(nor shall Shares subject to a Substitute Award be added to the Shares available for Awards under the Plan as provided above), except that Shares acquired by exercise of substitute Incentive Stock Options will count against the maximum number of
Shares that may be issued pursuant to the exercise of Incentive Stock Options under the Plan. Additionally, in the event that a company acquired by the Company or any Subsidiary or with which the Company or any Subsidiary combines has shares
available under a pre-existing plan approved by shareholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such pre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to
the holders of shares of the entities party to such acquisition or combination) may be used for Awards under the Plan and shall not reduce the Shares authorized for grant under the Plan (and Shares subject to such Awards shall not be added to the
Shares available for Awards under the Plan as provided above); provided that Awards using such available shares shall not be made after the date awards or grants could have been made under the terms of the
pre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were not Employees, Consultants or Directors prior to such acquisition or combination.

defended and indemnified by the Company to the extent permitted by Applicable Law and in the manner approved by the Administrator, on an after-tax basis, against all reasonable expenses, including
attorneys’ fees, actually and necessarily incurred in connection with the defense of any claim, investigation, action, suit or proceeding, or in connection with any appeal therein, to which they or any of them may be a party by reason of any
action taken or failure to act under or in connection with the Plan, or any Award granted hereunder, and against all amounts paid by them in settlement thereof (provided such settlement is approved by the Company) or paid by them in satisfaction of
a judgment in any such claim, investigation, action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such claim, investigation, action, suit or proceeding that such Person is liable for gross negligence, bad
faith or intentional misconduct; provided, however, that within thirty (30) days after the institution of such claim, investigation, action, suit or proceeding, such Person shall offer to the Company, in writing, the opportunity at the

authority to: (i) determine which Related Entities shall be covered by the Plan; (ii) determine which Employees, Directors, and Consultants are eligible to participate in the Plan; (iii) modify the terms and conditions of any Award
granted to an Employee, Director, or Consultant to comply with Applicable Law; (iv) establish sub-plans and modify exercise procedures and other terms and procedures, to the extent such actions may be
necessary or advisable; provided, however, that no such sub-plans and/or modifications shall increase the share limitations contained in Section 3(a); and (v) take any action, before or after an

under the Plan to permit selected Grantees the opportunity to elect to defer receipt of consideration upon exercise of an Award (other than an Award held by a Grantee who is a U.S. taxpayer), satisfaction of performance criteria, or other event that
absent the election would entitle the Grantee to payment or receipt of Shares or other consideration under an Award. The Administrator may establish the election procedures, the timing of such elections, the mechanisms for payments of, and accrual
of interest or other earnings, if any, on amounts, Shares or other consideration so deferred, and such other terms, conditions, rules and procedures that the Administrator deems advisable for the administration of any such deferral program.

pursuant to Section 3(e) above, the exercise or purchase price for the Award shall be determined in accordance with the provisions of the relevant instrument evidencing the agreement to issue such Award. 

(b) Consideration. Subject to Applicable Laws, the consideration to be paid for the Shares to be issued upon exercise or purchase of an

Award shall be exercised or purchased; 
 (iv) payment through a broker-dealer sale and remittance procedure pursuant to which the Grantee
(A) shall provide written instructions to a Company designated brokerage firm to effect the immediate sale of some or all of the purchased Shares and remit to the Company sufficient funds to cover the aggregate exercise price payable for the
purchased Shares and (B) shall provide written directives to the Company to deliver the certificates for the purchased Shares directly to such brokerage firm in order to complete the sale transaction; 

(v) any other consideration approved by the Administrator; or 

(vi) any combination of the foregoing methods of payment. 

The Administrator may at any time or from time to time, by adoption of or by amendment to the standard forms of Award Agreement described in
Section 4(b)(iii), or by other means, grant Awards which do not permit all of the foregoing forms of consideration to be used in payment for the Shares or which otherwise restrict one or more forms of consideration. 

(c) Tax Withholding. Each Grantee must pay the Company, or make provision satisfactory to the Administrator for payment of, any
taxes required by Applicable Law to be withheld in connection with such Grantee’s Awards by the date of the event creating the tax liability. The Company may deduct an amount sufficient to satisfy such tax obligations based on the applicable
statutory withholding rates (or such other rate as may be determined by the Company after considering the impact of Applicable Accounting Standards ) from any payment of any kind otherwise due to a Grantee. In the absence of a contrary determination
by the Company (or, with respect to withholding pursuant to clause (ii) below with respect to Awards held by Section 16 Persons, a contrary determination by the Administrator), all tax withholding obligations will be calculated based on
the maximum applicable statutory withholding rates. Subject to any Company insider trading policy (including blackout periods), Grantees may satisfy such tax obligations (i) in cash, by wire transfer of immediately available funds, by check
made payable to the order of the Company, provided that the Company may limit the use of the foregoing payment forms if one or more of the payment forms below is permitted, (ii) to the extent permitted by the Administrator, in whole or in part
by delivery of Shares, including Shares delivered by attestation and Shares retained from the Award creating the tax obligation, valued at their Fair Market Value on the date of delivery, (iii) if there is a public market for Shares at the time
the tax obligations are satisfied, unless the Company otherwise determines, (A) delivery (including electronically or telephonically to the extent permitted by the Company) of an irrevocable and unconditional undertaking by a broker acceptable
to the Company to deliver promptly to the Company sufficient funds to satisfy the tax obligations, or (B) delivery by the Grantee to the Company of a copy of irrevocable and unconditional instructions to a broker acceptable to the Company to
deliver promptly to the Company cash or a check sufficient to satisfy the tax withholding; provided that such amount is paid to the Company at such time as may be required by the Administrator, or (iv) to the extent permitted by the Company,
any combination of the foregoing payment forms approved by the Administrator. Notwithstanding any other provision of the Plan, the number of Shares which may be so delivered or retained pursuant to clause (ii) of the immediately preceding
sentence shall be limited to the number of Shares which have a Fair Market Value on the date of delivery or retention no greater than the aggregate amount of such liabilities based on the maximum individual statutory tax rate in the applicable
jurisdiction at the time of such withholding (or such other rate as may be required to avoid the liability classification of the applicable award under Applicable Accounting Standards); provided, however, to the extent such Shares were acquired by
Grantee from the Company as compensation, the Shares must have 

  
 11 













 
been held for the minimum period required by Applicable Accounting Standards to avoid a charge to the Company’s earnings for financial reporting purposes; provided, further, that, any such
Shares delivered or retained shall be rounded up to the nearest whole Share to the extent rounding up to the nearest whole Share does not result in the liability classification of the applicable Award under Applicable Accounting Standards. If any
tax withholding obligation will be satisfied under clause (ii) above by the Company’s retention of Shares from the Award creating the tax obligation and there is a public market for Shares at the time the tax obligation is satisfied, the
Company may elect to instruct any brokerage firm determined acceptable to the Company for such purpose to sell on the applicable Grantee’s behalf some or all of the Shares retained and to remit the proceeds of the sale to the Company or its
designee, and each Grantee’s acceptance of an Award under the Plan will constitute the Grantee’s authorization to the Company and instruction and authorization to such brokerage firm to complete the transactions described in this sentence.

 8. Exercise of Award. 

(a) Procedure for Exercise; Rights as a Shareholder. 

(i) Any Award granted hereunder shall be exercisable at such times and under such conditions as determined by the Administrator under the
terms of the Plan and specified in the Award Agreement. 
 (ii) An Award shall be deemed to be exercised when written or electronic notice
of such exercise in a form approved by the Administrator has been given to the Company in accordance with the terms of the Award by the Person entitled to exercise the Award and full payment for the Shares with respect to which the Award is
exercised and any applicable tax withholding, as provided in Section 7. 
 (b) Exercise of Award Following Termination of Continuous
Service. 
 (i) An Award may not be exercised after the termination date of such Award set forth in the Award Agreement and may be
exercised following the termination of a Grantee’s Continuous Service only to the extent provided in the Award Agreement. 
 (ii) Where
the Award Agreement permits a Grantee to exercise an Award following the termination of the Grantee’s Continuous Service for a specified period, the Award shall terminate to the extent not exercised on the last day of the specified period or
the last day of the original term of the Award, whichever occurs first. 
 (c) No Exercise in Violation of Applicable Law.
Notwithstanding the foregoing, regardless of whether an Award has otherwise become exercisable, the Award shall not be exercised if the Administrator (in its sole discretion) determines that an exercise would violate any Applicable Laws. 

9. Conditions Upon Issuance of Shares. 

(a) Shares shall not be issued pursuant to an Award unless the issuance and delivery of such Shares pursuant thereto shall comply with all
Applicable Laws, the M&A and the relevant Award Agreement. 

  
 12 













 (b) As a condition to the issuance of any Shares pursuant to an Award, the Company may
require the Person receiving such Shares to represent and warrant at the time of any Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company,
such a representation is required by any Applicable Laws. 
 (c) As a condition to the issuance of any Shares pursuant to an Award, the
applicable Award Agreement may require the Grantee to grant a power of attorney to the Board or any Person designated by the Board to exercise the voting rights with respect to the Shares and the Company may require the Person receiving such Shares
to acknowledge and agree to be bound by the provisions of the currently effective M&A, the Shareholders Agreements and other documents of the Company in relation to the Shares (if any), as if the Grantee is a holder of Ordinary Shares
thereunder. 
 10. Adjustments.  

(a) Equity Restructuring. In connection with any Equity Restructuring, notwithstanding anything to the contrary in this Section 10,
the Administrator will equitably adjust each outstanding Award as it deems appropriate to reflect the Equity Restructuring, which may include adjusting the number and type of securities subject to each outstanding Award and/or the Award’s
exercise price or grant price (if applicable), granting new Awards to Grantees, and making a cash payment to Grantees. The adjustments provided under this Section 10 will be nondiscretionary and final and binding on the affected Grantee
and the Company; provided that the Administrator will determine whether an adjustment is equitable. 
 (b) Corporate Transactions. In
the event of any dividend or other distribution (whether in the form of cash, Shares, other securities, or other property), reorganization, merger, consolidation, combination, amalgamation, repurchase, recapitalization, liquidation, dissolution, or
sale, transfer, exchange or other disposition of all or substantially all of the assets of the Company, or sale or exchange of Shares or other securities of the Company, Change in Control, issuance of warrants or other rights to purchase Shares or
other securities of the Company, other similar corporate transaction or event, other unusual or nonrecurring transaction or event affecting the Company or its financial statements or any change in any Applicable Laws or Applicable Accounting
Standards , the Administrator, on such terms and conditions as it deems appropriate, either by the terms of the Award or by action taken prior to the occurrence of such transaction or event (except that action to give effect to a change in
Applicable Law or Applicable Accounting Standards may be made within a reasonable period of time after such change) and either automatically or upon the Grantee’s request, is hereby authorized, without the Grantee’s express prior written
consent, to take any one or more of the following actions whenever the Administrator determines that such action is appropriate in order to (x) prevent dilution or enlargement of the benefits or potential benefits intended by the Company to be
made available under the Plan or with respect to any Award granted or issued under the Plan, (y) to facilitate such transaction or event or (z) give effect to such changes in Applicable Laws or Applicable Accounting Standards: 

(i) To provide for the cancellation of any such Award in exchange for either an amount of cash or other property or any combination thereof
with a value equal to the amount that could have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the Grantee’s rights under the vested portion of such Award, as applicable; provided that,
if the amount that could have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the Grantee’s rights, in any case, is equal to or less than zero, then the Award may be terminated without
payment; 
 (ii) To provide that such Award shall vest and, to the extent applicable, be exercisable as to all Shares covered
thereby, notwithstanding anything to the contrary in the Plan or the provisions of such Award; 

  
 13 













 (iii) To provide that such Award be assumed by the successor or survivor corporation, or a
parent or subsidiary thereof, or shall be substituted for by awards covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of shares and/or applicable
exercise or purchase price, in all cases, as determined by the Administrator; 
 (iv) To make adjustments in the number and type of Shares
(or other securities or property) subject to outstanding Awards and/or with respect to which Awards may be granted under the Plan (including, but not limited to, adjustments of the limitations in Article IV hereof on the maximum number and kind of
shares which may be issued) and/or in the terms and conditions of (including the grant or exercise price or applicable performance goals), and the criteria included in, outstanding Awards; 

(v) To replace such Award with other rights or property selected by the Administrator; and/or 

(vi) To provide that the Award will terminate and cannot vest, be exercised or become payable after the applicable event. 

(c) Effect of Non-Assumption in a Change in Control. Notwithstanding the provisions of
Section 10(b), if a Change in Control occurs and a Grantee’s Awards are not continued, converted, assumed, or replaced with a substantially similar award by (i) the Company, or (ii) a successor entity or its parent or subsidiary
(an “Assumption”), and provided that the Grantee is still an Employee, Director or Consultant, then, immediately prior to the Change in Control, such Awards shall become fully vested, exercisable and/or payable, as
applicable, and all forfeiture, repurchase and other restrictions on such Awards shall lapse, in which case, such Awards shall be canceled upon the consummation of the Change in Control in exchange for the right to receive the Change in Control
consideration payable to other holders of Shares (i) which may be on such terms and conditions as apply generally to holders of Shares under the Change in Control documents (including, without limitation, any escrow, earn-out or other deferred consideration provisions) or such other terms and conditions as the Administrator may provide, and (ii) determined by reference to the number of Shares subject to such Awards
and net of any applicable exercise price; provided that to the extent that any Awards constitute “nonqualified deferred compensation” that may not be paid upon the Change in Control under Section 409A without the imposition of taxes
thereon under Section 409A, the timing of such payments shall be governed by the applicable Award Agreement (subject to any deferred consideration provisions applicable under the Change in Control documents); and provided, further, that if the
amount to which a Grantee would be entitled upon the settlement or exercise of such Award at the time of the Change in Control is equal to or less than zero, then such Award may be terminated without payment. The Administrator shall determine
whether an Assumption of an Award has occurred in connection with a Change in Control. 
 (d) Definition of Assumption. For the
purposes of this Section 10, an Assumption of an Award shall be considered to have occurred in the Award is assumed or substituted for if, following the Change in Control, the Award confers the right to purchase or receive, for each Share
subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash or other securities or property) received in the transaction constituting a Change in Control by holders of Shares for each Share held on the
effective date of such transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the
transaction constituting a Change in Control is not solely common stock (or its equivalent) of the successor entity or its parent or subsidiary, the Administrator may, with the consent of the successor entity, provide that the consideration to be
received upon the exercise or vesting of an Award, for each Share subject thereto, will be solely common stock of the successor entity or its parent or subsidiary substantially equal in fair market value to the per Share consideration received by
holders of Shares in the transaction constituting a Change in Control. 

  
 14 













 (e) Administrative Stand Still. In the event of any pending stock dividend, stock
split, combination or exchange of shares, merger, consolidation or other distribution (other than normal cash dividends) of Company assets to shareholders, or any other extraordinary transaction or change affecting the Shares or the Share, including
any Equity Restructuring or any securities offering or other similar transaction, for administrative convenience, the Administrator may refuse to permit the exercise of any Award for up to sixty (60) days before or after such
transaction. 
 (f) General. Except as expressly provided in the Plan or the Administrator’s action under the Plan, no Grantee
will have any rights due to any subdivision or consolidation of Shares of any class, dividend payment, increase or decrease in the number of Shares of any class or dissolution, liquidation, merger, or consolidation of the Company or other
corporation. Except as expressly provided with respect to an Equity Restructuring under Section 10(a) or the Administrator’s action under the Plan, no issuance by the Company of Shares of any class, or securities convertible into
Shares of any class, will affect, and no adjustment will be made regarding, the number of Shares subject to an Award or the Award’s grant or exercise price. The existence of the Plan, any Award Agreements and the Awards granted hereunder will
not affect or restrict in any way the Company’s right or power to make or authorize (i) any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, (ii) any merger,
consolidation dissolution or liquidation of the Company or sale of Company assets or (iii) any sale or issuance of securities, including securities with rights superior to those of the Shares or securities convertible into or exchangeable for
Shares. The Administrator may treat Grantees and Awards (or portions thereof) differently under this Section 10. 
 11. Effective
Date and Term of Plan. The Plan shall become effective upon the Pricing Date (the “Effective Date”). The Plan shall continue in effect for a term of ten (10) years after the date of approval of the Plan by the Board,
unless sooner terminated. If the Plan is not approved by the Company’s shareholders, the Plan will not become effective, no Awards will be granted under the Plan and the Prior Plan will continue in full force and effect in accordance with its
terms. 
 12. Amendment, Suspension or Termination of the Plan and Awards. 

(a) The Board or the Company’s compensation committee may at any time amend, suspend or terminate the Plan; provided, however, that no
such amendment, suspension or termination shall be made without the approval of the Company’s shareholders to the extent such approval is required by Applicable Laws. 

(b) No Award may be granted during any suspension of the Plan or after termination of the Plan. 

(c) Unless otherwise determined by the Administrator in good faith, the suspension or termination of the Plan (including termination of the
Plan under Section 11) shall not materially adversely affect any rights under Awards already granted to a Grantee. 
 (d) The
Administrator may amend, modify or terminate any outstanding Award, including by substituting another Award of the same or a different type, changing the exercise or settlement date, and converting an Incentive Stock Option to a Non-Qualified Stock Option. The Grantee’s consent to such action will be required unless (i) the action, taking into account any related action, does not materially and adversely affect the Grantee’s
rights under the Award, or (ii) the change is permitted under Section 10. 

  
 15 













 
Notwithstanding the foregoing or anything in the Plan to the contrary, the Administrator may, without the approval of the shareholders of the Company, (i) reduce the exercise price
per share of outstanding Options or Stock Appreciation Rights or (ii) cancel outstanding Options or Stock Appreciation Rights in exchange for cash, other Awards or Options or Stock Appreciation Rights with an exercise price per share
that is less than the exercise price per share of the original Options or Stock Appreciation Rights. 
 13. No Effect on Terms of
Employment/Consulting Relationship. The Plan shall not confer upon any Grantee any right with respect to the Grantee’s Continuous Service, nor shall it interfere in any way with his or her right or the right of the Company or any Related
Entity to terminate the Grantee’s Continuous Service at any time, with or without Cause, and with or without notice. The ability of the Company or any Related Entity to terminate the employment of a Grantee who is employed at will is in no way
affected by its determination that the Grantee’s Continuous Service has been terminated for Cause for the purposes of this Plan. 
 14.
No Effect on Retirement and Other Benefit Plans. Except as specifically provided in a retirement or other benefit plan of the Company or a Related Entity, Awards shall not be deemed compensation for purposes of computing benefits or
contributions under any retirement plan of the Company or a Related Entity, and shall not affect any benefits under any other benefit plan of any kind or any benefit plan subsequently instituted under which the availability or amount of benefits is
related to level of compensation. The Plan is not a “Retirement Plan” or “Welfare Plan” under the Employee Retirement Income Security Act of 1974, as amended. 

15. Lock-Up Period . The Company may, at the request of any underwriter representative or
otherwise, in connection with registering the offering of any Company securities under the Securities Act, prohibit Grantees from, directly or indirectly, selling or otherwise transferring any Shares or other Company securities during a period of up
to one hundred eighty (180) days following the effective date of a Company registration statement filed under the Securities Act, or such longer period as determined by the underwriter. 

16. Section 409A of the U.S. Code. 

(a) General. The Company intends that all Awards granted to U.S. taxpayers be structured to comply with, or be exempt from,
Section 409A, such that no adverse tax consequences, interest, or penalties under Section 409A apply. Notwithstanding anything in the Plan or any Award Agreement to the contrary, the Administrator may, without a Grantee’s consent,
amend this Plan or Awards, adopt policies and procedures, or take any other actions (including amendments, policies, procedures and retroactive actions) as are necessary or appropriate to preserve the intended tax treatment of Awards, including any
such actions intended to (i) exempt this Plan or any Award from Section 409A, or (ii) comply with Section 409A, including regulations, guidance, compliance programs and other interpretative authority that may be issued after an
Award’s grant date. The Company makes no representations or warranties as to an Award’s tax treatment under Section 409A or otherwise. The Company will have no obligation under this Section 16 or otherwise to avoid the taxes,
penalties or interest under Section 409A with respect to any Award and will have no liability to any Grantee or any other person if any Award, compensation or other benefits under the Plan are determined to constitute noncompliant
“nonqualified deferred compensation” subject to taxes, penalties or interest under Section 409A. 
 (b) Separation from
Service. If an Award to a U.S. taxpayer constitutes “nonqualified deferred compensation” under Section 409A, any payment or settlement of such Award upon a termination of a Grantee’s Employee, Director, or Consultant
relationship will, to the extent necessary to avoid taxes under Section 409A, be made only upon the Grantee’s “separation from service” (within the meaning of Section 409A), whether such “separation from service”
occurs upon or after the termination of the Grantee’s Employee, Director, or Consultant relationship. For purposes of this Plan or any Award Agreement relating to any such payments or benefits, references to a “termination,”
“termination of employment” or like terms means a “separation from service.” 

  
 16 













 (c) Payments to Specified Employees. Notwithstanding any contrary provision in the
Plan or any Award Agreement, any payment(s) of “nonqualified deferred compensation” required to be made under an Award to a “specified employee” (as defined under Section 409A and as the Administrator determines) due to his
or her “separation from service” will, to the extent necessary to avoid taxes under Section 409A(a)(2)(B)(i) of the U.S. Code, be delayed for the six-month period immediately following such
“separation from service” (or, if earlier, until the specified employee’s death) and will instead be paid (as set forth in the Award Agreement) on the day immediately following such six-month
period or as soon as administratively practicable thereafter (without interest). Any payments of “nonqualified deferred compensation” under such Award payable more than six (6) months following the Grantee’s “separation from
service” will be paid at the time or times the payments are otherwise scheduled to be made. 
 17. Section 457A of the U.S. Code.
Notwithstanding anything herein to the contrary, no payment shall be made under any Award under the Plan that would cause the compensation payable to the Grantee under such Award to be taxable under Section 457A of the U.S. Code. 

18. Additional Terms of Incentive Stock Options. Notwithstanding anything to the contrary in the Plan, the following terms shall govern
any Incentive Stock Options granted under the Plan. The Administrator may grant Incentive Stock Options only to employees of the Company, any of its present or future parent or subsidiary corporations, as defined in Sections 424(e) or (f) of
the U.S. Code, respectively, and any other entities the employees of which are eligible to receive Incentive Stock Options under the U.S. Code. If an Incentive Stock Option is granted to a Greater Than 10% Shareholder, the exercise price will not be
less than 110% of the Fair Market Value on the Option’s grant date, and the term of the Option will not exceed five (5) years. All Incentive Stock Options will be subject to and construed consistently with Section 422 of the U.S.
Code. By accepting an Incentive Stock Option, the Grantee agrees to give prompt notice to the Company of dispositions or other transfers (other than in connection with a Change in Control) of Shares acquired under the Option made within (aa) two
(2) years from the grant date of the Option or (b) one year after the transfer of such Shares to the Grantee, specifying the date of the disposition or other transfer and the amount the Grantee realized, in cash, other property, assumption
of indebtedness or other consideration, in such disposition or other transfer. Neither the Company nor the Administrator will be liable to a Grantee, or any other party, if an Incentive Stock Option fails or ceases to qualify as an “incentive
stock option” under Section 422 of the U.S. Code. Any Incentive Stock Option or portion thereof that fails to qualify as an “incentive stock option” under Section 422 of the U.S. Code for any reason, including becoming
exercisable with respect to Shares having a Fair Market Value exceeding the $100,000 limitation under U.S. Treasury Regulation Section 1.422-4, will be a
Non-Qualified Stock Option. An Incentive Stock Option shall not be transferable other than by will and by the laws of descent and distribution and, during the lifetime of the Grantee, may only be exercised by
the Grantee. 
 19. Data Privacy. As a condition for receiving any Award, each Grantee explicitly and unambiguously consents to the
collection, use and transfer, in electronic or other form, of personal data as described in this section by and among the Company and its Related Parties exclusively for implementing, administering and managing the Grantee’s participation in
the Plan. The Company and its Related Parties may hold certain personal information about a Grantee, including the Grantee’s name, address and telephone number; birthdate; social security, insurance number or other identification number;
salary; nationality; job title(s); any Shares held in the Company or its Related Parties; and Award details, to implement, manage and administer the Plan and Awards (the “Data”). The Company and its Related Parties may
transfer the Data amongst themselves as necessary to implement, administer and manage a Grantee’s participation in the Plan, and the Company and its Related Parties may transfer the Data to third parties assisting the Company with Plan
implementation, administration and management. These recipients may 

  
 17 













 
be located in the Grantee’s country, or elsewhere, and the Grantee’s country may have different data privacy laws and protections than the recipients’ country. By accepting an
Award, each Grantee authorizes such recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, to implement, administer and manage the Grantee’s participation in the Plan, including any required Data
transfer to a broker or other third party with whom the Company or the Grantee may elect to deposit any Shares. The Data related to a Grantee will be held only as long as necessary to implement, administer, and manage the Grantee’s
participation in the Plan. A Grantee may, at any time, view the Data that the Company holds regarding such Grantee, request additional information about the storage and processing of the Data regarding such Grantee, recommend any necessary
corrections to the Data regarding the Grantee or refuse or withdraw the consents in this Section 19 in writing, without cost, by contacting the local human resources representative. If the Grantee refuses or withdraws the consents in this
Section 19, the Company may cancel Grantee’s ability to participate in the Plan and, in the Administrator’s discretion, the Grantee may forfeit any outstanding Awards. For more information on the consequences of refusing or
withdrawing consent, Grantees may contact their local human resources representative. 
 20. Claw-back Provisions. All Awards
(including, without limitation, any proceeds, gains or other economic benefit actually or constructively received by the Grantee upon any receipt or exercise of any Award or upon the receipt or resale of any Shares underlying the Award) shall be
subject to the provisions of any claw-back policy implemented by the Company, including, without limitation, any claw-back policy adopted to comply with Applicable Laws (including the U.S. Dodd-Frank Wall Street Reform and Consumer Protection Act
and any rules or regulations promulgated thereunder) as and to the extent set forth in such claw-back policy or the Award Agreement. 
 21.
Unfunded Obligation. Any amounts payable to Grantees pursuant to the Plan shall be unfunded and unsecured obligations for all purposes. Neither the Company nor any Related Entity shall be required to segregate any monies from its general
funds, or to create any trusts, or establish any special accounts with respect to such obligations. The Company shall retain at all times beneficial ownership of any investments, including trust investments, which the Company may make to fulfill its
payment obligations hereunder. Any investments or the creation or maintenance of any trust or any Grantee account shall not create or constitute a trust or fiduciary relationship between the Administrator, the Company or any Related Entity and a
Grantee, or otherwise create any vested or beneficial interest in any Grantee or the Grantee’s creditors in any assets of the Company or a Related Entity. The Grantees shall have no claim against the Company or any Related Entity for any
changes in the value of any assets that may be invested or reinvested by the Company with respect to the Plan. 
 22. Entire Plan.
This Plan, the individual Award Agreements and notices of issuance of the Awards, together with all the exhibits hereto and thereto, constitute and contain the entire stock incentive plan and understanding of the parties with respect to the subject
matter hereof and supersedes any and all prior negotiations, correspondence, agreements, understandings, memorandum, duties or obligations between the parties respecting the subject matter hereof. If any contradiction occurs between the Plan and any
Award Agreement or other written agreement between a Grantee and the Company (or any Subsidiary) that the Administrator has approved, the Plan will govern, unless it is expressly specified in such Award Agreement or other written document that a
specific provision of the Plan will not apply. 
 23. Construction. Captions and titles contained herein are for convenience only and
shall not affect the meaning or interpretation of any provision of the Plan. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is not
intended to be exclusive, unless the context clearly requires otherwise. 

  
 18 













 24. Broker-Assisted Sales. In the event of a broker-assisted sale of Shares in
connection with the payment of amounts owed by a Grantee under or with respect to the Plan or Awards: (a) any Shares to be sold through the broker-assisted sale will be sold on the day the payment first becomes due, or as soon thereafter as
practicable; (b) such Shares may be sold as part of a block trade with other Grantees in the Plan in which all participants receive an average price; (c) the applicable Grantee will be responsible for all broker’s fees and other costs
of sale, and by accepting an Award, each Grantee agrees to indemnify and hold the Company harmless from any losses, costs, damages, or expenses relating to any such sale; (d) to the extent the Company or its designee receives proceeds of such
sale that exceed the amount owed, the Company will pay such excess in cash to the applicable Grantee as soon as reasonably practicable; (e) the Company and its designees are under no obligation to arrange for such sale at any particular price;
and (f) in the event the proceeds of such sale are insufficient to satisfy the Grantee’s applicable obligation, the Grantee may be required to pay immediately upon demand to the Company or its designee an amount in cash sufficient to
satisfy any remaining portion of the Grantee’s obligation.  
 25. Plan Language. The official language of the Plan shall
be English. To the extent that the Plan or any Award Agreements are translated from English into another language, the English version of the Plan and Award Agreements will always govern, in the event that there are inconsistencies or ambiguities
which may arise due to such translation. 
 26. Applicable Currency. The Award Agreement shall specify the currency applicable to such
Award. The Administrator may determine, in its sole discretion, that an Award denominated in one currency may be paid in any other currency based on the prevailing exchange rate as the Administrator deems appropriate. A Grantee may be required to
provide evidence that any currency used to pay the exercise price of any Award were acquired and taken out of the jurisdiction in which the Grantee resides in accordance with Applicable Laws, including foreign exchange control laws and regulations.
In the absence of a designation in an Award Agreement, the currency applicable to an Award shall be U.S. Dollars. 
 27. Conformity to
Securities Laws. The Plan is intended to conform to the extent necessary with Applicable Laws. Notwithstanding anything herein to the contrary, the Plan and all Awards will be administered only in conformance with Applicable Laws.
Notwithstanding anything herein to the contrary, the Plan and all Awards will be administered only in conformance with Applicable Laws. To the extent Applicable Laws permit, the Plan and all Award Agreements will be deemed amended as necessary to
conform to Applicable Laws. 
 28. Governing Law. The Plan and all Awards will be governed by and interpreted in accordance with the
laws of the Cayman Islands, without regard to conflicts of laws thereof.  
 29. Severability. If any portion of the Plan or
any action taken under it is held illegal or invalid for any reason, the illegality or invalidity will not affect the remaining parts of the Plan, and the Plan 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. 
 30. Electronic Forms. To the extent permitted by Applicable Law and in the
discretion of the Administrator, a Grantee may submit any form or notice as set forth herein by means of an electronic form approved by the Administrator.

 EXHIBIT A 

STOCK OPTION AWARD 

AGREEMENT 
 1.
Grant of Option. Connect Biopharma Holdings Limited, an exempted company incorporated with limited liability under the laws of the Cayman Islands (the “Company”), hereby grants to the Grantee, an option (the
“Option”) to purchase the Total Number of Ordinary Shares subject to the Option (the “Shares”) set forth in the Notice of Stock Option Award (the “Notice”), at the Exercise
Price per Share set forth in the Notice (the “Exercise Price”) subject to the terms and provisions of the Notice, this Stock Option Award Agreement (the “Option Agreement”) and the
Company’s 2021 Stock Incentive Plan, as amended from time to time (the “Plan”), which are incorporated herein by reference. The Grantee’s acceptance of the Option and participation in the Plan are voluntary. Other
than with respect to the use of a defined term that is defined in this Agreement, in the event of any inconsistency between the Plan and this Option Agreement, the terms of the Plan will control. Unless otherwise defined herein, the terms used
herein shall have the same meanings ascribed to them in the Plan or the Notice.  
 2. Exercise of Option. 

(a) Right to Exercise. The Option may not be exercised until vested. Subject to Section 5, the Option shall be exercisable before
Expiration Date in accordance with the Vesting Schedule set out in the Notice and pursuant to the applicable provisions of the Plan and this Option Agreement. The Grantee shall be subject to reasonable limitations on the number of requested
exercises during any monthly or weekly period as determined by the Administrator. In no event shall the Company issue fractional Shares. Notwithstanding anything in the Notice, the Plan or this Option Agreement to the contrary, unless the
Administrator otherwise determines, the Option will immediately expire and be forfeited as to any portion that is not vested and exercisable as of the date of Grantee’s termination of Continuous Service for any reason (after taking into
consideration any accelerated vesting and exercisability which may occur in connection with such termination). 
 (b) Method of
Exercise. The Grantee may exercise the Option by delivery of an exercise notice (in the form attached to the Notice as Exhibit B or such other form designated by the Administrator for such purpose) stating the election to exercise the
Option, the whole number of Shares in respect of which the Option is being exercised and such other provisions as may be required by the Administrator, accompanied by payment of the Exercise Price, or by such other procedure as specified from time
to time by the Administrator. The exercise notice shall be delivered to the Company in person, by certified mail, or by such other method (including electronic transmission) as determined from time to time by the Administrator, accompanied by
payment of the Exercise Price. The Option shall be deemed to be exercised upon receipt by the Company of such notice accompanied by the payment of the Exercise Price and any applicable tax withholding, which shall be deemed to be satisfied in
accordance with Section 2(c) below. 
 (c) Taxes; Tax Withholding. Notwithstanding any other provision of this Option Agreement:

 (i) Regardless of any action the Company, any Related Entity or the 

  
 22 













 
Grantee’s employing company, if different (the “Employer,” and, collectively, the “Company Group”) takes with respect to any or all Tax
Obligations (as defined below), the Grantee understands that the Grantee (and not the Company) shall be responsible for any Tax Obligations, which may exceed the amount actually withheld by the Company Group. The Grantee agrees to indemnify and keep
indemnified the Company Group from and against any such Tax Obligations 
 (ii) No Shares will be delivered to the Grantee or other Person
pursuant to the exercise of the Option until the Grantee or other Person has made arrangements acceptable to the Administrator for the satisfaction of applicable Tax Obligations resulting from the grant, vesting or exercise of the Option, the
distribution of the Shares issuable with respect thereto, or any other taxable event related to the Option. The Grantee acknowledges that if the Grantee is subject to Tax Obligations in more than one jurisdiction, the Company Group may be required
to withhold or account for Tax Obligations in more than one jurisdiction. The Grantee agrees to pay the Company Group any Tax Obligations that cannot be satisfied by the means described in this Section 2(c). 

(iii) The Grantee specifically authorizes the Company Group, or their respective agents, to satisfy the Grantee’s obligations in regards
to any Tax Obligations through the withholding by the Company Group or their respective agents from any wages or other compensation paid or payable to the Grantee an amount sufficient to satisfy such Tax Obligations. Subject to Section 7(c) of
the Plan, the Tax Obligations may be satisfied in any form of consideration permitted by the Administrator for the payment of the Exercise Price pursuant to Section 3 below. Upon exercise of the Option, the Company or the Grantee’s
employer shall have the right to offset or withhold (from any amount owed by the Company or the Grantee’s employer to the Grantee) or collect from the Grantee or other Person an amount sufficient to satisfy such Tax Obligations. 

(iv) For purposes of this Option Agreement, “Tax Obligations” shall mean (A) all withholding or other taxes
applicable to the Grantee’s taxable income in whatever jurisdiction, plus (B) if permitted under the laws of the jurisdiction in which the Grantee resides, any liability of the Company Group for income tax, withholding tax, wage tax,
solidarity surcharge, and any other employment related taxes or social insurance contributions in any jurisdiction, in each case resulting from the grant, vesting or exercise of the Option, the acquisition of Shares by the Grantee, the disposal of
any Shares, or otherwise pursuant to this Option Agreement, or any other taxable event related to the Option. In the absence of a contrary determination by the Company (or, with respect to withholding pursuant to withholding pursuant to
Section 3(c) below if the Grantee is a Section 16 Person, a contrary determination by the Administrator), all tax withholding obligations will be calculated based on the maximum applicable statutory withholding rates. 

(v) Subject to Section 7(c) of the Plan, in the absence of a contrary determination by the Company (or, with respect to withholding
pursuant to withholding pursuant to Section 3(c) below if the Grantee is a Section 16 Person, a contrary determination by the Administrator), all tax withholding obligations will be calculated based on the maximum applicable statutory
withholding rates. In the event of over-withholding, the Grantee may receive a refund of any over-withheld amount in cash and (with no entitlement to the equivalent in Shares) or if not refunded, the Grantee may seek a refund from the local tax
authorities. In the event of under-withholding, the Grantee may be required to pay any additional Tax Obligations directly to the applicable tax authority or to the Company Group. The satisfaction of any Tax Obligations pursuant to Section 3(c)
below shall be subject to any limitations set forth in Section 7(c) of the Plan to the extent required to avoid the liability classification of the applicable award under generally accepted accounting principles in the United States of America.


  
 23 













 (vi) The Grantee acknowledges that the Grantee is ultimately liable and responsible for all
Tax Obligations in connection with the Option, regardless of any action the Company Group takes with respect to any Tax Obligations that arise in connection with the Option. Neither the Company nor any member of the Company Group makes any
representation or undertaking regarding the tax treatment to the Grantee in connection with the awarding, vesting or exercise of the Option or the subsequent sale of Shares. The Company Group does not commit and are under no obligation to structure
the Option to reduce or eliminate the Grantee’s tax liability. 
 (d) Other Agreements. As a condition to the exercise of the
Option, the Grantee shall execute, acknowledge and agree to be bound by the provisions of that the Shareholders Agreement (if any). The Grantee acknowledges and agrees that the Award and any Shares issued pursuant thereto shall be subject to the
M&A. 
 (e) Payment Upon Exercise. This grant of Options does not provide any right for the Grantee to receive a cash payment, and
only shares of Common Stock will be issued upon exercise of the Options. Notwithstanding anything in the Plan or this Option Agreement herein to the contrary, no payment shall be made under this Option that would cause the compensation payable to
the Grantee under this Option to be taxable under Section 457A of the U.S. Code. Additionally, in the discretion of the Administrator, American depositary shares in an amount equal to the number of Shares which otherwise would be distributed
pursuant to this Option may be distributed in lieu of Shares in settlement of the Option. If the number of Shares represented by an American depositary share is other than on a
one-to-one basis, the provisions of this Option and the Option Agreement shall be adjusted to reflect the distribution of American depositary shares in lieu of Shares.

 3. Method of Payment. Payment of the Exercise Price shall be made by any of the following, or a combination thereof, at the
election of the Grantee and as determined by the Administrator; provided, however, that such exercise method does not then violate any Applicable Law or the Plan, provided further, that the portion of the Exercise Price equal to the par value of the
Shares must be paid as legal consideration: 
 (a) cash; 

(b) check; 
 (c) to the extent
permitted by the Administrator, surrender of Shares (including vested Shares issuable upon exercise of the Option) or delivery of a properly executed form of attestation of ownership of Shares as the Administrator may require which have a Fair
Market Value on the date of surrender or attestation equal to the aggregate Exercise Price of the Shares as to which the Option is being exercised; 

  
 24 













 (d) payment through a broker-dealer sale and remittance procedure pursuant to which the
Grantee (i) shall provide written instructions to a Company-designated brokerage firm to effect the immediate sale of some or all of the purchased Shares and remit to the Company sufficient funds to cover the aggregate exercise price payable
for the purchased Shares and (ii) shall provide written directives to the Company to deliver the certificates for the purchased Shares directly to such brokerage firm in order to complete the sale transaction; or 

(e) to the extent permitted by the Administrator, any other form of legal consideration permitted under the Plan. 

4. Restrictions on Exercise. 

(a) Notwithstanding other provisions of this Option Agreement, (i) the Option shall not be exercised if the Administrator determines that
the issuance of the Shares upon such exercise would violate any Applicable Laws, (ii) the Option shall not be exercised by the Grantee until all approvals, consents, registrations, filings or waivers which are required to be obtained by such
Grantee under Applicable Laws in connection with his/her ownership of the Shares have been duly obtained (in particular, in case that the Grantee is a PRC resident, the Grantee shall complete individual foreign exchange registration with the State
Administration of Foreign Exchange or its local branch before exercise of the Option), and (iii) if requested by the Administrator, the exercise of Option shall be conditioned upon the issuance of an opinion of a qualified counsel satisfactory
to the Administrator stating to the effect that the issuance of the Shares to the Grantee would be in full compliance with the Applicable Laws. 

(b) Notwithstanding anything provided to the contrary hereof, if the exercise of the Option within the applicable time periods set forth in
Section 5 of this Option Agreement would violate any Applicable Laws or, in case that the Grantee is a PRC resident, is prevented by clause (ii) of Section 4(a) above, the Option shall remain exercisable until three (3) months
after the date the Option first becomes exercisable, except as otherwise determined by the Administrator, but in any event no later than the Expiration Date set forth in the Notice. 

(c) The Grantee acknowledges and agrees that until the Shares are issued (as evidenced by the appropriate entry in the register of members of
the Company for the issuance of the Shares), no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Shares, notwithstanding the vesting or the exercise of the Option. After the Option is duly
exercised in accordance with the Option Agreement, the Notice and the Plan, the Company shall update (or cause to be updated) its register of members to reflect the issuance of the Shares promptly. The Grantee further acknowledges and agrees that,
upon due exercise of the Option (and registration of the issuance of the Shares in the register of members of the Company), the rights and obligations on the Shares shall be subject to the provisions of this Option Agreement, the Shareholders
Agreement (if any), the currently effective M&A, and other documents of the Company in relation to the Shares (if any), as if the Grantee is a holder of Ordinary Shares thereunder. 

5. Expiration of Option. The Option may not be exercised to any extent by anyone after, and will expire on, the first of the following
to occur: 
 (a) The Expiration Date set forth in the Notice; 

(b) If this Option is designated as an Incentive Stock Option and the Grantee, at the time the Option was granted, was a Greater Than 10%
Shareholder, the expiration of five (5) years from the Grant Date; 

  
 25 













 (c) Except as the Administrator may otherwise approve, the expiration of twelve
(12) months following the date of the Grantee’s termination of Continuous Service for any reason other than death, Disability or a termination for Cause; 

(d) Except as the Administrator may otherwise approve, the expiration of twelve (12) months following the date of the Grantee’s
termination of Continuous Service by reason of Grantee’s Disability; 
 (e) Except as the Administrator may otherwise approve, the
expiration of twelve (12) months following the date of Grantee’s termination of Continuous Service by reason of Grantee’s death (or, in the event of Grantee’s death within three (3) months following Grantee’s
termination of Continuous Service, twelve (12) months following the date of death); and 
 (f) Except as the Administrator may otherwise
approve, the date of the termination of the Grantee’s Continuous Service for Cause. 
 6. Transferability of Option. 

(a) Option Generally Non-Transferable. The Option (and the rights conferred hereby) may not be
transferred or disposed of in any manner other than by will or by the laws of descent and distribution, provided, however, that the Option (to the extent the Option is a Non-Qualified Option) may be
transferred during the lifetime of the Grantee only as permitted by Applicable Law and to the extent and in the manner authorized by the Administrator, and at the price and on the conditions not objected by the Administrator. Notwithstanding the
foregoing, the Grantee may designate one or more beneficiaries of the Grantee’s Option in the event of the Grantee’s death on a beneficiary designation form provided by the Administrator. Following the death of the Grantee, the Option, to
the extent provided in Section 5, may be exercised (a) by the Person or Persons designated under the deceased Grantee’s beneficiary designation or (b) in the absence of an effectively designated beneficiary, by the Grantee’s
legal representative or by any Person empowered to do so under the deceased Grantee’s will or under the then Applicable Laws of descent and distribution. The terms of the Option shall be binding upon the executors, administrators, heirs,
successors and transferees of the Grantee. 
 (b) Stop-Transfer Notices. In order to ensure compliance with the restrictions on
transfer set forth in this Option Agreement, the Notice, the Plan, the Shareholders Agreement and the M&A, the Company may issue appropriate “stop transfer” instructions to its transfer agent, and, if the Company transfers its own
securities, it may make appropriate notations to the same effect in its own records. 
 (c) Refusal to Transfer. The Company shall not
be required to (i) record on its register of members any transfer of Shares in violation of any of the provisions of this Option Agreement, the Shareholders Agreement or the M&A, or (ii) treat as owner of such Shares or to accord the
right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so sold or transferred in violation of any of the provisions of this Option Agreement, the Shareholders Agreement or the M&A. 

7. Tax Consequences. THE GRANTEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THE OPTION OR DISPOSING OF THE SHARES.


  
 26 













 
THE GRANTEE REPRESENTS TO THE COMPANY THAT THE GRANTEE HAS REVIEWED WITH THE GRANTEE’S OWN TAX ADVISORS THE TAX CONSEQUENCES OF THIS OPTION AND THE TRANSACTIONS CONTEMPLATED BY THE GRANT
NOTICE AND THIS OPTION AGREEMENT. THE GRANTEE IS RELYING SOLELY ON SUCH ADVISORS AND NOT ON ANY STATEMENTS OR REPRESENTATIONS OF THE COMPANY AND/OR THE TRUSTEE OR ANY OF THEIR AGENTS. 

8. Adjustments Upon Changes in Capitalization. The Option shall be entitled to adjustment upon changes in capitalization of the Company
pursuant to Section 10 of the Plan. 
 9. Lock-Up Agreement. 

(a) Agreement. The Grantee, if requested by the Company and the lead underwriter of any public offering of the Ordinary Shares (the
“Lead Underwriter”), hereby irrevocably agrees not to sell, contract to sell, grant any option to purchase, transfer the economic risk of ownership in, make any short sale of, pledge or otherwise transfer or dispose of any
interest in any Ordinary Shares or any securities convertible into or exchangeable or exercisable for or any other rights to purchase or acquire Ordinary Shares (except Ordinary Shares included in such public offering or acquired on the public
market after such offering) during the 180-day period following the effective date of a registration statement of the Company filed under the Securities Act of 1933, as amended, or such shorter or longer
period of time as the Lead Underwriter shall specify. 
 (b) Additional Obligations. The Grantee further agrees to sign such documents
as may be requested by the Lead Underwriter to effect the foregoing and agrees that the Company may impose stop-transfer instructions with respect to such Ordinary Shares subject to the lock-up period until
the end of such period. The Company and the Grantee acknowledge that each Lead Underwriter of a public offering of the Company’s stock, during the period of such offering and for the lock-up period
thereafter, is an intended beneficiary of this Section. 
 (c) No Amendment Without Consent of Lead Underwriter. During the period
from identification of a Lead Underwriter in connection with any public offering of the Company’s Ordinary Shares until the earlier of (i) the expiration of the lock-up period specified in subsection
(a) in connection with such offering or (ii) the abandonment of such offering by the Company and the Lead Underwriter, the provisions of this Section may not be amended or waived except with the consent of the Lead Underwriter. 

10. Power of Attorney. The Grantee hereby grants a power of attorney to the Board or any Person designated by the Board to
(a) exercise the voting rights (if any) with respect to the Shares (including executing any shareholders’ resolutions), and (b) execute, deliver and perform, on behalf of the Grantee, any share purchase agreement, share subscription
agreement, shareholders agreement, and any other similar agreements and documents (including any documents, instruments and certificates contemplated in the aforesaid agreements and documents, and any amendments, restatements or supplements to the
aforesaid agreements and documents from time to time), which are required to be signed by the Grantee due to the fact that the Grantee is a holder of Shares, in the future equity financing or financing transaction of the Company or otherwise. 

  
 27

invalid, illegal or unenforceable in any aspect in accordance with any Applicable Laws, such provisions shall be enforced to the fullest extent allowed by the Applicable Law, and the validity, legality or enforceability of the remaining provisions
of the Notice, the Plan or this Option Agreement shall not be affected or compromised in any aspect. The parties shall negotiate in good faith to replace such invalid, illegal or unenforceable provisions with effective provisions that accomplish to
the greatest extent permitted by law and the intentions of the parties, and the economic effect of such effective provisions shall be as close as possible to the economic effect of those invalid, illegal or unenforceable provisions.

the Notice and this Option Agreement. The resolution of such question or dispute by the Administrator shall be final and binding on all Persons. 

16. Venue and Waiver of Jury Trial. The Company, the Grantee, and the Grantee’s assignees pursuant to Section 6 hereby
irrevocably and unconditionally (a) agree that any suit, action, or proceeding arising out of or in relation to this Option Agreement, the Notice, and the Plan shall be brought in Hong Kong, and (b) submit to the exclusive jurisdiction of

appoints [ * ] (address: [Hong Kong address], fax No.: +852 [ ], marked for the attention of [name of recipient]) as its agent to receive and acknowledge on his/her behalf service of any writ, summons, order, judgment or other notice of legal
process in Hong Kong. Any such legal process shall be sufficiently served on him/her if delivered to such service agent. 
 18. No Third

Company’s personnel records, or to such other address as such party may designate in writing from time to time to the other party. 

20. Conformity to Securities Laws. The Grantee acknowledges that the Plan, the Notice and this Option Agreement are intended to conform

this Option Agreement will inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth in this Option Agreement or the Plan, this Option Agreement will be binding upon and inure to the benefit
of the heirs, legatees, legal representatives, successors and assigns of the parties hereto. 
 22. Limitations Applicable to
Section 16 Persons. Notwithstanding any other provision of the Plan or this Option Agreement, if the Grantee is subject to Section 16 of the Exchange Act, the Plan, the Notice, this Option Agreement and the Option will be
subject to any additional limitations set forth in any applicable exemptive rule under Section 16 of the Exchange Act (including any amendment to Rule 16b-3) that are requirements for the application of
such exemptive rule. To the extent Applicable Laws permit, this Option Agreement will be deemed amended as necessary to conform to such applicable exemptive rule. 

23. Limitation on Grantee’s Rights. Participation in the Plan confers no rights or interests other than as herein provided. This
Option Agreement creates only a contractual obligation on the part of the Company as to amounts payable and may not be construed as creating a trust. Neither the Plan nor any underlying program, in and of itself, has any assets. The Grantee will
have only the rights of a general unsecured creditor of the Company with respect to amounts credited and benefits payable, if any, with respect to the Option, and rights no greater than the right to receive the Shares as a general unsecured creditor
with respect to the Option, as and when exercised pursuant to the terms hereof. 

  
 29 













 24. Incentive Stock Options. 

(a) If the Option is designated as an Incentive Stock Option, notwithstanding anything to the contrary in the Plan or this Option Agreement,
the following terms shall govern this Option to the extent it is designated as an Incentive Stock Option. The Administrator may grant Incentive Stock Options only to employees of the Company, any of its present or future parent or subsidiary
corporations, as defined in Sections 424(e) or (f) of the U.S. Code, respectively, and any other entities the employees of which are eligible to receive Incentive Stock Options under the U.S. Code. If an Incentive Stock Option is granted to a
Greater Than 10% Shareholder, the exercise price will not be less than 110% of the Fair Market Value on the Grant Date, and the term of the Option will not exceed five (5) years from the Grant Date. All Incentive Stock Options will be subject
to and construed consistently with Section 422 of the U.S. Code. The Grantee acknowledges that amendments or modifications made to the Option pursuant to the Plan that would cause the Option to become a
Non-Qualified Stock Option will not materially or adversely affect the Grantee’s rights under the Option, and that any such amendment or modification shall not require the Grantee’s consent. 

(b) The Grantee acknowledges that to the extent the aggregate fair market value of shares (determined as of the time the option with respect to
the shares is granted) with respect to which stock options intended to qualify as “incentive stock options” under Section 422 of the Code, including the Option, are exercisable for the first time by the Grantee during any calendar
year exceeds $100,000 or if for any other reason such stock options do not qualify or cease to qualify for treatment as “incentive stock options” under Section 422 of the Code, such stock options (including the Option) will be treated
as non-qualified stock options. The Grantee further acknowledges that the rule set forth in the preceding sentence will be applied by taking the Option and other stock options into account in the order in
which they were granted, as determined under Section 422(d) of the Code. The Grantee also acknowledges that if the Option is exercised more than three months after the Grantee’s termination of Continuous Service, other than by reason of
death or Disability, the Option will be taxed as a Non-Qualified Stock Option. 
 (c) The Grantee
will give prompt written notice to the Company of any disposition or other transfer of any Shares acquired under this Option Agreement if such disposition or other transfer is made (i) within two years from the Grant Date or (ii) within
one year after the transfer of such Shares to the Grantee. Such notice will specify the date of such disposition or other transfer and the amount realized, in cash, other property, assumption of indebtedness or other consideration, by the Grantee in
such disposition or other transfer. 
 25. ACKNOWLEDGMENT. THE GRANTEE ACKNOWLEDGES AND AGREES THAT THE OPTION SHALL VEST, IF AT ALL,
ONLY DURING THE PERIOD OF THE GRANTEE’S CONTINUOUS SERVICE (NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THE OPTION OR ACQUIRING SHARES HEREUNDER). THE GRANTEE FURTHER ACKNOWLEDGES AND AGREES THAT NOTHING IN THIS NOTICE, THE OPTION
AGREEMENT, OR THE PLAN SHALL CONFER UPON THE GRANTEE ANY RIGHT WITH RESPECT TO FUTURE AWARDS OR CONTINUATION OF THE GRANTEE’S CONTINUOUS SERVICE, NOR SHALL IT INTERFERE IN ANY WAY WITH THE GRANTEE’S RIGHT OR THE RIGHT OF THE COMPANY OR
RELATED ENTITY TO WHICH THE GRANTEE PROVIDES SERVICES TO TERMINATE THE GRANTEE’S CONTINUOUS SERVICE, WITH OR WITHOUT CAUSE, AND WITH OR WITHOUT NOTICE. THE GRANTEE ACKNOWLEDGES THAT UNLESS THE GRANTEE HAS A WRITTEN EMPLOYMENT AGREEMENT WITH THE
COMPANY TO THE CONTRARY, THE GRANTEE’S EMPLOYMENT IS AT WILL. 

  
 30 













 26. Counterparts. The Notice may be executed in one or more counterparts, including
by way of any electronic signature, subject to Applicable Law, each of which will be deemed an original and all of which together will constitute one instrument. 

27. Paperless Administration. By accepting this Award, the Grantee hereby agrees to receive documentation related to the Award by
electronic delivery, such as a system using an internet website or interactive voice response, maintained by the Company or a third party designated by the Company. 

28. Language. The Grantee acknowledges that the Grantee is proficient in the English language and understands the provisions in this
Option Agreement and the Plan or has had the ability to consult with an advisor who is sufficiently proficient in the English language, as to allow the Grantee to understand the terms of this Option Agreement and any other documents related to the
Option. Further, if the Grantee has received this Option Agreement or any other document related to 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. 
 29. Applicable Currency. The currency applicable to the Option shall be U.S. Dollars. The
Administrator may determine, in its sole discretion, that the Option may be paid in any other currency based on the prevailing exchange rate as the Administrator deems appropriate. The Grantee may be required to provide evidence that any currency
used to pay the exercise price of the Option or any Tax Obligations were acquired and taken out of the jurisdiction in which the Grantee resides in accordance with Applicable Laws, including foreign exchange control laws and regulations. 

30. Appendix. Notwithstanding any provisions in this Option Agreement, the Option shall be subject to any additional terms and
conditions for the Grantee’s country set forth in the Appendix attached hereto. Moreover, if the Grantee relocates to one of the countries included in the Appendix, the additional terms and conditions for such country, if any, will apply to the
Grantee, 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 Option Agreement.

 APPENDIX TO THE 

CONNECT BIOPHARMA HOLDINGS LIMITED 

2021 STOCK INCENTIVE PLAN 

STOCK OPTION AGREEMENT 

FOR PARTICIPANTS OUTSIDE OF THE UNITED STATES 

This Appendix includes additional terms and conditions applicable to the Grantees who provide services to the Company Group in the countries
identified below. These terms and conditions are in addition to those set forth in the Notice and Option Agreement and to the extent there are any inconsistencies between these terms and conditions and those set forth in the Notice or the Option
Agreement, these terms and conditions shall prevail. Any capitalized term used in this Appendix without definition shall have the meaning ascribed to such term in the Plan, the Notice or the Option Agreement, as applicable. This Appendix forms part
of the Option Agreement. 
 If the Grantee is a citizen or resident of a country other than the one in which the Grantee is currently
residing and/or working, transfers employment and/or residency to another country after the Grant Date, or is considered a resident of another country for local law purposes, the Company shall, in its discretion, determine to what extent the terms
and conditions contained herein shall be applicable to the Grantee. 
 For the Grantee’s convenience and information, the Company has
provided certain general information regarding some of the tax and/or exchange control requirements that may apply to the Grantee in certain of the countries identified below. The Company undertakes no obligation to update any such information and
does not ensure that it is complete or correct. As a result, the Company strongly recommends that the Grantee not rely on the information in this Appendix as the only source of information relating to the consequences of the Grantee’s
participation in the Plan because the information may be out of date at the time the Grantee exercises the Option and acquires Shares or sells Shares acquired under the Plan. The absence of any information on tax or foreign exchange requirements for
any particular country should not be regarded as an indication that no such requirements apply in that country. The laws, rules and regulations of any country regarding the holding of securities may be subject to frequent change. 

The Grantee is advised to seek appropriate professional advice as to how the relevant exchange control and tax laws in the Grantee’s
country may apply to the Grantee’s individual situation. 
 GLOBAL PROVISIONS 

1. Termination of Service. For purposes of the Option, a termination of Continuous Service will be deemed to have occurred as of the
date the Grantee is no longer actively providing services to the Company Group (regardless of the reason for such termination of Continuous Service and whether or not later found to be invalid or in breach of employment laws in the
jurisdiction where the Grantee is employed or otherwise rendering services, or the terms of the Grantee’s employment or other service agreement, if any). The Grantee’s employment or service relationship will not be extended by any notice
period (e.g., the Grantee’s period of service will 

  
 APPENDIX A-1 













 
not be extended by any contractual notice period or period of “garden leave” or similar period mandated under employment laws in the jurisdiction where the Grantee is employed or
otherwise rendering services, or the terms of the Grantee’s employment or other service agreement, if any). Unless otherwise expressly provided in the Plan or determined by the Company (a) the Grantee’s right to vest in the Option, if
any, will terminate as of the date of termination of Continuous Service, and (b) the period (if any) during which the Option may be exercised after a termination of Continuous Service will commence on such date. Notwithstanding the forgoing,
the Administrator shall have exclusive discretion to determine when a termination of Continuous Service has occurred for purposes of the Option (including when the Grantee’s is no longer considered to be actively providing services while on a
leave of absence). In the event of the Grantee’s leave of absence, vesting of the Option shall be governed by the Company’s leave of absence policies, as may be amended from time to time, and in accordance with Applicable Laws. 

2. Acknowledgment of Nature of Plan and Rights. In participating in the Plan, the Grantee acknowledges that: 

(a) for employment and labor law purposes, the Option and any Shares issuable upon exercise of the Option are an extraordinary item that do not
constitute wages of any kind for services of any kind rendered to the Company Group, and the award of rights is outside the scope of the Grantee’s employment or service contract, if any; 

(b) for employment and labor law purposes, the Option and any Shares issuable upon exercise of the Option are not part of normal or expected
wages or salary for any purposes, including, but not limited to, calculation of any severance, resignation, termination, redundancy, dismissal, end of service payments or entitlements, notice of termination or indemnity, compensation or damages in
lieu of such notice, bonuses, holiday pay, long-service awards, pension or retirement benefits or similar payments and in no event should be considered as compensation for, or relating in any way to, past services for the Company Group; 

(c) the Option and any Shares issuable upon exercise of the Option are not intended to be an integral component of compensation or to replace
any pension rights or compensation; 
 (d) neither the rights nor any provision of Plan or the policies adopted pursuant to the Plan confer
upon any Grantee any right with respect to service or employment or continuation of current service or employment and shall not be interpreted to form a service or employment contract or relationship with the Company Group; 

(e) the future value of the underlying Shares is unknown and cannot be predicted with certainty; 

(f) if the underlying Shares do not increase in value, the right may have no value; 

(g) if the Grantee exercises the Option and acquires Shares, the value of the Shares acquired upon purchase may increase or decrease in value,
even below the exercise price of the Option; and 

  
 APPENDIX A-2 













 (h) in consideration of the grant of the Option hereunder, no claim or entitlement to
compensation or damages arises from termination of the Option, and no claim or entitlement to compensation or damages shall arise from forfeiture of the Option resulting from termination of the Grantee’s employment by the Company Group (for any
reason whatsoever, whether with or without Cause, whether with or without prior notice, and whether or not in breach of local employment or labor laws) and the Grantee irrevocably releases the Company Group from any such claim that may arise; if,
notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen, the Grantee shall be deemed irrevocably to have waived the Grantee’s entitlement to pursue such claim. 

3. Insider Trading Restrictions/Market Abuse Laws. The Grantee may be subject to insider trading restrictions and/or
market abuse laws in applicable jurisdictions, including the United States and the Grantee’s country, if different, which may affect the Grantee’s ability to directly or indirectly, for himself or herself or for a third party, acquire or
sell, or attempt to sell, Shares during such times as such Grantee is considered to have “inside information” regarding the Company (as defined by Applicable Laws) or the trade in Shares. Any restrictions under these laws or regulations
may be separate and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. It shall be each Grantee’s responsibility to comply with any applicable restrictions, and each Grantee should speak
with a personal advisor on this matter. 
 4. Foreign Asset/Account Reporting; Exchange Controls. Each country may have certain
foreign asset and/or account reporting requirements and/or exchange controls which may affect the Grantee’s ability to purchase or hold Shares or cash received in respect of the Option (including from any dividends received or sale proceeds
arising from the sale of Shares) in a brokerage or bank account outside the Grantee’s country. The Grantee may be required to report such accounts, assets or transactions to the tax or other authorities in the Grantee’s country. The
Grantee also may be required to repatriate sale proceeds or other funds received as a result of his or her participation in the Plan to the Grantee’s country through a designated bank or broker and/or within a certain time after receipt. It
shall be the Grantee’s responsibility to be compliant with such regulations, and the Grantee should consult a personal legal advisor for any details. 

5. No Representations With Respect to Tax Qualification. Although the Company may endeavor to (a) qualify Options for
favorable tax treatment under the laws of the United States or jurisdictions outside of the United States or (b) avoid adverse tax treatment (e.g., under Section 409A of the Code), the Company makes no representation to that effect
and expressly disavows any covenant to maintain favorable or avoid unfavorable tax treatment, anything to the contrary in this Plan. The Company shall be unconstrained in its corporate activities without regard to the potential negative tax impact
on Grantees under the Plan. 
 6. Additional Restrictions. The Company reserves the right to impose other requirements on the Option
and the Shares purchased upon exercise of the Option, 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 Grantee to sign any
additional agreements or undertakings that may be necessary to accomplish the foregoing. 

  
 APPENDIX A-3 













 7. Data Privacy. As a condition for receiving any Award, each Grantee explicitly and
unambiguously consents to the collection, use and transfer, in electronic or other form, of personal data as described in this section by and among the Company and its Related Parties exclusively for implementing, administering and managing the
Grantee’s participation in the Plan. The Company and its Related Parties may hold certain personal information about a Grantee, including the Grantee’s name, address and telephone number; birthdate; social security, insurance number or
other identification number; salary; nationality; job title(s); any Shares held in the Company or its Related Parties; and Award details, to implement, manage and administer the Plan and Awards (the “Data”). The Company and
its Related Parties may transfer the Data amongst themselves as necessary to implement, administer and manage a Grantee’s participation in the Plan, and the Company and its Related Parties may transfer the Data to third parties assisting the
Company with Plan implementation, administration and management. These recipients may be located in the Grantee’s country, or elsewhere, and the Grantee’s country may have different data privacy laws and protections than the
recipients’ country. By accepting an Award, each Grantee authorizes such recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, to implement, administer and manage the Grantee’s participation in the
Plan, including any required Data transfer to a broker or other third party with whom the Company or the Grantee may elect to deposit any Shares. The Data related to a Grantee will be held only as long as necessary to implement, administer, and
manage the Grantee’s participation in the Plan. A Grantee may, at any time, view the Data that the Company holds regarding such Grantee, request additional information about the storage and processing of the Data regarding such Grantee,
recommend any necessary corrections to the Data regarding the Grantee or refuse or withdraw the consents in this Section 7 in writing, without cost, by contacting the local human resources representative. If the Grantee refuses or withdraws the
consents in this Section 7, the Company may cancel Grantee’s ability to participate in the Plan and, in the Administrator’s discretion, the Grantee may forfeit any outstanding Awards. For more information on the consequences of
refusing or withdrawing consent, Grantees may contact their local human resources representative. 
 AUSTRALIA 

1. Information on Taxable Event. The following provisions supplement the Option Agreement: 

(a) The Option will be taxable at either the point the Option is exercised or at the termination of services. The amount chargeable to tax will
be calculated as the difference between Fair Market Value of the Shares on the exercise date (or the termination date, if applicable) and the exercise price of the Option. 

(b) In accepting the Option, the Grantee acknowledges that any taxable gain at the Grant Date or termination, as appropriate, may result in an
income and Medicare tax charge arising. The Grantee acknowledges and confirms that the Grantee is responsible for reporting and paying all taxes to the local tax authorities and that this will be undertaken by the Grantee on a timely basis. 

2. Australian Offer Document. This offer of Options under the Plan is intended to comply with the provisions of the Corporations Act
2001, ASIC Regulatory Guide 49 and ASIC Class Order CO 14/1000. Additional details are set forth in the Offer Document for the offer of Options to Australian-resident employees attached hereto as Annex A. 

  
 APPENDIX A-4 













 3. Exchange Control Information. Exchange control reporting is required for cash
transactions exceeding AUD$10,000 and international fund transfers. The Australian bank assisting with the transaction will file the report. If there is no Australian bank involved in the transfer, the Grantee will be required to file the report.

 4. Payment Upon Exercise. This grant of Options does not provide any right for the Grantee to receive a cash payment, and only
shares of Common Stock will be issued upon exercise of the Options. 
 5. Tax Information. The Plan is a plan to which subdivision 83A-C of the Income Tax Assessment Act 1997 (Cth) applies (subject to conditions in the Act). 
 CANADA

 1. Termination of Service. The following provision replaces Section 1 of this Appendix: 

For purposes of this Option and any related rights or entitlements, the Grantee’s termination of Continuous Service is deemed to occur
(regardless of the reason for the termination, whether with or without Cause, whether with or without prior notice, and whether or not later found to be invalid or in breach of Applicable Laws in the jurisdiction where the Grantee is employed or
otherwise rendering services or the terms of the Grantee’s employment or service agreement, if any) on the date that is the earliest of (a) the effective termination date of the Grantee’s employment or service agreement, or
(b) the date the Grantee is no longer actively employed by or actively providing services to the Company or any of its Related Entities following the Grantee’s receipt of a notice of termination of employment or service agreement, or the
Grantee’s delivery of a notice of resignation or termination of service agreement to the Company or any of its Related Entities, in any such case regardless of (and without including) any notice of termination or resignation period or any
period of pay, indemnity, compensation or damages in lieu of such notice mandated under Applicable Laws (including, but not limited to, statutory law, regulatory law, civil law and/or common law) in the jurisdiction where the Grantee is employed or
otherwise rendering services or the terms of the Grantee’s employment or other service agreement, if any.    For greater certainty, for purposes of this Option and any related rights or entitlements, the Grantee will not be
considered to be employed by or providing services to the Company or any of its Related Entities, whether actively or otherwise, and shall not be entitled to further vesting of the Option, or any indemnity, compensation or damages in lieu thereof,
in respect of any notice of termination period required or any retroactive period during which the Grantee is deemed to be in the employ or service of the Company or any of its Related Entities, whether pursuant to Applicable Laws in the
jurisdiction where the Grantee is employed or rendering services or pursuant to a decision of a court or tribunal of competent jurisdiction. 

Notwithstanding the foregoing, if applicable employment standards legislation explicitly requires continued participation in the Plan during a
minimum statutory notice period, the Grantee acknowledges that his or her right to participate in the Plan, if any, will terminate effective as of the last day of the Grantee’s minimum statutory notice period, but the Grantee will not earn or
be entitled to pro-rata vesting if the vesting date falls after the end of the Grantee’s statutory notice period, nor will the Grantee be entitled to any compensation for lost vesting. 

  
 APPENDIX A-5 













 2. Payment Upon Exercise. This grant of Options does not provide any right for the
Grantee to receive a cash payment, and only shares of Common Stock will be issued upon exercise of the Options. 
 3. Language. The
following provisions will apply if the Grantee is a resident of Quebec. The parties acknowledge that it is their express wish that the Option Agreement, as well as all documents, notices and written communications relating directly or indirectly
hereto be drawn up in English. 
 Langue: Les parties reconnaissent avoir exigé la rédaction en
anglais de cette convention, ainsi que de tous documents, avis et communications écrites s’y rattachant, directement ou indirectement. 

4. Securities Law Information. Canadian residents are permitted to sell Shares acquired under the Plan through the designated broker
appointed under the Plan, if any, provided the sale of such Shares acquired under the Plan takes place outside Canada through the stock exchange on which the Shares are listed. 

5. Foreign Asset/Account Reporting Information. Canadian taxpayers are required to report any foreign specified property, including
Shares acquired under the Plan and rights to receive Shares (e.g., Options) on Form T1135 (Foreign Income Verification Statement) if the total cost of the foreign specified property exceeds C$100,000 at any time during the year. Options must be
reported (generally, at nil cost) if the C$100,000 cost threshold is exceeded because of other foreign specified property held by the Grantee. For Shares acquired under the Plan, cost generally is the adjusted cost basis
(“ACB”), which would ordinarily be equal the fair market value of such shares at the time of acquisition. If, however, the Grantee owns other Shares in the Company, the ACB of the Shares acquired under the Plan will need to
be averaged with the ACB of the other Shares. The statement is due at the same time as the Grantee’s annual tax return. The Grantee should consult his or her personal tax advisor to ensure compliance with applicable reporting obligations. 

UNITED KINGDOM 
 1.
Incorporation of Terms of the Plan. Notwithstanding anything in the Plan to the contrary, in the United Kingdom only Employees are eligible to be granted Options. Other persons who are not Employees are not eligible to receive Options in the
United Kingdom. This Option Agreement forms the rules of the employee share scheme applicable to United Kingdom-based Employees. All Options granted to Employees who are based in the United Kingdom will be granted on similar terms. Accordingly, all
references in the Option Agreement to the Grantee’s service, service agreement or termination of service shall be interpreted as references to the Grantee’s employment, contract of employment or termination of employment. 

2. Tax Withholding and Indemnity. This provision supplements Section 3.3 of the Option Agreement:** 

(a) If the Grantee is a resident of the United Kingdom, then the “Tax Obligations” shall also include the
Grantee’s primary (employee) national insurance contributions 

  
 APPENDIX A-6 













 
and, at the Company’s discretion, any secondary (employer) national insurance contributions of the Company Group. (or other similar obligations wherever in the world arising). The Grantee
agrees that the Grantee is liable for all Tax Obligations and hereby covenants to pay all such Tax Obligations as and when requested by the Company Group or by Her Majesty’s Revenue and Customs (“HMRC”) (or any other tax
authority or any other relevant authority). The Grantee also agrees to indemnify and keep indemnified the Company Group against any Tax Obligations that they are required to pay or withhold or have paid or will pay to HMRC (or any other tax
authority or any other relevant authority) on the Grantee’s behalf that is attributable to: (1) the grant or exercise of, or any benefit derived by the Grantee from, the Options or the Shares which are the subject of the Options;
(2) the transfer or issuance of Shares on the exercise of the Options; (3) any restrictions applicable to any Shares held by the Grantee ceasing to apply thereto; or (4) the disposal of any Shares (each, a “Taxable
Event”). 
 (b) The Options cannot be exercised until the Grantee has made such arrangements as the Company may require for the
satisfaction of any Tax Obligations that may arise in connection with the vesting and exercise of the Options and/or the acquisition of Shares by the Grantee. The Company shall not be required to issue, allot or transfer Shares until the Grantee has
satisfied this obligation. The Grantee undertakes that, upon request by the Company, the Grantee will join with his or her Employer in electing, pursuant to Section 431(1) of the Income Tax (Earnings and Pensions) Act 2003
(“ITEPA”) that, for relevant tax purposes, the market value of the Shares acquired upon exercise of the Option on any occasion will be calculated as if the Shares were not restricted and Sections 425 to 430 (inclusive) of
ITEPA are not to apply to such Shares. 
 (c) The Grantee agrees that if the Grantee does not pay or the Company Group does not withhold from
the Grantee the full amount of all Tax Obligations that the Grantee owes due to any Taxable Event within ninety (90) days after the end of the tax year in which the Taxable Event occurred, or such other period specified in
Section 222(1)(c) of ITEPA, then the amount that should have been withheld shall constitute a loan owed by the Grantee to the Employer, effective ninety (90) days after the end of the tax year in which the Taxable Event occurred. The
Grantee agrees that the loan will bear interest at the HMRC’s official rate and will be immediately due and repayable by the Grantee, and the Company and/or the Employer may recover it at any time thereafter by withholding the funds from
salary, bonus or any other funds due to the Grantee by the Employer, by withholding in Shares issued upon vesting and exercise of the Option or from the cash proceeds from the sale of Shares or by demanding cash or a cheque from the Grantee. The
Grantee also authorizes the Company to delay the issuance of any Shares to the Grantee unless and until the loan is repaid in full. 
 (d)
Notwithstanding the foregoing, if the Grantee is a director or executive officer of the Company (within the meaning of Section 13(k) of the Exchange Act), the Grantee understands that the foregoing provision will not apply. Instead, any Tax
Obligations not collected within ninety (90) days of the end of the UK tax year in which an event giving rise to the Tax Obligation occurs may constitute a benefit to the Grantee on which additional income tax and national insurance
contributions may be payable. The Grantee understands that he or she will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and for paying to the Company and/or
the Employer (as appropriate) the amount of any national insurance contributions due on this additional benefit, which can be recovered by any means set out in the Option Agreement. 

  
 APPENDIX A-7 













 ANNEX A TO THE APPENDIX TO THE 

CONNECT BIOPHARMA HOLDINGS LIMITED 

2021 STOCK INCENTIVE PLAN 

STOCK OPTION AGREEMENT 

FOR PARTICIPANTS IN AUSTRALIA 

Securities Law Notice and Australia Offer Document 

This disclosure has been prepared in connection with offers to employees in Australia under the Plan and the Option Agreement to which this
disclosure is attached. A copy of the terms of the Plan has been provided to the Grantee. It has been prepared to ensure any offer under the Plan (“Offer”) satisfies the conditions for exemptions granted by the Australian
Securities and Investments Commission (“ASIC”) under ASIC Class order 14/1000. 
 General Advice Only 

Any advice given to the Grantee in connection with the Offer is general advice only. It does not take into account the Grantee’s
objectives, financial situation and needs. No financial product advice is provided in the documentation relating to the Plan and nothing in the documentation should be taken to constitute a recommendation or statement of opinion that is intended to
influence the Grantee in making a decision to participate in the Plan. This means that the Grantee should consider obtaining his or her own financial product advice from an independent person who is licensed by the ASIC to give such advice. The
Company will make available upon the Grantee’s request the Australian dollar equivalent of the Exercise Price and the current market price of the underlying Shares subject to the Option. The Grantee can get those details by contacting the
Company at [_____]. 
 Australian Dollar Equivalents 

The Australia dollar equivalent of the Exercise Price or of the current market price of the underlying Shares subject to the Option may be
determined by reference to the daily exchange rate published by the Reserve Bank of Australia on the relevant date. Note that the exchange rate may fluctuate, and the Australian dollar equivalent of the Exercise Price on the actual exercise date
will depend on the then-current U.S. dollar/Australian dollar exchange rate. 
 By way of example (this is for illustrative purposes only
and is not a prediction of the Australian dollar equivalent of the Exercise Price or the applicable exchange rate on the actual exercise date), if as of January 1, 2021, the applicable exchange rate was A $1.00 = US $0.80 and the Exercise Price
specified was US $20.00, then the Australian dollar equivalent of the exercise price for the Shares under the Plan as of the date of this offer document would be A $25.00. 

Note this is not a prediction of the Australian dollar equivalent of the Exercise Price or the applicable exchange rate on the actual exercise
date. The exchange rate used for the sample calculation was determined by the Company as of the Grant Date for illustration purposes only. If and when the Grantee actually exercises the Option, the Shares will be purchased in U.S. dollars on the
exercise date. If the Grantee is converting between Australian dollars and U.S. dollars in connection with any option exercise, the exchange rate will generally be determined by the Grantee’s locally authorized bank making the exchange and
handling any fund transfer at the Grantee’s direction.

 Risks of Participation in the Plan 

Participation in the Plan and acquiring Shares in the Company carries inherent risks. These risks include the possibility of fluctuations (and
decrease) in the price of the Shares in relation to Company performance, as well as general market performance. The Grantee should carefully consider these risks in light of the Grantee’s investment objectives and personal circumstances. 

Statement under Section 83A-105 of the Income Tax Assessment Act 1997 (Cth) 

Subdivision 83A-C of the Income Tax Assessment Act 1997 (Cth) (the “Act”)
applies to the Plan and this Option, subject to the requirements of the Act. Broadly speaking when a participant acquires a right to Shares under the Act, his or her assessable income includes any “discount” (compared to market value)
given in relation to the right to Shares. 
 In this situation, the Grantee will not be entitled to exercise any Options if he or she is not
employed by the Company or a Related Entity. That means there is a real risk that, under the conditions of the Plan, the Grantee will forfeit or lose his or her Options (other than by disposing of them, exercising them or letting them lapse)
(“real risk of forfeiture or RROF”). Based on current Australian Tax Office guidance, the Company believes that the condition requiring the Grantee to have been continuously employed by Company or a Related Entity from the
date on which the Options are granted to the Grantee to the date of exercise (inclusive) will satisfy the real risk of forfeiture test. Accordingly, it is intended for income tax in relation to the Options to be deferred until they vest and can be
exercised, unless the Grantee’s employment terminates for any reason prior to exercise. If dealing in Shares acquired is further restricted, the taxing point may be deferred further. However, the Company is not providing tax advice, and the
Grantee should consult his or her personal advisor for the precise tax treatment of the Option.
