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
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.

With respect to the Platform and the Period, the Company provides the following
assessment of compliance with respect to the Applicable Servicing Criteria:

1. The Company is responsible for assessing its compliance with the Applicable
Servicing Criteria.

2. The Company has assessed compliance with the Applicable Servicing Criteria,
including servicing criteria for which compliance is determined based on
Interpretation 17.06 as described above, as of and for the Period. In performing
this assessment, management used the criteria set forth by the Securities and
Exchange Commission in paragraph (d) of Item 1122 of Regulation AB.

3. Other than as identified on Schedule A hereto, as of and for the Period, the
Company was in material compliance with the Applicable Servicing Criteria. Any
material instances of noncompliance by a vendor of which the Company is aware
and any material deficiency in the Company's policies and procedures to monitor
vendors' compliance that the Company has identified is specified on Schedule A
hereto.

KPMG LLP, a registered public accounting firm, has issued an attestation
report with respect to the Company's foregoing assessment of compliance as of
and for the Period.

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

of KPMG International, a Swiss cooperative.

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.
