agreement between Siris and any member of the Company Group with respect to the scope of such other services and the payment to be made to Siris for providing such other services. 

3. Fees. 
 a) The parties
acknowledge that, in the ordinary course, in consideration for Services provided by Siris on or before the date hereof, the Company would pay, or cause to be paid, to Siris (or its designee), at or promptly following the closing of the Transaction,
a consulting fee in an agreed-upon amount. That consulting fee has been waived.

c) In the event any member of the Company Group contemplates or consummates a significant transaction after the date hereof, in consideration
for Services provided by Siris in connection therewith, the Company will pay, or cause to be paid, to Siris (or its designee) a reasonable and customary consulting fee in an amount to be agreed upon by Siris and the board of directors of the Company
(or its designee) based on such relevant factors as they may choose to consider, including the nature of the Services to be provided by Siris, the complexity of the contemplated transaction, and the time and resources to be spent by Siris in
connection therewith; provided, however, that any such fee must be approved in accordance with Section 3.4(a) of the Amended and Restated Exempted Limited Partnership Agreement of Investments by the Requisite Partners (as defined
therein). 
 d) Any and all fees payable pursuant to this Section 3 shall be paid free and clear of any withholding
taxes and value added taxes. In the event that any such taxes apply, the Company will pay, or cause to be paid, an additional amount to Siris such that, after taking into account such taxes on such additional amount, Siris will receive an amount

day on which the Company is permitted and otherwise able to make such payment, or cause such payment to be made, and (ii) total or partial liquidation, dissolution or winding up of the Company. Any such payment deferred pursuant to this
Section 3(e) will bear interest at a rate of 1.5% per month (or, if less, the maximum amount permitted under applicable law), calculated based on the actual number of days elapsed from the date such payment was otherwise
due through the date such payment was made. 
 4. Term; Termination.

consummation of an initial public offering of the equity securities of any member of the Company Group or any of their respective successors and (ii) the consummation of a change of control of, or sale of all or substantially all of the assets
of, the Company Group or its successors, taken as a whole (the “Term”); provided, however, that Siris may cause this Agreement to terminate at any time upon ten business days’ prior written notice to the
Company. The date on which any termination under this Section 4(a) is effective is referred to herein as the “Termination Date.”

 b) Section 3(e) and Sections 4 through 16 of this Agreement shall
survive any termination of this Agreement with respect to matters occurring before, on or after the date of such termination. The occurrence of the Termination Date will not affect the obligations of the Company to pay, or cause to be paid, any
amounts accrued but not yet paid as of such date. 
 5.

each of the partners, stockholders, members, Affiliates, directors, officers, fiduciaries, managers, controlling Persons, employees, consultants, advisors, agents and representatives of each of the foregoing (collectively, the
“Indemnitees”) who is or was a party or is threatened to be made a party to or is otherwise involved in any respect in any and all actual or threatened actions, causes of action, suits, arbitrations, proceedings, investigations and
claims (in each case, whether civil, criminal, regulatory, self-regulatory, administrative or investigative) (collectively, “Claims”) free and harmless from any and all liabilities, losses, damages, judgments, fines, amounts paid in
settlement, fees, costs and expenses (including attorneys’ fees and other Out-of-Pocket Expenses) incurred by the Indemnitees or any of them before, on or after the
Original Agreement Date (collectively, the “Indemnified Liabilities”), as a result of, arising out of any Claim that itself arises out of, or in any way relating to this Agreement, an Indemnitee’s investment in or ownership of
any member of the Company Group, or any operations of or advice or services provided (or not provided) by Siris to or on behalf of or for the benefit of any or all of the Company Group or any of their respective Affiliates from time to time
(including, but not limited to, any indemnification obligations under this Agreement assumed or incurred by any Indemnitee on behalf of any member of the Company Group, any of their respective Affiliates or any of the respective partners,
stockholders, members, directors, officers, fiduciaries, managers, controlling Persons, employees, consultants, advisors, agents or representatives of the foregoing); provided, that the foregoing indemnification rights shall not be available
to an Indemnitee (i) to the extent that any such Indemnified Liabilities have been determined by a final and binding non-

  
 -4- 

 
appealable determination of a court of competent jurisdiction to have arisen on account of such Indemnitee’s fraud, gross negligence or willful misconduct or (ii) where such
indemnification is not permitted in accordance with applicable law. If and to the extent that the foregoing undertaking may be unavailable or unenforceable for any reason, each member of the Company Group shall, and the Company hereby agrees to
cause the other members of the Company Group to, make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities to the extent permissible under applicable law. 

c) Each Indemnitee will have the right, upon demand, to prompt payment, advancement or reimbursement by the Company Group in respect of any
Indemnified Liabilities for which it may be entitled to indemnification or contribution hereunder; provided that each Indemnitee shall repay any such paid, advanced or reimbursed amounts that such Indemnitee shall have been determined by a final and
binding non-appealable determination of a court of competent jurisdiction to be ineligible to receive in accordance with the proviso to the penultimate sentence of Section 5(b). 

d) The rights of any Indemnitee to indemnification hereunder will be in addition to any other rights any such Person may have under any other
agreement or instrument to which such Indemnitee is or becomes a party or is otherwise a beneficiary or under any applicable law. To the maximum extent permitted by law, none of the Indemnitees will in any event be liable to the Company Group or any
of their respective Affiliates (i) with respect to any act, alleged act, omission or alleged omission pursuant to this Agreement or (ii) for any amount that, together with all amounts paid by any of the Indemnitees hereunder, is in excess
of the fees received by Siris hereunder. 
 e) Each member of the Company Group hereby acknowledges that the Indemnitees may have certain
rights to indemnification, contribution, payment, advancement or reimbursement of expenses, or insurance provided by Siris and certain of its Affiliates (collectively, the “Fund Indemnitors”). Each member of the Company Group hereby
agrees (i) that it is the indemnitor of first resort with respect to matters that are the subject of indemnification, contribution or payment, reimbursement or advancement of expenses under this Section 5 (it being
agreed that the Company’s obligations to the Indemnitees are primary, the obligations of each member of the Company Group that is a direct or indirect parent entity of the Company are secondary, and any obligation of the Fund Indemnitors to
pay, advance or reimburse Indemnified Liabilities or to provide indemnification, contribution or insurance for the same Indemnified Liabilities are tertiary), (ii) that it shall be required to pay, advance or reimburse the full amount of Indemnified
Liabilities incurred by the Indemnitees and shall be liable for the full amount of all Indemnified Liabilities to the extent legally permitted and as required by this Agreement (or any agreement between any member of the Company Group and the
Indemnitee), without regard to any rights the Indemnitee may have against the Fund Indemnitors, and (iii) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for
contribution, subrogation or any other recovery of any kind in respect thereof. Each member of the Company Group further agrees that no payment, advancement or reimbursement by the Fund Indemnitors on behalf of an Indemnitee with respect to any
Claim for which the Indemnitee has sought indemnification or contribution from the Company will affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such payment, advancement or
reimbursement to all of the rights of recovery of an Indemnitee against each member of the Company Group. 

  
 -5- 

 f) Each member of the Company Group also agrees that, without the prior written consent of
Siris, it will not settle, compromise or consent to the entry of any judgment in any pending or threatened Claim to which an Indemnitee is an actual or potential party and in respect of which indemnification could be sought hereunder, unless
(i) such settlement, compromise or consent requires only the payment of money for which the Company Group is solely responsible and (ii) such settlement, compromise or consent includes an unconditional release of such Indemnitee from all
liability arising out of such Claim. 
  

	 	6.	 Disclaimer and Limitation of Liability; Opportunities; Disclosures. 

g) Disclaimer. Siris does not make any representation or warranty, express or implied, in respect of the Services or any other services
contemplated hereunder. 
 h) Freedom to Pursue Opportunities. In recognition that the Indemnitees may have, and may in the future
have or may consider acquiring, investments in entities with respect to which certain Indemnitees may serve as a manager, partner, advisor, director or in some other capacity, and in recognition that the Indemnitees have myriad duties to various
investors and direct and indirect partners or members, and in anticipation that the Company Group, on the one hand, and certain Indemnitees or one or more of their respective Affiliates, associated investment funds or portfolio companies, on the
other hand, may engage in the same or similar activities or lines of business and have an interest in the same areas of corporate opportunities, and in recognition of the benefits to be derived by the Company Group hereunder and in recognition of
the difficulties that may confront any advisor that desires and endeavors fully to satisfy such advisor’s duties in determining the full scope of such duties in any particular situation, the provisions of this
Section 6(b) are set forth to regulate, define and guide the conduct of certain affairs of the Company Group as they may involve the Indemnitees. Except as Siris (as to itself and the other Indemnitees) may otherwise agree
in writing: 
 i. Each of the Indemnitees shall have the right: (A) to directly or indirectly engage in any business (including, without
limitation, any business activities or lines of business that are the same as, similar to or otherwise competitive with those that have been, are being or may be pursued by the Company Group), (B) to directly or indirectly do business with any
actual or potential client, customer or supplier of the Company Group, (C) to take any other action that it believes in good faith is necessary or appropriate to fulfill any obligations as described in the first sentence of this
Section 6(b), and (D) not to present potential transactions, matters or business opportunities to the Company Group, and to pursue, directly or indirectly, any such opportunity for itself, and to direct any such
opportunity to another Person. 
 ii. The Indemnitees shall have no duty (contractual or otherwise existing at law or in equity) to
communicate or present any corporate opportunities to the Company Group or to refrain from any actions specified in Section 6(b)(i), and each member of the Company Group, on its own behalf and on behalf of its Affiliates,
hereby renounces and waives any right to require the Indemnitees to act in a manner inconsistent with the provisions of this Section 6(b). 

  
 -6- 

 iii. In no event will any of the Indemnitees be liable to any member of the Company Group or
any of its Affiliates, directly or indirectly, for any breach of any duty (contractual or otherwise existing at law or in equity) by reason of any activities or omissions of the types referred to in this Section 6(b) or any
such Person’s participation therein. 
 i) Limitation of Liability. In no event will any of the Indemnitees be liable to any
member of the Company Group or any of its Affiliates, directly or indirectly, for any indirect, punitive, special, incidental or consequential damages, including, without limitation, lost profits or savings, whether or not such damages are
foreseeable, or for any third party Claims (whether based in contract, tort or otherwise), relating to the Services to be provided hereunder. 

j) Disclosures. Any advice, opinions or workproduct provided by Siris may not be disclosed or referred to publicly or to any third party
(other than the Company Group’s legal, tax, financial or other advisors), except as required by law or with prior written consent of Siris. Any such advice, opinions or workproduct has been prepared for the Company Group and not for any other
party. Accordingly, to the extent any other party (including the Company Group’s legal, tax, financial or other advisors) has been furnished with such advice, opinions or workproduct, such other party may not rely on such information for any
reason whatsoever, and the Company agrees to so advise such other party. 
 7. Assignment. Except as provided below, none of the
parties hereto shall have the right to assign this Agreement without the prior written consent of the other parties. Notwithstanding the foregoing, (a) Siris may assign all or part of its rights and obligations hereunder to any of its
Affiliates who agree in writing to be bound by the terms of this Agreement and, in the event it so assigns all of such rights and obligations, Siris shall be released of all of its obligations hereunder, and (b) the provisions hereof for the
benefit of the Indemnitees shall continue to inure to the benefit of such Indemnitees and their respective heirs, successors and assigns. 

8. Amendments and Waivers. No amendment or waiver of any term, provision or condition of this Agreement shall be effective unless in
writing and executed by Siris, Investments and the Company; provided, that Siris may waive or defer any portion of any payment to which it is entitled pursuant to this Agreement and, unless otherwise directed by Siris, such waived portion
shall revert to the Company. No waiver or deferral on any one occasion shall extend to or effect or be construed as a waiver or deferral of any right or remedy on any future occasion. No course of dealing of any Person nor any delay or omission in
exercising any right or remedy shall constitute an amendment of this Agreement or a waiver of any right or remedy of any party hereto.

 Exhibit 10.8 

AMENDED AND RESTATED EMPLOYMENT AGREEMENT 

THIS AMENDED AND RESTATED EMPLOYMENT AGREEMENT (the “Agreement’) is made as of the 25 day of February, 2015 between
Mavenir Systems, Inc., a Delaware corporation (the “Company”), and Bahram Jalalizadeh, an individual resident of the State of Texas (“Executive”). 

1. Employment; Duties; Full Time Employment. The Company hereby employs Executive, and Executive hereby accepts
employment, as Executive Vice President of Global Sales and Business Development of the Company. In such capacity, Executive shall perform such executive duties and exercise such powers for the Company and its subsidiaries as the Chief Executive
Officer and President of the Company may assign to or vest in Executive from time to time and, as such, from and after the date hereof shall report directly to and shall be subject to the direction of the Company’s Chief Executive Officer and
President. Executive covenants and agrees that, at all times during Executive’s employment, Executive shall devote Executive’s full business time and efforts to Executive’s duties as an employee of the Company and that Executive will
not, directly or indirectly, engage or participate in any other business or professional activities during Executive’s employment, other than activities for non-profit organizations that do not interfere
or conflict with Executive’s obligations hereunder and such other activities approved by the Board of Directors of the Company from time to time. 

2. At Will Employment. The Company agrees to employ Executive, and Executive agrees to serve the Company, on an “at
will” basis, which means that either the Company or Executive may terminate Executive’s employment with the Company at any time and for any or no reason, as provided in and subject to Sections 7 and 8 below. 

3. Compensation. During Executive’s employment, the Company shall pay to Executive the following compensation: 

(a) Base Salary. The Company shall pay Executive a base salary (“Base
Salary”) at the rate of $25,000.00 per month (annualized to $300,000), less applicable withholding taxes, payable in accordance with the Company’s normal payroll practices. The Base Salary may be increased by
the Board of Directors, or a duly authorized committee thereof, in its sole discretion. In addition, the Board of Directors, or a duly authorized committee thereof, may decrease the Base Salary in the event that the Board or such committee
determines that financial exigencies require such decrease, provided that the compensation of all executives of the Company is also reduced at the same time in a substantially commensurate manner. Any increase or decrease in Base Salary (together
with the then existing Base Salary) shall serve as the “Base Salary” for future employment under this Agreement. 
 (b) Equity
Compensation. Executive may be granted stock options, stock appreciation rights, restricted stock units, restricted stock or other stock- or performance-based equity awards (each, an “Award’), as determined
from time to time in the discretion of the Company’s Board of Directors or a duly authorized committee thereof, under the Company’s Amended and Restated 2005 Stock Plan, Amended and Restated 2013 Equity Incentive Plan or

 
any other equity incentive plan that may be adopted by the Company’s Board of Directors (each, an “Equity Plan”). The terms of any such Award, including
the vesting schedule, if any, will be set forth in an award agreement (an “Award Agreement”) in the form determined by the Company’s Board of Directors or a duly authorized committee thereof. The vesting
schedule of any such Awards shall be subject to additional acceleration as described in Section 7 of this Agreement, unless otherwise set forth in the applicable Award Agreement. 

4. Other Compensation and Benefits. In addition to the compensation specified in Section 3, the Company shall provide
the following to Executive: 
 (a) Incentive Plan Participation. Executive shall be eligible to participate in the Company’s
sales incentive plan, sales compensation plan or any other such incentive plan (each, a “Sales Incentive Plan”) to the extent determined by the Company’s Board of Directors or a duly authorized committee
thereof; provided however, that any such participation and payments shall be subject in all respects to the terms of such Sales Incentive Plan and the meeting of performance metrics as determined by the Company’s Board of Directors or a
duly authorized committee thereof. The Company’s Board of Directors or a duly authorized committee thereof shall set the target payments (the “Target Variable Compensation”) to be earned by Executive under
a Sales Incentive Plan for each calendar year. Executive and the Company agree that for the year ending December 31, 2015, Executive’s Target Variable Compensation pursuant to the Sales Incentive Plan shall be 100% of Executive’s Base
Salary. 
 (b) Benefits. During Executive’s employment, Executive shall be entitled to 

(i) vacation in accordance with the Company’s vacation policy, to be taken in accordance with such policy, (ii) holidays and sick
leave as made generally available to employees of the Company, and (iii) subject to eligibility therefor, the right to participate in any profit sharing plan, retirement plan, 401(k) plan, group life insurance plan and/or other insurance plan
or medical expense plan or dental expense plan maintained by the Company for its senior executives generally and, if applicable, their family members.

last day of Executive’s taxable year following the taxable year in which the expense was incurred and the right to reimbursement hereunder may not be exchanged for any other benefit.

and any compensation earned under any Sales Incentive Plan through the date of termination, except and only to the extent that any such Sales Incentive Plan specifically provides otherwise; 

(ii) accelerated vesting with respect to all Awards under an Equity Plan held by Executive, such that all Awards under an Equity Plan that

termination, except and only to the extent that any Award Agreement specifically provides otherwise; 
 (iii) continuing severance pay at a
rate equal to 100% of Executive’s Base Salary, as then in effect (less applicable withholding taxes), for a period of six (6) months from the date of such termination, to be paid periodically in accordance with the Company’s normal

 (v) reimbursement of all expenses for which Executive is entitled to be reimbursed pursuant
to Section 5 above, but for which Executive has not yet been reimbursed; provided however, in no event shall reimbursement of an eligible expense hereunder be made later than the last day of Executive’s taxable year following the

termination, except and only to the extent that any such Sales Incentive Plan specifically provides otherwise; 
 (ii) accelerated vesting
with respect to all Awards under an Equity Plan held by Executive, such that all Awards shall vest in full effective as of the date of such termination, except and only to the extent that any Award Agreement specifically provides otherwise,

 (vi)
four (4) payments (each a “Sales Incentive Payment”), payable on the dates of the next four (4) scheduled payments under the Sales Incentive Plan after the date of Executive’s termination, with
each such payment to be in an amount equal to the greater of (a) twenty-five percent (25%) of the Target Variable Compensation for the applicable year in which Executive is terminated, or (b) the actual amount of the Sales Incentive
Payment that Executive would have been entitled to receive on such payment date under the Sales Incentive Plan if Executive were still employed by the Company, in each case payable in accordance with the Company’s normal payroll practices
(subject to Sections 7(c) and 7(d)): provided however, that Executive shall not receive an amount, in the aggregate, pursuant to the Sales Incentive Payments that exceeds the Target Variable Compensation for the applicable year in which
Executive is terminated and Executive shall cease to be entitled to any additional Sales Incentive Payments once Executive has been paid an aggregate amount equal to the Target Variable Compensation; and 

(vii) no other severance or benefits of any kind. 

(c) Section 409A. Notwithstanding anything to the contrary in this Agreement, no severance pay or benefits to be paid
or provided to Executive, if any, pursuant to this Agreement that, when considered together with any other severance payments or separation benefits, are considered deferred compensation under Section 409A of the Internal Revenue Code of 1986,
as amended (the “Code”), and the final regulations and any guidance promulgated thereunder (“Section 409A”) (together, the
“Deferred Payments”) will be paid or otherwise provided until Executive has a “separation from service” within the meaning of Section 409A. Similarly, no severance payable to Executive, if any,
pursuant to this Agreement that otherwise would be exempt from Section 409A pursuant to Treasury Regulation Section 1.409A-1(b)(9) will be payable until Executive has a “separation from
service” within the meaning of Section 409A. If Executive is a “specified employee” within the meaning of Section 409A at the time of Executive’s termination (other than due to death), then the Deferred Payments that
are payable within the first six (6) months following Executive’s separation from service will become payable on the first payroll date that occurs on or after the date six (6) months and one (1) day following the date of
Executive’s separation from service. All subsequent Deferred Payments, if any, will be payable in accordance with the payment schedule applicable to each payment or benefit. Notwithstanding anything herein to the contrary, if Executive dies
following Executive’s separation from service but prior to the six (6) month anniversary of the separation from service, then any payments delayed in accordance with this paragraph will be payable in a lump sum as soon as administratively
practicable after the date of Executive’s death and all other Deferred Payments will be payable in accordance with the payment schedule applicable to each 

  
 -5- 

 
payment or benefit. Each payment and benefit payable under this Agreement is intended to constitute a separate payment for purposes of
Section 1.409A-2(b)(2) of the Treasury Regulations. The foregoing provisions are intended to comply with the requirements of Section 409A so that none of the severance payments and benefits to be
provided hereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply. The Company and Executive agree to work together in good faith to consider amendments to this
Agreement and to take such reasonable actions which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to Executive under Section 409A. References in this Agreement to
termination of Executive’s employment shall mean termination of Executive’s employment with the Company and all entities required to be aggregated with the Company and treated as one employer under Section 414(b) or (c) of the
Code under circumstances that give rise to a “separation from service” within the meaning given to that term under Section 409A. 

(d) Conditions Precedent. Any severance payments (other than payment of Base Salary pursuant to Section 7), vesting and/or benefits
contemplated by Section 7 above are conditional on Executive (i) continuing to comply with all of the provisions of Section 9 below and the terms of the Confidentiality Agreement (as defined below), and (ii) signing and not
revoking a separation agreement and release of claims providing for a release of all claims relating to Executive’s employment and/or this Agreement against the Company or its successor, its subsidiaries and parent company and their respective
directors, officers and stockholders, excluding claims for payments and/or benefits the Company is required to pay to Executive that have not been made or delivered in accordance with terms of a written agreement between the Company and Executive or
as required by law, in a form satisfactory to the Company, its parent company or its successor (the “Release”); provided that such Release becomes effective and irrevocable no later than sixty
(60) days following the termination date or such earlier date required by the Release (such deadline, the “Release Deadline”). If the Release does not become effective by the Release Deadline, Executive
will forfeit any rights to severance or benefits under this Section 7 or elsewhere in this Agreement. Any severance payments or other benefits under this Agreement that would be considered Deferred Payments (as defined in Section 7(c))
will be paid on, or, in the case of installments, will not commence until, the sixtieth (60th) day following Executive’s separation from service, or, if later, such time as required by Section 7(c). Except as required by Section 7(c),
any installment payments that would have been made to Executive during the sixty (60) day period immediately following Executive’s separation from service but for the preceding sentence will be paid to Executive on the sixtieth (60th) day
following Executive’s separation from service and the remaining payments will be made as provided in this Agreement, unless subject to the 6-month payment delay described herein. Any severance payments
under this Agreement that would not be considered Deferred Payments will be paid on, or, in the case of installments, will not commence until, the first payroll date that occurs on or after the date the Release becomes effective and any installment
payments that would have been made to Executive during the period prior to the date the Release becomes effective following Executive’s separation from service but for the preceding sentence will be paid to Executive on the first payroll date
that occurs on or after the date the Release becomes effective.

acquisitions within the twelve (12)- month period ending with the most recent acquisition) beneficial ownership (within the meaning of Rule 13d-3 of the Exchange Act) of securities possessing more than fifty
percent (50%) of the total combined voting power of the Company’s securities (as measured in terms of the power to vote with respect to the election of Board members) outstanding immediately after the consummation of such transaction or series
of related transactions, whether such transaction involves a direct issuance from the Company or the acquisition of outstanding securities held by one or more of the Company’s existing stockholders; or 

(D) a change in the composition of the Board over a period of thirty-six

Section 409A and payable upon a Change of Control, the term “Change of Control” shall mean an event described in one or more of the foregoing provisions of this definition, but only if it also constitutes a “change of control
event” within the meaning of Treas. Reg. §1.409A-3(i)(5).

purposes of this Agreement, “Good Reason” shall mean the occurrence of any of the following without Executive’s consent: (A) a material reduction of Executive’s duties or responsibilities,
relative to Executive’s duties or responsibilities as in effect immediately prior to such reduction; provided, however, that any reduction in Executive’s duties or responsibilities resulting solely from and occurring concurrently
with the Company being acquired by and made a part of a larger entity (as, for example, when a chief financial officer becomes an employee of the acquiring corporation following an acquisition but is not the chief financial officer of the acquiring
corporation) shall not constitute Good Reason; (B) except as provided in Section 3(a), a material reduction in the Executive’s Base Salary as in effect immediately prior to such reduction; (C) except as provided in
Section 3, a material reduction by the Company in the kind or level of employee benefits, including compensation under a Sales Incentive Plan (as provided by the terms of such Sales Incentive Plan in effect at the time of such material
reduction), to which the Executive was entitled immediately prior to such reduction, with the result that Executive’s overall benefits package is materially reduced; or (D) the relocation of Executive to a facility or a location more than
fifty (50) miles from Executive’s then present location.

any time for Cause, and Executive may at any time voluntarily resign without Good Reason. Termination for Cause shall be effective on the date the Company gives notice to Executive of such termination in accordance with this Agreement unless

 -9- 

 (ii) Provision of Confidential Information. Prior to the execution of this Agreement
the Company has provided, and following the execution of this Agreement, the Company agrees to continue to provide, Executive with Confidential Information regarding the Company that enabled and will continue to enable Executive to optimize the
performance of Executive’s duties to the Company. 
 (c) Ventures. If, during Executive’s employment, Executive is engaged
in or associated with the planning or implementing of any project, program or venture involving the Company and any third parties, all rights in such project, program or venture shall belong to the Company (or the third party, to the extent provided
in any agreement between the Company and the third party). Except as formally approved by the Company, Executive shall not be entitled to any interest in such project, program or venture or to any commission, finder’s fee or other compensation
in connection therewith other than the salary or other compensation to be paid to Executive as provided in this Agreement. 
 (d) Non-Solicitation. 
 (i) Non-Solicitation of Employees.
During employment and for a period of twelve (12) months following the end of employment, Executive will not (directly or indirectly, on behalf of Executive or any third party) hire any employee, contractor or consultant of the Company or

(ii) Non-Solicitation of Clients and Prospective Clients. During employment and for a period of

project has been conducted in the last two years), and shall not solicit or attempt to take away any business of the Company that is either under way or about to begin at the termination of Executive’s employment. 

(B) Executive shall not interfere or compete in any way with any proposal efforts of the Company already in progress (that is,
a proposal sent to or being then currently developed for a specific client or clients, or contemplated to be submitted to a specific client or clients by the Company within twelve (12) months) at the end of employment. 

  
 -10- 

 (C) Executive shall not make use of any of Executive’s personal

the termination of Executive’s relationship with the Company for any reason, whether with or without Cause, at the option either of the Company or Executive, with or without notice, Executive will not, either directly or indirectly,
(i) serve as an advisor, agent, consultant, director, employee, officer, partner, proprietor or otherwise of, (ii) have any ownership interest in (except for passive ownership of one percent (1%) or less of any entity whose securities have

control of, any business in competition with the Company’s business as conducted by the Company during the course of Executive’s employment with the Company. The foregoing covenant shall cover Executive’s activities in every part of
the Territory. “Territory” shall mean (i) all counties in the State of Texas, (ii) all other states of the United States of America and (iii) all other countries of the world; provided

Agreement and the Confidentiality Agreement, including, but not limited to, Executive’s obligation neither to use, except for the benefit of the Company, or to disclose the Company’s Confidential Information and Executive’s obligation
not to compete contained in subsection 9(e)(i) above is necessary to protect the Company’s Confidential Information and to preserve the Company’s value and goodwill. Executive further acknowledges the time, geographic and scope limitations
of Executive’s obligations under subsection 9(e)(i) above are reasonable, especially in light of the Company’s desire to protect its Confidential Information, and that Executive will not be precluded from gainful employment if Executive is
obligated not to compete with the Company during the period and within the Territory as described above. 
 (iii) The covenants contained in
subsection 9(e)(i) above shall be construed as a series of separate covenants, one for each city, county and state of any geographic area in the Territory. Except for geographic coverage, each such separate covenant shall be deemed identical in
terms to the covenant contained in subsection 9(e)(i). If, in any judicial proceeding, a court refuses to enforce any of such separate covenants (or any part thereof), then such unenforceable covenant (or such part) shall be eliminated from this
Agreement to the extent necessary to permit the remaining separate covenants (or portions thereof) to be enforced. In the event the provisions of subsection 9(e)(i) are deemed to exceed the time, geographic or scope limitations permitted by
applicable law, then such provisions shall be reformed to the maximum time, geographic or scope limitations, as the case may be, then permitted by such law. 

  
 -11- 

 (f) Acknowledgements. Executive acknowledges that the
non-solicitation and non-competition covenants Executive is providing in this Agreement are reasonable and necessary to protect the legitimate interests of the Company.
Executive further acknowledges that Executive’s non-disclosure promises contained in this Agreement and the Confidentiality Agreement are in exchange for the Company’s promises contained in this
Agreement and the Confidentiality Agreement to provide Executive with confidential information and trade secrets of the Company. 
 (g)
Other Obligations Upon Termination. On termination of Executive’s employment, Executive shall: 
 (i) immediately (and with
contemporaneous effect) resign any directorships, offices or other positions that Executive may hold in the Company or any of its affiliates; 

(ii) immediately deliver to the Company all documents, books, materials, records, correspondence, papers and information (on whatever media
and wherever located) relating to the business or affairs of the Company or its business contacts, any keys and any other property of the Company, which is in Executive’s possession or under Executive’s control; 

(iii) irretrievably delete any information relating to the business of the Company stored on any magnetic or optical disk or memory and all
matter derived from such sources which is in Executive’s possession or under Executive’s control outside the premises of the Company; and 

(iv) provide the Company with a signed statement that Executive has complied fully with Executive’s obligations under this
Section 9(g). 
 (h) Notification of New Employer. In the event that Executive leaves the employ of the Company, Executive grants
consent to notification by the Company to Executive’s new employer about Executive’s rights and obligations under this Agreement and the Confidentiality Agreement. 

10. Tax. If any portion of the severance benefits, or any other payment under this Agreement, or under any other agreement
with, or plan of the Company, including but not limited to restricted stock, stock options, warrants and other long-term incentives (in the aggregate, “Total Payments”) would be subject to the excise tax imposed
by Section 4999 of the Code, as amended, or any similar tax that may hereafter be imposed (such excise tax together with any similar tax are hereinafter collectively referred to as the “Excise Tax”), then
Executive shall be entitled to receive from the Company an additional payment (the “Gross-up Payment’)  

  
 -12- 

 
(i.e., in addition to such other severance benefits, or any other payments under this Agreement) in an amount such that the net amount of Total Payments and
Gross-up Payment retained by the Executive, after the calculation and deduction of all Excise Tax on the Total Payments and all federal, state and local income tax, employment tax and Excise Tax on the Gross-up Payment, shall be equal to the Total Payments. Notwithstanding any other provision of this Section 10 to the contrary, to the extent permitted under Section 409A of the Code or any regulatory
guidance issued thereunder by the Internal Revenue Service, the term “Excise Tax”, as defined above in this Section 10, shall include any interest or penalties imposed with respect to such Excise Tax. Subject to Section 7(c), any
Gross-up Payment shall be made as soon as practicable after Executive remits the related taxes, but in all events the Gross-up Payment shall be made within thirty
(30) days after Executive remits the related taxes to the taxing authority. 
 11. Clawback of Incentive Compensation.
Executive acknowledges that to the extent required by applicable law or any written Company policy that may, in the discretion of the Board of Directors or a duly authorized committee thereof, be adopted to implement the requirements of such law
(including without limitation Section 304 of the Sarbanes Oxley Act of 2002 and Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010), compensation paid to Executive shall be subject to any required
clawback, forfeiture, recoupment or similar requirement. Executive agrees that the terms and conditions of this Agreement shall be deemed automatically amended as may be necessary from time to time to ensure compliance by Executive, the Company and
this Agreement with such policies or applicable law. No clawback of compensation under any policy adopted as contemplated in this Section 11 shall give rise to Executive’s right to resign for Good Reason. 

12. Miscellaneous. 

(a) Withholding Taxes. The Company may withhold from all salary, bonus or other benefits payable under this Agreement all federal,
state, city or other taxes as shall be required pursuant to any law or governmental regulation or ruling. 
 (b) Entire Agreement; Binding
Effect. This Agreement and the Confidentiality Agreement (together with any Equity Plan and any Award Agreement issued as contemplated by Section 3(b) above) set forth the entire understanding between the parties as to the subject matter of
this Agreement and supersede all prior agreements, commitments, representations, writings and discussions between them; and neither of the parties shall be bound by any obligations, conditions, warranties or representations with respect to the
subject matter of this Agreement, the Confidentiality Agreement, any Equity Plan or any Award Agreement except as expressly provided herein or therein or as duly set forth on or subsequent to the date hereof in a written instrument signed by the
proper and fully authorized representative of the party to be bound hereby. This Agreement is binding on Executive and on the Company and Executive’s and the Company’s successors and assigns (whether by assignment, by operation of law or
otherwise); provided that neither this Agreement nor any rights or obligations hereunder may be assigned by Executive or the Company without the prior written consent of the other party (except that the Company shall be entitled to assign this
Agreement in connection with a Change of Control). 

  
 -13- 

 (c) Absence of Conflict. Executive represents and warrants that Executive’s
employment by the Company as described herein will not conflict with and will not be constrained by any prior employment or consulting agreement or relationship. Executive further agrees that during Executive’s employment with the Company,
Executive will not improperly use or disclose any proprietary information or trade secrets of any former or concurrent employer or other person or entity and that Executive will not bring onto the premises of the Company any unpublished document or
proprietary information belonging to any such employer, person or entity unless consented to in writing by such employer, person or entity. 

(d) Arbitration. 
 (i)
General. In consideration of Executive’s service to the Company, its promise to arbitrate all employment related disputes and Executive’s receipt of the compensation and other benefits paid to Executive by the Company, at present
and in the future, Executive agrees that any and all controversies, claims, or disputes (with the sole exception of those disputes that may arise from the Confidentiality Agreement, which shall be resolved in accordance with the dispute resolution
procedures set forth therein) with anyone (including the Company and any employee, officer, director, stockholder or benefit plan of the Company in their capacity as such or otherwise) arising out of, relating to, or resulting from Executive’s
service to the Company under this Agreement or otherwise or the termination of Executive’s service with the Company, including any breach of this Agreement, shall be subject to binding arbitration under the Arbitration Rules set forth by the
American Arbitration Association for the resolution of employment disputes (the “Rules”) and pursuant to Texas law. Disputes which Executive agrees to arbitrate, and thereby agrees to waive any right to a trial
by jury, include any statutory claims under state or federal law. Executive further understands that this Agreement to arbitrate also applies to any disputes that the Company may have with Executive. 

(ii) Procedure. Any arbitration will be administered by the American Arbitration Association
(“AAA”) and a neutral arbitrator will be selected in a manner consistent with its National Rules for the Resolution of Employment Disputes. The arbitration proceedings will be conducted in Richardson, Texas, and
will allow for discovery according to the rules set forth in the National Rules for the Resolution of Employment Disputes. The arbitrator shall have the power to decide any motions brought by any party to the arbitration, including motions for
summary judgment and/or adjudication and motions to dismiss and demurrers, prior to any arbitration hearing. The arbitrator shall issue a written decision including findings of fact and conclusions of law on the merits of its award. The arbitrator
shall have the power to award any remedies, including attorneys’ fees and costs, available under applicable law. The Company will pay for any administrative or hearing fees charged by the arbitrator or AAA except that Executive shall pay the
first $125 of any filing and/or administration fees associated with any arbitration that Executive initiates. The arbitrator shall administer and conduct any arbitration in a manner consistent with the AAA’s National Rules for the Resolution of
Employment Disputes.

 (iii) Remedy. Arbitration shall be the sole, exclusive and final remedy for any
dispute (with the sole exception of those disputes that may arise from the Confidentiality Agreement and Section 9 of this Agreement) between Executive and the Company. Accordingly, except as otherwise provided herein, neither Executive nor the
Company will be permitted to pursue court action regarding claims that are subject to arbitration. Notwithstanding, the arbitrator will not have the authority to disregard or refuse to enforce any lawful Company policy, and the arbitrator shall not
order or require the Company to adopt a policy not otherwise required by law, which the Company has not adopted. 
 (iv) Availability of
Injunctive Relief. Any party may also petition the court for injunctive relief where either party alleges or claims a violation of this Agreement or the Confidentiality Agreement, including but not limited to a breach of the restrictive
covenants in Section 9 above. In the event that either party seeks injunctive relief, no bond shall be required and the prevailing party shall be entitled to recover reasonable costs and attorneys’ fees. 

(e) Voluntary Nature of Agreement; Legal Rights. Executive is executing this Agreement voluntarily and without any duress or undue
influence by the Company or anyone else. Executive acknowledges that Executive has had the opportunity to consult with an attorney regarding the provisions of this Agreement and has either obtained such advice of counsel or knowingly waived the
opportunity to seek such advice. Executive has carefully read this Agreement and has asked any questions needed for Executive to understand the terms, consequences and binding effect of this Agreement and fully understand it, including that
Executive is waiving Executive’s right to a jury trial. 
 (f) Waivers. No party shall be deemed to have waived any right, power
or privilege under this Agreement or any provisions hereof unless such waiver shall have been duly executed in writing and acknowledged by the party to be charged with such waiver. The failure of any party at any time to insist on performance of any
of the provisions of this Agreement shall in no way be construed to be a waiver of such provisions, nor in any way to affect the validity of this Agreement or any part hereof. No waiver of any breach of this Agreement shall be held to be a waiver of
any other subsequent breach. 
 (g) Reformation. If any sentence, paragraph or clause of this Agreement, or combination of the same,
is in violation of any applicable law or regulation, or is unenforceable or void for any reason, such sentence, paragraph, clause or combinations of same shall be modified to the extent necessary to accomplish the intention on such provision without
violating applicable law or regulation. Notwithstanding, the remainder of the Agreement shall remain binding upon the parties. 
 (h)
Notices. All notices, approvals, consents, requests or demands required or permitted to be given under this Agreement shall be in writing and shall be deemed sufficiently given on the earlier of (i) actual receipt, (ii) three
business days after being deposited in U.S. mail, registered or certified, postage prepaid, (iii) upon delivery, if delivered by hand (iv) one business day after transmission, if sent by facsimile (confirmation received) or (v) one
business day after the business day of deposit with a reputable overnight courier for next business day delivery, freight prepaid. Notice in each case shall be addressed to the party entitled to receive such notice at the following address (or other
