On May 1, Juno Properties, Inc., a commercial property owner, asks Erik Woodruff, a real estate agent, to help market and sell Juno Properties' office building. Under the terms of Juno Properties' offer, if a buyer makes a serious offer to buy the building within sixty days, Juno Properties must pay Erik's commission. Erik puts signs on the building, ads in real estate pamphlets and a locally focused Web site, features the property in a "walking" tour online, and shows the building to potential buyers. On June 1, Juno Properties tells Erik that it is canceling their arrangement. Five days later, Juno Properties closes a sale on the building without Erik's participation. Erik files a suit against Juno Properties for the amount of his commission. In whose favor is the court likely to rule, and why?
