INDEPENDENT REGISTERED CERTIFIED PUBLIC ACCOUNTANT'S REPORT



To the Board of Directors of
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 such other 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 days by using a
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.

OCWEN






Management has implemented a corrective action plan to revise 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.
