             Report of Independent Registered Public Accounting Firm
                Regulation AB Item 1122 Servicing Platform

Board of Directors
Aurora Loan Services LLC

We have examined management's assertion, included in the accompanying
Certification Regarding Compliance with Applicable Servicing Criteria (the
"Management Certification"), that Aurora Loan Services LLC (the "Company"),
a wholly-owned subsidiary of Lehman Brothers Bank FSB, complied with the
servicing criteria set forth in Item 1122(d) of the Securities and Exchange
Commission's Regulation AB for the residential mortgage loan master servicing
compliance platform (the "Regulation AB Item 1122 Servicing Platform"),
as defined in the Management Certification, as of and for the year ended
December 31, 2006, except for 1122(d)(1)(iii), 1122(d)(3)(i)(C), 1122(d)(4)(xv),
which the Company has determined are not applicable to the activities performed
by them with respect to the Regulation AB Item 1122 Servicing Platform covered
by this report. Management is responsible for the Company's compliance with the
applicable servicing criteria. Our responsibility is to express an opinion on
management's assertion about the Company's compliance with the applicable
servicing criteria based on our examination.

Our examination was conducted in accordance with attestation standards
established by the American Institute of Certified Public Accountants, as
adopted by 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 less than all of the individual asset backed transactions
and securities that comprise the Regulation AB Item 1122 Servicing Platform,
testing of less than all of the servicing activities related to the Regulation
AB Item 1122 Servicing Platform, and determining whether the Company processed
those selected transactions and performed those selected
activities in compliance with the servicing criteria and as permitted by the
Interpretation 17.06 of the Securities and Exchange Commission Division of
Corporation Finance Manual of Publicly Available Telephone Interpretations
("Interpretation 17.06"). 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 management's assertion, for servicing criteria 1122(d)(2)(i),
1122(d)(4)(iv), 1122(d)(4)(vii), 1122(d)(4)(xi), and 1122(d)(4)(xii), the
Company has engaged various vendors to perform certain activities required
by these servicing criteria. The Company has determined that these vendors are
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
applicable servicing criteria applicable to each vendor as permitted by
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 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.

In our opinion, management's assertion that the Company complied with the
aforementioned applicable servicing criteria, including servicing criteria
1122(d)(2)(i), 1122(d)(4)(iv), 1122(d)(4)(vii), 1122(d)(4)(xi) and
1122(d)(4)(xii) for which compliance is determined based on
Interpretation 17.06 as described above, as of and for the year ended
December 31, 2006 for the Regulation AB 1122 Servicing Platform, is
fairly stated, in all material respects.
