                       Report of Independent Auditors


To the Board of Directors of
Chase Manhattan Mortgage Corporation:


We  have  examined   management's   assertion  about  Chase  Manhattan  Mortgage
Corporation's (the "Company") compliance with the minimum servicing standards as
set forth 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, 2004. The Company has  interpreted  USAP and  determined  that USAP
minimum  servicing  standards I.1, I.2, I.3, III.1,  III.5,  IV.1, and VII.1 are
applicable to master servicers and are included in the  accompanying  management
assertion  (see  Exhibit  I).   Management  is  responsible  for  the  Company's
compliance with these minimum  servicing  standards.  Our  responsibility  is to
express an opinion on  management's  assertion,  as it relates to the  Company's
compliance with the  aforementioned  minimum servicing  standards,  based on our
examination.  The Company has interpreted  USAP and determined that USAP minimum
servicing  standards I.4, II.1, II.2, II.3, II.4, III.2,  III.3,  III.4,  III.6,
V.1, V.2, V.3, V.4 and VI.1 are not applicable to master servicers.  The Company
uses a subservicing organization to perform the servicing obligations subject to
servicing  standards I.4, II.1, II.2, II.3, II.4, III.2,  III.3,  III.4,  III.6,
V.1,  V.2,  V.3,  V.4,  and VI.1 of the USAP.  We did not examine the  Company's
compliance with the servicing standards referred to in the previous sentence and
accordingly, do not express an opinion thereon.

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 such 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 solely as they relate to standards
I.1,  I.2,  I.3,  III.1,  III.5,  IV.1,  and VII.1 as of and for the year  ended
December 31, 2004 is fairly stated, in all material respects.

             Management's Assertion Concerning Compliance with USAP
                          Minimum Servicing Standards


March 23, 2005

As of and for  the  year  ended  December  31,  2004,  Chase  Home  Finance  LLC
(successor by merger to Chase Manhattan  Mortgage  Corporation)  (the "Company")
has complied in all material respects with the minimum  servicing  standards set
forth  in  the  Mortgage  Bankers   Association  of  America's   Uniform  Single
Attestation  Program for Mortgage  Bankers  ("USAP") that we have determined are
applicable to master  servicers.  We have  interpreted  USAP and determined that
minimum servicing  standards I.1, I.2, I.3, III.1, III.5, IV.1, and VII.1 as set
forth in USAP are applicable to master servicers.  We have also interpreted that
USAP minimum  servicing  standards I.4, II.1, II.2, II.3,  II.4,  III.2,  III.3,
III.4,  III.6,  V.1,  V.2,  V.3,  V.4 and  VI.1  as set  forth  in USAP  are not
applicable  to master  servicers;  for these  minimum  servicing  standards  the
Company relies on the performance of its  subservicers.  This assertion  relates
specifically to the Company's Master Servicing Portfolio.

It is  the  Company's  policy  to  obtain  and  review  USAP  reports  from  the
independent  auditors of its  subservicers on an annual basis.  Not all of those
USAP reports for the year ended  December 31, 2004 are available as of March 23,
2005. As of March 23, 2005, the Company has obtained USAP reports for 32% of its
subservicers.  These  subservicers  serviced loans  comprising 90% of the unpaid
principal balance of the Company's Master Servicing Portfolio as of December 31,
2004.  Instances of  non-compliance  noted in the USAP reports received from the
subservicers as of March 23, 2005, have been included in Exhibit II hereto.

As of and for this same period, the Company had in effect fidelity bond and
errors and omissions  policy in the amounts of  $250,000,000  and  $25,000,000,
respectively.

                      Chase Manhattan Mortgage Corporation
                      Subservicers' USAP Report Exceptions


It is the policy of Chase  Manhattan  Mortgage  Corporation  (the  "Company") to
obtain Uniform Single Attestation  Program for Mortgage Bankers ("USAP") reports
from the independent  auditors of its  subservicers as of and for the year ended
December 31, 2004.  As of March 23, 2005,  the Company has obtained and reviewed
USAP reports for 32% of its  subservicers.  These  subservicers  serviced  loans
comprising 90% of the unpaid principal balance of the Company's Master Servicing
Portfolio as of December 31, 2004. The Company noted instances of  noncompliance
included in the USAP reports received as of March 23, 2005, which are summarized
below.



Servicer                                        Exception

Cendant Mortgage  Corporation     The Company did not comply with the
                                  requirement to prepare custodial bank account
                                  reconciliations within 45 calendar days after
                                  the cutoff date and the requirement to resolve
                                  reconciling items within 90 calendar days of
                                  their original identification as specified by
                                  their minimum servicing standards.


North Fork Bancorporation, Inc.   The mortgage interest rate changes on certain
                                  Home Equity Lines of Credit were not adjusted
                                  at the appropriate date in accordance with
                                  the mortgagor's loan documents. This resulted
                                  in the mortgagor being overcharged for the
                                  period from the interest rate change until
                                  the correct effective date, which was the
                                  first day of the following month.


GMAC Mortgage Corporation         There were bank accounts over the course of
                                  several months where the Company was not in
                                  full compliance with USAP requirements as it
                                  related to the preparation of custodial bank
                                  reconciliations within 45 calendar days of
                                  cutoff as well as the resolution of
                                  reconciling items within 90 calendar days of
                                  original identification. The Company
                                  remediated the issues related to the
                                  preparation of custodial bank accounts
                                  reconciliations within 45 calendar days as of

                                MORTGAGE BANKERS

Board of Directors
Specialized Loan Servicing, LLC

We have examined management's assertion about Specialized Loan Servicing,  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, 2004
included in the accompanying management assertion. 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 conducted in accordance  with 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  Specialized  Loan Servicing,  LLC
complied with the aforementioned  minimum servicing  standards as of and for the
year ended December 31, 2004 is fairly stated, in all material respects.

and for the year ended  December 31, 2004.  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' compliance
based on our examination.

Our  examination  was  conducted  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  specified above 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 Countrywide  Financial Corporation
and  subsidiaries,  (including its  wholly-owned  subsidiary,  Countrywide  Home
Loans,  Inc. (CHL) and Countrywide  Home Loans  Servicing,  L.P., a wholly-owned
subsidiary of CHL, complied with the aforementioned  minimum servicing standards
as of and for year ended  December  31, 2004 is fairly  stated,  in all material
respects.

                        Independent Accountants' Report

The Board of Directors
North Fork Bancorporation Inc.:

We have examined management's assertion, included in the accompanying Management
Assertion,  that GreenPoint Mortgage Funding, Inc., a wholly owned subsidiary of
North Fork  Bancorporation,  Inc., complied with the minimum servicing standards
set forth 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, 2004.  Management is responsible for GreenPoint  Mortgage  Funding,
Inc.'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 conducted in accordance with attestion standards established
by the American  Institute of Certified  Public  Accountants  and,  accordingly,
included examining, on a test basis, evidence about GreenPoint Mortgage Funding,
Inc.'s  compliance  with the minimum  servicing  standards  specified  above 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
GreenPoint  Mortgage  Funding,  Inc.'s  compliance  with the  minimum  servicing
standards.

Management   identified  the  following  material   noncompliance  with  minumum
servicing standards over mortgage payments as of and for the year ended December
31,  2004.  The mortgage  interest  rate changes on certain Home Equity Lines of
Credit  were  not  adjusted  at the  appropriate  date in  accordance  with  the
mortgagor's loan documents. This resulted in the mortgagor being overcharged for
the period from the interest rate change until the correct effective date, which
was the first day of the following month.

In our  opinion,  except for the material  noncompliance  described in the third
paragraph,   management's  assertion  that  GreenPoint  Mortgage  Funding,  Inc.
complied with the aforementioned  minimum servicing  standards as of and for the
year ended December 31, 2004 is fairly stated, in all material respects.

                              Management's Asserton

March 17, 2005

As of and for the year ended  December 31, 2004,  GreenPoint  Mortgage  Funding,
Inc.  (the  "Company"),  has complied in all material  respects with the minimum
servicing  standards set forth in the Mortgage Bankers  Association of America's
Uniform  Single  Attestation  Program  for  Mortgage  Bankers,  except  for  the
following:

..    In certain  circumstances,  the mortgage  interest  rate changes on certain
     Home Equity  Lines of Credit were not adjusted at the  appropriate  date in
     accordance  with the  mortgagor's  loan  documents.  This  resulted  in the
     mortgagor  being  overcharged  for the period from the interest rate change
     until the correct  effective date, which was the first day of the following
     month.  This error was identified by Management and the systemic issue that
     caused the  incorrrect  calculation  of interest was resolved  prior to the
     issuance of this letter.

As of and for the year ended  December  31,  2004,  the  Company had in effect a
fidelity  bond in the  amount  of  $25,000,000  for a single  loss  limit and an
aggregate limit of liability of $50,000,000  and an errors and omissions  policy
in the amount of $25,000,000  for a single loss limit and not aggregate limit of
liability.

       Servicer Compliance Defaults under Pooling and Servicing Agreement

There have been no defaults by Specialized Loan Servicing, LLC ("SLS" in
the fulfillment of its obligations under the Terwin Mortgage Trust Series
2004-3HE Pooling and Servicing Agreement ("PSA") during the 2004 calendar year,
except for the following:

     (i) To the extent that any  defaults  have been  reported in the  following
reports  delivered  by SLS  pursuant  to the PSA (a copy  of  each of  which  is
attached hereto):  (A) the annual independent public accountants' Uniform Single
Attestation  Program for Mortgage Bankers report,  delivered pursuant to Section
3.18 of the PSA; and (ii) the quarterly  independent  auditor servicing reports,
delivered pursuant to Section 3.28 of the PSA; and

     (ii)  Pursuant to Section  3.05(d) of the PSA, the Servicer was required to
deposit  Prepayment  Penalties into the Servicer  Collection  Account within two
Business Days after receipt;  however,  under its previous  payment clearing and
processing  procedures,  SLS was not  sweeping  Prepayment  Penalties  into  the
Servicer  Collection  Account  on a  daily  basis,  but  rather  remitting  such
Prepayment  Penalties on a monthly  basis.  All defaults  from such delay in the
remittance  of  Prepayment  Penalties  have been  cured by SLS upon its  monthly
remittance  for the timely  distribution  of such  Prepayment  Penalties  by the
Securities  Administrator under the PSA. In addition, SLS has since modified its
payment  clearing  and  processing  procedures  to sweep such amounts on a daily
basis, so that Prepayment  Penalties are deposited into the Servicer  Collection
Account within two Business Days after receipt.
