Warranties on Negotiation or Transfer of Receipt or Bill.

If a person negotiates or transfers a document of title for

value, otherwise than as a mere intermediary under Section 7-508 of

this title, unless otherwise agreed, the transferor, in addition to

any warranty made in selling or leasing the goods, warrants to its

immediate purchaser only 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 transfer is rightful and fully effective

with respect to the title to the document and the goods it

represents.
