All prepayments of the Term Loan shall be made to the Agent for distribution ratably to the applicable Term Lenders in accordance with their Term Loan Percentages.

2A.8 Mandatory Prepayment of Term Loan.

(a) Subject to clauses (c) and (d) hereof, immediately upon receipt by any Loan Party of any Net Cash Proceeds from any Asset Sales or Condemnation Proceeds involving Net Cash Proceeds greater than $250,000 which are not Reinvested as described in the following sentence, Borrowers shall prepay the Term Loan by an amount equal to one hundred percent (100%) of such Net Cash Proceeds provided, however that Borrowers shall not be obligated to prepay the Term Loan with such Net Cash Proceeds if the following conditions are satisfied: (i) promptly following the Asset Sale or receipt of Condemnation Proceeds, as the case may be, Borrowers provide to Agent a certificate executed by a Responsible Officer of both Borrowers (“Reinvestment Certificate”) stating (x) that the sale or condemnation has occurred, (y) that no Default or Event of Default has occurred and is continuing either as of the date of the sale or as of the date of the Reinvestment Certificate, and (z) a description of the planned Reinvestment of the proceeds thereof, (ii) the Reinvestment of such Net Cash Proceeds is commenced within the Reinvestment Period and completed within the Reinvestment Period, and (iii) no Default or Event of Default has occurred and is continuing at the time of the sale and at the time of the application of such proceeds to Reinvestment. If any such proceeds have not been Reinvested at the end of the Reinvestment Period, Borrowers shall promptly pay such proceeds to Agent, to be applied to repay the Term Loan in accordance with clauses (c) and (d) hereof.

(c) Subject to clause (d) hereof, each mandatory prepayment under this Section 2A.8 or any other mandatory or optional prepayment under this Agreement shall be in addition to any scheduled installments or optional prepayments made prior thereto and shall be subject to Section 10.1. Each mandatory prepayment of the Term Loan shall be applied to installments of principal on the Term Loan in the inverse order of maturity.

(d) To the extent that, on the date any mandatory prepayment of the Term Loan under this Section 2A.8 is due, the Indebtedness under the Term Loan or any other Indebtedness to be prepaid is being carried, in whole or in part, at the Eurocurrency-based Rate and no Default or Event of Default has occurred and is continuing, Borrowers may deposit the amount of such mandatory prepayment in a cash collateral account to be held by the Agent, for and on behalf of the Banks (which shall be an interest-bearing account), on such terms and conditions as are reasonably acceptable to Agent and upon such deposit, the obligation of each Borrower to make such mandatory prepayment shall be deemed satisfied. Subject to the terms and conditions of said cash collateral account, sums on deposit in said cash collateral account shall be applied (until exhausted) to reduce the principal balance of the Term Loan on the last day of each Eurocurrency-Interest Period attributable to the Eurocurrency-based Advances of the Term Loan, thereby avoiding breakage costs under Section 10.1.
