Wells Fargo Bank, N.A.

ASSESSMENT OF COMPLIANCE WITH APPLICABLE SERVICING CRITERIA

Corporate Trust Services division of Wells Fargo Bank, National Association (the
"Company") provides this assessment of compliance with the following applicable
servicing criteria set forth in Item 1122(d) of Regulation AB promulgated by
the Securities and Exchange Commission. Management has determined that the
servicing criteria are applicable in regards to the servicing platform for the
period as follows:

Platform: 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").

Applicable Servicing Criteria: All servicing criteria set forth in Item 1122(d),
to the extent required in the related transaction agreements or required by the
Item 1122(d) servicing criteria in regards to the activities performed by the
Company, except for the following criteria: 1122(d)(1)(iii), 1122(d)(4)(ii),
1122(d)(4)(iv), 1122(d)(4)(v), 1122(d)(4)(viii), 1122(d)(4)(ix), 1122(d)(4)(x),
1122(d)(4)(xi), 1122(d)(4)(xii) and 1122(d)(4)(xiii), which management has
determined are not applicable to the activities the Company performs with
respect to the Platform (the "Applicable Servicing Criteria").

Period: Twelve months ended December 31, 2006 (the "Period").

Third parties classified as vendors: With respect to servicing criteria
1122(d)(4)(i), the Company has engaged various vendors to handle certain Uniform
Commercial Code filing functions required by the servicing criteria ("vendors").
The Company has determined that none of the vendors is a "servicer" as defined
in Item 1101(j) of Regulation AB, and the Company elects to take responsibility
for assessing compliance with the portion of 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"). The Company has policies and procedures in place to
provide reasonable assurance that each vendor's activities comply in all

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders
of Bank of America Corporation:

We have examined management's assertion, included in the accompanying Report on
Assessment of Compliance with Servicing Criteria, that Bank of America, National
Association (the "Company") complied with the servicing criteria set forth in
Item 1122(d) of the Securities and Exchange Commission's Regulation AB for the
asset-backed securities for which the Company acted as servicer involving
residential mortgage loans, other than government sponsored entities, housing
agencies, foreign transactions or transactions that do not have scheduled
interest and/or scheduled principal remittance schedules as outlined in their
respective transaction agreements (the "Platform"), as of December 31, 2006 and
for the year then ended, excluding the criteria which the Company has determined
are not applicable to the servicing activities performed by them with respect to
the Platform, as indicated in Appendix A of the Report on Assessment of
Compliance with Servicing Criteria. As described in Appendix A, for servicing
criteria 1122(d)(2)(ii), 1122(d)(4)(iv), 1122(d)(4)(xi), 1122(d)(4)(xii) and
1122(d)(4)(xiii), 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 "servicers" 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 reasonable 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 determination of its eligibility to use
Interpretation 17.06. 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 Platform is fairly stated, in all material respects.

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 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
1122(d)(1)(iii), 1122(d)(4)(ii), 1122(d)(4)(iv), 1122(d)(4)(v),
1122(d)(4)(viii), 1122(d)(4)(ix), 1122(d)(4)(x), 1122(d)(4)(xi),
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.
