APPENDIX B

**1.   Material Instances of Noncompliance by the Asserting Party**

The following instances of non-compliance by the Asserting Party have been identified with respect to the following provisions of Regulation AB Item 1122(d):

a.  Item 1122(d)(2)(vii)(D).  One reconciling item was not resolved within 90 days of its original identification.  This reconciling item was resolved within 124 days of its originalidentification and processes and procedures are in place to provide for on-going compliance with this requirement; and

b.  Item 1122(d)(3)(ii).  Prepayment fees due to investors in 16 or more securitizations subject to Reg AB were calculated incorrectly on certain loans with deferred interest, resulting in ashortfall in the distributions to those investors in an aggregate amount that is not expected to exceed  $1,500,000, of which not more than  $1,000,000 is expected to be attributable to incorrect calculations performed by the Asserting Party and not morethan  $500,000 is expected to be attributable to incorrect calculations performed by Washington Mutual Bank, an affiliate of the Asserting Party.    The amounts due as the result of these miscalculations will be delivered to the applicable Trusteefor distribution to the affected investors once analysis of the matter has been completed and the amounts due in the case of each securitization have been determined.  Processes and procedures have been implemented and are currently being validated to providefor more accurate calculation of prepayment fees.

c.  Item 1122(d)(3)(ii).   Certain LIBOR values were incorrectly determined for the December, 2007 distribution with respect to certain classes of securities subject to pooling andservicing agreements which requires that LIBOR values be determined on the second day on which banks in London are open for foreign exchange transactions prior to the 25th day of the prior calendar month.  In the referenced month, the specified LIBOR valuationday was Thanksgiving Day, not a day in the United States of America in which banks are open for transactions in foreign exchange but a day on which banks in London are.  LIBOR was established on the day immediately preceding Thanksgiving Day rather thanThanksgiving Day as required under the applicable pooling and servicing agreements.  The difference in LIBOR values was .00562 percentage points.  Accordingly certain classes of securities were overpaid interest and certain classes of securities wereunderpaid interest by the same amount.  In December, 2007, interest was reallocated to investors using the correct LIBOR values and total interest reallocated in each affected series of securities ranged from approximately $304 to $3,050.  The aggregateoriginal interest payments distributed to the affected series of securities ranged from approximately $1,124,821 to $11,126,217.  Procedures have been implemented to provide for accurate determinations of LIBOR.
