with Minimum Servicing Standards Set Forth in the
Uniform Single Attestation Program for Mortgage Bankers

Report of Independent Accountants

Board of Directors
Aurora Loan Services Inc.

We have examined management's assertion, included in the
accompanying report titled Report of Management, the Aurora
Loan Services Inc. (the Company) complied with the minimum
servicing standards set forth in the Mortgage Bankers
Association of America's Uniform Single Attestation Program
for Mortgage Bankers (USAP) during the year ended November
30, 2002.  Management is responsible for the Company's
compliance with those requirements.  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 those
requirements 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 specified requirements.

In our opinion, management's assertion, that Aurora Loan
Services Inc. complied with the aforementioned
requirements during the year ended November 30, 2002,
is fairly stated, in all material respects.

This report is intended solely for the information and
use of the board of directors, management, and the

Association, and the Company's private investors and is not

Home Loans Servicing, L.P., a wholly-owned subsidiary of CHL) ("the Company")

SCHEDULE OF FINDINGS

December 31, 2002

Statement of Condition:
Interest on payoffs for four (4) states was not properly credited to the
mortgagor per the respective state laws due to a programming error that was not
correctly identifying when the Company should be paying, or crediting, the
mortgagor.

Criteria:
The Uniform Single Attestation Program for Mortgage Bankers, Section V, Item 4,
requires that interest on escrow accounts shall be paid, or credited, to
mortgagors in accordance with applicable laws.

Effect:
The Company was not properly paying, or crediting, the mortgagors for interest
on payoffs during the year ended 2002.

Recommendation:
The Company should identify all borrowers who are affected and refund the
interest immediately.  The Company should also remedy the programming error so
that the system will properly identify when the mortgagor should be paid, or
credited, for the interest on payoffs.

Corrective Action Plan:
The Company investigated this matter and identified the programming error.  The
programming error was corrected as of February 10, 2003.  The Company
identified all mortgagors affected and will send a refund to each customer that
would have received a refund at payoff had the error not occurred.  The Company
expects payment to the mortgagors to occur by April 30, 2003.  The Company's
Legal Department is also revalidating the interest on escrow rules for all
states.  The Company's Internal Audit Department will be performing testing in
this area to ensure proper interest credit to mortgagors where applicable.

Report on Management's Assertion on Compliance with the Minimum Servicing
Standards Set Forth in the Uniform Single Attestation Program for Mortgage
Bankers

Report of Independent Accountants

Board of Directors
IndyMac Bank, F.S.B.

We have examined management's assertion, included in the accompanying report
titled Report of Management, that, except for noncompliance with the minimum
servicing standards for the annual analysis of escrow accounts and for payment
or accretion of interest on escrow accounts in accordance with applicable state
laws, IndyMac Bank, F.S.B. and subsidiaries (the "Bank") complied with the
minimum servicing standards set forth in the Mortgage Bankers Association of
America's Uniform Single Attestation Program for Mortgage Bankers ("USAP")
during the year ended December 31, 2002.  Management is responsible for the
Bank's compliance with those requirements.  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 those
requirements 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 Bank's compliance with specified requirements.

In our opinion, management's assertion that, except for noncompliance with the
minimum servicing standards for escrow accounts that should be analyzed, in
accordance with the mortgagor's loan documents, on at least an annual basis and
for interest on escrow accounts that should be paid, or credited, to mortgagors
in accordance with applicable state laws, the Bank complied with the
aforementioned requirements during the year ended December 31, 2002, is fairly,
in all material respects.

As discussed in management's assertion, the following instances of material
noncompliance occurred at the Bank during the year ended December 31, 2002:

- Minimum servicing standards require escrow accounts be analyzed at least
annually.  As of December 31, 2002, the Bank was in compliance with the
minimum servicing standard that requires escrow accounts be analyzed at least
annually.  However, during the year ended December 31, 2002, the Bank
identified approximately 400 escrow accounts which had not been analyzed for
more than a year.  Subsequent to the identification of this exception, the Bank
performed a review of all escrow accounts and completed the required analysis.

- Minimum servicing standards require interest on escrow accounts be paid, or
credited, to mortgagors in accordance with applicable state laws.  As of
December 31, 2002, the Bank was in compliance with the minimum servicing
standard that requires interest on escrow accounts be paid, or credited, to
mortgagors in accordance with applicable state laws.  However, during the year
ended December 31, 2002, the Bank identified certain escrow accounts for which
the timing of interest payments by the Bank differed from the respective state
requirements.  Subsequent to the identification of this exception, the Bank
made modifications to the servicing system to ensure interest on escrow
accounts was paid, or credited, in accordance with applicable state laws.

This report is intended solely for the information and use of the Board of
Directors, audit committee, management, Fannie Mae, Freddie Mac, Ginnie Mae and
other investors in serviced assets and is not intended to be and should not be
used by anyone other than these specified parties.

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 interest on escrows described in the third 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, 2002.  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
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 Bank's compliance with the minimum servicing
standards.

Our examination disclosed noncompliance with minimum servicing standards in
certain states related to interest on escrows applicable to the Bank during the
year ended December 31, 2002.  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, 2002 is fairly stated, in all material
respects.

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 April
30, 2002 is fairly stated, in all material respects.

Gentlemen:

As of and for the year ended December 31, 2002, Countrywide Financial
Corporation (formerly Countrywide Credit Industries, Inc.,) and Subsidiaries
(which includes its wholly-owned subsidiary, Countrywide Home Loans, Inc.
("CHL"), and Countrywide Home Loans Servicing, L.P., a wholly-owned subsidiary
of CHL) ("the Company") has complied in all material respects with the minimum

The Company investigated the matter noted in the Schedule of Findings and

send a refund to each customer that would have received a refund at payoff had
the error not occurred.  The Company expects payment to the mortgagors to occur
by April 30, 2003.  The Company's Legal Department is also revalidating the
interest on escrow rules for all states.  The Company's Internal Audit

credit to mortgagors where applicable.

Management's Assertion on Compliance with the Minimum Servicing Standards Set
Forth in the Uniform Single Attestation Program for Mortgage Bankers

Report of Management


We, as members of management of IndyMac Bank, F.S.B. (the "Bank"), are
responsible for complying with the minimum servicing standards as set forth in
the Mortgage Bankers Association of America's Uniform Single Attestation
Program for Mortgage Bankers ("USAP").  We are also responsible for
establishing and maintaining effective internal control over compliance with
these standards.  We have performed an evaluation of the Bank's compliance with
the minimum servicing standards set forth in the USAP as of December 31, 2002
and for the year then ended.  Based on this evaluation, we assert that during
the year ended December 31, 2002, the Bank complied, in all material respects,
with the minimum servicing standards set forth in the USAP, except as described
in the following two paragraphs.

- Minimum servicing standards require escrow accounts be analyzed at least
annually.  As of December 31, 2002, the Bank was in compliance with the minimum
servicing standard that require escrow accounts be analyzed at least annually.
However, during the year ended December 31, 2002, the Bank identified
approximately 400 escrow accounts which had not been analyzed for more than a
year.  Subsequent to the identification of this exception, the Bank performed a
review of all escrow accounts and completed the required analysis.

- Minimum servicing standards require escrow accounts be paid, or credited, to
mortgagors in accordance with applicable state laws.  As of December 31, 2002,
the Bank was in compliance with the minimum servicing standard that requires
interest on escrow accounts be paid, or credited, to mortgagors in accordance
with applicable state laws.  However, during the year ended December 31, 2002,
the Bank identified certain escrow accounts for which the timing of interest
payments by the Bank differed from the respective state requirements.
Subsequent to the identification of this exception, the Bank made modifications
to the servicing system to ensure interest on escrow accounts was paid, or
credited, in accordance with applicable state laws.

As of December 31, 2002 and for the year then ended, the Bank had in effect a
fidelity bond in the amount of $35,000,000 and an errors and omissions policy
in the amount of $20,000,000.
