4. Administration of the Plan. 

(a) Administrator. The Plan will be administered by the Board or a Committee appointed by the Board, which Committee will be

hereunder; 
 (iii) to determine the number of Shares or Restricted Stock Units 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 Award granted hereunder. Such terms and conditions include, but are not limited to, the
exercise price, the time or times when Awards may be exercised (which may be based on performance criteria), any vesting, vesting acceleration or waiver of forfeiture restrictions, and any restriction or limitation regarding any Award or any Common
Stock relating thereto, based in each case on such factors as the Administrator, in its sole discretion, will determine;

 (c) Effect of Administrator’s Decision. All decisions,
determinations and interpretations of the Administrator will be final and binding on all Participants. 
 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. Stock Options. 

(a) Term of Option. The term of each Award will be stated in the Award Agreement; provided, however, that the term will be no more
than ten (10) years from the date of grant thereof. In the case of an Incentive Stock Option granted to an Participant 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 will be five (5) years from the date of grant or such shorter term as may be provided in the Award Agreement. 

(b) Option Exercise Price and Consideration. 

(i) 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, but will be subject to the following: 
 (A) 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 will be no less than 110% of the Fair Market Value per Share on the date of grant. 

 

 4 








 b) granted to any other Employee, the per Share exercise price will be no less than 100% of
the Fair Market Value per Share on the date of grant. 
 (B) In the case of a Nonstatutory Stock Option, the per Share exercise
price will be determined by the Administrator. 
 (C) Notwithstanding the foregoing, Incentive Stock Options may be granted
with a per Share exercise price other than as required above in accordance with and pursuant to a transaction described in Section 424 of the Code. 

(ii) Forms of Consideration. The consideration to be paid for the Shares to be issued upon exercise of an Option, including the
method of payment, will be determined by the Administrator (and, in the case of an Incentive Stock Option, will 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 Participant, and not subject to a substantial risk of forfeiture, for more than six 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 will 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 will consider if acceptance of such
consideration may be reasonably expected to benefit the Company. 
 (c) Exercise of Option. 

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

An Option will be deemed exercised when the Company receives (i) written or electronic notice of exercise (in accordance with the
Award Agreement) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised, together with any applicable withholding taxes. Full payment may consist of any consideration
and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant, in the name of the
Participant and his or her 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 will exist with respect to the Shares, notwithstanding the exercise of the Option. The Company will 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 11 of the Plan. 

Exercise of an Option in any manner will 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. 
 (ii) Termination of
Relationship as a Service Provider. If a Participant ceases to be a Service Provider, such Participant may exercise his or her Option within such period of time as is specified in the Award 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 Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for three
(3) months following the Participant’s termination. Unless the Administrator provides otherwise, if on the date of termination the Participant is not vested as to his or 

 

 5 








 
her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If, after termination, the Participant does not exercise his or her Option within the time
specified by the Administrator, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

(iii) Disability of Participant. If a Participant ceases to be a Service Provider as a result of the Participant’s
Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award 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 Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following the Participant’s termination. Unless the Administrator provides
otherwise, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If, after termination, the Participant does not exercise his or
her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

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

(d) Incentive Stock Option Limit. Each Option will be designated in the Award 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 Participant during any
calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such Options will be treated as Nonstatutory Stock Options. For purposes of this Section 6(d), Incentive Stock Options will be taken into account in
the order in which they were granted. The Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted. 

7. 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 will advise the offeree in writing of the terms, conditions and restrictions related to the
offer, including the number of Shares that such person will be entitled to purchase, vesting, the price to be paid, and the time within which such person must accept such offer. 

(b) Repurchase Option. Unless the Administrator determines otherwise, the Award Agreement will grant the Company a repurchase
option exercisable within ninety (90) days of the voluntary or involuntary termination of the purchaser’s service with the Company for any reason (including death or disability). Unless the Administrator provides otherwise, the purchase
price for Shares repurchased pursuant to the Award Agreement will 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 will lapse at such rate as the
Administrator may determine. 
 (c) Other Provisions. The Award Agreement will 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 will have rights equivalent to those of a stockholder and will be a stockholder when his or her purchase is entered upon the records of the duly authorized transfer agent
of the Company. No adjustment will 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 11 of the Plan. 

 

 6 








 8. Restricted Stock and Restricted Stock Units. 

(a) Grant. Shares of Restricted Stock and/or Restricted Stock Units may be granted 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 Restricted Stock and/or Restricted Stock Units under the Plan, it will advise the offeree in writing of the terms,
conditions and restrictions related to the offer, including the applicable number of Shares of Restricted Stock or the number of Restricted Stock Units, as the case may be, that such person will be entitled to receive, the vesting terms, the price
to be paid if any, and the time within which such person must accept such offer. 
 (b) Repurchase Option. Unless the
Administrator determines otherwise, the Company will have an option to repurchase vested Restricted Stock and/or Restricted Stock Units within ninety (90) days of the voluntary or involuntary termination of the holder’s service with the
Company for any reason (including death or disability) at fair market value as determined in good faith by the Administrator. To the extent that the holder purchased Shares granted under a Restricted Stock Award and any such Shares remain non-vested
at the time the grantee ceases to be a Service Provider, the cessation of Service Provider status shall cause an immediate sale of such non-vested Shares to the Company at the original price per Share paid by the grantee. 

(c) Other Provisions. The Award Agreement will 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 shares of
Restricted Stock have vested, the holder will be a stockholder and his or her ownership will entered upon the records of the duly authorized transfer agent of the Company. No adjustment will be made for a dividend or other right for which the record
date is prior to the date such Restricted Stock is vested, except as provided in Section 11 of the Plan. Owners of Restricted Stock Units shall have no rights as stockholders by virtue of such ownership. 

9. Tax Withholding. Prior to the delivery of any Shares pursuant to an Award (or exercise thereof), the Company will have the
power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state, local, foreign or other taxes (including the Participant’s FICA obligation) required to be withheld
with respect to such Award (or exercise thereof). The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, will determine in what manner it will allow a Participant to satisfy such tax
withholding obligation. 
 10. Transferability of Awards. Unless determined otherwise by the Administrator, Awards 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. 

11. Leaves of Absence. 

(a) Unless the Administrator provides otherwise, vesting of Awards granted hereunder will be suspended during any unpaid leave of
absence. 
 (b) A Service Provider will 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. 

(c) 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 Participant will cease to be treated as an Incentive Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option. 
  

 7 








 12. Adjustments; Dissolution or Liquidation; Merger or Change in 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 Award. 

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator will
notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will terminate immediately prior to the consummation of such proposed action.

 (c) Merger or Change in Control. In the event of a merger of the Company with or into another corporation, or a
Change in Control, each outstanding Award, and, if applicable, Shares of Restricted Stock acquired pursuant thereto, will be assumed or an equivalent award substituted by the successor corporation or a Parent or Subsidiary of the successor
corporation. In the event that the successor corporation in a merger or Change in Control refuses to assume or substitute for an Award and, if applicable, Shares of Restricted Stock acquired pursuant thereto, then the Participant will fully vest in
and have the right to exercise the Award as to all of the Shares subject thereto, including Shares as to which it would not otherwise be vested or exercisable, and all restrictions on Restricted Stock will lapse. If an Award is not assumed or
substituted in the event of a merger or Change in Control, the Administrator will notify the Participant in writing or electronically that the Award will be exercisable for a period of time as determined by the Administrator, and the Award will
terminate upon expiration of such period for no consideration, unless otherwise determined by the Administrator. 
 For the
purposes of this subsection (c), the Award will be considered assumed if, following the merger or Change in Control, the award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the merger or Change in
Control, the consideration (whether stock, cash, or other securities or property) received in the merger or Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (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 in Control is not solely common stock of the successor
corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Award, for each Share subject to the Award, to be solely common stock of the
successor corporation or its Parent equal in fair market value to the per Share consideration received by holders of Common Stock in the merger or Change in Control. 

13. Time of Granting Awards. The date of grant of an Award will, for all purposes, be the date on which the Administrator makes
the determination granting such Award, or such later date as is determined by the Administrator. Notice of the determination will be given to each Service Provider to whom an Award is so granted within a reasonable time after the date of such grant.

 14. No Effect on Employment or Service. Neither the Plan nor any Award will confer upon any Participant any right with
respect to continuing the Participant’s relationship as a Service Provider with the Company, nor will it interfere in any way with his or her right or the Company’s right to terminate such relationship at any time, with or without cause,
and with or without notice. 
 15. Conditions Upon Issuance of Shares. 

(a) Legal Compliance. Shares will not be issued pursuant to the exercise of an Award unless the exercise of such Award and the
issuance and delivery of such Shares will comply with Applicable Laws and will be further subject to the approval of counsel for the Company with respect to such compliance. 

 

 8 








 (b) Investment Representations. As a condition to the exercise of an Award, the
Administrator may require the person exercising such Award 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. 
 16. 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, will relieve the Company of
any liability in respect of the failure to issue or sell such Shares as to which such requisite authority will not have been obtained. 

17. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of
Shares as will be sufficient to satisfy the requirements of the Plan. 
 18. Stockholder Approval. The Plan will be
subject to approval by the stockholders of the Company within twelve (12) months after the date the Plan is adopted. Such stockholder approval will be obtained in the degree and manner required under Applicable Laws. 

19. Term of Plan. Subject to stockholder approval in accordance with Section 18, the Plan will become effective upon its
adoption by the Board. Unless sooner terminated under Section 20, it will continue in effect for a term of ten (10) years from the later of (i) the effective date of the Plan, or (ii) the earlier of the most recent Board or
stockholder approval of an increase in the number of Shares reserved for issuance under the Plan. 
 20. 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 will 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 will materially impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant
and the Company. Termination of the Plan will not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination.
