REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To The Partners of Litton Loan Servicing LP:

     We have examined management's assertion  that Litton Loan Servicing LP (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
Assertion  Report dated  February 7, 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.

     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  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
provides a reasonable  basis for our opinion. Our examination does not provide a
legal  determination  of  the  Company's  compliance  with its minimum servicing
standards.

     In our opinion,  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.
