educational, philanthropic or charitable boards or committees; and (iii) serve on any other corporate board or committee as long as such board or committee is disclosed to the Company and does not cause a conflict of interest with

 (b) Bonus Compensation. Effective as of April 1, 2011, and as
reviewed from time to time by the Company, the Employee shall be eligible for a bonus targeted at $260,000.00, paid on a quarterly basis, based on the attainment of certain quarterly corporate and individual performance objectives agreed upon in

(c) Stock Options, Restricted Stock (“RS”), and Restricted Stock Units (“RSUs”). Upon approval

 3. Confidential Information and Restricted Activities. 

(a) Confidential Information. During the course of the Employee’s employment with the Company, the Company
agrees to provide the Employee with Confidential Information, as defined below, and the Employee may develop Confidential Information on behalf of the Company. The Employee agrees that Employee will not use or disclose to any Person (except as
required by applicable law or for the proper performance of the Employee’s regular duties and responsibilities for the Company) any Confidential Information obtained by the Employee incident to the Employee’s employment or any other
association with the Company or any of its Affiliates. The Employee understands that this restriction shall continue to apply after the Employee’s employment terminates, regardless of the reason for such termination. 

(b) Protection of Documents. All material documents, records, software and files, in any media of whatever kind and
description, relating to the business of the Company and its Affiliates, and any copies, in whole or in part, thereof (the “Documents”), whether or not prepared by the Employee shall be the sole and exclusive property of the Company. The
Employee agrees to safeguard all Documents and, at the time the Employee’s employment terminates or at such earlier time or times as the Board or its designee may specify, Employee agrees to surrender all Documents in Employee’s possession
or control to the Company.

 (c) Non-Competition. The Company agrees to provide Employee with
Confidential Information which, if disclosed, would assist in competition against the Company and that the Employee will also generate goodwill for the Company in the course of the Employee’s employment. Therefore, the Employee agrees that the
following restrictions on the Employee’s activities during and after the Employee’s employment are necessary to protect the goodwill, Confidential Information and other legitimate interests of the Company: 

(i) While the Employee is employed by the Company and for twelve (12) months thereafter, the Employee shall not,
directly or indirectly, whether as owner, partner, investor, consultant, agent, employee, co-venturer or otherwise (collectively, a “Competitive Role”), actively compete with the Company or any of its Affiliates or undertake any planning
for any business that is Competitive (as defined in the Company’s in the Company’s Employee Proprietary Invention Agreement (“EPIA”) with the Company or its Affiliates. 

(ii) The Employee agrees that during the twelve (12) months immediately following Employee’s resignation of
employment or during six (6) months following an involuntary termination of the Employee’s employment without Cause, the Employee will not, directly or through any other Person, (A) hire any employee of the Company or any of its
Affiliates or seek to persuade any employee of the Company or any of its Affiliates to discontinue employment, (B) solicit or encourage any customer of the Company or any of its Affiliates or independent contractor providing services to the
Company or any of its Affiliates to terminate or diminish its relationship with them or (C) seek to persuade any customer or active prospective customer of the Company or any of its Affiliates to conduct with anyone else any business or
activity that such customer or prospective customer conducts or could reasonably be expected to conduct with the Company or any of its Affiliates at that time. 
 (d) In signing this Agreement, the Employee gives the Company assurance that the Employee has carefully read and considered all the terms and conditions of this Agreement, including the restraints imposed
on the Employee under this Section 3. The Employee agrees without reservation that these restraints are necessary for the reasonable and proper protection of the Company and its Affiliates and that each and every one of the restraints is
reasonable in respect to subject matter, length of time and geographic area. The Employee further agrees that, were the Employee to breach any of the covenants contained in this Section 3, the damage to the Company and its Affiliates would be
irreparable. The Employee agrees that the Company, in addition to any other remedies available to it, shall be entitled to apply for injunctive relief in a court of appropriate jurisdiction. The Employee and the Company further agree that, in the
event that any provision of this Section 3 is determined by any court of competent jurisdiction to be unenforceable by reason of its being extended over too great a time, too large a geographic area or too great a range of activities, the court
may modify and enforce the covenant to the extent it believes to be reasonable under the circumstances. It is also agreed that each of the Company’s Affiliates shall have the right to enforce all of the Employee’s obligations to that
subsidiary under this Agreement, including without limitation pursuant to this Section 3. 
 4. Termination of
Employment. The Employee’s employment under this Agreement shall continue until terminated pursuant to this Section 4. 
 (a) The Company may terminate the Employee’s employment for Cause following at least fifteen (15) days advance written notice to the Employee setting forth in reasonable detail the nature of the
Cause. For purposes of this Agreement, “Cause” means any of the following: (i) the Employee’s continued substantial violations of Employee’s employment duties or willful disregard of commercially reasonable and lawful
directives from the Managing 

  
 - 3 -









 
Executive, after Employee has received a written demand for performance from the Managing Executive that sets forth the factual basis for the Company’s belief that Employee has not
substantially performed Employee’s duties or willfully disregarded directives from the Managing Executive; (ii) the Employee’s moral turpitude, dishonesty or gross misconduct in the performance of Employee’s duties or which has
materially and demonstrably injured the finances or future business of the Company or any of its Affiliates as a whole; (iii) the Employee’s material breach of this Agreement; or (iv) the Employee’s conviction of, or confession
or plea of no contest to, any felony or any other act of fraud, misappropriation, embezzlement, or the like involving the Company’s property; provided, however, that no such act or event described in clauses (i) and (iii) of this
paragraph (a) shall constitute Cause hereunder if the Employee has fully cured such act or event during the applicable fifteen (15) day notice period. 
 (b) This Agreement shall automatically terminate in the event of Employee’s death during employment. No severance pay or other separation benefits will be paid in the event of such termination due to
death except that Employee’s beneficiaries shall be entitled to receive any accrued Base Salary, any bonus compensation to the extent earned, any vested deferred compensation or Stock Options, RS, or RSU Grants (other than pension plan or
profit-sharing plan benefits which will be paid in accordance with the applicable plan), any benefits under any plans of the Company in which Employee is a participant to the full extent of Employee’s rights under such plans, and any
appropriate business expenses incurred by Employee in connection with his duties hereunder, all to the date of termination (collectively “Accrued Compensation”). In the event the Employee becomes disabled during employment and, as a
result, is unable to continue to perform substantially all of Employee’s duties and responsibilities under this Agreement for a consecutive period of twelve (12) weeks, the Company will continue to pay the Base Salary to Employee and
benefits in accordance with Section 2(d) above during such period. If the Employee is unable to return to work after twelve (12) consecutive weeks of disability, the Company may terminate the Employee’s employment, upon notice to the
Employee. No severance pay or other separation benefits will be paid in the event of such termination due to disability. If any question shall arise as to whether the Employee is disabled to the extent that the Employee’s duties and
responsibilities for the Company, the Employee shall, at the Company’s request, and at the Company’s expense, submit to a medical examination by a physician selected by the Company to whom the Employee’s guardian, if any, has no
reasonable objection to determine whether the Employee is so disabled and such determination shall for the purposes of this Agreement be conclusive of the issue. If such a question arises and the Employee fails to submit to the requested medical
examination, the Company’s determination of the issue shall be binding on the Employee. 
 (c) Either the
Company or Employee may terminate Employee’s employment “at will,” for any reason, at any time, without cause or notice. However, in the event of termination of the Employee’s employment by the Company other than for Cause, the
Employee shall be entitled to receive: (i) a lump sum cash severance amount equivalent to six (6) months of Employee’s then current annual base salary (the “Severance Payments”), less applicable deductions;
(ii) any earned but unpaid incentive compensation payments; and (iii) reimbursement of the health and dental care continuation premiums for Employee and Employee’s dependents incurred by Employee to effect continuation of health and
dental insurance coverage for Employee and Employee’s dependents on the same basis as active employees, for a period of twelve (12) months from the date of such termination, to the extent that Employee is eligible for and elects
continuation coverage under COBRA. Any obligation of the Company to provide the Employee

severance payments under this Section 4(c) is conditioned, however, upon the Employee signing and not revoking a release of claims in the form provided by the Company and reasonably
acceptable to Employee that becomes effective no later than seventy-four (74) days following the Employee’s termination date or such earlier date required by the release agreement (such deadline, the “Release Deadline”). If the
release does not become effective by the Release Deadline, the Employee will forfeit any rights to severance payments under this Section 4(c). In no event will severance payments or benefits be paid or provided until the release actually
becomes effective. In the event the termination occurs at a time during the calendar year where the release could become effective in the calendar year following the calendar year in which the Employee’s termination occurs, then any severance
payments or benefits under this Agreement that would be considered Deferred Compensation (as defined below) will be paid or provided on the first payroll date to occur during the calendar year following the calendar year in which such termination
occurs, or, if later, the later of (i) the Release Deadline, or (ii) the Deferred Compensation Delayed Payment Date (as defined in Section 7 below). 

(d) In the event of termination of the Employee’s employment by the Company for Cause or the Employee’s
voluntary resignation, the Company will pay the Employee any Base Salary earned but not paid through the date of termination, any earned but unpaid bonus, and pay for any vacation time accrued but not used to that date. The Company shall have no
obligation to the Employee for unearned bonus or severance payments. 
 (e) In the event that the Company,
without Employee’s express written consent, shall materially reduce the powers and duties of employment of Employee resulting in a material decrease in the responsibilities of Employee, materially reduce the pay of Employee, fail to provide
directors and officers liability insurance covering Employee during the term of his employment (which failure would be a material breach of this agreement) or require a material change in the geographic location of Employee’s primary work
facility or location, and due to such act or event Employee terminates his employment with the Company within thirty (30) days following the expiration of any Company cure period (discussed below) following the occurrence of one or more of such
acts or events, such termination by Employee shall be deemed to be a “Constructive Termination”; provided, however, that a relocation of less than fifty (50) miles from the Company’s corporate headquarters in Austin, Texas
will not be considered a material change in geographic location and thus a termination by Employee for this reason shall not be construed as a Constructive Termination; and provided further, that Employee may not resign for Constructive
Termination unless Employee first provides the Company with written notice of the acts or events constituting the grounds for “Constructive Termination” within ninety (90) days of the initial existence of the grounds for
“Constructive Termination” and a reasonable cure period of not less than thirty (30) days following the date of such notice, and such grounds for “Constructive Termination” have not been cured during such cure period.

 (f) Except for any right the Employee may have under the federal law known as “COBRA” to continue
participation in the Company’s group health and dental plans, and subject to Section 4(c) (iii) above, benefits shall terminate in accordance with the terms of the applicable benefit plans based on the date of termination of the
Employee’s employment, without regard to any continuation of base salary or other payment to the Employee following termination. 

  
 - 5 -









 (g) Provisions of this Agreement shall survive any termination if so
provided in this Agreement or if necessary to accomplish the purposes of other surviving provisions, including without limitation the Employee’s obligations under Section 3 of this Agreement, with the exception of Section 3(c)(i),
which obligations do not survive termination. The obligation of the Company to make payments to the Employee under this Section 4 is expressly conditioned upon the Employee’s continued full performance of the obligations under
Section 3 hereof that survive the termination of Employee’s employment. Upon termination by either the Employee or the Company, all rights, duties and obligations of the Employee and the Company to each other shall cease, except as
otherwise expressly provided in this Agreement. 
 5. Change of Control Benefits. “Change of Control” shall be
defined as a transaction or series of transactions where the shareholders of the Parent immediately preceding such transaction own, following such transaction, less than 50% of the voting securities of the Parent; provided however, that a firmly
underwritten public offering of the Common Stock shall not be deemed a Change of Control. In the event of termination of the Employee’s employment by the Company other than for Cause or in the event of Constructive Termination, upon or during
the twelve (12) month period after the effective date of a Change of Control, the Employee shall be entitled to (i) a lump sum cash severance amount equivalent to six (6) months of Employee’s then current annual base salary;
(ii) all of Employee’s remaining unvested Stock Options, RS, or RSU Grants from all of Employee’s then-outstanding grants shall immediately and fully vest as of the date of such termination, and (iii) the Employee shall receive
the consideration set forth in sections 4(c) hereof. 
 6. Limitation on Payments. In the event that the severance and
other benefits provided for in this Agreement or otherwise payable to the Employee (i) constitute “parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) and
(ii) but for this Section 6, would be subject to the excise tax imposed by Code Section 4999 (the “Excise Tax”), then the Employee’s severance benefits will be either: (a) delivered in full, or (b) delivered
as to such lesser extent which would result in no portion of such severance benefits being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the Excise Tax,
results in the receipt by the Employee on an after-tax basis, of the greatest amount of severance benefits, notwithstanding that all or some portion of such severance benefits may be taxable under Code Section 4999. If a reduction in the
severance and other benefits constituting “parachute payments” is necessary so that no portion of such severance benefits is subject to the Excise Tax, the reduction shall occur in the following order: (1) reduction of the cash
severance payments; (2) cancellation of accelerated vesting of the Employee’s equity awards; and (3) reduction of continued employee benefits. In the event that acceleration of vesting of the Employee’s equity awards is to be
reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant of the Employee’s equity awards. Unless the Company and the Employee otherwise agree in writing, any determination required under this
Section 6 will be made in writing by an independent firm selected by the Company with the consent of Employee, which consent shall not be unreasonably withheld, delayed or conditioned (the “Firm”), immediately prior to the change of
control, whose determination will be conclusive and binding upon the Employee and the Company for all purposes. For purposes of making the calculations required by this Section 6, the Firm may make reasonable assumptions and approximations
concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Code Sections 280G and 4999. 

  
 - 6 -









 
The Company and the Employee will furnish to the Firm such information and documents as the Firm may reasonably request in order to make a determination under this Section 6. The Company
will bear all costs the Firm may reasonably incur in connection with any calculations contemplated by this Section 6. 

7. Section 409A. The foregoing provisions are intended to comply with the requirements of Code Section 409A and the
final regulations and official guidance promulgated thereunder (“Section 409A”), so that none of the payments and benefits to be provided hereunder will be subject to the additional penalty tax imposed under Section 409A, and any
ambiguities herein will be interpreted to so comply. The Company agrees to work together with the Employee in good faith to consider any and all amendments to this Agreement and to take such reasonable actions which are necessary, appropriate or
desirable to avoid imposition of any additional tax, interest penalty or accelerated income recognition prior to actual payment to the Employee under Section 409A. Notwithstanding anything to the contrary in this Agreement, no severance
payments or severance benefits payable to the Employee upon termination of employment, if any, when considered together with any other severance payments or separation benefits that are considered deferred compensation under Section 409A
(“Deferred Compensation”) will be payable until the Employee has a “separation from service” within the meaning of Section 409A. Further, if at the time of the Employee’s termination of employment, the Employee is a
“specified employee” within the meaning of Section 409A, payment of such Deferred Compensation will be delayed to the extent necessary to avoid the imposition of the additional tax imposed under Section 409A, which generally
means that the Employee will receive payment on the first payroll date that occurs on or after the date that is six (6) months and one (1) day following the Employee’s termination of employment, or the Employee’s death, if
earlier (the “Deferred Compensation Delayed Payment Date”). 
 8. Indemnification and Insurance. The Company
and Employee will enter into an Indemnification Agreement for Employee’s Benefit as approved by the Company’s Board of Directors and will maintain Director and Officers liability insurance for Employee during his Employment and for a
reasonable time thereafter as permitted by the Company’s Director and Officer Insurance Policy. 
 9. Definitions.
For purposes of this Agreement, the following definitions apply: 
 “Affiliates” means all persons and
entities directly or indirectly controlling, controlled by or under common control with the Company, where control may be by management authority, equity interest or otherwise. 

“Confidential Information” means matters relating to the financial condition, results of operations, business,
properties, assets, liabilities or future prospects of the Company and its Affiliates. Confidential Information does not include information that enters the public domain, other than through the Employee’s breach of the Employee’s
obligations under this Agreement. 
 “Person” means an individual, a corporation, a limited liability
company, an association, a partnership, an estate, a trust or any other entity or organization, other than the Company or any of its Affiliates.

 10. Conflicting Agreements. The Employee hereby represents and warrants that the
Employee’s signing of this Agreement and the performance of the Employee’s obligations under it will not breach or be in conflict with any other agreement to which the Employee is a party or are bound and that the Employee is not now
subject to any covenants against competition or similar covenants or any court order that could affect the performance of the Employee’s obligations under this Agreement. 
 11. Withholding. All payments made by the Company under this Agreement shall be reduced by any tax or other amounts required to be withheld by the Company under applicable law. 

12. Assignment. Neither the Employee nor the Company may make any assignment of this Agreement or any interest in it, by operation
of law or otherwise, without the prior written consent of the other. This Agreement shall inure to the benefit of and be binding upon the Employee and the Company, and each of our respective successors, executors, administrators, heirs and permitted
assigns. 
 13. Severability. If any portion or provision of this Agreement shall to any extent be declared illegal or
unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or the application of such portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable, shall not be affected
thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent permitted by law. 
 14. Miscellaneous. This Agreement and the EPIA, set forth the entire agreement between the Employee and the Company and replaces all prior and contemporaneous communications, agreements and
understandings, written or oral, with respect to the terms and conditions of the Employee’s employment. In the event of a conflict between the EPIA and this Agreement, the terms in this EPIA shall prevail except with respect to section 3(c)(ii)
which shall prevail over Section 5 of the EPIA. This Agreement may not be modified or amended, and no breach shall be deemed to be waived, unless agreed to in writing by the Employee and an expressly authorized representative of the
Board. The headings and captions in this Agreement are for convenience only and in no way define or describe the scope or content of any provision of this Agreement. This Agreement may be executed in two or more counterparts, each of which shall be
an original and all of which together shall constitute one and the same instrument. 
 15. Governing Law. This Agreement
shall be governed and construed in accordance with the laws of the State of Texas without regard to the conflict of laws principles thereof. 
 16. Notices. Any notices provided for in this Agreement shall be in writing and shall be effective when delivered in person or deposited in the United States mail, postage prepaid, and addressed to
the Company at its principal place of business, attention of the General Counsel or in the case of the Employee, at the Employee’s last known address on the books of the Company (or to such other address as either party may specify by notice to
the other actually received).
