             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Clayton Fixed Income Services
Denver, Colorado

We have examined management's assertion, included in the accompanying
Certification Regarding Compliance with Applicable Serving Criteria Report
("Management's Report"), that Clayton Fixed Income Services ("CFIS") complied
with the following list of specified requirements pursuant to agreements with
certain Trusts identified below. The transactions covered by this report include
mortgage-backed securities transactions (each, a "Trust") for which CFIS acted
as credit risk manager (the "Platform"), including: FFMLT 2006-FF16, Soundview
2006-WF1 and Soundview 2006-WF2.

Clayton shall have prepared and made available on or about the 15th calendar day
of each month the following reports (the "Reports"):

          (i)   The Watchlist Report including a listing of mortgage loans in
                any delinquency status, including current and paid off loans,
                and any additional comments by Clayton.

          (ii)  The Loss Severity Report providing a compilation and summary of
                all losses, indicating the loan loss severity for each mortgage
                pool.

          (iii) The Mortgage Insurance Claims Report providing a summary of
                claims submitted to the PMI Insurer by the servicers, claim
                payment and denial information, and penalties accessed.

          (iv)  The Prepayment Premiums Report indicating prepayment premiums
                accessed or waived by each servicer.

          (v)   The Analytics Report including statistical and/or graphical
                portrayals of:

                (A)  The delinquency trend

                (B)  Prepayment analysis, and

                (C)  The standard default assumptions

We have not examined any of the underlying information contained within the
Reports, and as such, express no opinion related to the underlying information
contained within the Reports.

Management is responsible for Clayton Fixed Income Services' compliance with
those requirements. Our responsibility is to express an opinion on management's
assertion about Clayton Fixed Income Services' compliance based on our
examination.

Our examination was conducted in accordance with the attestation standards of
the Public Company Accounting Oversight Board (United States) and, accordingly,
included examining, on a test basis, evidence about Clayton Fixed Income
Services' compliance with those requirements and performing such other
procedures as we considered necessary in the circumstances. We believe that our
examination provides a reasonable basis for our opinion. Our examination does
not provide a legal determination on Clayton Fixed Income Services' compliance
with specified requirements.

In our opinion, except for items observed in the Management Report, management's
assertion that Clayton Fixed Income Services complied with the aforementioned
requirements during the period from January 1, 2006 to December 31, 2006 is
fairly stated, in all material respects.

We have not examined any of the other assertions included in management's report
and, accordingly, express no opinion on assertions not specifically identified
above.
