     2.3 EFFECT OF THE MERGER. Upon the Effective Time, the separate existence
of Merger Sub shall cease and the Company, as the surviving corporation in the
Merger (the "SURVIVING CORPORATION"), shall continue its corporate existence
under the laws of the State of Oklahoma. The Merger shall have the effects
specified in this Agreement and the OGCA.

     shall be the directors and officers, respectively, of the Surviving
     Corporation from the Effective Time until their respective successors have

     Merger Sub Common Stock outstanding immediately prior to the Effective Time
     shall remain outstanding and continue as one share of capital stock of the
     Surviving Corporation, and each certificate evidencing ownership of any
     such shares shall continue to evidence ownership of the same number of
     shares of the capital stock of the Surviving Corporation.

          (b) COMPANY SECURITIES.

               (i) COMPANY COMMON STOCK. At the Effective Time, by virtue of the

          share of Company Common Stock that is issued and outstanding
          immediately prior to the Effective Time shall be converted into the
          right to receive the Per Share Amount of the Closing Date Merger
          Consideration. Each share of Company Common Stock, when so converted,
          shall automatically be cancelled and retired, shall cease to exist and

          this Section 2.5(b): (A) the provisions of any other plan, program or
          arrangement providing for the issuance or grant of any other interest
          in respect of the capital stock of the Company shall become null and

     Company Common Stock; (ii) Parent shall pay or cause to be paid to each
     Stockholder in whose name a Company Certificate shall have been registered,
     in exchange therefor, cash in an amount equal to the product of (A) the Per
     Share Amount of the difference between the Closing Date Merger
     Consideration and the Post Closing Escrow Fund, times (B) the number of
     shares of Company Common Stock represented by such Company Certificate
     (each Company Certificate so surrendered shall forthwith be cancelled); and

     N.A., as escrow agent ("ESCROW AGENT"), to be held for a period of one year
     following the date of this Agreement in an account created pursuant to the
     terms of that certain escrow agreement (the "ESCROW AGREEMENT"), in the
     form attached hereto as EXHIBIT A and the provisions of Section 2.11.

          (b) NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK. The Closing
     Date Merger Consideration paid upon the surrender for exchange of shares of
     Company 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 Company Common Stock. After the date three (3) days prior to the
     Effective Time, there shall be no further registration of transfers on the
     stock transfer books of the Surviving Corporation of the shares of Company
     Common Stock that were outstanding immediately prior to the Effective Time.

     Surviving Corporation for any reason, it shall be cancelled and exchanged
     as provided in this Section 2.6.

          (c) LOST, STOLEN, OR DESTROYED COMPANY CERTIFICATES. If any Company
     Certificate shall have been lost, stolen or destroyed, upon the making of
     an affidavit of that fact by the Person claiming such Company Certificate
     to be lost, stolen or destroyed and, if required by Parent, the written
     agreement by such Person in form and substance

                                       12
<PAGE>

     satisfactory to Parent to indemnify until the applicable statute of
     limitations expires Parent and the Surviving Corporation against any claim
     that may be made against it with respect to such Company Certificate,
     Parent shall pay to such holder, in exchange for such lost, stolen or
     destroyed Company Certificate the Closing Date Merger Consideration
     deliverable with respect thereto pursuant to this Agreement.

          (d) SEVERANCE PAYMENTS AND BROKERAGE FEES. Immediately prior to the
     Closing, the Company shall pay (subject to all applicable withholding taxes
     and in accordance with and to the extent then due) all severance and other
     amounts set forth in Section 3.11 of the DISCLOSURE SCHEDULE and all
     brokerage fees set forth in Section 3.20 of the DISCLOSURE SCHEDULE.

     2.7 CLOSING. The Closing shall take place on the Closing Date at such time
and place as is agreed upon by Parent and the Company.

     2.8 TAKING OF NECESSARY ACTION; FURTHER ACTION. Each of Parent, Merger Sub,
and the Company shall use all reasonable efforts to take all such actions as may
be necessary or appropriate in order to effectuate the Merger on or after
October 1, 2001, under the OGCA as promptly as commercially practicable. If, at
any time after the Effective Time, any further action is necessary or desirable
to carry out the purposes of this Agreement and to vest the Surviving
Corporation with full right, title and possession to all assets, property,
rights, privileges, powers and franchises of Merger Sub and the Company, the
present and future officers and directors of the Surviving Corporation are fully
authorized, in the name of the Surviving Corporation or otherwise, to take, and
shall take, all such lawful and necessary action.

     2.9 EARNEST MONEY. Contemporaneous with the execution of this Agreement,
Parent or Merger Sub shall deposit with Escrow Agent the amount of $3,750,000
(the "EARNEST MONEY"). In the event the Closing occurs, the Earnest Money shall
be returned to Parent or Merger Sub (with interest). If the Closing does not
occur, the Earnest Money shall be paid to the Company or returned to Parent or
Merger Sub in accordance with this Section 2.9. In the event Parent or Merger
Sub breaches this Agreement by failing or refusing to close the transaction
contemplated hereby on the Closing Date and each of the conditions contained in
Article 6 has been either fulfilled in all material respects or waived, the
Earnest Money (with interest) shall be paid to the Company as liquidated damages
in lieu of all other damages (and as the Company's sole remedy in such event).
The Parties hereby acknowledge that the extent of damages to the Company
occasioned by such failure or refusal by Parent or Merger Sub would be
impossible or extremely impractical to ascertain and that the amount of the
Earnest Money is a fair and reasonable estimate of such damages under the
circumstances. In the event the Closing does not occur and the Earnest Money is
not retained pursuant to the foregoing provisions of this Section 2.9, the
Earnest Money shall be returned to Parent or Merger Sub (with interest).

     2.10 EXCLUDED ASSETS. Except as set forth in Schedule 1.1B, prior to the
Closing, the Excluded Assets will be distributed by the Company to its
Stockholders or otherwise transferred to one or more of the Stockholders of the
Company or their nominee(s). None of the representations or warranties set forth
in this Agreement nor any of the other provisions of this Agreement shall be
applicable to the Excluded Assets.

                                       13
<PAGE>

     2.11 RELEASE FROM ESCROW. If no claim for indemnification is then pending
or unresolved, the Post Closing Escrow Fund shall terminate upon the expiration
of twelve months after the date of this Agreement. Within three days after such
termination, the Escrow Agent shall pay to each Stockholder an amount equal to
the Per Share Amount of the Post Closing Escrow Fund (as reduced by amounts
distributed to Parent in satisfaction of any claims for indemnification pursuant
to Article 8) times the number of shares of Company Common Stock surrendered by
each such Stockholder pursuant to Section 2.6(a).

     the Company included or reflected in the Ownership Interests. Each Oil and

     interest set forth in (or derived from) the Ownership Interests of all

     Gas Interest, and the portion of the costs and expenses of operation and
     development of such Oil and Gas Interest that is borne or to be borne by
     the Company is not greater than the undivided interest set forth in the
     Ownership Interests. No fact, circumstance or condition of the title to an
     Oil and Gas Interest of the Company shall be considered to effect a
     reduction in the value of such Oil and Gas Interest, unless due
     consideration has been given to (i) the length of time that such Oil and
     Gas Interest has been producing Hydrocarbon substances and has been
     credited to and accounted for by the Company and its predecessors in title,
     if any, and (ii) whether any such fact, circumstance or condition is of the

     Representatives and (ii) to which the Company has Knowledge.

          (d) The Company will not (and will cause the Company Representatives
     not to), and Parent will not (and will cause the Parent Representatives not
     to), use any information obtained pursuant to this Section 5.2 for any
     purpose unrelated to the consummation of the transactions contemplated by
     this Agreement.

     5.3 ADDITIONAL ARRANGEMENTS. Subject to the terms and conditions herein
provided, each of the Parties shall take, or cause to be taken, all action and
shall do, or cause to be done, all things necessary, appropriate or desirable
under any applicable laws and regulations or under applicable governing

this Agreement, including using reasonable efforts to obtain all necessary
waivers, consents and approvals and effecting all necessary registrations and
filings. Each of the Parties shall take, or cause to be taken, all action or
shall do, or cause to be done, all things necessary, appropriate or desirable to
cause the covenants and conditions applicable to the transactions contemplated
hereby to be performed or satisfied as soon as practicable. In addition, if any

<PAGE>

use reasonable efforts to have such order, decree, ruling or injunction or other
action declared ineffective as soon as practicable.

     5.4 PUBLIC ANNOUNCEMENTS; CONFIDENTIALITY. Prior to the Closing, the
Company and Parent shall consult with each other before any of them issues any
press release or otherwise makes any public statement with respect to the
transactions contemplated by this Agreement, and no Party shall issue any press
release or make any such public statement prior to obtaining the approval of the
other Parties which shall not be unreasonably withheld; provided, however, that
such approval shall not be required where such release or announcement is
required by applicable law; and provided further, that any Party may respond to
inquiries by the press or others regarding the transactions contemplated by this
Agreement, so long as such responses are consistent with such party's previously
issued press releases. The Company acknowledges that Parent's securities are
publicly traded and accordingly it has disclosure obligations under the Federal
securities laws. The Company will not use or disclose to any third party any
Parent Confidential Information. The Parties each acknowledge and agree that
non-public information concerning the progress of the transaction contemplated
by this Agreement is confidential information.

     5.5 NOTIFICATION OF CERTAIN MATTERS. Between the date hereof and the
Closing Date, the Company shall give prompt notice to Parent of: (a) any
representation or warranty contained in Article 3 being untrue or inaccurate
when made, (b) the occurrence of any event or development that would cause (or
could reasonably be expected to cause) any representation or warranty contained
in Article 3 to be untrue or inaccurate on the Closing Date, (c) any failure of
the Company to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by it hereunder, and/or (d) the Company's becoming
aware of any representation and warranty contained in Article 4 being or
becoming untrue or inaccurate when made or as of a later date. Parent shall give
prompt notice to the Company of: (w) any representation or warranty contained in
Article 4 being untrue or inaccurate when made, (x) the occurrence of any event
or development that would cause (or could reasonably be expected to cause) any
representation or warranty contained in Article 4 to be untrue or inaccurate on
the Closing Date, (y) any failure of Parent to comply with or satisfy any
covenant, condition, or agreement to be complied with or satisfied by it
hereunder, and/or (z) Parent's becoming aware of any representation and warranty
contained in Article 3 being or becoming untrue or inaccurate when made or as of
a later date. No disclosure by any party pursuant to this Section 5.5, however,
shall be deemed to amend or supplement the DISCLOSURE SCHEDULE or to prevent or
cure any misrepresentation, breach of warranty, or breach of covenant.

     5.6 PAYMENT OF EXPENSES. Each Party shall pay its own expenses incident to
preparing for, entering into and carrying out this Agreement and the
consummation of the transactions contemplated hereby, whether or not Closing
occurs.

     5.7 CONTINUATION OF THE COMPANY'S EXISTING INDEMNIFICATION OBLIGATIONS.
From and after the Closing, the Company or its successor shall indemnify and
hold harmless each Person who has been at any time prior to the Closing, an
officer, director or controlling stockholder of the Company (collectively, the
"COMPANY INDEMNIFIED PERSONS") but only to the extent that such Company
Indemnified Person was entitled to indemnification from the Company immediately
prior to the date hereof under applicable law or the certificate of
incorporation and/or bylaws of the Company. The procedures associated with such

                                       29
<PAGE>

indemnification shall be the same as those associated with the Company
Indemnified Persons' indemnification from the Company immediately prior to the
date hereof (provided, however, that Parent shall be under no obligation to
deposit trust funds pursuant to any "change-in-control" or similar provisions).
The provisions of this Section 5.7 are intended to be for the benefit of, and
shall be enforceable by, the Parties and each Company Indemnified Person and
their respective heirs and representatives.

     5.8 RESIGNATION OF DIRECTORS AND OFFICERS. Each director and officer of the
Company shall resign his or her position with the Company effective at Closing.

     5.9 TITLE AND ENVIRONMENTAL DEFECTS.

          (a) Parent may conduct, at its sole cost, such title examination or
     investigation, and other examinations and investigations, as it may in its
     sole discretion choose to conduct with respect to the Company's Oil and Gas
     Interests in order to determine whether any Title or Environmental Defects
     exist. Parent must deliver to the Company in writing on or before September
     8, 2001, at 5:00 p.m. C.D.T., a written notice specifying each defect
     associated with the Oil and Gas Interests of the Company that it asserts
     constitutes a violation of the representations set forth in Section 3.14 or
     3.17 (a "TITLE OR ENVIRONMENTAL DEFECT"), a description of each such Title
     or Environmental Defect, the amount of the adjustment to the Base Merger
     Consideration that it asserts based on such defect and its method of
     calculating such adjustment. If such notice is not timely submitted, Parent
     will be deemed to have waived its basis for a purchase price adjustment
     under this Section 5.9 based on a violation of the representations set
     forth in Section 3.14 or 3.17. For the purpose of determining an
     Environmental Defect under this Section 5.9 only, the representations and
     warranties set forth in Section 3.17 shall be deemed not to be qualified by
     the Knowledge of the Company.

          (b) Upon timely delivery of a notice under Section 5.9(a), Parent and
     the Company will in good faith negotiate the validity of the claim and the
     amount of any adjustment to the Base Merger Consideration using the
     following criteria:

               (i) No adjustment will be made to the Base Merger Consideration
          under this Section 5.9 except to the extent that the net total of all
          individual adjustments under this Section 5.9 exceed $250,000 in the
          aggregate; by way of example, if the net total of all individual
          adjustments under this Section 5.9 equals $300,000, then an adjustment
          of $50,000 shall, subject to Section 5.9(d), be made to the Base
          Merger Consideration.

               (ii) If the requested adjustment is based on the Company owning a
          net revenue interest for a well, unit rights or leasehold rights less
          than that shown in SCHEDULE 1.1A, then a downward adjustment shall be
          calculated by multiplying the Allocated Value set forth for such well,
          unit rights or leasehold rights on SCHEDULE 1.1A by a fraction (A) the
          numerator of which is an amount equal to the net revenue interest
          shown on SCHEDULE 1.1A for such well, unit rights or leasehold rights
          less the decimal share to which the Company would be entitled as a
          result of its ownership interest in such well, unit rights or
          leasehold rights which is unaffected by such Title Defect, and (B) the
          denominator of which is the net

                                       30
<PAGE>

          revenue interest shown for such well, unit rights or leasehold rights
          on SCHEDULE 1.1A. Any downward adjustments requested by Parent may be
          offset by upward adjustments if it is determined that the Company's
          net revenue interest for any other well, unit rights or leasehold
          rights shown on SCHEDULE 1.1A is greater than that shown on SCHEDULE
          1.1A.

               (iii) If the adjustment is based on the Company owning a working
          interest that is larger than the working interest shown on SCHEDULE
          1.1A, but without a proportionate increase in the Company's net
          revenue interest, then the adjustment is calculated by determining the
          effective net revenue interest that results from such larger working
          interest, determining what the net revenue interest would be using
          such effective net revenue interest and the working interest shown on
          SCHEDULE 1.1A and then calculating the adjustment in the manner set
          forth in clause (iii) preceding.

               (iv) If the adjustment is based on a Lien or other monetary
          charge upon an Oil and Gas Interest or a liability to remediate or
          otherwise cure an environmental defect related to an Oil and Gas
          Interest that is liquidated in amount, then the adjustment is the
          lesser of (A) the amount necessary to remove such Lien or other
          monetary charge from, or a liability to remediate or otherwise cure an
          environmental defect relating to, the affected Oil and Gas Interest,
          or (B) the Allocated Value of the affected Oil and Gas Interest.

               (v) If the adjustment is based on an obligation, burden or
          liability upon the affected Oil and Gas Interest for which Parent's
          economic detriment is not liquidated but can be estimated with
          reasonable certainty, then the adjustment is the amount necessary to
          compensate Parent at Closing for the adverse economic effect on the
          affected Oil and Gas Interest.

          (c) If the value of a Title or Environmental Defect and, consequently,
     the adjustment to the Base Merger Consideration cannot be determined based
     on the above criteria, or if the Parties cannot otherwise agree on the
     amount of an adjustment, the Company may convey the affected Oil and Gas
     Interest to another entity and reduce the Base Merger Consideration by the
     Allocated Value of such interest.

          (d) In the event that the aggregate potential adjustments to the Base
     Merger Consideration pursuant to this Section 5.9 could reduce the Base
     Merger Consideration by more than $2,000,000, either the Company or Parent
     may terminate this Agreement.

     5.10 ADJUSTMENT TO BASE MERGER CONSIDERATION.

          (a) The Base Merger Consideration will be adjusted (i) upward or
     downward, as applicable, by the Company's positive or negative Working
     Capital Adjustment as of the Closing Date, (ii) upward by an amount equal
     to all capital expenditures paid by the Company on or after July 17, 2001
     (which, if required under Section 5.1(l) to be approved by Parent, have
     been so approved), (iii) upward or downward, as applicable, as required by
     Section 5.9, (iv) downward by the amount of the severance payments
     described in Section 3.11 of the DISCLOSURE SCHEDULE, (v) downward by the
     amount of

                                       31
<PAGE>

     the brokerage fee described in Section 3.20 of the DISCLOSURE SCHEDULE, and
     (vi) downward by the estimated amount of all accrued but unpaid income
     taxes relating to the Company's fiscal year ending July 31, 2001, and
     relating to the sale of properties by Staghorn Resources, LLC in May, 2001,
     as reasonably determined by the Company. For purposes hereof, the "WORKING
     CAPITAL ADJUSTMENT" as of the Closing Date shall be equal to the Company's
     aggregate cash, accounts receivable and other current Assets as of such
     date, less the Company's accounts payable, and other current liabilities as
     of the Closing Date, as determined in accordance with the Company's usual
     basis of accounting, and less the amount of $4,527,000. Obligations of the
     Company for the payment of capital expenditures shall not be considered a
     current liability for the purpose of the Working Capital Adjustment.
     Accrued income taxes deducted from the Base Merger Consideration pursuant
     to subparagraph (vi) above shall not be considered a current liability for
     the purpose of the Working Capital Adjustment. The severance payments
     described in Section 3.11 of the DISCLOSURE SCHEDULE and the brokerage fee
     described in Section 3.20 of the DISCLOSURE SCHEDULE shall be paid prior to
     Closing by the Company and shall be deducted from the Company's cash for
     the purpose of the Working Capital Adjustment. Any excise tax due and
     payable on such severance payments shall be deducted for the purpose of the
     Working Capital Adjustment. The expenses of the audit described in Section
     5.12 shall not be deducted for the purpose of the Working Capital
     Adjustment.

          (b) Immediately prior to the Closing, the Company will determine the
     Working Capital Adjustment and will deliver to Parent a statement setting
     forth all of the adjustments to the Base Merger Consideration that are
     required pursuant to this Agreement. Payments at the Closing shall be on
     the basis of the Base Merger Consideration as so adjusted (the "CLOSING
     DATE MERGER CONSIDERATION").

     5.11 COMPANY EMPLOYEES. Following the Closing, Parent intends to retain
certain employees of the Company for the purpose of the transition of ownership.
Such employment shall continue at least through December 31, 2001. Such
employees who are employed on a full-time basis during such transition period by
the Surviving Corporation shall receive health insurance benefits equivalent to
the benefits now provided by the Company at the cost of the Surviving
Corporation. Prior to the Closing, the Company shall pay to all employees any
accrued vacation pay. Parent shall interview all personnel of the Company
interested in being employed by Parent in its Oklahoma City office. Parent shall
pay the reasonable moving expenses of any employee accepting a job with Parent.
The Parties acknowledge that, after the Effective Time, Parent may or may not,
in its sole discretion, offer employment to, or cause the Surviving Corporation
to continue the employment of, employees of the Company. In connection with the
Wood Oil Company 401(k) Plan, which shall have been terminated immediately prior
to the Closing, Parent agrees to obtain a favorable determination letter as to
the qualification of such plan as of the date of termination of such plan, to
administer such plan in compliance with its terms and applicable law, and to
make final distribution of the assets of such plan promptly after obtaining such
favorable determination letter. The Company shall prepay to General American
Life Insurance Company prior to Closing the amount of $2,500 for services
relating to termination of such 401(k) plan. The provisions of this Section 5.11
are intended to be for the benefit of, and shall be enforceable by, the Parties
and the employees of the Company covered by the Company Employee Benefit Plans
at the Effective Time and their respective heirs and representatives.

                                       32

     5.12 AUDIT. The Company shall use its Best Efforts to deliver to Parent on
or before October 1, 2001, audited financial statements of the Company comprised
of balance sheets as of the fiscal years ending July 31, 2000 and 2001 and the
related statements of operations and cash flows for the fiscal years ending July
31, 1999, 2000 and 2001, together with the unqualified audit reports of Ernst &
Young prepared in accordance with generally accepted accounting principles and
Regulation S-X of the Securities and Exchange Commission. Parent will be allowed
to monitor the audit proceedings. Parent shall bear the costs of obtaining such
audited financial statements. A failure to obtain such financial statements by
October 1, 2001, shall not be deemed to be a breach of this Agreement and shall
not result in a delay of the Closing.

     5.13 NONSOLICITATION. Following the execution of this Agreement, neither
the Company nor any of its Stockholders, representatives or advisors shall
directly or indirectly solicit or entertain offers from, provide information to,
negotiate with or in any manner encourage, discuss or consider any proposal of
any other Person relating to the acquisition of the capital stock of the
Company, its Assets or business, in whole or in part.

     5.14 BEST EFFORTS. Between the date of this Agreement and the Closing Date,
the Company and Parent will each use its Best Efforts to cause the conditions in
Article 6 to be satisfied.

     shall have been made or obtained (as the case may be), except where the
     failure to obtain such consents, approvals, permits and authorizations
     would not be reasonably likely to result in a Material Adverse Effect on
     Parent or to materially adversely affect the consummation of the
     transaction contemplated by this Agreement.

          (b) NO INJUNCTIONS OR RESTRAINTS. No temporary restraining order,
     preliminary or permanent injunction or other order issued by any court of
     competent jurisdiction or other legal restraint or prohibition preventing

     in effect; provided, however, that prior to invoking this condition, each
     Party shall use all reasonable efforts to have any such decree, ruling,
     injunction or order vacated, and, if necessary, the Closing shall be
     delayed for up to 60 days while such efforts are taking place.

                                   TERMINATION

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

          (b) By either Parent or the Company if (i) the Closing has not
     occurred by November 15, 2001 (provided, however, that the right to
     terminate this Agreement pursuant to this clause (i) shall not be available
     to any Party whose breach of any representation or warranty or failure to
     perform any covenant or agreement under this Agreement has been the cause

     ruling or taken any other action permanently restraining, enjoining or
     otherwise prohibiting Closing and such order, decree, ruling or other
     action shall have become final and nonappealable (provided, however, that
     the right to terminate this Agreement pursuant to this clause (ii) shall
     not be available to any Party until such Party has used all reasonable
     efforts to remove such injunction, order or decree);

          (c) By Parent if (i) the Company has failed to comply in any material
     respect with any of its covenants or agreements contained in this Agreement
     and such failure has

                                       35
<PAGE>

     not been, or cannot be, cured within a reasonable time after notice and
     demand for cure thereof; or (ii) Parent elects to exercise its right to
     terminate this Agreement pursuant to Section 5.9(d).

          (d) By the Company if (i) Parent or Merger Sub has failed to comply in

     or (ii) the Company elects to exercise its right to terminate this
     Agreement pursuant to Section 5.9(c) or (d).

          (e) (i) By Parent if any of the conditions in Sections 6.1 and 6.2 has
     not been satisfied as of the Closing Date or if satisfaction of such a
     condition is or becomes impossible (other than through the failure of
     Parent to comply with its obligations under this Agreement) and Parent has
     not waived such condition on or before the Closing Date; or (ii) by the

     7.2 EFFECT OF TERMINATION. If this Agreement is terminated by either Parent

contained therein), 5.2(b) (but only to the extent of the confidentiality and
indemnification provisions contained therein), 5.4 (with respect to the
confidentiality provisions contained therein), 5.6 and the Confidentiality
Agreement (which shall continue pursuant to their terms); provided, however,
that a termination of this Agreement shall not relieve any Party from any
liability for damages or specific performance incurred as a result of a breach
by such Party of its covenants, agreements or other obligations hereunder
occurring prior to such termination.

                                    ARTICLE 8

                                 INDEMNIFICATION

     8.1 SURVIVAL; RIGHT TO INDEMNIFICATION NOT AFFECTED BY KNOWLEDGE. The right
to indemnification, payment of Damages, or other remedy based on the
representations, warranties, covenants and obligations in this Agreement will
not be affected by any investigation conducted with respect to, or any Knowledge
acquired (or capable of being acquired), at any time, whether before or after
the execution and delivery of this Agreement or the Closing Date, with respect
to, the accuracy or inaccuracy of or compliance with, any such representation or
warranty, or the performance of or compliance with any such covenant or
obligation, and will not affect the right to indemnification, payment of
Damages, or other remedy based on such representations, warranties, covenants
and obligations; provided, however, Parent agrees to (a) notify the Company in
writing promptly after obtaining any Knowledge with respect to the inaccuracy or
noncompliance by the Company with any representation or warranty in this
Agreement or any

                                       36
<PAGE>

failure to perform a covenant or obligation in this Agreement, and (b) permit
the Company a reasonable period of time to cure any such inaccuracy or failure,
prior to asserting any rights of Parent to indemnification set forth in this
Agreement,

     8.2 INDEMNIFICATION AND PAYMENT OF DAMAGES BY THE STOCKHOLDERS. The
Stockholders will indemnify and hold harmless Parent and its directors,
officers, employees, agents and advisors, stockholders, controlling persons, and
Affiliates for, and will pay to such Indemnified Persons the amount of, any
loss, liability, obligation, debt, claim, damage, expense (including costs of
investigation and defense and reasonable attorneys' fees), whether or not
involving a Third-Party Claim (collectively "Damages"), arising, directly or
indirectly, from and in connection with:

          (a) any breach of any representation or warranty made by the Company
     in this Agreement (which representations and warranties shall each be read
     without giving effect to any update or supplement to the Schedules), the
     Schedules, the updates and supplements to the Schedules, or any other
     certificate or document delivered by the Company pursuant to this
     Agreement;

          (b) any estimate of taxes owed pursuant to Section 5.10(a)(vi) which
     is insufficient to cover the actual amount of such taxes; and

          (c) any breach of any covenant made by the Company in Section 5.1 of
     this Agreement.

     8.3 INDEMNIFICATION AND PAYMENT OF DAMAGES BY PARENT. Parent will indemnify
and hold harmless the Stockholders and will pay to the Stockholders the amount
of any Damages arising, directly or indirectly, from and in connection with (a)
any breach of any representation or warranty made by Parent in this Agreement or
in any certificate delivered by Parent pursuant to this Agreement, or (b) any
breach by Parent of any covenant or obligation of Parent in this Agreement.

     8.4 SURVIVAL.

          (a) If the Closing occurs, the representations and warranties of the
     Company and Parent will survive the Closing for a period of one year after
     the date of this Agreement.

          (b) The Stockholders shall have no liability under Section 8.2 unless,
     before the time period set forth in (a) above, Parent notifies the
     Stockholders of a claim specifying the factual basis for the claim in
     reasonable detail to the extent then known by Parent.

          If any claim for indemnification made is still pending or unresolved
     at the expiration of the survival period, such claim shall continue to be
     subject to the indemnification provisions of this Agreement.

          (c) If the Closing occurs, Parent will have no liability (for
     indemnification or otherwise) with respect to any representation, warranty,
     or covenant or obligation to be

                                       37
<PAGE>

     performed and complied with prior to the Closing Date, unless on or before
     one year after the date of this Agreement, the Stockholders notify Parent
     of a claim specifying the factual basis of that claim in reasonable detail
     to the extent then known by the Stockholders.

     8.5 PROCEDURE FOR INDEMNIFICATION - THIRD-PARTY CLAIMS.

          (a) Promptly after receipt by a Party entitled to indemnification
     under Section 8.2 or 8.3 (an "Indemnified Person") of notice of the
     commencement of any Proceeding against it, such Indemnified Person will, if
     a claim is to be made against any Party required to provide indemnification
     under Section 8.2 or 8.3 (an "Indemnifying Party"), give notice to the
     Indemnifying Party of the commencement of such claim, but the failure to
     notify the Indemnifying Party will not relieve the Indemnifying Party of
     any liability that it may have to any Indemnified Person, except to the
     extent that the Indemnifying Party demonstrates that the defense of such
     action is prejudiced by the Indemnified Person's failure to give such
     notice.

          (b) If any Proceeding referred to in Section 8.5(a) is brought against
     an Indemnified Person and it gives notice to the Indemnifying Party of the
     commencement of such Proceeding, the Indemnifying Party will be entitled to
     participate in such Proceeding and, to the extent that is wishes (unless
     (i) the Indemnifying Party is also a party to such Proceeding and the
     Indemnified Person determines in good faith that joint representation would
     be inappropriate, or (ii) the Indemnifying Party fails to provide
     reasonable assurance to the Indemnified Person of its financial capacity to
     defend such Proceeding and provide indemnification with respect to such
     Proceeding) to assume the defense of such Proceeding with counsel
     reasonably satisfactory to the Indemnified Person and, after written notice
     from the Indemnifying Party to the Indemnified Person of its election to
     assume the defense of such Proceeding and confirming its obligation to
     indemnify the Indemnified Person for the liability asserted in the claim,
     the Indemnifying Party will not, as long as it diligently conducts such
     defense, be liable to the Indemnified Person under this Article 8 for any
     fees of other counsel or any other expenses with respect to the defense of
     such Proceeding, in each case subsequently incurred by the Indemnified
     Person in connection with the defense of such Proceeding. If the
     Indemnifying Party assumes the defense of a Proceeding: (i) it will be
     conclusively established for purposes of this Agreement that the claims
     made in that Proceeding are within the scope of and subject to
     indemnification; (ii) no compromise or settlement of such claims may be
     effected by the Indemnifying Party without Indemnified Person's consent
     (which consent shall not be unreasonably withheld) unless (A) there is no
     finding or admission of any violation of Legal Requirements or any
     violation of the rights of any person and no effect on any other claims
     that may be made against the Indemnified Person, and (B) the sole relief
     provided is monetary damages that are paid in full by the Indemnifying
     Party; and (iii) the Indemnified Person will have no liability with respect
     to any compromise or settlement of such claims effected without its
     consent. If notice is given to an Indemnifying Party of the commencement of
     any Proceeding and the Indemnifying Party does not, within ten (10) days
     after the Indemnified Person's notice is given, give notice to the
     Indemnified Person of its election to assume the defense of such
     Proceeding, the Indemnifying Party will be bound by any determination made
     in such Proceeding or any compromise or settlement effected by the
     Indemnified Person,

                                       38
<PAGE>

     provided, however, the Indemnified Person may not compromise or settle such
     Proceeding without the prior consent of the Indemnifying Party (which
     consent will not be unreasonably withheld).

          (c) Notwithstanding the foregoing, if any Indemnified Person
     determines in good faith that there is a reasonable probability that a
     Proceeding may adversely affect it or its Affiliates other than as a result
     of monetary damages for which it would be entitled to indemnification under
     this Agreement, the Indemnified Person may, by notice to the Indemnifying
     Party, assume the exclusive right to defend, compromise, or settle such
     Proceeding, but the Indemnifying Party will not be bound by any compromise
     or settlement effected without its consent, which may not be unreasonably
     withheld.

     8.6 PROCEDURE FOR INDEMNIFICATION - OTHER CLAIMS. A claim for
indemnification for any matter not involving a Third-Party Claim may be asserted
by notice to the Party from whom indemnification is sought.

     8.7 LIMITS ON INDEMNITY OBLIGATIONS.

          (a) If the total amount of all Damages which the Indemnified Parties
     have the right to assert against the Stockholders under this Article 8 does
     not exceed $100,000 in the aggregate, then the Stockholders shall have no
     obligation under this Article 8 with respect to any such Damages. If the
     total amount of all Damages exceeds $100,000 in the aggregate, then the
     Stockholders' obligations under this Article 8 shall be limited to the
     amount by which the aggregate amount of all Damages exceeds $100,000.

          (b) Notwithstanding anything contained herein to the contrary, the
     sole recourse and exclusive remedy for the recovery of Damages from the
     Stockholders shall be against the Post Closing Escrow Fund. The
     Stockholders shall have no liability for Damages in excess of the amounts
     contained in the Post Closing Escrow Fund.

                                    ARTICLE 9

     9.3 COUNTERPARTS. This Agreement may be executed in two or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the Parties and delivered to the other Parties, it being understood that all
Parties need not sign the same counterpart.

     9.4 SEVERABILITY. Any term or provision of this Agreement that is invalid
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision shall be
interpreted to be only so broad as is enforceable.

     9.5 ENTIRE AGREEMENT; NO THIRD PARTY BENEFICIARIES. This Agreement
(together with the Confidentiality Agreement and the documents and instruments
delivered by the Parties

                                       40
<PAGE>

in connection with this Agreement): (a) constitutes the entire agreement and
supersedes all other prior agreements and understandings, both written and oral,
among the Parties with respect to the subject matter hereof; and (b) except as
provided in Sections 5.2, 5.7 and 5.11, is solely for the benefit of the Parties
and their respective successors, legal representatives and assigns and does not
confer on any other Person any rights or remedies hereunder.

     9.6 APPLICABLE LAW. This Agreement shall be governed in all respects,
including validity, interpretation and effect, by the laws of the State of
Oklahoma, regardless of the laws that might otherwise govern under applicable
principles of conflicts of laws thereof.

     9.7 NO REMEDY IN CERTAIN CIRCUMSTANCES. Each Party agrees that, should any
court or other competent authority hold any provision of this Agreement or part
hereof to be null, void or unenforceable, or order any Party to take any action
inconsistent herewith or not to take an action consistent herewith or required
hereby, the validity, legality and enforceability of the remaining provisions
and obligations contained or set forth herein shall not in any way be affected
or impaired thereby, unless the foregoing inconsistent action or the failure to
take an action constitutes a material breach of this Agreement or makes this
Agreement impossible to perform, in which case this Agreement shall terminate
pursuant to Article 7. Except as otherwise contemplated by this Agreement, to
the extent that a Party took an action inconsistent herewith or failed to take
action consistent herewith or required hereby pursuant to an order or judgment
of a court or other competent Governmental Authority, such Party shall not incur
any liability or obligation unless such Party breached its obligations under
Section 5.6 or did not in good faith seek to resist or object to the imposition
or entering of such order or judgment.

     9.8 ASSIGNMENT. Neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assigned by any of the Parties (whether by
operation of law or otherwise) without the prior written consent of the other
Parties, except that Parent may assign, in its sole discretion, its rights,
interests and obligations hereunder to any wholly-owned Subsidiary of Parent,
provided that Parent shall notify the Company of any such assignment and remain
responsible for all of its obligations hereunder. Subject to the preceding
sentence, this Agreement will be binding upon, inure to the benefit of and be
enforceable by the Parties and their respective successors and assigns.

     9.9 WAIVERS. At any time prior to the Closing, the Parties may, to the
extent legally allowed: (a) extend the time for the performance of any of the
obligations or other acts of the other Parties, (b) waive any inaccuracies in
the representations and warranties contained herein or in any document delivered
pursuant hereto, and (c) waive performance of any of the covenants or
agreements, or satisfaction of any of the conditions, contained herein. Any
agreement on the part of a Party to any such extension or waiver shall be valid
only if set forth in a written instrument signed on behalf of such Party. Except
as provided in this Agreement, no action taken pursuant to this Agreement,
including any investigation by or on behalf of any Party, shall be deemed to
constitute a waiver by the Party taking such action of compliance with any
representations, warranties, covenants or agreements contained in this
Agreement. The waiver by any Party of a breach of any provision hereof shall not
operate or be construed as a waiver of any prior or subsequent breach of the
same or any other provisions hereof.

     9.10 CONFIDENTIALITY AGREEMENT. The Confidentiality Agreement is hereby
incorporated herein by reference and shall constitute a part of this Agreement
for all purposes

                                       41
<PAGE>

and shall remain in full force and effect following the execution of this
Agreement until terminated in accordance with its terms; provided, however, to
the extent the terms of this Agreement conflict with the terms of the
Confidentiality Agreement, the terms of this Agreement shall control. Any and
all information received by Parent or Merger Sub pursuant to the terms and
provisions of this Agreement shall be governed by the applicable terms and
provisions of the Confidentiality Agreement.

     9.11 INCORPORATION BY REFERENCE. Exhibits and Schedules referred to herein
are attached to and by this reference incorporated herein for all purposes.

     9.12 COOPERATION AFTER CLOSING. Each Party shall, at any time and from time
to time after Closing, execute, acknowledge where appropriate and deliver such
further instruments and documents and take such other action as may be
reasonably requested by another Party in order to carry out the intent and
purpose of this Agreement.

     9.13 SPECIFIC PERFORMANCE; ATTORNEYS' FEES. The Parties recognize that if
the Company refuses to perform under the provisions of this Agreement, monetary
damages alone will not be adequate to compensate Parent for its injury. Parent
shall therefore be entitled, in addition to any other remedies that may be
available, to obtain specific performance of the terms of this Agreement. If any
action is brought by Parent to enforce this Agreement, the Company and the
Company's Stockholders shall waive the defense that there is an adequate remedy
at law. In the event of a default by either Party which results in the filing of
a lawsuit relating to such default, the prevailing Party in such lawsuit shall
be entitled to reimbursement from the non-prevailing Party of all reasonable
legal fees and expenses incurred by the prevailing Party.

     IN WITNESS WHEREOF, the Parties have caused this Agreement to be executed
by their duly authorized representatives, on the date first written above.
