Servicer Compliance Statement

1. I, Xxxx X. Xxxxx, Senior Vice President of Xxxxx Fargo Bank, N.A. ("Xxxxx Fargo")
hereby state that a review of the activities of Xxxxx Fargo during the calendar year 2006
and of Xxxxx Fargo's performance under the servicing agreement(s) listed on the attached
Exhibit A (the "Servicing Agreement(s)") has been made under my supervision.

2. To the best of my knowledge, based on such review, Xxxxx Fargo has fulfilled all of its
obligations under the Servicing Agreement(s) in all material respects throughout 2006,
with the exception of the following failure(s) to fulfill any such obligation in any material
respect:

For certain loans sub-serviced by Xxxxx Fargo or for which servicing rights were acquired
on a bulk-acquisition basis, Xxxxx Fargo determined that it provided incomplete data to
some third parties who use such data to calculate delinquency ratios and the status of
loans with respect to bankruptcy, foreclosure or real estate owned. The incomplete
reporting only affected securitizations that included delinquent loans. Instead of the
actual due date being provided for use in calculating delinquencies, the date of the first
payment due to the security was provided. Xxxxx Fargo subsequently included additional
data in monthly remittance reports, providing the actual borrower due date and unpaid
principal balance, together with instructions to use these new fields if such monthly
remittance reports are used to calculate delinquency ratios.
