         itself, that, in connection with such sale, (i) no Seller made, and no
         Seller will make, representations or warranties in connection with such
         sale of Subject Receivables, (ii) both before and after giving effect
         to such sale, no Amortization Event or Potential Amortization Event
         exists, (iii) the purchaser of the Subject Receivables has no, and will
         have no, recourse to any Seller or the assets of any Seller (other than

         such sale, the aggregate Outstanding Balance of all Subject Receivables
         is estimated to be $275,000, which amount is subject to post-closing
         adjustment which post-closing adjustment shall be completed by August

         fair consideration for, and reflects an arm's length sale of, such
         Subject Receivables, (vi) the Subject Receivables have not been

         sale will continue to be, readily identifiable and distinguishable from
         all other Receivables and all Collections and Related Security with

         hereto agrees that the purchase price paid upon the sale of the Subject
