Form of Indemnification Agreement

 Exhibit 10.1 
 MAVENIR SYSTEMS, INC. 
 INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (“Agreement”) is effective as of
[            , 20        ], by and between Mavenir Systems, Inc., a Delaware corporation (the “Company”), and
[            ] (“Indemnitee”). 
 A. The
Company recognizes the continued difficulty in obtaining liability insurance for its directors, officers, employees, controlling persons, fiduciaries and other agents and affiliates, the significant increases in the cost of such insurance and the
general reductions in the coverage of such insurance. 
 B. The Company further recognizes the substantial increase in corporate
litigation in general, subjecting directors, officers, employees, controlling persons, fiduciaries and other agents and affiliates to expensive litigation risks at the same time as the availability and coverage of liability insurance has been
severely limited. 
 C. The current protection available to directors, officers, employees, controlling persons, fiduciaries and
other agents and affiliates of the Company may not be adequate under the present circumstances, and directors, officers, employees, controlling persons, fiduciaries and other agents and affiliates of the Company (or persons who may be alleged or
deemed to be the same), including Indemnitee, may not be willing to continue to serve or be associated with the Company in such capacities without additional protection. 
 D. The Company (a) desires to attract and retain the involvement of highly qualified persons, such as Indemnitee, to serve and be associated with the Company and, accordingly, (b) wishes to
provide for the indemnification and advancement of expenses to Indemnitee to the maximum extent permitted by applicable law. 

E. In view of the considerations set forth above, the Company desires that Indemnitee shall be indemnified and advanced expenses by the
Company as set forth herein. 
 In consideration of the mutual promises and covenants contained herein, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
 1. Definitions. 

(a) “Bylaws” means the Company’s Bylaws as currently in effect, as hereafter amended or amended and restated
from time to time. 
 (b) “Certificate of Incorporation” means the Company’s Certificate of
Incorporation as currently in effect, as hereafter amended or amended and restated from time to time. 

 (c) “Change in Control” shall be deemed to have occurred if, on or
after the date of this Agreement, (i) any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act), other than a trustee or other fiduciary holding securities under an employee benefit plan of the Company acting
in such capacity or a corporation owned directly or indirectly by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company, becomes the “beneficial owner” (as defined in
Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing more than thirty percent (30%) of the total voting power represented by the Company’s then outstanding Voting Securities (as defined
below); (ii) during any period of two (2) consecutive years (not including any period prior to the execution of this Agreement), individuals who at the beginning of such period constitute the Board of Directors of the Company and any new
director (other than a director designated by a person who has entered into an agreement with the Company to effect a transaction described in Sections 1(c)(i), 1(c)(iii) or 1(c)(iv) herein) whose election by the Board of
Directors or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds (2/3) of the directors then still in office who either were directors at the beginning of the period or whose election or
nomination for election was previously so approved, cease for any reason to constitute a majority thereof; (iii) the stockholders of the Company approve a merger or consolidation of the Company with any other corporation other than a merger or
consolidation which would result in the Voting Securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into Voting Securities of the surviving entity) at least
eighty percent (80%) of the total voting power represented by the Voting Securities of the Company or such surviving entity outstanding immediately after such merger or consolidation; or (iv) the stockholders of the Company approve a plan of
complete liquidation of the Company or an agreement for the sale or disposition by the Company of (in one transaction or a series of related transactions) all or substantially all of the Company’s assets. 

(d) “Claim” means with respect to an Indemnification Event, any threatened, asserted, pending or completed
action, suit, proceeding or alternative dispute resolution mechanism, whether brought in the right of the Company or otherwise, or any hearing, inquiry or investigation (formal or informal) that Indemnitee in good faith believes might lead to the
institution of any such action, suit, proceeding or alternative dispute resolution mechanism, whether civil, criminal, administrative, investigative or other, including any appeal therefrom. 

(e) References to the “Company” includes, in addition to Mavenir Systems, Inc., any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or merger to which the Company (or any of its wholly owned subsidiaries) is a party, which, if its separate existence had continued, would have had the power and authority to
indemnify its directors, trustees, partners, managing members, officers, employees, agents or fiduciaries, so that if Indemnitee is or was a director, trustee, partner, managing member, officer, employee, agent or fiduciary of such constituent
corporation, or is or was serving at the request of such constituent corporation as a director, trustee, partner, managing member, officer, employee, agent or fiduciary of another corporation, partnership, joint venture, employee benefit plan, trust
or other enterprise, Indemnitee shall stand in the same position under the provisions of this Agreement with respect to the resulting or surviving corporation as Indemnitee would have with respect to such constituent corporation if its separate
existence had continued.

Delaware.

other costs, expenses and obligations incurred in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to defend, to be a witness in or to participate in, any action, suit, proceeding,
alternative dispute resolution mechanism, hearing, inquiry or investigation), judgments, fines, penalties and amounts paid in settlement (if such settlement is approved in advance by the Company, which approval shall not be unreasonably withheld)

in connection with any appeal resulting from any Claim, including without limitation the premium, security for, and other costs relating to any cost bond, supersedeas bond, or other appeal bond or its equivalent; (ii) Expenses incurred in connection
with recovery under any directors’ and officers’ liability insurance policies maintained by the Company, regardless of whether Indemnitee is ultimately determined to be entitled to such indemnification, advancement of Expenses or insurance
recovery, as the case may be; and (iii) for purposes of Section 13(e) only, Expenses incurred by or on behalf of Indemnitee in connection with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement, by
litigation or otherwise. The parties agree that for the purposes of any advancement of Expenses for which Indemnitee has made written demand to the Company in accordance with this Agreement, all Expenses included in such demand that are certified by

matters concerning the rights of Indemnitee under this Agreement, or of other indemnitees under similar indemnity agreements); or (ii) any other party to the Claim giving rise to a claim for indemnification under this Agreement, within the last
three (3) years. Notwithstanding the foregoing, the term “Independent Legal Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in

to be in the interest of the participants and beneficiaries of an employee benefit plan, Indemnitee shall be deemed to have acted in a manner “not opposed to the best interests of the Company” as referred to in this
Agreement.

2. Indemnification. 
 (a) Indemnification of Expenses. 

  
 -4-

 (i) Subject to the provisions of Section 2(b) below, the Company shall
indemnify Indemnitee for Expenses to the fullest extent permitted by applicable law if Indemnitee was or is or becomes a party or potential party to or witness or other participant in, or is threatened to be made a party to or other participant in,
any Claim (whether by reason of or arising in part out of an Indemnification Event), including all interest, assessments and other charges incurred in connection with or in respect of such Expenses. The parties hereto intend that this Agreement
shall provide to the fullest extent permitted by applicable law for indemnification in excess of that expressly permitted by statute, including, without limitation, any indemnification provided by the Certificate of Incorporation, the Bylaws, or by
statute, any other agreement, a vote of its stockholders or disinterested directors, or otherwise. 
 (ii) Notwithstanding any
other provision of this Agreement, to the fullest extent permitted by applicable law and to the extent that Indemnitee is, by reason of an Indemnification Event, a witness or otherwise asked to participate in any aspect of a Claim to which
Indemnitee is not a party, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. 

(b) Review of Indemnification Obligations. 
 (i) Notwithstanding the foregoing, in the event any Reviewing Party shall have determined (in a written opinion, in any case in which Independent Legal Counsel is the Reviewing Party) that Indemnitee is
not entitled to be indemnified under this Agreement under applicable law, (A) the Company shall have no further obligation under Section 2(a) to make any payments to Indemnitee not made prior to such determination by such Reviewing
Party; and (B) the Company shall be entitled to be reimbursed by Indemnitee (who hereby agrees to reimburse the Company) for all Expenses theretofore paid in indemnifying Indemnitee (within thirty (30) days after the Indemnitee receives
notice of such determination); provided, however, that if Indemnitee has commenced or thereafter commences legal proceedings in a court of competent jurisdiction to secure a determination that Indemnitee is entitled to be indemnified
under this Agreement under applicable law, any determination made by any Reviewing Party that Indemnitee is not entitled to be indemnified under this Agreement under applicable law shall not be binding and Indemnitee shall not be required to
reimburse the Company for any Expenses theretofore paid in indemnifying Indemnitee unless, until and only to the extent that a final judicial determination is made with respect thereto (as to which all rights of appeal therefrom have been exhausted
or lapsed) and until such time, Indemnitee shall be entitled to receive interim payments of expenses pursuant to this Section 2. Indemnitee’s obligation to reimburse the Company for any Expenses shall be unsecured and no interest
shall be charged thereon. 
 (ii) Subject to Section 2(b)(iii) below, if the Reviewing Party shall not have made a
determination within forty-five (45) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall, to the fullest extent not prohibited by applicable law, be deemed to have been
made and Indemnitee shall be entitled to such indemnification, absent (A) a misstatement by Indemnitee of a material fact, or Indemnitee’s omission of a material fact necessary to make Indemnitee’s statement not materially misleading,
in connection with the request for indemnification; or (B) a prohibition of such indemnification under applicable law; provided, however, that such forty-five (45) day period may be extended for a reasonable time, not to
exceed an additional thirty (30) days, if the 

  
 -5-

 
Reviewing Party in good faith requires such additional time for the obtaining or evaluating of documentation and/or information relating thereto. In the event that the Reviewing Party extends the
forty-five (45) day review period, the Company will provide written notice of such extension to the Indemnitee. 
 (iii)
Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement of Indemnitee to indemnification under this Agreement shall be required to be made prior to the final disposition of the Claim. 

(c) Indemnitee Rights on Unfavorable Determination; Binding Effect. If any Reviewing Party determines that Indemnitee
substantively is not entitled to be indemnified under this Agreement in whole or in part under applicable law, Indemnitee shall have the right to commence litigation seeking an initial determination by the court or challenging any such determination
by such Reviewing Party or any aspect thereof, including the legal or factual bases therefor, and, subject to the provisions of Section 15, the Company hereby consents to service of process and to appear in any such proceeding. Absent
such litigation, any determination by any Reviewing Party shall be conclusive and binding on the Company and Indemnitee. 
 (d)
Selection of Reviewing Party; Change in Control. If there has not been a Change in Control, any Reviewing Party shall be selected (i) by a majority vote of the directors of the Company who are not and were not a party to the Claim
in respect of which indemnification is sought by Indemnitee (“Disinterested Directors”), even if less than a quorum of the Board; (ii) by a committee of Disinterested Directors designated by a majority vote of the
Disinterested Directors, even if less than a quorum of the Board; (iii) if there are no such Disinterested Directors or, if such Disinterested Directors so direct, by Independent Legal Counsel in a written opinion to the Board, a copy of which
shall be delivered to Indemnitee; or (iv) if so directed by the Board, by the stockholders of the Company; and if there has been such a Change in Control (other than a Change in Control which has been approved by a majority of the
Company’s Board of Directors who were directors immediately prior to such Change in Control), any Reviewing Party with respect to all matters thereafter arising concerning Indemnitee’s indemnification rights for Expenses under this
Agreement or any other agreement or under the Certificate of Incorporation or Bylaws as now or hereafter in effect, or under any other applicable law, if desired by Indemnitee, shall be Independent Legal Counsel selected by Indemnitee and approved
by the Company (which approval shall not be unreasonably withheld). Such counsel, among other things, shall render its written opinion to the Company and Indemnitee as to whether and to what extent Indemnitee would be entitled to be indemnified
under this Agreement under applicable law and the Company agrees to abide by such opinion. The Company agrees to pay the reasonable fees of the Independent Legal Counsel referred to above and to fully indemnify such counsel against any and all
expenses (including attorneys’ fees), claims, liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto. Notwithstanding any other provision of this Agreement, the Company shall not be required
to pay Expenses of more than one Independent Legal Counsel in connection with all matters concerning a single Indemnitee, and such Independent Legal Counsel shall be the Independent Legal Counsel for any or all other Indemnitees unless (A) the
Company otherwise determines; or (B) any Indemnitee shall provide a written statement setting forth in detail a reasonable objection to such Independent Legal Counsel representing other Indemnitees.

 (e) Mandatory Payment of Expenses. Notwithstanding any other provision of this
Agreement other than Section 10 hereof, to the fullest extent permitted by applicable law and to the extent that Indemnitee was a party to (or participant in) and has been successful on the merits or otherwise, in any Claim or in defense
of any claim, issue or matter therein, in whole or in part, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee in connection therewith. If Indemnitee is not wholly successful in such Claim but is
successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Claim, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s
behalf in connection with or related to each successfully resolved claim, issue or matter to the fullest extent permitted by applicable law. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a
Claim by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 

(f) Contribution. 
 (i) To the fullest extent permitted by applicable law, if the indemnification rights provided for in this Agreement are for any reason whatsoever unavailable to an Indemnitee, then in lieu of indemnifying
Indemnitee thereunder, the Company shall contribute to the amount incurred by or on behalf of Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, including all interest,
assessments and other charges incurred in connection with or in respect of such Expenses (i) in such proportion as is deemed fair and reasonable in light of all of the circumstances in order to reflect the relative benefits received by the
Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Claim; or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and its directors, officers, employees and agents, other than Indemnitee, on the one hand, and of the Indemnitee alone, on the other hand,
in connection with the action or inaction which resulted in such Expenses, as well as any other relevant equitable considerations. In connection with any registration of the Company’s securities under any securities laws (including,
without limitation, under the Securities Act or the Exchange Act), the relative benefits received by the Company and Indemnitee shall be deemed to be in the same respective proportions that the net proceeds from the relevant registered offering(s)
(before deducting expenses) received by the Company and Indemnitee, in each case as set forth in the applicable prospectus, bear to the aggregate public offering price of the securities so offered. The relative fault of the Company and its
directors, officers, employees and agents, other than Indemnitee, on the one hand, and of the Indemnitee alone, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or its directors, officers, employees and agents, other than Indemnitee, or supplied by the Indemnitee and the parties’ relative
intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 
 (ii) The Company
and Indemnitee agree that it would not be just and equitable if contribution pursuant to this Section 2(f) were determined by pro rata or by any other method of allocation which does not take account of the equitable considerations
referred to in 

  
 -7-

 
the immediately preceding paragraph. In connection with the registration of the Company’s securities, in no event shall Indemnitee be required to contribute any amount under this
Section 2(f) in excess of the net proceeds received by Indemnitee from Indemnitee’s sale of securities under such registration statement. No person found guilty of fraudulent misrepresentation (within the meaning of Section 12
of the Securities Act) shall be entitled to contribution from any person who was not found guilty of such fraudulent misrepresentation. 
 3. Expense Advances. Notwithstanding any provision of this Agreement to the contrary, the Company shall make Expense Advances, to the extent not prohibited by applicable law, to an
Indemnitee in connection with any Claim (or any part of any Claim) not initiated by Indemnitee, and such advancement shall be made within twenty (20) days after the receipt by the Company of a statement or statements requesting such advances
from time to time (which shall include invoices received by Indemnitee in connection with such Expenses but, in the case of invoices in connection with legal services, any references to legal work performed or to expenditures made that would cause
Indemnitee to waive any privilege accorded by applicable law shall not be so included), whether prior to or after final disposition of any Claim. Expense Advances shall be unsecured and interest free. Expense Advances shall be made without regard to
Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to indemnification under the other provisions of this Agreement. In accordance with Section 13(e), advances shall include any
and all Expenses incurred pursuing an action to enforce this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed. Indemnitee shall qualify for advances upon the
execution and delivery to the Company of this Agreement, which shall constitute an undertaking providing that Indemnitee undertakes to repay the amounts advanced (without interest) to the extent that it is ultimately determined that Indemnitee is
not entitled to be indemnified by the Company. No other form of undertaking shall be required other than the execution of this Agreement. This Section 3 shall not apply to any claim made by Indemnitee for which indemnity is excluded
pursuant to Section 10. 
 4. Procedures for Indemnification and Expense Advances. 

(a) Timing of Payments. All payments of Expenses by the Company to Indemnitee pursuant to this Agreement shall be made to
the fullest extent permitted by applicable law as soon as practicable after written demand by Indemnitee therefor is presented to the Company, but in no event later than forty-five (45) days after such written demand by Indemnitee is presented
to the Company, except in the case of Expense Advances, which shall be paid in accordance with Section 3 of this Agreement. If the Company disputes a portion of the amounts for which indemnification is requested, the undisputed portion
shall be paid and only the disputed portion withheld pending resolution of any such dispute. 
 (b) Notice/Cooperation by
Indemnitee. Indemnitee shall give the Company notice in writing as soon as practicable of any Claim made against Indemnitee for which indemnification or Expense Advances will or could be sought under this Agreement. Notice to

  
 -8-

 
the Company shall be directed to the President or Chief Executive Officer of the Company at the address shown on the signature page of this Agreement (or such other address as the Company shall
designate in writing to Indemnitee) and shall include a summary description of the nature of the Claim and the facts underlying the Claim, in each case to the extent reasonably known to and understood by Indemnitee. To obtain indemnification under
this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent
Indemnitee is entitled to indemnification following the final disposition of such Claim. In addition, Indemnitee shall give the Company such information and cooperation as it may reasonably require and as shall be within Indemnitee’s
power. The failure by Indemnitee to notify the Company under this Agreement will not relieve the Company from any liability which it may have to Indemnitee under this Agreement or otherwise than under this Agreement, and any delay in so
notifying the Company shall not constitute a waiver by Indemnitee of any rights under this Agreement, except to the extent (solely with respect to the indemnity under this Agreement) that such failure or delay materially prejudices the Company.

 (c) Presumptions and Effect of Certain Proceedings. 

(i) In making a determination with respect to entitlement to indemnification under this Agreement, the person or persons or entity
making such determination shall, to the fullest extent not prohibited by applicable law, presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with
Section 4 of this Agreement, and the Company shall, to the fullest extent not prohibited by applicable law, have the burden of proof and burden of persuasion by clear and convincing evidence to overcome that presumption in connection
with the making by any person, persons or entity of any determination contrary to that presumption. Neither the failure of the Company (including by its directors or Independent Legal Counsel) to have made a determination prior to the commencement
of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or Independent Legal
Counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 

(ii) The termination of any Claim or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea
of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith
and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Claim, that Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful.

 (iii) For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith if
Indemnitee’s action is based on the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee by any of the directors or officers of the Enterprise in the course of their duties, or
on the advice of any legal counsel for the Enterprise or on information or records given or reports 

  
 -9-

 
made to the Enterprise by any independent certified public accountant or by any appraiser or other expert selected with reasonable care by the Enterprise. The provisions of this
Section 4(c) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement. Whether or not the foregoing
provisions of this Section 4(c) are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the
Company. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 
 (iv) The knowledge and/or actions, or failure to act, of any other director, officer, trustee, partner, managing member, fiduciary, agent or employee of the Enterprise shall not be imputed to Indemnitee
for purposes of determining the right to indemnification under this Agreement. 
 (d) Notice to Insurers. If, at
the time of the receipt by the Company of a notice of a Claim pursuant to Section 4(b) hereof, the Company has liability insurance in effect which may cover such Claim, the Company shall give prompt notice of the commencement of such
Claim to the insurers in accordance with the procedures set forth in the respective insurance policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable
as a result of such Claim in accordance with the terms of such policies. 
 (e) Selection of Counsel. In the event
the Company shall be obligated under this Agreement to provide indemnification for or make any Expense Advances with respect to the Expenses of any Claim, the Company, if appropriate, shall be entitled to assume the defense of such Claim with
counsel approved by Indemnitee (which approval shall not be unreasonably withheld) upon the delivery to Indemnitee of written notice of the Company’s election to do so. After delivery of such notice, approval of such counsel by Indemnitee and
the retention of such counsel by the Company, the Company will not be liable to Indemnitee under this Agreement for any fees or expenses of separate counsel subsequently employed by or on behalf of Indemnitee with respect to the same Claim;
provided, however, that (i) Indemnitee shall have the right to employ Indemnitee’s separate counsel in any such Claim at Indemnitee’s expense; and (ii) if (A) the employment of separate counsel by Indemnitee
has been previously authorized by the Company; (B) Indemnitee shall have reasonably concluded that there may be a conflict of interest between the Company and Indemnitee in the conduct of any such defense; or (C) the Company shall not
continue to retain such counsel to defend such Claim, then the fees and expenses of Indemnitee’s separate counsel shall be Expenses for which Indemnitee may receive indemnification or Expense Advances under this Agreement. Subject to the
preceding terms and other terms of this Agreement, the Company shall have the right to conduct such defense as it sees fit in its sole discretion, including the right to settle any Claim against Indemnitee without the consent of Indemnitee, so long
as the terms of such settlement include either: (x) a full release of Indemnitee by the claimant from all liabilities or potential liabilities under such Claim; or (y) in the event such full release is not obtained, the terms of such
settlement do not limit any indemnification right Indemnitee may now, or hereafter, be entitled to under this Agreement, the Certificate of Incorporation, the Bylaws, any other agreement, or by statute, a vote of stockholders or disinterested
directors, the DGCL or otherwise. Notwithstanding the foregoing, the Company shall not settle any Claim in any manner that would impose any Expenses on Indemnitee without Indemnitee’s prior written consent, which consent shall not be
unreasonably withheld.

 5. Additional Indemnification Rights; Nonexclusivity.

 (a) Scope. The Company hereby agrees to indemnify Indemnitee to the fullest extent permitted by applicable law,
notwithstanding that such indemnification is not specifically authorized by the other provisions of this Agreement, the Company’s Certificate of Incorporation, the Bylaws or by statute, any other agreement, a vote of stockholders or
disinterested directors, or otherwise. The rights of indemnification and to receive Expense Advances as provided by this Agreement shall be interpreted independently of, and without reference to, any other such rights to which Indemnitee may be
entitled at any time. In the event of any change after the date of this Agreement in any applicable law, statute or rule which expands the right of a Delaware corporation to indemnify a member of its board of directors or an officer, employee, agent
or fiduciary, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits afforded by such change. In the event of any change in any applicable law, statute or rule which narrows the right of a
Delaware corporation to indemnify a member of its board of directors or an officer, employee, agent or fiduciary, such change, to the extent not otherwise required by such applicable law, statute or rule to be applied to this Agreement, shall have
no effect on this Agreement or the parties’ rights and obligations under this Agreement except as set forth in Section 10(a) hereof. 
 (b) Nonexclusivity. The indemnification rights and the payment of Expense Advances provided by this Agreement shall be cumulative and in addition to any rights to which Indemnitee may be
entitled under the Certificate of Incorporation, the Bylaws, any other agreement, or by statute, a vote of stockholders or disinterested directors, the DGCL, or otherwise. The indemnification rights and the payment of Expense Advances provided under
this Agreement shall continue as to Indemnitee for any action taken or not taken while serving in an indemnified capacity even though subsequent thereto Indemnitee may have ceased to serve in such capacity. 

6. No Duplication of Payments. The Company shall not be liable under this Agreement to make any payment in connection with
any Claim made against Indemnitee to the extent Indemnitee has otherwise actually received payment (under any insurance policy, provision of the Certificate of Incorporation, the Bylaws or otherwise) of the amounts otherwise payable under this
Agreement, except as provided in Section 18 below. 
 7. Partial Indemnification. If Indemnitee is
entitled under any provision of this Agreement to indemnification by the Company for some or a portion of Expenses incurred in connection with any Claim, but not, however, for the total amount thereof, the Company shall nevertheless indemnify
Indemnitee for the portion of such Expenses to which Indemnitee is entitled. 

  
 -11-

 8. Mutual Acknowledgment. Both the Company and Indemnitee acknowledge that, in
certain instances, federal law or applicable public policy may prohibit the Company from indemnifying its directors, officers, employees, agents or fiduciaries under this Agreement or otherwise. Indemnitee understands and acknowledges that the
Company may be required in the future to undertake with the Securities and Exchange Commission to submit the question of indemnification rights to a court in certain circumstances for a determination of the Company’s right under public policy
to indemnify Indemnitee. 
 9. Liability Insurance. To the extent the Company maintains liability
insurance applicable to directors, officers, employees, agents or fiduciaries, Indemnitee shall be covered by such policies in such a manner as to provide Indemnitee the same rights and benefits as are provided to the most favorably insured of the
Company’s directors, if Indemnitee is a director; or of the Company’s officers, if Indemnitee is not a director of the Company but is an officer; or of the Company’s key employees, agents or fiduciaries, if Indemnitee is not an
officer or director but is a key employee, agent or fiduciary. 
 10. Exceptions. Notwithstanding
any other provision of this Agreement: 
 (a) Excluded Action or Omissions. The Company shall not be obligated
pursuant to the terms of this Agreement to indemnify Indemnitee for Expenses resulting from acts, omissions or transactions for which Indemnitee is prohibited from receiving indemnification under this Agreement or applicable law; provided, however,
that notwithstanding any limitation set forth in this Section 10(a) regarding the Company’s obligation to provide indemnification to Indemnitee, Indemnitee shall be entitled under Section 3 to receive Expense Advances
under this Agreement with respect to any such Claim unless and until a court having jurisdiction over the Claim shall have made a final judicial determination (as to which all rights of appeal therefrom have been exhausted or lapsed) that Indemnitee
has engaged in acts, omissions or transactions for which Indemnitee is prohibited from receiving indemnification under this Agreement or applicable law. 
 (b) Claims Initiated by Indemnitee. The Company shall not be obligated pursuant to the terms of this Agreement to indemnify or make Expense Advances to Indemnitee with respect to Claims
initiated or brought voluntarily by Indemnitee and not by way of defense, counterclaim or cross-claim, except (i) with respect to actions or proceedings brought to establish or enforce an indemnification or Expense Advances right under this
Agreement or any other agreement or insurance policy or under the Certificate of Incorporation or the Bylaws relating to Claims for Indemnification Events; (ii) in specific cases if the Board of Directors has approved the initiation or bringing of
such Claim; or (iii) as otherwise required under Section 145 of the DGCL, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification right, Expense Advances or insurance recovery, as the case may be.

  
 -12-

 (c) Claims Under Section 16(b) or Sarbanes-Oxley Act. The Company shall
not be obligated pursuant to the terms of this Agreement to indemnify Indemnitee for expenses and the payment of profits arising from (i) the purchase and sale by Indemnitee of securities in violation of Section 16(b) of the Exchange Act, or
any similar successor statute; or (ii) any reimbursement of the Company by Indemnitee of any bonus or other incentive-based or equity-based compensation or of any profits realized by Indemnitee from the sale of securities of the Company, as required
in each case under the Exchange Act (including any such reimbursements that arise from an accounting restatement of the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or the
payment to the Company of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley Act); provided, however, that notwithstanding any limitation set forth in this
Section 10(c) regarding the Company’s obligation to provide indemnification, Indemnitee shall be entitled under Section 3 to receive Expense Advances with respect to any such Claim unless and until a court having
jurisdiction over the Claim shall have made a final judicial determination (as to which all rights of appeal therefrom have been exhausted or lapsed) that Indemnitee has violated such statute. 

11. Counterparts. This Agreement may be executed in counterparts and by facsimile or electronic transmission, each of which
shall constitute an original and all of which, together, shall constitute one instrument. 
 12. Binding Effect;
Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors, and assigns, including any direct or indirect successor by purchase, merger,
consolidation or otherwise to all or substantially all of the business and/or assets of the Company, spouses, heirs, and personal and legal representatives. The Company shall require and cause any successor (whether direct or indirect by purchase,
merger, consolidation or otherwise) to all, substantially all, or a substantial part, of the business and/or assets of the Company, by written agreement in form and substance satisfactory to Indemnitee, expressly to assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. This Agreement shall continue in effect regardless of whether Indemnitee continues to serve as a director,
officer, employee, agent or fiduciary (as applicable) of the Company or of any other enterprise at the Company’s request. The Company and Indemnitee agree that the Third-Party Indemnitors are express third party beneficiaries of this Agreement.

 13. Remedies of Indemnitee. 
 (a) Subject to Section 2(b)(iii), in the event that (i) a determination is made pursuant to this Agreement that Indemnitee is not entitled to indemnification under this Agreement; (ii) Expense
Advances are not timely made pursuant to Section 3 of this Agreement; (iii) no determination of entitlement to indemnification shall have been made pursuant to the 

  
 -13-

 
provisions of this Agreement within ninety (90) days after receipt by the Company of the request for indemnification; (iv) payment of indemnification is not made pursuant to
Sections 2(a)(i), 2(e) or 7, of this Agreement within ten (10) days after receipt by the Company of a written request therefor; (v) payment of indemnification pursuant to the provisions of this Agreement is not made
within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification by a Reviewing Party; or (vi) the Company or any other person or entity takes or threatens to take any action to declare this Agreement void
or unenforceable, or institutes any litigation or other action or proceeding designed to deny, or to recover from, Indemnitee the benefits provided or intended to be provided to Indemnitee under this Agreement, Indemnitee shall be entitled to an
adjudication by a court regarding Indemnitee’s entitlement to such indemnification or Expense Advances. Alternatively, Indemnitee, at Indemnitee’s option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to
the Commercial Arbitration Rules of the American Arbitration Association. Indemnitee shall commence such proceeding seeking an adjudication or an award in arbitration within 180 days following the date on which Indemnitee first becomes aware or
reasonably should be aware that Indemnitee has the right to commence such proceeding pursuant to this Section 13(a). The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration. 

(b) In the event that a determination shall have been made pursuant to this Agreement that Indemnitee is not entitled to indemnification,
any judicial proceeding or arbitration commenced pursuant to this Section 13 shall be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of that adverse
determination. In any judicial proceeding or arbitration commenced pursuant to this Section 13, the Company shall have the burden of proof and the burden of persuasion by clear and convincing evidence that Indemnitee is not entitled to
indemnification or Expense Advances, as the case may be. 
 (c) If a determination shall have been made pursuant to this
Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 13, absent (i) a misstatement by Indemnitee of a
material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification; or (ii) a determination by a court that such indemnification is prohibited
under applicable law . 
 (d) The Company shall, to the fullest extent not prohibited by applicable law, be precluded from
asserting in any judicial proceeding or arbitration commenced pursuant to this Section 13 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any
such arbitrator that the Company is bound by all the provisions of this Agreement. 
 (e) It is the intent of the Company that,
to the fullest extent permitted by applicable law, Indemnitee not be required to incur legal fees or other Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement by litigation or
otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to Indemnitee under this Agreement. In the event that any action is instituted by Indemnitee under this Agreement or under any
liability insurance policies 

  
 -14-

 
maintained by the Company to enforce or interpret any of the terms hereof or thereof, Indemnitee shall be entitled to be indemnified for all Expenses incurred by Indemnitee with respect to such
action (including without limitation attorneys’ fees), regardless of whether Indemnitee is ultimately successful in such action, unless as a part of such action a court having jurisdiction over such action makes a final judicial determination
(as to which all rights of appeal therefrom have been exhausted or lapsed) that each of the material assertions made by Indemnitee as a basis for such action was not made in good faith or was frivolous; provided, however, that until
such final judicial determination is made, Indemnitee shall be entitled under Section 3 to receive payment of Expense Advances under this Agreement with respect to such action. In the event of an action instituted by or in the name of
the Company under this Agreement to enforce or interpret any of the terms of this Agreement, Indemnitee shall be entitled to be indemnified for all Expenses incurred by Indemnitee in defense of such action (including without limitation costs and
expenses incurred with respect to Indemnitee’s counterclaims and cross-claims made in such action), unless as a part of such action a court having jurisdiction over such action makes a final judicial determination (as to which all rights of
appeal therefrom have been exhausted or lapsed) that each of the material defenses asserted by Indemnitee in such action was made in bad faith or was frivolous; provided, however, that until such final judicial determination is made,
Indemnitee shall be entitled under Section 3 to receive payment of Expense Advances with respect to such action. 

14. Notices. All notices and other communications required or permitted under this Agreement shall be in writing, shall be
effective when given, and shall in any event be deemed to be given (a) three calendar days after deposit with the U.S. Postal Service or other applicable postal service, if delivered by first class mail, postage prepaid; (b) upon delivery,
if delivered by hand; (c) one business day after the business day of deposit with an overnight courier, freight prepaid; or (d) one day after the business day of delivery by facsimile transmission, if deliverable by facsimile transmission,
with a copy by first class mail, postage prepaid, and shall be addressed if to Indemnitee, at Indemnitee’s address as set forth beneath Indemnitee’s signature to this Agreement and if to the Company, at the address of its principal
corporate offices (attention: Chief Financial Officer) or at such other address as such party may designate by ten calendar days’ advance written notice to the other party hereto. 

15. Consent to Jurisdiction. The Company and Indemnitee each hereby irrevocably consent to the jurisdiction of the courts
of the State of Delaware for all purposes in connection with any action or proceeding which arises out of or relates to this Agreement and agree that any action instituted under this Agreement shall be commenced, prosecuted and continued only in the
Court of Chancery of the State of Delaware in and for New Castle County, which shall be the exclusive and only proper forum for adjudicating such a claim. 
 16. Severability. The provisions of this Agreement shall be severable in the event that any of the provisions hereof (including any provision within a single section, paragraph or sentence)
are 

  
 -15-

 
held by a court of competent jurisdiction to be invalid, void or otherwise unenforceable, and the remaining provisions shall remain enforceable to the fullest extent permitted by applicable law.
Furthermore, to the fullest extent possible, the provisions of this Agreement (including without limitation each portion of this Agreement containing any provision held to be invalid, void or otherwise unenforceable, that is not itself invalid, void
or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable. 
 17. Choice of Law. This Agreement, and all rights, remedies, liabilities, powers and duties of the parties to this Agreement, shall be governed by and construed in accordance with the laws
of the State of Delaware without regard to principles of conflicts of laws. 
 18. Primacy of Indemnification;
Subrogation. 
 (a) The Company hereby acknowledges that Indemnitee has or may in the future have certain
indemnification or Expense advancement rights and/or insurance provided by one or more Third-Party Indemnitors. The Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any
obligation of any Third-Party Indemnitors to advance Expenses or to provide indemnification or insurance for the same Expenses incurred by Indemnitee are secondary); (ii) that it shall be required to advance the full amount of Expenses incurred
by Indemnitee and shall be liable for the full amount of all Expenses, to the extent legally permitted and as required or permitted by the Certificate of Incorporation or the Bylaws (or any agreement between the Company and Indemnitee), without
regard to any rights Indemnitee may have against the Third-Party Indemnitors; and (iii) that it irrevocably waives, relinquishes and releases the Third-Party Indemnitors from any and all claims against the Third-Party Indemnitors for contribution,
subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Third-Party Indemnitors on behalf of Indemnitee with respect to any Claim for which Indemnitee has sought
indemnification from the Company shall affect the foregoing and the Third-Party Indemnitors shall have a right to receive from the Company, contribution and/or be subrogated, to the extent of such advancement or payment to all of the rights of
recovery of Indemnitee against the Company. 
 (b) Except as provided in Section 18(a) above, in the event of
payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee from any insurance policy purchased by the Company, who shall execute all documents required and shall do all
acts that may be necessary to secure such rights and to enable the Company effectively to bring suit to enforce such rights. In no event, however, shall the Company or any other person have any right of recovery, through subrogation or otherwise,
against (i) Indemnitee; (ii) any Third-Party Indemnitor; or (iii) any insurance policy purchased or maintained by Indemnitee or any Third-Party Indemnitor. 

  
 -16-

 19. Amendment and Termination. No amendment, modification, termination or
cancellation of this Agreement shall be effective unless it is in writing signed by both the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed to be or shall constitute a waiver of any other provisions hereof
(whether or not similar), nor shall such waiver constitute a continuing waiver. 
 20. Integration and Entire
Agreement. This Agreement sets forth the entire understanding between the parties hereto and supersedes and merges all previous written and oral negotiations, commitments, understandings and agreements relating to the subject matter hereof
between the parties hereto; provided, however, that this Agreement is a supplement to and in furtherance of the Certificate of Incorporation, the Bylaws, any directors and officers insurance maintained by the Company and applicable law, and shall
not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder. 
 21. No
Construction as Employment Agreement. Nothing contained in this Agreement shall be construed as giving Indemnitee any right to employment by the Company or any of its subsidiaries or affiliated entities. 

22. Additional Acts. If, for the validation of any of the provisions in this Agreement, any act, resolution, approval or
other procedure is required, the Company undertakes to cause such act, resolution, approval or other procedure to be effected or adopted in a manner that will enable the Company to fulfill its obligations under this Agreement.

 - 3 -

 
Shares which were subject thereto shall become available for future grant or sale under the Plan (unless the Plan has terminated). However, Shares that have actually been issued under the Plan,

such Shares shall become available for future grant under the Plan. 
 4. Administration of the Plan.

 (a) Administrator. The Plan shall be administered by the Board or a Committee appointed by the Board, which
Committee shall be constituted to comply with Applicable Laws. 
 (b) Powers of the Administrator. Subject
to the provisions of the Plan and, in the case of a Committee, the specific duties delegated by the Board to such Committee, and subject to the approval of any relevant authorities, the Administrator shall have the authority in its discretion:

 (i) to determine the Fair Market Value; 
 (ii) to select the Service Providers to whom Options and Stock Purchase Rights may from time to time be granted hereunder; 
 (iii) to determine the number of Shares to be covered by each award granted hereunder; 
 (iv) to approve forms of agreement for use under the Plan; 
 (v) to determine the
terms and conditions, of any Option or Stock Purchase Right granted hereunder. Such terms and conditions include, but are not limited to, the exercise price, the time or times when Options or Stock Purchase Rights may be exercised (which may be
based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or limitation regarding any Option or Stock Purchase Rights or the Common Stock relating thereto, based in each case on such factors
as the Administrator, in its sole discretion, shall determine;

obligations by electing to have the Company withhold from the Shares to be issued upon exercise of an Option or Stock Purchase Right that number of Shares having a Fair Market Value equal to the minimum

  
 - 4 -

 
amount required to be withheld. The Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined. All elections by
Optionees to have Shares withheld for this purpose shall be made in such form and under such conditions as the Administrator may deem necessary or advisable; and 
 (ix) to construe and interpret the terms of the Plan and Options and Stock Purchase Rights granted pursuant to the Plan. 
 (c) Effect of Administrator’s Decision. All decisions, determinations and interpretations of the Administrator shall be final and binding on all Optionees. 

5. Eligibility. Nonstatutory Stock Options and Stock Purchase Rights may be granted to Service Providers. Incentive Stock Options
may be granted only to Employees. 
 6. Limitations. 

(a) Incentive Stock Option Limit. Each Option shall be designated in the Option Agreement as either an Incentive Stock Option or a
Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Optionee during any
calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 6(a), Incentive Stock Options shall be taken into account in
the order in which they were granted. The Fair Market Value of the Shares shall be determined as of the time the Option with respect to such Shares is granted. 
 (b) At-Will Employment. Neither the Plan nor any Option or Stock Purchase Right shall confer upon any Optionee any right with respect to continuing the Optionee’s relationship as a Service
Provider with the Company, nor shall it interfere in any way with the Optionee’s right or the Company’s right to terminate such relationship at any time, with or without cause, and with or without notice. 

7. Term of Plan. Subject to stockholder approval in accordance with Section 19, the Plan shall become effective
upon its adoption by the Board. Unless sooner terminated under Section 15, it shall continue in effect for a term of ten (10) years from the later of (i) the effective date of the Plan or (ii) the date of the most recent Board
approval of an increase in the number of Shares reserved for issuance under the Plan. 
 8. Term of Option. The term of
each Option shall be stated in the Option Agreement; provided, however, that the term shall be no more than ten (10) years from the date of grant thereof. In the case of an Incentive Stock Option granted to an Optionee who, at the time
the Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Option shall be five (5) years from the date of grant or
such shorter term as may be provided in the Option Agreement. 

  
 - 5 -

 9. Option Exercise Price and Consideration. 

(a) Exercise Price. The per share exercise price for the Shares to be issued upon exercise of an Option shall be such price as is
determined by the Administrator, but shall be subject to the following: 
 (i) In the case of an Incentive Stock Option

 (A) granted to an Employee who, at the time of grant of such Option, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant. 

(B) granted to any other Employee, the per Share exercise price shall be no less than 100% of the Fair Market Value per Share on the
date of grant. 
 (ii) In the case of a Nonstatutory Stock Option 

(A) granted to any other Service Provider, the per Share exercise price shall be determined by the Administrator. 

(iii) Notwithstanding the foregoing, Options may be granted with a per Share exercise price other than as required above pursuant to a
merger or other corporate transaction. 
 (b) Forms of Consideration. The consideration to be paid for the Shares to be
issued upon exercise of an Option, including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option, shall be determined at the time of grant). Such consideration may consist of, without
limitation, (1) cash, (2) check, (3) promissory note, (4) other Shares, provided Shares acquired directly from the Company (x) have been owned by the Optionee for more than six (6) months on the date of surrender, and
(y) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which such Option shall be exercised, (5) consideration received by the Company under a cashless exercise program implemented
by the Company in connection with the Plan, or (6) any combination of the foregoing methods of payment. In making its determination as to the type of consideration to accept, the Administrator shall consider if acceptance of such consideration
may be reasonably expected to benefit the Company.

 10. Exercise of Option. 

(a) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder shall be exercisable according to the
terms hereof at such times and under such conditions as determined by the Administrator and set forth in the Option Agreement. An Option may not be exercised for a fraction of a Share. 

(i) An Option shall be deemed exercised when the Company receives: (i) written or electronic notice of exercise (in accordance with
the Option Agreement) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised. Full payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued upon exercise of an Option shall be issued in the name of the Optionee or, if requested by the Optionee, in the name of the Optionee and the Optionee’s spouse.
Until the Shares are issued (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 Shares, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date
is prior to the date the Shares are issued, except as provided in Section 13. 
 (ii) Exercise of an Option in any manner
shall result in a decrease in the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. 

(b) Termination of Relationship as a Service Provider. If an Optionee ceases to be a Service Provider other than upon such
Optionee’s death or Disability, such Optionee may exercise such Optionee’s Option within such period of time as is specified in the Option Agreement to the extent that the Option is vested on the date of termination (but in no event later
than the expiration of the term of the Option as set forth in the Option Agreement). In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for three (3) months following the Optionee’s termination.
If, on the date of termination, the Optionee is not vested as to such Optionee’s entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise such
Optionee’s Option within the time specified by the Administrator, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan. 
 (c) Disability of Optionee. If an Optionee ceases to be a Service Provider as a result of the Optionee’s Disability, such Optionee may exercise such Optionee’s Option within such period
of time as is specified in the Option Agreement to the extent the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement). In the absence of a specified
time in the Option Agreement, the Option shall remain exercisable for twelve (12) months following the Optionee’s termination. If, on the date of termination, the Optionee is not vested as to such Optionee’s entire Option, the Shares
covered by 

  
 - 7 -

 
the unvested portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise such Optionee’s Option within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan. 
 (d) Death of Optionee. If an
Optionee dies while a Service Provider, the Option may be exercised within such period of time as is specified in the Option Agreement to the extent that the Option is vested on the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Option Agreement) by the Optionee’s designated beneficiary, provided such beneficiary has been designated prior to such Optionee’s death in a form acceptable to the Administrator. If no such
beneficiary has been designated by the Optionee, then such Option may be exercised by the personal representative of the Optionee’s estate or by the person(s) to whom the Option is transferred pursuant to the Optionee’s will or in
accordance with the laws of descent and distribution. In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for twelve (12) months following the Optionee’s death. If, at the time of death, the
Optionee is not vested as to the entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If the Option is not so exercised within the time specified herein, the Option shall terminate, and the Shares covered
by such Option shall revert to the Plan. 
 (e) Leaves of Absence. 

(i) Unless the Administrator provides otherwise, vesting of Options granted hereunder shall be suspended during any unpaid leave of
absence. 
 (ii) A Service Provider shall not cease to be an Employee in the case of (A) any leave of absence approved by
the Company or (B) transfers between locations of the Company or between the Company, its Parent, any Subsidiary, or any successor. 
 (iii) For purposes of Incentive Stock Options, no such leave may exceed ninety (90) days, unless reemployment upon expiration of such leave is guaranteed by statute or contract. If reemployment upon
expiration of a leave of absence approved by the Company is not so guaranteed, then three (3) months following the 91st day of such leave, any Incentive Stock Option held by the Optionee shall cease to be treated as an Incentive Stock Option
and shall be treated for tax purposes as a Nonstatutory Stock Option. 
 11. Stock Purchase Rights. 

(a) Rights to Purchase. Stock Purchase Rights may be issued either alone, in addition to, or in tandem with other awards granted
under the Plan and/or cash awards made outside of the Plan. After the Administrator determines that it will offer Stock Purchase Rights under the Plan, it shall advise the offeree in writing or electronically of the terms, conditions and
restrictions related to the offer, including the number of Shares that such person shall be entitled to purchase, the price to be paid, and the time within which such person must accept such offer. The offer shall be accepted by execution of a
Restricted Stock Purchase Agreement in the form determined by the Administrator. 

  
 - 8 -

 (b) Repurchase Option. Unless the Administrator determines otherwise, the Restricted
Stock Purchase Agreement shall grant the Company a repurchase option exercisable within 90 days of the voluntary or involuntary termination of the purchaser’s service with the Company for any reason (including death or disability). The purchase
price for Shares repurchased pursuant to the Restricted Stock Purchase Agreement shall be the original price paid by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the Company. The repurchase option shall lapse
at such rate as the Administrator may determine. 
 (c) Other Provisions. The Restricted Stock Purchase Agreement shall
contain such other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. 
 (d) Rights as a Stockholder. Once the Stock Purchase Right is exercised, the purchaser shall have rights equivalent to those of a stockholder and shall be a stockholder when his or her purchase is
entered upon the records of the duly authorized transfer agent of the Company. No adjustment shall be made for a dividend or other right for which the record date is prior to the date the Stock Purchase Right is exercised, except as provided in
Section 13 of the Plan. 
 12. Limited Transferability of Options. Unless determined otherwise by the
Administrator, Options and Stock Purchase Rights may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent and distribution and may be exercised, during the lifetime of
the Optionee, only by the Optionee. 
 13. Adjustments; Dissolution or Liquidation; Merger or Change of Control.

 (a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Shares, other
securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the
corporate structure of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, may (in its sole discretion) adjust
the number and class of Shares that may be delivered under the Plan and/or the number, class, and price of Shares covered by each outstanding Option or Stock Purchase Right. 
 (b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator shall notify each Optionee as soon as practicable prior to the effective
date of such proposed transaction. To the extent it has not been previously exercised, an Option will terminate immediately prior to the consummation of such proposed action. 

  
 - 9 -

 (c) Merger or Change of Control. 

(i) In the event of (x) a merger of the Company with or into another entity (other than a merger effected primarily for the purpose
of changing the Company’s state of incorporation) or (y) any other Change of Control, each outstanding Option and Stock Purchase Right, to the extent vested as of the transaction date, shall be (i) assumed, (ii) an equivalent
option or right substituted by the successor entity (or a Parent or Subsidiary of the successor entity) or (iii) cancelled in exchange for a payment to the Optionee with respect to each Share subject to the portion of the Option or Stock
Purchase that is vested as of the transaction date equal to the excess of (A) the value, as determined by the Board in its absolute discretion, of the property (including cash) received by the holder of a share of Stock as a result of the
transaction, over (B) the per-Share exercise price of the Option or the per-Share purchase price of such Stock Purchase Right (such excess, the “Spread”). In the event of a payment described in Clause (iii) of the preceding
sentence, such payment shall be made in the form of cash, cash equivalents, or securities of the surviving corporation or its parent having a value equal to the Spread; in addition, any escrow, holdback, earn-out or similar provisions in the
transaction agreement may apply to such payment to the same extent and in the same manner as such provisions apply to the holders of Stock. If the Spread applicable to an Option is zero or a negative number, then the Option may be cancelled
without making a payment to the Optionee. In the event that the successor entity (or a Parent or Subsidiary of the successor entity) refuses to assume, substitute or cancel an Option or Stock Purchase Right as described above, such Option or Stock
Purchase shall terminate as of the closing date of such transaction without the payment of any consideration to the Optionee; provided that the Administrator shall notify the Optionee in writing or electronically that the Option or Stock Purchase
Right shall be exercisable for a period of time as determined by the Administrator, and the Option or Stock Purchase Right shall terminate upon expiration of such period. For the purposes of this paragraph, an Option or Stock Purchase Right shall be
considered assumed if, following the merger or Change of Control, the option or right confers the right to purchase or receive, for each Share of Optioned Stock subject to such Option or Stock Purchase Right immediately prior to the merger or Change
of Control, the consideration (whether stock, cash, or other securities or property) received in the merger or Change of Control by holders of Common Stock for each Share held on the effective date of the merger or Change of Control (and if holders
were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the merger or Change of Control is not solely common
stock of the successor entity or its Parent, the Administrator may, with the consent of the successor entity, provide for the consideration to be received upon the exercise of the Option or Stock Purchase Right, for each Share of Optioned Stock
subject to the Option or Stock Purchase Right, to be solely common stock of the successor entity or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the merger or Change of Control.

 (ii) In the event of (x) a merger of the Company with or into another entity (other than a merger effected primarily
for the purpose of changing the Company’s state of incorporation) or (y) any other Change of Control, each outstanding Option and Stock Purchase 

  
 - 10 -

 
Right, to the extent unvested as of the transaction date, may, at the discretion of the Board, fully vest and become exercisable as to all of the Optioned Stock, including Shares as to which such
Option or Stock Purchase Right would not otherwise be vested or exercisable, be assumed or an equivalent option or right substituted as provided in Section 13(c)(1) above, be canceled without the payment of any consideration, or be treated in
any other manner permitted by applicable law. 
 14. Time of Granting Options and Stock Purchase Rights.
The date of grant of an Option or Stock Purchase Right shall, for all purposes, be the date on which the Administrator makes the determination granting such Option or Stock Purchase Right, or such later date as is determined by the Administrator.
Notice of the determination shall be given to each Service Provider to whom an Option or Stock Purchase Right is so granted within a reasonable time after the date of such grant. 

15. Amendment and Termination of the Plan. 

(a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan. 

(b) Stockholder Approval. The Board shall obtain stockholder approval of any Plan amendment to the extent necessary and desirable
to comply with Applicable Laws. 
 (c) Effect of Amendment or Termination. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee, unless mutually agreed otherwise between the Optionee and the Administrator, which agreement must be in writing and signed by the Optionee and the Company. Termination of
the Plan shall not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Options granted under the Plan prior to the date of such termination. 

16. Conditions Upon Issuance of Shares. 

(a) Legal Compliance. Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance. 
 (b) Investment Representations. As a condition to the exercise of an Option, the Administrator may require the person exercising such Option to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required. 

17. Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction,
which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such
requisite authority shall not have been obtained. 

  
 - 11 -

 18. Reservation of Shares. The Company, during the term of this Plan, shall
at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. 

19. Stockholder Approval. The Plan shall be subject to approval by the stockholders of the Company within twelve (12) months
after the date the Plan is adopted. Such stockholder approval shall be obtained in the degree and manner required under Applicable Laws.

or substitution of Indian Options in the same manner as the other Options then the Administrator, in its discretion, may provide for the termination of the Indian Options upon the consummation of the transaction or provide for the assumption or
substitution of the Indian Options in a different manner than the assumption or substitution of the other Options.
