Amendment and Termination. Except to the extent prohibited by applicable law or the rules of the principal securities market on which the shares are traded and unless otherwise expressly provided in an Option agreement or in the Plan: (i) 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 Option, or other Person. (ii) Amendments to Options. The Committee may waive any conditions or rights under, amend any terms of, or alter any Option theretofore granted, provided no change, other than pursuant to Section 7(iii), in any Option shall materially reduce the benefit to Participant without the consent of such Participant.

SECTION 8. Change in Control. Notwithstanding any other provision of this Plan or an Option agreement to the contrary, in the event of a Change in Control of the Company all outstanding Options automatically shall become fully vested immediately prior to such Change in Control (or such earlier time as set by the Committee).

In the event of a Change in Control, the Committee, in its discretion, may (i) provide for the purchase of the Option for an amount of cash or other property that could have been received upon the exercise of the Option, (ii) adjust the terms of the Option in a manner determined by the Committee to reflect the Change in Control, (iii) cause the Option to be assumed, or new rights substituted therefor, by another entity, or (iv) make such other provision as the Committee may consider equitable and in the best interests of the Company, including, without limitation, providing for the termination of the Option to the extent not exercised. SECTION 9. General Provisions. (a) No Rights to Options. No Employee, Consultant or Director shall have any claim to be granted any Option, and there is no obligation for uniformity of treatment of Participants. The terms and conditions of Options need not be the same with respect to each recipient. (b) No Right to Employment. The grant of an Option 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 -7- 8 liability or any claim under the Plan, unless otherwise expressly provided in the Plan or in any Option Agreement. (c) 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. (d) Severability. If any provision of the Plan or any Option is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any Person or Option, or would disqualify the Plan or any Option 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 Option, such provision shall be stricken as to such jurisdiction, Person or Option and the remainder of the Plan and any such Option shall remain in full force and effect. (e) Other Laws. The Committee may refuse to issue or transfer any Shares or other consideration under an Option 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. (f) No Trust or Fund Created. Neither the Plan nor the Option 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 Option, such right shall be no greater than the right of any general unsecured creditor of the Company or any Affiliate. (g) No Fractional Shares. No fractional Shares shall be issued or delivered pursuant to the Plan or any Option, 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 canceled, terminated, or otherwise eliminated. (h) 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 the date of its approval by the Board. SECTION 11. Term of the Plan. No Option shall be granted under the Plan after the 10th anniversary of the date the Plan is adopted by the Board. However, unless otherwise expressly provided in the Plan or in an applicable Option agreement, any Option granted prior to such termination, and the authority of the Board or -8- 9 the Committee to amend, alter, adjust, suspend, discontinue, or terminate any such Option or to waive any conditions or rights under such Option, shall extend beyond such termination date. -9-
