Nektar shall receive [***] of Net Sales and Net Sublicense Revenues and bear [***] of Allowable Expenses, or (y) in the event that Nektar opts out of sharing Product Profit and Loss under Section 8.2(b)(i), then after such
time as Nektar has opted out of sharing Product Profit and Loss pursuant to Section 8.2(b)(ii), the royalty rate on royalties due under Section 8.2(b)(ii) shall be [***]. Notwithstanding the foregoing, [***], then this
Section 8.2(b)(iii) shall apply again. Exhibit 8.2(b)(iii) contains an example of the Product Profit and Loss calculation methodology under Section 8.2(b)(iii)(x). 
 (c) [***] Expenses. 
 (i) The
expenses Nektar shall be entitled to include in Allowable Expenses in the calculation of Product Profit and Loss for payments [***] with respect to the Shared Territory shall not exceed [***] of Net Sales of the Product in the Shared

of all other amounts [***] with respect to the Shared Territory, including, without limitation, payments resulting from “[***], and such amounts shall not be included in Allowable Expenses. 
 (ii) [***]. 
 (d) Method and
Timing of Payments. Within [***] days after the end of each of the [***] calendar quarters, and [***] days after the end of the [***] calendar quarter, of each calendar year following Commercial Launch in the Shared

offer to sell or sell the Product, such sublicenses shall require the Sublicensee to account for and report its Net Sales of the Product on the same basis as if such sales were Net Sales of the Product by Bayer, and Bayer shall pay royalties on such
sales as if the Net Sales of the Sublicensees were Net Sales of Bayer. 
 8.9 Accounting. 
 (a) For the purposes of determining all costs and expenses hereunder, any cost or expense allocated by either Party to a particular category for
the Product shall not also be allocated to another category for such Product, and any cost or expense allocated to the Product in a particular country shall not be allocated or allocable to another product of such Party in such country or the same
Product in a different country. 
 (b) Each Party agrees to determine Net Sales, Allowable Expenses, Patent costs, Trademark Expenses
and Pre-Launch Costs with respect to the Product using its standard accounting procedures, consistent with GAAP or IFRS or IAS to the extent practical as if the Product was a solely owned product of each Party, except as specifically provided in
this Agreement. In the case of amounts to be determined by Third Parties (for example, Net Sales by Sublicensees), such amounts shall be determined in accordance with GAAP or IFRS or IAS in effect in the country in which such Third Party is engaged.
The Parties also recognize that such

and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions. 
  
 
procedures may change from time to time and that any such changes may affect the definition of Net Sales, Allowable Expenses, or Pre-Launch Costs. The
Parties agree that, where such changes are economically material to either Party, adjustments shall be made to compensate the affected Party in order to preserve the same economics as are reflected under this Agreement under such Party’s
accounting procedures in effect prior to such change (for example, Development or Commercialization). Where the change is or would be material to one Party, the other Party shall provide an explanation of the proposed change and an accounting of the
effect of the change on the relevant revenue, cost, or expense category. 
 (c) In the event of the payment or receipt of non-cash
consideration in connection with the performance of activities under this Agreement, the Party engaging in such non-cash transaction shall advise the JFC of such transaction, including without limitation such Party’s assessment of the fair
market value of such non-cash consideration and the basis therefor. Such transaction shall be accounted for on a cash equivalent basis, as mutually agreed by the Parties in good faith.

amount otherwise payable such amounts to the extent it is required to deduct and withhold with respect to such payment under any provision of federal, state, local or foreign tax law. Such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the Party on whose behalf it was withheld. No deduction shall be made to the extent the paying Party is timely furnished with necessary documents certifying that the payment is exempt from tax or subject to a reduced
tax rate.

 15. CONFIDENTIALITY 
 15.1 Confidentiality; Exceptions. For the
term of this Agreement and for a period of [***] years thereafter, each Party shall maintain in confidence all Information and materials of the other Party disclosed or provided to it by the other Party (either pursuant to this Agreement, or
the Confidential Disclosure Agreement entered into by Nektar and Bayer Pharmaceuticals Corporation dated [***] (the “Confidential Disclosure Agreement”)), to the extent related to Amikacin, and identified as confidential,
either in writing or verbally (provided any verbally disclosed Information is reduced to writing and submitted to the other Party within thirty (30) days of such verbal disclosure) (together with all embodiments thereof, the
“Confidential Information”). Confidential Information also includes, but is not limited to, Information generated hereunder, and Information regarding intellectual property and confidential or proprietary Information of Third
Parties. In addition, and notwithstanding the foregoing, if under Article 11 Information constituting inventions and discoveries are to be owned by one Party, such Information shall be deemed to be Confidential Information of such Party, even if
such Information is initially generated and disclosed by the other Party. The terms and conditions of this Agreement and the Confidential Disclosure Agreement also shall be deemed Confidential Information of both Parties. Notwithstanding the
foregoing, Confidential Information shall not include that portion of Information or materials that the receiving Party can demonstrate by contemporaneous written records was (i) known to the general public at the time of its disclosure to the

Party. 
 15.2 Degree of Care; Permitted Use. Each Party shall take reasonable steps to maintain the confidentiality of the
Confidential Information of the other Party, which steps shall be no less protective than those steps that such Party takes to protect its own Information and materials of a similar nature, but in no event less than a reasonable degree of care.
Neither Party shall use or permit the use of any Confidential Information of the other Party except for the purposes of carrying out its obligations or exercising its rights under this Agreement or the Confidential Disclosure Agreement, and neither
Party shall copy any Confidential Information of the other Party except as may be reasonably useful or necessary for such purposes. All Confidential Information of a Party, including without limitation all copies and derivations thereof, is and
shall remain the sole and exclusive property of the disclosing Party and subject to the restrictions provided for herein. Neither Party shall disclose any Confidential Information of the other Party other than to those of its directors, officers,
Affiliates, employees, licensors, independent contractors, Sublicensees, assignees, agents and external advisors directly concerned with the carrying out of this Agreement, on a strictly applied “need to know” basis; provided, however,
that such directors, officers, Affiliates, employees, licensors, independent contractors, Sublicensees, assignees, agents and external advisors are subject to confidentiality and non-use obligations at least as stringent as the confidentiality and
non-use obligations provided for in this Article 15. Except to the extent expressly permitted under this Agreement, the receiving Party may not use Confidential Information of the other Party in applying for Patents or securing other intellectual
property rights without first consulting with, and obtaining the written approval of, the other Party (which approval shall not be unreasonably withheld or delayed).

Information to a Patent office for the purposes of filing a Patent Application as permitted in this Agreement, or (f) the exercise by each Party of its rights granted to it under this Agreement or its retained rights, including, without
limitation, the Exploitation of the Product, and such Third Party agrees to confidentiality and non-use obligations at least as stringent as those specified for in this Article 15; provided that the receiving Party shall provide prior written notice
thereof to the disclosing Party and sufficient opportunity for the disclosing Party to review and comment on such required disclosure and request confidential treatment thereof or a protective order therefor.

 15.4 Irreparable Injury. The Parties acknowledge that either Party’s breach of this Article 15 would cause the other Party irreparable injury
for which it would not have an adequate remedy at law. In the event of a breach, the nonbreaching Party may seek injunctive relief, whether preliminary or permanent, in addition to any other remedies it may have at law or in equity, without
necessity of posting a bond. 
 15.5 Return of Confidential Information. Each Party shall return or destroy, at the other Party’s

 16. PUBLICITY

 16.1 Public Disclosure. The Parties agree that the initial public announcement of the execution of this Agreement shall be in the
form of a mutually agreed upon press release that describes the nature and scope of the collaboration including its aggregate value (the “Initial Public Disclosure”). In connection with the issuance of such press release, Nektar
shall also be permitted to make any filings required under Applicable Law, including without limitation filings with the U.S. Securities and Exchange Commission to report the execution of this Agreement. During the term of this Agreement, in all
cases other than the announcement set forth in the Initial Public Disclosure, each Party shall submit to the other Party (the “Non-Publishing Party”) for review and approval all proposed press releases, academic, scientific and
medical publications and public presentations relating to the Product that have not been previously disclosed. Such review and approval shall be conducted for the purposes of preserving intellectual property protection and determining whether any
portion of the proposed publication or presentation containing the Confidential Information of the Non-Publishing Party should be modified or deleted, and (in the case of a disclosure that Nektar wishes to make) to determine whether such disclosure
is in the best interests of the Parties in connection with the Development of the Product (such determination to be made in Bayer’s reasonable discretion). Written copies of such proposed publications and presentations (other than press
releases) shall be submitted to the Non-Publishing Party no later than [***] days before submission for publication or presentation; provided that, for general disclosure of program status to investors or analysts, or in public conference or
earnings calls (“General Disclosure”) such [***] day period shall be shortened to [***] business days. Subject to Applicable Law, written copies of proposed press releases shall be submitted to the Non-Publishing Party
no later than [***] hours before release. The Non-Publishing Party shall provide its comments, if any, and (if it so chooses) its approval within (a) [***] business days, in the case of a press release, and (b) [***]
business days of its receipt of any other written copy. With respect to matters other than press releases, the review period may be extended for an additional [***] days, or for General Disclosures [***] business days, in the event
the Non-Publishing Party can demonstrate reasonable need for such extension, including, without limitation, the preparation and filing of Patent Applications. This period may be further extended by mutual written agreement of the Parties. Nektar and
Bayer will each comply with standard academic practice regarding authorship of scientific publications and recognition of contribution of other parties in any publications.

successful, will effect such a remedy. If such alleged breach is not remedied in the time period set forth above, the nonbreaching Party shall be entitled, without prejudice to any of its other rights conferred on it by this Agreement, and in
addition to any other remedies available to it by law or in equity, to terminate this Agreement upon written notice to the other Party. In the event of a dispute regarding any payments due and owing hereunder, all undisputed amounts shall be paid

 (a) The license
grants in Section 2.1 shall terminate and all rights with respect thereto shall revert in their entirety to Nektar. 
 (b)
Unless such termination was by Bayer under Section 18.2(b)(ii) or by Nektar under Section 18.3, subject to any Third Party (excluding Agents of Bayer) rights existing at the time of termination and to the extent that technology covered
by a Patent Controlled by Bayer or its Affiliates or an Agent of Bayer is incorporated into or is otherwise used in connection with the Product by Bayer during the Development or Commercialization of the Product pursuant to this Agreement, Bayer
agrees that neither it nor its Agents will, and Bayer shall cause its Affiliates not to, assert against Nektar, its subsidiaries, Affiliates or sublicensees, any claim, or institute any action or proceeding, whether at law or equity, under any

exporting, having exported or marketing the Product as it exists as of the termination date. This covenant shall be binding upon, and inure to the benefit
of, the Parties, their successors, and assigns. Nektar’s sublicensees for the Product shall be Third Party beneficiaries of this Section 18.6(b). 
 (c) Bayer shall, without additional consideration, assign to Nektar all of Bayer’s right, title and interest in and to (i) the continuation Patent Application [***], and (ii) any Patents

costs or recovery, as applicable, and Nektar shall bear or receive [***] of such costs or recovery, as applicable. If one Party chooses not to participate in enforcement of the Joint Patent Rights, the other Party shall have the right to
enforce such Patents (provided all of the costs and expenses of both Parties incurred in connection with such enforcement shall be borne by the enforcing Party), including without limitation the right to settle such litigation (subject to the next
sentence of this Section 18.6(f)) at its sole expense and to keep all recoveries associated therewith. The joint consent of Bayer and Nektar (which consent shall not be unreasonably withheld or delayed) shall be required of any settlement,
consent judgment or other voluntary final disposition of a suit under this Section 18.6(f) that could adversely affect the other Party’s interest. If, in any enforcement action taken pursuant to this Section 18.6(f), the enforcing
Party determines that the other Party is an indispensable party to such action, the other Party hereby consents to be joined in such action and, in such event, the other Party shall have the right to be represented in such action using counsel of

 (g) Unless such termination was by Bayer under Section 18.2(b)(ii) or by Nektar under Section 18.3, to the extent they are assignable,

 (h) Nektar shall supply Bayer’s or its designee’s requirements of the Device at commercially reasonable prices until the earlier of
Bayer’s qualification of alternate supply sources, or [***] months after termination. 
 (i) Bayer shall continue to pay
royalties in the Royalty Territory in accordance with Section 8.4(a), (b), (c), (e) and (f) and Sections 8.5-8.10 provided that Bayer shall not be required to make any additional royalty payments under Section 8.4(d). However,
Bayer shall continue to pay Milestone Payments under Section 8.3. In addition, Bayer may either: 
 (x) treat the Shared
Territory as the Royalty Territory for purposes of the payments to be made under Section 8.4(a), (b), (c), (e) and (f) and Sections 8.5-8.10 (but not for purposes of Section 8.4(d)), provided that the Net Sales in the Shared
Territory shall not be aggregated with Net Sales in the Royalty Territory for purposes of payments to be made under Section 8.4(a), in which case Bayer shall be deemed to have elected its remedy for such breach by Nektar and shall not have the
right to pursue other remedies available to it under law or in equity in connection with such breach, or 
 (y) treat the Shared
Territory as the Royalty Territory for purposes of the payments to be made under Section 8.4(a), (b), (c), (e) and (f) and Sections 8.5-8.10 (but not for purposes of Section 8.4(d)), provided that the Net Sales in the Shared

 In the case that either clause (x) or (y) of this Section 18.7(i) applies: (A) Nektar would thereafter no longer be obligated to bear any portion of
Allowable Expenses and would not be entitled to participate in Product Profit and Loss under Section 8.2(b)(i), (B) Nektar, after the effective date of such termination, shall be solely responsible for the payment of all amounts
[***] with respect to the Territory, and (C) all of the Parties’ payment obligations, other than those relating to Product Profit and Loss and Allowable Expenses, as set forth in this Agreement will continue to apply. For clarity,

 (k) Surviving Rights. Except where expressly provided for otherwise in this Agreement, termination of this Agreement pursuant to Section 18.4
for Nektar’s breach shall not relieve the Parties of any liability, including without limitation any obligation to make payments hereunder, which accrued hereunder prior to the effective date of such termination, nor preclude any Party from
pursuing all rights and remedies it may have hereunder or at law or in equity with respect to any breach of this Agreement, nor prejudice any Party’s right to obtain performance of any obligation. In the event of such termination, the following
provisions shall survive in addition to others specified in this Agreement to survive in such event: Sections 2.1–2.5 (subject to Sections 18.7(b) and (c)), 5.2(c), 5.8, 8.3, 8.4(a)–(c) and 8.4(e) and (f), 8.5-8.10, 11.3(a) (subject to

 18.8 General Surviving Obligations. The rights and obligations
set forth in this Agreement shall extend beyond the expiration or termination of the Agreement only to the extent expressly provided for herein, or to the extent that the survival of such rights or obligations are necessary to permit their complete
fulfillment or discharge. Without limiting the foregoing, the Parties have identified various rights and obligations which are understood to survive, as follows. In the event of expiration or termination of this Agreement for any reason, the
following provisions shall survive in addition to others specified in this Agreement to survive in such event. Termination of this Agreement shall not terminate Bayer’s obligation to pay all Milestone Payments, royalties and other payments
which shall have accrued hereunder (including without limitation any Milestone Payments then accrued because the event has occurred but the Milestone Payment is not yet due). Additionally, the rights and obligations of the Parties under Sections
10.2–10.3 (for the period set forth in Section 10.4), 11.1 (first sentence only), 11.2 (subject to Sections 18.6 and 18.7), 13.1 (for the period set forth therein), 14.1–14.3, 14.4 (for the period set forth therein), and Articles 1,

termination or expiration of this Agreement. 
 18.9 Challenge.  
 (a) Nektar shall have the right to terminate this Agreement immediately upon written notice if Bayer or its Affiliate challenges in a court of
competent jurisdiction, the validity, scope or enforceability of, or otherwise opposes, any Patent included in the Nektar Patent Rights, [***]. If a Sublicensee of Bayer or its Affiliate challenges the validity, scope or enforceability of or
otherwise opposes any Patent included in the Nektar Patent Rights under which such Sublicensee is sublicensed, then Bayer or its Affiliate, as applicable, shall, upon written notice from Nektar, terminate such sublicense. Bayer and its Affiliates
shall include provisions in all agreements under which a Third Party obtains a license under any Patent included in the Nektar Patent Rights providing that, if the Sublicensee challenges the validity or enforceability of or otherwise opposes any
such Patent under which the Sublicensee is sublicensed, then Bayer may terminate such sublicense agreement with such Sublicensee, and Bayer shall, upon request by Nektar, enforce such right if such Sublicensee breaches such restriction.

 (b) Bayer shall have the right to terminate this Agreement immediately upon written notice if Nektar or its Affiliate challenges in a court of
competent jurisdiction, the validity, scope or enforceability of or otherwise opposes any Patent licensed to Nektar under Section 11.2(a)(ii). If a Sublicensee of Nektar or its Affiliate challenges the validity, scope or enforceability of, or
otherwise opposes, any Patent licensed to Nektar under Section 11.2(a)(ii) under which such Sublicensee is sublicensed, then Nektar or its Affiliate, as applicable, shall, upon written notice from Bayer, terminate such sublicense. Nektar and
its Affiliates shall include provisions in all agreements under which a Third Party obtains a license under any Patent licensed to Nektar under Section 11.2(a)(ii) providing that if the sublicensee challenges the validity or enforceability of
or otherwise oppose any such Patent under which the sublicensee is sublicensed, Nektar or its Affiliate, as applicable, may terminate its sublicense agreement with such sublicensee, and Nektar shall, upon request by Bayer, enforce such right if such
sublicensee breaches such restriction. 
 18.10 Accrued Rights, Surviving Obligations. Termination or expiration of this Agreement
shall not relieve either Party from obligations that are expressly indicated to survive termination or expiration of the Agreement. Except as otherwise provided for in this Agreement, termination by a Party shall not be an exclusive remedy, and all
other remedies will be available to the terminating Party, in equity and at law. 
 18.11 Rights in Bankruptcy. All rights and
licenses granted under or pursuant to this Agreement by Nektar or Bayer are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the United States Bankruptcy Code, licenses of right to “intellectual property” as
defined under Section 101 of the United States Bankruptcy Code. The 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 United States
Bankruptcy Code. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against either Party under the United States Bankruptcy Code, the Party that is not a party to such proceeding shall be entitled to a
complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property, which, if not already in the non-subject Party’s possession, shall be promptly delivered to it
(a) upon any such commencement of a bankruptcy proceeding upon the non-subject Party’s written request therefor, unless the Party subject to such proceeding elects to continue to perform all of its obligations under this Agreement or
(b) if not delivered under clause (a) above, following the rejection of this Agreement by or on behalf of the Party subject to such proceeding upon written request therefor by the non-subject Party.

IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND FREEDOM FROM INFRINGEMENT OF THIRD PARTY RIGHTS. 
 20.
MISCELLANEOUS 
 20.1 Agency. Neither Party is, nor shall be deemed to be, an employee, agent,
co-venturer or legal representative of the other Party for any purpose. Neither Party shall be entitled to enter into any contracts in the name of, or on behalf of the other Party, nor shall either Party be entitled to pledge the credit of the other
Party in any way or hold itself out as having the authority to do so. 
 20.2 Assignment; Change of Control. 
 (a) Except as otherwise provided in this Agreement, neither this Agreement nor any interest hereunder shall be assignable by any Party without the
prior written consent of the other Party (which consent shall not be unreasonably withheld or delayed following the conclusion of the Project); provided, however, (i) the assignment of this Agreement by operation of law pursuant to a merger or
consolidation of either Party with or into any Third Party shall, regardless of the identity of the surviving entity to such merger or consolidation, not be deemed an assignment in violation of this Section 20.2, (ii) either Party, without
such consent, may assign its rights and delegate its duties hereunder to an Affiliate thereof without obtaining such consent, provided that the assigning Party agrees to remain primarily (and not secondarily or derivatively) liable for the full and
timely performance by such Affiliate of all its obligations hereunder, and (iii) either Party, without such consent, may assign its rights and delegate its duties hereunder to a successor entity or acquirer, provided that the assigning Party
agrees to remain primarily (and not secondarily or derivatively) liable for the full and timely performance by such assignee of all its obligations hereunder. 
 (b) If Nektar undergoes a Change of Control, Bayer shall have the right, exercisable within [***] days of its receipt of notice from Nektar of such Change of Control to do any or all of the following,
(i) to terminate Nektar’s co-promotion rights under Section 7.3, 7.4 and 7.8, (ii) to treat the Shared Territory as the Royalty Territory for purposes of the payments to be made under Section 8.4(a), (b), (c), (e) and
(f) and Sections 8.5-8.10 (but not for purposes of Section 8.4(d)) under this Agreement, provided that the Net Sales in the Shared Territory shall not be aggregated with Net Sales in the Royalty Territory for purposes of payments to made
under Section 8.4(a)), and further provided that the royalty rate applicable to the Shared Territory under Section 8.4(a) shall be fixed at [***] of annual Net Sales in the

Shared Territory [***] (a “Royalty Conversion”), and/or (iii) to terminate Nektar’s participation in the GPT, GBT, and RBU
in which case the Parties shall form new committees to govern the Commercialization and Development, respectively, of the Product, each of which committees has equal representation by each of Bayer and Nektar and which shall operate as set forth in
Sections 3.4(c), 3.5(c), and 3.6(c), respectively, with such newly formed committees having the responsibilities formerly held by the GPT, GBT, and RBU, respectively. If Bayer elects a Royalty Conversion, Nektar would thereafter no longer be
obligated to bear any portion of Allowable Expenses and would not be entitled to participate in Product Profit and Loss under Section 8.2(b)(i). In such event, (A) Nektar shall thereafter be solely responsible for the payment of all
amounts [***] with respect to the Territory, and (B) all of the Parties’ payment obligations, other than those relating to Product Profit and Loss and Allowable Expenses, as set forth in this Agreement will continue to apply. For
clarity, milestone payments payable to Nektar pursuant to Section 8.4(d) shall not accrue based on sales in the Shared Territory. 
 (c) This Agreement shall be binding upon and inure to the successors and permitted assignees of the Parties and the name of a Party appearing herein shall be deemed to include the names of such Party’s successor’s and
permitted assigns to the extent necessary to carry out the intent of this Agreement. Any assignment not in accordance with this Section 20.2 shall be void. 
 20.3 Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and
intent of this Agreement. 
 20.4 Force Majeure. Neither Party shall be liable or responsible to the other Party for loss or damages,
nor shall it have any right to terminate this Agreement for any default or delay attributable to any event beyond its reasonable control and without its fault or negligence, including but not limited to acts of God, acts of government (including
injunctions), fire, flood, earthquake, strike, lockout, labor dispute, breakdown of plant, shortage of critical equipment, loss or unavailability of manufacturing facilities or material, casualty or accident, civil commotion, acts of public enemies,
acts or terrorism or threat of terrorist acts, blockage or embargo and the like (a “Force Majeure Event”); provided, however, that in each such case the Party affected shall use reasonable efforts to avoid such occurrence and to
remedy it promptly. The Party affected shall give prompt notice of any such cause to the other Party. The Party giving such notice shall thereupon be excused from such of its obligations hereunder as it is thereby disabled from performing for so
long as it is so disabled and for [***] days thereafter and the Party receiving notice shall be similarly excused from its respective obligations which it is thereby disabled from performing; provided, however, that such affected Party
commences and continues to take reasonable and diligent actions to cure such cause. Notwithstanding the foregoing, nothing in this Section 20.4 shall excuse or suspend the obligation to make any payment due hereunder in the manner and at the
time provided. 
 20.5 Notices. All notices and other communications hereunder shall be in writing and shall be deemed given if
delivered personally or by facsimile transmission (receipt verified), telexed, mailed by registered or certified mail (return receipt requested), postage prepaid, or sent by express courier service, to the Parties at the following addresses (or at
such other address for a Party as shall be specified by like notice; provided that notices of a change of address shall be effective only upon receipt thereof):
