Public Announcement. Except as set forth in Section 7.9 (Press Release), neither Party shall make, nor permit any person to make, any public announcement, whether oral or written, concerning the Agreement that is not previously disclosed or otherwise in the public domain, or make any use of the name, symbol, trade mark, trade name or logo of the other Party or its Affiliates without the prior written consent of the other Party (such consent not to be unreasonably withheld or delayed).

Pyxis will provide to LCB a certificate evidencing the insurance it is required to obtain and shall keep in force such policy upon LCB’s reasonable request during the Term. Such certificate will evidence that LCB is an additional insured. Notice of cancellation or material change will be made in accordance with the policy provisions.

Term and Termination

Termination.

Termination for Material Breach. Either Party may terminate the Agreement at any time by notice in writing to the other Party, such notice to take effect [***] from receipt of such notice if such other Party is in material breach of the Agreement (including failure to make any payment, which failure shall automatically be deemed a material breach, or Commercially Reasonable Efforts or breach of any provisions of Article 6 or 7), unless the breach is failure to make a payment, in which case the notice will take effect [***] from receipt. If such breach can be cured within such [***] period (or [***] period in the case of failure to make a payment), then such termination will not be effective if the breaching Party promptly commences actions to cure such breach and thereafter diligently continues such actions and cures such breach during such [***] period after such notice. If an allegedly breaching Party disputes the occurrence of the material breach, then the cure period set forth in this Section 10.2(a) (Termination for Material Breach) shall be tolled during the period that the alleged material breach is being disputed in accordance with Sections 11.1 (Disputes) and 11.2 (Arbitration) of the Agreement, until the dispute is finally resolved.

Dispute Resolution and Governing Law

Disputes. Any dispute between the Parties arising out of or relating to the Agreement, including any non-contractual disputes or claims or any question regarding its existence, validity, or termination, shall be resolved by binding arbitration. The proceedings shall be initiated by the service of a written notice of dispute by a Party on the other Party setting out details of the dispute and the reasons why the Party serving the notice believes that the dispute has arisen. Upon service of such a notice, the dispute shall be referred to the Senior Officers (or their respective delegates), who shall endeavour to resolve the dispute amicably (each acting reasonably and in good faith).

Arbitration. In the event that a dispute cannot be resolved to the satisfaction of both Parties within [***] of referral to the Senior Officers (or their respective delegates), or if a Party either fails to participate or to continue to participate in the process referred to in Section 11.1 (Disputes), it shall be finally settled through an arbitration in accordance with the Rules of Arbitration of the International Chamber of Commerce 2021 in accordance with the Expedited Procedure Rules irrespective of the amount in dispute.

The arbitration tribunal shall be composed of one arbitrator agreed by the Parties. If the Parties are unable to agree on an arbitrator within [***] after the transmission of the request for arbitration by one of the Parties, then the arbitration tribunal shall be composed of one arbitrator selected by each Party and one arbitrator selected by the first two arbitrators. The arbitral award shall be final and binding. A judgment on any award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof. The legal seat of arbitration shall be Boston, Massachusetts, and the language of the arbitral proceedings shall be English. Either party may apply to the arbitrator(s) seeking injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. The arbitrators shall have the authority to grant specific performance, issue summary judgments or grant other depository motions and, if either Party engages attorneys to enforce any rights arising out of or relating to the Agreement, then the prevailing Party shall be entitled to recover its reasonable fees and costs expended in engaging such attorneys. The Parties agree that all information, including the result, of such arbitration and the fact that arbitration takes place shall be regarded as Confidential Information of both Parties and shall not be disclosed without the written consent of the other Party.

The Agreement (and any dispute or claim relating to it, its subject matter, its enforceability or its termination, including non-contractual claims) is governed by and construed in accordance with the substantive laws of Massachusetts without regard to its conflicts of law provisions.

Other Remedies. Nothing in the Agreement shall prevent either Party or their Affiliates from seeking interim relief or a temporary restraining order or injunction concerning a dispute either prior to or during any proceeding if necessary to protect the interests of such Party or to preserve the status quo pending the proceeding, including any such remedy against the Receiving Party from any court of competent jurisdiction in the event of a threatened or actual breach of any confidentiality obligation hereunder, or to prevent wrongful use of any Confidential Information hereunder without posting of a bond or other security.

General

No other license. Nothing in the Agreement shall be construed as giving to either Party any rights to use any Intellectual Property Rights other than as expressly granted by the Agreement.

Amendment. The Agreement may only be amended in writing signed by duly authorized representatives of Pyxis and LCB.

Assignment.

Subject to Section 12.3(b), neither Party may assign, mortgage, charge, or otherwise transfer any rights or obligations under the Agreement without the prior written consent of the other Party.

With written notice to the other Party before such assignment or transfer, either Party may assign and transfer all its rights and obligations under the Agreement to (i) an Affiliate, or (ii) any counter-party to a Change of Control transaction, provided that the assignee undertakes in writing to the other Party to be bound by and perform the obligations of the assignor under the Agreement. Any assignment or attempted assignment by either Party in violation of the terms of this Section 12.3 (Assignment) will be null, void and of no legal effect.

Waiver. No failure or delay on the part of either Party to exercise any right or remedy under the Agreement shall be construed or operate as a waiver thereof, nor shall any single or partial exercise of any right or remedy preclude the further exercise of such right or remedy.

Invalid Clauses. If any provision or part of the Agreement is held to be invalid, amendments to the Agreement may be made by the addition or deletion of wording as appropriate to remove the invalid part or provision but otherwise retain the provision and the other provisions of the Agreement to the maximum extent permissible under applicable law such that the objectives contemplated by the Parties when entering into the Agreement may be realized.

No agency. Neither Party shall act or describe itself as the agent of the other, nor shall it make or represent that it has authority to make any commitments on the other’s behalf. Each Party will act solely as an independent contractor, and nothing in the Agreement will be construed to give either Party the power or authority to act for, bind, or commit the other Party in any way. Nothing herein will be construed to create the relationship of partners, principal and agent, or joint-venture partners between the Parties.

Performance by Affiliates. Each Party may perform any obligations and exercise any right hereunder through any of its Affiliates, provided that such Party will remain primarily responsible for the other Party hereunder. Each Party hereby guarantees the performance by any of its Affiliates of such Party’s obligations under the Agreement, and will cause its Affiliates to comply with the provisions of the Agreement in connection with such performance. Any breach by a Party’s Affiliate of any of such Party’s obligations under the Agreement will be deemed a breach by such Party, and the other Party may proceed directly against such Party without any obligation to first proceed against such Party’s Affiliate.

Force Majeure. Neither Party will be held liable to the other Party nor be deemed to have defaulted under or breached the Agreement for failure or delay in achieving any objective, satisfying any condition, or performing any obligation under the Agreement to the extent that such failure or delay is caused by or results from acts or events beyond the reasonable control of such Party, including acts of God, embargoes, war, acts of war (whether war be declared or not), terrorism, insurrections, riots, civil commotions, government actions, unavailability of supplies, materials or transportation, fire, earthquakes, floods, epidemics, pandemics, the spread of infectious diseases, and quarantines (“Force Majeure”). The affected Party will notify the other Party in writing of any Force Majeure circumstances as soon as reasonably practical, will provide a good faith estimate of the period for which its failure or delay in performance under the Agreement is expected to continue based on currently available information and shall use best efforts to mitigate the effects such Force Majeure and promptly resume performance upon the cessation thereof.
