             Report of Independent Registered Public Accounting Firm
                Regulation AB Item 1122 Master 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 Master Servicing Platform"), as defined
in the Management Certification, as of and for the year ended December 31, 2006,
except for 1122(d)(1)(ii), 1122(d)(1)(iii), 1122(d)(2)(iii), 1122(d)(2)(vi),
1122(d)(3)(i)(C), 1122(d)(4)(i), 1122(d)(4)(ii), 1122(d)(4)(iv) through
1122(d)(4)(xiii) and 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 Master 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 Master Servicing
Platform, testing of less than all of the servicing activities related to the
Regulation AB Item 1122 Master Servicing 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.

ERNST & YOUNG

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 Regulation AB 1122 Master Servicing Platform, is
fairly stated, in all material respects.
