________________________________

[1] No transaction agreements require the Asserting Party to maintain a back-up servicer.

[2] The Asserting Party perfoms the servicing functions described in Items 1122(d)(3)(i)(A) and (B).  With regard to section (D) of criteria (3)(i), it is not theAsserting Party’s practice to regularly tie-out balances to investors’ or trustee’s records.  Loan counts and balances are periodically reconciled upon request by a master servicer. 

[3] The Asserting Party does not perform the servicing function described in Item 1122(d)(3)(i)(C).

**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). Approximately 532 account reconciliations out of approximately 60,000 statements (or approximately 0.9%) with reconciling items were not resolved within 90 days of theiridentification, due to the migration of functions to personnel in a separate geographic location.  All such reconciling items have been resolved in the meantime and processes and procedures are in place to provide for on-going compliance with thisrequirement;

b.  Item 1122(d)(3)(i)(B) and (3)(ii). A programming change resulted in the miscalculation of some liquidation proceeds and the failure to include other liquidation proceeds, in the aggregate amountof approximately $9,694,614, in the September 2007 distribution with respect to 13 securitizations subject to Regulation AB.  The servicer in each of the securitizations remitted the applicable shortfall amount on October 1, 2007 to the applicable Trustee asrequired by the applicable pooling and servicing agreement.  The programming error was corrected in October 2007;

c.  Item 1122(d)(3)(ii).  Prepayment fees due to investors in 16 or more securitizations subject to Regulation AB were calculated incorrectly on certain loans with deferred interest, resultingin a shortfall in the distributions to those investors in an aggregate amount that is not expected to exceed $500,000.  In addition, the servicer has determined that under certain circumstances, the servicer's automated loan servicing system calculates theapplicable interest to be used to determine prepayment premiums inconsistently with the requirements of certain mortgage loan notes, which could result in the underpayment of prepayment premiums due to certificateholders in prepayment premium classes under the termsof the applicable transaction agreements. Approximately 15 loans in 8 securitizations subject to Regulation AB have been identified that may have been affected in 2007. Any amounts due as the result of these miscalculations will be delivered to the applicable Trusteefor distribution to the affected investors once analysis of these matters has been completed and the amounts due in the case of each securitization have been determined.   Processes and procedures are currently being implemented to provide for more accuratecalculation of prepayment fees and the servicer is making changes to its automated servicing system to provide for some of the identified variations in the terms of mortgage note prepayment requirements;

d.  Item 1122(d)(4)(vii). With respect to 4 series of mortgage-backed securities, the servicer recently self-identified foreclosure cases initiated in connection with approximately 175 loans wherethe servicer did not expressly disclose the interests in the loans of the applicable trustees.  To the extent necessary under applicable law and court rules, the servicer will promptly move to amend those foreclosure pleadings.  Investors will be made wholeif any direct losses or additional costs and expenses are incurred as a result of the failure to identify the interests of the trusts in the loans in any proceeding in which applicable law or court rules the trusts’ interests must be disclosed.  Theservicer will conduct further research and if additional loans are identified that were treated similarly, the servicer will make the applicable trusts whole if any losses arise from such treatment; and

e.  Item 1122(d)(4)(xiv).  Delinquent second lien mortgage loans were not charged off at 180 days as required by the applicable pooling and servicing agreements in the case of twosecuritizations subject to Reg AB.  All such mortgage loans were charged off as required upon identification of the non-compliance.  Processes and procedures have been put in place to provide for on-going compliance with this requirement.
