Any grant made pursuant to such a delegation shall be subject to all of the provisions of the Plan concerning this type of Award.

(d) Modification of Awards.

At any time after grant of an Award, the Committee may, in its sole and absolute discretion and subject to whatever terms and conditions it selects:

(1) accelerate the period during which the Award vests or becomes exercisable or payable; and

(2) accelerate the time when applicable restrictions or risk of forfeiture or repurchase lapses; and

(3) extend the period during which the Award may be exercised or paid; and

(4) extend the term of any Award (other than the maximum 10 year term);

-4-

provided, that such action may be taken only in compliance with the requirements of Section 162(m) of the Code with respect to an Award that is intended to be performance-based compensation under Section 162(m) of the Code.

SECTION 4. Shares Available for Awards.

(a) Shares Available.

Subject to adjustment as provided below, the number of Shares that may be issued with respect to Awards granted under the Plan shall be 25,500,000. If an Award is forfeited or otherwise lapses, expires, terminates or is canceled without the actual delivery of Shares or is settled in cash, then the Shares covered by such Award, to the extent of such forfeiture, expiration, lapse, termination or cancellation, shall again be Shares that may be issued with respect to Awards granted under the Plan. Shares tendered or withheld by the Company to satisfy tax withholding, exercise price or other payment obligations shall be available for issuance under future Awards, subject to the overall limitation provided in the first sentence above. Notwithstanding the foregoing, no more than 5% of the Shares that may be issued under the Plan may be issued pursuant to Stock Payments.

(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.

(c) Adjustments.

In the event of a stock dividend or stock split with respect to Shares, the number of Shares with respect to which Awards may be granted, the number of Shares subject to outstanding Awards, the grant or exercise price with respect to outstanding Awards and the individual annual grant limits with respect to Awards (other than dollar denominated Awards) automatically shall be proportionately adjusted, without action by the Committee; provided, however, such automatic adjustment shall be evidenced by written addendums to the Plan and Award Agreements prepared by the Company and, with respect to Options, shall be in accordance with the Treasury Regulations concerning Incentive Stock Options. Further, in the event that the Committee determines that any distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, reorganization, merger, spin-off, combination, repurchase, or exchange of 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 that the number of Shares subject to any Award denominated in Shares shall always be a whole number.

-5-

(d) Individual Participant Limits.

Subject to adjustment pursuant to the above paragraph (c), “Adjustments,” the maximum aggregate number of Shares that may be subject to Share-denominated Awards granted under the Plan to any individual during any calendar year shall not exceed 500,000; provided, however, that commencing January 1, 2005, to the extent the 500,000 Share limit is not awarded to any Participant with respect to any calendar year, the amount not so awarded but permitted for such Participant shall be available for award to such Participant during any subsequent calendar year. As a result, the maximum number of Shares pursuant to which Awards may be granted during any calendar year hereunder to any Participant may be greater than the 500,000 Share limit specified above only to the extent that such Shares were not awarded to such Participant during any preceding calendar year. The method of counting such Shares shall conform to any requirements applicable to performance-based compensation under Section 162(m) of the Code or the rules and regulations promulgated thereunder. The maximum amount of dollar-denominated Awards that may be granted to any individual during any calendar year shall not exceed $2,000,000.

SECTION 5. Eligibility.

Any Employee, Consultant or Director shall be eligible to be designated a Participant by the Committee. No individual shall have any right to be granted an Award pursuant to this Plan.

SECTION 6. Awards.

(a) Options

Subject to the provisions of the Plan, the Committee shall have the authority to determine Participants 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, that are not inconsistent with the provisions of the Plan.

(1) Exercise Price. The purchase price per Share purchasable under an Option shall be determined by the Committee at the time the Option is granted, but shall not be less than the Fair Market Value per Share on the effective date of such grant.

(2) Time and Method of Exercise. The Committee shall determine and provide in the Award Agreement or by action subsequent to the grant 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, check acceptable to the Company, Shares already-owned for more than six months (unless such holding requirement is waived by the Committee), Shares issuable upon Option exercise, a “cashless-broker” exercise (through procedures approved by the Committee), other securities or other property, a note, or any combination thereof, having a Fair Market Value on the exercise date equal to the relevant exercise price) in which payment of the exercise price and tax withholding obligation with respect thereto may be made or deemed to have been made. Notwithstanding any other provision of the Plan to the

-6-

contrary, no Participant who is a member of the Board or an “executive officer” of the Company within the meaning of Section 13(k) of the Exchange Act shall be permitted to pay the exercise price of an Option in any method which would violate Section 13(k) of the Exchange Act. The Committee shall also determine the performance or other conditions, if any, that must be satisfied before all or part of an Option may vest and be exercised. No portion of an Option which is unexercisable at termination of the Participant’s employment or service, as applicable, shall thereafter become exercisable, except as may be otherwise provided by the Committee either in the Award Agreement or by action following the grant of the Option.

(3) Incentive Stock Options. An Incentive Stock Option may be granted only to an individual who is an Employee of the Company or any parent or subsidiary corporation (as defined in Section 424 of the Code) at the time the Option is granted and must be granted within 10 years from the date the Plan was approved by the Board or the shareholders, whichever is earlier. To the extent that the aggregate Fair Market Value (determined at the time the respective Incentive Stock Option is granted) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by an individual during any calendar year under all incentive stock option plans of the Company and its parent and subsidiary corporations exceeds $100,000, such Incentive Stock Options shall be treated as a Non-Qualified Stock Option. The Committee shall determine, in accordance with applicable provisions of the Code, Treasury Regulations and other administrative pronouncements, which of a Participant’s Incentive Stock Options will not constitute Incentive Stock Options because of such limitation and shall notify the Participant of such determination as soon as practicable after such determination. No Incentive Stock Option shall be granted to an individual if, at the time the Option is granted, such individual owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or of its parent or subsidiary corporation, within the meaning of section 422(b)(6) of the Code, unless (i) at the time such Option is granted the option price is at least 110% of the Fair Market Value of the Common Stock subject to the Option and (ii) such Option by its terms is not exercisable after the expiration of five years from the date of grant. An Incentive Stock Option shall not be transferable otherwise than by will or the laws of descent and distribution, and shall be exercisable during the Participant’s lifetime only by such Participant or the Participant’s guardian or legal representative. 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.

(4) Substitution of Stock Appreciation Rights. The Committee, in its sole discretion, shall have to right to substitute a SAR for an Option at any time prior to or upon exercise of such Option, subject to the provisions of Section 6(e) hereof; provided that such SAR shall be exercisable for the same number of shares of Stock as such substituted Option would have been exercisable for.

-7-

(b) Restricted Stock.

Subject to the provisions of the Plan, the Committee shall have the authority to determine the Participants 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, including the Performance Criteria or other specified criteria, including the passage of time, if any, under which the Restricted Stock may vest or be forfeited to the Company, and the other terms and conditions of such Awards. However, except as provided in Section 6(b)(3) with respect to waivers, (i) the minimum Restricted Period for a Restricted Stock Award the vesting of which is based on the achievement of Performance Criteria shall not be less than one year and (ii) the minimum Restricted Period for a Restricted Stock Award the vesting of which is based solely on the passage of time shall not be less than three years.

(1) Dividends. 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 or 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, all as determined by the Committee in its discretion, as provided in the Award Agreement.

(2) 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.

(3) Forfeiture and Restrictions Lapse. Except as otherwise determined by the Committee or the terms of the Award Agreement, upon a Participant’s termination of employment or service (as determined under criteria established by the Committee) 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, upon or in connection with a Qualifying Event, waive in whole or in part any or all remaining restrictions with respect to such Participant’s Restricted Stock; provided, however, if the Award is intended to qualify as performance based compensation under Section 162(m) of the Code, such waiver may be only in compliance with the requirements of Section 162(m) of the Code. 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.

(4) Restrictions. Restricted Stock shall be subject to such restrictions on transferability and other restrictions as the Committee may impose (including, without limitation, restrictions on the right to vote Restricted Stock or the right to receive dividends on the Restricted Stock). These restrictions may lapse separately or in combination at such times, pursuant to such circumstances, in such installments, or otherwise, as the Committee determines at the time of the grant of the Award or thereafter. During the Restricted Period, Restricted Stock will be subject to such limitations on transfer as necessary to comply with Section 83 of the Code.

(c) Performance Awards.

The Committee shall have the authority to determine the Participants who shall receive a Performance Award, which shall be denominated as a cash amount at the time of grant and confer on the Participant the right to receive all or part of such Award upon the achievement of such performance goals (based on the Performance Criteria or any other specified criteria) during such performance periods as the Committee shall establish with respect to the Award. However, except as provided in Section 6(c)(3) with respect to waivers, the minimum performance period shall not be less than one year. The Committee, in its discretion, may determine whether an Award is to qualify as performance-based compensation as described in Section 162(m) (4) (C) of the Code.

(1) 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 Performance Criteria or other criteria upon which the performance goals are to be based, the length of any performance period and the amount of any Performance Award.

(2) Payment of Performance Awards. Performance Awards may be paid (in cash and/or in Shares, in the sole discretion of the Committee) in a lump sum or in installments following the close of the performance period, or at such later deferral date elected by the Participant, in accordance with procedures established by the Committee with respect to such Award.

(3) Forfeiture and Restrictions Lapse. Except as otherwise determined by the Committee or the terms of the Award Agreement that granted the Performance Award, upon a Participant’s termination of employment or service, as applicable (as determined under criteria established by the Committee) for any reason during the applicable Restricted Period, all Performance Awards shall be forfeited by the Participant and re-acquired by the Company. The Committee may, upon or in connection with a Qualifying Event, waive in whole or in part any or all remaining restrictions with respect to such Participant’s Performance Award; provided, however, if the Award is intended to qualify as performance based compensation under Section 162(m) of the Code, such waiver may be only in compliance with the requirements of Section 162(m) of the Code. Unrestricted Shares, evidenced in such manner as the Committee shall deem appropriate, shall be issued to the holder of Performance Awards promptly after the applicable restrictions have lapsed or otherwise been satisfied.

(d) Phantom Shares.

The Committee shall have the authority to grant Awards of Phantom Shares to Participants upon such terms and conditions as the Committee may determine.

(1) Terms and Conditions. Each Phantom Share Award shall constitute an agreement by the Company to issue or transfer a specified number of Shares or pay an amount of cash equal to the Fair Market Value of a specified number of Shares, or a combination thereof to the Participant in the future, subject to the fulfillment during the

-9-

Restricted Period of such conditions, including those linked to the Performance Criteria or other specified criteria, including the passage of time, 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 Phantom Shares and shall not have any right to vote such shares.

(2) Dividend Equivalents. Any Phantom Share award may provide, in the discretion of the Committee, that any or all dividends or other distributions paid on Shares during the Restricted Period be credited in a cash bookkeeping account (with or without interest) or that equivalent additional Phantom Shares be awarded, which account or Phantom Shares may be subject to the same restrictions as the underlying Award or such other restrictions as the Committee may determine.

(3) Forfeiture and Restrictions Lapse. Except as otherwise determined by the Committee or set forth in the Award Agreement, upon a Participant’s termination of employment or service (as determined under criteria established by the Committee) for any reason during the applicable Restricted Period, all Phantom Shares shall be forfeited by the Participant. The Committee may, upon or in connection with a Qualifying Event, waive in whole or in part any or all remaining restrictions with respect to such Participant’s Phantom Shares; provided, however, if the Award is intended to qualify as performance based compensation under Section 162(m) of the Code, such waiver may be only in compliance with the requirements of Section 162(m) of the Code.

(4) Payment of Phantom Shares. Phantom Shares may be paid (in cash and/or in Shares, in the sole discretion of the Committee) in a lump sum or in installments following the close of the Restricted Period, or at such later deferral date elected by the Participant, in accordance with procedures established by the Committee with respect to such Award.

(e) SARs.

(g) Substitute Awards.

Awards may be granted under the Plan in substitution of similar awards held by individuals who become Employees, Consultants or Directors as a result of a merger, consolidation or acquisition by the Company or a Subsidiary of another entity or the assets of another entity. Such substitute awards may have exercise prices less than the Fair Market Value of a Share on the date of such substitution.

(h) General.

(1) 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, any other Award granted under the Plan or any award granted under any other plan of the Company or any Subsidiary.

(2) Limits on Transfer of Awards.

(A) Except as provided in paragraph (C) below, 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 legal representative as determined by the Committee.

(C) To the extent specifically approved in writing by the Committee, an Award (other than an Incentive Stock Option) may be transferred to immediate family members or related family trusts, limited partnerships or similar entities or other Persons on such terms and conditions as the Committee may establish or approve.

-11-

(3) Terms of Awards. The term of each Award shall be for such period as may be determined by the Committee; provided, that in no event shall the term of any Award exceed a period of 10 years from the date of its grant.

(4) Share Certificate. All certificates for Shares or other securities of the Company or any Subsidiary 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.

(5) 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.

(6) 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 (including, without limitation, any exercise price or tax withholding) 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.

(i) Performance Based Compensation.

The Committee shall determine which Awards are intended by the Committee to qualify as “performance-based compensation” as described in Section 162(m)(4)(C) of the Code. The Committee shall establish performance goals applicable to those Awards based upon the attainment of such target levels of one or more of the Performance Criteria, over one or more periods of time, which may be of varying and overlapping durations, as the Committee may select. The Performance Criteria shall be subject to adjustment for changes in accounting standards required by the Financial Accounting Standards Board after the goal is established, and, to the extent provided for in the Award Agreement, shall be subject to adjustment for specified significant extraordinary items or events. In this regard, performance goals based on stock price shall be proportionately adjusted for any changes in the price due to a stock split. Performance Criteria may be absolute, relative to one or more other companies, or relative to one

-12-

or more indexes, and may be contingent upon future performance of the Company or any Subsidiary, division, unit or product line thereof. A performance goal need not be based upon an increase or positive result under a Performance Criteria and could, for example, be based upon limiting economic losses or maintaining the status quo. Which Performance Criteria to be used with respect to any grant, and the weight to be accorded thereto if more than one factor is used, shall be determined by the Committee, in its sole discretion, at the time of grant. To the extent necessary to comply with the qualified performance-based compensation requirements of Section 162(m)(4)(C) of the Code, following the completion of each specified performance period, the Committee shall certify in writing whether the applicable performance goals have been achieved for such performance period. In determining the amount earned by a Participant, the Committee shall have the right to reduce or eliminate (but not to increase) the amount payable at a given level of performance to take into account additional factors that the Committee may deem relevant to the assessment of individual or corporate performance for the performance period. Notwithstanding any other provision of the Plan, any Award which is intended to constitute qualified performance-based compensation shall be subject to any additional limitations set forth in Section 162(m) of the Code (including any amendment to Section 162(m) of the Code) or any regulations or rulings issued thereunder that are requirements for qualification as qualified performance-based compensation as described in Section 162(m)(4)(C) of the Code, and the Plan shall be deemed amended to the extent necessary to conform to such requirements.

Except to the extent prohibited by applicable law and unless otherwise expressly provided in an Award Agreement or in the Plan:

(1) Amendments to the Plan. The Board or the Committee may amend, alter, suspend, discontinue, or terminate the Plan without the consent of any stockholder, Participant, other holder or beneficiary of an Award, or other Person; provided, however, 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 that may be issued under the Plan, except as provided in Section 4(c) of the Plan, or (ii) permit the exercise price of any outstanding Option or SAR that is “underwater” to be reduced or for an “underwater” Option or SAR to be cancelled and replaced with a new Award.

(2) Amendments to Awards. Subject to Paragraph (1) above and Section 3(b), the Committee may waive any conditions or rights under, amend any terms of, or alter any Award theretofore granted, provided no change in any Award shall adversely affect the rights of a Participant under the Award 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 other than an acceleration of vesting or payment upon the Participant’s death, disability or change of control of the Company, shall be authorized to the extent such adjustment would cause the Award to fail to so qualify.

SECTION 8. General Provisions.

(a) No Rights to Awards.

No Participant or other Person shall have any claim to be granted any Award, there is no obligation for uniformity of treatment of Participants, or holders or beneficiaries of Awards and the terms and conditions of Awards need not be the same with respect to each recipient.

(b) Tax Withholding.

The Company or any Subsidiary is authorized to withhold from any Award, from any payment due or transfer made under any Award or from any compensation or other amount owing to a Participant the amount (in cash, Shares, or other property) of any applicable taxes required to be withheld by the Company or Subsidiary in respect of the Award, its exercise, the lapse of restrictions thereon, or any payment or transfer under the Award and to take such other action as may be necessary in the opinion of the Company to satisfy all of its obligations for the payment of such taxes. In addition, the Committee may provide, in an Award Agreement, that the Participant may direct the Company to satisfy such Participant’s tax withholding obligations through the withholding of Shares otherwise to be acquired upon the exercise or payment of such Award, but only to the extent such withholding does not cause a charge to the Company’s financial earnings.

(c) No Right to Employment or Retention.

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 Subsidiary or under any other service contract with the Company or any Subsidiary, or to remain on the Board. Further, the Company or a Subsidiary may at any time dismiss a Participant from employment or terminate any contractual agreement or relationship with any Consultant, free from any liability or any claim under the Plan, with or without cause, unless otherwise expressly provided in the Plan, in any Award Agreement or any other agreement or contract between the Company or a Subsidiary and the affected Participant. If a Participant’s employer ceases to be a Subsidiary, such Participant shall be deemed to have terminated employment for purposes of the Plan, unless specifically provided otherwise in the Award Agreement.

(d) Unusual Transactions or Events.

In the event of any distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, reorganization, merger, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other similar corporate transaction or event or any unusual or nonrecurring transactions or events affecting the Company, any affiliate of the Company, or the financial statements of the Company or any affiliate, or of changes in applicable laws, regulations or accounting principles, and whenever the Committee determines that action is appropriate in order to prevent the dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to any Award under the Plan, to facilitate such transactions or events or to give effect to such changes in laws, regulations or principles, the Committee, in its sole discretion and on such terms and conditions as it deems appropriate, either by amendment of the terms of any outstanding Awards or by action taken prior to the occurrence of such transaction or event and either automatically or upon the Participant’s request, is hereby authorized to take any one or more of the following actions:

-14-

(1) To provide for either (A) termination of any such Award in exchange for an amount of cash, if any, equal to the amount that would have been attained upon the exercise of such Award or realization of the Participant’s rights (and, for the avoidance of doubt, if as of the date of the occurrence of the transaction or event described in this Section 8(d) the Committee determines in good faith that no amount would have been attained upon the exercise of such Award or realization of the Participant’s rights, then such Award may be terminated by the Company without payment) or (B) the replacement of such Award with other rights or property selected by the Committee in its sole discretion;

(2) To provide that such Award be assumed by the successor or survivor corporation, or a parent or subsidiary thereof, or shall be substituted for by similar options, rights or awards covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of shares and prices; and

(3) To make adjustments in the number and type of shares of common Stock (or other securities or property) subject to outstanding Awards, and in the number and kind of outstanding Awards and/or in the terms and conditions of (including the grant or exercise price), and the criteria included in, outstanding Awards and Awards which may be granted in the future;

(4) To provide that such Award shall be exercisable or payable or fully vested with respect to all shares covered thereby, notwithstanding anything to the contrary in the Plan or the applicable Award Agreement; and

(5) To provide that the Award cannot vest, be exercised or become payable after such event.

(e) 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 Texas and applicable federal law.

(f) 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 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.

-15-

(g) Other Laws.

The Committee may refuse to issue or transfer any Shares or other consideration under an Award, permit the exercise of an Award and/or the satisfaction of its tax withholding obligation in the manner elected by the Participant, holder or beneficiary if, acting in its sole discretion, it determines that the issuance of transfer or such Shares or such other consideration, the manner of exercise or satisfaction of the tax withholding obligation might violate any applicable law or regulation, including without limitation, the Sarbanes-Oxley Act, 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 or refused, as the case may be, to the relevant Participant, holder or beneficiary.

(h) No Trust or Fund Created.

Neither the Plan nor the 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 Subsidiary and a Participant or any other Person. To the extent that any Person acquires a right to receive payments from the Company or any Subsidiary pursuant to an Award, such right shall be no greater than the right of any general unsecured creditor of the Company or any Subsidiary.

(i) 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.

(j) Headings.

Headings are given to the Section 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 9. Effective Date of Plan.

The Plan shall become effective as of the later of the date (i) it is approved by the stockholders of the Company and (ii) the merger between National-Oilwell Inc. and Varco International Inc. is effective. No Awards may be made prior to the effective date of the Plan.

SECTION 10. Forfeiture in Certain Circumstances (“Clawback”).

The Committee may, at its sole discretion, terminate any Award if it determines that the recipient of the Award has engaged in material misconduct. For purposes of this Clawback provision, material misconduct includes conduct adversely affecting the Company’s financial condition, results of operations, or conduct which constitutes fraud or theft of Company assets, any of which require the Company to make a restatement of its reported financial statements. The Committee may also specify other conduct requiring the Company to make a restatement of its

-16-

publicly reported financial statements as constituting material misconduct in future Award Agreements. If any material misconduct results in any error in financial information used in the determination of compensation paid to the recipient of an Award and the effect of such error is to increase the payment amount pursuant to an Award, the Committee may also require the recipient to reimburse the Company for all or a portion of such increase in compensation provided in connection with any such Award. In addition, if there is a material restatement of the Company’s financial statements that affects the financial information used to determine the compensation paid to the recipient of the Award, then the Committee may take whatever action it deems appropriate to adjust such compensation.

SECTION 11. Term of the Plan.

No Award shall be granted under the Plan after September 13, 2014, which is the 10th anniversary of the date this Plan was first adopted by the Board. However, unless otherwise expressly provided in the Plan or in an applicable Award Agreement, any Award granted prior to such termination, 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 such Award, shall extend beyond such termination date.
