§12A-3-112.
   
                                  INTEREST
                                      
   (a) Unless otherwise provided in the instrument, (i) an instrument is
   not payable with interest, and (ii) interest on an interest-bearing
   instrument is payable from the date of the instrument.
   
   (b) Interest may be stated in an instrument as a fixed or variable
   amount of money or it may be expressed as a fixed or variable rate or
   rates. The amount or rate of interest may be stated or described in
   the instrument in any manner and may require reference to information
   not contained in the instrument. If an instrument provides for
   interest, but the amount of interest payable cannot be ascertained
   from the description, interest is payable at the judgment rate in
   effect at the place of payment of the instrument and at the time
   interest first accrues.
