At the Effective Time, the separate corporate existence of Sub shall cease and the Company shall continue as the surviving corporation (as such, the "Surviving Corporation") and a wholly-owned subsidiary of Parent. Section 1.03. Closing. Unless this Agreement shall have been terminated and the transactions contemplated hereby shall have been abandoned pursuant to Article VIII, the closing (the "Closing") of the Merger shall take place at the offices of Vinson & Elkins, L.L.P., 3700 Trammel Crow Center, 2001 Ross Avenue, Dallas, Texas 75201-2975, as soon as practicable, but in any event within two (2) business days (or up to ten (10) business days at the request of Parent), following the satisfaction or, to the extent permitted by Law (as defined in Section 3.05(a)), waiver of the conditions set forth in Article VII (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the fulfillment or, to the extent permitted by Law, waiver of those conditions), or at such other place, time and date as shall be agreed in writing between Parent and the Company. The date on which the Closing occurs is referred to in this Agreement as the "Closing Date." Section 1.04. Effective Time. Prior to the Closing, Parent shall prepare, and as promptly as possible on the Closing Date the parties shall cause the Merger to be consummated by filing with the Secretary of State of the State of Texas, articles of merger (the "Articles of Merger") in such form as is required by, and executed in accordance with, the relevant provisions of the TBCA and shall make all other filings or recordings required under the TBCA. The Merger shall become effective at such time as the Articles of Merger are duly filed with such Secretary of State of the State of Texas or at such later time as Parent and the Company shall agree and specify in the Articles of Merger (the time the Merger becomes effective being the "Effective Time"). Section 1.05. Effects. From and after the Effective Time, the Merger shall have the effects provided in Article 5.06A of the TBCA. At the Effective Time, the separate existence of Sub shall cease. All rights, titles and interests to all oil and gas assets and other property owned by the Company and Sub shall be allocated to and vested in the Surviving Corporation without reversion or impairment, without further act or deed, and without any transfer or assignment having occurred, but subject to any existing liens or other encumbrances thereon. All liabilities and obligations of the Company and Sub shall become liabilities and obligations of the Surviving Corporation. In addition, the Merger will have the effects set forth in Article II. Section 1.06. Articles of Incorporation and Bylaws.

(b) The Bylaws of the Company, as amended and in effect immediately prior to the Effective Time, shall be the Bylaws of the Surviving Corporation until thereafter changed or amended in accordance with the provisions thereof and the provisions of the Articles of Incorporation of the Surviving Corporation and applicable Law. Section 1.07. Directors and Officers. From and after the Effective Time, the officers of Sub shall be the officers of the Surviving Corporation and the directors of Sub shall be the directors of the Surviving 2 Corporation, in each case until their respective successors are duly elected and qualified. On or prior to the Closing Date, the Company shall deliver to Parent evidence satisfactory to Parent of the resignations of the officers and directors of the Company and its Subsidiaries (as defined in Section 3.02), such resignations to be effective as of the Effective Time. ARTICLE II EFFECT ON THE CAPITAL STOCK OF THE CONSTITUENT CORPORATIONS; SURRENDER OF CERTIFICATES Section 2.01. Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Sub or the Company or their respective shareholders: (a) Capital Stock of Sub. Each share of capital stock of Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one fully paid and nonassessable share of common stock, par value $0.10 per share, of the Surviving Corporation. (b) Cancellation of Treasury Stock and Parent-Owned Stock. Each share of Company Common Stock held in the treasury of the Company or issued and outstanding and owned, directly or indirectly, by Parent or any subsidiary of Parent or the Company, in each case immediately prior to the Effective Time shall automatically be canceled and retired and shall cease to exist, and no cash or other consideration shall be delivered or deliverable in respect thereto. (c) Conversion of Company Common Stock. (i) Subject to Sections 2.01(b) and 2.01(d), each share of Company Common Stock issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive an amount in cash equal to $17.53, without interest, less any required withholding taxes, upon surrender and exchange of the certificate representing such share. (ii) The cash payable upon the conversion of a share of Company Common Stock pursuant to this Section 2.01(c) is referred to as the "Merger Consideration." 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 formerly representing any such shares of Company Common Stock shall, subject to Section 2.01(d), cease to have any rights with respect thereto, except the right to receive the Merger Consideration, without interest less any required withholding taxes. (d) Dissenters' Rights. Notwithstanding anything in this Agreement to the contrary, shares of Company Common Stock that are issued and outstanding immediately prior to the Effective Time and that are held by any person who is entitled to dissent from and properly dissents from this Agreement pursuant to, and who complies in all respects with, Articles 5.11, 5.12 and 5.13 of the TBCA (the "Dissenters' Statute"), in each case to the extent applicable ("Dissent Shares"), shall not be converted into a right to receive the Merger Consideration as provided in Section 2.01(c), but rather the holders of Dissent Shares shall be entitled to the right 3 to receive payment of the fair value of such Dissent Shares in accordance with the Dissenters' Statute upon surrender of the certificate or certificates representing such Dissent Shares; provided, however, that if any such holder shall fail to perfect or otherwise shall effectively waive, withdraw or lose the right to receive payment of the fair value under the Dissenters' Statute, then the right of such holder to be paid the fair value of such holder's Dissent Shares shall cease and such Dissent Shares shall be deemed to have been converted as of the Effective Time into the right to receive the Merger Consideration, without interest less any required withholding taxes, as provided in Section 2.01(c). The Company shall give prompt notice to Parent of any objections or demands received by the Company for payment of the fair value of Company Common Stock pursuant to the Dissenters' Statute, and Parent shall have the right to direct all negotiations and proceedings with respect to such objections or demands. Neither the Company nor the Surviving Corporation shall, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such objections or demands, or agree to do any of the foregoing. Section 2.02. Surrender of Certificates; Payment for Shares. (a) Paying Agent. Prior to the Effective Time, Parent shall select a bank or trust company reasonably acceptable to the Company to act as paying agent (the "Paying Agent") for the payment of the Merger Consideration upon surrender of Certificates (as defined in Section 2.02(b)). At or prior to the Closing, Parent shall deposit with the Paying Agent for the benefit of the holders of shares of Company Common Stock the aggregate amount of the Merger Consideration payable in connection with the Merger (collectively, the "Exchange Fund"). The expenses of the Paying Agent shall not be paid from the Exchange Fund, but shall be paid directly by the Surviving Corporation or Parent. The Paying Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration in exchange for surrendered Certificates pursuant to this Section 2.02 out of the Exchange Fund. Except as contemplated by Section 2.02(d), the Exchange Fund shall not be used for any other purpose. (b) Surrender and Payment Procedure. Promptly after the Effective Time, except as otherwise provided in the immediately succeeding sentence, Parent shall cause the Paying Agent to send to each holder of record of a certificate or certificates that immediately prior to the Effective Time represented outstanding shares of Company Common Stock whose shares were converted into the right to receive the Merger Consideration pursuant to Section 2.01(c) (the "Certificates"), (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent and shall be in a form and have such other customary provisions as Parent may reasonably specify and that are reasonably acceptable to the Company) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for payment of the Merger Consideration. At least ten (10) days prior to the anticipated Closing Date, Parent shall make available to the Company a sufficient number of copies of the letter of transmittal and instructions so that the Company can provide them to its shareholders in advance of the Closing in order to permit shareholders, acting through the Company, to deliver their executed letters of transmittal and to surrender their Certificates to the Parent at the Closing, and the Paying Agent will not be required to send a letter of transmittal and instructions in accordance with the immediately preceding sentence to any shareholders who so deliver their letters of transmittal and surrender their Certificates at the Closing. Upon surrender of a Certificate for cancellation to the Parent or the Paying Agent, together with such letter of transmittal, duly executed, and such 4 other documents as may reasonably be required pursuant to such instructions, the holder of such Certificate shall be entitled to receive in exchange therefor cash in an amount equal to the product of (A) the number of shares of Company Common Stock theretofore represented by such Certificate and (B) the Merger Consideration, less any applicable withholding taxes, 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, payment may be made to a person other than the person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment shall pay any transfer or other taxes required by reason of the payment to a person other than the registered holder of such Certificate or establish to the satisfaction of Parent that such tax has been paid or is not applicable. No interest shall be paid or shall accrue on the cash payable upon surrender of any Certificate. (c) No Further Ownership Rights in Company Common Stock; Transfer Books. The Merger Consideration paid in accordance with the terms of this Article II upon conversion of any shares of Company Common Stock shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Company Common Stock. After the Effective Time, there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificates are presented to the Surviving Corporation or the Paying Agent for any reason, they shall be canceled upon payment of the Merger Consideration as provided in this Article II. (d) Termination of Exchange Fund; Investment of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the former holders of shares of Company Common Stock (who held shares immediately prior to the Effective Time) on the earlier of (i) the first anniversary of the Effective Time and (ii) any date at least ninety (90) days after the Effective Time if the balance of funds in the Exchange Fund is less than $10 million, shall be returned to the Parent, upon demand, and any such former holder of shares of Company Common Stock who has not theretofore complied with this Article II shall thereafter look only to the Parent, as a general creditor thereof, for payment of such holder's claim for the Merger Consideration. The Paying Agent shall invest any cash included in the Exchange Fund, as directed by Parent, on a daily basis. The Exchange Fund may be invested only in short-term deposits with a federally insured bank or savings and loan association having a net worth of at least $500 million or in money market funds that only invest in securities rated A or better by Standard & Poor's or U.S. government securities. Any interest and other income resulting from such investments shall be Parent's property and shall be paid to Parent upon request; provided that any losses, expenses, fees and commissions arising therefrom shall be borne by Parent and not by any such former holder of shares of Company Common Stock. (e) No Liability. None of Parent, Sub, the Company, the Surviving Corporation or the Paying Agent shall be liable to any person in respect of any payments or distributions payable from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificate shall not have been surrendered prior to seven years after the Effective Time (or immediately prior to such earlier date on which any Merger Consideration would otherwise escheat to or become the property of any governmental body or authority), any such Merger Consideration, to the extent permitted by 5 applicable Law, shall become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto. (f) Withholding Rights. Parent or the Surviving Corporation shall be entitled to deduct and withhold, or cause the Paying Agent to deduct and withhold, from the Merger Consideration otherwise payable to any former holder of shares of Company Common Stock (who held shares immediately prior to the Effective Time) pursuant to this Agreement, such amounts as may be required to be deducted and withheld with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the "Code"), or under any provision of state, local or foreign tax Law. To the extent that amounts are so deducted and withheld by Parent or the Surviving Corporation, such deducted and withheld amounts shall be treated for all purposes of this Agreement as having been paid to such former holder of the shares of Company Common Stock in respect of which such deduction and withholding was made by Parent or the Surviving Corporation. (g) 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 such person agreeing to indemnify the Surviving Corporation against any claim that may be made against Parent or the Surviving Corporation with respect to such Certificate (unless such Certificate represents more than 1,000 shares, in which case only upon the posting by such person of a bond in the amount of 3.0% of the Merger Consideration attributable to such lost Certificates, the Paying Agent will pay, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration to be paid in respect of the shares of Company Common Stock formerly represented by such Certificate, as contemplated by this Article II.

(a) Schedule 3.10(a) of the Company Disclosure Letter contains a list of all "employee pension benefit plans" (as defined in Section 3(2) of the Employee Retirement Income Security Act of 1974, as amended ("ERISA")) (sometimes referred to herein as "Company Pension Plans"), "employee welfare benefit plans" (as defined in Section 3(1) of ERISA) and all other Company Benefit Plans and Company Benefit Agreements (i) for which the Company has any obligation or liability and (ii) which the Company has maintained, or contributed to, or to which the Company is a party, for the benefit of any current or former employees, officers or directors of the Company, which has been as maintained or contributed to by the Company within six years prior to the Effective Time. The Company has made available to Parent true, complete and correct copies of (i) each Company Benefit Plan and Company Benefit Agreement including all amendments thereto (or, in the case of any unwritten Company Benefit Plan or Company Benefit Agreement, a description thereof), (ii) the most recent annual report on Form 5500 filed with the Internal Revenue Service with respect to each Company Benefit Plan (if any such report was required), (iii) the most recent summary plan description for each Company Benefit Plan for which such summary plan description is required, (iv) each trust agreement and group annuity contract relating to any Company Benefit Plan and (v) each employment and consulting agreement to which the Company is a party or is bound. (b) Each Company Pension Plan has received a favorable opinion, advisory, notification or determination letter from the Internal Revenue Service to the effect that such Company Pension Plan (and the underlying prototype or model document) is qualified in form under Sections 401(a) and 501(a), respectively, of the Code, and no such opinion, advisory, notification or determination letter has been revoked nor, to the knowledge of the Company, has revocation been threatened, nor except as required to comply with applicable Law or to the knowledge of the Company, has any such Company Pension Plan been amended since the date of its most recent opinion, advisory, notification or determination letter or application therefor in any respect that would materially adversely affect its qualification. The Company has substantially complied with all obligations, whether by operation of law or contract, including reporting and disclosure requirements, relating to the Company Benefit Plans or Company Benefit Agreements. There is no material pending or, to the knowledge of the Company, threatened litigation relating to the Company Benefit Plans. There are no matters, to the knowledge of the Company, pending before the Internal Revenue Service, the Department of Labor, the Pension Benefit Guaranty Corporation or any other Governmental Entity with respect to any Company Benefit Plan. (c) No Company Pension Plan that is a defined benefit plan subject to Title IV of ERISA other than any Company Pension Plan that is a "multiemployer plan" within the meaning of Section 4001(a)(3) of ERISA (a "Company Multiemployer Pension Plan"), had, as of the respective last annual valuation date for each such Company Pension Plan, any "unfunded benefit liabilities" (as such term is defined in Section 4001(a)(18) of ERISA), based on reasonable actuarial assumptions that have been furnished to Parent by the actuary for such 13 Company Pension Plan, and there has been no material adverse change in the financial condition of any Company Pension Plan since its last such annual valuation date. Except for premiums due under Section 4007 of ERISA, no liability under Subtitle C or D of Title IV of ERISA has, in the six years before the Effective Time, been or is expected to be incurred by the Company with respect to any ongoing, frozen or terminated Company Pension Plan that is a "single-employer plan," within the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by it, or the single-employer plan of any entity which is considered one employer with the Company under Section 4001(b) of ERISA or Section 414 of the Code (an "ERISA Affiliate"), which has been maintained or contributed to by such ERISA Affiliate within six years prior to the Effective Time (an "ERISA Affiliate Pension Plan"). None of the Company, any officer of the Company or any of the Company Benefit Plans which are subject to ERISA, including the Company Pension Plans, any trusts created thereunder, or, to the knowledge of the Company, any trustee or administrator thereof, has engaged in a "prohibited transaction" (as such term is defined in Section 406 of ERISA or Section 4975 of the Code) or any other breach of fiduciary responsibility that subjects the Company or any officer of the Company to any material tax or penalty on prohibited transactions imposed by such Section 4975 or to any material liability under Section 502(i) or 502(l) of ERISA. In the six years before the Effective Time, none of such Company Benefit Plans which are single-employer plans and their corresponding trusts has been terminated, nor has there been any "reportable event" (as that term is defined in Section 4043 of ERISA) for which the 30-day reporting requirement has not been waived with respect to any Company Benefit Plan, and no notice of a reportable event will be required to be filed in connection with the Merger. Neither the Company nor any ERISA Affiliate has incurred a "complete withdrawal" or a "partial withdrawal" (as such terms are defined in Sections 4203 and 4205, respectively, of ERISA) during the last six years with respect to any Company Multiemployer Pension Plan or any Multiemployer plan which has been maintained or contributed to by such ERISA Affiliate within six years prior to the Effective Time. As to each Company Multiemployer Pension Plan, Schedule 3.10(c) of the Company Disclosure Letter accurately describes the withdrawal liability which would be owed by the Company if the Company ceased contributing thereto as of the Effective Time. All contributions and premiums which are due and payable under the terms of any Company Benefit Plan and the provisions of the Code, ERISA and other applicable law as of the date hereof have been timely made or have been reflected on the most recent balance sheet of the Company furnished to Parent. Neither any Company Pension Plan nor any ERISA Affiliate Pension Plan has an "accumulated funding deficiency" (as such term is defined in Section 302 of ERISA or Section 412 of the Code), whether or not waived, and all contributions required by Section 302 of ERISA and Section 412 of the Code have been timely made thereto. (d) With respect to any Company Benefit Plan that is an employee welfare benefit plan, (i) no such Company Benefit Plan is funded through a "welfare benefit fund" (as such term is defined in Section 419(e) of the Code), (ii) each such Company Benefit Plan that is a "group health plan" (as such term is defined in Section 5000(b)(1) of the Code) complies substantially with the applicable requirements of Section 4980B(f) of the Code and (iii) each such Company Benefit Plan (including any such Company Benefit Plan covering retirees or other former employees) may be amended or terminated without material liability to the Company on or at any time after the Effective Time. Except as may be required by Section 4980B(f) of the Code, or applicable state health continuation laws, the Company has no obligations for retiree health and life benefits under any Company Benefit Plan or Company Benefit Agreement. 14 (e) The consummation of the Merger will not (x) entitle any employee, officer or director of the Company to severance pay or an election to terminate and receive severance pay, (y) accelerate the time of payment or vesting or trigger any payment or funding (through a grantor trust or otherwise) of compensation or benefits under, increase the amount payable or trigger any other material obligation pursuant to, any of the Company Benefit Plans or Company Benefit Agreements or (z) result in any breach or violation of, or a default under, any of the Company Benefit Plans or Company Benefit Agreements. (f) Other than payments that may be made to the persons and in the amounts listed in Schedule 3.10(f) of the Company Disclosure Letter, (i) any amount or economic benefit that is received or owed (whether in cash or property or the vesting of property) under any Company Benefit Plan or Company Benefit Agreement or otherwise as a result of the Merger or, to the Company's knowledge, any other event prior to the Effective Time (including upon, as a result of or in connection with a termination of employment on or following the Effective Time), 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) will not be characterized as an "excess parachute payment" (as defined in Section 280G(b)(1) of the Code), and (ii) no disqualified individual is entitled to receive any additional payment from the Company or any other person under any Company Benefit Plan or Company Benefit Agreement or otherwise as a result of the Merger in the event that the excise tax under Section 4999 of the Code is imposed on such disqualified individual. Section 3.11. Litigation. There is no suit, action, proceeding or investigation pending against, or to the knowledge of the Company threatened against, the Company or any of the Company's properties or rights before any arbitrator, court or other Governmental Entity that, individually or in the aggregate, would reasonably be expected to have a Company Material Adverse Effect. There are no suits, claims, actions, proceedings or investigations pending or, to the knowledge of the Company, threatened, seeking to prevent, hinder, modify or challenge the transactions contemplated by this Agreement. The Company is not subject to any outstanding Judgment against the Company or naming the Company as a party that, individually or in the aggregate, would reasonably be expected to have a Company Material Adverse Effect. Section 3.12. Compliance With Applicable Laws. (a) The Company is, and the Company's operations have been conducted, in compliance with all applicable Laws, except for such failures to comply as, individually or in the aggregate, would not have a Company Material Adverse Effect. The Company has not received any written notice: (i) of any administrative, civil or criminal investigation or audit (other than Tax or government royalty audits) by any Governmental Entity relating to the Company or (ii) during the past two years, from any Governmental Entity alleging that the Company is not in compliance in any material respect with any applicable Law that has not otherwise been cured to the satisfaction of such Governmental Entity. (b) The Company has in full force and effect all approvals, authorizations, certificates, filings, franchises, licenses, notices, permits, exemptions, exceptions, registrations and rights of or with all Governmental Entities ("Permits") necessary for the Company to own, 15 lease or otherwise hold and to operate the Company's properties and assets and to carry on the Company's business and operations as now conducted, except for the failure to have such Permits that, individually or in the aggregate, has not had and would not have a Company Material Adverse Effect. There have occurred no defaults under, or violations of, any such Permit, except for such defaults and violations that, individually and in the aggregate, have not had and would not reasonably be expected to have a Company Material Adverse Effect. There is no action, proceeding or investigation pending or to the knowledge of the Company, threatened, that could reasonably be expected to result in suspension, revocation or cancellation of any Permits. The Merger, in and of itself, would not cause the revocation or cancellation of any such Permit that, individually or in the aggregate, would reasonably be expected to have a Company Material Adverse Effect.

(b) Nothing in this Agreement shall require Parent or Sub to agree to, or permit the Company to agree to, the imposition of conditions, the payment of any material amounts or any requirement of divestiture to obtain any approval or consent, and in no event shall any party take, or be required to take, any action that would or could reasonably be expected to have a Company Material Adverse Effect. (c) The Company shall give prompt notice to Parent, and Parent or Sub shall give prompt notice to the Company, of (i) any representation or warranty made by it contained in this Agreement becoming untrue or inaccurate or any event or condition that could reasonably be expected to cause any representation or warranty made by it not to be true and correct at the Effective Time, (ii) the failure by it to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, (iii) any notice or other communication it receives from any person alleging that the consent of such person is or may be required in connection with the Merger, (iv) any notice or other communication it receives from any Governmental Entity in connection with the Merger, or (v) any action, suit, claim, investigation or proceeding commenced or, to its knowledge, threatened against, relating to or involving or otherwise affecting it that, if pending on the date of this Agreement, would have been required to have been disclosed pursuant to Section 3.11 or 4.07, as applicable, or that relate to the consummation of the Merger; provided, however, that no 30 such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement. Section 6.04. Stock Options. (a) At the Effective Time, each holder (an "Optionholder") of a then outstanding Company Stock Option (whether or not vested or exercisable) shall be entitled to receive from the Company, in cancellation of such Company Stock Option, for each share of Company Common Stock subject to such Company Stock Option, an amount (subject to any applicable withholding tax) in cash equal to the excess, if any, of the Merger Consideration over the per share exercise price of such Company Stock Option (such amount being hereinafter referred to as, the "Option Consideration"). Prior to the Effective Time, the Company shall use commercially reasonable best efforts to obtain an option cancellation agreement (in form reasonably satisfactory to Parent) executed by each such Optionholder that requires the cancellation of the Company Stock Options of such Optionholder in exchange for receipt by the Optionholder of the Option Consideration ("Option Cancellation Agreement")(or a written release of the Optionholder's rights under any Company Stock Option in form reasonably satisfactory to Parent). (b) All amounts payable to each Optionholder pursuant to this Section 6.04 shall be subject to any required withholding of Taxes and shall be paid as soon as practicable, but in any event within seven (7) days, following the later of the Effective Time and delivery by the Optionholder of his or her executed Option Cancellation Agreement (or a written release of the Optionholder's rights under any Company Stock Options in form reasonably satisfactory to the Parent) without interest. The cancellation of a Company Stock Option in exchange for the cash payment described in this Section 6.04 shall be deemed a release of any and all rights the holder had or may have had in respect thereof. (c) In this Agreement: "Company Stock Option" means any option to purchase Company Common Stock granted under any of the Company Stock Plans. "Company Stock Plans" means the Company's (i) 1998 Omnibus Stock and Incentive Plan, as amended, (ii) Non-Statutory Director Stock Option Plan, as amended, and (iii) 1987 Incentive Stock Option Plan, as amended. (d) To the extent that Parent, at Parent's sole option, directs the Company prior to the Effective Time to terminate the Matador Petroleum Corporation 401(k) Profit Sharing Plan and in sufficient time to provide any required advance notices to participants in such plan with respect to such termination, the Company shall terminate such plan immediately prior to the Effective Time in the manner reasonably requested by Parent; provided, however, the Company shall not be required to prepare or make any filings with the Internal Revenue Service in connection with such termination prior to the Effective Time. 31 Section 6.05. Indemnification. (a) After the Effective Time, Parent will cause the Surviving Corporation to indemnify, defend and hold harmless each person who is now, or has been at any time prior to the date hereof, a director or officer of the Company or any of its Subsidiaries (individually, an "Indemnified Party" and, collectively, the "Indemnified Parties") with respect to any liability, loss, damage, judgment, fine, penalty, amount paid in settlement or compromise with the approval of the Parent (which approval shall not be unreasonably withheld or delayed), cost or expense (including reasonable fees and expenses of legal counsel) incurred in connection with any threatened or actual action, suit or proceeding based on, or arising out of, the fact that such person is or was a director or officer of the Company or any of its Subsidiaries ("Indemnified Liabilities"), in each case, to the full extent that the Surviving Corporation is permitted under applicable Texas Law to so indemnify. Any Indemnified Party desiring to claim indemnification under this Section 6.05(a), upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify Parent and the Surviving Corporation (but the failure so to notify shall not relieve the indemnifying party from any liability which it may have under this Section 6.05(a) except to the extent such failure materially prejudices such indemnifying party). After the Surviving Corporation's receipt of such notice with respect to any such claim, action, suit, proceeding or investigation, the Surviving Corporation shall have the right to assume and direct all aspects of the defense thereof, including settlement, and the Indemnified Party shall cooperate in the vigorous defense of any such matter. In no event shall Parent or the Surviving Corporation be liable for any settlement effected without its prior written consent. If any determination that an Indemnified Party's conduct complies with the standards set forth in the TBCA is required to be made, such determination shall be made by independent counsel mutually acceptable to the Surviving Corporation and the Indemnified Party; and provided, further, that nothing herein shall impair any rights or obligations of any Indemnified Party. The Surviving Corporation shall promptly advance all reasonable out-of-pocket expenses of each Indemnified Party in connection with any such action, suit or proceedings described above, as such expenses are incurred, to the fullest extent permitted by the TBCA, subject to the receipt by the Surviving Corporation of an undertaking by or on behalf of such Indemnified Party to repay such amount if it shall ultimately be determined that such Indemnified Party is not entitled to be indemnified by the Surviving Corporation. The rights to indemnification under this Section 6.05(a) shall continue in full force and effect for a period of six years from the Effective Time; provided, however, that all rights to indemnification in respect of any Indemnified Liabilities asserted or made within such period shall continue until the final disposition of such Indemnified Liabilities. (b) For a period of six years after the Effective Time, Parent shall cause to be maintained, to the extent such coverage is then reasonably available, policies of directors' and officers' liability insurance providing coverage with respect to matters occurring prior to the Effective Time that is substantially equal to the coverage provided under the Company's directors' and officers' liability insurance policies existing on the date of the Agreement with respect to claims arising from facts or events which occurred before the Effective Time; provided, however, that in no event shall this covenant require annual expenditures of more than 150% of the last annual premiums paid prior to the date hereof by the Company for such insurance. 32 (c) Parent shall assume by written instrument delivered at the Closing each indemnification agreement between the Company and any of its former and existing officers and directors which was in force and effect immediately prior to the date of this Agreement and is listed on Schedule 3.14 of the Company Disclosure Letter. (d) In the event Parent or the Surviving Corporation or any of their successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation shall assume the obligations set forth in this Section 6.05. (e) The provisions of this Section 6.05 are (i) intended to be for the benefit of, and to be enforceable by, each Indemnified Party, his or her heirs and his or her representatives and (ii) in addition to, and not in substitution for, any other rights to indemnification or contribution that any such person may have by contract or otherwise. Parent agrees to pay all expenses (including fees and expenses of counsel) that may be incurred by any Indemnified Party in successfully enforcing the indemnity or other obligations under this Section 6.05. Section 6.06. Fees and Expenses. (a) Except as provided below, all fees and expenses incurred in connection with the Merger and this Agreement shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated. (b) In the event that this Agreement is terminated (i) by the Company pursuant to Section 8.01(d) (superior proposal), (ii) by Parent pursuant to Section 8.01(c)(i) (change in recommendation) or (iii) by Parent or the Company pursuant to Section 8.01(b)(iii) (failure to obtain Company Shareholder Approval) after a Change in Recommendation, then the Company shall promptly, but in no event later than the date of such termination (or one business day after such termination if terminated by Parent), pay to Parent a fee equal to $20.0 million (the "Termination Fee"), by wire transfer of same day funds to an account designated by Parent, which shall be deemed to be sole and exclusive remedy and liquidated damages payable to Parent for such termination because Parent's actual damages would be difficult to ascertain. (c) In the event there has not been a Change in Recommendation prior to the Company Shareholder Meeting and this Agreement is terminated by Parent or the Company pursuant to Section 8.01(b)(iii) (failure to obtain Company Shareholder Approval) or Section 8.01(b)(ii) (expiration date of this Agreement) and (x) within one hundred eighty (180) days after the date of such termination, the Company or any of its Subsidiaries enters into an agreement for or consummates a transaction that constitutes a Company Takeover Proposal, or (y) after the date of this Agreement and prior to such termination, there shall have been made a Company Takeover Proposal or any proposal or expression of interest by a third party regarding a Company Takeover Proposal shall have been disclosed publicly or generally to the Company's shareholders and within twelve (12) months of the date of such termination the Company or any of its Subsidiaries enters into any agreement for or consummates a transaction that constitutes a Company Takeover Proposal with the person (or one of its affiliates) who made (or expressed interest in) a Company Takeover Proposal as described in this clause (y), then in either case the 33 Company will prior to the earlier of consummation of a transaction that constitutes a Company Takeover Proposal or execution of a definitive agreement with respect thereto, pay to Parent an amount equal to the Termination Fee less any amount previously paid to Parent pursuant to Section 6.06(d), by wire transfer of same day funds to an account designated by Parent, which shall be deemed to be the sole and exclusive remedy and liquidated damages payable to Parent for such termination because Parent's actual damages would be difficult to ascertain. (d) In the event there has not been a Change in Recommendation prior to the Company Shareholder Meeting and this Agreement is terminated by Parent or the Company pursuant to Section 8.01(b)(iii) (failure to obtain Company Shareholder Approval) and after the date hereof and prior to such termination there shall not have been made a Company Takeover Proposal and no proposal or expression of interest by a third party regarding a Company Takeover Proposal shall have been disclosed publicly or generally to the Company's shareholders, then the Company shall promptly, but in no event later than the date of such termination (or one business day after such termination if terminated by Parent), pay to Parent $4.0 million as payment in full of Parent's estimated expenses, by wire transfer of same day funds to an account designated by Parent. Section 6.07. Public Announcements. Parent and Sub, on the one hand, and the Company, on the other hand, shall consult with each other before issuing, and provide each other the opportunity to review and comment upon, any press release or otherwise making any such public statements with respect to the Merger and shall not issue any such press release or make any such public statement prior to such consultation, except after reasonable attempts to provide notice have been undertaken and if such release or statement is required by applicable Law.

Each party shall cooperate with the other in preparing, executing and filing any Tax Returns with respect to such Transfer Taxes, including supplying in a timely manner a complete list of all real property interests held by the Company or any of its Subsidiaries and any information with respect to such property that is reasonably necessary to complete such Tax Returns.
