4-3-117.    Other agreements affecting instrument.
    Subject  to applicable law regarding exclusion of proof of contemporaneous or  previous agreements, the obligation of a party to an instrument to pay  the instrument may be modified, supplemented, or nullified by a separate  agreement of the obligor and a person entitled to enforce the  instrument, if the instrument is issued or the obligation is incurred in  reliance on the agreement or as part of the same transaction giving  rise to the agreement. To the extent an obligation is modified,  supplemented, or nullified by an agreement under this section, the  agreement is a defense to the obligation.
