PSJ denied franchisor. Held that 7-day period for repudiation of mutual termination does not preempt franchisee's state law defense that franchisor prevented him from exercising the repudiation right by boarding up the premises before the 7 days expired causing franchisee to remove his belongings and claim he did not think he could undo such action by a piece of paper. Held the prevention of condition defense argument fails as a matter of law, but there was an issue of material fact about his economic duress defense.
