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.

The Standards are based on the Mortgage Bankers  Association  of  America's  Uniform  Single  Attestation  Program  for Mortgage Bankers.  As of and for this same period, the Company had in effect a fidelity bond in the amount  of  $265,000,000  and an errors  and  omission  policy in the  amount of $25,000,000.
