REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors of
NovaStar Mortgage, Inc. and subsidiaries
Kansas City, Missouri

     We have examined  management's  assertion that NovaStar  Mortgage,  Inc. (a
wholly  owned  subsidiary  of NovaStar  Financial,  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
dated March 22, 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  on 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.

complied,  in all material  respects,  with the  Company's  established  minimum
servicing standards for single-family residential mortgage loans as set forth in

Association  of  America's  Uniform  Single  Attestation  Program  for  Mortgage
