pursuant to 8.4 below. 
 8.3 In the event that a claim or suit is asserted or brought against the Company alleging that
the manufacture or sale of any Licensed Product or Licensed Process by the Company, an Affiliate, or Company Sublicensee, or the use of such Licensed Product or Licensed Process by any customer of any of the foregoing, infringes proprietary rights
of a third party, the Company shall give written notice thereof to Ovamed. The Company may, in its sole discretion, modify such Licensed Product or such Licensed Process to avoid such infringement and/or may settle on terms that it deems advisable
in its sole discretion, subject to paragraph 8.2. Otherwise, the Company shall have the right, but not the obligation, to defend any such claim or suit. In the event the Company elects not to defend such suit, Ovamed shall have the right, but not
the obligation to do so at its sole expense. 
 8.4 Any recovery of damages by the Company, in any such suit under
Article 8.2 and 8.3, shall be applied first in satisfaction of any unreimbursed expenses and legal fees of the Company relating to the suit. The balance remaining from such suit shall be allocated accordingly: (a) amounts relating to lost sales
shall be allocated in their entirety to the Company, provided however, that Company shall pay Ovamed royalties due for such lost sales pursuant to Article 4 of this Agreement; and (b) any amounts remaining after the allocation of amounts

litigation costs incurred by the Company in any country in the Territory pursuant to this Article 8 including all amounts paid in judgment or settlement of litigation within the scope of this Article 8 against royalties or other fees thereafter
payable to Ovamed hereunder for such country. If the costs of such litigation in such country exceeds the royalties payable to Ovamed in any year in which such costs are incurred then the amount of such costs, expenses and amounts paid in judgment
or settlement, in excess of the royalties payable shall be carried over and credited against royalty payments in future years for such country. 
 8.6 If within [*******] after receiving notice of any alleged infringement of the Patent Rights, the Company shall have been unsuccessful in persuading the alleged infringer to desist, or shall not
have brought and shall not be diligently prosecuting an infringement action, or 

  
 11.

but not the obligation, to prosecute, at its own expense and utilizing counsel of its choice, any infringement of the Patent Rights, and the Company may, for such purposes, join Ovamed and/or IMF as a party plaintiff. The total cost of any such
infringement action commenced solely by Ovamed shall be borne by Ovamed and Ovamed shall keep any recovery or damages for infringement or otherwise derived therefrom and such shall not be applicable to any royalty obligation of the Company.

 8.7 In any suit to enforce and/or defend the Patent Rights pursuant to this Agreement, the party not in control of
such suit shall, at the request and expense of the controlling patty, cooperate in all respects and, to the extent possible, have its employees testify when requested and make available relevant records, papers, information, samples, specimens, and
the like. 
 8.8 If the Company, its Affiliate or Company Sublicensee elects to commence an action as described above,
the Company may reduce, by up to [*******] percent ([*******]%), the royalty due to Ovamed earned under the patent subject to suit by [*******] percent ([*******]%) of the amount of the expenses and costs of such action, including attorney fees. In
the event that such [*******] percent ([*******]%) of such expenses and costs exceed the amount of royalties withheld by the Company for any calendar year, the Company may to that extent reduce the royalties due to Ovamed from the Company in
succeeding calendar years, but never by more than [*******] percent ([*******]%) of the royalty due in any one year. 

ARTICLE 9 – TERMINATION OF AGREEMENT 
 9.1 Upon any termination of this Agreement, and except as provided herein to the contrary, all rights and obligations of the Parties hereunder shall cease, except as follows: 

 

	(a)	Ovamed’s right to receive or recover and the Company’s obligation to pay royalties accrued or accruable for payment at the time of any termination;


  

	(b)	Ovamed’s obligation to maintain records and the Company’s right to conduct a final audit as provided in Article 5 of this Agreement; and


  

	(c)	Any cause of action or claim of by either party, accrued or to accrue because of any breach or default by the Company. 


9.2 In the event the Company fails to make payments due hereunder which is not subject to a bona fide good faith dispute, Ovamed
shall provide the Company with [*******] written notice of such failure. The Company shall then have [*******] from the date of such written notice in which to make the payment due. If payments are not so made within the time limit, Ovamed may
immediately terminate this Agreement by written notice. 
 9.3 In the event that the Company shall be in default in the
performance of any material obligations under this Agreement (other than as provided in 9.2 above which shall take precedence over any other default), and if the default has not been remedied within [*******] after the date of notice in writing of
such default, Ovamed may terminate this Agreement immediately by written notice. 

  
 12.









 9.4 If the Company shall become bankrupt, or shall file a petition in bankruptcy and
such petition is not dismissed within [*******] after it has been filed, or if the business of the Company shall be placed in the hands of a receiver, assignee or trustee for the benefit of creditors, whether by the voluntary act of the Company or
otherwise, this Agreement shall automatically terminate. 
 9.5 In the event that this Agreement is terminated due to the
Company’s breach, Company Sublicensee shall have at least [*******] in which to bring this Agreement back into good standing. Should the nature of the activity associated with bringing this Agreement back into good standing reasonably require
more than [*******], then Ovamed shall grant Company Sublicensee additional time in which to bring this Agreement back into good standing. 
 9.6 The Company shall have the right to terminate this Agreement by giving [*******] advance written notice to Ovamed to that effect. Upon termination, a final report shall be submitted and any
royalty payments and unreimbursed patent expenses due to Ovamed become immediately payable. 
 9.7 The Company shall have
the right during a period of six (6) months following the effective date of such termination to sell or otherwise dispose of the Licensed Product existing at the time of such termination, and shall make a final report and payment of all
royalties related thereto within sixty (60) days following the end of such period or the date of the final disposition of such inventory, whichever first occurs, 
 9.8 Upon termination of this Agreement for any reason, nothing herein shall be construed to release either party from any obligation that matured prior to the effective date of such termination or
obligations under Articles 4, 5, 12 and 16, for the exception of obligations under Articles 4.1.1 and 4.1.2. Ovamed hereby acknowledges and agrees that, should the Company terminate this Agreement within [*******] after The pre-IND Meeting, then the
Company shall have no obligation to pay any amounts pursuant to Articles 4.1.1 and 4.1.2. The Company and/or any Company Sublicensee thereof may, however, after the effective date of such termination and continuing for a period not to exceed
[*******] thereafter, sell all completed Licensed Products, and any Licensed Products in the process of manufacture at the time of such termination, and sell the same, provided that the Company shall pay or cause to be paid to Ovamed the royalties
thereon as required by Article 4 of this Agreement and shall submit the reports required by Article 5 hereof on the sales of Licensed Products. 
 9.9 If not terminated sooner, this Agreement shall terminate on the date of the last to expire valid claim contained in the Patent Rights in accordance with Section 2.1. 

9.10 Force Majeure: Neither party is responsible for delays resulting from causes beyond its reasonable control, including without
limitation fire, explosion, flood, war, strike, or riot, provided that the non-performing party uses commercially reasonable efforts to avoid or remove those causes of nonperformance and continues performance under this Agreement with reasonable
dispatch whenever the causes are removed.
