      annum until the first to occur of the Maturity Date or the date on which
      the entire principal balance hereof shall have been paid.

            1.3 Interest shall accrue and be payable on a calendar quarterly
      basis during such time as any portion of the principal amount of this
      Promissory Note shall be outstanding. Payments of interest shall be due
      and payable one calendar quarter in arrears, on or before the fifth day of
      each calendar month immediately following the expiration of any calendar
      quarter during which any portion of the principal amount of this

            1.4 If payment of the principal amount hereof and interest accrued
      thereon is not made on or before the Maturity Date, interest shall

      hereunder ("Event of Default"), provided that upon the occurrence of an
      event described in Subsections 3.1 or 3.2 such event shall be deemed to be
      an Event of Default hereunder whether or not the Payee makes such a
      declaration (an "Automatic Default"), and the indebtedness evidenced by
      this Promissory Note shall immediately upon such declaration or Automatic
      Default become due and payable, both as to principal and interest, without
      presentment, demand, protest or other notice of any kind, all of which are
      hereby expressly waived, notwithstanding anything contained herein to the
      contrary.

      4. If any one or more defaults shall occur and be continuing, Payee may
proceed to protect and enforce such Payee's rights either by suit in equity or
