A non-disclosure agreement is optional in a business plan. When used, it usually states that the information in the plan is proprietary and not to be shared, copied or disclosed. The agreement should have a unique "copy number" that is the same as a number on the front of the plan and a place for the recipient's signature. The agreement should be either a loose leaf page or a page that can be torn out of the plan and retained by the enterprise.
Example:COPY NUMBER ______________
