Agent will pay to each Revolving Loan Lender such Lender's Revolving Loan Commitment Percentage of all amounts received from Borrower for application in payment, in whole or in part, of the Reimbursement Obligation in respect of any Letter of Credit, but only to the extent such Lender has made payment to Agent in respect of such Letter of Credit pursuant to CLAUSE (III) above.

To the extent that such prepayment arises out of an event occurring with respect to Property which does not constitute "current assets", the Stationary Term Loan Balance shall automatically be reduced by the amount of such prepayment. (ii) In cases where the amount of the net cash proceeds of any payment or award is equal to or less than $50,000 and no Default or Event of Default has occurred and is continuing, such proceeds may be paid to any Obligor, and if received by Agent shall be paid by Agent to Borrower, for use in paying for replacements or repairs of or substitutes for the damaged, destroyed or taken assets or in a manner otherwise consistent with this Agreement.
