Option or Stock Purchase Right under the Plan, in payment of the exercise price thereof or tax withholding thereon, may again be optioned, granted or awarded hereunder, subject to the limitations of this Section 3. If Shares of Restricted Stock
are repurchased by the Company at their original purchase price, such Shares shall become available for future grant under the Plan (unless the Plan has terminated). Notwithstanding the provisions of this Section 3, no Shares may again be
optioned, granted or awarded if such action would cause an Incentive Stock Option to fail to qualify as an Incentive Stock Option under Code Section 422. 

4.    Administration of the Plan. 

(a)    Administrator. Unless and until the Board delegates administration to a Committee as set forth below, the
Plan shall be administered by the Board. The Board may delegate administration of the Plan to a Committee or Committees of one or more members of the Board, and the term “Committee” shall apply to any person or persons to whom such
authority has been delegated. If administration is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board, including the power to delegate to a
subcommittee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board shall thereafter be to the Committee or subcommittee), subject, however, to such resolutions, not inconsistent with the
provisions of the Plan, as may be adopted from time to time by the Board. Notwithstanding the foregoing, however, from and after the Public Trading Date, a Committee of the Board shall administer the Plan and the Committee shall consist solely of
two or more Independent Directors each of whom is an “outside director,” within the meaning of Section 162(m) of the Code, a “non-employee director,” within the meaning of Rule 16b-3, and qualifies as “independent” within the meaning of any applicable stock exchange listing requirements. Members of the Committee shall also satisfy any other legal requirements applicable to
membership on the 

  
 4 








 
Committee, including requirements under the Sarbanes-Oxley Act of 2002 and other Applicable Laws. Within the scope of such authority, the Board or the Committee may (i) delegate to a
committee of one or more members of the Board who are not Independent Directors the authority to grant awards under the Plan to eligible persons who are either (1) not then “covered employees,” within the meaning of Section 162(m) of
the Code and are not expected to be “covered employees” at the time of recognition of income resulting from such award or (2) not persons with respect to whom the Company wishes to comply with Section 162(m) of the Code and/or
(ii) delegate to a committee of one or more members of the Board who are not “non-employee directors,” within the meaning of Rule 16b-3, the authority to
grant awards under the Plan to eligible persons who are not then subject to Section 16 of the Exchange Act. The Board may abolish the Committee at any time and revest in the Board the administration of the Plan. Appointment of Committee members
shall be effective upon acceptance of appointment. Committee members may resign at any time by delivering written notice to the Board. Vacancies in the Committee may only be filled by the Board. 

(b)    Powers of the Administrator. Subject to the provisions of the Plan and 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 sole 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 such 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 vest or 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 Right or the Common Stock relating thereto, based in each case on such factors as the Administrator, in its sole discretion, shall determine); 

(vi)    to determine whether to offer to buyout a previously granted Option as provided in subsection 10(i) and to
determine the terms and conditions of such offer and buyout (including whether payment is to be made in cash or Shares); 

(vii)    to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations
relating to sub-plans established for the purpose of qualifying for preferred tax treatment under foreign tax laws; 

(viii)    to allow Holders to satisfy withholding tax 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 amount 

  
 5 








 
required to be withheld based on the statutory withholding rates for federal and state tax purposes that apply to supplemental taxable income. 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 Holders 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; 
 (ix)    to amend the Plan or any Option or Stock Purchase Right granted under the Plan as provided in
Section 15; and 
 (x)    to construe and interpret the terms of the Plan and awards granted pursuant to the Plan
and to exercise such powers and perform such acts as the Administrator deems necessary or desirable to promote the best interests of the Company which are not in conflict with the provisions of the Plan. 

(c)    Effect of Administrator’s Decision. All decisions, determinations and interpretations of the
Administrator shall be final and binding on all Holders. 
 5.    Eligibility.
Non-Qualified Stock Options and Stock Purchase Rights may be granted to Service Providers. Incentive Stock Options may be granted only to Employees. If otherwise eligible, a Service Provider who has been
granted an Option or Stock Purchase Right may be granted additional Options or Stock Purchase Rights. 

6.    Limitations. 

(a)    Each Option shall be designated by the Administrator in the Option Agreement as either an Incentive Stock Option or
a Non-Qualified Stock Option. However, notwithstanding such designations, to the extent that the aggregate Fair Market Value of Shares subject to a Holder’s Incentive Stock Options and other incentive
stock options granted by the Company, any Parent or Subsidiary, which become exercisable for the first time during any calendar year (under all plans of the Company or any Parent or Subsidiary) exceeds $100,000, such excess Options or other options
shall be treated as Non-Qualified 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, and the Fair Market Value of the Shares shall be determined as of the time of grant. 

(b)    Neither the Plan, any Option nor any Stock Purchase Right shall confer upon a Holder any right with respect to
continuing the Holder’s employment or consulting relationship with the Company, nor shall they interfere in any way with the Holder’s right or the Company’s right to terminate such employment or consulting relationship at any time,
with or without cause. 
 (c)    No Service Provider shall be granted, in any calendar year, Options or Stock Purchase
Rights to purchase more than 1,278,667 Shares; provided, however, that the foregoing limitation shall not apply prior to the Public Trading Date and, following the Public Trading Date, the foregoing limitation shall not apply until the
earliest of: (i) the first material modification of the Plan (including any increase in the number of shares reserved for issuance under the Plan in accordance with Section 3); (ii) the issuance of all of the shares of Common


  
 6 








 
Stock reserved for issuance under the Plan; (iii) the expiration of the Plan; (iv) the first meeting of stockholders at which Directors of the Company are to be elected that occurs
after the close of the third (3rd) calendar year following the calendar year in which occurred the first registration of an equity security of the Company under Section 12 of the Exchange Act
or (v) such other date required by Section 162(m) of the Code and the rules and regulations promulgated thereunder. The foregoing limitation shall be adjusted proportionately in connection with any change in the Company’s capitalization as
described in Section 13. For purposes of this Section 6(c), if an Option is canceled in the same calendar year it was granted (other than in connection with a transaction described in Section 13), the canceled Option will be counted
against the limit set forth in this Section 6(c). For this purpose, if the exercise price of an Option is reduced, the transaction shall be treated as a cancellation of the Option and the grant of a new Option. 

7.    Term of Plan. The Plan shall become effective upon its initial adoption by the Board and shall continue in
effect until it is terminated under Section 15 of the Plan. No Options or Stock Purchase Rights may be issued under the Plan after the tenth (10th) anniversary of the earlier of (i) the date upon which the Plan is adopted by the Board or
(ii) the date the Plan is approved by the stockholders. 
 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 a Holder who, at the time the Option is
granted, owns (or is treated as owning under Code Section 424) 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)    Except as provided in Section 13, 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
(or is treated as owning under Code Section 424) 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 per Share exercise price shall be no less than one
hundred ten percent (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 one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

(ii)    In the case of a Non-Qualified Stock Option 

(A)    granted to a Service Provider who, at the time of grant of such Option, owns (or is treated as owning under Code
Section 424) stock representing more 

  
 7 








 
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 one hundred ten percent (110%) of the Fair
Market Value per Share on the date of the grant. 
 (B)    granted to any other Service Provider, the per Share
exercise price shall be no less than one-hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

(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)    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 (1) cash,
(2) check, (3) with the consent of the Administrator, a full recourse promissory note bearing interest (at no less than such rate as is a market rate of interest and which then precludes the imputation of interest under the Code), payable
upon such terms as may be prescribed by the Administrator, and structured to comply with Applicable Laws, (4) with the consent of the Administrator, other Shares which (x) in the case of Shares acquired from the Company, have been owned by
the Holder 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) with the
consent of the Administrator, surrendered Shares then issuable upon exercise of the Option having a Fair Market Value on the date of exercise equal to the aggregate exercise price of the Option or exercised portion thereof, (6) with the consent
of the Administrator, property of any kind which constitutes good and valuable consideration, (7) with the consent of the Administrator, delivery of a notice that the Holder has placed a market sell order with a broker with respect to Shares
then issuable upon exercise of the Options and that the broker has been directed to pay a sufficient portion of the net proceeds of the sale to the Company in satisfaction of the Option exercise price, provided, that payment of such proceeds
is then made to the Company upon settlement of such sale, or (8) with the consent of the Administrator, any combination of the foregoing methods of payment. 

10.    Exercise of Option. 

(a)    Vesting; Fractional Exercises. Except as provided in Section 13, Options granted hereunder shall be
vested and 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; provided, however, that, except with regard to Options granted to Officers,
Directors or Consultants, in no event shall an Option granted hereunder become vested and exercisable at a rate of less than twenty percent (20%) per year over five (5) years from the date the Option is granted, subject to reasonable
conditions, such as continuing to be a Service Provider. An Option may not be exercised for a fraction of a Share. 

  
 8 








 (b)    Deliveries upon Exercise. All or a portion of an exercisable
Option shall be deemed exercised upon delivery of all of the following to the Secretary of the Company or his or her office: 

(i)    A written or electronic notice complying with the applicable rules established by the Administrator stating that
the Option, or a portion thereof, is exercised. The notice shall be signed by the Holder or other person then entitled to exercise the Option or such portion of the Option; 

(ii)    Such representations and documents as the Administrator, in its sole discretion, deems necessary or advisable to
effect compliance with Applicable Laws. The Administrator may, in its sole discretion, also take whatever additional actions it deems appropriate to effect such compliance, including, without limitation, placing legends on share certificates and
issuing stop transfer notices to agents and registrars; 
 (iii)    Upon the exercise of all or a portion of an
unvested Option pursuant to Section 10(h), a Restricted Stock purchase agreement in a form determined by the Administrator and signed by the Holder or other person then entitled to exercise the Option or such portion of the Option; and 

(iv)    In the event that the Option shall be exercised pursuant to Section 10(f) by any person or persons other than the
Holder, appropriate proof of the right of such person or persons to exercise the Option. 
 (c)    Conditions to
Delivery of Share Certificates. The Company shall not be required to issue or deliver any certificate or certificates for Shares purchased upon the exercise of any Option or portion thereof prior to fulfillment of all of the following
conditions: 
 (i)    The admission of such Shares to listing on all stock exchanges on which such class of stock is
then listed; 
 (ii)    The completion of any registration or other qualification of such Shares under any state or
federal law, or under the rulings or regulations of the Securities and Exchange Commission or any other governmental regulatory body which the Administrator shall, in its sole discretion, deem necessary or advisable; 

(iii)    The obtaining of any approval or other clearance from any state or federal governmental agency which the
Administrator shall, in its sole discretion, determine to be necessary or advisable; 
 (iv)    The lapse of such
reasonable period of time following the exercise of the Option as the Administrator may establish from time to time for reasons of administrative convenience; and 

(v)    The receipt by the Company of full payment for such Shares, including payment of any applicable withholding tax,
which in the sole discretion of the Administrator may be in the form of consideration used by the Holder to pay for such Shares under Section 9(b). 

  
 9 








 (d)    Termination of Relationship as a Service Provider. If a Holder
ceases to be a Service Provider other than by reason of the Holder’s disability or death, such Holder may exercise his or her 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; provided, however, that prior to the Public Trading Date, such period of time shall not be less than thirty (30) days (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 Holder’s termination. If, on the date of termination, the Holder is not vested as to
his or her entire Option, the Shares covered by the unvested portion of the Option immediately cease to be issuable under the Option and shall again become available for issuance under the Plan. If, after termination, the Holder does not exercise
his or her Option within the time period specified herein, the Option shall terminate, and the Shares covered by such Option shall again become available for issuance under the Plan. 

(e)    Disability of Holder. If a Holder ceases to be a Service Provider as a result of the Holder’s
disability, the Holder may exercise his or her 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; provided, however, that prior to the Public Trading
Date, such period of time shall not be less than six (6) months (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 Holder’s termination. If such disability is not a “disability” as such term is defined in Section 22(e)(3) of the Code, in the case of an Incentive Stock Option
such Incentive Stock Option shall automatically cease to be treated as an Incentive Stock Option and shall be treated for tax purposes as a Non-Qualified Stock Option from and after the day which is three
(3) months and one (1) day following such termination. If, on the date of termination, the Holder is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall immediately cease to be issuable
under the Option and shall again become available for issuance under the Plan. If, after termination, the Holder does not exercise his or her Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option
shall again become available for issuance under the Plan. 
 (f)    Death of Holder. If a Holder dies while a
Service Provider, the Option may be exercised within such period of time as is specified in the Option Agreement provided, however, that prior to the Public Trading Date, such period of time shall not be less than six (6) months
(but in no event later than the expiration of the term of such Option as set forth in the Notice of Grant), by the Holder’s estate or by a person who acquires the right to exercise the Option by bequest or inheritance, but only to the extent
that the Option is vested on the date of death. In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for twelve (12) months following the Holder’s termination. If, at the time of death, the Holder
is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall immediately cease to be issuable under the Option and shall again become available for issuance under the Plan. The Option may be exercised
by the executor or administrator of the Holder’s estate or, if none, by the person(s) entitled to exercise the Option under the Holder’s will or the laws of descent or distribution. If the Option is not so exercised within the time
specified herein, the Option shall terminate, and the Shares covered by such Option shall again become available for issuance under the Plan. 

  
 10 








 (g)    Regulatory Extension. A Holder’s Option Agreement may
provide that if the exercise of the Option following the termination of the Holder’s status as a Service Provider (other than upon the Holder’s death or Disability) would be prohibited at any time solely because the issuance of shares
would violate the registration requirements under the Securities Act, then the Option shall terminate on the earlier of (i) the expiration of the term of the Option set forth in Section 8 or (ii) the expiration of a period of three
(3) months after the termination of the Holder’s status as a Service Provider during which the exercise of the Option would not be in violation of such registration requirements. 

(h)    Early Exercisability. The Administrator may provide in the terms of a Holder’s Option Agreement that
the Holder may, at any time before the Holder’s status as a Service Provider terminates, exercise the Option in whole or in part prior to the full vesting of the Option; provided, however, that subject to Section 20, Shares acquired
upon exercise of an Option which has not fully vested may be subject to any forfeiture, transfer or other restrictions as the Administrator may determine in its sole discretion. 

(i)    Buyout Provisions. The Administrator may at any time offer to buyout for a payment in cash or Shares, an
Option previously granted, based on such terms and conditions as the Administrator shall establish and communicate to the Holder at the time that such offer is made. 

11.    Non-Transferability of Options and Stock Purchase Rights.
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 or distribution and may be exercised, during the lifetime of the Holder, only
by the Holder. 
 12.    Stock Purchase Rights. 

(a)    Rights to Purchase. Stock Purchase Rights may be issued either alone, in addition to, or in tandem with
Options 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 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; provided, however, that to the extent required to comply
with applicable securities laws, the purchase price of such Shares shall not be less than the purchase price requirements set forth in Section 260.140.42 of Title 10 of the California Code of Regulations. The offer shall be accepted by
execution of a Restricted Stock purchase agreement in the form determined by the Administrator. 
 (b)    Repurchase
Right. Unless the Administrator determines otherwise, the Restricted Stock purchase agreement shall grant the Company the right to repurchase Shares acquired upon exercise of a Stock Purchase Right upon the termination of the purchaser’s
status as a Service Provider for any reason. Subject to Section 20, the purchase price for Shares repurchased by the Company pursuant to such repurchase right and the rate at which such repurchase right shall lapse shall be determined by the
Administrator in its sole discretion, and shall be set forth in the Restricted Stock purchase agreement. 

  
 11 








 (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 Shareholder. Once the Stock Purchase Right is exercised, the purchaser shall have rights
equivalent to those of a shareholder and shall be a shareholder 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. 

13.    Adjustments upon Changes in Capitalization, Merger or Asset Sale. 

(a)    In the event that the Administrator determines that any dividend or other distribution (whether in the form of cash,
Common Stock, other securities, or other property), recapitalization, reclassification, stock split, reverse stock split, reorganization, merger, consolidation, split-up,
spin-off, combination, repurchase, liquidation, dissolution, or sale, transfer, exchange or other disposition of all or substantially all of the assets of the Company, or exchange of Common Stock or other
securities of the Company, issuance of warrants or other rights to purchase Common Stock or other securities of the Company, or other similar corporate transaction or event, in the Administrator’s sole discretion, affects the Common Stock such
that an adjustment is determined by the Administrator to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended by the Company to be made available under the Plan or with respect to any Option,
Stock Purchase Right or Restricted Stock, then the Administrator shall, in such manner as it may deem equitable, adjust any or all of: 

(i)    the number and kind of shares of Common Stock (or other securities or property) with respect to which Options or
Stock Purchase Rights may be granted or awarded (including, but not limited to, adjustments of the limitations in Section 3 on the maximum number and kind of shares which may be issued and adjustments of the maximum number of Shares that may be
purchased by any Holder in any calendar year pursuant to Section 6(c)); 
 (ii)    the number and kind of shares of
Common Stock (or other securities or property) subject to outstanding Options, Stock Purchase Rights or Restricted Stock; and 

(iii)    the grant or exercise price with respect to any Option or Stock Purchase Right. 

(b)    In the event of any transaction or event described in Section 13(a), the Administrator, in its sole discretion, and
on such terms and conditions as it deems appropriate, either by the terms of the Option, Stock Purchase Right or Restricted Stock or by action taken prior to the occurrence of such transaction or event and either automatically or upon the
Holder’s request, is hereby authorized to take any one or more of the following actions whenever the Administrator determines that such action is appropriate in order to prevent dilution or enlargement of the benefits or potential benefits
intended by the Company to be made available 

  
 12 








 
under the Plan or with respect to any Option, Stock Purchase Right or Restricted Stock granted or issued under the Plan or to facilitate such transaction or event: 

(i)    To provide for either the purchase of any such Option, Stock Purchase Right or Restricted Stock for an amount of
cash equal to the amount that could have been obtained upon the exercise of such Option or Stock Purchase Right or realization of the Holder’s rights had such Option, Stock Purchase Right or Restricted Stock been currently exercisable or
payable or fully vested or the replacement of such Option, Stock Purchase Right or Restricted Stock with other rights or property selected by the Administrator in its sole discretion; 

(ii)    To provide that such Option or Stock Purchase Right shall be exercisable as to all shares covered thereby,
notwithstanding anything to the contrary in the Plan or the provisions of such Option or Stock Purchase Right; 

(iii)    To provide that such Option, Stock Purchase Right or Restricted Stock be assumed by the successor or survivor
corporation, or a parent or subsidiary thereof, or shall be substituted for by similar options, rights or awards covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the
number and kind of shares and prices; 
 (iv)    To make adjustments in the number and type of shares of Common Stock
(or other securities or property) subject to outstanding Options and Stock Purchase Rights, and/or in the terms and conditions of (including the grant or exercise price), and the criteria included in, outstanding Options, Stock Purchase Rights or
Restricted Stock or Options, Stock Purchase Rights or Restricted Stock which may be granted in the future; and/or 

(v)    To provide that immediately upon the consummation of such event, such Option or Stock Purchase Right shall not be
exercisable and shall terminate; provided, that for a specified period of time prior to such event, such Option or Stock Purchase Right shall be exercisable as to all Shares covered thereby, and the restrictions imposed under an Option
Agreement or Restricted Stock purchase agreement upon some or all Shares may be terminated and, in the case of Restricted Stock, some or all shares of such Restricted Stock may cease to be subject to repurchase, notwithstanding anything to the
contrary in the Plan or the provisions of such Option, Stock Purchase Right or Restricted Stock purchase agreement. 

(c)    If the Company undergoes an Acquisition, then any surviving corporation or entity or acquiring corporation or
entity, or affiliate of such corporation or entity, may assume any Options, Stock Purchase Rights or Restricted Stock outstanding under the Plan or may substitute similar stock awards (including an award to acquire the same consideration paid to the
stockholders in the transaction described in this subsection 13(c)) for those outstanding under the Plan. In the event any surviving corporation or entity or acquiring corporation or entity in an Acquisition, or affiliate of such corporation or
entity, does not assume such Options, Stock Purchase Rights or Restricted Stock or does not substitute similar stock awards for those outstanding under the Plan, then with respect to (i) Options, Stock Purchase Rights or Restricted Stock held
by participants in the Plan whose status as a Service Provider has not terminated prior to such event, the vesting of such Options, Stock Purchase Rights or Restricted Stock (and, if 

  
 13 








 
applicable, the time during which such awards may be exercised) shall be accelerated and made fully exercisable and all restrictions thereon shall lapse at least ten (10) days prior to the
closing of the Acquisition (and the Options or Stock Purchase Rights terminated if not exercised prior to the closing of such Acquisition) and (ii) any other Options or Stock Purchase Rights outstanding under the Plan, such Options or Stock
Purchase rights shall be terminated if not exercised prior to the closing of the Acquisition. 
 (d)    Subject to
Section 3, the Administrator may, in its sole discretion, include such further provisions and limitations in any Option, Stock Purchase Right, Restricted Stock agreement or certificate, as it may deem equitable and in the best interests of the
Company. 
 (e)    The existence of the Plan, any Option Agreement or Restricted Stock purchase agreement and the
Options or Stock Purchase Rights granted hereunder shall not affect or restrict in any way the right or power of the Company or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in
the Company’s capital structure or its business, any merger or consolidation of the Company, any issue of stock or of options, warrants or rights to purchase stock or of bonds, debentures, preferred or prior preference stocks whose rights are
superior to or affect the Common Stock or the rights thereof or which are convertible into or exchangeable for Common Stock, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its assets or business, or
any other corporate act or proceeding, whether of a similar character or otherwise. 
 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 other date as
is determined by the Administrator. Notice of the determination shall be given to each Employee or Consultant 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 wholly or partially amend, alter, suspend or terminate
the Plan. However, without approval of the Company’s stockholders given within twelve (12) months before or after the action by the Board, no action of the Board may, except as provided in Section 13, increase the limits imposed in
Section 3 on the maximum number of Shares which may be issued under the Plan or extend the term of the Plan under Section 7. 

(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 Holder, unless mutually agreed otherwise between the Holder and the Administrator, which agreement must be in writing and signed by the Holder 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, Stock Purchase Rights or Restricted Stock granted or awarded under the Plan prior to the date
of such termination. 

  
 14 








 16.    Stockholder Approval. The Plan will be submitted for the
approval of the Company’s stockholders within twelve (12) months after the date of the Board’s initial adoption of the Plan. Options, Stock Purchase Rights or Restricted Stock may be granted or awarded prior to such stockholder
approval, provided that such Options, Stock Purchase Rights and Restricted Stock shall not be exercisable, shall not vest and the restrictions thereon shall not lapse prior to the time when the Plan is approved by the stockholders, and provided
further that if such approval has not been obtained at the end of said twelve-month period, all Options, Stock Purchase Rights and Restricted Stock previously granted or awarded under the Plan shall thereupon
be canceled and become null and void. 
 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.    Information
to Holders and Purchasers. Prior to the Public Trading Date and to the extent required by Section 260.140.46 of Title 10 of the California Code of Regulations, the Company shall provide to each Holder and to each individual who acquires
Shares pursuant to the Plan, not less frequently than annually during the period such Holder or purchaser has one or more Options or Stock Purchase Rights outstanding, and, in the case of an individual who acquires Shares pursuant to the Plan,
during the period such individual owns such Shares, copies of annual financial statements. Notwithstanding the preceding sentence, the Company shall not be required to provide such statements to key employees whose duties in connection with the
Company assure their access to equivalent information. 
 20.    Repurchase Provisions. The Administrator in its
sole discretion may provide that the Company may repurchase Shares acquired upon exercise of an Option or Stock Purchase Right upon the occurrence of certain specified events, including, without limitation, a Holder’s termination as a Service
Provider, divorce, bankruptcy or insolvency; provided, however, that any such repurchase right shall be set forth in the applicable Option Agreement or Restricted Stock purchase agreement or in another agreement referred to in such agreement;
and provided further, that to the extent required by Section 260.140.41 and Section 260.140.42 of Title 10 of the California Code of Regulations, any such repurchase right set forth in an Option or Stock Purchase Right granted prior
to the Public Trading Date to a person who is not an Officer, Director or Consultant shall be upon the following terms: (i) if the repurchase option gives the Company the right to repurchase the shares upon termination as a Service Provider at
not less than the Fair Market Value of the shares to be purchased on the date of termination of status as a Service Provider, then (A) the right to repurchase shall be exercised for cash or cancellation of purchase money indebtedness for the
shares within ninety (90) days of termination of status as a 

  
 15 








 
Service Provider (or in the case of shares issued upon exercise of Options or Stock Purchase Rights after such date of termination, within ninety (90) days after the date of the exercise) or
such longer period as may be agreed to by the Administrator and the Plan participant and (B) the right terminates when the shares become publicly traded and (ii) if the repurchase option gives the Company the right to repurchase the Shares
upon termination as a Service Provider at the original purchase price for such Shares, then (A) the right to repurchase at the original purchase price shall lapse at the rate of at least twenty percent (20%) of the shares per year over five
(5) years from the date the Option or Stock Purchase Right is granted (without respect to the date the Option or Stock Purchase Right was exercised or became exercisable) and (B) the right to repurchase shall be exercised for cash or
cancellation of purchase money indebtedness for the shares within ninety (90) days of termination of status as a Service Provider (or, in the case of shares issued upon exercise of Options or Stock Purchase Rights, after such date of
termination, within ninety (90) days after the date of the exercise) or such longer period as may be agreed to by the Company and the Plan participant. 

21.    Investment Intent. The Company may require a Plan participant, as a condition of exercising or acquiring
stock under any Option or Stock Purchase Right, (i) to give written assurances satisfactory to the Company as to the participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative
reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the
Option or Stock Purchase Right and (ii) to give written assurances satisfactory to the Company stating that the participant is acquiring the stock subject to the Option or Stock Purchase Right for the participant’s own account and not with
any present intention of selling or otherwise distributing the stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (A) the issuance of the shares upon the exercise or acquisition of
stock under the applicable Option or Stock Purchase Right has been registered under a then currently effective registration statement under the Securities Act or (B) as to any particular requirement, a determination is made by counsel for the
Company that such requirement need not be met in the circumstances under then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems
necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the stock. 

22.    Governing Law. The validity and enforceability of this Plan shall be governed by and construed in accordance
with the laws of the State of California without regard to otherwise governing principles of conflicts of law.
