5 payments in the nature of severance or termination payments except as specifically provided herein. Items 5.1(a)(i) through 5.1(a)(iv) are referred to herein collectively as the “Accrued Amounts.” (b) For purposes of this Agreement, “Cause” shall mean: (i) The Executive’s willful or malicious acts or omissions that causes direct harm or damage to the Company, another employee, or a third party entity or individual, in the Executive’s capacity as an employee of the Company; (ii) the Executive's willful failure to perform the Executive's duties (other than any such failure resulting from incapacity due to physical or mental illness); (iii) the Executive's willful failure to comply with any valid and legal directive of the Board or the person to whom Executive reports; (iv) the Executive's engagement in dishonesty, illegal conduct, or misconduct, which is, in each case, injurious to the Company or its affiliates, as reasonably determined by the Board; (v) the Executive's embezzlement, misappropriation, or fraud, whether or not related to the Executive's employment with the Company; (vi) the Executive's conviction of or plea of guilty or nolo contendere to a crime that constitutes a felony (or state law equivalent) or a crime that constitutes a misdemeanor involving moral turpitude; (vii) the Executive's material violation of the Company's written policies or codes of conduct, including written policies related to discrimination, harassment, performance of illegal or unethical activities, and ethical misconduct; (viii) the Executive's material breach of any material obligation under this Agreement or any other written agreement between the Executive and the Company; or (ix) the Executive's engagement in conduct that brings or is reasonably likely to bring the Company negative publicity or into public disgrace, embarrassment, or disrepute. For purposes of this provision, none of the Executive's acts or failures to act shall be considered “willful” unless the Executive acts, or fails to act, in bad faith or without reasonable belief that the action or failure to act was in the best interests of the Company. The Executive's actions, or failures to act, based upon authority given pursuant to a resolution duly adopted by the Board or upon the advice of counsel for the Company shall be conclusively presumed to be in good faith and in the best interests of the Company.

6 Except for a failure, breach, or refusal which, by its nature, cannot reasonably be expected to be cured, the Executive shall have 10 business days from the delivery of written notice by the Company within which to cure any acts constituting Cause. (c) For purposes of this Agreement, “Good Reason” shall mean the occurrence of any of the following, in each case during the Employment Term without the Executive's prior written consent: (i) a material reduction in the Executive's Base Salary other than a general reduction in Base Salary that affects all similarly situated executives in substantially the same proportions; (ii) a relocation of the Executive's principal place of employment by more than 100 miles (other than as described in Section 5.1(c)(iii)); (iii) if, by the date which is 330 calendar days following the commencement of the Executive’s employment, the Company has failed to offer the Executive the opportunity to work (as the Executive’s principal place of employment) at a Company office located in the metropolitan areas of Dallas-Fort Worth, Houston, or any similar major metropolitan area within Texas; or (iv) any material breach by the Company of any material provision of this Agreement. To terminate the Executive's employment for Good Reason, the Executive must provide written notice to the Company of the existence of the circumstances providing grounds for termination for Good Reason within 30 days of the initial existence of such grounds and the Company must have at least 30 days from the date on which such notice is provided to cure such circumstances. If the Executive does not terminate the Executive's employment for Good Reason within 60 days after the first occurrence of the applicable grounds, then the Executive will be deemed to have waived the Executive's right to terminate for Good Reason with respect to such grounds. 5.2 Expiration of Term, Termination by Company Without Cause or Termination by Executive for Good Reason. The Employment Term and the Executive's employment hereunder may be terminated by the Executive for Good Reason or by the Company without Cause or on account of the Company’s failure to renew the Agreement in accordance with Section 1.

The Executive shall be eligible to receive such reimbursement until the earliest of: (i) the 12-month anniversary of the date of the Executive's termination; (ii) the date the Executive is no longer eligible to receive COBRA continuation coverage; or (iii) the date on which the Executive becomes eligible to receive health insurance coverage from another employer or other source. Notwithstanding the foregoing, if the Company's making payments under this Section 5.2(c) would violate the nondiscrimination rules applicable to non-grandfathered, insured group health plans under the Affordable Care Act (the “ACA”), or result in the imposition of penalties under the ACA and the related regulations and guidance promulgated thereunder, the parties agree to reform this Section 5.2(c) in a manner as is necessary to comply with the ACA. 5.3 Death or Disability. (a) The Executive's employment hereunder shall terminate automatically upon the Executive's death during the Employment Term, and the Company may terminate the Executive's employment on account of the Executive's Disability.

For purposes of Section 409A, each installment payment provided under this Agreement shall be treated as a separate payment and any right to a series of installment payments under this Agreement shall be treated as a right to a series of separate payments. Any payments to be made under this Agreement upon a termination of employment shall only be made upon a “separation from service” under Section 409A. Notwithstanding any provision of this Agreement to the contrary, in no event shall the timing of Executive’s execution of a release, directly or indirectly, result in Executive designating the calendar year of payment of any deferred compensation subject to Section 409A, and if a payment subject to Section 409A is subject to execution of a release and could be made in more than one taxable year, payment of such an amount shall be made in the later taxable year.

10 15.2 Specified Employees.

The aggregate of any payments that would otherwise have been paid before the Specified Employee Payment Date shall be paid to the Executive in a lump sum on the Specified Employee Payment Date and thereafter, any remaining payments shall be paid without delay in accordance with their original schedule. 15.3 Reimbursements. To the extent required by Section 409A, each reimbursement or in-kind benefit provided under this Agreement shall be provided in accordance with the following, subject to proof thereof: (a) the amount of expenses eligible for reimbursement, or in-kind benefits provided, during each calendar year cannot affect the expenses eligible for reimbursement, or in- kind benefits to be provided, in any other calendar year; (b) any reimbursement of an eligible expense shall be paid to the Executive on or before the last day of the calendar year following the calendar year in which the expense was incurred; and (c) any right to reimbursements or in-kind benefits under this Agreement shall not be subject to liquidation or exchange for another benefit. 16.
