capacity, including debtor-in-possession) and its successors and assigns (including a trustee) will: (1) provide Lian with all such Intellectual Property (including
all embodiments thereof) held by Landos and such successors and assigns, or otherwise available to them, immediately upon Lian’s written request. Whenever Landos or any of its successors or assigns provides to Lian any of the Intellectual
Property licensed hereunder (or any embodiment thereof) pursuant to this Section 2.6(a) (Rights in Bankruptcy), Lian will have the right to perform Landos’ obligations hereunder with respect to such Intellectual Property, but neither such
provision nor such performance by Lian will release Landos from liability resulting from rejection of the license or the failure to perform such obligations; and (2) not interfere with Lian’s rights under this Agreement, or any agreement
supplemental hereto, to such Intellectual Property (including such embodiments), including any right to obtain such Intellectual Property (or such embodiments) from another entity, to the extent provided in Section 365(n) of the U.S. Bankruptcy

Plan, and Lian will support Landos on such global development for such Global Trial by (i) including Clinical Trial sites in the Territory [***], (ii) being responsible for any costs and expenses incurred by or on behalf of Lian for its
participation in such Global Trial conducted in the Territory, and (iii) using Commercially Reasonable Efforts to enroll patients in the Territory equal to a minimum of [***] of the total patients in such Global Phase III Trial (the
“Patient Commitment”). In the event that Lian participates in such a Global Phase III Trial and fails to enroll sufficient patients in the Territory to meet the Patient Commitment (the “Patient Shortfall”), and
Landos instead enrolls patients in such Global Phase III Trial in lieu of Lian in order to meet the Patient Commitment, then Lian will reimburse Landos for the number of patients representing the Patient Shortfall that Landos so enrolls in such
Global Phase III Trial (up to the Patient Commitment) based on the Average Cost Per Patient in the Territory. If Lian does not participate in a Global Phase III Trial for either of Crohn’s disease or ulcerative colitis, then Lian will conduct a
Clinical Trial in the Territory intended to support the Regulatory Approval for the use of the Licensed Product in the applicable disease in the Territory, and such Clinical Trial will be included in the Territory-Specific Development Plan.
Additionally, in such event, Lian shall use good faith efforts to design the protocol for such Clinical Trial in a manner that would permit Landos to use clinical data generated from such Clinical Trial to support the Regulatory Approval for the use
of the Licensed Product in the applicable disease in the U.S. 


  

	 	(b)	 Other Global Trial Participation. In the event that Landos decides to conduct a Global Trial for a
Licensed Product, other than a Global Phase III Trial, that is primarily intended to support the Development or Regulatory Approval of any Compound or Licensed Product in the Field outside the Territory (each, an “Other Global
Trial”), to the extent the Parties agree to Lian’s participation in such Other Global Trial, then Lian will participate in such Other Global Trial and include Clinical Trial sites in the Territory, subject to (i) [***], (ii) [***], and
(iii) [***]. For any Other Global Trial in which Lian agrees to participate, the Parties will prepare an update to the Global Development Plan to include the Development activities to be conducted by Lian in the Territory in support of such Other
Global Trial, including the Clinical Trial sites in the Territory for such Other Global Trial, to be determined by Lian after considering in good faith Landos’ suggestions thereon. 



  
 20 














	 	(c)	 Study Design and Protocol. Landos will determine the study design and study protocol for any Global
Phase III Trial or Other Global Trial, and Lian will have the right to determine which patient types to enroll in the Territory for such Global Phase III Trial or Other Global Trial. Notwithstanding any provision to the contrary set forth in this
Agreement, to the extent that Lian participates in any such Global Phase III Trial or Other Global Trial, Lian’s obligation to participate in such Global Phase III Trial or Other Global Trial is subject to the Parties’ agreement on such
study design and study protocol (such approval of Lian not to be unreasonably withheld or delayed). 


  

	3.4	 Development Records and Reporting. 



 

	 	(a)	 Records. Lian will maintain complete and accurate records of all work conducted by Lian in furtherance
of seeking Regulatory Approval for the Licensed Product in the Field in the Territory. Such records will be maintained in sufficient detail and in good scientific manner appropriate for patent and regulatory purposes and in accordance with
applicable Laws. Lian will document all non-clinical studies and Clinical Trials for Licensed Products in formal written study records according to applicable Laws, including applicable national and
international guidelines such as ICH, GCP and GLP, and shall, at Landos’ written request, provide Landos English translations thereof (to the extent prepared and originated in a language other than English and subject to reimbursement by Landos
of any cost of translation thereof). To the extent permissible, Landos shall have the right to review and copy such records at reasonable times and to obtain access to the original to the extent necessary or useful for regulatory or patent purposes
in accordance with this Agreement. 


  

	 	(b)	 Reporting. Lian will provide a written report to the JSC for review and discussion, at least [***], in
English, summarizing Lian’s activities and progress related to the pursuit of Regulatory Approval for the Licensed Product in the Field in the Territory. 



 

	3.5	 Development Costs. Except as set forth in Section 3.3 (Global Trial Preparation) and this
Section 3.5 (Development Costs), each Party will bear 100% of the costs and expenses it incurs in connection with the Development activities conducted under the Development Plans. 



  
 21 














	3.6	 Regulatory Submissions and Approvals; Communications; Meetings. 



 

	 	(a)	 Regulatory Filings and Approvals. Lian, or its relevant Affiliates or Sublicensees, will have the sole
and exclusive right to file and hold all Regulatory Filings, and to apply for and maintain all Regulatory Approvals and Pricing and Reimbursement Approvals, in each case, for all Licensed Products in the Field in the Territory at Lian’s cost
and expense in the name of Lian or any of its Affiliates and Sublicensees. The Parties will use good faith efforts to cooperate to effectuate this Section 3.6(a) (Regulatory Filings and Approvals), and if, after the Parties’ use of good
faith efforts, Lian, or its Affiliate or Sublicensee [***]. Subject to the terms and conditions of this Agreement, Lian will be responsible, at its sole cost and expense, for all regulatory activities leading up to and including the obtaining of
Regulatory Approvals and any Pricing and Reimbursement Approvals, as applicable, for Licensed Products in the Field from Regulatory Authorities or Governmental Authorities in the Territory. Lian will conduct such activities (and any and all
regulatory activities delegated to Lian in this Agreement) (A) in its own name, if Lian is the legal and beneficial owner of the Regulatory Approvals for the Licensed Products in the Field in the Territory, [***]. 



 

	 	(b)	 Regulatory Communications. Subject to applicable Law and this Section 3.5 (Development Costs), Lian
will oversee, monitor, and manage all interactions and communications with Regulatory Authorities with respect to the Licensed Products in the Field in the Territory. Lian will have final decision-making authority regarding all regulatory activities
for the Licensed Products in the Field in the Territory, including the labeling strategy and the content of Regulatory Filings for Licensed Products. 


  

	 	(c)	 Regulatory Meetings. Until such time as Lian obtains Regulatory Approval for the Licensed Product in the
Field in the Territory, to the extent legally permissible and practicable, Lian will provide Landos with reasonable prior written notice of all substantive meetings with Regulatory Authorities regarding the Licensed Product if permitted by
applicable Law or the Regulatory Authority. Landos will have the right to request to be present as an observer at (but not to participate in, unless requested by Lian or the Regulatory Authority) all such meetings with Regulatory Authorities to the
extent permitted under applicable Law, at Landos’ sole cost and expense, and Lian will consider any such request in good faith.  


  

	3.7	 Termination or Suspension of Clinical Trials. Notwithstanding any provision to the contrary set forth in
this Agreement or the Pharmacovigilance Agreement, the Parties hereby agree that Lian may terminate or suspend any Clinical Trial relating to the Licensed Products in the Field in the Territory, and Landos may terminate or suspend any Global Trial,
without the approval or consent of the JSC or the other Party, if (i) a Regulatory Authority, institutional review board or safety data review board for such Clinical Trial has required or recommended such termination or suspension or
(ii) following review and discussion with the JSC, the Party seeking such termination believes in good faith that such termination or suspension is warranted because of observed safety risks to the study subjects. In either case, such
Party will promptly notify the other Party in writing of such termination or suspension.  


  

	3.8	 No Harmful Actions. Each Party will promptly notify the other Party of all material communications or
correspondence with Regulatory Authorities with respect to any Licensed Product in such Party’s territory that are (a) received by such Party or its Affiliates, Sublicensees, or other licensees (to the extent that such Party has the right
to disclose such material communications or correspondence of other licensees and provided that such Party uses commercially reasonable efforts to obtain such right from such other licensees) from any Regulatory Authority or submitted by such
Party, its Affiliates or other licensees to any Regulatory Authority and (b) would reasonably be expected to impact the other Party’s Development, Manufacture, or Commercialization of the Licensed Products in the Field in the




  
 22 














	 	
other Party’s territory. If either Party believes that the other Party is taking or intends to take any action with respect to a Licensed Product in such other Party’s territory that
could have a material adverse impact upon the regulatory status of any Licensed Product in such Party’s territory, then such Party will have the right to bring the matter to the attention of the JSC and the JSC will discuss in good faith a
resolution to such concern. 

  

	3.9	 Pharmacovigilance. Within [***] after the Effective Date, the Parties will negotiate in good faith and
finalize the actions that the Parties will employ with respect to the Licensed Products to protect patients and promote their well-being in a written pharmacovigilance agreement (the “Pharmacovigilance Agreement”). These
responsibilities will include mutually acceptable guidelines and procedures for the receipt, investigation, recordation, communication, and exchange (as between the Parties) of Adverse Event reports and any other information concerning the safety of
any Licensed Product, including recall and withdrawal responsibilities, processes and procedures. Such guidelines and procedures will be in accordance with, and enable the Parties to fulfill, local and national regulatory reporting obligations under
applicable Law. Furthermore, such agreed procedure will be consistent with relevant ICH guidelines, except where such guidelines may conflict with existing local regulatory reporting safety reporting requirements, in which case local reporting
requirement will prevail. Lian will be responsible for reporting quality complaints, Adverse Events, and safety data related to the Licensed Products in the Field to applicable Regulatory Authorities in the Territory, as well as responding to safety
issues and to all requests of Regulatory Authorities relating to Licensed Products in the Field in the Territory. Landos will be responsible for reporting quality complaints, Adverse Events, and safety data related to Licensed Product to applicable
Regulatory Authorities outside the Territory, as well as responding to safety issues and to all requests of Regulatory Authorities relating to Licensed Product outside the Territory. The Pharmacovigilance Agreement will also provide for a worldwide
safety database to be maintained by Landos at its sole cost and expense, which worldwide safety database will be accessible by Lian and its Affiliates, Sublicensees and contractors to the full extent necessary for Lian to exercise its rights under
this Agreement, comply with its obligations under this Agreement and comply with all applicable Law. Each Party will comply with its respective obligations under such Pharmacovigilance Agreement and will cause its Affiliates and Sublicensees and
contractors to comply with such obligations.

	4.2	 Two-Invoice Policy. The Parties agree that in the event, 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, the Parties will use reasonable efforts to discuss in good faith 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 the Parties as agreed under this Agreement. 



 

	4.3	 Manufacture Technology Transfer Option. At any time after the Effective Date, upon Lian’s written
request to Landos, and Landos’ written consent (such consent not to be unreasonably withheld or delayed) or, in the event of a Supply Failure, upon Lian’s written notice to Landos, (a) the Parties will discuss in good faith and
prepare a technology transfer plan pursuant to which Landos will (i) provide access, and transfer, to Lian or its designated CMO, at Lian’s sole cost (other than in the event that such transfer is following the occurrence of a Supply

of this Agreement to the extent agreed to in writing by the Parties. 


  

	5.3	 Membership. The JSC will be composed of a total of [***] representatives of each Party, which will be
appointed by each of Landos and Lian, respectively. Each individual appointed by a Party as a representative to the JSC will be an employee of such Party with sufficient seniority and decision-making authority within the applicable Party to provide
meaningful input and make decisions arising within the scope of the JSC’s responsibilities, and have knowledge and expertise in the Development and Commercialization of compounds and products similar to the Compound and Licensed Products under
this Agreement. The JSC may change its size from time to time by consent of its members, provided that the JSC will consist at all times of an equal number of representatives of each Party, unless otherwise agreed by the Parties in writing.
Each Party may replace any of its JSC representatives at any time upon written notice to the other Party, which notice may be given by e-mail, sent to the other Party’s
co-chairperson. The JSC will be co-chaired by one designated representative of each Party. The co-chairperson of the JSC will

unanimous agreement with respect to all matters within the JSC’s authority. Each Party’s representatives on the JSC will collectively have one vote, (the “Party Vote”) and no action or decision will be taken by the JSC
without unanimous Party Vote (i.e., the affirmative Party Vote of each Party). If the JSC is not be able to reach agreement with respect to a matter at a duly called meeting of the JSC, then either Party may refer such matter to the Senior
Officers for resolution, and the Senior Officers will attempt to resolve the matter in good faith. If the Senior Officers fail to resolve such matter within [***] Business Days after the date on which the matter is referred to the Senior Officers
(unless a longer period is agreed to by the Parties), then Lian will have the final decision-making authority as to (a) [***] and (b) [***], except [***], Landos will have the final decision-making authority with respect to such matter. Subject to

the Senior Officers as described above, will [***]. 


  

	5.6	 Limitations. Notwithstanding anything to the contrary, neither Party will have the final decision-making
authority on amending or updating the Development Plan in any way that would materially alter the scope of the other Party’s obligations hereunder, increase the other Party’s financial obligations hereunder, or result in the disclosure of
the Confidential Information of the other Party, in each case, without the other Party’s prior written consent. Notwithstanding any provision of this Article 5 (Governance; Joint Steering Committee) to the contrary, the JSC will not have the
authority to amend the terms or conditions of this Agreement.  


  

	5.7	 Alliance Managers. 



 

	 	(a)	 Appointment. Each Party will appoint a person to oversee interactions between the Parties for all
matters related to the Development and Commercialization of Licensed Products between meetings of the JSC (each, an “Alliance Manager”). The Alliance Managers will have the right to attend all meetings of the committees as non-voting participants and may bring to the attention of the JSC any matters or issues either Alliance Manager reasonably believes should be discussed and will have such other responsibilities as the Parties may
agree in writing. Each Party may replace its Alliance Manager at any time or may designate different Alliance Managers with respect to Development and Commercialization matters, respectively, by notice in writing to the other Party.




  
 27 














	 	(b)	 Responsibility. The Alliance Managers will have the responsibility of creating and maintaining a
constructive work environment within the JSC and between the Parties for all matters related to this Agreement. Without limiting the generality of the foregoing, each Alliance Manager will: 



 

	 	(i)	 provide a single point of communication within the Parties’ respective organizations and between the
Parties with respect to this Agreement; 


  

	 	(ii)	 coordinate cooperative efforts, internal communications and external communications between the Parties with

any Region in the Territory in which a Licensed Product is then being sold by Lian or an Affiliate or Sublicensee, then the applicable royalty rates in effect with respect to such Licensed Product in such Region as specified in Section 6.2(a)
(Royalty Rate) will be reduced by [***] for the remainder of the Royalty Term for such Licensed Product in such Region. 


  

	 	(c)	 Third Party Payments. If Lian makes a payment under any agreement with a Third Party pursuant to which
Lian obtains a license or other rights under a Patent Right or other Intellectual Property owned or controlled by such Third Party in a given Region (whether by acquisition or license) that is necessary or reasonably useful to Develop, Manufacture,
or Commercialize one or more Licensed Products in such Region, then Lian may offset against the Milestone Payments or royalties due to Landos for the Development and Commercialization of the Licensed Products in such Region covered by such license
or rights an amount equal to [***] of the amounts paid to such Third Party under such agreement (including any upfront payments, milestone payments, and royalties), in all cases, subject to Section 6.4(d) (Cumulative Deductions).




  
 30 














	 	(d)	 Cumulative Deductions. Notwithstanding the foregoing, in no event will the deductions set forth in
Section 6.3(a) (Expiration of Valid Claims) through Section 6.3(c) (Third Party Payments) reduce (i) the royalties otherwise payable to Landos as specified in Section 6.2(a) (Expiration of Valid Claims) or (ii) with respect
to the deductions set forth in Section 6.3(c) (Third Party Payments), the Milestone Payments otherwise payable to Landos as specified in Section 6.1(b) (Development Milestone Payment) and Section 6.1(c) (Sales Milestone Payments), in
each case, by more than [***]. To the extent the foregoing limitation limits the reduction Lian is permitted to take during a Calendar Quarter, Lian will be entitled to carryforward the amount of the reduction Lian was unable to take during such
Calendar Quarter and apply such amounts to royalties or Milestone Payments, as applicable, payable to Landos in future Calendar Quarters until such amount is applied by Lian in full. 



 

	6.4	 Audits. Each Party will maintain and will cause its Affiliates and all Sublicensees to maintain,
complete and accurate records in sufficient detail to permit the other Party to confirm the accuracy of the calculation of royalties, Milestone Payments, Fully Burdened Manufacturing Cost calculations, and other payments under this Agreement. Upon
reasonable prior notice, but not more than [***] per Calendar Year and not more than [***] with respect to any records, such records will be available during regular business hours for a period of [***] years from the end of the [***] to which they
pertain for examination at the expense of the requesting Party by an independent certified public accountant selected by the requesting Party and reasonably acceptable to the other Party, for the sole purpose of verifying the accuracy of the
financial reports and correctness of the payments furnished by the other Party pursuant to this Agreement. Any such auditor will not disclose the other Party’s Confidential Information, except to the extent such disclosure is necessary to
verify the accuracy of the financial reports furnished by the other Party or the amount of payments due by the other Party under this Agreement. The accountant’s report will be disclosed simultaneously to both Parties, and such report will be
the Confidential Information of each Party and subject to the terms of Article 8 (Confidentiality and Publicity). Any amounts shown to be owed but unpaid will be paid within [***] days from the accountant’s report. Any amounts shown to have
been overpaid will be refunded within [***] days from the accountant’s report. The requesting Party will bear the full cost of such audit unless such audit discloses an underpayment by the other Party of more than [***] of the amount due, in
which case the other Party will bear the full cost of such audit. The audit rights in this Section 6.4 (Audits) will survive the Term for [***] following the effective date of any termination or expiration of this Agreement.



  

	6.5	 Tax Withholding. 



 

	 	(a)	 In the event any withholding, value added, or other tax (including any tax based on income to Landos)
(“Tax Withholdings”) is required to be withheld and deducted from payments by Lian (or its Affiliate paying on behalf of Lian) pursuant to this Agreement under applicable Laws, notwithstanding any provision to the contrary set forth
under this Agreement, Lian (or its Affiliate paying on behalf of Lian) will make such deduction and withholding [***], and any amounts so withheld and deducted will be remitted by Lian (or its Affiliate paying on behalf of Lian) on a timely basis to
the appropriate Governmental Authority for the account of Landos and Lian (or its Affiliate paying on behalf of Lian) will provide Landos reasonable evidence of the remittance within [***] days thereof and for the purposes of this Agreement, Lian
will be deemed to have fulfilled all of its payment obligations to Landos with respect to such payments paid to the such Governmental Authority. Lian may satisfy its withholding, value added or other tax obligations under this Section 6.6
(Currency of Payments) through its Affiliates. 



  
 31 














	 	(b)	 If as a result of any assignment, transfer by operation of law or other transfer (A) of this Agreement by
Lian to an Affiliate or Third Party, or (B) some or all of the rights and obligations under this Agreement to an Affiliate or Third Party (in each case of (A) and (B), a “Transfer”), then the Tax Withholdings exceeds the
Tax Withholdings that would have resulted in the absence of a Transfer, then [***]. 


  

	 	(c)	 Without limiting Section 6.6(a), the Parties agree to cooperate with one another and use reasonable
efforts to reduce or eliminate Tax Withholdings or similar obligations in respect of payments made by Lian to Landos under this Agreement. Landos shall provide Lian any tax forms that may be reasonably necessary in order for Lian or its Affiliates
not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Each Party shall provide the other Party and its Affiliates with reasonable assistance to enable the recovery, as permitted by applicable Laws,
of withholding taxes, VAT or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or VAT. Specifically, in the event that any tax has been withheld upon
a payment made under this Agreement and been remitted by Lian to a Governmental Authority, if requested by Landos and if, and for so long as, the Parties acting in good faith mutually agree that there is a reasonable prospect of successfully
obtaining a refund of such tax, then Lian shall, at Landos’ sole cost and expense, seek a refund of such tax from the proper Governmental Authority. Landos agrees to reasonably cooperate with Lian and its Affiliates in the pursuit of such tax
refund (including, if required by applicable Laws or by the applicable Governmental Authority, permitting Lian to seek such tax refund in Landos’ name and participating in any application or appeal that requires that Landos be the party
applying for such tax refund, solely with Landos ‘prior written consent); provided that, Landos agrees to assume responsibility for direct payment of lawyers’ and other advisors’ fees and any other costs associated with seeking such
refund. 


  

	6.6	 Manner of Payment; Currency of Payments. All payments owed by Lian under this Agreement will be made by
wire transfer in immediately available funds to a bank and account designated in writing by Landos. All amounts payable and calculations under this Agreement will be in Dollars. As applicable, Net Sales and any royalty reductions will be translated
into Dollars using the average of the applicable daily foreign exchange rates published in the Wall Street Journal (or any other qualified source that is acceptable to both Parties) for [***] in which such Net Sales occurred.



  

	6.7	 Late Payments. Without limiting any other rights or remedies available to Landos hereunder, any late
payment by Lian will bear interest, to the extent permitted by Laws, at an annual rate of [***] or the highest rate permitted by applicable Law (whichever is lower), computed from the dated such payment was due until the date Lian makes the payment,
with such interest compounded [***]. 


 ARTICLE 7 

INTELLECTUAL PROPERTY OWNERSHIP, 

PROTECTION AND RELATED MATTERS 
  

	7.1	 Ownership of Inventions. 



 

	 	(a)	 Ownership of Inventions; Cross License of Product Inventions. Ownership will follow inventorship for any
and all inventions, Know-How, developments, or discoveries, whether patentable or non-patentable, invented or otherwise developed or generated by either Party alone
(including its Affiliates, or any of its or their employees, Sublicensees, independent contractors, or agents) or jointly by both Parties (including jointly by their Affiliates, or any of its or their employees, Sublicensees, independent
contractors, or agents) in the performance of a Party’s obligations or exercise of its rights under this Agreement (collectively, “Inventions”) and such ownership will be determined based on the principles of inventorship in
accordance with United States patent Laws. 



  
 32 














	 	(b)	 Assignment Obligation. Each Party will assign, and will cause its Affiliates to assign, its rights, and
cause all employees of such Party or Affiliate who perform activities for such Party or Affiliate under this Agreement to be under an obligation to assign their rights, in any Patent Rights and Know-How,
whether or not patentable, resulting therefrom to such Party or Affiliate to effectuate the terms and conditions set forth in Section 7.1(a) (Assignment Obligation). With respect to any activities of a Party or its Affiliate or exercise of its
or their rights under this Agreement that are subcontracted to a Person that is not an employee, the Party or such Affiliate retaining such subcontractor will include in the applicable subcontract an assignment to such Party or such Affiliate of all
rights in Patent Rights and Know-How made by such subcontractor resulting from such activities or exercise of its rights, and in any event will include in the applicable subcontract a license to such Party or
Affiliate that is sublicensable (through multiple tiers) to the other Party under this Agreement, of any Patent Rights and Know-How made by such contractor or subcontractor resulting from such activities.



  

	7.2	 Prosecution and Maintenance of the Licensed Patent Rights and Joint Patent Rights.



  

	 	(a)	 In the Territory. As between the Parties, Landos will have the first right, at its expense, to Prosecute
the Licensed Patent Rights and Joint Patent Rights in all Regions in the Territory, at Landos’ sole cost and expense. Landos will keep Lian reasonably informed of all steps with regard to and the status of such Prosecution of such Patent
Rights, including by providing Lian with (i) copies of all correspondence and material communications it sends to or receives from any patent office or agency in the Territory relating to such Patent Rights, (ii) a draft copy of all
applications, in each case ((i) and (ii)), sufficiently in advance of filing or response to permit reasonable review and comment by Lian, and (iii) a copy of applications as filed, together with notice of its filing date and serial number.
Before Landos submits any material filing, including a new patent application, or response to such patent authorities with respect to any Licensed Patent Rights or Joint Patent Rights, Landos will provide Lian with a reasonable opportunity to review
and comment on such filing or response and will incorporate any reasonable comments or suggestions provided by Lian regarding the Prosecution of such Licensed Patent Rights or Joint Patent Rights under this Section 7.2(a) (In the Territory).



  

	 	(b)	 Step-In Right. If Landos elects not to continue to Prosecute a
given Patent Right within the Licensed Patent Rights or Joint Patent Rights in the Territory pursuant to Section 7.2(a) (In the Territory), then Landos will give Lian notice thereof within a reasonable period (but not less than [***]) prior to
allowing such Patent Rights to lapse or become abandoned or unenforceable, and Lian will have the right, but not the obligation, to assume the Prosecution of such Patent Rights in such Region, including paying any required fees to maintain such
Patent Rights in such Region, all at Lian’s sole expense and through patent counsel or agents of its choice. Upon transfer of Landos’ responsibility for Prosecuting any of the Patent Rights to Lian under this Section 7.2(b) (Step-In Right), (i) Landos will promptly deliver to Lian copies of all necessary files related to the Patent Rights with respect to which responsibility has been transferred and will take all actions and execute
all documents reasonably necessary for Lian to assume such Prosecution, and (ii) such Patent Right shall no longer extend the Royalty Term pursuant to Section 6.2(b) (Royalty Term). Thereafter, Lian will keep Landos reasonably informed of
the status of such Prosecution of such Patent Rights. 



  
 33 














	 	(c)	 Cooperation. Each Party will, and will cause its Affiliates to, reasonably cooperate, with the other
Party with respect to the Prosecution of Licensed Patent Rights and Joint Patent Rights pursuant to this Section 7.2 (Prosecution and Maintenance of the Licensed Patent Rights and Joint Patent Rights), including with respect to obtaining patent
term restoration, supplemental protection certificates or their equivalents, and patent terms extension with respect to the Licensed Patent Rights and Joint Patent Rights in any Region where applicable. 



 

	7.3	 Third Party Infringement. 



 

	 	(a)	 Notice. Each Party will promptly notify the other in writing if such Party becomes aware of any
suspected, threatened or actual infringement by any Third Party of any Licensed Technology or Joint Patent Right arising from the making, using, offering to sell, selling, or importing of a product in the Field in the Territory that could be
competitive with a Licensed Product, and, in each case, will provide the other Party with all evidence in such Party’s possession or control supporting such infringement or unauthorized use or misappropriation (each, an
“Infringement”). 


  

	 	(b)	 Lian First Right. As between the Parties, Lian will have the first right, but not the obligation,
using counsel of its choosing and at its sole expense, to institute any infringement, misappropriation, or other appropriate Action against any Infringement of the Licensed Technology or Joint Patent Rights (any such Action, an “Infringement
Action”) in the Field in the Territory. Landos shall have the right, at its own cost and expense, to be represented in any Infringement Action by counsel of its own choice. Lian will notify Landos of its decision to commence an Infringement
Action, will keep Landos apprised in writing of any such Infringement Action, and will consider Landos’ reasonable interests and requests regarding such Infringement Action. 



 

	 	(c)	 Landos Right. If Lian fails to commence a suit to enforce the Licensed Technology or Joint Patent
Rights against such Infringement (or to settle or otherwise secure the abatement of such Infringement) within (i) [***] after its receipt or delivery of notice under Section 7.3 (Third Party Infringement), or (ii) [***] before the time limit,
if any, set forth in the appropriate Laws for the filing of such actions, whichever comes first, or ceases to diligently pursue such Infringement Action, then Landos will have the right, but not the obligation, at its own expense to institute such
Infringement Action against the applicable Third Party infringer(s). 


  

	 	(d)	 Cooperation. In any Infringement Action brought under the Licensed Technology or Joint Patent Rights
pursuant to Section 7.3(b) (Lian First Right) and Section 7.3(c) (Landos Right), each Party will, and will cause its Affiliates to, reasonably cooperate with each other, in good faith, relative to the other Party’s efforts to protect
the Licensed Technology and Joint Patent Rights, and will join such suit as a party, if requested by the other Party. Furthermore, the Party initiating any Infringement Action pursuant to Section 7.3(b) (Lian First Right) or Section 7.3(c)
(Landos Right) will consider in good faith all reasonable and timely comments from the other Party on any proposed arguments asserted or to be asserted in litigation related to the enforcement or defense of any such Patent Rights. Neither Party will
have the right to settle any Infringement Action under this Section 7.3 (Third Party Infringement) in a manner that diminishes the rights or interests of the other Party under this Agreement without the consent of such other Party, which
consent will not be unreasonably withheld. 


  

	 	(e)	 Allocation of Recoveries. Any settlements, damages or monetary awards recovered by either Party pursuant
to any Infringement Action will (i) first be allocated to reimbursing the Parties for their reasonable out-of-pocket expenses in making such recovery (which amounts
will be allocated pro rata if insufficient to cover the totality of such expenses), and (ii) [***]. 


  

  
 34 














	7.4	 Claimed Infringement. Each Party will promptly notify the other Party if a Third Party brings any Action
alleging patent infringement by Lian or Landos or any of their respective Affiliates or Sublicensees with respect to the Development, Manufacture or Commercialization of any Licensed Product or Joint Patent Rights (any such Action, an
“Infringement Claim”) in the Territory. Lian will have the right, but not the obligation, to control the defense and response to any such Infringement Claim in the Territory with respect to Lian’s activities, at Lian’s
sole cost and expense, and Landos will have the right, at its own expense, to be represented in any such Infringement Claim in the Territory by counsel of its own choice. Landos will have the sole right, but not the obligation, to control the
defense and response to any such Infringement Claim with respect to Landos’ activities, including any such Infringement Claim in the Territory 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 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 7.4 (Claimed Infringement) 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, neither Party will have the right to settle any Infringement Claim under this Section 7.4 (Claimed
Infringement) in a manner that diminishes the rights or interests of the other Party under this Agreement without the consent of such other Party, which consent will not be unreasonably withheld. 



 

	7.5	 Common Interest. All information exchanged between the Parties regarding the Prosecution, enforcement,
and defense, of Licensed Patent Rights and Joint Patent Rights under this Article 7 (Intellectual Property Ownership, Protection and Related Matters) will be deemed Confidential Information of the disclosing Party. In addition, the Parties
acknowledge and agree that, with regard to such Prosecution, enforcement, and defense, the interests of the Parties as collaborators and licensor and licensee are to obtain the strongest patent protection possible, and as such, are aligned and are
legal in nature. The Parties agree and acknowledge that they have not waived, and nothing in this Agreement constitutes a waiver of, any legal privilege concerning the Patent Rights under this Article 7 (Intellectual Property Ownership, Protection
and Related Matters), including privilege under the common interest doctrine and similar or related doctrines. Notwithstanding any provision to the contrary set forth in this Agreement, to the extent a Party has a good faith belief that any
information required to be disclosed by such Party to the other Party under this Article 7 (Intellectual Property Ownership, Protection and Related Matters) is protected by attorney-client privilege or any other applicable legal privilege or
immunity, such Party will not be required to disclose such information, and the Parties will in good faith cooperate to agree upon a procedure (including entering into a specific common interest agreement, disclosing such information on a “for
counsel eyes only” basis or similar procedure) under which such information may be disclosed without waiving or breaching such privilege or immunity.

 ARTICLE 8 

CONFIDENTIALITY AND PUBLICITY 
  

	8.1	 Confidential Information. 



 

	 	(a)	 Confidentiality Obligation. During the Term and for a period of [***] years after any termination or
expiration of this Agreement, each Party agrees to, and will cause its Affiliates and Sublicensees and contractors to, keep in confidence and not to disclose to any Third Party, or use for any purpose, except to exercise its rights or perform its
obligations under this Agreement, any Confidential Information of the other Party, without the prior written consent of such disclosing Party. The existence and terms of this Agreement are the Confidential Information of each Party.



  

	 	(b)	 Permitted Disclosures. Each Party agrees that it and its Affiliates will provide or permit access to the
other Party’s Confidential Information only to the receiving Party’s employees, consultants, advisors, licensees, collaboration partners, and Sublicensees, and to the employees, consultants and advisors of the receiving Party’s
Affiliates, in each case on a need to know basis who are subject to obligations of confidentiality and non-use with respect to such Confidential Information no less stringent than the obligations of
confidentiality and non-use of the receiving Party pursuant to this Section 8.1 (Confidential Information). Each Party will remain responsible for any failure by its Affiliates, licensees, collaboration
partners, or Sublicensees, and its and its Affiliates’ respective employees, consultants and advisors, to treat such Confidential Information as required under this Section 8.1 (Confidential Information) as if such Affiliates, employees,
consultants, advisors, licensees, collaboration partners, and Sublicensees were parties directly bound to the requirements of this Section 8.1 (Confidential Information). 



 

	 	(c)	 Confidentiality Limitation. Notwithstanding any provision to the contrary set forth in this Agreement,
each Party may use and disclose the other Party’s Confidential Information as follows: (i) under appropriate written confidentiality and non-use obligations no less stringent than those in this
Agreement, to its Affiliates, bona fide potential or actual collaboration partners, licensors, Sublicensees, licensees, or strategic partners and to employees, directors, agents, consultants, and advisers of any other Third Parties,
(ii) to its financial advisors, attorneys and accountants, bona fide actual or potential acquisition partners, financing sources or investors and underwriters on a need to know basis, in each case under appropriate confidentiality and non-use obligations (which may include professional ethical obligations) no less stringent than those in this Agreement; provided, however, that each Party will remain responsible for any failure by
any of the foregoing individuals to treat such Confidential Information as required under Section 8.1 (Confidential Information) as if such individuals were parties directly bound to the requirements of this Section 8.1 (Confidential
Information), or (iii) as required by any court or other governmental body or as otherwise required by applicable Laws (including any such disclosures as are required by a Regulatory Authority in connection with seeking Regulatory Approval,
Pricing and Reimbursement Approval, import authorization for any Licensed Product in the Territory, or the rules or regulations of the United States Securities and Exchange Commission or similar Regulatory Authority in a country other than the
United States or of any stock exchange or listing entity (including in connection with the public sale of securities)); provided, that, notice is promptly given to the other Party and the disclosing Party cooperates with reasonable
requests from the other Party to seek a protective order or other appropriate remedy to protect the Confidential Information. Notwithstanding any provision to the contrary contained in this Article 8 (Confidentiality and Publicity), Confidential
Information that is permitted or required to be disclosed will remain otherwise subject to the confidentiality and non-use provisions of Section 8.1(b) (Permitted Disclosures) and this Section 8.1(c)
(Confidentiality Limitation). If either Party concludes that a copy of this Agreement must be filed with the United States Securities and Exchange Commission or similar Governmental Authority in a country other than the United States, then such
Party will, a reasonable time prior to any such filing, provide the other Party with a copy of such 



  
 36 














	 	
agreement showing any provisions hereof as to which the Party proposes to request confidential treatment, will provide the other Party with an opportunity to comment on any such proposed
redactions and to suggest additional redactions, and will take such Party’s reasonable comments into consideration before filing such agreement and use reasonable efforts to have terms identified by such other Party afforded confidential
treatment by the applicable Regulatory Authority. 

  

	 	(d)	 Secrecy of Licensed Know-How. Without limiting the generality of
Section 8.1(a) (Confidentiality Obligation), during the Term the receiving Party will protect, and will cause, to the extent applicable, its Affiliates and Sublicensees, and its and their respective officers, directors, employees, and agents to
protect, the secrecy and confidentiality of the Licensed Know-How and unpublished Patent Rights using at least the same degree of care as it uses to prevent the disclosure of its own other confidential
information of like importance and in any event a reasonable duty of care. 


  

	 	(e)	 Residual Knowledge. The Parties acknowledge the practical difficulty of policing the use of information
inadvertently retained in the unaided memory of a receiving Party or its Affiliates and its and their officers, directors, employees, and agents who have had rightful access to the Confidential Information of the disclosing Party (“Residual
Knowledge”), and as such each Party agrees that the receiving Party will not be liable for the inadvertent use (without reference to any Confidential Information of the disclosing Party) by any of its or its Affiliates’ officers,
directors, employees, or agents of the Residual Knowledge that is inadvertently retained in the unaided memory of such officer, director, employee, or agent; provided that such officer, director, employee, or agent has not been directed to or
otherwise intentionally memorized or retained such Residual Knowledge for use other than as explicitly permitted under this Agreement. The receiving Party acknowledges and agrees that any use made by the receiving Party of any such Residual
Knowledge is on an “as is, where is” basis and at its sole risk, with all faults and all representations and warranties disclaimed by the disclosing Party. 



 

	8.2	 Publicity. The Parties acknowledge the importance of supporting each other’s efforts to publicly
disclose results and significant developments regarding the Licensed Product in the Field in the Territory, and each Party may make such disclosures from time to time, subject to the terms and conditions of this Agreement, including this
Section 8.2 (Publicity). Such disclosures may include achievement of milestones, significant events in the Development process with respect to Licensed Products, or Commercialization activities with respect to Licensed Products.



  

	 	(a)	 On a date to be agreed by the Parties, the Parties will jointly issue a press release regarding the signing of
this Agreement. Except as set forth in the preceding sentence and for disclosures permitted in accordance with Section 8.1(b) (Permitted Disclosures), whenever either Party elects to make any public disclosure regarding milestones or other
significant events in the Development or Commercialization of the Licensed Products in the Field in the Territory, it will first notify the other Party of such planned press release or public announcement and provide a draft for review no less than
[***] in advance of issuing such press release or making such public announcement (or, with respect to press releases and public announcements that are required by applicable Laws, with as much advance notice as possible under the circumstances if
it is not possible to provide notice at least [***] in advance). Each Party will have the right to review and approve any such planned press release or public announcement proposed by the other Party with respect to Licensed Products in the Field in
the Territory, or that includes Confidential Information of the other Party. In such case, (i) the reviewing Party will attempt to provide such approval as soon as reasonably possible and will not unreasonably withhold such approval;
(ii) the 



  
 37 














	 	
reviewing Party will provide explanations of its disapproval of such press release; and (iii) a Party desiring to make such public disclosure may issue such press release or public
announcement without such prior review by the other Party if (A) the contents of such press release or public announcement have previously been made public other than through a breach of this Agreement by such Party, and (B) such press
release or public announcement is consistent with the previously issued press release or other publicly available information. The Party reviewing a press release provided under this clause (i) of this Section 8.2(a) (Publicity) will
review and approve or disapprove such press release within [***] Business Days after its receipt thereof. 

  

	 	(b)	 In the event that either Party proposes to publish or present the results of Development or Commercialization
carried out on the Licensed Product, including any oral presentation or abstract that contain clinical data or pertain to results of Clinical Trials or other studies, such publication or presentation will be subject to the prior review by the other
Party for protection of such other Party’s Confidential Information. Each Party will provide to the other Party the opportunity to review a draft of any proposed publication that covers the results of Development or Commercialization of
Licensed Products during the Term, and the submitting Party will remove from such proposed publication any Confidential Information of the other Party as reasonably requested by the other Party.

 ARTICLE 10 

INDEMNIFICATION; DAMAGES 
  

	10.1	 Indemnification by Landos. Landos will defend, indemnify and hold harmless Lian, its Affiliates
and their respective directors, officers, employees and agents (each, a “Lian Indemnified Party”), from, against and in respect of any and all Third Party Losses incurred or suffered by any Lian Indemnified Party to the
extent arising from or relating to: (a) any breach of any representation or warranty made by Landos in this Agreement, or any breach by Landos of any obligation, covenant, or agreement in this Agreement; (b) the gross negligence or
intentional misconduct of Landos or any of its Affiliates, (sub)licensees (other than Lian), or contractors, or any of their respective directors, officers, employees, or agents, in performing Landos’ obligations or exercising Landos’
rights under this Agreement; (c) activities conducted by or on behalf of Landos or its Affiliates or Sublicensees or contractors related to the Development, Manufacture, or Commercialization of Licensed Products anywhere in the world prior to
the Effective Date; and (d) the Development, Manufacture, or Commercialization of the Licensed Products by or on behalf of Landos, any of its Affiliates, Sublicensees (other than Lian), or contractors outside the Territory;
provided, however, that Landos’ obligations pursuant to this Section 10.1 (Indemnification by Landos) will not apply to the extent such Third Party Losses result from Third Party Losses for which Lian has an
obligation to indemnify Landos pursuant to Section 10.2 (Indemnification by Lian). 


  

	10.2	 Indemnification by Lian. Lian will defend, indemnify and hold harmless Landos, its Affiliates,
and each of their respective directors, officers, employees and agents (each, a “Landos Indemnified Party”) from, against and in respect of any and all Third Party Losses incurred or suffered by any Landos Indemnified Party
to the extent arising from or relating to: (a) any breach of any representation or warranty made by Lian in this Agreement, or any breach by Lian of any obligation, covenant, or agreement in this Agreement, (b) the gross negligence or
intentional misconduct of, or violation of Laws by, Lian, any of its Affiliates, Sublicensees, or contractors, or any of their respective directors, officers, employees, or agents, in performing Lian’s obligations or exercising Lian’s
rights under this Agreement, or (c) the Development, Manufacture, or Commercialization of the Licensed Product by or on behalf of Lian or its Affiliates or Sublicensees (other than Landos) or contractors; provided, however, that
Lian’s obligations pursuant to this Section 10.2 (Indemnification by Lian) will not apply to the extent such Third Party Losses result from Third Party Losses for which Landos has an obligation to indemnify Lian pursuant to
Section 10.1 (Indemnification by Landos). 


  

	10.3	 Claims for Indemnification. 



 

	 	(a)	 Notice. An Indemnified Party entitled to indemnification under Section 10.1 (Indemnification by
Landos) or Section 10.2 (Indemnification by Lian) will give prompt written notification to the Indemnifying Party from whom indemnification is sought of the commencement of any Action by a Third Party for which indemnification may be sought (a
“Third Party Claim”) or, if earlier, upon the assertion of such Third Party Claim by a Third Party; provided, however, that failure by an Indemnified Party to give notice of a Third Party Claim as provided in this
Section 10.3(a) (Notice) 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. 



  
 42 














	 	(b)	 Defense. Within [***] days after delivery of a notice of any Third Party Claim in accordance with
Section 10.3(a) (Notice), the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such Third Party Claim with counsel reasonably satisfactory to the Indemnified Party. If the
Indemnifying Party does not assume control of such defense, then the Indemnified Party may control such defense (with counsel reasonably selected by the Indemnified Party and approved by the Indemnifying Party, such approval not to be unreasonably
withheld). The Party not controlling such defense may participate therein at its own expense. 


  

	 	(c)	 Cooperation. The Party controlling the defense of any Third Party Claim will keep the other Party
advised of the status and material developments of such Third Party 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 Third Party Claim, with all out-of-pocket costs of such cooperation to be borne by the Party
controlling such defense. 


  

	 	(d)	 Settlement. The Indemnified Party will not agree to any settlement of such Third Party Claim without the
prior written consent of the Indemnifying Party, which consent will not be unreasonably withheld. The Indemnifying Party will not agree to any settlement of such Third Party Claim or consent to any judgment in respect thereof that does not include a
complete and unconditional release of the Indemnified Party from all liability with respect thereto or that imposes any liability or obligation on the Indemnified Party (other than a monetary obligation on the Indemnifying Party), without the prior
written consent of the Indemnified Party, which will not be unreasonably withheld (unless such compromise or settlement involves (i) any admission of legal wrongdoing by the Indemnified Party, (ii) any payment by the Indemnified
Party that is not indemnified under this Agreement, or (iii) the imposition of any equitable relief against the Indemnified Party (in which case, (i) through (iii), the Indemnified Party may withhold its consent to such
settlement in its sole discretion)). 


  

	 	(e)	 Mitigation of Loss. Each Indemnified Party will take and will procure that its Affiliates and
Sublicensees take all such reasonable steps and actions as are necessary or as the Indemnifying Party may reasonably require in order to mitigate any Third Party Claims (or potential losses or damages) under this Article 10 (Indemnification;
Damages). Nothing in this Agreement will or will be deemed to relieve any Party of any common law or other duty to mitigate any losses incurred by it. 


  

	10.4	 Insurance. Each Party, at its own expense, will maintain liability insurance (or self-insure) with
respect to its activities under this Agreement in an amount consistent with industry standards. Each Party will provide a certificate of insurance (or evidence of self-insurance) evidencing such coverage to the other Party upon request. Without
limiting the foregoing, during the Term and thereafter for the period of time required below, each Party will maintain on an ongoing basis comprehensive general liability insurance policies which are consistent with normal business practices of
prudent companies similar situated in such Party’s territory. Not later than [***] days following receipt of written request from a Party, the other Party will provide to the requesting Party a certificate of insurance evidencing such insurance
policies. Each Party will maintain such insurance or self-insurance coverage without interruption during the Term and for a period of [***] thereafter, and, if applicable, will provide certificates or letters evidencing such insurance coverage
without interruption as reasonably requested during the period of time for which such coverage must be maintained. Each Party will be provided at least [***] days’ prior written notice of any cancellation or material decrease in the other
Party’s insurance coverage limits described above. Notwithstanding the foregoing, either Party’s failure to maintain adequate insurance will not relieve that Party of its obligations set forth in this Agreement.

PUBLICITY); OR (C) FOR INDEMNIFIABLE LOSSES PURSUANT TO SECTION 10.1 (INDEMNIFICATION BY LANDOS) OR SECTION 10.2 (INDEMNIFICATION BY LIAN), AS APPLICABLE. 



ARTICLE 12

TERMINATION 
  

	12.1	 Term. Unless terminated earlier in accordance with this Article 12 (Term and Termination), this
Agreement will become effective as of the Effective Date and will continue in full force, on a Licensed Product-by-Licensed and Region-by-Region basis, until the expiration of the Royalty Term applicable to such Licensed Product and such Region (the “Term”).  



 

	12.2	 Paid-Up License Upon End of Royalty Term. Upon the
expiration of the Royalty Term for a given Licensed Product in a given Region in the Territory, the licenses and rights of reference granted to Lian pursuant to Section 2.1 (License Grants; Rights of Reference) will become perpetual,
irrevocable, fully paid-up, royalty free, fully sublicensable, and transferable with respect to such Licensed Product in such Region. 



 

	12.3	 Early Termination. 



 

	 	(a)	 Termination for Material Breach. Upon (i) any material breach of this Agreement by Landos or
(ii) any material breach of this Agreement by Lian (the Party so allegedly breaching being the “Breaching Party”), the other Party (the “Non-Breaching Party”) will have
the right, but not the obligation, to terminate this Agreement by providing written notice to the Breaching Party within [***] days’ in the case of a payment breach, or [***] days’ in the case of any other material breach, which notice
will, in each case (A) expressly reference this Section 12.3(a) (Termination for Material Breach), (B) reasonably describe the alleged breach that is the basis of such termination, and (C) clearly state the Non-Breaching Party’s intent to terminate this Agreement if the alleged breach is not cured within the applicable cure period. If such breach relates solely to one or more Licensed Products or Regions of the
Territory, then the non-breaching Party will have the right to terminate this Agreement solely with respect to such Licensed Product(s) or Region(s), as applicable. Notwithstanding the




  
 44 














	 	
foregoing, if such material breach, by its nature, is curable, but is not reasonably curable within the applicable cure period, then such cure period will be extended by up to an additional [***]
days if the Breaching Party provides a reasonable written plan for curing such breach to the Non-Breaching Party and uses reasonable efforts to cure such breach in accordance with such written plan. In
addition, if the Breaching Party disputes (A) whether it has materially breached this Agreement, (B) whether such material breach is reasonably curable within the applicable cure period, or (C) whether it has cured such material
breach within the applicable cure period, then the dispute will be resolved pursuant to Article 13 (Dispute Resolution), and the applicable cure period will be tolled during the pendency of such dispute resolution procedure. 


 

	 	(b)	 Termination for Patent Challenge. Except to the extent the following is unenforceable under the Laws of
a particular jurisdiction in the Territory or as otherwise provided in this Section 12.3(b) (Termination for Patent Challenge), Landos may terminate this Agreement upon written notice to Lian if Lian, its Affiliates, or Sublicensees,
individually or in association with any other person or entity, commences a legal action challenging the validity, enforceability, or scope of any Licensed Patent Rights in a court or other governmental agency of competent jurisdiction in the
Territory, including a reexamination or opposition proceeding (a “Patent Challenge”); provided that, if Lian or its Affiliate or Sublicensee withdraws (or causes to be withdrawn) such Patent Challenge within [***] days
after being requested to do so by Landos in writing (which termination notice will be deemed a request), then Landos will have no right to terminate this Agreement pursuant to this Section 12.3(b) (Termination for Patent Challenge). In
addition, and notwithstanding any provision to the contrary set forth in this Agreement, Landos may not terminate this Agreement pursuant to this Section 12.3(b) (Termination for Patent Challenge) (i) if Lian or its Affiliate or
Sublicensee is required by legal process to be joined as a party in any Patent Challenge by a Third Party, or (ii) with respect to: (A) any affirmative defense or other validity, enforceability, or
non-infringement challenge, whether in the same action or in any other agency or forum of competent jurisdiction, advanced by Lian, or any of its Affiliates or Sublicensees in response to any claim or action
brought in the first instance by, or on behalf of, Landos, (B) any Patent Challenge to the extent commenced by a Third Party that after the Effective Date acquires or is acquired by Lian or any of its Affiliates or its or their business or
assets, whether by stock purchase, merger, asset purchase, or otherwise; provided that such proceeding commenced prior to the closing of such acquisition, or (C) any Patent Challenge that is commenced by a Sublicensee;
provided that Lian demands that such Sublicensee withdraw such Patent Challenge promptly after Lian becomes aware of such Patent Challenge and terminates the sublicense agreement with the applicable Sublicensee if such Sublicensee does
not withdraw such Patent Challenge within [***] days after receipt of notice from Lian. 


  

	 	(c)	 Termination for Insolvency. Subject to Section 2.6 (Rights in Bankruptcy), either Party may
terminate this Agreement upon delivery of written notice to the other Party if (i) such other Party files in any court or agency pursuant to any statute or regulation of any jurisdiction a petition in bankruptcy or insolvency or for
reorganization or similar arrangement for the benefit of creditors or for the appointment of a receiver or trustee of such other Party or its assets, (ii) such other Party is served with an involuntary petition against it in any insolvency
proceeding and such involuntary petition has not been stayed or dismissed within [***] days of its filing, or (iii) such other Party makes an assignment of substantially all of its assets for the benefit of its creditors. 



 

	 	(d)	 Termination by Lian for Convenience. Lian may, upon [***] days’ prior written notice
to Landos, terminate this Agreement for convenience, without cause, and for any or no reason, on a Licensed Product-by-Licensed Product basis. 



  
 45 














	12.4	 Effects of Termination. 



 

	 	(a)	 Effects of Termination Generally. Upon any termination of this Agreement with respect to one or more
Licensed Products (a “Terminated Product”) or Regions (a “Terminated Region”), then the Parties’ rights, licenses and obligations under this Agreement will terminate with respect to the applicable Terminated
Product or Terminated Region and neither Party will have any further rights or obligations under this Agreement from and after the effective date of termination with respect to the applicable Terminated Product or Terminated Region, except as set
forth in this Section 12.4 (Effects of Termination). 


  

	 	(b)	 Winding Down of Activities. If there are any on-going
Development or Commercialization activities with respect to a Terminated Product or Terminated Region at termination or expiration of this Agreement, then the Parties will negotiate in good faith and adopt a plan to wind-down such activities in an
orderly fashion or, at Landos’ election and unless prohibited by any Regulatory Authority or applicable Law, promptly transition such activities from Lian to Landos or its designee, with due regard for patient safety and the rights of any
subjects that are participants in any Clinical Trials of the Licensed Products, and take any actions it deems reasonably necessary or appropriate to avoid any human health or safety problems and, with respect to any Clinical Trial transitioned to
Landos or its designee, to minimize any disruption to such Clinical Trial, and in compliance with all applicable Law. 


  

	 	(c)	 License Grant to Landos. 



 

	 	(i)	 Upon termination of this Agreement, Lian, on behalf of itself and its Affiliates hereby grants (effective on
delivery of the notice of termination) to Landos a worldwide, irrevocable, perpetual, transferable, exclusive license under the Product Inventions and Patent Rights controlled by Lian that cover any such Product Inventions, in each case, in
existence as of the applicable effective date of termination, to Develop, Manufacture, and Commercialize Compounds and Licensed Products in the Field in the Territory (the “Reversion License”). If any rights granted by Lian under
the Reversion License are Controlled by Lian or its Affiliates or Sublicensees pursuant to an agreement with a Third Party, then Landos will pay all amounts due under any such agreement to the extent reasonably allocable to Landos’ exercise of
the rights granted thereunder.

Lian that are specific to such Terminated Product for the purpose of Commercializing such Terminated Product, together with all goodwill associated with the specific Trademarks. If this Agreement is terminated with respect to one or more, but not
all, Regions in the Territory, then Lian will grant an exclusive license to Landos under any Trademarks in the Terminated Region owned or Controlled by Lian or its Affiliates that are specific to such Terminated Product for the purpose of
Commercializing such Terminated Product in the Terminated Region. 


  

	 	(iii)	 If Landos or its or their Affiliates or Sublicensees exercises the Reversion License or the rights granted
pursuant to Section 12.4(h) (Transfer of Regulatory Filings and Regulatory Approvals) and this Agreement has been terminated by Lian pursuant to Section 12.3(a) (Termination for Material Breach), then Landos will pay to Lian, in
consideration of the rights granted to Landos, [***]. 



  
 46 














	 	(d)	 Discontinuation of JSC. Upon termination of this Agreement in its entirety, the JSC will cease to exist;
provided, however, that if this Agreement is terminated with respect to one or more Terminated Products or Terminated Regions only, then the JSC will continue with respect to the non-terminated
Licensed Products or Regions only. 


  

	 	(e)	 Accrued Obligations. Expiration or termination of this Agreement for any reason will not release either
Party from any obligation or liability that, on the effective date of such expiration or termination, has already accrued to the other Party or that is attributable to a period prior to such expiration or termination. 



 

	 	(f)	 Survival. This Section 12.4(f) (Survival), the provisions set forth in the following Sections, as
well as, to the extent applicable, any other Sections or defined terms referred to in such Sections or Articles or necessary to give them effect, will survive any expiration or termination of this Agreement in its entirety: Articles 6 (solely to the

	 	(ii)	 Landos Buy-Back. Upon expiration of any Sell-Off Period in any Region, Landos will have the right to purchase all of Lian’s and its Affiliates’ remaining inventory of Licensed Products held as of the effective date of expiration of such Sell-Off Period at a price equal to (A) [***], if supplied by Landos or (B) if Manufactured by Lian, [***].

of this Agreement pursuant to Section 12.3 (Early Termination), after Landos’ written request, Lian will, to the extent permitted under applicable Laws, and at Landos’ sole cost and expense (unless the applicable termination giving

ARTICLE 13 
 DISPUTE
RESOLUTION 
  

	13.1	 Dispute Resolution; Escalation. The Parties recognize that disputes as to certain matters arising out of
or in connection with this Agreement may arise from time to time. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising out of or in connection with this Agreement in an expedited manner by
mutual cooperation. To accomplish this objective, any and all disputes between the Parties arising out of or in connection with this Agreement (other than matters within the purview of the JSC, which will be resolved in accordance with
Section 5.5 (Decision-Making; Escalation to Senior Officers)), will first be referred to the Senior Officers for resolution. The Senior Officers will attempt to resolve the matter in good faith. If the Senior Officers fail to resolve such
matter within [***] Business Days after the date on which the matter is referred to the Senior Officers (unless a longer period is agreed to by the Parties), then either Party may submit the dispute for final resolution by binding arbitration in
accordance with Section 13.2 (Arbitration). 


  

	13.2	 Arbitration. Except as set forth in Section 12.4(c) (License Grant to Landos) and this

Section 13.1 (Dispute Resolution; Escalation) will be referred to and finally resolved by arbitration in accordance with the International Chamber of Commerce (the “Rules”) by an arbitral tribunal composed of three arbitrators,
all of whom will have previous judicial experience and significant experience in the biopharmaceutical industry, with each Party appointing one arbitrator and the third arbitrator to be selected by agreement of the two arbitrators appointed by the
Parties. If the two initial arbitrators are unable to select a third arbitrator within [***] days, then the third arbitrator will be appointed in accordance with ICC rules. The foregoing arbitration proceedings may be commenced by either Party by
notice to the other Party. Unless otherwise agreed by the Parties, all such arbitration proceedings will be held in [***]. All arbitration proceedings will be conducted in the English language. The arbitrators will consider grants of equitable
relief and orders for specific performance as co-equal remedies along with awards of monetary damages. The arbitrators will have no authority to award punitive damages. The allocation of expenses of the
arbitration, including reasonable attorney’s fees, will be determined by the arbitrators, or, in the absence of such determination, each Party will pay its own expenses. The Parties hereby agree that the arbitrators have authority to issue
rulings and orders regarding all procedural and evidentiary matters that the arbitrators deem reasonable and necessary with or without petition therefore by the Parties as well as the final ruling and judgment. All rulings by the arbitrators will be
final. Notwithstanding any provision to the contrary set forth in this Agreement, any Party may seek equitable measures of protection in the form of attachment of assets or injunctive relief (including specific performance and injunctive relief) in
any matter relating to the proprietary rights and interests of either Party from any court of competent jurisdiction, pending a decision by the arbitral tribunal in accordance with this Section 13.2 (Arbitration). The Parties hereby exclude any
right of appeal to any court on the merits of such matter. The provisions of this Section 13.2 (Arbitration) may be enforced and judgment on the award (including equitable 



  
 48 














	 	
remedies) granted in any arbitration hereunder may be entered in any court having jurisdiction over the award or any of the Parties or any of their respective assets. Except to the extent
necessary to confirm an award or as may be required by Laws, neither a Party nor an arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of both Parties. The Parties agree that, in the event
of a dispute over the nature or quality of performance under this Agreement, neither Party may terminate this Agreement until final resolution of the dispute through arbitration or other judicial determination. Nothing in this Section 13.2
(Arbitration) will preclude either Party from seeking interim or provisional relief from a court of competent jurisdiction, including a temporary restraining order, preliminary injunction or other interim equitable relief, concerning a dispute
either prior to or during any arbitration if necessary to protect the interests of such Party or to preserve the status quo pending the arbitration proceeding. Notwithstanding the Parties’ agreement to arbitrate, unless the Parties agree in
writing in any particular case, claims and disputes between the Parties relating to or arising out of, or for which resolution depends in whole or in part on a determination of the interpretation, scope, validity, enforceability or infringement of,
Patent Rights or of any Trademark rights relating to any Licensed Products will not be subject to arbitration under this Agreement, and the Parties may pursue whatever rights and remedies may be available to them under law or equity, including
litigation in a court of competent jurisdiction, with respect to such claims and disputes. 

  

	13.3	 JURY WAIVER. EACH PARTY, TO THE EXTENT PERMITTED BY LAW, KNOWINGLY, VOLUNTARILY, AND INTENTIONALLY
WAIVES ITS RIGHT TO A TRIAL BY JURY IN ANY ACTION OR OTHER LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT AND THE TRANSACTIONS IT CONTEMPLATES TO ARBITRATE AS SET FORTH IN SECTION 13.2 (ARBITRATION). THIS WAIVER APPLIES TO ANY ACTION
OR LEGAL PROCEEDING, WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE. 


 ARTICLE 14 

MISCELLANEOUS 
  

	14.1	 Assignment. This Agreement and the rights and obligations of each Party under this Agreement will not be
assignable, delegable, transferable, pledged or otherwise disposed of by either Party without the prior written consent of the other Party; provided, however, that either Party may assign or transfer this Agreement together with all of
its rights and obligations hereunder, without such consent (but with written notice to the other Party), (A) to an Affiliate or (B) to a successor in interest in connection with the transfer or sale of all or substantially all of its business
or assets to which this Agreement relates, or in the event of its merger or consolidation, reorganization or similar transaction. Any permitted assignment of the rights and obligations of a Party under this Agreement will be binding on, and inure to
the benefit of and be enforceable by and against, the successors and permitted assigns of the assigning Party. Any assignment in violation of this Section 14.1 (Assignment) will be null and void. 



 

	14.2	 Choice of Laws. This Agreement will be governed by and interpreted under the Laws of the State of New
York, without regard to the conflicts of law principles thereof. Any dispute, controversy, claim or difference of any kind whatsoever arising out of or in connection with this Agreement will be resolved exclusively in accordance with
Section 13.2 (Arbitration); provided, however, that all questions concerning (a) inventorship of Patent Rights under this Agreement will be determined in accordance with Section 7.1 (Ownership of Inventions) and
(b) the construction or effect of Patent Rights will be determined in accordance with the Laws of the country, Region or other jurisdiction in which the particular patent within such Patent Rights has been filed or granted, as the case may be.
Any communication or proceedings resulting from disputes under this Agreement will be in English language. The Parties agree to exclude the application to this Agreement of the United Nations Conventions on Contracts for the International Sale of
Goods (1980).

	14.3	 Notices. All notices that are required or permitted hereunder will be in writing and sufficient if
delivered by internationally-recognized overnight courier or sent by registered or certified mail, postage prepaid, return receipt requested, and in each case, addressed as follows (with a courtesy copy sent by email, which will not constitute
notice):

writing in accordance herewith. Any such notice will be deemed to have been given: (a) on [***] after dispatch if sent by internationally-recognized overnight courier; or (b) on the [***] after dispatch if sent by registered or certified
mail, postage prepaid, return receipt requested. 
  

	14.4	 Severability. In the event that one or more provisions of this Agreement is held invalid, illegal or
unenforceable in any respect, then such provision will not render any other provision of this Agreement invalid or unenforceable, and all other provisions will remain in full force and effect and will be enforceable, unless the provisions that have
been found to be invalid or unenforceable will substantially affect the remaining rights or obligations granted or undertaken by either Party. The Parties agree to attempt to substitute for any invalid or unenforceable provision a provision which
achieves to the greatest extent possible the economic objectives of the invalid or unenforceable provision. 


  

	14.5	 Integration. This Agreement, together with all schedules attached hereto, constitutes the entire
agreement between the Parties with respect to the subject matter of this Agreement and supersedes all previous arrangements between the Parties with respect to the subject matter hereof, whether written or oral, including, effective as of the
Effective Date, the Term Sheet (provided that all information disclosed or exchanged under such agreement will be treated as Confidential Information hereunder). In the event of a conflict between the Development Plan or any schedules or
attachments to this Agreement, on the one hand, and this Agreement, on the other hand, the terms of this Agreement will govern. Each Party confirms that it is not relying on any representations or warranties of the other Party except as specifically
set forth in this Agreement. 



  
 50 














	14.6	 Waivers and Amendments. The failure of any Party to assert a right under this Agreement or to insist
upon compliance with any term or condition of this Agreement will not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition by the other Party. The exercise by any Party of any right or
election under the terms or covenants herein will not preclude or prejudice any Party from exercising the same or any other right it may have under this Agreement, irrespective of any previous action or proceeding taken by the Parties hereunder.
Notwithstanding the authority granted to the JSC under this Agreement, (a) no waiver will be effective unless it has been given in writing and signed by the Party giving such waiver, and (b) no provision of this Agreement may be amended or
modified other than by a written document signed by authorized representatives of each Party. 


  

	14.7	 Independent Contractors; No Agency. Neither Party will have any responsibility for the hiring, firing or
compensation of the other Party’s or such other Party’s Affiliates’ employees or for any employee benefits with respect thereto. No employee or representative of a Party or its Affiliates will have any authority to bind or obligate
the other Party for any sum or in any manner whatsoever, or to create or impose any contractual or other liability on such other Party, without such other Party’s written approval. For all purposes, and notwithstanding any other provision to
the contrary set forth in this Agreement, each Party’s legal relationship under this Agreement to the other Party will be that of independent contractor, and the relationship between the two Parties will not constitute a partnership, joint
venture, or agency, including for all tax purposes, except as otherwise required by applicable Law. 


  

	14.8	 Affiliates, Sublicensees, and Contractors. To the extent that this Agreement imposes
obligations on Affiliates, Sublicensees, or contractors of a Party, such Party will cause its Affiliates and its Sublicensees and contractors to perform such obligations, as applicable. Either Party may use one or more of its Affiliates,
Sublicensees, or contractors to perform its obligations and duties or exercise its rights under this Agreement, solely to the extent permitted and as specified in this Agreement; provided that (a) each such Affiliate, Sublicensee, or
contractor will perform any such obligations delegated to it in compliance with the applicable terms and conditions of this Agreement as if such Affiliate, Sublicensee, or contractor were a party hereto, (b) the performance of any obligations
of a Party’s by its Affiliates, Sublicensees, or contractors will not diminish, reduce, or eliminate any obligation of such Party under this Agreement, and (c) subject to such Party’s assignment to an Affiliate pursuant to
Section 14.1 (Assignment), such Party will remain liable under this Agreement for the prompt payment and performance of all of its obligations under this Agreement. Subject to this Section 14.8 (Affiliates, Sublicensees, and Contractors),
if a Party exercises its rights and performs its obligations under this Agreement through one or more of its Affiliates, “Landos” will be interpreted to mean “Landos or its Affiliates” and “Lian” will be interpreted to
mean “Lian or its Affiliates” where necessary to give each Party’s Affiliates the benefit of the rights provided to such Party in this Agreement and the ability to perform its obligations under this Agreement. 



 

	14.9	 Force Majeure. Neither Party will be held liable to the other Party nor be deemed to have defaulted
under or breached this Agreement for failure or delay in achieving any objective, satisfying any condition, or performing any obligation under this Agreement to the extent that such failure or delay is caused by or results from acts or events beyond
the reasonable control of such Party, including, without limitation, acts of God, embargoes, war, acts of war (whether war be declared or not), terrorism, insurrections, riots, civil commotions, strikes, lockouts, or other labor disturbances,
government actions, unavailability of supplies, materials or transportation, fire, earthquakes, floods, epidemics, pandemics, the spread of infectious diseases, and quarantines (“Force Majeure”). The Parties agree the effects of the
COVID-19 pandemic that is ongoing as of the Effective Date (including related government orders) may be invoked as a Force Majeure for the purposes of this Agreement even though the pandemic




  
 51 














	 	
is ongoing and those effects may be reasonably foreseeable as of the Effective Date. In addition, a Force Majeure may include reasonable measures affirmatively taken by a Party or its Affiliates
to respond to any epidemic, pandemic, or spread of infectious disease (including the COVID-19 pandemic), or other Force Majeure event, such as requiring employees to stay home, closures of facilities, delays
of Clinical Trials, or cessation of activities in response to an epidemic or other Force Majeure event. Notwithstanding the foregoing, a Party will not be excused from making payments owed hereunder due to any such Force Majeure circumstances
affecting such Party. The affected Party will notify the other Party in writing of any Force Majeure circumstances as soon as reasonably practical, and will provide a good faith estimate of the period for which its failure or delay in performance
under the Agreement is expected to continue based on currently available information. The affected Party shall promptly undertake all reasonable efforts necessary to cure such Force Majeure circumstances. 


 

	14.10	 No Third Party Beneficiary Rights. The representations, warranties, covenants and agreements set forth
in this Agreement are for the sole benefit of the Parties and their successors and permitted assigns, and they will not be construed as conferring any rights on any other Third Party. This Agreement is not intended to and will not be construed to
give any Third Party any interest or rights (including any Third Party beneficiary rights) with respect to or in connection with any agreement or provision contained herein or contemplated hereby, other than, to the extent provided in Article 10
(Indemnification; Damages), the Indemnified Parties. 


  

	14.11	 Non-exclusive Remedy. Except as expressly provided
herein, the rights and remedies provided herein are cumulative and each Party retains all remedies at law or in equity, including the Parties’ ability to receive legal damages or equitable relief, with respect to any breach of this Agreement.

day or Business Day, or the day or Business Day of an act or event, it is to be calculated exclusive of that day or Business Day; (i) “monthly” means on a calendar month basis, (j) “quarter” or “quarterly” means on a
Calendar Quarter basis; (k) “annual” or “annually” means on a Calendar Year basis; (l) “year” means a 365-day period unless Calendar Year is specified; (m) references to a
particular Person include such Person’s successors and assigns to the extent not prohibited by this Agreement; (n) the use of any gender herein will be deemed to encompass references to either or both genders, and the use of the singular

other Party under this Agreement, except to the extent expressly otherwise provided; (s) provisions that require that a Party, or the JSC hereunder “agree”, “consent” or “approve” or the like will be deemed to
require that such agreement, consent or approval be specific and in writing in a written agreement, letter or approved minutes, but, except as expressly provided herein, excluding e-mail and instant messaging;
and (t) the word “will” will be construed to have the same meaning and effect as the word “shall.” 

  

	14.13	 Further Assurances. Each Party will duly execute and deliver, or cause to be duly executed and
delivered, such further instruments and do and cause to be done such further acts and things, including the filing of such assignments, agreements, documents, and instruments, as may be necessary or as the other Party may reasonably request in
connection with this Agreement or to carry out more effectively the provisions and purposes hereof, or to better assure and confirm unto such other Party its rights and remedies under this Agreement (including working collaboratively to correct and
clerical, typographical, or other similar errors in this Agreement). 


  

	14.14	 Ambiguities; No Presumption. Each of the Parties acknowledges and agrees that this Agreement has been
diligently reviewed by and negotiated by and between them, that in such negotiations each of them has been represented by competent counsel and that the final agreement contained herein, including the language whereby it has been expressed,
represents the joint efforts of the Parties hereto and their counsel. Accordingly, in interpreting this Agreement or any provision hereof, no presumption will apply against any Party as being responsible for the wording or drafting of this Agreement

governmental approval, except in compliance with U.S. export Laws and regulations. 


  

	14.16	 Execution in Counterparts; Electronic Signatures. This Agreement may be executed in counterparts, each
of which counterparts, when so executed and delivered, will be deemed to be an original, and all of which counterparts, taken together, will constitute one and the same instrument even if both Parties have not executed the same counterpart.
