Subject to the other provisions of this Article 12, Nektar shall defend Daiichi Sankyo, its Affiliates and its Sublicensees and each of their respective officers, directors, agents, representatives and employees (collectively, “Daiichi Sankyo Parties”) from and against any Third Party Claims, and indemnify and hold harmless such Daiichi Sankyo Parties from and against any and all Losses that result from any such Third Party Claims, where and to the extent that such Third Party Claims are made or brought against any Daiichi Sankyo Party by or on behalf of a Third Party, and solely to the extent such Third Party Claim is based on or arises out of: (a) claims that (i) use of the Licensed Product in the BCBM Trial infringes the Intellectual Property Rights of a Third Party; or (ii) Commercialization of the Licensed Product as Developed by Nektar or its Affiliates for the Primary Indication in the Territory infringes the Intellectual Property Rights of a Third Party; (b) the breach of any obligation, covenant, warranty or representation made by Nektar under this Agreement or any Ancillary Agreement; (c) any violation of Applicable Law by Nektar, its Affiliates or any of their respective subcontractors or other agents in the course of their activities under this Agreement; (d) the Development of the Licensed Product for the Primary Indication in the Territory by or on behalf of Nektar; (e) the Commercialization of the Licensed Product outside the Territory; or (f) the gross negligence or willful misconduct of any Nektar Party, their subcontractors or other agents in the course of their activities under this Agreement; provided however, that Nektar shall not be required to defend, indemnify or hold harmless any Daiichi Sankyo Party to the extent that such Third Party Claim or Loss is attributable to any matter for which Daiichi Sankyo is obligated to indemnify a Nektar Party pursuant to Section 12.1 above.

12.3 Indemnification Procedures. A Person entitled to indemnification pursuant to either Section 12.1 or Section 12.2 will hereinafter be referred to as an “Indemnitee.” A Party obligated to indemnify an Indemnitee hereunder will hereinafter be referred to as an “Indemnitor.” In the event a Nektar Indemnitee or a Daiichi Sankyo Indemnitee is seeking indemnification under either Section 12.1 or Section 12.2, Nektar or Daiichi Sankyo, as applicable, will inform the Indemnitor of a Third Party Claim (an “Indemnification Claim Notice”) [***] after it receives notice of the Third Party Claim, it being understood and agreed that the failure to give notice of a Third Party Claim as provided in this Section 12.3 will not relieve the Indemnitor of its indemnification obligation under this Agreement except and only to the extent that such Indemnitor is actually and materially prejudiced as a result of such failure to give notice. Upon the written acknowledgement by the Indemnitor, within [***] following

receipt of such Indemnification Claim Notice acknowledging that such Third Party Claim is one with respect to which the Indemnitor is obligated to indemnify, the Indemnitee will permit the Indemnitor to assume direction and control of the defense of the Third Party Claim, and, at the Indemnitor’s expense, will cooperate as reasonably requested in the defense of the Third Party Claim. The Indemnitee will have the right to retain its own counsel at its own expense. The Indemnitor may not settle such Third Party Claim, or otherwise consent to an adverse judgment in such Third Party Claim without the Indemnitee’s prior written consent, not to be unreasonably withheld, conditioned or delayed; provided that the Indemnitor shall not require such consent with respect to the settlement of any Third Party Claim under which the sole relief provided is for monetary damages that are paid in full by the Indemnitor, which would not materially diminish or limit or otherwise adversely affect the rights, activities or financial interests of the Indemnitee or the Party to which that Person relates, and which does not result in any finding or admission of fault by the Indemnitee or the Party to which that Person relates. If the Indemnitor does not assume direction and control of the defense of the Third Party Claim, the Indemnitee may defend and settle such Third Party Claim (including consent to an adverse judgment in such Third Party Claim) without the Indemnitor’s prior written consent.

(c)Joint Patent Applications. With respect to applications for Patents on Joint Inventions that are neither Nektar Core Technology Inventions nor Daiichi Sankyo Core Technology Inventions (the “Joint Patent Applications”), the Parties shall determine which Party shall be responsible for Prosecuting Patents on behalf of both Parties (the “Responsible Party”) based on a good faith determination of the relative contributions of the Parties to the Joint Invention and the relative interests of the Parties in the Joint Invention. At least [***] prior to the contemplated filing of such Joint Patent Application, the Responsible Party shall submit a substantially completed draft of the Joint Patent Application to the other Party for its approval, which shall not be unreasonably withheld or delayed. Except as set forth below, the Parties shall share equally the costs of the Prosecution of all Joint Patent Applications. If either Party elects not to pay its portion of any shared costs for a Joint Patent Application or Patent issuing therefrom, the other Party may proceed with such Joint Patent Application in its own name and at its sole expense, in which case the Party electing not to pay its share of costs hereby agrees to transfer and assign and shall transfer and assign its entire right, title and interest in and to such Joint Patent Application to the other Party and such Invention shall be treated as a Sole Invention of the assignee for the purposes of Section 13.1(b).

(d)Further Actions. Each Party shall cooperate with the other Party to execute all documents and take all reasonable actions to effect the intent of this Section 13.1.

[***]

14.Enforcement of Patents.

14.1 Notice of Infringement. If either Party believes that a Third Party is infringing any of the Patents licensed to the other Party under this Agreement in the Territory, or is requesting a license or other right under such Patents in the Territory (“Third Party Infringing Activities”), such Party shall [***] notify the other Party in writing, identifying the alleged infringer and the alleged infringement complained of and furnishing the information upon which such determination is based.

14.2 Control of Enforcement. If any Third Party Infringing Activity infringes any Licensed Patent, then Nektar shall have the sole right and subject to this Section 14.2, the obligation, through counsel of its choosing, to take any measures it deems appropriate to stop such Third Party Infringing Activity that materially affects the Licensed Product in the Territory, including granting to the infringing Third Party adequate rights and licenses under the Licensed Patents necessary for continuing such activities; [***]. The Parties will cooperate in good faith to determine the appropriate measures to stop any Third Party Infringing Activity that infringes any jointly owned Joint Inventions.

14.3 Cooperation. Upon reasonable request by the Party permitted to take legal action against Third Party Infringing Activities under this Article 14 (the “Enforcing Party”), the other Party shall give the Enforcing Party all reasonable information and assistance, including allowing the Enforcing Party reasonable access to its files and documents and personnel who may have possession of relevant information.

14.4 Recovery. Any amounts recovered with respect to Third Party Infringing Activities, whether by settlement or judgment, shall be used first to reimburse the Parties for their reasonable costs and expenses in making such recovery (which amounts shall be allocated pro rata if insufficient to cover the totality of such expenses), with any remainder being paid to the Parties [***].

15.Potential Third Party Actions.

15.1 Invalidity or Unenforceability Defenses or Actions.

(a)Notice. If a Third Party asserts that any Patent licensed to the other Party under this Agreement is invalid or unenforceable in the Territory, whether as a defense or as a counterclaim in a legal action or in a declaratory judgment action or similar action or claim (any such defense, counterclaim, claim, or action, an “Invalidity Action”), then the Party first becoming aware of the Invalidity Action shall [***] give written notice to the other Party. For the avoidance of doubt, in no event shall any interferences, reissue proceedings, oppositions and re-examinations be deemed an Invalidity Action, and the conduct and management of any such matters shall be governed by the provisions of Article 14.

(b)Control of Action. [***].

15.2 Third Party Litigation. In the event of any actual or threatened suit against Nektar or its Affiliates or licensees, or Daiichi Sankyo or its Affiliates, Sublicensees or customers alleging that the Development, Manufacturing or Commercialization of the Licensed Product in the Territory infringes the Intellectual Property Rights of any Third Party (an “Infringement Suit”), the Party first becoming aware of such Infringement Suit shall [***] give written notice to the other Party.

In the event that such Party is deemed a Debtor, the other Party may terminate this Agreement by providing written notice to the Debtor. All rights and licenses granted under or pursuant to this Agreement by Nektar are, and shall be deemed to be, for purposes of Section 365(n) of the Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101 of the Bankruptcy Code.

Parties agree that the Parties, as licensees of such rights under this Agreement, shall retain and may fully exercise all of their rights and elections under the Bankruptcy Code. If a Party is the Debtor, then the other Party shall be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property necessary to enjoy the benefits of this Agreement and all embodiments of such intellectual property, and if not already in the non-Debtor Party’s possession, such shall be promptly delivered to such Party upon its written request therefor and in the case where Nektar is the Debtor, the same shall not affect Daiichi Sankyo’s payment or other obligations to Nektar hereunder.

(e)Notice period.

(a)Each Party acknowledges and agrees that the restrictions set forth in Section 2.6 and Article 10 of this Agreement are reasonable and necessary to protect the legitimate interests of the other Party, and that the other Party would not have entered into this Agreement in the absence of such restrictions, and that any breach or threatened breach of any provision of Section 2.6 or Article 10 will result in irreparable injury to the other Party for which there may be no adequate remedy at law.
