Any such termination shall accelerate the Transition Period and the day of such termination shall be deemed to be the last day of the Transition Period. Executive’s employment with Company during the Transition Period shall be employment at will, but the Company may not terminate Executive prior to the end of the Transition Period (other than for “cause” (as defined in the Employment Agreement)). Unless earlier terminated, Executive’s employment with the Company shall be terminated on the close of business of the last day of the Transition Period (the “Termination Date”) and all terms and conditions of, and payments in connection with, Executive’s termination of employment shall be governed by the Separation Agreement and Release in the form attached hereto as Exhibit I (the “Separation Agreement”).

9. No Other Claims; No Unlawful Conduct. Executive represents that Executive has not filed or authorized the filing of any complaints, charges or lawsuits against the Company and/or its Affiliates with any federal, state or local court, governmental agency, or administrative agency, and that if, unbeknownst to Executive, any such complaint has been filed on Executive’s behalf, Executive will use Executive’s best efforts to cause it to be withdrawn immediately and dismissed with prejudice. Executive also represents that Executive has not engaged in, and is not aware of, any unlawful conduct in relation to the business of the Company and/or its Affiliates.

10.1 The Parties shall keep strictly confidential all the terms and conditions of this Agreement and shall not disclose them to any person other than legal and/or financial advisors, government officials who seek such information in the course of their official duties, individuals at the Company and/or its Affiliates, and Executive’s spouse, unless compelled to do so by law or regulation, or business necessity. Nothing in this Section is intended to prevent Executive from disclosing the fact that he was employed by the Company and/or its Affiliates or from describing his employment duties.

10.2 Executive agrees that during the three-year period following the Date of Termination, upon request from the Company, he will reasonably cooperate with the Company and/or its Affiliates in the defense of any claims or actions that may be made by or against the Company and/or its Affiliates that affect his prior areas of responsibility, except if Executive’s reasonable interests are adverse to the Company and/or its Affiliates in such claim or action. To the extent travel is required to comply with the requirements of this Section 10.2, the Company shall, to the extent possible, provide Executive with notice at least 10 days prior to the date on which such travel would be required. The Company agrees to promptly reimburse Executive for all of his Company pre-approved reasonable travel and other direct expenses incurred, or to be reasonably incurred, to comply with his obligations under this Section 10.2.

Executive agrees to deliver to the Company on or before the Effective Date all originals and copies of Company materials and all other property of the Company and/or its Affiliates in Executive’s possession, custody or control.

The Company will only be responsible for the cost and expenses of moving personal property to one address in Houston or Sugarland, Texas.

15.1 The Parties acknowledge that this Agreement is the result of a compromise and shall never be construed as, or said by any of them to be, an admission by the other of any liability, wrongdoing, or responsibility. The Parties expressly disclaim any such liability, wrongdoing, fault, or responsibility.

15.2 This Agreement constitutes the entire agreement among the Parties, except to the extent that it expressly references provisions of the Amendment and the Employment Agreement that survive the termination thereof. This Agreement may be executed in identical counterparts, each of which shall constitute an original and both of which shall constitute one and the same agreement. Except as expressly provided herein, this Agreement supersedes the Amendment and the Employment Agreement and any severance benefit plan or program and any bonus program at the Company and/or its Affiliates.

15.3 In the event of a breach or threatened breach by Executive of any of the provisions of this Agreement, Executive hereby consents and agrees that the Company and/or its Affiliates shall be entitled to seek, in addition to other available remedies, a temporary or permanent injunction or other equitable relief against such breach or threatened breach from any court of competent jurisdiction, without the necessity of showing any actual damages or that money damages would not afford an adequate remedy, and without the necessity of posting any bond or other security. The aforementioned equitable relief shall be in addition to, not in lieu of, legal remedies, monetary damages or other available forms of relief.

15.4 The Parties warrant that no representations related to the subject matter of this Agreement have been made other than those contained in the written provisions of this Agreement, and that they do not rely on any representations not stated in this Agreement.

Each of the Company and Guarantor is relying on its own judgment and on the advice of its legal counsel and tax advisors and not upon any recommendation of Executive or his agents, counsel or other representatives. Likewise, Executive is relying on his own judgment and on the advice of his legal counsel and tax advisors, and not upon any recommendation of the Company, Guarantor or their respective directors, officers, employees, agents, counsel or other representatives. By voluntarily executing this Agreement, the Parties confirm their competence to understand and do hereby accept the terms of this Agreement as resolving fully all differences, disputes and claims that may exist within the scope of this Agreement.

15.7 This Agreement may not be modified or amended except by a writing signed by the Parties. No waiver of this Agreement or of any of the promises, obligations, terms, or conditions contained in it shall be valid unless it is in writing signed by the Party or Parties against whom the waiver is to be enforced. The waiver by any Party of a breach of any provision of this Agreement shall neither operate nor be construed as a waiver of any subsequent breach by any Party. Except as expressly provided for herein, the failure of any Party to take any action by reason of any breach will not deprive such Party of the right to take action at any time while such breach occurs.

15.8 If any part or any provision of this Agreement shall be finally determined to be invalid or unenforceable under applicable law by a court of competent jurisdiction, that part shall be ineffective to the extent of such invalidity or unenforceability only, without in any way affecting the remaining parts of said provision or the remaining provisions of the Agreement.

15.9 The Parties have cooperated in the preparation of this Agreement. Hence, the Agreement shall not be interpreted or construed against or in favor of any Party by virtue of the identity, interest, or affiliation of its preparer.

15.10 This Agreement is made and shall be enforced pursuant to the laws of the State of Texas, without regard to its law governing conflicts of law.

15.11 ANY LEGAL SUIT, ACTION OR PROCEEDING ARISING OUT OF OR BASED UPON THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY MAY BE INSTITUTED IN THE FEDERAL COURTS OF THE UNITED STATES OF AMERICA OR THE COURTS OF THE STATE OF TEXAS IN EACH CASE LOCATED IN THE CITY OF HOUSTON AND IN HARRIS COUNTY, AND EACH PARTY IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF SUCH COURTS IN ANY SUCH SUIT, ACTION OR PROCEEDING. SERVICE OF PROCESS, SUMMONS,

NOTICE OR OTHER DOCUMENT BY MAIL TO SUCH PARTY’S ADDRESS SET FORTH IN SECTION 15.15 SHALL BE EFFECTIVE SERVICE OF PROCESS FOR ANY SUIT, ACTION OR OTHER PROCEEDING BROUGHT IN ANY SUCH COURT. THE PARTIES IRREVOCABLY AND UNCONDITIONALLY WAIVE ANY OBJECTION TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR ANY PROCEEDING IN SUCH COURTS AND IRREVOCABLY WAIVE AND AGREE NOT TO PLEAD OR CLAIM IN ANY SUCH COURT THAT ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

15.12 EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND, THEREFORE, EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL ACTION ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY TO THIS AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT SEEK TO ENFORCE THE FOREGOING WAIVER IN THE EVENT OF A LEGAL ACTION, (B) SUCH PARTY HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) SUCH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (D) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 15.12.

With respect to any reimbursement of expenses of Executive or in-kind benefits, as specified under this Agreement, which constitutes deferred compensation subject to Section 409A of the Code, such reimbursement of expenses or paid expenses shall be subject to the following conditions: (1) the expenses eligible for reimbursement or payable in one taxable year shall not affect the expenses eligible for reimbursement or payment in any other taxable year; (2) the reimbursement or payment of an eligible expense shall be made no later than the end of the year after the year in which such expense was incurred or due; and (3) the right to reimbursement or payment shall not be subject to liquidation or exchange for another benefit. Notwithstanding the foregoing, Executive hereby acknowledges that none of the Company and/or its Affiliates guarantees or is otherwise responsible for the tax consequences to Executive with respect to this Agreement and actions contemplated hereby.
