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.

Our responsibility  is to express an opinion on  management's  assertion about OLS'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 OLS'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 OLS's compliance with the minimum servicing standards.  Our examination disclosed noncompliance with minimum servicing standards related to  custodial  account   reconciliations  and  adjustments  on  adjustable  rate mortgages  applicable  to OLS during the year ended  December  31, 2005 which is described in the accompanying Management Assertion on Compliance with USAP.  In our opinion, management's assertion that OLS complied with the aforementioned minimum  servicing  standards,  except for  noncompliance  as  described  in the accompanying  Management  Assertion on  Compliance  with USAP, as of and for the year ended December 31, 2005 is fairly stated, in all material respects.   /s/ PricewaterhouseCoopers LLP - ------------------------------ PricewaterhouseCoopers LLP  February 27, 2006                                        OCWEN                   MANAGEMENT ASSERTION ON COMPLIANCE WITH USAP   February 27, 2006   As of and for the year  ended  December  31,  2005,  Ocwen Loan  Servicing,  LLC ("OLS"),  as  successor  to  Ocwen  Federal  Bank FSB (the  "Bank"),  except  as specifically noted below, has complied in all material respects with the minimum servicing  standards set forth in the Mortgage Bankers  Association of America's ("MBA's") Uniform Single Attestation Program for Mortgage Bankers ("USAP").     .      Standard: Reconciliations shall be prepared on a monthly basis for all           custodial bank  accounts and  related  bank  clearing  accounts. These           reconciliations shall be mathematically accurate, be  prepared  within           forty five  (45) calendar  days of  the cutoff date;  be reviewed  and           approved   by   someone  other   than  the  person  who  prepared  the           reconciliation; and document explanations for reconciling items. These           reconciling items  shall be resolved  within ninety (90) calendar days           of their original identification.  We have complied with all aspects of this standard with the exception of certain reconciling  items which arose during the year ended  December 31, 2005 were not cleared within 90 days of their original  identification.  All items  identified were  subsequently  cleared within 6 months.  As of December 31, 2005, there was exactly 1 reconciling  item totaling $431.07 that had not cleared within 90 days of identification.     .      Standard:  Adjustments  on ARM  loans  shall be  computed based on the           related mortgage note and any ARM rider.  Certain ARM loans  serviced by OLS were  transferred  in with an incorrect  look back date due to errors in prior servicer  records.  These certain loans had ARM adjustments  shortly after  servicing  transfer,  but prior to OLS receiving the related  mortgage  documents  from the prior  servicer.  When OLS  received  the mortgage  documents  and these  errors were  identified,  OLS did not adjust the principal and interest payment amount.  OLS has subsequently made adjustments to their  procedures  when they identify an error in prior servicer data to analyze the affect on the customer's account and make the appropriate adjustment.  As of and for this same period,  OLS had in effect a fidelity bond in the amount of $20,000,000 and an errors and omissions policy in the amount of $5,000,000.    By: /s/ Ronald M.

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.  6.

VII. Insurance Policies  1.   A fidelity bond and errors and  omissions  policy shall be in effect on the      servicing entity  throughout the reporting period in the amount of coverage      represented to investors in management's assertion.
