Item 1122 of Regulation AB, Compliance with Applicable Servicing Criteria.

See Item 15, exhibits (33) and (34)

Wachovia Bank, National Association's ("Wachovia") Report on Assessment of
Compliance with Servicing Criteria for 2007 attached to this Report on Form
10-K describes the following material noncompliance with servicing criteria
1122(d)(2)(i) and 1122(d)(2)(ii):

          "With respect to servicing criterion 1122(d)(2)(i), certain
          payments on pool assets were not deposited into the
          appropriate custodial bank accounts within the timeframe as
          specified in the transaction agreements. Those payments were
          deposited into the appropriate custodial bank accounts after
          those timeframes. Management does not believe that this
          failure to follow the transaction agreement resulted in any
          loss of control over trust assets or in any impact to the
          investors. [Wachovia] 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]
          implemented additional controls in 2007 to better monitor
          these processes and correct the non-compliance."
