Borrower acknowledges and agrees that if on the effective date of such reduction of the Maximum Commitment the aggregate principal amount of the then outstanding Loans exceeds the Maximum Commitment (taking into account such reduction in the Tranche A Commitment), then no later than on such effective date Borrower shall repay the principal amount of Loans (together with accrued interest on such repaid principal amount) such that immediately thereafter the aggregate principal amount of Loans outstanding shall not be greater than the Maximum Commitment (with any such repayment being first applied to Tranche A Loans).”
