                  Intercreditor Agreement), regardless of (a) when KBK's

                  of the Purchased Accounts, (d) the consideration given or
                  promised for the Purchased Accounts, or (e) the amount
                  Creditor is owed by AESP. Lender agrees to file amendments to
                  Lender's financing statements evidencing such release of
                  collateral. Notwithstanding any other provision of this Loan
