(h)                                 Reaffirm Obligations.  Upon termination of his employment with the Company, Executive, if requested by Company, shall reaffirm in writing Executive’s recognition of the importance of maintaining the confidentiality of the Company’s Confidential Information and proprietary information, and reaffirm any other obligations set forth in this Agreement.

(i)                                     Prior Disclosure.  Executive represents and warrants that he has not used or disclosed any Confidential Information he may have obtained from the Company prior to signing this Agreement, in any way inconsistent with the provisions of this Agreement.

(j)                                     Confidential Information of Prior Companies.  Executive will not disclose or use during the period of his employment with the Company any proprietary or Confidential Information or copyrighted works which Executive may have acquired because of employment with an employer other than the Company or acquired from any other third party, whether such information is in Executive’s memory or embodied in a writing or other physical form.

(k)                                  Breach.  Executive agrees that any breach of Sections 5(a), (c), (d), (e) or (f) above cannot be remedied solely by money damages, and that in addition to any other remedies the Company may have, the Company is entitled to obtain injunctive relief against Executive.  Nothing herein, however, shall be construed as limiting Company’s right to pursue any other available remedy at law or in equity, including recovery of damages and termination of this Agreement and/or any payments that may be due pursuant to this Agreement.

(l)                                     Right to Enter Agreement.  Executive represents and covenants to Company that he has full power and authority to enter into this Agreement and that the execution of this Agreement will not breach or constitute a default of any other agreement or contract to which he is a party or by which he is bound.

(m)                               Extension of Post-Employment Restrictions.  In the event Executive breaches Sections 5(c), (d), or (e) above, the restrictive time periods contained in those provisions will be extended by the period of time Executive was in violation of such provisions.  The restrictive time periods contained in Sections 5(c), (d), or (e) shall likewise be extended during any time period

12

in which litigation is pending by Executive against the Company or by the Company against Executive with regard to the enforcement of the provisions of Section 5 of this Agreement.

(n)                                 Enforceability.  The agreements contained in Section 5 are independent of the other agreements contained herein.  Accordingly, failure of the Company to comply with any of its obligations outside of this Section does not excuse Executive from complying with the agreements contained herein.

(o)                                 Ownership in Publicly Traded Company.  The Executive’s ownership in a publicly traded business entity in competition with the Company shall not be regarded by the Parties as employment in a competitive activity in violation of this Section, provided that Executive’s ownership interest in such company is passive and constitutes no more than a two percent (2%) ownership in the stock of such publicly traded company.

6.                                      Assignment.  This Agreement cannot be assigned by Executive.  The Company may assign this Agreement only to a successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and assets of the Company provided such successor expressly agrees in writing reasonably satisfactory to Executive to assume and perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession and assignment had taken place.  The Company shall obtain the assumption and performance of this Agreement by any such successor; provided, however, that such commitment by the Company (including a failure to satisfy such commitment) shall not give Executive the right to object to or enjoin any transaction among the Company, any of its affiliates, and any such successor.  To the extent a failure by the Company to satisfy the foregoing commitment constitutes a material breach of this Agreement and to the extent not cured in accordance with Section 4(a)(4), such failure shall constitute “Good Reason” pursuant to Section 4(a)(4)(iv).

7.                                      Binding Agreement.  Executive understands that his obligations under this Agreement are binding upon Executive’s heirs, successors, personal representatives, and legal representatives.

8.                                      Survivability.  The provisions of this Agreement which call for performance after the end of the Term, including, without limitation, the agreements contained in Section 5, shall survive the termination of this Agreement for any reason.

9.                                      Notices.  All notices pursuant to this Agreement shall be in writing and sent certified mail, return receipt requested, addressed as set forth below, or by delivering the same in person to such party, or by transmission by facsimile to the number set forth below.  Notice deposited in the United States Mail, mailed in the manner described herein above, shall be effective upon deposit.  Notice given in any other manner shall be effective only if and when received:

13

10.                               Waiver.  No waiver by either party to this Agreement of any right to enforce any term or condition of this Agreement, or of any breach hereof, shall be deemed a waiver of such right in the future or of any other right or remedy available under this Agreement.

11.                               Severability.  If any provision of this Agreement is determined to be void, invalid, unenforceable, or against public policy, such provisions shall be deemed severable from the Agreement, and the remaining provisions of the Agreement will remain unaffected and in full force and effect.

12.                               Arbitration.  Except as provided in subsection (d) below, in the event any dispute arises out of or related to Executive’s employment with or by the Company, or separation/termination therefrom, which cannot be resolved by the Parties to this Agreement, such dispute shall be submitted to final and binding arbitration.  Except as provided in subsection (d) below, arbitration of such disputes is mandatory and in lieu of any and all civil causes of action and lawsuits either party may have against the other arising out of Executive’s employment with the Company, or separation therefrom.

(a)                                  The arbitration shall be conducted in accordance with the National Rules for the resolution of Employment Disputes of the American Arbitration Association (“AAA”).  If the Parties cannot agree on an arbitrator, a list of seven (7) arbitrators will be requested from AAA, and the arbitrator will be selected using alternate strikes with Executive striking first.  Subject to subsection (c) below, cost of the arbitration will be shared equally by Executive and Company.  Such arbitration shall be held in Houston, Texas.

(b)                                 Judgment on the award rendered by the arbitrator may be entered in any court having jurisdiction thereof by the filing of a petition to enforce the award.  Costs of filing may be recovered by the party that initiates such action to have the award enforced.

(c)                                  The Company shall promptly reimburse Executive for all eligible, reasonable costs and expenses incurred in connection with any dispute, controversy, or claim submitted to binding arbitration in accordance with this Section in an amount up to, but not exceeding an amount equal to twenty percent (20%) of Executive’s Base Salary per taxable year of Executive, unless Executive was terminated for Cause, in which event Executive shall not be entitled to reimbursement unless and until it is determined he was terminated other than for Cause.  To be eligible for reimbursement under this subsection (c), (1) the expenses must be incurred during the period beginning on the Effective Date and ending on the date that is ten years after the end of the Term and (2) the expenses must be submitted to the Company for reimbursement within 90 days after the end of the taxable year of Executive in which the expenses were incurred.  Amounts eligible for reimbursement shall be paid to Executive before the last day of the taxable year of Executive following the taxable year in which the expenses were incurred.  The amount of expenses eligible for

14

reimbursement during Executive’s taxable year may not affect the expenses eligible for reimbursement in any other taxable year of Executive.  Executive’s right to reimbursement under this subsection (c) may not be assigned, alienated, or exchanged for any other benefit.

(d)                                 It is specifically agreed by the Parties that any enforcement action by the Company against Executive for equitable relief, including, but not limited to, injunctive relief under Section 5 of this Agreement shall not be subject to this Section requiring arbitration and that the Company shall not be required to seek arbitration against Executive for any purported violation by Executive of his obligations under Section 5 of this Agreement.

13.                               Entire Agreement.  The terms and provisions contained herein shall constitute the entire agreement between the Parties with respect to Executive’s employment with Company during the time period covered by this Agreement.  This Agreement replaces and supersedes any and all existing agreements entered into between Executive and the Company relating generally to the same subject matter, if any, and shall be binding upon Executive’s heirs, executors, administrators, or other legal representatives or assigns.

14.                               Modification of Agreement.  This Agreement may not be changed or modified or released or discharged or abandoned or otherwise terminated, in whole or in part, except by an instrument in writing signed by Executive and an officer or other authorized executive of Company.

15.                               Effective Date.  It is understood by the Parties that this Agreement shall be effective as of the Effective Date when signed by both the Company and Executive.

16.                               Governing Law.  This Agreement shall be governed by and construed in accordance with the laws of the State of Texas without regard to conflict of laws principles.

17.                               Jurisdiction and Venue.  With respect to any litigation regarding this Agreement, Executive agrees to venue in the state or federal courts in Harris County, Texas, and agrees to waive and does hereby waive any defenses and/or arguments based upon improper venue and/or lack of personal jurisdiction.  By entering into this Agreement, Executive agrees to personal jurisdiction in the state and federal courts in Harris County, Texas.

18.                               Compliance With Section 409A.

(a)                                  Delay in Payments. Notwithstanding anything to the contrary in this Agreement, (i) if upon the Termination Date, Executive is a “specified employee” within the meaning of Code Section 409A and the deferral of any amounts otherwise payable under this Agreement as a result of Executive’s termination of employment is necessary in order to prevent any accelerated or additional tax to Executive under Code Section 409A, then the Company will defer the payment of any such amounts hereunder until the date that is six (6) months following the date of Executive’s termination of employment with the Company, at which time any such delayed amounts will be paid to Executive in a single lump sum, with interest from the date otherwise payable at the United States prime rate as published in the “Money Rates” section of The Wall Street Journal on the first publication date coincident with or immediately following the Termination Date, and (ii) if any other payments of money or other benefits due to Executive hereunder could cause the application of

15

an accelerated or additional tax under Code Section 409A, such payments or other benefits shall be deferred if deferral will make such payment or other benefits compliant under Code Section 409A and if this subsection (ii) does not otherwise cause the application of an accelerated or additional tax under Code Section 409A.

(b)                                 Separation from Service.  A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” (within the meaning of Code Section 409A).

(c)                                  Separate Payments.  For purposes of Code Section 409A, each payment under Section 4 (and each other severance plan payment) will be treated as a separate payment.

(d)                                 Overall Compliance.  To the extent any provision of this Agreement or any omission from the Agreement would (absent this Section 18(d)) cause amounts to be includable in income under Code Section 409A(a)(1), the Agreement shall be deemed amended to the extent necessary to comply with the requirements of Code Section 409A; provided, however, that this Section 18(d) shall not apply and shall not be construed to amend any provision of the Agreement to the extent this Section 18(d) or any amendment required thereby would itself cause any amounts to be includable in income under Code Section 409A(a)(1).

(e)                                  Reformation. If any provision of this Agreement would cause Executive to incur any additional tax under Code Section 409A, the Parties will in good faith attempt to reform the provision in a manner that maintains, to the extent possible, the original intent of the applicable provision without violating the provision of Code Section 409A.

(f)                                    Code Section 409A Excise Tax Gross Up.  If the terms of this Agreement (as may be modified under Sections 18(d) and 18(e)) or any action or omission by the Company in its performance under this Agreement, causes any payment or benefit received or to be received by Executive from the Company pursuant to this Agreement (the “Agreement Payments”) to be subject to the excise tax and additional interest imposed by Code Section 409A(a)(1)(B) (the “409A Excise Tax”), the Company shall pay Executive, at the time specified below, an additional amount (the “409A Gross-Up Payment”) such that the net amount that Executive retains, after deduction of the 409A Excise Tax on the Agreement Payments; any federal, state, and local income and employment taxes; any additional 409A Excise Taxes upon the 409A Gross-Up Payment; and any interest, penalties, or additions to tax payable by Executive with respect thereto, shall be equal to the total present value (using the applicable federal rate (as defined in Section 1274(d) of the Code) in such calculation) of the Agreement Payments at the time such payments are to be made.  Payment of such additional amount shall occur on or before the earlier to occur of (i) the date which the Company is required to withhold any such taxes and (ii) the date on which Executive remits such taxes to the Internal Revenue Service (to the extent not withheld).  For purposes of determining the amount of the 409A Gross-Up Payment, Executive shall be deemed to pay federal income taxes at the highest marginal rates of federal income taxation applicable to individuals in the calendar year in which the 409A Gross-Up Payment is to be made and state and local income taxes at the highest marginal rates of taxation applicable to individuals as are in effect in the state and locality of Executive’s residence in the calendar year in which the 409A Gross-Up Payment is to be made, net of the maximum

16

reduction in federal income taxes that can be obtained from deduction of such state and local taxes, taking into account any limitations applicable to individuals subject to federal income tax at the highest marginal rates.  This Section 18(f) does not require the Company to pay, reimburse, or gross up Executive with respect to excise taxes imposed under any other section of the Code or under state or local law.
