(e) If further studies, including toxicity studies, are required or suggested by a Regulatory Authority as a prerequisite for conducting any of the Combined Therapy Trials, then the Parties agree to hold good faith discussions in a timely manner to agree upon a protocol for such studies, each of which will be considered a Combined Therapy Trial and conducted on substantially the same terms as set forth herein (including the cost-sharing provisions of Section 7.1); provided that, if the Parties are unable to agree upon a protocol for such study or if the conduct of such study shall cause a delay deemed unsatisfactory by either Party, then any disputed matters precluding agreement shall be referred to the Executive Officers (or their respective designees) for resolution. If the Executive Officers are unable to reach resolution within ten (10) Business Days after such referral to them (and do not mutually agree to an extension of time to arrive at such resolution), then this Agreement shall automatically terminate following the conclusion of any then-active Combined Therapy Trial (unless and until the Protocol for such required/suggested study(ies) is finalized by mutual agreement prior to the completion of such Combined Therapy Trial) and the provisions of Section 12.8 shall apply to any such termination.

2.2 Safety Reporting – Safety Data Exchange Agreement. Within three (3) months of the Effective Date, or as soon as practicable thereafter, and in any event prior to Initiation of the first Combined Therapy Trial, the Parties (under the guidance of their respective safety departments, or equivalents thereof) shall define and finalize their respective responsibilities to protect patients and promote their well-being in connection with the use of the Nektar Compound and the BioXcel Compound in the framework of this Agreement, and to execute a “Safety Data Exchange Agreement.” Such Safety Data Exchange Agreement shall include mutually acceptable procedures for the receipt, investigation, recordation, communication, and exchange (as between the Parties) of adverse event reports, pregnancy reports, and any other information concerning the safety of the Nektar Compound, the BioXcel Compound and the CPI Compound. Such procedures shall be in accordance with, and enable the Parties and their Affiliates, to fulfill, local and international regulatory reporting obligations to government authorities. Furthermore, such agreed procedures shall be consistent with relevant International Council for Harmonization (ICH) guidelines, except where said guidelines may conflict with existing local regulatory safety reporting requirements or Applicable Law, in which case local reporting requirements or

Applicable Law shall prevail. To the extent any provision set forth in the Safety Data Exchange Agreement conflicts with any provision in this Agreement, the provision set forth in the Safety Data Exchange Agreement shall control as related to the exchange and reporting of safety information associated with use of the Nektar Compound, the BioXcel Compound and the CPI Compound, as well as product safety surveillance. In the event that this Agreement is terminated, the Parties agree to implement the necessary procedures and practices to ensure that any outstanding pharmacovigilance reporting obligations are fulfilled.

If Nektar determines either: (a) not to continue the preparation, prosecution or maintenance of a Patent application or Patent within the Combined Therapy Patent Rights; or (b) not to file any new Patent application within the Combined Therapy Patent Rights as requested to be filed by BioXcel, in each case, other than to optimize overall Patent protection of claimed inventions, Nektar shall provide BioXcel with notice of this decision within [***] ([***]) days of any decision not to file a new Patent application, or at least [***] ([***]) days prior to any pending lapse or abandonment of an existing Patent application or Patent. In such event, Nektar shall provide BioXcel with an opportunity to assume responsibility for all costs associated with the filing or further preparation, prosecution and maintenance of such Patent application or any Patent issuing thereon (such filing to occur prior to the issuance of the Patent to which the application claims priority or expiration of the applicable filing deadline, as set forth above). If BioXcel assumes such responsibility for such preparation, filing, prosecution and maintenance costs, BioXcel shall have the right to transfer the responsibility for such preparation, filing, prosecution and maintenance of such Patent applications and/or Patents to patent counsel selected by it and reasonably acceptable to Nektar. In such case, Section 6.1(c) shall apply to such Patent applications and Patents mutatis mutandis. Such Patent applications and Patents shall otherwise continue to be subject to all of the terms and conditions of this Agreement in the same manner and to the same extent as the other Patent applications and Patents within the Combined Therapy Patent Rights.

(ii) Failure to Reimburse. If a Party elects not to reimburse the other Party for [***] percent ([***]%) of the costs and expenses of preparation, filing, prosecution and maintenance of a Patent application or Patent within the Combined Therapy Patent Rights in a given country, the non-reimbursed Party shall have the right, but not an obligation, to prepare, file, prosecute or maintain such Patent application or Patent in such country in its own name and at its own expense, with the prior written consent of the other Party (which shall not be unreasonably withheld) and the other Party shall promptly assign, without additional consideration, all of its rights, title and interest to the Patent application or Patent in said country and any inventions covered by such Patent application or Patent to the non-reimbursed Party if the non-reimbursed Party wishes to prepare, file, prosecute or maintain said Patent application or Patent. After giving effect to such assignment, such assigned invention and any corresponding Combined Therapy Patent Rights thereto shall be the treated as a BioXcel Independent Patent Rights or Nektar Independent Patent Rights, as applicable. The Party who does not wish to prepare, file, prosecute or maintain a Patent application or Patent within the Combined Therapy Patent in any country shall assist in the timely provision of all documents required under national provisions to register said assignment of rights with the corresponding national authorities at the sole expense of the Party who wished to prepare, file, prosecute or maintain such Patent application or Patent in that given country. Nektar shall have the right to disclose to BMS, subject to the confidentiality provisions of the SCA governing disclosures of Nektar confidential information to BMS, applications for Patents, amendments thereto, assignment-related documents and other related correspondence to and from Patent offices contemplated by this subsection (ii) to the extent necessary to comply with Nektar’s obligations under the SCA, provided that Nektar shall not disclose any confidential information of the CPI Compound supplier in connection therewith (to

be clear, nothing in the foregoing proviso shall prohibit Nektar from disclosing the Combined Therapy Study Data to BMS on the terms provided herein); and provided further, that Nektar remains liable to BioXcel for any breach by BMS of such confidentiality provisions.

COLLABORATION COSTS AND EXPENSES

7.1 Combined Therapy Trial Expenses. Expenses incurred as described in Article 4 (regarding Manufacturing and supply up to the point where the applicable BioXcel Compound or Nektar Compound arrives at the BioXcel labeling and distribution facility for the applicable Combined Therapy Trial), and Article 6 (regarding intellectual property) shall be borne or shared by the Parties as provided in such Articles. In addition, each Party shall bear its own Third Party License Payments as set forth in Section 2.6(b). For all other expenses that are directly attributable or reasonably allocable to the conduct of the Combined Therapy Trials, (a) Nektar will be responsible for [***] percent ([***]%) of all out-of-pocket costs paid to Third Parties (including taxes, to the extent non-creditable to BioXcel) reasonably incurred in connection with Third Party Contractors, CROs, laboratories and clinical sites/IRBs or otherwise by either Party in connection with the performance of the Combined Therapy Trials including, but not limited to, BioXcel’s out-of-pocket costs of labeling and packaging the unlabeled vials of the Nektar Compound provided by Nektar, labeling and packaging the commercially labeled vials of the CPI Compound provided by the CPI Compound supplier, and labeling and packaging the BioXcel Compound, in each case for distribution to clinical sites, and those costs described under Section 8.5, and that are incurred consistent with the JDC-approved budget for each Combined Therapy Trial (“Third Party Study Costs”); and (b) each Party shall be solely responsible for all of its own internal costs (including all internal full-time equivalents and all costs of individuals engaged as independent contractors) incurred by such Party or any of its Affiliates in the performance of each Combined Therapy Trial, to the extent not included in the definition of Third Party Study Costs. For the avoidance of doubt, Third Party Study Costs does not include Third Party License Payments by Nektar, Third Party License Payments by BioXcel or any Third Party Claims.

7.2 Invoicing; Payment.

(a) Designation of Finance Representatives; Reconciliation.

(i) Each of the Parties shall designate a representative from its Finance Department to interact with the designee of the other Party concerning preparation of the budget for each Combined Therapy Trial (including the Initial Trial) for approval by the JDC, reconciliation of costs incurred in the conduct of each Combined Therapy Trial, the method to be used by both Parties to determine the amounts to be invoiced by BioXcel to Nektar hereunder, and to act as the point of contact for any other matters arising between the Parties under Article 7 (the “Finance Representatives”). Nektar shall reimburse BioXcel, on a quarterly basis in arrears, for Nektar’s [***] percent ([***]%) share of all Third Party Study Costs under U.S. Generally Accepted Accounting Principles incurred by BioXcel during the prior quarter.

If requested by Nektar in writing, BioXcel shall provide invoices or other appropriate supporting documentation for any payments to a Third Party exceeding [***] United States dollars ($[***]). If requested by Nektar in writing, BioXcel shall provide a reconciliation between the cumulative amounts paid and the expenses recorded by BioXcel for the Combined Therapy Trial as reported under U.S. Generally Accepted Accounting Principles. The Parties shall seek to resolve any questions related to such invoices and/or Quarterly Reports within [***] ([***]) Business Days following receipt by Nektar of BioXcel’s invoice and Quarterly Report hereunder. Based on the invoices and reports, payment will be made by Nektar within [***] ([***]) calendar days after the delivery of such invoice and Quarterly Report. If Nektar disputes an amount due on an invoice, Nektar will notify BioXcel of such dispute within [***] ([***]) Business Days of receipt of such invoice and shall pay the amount not in dispute after BioXcel submits a new invoice for the undisputed amount. The Parties shall use good faith efforts to discuss and resolve any disputed amounts. Any undisputed invoiced amount which is not paid by its due date shall be assessed a late payment fee at the rate of one percent (1%) per month, compounded monthly, or at the highest rate permitted under Applicable Law, if less.

(ii) BioXcel shall reimburse Nektar, on a quarterly basis in arrears, for BioXcel’s [***] percent ([***]%) share of all costs and expenses incurred by Nektar under Article 6, actually invoiced to Nektar by Third Parties during the prior quarter. Within [***] ([***]) Business Days of the end of each quarter, Nektar shall (1) submit to BioXcel an invoice for BioXcel’s [***] percent ([***]%) share of all such Article 6 costs and expenses, and (2) an electronic report that specifies in reasonable detail all such Article 6 costs expenses during such quarter (a “Quarterly Patent Costs Report”). All Nektar invoices to BioXcel shall be in United States dollars. Third Party expenses incurred by Nektar in a currency other than United States dollars shall be converted to United States dollars by Nektar using Nektar’s standard currency conversion methodology consistently applied. BioXcel agrees to accept electronic copies of

invoices and reports, in .pdf format, emailed to BioXcel at an address provided by the BioXcel Alliance Manager as sufficient delivery thereof to process payments to Nektar. If requested by BioXcel in writing, Nektar shall provide invoices or other appropriate supporting documentation for any payments to a Third Party exceeding $[***]. If requested by BioXcel in writing, Nektar shall provide a reconciliation between the cumulative amounts invoiced to BioXcel and the expenses recorded by Nektar for the Combined Therapy Trial as reported under U.S. Generally Accepted Accounting Principles.

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.

TERM AND TERMINATION

12.1 Term. This Agreement shall be effective as of the Effective Date and, unless earlier terminated pursuant to Sections 12.2, 12.3 or 12.4 or any other termination right expressly stated in this Agreement, shall continue in effect until completion by all centers or institutions participating in the Combined Therapy Trials, the delivery of all Study Data, including all completed case report forms, all final analyses and all final clinical study reports contemplated by the Combined Therapy Trials, to both Parties, and the completion of any then agreed upon Protocol, Statistical Analysis and Bioanalysis Plan (the “Term”); provided that if termination language in Sections 2.1(e) applies, then the Term shall expire.

12.2 Termination for Material Breach.

(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 [***] ([***]) calendar days 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.

(b) Termination Right. The Non-Breaching Party shall have the right to terminate this Agreement, 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 [***] ([***]) calendar days to cure such breach. If a Party contests such termination pursuant to the dispute resolution procedures under Section 13.3, such

termination shall not be effective until a conclusion of the dispute resolution procedures in Section 13.3, 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).

12.3 Termination for Bankruptcy. Either Party may terminate this Agreement if, at any time, the other Party shall file in any court or agency pursuant to any statute or regulation of any state, country or jurisdiction, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of such other Party or of such other Party’s assets, or if the other Party proposes a written agreement of composition or extension of its debts, or if the other Party shall be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed or stayed within [***] ([***]) calendar days after the filing thereof, or if the other Party will propose or be a party to any dissolution or liquidation, or if the other Party shall make an assignment for the benefit of its creditors.

12.4 Termination due to Material Safety Issue; Clinical Hold.

(a) Either Party shall have the right to terminate this Agreement immediately upon written notice if it reasonably deems it necessary to protect the safety, health or welfare of subjects enrolled in any Combined Therapy Trial due to the existence of a Material Safety Issue. In the event of a termination 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 processes set forth in Sections 2.8 or 13.3 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 Sections 2.8 or 13.3.

(b) If a Clinical Hold with respect to the Nektar Compound, CPI Compound or the BioXcel Compound 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 ninety (90) calendar days of discussions following the Clinical Hold, either Party reasonably concludes that the issue is not solvable or that unacceptable and material additional costs/delays have been and/or will continue to be incurred in the conduct of the Combined Therapy Trial, then such Party may immediately terminate this Agreement.

12.5 Termination by Nektar for Breach of SCA. In the event that Nektar receives a notice from BMS that any action taken or that the taking of any action under this Agreement by either Nektar of BioXcel has caused or will cause Nektar to be in breach of the SCA, and such breach cannot be cured in accordance with the terms of the SCA, Nektar shall have the right to terminate this Agreement on at least [***] ([***]) days prior written notice to BioXcel.

12.6 Termination by Nektar related to BioXcel Diligence Failure. Nektar shall have the right to terminate this Agreement on at least [***] ([***]) days prior written notice to BioXcel in the event that BioXcel fails to achieve any of the Diligence Targets for the Initial Trial within [***] ([***]) days of the target date set forth in Section 2.6(a), provided, that (a) Nektar’s notice of termination under this Section shall specifically cite the Diligence Target or Diligence Targets that BioXcel failed to achieve, (b) prior to Nektar terminating pursuant to this Section, the JDC shall meet and discuss the reason for such failure, and if the reason was other than due to BioXcel’s breach or negligence, the JDC shall extend the time period(s) for achieving such Diligence Target(s) for the period of time caused by such circumstance that was not due BioXcel’s breach or negligence, and (c) Nektar’s right to terminate this Agreement pursuant to this Section 12.6 shall not be available to Nektar in the event that BioXcel’s failure to meet a Diligence Target cited in the Nektar notice of termination was due in whole or in part to (i) the failure of Nektar to perform an obligation of Nektar set forth in this Agreement or Nektar’s breach or misconduct; or (ii) the failure of the Parties to agree on terms for obtaining a CPI Compound.

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.

12.8 Effect of Termination. Upon expiration or termination of this Agreement, (a) the licenses granted to each Party to conduct a Combined Therapy Trial in Sections 3.1 and 3.2 shall terminate, and (b) the Parties shall use reasonable efforts to wind down activities under this Agreement in a medically reasonable manner and avoid incurring any additional expenditures or non-cancellable obligations; provided that, if sufficient quantities of the Nektar Compound and the CPI Compound are available, (i) in the case of termination pursuant to Section 12.4, BioXcel may continue to dose subjects enrolled in any then ongoing Combined Therapy Trial through completion of the applicable Protocol if dosing is required by the applicable Regulatory Authority(ies) and/or Applicable Law(s); and (ii) in the case of termination by Nektar pursuant to Section 12.5, BioXcel may continue to dose subjects enrolled prior to receipt of the termination notice from Nektar in any then ongoing Combined Therapy Trial through completion of the applicable Protocol. Any such wind-down activities will include the return to Nektar, or destruction, of all Nektar Compound provided to BioXcel and not consumed in the Combined Therapy Trials. If applicable, upon termination of this Agreement, the Parties shall remain responsible pursuant to the terms of this Agreement for any expenses incurred prior to such termination and that are associated with terminating any ongoing clinical trial work and/or result from such ongoing activities under this Agreement solely to the extent such activities are deemed necessary by BioXcel (after discussion at a meeting of the JDC) based on reasonable medical judgment to protect the health of subjects participating in any Combined Therapy Trial.

13.3 Dispute Resolution.

(a) In the event of any dispute, controversy or claim arising out of, relating to or in connection with any provision of this Agreement (each a “Dispute”), other than a JDC Dispute or a Publication Dispute or a dispute as to whether a Material Safety Issue exists, the Parties shall refer such Dispute promptly to the Alliance Managers for resolution. If the Alliance Managers are unable to resolve such Dispute within ten (10) calendar days after a matter has been presented to them, then upon the request of either Party by written notice, the Parties shall refer such Dispute to the Executive Officers. This Agreement shall remain in effect during the pendency of any such dispute. In the event that no resolution is made by them in good faith negotiations within ten (10) calendar days after such referral to them, such unresolved Dispute shall be referred to the Chief Executive Officer of BioXcel or his or her designee and the Chief Scientific Officer of Nektar or his or her designee for attempted resolution by good faith negotiations within fifteen (15) calendar

days after such referral is made. In the event such officers are unable to resolve such Dispute within such fifteen (15) calendar day period then, if such Dispute constitutes an Arbitration Matter, such Dispute shall be resolved through arbitration in accordance with Section 13.3(b); provided, however, that with respect to any such Dispute that relates to a matter described in Section 13.4, either Party shall have the right to seek an injunction or other equitable relief without waiting for the expiration of such fifteen (15) calendar day negotiation period, and with respect to any JDC Dispute or Publication Dispute, the specific dispute resolution processes contained in Sections 2.8 or 9.5(b), as applicable, will apply.

(b) 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.

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.

13.4 Injunctive Relief. Notwithstanding anything herein to the contrary, a Party may seek an injunction or other injunctive relief from any court of competent jurisdiction in order to prevent immediate and irreparable injury, loss or damage on a provisional basis.

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.

(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.
