Guyan Machinery, a West Virginia manufacturing corporation, hired Albert Voorhees as a salesman and required him to sign a contract stating that if he left Guyan, he would not work for a competing corporation anywhere within 250 miles of West Virginia for a two-year period. Later, Voorhees left Guyan and began working at Polydeck Corp., another West Virginia manufacturer. The only product Polydeck made was urethane screens, which comprised half of 1% of Guyan's business. Is Guyan entitled to enforce its non-compete clause?
