 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

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.

 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.

Purpose. The purpose of this Appendix B is to establish certain rules applicable to Shares which may be granted under the Plan from time to time to Employees of the Indian Subsidiary, who are residents of the Republic of India, in compliance
with the exchange control, securities and other Applicable Laws currently in force in India. Except as otherwise provided by this Appendix B, all Shares granted pursuant to this Appendix B shall be governed by the terms of the Plan. In the event of
a conflict between the provisions of the Plan and the provisions of this Appendix B, the provisions of this Appendix B shall prevail.

exceed 11,287,500 (subject to adjustment as provided in Section 13 of the Plan). In determining which Employees may be granted Options and for determining the quantum of Options to be granted, the Administrator will take into account whether
Options will provide additional incentive to Employees, whether such Options will promote the success of the Company’s business, the potential for future contribution to the Company and the Indian Subsidiary, integrity, number of employment
years and any other factor(s) as deemed appropriate by the Administrator. 
 5. Basis of Valuation of the Shares. The

not available at the time of such determination), current book value per Share, the price at which Shares have previously been issued by the Company, the liquidation rights and other preferences to which the holders of those Shares are entitled, the
lack of marketability of the Shares, the start-up nature of the Company and other factors that the Administrator considers appropriate in good faith. 
 6. Exercise Price. The per share exercise price for the Shares to be issued upon exercise of an Option will be such price as is determined by the Administrator in a manner consistent with

Administrator, Options may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or the laws of descent and distribution, and may be exercised during the lifetime of the Participant, only by the
Participant. If the Administrator in its sole discretion makes an Option transferable, such Option may only be transferred pursuant to the provisions of Section 12 of the Plan. 

8. Restrictions on Shares. The Administrator may place restrictions on the transferability of Shares acquired pursuant to an
Option as it deems appropriate in its sole discretion, including, without limitation, (i) rights to repurchase upon termination as an Employee, (ii) rights of first refusal, and (iii) market lock-up provisions.

transaction described in Section 13(c) of the Plan intends to assume or substitute each outstanding Option and the rules and regulations governing Options granted to Employees in India (the “Indian Options”) do not permit assumption
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. 
 10.
Stockholder Approval. The Plan (and therefore the authority of the Administrator to adopt this Appendix B) will be subject to approval by the stockholders of the Company as provided in Section 19 of the Plan. 

11. Currency Exchange Rates. Except as otherwise determined by the Administrator, all monetary values under this Appendix B
including, without limitation, the Fair Market Value per share of Common Stock and the Exercise Price shall be stated in US Dollars. Any changes or fluctuations in the exchange rate at which amounts paid by an Optionee in currencies other than US
Dollars are converted into US Dollars or amounts paid to an Optionee in US Dollars are converted into currencies other than US Dollars shall be borne solely by the Optionee.

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

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

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.

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.

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.

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

	SECURITY	  	 	:	  	  	COMMON STOCK
			
	AMOUNT	  	 	:	  	  	
			
	DATE	  	 	:	  	  	

 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.

 R E C I T A L S 
 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. 

  
 - 2 -

 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.

 IN WITNESS WHEREOF, this Agreement is deemed made as of the date first set forth above.

 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 

  
 - 2 -

 
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.
