 1. GENERAL. 

(a) Eligible Stock Award Recipients. The persons eligible to receive Stock Awards are Employees, Directors and Consultants. 

(b) Available Stock Awards. The Plan provides for the grant of the following Stock Awards: (i) Incentive Stock Options,
(ii) Nonstatutory Stock Options, (iii) Stock Appreciation Rights, (iv) Restricted Stock Awards, and (v) Restricted Stock Unit Awards. 

(c) Purpose. The Company, by means of the Plan, seeks to secure and retain the services of the group of persons eligible to receive
Stock Awards as set forth in Section 1(a), to provide incentives for such persons to exert maximum efforts for the success of the Company and any Affiliate, and to provide a means by which such eligible recipients may be given an opportunity to
benefit from increases in value of the Common Stock through the granting of Stock Awards. 
 2. ADMINISTRATION. 

(a) Administration by Board. The Board shall administer the Plan unless and until the Board delegates administration of the Plan to a
Committee or Committees, as provided in Section 2(c). 
 (b) Powers of Board. The Board shall have the power, subject to, and
within the limitations of, the express provisions of the Plan: 
 (i) To determine from time to time (A) which of the persons
eligible under the Plan shall be granted Stock Awards; (B) when and how each Stock Award shall be granted; (C) what type or combination of types of Stock Award shall be granted; (D) the provisions of each Stock Award granted (which
need not be identical), including the time or times when a person shall be permitted to receive cash or Common Stock pursuant to a Stock Award; (E) the number of shares of Common Stock with respect to which a Stock Award shall be granted to
each such person; and (F) the Fair Market Value applicable to a Stock Award. 
 (ii) To construe and interpret the Plan and Stock
Awards granted under it, and to establish, amend and revoke rules and regulations for administration of the Plan. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan or in any Stock Award
Agreement, in a manner and to the extent it shall deem necessary or expedient to make the Plan or Stock Award fully effective. 
 (iii)
To settle all controversies regarding the Plan and Stock Awards granted under it. 

  
 1. 








 (iv) To accelerate the time at which a Stock Award may first be exercised or the time
during which a Stock Award or any part thereof will vest in accordance with the Plan, notwithstanding the provisions in the Stock Award stating the time at which it may first be exercised or the time during which it will vest. 

(v) To suspend or terminate the Plan at any time. Suspension or termination of the Plan shall not impair rights and obligations under
any Stock Award granted while the Plan is in effect except with the written consent of the affected Participant. 
 (vi) To amend the
Plan in any respect the Board deems necessary or advisable, including, without limitation, amendments relating to Incentive Stock Options and certain nonqualified deferred compensation under Section 409A of the Code and/or to bring the Plan or
Stock Awards granted under the Plan into compliance therewith, subject to the limitations, if any, of applicable law. However, except as provided in Section 9(a) relating to Capitalization Adjustments, to the extent required by applicable law,
shareholder approval shall be required for any amendment of the Plan that either (A) materially increases the number of shares of Common Stock available for issuance under the Plan, (B) materially expands the class of individuals eligible
to receive Stock Awards under the Plan, (C) materially increases the benefits accruing to Participants under the Plan or materially reduces the price at which shares of Common Stock may be issued or purchased under the Plan, (D) materially
extends the term of the Plan, or (E) expands the types of Stock Awards available for issuance under the Plan. Except as provided above, rights under any Stock Award granted before amendment of the Plan shall not be impaired by any amendment of
the Plan unless (1) the Company requests the consent of the affected Participant, and (2) such Participant consents in writing.  

(vii) To submit any amendment to the Plan for shareholder approval, including, but not limited to, amendments to the Plan intended to
satisfy the requirements of Section 422 of the Code regarding Incentive Stock Options. 
 (viii) To approve forms of Stock Award
Agreements for use under the Plan and to amend the terms of any one or more Stock Awards, including, but not limited to, amendments to provide terms more favorable to the Participant than previously provided in the Stock Award Agreement, subject to
any specified limits in the Plan that are not subject to Board discretion; provided however, that, the rights under any Stock Award shall not be impaired by any such amendment unless (i) the Company requests the consent of the affected
Participant, and (ii) such Participant consents in writing. Notwithstanding the foregoing, subject to the limitations of applicable law, if any, and without the affected Participant’s consent, the Board may amend the terms of any one or
more Stock Awards if necessary to maintain the qualified status of the Stock Award as an Incentive Stock Option or to bring the Stock Award into compliance with Section 409A of the Code. 

(ix) Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best
interests of the Company and that are not in conflict with the provisions of the Plan or Stock Awards. 
 (x) To adopt such
procedures and sub-plans as are necessary or appropriate to permit participation in the Plan by Employees, Directors or Consultants who are foreign nationals or employed outside the United States. 

(xi) To effect, at any time and from time to time, with the consent of any adversely affected Participant, (A) the reduction of
the exercise price (or strike price) of any outstanding Option or 

  
 2. 








 
SAR under the Plan, (B) the cancellation of any outstanding Option or SAR under the Plan and the grant in substitution therefore of (1) a new Option or SAR under the Plan or another
equity plan of the Company covering the same or a different number of shares of Common Stock, (2) a Restricted Stock Award, (3) a Restricted Stock Unit Award, (4) cash and/or (5) other valuable consideration (as determined by the
Board, in its sole discretion), or (C) any other action that is treated as a repricing under generally accepted accounting principles; provided, however, that no such reduction or cancellation may be effected if it is determined, in the
Company’s sole discretion, that such reduction or cancellation would result in any such outstanding Option becoming subject to the requirements of Section 409A of the Code. 

(c) Delegation to Committee. The Board may delegate some or all of the administration of the Plan to a Committee or Committees. If
administration of the Plan is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee, including the power to
delegate to a subcommittee of the Committee 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. The Board may retain the authority to concurrently administer the Plan with the Committee and may, at any time, revest in the Board some
or all of the powers previously delegated. 
 (d) Effect of Board’s Decision. All determinations, interpretations and
constructions made by the Board in good faith shall not be subject to review by any person and shall be final, binding and conclusive on all persons. 

3. SHARES SUBJECT TO THE PLAN. 

(a) Share Reserve. Subject to the provisions of Section 9(a) relating to Capitalization Adjustments, the aggregate number of shares
of Common Stock that may be issued pursuant to Stock Awards beginning on the Effective Date shall not exceed Three Million Five Hundred Fifty Six Thousand Seven Hundred Eighty Nine (3,556,789) shares (the
“Share Reserve”). Furthermore, if a Stock Award (i) expires or otherwise terminates without having been exercised in full or (ii) is settled in cash (i.e., the holder of the Stock Award receives cash
rather than stock), such expiration, termination or settlement shall not reduce (or otherwise offset) the number of shares of Common Stock that may be issued pursuant to the Plan. For clarity, the limitation in this Section 3(a) is a limitation
in the number of shares of Common Stock that may be issued pursuant to the Plan. Accordingly, this Section 3(a) does not limit the granting of Stock Awards except as provided in Section 7(a). 

(b) Reversion of Shares to the Share Reserve. If any shares of Common Stock issued pursuant to a Stock Award are forfeited back to the
Company because of the failure to meet a contingency or condition required to vest such shares in the Participant, then the shares that are forfeited shall revert to and again become available for issuance under the Plan. Also, any shares reacquired
by the Company pursuant to Section 8(g) or as consideration for the exercise of an Option shall again become available for issuance under the Plan. Notwithstanding the provisions of this Section 3(b), any such shares shall not be
subsequently issued pursuant to the exercise of Incentive Stock Options. 
 (c) Incentive Stock Option Limit. Notwithstanding
anything to the contrary in this Section 3(c), subject to the provisions of Section 9(a) relating to Capitalization Adjustments, the aggregate maximum number of shares of Common Stock that may be issued pursuant to the exercise of
Incentive Stock Options shall be Thirty Five Million Five Hundred Sixty Thousand (35,560,000) shares of Common Stock. 

  
 3. 








 (d) Source of Shares. The stock issuable under the Plan shall be shares of authorized but
unissued or reacquired Common Stock, including shares repurchased by the Company on the open market or otherwise. 
 4. ELIGIBILITY.

 (a) Eligibility for Specific Stock Awards. Incentive Stock Options may be granted only to employees of the Company or a
“parent corporation” or “subsidiary corporation” thereof (as such terms are defined in Sections 424(e) and (f) of the Code). Stock Awards other than Incentive Stock Options may be granted to Employees, Directors and
Consultants; provided, however, Nonstatutory Stock Options and SARs may not be granted to Employees, Directors and Consultants who are providing Continuous Service only to any “parent” of the Company, as such term is defined in
Rule 405, unless the stock underlying such Stock Awards is treated as “service recipient stock” under Section 409A of the Code because the Stock Awards are granted pursuant to a corporate transaction (such as a spin off
transaction) or unless such Stock Awards comply with the distribution requirements of Section 409A of the Code. 
 (b) Ten Percent
Shareholders. A Ten Percent Shareholder shall not be granted an Incentive Stock Option unless the exercise price of such Option is at least one hundred ten percent (110%) of the Fair Market Value on the date of grant and the Option is not
exercisable after the expiration of five (5) years from the date of grant. 
 (c) Consultants. A Consultant shall not be
eligible for the grant of a Stock Award if, at the time of grant, either the offer or the sale of the Company’s securities to such Consultant is not exempt under Rule 701 because of the nature of the services that the Consultant is
providing to the Company, because the Consultant is not a natural person, or because of any other provision of Rule 701, unless the Company determines that such grant need not comply with the requirements of Rule 701 and will satisfy
another exemption under the Securities Act as well as comply with the securities laws of all other relevant jurisdictions. 
 5.
PROVISIONS RELATING TO OPTIONS AND STOCK APPRECIATION RIGHTS. 

Each Option or SAR shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. All Options shall be
separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and, if certificates are issued, a separate certificate or certificates shall be issued for shares of Common Stock purchased on exercise of each type
of Option. If an Option is not specifically designated as an Incentive Stock Option, then the Option shall be a Nonstatutory Stock Option. The provisions of separate Options or SARs need not be identical; provided, however, that each Option
Agreement or Stock Appreciation Right Agreement shall conform to (through incorporation of provisions hereof by reference in the applicable Stock Award Agreement or otherwise) the substance of each of the following provisions: 

(a) Term. Subject to the provisions of Section 4(b) regarding Ten Percent Shareholders, no Option or SAR shall be exercisable
after the expiration of ten (10) years from the date of its grant or such shorter period specified in the Stock Award Agreement. 

(b) Exercise Price. Subject to the provisions of Section 4(b) regarding Incentive Stock Options granted to Ten Percent
Shareholders, the exercise price (or strike price) of each Option or SAR shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option or SAR on the date the Option or SAR is granted.
Notwithstanding the foregoing, an 

  
 4. 








 
Option or SAR may be granted with an exercise price (or strike price) lower than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option or SAR if such
Option or SAR is granted pursuant to an assumption of or substitution for another option or stock appreciation right pursuant to a Corporate Transaction and in a manner consistent with the provisions of Sections 409A and 424(a) of the Code
(whether or not such Stock Awards are Incentive Stock Options). Each SAR will be denominated in shares of Common Stock equivalents. 

(c) Consideration for Options. The purchase price of Common Stock acquired pursuant to the exercise of an Option shall be paid, to the
extent permitted by applicable law and as determined by the Board in its sole discretion, by any combination of the methods of payment set forth below. The Board shall have the authority to grant Options that do not permit all of the following
methods of payment (or otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to utilize a particular method of payment. The permitted methods of payment are as follows: 

(i) by cash, check, bank draft or money order payable to the Company; 

(ii) pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of
the stock subject to the Option, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds; 

(iii) by delivery to the Company (either by actual delivery or attestation) of shares of Common Stock; 

(iv) if the Option is a Nonstatutory Stock Option, by a “net exercise” arrangement pursuant to which the Company will
reduce the number of shares of Common Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; provided, however, that the Company shall accept a cash or
other payment from the Participant to the extent of any remaining balance of the aggregate exercise price not satisfied by such reduction in the number of whole shares to be issued; provided, further, that shares of Common Stock will no
longer be subject to an Option and will not be exercisable thereafter to the extent that (A) shares issuable upon exercise are reduced to pay the exercise price pursuant to the “net exercise,” (B) shares are delivered to the
Participant as a result of such exercise, and (C) shares are withheld to satisfy tax withholding obligations; or 
 (v)
according to a deferred payment or similar arrangement with the Optionholder; provided, however, that interest shall compound at least annually and shall be charged at the minimum rate of interest necessary to avoid (A) the
imputation of interest income to the Company and compensation income to the Optionholder under any applicable provisions of the Code, and (B) the classification of the Option as a liability for financial accounting purposes; or 

(vi) in any other form of legal consideration that may be acceptable to the Board. 

(d) Exercise and Payment of a SAR. To exercise any outstanding Stock Appreciation Right, the Participant must provide written notice of
exercise to the Company in compliance with the provisions of the Stock Appreciation Right Agreement evidencing such Stock Appreciation Right. The appreciation distribution payable on the exercise of a Stock Appreciation Right will be not greater
than an amount equal to the excess of (A) the aggregate Fair Market Value (on the date of the exercise of the Stock Appreciation Right) of a number of shares of Common Stock equal to the number of Common


  
 5. 








 
Stock equivalents in which the Participant is vested under such Stock Appreciation Right, and with respect to which the Participant is exercising the Stock Appreciation Right on such date, over
(B) the strike price that will be determined by the Board at the time of grant of the Stock Appreciation Right. The appreciation distribution in respect to a Stock Appreciation Right may be paid in Common Stock, in cash, in any combination of
the two or in any other form of consideration, as determined by the Board and contained in the Stock Appreciation Right Agreement evidencing such Stock Appreciation Right. 

(e) Transferability of Options and SARs. Except as set forth in this Section 5(e), Options and SARs shall not be transferrable.
The Board may, in its sole discretion, impose additional limitations on the transferability of Options and SARs in the applicable award agreement. 

(i) Restrictions on Transfer. An Option or SAR shall not be transferable except by will or by the laws of descent and distribution and
shall be exercisable during the lifetime of the Participant only by the Participant; provided, however, that the Board may, in its sole discretion, permit transfer of the Option or SAR to such extent as permitted by Rule 701 and in a
manner consistent with applicable tax and securities laws upon the Participant’s request. 
 (ii) Domestic Relations Orders.
Upon receiving written permission from the Board or its duly authorized designee, an Option or SAR may be transferred pursuant to a domestic relations order; provided, however, that if an Option is an Incentive Stock Option, such Option may
be deemed to be a Nonstatutory Stock Option as a result of such transfer. 
 (iii) Beneficiary Designation. Upon receiving written
permission from the Board or its duly authorized designee, the Participant may, by delivering written notice to the Company, in a form provided by or otherwise satisfactory to the Company and any broker designated by the Company to effect Option
exercises, designate a third party who, in the event of the death of the Participant, shall thereafter be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. In the absence of such
a designation, the executor or administrator of the Participant’s estate shall be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. 

(f) Vesting Generally. The total number of shares of Common Stock subject to an Option or SAR may vest and therefore become exercisable
in periodic installments that may or may not be equal. The Option or SAR may be subject to such other terms and conditions on the time or times when it may or may not be exercised (which may be based on the satisfaction of performance goals or other
criteria) as the Board may deem appropriate. The vesting provisions of individual Options or SARs may vary. The provisions of this Section 5(f) are subject to any Option or SAR provisions governing the minimum number of shares of Common Stock
as to which an Option or SAR may be exercised. 
 (g) Termination of Continuous Service. Except as otherwise provided in the
applicable Stock Award Agreement or other agreement between the Participant and the Company, in the event that a Participant’s Continuous Service terminates (other than for Cause or upon the Participant’s death or Disability), the
Participant may exercise his or her Option or SAR (to the extent that the Participant was entitled to exercise such Stock Award as of the date of termination of Continuous Service) but only within such period of time ending on the earlier of
(i) the date three (3) months following the termination of the Participant’s Continuous Service (or such longer or shorter period specified in the Stock Award Agreement, which period shall not be less than
thirty (30) days if necessary to comply with applicable state laws unless such termination is for Cause) or (ii) the expiration of the term of the Option or SAR as set forth in the Stock Award Agreement. If, after termination of
Continuous Service, the Participant does not exercise his or her Option or SAR within the time specified herein or in the Stock Award Agreement (as applicable), the Option or SAR shall terminate. 

  
 6. 








 (h) Extension of Termination Date. Except as otherwise provided in the applicable Stock
Award Agreement or other agreement between the Participant and the Company, if the exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause or upon the Participant’s death or
Disability) would be prohibited at any time solely because the issuance of shares of Common Stock would violate the registration requirements under the Securities Act, then the Option or SAR shall terminate on the earlier of (i) the expiration
of a period of three (3) months after the termination of the Participant’s Continuous Service during which the exercise of the Option or SAR would not be in violation of such registration requirements, or (ii) the expiration of
the term of the Option or SAR as set forth in the Stock Award Agreement. In addition, unless otherwise provided in a Participant’s Award Agreement, if the sale of any Common Stock received upon exercise of an Option or SAR following the
termination of the Participant’s Continuous Service (other than for Cause) would violate the Company’s insider trading policy, then the Option or SAR shall terminate on the earlier of (i) the expiration of a period equal to the
applicable post-termination exercise period after the termination of the Participant’s Continuous Service during which the exercise of the Option or SAR would not be in violation of the Company’s insider trading policy, or (ii) the
expiration of the term of the Option or SAR as set forth in the applicable Stock Award Agreement. 
 (i) Disability of Participant.
Except as otherwise provided in the applicable Stock Award Agreement or other agreement between the Participant and the Company, in the event that a Participant’s Continuous Service terminates as a result of the Participant’s Disability,
the Participant may exercise his or her Option or SAR (to the extent that the Participant was entitled to exercise such Option or SAR as of the date of termination of Continuous Service), but only within such period of time ending on the earlier of
(i) the date twelve (12) months following such termination of Continuous Service (or such longer or shorter period specified in the Stock Award Agreement, which period shall not be less than six (6) months if necessary to
comply with applicable state laws), or (ii) the expiration of the term of the Option or SAR as set forth in the Stock Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR
within the time specified herein or in the Stock Award Agreement (as applicable), the Option or SAR shall terminate. 
 (j) Death of
Participant. Except as otherwise provided in the applicable Stock Award Agreement or other agreement between the Participant and the Company, in the event that (i) a Participant’s Continuous Service terminates as a result of the
Participant’s death, or (ii) the Participant dies within the period (if any) specified in the Stock Award Agreement after the termination of the Participant’s Continuous Service for a reason other than death, then the Option or SAR
may be exercised (to the extent the Participant was entitled to exercise such Option or SAR as of the date of death) by the Participant’s estate, by a person who acquired the right to exercise the Option or SAR by bequest or inheritance or by a
person designated to exercise the Option or SAR upon the Participant’s death, but only within the period ending on the earlier of (i) the date eighteen (18) months following the date of death (or such longer or shorter period
specified in the Stock Award Agreement, which period shall not be less than six (6) months if necessary to comply with applicable state laws), or (ii) the expiration of the term of such Option or SAR as set forth in the Stock Award
Agreement. If, after the Participant’s death, the Option or SAR is not exercised within the time specified herein or in the Stock Award Agreement (as applicable), the Option or SAR shall terminate. 

(k) Termination for Cause. Except as explicitly provided otherwise in a Participant’s Stock Award Agreement, if a
Participant’s Continuous Service is terminated for Cause, the Option or SAR shall 

  
 7. 








 
terminate upon the termination date of such Participant’s Continuous Service, and the Participant shall be prohibited from exercising his or her Option or SAR from and after the time of such
termination of Continuous Service. 
 (l) Non-Exempt Employees. No Option or SAR granted to an Employee who is a non-exempt employee
for purposes of the Fair Labor Standards Act of 1938, as amended, shall be first exercisable for any shares of Common Stock until at least six months following the date of grant of the Option or SAR. Notwithstanding the foregoing, consistent
with the provisions of the Worker Economic Opportunity Act, in the event of the Participant’s death or Disability, upon a Corporate Transaction or a Change in Control in which the vesting of such Options or SARs accelerates, or upon the
Participant’s retirement (as such term may be defined in the Participant’s Stock Award Agreement or in another applicable agreement or in accordance with the Company’s then current employment policies and guidelines) any such vested
Options and SARs may be exercised earlier than six months following the date of grant. The foregoing provision is intended to operate so that any income derived by a non-exempt employee in connection with the exercise or vesting of an Option or SAR
will be exempt from his or her regular rate of pay. 
 (m) Early Exercise of Options. An Option may, but need not, include a
provision whereby the Optionholder may elect at any time before the Optionholder’s Continuous Service terminates to exercise the Option as to any part or all of the shares of Common Stock subject to the Option prior to the full vesting of the
Option. Subject to the “Repurchase Limitation” in Section 8(l), any unvested shares of Common Stock so purchased may be subject to a repurchase right in favor of the Company or to any other restriction the Board determines to be
appropriate. Provided that the “Repurchase Limitation” in Section 8(l) is not violated, the Company shall not be required to exercise its repurchase right until at least six (6) months (or such longer or shorter period
of time required to avoid classification of the Option as a liability for financial accounting purposes) have elapsed following exercise of the Option unless the Board otherwise specifically provides in the Option Agreement. 

(n) Right of Repurchase. Subject to the “Repurchase Limitation” in Section 8(l), the Option or SAR may include a
provision whereby the Company may elect to repurchase all or any part of the vested shares of Common Stock acquired by the Participant pursuant to the exercise of the Option or SAR. 

(o) Right of First Refusal. The Option or SAR may include a provision whereby the Company may elect to exercise a right of first
refusal following receipt of notice from the Participant of the intent to transfer all or any part of the shares of Common Stock received upon the exercise of the Option or SAR. Such right of first refusal shall be subject to the
“Repurchase Limitation” in Section 8(l). Except as expressly provided in this Section 5(o) or in the Stock Award Agreement, such right of first refusal shall otherwise comply with any applicable provisions of the Bylaws of
the Company. 
 6. PROVISIONS OF RESTRICTED STOCK AWARDS AND
RESTRICTED STOCK UNITS. 
 (a) Restricted Stock Awards. Each Restricted Stock Award
Agreement shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. To the extent consistent with the Company’s Bylaws, at the Board’s election, shares of Common Stock may be (x) held in
book entry form subject to the Company’s instructions until any restrictions relating to the Restricted Stock Award lapse; or (y) evidenced by a certificate, which certificate shall be held in such form and manner as determined by the
Board. The terms and conditions of Restricted Stock Award Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Award 

  
 8. 








 
Agreements need not be identical; provided, however, that each Restricted Stock Award Agreement shall conform to (through incorporation of the provisions hereof by reference in the
agreement or otherwise) the substance of each of the following provisions: 
 (i) Consideration. A Restricted Stock Award may be
awarded in consideration for (A) cash or cash equivalents, (B) past services actually rendered to the Company or an Affiliate, or (C) any other form of legal consideration that may be acceptable to the Board in its sole discretion and
permissible under applicable law. 
 (ii) Vesting. Subject to the “Repurchase Limitation” in Section 8(l), shares
of Common Stock awarded under the Restricted Stock Award Agreement may be subject to forfeiture to the Company in accordance with a vesting schedule to be determined by the Board. 

(iii) Termination of Participant’s Continuous Service. If a Participant’s Continuous Service terminates, the Company may
receive through a forfeiture condition or a repurchase right, any or all of the shares of Common Stock held by the Participant that have not vested as of the date of termination of Continuous Service under the terms of the Restricted Stock Award
Agreement. 
 (iv) Transferability. Rights to acquire shares of Common Stock under the Restricted Stock Award Agreement shall be
transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Award Agreement, as the Board shall determine in its sole discretion, so long as Common Stock awarded under the Restricted Stock Award
Agreement remains subject to the terms of the Restricted Stock Award Agreement. 
 (v) Dividends. A Restricted Stock Award Agreement
may provide that any dividends paid on Restricted Stock will be subject to the same vesting and forfeiture restrictions as apply to the shares subject to the Restricted Stock Award to which they relate. 

(b) Restricted Stock Unit Awards. Each Restricted Stock Unit Award Agreement shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. The terms and conditions of Restricted Stock Unit Award Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Unit Award Agreements need not be identical,
provided, however, that each Restricted Stock Unit Award Agreement shall conform to (through incorporation of the provisions hereof by reference in the Agreement or otherwise) the substance of each of the following provisions: 

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

(ii) Vesting. At the time of the grant of a Restricted Stock Unit Award, the Board may impose such restrictions or conditions to the
vesting of the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate. 

  
 9. 








 (iii) Payment. A Restricted Stock Unit Award may be settled by the delivery of shares of
Common Stock, their cash equivalent, any combination thereof or in any other form of consideration, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. 

(iv) Additional Restrictions. At the time of the grant of a Restricted Stock Unit Award, the Board, as it deems appropriate, may impose
such restrictions or conditions that delay the delivery of the shares of Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to a time after the vesting of such Restricted Stock Unit Award. 

(v) Dividend Equivalents. Dividend equivalents may be credited in respect of shares of Common Stock covered by a Restricted Stock Unit
Award, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. At the sole discretion of the Board, such dividend equivalents may be converted into additional shares of Common Stock covered by the Restricted Stock Unit
Award in such manner as determined by the Board. Any additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents will be subject to all the terms and conditions of the underlying Restricted Stock Unit
Award Agreement to which they relate. 
 (vi) Termination of Participant’s Continuous Service. Except as otherwise provided in
the applicable Restricted Stock Unit Award Agreement, such portion of the Restricted Stock Unit Award that has not vested will be forfeited upon the Participant’s termination of Continuous Service. 

(vii) Compliance with Section 409A of the Code. Notwithstanding anything to the contrary set forth herein, any Restricted Stock
Unit Award granted under the Plan that is not exempt from the requirements of Section 409A of the Code shall contain such provisions so that such Restricted Stock Unit Award will comply with the requirements of Section 409A of the Code.
Such restrictions, if any, shall be determined by the Board and contained in the Restricted Stock Unit Award Agreement evidencing such Restricted Stock Unit Award. For example, such restrictions may include, without limitation, a requirement that
any Common Stock that is to be issued in a year following the year in which the Restricted Stock Unit Award vests must be issued in accordance with a fixed pre-determined schedule. 

7. COVENANTS OF THE COMPANY. 

(a) Availability of Shares. During the terms of the Stock Awards, the Company shall keep available at all times the number of shares of
Common Stock reasonably required to satisfy such Stock Awards. 
 (b) Securities Law Compliance. The Company shall seek to obtain
from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock Awards; provided, however, that this
undertaking shall not require the Company to register under the Securities Act the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts, the Company is unable to obtain from any
such regulatory commission or agency the authority that counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell Common
Stock upon exercise of such Stock Awards unless and until such authority is obtained. A Participant shall not be eligible for the grant of a Stock Award or the subsequent issuance of Common Stock pursuant to the Stock Award if such grant or issuance
would be in violation of any applicable securities law. 

  
 10. 








 (c) No Obligation to Notify. The Company shall have no duty or obligation to any
Participant to advise such holder as to the time or manner of exercising such Stock Award. Furthermore, the Company shall have no duty or obligation to warn or otherwise advise such holder of a pending termination or expiration of a Stock Award or a
possible period in which the Stock Award may not be exercised. The Company has no duty or obligation to minimize the tax consequences of a Stock Award to the holder of such Stock Award. 

8. MISCELLANEOUS. 
 (a)
Use of Proceeds from Sales of Common Stock. Proceeds from the sale of shares of Common Stock pursuant to Stock Awards shall constitute general funds of the Company. 

(b) Corporate Action Constituting Grant of Stock Awards. Corporate action constituting a grant by the Company of a Stock Award to any
Participant shall be deemed completed as of the date of such corporate action, unless otherwise determined by the Board, regardless of when the instrument, certificate, or letter evidencing the Stock Award is communicated to, or actually received or
accepted by, the Participant. 
 (c) Shareholder Rights. No Participant shall be deemed to be the holder of, or to have any of the
rights of a holder with respect to, any shares of Common Stock subject to such Stock Award unless and until (i) such Participant has satisfied all requirements for exercise of the Stock Award pursuant to its terms, if applicable, and
(ii) the issuance of the Common Stock subject to such Stock Award has been entered into the books and records of the Company. 
 (d)
No Employment or Other Service Rights. Nothing in the Plan, any Stock Award Agreement or any other instrument executed thereunder or in connection with any Stock Award granted pursuant thereto shall confer upon any Participant any right to
continue to serve the Company or an Affiliate in the capacity in effect at the time the Stock Award was granted or shall affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and
with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate, or (iii) the service of a Director pursuant to the Bylaws of the Company or an Affiliate,
and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be. 

(e) Incentive Stock Option $100,000 Limitation. To the extent that the aggregate Fair Market Value (determined at the time of grant) of
Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and any Affiliates) exceeds one hundred thousand dollars ($100,000), the
Options or portions thereof that exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Option Agreement(s). 

(f) Investment Assurances. The Company may require a Participant, as a condition of exercising or acquiring Common Stock under any
Stock Award, (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 Stock Award; and (ii) to give
written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock 

  
 11. 








 
subject to the Stock Award for the Participant’s own account and not with any present intention of selling or otherwise distributing the Common Stock. The foregoing requirements, and any
assurances given pursuant to such requirements, shall be inoperative if (x) the issuance of the shares upon the exercise or acquisition of Common Stock under the Stock Award has been registered under a then currently effective registration
statement under the Securities Act, or (y) 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 the 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 Common Stock. 
 (g) Withholding Obligations. Unless prohibited by the terms of a Stock Award
Agreement, the Company may, in its sole discretion, satisfy any federal, state or local tax withholding obligation relating to a Stock Award by any of the following means or by a combination of such means: (i) causing the Participant to tender
a cash payment; (ii) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to the Participant in connection with the Stock Award; provided, however, that no shares of Common Stock are withheld
with a value exceeding the minimum amount of tax required to be withheld by law (or such lesser amount as may be necessary to avoid classification of the Stock Award as a liability for financial accounting purposes); (iii) withholding payment
from any amounts otherwise payable to the Participant; (iv) withholding cash from a Stock Award settled in cash; or (v) by such other method as may be set forth in the Stock Award Agreement. 

(h) Electronic Delivery. Any reference herein to a “written” agreement or document shall include any agreement or document
delivered electronically or posted on the Company’s intranet. 
 (i) Deferrals. To the extent permitted by applicable law, the
Board, in its sole discretion, may determine that the delivery of Common Stock or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Stock Award may be deferred and may establish programs and procedures for
deferral elections to be made by Participants. Deferrals by Participants will be made in accordance with Section 409A of the Code. Consistent with Section 409A of the Code, the Board may provide for distributions while a Participant is
still an employee or otherwise providing services to the Company. The Board is authorized to make deferrals of Stock Awards and determine when, and in what annual percentages, Participants may receive payments, including lump sum payments, following
the Participant’s termination of Continuous Service, and implement such other terms and conditions consistent with the provisions of the Plan and in accordance with applicable law. 

(j) Compliance with Section 409A. To the extent that the Board determines that any Stock Award granted hereunder is subject to
Section 409A of the Code, the Stock Award Agreement evidencing such Stock Award shall incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the Code. To the extent applicable, the Plan
and Stock Award Agreements shall be interpreted in accordance with Section 409A of the Code.

five hundred (500), and (ii) the assets of the Company at the end of the Company’s most recently completed fiscal year exceed $10 million, then the following restrictions shall apply during any period during which the
Company does not have a class of its securities registered under Section 12 of the Exchange Act and is not required to file reports under Section 15(d) of the Exchange Act: (A) the Options and, prior to exercise, the shares of


  
 12. 








 
Common Stock acquired upon exercise of the Options may not be transferred until the Company is no longer relying on the exemption provided by Rule 12h-1(f) promulgated under the Exchange Act
(“Rule 12h-1(f)”), except: (1) as permitted by Rule 701(c) promulgated under the Securities Act, (2) to a guardian upon the disability of the Optionholder, or
(3) to an executor upon the death of the Optionholder (collectively, the “Permitted Transferees”); provided, however, the following transfers are permitted: (i) transfers by the Optionholder to the
Company, and (ii) transfers in connection with a change of control or other acquisition involving the Company, if following such transaction, the Options no longer remain outstanding and the Company is no longer relying on the exemption
provided by Rule 12h-1(f); provided further, that any Permitted Transferees may not further transfer the Options; (B) except as otherwise provided in (A) above, the Options and shares of
Common Stock acquired upon exercise of the Options are restricted as to any pledge, hypothecation, or other transfer, including any short position, any “put equivalent position” as defined by
Rule 16a-1(h) promulgated under the Exchange Act, or any “call equivalent position” as defined by Rule 16a-1(b) promulgated under the
Exchange Act by the Optionholder prior to exercise of an Option until the Company is no longer relying on the exemption provided by Rule 12h-1(f); and (C) at any time that the Company is relying on
the exemption provided by Rule 12h-1(f), the Company shall deliver to Optionholders (whether by physical or electronic delivery or written notice of the availability of the information on an internet
site) the information required by Rule 701(e)(3), (4), and (5) promulgated under the Securities Act every six (6) months, including financial statements that are not more than one hundred eighty (180) days old;
provided, however, that the Company may condition the delivery of such information upon the Optionholder’s agreement to maintain its confidentiality. 

(l) Repurchase Limitation. The terms of any repurchase right shall be specified in the Stock Award Agreement. The repurchase price for
vested shares of Common Stock shall be the Fair Market Value of the shares of Common Stock on the date of repurchase. The repurchase price for unvested shares of Common Stock shall be the lower of (i) the Fair Market Value of the shares of
Common Stock on the date of repurchase or (ii) their original purchase price. However, the Company shall not exercise its repurchase right until at least six (6) months (or such longer or shorter period of time necessary to avoid
classification of the Stock Award as a liability for financial accounting purposes) have elapsed following delivery of shares of Common Stock subject to the Stock Award, unless otherwise specifically provided by the Board. 

9. ADJUSTMENTS UPON CHANGES IN COMMON STOCK; OTHER
CORPORATE EVENTS. 
 (a) Capitalization Adjustments. In the event of a Capitalization Adjustment,
the Board shall appropriately and proportionately adjust: (i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities that may be issued pursuant
to the exercise of Incentive Stock Options pursuant to Section 3(c), and (iii) the class(es) and number of securities and price per share of stock subject to outstanding Stock Awards. The Board shall make such adjustments, and its
determination shall be final, binding and conclusive. 
 (b) Dissolution or Liquidation. Except as otherwise provided in the Stock
Award Agreement, in the event of a dissolution or liquidation of the Company, all outstanding Stock Awards (other than Stock Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or the
Company’s right of repurchase) shall terminate immediately prior to the completion of such dissolution or liquidation, and the shares of Common Stock subject to the Company’s repurchase rights or subject to a forfeiture condition may be
repurchased or reacquired by the Company notwithstanding the fact that the holder of such Stock Award is providing Continuous Service, provided, however, that the Board may, in its sole discretion, cause some or all Stock Awards to become
fully 

  
 13. 








 
vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent such Stock Awards have not previously expired or terminated) before the dissolution or liquidation is
completed but contingent on its completion. 
 (c) Corporate Transaction. The following provisions shall apply to Stock Awards in the
event of a Corporate Transaction unless otherwise provided in the instrument evidencing the Stock Award or any other written agreement between the Company or any Affiliate and the holder of the Stock Award or unless otherwise expressly provided by
the Board at the time of grant of a Stock Award. Except as otherwise stated in the Stock Award Agreement, in the event of a Corporate Transaction, then, notwithstanding any other provision of the Plan, the Board shall take one or more of the
following actions with respect to Stock Awards, contingent upon the closing or completion of the Corporate Transaction: 
 (i)
arrange for the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) to assume or continue the Stock Award or to substitute a similar stock award for the Stock Award (including, but not
limited to, an award to acquire the same consideration paid to the shareholders of the Company pursuant to the Corporate Transaction); 

(ii) arrange for the assignment of any reacquisition or repurchase rights held by the Company in respect of Common Stock issued
pursuant to the Stock Award to the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company); 

(iii) accelerate the vesting of the Stock Award (and, if applicable, the time at which the Stock Award may be exercised) to a date
prior to the effective time of such Corporate Transaction as the Board shall determine (or, if the Board shall not determine such a date, to the date that is five (5) days prior to the effective date of the Corporate Transaction), with
such Stock Award terminating if not exercised (if applicable) at or prior to the effective time of the Corporate Transaction; 
 (iv)
arrange for the lapse of any reacquisition or repurchase rights held by the Company with respect to the Stock Award; 
 (v)
cancel or arrange for the cancellation of the Stock Award, to the extent not vested or not exercised prior to the effective time of the Corporate Transaction, in exchange for such cash consideration as the Board, in its sole discretion, may
consider appropriate; and 
 (vi) make a payment, in such form as may be determined by the Board equal to the excess, if any, of
(A) the value of the property the holder of the Stock Award would have received upon the exercise of the Stock Award, over (B) any exercise price payable by such holder in connection with such exercise. 

The Board need not take the same action with respect to all Stock Awards or with respect to all Participants. 

(d) Change in Control. A Stock Award may be subject to additional acceleration of vesting and exercisability upon or after a Change in
Control as may be provided in the Stock Award Agreement for such Stock Award or as may be provided in any other written agreement between the Company or any Affiliate and the Participant, but in the absence of such provision, no such acceleration
shall occur.

restructuring transaction, as that term is used in Statement of Financial Accounting Standards No. 123 (revised)). Notwithstanding the foregoing, the conversion of any convertible securities of the Company shall not be treated as a
Capitalization Adjustment.

Company by an investor, any affiliate thereof or any other Exchange Act Person that acquires the Company’s securities in a transaction or series of related transactions the primary purpose of which is to obtain financing for the Company through
the issuance of equity securities or (C) solely because the level of Ownership held by any Exchange Act Person (the “Subject Person”) exceeds the designated percentage threshold of the outstanding voting securities
as a result of a repurchase or other acquisition of voting securities by the Company reducing the number of shares outstanding, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition
of voting securities by the Company, and after such share acquisition, the Subject Person becomes the Owner of any additional voting securities that, assuming the repurchase or other acquisition had not occurred, increases the percentage of the then
outstanding voting securities Owned by the Subject Person over the designated percentage threshold, then a Change in Control shall be deemed to occur;

the combined voting power of the voting securities of which are Owned by shareholders of the Company in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such sale, lease,
license or other disposition; or

member was approved or recommended by a majority vote of the members of the Incumbent Board then still in office, such new member shall, for purposes of this Plan, be considered as a member of the Incumbent Board. 

  
 16. 








 Notwithstanding the foregoing definition or any other provision of this Plan, (A) the term Change in Control
shall not include a sale of assets, merger or other transaction effected exclusively for the purpose of changing the domicile of the Company, and (B) the definition of Change in Control (or any analogous term) in an individual written agreement
between the Company or any Affiliate and the Participant shall supersede the foregoing definition with respect to Stock Awards subject to such agreement; provided, however, that if no definition of Change in Control or any analogous term is

(k) “Continuous Service” means that the Participant’s service with the Company or an Affiliate, whether as
an Employee, Director or Consultant, is not interrupted or terminated. A change in the capacity in which the Participant renders service to the Company or an Affiliate as an Employee, Director, or Consultant or a change in the Entity for which the
Participant renders such service, provided that there is no interruption or termination of the Participant’s service with the Company or an Affiliate, shall not terminate a Participant’s Continuous Service; provided, however, if the
Entity for which a Participant is rendering service ceases to qualify as an Affiliate, as determined by the Board in its sole discretion, such Participant’s Continuous Service shall be considered to have terminated on the date such Entity
ceases to qualify as an Affiliate. For example, a change in status from an employee of the Company to a consultant of an Affiliate or to a Director shall not constitute an interruption of Continuous Service. To the extent permitted by law, the Board
or the chief executive officer of the Company, in that party’s sole discretion, may determine whether Continuous Service shall be considered interrupted in the case of (i) any leave of absence approved by the Board or chief executive
officer, including sick leave, military leave or any other personal leave, or (ii) transfers between the Company, an Affiliate, or their successors. Notwithstanding the foregoing, a leave of absence shall be treated as Continuous Service for
purposes of vesting in a Stock Award only to such extent as may be provided in the Company’s leave of absence policy, in the written terms of any leave of absence agreement or policy applicable to the Participant, or as otherwise required by
law.

the Company or an Affiliate prior to the Date of Grant with respect to which such options are exercisable for the first time during the same calendar year, shall not exceed $100,000 (the
“ISO Exercise Limitation”) unless applicable law requires that your option be exercisable sooner. For purposes of this Section 4, your options designated as Incentive Stock Options shall be taken into account in the
order in which they were granted to you, and the Fair Market Value of shares of Common Stock shall be determined as of the time the option with respect to such shares of Common Stock is granted. If Section 422 of the Code is amended to provide
for a different limitation from that set forth in this provision, the ISO Exercise Limitation shall be deemed amended effective as of the date required or permitted by such amendment to the Code. 

(b) Notwithstanding the provisions of Section 4(a), if the ISO Exercise Limitation would prevent you from exercising your option
as to vested shares, then the ISO Exercise Limitation shall terminate as to such vested shares as such shares vest, and you may exercise your option as to such vested shares. Upon such termination of the ISO Exercise Limitation, your option shall be
deemed a Nonstatutory Stock Option to the extent of the number of vested shares of Common Stock subject to your option that exceed the ISO Exercise Limitation. 

(c) The ISO Exercise Limitation shall terminate, and you may fully exercise your option, as to all vested shares of Common Stock
subject to your option, upon the earlier of the following events: 
 (i) the date of termination of your Continuous Service; 

(ii) the day immediately prior to the effective date of a Corporate Transaction; or 

(iii) the day that is ten (10) days prior to the Expiration Date of your option. 

Upon such termination of the ISO Exercise Limitation, your option shall be deemed a Nonstatutory Stock Option to the extent of the number of shares of Common
Stock subject to your option that exceed the ISO Exercise Limitation. 
 5. EXERCISE PRIOR
TO VESTING (“EARLY EXERCISE”). If permitted in your Grant Notice (i.e., the “Exercise Schedule” indicates “Early Exercise Permitted”) and subject to
the provisions of your option, you may elect at any time that is both (i) during the period of your Continuous Service and (ii) during the term of your option, to exercise all or part of your option, including the unvested portion of your
option; provided, however, that: 
 (a) a partial exercise of your option shall be deemed to cover first vested shares of
Common Stock and then the earliest vesting installment of unvested shares of Common Stock; 
 (b) any shares of Common Stock so
purchased from installments that have not vested as of the date of exercise shall be subject to the purchase option in favor of the Company as described in the Company’s form of Early Exercise Stock Purchase Agreement; 

  
 2. 








 (c) you shall enter into the Company’s form of Early Exercise Stock Purchase
Agreement with a vesting schedule that will result in the same vesting as if no early exercise had occurred; and 
 (d) if your
option is an Incentive Stock Option, then, to the extent that the aggregate Fair Market Value (determined at the time of grant) of the shares of Common Stock with respect to which your option plus all other Incentive Stock Options you hold are
exercisable for the first time by you during any calendar year (under all plans of the Company and its Affiliates) exceeds one hundred thousand dollars ($100,000), your option(s) or portions thereof that exceed such limit (according to the order in
which they were granted) shall be treated as Nonstatutory Stock Options. 
 6. METHOD OF
PAYMENT. Payment of the exercise price is due in full upon exercise of all or any part of your option. You may elect to make payment of the exercise price in cash or by check or in any other manner permitted by your Grant
Notice, which may include one or more of the following: 
 (a) Provided that at the time of exercise the Common Stock is
publicly traded and quoted regularly in The Wall Street Journal, pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or
check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds. 

(b) Provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, by
delivery to the Company (either by actual delivery or attestation) of already-owned shares of Common Stock that are owned free and clear of any liens, claims, encumbrances or security interests, and that are valued at Fair Market Value on the date
of exercise. Notwithstanding the foregoing, you may not exercise your option by tender to the Company of Common Stock to the extent such tender would violate the provisions of any law, regulation or agreement restricting the redemption of the
Company’s stock. 
 (c) If permitted in your Grant Notice, pursuant to the following deferred payment alternative: 

(i) Not less than one hundred percent (100%) of the aggregate exercise price, plus accrued interest, shall be due four
(4) years from date of exercise or, at the Company’s election, upon termination of your Continuous Service. 
 (ii)
Interest shall be compounded at least annually and shall be charged at the minimum rate of interest necessary to avoid (1) the treatment as interest, under any applicable provisions of the Code, of any amounts other than amounts stated to be
interest under the deferred payment arrangement and (2) the classification of your option as a liability for financial accounting purposes. 

(iii) In order to elect the deferred payment alternative, you must, as a part of your written notice of exercise, give notice of the
election of this payment alternative and, in order to secure the payment of the deferred exercise price to the Company hereunder, if the 

  
 3. 








 
Company so requests, you must tender to the Company a promissory note and a pledge agreement covering the purchased shares of Common Stock, both in form and substance satisfactory to the Company,
or such other or additional documentation as the Company may request. 
 7. WHOLE SHARES. You may
exercise your option only for whole shares of Common Stock. 
 8. SECURITIES LAW
COMPLIANCE. Notwithstanding anything to the contrary contained herein, you may not exercise your option unless the shares of Common Stock issuable upon such exercise are then registered under the Securities Act or, if such shares
of Common Stock are not then so registered, the Company has determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act. The exercise of your option also must comply with other applicable laws
and regulations governing your option, and you may not exercise your option if the Company determines that such exercise would not be in material compliance with such laws and regulations. 

9. TERM. You may not exercise your option before the commencement of its term or after its term expires. The term of
your option commences on the Date of Grant and expires upon the earliest of the following: 
 (a) immediately upon the termination of
your Continuous Service for Cause; 
 (b) three (3) months after the termination of your Continuous Service for any reason other
than Cause, Disability or death, provided that if during any part of such three (3)-month period you may not exercise your option solely because of the condition set forth in the preceding paragraph relating to “Securities Law Compliance,”
your option shall not expire until the earlier of the Expiration Date or until it shall have been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service; 

(c) twelve (12) months after the termination of your Continuous Service due to your Disability; 

(d) eighteen (18) months after your death if you die either during your Continuous Service or within three (3) months after
your Continuous Service terminates for any reason other than Cause; 
 (e) the Expiration Date indicated in your Grant Notice; or

 (f) the day before the tenth (10th) anniversary of the Date of Grant. 

“Cause” means the occurrence of any one or more of the following: (i) your commission of any crime
involving fraud, dishonesty or moral turpitude; (ii) your attempted commission of or participation in a fraud or act of dishonesty against the Company that results in (or might have reasonably resulted in) material harm to the business of the
Company; (iii) your intentional, material violation of any contract or agreement between you and the Company or any statutory duty you owe to the Company; or (iv) your conduct that constitutes gross insubordination, incompetence or
habitual neglect of duties and that results in (or might have reasonably resulted  

  
 4. 








 
in) material harm to the business of the Company; provided, however, that the action or conduct described in clauses (iii) and (iv) above will constitute “Cause” only if such
action or conduct continues after the Company has provided you with written notice thereof and thirty (30) days to cure the same. 
 If
your option is an Incentive Stock Option, note that to obtain the federal income tax advantages associated with an Incentive Stock Option, the Code requires that at all times beginning on the date of grant of your option and ending on the day three
(3) months before the date of your option’s exercise, you must be an employee of the Company or an Affiliate, except in the event of your death or Disability. The Company has provided for extended exercisability of your option under
certain circumstances for your benefit but cannot guarantee that your option will necessarily be treated as an Incentive Stock Option if you continue to provide services to the Company or an Affiliate as a Consultant or Director after your
employment terminates or if you otherwise exercise your option more than three (3) months after the date your employment with the Company or an Affiliate terminates. 

10. EXERCISE. 

(a) You may exercise the vested portion of your option (and the unvested portion of your option if your Grant Notice so permits) during
its term by delivering a Notice of Exercise (in a form designated by the Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with
such additional documents as the Company may then require. 
 (b) By exercising your option you agree that, as a condition to any
exercise of your option, the Company may require you to enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (1) the exercise of your option,
(2) the lapse of any substantial risk of forfeiture to which the shares of Common Stock are subject at the time of exercise, or (3) the disposition of shares of Common Stock acquired upon such exercise. 

(c) If your option is an Incentive Stock Option, by exercising your option you agree that you will notify the Company in writing within
fifteen (15) days after the date of any disposition of any of the shares of the Common Stock issued upon exercise of your option that occurs within two (2) years after the date of your option grant or within one (1) year after such
shares of Common Stock are transferred upon exercise of your option. 
 (d) By exercising your option you agree that you shall not
sell, dispose of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any shares of Common Stock or other securities of the Company held by
you, for a period of one hundred eighty (180) days following the effective date of a registration statement of the Company filed under the Securities Act or such longer period as necessary to permit compliance with NASD Rule 2711 or NYSE Member
Rule 472 and similar rules and regulations (the “Lock-Up Period”); provided, however, that nothing contained in this section shall prevent the exercise of a repurchase option, if any, in favor of the Company during the
Lock-Up Period. You further agree to execute and deliver such other agreements as may be reasonably requested by the Company and/or the underwriter(s) that 

  
 5. 








 
are consistent with the foregoing or that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect
to your shares of Common Stock until the end of such period. The underwriters of the Company’s stock are intended third party beneficiaries of this Section 9(d) and shall have the right, power and authority to enforce the provisions hereof
as though they were a party hereto. 
 11. TRANSFERABILITY. Your option is not transferable, except by will or by the
laws of descent and distribution, and is exercisable during your life only by you. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in the event
of your death, shall thereafter be entitled to exercise your option. In addition, if permitted by the Company you may transfer your option to a trust if you are considered to be the sole beneficial owner (determined under Section 671 of the
Code and applicable state law) while the option is held in the trust, provided that you and the trustee enter into a transfer and other agreements required by the Company. 

12. RIGHT OF FIRST REFUSAL. Shares of Common Stock that you acquire upon
exercise of your option are subject to any right of first refusal that may be described in the Company’s bylaws in effect at such time the Company elects to exercise its right; provided, however, that if your option is an Incentive Stock
Option and the right of first refusal described in the Company’s bylaws in effect at the time the Company elects to exercise its right is more beneficial to you than the right of first refusal described in the Company’s bylaws on the Date
of Grant, then the right of first refusal described in the Company’s bylaws on the Date of Grant shall apply. The Company’s right of first refusal shall expire on the first date upon which any security of the Company is listed (or approved
for listing) upon notice of issuance on a national securities exchange or quotation system. 
 13. RIGHT OF
REPURCHASE. To the extent provided in the Company’s bylaws in effect at such time the Company elects to exercise its right, the Company shall have the right to repurchase all or any part of the shares of Common Stock you
acquire pursuant to the exercise of your option. 
 14. OPTION NOT A SERVICE
CONTRACT. Your option is not an employment or service contract, and nothing in your option shall be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an Affiliate, or of
the Company or an Affiliate to continue your employment. In addition, nothing in your option shall obligate the Company or an Affiliate, their respective shareholders, Boards of Directors, Officers or Employees to continue any relationship that you
might have as a Director or Consultant for the Company or an Affiliate. 
 15. WITHHOLDING OBLIGATIONS.

 (a) At the time you exercise your option, in whole or in part, or at any time thereafter as requested by the Company, you hereby
authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “cashless exercise” pursuant to a program developed under Regulation T as promulgated by
the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with the exercise of
your option. 

  
 6. 








 (b) Upon your request and subject to approval by the Company, in its sole discretion, and
compliance with any applicable legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole shares of Common Stock having a Fair
Market Value, determined by the Company as of the date of exercise, not in excess of the minimum amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid classification of your option as a liability for
financial accounting purposes). If the date of determination of any tax withholding obligation is deferred to a date later than the date of exercise of your option, share withholding pursuant to the preceding sentence shall not be permitted unless
you make a proper and timely election under Section 83(b) of the Code, covering the aggregate number of shares of Common Stock acquired upon such exercise with respect to which such determination is otherwise deferred, to accelerate the
determination of such tax withholding obligation to the date of exercise of your option. Notwithstanding the filing of such election, shares of Common Stock shall be withheld solely from fully vested shares of Common Stock determined as of the date
of exercise of your option that are otherwise issuable to you upon such exercise. Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility. 

(c) You may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate are satisfied.
Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company shall have no obligation to issue a certificate for such shares of Common Stock or release such shares of Common Stock from any
escrow provided for herein unless such obligations are satisfied. 
 16. TAX CONSEQUENCES. You hereby
agree that the Company does not have a duty to design or administer the Plan or its other compensation programs in a manner that minimizes your tax liabilities. You shall not make any claim against the Company, or any of its Officers, Directors,
Employees or Affiliates related to tax liabilities arising from your option or your other compensation. In particular, you acknowledge that this option is exempt from Section 409A of the Code only if the exercise price per share specified in
the Grant Notice is at least equal to the “fair market value” per share of the Common Stock on the Date of Grant and there is no other impermissible deferral of compensation associated with the option. Because the Common Stock is not
traded on an established securities market, the Fair Market Value is determined by the Board, perhaps in consultation with an independent valuation firm retained by the Company. You acknowledge that there is no guarantee that the Internal Revenue
Service will agree with the valuation as determined by the Board, and you shall not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates in the event that the Internal Revenue Service asserts that the
valuation determined by the Board is less than the “fair market value” as subsequently determined by the Internal Revenue Service. 

17. NOTICES. Any notices provided for in your option or the Plan shall be given in writing and shall be deemed
effectively given upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address you provided to the Company. 

  
 7. 








 18. GOVERNING PLAN DOCUMENT. Your option is
subject to all the provisions of the Plan, the provisions of which are hereby made a part of your option, and is further subject to all interpretations, amendments, rules and regulations, which may from time to time be promulgated and adopted
pursuant to the Plan. In the event of any conflict between the provisions of your option and those of the Plan, the provisions of the Plan shall control.

similar transaction with the same economic effect as a sale, any shares of Common Stock or other securities of the Company for a period of one hundred eighty (180) days following the effective date of a registration statement of the Company

deliver such other agreements as may be reasonably requested by the Company and/or the underwriter(s) that are consistent with the foregoing or that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the
Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such period.
