INDEPENDENT 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 interest on escrows 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,
2003. 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 interest on escrows applicable to the Bank during
the year ended December 31, 2003. 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, 2003 is fairly stated, in all material
respects.

MANAGEMENT ASSERTION ON COMPLIANCE WITH USAP

March 12, 2004

As of and for the year ended December 31,2003, except as specifically noted
below, Ocwen Federal Bank FSB (the "Bank") has complied in al1 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
recol1ciliation; 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,
2003 were not specifically identified and/or 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 Company, and the Company believes these items will
not have a material impact on the status of any custodial accounts.

Standard: Interest on escrow accounts shall be paid, or credited, to
mortgagors in accordance with the applicable state laws.

Interest on escrow accounts in certain states was not paid, or credited,
to mortgagors in accordance with the applicable state laws during the
year ended December 31, 2003. The Bank has corrected the affected
accounts by paying or crediting the appropriate interest on escrow.
The Bank is currently implementing an enhancement to its REALServicingTM
servicing system to ensure that, for loans collateralized by properties
located in states that require the payment of interest on escrow
accounts, the payment or crediting of such interest is in accordance
with applicable state laws.

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