How do we know what performance is required for a sale or lease agreement and how will we know if a breach has occurred? The following case will help us with these questions.

Bobby Murray Chevrolet, Inc., contracted to supply 1,200 school bus chassis to local school boards. The contract stated that "products of any manufacturer may be offered," but Bobby Murray submitted its orders exclusively to General Motors Corp. (GMC). When a shortage in automatic transmissions occurred, GMC informed the dealer that it could not fill the orders. Bobby Murray told the school boards, which then bought the chassis from another dealer. The boards filed a suit in a North Carolina state court against Bobby Murray for breach of contract. The dealer responded that its obligation to perform was excused under the doctrine of commercial impracticability, in part because of GMC's failure to fill its orders.
