Upon written request from Licensee, MSK shall participate in a teleconference or an in-person meeting, during business hours, upon reasonable notice, attended by MSK personnel with decision-making authority to discuss issues related to the prosecution and/or maintenance of the Patent Rights in any jurisdiction. Any such meeting conducted in person shall take place at the offices of MSK.

7.4 The Parties agree that they share a common legal interest in obtaining valid, enforceable patents and that Licensee will maintain confidential all information received pursuant to this Article 7. In light of the shared interest of the parties, MSK and Licensee agree to maintain good communication as to all matters related to the terms and actions governed by this License Agreement and further agree to make reasonable efforts to resolve disagreements or disputes as to any aspect of this License Agreement through discussion among management personnel of each Party.

7.5 Licensee shall not challenge the validity or enforceability of any claim within the Licensed Patents and shall cause its Affiliates and Sublicensees to refrain from doing so.

ARTICLE 8

INFRINGEMENT

8.1 Monitoring. Licensee shall use commercially reasonable efforts to monitor third party infringement of the Patent Rights in the Field of Use. Licensee shall keep MSK timely informed of any activities by Licensee in regard hereto.

8.2 Actions. This Section 8.2 sets forth the parties’ right of enforcement and defense in relation to the Patent Rights.

(a) First Right. Licensee shall have the first right, but not the obligation, for the initiation, defense, and management of any adversarial legal proceeding relating to the Patent Rights in the Field of Use and Territory (including without limitation any declaratory judgment action, patent infringement action or opposition) during the Term, and will be responsible for all expenses related thereto. MSK shall join in any such action, at Licensee’s request and expense.

(b) Secondary Right. If Licensee does not wish to exercise either of the foregoing rights in (a), Licensee shall provide MSK with written notice that Licensee declines such right, and after receiving such notice, MSK shall have the secondary right to undertake such infringement action or defend against such challenge.

8.3 Cooperation; Settlement. To the extent either Party conducts any legal proceedings in relation to the enforcement or defense of the Patent Rights in the Field of Use and Territory, it shall keep the other Party reasonably informed of such proceedings. The other Party shall reasonably cooperate in any such legal proceedings, at the expense of the requesting Party. In any action conducted by MSK, Licensee will join as may be requested by MSK, and in any action conducted by Licensee, Licensee may affect joinder of MSK if MSK is an indispensable or necessary party under the applicable law. Notwithstanding anything in this Agreement to the contrary, no settlement, consent judgment, or other voluntary final disposition of any action by Licensee that admits the invalidity, unenforceability, or reduces the scope of the Patent Rights, or impairs the validity, enforceability or scope of the Patent Rights, may be entered into without the prior written consent of MSK in its sole reasonable discretion.

8.4 Costs and Recoveries. All costs of any action by either Party to enforce, or to defend against a challenge to, the Patent Rights shall be borne by such Party, which shall keep any sums recovered or obtained in connection therewith (whether as damages, reasonable royalties, license fees, or otherwise in judgment or settlement derived therefrom), except that in the case of actions commenced by Licensee, the excess of such sums over such costs shall be treated as Net Sales subject to MSK’s rights under this Agreement to collect royalties thereon. For the avoidance of doubt, Licensee may not deduct, from Net Sales any portion of Licensee’s costs or expenses related to any investigation, enforcement, defense, judgment or settlement of any such actions.

8.5 Third Party Patents. In the event Licensee is sued for patent infringement or, threatened with such suit, Licensee shall promptly notify MSK. In any such action, Licensee shall be fully responsible for all its costs, including expenses, judgments and settlements.

ARTICLE 9

ARTICLE 10

INDEMNIFICATION, PRODUCT LIABILITY

10.1 Licensee will indemnify, defend and hold harmless (and cause its Sublicensees to so indemnify, defend and hold harmless) MSK and its respective trustees, directors, officers, medical and professional staff, employees, students, and agents and their respective successors, heirs, and assigns (each an “Indemnitee”), against all third party claims and expenses (including legal expenses and reasonable attorney’s fees) arising out of the death of or injury to any person or persons, or out of any damage to property, against any infringement or misappropriation of intellectual property and against any other claim, proceeding, demand, expense and liability of any kind whatsoever resulting from the production, manufacture, sale, use, lease, consumption, or advertisement of Licensed Products hereunder or from a breach by Licensee of any of its representations, warranties or obligations under this Agreement, provided, however, that Licensee will not be obligated to indemnify, defend and hold harmless any Indemnitee against any claim, proceeding, demand, expense, or liability to the extent it arises out of, results from, or is increased by MSK’s gross negligence or willful misconduct.

ARTICLE 18

MISCELLANEOUS PROVISIONS

18.1 Governing Law. This Agreement shall be governed by and construed under the laws of the State of New York in all respects as such laws are applied to agreements among New York residents entered into and performed entirely within New York, without giving effect to conflict of law principles thereof. The Parties agree that any action brought by either Party under or in relation to this Agreement, including without limitation to interpret or enforce any provision of this Agreement, shall be brought in, and each Party agrees to and does hereby submit to the jurisdiction and venue of, any state or federal court sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein.

18.2 Successors and Assigns. This Agreement will inure to the benefit of the Parties and their respective successors and permitted assigns.

18.3 Severability. In the event that any provision(s) of this Agreement is(are) held to be invalid, illegal or unenforceable under any controlling body of the law, such invalidity, illegality, or unenforceability shall not in any way affect the validity, legality, or enforceability of the remaining provisions. The Parties will in such an instance use their best efforts to replace the invalid, illegal, or unenforceable provision(s) with valid, legal, and enforceable provision(s) that implement the purposes of this Agreement.

18.4 Waiver. The failure of either Party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition by the other Party.

18.5 Delays or Omissions. It is agreed that no delay or omission to exercise any right, power or remedy accruing to any Party, upon any breach, default or noncompliance by another Party under this Agreement shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring. It is further agreed that any waiver, permit, consent or approval of any kind or character on any Party’s part of any breach, default or noncompliance under this Agreement or any waiver on such Party’s part of any provisions or conditions of this Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement or otherwise afforded to any Party, shall be cumulative and not alternative.

18.6 Counterparts. This Agreement may be executed in any number of counterparts and each of such counterparts shall for all purposes be an original and all such counterparts shall together constitute but one and the same agreement.

18.7 Force Majeure. Neither Party shall lose any rights hereunder or be liable to the other Party for damages or losses (except for payment obligations) on account of failure of performance by the defaulting Party to the extent such the failure is occasioned by war, strike, fire, Act of God, earthquake, flood, lockout, embargo, governmental acts or orders or restrictions (except if imposed due to or resulting from the Party’s violation of law or regulations), failure of suppliers, or any other reason where failure to perform is beyond the reasonable control and not caused by the negligence, intentional conduct or misconduct of the nonperforming Party and the nonperforming party has exerted all reasonable efforts to avoid or remedy such force majeure; provided, however, that in no event shall a force majeure excuse performance for a period of more than six (6) months. For clarity, a failure to obtain funding shall not constitute a force majeure event.

18.8 Entire Agreement. This Agreement, including its attachments and exhibits (which attachments and exhibits are incorporated herein by reference), constitutes the entire understanding among and between the Parties with respect to the subject matter hereof, and supersedes all prior agreements and communications, whether written, oral or otherwise, including, for the avoidance of doubt, that certain side letter agreement entered into by and between the Parties and dated as of May 25, 2017, which is hereby terminated by the Parties. This Agreement may only be modified or supplemented in a writing expressly stated for such purpose and signed by the parties to this Agreement. It is expressly understood that and agreed that any waivers included in the Amendments remain in full force and effect.

Each Party hereto further agrees to indemnify the other Party hereto for any claims, losses or expenses resulting from such Party’s breach of the foregoing representation and warranty.

18.12 Construction and Interpretation. Words (including defined terms) denoting the singular shall include the plural and vice versa. The words “hereof’, “herein”, “hereunder” and words of the like import when used in this Agreement shall refer to this Agreement as a whole, and not to any particular provision of this Agreement. The term “include” (and any variant thereof), and the giving of examples, shall not be construed as terms of limitation unless expressly indicated by the context in which they is used. The headings in this Agreement shall not affect its interpretation. Except as expressly provided herein, the rights and remedies herein provided shall be cumulative and not exclusive of any other rights or remedies provided by law or otherwise. Each of the parties has had an opportunity to consult with counsel of its choice. Each provision of this Agreement shall be construed without regard to the principle of contra proferentum. If any provision of this Agreement is held to be invalid or unenforceable the validity of the remaining provisions shall not be affected. The parties shall replace the invalid or unenforceable provision by a valid and enforceable provision closest to the intention of the parties when signing this Agreement This Agreement was negotiated, and shall be construed and interpreted, exclusively in the English language.
