Management's Report on Assessment of Compliance with Applicable Servicing
Criteria

Chase Home Finance LLC (the "Asserting Party") is responsible for assessing
compliance as of December 31, 2006 and for the period from January 1, 2006
through December 31, 2006 (the "Reporting Period"), with the servicing criteria
set forth in Title 17, Section 229.1122(d) of the Code of Federal Regulations
(the "CFR"), excluding the inapplicable servicing criteria as set forth in
Exhibit A hereto (such criteria, after giving effect to the exclusions
identified on Exhibit A, the "Applicable Servicing Criteria"). This report
covers the asset-backed securities transactions backed by subprime residential
mortgages serviced on the Loan Servicing and Accounting Management System I
("LSAMS I") where the related asset-backed securities were outstanding during
the Reporting Period (the "Platform").

The Asserting Party has engaged certain vendors (the "Vendors") to perform
specific and limited activities or activities scripted by the Asserting Party as
of and during the Reporting Period, and the Asserting Party elects to take
responsibility for assessing compliance with the Applicable Servicing Criteria
or portion of the servicing criteria applicable to such Vendors as set forth in
Exhibit A hereto (such criteria, the "Applicable Vendor Servicing Criteria").

The Asserting Party (i) has not identified and is not aware of any material
instance of noncompliance by the Vendors with the Applicable Vendor Servicing
Criteria and (ii) has not identified any material deficiency in its policies and
procedures to monitor the compliance by the Vendors with the Applicable Vendor
Servicing Criteria as of December 31, 2006 and for the Reporting Period.

The Asserting Party (i) has used the criteria set forth in 17 CFR 229.1122(d) to
assess the compliance by the Asserting Party with the Applicable Servicing
Criteria for the Reporting Period and (ii) has concluded that the Asserting
Party has complied, in all material respects, with the Applicable Servicing
Criteria as of December 31, 2006 and for the Reporting Period with respect to
the Platform, taken as a whole.

PricewaterhouseCoopers LLP, an independent registered public accounting firm,
has issued an attestation report for the Platform on our assessment of
compliance with the Applicable Servicing Criteria as of December 31, 2006 and
for the Reporting Period as set forth in this report.

Report of Independent Registered Public Accounting Firm

To the Stockholder of Chase Home Finance LLC:


We have examined management's assertion, included in the accompanying
Management's Report on Assessment of Compliance with Applicable Servicing
Criteria, that Chase Home Finance LLC (the "Company") complied with the
servicing criteria set forth in Item 1122(d) of the Securities and Exchange
Commission's Regulation AB, as of and for the year ended December 31, 2006 (the
"Reporting Period"), for asset backed securities transactions backed by subprime
residential mortgages serviced on the Loan Servicing and Accounting Management
System I ("LSAMS I") where the related asset-backed securities were outstanding
during the Reporting Period (the "Platform"), excluding criteria
1122(d)(1)(iii), 1122(d)(4)(i), 1122(d)(4)(ii) and 1122(d)(4)(xv), which the
Company has determined are not applicable to the activities performed by it with
respect to the Platform. Management is responsible for the Company's compliance
with the servicing criteria. Our responsibility is to express an opinion on
management's assertion based on our examination.

Our examination was conducted in accordance with standards of the Public Company
Accounting Oversight Board (United States) and, accordingly, included examining,
on a test basis, evidence about the Company's compliance with the applicable
servicing criteria and performing such other procedures as we considered
necessary in the circumstances. Our examination included testing of selected
asset-backed transactions and securities that comprise the Platform, testing of
selected servicing activities related to the Platform, and determining whether
the Company processed those selected transactions and performed those selected
activities in compliance with the applicable servicing criteria. Our procedures
were limited to the selected transactions and servicing activities performed by
the Company during the period covered by this report. Our procedures were not
designed to detect noncompliance arising from errors that may have occurred
prior to or subsequent to our tests that may have affected the balances or
amounts calculated or reported by the Company during the period covered by this
report. We believe that our examination provides a reasonable basis for our
opinion. Our examination does not provide a legal determination on the Company's
compliance with the servicing criteria.

In our opinion, management's assertion that the Company complied with the
aforementioned applicable servicing criteria as of and for the year ended
December 31, 2006 for the for asset-backed securities transactions backed by
subprime residential mortgages serviced on the LSAMS I where the related
asset-backed securities were outstanding during the Reporting Period is fairly
stated, in all material respects.

1122(d)(4)(xii) and 1122(d)(4)(xiii), which the Company has determined are not
applicable to the activities it performs with respect to the Platform, as of and
for the twelve months ended December 31, 2006. Management is responsible for the
Company's compliance with those servicing criteria. Our responsibility is to
express an opinion on management's assertion about the Company's compliance
based on our examination.

Our examination was conducted in accordance with the standards of the Public
Company Accounting Oversight Board (United States) and, accordingly, included
examining, on a test basis, evidence about the Company's compliance with the
servicing criteria specified above and performing such other procedures as we
considered necessary in the circumstances. Our examination included testing of
less than all of the individual asset-backed transactions and securities that
comprise the Platform, testing of less than all of the servicing activities
related to the Platform, and determining whether the Company processed those
selected transactions and performed those selected activities in compliance with
the servicing criteria. Furthermore, our procedures were limited to the selected
transactions and servicing activities performed by the Company during the period
covered by this report. Our procedures were not designed to determine whether
errors may have occurred either prior to or subsequent to our tests that may
have affected the balances or amounts calculated or reported by the Company
during the period covered by this report for the selected transactions or any
other transactions. We believe that our examination provides a reasonable basis
for our opinion. Our examination does not provide a legal determination on the
Company's compliance with the servicing criteria.

As described in the accompanying management's Assessment of Compliance With
Applicable Servicing Criteria, for servicing criteria 1122(d)(4)(i), the Company
has engaged various vendors to perform the activities required by these
servicing criteria. The Company has determined that these vendors are not
considered a "servicer" as defined in Item 1101(j) of Regulation AB, and the
Company has elected to take responsibility for assessing compliance with the
servicing criteria applicable to each vendor as permitted by Interpretation
17.06 of the SEC Division of Corporation Finance Manual of Publicly Available
Telephone Interpretations ("Interpretation 17.06"). As permitted by
Interpretation 17.06, the Company has asserted that it has policies and

procedures in place designed to provide assurance that the vendors' activities
comply in all material respects with the servicing criteria applicable to each
vendor. The Company is solely responsible for determining that it meets the SEC
requirements to apply Interpretation 17.06 for the vendors and related criteria
as described in its assertion, and we performed no procedures with respect to
the Company's eligibility to apply Interpretation 17.06.

Our examination disclosed material noncompliance with criterion 1122(d)(3)(i),
as applicable to the Company during the twelve months ended December 31, 2006.
Certain monthly investor or remittance reports included errors in the
calculation and/or the reporting of delinquencies for the pool assets.

In our opinion, except for the material non-compliance described above, the
Company complied, in all material respects, with the aforementioned servicing
criteria, including servicing criteria for which compliance is determined based
on Interpretation 17.06 as discussed above, as of and for the twelve months
ended December 31, 2006.

The Corporate Trust Services division of Wells Fargo Bank, National Association:

We have examined the compliance of the Corporate Trust Services division of
Wells Fargo Bank, National Association (the Company) with the servicing criteria
set forth in Item 1122(d) of the Securities and Exchange Commission's Regulation
AB for publicly-issued (i.e., transaction-level reporting initially required
under the Securities Exchange Act of 1934, as amended) residential
mortgage-backed securities, commercial mortgage-backed securities and other
asset-backed securities, for which the Company provides master servicing,
trustee, securities administration or paying agent services, excluding
transactions issued by any agency or instrumentality of the U.S. government or
any government sponsored entity (the Platform), except for servicing criteria

Report of Independent Registered Public Accounting Firm

The Board of Directors
The Corporate Trust Services division of Wells Fargo Bank National Association:

We have examined management's assertion, included in the accompanying Appendix
I, that the Document Custody section of the Corporate Trust Services division of
Wells Fargo Bank National Association complied with the servicing criteria set
forth in Item 1122(d) of the Securities and Exchange Commission's Regulation AB
for publicly-issued (i.e., transaction-level reporting required under the
Securities Exchange Act of 1934, as amended) residential mortgage-backed
securities and commercial mortgage-backed securities issued on or after January
1, 2006 for which the Company provides document custody services, excluding any
publicly issued transactions issued by any government sponsored entity (the
Platform) as of and for the twelve months ended December 31, 2006. Management
has determined that servicing criteria 1122(d)(4)(i) and 1122(d)(4)(ii) are
applicable to the activities it performs with respect to the Platform, and that
all other servicing criteria set forth in Item 1122(d) are not applicable to the
document custody services provided by the Company with respect to the Platform.
Management is responsible for the Company's compliance with those servicing
criteria. Our responsibility is to express an opinion on management's assertion
about the Company's compliance based on our examination.

Our examination was conducted in accordance with the standards of the Public
Company Accounting Oversight Board (United States) and, accordingly, included
examining, on a test basis, evidence about the Company's compliance with the
servicing criteria specified above and performing such other procedures as we
considered necessary in the circumstances. Our examination included testing of
less than all of the individual asset-backed transactions and securities that
comprise the Platform, testing of less than all of the servicing activities
related to the Platform, and determining whether the Company processed those
selected transactions and performed those selected activities in compliance with
the servicing criteria. Furthermore, our procedures were limited to the selected
transactions and servicing activities performed by the Company during the period
covered by this report. Our procedures were not designed to determine whether
errors may have occurred either prior to or subsequent to our tests that may
have affected the balances or amounts calculated or reported by the Company
during the period covered by this report for the selected transactions or any
other transactions. We believe that our examination provides a reasonable basis
for our opinion. Our examination does not provide a legal determination on the
Company's compliance with the servicing criteria.

In our opinion, management's assertion that the Company complied with the
aforementioned servicing criteria as of and for the period ended December 31,
2006 is fairly stated, in all material respects.
