                       Report on Management's Assertion on
   Compliance With the Specified Minimum Servicing Standards Set Forth in the
            Uniform Single Attestation Program for Mortgage Bankers


            Report of Independent Registered Public Accounting Firm

Member
Aurora Loan Services LLC

We have examined  management's  assertion,  included in the accompanying  report
titled  Report of  Management,  that Aurora Loan  Services  LLC (the  "Company")
complied with the  servicing  standards  identified in Exhibit A (the  specified
minimum  servicing  standards) to the Report of  Management  as set forth in the
Mortgage Bankers Association of America's Uniform Single Attestation Program for
Mortgage  Bankers (USAP) during the year ended November 30, 2005.  Management is
responsible for the Company's  compliance with those specified 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  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
specified 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 the  specified  minimum
servicing standards.

In our  opinion,  management's  assertion  that the  Company  complied  with the
aforementioned  specified  minimum  servicing  standards  during  the year ended
November 30, 2005, is fairly stated, in all material respects.

Board of Directors and Stockholder
of Colonial Savings, F.A.

We examined  management's  assertion about Colonial Savings,  F.A.  ("Colonial")
compliance  with the minimum  servicing  standards  identified  in the  Mortgage
Bankers Association of America's Uniform Single Attestation Program for Mortgage
Bankers  ("USAP") as of and for the year ended  September 30, 2005,  included in
the accompanying management's assertion about Colonial's compliance based on our
examination.

Our examination was made in accordance with attestation standards established by
the  American  Institute  of  Certified  Public  Accountants  and,  accordingly,
included examining,  on a test basis,  evidence about Colonial's compliance with
the 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  Colonial's   compliance  with  the  minimum  servicing
standards.

In  our  opinion,   management's  assertion  that  Colonial  complied  with  the
aforementioned  minimum  servicing  standards  as of  and  for  the  year  ended
September 30, 2005, is fairly stated, in all material aspects.

                              Report of Management

responsible  for  complying  with  the  servicing  standards  identified  in the

         been received by the  servicing  entity at least thirty (30) calendar
         days prior to these dates.

     4.  Any late payment  penalties paid in conjunction with the payment of any
         tax bill or insurance  premium notice shall  be paid from the servicing
         entity's  funds  and not  charged to  the mortgagor,  unless  the  late
         payment was due to the mortgagor's error or omission.

     5.  Amounts remitted to investors per the servicer's investor reports shall
         agree with cancelled checks, or  other  form  of  payment, or custodial
         bank statements.

       Annual Officer's Certificate as to Compliance

Dear Ms. Wallace:

The undersigned Officer certifies the following for the period ending on
December 31, 2005:

1.     I have  reviewed  the  activities and  performance of the Master Servicer
       during  the  preceding  calendar  year  under  the  terms  of  the  Trust
       Agreements  and  to  the  best  of  this Officer's knowledge,  the Master
       Servicer has fulfilled all of its duties, responsibilities or obligations
       under the Agreements;

2.     Based on said  review and  to the best  of this  Officer's knowledge, the
       Master Servicer  is not in default of  its obligations under the terms of
       the Trust Agreements in any material  respect, or, if there is  a default
       in the fulfillment of its  obligations, a description  of each default or
       failure  and  the nature  and status  thereof has  been reported  to this
       Officer;

3.     To the best  of this Officer's knowledge,  nothing has arose to lead this
       Officer to  believe  that its  Servicer has failed to perform  any of its
       duties,  responsibilities  and  obligations under its Servicing Agreement
       during the preceding calendar year;

4.     To the best of  this Officer's  knowledge, the Servicer is not in default
       of its obligations  under  the terms of  its Servicing  Agreement  in any
       material  respect, or, if  there is a default  in the fulfillment  of its
       obligations, a description  of each default or failure and the nature and
       status thereof has been reported to this Officer;

5.     The Master Servicer has received from its Servicer such Servicer's annual
       certificate of compliance  and a  copy of  such  Servicer's  annual audit
       report,  in  each  case  to  the  extent  required  under the  applicable
       Servicing Agreement, or,  if any such  certificate or report has not been
       received by the  Master Servicer, the  Master Servicer is  using its best
       reasonable efforts to obtain such certificate or report.
