 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. 

  
 - 5 - 








 (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. 

  
 - 6 - 








 (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 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.


  
 - 7 - 








 (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. 
 (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.  

  
 - 8 - 








 (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. 
 (c) Merger or Change of Control.    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 shall be assumed or an
equivalent option or right substituted by the successor entity (or a Parent or Subsidiary of the successor entity). In the event that the successor entity (or a Parent or Subsidiary of the successor entity) refuses to assume or substitute for an
Option or Stock Purchase Right, the Optionee shall fully vest in and have the right to exercise such Option or Stock Purchase Right 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. If an Option or Stock Purchase Right becomes fully vested and exercisable in lieu of assumption or substitution in the event of a merger or Change of Control, the Administrator shall notify the Optionee in writing or
electronically that the Option or Stock Purchase Right shall be fully 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. 
 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 

  
 - 9 - 








 
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. 
 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.

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. 
 3.

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 Administrator will determine the fair market value of the Shares based upon the Company’s

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.

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.

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.

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
