 Exhibit 10.1 

MOLECULAR DATA INC. 2018 SHARE PLAN 

SECTION 1. ESTABLISHMENT AND PURPOSE. 

The purpose of this Plan is to offer persons selected by the Company an opportunity to acquire a proprietary interest in the success of the
Company, or to increase such interest, by acquiring Shares. The Plan provides both for the direct award or sale of Shares and for the grant of Options to purchase Shares and the grant of Restricted Share Units over Shares. Options granted under the
Plan may be ISOs intended to qualify under Code Section 422 or Nonstatutory Options which are not intended to so qualify. 

Capitalized terms are defined in Section 13. 

SECTION 2. ADMINISTRATION. 
 (a)
Committees of the Board of Directors. The Plan may be administered by one or more Committees. Each Committee shall consist, as required by applicable law, of one or more members of the Board of Directors who have been appointed by the Board
of Directors. Each Committee shall have such authority and be responsible for such functions as the Board of Directors has assigned to it. If no Committee has been appointed, the entire Board of Directors shall administer the Plan. Any reference to
the Board of Directors in the Plan shall be construed as a reference to the Committee (if any) to whom the Board of Directors has assigned a particular function. 

(b) Authority of the Board of Directors. Subject to the provisions of the Plan, the Board of Directors shall have full authority and
discretion to take any actions it deems necessary or advisable for the administration of the Plan. Notwithstanding anything to the contrary in the Plan, with respect to the terms and conditions of awards granted to Participants outside the United
States, the Board of Directors may vary from the provisions of the Plan to the extent it determines it necessary and appropriate to do so; provided that it may not vary from those Plan terms requiring shareholder approval pursuant to
Section 11(d) below. All decisions, interpretations and other actions of the Board of Directors shall be final and binding on all Purchasers, all Optionees and all persons deriving their rights from a Purchaser or Optionee. 

SECTION 3. ELIGIBILITY. 
 (a) General
Rule. Only Employees, Outside Directors and Consultants shall be eligible for the grant of Nonstatutory Options, Restricted Share Units or the direct award or sale of Shares. Only Employees shall be eligible for the grant of ISOs. 

(b) Ten-Percent Shareholders. A person who owns more than 10% of the total combined voting
power of all classes of outstanding shares of the Company, its Parent or any of its Subsidiaries shall not be eligible for the grant of an ISO unless (i) the Exercise Price is at least 110% of the Fair Market Value of a Share on the Date of
Grant (but in no event less than the par value per Share), and (ii) such ISO by its terms is not exercisable after the expiration of five years from the Date of Grant. For purposes of this Subsection (b), in determining share ownership,
the attribution rules of Code Section 424(d) shall be applied. 












 SECTION 4. SHARES SUBJECT TO PLAN. 

(a) Basic Limitation. Not more than 48,676,179 Shares may be issued under the Plan, subject to Subsection (b) below and
Section 9(a). All of these Shares may be issued upon the exercise of ISOs. The number of Shares that are subject to Options, Restricted Share Units or other rights outstanding at any time under the Plan may not exceed the number of Shares that
then remain available for issuance under the Plan. The Company, during the term of the Plan, shall at all times reserve and keep available sufficient Shares to satisfy the requirements of the Plan. Shares offered under the Plan may be authorized but
unissued Shares or treasury Shares. 
 (b) Additional Shares. In the event that Shares previously issued under the Plan are
reacquired by the Company, such Shares shall be added to the number of Shares then available for issuance under the Plan. In the event that Shares that otherwise would have been issuable under the Plan are withheld by the Company in payment of the
Purchase Price, Exercise Price or withholding taxes, such Shares shall remain available for issuance under the Plan. In the event that an outstanding Option or other right for any reason expires or is canceled, the Shares allocable to the
unexercised portion of such Option or other right shall be added to the number of Shares then available for issuance under the Plan. 
 SECTION 5. TERMS
AND CONDITIONS OF AWARDS OR SALES. 
 (a) Grant or Purchase Agreement. Each award of Shares under the Plan shall be evidenced by a
Share Grant Agreement between the Grantee and the Company. Each sale of Shares under the Plan (other than upon exercise of an Option) shall be evidenced by a Share Purchase Agreement between the Purchaser and the Company. Such award or sale shall be
subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions which are not inconsistent with the Plan and which the Board of Directors deems appropriate for inclusion in a Share Grant Agreement or
Share Purchase Agreement. The provisions of the various Share Grant Agreements and Share Purchase Agreements entered into under the Plan need not be identical. 

(b) Duration of Offers and Nontransferability of Rights. Any right to purchase Shares under the Plan (other than an Option) shall
automatically expire if not exercised by the Purchaser within 30 days (or such other period as may be specified in the Award Agreement) after the grant of such right was communicated to the Purchaser by the Company. Such right is not transferable
and may be exercised only by the Purchaser to whom such right was granted. 
 (c) Purchase Price. The Purchase Price of Shares to be
offered under the Plan, if newly issued, shall not be less than the par value of such Shares. Subject to the foregoing, the Board of Directors shall determine the Purchase Price of Shares to be offered under the Plan at its sole discretion. The
Purchase Price shall be payable in a form described in Section 7. 

  
 E-2 













 SECTION 6. TERMS AND CONDITIONS OF OPTIONS. 

(a) Option Agreement. Each grant of an Option under the Plan shall be evidenced by a Share Option Agreement between the Optionee and the
Company. The Option shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions that are not inconsistent with the Plan and that the Board of Directors deems appropriate for inclusion in a
Share Option Agreement. The provisions of the various Share Option Agreements entered into under the Plan need not be identical. 
 (b)
Number of Shares. Each Share Option Agreement shall specify the number of Shares that are subject to the Option and shall provide for the adjustment of such number in accordance with Section 9. The Share Option Agreement shall also specify
whether the Option is an ISO or a Nonstatutory Option. 
 (c) Exercise Price. Each Share Option Agreement shall specify the Exercise
Price. The Exercise Price of an Option shall not be less than 100% of the Fair Market Value of a Share on the Date of Grant unless otherwise approved by the Board of Directors or its appointed Committees, but in no event shall the Exercise Price be
less than the par value per Share at issuance. In the case of an ISO a higher percentage may be required by Section 3(b). Subject to the preceding sentence, the Exercise Price shall be determined by the Board of Directors at its sole
discretion. The Exercise Price shall be payable in a form described in Section 7. This Subsection (c) shall not apply to an Option granted pursuant to an assumption of, or substitution for, another option in a manner that complies with
Code Section 424(a) (whether or not the Option is an ISO). 
 (d) Exercisability. Each Share Option Agreement shall specify the
date when all or any installment of the Option is to become exercisable. No Option shall be exercisable unless the Optionee (i) has delivered an executed copy of the Share Option Agreement to the Company or (ii) otherwise agrees to be
bound by the terms of the Share Option Agreement. The Board of Directors shall determine the exercisability provisions of the Share Option Agreement at its sole discretion. 

(e) Basic Term. The Share Option Agreement shall specify the term of the Option. The term shall not exceed 10 years from the Date of
Grant, and in the case of an ISO a shorter term may be required by Section 3(b). Subject to the preceding sentence, the Board of Directors at its sole discretion shall determine when an Option is to expire. 

(f) Termination of Service (Except by Death). Except as otherwise provided in a Share Option Agreement, if an Optionee’s Service
terminates for any reason other than the Optionee’s death, then the Optionee’s Options shall expire on the earliest of the following dates: 

(i) The expiration date determined pursuant to Subsection (e) above; 

  
 E-3 













 (ii) The date three months after the termination of the Optionee’s
Service for any reason other than Disability, or such earlier or later date as the Board of Directors may determine (but in no event earlier than 30 days after the termination of the Optionee’s Service); or 

(iii) The date six months after the termination of the Optionee’s Service by reason of Disability, or such later date as
the Board of Directors may determine. 
 The Optionee may exercise all or part of the Optionee’s Options at any time before the expiration of such
Options under the preceding sentence, but only to the extent that such Options had become exercisable before the Optionee’s Service terminated (or became exercisable as a result of the termination) and the underlying Shares had vested before
the Optionee’s Service terminated (or vested as a result of the termination). The balance of such Options shall lapse when the Optionee’s Service terminates. In the event that the Optionee dies after the termination of the Optionee’s
Service but before the expiration of the Optionee’s Options, all or part of such Options may be exercised (prior to expiration) by the executors or administrators of the Optionee’s estate or by any person who has acquired such Options
directly from the Optionee by beneficiary designation, bequest or inheritance, but only to the extent that such Options had become exercisable before the Optionee’s Service terminated (or became exercisable as a result of the termination) and
the underlying Shares had vested before the Optionee’s Service terminated (or vested as a result of the termination). 
 (g) Leaves
of Absence. For purposes of Subsection (f) above, Service shall be deemed to continue while the Optionee is on a bona fide leave of absence, if such leave was approved by the Company in writing and if continued crediting of Service for this
purpose is expressly required by the terms of such leave or by applicable law (as determined by the Company). 
 (h) Death of
Optionee. Except as otherwise provided in a Share Option Agreement, if an Optionee dies while the Optionee is in Service, then the Optionee’s Options shall expire on the earlier of the following dates: 

(i) The expiration date determined pursuant to Subsection (e) above; or 

(ii) The date 12 months after the Optionee’s death, or such earlier or later date as the Board of Directors may determine
(but in no event earlier than six months after the Optionee’s death). 

  
 E-4 













 All or part of the Optionee’s Options may be exercised at any time before the expiration of such
Options under the preceding sentence by the executors or administrators of the Optionee’s estate or by any person who has acquired such Options directly from the Optionee by beneficiary designation, bequest or inheritance, but only to the
extent that such Options had become exercisable before the Optionee’s death (or became exercisable as a result of the death) and the underlying Shares had vested before the Optionee’s death (or vested as a result of the Optionee’s
death). The balance of such Options shall lapse when the Optionee dies. 
 (i) Pre-Exercise
Restrictions on Transfer of Options or Shares. An Option shall be transferable by the Optionee only by (i) a beneficiary designation, (ii) a will or (iii) the laws of descent and distribution, except as provided in the next
sentence. If the applicable Share Option Agreement so provides, a Nonstatutory Option shall also be transferable by gift or domestic relations order to a Family Member of the Optionee. An ISO may be exercised during the lifetime of the Optionee only
by the Optionee or by the Optionee’s guardian or legal representative. In addition, an Option shall comply with all conditions of Rule 12h-1(f)(1) under the Exchange Act until the Company becomes
subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act. Such conditions include, without limitation, the transferability restrictions set forth in Rule 12h-1(f)(1)(iv)
and (v) under the Exchange Act, which shall apply to an Option and, prior to exercise, to the Shares to be issued upon exercise of such Option during the period commencing on the Date of Grant and ending on the earlier of (i) the date when
the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act or (ii) the date when the Company makes a determination that it will cease to rely on the exemption afforded by Rule 12h-1(f)(1) under the Exchange Act. During such period, an Option and, prior to exercise, the Shares to be issued upon exercise of such Option shall be restricted as to any pledge, hypothecation or other
transfer by the Optionee, including any short position, any “put equivalent position” (as defined in Rule 16a-1(h) under the Exchange Act) or any “call equivalent position” (as defined
in Rule 16a-1(b) under the Exchange Act). 
 (j) No Rights as a Shareholder. An
Optionee, or a transferee of an Optionee, shall have no rights as a shareholder with respect to any Shares covered by the Optionee’s Option until such person becomes entitled to receive such Shares by filing a notice of exercise and paying the
Exercise Price pursuant to the terms of such Option. 
 (k) Modification, Extension and Assumption of Options. Within the limitations
of the Plan, the Board of Directors may modify, extend or assume outstanding Options or may accept the cancellation of outstanding Options (whether granted by the Company or another issuer) in return for the grant of new Options or a different type
of award for the same or a different number of Shares and at the same or a different Exercise Price (if applicable). The foregoing notwithstanding, no modification of an Option shall, without the consent of the Optionee, impair the Optionee’s
rights or increase the Optionee’s obligations under such Option. 

  
 E-5 













 (l) Company’s Right to Cancel Certain Options. Any other provision of the Plan
or a Share Option Agreement notwithstanding, the Company shall have the right at any time to cancel an Option that was not granted in compliance with Rule 701 under the Securities Act. Prior to canceling such Option, the Company shall give the
Optionee not less than 30 days’ notice in writing. If the Company elects to cancel such Option, it shall deliver to the Optionee consideration with an aggregate Fair Market Value equal to the excess of (i) the Fair Market Value of the
Shares subject to such Option as of the time of the cancellation over (ii) the Exercise Price of such Option. The consideration may be delivered in the form of cash or cash equivalents, in the form of Shares, or a combination of both. If the
consideration would be a negative amount, such Option may be cancelled without the delivery of any consideration. 
 SECTION 7. PAYMENT FOR SHARES.

 (a) General Rule. The entire Purchase Price or Exercise Price of Shares issued under the Plan shall be payable in cash or cash
equivalents at the time when such Shares are purchased, except as otherwise provided in this Section 7. In addition, the Board of Directors in its sole discretion may also permit payment through any of the methods described in (b) through
(g) below: 
 (b) Services Rendered. Shares may be awarded under the Plan in consideration of services rendered to the Company, a
Parent or a Subsidiary prior to the award provided that no Share is issued for less than its par value paid in cash to the Company. 

(c) Promissory Note. All or a portion of the Purchase Price or Exercise Price (as the case may be) of Shares issued under the Plan may
be paid with a full-recourse promissory note. The Shares shall be pledged as security for payment of the principal amount of the promissory note and interest thereon. The interest rate payable under the terms of the promissory note shall not be less
than the minimum rate (if any) required to avoid the imputation of additional interest under the Code. Subject to the foregoing, the Board of Directors (at its sole discretion) shall specify the term, interest rate, amortization requirements (if
any) and other provisions of such note. 
 (d) Surrender of Shares. All or any part of the Exercise Price may be paid by
surrendering, or attesting to the ownership of, Shares that are already owned by the Optionee. Such Shares shall be surrendered to the Company in good form for transfer and shall be valued at their Fair Market Value as of the date when the Option is
exercised. 
 (e) Exercise/Sale. If the Shares are publicly traded, all or part of the Exercise Price and any withholding taxes may
be paid by the delivery (on a form prescribed by the Company) of an irrevocable direction to a securities broker approved by the Company to sell Shares and to deliver all or part of the sales proceeds to the Company. 

  
 E-6 













 (f) Net Exercise. An Option may permit exercise through a “net
exercise” arrangement pursuant to which the Company will reduce the number of Shares issued upon exercise by the largest whole number of Shares having an aggregate Fair Market Value (determined by the Board of Directors as of the exercise date)
that does not exceed the aggregate Exercise Price or the sum of the aggregate Exercise Price plus all or a portion of the minimum amount required to be withheld under applicable tax law (with the Company accepting from the Optionee payment of cash
or cash equivalents to satisfy any remaining balance of the aggregate Exercise Price and, if applicable, any additional withholding obligation not satisfied through such reduction in Shares); provided that to the extent Shares subject to an
Option are withheld in this manner, the number of Shares subject to the Option following the net exercise will be reduced by the sum of the number of Shares withheld and the number of Shares delivered to the Optionee as a result of the exercise.

 (g) Other Forms of Payment. To the extent that an Award Agreement so provides, the Purchase Price or Exercise Price of Shares
issued under the Plan may be paid in any other form permitted by applicable laws. 
 SECTION 8. TERMS AND CONDITIONS OF RESTRICTED SHARE UNITS. 

(a) Restricted Share Unit Award Agreement 

Each Restricted Share Unit Award under the Plan shall be evidenced by a Restricted Share Unit Award Agreement between the Grantee and the
Company. The Restricted Share Unit Award shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions that are not inconsistent with the Plan and that the Board of Directors deems
appropriate for inclusion in a Restricted Share Unit Award Agreement. The provisions of the various Restricted Share Unit Award Agreements entered into under the Plan need not be identical. 

(b) Number of Shares 

Each Restricted Share Unit Award Agreement shall specify the number of Shares that are subject to the Restricted Share Unit Award and shall
provide for the adjustment of such number in accordance with Section 9. 
 (c) Vesting Conditions 

Each Restricted Share Unit Award may or may not be subject to vesting, as determined by the Board of Directors in its sole discretion. Vesting
shall occur, in full or in installments, upon satisfaction of the conditions specified in the Restricted Share Unit Award Agreement. A Restricted Share Unit Award Agreement may provide for accelerated vesting upon certain specified events. 

  
 E-7 













 (d) Voting Rights 

The holders of Restricted Share Unit Awards shall have no voting rights. 

(e) Settlement of Restricted Share Unit Awards 

Settlement of any vested Restricted Share Unit Award may be made in the form of (a) Shares, (b) cash or (c) any combination of both,
as determined by the Board of Directors in its sole discretion. The actual number of Restricted Share Units eligible for settlement may be larger or smaller than the number included in the original Restricted Share Unit Award, based on predetermined
performance factors. Methods of converting Restricted Share Units into cash may include (without limitation) a method based on the average Fair Market Value of a Share over a series of trading days. Vested Restricted Share Units shall be settled in
such manner and at such time(s) as specified in the Restricted Share Unit Award Agreement. Until a Restricted Share Unit Award is settled, the number of such Restricted Share Units shall be subject to adjustment pursuant to Section 9. 

(f) Modification or Assumption of Restricted Share Units 

Within the limitations of the Plan, the Board of Directors may modify or assume outstanding Restricted Share Units or may accept the
cancellation of outstanding Restricted Share Units (whether granted by the Company or by another issuer) in return for the grant of new Restricted Share Units for the same or a different number of Shares or in return for the grant of a different
type of Award. 
 SECTION 9. ADJUSTMENT OF SHARES. 

(a) General. In the event of a subdivision of the outstanding Shares, a declaration of a dividend payable in Shares, a combination or
consolidation of the outstanding Shares into a lesser number of Shares, a reclassification, or any other increase or decrease in the number of issued Shares effected without receipt of consideration by the Company, proportionate adjustments shall
automatically be made in each of (i) the number and kind of Shares available for future grants under Section 4, (ii) the number and kind of Shares covered by each outstanding Option and any outstanding and unexercised right to
purchase Shares that has not yet expired pursuant to Section 5(b), (iii) the Exercise Price under each outstanding Option and the Purchase Price applicable to any unexercised share purchase right described in clause (ii) above, (iv)
the number and kind of Shares covered by each outstanding Restricted Share Unit that has not yet expired and (v) any repurchase price that applies to Shares granted under the Plan pursuant to the terms of a Company repurchase right under the
applicable Award Agreement. In the event of a declaration of an extraordinary dividend payable in a form other than Shares in an amount that has a material effect on the Fair Market Value of the Shares, a recapitalization, a spin-off, or a similar occurrence, the Board of Directors at its sole discretion may make appropriate adjustments in one or more of the items listed in clauses (i) through (iv) above. No fractional Shares shall
be issued under the Plan as a result of an adjustment under this Section 9(a), although the Board of Directors in its sole discretion may make a cash payment in lieu of fractional Shares. 

  
 E-8 













 (b) Corporate Transactions. In the event that the Company is a party to a merger or
consolidation, or in the event of a sale of all or substantially all of the Company’s shares or assets, all Shares acquired under the Plan and all Options and other Plan awards outstanding on the effective date of the transaction shall be
treated in the manner described in the definitive transaction agreement (or, in the event the transaction does not entail a definitive agreement to which the Company is party, in the manner determined by the Board of Directors in its capacity as
administrator of the Plan, with such determination having final and binding effect on all parties), which agreement or determination need not treat all Options and awards (or all portions of an Option or an award) in an identical manner. The
treatment specified in the transaction agreement may include (without limitation) one or more of the following with respect to each outstanding Option or award: 

(i) Continuation of the Option or award by the Company (if the Company is the surviving company). 

(ii) Assumption of the Option by the surviving company or its parent in a manner that complies with Code Section 424(a)
(whether or not the Option is an ISO) and applicable foreign exchange and tax requirements. 
 (iii) Substitution by the
surviving company or its parent of a new option for the Option in a manner that complies with Code Section 424(a) (whether or not the Option is an ISO) and applicable foreign exchange and tax requirements. 

(iv) Cancellation of the Option and a payment to the Optionee with respect to each Share subject to the portion of the Option
that is vested as of the transaction date equal to the excess of (A) the value, as determined by the Board of Directors in its absolute discretion, of the property (including cash) received by the holder of a Share as a result of the
transaction, over (B) the per-Share Exercise Price of the Option (such excess, the “Spread”). Such payment shall be made in the form of cash, cash equivalents, or securities of the
surviving company or its parent having a value equal to the Spread. In addition, any escrow, holdback, earn-out or similar provisions in the transaction agreement may apply to such payment to the same
extent and in the same manner as such provisions apply to the holders of Shares. If the Spread applicable to an Option is zero or a negative number, then the Option may be cancelled without making a payment to the Optionee. 

  
 E-9 













 (v) Cancellation of the Option without the payment of any consideration;
provided that the Optionee shall be notified of such treatment and given an opportunity to exercise the Option (to the extent the Option is vested or becomes vested as of the effective date of the transaction) during a period of not less than five
(5) business days preceding the effective date of the transaction, unless (A) a shorter period is required to permit a timely closing of the transaction and (B) such shorter period still offers the Optionee a reasonable opportunity to
exercise the Option. Any exercise of the Option during such period may be contingent upon the closing of the transaction. 

(vi) Suspension of the Optionee’s right to exercise the Option during a limited period of time preceding the closing of
the transaction if such suspension is administratively necessary to permit the closing of the transaction. 
 (vii)
Termination of any right the Optionee has to exercise the Option prior to vesting in the Shares subject to the Option (i.e., “early exercise”), such that following the closing of the transaction the Option may only be exercised to the
extent it is vested. 
 For the avoidance of doubt, the Board of Directors has discretion to accelerate, in whole or part, the vesting and exercisability of
an Option or other Plan award, including the vesting and settlement of a Restricted Share Unit Award in connection with a corporate transaction covered by this Section 9(b). 

(c) Reservation of Rights. Except as provided in this Section 9, a Participant shall have no rights by reason of (i) any
subdivision or consolidation of shares of any class, (ii) the payment of any dividend or (iii) any other increase or decrease in the number of shares of any class. Any issuance by the Company of shares of any class, or securities
convertible into shares of any class, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number or Exercise Price of Shares subject to an Option. The grant of an Option pursuant to the Plan shall not affect in
any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes of its capital or business structure, to merge or consolidate or to dissolve, liquidate, sell or transfer all or any part of its business or
assets. 

  
 E-10 













 SECTION 10. PRE-EXERCISE INFORMATION REQUIREMENT. 

(a) Application of Requirement. This Section 10 shall apply only during a period that (i) commences when the Company
begins to rely on the exemption described in Rule 12h-1(f)(1) under the Exchange Act, as determined by the Company in its sole discretion, and (ii) ends on the earlier of (A) the date when the Company ceases to rely on such exemption,
as determined by the Company in its sole discretion, or (B) the date when the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act. In addition, this Section 10 shall in no event
apply to an Optionee after he or she has fully exercised all of his or her Options. 
 (b) Scope of Requirement. The Company
shall provide to each Optionee the information described in Rule 701(e)(3), (4) and (5) under the Securities Act. Such information shall be provided at six-month intervals, and the financial
statements included in such information shall not be more than 180 days old. The foregoing notwithstanding, the Company shall not be required to provide such information unless the Optionee has agreed in writing, on a form prescribed by the Company,
to keep such information confidential. 
 SECTION 11. MISCELLANEOUS PROVISIONS. 

(a) Securities Law Requirements. Shares shall not be issued under the Plan unless, in the opinion of counsel acceptable to the
Board of Directors, the issuance and delivery of such Shares comply with (or are exempt from) all applicable requirements of law, including (without limitation) the Securities Act, the rules and regulations promulgated thereunder, state securities
laws and regulations, and the regulations of any exchange or other securities market on which the Company’s securities may then be traded. The Company shall not be liable for a failure to issue Shares as a result of such requirements. 

(b) No Retention Rights. Nothing in the Plan or in any right or Option granted under the Plan shall confer upon the Participant
any right to continue in Service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Company (or any Parent or Subsidiary employing or retaining the Participant) or of the Participant, which
rights are hereby expressly reserved by each, to terminate his or her Service at any time and for any reason, with or without cause. 

(c) Treatment as Compensation. Any compensation that an individual earns or is deemed to earn under this Plan shall not be
considered a part of his or her compensation for purposes of calculating contributions, accruals or benefits under any other plan or program that is maintained or funded by the Company, a Parent or a Subsidiary. 

  
 E-11 













 (d) Governing Law. The Plan and all awards, sales and grants under the Plan shall be
governed by, and construed in accordance with, the laws of the Cayman Islands, as such laws are applied to contracts entered into and performed in such jurisdiction. 

(e) Conditions and Restrictions on Shares. Shares issued under the Plan shall be subject to such forfeiture conditions, rights of
repurchase, rights of first refusal, other transfer restrictions and such other terms and conditions as the Board of Directors may determine. Such conditions and restrictions shall be set forth in the applicable Award Agreement and shall apply in
addition to any restrictions that may apply to holders of Shares generally. In addition, Shares issued under the Plan shall be subject to conditions and restrictions imposed either by applicable law or by Company policy, as adopted from time to
time, designed to ensure compliance with applicable law or laws with which the Company determines in its sole discretion to comply including in order to maintain any statutory, regulatory or tax advantage. 

(f) Tax Matters. 

(i) As a condition to the award, grant, issuance, vesting, purchase, exercise or transfer of any award, or Shares issued
pursuant to any award, granted under this Plan, the Participant shall make such arrangements as the Board of Directors may require or permit for the satisfaction of any federal, state, local or foreign withholding tax obligations that may arise in
connection with such event. 
 (ii) Unless otherwise expressly set forth in an Award Agreement, it is intended that
awards granted under the Plan shall be exempt from Code Section 409A, and any ambiguity in the terms of an Award Agreement and the Plan shall be interpreted consistently with this intent. To the extent an award is not exempt from Code
Section 409A (any such award, a “409A Award”), any ambiguity in the terms of such award and the Plan shall be interpreted in a manner that to the maximum extent permissible supports the award’s compliance with the
requirements of that statute. Notwithstanding anything to the contrary permitted under the Plan, in no event shall a modification of an Award not already subject to Code Section 409A be given effect if such modification would cause the Award to
become subject to Code Section 409A unless the parties explicitly acknowledge and consent to the modification as one having that effect. A 409A Award shall be subject to such additional rules and requirements as specified by the Board of
Directors from time to time in order for it to comply with the requirements of Code Section 409A. In this regard, if any amount under a 409A Award is payable upon a “separation from service” to an individual who is considered a
“specified employee” (as each term is defined under Code Section 409A), then no such payment shall be made prior to the date that is the earlier of (i) six months and one day after the Participant’s separation from service
or (ii) the Participant’s death, but only to the extent such delay is necessary to prevent such payment from being subject to Section 409A(a)(1). In addition, if a transaction subject to Section 8(b) constitutes a payment event
with respect to any 409A Award, then the transaction with respect to such award must also constitute a “change in control event” as defined in Treasury Regulation Section 1.409A-3(i)(5) to the extent required by Code
Section 409A. 

  
 E-12 













 (iii) Neither the Company nor any member of the Board of Directors shall
have any liability to a Participant in the event an award held by the Participant fails to achieve its intended characterization under applicable tax law, or any payment cannot be made or is otherwise delayed due to applicable foreign exchange
restrictions. 
 (g) Languages. 

In case of any inconsistency between Chinese and English in this Plan, the English version shall prevail. 

SECTION 12. DURATION AND AMENDMENTS; SHAREHOLDER APPROVAL. 

(a) Term of the Plan. The Plan, as set forth herein, shall become effective on the date of its adoption by the Board of Directors,
subject to approval of the Company’s shareholders under Subsection (d) below. The Plan shall terminate automatically 10 years after the later of (i) the date when the Board of Directors adopted the Plan or (ii) the date when
the Board of Directors approved the most recent increase in the number of Shares reserved under Section 4 that was also approved by the Company’s shareholders. The Plan may be terminated on any earlier date pursuant to Subsection (b)
below. 
 (b) Right to Amend or Terminate the Plan. Subject to Subsection (d) below, the Board of Directors may amend, suspend
or terminate the Plan at any time and for any reason. 
 (c) Effect of Amendment or Termination. No Shares shall be issued or sold
and no Option or Restricted Share Unit Award shall be granted under the Plan after the termination thereof, except upon exercise of an Option (or any other right to purchase Shares) granted under the Plan prior to such termination. The termination
of the Plan, or any amendment thereof, shall not affect any Share or Restricted Share Unit Award previously issued or any Option previously granted under the Plan. 

  
 E-13
