Independent
Accountants Report The Board of Directors 
      The Bank of
New York: We have examined the accompanying
 managements  assertion that The Bank of New York (the Company)  complied with the
PPLUS  Minimum  Servicing  Standards for the PreferredPLUS  Trust Series QWS-1
 transaction  as of and for the year ended  December 31, 2007.  With respect to servicing
 standard 4, 5 and 7,  managements  assertion  indicates that there were no  activities
 performed  during the year ended  December 31, 2007 with  respect to the  PreferredPLUS
Trust Series QWS-1  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 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 has complied  with the  aforementioned  Minimum
Servicing Standards as of and for the year ended December 31, 2007 is fairly stated, in
all material respects. /s/ KPMG LLP Chicago, Illinois

The Bank of New York (the  Company)  are  responsible  for  complying  with the

5 and 7, there were no  activities  performed  during the year ended  December 31, 2007
with respect to the PreferredPLUS  Trust Series QWS-1  transaction,  because there were
no occurrences  of events that would  require the Company to perform  such  activities.
 We also are  responsible  for establishing  and  maintaining  effective  internal
 control  over  compliance  with the  PPLUS  Minimum  Servicing Standards.  We have
 performed  an  evaluation  of the  Companys  compliance  with the  requirements  of the

 QWS-1 as of and for the year ended December 31, 2007.  Based on this  evaluation,  we
