Without limiting the generality of the foregoing, it is understood and agreed that if the Loans are accelerated or otherwise become due prior to their maturity date, in each case, in respect of any Event of Default (including upon the occurrence of a bankruptcy or insolvency event (including the acceleration of claims by operation of law)), the Prepayment Premium applicable with respect to a voluntary prepayment of the Loans will also be due and payable on the date of such acceleration or such other prior due date as though the Loans were voluntarily prepaid as of such date and shall constitute part of the Obligations, in view of the impracticability and extreme difficulty of ascertaining actual damages and by mutual agreement of the parties as to a reasonable calculation of each Lender’s loss as a result thereof. Any premium payable above shall be presumed to be the liquidated damages sustained by each Lender and the Borrower agrees that it is reasonable under the circumstances currently existing. THE BORROWER EXPRESSLY WAIVES (TO THE FULLEST EXTENT IT MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE PREPAYMENT PREMIUM IN CONNECTION WITH ANY SUCH ACCELERATION. The Borrower expressly agrees (to the fullest extent it may lawfully do so) that: (A) the Prepayment Premium is reasonable and is the product of an arm’s length transaction between sophisticated business people, ably represented by counsel; (B) the Prepayment Premium shall be payable notwithstanding the then prevailing market rates at the time payment is made; (C) there has been a course of conduct between the Lenders and the Borrower giving specific consideration in this transaction for such agreement to pay the Prepayment Premium; and (D) the Borrower shall be estopped hereafter from claiming differently than as agreed to in this paragraph.”
