 Exhibit 10.2 

PROTAGONIST THERAPEUTICS, INC. 

2016 EQUITY INCENTIVE PLAN 

ADOPTED BY THE BOARD OF DIRECTORS:
JULY 28, 2016 
 APPROVED BY THE STOCKHOLDERS:
JULY 31, 2016 
 EFFECTIVE DATE: JULY 28, 2016 

1. GENERAL. 
 (a)
Successor to and Continuation of Prior Plan. The Plan is intended as the successor to and continuation of the Protagonist Therapeutics, Inc. 2007 Stock Option and Incentive Plan, as amended (the “Prior
Plan”). From and after 12:01 a.m. Pacific Time on the Effective Date, no additional stock awards may be granted under the Prior Plan. All Awards granted on or after 12:01 a.m. Pacific Time on the Effective Date will be granted
under this Plan. All stock awards granted under the Prior Plan will remain subject to the terms of the Prior Plan. 
 (i) Any shares
that would otherwise remain available for future grants under the Prior Plan as of 12:01 a.m. Pacific Time on the Effective Date (the “Prior Plan’s Available Reserve”) will cease to be available under the Prior Plan at
such time. Instead, that number of shares of Common Stock equal to the Prior Plan’s Available Reserve will be added to the Share Reserve (as further described in Section 3(a) below) and be then immediately available for grants and issuance
pursuant to Stock Awards hereunder, up to the maximum number set forth in Section 3(a) below. 
 (ii) In addition, from and after
12:01 a.m. Pacific time on the Effective Date, with respect to the aggregate number of shares subject, at such time, to outstanding stock awards granted under the Prior Plan that (1) expire or terminate for any reason prior to exercise or
settlement; (2) are forfeited because of the failure to meet a contingency or condition required to vest such shares or otherwise return to the Company; or (3) are reacquired, withheld (or not issued) to satisfy a tax withholding obligation in
connection with an award or to satisfy the purchase price or exercise price of a stock award (such shares the “Returning Shares”) will immediately be added to the Share Reserve (as further described in Section 3(a) below) as
and when such a share becomes a Returning Share. 
 (b) Eligible Award Recipients. Employees, Directors and Consultants
are eligible to receive Awards. 
 (c) Available Awards. The Plan provides for the grant of the following types of
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, (vii) Performance Cash Awards, and (viii) Other
Stock Awards. 
 (d) Purpose. The 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 recipients may benefit from increases in value of the
Common Stock.

 2. ADMINISTRATION. 

(a) Administration by Board. The Board will administer the Plan. The Board may delegate administration of the 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 the 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 the Plan and Awards granted under it, and to establish, amend and revoke rules and regulations for
administration of the Plan and Awards. The Board, in the exercise of these powers, may correct any defect, omission or inconsistency in the Plan or in any Award Agreement 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 the Plan or Award fully effective. 
 (iii) To settle all controversies
regarding the Plan and Awards granted under it. 
 (iv) To accelerate, in whole or in part, the time at 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 the Plan at any
time. Except as otherwise provided in the Plan or an Award Agreement, suspension or termination of the Plan will not 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 the Plan in any respect the Board deems necessary or advisable, including,
without limitation, by adopting amendments relating to Incentive Stock Options and certain nonqualified deferred compensation under Section 409A of the Code and/or to make the Plan or Awards granted under the Plan 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. However, 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 the Plan that (A) materially increases the number of shares of Common Stock
available for issuance under the Plan, (B) materially expands the class of individuals eligible to receive Awards under the Plan, (C) materially increases the benefits accruing to Participants under the Plan, (D) materially reduces the
price at which shares of Common Stock may be issued or purchased under the Plan, (E) materially extends the term of the Plan, or 

  
 2 








 
(F) materially expands the types of Awards available for issuance under the Plan. Except as provided in the Plan (including subsection (viii) below) or an Award Agreement, no amendment
of the Plan will impair a Participant’s rights under an outstanding Award unless (1) the Company requests the consent of the affected Participant, and (2) such Participant consents in writing.

(vii) To submit any amendment to the Plan for stockholder approval, including, but not limited to, amendments to the Plan intended to
satisfy the requirements of (A) Section 162(m) of the Code regarding the exclusion of performance-based compensation from the limit on corporate deductibility of compensation paid to Covered Employees, (B) Section 422 of the Code regarding incentive
stock options or (C) Rule 16b-3. 
 (viii) To approve forms of Award Agreements for use under the Plan and to amend the terms of any
one or more Awards, including, but not limited to, amendments to provide terms more favorable to the Participant than previously provided in the Award Agreement, subject to any specified limits in the Plan that are not subject to Board discretion;
provided however, that a Participant’s rights under any Award will not be impaired by any such amendment unless (A) the Company requests the consent of the affected Participant, and (B) such Participant consents in
writing. Notwithstanding the foregoing, (1) 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, and (2) 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 the Plan or Awards. 
 (x) To adopt such procedures and
sub-plans as are necessary or appropriate to permit participation in the Plan by Employees, Directors or Consultants who are foreign nationals or employed outside the United States (provided that Board approval will not be necessary for immaterial
modifications to the Plan or any Award Agreement that are required for compliance with the laws of the relevant foreign 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 therefor of a new (1) Option or SAR, (2) Restricted Stock Award, (3) Restricted Stock Unit Award, (4) Other Stock Award, (5) cash
and/or (6) 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 the
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 the Plan to a Committee or Committees. If
administration of the Plan is delegated to a Committee, the Committee will have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee, including the power to
delegate to a subcommittee of the Committee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board will thereafter be to the Committee or subcommittee). Any delegation of
administrative powers will be reflected in resolutions, not inconsistent with the provisions of the 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 to the subcommittee. The Board may retain the authority to concurrently administer the Plan with the Committee and may, at any time, revest in the Board some or all of the powers previously
delegated. 
 (ii) Section 162(m) and Rule 16b-3 Compliance. The Committee may consist solely of two or more Outside
Directors, in accordance with Section 162(m) of the Code, or solely of two or more Non-Employee Directors, in accordance with Rule 16b-3. 

(d) Delegation to an Officer. The Board may delegate to one or more Officers the authority to do one or both of the
following (i) designate Employees who are not Officers to be recipients of Options and SARs (and, to the extent permitted by applicable law, other Stock Awards) and, to the extent permitted by applicable law, the terms of such 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 the form of Award Agreement most recently approved for use by the
Committee or the Board, unless otherwise provided in the resolutions approving the delegation authority. The Board may not delegate authority to an Officer who is acting solely in the capacity of an Officer (and not also as a Director) to
determine the Fair Market Value pursuant to Section 13(y)(iii) below. 
 (e) Effect of Board’s Decision. All
determinations, interpretations and constructions made by the Board 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 THE PLAN. 

(a) Share Reserve. Subject to Section 9(a) relating to Capitalization Adjustments, and the following sentence
regarding the annual increase, the aggregate number of shares of Common Stock that may be issued pursuant to Stock Awards will not exceed (A) 1,200,000 shares, which number is the sum of (i) the 52,925 shares subject to the Prior Plan’s
Available Reserve and (ii) an additional 1,147,075 new shares plus (B) the Returning Shares, if any, which 

  
 4 








 
become available for grant under this Plan from time to time, up to a maximum of 1,365,987 Returning Shares (such aggregate number of shares described in (A) and (B) above, the “Share
Reserve”). In addition, the Share Reserve will automatically increase on the first day of each fiscal year for a period of up to ten years, commencing on the first day of the fiscal year following the year in which the IPO Date
occurs, in an amount equal to four percent (4%) of the total number of shares of Common Stock outstanding on the last day of the preceding fiscal year. Notwithstanding the foregoing, the Board may act prior to the first day of any fiscal year
to provide that there will be no increase in the Share Reserve for such fiscal year or that the increase in the Share Reserve for such fiscal year will be a lesser number of shares of Common Stock than would otherwise occur pursuant to the preceding
sentence. 
 For clarity, the Share Reserve in this Section 3(a) is a limitation on the number of shares of Common Stock that may be issued
pursuant to the Plan. Accordingly, this Section 3(a) does not limit the granting of Stock Awards except as provided in Section 7(a). Shares may be issued in connection with a merger or acquisition as permitted by NASDAQ Listing Rule
5635(c) or, if applicable, 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 the Plan.

(b) Reversion of Shares to the Share Reserve. If a Stock Award or any portion thereof (i) expires or otherwise
terminates without all of the shares covered by such Stock Award having been issued or (ii) is settled in cash (i.e., the Participant receives cash rather than stock), such expiration, termination or settlement will not reduce (or otherwise
offset) the number of shares of Common Stock that may be available for issuance under the Plan. If any shares of Common Stock issued pursuant to a Stock Award are forfeited back to or repurchased 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 or repurchased will revert to and again become available for issuance under the Plan. Any shares reacquired 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 again become available for issuance under the Plan. 

(c) Incentive Stock Option Limit. Subject to the Share Reserve and Section 9(a) relating to Capitalization
Adjustments, the aggregate maximum number of shares of Common Stock that may be issued pursuant to the exercise of Incentive Stock Options will be 3,500,000 shares of Common Stock. 

(d) Section 162(m) Limitations. Subject to the Share Reserve and Section 9(a) relating to Capitalization Adjustments, at
such time as the Company may be subject to the applicable provisions of Section 162(m) of the Code, the following limitations will apply. 

(i) A maximum of 1,000,000 shares of Common Stock subject to Options, SARs and Other Stock Awards whose value is determined by
reference to an increase over an exercise or strike price of at least 100% of the Fair Market Value on the date any such Stock Award is granted may be granted to any Participant during any fiscal year.

(ii) A maximum of 1,000,000 shares of Common Stock subject to Performance Stock Awards may be granted to any one Participant during any
one fiscal year (whether the grant, vesting or exercise is contingent upon the attainment during the Performance Period of the Performance Goals). 

(iii) A maximum of $2,000,000 may be granted as a Performance Cash Award to any one Participant during any one fiscal year. 

  
 5 








 If a Performance Stock Award is in the form of an Option, it will count only against the
Performance Stock Award limit. If a Performance Stock Award could be paid out in cash, it will count only against the Performance Stock Award limit. 

(e) Limitation on Grants to Non-Employee Directors. The maximum number of shares of Common Stock subject to Stock
Awards granted under the Restated Plan or otherwise during any one fiscal year to any Non-Employee Director, taken together with any cash fees paid by the Company to such Non-Employee Director during such fiscal year for service on the Board, will
not exceed $500,000 in total value, or $1,000,000 with respect to a Non-Employee Director’s first year of service (calculating the value of any such Stock Awards based on the grant date fair value of such Stock Awards for financial reporting
purposes). The Board may make exceptions to the applicable limit in this Section 3(e) for individual Non-Employee Directors in extraordinary circumstances (for example, to compensate such individual for interim service in the capacity of an officer
of the Company), as the Board may determine in its discretion, provided that the Non-Employee Director receiving such additional compensation may not participate in the decision to award such compensation. 

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

(a) Eligibility for Specific Stock Awards. Incentive Stock Options may be granted only to employees of the Company or a
“parent corporation” or “subsidiary corporation” thereof (as such terms are defined in Sections 424(e) and 424(f) of the Code). Stock Awards other than Incentive Stock Options may be granted to Employees, Directors and
Consultants; provided, however, that Stock Awards may not be granted to Employees, Directors and Consultants who are providing Continuous Service only to any “parent” of the Company, as such term is defined in Rule 405, unless (i) the
stock underlying such Stock Awards is treated as “service recipient stock” under Section 409A of the Code (for example, because the Stock Awards are granted pursuant to a Transaction such as a spin off transaction), (ii) the Company, in
consultation with its legal counsel, has determined that such Stock Awards are otherwise exempt from Section 409A of the Code, or (iii) the Company, in consultation with its legal counsel, has determined that such Stock Awards comply with the
distribution requirements of Section 409A of the Code. 
 (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 years from the date of grant.

 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 Agreement will conform to (through incorporation of provisions hereof by reference in the applicable Award Agreement or otherwise) the substance of each of the following provisions: 

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

(b) Exercise Price. Subject to the provisions of 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 Transaction and in a
manner consistent with the provisions of Section 409A of the Code and, if applicable, Section 424(a) of the Code. 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 permitted methods of payment are as follows:

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

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

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

(iv) if an Option is a Nonstatutory Stock Option, by a “net exercise” arrangement pursuant to which the Company will reduce
the number of shares of Common Stock 

  
 7 








 
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 a
cash or other payment from the Participant to the extent of any remaining balance of the aggregate exercise price not satisfied by such reduction in the number of whole shares to be issued. 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 Agreement. 
 (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 Award Agreement 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, and 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 Agreement 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 will determine. 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 (and 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 Treasury Regulation 1.421-1(b)(2). If an Option is an Incentive Stock Option, such
Option may be deemed to be a Nonstatutory Stock Option as a result of such transfer. 
 (iii) Beneficiary
Designation. 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, upon
the death 

  
 8 








 
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, upon the death or the Participant, 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 Agreement 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 months following the termination of the Participant’s Continuous Service (or such longer or shorter period specified in the applicable Award Agreement) and (ii) the expiration of the term of the
Option or SAR as set forth in the Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR (as applicable) within the applicable time frame, the Option or SAR will terminate. 

(h) Extension of Termination Date. Except as otherwise provided in the applicable Award Agreement or other agreement
between the Participant and the Company, if the exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause 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 time
(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 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 Agreement. In addition, unless otherwise provided in a Participant’s Award Agreement, if the sale of any Common Stock received on
exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause) would violate the Company’s insider trading policy, then the Option or SAR 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 Agreement. 

  
 9 








 (i) Disability of Participant. Except as otherwise provided in the applicable
Award Agreement 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 (or such longer or shorter period specified in the Award Agreement) and (ii) the expiration of the term of the Option or SAR as set forth in the Award Agreement. 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 Agreement 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 the Award Agreement 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 (or such longer or shorter period specified in the Award Agreement)
and (ii) the expiration of the term of such Option or SAR as set forth in the Award Agreement. If, after the Participant’s death, the Option or SAR is not exercised within the applicable time frame, the Option or SAR (as applicable) will
terminate. 
 (k) Termination for Cause. Except as explicitly provided otherwise in a Participant’s Award Agreement
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 immediately upon such Participant’s termination
of Continuous Service, and the Participant will be prohibited from exercising his or her Option or SAR from and after the time of such 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. 

(l) Non-Exempt Employees. If an Option or SAR is granted to an Employee who is a non-exempt employee for purposes of the
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 six 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 Worker Economic Opportunity Act, (i) if such non-exempt Employee dies or suffers a Disability, (ii) upon a Corporate Transaction in which such Option or SAR is not assumed, continued, or substituted, (iii) upon
a Change in Control, or (iv) upon the Participant’s retirement (as such term may be defined in the Participant’s Award Agreement, in another agreement between the Participant and the Company, or, if no such


  
 10 








 
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 six months
following the date of grant. The foregoing provision is intended to operate so that any income derived by a non-exempt employee in connection with the exercise or vesting of an Option or SAR will be exempt from his or her regular rate of pay.
To the extent permitted and/or required for compliance with the 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 the employee’s regular rate of pay, the provisions of this Section 5(l) will apply to all Stock Awards and are hereby incorporated by reference into such Stock Award Agreements. 

6. PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS
AND SARS. 
 (a) Restricted Stock Awards. Each Restricted Stock Award Agreement 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 (i) held in book entry form subject to
the Company’s instructions until any restrictions relating to the Restricted Stock Award lapse; or (ii) 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 Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Award Agreements need not be identical. Each Restricted Stock Award Agreement 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 Agreement may be subject to
forfeiture to the Company in accordance with a vesting schedule to be determined by the Board. 
 (iii) Termination of
Participant’s Continuous Service. If a Participant’s Continuous Service terminates, the Company may receive through a forfeiture condition or a repurchase right any or all of the shares of Common Stock held by the Participant that
have not vested as of the date of termination of Continuous Service under the terms of the Restricted Stock Award Agreement. 
 (iv)
Transferability. Rights to acquire shares of Common Stock under the Restricted Stock Award Agreement will be transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Award Agreement, as
the Board will determine in its sole discretion, so long as Common Stock awarded under the Restricted Stock Award Agreement remains subject to the terms of the Restricted Stock Award Agreement. 

(v) Dividends. A Restricted Stock Award Agreement may provide that any dividends paid on Restricted Stock will be
subject to the same vesting and forfeiture restrictions as apply to the shares subject to the Restricted Stock Award to which they relate. 

  
 11 








 (b) Restricted Stock Unit Awards. Each Restricted Stock Unit Award
Agreement 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 Agreements may change from time to time, and the terms and conditions of separate
Restricted Stock Unit Award Agreements need not be identical. Each Restricted Stock Unit Award Agreement 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 Agreement. 
 (iv) Additional Restrictions. At the time of the grant of a Restricted
Stock Unit Award, the Board, as it deems appropriate, may impose such restrictions or conditions that delay the delivery of the shares of Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to a time after the vesting of
such Restricted Stock Unit Award. 
 (v) Dividend Equivalents. Dividend equivalents may be credited in respect of
shares of Common Stock covered by a Restricted Stock Unit Award, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. At the sole discretion of the Board, such dividend equivalents may be converted into
additional shares of Common Stock covered by the Restricted Stock Unit Award in such manner as determined by the Board. Any additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents will be
subject to all of the same terms and conditions of the underlying Restricted Stock Unit Award Agreement to which they relate. 
 (vi)
Termination of Participant’s Continuous Service. Except as otherwise provided in the applicable Restricted Stock Unit Award Agreement, such portion of the Restricted Stock Unit Award that has not vested will be
forfeited upon the Participant’s termination of Continuous Service. 

  
 12 








 (c) Performance Awards. 

(i) Performance Stock Awards. A Performance Stock Award is a Stock Award (covering a number of shares not in excess of that
set forth in Section 3(d)(ii) above) that is payable (including that may be granted, vest or exercised) contingent upon the attainment during a Performance Period 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 (or, if not required for compliance with Section 162(m) of the Code, the Board), in its sole discretion. In addition, to the extent permitted by applicable law and the applicable
Award Agreement, 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 (for a dollar value not in excess of that set forth in Section 3(d)(iii) above) that is payable contingent upon the attainment during a Performance Period 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 (or, if not required for compliance with Section 162(m) of the Code, the Board), 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 Board 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.

(iv) Section 162(m) Compliance. Unless otherwise permitted in compliance with the requirements of Section 162(m) of the
Code with respect to an Award intended to qualify as “performance-based compensation” thereunder, the Committee will establish the Performance Goals applicable to, and the formula for calculating the amount payable under, the Award no
later than the earlier of (A) the date 90 days after the commencement of the applicable Performance Period, and (B) the date on which 25% of the Performance Period has elapsed, and in any event at a time when the achievement of the applicable
Performance Goals remains substantially uncertain. Prior to the payment of any compensation under an Award intended to qualify as “performance-based compensation” under Section 162(m) of the Code, the Committee will certify the
extent to which any Performance Goals and any other material terms under such Award have been satisfied (other than in cases where such relate solely to the increase in the value of the Common Stock). Notwithstanding satisfaction of any completion
of any Performance Goals, the number of shares of Common Stock, Options, cash or other benefits granted, issued, retainable and/or vested under an Award on account of satisfaction of such Performance Goals may be reduced by the Committee on the
basis of such further considerations as the Committee, in its sole discretion, will determine. 
 (d) Other Stock
Awards. Other forms of Stock Awards valued in whole or in part by reference to, or otherwise based on, Common Stock, including the appreciation in value thereof (e.g., options or stock rights with an exercise price or strike price less than
100% of the Fair Market Value of the Common Stock at the time of grant) may be granted either alone or in addition to Stock Awards provided for under Section 5 and the preceding provisions of this Section 6. Subject to the provisions of the
Plan, the Board will have sole and complete authority to determine the persons to whom and the time or times at which such Other Stock Awards will be granted, the number of shares of Common Stock (or the cash equivalent thereof) to be granted
pursuant to such Other Stock Awards and all other terms and conditions of such Other Stock Awards. 

  
 13 








 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 the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock Awards; provided, however, that this
undertaking will not require the Company to register under the Securities Act the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts and at a reasonable cost, the Company
is unable to obtain from any such regulatory commission or agency the authority that counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company 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 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 date of such corporate action, unless otherwise determined by the Board, regardless of when the instrument, certificate, or letter
evidencing the Award is communicated to, or actually 

  
 14 








 
received or accepted by, the Participant. In the event that the corporate records (e.g., Board consents, resolutions or minutes) documenting the corporate action approving the grant contain
terms (e.g., exercise price, vesting schedule or number of shares) that are inconsistent with those in the Award Agreement or related grant documents as a result of a clerical error in the papering of the Award Agreement or related grant documents,
the corporate records will control and the Participant will have no legally binding right to the incorrect term in the Award Agreement or related grant documents.

(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 an Award unless and until (i) such Participant has satisfied all requirements for exercise of, or the issuance of shares of Common Stock under, the Award pursuant to its terms, and (ii) the issuance
of the Common Stock subject to such Award has been entered into the books and records of the Company. 
 (d) No Employment or
Other Service Rights. Nothing in the Plan, any Award Agreement 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 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, (ii) the service of
a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate, or (iii) the service of a Director pursuant to the bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of
the state in which the Company or the Affiliate is incorporated, as the case may be. 
 (e) 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) after the date of grant of any Award to the Participant, the Board has the right in its sole discretion to (x) 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 (y) 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 $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). 

  
 15 








 (g) Investment Assurances. The Company may require a Participant, as a
condition of exercising or acquiring Common Stock under any 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 Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the 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 (A) the issuance of the shares upon the exercise or acquisition of Common Stock under the Stock
Award has been registered under a then currently effective registration statement under the Securities Act, or (B) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the
circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with
applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock. 
 (h)
Withholding Obligations. Unless prohibited by the terms of an Award Agreement, the Company may, in its sole discretion, satisfy any federal, state or local 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
Stock Award; provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law (or such lesser amount as may be necessary to avoid classification of the Stock Award
as a liability for financial accounting purposes); (iii) withholding cash from an Award settled in cash; (iv) withholding payment from any amounts otherwise payable to the Participant; or (v) by such other method as may be set forth in the Award
Agreement. 
 (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. 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 the Plan and in accordance with applicable law. 

  
 16 








 (k) Clawback/Recovery. All Awards granted under the 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 Agreement 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 voluntary terminate employment upon a “resignation for good reason,” or for a “constructive termination” or any similar term under any plan of or agreement with the Company. 

(l) Compliance with Section 409A. Unless otherwise expressly provided for in an Award Agreement, the Plan and Award
Agreements will be interpreted to the greatest extent possible in a manner that makes the Plan and the Awards granted hereunder exempt from Section 409A of the Code, 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 not exempt from and is therefore subject to Section 409A of the Code, the Award Agreement 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 Agreement is silent on terms necessary for compliance, such terms are hereby incorporated by reference into the Award Agreement. Notwithstanding anything to the contrary in this
Plan (and unless the Award Agreement 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, 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 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 month period elapses, with the balance paid thereafter on the original schedule. 

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 the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities by which the share reserve is
to increase automatically each year pursuant to Section 3(a), (iii) 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), (iv) the class(es) and maximum number
of securities that may be awarded to any person pursuant to Sections 3(d), and (v) the class(es) and number of securities and 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. 

  
 17 








 (b) Dissolution. Except as otherwise provided in the Stock Award Agreement, in
the event of a Dissolution 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, 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 is completed but contingent on its completion. 

(c) Transactions. The following provisions will apply to Stock Awards in the event of a Transaction unless otherwise
provided in the Stock Award Agreement 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 a Stock Award. In the event of a
Transaction, then, notwithstanding any other provision of the Plan, the Board may take one or more of the following actions with respect to Stock Awards, contingent upon the closing or completion of the Transaction: 

(i) arrange for the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) to
assume or continue the Stock Award or to substitute a similar stock award for the Stock Award (including, but not limited to, an award to acquire the same consideration paid to the stockholders of the Company pursuant to the Transaction); 

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

(iii) accelerate the vesting, in whole or in part, of the Stock Award (and, if applicable, the time at which the Stock Award may be
exercised) to a date prior to the effective time of such Transaction as the Board determines (or, if the Board does not determine such a date, to the date that is five days prior to the effective date of the Transaction), with such Stock Award
terminating if not exercised (if applicable) at or prior to the effective time of the Transaction; provided, however, that the Board may require Participants to complete and deliver to the Company a notice of exercise before the effective
date of a Transaction, which exercise is contingent upon the effectiveness of such Transaction; 
 (iv) arrange for the lapse, in
whole or in part, of any reacquisition or repurchase rights held by the Company with respect to the Stock Award; 
 (v) cancel or
arrange for the cancellation of the Stock Award, to the extent not vested or not exercised prior to the effective time of the Transaction, in exchange for such cash consideration or no consideration as the Board, in its sole discretion, may consider
appropriate; and 
 (vi) make a payment, in such form as may be determined by the Board equal to the excess, if any, of (A) the value
of the property the Participant would have received upon the exercise of the Stock Award immediately prior to the effective time of the Transaction, over (B) any exercise price payable by such holder in connection with such exercise. For clarity,
this payment may be zero ($0) if the value of the property is equal to or less than the exercise price. Payments under this provision may be delayed to the same extent that payment of consideration to the holders of Common Stock in connection with
the Transaction is delayed as a result of escrows, earn outs, holdbacks or any other contingencies. 

  
 18 








 The Board need not take the same action or actions with respect to all Stock 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 a Stock Award.

(d) Change in Control. A Stock Award may be subject to additional acceleration of vesting and exercisability upon or after
a Change in Control as may be provided in the Stock Award Agreement for such Stock Award or as may be provided in any other written agreement between the Company or any Affiliate and the Participant, but in the absence of such provision, no such
acceleration will occur. 
 10. TERMINATION OR SUSPENSION OF THE
PLAN. 
 (a) The Board may suspend or terminate the Plan at any time. No Incentive Stock Option will be
granted after the tenth anniversary of the earlier of (i) the Adoption Date, or (ii) the date the Plan is approved by the stockholders of the Company. No Awards may be granted under the Plan while the Plan is suspended or after it is
terminated. 
 (b) No Impairment of Rights. Suspension or termination of the Plan will not impair rights and obligations
under any Award granted while the Plan is in effect except with the written consent of the affected Participant or as otherwise permitted in the Plan. 

11. EFFECTIVE DATE OF PLAN. 

The Plan will come into existence on the Adoption Date; provided, however, no Award may be granted prior to the IPO Date (that is, the
Effective Date). In addition, no Stock Award will be exercised (or, in the case of a Restricted Stock Award, Restricted Stock Unit Award, Performance Stock Award, or Other Stock Award, will be granted) and no Performance Cash Award will be
settled unless and until the Plan has been approved by the stockholders of the Company, which approval will be within 12 months after the date the Plan is adopted by the Board. 

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 the Plan, the following
definitions will apply to the capitalized terms indicated below: 
 (a) “Adoption Date” means the date the
Plan is adopted by the Board. 

  
 19 








 (b) “Affiliate” means, at the time of determination, any
“parent” or “subsidiary” of the Company as such terms are defined in Rule 405. 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. 

(d) “Award Agreement” means a written agreement between the Company and a Participant evidencing the terms and
conditions of an Award. 
 (e) “Board” means the Board of Directors of the Company. 

(f) “Capitalization Adjustment” means any change that is made in, or other events that occur with respect to,
the Common Stock subject to the Plan or subject to any Stock Award after the Effective 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 any similar equity restructuring transaction,
as that term is used in Statement of 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. 
 (g) “Cause” will have the meaning ascribed to such term in
any written agreement between the Participant and the Company 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) such Participant’s
commission, indictment or conviction of, or plea of no contest with respect to, any felony or crime involving dishonesty or moral turpitude; (ii) such Participant’s failure to satisfactorily perform his or her job duties as assigned by the
Board or the officers of the Company, inability to meet documented performance goals, willful neglect of his or her duties, or refusal or failure to follow the lawful and reasonable directions of the Board or the officers of the Company, provided
that the Company first provides the Participant with written notice of such conduct and 30 days to cure the conduct (if curable), and the Participant has failed to cure such conduct within such 30 day period; (iii) such Participant’s
disloyalty, gross negligence, willful misconduct, dishonesty, fraud or breach of fiduciary duty to the Company; (iv) such Participant’s violation of any rule or policy of the Company, or breach of an employment, consulting or other agreement
with the Company, which could reasonably result in direct or indirect loss, damage or injury to the Company; (v) such Participant’s disclosure of any trade secret or confidential information of the Company; (vi) such Participant’s
commission of an act which could at the discretion of the Company be reasonably deemed to constitute unfair competition with the Company or induce any customer or supplier to breach a contract with the Company; or (vii) such Participant’s
intentional acts on the part of the Participant that have generated material adverse publicity toward or about the Company. 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 or such Participant for any other purpose. 

  
 20 








 (h) “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 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, (C) on account of the acquisition of securities of the Company by any individual who is, on the IPO Date, either an executive officer or a Director (either, an “IPO Investor”) and/or any entity
in which an IPO Investor has a direct or indirect interest (whether in the form of voting rights or participation in profits or capital contributions) of more than 50% (collectively, the “IPO Entities”) or on account of the
IPO Entities continuing to hold shares that come to represent more than 50% of the combined voting power of the Company’s then outstanding securities as a result of the conversion of any class of the Company’s securities into another class
of the Company’s securities having a different number of votes per share pursuant to the conversion provisions set forth in the Company’s Amended and Restated Certificate of Incorporation; or (D) 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 more than 50% of the combined outstanding voting power of the surviving Entity in such merger, consolidation or similar transaction or (B) more than 50% 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; provided, however, that a merger, consolidation or similar transaction will not constitute a Change in Control under this prong of the definition if the outstanding voting securities representing more than 50% of the combined
voting power of the surviving Entity or its parent are owned by the IPO Entities; 

  
 21 








 (iii) there is consummated a sale, lease, exclusive 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; provided, however, that a sale, lease, exclusive license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries will not constitute a Change
in Control under this prong of the definition if the outstanding voting securities representing more than 50% of the combined voting power of the acquiring Entity or its parent are owned by the IPO Entities; or 

(iv) individuals who, on the date the Plan is adopted by the Board, 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 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. To the extent 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 Treasury Regulations 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. 
 (i) “Code” means the Internal Revenue Code of 1986, as amended, including any
applicable regulations and guidance thereunder. 
 (j) “Committee” means a committee of one or more Directors
to whom authority has been delegated by the Board in accordance with Section 2(c).

corporation.

an Affiliate to render consulting or advisory services and is compensated for such 

  
 22 








 
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 the Plan. Notwithstanding the foregoing, a person is treated as a Consultant under this Plan only if a Form S-8 Registration Statement under the Securities
Act is available to register either the offer or the sale of the Company’s securities to such person. 
 (n)
“Continuous Service” means that the Participant’s service with the Company or an Affiliate, whether as an Employee, Director or Consultant, is not interrupted or terminated. A change in the capacity in which the
Participant renders service to the Company or an Affiliate as an Employee, Director or Consultant or a change in the Entity for which the Participant renders such service, provided that there is no interruption or termination of the
Participant’s service with the Company or an Affiliate, will not terminate a Participant’s Continuous Service; provided, however, that 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. 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. 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. Notwithstanding the foregoing, a leave of absence will be treated as Continuous Service for purposes of vesting in an Award only to such extent as may be provided in the Company’s
leave of absence policy, in the written terms of any leave of absence agreement or policy applicable to the Participant, or as otherwise required by law. In addition, to the extent 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
Treasury Regulation Section 1.409A-1(h) (without regard to any alternative definition thereunder). 
 (o) “Corporate
Transaction” means the consummation, in a single transaction or in a series of related transactions, of any one or more of the following events: 

(i) a sale or other disposition of all or substantially all, as determined by the Board, in its sole discretion, of the consolidated
assets of the Company and its Subsidiaries; 
 (ii) a sale or other disposition of more than 50% of the outstanding securities of the
Company; 
 (iii) a merger, consolidation or similar transaction following which the Company is not the surviving corporation; or

 (iv) a merger, consolidation or similar transaction following which the Company is the surviving corporation but the shares of
Common Stock outstanding immediately preceding the merger, consolidation or similar transaction are converted or exchanged by virtue of the merger, consolidation or similar transaction into other property, whether in the form of securities, cash or
otherwise.

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) “Dissolution” means when the Company, after having executed a certificate of dissolution with
the State of Delaware, has completely wound up its affairs. Conversion of the Company into a Limited Liability Company (or any other pass-through entity) will not be considered a “Dissolution” for purposes of the Plan. 

(t) “Effective Date” means the effective date of this Plan, which is the IPO Date.

Director, or payment of a fee for such services, will not cause a Director to be considered an “Employee” for purposes of the Plan.

the date of determination, as reported in a source the Board deems reliable. 

  
 24 








 (ii) Unless otherwise provided by the Board, if there is no closing sales price for the
Common Stock on the date of determination, then the Fair Market Value will be the closing selling price on the last preceding date for which such quotation exists.

manner that complies with Sections 409A and 422 of the Code.

 ATTACHMENT I 

OPTION AGREEMENT 







 PROTAGONIST THERAPEUTICS, INC. 

2016 EQUITY INCENTIVE PLAN 

OPTION AGREEMENT 

(INCENTIVE STOCK OPTION OR NONSTATUTORY STOCK
OPTION) 
 Pursuant to your Stock Option Grant Notice (“Grant Notice”) and this Option Agreement,
Protagonist Therapeutics, Inc. (the “Company”) has granted you an option under its 2016 Equity Incentive Plan (the “Plan”) to purchase the number of shares of the Company’s Common Stock indicated
in your Grant Notice at the exercise price indicated in your Grant Notice. The option is granted to you effective as of the date of grant set forth in the Grant Notice (the “Date of Grant”). If there is any conflict
between the terms in this Option Agreement and the Plan, the terms of the Plan will control. Capitalized terms not explicitly defined in this Option Agreement or in the Grant Notice but defined in the Plan will have the same definitions as in the
Plan. 
 The details of your option, in addition to those set forth in the Grant Notice and the Plan, are as follows: 

1. VESTING. Subject to the provisions contained herein, your option will vest as provided in your Grant
Notice. Vesting will cease upon the termination of your Continuous Service. 
 2. NUMBER OF
SHARES AND EXERCISE PRICE. The number of shares of Common Stock subject to your option and your exercise price per share in your Grant Notice will be adjusted for Capitalization
Adjustments. 
 3. EXERCISE RESTRICTION FOR NON-EXEMPT
EMPLOYEES. If you are an Employee eligible for overtime compensation under the Fair Labor Standards Act of 1938, as amended (that is, a “Non-Exempt Employee”), and except as otherwise provided in the
Plan, you may not exercise your option until you have completed at least six (6) months of Continuous Service measured from the Date of Grant, even if you have already been an employee for more than six (6) months. Consistent with the provisions of
the Worker Economic Opportunity Act, you may exercise your option as to any vested portion prior to such six (6) month anniversary in the case of (i) your death or disability, (ii) a Corporate Transaction in which your option is not assumed,
continued or substituted, (iii) a Change in Control or (iv) your termination of Continuous Service on your “retirement” (as defined in the Company’s benefit plans).

4. METHOD OF PAYMENT. You must pay the full amount of the exercise price for
the shares you wish to exercise. You may pay the exercise price in cash or by check, bank draft or money order payable to the Company or in any other manner permitted by your Grant Notice, which may include one or more of the
following: 
 (a) Provided that at the time of exercise the Common Stock is publicly traded, pursuant to a program developed under
Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to
the Company from the sales proceeds. This manner of payment is also known as a “broker-assisted exercise”, “same day sale”, or “sell to cover”. 

(b) Provided that at the time of exercise the Common Stock is publicly traded, by delivery to the Company (either by actual delivery or
attestation) of already-owned shares of Common 

  
 1. 








 
Stock that are owned free and clear of any liens, claims, encumbrances or security interests, and that are valued at Fair Market Value on the date of exercise. “Delivery” for these
purposes, in the sole discretion of the Company at the time you exercise your option, will include delivery to the Company of your attestation of ownership of such shares of Common Stock in a form approved by the Company. You may not exercise
your option by delivery to the Company of Common Stock if doing so would violate the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock. 

(c) If this option is a Nonstatutory Stock Option, subject to the consent of the Company at the time of exercise, by a “net
exercise” arrangement pursuant to which the Company will reduce the number of shares of Common Stock issued upon exercise of your option by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise
price. You must pay any remaining balance of the aggregate exercise price not satisfied by the “net exercise” in cash or other permitted form of payment. Shares of Common Stock will no longer be outstanding under your option and
will not be exercisable thereafter if those shares (i) are used to pay the exercise price pursuant to the “net exercise,” (ii) are delivered to you as a result of such exercise, and (iii) are withheld to satisfy your tax withholding
obligations. 
 5. WHOLE SHARES. You may exercise your option only for whole shares of
Common Stock. 
 6. SECURITIES LAW COMPLIANCE. In no event may you exercise
your option unless the shares of Common Stock issuable upon exercise are then registered under the Securities Act or, if not registered, the Company has determined that your exercise and the issuance of the shares would be exempt from the
registration requirements of the Securities Act. The exercise of your option also must comply with all other applicable laws and regulations governing your option, and you may not exercise your option if the Company determines that such
exercise would not be in material compliance with such laws and regulations (including any restrictions on exercise required for compliance with Treas. Reg. 1.401(k)-1(d)(3), if applicable). 

7. TERM. You may not exercise your option before the Date of Grant or after the expiration of the
option’s term. The term of your option expires, subject to the provisions of Sections 5(h) and 9(c) of the Plan, upon the earliest of the following: 

(a) immediately upon the termination of your Continuous Service for Cause; 

(b) three (3) months after the termination of your Continuous Service for any reason other than Cause, your Disability or your death
(except as otherwise provided in Section 7(d) below); provided, however, that if during any part of such three (3) month period your option is not exercisable solely because of the condition set forth in the section above relating to
“Securities Law Compliance,” your option will not expire until the earlier of the Expiration Date or until it has been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service; provided
further, that if (i) you are a Non-Exempt Employee, (ii) your Continuous Service terminates within six (6) months after the Date of Grant, and (iii) you have vested in a portion of your option at the time of your termination of Continuous
Service, your option will not expire until the earlier of (x) the later of (A) the date that is seven (7) months after the Date of Grant, and (B) the date that is three (3) months after the termination of your Continuous Service, and (y) the
Expiration Date; 
 (c) twelve (12) months after the termination of your Continuous Service due to your Disability (except as
otherwise provided in Section 7(d)) below; 

  
 2. 








 (d) eighteen (18) months after your death if you die either during your Continuous Service
or within three (3) months after your Continuous Service terminates for any reason other than Cause; 
 (e) the Expiration Date
indicated in your Grant Notice; or 
 (f) the day before the tenth (10th) anniversary of the Date of Grant. 

If your option is an Incentive Stock Option, note that to obtain the federal income tax advantages associated with an Incentive Stock Option,
the Code requires that at all times beginning on the Date of Grant and ending on the day three (3) months before the date of your option’s exercise, you must be an employee of the Company or an Affiliate, except in the event of your death or
Disability. The Company has provided for extended exercisability of your option under certain circumstances for your benefit but cannot guarantee that your option will necessarily be treated as an Incentive Stock Option if you continue to
provide services to the Company or an Affiliate as a Consultant or Director after your employment terminates or if you otherwise exercise your option more than three (3) months after the date your employment with the Company or an Affiliate
terminates. 
 8. EXERCISE. 

(a) You may exercise the vested portion of your option (and the unvested portion of your option if your Grant Notice so permits) during
its term by (i) delivering a Notice of Exercise (in a form designated by the Company) or completing such other documents and/or procedures designated by the Company for exercise and (ii) paying the exercise price and any applicable withholding taxes
to the Company’s Secretary, stock plan administrator, or such other person as the Company may designate, together with such additional documents as the Company may then require. 

(b) By exercising your option you agree that, as a condition to any exercise of your option, the Company may require you to enter into
an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (i) the exercise of your option, (ii) the lapse of any substantial risk of forfeiture to which the shares of Common
Stock are subject at the time of exercise, or (iii) the disposition of shares of Common Stock acquired upon such exercise. 
 (c) If
your option is an Incentive Stock Option, by exercising your option you agree that you will notify the Company in writing within fifteen (15) days after the date of any disposition of any of the shares of the Common Stock issued upon exercise of
your option that occurs within two (2) years after the Date of Grant or within one (1) year after such shares of Common Stock are transferred upon exercise of your option. 

(d) [By exercising your option you agree that you will not sell, dispose of, transfer, make any short sale of, grant any option for the
purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale with respect to any shares of Common Stock or other securities of the Company held by you, for a period of one hundred eighty (180) days following
the effective date of a registration statement of the Company filed under the Securities Act or such longer period as the underwriters or the Company will request to facilitate compliance with FINRA Rule 2241 or any successor or similar rules or
regulation (the “Lock-Up Period”); provided, however, that nothing contained in this Section will prevent the exercise of a repurchase option, if any, in favor of the Company during the Lock-Up Period. You
further agree to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriters that are consistent with the foregoing or that are necessary to give further effect thereto. In order to enforce the
foregoing covenant, the Company may 

  
 3. 








 
impose stop-transfer instructions with respect to your shares of Common Stock until the end of such period. You also agree that any transferee of any shares of Common Stock (or other securities)
of the Company held by you will be bound by this Section 8(d). The underwriters of the Company’s stock are intended third party beneficiaries of this Section 8(d) and will have the right, power and authority to enforce the provisions hereof as
though they were a party hereto.]2 
 9.
TRANSFERABILITY. Except as otherwise provided in this Section 9, your option is not transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you.

(a) Certain Trusts. Upon receiving written permission from the Board or its duly authorized designee, you may transfer your
option to a trust if you are considered to be the sole beneficial owner (determined under Section 671 of the Code and applicable state law) while the option is held in the trust. You and the trustee must enter into transfer and other agreements
required by the Company.
 (b) Domestic Relations Orders. Upon receiving written permission from the Board or its duly
authorized designee, and provided that you and the designated transferee enter into transfer and other agreements required by the Company, you may transfer your option pursuant to the terms of a domestic relations order, official marital settlement
agreement or other divorce or separation instrument as permitted by Treasury Regulation 1.421-1(b)(2) that contains the information required by the Company to effectuate the transfer. You are encouraged to discuss the proposed terms of any
division of this option with the Company prior to finalizing the domestic relations order or marital settlement agreement to help ensure the required information is contained within the domestic relations order or marital settlement
agreement. If this option is an Incentive Stock Option, this option may be deemed to be a Nonstatutory Stock Option as a result of such transfer. 

(c) Beneficiary Designation. Upon receiving written permission from the Board or its duly authorized designee, you may, by
delivering written notice to the Company, in a form approved by the Company and any broker designated by the Company to handle option exercises, designate a third party who, on your death, will thereafter be entitled to exercise this option and
receive the Common Stock or other consideration resulting from such exercise. In the absence of such a designation, your executor or administrator of your estate will be entitled to exercise this option and receive, on behalf of your estate,
the Common Stock or other consideration resulting from such exercise. 
 10. OPTION NOT
A SERVICE CONTRACT. Your option is not an employment or service contract, and nothing in your option will be deemed to create in any way whatsoever any obligation on your part to continue in the
employ of the Company or an Affiliate, or of the Company or an Affiliate to continue your employment. In addition, nothing in your option will obligate the Company or an Affiliate, their respective shareholders, boards of directors, officers or
employees to continue any relationship that you might have as a Director or Consultant for the Company or an Affiliate. 
 11.
WITHHOLDING OBLIGATIONS. 
 (a) At the time you exercise your option, in whole or in part, and at
any time thereafter as requested by the Company, you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “same day sale” pursuant to a
program developed under Regulation T as promulgated by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate,
if any, which arise in connection with the exercise of your option.
  

	2 	For inclusion only in any grants made during lock-up period. 


  
 4. 








 (b) If this option is a Nonstatutory Stock Option, then upon your request and subject to
approval by the Company, and compliance with any applicable legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole shares of
Common Stock having a Fair Market Value, determined by the Company as of the date of exercise, not in excess of the minimum amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid classification of your option
as a liability for financial accounting purposes). Notwithstanding the filing of such election, shares of Common Stock shall be withheld solely from fully vested shares of Common Stock determined as of the date of exercise of your option that
are otherwise issuable to you upon such exercise. Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility. 

(c) You may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate are
satisfied. Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company will have no obligation to issue a certificate for such shares of Common Stock or release such shares of Common
Stock from any escrow provided for herein, if applicable, unless such obligations are satisfied. 
 12. TAX
CONSEQUENCES. You hereby agree that the Company does not have a duty to design or administer the Plan or its other compensation programs in a manner that minimizes your tax liabilities. You will not make any claim
against the Company, or any of its Officers, Directors, Employees or Affiliates related to tax liabilities arising from your option or your other compensation. In particular, you acknowledge that this option is exempt from Section 409A of the Code
only if the exercise price per share specified in the Grant Notice is at least equal to the “fair market value” per share of the Common Stock on the Date of Grant and there is no other impermissible deferral of compensation associated with
the option. 
 13. NOTICES. Any notices provided for in your option or the Plan will be given in writing
(including electronically) and will be deemed effectively given upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last
address you provided to the Company. The Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan and this option by electronic means or to request your consent to participate in the Plan by
electronic means. By accepting this option, you consent to receive such documents by electronic delivery and to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party
designated by the Company. 
 14. GOVERNING PLAN DOCUMENT. Your option is
subject to all the provisions of the Plan, the provisions of which are hereby made a part of your option, and is further subject to all interpretations, amendments, rules and regulations, which may from time to time be promulgated and adopted
pursuant to the Plan. If there is any conflict between the provisions of your option and those of the Plan, the provisions of the Plan will control. In addition, your option (and any compensation paid or shares issued under your option) is
subject to recoupment in accordance with The Dodd–Frank Wall Street Reform and Consumer Protection Act and any implementing regulations thereunder, any clawback policy adopted by the Company and any compensation recovery policy otherwise
required by applicable law. No recovery of compensation under such a clawback policy will be an event giving rise to a right to voluntarily terminate employment upon a resignation for “good reason,” or for a “constructive
termination” or any similar term under any plan of or agreement with the Company. 

  
 5. 








 15. OTHER DOCUMENTS. You hereby
acknowledge receipt of and the right to receive a document providing the information required by Rule 428(b)(1) promulgated under the Securities Act, which includes the Plan prospectus. In addition, you acknowledge receipt of the Company’s
policy permitting certain individuals to sell shares only during certain “window” periods and the Company’s insider trading policy, in effect from time to time. 

16. EFFECT ON OTHER EMPLOYEE BENEFIT
PLANS. The value of this option will not be included as compensation, earnings, salaries, or other similar terms used when calculating your benefits under any employee benefit plan sponsored by the Company or
any Affiliate, except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any of the Company’s or any Affiliate’s employee benefit plans. 

17. VOTING RIGHTS. You will not have voting or any other rights as a
shareholder of the Company with respect to the shares to be issued pursuant to this option until such shares are issued to you. Upon such issuance, you will obtain full voting and other rights as a shareholder of the Company. Nothing
contained in this option, and no action taken pursuant to its provisions, will create or be construed to create a trust of any kind or a fiduciary relationship between you and the Company or any other person. 

18. SEVERABILITY. If all or any part of this Option Agreement or the Plan is declared by any
court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity will not invalidate any portion of this Option Agreement or the Plan not declared to be unlawful or invalid. Any Section of this Option Agreement (or
part of such a Section) so declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid. 

19. MISCELLANEOUS. 

(a) The rights and obligations of the Company under your option will be transferable to any one or more persons or entities, and all
covenants and agreements hereunder will inure to the benefit of, and be enforceable by the Company’s successors and assigns. 

(b) You agree upon request to execute any further documents or instruments necessary or desirable in the sole determination of the
Company to carry out the purposes or intent of your option. 
 (c) You acknowledge and agree that you have reviewed your option in
its entirety, have had an opportunity to obtain the advice of counsel prior to executing and accepting your option, and fully understand all provisions of your option. 

(d) This Option Agreement will be subject to all applicable laws, rules, and regulations, and to such approvals by any governmental
agencies or national securities exchanges as may be required. 
 (e) All obligations of the Company under the Plan and this Option
Agreement will be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the
Company.

 PROTAGONIST THERAPEUTICS, INC. 

2016 EQUITY INCENTIVE PLAN 

RESTRICTED STOCK UNIT AGREEMENT 

Pursuant to the Restricted Stock Unit Grant Notice (the “Grant Notice”) and this Restricted Stock Unit Agreement (the
“Award Agreement”) and in consideration of your services, Protagonist Therapeutics, Inc. (the “Company”) has awarded you (“Participant”) a Restricted Stock Unit Award (the
“Award”) pursuant to Section 11 of the Company’s 2016 Equity Incentive Plan (the “Plan”) for the number of Restricted Stock Units/shares indicated in the Grant Notice. Capitalized terms not
explicitly defined in this Award Agreement or the Grant Notice shall have the same meanings given to them in the Plan. The terms of your Award, in addition to those set forth in the Grant Notice, are as follows. 

1. GRANT OF THE AWARD. This Award represents the right to be issued
on a future date one (1) share of Common Stock for each Restricted Stock Unit that vests on the applicable vesting date(s) (subject to any adjustment under Section 3 below) as indicated in the Grant Notice. As of the Date of Grant, the Company will
credit to a bookkeeping account maintained by the Company for your benefit (the “Account”) the number of Restricted Stock Units/shares of Common Stock subject to the Award. This Award was granted in consideration of your
services to the Company. Except as otherwise provided herein, you will not be required to make any payment to the Company or an Affiliate (other than services to the Company or an Affiliate) with respect to your receipt of the Award, the vesting of
the Stock Units or the delivery of the Company’s Common Stock to be issued in respect of the Award. Notwithstanding the foregoing, the Company reserves the right to issue you the cash equivalent of Common Stock, in part or in full satisfaction
of the delivery of Common Stock upon vesting of your Stock Units, and, to the extent applicable, references in this Award Agreement and the Grant Notice to Common Stock issuable in connection with your Stock Units will include the potential issuance
of its cash equivalent pursuant to such right. 
 2. VESTING. Subject to the limitations contained herein, your
Award will vest, if at all, in accordance with the vesting schedule provided in the Grant Notice, provided that vesting will cease upon the termination of your Continuous Service. Upon such termination of your Continuous Service, the Restricted
Stock Units/shares of Common Stock credited to the Account that were not vested on the date of such termination will be forfeited at no cost to the Company and you will have no further right, title or interest in or to such underlying shares of
Common Stock. 
 3. NUMBER OF SHARES. The number of Restricted Stock Units/shares
subject to your Award may be adjusted from time to time for Capitalization Adjustments, as provided in the Plan. Any additional Restricted Stock Units, shares, cash or other property that becomes subject to the Award pursuant to this Section 3, if
any, shall be subject, in a manner determined by the Board, to the same forfeiture restrictions, restrictions on transferability, and time and manner of delivery as applicable to the other Restricted Stock Units and shares covered by your Award.
Notwithstanding the provisions of this Section 3, no fractional shares or rights for fractional shares of Common Stock shall be created pursuant to this Section 3. Any fraction of a share will be rounded down to the nearest whole share. 

4. SECURITIES LAW COMPLIANCE. You may not be issued any Common Stock
under your Award unless the shares of Common Stock underlying the Restricted Stock Units are either (i) then registered under the Securities Act, or (ii) the Company has determined that such issuance would be exempt from the registration
requirements of the Securities Act. Your Award must also comply with other applicable laws and regulations governing the Award, and you shall not receive such Common Stock if the Company determines that such receipt would not be in material
compliance with such laws and regulations. 

  
 1. 








 5. TRANSFER RESTRICTIONS. Prior to the
time that shares of Common Stock have been delivered to you, you may not transfer, pledge, sell or otherwise dispose of this Award or the shares issuable in respect of your Award, except as expressly provided in this Section 5. For example, you may
not use shares that may be issued in respect of your Restricted Stock Units as security for a loan. The restrictions on transfer set forth herein will lapse upon delivery to you of shares in respect of your vested Restricted Stock Units.
Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your death, shall thereafter be entitled to receive any distribution of Common
Stock to which you were entitled at the time of your death pursuant to this Award Agreement. In the absence of such a designation, your legal representative will be entitled to receive, on behalf of your estate, such Common Stock or other
consideration. 
 (a) Death. Your Award is transferable by will and by the laws of descent and distribution. At your death, vesting
of your Award will cease and your executor or administrator of your estate shall be entitled to receive, on behalf of your estate, any Common Stock or other consideration that vested but was not issued before your death. 

(b) Domestic Relations Orders. Upon receiving written permission from the Board or its duly authorized designee, and provided that you
and the designated transferee enter into transfer and other agreements required by the Company, you may transfer your right to receive the distribution of Common Stock or other consideration hereunder, pursuant to a domestic relations order,
official marital settlement agreement or other divorce or separation instrument that contains the information required by the Company to effectuate the transfer. You are encouraged to discuss the proposed terms of any division of this Award with the
Company General Counsel prior to finalizing the domestic relations order or marital settlement agreement to verify that you may make such transfer, and if so, to help ensure the required information is contained within the domestic relations order
or marital settlement agreement. 
 6. DATE OF ISSUANCE. 

(a) The issuance of shares in respect of the Restricted Stock Units is intended to comply with Treasury Regulations Section 1.409A-1(b)(4) and
will be construed and administered in such a manner. Subject to the satisfaction of the withholding obligations set forth in this Award Agreement, in the event one or more Restricted Stock Units vests, the Company shall issue to you one (1) share of
Common Stock for each Restricted Stock Unit that vests on the applicable vesting date(s) (subject to any adjustment under Section 3 above). The issuance date determined by this paragraph is referred to as the “Original Issuance
Date”. 
 (b) If the Original Issuance Date falls on a date that is not a business day, delivery shall instead occur on the
next following business day. In addition, if: 
 (i) the Original Issuance Date does not occur (1) during an “open window
period” applicable to you, as determined by the Company in accordance with the Company’s then-effective policy on trading in Company securities, or (2) on a date when you are otherwise permitted to sell shares of Common Stock on an
established stock exchange or stock market (including but not limited to under a previously established written trading plan that meets the requirements of Rule 10b5-1 under the Exchange Act and was entered into in compliance with the Company’s
policies (a “10b5-1 Plan”)), and  
 (ii) either (1) Withholding Taxes do not apply, or (2) the
Company decides, prior to the Original Issuance Date, (A) not to satisfy the Withholding Taxes by withholding shares of 

  
 2. 








 
Common Stock from the shares otherwise due, on the Original Issuance Date, to you under this Award, and (B) not to permit you to enter into a “same day sale” commitment with a
broker-dealer pursuant to Section 11 of this Agreement (including but not limited to a commitment under a 10b5-1 Plan) and (C) not to permit you to pay the Withholding Taxes in cash or from other compensation otherwise payable to you by the Company,

 then the shares that would otherwise be issued to you on the Original Issuance Date will not be delivered on such Original
Issuance Date and will instead be delivered on the first business day when you are not prohibited from selling shares of the Company’s Common Stock in the open public market, but in no event later than December 31 of the calendar year in
which the Original Issuance Date occurs (that is, the last day of your taxable year in which the Original Issuance Date occurs), or, if and only if permitted in a manner that complies with Treasury Regulations Section 1.409A-1(b)(4), no later
than the date that is the 15th day of the third calendar month of the applicable year following the year in which the shares of Common Stock under this Award are no longer subject to a “substantial risk of forfeiture” within the meaning of
Treasury Regulations Section 1.409A-1(d). 
 (c) The form of delivery of the shares of Common Stock in respect of your Award (e.g., a
stock certificate or electronic entry evidencing such shares) shall be determined by the Company. 
 7. DIVIDENDS.
You shall receive no benefit or adjustment to your Award with respect to any cash dividend, stock dividend or other distribution that does not result from a Capitalization Adjustment; provided, however, that this sentence will not apply with
respect to any shares of Common Stock that are delivered to you in connection with your Award after such shares have been delivered to you. 

8. RESTRICTIVE LEGENDS. The shares of Common Stock issued under your Award shall be endorsed with
appropriate legends as determined by the Company. 
 9. EXECUTION OF DOCUMENTS.
You hereby acknowledge and agree that the manner selected by the Company by which you indicate your consent to your Grant Notice is also deemed to be your execution of your Grant Notice and of this Award Agreement. You further agree that such
manner of indicating consent may be relied upon as your signature for establishing your execution of any documents to be executed in the future in connection with your Award. 

10. AWARD NOT A SERVICE CONTRACT. 

(a) Nothing in this Award Agreement (including, but not limited to, the vesting of your Award or the issuance of the shares subject to your
Award), the Plan or any covenant of good faith and fair dealing that may be found implicit in this Award Agreement or the Plan shall: (i) confer upon you any right to continue in the employ of, or affiliation with, the Company or an Affiliate; (ii)
constitute any promise or commitment by the Company or an Affiliate regarding the fact or nature of future positions, future work assignments, future compensation or any other term or condition of employment or affiliation; (iii) confer any right or
benefit under this Award Agreement or the Plan unless such right or benefit has specifically accrued under the terms of this Award Agreement or Plan; or (iv) deprive the Company of the right to terminate you at will and without regard to any future
vesting opportunity that you may have. 
 (b) The Company has the right to reorganize, sell, spin-out or otherwise restructure one or more
of its businesses or Affiliates at any time or from time to time, as it deems appropriate (a “reorganization”). Such a reorganization could result in the termination of your Continuous Service, or the termination of Affiliate
status of your employer and the loss of benefits available to you under this 

  
 3. 








 
Award Agreement, including but not limited to, the termination of the right to continue vesting in the Award. This Award Agreement, the Plan, the transactions contemplated hereunder and the
vesting schedule set forth herein or any covenant of good faith and fair dealing that may be found implicit in any of them do not constitute an express or implied promise of continued engagement as an employee or consultant for the term of this
Award Agreement, for any period, or at all, and shall not interfere in any way with the Company’s right to conduct a reorganization. 

11. WITHHOLDING OBLIGATIONS. 

(a) On each vesting date, and on or before the time you receive a distribution of the shares underlying your Restricted Stock Units, and at
any other time as reasonably requested by the Company in accordance with applicable tax laws, you hereby authorize any required withholding from the Common Stock issuable to you and/or otherwise agree to make adequate provision in cash for any sums
required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or any Affiliate that arise in connection with your Award (the “Withholding Taxes”). Additionally, the Company or any
Affiliate may, in its sole discretion, satisfy all or any portion of the Withholding Taxes obligation relating to your Award by any of the following means or by a combination of such means: (i) withholding from any compensation otherwise payable to
you by the Company or an Affiliate; (ii) causing you to tender a cash payment; (iii) permitting or requiring you to enter into a “same day sale” commitment, if applicable, with a broker-dealer that is a member of the Financial Industry
Regulatory Authority (a “FINRA Dealer”) whereby you irrevocably elect to sell a portion of the shares to be delivered in connection with your Restricted Stock Units to satisfy the Withholding Taxes and whereby the FINRA
Dealer irrevocably commits to forward the proceeds necessary to satisfy the Withholding Taxes directly to the Company and/or its Affiliates; or (iv) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to
you in connection with the Award with a Fair Market Value (measured as of the date shares of Common Stock are issued to pursuant to Section 6) equal to the amount of such Withholding Taxes; provided, however, that the number of such
shares of Common Stock so withheld will not exceed the amount necessary to satisfy the Company’s required tax withholding obligations using the minimum statutory withholding rates for federal, state, local and, if applicable, foreign tax
purposes, including payroll taxes, that are applicable to supplemental taxable income; and provided, further, that to the extent necessary to qualify for an exemption from application of Section 16(b) of the Exchange Act, if applicable, such
share withholding procedure will be subject to the express prior approval of the Company’s Compensation Committee.
 (b) Unless the tax
withholding obligations of the Company and/or any Affiliate are satisfied, the Company shall have no obligation to deliver to you any Common Stock or other consideration pursuant to this Award. 

(c) In the event the Company’s obligation to withhold arises prior to the delivery to you of Common Stock or it is determined after the
delivery of Common Stock to you that the amount of the Company’s withholding obligation was greater than the amount withheld by the Company, you agree to indemnify and hold the Company harmless from any failure by the Company to withhold the
proper amount. 
 12. TAX CONSEQUENCES. The Company has no duty or obligation to minimize the
tax consequences to you of this Award and shall not be liable to you for any adverse tax consequences to you arising in connection with this Award. You are hereby advised to consult with your own personal tax, financial and/or legal advisors
regarding the tax consequences of this Award and by signing the Grant Notice, you have agreed that you have done so or knowingly and voluntarily declined to do so. You understand that you (and not the Company) shall be responsible for your own tax
liability that may arise as a result of this investment or the transactions contemplated by this Award Agreement. 

  
 4. 








 13. UNSECURED OBLIGATION. Your Award is unfunded, and
as a holder of a vested Award, you shall be considered an unsecured creditor of the Company with respect to the Company’s obligation, if any, to issue shares or other property pursuant to this Award Agreement. You shall not have voting or any
other rights as a stockholder of the Company with respect to the shares to be issued pursuant to this Award Agreement until such shares are issued to you pursuant to Section 6 of this Award Agreement. Upon such issuance, you will obtain full voting
and other rights as a stockholder of the Company. Nothing contained in this Award Agreement, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind or a fiduciary relationship between you and the
Company or any other person. 
 14. NOTICES. Any notice or request required or permitted
hereunder shall be given in writing to each of the other parties hereto and shall be deemed effectively given on the earlier of (i) the date of personal delivery, including delivery by express courier, or delivery via electronic means, or (ii) the
date that is five (5) days after deposit in the United States Post Office (whether or not actually received by the addressee), by registered or certified mail with postage and fees prepaid, addressed at the following addresses, or at such other

 15. HEADINGS. The headings of the Sections in this Award Agreement
are inserted for convenience only and shall not be deemed to constitute a part of this Award Agreement or to affect the meaning of this Award Agreement. 

16. ADDITIONAL ACKNOWLEDGEMENTS. You hereby consent and
acknowledge that: 
 (a) Participation in the Plan is voluntary and therefore you must accept the terms and conditions of the Plan and this
Award Agreement and Grant Notice as a condition to participating in the Plan and receipt of this Award. This Award and any other awards under the Plan are voluntary and occasional and do not create any contractual or other right to receive
future awards or other benefits in lieu of future awards, even if similar awards have been granted repeatedly in the past. All determinations with respect to any such future awards, including, but not limited to, the time or times when such awards
are made, the size of such awards and performance and other conditions applied to the awards, will be at the sole discretion of the Company. 

(b) The future value of your Award is unknown and cannot be predicted with certainty. You do not have, and will not assert, any claim or
entitlement to compensation, indemnity or damages arising from the termination of this Award or diminution in value of this Award and you irrevocably release the Company, its Affiliates and, if applicable, your employer, if different from the
Company, from any such claim that may arise. 
 (c) The rights and obligations of the Company under your Award shall be transferable by the
Company to any one or more persons or entities, and all covenants and agreements hereunder shall inure to the benefit of, and be enforceable by, the Company’s successors and assigns. 

  
 5. 








 (d) You agree upon request to execute any further documents or instruments necessary or desirable
in the sole determination of the Company to carry out the purposes or intent of your Award. 
 (e) You acknowledge and agree that you have
reviewed your Award in its entirety, have had an opportunity to obtain the advice of counsel prior to executing and accepting your Award and fully understand all provisions of your Award. 

(f) This Award Agreement shall be subject to all applicable laws, rules, and regulations, and to such approvals by any governmental agencies
or national securities exchanges as may be required. 
 (g) All obligations of the Company under the Plan and this Award Agreement shall be
binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company. 

17. GOVERNING PLAN DOCUMENT. Your Award is subject to all the
provisions of the Plan, the provisions of which are hereby made a part of your Award, 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. Your
Award (and any compensation paid or shares issued under your Award) is subject to recoupment in accordance with The Dodd–Frank Wall Street Reform and Consumer Protection Act and any implementing regulations thereunder, any clawback policy
adopted by the Company and any compensation recovery policy otherwise required by applicable law. No recovery of compensation under such a clawback policy will be an event giving rise to a right to voluntarily terminate employment upon a resignation
for “good reason,” or for a “constructive termination” or any similar term under any plan of or agreement with the Company. 

18. EFFECT ON OTHER EMPLOYEE BENEFIT
PLANS. The value of the Award subject to this Award Agreement shall not be included as compensation, earnings, salaries, or other similar terms used when calculating benefits under any employee benefit plan (other than the Plan)
sponsored by the Company or any Affiliate except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any or all of the employee benefit plans of the Company or any Affiliate. 

19. CHOICE OF LAW. The interpretation, performance and
enforcement of this Award Agreement shall be governed by the law of the State of Delaware without regard to that state’s conflicts of laws rules. 

20. SEVERABILITY. If all or any part of this Award Agreement or the Plan is declared by any court
or governmental authority to be unlawful or invalid, such unlawfulness or invalidity shall not invalidate any portion of this Award Agreement or the Plan not declared to be unlawful or invalid. Any Section of this Award Agreement (or part of such a
Section) so declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid. 

21. OTHER DOCUMENTS. You hereby acknowledge receipt of and the right to receive a
document providing the information required by Rule 428(b)(1) promulgated under the Securities Act, which includes the Plan prospectus. In addition, you acknowledge receipt of the Company’s policy permitting certain individuals to sell
shares only during certain “window” periods and the Company’s insider trading policy, in effect from time to time. 

  
 6. 








 22. AMENDMENT. This Award Agreement may not be modified, amended or
terminated except by an instrument in writing, signed by you and by a duly authorized representative of the Company. Notwithstanding the foregoing, this Award Agreement may be amended solely by the Board by a writing which specifically states that
it is amending this Award Agreement, so long as a copy of such amendment is delivered to you, and provided that, except as otherwise expressly provided in the Plan, no such amendment materially adversely affecting your rights hereunder may be made
without your written consent. Without limiting the foregoing, the Board reserves the right to change, by written notice to you, the provisions of this Award Agreement in any way it may deem necessary or advisable to carry out the purpose of the
Award as a result of any change in applicable laws or regulations or any future law, regulation, ruling, or judicial decision, provided that any such change shall be applicable only to rights relating to that portion of the Award which is then
subject to restrictions as provided herein. 
 23. COMPLIANCE WITH SECTION 409A
OF THE CODE. This Award is intended to comply with the “short-term deferral” rule set forth in Treasury Regulation Section 1.409A-1(b)(4). Notwithstanding the
foregoing, if it is determined that the Award fails to satisfy the requirements of the short-term deferral rule and is otherwise deferred compensation subject to Section 409A, and if you are a “Specified Employee” (within the meaning set
forth in Section 409A(a)(2)(B)(i) of the Code) as of the date of your “separation from service” (within the meaning of Treasury Regulation Section 1.409A-1(h) and without regard to any alternative definition thereunder), then the issuance
of any shares that would otherwise be made upon the date of the separation from service or within the first six (6) months thereafter will not be made on the originally scheduled date(s) and will instead be issued in a lump sum on the earlier of:
(i) the fifth business day following your death, or (ii) the date that is six (6) months and one day after the date of the separation from service, with the balance of the shares issued thereafter in accordance with the original vesting and issuance
schedule set forth above, but if and only if such delay in the issuance of the shares is necessary to avoid the imposition of adverse taxation on you in respect of the shares under Section 409A of the Code. Each installment of shares that vests is
intended to constitute a “separate payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2).
