                          AGREEMENT AND PLAN OF MERGER

     AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of July 13, 2000,
by and among Hanover Compressor Company, a Delaware corporation ("Parent"),
Caddo Acquisition Corporation, an Oklahoma corporation and a direct wholly owned
subsidiary of Parent ("Merger Sub"), and OEC Compression Corporation, an
Oklahoma corporation (the "Company").

     WHEREAS, the respective Boards of Directors of Parent and Merger Sub have
determined that the merger of Merger Sub with and into the Company, upon the
terms and subject to the conditions set forth in this Agreement (the "Merger"),
is advisable and in the best interests of each corporation and its respective
stockholders;

     WHEREAS, the Board of Directors of the Company has determined that the
Merger is fair to, and in the best interests of, the Company and its
stockholders;

     WHEREAS, the respective Boards of Directors of Parent, Merger Sub and the
Company have each approved and adopted this Agreement and approved the Merger
and the other transactions contemplated hereby;

     WHEREAS, for Federal income tax purposes, it is intended that the Merger
shall qualify as a "reorganization" within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code");

     WHEREAS, contemporaneous with the execution of this Agreement, certain of
the stockholders of the Company listed on Annex I hereto (the "Key
Stockholders") have entered into an agreement in substantially the form of
Exhibit A hereto (the "Voting and Disposition Agreement") to vote all of their
shares of Company Common Stock in favor of the Merger, grant Parent certain
rights to acquire such shares and limit their disposition of Parent Common
Stock;

     WHEREAS, the Company and Dennis W. Estis and Don E. Smith have each entered
into a non-competition and non-solicitation agreement attached as Exhibits B-1
and B-2 hereto;

     NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth below, the
parties agree as follows:

                                  ARTICLE I.

                                  THE MERGER

     Section 1.1. Effective Time of the Merger. Subject to the provisions of
this Agreement, a certificate of merger (the "Certificate of Merger") in such
form as is required by the relevant provisions of the Oklahoma General
Corporation Act (the "OGCA") shall be duly prepared, executed and acknowledged
by the Surviving Corporation and thereafter delivered to
<PAGE>

the Secretary of State of the state of Oklahoma for filing, as provided in the
OGCA, as early as practicable on the Closing Date. The Merger shall become
effective upon the filing of the Certificate of Merger with the Secretary of
State of the state of Oklahoma or such later time as specified in the
Certificate of Merger (the "Effective Time").

     Section 1.2. Closing. The closing of the Merger (the "Closing") will take
place on the second business day, which is any day other than a Saturday, a
Sunday or a day on which U.S. banking institutions are authorized by law,
regulation or executive order to remain closed (a "Business Day"), after
satisfaction or waiver (as permitted by this Agreement and applicable law) of
the conditions (excluding conditions that, by their terms, cannot be satisfied
until the Closing Date) set forth in Article VI (the "Closing Date"), unless
another time or date is agreed to in writing by the parties hereto. The Closing
shall be held at the offices of Latham & Watkins, 5800 Sears Tower, Chicago,
Illinois 60606, unless another place is agreed to in writing by the parties
hereto. The Certificate of Merger shall be filed on or as promptly as
practicable following the Closing Date.

     Section 1.3. Effect of the Merger. As a result of the Merger, the separate
corporate existence of Merger Sub shall cease and the Company shall continue as
the surviving corporation (the "Surviving Corporation"). Upon becoming
effective, the Merger shall have the effects set forth in the OGCA. Without
limiting the generality of the foregoing, and subject thereto, at the Effective
Time, all properties, rights, privileges, powers and franchises of the Company
and Merger Sub shall vest in the Surviving Corporation, and all debts,
liabilities and duties of the Company and Merger Sub shall become the debts,
liabilities and duties of the Surviving Corporation.

     Section 1.4. Certificate of Incorporation; Bylaws. At the Effective Time,
(i) the Certificate of Incorporation of the Company, as in effect immediately
prior to the Effective Time, shall be the Certificate of Incorporation of the
Surviving Corporation, and (ii) the Bylaws of Merger Sub, as in effect
immediately prior to the Effective Time, shall be the Bylaws of the Surviving
Corporation, in each case until duly amended in accordance with applicable law.

     Section 1.5. Directors and Officers. The directors of Merger Sub
immediately prior to the Effective Time shall be the initial directors of the
Surviving Corporation, each to hold office in accordance with the Certificate of
Incorporation and Bylaws of the Surviving Corporation. The officers of the
Company immediately prior to the Effective Time shall be the initial officers of
the Surviving Corporation, each to hold office in accordance with the
Certificate of Incorporation and Bylaws of the Surviving Corporation.

     Section 1.6. Conversion of Capital Stock. As of the Effective Time, by
virtue of the Merger and without any action on the part of the holders of any
shares of the Company's common stock, par value $.01 per share ("Company Common
Stock"), or capital stock of Merger Sub:

                (a) Cancellation of Stock. Each share of Company Common Stock
        that is owned by the Company or any wholly owned subsidiary of the
        Company (as treasury stock or

                                       2
<PAGE>

        otherwise) shall automatically be canceled and retired and shall cease
        to exist and no consideration shall be delivered in exchange therefor.

                (b) Consideration for Company Common Stock. Subject to Section
        1.10, each issued and outstanding share of Company Common Stock (other
        than Dissenting Shares and shares to be canceled in accordance with
        Section 1.6(a)) shall be converted into the right to receive a number of
        fully paid and nonassessable shares of common stock, par value $.001 per
        share, of Parent ("Parent Common Stock") equal to the Conversion Ratio
        (as defined below) (the "Merger Consideration"). The "Conversion Ratio"
        shall be equal to $1.00 divided by the Average Parent Stock Price (as
        defined below). The "Average Parent Stock Price" shall mean the closing
        sales price per share of Parent Common Stock as reported by The New York
        Stock Exchange Composite Tape for the twenty consecutive trading days
        (on which shares of Parent Common Stock are actually traded) immediately
        preceding the second Business Day prior to the Effective Time; provided,
        however, that if the foregoing amount is calculated to be less than $30,
        then the Average Parent Stock Price shall be $30; and provided further,
        that if the foregoing amount is calculated to be greater than $32.50,
        then the Average Parent Stock Price shall be $32.50. As of the Effective
        Time, all such shares of Company Common Stock shall no longer be
        outstanding and shall automatically be canceled and retired and shall
        cease to exist, and each holder of a certificate which, prior to the
        Effective Time, represented any such shares of Company Common Stock
        shall cease to have any rights with respect thereto, except the right to
        receive, upon surrender of such certificate in accordance with
        Section 2.2, the Merger Consideration in accordance with this
        Section 1.6.

                (c) Merger Sub Capital Stock. Each share of capital stock of
        Merger Sub issued and outstanding immediately prior to the Effective
        Time shall remain outstanding and shall be unchanged as a share of
        capital stock of the Surviving Corporation.

     Section 1.7. Adjustment of Conversion Number. In the event that pursuant to
a transaction announced after the date hereof and becoming effective prior to
the Effective Time (i) any distribution is made in respect of Parent Common
Stock other than a regular quarterly cash dividend or (ii) any stock dividend,
stock split, reclassification, recapitalization, combination or mandatory
exchange of shares occurs with respect to, or rights (other than non-mandatory
offers to exchange) are issued in respect of, Parent Common Stock, then, the
Conversion Ratio shall be adjusted accordingly.

     Section 1.8. No Further Ownership Rights in Company Common Stock. All
shares of Parent Common Stock issued upon the surrender for exchange of
certificates which immediately prior to the Effective Time represented
outstanding share of Company Common Stock ("Certificates") in accordance with
the terms hereof (including any cash paid pursuant to Sections 1.9 or 2.3) shall
be deemed to have been issued in full satisfaction of all rights pertaining to
such shares of Company Common Stock, and from and after the Effective Time there
shall be no further registration of transfers of the shares of Company Common
Stock which were outstanding immediately prior to the Effective Time. If, after
the Effective Time, Certificates are presented to the Surviving Corporation for
any reason, they shall be canceled and exchanged as provided in Article II.

                                       3
<PAGE>

     Section 1.9. No Fractional Shares. No certificate or scrip representing
fractional shares of Parent Common Stock shall be issued upon the surrender for
exchange of Certificates, and such fractional share interests will not entitle
the owner thereof to vote or to any other rights of a stockholder of Parent.
Notwithstanding any other provision of this Agreement, each holder of shares of
Company Common Stock exchanged pursuant to the Merger who would otherwise have
been entitled to receive a fraction of a share of Parent Common Stock (after
taking into account all Certificates delivered by such holder) shall receive, in
lieu thereof, cash (without interest) in an amount equal to such fractional part
of a share of Parent Common Stock multiplied by the Average Parent Stock Price.

     Section 1.10. Shares of Dissenting Shareholders. Notwithstanding anything
in this Agreement to the contrary, any shares of Company Common Stock that are
outstanding immediately prior to the Effective Time and have not been voted in
favor of the Merger and with respect to which appraisal rights shall have been
demanded and perfected in accordance with Section 1091 of the OGCA to the extent
applicable (collectively, the "Dissenting Shares") and not withdrawn shall not
be converted into or represent the right to receive the Merger Consideration,
but such shares shall become the right to receive such consideration as may be
determined to be due to holders of Dissenting Shares pursuant to the laws of the
State of Oklahoma unless and until the holder of such Dissenting Shares
withdraws his or her demand for such appraisal in accordance with the OGCA or
becomes ineligible for appraisal. If, after the Effective Time, any such holder
withdraws his or her demand for appraisal or becomes ineligible for appraisal
(through failure to perfect or otherwise), such Dissenting Shares shall
thereupon be deemed to have been converted into and to have become exchangeable
for, as of the Effective Time, the right to receive, without any interest
thereon, the consideration provided for in Section 1.6. The Company shall give
Parent prompt notice of any demands for appraisal for shares of Company Common
Stock received by the Company, and Parent shall have the right to direct all
proceedings, negotiations and actions taken by the Company in respect thereof.

     Section 1.11. Company Options. At the Effective Time, each unexpired and
unexercised outstanding option, whether or not then vested or exercisable in
accordance with its terms, to purchase shares of Company Common Stock (the
"Company Options") previously granted by the Company or its Subsidiaries shall
be canceled and converted into the right to receive from the Parent, within 10
days following the Effective Time, cash in an amount equal to the product of (a)
$1.00 minus the exercise price per share of such Company Option, times (b) the
number of shares of Common Stock which may be purchased upon exercise of such
Company Option (whether or not then exercisable). Prior to (but effective at)
the Effective Time, the Company shall (i) obtain any consents from all holders
of Company Options and (ii) make any amendments to the terms of such stock
option or compensation plans or arrangements that, in the case of either clause
(i) or (ii), are necessary to give effect to the transactions contemplated by
this Section 1.11. Immediately prior to the Effective Time, the Company shall
terminate all plans and other arrangements pursuant to which such Company
Options were granted (the "Company Stock Option Plans") effective as of the
Effective Time with no further liability to the Company.

                                       4

     Section 1.12. Tax Consequences. It is intended by the parties hereto that
the Merger shall constitute a "reorganization" within the meaning of Section
368(a) of the Code. The parties hereto hereby adopt this Agreement as a "plan of
reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the
United States Treasury Regulations.

                                  ARTICLE II.

                           EXCHANGE OF CERTIFICATES

     Section 2.1. Exchange Agent. As of the Effective Time, Parent shall deposit
with ChaseMellon Shareholder Services or such other bank or trust company as may
be designated by Parent and be reasonably acceptable to the Company (the
"Exchange Agent") for the benefit of the holders of shares of Company Common
Stock, for exchange or payment in accordance with this Section 2.1, through the
Exchange Agent, (i) certificates evidencing such number of shares of Parent
Common Stock equal to (x) the Merger Consideration multiplied by (y) the
aggregate number of shares of Company Common Stock which may be converted into
the right to receive Parent Common Stock in the Merger; and (ii) any cash
necessary to pay amounts due pursuant to Section 1.9 (such certificates for
shares of Parent Common Stock and such cash being hereinafter referred to as the
"Exchange Fund"). The Exchange Agent shall, pursuant to irrevocable instructions
in accordance with Articles I and II, deliver the Parent Common Stock and cash
contemplated to be issued pursuant to Sections 1.6(b) and 1.9 out of the
Exchange Fund. The Exchange Fund shall not be used for any other purpose. The
Exchange Agent shall invest any cash included in the Exchange Fund, as directed
by Parent, on a daily basis. Any interest and other income resulting from such
investments shall be paid to Parent.

     Section 2.2. Exchange and Payment Procedures. As soon as reasonably
practicable after the Effective Time, the Exchange Agent shall mail to each
holder of record of a Certificate or Certificates that were converted into the
right to receive shares of Parent Common Stock and cash pursuant to Sections
1.6(b) and 1.9, (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 proper delivery of the Certificates to the Exchange Agent, and which
shall be in such form and have such other provisions as Parent may reasonably
specify) and (ii) instructions for use in effecting the surrender of the
Certificates in exchange for shares of Parent Common Stock and cash. Upon
surrender of a Certificate for cancellation to the Exchange Agent together with
such letter of transmittal, duly executed and completed in accordance with the
instructions thereto, and such other documents as may reasonably be required by
the Exchange Agent, the holder of such Certificate shall be entitled to receive
in exchange therefor a certificate representing that number of whole shares of
Parent Common Stock and cash which such holder has the right to receive pursuant
to the provisions of Article I and this Article II and the Certificate so
surrendered shall forthwith be canceled. In the event of a transfer of ownership
of Company Common Stock that is not registered in the transfer records of the
Company, a certificate representing the proper number of shares of Parent Common
Stock may be issued, and cash, if any, pursuant to Sections 1.6(b) and 1.9 may
be paid, to a person other than the person in whose name the Certificate so
surrendered is registered if the Certificate representing such Company Common
Stock is presented to the Exchange Agent, accompanied by all documents required
to evidence and effect

                                       5
<PAGE>

such transfer and evidence that any applicable stock transfer taxes have been
paid. Until surrendered as contemplated by this Article II, each Certificate
shall be deemed at any time after the Effective Time to represent only the right
to receive upon surrender the certificate representing shares of Parent Common
Stock and cash as contemplated by Article I.

     Section 2.3. Distributions with Respect to Unexchanged Shares. No dividends
or other distributions declared or made after the Effective Time with respect to
Parent Common Stock with a record date after the Effective Time shall be paid to
the holder of any unsurrendered Certificate with respect to the shares of Parent
Common Stock to which such holder is entitled hereunder and no cash payment paid
to any such holder pursuant to Sections 1.6(b) and 1.9 until the holder of
record of such Certificate shall surrender such Certificate. Subject to the
effect of applicable laws, following surrender of any such Certificate, there
shall be given to the record holder of the certificates representing whole
shares of Parent Common Stock to which such holder is entitled hereunder,
without interest, (i) at the time of such surrender, a certificate representing
the number of whole shares of Parent Common Stock and the amount of cash, if
any, pursuant to Section 1.9 to which such holder is entitled pursuant to
Section 1.9 and the amount of dividends or other distributions with respect to
such whole shares of Parent Common Stock with a record date after the Effective
Time and a payment date prior to the date of issuance to such holder, and (ii)
at the appropriate payment date, the amount of dividends or other distributions
with a record date after the Effective Time but prior to surrender and a payment
date subsequent to surrender payable with respect to such whole shares of Parent
Common Stock.

     Section 2.4. Termination of Exchange Fund. Any portion of the Exchange Fund
which remains undistributed to the holders of Certificates for nine months after
the Effective Time shall be delivered to Parent, upon demand, and any
shareholders of the Company who have not previously complied with the provisions
of this Article II shall thereafter look only to Parent for payment of their
claim for Parent Common Stock and cash and any dividends or distributions with
respect to Parent Common Stock. Any portion of the Exchange Fund remaining
unclaimed by holders of Company Common Stock five years after the Effective Time
(or such earlier date immediately prior to such time as such portion would
otherwise escheat to or become property of any Governmental Entity) shall, to
the extent permitted by applicable law, become the property of Parent free and
clear of any claims or interest of any person previously entitled therein.

     Section 2.5. No Liability. To the fullest extent permitted by law, none of
Parent, Merger Sub, the Company or the Surviving Corporation shall be liable to
any holder of Company Common Stock or Parent Common Stock, as the case may be,
for any shares (or dividends or distributions with respect thereto) and/or cash
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law.

     Section 2.6. Lost Certificates. If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
Parent, the posting by such person of a bond in such reasonable amount as Parent
may direct as indemnity against any claim that may be made against it with
respect to such Certificate, the Exchange Agent will deliver in exchange for
such

                                       6
<PAGE>

lost, stolen or destroyed Certificate the shares of Parent Common Stock and cash
in accordance with this Agreement.

     Section 2.7. Withholding Rights. Parent and the Exchange Agent shall be
entitled to deduct and withhold from the consideration otherwise payable
pursuant to this Agreement to any holder of shares of Company Common Stock such
amounts as Parent or the Exchange Agent, as applicable, is required to deduct
and withhold with respect to the making of such payment under the Code, or any
provision of state, local or foreign Tax law. To the extent that amounts are so
withheld by Parent or the Exchange Agent, such withheld amounts shall be treated
for all purposes of this Agreement as having been paid to the holder of the
shares of Company Common Stock in respect of which such deduction and
withholding was made by such party.

     Section 2.8. Further Assurances. At and after the Effective Time, the
officers and directors of the Surviving Corporation will be authorized to
execute and deliver, in the name and on behalf of the Company or Merger Sub, any
deeds, bills of sale, assignments or assurances and to take and do, in the name
and on behalf of the Company or Merger Sub, any other actions and things to
vest, perfect or confirm of record or otherwise in the Surviving Corporation any
and all right, title and interest in, to and under any of the rights, properties
or assets acquired or to be acquired by the Surviving Corporation as a result
of, or in connection with, the Merger.

     Section 2.9. Stock Transfer Books. At the Effective Time, the stock
transfer books of the Company shall be closed and there shall be no further
registration of transfers of shares of Company Common Stock thereafter on the
records of the Company. From and after the Effective Time, the holders of
Certificates shall cease to have any rights with respect to such shares of
Company Common Stock formerly represented thereby, except as otherwise provided
herein or by law. On or after the Effective Time, any Certificates presented to
the Exchange Agent or Parent for any reason shall be converted into the Merger
Consideration with respect to the shares of Company Common Stock formerly
represented thereby.

     Section 2.10. Affiliates. Notwithstanding anything herein to the contrary,
Certificates surrendered for exchange by any Affiliate (as defined in Section
5.9) of the Company shall not be exchanged until Parent has received an
Affiliate Agreement (as defined in Section 5.9) from such Affiliate.

                                 ARTICLE III.

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company represents and warrants to Parent and Merger Sub that the
statements contained in this Article III are true and correct except as set
forth herein and in the disclosure schedule delivered by the Company to Parent
and Merger Sub on or before the date of this Agreement (the "Company Disclosure
Schedule").  The Company Disclosure Schedule shall be arranged in paragraphs
corresponding to the numbered and lettered paragraphs contained in this
Article III.

                                       7
<PAGE>

     Section 3.1. Organization of the Company and its Subsidiaries. Each of the
Company and its Subsidiaries (as defined below) is duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
organization and has all requisite corporate, partnership or limited liability
company power and authority to carry on its business as now being conducted and
as proposed to be conducted. Each of the Company and its Subsidiaries is duly
qualified or licensed to do business and is in good standing in each
jurisdiction in which the property owned, leased or operated by it or the nature
of the business conducted by it makes such qualification or licensing necessary,
except where the failure to be so qualified, licensed or in good standing,
individually or in the aggregate, could not be expected to have a material
adverse effect on the business, properties, financial condition or results of
operations of the Company and its Subsidiaries, taken as a whole (a "Company
Material Adverse Effect"). The Company has delivered to Parent a true and
correct copy of the Certificate of Incorporation and Bylaws of the Company and
each of its Subsidiaries, in each case as amended to date and each of such
documents is in full force and effect. Neither the Company nor any of its
Subsidiaries is in violation of any provision of any of such documents. The
respective organizational documents of the Company's Subsidiaries do not contain
any provision that would limit or otherwise restrict the ability of Parent or
the Surviving Corporation, following the Effective Time, from owning or
operating such Subsidiaries on the same basis as the Company. A true and
complete list of all of the Company's Subsidiaries, together with the
jurisdiction of incorporation of each such Subsidiary and the percentage of
ownership interest of the Company therein, is set forth in Section 3.1 of the
Company Disclosure Schedule. Neither the Company nor any of its Subsidiaries
directly or indirectly owns (other than ownership interests in the Company or in
one or more of its Subsidiaries) any equity or similar interest in, or any
interest convertible into or exchangeable or exercisable for, any corporation,
partnership, joint venture or other business association or entity. As used in
this Agreement, the word "Subsidiary" means, with respect to any party, any
corporation or other organization, whether incorporated or unincorporated, of
which (i) such party or any other Subsidiary of such party is a general partner
or member or (ii) at least twenty-five percent (25%) of the securities or other
interests having by their terms ordinary voting power to elect or select a
majority of the Board of Directors or other persons or entities performing
similar functions with respect to such corporation or other organization is
directly or indirectly owned or controlled by such party or by any one or more
of its Subsidiaries, or by such party and one or more of its Subsidiaries.

     Section 3.2.    Capitalization.

                (a) The authorized capital stock of the Company consists of
        60,000,000 shares of Company Common Stock and 1,000,000 shares of the
        Company's Preferred Stock, $1.00 par value per share ("Company Preferred
        Stock"). As of the date hereof, (i) 36,885,333 shares of Company Common

        knowledge, other notice to the effect that, or otherwise been advised
        that, it is not in or may not be in compliance with any Regulations, and
        neither the Company nor any of its Subsidiaries have any reason to

        likely to result in violations of any Regulations.

                (b) The Company and each of its Subsidiaries have all licenses,
        permits, authorizations and approvals issued by Governmental Entities

     Section 3.19.  Year 2000 Problem. The "Year 2000 Problem" (that is, the
risk that computer applications used by any person may be unable to recognize
and perform properly date-sensitive functions involving certain dates prior to

Material Adverse Effect.

     Section 3.20.  Opinion of Financial Advisor. The financial advisors of the
Company, Prudential Securities, delivered to the Company an opinion dated the
date of this Agreement to the effect that the Merger Consideration is fair to

any of their respective officers, directors or employees have employed any
broker, financial advisor or finder or incurred any liability for any brokerage
fees, commissions or finder's fees in connection with the transactions

Securities as its financial advisor, the arrangements with which have been
disclosed in writing to Parent and Merger Sub prior to, and will not be modified
subsequent to, the date of this Agreement.

     Section 3.22.  Transactions With Affiliates. Other than the transactions
contemplated by this Agreement and except to the extent disclosed in the Company
SEC Reports filed prior to the date hereof or as disclosed in Section 3.23 of
the Company Disclosure Schedule, there have been no transactions, agreements,
arrangements or understandings between the Company or any of its Subsidiaries,
on the one hand, and the Company's affiliates or other persons, on the other
hand, that would be required to be disclosed under Item 404 of Regulation S-K
under the Securities Act.

     Section 3.23. No Excess Parachute or Nondeductible Payments. Any amount
that could be received (whether in cash or property or the vesting of property)
as a result of any of the transactions contemplated by this Agreement by any
employee, officer or director of the Company or any of its affiliates who is a
"disqualified individual" (as such term is defined in proposed Treasury
Regulation Section 1.280G-1) under any employment, severance or termination
agreement, other compensation arrangement or Benefit Arrangement currently in
effect does not constitute an "excess parachute payment" (as such term is
defined in Section 280G(b)(1) of the Code and the proposed regulations
thereunder). Neither the Company nor any of its Subsidiaries is a party to any
agreement, contract or arrangement that could result, on account of the
transactions contemplated hereunder, individually or in the aggregate, in any
payment that would be nondeductible under Section 162(m) of the Code.

     Section 3.24.  State Anti-Takeover Statutes. The Board of Directors of the
Company has approved the terms of this Agreement and the Voting, Option and
Disposition Agreement and the consummation of the transactions contemplated
hereby and thereby, and such approvals are sufficient to render inapplicable to
the Merger and the other transactions contemplated by this Agreement and the
Voting, Option and Disposition Agreement the restrictions of Section 1090.3 of
the OGCA. No other "fair price," "moratorium," "control share acquisition" or
other similar anti-takeover statute or regulation applies or purports to apply
to the Merger, this Agreement, the

                                       24
<PAGE>

Voting, Option and Disposition Agreement or any of the transactions contemplated
by this Agreement or the Voting, Option and Disposition Agreement.

     Section 3.25. Accuracy of Information. No representation or warranty by
the Company contained in this Agreement or in any certificate to be furnished by
or on behalf of the Company or its Subsidiaries pursuant hereto contains or will
contain any untrue statement of a material fact or omits to state a material
fact necessary to make the statements contained herein or therein, in light of
the circumstances under which they were made, not misleading with respect to the
Company and its Subsidiaries as a whole or the transactions contemplated by this
Agreement.

     Section 3.26. Inventory. Except as set forth in Section 3.26 of the
Company Disclosure Schedule, (i) all items of the Company's inventory and

merchantable, for sale in the ordinary course of business at normal mark-ups,
(ii) none of such items of the Company's inventory is obsolete (except to the
extent accrued from the Company Balance Sheet) and (iii) each item of such
inventory reflected on the Company Balance Sheet and the books and records of
the Company is so reflected on the basis of a complete physical count and is
valued at the lower of cost or market in accordance with GAAP.

     Section 3.27. Customers and Suppliers. Except for matters that reasonably
could not be expected to have a Company Material Adverse Effect, no supplier or
customer of the Company has advised the Company formally or informally that such
customer or supplier intends to terminate, discontinue or substantially reduce
its business with the Company and the Company does not expect the occurrence of
the Effective Time to adversely affect such relationship.

        arrangement to do any of the foregoing, or to authorize, recommend,
        propose or announce an intention to do any of the foregoing.

     Section 5.2. Cooperation; Notice; Cure. Subject to compliance with
applicable law, from the date hereof until the Effective Time, the Company shall
confer on a regular basis with one or more representatives of Parent to report
on the general status of ongoing operations at the Company. Each of Parent and
the Company shall promptly notify the other in writing of, and will use all
commercially reasonable efforts to cure before the Closing Date, any event,
transaction or circumstance, as soon as practical after it becomes known to such
party, that causes or will cause any covenant or agreement of such party under
this Agreement to be breached or that renders or will render untrue any
representation or warranty of such party contained in this Agreement. No notice
given pursuant to this paragraph shall have any effect on the representations,
warranties, covenants or agreements contained in this Agreement for purposes of
determining satisfaction of any condition contained herein.

     Section 5.3.    No Solicitation

                (a) The Company shall not, directly or indirectly, through any
        officer, director, employee, financial advisor, representative or agent
        of such party (i) solicit, initiate, or encourage any inquiries or
        proposals that constitute, or could reasonably be expected to lead to, a
        proposal or offer for a merger, consolidation, business combination,
        recapitalization, sale of substantial assets, sale or acquisition of
        shares of capital stock (including, without limitation, by way of a
        tender offer) or similar transaction involving the Company or any of its
        subsidiaries, other than the transactions contemplated by this Agreement
        (any of the foregoing inquiries or proposals being referred to in this
        Agreement as an "Acquisition Proposal"), (ii) initiate or

                                       31
<PAGE>

        engage in negotiations or discussions with any person (or group of
        persons) other than the Parent or its respective affiliates (a "Third
        Party") concerning, or provide any non-public information to any person
        or entity relating to or in contemplation of, any Acquisition Proposal,
        or (iii) agree to or recommend any Acquisition Proposal; provided,
        however, that nothing contained in this Agreement shall prevent the
        Company or its Board of Directors from (A) furnishing non-public
        information to, or entering into discussions or negotiations with, any
        person or entity in connection with an unsolicited bona fide written
        Acquisition Proposal by such person or entity or modifying or
        withdrawing its recommendation with respect to the transactions
        contemplated hereby or recommending an unsolicited bona fide written
        Acquisition Proposal to the stockholders of the Company, if and only to
        the extent that (1) a Third Party has made a written proposal to the
        Board of Directors of the Company to consummate an Acquisition Proposal,
        which proposal identifies a price to be paid for the outstanding
        securities or substantially all of the assets of the Company, (2) the
        Board of Directors of the Company believes in good faith, after
        consultation with its financial advisors, that such Acquisition Proposal
        is reasonably capable of being completed on the terms proposed and
        would, if consummated, result in a transaction more favorable to the
        stockholders of such party than the transaction contemplated by this
        Agreement, (3) the Board of Directors of the Company determines in good
        faith based on the written advice of outside legal counsel, that such
        action is required for such Board of Directors to comply with its
        fiduciary duties to stockholders under applicable law, (4) the Company
        is not in breach of its obligations under this Section 5.3, and (5)
        prior to furnishing such non-public information to, or entering into
        discussions or negotiations with, such Third Party, the Board of
        Directors of the Company receives from such Third Party an executed
        confidentiality and standstill agreement with terms no less favorable to
        such party than those contained in the Confidentiality Agreement dated
        July 8, 1999 between the Parent and the Company (the "Confidentiality
        Agreement") (an Acquisition Proposal meeting the requirements of each of
        clauses (1) through (5) above is referred to as a "Superior Proposal");
        or (B) complying with Rule 14e-2 promulgated under the Exchange Act with
        regard to an Acquisition Proposal. The Company agrees not to release any
        Third Party from, or waive any provision of, any standstill agreement to
        which it is a party or any confidentiality agreement between it and
        another person who has made, or who may reasonably be considered likely
        to make, an Acquisition Proposal, unless the Board of Directors of the
        Company determines in good faith based on the written advice of outside
        legal counsel, that such action is required for the Board of Directors
        of the Company to comply with its fiduciary duties to stockholders under
        applicable law.

                (b) The Company shall notify the Parent immediately after
        receipt by the Company or any of its subsidiaries (or any of their
        advisors) of any Acquisition Proposal or any request for non-public
        information in connection with an Acquisition Proposal or for access to
        the properties, books or records of such party by any Third Party that
        informs the Company or any of its subsidiaries (or any of their
        advisors) that it is interested in making, considering making, or has
        made, an Acquisition Proposal. Such notice shall be made orally and in
        writing and shall indicate in reasonable detail the identity of the
        offeror and the terms and conditions of such proposal, inquiry or
        contact. The Company shall continue to keep the Parent informed, on a
        current basis, of the status of any such discussions or negotiations and
        the terms being discussed or negotiated. Notwithstanding the foregoing,
        the Company shall not accept or enter into any agreement concerning a
        Superior Proposal for a period of at least five business days after the

                                       32
<PAGE>

        Parent's receipt of the notification of the terms thereof pursuant the
        second preceding sentence, during which period the Parent shall be
        afforded the opportunity to beat or improve upon the terms and
        conditions contained in such Superior Proposal.

                (c) The Company has terminated any direct or indirect (through
        any officer, director, employee, financial advisor, representative or
        agent of such party) discussions or negotiations with, and the provision
        of information or data to, any person (other than the Parent) respecting
        an Acquisition Proposal.

     Section 5.4. Preparation of Proxy Statement/Registration; Company
Shareholder Meeting.

                (a) As promptly as practicable after the execution of this
        Agreement, Parent shall prepare and the Company shall cooperate
        therewith, and the Company shall file with the SEC, a proxy
        statement/prospectus (the "Proxy Statement") to be sent to the
        shareholders of the Company in connection with the Company Stockholders'
        Meeting to consider the Merger and the issuance of Parent Common Stock
        in connection therewith, and Parent shall prepare and file with the SEC
        a registration statement on Form S-4 pursuant to which the shares of
        Parent Common Stock to be issued in the Merger will be registered under
        the Securities Act (the "Registration Statement") and the Company shall
        cooperate therewith, in which the Proxy Statement will be included as a
        prospectus. Parent may delay the filing of the Registration Statement
        until after the Proxy Statement has been declared effective. Parent and
        the Company shall use reasonable best efforts to cause the Registration
        Statement to become effective as soon after filing as practicable. The
        Proxy Statement shall include the unanimous recommendation of the Board
        of Directors of the Company (with one director absent) in favor of this
        Agreement and the Merger unless the Board changes such recommendation
        pursuant to clause (e) below. Parent and the Company shall make all
        other necessary filings with respect to the Merger under the Securities
        Act and the Exchange Act and the rules and regulations thereunder. If at
        any time before the Effective Time any event relating to the Company or
        Parent, or any of its affiliates, officers, or directors, is discovered
        by the Company or Parent, respectively, that should be set forth in an
        amendment to the Registration Statement or a supplement to the Proxy
        Statement, such party shall promptly so inform the other.

                (b) The Company shall take all action necessary to cause the
        representation set forth in Section 3.16 to be true and correct at all
        applicable times with respect to each of the Proxy Statement and the
        Registration Statement.

                (c) Parent shall take all action necessary to cause the
        representation set forth in Section 4.5 to be true and correct at all
        applicable times with respect to each of the Proxy Statement and the
        Registration Statement.

                (d) As soon as reasonably practicable, the Company and Parent
        shall take all such actions as may be necessary to comply with state
        "blue sky" or securities laws in connection with the transactions
        contemplated by this Agreement.

                                       33
<PAGE>

                (e) The Company shall, as soon as practicable following the date
        of this Agreement, duly call, give notice of, convene and hold a meeting
        of its shareholders (the "Company Stockholders' Meeting") for the
        purpose of obtaining the Required Company Votes with respect to this
        Agreement. The Board of Directors of the Company shall unanimously
        declare advisable and recommend adoption of this Agreement by the
        stockholders of the Company and, upon Parent's request, reconfirm such
        recommendation (provided that the Board of Directors of the Company need
        not make or reconfirm such recommendation (1) (x) if at the time that it
        would otherwise be required to make or reconfirm such recommendation the
        Company is not then in breach of its obligations under Section 5.3 and
        (y) in such event, if and only to the extent that the Board of Directors
        of the Company concludes in good faith (after having consulted with and
        considered the advice of outside legal counsel) in connection with the
        receipt of a Superior Proposal that such action is necessary in order
        for its directors to comply with their respective fiduciary duties under
        applicable law, or (2) if no other Acquisition Proposal is pending or in
        Parent's reasonable judgment likely to become pending). Notwithstanding
        the foregoing, the Company shall use its best efforts to solicit such
        adoption, and the Company shall nevertheless submit this Agreement to
        its stockholders for consideration.

     Section 5.5. Access to Information. Upon reasonable notice, the Company
shall (and shall cause its Subsidiaries to) afford to the officers, employees,
accountants, counsel and other representatives of Parent, access, during normal
business hours during the period prior to the Effective Time, to all its
personnel, properties, books, contracts, commitments and records and, during
such period, the Company shall, and shall cause its Subsidiaries to, furnish
promptly to the other (a) copies of monthly financial reports and acquisition
related reports, (b) a copy of each report, schedule, registration statement and
other document filed or received by it during such period pursuant to the
requirements of federal securities laws and (c) all other information concerning
its business, properties and personnel as Parent may reasonably request. Parent
will hold any such information furnished to it by the Company which is nonpublic
in confidence in accordance with the Confidentiality Agreement. No information
or knowledge obtained in any investigation pursuant to this Section 5.5 shall
affect or be deemed to modify any representation or warranty contained in this
Agreement or the conditions to the obligations of the parties to consummate the
Merger.

     Section 5.6.    Legal Conditions to Merger.

                (a) The Company and Parent shall each use their best efforts to
        (i) take, or cause to be taken, all appropriate action, and do, or cause
        to be done, all things necessary and proper under applicable law to
        consummate and make effective the transactions contemplated hereby as
        promptly as practicable, (ii) obtain from any Governmental Entity or any
        other third party any consents, licenses, permits, waivers, approvals,
        authorizations, or orders required to be obtained or made by the Company
        or Parent or any of their Subsidiaries in connection with the
        authorization, execution and delivery of this Agreement and the
        consummation of the transactions contemplated hereby including, without
        limitation, the Merger, and (iii) as promptly as practicable, make all
        necessary filings, and thereafter make any other required submissions,
        with respect to this Agreement and the Merger required under (A) the
        Securities Act and the Exchange Act, and any other applicable federal or
        state securities laws, (B) the HSR Act and any

                                       34
<PAGE>

        related governmental request thereunder, and (C) any other applicable
        law; without limiting the foregoing, the parties shall undertake all
        reasonable efforts to cause to be filed all requisite filings under the
        HSR Act within 10 business days of the date of this Agreement. The
        Company and Parent shall cooperate with each other in connection with
        the making of all such filings, including providing copies of all such
        documents to the non-filing party and its advisors prior to filing and,
        if requested, to accept all reasonable additions, deletions or changes
        suggested in connection therewith. The Company and Parent shall use
        their best efforts to furnish to each other all information required for
        any application or other filing to be made pursuant to the rules and
        regulations of any applicable law (including all information required to
        be included in the Proxy Statement and the Registration Statement) in
        connection with the transactions contemplated by this Agreement.

                (b) Parent and the Company agree, and shall cause each of their
        respective Subsidiaries, to cooperate and to use their respective best
        efforts to obtain any government clearances required for Closing
        (including through compliance with the HSR Act), to respond to any
        government requests for information, and to contest and resist any
        action, including any legislative, administrative or judicial action,
        and to have vacated, lifted, reversed or overturned any decree,
        judgment, injunction or other order (whether temporary, preliminary or
        permanent) (an "Order") that restricts, prevents or prohibits the
        consummation of the Merger or any other transactions contemplated by
        this Agreement, including, without limitation, by vigorously pursuing
        all available avenues of administrative and judicial appeal and all
        available legislative action. The parties hereto will consult and
        cooperate with one another, and consider in good faith the views of one
        another, in connection with any analyses, appearances, presentations,
        memoranda, briefs, arguments, opinions and proposals made or submitted
        by or on behalf of any party hereto in connection with proceedings under
        or relating to the HSR Act or any other federal or state antitrust or
        fair trade law. Parent shall be entitled to direct any proceedings or
        negotiations with any Governmental Entity relating to any of the
        foregoing, provided that it shall afford the Company a reasonable
        opportunity to participate therein. Notwithstanding anything to the
        contrary in this Section 5.6, neither Parent nor the Company nor any of
        their respective Subsidiaries shall be required to take any action that
        would reasonably be expected to substantially impair the overall
        benefits expected, as of the date hereof, to be realized from the
        consummation of the Merger or the divestiture or holding separate of any
        assets or businesses.

                (c) Each of the Company and Parent shall give (or shall cause
        their respective Subsidiaries to give) any notices to third parties, and
        use, and cause their respective Subsidiaries to use, their best efforts
        to obtain any third party consents related to or required in connection
        with the Merger that are set forth on Schedule 5.6(c) (collectively, the
        "Required Consents").

     Section 5.7. Publicity. Parent and the Company shall agree on the form and
content of the initial press release regarding the transactions contemplated
hereby and thereafter shall consult with each other before issuing, and use all
reasonable efforts to agree upon, any press release or other public statement
with respect to any of the transactions contemplated hereby and shall not issue
any such press release or make any such public statement prior to such
consultation, except as may be required by law.

     Section 5.8. Tax-Free Reorganization Parent and the Company shall each use
their respective best efforts to cause the Merger to be treated as a
"reorganization" within the meaning of Section 368(a) of the Code.

     Section 5.9. Affiliate Agreements. Upon the execution of this Agreement,
the Company will provide Parent with a list of those persons who are, in the
Company's reasonable judgment, "affiliates" of the Company within the meaning of
Rule 145 (each such person who is an "affiliate" of the Company within the
meaning of Rule 145 is referred to as an "Affiliate") promulgated under the
Securities Act ("Rule 145"). The Company shall provide Parent such information
and documents as Parent shall reasonably request for purposes of reviewing such
list and shall notify Parent in writing regarding any change in the identity of
its Affiliates prior to the Closing Date. The Company shall use its best efforts
to deliver or cause to be delivered to Parent by August 15, 2000 (and in any
case prior to the Effective Time) from each of its Affiliates, an executed
Affiliate Agreement, in form and substance satisfactory to Parent (an "Affiliate
Agreement"). Parent shall be entitled to place appropriate legends on the
certificates evidencing any Parent Common Stock to be received by such
Affiliates of the Company pursuant to the terms of this Agreement, and to issue
appropriate stop transfer instructions to the transfer agent for the Parent
Common Stock, consistent with the terms of the Affiliate Agreements (provided
that such legends or stop transfer instructions shall be removed, one year after
the Effective Date, upon the request of any stockholder that is not then an
Affiliate of Parent).

     Section 5.10. NYSE Listing. Parent shall promptly prepare and submit to the
NYSE a listing application covering the shares of Parent Common Stock to be
issued in the Merger, and shall use all reasonable efforts to cause such shares
to be approved for listing on the NYSE, subject to official notice of issuance,
prior to the Effective Time.

     Section 5.11. Prudential Agreement. Parent, the Company and the Prudential
Insurance Company of America ("Prudential")shall enter into an agreement with
respect to the repayment of certain subordinated notes, on terms and conditions
satisfactory to each of the Parent, the Company and Prudential (the "Prudential
Agreement").

     Section 5.12.    Indemnification.

                (a) From and after the Effective Time, Parent agrees that it
        will, and will cause the Surviving Corporation to, indemnify and hold
        harmless each present and former director and officer of the Company
        (the "Indemnified Parties"), against any costs or expenses (including
        attorneys' fees), judgments, fines, losses, claims, damages, liabilities
        or amounts paid in settlement incurred in connection with any claim,
        action, suit, proceeding or investigation, whether civil, criminal,
        administrative or investigative, arising out of or pertaining to matters
        existing or occurring at or prior to the Effective Time, whether
        asserted or claimed prior to, at or after the Effective Time, to the
        fullest extent that the Company would have been permitted under Oklahoma
        law and its Certificate of Incorporation or Bylaws in effect on the date
        hereof to indemnify such Indemnified Party.

                (b) For a period of three years after the Effective Time, Parent
        shall maintain or shall cause the Surviving Corporation to maintain (to
        the extent available in the market) in

                                       36
<PAGE>

        effect a directors' and officers' liability insurance policy covering
        those persons who are currently covered by the Company's directors' and
        officers' liability insurance policy (copies of which have been
        heretofore delivered by the Company to Parent) with coverage in amount
        and scope at least as favorable as the Company's existing coverage;
        provided that in no event shall Parent or the Surviving Corporation be
        required to expend in the aggregate in excess of 150% of the annual
        premium currently paid by the Company for such coverage; and if such
        premium would at any time exceed 150% of the such amount, then Parent or
        the Surviving Corporation shall maintain insurance policies which
        provide the maximum and best coverage available at an annual premium
        equal to 150% of such amount.

                (c) The provisions of this Section 5.12 are intended to be an
        addition to the rights otherwise available to the current officers and
        directors of the Company by law, charter, statute, bylaw or agreement,
        and shall operate for the benefit of, and shall be enforceable by, each
        of the Indemnified Parties, their heirs and their representatives.

     Section 5.13. Letter of the Company's Accountants. The Company shall use
reasonable efforts to cause to be delivered to Parent and the Company a letter
of Arthur Andersen LLP, the Company's independent auditors, dated a date within
two business days before the date on which the Registration Statement shall
become effective and addressed to Parent, in form reasonably satisfactory to
Parent and customary in scope and substance for letters delivered by independent
public accountants in connection with registration statements similar to the
Registration Statement.

     Section 5.14. Stockholder Litigation. The Company shall give Parent the
reasonable opportunity to participate in the defense of any stockholder
litigation against the Company and its directors relating to the transactions
contemplated hereby.

continue the listing and quotation of Parent Common Stock and Company Common
Stock on the NYSE and the AMEX, respectively, during the term of this Agreement
though the Effective Time.

     Section 5.16. Employee Benefits. Parent and the Company agree that the
Company and the Surviving Corporation shall pay promptly or provide when due all
compensation and benefits required to be paid pursuant to the terms of any
Employee Plan or Other Benefit Obligation as disclosed to Parent as of the
Effective Time. The Company shall take all action necessary to terminate its
401(k) Plan (the "Company 401(k) Plan") in compliance with applicable law, no
later than immediately prior to the Effective Time. On or as soon as
administratively practicable following the Effective Time employees who were
participants in the Company 401(k) Plan shall be eligible to participate in the
401(k) Plan sponsored by Parent or one of its Subsidiaries ("Parent 401(k)
Plan"). At the election of participants, Parent 401(k) Plan shall accept
rollovers from the Company 401(k) Plan. Nothing herein shall require the
continued employment of any person. Years of service with the Company and its
Subsidiaries prior to the Effective Time shall be treated as service with the
Surviving Corporation or Parent for eligibility and vesting purposes and for
purposes of vacation and severance pay accruals, except to the extent such
treatment will result in the duplication of benefits.

        issued, promulgated, enforced or entered any order, executive order,

written notice by the terminating party to the other party), whether before or
after approval of the matters presented in connection with the Merger by the
stockholders of the Company:

                (a) by mutual written consent of the Company and Parent; or

                (b) by either Parent or the Company if the Merger shall not have
        been consummated by six months from signing (the "Outside Date"),
        provided that the right to terminate this Agreement under this Section
        7.1(b) shall not be available to any party whose failure to fulfill any
        obligation under this Agreement has been the cause of or resulted in the
        failure of the Merger to occur on or before such date); or

                (c) by either Parent or the Company if a court of competent
        jurisdiction or other Governmental Entity shall have issued a
        nonappealable final order, decree or ruling or taken any other
        nonappealable final action, in each case having the effect of
        permanently restraining, enjoining or otherwise prohibiting the Merger;
        or

                (d) by Parent or the Company, if, at the Company Stockholders'
        Meeting (including any adjournment or postponement), the requisite vote
        of the stockholders of the Company in favor of the approval and adoption
        of this Agreement and the Merger shall not have been obtained; or

                (e) By Parent if (i) the Board of Directors of the Company shall
        have withdrawn, or adversely modified, or failed (upon Parent's request)
        to reconfirm its recommendation of the Merger or this Agreement (or
        determined to do so); (ii) the Board of Directors of the Company shall
        have determined to recommend to the shareholders of the Company that
        they approve an Acquisition Proposal other than that contemplated by
        this Agreement or shall have determined to accept a Superior Proposal;
        (iii) a tender offer or exchange officer that, if successful, would
        result in any person or "group" becoming a "beneficial owner" (such
        terms having the meaning in this Agreement as is ascribed under
        Regulation 13D under the Exchange Act) of 20% or more of the outstanding
        shares of Company Common Stock is commenced (other than by Parent or an
        Affiliate of Parent) and the Board of Directors of the Company fails to
        recommend that the shareholders of the Company not tender their shares
        in such tender or exchange offer; (iv) any person (other than Parent or
        an Affiliate of Parent) or "group" becomes the "beneficial owner" of 20%

        any reason the Company fails to call or hold the Company Shareholders
        Meeting by the Outside Date; or

                (f) by the Company, prior to the Required Company Vote if, as a
        result of a Superior Proposal received by such party from a Third Party,
        the Board of Directors of the Company determines in good faith, based on
        written advice of outside legal counsel, that

                                       41
<PAGE>

        accepting such Superior Proposal is required for the Board of Directors
        of the Company to comply with its fiduciary duties to stockholders under
        applicable law; provided, however, that (i) no termination shall be
        effective pursuant to this Section 7.1(f) under circumstances in which a
        termination fee is payable by the Company pursuant to Section
        7.3(b)(iv), unless concurrently with such termination, such termination
        fee is paid in full by the Company in accordance with Section 7.3(b)(iv)
        and (ii) the Company's right to terminate under this paragraph (f) shall
        not be available if the Company has breached Section 5.3; or

                (g) by Parent or the Company, if there has been a breach of any
        representation, warranty, covenant or agreement on the part of the other
        party set forth in this Agreement, which breach will cause the
        conditions set forth in Section 6.2(a) or (b) (in the case of
        termination by the Company) or Section 6.3(a) or (b) (in the case of
        termination by Parent) not to be satisfied.

     Section 7.2. Effect of Termination. In the event of termination of this
Agreement as provided in Section 7.1, this Agreement shall immediately become
void and there shall be no liability or obligation on the part of Parent, Merger
Sub or the Company, or their respective officers, directors, stockholders or
Affiliates, except as set forth in Section 7.3 and Article VIII and except that

        Agreement; provided that this limitation shall not apply in the event of
        a willful breach of this Agreement by the Company or Parent.

                (d) Fees payable pursuant to Section 7.3(b)(iv) shall be paid
        concurrently with the event described in Section 7.3(b)(iv). Fees
        pursuant to Section 7.3(b)(i), (ii), (iii) or (v) shall be paid within
