Pacific Cascade Corporation (PCC), of Seattle, Washington, is engaged in the business of commercial real estate development. Its principal client, Modern Merchandising, Inc., operates "Jafco" stores throughout the Pacific Northwest. In March 1977, PCC, at the request of Modern Merchandising, began looking for a site for a new Jafco store in Spokane, Washington. Through a local real estate agent, PCC became interested in certain property, known as the Auto Vue Drive-In, owned by the defendant, Morrie G. Nimmer.
On April 15, Mr. Nimmer and the president of PCC, Joe Lane, met in Seattle, and negotiations commenced for the construction of a Jafco store on the Auto Vue property. Following a series of meetings in Seattle and Spokane, Mr. Lane wrote a letter to Mr. Nimmer on August 3, outlining three separate proposals for the development of the Auto Vue property. The letter provided in part:
Proposal A. We will lease the ground under the building (noted as Proposal A on the drawing) for $30,000 per year. We would like the right to install the parking lot in front at our expense and to have mutual cross-easements between the balance of the property and ours.
Proposal B. We will lease your entire property for $75,000 per year.
Proposal C. We will lease the Jafco property for $30,000 per year. We would joint venture the development of the balance of the property with you. . . .
In early September, Mr. Nimmer met with his attorney and his accountant to discuss the Lane proposals. He then wrote a letter to Mr. Lane expressing his general interest in proposal A, but suggested a 30-year lease term at $45,000 per year, subject to a 30 percent escalation every 5 years, and two 10-year options.
Mr. Nimmer and Mr. Lane met again in Seattle on September 15 to discuss the terms of the ground lease. Later that day, Mr. Lane prepared a letter for Mr. Nimmer pro
