9.Advice of Counsel, Consideration and Revocation Periods, Other Information. The Company advises Employee to consult with an attorney prior to signing this Agreement. Employee has 21 days to consider whether to sign this Agreement from the date Employee receives this Agreement and any attached information (the “Consideration Period”), which Employee can waive by signing and returning this Agreement to Company’s Vice President – Human Resources (“HR”) within the Consideration Period, but not before the Separation Date. If Employee signs and returns this Agreement before the end of the Consideration Period, it is because Employee freely chose to do so after carefully considering its terms. Additionally, Employee shall have seven days from the date the Employee signs and returns to the Company this Agreement (the “Revocation Period”) to revoke this Agreement by delivering a written notice of revocation to the Company’s Vice President – HR either by email or by certified or registered mail to 2277 Plaza Drive, Suite 500, Sugar Land, Texas 77479. If the Revocation Period expires on a weekend or holiday, Employee will have until the end of the next business day to revoke. This Agreement will become effective on the day after the end of the Revocation Period, provided Employee does not revoke this Agreement (the “Effective Date”). Employee and the Company agree that any changes proposed and/or made by either party to the Agreement, whether material or immaterial, do not restart the running of the Consideration

Period or the Revocation Period.

10.Non-Solicitation. In order to protect Released Parties’ confidential information and key relationships, Employee agrees that for a period of one year following the Effective Date, Employee will not directly or indirectly, in any capacity, and will not induce, encourage, or assist any other individual or entity, directly or indirectly, in any capacity, to or from: (a) hiring or engaging in any capacity any individual who is or was within the last twelve months an employee of any Released Parties of whom Employee gained knowledge through his employment, or solicit or seek to persuade any such individual to discontinue their employment with the Released Parties; (b) solicit or encourage any customer of or contractor providing any services to any Released Parties, with whom Employee had material contact or about whom he has had access to confidential information during the last two years of his employment, to terminate or diminish its relationship with the Released Parties; or (c) seek to persuade any current, former (within the last twelve months) or prospective customer of the Released Parties to conduct with anyone else any business or activity that such customer or prospective customer conducts or could conduct with any Released Parties; or (d) attempt to divert, divert, or otherwise usurp any actual or potential business opportunity or transaction about which Employee gained knowledge through his employment with the Company or its affiliates. For purposes of this Section 10, “in any capacity” includes, but is not limited to, as an employee, independent contractor, volunteer, or owner.1 Nothing herein is intended or to be construed as a prohibition against general advertising such as “help wanted” ads that are not targeted at the Released Parties’ employees.

11.Special Remedies. Each of Employee’s obligations under Section 10 of this Agreement shall be considered a separate and severable obligation. If a court or arbitrator determines that a restriction in this Agreement cannot be enforced as written due to an overbroad limitation (such as time, geography, or scope of activity), the parties agree that the court or arbitrator shall reform or modify the restrictions or enforce the restrictions to such lesser extent as is allowed by law. If, despite the foregoing, any provision in Section 10 is determined to be void or unenforceable, in whole or in part, then the other provisions of this Agreement will remain in full force and effect. The Parties agree that the Company will suffer irreparable harm, in addition to any damages that can be quantified, by a breach of this Agreement by Employee. Accordingly, in the event of such a breach or a threatened breach, the Released Parties will be entitled to all remedies that may be awarded by a court of competent jurisdiction or arbitrator.

12.Applicable Law and General Provisions. This Agreement shall be interpreted under the law of the state in which Employee worked for the Company. Any unresolved dispute arising out of this Agreement and the general release contained herein shall be litigated

1 If Oklahoma law is deemed to apply, then the following applies to Employee: (i) Sections 10 (b) and (c) are rewritten and replaced with the following: “solicit the established customers of the Company for the purpose of doing any business that would compete with the Company’s business”; and (ii) Section 10 (d) shall not apply.

exclusively in any court of competent jurisdiction sitting in Houston, Texas, provided that the Released Parties may elect to pursue, without having to post any bond in connection therewith, a court action to seek injunctive relief in any court of competent jurisdiction to enforce any of its rights hereunder, including, without limitation, to terminate the violation of any of its proprietary rights, including but not limited to trade secrets, copyrights or trademarks as well as the restrictions in Section 10. Each party shall pay its own costs and fees in connection with any dispute or litigation hereunder.

13.General Provisions. Employee is not relying on any other agreements or oral representations not addressed in this Agreement. This Agreement sets forth the entire agreement between the parties, and any prior agreements between or directly involving Employee and the Company are superseded by this Agreement, except Employee’s obligations under previously signed agreements or applicable policies related to business ideas, insider trading, confidentiality and unfair competition remain intact. The provisions of this Agreement are severable, and if any part of this Agreement except the release of claims is found by a court of law to be unenforceable, the remainder of this Agreement will continue to be valid and effective, and such provision shall be narrowed as minimally as necessary to make it enforceable and shall then be enforceable in its narrowed form. The headings in this Agreement are provided for reference only and shall not affect the substance of this Agreement. This Agreement may be executed in two or more counterparts, each of which shall be in an original, but all of which shall constitute one and the same instrument, and facsimile or PDF pages containing the parties’ signatures shall have the same effect as the originals.

14.Protected Rights. By signing this letter agreement, Employee is not waiving his right to file a charge with, or participate in an investigation conducted by, any governmental agency, including, without limitation, the United States Equal Employment Opportunity Commission (EEOC). Nevertheless, as set forth in paragraph 3 above, Employee acknowledges that he cannot benefit monetarily or obtain damages or equitable relief of any kind from or through any such charge or any action commenced by a government agency or third party with respect to claims waived in paragraph 3.    

In exchange for the promises contained in this Agreement, the Company promises to provide the benefits set forth in this Agreement.
