           underlying servicers have reported to the master servicer actual due
           dates as the initial due date of the transaction rather than the
           contractual due date of the loan.

           Certain losses on loans were not applied by the Securities
           Administrator in the manner required under the operative documents
           governing this transaction. Adjustments will be made by the
           Securities Administrator in subsequent months in order to rectify
           this. Please refer to Exhibit 99.5 for a detailed listing of the
           adjustments to be made.

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 (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, 2005
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, 2005 is fairly stated, in all material respects.

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.

In connection with your compliance attestation engagement relating to our
assertion about Aurora Loan Services LLC's (the "Company") compliance with the
servicing standards (the "specified minimum servicing standards") set forth in
Exhibit A to the Report of Management (as attached) and based on the Mortgage
Bankers Association of America's Uniform Single Attestation Program for Mortgage
Bankers ("USAP") during the year ended November 30, 2005, we recognize that
obtaining representations from us concerning the information contained in this
letter is a significant procedure in enabling you to form an opinion on whether
our assertion about the Company's compliance with the specified minimum
servicing standards is fairly stated in all material respects. Accordingly, we
make the following representations with respect to our compliance with the
specified minimum servicing standards during the year ended November 30, 2005,
which are true to the best of our knowledge and belief.

We recognize that, as members of management of the Company, we are responsible
for determining (identifying) the specified minimum servicing standards and
ensuring their sufficiency and adequacy based on our servicing requirements
specified in the underlying servicing agreements. We concluded and confirmed the
specified minimum servicing standards are sufficient and adequate to satisfy the
applicable requirements under our servicing agreements.

We acknowledge that, as members of management of the Company, we are responsible
for complying with the specified minimum servicing standards. We are also
responsible for establishing and maintaining effective internal control over
compliance with these standards. We have performed an evaluation of the
Company's compliance with the specified minimum servicing standards referred to
above as of November 30, 2005 and for the year then ended. Based on this
evaluation, the Company has complied with the specified minimum servicing
standards as set forth in the USAP during the year ended November 30, 2005.

We accept responsibility for our assertion (management's report) regarding the
Company's compliance with the specified minimimum servicing standards. We did
not


10350 Park Meadows Drive, Littleton, CO. 80124


(page)


base our assertion solely or primarily on your procedures in connection with
this examination or any other engagement.

There has been no known noncompliance with specified minimum servicing standards
for the year ended November 30, 2005 and through the date of this letter.

As of and for the same year ended November 30, 2005, the Company had in effect a
fidelity bond policy and an errors and omissions policy in the amounts of $110
million and $150 million, respectively.

We have made available to you all documentation related to compliance with the
specified minimum servicing standards.

There has been no fraud involving management or employees who have significant
roles in internal control over compliance with the specified minimum servicing
standards. There has been no fraud involving other employees that could have a
material effect on compliance with the specified minimum servicing standards.

There have been no written or oral notices or communications from regulatory
agencies, Securities and Exchange Commission, investors, securitization
trustees, sub-servicers, rating agencies, internal auditors, or other internal
or external parties concerning possible noncompliance with the specified minimum
servicing standards during the year ended November 30, 2005 and through the date
of this letter.

There were no legal contingencies or pending or threatened litigation related to
our servicing activities concerning possible noncompliance with the specified
minimum servicing standards during the year ended November 30, 2005 and through
the date of this letter. There were no events of servicer default, noncompliance
with servicer covenants under our servicing agreements, or other adverse events
with respect to our servicing duties and responsibilities during the year ended
December 31, 2005 and through the date of this letter.

Management is responsible for ensuring our periodic servicer reports, including
those filed in public filings (e.g., Form 8-K) of the securitization trusts,
satisfy the applicable requirements in our servicing agreements and regulatory
acts, and such requirements were met during the year ended November 30, 2005 and
through the date of this letter.

We also acknowledge that we are responsible for the fair presentation of
information in the annual reports on Form 10-K, if required, for the year ended
December 31, 2005 for which we are responsible as a servicer. We recognize you
have not been engaged to audit, review or perform any procedures on any
information in these annual reports on Form 10-K.

Whenever your attestation report and the accompanying management's assertion
regarding compliance with the specified minimum servicing standards are planned
to be


(page)


included in a public document (such as a document filed with the Securities and
Exchange Commission), we will provide to you each such document, prior to its
finalization and filing, for your review and obtain your authorization to
include your report in the public document.

No events or transactions have occurred since November 30, 2005 or are pending
that would have an effect on our compliance with the specified minimum servicing
standards at that date or for the year then ended.

We understand that your examination was conducted in accordance with attestation
standards established by the American Institute of Certified Public Accountants
and was, therefore, designed primarily for the purpose of expressing an opinion
on whether our assertion is fairly stated in all material respects, based on the
specified minimum servicing standards, and that your procedures were limited to
those that you considered necessary for that purpose.
