Credit Accommodation Amount, Borrower shall, within five (5) Business Days,
either (i) furnish additional Collateral to Lender, in form and amount
satisfactory to Lender and Ex-Im Bank or (ii) pay to Lender an amount equal to
the difference between the Credit Accommodation Amount and the Export-Related
Borrowing Base.

              (b) For purposes of this Agreement, in determining the
         Export-Related Borrowing Base there shall be deducted from the

         (100%) of the face amount of Warranty Letters of Credit less the amount
         of cash collateral held by Lender to secure Warranty Letters of Credit.

         (60%) of the sum of the total outstanding principal balance of the
         Disbursements and the undrawn face amount of all outstanding Commercial
         Letters of Credit. If informed by Lender or if Borrower otherwise has
         actual knowledge that the outstanding principal balance of the Credit
         Accommodations that is supported by Inventory exceeds sixty percent
         (60%) of the sum of the total outstanding principal balance of the
         Disbursements and the undrawn face amount of all outstanding Commercial
         Letters of Credit, Borrower shall, within five (5) Business Days,
         either (i) furnish additional non-Inventory Collateral to Lender, in
         form and amount satisfactory to Lender and Ex-Im Bank, or (ii) pay down

Material Adverse Effect.

event within five (5) Business Days, notify Lender in writing of the occurrence
of any of the following:

              (a) Borrower or any Guarantor (i) applies for, consents to or

         Loan Documents to be granted to Lender, ceases to be a valid,

satisfaction of Loan Facility Obligations in accordance with the terms of any
agreement between Lender and Ex-Im Bank.
