and each payment made on account of the principal thereof, shall be recorded by
the Lender on its books and, prior to any transfer of the Revolving Loan Note,
endorsed by the Lender on the schedule attached to the Revolving Loan Note or
any continuation thereof; provided that the failure of the Lender to make any
such recordation or endorsement shall not affect the obligations of the Borrower
to make a payment when due of any amount owing hereunder or under the Revolving
Loan Note in respect of the Loans.

     Section 2.3 Procedure for Borrowing.

     (a) The Borrower may request a borrowing hereunder, on any Business Day

maturity, by acceleration or by mandatory prepayment or otherwise), for the
period from and including the due date thereof to but excluding the date the
same is paid in full (both before and after judgment). Any payment due and owing
at the Post-Default Rate shall be payable on demand by the Lender.

interest then to the payment of outstanding principal until paid in full.
Amounts prepaid may be re-borrowed in accordance with the terms of this
Agreement.

     Section 2.6 Indemnity. Upon demand by the Lender, the Borrower agrees to
indemnify the Lender and to hold the Lender harmless from any net loss or
expense (not to include any lost profit or opportunity) which the Lender may
sustain or incur as a consequence of default by the Borrower in making any
payments due under this Agreement.

basis of a 365-day year and the actual number of days elapsed in any interest

condition or operations of the Borrower and such material adverse change remains
unremedied for 14 days thereafter; or
