 (ii) an amount equal to your Base Salary (not taking into account any reduction in your Base Salary that
constitutes Good Reason for your termination) for the calendar year in which the Date of Termination occurs, to be paid within sixty (60) days following the Date of Termination or, if the Company elects, such amount to be paid in eighteen
(18) equal installments during the eighteen (18) month period following the Date of Termination, provided that any amounts payable under this subsection that are not exempt from Section 409A of the Internal Revenue Code of 1986, as

sixty (60) days following the Date of Termination. The value of the foregoing benefits shall be determined individually rather than in the aggregate, and shall be compared after subtracting applicable income and employment taxes. 

8.3. Termination by the Company for Reason Other Than Death, Disability or Cause or by Executive for Good Reason in connection with a Change
in Control. If (a) prior to and in connection with a Change in Control or (b) within two (2) years after the occurrence of a Change in Control, (i) the Company terminates your employment for a reason other than for death,

you were entitled (through insurance, direct reimbursement, or otherwise) immediately before the Date of Termination for eighteen (18) months after the Date of Termination, to be paid within sixty (60) days following the Date of
Termination. The value of the foregoing benefits shall be determined individually rather than in the aggregate, and shall be compared after subtracting applicable income and employment taxes. 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. 
 8.4.
Release. As a condition to receiving the payments provided in Section 8.2 or 8.3 (other than the Accrued Rights) (the “Severance Payments”), Executive (or, as applicable, Executive’s estate) must timely
execute and not revoke a full release and waiver of all claims against the Company and its affiliates substantially in the form attached hereto as Exhibit A and such release becomes effective within sixty (60) days of the Date of
Termination (such sixty (60)-day period, the “Release Executive Period”). To the extent that the Release Executive Period begins in one taxable year and ends in another taxable year,
the Severance Payments shall not be made until the second taxable year. 
 8.5. 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 Code. Amounts other than the Accrued Rights paid pursuant to this Section 8 shall be deemed severance pay and in lieu
of any further salary for periods subsequent to the Date of Termination. 
 8.6. 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 8.3 and the acceleration of vesting of equity awards under Company equity incentive plans) would
constitute a “Parachute Payment” (as defined in Section 280G(b)(2) of the 

  
 7 













 
Code), the total amounts received by you from the Company which constitute Parachute Payments shall be reduced by the minimum amount necessary so that no portion of such amounts received by you
shall be subject to the excise tax imposed by Section 4999 of the Code if and only if 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. The determination as to whether and to what extent payments you have the right to receive from the Company are required to be reduced in accordance with the preceding
sentence shall be made at the Company’s expense by a legal, accounting or consulting firm expert in such matters as appointed by the Company (the “Outside Firm”), taking into account the value of any reasonable
compensation for services to be rendered by you before or after the change in control, including under any agreement not to render services to competitors pursuant to any non-competition provisions that may
apply to you to the extent permitted by Section 280G of the Code and the Company shall cooperate in the valuation of any such services, including any non-competition provisions. In the event of any
underpayment or overpayment under this Agreement, as determined by the Outside Firm, the amount of such underpayment or overpayment shall immediately be paid to you or refunded to the Company, as the case may be, with interest at the applicable
federal rate provided for in Section 7872(f)(2) of the Code. The payment reduction contemplated by this Section 8.6 shall be made by reducing, first, payments or benefits to be paid in cash hereunder in the order in
which such payment would be paid or provided (beginning with such payment that would be made last in time and continuing, to the extent necessary, through to such payment that would be made first in time) and, then, reducing any payment to be
provided in-kind hereunder in a similar order.

provisions of this Agreement regarding the disclosure, ownership and use of the Confidential Information and Goodwill;

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 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. If you should die before all amounts that would still be payable to you hereunder if you had continued to live are paid, all such unpaid amounts, unless otherwise provided herein, shall he paid
in accordance with the terms of this Agreement to your devisee, legatee, or other designee or, if there be no such designee, to your estate. 

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. To the extent that the payment provided for herein results in compensation income to you for federal or state income tax purposes, you shall pay to the Company at the time of such event such amount of money as the Company may require to
meet its withholding obligation under applicable tax laws or regulations, if any, and, if you fail to do so, the Company is authorized to withhold from any cash remuneration then or thereafter payable to you, any tax required to be withheld by
reason of such resulting compensation income. If you make the election authorized by Section 83(b) of the Code, you shall submit to the Company a copy of the statement filed to make such election.

 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. All notices to the Company shall be directed to the attention of the Chief Executive Officer of the Company with a copy to
the Corporate Secretary of the Company. 
 19. MISCELLANEOUS. No provision of this Agreement may be modified, waived or discharged
except in writing specifically referring to such provision and signed by you and such officer of the Company as may be specifically designated by the Board. 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 be distinct, separate and cumulative and may be exercised from time to time as often as occasion may arise or as may be deemed expedient. 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. Other than as provided in Section 12(i), 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.

 20. VALIDITY. The invalidity or unenforceability of any provisions of this Agreement
shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect. 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. 

21. COUNTERPARTS. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original but all of
which together will constitute one and the same instrument.
