A person who for value negotiates or transfers a document of title by indorsement or delivery, including one who assigns for value a claim secured by a document of title unless a contrary intention appears, warrants:
(1) That the document is genuine;
(2) That he has a legal right to negotiate or transfer it;
(3) That he has knowledge of no fact which would impair the validity or worth of the document; and
(4) That he has a right to transfer the title to the goods and that the goods are merchantable or fit for a particular purpose, whenever such warranties would have been implied if the contract of the parties had been to transfer without a document of title the goods represented thereby. (n)
