 SHARES
SUBJECT TO THE PLAN

(a)    Subject to the provisions of Article 9 and Section 3.1(b), the maximum aggregate number of Shares which may be
issued pursuant to all Awards (including Incentive Share Options) (the “Award Pool”) shall initially be 3% of the total number of Shares of the Company issued and outstanding immediately after the completion of the Company’s
initial public offering, plus an annual increase on the first day of each fiscal year of the Company during the term of this Plan commencing with the fiscal year beginning January 1, 2020, by (i) an amount equal to 2% of the total number
of shares issued and outstanding on the last day of the immediately preceding fiscal year, or (ii) such number of Shares as may be determined by the Board; the size of the Award Pool shall be equitably adjusted in the event of any share
dividend, subdivision, reclassification, recapitalization, split, reverse split, combination, consolidation or similar transactions. 

(b)    To the extent that an Award terminates, expires, or lapses for any reason, any Shares subject to the Award shall
again be available for the grant of an Award pursuant to the Plan. To the extent permitted by Applicable Laws, Shares issued in assumption of, or in substitution for, any outstanding awards of any entity acquired in any form or combination by a
Group Entity shall not be counted against Shares available for grant pursuant to the Plan. Shares delivered by the Participant or withheld by the Company upon the exercise of any Award under the Plan, in payment of the exercise price thereof or tax
withholding thereon, may again be optioned, granted or awarded hereunder, subject to the limitations of Section 3.1(a). If any Restricted Shares are forfeited by the Participant or repurchased by the Company, such Shares may again be optioned,
granted or awarded hereunder, subject to the limitations of Section 3.1(a). Notwithstanding the provisions of this Section 3.1(b), no Shares may again be optioned, granted or awarded if such action would cause an Incentive Share Option to
fail to qualify as an incentive share option under Section 422 of the Code.

 3.2    Shares Distributed. Any Shares distributed pursuant to an
Award may consist, in whole or in part, of authorized and unissued Shares, treasury Shares (subject to Applicable Laws) or Shares purchased on the open market. Additionally, at the discretion of the Committee, any Shares distributed pursuant to an
Award may be represented by American Depository Shares. If the number of Shares represented by an American Depository Share is other than on a one-to-one basis, the
limitations of Section 3.1 shall be adjusted to reflect the distribution of American Depository Shares in lieu of Shares.

 ELIGIBILITY AND PARTICIPATION 

4.1    Eligibility. Persons eligible to participate in this Plan include Employees, Consultants, and Directors, as
determined by the Committee. 
 4.2    Participation. Subject to the provisions of the Plan, the Committee may,
from time to time, select from among all eligible individuals, those to whom Awards shall be granted and shall determine the nature and amount of each Award. No individual shall have any right to be granted an Award pursuant to this Plan. 

ARTICLE 5 
 OPTIONS

 5.1    General. The Committee is authorized to grant Options to Participants on the following terms and
conditions: 
 (a)    Exercise Price. The exercise price per Share subject to an Option shall be determined by
the Committee and set forth in the Award Agreement which may be a fixed price or a variable price related to the Fair Market Value of the Shares. The exercise price per Share subject to an Option may be amended or adjusted in the absolute discretion
of the Committee, the determination of which shall be final, binding and conclusive. For the avoidance of doubt, to the extent not prohibited by Applicable Laws or any exchange rule, a downward adjustment of the exercise prices of Options mentioned
in the preceding sentence shall be effective without the approval of the Company’s shareholders or the approval of the affected Participants. 

(b)    Time and Conditions of Exercise. The Committee shall determine the time or times at which an Option may be
exercised in whole or in part, including exercise prior to vesting; provided that the term of any Option granted under the Plan shall not exceed ten years, except as provided in Section 12.1. The Committee shall also determine any conditions,
if any, that must be satisfied before all or part of an Option may be exercised. 

  
 6 

 (c)    Payment. The Committee shall determine the methods by
which the exercise price of an Option may be paid, the form of payment, including, without limitation (i) cash or check denominated in U.S. Dollars, (ii) to the extent permissible under the Applicable Laws, cash or check in Chinese
Renminbi, (iii) cash or check denominated in any other local currency as approved by the Committee, (iv) Shares held for such period of time as may be required by the Committee in order to avoid adverse financial accounting consequences
and having a Fair Market Value on the date of delivery equal to the aggregate exercise price of the Option or exercised portion thereof, (v) after the Trading Date the delivery of a notice that the Participant has placed a market sell order
with a broker with respect to Shares then issuable upon exercise of the Option, and that the broker has been directed to pay a sufficient portion of the net proceeds of the sale to the Company in satisfaction of the Option exercise price; provided
that payment of such proceeds is then made to the Company upon settlement of such sale, (vi) other property acceptable to the Committee with a Fair Market Value equal to the exercise price, or (vii) any combination of the foregoing.
Notwithstanding any other provision of the Plan to the contrary, no Participant who is a member of the Board or an “executive officer” of the Company within the meaning of Section 13(k) of the Exchange Act shall be permitted to pay
the exercise price of an Option in any method which would violate Section 13(k) of the Exchange Act. 

(d)    Effects of Termination of Employment or Service on Options. Termination of employment or service shall have
the following effects on Options granted to the Participants: 
 (i)    Dismissal for Cause. Unless otherwise
provided in the Award Agreement, if a Participant’s employment by or service to the Service Recipient is terminated by the Service Recipient for Cause, the Participant’s Options will terminate upon such termination, whether or not the
Option is then vested and/or exercisable; 
 (ii)    Death or Disability. Unless otherwise provided in the Award
Agreement, if a Participant’s employment by or service to the Service Recipient terminates as a result of the Participant’s death or Disability: 
  

	 	(a)	 the Participant (or his or her legal representative or beneficiary, in the case of the Participant’s
Disability or death, respectively), will have until the date that is 12 months after the Participant’s termination of Employment to exercise the Participant’s Options (or portion thereof) to the extent that such Options were vested and
exercisable on the date of the Participant’s termination of Employment on account of death or Disability; 

  

	 	(b)	 the Options, to the extent not vested and exercisable on the date of the Participant’s termination of
Employment or service, shall terminate upon the Participant’s termination of Employment or service on account of death or Disability; and 

  

	 	(c)	 the Options, to the extent exercisable for the 12-month period
following the Participant’s termination of Employment or service and not exercised during such period, shall terminate at the close of business on the last day of the 12-month period.

  
 7 

 (iii)    Other Terminations of Employment or Service. Unless
otherwise provided in the Award Agreement, if a Participant’s employment by or service to the Service Recipient terminates for any reason other than a termination by the Service Recipient for Cause or because of the Participant’s death or
Disability: 
  

	 	(a)	 the Participant will have until the date that is 90 days after the Participant’s termination of Employment
or service to exercise his or her Options (or portion thereof) to the extent that such Options were vested and exercisable on the date of the Participant’s termination of Employment or service; 

 

	 	(b)	 the Options, to the extent not vested and exercisable on the date of the Participant’s termination of
Employment or service, shall terminate upon the Participant’s termination of Employment or service; and 

  

	 	(c)	 the Options, to the extent exercisable for the 90-day period following
the Participant’s termination of Employment or service and not exercised during such period, shall terminate at the close of business on the last day of the 90-day period. 

5.2    Incentive Share Options. Incentive Share Options may be granted to Employees of the Company or a Subsidiary
of the Company. Incentive Share Options may not be granted to employees of a Related Entity or to Independent Directors or Consultants. The terms of any Incentive Share Options granted pursuant to the Plan, in addition to the requirements of
Section 5.1, must comply with the following additional provisions of this Section 5.2: 
 (a)    Individual
Dollar Limitation. The aggregate Fair Market Value (determined as of the time the Option is granted) of all Shares with respect to which Incentive Share Options are first exercisable by a Participant in any calendar year may not exceed $100,000
or such other limitation as imposed by Section 422(d) of the Code, or any successor provision. To the extent that Incentive Share Options are first exercisable by a Participant in excess of such limitation, the excess shall be considered Non-Qualified Share Options. 
 (b)    Exercise Price. The exercise price of an
Incentive Share Option shall be equal to the Fair Market Value on the date of grant. However, the exercise price of any Incentive Share Option granted to any individual who, at the date of grant, owns Shares possessing more than ten percent of the
total combined voting power of all classes of shares of the Company or any Parent or Subsidiary of the Company may not be less than 110% of Fair Market Value on the date of grant and such Option may not be exercisable for more than five years from
the date of grant. 
 (c)    Transfer Restriction. The Participant shall give the Company prompt notice of any
disposition of Shares acquired by exercise of an Incentive Share Option within (i) two years from the date of grant of such Incentive Share Option or (ii) one year after the transfer of such Shares to the Participant. 

(d)    Expiration of Incentive Share Options. No Award of an Incentive Share Option may be made pursuant to this
Plan after the tenth anniversary of the Effective Date.

from specified causes, and (b) in other cases waive in whole or in part restrictions or forfeiture and repurchase conditions relating to Restricted Shares. 

6.5    Certificates for Restricted Shares. Restricted Shares granted pursuant to the Plan may be evidenced in such

 (d)    if the Participant has suffered a disability, permitted transfers or exercises on
behalf of the Participant by the Participant’s duly authorized legal representative; or

and/or the Participant’s family members, including but not limited to trusts or other entities whose beneficiaries or beneficial owners are the Participant and/or the Participant’s family members, or to such other persons or entities as
may be expressly approved by the Committee, pursuant to such conditions and procedures as the Committee or may establish. Any permitted transfer shall be subject to the condition that the Committee receives evidence satisfactory to it that the
transfer is being made for estate and/or tax planning purposes and on a basis consistent with the Company’s lawful issue of securities. 

Notwithstanding anything else in this Section 8.2.2 to the contrary, but subject to compliance with all Applicable Laws, Incentive Share
Options, Restricted Shares and Restricted Share Units will be subject to any and all transfer restrictions under the Code applicable to such Awards or necessary to maintain the intended tax consequences of such Awards. Notwithstanding clause
(b) above but subject to compliance with all Applicable Laws, any contemplated transfer by gift to “immediate family” as referenced in clause (b) above is subject to the condition precedent that the transfer be approved by the
Administrator in order for it to be effective. 
 8.3    Beneficiaries. Notwithstanding Section 8.2, a
Participant may, in the manner determined by the Committee, designate a beneficiary to exercise the rights of the Participant and to receive any distribution with respect to any Award upon the Participant’s death. A beneficiary, legal guardian,
legal representative, or other person claiming any rights pursuant to the Plan is subject to all terms and conditions of the Plan and any Award Agreement applicable to the Participant, except to the extent the Plan and Award Agreement otherwise
provide, and to any additional restrictions deemed necessary or appropriate by the Committee. If the Participant is married and resides in a community property state, a designation of a person other than the Participant’s spouse as his or her
beneficiary with respect to more than 50% of the Participant’s interest in the Award shall not be effective without the prior written consent of the Participant’s spouse. If no beneficiary has been designated or survives the Participant,
payment shall be made to the person entitled thereto pursuant to the Participant’s will or the laws of descent and distribution. Subject to the foregoing, a beneficiary designation may be changed or revoked by a Participant at any time provided
the change or revocation is filed with the Committee.

its discretion, shall set performance objectives or other vesting criteria which, depending on the extent to which they are met, will determine the number or value of the Awards that will be granted or paid out to the Participants.

of Shares, amalgamation, arrangement or consolidation, spin-off, recapitalization or other distribution (other than normal cash dividends) of Company assets to its shareholders, or any other change affecting

type of shares that may be issued under the Plan (including, but not limited to, adjustments of the limitations in Section 3.1); (b) the terms and conditions of any outstanding Awards (including, without limitation, any applicable performance
targets or criteria with respect thereto); and (c) the grant or exercise price per share for any outstanding Awards under the Plan.

Award for an amount of cash equal to the amount that could have been attained upon the exercise of such Award (and, for the avoidance of doubt, if as of such date the Committee determines in good faith that no amount would have been attained upon

be granted any Award pursuant to the Plan, and neither the Company nor the Committee is obligated to treat Participants, employees, and other persons uniformly. 

13.2    No Shareholders Rights. No Award gives the Participant any of the rights of a shareholder of the Company
unless and until Shares are in fact issued to such person in connection with such Award. 
 13.3    Taxes. No
Shares shall be delivered under the Plan to any Participant until such Participant has made arrangements acceptable to the Committee for the satisfaction of any income and employment tax withholding obligations under Applicable Laws. The Company or

“unfunded” plan for incentive compensation. With respect to any payments not yet made to a Participant pursuant to an Award, nothing contained in the Plan or any Award Agreement shall give the Participant any rights that are greater than
those of a general creditor of the relevant Group Entity. 
 13.6    Indemnification. To the extent allowable
pursuant to Applicable Laws, each member of the Committee or of the Board shall be indemnified and held harmless by the Company from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by such member in connection
with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action or failure to act pursuant to the Plan and against and from any and all amounts paid by him
or her in satisfaction of judgment in such action, suit, or proceeding against him or her; provided he or she gives the Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on
his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled pursuant to the Company’s Memorandum of Association and Articles of Association,
as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless.

Shares in such manner as it deems advisable to ensure the availability of any such exemption. 
 13.10    Governing
Law. The Plan and all Award Agreements shall be construed in accordance with and governed by the laws of the Cayman Islands. 

  
 16 

 13.11    Section 409A. To the extent that the
Committee determines that any Award granted under the Plan is or may become subject to Section 409A of the Code, the Award Agreement evidencing such Award shall incorporate the terms and conditions required by Section 409A of the Code. To
the extent applicable, the Plan and the Award Agreements shall be interpreted in accordance with Section 409A of the Code and the U.S. Department of Treasury regulations and other interpretative guidance issued thereunder, including without
limitation any such regulation or other guidance that may be issued after the Effective Date. Notwithstanding any provision of the Plan to the contrary, in the event that following the Effective Date the Committee determines that any Award may be
subject to Section 409A of the Code and related Department of Treasury guidance (including such Department of Treasury guidance as may be issued after the Effective Date), the Committee may adopt such amendments to the Plan and the applicable
Award agreement or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, that the Committee determines are necessary or appropriate to (a) exempt the Award from
Section 409A of the Code and/or preserve the intended tax treatment of the benefits provided with respect to the Award, or (b) comply with the requirements of Section 409A of the Code and related U.S. Department of Treasury guidance.
