	13.1	 Infringement by a Third Party 



 

	 	(A)	 In the event of Ascendis or the Licensee becoming aware of any suspected infringement or any unauthorised use
by a Third Party of any of the Ascendis Patents, Ascendis Technical Information, Ascendis Program IP, Licensee Program IP, and/or the Joint Program IP in the Field in the Territory, the Party becoming aware of the same shall promptly notify the
other Party. 


  

	 	(B)	 Where such suspected infringement or unauthorised use is of the Ascendis Patents or Ascendis Technical
Information (including those within the Joint Program IP and/or Ascendis Program IP), in each case (i) outside the Territory, or (ii) inside the Territory but outside the Field, Ascendis shall, at its own expense, have the exclusive
right, but not the obligation, to take or threaten any legal action that it deems appropriate to halt such suspected infringement and to retain any amounts recovered in respect of such suspected infringement or unauthorised use. Termination and/or
settlement of the litigation are at the sole discretion of Ascendis (i.e., without the prior consent of the Licensee), provided such termination or settlement does not impose a liability (monetary or otherwise) on Licensee or limit the rights of
Licensee under this Agreement, or otherwise materially impair Licensee’s rights in the relevant Ascendis Patent in each case without Licensee’s prior written consent. 



 

	 	(C)	 Where such suspected infringement or unauthorised use is of the Ascendis Patents Ascendis Technical Information
(including those within the Joint Program IP and/or any Ascendis Program IP), in each case in the Field in the Territory, the Licensee shall, at its own expense, have the first right, but not the obligation to take or threaten any legal action that
it deems appropriate to halt such suspected infringement (provided that [***]). Each Party shall retain the following percent of any remaining amounts recovered in respect of such suspected infringement or unauthorised use after the Licensee has
recouped its expenses: the Licensee shall retain [***] percent ([***]%) and Ascendis shall retain [***] percent ([***]%). Termination and/or settlement of the litigation are at the sole discretion of the Licensee (i.e., without the prior consent of
Ascendis), provided such termination or settlement does not impose a liability (monetary or otherwise) on Ascendis or limit the rights of Ascendis under this Agreement, or otherwise materially impair Ascendis’s rights in the relevant Ascendis
Patent in each case without Ascendis’s prior written consent. 


  

	 	(D)	 If Ascendis wishes to take or threaten legal action and the Licensee has the first right to do so under Clause
13.1(C), but does not do so within [***] ([***]) days of becoming aware of potential infringement, then Ascendis may take or threaten such legal action and the Licensee shall, at Ascendis’ request, lend its name where necessary or desirable to
proceedings relating to such action and provide reasonable assistance in such proceedings. In such circumstances, Ascendis shall control the conduct of the action but shall consult the Licensee in good faith with regard to significant decisions.
Each Party shall retain the following percent of any remaining amounts recovered in respect of such suspected infringement or unauthorised use after Ascendis has recouped its expenses: Ascendis shall retain an amount equal to [***] percent ([***]%)
and the Licensee shall retain the remaining [***] percent ([***]%). Termination and/or settlement of the litigation are at the sole discretion of Ascendis (i.e., without the prior consent of the Licensee). 



  
 20 














	 	(E)	 Each Party shall provide to the Party enforcing any such rights under this Clause 13.1 reasonable assistance in
such enforcement, at such enforcing Party’s request and expense, including joining such action as a party plaintiff if required by Applicable Laws to pursue such action. The enforcing Party shall keep the other Party regularly informed of the
status and progress of such enforcement efforts and shall reasonably consider the other Party’s comments on any important aspects of such enforcement, including determination of litigation strategy and filing of important papers to the
competent court. 


  

	13.2	 Defence of Third Party Claims 



 

	 	(A)	 In the event that the development or commercialisation of a Licensed Product results in action by a Third Party
against a Party (or its Affiliates or Sub-Licensees) for infringement or unauthorised use of Intellectual Property or confidential information anywhere in the Territory, such Party shall promptly notify the
other Party in writing. 


  

	 	(B)	 Each Party (or its Affiliates or Sub-Licensees) against whom such
action is brought shall: (i) have the right but not the obligation to defend such action; (ii) have the right to be represented by separate legal advisors; (iii) keep the other Party informed of, and assist and co-operate with the other Party in, any such action; and (iv) bear its own costs. 


  

	14.	 Warranties 



 

	14.1	 Each Party warrants to the other Party that it: 



 

	 	(A)	 is free to enter into this Agreement and to carry out its obligations hereunder without violating any
obligation owed by it or any of its Affiliates to any Third Party; 


  

	 	(B)	 shall not, during the existence of this Agreement, enter into any assignments, licences, obligations, charges
or assignments, either written, oral or implied, which are or shall be inconsistent with this Agreement; 


  

	 	(C)	 has obtained all necessary corporate approvals to enter into and execute this Agreement; 



 

	 	(D)	 has never been debarred, disqualified or banned from practising medicine and that it is not under investigation
by any Regulatory Authority for debarment, disqualification or any similar regulatory action in any country. 


  

	14.2	 Ascendis represents and warrants to the Licensee that, as of the Effective Date, Ascendis:



  

	 	(A)	 Controls the Ascendis Patents and Ascendis Technical Information in the Field in the Territory;



  

	 	(B)	 has the right to grant to the Licensee the rights and licences granted to the Licensee under the terms and
conditions of this Agreement, 


  

	 	(C)	 has the right to provide and disclose to the Licensee the Ascendis Technical Information that it provides or
discloses to the Licensee under the terms and conditions of this Agreement; 


  

	 	(D)	 itself and its employees have not received notice of any actions, lawsuits, claims or arbitration or material
adverse proceedings (other than on-going routine patent prosecution matters) in any way relating to the Ascendis Patents, Ascendis Technical Information or Ascendis Platform Technology; and




  
 21 














	 	(E)	 is not, to [***] its knowledge, aware that the use of Licensed Product Patents in Schedule 1, the Ascendis
Patents existing as of the Effective Date, and/or Ascendis Technical Information listed in Schedule 2, for development or commercialisation of a Licensed Product infringes any Third Party’s Patent. 



 

	 	(F)	 there are no patents, patent applications or Technical Information that are owned or in-licensed by Ascendis and/or its Affiliates that Ascendis and/or its Affiliates do not Control and are not included in the license granted to Licensee under this Agreement, which would be infringed by or would
otherwise cover the development, manufacture and/or commercialization of the Licensed Product in the Field in the Territory. During the Term, Ascendis and/or its Affiliates shall maintain the Control of patents, patent applications and/or Technical
Information that are then-owned or then-in-licensed by Ascendis and/or its Affiliates that would be infringed by or would otherwise cover the development, manufacture
and/or commercialization of the Licensed Product in the Field in the Territory (including by reserving such rights from any Third Party carrying out the development, manufacture and/or commercialization of the Licensed Product on behalf of or under
a license from Ascendis or its Affiliates) so that such patents, patent applications and/or Technical Information are included in the license granted to Licensee hereunder; provided, that for clarity this provision shall not be deemed to impose any
obligation on Ascendis to obtain ownership or license rights to any patents, patent applications, Technical Information, or intellectual property rights of any Third Party. 



 

	14.3	 EXCEPT AS OTHERWISE EXPRESSLY STATED IN THIS AGREEMENT, NEITHER PARTY MAKES ANY REPRESENTATION OR WARRANTY OF
ANY KIND WITH RESPECT TO INTELLECTUAL PROPERTY RIGHTS OR CONFIDENTIAL INFORMATION SUPPLIED BY IT TO THE OTHER PARTY HEREUNDER, AND EXPRESSLY DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. 


  

	15.	 Indemnification 



 

	15.1	 Except as provided in Clause 15.2 below, the Licensee shall indemnify, defend and hold harmless Ascendis and
its Affiliates, and their respective directors, officers, employees and agents (each an “Ascendis Indemnitee”) from and against all Losses arising out of or resulting from any Third Party Claims to the extent such Losses
result from or arise out of: (a) the activities performed by the Licensee in connection with the exercise of its rights or obligations under this Agreement (including the exploitation of the Licensed Product(s) in the Territory); (b) breach by
the Licensee of the representations and warranties provided in Clause 14; (c) gross negligence, recklessness or wilful misconduct by the Licensee; or (d) violation of Applicable Law by the Licensee. The indemnification obligations set forth in
this Clause 15.1 shall not apply to the extent that any such Losses arising from such Third Party Claim arose or resulted from the events specified in Clause 15.2(a)-(d). 



 

	15.2	 Except as provided in Clause 15.1 above, Ascendis shall indemnify, defend and hold harmless the Licensee, its
Affiliates, and their respective directors, officers, employees and agents (each a “Licensee Indemnitee”) from and against all Losses arising out of or resulting from any Third Party Claims to the extent such Losses result from or
arise out of: (a) the activities performed by Ascendis, its Affiliates, and Sublicensees in connection with the exercise of its rights or obligations under this Agreement, including the exploitation of the




  
 22 














	 	
Licensed Product(s) outside of the Territory; (b) breach by Ascendis of the representations and warranties provided in Clause 14; (c) gross negligence, recklessness or wilful misconduct by
Ascendis, its Affiliates, and Sublicensees; or (d) violation of Applicable Law by Ascendis, its Affiliates, and Sublicensees. The indemnification obligations set forth in this Clause 15.2 shall not apply to the extent that any such Third Party
Claim arose or resulted from the events specified in Clause 15.1(a)-(d). 

  

	15.3	 In the event that an Ascendis Indemnitee or a Licensee Indemnitee, as applicable (hereinafter an
“Indemnified Party”) seeks indemnification under this Clause 15, such Indemnified Party shall: (i) give prompt notice to the indemnifying Party of any such Third Party Claim; (ii) permit the indemnifying Party to assume
direction and control of the defence of such Third Party Claim (including decisions regarding its settlement or other disposition, which may be made in the indemnifying Party’s sole discretion except as otherwise provided herein); (iii) assist
the indemnifying Party at the indemnifying Party’s expense in defending such Third Party Claim; and (iv) not compromise or settle such Third Party Claim without the indemnifying Party’s prior written consent, which shall not be
unreasonably withheld or delayed. The failure to deliver written notice to the indemnifying Party within a reasonable time after the commencement of any such Third Party Claim, to the extent prejudicial to its ability to defend such Third Party
Claim, shall relieve the indemnifying Party of any obligation to the Indemnified Party under this Clause 15. The Indemnified Party may participate in the defence of such Third Party Claim through counsel of its choice, but the reasonable cost of
such counsel shall be borne solely by the Indemnified Party. It is understood that only Ascendis or the Licensee may claim indemnity under this Clause 15 (on its own behalf or on behalf of its Indemnified Parties), and other Indemnified Parties may
not directly claim indemnity hereunder. No compromise or settlement of any Third Party Claim may be effected by the indemnifying Party without the Indemnified Party’s prior written consent (which consent shall not be unreasonably withheld or
delayed), unless: (a) there is no finding or admission of any violation of law or any violation of the rights of any person and no effect on any other claims that may be made against the Indemnified Party; (b) the sole relief provided is
monetary damages that are paid in full by the indemnifying Party; and (c) the Indemnified Party’s rights under this Agreement are not adversely affected. The Indemnified Party shall have no right to settle any such Third Party Claim
without the prior written consent of the indemnifying Party (and any such settlement without the prior written consent of the indemnifying Party shall relieve the indemnifying Party of its obligations under this Clause 15), unless: (x) there is
no finding or admission of any violation of law or any violation of the rights of any person and no effect on any other claims that may be made against the Indemnifying Party; (y) the sole relief provided is monetary damages that are paid in
full by the Indemnified Party; and (z) the indemnifying Party’s rights under this Agreement are not adversely affected. 


  

	16.	 Limitation of Liability 



 

	16.1	 Subject to Clause 16.2, neither of the Parties nor any of their Affiliates shall be liable to each other under
any contract, negligence, strict liability or other legal or equitable theory for indirect, incidental, special, punitive, exemplary or consequential damages arising out of or resulting from this Agreement. The foregoing shall not limit:



  

	 	(A)	 the obligations of either Party from and against Third Party claims under Clauses 15.1 or 15.2 to the extent

the nature of the dispute. Each Party shall select one (1) arbitrator, and the two (2) arbitrators so selected shall choose a third arbitrator. All three (3) arbitrators shall serve as neutrals and have at least [***] ([***]) years
of: (a) dispute resolution experience (including judicial experience); and/or (b) legal or business experience in the biotech or pharmaceutical industry. In any event, at least one (1) arbitrator shall satisfy the foregoing experience

award on each issue that clearly states the basis upon which such resolution and award is made. The written resolution and award shall be delivered to the Parties as expeditiously as possible, but in no event more than [***] ([***]) days after

the powers of the arbitrators. At the request of either Party, the arbitrators shall enter an appropriate protective order to maintain the confidentiality of information produced or exchanged in the course of the arbitration proceedings. The
arbitrators shall have the power to decide all questions of arbitrability. The Parties agree that: (i) they shall share equally the fees and expenses of the arbitrators; and (ii) each Party shall bear its own attorneys’ fees and
associated costs and expenses. 
  

	20.3	 Patent validity 



Notwithstanding the other provisions of this Clause 20, any dispute that involves the validity, infringement or claim interpretation of a
Patent that is issued: (a) in the United States shall be subject to actions before the United States Patent and Trademark Office and/or submitted exclusively to the federal court located in the jurisdiction of the district where any


  
 28 













 
of the defendants resides; and (b) in any other country shall be brought before an appropriate regulatory or administrative body or court in that country, and the Parties hereby consent to
the jurisdiction and venue of such courts and bodies. For the sake of clarity, such Patent disputes shall not be subject to the provisions of Clause 20.2. Nothing in this Agreement shall be construed to prevent the Licensee from disputing or
challenging the validity of a Third Party’s Patent. 
  

	21.	 Miscellaneous 



 

	21.1	 General assurances 



At any time after the date hereof each of the Parties shall, at the request and cost of the other Party, execute or procure the execution of
such documents and perform or procure the performance of such acts as the other Party may reasonably require for the purpose of giving to the other Party the full benefit of all the provisions of this Agreement, subject to any express restrictions
in this Agreement on the extent of either Party’s obligations under this Agreement. This includes in particular (without prejudice to the generality of the foregoing) entry into forms of licence or other instruments confirming such rights for
registration with appropriate Intellectual Property Offices (including in the form set out in Schedule 4), Regulatory Authorities and other authorities in the Territory. 
  

	21.2	 Unenforceability and severability 



If any of the provisions of this Agreement are held to be void or unenforceable, then such void or unenforceable provisions shall be replaced
by valid and enforceable provisions that will achieve as far as possible the economic business intentions of the Parties. However, the remainder of this Agreement will remain in full force and effect, provided that the material interests of the
Parties are not affected, i.e. the Parties would presumably have concluded this Agreement without the unenforceable provisions. 
  

	21.3	 Assignments 



Neither this Agreement nor any of the rights and obligations created herein is assignable or transferable by either Party without the prior
written consent of the other, such consent not to be unreasonably withheld or delayed. 
 Notwithstanding the preceding sentence, each Party
is entitled to assign this Agreement and any rights created herein to, subject to the assumption of the obligations herein by, any Affiliate of such Party or any purchaser of the whole or a substantial part of the business of such Party. For the
avoidance of doubt, the Parties agree that the Ascendis Platform Technology constitutes a substantial part of the business of Ascendis. 
  

	21.4	 Rights cumulative and other matters 



 

	 	(A)	 The rights, powers, privileges and remedies provided in this Agreement are cumulative and are not exclusive of
any rights, powers, privileges or remedies provided by law or otherwise. 


  

	 	(B)	 No failure to exercise nor any delay in exercising by any Party to this Agreement of any right, power,
