Agreement and/or the written memorialization of transactions contemplated hereunder, such as pertaining to the Development of the Compounds and Products, to constitute a qualifying written Joint Research Agreement.

10.5 Patent Term Extensions in the Licensed Territory. On a country-by-country and Product-by-Product basis, Astellas shall have the right, at its sole discretion, to apply for patent term extension in the Licensed Territory for any Patent Covering the manufacture, use or sale of such Product in such country, and will act with reasonable promptness in light of the development stage of Products to apply for any such patent term extension. Astellas shall keep Aquinox apprised of its plans regarding any such patent term extensions through the JSC and the Joint Clinical Development Plan. Aquinox shall cooperate reasonably with Astellas in making such filings or actions, for example and without limitation, making available all required regulatory Data and information and executing any required authorizations to apply for such patent term extension. All expenses incurred in connection with activities of each Party with respect to the Patent(s) for which Astellas seeks patent term extensions pursuant to this Section 10.5.1 shall be borne by Astellas. If Astellas receives patent term extension for an Astellas Patent or solely-owned Astellas Collaboration Patent instead of an Aquinox Patent, then, for purposes of Section 9.4.4(b), the last to expire Valid Claim will not be deemed to have expired until such date as it would have expired had the Aquinox Patent containing such Valid Claim received such patent term extension, provided that the foregoing shall not apply if Astellas can reasonably demonstrate that such Valid Claim would not have provided material exclusivity for the applicable Product in the applicable country if extended.

10.6 Infringement of Patents by Third Parties.

10.6.1 Notification. Each Party shall promptly notify the other Party in writing of any existing or threatened infringement of the Aquinox Patents, Astellas Patents, Astellas Collaboration Patents, or Joint Patents, in the Territory of which it becomes aware, and shall provide all evidence in such Party’s possession demonstrating such infringement.

10.6.2 Notice of Infringement.

The Party bringing the action shall have final decision-making authority with respect to such action, subject to Section 10.6.4.

10.6.3.4 Each Party shall bear all of its own internal costs incurred in connection with its activities under this Section 10.6.3, subject to reimbursement as set forth in Section 10.6.3.6.

10.6.3.5 The Party not bringing an action with respect to Product Infringement under this Section 10.6.3 shall be entitled to separate representation in such matter by counsel of its own choice and at its own expense, but such Party shall at all times cooperate fully with the Party bringing such action.

10.6.3.6 Any recovery shall be allocated first pro rata to the reimbursement of any expenses incurred by the Parties in such litigation (including reasonable expenses of outside counsel), and then (a) if Astellas was the Party bringing the suit, Astellas shall retain any remaining recovery, which, solely with respect to Product Infringement of an Aquinox Patent or Joint Patent shall be treated as Net Sales [***] for purposes of Sections 9.3.2 and 9.4, respectively, and (b) if Aquinox was the Party bringing the suit, Aquinox shall retain any remaining recovery.

10.7 Infringement of Third Party Rights.

10.7.1 Notice; Astellas First Right in the Licensed Territory. If either Party becomes aware that the manufacture, sale, or use of a Product in the Territory results in, or may result in, any claim, suit, or proceeding by a Third Party alleging patent infringement by either Party (or its Affiliates or (sub)licensees), such Party will promptly notify the other Party thereof in writing. Subject to Section 10.7.2, Astellas will have the first right, but not the obligation, to defend and control the defense of any such claim, suit or proceeding in the Licensed Territory at its own expense, using counsel of its own choice. Aquinox may participate in any such claim, suit or proceeding with counsel of its choice at its own expense. If Astellas elects (in a written communication submitted to Aquinox within a reasonable amount of time after notice of the alleged patent infringement) not to defend or control the defense of, or otherwise fails to initiate and maintain the defense of, any such claim, suit or proceeding, within such time period so that Aquinox is not prejudiced by any delays, Aquinox may conduct and control the defense of any such claim, suit or proceeding at its own expense. Each Party will keep the other Party reasonably informed of all material developments in connection with any such claim, suit, or proceeding. Each Party agrees to provide the other Party with copies of all pleadings filed in such action and to allow the other Party reasonable opportunity to participate in the defense of the claims. If Astellas is controlling the defense of any such claim, suit or proceeding, Astellas agrees to provide at Aquinox’s expense English translations, or summaries thereof, of all pleadings, discovery-requests, and key documents filed with the court reasonably promptly.

10.7.2 Possible Claims in the Other Party’s Territory.

10.7.2.1 Regardless of whether Aquinox elects to participate as a party in the claim, suit or proceeding, Astellas further agrees that, in the event the claim, suit or preceding under Section 10.7.1 is brought by a Third Party that is pursuing or has threatened in writing to the knowledge of Astellas to pursue similar claims outside the Licensed Territory against Aquinox, its Affiliates, agents or marketing or development partners and such claim is related to any Product, including any form or formulation thereof, Astellas shall: (a) provide to Aquinox at Aquinox’s expense English translation drafts of all official papers or other statements (whether written or oral) prior to their submission to the court in the lawsuit, in sufficient time to allow Aquinox to review, consider and substantively comment thereon; (b) reasonably consider taking action to incorporate Aquinox’s comments on all such official papers and statements, (c) not take positions in its defense that are inconsistent or at odds with positions that Aquinox is taking in defense, or anticipated defense, of related claims outside the Licensed Territory, to the extent such positions have been communicated to Astellas; (d) allow Aquinox the opportunity to participate in preparation of witnesses or other participants in the claim, suit or proceeding; (e) not settle any such claim, suit or proceeding without Aquinox’s prior consent, which consent shall not be unreasonably withheld or delayed, and (f) enter into a reasonable and customary joint defense agreement with Aquinox, upon Aquinox’s request.

10.7.2.2 Regardless of whether Astellas elects to participate as a party in the claim, suit or proceeding, Aquinox further agrees that, in the event the claim, suit or preceding under Section 10.7.1 is brought by a Third Party that is pursuing or has threatened in writing to the knowledge of Aquinox to pursue similar claims outside the Retained Territory against Astellas, its Affiliates, agents or marketing or development partners and such claim is related to any Product, including any form or formulation thereof, Aquinox shall: (a) provide to Astellas at Astellas’ expense English translation drafts of all official papers or other statements (whether written or oral) prior to their submission to the court in the lawsuit, in sufficient time to allow Astellas to review, consider and substantively comment thereon; (b) reasonably consider taking action to incorporate Astellas’ comments on all such official papers and statements, (c) discuss in good faith with Astellas any proposed position that Aquinox wishes to take in its defense that is inconsistent or at odds with positions that Astellas is taking in defense, or anticipated defense, of related claims outside the Retained Territory, to the extent such positions have been communicated to Aquinox; (d) allow Astellas the opportunity to participate in preparation of witnesses or other participants in the claim, suit or proceeding; and (e) enter into a reasonable and customary joint defense agreement with Astellas, upon Astellas’ request.

10.8 Patent Marking. Astellas shall not be required to mark such Products unless such markings or such notices would materially impact recoveries of damages or equitable remedies available under Applicable Law with respect to infringements of patents in the Licensed Territory.

10.9 Patent Oppositions and Other Proceedings.

10.9.1 Challenges to Third-Party Patent Rights. If either Party desires to bring an opposition, action for declaratory judgment, nullity action, invalidation action, interference, declaration for non-infringement, reexamination, or other attack upon the validity, title, or enforceability of a Patent owned or controlled by a Third Party and having one or more claims that covers a Product, or the manufacture, use, sale, offer for sale, or importation of a Product, in each case in the Territory, (except insofar as such action is a counterclaim to or defense of, or accompanies a defense of, a Third Party’s claim or assertion of infringement under Section 10.7, in which case the provisions of Section 10.7 shall govern), such Party shall so notify the other Party and the Parties shall promptly confer to determine whether to bring such action or the manner in which to settle such action. Aquinox shall have the exclusive right, but not the obligation, to bring at its own expense and in its sole control such action in the Retained Territory and Astellas shall have the exclusive right, but not the obligation, to bring at its own expense and in its sole control such action in the Licensed Territory. If Astellas does not bring such an action in the Territory, within [***] days of notification thereof pursuant to this Section 10.9.1 (or earlier, if required by the nature of the proceeding), then Aquinox shall have the right, but not the obligation, to bring, at Aquinox’s sole expense, such action. The Party not bringing an action under this Section 10.9.1 shall be entitled to separate representation in such proceeding by counsel of its own choice and at its own expense, and shall cooperate fully with the Party bringing such action at the request and expense of the Party bringing such action. Any awards or amounts received in bringing any such action shall be allocated between the Parties as provided in Section 10.6.2.6.

10.9.2 Parties’ Patent Rights. If a Aquinox Patent, Astellas Collaboration Patent or Joint Patent becomes the subject of any proceeding commenced by a Third Party within the

Territory in connection with an opposition, reexamination request, action for declaratory judgment, nullity action, invalidation action, interference, or other attack upon the validity, title, or enforceability thereof (except insofar as such action is a counterclaim to or defense of, or accompanies a defense of, an action for infringement against a Third Party under Section 10.6, in which case the provisions of Section 10.6 shall govern), then the Party responsible for filing, preparing, prosecuting, and maintaining such Patent as set forth in Section 10.4 shall control such defense, provided, however, that the costs associated with such defense shall be borne by the controlling Party. The controlling Party shall permit the non-controlling Party to participate in the proceeding to the extent permissible under Applicable Law, and to be represented by its own counsel in such proceeding, at the non-controlling Party’s expense. If either Party decides that it does not wish to defend against such action, then the other Party shall have a backup right to assume defense of such Third-Party action at its own expense. Any awards or amounts received in defending any such Third-Party action shall be allocated between the Parties as provided in Section 10.6.3.6.

11.2.7 Notwithstanding the foregoing, in the event a Party is required to make a disclosure of the other Party’s Confidential Information pursuant to Sections 11.2.2 through 11.2.4, it will, except where impracticable, give reasonable advance notice to the other Party of such disclosure, reasonably consider the comments of the other Party with respect to limiting such disclosure, and use efforts to secure confidential treatment of such Confidential Information at least as diligent as such Party would use to protect its own confidential information, but in no event less than reasonable efforts. In any event, the Parties agree to take all reasonable action to avoid the non-confidential disclosure of Confidential Information hereunder. Any information disclosed pursuant to Sections 11.2.2 through 11.2.4 shall remain the Confidential Information of the disclosing Party and subject to the restrictions set forth in this Agreement, including the foregoing provisions of this ARTICLE XI.

Exhibit 7:

Expedited Arbitration Procedures (Per Section 15.4)

If (i) [***] (an “Aquinox Material Adverse Effect”), or (b) Astellas believes that [***] (an “Astellas Material Adverse Effect”) (each of (a) and (b), a “Challenge”), then the Party believing that there would be such a material adverse effect (the “Challenging Party”) shall have the right, but not the obligation, to notify the other Party (the “Challenged Party”) in writing of such belief (a “Challenge Notice”). Such Challenge Notice shall set forth in reasonable detail the Challenging Party’s basis for such belief, including any supporting materials.

If a Challenge Notice is provided as set forth above, such dispute shall be finally settled by an impartial and independent Third Party expert (the “Expert”). The Expert shall be an expert in the field of pharmaceutical product Development and Commercialization as mutually agreed upon by the Parties in good faith. Before accepting the appointment, the Expert shall disclose to the Parties in writing any circumstances that might give rise to a reasonable basis for questioning the Expert’s impartiality or independence, or confirm in writing that no such circumstances exist. If the Parties are unable to agree on an Expert within [***] Business Days of the Challenged Party’s receipt of the Challenge Notice, the dispute shall be finally resolved by a panel of three (3) Experts, with each Party selecting one Expert and the two Experts selecting the third Expert, with such panel to be appointed within the following [***] Business Days and in accordance with the preceding sentence.

Within [***] Business Days following the selection of the Expert(s), each Party shall prepare and submit to each of the Expert(s) and the other Party a written report setting forth its position with respect to the resolution of the Challenge, together with all material information supporting its position. Each Party shall have [***] Business Days from receipt of the other Party’s submission to submit a written response thereto, which shall include any scientific and technical information in support thereof. The Expert(s) shall have the right to meet with the Parties, either alone or together.

No later than [***] Business Days after the designation of the Expert(s), or such longer period (not to exceed [***] Business Days after the designation of the Expert(s)) as the Expert(s) may require, taking into consideration the Parties’ need for expeditious resolution, the Expert(s) shall make a determination as to whether the Challenged Party’s exercise of its right of final decision under Section 3.3.2 would reasonably be expected to

EXECUTION VERSION

CONFIDENTIAL

result in an Aquinox Material Adverse Effect or Astellas Material Adverse Effect, as applicable. The Expert(s) shall provide the Parties with a written statement setting forth the basis of the determination in connection therewith. The Parties agree that such Expert’s(s’) determination shall be final and determinative. Each Party shall bear its own costs with respect to any proceeding under this Exhibit, provided that the Party against whom the Expert(s) rules shall bear all costs of the Expert(s).
