An NDA, or non-disclosure agreement, is the confidentiality agreement a buyer signs before it learns the name of the business or receives the CIM, limiting what it may do with what it learns.
In a sale
Because the CIM names the business and sets out its financials: buyers first see a one-page teaser with no name on it, and only those who sign an NDA receive the CIM. The standard form FNDRS uses lets a buyer use what it learns only to evaluate, negotiate, and close this sale, and bars it from contacting your employees, customers, or suppliers about the sale without written consent. The agreement each buyer signs governs, and its terms can differ.
