No material changes to such information have occurred since the initial Rule 424 filing. **Item 1122 of Regulation AB.     Compliance with Applicable Servicing Criteria**The assessment of compliance of Litton Loan Servicing LP ("Litton") has disclosed material noncompliance with criteria 1122(d)(2)(vii)(D) and 1122(d)(4)(ix). Certain investor bank account reconciliations included certain reconciling items that were not resolved within 90 calendar days of their original identification on eleven of sixty-three investor bank account reconciliations.  The sum of the reconciling items for those eleven reconciliations was $216,950.  Also, among a sample of sixty-five adjustable rate mortgages there were two instances where certain adjustable rate mortgages for which the interest rate reset in the servicing system did not agree to  interest rates in the appropriate source index per the borrowers note documents.  These were the result of incorrect information transferring from the prior servicer.  Additionally, the same  sixty-five mortgages included one instance where the adjustable rate mortgage payment change date in the servicing system did not agree to the loan documents.      See Item 15, exhibit 33 and 34.**********Item 1123 of Regulation AB.    Servicer Compliance Statement.**See Item 15, exhibit (35). ******PART IV****Item 15.
