     For Wachovia Bank, National Association, a master servicer for the DDR
     Portfolio loan, the report on assessment of compliance and attestation
     report attached hereto under Item 15 describe the following instances
     of material noncompliance:

     With respect to servicing criterion 1122(d)(2)(i), certain payments on
     pool assets were not deposited into the appropriate custodial bank account
     within the timeframe as specified in the transaction agreement.  Those
     payments were deposited into the appropriate custodial bank accounts after
     those timeframes.  Management does not believe that this failure to follow
     the transaction agreements result in any loss of control over trust assets
     or in any impact to investors.  Wachovia Bank, National Association
     implemented additional controls in 2008 to better monitor these processes
     and correct the non-compliance.

     With respect to servicing criterion 1122(d)(2)(ii), certain disbursements
     made via wire transfer were authorized by personnel for amounts greater
     than such personnel's approval limits.  Management does not believe that
     this failure to follow internal procedures resulted in any incorrect wire
     transfers or in any impact to investors.  Wachovia Bank, National
     Association implemented additional controls in 2007 to better monitor
     these processes and correct the non-compliance.
