Agreement, to have remained in possession of the Initial Leased Premises after the Tenant’s obligation to surrender the Initial Leased Premises shall have arisen and thereupon the Landlord shall have the right to exercise its remedies in
accordance with said subsection.

EXECUTIVE EMPLOYMENT AGREEMENT 

THIS EXECUTIVE EMPLOYMENT AGREEMENT (this “Agreement”) is made and entered into as of September 26, 2019 by and between
LianBio, an exempted company organized under the laws of the Cayman Islands (the “Company”), and Bing Li, an American citizen whose passport number is (the “Executive”). 

WHEREAS, the Company and the Executive desire to establish the terms and conditions of the Executive’s employment with the Company as
hereinafter set forth. 
 NOW, THEREFORE, in consideration of the mutual covenants and obligations hereinafter set forth, and for other good
and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
 1.
Employment. The Company hereby agrees to employ the Executive and the Executive hereby accepts employment with the Company upon the terms and conditions hereinafter set forth. 

2. Term. Subject to the provisions of Sections 7, 8, 9 and 10 hereof, the term of the Executive’s
employment with the Company will commence on October 1, 2019 (the “Commencement Date”) and end on the second (2nd) anniversary of the Commencement Date (the “Initial Term”). Unless earlier terminated by the
Company or the Executive in accordance with the terms and conditions set forth herein, the Executive’s employment by the Company hereunder shall automatically be renewed for subsequent one (1) year periods (each, a “Renewal
Term”). The term “Employment Period” shall mean the Initial Term and, if applicable, the Renewal Term or any shorter period resulting from any termination of service under Sections 7, 8, 9 and 10
hereof. 
 3. Duties and Responsibilities. The Executive will serve as the Chief Executive Officer (the “CEO”) of the
Company. The Executive will perform such duties and services as are customary for the position of CEO in privately-held enterprises similar to the Company and such other duties as may be reasonably assigned to him from time to time by the board of
directors of the Company (the “Board”). In furtherance of the foregoing, the Executive hereby agrees to perform faithfully such duties and responsibilities and the other reasonable duties and responsibilities assigned to him from
time to time by the Board. 
 4. Time to be Devoted to Service. Except for reasonable vacations, absences due to temporary illness,
and activities that may be mutually agreed to by the parties, the Executive shall devote his entire time, attention and energies during normal business hours and such evenings and weekends as may be reasonably required for the discharge of his
duties to the business of the Company while the Executive is employed by the Company during the Employment Period. During the Employment Period, the Executive will not be engaged in any other business activity that, in the reasonable judgment of the
Board, conflicts with the duties of the Executive hereunder (including without limitation, any activities that present a conflict of interest) without the prior written consent of the Company. 

5. Conflict of Interest. The Executive has reviewed with the Board (i) the present directorships and other positions or roles held
by the Executive or his associate(s) in all such business organizations or arrangements that may be directly competitive or directly in conflict with the Company and (ii) ownership interests (legal or beneficial, direct or indirect) in another
company held by the Executive or his associate(s), schedules of which are listed on Schedule 1 hereto. The Executive agrees to review with the Board any potential directorships, ownership (legal and beneficial, direct and indirect) interests
and other positions or roles with business organizations or arrangements that may be directly competitive or directly in conflict with the Company. Except as set forth in Schedule 1 hereto, the Executive or his associate(s) is precluded from
owning an interest (legal and beneficial, direct and indirect) in another company or serving as an employee, director, consultant, advisor or member of such other company that may be directly competitive or directly in conflict with the Company
until such interest is presented to the Board and the Board consents to such interest or employment. 

 6. Compensation; Benefits; Reimbursement. 

6.1 Base Salary. During the Employment Period, the Executive shall receive as compensation an initial annual base salary of US$550,000
(the “Base Salary”), less any payroll taxes or withholdings legally required or properly requested by the Executive. This Base Salary and all other compensation and reimbursement under the Agreement, may be provided through a human
resources service organization, and will be payable in such installments as are applicable to employees of the Company at substantially the same service level as the Executive. 

6.2 Stock Options. Subject to the Executive’s continued employment with the Company and the Executive’s execution and delivery
of Option Agreements in a form acceptable to the Company, the Company shall grant the Executive incentive stock options to purchase up to such number of ordinary shares of the Company as is equal to four percent (4%) of the Company as of immediately
following the consummation of the first preferred equity financing of the Company (the “Preferred Seed Closing”) (after giving effect to the Preferred Seed Closing), as follows: (i) following the Preferred Seed Closing, one-half (1/2) shall be granted at a price per share equal to the fair market value of such shares on the date of grant (as determined by the Board) (the “Initial Option Grant”) and
(ii) following the consummation of the first preferred equity financing of the Company occurring after the Preferred Seed Closing, the remaining one-half (1/2) shall be granted at a price per share equal
to the fair market value of such shares on the date of grant (as determined by the Board) (together with the Initial Option Grant, the “Options”). The Options shall be subject to the terms and conditions of a long-term incentive
plan to be adopted by the Company and approved by the Board, as amended from time to time (the “Plan”) and shLianall each vest as to one-third (1/3) immediately upon grant, another one-third (1/3) on the first anniversary of the Commencement Date and the final one-third (1/3) on the second anniversary of the Commencement Date.    The
Executive may, from time to time, be entitled to receive additional options to purchase ordinary shares of the Company or its affiliates and other equity-based incentives (including by way of participation in the Plan) as and when determined by the
Board, in its sole and exclusive discretion. 
 6.3 Bonus. At the conclusion of each calendar year during the Employment Period, the
Executive may be entitled to receive a performance-based annual bonus with a target equal to 110% of the Base Salary (the “Performance Bonus”), the actual amount of which shall be determined by the Board in its sole and exclusive
discretion based on the Board’s evaluation of the Executive’s performance in such calendar year and achievements of goals established annually by the Board after consultation with the Executive. The Executive is eligible to receive an
additional annual cash bonus in excess of the Performance Bonus, the amount of which shall be determined by the Board, in its sole and exclusive discretion. 

6.4 Fringe Benefits. During the Employment Period, the Executive will be entitled to the fringe benefits that are made available to
officers of the Company and such other benefits as are determined by the Board, in its sole and exclusive discretion. In addition, the Executive will be entitled to the specific benefits listed in Schedule 2 attached hereto. 

6.5 Reimbursements. During the Employment Period, the Executive will be reimbursed, in accordance with the Company’s expense
reimbursement policy as in effect from time to time, for all reasonable traveling expenses and other disbursements incurred by him for or on behalf of the Company in the performance of his duties hereunder upon presentation by the Executive of
appropriate vouchers. 

  
 2 

 6.6 Deductions. Recognizing that the Executive is an employee for all purposes, the
Company or a subsidiary of the Company shall deduct from any compensation payable to the Executive the sums which the Company or such subsidiary is required by law to deduct, including, but not limited to, government state withholding taxes, social
security taxes and state disability insurance and mandatory provident funds, and the Company or such subsidiary shall pay any amounts so deducted to the applicable governmental entities and agents entitled to receive such payments. 

7. Involuntary Termination. 

7.1 Disability. If the Executive dies, then the Executive’s employment by the Company hereunder shall automatically terminate on
the date of the Executive’s death. If the Executive is incapacitated or disabled by accident, sickness or otherwise so as to render him mentally or physically incapable of performing the services required to be performed by him under this
Agreement for a period of ninety (90) consecutive days or longer, or for ninety (90) days during any six (6) month period (such condition being herein referred to as “Disability”), the Company, at its option, may
terminate the Executive’s employment under this Agreement immediately upon giving him notice to that effect. In the case of a Disability, until the Company shall have terminated the Executive’s service in accordance with the foregoing, the
Executive will be entitled to receive compensation, at the rate and in the manner provided in Section 6, notwithstanding any such physical or mental disability. Termination pursuant to this
Section 7 is hereinafter referred to as an “Involuntary Termination”. 
 7.2 Substitution.
The Board may designate another employee to act in the Executive’s place during any period of Disability suffered by the Executive during the Employment Period. Notwithstanding any such designation, the Executive shall continue to receive the
Executive’s Base Salary and benefits in accordance with Section 6 of this Agreement until the Executive becomes eligible for disability income under the Company’s disability income insurance (if any) or until the
termination of the Executive’s employment, whichever shall first occur. 
 7.3 Disability Income Payments. While receiving
disability income payments under the Company’s disability income insurance (if any), the Executive shall not be entitled to receive any Base Salary under Section 6.1, but shall continue to participate in all other
compensation and benefits in accordance with Section 6.4 until the date of the Executive’s termination of employment. 

7.4 Verification of Disability. If any question shall arise as to whether during any period the Executive is disabled through any
illness, injury, accident or condition of either a physical or psychological nature so as to be unable to perform substantially all of the Executive’s duties and responsibilities hereunder, the Executive may, and at the request of the Company
shall, submit to a medical examination by a physician selected by the Company to whom the Executive or the Executive’s guardian has no reasonable objection to determine whether the Executive is so disabled and such determination shall for the

For purposes of this Agreement, “Change in Control” means the occurrence of any of the following: 

 

	 	(i)	 any one person, or more than one person acting as a group (“Person”), acquires ownership of
the stock of the Company that, together with the stock held by such Person, constitutes more than 50% of the total voting power of the stock of the Company, except that any change in the ownership of the stock of the Company as a result of a private
financing of the Company that is approved by the Board will not be considered a Change in Control; or 

  

	 	(ii)	 the sale of all or substantially all assets of the Company. 

For purposes of this definition, Persons will be considered to be acting as a group if they are owners of a corporation that enters into a merger,
consolidation, purchase or acquisition of stock, or similar business transaction with the Company. Further and for the avoidance of doubt, a transaction will not constitute a Change in Control if: (i) its sole purpose is to re-domicile the Company in a jurisdiction other than its original jurisdiction of incorporation, or (ii) its sole purpose is to create a holding company that will be owned in substantially the same proportions
by the persons who held the Company’s securities immediately before such transaction. With regard to any payment considered to be nonqualified deferred compensation under Section 409A (as defined below), to the extent applicable, that is
payable upon a Change in Control, to avoid the imposition of an additional tax, interest or penalty under Section 409A of the Internal Revenue Code of 1986, as amended, no amount will be payable unless such change in control constitutes a
“change in control event” within the meaning of Section 1.409A-3(i)(5) of the Treasury Regulations. 

11.5 Release. The parties acknowledge and agree that damages which will result to the Executive for Termination without Cause by the
Company or other breach of this Agreement by the Company shall be extremely difficult or impossible to establish or prove, and agree that the Severance Payment shall constitute liquidated damages for any breach of this Agreement by the Company
through the date of termination. The Executive agrees that, except for such other payments and benefits to which the Executive may be entitled as expressly provided by the terms of this Agreement or any applicable benefit plan, such liquidated
damages shall be in lieu of all other claims that the Executive may make by reason of termination of his employment or any such breach of this Agreement and that, as a condition to receiving the Severance Payment, the Executive will execute a
release of claims in a form reasonably satisfactory to the Company. 
 12. Indemnification of Executive.

Executive provides the Company with a written undertaking to repay the amount of Indemnifiable Amounts if it is finally determined by a court of competent jurisdiction that the Executive is not entitled under this Agreement to indemnification with
respect to such Indemnifiable Amounts. 
 12.3 Limitation on Indemnification. The Executive shall not be entitled to any
indemnification under this Section 12 if the Executive knowingly violated any duty, responsibility or obligation of the Executive imposed under this Agreement, the Compliance Agreement or any Company policy.

indemnification or advancement of expenses than is provided under this Agreement, the Executive shall be entitled to such broader indemnification and advancements, and this Agreement shall be deemed to be amended to such extent.
