Force Majeure Clauses in Vendor Contracts: What They Cover in a Supply Disruption
What a force majeure clause actually excuses in a medical-supply or lab-equipment vendor contract, what it doesn’t (ordinary supply tightness or a vendor’s own operational failure), and why continuity planning still needs a real second source.
Limitation of Liability Clauses in Vendor Contracts: What the Cap Actually Covers
Plain-language explanation of what a limitation of liability clause caps in a vendor contract, and the practical question that matters more than the dollar figure: whether the cap also applies to the vendor’s indemnification obligation, or whether that’s carved out.
Confidentiality and NDA Clauses in Vendor Relationships: What’s Typically Covered
A vendor confidentiality clause protects pricing, product-roadmap, and business information exchanged during the relationship — it is not a HIPAA Business Associate Agreement and does not satisfy HIPAA on its own.
