Ryan has worked as a purchasing agent for Coastal Carolina University for many years and his office is located in the Singleton building. On Monday, William, a CCU corporate officer, gives Ryan written authority to buy for CCU as many shelving units and paper supplies as necessary. On Tuesday, William calls Ryan on the phone and tells him to buy only 50 shelving units and nothing else. On Wednesday, Ryan shows the original written authority to Office Supply, Inc., and enters into a contract with Office Supply to buy 60 shelving units and a selection of writing supplies, pens and paper. Office Supply ships the order to CCU.

Is CCU liable to Office Supply under the contract? Is Ryan liable? In each case, if so, why and how much? If not, why not?
