or Nonstatutory Stock Options, as determined by the Administrator at the time of grant of an Option and subject to the applicable provisions of Section 422 of the Code and the regulations promulgated thereunder. Restricted Stock may also be

(h)    “Cause” for termination of a Participant’s Continuous Service Status will
exist (unless another definition is provided in an applicable Option Agreement, Restricted Stock Purchase Agreement, employment agreement or other applicable written agreement) if the Participant’s Continuous Service Status is terminated for

material breach by Participant of any material written agreement between Participant and the Company and Participant’s failure to cure such breach within 30 days after receiving written
notice thereof; (ii) any failure by Participant to comply with the Company’s material written policies or rules as they may be in effect from time to time; (iii) neglect or persistent unsatisfactory performance of Participant’s

Consultant shall not be considered interrupted or terminated in the case of a transfer between locations of the Company or between the Company, its Parents, Subsidiaries or Affiliates, or their respective successors, or a change in status from an

4.    Administration of the Plan.

any 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 Applicable Laws, the Board may authorize one or more officers
of the Company to make Awards under the Plan to Employees and Consultants (who are not subject to Section 16 of the Exchange Act) within parameters specified by the Board.

appoint new members in substitution therefor, fill vacancies (however caused) and dissolve a Committee and thereafter directly administer the Plan, all to the extent permitted by Applicable Laws and, in the case of a Committee 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.

 -6- 













 (vi)    to amend any outstanding Award or agreement related to any
Optioned Stock or Restricted Stock, including any amendment adjusting vesting (e.g., in connection with a change in the terms or conditions under which such person is providing services to the Company), provided that no amendment shall be made that
would materially and adversely affect the rights of any Participant without his or her consent; 
 (vii)    to determine
whether and under what circumstances an Option may be settled in cash under Section 7(c)(iii) below instead of Common Stock; 

(viii)    subject to Applicable Laws, to implement an Option Exchange Program and establish the terms and conditions of
such Option Exchange Program without consent of the holders of capital stock of the Company, provided that no amendment or adjustment to an Option that would materially and adversely affect the rights of any Participant shall be made without his or
her consent; 
 (ix)    to approve addenda pursuant to Section 18 below or to grant Awards to, or to modify the
terms of, any outstanding Option Agreement or Restricted Stock Purchase Agreement or any agreement related to any Optioned Stock or Restricted Stock held by Participants who are foreign nationals or employed outside of the United States with such
terms and conditions as the Administrator deems necessary or appropriate to accommodate differences in local law, tax policy or custom which deviate from the terms and conditions set forth in this Plan to the extent necessary or appropriate to
accommodate such differences; and 
 (x)    to construe and interpret the terms of the Plan, any Option Agreement or
Restricted Stock Purchase Agreement, and any agreement related to any Optioned Stock or Restricted Stock, which constructions, interpretations and decisions shall be final and binding on all Participants. 

(d)    Indemnification. To the maximum extent permitted by Applicable Laws, each member of the
Committee (including officers of the Company, if applicable), or of the Board, as applicable, shall be indemnified and held harmless by the Company against and from (i) any loss, cost, liability, or expense that may be imposed upon or
reasonably incurred by him or her in connection with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan or
pursuant to the terms and conditions of any Award except for actions taken in bad faith or failures to act in bad faith, and (ii) any and all amounts paid by him or her in settlement thereof, with the Company’s approval, or paid by him or
her in satisfaction of any judgment in any such claim, action, suit, or proceeding against him or her, provided that such member shall give the Company an opportunity, at its own expense, to handle and defend any such claim, action, suit or
proceeding before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the
Company’s Certificate of Incorporation or Bylaws, by contract, as a matter of law, or otherwise, or under any other power that the Company may have to indemnify or hold harmless each such person.

 5.    Eligibility. 

(a)    Recipients of Grants. Nonstatutory Stock Options and Restricted Stock 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. Notwithstanding any
designation under Section 5(b) above, to the extent that the aggregate Fair Market Value of Shares with respect to which options designated as incentive stock options are exercisable for the first time by any Optionee during 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 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. Neither the Plan nor any Award shall confer upon any Employee or
Consultant any right with respect to continuation of an employment or consulting relationship with the Company (any Parent, Subsidiary or Affiliate), nor shall it interfere in any way with such Employee’s or Consultant’s right or the
Company’s (Parent’s, Subsidiary’s or Affiliate’s) right to terminate his or her employment or consulting relationship at any time, with or without cause. 

6.    Term of Plan. The Plan shall become effective upon its adoption by the Board and shall continue
in effect for a term of 10 years unless sooner terminated under Section 14 below. 
 7.    Options.

 (a)    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 10 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 5 years from the date of grant thereof or such shorter term as may be provided in the Option Agreement. 

(b)    Option Exercise Price and Consideration. 

(i)    Exercise Price. The per Share exercise price for the Shares to be issued pursuant to the
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: 

(1)    In the case of an Incentive Stock Option 

  
 -8- 













 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 on the date of grant; 

b.    granted to any other Employee, the per Share exercise price shall be no less than 100% of the Fair Market Value on
the date of grant; 
 (2)    Except as provided in subsection (3) below, in the case of a Nonstatutory Stock Option
the per Share exercise price shall be such price as is determined by the Administrator, provided that, if the per Share exercise price is less than 100% of the Fair Market Value on the date of grant, it shall otherwise comply with all Applicable
Laws, including Section 409A of the Code; and 
 (3)    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. 

(ii)    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 and to the extent required by Applicable Laws, shall be determined at the time of grant) and may consist
entirely of (1) cash; (2) check; (3) to the extent permitted under, and in accordance with, Applicable Laws, delivery of a promissory note with such recourse, interest, security and redemption provisions as the Administrator
determines to be appropriate (subject to the provisions of Section 152 of the Delaware General Corporation Law); (4) cancellation of indebtedness; (5) other previously owned 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; (6) a Cashless Exercise; (7) such other consideration and method of payment permitted under Applicable Laws; or (8) any combination of
the foregoing methods of payment. In making its determination as to the type of consideration to accept, the Administrator shall consider if acceptance of such consideration may be reasonably expected to benefit the Company and the Administrator
may, in its sole discretion, refuse to accept a particular form of consideration at the time of any Option exercise. 

(c)    Exercise of Option. 

(i)    General. 

(1)    Exercisability. Any Option granted hereunder shall be exercisable at such times and under
such conditions as determined by the Administrator, consistent with the terms of the Plan and reflected in the Option Agreement, including vesting requirements and/or performance criteria with respect to the Company, and Parent, Subsidiary or
Affiliate, and/or the Optionee. 
 (2)    Leave of Absence. The Administrator shall have the
discretion to determine at any time whether and to what extent the vesting of Options shall be tolled during any leave of absence; provided, however, that in the absence of such determination, vesting of Options shall continue during any paid leave
and shall be tolled during any unpaid 

  
 -9- 













 
leave (unless otherwise required by Applicable Laws). Notwithstanding the foregoing, in the event of military leave, vesting shall toll during any unpaid portion of such leave, provided that,
upon an Optionee’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 Optionee continued to provide services to the Company (or any Parent, Subsidiary or Affiliate, if applicable) throughout the leave on the same terms as he or she was providing
services immediately prior to such leave. 
 (3)    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. 
 (4)    Procedures for and Results of Exercise. An Option
shall be deemed exercised when written notice of such exercise has been received by the Company in accordance with the terms of the Option Agreement 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 and has paid, or made arrangements to satisfy, any applicable taxes, withholding, required deductions or other required payments in accordance with Section 9 below. The exercise of an Option
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. 

(5)    Rights as Holder of Capital Stock. 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 holder of capital stock 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 is issued, except as provided in Section 10 below. 

(ii)    Termination of Continuous Service Status. 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. To the extent that 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, the following provisions shall apply: 

(1)    General Provisions. 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 below, the Option shall terminate and the Optioned Stock underlying the unexercised portion of the Option 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 this Section 7). 

  
 -10- 













 (2)    Termination other than Upon Disability or Death or for
Cause. In the event of termination of an Optionee’s Continuous Service Status other than under the circumstances set forth in the subsections (3) through (5) below, such Optionee may exercise any outstanding Option at
any time within 3 months following such termination to the extent the Optionee is vested in the Optioned Stock. 

(3)    Disability of Optionee. In the event of termination of an Optionee’s Continuous Service
Status as a result of his or her Disability, such Optionee may exercise any outstanding Option at any time within 12 months following such termination to the extent the Optionee is vested in the Optioned Stock. 

(4)    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 any outstanding Option, or within 3 months following termination of the Optionee’s Continuous Service Status, the Option may be exercised by any beneficiaries designated in accordance with
Section 16 below, or if there are no such beneficiaries, by the Optionee’s estate, or by a person who acquired the right to exercise the Option by bequest or inheritance, at any time within 12 months following the date the Optionee’s
Continuous Service Status terminated, but only to the extent the Optionee is vested in the Optioned Stock. 

(5)    Termination for Cause. In the event of termination of an Optionee’s Continuous Service
Status for Cause, any outstanding Option (including any vested 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
for Cause. If an Optionee’s Continuous Service Status is suspended pending an investigation of whether the Optionee’s Continuous Service Status will be terminated for Cause, all the Optionee’s rights under any Option, including the
right to exercise the Option, shall be suspended during the investigation period. Nothing in this Section 7(c)(ii)(5) shall in any way limit the Company’s right to purchase unvested Shares issued upon exercise of an Option as set forth in
the applicable Option Agreement. 
 (iii)    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. 

8.    Restricted Stock. 

(a)    Rights to Purchase. When a right to purchase or receive Restricted Stock is granted under the
Plan, the Company shall advise the recipient 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, if any (which shall be as
determined by the Administrator, subject to Applicable Laws, including any applicable securities laws), and the time within which such person must accept such offer. The permissible consideration for Restricted Stock shall be determined by the
Administrator and shall be the same as is set forth in Section 7(b)(ii) above with respect to exercise of Options. The offer to purchase Shares shall be accepted by execution of a Restricted Stock Purchase Agreement in the form determined by
the Administrator. 

  
 -11- 













 (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 Participant’s Continuous Service Status for any reason (including death or Disability) at a purchase price for Shares equal
to the original purchase price paid by the purchaser to the Company for such Shares and may be paid by cancellation of any indebtedness of the purchaser to the Company. The repurchase option shall lapse at such rate as the Administrator may
determine. 
 (ii)    Leave of Absence. The Administrator shall have the discretion to determine
at any time whether and to what extent the lapsing of Company repurchase rights shall be tolled during any leave of absence; provided, however, that in the absence of such determination, such lapsing shall continue during any paid leave and shall be
tolled during any unpaid leave (unless otherwise required by Applicable Laws). Notwithstanding the foregoing, 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 (or any Parent, Subsidiary or Affiliate, if applicable)
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 Participant.

 (d)    Rights as a Holder of Capital Stock. Once the Restricted Stock is purchased, the
Participant shall have the rights equivalent to those of a holder of capital stock, and shall be a record holder when his or her purchase and the issuance of the Shares 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 Restricted Stock is purchased, except as provided in Section 10 below. 

9.    Taxes. 

(a)    As a condition of the grant, vesting and exercise of an Award, the Participant (or in the case of the
Participant’s death or a permitted transferee, the person holding or exercising the Award) shall make such arrangements as the Administrator may require for the satisfaction of any applicable U.S. federal, state, local or foreign tax,
withholding, and any other required deductions or payments that may arise in connection with such Award. The Company shall not be required to issue any Shares under the Plan until such obligations are satisfied. 

  
 -12- 













 (b)    The Administrator may, to the extent permitted under Applicable
Laws, permit a Participant (or in the case of the Participant’s death or a permitted transferee, the person holding or exercising the Award) to satisfy all or part of his or her tax, withholding, or any other required deductions or payments by
Cashless Exercise or by surrendering Shares (either directly or by stock attestation) that he or she previously acquired; provided that, unless specifically permitted by the Company, any such Cashless Exercise must be an approved broker-assisted
Cashless Exercise or the Shares withheld in the Cashless Exercise must be limited to avoid financial accounting charges under applicable accounting guidance and any such surrendered Shares must have been previously held for any minimum duration
required to avoid financial accounting charges under applicable accounting guidance. Any payment of taxes by surrendering Shares to the Company may be subject to restrictions, including, but not limited to, any restrictions required by rules of the
Securities and Exchange Commission. 
 10.    Adjustments Upon Changes in Capitalization, Merger or Certain Other
Transactions. 
 (a)    Changes in Capitalization. Subject to any action required
under Applicable Laws by the holders of capital stock of the Company, (i) the numbers and class of Shares or other stock or securities: (x) available for future Awards under Section 3 above and (y) covered by each outstanding
Award, (ii) the exercise price per Share of each such outstanding Option, and (iii) any repurchase price per Share applicable to Shares issued pursuant to any Award, shall be automatically proportionately adjusted in the event of a stock
split, reverse stock split, stock dividend, combination, consolidation, reclassification of the Shares or subdivision of the Shares. In the event of any increase or decrease in the number of issued Shares effected without receipt of consideration by
the Company, a declaration of an extraordinary dividend with respect to the Shares payable in a form other than Shares in an amount that has a material effect on the Fair Market Value, a recapitalization (including a recapitalization through a large
nonrecurring cash dividend), a rights offering, a reorganization, merger, a spin-off, split-up, change in corporate structure or a similar occurrence, the Administrator
shall make appropriate adjustments, in its discretion, in one or more of (i) the numbers and class of Shares or other stock or securities: (x) available for future Awards under Section 3 above and (y) covered by each outstanding
Award, (ii) the exercise price per Share of each outstanding Option and (iii) any repurchase price per Share applicable to Shares issued pursuant to any Award, and any such adjustment by the Administrator shall be made in the
Administrator’s sole and absolute discretion and 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 subject to an Award. If, by reason of a transaction described in this Section 10(a) or an adjustment pursuant to this
Section 10(a), a Participant’s Award agreement or agreement related to any Optioned Stock or Restricted Stock covers additional or different shares of stock or securities, then such additional or different shares, and the Award agreement
or agreement related to the Optioned Stock or Restricted Stock in respect thereof, shall be subject to all of the terms, conditions and restrictions which were applicable to the Award, Optioned Stock and Restricted Stock prior to such adjustment.


  
 -13- 













 (b)    Dissolution or Liquidation. In the event of
the dissolution or liquidation of the Company, each Award will terminate immediately prior to the consummation of such action, unless otherwise determined by the Administrator. 

(c)    Corporate Transactions. In the event of (i) a transfer of all or substantially all of the
Company’s assets, (ii) a merger, consolidation or other capital reorganization or business combination transaction of the Company with or into another corporation, entity or person, or (iii) the consummation of a transaction, or
series of related transactions, in which any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) becomes the “beneficial owner” (as defined in Rule 13d-3 of the
Exchange Act), directly or indirectly, of more than 50% of the Company’s then outstanding capital stock (a “Corporate Transaction”), each outstanding Award (vested or unvested) will be treated as the Administrator determines,
which determination may be made without the consent of any Participant and need not treat all outstanding Awards (or portion thereof) in an identical manner. Such determination, without the consent of any Participant, may provide (without
limitation) for one or more of the following in the event of a Corporate Transaction: (A) the continuation of such outstanding Awards by the Company (if the Company is the surviving corporation); (B) the assumption of such outstanding Awards by
the surviving corporation or its parent; (C) the substitution by the surviving corporation or its parent of new options or equity awards for such Awards; (D) the cancellation of such Awards in exchange for a payment to the Participants
equal to the excess of (1) the Fair Market Value of the Shares subject to such Awards as of the closing date of such Corporate Transaction over (2) the exercise price or purchase price paid or to be paid for the Shares subject to the
Awards; or (E) the cancellation of any outstanding Options or an outstanding right to purchase Restricted Stock, in either case, for no consideration. 

11.    Non-Transferability of Awards. 

(a)    General. Except as set forth in this Section 11, 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 a Participant will not constitute a transfer. An Option may be exercised, during the
lifetime of the holder of the Option, only by such holder or a transferee permitted by this Section 11. 

(b)    Limited Transferability Rights. Notwithstanding anything else in this Section 11, the
Administrator may in its sole discretion provide that any Nonstatutory Stock Options 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 to Family Members. Further, beginning with (i) the period when the Company begins to rely on the exemption described in Rule 12h-1(f)(1) promulgated under the Exchange Act, as
determined by the Board in its sole discretion, and (ii) ending on the earlier of (A) the date when the Company ceases to rely on such exemption, as determined by the Board in its sole discretion, or (B) the date when the Company
becomes subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, an Option, or prior to exercise, the Shares subject to the Option, may not be pledged, hypothecated or otherwise transferred or disposed of, in any
manner, including by entering into any short position, any “put equivalent position” or any “call equivalent position” (as defined in Rule 16a-1(h) and
Rule 16a-1(b) of the Exchange Act, respectively), other than to (i) persons who are Family Members through gifts or domestic relations orders, or (ii) to an


  
 -14- 













 
executor or guardian of the Participant upon the death or disability of the Participant. Notwithstanding the foregoing sentence, the Board, in its sole discretion, may permit transfers of
Nonstatutory Stock Options to the Company or in connection with a Change of Control or other acquisition transactions involving the Company to the extent permitted by Rule 12h-1(f). 

12.    Non-Transferability of Stock Underlying Awards. 

(a)    General. Notwithstanding anything to the contrary, no stockholder shall transfer, whether by
sale, gift or otherwise, any Shares acquired from any Award (including, without limitation, Shares acquired upon exercise of an Option) to any person or entity unless such transfer is approved by the Company prior to such transfer, which approval
may be granted or withheld in the Company’s sole and absolute discretion. Any purported transfer effected in violation of this Section 12 shall be null and void and shall have no force or effect and the Company shall not be required
(i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of the Plan or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any
purchaser or other transferee to whom such Shares shall have been so transferred. 
 (b)    Approval
Process. Any stockholder seeking the approval of the Board to transfer some or all of its Shares shall give written notice thereof to the Secretary of the Company and such request for transfer shall be subject to such right of first
refusal, transfer provisions and any other terms and conditions as may be set forth in the applicable Option Agreement, Restricted Stock Purchase Agreement or other applicable written agreement. 

13.    Time of Granting Awards. The date of grant of an Award shall, for all purposes, be the date on
which the Administrator makes the determination granting such Award, or such other date as is determined by the Administrator. 

14.    Amendment and Termination of the Plan. The Board may at any time amend or terminate the Plan,
but no amendment or termination shall be made that would materially and adversely affect the rights of any Participant under any outstanding Award, without his or her consent. In addition, to the extent necessary and desirable to comply with
Applicable Laws, the Company shall obtain the approval of holders of capital stock with respect to any Plan amendment in such a manner and to such a degree as required. 

15.    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 Applicable
Laws, with such compliance determined by the Company in consultation with its legal counsel. As a condition to the exercise of any Option or purchase of any Restricted Stock, the Company may require the person exercising the Option or purchasing the
Restricted Stock to represent and warrant at the time of any such exercise or purchase 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 advisable or required by Applicable Laws. Shares issued upon exercise of Options or purchase of Restricted Stock prior to the date, if ever, on which the Common Stock becomes a Listed Security shall be subject to a
right of first refusal in favor of 

  
 -15- 













 
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 is reflected in the applicable Option Agreement or Restricted Stock Purchase Agreement. 

16.    Beneficiaries. If permitted by the Company, a Participant may designate one or more
beneficiaries with respect to an Award by timely filing the prescribed form with the Company. A beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Participant’s death. Except as
otherwise provided in an Award Agreement, if no beneficiary was designated or if no designated beneficiary survives the Participant, then after a Participant’s death any vested Award(s) shall be transferred or distributed to the
Participant’s estate or to any person who has the right to acquire the Award by bequest or inheritance. 

17.    Approval of Holders of Capital Stock. If required by Applicable Laws, continuance of the Plan
shall be subject to approval by the holders of capital stock of the Company within 12 months before or after the date the Plan is adopted or, to the extent required by Applicable Laws, any date the Plan is amended. Such approval shall be obtained in
the manner and to the degree required under Applicable Laws. 
 18.    Addenda. The Administrator
may approve such addenda to the Plan as it may consider necessary or appropriate for the purpose of granting Awards to Employees or Consultants, which Awards may contain such terms and conditions as the Administrator deems necessary or appropriate
to accommodate differences in local law, tax policy or custom, which may deviate from the terms and conditions set forth in this Plan. The terms of any such addenda shall supersede the terms of the Plan to the extent necessary to accommodate such
differences but shall not otherwise affect the terms of the Plan as in effect for any other purpose. 

19.    Information to Holders of Options. In the event the Company is relying on the exemption
provided by Rule 12h-1(f) under the Exchange Act, the Company shall provide the information described in Rule 701(e)(3), (4) and (5) of the Securities Act of 1933, as amended, to all holders of Options in
accordance with the requirements thereunder until such time as the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act. The Company may request that holders of Options agree to keep the information
to be provided pursuant to this Section confidential. If the holder does not agree to keep the information to be provided pursuant to this Section confidential, then the Company will not be required to provide the information unless otherwise
required pursuant to Rule 12h-1(f)(1) of the Exchange Act.

 ADDENDUM A 

2014 Stock Plan 

(California Participants) 

Prior to the date, if ever, on which the Common Stock becomes a Listed Security and/or the Company is subject to the reporting requirements of
the Exchange Act, the terms set forth herein shall apply to Awards issued to California Participants. All capitalized terms used herein but not otherwise defined shall have the respective meanings set forth in the Plan. 

1.    The following rules shall apply to any Option in the event of termination of the Participant’s Continuous
Service Status: 
 (a)    If such termination was for reasons other than death, “Permanent Disability” (as
defined below), or Cause, the Participant shall have at least 30 days after the date of such termination to exercise his or her Option to the extent the Participant is entitled to exercise on his or her termination date, provided that in no event
shall the Option be exercisable after the expiration of the term as set forth in the Option Agreement. 
 (b)    If such
termination was due to death or Permanent Disability, the Participant shall have at least 6 months after the date of such termination to exercise his or her Option to the extent the Participant is entitled to exercise on his or her termination date,
provided that in no event shall the Option be exercisable after the expiration of the term as set forth in the Option Agreement. 
 “Permanent
Disability” for purposes of this Addendum shall mean the inability of the Participant, in the opinion of a qualified physician acceptable to the Company, to perform the major duties of the Participant’s position with the Company or any
Parent or Subsidiary because of the sickness or injury of the Participant. 
 2.    Notwithstanding anything to the
contrary in Section 10(a) of the Plan, the Administrator shall in any event make such adjustments as may be required by Section 25102(o) of the California Corporations Code. 

3.    Notwithstanding anything stated herein to the contrary, no Option shall be exercisable on or after the 10th
anniversary of the date of grant and any Award agreement shall terminate on or before the 10th anniversary of the date of grant. 

4.    The Company shall furnish summary financial information (audited or unaudited) of the Company’s financial
condition and results of operations, consistent with the requirements of Applicable Laws, at least annually to each California Participant during the period such Participant has one or more Awards outstanding, and in the case of an individual who
acquired Shares pursuant to the Plan, during the period such Participant owns such Shares; provided, however, the Company shall not be required to provide such information if (i) the issuance is limited to key persons whose duties in connection
with the Company assure their access to equivalent information or (ii) the Plan or any agreement complies with all conditions of Rule 701 of the Securities Act of 1933, as amended; provided that for purposes of determining such compliance, any
registered domestic partner shall be considered a “family member” as that term is defined in Rule 701.
