(b)      Defense.   If both Parties are charged with infringement pursuant to a claim described in Section 6.4(a), the Parties shall defend such claim jointly, unless they agree otherwise.  If only one Party is charged with infringement, such Party will have the first right but not the obligation to defend such claim.  If the charged Party does not commence actions to defend such claim within [***] ([***]) calendar days after being so charged, then the other Party shall have the right, but not the obligation, to defend any such claim.  In any event, the non-defending Party shall reasonably cooperate with the Party conducting the defense of the claim and shall have the right to participate with separate counsel at its own expense, and the defending Party shall consider comments by the non-defending Party in good faith.  The Party defending the claim shall bear the cost and expenses of the defense of any such Third Party infringement claim and shall have sole rights to any recovery.  If the Parties jointly defend the claim, BioXcel shall bear [***] percent ([***]%), and Nektar shall bear [***] percent ([***]%) of any costs and expenses of the defense of any such Third Party infringement claim; provided, however, that, notwithstanding the foregoing, if the claim relates solely to one Party’s Compound, such Party will bear one hundred percent (100%) of the costs and expenses of the defense of such claim, shall have sole rights to any recovery and shall have the sole right, but not the obligation, to defend, settle and otherwise handle the disposition of such claim.  If either Party recovers monetary damages from any Third Party while jointly defending the claim, such recovery shall be allocated first to the reimbursement of any actual, unreimbursed costs and expenses incurred by the Parties in such litigation (including, for this purpose, a reasonable allocation of expenses of internal counsel) pro rata in accordance with the aggregate amounts spent by both Parties, and any remaining amounts shall be split [***] percent ([***]%) to BioXcel and [***] percent ([***]%) to Nektar, unless the Parties agree in writing to a different allocation.  Neither Party shall enter into any settlement concerning activities under this Agreement or the Combined Therapy that affects the other Party’s rights under this Agreement or imposes any obligations on the other Party, including any admissions of wrongdoing on behalf of the other Party, without such other Party’s prior written consent, not to be unreasonably withheld or delayed, except that a Party may settle any claim that solely relates to its Compound without the consent of the other Party as long as such other Party’s rights under this Agreement are not adversely impacted (in which case, it will obtain such other Party’s prior written consent, not to be unreasonably withheld or delayed).

6.5       Combined Therapy Trial Regulatory Documentation.   Subject to the license and other rights granted by each Party to the other Party pursuant to this Agreement, BioXcel and Nektar shall jointly own all right, title and interest in and to the Combined Therapy Trial Regulatory Documentation; provided, however, that Nektar shall retain sole and exclusive ownership of any Nektar Regulatory Documentation provided to BioXcel under this Agreement that is submitted with or referenced in the Combined Therapy Trial Regulatory Documentation and that BioXcel shall retain sole and exclusive ownership of any BioXcel Regulatory Documentation that is submitted with or referenced in the Combined Therapy Trial Regulatory Documentation.  This Section 6.5 is without limitation of any other disclosure obligations under this Agreement.

9.5       Press Releases and Publications.

(a)      The Parties shall jointly agree to the content and timing of all external communications with respect to this Agreement (including an initial press release, the content of which shall be as attached hereto as Exhibit B, subsequent press releases, Q&As, and the content and wording of any listing any Combined Therapy Trial required to be listed on a public database or other public registry such as www.clinicaltrials.gov).  For clarity, if either Party terminates this Agreement pursuant to Section 12.4, the Parties shall mutually agree upon any external communication related to such termination, which shall not include the rationale for such termination unless (and to the extent) mutually agreed by the Parties.  Notwithstanding any provision of this Agreement to the contrary, each Party shall be permitted to publicly disclose information that such Party 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)      BioXcel and Nektar agree to collaborate to publicly disclose, publish or present (1) top-line results from each Combined Therapy Trial, 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 (2) the conclusions and outcomes (the “Results”) of each Combined Therapy Trial at a scientific conference as soon as reasonably practicable following the completion of such Combined Therapy Trial, subject in the case of (2) 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 (i) any abstract or press release at least [***] ([***]) Business Days before submission to a Third Party and (ii) any proposed slide presentation, publication, poster presentation or any other disclosure, publication or presentation at least [***] ([***]) Business Days 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 BioXcel Study Invention (solely with respect to BioXcel) or Nektar Study Invention (solely with respect to Nektar) or Combined Therapy Trial Invention disclosed therein.  If practicable, the disclosure, publication or presentation shall be delayed for an additional [***] ([***]) Business Days 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 Executive Officers (or their respective designees); provided that, in the absence of agreement after such good faith discussions, and upon expiration of the additional [***] ([***]) Business Days (to the extent provided pursuant to the above), (A) academic collaborators engaged by BioXcel in connection with the performance of the Combined Therapy Trials may publish

Combined Therapy Study Data obtained by such academic collaborator solely to the extent that such ability to publish such Combined Therapy Study Data is set forth in an agreement between BioXcel and such academic collaborator relating to the conduct of Combined Therapy Trials and (B) 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 Combined Therapy Trial).  Notwithstanding the foregoing, BioXcel hereby authorizes disclosure to BMS in accordance with Section 9.4 above.  Notwithstanding the foregoing, nothing herein shall prevent or restrict BMS from making any disclosures of published Study Data disclosed to it by Nektar pursuant to Section  9.4 or of the existence of this Agreement, in each case in order for BMS 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.

9.6       Destruction of Confidential Information.   Upon expiration or termination of the Agreement, the Receiving Party shall, upon request by the Disclosing Party, immediately destroy or return all of the Disclosing Party’s Confidential Information relating solely to its Compound as monotherapy (but not to the Combined Therapy or the Combined Therapy Study Data) in its possession; provided, however, that the Receiving Party shall be entitled to retain one (1) copy of Confidential Information solely for record-keeping purposes and shall not be required to destroy any off-site computer files created during automatic system back up which are subsequently stored securely by the Receiving Party.

12.7     Termination by Either Party if no CPI Compound Agreed.  Either Party shall have the right to terminate this Agreement on at least [***] ([***]) days notice to the other Party in the event the Parties have not agreed in writing on the terms for obtaining a CPI Compound by November 30, 2018, or such later date as may be mutually agreed by the Parties in writing.

long as the condition constituting force majeure continues and the nonperforming Party takes reasonable efforts to remove the condition.  For purposes of this Agreement, force majeure shall mean acts of God, strikes or other concerted acts of workers (except for strikes or other concerted acts of a Party’s respective workers), civil disturbances, fires, earthquakes, acts of terrorism, floods, explosions, riots, war, rebellion, sabotage or failure or default of public utilities or common carriers or similar conditions beyond the control of the Parties.

13.6     Notices.   Any notice required or permitted to be given under this Agreement shall be in writing, shall specifically refer to this Agreement and shall be deemed to have been sufficiently given for all purposes if such notice is timely and is:(a) mailed by first class certified or registered mail, postage prepaid, return receipt requested, (b) sent by express delivery service, or (c) personally delivered.  Unless otherwise specified in writing, the mailing addresses of the Parties shall be as described below.

Any such communication shall be deemed to have been received when delivered.  It is understood and agreed that this Section 13.6 is not intended to govern the day-to-day business communications necessary between the Parties in performing their duties, in due course, under the terms of this Agreement.

13.7     No Waiver; Modifications.   It is agreed that no waiver by a Party hereto of any breach or default of any of the covenants or agreements herein set forth shall be deemed a waiver as to any subsequent and/or similar breach or default.  The failure of either Party to insist on the performance of any obligation hereunder shall not be deemed to be a waiver of any such obligation.  No amendment, modification, release or discharge to this Agreement, the Quality Agreement or any material amendment, modification, release or discharge to a Bioanalysis Plan, a Statistical Analysis Plan, or a CRO Agreement (to the extent provided in Section 2.4(o)) shall be binding upon the Parties unless in writing and duly executed by authorized representatives of both Parties.

13.8     No Strict Construction.   This Agreement has been prepared jointly and shall not be strictly construed against either Party.  No presumption as to construction of this Agreement shall apply against either Party with respect to any ambiguity in the wording of any provision(s) of this Agreement irrespective of which Party may be deemed to have authored the ambiguous provision(s).

13.9     Independent Contractor; No BioXcel Third Party Beneficiary Rights.   The Parties are independent contractors of each other, and the relationship between the Parties shall not constitute a partnership, joint venture or agency.  Neither Party shall be the agent of the other or have any authority to act for, or on behalf of, the other Party in any matter. BioXcel shall not be a third party beneficiary under any agreement between Nektar and BMS, including without limitation the SCA.

13.10   Assignment; Licensees.

(a)      Assignment.   Neither Party may assign or transfer this Agreement or any rights or obligations hereunder without the prior written consent of the other Party, except that a Party may make such an assignment without the other Party’s consent, provided that such Party provide written notice of such assignment to the other Party within thirty (30) calendar days of such assignment, (a) to an Affiliate, (b) to a Third Party that merges with, consolidates with or acquires substantially all of the assets or voting control of the assigning Party or (c) to a Third Party that acquires all the rights to the BioXcel Compound, in the case of BioXcel, or the Nektar Compound, in the case of Nektar. Any assignment or attempted assignment by any Party in violation of the terms of this Section 13.10 shall be null and void and of no legal effect.

(b)      Licensees.   If a Party grants its or the other Party’s Affiliate or a Third Party a license (other than a license solely to make a Product for a Party) to develop and commercialize its Single Agent Compound on a worldwide basis or in any geographic region and/or for all purposes or a limited field, (a “Licensee”), such Party will obtain the Licensee’s agreement to abide by the terms of this Agreement in the same manner as the licensor Party.

13.11   Headings.   The captions to the several Sections and Articles hereof are not a part of this Agreement, but are included merely for convenience of reference only and shall not affect its meaning or interpretation.

13.12   Counterparts.   This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one (1) and the same instrument.  This Agreement may be executed by facsimile or electronic (e.g., .pdf) signatures and such signatures shall be deemed to bind each Party hereto as if they were original signatures.

13.13   Severability.    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 herefrom and (d) in lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as a part of this Agreement a legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible and reasonably acceptable to the Parties.

13.14   Further Assurance.   Each Party shall duly execute and deliver, or cause to be duly executed and delivered, such further instruments and do and cause to be done such further acts and things, including the filing of such 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 or any properties or rights under, or pursuant, to this Agreement.

13.15   No 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.

13.16   Construction.

(a)      General.   Except as otherwise explicitly specified to the contrary, (a) references to a Section, Article or Exhibit means a Section or Article of, or Exhibit to, this Agreement and all subsections thereof, unless another agreement is specified; (b) references to a particular statute or regulation include all rules and regulations promulgated thereunder and any successor statute, rules or regulations then in effect, in each case including the then-current amendments thereto; (c) words in the singular or plural form include the plural and singular form, respectively; (d) the terms “including,” “include(s),” “such as,” and “for example” used in this Agreement mean including the generality of any description preceding such term and will be deemed to be followed by “without limitation”; and (e) the words “hereof,” “herein,” “hereunder,” “hereby” and derivative or similar words refer to this Agreement.  No presumption as to construction of this Agreement shall apply against either Party with respect to any ambiguity in the wording of any provision(s) of this Agreement irrespective of which Party may be deemed to have authored the ambiguous provision(s).

(b)      No Response.   Where a provision of this Agreement provides for a Party to respond within a designated period following written notice from the other Party (e.g., Sections 5.1(a)(vi) and 5.1(b)(iv)), and if such Party fails to respond within the designated period, then the failure to respond shall create or imply:  (i) that the non-responding Party agrees with the proposed action to be taken by the other Party, or (ii) consent that an action proposed to be taken may be taken, except if such consent expressly conflicts with the terms of this Agreement.
