## Exhibit 10.1

**Exhibit 10.1**![](tm2533427d1_ex10-1img01.jpg)

**ZENAS BIOPHARMA, INC.**

**2026 INDUCEMENT PLAN**

**1.** **DEFINED TERMS** 

<u>Exhibit A</u>, which is incorporated by reference, defines certain terms used in this Plan and includes certain operational rules related to those terms.

**2.** **PURPOSE** 

This Plan has been established to allow the Company to provide an inducement to secure and retain the services of Eligible Individuals (as defined in Section 5) by providing for the grant of Awards to such Eligible Individuals. This Plan is intended to meet the requirements of a plan providing for inducement grants under Rule 5635(c)(4) of the Nasdaq Listing Rules and shall be administered in accordance with such intent.

**3.** **ADMINISTRATION** 

This Plan will be administered by the Administrator. The Administrator has discretionary authority, subject only to the express provisions of this Plan, to administer and interpret this Plan and any Awards; to determine the Eligible Individuals to whom to grant Awards; to determine the exercise price, base value from which appreciation is measured, or purchase price, if any, applicable to any Award, to determine, modify, accelerate or waive the terms and conditions of any Award; to determine the form of settlement of Awards (whether in cash, shares of Stock, other Awards or other property); to prescribe forms, rules and procedures relating to this Plan and Awards; and to otherwise do all things necessary or desirable to carry out the purposes of this Plan or any Award. Determinations of the Administrator made with respect to this Plan or any Award are conclusive and binding upon all persons. Notwithstanding the foregoing or anything in the Plan to the contrary, the grant of Awards must be approved by the Compensation Committee or a majority of the Company's independent directors (as defined in Rule 5605(a)(2) of the Nasdaq Listing Rules) in order to comply with the exemption from the stockholder approval requirement for "inducement grants" provided under Rule 5635(c)(4) of the Nasdaq Listing Rules.

**4.** **SHARE POOL; LIMITS ON AWARDS** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(a)**  **<u>Number of Shares</u>.** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(i)** Subject to adjustment as provided in Section 7(b) of this Plan, the maximum number of shares of Stock that may be delivered in satisfaction of Awards under this Plan is 1,000,000 shares (the "Share Pool").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(ii)** The Share Pool shall not be reduced by (A) any shares of Stock withheld by the Company in payment of the exercise price or purchase price of an Award or in satisfaction of tax withholding requirements with respect to an Award or (B) any shares of Stock underlying any portion of an Award that is settled in cash or that expires, becomes unexercisable, terminates or is forfeited to or repurchased by the Company without the issuance of Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(b) <u>Type of Shares</u>.** Stock delivered by the Company under this Plan may be authorized but unissued Stock, treasury Stock or previously issued Stock acquired by the Company. No fractional shares of Stock will be delivered under this Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(c) <u>Mergers and Acquisitions.</u>** Shares may be issued in connection with Awards granted in respect of converted, replaced or adjusted awards in connection with a merger or acquisition as permitted by Nasdaq Listing Rule 5635(c) or other applicable rule, and any such issuance will not reduce the Share Pool.

**5.** **ELIGIBILITY AND PARTICIPATION** 

Awards may only be granted under the Plan to an individual not previously an employee or director of the Company or any Subsidiary, or to an individual following a bona fide period of non-employment with the Company or any Subsidiary, as an inducement material to the individual's entering into employment with the Company or Subsidiary within the meaning of Rule 5635(c)(4) of the Nasdaq Listing Rules (each such individual, an "Eligible Individual"). In addition, eligibility for Stock Options and SARs is limited to Eligible Individuals who are providing direct services on the date of grant of the Award to the Company or any Subsidiary that would be described in the first sentence of Section 1.409A-1(b)(5)(iii)(E) of the Treasury Regulations.

**6.** **RULES APPLICABLE TO AWARDS** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(a)**  **<u>All Awards</u>.** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(i)** **<u>Award Provisions</u>.** The Administrator will determine the terms and conditions of all Awards, subject to the limitations provided herein. By accepting (or, under such rules as the Administrator may prescribe, being deemed to have accepted) an Award, the Participant will be deemed to have agreed to the terms and conditions of the Award and this Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(ii)** **<u>Term of Plan</u>.** No Awards may be made after ten years from the Date of Adoption, but previously granted Awards may continue beyond that date in accordance with their terms.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(iii)** **<u>Transferability</u>.** Except as the Administrator otherwise expressly provides in accordance with the third sentence of this Section 6(a)(iii), Awards may not be transferred other than by will or by the applicable laws of descent and distribution. During a Participant's lifetime, except as the Administrator otherwise expressly provides in accordance with the third sentence of this Section 6(a)(iii), SARs and Stock Options may be exercised only by the Participant. The Administrator may permit the gratuitous transfer (i.e., transfer not for value) of Awards, subject to applicable securities and other laws and such terms and conditions as the Administrator may determine.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(iv)** **<u>Vesting; Exercisability</u>.** The Administrator will determine the time or times at which an Award vests or becomes exercisable and the terms and conditions on which a Stock Option or SAR remains exercisable. Without limiting the foregoing, the Administrator may at any time accelerate the vesting and/or exercisability of an Award (or any portion thereof), regardless of any adverse or potentially adverse tax or other consequences resulting from such acceleration. Unless the Administrator expressly provides otherwise, however, the following rules will apply if a Participant's Employment ceases:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(A)** Except as provided in (B) and (C) below, immediately upon the cessation of the Participant's Employment, each Stock Option and SAR (or portion thereof) that is then held by the Participant or by the Participant's permitted transferees, if any, will cease to be exercisable and will terminate, and each other Award that is then held by the Participant or by the Participant's permitted transferees, if any, to the extent not then vested, will be forfeited.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(B)** Subject to (C) and (D) below, each vested and unexercised Stock Option and SAR (or portion thereof) held by the Participant or the Participant's permitted transferees, if any, immediately prior to the cessation of the Participant's Employment, to the extent then exercisable, will remain exercisable for the lesser of (i) a period of three months following such cessation of Employment or (ii) the period ending on the latest date on which such Stock Option or SAR could have been exercised without regard to this Section 6(a)(iv), and will thereupon immediately terminate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(C)** Subject to (D) below, each vested and unexercised Stock Option and SAR (or portion thereof) held by a Participant or the Participant's permitted transferees, if any, immediately prior to the cessation of the Participant's Employment due to his or her death or by the Company or a Subsidiary due to his or her Disability, to the extent then exercisable, will remain exercisable for the lesser of (i) the one-year period ending on the first anniversary of such cessation of Employment or (ii) the period ending on the latest date on which such Stock Option or SAR could have been exercised without regard to this Section 6(a)(iv), and will thereupon immediately terminate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(D)** All Awards (whether or not vested or exercisable) held by a Participant or the Participant's permitted transferees, if any, immediately prior to the cessation of the Participant's Employment will immediately terminate upon (i) such cessation of Employment if the termination is for Cause or occurs in circumstances that in the determination of the Administrator would have constituted grounds for the Participant's Employment to be terminated for Cause (in each case, without regard to the lapsing of any required notice or cure periods in connection therewith) or (ii) to the maximum extent permitted under applicable law, the Participant's violation of any non-competition, non-solicitation, no-hire, non-disparagement, confidentiality, invention assignment, or other restrictive covenant in favor of the Company or any of its affiliates by which the Participant is bound.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(v)** **<u>Recovery of Compensation</u>**. The Administrator may provide in any case that any outstanding Award (whether or not vested or exercisable), the proceeds from the exercise or disposition of any Award or Stock acquired under any Award, and any other amounts received in respect of any Award or Stock acquired under any Award will be subject to forfeiture and disgorgement to the Company, with interest and other related earnings, if the Participant to whom the Award was granted is not in compliance with any provision of this Plan or any applicable Award Agreement or any non-competition, non-solicitation, no-hire, non-disparagement, confidentiality, invention assignment or other restrictive covenant by which he or she is bound. Each Award will be subject to any policy of the Company or any Subsidiary that relates to trading on non-public information and permitted transactions with respect to shares of Stock, including limitations on hedging and pledging. In addition, each Award will be subject to any policy of the Company or any of its affiliates that provides for forfeiture, disgorgement, or clawback with respect to incentive compensation that includes Awards under this Plan and will be further subject to forfeiture and disgorgement to the extent required by law or applicable stock exchange listing standards, including, without limitation, Section 10D of the Exchange Act. Each Participant, by accepting or being deemed to have accepted an Award under this Plan, agrees (or will be deemed to have agreed) to the terms of this Section 6(a)(v) and to any clawback, recoupment or similar policy of the Company or any Subsidiary and further agrees (or will be deemed to have further agreed) to cooperate fully with the Administrator, and to cause any and all permitted transferees of the Participant to cooperate fully with the Administrator, to effectuate any forfeiture or disgorgement described in this Section 6(a)(v). Neither the Administrator nor the Company nor any other person, other than the Participant and his or her permitted transferees, if any, will be responsible for any adverse tax or other consequences to a Participant or his or her permitted transferees, if any, that may arise in connection with this Section 6(a)(v).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(vi)** **<u>Taxes</u>.** The grant of an Award and the issuance, delivery, vesting and retention of Stock, cash or other property under an Award are conditioned upon the full satisfaction by the Participant of all tax and other withholding requirements with respect to the Award. The Administrator will prescribe such rules for the withholding of taxes and other amounts with respect to any Award as it deems necessary or appropriate. Without limitation to the foregoing, the Company or, if different, a Subsidiary that is an employer to a Participant who is an employee of such entity will have the authority and the right to deduct or withhold (by any means set forth herein or in an Award Agreement), or require the Participant to remit to it, an amount sufficient to satisfy all U.S. and non-U.S. federal, state and local income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to participation in this Plan and any Award hereunder and legally applicable to the Participant and required by law to be withheld (including, any amount deemed by the Company, in its discretion, to be an appropriate charge to the Participant even if legally applicable to the Company or any affiliate of the Company). The Administrator, in its sole discretion, may hold back shares of Stock from an Award or permit a Participant to tender previously-owned shares of Stock in satisfaction of tax or other withholding requirements (but not in excess of the maximum withholding amount consistent with the Award being subject to equity accounting treatment under the Accounting Rules). Any amounts withheld pursuant to this Section 6(a)(vi) will be treated as though such amounts had been paid directly to the applicable Participant. In addition, the Company may, to the extent permitted by law, deduct any such tax and other withholding amounts from any payment of any kind otherwise due to a Participant from the Company or any of its affiliates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(vii)** **<u>Dividend Equivalents</u>.** The Administrator may provide for the payment of amounts (on terms and subject to such restrictions and conditions established by the Administrator) in lieu of cash dividends or other cash distributions with respect to Stock subject to an Award whether or not the holder of such Award is otherwise entitled to share in the actual dividend or distribution in respect of such Award; *provided, however*, that, except as contemplated by Section 7 of this Plan, (A) dividends or dividend equivalents relating to an Award that, at the dividend payment date, remains subject to a risk of forfeiture (whether service-based or performance-based) shall be subject to the same risk of forfeiture as applies to the underlying Award and (B) no dividends or dividend equivalents shall be payable with respect to Stock Options or SARs. Any entitlement to dividend equivalents or similar entitlements will be established and administered either consistent with an exemption from, or in compliance with, the applicable requirements of Section 409A.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(viii)** **<u>Rights Limited</u>.** Nothing in this Plan or any Award will be construed as giving any person the right to be granted an Award or to continued Employment, or any rights as a stockholder except as to shares of Stock actually delivered under this Plan. The loss of existing or potential profit in any Award will not constitute an element of damages in the event of a termination of a Participant's Employment for any reason, even if the termination is in violation of an obligation of the Company or any Subsidiary to the Participant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(ix)** **<u>Section 409A</u>.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(A)** Without limiting the generality of Section 11(b) of this Plan, each Award will contain such terms as the Administrator determines and will be construed and administered, such that the Award either qualifies for an exemption from the requirements of Section 409A or satisfies such requirements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(B)** Notwithstanding anything to the contrary in this Plan or any Award Agreement, the Administrator may unilaterally amend, modify or terminate this Plan or any outstanding Award, including, without limitation, changing the form of the Award, if the Administrator determines that such amendment, modification or termination is necessary or desirable to avoid the imposition of any additional tax, interest or penalty under Section 409A.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(C)** If a Participant is determined on the date of the Participant's termination of Employment to be a "specified employee" within the meaning of that term under Section 409A(a)(2)(B) of the Code, then, with regard to any payment that is considered nonqualified deferred compensation under Section 409A, to the extent applicable, payable on account of a "separation from service", such payment will be made or provided on the date that is the earlier of (i) the first business day following the expiration of the six-month period measured from the date of such "separation from service" and (ii) the date of the Participant's death (the "**Delay Period**"). Upon the expiration of the Delay Period, all payments delayed pursuant to this Section 6(a)(ix)(C) (whether they would have otherwise been payable in a single lump sum or in installments in the absence of such delay) will be paid, without interest, on the first business day following the expiration of the Delay Period in a lump sum and any remaining payments due under the Award will be paid in accordance with the normal payment dates specified for them in the applicable Award Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(D)** For purposes of Section 409A, each payment made under this Plan or any Award will be treated as a separate payment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(E)** With regard to any payment considered to be nonqualified deferred compensation under Section 409A, to the extent applicable, that is payable upon a change in control of the Company or other similar event, to the extent required to avoid the imposition of any additional tax, interest or penalty under Section 409A, no amount will be payable unless such change in control constitutes a "change in control event" within the meaning of Section 1.409A-3(i)(5) of the Treasury Regulations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(b)**  **<u>Stock Options and SARs</u>.** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(i)** **<u>Time and Manner of Exercise</u>.** Unless the Administrator expressly provides otherwise, no Stock Option or SAR will be deemed to have been exercised until the Administrator receives a notice of exercise in a form acceptable to the Administrator that is signed by the appropriate person and accompanied by any payment required under the Award. The Administrator may limit or restrict the exercisability of any Stock Option or SAR in its discretion, including in connection with any Covered Transaction. Any attempt to exercise a Stock Option or SAR by any person other than the Participant will not be given effect unless the Administrator has received such evidence as it may require that the person exercising the Award has the right to do so.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(ii)** **<u>Exercise Price</u>.** The exercise price (or the base value from which appreciation is to be measured) per share of each Award requiring exercise must be no less than 100% of the Fair Market Value of a share of Stock, determined as of the date of grant of the Award, or such higher amount as the Administrator may determine in connection with the grant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(iii)** **<u>Payment of Exercise Price</u>.** Where the exercise of an Award (or portion thereof) is to be accompanied by a payment, payment of the exercise price must be made by cash or check acceptable to the Administrator or, if so permitted by the Administrator and if legally permissible, (A) through the delivery of previously acquired unrestricted shares of Stock, or the withholding of unrestricted shares of Stock otherwise deliverable upon exercise, in either case, that have a Fair Market Value equal to the exercise price; (B) through a broker-assisted cashless exercise program acceptable to the Administrator; (C) by other means acceptable to the Administrator; or (D) by any combination of the foregoing permissible forms of payment. The delivery of previously acquired shares in payment of the exercise price under clause (A) above may be accomplished either by actual delivery or by constructive delivery through attestation of ownership, subject to such rules as the Administrator may prescribe.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(iv)** **<u>Maximum Term</u>.** The maximum term of Stock Options and SARs must not exceed 10 years from the date of grant.

**7.** **EFFECT OF CERTAIN TRANSACTIONS** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(a) <u>Mergers, *etc*</u>*.*** Except as otherwise expressly provided in an Award Agreement or other agreement or by the Administrator, the following provisions will apply in the event of a Covered Transaction:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(i)** **<u>Assumption or Substitution</u>.** If the Covered Transaction is one in which there is an acquiring or surviving entity, the Administrator may provide for (A) the assumption or continuation of some or all outstanding Awards or any portion thereof or (B) the grant of new awards in substitution therefor by the acquiror or survivor or an affiliate of the acquiror or survivor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(ii)** **<u>Cash-Out of Awards</u>.** Subject to Section 7(a)(v) of this Plan, the Administrator may provide for payment (a "**cash-out**"), with respect to some or all Awards or any portion thereof (including only the vested portion thereof, with the unvested portion terminating without payment due as provided in Section 7(a)(iv) of this Plan), equal in the case of each applicable Award or portion thereof to the excess, if any, of (A) the Fair Market Value of one share of Stock multiplied by the number of shares of Stock subject to the Award or such portion, minus (B) the aggregate exercise or purchase price, if any, of such Award or such portion thereof (or, in the case of a SAR, the aggregate base value above which appreciation is measured), in each case, on such payment and other terms and subject to such conditions (which need not be the same as the terms and conditions applicable to holders of Stock generally), as the Administrator determines, including that any amounts paid in respect of such Award in connection with the Covered Transaction be placed in escrow or otherwise made subject to such restrictions as the Administrator deems appropriate. For the avoidance of doubt, if the per share exercise or purchase price (or base value) of an Award or portion thereof is equal to or greater than the Fair Market Value of one share of Stock, such Award or portion may be cancelled with no payment due hereunder or otherwise in respect thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(iii)** **<u>Acceleration of Certain Awards</u>.** Subject to Section 7(a)(v) of this Plan, the Administrator may provide that any Award requiring exercise will become exercisable, in full or in part, and/or that the delivery of any shares of Stock remaining deliverable under any outstanding Award of Stock Units (including Restricted Stock Units and Performance Awards to the extent consisting of Stock Units) will be accelerated, in full or in part, in each case on a basis that gives the holder of the Award a reasonable opportunity, as determined by the Administrator, following the exercise of the Award or the delivery of the shares, as the case may be, to participate as a stockholder in the Covered Transaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(iv)** **<u>Termination of Awards upon Consummation of Covered Transaction</u>.** Except as the Administrator may otherwise determine, each Award will automatically terminate immediately upon the consummation of the Covered Transaction, other than (A) any Award that is assumed or continued pursuant to Section 7(a)(i)(A) of this Plan and (B) any Award that by its terms, or as a result of action taken by the Administrator, continues following the Covered Transaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(v)** **<u>Additional Limitations</u>.** Any share of Stock and any cash or other property or other award delivered pursuant to Section 7(a)(i), Section 7(a)(ii) or Section 7(a)(iii) of this Plan with respect to an Award may, in the discretion of the Administrator, contain such restrictions, if any, as the Administrator deems appropriate, including to reflect any performance or other vesting conditions to which the Award was subject and that did not lapse (and were not satisfied) in connection with the Covered Transaction. For purposes of the immediately preceding sentence, a cash-out under Section 7(a)(ii) of this Plan or an acceleration under Section 7(a)(iii) of this Plan will not, in and of itself, be treated as the lapsing (or satisfaction) of a performance or other vesting condition.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(vi)** **<u>Uniform Treatment</u>.** For the avoidance of doubt, the Administrator need not treat Participants or Awards (or portions thereof) in a uniform manner, and may treat different Participants and/or Awards differently, in connection with a Covered Transaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(b)**  **<u>Changes in and Distributions with Respect to Stock</u>.** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(i)** **<u>Basic Adjustment Provisions</u>.** In the event of a stock dividend, stock split or combination of shares (including a reverse stock split), recapitalization or other change in the Company's capital structure that constitutes an equity restructuring within the meaning of the Accounting Rules, the Administrator shall make appropriate adjustments to the Share Pool, and shall make appropriate adjustments to the number and kind of shares of stock or securities underlying Awards then outstanding or subsequently granted, any exercise or purchase prices (or base values) relating to Awards and any other provision of Awards affected by such change.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(ii)** **<u>Certain Other Adjustments</u>.** The Administrator may also make adjustments of the type described in Section 7(b)(i) of this Plan to take into account distributions to stockholders other than those provided for in Sections 7(a) and 7(b)(1) of this Plan, or any other event, if the Administrator determines that adjustments are appropriate to avoid distortion in the operation of this Plan or any Award.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(iii)** **<u>Continuing Application of Plan Terms</u>.** References in this Plan to shares of Stock will be construed to include any stock or securities resulting from an adjustment pursuant to this Section 7.

**8.** **LEGAL CONDITIONS ON DELIVERY OF STOCK** 

An Award will not be effective unless such Award is in compliance with all applicable U.S. federal and state securities laws, any non-U.S. securities and exchange control laws, the Nasdaq Listing Rules, and any other laws, the rules and regulations of any governmental body and the requirements of any stock exchange or automated quotation system upon which the shares of Stock may then be listed or quoted, as they are in effect on the date of grant of the Award and also on the date of exercise or other issuance. The Company will not be obligated to deliver any shares of Stock pursuant to this Plan or to remove any restriction from shares of Stock previously delivered under this Plan until: (a) the Company is satisfied, in its sole discretion, that all legal matters (as referenced above) in connection with the issuance and delivery of such shares have been addressed and resolved; (b) if the outstanding Stock is at the time of delivery listed on any stock exchange or national market system, the shares to be delivered have been listed or authorized to be listed on such exchange or system upon official notice of issuance; and (c) all conditions of the Award have been satisfied or waived. The Company may require, as a condition to the exercise of an Award or the delivery of shares of Stock under an Award, such representations or agreements as counsel for the Company may consider appropriate to avoid violation of the U.S. Securities Act of 1933, as amended, the Nasdaq Listing Rules, or any applicable state or non-U.S. securities law. Any Stock delivered under this Plan will be evidenced in such manner as the Administrator determines appropriate, including book-entry registration or delivery of stock certificates. In the event that the Administrator determines that stock certificates will be issued in connection with Stock issued under this Plan, the Administrator may require that such certificates bear an appropriate legend reflecting any restriction on transfer applicable to such Stock, and the Company may hold the certificates pending the lapse of the applicable restrictions.

**9.** **AMENDMENT AND TERMINATION** 

The Administrator may at any time or times amend this Plan or any outstanding Award for any purpose which may at the time be permitted by applicable law, and may at any time terminate this Plan as to any future grants of Awards; *provided, however*, that except as otherwise expressly provided in this Plan or the applicable Award, the Administrator may not, without the Participant's consent, alter the terms of an Award so as to affect materially and adversely the Participant's rights under the Award, unless the Administrator expressly reserved the right to do so in this Plan or at the time the applicable Award was granted. Any amendments to this Plan will be conditioned upon stockholder approval only to the extent, if any, such approval is required by applicable law (including the Code) or stock exchange requirements, as determined by the Administrator. For the avoidance of doubt, without limiting the Administrator's rights hereunder, no adjustment to any Award pursuant to the terms of Section 7 or Section 12 of this Plan will be treated as an amendment requiring a Participant's consent.

**10.** **OTHER COMPENSATION ARRANGEMENTS** 

The existence of this Plan or the grant of any Award will not affect the right of the Company or any Subsidiary to grant any person bonuses or other compensation in addition to Awards under this Plan.

**11.** **MISCELLANEOUS** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(a) <u>Waiver of Jury Trial</u>.** By accepting or being deemed to have accepted an Award under this Plan, each Participant waives (or will be deemed to have waived), to the maximum extent permitted under applicable law, any right to a trial by jury in any action, proceeding or counterclaim concerning any rights under this Plan or any Award, or under any amendment, waiver, consent, instrument, document or other agreement delivered or which in the future may be delivered in connection therewith, and agrees (or will be deemed to have agreed) that any such action, proceedings or counterclaim will be tried before a court and not before a jury. By accepting (or being deemed to have accepted) an Award under this Plan, each Participant certifies that no officer, representative, or attorney of the Company has represented, expressly or otherwise, that the Company would not, in the event of any action, proceeding or counterclaim, seek to enforce the foregoing waivers. Notwithstanding anything to the contrary in this Plan, nothing herein is to be construed as limiting the ability of the Company and a Participant to agree to submit any dispute arising under the terms of this Plan or any Award to binding arbitration or as limiting the ability of the Company to require any individual to agree to submit such disputes to binding arbitration as a condition of receiving an Award hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(b) <u>Limitation of Liability</u>.** Notwithstanding anything to the contrary in this Plan or any Award, neither the Company, nor any Subsidiary, nor the Administrator, nor any person acting on behalf of the Company, any Subsidiary, or the Administrator, will be liable to any Participant, to any permitted transferee, to the estate or beneficiary of any Participant or any permitted transferee, or to any other person by reason of any acceleration of income, any additional tax, or any penalty, interest or other liability asserted by reason of the failure of an Award to satisfy the requirements of Section 409A or by reason of Section 4999 of the Code, or otherwise asserted with respect to any Award.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(c) <u>Unfunded Plan</u>.** The Company's obligations under this Plan are unfunded, and no Participant will have any right to specific assets of the Company in respect of any Award. Participants will be general unsecured creditors of the Company with respect to any amounts due or payable under this Plan.

**12.** **RULES FOR PARTICIPANTS SUBJECT TO NON-U.S. LAWS** 

To comply with laws in countries outside of the U.S. in which the Company and its Subsidiaries operate or in which Participants work or reside, the Administrator, in its sole discretion, shall have the power and authority to (i) determine which Participants outside the U.S. will be eligible to participate in the Plan; (ii) modify the terms and conditions of any Award granted to Participants outside the U.S.; (iii) establish, adopt, or revise any rules and regulations as it may deem necessary or advisable to administer this Plan for Participants based outside of the U.S. and/or subject to the laws of countries other than the U.S., including by establishing one or more sub-plans, supplements or appendices under this Plan or any Award Agreement for the purpose of complying or facilitating compliance with non-U.S. laws or taking advantage of tax favorable treatment or for any other legal or administrative reason determined by the Administrator; and (iv) take any action, before or after an Award is granted, that it deems advisable to obtain approval or to facilitate compliance with any necessary local governmental regulatory exemptions or approvals. Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules, procedures and sub-plans with provisions that limit or modify rights on eligibility to receive an Award under the Plan or on death, disability, retirement or other termination of Employment, available methods of exercise or settlement of an Award, payment of income, social insurance contributions and payroll taxes, the shifting of employer tax or social insurance contribution liability to the Participant, the withholding procedures and handling of any stock certificates or other indicia of ownership. Any such sub-plan, supplement or appendix may contain, in each case, (i) such limitations on the Administrator's discretion under this Plan and (ii) such additional or different terms and conditions, as the Administrator deems necessary or desirable, and will be deemed to be part of this Plan but will apply only to Participants within the group to which the sub-plan, supplement or appendix applies (as determined by the Administrator); *provided, however*, that no sub-plan, supplement or appendix, rule or regulation established pursuant to this provision shall increase the Share Pool contained in Section 4 of the Plan or cause a violation of any U.S. law.

**13.** **GOVERNING LAW** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(a) <u>Certain Requirements of Corporate Law</u>.** Awards and shares of Stock will be granted, issued and administered consistent with the requirements of applicable Delaware law relating to the issuance of stock and the consideration to be received therefor, and with the applicable requirements of the stock exchanges or other trading systems on which the Stock is listed or entered for trading, in each case, as determined by the Administrator.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(b) <u>Other Matters</u>.** Except as otherwise provided by the express terms of an Award Agreement, under a sub-plan described in Section 12 of this Plan or as provided in Section 13(a) of this Plan, the domestic substantive laws of the State of Delaware govern the provisions of this Plan and of Awards under this Plan and all claims or disputes arising out of or based upon this Plan or any Award under this Plan or relating to the subject matter hereof or thereof without giving effect to any choice or conflict of laws provision or rule that would cause the application of the domestic substantive laws of any other jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(c) <u>Jurisdiction</u>.** Subject to Section 11(a) of this Plan and except as otherwise provided by the express terms of an Award Agreement, by accepting (or being deemed to have accepted) an Award, each Participant agrees or will be deemed to have agreed to (i) submit irrevocably and unconditionally to the jurisdiction of the federal and state courts located within the geographic boundaries of the United States District Court for the District of Massachusetts for the purpose of any suit, action or other proceeding arising out of or based upon this Plan or any Award; (ii) not commence any suit, action or other proceeding arising out of or based upon this Plan or any Award, except in the federal and state courts located within the geographic boundaries of the United States District Court for the District of Massachusetts; and (iii) waive, and not assert, by way of motion as a defense or otherwise, in any such suit, action or proceeding, any claim that he or she is not subject personally to the jurisdiction of the above-named courts that his or her property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Plan or any Award or the subject matter thereof may not be enforced in or by such court.

**ZENAS BIOPHARMA, INC.<br> 2026 INDUCEMENT PLAN**

**<u>Non-Statutory Stock Option Agreement</u>**

This agreement (this "**Agreement**") evidences a stock option (the "**Stock Option**") granted by Zenas BioPharma, Inc., a Delaware corporation (the "**Company**"), to the individual named above (the "**Participant**"), pursuant to and subject to the terms of the Zenas BioPharma, Inc. 2026 Inducement Plan (as from time to time amended and in effect, the "**Plan**"). Except as otherwise defined herein, all capitalized terms used herein have the same meaning as in the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. <u>Grant of Stock Option</u>. On the date of grant set forth above (the "**Date of Grant**"), the Company granted to the Participant the Stock Option to purchase, pursuant to and subject to the terms and conditions set forth in this Agreement and in the Plan, up to the number of shares of Stock set forth above (the "**Shares**"), with an exercise price per Share as set forth above, in each case subject to adjustment pursuant to Section 7 of the Plan in respect of transactions occurring after the date hereof.

The Stock Option evidenced by this Agreement is a non-statutory option (that is, an option that is not intended to qualify as an incentive stock option) and is granted to the Participant in connection with the Participant's Employment as an employee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. <u>Vesting</u>. The term "**vest**" as used herein with respect to the Stock Option or any portion thereof means to become exercisable and the term "**vested**" as used herein with respect to the Stock Option (or any portion thereof) means that the Stock Option (or portion thereof) is then exercisable. Unless earlier terminated, forfeited, relinquished or expired, the Stock Option will vest as follows: [INSERT VESTING SCHEDULE].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. <u>Exercise of the Stock Option</u>. No portion of the Stock Option may be exercised until such portion vests. Each election to exercise any vested portion of the Stock Option will be subject to the terms and conditions of this Agreement and the Plan and must be in written or electronic form acceptable to the Administrator, signed (including by electronic signature) by the Participant or, if at the relevant time the Stock Option has passed to the estate or beneficiary of the Participant or a permitted transferee, by such estate or beneficiary or permitted transferee. Each such written or electronic exercise election must be received by the Company at its principal office or at such other place or by such other party as the Administrator may prescribe and must be accompanied by payment in full of the exercise price by cash or check, through a broker-assisted exercise program acceptable to the Administrator, or as otherwise provided in the Plan. Subject to earlier termination as set forth herein or in the Plan (including Section 6(a)(iv) of the Plan), the latest date on which the Stock Option or any portion thereof may be exercised is the tenth (10<sup>th</sup>) anniversary of the Date of Grant and, if not exercised on or prior to such date, the Stock Option or any remaining portion thereof will thereupon immediately terminate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. <u>Cessation of Employment</u>. Except as (a) the Administrator may determine in its discretion or (b) expressly provided for in an employment agreement between the Participant and the Company that is in effect at the time of such termination, if the Participant's Employment ceases for any reason, the Stock Option, to the extent not then vested, will be immediately forfeited for no consideration, and any vested portion of the Stock Option that is then outstanding will remain exercisable for the period, if any, described in Section 6(a)(iv) of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. <u>Forfeiture; Recovery of Compensation</u>. By accepting, or being deemed to have accepted, the Stock Option, the Participant expressly acknowledges and agrees that his or her rights, and those of any permitted transferee, with respect to the Stock Option, including the right to any Shares acquired under the Stock Option and any amounts received in respect thereof, are subject to Section 6(a)(v) of the Plan (including any successor provision). The Participant further agrees to be bound by the terms of any applicable clawback or recoupment policy of the Company. Nothing in the preceding sentence will be construed as limiting the general application of Section 9 of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. <u>Nontransferability</u>. The Stock Option may not be transferred except as expressly permitted under Section 6(a)(iii) of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. <u>Taxes</u>. The Participant expressly acknowledges and agrees that the Participant's rights hereunder, including the right to be issued Shares upon exercise of the Stock Option, are subject to the Participant promptly paying to the Company in cash or by check (or by such other means as may be acceptable to the Administrator in its discretion) all taxes required to be withheld. No Shares will be transferred pursuant to the exercise of this Stock Option unless and until the person exercising the Stock Option has remitted to the Company an amount sufficient to satisfy any federal, state, or local withholding tax requirements, or has made other arrangements reasonably satisfactory to the Company with respect to such taxes. The Participant authorizes the Company and any Subsidiary to withhold such amounts from any amounts otherwise owed to the Participant, but nothing in this sentence will be construed as relieving the Participant from any liability for satisfying his or her obligation under the preceding provisions of this Section.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. <u>Section 280G</u>. If any payment or benefit that the Participant may receive in respect of the Stock Option (the "<u>Payment</u>"), would (i) constitute a "parachute payment" within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the "<u>Excise Tax</u>"), then such Payment shall be reduced to the Reduced Amount. The "<u>Reduced Amount</u>" shall be either (A) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (B) the largest portion, up to and including the total amount, of the Payment, whichever of the amounts determined under (A) and (B), after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in the Participant's receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. <u>Provisions of the Plan</u>. This Agreement is subject in its entirety to the provisions of the Plan, which are incorporated herein by reference. A copy of the Plan as in effect on the Date of Grant has been made available to the Participant. By accepting, or being deemed to have accepted, the Stock Option, the Participant agrees to be bound by the terms of the Plan and this Agreement. In the event of any conflict between the terms of this Agreement and the Plan, the terms of the Plan will control.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. <u>No Guarantee of Continued Service</u>. The Participant acknowledges and agrees that nothing in this Agreement constitutes an express or implied promise of continued employment or other engagement with the Company or any Subsidiary for any period of time or shall interfere in any way with the right of the Company or any Subsidiary to terminate the Participant's relationship as an employee or other service provider at any time, with or without Cause.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. <u>Acknowledgements</u>. The Participant acknowledges and agrees that (i) this Agreement may be executed in two or more counterparts, each of which will be an original and all of which together will constitute one and the same instrument, (ii) this Agreement may be executed and exchanged using facsimile, portable document format (PDF) or electronic signature, which, in each case, will constitute an original signature for all purposes hereunder, and (iii) such signature by the Company will be binding against the Company and will create a legally binding agreement when this Agreement is countersigned by the Participant.

**ZENAS BIOPHARMA, INC.<br> 2026 INDUCEMENT PLAN**

**<u>Restricted Stock Unit Agreement</u>**

This agreement (this "**Agreement**") evidences a grant (the "**Award**") of Restricted Stock Units ("**RSUs**") by Zenas BioPharma, Inc., a Delaware corporation (the "**Company**"), to the individual named above (the "**Participant**"), pursuant to and subject to the terms of the Zenas BioPharma, Inc. 2026 Inducement Plan (as from time to time amended and in effect, the "**Plan**"). Except as otherwise defined herein, all capitalized terms used herein have the same meaning as in the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. <u>Grant of RSUs</u>. The Company grants to the Participant on the date set forth above (the "**Date of Grant**") the number of Restricted Stock Units ("**RSUs**") set forth above, giving the Participant the conditional right to receive, without payment and pursuant to and subject to the terms and conditions set forth in this Agreement and in the Plan, one share of Stock (a "**Share**") with respect to each RSU subject to this Award, subject to adjustment pursuant to Section 7 of the Plan in respect of transactions occurring after the date hereof.

The RSUs are granted to the Participant in connection with the Participant's Employment as an employee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. <u>Vesting</u>. Unless earlier terminated, forfeited, relinquished or expired, the RSUs will vest as follows: [INSERT VESTING TERMS].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. <u>Cessation of Employment</u>. Except as (a) the Administrator may determine in its discretion or (b) expressly provided for in an employment agreement between the Participant and the Company that is in effect at the time of the Participant's termination of Employment, if the Participant's Employment ceases for any reason, the RSUs, to the extent not then vested, will be immediately forfeited for no consideration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. <u>Delivery of Shares</u>. Subject to Section 5 below, the Company shall, as soon as practicable upon the vesting of any RSUs (but in no event later than thirty (30) days following the date on which such RSUs vest), effect delivery of the Shares with respect to such vested RSUs to the Participant (or, in the event of the Participant's death, to the person to whom the Award has passed by will or the laws of descent and distribution). No Shares will be issued pursuant to this Award unless and until all legal requirements applicable to the issuance or transfer of such Shares have been complied with to the satisfaction of the Administrator.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. <u>Forfeiture; Recovery of Compensation</u>. The Administrator may cancel, rescind, withhold or otherwise limit or restrict this Award at any time if the Participant is not in compliance with all applicable provisions of this Agreement and the Plan. By accepting, or being deemed to have accepted, the RSUs, the Participant expressly acknowledges and agrees that his or her rights, and those of any permitted transferee, with respect to the RSUs, including the right to any Shares acquired in respect of the RSUs and any amounts received in respect thereof, are subject to Section 6(a)(v) of the Plan (including any successor provision). The Participant further agrees to be bound by the terms of any applicable clawback or recoupment policy of the Company, including the Company's Policy for Recoupment of Incentive Compensation Policy. Nothing in the preceding sentence will be construed as limiting the general application of Section 10 of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. <u>Nontransferability</u>. The RSUs may not be transferred except as expressly permitted under Section 6(a)(iii) of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. <u>Taxes</u>. The Participant expressly acknowledges and agrees that the Participant's rights hereunder, including the right to be issued Shares upon settlement of the Award, are subject to the Participant promptly paying to the Company in cash or by check (or by such other means as may be acceptable to the Administrator) all taxes and other amounts required to be withheld. No Shares will be issued in respect of the Award unless and until the Participant has remitted to the Company an amount in cash sufficient to satisfy any withholding requirements, or has made other arrangements satisfactory to the Company with respect to such amounts. Unless otherwise determined by the Compensation Committee, the Company shall automatically satisfy any tax withholding obligations by causing such number of Shares to be sold in accordance with a sell-to-cover arrangement. The Participant authorizes the Company and its subsidiaries to withhold any amounts due in respect of any required withholdings by withholding from the Shares otherwise deliverable in connection with the RSUs, by causing such Shares to be sold in accordance with a sell-to-cover arrangement and/or by withholding from any amounts otherwise owed to the Participant. The Participant shall bear all costs associated with the sale of Shares under any sell-to-cover arrangement. Nothing in this Section 7, however, shall be construed as relieving the Participant of any liability for satisfying his or her tax obligations relating to the Award. If the Company does not have any withholding obligations for any applicable taxes relating to the Award, the Participant shall be solely responsible for satisfying and paying all taxes arising from or due in connection with the Award, its vesting and/or settlement and any disposition of any Shares acquired upon the vesting of the Award.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. <u>Nature of Grant</u>. By accepting the Award, the Participant acknowledges, understands and agrees that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the Plan is established voluntarily by the Company, is wholly discretionary in nature and may be modified, amended, suspended, or terminated by the Company at any time, to the extent permitted by the Plan;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the Plan is operated and the Award is granted solely by the Company and only the Company is a party to this Agreement; accordingly, any rights the Participant may have under this Agreement may be raised only against the Company but not any Subsidiary (including, but not limited to, the Subsidiary that employs the Participant (the "**Service Recipient**"));

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) no Subsidiary of the Company (including, but not limited to, the Service Recipient) has any obligation to make any payment of any kind to the Participant under this Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the grant of the Award is exceptional, voluntary and occasional and does not create any contractual or other right to receive future grants of restricted stock units, or benefits in lieu of restricted stock units, even if restricted stock units have been granted in the past;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) all decisions with respect to future grants of restricted stock units or other grants, if any, will be at the sole discretion of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) the Award and the Participant's participation in the Plan shall not create a right of Employment with the Company or any Subsidiary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) the Award and the Participant's participation in the Plan shall not be interpreted as forming or amending an employment or service contract with the Company or the Service Recipient, and shall not interfere with the ability of the Company, the Service Recipient or any Subsidiary, as applicable, to terminate the Participant's Employment (if any);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) the Participant is voluntarily participating in the Plan;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Award and any Shares acquired under the Plan, and the income from and value of the same, are not intended to replace any pension rights or compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) the Award and any Shares acquired under the Plan, and the income from and value of the same, are not part of normal or expected compensation for any purposes, including but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards, holiday pay, pension or retirement or welfare benefits or similar payments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) the future value of the Shares underlying the Award is unknown, indeterminable, and cannot be predicted with certainty;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) no claim or entitlement to compensation or damages shall arise from (i) forfeiture of any portion of the Award resulting from the Participant's termination of Employment (for any reason whatsoever and regardless of whether or not later found to be invalid or in breach of applicable laws in the jurisdiction where the Participant is providing service or the terms of the Participant's employment or other service agreement, if any), or (ii) the application of any clawback or recoupment policy adopted by the Company or imposed by applicable laws;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m) unless otherwise agreed with the Company in writing, the Award and the Shares subject to the Award, and the income from and value of the same, are not granted as consideration for, or in connection with, the service the Participant may provide as a director of a Subsidiary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(n) unless otherwise provided in the Plan or by the Company in its discretion, the Award and the benefits evidenced by this Agreement do not create any entitlement to have the Award or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the Shares; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(o) neither the Company, the Service Recipient nor any Subsidiary shall be liable for any foreign exchange rate fluctuation between the Participant's local currency and the U.S. dollar that may affect the value of the Shares or of any amounts due to the Participant pursuant to the settlement of the Award or the subsequent sale of any Shares acquired upon settlement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. <u>Section 280G</u>.

**ZENAS BIOPHARMA, INC.<br> 2026 INDUCEMENT PLAN**

**<u>Global Non-Statutory Stock Option Agreement</u>**

This agreement, including the additional terms and conditions for certain countries, set forth in the appendix attached hereto (the "**Appendix**" and, together with this Global Non-Statutory Stock Option Agreement, the "**Agreement**") evidences a stock option (the "**Stock Option**") granted by Zenas BioPharma, Inc., a Delaware corporation (the "**Company**"), to the individual named above (the "**Participant**"), pursuant to and subject to the terms of the Zenas BioPharma, Inc. 2026 Inducement Plan (as from time to time amended and in effect, the "**Plan**"). Except as otherwise defined herein, all capitalized terms used herein have the same meaning as in the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. <u>Grant of Stock Option</u>. On the date of grant set forth above (the "**Date of Grant**"), the Company granted to the Participant the Stock Option to purchase, pursuant to and subject to the terms and conditions set forth in this Agreement and in the Plan, up to the number of shares of Stock set forth above (the "**Shares**"), with an exercise price per Share as set forth above, in each case subject to adjustment pursuant to Section 7 of the Plan in respect of transactions occurring after the date hereof.

The Stock Option evidenced by this Agreement is a non-statutory option (that is, an option that is not intended to qualify as an incentive stock option) and is granted to the Participant in connection with the Participant's Employment as an employee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. <u>Vesting</u>. The term "**vest**" as used herein with respect to the Stock Option or any portion thereof means to become exercisable and the term "**vested**" as used herein with respect to the Stock Option (or any portion thereof) means that the Stock Option (or portion thereof) is then exercisable. Unless earlier terminated, forfeited, relinquished or expired, the Stock Option will vest as follows: [INSERT VESTING SCHEDULE].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. <u>Exercise of the Stock Option</u>. No portion of the Stock Option may be exercised until such portion vests. Each election to exercise any vested portion of the Stock Option will be subject to the terms and conditions of this Agreement and the Plan and must be in written or electronic form acceptable to the Administrator, signed (including by electronic signature) by the Participant or, if at the relevant time the Stock Option has passed to the estate or beneficiary of the Participant or a permitted transferee, by such estate or beneficiary or permitted transferee. Each such written or electronic exercise election must be received by the Company at its principal office or at such other place or by such other party as the Administrator may prescribe and must be accompanied by payment in full of the exercise price by cash or check, through a broker-assisted exercise program acceptable to the Administrator, or as otherwise provided in the Plan and provided that such method of payment is in compliance with applicable laws. Subject to earlier termination as set forth herein or in the Plan (including Section 6(a)(iv) of the Plan), the latest date on which the Stock Option or any portion thereof may be exercised is the tenth (10<sup>th</sup>) anniversary of the Date of Grant and, if not exercised on or prior to such date, the Stock Option or any remaining portion thereof will thereupon immediately terminate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. <u>Cessation of Employment</u>. Except as (a) the Administrator may determine in its discretion or (b) expressly provided for in an employment agreement between the Participant and the Company that is in effect at the time of such termination, if the Participant's Employment ceases for any reason, the Stock Option, to the extent not then vested, will be immediately forfeited for no consideration, and any vested portion of the Stock Option that is then outstanding will remain exercisable for the period, if any, described in Section 6(a)(iv) of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. <u>Forfeiture; Recovery of Compensation</u>. By accepting, or being deemed to have accepted, the Stock Option, the Participant expressly acknowledges and agrees that his or her rights, and those of any permitted transferee, with respect to the Stock Option, including the right to any Shares acquired under the Stock Option and any amounts received in respect thereof, are subject to Section 6(a)(v) of the Plan (including any successor provision). The Participant further agrees to be bound by the terms of any applicable clawback or recoupment policy of the Company. Nothing in the preceding sentence will be construed as limiting the general application of Section 11 of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. <u>Nontransferability</u>. The Stock Option may not be transferred except as expressly permitted under Section 6(a)(iii) of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. <u>Responsibility for Taxes</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Participant acknowledges that, regardless of any action taken by the Company or, if different, the Subsidiary which employs the Participant or to which the Participant otherwise renders service (the "**Service Recipient**"), the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to the Participant's participation in the Plan and legally applicable or deemed applicable to the Participant ("**Tax-Related Items**") is and remains the Participant's responsibility and may exceed the amount (if any) actually withheld by the Company or the Service Recipient. The Participant further acknowledges that the Company and/or the Service Recipient (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Stock Option, including, but not limited to, the grant, vesting or exercise of the Stock Option, or the subsequent sale of Shares acquired pursuant to such exercise; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Stock Option to reduce or eliminate the Participant's liability for Tax-Related Items or achieve any particular tax result. Further, if the Participant is subject to Tax-Related Items in more than one jurisdiction, the Participant acknowledges that the Company and/or the Service Recipient (or former Service Recipient, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In connection with any relevant taxable or tax withholding event, as applicable, the Participant agrees to make adequate arrangements satisfactory to the Company and/or the Service Recipient to satisfy all Tax-Related Items. In this regard, the Participant hereby authorizes the Company and/or the Service Recipient, or their respective agents, at their discretion, to satisfy any applicable withholding obligations or rights for Tax-Related Items (as applicable) by one or a combination of the following methods:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) requiring the Participant to make a payment in a form acceptable to the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) withholding from the Participant's salary, wages, or any other amounts payable to the Participant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) withholding from proceeds of the sale of Shares otherwise issuable upon exercise of the Stock Option either through a voluntary sale or through a mandatory sale arranged by the Company (on the Participant's behalf pursuant to this authorization without further consent); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) any other method of withholding determined by the Company and to the extent required by applicable laws or the Plan, approved by the Compensation Committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Company may withhold or account for Tax-Related Items by considering statutory or other withholding rates, including up to the maximum rates applicable in the Participant's jurisdiction(s). If the application of the withholding rate leads to over-withholding, the Participant may receive a refund of any over-withheld amount in cash from the Company or the Service Recipient (with no entitlement to the equivalent in Shares) or, if not refunded, the Participant may be able to seek a refund from the local tax authorities. If the application of the withholding rate leads to under-withholding, the Participant may be required to pay any additional Tax-Related Items directly to the applicable tax authority or to the Company and/or the Service Recipient. If the obligations for Tax-Related Items are satisfied by withholding Shares, for tax purposes, the Participant will be deemed to have been issued the full number of Shares subject to the exercised Stock Option, notwithstanding that a number of the Shares is held back solely for the purpose of satisfying the withholding obligations for the Tax-Related Items.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The Company shall not be obligated to honor an exercise or deliver any Shares to the Participant unless and until the Participant shall have paid or otherwise satisfied in full, any withholding obligation for Tax-Related Items resulting from the Stock Option or the Shares subject to the Stock Option.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. <u>Nature of Grant</u>. By accepting the Stock Option, the Participant acknowledges, understands and agrees that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the Plan is established voluntarily by the Company, is wholly discretionary in nature and may be modified, amended, suspended, or terminated by the Company at any time, to the extent permitted by the Plan;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the Plan is operated and the Stock Option is granted solely by the Company and only the Company is a party to this Agreement; accordingly, any rights the Participant may have under this Agreement may be raised only against the Company but not any Subsidiary (including, but not limited to, the Service Recipient);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) no Company Subsidiary (including, but not limited to, the Service Recipient) has any obligation to make any payment of any kind to the Participant under this Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the grant of the Stock Option is exceptional, voluntary and occasional and does not create any contractual or other right to receive future grants of stock options, or benefits in lieu of stock options, even if stock options have been granted in the past;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) all decisions with respect to future grants of stock options or other grants, if any, will be at the sole discretion of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) the Stock Option and the Participant's participation in the Plan shall not create a right of Employment with the Company or any Subsidiary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) the Stock Option and the Participant's participation in the Plan shall not be interpreted as forming or amending an employment or service contract with the Company or the Service Recipient, and shall not interfere with the ability of the Company, the Service Recipient or any Subsidiary, as applicable, to terminate the Participant's Employment (if any);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) the Participant is voluntarily participating in the Plan;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(n) no claim or entitlement to compensation or damages shall arise from (i) forfeiture of any portion of the Stock Option resulting from the Participant's termination of Employment (for any reason whatsoever and regardless of whether or not later found to be invalid or in breach of applicable laws in the jurisdiction where the Participant is providing service or the terms of the Participant's employment or other service agreement, if any), or (ii) the application of any clawback or recoupment policy adopted by the Company or imposed by applicable laws;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(q) neither the Company, the Service Recipient nor any Subsidiary shall be liable for any foreign exchange rate fluctuation between the Participant's local currency and the U.S. dollar that may affect the value of the Stock Option or of any amounts due to the Participant pursuant to the exercise of the Stock Option or the subsequent sale of any Shares acquired upon exercise.

The Company and the Service Recipient collect, process and use certain personal information about the Participant, including, but not limited to, the Participant's name, home address, telephone number, email address, date of birth, social insurance number, passport or other identification number, salary, nationality, job title, any Shares or directorships held in the Company, details of all Stock Options granted under the Plan or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in the Participant's favor ("Data"), for the purpose of implementing, administering and managing the Plan. Where required, the legal basis for the collection and processing of Data is the Participant's consent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) <u>Stock Plan Administration Service Providers</u>. The Company transfers Data to Morgan Stanley Smith Barney, LLC and its affiliated company, E\*TRADE Financial Corporate Services, Inc. (collectively "E\*TRADE"), an independent service provider based in the U.S., which is assisting the Company with the implementation, administration and management of the Plan. The Company may select a different service provider or additional service providers and share Data with such other provider serving in a similar manner. The Participant may be asked to agree on separate terms and data processing practices with E\*TRADE, with such agreement being a condition to the ability to participate in the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) <u>International Data Transfers</u>. The Company and its service providers, including E\*TRADE, are based in the U.S. The Participant's country or jurisdiction may have different data privacy laws and protections than the U.S. Where required, the legal basis for the transfer of Data to these recipients is the Participant's consent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) <u>Data Retention</u>.

Participation in the Plan is voluntary and the Participant is providing the consents herein on a voluntary basis. The Participant understands that the Participant may request to stop the transfer and processing of the Participant's Data for purposes of the Participant's participation in the Plan and that the Participant's compensation from or Employment with the Service Recipient will not be affected. The only consequence of refusing or withdrawing consent is that the Company would not be able to allow the Participant to participate in the Plan. The Participant understands that the Participant's Data will still be processed in relation to the Participant's Employment and for record-keeping purposes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) <u>Data Subject Rights</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. <u>Section 280G</u>. If any payment or benefit that the Participant may receive in respect of the Stock Option (the "**Payment**"), would (i) constitute a "parachute payment" within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the "**Excise Tax**"), then such Payment shall be reduced to the Reduced Amount. The "**Reduced Amount**" shall be either (A) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (B) the largest portion, up to and including the total amount, of the Payment, whichever of the amounts determined under (A) and (B), after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in the Participant's receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. <u>Provisions of the Plan</u>. This Agreement is subject in its entirety to the provisions of the Plan, which are incorporated herein by reference. A copy of the Plan as in effect on the Date of Grant has been made available to the Participant. By accepting, or being deemed to have accepted, the Stock Option, the Participant agrees to be bound by the terms of the Plan and this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13. <u>Electronic Delivery and Participation</u>. The Company may, in its sole discretion, decide to deliver any documents related to current or future participation in the Plan by electronic means.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14. <u>No Advice Regarding Grant</u>. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding the Participant's participation in the Plan or the Participant's receipt, vesting or exercise of the Stock Option or the Shares allocated thereto or the sale of such Shares. The Participant should consult with the Participant's own personal tax, legal and financial advisors regarding participation in the Plan and the Stock Option before accepting the Stock Option or otherwise taking any action related to the Stock Option or the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15. <u>Language</u>. The Participant acknowledges that the Participant is sufficiently proficient in English, or has consulted with an advisor who is sufficiently proficient in English, so as to allow the Participant to understand the terms and conditions of this Agreement and the Plan. If the Participant received this Agreement, or any other document related to the Stock Option and/or the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control, unless otherwise required by applicable laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;16. <u>Country-Specific Provisions</u>. The Stock Option shall be subject to any additional terms and conditions set forth for the Participant's country in the Appendix. Moreover, if the Participant relocates to one of the countries included in the Appendix, the additional terms and conditions for such country will apply to the Participant to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons. The Appendix constitutes part of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;17. <u>Imposition of Other Requirements</u>. The Company reserves the right to impose other requirements on the Stock Option and the Shares issuable upon exercise thereof, to the extent the Company determines it is necessary or advisable in order to comply with local laws or facilitate the administration of the Plan, and to require the Participant to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;18. <u>Waiver</u>. The Participant acknowledges that a waiver by the Company of breach of any provision of this Agreement shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach by the Participant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19. <u>Severability</u>. If any portion of this Agreement or any action taken under this Agreement is held illegal or invalid for any reason, the illegality or invalidity will not affect the remaining parts of this Agreement, and this Agreement will be construed and enforced as if the illegal or invalid provisions had been excluded, and the illegal or invalid action will be null and void.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;20. <u>Insider Trading/Market Abuse Laws</u>. Depending on the Participant's country or broker's country, or the country in which the Shares are listed, the Participant may be subject to insider trading restrictions and/or market abuse laws in applicable jurisdictions, which may affect the Participant's ability to accept, acquire, sell or attempt to sell, or otherwise dispose of the Shares, rights to Shares (*e.g.*, the Stock Option) or rights linked to the value of Shares, during such times as the Participant is considered to have "inside information" regarding the Company (as defined by applicable laws). Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. The Participant acknowledges that it is the Participant's responsibility to comply with any applicable restrictions, and should consult a personal legal advisor on this matter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;21. <u>Foreign Asset/Account Reporting, Exchange Control and Tax Reporting</u>.

**APPENDIX**

**TO THE**

**GLOBAL NON-STATUTORY STOCK OPTION AGREEMENT**

**<u>COUNTRY-SPECIFIC PROVISIONS</u>**

**<u>FOR PARTICIPANTS OUTSIDE OF THE U.S.</u>**

Except as otherwise defined herein, all capitalized terms used herein have the same meaning as in the Plan and/or the Agreement to which this Appendix is attached.

***Terms and Conditions***

This Appendix includes additional terms and conditions that govern the Stock Option if the Participant resides and/or works in one of the countries listed below. If the Participant is a citizen or resident (or is considered as such for local law purposes) of a country other than the country in which the Participant is currently residing and/or working, or if the Participant transfers to another country after the Date of Grant, the Administrator shall, in its discretion, determine to what extent the terms and conditions contained herein shall be applicable to the Participant.

***Notifications***

This Appendix also includes information regarding securities, exchange controls, tax and certain other issues of which the Participant should be aware with respect to participation in the Plan. The information is based on the securities, exchange control, tax and other laws in effect in the respective countries as of August 2024. Such laws are often complex and change frequently. As a result, the Company strongly recommends that the Participant not rely on the information noted herein as the only source of information relating to the consequences of participation in the Plan because the information may be out of date when the Participant exercises the Stock Option or sells Shares acquired under the Plan.

In addition, the information contained herein is general in nature and may not apply to the Participant's particular situation, and the Company is not in a position to assure the Participant of any particular result. Accordingly, the Participant should seek appropriate professional advice as to how the applicable laws in the Participant's country may apply to the Participant's situation.

Finally, if the Participant is a citizen or resident (or is considered as such for local law purposes) of a country other than the one in which the Participant is currently residing and/or working, or if the Participant transfers to another country after the Date of Grant, the information contained herein may not be applicable to the Participant in the same manner.

**<u>CHINA</u>**

***Terms and Conditions***

*The following provisions apply if the Participant is subject to exchange control restrictions imposed by the State Administration of Foreign Exchange ("SAFE"), as determined by the Company in its sole discretion:*

<u>Exercisability of Stock Option</u>. In addition to the vesting conditions set forth in the Agreement, the Stock Option shall not vest nor be exercisable until all necessary exchange control and other approvals from SAFE or its local counterpart have been received by the Company or one of its Chinese Subsidiaries under applicable exchange control rules with respect to the Plan and the awards thereunder (the "**SAFE Approval Date**"). The Participant must continue to provide service through each exercisability date and through the SAFE Approval Date to be able to exercise the Stock Option. Should the SAFE Approval Date occur after any of the exercisability dates, the Participant will (i) receive a credit for any vesting that would have occurred under the exercisability schedule once the SAFE Approval Date occurs, and (ii) continue to vest in accordance with the exercisability schedule following the SAFE Approval Date, provided that the Participant has not experienced a termination of Employment as of the SAFE Approval Date and is otherwise entitled to exercise the Stock Option pursuant to the terms of any applicable SAFE approval or regulations.

If the Company is unable to complete the SAFE registration or maintain the registration, no shares of Stock subject to the Stock Option shall be issued and the Company has the sole discretion to allow any vested Stock Option to be settled in cash paid through local payroll in an amount equal to the Fair Market Value of the Shares underlying the Stock Option on the applicable date of exercise, less the total exercise price and any withholding for Tax-Related Items.

Furthermore, notwithstanding any provision in the Agreement, if the Participant experiences a termination of Employment before the SAFE Approval Date, the Stock Option shall be forfeited, unless the Company determines in its discretion that any portion of the Stock Option that may otherwise have vested and become exercisable in accordance with the terms of the Agreement may be exercised in compliance with applicable SAFE regulations and restrictions.

Finally, notwithstanding any provision in the Agreement, if the Participant experiences a termination of Employment after the SAFE Approval Date, the Stock Option, to the extent that vested and exercisable as of the termination of Employment, may be exercised by the Participant only within such time period as required by the Company in accordance with SAFE requirements.

<u>Shares Must Remain with Company's Designated Broker</u>*.* The Participant agrees to hold any Shares received upon exercise of the Stock Option with the Company's designated broker until the Shares are sold. The limitation shall apply to all Shares issued to the Participant under the Plan, whether or not the Participant has experienced a termination of Employment.

<u>Manner of Exercise</u>. Notwithstanding any provision in the Agreement, the Participant must pay the exercise price by using a "cashless exercise" whereby the Participant delivers to the Company a properly executed exercise election together with irrevocable instructions to the broker to promptly delivery to the Company cash or a check payable and acceptable to the Company to pay the exercise price. The Company reserves the right to provide the Participant with additional methods of payment depending on the development of local law.

<u>Forced Sale of Shares</u>. The Company has the discretion to arrange for the sale of the Shares issued upon exercise of the Stock Option, either immediately upon exercise or at any time thereafter. In any event, if the Participant's Employment terminates, the Participant will be required to sell any Shares acquired under the Plan within such time period as required by the Company in accordance with SAFE requirements. Any Shares remaining in the brokerage account at the end of this period shall be sold by the broker (on behalf of the Participant and the Participant hereby authorizes such sale). The Participant agrees to sign any additional agreements, forms and/or consents that reasonably may be requested by the Company (or the Company's designated broker) to effectuate the sale of Shares (including, without limitation, as to the transfer of the sale proceeds and other exchange control matters noted below) and shall otherwise cooperate with the Company with respect to such matters. The Participant acknowledges that neither the Company nor the designated broker is under any obligation to arrange for the sale of shares at any particular price (it being understood that the sale will occur in the market) and that broker's fees and similar expenses may be incurred in any such sale. In any event, when the Shares are sold, the sale proceeds, less any withholding for Tax-Related Items, any broker's fees or commissions, and any similar expenses of the sale will be remitted to the Participant in accordance with applicable exchange control laws and regulations.

<u>Exchange Control Restrictions</u>. The Participant understands and agrees that the Participant will be required to immediately repatriate to China the proceeds from the sale of any Shares acquired under the Plan and any cash dividends paid on such Shares. The Participant further understands that such repatriation of proceeds may need to be effected through a special bank account established by the Company (or a Subsidiary), and the Participant hereby consents and agrees that any sale proceeds and cash dividends may be transferred to such special account by the Company (or a Subsidiary) on the Participant's behalf prior to being delivered to the Participant and that no interest shall be paid with respect to funds held in such account.

The proceeds may be paid to the Participant in U.S. dollars or local currency at the Company's discretion. If the proceeds are paid to the Participant in U.S. dollars, the Participant understands that a U.S. dollar bank account in China must be established and maintained so that the proceeds may be deposited into such account. If the proceeds are paid to the Participant in local currency, the Participant acknowledges that the Company (or its Subsidiaries) are under no obligation to secure any particular exchange conversion rate and that the Company (or its Subsidiaries) may face delays in converting the proceeds to local currency due to exchange control restrictions. The Participant agrees to bear any currency fluctuation risk between the time the shares are sold and the net proceeds are converted into local currency and distributed to the Participant. The Participant further agrees to comply with any other requirements that may be imposed by the Company (or its Subsidiaries) in the future in order to facilitate compliance with exchange control requirements in China.

<u>Administration</u>. The Company (or its Subsidiaries) shall not be liable for any costs, fees, lost interest or dividends or other losses that the Participant may incur or suffer resulting from the enforcement of the terms of this Appendix or otherwise from the Company's operation and enforcement of the Plan, the Agreement and the Stock Option in accordance with any applicable laws, rules, regulations and requirements.

Such reports must be made either electronically using the "General Statistics Reporting Portal" ("**Allgemeine Meldeportal Statistik**") available on the Bundesbank website (<u>www.bundesbank.de</u>) or via such other method (*e.g.*, by email or telephone) as is permitted or required by Bundesbank.

**<u>ITALY</u>**

***Terms and Conditions***

<u>Plan Document Acknowledgement</u>. By accepting the Stock Option, the Participant acknowledges that the Participant has received a copy of the Plan, has reviewed the Plan and the Agreement in their entirety and fully understands and accepts all provisions of the Plan and Agreement.

The Participant further acknowledges that the Participant has read and specifically and expressly approves the following sections of the Agreement: Section 3: Exercise of the Stock Option, Section 5: Forfeiture; Recovery of Compensation, Section 6: Nontransferability, Section 7: Responsibility for Taxes, Section 9: Data Privacy Consent, Section 13: Electronic Delivery and Participation, Section 15: Language, and Section 17: Imposition of Other Requirements.

These reporting obligations will apply to the Participant if the Participant is the beneficial owner of foreign financial assets under Italian money laundering provisions. The Participant should consult with a personal tax advisor to ensure compliance with the applicable requirements.

**<u>SPAIN</u>**

***Terms and Conditions***

<u>Nature of Grant</u>. The following provision supplements Section 8 of the Agreement:

By accepting the Stock Option, the Participant consents to participation in the Plan and acknowledges that the Participant has received a copy of the Plan.

The Participant understands that the Company has unilaterally, gratuitously and in its sole discretion decided to grant the Stock Option under the Plan to individuals who may be Employees. The decision is limited and entered into based upon the express assumption and condition that any Stock Option will not economically or otherwise bind the Company or any Subsidiary, including the Service Recipient, on an ongoing basis, other than as expressly set forth in the Agreement. Consequently, the Participant understands that the Stock Option is given on the assumption and condition that the Stock Option shall not become part of any employment or other service contract (whether with the Company or any Subsidiary, including the Service Recipient) and shall not be considered a mandatory benefit, salary for any purpose (including severance compensation) or any other right whatsoever. Furthermore, the Participant understands and freely accepts that there is no guarantee that any benefit whatsoever shall arise from the Stock Option, which is gratuitous and discretionary, since the future value of the Stock Option and the underlying Shares is unknown, indeterminable, and unpredictable.

Further, the Participant's participation in the Plan is expressly conditioned on the Participant's continued and active Employment, such that, unless otherwise set forth in the Plan, if the Participant's Employment terminates for any reason, the Participant's unvested Stock Options will be canceled without entitlement to any Shares. This will be the case, for example, even if (a) the Participant is considered to be unfairly dismissed without good cause (*i.e.*, subject to a "*despido improcedente*"); (b) the Participant is dismissed for disciplinary or objective reasons or due to a collective dismissal; (c) the Participant's Employment ceases due to a change of work location, duties or any other employment or contractual condition; (d) the Participant's Employment ceases due to a unilateral breach of contract by the Company or any Subsidiary; or (e) the Participant's Employment terminates for any other reason whatsoever.

***Notifications***

<u>Securities Law Information</u>. The grant of the Stock Option and the Shares issued pursuant to the exercise of the Stock Option are considered a private placement outside the scope of Spanish laws on public offerings and issuances of securities. Neither the Plan nor the Agreement have been registered with the *Comisión Nacional del Mercado de Valores* and do not constitute a public offering prospectus.

<u>Exchange Control Information</u>. The Participant is required to electronically declare to the Bank of Spain any security accounts (including brokerage accounts held abroad), as well as the securities (including Shares acquired under the Plan) held in such accounts if the value of the transactions for all such accounts during the prior tax year or the balances of such accounts as of December 31 of the prior tax year exceeds EUR 1 million. Different thresholds and deadlines to file this declaration apply. However, if neither such transactions during the immediately preceding year nor the balances / positions as of December 31 exceed EUR 1 million, no such declaration must be filed unless expressly required by the Bank of Spain. If any such thresholds were exceeded during the current year, the Participant may be required to file the relevant declaration corresponding to the prior year, however, a summarized form of declaration may be available. The Participant should consult with a personal legal advisor to ensure compliance with applicable reporting requirements.

<u>Foreign Asset/Account Reporting Information</u>. To the extent the Participant holds rights or assets outside of Spain with a value in excess of EUR 50,000 per type of right or asset (*e.g.*, Shares, cash, etc.) as of December 31 each year, the Participant will be required to report information on such rights and assets on the annual tax return for such year. After such rights and assets are initially reported, the reporting obligation will apply for subsequent years only if the value of any previously-reported rights or assets increases by more than EUR 20,000. The Participant should consult with a personal tax advisor to ensure compliance with applicable reporting requirements.

**ZENAS BIOPHARMA, INC.<br> 2026 INDUCEMENT PLAN**

**<u>Global Restricted Stock Unit Agreement</u>**

This agreement, including the additional terms and conditions for certain countries, set forth in the appendix attached hereto (the "**Appendix**" and, together with this Global Restricted Stock Unit Agreement, the "**Agreement**") evidences a grant (the "**Award**") of Restricted Stock Units ("**RSUs**") by Zenas BioPharma, Inc., a Delaware corporation (the "**Company**"), to the individual named above (the "**Participant**"), pursuant to and subject to the terms of the Zenas BioPharma, Inc. 2026 Inducement Plan (as from time to time amended and in effect, the "**Plan**"). Except as otherwise defined herein, all capitalized terms used herein have the same meaning as in the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. <u>Grant of RSUs</u>. The Company grants to the Participant on the date set forth above (the "**Date of Grant**") the number of Restricted Stock Units ("**RSUs**") set forth above, giving the Participant the conditional right to receive, without payment and pursuant to and subject to the terms and conditions set forth in this Agreement and in the Plan, one share of Stock (a "**Share**") with respect to each RSU subject to this Award, subject to adjustment pursuant to Section 7 of the Plan in respect of transactions occurring after the date hereof.

The RSUs are granted to the Participant in connection with the Participant's Employment as an employee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. <u>Vesting</u>. Unless earlier terminated, forfeited, relinquished or expired, the RSUs will vest as follows: [INSERT VESTING SCHEDULE].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. <u>Cessation of Employment</u>. Except as (a) the Administrator may determine in its discretion or (b) expressly provided for in an employment agreement between the Participant and the Company that is in effect at the time of the Participant's termination of Employment, if the Participant's Employment ceases for any reason, the RSUs, to the extent not then vested, will be immediately forfeited for no consideration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. <u>Delivery of Shares</u>. Subject to Section 5 below, the Company shall, as soon as practicable upon the vesting of any RSUs (but in no event later than thirty (30) days following the date on which such RSUs vest), effect delivery of the Shares with respect to such vested RSUs to the Participant (or, in the event of the Participant's death, to the person to whom the Award has passed by will or the laws of descent and distribution). No Shares will be issued pursuant to this Award unless and until all legal requirements applicable to the issuance or transfer of such Shares have been complied with to the satisfaction of the Administrator.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. <u>Forfeiture; Recovery of Compensation</u>. The Administrator may cancel, rescind, withhold or otherwise limit or restrict this Award at any time if the Participant is not in compliance with all applicable provisions of this Agreement and the Plan. By accepting, or being deemed to have accepted, the RSUs, the Participant expressly acknowledges and agrees that his or her rights, and those of any permitted transferee, with respect to the RSUs, including the right to any Shares acquired in respect of the RSUs and any amounts received in respect thereof, are subject to Section 6(a)(v) of the Plan (including any successor provision). The Participant further agrees to be bound by the terms of any applicable clawback or recoupment policy of the Company, including the Company's Policy for Recoupment of Incentive Compensation Policy. Nothing in the preceding sentence will be construed as limiting the general application of Section 11 of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. <u>Nontransferability</u>. The RSUs may not be transferred except as expressly permitted under Section 6(a)(iii) of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. <u>Responsibility for Taxes</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Participant acknowledges that, regardless of any action taken by the Company or, if different, the Subsidiary that employs the Participant (the "**Service Recipient**"), the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to the Participant's participation in the Plan and legally applicable or deemed applicable to the Participant ("**Tax-Related Items**") is and remains the Participant's responsibility and may exceed the amount (if any) actually withheld by the Company or the Service Recipient. The Participant further acknowledges that the Company and/or the Service Recipient (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the RSUs, including, but not limited to, the grant, vesting or settlement of the RSUs, or the subsequent sale of Shares acquired pursuant to such grant; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the RSUs to reduce or eliminate the Participant's liability for Tax-Related Items or achieve any particular tax result. Further, if the Participant is subject to Tax-Related Items in more than one jurisdiction, the Participant acknowledges that the Company and/or the Service Recipient (or former Service Recipient, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In connection with any relevant taxable or tax withholding event, as applicable, the Participant agrees to make adequate arrangements satisfactory to the Company and/or the Service Recipient to satisfy all Tax-Related Items. In this regard, the Participant hereby authorizes the Company and/or the Service Recipient, or their respective agents, at their discretion, to satisfy any applicable withholding obligations or rights for Tax-Related Items (as applicable) by one or a combination of the following methods:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) requiring the Participant to make a payment in a form acceptable to the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) withholding from the Participant's salary, wages, or any other amounts payable to the Participant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) withholding from proceeds of the sale of Shares otherwise issuable upon settlement of the RSUs either through a voluntary sale or through a mandatory sale arranged by the Company (on the Participant's behalf pursuant to this authorization without further consent); it being understood that, unless otherwise determined by the Committee, the Company shall automatically satisfy any tax withholding obligations by causing such number of Shares to be sold through a sell-to-cover arrangement and the Participant agrees that the Participant shall bear all costs associated with the sale of shares under such arrangements; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) any other method of withholding determined by the Company and to the extent required by applicable laws or the Plan, approved by the Compensation Committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Company may withhold or account for Tax-Related Items by considering statutory or other withholding rates, including up to the maximum rates applicable in the Participant's jurisdiction(s). If the application of the withholding rate leads to over-withholding, the Participant may receive a refund of any over-withheld amount in cash from the Company or the Service Recipient (with no entitlement to the equivalent in Shares) or, if not refunded, the Participant may be able to seek a refund from the local tax authorities. If the application of the withholding rate leads to under-withholding, the Participant may be required to pay any additional Tax-Related Items directly to the applicable tax authority or to the Company and/or the Service Recipient. If the obligations for Tax-Related Items are satisfied by withholding Shares, for tax purposes, the Participant will be deemed to have been issued the full number of Shares subject to the vested RSUs, notwithstanding that a number of the Shares is held back solely for the purpose of satisfying the withholding obligations for the Tax-Related Items.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The Company shall not be obligated to deliver any Shares to the Participant unless and until the Participant shall have paid or otherwise satisfied in full, any withholding obligation for Tax-Related Items resulting from the Award or the RSUs subject to the Award.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. <u>Nature of Grant</u>. By accepting the Award, the Participant acknowledges, understands and agrees that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the Plan is established voluntarily by the Company, is wholly discretionary in nature and may be modified, amended, suspended, or terminated by the Company at any time, to the extent permitted by the Plan;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the Plan is operated and the Award is granted solely by the Company and only the Company is a party to this Agreement; accordingly, any rights the Participant may have under this Agreement may be raised only against the Company but not any Subsidiary (including, but not limited to, the Service Recipient);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) no Subsidiary of the Company (including, but not limited to, the Service Recipient) has any obligation to make any payment of any kind to the Participant under this Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the grant of the Award is exceptional, voluntary and occasional and does not create any contractual or other right to receive future grants of restricted stock units, or benefits in lieu of restricted stock units, even if restricted stock units have been granted in the past;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) all decisions with respect to future grants of restricted stock units or other grants, if any, will be at the sole discretion of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) the Award and the Participant's participation in the Plan shall not create a right of Employment with the Company or any Subsidiary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) the Award and the Participant's participation in the Plan shall not be interpreted as forming or amending an employment or service contract with the Company or the Service Recipient, and shall not interfere with the ability of the Company, the Service Recipient or any Subsidiary, as applicable, to terminate the Participant's Employment (if any);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) the Participant is voluntarily participating in the Plan;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Award and any Shares acquired under the Plan, and the income from and value of the same, are not intended to replace any pension rights or compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) the Award and any Shares acquired under the Plan, and the income from and value of the same, are not part of normal or expected compensation for any purposes, including but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards, holiday pay, pension or retirement or welfare benefits or similar payments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) the future value of the Shares underlying the Award is unknown, indeterminable, and cannot be predicted with certainty;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) no claim or entitlement to compensation or damages shall arise from (i) forfeiture of any portion of the Award resulting from the Participant's termination of Employment (for any reason whatsoever and regardless of whether or not later found to be invalid or in breach of applicable laws in the jurisdiction where the Participant is providing service or the terms of the Participant's employment or other service agreement, if any), or (ii) the application of any clawback or recoupment policy adopted by the Company or imposed by applicable laws;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m) unless otherwise agreed with the Company in writing, the Award and the Shares subject to the Award, and the income from and value of the same, are not granted as consideration for, or in connection with, the service the Participant may provide as a director of a Subsidiary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(n) unless otherwise provided in the Plan or by the Company in its discretion, the Award and the benefits evidenced by this Agreement do not create any entitlement to have the Award or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the Shares; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(o) neither the Company, the Service Recipient nor any Subsidiary shall be liable for any foreign exchange rate fluctuation between the Participant's local currency and the U.S. dollar that may affect the value of the Shares or of any amounts due to the Participant pursuant to the settlement of the Award or the subsequent sale of any Shares acquired upon settlement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. <u>Data Privacy Consent</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>Data Collection and Usage</u>. The Company and the Service Recipient collect, process and use certain personal information about the Participant, including, but not limited to, the Participant's name, home address, telephone number, email address, date of birth, social insurance number, passport or other identification number, salary, nationality, job title, any Shares or directorships held in the Company, details of all RSUs granted under the Plan or any other entitlement to Shares awarded, canceled, vested, unvested or outstanding in the Participant's favor ("**Data**"), for the purpose of implementing, administering and managing the Plan. Where required, the legal basis for the collection and processing of Data is the Participant's consent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) <u>Stock Plan Administration Service Providers</u>. The Company transfers Data to Morgan Stanley Smith Barney, LLC and its affiliated company, E\*TRADE Financial Corporate Services, Inc. (collectively "**E\*TRADE**"), an independent service provider based in the U.S., which is assisting the Company with the implementation, administration and management of the Plan. The Company may select a different service provider or additional service providers and share Data with such other provider serving in a similar manner. The Participant may be asked to agree on separate terms and data processing practices with E\*TRADE, with such agreement being a condition to the ability to participate in the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) <u>International Data Transfers</u>. The Company and its service providers, including E\*TRADE, are based in the U.S. The Participant's country or jurisdiction may have different data privacy laws and protections than the U.S. Where required, the legal basis for the transfer of Data to these recipients is the Participant's consent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) <u>Data Retention</u>. The Company will hold and use Data only as long as is necessary to implement, administer and manage the Participant's participation in the Plan, or as required to comply with applicable law, exercise or defense of legal rights, and archiving, back-up and deletion processes. This period may extend beyond the Participant's period of Employment with the Service Recipient.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) <u>Voluntariness and Consequences of Consent Denial or Withdrawal</u>. Participation in the Plan is voluntary and the Participant is providing the consents herein on a voluntary basis. The Participant understands that the Participant may request to stop the transfer and processing of the Participant's Data for purposes of the Participant's participation in the Plan and that the Participant's compensation from or Employment with the Service Recipient will not be affected. The only consequence of refusing or withdrawing consent is that the Company would not be able to allow the Participant to participate in the Plan. The Participant understands that the Participant's Data will still be processed in relation to the Participant's Employment and for record-keeping purposes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) <u>Data Subject Rights</u>. The Participant may have a number of rights under data privacy laws in the Participant's jurisdiction.

To receive clarification regarding these rights or to exercise these rights, the Participant can contact DPO@zenasbio.com.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. <u>Section 280G</u>. If any payment or benefit that the Participant may receive in respect of the RSUs or otherwise from the Company or any Subsidiary (the "**Payment**") would (i) constitute a "parachute payment" within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the "**Excise Tax**"), then such Payment shall be reduced to the Reduced Amount. The "**Reduced Amount**" shall be either (A) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (B) the largest portion, up to and including the total amount, of the Payment, whichever of the amounts determined under (A) and (B), after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in the Participant's receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. <u>Provisions of the Plan</u>. This Agreement is subject in its entirety to the provisions of the Plan, which are incorporated herein by reference. A copy of the Plan as in effect on the Date of Grant has been made available to the Participant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13. <u>Electronic Delivery and Participation</u>. The Company may, in its sole discretion, decide to deliver any documents related to current or future participation in the Plan by electronic means. The Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the company or a third party designated by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14. <u>No Advice Regarding Grant</u>. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding the Participant's participation in the Plan or the Participant's receipt, vesting or settlement of the RSUs or the Shares allocated thereto or the sale of such Shares. The Participant should consult with the Participant's own personal tax, legal and financial advisors regarding participation in the Plan and the RSUs before accepting the Award or otherwise taking any action related to the Award or the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15. <u>Language</u>. The Participant acknowledges that the Participant is sufficiently proficient in English, or has consulted with an advisor who is sufficiently proficient in English, so as to allow the Participant to understand the terms and conditions of this Agreement and the Plan. If the Participant received this Agreement, or any other document related to the Award and/or the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control, unless otherwise required by applicable laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;16. <u>Country-Specific Provisions</u>. The Award shall be subject to any additional terms and conditions set forth for the Participant's country in the Appendix. Moreover, if the Participant relocates to one of the countries included in the Appendix, the additional terms and conditions for such country will apply to the Participant to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons. The Appendix constitutes part of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;17. <u>Imposition of Other Requirements</u>. The Company reserves the right to impose other requirements on the RSUs and the Shares issuable upon vesting and settlement thereof, to the extent the Company determines it is necessary or advisable in order to comply with local laws or facilitate the administration of the Plan, and to require the Participant to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;18. <u>Waiver</u>. The Participant acknowledges that a waiver by the Company of breach of any provision of this Agreement shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach by the Participant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19. <u>Severability</u>. If any portion of this Agreement or any action taken under this Agreement is held illegal or invalid for any reason, the illegality or invalidity will not affect the remaining parts of this Agreement, and this Agreement will be construed and enforced as if the illegal or invalid provisions had been excluded, and the illegal or invalid action will be null and void.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;20. <u>Insider Trading/Market Abuse Laws</u>. Depending on the Participant's country or broker's country, or the country in which the Shares are listed, the Participant may be subject to insider trading restrictions and/or market abuse laws in applicable jurisdictions, which may affect the Participant's ability to accept, acquire, sell or attempt to sell, or otherwise dispose of the Shares, rights to Shares (*e.g.*, the RSUs) or rights linked to the value of Shares, during such times as the Participant is considered to have "inside information" regarding the Company (as defined by applicable laws). Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. The Participant acknowledges that it is the Participant's responsibility to comply with any applicable restrictions, and should consult a personal legal advisor on this matter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;21. <u>Foreign Asset/Account Reporting, Exchange Control and Tax Reporting</u>. The Participant may be subject to foreign asset/account, exchange control and/or tax reporting requirements as a result of the acquisition, holding and/or transfer of Shares or cash (including dividends and the proceeds arising from the sale of Shares) derived from participation in the Plan in, to and/or from a brokerage/bank account or legal entity located outside the Participant's country.

**APPENDIX**

**TO THE**

**GLOBAL RESTRICTED STOCK UNIT AGREEMENT**

**<u>COUNTRY-SPECIFIC PROVISIONS</u>**

**<u>FOR PARTICIPANTS OUTSIDE OF THE U.S.</u>**

Except as otherwise defined herein, all capitalized terms used herein have the same meaning as in the Plan and/or the Agreement to which this Appendix is attached.

***Terms and Conditions***

This Appendix includes additional terms and conditions that govern the Award if the Participant resides and/or works in one of the countries listed below. If the Participant is a citizen or resident (or is considered as such for local law purposes) of a country other than the country in which the Participant is currently residing and/or working, or if the Participant transfers to another country after the Date of Grant, the Administrator shall, in its discretion, determine to what extent the terms and conditions contained herein shall be applicable to the Participant.

***Notifications***

This Appendix also includes information regarding securities, exchange controls, tax and certain other issues of which the Participant should be aware with respect to participation in the Plan. The information is based on the securities, exchange control, tax and other laws in effect in the respective countries as of April 2025. Such laws are often complex and change frequently. As a result, the Company strongly recommends that the Participant not rely on the information noted herein as the only source of information relating to the consequences of participation in the Plan because the information may be out of date when the Participant vests in the Award or sells Shares acquired under the Plan.

In addition, the information contained herein is general in nature and may not apply to the Participant's particular situation, and the Company is not in a position to assure the Participant of any particular result. Accordingly, the Participant should seek appropriate professional advice as to how the applicable laws in the Participant's country may apply to the Participant's situation.

Finally, if the Participant is a citizen or resident (or is considered as such for local law purposes) of a country other than the one in which the Participant is currently residing and/or working, or if the Participant transfers to another country after the Date of Grant, the information contained herein may not be applicable to the Participant in the same manner.

**<u>CHINA</u>**

***Terms and Conditions***

*The following provision applies if the Participant is subject to exchange control restrictions and regulations in the People's Republic of China ()"**PRC**"), including the requirements imposed by the PRC State Administration of Foreign Exchange ("**SAFE**"), as determined by the Company in its sole discretion:*

<u>Conditions for Settlement of Award</u>. In addition to the vesting conditions set forth in the Agreement, the RSUs shall not vest and no Shares will be issued to the Participant in settlement of the RSUs unless and until all necessary exchange control and other approvals from SAFE or its local counterpart have been received by the Company or one of its Chinese Subsidiaries under applicable exchange control rules with respect to the Plan and the awards thereunder ("**SAFE Approval Date**"). The Participant must continue to provide service through each vesting date and through the SAFE Approval Date to be able to vest in the RSUs. Should the SAFE Approval Date occur after any of the vesting dates, the Participant will (i) receive a credit for any vesting that would have occurred under the vesting schedule once the SAFE Approval Date occurs, and (ii) continue to vest in accordance with the vesting schedule following the SAFE Approval Date, provided that the Participant has not experienced a termination of Employment as of the SAFE Approval Date and is otherwise entitled to vest in the RSUs pursuant to the terms of any applicable SAFE approval or regulations.

If the Company is unable to complete the SAFE registration or maintain the registration, no Shares subject to the RSUs shall be issued and the Company has the sole discretion to allow any vested RSUs to be settled in cash paid through local payroll in an amount equal to the Fair Market Value of the Shares underlying the RSUs, less any withholding for Tax-Related Items.

Furthermore, notwithstanding any provision in the Agreement, if the Participant experiences a termination of Employment before the SAFE Approval Date, the RSUs shall be forfeited, unless the Company determines in its discretion that any portion of the RSUs that may otherwise have vested in accordance with the terms of the Agreement may be settled in compliance with applicable SAFE regulations and restrictions.

<u>Shares Must Remain with Company's Designated Broker</u>*.* The Participant agrees to hold any Shares received pursuant to the Plan with the Company's designated broker until the Shares are sold. The limitation shall apply to all Shares issued to the Participant under the Plan, whether or not the Participant has experienced a termination of Employment.

<u>Forced Sale of Shares</u>. The Company has the discretion to arrange for the sale of the Shares issued upon vesting of the RSUs, either immediately upon vesting or at any time thereafter. In any event, if the Participant's Employment terminates, the Participant will be required to sell any Shares acquired under the Plan within such time period as required by the Company in accordance with SAFE requirements. Any Shares remaining in the brokerage account at the end of this period shall be sold by the broker (on behalf of the Participant and the Participant hereby authorizes such sale). The Participant agrees to sign any additional agreements, forms and/or consents that reasonably may be requested by the Company (or the Company's designated broker) to effectuate the sale of Shares (including, without limitation, as to the transfer of the sale proceeds and other exchange control matters noted below) and shall otherwise cooperate with the Company with respect to such matters. The Participant acknowledges that neither the Company nor the designated broker is under any obligation to arrange for the sale of shares at any particular price (it being understood that the sale will occur in the market) and that broker's fees and similar expenses may be incurred in any such sale. In any event, when the Shares are sold, the sale proceeds, less any withholding for Tax-Related Items, any broker's fees or commissions, and any similar expenses of the sale will be remitted to the Participant in accordance with applicable exchange control laws and regulations.

<u>Exchange Control Restrictions</u>. The Participant understands and agrees that the Participant will be required to immediately repatriate to China the proceeds from the sale of any Shares acquired under the Plan and any cash dividends paid on such Shares. The Participant further understands that such repatriation of proceeds may need to be effected through a special bank account established by the Company (or a Subsidiary), and the Participant hereby consents and agrees that any sale proceeds and cash dividends may be transferred to such special account by the Company (or a Subsidiary) on the Participant's behalf prior to being delivered to the Participant and that no interest shall be paid with respect to funds held in such account.

The proceeds may be paid to the Participant in U.S. dollars or local currency at the Company's discretion. If the proceeds are paid to the Participant in U.S. dollars, the Participant understands that a U.S. dollar bank account in China must be established and maintained so that the proceeds may be deposited into such account. If the proceeds are paid to the Participant in local currency, the Participant acknowledges that the Company (or its Subsidiaries) are under no obligation to secure any particular exchange conversion rate and that the Company (or its Subsidiaries) may face delays in converting the proceeds to local currency due to exchange control restrictions. The Participant agrees to bear any currency fluctuation risk between the time the shares are sold and the net proceeds are converted into local currency and distributed to the Participant. The Participant further agrees to comply with any other requirements that may be imposed by the Company (or its Subsidiaries) in the future in order to facilitate compliance with exchange control requirements in China.

<u>Administration</u>. The Company (or its Subsidiaries) shall not be liable for any costs, fees, lost interest or dividends or other losses that the Participant may incur or suffer resulting from the enforcement of the terms of this Appendix or otherwise from the Company's operation and enforcement of the Plan, the Agreement and the RSUs in accordance with any applicable laws, rules, regulations and requirements.

***Terms and Conditions***

<u>Nature of Grant</u>. The following provision supplements Section 8 of the Agreement:

By accepting the Award, the Participant consents to participation in the Plan and acknowledges that the Participant has received a copy of the Plan.

The Participant understands that the Company has unilaterally, gratuitously and in its sole discretion decided to grant Awards under the Plan to individuals who may be Employees. The decision is limited and entered into based upon the express assumption and condition that (i) any grant will not economically or otherwise bind the Company or any Subsidiary, including the Service Recipient, on an ongoing basis, other than as expressly set forth in the Agreement; (ii) the RSUs and any Shares acquired upon vesting shall not become part of any employment or other service contract (whether with the Company or any Subsidiary, including the Service Recipient) and shall not be considered a mandatory benefit, salary for any purpose (including severance compensation) or any other right whatsoever; and (iii) the RSUs will cease vesting upon the Participant's termination of Employment, as detailed below. The Participant understands and freely accepts that there is no guarantee that any benefit whatsoever shall arise from the Award, which is gratuitous and discretionary, since the future value of the RSUs and the underlying Shares is unknown, indeterminable, and unpredictable.

Further, the Participant's participation in the Plan is expressly conditioned on the Participant's continued and active Employment, such that, unless otherwise set forth in the Plan, if the Participant's Employment terminates for any reason, the Participant's unvested RSUs will be canceled without entitlement to any Shares. This will be the case, for example, even if (a) the Participant is considered to be unfairly dismissed without good cause (*i.e.*, subject to a "*despido improcedente*"); (b) the Participant is dismissed for disciplinary or objective reasons or due to a collective dismissal; (c) the Participant's Employment ceases due to a change of work location, duties or any other employment or contractual condition; (d) the Participant's Employment ceases due to a unilateral breach of contract by the Company or any Subsidiary; or (e) the Participant's Employment terminates for any other reason whatsoever.

However, if neither such transactions during the immediately preceding year nor the balances / positions as of December 31 exceed EUR 1 million, no such declaration must be filed unless expressly required by the Bank of Spain. If any such thresholds were exceeded during the current year, the Participant may be required to file the relevant declaration corresponding to the prior year, however, a summarized form of declaration may be available.

In such case, if the amount of any income tax due is not collected from or paid by the Participant within ninety (90) days of the end of the UK tax year in which an event giving rise to the indemnification described above occurs, the amount of any uncollected income taxes may constitute a benefit to the Participant on which additional income tax and national insurance contributions ("**NICs**") may be payable.
