repurchased by the Company at the lower of their original purchase price or their Fair Market Value at the time of repurchase, such Shares shall become available for future grant under the Plan. To the extent not prohibited by the Applicable Law and
the listing requirements of the applicable stock exchange or national market system on which the Ordinary Shares are traded, any Shares covered by an Award which are surrendered (i) in payment of the Award exercise or purchase price or

unless otherwise determined by the Administrator.

officers or directors (the “Management”) to grant such Awards and may limit such authority as the Board determines from time to time.

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
Company’s expense to defend the same.

 (d) Acquisitions and Other Transactions. The Administrator may issue Awards under the
Plan in settlement, assumption or substitution for, outstanding awards or obligations to grant future awards in connection with the Company or a Related Entity acquiring another entity, an interest in another entity or an additional interest in a
Related Entity whether by merger, share purchase, asset purchase or other form of transaction. 
 (e) Deferral of Award Payment. The
Administrator may establish one or more programs 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 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.

Employee, Director or Consultant to exercise any part or all of the Award prior to full vesting of the Award, subject to compliance with the Applicable Laws and approval by the Administrator. Any unvested Shares received pursuant to such exercise
may be subject to a repurchase right in favor of the Company or a Related Entity or to any other restriction the Administrator determines to be appropriate.

term of any Award shall not include any period for which the Grantee has elected to defer the receipt of the Shares or cash issuable pursuant to the Award. (In the case of an Incentive Stock Option granted to an U.S. taxpayer who, at the time
the Incentive Stock Option is granted, owns (or, pursuant to Section 424(d) of the U.S. Code, is deemed to own) stock representing more than 10% of the total combined voting power of all classes of shares of the Company or any Subsidiary
or Affiliate, the term of the Incentive Stock Option will not be longer than ten years from the date of grant).

Awards. Subject to the Applicable Laws, Awards shall be transferable (i) by will and by the laws of descent and distribution and (ii) during the lifetime of the Grantee, only to the extent and in the manner approved by the
Administrator. Notwithstanding the foregoing, the Grantee may designate one or more beneficiaries of the Grantee’s Award in the event of the Grantee’s death on a beneficiary designation form provided by the Administrator. 












 (j) Time of Granting Awards. The date of grant of an Award shall for all purposes be
the date on which the Administrator makes the determination to grant such Award, or such other date as is determined by the Administrator. 

7. Award Exercise or Purchase Price, Consideration and Taxes. 

(a) Exercise or Purchase Price. The exercise or purchase price, if any, for an Award shall be determined by the Administrator. In the
case of Options or SARs granted to U.S. taxpayers, shall not be less than 100% of the Fair Market Value of a Share as of the date of grant. In addition, in the case of an Incentive Stock Option granted to an U.S. taxpayer, who, at the time
the Incentive Stock Option is granted, owns (or, pursuant to Section 424(d) of the U.S. Code, is deemed to own) Shares representing more than 10% of the total combined voting power of all classes of shares of the Company or any Subsidiary
or Affiliate, the per Share exercise price will be no less than 110% of the Fair Market Value per Share on the date of grant. 

Notwithstanding the foregoing provisions of this Section 7(a), in the case of an Award issued pursuant to Section 6(d), 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 including the method of payment, shall be determined by the Administrator. In addition to any other types of consideration the Administrator may determine, the Administrator is authorized to accept as consideration for Shares issued under the
Plan the following: 
 (i) cash; 

(ii) check; 
 (iii) if the
exercise or purchase occurs on or after the Registration Date, or as otherwise permitted by the Administrator, surrender of Shares 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 said Award shall be exercised; 

(iv) with respect to Options, if the exercise occurs on or after the Registration Date, 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; or 
 (v) 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)(iv), 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) Taxes. No Shares shall be delivered under the Plan to any Grantee or other Person
until such Grantee or other Person has made arrangements acceptable to the Administrator for the satisfaction of any income and employment tax withholding obligations under any Applicable Laws. The Grantee shall be responsible for all taxes
associated with the receipt, vest, exercise, transfer and disposal of the Awards and the Shares. Upon exercise of an Award, the Company and/or the Related Entity which is an employer of the Grantee shall have the right to withhold or collect from
Grantee an amount sufficient to satisfy such tax obligations. 
 8. Exercise of Award.

(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 notice of such
exercise 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, including, to the extent selected, use of the
broker-dealer sale and remittance procedure to pay the purchase price as provided in Section 7(b)(iv). 

(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. 
 (d) Restrictions on Exercise.

 Notwithstanding the foregoing, regardless of whether an Award has become vested and exercisable, the Administrator may determine that the
Award shall not be exercised before the consummation of (i) an IPO of the Company, or (ii) a Corporate Transaction or a Change in Control, except as permitted by the applicable Award Agreement. 

9. Conditions Upon Issuance of Shares. 












 (a) Shares shall not be issued pursuant to the exercise of an Award unless the exercise of
such Award and the issuance and delivery of such Shares pursuant thereto shall comply with all Applicable Laws, the M&A and the relevant Award Agreement, and shall be further subject to the approval of counsel for the Company with respect to
such compliance. 
 (b) As a condition to the exercise of an Award, the Company may require the Person exercising such Award to represent and
warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by
any Applicable Laws. 
 (c) As a condition to the exercise of 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 exercising such Award 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. Termination and Repurchase Rights. Upon termination of the Grantee’s Continuous Service for any reason, all unvested Awards
shall be terminated immediately without further effect. To the extent any vested Award is not terminated, following termination of the Grantee’s Continuous Service for any reason, the Company shall have the right (but not the obligation) to
repurchase (the “Repurchase Right”) from the Grantee all or any portion of the vested Awards or the Shares obtained by the Grantee upon exercise of any Awards. The Repurchase Right may be exercised by the Company at any time within
two (2) year after termination of the Grantee’s Continuous Service. The repurchase price shall be as follows: 
 (a) the
consideration payable for the vested Awards or the Shares obtained by the Grantee upon exercise of the Awards shall be made in cash or by cancellation of purchase money indebtedness owed to the Company by the Grantee; and 

(b) the amount of consideration payable for the vested Awards or the Shares obtained by the Grantee upon exercise of the Awards shall be:
(x) in the event of termination of the Grantee’s Continuous Service other than for Cause, the original purchase price actually paid by the Grantee for such vested Awards or such Shares, or the Fair Market Value of such vested Awards or
such Shares on the termination date (after deducting (if have not already done so) the exercise price that would be payable on such vested Awards or such Shares had such vested Awards been exercised immediately prior to the termination date), or
other amount as reasonably determined by the Administrator; and (y) in the event of termination of the Grantee’s Continuous Service for Cause, the nominal value of such vested Awards or such Shares, unless otherwise determined by the
Administrator; 
 If the Company decides to exercise the repurchase right, each holder of the vested Awards or the Shares subject to
repurchase shall (1) immediately execute all necessary documents and take all necessary actions as required by the Applicable Laws, the M&A and the Administrator to give full effect to such repurchase, and (2) provide customary
representations and warranties with respect to such vested Awards or such Shares as the Administrator requires, provided however that, the failure of the holder to make such representations and warranties shall in no way delay or affect the
completion of the repurchase of such Shares or such vested Awards, which shall become effective and be recorded in the Company’s register of members (if applicable) at the moment when the Company makes available to such holder the applicable
repurchase price. 












 11. Adjustments Upon Changes in Capitalization. Subject to any required action by the
shareholders of the Company, the number of Shares covered by each outstanding Award, the number of Shares which have been authorized for issuance under the Plan but as to which no Awards have yet been granted or which have been returned to the Plan,
the exercise or purchase price of each such outstanding Award, the maximum number of Shares with respect to which Awards may be granted to any Grantee in any fiscal year of the Company, as well as any other terms that the Administrator determines
require adjustment shall be proportionately adjusted for (i) any increase or decrease in the number of issued Shares resulting from a share split, reverse share split, share dividend, combination or reclassification of the Shares, or similar
transaction affecting the Shares, (ii) any other increase or decrease in the number of issued Shares effected without receipt of consideration by the Company, or (iii) as the Administrator may determine in its discretion, any other
transaction with respect to Ordinary Shares including a corporate merger, consolidation, acquisition of property or equity, separation (including a spin-off or other distribution of shares or property),
reorganization, liquidation (whether partial or complete) or any similar transaction; provided, however that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of
consideration.” Such adjustment shall be made by the Administrator and its determination shall be final, binding and conclusive. Except as the Administrator determines, no issuance by the Company of shares of any class, or securities
convertible into shares of any class, shall affect, and no adjustment by reason hereof shall be made with respect to, the number or price of Shares subject to an Award. In the event of a Spin-off Transaction,
the Administrator may in its discretion make such adjustments and take such other action as it deems appropriate with respect to outstanding Awards under the Plan, including but not limited to: (i) adjustments to the number and kind of Shares,
the exercise or purchase price per Share and the vesting periods of outstanding Awards, (ii) prohibit the exercise of Awards during certain periods of time prior to the consummation of the Spin-off
Transaction, or (iii) the substitution, exchange or grant of Awards to purchase securities of the Subsidiary; provided that the Administrator shall not be obligated to make any such adjustments or take any such action hereunder. 

12. Corporate Transactions and Changes in Control. 

(a) Acceleration of Award Upon Corporate Transaction or Change in Control. 

(i) Corporate Transaction. Except as provided otherwise in an individual Award Agreement or in any other written agreement between the
Company and a Grantee, in the event of a Corporate Transaction (other than a Corporate Transaction which also is a Change in Control), each Award can be Assumed or Replaced immediately prior to the specified effective date of such Corporate
Transaction, for the portion of each Award that is neither Assumed nor Replaced, such portion of the Award shall automatically become fully vested and exercisable and be released from any repurchase or forfeiture rights (other than repurchase rights
exercisable at Fair Market Value) for all of the Shares at the time represented by such portion of the Award, immediately prior to the specified effective date of such Corporate Transaction, provided that the Grantee’s Continuous Service has
not terminated prior to such date. The portion of the Award that is not Assumed or Replaced shall terminate under subsection (b) of this Section to the extent not exercised prior to the consummation of such Corporate Transaction. 












 (ii) Change in Control. Except as provided otherwise in an individual Award
Agreement or in any other written agreement between the Company and a Grantee, in the event of a Change in Control (other than a Change in Control which also is a Corporate Transaction), each Award which is at the time outstanding under the Plan
shall automatically become fully vested and exercisable and be released from any repurchase or forfeiture rights (other than repurchase rights exercisable at Fair Market Value) for all of the Shares at the time represented by such Award, immediately
prior to the specified effective date of such Change in Control, provided that the Grantee’s Continuous Service has not terminated prior to such date. 

(b) Termination of Award to the Extent Not Assumed and Replaced in Corporate Transaction. Effective upon the consummation of a Corporate
Transaction, all outstanding Awards under the Plan shall terminate, provided however that, all such Awards shall not terminate to the extent they are Assumed or Replaced in connection with the Corporate Transaction. 

(c) Other Mechanisms. Except as provided otherwise in an individual Award Agreement or in any other written agreement between the
Company and a Grantee, and subject to Applicable Laws, in the event of a Corporate Transaction or a Change in Control, the Administrator may provide for other mechanisms, such as (1) termination and payment of any Awards in cash based on the
value of the Shares on the date of the Corporate Transaction or the Change in Control (as the case may be), or (2) allowing any Grantee the right to exercise any outstanding Awards during a specified period of time determined by the
Administrator. 
 13. Effective Date and Term of Plan. The Plan shall become effective upon the later to occur of its adoption by the
Board or its approval by the shareholders of the Company. The Plan shall continue in effect for a term of ten (10) years after the date of adoption, unless sooner terminated. Subject to Applicable Laws, Awards may be granted under the Plan upon
its becoming effective. 
 14. Amendment, Suspension or Termination of the Plan. 

(a) The Board may at any time amend (including extend the term of the Plan), 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 or if such amendment would change any of the provisions of Section 4(b)(vi) or
this Section 14(a). 
 (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 12, above) shall not materially adversely affect any rights under Awards already granted to a Grantee. 












 15. Source of Shares. 

(a) 1,538,800 Shares have been issued to the ESOP Entity by the Company to satisfy the requirements of the Plan. As provided under the
Shareholders Agreement or otherwise agreed by the Shareholders, additional Shares shall be allocated to the ESOP Entity by way of Share transfer or issuance of new Shares. 

(b) Unless otherwise determined by the Administrator, the Company shall carry out the Plan through the ESOP Entity. Specifically, (i) the
exercise of Awards, repurchase of vested Awards or Shares issued pursuant to vested Awards and any other types of execution in connection with the Awards shall be carried out via the ESOP Entity; (ii) the Shares under any Award shall be
represented by the class B ordinary shares (“Class B Shares”) of the ESOP Entity. The ESOP Entity shall have 1,538,800 Class B Shares and one Class B Share represents one Share issued pursuant to any Award under this Plan;
(iii) the Grantee will obtain the Class B Shares of the ESOP Entity or the economic interests related thereto after he/she exercising the Awards, which represent the underlying Shares under such Awards; (iv) any mention of
“Shares” under this Plan shall also mean the Class B Shares represent such Shares where applicable. 
 16. 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. 

17. 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. 
 18. Vesting Schedule. The Awards to be issued to any Grantee under the Plan shall be
subject to the vesting schedule as specified in the Award Agreement of such Grantee. The Administrator shall have the right to adjust the vesting schedule of the Awards granted to the Grantees. 

19. Drag-Along Events. Except as provided in the applicable Award Agreement, in the event
of a Drag-Along Event, the Grantees who hold any Shares upon exercise of the Award shall sell, transfer, convey or assign all of their Shares pursuant to, and so as to give effect to, the Drag-Along Event, and each of such Grantees shall grant to the Board or a Person designated by the Board, a power of attorney to transfer, sell, convey and assign his/her Shares and to do and carry out all acts and
to execute all documents that are necessary or advisable to complete the Drag-Along Event. 












 20. IPO. In the case of an IPO, the Grantees shall enter into any agreements with any
underwriter, coordinator, bankers or sponsor elected by the Company for the purpose of the IPO, and each of such Grantees shall grant to the Board or a Person designated by the Board, a power of attorney to enter into any agreements with any
underwriter, coordinator, bankers or sponsor elected by the Company and to do and carry out all the acts and to execute all the documents that are necessary or advisable to complete the IPO. 

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. 
 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.

2019 STOCK INCENTIVE PLAN 

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 to_([ 🌑 ]) ([insert Identification document and No.]) (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 2019 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. Unless otherwise defined herein, the terms used herein shall have the same meanings ascribed to them in the Plan. 

2. Exercise of Option. 
  

	 	1.	 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. If the Option is not exercised prior to the Expiration
Date, it will terminate and no longer be exercisable. Further, the Option shall be subject to the provisions of Section 12 of the Plan relating to the exercisability or termination of the Option in the event of a Corporate Transaction or Change
in Control. 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.



  

	 	2.	 Method of Exercise. The Grantee may exercise the Option by delivery of an exercise notice (a form of
which is attached as Exhibit A) 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, which shall be
deemed to be satisfied in accordance with Section 4(d) below. 


  

	 	3.	 Taxes. The Grantee shall be responsible for all taxes associated with the receipt, vesting, exercise,
transfer and disposal of the Option and the Shares. 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 income tax and employment tax withholding obligations. 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 withholding obligations. 















	 	4.	 Other Agreements. As a condition to the exercise of an Award, 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. 



3. Grantee’s Representations 

. The Grantee understands that neither the Option nor the Shares exercisable pursuant to the Option have been registered under the Securities
Act of 1933 (as amended), any United States securities laws or any securities laws of any other jurisdiction. In the event the Shares purchasable pursuant to the exercise of the Option have not been registered under the Securities Act of 1933 (as
amended) (or any securities laws of any other jurisdiction), at the time the Option is exercised, the Grantee shall, if requested by the Company, concurrently with the exercise of all or any portion of the Option, deliver to the Company his or her
Investment Representation Statement in the form attached hereto as Exhibit B. 
 4. 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: 
  

	 	5.	 cash; 


  

	 	6.	 check; 


  

	 	7.	 if the exercise occurs on or after the Registration Date, or as otherwise permitted by the Administrator,
surrender of Shares 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; or 


  

	 	8.	 if the exercise occurs on or after the Registration Date, 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. 


 5.
Restrictions on Exercise. 













	 	9.	 The Option may not be exercised until such time as the Plan has been approved by the Company.



  

	 	10.	 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. 



 

	 	11.	 Notwithstanding the foregoing, regardless of whether an Option has otherwise become exercisable, the Option may
not be exercised before the consummation of (i) an IPO of the Company, (ii) a Corporate Transaction, or (iii) the Change in Control, unless approved by the Administrator. 



 

	 	12.	 Notwithstanding anything provided to the contrary hereof, if the exercise of the Option within the applicable
time periods set forth in Section 6, 7 and 8 of this Option Agreement is prevented by Section 5(b) or (c) above, the Option shall remain exercisable until three (3) months after the date the Grantee is notified by the Company
that the Option is exercisable, except as otherwise determined by the Administrator, but in any event no later than the Expiration Date set forth in the Notice. 



 

	 	13.	 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. 



6. Termination or Change of Continuous Service. 













	 	14.	 In the event the Grantee’s Continuous Service terminates, other than for Cause, Disability and death, the
portion of the Option that was vested at the date of such termination (the “Termination Date”) shall remain exercisable (unless otherwise determined by the Administrator), provided that the Grantee may only exercise the vested portion of
the Option during the Post-Termination Exercise Period (subject to Section 5 above). The Post-Termination Exercise Period shall commence on the Termination Date.
Notwithstanding the foregoing, in no event, however, shall the Option be exercised later than the Expiration Date set forth in the Notice. Except as provided in Sections 7 and 8 below, if any Option was unvested on the Termination Date, or if
the Grantee does not exercise the vested portion of any Option within the Post-Termination Exercise Period (subject to Section 5 above), such Option shall terminate immediately and automatically.



  

	 	15.	 In the event the Grantee’s Continuous Service terminates for Cause, all of the Option granted to the
Grantee (vested or unvested) and the Grantee’s right to exercise such Option shall, except as otherwise determined by the Administrator, terminate immediately and automatically on the date of the termination of the Grantee’s Continuous
Service (also the “Termination Date”). If upon written approval of the Administrator, any portion of the Option that was vested at the Termination Date is not terminated, then such vested portion of the Option shall be subject to the same
exercise method set forth in Section 6(a) above and other restrictions set forth in this Option Agreement and the Plan. 


  

	 	16.	 In the event of the Grantee’s change in status from Employee, Director or Consultant to any other status
of Employee, Director or Consultant, the Option shall remain in effect unless otherwise determined by the Administrator. In the event of the Grantee’s change in status from Employee to Director or Consultant, vesting of the Option shall
continue only to the extent determined by the Administrator as of such change in status. 


  

	 	17.	 In the event the Grantee’s Continuous Service terminates for any reason, the Company shall have the right
(but not obligation) to exercise the Repurchase Right described under Section 15 hereof. 


 7. Disability of
Grantee. Unless otherwise determined by the Administrator, in the event the Grantee’s Continuous Service terminates as a result of his or her Disability (as defined in the Plan), the Grantee may, but only within twelve (12) months
commencing on the Termination Date (but in no event later than the Expiration Date), exercise the portion of the Option that was vested on the Termination Date (subject to section 5 above). To the extent that any Option was unvested on the
Termination Date, or if the Grantee does not exercise the vested portion of any Option within the time specified herein, such Option shall terminate immediately and automatically. 

8. Death of Grantee. Unless otherwise determined by the Administrator, in the event of the termination of the Grantee’s Continuous
Service as a result of his or her death, or in the event of the Grantee’s death during the Post-Termination Exercise Period or during the twelve (12) month period following the Grantee’s
termination of Continuous Service as a result of his or her Disability, the Person who acquired the right to exercise the Option pursuant to Section 9 may exercise the portion of the Option that was vested at the date of termination within
twelve (12) months commencing on the date of death (but in no event later than the Expiration Date) (subject to section 5 above). To the extent that any Option was unvested on the date of death, or if the vested portion of any Option is
not exercised within the time specified herein, such Option shall terminate immediately and automatically. 












 9. Transferability of Option. 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 may be transferred during the lifetime of the Grantee only 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 8, 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. 

10. Term of Option. The Option must be exercised no later than the Expiration Date set forth in the Notice or such earlier date as
otherwise provided herein. After the Expiration Date or such earlier date, the Option shall be of no further force or effect and may not be exercised. 

11. Company’s Right of First Refusal. 
  

	 	18.	 Transfer Notice. Neither the Grantee nor a transferee (either being sometimes referred to herein as the
“Holder”) shall transfer, sell, hypothecate, encumber or otherwise dispose of any Shares or any right or interest therein without first obtaining the prior written consent of the Company and complying with the provisions of this
Section 11 (as well as any applicable provisions of the Shareholders Agreement and the M&A). In the event the Holder desires to accept a bona fide third-party offer for any or all of the Shares, the
Holder shall provide the Company with a written notice (the “Transfer Notice”), stating (1) Holder’s intention to transfer, (2) the name of the proposed transferee, (3) the number of Shares to be transferred (the
“Offered Shares”), and (4) the proposed transfer price or value and the key terms and conditions thereof. If the Grantee proposes to transfer any Shares to more than one transferee, the Grantee shall provide a separate Transfer Notice
with respect to each proposed transfer to each transferee. The Grantee shall provide the Company with the term sheet or other documents signed by both the Grantee and the proposed transferee, showing the commitment of the Grantee and the proposed
transferee for the transfer of the Offered Shares to the proposed transferee, subject to the terms and conditions of this Option Agreement, the Shareholders Agreement and the M&A. 



 

	 	19.	 Bona Fide Transfer. If the Administrator determines in good faith that the information provided by the
Grantee in the Transfer Notice is insufficient to establish the bona fide nature of a proposed voluntary transfer, the Company shall give the Grantee a written notice of the Grantee’s failure to comply with the procedure described in this
Section 11, and the Grantee shall have no right to transfer any Offered Shares without first complying with the procedure described in this Section 11. The Grantee shall not be permitted to transfer the Offered Shares if the proposed
transfer is not bona fide. In addition, if the proposed transferee or an Affiliate of the proposed transferee is a Person which carries out business in direct competition of the business of the Company and the Related Entities, the Administrator has
the right to require the Holder not to transfer the Offered Shares to such proposed transferee. 















	 	20.	 First Refusal Exercise Notice. The Company shall have the right to purchase (or designate other
Person(s) to purchase) (the “Right of First Refusal”) all, but not less than all, of the Offered Shares which are described in the Transfer Notice at any time within forty-five (45) days after
receipt of the Transfer Notice (the “Option Period”). The Right of First Refusal shall be exercised by delivery of a written notice (the “First Refusal Exercise Notice”) to the Holder. The Offered Shares shall be repurchased by
the Company at the per share price or value, and in accordance with the terms conditions, as stated in the Transfer Notice (subject to Section 11(d) below). 



 

	 	21.	 Payment Terms. The Company shall consummate the purchase of the Offered Shares on the terms set forth in
the Transfer Notice within sixty (60) days after delivery of the First Refusal Exercise Notice; provided, however, that in the event the Transfer Notice provides for the payment for the Offered Shares other than in cash, the Company and/or its
assigns shall have the right to pay for the Offered Shares by the discounted cash equivalent of the consideration described in the Transfer Notice as reasonably determined by the Administrator. Upon payment for the Offered Shares to the Holder or
into escrow for the benefit of the Holder, the Company or its assigns shall become the legal and beneficial owner of the Offered Shares and all rights and interest therein or related thereto, and the Company shall have the right to transfer the
Offered Shares to its own name or its assigns without further action by the Holder. 


  

	 	22.	 Assignment. Whenever the Company shall have the right to purchase Shares under this Right of First
Refusal, the Company may designate and assign one or more employees, officers, directors or shareholders of the Company or other Persons or organizations, to exercise all or a part of the Company’s Right of First Refusal. 



 

	 	23.	 Non-Exercise. If the Company and/or its assigns fail to
exercise or do not collectively elect to exercise the Right of First Refusal within the Option Period (or such earlier time if the Company and/or its assigns notify the Holder that they will not exercise the Right of First Refusal), then the sale
and transfer of the Offered Shares by the Holder shall be subject to the Shareholders Agreement and the M&A. If no shareholder of the Company elects to exercise its right of first refusal available to it under the Shareholders Agreement and the
M&A with respect to the Offered Shares, then the Holder may transfer the Offered Shares upon the terms and conditions stated in the Transfer Notice, provided that: 



 

	 	1.	 The transfer is made within ninety (90) days of the earlier of (A) the date the Company and/or its
assigns notify the Holder that the Right of First Refusal herein and the right of first refusal of the shareholders of the Company under the Shareholders Agreement and the M&A will not be exercised or (B) the expiration of the Option Period
and the expiration of the option period for other shareholders’ right of first refusal as set forth in the Shareholders Agreement and the M&A; and 















	 	2.	 The transferee agrees in writing that such Shares shall be held subject to the provisions of this Option
Agreement, the Shareholders Agreement and the M&A; and 


  

	 	3.	 Any transfer of the Offered Shares at a price lower than that stated in the Transfer Notice and/or upon the
terms and conditions more favorable than those provided in the Transfer Notice shall be subject to this Section 11 again. 



The Company shall have the right to demand further assurances from the Grantee and the transferee (in a form satisfactory to the Company) that
the transfer of the Offered Shares was actually carried out on the terms and conditions described in the Transfer Notice. No Offered Shares shall be transferred on the books of the Company until the Company has received such assurances, if so
demanded, and has approved the proposed transfer as bona fide. 
  

	 	24.	 Expiration of Transfer Period. Following such 90 day period, no transfer of the Offered Shares and
no change in the terms of the transfer as stated in the Transfer Notice (including the name of the proposed transferee) shall be permitted without a new written Transfer Notice prepared and submitted in accordance with the requirements of this
Section 11. 


  

	 	25.	 Termination of Right of First Refusal. The provisions of this Right of First Refusal shall terminate as
to all Shares upon the consummation of the IPO. 


  

	 	26.	 Additional Shares or Substituted Securities. In the event of any transaction described in
Sections 11 and 12 of the Plan, any new, substituted or additional securities or other property which is by reason of any such transaction distributed with respect to the Shares shall be immediately subject to the Right of First Refusal, but
only to the extent the Shares are at the time covered by such right. 


 12.
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. 

13. 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. 

14. Tax Consequences. THE GRANTEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THE OPTION OR DISPOSING OF THE SHARES. The Grantee
shall pay all taxes and duties that are required by the Applicable Laws to be paid by him/her in connection with the transactions contemplated by this Option Agreement (including but not limited to the exercise of the Option and the disposal of the
Shares). The Company (including the Subsidiaries, Affiliates and other shareholders of the Company) shall have no obligation to pay any tax of any nature that is required by the Applicable Laws to be paid by the Grantee in connection with the
transactions contemplated by this Option Agreement. 












 15. Repurchase Right. 

 

	 	27.	 Subject to Sections 6, 7, and 8 above, upon termination of the Grantee’s Continuous Service for any
reason, all unvested portion of the Option shall be terminated immediately without further effect, and upon termination of the Grantee’s Continuous Service for Cause, all Options (vested or unvested) held by the Grantee shall be terminated
immediately without further effect. To the extent any vested portion of the Option is not terminated, following termination of the Grantee’s Continuous Service for any reason, the Company shall have the right (but not the obligation) to
repurchase (the “Repurchase Right”) from the Grantee all or any portion of the vested Option or the Shares obtained by the Grantee upon exercise of any Option. The Repurchase Right may be exercised by the Company at any time within
two (2) year after termination of the Grantee’s Continuous Service. The repurchase price shall be as follows: 


  

	 	4.	 the consideration payable for the vested portion of the Option or the Shares obtained by the Grantee upon
exercise of the Option shall be made in cash or by cancellation of purchase money indebtedness owed to the Company by the Grantee; and 


  

	 	5.	 the amount of consideration payable for the vested portion of the Option or the Shares obtained by the Grantee
upon exercise of the Option shall be: (x) in the event of termination of the Grantee’s Continuous Service other than for Cause, the original purchase price actually paid by the Grantee for such vested Option or such Shares, or the Fair
Market Value of such vested Option or such Shares on the Termination Date (after deducting (if have not already done so) the Exercise Price that would be payable on such vested Option or such Shares had such vested Option been exercised immediately
prior to the Termination Date), or other amount as reasonably determined by the Administrator; and (y) in the event of termination of the Grantee’s Continuous Service for Cause, the nominal value of such vested Option or such Shares,
unless otherwise determined by the Administrator. 


  

	 	28.	 If the Company decides to exercise the Repurchase Right, the Grantee shall (1) immediately execute all
necessary documents and take all necessary actions as required by the Applicable Laws, the M&A and the Administrator to give full effect to such repurchase, and (2) provide customary representations and warranties with respect to such
vested Option or such Shares as the Administrator requires, provided however that, the failure of the Grantee to make such representations and warranties shall in no way delay or affect the completion of the repurchase of such Shares or vested
Option, which shall become effective and be recorded in the Company’s register of members (if applicable) at the moment when the Company makes available to the Grantee the applicable repurchase price. 



 

	 	29.	 Upon approval by the Administrator, the Company has the right (but not the obligation) to reach a mutual
agreement with the Grantee for the repurchase all or any portion of the vested Option or the Shares obtained by the Grantee upon exercise of the Option before termination of the Grantee’s Continuous Service. 














 16. Adjustments Upon Changes in Capitalization. The number of the Shares vested or
unvested pursuant to this Option Agreement shall be entitled to adjustment upon changes in capitalization of the Company pursuant to Section 11 of the Plan. 

17. Lock-Up Agreement. 

 

	 	30.	 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. 


  

	 	31.	 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. 


  

	 	32.	 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. 



18. Drag-Along Events. The Grantee agrees that in the event of a Drag-Along Event, if it holds any Shares upon exercise of the Option, it shall sell, transfer, convey or assign all of his/her Shares pursuant to, and so as to give effect to, the
Drag-Along Event. For this purpose, the Grantee hereby irrevocably grants to the Board or the Person designated by the Board a power of attorney to transfer, sell, convey and assign his/her Shares and to do

coordinator, bankers or sponsor elected by the Company and to do and carry out all the acts and to execute all the documents that are necessary or advisable to complete the IPO, on behalf of the Grantee. 












 20. Power of Attorney. The Grantee hereby grants a power of attorney to the Board or
any Person designated by the Board to (i) exercise the voting rights (if any) with respect to the Shares (including executing any shareholders’ resolutions), and (ii) 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. 
 21. Entire Agreement and Amendment. The Notice, the Plan and this Option Agreement
(together with the documents referenced in Section 2(d) hereof) constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings, commitments and agreements of the
Company and the Grantee with respect to the subject matter hereof, and may not be modified or amended adversely to the Grantee’s interest in material aspects except by means of a written form signed by the Company and the Grantee. Nothing in

if delivered to such service agent. 
 28. Covenant After Termination of the Grantee’s Continuous Service. Unless otherwise
approved by the Administrator, if after the termination of the Grantee’s Continuous Service, the Grantee is determined to be in material breach of any non-compete obligation, non-solicitation obligation or non-disclosure obligation entered into by the Grantee with the Company or any Related Entity, without limiting other legal remedies available to
the Company or any Related Entity, all of the Option granted to the Grantee (vested or unvested) and the Grantee’s right to exercise such Option shall terminate immediately and automatically, and upon request by the Company, all vested Option

Representations of the Grantee. The Grantee acknowledges that the Grantee has received, read and understood the Notice, the Plan and
the Option Agreement and agrees to abide by and be bound by their terms and conditions. 
 Rights as Shareholder. Until the Shares

respect to the Shares/Class B Shares, notwithstanding the exercise of the Option. The Company/ESOP Entity shall update (or cause to be updated) its register of members to reflect the issuance of the Shares/Class B Shares promptly after the Option is

 The Grantee shall enjoy rights as a shareholder until such time as the Grantee disposes of the

 In connection with the purchase of the above-listed Securities, the undersigned
Grantee represents to the Company the following: 
 1. Grantee is aware of the Company’s business affairs and financial condition and
has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Grantee is acquiring these Securities for investment for Grantee’s own account only and not with a view to, or for
resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 

2. Grantee acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have not
been registered under the Securities Act (or the securities laws of any other jurisdiction) in reliance upon a specific exemption therefrom, which exemption depends upon among other things, the bona fide nature of Grantee’s investment intent as
expressed herein. Grantee further understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Grantee further acknowledges and
understands that the Company is under no obligation to register the Securities. Grantee understands that the certificate evidencing the Securities will be imprinted with a legend which prohibits the transfer of the Securities unless they are
registered or such registration is not required in the opinion of counsel satisfactory to the Company. 
 3. Grantee is familiar with the
provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of the grant of the Option to the Grantee, the exercise will be exempt
from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934 (as amended), ninety (90) days thereafter (or such longer
period as any market stand-off agreement may require) the Securities exempt under Rule 701 may be resold, subject to the satisfaction of certain of the conditions specified by Rule 144, including: (1) the
resale being made through a broker in an unsolicited “broker’s transaction” or in transactions directly with a market maker (as said term is defined under the Securities Exchange Act of 1934 (as amended)); and, in the case of an
affiliate, (2) the availability of certain public information about the Company, (3) the amount of Securities being sold during any three month period not exceeding the limitations specified in Rule 144(e), and (4) the timely filing
of a Form 144, if applicable. 












 In the event that the Company does not qualify under Rule 701 at the time of grant of the
Option, then the Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which requires the resale to occur not less than one year after the later of the date the Securities were sold by the Company or the
date the Securities were sold by an affiliate of the Company, within the meaning of Rule 144; and, in the case of acquisition of the Securities by an affiliate, or by a non-affiliate who subsequently holds the
Securities less than two (2) years, the satisfaction of the conditions set forth in sections (1), (2), (3) and (4) of the paragraph immediately above. 

4. Grantee further understands that in the event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration under
the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed
its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 will have a substantial burden of proof in establishing that an exemption from registration
is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. Grantee understands that no assurances can be given that any such other registration exemption
will be available in such event. 
 5. Grantee represents that Grantee is a resident of the state of ____________.
