                         Report of Independent Auditors


To the Board of Directors and Stockholder
of Chase Home Finance LLC:



We have examined management's assertion about Chase Home Finance LLC's (formerly
known as Chase Manhattan Mortgage  Corporation) (the "Company")  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  December  31,  2004  included  in the  accompanying
management  assertion  (See  Exhibit  I).  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 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 the Company'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 the  Company's  compliance  with the 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, 2004 is fairly stated, in all material respects.

                  Mangement's Assertion Concerning Compliance

"Standards") set forth in the Mortgage Bankers Association of America's Uniform
Single Attestation Program for Mortgage Bankers ("USAP").  These Standards are
applicable only to the Company's prime and subprime mortgage portfolios.

As of and for this same  period,  the  Company had in effect  fidelity  bond and
errors and omissions  policies in the amounts of  $250,000,000  and  $25,000,000
respectively.

INDEPENDENT CERTIFIED PUBLIC ACCOUNTANT'S REPORT

To the Board of Directors
Ocwen Federal Bank FSB

We have examined management's assertion, included in the accompanying Management
Assertion on Compliance with USAP, that, except for the noncompliance related to
reconciliations  described in the third paragraph and the noncompliance  related
to adjustable  rate mortgages  described in the fifth  paragraph,  Ocwen Federal
Bank FSB (the "Bank") complied with the minimum servicing  standards  identified
in the Mortgage  Bankers  Association  of  America's  ("MBA's")  Uniform  Single
Attestation  Program for Mortgage  Bankers ("USAP") as of and for the year ended
December 31, 2004.  Management is  responsible  for the Bank's  compliance  with
those minimum servicing  standards.  Our responsibility is to express an opinion
on management's assertion about the Bank'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  Bank's  compliance  with the
minimum servicing  standards and performing other such procedures as we consider
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 Bank's compliance with the minimum servicing standards.

Our examination disclosed noncompliance with minimum servicing standards related
to account  reconciliations and adjustable rate mortgages applicable to the Bank
during the year ended December 31, 2004. Such  noncompliance is described in the
accompanying Management Assertion on Compliance with USAP.

In  our  opinion,  management's  assertion  that  the  Bank  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, 2004 is fairly  stated,  in all material
respects.

                  MANAGEMENT ASSERTION ON COMPLIANCE WITH USAP

March 11, 2005

As of and for the year ended  December 31, 2004,  except as  specifically  noted
below, Ocwen Federal Bank FSB (the "Bank") 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.

Certain  reconciling  items which arose during the year ended  December 31, 2004
were not cleared within 90 days of their original identification. Management has
developed and  implemented  an action plan and continues to resolve  outstanding
reconciling  items.  All  significant  reconciling  items have been isolated and
reviewed by the Bank, and the Bank believes these items will not have a material
impact on the status of any custodial accounts.

Standard:  Adjustments  on ARM  loans  shall be  computed  based on the  related
mortgage note and any ARM rider.


Certain ARM loans serviced by the Bank have odd due dates (i.e., due dates other
than the first day of the month).  The mortgage  notes or ARM riders for some of
the odd due date loans establish a look-back date for the applicable  index at a
certain number of days prior to each Change Date, for example,  45 days prior to
the effective  Change Date.  The Bank  determines  the  look-back  date by using
30-day month when  subtracting the actual number of look-back days stated in the
Mortgage Note or ARM rider from the effective Change Date. Some months that have
more or less than 30 days may therefore  have a  miscalculated  look-back  date,
resulting in the index rate being used on an incorrect  date,  but  generally no
more  than a  two-business  day  difference.  This has  resulted  in some  minor
differences  in the calculated  monthly  payment  amount,  which could be either
higher or lower, depending on the movement in interest rates.

Management  has  implemented  a  corrective  action plan to review the  internal
procedures  for  processing  these  types  of ARM  adjustments,  which  includes
adjusting the borrower  accounts where  necessary.  The Bank believes that these
differences did not have a material impact on any mortgagor or investor.

As of and for this same  period,  the Bank had in effect a fidelity  bond in the
amount  of  $15,000,000  and an errors  and  omissions  policy in the  amount of
$5,000,000.
