1. Purposes of the Plan. The purposes of this 2015 Stock Plan are to attract and retain the best available personnel for
positions of substantial responsibility, to provide additional incentive to Employees and Consultants, and to promote the success of the Company’s business. Options granted under the Plan may be Incentive Stock Options 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 granted under the Plan.

 2. Definitions. As used herein, the following definitions shall apply: 

(a) “Administrator” means the Board or a Committee. 

(b) “Affiliate” means (i) an entity other than a Subsidiary which, together with the Company, is
under common control of a third person or entity and (ii) an entity other than a Subsidiary in which the Company and /or one or more Subsidiaries own a controlling interest. 

(c) “Applicable Laws” means all applicable laws, rules, regulations and requirements, including, but not
limited to, all applicable U.S. federal or state laws, any Stock Exchange rules or regulations, and the applicable laws, rules or regulations of any other country or jurisdiction where Options or Restricted Stock are granted under the Plan or
Participants reside or provide services, as such laws, rules, and regulations shall be in effect from time to time.

to a securities broker (on a form prescribed by the Company) to sell Shares and to deliver all or part of the sale proceeds to the Company in payment of such amount. 

(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 any of the following
reasons: (i) any 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 duties and Participant’s

reputation; or (viii) Participant’s unauthorized use or disclosure of any proprietary information or trade secrets of the Company or any other party to whom the Participant owes an obligation of nondisclosure as a result of his or her

Continuous Service Status has been terminated for Cause shall be made in good faith by the Company and shall be final and binding on the Participant. The foregoing definition does not in any way limit the Company’s ability to terminate a

terminated on the 1st day following such 3-month period and the Incentive Stock Option shall thereafter automatically become a Nonstatutory Stock Option in accordance with Applicable Laws, unless reemployment
upon the expiration of such leave is guaranteed by contract or statute, or unless provided otherwise pursuant to a written Company policy. Also, Continuous Service Status as an Employee or 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 Employee to a Consultant or from a Consultant to an Employee.

the Treasury Regulations promulgated there under, any Shares that again become available for issuance pursuant to the remaining provisions of this Section 3. 

4. Administration of the Plan.  

(a) General. The Plan shall be administered by the Board, a Committee appointed by the Board, or 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. 

(b) Committee Composition. If a Committee has been appointed pursuant to this Section 4, such Committee shall
continue to serve in its designated capacity until otherwise directed by the Board. From time to time the Board may increase the size of any Committee and appoint additional members thereof, remove members (with or without cause) and 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.

(iv) to approve the form(s) of agreement(s) and other related documents used under the Plan; 

(v) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder, which terms and
conditions include but are not limited to the exercise or purchase price, the time or times when Awards may vest and/or be exercised (which may be based on performance criteria), the circumstances (if any) when vesting will be accelerated or
forfeiture restrictions will be waived, and any restriction or limitation regarding any Award, Optioned Stock, or Restricted Stock; 
 (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 

  
 -7- 













 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 good 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)

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 until June 26, 2025 unless sooner terminated under Section 14 below. 

7. Options.

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

 -8- 













 (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 
 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. 

  
 -9- 













 (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 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: 

  
 -10- 













 (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). 

(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. 

  
 -11- 













 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. 

(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. 

(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 

  
 -13- 













 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.

 (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 (or any rights of such Awards) may not be sold, pledged,
encumbered, assigned, hypothecated, or disposed of or otherwise transferred 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. 

  
 -14- 













 (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 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 sell, assign, pledge, encumber or otherwise transfer, whether by sale, gift or otherwise, any Shares (or any rights of such 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- 













 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 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 

2015 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.
