§12A-3-407.
   
                                 ALTERATION
                                      
   (a) "Alteration" means (i) an unauthorized change in an instrument
   that purports to modify in any respect the obligation of a party, or
   (ii) an unauthorized addition of words or numbers or other change to
   an incomplete instrument relating to the obligation of a party.
   
   (b) Except as provided in subsection (c) of this section, an
   alteration fraudulently made discharges a party whose obligation is
   affected by the alteration unless that party assents or is precluded
   from asserting the alteration. No other alteration discharges a party,
   and the instrument may be enforced according to its original terms.
   
   (c) A payor bank or drawee paying a fraudulently altered instrument or
   a person taking it for value, in good faith and without notice of the
   alteration, may enforce rights with respect to the instrument (i)
   according to its original terms, or (ii) in the case of an incomplete
   instrument altered by unauthorized completion, according to its terms
   as completed.
