If a person negotiates or delivers a document of title for value, otherwise than as a mere intermediary under § 57A-7-508, unless otherwise agreed, the transferor warrants to its immediate purchaser only in addition to any warranty made in selling or leasing the goods that:
(1) The document is genuine;
(2) The transferor does not have knowledge of any fact that would impair the document's validity or worth; and
(3) The negotiation or delivery is rightful and fully effective with respect to the title to the document and the goods it represents.
