If either Party recovers monetary damages from any Third Party in an action approved by the Parties and brought under this Section 6.3(d)(ii), such recovery shall be allocated first to the reimbursement of any actual, unreimbursed costs and expenses incurred by the Parties in such litigation (including, for this purpose, a reasonable allocation of expenses of internal counsel), then pro rata in accordance with the aggregate amounts spent by both Parties, and any remaining amounts shall be split fifty percent (50%) to Nektar and fifty percent (50%) to BMS, unless the Parties agree in writing to a different allocation. In connection with any proceeding under this Section 6.3(d), neither Party shall enter into any settlement without the prior written consent of the other Party.

6.4 Infringement of Third Party Rights.

(a)Notice. If the activities relating to the Combined Therapy Trials become the subject of a claim of infringement of a patent, copyright or other proprietary right by a Third Party anywhere in the world, the Party first having notice of the claim shall promptly notify the other Party and, without regard to which Party is charged with said infringement and the venue of such claim, the Parties shall [***] confer to discuss the claim.

(b)Defense. If both Parties are charged with infringement pursuant to a claim described in Section 6.4(a), the Parties shall defend such claim jointly, unless they agree otherwise. If only one Party is charged with infringement, such Party will have the first right but not the obligation to defend such claim. If the charged Party does not commence actions to

defend such claim within [***] after being so charged, then the other Party shall have the right, but not the obligation, to defend any such claim. In any event, the non-defending Party sha ll reasonably cooperate with the Party conducting the defense of the claim and shall have the right to participate with separate counsel at its own expense, and the defending Party shall consider comments by the non-defending Party in good faith. The Part y defending the claim shall bear the cost and expenses of the defense of any such Third Party infringement claim and shall have sole rights to any recovery. If the Parties jointly defend the claim, Nektar shall bear fifty percent (50%), and BMS shall bear fifty percent (50%) of any costs and expenses of the defense of any such Third Party infringement claim; provided, however, that, notwithstanding the foregoing, if the claim relates solely to one Party’s Compound, such Party will bear one hundred percent (100%) of the costs and expenses of the defense of such claim, shall have sole rights to any recovery and shall have the sole right, but not the obligation, to defend, settle and otherwise handle the disposition of such claim. If either Party recovers mon etary damages from any Third Party while jointly defending the claim, such recovery shall be allocated first to the reimbursement of any actual, unreimbursed costs and expenses incurred by the Parties in such litigation (including, for this purpose, a reas onable allocation of expenses of internal counsel) pro rata in accordance with the aggregate amounts spent by both Parties, and any remaining amounts shall be split fifty percent (50%) to Nektar and fifty percent (50%) to BMS, unless the Parties agree in w riting to a different allocation. Neither Party shall enter into any settlement concerning activities under this Agreement or the Combined Therapy that affects the other Party’s rights under this Agreement or imposes any obligations on the other Party, in cluding any admissions of wrongdoing on behalf of the other Party, without such other Party’s prior written consent, not to be unreasonably withheld or delayed, except that a Party may settle any claim that solely relates to its Compound without the consen t of the other Party as long as such other Party’s rights under this Agreement are not adversely impacted (in which case, it will obtain such other Party’s prior written consent, not to be unreasonably withheld or delayed).

6.5 Combined Therapy Trial Regulatory Documentation. Subject to the license and other rights granted by each Party to the other Party pursuant to this Agreement, Nektar and BMS shall jointly own all right, title and interest in and to the Combined Therapy Trial Regulatory Documentation; provided, however, that BMS shall retain sole and exclusive ownership of any BMS Regulatory Documentation provided to Nektar under this Agreement that is submitted with or referenced in the Combined Therapy Trial Regulatory Documentation and that Nektar shall retain sole and exclusive ownership of any Nektar Regulatory Documentation that is submitted with or referenced in the Combined Therapy Trial Regulatory Documentation.

Notwithstanding the foregoing, Nektar hereby authorizes disclosure to Ono in accordance with Section 9.4 above. Notwithstanding the foregoing, nothing herein shall prevent or restrict Ono from making any disclosures of published Study Data disclosed to it by BMS pursuant to Section 9.4 or of the existence of this Agreement, in each case in order for Ono to comply with requirements of Applicable Law, the rules or regula tions of any securities exchange or listing entity on which its stock may be traded or pursuant to an order of a court or governmental entity to publicly disclose the existence of the Agreement and the Study Data.

under the Sunshine Laws. Therefore, as between the Parties, BMS will report payments or other tran sfers of value (“POTV”) made by Nektar or the CRO related to the conduct of the Combined Therapy Trials and any applicable associated contractor engagements as required under the Sunshine Laws, for each Combined Therapy Trial initiated prior to such date t hat Nektar becomes responsible for reporting POTV for studies sponsored by it. BMS shall request delayed publication for any reported POTV for the studies sponsored by Nektar as permitted under the Sunshine Laws and if consistent with BMS’s normal busines s practices. In the event Nektar becomes responsible for reporting POTV for studies sponsored by it in a given country during the Term, Nektar shall provide written notification to BMS, and the Parties will meet and confer to discuss how they wish to hand le reporting thereafter. Interpretation of the Sunshine Laws for purposes of reporting any POTV by a Party shall be in such Party’s sole discretion so long as the interpretation complies with Applicable Law.

(b)Nektar (i) will provide (to the extent in the possession of Nektar), or will utilize Commercially Reasonable Efforts to obligate and ensure that each CRO and other applicable Third Party contractors for a Combined Therapy Trial provides, BMS with any information requested by BMS as BMS may reasonably determine is necessary for BMS to comply with its reporting obligations under Sunshine Laws (with such amounts paid to, or at the direction of, each Recipient to be reported to BMS within a reasonable time period specified by BMS and agreed by Nektar) and (ii) will reasonably cooperate with, and will utilize Commercially Reasonable Efforts to obligate and ensure that each CRO and other applicable Third Party contractors for a Combined Therapy Trial reasonably cooperate with, BMS in connection with its compliance with such Sunshine Laws. The form in which Nektar provides any such information shall be mutually agreed but sufficient to enable BMS to comply with its reporting obligations and BMS may disclose any information that it believes is necessary to comply with Sunshine Laws. Without limiting the foregoing, BMS shall have the right to allocate payments or other transfers of value in connection with this Agreement in any required reporting under Sunshine Laws in accordance with its normal business practices. These obligations shall survive the expiration and termination of the agreement to the extent necessary for BMS to comply with Sunshine Laws.

(c)For purposes of this Section 9.6, “Sunshine Laws” means Applicable Laws requiring collection, reporting and disclosure of POTVs to certain healthcare providers, entities and individuals. These Applicable Laws may include relevant provisions of the Patient Protection and Affordable Health Care Act of 2010 and implementing regulations thereunder. “Recipients” means healthcare providers, teaching hospitals and/or any other Persons for whom transfers of value or payments must be reported under Sunshine Laws.

9.7 Destruction of Confidential Information. Upon expiration or termination of the Agreement, the receiving Party shall, upon request by the other Party, immediately destroy or return all of the other Party’s Confidential Information relating solely to its Compound as monotherapy (but not to the Combined Therapy or the Combined Therapy Study Data) in its possession; provided, however, that the receiving Party shall be entitled to retain one (1) copy of Confidential Information solely for record-keeping purposes and shall not be required to destroy

The Breaching Party shall have a period of [***] after receipt of such notice to cure such material breach (the “Cure Period”) in a manner reasonably acceptable to the Non-Breaching Party.

(b)If a Clinical Hold with respect to either the BMS Compound or the Nektar Compound should arise at any time after the Effective Date, the Parties will meet and discuss the basis for the Clinical Hold, how long the Clinical Hold is expected to last, and how they might address the issue that caused the Clinical Hold. If, after [***] of discussions following the Clinical Hold, either Party reasonably concludes that the issue is not solvable or that unacceptable and material additional costs/delays have been and/or will continue to be incurred in the conduct of the Combined Therapy Trial, then such Party may immediately terminate this Agreement.

12.5 Effect of Termination. Upon expiration or termination of this Agreement, (a) the licenses granted to each Party to conduct a Combined Therapy Trial in Sections 3.1 and 3.2 shall terminate, and (b) the Parties shall use reasonable efforts to wind down activities under this Agreement in a reasonable manner and avoid incurring any additional expenditures or non-cancellable obligations; provided that, in the case of termination pursuant to Section 12.4, Nektar may continue to dose subjects enrolled in any then ongoing Combined Therapy Trial through completion of the applicable Protocol if dosing is required by the applicable Regulatory Authority(ies) and/or Applicable Law(s). Any such wind-down activities will include the return to BMS, or destruction, of all BMS Compound provided to Nektar and not consumed in the Combined Therapy Trials. If applicable, upon termination of this Agreement, the Parties shall remain responsible pursuant to the terms of this Agreement for any expenses incurred prior to such termination and that are associated with terminating any ongoing clinical trial work and/or result from such ongoing activities under this Agreement solely to the extent such activities are deemed necessary by Nektar (after discussion at a meeting of the JDC) based on reasonable medical judgment to protect the health of subjects participating in any Combined Therapy Trial.

During the Exclusive Collaboration Period, except for Permitted Research (as defined below), Nektar will not (A) conduct any preclinical or clinical research with a Restricted Third Party regarding an anti-PD-1 antagonist or anti-PD-L1 antagonist, together with the Nektar Compound (a “Restricted Combination”), (B) license any rights under its proprietary intellectual property to any Restricted Third Party to enable the study of any Restricted Combination, (C) grant any right to a Restricted Third Party under its Nektar IND, NDA or other Regulatory Documentation for the Nektar Compound during the Exclusive Collaboration Period to enable a Restricted Third Party to research or develop a Restricted Combination, or (D) grant any right to a Third Party under the Combined Therapy Trial IND, during the Exclusive Collaboration Period, to enable a Restricted Third Party to research or develop a Restricted Combination. The foregoing shall not (1) restrict or preclude any combination studies between Nektar and any Third Party other than those containing a Restricted Combination, (2) restrict or preclude the out-license or sale of the Nektar Compound (provided that the licensee or acquirer of the Nektar Compound agrees to comply with the restrictions set forth herein) or (3) restrict or preclude Nektar from performing preclinical or clinical research using a Restricted Combination on its own or with any non-profit Entities (including university and academic research institutions) (collectively, “Permitted Research”), provided that with respect to clause (3) above, Nektar shall share with BMS during the Exclusive Collaboration Period any data generated from such preclinical or clinical research to the extent relating to a Restricted Combination and, in Nektar’s sole discretion, any other information related to a Restricted Combination, subject in each case to any conditions and restrictions that apply to Nektar’s use of such data and information.

b.BMS Exclusivity. Except with respect to those studies that are underway as of the Effective Date, as described on the attached Exhibit D, or Permitted IL2 Research (as defined below), during the Exclusive Collaboration Period, BMS will not conduct any preclinical or clinical research with a Restricted Third Party regarding the BMS Compound together with an IL2-based CD122 agonist (a “Restricted IL2 Combination”). The foregoing shall not (1) restrict or preclude any combination studies between BMS and any Third Party other than those containing a Restricted IL2 Combination (2) restrict or preclude the out-license or sale of the BMS Compound (provided that any such licensee or acquirer agrees to comply with the restrictions set forth herein) or (3) restrict or preclude BMS from performing preclinical or clinical research using a Restricted IL2 Combination on its own or with any non-profit Entities
