Ahairstylist entered into a contract with a hairspray manufacturer in which the manufacturer agreed to supply the hairstylist with all of its "long lasting" hairspray (reputed to be the longest lasting in the industry) that the hairstylist would need over the next five years. in the second year of the contract, the hairspray manufacturer learned that the hairstylist was "butchering" high-profile clients' hair and using the hairspray to hold the style, and feared that the negative publicity would harm its reputation and decrease sales. it sent a letter to the hairstylist stating that it would send no more hairspray. if the hairstylist files suit for specific performance against the manufacturer, will he prevail?
