The Company shall provide the benefits described in this subsection for a period terminating eighteen (18) months after the Date of Termination. An election by you to terminate for Good Reason shall not be deemed a voluntary termination of employment by you for purposes of this Agreement or of any plan or practice of the Company. At the end of the period of coverage, you shall have the option to have assigned to you, at no cost and with no apportionment of prepaid premiums, any assignable insurance policy owned by the Company or relating specifically to you.

8.6. Base Salary Defined. For purposes of this Agreement, the term “Base Salary” shall include any amounts deducted pursuant to Sections 125 and 401(k) of the Internal Revenue Code of 1986, as amended, (the “Code”).

8.8. Parachute Payment. Notwithstanding anything in this Section 8 to the contrary, if you are a “Disqualified Individual” (as defined in Section 280G(c) of the Code) and the payment provided for in this Section 8, together with any other payments which you have the right to receive from the Company (including without limitation the payments under Section 8.4 and the acceleration of vesting of equity awards under Company equity inventive plans) would constitute a “Parachute Payment” (as defined in Section 280G(b)(2) of the Code), the total amounts received by you from the Company which constitute Parachute Payments shall be reduced to be one dollar ($1.00) less than three (3) times your base amount (as defined in Section 280G of the Code) so that no portion of such amounts received by you shall be subject to the excise tax

- 7 -

imposed by Section 4999 of the Code if and only if (i) such reduction in the amount paid produces a better net after tax position (taking into account any applicable excise tax under Section 4999 of the Code and any applicable income tax) than the total payment provided for herein and (ii) there are no other amounts receivable by you from the Company which, by their terms, may not be reduced such that no portion of such amounts received by you shall be subject to the excise tax under Section 4999 of the Code.

8.9. Tax Issues.

12. INDEPENDENT ELEMENTS. The parties acknowledge that the promises and covenants contained in Sections 9 and 10 above are essential independent elements of this Agreement and that, but for Executive agreeing to comply with them, the Company would not employ Executive. Accordingly, the existence or assertion of any claim by Executive against the Company, whether based on this Agreement or otherwise, shall not operate as a defense to the Company’s enforcement of the promises and covenants in Sections 9 and 10. An alleged or actual breach of the Agreement by the Company will not be a defense to enforcement of any such promise or covenant, or other obligations of Executive to the Company. The promises and covenants in Sections 9 and 10 will remain in full force and effect whether Executive is terminated by the Company or voluntarily resigns.

13. INDEMNIFICATION. The Company’s Bylaws provide for indemnification of directors and officers of the Company, including you, during the full term of this Agreement, and at all times to provide adequate insurance for such purposes.

You shall be indemnified to the full extent permitted by law, against any and all costs, expenses, judgments, penalties (including excise and similar taxes and punitive damages, fines, settlements and reasonable expenses (including without limitation, attorneys’ fees)) incurred (or reasonably anticipated to be incurred) by you in connection with such Proceeding. Notwithstanding the above, the Company shall not be obligated to indemnify you in connection with any Proceeding or claim initiated by you against the Company or its subsidiaries, officers, directors, or employees.

14. SUCCESSOR’S BINDING AGREEMENT.

(i) The Company will cause any entity that becomes a Successor (as hereinafter defined) to expressly assume the Company’s obligations under this Agreement and acknowledge that the Successor is contractually bound to perform all of such obligations. Failure of such entity to furnish such assumption and acknowledgement by the time such entity becomes a Successor shall constitute Good Reason for termination by you of your employment if a Change in Control

- 11 -

of the Company occurs or has occurred. For purposes of this Agreement, “Successor” shall mean any entity that succeeds to, or has the practical ability to control (either immediately or with the passage of time), the Company’s business directly, by merger or consolidation, or indirectly, by purchase of the Company’s voting securities or otherwise.

(ii) This Agreement shall inure to the benefit of and be enforceable by your personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.

15. TAXES. All payments to be made to you under this Agreement will be subject to required withholding of applicable federal, state and local taxes.

16. SECTION 409A.

16.1. Purpose. This section is intended to help ensure that compensation paid or delivered to you pursuant to this Agreement either is paid in compliance with, or is exempt from, Section 409A of the Code and the rules and regulations promulgated thereunder (collectively, “Section 409A”). However, the Company does not warrant that all compensation paid or delivered to you will be exempt from, or paid in compliance with, Section 409A.

16.2. Interpretation. Notwithstanding anything herein to the contrary, this Agreement is intended to be interpreted and applied so that the payments and benefits set forth herein shall either be exempt from the requirements of Section 409A, or shall comply with the requirements of Section 409A, and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be exempt from or in compliance with Section 409A. For purposes of the application of Treas. Reg. § 1.409A-1(b)(4) (or any successor provision), each payment under this Agreement (including any installment payments) shall be deemed a separate payment.

16.3. Amounts Payable On Account of Termination. For the purposes of determining when amounts otherwise payable on account of your termination of employment under this Agreement will be paid, which amounts become due because of your termination of employment, “termination of employment” or words of similar import, as used in this Agreement, shall be construed as the date that you first incur a “separation from service” for purposes of Section 409A on or following termination of employment. Notwithstanding any provision in this Agreement or elsewhere to the contrary, if on your Date of Termination you are deemed to be a “specified employee” within the meaning of Section 409A, any payments or benefits due upon a termination of your employment under any arrangement that constitutes a “deferral of compensation” within the meaning of Section 409A (whether under this Agreement, any other plan, program, payroll practice or any equity grant) and which do not otherwise qualify under the exemptions under Treas. Reg. § 1.409A-1 (including, without limitation, the short-term deferral exemption and the permitted payments under Treas. Reg. § 1.409A-1(b)(9)(iii)(A)), shall be delayed and paid or provided to you in a lump sum (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) on the earlier of (i) the date which is six months and one day after your “separation from service” (as such term is defined in Section 409A of the Code) for any reason other than death, and (ii) the date of your death, and any remaining payments and benefits shall be paid or provided in accordance with the normal payment dates specified for such payment or benefit.

16.4. Reimbursements. With respect to any expense, reimbursement or in-kind benefit provided pursuant to this Agreement that constitutes a “deferral of compensation” within the meaning of Section 409A, (i) the expenses eligible for reimbursement or in-kind benefits provided to you must be incurred during the Term (or applicable survival period), (ii) the amount of expenses eligible for reimbursement or in-kind benefits provided to you during any calendar year will not affect the amount of expenses eligible for reimbursement or in-kind benefits provided to you in any other calendar year, (iii) the reimbursements for expenses for which you are entitled to be reimbursed shall be made on or before the last day of the calendar year following the calendar year in which the applicable expense is incurred, and (iv) the right to payment or reimbursement or in-kind benefits hereunder may not be liquidated or exchanged for any other benefit.

17. SURVIVAL. Any termination of this Agreement and Executive’s employment shall not release either the Company or Executive from their respective obligations to the date of termination nor from the provisions of this Agreement that, by necessary or reasonable implication, are intended to apply after such termination, including without limitation the provisions of Section 9. Furthermore, neither the termination of this Agreement nor the termination of Executive’s employment hereunder shall affect, limit or modify in any manner the existence or enforceability of any other written agreement between Executive and the Company, even if such other agreements provide employment-related benefits to Executive.

18. NOTICES. Notices and all other communications provided for herein shall be in writing and shall be deemed to have been duly given when delivered or mailed by certified or registered mail, return receipt requested, postage prepaid addressed to the respective addresses set forth on the signature page of this Agreement or to such other address as either party may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt.

19. MISCELLANEOUS.

No waiver at any time by either party hereto of the breach of any condition or provision of this Agreement, or of compliance by the other party with the same, shall be deemed a waiver of any other condition or provision at the same or at any other time. No party hereto shall by any act (except by written instrument pursuant to this Section), delay, indulgence, omission or otherwise be deemed to have waived any right, power, privilege or remedy hereunder or to have acquiesced in any default in or breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of any party hereto, any right, power, privilege or remedy hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power, privilege or remedy hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power, privilege or remedy. No remedy set forth in this Agreement or otherwise conferred upon or reserved to any party shall be considered exclusive of any other remedy available to any party, but the same shall

No agreement or representation still in effect, oral or otherwise, express or implied, with respect to the subject matter hereof has been made by either party other than (i) those set forth expressly in this Agreement or (ii) those in any equity award agreements. Upon termination of your employment, in the event of any conflict between the terms of this Agreement and the terms of any other agreements between you and the Company, this Agreement shall be controlling. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the State of Texas, without regard to principles of conflicts of laws. Neither party to this Agreement may assign this Agreement or any or all of its rights or obligations hereunder without the prior written consent of the other party hereto.

This Agreement and the agreements contemplated hereby or executed in connection herewith (i) constitute the entire agreement of the parties hereto regarding the subject matter hereof, and (ii) supersede all prior employment agreements, both written and oral, among the parties hereto, or any of them.
