§12A-3-413.
   
                           OBLIGATION OF ACCEPTOR
                                      
   (a) The acceptor of a draft is obliged to pay the draft (i) according
   to its terms at the time it was accepted, even though the acceptance
   states that the draft is payable "as originally drawn" or equivalent
   terms, (ii) if the acceptance varies the terms of the draft, according
   to the terms of the draft as varied, or (iii) if the acceptance is of
   a draft that is an incomplete instrument, according to its terms when
   completed, to the extent stated in Sections 3-115 and 3-407 of this
   title. The obligation is owed to a person entitled to enforce the
   draft or to the drawer or an indorser who paid the draft under Section
   3-414 or 3-415 of this title.
   
   (b) If the certification of a check or other acceptance of a draft
   states the amount certified or accepted, the obligation of the
   acceptor is that amount. If (i) the certification or acceptance does
   not state an amount, (ii) the amount of the instrument is subsequently
   raised, and (iii) the instrument is then negotiated to a holder in due
   course, the obligation of the acceptor is the amount of the instrument
   at the time it was taken by the holder in due course.
