      principal amount will be due in twenty-four (24) regular monthly payments of

      payment, the first on March 28, 2008, and all subsequent payments are due on
      the
      same day of each month thereafter.  The final payment will be due on
      February 28, 2010, and will for all principal and all accrued interest not
      yet
      paid, together will all unpaid amounts under this Note.  Pay are
      interest-only until such time the principal balance is reduced.  In
      the event the principal balance is reduced, payments will remain the same
      monthly amount and will include both principal and interest.  Unless
