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.

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.

(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):
