At any given time under this Agreement, Novartis may only hold rights to a maximum of four Global Target Pairs (or, in the case where Xencor has exercised its Opt-In Right and not exercised its Opt-Out Right pursuant to Section 5.3.7, three such Global Target Pairs). From time to time during the Global Target Selection /Replacement Period, Novartis may notify Xencor in writing of Targets that Novartis desires to designate as a Global Target Pair for the purposes of this Agreement (each, a “Proposed Global Target Pair”) and, within [...***...], Xencor will advise Novartis whether such Target pairs are Available. If the Target pair is available, then such Target pair will be deemed to be a Global Target Pair. If the Proposed Global Target Pair is not Available, then such Proposed Global Target Pair will not be deemed a Global Target Pair. If Novartis questions why a Proposed Global Target Pair is not Available, upon request, Xencor shall promptly provide reasonable evidence of such un-Availability, which evidence may be provided to outside counsel or outside consultant engaged by Novartis (and who will enter an appropriate confidentiality agreement with Xencor prior to receipt of such evidence) to confirm such status, with such outside counsel or consultant engaged by Novartis permitted to disclose to Novartis only whether or not it agrees with the Xencor determination as to Availability. In the event of a dispute with regard to Availability, such dispute shall be resolved by Expedited Arbitration.

3.1.3.Substitution Rights. For each Global Target Pair, Novartis shall have the one-time right, during the Global Target Pair Selection/Replacement Period, to substitute another Target pair that are Available Target pairs for such Global Target Pair, provided that (i) Novartis may only make such substitution once per Global Target Pair (i.e., Novartis may make four such substitutions) and (ii) a given Global Target Pair cannot be substituted once a Global Licensed Antibody against such Global Target Pair achieves [...***...]. Without limiting the foregoing, Novartis shall also have the right to substitute up to [...***...] Global Target Pairs at any time due to a Research Failure.

concerning potential reservation of potential Targets, including the identity of any Target proposed to be an Fc Target in confidence and the Fc Gatekeeper will not disclose any such information to Xencor, its Related Parties, or to any Third Party unless specifically instructed to do so by Novartis. Novartis shall be solely responsible for all invoices by the Fc Gatekeeper and shall timely pay the Fc Gatekeeper’s invoices as set forth in the Fc Gatekeeper engagement letter.

3.2.1.2.Fc Target Unavailable List. [...***...].

3.2.1.3.Novartis Selection Notice and Process. From time to time during the Fc Target Selection Period, Novartis may submit to the Fc Gatekeeper a written notice (the “Fc Notice”) identifying a Target (including a Target that would be Specifically Bound by a Bispecific Antibody) that it wishes to designate as a Fc Target for the purposes of this Agreement (each, a “Proposed Fc Target”).

(a)Within [...***...] after receiving such Fc Notice, the Fc Gatekeeper shall inform Novartis if such Proposed Fc Target is Available. Such Proposed Fc Target shall be confirmed as an Fc Target for the purposes of this Agreement if such Target or Bispecific (including a Target that would be Specifically Bound by a Bispecific Antibody) does not appear on the then-current Fc Target Unavailable List. If such Proposed Fc Target does appear on the then-current Fc Target Unavailable List then the Fc Gatekeeper shall so notify Novartis, without providing additional details, and such Proposed Fc Target shall not become an Fc Target.

(b)If Novartis questions why a Proposed Fc Target is on the Fc Target Unavailable List, Xencor shall promptly provide reasonable evidence of such un-Availability, which evidence may be provided to an outside counsel or outside consultant engaged by Novartis who is reasonably acceptable to Xencor (and who will enter an appropriate confidentiality agreement with Xencor prior to receipt of such evidence) to confirm such status, with such outside counsel or consultant permitted to disclose to Novartis only whether or not it agrees with the Xencor determination as to Availability.

In addition, if either Party is or becomes subject to a legal obligation to a Regulatory Authority or other Governmental Authority (such as a corporate integrity agreement or settlement agreement with a Governmental Authority), then the other Party will perform such activities as may be reasonably requested by the obligated Party, at the obligated Party’s sole expense, to enable the obligated Party to comply with its legal obligation to such Regulatory Authority with respect to the Licensed Products.

12.5.1.2.During the Term, each Party covenants to the other Party that it and its Affiliates’ employees and contractors, shall not, in connection with the performance of their respective obligations under this Agreement, directly or indirectly through Third Parties, pay, promise or offer to pay, or authorize the payment of, any money or give any promise or offer to give, or authorize the giving of anything of value to a Public Official or other Person for purpose of obtaining or retaining business for or with, or directing business to, any Person, including either Party (it being understood that, without any limitation to the foregoing, such Party, and to its knowledge, its and its Affiliates’ employees and contractors, has not directly or indirectly promised, offered or provided any corrupt payment, gratuity, emolument, bribe, kickback, illicit gift or hospitality or other illegal or unethical benefit to a Public Official or any other Person in connection with the performance of such Party’s obligations under this Agreement, and shall not, directly or indirectly, engage in any of the foregoing). .

promptly, but in no event less than [...***...] thereafter, provide written notice thereof to the other Party and, if possible, grant the other Party the right (but not the obligation) to cure such alleged breach.

14.4.4.3.Each Party will have the right to consult with the other Party regarding any such action controlled by such other Party, in each case at such first Party’s sole cost and expense. If a Party elects to so be involved, the controlling Party will provide the other Party and its counsel with an opportunity to consult with the controlling Party and its counsel regarding the prosecution of such action (including reviewing the contents of any correspondence, legal papers or other documents related thereto), and the controlling Party will take into account reasonable and timely requests of the other Party regarding such enforcement or defense.

For the avoidance of doubt, termination of this Agreement will not affect any SDEA, which will continue to survive so long as any Licensed Products thereunder are being Commercialized.

Notwithstanding the foregoing, either Party may, without the other Party’s written consent, assign this Agreement and its rights and obligations hereunder in whole or in part to an Affiliate or in whole to a party that acquires, by or otherwise in connection with, merger, sale of assets or otherwise, all or substantially all of the business of the assigning Party to which the subject matter of this Agreement relates. The assigning Party will remain responsible for the performance by its assignee of any obligation hereunder so assigned. An assignment to an Affiliate will terminate, and all rights so assigned will revert to the assigning Party, if and when such Affiliate ceases to be an Affiliate of the assigning Party. Any purported assignment in violation of this Section 16.2 will be void.

16.3.Governing Law. The Agreement will be construed and the respective rights of the Parties determined in accordance with the substantive Laws of the State of New York, notwithstanding any provisions of New York Law or any other Law governing conflicts of laws to the contrary.

16.4.Arbitration.

-137-

***Confidential Treatment Requested

16.4.1. Disputes. Except as otherwise expressly set forth in this Agreement, including Section 2.5.3, disputes of any nature arising under, relating to, or in connection with this Agreement (“Disputes”) will be resolved pursuant to this Section 16.4.

16.4.2.Dispute Escalation. In the event of a Dispute between the Parties, the Parties will first attempt to resolve such Dispute by negotiation and consultation between themselves or at the JSC. In the event that such Dispute is not resolved on an informal basis within [...***...] from receipt of the written notice of a Dispute, any Party may, by written notice to the other, have such Dispute referred to the Executive Officers, who will attempt to resolve such Dispute by negotiation and consultation for a [...***...] period following receipt of such written notice.

16.4.3.Full Arbitration. Except as otherwise expressly set forth in this Agreement, in the event the Parties have not resolved such Dispute within [...***...] of receipt of the written notice referring such Dispute to the Executive Officers, either Party may at any time after such [...***...] period submit such Dispute to be finally settled by arbitration administered in accordance with the procedural rules of the American Arbitration Association (the “AAA”) in effect at the time of submission, as modified by this Section 16.4. The arbitration will be governed by the Laws of the State of New York. The arbitration will be heard and determined by three arbitrators who are retired judges or attorneys with at least 20 years of relevant experience in the pharmaceutical and biotechnology industry, each of whom will be impartial and independent and will not have worked for or on behalf of either Party for at least five years. Each Party will appoint one arbitrator and the third arbitrator will be selected by the two Party-appointed arbitrators, or, failing agreement within [...***...] following appointment of the second arbitrator, by the AAA. Such arbitration will take place in New York, New York. The arbitration award so given will, absent manifest error, be a final and binding determination of the Dispute, will be fully enforceable in any court of competent jurisdiction, and will not include any damages expressly prohibited by Section 13.5. Novartis will pay the fees, costs and expenses for the arbitrator it chooses, Xencor will pay the fees, costs and expenses for the arbitrator it chooses, and the Parties will share payment for the third arbitrator. Except in a proceeding to enforce the results of the arbitration or as otherwise required by Law or securities exchange, neither Party nor any arbitrator may disclose the existence, content or results of any arbitration hereunder without the prior written consent of both Parties.

16.4.4.Expedited Arbitration.

16.4.4.1.If a Party exercises its rights under this Agreement to refer a dispute to expedited arbitration (an “Expedited Dispute”), then the Parties will follow the expedited dispute resolution process in this Section 16.4.4 (and not the dispute resolution process in Section 16.4.3 of this Agreement) (“Expedited Arbitration”). The Parties agree and acknowledge that any good faith dispute under Expedited Arbitration will not be deemed to be a material breach of this Agreement.

16.4.4.2.The Expedited Dispute will be submitted to fast-track, binding arbitration in accordance with the following:

-138-

***Confidential Treatment Requested

The Parties will appoint a single arbitrator to be selected by mutual agreement. If the Parties are unable to agree on an arbitrator, the Parties will request that the AAA select the arbitrator. The arbitrator will be a professional in business or licensing experienced in the valuation of biopharmaceutical products with at least 10 years of experience in the pharmaceutical and life sciences industries, including the conduct of research, development and commercialization collaborations. The cost of the arbitration will be borne equally by the Parties. Except in a proceeding to enforce the results of the arbitration or as otherwise required by Laws, neither Novartis nor Xencor nor any arbitrator may disclose the existence, content or results of any arbitration hereunder without the prior written agreement of Novartis and Xencor.

(b)Within [...***...] after such matter is referred to arbitration, each Party will provide the arbitrator with a proposal and written memorandum in support of its position regarding the Expedited Dispute, as well as any documentary evidence it wishes to provide in support thereof (each a “Brief”) and the arbitrator will provide each Party’s Brief to the other Party after it receives it from both Parties.

(c)Within [...***...] after a Party submits its Brief, the other Party will have the right to respond thereto. The response and any material in support thereof will be provided to the arbitrator and the other Party.

(d)The arbitrator will have the right to meet with the Parties as necessary to inform the arbitrator’s determination and to perform independent research and analysis. Within [...***...] of the receipt by the arbitrator of both Parties’ responses (or expiration of the [...***...] period if any Party fails to submit a response), the arbitrator will deliver his/her decision regarding the Expedited Dispute in writing, provided that the arbitrator will select one of the resolutions proposed by the Parties.

16.4.5.Injunctive Relief. Notwithstanding the dispute resolution procedures set forth in this Section 16.4, in the event of an actual or threatened breach of this Agreement, the aggrieved Party may seek provisional equitable relief (including restraining orders, specific performance or other injunctive relief), without first submitting to any dispute resolution procedures hereunder.

16.4.6.Tolling. The Parties agree that all applicable statutes of limitation and time-based defenses (such as estoppel and laches), as well as all time periods in which a Party must exercise rights or perform obligation hereunder, will be tolled once the dispute resolution procedures set forth in this Section 16.4 have been initiated and for so long as they are pending, and the Parties will cooperate in taking all actions reasonably necessary to achieve such a result. In addition, during the pendency of any Dispute under this Agreement initiated before the end of

The Exhibits and Schedules attached hereto may be amended, or any term hereof modified, only by a written instrument duly-executed by authorized representatives of both Parties hereto.

16.6.Severability. If any provision hereof should be held invalid, illegal or unenforceable in any respect in any jurisdiction, the Parties hereto will substitute, by mutual consent, valid provisions for such invalid, illegal or unenforceable provisions, which valid provisions in their economic effect are sufficiently similar to the invalid, illegal or unenforceable provisions that it can be reasonably assumed that the Parties would have entered into this Agreement with such valid provisions. In case such valid provisions cannot be agreed upon, the invalid, illegal or unenforceable of one or several provisions of this Agreement will not affect the validity of this Agreement as a whole, unless the invalid, illegal or unenforceable provisions are of such essential importance to this Agreement that it is to be reasonably assumed that the Parties would not have entered into this Agreement without the invalid, illegal or unenforceable provisions.

16.7.Headings. The captions to the Sections hereof are not a part of this Agreement, but are merely for convenience to assist in locating and reading the several Sections hereof.
