business day and such extension of time shall be included in the computation of
the payment of interest on this Note.

      Each payment received by the Lender shall be applied first, against all
costs and expenses of the Lender incurred in connection with this Note, second,
against accrued and unpaid interest on the outstanding principal balance of this
Note, and third, the balance of each such payment shall be applied against the
principal hereof.

of principal or interest pursuant to this Note, (ii) the Borrower is dissolved,
becomes insolvent under any law, suspends its present business, or agrees to a
merger, bulk sale or transfer of all or substantially all of its assets, (iii)

proceeding or has a trustee or receiver appointed for it or its assets, or (iv)

written notice thereof to the Borrower; provided, however, that, upon the
occurrence of an event specified in clauses (i), (ii) or (iii) above, no notice
shall be required. Immediately upon the occurrence of an event specified in
clauses (i), (ii) or (iii) above, or immediately upon the Lender giving the

the fullest extent permitted by law, the right to plead any statute of

constitute a waiver hereof in that or any subsequent instance.

      This Note may not be changed or terminated orally. This Note shall bind
the successors and assigns of the undersigned and shall enure to the benefit of
the Lender and his heirs, legal representatives, successors and assigns.

      Each provision of this Note shall survive until all amounts due are paid
