Service Delivery
Services may be delivered remotely, on-site at Client premises, or in a hybrid format as agreed in the Proposal. Travel expenses for on-site work are invoiced separately unless included in the fixed fee.

Successful delivery requires active Client participation. The Client agrees to provide timely access to relevant personnel, systems, data, and facilities as reasonably required. Delays caused by lack of Client cooperation may result in timeline extensions and additional costs.

14. EU AI Act Compliance for Delivered AI Systems
When Hyperion Consulting designs, develops, integrates, or materially modifies an artificial intelligence system on behalf of the Client, the following allocation of responsibilities under Regulation (EU) 2024/1689 (the 'AI Act') applies:
Provider vs Deployer
Unless otherwise explicitly agreed in writing in the Proposal, the Client is the 'provider' of the AI system within the meaning of Article 3(3) of the AI Act when the system is placed on the market or put into service under the Client's name or trademark. Hyperion Consulting acts as a technical contractor to the provider. When the Client uses an AI system developed by Hyperion Consulting as part of its own operations, the Client is the 'deployer' within the meaning of Article 3(4).
Risk Classification
Prior to delivery, Hyperion Consulting will perform and document a risk-classification assessment under Articles 6-7 and Annex III of the AI Act. Where a system falls into a high-risk category, Hyperion Consulting will provide the Client with: (a) a technical documentation file meeting Annex IV requirements; (b) instructions for use under Article 13; (c) information necessary to perform a Fundamental Rights Impact Assessment under Article 27 if applicable; (d) logging capabilities under Article 12; (e) human oversight measures under Article 14.
Prohibited Practices
Hyperion Consulting shall not develop, deliver, or support any AI system whose intended purpose constitutes a prohibited practice under Article 5 of the AI Act, including social scoring, subliminal manipulation, exploitation of vulnerabilities, emotion recognition in the workplace or educational institutions (save for medical or safety reasons), biometric categorization based on sensitive attributes, untargeted facial-image scraping, or real-time remote biometric identification in publicly accessible spaces for law enforcement (save for the narrow exceptions listed therein).
General-Purpose AI Models
When a delivered system integrates a General-Purpose AI (GPAI) model within the meaning of Article 51, Hyperion Consulting will identify the upstream provider and pass through the information required under Article 53(1)(b) to enable the Client to comply with its own obligations.
AI Literacy (Article 4)
In accordance with Article 4 of the AI Act, the Client is responsible for ensuring a sufficient level of AI literacy among its staff operating delivered AI systems. Hyperion Consulting offers AI literacy training as part of its standard service catalogue and will recommend an appropriate programme at the Client's request.
Transparency Obligations (Article 50)
For AI systems intended to interact directly with natural persons, generate synthetic audio/video/text/images, or perform emotion recognition or biometric categorization, Hyperion Consulting will build in the transparency disclosures required by Article 50 at the user interface level prior to delivery. The Client remains responsible for ensuring these disclosures remain in place throughout the lifecycle of the system.
Conformity Assessment
Where a delivered system qualifies as high-risk, the Client (as provider) is responsible for carrying out the applicable conformity assessment under Article 43 and affixing the CE marking under Article 48 prior to placing the system on the EU market or putting it into service. Hyperion Consulting will provide reasonable technical cooperation and documentation required for the assessment.
15. Professional Liability Insurance
Hyperion Consulting maintains professional liability insurance (Responsabilité Civile Professionnelle) covering its consulting activities.
Certificate of insurance is available upon request.
16. Governing Law & Disputes
Governing Law
These Terms and all engagements are governed by the laws of France, without regard to conflict of laws principles.
Jurisdiction
Any disputes arising from these Terms or related engagements shall be subject to the exclusive jurisdiction of the Commercial Court of Nanterre, France.
B2B Mediation
Before initiating formal proceedings, the parties agree to attempt resolution through good-faith negotiation for a minimum period of 30 days. If negotiation fails, the parties agree to submit the dispute to mediation before the Centre de Médiation et d'Arbitrage de Paris (CMAP) before proceeding to litigation.
Dispute Resolution
If mediation fails or if either party refuses mediation, disputes shall be submitted to the Commercial Court of Nanterre, France.
