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

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).

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

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.

	 	(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

	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

“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.
