Independent
Accountants’ Report The Board of Directors 
      The Bank of
New York Mellon: We have examined the accompanying
management’s assertion that The Bank of New York Mellon (formerly The Bank of New York),  (the “Company”) complied with the PPLUS
Minimum Servicing Standards for the PreferredPLUS Trust Series QWS-2 transaction as of
and for the year ended December 31, 2011. With respect to servicing standard 4, 5, 6 and 7,
management’s assertion indicates that there were no activities performed during the year
ended December 31, 2011 with respect to the PreferredPLUS  Trust Series QWS-2
transaction, because there were no occurrences of events that would require the Company
to perform such activities. 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 made in
accordance with standards established by the American Institute of Certified Public
Accountants and, accordingly, included examining, on a test basis, evidence about the
Company’s compliance with the PPLUS Minimum Servicing Standards specified above 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 the Company’s compliance with the PPLUS Minimum
Servicing Standards. In our opinion, management’s
assertion that The Bank of New York Mellon  has complied with the aforementioned PPLUS Minimum
Servicing Standards as of and for the year ended December 31, 2011 is fairly stated, in
all material respects. /s/ KPMG Chicago, Illinois
