Assignment task: Marshall works for Revamp Inc., a corporation that manufactures wooden furniture. Marshall is a procurement officer, responsible for purchasing raw materials that will be converted in to the furniture. As the main point of contact for suppliers, Marshall has built a relationship with many of them. Marshall routinely negotiates purchase contracts back and forth by e-mail. Marshall's e-mail signature includes his title and the company name under yourhis name. When it is time to finalize a contract, ReVamp is the name of the party to the contract, and Marshall signs his name on a line above his typed name, title, and company name. A friend of Marshall's, who has a little knowledge of contract law, asks how he can possibly sign his name to the contract without including the term "as agent for ReVamp." Explain how Marshall can avoid personal liability on the contracts even without adding this phrase.
