IF there is a deal in the works, usually there is a fee negotiated for if the deal does not go through. It is a good faith deal that shows the companies are serious and there are penalties for not proceeding because it takes the principals away from their assigned jobs to accomplish all the questions that need to be answered in due diligence and the lawyer fees accounted for. IF there is a deal brewing, I’d bet this is in place because of the size and the few employees that are associated with this work in the company. It would take a bulk of their time to get through it. Just an added observation as to no communication.
