You shall not remove, modify, or obscure any IPR notices on the Nexus Platform or related documentation.

If we determine the above is not practicable, then we may suspend or terminate your use of the Nexus Platform.
All information one party receives from the other party in performance of these T&Cs that is generally not known (“Confidential Information”) shall be held in strictest confidence and shall not, without the written consent of the disclosing party, be disclosed except to the receiving party’s Affiliates, employees and service providers who are bound to substantially similar obligations of confidentiality and have a need to know. The receiving party may only use the disclosing party’s Confidential Information to the extent necessary to perform its obligations or receive the benefit of the rights granted under these T&Cs. Each party will be responsible for any breaches of the confidentiality obligations by its Affiliates, employees or service providers or Authorized Users.

We may use, provide or allow access to open-source software (including open source software developed by Quantinuum or its Affiliates) (“OSS”), or software or hardware owned or developed by third parties or Quantinuum (including but not limited to freeware and commercial software or hardware) that is provided under a separate proprietary license (together with OSS “Independent Components”). We may make Independent Components available in connection with the Nexus Platform via the Nexus Platform Site or other portal or through a web-based hosting service such as GitHub or via a REST API web interface. To the extent required by the licenses covering Independent Components (“Independent Components Terms”), the terms of such Independent Components Terms will apply to Independent Components in lieu of these T&Cs. Independent Components Terms in respect of Independent Components distributed by the Nexus Platform are set out in Schedule 1 (this does not include Independent Components that are only accessed via the Nexus Platform, for example, you or your organization may have access to other OSS or may have signed additional Independent Components Terms for other separate products that may be accessible through but not provided by the Nexus Platform such as subscription agreements for Quantum System hardware access or InQuanto software access, which would apply to such Independent Components). To the extent Independent Components Terms applicable to OSS: (a) prohibit any restriction with respect to such OSS, such restriction will not apply to such OSS and (b) require us to make an offer to provide source code or related information in connection with the OSS, such offer is hereby made.
You acknowledge and agree that Quantinuum shall have no liability to you from any claims resulting from your use of Independent Components under these T&Cs. Quantinuum may treat your and your Users’ breach of any Independent Components Terms as a breach of these T&Cs.

These T&Cs will be binding upon, inure to the benefit of, and be enforceable by, the Parties hereto and any successors and assigns.

Application of the United Nations Convention on Contracts for the International Sale of Goods, 1980, and any successor law to either is specifically excluded. The courts of England and Wales have exclusive jurisdiction to adjudicate any dispute arising out of or related to these T&Cs.

We may update the Nexus Platform as we determine necessary to keep up to date with technology developments relevant to the Nexus Platform and security practices or to add new features. Any descriptions of future product direction or intended updates (including new or improved features or functions) other than the features and functions deployed as of date of these T&Cs are intended for information purposes only and are not binding commitments on us to deliver any material, code, or functionality. The development, release, and timing of any such updates is at our sole discretion unless agreed otherwise in writing.

10.9 Hosting
You acknowledge that the Nexus Platform is hosted using services provided by Amazon Web Services Inc. (or one of its Affiliates) (“Amazon”) (such services being the “Hosting Services”), which shall be governed by and are to be provided by Amazon in accordance with the publicly applicable terms specified by Amazon from time to time as applying between it and Quantinuum (collectively the "AWS Terms"), including https://aws.amazon.com/service-terms/. You acknowledge that the Nexus Platform shall not be provided to a standard or service level higher than that indicated by the AWS Terms.
You agree that (except in relation to any liability which cannot be limited or excluded as a matter of law):
we shall not be liable to you (including under any legal theory, including in negligence) in connection with the Hosting Services (or any failure of the Hosting Services) save to the extent such liability arises from a breach of these T&Cs that is also a breach by Amazon of the applicable AWS Terms; and
without prejudice to the additional limitations and exclusions of our liability in Clause 8 of the T&Cs, our liability to you (howsoever arising, including in negligence) in connection with the Hosting Services (or any failure of the Hosting Services) shall not exceed the amounts we are able to recover from Amazon under the AWS Terms in respect of your loss in such circumstances.
