 The

 Item 1122 of Regulation AB.
Compliance with Applicable Servicing Criteria.
 See Item
15, exhibits (33) and (34).
  The
following information regarding LaSalle Bank National Association's material
instances of noncompliance and related remedial action was provided by LaSalle
Bank National Association.
  LaSalle
Bank National Association’s (“LaSalle”) Report on Assessment of Compliance with
Servicing Criteria for 2007 (the “2007 Assessment”) attached to this Report on
Form 10-K describes in Appendix B the following material instance of
noncompliance related to investor reporting:
 
 “1122(d)(3)(i)(A)
and (B) – During the Reporting Period, certain monthly investor or remittance
reports were not prepared in accordance with the terms set forth in the
transaction agreements and certain investor reports did not provide the
information calculated in accordance with the terms specified in the transaction
agreements for which certain individual errors may or may not have been
material.”
 
 The
investor reporting errors identified on LaSalle’s 2007 Assessment as material
instances of noncompliance (the “Investor Reporting Errors”) included, for
example, revised delinquency, REO, foreclosure, repurchase, payoff or modified
loan counts, category indicators and/or balances.  The conclusion that
the Investor Reporting Errors amounted to a material instance of noncompliance
was based primarily on the aggregate number of errors as opposed to the
materiality of any one error.
 
 The
Investor Reporting Errors were generally caused by human error resulting
primarily from high volume monthly data processing demands that had to be
addressed within constricted time frames with less than a full complement of
operational staff.  Between the fourth quarter of the Reporting Period
and the date of the 2007 Assessment, LaSalle has employed additional operational
staff to accommodate the high volume of monthly investor reporting requirements
and minimize the risk of the Investor Reporting Errors
recurring.  Other necessary controls are in place to minimize the risk
of such errors.
 
 With
respect to the specific pool assets and asset-backed securities related to the
Investor Reporting Errors, the errors did not have, and are not reasonable
likely in the future to have, any material impact or effect on pool asset
performance, servicing of the pool assets and payments or expected payments on
the mortgage-backed securities.




The
Certification Regarding Compliance with Applicable Servicing Criteria of Home
Loan Services, Inc. (the “HLS Certification”) identified material instances of
noncompliance with respect to the following servicing criteria:
 
 Item 1122
(d)(1)(i) – Policies and procedures instituted to monitor any performance or
other triggers and events of default in accordance with the transaction
agreements.
 
 Item
1122(d)(2)(vii) – Monthly reconciliations for all asset-backed securities
related bank accounts, including custodial accounts and related bank clearing
accounts. Such reconciliations are prepared within 30 calendar days after the
bank statement cutoff date, or such other number of days specified in the
transaction agreements.
 
 Item
1122(d)(4)(x)(c) – Funds held in trust for an obligor (such as escrow accounts),
which are returned to the obligor within 30 calendar days of full repayment of
the related pool asset, or such other number of days specified in the
transaction agreements.
 
 The HLS
Certification stated that the following remediation efforts have been made with
respect to such material instances of noncompliance:
 
 Item 1122
(d)(1)(i) – “Monthly reporting and quarterly review processes were established
in April 2007 and maintained throughout the remainder of the year. No subsequent
exceptions were noted.”
 
 Item
1122(d)(2)(vii) – “Bank reconciliations were completed within the 30 day period;
however, preparers sign-off did no occur until the 31st day.
This exception was noted in the first six months of 2007. Processes were revised
with no subsequent findings in the second half of 2007.”
 
 Item
1122(d)(4)(x)(c) – “Funds held in escrow on two accounts were not returned
within 30 days of loan payoff. Processes have been revised to ensure for future
compliance.”
 
 The
Report on Assessment of Compliance of American Security Insurance Company,
Standard Guaranty Insurance Company and TrackSure Insurance Agency, Inc. (the
relevant Vendor cited in the HLS Certification) indicated a material instance of
noncompliance with Item 1122(d)(4)(xii), and stated that the company “did not
have, during the Reporting Period, sufficient policies and procedures to capture
the information with respect to the Platform Transactions necessary to determine
compliance with Item 1122(d)(4)(xii).”
 
 The HLS
Certification stated that the Vendor has made the following remediation efforts
with respect to such material instance of noncompliance:
 
 Item
1122(d)(4)(xii) – “Practices and procedures to capture information necessary to
assess compliance were implemented as of January 1, 2008 by Assurant Specialty
Property.”
 
 The HLS
Certification did not report any material deficiencies with respect to policies
and procedures in place to monitor Vendors.
 Item 1123 of Regulation AB. Servicer
Compliance Statement.
 See Item
15, exhibit (35).
  Although
the above-referenced material instances of noncompliance with respect to Items
1122(d)(1)(i), 1122(d)(2)(vii) and 1122(d)(4)(x)(c) in the HLS Certification
were material to the activities of Home Loan Services, Inc. ("HLS") on a
platform level, HLS indicated that such instances of noncompliance had no
material effect on the performance of HLS in its capacity as servicer under the
pooling and servicing agreement related to the securities issued by the Issuing
Entity. Accordingly, the servicer compliance statement of HLS was appropriately
unqualified.
