Report of Independent Certified Public Accountants


To the Board of Directors of
Ocwen Loan Servicing, LLC


We have examined management's assertion that Ocwen Loan Servicing, LLC ("OLS"),
as successor to Ocwen Federal Bank FSB (the "Bank"), has 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, 2005 included in the
accompanying Management Assertion on Compliance with USAP. Management is
responsible for OLS's compliance with those minimum servicing standards. 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.

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

standards.

In our opinion, management's assertion that the Company complied with the
aforementioned minimum servicing standards for the series of certificates

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.


(PAGE)


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.
