A majority of the Committee shall constitute a quorum, and the acts of the members of the Committee who are present at any meeting thereof at which a quorum is present, or acts unanimously approved by the members of the Committee in writing, shall be the acts of the Committee. Subject to the terms of the Plan and applicable law, and in addition to other express powers and authorizations conferred on the Committee by the Plan, the Committee shall have full power and authority to: (i) designate Participants; (ii) determine the type or types of Awards to be granted to an eligible Employee; (iii) determine the number of Shares to be covered by, or with respect to which payments, rights, or other matters are to be calculated in connection with, Awards; (iv) determine the terms and conditions of any Award; (v) determine whether, to what extent, and under what circumstances Awards may be settled or exercised in cash, Shares, other securities, other Awards or other property, or cancelled, forfeited, or suspended and the method or methods by which Awards may be settled, exercised, cancelled, forfeited, or suspended; (vi) determine whether, to what extent, and under what circumstances cash, Shares, other securities, other Awards, other property, and other amounts payable with respect to an Award shall be deferred either automatically or at the election of the holder thereof or of the Committee; (vii) interpret and administer the Plan and any instrument or agreement relating to, or Award made under, the Plan; (viii) establish, amend, suspend, or waive such rules and regulations and appoint such agents as it shall deem appropriate for the proper administration of the Plan; and (ix) make any other determination and take any other action that the Committee deems necessary or desirable for the administration of the Plan.

The provisions of this Section 3 with respect to decisions made by, and authority of, the Committee shall be subject to the controlling provisions of Section 6(h). SECTION 4. SHARES AVAILABLE FOR AWARDS (a) Shares Available Subject to Section 4(d) and to adjustment as provided in Section 4(c), the number of Shares with respect to which Awards may be granted under the Plan shall be 4,000,000. If, after the effective date of the Plan, any Shares covered by an Award granted under the Plan, or to which such an Award relates, are forfeited, or if an Award otherwise terminates or is cancelled without the delivery of Shares or of other consideration, then the Shares covered by such Award, or to which such Award relates, or the number of Shares otherwise counted against the aggregate number of Shares with respect to which Awards may be granted, to the extent of any such forfeiture, termination or cancellation, shall again be, or shall become, to the extent permissible under Rule 16b-3, Shares with respect to which Awards may be granted. In the event that any Option or other Award granted hereunder is exercised through the delivery of Shares, the number of Shares available for Awards (other than an Incentive Stock Option) under the Plan shall be increased by the number of Shares surrendered, to the extent permissible under Rule 16b-3. Notwithstanding the foregoing, no more than 1,200,000 Shares available for Awards shall be issued as Restricted Stock. (b) Sources of Shares Deliverable Under Awards Any Shares delivered pursuant to an Award may consist, in whole or in part, of authorized and unissued Shares or of treasury Shares. 3 4 (c) Adjustments In the event that the Committee determines that any dividend or other distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, issuance of warrants or other rights to purchase Shares or other securities of the Company, or other similar corporate transaction or event affects the Shares such that an adjustment is determined by the Committee to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, then the Committee shall, in such manner as it may deem equitable, adjust any or all of (i) the number and type of Shares (or other securities or property) with respect to which Awards may be granted, (ii) the number and type of Shares (or other securities or property) subject to outstanding Awards, and (iii) the grant or exercise price with respect to any Award or, if deemed appropriate, make provision for a cash payment to the holder of an outstanding Award; provided, in each case, that with respect to Awards of Incentive Stock Options and Awards intended to qualify as performance based compensation under Section 162(m)(4)(C) of the Code, no such adjustment shall be authorized to the extent that such authority would cause the Plan to violate Section 422(b)(1) of the Code or would cause such Award to fail to so qualify under Section 162(m) of the Code, as the case may be, or any successor provisions thereto; and provided, further, that the number of Shares subject to any Award denominated in Shares shall always be a whole number. (d) Substitute Awards Any Shares underlying Substitute Awards shall not, except in the case of Shares with respect to which Substitute Awards are granted with respect to Incentive Stock Options or, if not permissible under Rule 16b-3, to Employees who are officers or directors of the Company for purposes of Section 16 of the Exchange Act or any successor section thereto, be counted against the Shares available for Awards other than Incentive Stock Options under the Plan. SECTION 5. ELIGIBILITY Other than Awards granted to non-employee Directors pursuant to Section 6(h) of the Plan, any Employee who is not a member of the Committee, including any officer or employee-director of the Company or any Affiliate, shall be eligible to be designated a Participant. All Employees shall be eligible for Awards under the Plan. However, no Employee under this Plan may receive in any calendar year Stock Options and/or Rights that, in the aggregate, are with respect to more than 500,000 Shares (tandem Awards shall be deemed to be one Award for this purpose). SECTION 6. AWARDS (a) Options Subject to the provisions of the Plan, the Committee shall have authority to determine the Employees to whom Options shall be granted, the number of Shares to be covered by each Option, the purchase price therefor and the conditions and limitations applicable to the exercise of the option including the following terms and conditions and such additional terms and conditions, as the Committee shall determine are not inconsistent with the provisions of the Plan. (i) Exercise Price. The purchase price per Share purchasable under an Option shall be determined by the Committee at the time each Option is granted; provided, however, that the purchase price per Share shall not be less than 100% of the Fair Market Value on the date of grant, except in the case of Options that are Substitute Awards. (ii) Time and Method of Exercise. The Committee shall determine the time or times at which an Option may be exercised in whole or in part, and the method or methods by which, and the form or forms (which may include, without limitation, cash, Shares, outstanding Awards, Shares that would otherwise be acquired upon exercise of the Option, other securities or other property, or any combination thereof, 4 5 having a Fair Market Value on the exercise date equal to the relevant exercise price) in which payment of the exercise price with respect thereto may be made or deemed to have been made. Pursuant to Section 7(b) of the Plan, the Committee may, at its discretion, accelerate the time at which Options may be exercised and otherwise modify the time or methods of exercise of the Options. (iii) Incentive Stock Options. The terms of any Incentive Stock Option granted under the Plan shall comply in all respects with the provisions of Section 422 of the Code, or any successor provision, and any regulations promulgated thereunder. Incentive Stock Options may be granted only to Employees of the Company and its "subsidiaries" within the meaning of Section 424(f) of the Code. (b) Stock Appreciation Rights Subject to the provisions of the Plan, the Committee shall have authority to determine the Employees to whom Stock Appreciation Rights shall be granted, the number of Shares to be covered by each Stock Appreciation Right Award, the grant price thereof and the conditions and limitations applicable to the exercise thereof. A Stock Appreciation Right may be granted in tandem with another Award, in addition to another Award, or freestanding and unrelated to another Award. A Stock Appreciation Right granted in tandem with or in addition to another Award may be granted either at the same time as such other Award or at a later time. (i) Grant Price. The grant price of a Stock Appreciation Right shall be determined by the Committee; provided, however, that the grant price shall not be less than 100% of the Fair Market Value on the date of grant or on the date of original grant of any related Award. (ii) Other Terms and Conditions. Subject to the terms of the Plan and any applicable Award Agreement, the Committee shall determine, at or after the grant of a Stock Appreciation Right, the term, methods of exercise, methods of settlement, and any other terms and conditions of any Stock Appreciation Right. Any such determination by the Committee may be changed by the Committee from time to time and may govern the exercise of Stock Appreciation Rights granted or exercised prior to such determination as well as Stock Appreciation Rights granted or exercised thereafter. The Committee may impose such conditions or restrictions on the exercise of any Stock Appreciation Right as it shall deem appropriate. (c) Restricted Stock Subject to the provisions of the Plan, the Committee shall have authority to determine the Employees to whom Restricted Stock shall be granted, the number of Shares of Restricted Stock to be granted to each such Participant, the duration of the Restricted Period during which, and the conditions under which, the Restricted Stock may be forfeited to the Company, and the other terms and conditions of such Awards. (i) Dividends. Unless otherwise determined by the Committee, Restricted Stock Awards shall provide for the payment of dividends during the Restricted Period. Any Restricted Stock Award may require that any or all dividends or other distributions paid on the Restricted Stock during the Restricted Period be automatically sequestered and held in a bookkeeping cash account (with or without interest) or reinvested on an immediate or deferred basis in additional shares of Common Stock, which credit or shares may be subject to the same restrictions as the underlying Award or such other restrictions as the Committee may determine. Dividends paid on Restricted Stock may be paid directly to the Participant, may be subject to risk of forfeiture and/or transfer restrictions during any period established by the Committee, all as determined by the Committee in its discretion. (ii) Registration. Any Restricted Stock may be evidenced in such manner as the Committee shall deem appropriate, including, without limitation, book-entry registration or issuance of a stock certificate or certificates. In the event any stock certificate is issued in respect of Restricted Stock granted under the Plan, such certificate shall be registered in the name of the Participant and shall bear an appropriate legend referring to the terms, conditions, and restrictions applicable to such Restricted Stock. 5 6 (iii) Forfeiture and Restrictions Lapse. Except as otherwise determined by the Committee or the terms of the Award that granted the Restricted Stock, upon termination of a Participant's employment (as determined under criteria established by the Committee, including, without limitation, in the Committee's discretion, goals described under Section 6(d)(i)) for any reason during the applicable Restricted Period, all Restricted Stock shall be forfeited by the Participant and re-acquired by the Company. The Committee may, when it finds that a waiver would be in the best interests of the Company and not cause such Award, if it is intended to qualify as performance based compensation under Section 162(m) of the Code, to fail to so qualify under Section 162(m) of the Code, waive in whole or in part any or all remaining restrictions with respect to such Participant's Restricted Stock. Unrestricted Shares, evidenced in such manner as the Committee shall deem appropriate, shall be issued to the holder of Restricted Stock promptly after the applicable restrictions have lapsed or otherwise been satisfied. (iv) Transfer Restrictions. During the Restricted Period, Restricted Stock will be subject to the limitations on transfer as provided in Section 6(i)(iii). (d) Performance Awards The Committee shall have authority to determine the Employees who shall receive a Performance Award, which shall (A) consist of a right, denominated or payable in cash, Shares, Deferred Shares, other securities or other property (including, without limitation, Restricted Stock, or any combination thereof), and (B) confer on the holder thereof rights valued as determined by the Committee and payable to, or exercisable by, such holder, in whole or in part, upon the achievement of such performance goals during such performance periods as the Committee shall establish. (i) Terms and Conditions. Subject to the terms of the Plan and any applicable Award Agreement, the Committee shall determine the performance goals to be achieved during any performance period, the length of any performance period, the amount of any Performance Award and the amount of any payment or transfer to be made pursuant to any Performance Award. Without limiting the generality of the foregoing, it is intended that the Committee may establish performance goals applicable to Performance Awards granted to Participants who, in the judgment of the Committee, may be Covered Employees in such a manner as shall permit payments with respect thereto to qualify as "performance-based compensation" as described in Section 162(m)(4)(C) of the Code. It is specifically provided that the material terms of such performance goals for Participants who, in the judgment of the Committee, may be Covered Employees, shall, until changed by the Committee with the approval of the stockholders, if such stockholder approval is required by the Code, be as follows: (x) the business criteria on which the performance goals shall be based shall be the attainment of such target levels of either net income, cash flows, reserve additions or revisions, total capitalization, total shareholder return, assets, exploration successes, production volumes, finding and development costs, costs reductions and savings, reportable incidents in safety or environmental matters, return on sales, profit margin, earnings per share or personal objectives tied to operational studies, implementing policies and plans, negotiating transactions and sales, developing long-term business goals, managerial responsibilities and assessments as may be specified by the Committee; and (y) the maximum amount of compensation that may be paid to any one Participant with respect to any one year shall be $1.5 million under an annual performance bonus Award and $1.5 million under a long-term Award with a performance period longer than one fiscal year. (ii) Payment of Performance Awards. Performance Awards may be paid in a lump sum or in installments following the close of the performance period or, in accordance with procedures established by the Committee, on a deferred basis. (e) Stock Compensation and Bonus Shares (i) Stock Compensation. The Committee shall have the authority, in its discretion, to pay in Shares all, or such portion as it shall determine, of amounts payable (x) under any Award of the Plan, other than Performance Awards payable in cash as a short term annual incentive or Cash Awards granted in tandem with Restricted Stock or (y) if requested by an Employee, under any compensation program of the Company. The 6 7 number and type of Shares to be distributed in lieu of the cash compensation to which an Employee would otherwise be entitled, as well as the terms and conditions of any such bonus awards, shall be determined by the Committee. (ii) Bonus Shares. The Committee may also grant Bonus Shares to eligible Employees. Each Bonus Share shall constitute a transfer of Common Shares to the Participant, without other payment therefor, as additional compensation for the Participant's services to the Company. (f) Deferred Shares The Committee may also grant Awards of Deferred Shares to eligible Employees upon such terms and conditions as the Committee may determine. (i) Terms and Conditions. Each Deferred Share award shall constitute an agreement by the Company to issue or transfer a specified number of Shares to the Participant in the future, subject to the fulfillment during the Restricted Period of such conditions, including performance objectives or, as described in Section 6(d)(i), performance goals, if any, as the Committee may specify at the date of grant. During the Restricted Period, the Participant shall not have any right to transfer any rights under the subject Award, shall not have any rights of ownership in the Deferred Shares and shall not have any right to vote such shares. (ii) Dividends. Any Deferred Share award may provide that any or all dividends or other distributions paid on Shares during the Restricted Period be credited in a cash bookkeeping account (without interest) or that equivalent additional Deferred Shares be awarded, which account or shares may be subject to the same restrictions as the underlying Award or such other restrictions as the Committee may determine. (g) Other Stock-Based and Cash Awards (i) Other Stock Based Awards. The Committee is hereby authorized to grant to eligible Employees an "Other Stock-Based Award," which shall consist of a right (i) which is not an Award or right described in Section 6(a), (b), (c), (d), (e) or (f) above and (ii) which is denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, Shares (including, without limitation, securities convertible into Shares) as are deemed by the Committee to be consistent with the purposes of the Plan; provided, that any such rights must comply, to the extent deemed desirable by the Committee, with Rule 16b-3 and applicable law. Subject to the terms of the Plan and any applicable Award Agreement, the Committee shall determine the terms and conditions of any such Other Stock-Based Award. (ii) Cash Awards. Subject to the provisions of the Plan, the Committee shall have authority to determine the Employees to whom Cash Awards shall be granted, the amount, and the terms or conditions, if any, as additional compensation for the Employee's services to the Company or its Affiliates. A Cash Award may be granted (simultaneously or subsequently) in tandem with another Award and may entitle a Participant to receive a specified amount of cash from the Company upon such other Award becoming taxable to the Participant, which cash amount may be based on a formula relating to the anticipated taxable income associated with such other Award and the payment of the Cash Award or other terms determined by the Committee. (h) Awards to Non-employee Directors (i) Initial Granting of Options. Subject to stockholder approval of the Plan pursuant to Section 10, and to the limitation of the number of shares of Stock set forth in Section 4(a), each non-employee Director who serves in such capacity on the date of the approval of the Plan by the Board (the "Current non-employee Directors") shall receive, as of such date and without the exercise of the discretion of any person or persons, a Non-Qualified Stock Option exercisable for 5,000 shares of Stock. Subject to stockholder approval of the Plan pursuant to Section 10, and to the limitation of the number of shares of Stock set forth in Section 4(a), each non-employee Director who is elected or appointed to the Board for the first time after the effective date of the 7 8 Plan (excluding the Current non-employee Directors) shall receive, as of the date of his or her election or appointment and without the exercise of the discretion of any person or persons, a Non-Qualified Stock Option exercisable for 5,000 shares of Stock (subject to adjustment in the same manner as provided in Section 7 hereof with respect to shares of Stock subject to Options then outstanding). Any nominee non-employee Director may make an irrevocable election in advance of election not to receive an option pursuant to this Section 6(h)(i). (ii) Annual Granting of Options. Subject to stockholder approval of the Plan pursuant to Section 10, and to the limitation of the number of shares of Stock set forth in Section 4(a), as of the date of the annual meeting of the stockholders of the Company in each year that the Plan is in effect as provided in Section 11 hereof (commencing with the 1995 annual meeting of stockholders), each non-employee Director who is in office immediately after such meeting and who is not then entitled to receive an Option pursuant to the preceding provisions of this Section 6(h) shall receive, without the exercise of the discretion of any person or persons, a Non-Qualified Stock Option exercisable for 3,000 shares of Stock (subject to adjustment in the same manner as provided in Section 7 hereof with respect to shares of Stock subject to Options then outstanding). Any non-employee Director may make an irrevocable election in advance not to receive an option pursuant to this Section 6(h)(ii). (iii) Other Terms and Conditions. The following provisions are applicable to Options granted pursuant to Sections 6(h)(i) and (ii): A. Options shall be exercisable on the day following the date of grant. B. The purchase price of a Share covered under an Option granted under this Section 6(h) shall be the Fair Market Value of a Share on the date of grant. C. The Option may be exercised in full at one time or in part from time to time by giving written notice, signed by the optionee exercising the Option, to the Company, stating the number of Shares with respect to which the Option is being exercised, accompanied by payment in full for such Shares, which payment may be in whole or in part in Shares of the Company already owned by said optionee, valued at Fair Market Value; provided, however, that (i) no Option shall be exercisable after ten (10) years from the date on which it was granted, and (ii) there shall be no such exercise at any one time for fewer than one hundred (100) Shares or for all of the remaining Shares then purchasable by the optionee exercising the Option, if fewer than one hundred (100) Shares. D. Each Option shall expire ten (10) years from the date of grant thereof, but shall be subject to earlier termination as follows. Options, to the extent exercisable as of the date a non-employee Director optionee ceases to serve as a director of the Company, must be exercised within six months of such date unless such event results from death, Disability or Retirement, in which case Options may be exercised by the optionee, the optionee's legal representative, heir or devisee, as the case may be, within two (2) years from the date of death or Disability and within three (3) years from the date of Retirement; provided, however, that no such event shall extend the normal expiration date of such Options. E. Upon exercise of the Option, subject to paragraph F below, delivery of a certificate for fully paid and nonassessable Shares shall be made either at the corporate office of the Company in Houston, Texas to the optionee exercising the Option at such time during ordinary business hours after fifteen (15) days but not more than thirty (30) days from the date of receipt of the notice by the Company as shall be designated in such notice, or at such time, place and manner as may be agreed upon by the Company and the optionee exercising the Option. F. Until the earlier to occur of the following events (i) the non-employee Director no longer serves as a Director of the Company for any reason, (ii) a Change in Control, (iii) the approval by the Company's stockholders of a merger or consolidation or (iv) a tender offer for the Common Stock of the Company ("Termination of Restriction"), the Shares received by the non-employee Director upon the exercise of an Option granted pursuant to Section 6(h)(i) and (ii) shall not be subject to disposition by the non-employee Director, by sale, transfer, alienation, anticipation, pledge, encumbrance, assignment or any other means whether such disposition be voluntary or involuntary or by operation of law by judgment, 8 9 levy, attachment, garnishment or any other legal or equitable proceeds (including bankruptcy), and any attempted disposition thereof, shall be null and void and of no effect; provided, however, that nothing in this Section 6(h)(iii)F shall prevent transfer by will, the applicable laws of descent and distribution or pursuant to a qualified domestic relations order. The certificates evidencing the Shares may bear a legend restricting or incorporating the restrictions, and the Company may cause the certificates to be delivered upon issuance to the Secretary of the Company or such other depositary as may be designated by the Company as a depositary for safe-keeping until Termination of Restriction. Upon Termination of Restriction, the Company will cause a new certificate or certificates to be issued without legend in the name of such former director. (iv) Notwithstanding anything in the Plan to the contrary, a non-employee Director shall be ineligible to receive a grant provided for in Section 6(h) if as of the date of such grant the Director (i) is an employee of the Company or any Affiliate or (ii) has been an employee of the Company or any Affiliate for any part of the calendar year preceding the calendar year in which such a grant is to be made. (v) In the event that the number of Shares available for grants under the Plan is insufficient to make all grants provided for in this Section 6(h) hereby made on the applicable date, then all non-employee Directors who are entitled to a grant on such date shall share ratably in the number of Shares then available for grant under the Plan, and shall have no right to receive a grant with respect to the deficiencies in the number of available Shares and the grants under this Section 6(h) shall terminate. (vi) Except as expressly provided in this Section 6(h) grants made pursuant to this Section 6(h) shall be subject to the terms and conditions of the Plan; however, if there is a conflict between the terms and conditions of the Plan and this Section 6(h) then the terms and conditions of this Section 6(h) shall control. The Committee may not exercise any discretion with respect to this Section 6(h) which would be inconsistent with the intent expressed in Section 6(h)(vii). (vii) It is intended that the Plan meet the requirements of Rule 16b-3 and that any non-employee Director who is eligible to receive a grant or to whom a grant is made pursuant to this Section 6 will not for such reason cease to be a "disinterested person" within the meaning of Rule 16b-3 with respect to the Plan and other stock related plans of the Company. (viii) All Options under this Section 6(h) shall be evidenced by Award Agreements. (i) General (i) Awards May Be Granted Separately or Together. Awards may, in the discretion of the Committee, be granted either alone or in addition to, in tandem with, or in substitution for any other Award granted under the Plan or any award granted under any other plan of the Company or any Affiliate. Awards granted in addition to or in tandem with other Awards or awards granted under any other plan of the Company or any Affiliate may be granted either at the same time as or at a different time from the grant of such other Awards or awards. (ii) Forms of Payment by Company Under Awards. Subject to the terms of the Plan and of any applicable Award Agreement, payments or transfers to be made by the Company or an Affiliate upon the grant, exercise or payment of an Award may be made in such form or forms as the Committee shall determine, including, without limitation, cash, Shares, other securities, other Awards or other property, or any combination thereof, and may be made in a single payment or transfer, in installments, or on a deferred basis, in each case in accordance with rules and procedures established by the Committee. Such rules and procedures may include, without limitation, provisions for the payment or crediting of reasonable interest on installment or deferred payments. (iii) Limits on Transfer of Awards (A) Each Award, and each right under any Award, shall be exercisable only by the Participant during the Participant's lifetime, or, if permissible under applicable law, by the Participant's guardian or 9 10 legal representative or by a transferee receiving such Award pursuant to a qualified domestic relations order (a "QDRO") as determined by the Committee. (B) No Award and no right under any such Award may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant otherwise than by will or by the laws of descent and distribution (or, in the case of Restricted Stock, to the Company) or pursuant to a QDRO and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or any Affiliate. (C) To the extent approved by the Committee and in compliance with Rule 16b-3 and the Securities Act of 1933, as amended, a Non-Qualified Stock Option may be transferred to immediate family members. (iv) Term of Awards. The term of each Award (other than pursuant to Section 6(h)) shall be for such period as may be determined by the Committee; provided, that in no event shall the term of any Incentive Stock Option Award exceed a period of ten years from the date of its grant. (v) Share Certificates. All certificates for Shares or other securities of the Company or any Affiliate delivered under the Plan pursuant to any Award or the exercise thereof shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan or the rules, regulations, and other requirements of the SEC, any stock exchange upon which such Shares or other securities are then listed, and any applicable Federal or state laws, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. (vi) Consideration for Grants. Awards may be granted for no cash consideration or for such consideration as the Committee determines including, without limitation, such minimal cash consideration as may be required by applicable law. (vii) Delivery of Shares or other Securities and Payment by Participant of Consideration. No Shares or other securities shall be delivered pursuant to any Award until payment in full of any amount required to be paid pursuant to the Plan or the applicable Award Agreement is received by the Company. Such payment may be made by such method or methods and in such form or forms as the Committee shall determine, including, without limitation, cash, Shares, other securities, other Awards or other property, withholding of Shares, cashless exercise with simultaneous sale, or any combination thereof; provided, that the combined value, as determined by the Committee, of all cash and cash equivalents and the Fair Market Value of any such Shares or other property so tendered to the Company, as of the date of such tender, is at least equal to the full amount required to be paid pursuant to the Plan or the applicable Award Agreement to the Company. SECTION 7. AMENDMENT AND TERMINATION Except to the extent prohibited by applicable law and unless otherwise expressly provided in an Award Agreement or in the Plan: (a) Amendments to the Plan The Board may amend, alter, suspend, discontinue, or terminate the Plan without the consent of any shareholder, Participant, other holder or beneficiary of an Award, or other Person; provided, however, that the provisions of Section 6(h) may not be amended more than once every six months other than to comport with changes in the Code, the Employee Retirement Income Security Act of 1974, as amended, or the rules thereunder and; provided, further, that notwithstanding any other provision of the Plan or any Award Agreement, without the approval of the stockholders of the Company no such amendment, alteration, suspension, discontinuation, or termination shall be made that would: (i) increase the total number of Shares available for Awards under the Plan, except as provided in Section 4(c) of the Plan; 10 11 (ii) permit Incentive Stock Options to be granted with per Share grant, exercise or purchase prices of less than the Fair Market Value of a Share on the date of grant thereof; or (iii) result in this Plan no longer satisfying the requirements of Rule 16b-3. (b) Amendments to Awards The Committee may waive any conditions or rights under, amend any terms of, or alter any Award theretofore granted (other than Awards granted pursuant to Section 6(h)), provided no change in any Award, other than pursuant to Section 7(c), shall reduce the benefit to Participant without the consent of such Participant. Notwithstanding the foregoing, with respect to any Award intended to qualify as performance-based compensation under Section 162(m) of the Code, no adjustment shall be authorized to the extent such adjustment would cause the Award to fail to so qualify. (c) Adjustment of Awards Upon the Occurrence of Certain Unusual or Nonrecurring Events The Committee is hereby authorized to make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events (including, without limitation, the events described in Section 4(c) of the Plan) affecting the Company, any Affiliate, or the financial statements of the Company or any Affiliate, or of changes in applicable laws, regulations, or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan. Notwithstanding the foregoing, with respect to any Award intended to qualify as performance-based compensation under Section 162(m) of the Code, no adjustment shall be authorized to the extent such adjustment would cause the Award to fail to so qualify. SECTION 8. CHANGE IN CONTROL (a) In addition to the Committee's authority set forth in Section 7(c) of the Plan, in order to maintain the Participants' rights in the event of any Change in Control, as hereinafter defined, the Committee, as constituted before such Change in Control, is hereby authorized and directed to provide for the acceleration of any time periods relating to the exercise or realization of all Awards so that such Award may be exercised or realized in full, and has sole discretion, as to any Award, either at the time such Award is made hereunder or any time thereafter, to take any one or more of the following actions: (i) provide for the purchase of any such Award, either automatically or upon the Participant's request, for an amount of cash equal to the amount that could have been attained upon the exercise of such Award or realization of the Participant's rights had such Award been currently exercisable or payable; (ii) make such adjustment to any such Award then outstanding as the Committee deems appropriate to reflect such Change in Control; or (iii) if equitable and in the best interests of the Company and its stockholders, cause (x) any such Award then outstanding to be assumed, or new rights substituted therefor, by the acquiring or surviving corporation after such Change in Control or (y) the exercise period for any such Award then outstanding to terminate on a fixed date following such Change in Control provided the Participant receives written notice of such event and the fixed date at least twenty days prior to the effective date of such Change in Control. The Committee may, in its discretion, include such further provisions and limitations in any Award Agreement as it may deem equitable and in the best interests of the Company and its stockholders. (b) A "Change in Control" shall be deemed to occur (i) if any person or persons or entity or entities (other than Petroleum Associates, L.P., KKR Partners II, L.P. and any entity controlling, controlled by or under common control with any such entities, separately or in the aggregate ("KKR")) acquires 75% or more of the assets of the Company or a successor of the Company or such successor's parent corporation (based upon the then current fair market value thereof) or 50% or more of the Company's then outstanding voting stock or a successor's or such successor's parent corporation's then outstanding voting securities, and, if there shall be more than one class of voting securities thereof, then of the combined voting power held by all classes of voting securities of the Company, a successor corporation or its parent corporation (whether such acquisition of stock or assets occurs pursuant to a single transaction or several related transactions or series of 11 12 transactions), (ii) upon the approval by the Company's stockholders of a plan of liquidation or dissolution of the Company or a successor of the Company or such successor's parent corporation, or (iii) upon the approval by the Company's stockholders of a merger or consolidation and such transaction was determined to be a Change in Control, which transaction and determination was approved by a majority of the Company's Board of Directors in actions taken prior to, and with respect to such transaction. SECTION 9. GENERAL PROVISIONS (a) No Rights to Awards No Employee, Participant or other Person shall have any claim to be granted any Award, and there is no obligation for uniformity of treatment of Employees, Participants, or holders or beneficiaries of Awards. The terms and conditions of Awards need not be the same with respect to each recipient. (b) Delegation Subject to the terms of the Plan and applicable law, the Committee may delegate to one or more officers or managers of the Company or any Affiliate, or to a committee of such officers or managers, the authority, subject to such terms and limitations as the Committee shall determine, to grant Awards to, or to cancel, modify or waive rights with respect to, or to alter, discontinue, suspend, or terminate Awards held by, Employees who are not officers or directors of the Company for purposes of Section 16 of the Exchange Act, or any successor Section thereto, or who are otherwise not subject to such Section. (c) Withholding The Company or any Affiliate is hereby authorized to withhold from any Award, from any payment due or transfer made under any Award or under the Plan or from any compensation or other amount owing to a Participant the amount (in cash, Shares, other securities, Shares that would otherwise be issued pursuant to such Award (including automatic withholding), other Awards or other property) of any applicable taxes payable in respect of an Award, its exercise, the lapse of restrictions thereon, or any payment or transfer under an Award or under the Plan and to take such other action as may be necessary in the opinion of the Company to satisfy all obligations for the payment of such taxes. (d) No Limit on Other Compensation Arrangements Nothing contained in the Plan shall prevent the Company or any Affiliate from adopting or continuing in effect other compensation arrangements (subject to shareholder approval of such other arrangement, if such approval is required), and such arrangements may be either generally applicable or applicable only in specific cases. (e) No Right to Employment The grant of an Award shall not be construed as giving a Participant the right to be retained in the employ of the Company or any Affiliate. Further, the Company or an Affiliate may at any time dismiss a Participant from employment, free from any liability or any claim under the Plan, unless otherwise expressly provided in the Plan or in any Award Agreement. (f) Governing Law The validity, construction, and effect of the Plan and any rules and regulations relating to the Plan shall be determined in accordance with the laws of the State of Delaware and applicable Federal law. (g) Severability If any provision of the Plan or any Award is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any Person or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to 12 13 conform to the applicable laws, or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be stricken as to such jurisdiction, Person or Award and the remainder of the Plan and any such Award shall remain in full force and effect. (h) Other Laws The Committee may refuse to issue or transfer any Shares or other consideration under an Award if, acting in its sole discretion, it determines that the issuance of transfer or such Shares or such other consideration might violate any applicable law or regulation or entitle the Company to recover the same under Section 16(b) of the Exchange Act, and any payment tendered to the Company by a Participant, other holder or beneficiary in connection with the exercise of such Award shall be promptly refunded to the relevant Participant, holder or beneficiary. It is intended that the Plan and any grant of an Award made to a person subject to Section 16 of the Exchange Act meet all of the requirements of Rule 16b-3. If any provision of the Plan or any such Award would disqualify the Plan or such Award under, or would otherwise not comply with, Rule 16b-3, such provision or Award shall be construed or deemed amended to conform to Rule 16b-3. (i) No Trust or Fund Created Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any Affiliate and a Participant or any other Person. To the extent that any Person acquires a right to receive payments from the Company or any Affiliate pursuant to an Award, such right shall be no greater than the right of any unsecured general creditor of the Company or any Affiliate. (j) No Fractional Shares No fractional Shares shall be issued or delivered pursuant to the Plan or any Award, and the Committee shall determine whether cash, other securities, or other property shall be paid or transferred in lieu of any fractional Shares or whether such fractional Shares or any rights thereto shall be cancelled, terminated, or otherwise eliminated. (k) Headings Headings are given to the Sections and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision thereof. SECTION 10. EFFECTIVE DATE OF THE PLAN The Plan shall be effective as of November 28, 1994, provided the Plan is subsequently approved by the stockholders of the Company within 12 months thereafter. SECTION 11. TERM OF THE PLAN No Award shall be granted under the Plan after November 27, 2004. However, unless otherwise expressly provided in the Plan or in an applicable Award Agreement, any Award theretofore granted may, and the authority of the Board or the Committee to amend, alter, adjust, suspend, discontinue, or terminate any such Award or to waive any conditions or rights under any such Award shall, extend beyond such date. 13
