 2. LICENSE GRANTS, OWNERSHIP. 

2.1 License Grant. 
 2.1.1
Subject to the terms and conditions of this Agreement, Tarsus grants to Lian (a) an exclusive license under the Licensed Know-How and, and to the extent held in the Territory, the Licensed Patents, to
Develop, Commercialize, make (in accordance with Article 7), have made (in accordance with Article 7), use, offer for sale, sell and import Licensed Products in the Field and in the Territory only for sale and use in the Field and in the Territory;
and (b) a non-exclusive license, under the Licensed IP, to make (in accordance with Article 7) and have made (in accordance with Article 7), but not to Commercialize, the Licensed Products outside the
Territory for exploitation in the Field and in the Territory ((a) and (b), collectively, the “License”). The License shall be non-transferable (except as expressly set forth in
Section 17.10). Lian shall not (and shall not permit its Affiliates or any Sublicensees to) Develop or Commercialize Licensed Products outside the Field or outside the Territory. 

2.1.2 The exclusivity granted under the License under Licensed Know-How in Section 2.1.1(a) means
only that: [***]. 
 2.1.3 For clarity: (a) if Licensed Know-How relates to both the Compound
and any other active therapeutic ingredient, then the License granted to Lian with respect to the Licensed Know-How excludes any right with respect to any other active therapeutic ingredient; and (b) if
any Licensed Patent Covers both the Compound (or any use thereof) and any other active therapeutic ingredient (or any use thereof), then the License granted to Lian with respect to such Licensed Patent excludes any right with respect to such other
active therapeutic ingredient (or any use thereof). 
 2.2 Field. Lian may, in its sole discretion, exclude Meibomian Gland Disease
from the Field by notifying Tarsus of such exclusion prior to the Indication Decision Date (“Exclusion Indication Notice”). For clarity, Lian cannot exclude Meibomian Gland Disease from the Field after the Indication Decision
Date. If Lian provides the Exclusion Indication Notice prior to the Indication Decision Date, then for all purposes of this Agreement, (including the License and the definition of Competing Product), the Field shall exclude the treatment of
Meibomian Gland Disease. This exclusion shall be permanent and apply on a prospective basis after Tarsus’s receipt of the corresponding Exclusion Indication Notice. 

2.3 Sublicenses. Lian shall have the right to grant sublicenses of the rights granted to Lian under the License to its Affiliates or
Third Parties without consent of Tarsus; provided that (a) each such sublicense is subordinate to and consistent with the terms and conditions of this Agreement, and (b) each Sublicensee agrees to be bound by all terms of this Agreement
applicable to such Sublicensee in the same manner as Lian is bound (including, to the extent applicable, Sections 2.3, 2.5, 2.6, 2.7, 3.1, 4.3, 5.2, 5.6, 7.1 (the last sentence), 9.10, 13.1, 14.2.1, and 14.2.5, and Articles 6, 8, 10, and 15). Lian
shall remain responsible for its Affiliates’ and each Sublicensee’s compliance with all obligations under this Agreement applicable to such Affiliates or Sublicensees. Upon the termination of this Agreement, at the written request of any
Sublicensee who is not then in breach of its sublicense agreement, Tarsus will discuss in good faith with such Sublicensee whether to enter into a direct license agreement with such Sublicensee. No grant of any sublicense to a Third Party or any
Lian Affiliate shall relieve Lian of its obligations hereunder. 

  
 12 













 2.4 Transfer of Licensed Know-How. Promptly
following the Effective Date, Tarsus shall provide to Lian copies of all material Licensed Know-How (other than Manufacturing Technology), including documentation and reports within the Licensed Know-How from Clinical Trials and preclinical studies for the Licensed Product that have been obtained by Tarsus, and any other Licensed Know-How reasonably requested by Lian.
Upon Lian’s request (no more than once in any [***] period), Tarsus shall provide to Lian the Licensed Know-How (other than Manufacturing Technology) reasonably requested by Lian that has not previously
been provided to Lian hereunder. 
 2.5 Approval of Licensed Product. Lian shall not Develop, Commercialize, make, have made, use,
offer for sale, sell, market, promote or import any Licensed Product (including, any combination thereof) other than those Licensed Products (including, any combination thereof) approved by Tarsus in writing, such approval not to be unreasonably
withheld. For clarity, the foregoing restriction on Lian and approval rights of Tarsus apply to the Develop, Commercialize, making, having made, use, offering to sell, selling, marketing, promoting and importing of any combination of a Licensed
Product and any other product. Without limiting the reasons that Tarsus may withhold approval, if Lian proposes to Develop, Commercialize, make, have made, use, offer to sell, sell, market, promote, or import a Licensed Product as (or as part of)
such combination, then it will be deemed reasonable for Tarsus to withhold its approval of such Licensed Product or combination thereof if: (a) Tarsus uses reasonable efforts to negotiate with Elanco to add customary allocations for combination
products in the definition of net sales in the Elanco Agreement with respect to such Licensed Product or combination thereof; (b) Elanco does not agreed to such additions; and (c) Lian does not agree to waive the application of the
customary allocations for Combination Products in the definition of Net Sales for such Licensed Product or combination thereof. 
 2.6
Elanco Agreement. The License shall be subject to the terms under the Elanco Agreement set forth on Schedule 2.6; provided that Tarsus shall be responsible for any and all amounts payable to Elanco under the Elanco Agreement resulting from
the execution of, and activities of Lian in the Field and in the Territory under, this Agreement or any Supply Agreement. 
 2.7
Inventions. Ownership of intellectual property first discovered, or invented through the activities of one or more Parties in the performance of activities (including, all Development and manufacturing of the Licensed Product conducted by or
for Lian, its Affiliates or any Sublicensees) under this Agreement (“Inventions”) will follow inventorship as determined in accordance with United States patent laws for determining inventorship, irrespective of whether such
intellectual property is patentable or incorporated into a patent application. Lian and its Affiliates hereby grants to Tarsus a non-exclusive, sublicenseable (through multiple tiers), royalty-free, fully paid-up, transferable, perpetual license, under any Inventions (and all Intellectual Property Rights therein) created by or on behalf of Lian, its Affiliates, or any Sublicensees, to Develop, manufacture, or
Commercialize the Compound or any product containing the Compound; provided, however, that such license does not include the right to, sell and have sold Licensed Products in the Territory until after the effective date of termination or expiration
of this Agreement. Lian shall not (and shall ensure that neither its Affiliates nor any Sublicensees) license any Invention to any Third Party with respect to any Competing Product. 

2.8 Trademark. Lian may brand the Licensed Products in the Territory using a trade name that Tarsus selects to brand the Licensed
Products outside of the Territory (the “Tarsus Global Licensed Product Trademark”). If Lian elects to market the Licensed Products within the Territory under a separate brand name than the Tarsus Global Licensed Product
Trademark (including a localized version of the Tarsus Global Licensed Product Trademark), then Lian shall provide such alternative brand name for the Licensed Products within the Territory to the JSC for review and approval. 

2.9 No Implied Rights; Retained Rights. Nothing contained in this Agreement confers or will be construed to confer any rights by
implication, estoppel or otherwise under any Intellectual Property Rights, other than the rights expressly granted in this Agreement. All rights not expressly granted by a Party under this Agreement are reserved to such Party. Notwithstanding
anything to the contrary set forth in this 

  
 13 













 
Agreement, Lian’s License under (and any exclusivity with respect to) Licensed Know-How shall not in any way restrict Tarsus and its Affiliates from
(a) using, disclosing to any Third Party, or granting any Third Party the right to use Licensed Know-How for any purpose other than to Develop, Commercialize, make, have made, use, offer for sale, sell
and import the Licensed Products in the Field and in the Territory for sale and use in the Field and in the Territory, or (b) performing Tarsus’s obligations or exercising Tarsus’s rights under this Agreement. 

3. EXCLUSIVITY. 
 3.1
Exclusivity. During the Term, except for the Compound and Licensed Products being Developed, manufactured, or Commercialized by Lian, Lian Affiliates, and Sublicensees, neither Tarsus or its Affiliates, nor Lian or its Affiliates will (by
itself or with or through an Affiliate or a Third Party, directly or indirectly) Develop, make, have made, use, sell, offer for sale, import, or Commercialize in the Territory any Competing Product. For all purposes of this Section 3.1,
Affiliates of a Party shall not be deemed to include (and the foregoing shall not restrict) an Acquiring Organization after an Acquisition of such Party. The foregoing does not restrict Tarsus, or any of its Affiliates, or any of its or their
sublicensees from making (or having made) a Licensed Product in the Territory solely for use outside the Territory. 
 3.2 Acquisition of
Lian. Tarsus may terminate this Agreement immediately upon notice to Lian at any time after (i) an Acquisition of Lian Ophthalmology or Lian that includes the assets relating to this Agreement (including an Acquisition of LianBio), or
(ii) the sale of all or substantially all the assets relating to this Agreement in a transaction or series of related transactions, if both: 

[***]. 
 3.3 Acquisition of
Tarsus. After (a) an Acquisition of Tarsus, or (b) the sale of all or substantially all the assets of Tarsus relating to this Agreement in a transaction or series of related transactions, in either case ((a) or (b)), Lian may reduce
its obligation to pay Tarsus future royalties on Net Sales of Licensed Products in the Territory to the amount of the royalty Tarsus must pay Elanco under the Elanco Agreement for such Net Sales (if any) if the Acquiring Organization of Tarsus under
sub-clause (a), or the purchaser of the applicable assets under sub-clause (b), at any time after [***] days following the closing of such transaction Commercially Sells
a Competing Product for the treatment of Demodex Blepharitis in the Territory (an “Acquiring Organization Competing Product Reduction” for the Territory). The foregoing Acquiring Organization Competing Product Reduction shall
only apply with respect to Calendar Quarters in which the Acquiring Organization of Tarsus under sub-clause (a) or the purchaser of the applicable assets under
sub-clause (b) Commercially Sells a Competing Product in the Territory. For clarity, Lian may not reduce any royalties in any Calendar Quarter in which the Acquiring Organization does not Commercially
Sell a Competing Product in the Territory. Additionally, Net Sales in each Calendar Quarter for which an Acquiring Organization Competing Product Reduction applies shall not be counted for the purposes of determining whether Lian must pay Tarsus
further Commercial Milestone Payments (defined in Section 9.4.1). However, if Lian makes an Acquiring Organization Competing Product Reduction in the Territory, then, for each Calendar Year in which (i) Lian does not pay Tarsus a
Commercial Milestone Payment, (ii) Tarsus is required under the Elanco Agreement to pay Elanco a milestone payment based on Net Sales of products in a Calendar Year, and (iii) Tarsus would not have been required to pay such milestone
payment in such Calendar Year if not for the sales of Licensed Products by Lian, Lian Affiliates, and Sublicensees in the Territory in such Calendar Year, Lian shall pay Tarsus an amount equal to the product of such milestone payment to Elanco
multiplied by the fraction A/B, where “A” is the Net Sales of Lian, Lian Affiliates, and Sublicensees of Licensed Products in the Territory in such Calendar Year, and “B” is the total worldwide net sales of products counted
towards such milestone payment to Elanco in such Calendar Year.

 4. JOINT STEERING COMMITTEE. 

4.1 General. Within [***] days after the Effective Date, the Parties shall establish a joint steering committee (the “Joint
Steering Committee” or “JSC”) consisting of two (2) representatives from each Party. Each Party’s representatives on the JSC shall be of the seniority, experience, and decision-making authority
appropriate in light of the functions, responsibilities and authority of the JSC. Each Party may replace its representatives on the JSC at any time by providing notice in writing to the other Party. If agreed by the Parties, the JSC may form
subcommittees or working groups as may be necessary or desirable to facilitate the activities under this Agreement. The JSC shall serve as a forum for communication with regards to (a) the overall state of the alliance, (b) progress of
Lian’s and Tarsus’s Development and Commercialization activities for the Licensed Products in their respective territories; (c) overseeing, guiding, and monitoring the Development (including the conducting of Clinical Trials) and
Regulatory Approval efforts by Lian for the Licensed Products in the Field in the Territory by (i) reviewing and discussing the progress of the Development Activities, including any significant difficulties encountered or anticipated to be
encountered in connection therewith, and (ii) reviewing and approving any amendments to the then-current Development Plan; (d) reviewing the Commercialization Plan and updates thereto; and (e) Eligible Global Studies. 

4.2 JSC Decision-Making. The Parties acknowledge that one goal of the JSC’s efforts will be to harmonize Development and
Commercialization of the Licensed Products in the Territory with the Development and Commercialization of the same or other Licensed Products outside the Territory in the Field. The JSC shall meet on a [***] basis. JSC decisions shall be made by
consensus, with each Party having a single vote regardless of the number of the representatives of such Party. Any disputes among representatives at the JSC will be resolved by escalation to appropriate Senior Officers of Lian and Tarsus. To the
extent the Senior Officers cannot reach agreement on the matter at hand within [***] days after the dispute matter is brought to them, then the following will apply: 

4.2.1 Subject to Section 2.5 and except with respect to Tarsus’s exercise of its retained rights to make and have made Licensed
Products inside the Territory for exploitation outside the Territory or Field, Lian shall have final decision-making authority with respect to: (a) [***], and (b) [***], except (in each case of sub-clause
(a) and (b)) for any matter covered under Section 4.2.2 or Section 4.2.3 below. 
 4.2.2 Tarsus shall have final
decision-making authority with respect to: (a) [***], and (b) [***]. 
 4.2.3 Notwithstanding anything to the contrary, and except with
respect to Lian’s exercise of its rights under sub-clause (b) of Section 2.1.1, Tarsus shall have final decision-making authority over all (and neither the JSC nor Lian shall have any authority
regarding any) matters relating to the Development, Commercialization or other exploitation of the Compound, Licensed Products, or other products containing a Compound outside the Territory. 

4.3 Licensed Product Development. 

4.3.1 Lian shall: (a) notify Tarsus prior to preparing the first draft of any protocol for a Clinical Trial involving a Licensed Product;
(b) provide Tarsus with copies of each proposed protocol for such Clinical Trial; and (c) consider Tarsus’s comments with respect to such Clinical Trial. 

4.3.2 Without the approval of the JSC, Lian shall not undertake any Development efforts (including conducting any preclinical studies or
Clinical Trials) that are inconsistent with the then-current Development Plan, as approved by the JSC, for any Licensed Product.

5.3.1 Lian may extend the [***] Milestone by an additional [***] months by paying Tarsus USD $[***] . Such payment shall
be credited against the amount payable for Development Milestone Payment (iv) set forth in Section 9.4.1 if such Development Milestone Payment becomes due. 

5.3.2 Lian may extend the [***] Milestone by an additional [***] months by paying Tarsus USD $[***] . Such payment shall
be credited against the amount payable for Development Milestone Payment (v) set forth in Section 9.4.1 if such Development Milestone payment becomes due. 

5.4 Tarsus Development. Tarsus will use Commercially Reasonable Efforts to complete the Saturn-1
Clinical Trial and Saturn-2 Clinical Trial. An initial plan for Tarsus’s Development activities to be conducted outside of the Territory, including the Saturn-1
Clinical Trial and Saturn-2 Clinical Trial, is attached hereto as Exhibit B (the “Tarsus Development Plan”). 

5.5 Global Study Notice. At each quarterly meeting of the JSC prior to receipt of the first Regulatory Approval of a Licensed Product in
the Field in the Territory, Tarsus will communicate to Lian any Eligible Global Study that Tarsus is then planning to conduct or has conducted in the past quarter. If it is reasonably possible for Lian to participate in such Eligible Global Study,
then Lian may, in its sole discretion, provide Tarsus with a plan for its potential participation in such Eligible Global Study, including its share of all costs and expenses of such Eligible Global Study that directly relate to the Territory and
the proposed Regions (and sub-regions) in the Territory where the clinical sites for such Eligible Global Study will be located (the “Eligible Global Study Proposal”). Tarsus will
consider the Eligible Global Study Proposal in good faith. Notwithstanding the foregoing, Tarsus has no obligation to involve Lian in any Eligible Global Study in any way, and may (a) commence any Eligible Global Study at any time in its sole
discretion, or (b) include or exclude Lian from such Eligible Global Study in its sole discretion. 
 5.6 Reports and Records.

 5.6.1 Lian shall keep Tarsus informed of its activities under the Development Plan through summary updates to be provided to the JSC at
each regularly-scheduled meeting of the JSC. Tarsus shall keep Lian informed of its ongoing material Development activities under the Tarsus Development Plan through summary updates to be provided to the JSC at each regularly-scheduled JSC meeting.


  
 16 













 5.6.2 During the Term and for [***] years thereafter, Lian shall maintain records of
all Development Activities (or cause such records to be maintained) in sufficient detail and in good scientific manner as will properly reflect all work done and results achieved by or on behalf of Lian in the performance of the Development Plan or
otherwise in connection with Development Activities. Tarsus and Lian will provide each other with all reports, records, data and other information that result from Development Activities conducted by it, its respective Affiliates or any Sublicensees
in its respective territory. 
 6. COMMERCIALIZATION. 

6.1 Commercialization Plan. No later than [***] months prior to Lian’s estimated date of Regulatory Approval in the
Territory, Lian shall provide Tarsus with a written plan for the Commercialization of Licensed Products in the Field in the Territory (the “Commercialization Plan”), including a corresponding budget, which shall include
reasonable detail regarding the activities Lian expects to undertake, and the amounts it expects to expend in connection with such activities, in each case, over the [***] year period immediately following receipt of the first Regulatory Approval in
the Territory. The Commercialization Plan shall be updated annually. Lian shall provide the JSC with a reasonable opportunity to review and comments on the initial Commercialization Plan and each update thereto, and Lian shall consider all such
comments in good faith. Lian shall have the sole control over and decision-making authority with respect to the Commercialization of the Licensed Products in the Field in the Territory in accordance with the Commercialization Plan and otherwise as
expressly provided under this Agreement. 
 6.2 Diligence. Lian shall use Commercially Reasonable Efforts to Commercialize Licensed
Products in the Territory (and in particular, in the PRC) after achieving Regulatory Approval therefor. 
 6.3 Progress Report. On a
Licensed Product-by-Licensed Product basis for each of Meibomian Gland Disease and Demodex Blepharitis, following the receipt of Regulatory Approval in a Region in the
Territory, Lian shall provide to the JSC at each of its regularly-scheduled meetings during such period a written report summarizing Lian’s progress in the Commercialization of such Licensed Product in such Region for the relevant indication or
otherwise in the Field. 
 6.4 Samples and Labeling. 

6.4.1 Markings. Lian shall, and shall require its Affiliates and any Sublicensees to, mark all Licensed Products and all associated
packaging and documentation with the appropriate marking and notices associated with the applicable Licensed Patents in accordance with the applicable Laws of each country or jurisdiction in which such Licensed Products are manufactured, used or
sold. 
 6.4.2 Statements Consistent with Labeling. Lian shall ensure that its employees, independent contractors and other agents
market and sell Licensed Products consistent with the requirements of all applicable Laws in the applicable Region in the Territory. Lian shall ensure that all Licensed Products are labeled and distributed in accordance with applicable Law in the
applicable Region in the Territory. 

  
 17 













 6.5 Two-Invoice Policy. The Parties agree
that in the event that Tarsus is the holder of the Regulatory Approval for a Licensed Product in the PRC and, under the Two-Invoice Policy and tendering policies and applicable Laws in a given province in the
PRC, neither Lian nor any of its Affiliates can, based on their existing qualifications, distribute the Licensed Products for such province directly or indirectly to its distributors for the PRC, then Tarsus and Lian will use reasonable efforts to
discuss in good faith and agree to alternative arrangements for the distribution of the Licensed Product in such province that complies with the Two-Invoice Policy as implemented in such province and that
maintains the economic interests of Tarsus and Lian as agreed under this Agreement. 
 7. MANUFACTURING; TECHNOLOGY TRANSFER. 

7.1 Generally. Tarsus (itself or through designees) will supply Licensed Products to Lian for Development and Commercialization purposes
in the Field in the Territory, in each case, in accordance with separate written agreements, one for supply in Clinical Trials (“Clinical Supply Agreement”), and another for supply for Commercialization (the
“Commercial Supply Agreement”), each to be negotiated in good faith between the Parties pursuant to Section 7.2. For clarity, Lian shall not (and has no right under the License to) manufacture the Licensed Product,
except in accordance with Section 7.3. 
 7.2 Supply by Tarsus. The Parties shall negotiate in good faith to execute a Clinical
Supply Agreement and a Commercial Supply Agreement (and, in each case, related quality agreements), pursuant to which Lian will source the Licensed Product from Tarsus and Tarsus will supply (or cause a CMO designated by Tarsus supply) to Lian
Licensed Products for Lian’s exercise of the rights and licenses in accordance herewith including the conduct of Clinical Trials and Commercialize the Licensed Products in the Field and in the Territory. The Parties will commence negotiations
for a Clinical Supply Agreement after Tarsus enters into all agreements with Elanco and other suppliers necessary for the supply of filled, finished and unlabeled Licensed Product to Tarsus. The Parties expect to execute such Clinical Supply
Agreement within [***] days after Tarsus enters all of such necessary agreements but neither Party shall be deemed in breach of this Agreement for failing to do so. If, after negotiating in good faith, the Parties fail to execute such
Clinical Supply Agreement prior to the expiration of such [***] day period and an Acquisition of Tarsus has occurred during the Term prior to the expiration of such [***] day period or, after such period, an Acquisition of Tarsus
occurs prior to the execution of a Clinical Supply Agreement, then Lian may initiate a manufacturing technology transfer pursuant to Section 7.3.1 (a “Supply Agreement Negotiation Failure”). If, as a result of a Supply
Agreement Negotiation Failure, Tarsus fails to supply, or cause to be supplied, Licensed Products to Lian for Development purposes and as a direct result of such failure to supply Lian is not able to achieve the Phase III Milestone by the applicable
Completion Date, then such Completion Date will be extended by the number of days from the expiration of such [***] day period until such time as Tarsus is able to supply, or cause to be supplied, Licensed Products to Lian. The Clinical Supply
Agreement shall include (i) payment by Lian to Tarsus of an amount equal to Tarsus’s fully burdened cost in supplying the Licensed Product for clinical use plus [***] thereof, (ii) supply of sufficient quantities of the
Licensed Products to enable the conduct of Clinical Trials of the Licensed Product in the Field and in each Region of the Territory, as provided by the Development Plan; and (iii) other terms customary in the pharmaceutical industry to
agreements of this nature. The Commercial Supply Agreement shall include: (A) payment by Lian to Tarsus of an amount equal to Tarsus’s (either directly or through its CMO) fully burdened cost in supplying the Licensed Product for
commercial use plus [***] thereof, and (B) other terms customary in the pharmaceutical industry to agreements of this nature between collaboration partners. Notwithstanding the foregoing, Tarsus shall have no obligation to supply (or
cause supply of) Licensed Products for commercial use if both: (1) such supply could conflict with Tarsus’s own Development or Commercialization requirements for Licensed Products in any Calendar Year; and (2) Tarsus provides Lian
with at least [***] of the volume of Licensed Product that Tarsus procures for itself in such Calendar Year, and in such circumstance, Tarsus’s obligation to supply Licensed Product to Lian for such Calendar Year will be capped at
such [***] of the total volume of Licensed Product procured by Tarsus in such Calendar Year. 

  
 18 













 7.3 Manufacturing by Lian; Technology Transfer. 

7.3.1 After Tarsus receives Regulatory Approval from the FDA to market a Licensed Product in the Field, if (a) (i) a Supply Agreement
Negotiation Failure occurs, (ii) Tarsus has Materially Failed to Supply Licensed Products, or (iii) Lian has provided firm written purchase orders, or has provided a forecast that would be reasonably anticipated to, reach or exceed the cap
on supply of Licensed Products in a given Calendar Year set forth in sub-clauses (1) and (2) of Section 7.2), (b) Lian otherwise requests and Tarsus approves, not to be unreasonably withheld, or
(c) Tarsus so requests, then in each case ((a) - (c)), Lian will have the right and the obligation to manufacture or have manufactured the Licensed Product (but not the Compound) for the Territory for the supply needs of Lian, its Affiliates,
and its Sublicensees and distributors in the Field and in the Territory (the commencement of the manufacturing transfer process following the occurrence of either (a), (b), or (c), as applicable, the “Manufacturing Transfer
Commencement”). Notwithstanding anything to the contrary, Tarsus will have no obligation to continue supplying Lian with Licensed Product after a reasonable transition period (not to exceed [***] months, the
“Transition Period”) after Manufacturing Transfer Commencement. 
 7.3.2 During the Transition Period, at
Lian’s request and sole cost and expense, Tarsus will provide (or cause its designee to provide) to Lian the Manufacturing Technology and transition services necessary to enable Lian (or a CMO designated by Lian) to Manufacture clinical and
commercial supplies of the Licensed Product. 
 7.3.3 In each agreement with a CMO, Lian shall use reasonable efforts to obtain the
following: (a) a right for Tarsus to inspect and audit the CMO directly for quality control/assurance; and (b) a right for Tarsus to observe the CMO during the manufacturing of the Licensed Product, in each of (a) and (b), at
Tarsus’s cost and expense. At Tarsus’s request, Lian shall use reasonable efforts, at Tarsus’s cost and expense, to facilitate any inspection or audit of a CMO and permit Tarsus to observe the CMO during the manufacturing of the
Licensed Product. 
 7.3.4 Lian acknowledges that Tarsus’s obligations in Sections 7.3.1 and 7.3.2 are conditioned on Lian providing
certain documentation reasonably necessary to enable Tarsus to perform its obligations and Lian agrees to provide Tarsus with such documentation and otherwise reasonably cooperate with Tarsus in the performance of its obligations under this
Section 7.3. 
 7.4 Interim Supply. Until Tarsus and Lian execute a Clinical Supply Agreement, as reasonably requested by Lian
(and subject to Section 7.2), Tarsus shall place orders with its suppliers for the same Licensed Products for Development purposes on the same terms that Tarsus procures from such suppliers for its own account. Lian shall pay Tarsus an amount
equal to the Fully Burdened Manufacturing Cost of such Licensed Products ordered for Lian plus an additional [***] thereof. After delivery, Tarsus shall invoice Lian for the Fully Burdened Manufacturing Costs of such Licensed Product plus
[***] for the applicable order and Lian shall pay Tarsus within [***] days after receipt of such invoice. [***]. 
 8.
REGULATORY MATTERS. 
 8.1 Responsibility. Lian or its relevant Affiliates or Sublicensees shall be the exclusive holder and
owner of all Regulatory Approvals in the Territory for Licensed Products in the Field during the Term, and shall have the sole and exclusive right to make all Regulatory Filings with respect to all of the foregoing; provided, however, that if
applicable Laws or Regulatory Authorities in a Region in the Territory require any Regulatory Filings or Regulatory Approvals for Licensed Products in the Field to be filed in the name of and owned by Tarsus, then Tarsus will and hereby does
designate Lian (or a Lian Affiliate, Sublicensee, or a regulatory services contractor agent of Lian that agrees, for Tarsus’s benefit, to be bound by all obligations of this Agreement to which Lian is bound with respect to obtaining and
maintaining Regulatory Approvals, including, without limitation, all obligations of Lian pursuant to this Article 8 (a “Qualified Regulatory Agent”)) to be its sole authorized agent in such Region in the Territory for
obtaining 

  
 19 













 
Regulatory Approval with respect to the Licensed Products for the Field, and Lian will file such Regulatory Filings or Regulatory Approvals in Tarsus’s name in such Region. In such case, if
applicable Laws or Regulatory Authorities in such Region in the Territory later permit Lian to file and own such Regulatory Filings or Regulatory Approvals in Lian’s name, then Tarsus will permit such Regulatory Filings and Regulatory Approvals
to be filed in the name of and exclusively owned by Lian, and Tarsus will cooperate with Lian to assign and transfer such Regulatory Filings and Regulatory Approvals to Lian. Lian shall not assign or transfer any Regulatory Filings or Regulatory
Approvals in the Territory to any Third Party without the prior written consent of Tarsus, except to a Sublicensee or in connection with a permitted assignment of this Agreement in its entirety pursuant to Section 17.10. Lian shall be liable
for any Qualified Regulatory Agent’s breach of its obligations to Tarsus in connection with such Regulatory Approval activities. 
 8.2
Communication. To the extent permissible under applicable Law and practicable, Lian shall keep Tarsus informed of all significant matters arising from such Lian’s regulatory-related activities with respect to Licensed Products and shall
notify Tarsus of any material correspondence that it receives from a Regulatory Authority regarding any Licensed Product or that it submits to any Regulatory Authority regarding any Licensed Product, and will provide to Tarsus a copy of such
correspondence in Chinese or, to the extent available, a summary thereof in English, no later than [***] days after receipt of the correspondence to which it relates. Until such time as Lian obtains Regulatory Approval for a Licensed Product in the
Field in the Territory, to the extent permissible under applicable Law and practicable, Lian shall provide Tarsus reasonable advance notice of any material meetings, conferences or calls with Regulatory Authority(ies) in the Territory concerning

 22 













 (f) Lian shall pay Tarsus Commercial Milestone Payments corresponding to each Commercial
Milestone Event first achieved in each Calendar Year, regardless of how many Commercial Milestone Events are achieved in such Calendar Year. 

9.5 Consideration. Tarsus acknowledges that the Upfront Payment, Second Payment and payments for achievement of certain Development
Milestone Events are made in consideration of the contributions and activities of Tarsus under this Agreement (including, the corresponding Development that Tarsus agrees to undertake in connection with the Licensed Products outside the Territory)
in addition the rights granted by Tarsus to Lian hereunder. 
 9.6 Royalties. 

9.6.1 Net Sales Royalties. In each Calendar Year, Lian shall pay Tarsus royalties equal to the percentage of Aggregate Annual Net Sales
in such Calendar Year according to the table below. After each Calendar Quarter, royalty payments for such Calendar Quarter shall be payable based on Estimated Quarterly Net Sales (defined in Section 9.7) for such Calendar Quarter and then
trued up in the subsequent Calendar Quarter, as further set forth in Section 9.7. 
  

					
	 Aggregate Annual Net Sales
	  	Royalty Rate	 
	For that portion of Aggregate Annual Net Sales in such Calendar Year less than or equal to USD $[***]	  	 	[***]	 
	For that portion of Aggregate Annual Net Sales in such Calendar Year greater than USD $ [***] and less than or equal to USD $[***]	  	 	[***]	 
	For that portion of Aggregate Annual Net Sales in such Calendar Year greater than USD $[***]	  	 	[***]	 

 9.6.2 Royalty Term. On a Licensed
Product-by-Licensed Product and Region-by-Region basis, Lian’s obligation to pay
royalties set forth in Section 9.6.1 with respect to sales of a Licensed Product in a Region will commence upon the date of First Commercial Sale of such Licensed Product in such Region by or under the authority of Lian, its Affiliates, or any
Sublicensees, and expire upon the later to occur of (i) the expiration of the last-to-expire Valid Claim Covering such Licensed Product or use thereof that would be
infringed by the sale of such Licensed Product in such Region, (ii) the expiry of Regulatory Exclusivity for such Licensed Product in such Region; and (iii) the [***] anniversary of the date of First Commercial Sale of such Licensed
Product in such Region (the “Royalty Term” for such Licensed Product in such Region). 
 9.6.3 Royalty Reduction;
Royalty Floor. On a Licensed Product-by-Licensed Product and Region-by-Region basis,
Lian’s obligation to pay royalties set forth in Section 9.6.1 with respect to Net Sales of a Licensed Product in a Region will be subject to royalty reduction for (i) [***] of amounts paid by Lian as royalties on Net Sales in
respect of any Third Party licenses to Patents (or Patents together with Know-How) that are necessary to manufacture or sell such Licensed Product in such Region, (ii) (A) lack of any, or expiration of
all, Valid Claims of the Licensed Patents in such Region Covering the Compound or such Licensed Product or (B) [***], in either case of (A) or (B), royalty payments for such Licensed Product in such Region shall be reduced by
[***], and further, with respect to (B) only, [***]. [***]. Notwithstanding the foregoing, no royalty payment for any Licensed Product in a Calendar Quarter in a Region shall be reduced below [***]. [***]. 

  
 23 













 9.7 Net Sales Reports; Royalty Estimates and
True-up. Within [***] days following the end of each Calendar Quarter, Lian shall submit to Tarsus a written statement reporting a good faith estimate of Aggregate Annual Net Sales attributable to
such Calendar Quarter (“Estimated Quarterly Net Sales”) as broken down on a Licensed Product-by-Licensed Product and Region-by-Region basis, together with the amount of the total royalty payments due Tarsus in respect of such Net Sales [***] (“Net Sales Details”).
Tarsus will issue an invoice within [***] days following its receipt of such Estimated Quarterly Net Sales. Lian shall pay royalties based on Estimated Quarterly Net Sales within [***] days after its receipt of such invoice. Lian shall
provide Tarsus with the true Net Sales for such Calendar Quarter and related Net Sales Details at the time it provides the Estimated Quarterly Net Sales for the following Calendar Quarter and shall reconcile and
true-up the payments of royalties for each Calendar Quarter at the time it makes payments on the Estimated Quarterly Net Sales for the next Calendar Quarter. 

For example only: If the Estimated Quarterly Net Sales for the first Calendar Quarter of a Calendar Year (“Q1”) are
$[***], then Lian would pay Tarsus a royalty payment of $[***] for Q1. If after the second Calendar Quarter of such Calendar Year (“Q2”), the true amount of Aggregate Annual
Net Sales attributable to Q1 are $[***] and the Estimated Quarterly Net Sales attributable to Q2 are $[***], then Lian would pay Tarsus a royalty payment of $[***] after Q2 (i.e., [***] of the first $[***]
of the estimate for Q2 plus [***] of the next $[***] of the estimate for Q2 plus [***] of the $[***] increase from the estimated Aggregate Annual Net
Sales attributable to Q1 to the actual Aggregate Annual Net Sales attributable to Q1). 
 9.8 Payment Terms. 

9.8.1 All sums due to Tarsus shall be payable in United States dollars by bank wire transfer in immediately available funds to such bank
account(s) as Tarsus shall designate. 
 9.8.2 When Licensed Products are sold for monies other than United States dollars, the Net Sales of
such Licensed Products will first be determined in the foreign currency of the Region in which such Licensed Products were sold and then converted into equivalent United States funds. The exchange rate will be the applicable rate published by the
Wall Street Journal on the last Business Day of the Calendar Quarter in which such royalties accrued. 
 9.8.3 Interest on any the overdue
payment shall accrue at an annual interest rate, compounded monthly, equal to [***] , or if lower, the maximum rate allowed by applicable Laws, assessed from the day payment was initially due. Each day that Lian fails to deliver information
necessary to allow Tarsus to provide an invoice under this Agreement shall be deemed a day of late payment for the corresponding payment. 

9.9 Tax Withholding. 

9.9.1 Lian shall pay the Upfront Payment, Second Payment, and Development Milestone Payments (including, any
pre-payment pursuant to Section 5.3) to Tarsus from a legal entity based in the United States in good standing and from a bank in the United States; provided that if Lian pays the Upfront Payment, Second
Payment, and Development Milestone Payments from a legal entity based outside the United States and if any taxes, levies, duties, or other governmental assessments (“Taxes”) are paid or required to be withheld under any applicable Laws,
then Lian shall pay to Tarsus an additional amount equal to the amount that is required to be paid or withheld to the relevant Government Authority such that Tarsus receives the full amount of the Upfront Payment, Second Payment, and Development
Milestone Payments (i.e. all Upfront Payment, Second Payment, and Development Milestone Payments to Tarsus under this Agreement are net of any Taxes and withholding required). 

  
 24 













 9.9.2 Subject to Section 9.9.1, each Party shall be solely responsible for the payment
of the Taxes imposed on its share of income arising from its activities or receipt of payments under this Agreement. Subject to Section 9.9.1, in the event any Tax based on income to Tarsus is required to be withheld and deducted from payments
by Lian pursuant to this Agreement under applicable Laws, Lian will make such deduction and withholding and will pay the remainder to Tarsus, any amounts so withheld and deducted will be remitted by Lian on a timely basis to the appropriate
Governmental Authority, and Lian will be deemed to have fulfilled all of its payment obligations to Tarsus with respect to such payments. Official receipts of payment of any withholding tax shall be secured and sent to Tarsus as evidence of such
payment. 
 9.9.3 Tarsus and Lian agree to reasonably assist the other Party in claiming exemption from Tax deductions or withholdings under
double taxation or similar agreements or treaties from time to time in force and in minimizing the amount required to be so withheld or deducted. 

9.10 Financial Audits. Lian shall keep or cause to be kept books of account containing all information that may be necessary for the
purpose of calculating amounts payable by Lian in connection with this Agreement for a period of [***] Calendar Years following the end of the Calendar Year during which such amounts were payable. Tarsus may appoint an independent public
accountant (on a non-contingency basis and reasonably acceptable to Lian; any “Big 4” accountant shall be deemed acceptable to Lian), at Tarsus’s expense and subject to such accountant entering
into a confidentiality agreement with Lian, to inspect such books of account in order to verify the calculation of any amounts payable to Tarsus hereunder. Such inspections shall be performed not more frequently than once in any [***] month
period and upon reasonable prior notice, and shall be conducted during regular business hours in such a manner as to not unreasonably interfere with Lian’s normal business activities. Tarsus’s accountant may only share with Tarsus the
report containing the summary results of its inspection, but not the books of account reviewed by the accountant during the audit, and such report shall constitute Lian’s Confidential Information. If any such inspection reveals that any payment
(a) that should have been paid by Lian is greater than those that were actually paid by Lian, then Lian shall promptly pay the underpaid amount to Tarsus or (b) that was actually paid by Lian is greater than those that should have paid by
Lian, then Lian shall credit the overpaid amount against future royalty payments to Tarsus. If the payments that should have been paid by Lian are at least [***] greater than those that were actually paid by Lian, then Lian shall also
reimburse Tarsus for the reasonable out-of-pocket costs of such inspection. 

10. CONFIDENTIAL INFORMATION. 

10.1 Definition. “Confidential Information” means confidential or proprietary information, data or Know-How, whether provided in written, oral, visual or other form, provided by one Party (the “Disclosing Party”) to the other Party (the “Receiving Party”) in
connection with this Agreement, including the Licensed Know-How and other information relating to the Disclosing Party’s existing or proposed research, development efforts, patent applications, business
or products. Confidential Information shall not include any such information that: (a) is already rightfully known to the Receiving Party or its Affiliates (other than under an obligation of confidentiality at least as stringent as required in
this Agreement) at the time of disclosure (as evidenced by written records of the Receiving Party); (b) is or becomes generally available to the public other than through any act or omission of the Receiving Party or its Affiliates in breach of this
Agreement; (c) is disclosed to the Receiving Party or its Affiliates without an obligation of confidentiality by a Third Party who had no separate nondisclosure obligation in respect of such information; or (d) is independently discovered
or developed by or on behalf of the Receiving Party or its Affiliates without the use of or reference to the Confidential Information of the Disclosing Party (as evidenced by written records of the Receiving Party). The Parties agree that with
respect to Licensed Know-How, Tarsus shall be deemed the Disclosing Party. 

  
 25 













 10.2 Confidentiality. The Receiving Party shall, during the Term and for a period of
[***] years thereafter (except that with respect to any Confidential Information that could qualify as a trade secret, until such Confidential Information otherwise ceases to be deemed Confidential Information in accordance with any of
clauses (a)-(d) of Section 10.1), keep in confidence all Confidential Information of the Disclosing Party with the same degree of care it employs to maintain the confidentiality of its own Confidential Information, but no less than a reasonable
degree of care. The Receiving Party shall not use such Confidential Information for any purpose other than for the purposes contemplated by this Agreement or disclose the same to any other Person other than to such of its Affiliates, its
sublicensees, and its and their employees, agents and subcontractors who have a need to know such Confidential Information for the purposes of exercising the rights or performing the obligations of the Receiving Party under this Agreement. A
Receiving Party shall advise any such Affiliate, employee, agent, and subcontractor who receives Confidential Information of such obligations, and the Receiving Party shall ensure (through enforcement of written agreements or otherwise) that all
such Affiliates, employees, agents, and subcontractors comply with such obligations as if they had been a Party hereto. The Receiving Party will be liable for breach of confidentiality by any of its Affiliates and its and their employees, agents, or
subcontractors. 
 10.3 Permitted Disclosure and Use. The Receiving Party shall have the right to disclose Confidential Information
if, (a) in the reasonable opinion of the Receiving Party’s legal counsel, such disclosure is required by any applicable Laws (including, but not limited to, the rules of any stock exchange), provided that, to the extent practicable, the
Receiving Party gives adequate prior notice of such disclosure to the Disclosing Party and the Receiving Party seeks confidential treatment of such Confidential Information to the maximum extent permitted by the relevant Governmental Authority; or
(b) a court, tribunal, administrative agency or other Governmental Authority orders such disclosure, provided that the Receiving Party gives adequate prior notice of such disclosure to the Disclosing Party to permit the Disclosing Party to
intervene and to request protective orders or other confidential treatment. The Receiving Party will cooperate reasonably with any such efforts by the Disclosing Party. In addition to the exceptions contained in Section 10.2, each Party may use
such Confidential Information and disclose Confidential Information of the other Party to Third Parties under appropriate terms and conditions (including confidentiality provisions substantially similar to these in this Agreement) to the extent (and
solely to the extent) that such use and disclosure is reasonably necessary in the following instances: [***]. The disclosing Party shall be responsible for any breaches of confidentiality by such Third Parties to whom it has disclosed the other
Party’s Confidential Information. The Parties shall also be permitted to make disclosures consistent with, and pursuant to, Sections 17.1 and 17.4. 

10.4 [***]. 
 10.5
Remedies. Money damages may not be an adequate remedy if this Article 10 is breached and, therefore, either Party may, in addition to any other legal or equitable remedies, seek an injunction or other equitable relief in any court of
competent jurisdiction against such breach or threatened breach without the necessity of posting any bond or surety. 
 11. NON-AMENDMENT OF ELANCO AGREEMENT. Tarsus shall not modify or amend the Elanco Agreement in any way that would materially and adversely affect Lian’s rights under this Agreement. Tarsus shall not
prematurely terminate the Elanco Agreement. Tarsus shall promptly notify Lian of any material breach by Tarsus of which Elanco notifies Tarsus or any material breach by Elanco of the Elanco Agreement, and in the event of a breach by Tarsus and
failure by Tarsus to cure such breach in a timely manner, will permit Lian to cure such breach on Tarsus’s behalf upon Lian’s reasonable written request.

“Indemnifying Party”) in writing if it becomes aware of a Claim (actual or potential) by any Third Party or any proceeding (including, but not limited to, any investigation by a Governmental Authority) for which
indemnification may be sought and will give such related information as the Indemnifying Party shall reasonably request; provided, however, that failure by an Indemnified Party to give notice of a Claim as provided in this Section 13.3.1
will not relieve the Indemnifying Party of its indemnification obligation under this Agreement, except and only to the extent that such Indemnifying Party is materially prejudiced as a result of such failure to give notice. 

13.3.2 Defense of Claim. The Indemnifying Party shall have sole control over the defense and settlement of any such Claims and shall be
responsible for satisfying and discharging any award made to or settlement reached with the Third Party pursuant to the terms of this Agreement. The Indemnifying Party shall use counsel reasonably acceptable to the Indemnified Party and shall be
responsible for the fees and expenses of such counsel related to such proceeding. In any such proceeding, the Indemnified Party, at its sole expense, shall have the right to retain its own counsel at its own expense. If the Indemnifying Party fails
to assume control over the defense of any such Claims, then the Indemnified Party may control such defense using counsel of its choosing, and the Indemnifying Party will be responsible or the reasonable fees and expenses of such counsel related to
such proceeding. The Party controlling the defense of any Claim will keep the other Party advised of the status and material developments of such Claim and the defense thereof and will reasonably consider recommendations made by the other Party with
respect thereto. The other Party will reasonably cooperate with the Party controlling such defense and its Affiliates and agents in defense of the Claim, with all
out-of-pocket costs of such cooperation to be borne by the Indemnifying Party. 

13.3.3 Settlement. The Indemnifying Party shall not, without the written consent of the Indemnified Party (which consent shall not be
unreasonably withheld, refused, conditioned or delayed), effect any settlement of any such Third Party Claim, unless such settlement includes an unconditional release of the Indemnified Party from all liability on such Claims or that imposes any
liability or obligation on the Indemnified Party. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, agree to any settlement of such Third Party Claim or consent to any judgment in respect thereof unless
such settlement or judgment includes a full and unconditional release of the Indemnified Party from all liability with respect thereto, that imposes any liability or obligation on the Indemnified Party, or that adversely affects the rights of the
Indemnified Party. 
 14. PROSECUTION; LITIGATION. 

14.1 Prosecution and Maintenance of Patents. 

14.1.1 Tarsus shall have the first right (but not the obligation) to Prosecute the Licensed Patents at its own expense. Tarsus shall keep Lian
reasonably updated with regard to the Prosecution of the Licensed Patents in the Territory and shall provide Lian with copies of all applications, filings, and official correspondence (including, applications, office actions and responses) relating
thereto. Tarsus will provide Lian a reasonable opportunity to provide comments on drafts of all material filings and correspondence related to Prosecution of the Licensed Patents in the Territory (which comments Tarsus shall consider in good faith
but may accept or reject in its sole discretion). Notwithstanding the foregoing, with respect to any Licensed Patent that is licensed to Tarsus from a Third Party, the foregoing review and comment rights will only apply to the extent that Tarsus has
such rights. 

  
 30 













 14.1.2 Tarsus may abandon the Prosecution of any Licensed Patents in its sole discretion.
Tarsus will provide Lian at least [***] days’ notice of its intention to abandon such Prosecution and provide Lian with reasonable opportunity, but not the obligation, to assume responsibility for the Prosecution of such Licensed Patents
as set forth below. In the event that Tarsus abandons the Prosecution of Licensed Patents in the Territory at any time during the Term, Lian may assume the Prosecution responsibility therefor in the name of Tarsus, and the costs associated with such
prosecution shall be paid by Lian at its sole discretion. No such action by Lian will change the ownership or license provisions with respect to the applicable Licensed Patent unless agreed by the Parties in writing. Tarsus will execute all
documents that Lian may reasonably request for such purposes. Lian shall have no further obligations to Tarsus with respect to any such Licensed Patents and such Licensed Patent shall be deemed expired for all purposes of Section 9.6.3.
Notwithstanding the foregoing, with respect to any Licensed Patent that is licensed to Tarsus from a Third Party, the foregoing will only apply to the extent that Tarsus has such rights. 

14.2 Enforcement and Defense. 

14.2.1 Notice of Infringement. Each Party shall promptly notify the other in writing (a) of any actual or suspected infringement
or misappropriation by a Third Party of any Licensed IP in the Territory (including unauthorized importation into the Territory for sale in the Territory), of which it becomes aware, or (b) upon receiving notification that a Licensed Patent is
subject to a declaratory judgment action, opposition, nullity action, interference, ex parte and inter partes reexaminations, ex parte and inter partes review, post-grant review, derivation proceeding, or similar action alleging non-infringement, invalidity or unenforceability in the Territory, which notification shall specify in reasonable detail the nature of such actual or suspected infringement or judicial action. 

14.2.2 Right to Enforce. As between the Parties (and, with respect to the Elanco Patents, subject to Elanco’s approval), Lian
shall have the first right, using counsel of its choice, to enforce the applicable Licensed Patent(s) in the Territory with respect to infringement in the Field (a “Third Party Infringement Action”), at its expense, and
Tarsus shall reasonably cooperate, in good faith, with Lian in such Action, at Lian’s expense. Lian shall provide Tarsus with an opportunity to make suggestions and comments regarding such enforcement, and Lian shall consider all such
suggestions and comments in good faith. Lian shall keep Tarsus reasonably informed of the status and progress of the litigation. Without limiting the foregoing, if Lian is authorized hereunder to initiate an Action against a Third Party under this
Section 14.2.2, but Lian is not recognized by the applicable court or other relevant body as having the requisite standing to pursue such action, then at Lian’s request, Tarsus shall join in as party-plaintiff or commence such Action in
its own name and, in either event, cooperate with Lian, at Lian’s expense. If Lian does not elect to enforce the Licensed Patents against a Third Party Infringement Action within [***] days after one Party informs the other of such Third
Party Infringement Action, then Tarsus may enforce the Licensed Patents against such Third Party. 
 14.2.3 Defense. Each Party will
promptly notify the other Party if a Third Party brings any Action alleging patent infringement by Lian or Tarsus or any of their respective Affiliates or Sublicensees with respect to the Development, manufacture or Commercialization of any Licensed
Product in the Field in the Territory (any such Action, an “Infringement Claim”). Lian will have the right, but not the obligation, to control the defense and response to any such Infringement Claim in the Field in the
Territory with respect to Lian’s activities, at Lian’s sole cost and expense, and Tarsus will have the right, at its own expense, to be represented in any such Infringement Claim in the Field in the Territory by counsel of its own choice.
Tarsus will have the sole right, but not the obligation, to control the defense and response to any such Infringement Claim with respect to Tarsus’s activities, including any such Infringement Claim outside of the Field or outside of the
Territory. Upon the request of the Party controlling the response to the Infringement Claim, the other Party will reasonably cooperate with the controlling Party in the reasonable defense of such Infringement Claim. The other Party will have the
right to consult with the controlling Party 

  
 31 













 
concerning any Infringement Claim and to participate in and be represented by independent counsel in any associated litigation. If the Infringement Claim is brought against both Parties, then
each Party will have the right to defend against the Infringement Claim. The Party defending an Infringement Claim under this Section 14.2.3 will (a) consult with the other Party as to the strategy for the prosecution of such defense,
(b) consider in good faith any comments from the other Party with respect thereto, and (c) keep the other Party reasonably informed of any material steps taken and provide copies of all material documents filed, in connection with such
defense. The Party controlling the defense against an Infringement Claim will have the right to settle such Infringement Claim on terms deemed reasonably appropriate by such Party, provided that, unless any such settlement includes a full and
unconditional release from all liability of the other Party and does not adversely affect the rights of the other Party, any such settlement will be subject to the other Party’s prior written consent. 

14.2.4 Distribution of Recoveries. Any damages obtained (whether in judgment or settlement) in a Third Party Infringement Action to the
extent attributable to infringement of Licensed Patents in the Field in the Territory shall be distributed as follows: (a) first, each Party and Elanco shall be reimbursed for its reasonable out-of-pocket costs (if any) paid in connection with the proceeding, and Tarsus shall be reimbursed for such amounts as necessary to reimburse Elanco in connection with the proceeding as required under the
Elanco Agreement; (b) second, Lian shall retain [***] of such amounts if it was the Party to enforce such Third Party Infringement Action, provided that such recoveries shall be [***]; and (c) finally, if Tarsus
was the Party to enforce such Third Party Infringement Action, then Tarsus shall retain [***] of the remaining amount and pay the remaining [***] to Lian. 

14.2.5 Settlement. In no case may Lian enter into any settlement or consent judgment or other voluntary final disposition with respect
to any infringement Action referenced in this Section 14.2 that: (a) extends, or purports to exercise, Lian’s rights under the Licensed IP beyond the rights granted pursuant to this Agreement; (b) makes any admission regarding
wrongdoing by Tarsus or the invalidity, unenforceability or absence of infringement of any Licensed Patents; (c) subjects Tarsus to an injunction or other equitable relief; or (d) obligates Tarsus to make a monetary payment; in all cases
without the prior written consent of Tarsus, which consent will not be unreasonably withheld or delayed. Similarly, in no case may Tarsus enter into any settlement or consent judgment or other voluntary final disposition with respect to any
infringement Action referenced in this Section 14.2 that: (i) limits Lian’s rights or interests under the Licensed IP under this Agreement; (ii) makes any admission regarding wrongdoing by Lian; (iii) subjects Lian to an
injunction or other equitable relief; or (iv) obligates Lian to make a monetary payment; in all cases without the prior written consent of Lian, which consent shall not be unreasonably withheld or delayed. 

14.2.6 In-Licensed Patents. With respect to any Licensed Patent that is licensed to Tarsus from
a Third Party, to the extent Tarsus has the right to do so, Tarsus will cooperate with Lian to enforce, such Licensed Patents in the Field and in the Territory in the same manner as set forth in this Section 14.2. As between Tarsus and Lian,
any recoveries from enforcement of such Licensed Patents owned by a Third Party shall be shared in accordance with Section 14.2.4, after deducting from such recoveries any amounts owed to the Third Party licensor for such enforcement. 

15. ANTI-CORRUPTION.  

15.1 In the performance of its obligations under this Agreement, each Party shall comply and shall cause its and its Affiliates’
employees, licensees, sublicensees, and contractors (collectively with respect to Lian, “Lian Personnel”) to comply with all applicable Laws. 

  
 32 













 15.2 Lian and Lian Personnel shall not, in connection with the performance of their
respective obligations under this Agreement, directly or indirectly through Third Parties, pay, promise, or offer to pay, or authorize the payment of, any money or give any promise or offer to give, or authorize the giving of anything of value to a
Public Official or Entity or other person for purpose of obtaining or retaining business for or with, or directing business to, any person, including, Lian (and Lian represents and warrants that as of the Effective Date, Lian and Lian Personnel have
not directly or indirectly promised, offered, or provided any corrupt payment, gratuity, emolument, bribe, kickback, illicit gift, or hospitality or other illegal or unethical benefit to a Public Official or Entity or any other person in connection
with the performance of such Party’s obligations under this Agreement, and Lian covenants that Lian and Lian Personnel shall not, directly or indirectly, engage in any of the foregoing). 

15.3 Lian and Lian Personnel, in connection with the performance of its obligations under this Agreement, shall not violate or cause the
violation of the Anti-Corruption Laws, Export Control Laws, or any other applicable Laws, or otherwise cause any reputational harm to Tarsus. 

15.4 Lian shall promptly notify Tarsus if it has any knowledge of or reasonably believes that there may be a violation of the Anti-Corruption
Laws, Export Control Laws, or any other applicable Laws in connection with the performance of this Agreement or the Development or Commercialization of any Licensed Product. 

15.5 In the event that Lian has violated or been suspected of violating any of the representations, warranties, or covenants in this Article
15, Lian will cause Lian Personnel or others working under its direction or control to submit to periodic training that it will provide on Anti-Corruption Law compliance or other relevant compliance. 

15.6 Lian will, at Tarsus’s request (not more than once per Calendar Year), provide reasonable documentation evidencing its compliance, in
connection with the performance of its obligations under this Agreement, with the representations, warranties, or covenants in Article 15. 

16. TERM AND TERMINATION. 

16.1 Term. This Agreement shall commence on the Effective Date and shall expire upon the expiration of the Royalty Term in the Territory
for all Licensed Products, unless earlier terminated as provided in this Article 16 (the “Term”). 
 16.2
Termination of this Agreement by Lian for Convenience. Lian may terminate this Agreement for any reason upon [***] days’ prior notice to Tarsus. 

16.3 Termination for Breach. 

16.3.1 Either Party may terminate this Agreement upon notice to the other Party for any material breach of this Agreement by the other Party,
if such material breach is not cured within [***] days (or [***] days for payment breaches) after the breaching Party receives notice of such breach from the non-breaching Party, or, if such
breach can be cured but cannot be cured within [***] days and if the breaching Party prepares and uses reasonable efforts to follow a cure plan, up to [***] days. The written notice describing the alleged material breach will provide
sufficient detail to put the breaching Party on notice of such material breach. [***]. 
 16.3.2 [***] may terminate this Agreement
immediately upon notice to Lian if [***] and fails to cure such breach within [***] days. For clarity, such termination is not subject to any tolling or opportunity to cure following such then [***] day period. Additionally,
Section 17.6 shall not apply with respect to any breach of Section 9.1. 

  
 33 













 16.4 Termination for Patent Challenge. Tarsus shall have the right to terminate this
Agreement in its entirety, immediately upon the issuance of notice to Lian, if at any time Lian or any of its Affiliates or any Sublicensee challenges, or causes to be challenged, in any way, the validity, enforceability or scope of the Licensed
Patents in any court or before any Governmental Authority with authority to determine the validity, enforceability or scope of such Licensed Patents (a “Patent Challenge”), or cause or request, without the prior written
approval of Tarsus, a review by any such court or Governmental Authority of the same. For clarity, a Patent Challenge includes Lian or any of its Affiliates or any Sublicensee, directly or indirectly: (i) initiating or requesting an
interference or opposition proceeding with respect to any Licensed Patents; (ii) making, filing or maintaining any claim, demand, lawsuit, or cause of action to challenge the validity or enforceability of any Licensed Patents; or
(iii) opposing any extension of, or the grant of a supplementary protection certificate with respect to, any Licensed Patents. Notwithstanding any provision to the contrary in this Agreement, Tarsus’s right to terminate this Agreement
under this Section 16.4 will not apply to any Patent Challenge that (a) (i) is a Patent Challenge of Licensed Patent(s) held in the Territory (and not any other Licensed Patent(s)) first made by Lian or any of its Affiliates or any
Sublicensee in defense of a claim of patent infringement brought by Tarsus under the applicable Licensed Patents held in the Territory, or (ii) is brought by any Sublicensee if Lian terminates such Sublicensee’s sublicense to all Licensed
IP within [***] days after Tarsus’s notice to Lian under this Section 16.4; and (b) is not a Patent Challenge of any Elanco Patent. 

16.5 Termination for Bankruptcy. Either Party hereto shall have the right to terminate this Agreement, to the extent permitted by
applicable Laws, forthwith upon notice to the other Party (a) if the other Party is declared insolvent or bankrupt by a court of competent jurisdiction, (b) if a voluntary or involuntary petition of bankruptcy, reorganization, liquidation,
or receivership is filed in any court of competent jurisdiction against the other Party and such petition is not dismissed or stayed within [***] days after filing or (c) if the other Party shall make or execute an assignment of substantially
all of its assets for the benefit of creditors. 
 16.6 Rights in Bankruptcy. 

16.6.1 All rights and licenses now or hereafter granted by either Party to the other Party under or pursuant to this Agreement are, for all
purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of rights to “intellectual property” as defined in the U.S. Bankruptcy Code. Upon the filing or institution of bankruptcy, reorganization, liquidation or receivership
proceedings, upon the appointment of a receiver or trustee over all or substantially all property, or upon an assignment of a substantial portion of the assets for the benefit of creditors by either Party, such Party agrees that the other Party, as
licensee of such rights under this Agreement, will retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code. Each Party will, during the Term, create and maintain current copies or, if not amenable to copying,
detailed descriptions or other appropriate embodiments, to the extent feasible, of all Intellectual Property Rights licensed by such Party under this Agreement. Each Party acknowledges and agrees that “embodiments” of Intellectual Property
Rights within the meaning of Section 365(n) include laboratory notebooks, cell lines, product samples and inventory, research studies and data, all Regulatory Approvals (and all applications for Regulatory Approval) and rights of reference
therein, the Licensed Know-How, Licensed Patents, and all information related to the Licensed Know-How or Licensed Patents. If (A) a case under the U.S. Bankruptcy
Code is commenced by or against either Party, (B) this Agreement is rejected as provided in the U.S. Bankruptcy Code and (C) the other Party elects to retain its rights hereunder as provided in Section 365(n) of the U.S. Bankruptcy
Code, the Party subject to such case (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee) will: 

  
 34 













 (a) provide the non-subject Party with all such
Intellectual Property Rights (including all embodiments thereof) held by the subject Party and such successors and assigns, or otherwise available to them, immediately upon the non-subject Party’s written
request. Whenever the subject Party or any of its successors or assigns provides to the non-subject Party any of the Intellectual Property Rights licensed hereunder (or any embodiment thereof) pursuant to this
Section 16.6, the non-subject Party will have the right to perform the subject Party’s obligations hereunder with respect to such Intellectual Property Rights, but neither such provision nor such
performance by the non-subject Party will release the subject Party from liability resulting from rejection of the license or the failure to perform such obligations; and 

(b) not interfere with the non-subject Party’s rights under this Agreement, or any agreement
supplemental hereto, to such Intellectual Property Rights (including such embodiments), including any right to obtain such Intellectual Property Rights (or such embodiments) from another entity, to the extent provided in Section 365(n) of the
U.S. Bankruptcy Code. 
 16.6.2 All rights, powers and remedies of the non-subject Party provided in
this Section 16.6 are in addition to and not in substitution for any other rights, powers, and remedies now or hereafter existing at law or in equity (including the U.S. Bankruptcy Code) in the event of the commencement of a case under the U.S.
Bankruptcy Code with respect to the subject Party. The Parties intend the following rights to extend to the maximum extent permitted by applicable Law, and to be enforceable under U.S. Bankruptcy Code Section 365(n): 

(a) the right of access to any Intellectual Property Rights (and all embodiments thereof) of the subject Party or any Third Party that is
licensed or sublicensed to the non-subject Party under this Agreement; and 
 (b) the right to
contract directly with any Third Party to complete the contracted work. 
 16.7 Effects of Termination. 

16.7.1 Upon expiration of the Royalty Term of each Licensed Product in each Region, the License will become
non-exclusive, perpetual, irrevocable, fully paid-up, royalty-free, fully sublicenseable, and transferable in the Field and in the Territory for such Licensed Product in
such Region. 
 16.7.2 Upon the early termination of this Agreement: (a) all rights and licenses granted to Lian herein shall terminate
and revert to Tarsus; (b) at Tarsus’s request, Lian shall either promptly transition to Tarsus any on-going Clinical Trials with respect to the applicable Licensed Product or wind down such Clinical
Trials; (c) Lian shall promptly provide Tarsus with all data and results in its possession relating to Licensed Products; (d) Lian will promptly assign or transfer, or cause to be assigned and transferred to Tarsus (or if not so
assignable, Lian shall take all reasonable actions to make available to Tarsus the benefits of), all Regulatory Filings, Manufacturing Technology, Know-How, Regulatory Approvals, and trademarks (including all
trademark applications and registration and associated goodwill) to the extent solely related to the Licensed Products (collectively, “Product Materials”); and (e) all rights granted by Lian to Tarsus under this
Agreement will survive. Lian will perform the foregoing activities ((b) through (d)) at its sole cost and expense, provided that, if this Agreement is terminated by Lian pursuant to Section 16.3 or Section 16.5, then Tarsus will reimburse
Lian’s reasonable costs and expenses for such activities. Lian shall, at Tarsus’s expense, provide to Tarsus the necessary information to permit Tarsus to effect and perfect the transfer of all the Product Materials, and shall reasonably
cooperate with Tarsus in executing appropriate documents to effectuate the transfer or assignment for the relevant Product Materials (including the Regulatory Approvals and trademarks) that are in the name of Lian or any of its Affiliates. Lian will
have the right, for a period of [***] days following termination of this Agreement, to sell or otherwise dispose of any Licensed Products on hand or in the process of being manufactured at the time of such termination. 

  
 35 













 16.7.3 Except as otherwise provided herein, upon termination of this Agreement, all
remaining records, documents, materials, or other media in each Receiving Party’s possession or control containing the Disclosing Party’s Confidential Information and to which such Receiving Party does not retain rights hereunder, shall
promptly be returned or destroyed at the request of the Disclosing Party. Notwithstanding the foregoing, copies of such records may be retained by legal counsel for such Receiving Party solely for archival purposes. For clarity, Tarsus has no
obligation to return or destroy records, documents, materials, or other media relating to any Licensed Products. 
 16.8 Survival. The
termination or expiration of this Agreement shall not relieve the Parties of any liability accruing prior to such termination, and any such termination shall be without prejudice to the rights of either Party against the other. The provisions of
Articles 1, 10, 13, and 17 and Sections 2.7, 5.6.2 (with respect to Lian’s obligations for the period set forth therein), 8.2, 8.3.1, 9.10, 12.4, 12.5, 16.6, 16.7, and 16.8 shall survive any termination or expiration of this Agreement. 

17. MISCELLANEOUS. 
 17.1
LianBio Guarantee. LianBio hereby unconditionally and irrevocably guarantees, as a primary obligor and not merely as surety, the due and punctual payment and performance of all obligations of Lian under this Agreement (the “Lian
Obligations”). LianBio agrees that the Lian Obligations may be extended, modified, or renewed, in whole or in part, without notice or further assent from it, and that it will remain bound upon its guarantee notwithstanding any
extension, modification, or renewal of any Lian Obligation. The obligations of LianBio under this Section 17.1 will not be affected by the failure of Tarsus to assert any claim or demand or to enforce any right or remedy against Lian under the
provisions of this Agreement or otherwise. LianBio further agrees that its guarantee constitutes a guarantee of payment and performance when due and not of collection. However, prior to seeking satisfaction of any Lian Obligation by LianBio, Tarsus
will first direct any requests with respect to the satisfactions of any outstanding or overdue Lian Obligations to Lian. 
 17.2
Affiliates. Each Party may discharge any obligations and, to the extent applicable, subject to the provisions concerning sublicenses, exercise any rights hereunder through delegation of its obligations or rights to any of its Affiliates,
provided that each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement and will cause its Affiliates to comply with the provisions of this Agreement in connection with such performance.

 17.3 Publications. Lian will notify Tarsus of any planned abstracts, oral presentations and manuscripts relating to the publication
of clinical data and other scientific data generated in the course of Development of the relevant Licensed Product by Lian. Lian shall provide a draft of the planned submission or presentation at least [***] days prior to publication or
presentation (as the case may be) and will incorporate in good faith all comments of Tarsus to prevent the disclosure of any Confidential Information of Tarsus contained therein, and will allow for the filing of patent applications as necessary to
preserve proprietary rights in the information in the material being submitted for publication or presentation. The review period may be extended for an additional [***] days if Tarsus can demonstrate a reasonable need for such extension for
purposes of the preparation and filing of patent applications. The Parties will each comply with standard academic practice regarding authorship of scientific publications and recognition of contribution of other parties in any such publications or
presentations. 
 17.4 Public Announcements. Lian and Tarsus have agreed on language of a joint press release announcing this
Agreement, which, unless otherwise agreed by the Parties, will be issued by the Parties promptly after the Effective Date substantially in the form attached hereto as Schedule 17.4. Except as may be expressly permitted under this Section 17.4
or mandated by applicable Laws or the rules of any stock exchange, neither Party will make any public announcement of any information regarding this Agreement without the prior written consent of the other Party. Once any statement is approved for
disclosure by the Parties, either Party may make a subsequent public disclosure containing the same information disclosed in such prior public announcement without further approval of the other Party. 

  
 36 













 17.5 Relationship of the Parties. This Agreement is not a partnership agreement and
nothing in this Agreement shall be construed to establish a relationship of partners or joint venturers between the Parties. 
 17.6 Force
Majeure. The occurrence of an event that materially interferes with the ability of a Party to perform its obligations or duties hereunder which is not within the reasonable control of the Party affected, and which could not with the exercise of
Commercially Reasonable Efforts have been avoided (“Force Majeure Event”), including, but not limited to, war, rebellion, earthquake, fire, accident, strike, riot, civil commotion, act of God, epidemic, pandemic, quarantine,
inability to obtain raw materials, delay or errors by shipping companies or change in Law, shall not excuse such Party from the performance of its obligations or duties under this Agreement, but shall merely suspend such performance (other than
performance of payment obligations) during the Force Majeure Event. The Parties agree the effects of the COVID-19 pandemic that is ongoing as of the Effective Date may be invoked as a Force Majeure Event for
the purposes of this Agreement even though the pandemic is ongoing to the extent those effects are not reasonably foreseeable by the Parties as of the Effective Date. The Party subject to a Force Majeure Event shall promptly notify the other Party
of the occurrence and particulars of such Force Majeure Event and shall provide the other Party, from time to time, with its best estimate of the duration of such Force Majeure Event and with notice of the termination thereof. The Party so affected
shall use Commercially Reasonable Efforts to avoid or remove such causes of non-performance as soon as is reasonably practicable. Upon termination of the Force Majeure Event, the performance of any suspended
obligation or duty shall without delay recommence. The Party subject to the Force Majeure Event shall not be liable to the other Party for any damages arising out of or relating to the suspension or termination of any of its obligations or duties
under this Agreement by reason of the occurrence of a Force Majeure Event, provided that such Party complies in all material respects with its obligations under this Section 17.6. 

17.7 Dispute Resolution. Subject to the dispute escalation and decision-making provisions of Article 4, in the event of any dispute,
controversy or claim hereunder arising out of or relating to this Agreement either Party may, on [***] days notice to the other Party, initiate binding arbitration in accordance with the then-current Rules of Arbitration of the International
Chamber of Commerce (the “ICC”). The Parties shall select a mutually acceptable arbitrator within [***] days of the request of the Party invoking this dispute resolution procedure. If the Parties are unable to agree
upon an arbitrator, then the ICC shall select a qualified, independent arbitrator. Such arbitration will be held in New York City, New York and conducted in the English language. The decision of the arbitrator will be final and binding on the
Parties. The prevailing Party may enforce any arbitration decision or award, and either Party may seek injunctive, equitable or similar relief (without the requirement of arbitration), in any court having competent jurisdiction. 

17.8 Governing Law. This Agreement shall be construed, and the respective rights of the Parties determined, according to the substantive
law of the State of New York without regard to the conflict of laws principles thereof. The United Nations Convention on the International Sale of Goods shall not apply to this Agreement. 

17.9 Attorneys’ Fees and Related Costs. The prevailing Party, as determined by the arbitrators, shall be entitled to (a) its
share of fees and expenses of the arbitrators and (b) its attorneys’ fees and any and all associated costs and expenses. In determining which Party “prevailed,” the arbitrators shall consider (i) the significance, including
the financial impact, of the claims prevailed upon and (ii) the scope of claims prevailed upon, in comparison to the total scope of the claims at issue. If the arbitrators determine that, given the scope of the arbitration, neither Party
“prevailed,” the arbitrators shall order that the Parties (1) share equally the fees and expenses of the arbitrators and (2) bear their own attorneys’ fees and associated costs and expenses. 

  
 37 













 17.10 Assignment. This Agreement may not be assigned by either Party, in whole or in
part, whether voluntarily or by operation of law, without the prior written consent of the other Party; provided that, without prior written consent, either Party may assign this Agreement, in whole or in part, to any of its Affiliates if such Party
guarantees the performance of this Agreement by such Affiliate, or to a successor to all or substantially all of the assets or business of such Party to which this Agreement relates, whether by merger, sale of stock, sale of assets or other similar
transaction. Any assignment in violation of this provision is void and without effect. This Agreement shall be binding upon and inure to the benefit of the Parties hereto, their permitted successors, legal representatives and assigns. 

17.11 Notices. All demands, notices, consents, approvals, reports, requests and other communications hereunder must be in writing, in
English, and will be deemed to have been duly given only if delivered personally, by mail (first class, postage prepaid), or by overnight delivery using a globally-recognized carrier, to the Parties at the following addresses:
