	1.	 GENERAL. 

(a) Successor to Prior Plan. This Plan is the successor to the 89Bio Ltd. 2018 Equity Incentive Plan, as amended and together with any
attachments thereto (the “Prior Plan”). From and after 12:01 a.m. Eastern time on the Effective Date, no additional stock awards will be granted under the Prior Plan. In addition, all stock awards granted under the Prior Plan prior
to the Effective Date that remain outstanding on the Effective Date shall be cancelled and replaced with equivalent Awards under this Plan. All Awards granted on or after 12:01 a.m. Eastern Time on the Effective Date are subject to the terms of this
Plan. 
 (b) Eligible Award Recipients. Employees, Directors and Consultants are eligible to receive Awards. 

(c) Available Awards. This Plan provides for the grant of the following Awards: (i) Incentive Stock Options; (ii) Nonstatutory
Stock Options; (iii) Stock Appreciation Rights; (iv) Restricted Stock Awards; (v) Restricted Stock Unit Awards; (vi) Performance Stock Awards; and (vii) Performance Cash Awards. 

(d) Purpose. This Plan, through the granting of Awards, is intended to help the Company secure and retain the services of eligible award
recipients, provide incentives for such persons to exert maximum efforts for the success of the Company and any Affiliate and provide a means by which the eligible award recipients may benefit from increases in the value of the Common Stock. 

 

	2.	 ADMINISTRATION. 

(a) Administration by Board. The Board will administer this Plan. The Board may delegate administration of this Plan to a Committee or
Committees, as provided in Section 2(c). 
 (b) Powers of Board. The Board will have the power, subject to,
and within the limitations of, the express provisions of this Plan: 
 (i) To determine: (A) who will be granted Awards; (B) when
and how each Award will be granted; (C) what type of Award will be granted; (D) the provisions of each Award (which need not be identical), including when a person will be permitted to exercise or otherwise receive cash or Common Stock
under the Award; (E) the number of shares of Common Stock subject to, or the cash value of, an Award; and (F) the Fair Market Value applicable to a Stock Award. 

 (ii) To construe and interpret this Plan and Awards granted under it, and to establish,
amend and revoke rules and regulations for administration of this Plan and Awards. The Board, in the exercise of these powers, may correct any defect, omission or inconsistency in this Plan or in any Award Document or in the written terms of a
Performance Cash Award, in a manner and to the extent it will deem necessary or expedient to make this Plan or Award fully effective. 

(iii) To settle all controversies regarding this Plan and Awards granted under it. 

(iv) To accelerate, in whole or in part, or to extend, in whole or in part, the time during which an Award may be exercised or vest, or at
which cash or shares of Common Stock may be issued. 
 (v) To suspend or terminate this Plan at any time. Except as otherwise provided in
this Plan or an Award Document, suspension or termination of this Plan will not materially impair a Participant’s rights under his or her then-outstanding Award without his or her written consent except as provided in subsection
(viii) below. 
 (vi) To amend this Plan in any respect the Board deems necessary or advisable, including, without limitation, adopting
amendments relating to Incentive Stock Options and nonqualified deferred compensation under Section 409A of the Code and/or making this Plan or Awards granted under this Plan exempt from or compliant with the requirements for Incentive Stock
Options or exempt from or compliant with the requirements for nonqualified deferred compensation under Section 409A of the Code, subject to the limitations, if any, of applicable law. If required by applicable law or listing requirements, and
except as provided in Section 9(a) relating to Capitalization Adjustments, the Company will seek stockholder approval of any amendment of this Plan that (A) materially increases the number of shares of Common Stock
available for issuance under this Plan, (B) materially expands the class of individuals eligible to receive Awards under this Plan, (C) materially increases the benefits accruing to Participants under this Plan, (D) materially reduces
the price at which shares of Common Stock may be issued or purchased under this Plan, (E) materially extends the term of this Plan, or (F) materially expands the types of Awards available for issuance under this Plan. Except as otherwise
provided in this Plan (including subsection (viii) below) or an Award Document, no amendment of this Plan will materially impair a Participant’s rights under an outstanding Award without the Participant’s written consent. 

(vii) To submit any amendment to this Plan for stockholder approval, including, but not limited to, amendments to this Plan intended to satisfy
the requirements of (A) Section 422 of the Code regarding “incentive stock options” or (B) Rule 16b-3 of the Exchange Act or any successor rule, if applicable. 

  
 2 

 (viii) To approve forms of Award Documents for use under this Plan and to amend the terms of
any one or more outstanding Awards, including, but not limited to, amendments to provide terms more favorable to the Participant than previously provided in the Award Documents for such Awards, subject to any specified limits in this Plan that are
not subject to Board discretion. A Participant’s rights under any Award will not be impaired by any such amendment unless the Company requests the consent of the affected Participant, and the Participant consents in writing. However, a
Participant’s rights will not be deemed to have been impaired by any such amendment if the Board, in its sole discretion, determines that the amendment, taken as a whole, does not materially impair the Participant’s rights. In addition,
subject to the limitations of applicable law, if any, the Board may amend the terms of any one or more Awards without the affected Participant’s consent (A) to maintain the qualified status of the Award as an Incentive Stock Option under
Section 422 of the Code, (B) to change the terms of an Incentive Stock Option, if such change results in impairment of the Award solely because it impairs the qualified status of the Award as an Incentive Stock Option under
Section 422 of the Code, (C) to clarify the manner of exemption from, or to bring the Award into compliance with, Section 409A of the Code, or (D) to comply with other applicable laws or listing requirements. 

(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 this Plan and/or Award Documents. 
 (x) To adopt such procedures and sub-plans as are necessary or appropriate (A) to permit or facilitate participation in this Plan by persons eligible to receive Awards under this Plan who are not citizens of, subject to taxation by, or
employed outside, the United States or (B) to allow Awards to qualify for special tax treatment in a jurisdiction other than the United States. Board approval will not be necessary for immaterial modifications to this Plan or any Award Document
that are required for compliance with the laws of the relevant jurisdiction. 
 (xi) To effect, with the consent of any adversely affected
Participant, (A) the reduction of the exercise, purchase or strike price of any outstanding Stock Award; (B) the cancellation of any outstanding Stock Award and the grant in substitution therefore of a new (1) Option or SAR,
(2) Restricted Stock Award, (3) Restricted Stock Unit Award, (4) cash award and/or (5) award of other valuable consideration determined by the Board, in its sole discretion, with any such substituted award (x) covering the
same or a different number of shares of Common Stock as the cancelled Stock Award and (y) granted under this Plan or another equity or compensatory plan of the Company; or (C) any other action that is treated as a repricing under generally
accepted accounting principles. 
 (c) Delegation to Committee. 

(i) General. The Board may delegate some or all of the administration of this Plan to a Committee or Committees. If administration of
this Plan is delegated to a Committee, the Committee will have, in connection with the administration of this 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 will thereafter be to the Committee or subcommittee). Any delegation of administrative powers will be
reflected in the charter of the Committee to which the delegation is made, or resolutions, not inconsistent with the provisions of this Plan, adopted from time to time by the Board or Committee (as applicable). The Committee may, at any time,
abolish the subcommittee and/or revest in the Committee any powers delegated 

  
 3 

 
to any subcommittee. Unless otherwise provided by the Board, delegation of authority by the Board to a Committee, or to an Officer or employee pursuant to Section 2(d),
does not limit the authority of the Board, which may continue to exercise any authority so delegated and may concurrently administer this Plan with the Committee and may, at any time, revest in the Board some or all of the powers previously
delegated. 
 (ii) Rule 16b-3 Compliance. The Committee may consist solely of two or more Non-Employee Directors, in accordance with Rule 16b-3 of the Exchange Act. 

(d) Delegation to an Officer. The Board may delegate to one (1) or more Officers the authority to do one or both of the following,
to the maximum extent permitted by applicable law: (i) designate Employees who are not Officers to be recipients of Stock Awards and the terms of such Stock Awards; and (ii) determine the number of shares of Common Stock to be subject to
such Stock Awards granted to such Employees; provided, however, that the Board resolutions regarding such delegation will specify the total number of shares of Common Stock that may be subject to the Stock Awards granted by such Officer and that
such Officer may not grant a Stock Award to himself or herself. Any such Stock Awards will be granted on a form that is substantially the same as the form of Stock Award Document approved by the Committee or the Board for use in connection with such
Stock Awards, unless otherwise provided for in the resolutions approving the delegation authority. 
 (e) Effect of Board’s
Decision. All determinations, interpretations and constructions made by the Board (or a duly authorized Committee, subcommittee or Officer exercising powers delegated by the Board under this Section 2) in good faith
will not be subject to review by any person and will be final, binding and conclusive on all persons. 
  

	3.	 SHARES SUBJECT TO THIS PLAN. 

(a) Share Reserve. 
 (i)
Subject to Section 9(a) relating to Capitalization Adjustments, the aggregate maximum number of shares of Common Stock that may be issued pursuant to Stock Awards from and after the Effective Date will not exceed 2,844,193
shares of Common Stock (the “Share Reserve”) plus any shares of Common Stock added as a result of the “evergreen” provision in Section 3(a)(ii). 

(ii) The Share Reserve will automatically increase on January 1st of each year beginning in 2020 and ending with a final increase on
January 1, 2029, in an amount equal to four percent (4%) of the total number of shares of Capital Stock outstanding on December 31st of the preceding calendar year. The Board may provide that there will be no January 1st increase in the Share
Reserve for any such year or that the increase in the Share Reserve for any such year will be a smaller number of shares of Common Stock than would otherwise occur pursuant to the preceding sentence. 

(iii) For clarity, the Share Reserve is a limitation on the number of shares of Common Stock that may be issued under this Plan. As a single
share may be subject to grant more than once (e.g., if a share subject to a Stock Award is forfeited, it may be made subject to grant again as provided in Section 3(b) below), the Share Reserve is not a limit on the number
of Stock Awards that can be granted. 

  
 4 

 (iv) Shares may be issued under the terms of this Plan in connection with a merger or
acquisition as permitted by NASDAQ Listing Rule 5635(c), NYSE Listed Company Manual Section 303A.08, AMEX Company Guide Section 711 or other applicable rule, and such issuance will not reduce the number of shares available for issuance
under this Plan. 
 (b) Reversion of Shares to the Share Reserve. If a Stock Award or any portion of a Stock Award (i) expires,
is cancelled or forfeited or otherwise terminates without all of the shares covered by the Stock Award having been issued or (ii) is settled in cash (i.e., the Participant receives cash rather than stock), such expiration, cancellation,
forfeiture, termination or settlement will not reduce (or otherwise offset) the number of shares of Common Stock that are available for issuance under this Plan. If any shares of Common Stock issued under a Stock Award are forfeited back to,
reacquired at no cost by, or repurchased at cost by 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, reacquired or repurchased will revert to
and again become available for issuance under this Plan. Any shares retained and not issued by the Company in satisfaction of tax withholding obligations on a Stock Award or as consideration for the exercise or purchase price of a Stock Award will
not reduce (or otherwise offset) the number of shares of Common Stock that are available for issuance under this Plan. Any shares reacquired by the Company (as distinguished from being retained without issuance by the Company) in satisfaction of tax
withholding obligations on a Stock Award, as consideration for the exercise or purchase price of a Stock Award, or with the proceeds paid by the Participant under the terms of a Stock Award, will again become available for issuance under this Plan,
but only if such reacquisition occurs during the period beginning on the Effective Date and ending on the tenth (10th) anniversary of the date on which the Company’s stockholders initially
approved this Plan. 
 (c) Incentive Stock Option Limit. Subject to Section 9(a) relating to Capitalization
Adjustments, the aggregate maximum number of shares of Common Stock that may be issued on the exercise of Incentive Stock Options will be 2,844,193 shares of Common Stock. 

(d) Source of Shares. The stock issuable under this Plan will be shares of authorized but unissued or reacquired Common Stock, including
shares repurchased by the Company on the open market or otherwise or shares classified as treasury shares. 
  

	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 424(f) of the Code). Stock Awards other than Incentive Stock Options may be granted to Employees, Directors and Consultants. 

(b) Ten Percent Stockholders. A Ten Percent Stockholder will not be granted an Incentive Stock Option unless the exercise price of such
Option is at least 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. 

  
 5 

	5.	 PROVISIONS RELATING TO OPTIONS AND STOCK APPRECIATION RIGHTS. 

Each Option or SAR will be in such form and will contain such terms and conditions as the Board deems appropriate. All Options will 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 will 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, or if an Option is designated as an Incentive Stock Option but some portion or all of the Option fails to qualify as an Incentive Stock Option under the applicable
rules, then the Option (or portion thereof) will be a Nonstatutory Stock Option. The provisions of separate Options or SARs need not be identical; provided, however, that each Award Document will conform to (through incorporation of provisions
hereof by reference in the applicable Award Document or otherwise) the substance of each of the following provisions: 
 (a) Term.
Subject to Section 4(b) regarding Ten Percent Stockholders, no Option or SAR will be exercisable after the expiration of 10 years from the date of its grant or such shorter period specified in the Award Document. 

(b) Exercise Price. Subject to Section 4(b) regarding Ten Percent Stockholders, the exercise or strike price
of each Option or SAR will be not less than 100% of the Fair Market Value of the Common Stock subject to the Option or SAR on the date the Award is granted. Notwithstanding the foregoing, an Option or SAR may be granted with an exercise or strike
price lower than 100% of the Fair Market Value of the Common Stock subject to the Award if such Award 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 Section 409A of the Code and, if applicable, Section 424(a) of the Code (including, but not limited to, Options or SARs issued in substitution for awards outstanding under the Prior Plan on the
Effective Date). Each SAR will be denominated in shares of Common Stock equivalents. 
 (c) Purchase Price for Options. The purchase
price of Common Stock acquired pursuant to the exercise of an Option may 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 will 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 use a particular
method of payment. The purchase price shall be denominated in U.S. dollars. 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
United States Federal Reserve Board or a successor regulation, or a similar rule in a foreign jurisdiction of domicile of a Participant, that, prior to or contemporaneously with 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 proceeds of sale of such stock; 

  
 6 

 (iii) by delivery to the Company (either by actual delivery or attestation) of shares of
Common Stock; 
 (iv) 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 will accept 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. 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 used 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) in any other form of legal consideration that may be acceptable to the Board and specified in the
applicable Award Document. 
 (d) Exercise and Payment of a SAR. To exercise any outstanding SAR, the Participant must provide written
notice of exercise to the Company in compliance with the provisions of the Stock Appreciation Right Award Document evidencing such SAR. The appreciation distribution payable on the exercise of a SAR 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 SAR) of a number of shares of Common Stock equal to the number of Common Stock equivalents in which the Participant is vested under such SAR (with respect to
which the Participant is exercising the SAR on such date), over (B) the aggregate strike price of the number of Common Stock equivalents with respect to which the Participant is exercising the SAR on such date. The appreciation distribution 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 Award Document evidencing such SAR. 

(e) Transferability of Options and SARs. The Board may, in its sole discretion, impose such limitations on the transferability of
Options and SARs as the Board determines. In the absence of such a determination by the Board to the contrary, the following restrictions on the transferability of Options and SARs will apply: 

(i) Restrictions on Transfer. An Option or SAR will not be transferable except by will or by the laws of descent and distribution (or
pursuant to subsections (ii) and (iii) below), and will be exercisable during the lifetime of the Participant only by the Participant. The Board may permit transfer of the Option or SAR in a manner that is not prohibited by applicable tax and
securities laws. Except as explicitly provided herein, neither an Option nor a SAR may be transferred for consideration. 
 (ii) Domestic
Relations Orders. Subject to the approval of the Board or a duly authorized Officer, an Option or SAR may be transferred pursuant to the terms of a domestic relations order, official marital settlement agreement or other divorce or separation
instrument as permitted by U.S. Treasury Regulation 1.421-1(b)(2) or other applicable law. 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. 

  
 7 

 (iii) Beneficiary Designation. Subject to the approval of the Board or a duly
authorized Officer, a Participant may, by delivering written notice to the Company, in a form approved by the Company (or the designated broker), designate a third party who, on the death of the Participant, will 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 will be entitled to exercise the Option or SAR
and receive the Common Stock or other consideration resulting from such exercise. However, the Company may prohibit designation of a beneficiary at any time, including due to any conclusion by the Company that such designation would be inconsistent
with the provisions of applicable laws. 
 (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 Award Document, or other agreement between the Participant and the Company, if a Participant’s Continuous Service terminates (other than for Cause and other than 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 Award as of the date of termination of Continuous Service) within the period of time
ending on the earlier of (i) the date three (3) months following the termination of the Participant’s Continuous Service and (ii) the expiration of the term of the Option or SAR as set forth in the applicable Award Document. If,
after termination of Continuous Service, the Participant does not exercise his or her Option or SAR within the applicable time frame, the Option or SAR will terminate. 

(h) Extension of Termination Date. Except as otherwise provided in the applicable Award Document, 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 and other than 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 will terminate on the earlier of (i) the expiration of a total period of three
(3) months (that need not be consecutive) 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, and (ii) the
expiration of the term of the Option or SAR as set forth in the applicable Award Document. In addition, unless otherwise provided in a Participant’s applicable Award Document, or other agreement between the Participant and the Company, if the
sale of any Common Stock received upon exercise of an 

  
 8 

 
Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause) would violate the Company’s insider trading policy, and the Company does not waive
the potential violation of the policy or otherwise permit the sale, or allow the Participant to surrender shares of Common Stock to the Company in satisfaction of any exercise price and/or any withholding obligations under
Section 9(h), then the Option or SAR will terminate on the earlier of (i) the expiration of a period of months (that need not be consecutive) equal to the applicable post-termination exercise period after the
termination of the Participant’s Continuous Service during which the sale of the Common Stock received upon 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 Award Document. 
 (i) Disability of Participant. Except as otherwise
provided in the applicable Award Document, or other agreement between the Participant and the Company, if 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 12 months following
such termination of Continuous Service, and (ii) the expiration of the term of the Option or SAR as set forth in the applicable Award Document. If, after termination of Continuous Service, the Participant does not exercise his or her Option or
SAR within the applicable time frame, the Option or SAR (as applicable) will terminate. 
 (j) Death of Participant. Except as
otherwise provided in the applicable Award Document, or other agreement between the Participant and the Company, if (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 this Plan or the applicable Award Document, or other agreement between the Participant and the Company, for exercisability 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 18 months following the date of death, and
(ii) the expiration of the term of such Option or SAR as set forth in the applicable Award Document. If, after the Participant’s death, the Option or SAR is not exercised within the applicable time frame, the Option or SAR will terminate.

 (k) Termination for Cause. Except as explicitly provided otherwise in a Participant’s Award Document or other individual
written agreement between the Company or any Affiliate and the Participant, if a Participant’s Continuous Service is terminated for Cause, the Option or SAR will terminate upon the date on which the event giving rise to the termination for
Cause first occurred, and the Participant will be prohibited from exercising his or her Option or SAR from and after the date on which the event giving rise to the termination for Cause first occurred (or, if required by law, the date of termination
of Continuous Service). If a Participant’s Continuous Service is suspended pending an investigation of the existence of Cause, all of the Participant’s rights under the Option or SAR will also be suspended during the investigation period.

  
 9 

 (i) Non-Exempt Employees. If an Option or SAR
is granted to an Employee who is a non-exempt employee for purposes of the U.S. Fair Labor Standards Act of 1938, as amended, the Option or SAR will not be first exercisable for any shares of Common Stock
until at least 6 months following the date of grant of the Option or SAR (although the Award may vest prior to such date). Consistent with the provisions of the U.S. Worker Economic Opportunity Act, (i) if such
non-exempt Employee dies or suffers a Disability, (ii) upon a Change in Control in which such Option or SAR is not assumed, continued, or substituted, or (iii) upon the
non-exempt Employee’s retirement (as such term may be defined in the non-exempt Employee’s applicable Award Document, in another agreement between the non-exempt Employee and the Company, or, if no such definition, in accordance with the Company’s then current employment policies and guidelines), the vested portion of any Options and SARs may be exercised
earlier than 6 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. To the extent permitted and/or required for compliance with the U.S. Worker Economic Opportunity Act to ensure that any income derived by a non-exempt
Employee in connection with the exercise, vesting or issuance of any shares under any other Stock Award will be exempt from such employee’s regular rate of pay, the provisions of this paragraph will apply to all Stock Awards and are hereby
incorporated by reference into such Stock Award Documents. 
  

	6.	 PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS AND SARS. 

(a) Restricted Stock Awards. Each Restricted Stock Award Document will be in such form and will contain such terms and conditions as the
Board deems 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 will be held in such form and manner as determined by the Board. The terms and conditions of Restricted Stock Award Documents may change from time to
time, and the terms and conditions of separate Restricted Stock Award Documents need not be identical. Each Restricted Stock Award Document will 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, check, bank draft or money order payable to the Company, (B) past services to the Company or an Affiliate, or (C) any other form of legal consideration (including future services) that may be acceptable to the Board, in its
sole discretion, and permissible under applicable law. 
 (ii) Vesting. Shares of Common Stock awarded under the Restricted Stock
Award Document may be subject to forfeiture to the Company in accordance with a vesting schedule and subject to such conditions as may 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
Document. 

  
 10 

 (iv) Transferability. Common Stock issued pursuant to an Award, and rights to acquire
shares of Common Stock under the Restricted Stock Award Document, will be transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Award Document, as the Board determines in its sole discretion, so
long as such Common Stock remains subject to the terms of the Restricted Stock Award Document. 
 (v) Dividends. 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 Document will be in such form and will contain such terms and
conditions as the Board deems appropriate. The terms and conditions of Restricted Stock Unit Award Documents may change from time to time, and the terms and conditions of separate Restricted Stock Unit Award Documents need not be identical. Each
Restricted Stock Unit Award Document will 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 on or conditions to the vesting of the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate. 

(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 Document. 

(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 Document. 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 dividend equivalents and/or additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents will be subject to all of the same terms and conditions of
the underlying Restricted Stock Unit Award Document to which they relate. 

  
 11 

 (vi) Termination of Participant’s Continuous Service. Except as otherwise
provided in the applicable Restricted Stock Unit Award Document, or other agreement between the Participant and the Company, such portion of the Restricted Stock Unit Award that has not vested will be forfeited upon the Participant’s
termination of Continuous Service. 
 (c) Performance Awards. 

(i) Performance Stock Awards. A Performance Stock Award is a Stock Award that is payable (including that may be granted, vest or
exercised) contingent upon the attainment during a Performance Period of the achievement of certain performance goals. A Performance Stock Award may, but need not, require the completion of a specified period of Continuous Service. The length of any
Performance Period, the performance goals to be achieved during the Performance Period, and the measure of whether and to what degree such performance goals have been attained will be conclusively determined by the Committee, the Board, or an
authorized Officer, in its sole discretion. In addition, to the extent permitted by applicable law and the applicable Award Document, the Board may determine that cash may be used in payment of Performance Stock Awards. 

(ii) Performance Cash Awards. A Performance Cash Award is a cash award that is granted and/or becomes payable contingent upon the
attainment during a Performance Period of the achievement of certain performance goals. A Performance Cash Award may also require the completion of a specified period of Continuous Service. At the time of grant of a Performance Cash Award, the
length of any Performance Period, the performance goals to be achieved during the Performance Period, and the measure of whether and to what degree such performance goals have been attained will be conclusively determined by the Committee, the
Board, or an authorized Officer, in its sole discretion. The Board may specify the form of payment of Performance Cash Awards, which may be cash or other property, or may provide for a Participant to have the option for his or her Performance Cash
Award, or such portion thereof as the Board may specify, to be paid in whole or in part in cash or other property. 
 (iii) Board
Discretion. The Committee, the Board, or an authorized Officer, as the case may be, retains the discretion to reduce or eliminate the compensation or economic benefit due upon attainment of performance goals and to define the manner of
calculating the performance criteria it selects to use for a Performance Period. 
  

	7.	 COVENANTS OF THE COMPANY. 

(a) Availability of Shares. The Company will keep available at all times the number of shares of Common Stock reasonably required to
satisfy then-outstanding Stock Awards. 
 (b) Securities Law Compliance. The Company will seek to obtain from each regulatory
commission or agency having jurisdiction over this 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 will not require
the Company to register under the Securities Act this Plan, any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts and at a reasonable cost, the Company is unable to obtain from any such
regulatory commission or agency the authority 

  
 12 

 
that counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under this Plan, the Company will 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 will not be eligible for the grant of an Award or the subsequent issuance of cash or Common Stock pursuant to the Award if such grant or issuance
would be in violation of any applicable securities law. 
 (c) No Obligation to Notify or Minimize Taxes. The Company will 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 will have no duty or obligation to warn or otherwise advise such holder of a pending termination or
expiration of an Award or a possible period in which the Award may not be exercised. The Company has no duty or obligation to, and does not undertake to, provide tax advice or to minimize the tax consequences of an Award to the holder of such 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 will
constitute general funds of the Company. 
 (b) Corporate Action Constituting Grant of Awards. Corporate action constituting a grant
by the Company of an Award to any Participant will be deemed completed as of the latest date that all necessary corporate action has occurred and all material terms of the Award (including, in the case of stock options, the exercise price thereof)
are fixed, unless otherwise determined by the Board, regardless of when the documentation evidencing the Award is communicated to, or actually received or accepted by, the Participant. In the event that the corporate records (e.g., Board consents,
resolutions or minutes) documenting the corporate action constituting the grant contain terms (e.g., exercise price, vesting schedule or number of shares) that are inconsistent with those in the Award Document as a result of a clerical error in the
papering of the Award Document, the corporate records will control and the Participant will have no legally binding right to the incorrect term in the Award Document. 

(c) Stockholder Rights. No Participant will 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 a Stock Award unless and until (i) such Participant has satisfied all requirements for exercise of, or the issuance of shares of Common Stock under, the Stock Award pursuant to its terms, 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 this Plan, any Award Document or any other instrument executed thereunder or in connection with any Award granted pursuant thereto will confer upon any Participant any right to continue to serve the Company or
an Affiliate in the capacity in effect at the time the Award was granted or any other capacity or will 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, including, but not limited to, 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 organizational
documents of the Company or an Affiliate (including articles of incorporation and bylaws), 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. 

  
 13 

 (e) Change in Time Commitment. In the event a Participant’s regular level of
time commitment in the performance of his or her services for the Company and any Affiliates is reduced (for example, and without limitation, if the Participant is an Employee of the Company and the Employee has a change in status from a full-time
Employee to a part-time Employee or takes an extended leave of absence), or the Participant’s role or primary responsibilities are changed to a level that, in the Board’s determination does not justify the Participant’s unvested
Awards, and such reduction or change occurs after the date of grant of any Award to the Participant, the Board has the right in its sole discretion to (i) make a corresponding reduction in the number of shares or cash amount subject to any
portion of such Award that is scheduled to vest or become payable after the date of such change in time commitment, and (ii) in lieu of or in combination with such a reduction, extend the vesting or payment schedule applicable to such Award. In
the event of any such reduction, the Participant will have no right with respect to any portion of the Award that is so reduced or extended. 

(f) Incentive Stock Option Limitations. 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 USD$100,000 (or such other limit established in the Code)
or otherwise does not comply with the rules governing Incentive Stock Options, the Options or portions thereof that exceed such limit (according to the order in which they were granted) or otherwise do not comply with such rules will be treated as
Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Option Agreement(s). 
 (g) 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 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, will be inoperative if (i) the
issuance of the shares upon the exercise of a Stock Award or acquisition of Common Stock under the Stock Award has been registered under a then currently effective registration statement under the Securities Act, or (ii) 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 this 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. 

  
 14 

 (h) Withholding Obligations. Unless prohibited by the terms of an Award Document, the
Company may, in its sole discretion, satisfy any national, state, local or other tax withholding obligation relating to an 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 Award (only up to the amount permitted that will not cause an adverse accounting consequence
or cost); (iii) withholding cash from an Award settled in cash; (iv) withholding payment from any amounts otherwise payable to the Participant, including proceeds from the sale of shares of Common Stock issued pursuant to a Stock Award; or
(v) by such other method as may be set forth in the Award Document. 
 (i) Electronic Delivery. Any reference herein to a
“written” agreement or document will include any agreement or document delivered electronically, filed publicly at www.sec.gov (or any successor website thereto), or posted on the Company’s intranet (or other shared electronic medium
controlled by the Company to which the Participant has access). 
 (j) 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 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 (to the extent applicable to a Participant). 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 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 this Plan and in accordance with applicable law. 

(k) Compliance with Section 409A. Unless otherwise expressly provided for in an Award Document, or other agreement
between the Participant and the Company, this Plan and Award Documents will be interpreted to the greatest extent possible in a manner that makes this Plan and the Awards granted hereunder exempt from Section 409A of the Code, to the extent
that Section 409A of the Code is applicable to an Award, and, to the extent not so exempt, in compliance with Section 409A of the Code. If the Board determines that any Award granted hereunder is subject to Section 409A of the Code,
the Award Document evidencing such Award will incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the Code, and to the extent an Award Document is silent on terms necessary for compliance,
such terms are hereby incorporated by reference into the Award Document. Notwithstanding anything to the contrary in this Plan (and unless the Award Document specifically provides otherwise), if the shares of Common Stock are publicly traded, and if
a Participant holding an Award that constitutes “deferred compensation” under Section 409A of the Code is a “specified employee” for purposes of Section 409A of the Code and the Participant is otherwise subject to
Section 409A of the Code, no distribution or payment of any amount that is due because of a “separation from service” (as defined in Section 409A of the Code without regard to alternative definitions thereunder) will be issued or
paid before the date that is six (6) months following the date of such Participant’s “separation from service” or, if earlier, the date of the Participant’s death, unless such distribution or payment can be made in a manner
that complies with Section 409A of the Code, and any amounts so deferred will be paid in a lump sum on the day after such six (6) month period elapses, with the balance paid thereafter on the original schedule. 

  
 15 

 (i) Clawback/Recovery. All Awards granted under this Plan will be subject to
recoupment in accordance with any clawback policy that the Company is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise
required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other applicable law. In addition, the Board may impose such other clawback, recovery or recoupment provisions in an Award Document as the Board determines necessary or
appropriate, including, but not limited to, a reacquisition right in respect of previously acquired shares of Common Stock or other cash or property upon the occurrence of Cause. No recovery of compensation under such a clawback policy will be an
event giving rise to a right to resign for “good reason” or “constructive termination” (or similar term) under any agreement with the Company or an Affiliate. 

 

	9.	 ADJUSTMENTS UPON CHANGES IN COMMON STOCK; OTHER CORPORATE EVENTS. 

(a) Capitalization Adjustments. In the event of a Capitalization Adjustment, the Board will appropriately and proportionately adjust:
(i) the class(es) and maximum number of securities subject to this 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 or other property and value (including price per share of stock) subject to outstanding Stock Awards. The Board will make such
adjustments, and its determination will be final, binding and conclusive. 
 (b) Dissolution or Liquidation. Except as otherwise
provided in the Stock Award Document, or other agreement between the Participant and the Company, 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) will 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 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) Change in Control. The following provisions will apply to Awards
in the event of a Change in Control unless otherwise provided in the instrument evidencing the Award or any other written agreement between the Company or any Affiliate and the Participant or unless otherwise expressly provided by the Board at the
time of grant of an Award. In the event of a Change in Control, then, notwithstanding any other provision of this Plan, the Board will take one or more of the following actions with respect to each outstanding Award, contingent upon the closing or
completion of the Change in Control: 
 (i) arrange for the surviving corporation or acquiring corporation (or the surviving or acquiring
corporation’s parent company) to assume or continue the Award or to substitute a similar award for the Award (including, but not limited to, an award to acquire the same consideration per share paid to the stockholders of the Company pursuant
to the Change in Control); 

  
 16 

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

(iii) accelerate the vesting, in whole or in part, of the Award (and, if applicable, the time at which the Award may be exercised) to a date
prior to the effective time of such Change in Control as the Board will determine (or, if the Board will not determine such a date, to the date that is 5 days prior to the effective date of the Change in Control), with such Award terminating if not
exercised (if applicable) at or prior to the effective time of the Change in Control, and with such exercise reversed if the Change in Control does not become effective; 

(iv) arrange for the lapse, in whole or in part, of any reacquisition or repurchase rights held by the Company with respect to the Award; 

(v) cancel or arrange for the cancellation of the Award, to the extent not vested or not exercised prior to the effective time of the Change in
Control, in exchange for such cash consideration, if any, as the Board, in its reasonable determination, may consider appropriate as an approximation of the value of the canceled Award, taking into account the value of the Common Stock subject to
the canceled Award, the possibility that the Award might not otherwise vest in full, and such other factors as the Board deems relevant; and 

(vi) cancel or arrange for the cancellation of the Award, to the extent not vested or not exercised prior to the effective time of the Change
in Control, in exchange for a payment, in such form as may be determined by the Board equal to the excess, if any, of (A) the value in the Change in Control of the property the Participant would have received upon the exercise of the Award
immediately prior to the effective time of the Change in Control, over (B) any exercise price payable by such holder in connection with such exercise. 

The Board need not take the same action or actions with respect to all Awards or portions thereof or with respect to all Participants. The
Board may take different actions with respect to the vested and unvested portions of an Award. 
 In the absence of any affirmative
determination by the Board at the time of a Change in Control, each outstanding Award will be assumed or an equivalent Award will be substituted by such successor corporation or a parent or subsidiary of such successor corporation (the
“Successor Corporation”), unless the Successor Corporation does not agree to assume the Award or to substitute an equivalent Award, in which case the vesting of such Award will accelerate in its entirety (along with, if applicable,
the time at which the Award may be exercised) to a date prior to the effective time of such Change in Control as the Board will determine (or, if the Board will not determine such a date, to the date that is 5 days prior to the effective date of the
Change in Control), with such Award terminating if not exercised (if applicable) at or prior to the effective time of the Change in Control, and with such exercise reversed if the Change in Control does not become effective. 

  
 17 

 (d) Acceleration of Awards upon a Change in Control. An Award may be subject to
additional acceleration of vesting and exercisability upon or after a Change in Control as may be provided in the Award Document for such 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 will occur. 
  

	10.	 TERMINATION OR SUSPENSION OF THIS PLAN. 

The Board or the Compensation Committee may suspend or terminate this Plan at any time. This Plan will have no fixed expiration date; provided,
however, that no Incentive Stock Option may be granted more than 10 years after the later of (i) the Adoption Date and (ii) the adoption by the Board of any amendment to this Plan that constitutes the adoption of a new plan for purposes of
Section 422 of the Code. No Awards may be granted under this Plan while this Plan is suspended or after it is terminated. 
  

	11.	 EFFECTIVE DATE OF PLAN; TIMING OF FIRST GRANT OR EXERCISE. 

This Plan shall come into existence on the Effective Date and no Award may be granted under this Plan prior to the Effective Date. In addition,
no Stock Award may be exercised (or, in the case of a Restricted Stock Award, Restricted Stock Unit Award, or Performance Stock Award, may be granted) and no Performance Cash Award may be settled unless and until this Plan has been approved by the
stockholders of the Company, which approval will be within 12 months before or after the Adoption Date. 
  

	12.	 CHOICE OF LAW. 

The laws of the State of Delaware will govern all questions concerning the construction, validity and interpretation of this Plan, without
regard to that state’s conflict of laws rules. 
  

	13.	 DEFINITIONS. 

As used in this Plan, the following definitions will apply to the capitalized terms indicated below: 

(a) “Adoption Date” means the date this Plan is originally adopted by the Board. 

(b) “Affiliate” means, at the time of determination, any “parent” or “subsidiary” of the Company, as such
terms are defined in Rule 405 of the Securities Act. The Board will have the authority to determine the time or times at which “parent” or “subsidiary” status is determined within the foregoing definition. 

(c) “Award” means a Stock Award or a Performance Cash Award. 

  
 18 

 (d) “Award Document” means a written agreement between the Company and a
Participant, or a written notice issued by the Company to a Participant, evidencing the terms and conditions of an Award. 
 (e)
“Board” means the Board of Directors of the Company. 
 (f) “Capital Stock” means each and every class of
common stock of the Company, regardless of the number of votes per share. 
 (g) “Capitalization Adjustment” means any
change that is made in, or other events that occur with respect to, the Common Stock subject to this Plan or subject to any Stock Award after the Adoption Date without the receipt of consideration by the Company through merger, consolidation,
reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, large nonrecurring cash dividend, stock split, reverse stock split, liquidating dividend, combination of shares, exchange of shares, change in
corporate structure or other similar equity restructuring transaction, as that term is used in Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto). Notwithstanding the foregoing, the conversion
of any convertible securities of the Company will not be treated as a Capitalization Adjustment. 
 (h) “Cause” will have
the meaning ascribed to such term in any written agreement between the Participant and the Company or any Affiliate defining such term and, in the absence of such agreement, such term means, with respect to a Participant, the occurrence of any of
the following events: (i) Participant’s failure substantially to perform his or her duties and responsibilities to the Company or any Affiliate or violation of a policy of the Company or any Affiliate; (ii) Participant’s
commission of any act of fraud, embezzlement, dishonesty or any other misconduct that has caused or is reasonably expected to result in injury to the Company or any Affiliate; (iii) unauthorized use or disclosure by Participant 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 relationship with the Company or any Affiliate; or (iv) Participant’s breach
of any of his or her obligations under any written agreement or covenant with the Company or any Affiliate. The determination as to whether a Participant is being terminated for Cause will be made in good faith by the Company and will be final and
binding on the Participant. Any determination by the Company that the Continuous Service of a Participant was terminated with or without Cause for the purposes of outstanding Awards held by such Participant will have no effect upon any determination
of the rights or obligations of the Company, any Affiliate or such Participant for any other purpose. 
 (i) “Change in
Control” means the occurrence, in a single transaction or in a series of related transactions, of any one or more of the following events: 

(i) any Exchange Act Person becomes the Owner, directly or indirectly, of securities of the Company representing more than 50% of the combined
voting power of the Company’s then outstanding securities other than by virtue of a merger, consolidation or similar transaction. Notwithstanding the foregoing, a Change in Control will not be deemed to occur (A) on account of the
acquisition of securities of the Company directly from the Company, (B) on account of the acquisition of securities of the Company by an investor, any affiliate thereof or any 

  
 19 

 
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 will be deemed to occur; 

(ii) there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) the Company and, immediately after
the consummation of such merger, consolidation or similar transaction, the stockholders of the Company immediately prior thereto do not Own, directly or indirectly, either (A) outstanding voting securities representing 50% or more of the
combined outstanding voting power of the surviving Entity in such merger, consolidation or similar transaction or (B) 50% or more of the combined outstanding voting power of the parent of the surviving Entity in such merger, consolidation or similar
transaction, in each case in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such transaction; 

(iii) there is consummated a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company
and its Subsidiaries, other than a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries to an Entity, more than 50% of the combined voting power of the voting securities
of which are Owned by stockholders 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 

(iv) individuals who, on the Adoption Date, are members of the Board (the “Incumbent Board”) cease for any reason to
constitute at least a majority of the members of the Board; provided, however, that if the appointment or election (or nomination for election) of any new Board member was approved or recommended by a majority vote of the members of the Incumbent
Board then still in office, such new member will, for purposes of this Plan, be considered as a member of the Incumbent Board. 

Notwithstanding the foregoing definition or any other provision of this Plan, (A) the term Change in Control will 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 will supersede the foregoing definition with respect to Awards subject to such agreement; provided, however, that if no definition of Change in Control or any analogous term is set forth in such an individual written
agreement, the foregoing definition will apply. 

  
 20 

 If required for compliance with Section 409A of the Code, in no event will a Change in
Control be deemed to have occurred if such transaction is not also a “change in the ownership or effective control of” the Company or “a change in the ownership of a substantial portion of the assets of” the Company as determined
under U.S. Treasury Regulation Section 1.409A-3(i)(5) (without regard to any alternative definition thereunder). The Board may, in its sole discretion and without a Participant’s consent, amend the
definition of “Change in Control” to conform to the definition of “Change in Control” under Section 409A of the Code, and the regulations thereunder. 

(j) “Code” means the U.S. Internal Revenue Code of 1986, as amended, including any applicable regulations and guidance
thereunder. 
 (k) “Committee” means a committee of one (1) or more Directors to whom authority has been delegated by
the Board in accordance with Section 2(c). 
 (l) “Compensation Committee” means the Compensation
Committee of the Board. 
 (m) “Common Stock” means the common stock of the Company. 

(n) “Company” 89bio, Inc., a Delaware corporation. 

(o) “Consultant” means any person, including an advisor, who is (i) engaged by the Company or an Affiliate to render
consulting or advisory services and is compensated for such services, or (ii) serving as a member of the board of directors of an Affiliate and is compensated for such services. However, service solely as a Director, or payment of a fee for
such service, will not cause a Director to be considered a “Consultant” for purposes of this Plan. Notwithstanding the foregoing, a person is treated as a Consultant under this Plan only if a Form Registration Statement on Form S-8 or a successor form under the Securities Act is available to register either the offer or the sale of the Company’s securities to such person. 

(p) “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, Consultant or Director 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, will not terminate a Participant’s Continuous Service. For example, a change in status from an
Employee of the Company to a Consultant of an Affiliate or to a Director will not constitute an interruption of Continuous Service. If the Entity for which a Participant is rendering services ceases to qualify as an Affiliate, as determined by the
Board in its sole discretion, such Participant’s Continuous Service will be considered to have terminated on the date such Entity ceases to qualify as an Affiliate. 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 will 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. In addition, if required for exemption from or compliance with Section 409A of the Code, the determination of whether there has
been a termination of Continuous Service will be made, and such term will be construed, in a manner that is consistent with the definition of “separation from service” as defined under U.S. Treasury Regulation Section 1.409A-1(h) (without regard to any alternative definition thereunder). A leave of absence will be treated as Continuous Service for purposes of vesting in a Stock Award only to such extent as may be
provided in the applicable Award Document, 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. 

  
 21 

 (q) “Director” means a member of the Board. 

(r) “Disability” means, with respect to a Participant, the inability of such Participant to engage in any substantial gainful
activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or that has lasted or can be expected to last for a continuous period of not less than 12 months as provided in Sections 22(e)(3)
and 409A(a)(2)(C)(i) of the Code, and will be determined by the Board on the basis of such medical evidence as the Board deems warranted under the circumstances. 

(s) “Effective Date” means September 17, 2019. 

(t) “Employee” means any person providing services as an employee of the Company or an Affiliate. However, service solely as a
Director, or payment of a fee for such services, will not cause a Director to be considered an “Employee” for purposes of this Plan. 

(u) “Entity” means a corporation, partnership, limited liability company or other entity. 

(v) “Exchange Act” means the U.S. Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated
thereunder. 
 (w) “Exchange Act Person” means any natural person, Entity or “group” (within the meaning of
Section 13(d) or 14(d) of the Exchange Act), except that “Exchange Act Person” will not include (i) the Company or any Subsidiary of the Company, (ii) any employee benefit plan of the Company or any Subsidiary of the Company

2019 EQUITY INCENTIVE PLAN 

STOCK OPTION AGREEMENT 

(UNITED STATES AWARD AGREEMENT) 
 This
Stock Option Agreement is made and entered into by and between 89bio, Inc., a Delaware corporation (“Company”), and the Optionee identified in the Notice of Grant of Stock Option (“Grant Notice”) which is attached hereto
(“Optionee”). 
 1. Grant of Stock Option. Subject to the terms and conditions set forth herein, the
Company hereby grants to Optionee a stock option (the “Stock Option”) to purchase from the Company, at the Exercise Price set forth in the Grant Notice, the number of Option Shares set forth in the Grant Notice. This Option is intended to
be an Incentive Stock Option or a Nonstatutory Stock Option as set forth on the Grant Notice. Capitalized terms not otherwise defined herein shall have the meanings set forth in the Plan or the Grant Notice. 

2. Incentive Stock Option. If, and only to the extent, that this Stock Option is identified as an Incentive Stock
Option on the Grant Notice, it is intended to qualify as an “incentive stock option” under Section 422 of the United States Internal Revenue Code of 1986, as amended (the “Code”) provided, however (a) this Stock Option
shall cease to qualify as an Incentive Stock Option under the Code to the extent it is exercised (i) more than three months after the date the Optionee ceases to be an Employee for any reason other than death or permanent and total disability
(as defined in Section 22(e)(3) of the Code), (ii) more than 12 months after the date the Optionee ceases to be an Employee by reason of such permanent and total disability or (iii) after the Optionee has been on a leave of absence for
more than three months, unless the Optionee’s reemployment rights are guaranteed by statute or by contract; and (b) to the extent that the Stock Option (together with all other Company Incentive Stock Options held by Optionee) becomes
exercisable for the first time during any calendar year for shares having a Fair Market Value greater than $100,000, the portion of such options which exceeds such amount will be treated as Nonstatutory Stock Options. If the Code is amended to
provide for a different limitation from that set forth in this Section, such different limitation shall be deemed incorporated herein effective as of the date required or permitted by such amendment to the Code. 

3. Expiration of Stock Option. The Stock Option shall expire and cease to be exercisable as of the earlier of
(i) the Expiration Date set forth in the Grant Notice or (ii) the date specified below in connection with the Optionee’s termination of Continuous Service: 

(a) If the Optionee’s Continuous Service terminates by reason of death or Disability, the Optionee (or the Optionee’s estate,
beneficiary or legal representative, as applicable) may exercise any portion of the Stock Option that is vested and exercisable at the time of such termination until the date that is twelve (12) months following the date of such termination.
Any portion of the Stock Option that is not vested and exercisable at the time of such termination shall be forfeited and canceled as of the date of such termination. 

(b) If the Optionee’s Continuous Service terminates for any reason other than death, Disability, or Cause, the Optionee may exercise any
portion of the Stock Option that is vested and exercisable at the time of such termination until the date that is three (3) months following the date of such termination. Any portion of the Stock Option that is not vested and exercisable at the
time of such termination shall be forfeited and canceled as of the date of such termination. 

  
 -1- 

 (d) If the Optionee’s Continuous Service is terminated by the Company for Cause, the
entire Stock Option, whether or not then vested and exercisable, shall be immediately forfeited and canceled as of the date of such termination. 

4. Exercise. 

4.1 Exercisability. Subject to the terms and conditions of this Stock Option Agreement, the Stock Option shall
become exercisable at such time or times, during such period and for such number of Option Shares as is set forth in the Grant Notice. Upon the expiration of the applicable exercise period or (if earlier) upon the expiration of the Stock Option
term, the Stock Option shall terminate and cease to be outstanding for any Option Shares for which the Stock Option has not been exercised. 

4.2 Exercise Agreement. Optionee may exercise the Stock Option by delivering to the Company, either in person or by
certified or registered mail or such other manner as approved by the Company, a duly executed exercise agreement in a form approved by the Company from time to time for such exercises (the “Exercise Agreement”), and payment in full of the
purchase price as provided in Section 4.3 of this Stock Option Agreement. A copy of the Exercise Agreement will be provided by the Company to Optionee upon request, and no exercise of this Stock Option may be effected without the
Optionee’s execution of such Exercise Agreement in the form approved by the Company and containing the provisions noted above. 
 4.3
Payment of Purchase Price. The purchase price for any Option Shares for which this Stock Option is exercised shall be paid in full in United States dollars at the time Optionee delivers to the Company the Exercise Agreement. The
purchase price shall be paid in one or a combination of the following, to the extent permitted by the Company: (a) cash, check, bank draft or money order payable to the Company; (b) Common Stock; (c) through the delivery of a notice
that Optionee has placed a market sell order with a broker acceptable to the Company with respect to shares of Common Stock then issuable upon exercise of the Stock Option, and that the broker has been directed to pay a sufficient portion of the net
proceeds of the sale to the Company in satisfaction of the purchase price; provided that payment of such proceeds is then made to the Company at such time as may be required by the Company, but in any event not later than the
settlement of such sale; or (d) net exercise (solely in the case of a Nonstatutory Stock Option). In addition to the purchase price, the Optionee shall pay the amount of tax required to be withheld (if any) by the Company or any Affiliate or
Subsidiary as a result of the exercise of the Stock Option. The Optionee acknowledges that the Company shall have the right to deduct any taxes required to be withheld by law in connection with the exercise of the Stock Option from any amounts
payable by it to the Optionee (including, without limitation, future cash wages). 
 4.4 Issuance of Shares. Fractional
shares may not be exercised. Shares of Common Stock will be issued as soon as practical after exercise. Notwithstanding the above, the Company shall not be obligated to deliver any shares of Common Stock during any period when the Company determines
that the exercisability of the Stock Option or the delivery of shares of Common Stock hereunder would violate any federal, state or other applicable laws. Until the consummation of an initial public offering of the Company’s Common Stock
(“IPO”), any shares of Common Stock acquired upon the exercise of the Stock Options shall be voted by an irrevocable proxy, in the form attached hereto as Exhibit A. Such proxy shall be signed by the Optionee as a pre-condition to the exercise of any portion of the Stock Options by the Optionee. 

  
 -2- 

 5. Change in Control. Unless otherwise provided in a Separate Agreement, upon
the occurrence of a Change in Control, Sections 9(c) and 9(d) of the Plan shall control. 
 6. Restrictions on Resales.
The Company may impose such restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any resales by the Optionee or other subsequent transfers by the Optionee of any shares of Common Stock issued as a
result of the exercise of the Stock Option, including without limitation (a) restrictions under an insider trading policy, (b) restrictions designed to delay and/or coordinate the timing and manner of sales by Optionee and other
optionholders and (c) restrictions as to the use of a specified brokerage firm for such resales or other transfers. 
 7.
Rights as a Stockholder. Optionee shall have no rights as a stockholder of the Company with respect to any Option Shares until the issuance of the Common Stock subject to the Stock Option has been entered into the books and
records of the Company. 
 8. No Transfer of Stock Option. Except as permitted by the Board or as permitted under
the Plan, the Optionee may not assign or transfer the Stock Option to anyone other than by will or the laws of descent and distribution and the Stock Option shall be exercisable only by the Optionee during his or her lifetime. 

9. Other Agreements Superseded. The Grant Notice, this Stock Option Agreement, the Plan and any Separate Agreement,
if applicable, constitute the entire understanding between the Optionee and the Company regarding the Stock Option. Any prior agreements, commitments or negotiations concerning the Stock Option are superseded. 

10. Limitation in Interest in Shares Subject to Stock Option. Neither the Optionee (individually or as a member of a
group) nor any beneficiary or other person claiming under or through the Optionee shall have any right, title, interest, or privilege in or to any shares of Common Stock allocated or reserved for the purpose of the Plan or subject to the Grant
Notice or this Stock Option Agreement except as to such shares of Common Stock, if any, as shall have been issued to such person upon exercise of the Stock Option or any part of it. Nothing in the Plan, in the Grant Notice, this Stock Option
Agreement or any other instrument executed pursuant to the Plan shall confer upon the Optionee any right to continue in the Company’s employ or service nor limit in any way the Company’s right to terminate the Optionee’s employment or
other service at any time for any reason. 
 11. No Liability of Company. The Company and any Affiliate or Subsidiary
which is in existence or hereafter comes into existence shall not be liable to the Optionee or any other person as to: (a) the non-issuance or sale of shares of Common Stock as to which the Company has
been unable to obtain from any regulatory body having jurisdiction the authority deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any shares hereunder; and (b) any tax consequence expected, but not
realized, by the Optionee or other person due to the receipt, exercise or settlement of any Stock Option granted hereunder. 
 12.
Market Stand-Off. In connection with any public offering of the Company’s equity securities, pursuant to an effective registration statement, for such period as the Company or its
underwriters may request, the Optionee shall not, directly or indirectly, sell, make any short sale of, loan, hypothecate, pledge, offer, grant or sell any option or other contract for the purchase of, purchase any option or other contract for the
sale of, or otherwise dispose of or transfer, or agree to engage in any of the foregoing transactions with respect to, any shares of Common Stock acquired under the Plan without the prior written consent of the Company or its underwriters. 

  
 -3- 

 13. General Provisions.  

13.1 Tax Withholding. Whenever Option Shares are to be issued hereunder, the Company may require the Optionee to remit to the
Company an amount sufficient to satisfy any national, state and local or other withholding tax requirements prior to the delivery of Option Shares. 

13.2 Governing Plan Document. The Stock Option is subject to all the provisions of the Plan, the provisions of which are
hereby made a part of the Stock 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.

or more provisions of this Stock Option Agreement are held to be unenforceable under applicable law, such provision shall be excluded from this Stock Option Agreement, and the balance of the Stock Option Agreement shall be interpreted as if such
provision were so excluded and shall be enforceable in accordance with its terms. The parties agree to replace such illegal, void, invalid or unenforceable provision of this Stock Option Agreement with a legal, valid and enforceable provision that

(d) If the Optionee’s Continuous Service is terminated by the Company for Cause, the entire Stock Option, whether or not then vested and
exercisable, shall be immediately forfeited and canceled as of the date of such termination. 
 4. Exercise. 

4.1 Exercisability. Subject to the terms and conditions of this Stock Option Agreement, the Stock Option shall
become exercisable at such time or times, during such period and for such number of Option Shares as is set forth in the Grant Notice. Upon the expiration of the applicable exercise period or (if earlier) upon the expiration of the Stock Option
term, the Stock Option shall terminate and cease to be outstanding for any Option Shares for which the Stock Option has not been exercised. 

4.2 Exercise Agreement. Optionee may exercise the Stock Option by delivering to the Company, either in person or by
certified or registered mail or such other manner as approved by the Company, a duly executed exercise agreement in a form approved by the Company from time to time for such exercises (the “Exercise Agreement”), and payment in full of the
purchase price as provided in Section 4.3 of this Stock Option Agreement. A copy of the Exercise Agreement will be provided by the Company to Optionee upon request, and no exercise of this Stock Option may be effected without the
Optionee’s execution of such Exercise Agreement in the form approved by the Company and containing the provisions noted above. 
 4.3
Payment of Purchase Price. The purchase price for any Option Shares for which this Stock Option is exercised shall be paid in full in United States dollars at the time Optionee delivers to the Company the Exercise Agreement. The
purchase price shall be paid in one or a combination of the following, to the extent permitted by the Company: (a) cash, check, bank draft or money order payable to the Company; (b) Common Stock; (c) through the delivery of a notice
that Optionee has placed a market sell order with a broker acceptable to the Company with respect to shares of Common Stock then issuable upon exercise of the Stock Option, and that the broker has been directed to pay a sufficient portion of the net
proceeds of the sale to the Company in satisfaction of the purchase price; provided that payment of such proceeds is then made to the Company at such time as may be required by the Company, but in any event not later than the
settlement of such sale; or (d) net exercise. In addition to the purchase price, the Optionee shall pay the amount of tax required to be withheld (if any) by the Company or any Affiliate or Subsidiary as a result of the exercise of the Stock
Option. 
 4.4 Issuance of Shares. Fractional shares may not be exercised. Shares of Common Stock will be issued as soon
as practical after exercise. Notwithstanding the above, the Company shall not be obligated to deliver any shares of Common Stock during any period when the Company determines that the exercisability of the Stock Option or the delivery of shares of
Common Stock hereunder would violate any federal, state or other applicable laws. Until the 

  
 -4- 

 
consummation of an initial public offering of the Company’s Common Stock (“IPO”), any shares of Common Stock acquired upon the exercise of the Stock Options shall be voted by an
irrevocable proxy, in the form attached hereto as Exhibit A. Such proxy shall be signed by the Optionee as a pre-condition to the exercise of any portion of the Stock Options by the Optionee. 

5. Change in Control. Unless otherwise provided in a Separate Agreement, upon the occurrence of a Change in Control, Sections
9(c) and 9(d) of the Master Plan shall control. 
 6. Restrictions on Resales.  

(a) Any transfer or other disposition of the shares of Common Stock to be issued upon exercise of the Stock Option (and/or any securities of
the Company received subsequently following any realization of rights, including without limitation, bonus stock), shall be subject to the limitations set forth in the Plan and this Stock Option Agreement; (ii) the Company’s articles of
incorporation and bylaws (as amended from time to time); (iii) any stockholders’ agreement to which the holders of Common Stock of the Company may be bound; (iv) restrictions included in the Company’s insider trading policy, or
similar document, if any; (v) any applicable law (including securities law of any applicable jurisdiction); and (vi) the signing of an irrevocable proxy by the transferee in the form attached hereto as Exhibit A, mutatis mutandis.

 (b) Notwithstanding the foregoing, as long as the Option and any rights and interests with respect thereto are held by the Trustee on
behalf of the Participant, all rights of the Participant over the Stock Option, the Common Stock covered thereby and any rights thereto are personal, cannot be transferred, assigned, pledged or mortgaged, other than by will or laws of descent and
distribution. 
 7. Rights as a Stockholder. Optionee shall have no rights as a stockholder of the Company with
respect to any Option Shares until the issuance of the Common Stock subject to the Stock Option has been entered into the books and records of the Company. 

8. No Transfer of Stock Option. Except as permitted by the Board or as permitted under the Plan, the Optionee may
not assign or transfer the Stock Option to anyone other than by will or the laws of descent and distribution and the Stock Option shall be exercisable only by the Optionee during his or her lifetime. 

9. Other Agreements Superseded. The Grant Notice, this Stock Option Agreement, the Plan, the Trust Deed and any
Separate Agreement, if applicable, constitute the entire understanding between the Optionee and the Company regarding the Stock Option. Any prior agreements, commitments or negotiations concerning the Stock Option are superseded. 

10. Limitation in Interest in Shares Subject to Stock Option. Neither the Optionee (individually or as a member of a
group) nor any beneficiary or other person claiming under or through the Optionee shall have any right, title, interest, or privilege in or to any shares of Common Stock allocated or reserved for the purpose of the Plan or subject to the Grant
Notice or this Stock Option Agreement except as to such shares of Common Stock, if any, as shall have been issued to such person upon exercise of the Stock Option or any part of it. Nothing in the Plan, in the Grant Notice, this Stock Option
Agreement or any other instrument executed pursuant to the Plan shall confer upon the Optionee any right to continue in the Company’s employ or service nor limit in any way the Company’s right to terminate the Optionee’s employment or
other service at any time for any reason. 

  
 -5- 

 11. No Liability of Company. The Company and any Affiliate or
Subsidiary which is in existence or hereafter comes into existence shall not be liable to the Optionee or any other person as to: (a) the non-issuance or sale of shares of Common Stock as to which the
Company has been unable to obtain from any regulatory body having jurisdiction the authority deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any shares hereunder; and (b) any tax consequence expected, but
not realized, by the Optionee or other person due to the receipt, exercise or settlement of any Stock Option granted hereunder. 
 12.
Market Stand-Off. In connection with any public offering of the Company’s equity securities, pursuant to an effective registration statement, for such period as the Company or its
underwriters may request, the Optionee shall not, directly or indirectly, sell, make any short sale of, loan, hypothecate, pledge, offer, grant or sell any option or other contract for the purchase of, purchase any option or other contract for the
sale of, or otherwise dispose of or transfer, or agree to engage in any of the foregoing transactions with respect to, any shares of Common Stock acquired under the Plan without the prior written consent of the Company or its underwriters. 

13. General Provisions.  

13.1 Tax Matters. 

(a) The Company does not represent or warrant that the Stock Option (or the purchase or sale of the shares of Common Stock subject hereto) will
be subject to particular tax treatment. The receipt of the Stock Option, the exercise thereof or the disposal of the Stock Option or the shares of Common Stock covered thereby may result in tax and/or other mandatory payment consequences. The
Participant acknowledges that he/she should review with his/her own tax advisors the tax treatment of the Stock Option (including the purchase and sale of shares of Common Stock subject hereto) and should rely solely on those advisors in that
regard. 
 (b) Any tax arising with respect to the grant or exercise of the Stock Option, the payment for, or disposition of, shares of
Common Stock covered thereby, or from any other event or act in connection therewith (of the Company, its Affiliates, the Trustee or the Participant, including without limitation, in the event that the Stock Option does not qualify under the tax
classification/tax track in which it was intended), shall be borne solely by the Participant. The Company, its Affiliates, and the Trustee shall be entitled to withhold taxes according to the requirements of any applicable laws, rules, and
regulations, including withholding taxes at source. The Participant shall indemnify the Company, its Affiliates, and the Trustee, as the case may be, and hold each of them harmless against and from any and all liability for any such tax or interest
or penalty thereon, including without limitation, liabilities relating to the necessity to withhold, or to have withheld, any such tax from any payment made to the Participant. The Company or any Affiliate thereof may exercise such indemnification
by deducting the taxes subject to indemnification from Participant’s salaries or remunerations. 
 (c) Notwithstanding anything to the
contrary, the Board, or when applicable, the Trustee shall not release the Stock Option or any Common Stock allocated or issued upon exercise of the Stock Option (including rights or bonus stock) prior to the full payment of the Participant’s
tax liabilities arising from the Stock Option which was granted to him/her and/or any Common Stock allocated or issued upon exercise of such Stock Option, or the sale or other disposition of such Common Stock. 

  
 -6- 

 (d) The Participant hereby acknowledges that he or she is familiar with the provisions of
Section 102 and the regulations and rules promulgated thereunder, including without limitations the type of Award granted hereunder and the tax implications applicable to such grant. 

(e) In the event that the requirements for the Approved 102 Award are not met, then this Stock Option shall be regarded as Unapproved 102
Award. 
 13.2 Governing Plan Document. The Stock Option is subject to all the provisions of the Plan, the provisions of
which are hereby made a part of the Stock 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. 

13.3 Governing Law. This Stock Option Agreement shall be governed by, and construed in accordance with, the laws of the
State of Delaware, without regard to principles of conflicts of law, provided, however, that all questions concerning the construction, validity and interpretation of this Stock Option Agreement in connection with tax matters shall be governed by,
and construed in accordance with, the laws of the State of Israel, without regard to principles of conflicts of law. 
 13.4 Electronic
Delivery. By executing the Grant Notice, the Optionee hereby consents to the delivery of information (including, without limitation, information required to be delivered to the Optionee pursuant to applicable securities laws)
regarding the Company and its Affiliates or Subsidiaries, the Plan, the Stock Option and the Common Stock via Company web site or other electronic delivery. 

13.5 Privacy Protection. The Participant hereby authorizes the Company and any Affiliate thereof to provide the Trustee with any
information required for the purpose of administering the Plan, including executing its obligations according to Section 102 and the trust agreement, including without limitation information about the Participant’s Stock Option, shares of
Common Stock, income tax rates, salary bank account, contact details and identification number 
 13.6 Notices. Any
notice required or permitted to be delivered under this Stock Option Agreement shall be in writing (which shall include electronic transmission) and shall be deemed received (i) the business day following electronic verification of receipt if
sent electronically, (ii) upon personal delivery to the party to whom the notice is directed, or (iii) the business day following deposit with a reputable overnight courier (or the second business day following deposit in the case of an
international delivery). Notice shall be addressed to the Company at its principal executive office and to the Optionee at the address that he or she most recently provided to the Company. The recipient may acknowledge actual receipt at a time
earlier than the deemed receipt set forth herein or by a means other than that set forth herein. 
 13.7
Successors/Assigns. This Stock Option Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective permitted heirs, beneficiaries, successors and assigns. 

13.8 Severability. If one or more provisions of this Stock Option Agreement are held to be unenforceable under
applicable law, such provision shall be excluded from this Stock Option Agreement, and the balance of the Stock Option Agreement shall be interpreted as if such provision were so excluded and shall be enforceable in accordance with its terms. The
parties agree to replace such illegal, void, invalid or unenforceable provision of this Stock Option Agreement with a legal, valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such
illegal, void, invalid or unenforceable provision.

days) prior to an Enrollment Period and/or that customary employment exceed a specified number of hours or period during a calendar year (not to exceed 20 hours per week or 5 months in a calendar year) to be eligible to participate with respect to

 Section 5. PARTICIPATION 

(a) An Employee who is eligible to participate in the Plan in accordance with its terms at the beginning of an Enrollment Period for an
Offering Period and elects to participate in such Offering Period shall automatically receive an option in accordance with Section 8(a). Such an Employee shall become a Participant by completing and submitting, on or before the date prescribed
by the Committee with respect to a given Offering Period, a completed payroll deduction authorization and Plan enrollment form provided by Sponsor or its Participating Subsidiaries or by following an electronic or other enrollment process as
prescribed by the Committee. An eligible Employee may authorize payroll deductions at the rate of any whole percentage of the Employee’s Compensation, not to be less than one percent (1.0%) and not to exceed fifteen percent (15.0%) of the
Employee’s Compensation (or such other percentages as the Committee may establish from time to time before an Enrollment Period for a future Offering Period) of such Employee’s Compensation on each payday during the Offering Period. All
payroll deductions will be held in a general corporate account or a trust account. No interest shall be paid or credited to the Participant with respect to such payroll deductions. Sponsor shall maintain or cause to be maintained a separate
bookkeeping account for each Participant under the Plan and the amount of each Participant’s payroll deductions shall be credited to such account. A Participant may not make any additional payments into such account, unless payroll deductions
are prohibited under Applicable Law, in which case the provisions of Section 5(b) of the Plan shall apply. 
 (b) Notwithstanding any
other provisions of the Plan to the contrary, in locations where local law prohibits payroll deductions, an eligible Employee may elect to participate through contributions to his or her account under the Plan in a form acceptable to the Committee.
In such event, any such Employees shall be deemed to be participating in a sub-plan, unless the Committee otherwise expressly provides that such Employees shall be treated as participating in the Plan. 

(c) Under procedures and at times established by the Committee, a Participant may withdraw from the Plan during an Offering Period, by
completing and filing a new payroll deduction authorization and Plan enrollment form with the Company or by following electronic or other procedures prescribed by the Committee. If a Participant withdraws from the Plan during an Offering Period, his
or her accumulated payroll deductions will be refunded to the Participant without interest, his or her right to participate in the current Offering Period will be automatically terminated and no further payroll deductions for the purchase of Common
Stock will be made during the Offering Period. Any Participant who wishes to withdraw from the Plan during an Offering Period, must complete the withdrawal procedures prescribed by the Committee, subject to any rules established by the Committee, or
changes to such rules, pertaining to the timing of withdrawals, limiting the frequency with which Participants may withdraw and re-enroll in the Plan, or imposing a waiting period on Participants wishing to re-enroll following withdrawal. 
 (d) A Participant may not increase his or her rate of contribution
through payroll deductions or otherwise during a given Offering Period. A Participant may decrease his or her rate of contribution through payroll deductions during a given Offering Period during such times specified by the Committee by filing a new
payroll deduction authorization and Plan enrollment 

  
 5 

 
form or by following electronic or other procedures prescribed by the Committee. If a Participant has not followed such procedures to change the rate of contribution, the rate of contribution
shall continue at the originally elected rate throughout the Offering Period and future Offering Periods. Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code for a given calendar year, the
Committee may reduce a Participant’s payroll deductions to zero percent (0%) at any time during an Offering Period scheduled to end during such calendar year. Payroll deductions shall re-commence at the
rate provided in such Participant’s enrollment form at the beginning of the first Offering Period which is scheduled to end in the following calendar year, unless terminated by the Participant as provided in Section 5(c). 

Section 6. TERMINATION OF EMPLOYMENT 

In the event any Participant terminates employment with Sponsor and its Participating Subsidiaries for any reason (including death) prior to
the expiration of an Offering Period, the Participant’s participation in the Plan shall terminate and all amounts credited to the Participant’s account shall be paid to the Participant or, in the case of death, to the Participant’s
heirs or estate, without interest. Whether a termination of employment has occurred shall be determined by the Committee. If a Participant’s termination of employment occurs within a certain period of time as specified by the Committee (not to
exceed 30 days) prior to the Purchase Date of the Offering Period then in progress, his or her option for the purchase of shares of Common Stock will be exercised on such Purchase Date in accordance with Section 9 as if such Participant were
still employed by the Company. If the Committee does not establish different rules with respect to an Offering Period, then if a Participant’s termination of employment occurs on or after the fifth (5th) working day preceding the Purchase Date of an Offering Period, then his or her option for the purchase of shares of Common Stock will be exercised on such Purchase Date in accordance with
Section 9 as if such Participant were still employed by the Company. Following the purchase of shares on such Purchase Date, the Participant’s participation in the Plan shall terminate and all amounts credited to the Participant’s
account shall be paid to the Participant or, in the case of death, to the Participant’s heirs or estate, without interest. The Committee may also establish rules regarding when leaves of absence or changes of employment status will be
considered to be a termination of employment, including rules regarding transfer of employment among Participating Subsidiaries, Subsidiaries and Sponsor, and the Committee may establish termination-of-employment procedures for this Plan that are independent of similar rules established under other benefit plans of Sponsor and its Subsidiaries; provided that such procedures are not in
conflict with the requirements of Section 423 of the Code. 
 Section 7. STOCK 

Subject to adjustment as set forth in Section 11 and the “evergreen” provision in this Section 7, the aggregate number of
shares of Common Stock which may be issued pursuant to the Plan shall not exceed 225,188 shares (the “Share Reserve”). The Share Reserve will automatically increase on January 1st
of each calendar year, for ten years, commencing on January 1 of the calendar year following the Effective Date, in an amount equal to one percent (1%) of the total number of shares of Common Stock outstanding on December 31st of the preceding calendar year. The Board may act prior to January 1st of a given year to provide that there will be no January 1st increase of the Share Reserve for such year or that the increase in the Share Reserve for such year will be a smaller number of shares of Common Stock than would otherwise occur pursuant to the
preceding sentence. 

  
 6 

 Notwithstanding the above, subject to adjustment as set forth in Section 11, the
maximum number of shares of Common Stock that may be issued to any Employee in a given Offering Period shall be 1,666. The Committee may change this limitation at any time on a prospective basis to apply to future Offering Periods. If, on a given
Purchase Date, the number of shares with respect to which options are to be exercised exceeds either maximum, the Committee shall make, as applicable, such adjustment or pro rata allocation of the shares remaining available for purchase in as
uniform a manner as shall be practicable and as it shall determine to be equitable. 
 Section 8. OFFERING 

(a) On the Commencement Date relating to each Offering Period, each eligible Employee, whether or not such Employee has elected to participate
as provided in Section 5(a), shall be granted an option to purchase that number of whole shares of Common Stock (as adjusted as set forth in Section 11) not to exceed that number of shares of Common Stock determined in accordance with the
last paragraph of Section 7 above (or such lower number of shares as determined by the Committee), which may be purchased with the payroll deductions accumulated on behalf of such Employee during each Offering Period at the purchase price
specified in Section 8(b) below, subject to the additional limitation that no Employee participating in the Plan shall be granted an option to purchase Common Stock under the Plan if such option would permit his or her rights to purchase stock
under all employee stock purchase plans (described in Section 423 of the Code) of Sponsor and its Subsidiaries to accrue at a rate which exceeds Twenty-Five Thousand Dollars (USD$25,000) of the Market Value of such Common Stock (determined at
the time such option is granted) for each calendar year in which such option is outstanding at any time. For purposes of the Plan, an option is “granted” on a Participant’s Commencement Date. An option will expire upon the earliest to
occur of (i) the termination of a Participant’s participation in the Plan or such Offering Period, (ii) the beginning of a subsequent Offering Period in which such Participant is participating, or (iii) the termination of the
Offering Period. This Section 8(a) shall be interpreted so as to comply with Code Section 423(b)(8). 
 (b) The Purchase Price
under each option shall be with respect to an Offering Period the lower of (i) a percentage (not less than eighty-five percent (85%)) (“Designated Percentage”) of the Offering Price, or (ii) the Designated Percentage of
the Market Value of a share of Common Stock on the Purchase Date on which the Common Stock is purchased; provided that the Purchase Price may be adjusted by the Committee pursuant to Sections 11 or 12 in accordance with Section 424(a) of the
Code. For a given Offering Period, the Designated Percentage shall be established no later than the beginning of the Enrollment Period for such Offering Period. The Committee may change the Designated Percentage with respect to any future Offering
Period, but not to below eighty-five percent (85%), and the Committee may determine with respect to any prospective Offering Period that the Purchase Price shall be the Designated Percentage of the Market Value of a share of the Common Stock solely
on the Purchase Date. If the Committee does not established the Designated Percentage prior to the beginning of the Enrollment Period for a given Offering Period, the Designated Percentage for such Offering Period shall be eighty-five percent (85%).

  
 7 

 Section 9. PURCHASE OF STOCK 

Unless a Participant withdraws from the Plan as provided in Section 5(c), terminates employment prior to the end of an Offering Period as
provided in Section 6, or except as provided in Sections 7, 12 or 14(b), upon the expiration of each Offering Period, a Participant’s option shall be exercised automatically for the purchase of that number of whole shares of Common Stock
which the accumulated payroll deductions credited to the Participant’s account at that time shall purchase at the applicable price specified in Section 8(b) in accordance with the terms of the Plan, including Section 7. If a
Participant’s contributions are collected in a currency other than U.S. Dollars, then unless otherwise provided by the Committee with respect to an Offering Period, such contributions shall be converted into U.S. Dollars using an exchange rate
prevailing on the Purchase Date as selected in the reasonable determination of the Sponsor. Notwithstanding the foregoing, Sponsor or its Participating Subsidiary may make such provisions and take such action as it deems necessary or appropriate for
the withholding of taxes and/or social insurance and/or other amounts which Sponsor or its Participating Subsidiary determines is required by Applicable Law. Each Participant, however, shall be responsible for payment of all individual tax
liabilities arising under the Plan. The shares of Common Stock purchased upon exercise of an option hereunder shall be considered for tax purposes to be sold to the Participant on the Purchase Date. A Participant’s option to purchase shares of
Common Stock hereunder is exercisable only by him or her. 
 Section 10. PAYMENT AND DELIVERY 

As soon as practicable after the exercise of an option, Sponsor shall deliver or cause to have delivered to the Participant a record of the
Common Stock purchased and the balance of any amount of payroll deductions credited to the Participant’s account not used for the purchase of Common Stock, except as specified below. The Committee may permit or require that shares be deposited
directly with a broker designated by the Committee or to a designated agent of the Company, and the Committee may utilize electronic or automated methods of share transfer. The Committee may require that shares be retained with such broker or agent
for a designated period of time and/or may establish other procedures to permit tracking of disqualifying dispositions of such shares. Sponsor or its Participating Subsidiary shall retain the amount of payroll deductions used to purchase Common
Stock as full payment for the Common Stock and the Common Stock shall then be fully paid and non-assessable. No Participant shall have any voting, dividend, or other Stockholder rights with respect to shares
subject to any option granted under the Plan until the shares subject to the option have been purchased and delivered to the Participant as provided in this Section 10. The Committee may in its discretion direct Sponsor to retain in a
Participant’s account for the subsequent Offering Period any payroll deductions which are not sufficient to purchase a whole share of Common Stock or return such amount to the Participant. Any other amounts left over in a Participant’s
account after a Purchase Date shall be returned to the Participant. If the Committee does not establish different rules with respect to an Offering Period, then all amounts left over in a Participant’s account after a Purchase Date shall be
returned to the Participant.

 Section 11. RECAPITALIZATION 

Subject to any required action by the Stockholders of Sponsor, if there is any change in the outstanding shares of Common Stock or other
securities of Sponsor because of a merger, consolidation, spin-off, reorganization, recapitalization, dividend in property other than cash, extraordinary dividend whether in cash and/or other property, stock
split, reverse stock split, stock dividend, liquidating dividend, combination or reclassification of the Common Stock or other securities (including any such change in the number of shares of Common Stock or other securities effected in connection
with a change in domicile of Sponsor), or any other increase or decrease in the number of shares of Common Stock or other securities effected without receipt of consideration by Sponsor, provided that conversion of any convertible securities of
Sponsor shall not be deemed to have been “effected without receipt of consideration,” the type and number of securities covered by each option under the Plan which has not yet been exercised and the type and number of securities which have
been authorized and remain available for issuance under the Plan, as well as the maximum number of securities which may be purchased by a Participant in an Offering Period, and the price per share covered by each option under the Plan which has not
yet been exercised, shall be appropriately and proportionally adjusted by the Board, and the Board shall take any further actions which, in the exercise of its discretion, may be necessary or appropriate under the circumstances. The Board’s
determinations under this Section 11 shall be conclusive and binding on all parties. 
 Section 12. MERGER, LIQUIDATION, OTHER CORPORATE
TRANSACTIONS 
 (a) In the event of the proposed liquidation or dissolution of Sponsor, the Offering Period will terminate immediately
prior to the consummation of such proposed transaction, unless otherwise provided by the Board in its sole discretion, and all outstanding options shall automatically terminate and the amounts of all payroll deductions will be refunded without
interest to the Participants. 
 (b) In the event of a proposed sale of all or substantially all of the assets of Sponsor, or the merger or
consolidation or similar combination of Sponsor with or into another entity, then in the sole discretion of the Board, (1) each option shall be assumed or an equivalent option shall be substituted by the successor corporation or parent or
subsidiary of such successor entity, (2) on a date established by the Board on or before the date of consummation of such merger, consolidation, combination or sale, such date shall be treated as a Purchase Date, and all outstanding options
shall be exercised on such date, (3) all outstanding options shall terminate and the accumulated payroll deductions will be refunded without interest to the Participants, or (4) outstanding options shall continue unchanged. 

Section 13. TRANSFERABILITY 
 Neither
payroll deductions credited to a Participant’s bookkeeping account nor any rights to exercise an option or to receive shares of Common Stock under the Plan may be voluntarily or involuntarily assigned, transferred, pledged, or otherwise
disposed of in any way, and any attempted assignment, transfer, pledge, or other disposition shall be null and void and without effect. If a Participant in any manner attempts to transfer, assign or otherwise encumber his or her rights or interests
under the Plan, other than as permitted by the Code, such act shall be treated as an election by the Participant to discontinue participation in the Plan pursuant to Section 5(c).

 Section 14. AMENDMENT OR TERMINATION OF THE PLAN 

(a) The Plan shall continue from the Effective Date until the time that the Plan is terminated in accordance with Section 14(b). 

(b) The Board or the Committee may, in its sole discretion, insofar as permitted by law, terminate or suspend the Plan, or revise or amend it
in any respect whatsoever, except that, without approval of the Stockholders, no such revision or amendment shall increase the number of shares subject to the Plan, other than an adjustment under Section 11 of the Plan, or make other changes
for which Stockholder approval is required under Applicable Law. Upon a termination or suspension of the Plan, the Board may in its discretion (i) return without interest, the payroll deductions credited to Participants’ accounts to such
Participants or (ii) set an earlier Purchase Date with respect to an Offering Period then in progress. 
 Section 15. ADMINISTRATION 

(a) The Board has appointed the Compensation Committee of the Board to administer the Plan (the “Committee”), who will serve
for such period of time as the Board may specify and whom the Board may remove at any time. The Committee will have the authority and responsibility for the day-to-day
administration of the Plan, the authority and responsibility specifically provided in this Plan and any additional duty, responsibility and authority delegated to the Committee by the Board, which may include any of the functions assigned to the
Board in this Plan. The Committee may delegate to a sub-committee and/or to officers or employees of Sponsor the day-to-day
administration of the Plan. The Committee shall have full power and authority to adopt, amend and rescind any rules and regulations which it deems desirable and appropriate for the proper administration of the Plan, to construe and interpret the
provisions and supervise the administration of the Plan, to make factual determinations relevant to Plan entitlements and to take all action in connection with administration of the Plan as it deems necessary or advisable, consistent with the
delegation from the Board. Decisions of the Committee shall be final and binding upon all Participants. Any decision reduced to writing and signed by a majority of the members of the Committee shall be fully effective as if it had been made at a
meeting of the Committee duly held. The Company shall pay all expenses incurred in the administration of the Plan. 
 (b) In addition to such
other rights of indemnification as they may have as members of the Board or officers or employees of the Company, members of the Board and of the Committee and their delegates shall be indemnified by the Company against all reasonable expenses,
including attorneys’ fees, actually and necessarily incurred in connection with the defense of any action, suit or proceeding, or in connection with any appeal therein, to which they or any of them may be a party by reason of any action taken
or failure to act under or in connection with the Plan, or any right granted under the Plan, and against all amounts paid by them in settlement thereof (provided such settlement is approved by independent legal counsel selected by the Sponsor) or
paid by them in satisfaction of a judgment in any such action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such action, suit or proceeding that such person is liable for gross negligence, bad faith or
intentional misconduct in duties; provided, however, that within sixty (60) days after the institution of such action, suit or proceeding, such person shall offer to the Company, in writing, the opportunity at its own expense to handle and
defend the same.

 Section 16. COMMITTEE RULES FOR JURISDICTIONS OTHER THAN THE UNITED STATES 

The Committee may adopt rules or procedures relating to the operation and administration of the Plan to accommodate the specific requirements
of the laws and procedures of jurisdictions outside of the United States. Without limiting the generality of the foregoing, the Committee is specifically authorized to adopt rules and procedures regarding handling of payroll deductions or other
contributions by Participants, payment of interest, conversion of local currency, data privacy security, payroll tax, withholding procedures and handling of stock certificates which vary with local requirements; however, if such varying provisions
are not in accordance with the provisions of Section 423(b) of the Code, including but not limited to the requirement of Section 423(b)(5) of the Code that all options granted under the Plan shall have the same rights and privileges unless
otherwise provided under the Code and the regulations promulgated thereunder, then the individuals affected by such varying provisions shall be deemed to be participating under a sub-plan and not in the Plan.
The Committee may also adopt sub-plans applicable to particular Subsidiaries or locations, which sub-plans may be designed to be outside the scope of Code
Section 423 and shall be deemed to be outside the scope of Code Section 423 unless the terms of the sub-plan provide to the contrary. The rules of such
sub-plans may take precedence over other provisions of this Plan, with the exception of Section 7, but unless otherwise superseded by the terms of such sub-plan,
the provisions of this Plan shall govern the operation of such sub-plan. The Committee shall not be required to obtain the approval of the Stockholders prior to the adoption, amendment or termination of any sub-plan unless required by the laws of the jurisdiction in which Employees participating in the sub-plan are located. 

Section 17. SECURITIES LAWS REQUIREMENTS 

(a) No option granted under the Plan may be exercised to any extent unless the shares to be issued upon such exercise under the Plan are
covered by an effective registration statement pursuant to the Securities Act and the Plan is in material compliance with all applicable provisions of any applicable national, regional, state, local or other jurisdiction, including, without
limitation, the Securities Act, the Exchange Act, the rules and regulations promulgated thereunder, applicable state and foreign securities laws and the requirements of any stock exchange upon which the Shares may then be listed, subject to the
approval of counsel for the Company with respect to such compliance. If on a Purchase Date in any Offering Period hereunder, the Plan is not so registered or in such compliance, options granted under the Plan which are not in material compliance
shall not be exercised on such Purchase Date, and the Purchase Date shall be delayed until the Plan is subject to such an effective registration statement and such compliance, except that the Purchase Date shall not be delayed more than twelve
(12) months and the Purchase Date shall in no event be more than twenty-seven (27) months from the Commencement Date relating to such Offering Period. If, on the Purchase Date of any offering hereunder, as delayed to the maximum extent
permissible, the Plan is not registered and in such 

  
 11 

 
compliance, options granted under the Plan which are not in material compliance shall not be exercised and all payroll deductions accumulated during the Offering Period (reduced to the extent, if
any, that such deductions have been used to acquire shares of Common Stock) shall be returned to the Participants, without interest. The provisions of this Section 17 shall comply with the requirements of Section 423(b)(5) of the Code to
the extent applicable. 
 (b) As a condition to the exercise of an option, Sponsor may require the person exercising such option to represent
and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for Sponsor, such a representation is required by
any of the aforementioned applicable provisions of law. 
 Section 18. GOVERNMENTAL REGULATIONS 

This Plan and Sponsor’s obligation to sell and deliver shares of its stock under the Plan shall be subject to the approval of any
governmental authority required in connection with the Plan or the authorization, issuance, sale, or delivery of stock hereunder. 
 Section 19. NO
ENLARGEMENT OF EMPLOYEE RIGHTS 
 Nothing contained in this Plan shall be deemed to give any Employee or other individual the right to be
retained in the employ or service of Sponsor or any Participating Subsidiary or to interfere with the right of Sponsor or Participating Subsidiary to discharge any Employee or other individual at any time, for any reason or no reason, with or
without notice. 
 Section 20. GOVERNING LAW 

This Plan shall be governed by applicable laws of the State of Delaware without regard for the conflicts of laws provisions thereof, and other
applicable law. 
 Section 21. EFFECTIVE DATE 

This Plan shall be effective on the Effective Date, subject to approval of the Stockholders of Sponsor within twelve (12) months before or
after its date of adoption by the Board. 
 Section 22. REPORTS 

Individual accounts shall be maintained for each Participant in the Plan. Statements of account shall be made available to Participants at
least annually, which statements shall set forth the amounts of payroll deductions, the Purchase Price, the number of shares of Common Stock purchased and the remaining cash balance, if any. 

Section 23. DESIGNATION OF BENEFICIARY FOR OWNED SHARES 

With respect to shares of Common Stock purchased by the Participant pursuant to the Plan and held in an account maintained by Sponsor or its
assignee on the Participant’s behalf, the Participant may be permitted to file a written designation of beneficiary, who is to receive any shares and cash, if any, from the Participant’s account under the Plan in the event of such

  
 12 

 
Participant’s death subsequent to the end of an Offering Period but prior to delivery to him or her of such shares and cash. In addition, a Participant may file a written designation of a
beneficiary who is to receive any cash from the Participant’s account under the Plan in the event of such Participant’s death prior to the Purchase Date of an Offering Period. If a Participant is married and the designated beneficiary is
not the spouse, spousal consent shall be required for such designation to be effective to the extent required by local law. The Participant (and if required under the preceding sentence, his or her spouse) may change such designation of beneficiary
at any time by written notice. Subject to local legal requirements, in the event of a Participant’s death, Sponsor or its assignee shall deliver any shares of Common Stock and/or cash to the designated beneficiary. Subject to local law, in the
event of the death of a Participant and in the absence of a beneficiary validly designated who is living at the time of such Participant’s death, Sponsor shall deliver such shares of Common Stock and/or cash to the executor or administrator of
the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of Sponsor), Sponsor in its sole discretion, may deliver (or cause its assignee to deliver) such shares of Common Stock and/or cash to the
spouse, or to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to Sponsor, then to such other person as Sponsor may determine. The provisions of this Section 23 shall in no event
require Sponsor to violate local law, and Sponsor shall be entitled to take whatever action it reasonably concludes is desirable or appropriate in order to transfer the assets allocated to a deceased Participant’s account in compliance with
local law. 
 Section 24. ADDITIONAL RESTRICTIONS OF RULE 16b-3. 

The terms and conditions of options granted hereunder to, and the purchase of shares of Common Stock by, persons subject to Section 16 of
the Exchange Act shall comply with the applicable provisions of Rule 16b-3. This Plan shall be deemed to contain, and such options shall contain, and the shares of Common Stock issued upon exercise thereof
shall be subject to, such additional conditions and restrictions, if any, as may be required by Rule 16b-3 to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan
transactions. 
 Section 25. NOTICES 

All notices or other communications by a Participant to Sponsor or the Committee under or in connection with the Plan shall be deemed to have
been duly given when received in the form specified by Sponsor or the Committee at the location, or by the person, designated by Sponsor for the receipt thereof.
