§12A-9-206.
   
   Agreement Not to Assert Defenses Against Assignee; Modification of
   Sales Warranties Where Security Agreement Exists.
   
   (1) Subject to any statute or decision which establishes a different
   rule for buyers or lessees of consumer goods, an agreement by a buyer
   or lessee that he will not assert against an assignee any claim or
   defense which he may have against the seller or lessor is enforceable
   by an assignee who takes his assignment for value, in good faith and
   without notice of a claim or defense, except as to defenses of a type
   which may be asserted against a holder in due course of a negotiable
   instrument under the article on Negotiable Instruments (Article 3). A
   buyer who as part of one transaction signs both a negotiable
   instrument and a security agreement makes such an agreement.
   
   (2) When a seller retains a purchase money security interest in goods
   the Article on Sales (Article 2) governs the sale and any disclaimer,
   limitation or modification of the seller's warranties.
