Final answer:
The statement is false because in an exclusive dealing contract under the UCC, not only does the distributor have to use best efforts to sell the goods, but the supplier often has certain obligations to support the distributor's efforts as well.
Step-by-step explanation:
According to the provisions of the Uniform Commercial Code (UCC), the statement that an exclusive dealing contract imposes a duty only on the distributor to use his/her best efforts to sell the goods is false. Although the primary responsibility is on the distributor to make the best effort to sell the goods, the supplier or manufacturer also typically has a duty to provide reasonable support, such as marketing assistance or exclusive sales rights within a certain territory, to help ensure the distributor can effectively sell the products. These contracts can have implications for competition, as they may both promote competition among dealers when properly structured and limit competition if they create monopolistic environments when one dealer is given exclusive rights that are too broad or encompass multiple product lines.
