 4. Administration of the Plan.

 (a) General. The Plan shall be administered by the Board or a Committee, or a combination thereof, as
determined by the Board. The Plan may be administered by different administrative bodies with respect to different classes of Participants and, if permitted by the Applicable Laws, the Board may authorize one or more officers to make awards under
the Plan.

administering the Plan in accordance with the requirements of Rule 16b-3 or Section 162(m) of the Code, to the extent permitted or required by such provisions. The Committee shall in all events conform to any requirements of the Applicable
Laws.

terms and conditions include but are not limited to the exercise or purchase price, the time or times when awards may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, any pro
rata adjustment to vesting as a result of a Participant’s transitioning from full- to part-time service (or vice versa), and any restriction or limitation regarding any Option, Optioned Stock, Stock Purchase Right, Restricted Stock or
Restricted Stock Unit Award, based in each case on such factors as the Administrator, in its sole discretion, shall determine; 

(vii) to determine whether and under what circumstances an Option may be settled in cash under Section 9(c) instead of Common
Stock; 
 (viii) to implement an Option Exchange Program on such terms and conditions as the Administrator in its discretion
deems appropriate, provided that no amendment or adjustment to an Option that would materially and adversely affect the rights of any Optionee shall be made without the prior written consent of the Optionee; 

(ix) to adjust the vesting of an Option held by an Employee or Consultant as a result of a change in the terms or conditions under which
such person is providing services to the Company; 
 (x) to construe and interpret the terms of the Plan and Stock Awards
granted under the Plan, which constructions, interpretations and decisions shall be final and binding on all Participants; and 

(xi) in order to fulfill the purposes of the Plan and without amending the Plan, to modify grants of Stock Awards to Participants who
are foreign nationals or employed outside of the United States in order to recognize differences in local law, tax policies or customs. 
 5. Eligibility. 
 (a) Recipients of Grants.
Nonstatutory Stock Options and Stock Purchase Rights and Restricted Stock Unit Awards may be granted to Employees and Consultants. Incentive Stock Options may be granted only to Employees, provided that Employees of Affiliates shall not be eligible
to receive Incentive Stock Options. 
 (b) Type of Option. Each Option shall be designated in the Option Agreement
as either an Incentive Stock Option or a Nonstatutory Stock Option. 
 (c) ISO $100,000 Limitation.

any calendar year (under all plans of the Company or any Parent or Subsidiary) exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock Options. For purposes of 

  
 -6-









 
this Section 5(c), Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of the Shares subject to an Incentive Stock Option
shall be determined as of the date of the grant of such Option. 
 (d) No Employment Rights. The Plan shall not
confer upon any Participant any right with respect to continuation of an employment or consulting relationship with the Company, nor shall it interfere in any way with such Participant’s right or the Company’s right to terminate the
employment or consulting relationship at any time for any reason. 
 6. Term of Plan. The Plan shall become
effective upon its adoption by the Board of Directors. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 16 of the Plan. 

7. Term of Option. The term of each Option shall be the term stated in the Option Agreement; provided that the term shall
be no more than ten years from the date of grant thereof or such shorter term as may be provided in the Option Agreement and provided further that, in the case of an Incentive Stock Option granted to a person who at the time of such grant is a
Ten Percent Holder, the term of the Option shall be five years from the date of grant thereof or such shorter term as may be provided in the Option Agreement. 
 8. Option Exercise Price and Consideration. 
 (a) Exercise
Price. The per Share exercise price for the Shares to be issued pursuant to exercise of an Option shall be such price as is determined by the Administrator and set forth in the Option Agreement, 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 is a Ten Percent Holder, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant; or 

(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 on any date on which the Common Stock is not a Listed Security to a person who is at the time of grant is a Ten Percent
Holder, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant if required by the Applicable Laws and, if not so required, shall be such price as is determined by the Administrator;

 (B) granted on any date on which the Common Stock is not a Listed Security to any other eligible person, the per Share
exercise price shall be no less than 85% of the Fair Market Value per Share on the date of grant if required by the Applicable Laws and, if not so required, shall be such price as is determined by the Administrator; or 

  
 -7-









 (C) granted on any date on which the Common Stock is a Listed Security to any eligible
person, the per share Exercise Price shall be such price as determined by the Administrator provided that if such eligible person is, at the time of the grant of such Option, a Named Executive of the Company, the per share Exercise Price shall be no
less than 100% of the Fair Market Value on the date of grant if such Option is intended to qualify as performance-based compensation under Section 162(m) of the Code. 
 (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) Permissible 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) and may consist entirely of (1) cash; (2) check; (3) subject to any
requirements of the Applicable Laws, delivery of Optionee’s promissory note having such recourse, interest, security and redemption provisions as the Administrator determines to be appropriate; (4) cancellation of indebtedness;
(5) other Shares that have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which the Option is exercised, provided that in the case of Shares acquired, directly or indirectly, from the
Company, such Shares must have been owned by the Optionee for such period as may be required to avoid the Company’s incurring an adverse accounting charge; (6) if, as of the date of exercise of an Option the Company then is permitting
employees to engage in a “same-day sale” cashless brokered exercise program involving one or more brokers, through such a program that complies with the Applicable Laws (including without limitation the requirements of Regulation T and
other applicable regulations promulgated by the Federal Reserve Board) and that ensures prompt delivery to the Company of the amount required to pay the exercise price and any applicable withholding taxes; (7) any combination of the foregoing
methods of payment; or (8) such other consideration and method of payment as determined by the Administrator and to the extent permitted under Applicable Laws. 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 and the Administrator may, in its sole discretion, refuse to accept a particular form of consideration at the time of any Option
exercise. 
 9. Exercise of Option. 
 (a) General. 
 (i) Exercisability. Any Option granted
hereunder shall be exercisable at such times and under such conditions as determined by the Administrator, consistent with the term of the Plan and reflected in the Option Agreement, including vesting requirements and/or performance criteria with
respect to the Company and/or the Optionee. 

  
 -8-









 (ii) Leave of Absence. The Administrator shall have the discretion to
determine whether and to what extent the vesting of Options shall be tolled during any unpaid leave of absence; provided, however, that in the absence of such determination, vesting of Options shall be tolled during any such unpaid leave (unless
otherwise required by the Applicable Laws). In the event of military leave, vesting shall toll during any unpaid portion of such leave, provided that, upon a Participant’s returning from military leave (under conditions that would entitle him
or her to protection upon such return under the Uniform Services Employment and Reemployment Rights Act), he or she shall be given vesting credit with respect to Options to the same extent as would have applied had the Participant continued to
provide services to the Company throughout the leave on the same terms as he or she was providing services immediately prior to such leave. 
 (iii) Minimum Exercise Requirements. An Option may not be exercised for a fraction of a Share. The Administrator may require that an Option be exercised as to a minimum number of Shares,
provided that such requirement shall not prevent an Optionee from exercising the full number of Shares as to which the Option is then exercisable. 
 (iv) Procedures for and Results of Exercise. An Option shall be deemed exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option
by the person entitled to exercise the Option and the Company has received full payment for the Shares with respect to which the Option is exercised. Full payment may, as authorized by the Administrator, consist of any consideration and method of
payment allowable under Section 8(b) of the Plan, provided that the Administrator may, in its sole discretion, refuse to accept any form of consideration at the time of any Option exercise. 

Exercise of an Option in any manner shall result in a decrease in the number of Shares that thereafter may be 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. 
 (v)
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. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is
issued, except as provided in Section 14 of the Plan. 
 (b) Termination of Employment or Consulting
Relationship. Except as otherwise set forth in this Section 9(b), the Administrator shall establish and set forth in the applicable Option Agreement the terms and conditions upon which an Option shall remain exercisable, if at all,
following termination of an Optionee’s Continuous Service Status, which provisions may be waived or modified by the Administrator at any time. Unless the Administrator otherwise provides in the Option Agreement, to the extent that the Optionee
is not vested in Optioned Stock at the date of termination of his or her Continuous Service Status, or if the Optionee (or other person entitled to exercise the Option) does not exercise the Option to the extent so entitled within the time specified
in the Option Agreement or below (as applicable), the Option shall terminate and the Optioned Stock underlying the unexercised portion of the Option 

  
 -9-









 
shall revert to the Plan. In no event may any Option be exercised after the expiration of the Option term as set forth in the Option Agreement (and subject to Section 7). 

The following provisions (1) shall apply to the extent an Option Agreement does not specify the terms and conditions upon which an
Option shall terminate upon termination of an Optionee’s Continuous Service Status, and (2) establish the minimum post-termination exercise periods that may be set forth in an Option Agreement: 

(i) Termination other than Upon Disability or Death or for Cause. In the event of termination of Optionee’s Continuous
Service Status other than under the circumstances set forth in subsections (ii) through (iv) below, such Optionee may exercise an Option for 90 days following such termination to the extent the Optionee was vested in the Optioned Stock as
of the date of such termination. No termination shall be deemed to occur and this Section 9(b)(i) shall not apply if (i) the Optionee is a Consultant who becomes an Employee, or (ii) the Optionee is an Employee who becomes a
Consultant. 
 (ii) Disability of Optionee. In the event of termination of an Optionee’s Continuous Service
Status as a result of his or her disability (including a disability within the meaning of Section 22(e)(3) of the Code), such Optionee may exercise an Option at any time within twelve months following such termination to the extent the Optionee
was vested in the Optioned Stock as of the date of such termination. 
 (iii) Death of Optionee. In the event of
the death of an Optionee during the period of Continuous Service Status since the date of grant of the Option, or within thirty days following termination of Optionee’s Continuous Service Status, the Option may be exercised by Optionee’s
estate or by a person who acquired the right to exercise the Option by bequest or inheritance at any time within twelve months following the date of death, but only to the extent the Optionee was vested in the Optioned Stock as of the date of death
or, if earlier, the date the Optionee’s Continuous Service Status terminated. 
 (iv) Termination for Cause.
In the event of termination of an Optionee’s Continuous Service Status for Cause, any Option (including any exercisable portion thereof) held by such Optionee shall immediately terminate in its entirety upon first notification to the Optionee
of termination of the Optionee’s Continuous Service Status. If an Optionee’s employment or consulting relationship with the Company is suspended pending an investigation of whether the Optionee shall be terminated for Cause, all the
Optionee’s rights under any Option likewise shall be suspended during the investigation period and the Optionee shall have no right to exercise any Option. 
 (c) Buyout Provisions. The Administrator may at any time offer to buy out for a payment in cash or Shares an Option previously granted under the Plan based on such terms and conditions as
the Administrator shall establish and communicate to the Optionee at the time that such offer is made. 
 10. Stock
Purchase Rights. 

  
 -10-









 (a) Rights to Purchase. When the Administrator determines that it will offer
Stock Purchase Rights under the Plan, it shall advise the offeree in writing 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. In the case of a Stock Purchase Right granted prior to the date, if any, on which the Common Stock becomes a Listed Security and if required by the Applicable Laws at that time, the purchase
price of Shares subject to such Stock Purchase Rights shall not be less than 85% of the Fair Market Value of the Shares as of the date of the offer, or, in the case of a Ten Percent Holder, the price shall not be less than 100% of the Fair Market
Value of the Shares as of the date of the offer. If the Applicable Laws do not impose the requirements set forth in the preceding sentence and with respect to any Stock Purchase Rights granted after the date, if any, on which the Common Stock
becomes a Listed Security, the purchase price of Shares subject to Stock Purchase Rights shall be as determined by the Administrator. The offer to purchase Shares subject to Stock Purchase Rights shall be accepted by execution of a Restricted Stock
Purchase Agreement in the form determined by the Administrator. 
 (b) Repurchase Option. 

(i) General. Unless the Administrator determines otherwise, the Restricted Stock Purchase Agreement shall grant the
Company a repurchase option exercisable upon the voluntary or involuntary termination of the purchaser’s employment with the Company for any reason (including death or disability). Subject to any requirements of the Applicable Laws (including
without limitation Section 260.140.42(h) of the Rules of the California Corporations Commissioner), the terms of the Company’s repurchase option (including without limitation the price at which, and the consideration for which, it may be
exercised, and the events upon which it shall lapse) shall be as determined by the Administrator in its sole discretion and reflected in the Restricted Stock Purchase Agreement. 

(ii) Leave of Absence. The Administrator shall have the discretion to determine whether and to what extent the lapsing of
Company repurchase rights shall be tolled during any unpaid leave of absence; provided, however, that in the absence of such determination, such lapsing shall be tolled during any such unpaid leave (unless otherwise required by the Applicable Laws).
In the event of military leave, the lapsing of Company repurchase rights shall toll during any unpaid portion of such leave, provided that, upon a Participant’s returning from military leave (under conditions that would entitle him or her to
protection upon such return under the Uniform Services Employment and Reemployment Rights Act), he or she shall be given “vesting” credit with respect to Shares purchased pursuant to the Restricted Stock Purchase Agreement to the same
extent as would have applied had the Participant continued to provide services to the Company throughout the leave on the same terms as he or she was providing services immediately prior to such leave. 

(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. In addition, the provisions of Restricted Stock Purchase Agreements need not be the same with respect to each purchaser. 

  
 -11-









 (d) Rights as a Stockholder. Once the Stock Purchase Right is exercised, the
purchaser shall have the 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 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 14 of the Plan. 
 11. Restricted Stock Unit Awards. 
 (a) Restricted Stock Unit
Award Agreement. Each grant of Restricted Stock Unit Awards under the Plan shall be evidenced by a Restricted Stock Unit Award Agreement between the Participant and the Company. Such award shall be subject to all applicable terms and
conditions of the Plan and may be subject to any other terms and conditions which are not inconsistent with the Plan and which the Administrator deems appropriate for inclusion in a Restricted Stock Unit Award Agreement. The provisions of the
various Restricted Stock Unit Award Agreements entered into under the Plan need not be identical. 
 (b) Number of
Shares. Each Restricted Stock Unit Award Agreement shall specify the number of Shares covered by the Restricted Stock Unit Award and shall provide for the adjustment of such number in accordance with Section 14. 

(c) Consideration. At the time of grant of a Restricted Stock Unit Award, the Administrator will determine the
consideration, if any, to be paid by the Participant upon delivery of each share of Common Stock subject to the Restricted Stock Unit Award. The consideration to be paid (if any) by the Participant for each Share of Common Stock subject to a
Restricted Stock Unit Award may be paid in any form of legal consideration that may be acceptable to the Administrator in its sole discretion and permissible under Applicable Laws. 

(d) Vesting. At the time of the grant of a Restricted Stock Unit Award, the Administrator may impose such restrictions or
conditions to the vesting of the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate. 
 (e)
Payment. A Restricted Stock Unit Award may be settled by the delivery of Shares of Common Stock, their cash equivalent, any combination thereof or in any other form of consideration, as determined by the Administrator and contained in
the Restricted Stock Unit Award Agreement. 
 (f) Basic Term. The Restricted Stock Unit Award Agreement shall
specify the term of the Restricted Stock Unit Award. The term shall not exceed ten (10) years from the Date of Grant. Subject to the preceding sentence, the Administrator at its sole discretion shall determine when a Restricted Stock Unit Award is
to expire. 
 (g) Additional Restrictions. At the time of the grant of a Restricted Stock Unit Award, the
Administrator, as it deems appropriate, may impose such restrictions or conditions that delay the delivery of the Shares of Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to a time after the vesting of such
Restricted Stock Unit Award. 
 (h) Dividend Equivalents. Dividend equivalents may be credited in respect of
shares of Common Stock covered by a Restricted Stock Unit Award, as determined by the Administrator and contained in the Restricted Stock Unit Award Agreement. At the sole discretion of the Administrator, such dividend equivalents may be converted
into additional Shares of Common Stock covered by the Restricted Stock Unit Award in such manner as determined by the Administrator. Any additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents
will be subject to all of the same terms and conditions of the underlying Restricted Stock Unit Award Agreement to which they relate. 
 (i) Termination of Service. Except as otherwise provided in the applicable Restricted Stock Unit Award Agreement, such portion of a Restricted Stock Unit Award that has not vested will be
forfeited upon the Participant’s termination of Continuous Service Status. 
 (j) Withholding Taxes. As a
condition to the award, vesting or delivery of Shares subject to the Restricted Stock Unit Award, the Participant shall make such arrangements as the Administrator may require for the satisfaction of any federal, state, local or foreign withholding
tax obligations that may arise in connection with such event. 
 (k) Compliance with Section 409A of the Code.
Notwithstanding anything to the contrary set forth herein, any Restricted Stock Unit Award granted under the Plan that is not exempt from the requirements of Section 409A of the Code shall contain such provisions so that such Restricted Stock Unit
Award will comply with the requirements of Section 409A of the Code. Such restrictions, if any, shall be determined by the Administrator and contained in the Restricted Stock Unit Award Agreement evidencing such Restricted Stock Unit Award. For
example, such restrictions may include, without limitation, a requirement that any Shares of Common Stock that are to be issued in a year following the year in which the Restricted Stock Unit Award vests must be issued in accordance with a fixed
pre-determined schedule. 
 12. Taxes. 
 (a) As a condition of the grant, vesting or exercise of an Option, Stock Purchase Right, or Restricted Stock Unit Award granted under the Plan, the Participant (or in the case of the Participant’s
death, the person exercising the Option or Stock Purchase Right or receiving shares pursuant to a Restricted Stock Unit Award) shall make such arrangements as the Administrator may require for the satisfaction of any applicable federal, state, local
or foreign withholding tax obligations that may arise in connection with such grant, vesting or exercise of the Option or Stock Purchase Right or the issuance of Shares. The Company shall not be required to issue any Shares under the Plan until such
obligations are satisfied. If the Administrator allows the withholding or surrender of Shares to satisfy a Participant’s tax withholding obligations under this Section 12 (whether pursuant to Section 12(c), (d) or (e), or
otherwise), the Administrator shall not allow Shares to be withheld in an amount that exceeds the minimum statutory withholding rates for federal and state tax purposes, including payroll taxes. 

(b) In the case of an Employee and in the absence of any other arrangement, the Employee shall be deemed to have directed the Company to
withhold or collect from his or her compensation an amount sufficient to satisfy such tax obligations from the next payroll payment otherwise payable after the date of an exercise of the Option or Stock Purchase Right or issuance of shares pursuant
to a Restricted Stock Unit Award. 
 (c) This Section 12(c) shall apply only after the date, if any, upon which the Common
Stock becomes a Listed Security. In the case of a Participant other than an Employee (or in the case of an Employee where the next payroll payment is not sufficient to satisfy such tax obligations, with respect to any remaining tax obligations), in
the absence of any other arrangement and to the extent permitted under the Applicable Laws, the Participant shall be deemed to have elected to have the Company withhold from the Shares to be issued upon exercise of the Option or Stock Purchase Right
or upon settlement of a Restricted Stock Unit Award that number of Shares having a Fair Market Value determined as of the applicable Tax Date (as defined below) equal to the amount required to be withheld. For purposes of this Section 12, 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 under the Applicable Laws (the “Tax Date”). 

(d) If permitted by the Administrator, in its discretion, a Participant may satisfy his or her tax withholding obligations upon exercise
of an Option or Stock Purchase Right or settlement of a Restricted Stock Unit Award by surrendering to the Company Shares that have a Fair Market Value determined as of the applicable Tax Date equal to the amount required to be withheld. In the case
of shares previously acquired from the Company that are surrendered under this Section 12(d), such Shares must have been owned by the Participant for such period of time as is required for the Company to avoid adverse accounting charges.


  
 -12-









 (e) Any election or deemed election by a Participant to have Shares withheld to satisfy tax
withholding obligations under Section 12(c) or (d) above shall be irrevocable as to the particular Shares as to which the election is made and shall be subject to the consent or disapproval of the Administrator. Any election by a
Participant under Section 12(d) above must be made on or prior to the applicable Tax Date. 
 (f) In the event an election
to have Shares withheld is made by a Participant and the Tax Date is deferred under Section 83 of the Code because no election is filed under Section 83(b) of the Code, the Participant shall receive the full number of Shares with respect
to which the Option or Stock Purchase Right is exercised but such Participant shall be unconditionally obligated to tender back to the Company the proper number of Shares on the Tax Date. 

13. Non-Transferability of Stock Awards. 
 (a) General. Except as set forth in this Section 13, Stock Awards may not be sold, pledged, assigned, hypothecated, transferred or disposed of in any manner other than by will or by the
laws of descent or distribution. The designation of a beneficiary by an Optionee will not constitute a transfer. An Option or Stock Purchase Right may be exercised, during the lifetime of the holder of an Option or Stock Purchase Right, only by such
holder or a transferee permitted by this Section 13. 
 (b) Limited Transferability Rights. Notwithstanding
anything else in this Section 13, the Administrator may in its discretion grant Nonstatutory Stock Options that may be transferred by instrument to an inter vivos or testamentary trust in which the Options are to be passed to beneficiaries upon
the death of the trustor (settlor) or by gift or pursuant to domestic relations orders to “Immediate Family Members” (as defined below) of the Optionee. “Immediate Family” means any child, stepchild, grandchild, parent,
stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law (including adoptive relationships), a trust in which these persons have more than
fifty percent of the beneficial interest, a foundation in which these persons (or the Optionee) control the management of assets, and any other entity in which these persons (or the Optionee) own more than fifty percent of the voting interests.

 14. Adjustments Upon Changes in Capitalization, Merger or Certain Other Transactions. 

(a) Changes in Capitalization. Subject to any action required under Applicable Laws by the stockholders of the Company, the
number of Shares of Common Stock covered by each outstanding award, and the number of Shares of Common Stock that have been authorized for issuance under the Plan but as to which no Stock Awards have yet been granted or that have been returned to
the Plan upon cancellation or expiration of a Stock Award, as well as the price per Share of Common Stock covered by each such outstanding Stock Award, shall be proportionately adjusted for any increase or decrease in the number of issued


  
 -13-









 
Shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination, recapitalization or reclassification of the Common Stock, or any other increase or decrease
in the number of issued Shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt
of consideration.” Such adjustment shall be made by the Administrator, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class,
or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares of Common Stock subject to a Stock Award. 

(b) Dissolution or Liquidation. In the event of the dissolution or liquidation of the Company, each Option and Stock
Purchase Right will terminate immediately prior to the consummation of such action, unless otherwise determined by the Administrator. 
 (c) Corporate Transaction. In the event of a Corporate Transaction (including without limitation a Change of Control), the Board or Committee may, in its discretion, (1) provide for the
assumption or substitution of, or adjustment to, each outstanding Stock Award by the successor corporation or a parent or subsidiary of the successor corporation (the “Successor Corporation”); (2) accelerate the vesting and
termination of outstanding Stock Awards, in whole or in part, so that Options, Stock Purchase Rights and Restricted Stock Unit Awards can be exercised before or otherwise in connection with the closing or completion of the transaction or event but
then terminate; and/or (3) provide for termination of Stock Awards as a result of the Corporate Transaction on such terms and conditions as it deems appropriate, including providing for the cancellation of Stock Awards for a cash payment to the
Participant. The Board or Committee need not provide for identical treatment of each outstanding award. 
 For purposes of this
Section 14(c), a Stock Award shall be considered assumed, without limitation, if, at the time of issuance of the stock or other consideration upon a Corporate Transaction or a Change of Control, as the case may be, each holder of a Stock Award
would be entitled to receive upon exercise of the award the same number and kind of shares of stock or the same amount of property, cash or securities as such holder would have been entitled to receive upon the occurrence of the transaction if the
holder had been, immediately prior to such transaction, the holder of the number of Shares of Common Stock covered by the award at such time (after giving effect to any adjustments in the number of Shares covered by the Stock Award as provided for
in this Section 14); provided that if such consideration received in the transaction is not solely common stock of the Successor Corporation, the Administrator may, with the consent of the Successor Corporation, provide for the consideration to
be received upon exercise of the award to be solely common stock of the Successor Corporation equal to the Fair Market Value of the per Share consideration received by holders of Common Stock in the transaction. 

(d) Certain Distributions. In the event of any distribution to the Company’s stockholders of securities of any other
entity or other assets (other than dividends payable in cash or stock of the Company) without receipt of consideration by the Company, the Administrator may, in its discretion, appropriately adjust the price per Share of Common Stock covered by each
outstanding Stock Award to reflect the effect of such distribution. 

  
 -14-









 15. Time of Granting Stock Awards. The date of grant of a Stock Award shall,
for all purposes, be the date on which the Administrator makes the determination granting such Stock Award, or such other date as is determined by the Administrator, provided that in the case of any Incentive Stock Option, the grant date shall be
the later of the date on which the Administrator makes the determination granting such Incentive Stock Option or the date of commencement of the Optionee’s employment relationship with the Company. Notice of the determination shall be given to
each Employee or Consultant to whom a Stock Award is so granted within a reasonable time after the date of such grant. 
 16.
Amendment and Termination of the Plan. 
 (a) Authority to Amend or Terminate. The Board may at any
time amend, alter, suspend or discontinue the Plan, but no amendment, alteration, suspension or discontinuation (other than an adjustment pursuant to Section 14 above) shall be made that would materially and adversely affect the rights of any
Optionee or holder of Stock Purchase Rights under any outstanding grant, without his or her consent. In addition, to the extent necessary and desirable to comply with the Applicable Laws, the Company shall obtain stockholder approval of any Plan
amendment in such a manner and to such a degree as required. 
 (b) Effect of Amendment or Termination. Except as
to amendments which the Administrator has the authority under the Plan to make unilaterally, no amendment or termination of the Plan shall materially and adversely affect Stock Awards already granted, unless mutually agreed otherwise between the
holder of the Stock Award and the Administrator, which agreement must be in writing and signed by the Stock Award holder and the Company. 
 17. Conditions Upon Issuance of Shares. Notwithstanding any other provision of the Plan or any agreement entered into by the Company pursuant to the Plan, the Company shall not be obligated,
and shall have no liability for failure, to issue or deliver any Shares under the Plan unless such issuance or delivery would comply with the Applicable Laws, with such compliance determined by the Company in consultation with its legal counsel. As
a condition to the exercise of an Option or Stock Purchase Right or the settlement of a Restricted Stock Unit Award, the Company may require the person exercising the 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 by law. Shares issued upon exercise of Stock Awards granted
prior to the date on which the Common Stock becomes a Listed Security shall be subject to a right of first refusal in favor of the Company pursuant to which the Participant will be required to offer Shares to the Company before selling or
transferring them to any third party on such terms and subject to such conditions as are reflected in the applicable Option Agreement, Restricted Stock Purchase Agreement or Restricted Stock Unit Agreement. In addition, awards issued prior to the
date on which the Common Stock becomes a Listed Security shall require the Participant to agree to a lock-up agreement in connection with public offerings of the Company’s stock that applies to all capital stock and rights to purchase capital
stock of the Company held by the Participant on such terms and subject to such conditions as are reflected in the applicable Option Agreement, Restricted Stock Purchase Agreement or Restricted Stock Unit Agreement.

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

19. Agreements. Options and Stock Purchase Rights shall be evidenced by Option Agreements, Restricted Stock Purchase
Agreements and Restricted Stock Unit Award Agreements, respectively, in such form(s) as the Administrator shall from time to time approve. 
 20. Stockholder Approval. If required by the Applicable Laws, continuance of the Plan shall be subject to approval by the stockholders of the Company within twelve (12) months before or
after the date the Plan is adopted. Such stockholder approval shall be obtained in the manner and to the degree required under the Applicable Laws.
