          without limitation any acceleration of vesting or payment) with
          respect to employees of ONEOK or its Subsidiaries who are
          "disqualified individuals" that would be characterized as an "excess
          parachute payment" (as such terms are defined in Section 280G of the
          Code).

For purposes of this Agreement, (i) "Taxes" shall mean any federal, state, local

          or will be timely made in accordance with Section 404(a)(6) of the
          Code.

               (3) Qualification; Compliance. The following representations
          apply to ONEOK Benefit Plans being continued by NewCorp or for which
          NewCorp may have liability.

               a.   Each ONEOK Benefit Plan that is intended to be "qualified"
                    within the meaning of Section 401(a) of the Code (1)
                    currently meets all qualification requirements under the
                    Code both in form and in operation, except any failure that
                    can be corrected without material liability, and (2) has
                    received a favorable determination letter from the IRS on
                    its qualification or application for such a determination
                    has been made prior to the expiration of the applicable
                    remedial amendment period, and to the knowledge of ONEOK

                    revocation of any such favorable determination letter.

               b.   Each ONEOK Benefit Plan is and has been operated in
                    compliance with, all applicable laws, rules and regulations
                    governing such plan, including, without limitation, ERISA
                    and the Code, and all filings, disclosures and notices
                    required have been timely made, except for violations that
                    would not have a Material Adverse Effect on ONEOK. All
                    amendments and actions required to bring each of the ONEOK
                    Benefit Plans into conformity with all of the applicable
                    provisions of ERISA and the Code and other applicable legal
                    requirements have been made or taken except to the extent
                    that such amendments or actions are not required by law to
                    be made or taken until a date after the Merger Effective
                    Time and except for actions the failure of which to take
                    would not have a Material Adverse Effect on ONEOK.

               c.   To the knowledge of ONEOK, no individual or entity has
                    engaged in any transaction in connection with which ONEOK or
                    any ONEOK Affiliate, or any ONEOK Benefit Plan or any trust,
                    trustee or administrator thereof, could be subject to
                    liability pursuant to Section 409 or Section 502 of ERISA,
                    or subject to an excise tax pursuant to Section 4975 of the
                    Code, which could in either case have a Material Adverse
                    Effect on ONEOK.

               d.   Except for matters that would not have a Material Adverse
                    Effect on ONEOK:

                    1.   To the knowledge of ONEOK, no ONEOK Benefit Plan is
                         subject to any ongoing audit, investigation or other
                         administrative proceeding of the IRS, the Department of
                         Labor or any other Governmental Entity or, to the
                         knowledge of ONEOK, is scheduled to be subject to such
                         an audit, investigation or proceeding; and

                    2.   No ONEOK Benefit Plan is the subject of any pending
                         application for administrative relief under any
                         voluntary compliance program of any Governmental Entity
                         (including, without limitation, the IRS' Voluntary
                         Compliance Resolution Program or Walk-in Closing
                         Agreement Program, or the Department of Labor's
                         Delinquent Filer Voluntary Compliance Program).

               (4) Pension Benefit Plan; Liabilities. Except as set forth in
          Section 4.1(l)(4) of the ONEOK Disclosure Schedule, with respect to
          the ONEOK Pension Benefit Plans, individually and in the aggregate, no
          termination or partial termination of any ONEOK Pension Benefit Plan
          has occurred and no event has occurred that would be reasonably
          expected to subject ONEOK or any ONEOK Affiliate to any liability
          arising under the Code, ERISA or any other applicable law (including,
          without limitation, any liability to or under any such plan or to the
          PBGC, or under any indemnity agreement to which ONEOK or any ONEOK
          Affiliate is a party), which liability could have a Material Adverse
          Effect on ONEOK (excluding liability for benefit claims and funding
          obligations payable in the ordinary course and liability for PBGC
          insurance premiums payable in the ordinary course).

               (5) Welfare Plans. To the knowledge of ONEOK, no circumstances
          exist that could subject ONEOK or any ONEOK Affiliate to an excise tax
          under Section 4976 of the Code that would have a Material Adverse
          Effect on ONEOK.

               (6) Documents Made Available. ONEOK has made available to WRI a
          true and correct copy of each collective bargaining agreement to which
          ONEOK or any ONEOK Affiliate is a party and under which ONEOK has
          obligations or joint and several liability; and, with respect to each
          ONEOK Benefit Plan, ONEOK has made available to WRI a true and correct
          copy of each of the following, as applicable:

                    prepared summary plan description and all summaries of
                    material modifications prepared since the most recent
                    summary plan description;

                    letter with respect to the qualified status under Code
                    Section 401(a) of such plan or under Code Section 501 of the
                    related trust;

          Section 4.1(l)(7) of the ONEOK Disclosure Schedule or as provided
          under any ONEOK Benefit Plan or any agreement described in Section
          4.1(l)(1)c. above, the consummation or announcement of any transaction
          contemplated by this Agreement will not directly or indirectly (either
          alone or upon the occurrence of any additional or further acts or
          events) result in any:


                                       24
<PAGE>   36

               a.   payment (whether of severance pay or otherwise) becoming due
                    from ONEOK or any ONEOK Affiliate to any current or former
                    officer, director, employee or independent contractor of
                    ONEOK or any ONEOK Affiliate or to the trustee under any
                    "rabbi trust" or other funding arrangement, which would
                    reasonably be expected to result in liability to NewCorp; or

               b.   benefit under any ONEOK Benefit Plan being established or
                    increased or becoming accelerated, vested or payable, except

                    the same terms and conditions without regard to the
                    transactions contemplated by this Agreement, which would
                    reasonably be expected to result in liability to NewCorp.

               (8) Funded Status of Plans. Except as disclosed in Section
          4.1(l)(8) of the ONEOK Disclosure Schedule, (A) each ONEOK Pension
          Benefit Plan has been maintained in compliance with the minimum
          funding standards of ERISA and the Code, (B) no ONEOK Pension Benefit
          Plan has incurred any "accumulated funding deficiency" (within the
          meaning of Section 302 of ERISA or Section 412 of the Code) and (C)
          all required payments to the PBGC with respect to each ONEOK Pension
          Benefit Plan have been made on or before their due dates, in each case
          with respect to ONEOK Pension Benefit Plans which would reasonably be
          expected to result in liability to ONEOK or any ONEOK Subsidiary.
          Except as disclosed in Section 4.1(l)(8) of the ONEOK Disclosure
          Schedule, neither ONEOK nor any of its Subsidiaries has provided, or
          is required to provide, security to any ONEOK Pension Benefit Plan

               (9) Multiemployer Plans. Except as disclosed in Section 4.1(l)(9)
          of the ONEOK Disclosure Schedule, no ONEOK Benefit Plan is a
          "multiemployer plan" (within the meaning of Section 4001(a)(3) of
          ERISA), a multiple employer plan described in Section 413(c) of the
          Code or a "multiple employer welfare arrangement" (within the meaning
          of Section 3(40) of ERISA); and none of ONEOK or any ONEOK Affiliate
          is obligated to contribute to, has incurred or is expected to incur
          any withdrawal liability or has had any liability under Title IV of
          ERISA with respect to, or any liability in connection with the
          reorganization or termination of, any multiemployer plan, multiple
          employer plan, or multiple employer welfare arrangement.

               (10) Modification or Termination of Plans. Except as disclosed in
          Section 4.1(l)(10) of the ONEOK Disclosure Schedule or as required
          pursuant to a collective bargaining agreement or as required to secure
          a favorable determination letter from the IRS, neither ONEOK nor any
          ONEOK Affiliate is subject to any legal obligation, or has any formal
          plan, to enter into any form of material compensation or employment
          agreement or to establish any employee benefit plan of any nature,
          including (without limitation) any pension, profit sharing, welfare,
          post-retirement welfare, stock option, stock or cash award,
          non-qualified deferred compensation or executive compensation plan,
          policy or practice or to modify or change any existing ONEOK Benefit
          Plan and, to the knowledge of ONEOK, there has been no communication
          to employees by ONEOK or any ONEOK Affiliate that would reasonably be

          (v) Beneficial Ownership of WRI Common Stock. Neither ONEOK nor any of
its Subsidiaries "beneficially owns" (as defined in Rule 13d-3 under the
Exchange Act) any outstanding shares of WRI Common Stock.

          (w) Brokers. Except for the fees and expenses payable to PaineWebber
Incorporated, which fees are reflected in its agreement with ONEOK, no broker,
investment banker or other person is entitled to any broker's, finder's or other
similar fee or commission in connection with the negotiations leading to this
Agreement or the consummation of the Transactions or the other transactions
contemplated by this Agreement based upon arrangements made by or on behalf of
ONEOK or any of its Subsidiaries.

          (x) Related Party Transactions. There are no contracts, arrangements
or transactions in effect between ONEOK or any of its Subsidiaries, on the one
hand, and any officer, director or 5% stockholder of ONEOK, or any Affiliate or
immediate family member of any of the foregoing persons, on the other hand,
except as set forth in Section 4.1(x) of the ONEOK Disclosure Schedule.

          (y) Takeover Provisions. No "fair price," "moratorium," "control share
acquisition" or other similar anti-takeover statute or regulation (each a
"Takeover Statute") or any applicable anti-takeover provision in ONEOK's
certificate of incorporation or bylaws, as amended, is, or at the Merger
Effective Time will be, applicable to ONEOK, the shares of ONEOK's capital
stock, the Merger or the other transactions contemplated by this Agreement or

          (aa) Title to Properties.

               (1) ONEOK and its Subsidiaries, individually or together, have
          good and sufficient title to all of the assets that they purport to
          own, including all of the properties and assets reflected in the
          balance sheet as of August 31, 1996, included in the ONEOK Balance
          Sheet, and all properties and assets purchased or otherwise acquired
          since August 31, 1996. Such assets are sufficient to enable ONEOK and
          its Subsidiaries to conduct the business of ONEOK or its Subsidiaries
          as currently conducted without material interference, free and clear
          of Liens, other than Permitted Liens. ONEOK and its Subsidiaries,
          individually or together, hold under valid lease agreements all of
          their real and personal properties reflected in the ONEOK Balance
          Sheet, and all real and personal property that is subject to the
          operating leases to which reference is made in the notes to the ONEOK
          Balance Sheet, and enjoy peaceful and undisturbed possession of such
          properties under such leases, other than any properties as to which
          such leases will have terminated in the ordinary course since the date
          of the ONEOK Balance Sheet. None of ONEOK, its Subsidiaries or any of
          their predecessors has received any written notice of any adverse
          claim to the title to any properties owned by them or with respect to
          any lease under which any properties are held by them, other than any
          claims that, individually or in the aggregate, would not have a
          Material Adverse Effect on ONEOK. For the purposes hereof, the term
          "Lien" shall mean any mortgage, pledge, security interest,
          encumbrance, lien, claim, condition, equity interest, option, right of
          first refusal, charge or restriction of any kind (including any
          agreement to give any of the foregoing), any conditional sale or other
          title retention agreement, any lease in the nature thereof or the
          filing of or agreement to give any financing statement under the
          Uniform Commercial Code of any jurisdiction, and the term "Permitted
          Liens" shall mean (i) Liens for taxes and assessments, general and
          special, not yet due and payable, and (ii) Liens, encumbrances and
          other defects which, individually or in the aggregate, do not and will
          not materially interfere with or impair the continued ownership,
          possession, use or operation of the assets as such assets are used in
          the business of ONEOK or the Gas Business, as applicable.

               (2) Neither ONEOK nor any of its Subsidiaries is in violation of
          the terms of any Easement except any such violations that,
          individually or in the aggregate, would not have a Material Adverse
          Effect on ONEOK. Except as would not have a Material Adverse Effect on
          ONEOK, all Easements in favor of ONEOK are valid and enforceable and
          grant the rights purported to be granted thereby and all rights
          necessary thereunder for the operation of the business of ONEOK.
          Except as would not have a Material Adverse Effect on ONEOK, to the
          knowledge of ONEOK, there are no spatial gaps in the Easements in
          favor of ONEOK that would have a Material Adverse Effect on ONEOK and
          all parts of the pipeline assets which constitute a portion of the
          assets of ONEOK and its Subsidiaries are located either on property
          which is owned in fee by ONEOK or its Subsidiaries or on property
          which is subject to an Easement in favor of ONEOK or its Subsidiary.

          (ab) Condition of Assets. To the knowledge of ONEOK and its
Subsidiaries, the buildings, plants, structures, and equipment of ONEOK and its
Subsidiaries are structurally sound, are in good operating condition and repair,
and are adequate for the uses to which they are being put, and none of such
buildings, plants, structures, or equipment is in need of maintenance or repairs
except for ordinary, routine maintenance and repairs that are not material in
nature or cost.

          (ac) Accounts Receivable. All Accounts Receivable of ONEOK represent
or will represent valid obligations arising from sales actually made or services
actually performed in the ordinary course of the business of ONEOK. Unless paid
prior to the Closing, the Accounts Receivable are or will be, as of the Closing,
collectible, subject only to allowance for doubtful accounts, and calculated
consistently with past practice. There is no contest, claim or right of set-off,
under any contract or with any obligor of an Account Receivable relating to the
amount or validity of such Accounts Receivable, which would have a Material
Adverse Effect on ONEOK.

          4.2 Representations and Warranties of WRI. WRI represents and warrants
to ONEOK as follows, except as set forth in the disclosure schedule to be signed
by an authorized officer of WRI and delivered to ONEOK by WRI (the "WRI
Disclosure Schedule") pursuant to Section 6.22, each of which exceptions shall
specifically identify the relevant Section hereof to which it relates:

          (a) Organization, Standing and Power. Each of WRI, Westar, MCMC and
the Significant Subsidiaries of Westar and MCMC, is, and NewCorp at the Closing
will be, a corporation duly organized, validly existing and in good standing
under the laws of its respective state of incorporation or organization, has,
and NewCorp at the Closing will, subject, with respect to NewCorp, to the
satisfaction of the closing conditions, have, all requisite power and authority
to own, lease and operate its properties and to carry on its business as now
being conducted, and is, and NewCorp at the Closing will be, duly qualified and
in good standing to do business in each jurisdiction in which the business it is
conducting, or the operation, ownership or leasing of its properties, makes such
qualification necessary, other than in such jurisdictions where the failure so
to qualify would not have a Material Adverse Effect on the Gas Business. WRI has
heretofore delivered to ONEOK complete and correct copies of its articles of
incorporation and bylaws, as amended to the date hereof. WRI has heretofore
delivered to ONEOK complete and correct copies of the certificate of
incorporation and bylaws of each of Westar and MCMC each, as amended and in full
force and effect as of the date hereof.

          (b) Capital Structure. Subject to the provisions of the Shareholder
Agreement, after giving effect to the Asset Transaction and the Merger and the
other transactions contemplated by this Agreement, immediately after the
Closing, (i) 2,996,702 shares of NewCorp Common Stock will be issued and
outstanding and owned by WRI and the remaining then outstanding shares of
NewCorp Common Stock shall constitute the Stock Consideration issued and/or
issuable to the shareholders of ONEOK pursuant to Article III and (ii)
19,317,584 shares of Convertible Preferred Stock, Series A will be issued and
outstanding and owned by WRI. As of the date hereof, the authorized capital
stock of Westar consists of 1,000 shares of common stock, without par value, of
which 1,000 shares of common stock are issued and outstanding and owned by
Westar Energy Inc., a wholly-owned Subsidiary of WRI. As of the date hereof, the
authorized capital stock of MCMC consists of 1,000 shares of common stock,
without par value, of which 1,000 shares of common stock are issued and
outstanding and owned by WRI. All issued and outstanding shares of the
Transferred Stock are validly issued, fully paid and nonassessable and are not
subject to preemptive rights. Upon the transfer by WRI of the Transferred Stock
to NewCorp at the Closing, pursuant to the Transfer Documents, NewCorp will own
the Transferred Stock, free and clear of all Liens.

<PAGE>   46

          (c) Sufficiency of Assets. Except as disclosed in Section 4.2(c) of
the WRI Disclosure Schedule, the Assets to be transferred to NewCorp pursuant to
the Asset Transaction will constitute all of the assets and properties of WRI
and its Subsidiaries (other than the Excluded Assets) that are primarily used
in, or primarily related to, or primarily generated by the field operations of
the Gas Business as conducted by WRI immediately prior to the Asset Transaction.

          (d) Authority; No Violations; Consents and Approvals.

               (1) The Board of Directors of WRI has approved the Merger and
          this Agreement. WRI has and will have all requisite corporate power
          and authority to enter into this Agreement and the Ancillary Documents
          to the extent it is a party thereto, to perform its obligations
          hereunder and thereunder and to consummate the transactions
          contemplated hereby and thereby. The execution and delivery of this
          Agreement and each Ancillary Document to which WRI is a party, the
          performance of obligations hereunder and thereunder by WRI and the
          consummation of the Transactions and the other contemplated hereby and
          thereby have been duly authorized by all necessary corporate action on
          the part of WRI. This Agreement has been duly executed and delivered
          by WRI and constitutes, and the Ancillary Documents to which WRI is a
          party when executed and delivered by WRI, will constitute, valid and
          binding obligations of WRI, enforceable against WRI in accordance with
          their respective terms, subject, in each case, as to enforceability,
          to bankruptcy, insolvency, reorganization and other laws of general
          applicability relating to or affecting creditors' rights and to
          general principles of equity (assuming such documents constitute a
          valid and binding obligation on the other parties thereto).

               (2) The execution and delivery of this Agreement and the
          Ancillary Documents to which WRI is a party do not, and the
          consummation of the Transactions and the other transactions
          contemplated hereby and thereby and compliance with the provisions
          hereof and thereof will not, conflict with, or result in any violation
          of, or default (with or without notice or lapse of time, or both)
          under, or change the rights or obligations of any party under, or give
          rise to a right of termination, cancellation or acceleration of any
          obligation or to the loss of a material benefit under, or result in
          the creation of any Lien upon any of the properties or assets of the
          Gas Business under, any provision of (A) the certificates of
          incorporation or bylaws of WRI, Westar, MCMC, as amended, or any
          provision of the charters or organizational documents of any of the
          respective Subsidiaries of Westar or MCMC, (B) subject to obtaining
          the third-party consents set forth in Section 4.2(d)(2) of the WRI
          Disclosure Schedule and the assignments of contracts, in the manner
          contemplated by Section 1.6 of this Agreement (the "WRI Required
          Consents"), any loan or credit agreement, note, bond, mortgage,
          indenture, lease or other material agreement, instrument, permit,
          franchise or license applicable to WRI with respect to the Gas
          Business and/or the Transferred Subsidiaries, or (C) assuming the
          consents, approvals, authorizations or permits and filings or
          notifications referred to in Section 4.2(d)(3) are duly and timely
          obtained or made, any judgment, order, decree, statute, law,
          ordinance, rule or regulation applicable to WRI with respect to the
          Gas Business and/or any of the Transferred Subsidiaries or any of
          their respective properties or assets, other than, in the case of
          clause (B) or (C), any such conflicts, violations, defaults, rights or
          Liens, that, individually or in the aggregate, would not have a
          Material Adverse Effect on the Gas Business, materially impair the
          ability of WRI to perform its obligations hereunder or under any
          Ancillary Document to which WRI is a party or prevent the consummation
          of any of the Transactions and the other transactions contemplated
          hereby or thereby.

               (3) Except as set forth in Section 4.2(d)(3) of the ONEOK
          Disclosure Schedule no notice, report, consent, approval, order or

          permit from any Governmental Entity is required by or with respect to

          Subsidiaries or NewCorp in connection with the execution and delivery
          by WRI of this Agreement or any Ancillary Document to which WRI is a
          party, or the consummation by WRI of the Transactions and the other
          transactions contemplated hereby or thereby, as to which the failure
          to obtain or make would have a Material Adverse Effect on the Gas
          Business or prevent or materially burden or materially impair the
          ability of WRI or the Transferred Subsidiaries to consummate the
          transactions contemplated by this Agreement, except for: (A) the
          filing of a premerger notification report by WRI under the HSR Act and

          respect thereto; (B) the filing with the SEC of the Form S-4, such
          reports under Section 13(a) of the Exchange Act and such other

          and regulations thereunder as may be required in connection with this
          Agreement and the Transactions and the other transactions contemplated
          hereby, and the obtaining from the SEC of such orders as may be so
          required; (C) a filing for a determination by the SEC or its Staff in
          the form of an order or a no-action letter that WRI will not be a

          (e) SEC and Other Documents.

               (1) WRI has made available to ONEOK a true and complete copy of
          each Form 10-K and Form 10-Q filed by WRI with the SEC since January
          1, 1994 and prior to the date of this Agreement (the "WRI SEC
          Documents"). As of their respective dates, the WRI SEC Documents as
          they relate to the Gas Business complied in all material respects with
          the requirements of the Securities Act or the Exchange Act, as the
          case may be, and the rules and regulations of the SEC thereunder
          applicable to such WRI SEC Documents, and none of the WRI SEC
          Documents as they relate to the Gas Business contained any untrue
          statement of a material fact or omitted to state a material fact
          required to be stated therein or necessary to make the statements
          therein, in light of the circumstances under which they were made, for
          the applicable periods, not misleading.

               (2) The unaudited consolidated financial information of the Gas
          Business included as Exhibit B hereto for the three years ended
          December 31, 1995 and for the twelve-month period ended September 30,
          1996 (the "Consolidated Financial Information of the Gas Business")
          were prepared, consistent with WRI's past practices, based upon the
          books and records of WRI, and fairly present, in all material
          respects, as they relate to the Assets of the Gas Business, the
          matters indicated therein. Section 4.2(e)(2) of the WRI Disclosure
          Schedule specifies all accounting principles utilized in connection
          with the preparation of the Consolidated Financial Information of the
          Gas Business which are not in conformity with GAAP. Except as
          disclosed in the WRI SEC Documents, there are no agreements,
          arrangements or understandings with respect to the Gas Business
          between WRI or the Transferred Subsidiaries and any party who is at
          the date of this Agreement or was at the time prior to the date hereof
          but after January 1, 1996 an Affiliate of WRI or the Transferred
          Subsidiaries that are required to be disclosed in the WRI SEC
          Documents.

               (3) WRI has delivered to ONEOK a true and correct copy of WRI's
          FERC Form 2 for the years ended December 31, 1995, December 31, 1994,
          and December 31, 1993, required to be filed with the OCC and KCC,
          which includes the appropriate Supplement containing certain financial
          information related to the gas utility business of WRI (the "Financial
          Information Statements"). The Financial Information Statements: (i)
          have been prepared, consistent with WRI's past practices, based upon
          the books and records of WRI (ii) fairly present, in all material
          respects, the matters indicated for the periods indicated therein, in
          conformity with the regulations of the OCC, KCC and the FERC (subject
          to normal recurring adjustments, none of which are material). WRI has
          also delivered to ONEOK the unaudited PP&E Schedules "Intangible
          Personal Property; Regulatory Assets; Miscellaneous Debits," and "Gas
          Pipelines and Plants," in each case relating to the gas utility
          business as of September 30, 1996 (together, the "PP&E Schedules").
          The PP&E Schedules: (i) have been prepared consistent with WRI's past
          practices based on the books and records of WRI, and (ii) fairly
          present, in all material respects, the matters indicated, as of the
          date indicated (subject to normal recurring adjustments, none of which
          are material). The financial records, ledgers and subledgers, account
          books and other accounting records of WRI relating to the Gas Business
          have been maintained in accordance with good business practice and are
          current, complete, accurate and correct, except for normal month end
          adjustments, in all material respects.

<PAGE>   49

               (4) The unaudited financial information of Westar and MCMC
          delivered to ONEOK were prepared consistent with WRI's past practices,
          based upon the books and records of WRI and the Transferred
          Subsidiaries, and fairly present, in all material respects, the
          matters indicated therein. Section 4.2(e)(4) of the WRI Disclosure
          Schedule specifies all accounting principles utilized in connection
          with the preparation of the financial information of Westar and MCMC
          which are not in conformity with GAAP.

          (f) Information Supplied. None of the information supplied or to be
supplied by WRI or NewCorp for inclusion or incorporation by reference in the
Form S-4 will, at the time the Form S-4 becomes effective under the Securities
Act or at the Merger Effective Time, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, and none of the information supplied or to
be supplied by WRI or NewCorp and included or incorporated by reference in the
Proxy Statement will, at the date mailed to the shareholders of ONEOK or at the
time of the meeting of such shareholders to be held in connection with the
Merger or at the Merger Effective Time, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading. If at any time prior to
the Merger Effective Time any event with respect to the Gas Business, or with
respect to other information supplied by WRI or NewCorp for inclusion in the
Proxy Statement or the Form S-4, shall occur which is required to be described
in an amendment of, or a supplement to, the Proxy Statement or the Form S-4,
such event shall be so described, and such amendment or supplement shall be
promptly filed with the SEC.

          (g) Absence of Certain Changes or Events. Except (I) as disclosed in,
or reflected in the financial statements included in, the WRI SEC Documents
and/or Section 4.2(g) of the WRI Disclosure Schedule, (II) as contemplated by
this Agreement, or (III) for transactions effected or actions taken by WRI or
the Transferred Subsidiaries after the date of this Agreement without breaching
the terms hereof in the case of clauses (iii) through (viii) below, since August
31, 1996, the Gas Business has been conducted in the ordinary course of business
consistent with past practice, and since August 31, 1996 there has not been: (i)
any event or events which, individually or in the aggregate have had or would
have a Material Adverse Effect on the Gas Business, (ii) any amendment of any
material term of any outstanding equity security or the respective certificates
of incorporation or bylaws of Westar or MCMC; (iii) any non-cash dividend or
distribution by Westar or MCMC or any repurchase, redemption or other
acquisition by Westar or MCMC of any outstanding shares of capital stock or
other equity securities of, or other ownership interests in, Westar or MCMC or
any Significant Subsidiary of Westar or MCMC; (iv) any material change in any
method of accounting or accounting practice by WRI relating to the Gas Business
and the Transferred Subsidiaries; (v) any increase in the salaries or other
compensation payable to any such officer or employee of WRI relating to the Gas
Business or any of the Transferred Subsidiaries (except for normal increases in
the ordinary course of business consistent with past practice) or any increase
in, or addition to, other benefits to which any such officer or employee may be
entitled (except as required by the terms of plans as in effect on the date of
this Agreement or as required by law), (vi) any Material Adverse Change or
threat of a Material Adverse Change in the relations of WRI relating to the Gas
Business or the Transferred Subsidiaries with, or any loss or, to the knowledge
of WRI, threat of loss of, any of the material suppliers or customers of the Gas

          the terms of any WRI Pension Benefit Plan which covers Continuing
          Employees or Retired Employees (or to any person pursuant to the terms
          thereof) have been timely made or will be timely made in accordance

          several liability or with respect to which assets are being
          transferred from the WRI Benefit Plans to plans established by NewCorp
          pursuant to the Employee Agreement.

                    can be corrected without material liability, and (2) has
                    received a favorable determination letter from the IRS on
                    its qualification or application for such a determination
                    has been made prior to the expiration of the applicable
                    remedial amendment period, and to the knowledge of WRI there
                    are no circumstances existing likely to result in revocation
                    of any such favorable determination letter.

               b.   Each WRI Benefit Plan is and has been operated in compliance
                    with, all applicable laws, rules and regulations governing
                    such plan, including, without limitation, ERISA and the
                    Code, and all filings, disclosures and notices required have
                    been timely made, except for violations that would not have
                    a Material Adverse Effect on NewCorp. All amendments and
                    actions required to bring each of the WRI Benefit Plans into

                    and the Code and other applicable legal requirements have
                    been made or taken except to the extent that such amendments
                    or actions are not required by law to be made or taken until
                    a date after the Merger Effective Time and except for
                    actions the failure of which to take would not have a
                    Material Adverse Effect on NewCorp.

               c.   To the knowledge of WRI, no individual or entity has engaged
                    in any transaction in connection with which WRI or any WRI
                    Affiliate, or any WRI Benefit Plan or any trust, trustee or
                    administrator thereof, could be subject to liability
                    pursuant to Section 409 or Section 502 of ERISA, or subject
                    to an excise tax pursuant to Section 4975 of the Code, which
                    could in either case have a Material Adverse Effect on
                    NewCorp.

               d.   Except for matters that would not have a Material Adverse
                    Effect on NewCorp:

                    1.   To the knowledge of WRI, no WRI Benefit Plan is subject
                         to any ongoing audit, investigation or other
                         administrative proceeding of the IRS, the Department of
                         Labor or any other Governmental Entity or, to the
                         knowledge of WRI, is scheduled to be subject to such an
                         audit, investigation or proceeding; and

                    2.   No WRI Benefit Plan is the subject of any pending
                         application for administrative relief under any
                         voluntary compliance program of any Governmental Entity
                         (including, without limitation, the IRS' Voluntary
                         Compliance Resolution Program or Walk-in Closing
                         Agreement Program, or the Department of Labor's
                         Delinquent Filer Voluntary Compliance Program).


               (4) Pension Benefit Plan; Liabilities. Except as disclosed in
          Section 4.2(m)(4) of the WRI Disclosure Schedule, with respect to the
          WRI Pension Benefit Plans, individually and in the aggregate, no
          termination or partial termination of any WRI Pension Benefit Plan has
          occurred and no event has occurred that would be reasonably expected
          to subject the Gas Business or NewCorp, by reason of joint and several
          liability, to any liability arising under the Code, ERISA or any other
          applicable law (including, without limitation, any liability to or
          under any such plan or to the PBGC, or under any indemnity agreement
          to which WRI or any WRI Affiliate is a party), which liability could
          have a Material Adverse Effect on the Gas Business or NewCorp, by
          reason of joint and several liability (excluding liability for benefit
          claims and funding obligations payable in the ordinary course and
          liability for PBGC insurance premiums payable in the ordinary course).

               (5) Welfare Plans. To the knowledge of WRI, no circumstances
          exist that could subject WRI or any WRI Affiliate to an excise tax
          under Section 4976 of the Code that would have a Material Adverse
          Effect on the Gas Business or NewCorp by reason of joint and several
          liability.

          will make available to ONEOK upon request, a true and correct copy of
          each collective bargaining agreement to which WRI or any WRI Affiliate
          is a party or under which WRI has obligations relating to the Gas
          Business or to NewCorp by reason of joint and several liability; and,
          with respect to each such WRI Benefit Plan relating to the Gas
          Business or to NewCorp by reason of joint and several liability, WRI
          has made available or will make available upon request to ONEOK a true

          contemplated by this Agreement will not directly or indirectly (either
          alone or upon the occurrence of any additional or further acts or

               (1) WRI with respect to the Gas Business and the Transferred
          Subsidiaries, individually or together, have good and sufficient title
          to all of the Assets that they purport to own, including all of the
          properties and assets reflected in the balance sheet as of September
          30, 1996, included in the Consolidated Financial Information of the
          Gas Business and all properties and assets purchased or otherwise
          acquired since September 30, 1996. Such assets are sufficient to
          enable WRI with respect to the Gas Business and the Transferred
          Subsidiaries to conduct the Gas Business as currently conducted
          without material interference, and, at the Closing, will be free and
          clear of Liens, other than Permitted Liens. WRI, with respect to the
          Gas Business, and the Transferred Subsidiaries, individually or

          of such properties under such leases, other than any properties as to
          which such leases will have terminated in the ordinary course of
          business since the date of such financial information. Neither WRI,
          with respect to the Gas Business, nor any of the Transferred
          Subsidiaries, nor any of their predecessors has received any written
          notice of any adverse claim to the title to any properties owned by
          them or with respect to any lease under which any properties are held
          by them, other than any claims that, individually or in the aggregate,
          would not have a Material Adverse Effect on the Gas Business.

          Transferred Subsidiaries is in violation of the terms of any Easement
          except any such violations that, individually or in the aggregate,
          would not have a Material Adverse Effect on the Gas Business. Except
          as would not have a Material Adverse Effect on the Gas Business, all
          Easements in favor of the Gas Business are valid and enforceable and
          grant the rights purported to be granted thereby and all rights
          necessary thereunder for the operation of the Gas Business. Except as
          would not have a Material Adverse Effect on the Gas Business, to the
          knowledge of WRI, there are no spatial gaps in the Easements in favor
          of the Gas Business that would have a Material Adverse Effect on the
          Gas Business and all parts of the pipeline assets which constitute a
          portion of the Assets are located either on property which is owned in
          fee by WRI or the Transferred Subsidiaries or on property which is
          subject to an Easement in favor of WRI or a Transferred Subsidiary.

          (v) Condition of Assets. To the knowledge of WRI and the Transferred
Subsidiaries, the buildings, plants, structures, and equipment of WRI relating
to the Gas Business and the Transferred Subsidiaries are structurally sound, are
in good operating condition and repair, and are adequate for the uses to which
they are being put, and none of such buildings, plants, structures, or equipment
is in need of maintenance or repairs except for ordinary, routine maintenance
and repairs that are not material in nature or cost.

          (w) Accounts Receivable. All Accounts Receivable with respect to the
Gas Business represent or will represent, as of the Closing, valid obligations
arising from sales actually made or services actually performed in the ordinary
course of business of WRI with respect Gas Business and of the Transferred
Subsidiaries. Unless paid prior to the Closing, the Accounts Receivable relating
to the Gas Business are or will be, as of the Closing, collectible, subject only
to allowance for doubtful accounts, and calculated consistently with past
practice. There is no contest, claim or right of set-off, under any contract or
with any obligor of an Account Receivable relating to the Gas Business relating
to the amount or validity of such Account Receivable which would have a Material
Adverse Effect on the Gas Business.

          (x) Beneficial Ownership of ONEOK Common Stock. Neither WRI nor any of
its Subsidiaries "beneficially owns" (as defined in Rule 13d-3 under the
Exchange Act) any of the outstanding ONEOK Common Stock or ONEOK Preferred
Stock.

          (y) Brokers. Except for the fees and expenses payable to Salomon,
which fees are reflected in its agreement with WRI and will be for the account
of and paid by WRI and not by NewCorp, no broker, investment banker or other
person is entitled to any broker's, finder's or other similar fee or commission
in connection with the negotiations leading to this Agreement or the
consummation of the Transactions and the other transactions contemplated by this
Agreement based upon arrangements made by or on behalf of WRI or any of the
Transferred Subsidiaries.

          (z) Insurance. With respect to the Gas Business, WRI and the
Transferred Subsidiaries maintain insurance coverage as is customary for the
industry in which the Gas Business operates (taking into account the cost and
availability of such insurance). All such insurance policies are with reputable
insurance carriers. There are no claims pending under any of such policies as to
which coverage has been questioned, denied or disputed by the underwriters of
such policies or in respect of which such underwriters have reserved their
rights, except for claims that would not have a Material Adverse Effect on the
Gas Business. All premiums payable under all such policies have been paid and
WRI and the Transferred Subsidiaries have otherwise complied fully with the
terms and conditions of all such policies.

of the Transferred Subsidiaries to WRI and its Subsidiaries shall have been

the foregoing persons, on the other hand, except as set forth in Section 4.2(ac)
of the WRI Disclosure Schedule.

Subsidiaries to) afford to the officers, employees, accountants, counsel and
other representatives of the other, access, during normal business hours during

the date upon which the Form S-4 becomes effective as ONEOK and WRI shall
mutually determine.

promulgated thereunder with respect to the Transactions and the other
transactions contemplated hereby and by the Ancillary Documents. Such parties
will use all commercially reasonable efforts to make such filing promptly and to
respond on a timely basis to any requests for additional information made by
either of such agencies.

          (b) Other Regulatory Approvals. Each party hereto shall cooperate and
use its best efforts to promptly prepare and file all necessary documentation,
to effect all necessary applications, notices, petitions, filings and other
documents, and to use all commercially reasonable efforts to obtain (and will
cooperate with each other in obtaining) any consent, acquiescence,
authorization, order or approval of, or any exemption or nonopposition by, any
Governmental Entity required to be obtained or made by ONEOK, WRI or any of
their respective Subsidiaries in connection with the Transactions and the other
transactions contemplated by the Ancillary Documents and hereby or the taking of
any action contemplated thereby or by this Agreement, including without
limitation the ONEOK Required approvals and the WRI Required Approvals. Each
party shall have the right to review and approve in advance (such approvals not
to be unreasonably withheld based upon the economic benefits expected to be
realized by such party from the Transactions and the other transactions
contemplated by the Ancillary Documents and this Agreement) all applications for
approvals to be filed by the other party. Each party shall consult with the
other with respect to the obtaining of all such necessary or advisable permits,
consents, approvals and authorizations of Governmental Authorities.

          (c) Other Approvals. Each party hereto will, and will cause its
Subsidiaries to, take all commercially reasonable actions necessary to obtain
(and will cooperate with each other in obtaining) all ONEOK Required Consents
and all WRI Required Consents, as the case may be.

          6.7 Authorization for Shares and Stock Exchange Listing. Prior to the
Merger Effective Time, WRI shall have caused NewCorp to take all action
necessary to permit it to issue the number of shares of NewCorp Common Stock
required to be issued pursuant to Sections 3.1 and 3.2. Prior to the Closing
Date, WRI shall cause NewCorp to take all reasonable efforts to cause the shares
of NewCorp Common Stock and NewCorp Preferred Stock to be issued in the Merger
and the shares of NewCorp Common Stock to be reserved for issuance upon exercise
of the ONEOK Options assumed by NewCorp pursuant to Section 6.8 and issuances
under the ONEOK Stock Plans to be approved for listing on the NYSE, subject to
official notice of issuance.

          6.8 Stock Options. (a) At the Merger Effective Time, each outstanding
ONEOK Option, whether vested or unvested, shall be assumed by NewCorp. Each such
option shall be deemed to constitute an option to acquire, on the same terms and
conditions as were applicable under each ONEOK Option, a number of shares of
NewCorp Common Stock equal to the number of shares of ONEOK Common Stock as the
holder of such ONEOK Option would have been entitled to receive pursuant to the
Merger had such holder exercised such option in full immediately prior to the
Merger Effective Time, at a price per share equal to (y) the aggregate exercise
price for ONEOK Common Stock otherwise purchasable pursuant to such ONEOK
Option, divided by (z) the number of full shares of NewCorp Common Stock deemed
purchasable pursuant to such ONEOK Option. In no event shall NewCorp be required
to issue fractional shares of NewCorp Common Stock. In the case of any option
which is an "incentive stock option" (as defined in Section 422 of the Code),
the adjustments made pursuant to this subsection shall be and are intended to be
effected in a manner which is consistent with the requirements of Section 424(a)
of the Code.



                                       61
<PAGE>   73

          (b) As soon as practicable after the Merger Effective Time, NewCorp
shall file with the SEC a registration statement on Form S-8 (or any successor
form) or another appropriate form with respect to the shares of NewCorp Common
Stock subject to the ONEOK Options assumed in accordance with this Section 6.8
and shall use all commercially reasonable efforts to maintain the effectiveness
of such registration statement or registration statements (and maintain the
current status of the prospectus or prospectuses contained therein) for so long
as the ONEOK Options remain outstanding.

          6.9 Agreement to Defend. In the event any claim, action, suit,
investigation or other proceeding by any governmental body or other person or
other legal or administrative proceeding is commenced that questions the
validity or legality of the Transactions and the other transactions contemplated
hereby and by the Ancillary Documents or seeks damages in connection therewith,
the parties hereto agree to cooperate and use their reasonable efforts to defend
against and respond thereto.

          6.10 Public Announcements. WRI and ONEOK will consult with each other
before issuing any press release or otherwise making any public statements with
respect to the Transactions and the other transactions contemplated by this
Agreement and the Ancillary Documents, and shall not issue any such press
release or make any such public statement prior to such consultation, except as
may be required by applicable law or by obligations pursuant to any listing
agreement with any national securities exchange or transaction reporting system.

          6.11 Other Actions. Except as contemplated by this Agreement, neither
WRI nor ONEOK shall, and none of them shall permit any of their respective
Subsidiaries to, take or agree or commit to take any action that is reasonably
likely to result in any of its respective representations or warranties
hereunder being untrue in any material respect or in any of the conditions to
the Merger set forth in Article VII not being satisfied, in each case as of the
Closing Date.

          6.12 Advice of Changes; SEC Filings. WRI and ONEOK shall confer on a
regular basis with each other, report on operational matters and promptly advise
each other orally and in writing of any change or event having, or which,
insofar as can reasonably be foreseen, could have, a Material Adverse Effect on
the Gas Business or ONEOK, as the case may be. ONEOK and WRI shall promptly
provide each other (or their respective counsel) copies of all filings made by
such party with the SEC or any other Governmental Entity in connection with this
Agreement and the Transactions and the other transactions contemplated hereby
and by the Ancillary Documents.

          6.13 Reorganization. It is the intention of the parties hereto that
the Merger will qualify as a reorganization described in Section 368(a) of the
Code (and any comparable provisions of applicable state law) and the Asset
Transaction will qualify as a transfer described in Section 351 of the Code (and
any comparable provisions of applicable state law) and the parties will so
characterize the Merger and the Asset Transaction for the purpose of all Returns
and other filings. None of WRI, ONEOK nor NewCorp (nor any of their respective
Subsidiaries) will take or omit to take any action (whether before, on or after
the Closing Date) that would cause the Merger or the Asset Transaction not to be
so treated.



                                       62
<PAGE>   74

          6.14 Disclosure Schedules. The ONEOK Disclosure Schedule and the WRI
Disclosure Schedule (collectively, the "Disclosure Schedules") are an integral
part of this Agreement and shall modify or otherwise affect the respective
warranties, covenants or agreements of the parties hereto contained in this
Agreement.

          6.15 Preparation and Filing of Returns; Payment of Taxes. (a) WRI
shall include Westar and MCMC for all taxable periods of Westar and MCMC ending
on or before the Closing Date in any consolidated, combined or unitary Income
Tax Returns for which they are eligible to do so. WRI shall cause to be timely
prepared and filed all such consolidated, combined or unitary Returns. NewCorp
agrees to cooperate with WRI and its Affiliates in the preparation of the
portions of such Returns pertaining to Westar and MCMC. For purposes of this
Section 6.15(a), WRI shall treat (and shall cause Westar and MCMC to treat) the
Closing Date as the last date of the taxable period of Westar and MCMC in which
they shall be included in such Returns. WRI shall cause to be timely paid all
Taxes to which such Returns relate for all periods covered by such Returns.

          (b) WRI shall cause to be timely prepared and filed all required
Income Tax Returns of Westar and MCMC (other than those to be filed by WRI
pursuant to paragraph (a) of this Section 6.15) for any period which ends on or
before the Closing Date for which Income Tax Returns have not been filed as of
the Closing Date. WRI shall pay all Taxes to which such Returns relate for all
periods covered by such Returns (after taking into account any estimated Taxes
paid prior to the Closing).

          (c) NewCorp shall cause to be timely prepared and filed, subject to
review by WRI, all required Income Tax Returns of NewCorp, Westar and MCMC for
any period which begins before and ends after the Closing Date (a "Straddle
Period") and shall cause to be paid all Taxes with respect to the Returns to be
caused to be filed by NewCorp pursuant to this Section 6.15(c). Such Taxes to be
caused to be paid by NewCorp, to the extent attributable to the portion of a
Straddle Period ending on the Closing Date, shall be referred to herein as
"Pre-Closing Straddle Period Income Taxes." Except to the extent taken into
account as a Current Liability in the calculation of the Closing Working
Capital, WRI shall pay to NewCorp an amount equal to the Pre-Closing Straddle
Period Income Taxes due with respect to any such Returns caused to be filed by
NewCorp (after taking into account any estimated Taxes paid prior to the
Closing). Such Pre-Closing Straddle Period Income Taxes shall be calculated as
though the taxable year of NewCorp, Westar and MCMC terminated at the close of
business on the Closing Date; provided, however, that, in the case of a
franchise Tax not based on income, sales, receipts, or other transactions,
Pre-Closing Straddle Period Income Taxes shall be equal to the amount of
franchise Tax for the taxable year which would have been imposed if such Tax
were determined based on the assets and liabilities of NewCorp, Westar and MCMC
(as applicable) as of the Closing, multiplied by a fraction, the numerator of
which shall be the number of days from the beginning of the taxable year through
the Closing Date and the denominator of which shall be the number of days in the
taxable year. Any amounts owed by WRI to NewCorp pursuant to this Section
6.15(c) shall be paid by WRI within five days of NewCorp's request therefor or
five days prior to the date on which NewCorp is required to cause to be paid the
related Tax liability, whichever is later.



                                       63
<PAGE>   75

          (d) To the extent permitted by applicable Law, all Returns prepared
pursuant to this Section 6.15 shall be prepared in all material respects, and
all elections with respect to such Returns shall be made, consistent with prior
practice with respect to Westar and MCMC, except as may be mutually agreed by
NewCorp and WRI.

          (e) NewCorp shall, with the assistance of WRI, prepare and file or
cause to be prepared and filed all Returns with respect to Taxes described in
Section 1.8.

          6.16 Access to Information. From and after the Closing:

          (a) WRI and each of its Affiliates shall grant to the Surviving
Corporation (or its designees) access at all reasonable times to all of the
information, books and records relating to the Surviving Corporation and its
Subsidiaries within the possession of WRI or any of its Affiliates (including
work papers and correspondence with taxing authorities), shall afford to the
Surviving Corporation (or its designees) the right (at the Surviving
Corporation's expense) to take extracts therefrom and to make copies thereof,
and shall render other reasonable assistance, to the extent reasonably necessary
to permit the Surviving Corporation or any of its Affiliates (or its designees)
to prepare Returns, to conduct negotiations with Tax authorities, to fulfill an
obligation to any Governmental Authority imposed by law, regulation or order and
to implement the provisions of, or to investigate or defend any claims between
the parties arising under, this Agreement.

          (b) The Surviving Corporation shall grant or cause its Subsidiaries to
grant to WRI or any of its Affiliates (or its designees) access at all
reasonable times to all of the information, books and records relating to the
Gas Business within the possession of the Surviving Corporation, or its
Subsidiaries (including work papers and correspondence with taxing authorities),
shall afford to WRI (or its designees) the right (at WRI's expense) to take
extracts therefrom and to make copies thereof, and shall render other reasonable
assistance, to the extent reasonably necessary to permit WRI (or its designees)
to prepare Returns, to conduct negotiations with Tax authorities, to fulfill an
obligation to any Governmental Authority imposed by law, regulation or order and
to implement the provisions of, or to investigate or defend any claims between
the parties arising under, this Agreement or otherwise.

          (c) Each of the parties hereto will preserve and retain all schedules,
work papers and other documents relating to any Returns of or with respect to
the Gas Business or to any claims, audits or other proceedings affecting the Gas
Business until the expiration of the statute of limitations (including
extensions) applicable to the taxable period to which such documents relate or
until the final determination of any controversy with respect to such taxable
period, and until the final determination of any payments that may be required
with respect to such taxable period under this Agreement.

<PAGE>   76

          (d) Notwithstanding the foregoing provisions of this Section, neither
the Surviving Corporation nor WRI shall be required to grant or cause to be
granted to the other access to information, books and records or to furnish
extracts or copies thereof if such information, books and records also include
information regarding such party or any of its Affiliates unrelated to the Gas
Business. In such circumstances, such party shall either (i) provide
appropriately detailed summaries of the information contained therein, or (ii)
in providing extracts or copies thereof, redact the information relating to such
party or its Affiliates unrelated to the Gas Business.

          (e) The information received by a party pursuant to this Section shall
be treated as if it were "Evaluation Material," and the receiving party
hereunder were the receiving party, under the Confidentiality Agreement.

          6.17 Non-Competition. (a) In order to induce ONEOK to enter into this
Agreement, WRI covenants and agrees that from the Closing Date until the fifth
(5th) anniversary of the Closing Date, it shall not, and shall not permit any of
its Subsidiaries to, directly or indirectly,

               (i) own, manage, operate, join, control, finance or participate
          in the ownership, management, operation, control or financing, of, or
          be connected as a partner, principal, agent, representative,
          consultant or otherwise with, or use or permit its name to be used in
          connection with, any local natural gas distribution business or
          enterprise in the States of Kansas, Oklahoma, or Missouri; or

               (ii) solicit any contracts or business relationships involving
          local natural gas distribution in the States of Kansas, Oklahoma, or
          Missouri.

          Notwithstanding the foregoing, nothing in this Section 6.17 shall
prohibit WRI or its Subsidiaries from: (A) acquiring and retaining any entity
which engages (at the time of such acquisition or thereafter) in one or more
business(es) which compete(s) with the Surviving Corporation in the business of
local natural gas distribution in the States of Kansas, Oklahoma and/or
Missouri, provided that the assets of such competing business(es) do not
constitute more than 20% of the consolidated assets of such acquired entity at
the time of such acquisition (or thereafter, during the term of this Agreement);
or (B) acquiring, in the aggregate, "beneficial ownership" (as defined under the
Exchange Act) of not more than 20% of any class of publicly-traded equity
securities or any profit or loss interest in any publicly-held entity which
competes with the Surviving Corporation in the business of local natural gas
distribution, in the States of Kansas, Oklahoma and/or Missouri. 

          (b) If any part of the restrictions set forth in Section 6.17(a)
should, for any reason whatsoever, be declared invalid by a court of competent
jurisdiction, the validity or enforceability of the remainder of such
restriction shall not thereby be adversely affected and shall be enforced to the
full extent permitted by law. If any of such restrictions are deemed to be
unreasonable by a court of competent jurisdiction, then WRI shall submit to the
reduction or modification thereof as said court deems reasonable.



                                       65
<PAGE>   77

          (c) The parties hereto agree that irreparable damage would occur in
the event that any of the provisions of this were not performed in accordance
with its specific terms or were otherwise breached. It is accordingly agreed
that the parties shall be entitled to an injunction or injunctions to prevent
breaches of this Section 6.17, Section 6.18 or Section 6.20 and to enforce
specifically the terms and provisions hereof in any court of the United States
or any state having jurisdiction, this being in addition to any other remedy to
which they are entitled at law or in equity.

          6.18 Use of Name. From and after the Closing, neither WRI nor any of
its Subsidiaries shall use the name "Mid Continent Market Center," or any
similar name.

          6.19 Standstill. WRI agrees that, for the period from the date hereof
through the Closing, except as expressly contemplated by the Asset Transaction
or as permitted by this Agreement, including without limitation Section 5.2(b)
hereof, it shall not, and shall not permit any of its Subsidiaries to, (a) in
any manner acquire, agree to acquire or make any proposal to acquire, directly
or indirectly, any securities or property of ONEOK or any of its Subsidiaries,
(b) except at the specific written request of ONEOK, propose to enter into,
directly or indirectly, any merger or business combination involving ONEOK or
any of its Subsidiaries or to purchase, directly or indirectly, a material
portion of the assets of ONEOK or any of its Subsidiaries, (c) make, or in any
way participate, directly or indirectly, in any "solicitation" or "proxies" (as
such terms are used in the proxy rules of the SEC) to vote, or seek to advise or
influence any person with respect to the voting of, any voting securities of
ONEOK or any of its Subsidiaries, (d) form, join or in any way participate in a
"group" (within the meaning of Section 13(d)(3) of the Exchange Act) with
respect to any voting security of ONEOK or any of its Subsidiaries, (e)
otherwise act, alone or in concert with others, to seek to control or influence
the management, Board of Directors or policies of ONEOK, (f) disclose any
intention, plan or arrangement inconsistent with the foregoing or (g) advise,
assist or encourage any other persons in connection with any of the foregoing.
WRI also agrees during such period not to (i) request ONEOK (or its directors,
officers, employees or agents), directly or indirectly, to amend or waive any
provision of this Section 6.19 (including this sentence), or (ii) take any
action which might require ONEOK to make a public announcement regarding the
possibility of a business combination or merger.

          6.20 Further Assurances. Subject to the terms and conditions of this
Agreement, each of ONEOK and WRI shall use all reasonable efforts to take, or
cause to be taken, all action and to do, or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the Transactions and the other transactions
contemplated by this Agreement, including the satisfaction of the conditions
specified in Article VII of this Agreement. In case at any time after the Merger
Effective Time any further action is necessary or desirable to carry out the
purposes of this Agreement, the proper officers and directors of each party to
this Agreement shall take all necessary actions to the extent not inconsistent
with their other duties and obligations or applicable law.



                                       66
<PAGE>   78

          6.21 Insurance. To the extent reasonably requested by the Surviving
Corporation, at the direction and expense of the Surviving Corporation, WRI will
assist the Surviving Corporation in pursuing any claims under insurance policies
relating to the Gas Business and enforcing any claims or rights under such
policies.

          6.22 Schedules. (a) Notwithstanding anything to the contrary in this
Agreement, the parties hereto acknowledge and agree that the Schedules hereto
and the Schedules to the Exhibits hereto will be delivered and attached to this
Agreement and to the applicable Exhibits within 30 days after the date hereof.
In addition, the parties hereto may from time to time within such 30-day period,
update Schedules to this Agreement and to the Exhibits hereto delivered on the
date hereof. Upon the delivery of such Schedules and such updates to the parties
hereto, such Schedules and such updates shall be deemed the Schedules of this
Agreement and of the Exhibits hereto for all purposes of this Agreement.

          (b) Notwithstanding anything to the contrary in this Agreement, to the
extent any representation or warranty specified in this Agreement refers to, or
is modified by, a Schedule which is to be delivered after the date hereof
pursuant to Section 6.22(a), such representation and warranty shall be deemed
made, and first made, as of the date of the delivery of the applicable Schedules
pursuant to Section 6.22(a) (it being understood and agreed that any
representation or warranty, or any portion of any representation or warranty,
which does not refer to, or is not modified by, such Schedules shall be deemed
made as of the date hereof).

                                   ARTICLE VII
                              CONDITIONS PRECEDENT

          7.1 Conditions to Each Party's Obligation to Effect the Transactions.

other transactions contemplated hereby and by the Ancillary Documents shall be
subject to satisfaction prior to the Closing Date of the following conditions:

          (c) Other Approvals. The waiting period applicable to the consummation
of the Transactions and the other transactions contemplated by the Transfer
Documents, this Agreement and the Ancillary Documents shall have expired or been
terminated and all filings required to be made prior to the relevant Merger
Effective Time with, and all consents, approvals, permits and authorizations
required to be obtained prior to the relevant Merger Effective Time from, any
Governmental Entity in connection with the execution and delivery of this
Agreement and the consummation of the Transactions and the other transactions
contemplated hereby and by the Ancillary Documents by ONEOK, WRI and NewCorp
shall have been made or obtained (as the case may be), except for such consents,
approvals, permits and authorizations the failure of which to be obtained would
not, in the aggregate, be reasonably likely to result in a Material Adverse
Effect on ONEOK or the Gas Business or to materially adversely affect the
consummation of the Transactions and the other transactions contemplated hereby
and by the Ancillary Documents or the economic and strategic benefits to be
achieved by the party invoking these conditions, and no such consent, approval,
permit or authorization shall impose terms or conditions that would have, or
would be reasonably likely to have, a Material Adverse Effect on ONEOK or the
Gas Business.



                                       67
<PAGE>   79

          (d) Form S-4. The Form S-4 shall have become effective under the
Securities Act and shall not be the subject of any stop order or proceedings
seeking a stop order.

          (e) No Injunctions or Restraints. No temporary restraining order,
preliminary or permanent injunction or other order issued by any court of
competent jurisdiction, no order of any Governmental Entity having jurisdiction
over ONEOK, WRI or the Gas Business, and no other legal restraint or prohibition
shall be in effect (an "Injunction") preventing or making illegal the
consummation of the Transactions or the other transactions contemplated hereby
and by the Ancillary Documents; provided, however, that prior to any party
invoking this condition, such party shall have complied fully with its
obligations under Sections 6.6 and 6.20.

          (f) Other Agreements. WRI and ONEOK shall have entered into a Shared
Services Agreement (the "Shared Services Agreement") relating to functions and
services where synergies can be achieved between the parties to avoid
unnecessary duplication of expenses and a Marketing Agreement (the "Marketing
Agreement") in form, scope and substance reasonably satisfactory to WRI and
ONEOK.

          (g) The Shareholder Agreement shall be executed and delivered by the
parties thereto.

          (h) Schedules. On the date of the delivery of the Schedules to this
Agreement pursuant to Section 6.22(a), such Schedules shall be reasonably
satisfactory to WRI and ONEOK; provided, however, that any matters disclosed in
the ONEOK SEC Documents or the WRI SEC Documents shall be deemed reasonably
satisfactory, and the Schedules or updates thereto delivered by each party shall
be deemed reasonably satisfactory to the other party unless the Schedules or
updates thereto delivered by a party hereto disclose matters which, in the
aggregate, are materially inconsistent with the other party's good faith
expectation on the date hereof with regard to the business, operations and
prospects of ONEOK or the Gas Business, as applicable.

          (i) 1935 Act. Receipt of and order of the SEC under Section 9(a)(2) of

Section 2(a)(8) of the 1935 Act for the purposes of the 1935 Act as a result of
the Merger, in each case, not materially impairing the economic and strategic
benefits of the Transactions and the other transactions contemplated by this
Agreement to WRI or ONEOK.



                                       68
<PAGE>   80

          7.2 Conditions of Obligations of WRI. The obligations of WRI to
consummate the Transactions and the other transactions contemplated hereby and
by the Ancillary Documents is subject to the of the following conditions, any or
all of which may be waived in whole or in part by WRI.

          (a) Representations and Warranties. Each of the representations and
warranties of ONEOK set forth in this Agreement shall be true and correct in all
material respects as of the date of this Agreement or the date of delivery of
the Schedules or updates thereto and (except to the extent such representations
and warranties speak as of an earlier date) as of the Closing Date as though
made on and as of the Closing Date, except where the failure to be so true and
correct (without giving effect to the individual materiality qualifications and
thresholds otherwise contained in Section 4.1 hereof) could not reasonably be
expected to have a Material Adverse Effect on ONEOK or as otherwise contemplated
by this Agreement, and WRI shall have received a certificate signed by the Chief
Executive Officer and the Chief Financial Officer of ONEOK to such effect.

          (b) Performance of Obligations of ONEOK. ONEOK shall have performed in
all material respects all obligations required to be performed by it under this
Agreement at or prior to the Closing Date, and WRI shall have received a
certificate signed on behalf of ONEOK by the Chief Executive Officer and the
Chief Financial Officer of ONEOK to such effect.

          (c) Tax Opinion. WRI shall have received (x) either (i) an opinion of
Sullivan & Cromwell, counsel to WRI, in form and substance reasonably
satisfactory to WRI, dated the Closing Date, or (ii) a private letter ruling
from the IRS, in each case to the effect that, if the Asset Transaction is
consummated in accordance with the terms of this Agreement the Asset Transaction
will be treated for federal Income Tax purposes as a transfer described in
Section 351 of the Code and (y) the opinion of Fried, Frank, Harris, Shriver &
Jacobson delivered to ONEOK pursuant to Section 7.3(c), to the effect that, if
the Merger is consummated in accordance with the terms of this Agreement, the
Merger will be treated for federal Income Tax purposes as a reorganization
within the meaning of Section 368(a) of the Code. In rendering such opinion,
Sullivan & Cromwell may receive and rely upon appropriate representations of
fact, including facts contained in certificates of WRI and ONEOK, which
representations are in form and substance reasonably satisfactory to such
counsel.

          (d) Required Consents. The ONEOK Required Consents and the WRI
Required Consents shall have been obtained, except for such ONEOK Required
Consents or WRI Required Consents the failure of which to be obtained would not
have a Material Adverse Effect on ONEOK or WRI, as the case may be.

          (e) KCC Order. The KCC Order shall be in such form and substance and
shall cover such matters as shall be reasonably satisfactory to WRI.



                                       69
<PAGE>   81

          (f) Pooling of Interests. WRI shall have received a letter from Arthur
Andersen, L.L.P., its independent public accountants (based on consultation with
the office of the Chief Accountant of the SEC) stating that, as a result of the
consummation of the Transactions and the other transactions contemplated by this
Agreement, WRI shall not be precluded from accounting for any potential business
combination between WRI and Kansas City Power & Light Company as a "pooling of
interests" as defined by Accounting Principles Bulletin No. 16 (APB 16)
regarding Accounting for Business Combinations and SEC or SEC Staff
interpretations thereunder.

          (g) OCC Order. The OCC Order shall be in such form and substance and
shall cover such matters as shall be reasonably satisfactory to WRI.

effect the Transactions and the other transactions contemplated hereby and by
the Ancillary Documents is subject to the satisfaction of the following
conditions, any or all of which may be waived in whole or in part by ONEOK:

warranties of WRI set forth in this Agreement shall be true and correct in all
material respects as of the date of this Agreement or the date of delivery of
the Schedules or updates thereto (except to the extent such representations and
warranties speak as of an earlier date) and as of the Closing Date as though
made on and as of the Closing Date, except where the failure to be so true and
correct (without giving effect to the individual materiality qualifications and
thresholds otherwise contained in Section 4.2 hereof) could not reasonably be
expected to have a Material Adverse Effect on the Gas Business or as otherwise
contemplated by this Agreement, and ONEOK shall have received a certificate
signed by the Chief Executive Officer and the Chief Financial Officer of WRI to
such effect.

          (b) Performance of Obligations and WRI. WRI shall have performed in

          (c) Tax Opinion. ONEOK shall have received (x) an opinion of Fried,

reasonably satisfactory to ONEOK, dated the Closing Date, to the effect that, if
the Merger is consummated in accordance with the terms of this Agreement, the
Merger will be treated for federal Income Tax purposes as a reorganization
within the meaning of Section 368(a) of the Code and (y) either (i) the opinion
of Sullivan & Cromwell delivered to WRI pursuant to Section 7.2(c) or (ii) a
private letter ruling from the IRS, in each case to the effect that, if the

transfer described in Section 351 of the Code, a copy of each of which will be
furnished to Donald A. Kihle of Arrington Kihle Gaberino & Dunn, counsel to
ONEOK. In rendering such opinion, Fried, Frank, Harris, Shriver & Jacobson may
receive and rely upon appropriate representations of fact, including facts
contained in certificates of NewCorp, WRI and ONEOK and certain stockholders and
members of management of ONEOK and NewCorp, which representations are in form
and substance reasonably satisfactory to such counsel.

          (d) Required Consents. The WRI Required Consents and the ONEOK
Required Consents shall have been obtained, except for such WRI Required
Consents or ONEOK Required Consents the failure of which to be obtained would
not have a Material Adverse Effect on the Gas Business or ONEOK, as the case may
be.

          (e) Asset Transaction. The Asset Transaction shall have been
consummated pursuant to this Agreement, the Ancillary Documents and the other
Transfer Documents in form and substance reasonably satisfactory to ONEOK.

cover such matters as shall be reasonably satisfactory to ONEOK.

          9.2 Effect of Termination.

          (a) In the event of termination of this Agreement by any party hereto
as provided in Section 9.1, this Agreement shall forthwith become void and there
shall be no liability or obligation on the part of WRI or ONEOK except (i) with
respect to this Section 9.2, the second and third sentences of Section 6.4,
Section 9.3 and Article X, and (ii) a party shall be liable to the extent that
such termination results from the willful breach by such party hereto of any of
its representations or warranties or of any of its covenants or agreements
contained in this Agreement.

          (b) If WRI or ONEOK terminates this Agreement pursuant to Section
9.1(b)(ii) and, at the time of the ONEOK Stockholders' Meeting, there shall be
outstanding and publicly announced, an Acquisition Proposal, ONEOK shall, within
3 days after WRI delivers to ONEOK the Expense Reimbursement Letter (as such
term is herein defined), reimburse WRI for all expenses incurred by WRI and its
Subsidiaries in connection with the Transactions and the other transactions
contemplated hereby and by the Ancillary Documents, up to $1,500,000, as
specified in writing by WRI to ONEOK (such writing shall be referred to herein
as the "Expense Reimbursement Letter"), by a payment in cash by wire transfer of
immediately available funds to an account designated by WRI (the "Reimbursed
Expenses"). In addition, upon the consummation of an Acquisition Proposal which
was entered into within 12 months after termination of the Agreement pursuant to
Section 9.1(b), whereby ONEOK shall be obligated to reimburse WRI for expenses
pursuant to this Section 9.2(b), ONEOK shall pay WRI, by a payment in cash by
wire transfer of immediately available funds to an account designated by WRI, an
amount equal to $20,000,000 less the amount of the Reimbursed Expenses.

          (c) If WRI terminates this Agreement as a result of the failure to be
satisfied of the condition specified in Section 7.2(e) or, if ONEOK terminates
this Agreement as a result of the failure to be satisfied of the condition
specified in Section 7.3(f), then the terminating party shall promptly reimburse
the non-terminating party for expenses reasonably incurred by the
non-terminating party in connection with this Agreement in an amount not to
exceed $1,500,000.

          9.3 Expenses. The parties agree that the agreements contained in
Section 9.2 are an integral part of the Transactions and the other the
transactions contemplated by this Agreement and by the Ancillary Documents and
represent liquidated damages and are not a penalty. Notwithstanding anything to
the contrary contained in Section 9.2, if one party fails to promptly pay to the
other any fee due under Section 9.2, in addition to any amounts paid or payable
pursuant to such Section, the defaulting party shall pay the costs and expenses
(including legal fees and expenses) in connection with any action, including the
filing of any lawsuit or other legal action, taken to collect payment, together
with interest on the amount of any unpaid fee at the publicly announced prime
interest rate of Citibank, N.A. from the date such fee was required to be paid.
Except as otherwise provided in this Agreement, ONEOK shall pay its fees and
expenses, and WRI shall pay its fees and expenses and the fees and expenses of
NewCorp, incurred in connection with the Transactions and the other transactions
contemplated hereby and by the Ancillary Documents.

          9.4 Amendment. This Agreement may be amended by mutual agreement of
ONEOK and WRI, by action taken or authorized by their respective Boards of
Directors, at any time prior to the Merger Effective Time. This Agreement may
not be amended except by an instrument in writing signed on behalf of each the
parties hereto.

          9.5 Extension; Waiver. At any time prior to the Merger Effective Time,
the parties hereto, by action taken or authorized by their respective Boards of
Directors, may, to the extent legally allowed: (i) extend the time for the
performance of any of the obligations or other acts of the other parties hereto;
(ii) waive any inaccuracies in the representations and warranties contained
herein or in any document delivered pursuant hereto; and (iii) waive compliance
with any of the agreements or conditions contained herein. Any agreement on the
part of a party hereto to any such extension or waiver shall be valid only if
set forth in a written instrument signed on behalf of such party.

                                    ARTICLE X
                                 INDEMNIFICATION

          10.1 General Indemnification. (a) WRI hereby agrees to indemnify ONEOK
and its Affiliates (including from and after the Closing, the Surviving
Corporation) and their respective officers, directors, employees, stockholders,
agents and representatives against, and agrees to hold them harmless from, any
loss, liability, claim, damage or expense (including reasonable legal fees and
expenses) ("Losses"), as incurred (payable quarterly upon written request), for
or on account of or arising from or in connection with or otherwise with respect
to (i) any breach of any covenant of WRI contained in this Agreement or any
document delivered in connection herewith and (ii) the Retained Liabilities.

          (b) ONEOK, and from and after the Closing, the Surviving Corporation,
hereby agrees to indemnify WRI and its Affiliates and their respective officers,
directors, employees, stockholders, agents and representatives against, and
agrees to hold them harmless from, any Losses, as incurred (payable quarterly
upon written request), for or on account of or arising from or in connection
with or otherwise with respect to (i) any breach of any covenant of ONEOK
contained in this Agreement or any document delivered in connection herewith and
(ii) the Assumed Liabilities.

          (c) In order for a party (the "indemnified party"), to be entitled to
any indemnification provided for under this Agreement in respect of, arising out
of or involving a claim made by any person against the indemnified party (a
"Third Party Claim"), such indemnified party must notify the indemnifying party
in writing of the Third Party Claim within a reasonable time after receipt by
such indemnified party of written notice of the Third Party Claim unless the
indemnifying party shall have previously obtained actual knowledge thereof.
Thereafter, the indemnified party shall deliver to the indemnifying party,
within a reasonable time after the indemnified party's receipt thereof, copies
of all notices and documents (including court papers) received by the
indemnified party relating to the Third Party Claim.



                                       74
<PAGE>   86

          (d) If a Third Party Claim is made against an indemnified party, the
indemnifying party will be entitled to participate in the defense thereof and,
if is so chooses, to assume the defense thereof with counsel selected by the
indemnifying party; provided such counsel is not reasonably objected to by the
indemnified party; and provided further that the indemnifying party first admits
in writing its liability to the indemnified party with respect to all material
elements of such claim. Should the indemnifying party so elect to assume the
defense of a Third Party Claim, the indemnifying party will not be liable to the
indemnified party for any legal expenses subsequently incurred by the
indemnified party in connection with the defense thereof. If the indemnifying
party elects to assume the defense of a Third Party Claim, the indemnified party
will (i) cooperate in all reasonable respects with the indemnifying party in
connection with such defense, (ii) not admit any liability with respect to, or
settle, compromise or discharge, any Third Party Claim without the indemnifying
party's prior written consent and (iii) agree to any settlement, compromise or
discharge of a Third Party Claim which the indemnifying party may recommend and
which by its terms obligates the indemnifying party to pay the full amount of
the liability in connection with such Third Party Claim, which releases the
indemnified party completely in connection with such Third Party Claim and which
would not adversely affect the business carried on by the indemnified party. In
the event the indemnifying party shall assume the defense of any Third Party
Claim, the indemnified party shall be entitled to participate in (but not
control) such defense with its own counsel at its own expense. If the
indemnifying party does not assume the defense of any such Third Party Claim,
the indemnified party may defend the same in such manner as it may deem
appropriate, including but not limited to settling such claim or litigation
after giving notice to the indemnifying party of such terms and the indemnified
party will promptly reimburse the indemnified party upon written request.
Anything contained in this Agreement to the contrary notwithstanding, the
indemnifying party shall not be entitled to assume the defense of any Third
Party Claim if the Third Party Claim seeks an order, injunction or other
equitable relief or relief for other than money damages against the indemnified
party which, if successful, would adversely affect the business of the
indemnified party.

          10.2 Tax Indemnification and Audits. (a) From and after the Closing,
WRI shall indemnify and hold harmless the Surviving Corporation, Westar and MCMC
against (i) any and all liability assessed against the Surviving Corporation,
Westar or MCMC for Income Taxes with respect to taxable periods ending on or
before the Closing Date; (ii) any liability assessed against the Surviving
Corporation, Westar or MCMC by reason of the Surviving Corporation, Westar or
MCMC being severally liable for Income Taxes of WRI or any of its Affiliates
pursuant to Treasury Regulation Section 1.1502-6 (or any analogous provision of
state, local or foreign tax law); and (iii) except to the extent taken into
account as a Current Liability in the calculation of Closing Working Capital,
any liability for Pre-Closing Straddle Period Income Taxes assessed against the
Surviving Corporation, Westar or MCMC (other than Pre-Closing Straddle Period
Income Taxes for which WRI has paid the Surviving Corporation pursuant to
Section 6.15(c)), including without limitation in each of (i) through (iii)
above, any liability resulting from changes made on audit. For purposes of
clauses (i) and (iii) of the preceding sentence, the taxable year of any
partnership or other pass-through entity in which WRI, the Surviving Corporation
or any of the Transferred Subsidiaries is a partner or other beneficial interest
holder shall be deemed to terminate at the close of business on the Closing
Date. Any indemnification payable by WRI to the Surviving Corporation, Westar or
MCMC pursuant to this Section 10.2(a) shall be paid within the later of five
days of the Surviving Corporation's request therefor and five days prior to the
date on which the liability upon which the indemnification is based is required
to be satisfied by the Surviving Corporation or Westar and MCMC, as the case may
be.

<PAGE>   87

          (b) Each party shall promptly notify the other in writing upon receipt
of notice of any pending or threatened federal, state, local or foreign Tax
audits or assessments which may affect the Tax liabilities of the Surviving
Corporation, Westar or MCMC with respect to periods ending on or before the
Closing Date; provided, however, that the failure of the Surviving Corporation
to give WRI prompt notice as provided herein shall not relieve WRI of any of its
obligations hereunder, except to the extent that WRI's position is actually and
materially prejudiced as a result of such failure. WRI shall, at its own
expense, control any audit or determination by any authority, initiate any claim
for refund or amended return, and contest, resolve and defend against any
assessment, notice of deficiency, or other adjustment or proposed adjustment of
Income Taxes of the Surviving Corporation, Westar or MCMC (collectively, an
"Income Tax Contest") attributable to taxable periods ending on or before the
Closing Date, and shall be responsible for the timely payment of any liability
for Income Taxes that relate to such periods; provided, however, that to the
extent such audit or assessment relates to an Income Tax for which the Surviving
Corporation, Westar or MCMC could be held liable or affects the amount of Income
Taxes to be paid or caused to be paid by the Surviving Corporation, the
Surviving Corporation shall have the right to participate in any such Income Tax
Contest in the manner it deems appropriate and WRI shall be prohibited from
reaching a settlement with regard to such Income Tax Contest without the
Surviving Corporation's consent, which consent shall not be unreasonably
withheld. the Surviving Corporation shall, at its own expense, control all
Income Tax Contests attributable to taxable periods ending after the Closing
Date, and shall be responsible for the timely payment of any liability for
Income Taxes that relate to such periods; provided, however, that to the extent
such audit or assessment relates to an Income Tax for which WRI could be held
liable or affects the amount of Income Taxes to be paid or caused to be paid by
WRI, WRI shall have the right to participate in any such Income Tax Contest in
the manner it deems appropriate and the Surviving Corporation shall be
prohibited from reaching a settlement with regard to such Income Tax Contest
without WRI's consent, which consent shall not be unreasonably withheld.

          (c) Any refunds or credits of Income Taxes of Westar or MCMC received
by or credited to the Surviving Corporation or Westar and MCMC attributable to
periods ending on or before the Closing Date or to such portions of Straddle
Periods ending at the close of business on the Closing Date, (collectively,
"WRI's Refunds"), shall be for the benefit of WRI. the Surviving Corporation
shall cause any such refund (net of any Tax liability resulting from such
refund) to be paid to WRI within ten days of the Surviving Corporation's or
Westar and MCMC's receipt thereof.



                                       76
<PAGE>   88

          (d) WRI agrees that if Westar or MCMC carries back any item of loss,
deduction or credit which arises in any taxable period ending after the Closing
Date into any taxable period beginning before the Closing Date, then Westar or
MCMC (as appropriate) shall be entitled to any Tax benefit or refund of Taxes
realized as a result thereof (after giving priority to any existing Tax
attributes of WRI). The Surviving Corporation and WRI shall negotiate in good
faith to resolve any dispute with respect to the calculation of any such
benefit. Any unresolved disputes with respect to the calculation of any such Tax
benefits shall be submitted to a "Big Six" accounting firm for arbitration, the
costs of which shall be shared equally by the Surviving Corporation and WRI.

                                   ARTICLE XI

<PAGE>   15


Ownership Percentage, in each case other than as permitted pursuant to the terms
of this Agreement, then the Shareholder shall, or shall cause the Shareholder
Affiliates to, consistent with the provisions of Section 3.4 of this Agreement,

         Section 3.3. Top-Up Rights; Dilutive Issuance Right. (a) During the
term of this Agreement and prior to the occurrence of a Regulatory Change, but
not thereafter:

         (i) If the Shareholder Group's Voting Ownership Percentage falls below
    the Unrestricted Ownership Percentage, the Shareholder may at its option (A)
    purchase Voting Securities from time to time in the open market or otherwise
    or (B) convert shares of Convertible Preferred Stock into shares of Common
    Stock pursuant to the terms of the Charter, in each case in an amount
    sufficient in order to restore the Shareholder Group's Voting Ownership
    Percentage to the Unrestricted Ownership Percentage.

         (ii) If the Shareholder Group's Total Ownership Percentage falls below
    the Maximum Ownership Percentage, the Shareholder may at its option purchase
    Voting Securities from time to time in the open market or otherwise in an
    amount sufficient in order to restore the Shareholder Group's Total
    Ownership Percentage to the Maximum Ownership Percentage; provided, however
    that the Shareholder shall present for exchange, and the Company shall
    exchange at no cost to the Shareholder, Common Stock purchased pursuant to
    this paragraph for shares of Series B Convertible Preferred Stock (at a
    ratio of one share of Series B Convertible Preferred Stock in exchange for
    each share of Common Stock (as appropriately adjusted to reflect any stock
    split, stock dividend, reverse stock split, reclassification or any other
    transaction with a comparable effect)) in an amount sufficient to ensure
    that the Shareholder Group is in compliance with its obligations under
    Section 3.1(a) hereof.

         (iii) If the Shareholder Group's Total Ownership Percentage would fall
    below the Maximum Ownership Percentage as a result of any security issuance
    (a "Dilutive Issuance") by the Company, except as provided in paragraph
    3.3(a)(v) below, the Shareholder shall have the right (the "Dilutive
    Issuance Right") to require the Company to issue to the Shareholder (A)
    additional Common Stock, up to the maximum number of such shares that would
    permit the Shareholder Group to remain in compliance with Section 3.1(a)
    hereof, and (B) additional shares of Series B Convertible Preferred Stock,
    up to an amount of such shares of Common Stock and Series B Convertible
    Preferred Stock as may be necessary to restore the Shareholder Group's Total
    Ownership Percentage to the Maximum Ownership Percentage. Shares of Common
    Stock or Series B Preferred Stock issued pursuant to the exercise of a
    Dilutive Issuance Right shall be


                                      -12-
<PAGE>   16

    issued for cash concurrently with the closing of the Dilutive Issuance. The
    issue price per share for shares of Common Stock and shares of Series B
    Convertible Preferred Stock issued pursuant to the Dilutive Issuance Right
    shall be equal to the issue price per share of the Dilutive Issuance. Such
    issue price shall in turn be equal to the aggregate amount of cash plus the
    fair market value of any other property received by the Company in
    consideration of the Dilutive Issuance, divided by the number of shares
    being issued in such Dilutive Issuance, with such fair market value being
    determined in good faith by the Board of Directors of the Company, provided
    that if the Shareholder shall object to such valuation within 30 days of its
    receipt of notice thereof, then the fair market value of such property shall
    be determined at the Company's sole expense by an independent nationally
    recognized financial advisor mutually acceptable to the Shareholder and the
    Company.

         (iv) The Shareholder must provide the Company with notice of its
    intention to exercise the Dilutive Issuance Right sixty (60) days prior to
    the expected closing of the Dilutive Issuance, which expected closing date
    will be provided to the Shareholder by or on behalf of the Company not less
    than ninety (90) days prior to such expected closing date.

         (v) The Company shall not be obligated to provide the Shareholder with
    a Dilutive Issuance Right (I) in connection with issuances of securities
    pursuant to employee benefit plans and programs of the Company in the
    ordinary course of business or (II) which would require the issuance of
    fewer than 25,000 shares of Series B Convertible Preferred Stock; provided,
    however, that any share issuances not required to be made pursuant to this
    clause (II) shall be carried forward and taken into account in determining
    whether the Company must provide the Shareholder with a subsequent Dilutive
    Issuance Right. In addition, in the case of any Dilutive Issuance in
    connection with any acquisition or other business combination transaction,
    by merger or otherwise, by the Company, the Company shall be required to
    provide the Shareholder with a Dilutive Issuance Right only to the extent of
    restoring the Shareholder Group's Total Ownership Percentage to the Adjusted
    Maximum Ownership Percentage.

         (vi) At the Closing, the Shareholder shall be entitled to require the
    Company to issue to the Shareholder, at a price per share equal to the
    Market Price as of the date of the Closing, additional Common Stock up to
    the maximum number of shares that would permit the Shareholder Group to
    remain in compliance with Section 3.1(a) and additional shares of Series A
    Convertible Preferred Stock so as to restore the Shareholder Group's Total
    Ownership Percentage to the Maximum Ownership Percentage.

         (b) From time to time following a Regulatory Change and during the term
of this Agreement:


                                      -13-
<PAGE>   17


         (i) If the Shareholder Group's Total Ownership Percentage falls below
    the Maximum Ownership Percentage, the Shareholder may at its option purchase
    Voting Securities from time to time in the open market or otherwise in an
    amount sufficient in order to restore the Shareholder Group's Total
    Ownership Percentage to the Maximum Ownership Percentage.

         (ii) If the Shareholder Group's Total Ownership Percentage would fall
    below the Adjusted Maximum Ownership Percentage as a result of a Dilutive
    Issuance by the Company pursuant to primary or secondary offerings, mergers,
    acquisitions or otherwise, the Shareholder shall have a Dilutive Issuance
    Right (for the issuance of Common Stock only and not Series B Convertible
    Preferred Stock) to the extent of restoring the Shareholder Group's
    Ownership Percentage to the Adjusted Maximum Ownership Percentage.

         (iii) The Shareholder must provide the Company with notice of its
    intention to exercise the Dilutive Issuance Right sixty (60) days prior to
    the expected closing of the Dilutive Issuance, which expected closing date
    will be provided to the Shareholder by or on behalf of the Company not less
    than ninety (90) days prior to such expected closing date.

         (c) All Securities acquired by purchase or conversion pursuant to this
Section 3.3 shall be subject to the terms of this Agreement. In no event shall
the Shareholder Group's exercise of the Dilutive Issuance Right be interpreted
to be a waiver by the Shareholder of its right to make purchases of Securities
pursuant to this Section.

         Section 3.4. Restrictions on Transfer. None of the members of the
Shareholder Group shall directly or indirectly Transfer any Voting Securities
without the prior written consent of a majority of the Independent Directors,
except the following Transfers:

         (a) Transfers of Securities representing upon Transfer Voting Power of
    less than 5.0% to any Transferee, without prior notice to the Company, so
    long as such Transferee and any Affiliate of such Transferee and any such
    person who is a member of a 13D Group with such Transferee does not have a
    Voting Ownership Percentage of 5.0% or more immediately prior to giving
    effect to at the time of each such Transfer.

         (b) Transfers of Securities representing upon Transfer Voting Power of
    5.0% or more pursuant to the following procedure (the "Sale Option"):

              (i) The Seller must provide written notice (a "Sale Notice") of
         its intention to sell to the Company Securities representing, upon
         Transfer, Voting Power of 5.0% or more (the "Sale Securities"). The
         Sale Notice shall specify the number of Sale Securities and the cash
         price per share at which the Company or its designee may purchase the
         Sale Securities, which cash price shall equal


                                      -14-
<PAGE>   18

         98.5% of the Market Price of such Sale Securities determined as of the
         date of the Sale Notice; provided, however, that the cash price per
         share at which the Company or its designee shall purchase shares of
         Convertible Preferred Stock pursuant to this subsection shall equal
         98.5% of the Market Price of the Common Stock determined as of the date
         of the Sale Notice.

              (ii) The Company shall have a period ending on the later of ninety
         (90) days after the date of the Sale Notice and thirty (30) days from
         the date of receipt of all necessary regulatory approvals (the "Sale
         Period") (provided, that in no event shall the Sale Period exceed one
         hundred eighty (180) days) within which to effect a closing of the
         Company's or its designee's purchase of all, but not less than all, of
         the Sale Securities.

              (iii) If the Company or its designee shall for any reason fail to
         effect a closing of the purchase of all, but not less than all, of the
         Sale Securities within the Sale Period, the Company shall at its option
         inform the Seller in writing that it shall reimburse the Seller for the
         aggregate difference between the Market Price of the Sale Securities as
         of the date of the Sale Notice and the Market Price of the Sale
         Securities as of the date that the Seller completes its transfer of the
         Sale Securities, in which event such transfer by the Seller must be
         completed within the later of 180 days from the date of the Sale Notice
         or 30 days from the receipt of all necessary regulatory approvals.
         Otherwise, if the Company shall not have so informed the Seller, the
         Seller shall have 16 months from the date of the Sale Notice to
         complete such transfer. In the event that such transfer by the Seller
         is not so completed within the applicable period, the Sale Securities
         shall thenceforth again be subject to this Section 3.4.

         (c) Transfers of Securities to the public in a bona fide underwritten
    offering pursuant to the Registration Rights Agreement; provided, however,
    that the Seller and the representative or representatives of the
    underwriters previously agree in writing with the Company that all
    reasonable efforts will be made to achieve a wide distribution of the Voting
    Securities in such offering and to ensure that no Transferee in such
    offering acquires for its own account Beneficial Ownership of Securities
    representing upon Transfer Voting Power of 5.0% or more.

         (d) Transfers of all or part of the Shareholder Group's Securities
    pursuant to a pro rata distribution of Securities among the shareholders of
    the Shareholder.

         (e) Transfers of Securities among members of the Shareholder Group;
    provided, however, that any such transferee shall agree with the Company in
    writing prior to each such transfer to be bound by the terms of this
    Agreement with respect to its Beneficial Ownership of Securities.


                                      -15-
<PAGE>   19


         (f) If a Clearly Credible Tender Offer for the Company has been
    commenced, at the Shareholder's option Transfers of Securities by means of
    tenders into such Clearly Credible Tender Offer in an amount not exceeding
    the percentage (on the basis of total Votes and assuming the conversion of
    all shares of Convertible Preferred Stock into shares of Common Stock) of
    the Voting Securities of which it is the Beneficial Owner equal to the
    highest percentage (on the basis of total Votes) of the aggregate of all
    Voting Securities not Beneficially Owned by any member of the Shareholder
    Group which has ever been announced to have been tendered into such Clearly
    Credible Tender Offer.

         Section 3.5. Buy-Back Options. (a) During the term of this Agreement,
if the Company purchases Securities from the public, whether by tender offer,
open market purchase or otherwise (a "Repurchase"), the Company shall
contemporaneously with the Repurchase offer to repurchase from the Shareholder
on the same terms and conditions, including price, as in the Repurchase, a
percentage (on the basis of total Votes and assuming the conversion of all
shares of Convertible Preferred Stock into shares of Common Stock) of those
Securities Beneficially Owned by the Shareholder equal to the percentage (on the
basis of total Votes and assuming the conversion of all shares of Convertible
Preferred Stock into shares of Common Stock) of Securities to be Repurchased
from the Beneficial Owners of Securities other than the Shareholder or any
Shareholder Affiliate (the "Buy-Back Offer"). The Shareholder may accept such
Buy- Back Offer in its sole discretion; provided, however, that in the event of
a Repurchase the Shareholder shall be required to sell Securities or Voting
Securities of which it is the Beneficial Owner to the Company in an amount
sufficient to ensure that its Total Ownership Percentage does not exceed the
Maximum Ownership Percentage and/or, prior to the occurrence of a Regulatory
Change and not thereafter, that the Shareholder Group's Voting Ownership
Percentage does not exceed the Unrestricted Ownership Percentage, in each case
other than as permitted pursuant to the terms of this Agreement; and provided
further that the Shareholder shall not be required to comply with the preceding
mandatory sale requirement (i) during any period when doing so would cause the
Shareholder to incur any liability under Section 16(b) of the Exchange Act or
the rules and regulations promulgated thereunder, and (ii) to the extent that
compliance with such mandatory sale requirement would have an adverse effect on
the availability of pooling-of-interests accounting treatment with respect to
any business combination involving the Shareholder or any of the Shareholder's
subsidiaries that has either been announced or is under bona fide consideration
by the Shareholder at the time of such Repurchase, but the Shareholder shall be
required to comply with such mandatory sale requirement immediately upon the
conditions set forth in (i) and (ii) above no longer being applicable. Any
Securities Beneficially Owned by the Shareholder Group as permitted by the
preceding sentence which cause the Shareholder Group's Total Ownership
Percentage to exceed the Maximum Ownership Percentage and/or, prior to the
occurrence of a Regulatory Change and not thereafter, the Shareholder Group's
Voting Ownership Percentage to exceed the Unrestricted Ownership Percentage
shall be referred to in this Agreement as "Excess Buy-Back Securities."

         (b) The Company shall provide notice to the Shareholder of its
intention to engage in a Repurchase not less than 30 days in advance of the date
on which the Repurchase is to begin


                                      -16-
<PAGE>   20


(the "Company Repurchase Notice"). The Shareholder must provide notice to the
Company within ten (10) days of receipt of the Company Repurchase Notice of (i)
whether the Shareholder intends to accept the Buy-Back Offer and (ii) in good
faith whether the Shareholder is aware that the Shareholder would be subject to
any of the conditions set forth in (i) or (ii) above as a result of such
Repurchase.

         Section 3.6. Buy/Sell Option. (a) At the fifteenth and at each
succeeding anniversary of the date hereof, if at such times this Agreement
remains in force, each of the Shareholder and the Company may at its option (the
"Buy/Sell Option") provide notice (the "Buy/Sell Notice") to the other party of
a price (the "Buy/Sell Price") at which such notifying party intends in good
faith either to sell to the receiving party all, but not less than all, of the
Securities Beneficially Owned by the notifying party or to buy from the
receiving party all, but not less than all, of the Securities Beneficially Owned
by the receiving party; provided, however, that the Buy/Sell Price shall apply
equally to shares of Convertible Preferred Stock and shares of Common Stock and
provided, further, that all references in this Section 3.6 to Securities
Beneficially Owned by the Company shall be deemed to refer only to outstanding
Securities Beneficially Owned by shareholders of the Company other than the
Shareholder Group.

         (b) Upon receipt by the Shareholder of a Buy/Sell Notice from the
Company, the Shareholder Group shall have ninety (90) days (the "Shareholder
Decision Period") within which either to (i) agree to sell for cash all, but not
less than all, of the Securities Beneficially Owned by the Shareholder Group to
the Company at the Buy/Sell Price or (ii) make a bona fide Clearly Credible
Tender Offer (a "Buyout Tender Offer") at the Buy/Sell Price for any and all
Securities Beneficially Owned by the Company, which Buyout Tender Offer the
Company hereby agrees not to oppose. A non-waivable condition to the
consummation of the Buyout Tender Offer shall be the valid tender into such
offer, on or prior to the 20th day following the receipt of all regulatory
approvals required for the consummation of such offer, of Voting Securities
representing in the aggregate two-thirds (2/3) of the Voting Power represented
by all Voting Securities held by shareholders of the Company other than the
Shareholder Group.

         (c) (i) Upon receipt by the Company of a Buy/Sell Notice from the
Shareholder, the Company shall have ninety (90) days (the "Company Decision
Period") within which to (A) agree to purchase for cash all but not less than
all of the Securities Beneficially Owned by the Shareholder Group at the
Buy/Sell Price or (B) agree to seek an opinion from an independent,
internationally recognized investment banking firm relating to the fairness to
the Company's shareholders of the Offer Price in the Buyout Tender Offer with
respect to the acquisition by the Shareholder of all Securities Beneficially
Owned by the Company at the Buy/Sell Price.

              (ii) If the Company shall not agree to repurchase the Voting
         Securities Beneficially Owned by the Shareholder Group pursuant to
         Section 3.6(c)(i) above, the Company shall have the right, within
         ninety (90) days following the end of the Company Decision Period, to
         obtain the fairness opinion and execute a merger agreement between the
         Company and any member of the Shareholder Group pursuant to which the
         Shareholder or a Shareholder Affiliate shall acquire Beneficial
         Ownership of all remaining Securities at the Buy/Sell Price. The terms
         of such merger agreement shall include customary provisions regarding
         the non- solicitation of alternative transactions by the Company and
         the recommendation of the Merger to the Company's shareholders, if
         required.

              (iii) If the Company fails to satisfy the condition pursuant to
         Section 3.6(c)(ii) above by the end of such ninety (90) day period, or
         if the Company cannot obtain a fairness opinion by the end of such
         ninety (90) day period, this Agreement shall immediately terminate.

         (d) If the Shareholder and the Company each provide a Buy/Sell Notice
to the other party on the same day, the Buy/Sell Notice containing the higher
valued Buy/Sell Price shall be the effective and controlling Buy/Sell Notice. In
the event that (i) the Buy/Sell Price set forth in either or both of the
Buy/Sell Notices consists of consideration other than cash, and (ii) the parties
are unable to reach agreement as to which of the Buy/Sell Prices is higher
valued for purposes of this subsection (d), an independent, internationally
recognized investment banking firm mutually agreeable to both parties shall
conclusively make such determination.

         (e) Any purchase by the Company of the Shareholder Group's Securities
pursuant to this Section shall be closed within a period ending ninety (90) days
after the end of the Shareholder Decision Period or the Company Decision Period,
as the case may be, or thirty (30) days after the date of receipt of all


                                      -18-

necessary regulatory approvals, whichever is later.

         Section 3.7 Charter and By-Laws. During the term of this Agreement the
Company shall not amend, alter or repeal, or propose the amendment, alteration
or repeal of, any provision of the Charter or the By-Laws in any manner which is
inconsistent with the terms of this Agreement and which adversely affects the
rights of the Shareholder Group under the terms of this Agreement. If at any
time during the term of this Agreement the provisions of this Agreement shall
conflict with the provisions of the Charter and the By-Laws, the provisions of
this Agreement shall be controlling.

         Section 3.8. Rights Agreement. During the term of this Agreement, the
Company hereby agrees not to amend any provision of the Rights Agreement in any
manner which is inconsistent with the terms of this Agreement or the Merger
Agreement and which adversely affects the rights of the Shareholder Group under
the terms of this Agreement.

         Section 3.9. Agreement Not to Convert. During the term of this
Agreement and prior to the occurrence of a Regulatory Change, the Shareholder
agrees that it shall not, and shall cause each Shareholder Affiliate not to,
Convert shares of Convertible Preferred Stock Beneficially Owned by the
Shareholder or any Affiliate into shares of Common Stock except to the extent
any such shares of Convertible Preferred Stock are Converted (a) concurrently
with


                                     -19-
<PAGE>   22


the Transfer of such shares to any Person other than the Shareholder or any
Shareholder Affiliate or (b) pursuant to the Shareholder's top-up rights as set
forth in Section 3.3(a)(i)(B).

         Section 3.10. Taxes Upon Conversion or Exchange. The Company hereby
agrees to pay any and all stock transfer and documentary stamp taxes that may be
payable in respect of any issuance or delivery of (i) any shares of Convertible
Preferred Stock, (ii) any shares of Common Stock issued in a Conversion of
shares of Convertible Preferred Stock, or (iii) any exchange of shares of Common
Stock for shares of Convertible Preferred Stock, or certificates or instruments
evidencing any of such shares or securities. The Company shall not, however, be
required to pay any such tax which may be payable in respect of any transfer
involved in the issuance or delivery of shares of Common Stock in a Conversion
of shares of Convertible Preferred Stock in a name other than that in which the
shares of such Convertible Preferred Stock were registered.

         Section 3.11. Make Whole Payment. Immediately upon the Conversion of
any share of Series A Preferred Stock, the Company shall pay to the Shareholder
an amount (a "Make Whole Payment") with respect to such share equal to the Total
Make Whole Amount for such share as of the date of such Conversion; provided,
however, that the Company shall not be required to make a Make Whole Payment in
respect of the Conversion of fewer than 25,000 shares of Series A Convertible
Preferred Stock; provided, further, that any Make Whole Payments not required to
be made pursuant to this sentence shall be carried forward and taken into
account in determining whether the Company must provide the Shareholder with a
subsequent Make Whole Payment.

         Section 3.12. Prohibition on Senior Securities. During the term of this
Agreement, the Company hereby agrees that it shall not create, authorize or
reclassify any authorized stock of the Company into (x) any class or series of
the Company's capital stock ranking prior to the Convertible Preferred Stock as
to dividends or as to distributions of assets upon liquidation, dissolution or
winding up of the Company, whether voluntary or involuntary, or (y) any class or
series of the Company's capital stock entitled to vote separately as a class on
any matter whatsoever, other than an amendment to the Charter which would have
the effect of modifying the voting powers, designations, preferences, rights and
qualifications, limitations or restrictions of such class or series so as to
affect the holders thereof adversely, or (z) any security convertible into
shares of any class or series described in (x) or (y) above.

                         Board Representation and Voting

         Section 4.1. Directors Designated by the Shareholder. (a) Immediately
following the Closing, the Board shall expand the size of the Board by two (2)
Directors and shall appoint as additional Directors the two (2) Initial
Shareholder Nominees (as defined in Section 4.1(b) below) who have been
designated by the Shareholder in the Initial Shareholder Nominee Notice (as
defined in Section 4.1(b)


                                      -20-
<PAGE>   23


below) attached as Exhibit C hereto. One Initial Shareholder Nominee shall be
placed in the class of Directors next standing for election, and the remaining
Initial Shareholder Nominee shall be placed in the class of Directors next but
one standing for election. Immediately following the occurrence of a Regulatory
Change, the Board shall expand the Board as may be necessary and shall appoint
additional Initial Shareholder Nominees as designated by the Shareholder in an
additional Initial Shareholder Nominee Notice in a number sufficient to ensure
that Shareholder Nominees comprise a number of Directors which is (x) 4
Directors if the total size of the Board is 14 or fewer Directors (excluding any
Shareholder Nominees) or (y) one-third (rounding down to the nearest whole
Director) of the Board (if the total size of the Board is more than 14 Directors
(excluding any Shareholder Nominees). Such additional Initial Shareholder
Nominees shall be distributed among the classes of Directors as evenly as
possible. In the event of a vacancy caused by the disqualification, removal,
resignation or other cessation of service of any Initial Shareholder Nominee
from the Board, the Board shall elect as a Director (to serve until the
Company's immediately succeeding annual meeting of shareholders) a new Initial
Shareholder Nominee who has been designated by the Shareholder in an additional
Initial Shareholder Nominee Notice that has been provided to the Company at
least seven (7) days prior to the date of a regular meeting of the Board.

         (b) The Shareholder shall provide notice to the Company (the "Initial
Shareholder Nominee Notice") as required by Section 4.1(a) above, which notice
shall contain the following information: (i) the name of the person(s) it has
designated to become Director(s) (the "Initial Shareholder Nominees"), and (ii)
all information required by Regulation 14A and Schedule 14A under the Exchange
Act with respect to each such Initial Shareholder Nominee.

         (c) Following the occurrence of a Regulatory Change and during the term
of this Agreement, until such time as the Initial Shareholder Nominees and the
Successor Shareholder Nominees (as defined in Section 4.1(d) below) together
comprise a number of Directors which is one-third (rounding down to the nearest
whole Director) of the Board, at the first annual meeting of shareholders of the
Company following the occurrence of a Regulatory Change and at each subsequent
annual meeting of shareholders of the Company at which (i) the term of any
Director is to expire or (ii) a vacancy is caused by the removal, resignation,
retirement, death, disability or disqualification or other cessation of service
of any Director, the Company shall at its option (i) cause such directorship to
remain vacant, with the size of the Board correspondingly being reduced, or (ii)
designate as a replacement Director a Successor Shareholder Nominee to be
included in the slate of nominees recommended by the Board to the Company's
shareholders for election as Directors and use its best efforts to cause the
election of each such Successor Shareholder Nominee to the Board, including
soliciting proxies in favor of the election of such persons. The Successor
Shareholder Nominees shall be divided as nearly equally as possible among all
the classes of Directors, as specified in the Successor Shareholder Nominee
Notice (as defined in Section 4.1(d) below).


                                     -21-

         (d) Following the occurrence of a Regulatory Change and during the term
of this Agreement, until such time as the Initial Shareholder Nominees and the
Successor Shareholder Nominees together comprise a number of Directors which is
one-third (rounding down to the nearest whole Director) of the Board, the
Shareholder shall provide notice to the Company in writing sixty (60) days prior
to each annual meeting of the Company's shareholders ("Successor Shareholder
Nominee Notice"), indicating (i) the name of the person(s) it has designated to
become Director(s) ("Successor Shareholder Nominees" and together with Initial
Shareholder Nominees, "Shareholder Nominees"), if any, (ii) the class of
Directors to which each such Successor Shareholder Nominee shall be assigned,
and (iii) all information required by Regulation 14A and Schedule 14A under the
Exchange Act with respect to each such Successor Shareholder Nominee.

         (e) The Shareholder shall consult with the Company in connection with
the identity of any proposed Shareholder Nominee. In the event the Company is
advised in writing by its outside counsel that a proposed Shareholder Nominee
would not be qualified under the Company's Charter or By-Laws or any applicable
statutory or regulatory standards to serve as a Director, or if the Company
otherwise reasonably objects to a proposed Shareholder Nominee, including
without limitation because such Shareholder Nominee either (i) is a director or
officer of a direct competitor of the Company or (ii) has engaged in any adverse
conduct that would require disclosure under Item 7 of Schedule 14A promulgated
under the Exchange Act, the Shareholder agrees to withdraw such proposed
Shareholder Nominee and nominate a replacement therefor (which replacement would
be subject to the requirements of this Section 4.1(e)). Any such objection by
the Company must be made no later than one (1) month after the Shareholder first
informs the Company of the identity of the proposed Shareholder Nominee;
provided, however, that the Company shall in all cases notify the Shareholder of
any such objection sufficiently in advance of the date on which proxy materials
are mailed by the Company in connection with such election of directors to
enable the Shareholder to propose an alternate Shareholder Nominee pursuant to
and in accordance with the terms of this Agreement. Prior to the occurrence of a
Regulatory Change, no more than one Shareholder Nominee may be a director,
officer or employee of the Shareholder. Following the occurrence of a Regulatory
Change, no more than two (2) Shareholder Nominees may be directors, officers or
employees of the Shareholder.

         (f) During the term of this Agreement the Company agrees to include
each Shareholder Nominee to be added to or retained on the Board pursuant to
this Agreement in the slate of nominees recommended by the Board to the
Company's shareholders for election as Directors and shall use its best efforts
to cause the election or reelection of each such Shareholder Nominee to the
Board, including soliciting proxies in favor of the election of such persons.

         (g) During the term of this Agreement and prior to the occurrence of a
Regulatory Change, but not thereafter, no Shareholder Nominee shall chair a
committee of the Board and no Shareholder Nominee shall serve on the Nominating
Committee of the Board. Following the


                                      -22-
<PAGE>   25


occurrence of a Regulatory Change and during the term of this Agreement, the
Shareholder shall be entitled to designate Shareholder Nominees to be members of
each committee of the Board (including without limitation the executive
committee, the audit committee, the nominating committee and the executive
compensation committee), and to fill any vacancies caused by the departure of
Shareholder Nominees from any such committees if no other Shareholder Nominee is
a member of such committee, for so long as Shareholder Nominees are not
represented pro rata, based on the number of Directors who are Shareholder
Nominees (rounding down to the nearest whole Director), with respect to each
committee of the Board.

         Section 4.2. Resignation of Shareholder Nominees. Unless otherwise
agreed by the Company, the Shareholder shall cause each of the Shareholder
Nominees then serving on the Board to offer their resignations from the Board
immediately upon the earlier to occur of the following:

         (a) The termination of this Agreement pursuant to and in accordance
    with Section 5.2 hereof; and

         (b) The Shareholder Group's Total Ownership Percentage falling below
    10.0%.

         Section 4.3. Voting. During the term of this Agreement, the
Shareholder, as a holder of shares of Voting Securities, agrees that:

         (a) The Shareholder shall, and shall cause each Shareholder Affiliate
to, be present, in person or by proxy, at all meetings of shareholders of the
Company so that all Voting Securities having voting rights which are
Beneficially Owned by the Shareholder and the Shareholder Affiliates may be
counted for the purpose of determining the presence of a quorum at such
meetings.

         (b) With respect to the election of Directors, the Shareholder shall,
and shall cause each Shareholder Affiliate to, vote all Voting Securities
Beneficially Owned by the Shareholder and any Shareholder Affiliate in favor of
the election of all candidates for Director nominated by the Company's Board
(including the Shareholder Nominees).

         (c) With respect to all other matters submitted to a vote of the
Company's shareholders, prior to the occurrence of a Regulatory Change, but not
thereafter, and during the term of this Agreement, the Shareholder and any
member of the Shareholder Group may vote any or all of the Voting Securities
Beneficially Owned by them, in their sole discretion. Following the occurrence
of a Regulatory Change and during the term of this Agreement, (i) the
Shareholder and each member of the Shareholder Group may vote in their sole
discretion a number of Voting Securities Beneficially Owned by the Shareholder
Group having voting rights with respect to such other matters representing in
the aggregate a Voting Ownership Percentage not in excess of the Unrestricted
Ownership Percentage, and (ii) the Shareholder shall, and shall cause each
member of the Shareholder Group to, vote all Voting Securities Beneficially
Owned


                                      -23-
<PAGE>   26


by the Shareholder Group having voting rights with respect to such other matters
representing in the aggregate a Voting Ownership Percentage in excess of the
Unrestricted Ownership Percentage in the same proportion (based on total Votes)
as all Voting Securities voted on any such other matter are voted by the
shareholders of the Company other than the Shareholder or any member of the
Shareholder Group, provided, however, that the Shareholder and any member of the
Shareholder Group may vote any or all of the Voting Securities Beneficially
Owned by them in their sole discretion with respect to a vote of the Company's
shareholders on any transaction or series of transactions which would, if
consummated, constitute a Change in Control of the Company. Notwithstanding the
foregoing, at all times prior to or following the occurrence of a Regulatory
Change, the Shareholder shall, and shall cause each member of the Shareholder
Group to, vote all Excess Buy-Back Securities having voting rights with respect
to any matter (including the election of Directors) in the same proportion
(based on total Votes) as all Voting Securities voted on such matter are voted
by the shareholders of the Company other than the Shareholder or any member of
the Shareholder Group.

         (d) At all times the Shareholder Group may exercise in its sole
discretion such voting rights as the Convertible Preferred Stock may have from
time to time pursuant to the Charter and with respect to an amendment to the
Charter which would have the effect of modifying the voting powers,
designations, preferences, rights and qualifications, limitations or
restrictions of such class or series so as to affect the holders thereof
adversely.

provided, further that in no event shall such cure period extend longer than

similar official of the Company or of any substantial part of the Company's
property, or ordering the winding up or liquidation of the Company's affairs;
and the continuance of any such decree or order for relief or any such other

days.

         (j) The commencement by the Company of a voluntary case or proceeding

                                   ARTICLE VI

                                  Miscellaneous

         Section 6.1. Compliance With Law. Notwithstanding anything to the
contrary in this Agreement, no Transfer of Securities shall be deemed to be
required or permitted pursuant to this Agreement if such Transfer would (a)
result in an adverse effect on the exemptions from the 1935 Act of the
Shareholder or any Shareholder Affiliate or the Company or any subsidiary of the
Company, or (b) require regulatory approvals which, individually or in the
aggregate with respect to such Transfer, would have a material adverse impact on
the Company or any of its subsidiaries or the Shareholder or any Shareholder
Affiliate.

         Section 6.2. Regulatory Matters. During the term of this Agreement, the
Company agrees to take all commercially reasonable steps to assist the
Shareholder in (a) with respect to each provision of this Agreement, causing a
Regulatory Change which would not reasonably be expected to have an adverse
effect on the Company to occur as soon as reasonably practicable, and (b)
securing such regulatory approvals as would not reasonably be expected to have a
material adverse effect on the Company and as may be necessary to allow the
Shareholder to exercise its rights under the Agreement at all times, including
without limitation the right of the Shareholder to Transfer Securities free of
the restrictions and limitations imposed by Section 6.1. Following the
occurrence of a Regulatory Change, if the Company believes in good faith that
the Shareholder's regulatory status as modified by such Regulatory Change would
place an unreasonable restriction on the Company's implementation of the
Company's strategic business plan, then the Company shall have an immediate
right to exercise its Buy-Sell Option as provided in Section 3.6 hereof, without
regard to whether Section 3.6 would otherwise then be applicable.

         Section 6.3. Injunctive Relief. Each party hereto acknowledges that it
would be impossible to determine the amount of damages that would result from
any breach of any of the provisions of this Agreement and that the remedy at law
for any breach, or threatened breach, of any of such provisions would likely be
inadequate and, accordingly, agrees that each other party shall, in addition to
any other rights or remedies which it may have, be entitled to seek such
equitable and injunctive relief as may be available from any court of competent
jurisdiction to compel specific performance of, or restrain any party from
violating, any of such provisions. In connection with any action or proceeding
for injunctive relief, each party hereto hereby waives the claim or defense that
a remedy at law alone is adequate and agrees, to the maximum extent permitted by
law, to have each provision of this Agreement specifically enforced against him
or it, without the necessity of posting bond or other security against him or
it, and consents to the entry of injunctive relief against him or it enjoining
or restraining any breach or threatened breach of such provisions of this
Agreement.

         Section 6.4. Successors and Assigns. This Agreement shall be binding
upon, shall inure to the benefit of and shall be enforceable by the Company and
by the Shareholder and their respective successors and permitted assigns, and no
such term or provision is for the benefit of, or intended to create any
obligations to, any other Person.

         Section 6.5. Amendments; Waiver. (a) This Agreement may be amended only
by an agreement in writing executed by the parties hereto. Any approval of an
amendment of this Agreement upon the part of the Company shall require the
approval of a majority of the Independent Directors at a duly convened meeting
thereof or all of the Company's directors by written consent thereto.

         (b) Either party may waive in whole or in part any benefit or right
provided to it under this Agreement, such waiver being effective only if
contained in a writing executed by the waiving party. No failure by any party to
insist upon the strict performance of any covenant, duty, agreement or condition
of this Agreement or to exercise any right or remedy consequent upon breach
thereof shall constitute a waiver of any such breach or of any other covenant,
duty, agreement or condition, nor shall any delay or omission of either party to
exercise any right hereunder in any manner impair the exercise of any such right
accruing to it thereafter. Any waiver of any benefit or right provided to the
Company under this Agreement shall require the approval of a majority of the
Board and a majority of the Independent Directors at a duly convened meeting
thereof or all of the Company's directors by written consent thereto.

         Section 6.6. Notices. Except as otherwise provided in this Agreement,
all notices, requests, claims, demands, waivers and other communications
hereunder shall be in writing and shall be deemed to have been duly given when
delivered by hand, when delivered personally or by courier, three days after
being deposited in the mail (registered or certified mail, postage prepaid,
