Amended and Restated Executive Employment Agreement (Pardeep Kohli)

 Exhibit 10.18 
 AMENDED AND RESTATED EMPLOYMENT AGREEMENT 
 THIS
AMENDED AND RESTATED EMPLOYMENT AGREEMENT (the “Agreement”) is made as of the 18th day of December, 2012 between Mavenir Systems, Inc., a Delaware corporation (the “Company”), and Pardeep Kohli, 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 President and Chief Executive Officer of the Company. In such capacity, Executive shall perform such executive duties and exercise such powers for the Company and its subsidiaries as the Board
of Directors 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 Board of Directors. Executive shall be
nominated to serve on the Board of Directors during his employment by the Company. 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 $31,666.67
per month (annualized to $380,000), 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 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 management incentive plan,
executive bonus plan or any other such incentive plan (each, a “Performance 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 Performance Incentive Plan and the meeting of performance metrics as determined by the Company’s Board of Directors or a duly authorized
committee thereof. 
 (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. 
 (c) Directors and Officers Insurance. Executive shall be covered by the
Company’s Directors and Officers Insurance to the extent that the Company currently has or in the future obtains such insurance, for so long as Executive remains an executive officer or director of the Company. 

5. Business Expenses. The Company shall reimburse Executive for all reasonable and necessary business and travel expenses incurred
by Executive in the performance of Executive’s duties under this Agreement. The determination of “reasonable and necessary” shall be made in the sole discretion of the Board. Such expenses shall be reimbursed in accordance with the
Company’s business expense guidelines, limits and procedures and upon presentation of proper expense vouchers or receipts; 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 taxable year in which the expense was incurred and the right to reimbursement hereunder may not be exchanged for any other benefit.

 6. Termination on Death or Disability. Executive’s employment will terminate
automatically upon Executive’s death or, upon thirty (30) days prior written notice from the Company, in the event of Disability. For purposes of this Section 6, “Disability” means that Executive, at the time
notice is given, has been unable to substantially perform Executive’s duties under this Agreement for not less than sixty (60) work days within a six (6) consecutive month period as a result of Executive’s incapacity due to a
physical or mental condition and, if reasonable accommodation is required by law, after reasonable accommodation. Upon any termination for death or Disability, Executive shall be entitled to receive (i) Executive’s Base Salary through the

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

each case at any time; provided, that if Executive is terminated by the Company involuntarily without Cause or Executive resigns with Good Reason upon or after a Change of Control, then Executive shall be entitled to receive: 

(i) the Base Salary through the date of termination and any compensation earned and unpaid under a Performance Incentive Plan through
the date of termination, except and only to the extent that any such Performance 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 and provided, that if a particular Award Agreement has a definition of “Change of Control” or “Change in Control” that differs from the definition of
“Change of Control” set forth in this Agreement, such other definition shall apply solely with respect to acceleration of vesting of such Award pursuant to this Section 7(b)(ii); 

(iii) continuing severance pay at a rate equal to 100% of Executive’s Base Salary, as then in effect (less applicable withholding

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
taxable year in which the expense was incurred and the right to reimbursement hereunder may not be exchanged for any other benefit; and 
 (vi) 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 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. 
 (e) Definitions. 

(i) Cause. For purposes of this Agreement, “Cause” shall mean: (A) Executive’s continued
failure to substantially perform the principal duties and obligations of Executive’s position with the Company (other than any such failure resulting from incapacity due to physical or mental illness), which failure is not remedied within ten

failure to act shall be considered “willful” unless done or omitted to be done in bad faith and without reasonable belief that the act or omission was in or not opposed to the best interests of the Company. The Board of Directors
(excluding Executive if Executive is at such time a member of the Board) shall make all determinations relating to termination, including without limitation any determination regarding Cause, pursuant to Sections 7(e)(i) and (iii).

ownership or control of the Company effected through any of the following transactions:

controlled by or is under common control with, the Company) of 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 outstanding securities (as measured in terms of the power to vote with respect to the election of Board members); 
 (B) the closing of a sale, transfer or other disposition of all or substantially all of the Company’s assets; 

(C) the closing of any transaction or series of related transactions pursuant to which any person or any group of
persons comprising a “group” within the meaning of Rule 13d-5(b)(1) of the Exchange Act (other than the Company or a person that, prior to such transaction or series of related transactions, directly or indirectly controls, is controlled
by or is under common control with, the Company) acquires directly or indirectly (whether as a result of a single acquisition or by reason of one or more 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 

  
 - 7 -

 
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 (36) consecutive months or less such that
a majority of the Board members ceases by reason of one or more contested elections for Board membership to be comprised of individuals who either (x) have been Board members continuously since the beginning of such period or (y) have been
elected or nominated for election as Board members during such period by at least a majority of the Board members described in clause (x) who were still in office at the time the Board approved such election or nomination. 

Notwithstanding the foregoing, solely with respect to any Award that is subject to 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). 
 (iii) Good Reason. For 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; (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), a material reduction by
the Company in the kind or level of employee benefits, including bonuses, 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. 
 (f) Amendment to Option Agreements. In the event that Executive is terminated without Cause or resigns for Good Reason, whether prior to or following a Change of Control, at the Executive’s
request, the Company will execute an amendment (the “Option Amendment”) to each option to purchase capital stock of the Company held by Executive on the date of such termination (collectively, the
“Stock Options”) that will extend the period that Executive has to exercise each such stock option to the date that is one year following the earliest to occur of (i) the consummation of a Change of Control;
(ii) the consummation of an initial public offering of the Company’s equity securities under the Securities Act of 1933, as amended (an “IPO”); or (iii) in the event that an IPO or a Change of Control has
been consummated prior to the date of such termination, the date of such termination without Cause or resignation for Good Reason. The Option Amendment will also provide that, notwithstanding the foregoing, in the event that during such one-year
period Executive is unable to sell any securities issuable upon exercise of the Stock Options because of lock-up, market stand-off or similar restrictions on selling such securities that are applicable to Executive, or Executive refrains from
selling such securities at the request of an underwriter of the Company, such one-year period shall be extended for a 

  
 - 8 -

 
period of time equal to the period the Executive is unable to sell such securities because of lock-up, market stand-off or similar restrictions or Executive refrains from selling such securities
at the request of an underwriter of the Company. The Option Amendment will be in a form reasonably satisfactory to the Company and Executive. In no event shall any such extension exceed the original term of any such Stock Option, unless at the time
of such Option Amendment the exercise price of the applicable Stock Options is equal to or exceeds the fair market value of the underlying common stock of the Company, and such Option Amendment otherwise complies with the requirement of the
applicable Section 409A regulations. 
 8. Involuntary Termination for Cause; Resignation without Good Reason.

 (a) Effectiveness. Notwithstanding any other provision of this Agreement, the Company may terminate Executive’s
employment at 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 otherwise agreed by the parties. Resignation by Executive without Good Reason shall be effective on the date Executive gives notice to the Company of such resignation in accordance with this Agreement unless otherwise agreed by the parties.

 (b) Effect of Termination. In the case of the Company’s termination of Executive’s employment for Cause or
Executive’s resignation from Executive’s employment without Good Reason, Executive shall be entitled to receive (i) Base Salary through the effective date of termination of employment, (ii) any benefits payable in connection with

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.

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. 

  
 - 10 -

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

 (e) Covenant Not to Compete. 

(i) Executive agrees that during the course of Executive’s employment and for a period of twelve (12) months immediately
following 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

maintains non-trivial operations, facilities, or customers in such geographic area prior to the date of the termination of Executive’s relationship with the Company. 
 (ii) Executive acknowledges that Executive’s fulfillment of the obligations contained in this 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

 (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. 
 (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.

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).

 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”) (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 

  
 - 13 -

 
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). 

(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 

  
 - 14 -

 
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.

become vested on the first anniversary of the Vesting Commencement Date and an additional one forty-eighth
(1/48th) of the shares of Common Stock subject to the
option shall become vested on the corresponding day of each calendar month thereafter or, to the extent such calendar month does not have the corresponding day, on the last day of such calendar month, until all such shares are vested and
exercisable, provided that the Optionee continues to be a Service Provider (as defined in the Company’s 2005 Stock Plan) on such dates. The Optionee shall be entitled to accelerated vesting as set forth in the Optionee’s employment
agreement with the Company and as set forth herein. 
 Termination Period: This Option shall be exercisable for three
(3) months after Optionee ceases to be a Service Provider. Upon Optionee’s death or Disability, this Option may be exercised for twelve (12) months after Optionee ceases to be a Service Provider. In no event may Optionee exercise this
Option after the Term/Expiration Date as provided above. 
 Accelerated Vesting: Notwithstanding anything herein to the
contrary, (i) the Shares subject to the Option shall vest on an accelerated basis in accordance with the terms of the Amended and Restated Employment Agreement dated as of December 31, 2007, by and between the Company the the Optionee, as
amended and/or restated from time to time after the date hereof, and (ii) in the event of a Change of Control (as defined in the Plan), all of the Shares subject to the Option shall vest on an accelerated basis as of the date immediately
preceding any Involuntary Termination (as defined below) of the Optionee occurring upon or after any such Change of Control. 

Stock Option Agreement—Early Exercise 

 “Involuntary Termination” shall mean (i) the Company’s
termination of Optionee’s status as a Service Provider other than for Cause (as defined below); (ii) without Optionee’s consent, a material reduction of the Optionee’s duties, authority or responsibilities, relative to the
Optionee’s duties, authority or responsibilities as in effect immediately prior to such reduction; provided, however, that any reduction in Optionee’s duties or responsibilities resulting solely from 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 a Change of Control but is not the chief financial officer of the acquiring corporation) shall
not constitute an Involuntary Termination; (iii) without Optionee’s consent, a material reduction in the base salary of the Optionee as in effect immediately prior to such reduction; (iv) without Optionee’s consent, a material
reduction by the Company in the kind or level of employee benefits, including bonuses, to which the Optionee was entitled immediately prior to such reduction, with the result that the Optionee’s overall benefits package is materially reduced;
or (v) without Optionee’s consent, the relocation of the Optionee to a facility or a location more than fifty (50) miles from the Optionee’s then present location. 

“Cause” shall mean (i) the Optionee’s continued failure to substantially perform the principal duties and
obligations of his or her position with the Company (other than any such failure resulting from incapacity due to physical or mental illness), which failure is not remedied in a reasonable period of time (but in any event not less than thirty
(30) business days) after receipt of written notice from the Company; (ii) any willful act of personal dishonesty, fraud or misrepresentation taken by the Optionee which was intended to result in substantial gain or personal enrichment of
the Optionee at the expense of the Company; (iii) the Optionee’s willful violation of a federal or state law or regulation applicable to the Company’s business which violation was or is reasonably likely to be materially and
demonstrably injurious to the Company; (iv) the Optionee’s conviction of a felony or a plea of nolo contendere under the laws of the United States or any State; or (v) the Optionee’s willful breach of the terms of the
Optionee’s confidentiality and assignment of inventions agreement with the Company, if any. For the purposes hereof, no act or failure to act shall be considered “willful” unless done or omitted to be done in bad faith and without
reasonable belief that the act or omission was in or not opposed to the best interests of the Company. 

 II. AGREEMENT 
 1. Grant of Option. 
 (a) The Administrator hereby grants to the Optionee
named in the Notice of Grant (the “Optionee”), an option (the “Option”) to purchase the number of Shares set forth in the Notice of Grant, at the exercise price per Share set forth in the Notice of Grant (the
“Exercise Price”), and subject to the terms and conditions of the Plan, which is incorporated herein by reference. Subject to Section 14(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan
and this Option Agreement, the terms and conditions of the Plan shall prevail. 
 (b) If designated in the Notice of Grant as an
Incentive Stock Option (“ISO”), this Option is intended to qualify as an Incentive Stock Option as defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds the $100,000 rule of Code Section 422(d),
this Option shall be treated as a Nonstatutory Stock Option (“NSO”). 
 2. Exercise of Option. This
Option shall be exercisable during its term in accordance with the provisions of Section 9 of the Plan as follows: 
 (a)
Right to Exercise. 
 (i) Subject to subsections 2(a)(ii) and 2(a)(iii) below, this Option shall be exercisable
cumulatively according to the vesting schedule set forth in the Notice of Grant. Alternatively, at the election of the Optionee, this Option may be exercised in whole or in part at any time as to Shares that have not yet vested. Vested Shares shall
not be subject to the Company’s repurchase right (as set forth in the Restricted Stock Purchase Agreement, attached hereto as Exhibit C-1). 
 (ii) As a condition to exercising this Option for unvested Shares, the Optionee shall execute the Restricted Stock Purchase Agreement. 

(iii) This Option may not be exercised for a fraction of a Share. 

(b) Method of Exercise. 
 (i) This Option shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A (the “Exercise Notice”) which shall state the election to exercise the
Option, the number of Shares with respect to which the Option is being exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by
payment of the aggregate Exercise Price as to all Exercised Shares. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price. 

(ii) No Shares shall be issued pursuant to the exercise of an Option unless such issuance and such exercise comply with Applicable Laws.
Assuming such compliance, for income tax purposes the Shares shall be considered transferred to the Optionee on the date on which the Option is exercised with respect to such Shares. 

  
 Stock Option
Agreement—Early Exercise 

 3. Optionee’s Representations. In the event the Shares have not been registered
under the Securities Act at the time this Option is exercised, the Optionee shall, if required by the Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement
in the form attached hereto as Exhibit B. 
 4. Market Standoff Agreement. Optionee hereby agrees that
Optionee shall not offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or
indirectly, any Common Stock (or other securities) of the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or other
securities) of the Company held by Optionee (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred eighty
(180) days following the effective date of any registration statement of the Company filed under the Securities Act. Optionee agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter
which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company, Optionee shall
provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s securities pursuant to a registration
statement filed under the Securities Act. The obligations described in this Section 4 shall not apply to a registration relating solely to (i) employee benefit plans or (ii) an SEC Rule 145 transaction. The Company may impose
stop-transfer instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said one hundred eighty (180) day period. Optionee agrees that any transferee of the Option or
shares acquired pursuant to the Option shall be bound by this Section 4. 
 5. Method of Payment. Payment of the
aggregate Exercise Price shall be by any of the following, or a combination thereof, at the election of the Optionee: 
 (a) cash
or check; 
 (b) consideration received by the Company under a formal cashless exercise program adopted by the Company in
connection with the Plan; or 
 (c) surrender of other Shares which, (i) in the case of Shares acquired from the Company,
either directly or indirectly, have been owned by the Optionee for more than six (6) months on the date of surrender, and (ii) have a Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the Exercised Shares.

 6. Restrictions on Exercise. This Option may not be exercised until such time as the Plan has been approved by the
stockholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any Applicable Law. 

7. Non-Transferability of Option. This Option may not be transferred in any manner otherwise than by will or by the laws of
descent or distribution and may be exercised during the lifetime of Optionee only by Optionee. The terms of the Plan and this Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee.

  
 Stock Option
Agreement—Early Exercise 

 8. Term of Option. This Option may be exercised only within the term set out in the
Notice of Grant, and may be exercised during such term only in accordance with the Plan and the terms of this Option. 
 9.
Tax Obligations. 
 (a) Withholding Taxes. Optionee agrees to make appropriate arrangements with the Company (or
the Parent or Subsidiary employing or retaining Optionee) for the satisfaction of all federal, state, local and foreign income and employment tax withholding requirements applicable to the Option exercise. Optionee acknowledges and agrees that the
Company may refuse to honor the exercise and refuse to deliver the Shares if such withholding amounts are not delivered at the time of exercise. 
 (b) Notice of Disqualifying Disposition of ISO Shares. If the Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise disposes of any of the Shares acquired pursuant to the
ISO on or before the later of (1) the date two years after the Date of Grant, and (2) the date one year after the date of exercise, the Optionee shall immediately notify the Company in writing of such disposition. Optionee agrees that
Optionee may be subject to income tax withholding by the Company on the compensation income recognized by the Optionee. 
 (c)
Code Section 409A. Under Code Section 409A, an Option that vests after December 31, 2004 that was granted with a per Share exercise price that is determined by the Internal Revenue Service (the “IRS”) to be
less than the fair market value of a Share on the date of grant (a “discount option”) is considered “deferred compensation.” An Option that is a “discount option” may result in (i) income recognition by the
Optionee prior to the exercise of the Option (when the Option vests), (ii) an additional twenty percent (20%) income tax, and (iii) potential interest charges. Optionee acknowledges that the Company cannot and has not guaranteed that
the IRS will determine that the per Share exercise price of this Option equals or exceeds the fair market value of a Share on the date of grant. Optionee agrees that if the IRS determines that the Option was granted with a per Share exercise price
that was less than the fair market value of a Share on the date of grant, Optionee will be solely responsibly for any of costs related to such a determination. 
 10. Entire Agreement; Governing Law. The Plan is incorporated herein by reference. The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject
matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing
signed by the Company and Optionee. This Option Agreement is governed by the internal substantive laws but not the choice of law rules of Texas. 
 11. No Guarantee of Continued Service. OPTIONEE AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE
COMPANY (NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING 

  
 Stock Option
Agreement—Early Exercise 

 
SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS OPTION AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN
EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH OPTIONEE’S RIGHT OR THE COMPANY’S RIGHT TO TERMINATE OPTIONEE’S
RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 
 Optionee acknowledges receipt of a copy of the Plan
and represents that he or she is familiar with the terms and provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Optionee has reviewed the Plan and this Option in their entirety, has had an
opportunity to obtain the advice of counsel prior to executing this Option and fully understands all provisions of the Option. Optionee hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator
upon any questions arising under the Plan or this Option. Optionee further agrees to notify the Company upon any change in the residence address indicated below.

undersigned (“Optionee”) hereby elects to exercise Optionee’s option (the “Option”) to purchase             shares of the Common Stock (the
“Shares”) of Mavenir Systems, Inc. (the “Company”) under and pursuant to the 2005 Stock Plan (the “Plan”) and the Stock Option Agreement dated
            ,             (the “Option Agreement”). 

2. Delivery of Payment. Optionee herewith delivers to the Company the full purchase price of the Shares as set forth in the Option
Agreement, and any and all withholding taxes due in connection with the exercise of the Option. 
 3. Representations of
Optionee. Optionee acknowledges that Optionee has received, read and understood the Plan and the Option Agreement and agrees to abide by and be bound by their terms and conditions. 

4. Rights as Stockholder. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or
of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Shares shall be issued to
the Optionee as soon as practicable after the Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend or other right for which the record date is prior to the date of issuance except as provided in
Section 12 of the Plan. 
 5. Company’s Right of First Refusal. Before any Shares held by Optionee or any
transferee (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal to
purchase the Shares on the terms and conditions set forth in this Section (the “Right of First Refusal”). 
 (a)
Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares;
(ii) the name of each proposed purchaser or other transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other consideration
for which the Holder proposes to transfer the Shares (the “Offered Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s). 

 (b) Exercise of Right of First Refusal. At any time within thirty (30) days
after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase up to all of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price
determined in accordance with subsection (c) below. 
 (c) Purchase Price. The purchase price (“Purchase
Price”) for the Shares purchased by the Company or its assignee(s) under this Section shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith. 
 (d) Payment. Payment of the Purchase Price shall be
made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an assignee, to the assignee), or by any
combination thereof within 30 days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (e)
Holder’s Right to Transfer. To the extent that the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section, then the Holder may
sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within 120 days after the date of the Notice, that any such sale or other transfer
is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this Section shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares
described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by
the Holder may be sold or otherwise transferred. 
 (f) Exception for Certain Family Transfers. Anything to the contrary
contained in this Section notwithstanding, the transfer of any or all of the Shares during the Optionee’s lifetime or on the Optionee’s death by will or intestacy to the Optionee’s immediate family or a trust for the benefit of the
Optionee’s immediate family shall be exempt from the provisions of this Section. “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the
transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section, and there shall be no further transfer of such Shares except in accordance with the terms of this Section. 

(g) Termination of Right of First Refusal. The Right of First Refusal shall terminate as to any Shares upon the first sale of
Common Stock of the Company to the general public pursuant to a registration statement filed with and declared effective by the Securities and Exchange Commission under the Securities Act. 

6. Tax Consultation. Optionee understands that Optionee may suffer adverse tax consequences as a result of Optionee’s
purchase or disposition of the Shares. Optionee represents that Optionee has consulted with any tax consultants Optionee deems advisable in connection with the purchase or disposition of the Shares and that Optionee is not relying on the Company for
any tax advice.

its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 
 (c) Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this

 In connection with the purchase of the above-listed Securities, the undersigned Optionee represents to
the Company the following: 
 (a) Optionee is aware of the Company’s business affairs and financial condition and has
acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Optionee is acquiring these Securities for investment for Optionee’s own account only and not with a view to, or for
resale in connection with, any “distribution” thereof within the meaning of the Securities Act. 
 (b) Optionee
acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends
upon, among other things, the bona fide nature of Optionee’s investment intent as expressed herein. In this connection, Optionee understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may
be unavailable if Optionee’s representation was predicated solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in
the market price of the Securities, or for a period of one year or any other fixed period in the future. Optionee further understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or
an exemption from such registration is available. Optionee further acknowledges and understands that the Company is under no obligation to register the Securities. Optionee understands that the certificate evidencing the Securities will be imprinted
with the legends set forth in Section 7(a) of the Exercise Notice and with any other legend required under applicable state securities laws. 
 (c) Optionee is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted
securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of the grant
of the Option to the Optionee, the exercise will be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety
(90) days thereafter (or such longer period as any market stand-off agreement may require) the Securities exempt under Rule 701 

 
may be resold, subject to the satisfaction of certain of the conditions specified by Rule 144, including (1) the resale being made through a broker in an unsolicited “broker’s
transaction” or in transactions directly with a market maker (as said term is defined under the Securities Exchange Act of 1934); and, in the case of an affiliate, (2) the availability of certain public information about the Company,
(3) the amount of Securities being sold during any three month period not exceeding the limitations specified in Rule 144(e), and (4) the timely filing of a Form 144, if applicable. 

In the event that the Company does not qualify under Rule 701 at the time of grant of the Option, then the Securities may be resold
in certain limited circumstances subject to the provisions of Rule 144, which requires the resale to occur not less than one year after the later of the date the Securities were sold by the Company or the date the Securities were sold by
an affiliate of the Company, within the meaning of Rule 144; and, in the case of acquisition of the Securities by an affiliate, or by a non-affiliate who subsequently holds the Securities less than two years, the satisfaction of the conditions
set forth in sections (1), (2), (3) and (4) of the paragraph immediately above. 
 (d) Optionee further understands
that in the event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the
fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant
to Rules 144 or 701 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at
their own risk. Optionee understands that no assurances can be given that any such other registration exemption will be available in such event.

MAVENIR SYSTEMS, INC. 
 2005 STOCK PLAN 
 RESTRICTED STOCK PURCHASE AGREEMENT 

THIS AGREEMENT is made between             (the “Purchaser”)
and Mavenir Systems, Inc. (the “Company”) or its assignees of rights hereunder as of             ,             .

 Unless otherwise defined herein, the terms defined in the 2005 Stock Plan shall have the same defined meanings in this
Agreement. 
 RECITALS 
 A. Pursuant to the exercise of the option granted to Purchaser under the Plan and pursuant to the Option Agreement dated             by and
between the Company and Purchaser with respect to such grant (the “Option”), which Plan and Option Agreement are hereby incorporated by reference, Purchaser has elected to purchase
            of those shares of Common Stock which have not become vested under the vesting schedule set forth in the Option Agreement (“Unvested Shares”). The Unvested
Shares and the shares subject to the Option Agreement that have become vested are sometimes collectively referred to herein as the “Shares.” 
 B. As required by the Option Agreement, as a condition to Purchaser’s election to exercise the option, Purchaser must execute this Agreement, which sets forth the rights and obligations of the
parties with respect to Shares acquired upon exercise of the Option. 
 1. Repurchase Option. 

(a) If Purchaser’s status as a Service Provider is terminated for any reason, including for death and Disability, the Company shall
have the right and option for ninety (90) days from such date to purchase from Purchaser, or Purchaser’s personal representative, as the case may be, all of the Purchaser’s Unvested Shares as of the date of such termination at the
lower of (i) the fair market value of the Unvested Shares on the date of repurchase and (ii) the price paid by the Purchaser for such Shares (the “Repurchase Option”). 

(b) Upon the occurrence of such termination, the Company may exercise its Repurchase Option by delivering personally or by registered
mail, to Purchaser (or his transferee or legal representative, as the case may be) with a copy to the Escrow Agent described in Section 2 below, a notice in writing indicating the Company’s intention to exercise the Repurchase Option AND,
at the Company’s option, (i) by delivering to the Purchaser (or the Purchaser’s transferee or legal representative) a check in the amount of the aggregate repurchase price, (ii) by the Company canceling an amount of the
Purchaser’s indebtedness to the Company equal to the aggregate repurchase price or (iii) by a combination of (i) and (ii) so that the combined payment and cancellation of indebtedness equals such aggregate repurchase price. Upon
delivery of such notice and payment of the aggregate repurchase price in any of the ways described above, the Company 

 
shall become the legal and beneficial owner of the Unvested Shares being repurchased and the rights and interests therein or relating thereto, and the Company shall have the right to retain and
transfer to its own name the number of Unvested Shares being repurchased by the Company. 
 (c) Whenever the Company shall have
the right to repurchase Unvested Shares hereunder, the Company may designate and assign one or more employees, officers, directors or stockholders of the Company or other persons or organizations to exercise all or a part of the Company’s
Repurchase Option under this Agreement and purchase all or a part of such Unvested Shares. 
 (d) If the Company does not elect
to exercise the Repurchase Option conferred above by giving the requisite notice within ninety (90) days following the termination, the Repurchase Option shall terminate. 
 (e) The Repurchase Option shall terminate in accordance with the vesting schedule contained in Purchaser’s Option Agreement. 
 2. Transferability of the Shares; Escrow. 
 (a) Purchaser hereby authorizes
and directs the Secretary of the Company, or such other person designated by the Company, to transfer the Unvested Shares as to which the Repurchase Option has been exercised from Purchaser to the Company. 

(b) To insure the availability for delivery of Purchaser’s Unvested Shares upon repurchase by the Company pursuant to the Repurchase
Option under Section 1, Purchaser hereby appoints the Secretary, or any other person designated by the Company as Escrow Agent (the “Escrow Agent”), as its attorney-in-fact to sell, assign and transfer unto the Company, such
Unvested Shares, if any, repurchased by the Company pursuant to the Repurchase Option and shall, upon execution of this Agreement, deliver and deposit with the Escrow Agent, the share certificates representing the Unvested Shares, together with the
stock assignment duly endorsed in blank, attached hereto as Exhibit C-2. The Unvested Shares and stock assignment shall be held in escrow by the Escrow Agent, pursuant to the Joint Escrow Instructions of the Company and Purchaser attached as
Exhibit C-3 hereto, until the Company exercises its Repurchase Option, until such Unvested Shares are vested, or until such time as this Agreement no longer is in effect. As a further condition to the Company’s obligations under
this Agreement, the spouse of the Purchaser, if any, shall execute and deliver to the Company the Consent of Spouse attached hereto as Exhibit C-4. Upon vesting of the Unvested Shares, the Escrow Agent shall promptly deliver to the Purchaser
the certificate or certificates representing such Shares in the Escrow Agent’s possession belonging to the Purchaser, and the Escrow Agent shall be discharged of all further obligations hereunder; provided, however, that the Escrow Agent shall
nevertheless retain such certificate or certificates as Escrow Agent if so required pursuant to other restrictions imposed pursuant to this Agreement. 
 (c) Neither the Company nor the Escrow Agent shall be liable for any act it may do or omit to do with respect to holding the Shares in escrow and while acting in good faith and in the exercise of its
judgment. 
 (d) Transfer or sale of the Shares is subject to restrictions on transfer imposed by any applicable state and
federal securities laws. Any transferee shall hold such Shares subject to all the provisions hereof and the Exercise Notice executed by the Purchaser with respect to any Unvested Shares purchased by Purchaser and shall acknowledge the same by
signing a copy of this Agreement.

 3. Ownership, Voting Rights, Duties. This Agreement shall not affect in any way the
ownership, voting rights or other rights or duties of Purchaser, except as specifically provided herein. 
 4. Legends.
The share certificate evidencing the Shares issued hereunder shall be endorsed with the following legend (in addition to any legend required under applicable federal and state securities laws): 

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS
OF ANY STATE, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SUCH ACT AND/OR APPLICABLE STATE SECURITIES LAWS, OR UNLESS, IN THE OPINION OF COUNSEL (WHICH MAY BE COUNSEL TO THE CORPORATION)
SATISFACTORY TO THE CORPORATION, SUCH REGISTRATION IS NOT REQUIRED. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
CERTAIN RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN AGREEMENT BETWEEN THE CORPORATION AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. 

5. Adjustment for Stock Split. All references to the number of Shares and the purchase price of the Shares in this Agreement shall
be appropriately adjusted to reflect any stock split, stock dividend or other change in the Shares that may be made by the Company pursuant to Section 12 of the Plan after the date of this Agreement. 

6. Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be delivered
personally by hand or by courier, mailed by United States first-class mail, postage prepaid, sent by facsimile or sent by electronic mail directed (a) if to the Purchaser, at the Purchaser’s address, facsimile number or electronic mail
address set forth on the signature page to the Option Agreement, or at such other address, facsimile number or electronic mail address as the Purchaser may designate by ten (10) days’ advance written notice to the Company or (b) if to
the Company, to the address of its principal executive office, or at such other address as the Company may designate by ten (10) days’ advance written notice to the Purchaser. All such notices and other communications shall be deemed given
upon personal delivery, on the date of mailing, upon confirmation of facsimile transfer or when directed to the electronic mail address set forth on the signature page to the Option Agreement. With respect to any notice given by the Company under
any provision of the Texas Business Corporation Act or the Company’s charter or bylaws, the Purchaser agrees that such notice may given by facsimile or by electronic mail. 

  
 -3-

 7. Survival of Terms. This Agreement shall apply to and bind Purchaser and the
Company and their respective permitted assignees and transferees, heirs, legatees, executors, administrators and legal successors. 
 8. Section 83(b) Election. Purchaser hereby acknowledges that he or she has been informed that, with respect to the exercise of an Option for Unvested Shares, an election (the
“Election”) may be filed by the Purchaser with the Internal Revenue Service, within 30 days of the purchase of the exercised Shares, electing pursuant to Section 83(b) of the Code to be taxed currently on any difference between
the purchase price of the exercised Shares and their Fair Market Value on the date of purchase. In the case of a Nonstatutory Stock Option, this will result in a recognition of taxable income to the Purchaser on the date of exercise, measured by the
excess, if any, of the Fair Market Value of the exercised Shares, at the time the Option is exercised over the purchase price for the exercised Shares. Absent such an Election, taxable income will be measured and recognized by Purchaser at the time
or times on which the Company’s Repurchase Option lapses. In the case of an Incentive Stock Option, such an Election will result in a recognition of income to the Purchaser for alternative minimum tax purposes on the date of exercise, measured
by the excess, if any, of the Fair Market Value of the exercised Shares, at the time the option is exercised, over the purchase price for the exercised Shares. Absent such an Election, alternative minimum taxable income will be measured and
recognized by Purchaser at the time or times on which the Company’s Repurchase Option lapses. Purchaser is strongly encouraged to seek the advice of his or her own tax consultants in connection with the purchase of the Shares and the
advisability of filing of the Election under Section 83(b) of the Code. A form of Election under Section 83(b) is attached hereto as Exhibit C-5 for reference. 
 PURCHASER ACKNOWLEDGES THAT IT IS PURCHASER’S SOLE RESPONSIBILITY AND NOT THE COMPANY’S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b) OF THE CODE, EVEN IF PURCHASER REQUESTS THE
COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON PURCHASER’S BEHALF. 
 9. Representations. Purchaser
has reviewed with his own tax advisors the federal, state, local and foreign tax consequences of this investment and the transactions contemplated by this Agreement. Purchaser is relying solely on such advisors and not on any statements or
representations of the Company or any of its agents. Purchaser understands that he (and not the Company) shall be responsible for his own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement.

 10. Governing Law. This Agreement shall be governed by the internal substantive laws, but not the choice of law rules,
of Texas. 
 Purchaser represents that he has read this Agreement and is familiar with its terms and provisions. Purchaser
hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Board upon any questions arising under this Agreement.

Attn: Secretary 
 Dear Secretary: 

As Escrow Agent for both Mavenir Systems, Inc. (the “Company”), and the undersigned purchaser of stock of the Company
(the “Purchaser”), you are hereby authorized and directed to hold the documents delivered to you pursuant to the terms of that certain Restricted Stock Purchase Agreement (“Agreement”) between the Company and the
undersigned, in accordance with the following instructions: 
 1. In the event the Company and/or any assignee of the Company
(referred to collectively for convenience herein as the “Company”) exercises the Company’s repurchase option set forth in the Agreement, the Company shall give to Purchaser and you a written notice specifying the number of
shares of stock to be purchased, the purchase price, and the time for a closing hereunder at the principal office of the Company. Purchaser and the Company hereby irrevocably authorize and direct you to close the transaction contemplated by such
notice in accordance with the terms of said notice. 
 2. At the closing, you are directed (a) to date the stock
assignments necessary for the transfer in question, (b) to fill in the number of shares being transferred, and (c) to deliver the stock assignments, together with the certificate evidencing the shares of stock to be transferred, to the
Company or its assignee, against the simultaneous delivery to you of the purchase price (by cash, a check, or some combination thereof) for the number of shares of stock being purchased pursuant to the exercise of the Company’s repurchase
option. 
 3. Purchaser irrevocably authorizes the Company to deposit with you any certificates evidencing shares of stock to be
held by you hereunder and any additions and substitutions to said shares as defined in the Agreement. Purchaser does hereby irrevocably constitute and appoint you as Purchaser’s attorney-in-fact and agent for the term of this escrow to execute
with respect to such securities all documents necessary or appropriate to make such securities negotiable and to complete any transaction herein contemplated, including but not limited to the filing with any applicable state blue sky authority of
any required applications for consent to, or notice of transfer of, the securities. Subject to the provisions of this paragraph 3, Purchaser shall exercise all rights and privileges of a stockholder of the Company while the stock is held by
you. 
 4. Upon written request of the Purchaser, but no more than once per calendar year, unless the Company’s repurchase
option has been exercised, you will deliver to Purchaser a certificate or certificates representing so many shares of stock as are not then subject to the Company’s repurchase option. Within 120 days after cessation of Purchaser’s
continuous 

 
employment by or services to the Company, or any parent or subsidiary of the Company, you will deliver to Purchaser a certificate or certificates representing the aggregate number of shares held
or issued pursuant to the Agreement and not purchased by the Company or its assignees pursuant to exercise of the Company’s repurchase option. 
 5. If at the time of termination of this escrow you should have in your possession any documents, securities or other property belonging to Purchaser, you shall deliver all of the same to Purchaser and
shall be discharged of all further obligations hereunder. 
 6. Your duties hereunder may be altered, amended, modified or
revoked only by a writing signed by all of the parties hereto. 
 7. You shall be obligated only for the performance of such
duties as are specifically set forth herein and may rely and shall be protected in relying or refraining from acting on any instrument reasonably believed by you to be genuine and to have been signed or presented by the proper party or parties. You
shall not be personally liable for any act you may do or omit to do hereunder as Escrow Agent or as attorney-in-fact for Purchaser while acting in good faith, and any act done or omitted by you pursuant to the advice of your own attorneys shall be
conclusive evidence of such good faith. 
 8. You are hereby expressly authorized to disregard any and all warnings given by any
of the parties hereto or by any other person or corporation, excepting only orders or process of courts of law and are hereby expressly authorized to comply with and obey orders, judgments or decrees of any court. In case you obey or comply with any
such order, judgment or decree, you shall not be liable to any of the parties hereto or to any other person, firm or corporation by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified,
annulled, set aside, vacated or found to have been entered without jurisdiction. 
 9. You shall not be liable in any respect on
account of the identity, authorities or rights of the parties executing or delivering or purporting to execute or deliver the Agreement or any documents or papers deposited or called for hereunder. 

10. You shall not be liable for the outlawing of any rights under the Statute of Limitations with respect to these Joint Escrow
Instructions or any documents deposited with you. 
 11. You shall be entitled to employ such legal counsel and other experts as
you may deem necessary properly to advise you in connection with your obligations hereunder, may rely upon the advice of such counsel, and may pay such counsel reasonable compensation therefor. 

12. Your responsibilities as Escrow Agent hereunder shall terminate if you shall cease to be an officer or agent of the Company or if you
shall resign by written notice to each party. In the event of any such termination, the Company shall appoint a successor Escrow Agent. 
 13. If you reasonably require other or further instruments in connection with these Joint Escrow Instructions or obligations in respect hereto, the necessary parties hereto shall join in furnishing such
instruments.

 14. It is understood and agreed that should any dispute arise with respect to the delivery
and/or ownership or right of possession of the securities held by you hereunder, you are authorized and directed to retain in your possession without liability to anyone all or any part of said securities until such disputes shall have been settled
either by mutual written agreement of the parties concerned or by a final order, decree or judgment of a court of competent jurisdiction after the time for appeal has expired and no appeal has been perfected, but you shall be under no duty
whatsoever to institute or defend any such proceedings. 
 15. Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given upon personal delivery or upon deposit in the United States Post Office, by registered or certified mail with postage and fees prepaid, addressed to each of the other parties thereunto entitled at the
following addresses or at such other addresses as a party may designate by ten days’ advance written notice to each of the other parties hereto. 
 16. By signing these Joint Escrow Instructions, you become a party hereto only for the purpose of said Joint Escrow Instructions; you do not become a party to the Agreement. 

17. This instrument shall be binding upon and inure to the benefit of the parties hereto, and their respective successors and permitted
assigns. 
 18. These Joint Escrow Instructions shall be governed by the internal substantive laws, but not the choice of law
rules, of Texas.
