WHEREAS, the Borrower has further advised the Lenders that it is possible that the Note Offering may close prior to the consummation of the Proposed Acquisition and, in that case, the Borrower wishes to deposit the proceeds of the Note Offering (together with certain other sums that would be sufficient to redeem the notes offered in the Note Offering if the Proposed Acquisition does not occur by a certain date) into an escrow account (a “Note Escrow Account”), with the understanding that (a) if the Proposed Acquisition should close on or prior to a certain date, the amounts in the Note Escrow Account shall be released to pay a portion of the purchase price of the Proposed Acquisition (concurrent with the payment and satisfaction in full of the Obligations) and certain transaction expenses and fees incurred in connection with the Note Offering, and (b) if the Proposed Acquisition shall not be consummated by such certain date, the amounts in the Note Escrow Account shall be used to redeem the notes issued pursuant to the Note Offering; and
