Greg Schiano would have earned $27.7 million in a proposed deal of six-plus years with Tennessee before the deal fell apart because of uproar from fans and on social media.
The school on Monday released a copy of the memorandum of understanding (MOU) between John Currie, who has since been replaced by Phillip Fullmer as athletic director, and Schiano.
ESPN had reported last month that the MOU was never signed by Chancellor Beverly Davenport, which was likely to lead to a battle over whether Tennessee owed Schiano any money.
The MOU, which ESPN obtained through an open records request, says the terms are binding and does not say that the lack of a signature by any party makes it invalid.
