            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Merrill Lynch Depositor, Inc.

We have examined management's assertion that Merrill Lynch Depositor, Inc. (the
"Company") has complied as of and for the year ended December 31, 2005, with
its established minimum servicing standards described in the accompanying
Management's Assertion on Compliance with PPLUS Minimum Servicing Standards with
respect to PreferredPLUS Trust Series QWS-2, dated March 24, 2006. Management
is responsible for the Company's compliance with those minimum servicing
standards. Our responsibility is to express an opinion on management's assertion
about the Company's compliance based on our examination. We did not examine The
Bank of New York's compliance with those minimum servicing standards that it is
responsible for as indicated for "the Bank" in the accompanying minimum
servicing standards. The Bank of New York's compliance with those minimum
servicing standards was examined by other accountants whose report has been
furnished to us, and our opinion, insofar as it relates to The Bank of New
York's compliance, is based solely on the report of such other accountants.

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 its minimum servicing standards and performing such other
procedures as we considered necessary in the circumstances. We believe that our
examination and the report of other accountants provide a reasonable basis for
our opinion. Our examination does not provide a legal determination on the
Company's compliance with its minimum servicing standards.

In our opinion, based on our examination and the report of other accountants,
management's assertion that the Company complied with the aforementioned minimum
servicing standards as of and for the year ended December 31, 2005, is fairly
stated, in all material respects, based on the criteria set forth in Appendix I.
