The JEC shall meet at least [***], or at such other frequency as the JEC agrees (and it may appoint working teams to meet more frequently), provided that either Party through its JEC Co-Chair may request a meeting of the JEC at any time upon [***] notice to the other Party, with the understanding that the other Party will use reasonable efforts to comply with such request but such other Party will not be in breach of this Agreement in the event that it is unable to comply with such request but is using reasonable efforts to conduct a JEC meeting as promptly as practicable.

Upon request by either Party, such meetings will be held by audio or video teleconference; provided that face-to-face meetings shall occur at least [***], alternating between Princeton, NJ and San Francisco, CA unless otherwise agreed upon by the Parties. There must be a minimum of [***] from each Party at any meeting of the JEC to constitute a quorum for decision-making. No fewer than [***] prior to each meeting, and in any event as soon as reasonably practicable, each Party shall use good faith efforts to disclose to the other Party any proposed agenda items together with appropriate supporting information. The Alliance Managers shall alternate responsibility for preparing and circulating definitive minutes of each meeting of the JEC. Such minutes shall provide a description, in reasonable detail, of the discussions at the meeting, a list of material actions and decisions made by the JEC, a list of action items made by the JEC and a list of material issues not resolved by the JEC. The Alliance Manager who drafts the minutes shall provide the other Alliance Manager and each Party’s JEC Co-Chair with the initial draft meeting minutes, who shall return the draft with any proposed changes, and this process shall be repeated until a final version of the meeting minutes is agreed upon and signed (or acknowledged as final via email) by the two JEC Co-Chairs. The Parties shall reasonably cooperate to complete and agree upon a final version of meeting minutes within [***] from the date of the relevant meeting. The final version of the meeting minutes shall be signed (or acknowledged as final via email) by the two JEC Co-Chairs, and each Party shall be provided with a copy of the final meeting minutes for its safekeeping. A reasonable number of additional representatives of a Party may attend meetings of the JEC in advisory capacity with the prior written consent of the other Party; provided that any JEC meetings that includes representatives of either Party who are not JEC members may, at the request of any JEC member, include a closed session consisting of only JEC members and Alliance Managers. All representatives to the JEC or attending JEC meetings shall be subject to confidentiality and nonuse restrictions at least as restrictive as those set forth herein.

2.3Responsibilities of the JEC. The JEC shall have overall responsibility for the collaboration of the Parties pursuant to this Agreement, including (a) overseeing the Development and Commercialization of the Nektar Compounds and Products; (b) reviewing, resolving, and/or approving such matters as are referred to it by the Alliance Managers, JFC, JDC, JCC, JMC; and (c) performing such other duties as are expressly assigned to the JEC in this Agreement.

(a)Performance of Development Program. Nektar and BMS will act in good faith, using Commercially Reasonable Efforts, to perform their assigned tasks and responsibilities as described in the Development Program.

(b)Joint Development Plan. The Joint Development Plan describes the work to be pursued by Nektar and BMS during each Calendar Year, which plan shall include a

Development Budget for each Collaboration Study. The Joint Development Plan may be updated at any time by mutual agreement of the Parties at a meeting of the JDC or by written agreement (including by email acknowledgment) of the JDC Co-Chairs without a meeting. Any material amendments to the Joint Development Plan (“Material Amendments”), including the following, will be subject to mutual agreement of the Parties at a meeting of the JDC:

(iv)approving any investigator-initiated study or investigator-initiated research for a Monotherapy or Combined Therapy;

(vii)changing the compounds used in combination with the Product in a Collaboration Study;

(ix)changing the primary end points or key secondary end points for the Collaboration Study;

(x)materially changing the number of patients to be enrolled in a Collaboration Study;

(xi)material changes in the Statistical Analysis Plan or a Bioanalysis Plan; and

(xii)any other matters that the JDC or the Parties may agree are Material Amendments.

(c)Neither Party shall be required to continue a Collaboration Study if a Party (i) reasonably deems there to be a Material Safety Issue for such Collaboration Study or (ii) receives communications from a Regulatory Authority ordering or suggesting the discontinuation of such Collaboration Study. Prior to the discontinuation of such Collaboration Study, representatives of the JDC shall meet and discuss in good faith such Material Safety Issue or such Regulatory Authority communication.

(a)The Joint Development Plan will set out each Collaboration Study to be performed under the Joint Development Plan, including the initial NKTR-214 Clinical Trials set forth in the initial Joint Development Plan (each such initial NKTR-214 Clinical Trials, an “Initial Trial”). The JDC shall determine the Lead Party and Sponsor for each Collaboration Study and the latest date by which each Collaboration Studies must have its first patient enrolled (the “Diligence Date”) (subject to Allowable Delays), provided that, unless otherwise agreed by the Parties, Nektar shall be the Lead Party and Sponsor for each Monotherapy Collaboration Study. Notwithstanding anything to the contrary in this Agreement, the Lead Party and Sponsor (if different) for each Initial Trial shall be set forth in the initial Joint Development Plan. Each Initial Trial shall commence as soon as practicable and the last Diligence Date for all such trials is fourteen (14) months from the Effective Date, subject to tolling for Allowable Delays. The Parties intend to agree on end points for each Initial Trial that are intended, if met, to be sufficient to support a Nektar Compound Filing for Regulatory Approval.

(b)The JDC shall consider the capabilities of each Party and how to maximize the efficiency of the applicable Collaboration Study when determining the Lead Party for such Collaboration Study; provided that Nektar shall maintain a substantial operational role with respect to the overall clinical Development of the Product.

(c)If all the Collaboration Studies for a particular Collaboration Therapy do not meet their agreed primary end points, such Collaboration Therapy will, unless otherwise agreed by the Parties, be removed from the Joint Development Plan and Schedule 1.43 by written notice from either Party to the other and the Parties shall use reasonable efforts to wind down activities related solely to such removed Collaboration Studies and will apply in this respect the principles set forth in Section 16.6. If BMS is the Lead Party conducting one or more Collaboration Studies in a particular Collaboration Therapy and does not meet its Diligence Date (subject to Allowable Delays) for all of the Collaboration Studies in such Collaboration Therapy, such Collaboration Studies will remain in the Joint Development Plan, but the restrictions set forth in Section 7.3(d) will no longer apply to such Collaboration Therapy.

(d)Each Collaboration Study shall be conducted in accordance with a protocol (each, a “Protocol”) to be drafted by its Lead Party. Such Protocol shall be mutually agreed upon by the Parties at a meeting of the JDC. Any substantive amendments to a Protocol will be subject to mutual agreement of the Parties at a meeting of the JDC or by written agreement (including by email acknowledgment) of the JDC Co-Chairs without a meeting.

(e)The JDC shall decide under which IND a Collaboration Study shall be conducted under; provided that, unless otherwise agreed by the Parties:

(i)if a Collaboration Study is for a Nektar Compound for use as Monotherapy, such trial shall be conducted under an existing IND for which Nektar is the Sponsor or a new IND for which Nektar shall be the Sponsor;

(ii)if a Collaboration Study is for NKTR-214 for use as a Combined Therapy, such trial shall be conducted under either (A) an existing IND for which Nektar is the Sponsor or (B) if a new IND is required, a new IND for which the Lead Party shall be the Sponsor; and

(iii)if such Collaboration Study is for a Nektar Compound (other than NKTR-214) for use as a Combined Therapy, such trial shall be conducted under a new IND for which the Lead Party shall be the Sponsor.

(iv)Nektar IND. Nektar shall have complete legal interest in and control of each Nektar IND. Without limiting the obligation to share Net Profits under this Agreement, in no event will Nektar be required to obtain the consent of BMS to transfer or encumber any Nektar IND, and Nektar shall not have any obligation to share with BMS any consideration received in connection with the sale, license, use or other conveyance of any Nektar IND, provided that the transferee or encumbrance holder agrees to abide by the terms and conditions of this Agreement. Nektar shall have complete control as to any Right of Cross-Reference granted by Nektar to a Third Party solely with respect to any portion of a Nektar IND relating to a Nektar Compound for use as monotherapy.

(v)Combined Therapy Collaboration IND. Each Party shall have a beneficial one-half interest in each Combined Therapy Collaboration IND; provided, however, that: (A) in no event will either Party be required to obtain the consent of the other Party to transfer or encumber its interest in a Combined Therapy Collaboration IND; provided that (1) the transferee or encumbrance holder agrees to abide by the terms and conditions of this Agreement, (2) any transfer occurs only in connection with, and to the same transferee of, a transfer of all of a Party’s rights in its applicable Single Agent Compound, and (3) each Party provide written notice of such transfer or encumbrance to the other Party within thirty (30) calendar days of such transfer or encumbrance; and (B) the Lead Party shall be the sole holder of all legal interests in the applicable Combined Therapy Collaboration IND, and without limiting the obligation to share Net Profits under this Agreement, neither Party shall have any obligation to share with the other Party any consideration received in connection with the sale, license or use of its interest in such Combined Therapy Collaboration IND where permitted by this Agreement. Each Party is permitted to grant any Third Party a Right of Cross-Reference with respect to any portion of a Combined Therapy Collaboration IND relating to a Nektar Compound’s use in an Independent Study (and Nektar will cooperate and grant such Right of Cross-Reference solely with respect to any portion of a Nektar IND relating to a Nektar Compound’s use in an Independent Study, whether Nektar or BMS is the Lead Party). Each Party shall provide a Right of Cross-Reference to its existing respective INDs or future INDs for its respective Single Agent Compound(s) as necessary to allow Combined Therapy Collaboration Studies to be conducted under applicable Nektar INDs or Combined Therapy Collaboration INDs. For the avoidance of doubt, each Party shall be responsible for (X) drafting and updating as necessary the investigator’s brochure for its respective Single Agent Compound(s) and (Y) filing all necessary Regulatory Documentation to the existing or

future INDs for its respective Single Agent Compound(s), including the submission to such existing or future INDs of Serious Adverse Events and adverse drug reaction cases emerging from any Collaboration Study or any Independent Study.

(f)Each Party will make available and promptly disclose to the other Party all results of the work conducted by such Party pursuant to the Development Program, and this Agreement, and will keep such records (paper and electronic) as described herein. Each Party will maintain records of the results in sufficient detail and in good scientific manner appropriate for patent purposes, and in a manner that properly reflects all work done and results achieved in the performance of the Development Program (including all data, such as minutes from dose escalation meetings with any Regulatory Authority and all final clinical study reports, in the form required to be maintained under any applicable governmental regulations).

3.7Dispute Resolution. The representatives of the JDC shall attempt in good faith to reach consensus on all matters properly brought before the JDC. Except as otherwise provided in this Agreement, if, after a good faith, reasonable and open discussion among the members of the JDC, the JDC is unable to agree on a matter that has been properly before it for a period of [***] and that calls for a decision, either Party may refer the dispute (a “JDC Dispute”) to the JEC for resolution. If the JEC is unable to reach a resolution within [***] of the referral of the JDC Dispute to the JEC, either Party may refer such JDC Dispute to the Executive Officers for resolution. If the Executive Officers are unable to reach a resolution within [***] of such referral then:

(a)if such JDC Dispute regards whether or not to commence a Clinical Trial as a new Collaboration Study (i.e., include a Clinical Trial (other than an Initial Trial) into the scope of the Joint Development Plan), then such Clinical Trial [***];

(b)if such JDC Dispute regards the initial Protocol and its contents (further to Section 3.2(d)) or the initial budget for any Collaboration Study, in each case before the commencement of such applicable Collaboration Study, then [***];

(c)if such JDC Dispute occurs subsequent to the commencement of a Collaboration Study, and relates to either (1) a material amendment requiring mutual agreement proposed by either Party to an agreed-upon Protocol or protocol synopsis, CRO Agreement, Bioanalysis Plan or Statistical Analysis Plan relating to such Collaboration Study or (2) any other matter relating to the strategy, conduct, rationale, or safety of such Collaboration Study, there shall be no decision on the matter and the then-existing terms of the applicable Protocol, protocol

synopsis, CRO Agreement, Bioanalysis Plan or Statistical Analysis Plan relating to such Collaboration Study shall govern. Notwithstanding the foregoing, neither Party shall be required to continue its involvement in a Collaboration Study if a Party reasonably deems there to be a Material Safety Issue for such Collaboration Study.

Each Party has the right to conduct preclinical and Phase I Studies (but not if such study could also be considered a registrational study) of any Fixed Dose Combination Product at its own cost. If the Parties agree (each at their sole discretion) to jointly Develop or Commercialize any Fixed Dose Combination Product, such Development or Commercialization will be conducted in accordance with a separate agreement, or an amendment to this Agreement, negotiated between the Parties. For clarity, no Party shall be obligated to collaborate with the other Party or to agree on any terms with the other Party with respect to any Fixed Dose Combination Product.

(b)Alternative Formulations. Each Party has the right to conduct preclinical and non-registrational studies and Clinical Trials of any alternative formulation or method of administration of the Nektar Compound or Product (including subcutaneous formulations) at its own cost. If the Parties agree (each at their sole discretion) to jointly Develop or Commercialize any alternative formulations or methods of administration of the Nektar Compound or Product, such Development and Commercialization will be conducted in accordance with a separate agreement, or an amendment to this Agreement, negotiated between the Parties. For clarity, no Party shall be obligated to collaborate with the other Party or to agree on any terms with the other Party with respect to any such alternative formulation or method of administration and neither

Party has any right to seek Regulatory Approval of or Commercialize any alternative formulations or methods of administration of the Nektar Compound or Product under this Agreement.

(c)Each Party shall keep the JDC reasonably informed as to the progress of any activities conducted pursuant to this Section 3.9.

(c)Each Party shall be responsible for day-to-day implementation of the Commercialization activities with respect to the Product for which it has or otherwise is assigned responsibility under this Agreement or the Commercialization Plan and Budget and shall keep the other Party reasonably informed as to the progress of such activities, as determined by the JCC.

The Product Brand Strategy must comply with each Party’s applicable SOPs, the Commercialization Plan and Budget, Applicable Laws and Regulatory Approvals. If the Product Brand Strategy Working Team cannot agree upon certain matters relating to the Product Brand Strategy, the matter may be referred to (A) the JCC or (B) for legal and compliance matters, the legal or compliance departments of the Parties, and then to the JCC for resolution, subject in this case to the final approval of the Parties’ respective compliance officers and legal departments, provided that if the Parties’ compliance officers or legal departments are unable to reach an agreement on the matter referred to them in accordance with the immediately preceding sentence, then the Parties shall adopt the approach of the Party with the more conservative compliance or legal position regarding such matter.

(ii)Nektar shall develop the relevant sales, promotion, market access and advertising materials relating to the Nektar Combinations for use in the Territory by Nektar and its Affiliates, provided that such materials, to the extent that they relate to the Product, shall be consistent with the Product Brand Strategy.

competitively sensitive Confidential Information with respect to the Commercialization of Combined Therapies.

(a)The Parties shall Commercialize the Product in the Territory under trademarks selected by the JCC and Controlled by Nektar, provided that Nektar shall have final decision making authority in relation to the selection of such trademark. The Parties shall Commercialize all Products in the Territory under brands, logos, trade dress and other trademarks selected by the JCC, subject to Nektar’s final decision making authority, except that BMS shall have the ability to finally reject any trademark that it reasonably believes is too similar to the registered trademark of any BMS Asset (collectively, the “Product Marks”), provided that the Product packaging and inserts shall include the logos and corporate names of both Parties in a manner to be agreed by the Parties. Product Marks may not use, incorporate or be confusingly similar any trademarks, trade names, service marks, logos, slogans, or trade dress, including corporate names, Controlled by BMS or any of BMS’s Affiliates without BMS’s prior written consent.

(b)BMS shall display symbols and notices clearly and sufficiently indicating the Product Marks’s trademark status and ownership. All proprietary rights and goodwill associated with BMS’s use of the Product Marks shall inure to the benefit of Nektar. BMS shall not (and shall cause its Affiliates and sublicensees not to): (i) use the Product Marks, either directly or indirectly, in any promotional materials, packaging, or Labelling without Nektar’s prior review and written consent in accordance with Section 8.9(g), such consent not to be unreasonably withheld or delayed; (ii) publish or disseminate any promotional materials or Labelling that is inconsistent in any material respect with those previously reviewed and approved by Nektar; (iii) establish any Internet domain name or URL incorporating any Product Mark without Nektar’s prior written consent; (iv) use the Product Marks in combination with any other name or trademark in a manner that creates a combination trademark; (v) contest the validity of, or take any action that a reasonable person would believe would impair any part of Nektar’s ownership of the Product Marks or diminish or dilute their distinctiveness or validity; (vi) challenge Nektar’s ownership of the Product Marks and/or registration thereof; or (vii) attempt to register any Product Mark or any trademark confusingly similar to any Product Mark as a trademark in BMS’s own name.

limited warranty and disclaimers, if any. Nektar and BMS shall each ensure that its and its Affiliates’ sales representatives do not make any statements, claims or undertakings to any Person with whom they discuss or promote the Products that are not consistent with, nor provide or use any Labelling, literature or other materials other than, those promotional materials currently approved for use by the JCC in the Territory.

Nektar may exercise the BMS Combination Commercialization Option in any of such countries in the Major Markets by written notice to BMS indicating the percentage of and types of Commercialization resources or services Nektar would provide (not to exceed [***] of the aggregate Commercialization resources dedicated to the Commercialization of the BMS Combinations in the applicable Commercialization Plan and Budget, provided that BMS shall not be required to modify its sales force structure or size as a result of the exercise of the BMS Combination Commercialization Option (it being understood that the Parties shall work together in good faith to optimize efficiency of sales force activities and resources directed to the BMS Combinations)) at any time prior to the date that is [***] prior to the estimated date of First Commercial Sale of Product in such market, as reasonably estimated by the Parties, but in no event earlier than [***]. If Nektar does not timely exercise its BMS Combination Commercialization Option then, the BMS Combination Commercialization Option shall expire with respect to such Major Market country. All costs associated with the BMS Combination Commercialization resources or services to be provided by Nektar following exercise of the BMS Combination Commercialization Option will be included in an amended Commercialization Plan and Budget, and the allocation of such costs to a Product shall be based on an equitable allocation of such

efforts to the Product versus other promotional activities being undertaken by the applicable Nektar employees and representatives. The methodology for such allocation shall be determined by the JCC. For the avoidance of doubt, any Commercialization resources or services (including direct-to-consumer advertisements) provided or performed by Nektar pursuant to this Section 8.12 shall be subject to the other provisions of this Agreement and, in particular, Sections 8.6(b) and 8.9(g)(iii), and the standards and guidelines determined by BMS, as lead Party for the Commercialization of the BMS Combinations pursuant to Section 8.9(c)(i).

Nektar, in consultation with BMS, through the JDC, JCC or JMC, as applicable, shall decide whether to conduct a recall in any market in the Territory (except in the case of a government mandated recall, when Nektar may act without such advance notice but, shall notify BMS as soon as possible) and the manner in which any such recall shall be conducted (and in the event of any disagreement regarding a recall in the Territory, the approach that is more conservative shall control). Each Party will make available to the other Party, upon request, all of such Party’s (and its Affiliates’) pertinent records that such other Party may reasonably request to assist such other Party in effecting any recall.

(a)During the Term, Nektar and BMS shall share global Commercialization profits and losses with respect to each Product as follows: (i) the BMS share shall equal thirty-five percent (35%) of the Net Profit, whether positive or negative (the “BMS Share of Net Profit”); and (ii) the Nektar share shall equal sixty-five percent (65%) of the Net Profit, whether positive or negative (the “Nektar Share of Net Profit”). Notwithstanding the proceeding sentence, solely for the first twelve (12) Calendar Quarters following the First Commercial Sale of the first Product, for any Calendar Quarter in which Net Profit is negative, an amount equal to fifteen percent (15%) of the Net Profit for any such Calendar Quarter (a “Loss Carry-Forward”) shall be borne by BMS on behalf of Nektar and carried over to subsequent Calendar Quarters in which Net Profit is positive, to be set off against Nektar Share of Net Profit and retained by BMS in such positive Calendar Quarter and any subsequent positive Calendar Quarters. Notwithstanding anything to the contrary, in the event of a Change of Control of Nektar, [***].

(b)For territories that are not Major Markets, if the JFC agrees, the Parties may agree to convert the profit share set forth above in Section 9.4(a) into an equivalent royalty to be paid to the Party that does not book the Product sales, provided that neither Party has any obligation to consent to such conversion.

(a)The JFC shall prepare for JCC approval reporting and reconciliation procedures for Commercialization and Product revenue (“Revenue Reporting and Reconciliation Procedures”) that will provide both Parties with sufficient information to record appropriate reserves, adjustments and other accruals required, under each Party’s accounting policies, including for Nektar to properly state Net Product Sales of the Product on a monthly basis in accordance with Nektar’s accounting policies.

(b)On the [***] after the end of each Calendar Quarter, each Party shall use best efforts to report to the other Party estimated Net Product Sales incurred during such Quarter.

(c)Within [***] after the end of each Calendar Quarter, each Party shall provide to the other Party its estimated Allowable Commercialization Expenses incurred by such Party for each Product during such Calendar Quarter in each country in Territory, in accordance with U.S. GAAP, to allow for the calculation of estimated Net Profits for such Calendar Quarter. Each Party shall report to the other Party, within [***] after the end of each Quarter, the actual Net Product Sales and Allowable Commercialization Expenses incurred by such Party for each Product during such Calendar Quarter in each country in the Territory in a manner sufficient to enable the other Party to comply with its Finance and Accounting Compliance and on a line item basis consistent with the budgetary line items set forth in the Commercialization Plan and Budget (the “Quarterly Report”). Such Quarterly Report shall specify in reasonable detail all deductions allowed in the calculation of such Net Product Sales and all expenses included in Allowable Commercialization Expenses for such Product. If requested by a Party, any invoices or other supporting documentation for any payments to a Third Party in respect of Allowable Commercialization Expenses that individually exceed [***] (or such other amount as may be specified by the JEC from time to time) shall be promptly provided not more than [***] after receipt of a request therefor.

made by one Party to the other Party so that a single reconciliation payment is made. To the extent any payments between the Parties include any element of Net Profit, such payments shall be taken into account for purposes of determining the ultimate settlement of Net Profit between the Parties.

(e)In determining the amount of Net Profit payment to be made with respect to a given country, the Parties shall also take into account any payments made by either Party to the other in such country (or its Affiliate) pursuant to any other agreement between the Parties or their Affiliates in consideration of Commercialization efforts in such country for the applicable period.

(f)Notwithstanding anything to the contrary in this Section, on a Calendar Year basis, the Parties shall not share or reimburse any Allowable Commercialization Expenses in excess of the amounts allocated for such Calendar Year in the Commercialization Plan and Budget and each Party will be solely responsible for Allowable Commercialization Expenses it incurs in excess of such budget; provided, however, that Allowable Commercialization Expenses in excess of such budget shall be included in the calculation of Net Profits to be shared by the Parties if [***].

(g)The JFC shall also determine if a quarterly, nonbinding estimated Net Profit report consistent with a Party’s internal reporting standards should be provided for planning purposes, but which would not be binding or used to determine or make any payments.

Upon request by either Party, such meetings will be held by audio or video teleconference. There must be a minimum of [***] from each Party at any meeting of the JFC. No fewer than five (5) Business Days prior to each meeting, and in any event as soon as reasonably practicable, each Party shall use good faith efforts to disclose to the other Party any proposed agenda items together with appropriate supporting information. The JFC Co-Chairs or Alliance Managers of each Party shall alternate responsibility for preparing and circulating definitive minutes of each meeting of the JFC. Such minutes shall provide a description, in reasonable detail, of the discussions at the meeting, a list of material actions and decisions made by the JFC, a list of action items made by the JFC and a list of material issues not resolved by the JFC. The Alliance

Manager who drafts the minutes shall provide the other Alliance Manager and each Party’s JFC Co-Chair with the initial draft meeting minutes, who shall return the draft with any proposed changes, and this process shall be repeated until a final version of the meeting minutes is agreed upon and signed (or acknowledged as final via email) by the two JFC Co-Chairs.

9.7Procedures For Development Cost Reporting and Reconciliation: Collaboration Studies and Independent Studies.

(a)Subject to Section 6.4, Development Costs initially shall be borne by the Party incurring the Development Cost, subject to reimbursement as provided in this Section 9.7. Each Party shall calculate and maintain records of Development Costs incurred by it and its Affiliates in accordance with procedures to be established by the JFC and approved by the JDC. The procedures for quarterly information sharing, reporting of actual results, quarterly reconciliation, reasonable cost forecasting, and other finance and accounting matters related to Development Costs for Collaboration Studies will be determined by the JFC (the “Development Cost Reconciliation Procedures”). The Development Cost Reconciliation Procedures will enable each Party to achieve and maintain Finance and Accounting Compliance. With respect to each Collaboration Study, each Party shall provide to the other Party, within [***] of the end of each Calendar Quarter, the estimated Collaboration Study Development Costs incurred in accordance with U.S. GAAP during such Calendar Quarter by such Party. A final report of actual Collaboration Study Development Costs incurred in accordance with U.S. GAAP during such Calendar Quarter by such Party will be provided within [***] of the end of each Calendar Quarter. Such report shall specify in reasonable detail all expenses included in such Collaboration Study Development Costs during such Calendar Quarter. Within [***] of the end of each Calendar Quarter, or for the last Calendar Quarter in a Calendar Year, within [***] of the end of such Calendar Year, amounts for Collaboration Study Development Costs will be billed to the Party that has paid less than its share of such Collaboration Study Development Costs and such Party

shall make a reconciling payment to the other Party to achieve the applicable sharing of such Collaboration Study Development Costs. If reasonably requested by the other Party, each Party shall make every reasonable attempt to accommodate the request and provide copies of any applicable invoices that individually exceed [***].

(b)Within [***] following the receipt of such report, unless a different timeframe is mutually agreed to by the JFC Co-Chairs, each Party shall have the right to request reasonable additional information related to the other Party’s, its Affiliates’, and Third Party Collaborators’ Collaboration Study Development Costs during such Calendar Quarter in order to confirm that such other Party’s spending is in conformance with the Development Budget and this Agreement. Upon a receipt of a request for additional information, the Party receiving such request shall attempt to comply with the request for additional information as quickly as practicable.

(c)The Parties shall use [***] to discuss and resolve any disputed amounts with respect to Collaboration Study Development Costs incurred or accrued by a Party within [***], unless a different timeframe is mutually agreed to by the JFC Co-Chairs, following the receipt by each Party of the other Party’s report under this Section 9.7.

(d)Notwithstanding the foregoing, on a Calendar Year basis, the Parties shall not share or reimburse any Collaboration Study Development Costs (other than Clinical Manufacturing Costs, which shall not be capped by this Section 9.7(d)) in excess of the amounts allocated for such Calendar Year in the Development Budget and each Party will be solely responsible for such Collaboration Study Development Costs it incurs in excess of the amounts set forth in the Development Budget; provided, however, that Collaboration Study Development Costs in excess of the Development Budget shall be included in the calculation of Collaboration Study Development Costs to be shared by the Parties if [***].

(e)Nektar’s share of Collaboration Study Development Costs that it is responsible for under the Joint Development Plan is subject further to the Development Cost Cap and limitations set forth in Section 6.4, and any payments required of Nektar or BMS (as applicable) shall be adjusted to account for the Development Cost Cap and the reimbursement thereof to BMS in accordance with Article 6.

(f)The procedures for annual reporting of actual results, annual review and discussion of potential discrepancies, annual reconciliation, cost forecasting, and other finance and accounting matters related to Opt-Out Development Costs will be determined by the JFC (the “Opt-Out Development Cost Reconciliation Procedures”). The Opt-Out Development Cost Reconciliation Procedures will provide enough information (subject to Third Party confidentiality restrictions, if any) to enable the non-funding Party to comply with financial reporting requirements under Applicable Law. In any event, each Party shall submit to the JFC by [***], a report (in an Independent Study-by-Independent Study format), in such reasonable detail and format as is established by the JFC, of all Opt-Out Development Costs incurred by such Party during such Calendar Year and the full budget, remaining amount of budget, and forecasted costs for the following Calendar Year associated with each such Independent Study. Within [***]

following the receipt of such report, unless a different timeframe is mutually agreed to by the JFC Co-Chairs, each Party shall have the right to request reasonable additional information related to the other Party’s and its Affiliates’ Opt-Out Development Costs during such Calendar Year. The JFC shall establish (subject to the Parties’ mutual agreement with respect thereto) additional reasonable procedures for the Parties to share estimated Opt-Out Development Costs for each Calendar Quarter prior to the end of such Calendar Quarter, to enable each Party to appropriately review, account for and/or disclose its potential future obligation of Opt-Out Development Costs for financial reporting purposes.

9.8Certain Tax Matters. The Parties intend that the arrangements between the Parties hereunder shall be treated as a partnership for U.S. federal and state income tax purposes only. As soon as practicable after the Effective Date but no later than [***], the Parties shall enter into a separate agreement that will cover tax matters (the “Tax Matters Agreement”) including provisions designating the tax representative for the partnership, governing the preparation and filing of tax returns, review of the tax returns, the Parties rights and obligations under audit and contest, document retention and other items that are customarily covered by an agreement of this type.

9.9Currency of Payments; Payment Method. Except as otherwise provided in this Agreement, all amounts owed by a Party under this Agreement shall be paid by such Party via electronic funds transmission of immediately available funds in U.S. dollars to the account designated in writing to such Party by the other Party. Conversion of amounts recorded in a currency other than U.S. dollars shall be performed in a manner consistent with each Party’s normal practices used to prepare its audited financial statements for internal and external reporting purposes. All payments by one Party to another Party under this Agreement shall be paid by electronic funds transmission. Each Party shall provide payment method information to the JFC.

9.10Interest on Late Payments. Any undisputed payments or portions thereof that are not paid on the date such payments are due, as provided in this Agreement, shall bear interest at the rate of [***] in which such payments are overdue, or [***], if less, in each case calculated on the number of days such payment is delinquent, compounded monthly.

9.11Withholding of Taxes. BMS agrees that the initial payment set forth in Section 9.1(a), all Development Milestone Payments and all Commercial Milestone Payments set forth in Section 9.2 and Section 9.3, and all other payments to Nektar under this Agreement, shall be paid from a United States domiciled entity for tax purposes; provided, however, that if any such payments are to be made from an entity domiciled outside of the United States, BMS must provide Nektar with notice at least [***] in advance of such payment to enable Nektar to meet requirements under Applicable Law and IRS Form 8802. Without modifying the preceding sentence, any withholding of taxes levied by tax authorities on the payments by BMS to Nektar hereunder that are required by Applicable Law to be deducted from such payments to Nektar will be deducted by BMS from the sums otherwise payable by it hereunder for payment to the proper tax authorities on behalf of Nektar, and BMS will pay the taxes to the proper taxing authority and send evidence of the obligation together with proof of tax payment to Nektar on a timely basis following that tax

payment. Such taxes will be borne by Nektar. BMS agrees to reasonably cooperate with Nektar in the event Nektar claims exemption from such withholding or seeks refunds or deductions under any double taxation or other treaty or agreement from time to time in force, such cooperation to include providing receipts of payment of such withheld tax or other documents reasonably available to BMS.

9.12Indirect Taxes. The Parties shall discuss applicable mechanisms for minimizing such taxes to the extent possible in compliance with Applicable Law. In addition, the Parties shall cooperate in accordance with Applicable Law to minimize indirect taxes (such as value added tax, sales tax, consumption tax and other similar taxes) in connection with this Agreement.

9.13Financial Records. Each Party will keep, and will cause its Affiliates and sublicensees to keep, complete, true and accurate books and records in accordance with its accounting standards, and to maintain Finance and Accounting Compliance, in relation to Development Costs, Net Product Sales and Net Profit. Each Party will keep, and will cause its Affiliates and sublicensees to keep, such books and records for at least [***] following the Calendar Quarter to which they pertain or as otherwise required by Applicable Law.

9.14Audit. At the request (and expense) of a Party, the other Party shall permit a nationally recognized independent certified public accountant appointed by such requesting Party and reasonably acceptable to the other Party (provided that such accountant shall not be retained or compensated on a contingency basis and shall have entered into a confidentiality agreement with the Party to be audited), at reasonable times and upon reasonable notice, to examine those records as may be reasonably necessary (as determined by the auditor) to determine, with respect to any Calendar Year ending not more than [***] prior to a Party’s request, the accuracy, correctness or completeness of any Development Costs for Collaboration Studies (including, for clarity, Opt-Out Development Costs reimbursed by the applicable Party pursuant to Section 7.4), Net Product Sales, and Allowable Commercialization Expenses. The foregoing right of review may be exercised [***] per year and [***] with respect to each such periodic report and payment. The Party requesting the audit shall submit an audit plan, including audit scope, to the Party to be audited for such audited Party’s approval, which shall not be unreasonably withheld or delayed, prior to audit implementation. The auditor shall keep confidential any information obtained during such inspection and shall report to the requesting Party and the audited Party only the amounts of such Development Costs, Net Product Sales, and Allowable Commercialization Expenses. If it is determined that additional payments are owed or due during such period, the audited Party will pay the requesting Party (with interest subject to Section 9.10) the additional payments, or the requesting Party will pay (with interest subject to Section 9.10) the audited Party the overpaid amounts within [***] of the date the auditor’s written report is received by the Party that requested the audit. The fees charged by the auditor will be paid by the Party requesting the audit unless such inspection reveals any unfavorable variance for the audited period of [***] or more, in which case the audited Party will pay the reasonable fees of the auditor. Once a Party has conducted a review and audit of the other Party pursuant to this Section 9.14 in respect of any given period, it may not subsequently re-inspect the other Party’s or its Affiliates’ records in respect of such period,

unless a subsequent audit of a separate reporting period uncovers fraud on the part of the audited Party that is reasonably expected to have been occurring during the prior audited period.

determines in good faith is necessary to be disclosed to comply with Applicable Law or the rules or regulations of any securities exchange on which such Party’s stock may be listed, or pursuant to an order of a court or governmental entity.

(b)Nektar and BMS agree to collaborate to publicly disclose, publish or present (i) top-line results from each Collaboration Study, limited if possible to avoid jeopardizing the future publication of the Study Data at a scientific conference or in a scientific journal, solely for the purpose of disclosing, as soon as reasonably practicable, the safety or efficacy results and conclusions that are material to either Party under applicable securities laws, and (ii) the conclusions and outcomes (the “Results”) of each Collaboration Study at a scientific conference as soon as reasonably practicable following the completion of such Collaboration Study, subject in the case of (ii) to the following terms and conditions. The Party proposing to disclose, publish or present the Results shall deliver to the other Party a copy of (A) any abstract or press release at least [***] before submission to a Third Party and (B) any proposed slide presentation, publication, poster presentation or any other disclosure, publication or presentation at least [***] before submission to a Third Party. The reviewing Party shall determine whether any of its Confidential Information that may be contained in such disclosure, publication or presentation should be modified or deleted, whether to file a patent application on any Nektar Asset Invention (solely with respect to Nektar) or BMS Asset Invention (solely with respect to BMS), Joint Collaboration Invention or Joint Third Party Invention disclosed therein. If practicable, the disclosure, publication or presentation shall be delayed for an additional [***] if the reviewing Party reasonably requests such extension to allow time for the preparation and filing of relevant patent applications. If the reviewing Party reasonably requests modifications to the disclosure, publication or presentation to prevent the disclosure of a material trade secret or proprietary business information, the publishing Party shall edit such publication to prevent the disclosure of such information prior to submission of the disclosure, publication or presentation. In the event of a disagreement as to content, timing and/or venue or forum for any disclosure, publication or presentation of the Results, such dispute (a “Publication Dispute”) shall be referred to the JEC; provided that, in the absence of agreement after such good faith discussions, and upon expiration of the additional [***]-period (to the extent provided pursuant to the above), (1) academic collaborators engaged by Nektar in connection with the performance of the Collaboration Studies may publish Collaboration Study Data obtained by such academic collaborator solely to the extent that such ability to publish such Collaboration Study Data is set forth in an agreement between Nektar and such academic collaborator relating to the conduct of Collaboration Studies and (2) the publishing Party may proceed with the disclosure, publication or presentation provided that such disclosure, publication or presentation is consistent with its internal publication guidelines and customary industry practices for the publication of similar data. Authorship of any publication shall be determined based on the accepted standards used in peer-reviewed academic journals at the time of the proposed disclosure, publication or presentation. The Parties agree that they shall make reasonable efforts to prevent publication of a press release that could jeopardize the future publication of Study Data at a scientific conference or in a scientific journal but in no way will this or any other provision of this Agreement supersede the requirements of any Applicable Law or the rules or regulations of any securities exchange or listing entity on which a Party’s stock is listed

(including any such rule or regulation that may require a Party to make public disclosures about interim or ongoing results of a Collaboration Study). Notwithstanding the foregoing, Nektar hereby authorizes disclosure to Ono in accordance with Section 12.4 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 12.4 or of the existence of this Agreement, in each case in order for Ono to comply with requirements of Applicable Law, the rules or regulations 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.

(a)For purposes of compliance with reporting obligations under Sunshine Laws, Nektar represents that it is not, as of the Effective Date, subject to reporting obligations under the Sunshine Laws. Therefore, as between the Parties, BMS will report payments or other transfers of value (“POTV”) made by Nektar or the CRO related to the conduct of the Collaboration Studies and any applicable associated contractor engagements as required under the Sunshine Laws, for each Collaboration Study initiated prior to such date that 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 business 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 handle 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 each Collaboration Study for which Nektar is the Lead Party 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 each Collaboration Study for which Nektar is the Lead Party 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 12.6, “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 or any other Persons for whom transfers of value or payments must be reported under Sunshine Laws.

(a)If, after completing the review process by the Executive Officers described in Section 15.1, the Parties do not fully settle a Commercial/Financial Dispute, and a Party wishes to pursue the matter, each such Commercial/Financial Dispute will be resolved exclusively in the manner set forth in this Section 15.2. The Parties will endeavor for up to [***]to agree upon a single individual to serve as a Commercial/Financial Dispute Arbitrator. As used in this Agreement, the “Commercial/Financial Dispute Arbitrator” shall be [***]. If the Parties cannot

mutually agree on the Commercial/Financial Dispute Arbitrator within such [***], then [***] to serve as the Commercial/Financial Dispute Arbitrator. The process for selecting a Commercial/Financial Dispute Arbitrator shall be completed in no more than [***]. Once selected, the Commercial/Financial Dispute Arbitrator shall render a final binding decision on the Commercial/Financial Dispute [***] (or such other time as the Parties may mutually agree in writing) of the appointment of said arbitrator as set forth in this Section 15.2.

(b)The process for resolving the Commercial/Financial Dispute shall be conducted in accordance with the American Arbitration Association Arbitration Rules and shall be held, on an alternating basis, per arbitrated Commercial/Financial Dispute, between San Francisco, CA and New York, NY (unless the Parties otherwise mutually agree to telephone or video conference, or a different location). The language of the arbitration shall be English. Within [***] following selection of the Commercial/Financial Dispute Arbitrator, the Parties each shall provide a memorandum to the Commercial/Financial Dispute Arbitrator describing the Commercial/Financial Dispute, the background and supporting factual materials in support of such Party’s proposed outcome, and a proposed ruling that decides the outcome of the Commercial/Financial Dispute for issuance by the Commercial/Financial Dispute Arbitrator, if adopted (a “Ruling”). If a Party fails to timely submit a memorandum and proposed Ruling, the Commercial/Financial Dispute Arbitrator shall interpret such failure as the Party having accepted the proposed Ruling of the other Party, and shall adopt such other Party’s Ruling as the decision of the Commercial/Financial Dispute Arbitrator.

(c)The Commercial/Financial Dispute Arbitrator shall determine what discovery, if any, shall be permitted based on the memoranda submitted by the Parties, consistent with the goal of limiting the cost and time which the Parties must expend for discovery; provided the Commercial/Financial Dispute Arbitrator shall permit such discovery as he or she deems necessary to permit an equitable resolution of the dispute. The Commercial/Financial Dispute Arbitrator further is entitled to engage experts and other consultants to assist him or her in rendering a decision regarding the Commercial/Financial Dispute. Such experts or consultants shall not have any voting power and shall be independent under the same standard as applies to the Commercial/Financial Dispute Arbitrator. The costs of resolving the Commercial /Financial Dispute, including administrative and arbitrator’s fees, shall be shared [***].

(d)At the conclusion of discovery (if any) and review, the Commercial/Financial Dispute Arbitrator shall adopt one of the proposed Rulings submitted by the Parties as the decision of the Commercial/Financial Dispute Arbitrator in respect of the Commercial/Financial Dispute. The Commercial/Financial Dispute Arbitrator must select for his or her decision one of the Parties’ Rulings, and is not entitled to change such Ruling or issue an alternative award. The Parties agree that the Ruling issued by the Commercial/Financial Dispute Arbitrator decision shall be the sole, exclusive and binding remedy between them regarding the Commercial/Financial Dispute. Any award may be entered in a court of competent jurisdiction for a judicial recognition of the decision and an order of enforcement.

Arbitration Matters. If a Dispute that constitutes an Arbitration Matter remains unresolved after escalation to the senior executives as described above, either Party may refer the matter to arbitration as described herein, the results of which shall be binding upon the Parties

. Any arbitration under this Agreement shall be conducted under the auspices of the American Arbitration Association (“AAA”) by a panel of three (3) arbitrators pursuant to that organization’s Commercial Arbitration Rules then in effect. The fees and expenses of the arbitrators shall be [***]. Each Party shall bear the fees and expenses of its legal representation in the arbitration. The arbitral tribunal shall not reallocate either the fees and expenses of the arbitrators or of the Parties’ legal representation. The arbitration shall be held in New York, NY, USA, which shall be the seat of the arbitration. The language of the arbitration shall be English. Notwithstanding anything to the contrary in this Agreement, each Party shall be entitled to recover its attorneys’ fees and arbitration fees and expenses to the extent it is successful in bringing an action to enforce its rights to indemnification under this Agreement against the other Party.

This Agreement shall commence on the Effective Date, and unless earlier terminated pursuant to this Article 16 or any other termination right expressly stated in this Agreement, shall expire: (a) with respect to the Parties’ obligation to collaborate in the Development of Nektar Compounds and Products, upon the expiration of the last to expire Patent Right that Covers a Nektar Compound; and (b) for all other matters, upon the expiration of all payment obligations set forth in Article 9 (the “Term”).

(a)Notice and Cure Period. If a Party (the “Breaching Party”) is in material breach, the other Party (the “Non-Breaching Party”) shall have the right to give the Breaching Party notice specifying the nature of such material breach. 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. For the avoidance of doubt, this provision is not intended to restrict in any way either Party’s right to notify the other Party of any other breach or to demand the cure of any other breach. The Parties agree that for purposes of this Section 16.2, a breach of the representations or warranties of a Party under this Agreement shall not be a cause for termination of this Agreement unless such breach has had or would be reasonably expected to have a material adverse effect on the Development, Manufacture or Commercialization of the Product.

(b)Termination Right. The Non-Breaching Party shall have the right to terminate this Agreement (either in its entirety or only in part) as further described below, upon written notice, in the event that the Breaching Party has not cured such material breach within the Cure Period, provided, however, that if such breach is capable of cure but cannot reasonably be cured within the Cure Period, and the Breaching Party notifies the non-Breaching Party of its intent

to cure such material breach, commences actions to cure such material breach within the Cure Period and thereafter diligently continues such actions, the Breaching Party shall have an additional [***] to cure such breach. If a Party contests such termination pursuant to the dispute resolution procedures under Section 15.1, such termination shall not be effective until a conclusion of the dispute resolution procedures in Section 15.1, as applicable, resulting in a determination that there has been a material breach that was not cured within the Cure Period (or, if earlier, abandonment of the dispute by such Party). For clarity, such material breach of this Agreement may apply to (i) this Agreement in its entirety, in which case the termination right pursuant to this Section 16.2(b), and Section 16.6 (as applicable), shall apply to the entire Agreement; (ii) a specific Product or Single Agent Compound in which case the termination right pursuant to this Section 16.2(b), and Section 16.6 (as applicable), shall apply only to such affected Product or Single Agent Compound; or (iii) a specific Region or country within a Region, in which case the termination right pursuant to this Section 16.2(b), and Section 16.6 (as applicable), shall apply only to such affected Region as a whole. As used in this Section 16.2, “Region” shall mean each of the following groups of countries: [***].

16.3Termination for Bankruptcy. Either Party will have the right to terminate this Agreement in the event of a general assignment for the benefit of creditors of the other Party, or if proceedings of a case are commenced in any court of competent jurisdiction by or against such other Party seeking (a) such other Party’s reorganization, liquidation, dissolution, arrangement or winding up, or the composition or readjustment of its debts, (b) the appointment of a receiver or trustee for or over such other Party’s property, or (c) similar relief in respect of such other Party under any law relating to bankruptcy, insolvency, reorganization, winding up or composition or adjustment of debt and, in each case of clauses (a) through (c) such proceedings shall continue un-dismissed, or an order with respect to the foregoing shall be entered and continue unabated, for a period of more than [***].

16.4Termination or Suspension of Collaboration Study due to Material Safety Issue or Clinical Hold.

(a)Either Party shall have the right to suspend or terminate the applicable Collaboration Study immediately upon written notice if it reasonably deems it necessary to protect the safety, health or welfare of subjects enrolled in any Collaboration Study due to the existence of a Material Safety Issue. In the event of a termination of a Collaboration Study due to a Material Safety Issue, prior to the terminating Party providing written notice, each Party’s safety committee shall, to the extent practicable, meet and discuss in good faith the safety concerns raised by the terminating Party and consider in good faith the input, questions and advice of the non-terminating Party, but should any dispute arise in such discussion, the dispute resolution process set forth in Section 3.7 or Article 15 shall not apply to such dispute and the terminating Party shall have the right to issue such notice and such termination shall take effect without the Parties first following the procedures set forth in Section 3.7 or Article 15.

(b)If a Clinical Hold with respect to any of the BMS Assets, Nektar Assets or Third Party Assets used in a Collaboration Study 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 or delays have been or will continue to be incurred in the conduct of the applicable Collaboration Study, then such Party may immediately suspend or terminate the applicable Collaboration Study.

(a)BMS shall have the right to terminate this Agreement in its entirety (but not in part) without cause at any time after the completion, discontinuation or cancellation of all of the Initial Trials in accordance with this Agreement in the event that no Regulatory Approval is obtained on the basis of the results of any of the Initial Trials, subject to a six (6) month prior notice to Nektar.

(b)Provided that all of the Initial Trials have been completed, discontinued or cancelled in accordance with this Agreement, BMS shall have the right to terminate this Agreement in its entirety (but not in part) without cause at any time after the first (1^st) anniversary of the First Commercial Sale of the first Product, subject to a twelve (12) month prior notice to Nektar after such First Commercial Sale.

(c)In the event of a Change of Control of Nektar, BMS shall have the right to terminate this Agreement in its entirety (but not in part) without cause at any time after the First Commercial Sale of the first Product, subject to a six (6) month prior notice to the Nektar Successor after such First Commercial Sale.

(d)At Nektar’s request after the effective date of the termination of this Agreement pursuant to this Section 16.5, BMS will provide Nektar, free of charge, with the BMS Compound, ipilimumab and any other BMS Asset owned by BMS (subject to any Third Party limitations or obligations, including as may be further limited following a Change of Control pursuant to Section 17.12(b)) for which a BLA has been Filed or for which a BLA Regulatory Approval has been provided, for use in Clinical Trials of a Combined Therapy of a combination of Nektar Assets with such BMS Assets (whether or not also with any Third Party Assets), pursuant to one or more clinical collaboration agreements to be entered into by Nektar and BMS.

Neither Party will be deemed to be in breach of this Agreement or otherwise be liable to the other Party by reason of any delay in

performance or nonperformance of any of its obligations hereunder to the extent that such delay and nonperformance is due to any Force Majeure of which it has notified the other Party; provided, however, that such delay or nonperformance shall be excused for up to a maximum of [***], after which time the Parties will negotiate in good faith any modifications of the terms of this Agreement that may be necessary to arrive at an equitable solution.

It is agreed that no waiver by a Party hereto of any breach or default of any of the covenants or agreements set forth herein shall be deemed a waiver as to any subsequent or similar breach or default. The failure of either Party to insist on the performance of any obligation hereunder shall not be deemed a waiver of any such obligation. No amendment, modification, waiver, release or discharge to this Agreement shall be binding upon the Parties unless in writing and duly executed by authorized representatives of both Parties.

17.10No Strict Construction. This Agreement has been prepared jointly and shall not be strictly construed against either Party.

In the event that any signature is delivered by facsimile transmission or by an e-mail which contains a portable document format (.pdf) file of an executed signature page, such executed signature page shall create a valid and binding obligation of the Party executing it (or on whose behalf such signature page is executed) with the same force and effect as if such executed signature page were an original thereof.

17.15Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable under any present or future law, and if the rights or obligations of a Party under this Agreement will not be materially and adversely affected thereby, (a) such provision shall be fully severable, (b) this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof, (c) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance here from and (d) in lieu of such illegal, invalid or unenforceable provision, the Parties shall negotiate in good faith a substitute legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as possible and as reasonably acceptable to the Parties.

17.16Performance by Affiliates. To the extent that this Agreement imposes obligations on Affiliates of a Party, such Party agrees to cause its Affiliates to perform such obligations. Subject to the terms of this Agreement, either Party may use one or more of its Affiliates to perform

its obligations and duties hereunder, provided that such Party so notifies the other Party in writing and provided further that such Party shall remain liable hereunder for the prompt payment and performance of all of its obligations hereunder.

17.17Further Assurance. Each Party shall duly execute and deliver, or cause to be duly executed and delivered, such further instruments and shall do and cause to be done such further acts and things, including the filing of any assignments, agreements, documents and instruments, as may be necessary or as the other Party may reasonably request in order to perfect any license, assignment or other transfer of any properties or rights under or pursuant to this Agreement.

17.18No Benefit to Third Parties. The representations, warranties and agreements set forth in this Agreement are for the sole benefit of the Parties and their successors and permitted assigns, and they shall not be construed as conferring any rights on any other parties.

Bristol-Myers Squibb and Nektar Therapeutics Announce Global Development & Commercialization Collaboration for Nektar’s CD122-biased Agonist, NKTR-214

(NEW YORK and SAN FRANCISCO, February 14, 2018) - Bristol-Myers Squibb Company (NYSE:BMY) and Nektar Therapeutics (Nasdaq: NKTR) announced today the companies have executed a global strategic development and commercialization collaboration for Nektar’s lead immuno-oncology program, NKTR-214. Under the collaboration, the companies will jointly develop and commercialize NKTR-214 in combination with Bristol-Myers Squibb’s Opdivo (nivolumab) and Opdivo plus Yervoy (ipilimumab) in more than 20 indications across 9 tumor types, as well as potential combinations with other anti-cancer agents from either of the respective companies and/or third parties.

NKTR-214, a CD122-biased agonist, is an investigational immuno-stimulatory therapy designed to selectively expand cancer-fighting T cells and natural killer (NK) cells directly in the tumor micro-environment and increase PD-1 expression on those immune cells.

“We are excited to bring our leading capabilities and expertise in developing cancer therapies together with Nektar’s innovative science to jointly develop and commercialize NKTR-214 in combination with Opdivo and Opdivo plus Yervoy,” said Giovanni Caforio, M.D., Chairman and CEO, Bristol-Myers Squibb. “Bristol-Myers Squibb has established Opdivo plus Yervoy as the only approved immunotherapy combination for cancer patients and built a robust oncology pipeline. With this commitment to development of NKTR-214, an investigational therapy designed with a unique approach to harnessing the full potential of the interleukin-2 pathway, we now have a third validated I-O mechanism that has demonstrated a clinical benefit in patients, and holds significant potential to expand the benefits that these immuno-oncology agents can bring to patients with cancer.”

Bristol-Myers Squibb and Nektar have agreed to a joint clinical development plan to evaluate NKTR-214 with Opdivo and Opdivo plus Yervoy in registration-enabling clinical trials in more than 20 indications in 9 tumor types including melanoma, renal cell carcinoma, non-small cell lung cancer, bladder and triple negative breast cancer. Pivotal studies in renal cell carcinoma and melanoma are expected to be initiated in mid-2018.

“Bristol-Myers Squibb, the global leader in immuno-oncology, is the ideal collaborator to enable us to establish NKTR-214 as a backbone immunotherapy in the treatment of cancer,” said Howard Robin, President & CEO of Nektar. "NKTR-214’s ability to grow tumor infiltrating lymphocytes (TILs) in vivo and replenish the immune system is critically important as many patients battling cancer lack sufficient TIL populations to benefit from approved checkpoint inhibitor therapies. This strategic collaboration allows us to very quickly develop NKTR-214 with the leading approved PD-1 immune checkpoint inhibitor in numerous registrational trials. We look forward to our continued relationship with Bristol-Myers Squibb as we work together to advance cancer treatment for patients around the world."

Under the terms of the agreement, Bristol-Myers Squibb will make an upfront cash payment of $1.0 billion and an equity investment of $850 million (8,284,600 shares of Nektar’s common stock at $102.60 per share). Bristol-Myers Squibb has agreed to certain lock-up, standstill and voting provisions on its share ownership for a period of five years subject to certain specified exceptions.

Nektar is also eligible to receive an additional $1.78 billion in milestones, of which $1.43 billion are development and regulatory milestones and the remainder are sales milestones. Nektar will book revenue for worldwide sales of NKTR-214 and the companies will split global profits for NKTR-214 with Nektar receiving 65% and Bristol-Myers Squibb 35%. Bristol-Myers Squibb will retain 100% of product revenues for its own medicines. The parties also will share development costs relative to their ownership interest of medicines included in the trials. For trials in the joint clinical development plan that include NKTR-214 with Opdivo only, the parties will share development costs with 67.5% allocated to Bristol-Myers Squibb and 32.5% allocated to Nektar. For trials in the joint clinical development plan that include NKTR-214 with Opdivo and Yervoy, the parties will share development costs with 78% allocated to Bristol-Myers Squibb and 22% allocated to Nektar.

Both Bristol-Myers Squibb and Nektar have agreed for a specified period of time to not commence development with overlapping mechanisms of action in the same indications as those included in the joint clinical development plan. The parties are otherwise free to develop NKTR-214 with their own pipeline assets and/or any other third party compounds. Both parties have agreed to initiate registration-enabling studies in the joint clinical development plan within 14 months of the effective date of the agreement, subject to allowable delays.

Both parties will jointly commercialize NKTR-214 on a global basis. Bristol-Myers Squibb will lead global commercialization activities for NKTR-214 combinations with Bristol-Myers Squibb medicines and Nektar will co-commercialize such combinations in the US, major EU markets and Japan. Nektar will lead global commercialization activities for NKTR-214 combinations with either Nektar medicines and/or other third-party medicines.

For Bristol-Myers Squibb, the transactions are expected to be dilutive in 2018 and 2019 to the company’s non-GAAP EPS by $0.05 and $0.20, respectively. Nektar and Bristol-Myers Squibb currently expect to complete the transaction during the second quarter of 2018, subject to the expiration or termination of applicable waiting periods under all applicable US antitrust laws and the satisfaction of other usual and customary closing conditions. Further details of the agreement can be found in Nektar’s Form 8-K filed today with the Securities and Exchange Commission. Sidley Austin LLP is acting as legal counsel to Nektar for the strategic

Nektar and Bristol-Myers Squibb entered into a clinical collaboration in September of 2016 to evaluate the potential for the combination of Opdivo and NKTR-214 to show improved and sustained efficacy and tolerability above the current standard of care. The Phase 1/2 PIVOT clinical study is ongoing in over 350 patients with melanoma, kidney, non-small cell lung cancer, bladder, and triple-negative breast cancers.

Nektar will host a conference call and webcast presentation today, February 14, 2018 at 8:00 a.m. Eastern Time to discuss the transaction. The call can be accessed by dialing (877) 881-2183 (U.S.) or (970) 315-0453 (international), and entering passcode 2289559. To access the live webcast, or the subsequent archived recording, visit the Investor Events section of the Nektar website at http://ir.nektar.com/events-and-presentations/events. The webcast will be available for replay on Nektar’s website for two weeks following the call.

NKTR-214 is an experimental therapy designed to stimulate cancer-killing immune cells in the body by targeting CD122 specific receptors found on the surface of these immune cells, known as CD8+ effector T cells and Natural Killer (NK) cells. Growing these tumor-infiltrating lymphocytes (TILs) in vivo and replenishing the immune system is critically important as many patients battling cancer lack sufficient TIL populations to benefit from approved checkpoint inhibitor therapies. In preclinical studies, treatment with NKTR-214 resulted in a rapid expansion of these cells and mobilization into the tumor micro-environment.^1,2 NKTR-214 has an antibody-like dosing regimen similar to the existing checkpoint inhibitor class of approved medicines.

At Bristol-Myers Squibb, patients are at the center of everything we do. Our vision for the future of cancer care is focused on researching and developing transformational Immuno-Oncology (I-O) medicines for hard-to-treat cancers that could potentially improve outcomes for these patients.

We are leading the scientific understanding of I-O through our extensive portfolio of investigational compounds and approved agents. Our differentiated clinical development program is studying broad patient populations across more than 50 types of cancers with 14 clinical-stage molecules designed to target different immune system pathways. Our deep expertise and innovative clinical trial designs position us to advance I-O/I-O, I-O/chemotherapy, I-O/targeted therapies and I-O radiation therapies across multiple tumors and potentially deliver the next wave of therapies with a sense of urgency. We also continue to pioneer research that will help facilitate a deeper understanding of the role of immune biomarkers and how patients’ tumor biology can be used as a guide for treatment decisions throughout their journey.

We understand making the promise of I-O a reality for the many patients who may benefit from these therapies requires not only innovation on our part but also close collaboration with leading experts in the field. Our partnerships with academia, government, advocacy and biotech companies support our collective goal of providing new treatment options to advance the standards of clinical practice.

Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.

Opdivo’s leading global development program is based on Bristol-Myers Squibb’s scientific expertise in the field of Immuno-Oncology and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has enrolled more than 25,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.

In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 60 countries, including the United States, the European Union and Japan. In October 2015, the company’s Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.

Yervoy is a recombinant, human monoclonal antibody that binds to the cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4). CTLA-4 is a negative regulator of T-cell activity. Yervoy binds to CTLA-4 and blocks the interaction of CTLA-4 with its ligands, CD80/CD86. Blockade of CTLA-4 has been shown to augment T-cell activation and proliferation, including the activation and proliferation of tumor infiltrating T-effector cells. Inhibition of CTLA-4 signaling can also reduce T-regulatory cell function, which may contribute to a general increase in T-cell responsiveness, including the anti-tumor immune response. On March 25, 2011, the U.S. Food and Drug Administration (FDA) approved Yervoy 3 mg/kg monotherapy for patients with unresectable or metastatic melanoma. Yervoy is approved for unresectable or metastatic melanoma in more than 50 countries. There is a broad, ongoing development program in place for Yervoy spanning multiple tumor types.

YERVOY can result in severe and fatal immune-mediated adverse reactions. These immune-mediated reactions may involve any organ system; however, the most common severe immune-mediated adverse reactions are enterocolitis, hepatitis, dermatitis (including toxic epidermal necrolysis), neuropathy, and endocrinopathy. The majority of these immune-mediated reactions initially manifested during treatment; however, a minority occurred weeks to months after discontinuation of YERVOY.

Assess patients for signs and symptoms of enterocolitis, dermatitis, neuropathy, and endocrinopathy and evaluate clinical chemistries including liver function tests (LFTs), adrenocorticotropic hormone (ACTH) level, and thyroid function tests at baseline and before each dose.

Permanently discontinue YERVOY and initiate systemic high-dose corticosteroid therapy for severe immune-mediated reactions.

Withhold for Grade 3 and permanently discontinue for Grade 4 rash. For symptoms or signs of SJS or TEN, withhold OPDIVO and refer the patient for specialized care for assessment and treatment; if confirmed, permanently discontinue. In patients receiving OPDIVO monotherapy, immune-mediated rash occurred in 9% (171/1994) of patients. In patients receiving OPDIVO with YERVOY, immune-mediated rash occurred in 22.6% (92/407) of patients.

In a separate Phase 3 study of YERVOY 3 mg/kg, severe, life-threatening, or fatal immune-mediated dermatitis (eg, Stevens-Johnson syndrome, toxic epidermal necrolysis, or rash complicated by full thickness dermal ulceration, or necrotic, bullous, or hemorrhagic manifestations; Grade 3-5) occurred in 13 (2.5%) patients. 1 (0.2%) patient died as a result of toxic epidermal necrolysis. 1 additional patient required hospitalization for severe dermatitis.

OPDIVO can cause immune-mediated encephalitis. Evaluation of patients with neurologic symptoms may include, but not be limited to, consultation with a neurologist, brain MRI, and lumbar puncture. Withhold OPDIVO in patients with new-onset moderate to severe neurologic signs or symptoms and evaluate to rule out other causes. If other etiologies are ruled out, administer corticosteroids and permanently discontinue OPDIVO for immune-mediated encephalitis. In patients receiving OPDIVO monotherapy, encephalitis occurred in 0.2% (3/1994) of patients. Fatal limbic encephalitis occurred in one patient after 7.2 months of exposure despite discontinuation of OPDIVO and administration of corticosteroids. Encephalitis occurred in one patient receiving OPDIVO with YERVOY (0.2%) after 1.7 months of exposure.

Based on the severity of the adverse reaction, permanently discontinue or withhold OPDIVO, administer high-dose corticosteroids, and, if appropriate, initiate hormone-replacement therapy.

Across clinical trials of OPDIVO monotherapy or in combination with YERVOY, the following clinically significant immune-mediated adverse reactions, some with fatal outcome, occurred in <1.0% of patients receiving OPDIVO: myocarditis, rhabdomyolysis, myositis, uveitis, iritis, pancreatitis, facial and abducens nerve paresis, demyelination, polymyalgia rheumatica, autoimmune neuropathy, Guillain-Barré syndrome, hypopituitarism, systemic inflammatory response syndrome, gastritis, duodenitis, sarcoidosis, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), motor dysfunction, vasculitis, and myasthenic syndrome.

OPDIVO can cause severe infusion reactions, which have been reported in <1.0% of patients in clinical trials. Discontinue OPDIVO in patients with Grade 3 or 4 infusion reactions. Interrupt or slow the rate of infusion in patients with Grade 1 or 2. In patients receiving OPDIVO monotherapy, infusion-related reactions occurred in 6.4% (127/1994) of patients. In patients receiving OPDIVO with YERVOY, infusion-related reactions occurred in 2.5% (10/407) of patients.

Complications, including fatal events, occurred in patients who received allogeneic HSCT after OPDIVO. Outcomes were evaluated in 17 patients from Checkmate 205 and 039, who underwent allogeneic HSCT after discontinuing OPDIVO (15 with reduced-intensity conditioning, 2 with myeloablative conditioning). Thirty-five percent (6/17) of patients died from complications of allogeneic HSCT after OPDIVO. Five deaths occurred in the setting of severe or refractory GVHD. Grade 3 or higher acute GVHD was reported in 29% (5/17) of patients. Hyperacute GVHD was reported in 20% (n=2) of patients. A steroid-requiring febrile syndrome, without an identified infectious cause, was reported in 35% (n=6) of patients. Two cases of encephalitis were reported: Grade 3 (n=1) lymphocytic encephalitis without an identified infectious cause, and Grade 3 (n=1) suspected viral encephalitis. Hepatic veno-occlusive disease (VOD) occurred in one patient, who received reduced-intensity conditioned allogeneic HSCT and died of GVHD and multi-organ failure. Other cases of hepatic VOD after reduced-intensity conditioned allogeneic HSCT have also been reported in patients with lymphoma who received a PD-1 receptor blocking antibody before transplantation. Cases of fatal hyperacute GVHD have also been reported. These complications may occur despite intervening therapy between PD-1 blockade and allogeneic HSCT.

Follow patients closely for early evidence of transplant-related complications such as hyperacute GVHD, severe (Grade 3 to 4) acute GVHD, steroid-requiring febrile syndrome, hepatic VOD, and other immune-mediated adverse reactions, and intervene promptly.

Based on their mechanisms of action, OPDIVO and YERVOY can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with an OPDIVO- or YERVOY- containing regimen and for at least 5 months after the last dose of OPDIVO.

It is not known whether OPDIVO or YERVOY is present in human milk. Because many drugs, including antibodies, are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from an OPDIVO-containing regimen, advise women to discontinue breastfeeding during treatment. Advise women to discontinue nursing during treatment with YERVOY and for 3 months following the final dose.

This press release contains "forward-looking statements" as that term is defined in the Private Securities Litigation Reform Act of 1995 regarding the research, development and commercialization of pharmaceutical products. Such forward-looking statements are based on current expectations and involve inherent risks and uncertainties, including factors that could delay, divert or change any of them, and could cause actual outcomes and results to differ materially from current expectations. No forward-looking statement can be guaranteed. Among other risks, there can be no guarantee that the collaboration with Nektar will progress as contemplated in this release or that NKTR-214, alone or in combination with Opdivo or Opdivo plus Yervoy will receive regulatory approval for the treatment of cancer. Forward-looking statements in this press release should be evaluated together with the many uncertainties that affect Bristol-Myers Squibb's business, particularly those identified in the cautionary factors discussion in Bristol-Myers Squibb's Annual Report on Form 10-K for the year ended December 31, 2017 in our Quarterly Reports on Form 10-Q and our Current Reports on Form 8-K. Bristol-Myers Squibb undertakes no obligation to publicly update any forward-looking statement, whether as a result of new information, future events or otherwise.

This press release contains forward-looking statements which can be identified by words such as: "anticipate," "intend," "plan," "expect," "believe," "should," "may," "will" and similar references to future periods. Examples of forward-looking statements include, among others, statements we make regarding the therapeutic potential of NKTR-214, the therapeutic potential of NKTR-214 in combination with OPDIVO, the development plans and timing related to NKTR-214, and the potential of our technology and drug candidates in our research and development pipeline. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Our actual results may differ materially from those indicated in the forward-looking statements. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause our actual results to differ materially from those indicated in the forward-looking statements include, among others: (i) our statements regarding the therapeutic potential of NKTR-214 in combination with Opdivo are based on findings and observations from ongoing clinical studies and these finding and observations will evolve over time as more data emerges from the studies; (ii) NKTR-214 is in early-stage clinical development and the risk of failure remains high and failure can unexpectedly occur due to efficacy, safety, economic, commercial or other unpredictable factors; (iii) the timing of the commencement or end of clinical trials and the availability of clinical data may be delayed or unsuccessful due to regulatory delays, slower than anticipated patient enrollment, manufacturing challenges, changing standards of care, evolving regulatory requirements, clinical trial design, clinical outcomes, competitive factors, or delay or failure in ultimately obtaining regulatory approval in one or more important markets; (iv) scientific discovery of new medical breakthroughs is an inherently uncertain process and the future success of applying our technology platform to potential new drug candidates (such as NKTR-214) is therefore highly uncertain and unpredictable and one or more research and development programs could fail; (v) patents may not issue from our patent applications for our drug candidates including NKTR-214, patents that have issued may not be enforceable, or additional intellectual property licenses from third parties may be required; and (vi) certain other important risks and uncertainties set forth in our Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on November 8, 2017. Any forward-looking statement made by us in this press release is based only on information currently available to us and speaks only as of the date on which it is made. We undertake no obligation to update any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise.
