               POOLING AND SERVICING AGREEMENT, dated as of December 1, 2004, by
and among CWABS, INC., a Delaware corporation, as depositor (the "Depositor"),
COUNTRYWIDE HOME LOANS, INC., a New York corporation, as a seller ("CHL" or a
"Seller"), PARK MONACO INC., a Delaware corporation, as a seller ("Park Monaco"
or a "Seller", and together with CHL, the "Sellers"), COUNTRYWIDE HOME LOANS
SERVICING LP, a Texas limited partnership, as master servicer (the "Master
Servicer"), THE BANK OF NEW YORK, a New York banking corporation, as trustee
(the "Trustee"), and THE BANK OF NEW YORK TRUST COMPANY, N.A., a national
banking association, as co-trustee (the "Co-Trustee").

                              PRELIMINARY STATEMENT

        The Depositor is the owner of the Trust Fund that is hereby conveyed to
the Trustee in return for the Certificates. For federal income tax purposes, the
Trust Fund (excluding the Corridor Contract, the Carryover Reserve Fund and the
assets held in the Pre-Funding Account), will consist of three real estate
mortgage investment conduits (each a "REMIC" or, in the alternative, "REMIC 1,"
"REMIC 2" and the "Master REMIC," respectively). Each Certificate, other than
the Class A-R Certificate, will represent ownership of one or more regular
interests in the Master REMIC for purposes of the REMIC Provisions. The Class
A-R Certificate represents ownership of the sole class of residual interest in
each of REMIC 1, REMIC 2 and the Master REMIC. The Master REMIC will hold as
assets the several classes of uncertificated REMIC 2 Interests (other than the
R-2 Interest). REMIC 2 will hold as assets the several classes of uncertificated
REMIC 1 Interests (other than the R-1 Interest). REMIC 1 will hold as assets all
the property of the Trust Fund (excluding the Corridor Contract, the Carryover
Reserve Fund and the assets held in the Pre-Funding Account). For federal income
tax purposes, each REMIC 2 and REMIC 1 Interest (other than the R-1 Interest and
the R-2 Interest) is hereby designated as a regular interest in its respective
REMIC. The latest possible maturity date of all REMIC regular interests created
in this Agreement shall be the Latest Possible Maturity Date.

        REMIC 1:

               The REMIC 1 Interests will have the principal balances and
pass-through rates as set forth below.

Period) through the Distribution Date in February 2005, the Principal
Distribution Amount with respect to the Initial Mortgage Loans shall be

(1)     Except for the Class C Interest, this REMIC 2 Interest has a principal
        balance that is initially equal to 50% of its Corresponding Certificate
        Class issued by the Master REMIC. Principal payments, both scheduled and
        prepaid, Realized Losses, Subsequent Recoveries and interest accruing on
        the Class C Interest will be allocated to this class to maintain its
        size relative to its Corresponding Certificate Class (that is, 50%) with
        any excess payments of principal, Realized Losses and Subsequent
        Recoveries being allocated to the Class C Interest in such manner as to
        cause the principal balance of the Class C Interest to have a principal
        balance equal to (a) 50% of the principal balance of the Mortgage Loans
        plus (b) 50% of the Overcollateralized Amount for such Distribution
        Date.

(2)     On each Distribution Date, the Net Rate Cap.

(3)     The Class $100 Interest and the Class P Interest do not pay any
        interest. All Prepayment Charges will be allocated to the Class P
        Interest.

(4)     On each Distribution Date, the REMIC 2 Class X Interest is entitled to
        all interest payable on the REMIC 1 X Interest.

(5)     The Class R-2 Interest is the sole class of residual interest in REMIC
        2. It has no principal balance and pays no principal or interest.

        On each Distribution Date, the Interest Remittance Amount and the
Principal Remittance Amount payable on the REMIC 1 Regular Interests shall be
distributed with respect to the REMIC 2 Interests in the following manner:

        (1)    Interest. Interest is to be distributed with respect to each
        REMIC 2 Interest at the rate, or according to the formulas, described
        above.

        (2)    Principal. Principal shall be allocated among the REMIC 2
        Interests in the same manner that such items are allocated among their
        corresponding Certificate Classes.

(1)     The Certificates will accrue interest at the related Pass-Through Rates
        identified in this Agreement. Any entitlement of any Class of
        Certificates to Net Rate Carryover will be treated as paid by the Master
        REMIC to the Class C Certificates and then paid to such Class of
        Certificates pursuant to a limited recourse cap contract as described in
        Section 8.11 herein.

(2)     The Class C Certificates have no Certificate Principal Balance.

(3)     For each Interest Accrual Period the Class C Certificates are entitled
        to an amount (the "Class C Distributable Amount") equal to the sum of
        (a) the interest payable on the REMIC 2 X Interest and (b) a specified
        portion of the interest on the REMIC 1 "I" and

                                       4
<PAGE>

        "S" Interests equal to the excess of the Net Rate Cap over the product
        of two and the weighted average interest rate of the REMIC 2 Regular
        Interests (other than the P, R-2 and X Interests) with each such Class
        other than the C Interest, subject to a cap equal to the Pass-Through
        Rate of the Corresponding Master REMIC Class and the C Interest subject
        to a cap of 0.00%. The Pass-Through Rate of the Class C Certificates
        shall be a rate sufficient to entitle it to all interest accrued on the
        REMIC 1 "I" and "S" Interests less the interest accrued on the other
        Certificates issued by the Master REMIC. The Class C Distributable
        Amount for any Distribution Date is payable from current interest on the
        Mortgage Loans.

(4)     For each Distribution Date the Class P Certificates are entitled to all
        Prepayment Charges distributed with respect to the REMIC 2 Class P
        Interests.

(5)     The Class A-R Certificates represent the sole class of residual interest
        in each REMIC created hereunder. The Class A-R Certificates are not
        entitled to distributions of interest.

The foregoing REMIC structure is intended to cause all of the cash from the
Mortgage Loans to flow through to the Master REMIC as cash flow on a REMIC
regular interest, without creating any shortfall--actual or potential (other
than for credit losses)--to any REMIC regular interest. It is not intended that
the Class A-R be entitled to any cash flows pursuant to this agreement except as
provided in Section 3.08 hereunder.

Property; provided, however, that the net monthly rental income (if any) from
such REO Property deposited in the Certificate Account for such Distribution

Mortgage Loan related to such REO Property; provided, further, that for the
avoidance of doubt no Advances shall be required to be made in respect of any

deposit in the Pre-Funding Account, if any.

               Appraised Value: The appraised value of the Mortgaged Property
based upon the appraisal made for the originator of the related Mortgage Loan by
an independent fee appraiser at the time of the origination of the related
Mortgage Loan, or the sales price of the Mortgaged Property at the time of such
origination, whichever is less, or with respect to any Mortgage Loan originated
in connection with a refinancing, the appraised value of the Mortgaged Property
based upon the appraisal made at the time of such refinancing.

               originator to the applicable Seller, or, if the original
               Mortgage Note has been lost or destroyed and not replaced, an
               original lost note affidavit from the applicable Seller, stating
               that the original Mortgage Note was lost or destroyed, together
               with a copy of the related Mortgage Note;

                      (ii) in the case of each Mortgage Loan that is not a MERS
               Mortgage Loan, the original recorded Mortgage, and in the case of
               each MERS Mortgage Loan, the original Mortgage, noting the
               presence of the MIN of the Mortgage Loan and language indicating
               that the Mortgage Loan is a MOM Loan if the Mortgage Loan is a
               MOM Loan, with evidence of recording indicated thereon, or a copy
               of the Mortgage certified by the public recording office in which
               such Mortgage has been recorded;

                      (iii) in the case of each Mortgage Loan that is not a MERS
               Mortgage Loan, a duly executed assignment of the Mortgage to
               "Asset-Backed Certificates, Series 2004-AB2, CWABS, Inc., by The

               under the Pooling and Servicing Agreement dated as of December 1,
               2004, without recourse" (each such assignment, when duly and
               validly completed, to be in recordable form and sufficient to
               effect the assignment of and transfer to the assignee thereof,
               under the Mortgage to which such assignment relates);

                      (iv) the original recorded assignment or assignments of
               the Mortgage together with all interim recorded assignments of
               such Mortgage (noting the presence of a MIN in the case of each
               MERS Mortgage Loan);

                      (v) the original or copies of each assumption,
               modification, written assurance or substitution agreement, if
               any; and

                      (vi) the original or duplicate original lender's title
               policy or a printout of the electronic equivalent and all riders
               thereto or, in the event such original title policy has not been
               received from the insurer, such original or duplicate original
               lender's title policy and all riders thereto shall be delivered
               within one year of the Closing Date.

               In addition, in connection with the assignment of any MERS
Mortgage Loan, each Seller agrees that it will cause, at such Seller's own
expense, the MERS(R) System to indicate (and provide evidence to the Trustee
that it has done so) that such Mortgage Loans have been assigned by such Seller
to the Trustee in accordance with this Agreement for the benefit of the
Certificateholders by including (or deleting, in the case of Mortgage Loans
which are repurchased in accordance with this Agreement) in such computer files
(a) the code "[IDENTIFY TRUSTEE SPECIFIC CODE]" in the field "[IDENTIFY THE
FIELD NAME FOR TRUSTEE]" which identifies the Trustee and (b) the code
"[IDENTIFY SERIES SPECIFIC CODE NUMBER]" in the field "Pool Field" which
identifies the series of the Certificates issued in connection with such
Mortgage Loans. The Sellers further agree that they will not, and will not
permit the Master Servicer to, and the Master Servicer agrees that it will

                                      45
<PAGE>

not, alter the codes referenced in this paragraph with respect to any Mortgage
Loan during the term of this Agreement unless and until such Mortgage Loan is
repurchased in accordance with the terms of this Agreement.

               In the event that in connection with any Mortgage Loan that is
not a MERS Mortgage Loan a Seller cannot deliver the original recorded Mortgage
or all interim recorded assignments of the Mortgage satisfying the requirements
of clause (ii), (iii) or (iv) concurrently with the execution and delivery
hereof, such Seller shall deliver or cause to be delivered to the Co-Trustee a
true copy of such Mortgage and of each such undelivered interim assignment of
the Mortgage each certified by such Seller, the applicable title company, escrow
agent or attorney, or the originator of such Mortgage, as the case may be, to be
a true and complete copy of the original Mortgage or assignment of Mortgage
submitted for recording. For any such Mortgage Loan that is not a MERS Mortgage
Loan each Seller shall promptly deliver or cause to be delivered to the
Co-Trustee such original Mortgage and such assignment or assignments with
evidence of recording indicated thereon upon receipt thereof from the public
recording official, or a copy thereof, certified, if appropriate, by the
relevant recording office, but in no event shall any such delivery be made later
than 270 days following the Closing Date; provided that in the event that by
such date such Seller is unable to deliver or cause to be delivered each such
Mortgage and each interim assignment by reason of the fact that any such
documents have not been returned by the appropriate recording office, or, in the
case of each interim assignment, because the related Mortgage has not been
returned by the appropriate recording office, such Seller shall deliver or cause
to be delivered such documents to the Co-Trustee as promptly as possible upon
receipt thereof. If the public recording office in which a Mortgage or interim
assignment thereof is recorded retains the original of such Mortgage or
assignment, a copy of the original Mortgage or assignment so retained, with
evidence of recording thereon, certified to be true and complete by such
recording office, shall satisfy a Seller's obligations in Section 2.01. If any
document submitted for recording pursuant to this Agreement is (x) lost prior to
recording or rejected by the applicable recording office, the applicable Seller
shall immediately prepare or cause to be prepared a substitute and submit it for
recording, and shall deliver copies and originals thereof in accordance with the
foregoing or (y) lost after recording, the applicable Seller shall deliver to
the Co-Trustee a copy of such document certified by the applicable public
recording office to be a true and complete copy of the original recorded
document. Each Seller shall promptly forward or cause to be forwarded to the
Co-Trustee (x) from time to time additional original documents evidencing an
assumption or modification of a Mortgage Loan and (y) any other documents
required to be delivered by the Depositor or the Master Servicer to the
Co-Trustee within the time periods specified in this Section 2.01.

               With respect to each Mortgage Loan other than a MERS Mortgage
Loan as to which the related Mortgaged Property and Mortgage File are located in
(a) the State of California or (b) any other jurisdiction under the laws of
which the recordation of the assignment specified in clause (iii) above is not
necessary to protect the Trustee's and the Certificateholders' interest in the
related Mortgage Loan, as evidenced by an Opinion of Counsel delivered by CHL to
the Trustee, and a copy to the Rating Agencies, in lieu of recording the
assignment specified in clause (iii) above, the applicable Seller may deliver an
unrecorded assignment in blank, in form otherwise suitable for recording to the
Co-Trustee; provided that if the related Mortgage has not been returned from the
applicable public recording office, such assignment, or any copy thereof, of the
Mortgage may exclude the information to be provided by the recording office. As
to any

                                      46
<PAGE>

Mortgage Loan other than a MERS Mortgage Loan, the procedures of the
preceding sentence shall be applicable only so long as the related Mortgage File
is maintained in the possession of the Co-Trustee in the State or jurisdiction
described in such sentence. In the event that with respect to Mortgage Loans
other than MERS Mortgage Loans (i) either Seller, the Depositor or the Master
Servicer or the NIM Insurer gives written notice to the Trustee that recording
is required to protect the right, title and interest of the Trustee on behalf of
the Certificateholders in and to any Mortgage Loan, (ii) a court recharacterizes
the sale of the Mortgage Loans as a financing, or (iii) as a result of any
change in or amendment to the laws of the State or jurisdiction described in the
first sentence of this paragraph or any applicable political subdivision
thereof, or any change in official position regarding application or
interpretation of such laws, including a holding by a court of competent
jurisdiction, such recording is so required, the Co-Trustee shall complete the
assignment in the manner specified in clause (iii) of the second paragraph of
this Section 2.01(g) and CHL shall submit or cause to be submitted for recording
as specified above or, should CHL fail to perform such obligations, the Trustee
shall cause the Master Servicer, at the Master Servicer's expense, to cause each
such previously unrecorded assignment to be submitted for recording as specified
above. In the event a Mortgage File is released to the Master Servicer as a
result of the Master Servicer's having completed a Request for Document Release,
the Trustee shall complete the assignment of the related Mortgage in the manner
specified in clause (iii) of the second paragraph of this Section 2.01(g).

               So long as the Co-Trustee or its agent maintains an office in the
State of California, the Co-Trustee or its agent shall maintain possession of
and not remove or attempt to remove from the State of California any of the
Mortgage Files as to which the related Mortgaged Property is located in such
State. In the event that a Seller fails to record an assignment of a Mortgage
Loan as herein provided within 90 days of notice of an event set forth in clause
(i), (ii) or (iii) of the above paragraph, the Master Servicer shall prepare
and, if required hereunder, file such assignments for recordation in the
appropriate real property or other records office. Each Seller hereby appoints
the Master Servicer (and any successor servicer hereunder) as its
attorney-in-fact with full power and authority acting in its stead for the
purpose of such preparation, execution and filing.

               In the case of Mortgage Loans that become the subject of a
Principal Prepayment between the Closing Date (in the case of Initial Mortgage
Loans) or related Subsequent Transfer Date (in the case of Subsequent Mortgage
Loans) and the Cut-off Date, CHL shall deposit or cause to be deposited in the
Certificate Account the amount required to be deposited therein with respect to
such payment pursuant to Section 3.05 hereof.

               Notwithstanding anything to the contrary in this Agreement,
within thirty days after the Closing Date (in the case of Initial Mortgage
Loans) or within twenty days after the related Subsequent Transfer Date (in the
case of Subsequent Mortgage Loans), CHL (on behalf of each Seller) shall either
(i) deliver to the Co-Trustee the Mortgage File as required pursuant to this
Section 2.01 for each Delay Delivery Mortgage Loan or (ii) (A) repurchase the
Delay Delivery Mortgage Loan or (B) substitute the Delay Delivery Mortgage Loan
for a Replacement Mortgage Loan, which repurchase or substitution shall be
accomplished in the manner and subject to the conditions set forth in Section
2.03, provided that if CHL fails to deliver a Mortgage File for any Delay
Delivery Mortgage Loan within the period provided in the prior

                                      47
<PAGE>

sentence, the cure period provided for in Section 2.02 or in Section 2.03
shall not apply to the initial delivery of the Mortgage File for such Delay
Delivery Mortgage Loan, but rather CHL shall have five (5) Business Days to
cure such failure to deliver. CHL shall promptly provide each Rating Agency
with written notice of any cure, repurchase or substitution made pursuant to
the proviso of the preceding sentence. On or before the thirtieth (30th) day
(or if such thirtieth day is not a Business Day, the succeeding Business Day)
after the Closing Date (in the case of Initial Mortgage Loans) or within
twenty days after the related Subsequent Transfer Date (in the case of
Subsequent Mortgage Loans), the Trustee shall, in accordance with the
provisions of Section 2.02, send a Delay Delivery Certification substantially
in the form annexed hereto as Exhibit G-3 (with any applicable exceptions
noted thereon) for all Delay Delivery Mortgage Loans delivered within thirty
(30) days after such date. The Trustee will promptly send a copy of such Delay
Delivery Certification to each Rating Agency.

               The Trust Fund will not acquire or hold any Mortgage Loan that
would violate the representations made by CHL in Section 2.03(b)(70) or (72).

               Section 2.02  Acceptance by Trustee of the Mortgage Loans.

               (a) The Co-Trustee acknowledges receipt, subject to the
limitations contained in and any exceptions noted in the Initial Certification
in the form annexed hereto as Exhibit G-1 and in the list of exceptions attached
thereto, of the documents referred to in clauses (i) and (iii) of Section
2.01(g) above with respect to the Mortgage Loans and all other assets included
in the Trust Fund and declares that it holds and will hold such documents and
the other documents delivered to it constituting the Mortgage Files, and that it
holds or will hold such other assets included in the Trust Fund, in trust for
the exclusive use and benefit of all present and future Certificateholders.

               The Trustee agrees to execute and deliver on the Closing Date to
the Depositor, the Master Servicer and CHL (on behalf of each Seller) an Initial
Certification substantially in the form annexed hereto as Exhibit G-1 to the
effect that, as to each Initial Mortgage Loan listed in the Mortgage Loan
Schedule (other than any Initial Mortgage Loan paid in full or any Initial
Mortgage Loan specifically identified in such certification as not covered by
such certification), the documents described in Section 2.01(g)(i) and, in the
case of each Initial Mortgage Loan that is not a MERS Mortgage Loan, the
documents described in Section 2.01(g)(iii) with respect to such Initial
Mortgage Loans as are in the Co-Trustee's possession and based on its review and
examination and only as to the foregoing documents, such documents appear
regular on their face and relate to such Initial Mortgage Loan. The Trustee
agrees to execute and deliver within 30 days after the Closing Date to the
Depositor, the Master Servicer and CHL (on behalf of each Seller) an Interim
Certification substantially in the form annexed hereto as Exhibit G-2 to the
effect that, as to each Initial Mortgage Loan listed in the Mortgage Loan
Schedule (other than any Initial Mortgage Loan paid in full or any Initial
Mortgage Loan specifically identified in such certification as not covered by
such certification) all documents required to be delivered to the Co-Trustee
pursuant to the Agreement with respect to such Initial Mortgage Loans are in its
possession (except those documents described in Section 2.01(g)(vi)) and based
on its review and examination and only as to the foregoing documents, (i) such
documents appear regular on their face and relate to such Initial Mortgage Loan,
and (ii) the information set forth in items (i), (iv), (v), (vi), (viii), (ix)
and (xiv) through (xx) of the definition of the "Mortgage Loan

                                      48
<PAGE>

Schedule" accurately reflects information set forth in the Mortgage File. On
or before the thirtieth (30th) day after the Closing Date (or if such
thirtieth day is not a Business Day, the succeeding Business Day), the Trustee
shall deliver to the Depositor, the Master Servicer and CHL (on behalf of each
Seller) a Delay Delivery Certification with respect to the Initial Mortgage
Loans substantially in the form annexed hereto as Exhibit G-3, with any
applicable exceptions noted thereon. The Co-Trustee or the Trustee, as
applicable, shall be under no duty or obligation to inspect, review or examine
such documents, instruments, certificates or other papers to determine that
the same are genuine, enforceable or appropriate for the represented purpose
or that they have actually been recorded in the real estate records or that
they are other than what they purport to be on their face.

               Not later than 180 days after the Closing Date, the Trustee shall
deliver to the Depositor, the Master Servicer and CHL (on behalf of each
Seller), and to any Certificateholder that so requests, a Final Certification
with respect to the Initial Mortgage Loans substantially in the form annexed
hereto as Exhibit H, with any applicable exceptions noted thereon.

               In connection with the Trustee's completion and delivery of such
Final Certification, the Co-Trustee, at the Trustee's direction, shall review
each Mortgage File with respect to the Initial Mortgage Loans to determine that
such Mortgage File contains the following documents:

                      (i) the original Mortgage Note, endorsed by the applicable
               Seller or the originator of such Mortgage Loan, without recourse,
               in the following form: "Pay to the order of ________________
               without recourse", with all intervening endorsements that show a
               complete chain of endorsement from the originator to such Seller,
               or, if the original Mortgage Note has been lost or destroyed and
               not replaced, an original lost note affidavit from such Seller,
               stating that the original Mortgage Note was lost or destroyed,
               together with a copy of the related Mortgage Note;

                      (ii) in the case of each Initial Mortgage Loan that is not
               a MERS Mortgage Loan, the original recorded Mortgage, and in the
               case of each Initial Mortgage Loan that is a MERS Mortgage Loan,
               the original Mortgage, noting the presence of the MIN of the
               Initial Mortgage Loan and language indicating that the Mortgage
               Loan is a MOM Loan if the Initial Mortgage Loan is a MOM Loan,
               with evidence of recording indicated thereon, or a copy of the
               Mortgage certified by the public recording office in which
               Mortgage has been recorded;

                      (iii) in the case of each Initial Mortgage Loan that is
               not a MERS Mortgage Loan, a duly executed assignment of the
               Mortgage in the form permitted by Section 2.01;

                      (iv) the original recorded assignment or assignments of
               the Mortgage together with all interim recorded assignments of
               such Mortgage (noting the presence of a MIN in the case of each
               MERS Mortgage Loan);

                                      49
<PAGE>

                      (v) the original or copies of each assumption,
               modification, written assurance or substitution agreement, if
               any; and

                      (vi) the original or duplicate original lender's title
               policy or a printout of the electronic equivalent and all riders
               thereto.

               If, in the course of such review, the Co-Trustee finds any
document or documents constituting a part of such Mortgage File that do not meet
the requirements of clauses (i)-(iv) and (vi) above, the Trustee shall include
such exceptions in such Final Certification (and the Trustee shall state in such
Final Certification whether any Mortgage File does not then include the original
or duplicate original lender's title policy or a printout of the electronic
equivalent and all riders thereto). If the public recording office in which a
Mortgage or assignment thereof is recorded retains the original of such Mortgage
or assignment, a copy of the original Mortgage or assignment so retained, with
evidence of recording thereon, certified to be true and complete by such
recording office, shall be deemed to satisfy the requirements of clause (ii),
(iii) or (iv) above, as applicable. CHL shall promptly correct or cure such
defect referred to above within 90 days from the date it was so notified of such
defect and, if CHL does not correct or cure such defect within such period, CHL
shall either (A) if the time to cure such defect expires prior to the end of the
second anniversary of the Closing Date, substitute for the related Initial
Mortgage Loan a Replacement Mortgage Loan, which substitution shall be
accomplished in the manner and subject to the conditions set forth in Section
2.03, or (B) purchase such Initial Mortgage Loan from the Trust Fund within 90
days from the date CHL was notified of such defect in writing at the Purchase
Price of such Initial Mortgage Loan; provided that any such substitution
pursuant to (A) above or repurchase pursuant to (B) above shall not be effected
prior to the delivery to the Trustee of the Opinion of Counsel required by
Section 2.05 hereof and any substitution pursuant to (A) above shall not be
effected prior to the additional delivery to the Co-Trustee of a Request for
File Release. No substitution will be made in any calendar month after the
Determination Date for such month. The Purchase Price for any such Initial
Mortgage Loan shall be deposited by CHL in the Certificate Account and, upon
receipt of such deposit and Request for File Release with respect thereto, the
Co-Trustee shall release the related Mortgage File to CHL and shall execute and
deliver at CHL's request such instruments of transfer or assignment as CHL has
prepared, in each case without recourse, as shall be necessary to vest in CHL,
or a designee, the Trustee's interest in any Initial Mortgage Loan released
pursuant hereto. If pursuant to the foregoing provisions CHL repurchases an
Initial Mortgage Loan that is a MERS Mortgage Loan, the Master Servicer shall
cause MERS to execute and deliver an assignment of the Mortgage in recordable
form to transfer the Mortgage from MERS to CHL and shall cause such Mortgage to
be removed from registration on the MERS(R) System in accordance with MERS'
rules and regulations.

               The Co-Trustee shall retain possession and custody of each
Mortgage File in accordance with and subject to the terms and conditions set
forth herein. Each Seller shall promptly deliver to the Co-Trustee, upon the
execution or receipt thereof, the originals of such other documents or
instruments constituting the Mortgage File that come into the possession of such
Seller from time to time.

               It is understood and agreed that the obligation of CHL to
substitute for or to purchase any Mortgage Loan that does not meet the
requirements of Section 2.02(a) above shall

                                      50
<PAGE>

constitute the sole remedy respecting such defect available to the Trustee,
the Co-Trustee, the Depositor and any Certificateholder against either Seller.

               It is understood and agreed that the obligation of CHL to
substitute for or to purchase, pursuant to Section 2.02(a), any Mortgage Loan
whose Mortgage File contains any document or documents that does not meet the
requirements of clauses (i)-(iv) and (vi) above and which defect is not
corrected or cured by CHL within 90 days from the date it was notified of such
defect, shall constitute the sole remedy respecting such defect available to the
Trustee, the Co-Trustee, the Depositor and any Certificateholder against either
Seller.

               (b) The Trustee agrees to execute and deliver on the Subsequent
Transfer Date to the Depositor, the Master Servicer and CHL (on behalf of each
Seller) an Initial Certification substantially in the form annexed hereto as
Exhibit G-4 to the effect that, as to each Subsequent Mortgage Loan listed in
the Mortgage Loan Schedule (other than any Subsequent Mortgage Loan paid in full
or any Subsequent Mortgage Loan specifically identified in such certification as
not covered by such certification), the documents described in Section
2.01(g)(i) and, in the case of each Subsequent Mortgage Loan that is not a MERS
Mortgage Loan, the documents described in Section 2.01(g)(iii), with respect to
such Subsequent Mortgage Loan are in its possession, and based on its review and
examination and only as to the foregoing documents, such documents appear
regular on their face and relate to such Subsequent Mortgage Loan.

               The Trustee agrees to execute and deliver within 30 days after
the Subsequent Transfer Date to the Depositor, the Master Servicer and CHL (on
behalf of each Seller) an Interim Certification substantially in the form
annexed hereto as Exhibit G-2 to the effect that, as to each Subsequent Mortgage
Loan listed in the Mortgage Loan Schedule (other than any Subsequent Mortgage
Loan paid in full or any Subsequent Mortgage Loan specifically identified in
such certification as not covered by such certification), all documents required
to be delivered to it pursuant to this Agreement with respect to such Subsequent
Mortgage Loan are in its possession (except those described in Section
2.01(g)(vi)) and based on its review and examination and only as to the
foregoing documents, (i) such documents appear regular on their face and relate
to such Subsequent Mortgage Loan, and (ii) the information set forth in items
(i), (iv), (v), (vi), (viii), (ix) and (xiv) through (xx) of the definition of
the "Mortgage Loan Schedule" accurately reflects information set forth in the
Mortgage File. On or before the thirtieth (30th) day after the Subsequent
Transfer Date (or if such thirtieth day is not a Business Day, the succeeding
Business Day), the Trustee shall deliver to the Depositor, the Master Servicer
and CHL (on behalf of each Seller) a Delay Delivery Certification with respect
to the Subsequent Mortgage Loans substantially in the form annexed hereto as
Exhibit G-3, with any applicable exceptions noted thereon, together with a
Subsequent Certification substantially in the form annexed hereto as Exhibit
G-4. The Trustee shall be under no duty or obligation to inspect, review or
examine such documents, instruments, certificates or other papers to determine
that the same are genuine, enforceable or appropriate for the represented
purpose or that they have actually been recorded in the real estate records or
that they are other than what they purport to be on their face.

               Not later than 180 days after the Subsequent Transfer Date, the
Trustee shall deliver to the Depositor, the Master Servicer, CHL (on behalf of
each Seller) and to any

                                      51
<PAGE>

Certificateholder that so requests a Final Certification with respect to the
Subsequent Mortgage Loans substantially in the form annexed hereto as Exhibit
H, with any applicable exceptions noted thereon.

               In connection with the Trustee's completion and delivery of such
Final Certification, the Co-Trustee shall review each Mortgage File with respect
to the Subsequent Mortgage Loans to determine that such Mortgage File contains
the following documents:

                      (i) the original Mortgage Note, endorsed by the applicable
        Seller or the originator of such Mortgage Loan, without recourse, in the
        following form: "Pay to the order of ________________ without recourse",
        with all intervening endorsements that show a complete chain of
        endorsement from the originator to such Seller, or, if the original
        Mortgage Note has been lost or destroyed and not replaced, an original
        lost note affidavit from the Seller, stating that the original Mortgage
        Note was lost or destroyed, together with a copy of the related Mortgage
        Note;

                      (ii) in the case of each Subsequent Mortgage Loan that is
        not a MERS Mortgage Loan, the original recorded Mortgage, and in the
        case of each Subsequent Mortgage Loan that is a MERS Mortgage Loan, the
        original Mortgage, noting the presence of the MIN of the Subsequent
        Mortgage Loan and language indicating that the Subsequent Mortgage Loan
        is a MOM Loan if the Subsequent Mortgage Loan is a MOM Loan, with
        evidence of recording indicated thereon, or a copy of the Mortgage
        certified by the public recording office in which Mortgage has been
        recorded;

                      (iii) in the case of each Subsequent Mortgage Loan that is
        not a MERS Mortgage Loan, a duly executed assignment of the Mortgage in
        the form permitted by Section 2.01;

                      (iv) the original recorded assignment or assignments of
        the Mortgage together with all interim recorded assignments of such
        Mortgage (noting the presence of a MIN in the case of each MERS Mortgage
        Loan);

                      (v) the original or copies of each assumption,
        modification, written assurance or substitution agreement, if any; and

                      (vi) the original or duplicate original lender's title
        policy or a printout of the electronic equivalent and all riders
        thereto.

               If, in the course of such review, the Co-Trustee finds any
document or documents constituting a part of such Mortgage File that do not meet
the requirements of clauses (i)-(iv) and (vi) above, the Trustee shall include
such exceptions in such Final Certification (and the Trustee shall state in such
Final Certification whether any Mortgage File does not then include the original
or duplicate original lender's title policy or a printout of the electronic
equivalent and all riders thereto). If the public recording office in which a
Mortgage or assignment thereof is recorded retains the original of such Mortgage
or assignment, a copy of the original Mortgage or assignment so retained, with
evidence of recording thereon, certified to be true and complete by such
recording office, shall be deemed to satisfy the requirements of clause (ii),
(iii) or (iv) above, as applicable. CHL shall promptly correct or cure such
defect referred to above within 90

                                      52

days from the date it was so notified of such defect and, if CHL does not
correct or cure such defect within such period, CHL shall either (A) if the
time to cure such defect expires prior to the end of the second anniversary of
the Closing Date, substitute for the related Subsequent Mortgage Loan a
Replacement Mortgage Loan, which substitution shall be accomplished in the
manner and subject to the conditions set forth in Section 2.03, or (B)
purchase such Subsequent Mortgage Loan from the Trust Fund within 90 days from
the date CHL was notified of such defect in writing at the Purchase Price of
such Subsequent Mortgage Loan; provided that any such substitution pursuant to
(A) above or repurchase pursuant to (B) above shall not be effected prior to
the delivery to the Trustee of the Opinion of Counsel required by Section 2.05
hereof and any substitution pursuant to (A) above shall not be effected prior
to the additional delivery to the Trustee of a Request for File Release. No
substitution will be made in any calendar month after the Determination Date
for such month. The Purchase Price for any such Subsequent Mortgage Loan shall
be deposited by CHL in the Certificate Account and, upon receipt of such
deposit and Request for File Release with respect thereto, the Trustee shall
release the related Mortgage File to CHL and shall execute and deliver at
CHL's request such instruments of transfer or assignment as CHL has prepared,
in each case without recourse, as shall be necessary to vest in CHL, or a
designee, the Trustee's interest in any Subsequent Mortgage Loan released
pursuant hereto. If pursuant to the foregoing provisions CHL repurchases a
Subsequent Mortgage Loan that is a MERS Mortgage Loan, the Master Servicer
shall cause MERS to execute and deliver an assignment of the Mortgage in
recordable form to transfer the Mortgage from MERS to CHL and shall cause such
Mortgage to be removed from registration on the MERS(R) System in accordance
with MERS' rules and regulations.

               The Co-Trustee shall retain possession and custody of each
Mortgage File in accordance with and subject to the terms and conditions set
forth herein. Each Seller shall promptly deliver to the Co-Trustee, upon the
execution or receipt thereof, the originals of such other documents or
instruments constituting the Mortgage File that come into the possession of such
Seller from time to time.

               It is understood and agreed that the obligation of the Sellers to
substitute for or to purchase, pursuant to Section 2.02(b), any Subsequent
Mortgage Loan whose Mortgage File contains any document or documents that does
not meet the requirements of clauses (i)-(iv) and (vi) above and which defect is
not corrected or cured by such Seller within 90 days from the date it was
notified of such defect, shall constitute the sole remedy respecting such defect
available to the Trustee, the Co-Trustee, the Depositor and any
Certificateholder against the Sellers.

               Section 2.03  Representations, Warranties and Covenants of the

        delivery and performance by the Master Servicer of, or compliance by the
        Master Servicer with, this Agreement or the consummation of the

        loans for Fannie Mae and Freddie Mac and is a mortgagee approved by the
        Secretary of Housing and Urban Development pursuant to sections 203 and

                      (5) No litigation is pending or, to the best of CHL's
        knowledge, threatened, against CHL that would materially and adversely
        affect the execution, delivery or enforceability of this Agreement or
        any Subsequent Transfer Agreement or the ability of CHL to sell the CHL
        Mortgage Loans or to perform any of its other obligations under this

        in excess of 100.00%.

                                      56
<PAGE>

                      (11) Each Mortgage Loan is secured by a valid and
        enforceable first lien on the related Mortgaged Property subject only to
        (1) the lien of non-delinquent current real property taxes and
        assessments, (2) covenants, conditions and restrictions, rights of way,
        easements and other matters of public record as of the date of recording
        of such Mortgage, such exceptions appearing of record being acceptable
        to mortgage lending institutions generally or specifically reflected in
        the appraisal made in connection with the origination of the related
        Mortgage Loan and (3) other matters to which like properties are
        commonly subject that do not materially interfere with the benefits of
        the security intended to be provided by such Mortgage.

                      (12) Immediately prior to the assignment of each CHL
        Mortgage Loan to the Depositor, CHL had good title to, and was the sole
        owner of, such CHL Mortgage Loan free and clear of any pledge, lien,
        encumbrance or security interest and had full right and authority,
        subject to no interest or participation of, or agreement with, any other
        party, to sell and assign the same pursuant to this Agreement.

                      (13) There is no delinquent tax or assessment lien against
        any Mortgaged Property.

                      (14) There is no valid offset, claim, defense or
        counterclaim to any Mortgage Note or Mortgage, including the obligation
        of the Mortgagor to pay the unpaid principal of or interest on such
        Mortgage Note.

                      (15) There are no mechanics' liens or claims for work,
        labor or material affecting any Mortgaged Property that are or may be a
        lien prior to, or equal with, the lien of such Mortgage, except those
        that are insured against by the title insurance policy referred to in
        item (18) below.

                      (16) As of the Closing Date in the case of the Initial
        Mortgage Loans and as of the related Subsequent Transfer Date in the
        case of the Subsequent Mortgage Loans, to the best of CHL's knowledge,
        each Mortgaged Property is free of material damage and is in good
        repair.

                      (17) As of the Closing Date in the case of the Initial
        Mortgage Loans and as of the related Subsequent Transfer Date in the
        case of the Subsequent Mortgage Loans, neither CHL nor any prior holder
        of any Mortgage has modified the Mortgage in any material respect
        (except that a Mortgage Loan may have been modified by a written
        instrument that has been recorded or submitted for recordation, if
        necessary, to protect the interests of the Certificateholders and the
        original or a copy of which has been delivered to the Trustee);
        satisfied, cancelled or subordinated such Mortgage in whole or in part;
        released the related Mortgaged Property in whole or in part from the
        lien of such Mortgage; or executed any instrument of release,
        cancellation, modification (except as expressly permitted above) or
        satisfaction with respect thereto.

                      (18) A lender's policy of title insurance together with a
        condominium endorsement and extended coverage endorsement, if
        applicable, in an amount at least equal to the Cut-off Date Principal
        Balance of each such Mortgage Loan or a

                                      57
<PAGE>

        commitment (binder) to issue the same was effective on the date of the
        origination of each Mortgage Loan, each such policy is valid and
        remains in full force and effect, and each such policy was issued by a
        title insurer qualified to do business in the jurisdiction where the
        Mortgaged Property is located and acceptable to Fannie Mae and Freddie
        Mac and is in a form acceptable to Fannie Mae and Freddie Mac, which
        policy insures the Sellers and successor owners of indebtedness
        secured by the insured Mortgage, as to the first priority lien, of the
        Mortgage subject to the exceptions set forth in paragraph (11) above;
        to the best of CHL's knowledge, no claims have been made under such
        mortgage title insurance policy and no prior holder of the related
        Mortgage, including either Seller, has done, by act or omission,
        anything that would impair the coverage of such mortgage title
        insurance policy.

                      (19) No Initial Mortgage Loan was the subject of a
        Principal Prepayment in full between the Initial Cut-off Date and the
        Closing Date. No Subsequent Mortgage Loan was the subject of a Principal
        Prepayment in full between the Subsequent Cut-off Date and the
        Subsequent Transfer Date.

                      (20) To the best of CHL's knowledge, all of the
        improvements that were included for the purpose of determining the
        Appraised Value of the Mortgaged Property lie wholly within the
        boundaries and building restriction lines of such property, and no
        improvements on adjoining properties encroach upon the Mortgaged
        Property.

                      (21) To the best of CHL's knowledge, no improvement
        located on or being part of the Mortgaged Property is in violation of
        any applicable zoning law or regulation. To the best of CHL's knowledge,
        all inspections, licenses and certificates required to be made or issued
        with respect to all occupied portions of the Mortgaged Property and,
        with respect to the use and occupancy of the same, including but not
        limited to certificates of occupancy and fire underwriting certificates,
        have been made or obtained from the appropriate authorities, unless the
        lack thereof would not have a material adverse effect on the value of
        such Mortgaged Property, and the Mortgaged Property is lawfully occupied
        under applicable law.

                      (22) The Mortgage Note and the related Mortgage are
        genuine, and each is the legal, valid and binding obligation of the
        maker thereof, enforceable in accordance with its terms and under
        applicable law, except that (a) the enforceability thereof may be
        limited by bankruptcy, insolvency, moratorium, receivership and other
        similar laws relating to creditors' rights generally and (b) the remedy
        of specific performance and injunctive and other forms of equitable
        relief may be subject to equitable defenses and to the discretion of the
        court before which any proceeding therefor may be brought. To the best
        of CHL's knowledge, all parties to the Mortgage Note and the Mortgage
        had legal capacity to execute the Mortgage Note and the Mortgage and
        each Mortgage Note and Mortgage have been duly and properly executed by
        such parties.

                      (23) The proceeds of the Mortgage Loan have been fully
        disbursed, there is no requirement for future advances thereunder, and
        any and all requirements as to completion of any on-site or off-site
        improvements and as to disbursements of any

                                      58
<PAGE>

        escrow funds therefor have been complied with. All costs, fees and
        expenses incurred in making, or closing or recording the Mortgage Loan
        were paid.

                      (24) The related Mortgage contains customary and
        enforceable provisions that render the rights and remedies of the holder
        thereof adequate for the realization against the Mortgaged Property of
        the benefits of the security, including, (i) in the case of a Mortgage
        designated as a deed of trust, by trustee's sale, and (ii) otherwise by
        judicial foreclosure.

                      (25) With respect to each Mortgage constituting a deed of
        trust, a trustee, duly qualified under applicable law to serve as such,
        has been properly designated and currently so serves and is named in
        such Mortgage, and no fees or expenses are or will become payable by the
        Certificateholders to the trustee under the deed of trust, except in
        connection with a trustee's sale after default by the Mortgagor.

                      (26) Each Mortgage Note and each Mortgage is acceptable
        in form to Fannie Mae and Freddie Mac.

                      (27) There exist no deficiencies with respect to escrow
        deposits and payments, if such are required, for which customary
        arrangements for repayment thereof have not been made, and no escrow
        deposits or payments of other charges or payments due the Sellers have
        been capitalized under the Mortgage or the related Mortgage Note.

                      (28) The origination, underwriting, servicing and
        collection practices with respect to each Mortgage Loan have been in all
        respects legal, proper, prudent and customary in the mortgage lending
        and servicing business, as conducted by prudent lending institutions
        which service mortgage loans of the same type in the jurisdiction in
        which the Mortgaged Property is located.

                      (29) There is no pledged account or other security other
        than real estate securing the Mortgagor's obligations.

                      (30) No Mortgage Loan has a shared appreciation feature,
        or other contingent interest feature.

                      (31) Each Mortgage Loan contains a customary "due on sale"
        clause.

                      (32) No less than approximately the percentage specified
        in the Collateral Schedule of the Mortgage Loans are secured by single
        family detached dwellings. No more than approximately the percentage
        specified in the Collateral Schedule of the Mortgage Loans are secured
        by two- to four-family dwellings. No more than approximately the
        percentage specified in the Collateral Schedule of the Mortgage Loans
        are secured by low-rise condominium units. No more than approximately
        the percentage specified in the Collateral Schedule of the Mortgage
        Loans are secured by high-rise condominium units. No more than
        approximately the percentage specified in the Collateral Schedule of the
        Mortgage Loans are secured by manufactured housing. No more than
        approximately the percentage specified in the Collateral Schedule of the
        Mortgage Loans are secured by PUDs.

                      (33) Each Mortgage Loan was originated on or after the
        date specified in the Collateral Schedule.

                      (34) Each Mortgage Loan, other than a Two-Year Hybrid
        Mortgage Loan or a Three-Year Hybrid Mortgage Loan, had an initial
        Adjustment Date no later than the applicable date specified on the
        Collateral Schedule; each Mortgage Loan that is a Two-Year Hybrid
        Mortgage Loan had an initial Adjustment Date no later than the
        applicable date specified on the Collateral Schedule; and each Mortgage
        Loan that is a Three-Year Hybrid Mortgage Loan had an initial Adjustment
        Date no later than the applicable date specified on the Collateral
        Schedule.

                      (35) Approximately the percentage specified in the
        Collateral Schedule of the Mortgage Loans provide for a prepayment
        penalty.

                      (36) On the basis of representations made by the
        Mortgagors in their loan applications, no more than approximately the
        percentage specified in the Collateral Schedule of the Mortgage Loans
        are secured by investor properties, and no less than approximately the
        percentage specified in the Collateral Schedule of the Mortgage Loans
        are secured by owner-occupied Mortgaged Properties that are primary
        residences.

                      (37) At the Cut-off Date, the improvements upon each
        Mortgaged Property are covered by a valid and existing hazard insurance
        policy with a generally acceptable carrier that provides for fire and
        extended coverage and coverage for such other hazards as are customary
        in the area where the Mortgaged Property is located in an amount that is
        at least equal to the lesser of (i) the maximum insurable value of the
        improvements securing such Mortgage Loan or (ii) the greater of (a) the
        outstanding principal balance of the Mortgage Loan and (b) an amount
        such that the proceeds of such policy shall be sufficient to prevent the
        Mortgagor and/or the mortgagee from becoming a co-insurer. If the
        Mortgaged Property is a condominium unit, it is included under the
        coverage afforded by a blanket policy for the condominium unit. All such
        individual insurance policies and all flood policies referred to in item
        (38) below contain a standard mortgagee clause naming the applicable
        Seller or the original mortgagee, and its successors in interest, as
        mortgagee, and the applicable Seller has received no notice that any
        premiums due and payable thereon have not been paid; the Mortgage
        obligates the Mortgagor thereunder to maintain all such insurance,
        including flood insurance, at the Mortgagor's cost and expense, and upon
        the Mortgagor's failure to do so, authorizes the holder of the Mortgage
        to obtain and maintain such insurance at the Mortgagor's cost and
        expense and to seek reimbursement therefor from the Mortgagor.

                      (38) If the Mortgaged Property is in an area identified in
        the Federal Register by the Federal Emergency Management Agency as
        having special flood hazards, a flood insurance policy in a form meeting
        the requirements of the current guidelines of the Flood Insurance
        Administration is in effect with respect to such Mortgaged Property with
        a generally acceptable carrier in an amount representing coverage not
        less than the least of (A) the original outstanding principal balance of
        the Mortgage Loan, (B) the minimum amount required to compensate for
        damage or loss on a replacement cost basis,

                                      60
<PAGE>

        or (C) the maximum amount of insurance that is available under the
        Flood Disaster Protection Act of 1973, as amended.

                      (39) To the best of CHL's knowledge, there is no
        proceeding occurring, pending or threatened for the total or partial
        condemnation of the Mortgaged Property.

                      (40) There is no material monetary default existing under
        any Mortgage or the related Mortgage Note and, to the best of CHL's
        knowledge, there is no material event that, with the passage of time or
        with notice and the expiration of any grace or cure period, would
        constitute a default, breach, violation or event of acceleration under
        the Mortgage or the related Mortgage Note; and neither Seller has waived
        any default, breach, violation or event of acceleration.

                      (41) Each Mortgaged Property is improved by a one- to
        four-family residential dwelling, including condominium units and
        dwelling units in PUDs. To the best of CHL's knowledge, no improvement
        to a Mortgaged Property includes a cooperative or a mobile home or
        constitutes other than real property under state law.

                      (42) Each Mortgage Loan is being serviced by the Master
        Servicer.

                      (43) Any future advances made prior to the Cut-off Date
        have been consolidated with the outstanding principal amount secured by
        the Mortgage, and the secured principal amount, as consolidated, bears a
        single interest rate and single repayment term reflected on the Mortgage
        Loan Schedule. The consolidated principal amount does not exceed the
        original principal amount of the Mortgage Loan. The Mortgage Note does
        not permit or obligate the Master Servicer to make future advances to
        the Mortgagor at the option of the Mortgagor.

                      (44) All taxes, governmental assessments, insurance
        premiums, water, sewer and municipal charges, leasehold payments or
        ground rents that previously became due and owing have been paid, or an
        escrow of funds has been established in an amount sufficient to pay for
        every such item that remains unpaid and that has been assessed, but is
        not yet due and payable. Except for (A) payments in the nature of escrow
        payments, and (B) interest accruing from the date of the Mortgage Note
        or date of disbursement of the Mortgage proceeds, whichever is later, to
        the day that precedes by one month the Due Date of the first installment
        of principal and interest, including without limitation, taxes and
        insurance payments, the Master Servicer has not advanced funds, or
        induced, solicited or knowingly received any advance of funds by a party
        other than the Mortgagor, directly or indirectly, for the payment of any
        amount required by the Mortgage.

                      (45) The Mortgage Loans originated by CHL were
        underwritten in all material respects in accordance with CHL's
        underwriting guidelines for credit blemished quality mortgage loans or,
        with respect to Mortgage Loans purchased by CHL were underwritten in all
        material respects in accordance with customary and prudent underwriting
        guidelines generally used by originators of credit blemished quality
        mortgage loans.

                                      61

                      (46) Prior to the approval of the Mortgage Loan
        application, an appraisal of the related Mortgaged Property was obtained
        from a qualified appraiser, duly appointed by the originator, who had no
        interest, direct or indirect, in the Mortgaged Property or in any loan
        made on the security thereof, and whose compensation is not affected by
        the approval or disapproval of the Mortgage Loan; such appraisal is in a
        form acceptable to Fannie Mae and Freddie Mac.

                      (47) None of the Mortgage Loans is a graduated payment
        mortgage loan or a growing equity mortgage loan, and no Mortgage Loan is
        subject to a buydown or similar arrangement.

                      (48) The Mortgage Rates borne by the Mortgage Loans as of
        the Cut-off Date ranged between the approximate per annum percentages
        specified on the Collateral Schedule and the weighted average Mortgage
        Rate as of the Cut-off Date was approximately the per annum rate
        specified on the Collateral Schedule.

                      (49) [Reserved.]

                      (50) The Mortgage Loans were selected from among the
        outstanding one- to four-family mortgage loans in the applicable
        Seller's portfolio at the Closing Date as to which the representations
        and warranties made as to the Mortgage Loans set forth in this Sections
        2.03(b) and 2.03(c) can be made. No selection was made in a manner that
        would adversely affect the interests of Certificateholders.

                      (51) The Gross Margins on the Mortgage Loans range between
        the approximate percentages specified on the Collateral Schedule, and
        the weighted average Gross Margin was approximately the percentage
        specified in the Collateral Schedule.

                      (52) Each of the Mortgage Loans in the Mortgage Pool has a
        Due Date on or before the date specified in the Collateral Schedule.

                      (53) The Mortgage Loans, individually and in the
        aggregate, conform in all material respects to the descriptions thereof
        in the Prospectus Supplement.

                      (54) There is no obligation on the part of either Seller
        under the terms of the Mortgage or related Mortgage Note to make
        payments in addition to those made by the Mortgagor.

                      (55) Any leasehold estate securing a Mortgage Loan has a
        term of not less than five years in excess of the term of the related
        Mortgage Loan.

                      (56) Each Mortgage Loan represents a "qualified mortgage"
        within the meaning of Section 860(a)(3) of the Code (but without regard
        to the rule in Treasury Regulation ss. 1.860G-2(f)(2) that treats a
        defective obligation as a qualified mortgage, or any substantially
        similar successor provision) and applicable Treasury regulations
        promulgated thereunder.

                                      62
<PAGE>

                      (57) No Mortgage Loan was either a "consumer credit
        contract" or a "purchase money loan" as such terms are defined in 16
        C.F.R. ss. 433 nor is any Mortgage Loan a "mortgage" as defined in 15
        U.S.C. ss. 1602(aa).

                      (58) To the extent required under applicable law, each
        originator and subsequent mortgagee or servicer of the Mortgage Loan
        complied with all licensing requirements and was authorized to transact
        and do business in the jurisdiction in which the related Mortgaged
        Property is located at all times when it held or serviced the Mortgage
        Loan. Any and all requirements of any federal, state or local laws or
        regulations, including, without limitation, usury, truth-in-lending,
        real estate settlement procedures, consumer credit protection,
        anti-predatory lending, fair credit reporting, unfair collection
        practice, equal credit opportunity, fair housing and disclosure laws and
        regulations, applicable to the solicitation, origination, collection and
        servicing of such Mortgage Loan have been complied with in all material
        respects; and any obligations of the holder of the Mortgage Note,
        Mortgage and other loan documents have been complied with in all
        material respects; servicing of each Mortgage Loan has been in
        accordance with prudent mortgage servicing standards, any applicable
        laws, rules and regulations and in accordance with the terms of the
        Mortgage Notes, Mortgage and other loan documents, whether such
        origination and servicing was done by the applicable Seller, its
        affiliates, or any third party which originated the Mortgage Loan on
        behalf of, or sold the Mortgage Loan to, any of them, or any servicing
        agent of any of the foregoing;

                      (59) The methodology used in underwriting the extension of
        credit for the Mortgage Loan employs objective mathematical principles
        which relate the borrower's income, assets and liabilities to the
        proposed payment and such underwriting methodology does not rely on the
        extent of the borrower's equity in the collateral as the principal
        determining factor in approving such credit extension. Such underwriting
        methodology confirmed that at the time of origination
        (application/approval) the borrower had a reasonable ability to make
        timely payments on the Mortgage Loan;

                      (60) No borrower was required to purchase any credit life,
        disability, accident or health insurance product as a condition of
        obtaining the extension of credit. No borrower obtained a prepaid
        single-premium credit life, disability, accident or health insurance
        policy in connection with the origination of the Mortgage Loan;

                      (61) If the Mortgage Loan provides that the interest rate
        on the principal balance of the related Mortgage Loan may be adjusted,
        all of the terms of the related Mortgage pertaining to interest rate
        adjustments, payment adjustments and adjustments of the outstanding
        principal balance have been made in accordance with the terms of the
        related Mortgage Note and applicable law and are enforceable and such
        adjustments will not affect the priority of the Mortgage lien;

                      (62) The Mortgaged Property complies with all applicable
        laws, rules and regulations relating to environmental matters, including
        but not limited to those relating to radon, asbestos and lead paint and
        neither Seller nor, to the best of CHL's

                                      63
<PAGE>

        knowledge, the Mortgagor, has received any notice of any violation or
        potential violation of such law;

                      (63) There is no action, suit or proceeding pending, or to
        the best of CHL's knowledge, threatened or likely to be asserted with
        respect to the Mortgage Loan against or affecting either Seller before
        or by any court, administrative agency, arbitrator or governmental body;

                      (64) No action, inaction, or event has occurred and no
        state of fact exists or has existed that has resulted or will result in
        the exclusion from, denial of, or defense to coverage under any
        applicable hazard insurance policy, irrespective of the cause of such
        failure of coverage. In connection with the placement of any such
        insurance, no commission, fee, or other compensation has been or will be
        received by CHL or any designee of CHL or any corporation in which CHL
        or any officer, director, or employee had a financial interest at the
        time of placement of such insurance;

                      (65) Each Mortgage Loan has a fully assignable life of
        loan tax service contract which may be assigned without the payment of
        any fee;

                      (66) No Mortgagor has notified CHL or the Master Servicer
        on CHL's behalf, and CHL has no knowledge, of any relief requested or
        allowed to a Mortgagor under the Relief Act;

                      (67) Each Mortgage Loan was originated by a savings and
        loan association, savings bank, commercial bank, credit union, insurance
        company, or mortgage banking company which is supervised and examined by
        a federal or state authority, or by a mortgagee approved by the
        Secretary of Housing and Urban Development pursuant to Sections 2.03 and
        2.11 of the National Housing Act;

                      (68) Each Mortgage Loan was (A) originated no earlier than
        six months prior to the time the applicable Seller purchased such
        Mortgage Loan pursuant to a mortgage loan purchase agreement or other
        similar agreement and (B) underwritten or reunderwritten by the
        applicable Seller in accordance with the applicable Seller's
        underwriting guidelines in effect at the time the loan was underwritten
        or reunderwritten, as applicable;

                      (69) Each Mortgage Loan, at the time it was originated and
        as of the Closing Date or the Subsequent Transfer Date, complied in all
        material respects with applicable local, state and federal laws,
        including, but not limited to, all predatory and abusive lending laws;

                      (70) None of the Mortgage Loans is a "high cost" mortgage
        loan as defined by applicable federal, state and local predatory and
        abusive lending laws;

                      (71) Each Prepayment Charge is enforceable and was
        originated in compliance with all applicable federal, state and local
        laws;

                                      64
<PAGE>

                      (72) None of the Mortgage Loans that are secured by
        property located in the State of Illinois are in violation of the
        provisions of the Illinois Interest Act.;

                      (73) There is no Mortgage Loan in the Trust Fund that was
        originated on or after March 7, 2003, which is a "high cost home loan"
        as defined under the Georgia Fair Lending Act;

                      (74) No Mortgage Loan in the Trust Fund is a High Cost
        Loan or Covered Loan, as applicable (as such terms are defined in the
        then current Standard & Poor's LEVELS(R) Glossary which is now Version
        5.6 Revised, Appendix E) and no Mortgage Loan originated on or after
        October 1, 2002 through March 6, 2003 is governed by the Georgia Fair
        Lending Act; and

                      (75) Each Mortgage Loan is secured by a "single family
        residence" within the meaning of Section 25(e)(10) of the Internal
        Revenue Code of 1986 (as amended) (the "Code"). The fair market value of
        the manufactured home securing each Mortgage Loan was at least equal to
        80% of the adjusted issue price of the contract at either (i) the time
        the contract was originated (determined pursuant to the REMIC
        Provisions) or (ii) the time the contract is transferred to the
        purchaser. Each Mortgage Loan is a "qualified mortgage" under Section
        860G(a)(3) of the Code.

               (c)    Park Monaco hereby represents and warrants to the
Depositor and the Trustee as follows, as of the Cut-off Date:

        in accordance with its terms, except that (a) the enforceability hereof
        may be limited by bankruptcy, insolvency, moratorium, receivership and

                      (3) The execution and delivery of this Agreement and each

        Monaco's knowledge, threatened, against Park Monaco that would

        perform any of its other obligations under this Agreement or any

        thereof.

                      (5) No consent, approval, authorization or order of any
        court or governmental agency or body is required for the execution,
        delivery and performance by Park Monaco of, or compliance by Park Monaco
        with, this Agreement or any Subsequent Transfer Agreement or the
        consummation of the transactions contemplated hereby, or if any such
        consent, approval, authorization or order is required, Park Monaco has
        obtained the same.

                      (6) Park Monaco will treat the transfer of the Park Monaco
        Mortgage Loans to the Depositor as a sale of the Park Monaco Mortgage
        Loans for all tax, accounting and regulatory purposes.

                      (7) Immediately prior to the assignment of each Park
        Monaco Mortgage Loan to the Depositor, Park Monaco had good title to,
        and was the sole owner of, such the Park Monaco Mortgage Loan free and
        clear of any pledge, lien, encumbrance or security interest and had full
        right and authority, subject to no interest or participation of, or
        agreement with, any other party, to sell and assign the same pursuant to
        this Agreement.

               (d) Upon discovery by any of the parties hereto of a breach of a
representation or warranty set forth in Section 2.03(a) through (c) that
materially and adversely affects the interests of the Certificateholders in any
Mortgage Loan, the party discovering such breach shall give prompt notice
thereof to the other parties and the NIM Insurer. Each of the Master Servicer
and the Sellers (each, a "Representing Party") hereby covenants with respect to
the representations and warranties set forth in Sections 2.03(a) through (c)
that within 90 days of the earlier of the discovery by such Representing Party
or receipt of written notice by such Representing Party from any party of a
breach of any representation or warranty set forth herein made that materially
and adversely affects the interests of the Certificateholders in any Mortgage
Loan, it shall cure such breach in all material respects and, if such breach is
not so cured, shall, (i) if such 90-day period expires prior to the second
anniversary of the Closing Date, remove such Mortgage Loan (a "Deleted Mortgage
Loan") from the Trust Fund and substitute in its place a Replacement Mortgage
Loan, in the manner and subject to the conditions set forth in this Section; or
(ii) repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at
the Purchase Price in the manner set forth below; provided that (a) any such
substitution pursuant to (i) above or repurchase pursuant to (ii) above shall
not be effected prior to the delivery to the Trustee of the Opinion of Counsel
required by Section 2.05 hereof, (b) any such substitution pursuant to (i) above
shall not be effected prior to the additional delivery to the Trustee of a
Request for File Release and (c) any such substitution pursuant to (i) above
shall include a payment by the applicable Representing Party of any amount as
calculated under item (iii) of the definition of "Purchase Price". Any
Representing Party liable for a breach under this Section 2.03 shall promptly
reimburse the Master Servicer or the Trustee for any expenses reasonably
incurred by the Master Servicer or the Trustee in respect of enforcing the
remedies for such breach. To enable the Master Servicer to amend the Mortgage
Loan Schedule, any Representing Party liable for a breach under this Section
2.03 shall, unless it cures such breach in a timely fashion pursuant to this
Section 2.03, promptly notify the Master Servicer whether such Representing
Party intends either to repurchase, or to substitute for, the Mortgage Loan
affected by such breach. With respect to the representations and warranties
described in this Section that are made to the best of the Representing Party's
knowledge, if it is discovered by any of the Depositor, the Master Servicer, the
Sellers or the Trustee that the substance of such representation and warranty is
inaccurate and such inaccuracy materially and adversely affects the value of the
related Mortgage Loan, notwithstanding the Representing Party's lack of
knowledge with respect to the substance of such representation or warranty, such
inaccuracy shall be deemed a breach of the applicable representation or
warranty.

               With respect to any Replacement Mortgage Loan or Loans, the
applicable Seller delivering such Replacement Mortgage Loan shall deliver to the
Trustee for the benefit of the Certificateholders the related Mortgage Note,
Mortgage and assignment of the Mortgage, and such other documents and agreements
as are required by Section 2.01, with the Mortgage Note endorsed and the
Mortgage assigned as required by Section 2.01. No substitution will be made in
any calendar month after the Determination Date for such month. Scheduled
Payments due with respect to Replacement Mortgage Loans in the Due Period
related to the Distribution Date on which such proceeds are to be distributed
shall not be part of the Trust Fund and will be retained by the applicable
Seller delivering such Replacement Mortgage Loan on such Distribution Date. For
the month of substitution, distributions to Certificateholders will include the
Scheduled Payment due on any Deleted Mortgage Loan for the related Due Period
and thereafter the applicable Seller shall be entitled to retain all amounts
received in respect of such

                                      67
<PAGE>

Deleted Mortgage Loan. The Master Servicer shall amend the Mortgage Loan
Schedule for the benefit of the Certificateholders to reflect the removal of
such Deleted Mortgage Loan and the substitution of the Replacement Mortgage
Loan or Loans and the Master Servicer shall deliver the amended Mortgage Loan
Schedule to the Trustee. Upon such substitution, the Replacement Mortgage Loan
or Loans shall be subject to the terms of this Agreement in all respects, and
the applicable Seller delivering such Replacement Mortgage Loan shall be
deemed to have made with respect to such Replacement Mortgage Loan or Loans,
as of the date of substitution, the representations and warranties set forth
in Section 2.03(b) or (c) with respect to such Mortgage Loan. Upon any such
substitution and the deposit to the Certificate Account of the amount required
to be deposited therein in connection with such substitution as described in
the following paragraph, the Co-Trustee shall release to the Representing
Party the Mortgage File relating to such Deleted Mortgage Loan and held for
the benefit of the Certificateholders and shall execute and deliver at the
Master Servicer's direction such instruments of transfer or assignment as have
been prepared by the Master Servicer, in each case without recourse, as shall
be necessary to vest in the applicable Seller, or its respective designee,
title to the Trustee's interest in any Deleted Mortgage Loan substituted for
pursuant to this Section 2.03.

               For any month in which either Seller substitutes one or more
Replacement Mortgage Loans for one or more Deleted Mortgage Loans, the Master
Servicer will determine the amount (if any) by which the aggregate principal
balance of all such Replacement Mortgage Loans as of the date of substitution is
less than the Stated Principal Balance (after application of the principal
portion of the Scheduled Payment due in the month of substitution) of all such
Deleted Mortgage Loans. An amount equal to the aggregate of the deficiencies
described in the preceding sentence (such amount, the "Substitution Adjustment
Amount") shall be forwarded by the applicable Seller to the Master Servicer and
deposited by the Master Servicer into the Certificate Account not later than the
Determination Date for the Distribution Date relating to the Prepayment Period
during which the related Mortgage Loan became required to be purchased or
replaced hereunder.

               In the event that a Seller shall have repurchased a Mortgage
Loan, the Purchase Price therefor shall be deposited in the Certificate Account
pursuant to Section 3.05 on the Determination Date for the Distribution Date in
the month following the month during which such Seller became obligated to
repurchase or replace such Mortgage Loan and upon such deposit of the Purchase
Price, the delivery of the Opinion of Counsel required by Section 2.05, if any,
and the receipt of a Request for File Release, the Co-Trustee shall release the
related Mortgage File held for the benefit of the Certificateholders to such
Seller, and the Trustee shall execute and deliver at such Person's direction the
related instruments of transfer or assignment prepared by such Seller, in each
case without recourse, as shall be necessary to transfer title from the Trustee
for the benefit of the Certificateholders and transfer the Trustee's interest to
such Seller to any Mortgage Loan purchased pursuant to this Section 2.03. It is
understood and agreed that the obligation under this Agreement of the Sellers to
cure, repurchase or replace any Mortgage Loan as to which a breach has occurred
and is continuing shall constitute the sole remedy against the Sellers
respecting such breach available to Certificateholders, the Depositor or the
Trustee.

               (e) The representations and warranties set forth in this Section
2.03 shall survive delivery of the respective Mortgage Files to the Co-Trustee
for the benefit of the Certificateholders with respect to each Mortgage Loan.

               Section 2.04 Representations and Warranties of the Depositor.

               The Depositor hereby represents and warrants to the Master
Servicer and the Trustee as follows, as of the date hereof and as of each
Subsequent Transfer Date:

                      (1) The Depositor is duly organized and is validly
        existing as a corporation in good standing under the laws of the State
        of Delaware and has full power and authority (corporate and other)
        necessary to own or hold its properties and to conduct its business as
        now conducted by it and to enter into and perform its obligations under
        this Agreement.

                      (2) The Depositor has the full corporate power and
        authority to execute, deliver and perform, and to enter into and
        consummate the transactions contemplated by, this Agreement and each
        Subsequent Transfer Agreement and has duly authorized, by all necessary
        corporate action on its part, the execution, delivery and performance of
        this Agreement and each Subsequent Transfer Agreement; and this
        Agreement and each Subsequent Transfer Agreement, assuming the due
        authorization, execution and delivery hereof by the other parties
        hereto, constitutes a legal, valid and binding obligation of the
        Depositor, enforceable against the Depositor in accordance with its
        terms, subject, as to enforceability, to (i) bankruptcy, insolvency,
        reorganization, moratorium and other similar laws affecting creditors'
        rights generally and (ii) general principles of equity, regardless of
        whether enforcement is sought in a proceeding in equity or at law.

                      (3) The execution and delivery of this Agreement and each
        Subsequent Transfer Agreement by the Depositor, the consummation of the
        transactions contemplated by this Agreement, and the fulfillment of or
        compliance with the terms hereof are in the ordinary course of business
        of the Depositor and will not (A) result in a material breach of any
        term or provision of the charter or by-laws of the Depositor or (B)
        materially conflict with, result in a material breach, violation or
        acceleration of, or result in a material default under, the terms of any
        other material agreement or instrument to which the Depositor is a party
        or by which it may be bound or (C) constitute a material violation of
        any statute, order or regulation applicable to the Depositor of any
        court, regulatory body, administrative agency or governmental body
        having jurisdiction over the Depositor; and the Depositor is not in
        breach or violation of any material indenture or other material
        agreement or instrument, or in violation of any statute, order or
        regulation of any court, regulatory body, administrative agency or
        governmental body having jurisdiction over it which breach or violation
        may materially impair the Depositor's ability to perform or meet any of
        its obligations under this Agreement.

                      (4) No litigation is pending, or, to the best of the
        Depositor's knowledge, threatened, against the Depositor that would
        materially and adversely affect the execution, delivery or
        enforceability of this Agreement or any Subsequent Transfer

                                      69
<PAGE>

        Agreement or the ability of the Depositor to perform its obligations
        under this Agreement or any Subsequent Transfer Agreement in accordance
        with the terms hereof or thereof.

                      (5) No consent, approval, authorization or order of any
        court or governmental agency or body is required for the execution,
        delivery and performance by the Depositor of, or compliance by the
        Depositor with, this Agreement or any Subsequent Transfer Agreement or
        the consummation of the transactions contemplated hereby, or if any such
        consent, approval, authorization or order is required, the Depositor has
        obtained the same.

               The Depositor hereby represents and warrants to the Trustee with
respect to each Mortgage Loan as of the Closing Date or the related Subsequent
Transfer Date, as applicable, and following the transfer of the Mortgage Loans
to it by the Sellers, the Depositor had good title to the Initial Mortgage Loans
or related Subsequent Mortgage Loans, as applicable, and the related Mortgage
Notes were subject to no offsets, claims, defenses or counterclaims.

               It is understood and agreed that the representations and
warranties set forth in the two immediately preceding paragraphs shall survive
delivery of the Mortgage Files to the Co-Trustee. Upon discovery by the
Depositor or the Trustee, of a breach of any of the foregoing representations
and warranties set forth in the immediately preceding paragraph (referred to
herein as a "breach"), which breach materially and adversely affects the
interest of the Certificateholders, the party discovering such breach shall give
prompt written notice to the others and to each Rating Agency and the NIM
Insurer. The Depositor hereby covenants with respect to the representations and
warranties made by it in this Section 2.04 that within 90 days of the earlier of
the discovery it or receipt of written notice by it from any party of a breach
of any representation or warranty set forth herein made that materially and
adversely affects the interests of the Certificateholders in any Mortgage Loan,
it shall cure such breach in all material respects and, if such breach is not so
cured, shall repurchase or replace the affected Mortgage Loan or Loans in
accordance with the procedure set forth in Section 2.03(d).

               Section 2.05  Delivery of Opinion of Counsel in Connection with
                             Substitutions and Repurchases.

               (a) Notwithstanding any contrary provision of this Agreement,
with respect to any Mortgage Loan that is not in default or as to which default
is not imminent, no repurchase or substitution pursuant to Sections 2.02, 2.03
or 2.04 shall be made unless the Representing Party making such repurchase or
substitution delivers to the Trustee an Opinion of Counsel (which such
Representing Party will use reasonable efforts to obtain), addressed to the
Trustee to the effect that such repurchase or substitution would not (i) result
in the imposition of the tax on "prohibited transactions" of the Trust Fund or
contributions after the Closing Date, as defined in sections 860F(a)(2) and
860G(d) of the Code, respectively or (ii) cause the any REMIC formed hereunder
to fail to qualify as a REMIC at any time that any Certificates are outstanding.
Any Mortgage Loan as to which repurchase or substitution was delayed pursuant to
this paragraph shall be repurchased or the substitution therefor shall occur
(subject to compliance with Sections 2.02, 2.03 or 2.04) upon the earlier of (a)
the occurrence of a default or imminent default with respect to such loan and
(b) receipt by the Trustee of an Opinion of Counsel to the effect that

                                      70
<PAGE>

such repurchase or substitution, as applicable, will not result in the events
described in clause (i) or clause (ii) of the preceding sentence.

               (b) Upon discovery by the Depositor, either Seller, the Master
Servicer or the Trustee that any Mortgage Loan does not constitute a "qualified
mortgage" within the meaning of section 860G(a)(3) of the Code, the party
discovering such fact shall promptly (and in any event within 5 Business Days of
discovery) give written notice thereof to the other parties and the NIM Insurer.
In connection therewith, the Trustee shall require CHL, at CHL's option, to
either (i) substitute, if the conditions in Section 2.03(d) with respect to
substitutions are satisfied, a Replacement Mortgage Loan for the affected
Mortgage Loan, or (ii) repurchase the affected Mortgage Loan within 90 days of
such discovery in the same manner as it would a Mortgage Loan for a breach of
representation or warranty contained in Section 2.03. The Trustee shall reconvey
to CHL the Mortgage Loan to be released pursuant hereto in the same manner, and
on the same terms and conditions, as it would a Mortgage Loan repurchased for
breach of a representation or warranty contained in Section 2.03.

               Section 2.06  Authentication and Delivery of Certificates.

               The Trustee acknowledges the transfer and assignment to it of the
Trust Fund and, concurrently with such transfer and assignment, has executed,
authenticated and delivered, to or upon the order of the Depositor, the
Certificates in authorized denominations evidencing the entire ownership of the
Trust Fund. The Trustee agrees to hold the Trust Fund and exercise the rights
referred to above for the benefit of all present and future Holders of the
Certificates and to perform the duties set forth in this Agreement to the best
of its ability, to the end that the interests of the Holders of the Certificates
may be adequately and effectively protected.

               Section 2.07  Covenants of the Master Servicer.

               The Master Servicer hereby covenants to the Depositor and the
Trustee as follows:

               (a) the Master Servicer shall comply in the performance of its
obligations under this Agreement with all reasonable rules and requirements of
the insurer under each Required Insurance Policy; and

               (b) no written information, certificate of an officer, statement
furnished in writing or written report delivered to the Depositor, any affiliate
of the Depositor or the Trustee and prepared by the Master Servicer pursuant to
this Agreement will contain any untrue statement of a material fact or omit to
state a material fact necessary to make the information, certificate, statement
or report not misleading.

                                 ARTICLE III.
                ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

               Section 3.01  Master Servicer to Service Mortgage Loans.

               For and on behalf of the Certificateholders, the Master Servicer
shall service and administer the Mortgage Loans in accordance with customary and
usual standards of practice of

                                      71
<PAGE>

prudent mortgage loan lenders in the respective states in which the Mortgaged
Properties are located, including taking all required and appropriate actions
under each Required Insurance Policy and taking all required and appropriate
actions under the Mortgage Insurance Policy on behalf of the Co-Trustee, other
than the payment of the Mortgage Insurance Premium and obtaining the approval
of the Mortgage Insurer with respect to the appointment of a successor
servicer. In connection with such servicing and administration, the Master
Servicer shall have full power and authority, acting alone and/or through
subservicers as provided in Section 3.02 hereof, subject to the terms hereof
(i) to execute and deliver, on behalf of the Certificateholders and the
Trustee, customary consents or waivers and other instruments and documents,
(ii) to consent to transfers of any Mortgaged Property and assumptions of the
Mortgage Notes and related Mortgages (but only in the manner provided in this
Agreement), (iii) to collect any Insurance Proceeds, other Liquidation
Proceeds and Subsequent Recoveries and (iv) subject to Section 3.12(b), to
effectuate foreclosure or other conversion of the ownership of the Mortgaged
Property securing any Mortgage Loan; provided that the Master Servicer shall
take no action that is inconsistent with or prejudices the interests of the
Trustee or the Certificateholders in any Mortgage Loan or the rights and
interests of the Depositor and the Trustee under this Agreement. The Master
Servicer shall represent and protect the interest of the Trustee in the same
manner as it currently protects its own interest in mortgage loans in its own
portfolio in any claim, proceeding or litigation regarding a Mortgage Loan and
shall not make or permit any modification, waiver or amendment of any term of
any Mortgage Loan which would (i) cause any REMIC formed hereunder to fail to
qualify as a REMIC, (ii) result in the imposition of any tax under section
860(a) or 860(d) of the Code or (iii) cause any Covered Mortgage Loan to not
be covered by the Mortgage Insurance Policy, but in any case the Master
Servicer shall not act in any manner that is a lesser standard than that
provided in the first sentence of this Section 3.01. Without limiting the
generality of the foregoing, the Master Servicer, in its own name or in the
name of the Depositor and the Trustee, is hereby authorized and empowered by
the Depositor and the Trustee, when the Master Servicer believes it
appropriate in its reasonable judgment, to execute and deliver, on behalf of
the Trustee, the Depositor, the Certificateholders or any of them, any and all
instruments of satisfaction or cancellation, or of partial or full release or
discharge and all other comparable instruments, with respect to the Mortgage
Loans, and with respect to the Mortgaged Properties held for the benefit of
the Certificateholders. The Master Servicer shall prepare and deliver to the
Depositor and/or the Trustee such documents requiring execution and delivery
by any or all of them as are necessary or appropriate to enable the Master
Servicer to service and administer the Mortgage Loans. Upon receipt of such
documents, the Depositor and/or the Trustee shall execute such documents and
deliver them to the Master Servicer. The Master Servicer further is authorized
and empowered by the Trustee, on behalf of the Certificateholders and the
Trustee, in its own name or in the name of the Subservicer, when the Master
Servicer or the Subservicer, as the case may be, believes it appropriate in
its best judgment to register any Mortgage Loan on the MERS(R) System, or
cause the removal from the registration of any Mortgage Loan on the MERS(R)
System, to execute and deliver, on behalf of the Trustee and the
Certificateholders or any of them, any and all instruments of assignment and
other comparable instruments with respect to such assignment or re-recording
of a Mortgage in the name of MERS, solely as nominee for the Trustee and its
successors and assigns.

               In accordance with the standards of the preceding paragraph, the
Master Servicer shall advance or cause to be advanced funds as necessary for the
purpose of effecting the payment of taxes and assessments on the Mortgaged
Properties, which advances shall be

                                      72
<PAGE>

reimbursable in the first instance from related collections from the
Mortgagors pursuant to Section 3.06, and further as provided in Section 3.08.
All costs incurred by the Master Servicer, if any, in effecting the timely
payments of taxes and assessments on the Mortgaged Properties and related
insurance premiums shall not, for the purpose of calculating monthly
distributions to the Certificateholders, be added to the Stated Principal
Balance under the related Mortgage Loans, notwithstanding that the terms of
such Mortgage Loans so permit.

               The Master Servicer shall deliver a list of Servicing Officers
to the Trustee by the Closing Date.

               In addition, the Master Servicer shall administer the Mortgage
Insurance Policy on behalf of itself, the Sellers, the Depositor, and the
Trustee for the benefit of the Certificateholders, when it is necessary to make
claims and receive payments under the Mortgage Insurance Policy. In connection
with its activities as Master Servicer of the Mortgage Loans, the Master
Servicer agrees to present, on behalf of itself, the Trustee and the
Certificateholders, claims to the insurer under any primary insurance policies
and, in this regard, to take any reasonable action necessary to permit recovery
under any primary insurance policies respecting defaulted Mortgage Loans. Any
amounts collected by the Master Servicer under any primary insurance policies
shall be deposited in the Certificate Account.

               The Master Servicer shall take whatever action is appropriate to
maximize the amounts payable under the Mortgage Insurance Policy and to service
the Covered Mortgage Loans in the manner required by the Mortgage Insurance
Policy. The Master Servicer shall prepare and submit all claims eligible for
submission under the Mortgage Insurance Policies and shall perform all of the
obligations of the insured under the Mortgage Insurance Policy. If the Mortgage
Insurance Policy is terminated for any reason other than the exhaustion of its
coverage, or if the financial strength rating of its issuer is reduced to below
investment grade, the Master Servicer will use its best efforts to obtain a
comparable policy from an insurer that is acceptable to the Rating Agencies. The
replacement policy will provide coverage equal to the then remaining coverage of
the applicable Mortgage Insurance Policy, if available. However, if the premium
cost of a replacement policy exceeds the premium cost of the Mortgage Insurance
Policy, the coverage amount of the replacement policy will be reduced so that
its premium cost will not exceed the premium cost of the Mortgage Insurance
Policy.

               In the event that a shortfall in any collection on or liability
with respect to any Mortgage Loan results from or is attributable to adjustments
to Mortgage Rates, Scheduled Payments or Stated Principal Balances that were
made by the Master Servicer in a manner not consistent with the terms of the
related Mortgage Note and this Agreement, the Master Servicer, upon discovery or
receipt of notice thereof, immediately shall deliver to the Trustee for deposit
in the Distribution Account from its own funds the amount of any such shortfall
and shall indemnify and hold harmless the Trust Fund, the Trustee, the Depositor
and any successor master servicer in respect of any such liability. Such
indemnities shall survive the termination or discharge of this Agreement.
Notwithstanding the foregoing, this Section 3.01 shall not limit the ability of
the Master Servicer to seek recovery of any such amounts from the related
Mortgagor under the terms of the related Mortgage Note, as permitted by law and
shall not be an expense of the Trust.

                                      73

               Section 3.02 Subservicing; Enforcement of the Obligations of
Master Servicer.

               (a) The Master Servicer may arrange for the subservicing of any
Mortgage Loan by a subservicer (each, a "Subservicer") pursuant to a
subservicing agreement (each, a "Subservicing Agreement"); provided that (i)
such subservicing arrangement and the terms of the related subservicing
agreement must provide for the servicing of such Mortgage Loans in a manner
consistent with the servicing arrangements contemplated hereunder, (ii) that
such subservicing agreements would not result in a withdrawal or a downgrading
by any Rating Agency of the ratings on any Class of Certificates, as evidenced
by a letter to that effect delivered by each Rating Agency to the Depositor and
the NIM Insurer and (iii) the NIM Insurer shall have consented to such
subservicing agreements (which consent shall not be unreasonably withheld) with
Subservicers, for the servicing and administration of the Mortgage Loans. The
Master Servicer shall deliver to the Trustee copies of all Sub-Servicing
Agreements, and any amendments or modifications thereof, promptly upon the
Master Servicer's execution and delivery of such instruments. The Master
Servicer, with the written consent of the NIM Insurer (which consent shall not
be unreasonably withheld), shall be entitled to terminate any Subservicing
Agreement and the rights and obligations of any Subservicer pursuant to any
Subservicing Agreement in accordance with the terms and conditions of such
Subservicing Agreement. Notwithstanding the provisions of any subservicing
agreement, any of the provisions of this Agreement relating to agreements or
arrangements between the Master Servicer or a subservicer or reference to
actions taken through a Master Servicer or otherwise, the Master Servicer shall
remain obligated and liable to the Depositor, the Trustee and the
Certificateholders for the servicing and administration of the Mortgage Loans in
accordance with the provisions of this Agreement without diminution of such
obligation or liability by virtue of such subservicing agreements or
arrangements or by virtue of indemnification from the subservicer and to the
same extent and under the same terms and conditions as if the Master Servicer
alone were servicing and administering the Mortgage Loans. Every subservicing
agreement entered into by the Master Servicer shall contain a provision giving
the successor Master Servicer the option to terminate such agreement without
cost in the event a successor Master Servicer is appointed. All actions of each
subservicer performed pursuant to the related subservicing agreement shall be
performed as an agent of the Master Servicer with the same force and effect as
if performed directly by the Master Servicer.

               (b) For purposes of this Agreement, the Master Servicer shall be
deemed to have received any collections, recoveries or payments with respect to
the Mortgage Loans that are received by a subservicer regardless of whether such
payments are remitted by the subservicer to the Master Servicer.

               Section 3.03  Rights of the Depositor, the Sellers, the
                             Certificateholders, the NIM Insurer and the Trustee
                             in Respect of the Master Servicer.

               None of the Trustee, the Sellers, the Certificateholders, the NIM
Insurer or the Depositor shall have any responsibility or liability for any
action or failure to act by the Master Servicer, and none of them is obligated
to supervise the performance of the Master Servicer hereunder or otherwise. The
Master Servicer shall afford (and any Subservicing Agreement shall provide that
each Subservicer shall afford) the Depositor, the NIM Insurer and the Trustee,
upon reasonable notice, during normal business hours, access to all records
maintained by the

                                      74

Master Servicer (and any such Subservicer) in respect of the Master Servicer's
rights and obligations hereunder and access to officers of the Master Servicer
(and those of any such Subservicer) responsible for such obligations. Upon
request, the Master Servicer shall furnish to the Depositor, the NIM Insurer
and the Trustee its (and any such Subservicer's) most recent financial
statements and such other information relating to the Master Servicer's
capacity to perform its obligations under this Agreement that it possesses. To
the extent such information is not otherwise available to the public, the
Depositor, the NIM Insurer and the Trustee shall not disseminate any
information obtained pursuant to the preceding two sentences without the
Masters Servicer's (or any such Subservicer's) written consent, except as
required pursuant to this Agreement or to the extent that it is necessary to
do so (i) in working with legal counsel, auditors, taxing authorities or other
governmental agencies, rating agencies or reinsurers or (ii) pursuant to any
law, rule, regulation, order, judgment, writ, injunction or decree of any
court or governmental authority having jurisdiction over the Depositor, the
Trustee, the NIM Insurer or the Trust Fund, and in either case, the Depositor,
the NIM Insurer or the Trustee, as the case may be, shall use its reasonable
best efforts to assure the confidentiality of any such disseminated non-public
information. The Depositor may, but is not obligated to, enforce the
obligations of the Master Servicer under this Agreement and may, but is not
obligated to, perform, or cause a designee to perform, any defaulted
obligation of the Master Servicer under this Agreement or exercise the rights
of the Master Servicer under this Agreement; provided by virtue of such
performance by the Depositor of its designee. The Depositor shall not have any
responsibility or liability for any action or failure to act by the Master
Servicer and is not obligated to supervise the performance of the Master
Servicer under this Agreement or otherwise.

               Section 3.04  Trustee to Act as Master Servicer.

               In the event that the Master Servicer shall for any reason no
longer be the Master Servicer hereunder (including by reason of an Event of
Default), the Trustee or its designee shall thereupon assume all of the rights
and obligations of the Master Servicer hereunder arising thereafter (except that
the Trustee shall not be (i) liable for losses of the Master Servicer pursuant
to Section 3.10 hereof or any acts or omissions of the predecessor Master
Servicer hereunder, (ii) obligated to make Advances if it is prohibited from
doing so by applicable law, (iii) obligated to effectuate repurchases or
substitutions of Mortgage Loans hereunder, including pursuant to Section 2.02 or
2.03 hereof, (iv) responsible for expenses of the Master Servicer pursuant to
Section 2.03 or (v) deemed to have made any representations and warranties
hereunder, including pursuant to Section 2.03 or the first paragraph of Section
6.02 hereof). If the Master Servicer shall for any reason no longer be the
Master Servicer (including by reason of any Event of Default), the Trustee (or
any other successor servicer) may, at its option, succeed to any rights and
obligations of the Master Servicer under any subservicing agreement in
accordance with the terms thereof; provided that the Trustee (or any other
successor servicer) shall not incur any liability or have any obligations in its
capacity as servicer under a subservicing agreement arising prior to the date of
such succession unless it expressly elects to succeed to the rights and
obligations of the Master Servicer thereunder; and the Master Servicer shall not
thereby be relieved of any liability or obligations under the subservicing
agreement arising prior to the date of such succession.

               The Master Servicer shall, upon request of the Trustee, but at
the expense of the Master Servicer, deliver to the assuming party all documents
and records relating to each

                                      75

subservicing agreement and the Mortgage Loans then being serviced thereunder
and an accounting of amounts collected held by it and otherwise use its best
efforts to effect the orderly and efficient transfer of the subservicing
agreement to the assuming party.

               Section 3.05  Collection of Mortgage Loan Payments;
                             Certificate Account; Distribution Account;
                             Pre-Funding Account; Seller Shortfall Interest
                             Requirement.

               (a)    The Master Servicer shall make reasonable efforts in
accordance with customary and usual standards of practice of prudent mortgage
lenders in the respective states in which the Mortgaged Properties are located
to collect all payments called for under the terms and provisions of the
Mortgage Loans to the extent such procedures shall be consistent with this
Agreement and the terms and provisions of any related Required Insurance Policy.
Consistent with the foregoing, the Master Servicer may in its discretion (i)
waive any late payment charge or, subject to Section 3.20, any Prepayment Charge
or penalty interest in connection with the prepayment of a Mortgage Loan and
(ii) extend the due dates for payments due on a Mortgage Note for a period not
greater than 270 days. In the event of any such arrangement, the Master Servicer
shall make Advances on the related Mortgage Loan during the scheduled period in
accordance with the amortization schedule of such Mortgage Loan without
modification thereof by reason of such arrangements. In addition, the NIM
Insurer's prior written consent shall be required for any waiver of Prepayment
Charges or for the extension of the due dates for payments due on a Mortgage
Note, if the aggregate number of outstanding Mortgage Loans that have been
granted such waivers or extensions exceeds 5% of the aggregate number of Initial
Mortgage Loans and Subsequent Mortgage Loans. The Master Servicer shall not be
required to institute or join in litigation with respect to collection of any
payment (whether under a Mortgage, Mortgage Note or otherwise or against any
public or governmental authority with respect to a taking or condemnation) if it
reasonably believes that enforcing the provision of the Mortgage or other
instrument pursuant to which such payment is required is prohibited by
applicable law.

               (b)    The Master Servicer shall establish and maintain a
Certificate Account into which the Master Servicer shall deposit or cause to be
deposited on a daily basis within two Business Days of receipt, except as
otherwise specifically provided herein, the following payments and collections
remitted by Subservicers or received by it in respect of Mortgage Loans
subsequent to the Cut-off Date (other than in respect of principal and interest
due on the Mortgage Loans before the Cut-off Date) and the following amounts
required to be deposited hereunder:

                      (1) all payments on account of principal, including
        Principal Prepayments, on the Mortgage Loans;

                      (2) all payments on account of interest on the Mortgage
        Loans (net of the related Servicing Fee and Prepayment Interest Excess
        permitted under Section 3.15 hereof to the extent not previously paid to
        or withheld by the Master Servicer);

                      (3) all Insurance Proceeds;

                                      76
<PAGE>

                      (4) all Liquidation Proceeds and Subsequent Recoveries,
        other than proceeds to be applied to the restoration or repair of the
        Mortgaged Property or released to the Mortgagor in accordance with the
        Master Servicer's normal servicing procedures;

                      (5) all Compensating Interest;

                      (6) any amount required to be deposited by the Master
        Servicer pursuant to Section 3.05(e) in connection with any losses on
        Permitted Investments;

                      (7) any amounts required to be deposited by the Master
        Servicer pursuant to Section 3.10 hereof;

                      (8) the Purchase Price and any Substitution Adjustment
        Amount;

                      (9) all Advances made by the Master Servicer or the
        Trustee pursuant to Section 4.01 hereof;

                     (10) all Prepayment Charges and Master Servicer Prepayment
        Charge Payment Amounts; and

                     (11) any other amounts required to be deposited hereunder.

               The foregoing requirements for remittance by the Master Servicer
into the Certificate Account shall be exclusive, it being understood and agreed
that, without limiting the generality of the foregoing, payments in the nature
of late payment charges or assumption fees, if collected, need not be remitted
by the Master Servicer. In the event that the Master Servicer shall remit any
amount not required to be remitted and not otherwise subject to withdrawal
pursuant to Section 3.08 hereof, it may at any time withdraw or direct the
institution maintaining the Certificate Account, to withdraw such amount from
the Certificate Account, any provision herein to the contrary notwithstanding.
Such withdrawal or direction may be accomplished by delivering written notice
thereof to the institution maintaining the Certificate Account, that describes
the amounts deposited in error in the Certificate Account. The Master Servicer
shall maintain adequate records with respect to all withdrawals made pursuant to
this Section. All funds deposited in the Certificate Account shall be held in
trust for the Certificateholders until withdrawn in accordance with Section
3.08.

               No later than 1:00 p.m. Pacific time on the Business Day prior to
the Master Servicer Advance Date in each of January 2005, February 2005 and
March 2005, CHL shall remit to the Master Servicer, and the Master Servicer
shall deposit in the Certificate Account, the Seller Shortfall Interest
Requirement (if any) for such Master Servicer Advance Date.

               (c)    The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Distribution Account. The Trustee shall, promptly upon
receipt, deposit in the Distribution Account and retain therein the following:

                      (1) the aggregate amount remitted by the Master Servicer
        pursuant to the second paragraph of Section 3.08(a); and

                                      77
<PAGE>

                      (2) any amount required to be deposited by the Master
        Servicer pursuant to Section 3.05(e) in connection with any losses on
        Permitted Investments.

               The foregoing requirements for remittance by the Master Servicer
and deposit by the Trustee into the Distribution Account shall be exclusive. In
the event that the Master Servicer shall remit any amount not required to be
remitted and not otherwise subject to withdrawal pursuant to Section 3.08
hereof, it may at any time direct the Trustee to withdraw such amount from the
Distribution Account, any provision herein to the contrary notwithstanding. Such
direction may be accomplished by delivering a written notice to the Trustee that
describes the amounts deposited in error in the Distribution Account. All funds
deposited in the Distribution Account shall be held by the Trustee in trust for
the Certificateholders until disbursed in accordance with this Agreement or
withdrawn in accordance with Section 3.08. In no event shall the Trustee incur
liability for withdrawals from the Distribution Account at the direction of the
Master Servicer.

               (d) The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Pre-Funding Account. On the Closing Date, CHL shall
remit the Pre-Funded Amount to the Trustee for deposit in the Pre-Funding
Account.

               On the Business Day before the Distribution Date following the
end of the Funding Period, the Trustee shall (i) withdraw the amount on deposit
in the Pre-Funding Account (net of investment income), (ii) promptly deposit
such amount in the Distribution Account, and (iii) distribute each amount to the
Certificates on the Distribution Date pursuant to Section 4.04.

               No later than 1:00 p.m. Pacific time on the Business Day prior to
the Master Servicer Advance Date in January 2005, February 2005 and March 2005,
CHL on behalf of the Sellers shall remit to the Master Servicer, and the Master
Servicer shall deposit in the Certificate Account, the Seller Shortfall Interest
Requirement (if any) for such Master Servicer Advance Date.

               (e) Each institution that maintains the Certificate Account, the
Distribution Account or the Pre-Funding Account shall invest the funds in each
such account, as directed by the Master Servicer, in Permitted Investments,
which shall mature not later than (x) in the case of the Certificate Account,
the second Business Day next preceding the related Distribution Account Deposit
Date (except that if such Permitted Investment is an obligation of the
institution that maintains such Certificate Account, then such Permitted
Investment shall mature not later than the Business Day next preceding such
Distribution Account Deposit Date) and (y) in the case of the Distribution
Account and the Pre-Funding Account, the Business Day immediately preceding the
first Distribution Date that follows the date of such investment (except that if
such Permitted Investment is an obligation of the institution that maintains
such Distribution Account or Pre-Funding Account, then such Permitted Investment
shall mature not later than such Distribution Date), in each case, shall not be
sold or disposed of prior to its maturity. All such Permitted Investments shall
be made in the name of the Trustee, for the benefit of the Certificateholders.
In the case of (i) the Certificate Account and the Distribution Account, all
income and gain net of any losses realized from any such investment shall be for
the benefit of the Master Servicer as servicing compensation and shall be
remitted to it monthly as provided

                                      78
<PAGE>

herein and (ii) the Pre-Funding Account, all income and gain net of any losses
realized from any such investment shall be for the benefit of CHL and shall be
remitted to CHL as provided herein. The amount of any losses incurred in the
Certificate Account or the Distribution Account in respect of any such
investments shall be deposited by the Master Servicer in the Certificate
Account or paid to the Trustee for deposit into the Distribution Account out
of the Master Servicer's own funds immediately as realized. The amount of any
losses incurred in the Pre-Funding Account in respect of any such investments
shall be paid by CHL to the Trustee for deposit into the Pre-Funding Account
out of CHL's own funds immediately as realized. The Trustee shall not be
liable for the amount of any loss incurred in respect of any investment or
lack of investment of funds held in the Certificate Account, the Distribution
Account or the Pre-Funding Account and made in accordance with this Section
3.05.

               (f) The Master Servicer shall give at least 30 days advance
notice to the Trustee, each Seller, each Rating Agency and the Depositor of any
proposed change of location of the Certificate Account prior to any change
thereof. The Trustee shall give at least 30 days advance notice to the Master
Servicer, each Seller, each Rating Agency and the Depositor of any proposed
change of the location of the Distribution Account, the Pre-Funding Account or
the Carryover Reserve Fund prior to any change thereof.

               (g) Except as otherwise expressly provided in this Agreement, if
any default occurs under any Permitted Investment, the Trustee may and, subject
to Sections 8.01 and 8.02(a)(4), at the request of the Holders of Certificates
representing more than 50% of the Voting Rights or the NIM Insurer, shall take
any action appropriate to enforce payment or performance, including the
institution and prosecution of appropriate proceedings.

               Section 3.06  Collection of Taxes, Assessments and Similar
                             Items; Escrow Accounts.

               To the extent required by the related Mortgage Note, the Master
Servicer shall establish and maintain one or more accounts (each, an "Escrow
Account") and deposit and retain therein all collections from the Mortgagors (or
advances by the Master Servicer) for the payment of taxes, assessments, hazard
insurance premiums or comparable items for the account of the Mortgagors.
Nothing herein shall require the Master Servicer to compel a Mortgagor to
establish an Escrow Account in violation of applicable law.

               Withdrawals of amounts so collected from the Escrow Accounts may
be made only to effect timely payment of taxes, assessments, hazard insurance
premiums, condominium or PUD association dues, or comparable items, to reimburse
the Master Servicer out of related collections for any payments made pursuant to
Sections 3.01 hereof (with respect to taxes and assessments and insurance
premiums) and 3.10 hereof (with respect to hazard insurance), to refund to any
Mortgagors any sums as may be determined to be overages, to pay interest, if
required by law or the terms of the related Mortgage or Mortgage Note, to
Mortgagors on balances in the Escrow Account or to clear and terminate the
Escrow Account at the termination of this Agreement in accordance with Section
9.01 hereof. The Escrow Accounts shall not be a part of the Trust Fund.

               The Master Servicer shall afford the Depositor, the NIM Insurer
and the Trustee reasonable access to all records and documentation regarding the
Mortgage Loans and all accounts, insurance policies and other matters relating
to this Agreement, such access being afforded without charge, but only upon
reasonable request and during normal business hours at the offices of the Master
Servicer designated by it. Upon request, the Master Servicer shall furnish to
the Trustee and the NIM Insurer its most recent publicly available financial
statements and any other information relating to its capacity to perform its
obligations under this Agreement reasonably requested by the NIM Insurer.

               Upon reasonable advance notice in writing if required by federal
regulation, the Master Servicer will provide to each Certificateholder or
Certificate Owner that is a savings and loan association, bank or insurance
company certain reports and reasonable access to information and documentation
regarding the Mortgage Loans sufficient to permit such Certificateholder or
Certificate Owner to comply with applicable regulations of the OTS or other
regulatory authorities with respect to investment in the Certificates; provided
that the Master Servicer shall be entitled to be reimbursed by each such
Certificateholder or Certificate Owner for actual expenses incurred by the
Master Servicer in providing such reports and access.

               Section 3.08  Permitted Withdrawals from the Certificate
                             Account, Distribution Account, Carryover Reserve

               (a)    The Master Servicer may from time to time make
withdrawals from the Certificate Account for the following purposes:

                      (i) to pay to the Master Servicer (to the extent not
               previously paid to or withheld by the Master Servicer), as
               servicing compensation in accordance with Section 3.15, that
               portion of any payment of interest that equals the Servicing Fee
               for the period with respect to which such interest payment was
               made, and, as additional servicing compensation to the Master
               Servicer, those other amounts set forth in Section 3.15;

                      (ii) to reimburse each of the Master Servicer and the
               Trustee for Advances made by it with respect to the Mortgage

               (ii) being limited to amounts received on particular Mortgage
               Loan(s) (including, for this purpose, Liquidation Proceeds,
               Insurance Proceeds and Subsequent Recoveries) that represent late
               recoveries of payments of principal and/or interest on such
               particular Mortgage Loan(s) in respect of which any such Advance
               was made;

                      (vi) to pay the Master Servicer any unpaid Servicing Fees
               and to reimburse it for any unreimbursed Servicing Advances, the
               Master Servicer's right to reimbursement of Servicing Advances

               amounts received thereon and not taken into account in
               determining the related Stated Principal Balance of such
               repurchased Mortgage Loan;

                      (viii) to reimburse the applicable Seller, the Master
               Servicer, the NIM Insurer or the Depositor for expenses incurred
               by any of them in connection with the Mortgage Loans or
               Certificates and reimbursable pursuant to Section 6.03 hereof;
               provided that such amount shall only be withdrawn following the

               deposited therein; and

                      (xi) to clear and terminate the Certificate Account upon
               termination of this Agreement pursuant to Section 9.01 hereof.

               In addition, no later than 1:00 p.m. Pacific time on the

               The Trustee shall establish and maintain, on behalf of the
Certificateholders, a Principal Reserve Fund in the name of the Trustee. On the

on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Certificate Account pursuant to subclauses (i), (ii), (iv),
(v), (vi), (vii) and (viii) above. Prior to making any withdrawal from the
Certificate Account pursuant to subclause (iv), the Master Servicer shall
deliver to the Trustee an Officer's Certificate of a Servicing Officer
indicating the amount of any previous Advance determined by the Master Servicer
to be a Nonrecoverable Advance and identifying the related Mortgage Loan(s), and
their respective portions of such Nonrecoverable Advance.

Account for distribution to the Certificateholders in the manner specified in
this Agreement (and to withhold from the amounts so withdrawn, the amount of any

                      (i) to pay the Trustee the Trustee Fee on each
               Distribution Date;

                      (ii) to pay to the Master Servicer, as additional
               servicing compensation, earnings on or investment income with
               respect to funds in or credited to the Distribution Account;

                      (iii) to withdraw pursuant to Section 3.05 any amount
               deposited in the Distribution Account and not required to be
               deposited therein;

                      (iv) to reimburse the Trustee for any unreimbursed
               Advances made by it pursuant to Section 4.01(d) hereof, such
               right of reimbursement pursuant to this subclause (iv) being
               limited to (x) amounts received on the related Mortgage Loan(s)
               in respect of which any such Advance was made and (y) amounts not
               otherwise reimbursed to the Trustee pursuant to Section
               3.08(a)(ii) hereof;

                      (v) to reimburse the Trustee for any Nonrecoverable
               Advance previously made by the Trustee pursuant to Section
               4.01(d) hereof, such right of reimbursement pursuant to this
               subclause (v) being limited to amounts not otherwise reimbursed
               to the Trustee pursuant to Section 3.08(a)(iv) hereof; and

                      (vi) to pay to the Co-Trustee, for payment to the Mortgage
               Insurer as provided below, the Mortgage Insurance Premium;

                      (vii) to clear and terminate the Distribution Account upon
               termination of the Agreement pursuant to Section 9.01 hereof.

               The Co-Trustee shall pay the applicable Mortgage Insurance
Premium to the Mortgage Insurer in accordance with the following wiring

               (c) The Trustee shall withdraw funds from the Carryover Reserve
Fund for distribution to the Certificateholders in the manner specified in this
Agreement (and to withhold from the amounts so withdrawn, the amount of any
taxes that it is authorized to retain pursuant to the penultimate paragraph of
Section 8.11). In addition, the Trustee may from time to time make withdrawals
from the Carryover Reserve Fund for the following purposes:

                      (1) to withdraw any amount deposited in the Carryover
        Reserve Fund and not required to be deposited therein; and

                      (2) to clear and terminate the Carryover Reserve Fund upon
        termination of the Agreement pursuant to Section 9.01 hereof.

               Section 3.09  [Reserved]

               Section 3.10  Maintenance of Hazard Insurance.

               The Master Servicer shall cause to be maintained, for each
Mortgage Loan, hazard insurance with extended coverage in an amount that is at
least equal to the lesser of (i) the maximum insurable value of the improvements
securing such Mortgage Loan and (ii) the greater of (a) the outstanding
principal balance of the Mortgage Loan and (b) an amount such that the proceeds
of such policy shall be sufficient to prevent the related Mortgagor and/or
mortgagee from becoming a co-insurer. Each such policy of standard hazard
insurance shall contain, or have an accompanying endorsement that contains, a
standard mortgagee clause. The Master Servicer shall also cause flood insurance
to be maintained on property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan, to the extent described below. Pursuant to
Section 3.05 hereof, any amounts collected by the Master Servicer under any such
policies (other than the amounts to be applied to the restoration or repair of
the related Mortgaged Property or property thus acquired or amounts released to
the Mortgagor in accordance with the Master Servicer's normal servicing
procedures) shall be deposited in the Certificate Account. Any cost incurred by
the Master Servicer in maintaining any such insurance shall not, for the purpose
of calculating monthly distributions to the Certificateholders or remittances to
the Trustee for their benefit, be added to the principal balance of the Mortgage
Loan, notwithstanding that the terms of the Mortgage Loan so permit. Such costs
shall be recoverable by the Master Servicer out of late payments by the related
Mortgagor or out of Liquidation Proceeds or Subsequent Recoveries to the extent
permitted by Section 3.08 hereof. It is understood and agreed that no earthquake
or other additional insurance is to be required of any Mortgagor or maintained
on property acquired in respect of a Mortgage other than pursuant to such
applicable laws and regulations as shall at any time be in force and as shall
require such additional insurance. If the Mortgaged Property is

                                      83
<PAGE>

located at the time of origination of the Mortgage Loan in a federally
designated special flood hazard area and such area is participating in the
national flood insurance program, the Master Servicer shall cause flood
insurance to be maintained with respect to such Mortgage Loan. Such flood
insurance shall be in an amount equal to the lesser of (i) the original
principal balance of the related Mortgage Loan, (ii) the replacement value of
the improvements that are part of such Mortgaged Property, or (iii) the
maximum amount of such insurance available for the related Mortgaged Property
under the Flood Disaster Protection Act of 1973, as amended.

               Section 3.11  Enforcement of Due-On-Sale Clauses; Assumption
                             Agreements.

               (a) Except as otherwise provided in this Section 3.11(a), when
any property subject to a Mortgage has been or is about to be conveyed by the
Mortgagor, the Master Servicer shall to the extent that it has knowledge of such
conveyance, enforce any due-on-sale clause contained in any Mortgage Note or
Mortgage, to the extent permitted under applicable law and governmental
regulations, but only to the extent that such enforcement will not adversely
affect or jeopardize coverage under any Required Insurance Policy.
Notwithstanding the foregoing, the Master Servicer is not required to exercise
such rights with respect to a Mortgage Loan if the Person to whom the related
Mortgaged Property has been conveyed or is proposed to be conveyed satisfies the
terms and conditions contained in the Mortgage Note and Mortgage related thereto
and the consent of the mortgagee under such Mortgage Note or Mortgage is not
otherwise so required under such Mortgage Note or Mortgage as a condition to
such transfer. In the event that the Master Servicer is prohibited by law from
enforcing any such due-on-sale clause, or if coverage under any Required
Insurance Policy would be adversely affected, or if nonenforcement is otherwise
permitted hereunder, the Master Servicer is authorized, subject to Section
3.11(b), to take or enter into an assumption and modification agreement from or
with the person to whom such property has been or is about to be conveyed,
pursuant to which such person becomes liable under the Mortgage Note and, unless
prohibited by applicable state law, the Mortgagor remains liable thereon,
provided that the Mortgage Loan shall continue to be covered (if so covered
before the Master Servicer enters such agreement) by the applicable Required
Insurance Policies. The Master Servicer, subject to Section 3.11(b), is also
authorized with the prior approval of the insurers under any Required Insurance
Policies to enter into a substitution of liability agreement with such Person,
pursuant to which the original Mortgagor is released from liability and such
Person is substituted as Mortgagor and becomes liable under the Mortgage Note.
The Master Servicer shall notify the Trustee that any such substitution,
modification or assumption agreement has been completed by forwarding to the
Co-Trustee the executed original of such substitution or assumption agreement,
which document shall be added to the related Mortgage File and shall, for all
purposes, be considered a part of such Mortgage File to the same extent as all
other documents and instruments constituting a part thereof.

               (b) Subject to the Master Servicer's duty to enforce any
due-on-sale clause to the extent set forth in Section 3.11(a) hereof, in any
case in which a Mortgaged Property has been conveyed to a Person by a Mortgagor,
and such Person is to enter into an assumption agreement or modification
agreement or supplement to the Mortgage Note or Mortgage that requires the
signature of the Trustee, or if an instrument of release signed by the Trustee
is required releasing the Mortgagor from liability on the Mortgage Loan, the
Master Servicer shall prepare and deliver or cause to be prepared and delivered
to the Trustee for signature and shall direct, in writing, the Trustee to
execute the assumption agreement with the Person to whom the

                                      84
<PAGE>

Mortgaged Property is to be conveyed and such modification agreement or
supplement to the Mortgage Note or Mortgage or other instruments as are
reasonable or necessary to carry out the terms of the Mortgage Note or
Mortgage or otherwise to comply with any applicable laws regarding assumptions
or the transfer of the Mortgaged Property to such Person. In connection with
any such assumption, no material term of the Mortgage Note (including, but not
limited to, the Mortgage Rate, the amount of the Scheduled Payment, the
Maximum Mortgage Rate, the Minimum Mortgage Rate, the Gross Margin, the
Initial Periodic Rate Cap, the Subsequent Periodic Rate Cap, the Adjustment
Date and any other term affecting the amount or timing of payment on the
Mortgage Loan) may be changed. In addition, the substitute Mortgagor and the
Mortgaged Property must be acceptable to the Master Servicer in accordance
with its underwriting standards as then in effect. The Master Servicer shall
notify the Trustee that any such substitution or assumption agreement has been
completed by forwarding to the Trustee the original of such substitution or
assumption agreement, which in the case of the original shall be added to the
related Mortgage File and shall, for all purposes, be considered a part of
such Mortgage File to the same extent as all other documents and instruments
constituting a part thereof. Any fee collected by the Master Servicer for
entering into an assumption or substitution of liability agreement will be
retained by the Master Servicer as additional servicing compensation.

               Section 3.12  Realization Upon Defaulted Mortgage Loans;
                             Determination of Excess Proceeds and Realized
                             Losses; Repurchase of Certain Mortgage Loans.

               (a) The Master Servicer may agree to a modification of any
Mortgage Loan (the "Modified Mortgage Loan") if (i) the modification is in lieu
of a refinancing and (ii) the Mortgage Rate on the Modified Mortgage Loan is
approximately a prevailing market rate for newly-originated mortgage loans
having similar terms and (iii) the Master Servicer purchases the Modified
Mortgage Loan from the Trust Fund as described below. Effective immediately
after the modification, and, in any event, on the same Business Day on which the
modification occurs, all interest of the Trustee in the Modified Mortgage Loan
shall automatically be deemed transferred and assigned to the Master Servicer
and all benefits and burdens of ownership thereof, including the right to
accrued interest thereon from the date of modification and the risk of default
thereon, shall pass to the Master Servicer. The Master Servicer shall promptly
deliver to the Trustee a certification of a Servicing Officer to the effect that
all requirements of this paragraph have been satisfied with respect to the
Modified Mortgage Loan. For federal income tax purposes, the Trustee shall
account for such purchase as a prepayment in full of the Modified Mortgage Loan.
The Master Servicer shall deposit the Purchase Price for any Modified Mortgage
Loan in the Certificate Account pursuant to Section 3.05 within one Business Day
after the purchase of the Modified Mortgage Loan. Upon receipt by the Trustee of
written notification of any such deposit signed by a Servicing Officer, the
Trustee shall release to the Master Servicer the related Mortgage File and shall
execute and deliver such instruments of transfer or assignment, in each case
without recourse, as shall be necessary to vest in the Master Servicer any
Modified Mortgage Loan previously transferred and assigned pursuant hereto. The
Master Servicer covenants and agrees to indemnify the Trust Fund against any
liability for any "prohibited transaction" taxes and any related interest,
additions, and penalties imposed on the Trust Fund established hereunder as a
result of any modification of a Mortgage Loan effected pursuant to this
subsection (b), any holding of a Modified Mortgage Loan by the Trust Fund or

                                      85
<PAGE>

any purchase of a Modified Mortgage Loan by the Master Servicer (but such
obligation shall not prevent the Master Servicer or any other appropriate
Person from in good faith contesting any such tax in appropriate proceedings
and shall not prevent the Master Servicer from withholding payment of such
tax, if permitted by law, pending the outcome of such proceedings). The Master
Servicer shall have no right of reimbursement for any amount paid pursuant to
the foregoing indemnification, except to the extent that the amount of any
tax, interest, and penalties, together with interest thereon, is refunded to
the Trust Fund or the Master Servicer. If the Master Servicer agrees to a
modification of any Mortgage Loan pursuant to this Section 3.12(a), and if
such Mortgage Loan carries a Prepayment Charge provision, the Master Servicer
will deliver to the Trustee the amount of the Prepayment Charge, if any, that
would have been due had such Mortgage Loan been prepaid at the time of such
modification, for deposit into the Certificate Account (not later than 1:00
p.m. Pacific time on the Master Servicer Advance Date immediately succeeding
the date of such modification) for distribution in accordance with the terms
of this Agreement.

               (b) The Master Servicer shall use reasonable efforts to foreclose
upon or otherwise comparably convert the ownership of properties securing such
of the Mortgage Loans as come into and continue in default and as to which no
satisfactory arrangements can be made for collection of delinquent payments. In
connection with such foreclosure or other conversion, the Master Servicer shall
follow such practices and procedures as it shall deem necessary or advisable and
as shall be normal and usual in its general mortgage servicing activities and
the requirements of the insurer under any Required Insurance Policy; provided
that the Master Servicer shall not be required to expend its own funds in
connection with any foreclosure or towards the restoration of any property
unless it shall determine (i) that such restoration and/or foreclosure will
increase the proceeds of liquidation of the Mortgage Loan after reimbursement to
itself of such expenses and (ii) that such expenses will be recoverable to it
through Liquidation Proceeds (respecting which it shall have priority for
purposes of withdrawals from the Certificate Account pursuant to Section 3.08
hereof). The Master Servicer shall be responsible for all other costs and
expenses incurred by it in any such proceedings; provided that it shall be
entitled to reimbursement thereof from the proceeds of liquidation of the
related Mortgaged Property and any related Subsequent Recoveries, as
contemplated in Section 3.08 hereof. If the Master Servicer has knowledge that a
Mortgaged Property that the Master Servicer is contemplating acquiring in
foreclosure or by deed-in-lieu of foreclosure is located within a one-mile
radius of any site with environmental or hazardous waste risks known to the
Master Servicer, the Master Servicer will, prior to acquiring the Mortgaged
Property, consider such risks and only take action in accordance with its
established environmental review procedures.

               With respect to any REO Property, the deed or certificate of sale
shall be taken in the name of the Trustee for the benefit of the
Certificateholders (or the Trustee's nominee on behalf of the
Certificateholders). The Trustee's name shall be placed on the title to such REO
Property solely as the Trustee hereunder and not in its individual capacity. The
Master Servicer shall ensure that the title to such REO Property references this
Agreement and the Trustee's capacity thereunder. Pursuant to its efforts to sell
such REO Property, the Master Servicer shall either itself or through an agent
selected by the Master Servicer protect and conserve such REO Property in the
same manner and to such extent as is customary in the locality where such REO
Property is located and may, incident to its conservation and protection of the
interests of the Certificateholders, rent the same, or any part thereof, as the
Master Servicer deems to be in the

                                      86
<PAGE>

best interest of the Master Servicer and the Certificateholders for the period
prior to the sale of such REO Property. The Master Servicer shall prepare for
and deliver to the Trustee a statement with respect to each REO Property that
has been rented showing the aggregate rental income received and all expenses
incurred in connection with the management and maintenance of such REO
Property at such times as is necessary to enable the Trustee to comply with
the reporting requirements of the REMIC Provisions. The net monthly rental
income, if any, from such REO Property shall be deposited in the Certificate
Account no later than the close of business on each Determination Date. The
Master Servicer shall perform the tax reporting and withholding related to
foreclosures, abandonments and cancellation of indebtedness income as
specified by Sections 1445, 6050J and 6050P of the Code by preparing and
filing such tax and information returns, as may be required.

               In the event that the Trust Fund acquires any Mortgaged Property
as aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Master Servicer shall dispose of such Mortgaged Property as
soon as practicable in a manner that maximizes the Liquidation Proceeds, but in
no event later than three years after its acquisition by the Trust Fund or, at
the expense of the Trust Fund, the Master Servicer shall request, more than 60
days prior to the day on which such three-year period would otherwise expire, an
extension of the three-year grace period. In the event the Trustee shall have
been supplied with an Opinion of Counsel (such opinion not to be an expense of
the Trustee) to the effect that the holding by the Trust Fund of such Mortgaged
Property subsequent to such three-year period will not result in the imposition
of taxes on "prohibited transactions" of the Trust Fund as defined in section
860F of the Code or cause any REMIC formed hereunder to fail to qualify as a
REMIC at any time that any Certificates are outstanding, and the Trust Fund may
continue to hold such Mortgaged Property (subject to any conditions contained in
such Opinion of Counsel) after the expiration of such three-year period.
Notwithstanding any other provision of this Agreement, no Mortgaged Property
acquired by the Trust Fund shall be rented (or allowed to continue to be rented)
or otherwise used for the production of income by or on behalf of the Trust Fund
in such a manner or pursuant to any terms that would (i) cause such Mortgaged
Property to fail to qualify as "foreclosure property" within the meaning of
section 860G(a)(8) of the Code or (ii) subject the Trust Fund to the imposition
of any federal, state or local income taxes on the income earned from such
Mortgaged Property under section 860G(c) of the Code or otherwise, unless the
Master Servicer has agreed to indemnify and hold harmless the Trust Fund with
respect to the imposition of any such taxes.

               The decision of the Master Servicer to foreclose on a defaulted
Mortgage Loan shall be subject to a determination by the Master Servicer that
the proceeds of such foreclosure would exceed the costs and expenses of bringing
such a proceeding. The income earned from the management of any Mortgaged
Properties acquired through foreclosure or other judicial proceeding, net of
reimbursement to the Master Servicer for expenses incurred (including any
property or other taxes) in connection with such management and net of
unreimbursed Servicing Fees, Advances, Servicing Advances and any management fee
paid or to be paid with respect to the management of such Mortgaged Property,
shall be applied to the payment of principal of, and interest on, the related
defaulted Mortgage Loans (with interest accruing as though such Mortgage Loans
were still current) and all such income shall be deemed, for all purposes in
this Agreement, to be payments on account of principal and interest on the
related Mortgage Notes and shall be deposited into the Certificate Account. To
the extent the income received during a

                                      87
<PAGE>

Prepayment Period is in excess of the amount attributable to amortizing
principal and accrued interest at the related Mortgage Rate on the related
Mortgage Loan, such excess shall be considered to be a partial Principal
Prepayment for all purposes hereof.

               The Liquidation Proceeds from any liquidation of a Mortgage Loan
and any Subsequent Recoveries, net of any payment to the Master Servicer as
provided above, shall be deposited in the Certificate Account as provided in
Section 3.05 for distribution on the related Distribution Date, except that any
Excess Proceeds shall be retained by the Master Servicer as additional servicing
compensation.

               The proceeds of any Liquidated Mortgage Loan, as well as any
recovery resulting from a partial collection of Liquidation Proceeds or any
income from an REO Property, will be applied in the following order of priority:
first, to reimburse the Master Servicer for any related unreimbursed Servicing
Advances and Servicing Fees, pursuant to Section 3.08(a)(vi) or this Section
3.12; second, to reimburse the Master Servicer for any unreimbursed Advances,
pursuant to Section 3.08(a)(ii) or this Section 3.12; third, to accrued and
unpaid interest (to the extent no Advance has been made for such amount) on the
Mortgage Loan or related REO Property, at the Net Mortgage Rate to the Due Date
occurring in the month in which such amounts are required to be distributed; and
fourth, as a recovery of principal of the Mortgage Loan.

               (c) [Reserved]

               (d) The Master Servicer, in its sole discretion, shall have the
right to elect (by written notice sent to the Trustee) to purchase for its own
account from the Trust Fund any Mortgage Loan that is 150 days or more
delinquent at a price equal to the Purchase Price; provided, however, that the
Master Servicer may only exercise this right on or before the last day of the
calendar month in which such Mortgage Loan became 150 days delinquent (such
month, the "Eligible Repurchase Month"); provided further, that any such
Mortgage Loan which becomes current but thereafter becomes delinquent may be
purchased by the Master Servicer pursuant to this Section in any ensuing
Eligible Repurchase Month. The Purchase Price for any Mortgage Loan purchased
hereunder shall be deposited in the Certificate Account. Any purchase of a
Mortgage Loan pursuant to this Section 3.12(d) shall be accomplished by
remittance to the Master Servicer for deposit in the Certificate Account of the
Purchase Price. The Trustee, upon receipt of certification from the Master
Servicer of such deposit and a Request for File Release from the Master
Servicer, shall release or cause to be released to the purchaser of such
Mortgage Loan the related Mortgage File and shall execute and deliver such
instruments of transfer or assignment prepared by the purchaser of such Mortgage
Loan, in each case without recourse, as shall be necessary to vest in the
purchaser of such Mortgage Loan any Mortgage Loan released pursuant hereto and
the purchaser of such Mortgage Loan shall succeed to all the Trustee's right,
title and interest in and to such Mortgage Loan and all security and documents
related thereto. Such assignment shall be an assignment outright and not for
security. The purchaser of such Mortgage Loan shall thereupon own such Mortgage
Loan, and all security and documents, free of any further obligation to the
Trustee or the Certificateholders with respect thereto.

               Section 3.13  Co-Trustee to Cooperate; Release of Mortgage Files.

               Upon the payment in full of any Mortgage Loan, or the receipt by
the Master Servicer of a notification that payment in full will be escrowed in a
manner customary for such purposes, the Master Servicer will promptly notify the
Co-Trustee by delivering a Request for File Release. Upon receipt of such
request, the Co-Trustee shall promptly release the related Mortgage File to the
Master Servicer, and the Co-Trustee shall at the Master Servicer's direction
execute and deliver to the Master Servicer the request for reconveyance, deed of
reconveyance or release or satisfaction of mortgage or such instrument releasing
the lien of the Mortgage in each case provided by the Master Servicer, together
with the Mortgage Note with written evidence of cancellation thereon. The Master
Servicer is authorized to cause the removal from the registration on the MERS(R)
System of such Mortgage and to execute and deliver, on behalf of the Trust Fund
and the Certificateholders or any of them, any and all instruments of
satisfaction or cancellation or of partial or full release. No expenses incurred
in connection with any instrument of satisfaction or deed of reconveyance shall
be chargeable to the Certificate Account, the Distribution Account, the
Carryover Reserve Fund or the related subservicing account. From time to time
and as shall be appropriate for the servicing or foreclosure of any Mortgage
Loan, including for such purpose, collection under any policy of flood insurance
any fidelity bond or errors or omissions policy, or for the purposes of
effecting a partial release of any Mortgaged Property from the lien of the
Mortgage or the making of any corrections to the Mortgage Note or the Mortgage
or any of the other documents included in the Mortgage File, the Co-Trustee
shall, upon delivery to the Co-Trustee of a Request for Document Release or a
Request for File Release, as applicable, release the documents specified in such
request or the Mortgage File, as the case may be, to the Master Servicer.
Subject to the further limitations set forth below, the Master Servicer shall
cause the Mortgage File or documents so released to be returned to the
Co-Trustee when the need therefor by the Master Servicer no longer exists,
unless the Mortgage Loan is liquidated and the proceeds thereof are deposited in
the Certificate Account, in which case the Master Servicer shall deliver to the
Co-Trustee a Request for File Release for any remaining documents in the
Mortgage File not in the possession of the Master Servicer.

               If the Master Servicer at any time seeks to initiate a
foreclosure proceeding in respect of any Mortgaged Property as authorized by
this Agreement, the Master Servicer shall deliver or cause to be delivered to
the Trustee, for signature, as appropriate, any court pleadings, requests for
trustee's sale or other documents necessary to effectuate such foreclosure or
any legal action brought to obtain judgment against the Mortgagor on the
Mortgage Note or the Mortgage or to obtain a deficiency judgment or to enforce
any other remedies or rights provided by the Mortgage Note or the Mortgage or
otherwise available at law or in equity. Notwithstanding the foregoing, the
Master Servicer shall cause possession of any Mortgage File or of the documents
therein that shall have been released by the Co-Trustee to be returned to the
Co-Trustee within 21 calendar days after possession thereof shall have been
released by the Co-Trustee unless (i) the Mortgage Loan has been liquidated and
the Liquidation Proceeds relating to the Mortgage Loan have been deposited in
the Certificate Account, and the Master Servicer shall have delivered to the
Co-Trustee a Request for File Release or (ii) the Mortgage File or document
shall have been delivered to an attorney or to a public trustee or other public
official as required by law for purposes of initiating or pursuing legal action
or other proceedings for the foreclosure of the Mortgaged Property and the
Master Servicer shall have delivered to the Trustee an Officer's Certificate of
a Servicing Officer certifying as to the name and address of

                                      89
<PAGE>

the Person to which the Mortgage File or the documents therein were delivered
and the purpose or purposes of such delivery.

               Section 3.14  Documents, Records and Funds in Possession of
                             Master Servicer to be Held for the Trustee.

               Notwithstanding any other provisions of this Agreement, the
Master Servicer shall transmit to the Co-Trustee as required by this Agreement
all documents and instruments in respect of a Mortgage Loan coming into the
possession of the Master Servicer from time to time and shall account fully to
the Trustee for any funds received by the Master Servicer or that otherwise are
collected by the Master Servicer as Liquidation Proceeds, Insurance Proceeds or
Subsequent Recoveries in respect of any Mortgage Loan. All Mortgage Files and
funds collected or held by, or under the control of, the Master Servicer in
respect of any Mortgage Loans, whether from the collection of principal and
interest payments or from Liquidation Proceeds or Subsequent Recoveries,
including but not limited to, any funds on deposit in the Certificate Account,
shall be held by the Master Servicer for and on behalf of the Trust Fund and
shall be and remain the sole and exclusive property of the Trust Fund, subject
to the applicable provisions of this Agreement. The Master Servicer also agrees
that it shall not create, incur or subject any Mortgage File or any funds that
are deposited in the Certificate Account, the Distribution Account, the
Carryover Reserve Fund or in any Escrow Account (as defined in Section 3.06), or
any funds that otherwise are or may become due or payable to the Trustee for the
benefit of the Certificateholders, to any claim, lien, security interest,
judgment, levy, writ of attachment or other encumbrance, or assert by legal
action or otherwise any claim or right of set off against any Mortgage File or
any funds collected on, or in connection with, a Mortgage Loan, except, however,
that the Master Servicer shall be entitled to set off against and deduct from
any such funds any amounts that are properly due and payable to the Master
Servicer under this Agreement.

               Section 3.15  Servicing Compensation.

               As compensation for its activities hereunder, the Master Servicer
shall be entitled to retain or withdraw from the Certificate Account out of each
payment of interest on a Mortgage Loan included in the Trust Fund an amount
equal to interest at the applicable Servicing Fee Rate on the Stated Principal
Balance of the related Mortgage Loan for the period covered by such interest
payment.

               Additional servicing compensation in the form of any Excess
Proceeds, assumption fees, late payment charges, Prepayment Interest Excess, and
all income and gain net of any losses realized from Permitted Investments shall
be retained by the Master Servicer to the extent not required to be deposited in
the Certificate Account pursuant to Section 3.05 or 3.12(b) hereof. The Master
Servicer shall be required to pay all expenses incurred by it in connection with
its servicing activities hereunder (including payment of any premiums for hazard
insurance, as required by Section 3.10 hereof and maintenance of the other forms
of insurance coverage required by Section 3.10 hereof) and shall not be entitled
to reimbursement therefor except as specifically provided in Sections 3.08 and
3.12 hereof.

               Section 3.16  Access to Certain Documentation.

               The Master Servicer shall provide to the OTS and the FDIC and to
comparable regulatory authorities supervising Holders of the Certificates and
Certificate Owners and the examiners and supervisory agents of the OTS, the FDIC

provide access as provided in this Section as a result of such obligation shall
not constitute a breach of this Section.

               Section 3.19  The Corridor Contract.

               CHL shall assign all of its right, title and interest in and to
the interest rate corridor transactions evidenced by the Corridor Contract to,
and shall cause all of its obligations in respect of such transactions to be
assumed by, the Trustee on behalf of the Trust Fund, on the terms and conditions
set forth in the Corridor Contract Assignment Agreement. The Corridor Contract
will be an asset of the Trust Fund but will not be an asset of any REMIC. The
Master Servicer, on behalf of the Trustee, shall deposit any amounts received
from time to time with respect to the Corridor Contract into the Carryover
Reserve Fund.

               The Master Servicer, on behalf of the Trustee, shall prepare and
deliver any notices required to be delivered under the Corridor Contract.

               The Master Servicer, on behalf of the Trustee, shall act as
calculation agent and/or shall terminate the Corridor Contract, in each case
upon the occurrence of certain events of default or termination events to the
extent specified thereunder. Upon any such termination, the Corridor Contract
Counterparty will be obligated to pay the Trustee or the Master Servicer for the
benefit of the Trust Fund an amount in respect of such termination. Any amounts
received by the Trustee or the Master Servicer for the benefit of the Trust
Fund, as the case may be, in respect of such termination shall be deposited and
held in the Carryover Reserve Fund to pay Net Rate Carryover for the applicable
Classes of Certificates as provided in Section 4.04(e) on the Distribution Dates
following such termination to and including the Corridor Contract Termination
Date, but shall not be available for distribution to the Class C Certificates
pursuant to Section 4.08(c) until the Corridor Contract Termination Date. On the
Corridor Contract Termination Date, after all other distributions on such date,
if any amounts in respect of early termination of the Corridor Contract remain
in the Carryover Reserve Fund, such amounts shall be distributed by the Trustee
to the Class C Certificates.

               Section 3.20  Prepayment Charges.

               (a) Notwithstanding anything in this Agreement to the contrary,
in the event of a Principal Prepayment in full or in part of a Mortgage Loan,
the Master Servicer may not waive any Prepayment Charge or portion thereof
required by the terms of the related Mortgage Note unless (i) such Mortgage Loan
is in default or the Master Servicer believes that such default is imminent and
the Master Servicer determines that such waiver would maximize recovery of
Liquidation Proceeds for such Mortgage Loan, taking into account the value of
such Prepayment Charge, or (ii) (A) the enforceability thereof is limited (1) by
bankruptcy, insolvency, moratorium, receivership, or other similar law relating
to creditors' rights generally or (2) due to acceleration in connection with a
foreclosure or other involuntary payment, or (B) the enforceability is otherwise
limited or prohibited by applicable law. In the event of a Principal Prepayment
in full or in part with respect to any Mortgage Loan, the Master Servicer shall
deliver to the Trustee an Officer's Certificate substantially in the form of
Exhibit T no later than the third Business Day following the immediately
succeeding Determination Date with a copy to the Class P Certificateholders. If
the Master Servicer has waived or does not collect all or a portion of a
Prepayment Charge relating to a Principal Prepayment in full or in part due to
any action or omission of the Master Servicer, other than as provided above, the
Master Servicer shall deliver to the Trustee, together with the Principal
Prepayment in full or in part, the amount

                                      92
<PAGE>

of such Prepayment Charge (or such portion thereof as had been waived) for
deposit into the Certificate Account (not later than 1:00 p.m. Pacific time on
the immediately succeeding Master Servicer Advance Date, in the case of such
Prepayment Charge) for distribution in accordance with the terms of this
Agreement.

               (b) Upon discovery by the Master Servicer or a Responsible
Officer of the Trustee of a breach of the foregoing subsection (a), the party
discovering the breach shall give prompt written notice to the other parties.

               (c) CHL represents and warrants to the Depositor and the Trustee,
as of the Closing Date and each Subsequent Transfer Date, that the information
in the Prepayment Charge Schedule (including the attached prepayment charge
summary) is complete and accurate in all material respects at the dates as of
which the information is furnished and each Prepayment Charge is permissible and
enforceable in accordance with its terms under applicable state law, except as
the enforceability thereof is limited due to acceleration in connection with a
foreclosure or other involuntary payment.

               (d) Upon discovery by the Master Servicer or a Responsible
Officer of the Trustee of a breach of the foregoing clause (c) that materially
and adversely affects right of the Holders of the Class P Certificates to any
Prepayment Charge, the party discovering the breach shall give prompt written
notice to the other parties. Within 60 days of the earlier of discovery by the
Master Servicer or receipt of notice by the Master Servicer of breach, the
Master Servicer shall cure the breach in all material respects or shall pay into
the Certificate Account the amount of the Prepayment Charge that would otherwise
be due from the Mortgagor, less any amount representing such Prepayment Charge
previously collected and paid by the Master Servicer into the Certificate
Account.

                                  ARTICLE IV.
               DISTRIBUTIONS AND ADVANCES BY THE MASTER SERVICER

               Section 4.01  Advances; Remittance Reports.

               (a) Within two Business Days after each Determination Date, the
Master Servicer shall deliver to the Trustee by facsimile or electronic mail (or
by such other means as the Master Servicer and the Trustee, as the case may be,
may agree from time to time) a Remittance Report with respect to the related
Distribution Date. The Trustee shall not be responsible to recompute,
recalculate or verify any information provided to it by the Master Servicer.

               (b) Subject to the conditions of this Article IV, the Master
Servicer, as required below, shall make an Advance and deposit such Advance in
the Certificate Account. Each such Advance shall be remitted to the Certificate
Account no later than 1:00 p.m. Pacific time on the Master Servicer Advance Date
in immediately available funds. The Trustee will provide notice to the Master
Servicer by facsimile by the close of business on any Master Servicer Advance
Date in the event that the amount remitted by the Master Servicer to the Trustee
on the Distribution Account Deposit Date is less than the Advances required to
be made by the Master Servicer for such Distribution Date. The Master Servicer
shall be obligated to

                                      93
<PAGE>

make any such Advance only to the extent that such advance would not be a
Nonrecoverable Advance. If the Master Servicer shall have determined that it
has made a Nonrecoverable Advance or that a proposed Advance or a lesser
portion of such Advance would constitute a Nonrecoverable Advance, the Master
Servicer shall deliver (i) to the Trustee for the benefit of the
Certificateholders funds constituting the remaining portion of such Advance,
if applicable, and (ii) to the Depositor, each Rating Agency and the Trustee
an Officer's Certificate setting forth the basis for such determination.

               (c) In lieu of making all or a portion of such Advance from its
own funds, the Master Servicer may (i) cause to be made an appropriate entry in
its records relating to the Certificate Account that any Amount Held for Future
Distributions has been used by the Master Servicer in discharge of its
obligation to make any such Advance and (ii) transfer such funds from the
Certificate Account to the Distribution Account. Any funds so applied and
transferred shall be replaced by the Master Servicer by deposit in the
Certificate Account no later than the close of business on the Business Day
immediately preceding the Distribution Date on which such funds are required to
be distributed pursuant to this Agreement. The Master Servicer shall be entitled
to be reimbursed from the Certificate Account for all Advances of its own funds
made pursuant to this Section as provided in Section 3.08. The obligation to
make Advances with respect to any Mortgage Loan shall continue until such
Mortgage Loan is paid in full or the related Mortgaged Property or related REO
Property has been liquidated or until the purchase or repurchase thereof (or
substitution therefor) from the Trustee pursuant to any applicable provision of
this Agreement, except as otherwise provided in this Section 4.01.

               (d) If the Master Servicer determines that it will be unable to
comply with its obligation to make the Advances as and when described in
paragraphs (b) and (c) immediately above, it shall use its best efforts to give
written notice thereof to the Trustee (each such notice a "Trustee Advance
Notice"; and such notice may be given by facsimile), not later than 3:00 p.m.,
New York time, on the Business Day immediately preceding the related Master
Servicer Advance Date, specifying the amount that it will be unable to deposit
(each such amount an "Advance Deficiency") and certifying that such Advance
Deficiency constitutes an Advance hereunder and is not a Nonrecoverable Advance.
If the Trustee receives a Trustee Advance Notice on or before 3:30 p.m., (New
York time) on a Master Servicer Advance Date, the Trustee shall, not later than
3:00 p.m., (New York time), on the related Distribution Date, deposit in the
Distribution Account an amount equal to the Advance Deficiency identified in
such Trustee Advance Notice unless it is prohibited from so doing by applicable
law. Notwithstanding the foregoing, the Trustee shall not be required to make
such deposit if the Trustee shall have received written notification from the
Master Servicer that the Master Servicer has deposited or caused to be deposited
in the Certificate Account an amount equal to such Advance Deficiency. All
Advances made by the Trustee pursuant to this Section 4.01(d) shall accrue
interest on behalf of the Trustee at the Trustee Advance Rate from and including
the date such Advances are made to but excluding the date of repayment, with
such interest being an obligation of the Master Servicer and not the Trust Fund.
The Master Servicer shall reimburse the Trustee for the amount of any Advance
made by the Trustee pursuant to this Section 4.01(d) together with accrued
interest, not later than 6:00 p.m. (New York time) on the Business Day following
the related Distribution Date. In the event that the Master Servicer does not
reimburse the Trustee in accordance with the requirements of the preceding
sentence, the Trustee shall immediately (i) terminate all of the rights and
obligations of the Master Servicer under this Agreement in

                                      94
<PAGE>

accordance with Section 7.01 and (ii) subject to the limitations set forth in
Section 3.04, assume all of the rights and obligations of the Master Servicer
hereunder.

               (e) On or before 5:00 p.m. Pacific time on the fifth Business Day
following each Determination Date (but in no event later than 5:00 p.m. Pacific
time on the third Business Day before the related Distribution Date) the Master
Servicer shall deliver to the Trustee a report (in form and substance reasonably
satisfactory to the Trustee) that indicates (i) the Mortgage Loans with respect
to which the Master Servicer has determined that the related Scheduled Payments
should be advanced and (ii) the amount of the related Scheduled Payments. The
Master Servicer shall deliver to the Trustee on the related Master Servicer
Advance Date an Officer's Certificate of a Servicing Officer indicating the
amount of any proposed Advance determined by the Master Servicer to be a
Nonrecoverable Advance.

               Section 4.02  Reduction of Servicing Compensation in Connection
                             with Prepayment Interest Shortfalls.

               In the event that any Mortgage Loan is the subject of a
Prepayment Interest Shortfall, the Master Servicer shall remit any related
Compensating Interest as part of the related Interest Remittance Amount as
provided in this Agreement. The Master Servicer shall not be entitled to any
recovery or reimbursement for Compensating Interest from the Depositor, the
Trustee, either Seller, the Trust Fund or the Certificateholders.

        Principal Balance thereof is reduced to zero;

                      (2) to the Class M-2 Certificates, but not by more than
        the amount of the Unpaid Realized Loss Amount of the Class M-2
        Certificates;

                      (3) to the Class M-3 Certificates, but not by more than
        the amount of the Unpaid Realized Loss Amount of the Class M-3
        Certificates;

                      (4) to the Class M-4 Certificates, but not by more than

        Certificates; and

                      (7) to the Class B Certificates, but not by more than the

Certificate Principal Balance of not less than $1,000,000 or evidencing a

address of such Holder appearing in the Certificate Register. Notwithstanding
the foregoing, but subject to Section 9.02 hereof respecting the final
distribution, distributions with respect to Certificates registered in the name

received under the Corridor Contract may be invested in Permitted Investments at
the direction of the Majority Holder of the Class C Certificates (voting as a
single Class), which Permitted Investments shall mature not later than the
Business Day immediately preceding the first Distribution Date that follows the
date of such investment (except that if such Permitted Investment is an
obligation of the institution that maintains the Carryover Reserve Fund, then
such Permitted Investment shall mature not later than such Distribution Date)

hereto executed by the Trustee by manual signature, and such certificate of
authentication upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly authenticated and delivered
hereunder. All Certificates shall be dated the date of their

Class and of like aggregate Percentage Interest.

               At the option of a Certificateholder, Certificates may be
exchanged for other Certificates of the same Class in authorized denominations
and evidencing the same aggregate Percentage Interest upon surrender of the
Certificates to be exchanged at the office or agency of the Trustee. Whenever
any Certificates are so surrendered for exchange, the Trustee shall execute,
authenticate, and deliver the Certificates that the Certificateholder making the
exchange is entitled to receive. Every Certificate presented or surrendered for
registration of Transfer or exchange shall be accompanied by a written
instrument of Transfer in form satisfactory to the Trustee duly executed by the
Holder thereof or his attorney duly authorized in writing.

               No service charge to the Certificateholders shall be made for any
registration of Transfer or exchange of Certificates, but payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any Transfer or exchange of Certificates may be required.

               All Certificates surrendered for registration of Transfer or
exchange shall be canceled and subsequently destroyed by the Trustee in
accordance with the Trustee's customary procedures.

               (b) No Transfer of a Private Certificate shall be made unless
such Transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under the Securities Act and such state securities
laws. In the event that a transfer is to be made in reliance upon an exemption
from the Securities Act and such state securities laws, in order to assure
compliance with the Securities Act and such state securities laws, the
Certificateholder desiring to effect such Transfer and such Certificateholder's
prospective transferee shall (except in connection with any transfer of a
Private Certificate to an affiliate of the Depositor (either directly or through
a nominee) on or about the Closing Date) each certify to the Trustee in writing
the facts surrounding the Transfer in substantially the forms set forth in
Exhibit J-2 and, in the case of a Class A-R Certificate, Exhibit J-1 (each, a
"Transferor Certificate") and (i) deliver a letter in substantially the form of
either Exhibit K (the "Investment Letter") or Exhibit L (the "Rule 144A

                                     106
<PAGE>

Letter") or (ii) there shall be delivered to the Trustee at the expense of the
Certificateholder desiring to effect such transfer an Opinion of Counsel that
such Transfer may be made pursuant to an exemption from the Securities Act;
provided, however, that in the case of the delivery of an Investment Letter in
connection with the transfer of any Class C or Class P Certificate to a
transferee that is formed with the purpose of issuing notes backed by such
Class C or Class P Certificate, as the case may be, clause (b) and (c) of the
form of Investment Letter shall not be applicable and shall be deleted by such
transferee. The Depositor shall provide to any Holder of a Private Certificate
and any prospective transferee designated by any such Holder, information
regarding the related Certificates and the Mortgage Loans and such other
information as shall be necessary to satisfy the condition to eligibility set
forth in Rule 144A(d)(4) for transfer of any such Certificate without
registration thereof under the Securities Act pursuant to the registration
exemption provided by Rule 144A. The Trustee, the Co-Trustee and the Master
Servicer shall cooperate with the Depositor in providing the Rule 144A
information referenced in the preceding sentence, including providing to the
Depositor such information regarding the Certificates, the Mortgage Loans and
other matters regarding the Trust Fund as the Depositor shall reasonably
request to meet its obligation under the preceding sentence. Each Holder of a
Private Certificate desiring to effect such Transfer shall, and does hereby
agree to, indemnify the Trustee, the Co-Trustee, the Depositor, the Trust
Fund, each Seller, the Master Servicer and the NIM Insurer against any
liability that may result if the Transfer is not so exempt or is not made in
accordance with such federal and state laws.

               No Transfer of an ERISA-Restricted Certificate (other than a
transfer of an ERISA-Restricted Certificate to an affiliate of the Depositor
(either directly or through a nominee) on or about the Closing Date) shall be
made unless the Trustee shall have received either (i) a representation from the
transferee of such Certificate acceptable to and in form and substance
satisfactory to the Trustee (in the event such Certificate is a Private
Certificate, such requirement is satisfied only by the Trustee's receipt of a
representation letter from the transferee substantially in the form of Exhibit K
or Exhibit L, or in the event such Certificate is a Residual Certificate, such
requirement is satisfied only by the Trustee's receipt of a representation
letter from the transferee substantially in the form of Exhibit I), to the
effect that (x) such transferee is not an employee benefit plan or arrangement
subject to Section 406 of ERISA or a plan or arrangement subject to Section 4975
of the Code, or a Person acting on behalf of any such plan or arrangement or
using the assets of any such plan or arrangement, or (y) in the case of an
ERISA-Restricted Certificate that has been the subject of an ERISA-Qualifying
Underwriting, a representation that the transferee is an insurance company which
is purchasing such Certificate with funds contained in an "insurance company
general account" (as such term is defined in section V(e) of Prohibited
Transaction Class Exemption 95-60 ("PTCE 95-60")) and that the purchase and
holding of such Certificate satisfy the requirements for exemptive relief under
Sections I and III of PTCE 95-60 or (ii) in the case of any ERISA-Restricted
Certificate presented for registration in the name of an employee benefit plan
or arrangement subject to ERISA, or a plan or arrangement subject to Section
4975 of the Code (or comparable provisions of any subsequent enactments), or a
trustee of any such plan or arrangement or any other person acting on behalf of
any such plan or arrangement, an Opinion of Counsel satisfactory to the Trustee,
addressed to the Trustee and the Master Servicer, to the effect that the
purchase or holding of such ERISA-Restricted Certificate will not result in a
non-exempt prohibited transaction under ERISA or the Code and will not subject
the Trustee or the Master Servicer to any obligation in addition to those
expressly undertaken in this Agreement, which Opinion of

                                     107
<PAGE>

Counsel shall not be an expense of the Trustee, the Master Servicer, or the
Trust Fund. For purposes of the preceding sentence, one of such
representations, as appropriate, shall be deemed to have been made to the
Trustee by the transferee's acceptance of an ERISA-Restricted Certificate (or
the acceptance by a Certificate Owner of the beneficial interest in any such
Class of ERISA-Restricted Certificates) unless the Trustee shall have received
from the transferee an Opinion of Counsel as described in clause (ii) or a
representation letter acceptable in form and substance to the Trustee.
Notwithstanding anything else to the contrary herein, any purported transfer
of an ERISA-Restricted Certificate to or on behalf of an employee benefit plan
subject to Section 406 of ERISA or a plan subject to Section 4975 of the Code
without the delivery to the Trustee of an Opinion of Counsel satisfactory to
the Trustee meeting the requirements of clause (i) of the first sentence of
this paragraph as described above shall be void and of no effect. The Trustee
shall be under no liability to any Person for any registration of transfer of
any ERISA-Restricted Certificate that is in fact not permitted by this Section
5.02(b) or for making any payments due on such Certificate to the Holder
thereof or taking any other action with respect to such Holder under the
provisions of this Agreement so long as the Trustee, with respect to the
transfer of such Classes of Certificates, required delivery of such
certificates and other documentation or evidence as are expressly required by
the terms of this Agreement and examined such certificates and other
documentation or evidence to determine compliance as to form with the express
requirements hereof. The Trustee shall be entitled, but not obligated, to
recover from any Holder of any ERISA-Restricted Certificate that was in fact
an employee benefit plan or arrangement subject to Section 406 of ERISA or a
plan or arrangement subject to Section 4975 of the Code or a Person acting on
behalf of any such plan or arrangement at the time it became a Holder or, at
such subsequent time as it became such a plan or arrangement or Person acting
on behalf of such a plan or arrangement, all payments made on such
ERISA-Restricted Certificate at and after either such time. Any such payments
so recovered by the Trustee shall be paid and delivered by the Trustee to the
last preceding Holder of such Certificate that is not such a plan or
arrangement or Person acting on behalf of a plan or arrangement.

               (c)    Each Person who has or who acquires any Ownership
Interest in a Class A-R Certificate shall be deemed by the acceptance or
acquisition of such Ownership Interest to have agreed to be bound by the
following provisions, and the rights of each Person acquiring any Ownership
Interest in a Class A-R Certificate are expressly subject to the following
provisions:

                      (1) Each Person holding or acquiring any Ownership
        Interest in a Class A-R Certificate shall be a Permitted Transferee and
        shall promptly notify the Trustee of any change or impending change in
        its status as a Permitted Transferee.

                      (2) Except in connection with any registration in the name
        of, or transfer of a Class A-R Certificate to, an affiliate of the
        Depositor (either directly or through a nominee) on or about the Closing
        Date, no Ownership Interest in a Class A-R Certificate may be registered
        or transferred, and the Trustee shall not register the Transfer of any
        Class A-R Certificate, unless the Trustee shall have been furnished with
        an affidavit (a "Transfer Affidavit") of the initial owner or the
        proposed transferee in the form attached hereto as Exhibit I.

                      (3) Each Person holding or acquiring any Ownership
        Interest in a Class A-R Certificate shall agree (A) to obtain a Transfer
        Affidavit from any other Person

                                     108
<PAGE>

        to whom such Person attempts to Transfer its Ownership Interest in a
        Class A-R Certificate, (B) to obtain a Transfer Affidavit from any
        Person for whom such Person is acting as nominee, trustee or agent in
        connection with any Transfer of a Class A-R Certificate and (C) not to
        Transfer its Ownership Interest in a Class A-R Certificate, or to
        cause the Transfer of an Ownership Interest in a Class A-R Certificate
        to any other Person, if it has actual knowledge that such Person is
        not a Permitted Transferee or that such Transfer Affidavit is false.

                      (4) Any attempted or purported Transfer of any Ownership
        Interest in a Class A-R Certificate in violation of the provisions of
        this Section 5.02(c) shall be absolutely null and void and shall vest no
        rights in the purported Transferee. If any purported transferee shall
        become a Holder of a Class A-R Certificate in violation of the
        provisions of this Section 5.02(c), then the last preceding Permitted
        Transferee shall be restored to all rights as Holder thereof retroactive
        to the date of registration of Transfer of such Class A-R Certificate.
        The Trustee shall be under no liability to any Person for any
        registration of Transfer of a Class A-R Certificate that is in fact not
        permitted by Section 5.02(b) and this Section 5.02(c) or for making any
        payments due on such Certificate to the Holder thereof or taking any
        other action with respect to such Holder under the provisions of this
        Agreement so long as the Transfer was registered after receipt of the
        related Transfer Affidavit and Transferor Certificate. The Trustee shall
        be entitled but not obligated to recover from any Holder of a Class A-R
        Certificate that was in fact not a Permitted Transferee at the time it
        became a Holder or, at such subsequent time as it became other than a
        Permitted Transferee, all payments made on such Class A-R Certificate at
        and after either such time. Any such payments so recovered by the
        Trustee shall be paid and delivered by the Trustee to the last preceding
        Permitted Transferee of such Certificate.

                      (5) The Master Servicer shall use its best efforts to make
        available, upon receipt of written request from the Trustee, all
        information necessary to compute any tax imposed under section 860E(e)
        of the Code as a result of a Transfer of an Ownership Interest in a
        Class A-R Certificate to any Holder who is not a Permitted Transferee.

               The restrictions on Transfers of a Class A-R Certificate set
forth in this section 5.02(c) shall cease to apply (and the applicable portions
of the legend on a Class A-R Certificate may be deleted) with respect to
Transfers occurring after delivery to the Trustee of an Opinion of Counsel,
which Opinion of Counsel shall not be an expense of the Trustee, either Seller
or the Master Servicer to the effect that the elimination of such restrictions
will not cause any REMIC formed hereunder to fail to qualify as a REMIC at any
time that the Certificates are outstanding or result in the imposition of any
tax on the Trust Fund, a Certificateholder or another Person. Each Person
holding or acquiring any Ownership Interest in a Class A-R Certificate, by
acceptance of its Ownership Interest, shall be deemed to consent to any
amendment of this Agreement that, based on an Opinion of Counsel furnished to
the Trustee, is reasonably necessary (a) to ensure that the record ownership of,
or any beneficial interest in, a Class A-R Certificate is not transferred,
directly or indirectly, to a Person that is not a Permitted Transferee and (b)
to provide for a means to compel the Transfer of a Class A-R Certificate that is
held by a Person that is not a Permitted Transferee to a Holder that is a
Permitted Transferee.

                                     109
<PAGE>

               (d) The preparation and delivery of all affidavits,
certifications and opinions referred to above in this section 5.02 shall not be
an expense of the Trust Fund, the Trustee, the Depositor, either Seller or the
Master Servicer.

               Section 5.03  Mutilated, Destroyed, Lost or Stolen Certificates.

               If (a) any mutilated Certificate is surrendered to the Trustee,
or the Trustee receives evidence to its satisfaction of the destruction, loss or
theft of any Certificate and of the ownership thereof and (b) there is delivered
to the Master Servicer and the Trustee such security or indemnity as may be
required by them to save each of them harmless, then, in the absence of notice
to the Trustee that such Certificate has been acquired by a bona fide purchaser,
the Trustee shall execute, authenticate and deliver, in exchange for or in lieu
of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate
of like Class, tenor and Percentage Interest. In connection with the issuance of
any new Certificate under this Section 5.03, the Trustee may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto and any other expenses (including the fees and
expenses of the Trustee) connected therewith. Any replacement Certificate issued
pursuant to this Section 5.03 shall constitute complete and indefeasible
evidence of ownership in the Trust Fund, as if originally issued, whether or not
the lost, stolen or destroyed Certificate shall be found at any time. All
Certificates surrendered to the Trustee under the terms of this Section 5.03
shall be canceled and destroyed by the Trustee in accordance with its standard
procedures without liability on its part.

               Section 5.04  Persons Deemed Owners.

               The Master Servicer, the Trustee and any agent of the Master
Servicer or the Trustee may treat the person in whose name any Certificate is
registered as the owner of such Certificate for the purpose of receiving
distributions as provided in this Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Trustee or the NIM Insurer or
any agent of the Master Servicer, the Trustee or the NIM Insurer shall be
affected by any notice to the contrary.

               Section 5.05  Access to List of Certificateholders' Names
                             and Addresses.

               If three or more Certificateholders or Certificate Owners (a)
request such information in writing from the Trustee, (b) state that such
Certificateholders or Certificate Owners desire to communicate with other
Certificateholders or Certificate Owners with respect to their rights under this
Agreement or under the Certificates and (c) provide a copy of the communication
that such Certificateholders or Certificate Owners propose to transmit or if the
Depositor or Master Servicer shall request such information in writing from the
Trustee, then the Trustee shall, within ten Business Days after the receipt of
such request, provide the Depositor, the Master Servicer or such
Certificateholders or Certificate Owners at such recipients' expense the most
recent list of the Certificateholders of the Trust Fund held by the Trustee, if
any. The Depositor and every Certificateholder or Certificate Owner, by
receiving and holding a Certificate, agree that the Trustee shall not be held
accountable by reason of the disclosure of any such information as to the list
of the Certificateholders hereunder, regardless of the source from which such
information was derived.

               Section 5.06  Book-Entry Certificates.

               The Book-Entry Certificates, upon original issuance, shall be
issued in the form of one typewritten Certificate (or more than one, if required
by the Depository) for each Class of such Certificates, to be delivered to the
Depository by or on behalf of the Depositor. Such Certificates shall initially
be registered on the Certificate Register in the name of the Depository or its
nominee, and no Certificate Owner of such Certificates will receive a definitive
certificate representing such Certificate Owner's interest in such Certificates,
except as provided in Section 5.08. Unless and until definitive, fully
registered Certificates ("Definitive Certificates") have been issued to the
Certificate Owners of such Certificates pursuant to Section 5.08:

               (a) the provisions of this Section shall be in full force and
effect;

               (b) the Depositor, the Sellers, the Master Servicer and the
Trustee may deal with the Depository and the Depository Participants for all
purposes (including the making of distributions) as the authorized
representative of the respective Certificate Owners of such Certificates;

               (c) registration of the Book-Entry Certificates may not be
transferred by the Trustee except to another Depository;

               (d) the rights of the respective Certificate Owners of such
Certificates shall be exercised only through the Depository and the Depository
Participants and shall be limited to those established by law and agreements
between the Owners of such Certificates and the Depository and/or the Depository
Participants. Pursuant to the Depository Agreement, unless and until Definitive
Certificates are issued pursuant to Section 5.08, the Depository will make
book-entry transfers among the Depository Participants and receive and transmit
distributions of principal and interest on the related Certificates to such
Depository Participants;

               (e) the Depository may collect its usual and customary fees,
charges and expenses from its Depository Participants;

               (f) the Trustee may rely and shall be fully protected in relying
upon information furnished by the Depository with respect to its Depository
Participants; and

               (g) to the extent the provisions of this Section conflict with
any other provisions of this Agreement, the provisions of this Section shall
control.

               For purposes of any provision of this Agreement requiring or
permitting actions with the consent of, or at the direction of,
Certificateholders evidencing a specified percentage of the aggregate unpaid
principal amount of any Class of Certificates, such direction or consent may be
given by Certificate Owners (acting through the Depository and the Depository
Participants) owning Book-Entry Certificates evidencing the requisite percentage
of principal amount of such Class of Certificates.

               Section 5.07  Notices to Depository.

               Whenever any notice or other communication is required to be
given to Certificateholders of the Class with respect to which Book-Entry
Certificates have been issued, unless and until Definitive Certificates shall
have been issued to the related Certificate Owners, the Trustee shall give all
such notices and communications to the Depository.

               Section 5.08  Definitive Certificates.

               If, after Book-Entry Certificates have been issued with respect
to any Certificates, (a) the Depositor advises the Trustee that the Depository
is no longer willing or able to discharge properly its responsibilities under
the Depository Agreement with respect to such Certificates and the Trustee or
the Depositor is unable to locate a qualified successor or (b) after the
occurrence and continuation of an Event of Default, Certificate Owners of such
Book-Entry Certificates having not less than 51% of the Voting Rights evidenced
by any Class of Book-Entry Certificates advise the Trustee and the Depository in
writing through the Depository Participants that the continuation of a
book-entry system with respect to Certificates of such Class through the
Depository (or its successor) is no longer in the best interests of the
Certificate Owners of such Class, then the Trustee shall notify all Certificate
Owners of such Certificates, through the Depository, of the occurrence of any
such event and of the availability of Definitive Certificates to Certificate
Owners of such Class requesting the same. The Depositor shall provide the
Trustee with an adequate inventory of Certificates to facilitate the issuance
and transfer of Definitive Certificates. Upon surrender to the Trustee of any
such Certificates by the Depository, accompanied by registration instructions
from the Depository for registration, the Trustee shall authenticate and deliver
such Definitive Certificates. Neither the Depositor nor the Trustee shall be
liable for any delay in delivery of such instructions and each may conclusively
rely on, and shall be protected in relying on, such instructions. Upon the
issuance of such Definitive Certificates, all references herein to obligations
imposed upon or to be performed by the Depository shall be deemed to be imposed
upon and performed by the Trustee, to the extent applicable with respect to such
Definitive Certificates and the Trustee shall recognize the Holders of such
Definitive Certificates as Certificateholders hereunder.

               Section 5.09  Maintenance of Office or Agency.

               The Trustee will maintain or cause to be maintained at its
expense an office or offices or agency or agencies in New York City where
Certificates may be surrendered for registration of transfer or exchange. The
Trustee initially designates its offices at 101 Barclay Street, New York, New
York 10286, Attention: Corporate Trust MBS Administration, as offices for such
purposes. The Trustee will give prompt written notice to the Certificateholders
of any change in such location of any such office or agency.

                                  ARTICLE VI.
              THE DEPOSITOR, THE MASTER SERVICER AND THE SELLERS

               Section 6.01  Respective Liabilities of the Depositor, the
                             Master Servicer and the Sellers.

               The Depositor, the Master Servicer and each Seller shall each be
liable in accordance herewith only to the extent of the obligations specifically
and respectively imposed upon and undertaken by them herein.

               Section 6.02  Merger or Consolidation of the Depositor, the
                             Master Servicer or the Sellers.

               The Depositor will keep in full effect its existence, rights and
franchises as a corporation under the laws of the United States or under the
laws of one of the states thereof and will each obtain and preserve its
qualification to do business as a foreign corporation in each jurisdiction in
which such qualification is or shall be necessary to protect the validity and
enforceability of this Agreement, or any of the Mortgage Loans and to perform
its duties under this Agreement. The Master Servicer will keep in effect its
existence, rights and franchises as a limited partnership under the laws of the
United States or under the laws of one of the states thereof and will obtain and
preserve its qualification or registration to do business as a foreign
partnership in each jurisdiction in which such qualification or registration is
or shall be necessary to protect the validity and enforceability of this
Agreement or any of the Mortgage Loans and to perform its duties under this
Agreement.

               Any Person into which the Depositor, the Master Servicer or
either Seller may be merged or consolidated, or any Person resulting from any
merger or consolidation to which the Depositor, the Master Servicer or either
Seller shall be a party, or any person succeeding to the business of the
Depositor, the Master Servicer or either Seller, shall be the successor of the
Depositor, the Master Servicer or such Seller, as the case may be, hereunder,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto, anything herein to the contrary notwithstanding;
provided that the successor or surviving Person to the Master Servicer shall be
qualified to service mortgage loans on behalf of Fannie Mae and Freddie Mac.

               Section 6.03  Limitation on Liability of the Depositor, the
                             Sellers, the Master Servicer, the NIM Insurer
                             and Others.

               None of the Depositor, the Sellers, the NIM Insurer or the Master
Servicer or any of the directors, officers, employees or agents of the
Depositor, the Sellers, the NIM Insurer or the Master Servicer shall be under
any liability to the Trustee (except as provided in Section 8.05), the Trust
Fund or the Certificateholders for any action taken or for refraining from the
taking of any action in good faith pursuant to this Agreement, or for errors in
judgment; provided that this provision shall not protect the Depositor, the
Sellers, the Master Servicer or any such Person against any breach of
representations or warranties made by it herein or protect the Depositor, the
Sellers, the Master Servicer or any such Person from any liability that would
otherwise be imposed by reasons of willful misfeasance, bad faith or gross
negligence in the

                                     113
<PAGE>

performance of duties or by reason of reckless disregard of obligations and
duties hereunder. The Depositor, the Sellers, the NIM Insurer, the Master
Servicer and any director, officer, employee or agent of the Depositor, the
Sellers, the NIM Insurer or the Master Servicer may rely in good faith on any
document of any kind prima facie properly executed and submitted by any Person
respecting any matters arising hereunder. The Depositor, the Sellers, the NIM
Insurer, the Master Servicer and any director, officer, employee or agent of
the Depositor, the Sellers, the NIM Insurer or the Master Servicer shall be
indemnified by the Trust Fund and held harmless against any loss, liability or
expense incurred in connection with any audit, controversy or judicial
proceeding relating to a governmental taxing authority or any legal action
relating to this Agreement or the Certificates, other than any loss, liability
or expense related to any specific Mortgage Loan or Mortgage Loans (except as
any such loss, liability or expense shall be otherwise reimbursable pursuant
to this Agreement) and any loss, liability or expense incurred by reason of
willful misfeasance, bad faith or gross negligence in the performance of
duties hereunder or by reason of reckless disregard of obligations and duties
hereunder. None of the Depositor, the Sellers, the NIM Insurer or the Master
Servicer shall be under any obligation to appear in, prosecute or defend any
legal action that is not incidental to its respective duties hereunder and
that in its opinion may involve it in any expense or liability; provided that
any of the Depositor, the Sellers, the NIM Insurer or the Master Servicer may,
in its discretion undertake any such action that it may deem necessary or
desirable in respect of this Agreement and the rights and duties of the
parties hereto and interests of the Trustee and the Certificateholders
hereunder. In such event, the legal expenses and costs of such action and any
liability resulting therefrom shall be, expenses, costs and liabilities of the
Trust Fund, and the Depositor, the Sellers, the NIM Insurer and the Master
Servicer shall be entitled to be reimbursed therefor out of the Certificate
Account as provided by Section 3.08 hereof.

               Section 6.04  Limitation on Resignation of Master Servicer.

               The Master Servicer shall not resign from the obligations and
duties hereby imposed on it except (i) upon determination that its duties
hereunder are no longer permissible under applicable law or (ii) upon
appointment of a successor servicer that is reasonably acceptable to the Trustee
and the NIM Insurer and the written confirmation from each Rating Agency (which
confirmation shall be furnished to the Depositor, the Trustee and the NIM
Insurer) that such resignation will not cause such Rating Agency to reduce the
then current rating of the Certificates. Any such determination pursuant to
clause (i) of the preceding sentence permitting the resignation of the Master
Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to
the Trustee. No resignation of the Master Servicer shall become effective until
the Trustee shall have assumed the Master Servicer's responsibilities, duties,
liabilities (other than those liabilities arising prior to the appointment of
such successor) and obligations under this Agreement.

               Section 6.05  Errors and Omissions Insurance; Fidelity Bonds.

               The Master Servicer shall, for so long as it acts as servicer
under this Agreement, obtain and maintain in force (a) a policy or policies of
insurance covering errors and omissions in the performance of its obligations as
servicer hereunder, and (b) a fidelity bond in respect of its officers,
employees and agents. Each such policy or policies and bond shall, together,
comply with the requirements from time to time of Fannie Mae and Freddie Mac for
persons performing

                                     114

servicing for mortgage loans purchased by Fannie Mae and Freddie Mac. In the
event that any such policy or bond ceases to be in effect, the Master Servicer
shall use its reasonable best efforts to obtain a comparable replacement
policy or bond from an insurer or issuer, meeting the requirements set forth
above as of the date of such replacement.

               The Master Servicer shall provide the Trustee and the NIM Insurer
(upon such party's reasonable request) with copies of any such insurance
policies and fidelity bond. The Master Servicer shall be deemed to have complied
with this provision if an Affiliate of the Master Servicer has such errors and
omissions and fidelity bond coverage and, by the terms of such insurance policy
or fidelity bond, the coverage afforded thereunder extends to the Master
Servicer.

                    DEFAULT; TERMINATION OF MASTER SERVICER

               Section 7.01  Events of Default.

               "Event of Default," wherever used herein, means any one of the
following events:

                      (1) any failure by the Master Servicer to deposit in the
        Certificate Account or the Distribution Account or remit to the Trustee
        any payment (excluding a payment required to be made under Section 4.01
        hereof) required to be made under the terms of this Agreement, which
        failure shall continue unremedied for five calendar days and, with
        respect to a payment required to be made under Section 4.01(b) or (c)
        hereof, for one Business Day, after the date on which written notice of
        such failure shall have been given to the Master Servicer by the
        Trustee, the NIM Insurer or the Depositor, or to the Trustee, the NIM
        Insurer and the Master Servicer by the Holders of Certificates
        evidencing not less than 25% of the Voting Rights; or

                      (2) any failure by the Master Servicer to observe or
        perform in any material respect any other of the covenants or agreements
        on the part of the Master Servicer contained in this Agreement or any
        representation or warranty shall prove to be untrue, which failure or
        breach shall continue unremedied for a period of 60 days after the date
        on which written notice of such failure shall have been given to the
        Master Servicer by the Trustee, the NIM Insurer or the Depositor, or to
        the Trustee by the Holders of Certificates evidencing not less than 25%
        of the Voting Rights; provided that the sixty-day cure period shall not
        apply to the initial delivery of the Mortgage File for Delay Delivery
        Mortgage Loans nor the failure to repurchase or substitute in lieu
        thereof; or

                      (3) a decree or order of a court or agency or supervisory
        authority having jurisdiction in the premises for the appointment of a
        receiver or liquidator in any insolvency, readjustment of debt,
        marshalling of assets and liabilities or similar proceedings, or for the
        winding-up or liquidation of its affairs, shall have been entered
        against the Master Servicer and such decree or order shall have remained
        in force undischarged or unstayed for a period of 60 consecutive days;
        or

                                     115
<PAGE>

                      (4) the Master Servicer shall consent to the appointment
        of a receiver or liquidator in any insolvency, readjustment of debt,
        marshalling of assets and liabilities or similar proceedings of or
        relating to the Master Servicer or all or substantially all of the
        property of the Master Servicer; or

                      (5) the Master Servicer shall admit in writing its
        inability to pay its debts generally as they become due, file a petition
        to take advantage of, or commence a voluntary case under, any applicable
        insolvency or reorganization statute, make an assignment for the benefit
        of its creditors, or voluntarily suspend payment of its obligations; or

                      (6) the Master Servicer shall fail to reimburse in full
        the Trustee not later than 6:00 p.m. (New York time) on the Business Day
        following the related Distribution Date for any Advance made by the
        Trustee pursuant to Section 4.01(d) together with accrued and unpaid
        interest.

               If an Event of Default shall occur, then, and in each and every
such case, so long as such Event of Default shall not have been remedied, the
Trustee shall, but only at the direction of either the NIM Insurer or the
Holders of Certificates evidencing not less than 25% of the Voting Rights
evidenced by the Certificates , by notice in writing to the Master Servicer
(with a copy to each Rating Agency), terminate all of the rights and obligations
of the Master Servicer under this Agreement and in and to the Mortgage Loans and
the proceeds thereof, other than its rights as a Certificateholder hereunder. On
or after the receipt by the Master Servicer of such written notice, all
authority and power of the Master Servicer hereunder, whether with respect to
the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee. The
Trustee shall thereupon make any Advance described in Section 4.01 hereof
subject to Section 3.04 hereof. The Trustee is hereby authorized and empowered
to execute and deliver, on behalf of the Master Servicer, as attorney-in-fact or
otherwise, any and all documents and other instruments, and to do or accomplish
all other acts or things necessary or appropriate to effect the purposes of such
notice of termination, whether to complete the transfer and endorsement or
assignment of the Mortgage Loans and related documents, or otherwise. Unless
expressly provided in such written notice, no such termination shall affect any
obligation of the Master Servicer to pay amounts owed pursuant to Article VIII.
The Master Servicer agrees to cooperate with the Trustee in effecting the
termination of the Master Servicer's responsibilities and rights hereunder,
including, without limitation, the transfer to the Trustee of all cash amounts
which shall at the time be credited to the Certificate Account, or thereafter be
received with respect to the Mortgage Loans. The Trustee shall promptly notify
the Rating Agencies of the occurrence of an Event of Default.

               Notwithstanding any termination of the activities of a Master
Servicer hereunder, such Master Servicer shall be entitled to receive, out of
any late collection of a Scheduled Payment on a Mortgage Loan that was due prior
to the notice terminating such Master Servicer's rights and obligations as
Master Servicer hereunder and received after such notice, that portion thereof
to which such Master Servicer would have been entitled pursuant to Sections
3.08(a)(i) through (viii), and any other amounts payable to such Master Servicer
hereunder the entitlement to which arose prior to the termination of its
activities hereunder.

               Section 7.02  Trustee to Act; Appointment of Successor.

               On and after the time the Master Servicer receives a notice of
termination pursuant to Section 7.01 hereof, the Trustee shall, to the extent
provided in Section 3.04, be the successor to the Master Servicer in its
capacity as servicer under this Agreement and the transactions set forth or
provided for herein and shall be subject to all the responsibilities, duties and
liabilities relating thereto placed on the Master Servicer by the terms and
provisions hereof and applicable law including the obligation to make advances
pursuant to Section 4.01. As compensation therefor, the Trustee shall be
entitled to all fees, costs and expenses relating to the Mortgage Loans that the
Master Servicer would have been entitled to if the Master Servicer had continued
to act hereunder. Notwithstanding the foregoing, if the Trustee has become the
successor to the Master Servicer in accordance with Section 7.01 hereof, the
Trustee may, if it shall be unwilling to so act, or shall, if it is prohibited
by applicable law from making Advances pursuant to Section 4.01 hereof or if it
is otherwise unable to so act, (i) appoint any established mortgage loan
servicing institution reasonably acceptable to the NIM Insurer (as evidenced by
the prior written consent of the NIM Insurer), or (ii) if it is unable for 60
days to appoint a successor servicer reasonably acceptable to the NIM Insurer,
petition a court of competent jurisdiction to appoint any established mortgage
loan servicing institution, the appointment of which does not adversely affect
the then current rating of the Certificates and the NIM Insurer guaranteed notes
(without giving effect to any policy or guaranty provided by the NIM Insurer) by
each Rating Agency as the successor to the Master Servicer hereunder in the
assumption of all or any part of the responsibilities, duties or liabilities of
the Master Servicer hereunder. Any successor Master Servicer shall be an
institution that is a Fannie Mae and Freddie Mac approved seller/servicer in
good standing, that has been approved by the Mortgage Insurer if required, that
has a net worth of at least $15,000,000 and that is willing to service the
Mortgage Loans and executes and delivers to the Depositor and the Trustee an
agreement accepting such delegation and assignment, that contains an assumption
by such Person of the rights, powers, duties, responsibilities, obligations and
liabilities of the Master Servicer (other than liabilities and indemnities of
the Master Servicer under Section 6.03 hereof incurred prior to termination of
the Master Servicer under Section 7.01), with like effect as if originally named
as a party to this Agreement; and provided further that each Rating Agency
acknowledges that its rating of the Certificates in effect immediately prior to
such assignment and delegation will not be qualified or reduced as a result of
such assignment and delegation. No appointment of a successor to the Master
Servicer hereunder shall be effective until the Trustee shall have consented
thereto, and written notice of such proposed appointment shall have been
provided by the Trustee to each Certificateholder. The Trustee shall not resign
as servicer until a successor servicer has been appointed and has accepted such
appointment. Pending appointment of a successor to the Master Servicer
hereunder, the Trustee, unless the Trustee is prohibited by law from so acting,
shall, subject to Section 3.04 hereof, act in such capacity as herein above
provided. In connection with such appointment and assumption, the Trustee may
make such arrangements for the compensation of such successor out of payments on
Mortgage Loans as it and such successor shall agree; provided that no such
compensation shall be in excess of that permitted the Master Servicer hereunder.
The Trustee and such successor shall take such action, consistent with this
Agreement, as shall be necessary to effectuate any such succession. Neither the
Trustee nor any other successor servicer shall be deemed to be in default
hereunder by reason of any failure to make, or any delay in making, any
distribution hereunder or any portion thereof or any failure to perform, or any
delay in performing, any duties or responsibilities hereunder, in either case

                                     117
<PAGE>

caused by the failure of the Master Servicer to deliver or provide, or any delay
in delivering or providing, any cash, information, documents or records to it.

               Any successor to the Master Servicer as servicer shall give
notice to the NIM Insurer and the Mortgagors of such change of servicer and
shall, during the term of its service as servicer maintain in force the policy
or policies that the Master Servicer is required to maintain pursuant to Section
6.05.

               In connection with the termination or resignation of the Master
Servicer hereunder, either (i) the successor Master Servicer, including the
Trustee if the Trustee is acting as successor Master Servicer, shall represent
and warrant that it is a member of MERS in good standing and shall agree to
comply in all material respects with the rules and procedures of MERS in
connection with the servicing of the Mortgage Loans that are registered with
MERS, or (ii) the predecessor Master Servicer shall cooperate with the successor
Master Servicer in causing MERS to execute and deliver an assignment of Mortgage
in recordable form to transfer the Mortgage from MERS to the Trustee and to
execute and deliver such other notices, documents and other instruments as may
be necessary or desirable to effect a transfer of such Mortgage Loan or
servicing of such Mortgage Loan on the MERS(R) System to the successor Master
Servicer. The predecessor Master Servicer shall file or cause to be filed any
such assignment in the appropriate recording office. The successor Master
Servicer shall cause such assignment to be delivered to the Co-Trustee promptly
upon receipt of the original with evidence of recording thereon or a copy
certified by the public recording office in which such assignment was recorded.

               Section 7.03  Notification to Certificateholders.

               (a) Upon any termination of or appointment of a successor to the
Master Servicer, the Trustee shall give prompt written notice thereof to the
Certificateholders and to each Rating Agency.

               (b) Within 60 days after the occurrence of any Event of Default,
the Trustee shall transmit by mail to all Certificateholders notice of each such
Event of Default hereunder known to the Trustee, unless such Event of Default
shall have been cured or waived.

                                 ARTICLE VIII.
                   CONCERNING THE TRUSTEE AND THE CO-TRUSTEE

               Section 8.01  Duties of Trustee.

               The Trustee, prior to the occurrence of an Event of Default and
after the curing of all Events of Default that may have occurred, shall
undertake to perform such duties and only such duties as are specifically set
forth in this Agreement. In case an Event of Default has occurred and remains
uncured, the Trustee shall exercise such of the rights and powers vested in it
by this Agreement, and use the same degree of care and skill in their exercise
as a prudent person would exercise or use under the circumstances in the conduct
of such person's own affairs.

                                     118
<PAGE>

               The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee (or the Co-Trustee, to the extent provided in this Agreement)
that are specifically required to be furnished pursuant to any provision of this
Agreement shall examine them to determine whether they conform to the
requirements of this Agreement, to the extent provided in this Agreement. If any
such instrument is found not to conform to the requirements of this Agreement in
a material manner, the Trustee shall take action as it deems appropriate to have
the instrument corrected.

               No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own grossly negligent action, its own gross
negligent failure to act or its own misconduct, its grossly negligent failure to
perform its obligations in compliance with this Agreement, or any liability that
would be imposed by reason of its willful misfeasance or bad faith; provided
that:

                      (1) prior to the occurrence of an Event of Default, and
        after the curing of all such Events of Default that may have occurred,
        the duties and obligations of the Trustee shall be determined solely by
        the express provisions of this Agreement, the Trustee shall not be
        liable, individually or as Trustee, except for the performance of such
        duties and obligations as are specifically set forth in this Agreement,
        no implied covenants or obligations shall be read into this Agreement
        against the Trustee and the Trustee may conclusively rely, as to the
        truth of the statements and the correctness of the opinions expressed
        therein, upon any certificates or opinions furnished to the Trustee and
        conforming to the requirements of this Agreement that it reasonably
        believed in good faith to be genuine and to have been duly executed by
        the proper authorities respecting any matters arising hereunder;

                      (2) the Trustee shall not be liable, individually or as
        Trustee, for an error of judgment made in good faith by a Responsible
        Officer or Responsible Officers of the Trustee, unless the Trustee was
        grossly negligent or acted in bad faith or with willful misfeasance;

                      (3) the Trustee shall not be liable, individually or as
        Trustee, with respect to any action taken, suffered or omitted to be
        taken by it in good faith in accordance with the direction of the
        Holders of each Class of Certificates evidencing not less than 25% of
        the Voting Rights of such Class relating to the time, method and place
        of conducting any proceeding for any remedy available to the Trustee, or
        exercising any trust or power conferred upon the Trustee under this
        Agreement; and

                      (4) without in any way limiting the provisions of this
        Section 8.01 or Section 8.02 hereof, the Trustee shall be entitled to
        rely conclusively on the information delivered to it by the Master
        Servicer in a Trustee Advance Notice in determining whether or not it is
        required to make an Advance under Section 4.01(d), shall have no
        responsibility to ascertain or confirm any information contained in any
        Trustee Advance Notice, and shall have no obligation to make any Advance
        under Section 4.01(d) in the absence of a Trustee Advance Notice or
        actual knowledge by a Responsible Officer that (A) a required Advance
        was not made and (B) such required Advance was not a Nonrecoverable
        Advance.

               Section 8.02  Certain Matters Affecting the Trustee.

               (a)    Except as otherwise provided in Section 8.01:

                      (1) the Trustee may request and rely upon and shall be
        protected in acting or refraining from acting upon any resolution,
        Officer's Certificate, certificate of auditors or any other certificate,
        statement, instrument, opinion, report, notice, request, consent, order,
        appraisal, bond or other paper or document believed by it to be genuine
        and to have been signed or presented by the proper party or parties;

                      (2) the Trustee may consult with counsel and any Opinion
        of Counsel shall be full and complete authorization and protection in
        respect of any action taken or suffered or omitted by it hereunder in
        good faith and in accordance with such Opinion of Counsel;

                      (3) the Trustee shall not be liable, individually or as
        Trustee, for any action taken, suffered or omitted by it in good faith
        and believed by it to be authorized or within the discretion or rights
        or powers conferred upon it by this Agreement;

                      (4) prior to the occurrence of an Event of Default
        hereunder and after the curing of all Events of Default that may have
        occurred, the Trustee shall not be bound to make any investigation into
        the facts or matters stated in any resolution, certificate, statement,
        instrument, opinion, report, notice, request, consent, order, approval,
        bond or other paper or document, unless requested in writing so to do by
        the NIM Insurer or the Holders of each Class of Certificates evidencing
        not less than 25% of the Voting Rights of such Class; provided, however,
        that if the payment within a reasonable time to the Trustee of the
        costs, expenses or liabilities likely to be incurred by it in the making
        of such investigation is, in the opinion of the Trustee not reasonably
        assured to the Trustee by such Certificateholders, the Trustee may
        require reasonable indemnity against such expense, or liability from
        such Certificateholders as a condition to taking any such action;

                      (5) the Trustee may execute any of the trusts or powers
        hereunder or perform any duties hereunder either directly or by or
        through agents, accountants or attorneys;

                      (6) the Trustee shall not be required to expend its own
        funds or otherwise incur any financial liability in the performance of
        any of its duties hereunder if it shall have reasonable grounds for
        believing that repayment of such funds or adequate indemnity against
        such liability is not assured to it;

                      (7) the Trustee shall not be liable, individually or as
        Trustee, for any loss on any investment of funds pursuant to this
        Agreement (other than as issuer of the investment security);

                      (8) the Trustee shall not be deemed to have knowledge of
        an Event of Default until a Responsible Officer of the Trustee shall
        have received written notice thereof; and

                                     120
<PAGE>

                      (9) the Trustee shall be under no obligation to exercise
        any of the trusts or powers vested in it by this Agreement or to make
        any investigation of matters arising hereunder or to institute, conduct
        or defend any litigation hereunder or in relation hereto at the request,
        order or direction of the NIM Insurer or any of the Certificateholders,
        pursuant to the provisions of this Agreement, unless the NIM Insurer or
        such Certificateholders, as applicable, shall have offered to the
        Trustee reasonable security or indemnity against the costs, expenses and
        liabilities that may be incurred therein or thereby.

               (b) All rights of action under this Agreement or under any of the
Certificates, enforceable by the Trustee, may be enforced by the Trustee without
the possession of any of the Certificates, or the production thereof at the
trial or other proceeding relating thereto, and any such suit, action or
proceeding instituted by the Trustee shall be brought in its name for the
benefit of all the Holders of the Certificates, subject to the provisions of
this Agreement.

               Section 8.03  Trustee Not Liable for Mortgage Loans.

               The recitals contained herein shall be taken as the statements of
the Depositor or the Master Servicer, as the case may be, and the Trustee
assumes no responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Agreement or of any
Mortgage Loan or related document or of MERS or the MERS(R) System other than
with respect to the Trustee's execution and authentication of the Certificates.
The Trustee shall not be accountable for the use or application by the Depositor
or the Master Servicer of any funds paid to the Depositor or the Master Servicer
in respect of the Mortgage Loans or deposited in or withdrawn from the
Certificate Account by the Depositor or the Master Servicer.

               Section 8.04  Trustee May Own Certificates.

               The Trustee in its individual or any other capacity may become
the owner or pledgee of Certificates with the same rights as it would have if it
were not the Trustee.

               Section 8.05  Master Servicer to Pay Trustee's Fees and Expenses.

               The Master Servicer covenants and agrees to pay or reimburse the
Trustee, upon its request, for all reasonable expenses, disbursements and
advances incurred or made by the Trustee on behalf of the Trust Fund in
accordance with any of the provisions of this Agreement (including, without
limitation: (A) the reasonable compensation and the expenses and disbursements
of its counsel, but only for representation of the Trustee acting in its
capacity as Trustee hereunder and (B) to the extent that the Trustee must engage
persons not regularly in its employ to perform acts or services on behalf of the
Trust Fund, which acts or services are not in the ordinary course of the duties
of a trustee, paying agent or certificate registrar, in the absence of a breach
or default by any party hereto, the reasonable compensation, expenses and
disbursements of such persons, except any such expense, disbursement or advance
as may arise from its negligence, bad faith or willful misconduct). The Trustee
and any director, officer, employee or agent of the Trustee shall be indemnified
by the Master Servicer and held harmless against any loss, liability or expense
(i) incurred in connection with any legal action relating to

                                     121
<PAGE>

this Agreement or the Certificates, or in connection with the performance of
any of the Trustee's duties hereunder, other than any loss, liability or
expense incurred by reason of willful misfeasance, bad faith or negligence in
the performance of any of the Trustee's duties hereunder or by reason of
reckless disregard of the Trustee's obligations and duties hereunder or (ii)
resulting from any error in any tax or information return prepared by the
Master Servicer. Such indemnity shall survive the termination of this
Agreement or the resignation or removal of the Trustee hereunder.

               Section 8.06  Eligibility Requirements for Trustee.

               The Trustee hereunder shall, at all times, be a corporation or
association organized and doing business under the laws of a state or the United
States of America, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $50,000,000, subject
to supervision or examination by federal or state authority and with a credit
rating that would not cause any of the Rating Agencies to reduce their
respective ratings of any Class of Certificates below the ratings issued on the
Closing Date (or having provided such security from time to time as is
sufficient to avoid such reduction). If such corporation or association
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 8.06 the combined capital and surplus of such
corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 8.06, the Trustee shall resign immediately in the
manner and with the effect specified in Section 8.07 hereof. The corporation or
national banking association serving as Trustee may have normal banking and
trust relationships with the Depositor, the Sellers and the Master Servicer and
their respective affiliates; provided that such corporation cannot be an
affiliate of the Master Servicer other than the Trustee in its role as successor
to the Master Servicer.

               Section 8.07  Resignation and Removal of Trustee.

               The Trustee may at any time resign and be discharged from the
trusts hereby created by (1) giving written notice of resignation to the
Depositor and the Master Servicer and by mailing notice of resignation by first
class mail, postage prepaid, to the Certificateholders at their addresses
appearing on the Certificate Register and each Rating Agency, not less than 60
days before the date specified in such notice when, subject to Section 8.08,
such resignation is to take effect, and (2) acceptance of appointment by a
successor trustee in accordance with Section 8.08 and meeting the qualifications
set forth in Section 8.06. If no successor trustee shall have been so appointed
and have accepted appointment within 30 days after the giving of such notice or
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee.

               If at any time (i) the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.06 hereof and shall fail to resign
after written request thereto by the NIM Insurer or the Depositor, (ii) the
Trustee shall become incapable of acting, or shall be adjudged as bankrupt or
insolvent, or a receiver of the Trustee or of its property shall be appointed,
or any public officer shall take charge or control of the Trustee or of its
property or affairs for the

                                     122
<PAGE>

purpose of rehabilitation, conservation or liquidation, or (iii)(A) a tax is
imposed with respect to the Trust Fund by any state in which the Trustee or
the Trust Fund is located, (B) the imposition of such tax would be avoided by
the appointment of a different trustee and (C) the Trustee fails to indemnify
the Trust Fund against such tax, then the Depositor, the NIM Insurer or the
Master Servicer may remove the Trustee and appoint a successor trustee,
reasonably acceptable to the NIM Insurer, by written instrument, in
triplicate, one copy of which instrument shall be delivered to the Trustee,
one copy of which shall be delivered to the Master Servicer and one copy of
which shall be delivered to the successor trustee.

               The Holders evidencing at least 51% of the Voting Rights of each
Class of Certificates may at any time remove the Trustee and appoint a successor
trustee by written instrument or instruments, in triplicate, signed by such
Holders or their attorneys-in-fact duly authorized, one complete set of which
instruments shall be delivered by the successor Trustee to the Master Servicer
one complete set to the Trustee so removed and one complete set to the successor
so appointed. Notice of any removal of the Trustee shall be given to each Rating
Agency by the successor Trustee.

               Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 8.07 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 8.08 hereof.

               Section 8.08  Successor Trustee.

               Any successor trustee appointed as provided in Section 8.07
hereof shall execute, acknowledge and deliver to the Depositor, its predecessor
trustee and the Master Servicer an instrument accepting such appointment
hereunder and thereupon the resignation or removal of the predecessor trustee
shall become effective and such successor trustee, without any further act, deed
or conveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with the like effect as if originally
named as trustee herein.

               No successor trustee shall accept appointment as provided in this
Section 8.08 unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 8.06 hereof, is reasonably
acceptable to the NIM Insurer and its appointment shall not adversely affect the
then current ratings of the Certificates.

               Upon acceptance of appointment by a successor trustee as provided
in this Section 8.08, the Depositor shall mail notice of the succession of such
trustee hereunder to the NIM Insurer and all Holders of Certificates. If the
Depositor fails to mail such notice within ten days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Depositor.

               Section 8.09  Merger or Consolidation of Trustee.

               Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to substantially all of the corporate trust business
of the Trustee, shall be the successor of the

                                     123
<PAGE>

Trustee hereunder, provided that such corporation shall be eligible under the
provisions of Section 8.06 hereof without the execution or filing of any paper
or further act on the part of any of the parties hereto, anything herein to
the contrary notwithstanding.

               Section 8.10 Appointment of Co-Trustee or Separate Trustee.

               Notwithstanding any other provisions of this Agreement, at any
time, for the purpose of meeting any legal requirements of any jurisdiction in
which any part of the Trust Fund or property securing any Mortgage Note may at
the time be located, the Master Servicer and the Trustee acting jointly shall
have the power and shall execute and deliver all instruments to appoint one or
more Persons approved by the Trustee and reasonably acceptable to the NIM
Insurer to act as co-trustee or co-trustees jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of the Trust Fund, and
to vest in such Person or Persons, in such capacity and for the benefit of the
Certificateholders, such title to the Trust Fund or any part thereof, whichever
is applicable, and, subject to the other provisions of this Section 8.10, such
powers, duties, obligations, rights and trusts as the Master Servicer and the
Trustee may consider necessary or desirable. If the Master Servicer shall not
have joined in such appointment within 15 days after receipt by it of a request
to do so, or in the case an Event of Default shall have occurred and be
continuing, the Trustee shall have the power to make such appointment. No
co-trustee or separate trustee hereunder shall be required to meet the terms of
eligibility as a successor trustee under Section 8.06 and no notice to
Certificateholders of the appointment of any co-trustee or separate trustee
shall be required under Section 8.08.

               Every separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:
                      (1) All rights, powers, duties and obligations conferred
        or imposed upon the Trustee, except for the obligation of the Trustee
        under this Agreement to advance funds on behalf of the Master Servicer,
        shall be conferred or imposed upon and exercised or performed by the
        Trustee and such separate trustee or co-trustee jointly (it being
        understood that such separate trustee or co-trustee is not authorized to
        act separately without the Trustee joining in such act), except to the
        extent that under any law of any jurisdiction in which any particular
        act or acts are to be performed (whether as Trustee hereunder or as
        successor to the Master Servicer hereunder), the Trustee shall be
        incompetent or unqualified to perform such act or acts, in which event
        such rights, powers, duties and obligations (including the holding of
        title to the Trust Fund or any portion thereof in any such jurisdiction)
        shall be exercised and performed singly by such separate trustee or
        co-trustee, but solely at the direction of the Trustee;

                      (2) No trustee hereunder shall be held personally liable
        by reason of any act or omission of any other trustee hereunder; and

                      (3) The Trustee may at any time accept the resignation of
        or remove any separate trustee or co-trustee.

               Any notice, request or other writing given to the Trustee shall
be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each

                                     124
<PAGE>

of them. Every instrument appointing any separate trustee or co-trustee shall
refer to this Agreement and the conditions of this Article VIII. Each separate
trustee and co-trustee upon its acceptance of the trusts conferred, shall be
vested with the estates or property specified in its instrument of
appointment, either jointly with the Trustee or separately, as may be provided
therein, subject to all the provisions of this Agreement, specifically
including every provision of this Agreement relating to the conduct of,
affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee and a copy thereof given to
the Master Servicer and the Depositor.

               Any separate trustee or co-trustee may, at any time, constitute
the Trustee its agent or attorney-in-fact, with full power and authority, to the
extent not prohibited by law, to do any lawful act under or in respect of this
Agreement on its behalf and in its name. If any separate trustee or co-trustee
shall die, become incapable of acting, resign or be removed, all of its estates,
properties, rights, remedies and trusts shall vest in and be exercised by the
Trustee, to the extent permitted by law, without the appointment of a new or
successor trustee.

               Section 8.11  Tax Matters.

               It is intended that the Trust Fund shall constitute, and that the
affairs of the Trust Fund shall be conducted so that each REMIC created pursuant
to the Preliminary Statement qualifies as, a "real estate mortgage investment
conduit" as defined in and in accordance with the REMIC Provisions. In
furtherance of such intention, the Trustee covenants and agrees that it shall
act as agent (and the Trustee is hereby appointed to act as agent) on behalf of
the Trust Fund and that in such capacity it shall: (a) prepare and file, or
cause to be prepared and filed, in a timely manner, a U.S. Real Estate Mortgage
Investment Conduit Income Tax Returns (Form 1066 or any successor form adopted
by the Internal Revenue Service) and prepare and file or cause to be prepared
and filed with the Internal Revenue Service and applicable state or local tax
authorities income tax or information returns for each taxable year with respect
to each REMIC created hereunder containing such information and at the times and
in the manner as may be required by the Code or state or local tax laws,
regulations, or rules, and furnish or cause to be furnished to
Certificateholders the schedules, statements or information at such times and in
such manner as may be required thereby; (b) within thirty days of the Closing
Date, furnish or cause to be furnished to the Internal Revenue Service, on Forms
8811 or as otherwise may be required by the Code, the name, title, address, and
telephone number of the person that the Holders of the Certificates may contact
for tax information relating thereto, together with such additional information
as may be required by such Form, and update such information at the time or
times in the manner required by the Code for the Trust Fund; (c) make or cause
to be made elections, on behalf of each REMIC created hereunder to be treated as
a REMIC on the federal tax return of each such REMIC for its first taxable year
(and, if necessary, under applicable state law); (d) prepare and forward, or
cause to be prepared and forwarded, to the Certificateholders and to the
Internal Revenue Service and, if necessary, state tax authorities, all
information returns and reports as and when required to be provided to them in
accordance with the REMIC Provisions, including without limitation, the
calculation of any original issue discount using the Prepayment Assumption; (e)
provide information necessary for the computation of tax imposed on the transfer
of a Class A-R Certificate to a Person that is not a Permitted Transferee, or an
agent (including a broker, nominee or other middleman) of a Non-Permitted
Transferee, or a pass-through entity in which a Non-Permitted Transferee is the
record holder of an interest (the

                                     125
<PAGE>

reasonable cost of computing and furnishing such information may be charged to
the Person liable for such tax); (f) to the extent that they are under its
control conduct the affairs of the Trust Fund at all times that any
Certificates are outstanding so as to maintain the status of each REMIC
created hereunder as a REMIC under the REMIC Provisions; (g) not knowingly or
intentionally take any action or omit to take any action that would cause the
termination of the REMIC status of any REMIC created hereunder; (h) pay, from
the sources specified in the penultimate paragraph of this Section 8.11, the
amount of any federal, state and local taxes, including prohibited transaction
taxes as described below, imposed on any REMIC created hereunder prior to the
termination of the Trust Fund when and as the same shall be due and payable
(but such obligation shall not prevent the Trustee or any other appropriate
Person from contesting any such tax in appropriate proceedings and shall not
prevent the Trustee from withholding payment of such tax, if permitted by law,
pending the outcome of such proceedings); (i) sign or cause to be signed
federal, state or local income tax or information returns; (j) maintain
records relating to each REMIC created hereunder, including but not limited to
the income, expenses, assets and liabilities of each such REMIC, and the fair
market value and adjusted basis of the Trust Fund property determined at such
intervals as may be required by the Code, as may be necessary to prepare the
foregoing returns, schedules, statements or information; and (k) as and when
necessary and appropriate, represent the Trust Fund in any administrative or
judicial proceedings relating to an examination or audit by any governmental
taxing authority, request an administrative adjustment as to any taxable year
of any REMIC created hereunder, enter into settlement agreements with any
governmental taxing agency, extend any statute of limitations relating to any
tax item of the Trust Fund, and otherwise act on behalf of any REMIC created
hereunder in relation to any tax matter involving any such REMIC.

               In order to enable the Trustee to perform its duties as set forth
herein, the Depositor shall provide, or cause to be provided, to the Trustee
within 10 days after the Closing Date all information or data that the Trustee
requests in writing and determines to be relevant for tax purposes to the
valuations and offering prices of the Certificates, including, without
limitation, the price, yield, prepayment assumption and projected cash flows of
the Certificates and the Mortgage Loans (and, to the extent not part of the
aforementioned, the information referred to in paragraphs (1), (2), (3) and (4)
of Section 4.05(d)). Thereafter, the Depositor shall provide to the Trustee
promptly upon written request therefor, any such additional information or data
that the Trustee may, from time to time, request in order to enable the Trustee
to perform its duties as set forth herein. The Depositor hereby indemnifies the
Trustee for any losses, liabilities, damages, claims or expenses of the Trustee
arising from any errors or miscalculations of the Trustee that result from any
failure of the Depositor to provide, or to cause to be provided, accurate
information or data to the Trustee on a timely basis.

               In the event that any tax is imposed on "prohibited transactions"
of the Trust Fund as defined in section 860F(a)(2) of the Code, on the "net
income from foreclosure property" of the Trust Fund as defined in section
860G(c) of the Code, on any contribution to the Trust Fund after the startup day
pursuant to section 860G(d) of the Code, or any other tax is imposed, including,
without limitation, any federal, state or local tax or minimum tax imposed upon
the Trust Fund pursuant to sections 23153 and 24872 of the California Revenue
and Taxation Code if not paid as otherwise provided for herein, such tax shall
be paid by (i) the Trustee, if any such other tax arises out of or results from
a breach by the Trustee of any of its obligations under this Agreement, (ii) (x)
the Master Servicer, in the case of any such minimum tax, and (y) any party

                                     126
<PAGE>

hereto (other than the Trustee) to the extent any such other tax arises out of
or results from a breach by such other party of any of its obligations under
this Agreement or (iii) in all other cases, or in the event that any liable
party here fails to honor its obligations under the preceding clauses (i) or
(ii), any such tax will be paid first with amounts otherwise to be distributed
to the Class A-R Certificateholders, and second with amounts otherwise to be
distributed to all other Certificateholders in the same manner as if such tax
were a Realized Loss. Notwithstanding anything to the contrary contained herein,
to the extent that such tax is payable by the Class A-R Certificates, the
Trustee is hereby authorized to retain on any Distribution Date, from the
Holders of the Class A-R Certificates (and, if necessary, second, from the
Holders of the all other Certificates in the priority specified in the preceding
sentence), funds otherwise distributable to such Holders in an amount sufficient
to pay such tax. The Trustee agrees to promptly notify in writing the party
liable for any such tax of the amount thereof and the due date for the payment
thereof.

               The Trustee shall treat the Carryover Reserve Fund as an outside
reserve fund within the meaning of Treasury Regulation 1.860G-2(h) that is owned
by the Holders of the Class C Certificates, and that is not an asset of any
REMIC created hereunder. The Trustee shall treat the rights of the Holders of
each Class of Certificates (other than the Class P and Class A-R Certificates)
to receive payments from the Carryover Reserve Fund as rights in an interest
rate corridor contract written by: (i) the Corridor Contract Counterparty in
respect of any Net Rate Carryover funded by the Corridor Contract and in respect
of any residual payments from the Corridor Contract received by the Class C
Certificates, and (ii) the holders of the Class C Certificates in respect of any
monies distributed pursuant to Section 4.04(d)(16) and (17) and Section 4.08(c)
herein, in favor of the other Certificateholders. Thus, each Certificate (other
than the Class P and Class A-R Certificates) shall be treated as representing
ownership of not only an Master REMIC regular interest, but also ownership of an
interest in an interest rate corridor contract. For purposes of determining the
issue price of the Master REMIC regular interests, the Trustee shall assume that
the Corridor Contract has a value of $1,814,500.

               Section 8.12  Co-Trustee.

               (a) The Co-Trustee, upon receipt of all resolutions,
certificates, statements, opinions, reports, documents, orders or other
instruments furnished to the Co-Trustee that are specifically required to be
furnished pursuant to any provision of this Agreement shall examine them to
determine whether they conform to the requirements of this Agreement, to the
extent required by this Agreement. If any such instrument is found not to
conform to the requirements of this Agreement in a material manner, the
Co-Trustee shall take action as it deems appropriate to have the instrument
corrected. In addition, the Co-Trustee shall act as the insured under the
Mortgage Insurance Policy and hereby directs the Master Servicer, on behalf of
the Co-Trustee, to take all actions appropriate or required of the Co-Trustee
under the Mortgage Insurance Policy, other than the payment of the Mortgage
Insurance Premium and obtaining the approval of the Mortgage Insurer with
respect to the appointment of a successor servicer.

               (b) No provision of this Agreement shall be construed to relieve
the Co-Trustee from liability for its own grossly negligent action, its own
gross negligent failure to act or its own misconduct, its grossly negligent
failure to perform its obligations in compliance with

                                     127
<PAGE>

this Agreement, or any liability that would be imposed by reason of its
willful misfeasance or bad faith; provided that:

                      (1) the duties and obligations of the Co-Trustee shall be
        determined solely by the express provisions of this Agreement with the
        exception of Section 8.10, the Co-Trustee shall not be liable,
        individually or as Co-Trustee, except for the performance of such duties
        and obligations as are specifically set forth in this Agreement, no
        implied covenants or obligations shall be read into this Agreement
        against the Co-Trustee and the Co-Trustee may conclusively rely, as to
        the truth of the statements and the correctness of the opinions
        expressed therein, upon any certificates or opinions furnished to the
        Co-Trustee and conforming to the requirements of this Agreement that it
        reasonably believed in good faith to be genuine and to have been duly
        executed by the proper authorities respecting any matters arising
        hereunder; and

                      (2) the Co-Trustee shall not be liable, individually or as
        Co-Trustee, for an error of judgment made in good faith by a Responsible
        Officer or Responsible Officers of the Trustee, unless the Co-Trustee
        was grossly negligent or acted in bad faith or with willful misfeasance.

               (c)    Except as otherwise provided in paragraph (b) above:

                      (1) the Co-Trustee may request and rely upon and shall be
        protected in acting or refraining from acting upon any resolution,
        Officer's Certificate, certificate of auditors or any other certificate,
        statement, instrument, opinion, report, notice, request, consent, order,
        appraisal, bond or other paper or document believed by it to be genuine
        and to have been signed or presented by the proper party or parties;

                      (2) the Co-Trustee may consult with counsel and any
        Opinion of Counsel shall be full and complete authorization and
        protection in respect of any action taken or suffered or omitted by it
        hereunder in good faith and in accordance with such Opinion of Counsel;

                      (3) the Co-Trustee shall not be liable, individually or as
        Co-Trustee, for any action taken, suffered or omitted by it in good
        faith and believed by it to be authorized or within the discretion or
        rights or powers conferred upon it by this Agreement;

                      (4) the Co-Trustee shall not be bound to make any
        investigation into the facts or matters stated in any resolution,
        certificate, statement, instrument, opinion, report, notice, request,
        consent, order, approval, bond or other paper or document;

                      (5) the Co-Trustee may execute any of the trusts or powers
        hereunder or perform any duties hereunder either directly or by or
        through agents, accountants or attorneys; and

                      (6) the Co-Trustee shall not be required to expend its own
        funds or otherwise incur any financial liability in the performance of
        any of its duties hereunder if

                                     128
<PAGE>

        it shall have reasonable grounds for believing that repayment of such
        funds or adequate indemnity against such liability is not assured to it.

               (d) The recitals contained herein shall be taken as the
statements of the Depositor or the Master Servicer, as the case may be, and the
Co-Trustee assumes no responsibility for their correctness. The Co-Trustee makes
no representations as to the validity or sufficiency of this Agreement or of any
Mortgage Loan or related document or of MERS or the MERS(R) System. The
Co-Trustee shall not be accountable for the use or application by the Depositor
or the Master Servicer of any funds paid to the Depositor or the Master Servicer
in respect of the Mortgage Loans or deposited in or withdrawn from the
Certificate Account by the Depositor or the Master Servicer.

               (e) The Co-Trustee in its individual or any other capacity may
become the owner or pledgee of Certificates with the same rights as it would
have if it were not the Co-Trustee.

               (f) The Master Servicer covenants and agrees (i) to pay to the
Co-Trustee from time to time, and the Co-Trustee shall be entitled to, such
compensation as shall be agreed in writing by the Master Servicer and the
Co-Trustee (which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust) for all services rendered by it
in the execution of the trusts hereby created and in the exercise and
performance of any of the powers and duties hereunder of the Co-Trustee and (ii)
to pay or reimburse the Co-Trustee, upon its request, for all reasonable
expenses, disbursements and advances incurred or made by the Co-Trustee on
behalf of the Trust Fund in accordance with any of the provisions of this
Agreement (including, without limitation: (A) the reasonable compensation and
the expenses and disbursements of its counsel, but only for representation of
the Co-Trustee acting in its capacity as Co-Trustee hereunder and (B) to the
extent that the Co-Trustee must engage persons not regularly in its employ to
perform acts or services on behalf of the Trust Fund, which acts or services are
not in the ordinary course of the duties of a trustee, paying agent or
certificate registrar, in the absence of a breach or default by any party
hereto, the reasonable compensation, expenses and disbursements of such persons,
except any such expense, disbursement or advance as may arise from its
negligence, bad faith or willful misconduct). The Co-Trustee and any director,
officer, employee or agent of the Co-Trustee shall be indemnified by the Master
Servicer and held harmless against any loss, liability or expense (i) incurred
in connection with any legal action relating to this Agreement or the
Certificates, or in connection with the performance of any of the Co-Trustee's
duties hereunder, other than any loss, liability or expense incurred by reason
of willful misfeasance, bad faith or negligence in the performance of any of the
Co-Trustee's duties hereunder or by reason of reckless disregard of the
Co-Trustee's obligations and duties hereunder and (ii) resulting from any error
in any tax or information return prepared by the Master Servicer. Such indemnity
shall survive the termination of this Agreement or the resignation or removal of
the Co-Trustee hereunder.

               (g) The Co-Trustee hereunder shall, at all times, be a
corporation or association organized and doing business under the laws of a
state or the United States of America, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$50,000,000, subject to supervision or examination by federal or state authority
and with a credit rating that would not cause any of the Rating Agencies to
reduce

                                     129
<PAGE>

their respective ratings of any Class of Certificates below the ratings
issued on the Closing Date (or having provided such security from time to time
as is sufficient to avoid such reduction). If such corporation or association
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 8.12 the combined capital and surplus of such
corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Co-Trustee shall cease to be eligible in accordance with
the provisions of this Section 8.12, the Co-Trustee shall resign immediately in
the manner and with the effect specified in paragraph (h) below. The corporation
or national banking association serving as Co-Trustee may have normal banking
and trust relationships with the Depositor, the Sellers and the Master Servicer
and their respective affiliates; provided that such corporation cannot be an
affiliate of the Master Servicer other than the Trustee in its role as successor
to the Master Servicer.

               (h) The Co-Trustee may at any time resign and be discharged from
the trusts hereby created by giving 30 days prior written notice of resignation
to the Trustee, the Depositor and the Master Servicer. Upon such resignation the
Trustee (x) may appoint a successor Co-Trustee meeting the requirements in
paragraph (g) above and acceptable to the Master Servicer and the NIM Insurer
(in their sole discretion), so long as such Co-Trustee executes and delivers to
the other parties hereto an instrument agreeing to be bound by the provisions of
this Agreement or (y) may if permitted by the Master Servicer (in its sole
discretion) assume the rights and duties of the resigning Co-Trustee so long as
the Trustee executes and delivers an instrument to that effect.

               Section 8.13 Access to Records of the Trustee.

               The Trustee and any Co-Trustee shall afford the Sellers, the
Depositor, the Master Servicer, the NIM Insurer and each Certificate Owner upon
reasonable notice during normal business hours access to all records maintained
by the Trustee or Co-Trustee in respect of its duties under this Agreement and
access to officers of the Trustee responsible for performing its duties. Upon
request, the Trustee or Co-Trustee shall furnish the Depositor, the Master
Servicer, the NIM Insurer and any requesting Certificate Owner with its most
recent financial statements. The Trustee shall cooperate fully with the Sellers,
the Master Servicer, the Depositor, the NIM Insurer and the Certificate Owner
for review and copying any books, documents, or records requested with respect
to the Trustee's and Co-Trustee's respective duties under this Agreement. The
Sellers, the Depositor, the Master Servicer, and the Certificate Owner shall not
have any responsibility or liability for any action for failure to act by the

               If an Event of Default or other material default by the Master
Servicer or the Depositor under this Agreement occurs and is continuing, at the

Rights or the NIM Insurer, the Trustee shall proceed to protect and enforce its
rights and the rights of the Certificateholders or the NIM Insurer under this

Agreement or in aid of the execution of any power granted in this Agreement

                                  ARTICLE IX.
                                  TERMINATION

               Section 9.01  Termination upon Liquidation or Repurchase of all
                             Mortgage Loans.

               Subject to Section 9.03, the Trust Fund shall terminate and the
obligations and responsibilities of the Depositor, the Master Servicer, the
Sellers, the Trustee and the Co-Trustee created hereby shall terminate upon the
earlier of (a) the purchase by the Master Servicer or NIM Insurer (the party
exercising such purchase option, the "Terminator") of all of the Mortgage Loans
(and REO Properties) remaining in the Trust Fund at the price equal to the sum
of (i) 100% of the Stated Principal Balance of each Mortgage Loan in the Trust
Fund (other than in respect of an REO Property), (ii) accrued interest thereon
at the applicable Mortgage Rate (or, if such repurchase is effected by the
Master Servicer, at the applicable Net Mortgage Rate), (iii) the appraised value
of any REO Property in the Trust Fund (up to the Stated Principal Balance of the
related Mortgage Loan), such appraisal to be conducted by an appraiser mutually
agreed upon by the Terminator and the Trustee, and (iv) if the Terminator is the
NIM Insurer, any unreimbursed Servicing Advances, and the principal portion of
any unreimbursed Advances, made on the Mortgage Loans prior to the exercise of
such repurchase and (b) the later of (i) the maturity or other liquidation (or
any Advance with respect thereto) of the last Mortgage Loan remaining in the
Trust Fund and the disposition of all REO Property and (ii) the distribution to
related Certificateholders of all amounts required to be distributed to them
pursuant to this Agreement, as applicable. In no event shall the trusts created
hereby continue beyond the earlier of (i) the expiration of 21 years from the
death of the last survivor of the descendants of Joseph P. Kennedy, the late
Ambassador of the United States to the Court of St. James's, living on the date
hereof and (ii) the Latest Possible Maturity Date.

               The right to purchase all Mortgage Loans and REO Properties by
the Terminator pursuant to clause (a) of the immediately preceding paragraph
shall be conditioned upon (1) the Stated Principal Balance of the Mortgage
Loans, at the time of any such repurchase, aggregating ten percent (10%) or less
of the sum of (x) the aggregate Cut-Off Date Principal Balance of the Initial
Mortgage Loans and (y) the Pre-Funded Amount, and (2) unless the NIM Insurer
otherwise consents, the purchase price for such Mortgage Loans and REO
Properties shall result in a final distribution on any NIM Insurer guaranteed
notes that is sufficient (x) to pay such notes in full and (y) to pay any
amounts due and payable to the NIM Insurer pursuant to the indenture related to
such notes. The NIM Insurer's right to purchase all Mortgage Loans and REO
Properties shall be further conditioned upon the written consent of the Master
Servicer.

               Section 9.02  Final Distribution on the Certificates.

               If on any Determination Date, (i) the Master Servicer determines
that there are no Outstanding Mortgage Loans and no other funds or assets in the
Trust Fund other than the funds

                                     131
<PAGE>

in the Certificate Account, the Master Servicer shall direct the Trustee to
send a final distribution notice promptly to each related Certificateholder or
(ii) the Trustee determines that a Class of Certificates shall be retired
after a final distribution on such Class, the Trustee shall notify the related
Certificateholders within five (5) Business Days after such Determination Date
that the final distribution in retirement of such Class of Certificates is
scheduled to be made on the immediately following Distribution Date. Any final
distribution made pursuant to the immediately preceding sentence will be made
only upon presentation and surrender of the related Certificates at the
Corporate Trust Office of the Trustee. If the Terminator elects to terminate
pursuant to clause (a) of Section 9.01, at least 20 days prior to the date
notice is to be mailed to the affected Certificateholders, such electing party
shall notify the Depositor and the Trustee of the date such electing party
intends to terminate and of the applicable repurchase price of the related
Mortgage Loans and REO Properties.

               Notice of any termination, specifying the Distribution Date on
which related Certificateholders may surrender their Certificates for payment of
the final distribution and cancellation, shall be given promptly by the Trustee
by letter to related Certificateholders mailed not earlier than the 10th day and
no later than the 15th day of the month immediately preceding the month of such
final distribution. Any such notice shall specify (a) the Distribution Date upon
which final distribution on related Certificates will be made upon presentation
and surrender of such Certificates at the office therein designated, (b) the
amount of such final distribution, (c) the location of the office or agency at
which such presentation and surrender must be made and (d) that the Record Date
otherwise applicable to such Distribution Date is not applicable, distributions
being made only upon presentation and surrender of such Certificates at the
office therein specified. The Terminator will give such notice to each Rating
Agency at the time such notice is given to the affected Certificateholders.

               In the event such notice is given, the Master Servicer shall
cause all funds in the Certificate Account to be remitted to the Trustee for
deposit in the Distribution Account on the Business Day prior to the applicable
Distribution Date in an amount equal to the final distribution in respect of the
Certificates. Upon such final deposit and the receipt by the Trustee of a
Request for File Release therefor, the Co-Trustee shall promptly release to the
Master Servicer the Mortgage Files for the Mortgage Loans.

               Upon presentation and surrender of the Certificates, the Trustee
shall cause to be distributed to Certificateholders of each affected Class the
amounts allocable to such Certificates held in the Distribution Account (and, if
applicable, the Carryover Reserve Fund) in the order and priority set forth in
Section 4.04 hereof on the final Distribution Date and in proportion to their
respective Percentage Interests. Notwithstanding the reduction of the
Certificate Principal Balance of any Class of Certificates to zero, such Class
will be outstanding hereunder (solely for the purpose of receiving distributions
(if any) to which it may be entitled pursuant to the terms of this Agreement and
not for any other purpose) until the termination of the respective obligations
and responsibilities of the Depositor, each Seller, the Master Servicer and the
Trustee hereunder in accordance with Article IX.

               In the event that any affected Certificateholders shall not
surrender related Certificates for cancellation within six months after the date
specified in the above mentioned written notice, the Trustee shall give a second
written notice to the remaining Certificateholders

                                     132
<PAGE>

to surrender their related Certificates for cancellation and receive the final
distribution with respect thereto. If within six months after the second
notice all the applicable Certificates shall not have been surrendered for
cancellation, the Trustee may take appropriate steps, or may appoint an agent
to take appropriate steps, to contact the remaining Certificateholders
concerning surrender of their Certificates, and the cost thereof shall be paid
out of the funds and other assets that remain a part of the Trust Fund. If
within one year after the second notice all related Certificates shall not
have been surrendered for cancellation, then the Class A-R Certificates shall
be entitled to all unclaimed funds and other assets that remain subject
hereto.

               Section 9.03  Additional Termination Requirements.

               (a)    In the event the Terminator exercises its purchase option,
the Trust Fund shall be terminated in accordance with the following additional
requirements, unless the Trustee has been supplied with an Opinion of Counsel,
at the expense of the Terminator, to the effect that the failure of the Trust
Fund to comply with the requirements of this Section 9.03 will not (i) result in
the imposition of taxes on "prohibited transactions" of a REMIC, or (ii) cause
any REMIC created hereunder to fail to qualify as a REMIC at any time that any
Certificates are outstanding:

                      (1) The Master Servicer shall establish a 90-day
liquidation period and notify the Trustee thereof, which shall in turn specify
the first day of such period in a statement attached to the Trust Fund's final
Tax Return pursuant to Treasury Regulation Section 1.860F-1. The Master
Servicer shall prepare a plan of complete liquidation and shall otherwise
satisfy all the requirements of a qualified liquidation under Section 860F of
the Code and any regulations thereunder, as evidenced by an Opinion of Counsel
delivered to the Trustee and the Depositor obtained at the expense of the
Terminator;

                      (2) During such 90-day liquidation period, and at or prior
to the time of making the final payment on the Certificates, the Master
Servicer as agent of the Trustee shall sell all of the assets of the Trust
Fund to the Terminator for cash; and

                      (3) At the time of the making of the final payment on the
Certificates, the Trustee shall distribute or credit, or cause to be
distributed or credited, to the Class A-R Certificateholders all cash on hand
(other than cash retained to meet claims) related to such Class of
Certificates, and the Trust Fund shall terminate at that time.

               (b) By their acceptance of the Certificates, the Holders thereof
hereby authorize the Master Servicer to specify the 90-day liquidation period
for the Trust Fund, which authorization shall be binding upon all successor
Certificateholders. The Trustee shall attach a statement to the final federal
income tax return for each of any REMIC created hereunder stating that pursuant
to Treasury Regulation Section 1.860F-1, the first day of the 90-day liquidation
period for each the REMIC was the date on which the Trustee sold the assets of
the Trust Fund to the Terminator.

               (c) The Trustee as agent for each REMIC created hereunder hereby
agrees to adopt and sign such a plan of complete liquidation upon the written
request of the Master Servicer, and the receipt of the Opinion of Counsel
referred to in Section 9.03(a)(1), and together

                                     133
<PAGE>

with the Holders of the Class A-R Certificates agree to take such other action
in connection therewith as may be reasonably requested by the Terminator.

                                  ARTICLE X.

                           MISCELLANEOUS PROVISIONS

               Section 10.01 Amendment.

               This Agreement may be amended from time to time by the Depositor,
the Master Servicer, the Sellers the Co-Trustee and the Trustee with the consent
of the NIM Insurer, without the consent of any of the Certificateholders to cure
any ambiguity, to correct or supplement any provisions herein, to conform this
Agreement to the Prospectus Supplement, or to make such other provisions with
respect to matters or questions arising under this Agreement, as shall not be
inconsistent with any other provisions herein if such action shall not, as
evidenced by an Opinion of Counsel, adversely affect in any material respect the
interests of any Certificateholder; provided that any such amendment shall be
deemed not to adversely affect in any material respect the interests of the
Certificateholders and no such Opinion of Counsel shall be required if the
Person requesting such amendment obtains a letter from each Rating Agency
stating that such amendment would not result in the downgrading or withdrawal of
the respective ratings then assigned to the Certificates, it being understood
and agreed that any such letter in and of itself will not represent a
determination as to the materiality of any such amendment and will represent a
determination only as to the credit issues affecting any such rating. Any
amendment described above, made solely to conform this Agreement to the
Prospectus Supplement shall be deemed not to adversely affect in any material
respect the interests of the Certificateholders. Notwithstanding the foregoing,
no amendment that significantly changes the permitted activities of the trust
created by this Agreement may be made without the consent of Certificateholders
representing not less than 51% of the Voting Rights of each Class of
Certificates affected by such amendment.

               The Trustee, the Co-Trustee, the Depositor, the Master Servicer
and the Sellers with the consent of the NIM Insurer may also at any time and
from time to time amend this Agreement, without the consent of the
Certificateholders, to modify, eliminate or add to any of its provisions to such
extent as shall be necessary or appropriate to maintain the qualification of the
Trust Fund as a REMIC under the Code or to avoid or minimize the risk of the
imposition of any tax on the Trust Fund pursuant to the Code that would be a
claim against the Trust Fund at any time prior to the final redemption of the
Certificates, provided that the Trustee have been provided an Opinion of
Counsel, which opinion shall be an expense of the party requesting such opinion
but in any case shall not be an expense of the Trustee, to the effect that such
action is necessary or appropriate to maintain such qualification or to avoid or
minimize the risk of the imposition of such a tax.

               This Agreement may also be amended from time to time by the
Depositor, the Master Servicer, the Sellers, the Co-Trustee and the Trustee with
the consent of the NIM Insurer and the Holders of each Class of Certificates
affected thereby evidencing not less than 51% of the Voting Rights of such Class
for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Agreement or of modifying in any
manner

                                     134
<PAGE>

the rights of the Holders of Certificates; provided that no such amendment
shall (i) reduce in any manner the amount of, or delay the timing of, payments
required to be distributed on any Certificate without the consent of the
Holder of such Certificate, (ii) adversely affect in any material respect the
interests of the Holders of any Class of Certificates in a manner other than
as described in (i), without the consent of the Holders of Certificates of
such Class evidencing 66% or more of the Voting Rights of such Class, or (iii)
reduce the aforesaid percentages of Certificates the Holders of which are
required to consent to any such amendment without the consent of the Holders
of all such Certificates then outstanding.

               Notwithstanding any contrary provision of this Agreement, Trustee
and the NIM Insurer shall not consent to any amendment to this Agreement unless
each shall have first received an Opinion of Counsel satisfactory to the Trustee
and the NIM Insurer, which opinion shall be an expense of the party requesting
such amendment but in any case shall not be an expense of the Trustee or the NIM
Insurer, to the effect that such amendment will not cause the imposition of any
tax on the Trust Fund or the Certificateholders or cause any REMIC formed
hereunder to fail to qualify as a REMIC at any time that any Certificates are
outstanding.

               Promptly after the execution of any amendment to this Agreement,
the Trustee shall furnish written notification of the substance of such
amendment to each Certificateholder (if the consent of Certificateholdes is
required) and each Rating Agency.

               It shall not be necessary for the consent of Certificateholders
under this Section to approve the particular form of any proposed amendment, but
it shall be sufficient if such consent shall approve the substance thereof. The
manner of obtaining such consents and of evidencing the authorization of the
execution thereof by Certificateholders shall be subject to such reasonable
regulations as the Trustee may prescribe.

               Nothing in this Agreement shall require the Trustee to enter into
an amendment without receiving an Opinion of Counsel, reasonably satisfactory to
the Trustee and the NIM Insurer that (i) such amendment is permitted and is not
prohibited by this Agreement and that all requirements for amending this
Agreement have been complied with; and (ii) either (A) the amendment does not
adversely affect in any material respect the interests of any Certificateholder
or (B) the conclusion set forth in the immediately preceding clause (A) is not
required to be reached pursuant to this Section 10.01.

               Section 10.02 Recordation of Agreement; Counterparts.

               This Agreement is subject to recordation in all appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the properties subject to the Mortgages are
situated, and in any other appropriate public recording office or elsewhere,
such recordation to be effected by the Master Servicer at its expense.

               For the purpose of facilitating the recordation of this Agreement
as herein provided and for other purposes, this Agreement may be executed
simultaneously in any number of counterparts, each of which counterparts shall
be deemed to be an original, and such counterparts shall constitute but one and
the same instrument.

               Section 10.03 Governing Law.

               THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED
BY THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE
AND TO BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND
REMEDIES OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN
ACCORDANCE WITH SUCH LAWS.

               Section 10.04 Intention of Parties.

               It is the express intent of the parties hereto that the
conveyance of the Mortgage Notes, Mortgages, assignments of Mortgages, title
insurance policies and any modifications, extensions and/or assumption
agreements and private mortgage insurance policies relating to the Mortgage
Loans by the Depositor to the Trustee be, and be construed as, an absolute sale
thereof to the Trustee. It is, further, not the intention of the parties that
such conveyance be deemed a pledge thereof by the Depositor to the Trustee.
However, in the event that, notwithstanding the intent of the parties, such
assets are held to be the property of the Depositor, or if for any other reason
this Agreement or any Subsequent Transfer Agreement is held or deemed to create
a security interest in such assets, then (i) this Agreement shall be deemed to
be a security agreement (within the meaning of the Uniform Commercial Code of
the State of New York) with respect to all such assets and security interests
and (ii) the conveyance provided for in this Agreement and any Subsequent
Transfer Agreement shall be deemed to be an assignment and a grant pursuant to
the terms of this Agreement by the Depositor to the Trustee, for the benefit of
the Certificateholders, of a security interest in all of the assets that
constitute the Trust Fund, whether now owned or hereafter acquired.

               The Depositor for the benefit of the Certificateholders and the
NIM Insurer shall, to the extent consistent with this Agreement, take such
actions as may be necessary to ensure that, if this Agreement were deemed to
create a security interest in the assets of the Trust Fund, such security
interest would be deemed to be a perfected security interest of first priority
under applicable law and will be maintained as such throughout the term of the
Agreement. The Depositor shall arrange for filing any Uniform Commercial Code
continuation statements in connection with any security interest granted or
assigned to the Trustee for the benefit of the Certificateholders.

               Section 10.05 Notices.

               (a)    The Trustee shall use its best efforts to promptly provide
notice to each Rating Agency with respect to each of the following of which it
has actual knowledge:

                      (1) Any material change or amendment to this Agreement;

                      (2) The occurrence of any Event of Default that has not
        been cured;

        pursuant to Sections 2.02, 2.03, 2.04 and 3.12; and

                      (5) The final payment to Certificateholders.

               In addition, the Trustee shall promptly furnish to each Rating
Agency copies of the following:

                      (6) Each report to Certificateholders described in Section
        4.05;

               Section 10.06 Severability of Provisions.

               If any one or more of the covenants, agreements, provisions or
terms of this Agreement shall be for any reason whatsoever held invalid, then
such covenants, agreements, provisions or terms shall be deemed severable from
the remaining covenants, agreements, provisions or terms of this Agreement and
shall in no way affect the validity or enforceability of the other provisions of
this Agreement or of the Certificates or the rights of the Holders thereof.

               Section 10.07 Assignment.

               Notwithstanding anything to the contrary contained herein, except
as provided pursuant to Section 6.02, this Agreement may not be assigned by the
Master Servicer without the prior written consent of the Trustee and the
Depositor.

               Section 10.08 Limitation on Rights of Certificateholders.

               The death or incapacity of any Certificateholder shall not
operate to terminate this Agreement or the Trust Fund, nor entitle such
Certificateholder's legal representative or heirs to claim an accounting or to
take any action or commence any proceeding in any court for a petition or
winding up of the Trust Fund, or otherwise affect the rights, obligations and
liabilities of the parties hereto or any of them.

               No Certificateholder shall have any right to vote (except as
provided herein) or in any manner otherwise control the operation and management
of the Trust Fund, or the obligations of the parties hereto, nor shall anything
herein set forth or contained in the terms of the Certificates be construed so
as to constitute the Certificateholders from time to time as partners or members
of an association; nor shall any Certificateholder be under any liability to any
third party by reason of any action taken by the parties to this Agreement
pursuant to any provision hereof.

               No Certificateholder shall have any right by virtue or by
availing itself of any provisions of this Agreement to institute any suit,
action or proceeding in equity or at law upon or under or with respect to this
Agreement, unless such Holder previously shall have given to the Trustee a
written notice of an Event of Default and of the continuance thereof, as
hereinbefore provided, the Holders of Certificates evidencing not less than 25%
of the Voting Rights shall also have made written request to the Trustee to
institute such action, suit or proceeding in its own name as Trustee hereunder
and shall have offered to the Trustee such reasonable indemnity as it may
require against the costs, expenses, and liabilities to be incurred therein or
thereby, and the Trustee, for 60 days after its receipt of such notice, request
and offer of indemnity shall have neglected or refused to institute any such
action, suit or proceeding; it being understood and intended, and being
expressly covenanted by each Certificateholder with every other
Certificateholder and the Trustee, that no one or more Holders of Certificates
shall have any right in any manner whatever by virtue or by availing itself or
themselves of any provisions of this Agreement to affect, disturb or prejudice
the rights of the Holders of any other of the Certificates, or to obtain or seek
to obtain priority over or preference to any other such Holder or to enforce any
right under this Agreement, except in the manner herein provided and for the
common benefit of all Certificateholders. For the protection and enforcement of
the provisions

                                     138

of this Section 10.08, each and every Certificateholder and the Trustee shall
be entitled to such relief as can be given either at law or in equity.

               Section 10.09 Inspection and Audit Rights.

               The Master Servicer agrees that, on reasonable prior notice, it
will permit any representative of the Depositor, either Seller, the NIM Insurer
or the Trustee during the Master Servicer's normal business hours, to examine
all the books of account, records, reports and other papers of the Master
Servicer relating to the Mortgage Loans, to make copies and extracts therefrom,
to cause such books to be audited by independent certified public accountants
selected by the Depositor, a Seller, the NIM Insurer or the Trustee and to
discuss its affairs, finances and accounts relating to the Mortgage Loans with
its officers, employees and independent public accountants (and by this
provision the Master Servicer hereby authorizes such accountants to discuss with
such representative such affairs, finances and accounts), all at such reasonable
times and as often as may be reasonably requested. Any out-of-pocket expense
incident to the exercise by the Depositor, either Seller, the NIM Insurer or the
Trustee of any right under this Section 10.09 shall be borne by the party
requesting such inspection; all other such expenses shall be borne by the Master

               Section 10.10 Certificates Nonassessable and Fully Paid.

               It is the intention of the Depositor that Certificateholders
shall not be personally liable for obligations of the Trust Fund, that the
interests in the Trust Fund represented by the Certificates shall be
nonassessable for any reason whatsoever, and that the Certificates, upon due
authentication thereof by the Trustee pursuant to this Agreement, are and shall
be deemed fully paid.

               Section 10.11 Rights of NIM Insurer.

               (a)    The rights of the NIM Insurer under this Agreement shall
exist only so long as either:

                      (1) the notes certain payments on which are guaranteed by
        the NIM Insurer remain outstanding or

                      (2) the NIM Insurer is owed amounts paid by it with
        respect to that guaranty.

               (b)    The rights of the NIM Insurer under this Agreement are
exercisable by the NIM Insurer only so long as no default by the NIM Insurer
under its guaranty of certain payments under notes backed or secured by the
Class C or Class P Certificates has occurred and is continuing. If the NIM
Insurer is the subject of any insolvency proceeding, the rights of the NIM
Insurer under this Agreement will be exercisable by the NIM Insurer only so long
as:

                      (1) the obligations of the NIM Insurer under its guaranty
        of notes backed or secured by the Class C or Class P Certificates have
        not been disavowed and

                      (2) CHL and the Trustee have received reasonable
        assurances that the NIM Insurer will be able to satisfy its obligations
        under its guaranty of notes backed or secured by the Class C or Class P
        Certificates.

               (c)    The NIM Insurer is a third party beneficiary of this
Agreement to the same extent as if it were a party to this Agreement and may
enforce any of those rights under this Agreement.

               (d)    A copy of any documents of any nature required by this
Agreement to be delivered by the Trustee, or to the Trustee or the Rating
Agencies, shall in each case at the same time also be delivered to the NIM
Insurer. Any notices required to be given by the Trustee, or to the Trustee or
the Rating Agencies, shall in each case at the same time also be given to the
NIM Insurer. If the Trustee receives a notice or document that is required
hereunder to be delivered to the NIM Insurer, and if such notice or document
does not indicate that a copy thereof has been previously sent to the NIM
Insurer, the Trustee shall send the NIM Insurer a copy of such notice or
document. If such document is an Opinion of Counsel, the NIM Insurer shall be an
addressee thereof or such Opinion of Counsel shall contain language permitting
the NIM Insurer to rely thereon as if the NIM Insurer were an addressee thereof.

               (e)    Anything in this Agreement that is conditioned on not
resulting in the downgrading or withdrawal of the ratings then assigned to the
Certificates by the Rating Agencies shall also be conditioned on not resulting
in the downgrading or withdrawal of the ratings then assigned by the Rating
Agencies to the notes backed or secured by the Class C or Class P Certificate
(without giving effect to any policy or guaranty provided by the NIM Insurer).

Gentlemen:

               In accordance with Section 2.02 of the Pooling and Servicing
Agreement dated as of December 1, 2004 (the "Pooling and Servicing Agreement")
among CWABS, Inc., as Depositor, Countrywide Home Loans, Inc., as a Seller,
Park Monaco Inc., as a Seller, Countrywide Home Loans Servicing LP, as Master
Servicer, the undersigned, as Trustee, The Bank of New York Trust Company,
N.A., as Co-Trustee, the undersigned, as Trustee, hereby certifies that, as to
each Mortgage Loan listed in the Mortgage Loan Schedule (other than any
Mortgage Loan paid in full or listed in the attached list of exceptions) the
Co-Trustee has received:

               (i) the original Mortgage Note, endorsed by the applicable Seller
or the originator of such Mortgage Loan, without recourse in the following form:
"Pay to the order of _____________________, without recourse", or, if the
original Mortgage Note has been lost or destroyed and not replaced, an original
lost note affidavit from the applicable Seller, stating that the original
Mortgage Note was lost or destroyed, together with a copy of the related
Mortgage Note; and

               (ii) a duly executed assignment of the Mortgage in the form
permitted by Section 2.01 of the Pooling and Servicing Agreement.

               Based on its review and examination and only as to the foregoing
documents, such documents appear regular on their face and related to such

COUNTY OF             )

               The undersigned, being first duly sworn, deposes and says as
follows:

               1. The undersigned is an officer of _______________, the proposed
Transferee of an Ownership Interest in a Class A-R Certificate (the
"Certificate") issued pursuant to the Pooling and Servicing Agreement, dated as
of December 1, 2004 (the "Agreement"), by and among CWABS, Inc., as depositor
(the "Depositor"), Countrywide Home Loans, Inc., as a Seller, Park Monaco Inc.,
as a Seller, Countrywide Home Loans Servicing LP, as Master Servicer, The Bank
of New York Trust Company, N.A., as Co-Trustee, and The Bank of New York, as
Trustee. Capitalized terms used, but not defined herein or in Exhibit 1 hereto,
shall have the meanings ascribed to such terms in the Agreement. The Transferee
has authorized the undersigned to make this affidavit on behalf of the
Transferee.

               2. The Transferee is not an employee benefit plan that is subject
to Title I of ERISA or to section 4975 of the Internal Revenue Code of 1986, nor
is it acting on behalf of or with plan assets of any such plan. The Transferee
is, as of the date hereof, and will be, as of the date of the Transfer, a
Permitted Transferee. The Transferee will endeavor to remain a Permitted
Transferee for so long as it retains its Ownership Interest in the Certificate.
The Transferee is acquiring its Ownership Interest in the Certificate for its
own account.

               3. The Transferee has been advised of, and understands that (i) a
tax will be imposed on Transfers of the Certificate to Persons that are not
Permitted Transferees; (ii) such tax will be imposed on the transferor, or, if
such Transfer is through an agent (which includes a broker, nominee or
middleman) for a Person that is not a Permitted Transferee, on the agent; and
(iii) the Person otherwise liable for the tax shall be relieved of liability for
the tax if the subsequent Transferee furnished to such Person an affidavit that
such subsequent Transferee is a Permitted Transferee and, at the time of
Transfer, such Person does not have actual knowledge that the affidavit is
false.

               4. The Transferee has been advised of, and understands that a tax
will be imposed on a "pass-through entity" holding the Certificate if at any
time during the taxable year of the pass-through entity a Person that is not a
Permitted Transferee is the record holder of an interest in such entity. The
Transferee understands that such tax will not be imposed for any period with
respect to which the record holder furnishes to the pass-through entity an
affidavit that such record holder is a Permitted Transferee and the pass-through
entity does not have actual knowledge that such affidavit is false. (For this
purpose, a "pass-through entity" includes a regulated investment company, a real
estate investment trust or common trust fund, a partnership, trust or estate,
and certain cooperatives and, except as may be provided in Treasury Regulations,
persons holding interests in pass-through entities as a nominee for another
Person.)

<PAGE>

               5. The Transferee has reviewed the provisions of Section 5.02(c)
of the Agreement (attached hereto as Exhibit 2 and incorporated herein by
reference) and understands the legal consequences of the acquisition of an
Ownership Interest in the Certificate including, without limitation, the
restrictions on subsequent Transfers and the provisions regarding voiding the
Transfer and mandatory sales. The Transferee expressly agrees to be bound by and
to abide by the provisions of Section 5.02(c) of the Agreement and the
restrictions noted on the face of the Certificate. The Transferee understands
and agrees that any breach of any of the representations included herein shall
render the Transfer to the Transferee contemplated hereby null and void.

               6. The Transferee agrees to require a Transfer Affidavit from any
Person to whom the Transferee attempts to Transfer its Ownership Interest in the
Certificate, and in connection with any Transfer by a Person for whom the
Transferee is acting as nominee, trustee or agent, and the Transferee will not
Transfer its Ownership Interest or cause any Ownership Interest to be
Transferred to any Person that the Transferee knows is not a Permitted
Transferee. In connection with any such Transfer by the Transferee, the
Transferee agrees to deliver to the Trustee a certificate substantially in the
form set forth as Exhibit J-1 to the Agreement (a "Transferor Certificate") to
the effect that such Transferee has no actual knowledge that the Person to which
the Transfer is to be made is not a Permitted Transferee.

               7. The Transferee does not have the intention to impede the
assessment or collection of any tax legally required to be paid with respect to
the Class A-R Certificates.

               8. The Transferee's taxpayer identification number is _____.

               9. The Transferee is a U.S. Person as defined in Code section
7701(a)(30).

               10. The Transferee is aware that the Class A-R Certificates may
be "noneconomic residual interests" within the meaning of proposed Treasury
regulations promulgated pursuant to the Code and that the transferor of a
noneconomic residual interest will remain liable for any taxes due with respect
to the income on such residual interest, unless no significant purpose of the
transfer was to impede the assessment or collection of tax. In addition, as the
holder of a noneconomic residual interest, the Transferee may incur tax
liabilities in excess of any cash flows generated by the interest and the
Transferee hereby represents that it intends to pay taxes associated with
holding the residual interest as they become due.

               11. The Transferee has provided financial statements or other
financial information requested by the Transferor in connection with the
transfer of the Class A-R Certificates to permit the Transferor to assess the
financial capability of the Transferee to pay such taxes.

                              Certain Definitions

               "Ownership Interest": As to any Certificate, any ownership
interest in such Certificate, including any interest in such Certificate as the
Holder thereof and any other interest therein, whether direct or indirect, legal
or beneficial.

               "Permitted Transferee": Any person other than (i) the United
States, any State or political subdivision thereof, or any agency or
instrumentality of any of the foregoing, (ii) a foreign government,
International Organization or any agency or instrumentality of either of the
foregoing, (iii) an organization (except certain farmers' cooperatives described
in section 521 of the Code) that is exempt from tax imposed by Chapter 1 of the
Code (including the tax imposed by section 511 of the Code on unrelated business
taxable income) on any excess inclusions (as defined in section 860E(c)(1) of
the Code) with respect to any Class A-R Certificate, (iv) rural electric and
telephone cooperatives described in section 1381(a)(2)(C) of the Code, (v) an
"electing large partnership" as defined in section 775 of the Code, (vi) a
Person that is not a citizen or resident of the United States, a corporation,
partnership, or other entity (treated as a corporation or a partnership for
federal income tax purposes) created or organized in or under the laws of the
United States, any state thereof or the District of Columbia, or an estate whose
income from sources without the United States is includible in gross income for
United States federal income tax purposes regardless of its connection with the
conduct of a trade or business within the United States, or a trust if a court
within the United States is able to exercise primary supervision over the
administration of the trust and one or more United States persons have authority
to control all substantial decisions of the trustor unless such Person has
furnished the transferor and the Trustee with a duly completed Internal Revenue
Service Form W-8ECI, and (vii) any other Person so designated by the Trustee
based upon an Opinion of Counsel that the Transfer of an Ownership Interest in a
Class A-R Certificate to such Person may cause any REMIC formed hereunder to
fail to qualify as a REMIC at any time that any Certificates are Outstanding.
The terms "United States," "State" and "International Organization" shall have
the meanings set forth in section 7701 of the Code or successor provisions. A
corporation will not be treated as an instrumentality of the United States or of
any State or political subdivision thereof for these purposes if all of its
activities are subject to tax and, with the exception of the Federal Home Loan
Mortgage Corporation, a majority of its board of directors is not selected by
such government unit.

partnership, joint venture, bank, joint stock company, trust (including any
beneficiary thereof), unincorporated organization or government or any agency or
political subdivision thereof.

               "Transfer": Any direct or indirect transfer or sale of any
Ownership Interest in a Certificate, including the acquisition of a Certificate
by the Depositor.

                        Section 5.02(c) of the Agreement

               (c) Each Person who has or who acquires any Ownership Interest
in a Class A-R Certificate shall be deemed by the acceptance or acquisition of
such Ownership Interest to have agreed to be bound by the following
provisions, and the rights of each Person acquiring any Ownership Interest in
a Class A-R Certificate are expressly subject to the following provisions:

               (1) Each Person holding or acquiring any Ownership Interest in a
        Class A-R Certificate shall be a Permitted Transferee and shall promptly
        notify the Trustee of any change or impending change in its status as a
        Permitted Transferee.

               (2) Except in connection with any registration in the name of, or
        transfer of a Class A-R Certificate to, an affiliate of the Depositor
        (either directly or through a nominee) on or about the Closing Date, no
        Ownership Interest in a Class A-R Certificate may be registered on the
        Closing Date or thereafter transferred, and the Trustee shall not
        register the Transfer of any Class A-R Certificate unless, the Trustee
        shall have been furnished with an affidavit (a "Transfer Affidavit") of
        the initial owner or the proposed transferee in the form attached hereto
        as Exhibit I.

               (3) Each Person holding or acquiring any Ownership Interest in a
        Class A-R Certificate shall agree (A) to obtain a Transfer Affidavit
        from any other Person to whom such Person attempts to Transfer its
        Ownership Interest in a Class A-R Certificate, (B) to obtain a Transfer
        Affidavit from any Person for whom such Person is acting as nominee,
        trustee or agent in connection with any Transfer of a Class A-R
        Certificate and (C) not to Transfer its Ownership Interest in a Class
        A-R Certificate, or to cause the Transfer of an Ownership Interest in a
        Class A-R Certificate to any other Person, if it has actual knowledge
        that such Person is not a Permitted Transferee.

               (4) Any attempted or purported Transfer of any Ownership Interest
        in a Class A-R Certificate in violation of the provisions of this
        Section 5.02(c) shall be absolutely null and void and shall vest no
        rights in the purported Transferee. If any purported transferee shall
        become a Holder of a Class A-R Certificate in violation of the
        provisions of this Section 5.02(c), then the last preceding Permitted
        Transferee shall be restored to all rights as Holder thereof retroactive
        to the date of registration of Transfer of such Class A-R Certificate.
        The Trustee shall be under no liability to any Person for any
        registration of Transfer of a Class A-R Certificate that is in fact not
        permitted by Section 5.02(b) and this Section 5.02(c) or for making any
        payments due on such Certificate to the Holder thereof or taking any
        other action with respect to such Holder under the provisions of this
        Agreement so long as the Transfer was registered after receipt of the
        related Transfer Affidavit and Transferor Certificate. The Trustee shall
        be entitled but not obligated to recover from any Holder of a Class A-R
        Certificate that was in fact not a Permitted Transferee at the time it
        became a Holder or, at such subsequent time as it became other than a
        Permitted Transferee, all payments made on such Class A-R Certificate at
        and after either such time. Any such payments so recovered by the
        Trustee shall be paid and delivered by the Trustee to the last preceding
        Permitted Transferee of such Certificate.

                                    I-1-5
<PAGE>

               (5) The Master Servicer shall use its best efforts to make
        available, upon receipt of written request from the Trustee, all
        information necessary to compute any tax imposed under section 860E(e)
        of the Code as a result of a Transfer of an Ownership Interest in a
        Class A-R Certificate to any Holder who is not a Permitted Transferee.

               The restrictions on Transfers of a Class A-R Certificate set
forth in this section 5.02(c) shall cease to apply (and the applicable portions
of the legend on a Class A-R Certificate may be deleted) with respect to
Transfers occurring after delivery to the Trustee of an Opinion of Counsel,
which Opinion of Counsel shall not be an expense of the Trustee, the Sellers or
the Master Servicer to the effect that the elimination of such restrictions will
not cause any constituent REMIC of any REMIC formed hereunder to fail to qualify
as a REMIC at any time that the Certificates are outstanding or result in the
imposition of any tax on the Trust Fund, a Certificateholder or another Person.
Each Person holding or acquiring any ownership Interest in a Class A-R
Certificate hereby consents to any amendment of this Agreement that, based on an
Opinion of Counsel furnished to the Trustee, is reasonably necessary (a) to
ensure that the record ownership of, or any beneficial interest in, a Class A-R
Certificate is not transferred, directly or indirectly, to a Person that is not
a Permitted Transferee and (b) to provide for a means to compel the Transfer of
a Class A-R Certificate that is held by a Person that is not a Permitted
Transferee to a Holder that is a Permitted Transferee.

           consolidated with the Buyer in its financial statements prepared in
           accordance with generally accepted accounting principles and if the
           investments of such subsidiaries are managed under the Buyer's
           direction. However, such securities were not included if the Buyer is

           understands that the seller to it and other parties related to the

           made herein because one or more sales to the Buyer may be in reliance
           on Rule 144A.

           notify each of the parties to which this certification is made of any
           changes in the information and conclusions herein. Until such notice

           reaffirmation of this certification as of the date of such purchase.
           In addition, if the Buyer is a bank or savings and loan is provided
           above, the Buyer agrees that it will furnish to such parties updated
           annual financial statements promptly after they become available.

           QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A
           --------------------------------------------------------

          [For Transferees That are Registered Investment Companies]

The undersigned (the "Buyer") hereby certifies as follows to the parties listed
in the Rule 144A Transferee Certificate to which this certification relates with
respect to the Certificates described therein:

               1. As indicated below, the undersigned is the President, Chief
Financial Officer or Senior Vice President of the Buyer or, if the Buyer is a
"qualified institutional buyer" as that term is defined in Rule 144A under the
Securities Act of 1933, as amended ("Rule 144A") because Buyer is part of a
Family of Investment Companies (as defined below), is such an officer of the
Adviser.

        In connection with purchases by Buyer, the Buyer is a "qualified
           institutional buyer" as defined in SEC Rule 144A because (i) the
           Buyer is an investment company registered under the Investment
           Company Act of 1940, as amended and (ii) as marked below, the Buyer
           alone, or the Buyer's Family of Investment Companies, owned at least

           referred to below) as of the end of the Buyer's most recent fiscal
           year. For purposes of determining the amount of securities owned by
           the Buyer or the Buyer's Family of Investment Companies, the cost of
           such securities was used, except (i) where the Buyer or the Buyer's
           Family of Investment Companies reports its securities holdings in its
           financial statements on the basis of their market value, and (ii) no
           current information with respect to the cost of those securities has
           been published. If clause (ii) in the preceding sentence applies, the
           securities may be valued at market.

        ___  The Buyer owned $       in securities (other than the excluded
             securities referred to below) as of the end of the Buyer's most

             with Rule 144A).

        ___  The Buyer is part of a Family of Investment Companies which owned
             in the aggregate $       in securities (other than the excluded
             securities referred to below) as of the end of the Buyer's most
             recent fiscal year (such amount being calculated in accordance with
             Rule 144A).

    The term "Family of Investment Companies" as used herein means two or more
        registered investment companies (or series thereof) that have the same
        investment adviser or investment advisers that are affiliated (by virtue
        of being majority owned subsidiaries of the same parent or because one
        investment adviser is a majority owned subsidiary of the other).

    The term "securities" as used herein does not include (i) securities of
        issuers that are affiliated with the Buyer or are part of the Buyer's
        Family of Investment Companies, (ii) securities issued or guaranteed by
        the U.S. or any instrumentality thereof, (iii) bank deposit notes and
        certificates of deposit, (iv) loan participations, (v) repurchase

<PAGE>

        agreements, (vi) securities owned but subject to a repurchase agreement
        and (vii) currency, interest rate and commodity swaps.

    The Buyer is familiar with Rule 144A and under-stands that the parties
        listed in the Rule 144A Transferee Certificate to which this
        certification relates are relying and will continue to rely on the
        statements made herein because one or more sales to the Buyer will be in
        reliance on Rule 144A. In addition, the Buyer will only purchase for the
        Buyer's own account.

    Until the date of purchase of the Certificates, the undersigned will notify
        the parties listed in the Rule 144A Transferee Certificate to which this
        certification relates of any changes in the information and conclusions
        herein. Until such notice is given, the Buyer's purchase of the
        Certificates will constitute a reaffirmation of this certification by
        the undersigned as of the date of such purchase.

          POOLING AND SERVICING AGREEMENT, dated as of December 1, 2004, by
and among CWABS, INC., a Delaware corporation, as depositor (the "Depositor"),
COUNTRYWIDE HOME LOANS, INC., a New York corporation, as seller (the
"Seller"), COUNTRYWIDE HOME LOANS SERVICING LP, a Texas limited partnership,
as master servicer (the "Master Servicer"), THE BANK OF NEW YORK, a New York
banking corporation, as trustee (the "Trustee"), and WELLS FARGO BANK,
NATIONAL ASSOCIATION, a national banking association, as co-trustee (the
"Co-Trustee").

                             PRELIMINARY STATEMENT

     The Depositor is the owner of the Trust Fund that is hereby conveyed to
the Trustee in return for the Certificates. As provided herein, the Trustee
will elect that the Trust Fund (except for the Corridor Contract, the
Carryover Reserve Fund and the Principal Reserve Fund) be treated for federal
income tax purposes as comprising two real estate mortgage investment conduits
(each a "REMIC" or, in the alternative, the "Lower Tier REMIC" and the "Master
REMIC," respectively). The Lower Tier REMIC will hold as assets all property
of the Trust Fund (other than the Corridor Contract, the Carryover Reserve
Fund and the Principal Reserve Fund) and will be evidenced by (i) the Lower
Tier REMIC Regular Interests, which will be uncertificated and will represent
the "REMIC regular interests" in the Lower Tier REMIC, and (ii) the Class
LT-A-R Interest, which will represent the "REMIC residual interest" in the
Lower Tier REMIC. The Master REMIC will hold as assets the Lower Tier REMIC
Regular Interests and will be evidenced by the Certificates, each of which
(other than the Class A-R Certificate) will represent ownership of one or more
"REMIC regular interests" in the Master REMIC. The Class A-R Certificate will
represent ownership of the sole class of "REMIC residual interest" in each of
the Lower Tier REMIC and the Master REMIC. The latest possible maturity date
of all REMIC regular interests created herein shall be the Latest Possible
Maturity Date.

     The following table specifies the class designation, interest rate, and
principal amount for each class of Lower Tier REMIC Interest:

</TABLE>

(1)  The interest rate with respect to any Distribution Date (and the related
     Accrual Period) for these Lower Tier REMIC Interests is a per annum rate
     equal to the Net Rate Cap.

(2)  The Class A-IO Certificates are entitled to receive on each Distribution
     Date a specified portion of the interest payable on each Lower Tier REMIC
     Interest (other than the LT-A-R Interest). Specifically, for each Accrual
     Period, the Class A-IO Certificates are entitled to interest accruals on
     each Lower Tier REMIC Interest in excess of the interest paid on such
     Lower Tier REMIC Interest's corresponding, non-IO Certificate.

(3)  The LT-A-R Interest will be the sole class of residual interest in the
     Lower Tier REMIC. It does not have an interest rate or a principal
     balance.

     On each Distribution Date, the Trustee shall allocate the losses on, and
distribute the interest and principal on the Mortgage Loans to the Lower Tier
REMIC Interests in the same manner that such items are allocated to or
distributed among the Corresponding Classes of Certificates.

          The following table sets forth characteristics of the Certificates in
the Master REMIC, each of which Certificates, except for the Class A-R
Certificates, is hereby designated as a "regular interest" in the Master
REMIC.

(1)  The Certificates will accrue interest at the related Pass-Through Rates
     identified in this Agreement.

(2)  Notional balance equal to the Class A-IO Notional Balance. No principal
     will be paid on the Class A-IO Certificates.

(3)  The Class A-R Certificate will represent the sole class of residual
     interest in the Master REMIC.

(4)  For each Distribution Date the Class P Certificates are entitled to all
     Prepayment Charges distributed with respect to the P Interests.

     In consideration of the mutual agreements herein contained, the
Depositor, the Master Servicer, the Seller, the Trustee and the Co-Trustee
agree as follows:

     The foregoing REMIC structure is intended to cause all of the cash from
the Mortgage Loans to flow through to the Master REMIC as cash flow on a REMIC
regular interest, without creating any shortfall -- actual or potential (other
than for credit losses) -- to any REMIC regular interest.

                                  DEFINITIONS

          Section 1.01 Defined Terms.

          In addition to those defined terms defined in Section 1.02, whenever
used in this Agreement, the following words and phrases, unless the context
otherwise requires, shall have the following meanings:

          Accrual Period: With respect to the Class A-1 Certificates and any
Distribution Date, the period commencing on the immediately preceding
Distribution Date (or, in the case of the first Distribution Date, the Closing
Date) and ending on the day immediately preceding such Distribution Date. With
respect to each Class of Certificates other than the Class A-1 Certificates,
the calendar month immediately preceding such Distribution Date. All
calculations of interest on the Class A-1 Certificates will be made on the
basis of the actual number of days elapsed in the related Accrual Period and
on a 360 day year. All calculations of interest on each Class of Certificates
other than the Class A-1 Certificates will be made on the basis of a 360-day
year consisting of twelve 30-day months.

          Adjusted Net Mortgage Rate: As to each Mortgage Loan, the Mortgage
Rate less the Expense Fee Rate.

          Advance: The aggregate of the advances required to be made by the
Master Servicer with respect to any Distribution Date pursuant to Section
4.01, the amount of any such advances being equal to the aggregate of payments
of principal and interest (net of the Servicing Fees) on the Mortgage Loans
that were due on the related Due Date and not received by the Master Servicer
as of the close of business on the related Determination Date including an
amount equivalent to interest on each Mortgage Loan as to which the related
Mortgaged Property is an REO Property; provided, however, that with respect to
each REO Property that has not been liquidated, the net monthly rental income
(if any) from such REO Property deposited in the Certificate Account for such
Distribution Date pursuant to Section 3.12 may be used to offset such advance
for the related REO Property.

          (f) [Reserved]

          (g) In connection with the transfer and assignment of each Mortgage

with, the Trustee within the time periods specified in the definition of
"Delay Delivery Mortgage Loans") (except as provided in clause (vi) below) for
the benefit of the Certificateholders, the following documents or instruments
with respect to each such Mortgage Loan so assigned (with respect to each
Mortgage Loan, clause (i) through (vi) below, together, the "Mortgage File"
for each such Mortgage Loan):

               (i) the original Mortgage Note, endorsed by the Seller or the
     originator of such Mortgage Loan, without recourse, in the following
     form: "Pay to the order of ________________ without recourse", with all
     intervening endorsements that show a complete chain of endorsement from
     the originator to the Seller, or, if the original Mortgage Note has been

     Mortgage Loan, the original recorded Mortgage, and in the case of each
     MERS Mortgage Loan, the original Mortgage, noting the presence of the MIN
     of the Mortgage Loan and language indicating that the Mortgage Loan is a

     indicated thereon, or a copy of the Mortgage certified by the public
     recording office in which such Mortgage has been recorded;

               (iii) in the case of each Mortgage Loan that is not a MERS
     Mortgage Loan, a duly executed assignment of the Mortgage to
     "Asset-Backed Certificates, Series 2004-S1, CWABS, Inc., by The Bank of
     New York, a New York banking corporation, as trustee under the Pooling
     and Servicing Agreement dated as of December 1, 2004, without recourse"
     (each such assignment, when duly and validly completed, to be in
     recordable form and sufficient to effect the assignment of and transfer
     to the assignee thereof, under the Mortgage to which such assignment
     relates);

               (iv) the original recorded assignment or assignments of the
     Mortgage together with all interim recorded assignments of such Mortgage
     (noting the presence of a MIN in the case of each MERS Mortgage Loan);

               (v) the original or copies of each assumption, modification,
     written assurance or substitution agreement, if any; and

               (vi) the original or duplicate original lender's title policy

     all riders thereto shall be delivered within one year of the Closing
     Date.

          In addition, in connection with the assignment of any MERS Mortgage
Loan, the Seller agrees that it will cause, at the Seller's own expense, the
MERS(R) System to indicate (and provide evidence to the Trustee that it has
done so) that such Mortgage Loans have been

                                     -38-
<PAGE>

assigned by the Seller to the Trustee in accordance with this Agreement for
the benefit of the Certificateholders by including (or deleting, in the case
of Mortgage Loans which are repurchased in accordance with this Agreement) in
such computer files (a) the code "[IDENTIFY TRUSTEE SPECIFIC CODE]" in the
field "[IDENTIFY THE FIELD NAME FOR TRUSTEE]" which identifies the Trustee and
(b) the code "[IDENTIFY SERIES SPECIFIC CODE NUMBER]" in the field "Pool
Field" which identifies the series of the Certificates issued in connection
with such Mortgage Loans. The Seller further agrees that it will not, and will
not permit the Master Servicer to, and the Master Servicer agrees that it will
not, alter the codes referenced in this paragraph with respect to any Mortgage
Loan during the term of this Agreement unless and until such Mortgage Loan is
repurchased in accordance with the terms of this Agreement.

          In the event that in connection with any Mortgage Loan that is not a
MERS Mortgage Loan the Seller cannot deliver the original recorded Mortgage or
all interim recorded assignments of the Mortgage satisfying the requirements
of clause (ii), (iii) or (iv) concurrently with the execution and delivery
hereof, the Seller shall deliver or cause to be delivered to the Trustee a
true copy of such Mortgage and of each such undelivered interim assignment of
the Mortgage each certified by the Seller, the applicable title company,
escrow agent or attorney, or the originator of such Mortgage, as the case may
be, to be a true and complete copy of the original Mortgage or assignment of
Mortgage submitted for recording. For any such Mortgage Loan that is not a
MERS Mortgage Loan the Seller shall promptly deliver or cause to be delivered
to the Trustee such original Mortgage and such assignment or assignments with
evidence of recording indicated thereon upon receipt thereof from the public
recording official, or a copy thereof, certified, if appropriate, by the
relevant recording office, but in no event shall any such delivery be made
later than 270 days following the Closing Date; provided that in the event
that by such date the Seller is unable to deliver or cause to be delivered
each such Mortgage and each interim assignment by reason of the fact that any
such documents have not been returned by the appropriate recording office, or,
in the case of each interim assignment, because the related Mortgage has not
been returned by the appropriate recording office, the Seller shall deliver or
cause to be delivered such documents to the Trustee as promptly as possible
upon receipt thereof. If the public recording office in which a Mortgage or
interim assignment thereof is recorded retains the original of such Mortgage
or assignment, a copy of the original Mortgage or assignment so retained, with
evidence of recording thereon, certified to be true and complete by such
recording office, shall satisfy the Seller's obligations in Section 2.01. If
any document submitted for recording pursuant to this Agreement is (x) lost
prior to recording or rejected by the applicable recording office, the Seller
shall immediately prepare or cause to be prepared a substitute and submit it
for recording, and shall deliver copies and originals thereof in accordance
with the foregoing or (y) lost after recording, the Seller shall deliver to
the Trustee a copy of such document certified by the applicable public
recording office to be a true and complete copy of the original recorded
document. The Seller shall promptly forward or cause to be forwarded to the
Trustee (x) from time to time additional original documents evidencing an
assumption or modification of a Mortgage Loan and (y) any other documents
required to be delivered by the Depositor or the Master Servicer to the
Trustee within the time periods specified in this Section 2.01.

          With respect to each Mortgage Loan other than a MERS Mortgage Loan
as to which the related Mortgaged Property and Mortgage File are located in
(a) the State of California

                                     -39-
<PAGE>

or (b) any other jurisdiction under the laws of which the recordation of the
assignment specified in clause (iii) of the first paragraph of this Section
2.01(g) is not necessary to protect the Trustee's and the Certificateholders'
interest in the related Mortgage Loan, as evidenced by an Opinion of Counsel,
delivered by the Seller to the Trustee and a copy to the Rating Agencies, in
lieu of recording the assignment specified in clause (iii) of the first
paragraph of this Section 2.01(g), the Seller may deliver an unrecorded
assignment in blank, in form otherwise suitable for recording to the Trustee;
provided that if the related Mortgage has not been returned from the
applicable public recording office, such assignment, or any copy thereof, of
the Mortgage may exclude the information to be provided by the recording
office. As to any Mortgage Loan other than a MERS Mortgage Loan, the
procedures of the preceding sentence shall be applicable only so long as the
related Mortgage File is maintained in the possession of the Trustee in the
State or jurisdiction described in such sentence. In the event that with
respect to Mortgage Loans other than MERS Mortgage Loans (i) the Seller, the
Depositor or the Master Servicer gives written notice to the Trustee that
recording is required to protect the right, title and interest of the Trustee
on behalf of the Certificateholders in and to any Mortgage Loan, (ii) a court
recharacterizes the sale of the Mortgage Loans as a financing, or (iii) as a
result of any change in or amendment to the laws of the State or jurisdiction
described in the first sentence of this paragraph or any applicable political
subdivision thereof, or any change in official position regarding application
or interpretation of such laws, including a holding by a court of competent
jurisdiction, such recording is so required, the Trustee shall complete the
assignment in the manner specified in clause (iii) of the first paragraph of
this Section 2.01(g) and the Seller shall submit or cause to be submitted for
recording as specified above or, should the Seller fail to perform such
obligations, the Trustee shall cause the Master Servicer, at the Master
Servicer's expense, to cause each such previously unrecorded assignment to be
submitted for recording as specified above. In the event a Mortgage File is
released to the Master Servicer as a result of the Master Servicer's having
completed a Request for Release in the form of Exhibit M, the Trustee shall
complete the assignment of the related Mortgage in the manner specified in
clause (iii) of the first paragraph of this Section 2.01(g).

          So long as the Trustee maintains an office in the State of
California, the Trustee shall maintain possession of and not remove or attempt
to remove from the State of California any of the Mortgage Files as to which
the related Mortgaged Property is located in such State. In the event that the
Seller fails to record an assignment of a Mortgage Loan as herein provided
within 90 days of notice of an event set forth in clause (i), (ii) or (iii) of
the immediately preceding paragraph, the Master Servicer shall prepare and, if
required hereunder, file such assignments for recordation in the appropriate
real property or other records office. The Seller hereby appoints the Master
Servicer (and any successor servicer hereunder) as its attorney-in-fact with
full power and authority acting in its stead for the purpose of such
preparation, execution and filing.

          In the case of Mortgage Loans that become the subject of a Principal
Prepayment between the Closing Date and the Cut-off Date, the Seller shall
deposit or cause to be deposited in the Certificate Account the amount
required to be deposited therein with respect to such payment pursuant to
Section 3.05 hereof.

          Notwithstanding anything to the contrary in this Agreement, within
thirty days after the Closing Date, the Seller shall either (i) deliver to the
Trustee the Mortgage File as

                                     -40-
<PAGE>

required pursuant to this Section 2.01 for each Delay Delivery Mortgage Loan
or (ii) (A) repurchase the Delay Delivery Mortgage Loan or (B) substitute the
Delay Delivery Mortgage Loan for a Replacement Mortgage Loan, which repurchase
or substitution shall be accomplished in the manner and subject to the
conditions set forth in Section 2.03, provided that if the Seller fails to
deliver a Mortgage File for any Delay Delivery Mortgage Loan within the period
provided in the prior sentence, the cure period provided for in Section 2.02
or in Section 2.03 shall not apply to the initial delivery of the Mortgage
File for such Delay Delivery Mortgage Loan, but rather the Seller shall have
five (5) Business Days to cure such failure to deliver. The Seller shall
promptly provide each Rating Agency with written notice of any cure,
repurchase or substitution made pursuant to the proviso of the preceding
sentence. On or before the thirtieth (30th) day (or if such thirtieth day is
not a Business Day, the succeeding Business Day) after the Closing Date, the
Trustee shall, in accordance with the provisions of Section 2.02, send a Delay
Delivery Certification substantially in the form annexed hereto as Exhibit G-3
(with any applicable exceptions noted thereon) for all Delay Delivery Mortgage
Loans delivered within thirty (30) days after such date. The Trustee will
promptly send a copy of such Delay Delivery Certification to each Rating
Agency.

          Section 2.02 Acceptance by Trustee of the Mortgage Loans.

          The Trustee acknowledges receipt, subject to the limitations
contained in and any exceptions noted in the Initial Certification in the form
annexed hereto as Exhibit G-1 and in the list of exceptions attached thereto,
of the documents referred to in clauses (i) and (iii) of Section 2.01(g) above
with respect to the Mortgage Loans and all other assets included in the Trust
Fund and declares that it holds and will hold such documents and the other
documents delivered to it constituting the Mortgage Files, and that it holds
or will hold such other assets included in the Trust Fund, in trust for the
exclusive use and benefit of all present and future Certificateholders.

          The Trustee agrees to execute and deliver on the Closing Date to the
Depositor, the Master Servicer and the Seller an Initial Certification
substantially in the form annexed hereto as Exhibit G-1 to the effect that, as
to each Mortgage Loan listed in the Mortgage Loan Schedule (other than any
Mortgage Loan paid in full or any Mortgage Loan specifically identified in
such certification as not covered by such certification), the documents
described in Section 2.01(g)(i) and, in the case of each Mortgage Loan that is
not a MERS Mortgage Loan, the documents described in Section 2.01(g)(iii),
with respect to such Mortgage Loan as are in the Trustee's possession, and
based on its review and examination and only as to the foregoing documents,
such documents appear regular on their face and relate to such Mortgage Loan.
The Trustee agrees to execute and deliver within 30 days after the Closing
Date to the Depositor, the Master Servicer and the Seller an Interim
Certification substantially in the form annexed hereto as Exhibit G-2 to the
effect that, as to each Mortgage Loan listed in the Mortgage Loan Schedule
(other than any Mortgage Loan paid in full or any Mortgage Loan specifically
identified in such certification as not covered by such certification), all
documents required to be delivered to the Trustee pursuant to this Agreement
with respect to such Mortgage Loan are in its possession (except those
described in Section 2.01(g)(vi)) and based on its review and examination and

face and relate to such Mortgage Loan, and (ii) the information set forth in
items (ii), (iii), (iv), (v), (vi), (viii) and (xi) of the definition of the

                                     -41-

day is not a Business Day, the succeeding Business Day), the Trustee shall
deliver to the Depositor, the Master Servicer and the Seller a Delay Delivery
Certification with respect to the Mortgage Loans substantially in the form
annexed hereto as Exhibit G-3, with any applicable exceptions noted thereon.
The Trustee shall be under no duty or obligation to inspect, review or examine
such documents, instruments, certificates or other papers to determine that
the same are genuine, enforceable or appropriate for the represented purpose
or that they have actually been recorded in the real estate records or that
they are other than what they purport to be on their face.

          Not later than 180 days after the Closing Date, the Trustee shall
deliver to the Depositor, the Master Servicer and the Seller (and to any
Certificateholder that so requests) a Final Certification with respect to the
Mortgage Loans substantially in the form annexed hereto as Exhibit H, with any
applicable exceptions noted thereon.

          In connection with the Trustee's completion and delivery of such
Final Certification, the Trustee shall review each Mortgage File with respect
to the Mortgage Loans to determine that such Mortgage File contains the
documents identified in clauses (i) through (vi) of Section 2.01(g) with
respect to such Mortgage Loans.

          If, in the course of such review, the Trustee finds any document or
documents constituting a part of such Mortgage File that do not meet the
requirements of clauses (i) through (iv) and clause (vi) of Section 2.01(g),
the Trustee shall include such exceptions in such Final Certification (and the
Trustee shall state in such Final Certification whether any Mortgage File does
not then include the original or duplicate original lender's title policy or a
printout of the electronic equivalent and all riders thereto). If the public
recording office in which a Mortgage or assignment thereof is recorded retains
the original of such Mortgage or assignment, a copy of the original Mortgage
or assignment so retained, with evidence of recording thereon, certified to be
true and complete by such recording office, shall be deemed to satisfy the
requirements of clause (ii), (iii) or (iv) of Section 2.01(g), as applicable.
The Seller shall promptly correct or cure such defect referred to above within
90 days from the date it was so notified of such defect and, if the Seller
does not correct or cure such defect within such period, the Seller shall
either (A) if the time to cure such defect expires prior to the end of the
second anniversary of the Closing Date, substitute for the related Mortgage
Loan a Replacement Mortgage Loan, which substitution shall be accomplished in
the manner and subject to the conditions set forth in Section 2.03, or (B)
purchase such Mortgage Loan from the Trust Fund within 90 days from the date
the Seller was notified of such defect in writing at the Purchase Price of
such Mortgage Loan; provided that any such substitution pursuant to (A) above
or repurchase pursuant to (B) above shall not be effected prior to the
delivery to the Trustee of the Opinion of Counsel required by Section 2.05
hereof and any substitution pursuant to (A) above shall not be effected prior
to the additional delivery to the Trustee of a Request for File Release. No
substitution will be made in any calendar month after the Determination Date
for such month. The Purchase Price for any such Mortgage Loan shall be
deposited by the Seller in the Certificate Account and, upon receipt of such
deposit and Request for File Release with respect thereto, the Trustee shall
release the related Mortgage File to the Seller and shall execute and deliver
at the Seller's request such instruments of transfer or assignment as the
Seller has prepared, in each case without recourse, as shall be necessary to
vest in the Seller, or a designee, the Trustee's interest in any Mortgage Loan
released pursuant hereto. If pursuant to the foregoing provisions the Seller
repurchases a

substitute for or to purchase any Mortgage Loan that does not meet the
requirements described in the fifth paragraph of this Section 2.02 shall

the Depositor, the Co-Trustee and any Certificateholder against the Seller.

     a generally acceptable carrier that provides for fire and extended
     coverage and coverage for such other hazards as are customary in the area
     where the Mortgaged Property is located in an amount that is at least
     equal to the lesser of (i) the maximum insurable value of the
     improvements securing such Mortgage Loan or (ii) the greater of (a) the
     outstanding principal balance of the Mortgage Loan and (b) an amount such
     that the proceeds of such policy shall be sufficient to prevent the
     Mortgagor and/or the mortgagee from becoming a co-insurer. If the
     Mortgaged Property is a condominium unit, it is included under the
     coverage afforded by a blanket policy for the condominium unit. All such
     individual insurance policies and all flood policies referred to in item
     (xlvi) below contain a standard mortgagee clause naming the Seller or the
     original mortgagee, and its successors in interest, as mortgagee, and the
     Seller has received no notice that any premiums due and payable thereon
     have not been paid; the Mortgage obligates the Mortgagor thereunder to
     maintain all such insurance, including flood insurance, at the
     Mortgagor's cost and expense, and upon the Mortgagor's failure to do so,
     authorizes the holder of the Mortgage to obtain and maintain such
     insurance at the Mortgagor's cost and expense and to seek reimbursement
     therefor from the Mortgagor.

               (xlvi) If the Mortgaged Property is in an area identified in
     the Federal Register by the Federal Emergency Management Agency as having
     special flood hazards, a flood insurance policy in a form meeting the
     requirements of the current guidelines of the Flood Insurance
     Administration is in effect with respect to such Mortgaged Property with
     a generally acceptable carrier in an amount representing coverage not
     less than the least of (A) the original outstanding principal balance of
     the Mortgage Loan, (B) the minimum amount required to compensate for
     damage or loss on a replacement cost basis, or (C) the maximum amount of
     insurance that is available under the Flood Disaster Protection Act of
     1973, as amended.

               (xlvii) To the best of the Seller's knowledge, there is no
     proceeding occurring, pending or threatened for the total or partial
     condemnation of the Mortgaged Property.

               (xlviii) There is no material monetary default existing under
     any Mortgage or the related Mortgage Note and, to the best of the
     Seller's knowledge, there is no material event that, with the passage of
     time or with notice and the expiration of any grace or cure period, would
     constitute a default, breach, violation or event of acceleration under
     the Mortgage or the related Mortgage Note; and the Seller has not waived
     any default, breach, violation or event of acceleration.

               (xlix) Each Mortgaged Property is improved by a one- to
     four-family residential dwelling, including condominium units and
     dwelling units in PUDs. To the

                                     -50-
<PAGE>

     best of the Seller's knowledge, no improvement to a Mortgaged Property
     includes a cooperative or a mobile home or constitutes other than real
     property under state law.

               (l) Each Mortgage Loan is being serviced by the Master
     Servicer.

               (li) Any future advances made prior to the Cut-off Date have
     been consolidated with the outstanding principal amount secured by the
     Mortgage, and the secured principal amount, as consolidated, bears a
     single interest rate and single repayment term reflected on the Mortgage
     Loan Schedule. The consolidated principal amount does not exceed the
     original principal amount of the Mortgage Loan. The Mortgage Note does
     not permit or obligate the Master Servicer to make future advances to the
     Mortgagor at the option of the Mortgagor.

               (lii) All taxes, governmental assessments, insurance premiums,
     water, sewer and municipal charges, leasehold payments or ground rents
     that previously became due and owing have been paid, or an escrow of
     funds has been established in an amount sufficient to pay for every such
     item that remains unpaid and that has been assessed, but is not yet due
     and payable. Except for (A) payments in the nature of escrow payments,
     and (B) interest accruing from the date of the Mortgage Note or date of
     disbursement of the Mortgage proceeds, whichever is later, to the day
     that precedes by one month the Due Date of the first installment of
     principal and interest, including without limitation, taxes and insurance
     payments, the Master Servicer has not advanced funds, or induced,
     solicited or knowingly received any advance of funds by a party other
     than the Mortgagor, directly or indirectly, for the payment of any amount
     required by the Mortgage.

               (liii) The Mortgage Loans originated by the Seller were
     underwritten in all material respects in accordance with the Seller's
     underwriting guidelines for closed-end second lien mortgage loans or,
     with respect to Mortgage Loans purchased by the Seller, were underwritten
     in all material respects in accordance with customary and prudent
     underwriting guidelines generally used by originators of A quality
     mortgage loans.

               (liv) Prior to the approval of the Mortgage Loan application,
     an appraisal of the related Mortgaged Property was obtained from a
     qualified appraiser, duly appointed by the originator, who had no
     interest, direct or indirect, in the Mortgaged Property or in any loan
     made on the security thereof, and whose compensation is not affected by
     the approval or disapproval of the Mortgage Loan; such appraisal is in a
     form acceptable to Fannie Mae and Freddie Mac.

               (lv) None of the Mortgage Loans is a graduated payment mortgage
     loan or a growing equity mortgage loan, and no Mortgage Loan is subject
     to a buydown or similar arrangement.

               (lvi) The Mortgage Rates borne by the Mortgage Loans as of the
     Cut-off Date ranged from 5.000% per annum to 14.250% per annum and the
     weighted average Mortgage Rate as of the Cut-off Date was 7.815% per
     annum.

                                     -51-
<PAGE>

               (lvii) [Reserved]

               (lviii) The Mortgage Loans were selected from among outstanding
     one- to four-family mortgage loans in the Seller's portfolio at the
     Closing Date as to which the representations and warranties made as to
     the Mortgage Loans set forth in this Section 2.03(b) can be made. No
     selection was made in a manner that would adversely affect the interests
     of Certificateholders.

               (lix) [Reserved]

               (lx) Except for 226 Mortgage Loans representing approximately
     2.08% of the Mortgage Loans (by Stated Principal Balance as of the
     Cut-Off Date), each Mortgage Loan has a payment date on or before the Due
     Date in the month of the first Distribution Date.

               (lxi) The Mortgage Loans, individually and in the aggregate,
     conform in all material respects to the descriptions thereof in the
     Prospectus Supplement.

               (lxii) [Reserved]

               (lxiii) There is no obligation on the part of the Seller under
     the terms of the Mortgage or related Mortgage Note to make payments in
     addition to those made by the Mortgagor.

               (lxiv) Any leasehold estate securing a Mortgage Loan has a term
     of not less than five years in excess of the term of the related Mortgage
     Loan.

               (lxv) Each Mortgage Loan represents a "qualified mortgage"
     within the meaning of Section 860(a)(3) of the Code (but without regard
     to the rule in Treasury Regulation ss. 1.860G-2(f)(2) that treats a
     defective obligation as a qualified mortgage, or any substantially
     similar successor provision) and applicable Treasury regulations
     promulgated thereunder.

               (lxvi) No Mortgage Loan was either a "consumer credit contract"
     or a "purchase money loan" as such terms are defined in 16 C.F.R. Section
     433 nor is any Mortgage Loan a "mortgage" as defined in 15 U.S.C. ss.
     1602(aa).

               (lxvii) None of the Mortgage Loans were, or will be, 30 days or
     more delinquent in payment of the Scheduled Payment due on the first Due
     Date under such Mortgage Loan.

          (c) Upon discovery by any of the parties hereto of a breach of a
representation or warranty set forth in Section 2.03(a) or (b) that materially
and adversely affects the interests of the Certificateholders in any Mortgage
Loan, the party discovering such breach shall give prompt notice thereof to
the other parties. Each of the Master Servicer and the Seller (each, a
"Representing Party") hereby covenants with respect to the representations and
warranties set forth in Sections 2.03(a) and (b) that within 90 days of the
earlier of the discovery by such Representing Party or receipt of written
notice by such Representing Party from any party of a

                                     -52-
<PAGE>

breach of any representation or warranty set forth herein made that materially
and adversely affects the interests of the Certificateholders in any Mortgage
Loan, it shall cure such breach in all material respects and, if such breach
is not so cured, shall, (i) if such 90-day period expires prior to the second
anniversary of the Closing Date, remove such Mortgage Loan (a "Deleted
Mortgage Loan") from the Trust Fund and substitute in its place a Replacement
Mortgage Loan, in the manner and subject to the conditions set forth in this
Section; or (ii) repurchase the affected Mortgage Loan or Mortgage Loans from
the Trustee at the Purchase Price in the manner set forth below; provided that
any such substitution pursuant to (i) above or repurchase pursuant to (ii)
above shall not be effected prior to the delivery to the Trustee of the
Opinion of Counsel required by Section 2.05 hereof and any such substitution
pursuant to (i) above shall not be effected prior to the additional delivery
to the Trustee of a Request for Release substantially in the form of Exhibit
M. Any Representing Party liable for a breach under this Section 2.03 shall
promptly reimburse the Master Servicer and the Trustee for any expenses
reasonably incurred by the Master Servicer or the Trustee in respect of
enforcing the remedies for such breach. To enable the Master Servicer to amend
the Mortgage Loan Schedule, any Representing Party liable for a breach under
this Section 2.03 shall, unless it cures such breach in a timely fashion
pursuant to this Section 2.03, promptly notify the Master Servicer whether
such Representing Party intends either to repurchase, or to substitute for,
the Mortgage Loan affected by such breach. With respect to the representations
and warranties described in this Section that are made to the best of the
Representing Party's knowledge, if it is discovered by any of the Depositor,
the Master Servicer, the Seller or the Trustee that the substance of such
representation and warranty is inaccurate and such inaccuracy materially and
adversely affects the value of the related Mortgage Loan, notwithstanding the
Representing Party's lack of knowledge with respect to the substance of such
representation or warranty, such inaccuracy shall be deemed a breach of the
applicable representation or warranty.

          With respect to any Replacement Mortgage Loan or Loans, the Seller
delivering such Replacement Mortgage Loan shall deliver to the Trustee for the
benefit of the Certificateholders the related Mortgage Note, Mortgage and
assignment of the Mortgage, and such other documents and agreements as are
required by Section 2.01, with the Mortgage Note endorsed and the Mortgage
assigned as required by Section 2.01. No substitution will be made in any
calendar month after the Determination Date for such month. Scheduled Payments
due with respect to Replacement Mortgage Loans in the Due Period related to
the Distribution Date on which such proceeds are to be distributed shall not
be part of the Trust Fund and will be retained by the Seller delivering such
Replacement Loan on such Distribution Date. For the month of substitution,
distributions to Certificateholders will include the Scheduled Payment due on
any Deleted Mortgage Loan for the related Due Period and thereafter the Seller
shall be entitled to retain all amounts received in respect of such Deleted
Mortgage Loan. The Master Servicer shall amend the Mortgage Loan Schedule for
the benefit of the Certificateholders to reflect the removal of such Deleted
Mortgage Loan and the substitution of the Replacement Mortgage Loan or Loans
and the Master Servicer shall deliver the amended Mortgage Loan Schedule to
the Trustee. Upon such substitution, the Replacement Mortgage Loan or Loans
shall be subject to the terms of this Agreement in all respects, and the
Seller delivering such Replacement Mortgage Loan shall be deemed to have made
with respect to such Replacement Mortgage Loan or Loans, as of the date of
substitution, the representations and warranties set forth in Section 2.03(b)
with respect to such Mortgage Loan. Upon any such substitution and the deposit
to the Certificate Account of the amount required to be deposited therein in
connection

                                     -53-
<PAGE>

with such substitution as described in the following paragraph, the Trustee
shall release to the Representing Party the Mortgage File relating to such
Deleted Mortgage Loan and held for the benefit of the Certificateholders and
shall execute and deliver at the Master Servicer's direction such instruments
of transfer or assignment as have been prepared by the Master Servicer, in
each case without recourse, as shall be necessary to vest in the Seller, or
its respective designee, title to the Trustee's interest in any Deleted
Mortgage Loan substituted for pursuant to this Section 2.03.

          For any month in which the Seller substitutes one or more
Replacement Mortgage Loans for one or more Deleted Mortgage Loans, the Master
Servicer will determine the amount (if any) by which the aggregate principal
balance of all such Replacement Mortgage Loans as of the date of substitution
is less than the Stated Principal Balance (after application of the principal
portion of the Scheduled Payment due in the month of substitution) of all such
Deleted Mortgage Loans. An amount equal to the aggregate of the deficiencies
described in the preceding sentence (such amount, the "Substitution Adjustment
Amount") shall be forwarded by the Seller to the Master Servicer and deposited
by the Master Servicer into the Certificate Account not later than the
Determination Date for the Distribution Date relating to the Prepayment Period
during which the related Mortgage Loan became required to be purchased or
replaced hereunder.

          In the event that a Seller shall have repurchased a Mortgage Loan,
the Purchase Price therefor shall be deposited in the Certificate Account
pursuant to Section 3.08 on the Determination Date for the Distribution Date
in the month following the month during which such Seller became obligated to
repurchase or replace such Mortgage Loan and upon such deposit of the Purchase
Price, the delivery of the Opinion of Counsel required by Section 2.05, if
any, and the receipt of a Request for file Release, the Trustee shall release
the related Mortgage File held for the benefit of the Certificateholders to
such Seller, and the Trustee shall execute and deliver at such Person's
direction the related instruments of transfer or assignment prepared by such
Seller, in each case without recourse, as shall be necessary to transfer title
from the Trustee for the benefit of the Certificateholders and transfer the
Trustee's interest to such Seller to any Mortgage Loan purchased pursuant to
this Section 2.03. It is understood and agreed that the obligation under this
Agreement of the Seller to cure, repurchase or replace any Mortgage Loan as to
which a breach has occurred and is continuing shall constitute the sole remedy
against the Seller respecting such breach available to Certificateholders, the
Depositor, the Co-Trustee or the Trustee.

          (d) The representations and warranties set forth in Section 2.03
hereof shall survive delivery of the respective Mortgage Files to the Trustee
for the benefit of the Certificateholders.

          Section 2.04 Representations and Warranties of the Depositor.

          The Depositor hereby represents and warrants to the Master Servicer
and the Trustee as follows, as of the date hereof:

               (i) The Depositor is duly organized and is validly existing as
     a corporation in good standing under the laws of the State of Delaware
     and has full power and authority (corporate and other) necessary to own
     or hold its properties and to conduct

                                     -54-
<PAGE>

     its business as now conducted by it and to enter into and perform its
     obligations under this Agreement.

               (ii) The Depositor has the full corporate power and authority
     to execute, deliver and perform, and to enter into and consummate the
     transactions contemplated by, this Agreement and has duly authorized, by
     all necessary corporate action on its part, the execution, delivery and
     performance of this Agreement; and this Agreement, assuming the due
     authorization, execution and delivery hereof by the other parties hereto,
     constitutes a legal, valid and binding obligation of the Depositor,
     enforceable against the Depositor in accordance with its terms, subject,
     as to enforceability, to (i) bankruptcy, insolvency, reorganization,
     moratorium and other similar laws affecting creditors' rights generally
     and (ii) general principles of equity, regardless of whether enforcement
     is sought in a proceeding in equity or at law.

               (iii) The execution and delivery of this Agreement by the
     Depositor, the consummation of the transactions contemplated by this
     Agreement, and the fulfillment of or compliance with the terms hereof are
     in the ordinary course of business of the Depositor and will not (A)
     result in a material breach of any term or provision of the charter or
     by-laws of the Depositor or (B) materially conflict with, result in a
     material breach, violation or acceleration of, or result in a material
     default under, the terms of any other material agreement or instrument to
     which the Depositor is a party or by which it may be bound or (C)
     constitute a material violation of any statute, order or regulation
     applicable to the Depositor of any court, regulatory body, administrative
     agency or governmental body having jurisdiction over the Depositor; and
     the Depositor is not in breach or violation of any material indenture or
     other material agreement or instrument, or in violation of any statute,
     order or regulation of any court, regulatory body, administrative agency
     or governmental body having jurisdiction over it which breach or
     violation may materially impair the Depositor's ability to perform or
     meet any of its obligations under this Agreement.

               (iv) No litigation is pending, or, to the best of the
     Depositor's knowledge, threatened, against the Depositor that would
     materially and adversely affect the execution, delivery or enforceability
     of this Agreement or the ability of the Depositor to perform its
     obligations under this Agreement in accordance with the terms hereof.

               (v) No consent, approval, authorization or order of any court
     or governmental agency or body is required for the execution, delivery
     and performance by the Depositor of, or compliance by the Depositor with,
     this Agreement or the consummation of the transactions contemplated
     hereby, or if any such consent, approval, authorization or order is
     required, the Depositor has obtained the same.

          The Depositor hereby represents and warrants to the Trustee with
respect to each Mortgage Loan as of the Closing Date, and following the
transfer of the Mortgage Loans to it by the Seller, the Depositor had good
title to the Mortgage Loans, and the related Mortgage Notes were subject to no
offsets, claims, defenses or counterclaims.

                                     -55-
<PAGE>

          It is understood and agreed that the representations and warranties
set forth in the two immediately preceding paragraphs shall survive delivery
of the Mortgage Files to the Trustee. Upon discovery by the Depositor or the
Trustee of a breach of any of the foregoing representations and warranties set
forth in the immediately preceding paragraph (referred to herein as a
"breach"), which breach materially and adversely affects the interest of the
Certificateholders, the party discovering such breach shall give prompt
written notice to the others and to each Rating Agency. The Depositor hereby
covenants with respect to the representations and warranties made by it in
this Section 2.04 that within 90 days of the earlier of the discovery it or
receipt of written notice by it from any party of a breach of any
representation or warranty set forth herein made that materially and adversely
affects the interests of the Certificateholders in any Mortgage Loan, it shall
cure such breach in all material respects and, if such breach is not so cured,
shall repurchase or replace the affected Mortgage Loan or Loans in accordance
with the procedure set forth in Section 2.03(c).

          Section 2.05 Delivery of Opinion of Counsel in Connection with
                       Substitutions and Repurchases.

          (a) Notwithstanding any contrary provision of this Agreement, with
respect to any Mortgage Loan that is not in default or as to which default is
not imminent, no repurchase or substitution pursuant to Sections 2.02, 2.03 or
2.04 shall be made unless the Representing Party making such repurchase or
substitution delivers to the Trustee an Opinion of Counsel, addressed to the
Trustee, to the effect that such repurchase or substitution would not (i)
result in the imposition of the tax on "prohibited transactions" of the Trust
Fund or contributions after the Closing Date, as defined in sections
860F(a)(2) and 860G(d) of the Code, respectively or (ii) cause any REMIC
formed hereunder to fail to qualify as a REMIC at any time that any
Certificates are outstanding. Any Mortgage Loan as to which repurchase or
substitution was delayed pursuant to this paragraph shall be repurchased or
the substitution therefor shall occur (subject to compliance with Sections
2.02, 2.03 or 2.04) upon the earlier of (a) the occurrence of a default or
imminent default with respect to such loan and (b) receipt by the Trustee of
an Opinion of Counsel to the effect that such repurchase or substitution, as
applicable, will not result in the events described in clause (i) or clause
(ii) of the preceding sentence.

          (b) Upon discovery by the Depositor, the Seller, the Master Servicer
or the Trustee that any Mortgage Loan does not constitute a "qualified
mortgage" within the meaning of section 860G(a)(3) of the Code, the party
discovering such fact shall promptly (and in any event within 5 Business Days
of discovery) give written notice thereof to the other parties. In connection
therewith, the Trustee shall require the Seller, at the Seller's option, to
either (i) substitute, if the conditions in Section 2.03(b) with respect to
substitutions are satisfied, a Replacement Mortgage Loan for the affected
Mortgage Loan, or (ii) repurchase the affected Mortgage Loan within 90 days of
such discovery in the same manner as it would a Mortgage Loan for a breach of
representation or warranty contained in Section 2.03. The Trustee shall
reconvey to the Seller the Mortgage Loan to be released pursuant hereto in the
same manner, and on the same terms and conditions, as it would a Mortgage Loan
repurchased for breach of a representation or warranty contained in Section
2.03.

          Section 2.06 Authentication and Delivery of Certificates.

          The Trustee acknowledges the transfer and assignment to it of the
Trust Fund and, concurrently with such transfer and assignment, has executed,
authenticated and delivered, to or upon the order of the Depositor, the
Certificates in authorized denominations evidencing the entire ownership of
the Trust Fund. The Trustee agrees to hold the Trust Fund and exercise the
rights referred to above for the benefit of all present and future Holders of
the Certificates and to perform the duties set forth in this Agreement to the
best of its ability, to the end that the interests of the Holders of the
Certificates may be adequately and effectively protected.

          Section 2.07 Covenants of the Master Servicer.

          The Master Servicer hereby covenants to the Depositor and the
Trustee as follows:

          (a) the Master Servicer shall comply in the performance of its
obligations under this Agreement with all reasonable rules and requirements of
the insurer under each Required Insurance Policy; and

          (b) no written information, certificate of an officer, statement
furnished in writing or written report delivered to the Depositor, any
affiliate of the Depositor or the Trustee and prepared by the Master Servicer
pursuant to this Agreement will contain any untrue statement of a material
fact or omit to state a material fact necessary to make the information,
certificate, statement or report not misleading.

          Section 2.08 Seller Loss Coverage Obligation.

          The Seller hereby agrees that, for the benefit of the
Certificateholders, on the Business Day immediately preceding each
Distribution Date it will remit to the Trustee for deposit into the
Distribution Account the amount of any Enhancement Payment due for such
Distribution Date as specified in the remittance report delivered by the
Master Servicer. The obligation of the Seller to remit Enhancement Payments
will terminate when the Seller Loss Coverage Amount has been reduced to zero.

                                 ARTICLE III.

                ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

          Section 3.01 Master Servicer to Service Mortgage Loans.

          For and on behalf of the Certificateholders, the Master Servicer
shall service and administer the Mortgage Loans in accordance with customary
and usual standards of practice of prudent mortgage loan lenders in the
respective states in which the Mortgaged Properties are located, including
taking all required and appropriate actions under each Required Insurance
Policy. In connection with such servicing and administration, the Master
Servicer shall have full power and authority, acting alone and/or through
subservicers as provided in Section 3.02 hereof, subject to the terms hereof
(i) to execute and deliver, on behalf of the Certificateholders and the
Trustee, customary consents or waivers and other instruments and documents,
(ii) to consent to transfers of any Mortgaged Property and assumptions of the
Mortgage Notes and related Mortgages (but only in the manner provided in this
Agreement), (iii) to collect any Insurance Proceeds, other Liquidation
Proceeds (other than proceeds of the Loan Insurance Policy) and, Subsequent
Recoveries, and (iv) subject to Section 3.12(b), to effectuate foreclosure or
other conversion of the ownership of the Mortgaged Property securing any
Mortgage Loan; provided that the Master Servicer shall take no action that is
inconsistent with or prejudices the interests of the Trustee or the
Certificateholders in any Mortgage Loan or the rights and interests of the
Depositor and the Trustee under this Agreement. The Master Servicer shall
represent and protect the interest of the Trustee in the same manner as it
currently protects its own interest in mortgage loans in its own portfolio in
any claim, proceeding or litigation regarding a Mortgage Loan and shall not
make or permit any modification, waiver or amendment of any term of any
Mortgage Loan which would (i) cause any REMIC formed hereunder to fail to
qualify as a REMIC or (ii) result in the imposition of any tax under Section
860(a) or 860(d) of the Code, but in any case the Master Servicer shall not
act in any manner that is a lesser standard than that provided in the first
sentence of this Section 3.01. Without limiting the generality of the
foregoing, the Master Servicer, in its own name or in the name of the
Depositor and the Trustee, is hereby authorized and empowered by the Depositor
and the Trustee, when the Master Servicer believes it appropriate in its
reasonable judgment, to execute and deliver, on behalf of the Trustee, the
Depositor, the Certificateholders or any of them, any and all instruments of
satisfaction or cancellation, or of partial or full release or discharge and
all other comparable instruments, with respect to the Mortgage Loans, and with
respect to the Mortgaged Properties held for the benefit of the
Certificateholders. The Master Servicer shall prepare and deliver to the
Depositor and/or the Trustee such documents requiring execution and delivery
by any or all of them as are necessary or appropriate to enable the Master
Servicer to service and administer the Mortgage Loans. Upon receipt of such
documents, the Depositor and/or the Trustee shall execute such documents and
deliver them to the Master Servicer. The Master Servicer further is authorized
and empowered by the Trustee, on behalf of the Certificateholders and the
Trustee, in its own name or in the name of the Subservicer, when the Master
Servicer or the Subservicer, as the case may be, believes it appropriate in
its best judgment to register any Mortgage Loan on the MERS(R) System, or
cause the removal from the registration of any Mortgage Loan on the MERS(R)
System, to execute and deliver, on behalf of the Trustee and the
Certificateholders or any of them, any and all instruments of assignment and
other comparable instruments with

                                     -58-
<PAGE>

respect to such assignment or re-recording of a Mortgage in the name of MERS,
solely as nominee for the Trustee and its successors and assigns.

          In accordance with the standards of the preceding paragraph, the
Master Servicer shall advance or cause to be advanced funds as necessary for
the purpose of effecting the payment of taxes and assessments on the Mortgaged
Properties, which advances shall be reimbursable in the first instance from
related collections from the Mortgagors pursuant to Section 3.06, and further
as provided in Section 3.08. All costs incurred by the Master Servicer, if
any, in effecting the timely payments of taxes and assessments on the
Mortgaged Properties and related insurance premiums shall not, for the purpose
of calculating monthly distributions to the Certificateholders, be added to
the Stated Principal Balance under the related Mortgage Loans, notwithstanding
that the terms of such Mortgage Loans so permit.

          The Master Servicer shall deliver a list of Servicing Officers to
the Trustee by the Closing Date.

          In connection with its activities as Master Servicer of the Mortgage
Loans, the Master Servicer agrees to present, on behalf of itself, the Trustee
and the Certificateholders, claims to the insurer under any primary insurance
policies and, in this regard, to take any reasonable action necessary to
permit recovery under any primary insurance policies respecting defaulted
Mortgage Loans. Any amounts collected by the Master Servicer under any primary
insurance policies shall be deposited in the Certificate Account.

          In the event that a shortfall in any collection on or liability with
respect to any Mortgage Loan results from or is attributable to adjustments to
Mortgage Rates, Scheduled Payments or Stated Principal Balances that were made
by the Master Servicer in a manner not consistent with the terms of the
related Mortgage Note and this Agreement, the Master Servicer, upon discovery
or receipt of notice thereof, immediately shall deliver to the Trustee for
deposit in the Distribution Account from its own funds the amount of any such
shortfall and shall indemnify and hold harmless the Trust Fund, the Trustee,
the Co-Trustee, the Depositor and any successor master servicer in respect of
any such liability. Such indemnities shall survive the termination or
discharge of this Agreement. Notwithstanding the foregoing, this Section 3.01
shall not limit the ability of the Master Servicer to seek recovery of any
such amounts from the related Mortgagor under the terms of the related
Mortgage Note, as permitted by law and shall not be an expense of the Trust.

          Section 3.02 Subservicing; Enforcement of the Obligations of Master
                       Servicer.

          (a) The Master Servicer may arrange for the subservicing of any
Mortgage Loan by a subservicer (each, a "Subservicer") pursuant to a
subservicing agreement (each, a "Subservicing Agreement"); provided that (i)
such subservicing arrangement and the terms of the related subservicing
agreement must provide for the servicing of such Mortgage Loans in a manner
consistent with the servicing arrangements contemplated hereunder and (ii)
such subservicing agreements would not result in a withdrawal or a downgrading
by any Rating Agency of the ratings on any Class of Certificates, as evidenced
by a letter to that effect delivered by each Rating Agency to the Depositor.
The Master Servicer shall deliver to the Trustee copies of all Sub-servicing
Agreements, and any amendments or modifications thereof,

                                     -59-
<PAGE>

promptly upon the Master Servicer's execution and delivery of such
instruments. The Master Servicer shall be entitled to terminate any
Subservicing Agreement and the rights and obligations of any Subservicer
pursuant to any Subservicing Agreement in accordance with the terms and
conditions of such Subservicing Agreement. Notwithstanding the provisions of
any subservicing agreement, any of the provisions of this Agreement relating
to agreements or arrangements between the Master Servicer or a subservicer or
reference to actions taken through a Master Servicer or otherwise, the Master
Servicer shall remain obligated and liable to the Depositor, the Trustee and
the Certificateholders for the servicing and administration of the Mortgage
Loans in accordance with the provisions of this Agreement without diminution
of such obligation or liability by virtue of such subservicing agreements or
arrangements or by virtue of indemnification from the subservicer and to the
same extent and under the same terms and conditions as if the Master Servicer
alone were servicing and administering the Mortgage Loans. Every subservicing
agreement entered into by the Master Servicer shall contain a provision giving
the successor Master Servicer the option to terminate such agreement in the
event a successor Master Servicer is appointed. All actions of each
subservicer performed pursuant to the related subservicing agreement shall be
performed as an agent of the Master Servicer with the same force and effect as
if performed directly by the Master Servicer.

          (b) For purposes of this Agreement, the Master Servicer shall be
deemed to have received any collections, recoveries or payments with respect
to the Mortgage Loans that are received by a subservicer regardless of whether
such payments are remitted by the subservicer to the Master Servicer.

          Section 3.03 Rights of the Depositor, the Seller, the
                       Certificateholders and the Trustee in Respect
                       of the Master Servicer.

          None of the Trustee, the Co-Trustee, the Seller, the
Certificateholders or the Depositor shall have any responsibility or liability
for any action or failure to act by the Master Servicer, and none of them is
obligated to supervise the performance of the Master Servicer hereunder or
otherwise. The Master Servicer shall afford (and any Subservicing Agreement
shall provide that each Subservicer shall afford) the Depositor and the
Trustee, upon reasonable notice, during normal business hours, access to all
records maintained by the Master Servicer (and any such Subservicer) in
respect of the Master Servicer's rights and obligations hereunder and access
to officers of the Master Servicer (and those of any such Subservicer)
responsible for such obligations. Upon request, the Master Servicer shall
furnish to the Depositor and the Trustee its (and any such Subservicer's) most
recent financial statements and such other information relating to the Master
Servicer's capacity to perform its obligations under this Agreement that it
possesses. To the extent such information is not otherwise available to the
public, the Depositor and the Trustee shall not disseminate any information
obtained pursuant to the preceding two sentences without the Masters
Servicer's (or any such Subservicer's) written consent, except as required
pursuant to this Agreement or to the extent that it is necessary to do so (i)
in working with legal counsel, auditors, taxing authorities or other
governmental agencies, rating agencies or reinsurers or (ii) pursuant to any
law, rule, regulation, order, judgment, writ, injunction or decree of any
court or governmental authority having jurisdiction over the Depositor, the
Trustee or the Trust Fund, and in either case, the Depositor or the Trustee,
as the case may be, shall use its reasonable best efforts to assure the
confidentiality of any such disseminated non-public information. The Depositor
may, but is not obligated to, enforce the

                                     -60-
<PAGE>

obligations of the Master Servicer under this Agreement and may, but is not
obligated to, perform, or cause a designee to perform, any defaulted
obligation of the Master Servicer under this Agreement or exercise the rights
of the Master Servicer under this Agreement; provided by virtue of such
performance by the Depositor of its designee. The Depositor shall not have any
responsibility or liability for any action or failure to act by the Master
Servicer and is not obligated to supervise the performance of the Master
Servicer under this Agreement or otherwise.

          Section 3.04 Trustee to Act as Master Servicer.

          In the event that the Master Servicer shall for any reason no longer
be the Master Servicer hereunder (including by reason of an Event of Default),
the Trustee or its designee shall thereupon assume all of the rights and
obligations of the Master Servicer hereunder arising thereafter (except that
the Trustee shall not be (i) liable for losses of the Master Servicer pursuant
to Section 3.10 hereof or any acts or omissions of the predecessor Master
Servicer hereunder, (ii) obligated to make Advances if it is prohibited from
doing so by applicable law, (iii) obligated to effectuate repurchases or
substitutions of Mortgage Loans hereunder, including pursuant to Section 2.02
or 2.03 hereof, (iv) responsible for expenses of the Master Servicer pursuant
to Section 2.03 or (v) deemed to have made any representations and warranties
hereunder, including pursuant to Section 2.03 or the first paragraph of
Section 6.02 hereof). If the Master Servicer shall for any reason no longer be
the Master Servicer (including by reason of any Event of Default), the Trustee
(or any other successor servicer) may, at its option, succeed to any rights
and obligations of the Master Servicer under any subservicing agreement in
accordance with the terms thereof; provided that the Trustee (or any other
successor servicer) shall not incur any liability or have any obligations in
its capacity as servicer under a subservicing agreement arising prior to the
date of such succession unless it expressly elects to succeed to the rights
and obligations of the Master Servicer thereunder; and the Master Servicer
shall not thereby be relieved of any liability or obligations under the
subservicing agreement arising prior to the date of such succession.

          The Master Servicer shall, upon request of the Trustee, but at the
expense of the Master Servicer, deliver to the assuming party all documents
and records relating to each subservicing agreement and the Mortgage Loans
then being serviced thereunder and an accounting of amounts collected held by
it and otherwise use its best efforts to effect the orderly and efficient
transfer of the subservicing agreement to the assuming party.

          Section 3.05 Collection of Mortgage Loan Payments; Certificate
                       Account; Distribution Account; Seller Shortfall
                       Interest Requirement.

          (a) The Master Servicer shall make reasonable efforts in accordance
with customary and usual standards of practice of prudent mortgage lenders in
the respective states in which the Mortgaged Properties are located to collect
all payments called for under the terms and provisions of the Mortgage Loans
to the extent such procedures shall be consistent with this Agreement and the
terms and provisions of any related Required Insurance Policy. Consistent with
the foregoing, the Master Servicer may in its discretion (i) waive any late
payment charge or, subject to Section 3.20, any Prepayment Charge or penalty
interest in connection with the prepayment of a Mortgage Loan and (ii) extend
the due dates for payments due on a Mortgage

                                     -61-
<PAGE>

Note for a period not greater than 270 days. In the event of any such
arrangement, the Master Servicer shall make Advances on the related Mortgage
Loan during the scheduled period in accordance with the amortization schedule
of such Mortgage Loan without modification thereof by reason of such
arrangements. The Master Servicer shall not be required to institute or join
in litigation with respect to collection of any payment (whether under a
Mortgage, Mortgage Note or otherwise or against any public or governmental
authority with respect to a taking or condemnation) if it reasonably believes
that enforcing the provision of the Mortgage or other instrument pursuant to
which such payment is required is prohibited by applicable law.

          (b) The Master Servicer shall establish and maintain a Certificate
Account into which the Master Servicer shall deposit or cause to be deposited
on a daily basis within two Business Days of receipt, except as otherwise
specifically provided herein, the following payments and collections remitted
by Subservicers or received by it in respect of Mortgage Loans subsequent to
the Cut-off Date (other than in respect of principal and interest due on the
Mortgage Loans before the Cut-off Date) and the following amounts (without
duplication) required to be deposited hereunder:

               (i) all payments on account of principal, including Principal
     Prepayments, on the Mortgage Loans;

               (ii) all payments on account of interest on the Mortgage Loans
     net of the related Servicing Fee permitted under Section 3.15, other than
     interest accrued on the Mortgage Loans prior to the Cut-off Date, and the
     Certificate Account Deposit;

               (iii) all Insurance Proceeds (other than proceeds of the Loan
     Insurance Policy);

               (iv) all other Liquidation Proceeds and Subsequent Recoveries,
     other than proceeds to be applied to the restoration or repair of the
     Mortgaged Property or released to the Mortgagor in accordance with the
     Master Servicer's normal servicing procedures;

               (v) all Compensating Interest;

               (vi) any amount required to be deposited by the Master Servicer
     pursuant to Section 3.05(e) in connection with any losses on Permitted
     Investments;

               (vii) any amounts required to be deposited by the Master
     Servicer pursuant to Section 3.10 hereof;

               (viii) the Purchase Price and any Substitution Adjustment
     Amount;

               (ix) all Advances made by the Master Servicer pursuant to
     Section 4.01;

               (x) all Prepayment Charges paid by a Mortgagor in connection
     with the full or partial Principal Prepayment of the related Mortgage
     Loan; and

               (xi) any other amounts required to be deposited hereunder.

                                     -62-
<PAGE>

          The foregoing requirements for remittance by the Master Servicer
into the Certificate Account shall be exclusive, it being understood and
agreed that, without limiting the generality of the foregoing, payments in the
nature of prepayment penalties, late payment charges or assumption fees, if
collected, need not be remitted by the Master Servicer. In the event that the
Master Servicer shall remit any amount not required to be remitted and not
otherwise subject to withdrawal pursuant to Section 3.08 hereof, it may at any
time withdraw or direct the institution maintaining the Certificate Account,
to withdraw such amount from the Certificate Account, any provision herein to
the contrary notwithstanding. Such withdrawal or direction may be accomplished
by delivering written notice thereof to the institution maintaining the
Certificate Account, that describes the amounts deposited in error in the
Certificate Account. The Master Servicer shall maintain adequate records with
respect to all withdrawals made pursuant to this Section. All funds deposited
in the Certificate Account shall be held in trust for the Certificateholders
until withdrawn in accordance with Section 3.08.

          No later than 1:00 p.m. Pacific time on the Business Day prior to
the Master Servicer Advance Date in January 2005, the Seller shall remit to
the Master Servicer, and the Master Servicer shall deposit in the Certificate
Account, the Seller Shortfall Interest Requirement (if any) for such Master
Servicer Advance Date.

          (c) The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Distribution Account. The Trustee shall, promptly upon
receipt, deposit in the Distribution Account and retain therein the following:

               (i) the aggregate amount remitted by the Master Servicer
     pursuant to the second paragraph of Section 3.08(a);

               (ii) any Enhancement Payment made by the Seller;

               (iii) any amount required to be deposited by the Master
     Servicer pursuant to Section 3.05(e) in connection with any losses on
     Permitted Investments; and

               (iv) any proceeds paid in respect of the Mortgage Loans
     pursuant to the Loan Insurance Policy.

          The foregoing requirements for remittance by the Master Servicer and
deposit by the Trustee into the Distribution Account shall be exclusive. In
the event that the Master Servicer shall remit any amount not required to be
remitted and not otherwise subject to withdrawal pursuant to Section 3.08
hereof, it may at any time direct the Trustee to withdraw such amount from the
Distribution Account, any provision herein to the contrary notwithstanding.
Such direction may be accomplished by delivering a written notice to the
Trustee that describes the amounts deposited in error in the Distribution
Account. All funds deposited in the Distribution Account shall be held by the
Trustee in trust for the Certificateholders until disbursed in accordance with
this Agreement or withdrawn in accordance with Section 3.08. In no event shall
the Trustee incur liability for withdrawals from the Distribution Account at
the direction of the Master Servicer.

          (d) [Reserved].

          (e) Each institution that maintains the Certificate Account or the
Distribution Account shall invest the funds in each such account, as directed
by the Master Servicer, in Permitted Investments, which shall mature not later
than (x) in the case of the Certificate Account, the second Business Day next
preceding the related Distribution Account Deposit Date (except that if such
Permitted Investment is an obligation of the institution that maintains such
Certificate Account, then such Permitted Investment shall mature not later
than the Business Day next preceding such Distribution Account Deposit Date)
and (y) in the case of the Distribution Account and the Carryover Reserve Fund
the Business Day immediately preceding the first Distribution Date that
follows the date of such investment (except that if such Permitted Investment
is an obligation of the institution that maintains such Distribution Account
or the Carryover Reserve Fund, then such Permitted Investment shall mature not
later than such Distribution Date), in each case, shall not be sold or
disposed of prior to its maturity. All such Permitted Investments shall be
made in the name of the Trustee, for the benefit of the Certificateholders,
except in connection with Permitted Investments made with respect to funds in
the Carryover Reserve Fund which shall be made in the name of the Trustee, for
the benefit of the Certificateholders. In the case of (i) the Certificate
Account and the Distribution Account, all income and gain net of any losses
realized from any such investment shall be for the benefit of the Master
Servicer as servicing compensation and shall be remitted to it monthly as
provided herein, and (ii) the Carryover Reserve Fund, all income and gain net
of any losses realized from any such investment shall be for the benefit of
the Class A-IO Certificateholders and shall be remitted to the Class A-IO
Certificateholders monthly as provided herein. The amount of any losses
incurred in the Certificate Account or the Distribution Account in respect of
any such investments shall be deposited by the Master Servicer in the
Certificate Account or paid to the Trustee for deposit into the Distribution
Account out of the Master Servicer's own funds immediately as realized. Any
losses incurred in the Carryover Reserve Fund in respect of any such
investments shall be charged against amounts on deposit in the Carryover
Reserve Fund (or such investments) immediately as realized. The Trustee shall
not be liable for the amount of any loss incurred in respect of any investment
or lack of investment of funds held in the Certificate Account, the
Distribution Account or the Carryover Reserve Fund and made in accordance with
this Section 3.05.

          (f) The Master Servicer shall give at least 30 days advance notice
to the Trustee, the Seller, each Rating Agency and the Depositor of any
proposed change of location of the Certificate Account prior to any change
thereof. The Trustee shall give at least 30 days advance notice to the Master
Servicer, the Seller, each Rating Agency and the Depositor of any proposed
change of the location of the Distribution Account or the Carryover Reserve
Fund prior to any change thereof.

          (g) Except as otherwise expressly provided in this Agreement, if any
default occurs under any Permitted Investment, the Trustee may and, subject to
Section 8.01 and 8.02(4), at the request of the Holders of Certificates
representing more than 50% of the Voting Rights, shall take any action
appropriate to enforce payment or performance, including the institution and
prosecution of appropriate proceedings.

          Section 3.06 Collection of Taxes, Assessments and Similar Items;
                       Escrow Accounts.

          To the extent required by the related Mortgage Note, the Master
Servicer shall establish and maintain one or more accounts (each, an "Escrow
Account") and deposit and retain therein all collections from the Mortgagors
(or advances by the Master Servicer) for the payment of taxes, assessments,
hazard insurance premiums or comparable items for the account of the
Mortgagors. Nothing herein shall require the Master Servicer to compel a
Mortgagor to establish an Escrow Account in violation of applicable law.

          Withdrawals of amounts so collected from the Escrow Accounts may be
made only to effect timely payment of taxes, assessments, hazard insurance
premiums, condominium or PUD association dues, or comparable items, to
reimburse the Master Servicer out of related collections for any payments made
pursuant to Sections 3.01 hereof (with respect to taxes and assessments and
insurance premiums) and 3.10 hereof (with respect to hazard insurance), to
refund to any Mortgagors any sums as may be determined to be overages, to pay
interest, if required by law or the terms of the related Mortgage or Mortgage
Note, to Mortgagors on balances in the Escrow Account or to clear and
terminate the Escrow Account at the termination of this Agreement in
accordance with Section 9.01 hereof. The Escrow Accounts shall not be a part
of the Trust Fund.

          Section 3.07 Access to Certain Documentation and Information
                       Regarding the Mortgage Loans.

          The Master Servicer shall afford the Depositor and the Trustee
reasonable access to all records and documentation regarding the Mortgage
Loans and all accounts, insurance policies and other matters relating to this
Agreement, such access being afforded without charge, but only upon reasonable
request and during normal business hours at the offices of the Master Servicer
designated by it.

          Upon reasonable advance notice in writing if required by federal
regulation, the Master Servicer will provide to each Certificateholder or
Certificate Owner that is a savings and loan association, bank or insurance
company certain reports and reasonable access to information and documentation
regarding the Mortgage Loans sufficient to permit such Certificateholder or
Certificate Owner to comply with applicable regulations of the OTS or other
regulatory authorities with respect to investment in the Certificates;
provided that the Master Servicer shall be entitled to be reimbursed by each
such Certificateholder or Certificate Owner for actual expenses incurred by
the Master Servicer in providing such reports and access.

          Section 3.08 Permitted Withdrawals from the Certificate Account,
                       Distribution Account, the Carryover Reserve Fund and
                       the Principal Reserve Fund.

          (a) The Master Servicer may from time to time make withdrawals from
the Certificate Account for the following purposes:

               (i) to pay to the Master Servicer (to the extent not previously
     paid to or withheld by the Master Servicer), as servicing compensation in
     accordance with Section

                                     -65-
<PAGE>

     3.15, that portion of any payment of interest that equals the Servicing
     Fee for the period with respect to which such interest payment was made,
     and, as additional servicing compensation to the Master Servicer, those
     other amounts set forth in Section 3.15;

               (ii) to reimburse each of the Master Servicer and the Trustee
     for Advances made by it with respect to the Mortgage Loans, such right of
     reimbursement pursuant to this subclause (ii) being limited to amounts
     received on particular Mortgage Loan(s) (including, for this purpose,
     Liquidation Proceeds, Insurance Proceeds and Subsequent Recoveries (other
     than, in each case, proceeds of the Loan Insurance Policy)) that
     represent late recoveries of payments of principal and/or interest on
     such particular Mortgage Loan(s) in respect of which any such Advance was
     made;

               (iii) to pay the Co-Trustee, for payment to the Loan Insurance
     Policy Provider as provided below, the Loan Insurance Policy Premium and
     any other amounts payable to the Loan Insurance Policy Provider under the
     Loan Insurance Policy;

               (iv) to reimburse each of the Master Servicer and the Trustee
     for any Nonrecoverable Advance previously made;

               (v) to reimburse the Master Servicer from Insurance Proceeds
     (other than proceeds of the Loan Insurance Policy) for Insured Expenses
     incurred by the Master Servicer and covered by the related Insurance
     Policy;

               (vi) to pay the Master Servicer any unpaid Servicing Fees and
     to reimburse it for any unreimbursed Servicing Advances, the Master
     Servicer's right to reimbursement of Servicing Advances pursuant to this
     subclause (vi) with respect to any Mortgage Loan being limited to amounts
     received on particular Mortgage Loan(s) (including, for this purpose,
     Liquidation Proceeds, Insurance Proceeds and Subsequent Recoveries and
     purchase and repurchase proceeds) that represent late recoveries of the
     payments for which such advances were made pursuant to Section 3.01 or
     Section 3.06;

               (vii) to pay to the Seller, the Depositor or the Master
     Servicer, as applicable, with respect to each Mortgage Loan or property
     acquired in respect thereof that has been purchased pursuant to Section
     2.02, 2.03, 2.04 or 3.12, all amounts received thereon and not taken into
     account in determining the related Stated Principal Balance of such
     purchased Mortgage Loan;

               (viii) to reimburse the Seller, the Master Servicer or the
     Depositor for expenses incurred by any of them in connection with the
     Mortgage Loans or Certificates and reimbursable pursuant to Section 6.03
     hereof provided that such amount shall only be withdrawn following the
     withdrawal from the Certificate Account for deposit into the Distribution
     Account pursuant to the following paragraph;

               (ix) to withdraw any amount deposited in the Certificate
     Account and not required to be deposited therein; and

               (x) to clear and terminate the Certificate Account upon
     termination of this Agreement pursuant to Section 9.01 hereof.

                                     -66-
<PAGE>

          In addition, no later than 1:00 p.m. Pacific time on the
Distribution Account Deposit Date, the Master Servicer shall withdraw from the
Certificate Account and remit to the Trustee the Interest Remittance Amount
and the Principal Remittance Amount for such Distribution Date to the extent
on deposit in the Certificate Account, and the Trustee shall deposit such
amount in the Distribution Account.

          The Trustee shall establish and maintain, on behalf of the
Certificateholders, a Principal Reserve Fund in the name of the Trustee. On
the Closing Date, the Seller shall deposit into the Principal Reserve Fund
$1,732.42. Funds on deposit in the Principal Reserve Fund shall not be
invested. The Principal Reserve Fund shall be treated as an "outside reserve
fund" under applicable Treasury regulations and shall not be part of any REMIC
created under this Agreement. Amounts on deposit in the Principal Reserve Fund
shall not be invested.

          On the Business Day before the Distribution Date occurring in
January 2005, the Trustee shall transfer from the Principal Reserve Fund to
the Distribution Account $1,632.42 and shall distribute such amount to the
Certificates on the Distribution Date pursuant to Section 4.04(d).

          On the Business Day before the Class P Principal Distribution Date,
the Trustee shall transfer from the Principal Reserve Fund to the Distribution
Account $100.00 and shall distribute such amount to the Class P Certificates
on the Class P Principal Distribution Date. The Trustee shall then terminate
the Principal Reserve Fund.

          The Master Servicer shall keep and maintain separate accounting, on
a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Certificate Account pursuant to subclauses (i), (ii),
(iv), (v), (vi), (vii) and (viii) above. Prior to making any withdrawal from
the Certificate Account pursuant to subclause (iv), the Master Servicer shall
deliver to the Trustee an Officer's Certificate of a Servicing Officer
indicating the amount of any previous Advance determined by the Master
Servicer to be a Nonrecoverable Advance and identifying the related Mortgage
Loan(s), and their respective portions of such Nonrecoverable Advance.

          (b) The Trustee shall withdraw funds from the Distribution Account
for distribution to the Certificateholders in the manner specified in this
Agreement (and shall withhold, from the amounts so withdrawn, the amount of
any taxes that it is authorized to retain pursuant to Section 8.11(c)). In
addition, the Trustee may from time to time make withdrawals from the
Distribution Account for the following purposes:

               (i) to pay the Trustee the Trustee Fee on each Distribution
     Date;

               (ii) to pay to the Master Servicer, as additional servicing
     compensation, earnings on or investment income with respect to funds in
     or credited to the Distribution Account;

               (iii) to withdraw any amount deposited in the Distribution
     Account and not required to be deposited therein;

                                     -67-

               (iv) to reimburse the Trustee for any unreimbursed Advances
     made by it pursuant to Section 4.01(d) hereof, such right of
     reimbursement pursuant to this subclause (iv) being limited to (x)
     amounts received on the related Mortgage Loan(s) in respect of which any
     such Advance was made and (y) amounts not otherwise reimbursed to the
     Trustee pursuant to Section 3.08(a)(ii) hereof;

               (v) to reimburse the Trustee for any Nonrecoverable Advance
     previously made by the Trustee pursuant to Section 4.01(d) hereof, such
     right of reimbursement pursuant to this subclause (v) being limited to
     amounts not otherwise reimbursed to the Trustee pursuant to Section
     3.08(a)(iv) hereof; and

               (vi) to clear and terminate the Distribution Account upon
     termination of this Agreement pursuant to Section 9.01 hereof.

          (c) The Trustee shall withdraw funds from the Carryover Reserve Fund
for distribution to the Certificateholders in the manner specified in this
Agreement (and shall withhold, from the amounts so withdrawn, the amount of
any taxes that it is authorized to retain pursuant to Section 8.11(c)). In
addition, the Trustee may from time to time make withdrawals from the
Carryover Reserve Fund for the following purposes:

               (i) to withdraw any amount deposited in the Carryover Reserve
     Fund and not required to be deposited therein; and

               (ii) to clear and terminate the Carryover Reserve Fund upon
     termination of this Agreement pursuant to Section 9.01 hereof.]

          Section 3.09 The Loan Insurance Policy.

          The Master Servicer shall take whatever action is appropriate to
maximize the amounts payable under the Loan Insurance Policy and to service
the Mortgage Loans in the manner required by the Loan Insurance Policy. The
Master Servicer shall prepare and submit all claims eligible for submission
under the Loan Insurance Policy and shall perform all of the obligations of
the insured under the Loan Insurance Policy other than those in Section 8.12
hereof to be performed by the Co-Trustee. If the Loan Insurance Policy is
terminated for any reason other than the exhaustion of its coverage, or if the
claims-paying ability rating of its issuer is reduced to below investment
grade, the Master Servicer will use its best efforts to obtain a comparable
policy from an insurer that is acceptable to the Rating Agencies. The
replacement policy will provide coverage equal to the then remaining coverage
of the Loan Insurance Policy if available. However, if the premium cost of a
replacement policy exceeds the premium cost of the Loan Insurance Policy, the
coverage amount of the replacement policy will be reduced so that its premium
cost will not exceed the premium cost of the Loan Insurance Policy.

          The Master Servicer shall forward to the Loan Insurance Policy
Provider in immediately available funds on or before 12:00 noon (New York City
time) on January 25, 2005 the initial premium due under the Loan Insurance
Policy. The Master Servicer shall withdraw from the Certificate Account and
forward to the Co-Trustee in immediately available funds on or before 12:00
noon (New York City time) on each Distribution Date the Loan Insurance Policy

                                     -68-
<PAGE>

Premium due on such Distribution Date, and (iii) promptly when due any other
amount owed to the Loan Insurance Policy Provider under the Loan Insurance
Policy.

          Section 3.10 Maintenance of Hazard Insurance.

          The Master Servicer shall cause to be maintained, for each Mortgage
Loan, hazard insurance with extended coverage in an amount that is at least
equal to the lesser of (i) the maximum insurable value of the improvements
securing such Mortgage Loan and (ii) the greater of (a) the outstanding
principal balance of the Mortgage Loan and (b) an amount such that the
proceeds of such policy shall be sufficient to prevent the related Mortgagor
and/or mortgagee from becoming a co-insurer. Each such policy of standard
hazard insurance shall contain, or have an accompanying endorsement that
contains, a standard mortgagee clause. The Master Servicer shall also cause
flood insurance to be maintained on property acquired upon foreclosure or deed
in lieu of foreclosure of any Mortgage Loan, to the extent described below.
Pursuant to Section 3.05 hereof, any amounts collected by the Master Servicer
under any such policies (other than the amounts to be applied to the
restoration or repair of the related Mortgaged Property or property thus
acquired or amounts released to the Mortgagor in accordance with the Master
Servicer's normal servicing procedures) shall be deposited in the Certificate
Account. Any cost incurred by the Master Servicer in maintaining any such
insurance shall not, for the purpose of calculating monthly distributions to
the Certificateholders or remittances to the Trustee for their benefit, be
added to the principal balance of the Mortgage Loan, notwithstanding that the
terms of the Mortgage Loan so permit. Such costs shall be recoverable by the
Master Servicer out of late payments by the related Mortgagor or out of
Liquidation Proceeds or Subsequent Recoveries to the extent permitted by
Section 3.08 hereof. It is understood and agreed that no earthquake or other
additional insurance is to be required of any Mortgagor or maintained on
property acquired in respect of a Mortgage other than pursuant to such
applicable laws and regulations as shall at any time be in force and as shall
require such additional insurance. If the Mortgaged Property is located at the
time of origination of the Mortgage Loan in a federally designated special
flood hazard area and such area is participating in the national flood
insurance program, the Master Servicer shall cause flood insurance to be
maintained with respect to such Mortgage Loan. Such flood insurance shall be
in an amount equal to the lesser of (i) the original principal balance of the
related Mortgage Loan, (ii) the replacement value of the improvements that are
part of such Mortgaged Property, or (iii) the maximum amount of such insurance
available for the related Mortgaged Property under the Flood Disaster
Protection Act of 1973, as amended.

          Section 3.11 Enforcement of Due-On-Sale Clauses; Assumption
                       Agreements.

          (a) Except as otherwise provided in this Section 3.11(a), when any
property subject to a Mortgage has been or is about to be conveyed by the
Mortgagor, the Master Servicer shall to the extent that it has knowledge of
such conveyance, enforce any due-on-sale clause contained in any Mortgage Note
or Mortgage, to the extent permitted under applicable law and governmental
regulations, but only to the extent that such enforcement will not adversely
affect or jeopardize coverage under any Required Insurance Policy.
Notwithstanding the foregoing, the Master Servicer is not required to exercise
such rights with respect to a Mortgage Loan if the Person to whom the related
Mortgaged Property has been conveyed or is proposed to be conveyed satisfies
the terms and conditions contained in the Mortgage Note and Mortgage related
thereto and the consent of the mortgagee under such Mortgage Note or Mortgage
is not

                                     -69-
<PAGE>

otherwise so required under such Mortgage Note or Mortgage as a condition to
such transfer. In the event that the Master Servicer is prohibited by law from
enforcing any such due-on-sale clause, or if coverage under any Required
Insurance Policy would be adversely affected, or if nonenforcement is
otherwise permitted hereunder, the Master Servicer is authorized, subject to
Section 3.11(b), to take or enter into an assumption and modification
agreement from or with the person to whom such property has been or is about
to be conveyed, pursuant to which such person becomes liable under the
Mortgage Note and, unless prohibited by applicable state law, the Mortgagor
remains liable thereon, provided that the Mortgage Loan shall continue to be
covered (if so covered before the Master Servicer enters such agreement) by
the applicable Required Insurance Policies. The Master Servicer, subject to
Section 3.11(b), is also authorized with the prior approval of the insurers
under any Required Insurance Policies to enter into a substitution of
liability agreement with such Person, pursuant to which the original Mortgagor
is released from liability and such Person is substituted as Mortgagor and
becomes liable under the Mortgage Note. Notwithstanding the foregoing, the
Master Servicer shall not be deemed to be in default under this Section
3.11(a) by reason of any transfer or assumption that the Master Servicer
reasonably believes it is restricted by law from preventing. The Master
Servicer shall notify the Trustee that any such substitution, modification or
assumption agreement has been completed by forwarding to the Trustee the
executed original of such substitution or assumption agreement, which document
shall be added to the related Mortgage File and shall, for all purposes, be
considered a part of such Mortgage File to the same extent as all other
documents and instruments constituting a part thereof.

          (b) Subject to the Master Servicer's duty to enforce any due-on-sale
clause to the extent set forth in Section 3.11(a) hereof, in any case in which
a Mortgaged Property has been conveyed to a Person by a Mortgagor, and such
Person is to enter into an assumption agreement or modification agreement or
supplement to the Mortgage Note or Mortgage that requires the signature of the
Trustee, or if an instrument of release signed by the Trustee is required
releasing the Mortgagor from liability on the Mortgage Loan, the Master
Servicer shall prepare and deliver or cause to be prepared and delivered to
the Trustee for signature and shall direct, in writing, the Trustee to execute
the assumption agreement with the Person to whom the Mortgaged Property is to
be conveyed and such modification agreement or supplement to the Mortgage Note
or Mortgage or other instruments as are reasonable or necessary to carry out
the terms of the Mortgage Note or Mortgage or otherwise to comply with any
applicable laws regarding assumptions or the transfer of the Mortgaged
Property to such Person. In connection with any such assumption, no material
term of the Mortgage Note (including, but not limited to, the Mortgage Rate,
the amount of the Scheduled Payment and any other term affecting the amount or
timing of payment on the Mortgage Loan) may be changed. In addition, the
substitute Mortgagor and the Mortgaged Property must be acceptable to the
Master Servicer in accordance with its underwriting standards as then in
effect. The Master Servicer shall notify the Trustee that any such
substitution or assumption agreement has been completed by forwarding to the
Trustee the original of such substitution or assumption agreement, which in
the case of the original shall be added to the related Mortgage File and
shall, for all purposes, be considered a part of such Mortgage File to the
same extent as all other documents and instruments constituting a part
thereof. Any fee collected by the Master Servicer for entering into an
assumption or substitution of liability agreement will be retained by the
Master Servicer as additional servicing compensation.

          Section 3.12 Realization Upon Defaulted Mortgage Loans;
                       Determination of Excess Proceeds and Realized
                       Losses; Repurchase of Certain Mortgage Loans.

          (a) The Master Servicer may agree to a modification of any Mortgage
Loan (the "Modified Mortgage Loan") if (i) the modification is in lieu of a
refinancing and (ii) the Mortgage Rate on the Modified Mortgage Loan is
approximately a prevailing market rate for newly originated mortgage loans
having similar terms and (iii) the Master Servicer purchases the Modified
Mortgage Loan from the Trust Fund as described below. Effective immediately
after the modification, and, in any event, on the same Business Day on which
the modification occurs, all interest of the Trustee in the Modified Mortgage
Loan shall automatically be deemed transferred and assigned to the Master
Servicer and all benefits and burdens of ownership thereof, including the
right to accrued interest thereon from the date of modification and the risk
of default thereon, shall pass to the Master Servicer. The Master Servicer
shall promptly deliver to the Trustee a certification of a Servicing Officer
to the effect that all requirements of this paragraph have been satisfied with
respect to the Modified Mortgage Loan. For federal income tax purposes, the
Trustee shall account for such purchase as a prepayment in full of the
Modified Mortgage Loan. The Master Servicer shall deposit the Purchase Price
for any Modified Mortgage Loan in the Certificate Account pursuant to Section
3.05 within one Business Day after the purchase of the Modified Mortgage Loan.
Upon receipt by the Trustee of written notification of any such deposit signed
by a Servicing Officer, the Trustee shall release to the Master Servicer the
related Mortgage File and shall execute and deliver such instruments of
transfer or assignment, in each case without recourse, as shall be necessary
to vest in the Master Servicer any Modified Mortgage Loan previously
transferred and assigned pursuant hereto. The Master Servicer covenants and
agrees to indemnify the Trust Fund against any liability for any "prohibited
transaction" taxes and any related interest, additions, and penalties imposed
on the Trust Fund established hereunder as a result of any modification of a
Mortgage Loan effected pursuant to this subsection (b), any holding of a
Modified Mortgage Loan by the Trust Fund or any purchase of a Modified
Mortgage Loan by the Master Servicer (but such obligation shall not prevent
the Master Servicer or any other appropriate Person from in good faith
contesting any such tax in appropriate proceedings and shall not prevent the
Master Servicer from withholding payment of such tax, if permitted by law,
pending the outcome of such proceedings). The Master Servicer shall have no
right of reimbursement for any amount paid pursuant to the foregoing
indemnification, except to the extent that the amount of any tax, interest,
and penalties, together with interest thereon, is refunded to the Trust Fund
or the Master Servicer. If the Master Servicer agrees to a modification of any
Mortgage Loan pursuant to this Section 3.12(a), and if such Mortgage Loan
carries a Prepayment Charge provision, the Master Servicer will deliver to the
Trustee the amount of the Prepayment Charge, if any, that would have been due
had such Mortgage Loan been prepaid at the time of such modification, for
deposit into the Certificate Account (not later than 1:00 p.m. Pacific time on
the Master Servicer Advance Date immediately succeeding the date of such
modification) for distribution in accordance with the terms of this Agreement.
The Servicer may not purchase more than 5.0% of the aggregate Cut-Off Date
Principal Balance of the Mortgage Loans under the circumstances described in
this Section 3.12(a).

          (b) The Master Servicer shall use reasonable efforts to foreclose
upon or otherwise comparably convert the ownership of properties securing such
of the Mortgage Loans

                                     -71-
<PAGE>

as come into and continue in default and as to which no satisfactory
arrangements can be made for collection of delinquent payments. In connection
with such foreclosure or other conversion, the Master Servicer shall follow
such practices and procedures as it shall deem necessary or advisable and as
shall be normal and usual in its general mortgage servicing activities and the
requirements of the insurer under any Required Insurance Policy; provided that
the Master Servicer shall not be required to expend its own funds in
connection with any foreclosure or towards the restoration of any property
unless it shall determine (i) that such restoration and/or foreclosure will
increase the proceeds of liquidation of the Mortgage Loan after reimbursement
to itself of such expenses and (ii) that such expenses will be recoverable to
it through Liquidation Proceeds (respecting which it shall have priority for
purposes of withdrawals from the Certificate Account pursuant to Section 3.08
hereof). The Master Servicer shall be responsible for all other costs and
expenses incurred by it in any such proceedings; provided that it shall be
entitled to reimbursement thereof from the proceeds of liquidation of the
related Mortgaged Property and any related Subsequent Recoveries, as
contemplated in Section 3.08 hereof. If the Master Servicer has knowledge that
a Mortgaged Property that the Master Servicer is contemplating acquiring in
foreclosure or by deed-in-lieu of foreclosure is located within a one-mile
radius of any site with environmental or hazardous waste risks known to the
Master Servicer, the Master Servicer will, prior to acquiring the Mortgaged
Property, consider such risks and only take action in accordance with its
established environmental review procedures.

          With respect to any REO Property, the deed or certificate of sale
shall be taken in the name of the Trustee for the benefit of the
Certificateholders (or the Trustee's nominee on behalf of the
Certificateholders). The Trustee's name shall be placed on the title to such
REO Property solely as the Trustee hereunder and not in its individual
capacity. The Master Servicer shall ensure that the title to such REO Property
references this Agreement and the Trustee's capacity thereunder. Pursuant to
its efforts to sell such REO Property, the Master Servicer shall either itself
or through an agent selected by the Master Servicer protect and conserve such
REO Property in the same manner and to such extent as is customary in the
locality where such REO Property is located and may, incident to its
conservation and protection of the interests of the Certificateholders, rent
the same, or any part thereof, as the Master Servicer deems to be in the best
interest of the Master Servicer and the Certificateholders for the period
prior to the sale of such REO Property. The Master Servicer shall prepare for
and deliver to the Trustee a statement with respect to each REO Property that
has been rented showing the aggregate rental income received and all expenses
incurred in connection with the management and maintenance of such REO
Property at such times as is necessary to enable the Trustee to comply with
the reporting requirements of the REMIC Provisions. The net monthly rental
income, if any, from such REO Property shall be deposited in the Certificate
Account no later than the close of business on each Determination Date. The
Master Servicer shall perform the tax reporting and withholding related to
foreclosures, abandonments and cancellation of indebtedness income as
specified by Sections 1445, 6050J and 6050P of the Code by preparing and
filing such tax and information returns, as may be required.

          In the event that the Trust Fund acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Master Servicer shall dispose of such Mortgaged Property as
soon as practicable in a manner that maximizes the Liquidation Proceeds, but
in no event later than three years after its acquisition by the Trust Fund or,
at the expense of the Trust Fund, the Master Servicer shall request, more than

                                     -72-
<PAGE>

60 days prior to the day on which such three-year period would otherwise
expire, an extension of the three-year grace period. In the event the Trustee
shall have been supplied with an Opinion of Counsel (such opinion not to be an
expense of the Trustee) to the effect that the holding by the Trust Fund of
such Mortgaged Property subsequent to such three-year period will not result
in the imposition of taxes on "prohibited transactions" of the Trust Fund as
defined in section 860F of the Code or cause any REMIC created hereunder to
fail to qualify as a REMIC at any time that any Certificates are outstanding,
and the Trust Fund may continue to hold such Mortgaged Property (subject to
any conditions contained in such Opinion of Counsel) after the expiration of
such three-year period. Notwithstanding any other provision of this Agreement,
no Mortgaged Property acquired by the Trust Fund shall be rented (or allowed
to continue to be rented) or otherwise used for the production of income by or
on behalf of the Trust Fund in such a manner or pursuant to any terms that
would (i) cause such Mortgaged Property to fail to qualify as "foreclosure
property" within the meaning of section 860G(a)(8) of the Code or (ii) subject
the Trust Fund to the imposition of any federal, state or local income taxes
on the income earned from such Mortgaged Property under section 860G(c) of the
Code or otherwise, unless the Master Servicer has agreed to indemnify and hold
harmless the Trust Fund with respect to the imposition of any such taxes.

          The decision of the Master Servicer to foreclose on a defaulted
Mortgage Loan shall be subject to a determination by the Master Servicer that
the proceeds of such foreclosure would exceed the costs and expenses of
bringing such a proceeding. The income earned from the management of any
Mortgaged Properties acquired through foreclosure or other judicial
proceeding, net of reimbursement to the Master Servicer for expenses incurred
(including any property or other taxes) in connection with such management and
net of unreimbursed Servicing Fees, Advances, Servicing Advances and any
management fee paid or to be paid with respect to the management of such
Mortgaged Property, shall be applied to the payment of principal of, and
interest on, the related defaulted Mortgage Loans (with interest accruing as
though such Mortgage Loans were still current) and all such income shall be
deemed, for all purposes in this Agreement, to be payments on account of
principal and interest on the related Mortgage Notes and shall be deposited
into the Certificate Account. To the extent the income received during a
Prepayment Period is in excess of the amount attributable to amortizing
principal and accrued interest at the related Mortgage Rate on the related
Mortgage Loan, such excess shall be considered to be a partial Principal
Prepayment for all purposes hereof.

          The Liquidation Proceeds from any liquidation of a Mortgage Loan and
any Subsequent Recoveries, net of any payment to the Master Servicer as
provided above, shall be deposited in the Certificate Account as provided in
Section 3.05 for distribution on the related Distribution Date, except that
any Excess Proceeds shall be retained by the Master Servicer as additional
servicing compensation.

          The proceeds of any Liquidated Mortgage Loan, as well as any
recovery resulting from a partial collection of Liquidation Proceeds or any
income from an REO Property, will be applied in the following order of
priority: first, to reimburse the Master Servicer for any related unreimbursed
Servicing Advances and Servicing Fees, pursuant to Section 3.08(a)(v) or this
Section 3.12; second, to reimburse the Master Servicer for any unreimbursed
Advances, pursuant to Section 3.08(a)(ii) or this Section 3.12; third, to
accrued and unpaid interest (to the extent no Advance has been made for such
amount) on the Mortgage Loan or related REO Property, at the

                                     -73-
<PAGE>

Net Mortgage Rate to the Due Date occurring in the month in which such amounts
are required to be distributed; and fourth, as a recovery of principal of the
Mortgage Loan.

          (c) On each Determination Date, the Master Servicer shall determine
the respective aggregate amounts of Excess Proceeds and Realized Losses, if
any, in connection with the related Distribution Date.

          (d) The Master Servicer, in its sole discretion, shall have the
right to elect (by written notice sent to the Trustee) to purchase for its own
account from the Trust Fund any Mortgage Loan that is 150 days or more
delinquent at a price equal to the Purchase Price; provided, however, that the
Master Servicer may only exercise this right on or before the last day of the
calendar month in which such Mortgage Loan became 150 days delinquent (such
month, the "Eligible Repurchase Month"); provided further, that any such
Mortgage Loan which becomes current but thereafter becomes delinquent may be
purchased by the Master Servicer pursuant to this Section in any ensuing
Eligible Repurchase Month. The Purchase Price for any Mortgage Loan purchased
hereunder shall be deposited in the Certificate Account. Any purchase of a
Mortgage Loan pursuant to this Section 3.12(d) shall be accomplished by
remittance to the Master Servicer for deposit in the Certificate Account of
the Purchase Price. The Trustee, upon receipt of certification from the Master
Servicer of such deposit and a Request for File Release from the Master
Servicer, shall release or cause to be released to the purchaser of such
Mortgage Loan the related Mortgage File and shall execute and deliver such
instruments of transfer or assignment prepared by the purchaser of such
Mortgage Loan, in each case without recourse, as shall be necessary to vest in
the purchaser of such Mortgage Loan any Mortgage Loan released pursuant hereto
and the purchaser of such Mortgage Loan shall succeed to all the Trustee's
right, title and interest in and to such Mortgage Loan and all security and
documents related thereto. Such assignment shall be an assignment outright and
not for security. The purchaser of such Mortgage Loan shall thereupon own such
Mortgage Loan, and all security and documents, free of any further obligation
to the Trustee or the Certificateholders with respect thereto.

          Section 3.13 Trustee to Cooperate; Release of Mortgage Files.

          Upon the payment in full of any Mortgage Loan, or the receipt by the
Master Servicer of a notification that payment in full will be escrowed in a
manner customary for such purposes, the Master Servicer will promptly notify
the Trustee by delivering a Request for File Release. Upon receipt of such
request, the Trustee shall promptly release the related Mortgage File to the
Master Servicer, and the Trustee shall at the Master Servicer's direction
execute and deliver to the Master Servicer the request for reconveyance, deed
of reconveyance or release or satisfaction of mortgage or such instrument
releasing the lien of the Mortgage in each case provided by the Master
Servicer, together with the Mortgage Note with written evidence of
cancellation thereon. The Master Servicer is authorized to cause the removal
from the registration on the MERS(R) System of such Mortgage and to execute
and deliver, on behalf of the Trust Fund and the Certificateholders or any of
them, any and all instruments of satisfaction or cancellation or of partial or
full release. No expenses incurred in connection with any instrument of
satisfaction or deed of reconveyance shall be chargeable to the Certificate
Account, the Distribution Account, the Carryover Reserve Fund or the related
subservicing account. From time to time and as shall be appropriate for the
servicing or foreclosure of any Mortgage Loan,

                                     -74-
<PAGE>

including for such purpose, collection under any policy of flood insurance any
fidelity bond or errors or omissions policy, or for the purposes of effecting
a partial release of any Mortgaged Property from the lien of the Mortgage or
the making of any corrections to the Mortgage Note or the Mortgage or any of
the other documents included in the Mortgage File, the Trustee shall, upon
delivery to the Trustee of a Request for Document Release or a Request for
File Release, as applicable, release the document specified in such request or
the Mortgage File, as the case may be, to the Master Servicer. Subject to the
further limitations set forth below, the Master Servicer shall cause the
Mortgage File or documents so released to be returned to the Trustee when the
need therefor by the Master Servicer no longer exists, unless the Mortgage
Loan is liquidated and the proceeds thereof are deposited in the Certificate
Account, in which case the Master Servicer shall deliver to the Trustee a
Request for File Release for any remaining documents in the Mortgage File not
in the possession of the Master Servicer.

          If the Master Servicer at any time seeks to initiate a foreclosure
proceeding in respect of any Mortgaged Property as authorized by this
Agreement, the Master Servicer shall deliver or cause to be delivered to the
Trustee, for signature, as appropriate, any court pleadings, requests for
trustee's sale or other documents necessary to effectuate such foreclosure or
any legal action brought to obtain judgment against the Mortgagor on the
Mortgage Note or the Mortgage or to obtain a deficiency judgment or to enforce
any other remedies or rights provided by the Mortgage Note or the Mortgage or
otherwise available at law or in equity. Notwithstanding the foregoing, the
Master Servicer shall cause possession of any Mortgage File or of the
documents therein that shall have been released by the Trustee to be returned
to the Trustee within 21 calendar days after possession thereof shall have
been released by the Trustee unless (i) the Mortgage Loan has been liquidated
and the Liquidation Proceeds relating to the Mortgage Loan have been deposited
in the Certificate Account, and the Master Servicer shall have delivered to
the Trustee a Request for File Release or (ii) the Mortgage File or document
shall have been delivered to an attorney or to a public trustee or other
public official as required by law for purposes of initiating or pursuing
legal action or other proceedings for the foreclosure of the Mortgaged
Property and the Master Servicer shall have delivered to the Trustee an
Officer's Certificate of a Servicing Officer certifying as to the name and
address of the Person to which the Mortgage File or the documents therein were
delivered and the purpose or purposes of such delivery.

          Section 3.14 Documents, Records and Funds in Possession of Master
                       Servicer to be Held for the Trustee.

          Notwithstanding any other provisions of this Agreement, the Master
Servicer shall transmit to the Trustee as required by this Agreement all
documents and instruments in respect of a Mortgage Loan coming into the
possession of the Master Servicer from time to time and shall account fully to
the Trustee for any funds received by the Master Servicer or that otherwise
are collected by the Master Servicer as Liquidation Proceeds, Insurance
Proceeds or Subsequent Recoveries in respect of any Mortgage Loan. All
Mortgage Files and funds collected or held by, or under the control of, the
Master Servicer in respect of any Mortgage Loans, whether from the collection
of principal and interest payments or from Liquidation Proceeds or Subsequent
Recoveries, including but not limited to, any funds on deposit in the
Certificate Account, shall be held by the Master Servicer for and on behalf of
the Trust Fund and shall be and remain the sole and exclusive property of the
Trust Fund, subject to the applicable

                                     -75-
<PAGE>

provisions of this Agreement. The Master Servicer also agrees that it shall
not create, incur or subject any Mortgage File or any funds that are deposited
in the Certificate Account, Distribution Account, or Carryover Reserve Fund or
in any Escrow Account (as defined in Section 3.06), or any funds that
otherwise are or may become due or payable to the Trustee for the benefit of
the Certificateholders, to any claim, lien, security interest, judgment, levy,
writ of attachment or other encumbrance, or assert by legal action or
otherwise any claim or right of set off against any Mortgage File or any funds
collected on, or in connection with, a Mortgage Loan, except, however, that
the Master Servicer shall be entitled to set off against and deduct from any
such funds any amounts that are properly due and payable to the Master
Servicer under this Agreement.

          Section 3.15 Servicing Compensation.

          As compensation for its activities hereunder, the Master Servicer
shall be entitled to retain or withdraw from the Certificate Account out of
each payment of interest on a Mortgage Loan included in the Trust Fund an
amount equal to interest at the applicable Servicing Fee Rate on the Stated
Principal Balance of the related Mortgage Loan for the period covered by such
interest payment.

          Additional servicing compensation in the form of any Excess
Proceeds, assumption fees, late payment charges, Prepayment Interest Excess,
and all income and gain net of any losses realized from Permitted Investments
shall be retained by the Master Servicer to the extent not required to be
deposited in the Certificate Account pursuant to Section 3.05 or 3.12(b)
hereof. The Master Servicer shall be required to pay all expenses incurred by
it in connection with its servicing activities hereunder (including payment of
any premiums for hazard insurance, as required by Section 3.10 hereof and
maintenance of the other forms of insurance coverage required by Section 3.10
hereof) and shall not be entitled to reimbursement therefor except as
specifically provided in Sections 3.08 and 3.12 hereof.

          Section 3.16 Access to Certain Documentation.

          The Master Servicer shall provide to the OTS and the FDIC and to
comparable regulatory authorities supervising Holders of the Certificates
and/or Certificate Owners and the examiners and supervisory agents of the OTS,
the FDIC and such other authorities, access to the documentation regarding the
Mortgage Loans required by applicable regulations of the OTS and the FDIC.
Such access shall be afforded without charge, but only upon reasonable and
prior written request and during normal business hours at the offices of the
Master Servicer designated by it. Nothing in this Section shall limit the
obligation of the Master Servicer to observe any applicable law prohibiting
disclosure of information regarding the Mortgagors and the failure of the
Master Servicer to provide access as provided in this Section as a result of
such obligation shall not constitute a breach of this Section.

          Section 3.17 Annual Statement as to Compliance.

          The Master Servicer shall deliver to the Depositor and the Trustee
on or before the 80th day after the end of the Master Servicer's fiscal year,
commencing with its 2004 fiscal year, an Officer's Certificate stating, as to
the signer thereof, that (i) a review of the activities of

                                     -76-

the Master Servicer during the preceding calendar year and of the performance
of the Master Servicer under this Agreement has been made under such officer's
supervision and (ii) to the best of such officer's knowledge, based on such
review, the Master Servicer has fulfilled all its obligations under this
Agreement throughout such year, or, if there has been a default in the
fulfillment of any such obligation, specifying each such default known to such
officer and the nature and status thereof and (iii) to the best of such
officer's knowledge, each Subservicer has fulfilled all its obligations under
its Subservicing Agreement throughout such year, or, if there has been a
default in the fulfillment of any such obligation specifying each such default
known to such officer and the nature and status thereof. The Trustee shall
forward a copy of each such statement to each Rating Agency. Copies of such
statement shall be provided by the Trustee to any Certificateholder or
Certificate Owner upon request at the Master Servicer's expense, provided such
statement is delivered by the Master Servicer to the Trustee.

          Section 3.18 Annual Independent Public Accountants' Servicing
                       Statement; Financial Statements.

          On or before the later of (i) the 80th day after the end of the
Master Servicer's fiscal year, commencing with its 2004 fiscal year or (ii)
within 30 days of the issuance of the annual audited financial statements

its expense shall cause a nationally recognized firm of independent public
accountants (who may also render other services to the Master Servicer, the
Seller or any affiliate thereof) that is a member of the American Institute of
Certified Public Accountants to furnish a report to the Trustee, the Depositor
and the Seller in compliance with the Uniform Single Attestation Program for
Mortgage Bankers. Copies of such report shall be provided by the Trustee to
any Certificateholder or Certificate Owner upon request at the Master
Servicer's expense, provided such report is delivered by the Master Servicer
to the Trustee. Upon written request, the Master Servicer shall provide to the
Certificateholders or Certificate Owners its publicly available annual
financial statements (or the Master Servicer's parent company's publicly
available annual financial statements, as applicable), if any, promptly after
they become available.

          Section 3.19 The Corridor Contract.

          The Seller shall assign all of its right, title and interest in and
to the Corridor Contract evidenced by the Confirmation to, and shall cause all
of its obligations in respect of such transactions to be assumed by, the
Trustee on behalf of the Trust Fund, on the terms and conditions set forth in
the Corridor Contract Assignment Agreement. The Corridor Contract will be an
asset of the Trust Fund but will not be an asset of any REMIC. The Master
Servicer, on behalf of the Trustee, shall deposit any amounts received from
time to time with respect to the Corridor Contract into the Carryover Reserve
Fund.

          The Master Servicer, on behalf of the Trustee, shall prepare and
deliver any notices required to be delivered under the Corridor Contract.

          The Master Servicer, on behalf of the Trustee, shall act as
calculation agent and/or shall terminate the Corridor Contract, in each case
upon the occurrence of certain events of default or termination events to the
extent specified thereunder. Upon any such termination, the

                                     -77-
<PAGE>

Corridor Contract Counterparty will be obligated to pay the Trustee or the
Master Servicer for the benefit of the Trust Fund an amount in respect of such
termination. Any amounts received by the Trustee or the Master Servicer for
the benefit of the Trust Fund, as the case may be, in respect of such
termination shall be deposited and held in the Carryover Reserve Fund to pay
Net Rate Carryover for the applicable Classes of Certificates as provided in
Section 4.04(e) on the Distribution Dates following such termination to and
including the Corridor Contract Termination Date, but shall not be available
for distribution to the Class A-IO Certificates pursuant to Section 4.09(c)
until the Corridor Contract Termination Date. On the Corridor Contract
Termination Date, after all other distributions on such date have been made
hereunder, if any amounts received by the Trustee for the benefit of the Trust
Fund in respect of early termination of the Corridor Contract remain in the
Carryover Reserve Fund, such amounts shall be distributed by the Trustee to
the Class A-IO Certificates.

          Section 3.20 Prepayment Charges.

          (a) Notwithstanding anything in this Agreement to the contrary, in
the event of a Principal Prepayment in full or in part of a Mortgage Loan, the
Master Servicer may not waive any Prepayment Charge or portion thereof
required by the terms of the related Mortgage Note unless (i) such Mortgage
Loan is in default or the Master Servicer believes that such a default is
imminent, and the Master Servicer determines that such waiver would maximize
recovery of Liquidation Proceeds for such Mortgage Loan, taking into account
the value of such Prepayment Charge, or (ii) (A) the enforceability thereof is
limited (1) by bankruptcy, insolvency, moratorium, receivership, or other
similar law relating to creditors' rights generally or (2) due to acceleration
in connection with a foreclosure or other involuntary payment, or (B) the
enforceability is otherwise limited or prohibited by applicable law. In the
event of a Principal Prepayment in full or in part with respect to any
Mortgage Loan, the Master Servicer shall deliver to the Trustee an Officer's
Certificate substantially in the form of Exhibit T no later than the third
Business Day following the immediately succeeding Determination Date with a
copy to the Class P Certificateholders. If the Master Servicer has waived or
does not collect all or a portion of a Prepayment Charge relating to a
Principal Prepayment in full or in part due to any action or omission of the
Master Servicer, other than as provided above, the Master Servicer shall
deliver to the Trustee, together with the Principal Prepayment in full or in
part, the amount of such Prepayment Charge (or such portion thereof as had
been waived) for deposit into the Certificate Account (not later than 1:00
p.m. Pacific time on the immediately succeeding Master Servicer Advance Date,
in the case of such Prepayment Charge) for distribution in accordance with the
terms of this Agreement.

          (b) Upon discovery by the Master Servicer or a Responsible Officer
of the Trustee of a breach of Section 3.20(a), the party discovering the
breach shall give prompt written notice to the other parties.

          (c) The Seller represents and warrants to the Depositor and the
Trustee that, as of the Closing Date, the information in the Prepayment Charge
Schedule (including the attached prepayment charge summary) is complete and
accurate in all material respects at the dates as of which the information is
furnished and each Prepayment Charge is permissible and enforceable in
accordance with its terms under applicable state law, except as the
enforceability

                                     -78-
<PAGE>

thereof is limited due to acceleration in connection with a foreclosure or
other involuntary payment.

          (d) Upon discovery by the Master Servicer or a Responsible Officer
of the Trustee of a breach of the foregoing clause (c) that materially and
adversely affects right of the Holders of the Class P Certificates to any
Prepayment Charge, the party discovering the breach shall give prompt written
notice to the other parties. Within 60 days of the earlier of discovery by the
Seller or receipt of notice by the Seller of breach, the Seller shall cure the
breach in all material respects or shall pay into the Certificate Account the
amount of the Prepayment Charge that would otherwise be due from the
Mortgagor, less any amount representing such Prepayment Charge previously
collected and paid by the Master Servicer into the Certificate Account.

                                 ARTICLE IV.

                               DISTRIBUTIONS AND
                        ADVANCES BY THE MASTER SERVICER

          Section 4.01 Advances.

          (a) [Reserved.]

          (b) Subject to the conditions of this Article IV, the Master
Servicer, as required below, shall make an Advance and deposit such Advance in
the Certificate Account. Each such Advance shall be remitted to the
Certificate Account no later than 1:00 p.m. Pacific time on the Master
Servicer Advance Date in immediately available funds. The Trustee shall
provide notice to the Master Servicer by facsimile by the close of business on
any Master Servicer Advance Date if the amount remitted by the Master Servicer
to the Trustee on the Distribution Account Deposit Date is less than the
Advances required to be made by the Master Servicer for such Distribution
Date. The Master Servicer shall be obligated to make any such Advance only to
the extent that such advance would not be a Nonrecoverable Advance. If the
Master Servicer shall have determined that it has made a Nonrecoverable
Advance or that a proposed Advance or a lesser portion of such Advance would
constitute a Nonrecoverable Advance, the Master Servicer shall deliver (i) to
the Trustee for the benefit of the Certificateholders funds constituting the
remaining portion of such Advance, if applicable, and (ii) to the Depositor,
each Rating Agency and the Trustee an Officer's Certificate setting forth the
basis for such determination.

          (c) In lieu of making all or a portion of such Advance from its own
funds, the Master Servicer may (i) cause to be made an appropriate entry in
its records relating to the Certificate Account that any Amount Held for
Future Distributions has been used by the Master Servicer in discharge of its
obligation to make any such Advance and (ii) transfer such funds from the
Certificate Account to the Distribution Account. Any funds so applied and
transferred shall be replaced by the Master Servicer by deposit in the
Certificate Account no later than the close of business on the Business Day
immediately preceding the Distribution Date on which such funds are required
to be distributed pursuant to this Agreement. The Master Servicer shall

                                     -79-
<PAGE>

be entitled to be reimbursed from the Certificate Account for all Advances of
its own funds made pursuant to this Section as provided in Section 3.08. The
obligation to make Advances with respect to any Mortgage Loan shall continue
until such Mortgage Loan is paid in full or the related Mortgaged Property or
related REO Property has been liquidated or until the purchase or repurchase
thereof (or substitution therefor) from the Trustee pursuant to any applicable
provision of this Agreement, except as otherwise provided in this Section
4.01.

          (d) If the Master Servicer determines that it will be unable to
comply with its obligation to make the Advances as and when described in
paragraphs (b) and (c) immediately above, it shall use its best efforts to
give written notice thereof to the Trustee (each such notice a "Trustee
Advance Notice"; and such notice may be given by facsimile), not later than
3:00 P.M., New York time, on the Business Day immediately preceding the
related Master Servicer Advance Date, specifying the amount that it will be
unable to deposit (each such amount an "Advance Deficiency") and certifying
that such Advance Deficiency constitutes an Advance hereunder and is not a
Nonrecoverable Advance. If the Trustee receives a Trustee Advance Notice on or
before 3:30 P.M., New York time, on a Master Servicer Advance Date, the
Trustee shall, not later than 3:00 P.M., New York time, on the related
Distribution Date, deposit in the Distribution Account an amount equal to the
Advance Deficiency identified in such Trustee Advance Notice unless it is
prohibited from so doing by applicable law. Notwithstanding the foregoing, the
Trustee shall not be required to make such deposit if the Trustee shall have
received written notification from the Master Servicer that the Master
Servicer has deposited or caused to be deposited in the Certificate Account an
amount equal to such Advance Deficiency. All Advances made by the Trustee
pursuant to this Section 4.01(d) shall accrue interest on behalf of the
Trustee at the Trustee Advance Rate from and including the date such Advances
are made to but excluding the date of repayment, with such interest being an
obligation of the Master Servicer and not the Trust Fund. The Master Servicer
shall reimburse the Trustee for the amount of any Advance made by the Trustee
pursuant to this Section 4.01(d) together with accrued interest, not later
than 6:00 P.M., New York time, on the Business Day following the related
Distribution Date. In the event that the Master Servicer does not reimburse
the Trustee in accordance with the requirements of the preceding sentence, the
Trustee shall immediately (a) terminate all of the rights and obligations of
the Master Servicer under this Agreement in accordance with Section 7.01 and
(b) subject to the limitations set forth in Section 3.04, assume all of the
rights and obligations of the Master Servicer hereunder.

          (e) The Master Servicer shall, not later than the close of business
on the second Business Day immediately preceding each Distribution Date,
deliver to the Trustee a report (in form and substance reasonably satisfactory
to the Trustee) that indicates (i) the Mortgage Loans with respect to which
the Master Servicer has determined that Scheduled Payments should be advanced
and (ii) the amount of such Scheduled Payments. The Master Servicer shall
deliver to the Trustee on the related Master Servicer Advance Date an
Officer's Certificate of a Servicing Officer indicating the amount of any
proposed Advance determined by the Master Servicer to be a Nonrecoverable
Advance.

          Section 4.02 Reduction of Servicing Compensation in Connection with
                       Prepayment Interest Shortfalls.

          In the event that any Mortgage Loan is the subject of a Prepayment
Interest Shortfall, the Master Servicer shall remit the related Compensating
Interest, if any, as part of the Interest Remittance Amount, as provided in
this Agreement. The Master Servicer shall not be entitled to any recovery or
reimbursement for Compensating Interest from the Depositor, the Trustee, the
Seller, the Trust Fund or the Certificateholders.

          Section 4.03 [Reserved]

          Section 4.04 Distributions.

          (a) On each Distribution Date, the Interest Funds for such
Distribution Date shall be allocated by the Trustee from the Distribution
Account in the following order of priority:

               (i) concurrently, to the Class A-1, Class A-2, Class A-3 and
     Class A-IO Certificates, the Current Interest and any Interest Carry
     Forward Amount for each such Class; provided, however, that the Current
     Interest and any Interest Carry Forward Amount payable to the Class A-IO
     Certificates shall be deposited in the Carryover Reserve Fund as provided
     in Section 4.09 in an amount equal to the sum of the Primary Carryover
     Reserve Fund Deposit and the Secondary Carryover Reserve Fund Deposit,
     and any remaining amount shall be distributed to the Class A-IO
     Certificates; and provided, further, that if the Interest Funds are not
     sufficient to make a full distribution of the aggregate Current Interest
     and the aggregate Interest Carry Forward Amount for each such Class of
     Certificates, such Interest Funds will be distributed pro rata among each
     such Class, based on the ratio of (x) the portion of the Current Interest
     and the portion of any Interest Carry Forward Amount attributable to such
     Class to (y) the portion of Current Interest and the portion of any
     Interest Carry Forward Amount attributable to all such Classes;

               (ii) to the Class M-1 Certificates, the Current Interest and
     any Interest Carry Forward Amount for such Class,

               (iii) to the Class M-2 Certificates, the Current Interest and
     any Interest Carry Forward Amount for such Class,

               (iv) to the Class M-3 Certificates, the Current Interest and
     any Interest Carry Forward Amount for such Class, and

               (v) any remainder to the Class A-R Certificates.

          (b) [Reserved]

          (c) On each Distribution Date on or prior to the Corridor Contract
Termination Date, amounts received by the Trustee in respect of the Corridor
Contract for such Distribution Date shall be withdrawn from the Carryover
Reserve Fund and distributed in the following order of priority:

                                     -81-
<PAGE>

          (1) first, to the Class A-1 Certificates, to the extent needed to
pay any Class A-1 Interest Carryover Amount; and

          (2) second, to the Class A-IO Certificates, any remaining amounts,
unless the Corridor Contract is subject to early termination, in which case
any early termination payments received on the Corridor Contract shall be
deposited by the Trustee in the Carryover Reserve Fund to cover any Class A-1
Interest Carryover Amount on future Distribution Dates until the Corridor
Contract Termination Date.

          On each Distribution Date, after the deposit in the Carryover
Reserve Fund of the Primary Carryover Reserve Fund Deposit as provided in
Section 4.04(a)(i) above, but prior to the deposit in the Carryover Reserve
Fund of the Secondary Carryover Reserve Fund Deposit as provided in Section
4.04(a)(i) above, and after giving effect to the distribution of Corridor
Contract proceeds to the Class A-1 Certificates, amounts on deposit in the
Carryover Reserve Fund shall be allocated by the Trustee to each Class of
Certificates (other than the Class A-IO Certificates) to the extent of any
remaining Net Rate Carryover for such Class of Certificates for such
Distribution Date on a pro rata basis among all such Classes (on the basis of
the Net Rate Carryover for each such Class).

          (d) On each Distribution Date, the Principal Distribution Amount for
such Distribution Date shall be allocated by the Trustee from the Distribution
Account in the following order of priority:

               (i) with respect to any Distribution Date prior to the Stepdown
     Date or on which a Trigger Event is in effect:

               (A) to the Class A-R Certificates, until the Certificate
          Principal Balance thereof is reduced to zero;

               (B) to the Class A Certificates in the order and the priorities
          set forth in Section 4.04(e) below;

               (C) to the Class M-1 Certificates, until the Certificate
          Principal Balance thereof is reduced to zero;

          Principal Balance thereof is reduced to zero; and

               (F) any remainder to the Class A-R Certificates; and

               (ii) with respect to each Distribution Date on and after the
     Stepdown Date and on which a Trigger Event is not in effect:

          Distribution Amount, in the order and the priorities set forth in
          Section 4.04(e) below;

<PAGE>

               (B) to the Class M-1 Certificates, the Class M-1 Principal
          Distribution Amount, until the Certificate Principal Balance thereof
          is reduced to zero;

               (C) to the Class M-2 Certificates, the Class M-2 Principal
          Distribution Amount, until the Certificate Principal Balance thereof
          is reduced to zero;

               (D) to the Class M-3 Certificates, the Class M-3 Principal
          Distribution Amount, until the Certificate Principal Balance thereof
          is reduced to zero; and

               (E) any remainder to the Class A-R Certificates.

          (e) On each Distribution Date, the Principal Distribution Amount or
the Class A Principal Distribution Amount, as applicable, allocated under
Section 4.04(d) to the Class A Certificates is required to be further
allocated by the Trustee to the Class A Certificates in the following order
and priority:

               (i) to the Class A-1 Certificates, until the Certificate
     Principal Balance thereof has been reduced to zero;

               (ii) to the Class A-2 Certificates, until the Certificate
     Principal Balance thereof has been reduced to zero; and

               (iii) to the Class A-3 Certificates, until the Certificate
     Principal Balance thereof has been reduced to zero;

provided that, on any Distribution Date on which the Aggregate Class A
Certificate Principal Balance (calculated for this purpose after taking into
account all distributions of principal on such Distribution Date) is greater
than the sum of the Stated Principal Balances of the Mortgage Loans as of such
Distribution Date, the Principal Distribution Amount or the Class A Principal
Distribution Amount, as applicable, shall be distributed pro rata among each
Class of Class A Certificates (in accordance with the respective Certificate
Principal Balances thereof) and not sequentially.

          (f) For applicable tax purposes, to the extent that a Class of
Certificates (other than the Class A-IO Certificates) receives interest in
excess of the Net Rate Cap the excess shall be treated as having been
distributed to the Class A-IO Certificateholders, then paid to the Carryover
Reserve Fund and then paid to such receiving Certificateholders.

          (g) On each Distribution Date, all Prepayment Charges (including
amounts deposited in connection with the full or partial waiver of such
Prepayment Charges pursuant to Section 3.20) shall be allocated and paid to
the Class P Certificates. On the Class P Principal Distribution Date, the
Trustee shall make the $100.00 distribution to the Class P Certificates as
specified in Section 3.08.

          (h) On each Distribution Date, the Trustee shall allocate the
Applied Realized Loss Amount to reduce the Certificate Principal Balances of
the Subordinate Certificates in the following order of priority:

                                     -83-

               (i) to the Class M-3 Certificates until the Class M-3
     Certificate Principal Balance is reduced to zero;

               (ii) to the Class M-2 Certificates until the Class M-2
     Certificate Principal Balance is reduced to zero; and

Applied Realized Loss Amounts have been previously allocated in the following

               (i) to the Class M-1 Certificates, but not by more than the
     amount of the Unpaid Realized Loss Amount of the Class M-1 Certificates;

               (ii) to the Class M-2 Certificates, but not by more than the
     amount of the Unpaid Realized Loss Amount of the Class M-2 Certificates;
     and

               (iii) to the Class M-3 Certificates, but not by more than the
     amount of the Unpaid Realized Loss Amount of the Class M-3 Certificates.

          Subject to Section 9.02 hereof respecting the final distribution, on
each Distribution Date the Trustee shall make distributions to each
Certificateholder of record on the preceding Record Date either by wire
transfer in immediately available funds to the account of such holder at a
bank or other entity having appropriate facilities therefor, if (i) such
Holder has so notified the Trustee at least 5 Business Days prior to the
related Record Date and (ii) such Holder shall hold Regular Certificates with
aggregate principal denominations of not less than $1,000,000 or evidencing a
Percentage Interest aggregating 10% or more with respect to such Class or, if
not, by check mailed by first class mail to such Certificateholder at the
address of such holder appearing in the Certificate Register. Notwithstanding
the foregoing, but subject to Section 9.02 hereof respecting the final
distribution, distributions with respect to Certificates registered in the
name of a Depository shall be made to such Depository in immediately available
funds.

          On or before 5:00 p.m. Pacific time on the fifth Business Day
following each Determination Date (but in no event later than 5:00 p.m.
Pacific time on the third Business Day before the related Distribution Date),
the Master Servicer shall deliver a report to the Trustee in the form of a
computer readable magnetic tape (or by such other means as the Master Servicer
and the Trustee may agree from time to time) containing such data and
information as agreed to by the Master Servicer and the Trustee such as to
permit the Trustee to prepare the Monthly Statement to Certificateholders and
make the required distributions for the related Distribution Date (the
"Remittance Report"). The Trustee shall, not later than 9:00 a.m. Pacific time
on the Master Servicer Advance Date, other than any Master Servicer Advance
Date relating to any Distribution Date on which the proceeds of any Optional
Termination are being distributed, (i) furnish by telecopy a statement to the

Certificateholders by the Trustee on request) setting forth the Interest Funds

                                     -84-
<PAGE>

and Principal Funds for such Distribution Date and the amount to be withdrawn
from the Certificate Account and (ii) determine (and notify the Master
Servicer by telecopy of the results of such determination) the amount of
Advances to be made by the Master Servicer in respect of the related
Distribution Date; provided that no Advance shall be made if it would be a
Nonrecoverable Advance; provided further that any failure by the Trustee to
notify the Master Servicer shall not relieve the Master Servicer from any
obligation to make any such Advances. The Trustee shall not be responsible to
recompute, recalculate or verify information provided to it by the Master
Servicer and shall be permitted to conclusively rely on any information
provided to it by the Master Servicer.

          Section 4.05 Monthly Statements to Certificateholders.

          (a) Not later than each Distribution Date, the Trustee shall prepare

               (ii) the amount of such distribution to Holders of each Class
     allocable to interest;

               (iii) any Interest Carry Forward Amount for each Class;

          Section 4.09 Carryover Reserve Fund.

          (a) On the Closing Date, the Trustee shall establish and maintain in
its name, in trust for the benefit of the Holders of the Certificates, the
Carryover Reserve Fund. The Carryover Reserve Fund shall be an Eligible
Account, and funds on deposit therein shall be held separate and apart from,
and shall not be commingled with, any other moneys, including without
limitation, other moneys held by the Trustee pursuant to this Agreement. On
the Closing Date, the Seller shall remit $10,000 to the Trustee, which shall
deposit such funds in the Carryover Reserve Fund.

          (b) On each Distribution Date, the Trustee shall deposit all amounts
received pursuant to the Corridor Contract in the Carryover Reserve Fund. The
Trustee shall make withdrawals from the Carryover Reserve Fund to make
distributions pursuant to Section 4.04(c) hereof.

          (c) Any amounts received on the Corridor Contract with respect to a
Distribution Date and remaining after the distributions required pursuant to
Section 4.04(c) shall be distributed to the Class A-IO Certificates; provided,
however, that if the Corridor Contract is subject to early termination, early
termination payments received on the Corridor Contract shall be deposited by
the Trustee in the Carryover Reserve Fund and withdrawn from the Carryover
Reserve Fund to pay any Net Rate Carryover on the related Classes of
Certificates as provided in Section 4.04(c) on the Distribution Dates
following such termination to and including the Corridor Contract Termination
Date, but such early termination payments shall not be available for
distribution to the Class A-IO Certificates on future Distribution Dates until
the Corridor Contract Termination Date.

          (d) Funds in the Carryover Reserve Fund may be invested in Permitted
Investments. Any earnings on such amounts shall be payable to the Class A-IO
Certificates. The Class A-IO Certificates shall evidence ownership of the
Carryover Reserve Fund for federal tax purposes and the Holders thereof
evidencing not less than 50% of the Voting Rights of such Class shall direct
the Trustee in writing as to the investment of amounts therein. In the absence
of such written direction, all funds in the Carryover Reserve Fund shall be
invested by the Trustee in The Bank of New York cash reserves.

          (e) Upon termination of the Trust Fund, any amounts remaining in the

(1) Notional Amount.
(2) The Tax Matters Person Certificate may be issued in a denomination of
$0.50.

          The Certificates shall be executed by manual or facsimile signature
on behalf of the Trustee by an authorized officer. Certificates bearing the
manual or facsimile signatures of individuals who were, at the time when such
signatures were affixed, authorized to sign on behalf of the Trustee shall
bind the Trustee, notwithstanding that such individuals or any of them have
ceased to be so authorized prior to the authentication and delivery of such
Certificates or did not hold such offices at the date of such authentication
and delivery. No Certificate shall be entitled to any benefit under this
Agreement, or be valid for any purpose, unless there appears on such
Certificate a certificate of authentication substantially in the form set
forth as attached hereto executed by the Trustee by manual signature, and such
certificate of authentication upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the
date of their authentication. On the Closing Date, the Trustee shall
authenticate the Certificates to be issued at the written direction of the
Depositor, or any affiliate thereof.

          The Depositor shall provide, or cause to be provided, to the Trustee
on a continuous basis, an adequate inventory of certificates to facilitate
transfers.

          Section 5.02 Certificate Register; Registration of Transfer and
                       Exchange of Certificates.

          (a) The Trustee shall maintain a Certificate Register for the Trust
Fund in which, subject to the provisions of subsections (b) and (c) below and
to such reasonable

                                     -90-
<PAGE>

regulations as it may prescribe, the Trustee shall provide for the
registration of Certificates and of Transfers and exchanges of Certificates as
herein provided. Upon surrender for registration of Transfer of any
Certificate, the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Certificates of the same
Class and of like aggregate Percentage Interest.

          At the option of a Certificateholder, Certificates may be exchanged
for other Certificates of the same Class in authorized denominations and
evidencing the same aggregate Percentage Interest upon surrender of the
Certificates to be exchanged at the office or agency of the Trustee. Whenever
any Certificates are so surrendered for exchange, the Trustee shall execute,
authenticate, and deliver the Certificates that the Certificateholder making
the exchange is entitled to receive. Every Certificate presented or
surrendered for registration of Transfer or exchange shall be accompanied by a
written instrument of Transfer in form satisfactory to the Trustee duly
executed by the holder thereof or his attorney duly authorized in writing.

          No service charge to the Certificateholders shall be made for any
registration of Transfer or exchange of Certificates, but payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any Transfer or exchange of Certificates may be required.

          All Certificates surrendered for registration of Transfer or
exchange shall be canceled and subsequently destroyed by the Trustee in
accordance with the Trustee's customary procedures.

          (b) No Transfer of a Private Certificate shall be made unless such
Transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under the Securities Act and such state securities
laws. If a transfer is to be made in reliance upon an exemption from the
Securities Act and such state securities laws, in order to assure compliance
with the Securities Act and such state securities laws, the Certificateholder
desiring to effect such Transfer and such Certificateholder's prospective
transferee shall each certify to the Trustee in writing the facts surrounding
the Transfer in substantially the forms set forth in Exhibit J (the
"Transferor Certificate") and (i) deliver a letter in substantially the form
of either Exhibit K (the "Investment Letter") or Exhibit L (the "Rule 144A
Letter") or (ii) there shall be delivered to the Trustee at the expense of the
Certificateholder desiring to effect such transfer an Opinion of Counsel that
such Transfer may be made pursuant to an exemption from the Securities Act.
The Depositor shall provide to any Holder of a Private Certificate and any
prospective transferee designated by any such Holder, information regarding
the related Certificates and the Mortgage Loans and such other information as
shall be necessary to satisfy the condition to eligibility set forth in Rule
144A(d)(4) for transfer of any such Certificate without registration thereof
under the Securities Act pursuant to the registration exemption provided by
Rule 144A. The Trustee and the Master Servicer shall cooperate with the
Depositor in providing the Rule 144A information referenced in the preceding
sentence, including providing to the Depositor such information regarding the
Certificates, the Mortgage Loans and other matters regarding the Trust Fund as
the Depositor shall reasonably request to meet its obligation under the
preceding sentence. Each Holder of a Private Certificate desiring to effect
such Transfer shall, and does hereby agree to, indemnify the Trustee, the
Co-Trustee, the Depositor, the Trust Fund, each Seller and the Master Servicer

                                     -91-
<PAGE>

against any liability that may result if the Transfer is not so exempt or is
not made in accordance with such federal and state laws.

          No Transfer of an ERISA-Restricted Certificate shall be made unless
the Trustee shall have received either (i) a representation from the
transferee of such Certificate acceptable to and in form and substance
satisfactory to the Trustee (in the event such Certificate is a Private
Certificate, such requirement is satisfied only by the Trustee's receipt of a
representation letter from the transferee substantially in the form of Exhibit
K or Exhibit L or, if such Certificate is a Residual Certificate, such
requirement is satisfied only by the Trustee's receipt of a representation
letter from the transferee substantially in the form of Exhibit I), to the
effect that (x) such transferee is not an employee benefit plan or arrangement
subject to Section 406 of ERISA or a plan or arrangement subject to Section
4975 of the Code, or a Person acting on behalf of any such plan or arrangement
or using the assets of any such plan or arrangement, or (ii) in the case of an
ERISA-Restricted Certificate that has been the subject of an ERISA-Qualifying
Underwriting, a representation that the transferee is an insurance company
which is purchasing such Certificate with funds contained in an "insurance
company general account" (as such term is defined in Section V(e) of
Prohibited Transaction Class Exemption 95-60 ("PTCE 95-60")) and that the
purchase and holding of such Certificate satisfy the requirements for
exemptive relief under Sections I and III of PTCE 95-60 or (iii) in the case
of any ERISA-Restricted Certificate presented for registration in the name of
an employee benefit plan or arrangement subject to ERISA, or a plan or
arrangement subject to Section 4975 of the Code (or comparable provisions of
any subsequent enactments), or a trustee of any such plan or arrangement or
any other person acting on behalf of any such plan or arrangement, an Opinion
of Counsel satisfactory to the Trustee and addressed to the Trustee and the
Master Servicer to the effect that the purchase and holding of such
ERISA-Restricted Certificate will not result in a non-exempt prohibited
transaction under ERISA or the Code and will not subject the Trustee or the
Master Servicer to any obligation in addition to those expressly undertaken in
this Agreement, which Opinion of Counsel shall not be an expense of the
Trustee or the Master Servicer. For purposes of the preceding sentence, one of
such representations, as appropriate, shall be deemed to have been made to the
Trustee by the transferee's acceptance of an ERISA-Restricted Certificate (or
the acceptance by a Certificate Owner of the beneficial interest in any such
Class of ERISA-Restricted Certificates) unless the Trustee shall have received
from the transferee an Opinion of Counsel as described in clause (ii) or a
representation acceptable in form and substance to the Trustee.
Notwithstanding anything else to the contrary herein, any purported transfer
of an ERISA-Restricted Certificate to or on behalf of an employee benefit plan
subject to Section 406 of ERISA or a plan subject to Section 4975 of the Code
without the delivery to the Trustee and the Master Servicer of an Opinion of
Counsel satisfactory to the Trustee and the Master Servicer as described above
and meeting the requirements of clause (i) of the first sentence of this
paragraph as described above shall be void and of no effect. The Trustee shall
be under no liability to any Person for any registration of transfer of any
ERISA-Restricted Certificate that is in fact not permitted by this Section
5.02(b) or for making any payments due on such Certificate to the Holder
thereof or taking any other action with respect to such Holder under the
provisions of this Agreement so long as the Trustee, with respect to the
transfer of such Classes of Certificates, required delivery of such
certificates and other documentation or evidence as are expressly required by
the terms of this Agreement and examined such certificates and other
documentation or evidence to determine compliance as to form with the express
requirements hereof. The Trustee shall be entitled, but not obligated, to

                                     -92-
<PAGE>

recover from any Holder of any ERISA-Restricted Certificate that was in fact
an employee benefit plan or arrangement subject to Section 406 of ERISA or a
plan or arrangement subject to Section 4975 of the Code or a Person acting on
behalf of any such plan or arrangement at the time it became a Holder or, at
such subsequent time as it became such a plan or arrangement or Person acting
on behalf of such a plan or arrangement, all payments made on such
ERISA-Restricted Certificate at and after either such time. Any such payments
so recovered by the Trustee shall be paid and delivered by the Trustee to the
last preceding Holder of such Certificate that is not such a plan or
arrangement or Person acting on behalf of a plan or arrangement.

          (c) Each Person who has or who acquires any Ownership Interest in a
Class A-R Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the following provisions, and
the rights of each Person acquiring any Ownership Interest in a Class A-R
Certificate are expressly subject to the following provisions:

               (i) Each Person holding or acquiring any Ownership Interest in
     a Class A-R Certificate shall be a Permitted Transferee and shall
     promptly notify the Trustee of any change or impending change in its
     status as a Permitted Transferee.

               (ii) No Ownership Interest in a Class A-R Certificate may be
     registered on the Closing Date or thereafter transferred, and the Trustee
     shall not register the Transfer of any Class A-R Certificate unless, the
     Trustee shall have been furnished with an affidavit (a "Transfer
     Affidavit") of the initial owner or the proposed transferee in the form
     attached hereto as Exhibit I.

               (iii) Each Person holding or acquiring any Ownership Interest
     in a Class A-R Certificate shall agree (A) to obtain a Transfer Affidavit
     from any other Person to whom such Person attempts to Transfer its
     Ownership Interest in a Class A-R Certificate, (B) to obtain a Transfer
     Affidavit from any Person for whom such Person is acting as nominee,
     trustee or agent in connection with any Transfer of a Class A-R
     Certificate and (C) not to Transfer its Ownership Interest in a Class A-R
     Certificate, or to cause the Transfer of an Ownership Interest in a Class
     A-R Certificate to any other Person, if it has actual knowledge that such
     Person is not a Permitted Transferee or that such Transfer Affidavit is
     false.

               (iv) Any attempted or purported Transfer of any Ownership
     Interest in a Class A-R Certificate in violation of the provisions of
     this Section 5.02(c) shall be absolutely null and void and shall vest no
     rights in the purported Transferee. If any purported transferee shall
     become a Holder of a Class A-R Certificate in violation of the provisions
     of this Section 5.02(c), then the last preceding Permitted Transferee
     shall be restored to all rights as Holder thereof retroactive to the date
     of registration of Transfer of such Class A-R Certificate. The Trustee
     shall be under no liability to any Person for any registration of
     Transfer of a Class A-R Certificate that is in fact not permitted by
     Section 5.02(b) and this Section 5.02(c) or for making any payments due
     on such Certificate to the Holder thereof or taking any other action with
     respect to such Holder under the provisions of this Agreement so long as
     the Transfer was registered after receipt of the related Transfer
     Affidavit and Transferor Certificate. The Trustee shall be entitled but
     not obligated to recover from any Holder of a Class A-R Certificate that
     was in fact not a

                                     -93-
<PAGE>

     Permitted Transferee at the time it became a Holder or, at such
     subsequent time as it became other than a Permitted Transferee, all
     payments made on such Class A-R Certificate at and after either such
     time. Any such payments so recovered by the Trustee shall be paid and
     delivered by the Trustee to the last preceding Permitted Transferee of
     such Certificate.

               (v) The Master Servicer shall use its best efforts to make
     available, upon receipt of written request from the Trustee, all
     information necessary to compute any tax imposed under section 860E(e) of
     the Code as a result of a Transfer of an Ownership Interest in a Class
     A-R Certificate to any Holder who is not a Permitted Transferee.

          The restrictions on Transfers of a Class A-R Certificate set forth
in this Section 5.02(c) shall cease to apply (and the applicable portions of
the legend on a Class A-R Certificate may be deleted) with respect to
Transfers occurring after delivery to the Trustee of an Opinion of Counsel,
which Opinion of Counsel shall not be an expense of the Trustee, the Seller or
the Master Servicer to the effect that the elimination of such restrictions
will not cause any REMIC formed hereunder to fail to qualify as a REMIC at any
time that the Certificates are outstanding or result in the imposition of any
tax on the Trust Fund, a Certificateholder or another Person. Each Person
holding or acquiring any Ownership Interest in a Class A-R Certificate, by
acceptance of its Ownership Interest, shall be deemed to consent to any
amendment of this Agreement that, based on an Opinion of Counsel furnished to
the Trustee, is reasonably necessary (a) to ensure that the record ownership
of, or any beneficial interest in, a Class A-R Certificate is not transferred,
directly or indirectly, to a Person that is not a Permitted Transferee and (b)
to provide for a means to compel the Transfer of a Class A-R Certificate that
is held by a Person that is not a Permitted Transferee to a Holder that is a
Permitted Transferee.

          The preparation and delivery of all affidavits, certifications and
opinions referred to above in this Section 5.02 shall not be an expense of the
Trust Fund, the Trustee, the Depositor, the Seller or the Master Servicer.

          Section 5.03 Mutilated, Destroyed, Lost or Stolen Certificates.

          If (a) any mutilated Certificate is surrendered to the Trustee, or
the Trustee receives evidence to its satisfaction of the destruction, loss or
theft of any Certificate and of the ownership thereof and (b) there is
delivered to the Master Servicer and the Trustee such security or indemnity as
may be required by them to save each of them harmless, then, in the absence of
notice to the Trustee that such Certificate has been acquired by a bona fide
purchaser, the Trustee shall execute, authenticate and deliver, in exchange
for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a
new Certificate of like Class, tenor and Percentage Interest. In connection
with the issuance of any new Certificate under this Section 5.03, the Trustee
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.
Any replacement Certificate issued pursuant to this Section 5.03 shall
constitute complete and indefeasible evidence of ownership in the Trust Fund,
as if originally issued, whether or not the lost, stolen or destroyed
Certificate shall be found at any time. All Certificates surrendered to the
Trustee under the terms of this Section 5.03 shall be

                                     -94-

canceled and destroyed by the Trustee in accordance with its standard
procedures without liability on its part.

          Section 5.04 Persons Deemed Owners.

          The Master Servicer, the Trustee and any agent of the Master
Servicer or the Trustee may treat the person in whose name any Certificate is
registered as the owner of such Certificate for the purpose of receiving
distributions as provided in this Agreement and for all other purposes
whatsoever, and neither the Master Servicer, the Trustee nor any agent of the
Master Servicer or the Trustee shall be affected by any notice to the
contrary.

          Section 5.05 Access to List of Certificateholders' Names and
                       Addresses.

          If three or more Certificateholders and/or Certificate Owners (a)
request such information in writing from the Trustee, (b) state that such
Certificateholders and/or Certificate Owners desire to communicate with other
Certificateholders and/or Certificate Owners with respect to their rights
under this Agreement or under the Certificates, and (c) provide a copy of the
communication that such Certificateholders and/or Certificate Owners propose
to transmit or if the Depositor or Master Servicer shall request such
information in writing from the Trustee, then the Trustee shall, within ten
Business Days after the receipt of such request, provide the Depositor, the
Master Servicer or such Certificateholders and/or Certificate Owners at such
recipients' expense the most recent list of the Certificateholders and/or
Certificate Owners of the Trust Fund held by the Trustee, if any. The
Depositor and every Certificateholder and/or Certificate Owner , by receiving
and holding a Certificate, agree that the Trustee shall not be held
accountable by reason of the disclosure of any such information as to the list
of the Certificateholders and/or Certificate Owners hereunder, regardless of
the source from which such information was derived.

          Section 5.06 Book-Entry Certificates.

          The Book-Entry Certificates, upon original issuance, shall be issued
in the form of one or more typewritten Certificates for each Class of such
Certificates, to be delivered to the Depository by or on behalf of the
Depositor. Such Certificates shall initially be registered on the Certificate
Register in the name of the Depository or its nominee, and no Certificate
Owner of such Certificates will receive a definitive certificate representing
such Certificate Owner's interest in such Certificates, except as provided in
Section 5.08. Unless and until definitive, fully registered Certificates
("Definitive Certificates") have been issued to the Certificate Owners of such
Certificates pursuant to Section 5.08:

          (a) the provisions of this Section shall be in full force and
effect;

          (b) the Depositor, the Seller, the Master Servicer and the Trustee
may deal with the Depository and the Depository Participants for all purposes
(including the making of distributions) as the authorized representative of
the respective Certificate Owners of such Certificates;

          (c) registration of the Book-Entry Certificates may not be
transferred by the Trustee except to another Depository;

                                     -95-
<PAGE>

          (d) the rights of the respective Certificate Owners of such
Certificates shall be exercised only through the Depository and the Depository
Participants and shall be limited to those established by law and agreements
between the Owners of such Certificates and the Depository and/or the
Depository Participants. Pursuant to the Depository Agreement, unless and
until Definitive Certificates are issued pursuant to Section 5.08, the
Depository will make book-entry transfers among the Depository Participants
and receive and transmit distributions of principal and interest on the
related Certificates to such Depository Participants;

          (e) the Depository may collect its usual and customary fees, charges
and expenses from its Depository Participants;

          (f) the Trustee may rely and shall be fully protected in relying
upon information furnished by the Depository with respect to its Depository
Participants; and

          (g) to the extent that the provisions of this Section conflict with
any other provisions of this Agreement, the provisions of this Section shall
control.

          For purposes of any provision of this Agreement requiring or
permitting actions with the consent of, or at the direction of,
Certificateholders evidencing a specified percentage of the aggregate unpaid
principal amount of any Class of Certificates, such direction or consent may
be given by Certificate Owners (acting through the Depository and the
Depository Participants) owning Book-Entry Certificates evidencing the
requisite percentage of principal amount of such Class of Certificates.

          Section 5.07 Notices to Depository.

          Whenever any notice or other communication is required to be given
to Certificateholders of the Class with respect to which Book-Entry
Certificates have been issued, unless and until Definitive Certificates shall
have been issued to the related Certificate Owners, the Trustee shall give all
such notices and communications to the Depository.

          Section 5.08 Definitive Certificates.

          If, after Book-Entry Certificates have been issued with respect to
any Certificates, (a) the Depositor advises the Trustee that the Depository is
no longer willing or able to discharge properly its responsibilities under the
Depository Agreement with respect to such Certificates and the Trustee or the
Depositor is unable to locate a qualified successor, or (b) after the
occurrence and continuation of an Event of Default, Certificate Owners of such
Book-Entry Certificates having not less than 51% of the Voting Rights
evidenced by any Class of Book-Entry Certificates advise the Trustee and the
Depository in writing through the Depository Participants that the
continuation of a book-entry system with respect to Certificates of such Class
through the Depository (or its successor) is no longer in the best interests
of the Certificate Owners of such Class, then the Trustee shall notify all
Certificate Owners of such Certificates, through the Depository, of the
occurrence of any such event and of the availability of Definitive
Certificates to Certificate Owners of such Class requesting the same. The
Depositor shall provide the Trustee with an adequate inventory of certificates
to facilitate the issuance and transfer of Definitive Certificates. Upon
surrender to the Trustee of any such Certificates by the Depository,
accompanied by registration instructions from the Depository for registration,
the

                                     -96-
<PAGE>

Trustee shall authenticate and deliver such Definitive Certificates. Neither
the Depositor nor the Trustee shall be liable for any delay in delivery of
such instructions and each may conclusively rely on, and shall be protected in
relying on, such instructions. Upon the issuance of such Definitive
Certificates, all references herein to obligations imposed upon or to be
performed by the Depository shall be deemed to be imposed upon and performed
by the Trustee, to the extent applicable with respect to such Definitive
Certificates and the Trustee shall recognize the Holders of such Definitive
Certificates as Certificateholders hereunder.

          Section 5.09 Maintenance of Office or Agency.

          The Trustee will maintain or cause to be maintained at its expense
an office or offices or agency or agencies in New York City where Certificates
may be surrendered for registration of transfer or exchange. The Trustee
initially designates its offices at 101 Barclay Street, New York, New York
10286, Attention: Corporate Trust MBS Administration, as offices for such
purposes. The Trustee will give prompt written notice to the
Certificateholders of any change in such location of any such office or
agency.

               THE DEPOSITOR, THE MASTER SERVICER AND THE SELLER

          Section 6.01 Respective Liabilities of the Depositor, the Master
                       Servicer and the Seller.

          The Depositor, the Master Servicer and the Seller shall each be
liable in accordance herewith only to the extent of the obligations
specifically and respectively imposed upon and undertaken by them herein.

          Section 6.02 Merger or Consolidation of the Depositor, the Master
                       Servicer or the Seller.

          The Depositor will keep in full effect its existence, rights and
franchises as a corporation under the laws of the United States or under the
laws of one of the states thereof and will each obtain and preserve its
qualification to do business as a foreign corporation in each jurisdiction in
which such qualification is or shall be necessary to protect the validity and
enforceability of this Agreement, or any of the Mortgage Loans and to perform
its duties under this Agreement. The Master Servicer will keep in effect its
existence, rights and franchises as a limited partnership under the laws of
the United States or under the laws of one of the states thereof and will
obtain and preserve its qualification or registration to do business as a
foreign partnership in each jurisdiction in which such qualification or
registration is or shall be necessary to protect the validity and
enforceability of this Agreement or any of the Mortgage Loans and to perform
its duties under this Agreement.

          Any Person into which the Depositor, the Master Servicer or the
Seller may be merged or consolidated, or any Person resulting from any merger
or consolidation to which the Depositor, the Master Servicer or the Seller
shall be a party, or any person succeeding to the business of the Depositor,
the Master Servicer or the Seller, shall be the successor of the Depositor,
the Master Servicer or the Seller, as the case may be, hereunder, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, anything herein to the contrary notwithstanding; provided that
the successor or surviving Person to the Master Servicer shall be qualified to
service mortgage loans on behalf of, Fannie Mae or Freddie Mac.

          Section 6.03 Limitation on Liability of the Depositor, the Seller,
                       the Master Servicer and Others.

          None of the Depositor, the Seller, the Master Servicer or any of the
directors, officers, employees or agents of the Depositor, the Seller or the
Master Servicer shall be under any liability to the Trustee (except as
provided in Section 8.05), the Trust Fund or the Certificateholders for any
action taken or for refraining from the taking of any action in good faith
pursuant to this Agreement, or for errors in judgment; provided that this
provision shall not protect the Depositor, the Seller, the Master Servicer or
any such Person against any breach of representations or warranties made by it
herein or protect the Depositor, the Seller, the Master Servicer or any such
Person from any liability that would otherwise be imposed by reasons of

                                     -98-
<PAGE>

willful misfeasance, bad faith or gross negligence in the performance of
duties or by reason of reckless disregard of obligations and duties hereunder.
The Depositor, the Seller, the Master Servicer and any director, officer,
employee or agent of the Depositor, the Seller or the Master Servicer may rely
in good faith on any document of any kind prima facie properly executed and
submitted by any Person respecting any matters arising hereunder. The
Depositor, the Seller, the Master Servicer and any director, officer, employee
or agent of the Depositor, the Seller or the Master Servicer shall be
indemnified by the Trust Fund and held harmless against any loss, liability or
expense incurred in connection with any audit, controversy or judicial
proceeding relating to a governmental taxing authority or any legal action
relating to this Agreement or the Certificates, other than any loss, liability
or expense related to any specific Mortgage Loan or Mortgage Loans (except as
any such loss, liability or expense shall be otherwise reimbursable pursuant
to this Agreement) and any loss, liability or expense incurred by reason of
willful misfeasance, bad faith or gross negligence in the performance of
duties hereunder or by reason of reckless disregard of obligations and duties
hereunder. None of the Depositor, the Seller or the Master Servicer shall be
under any obligation to appear in, prosecute or defend any legal action that
is not incidental to its respective duties hereunder and that in its opinion
may involve it in any expense or liability; provided that any of the
Depositor, the Seller or the Master Servicer may, in its discretion undertake
any such action that it may deem necessary or desirable in respect of this
Agreement and the rights and duties of the parties hereto and interests of the
Trustee and the Certificateholders hereunder. In such event, the legal
expenses and costs of such action and any liability resulting therefrom shall
be, expenses, costs and liabilities of the Trust Fund, and the Depositor, the
Seller and the Master Servicer shall be entitled to be reimbursed therefor out
of the Certificate Account as provided by Section 3.08 hereof.

          Section 6.04 Limitation on Resignation of Master Servicer.

          The Master Servicer shall not resign from the obligations and duties
hereby imposed on it except (i) upon determination that its duties hereunder
are no longer permissible under applicable law or (ii) upon appointment of a
successor servicer that is reasonably acceptable to the Trustee and the Loan
Insurance Provider and written confirmation from each Rating Agency (which
confirmation shall be furnished to the Depositor and the Trustee) that such
resignation will not cause such Rating Agency to reduce the then current
rating of the Certificates. Any such determination pursuant to clause (i) of
the preceding sentence permitting the resignation of the Master Servicer shall
be evidenced by an Opinion of Counsel to such effect delivered to the Trustee.
No resignation of the Master Servicer shall become effective until the Trustee
or a successor servicer to such appointment shall have assumed the Master
Servicer's responsibilities, duties, liabilities (other than those liabilities
arising prior to the appointment of such successor) and obligations under this
Agreement.

          Section 6.05 Errors and Omissions Insurance; Fidelity Bonds.

          The Master Servicer shall, for so long as it acts as servicer under
this Agreement, obtain and maintain in force (a) a policy or policies of
insurance covering errors and omissions in the performance of its obligations
as servicer hereunder, and (b) a fidelity bond in respect of its officers,
employees and agents. Each such policy or policies and bond shall, together,
comply with the requirements from time to time of Fannie Mae or Freddie Mac
for persons performing servicing for mortgage loans purchased by Fannie Mae or
Freddie Mac. In the event that any

                                     -99-
<PAGE>

such policy or bond ceases to be in effect, the Master Servicer shall use its
reasonable best efforts to obtain a comparable replacement policy or bond from
an insurer or issuer, meeting the requirements set forth above as of the date
of such replacement.

          The Master Servicer shall provide the Trustee (upon such party's
reasonable request) with copies of any such insurance policies and fidelity
bond. The Master Servicer shall be deemed to have complied with this provision
if an Affiliate of the Master Servicer has such errors and omissions and
fidelity bond coverage and, by the terms of such insurance policy or fidelity
bond, the coverage afforded thereunder extends to the Master Servicer.

                    DEFAULT; TERMINATION OF MASTER SERVICER

          Section 7.01 Events of Default.

          "Event of Default," wherever used herein, means any one of the
following events:

               (i) any failure by the Master Servicer to deposit in the
     Certificate Account or the Distribution Account or remit to the Trustee
     any payment (excluding a payment required to be made under Section 4.01
     hereof) required to be made under the terms of this Agreement, which
     failure shall continue unremedied for five calendar days and, with
     respect to a payment required to be made under Section 4.01(b) or (c)
     hereof, for one Business Day, after the date on which written notice of
     such failure shall have been given to the Master Servicer by the Trustee
     or the Depositor, or to the Trustee and the Master Servicer by the
     Holders of Certificates evidencing not less than 25% of the Voting Rights
     evidenced by the Certificates; or

               (ii) any failure by the Master Servicer to observe or perform
     in any material respect any other of the covenants or agreements on the
     part of the Master Servicer contained in this Agreement or any
     representation or warranty shall prove to be untrue, which failure or
     breach shall continue unremedied for a period of 60 days after the date
     on which written notice of such failure shall have been given to the
     Master Servicer by the Trustee or the Depositor, or to the Trustee by the
     Holders of Certificates evidencing not less than 25% of the Voting Rights
     evidenced by the Certificates; provided that the sixty-day cure period
     shall not apply to the initial delivery of the Mortgage File for Delay
     Delivery Mortgage Loans nor the failure to repurchase or substitute in
     lieu thereof; or

               (iii) a decree or order of a court or agency or supervisory
     authority having jurisdiction in the premises for the appointment of a
     receiver or liquidator in any insolvency, readjustment of debt,
     marshalling of assets and liabilities or similar proceedings, or for the
     winding-up or liquidation of its affairs, shall have been entered against
     the Master Servicer and such decree or order shall have remained in force
     undischarged or unstayed for a period of 60 consecutive days; or

               (iv) the Master Servicer shall consent to the appointment of a
     receiver or liquidator in any insolvency, readjustment of debt,
     marshalling of assets and liabilities or similar proceedings of or
     relating to the Master Servicer or all or substantially all of the
     property of the Master Servicer; or

               (v) the Master Servicer shall admit in writing its inability to
     pay its debts generally as they become due, file a petition to take
     advantage of, or commence a voluntary case under, any applicable
     insolvency or reorganization statute, make an assignment for the benefit
     of its creditors, or voluntarily suspend payment of its obligations.

                                    -101-
<PAGE>

          If an Event of Default shall occur, then, and in each and every such
case, so long as such Event of Default shall not have been remedied, the
Trustee shall, but only at the direction of the Holders of Certificates
evidencing not less than 25% of the Voting Rights evidenced by the
Certificates, by notice in writing to the Master Servicer (with a copy to each
Rating Agency), terminate all of the rights and obligations of the Master
Servicer under this Agreement and in and to the Mortgage Loans and the
proceeds thereof, other than its rights as a Certificateholder hereunder. On
or after the receipt by the Master Servicer of such written notice, all
authority and power of the Master Servicer hereunder, whether with respect to
the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee.
The Trustee shall thereupon make any Advance described in Section 4.01 hereof
subject to Section 3.04 hereof. The Trustee is hereby authorized and empowered
to execute and deliver, on behalf of the Master Servicer, as attorney-in-fact
or otherwise, any and all documents and other instruments, and to do or
accomplish all other acts or things necessary or appropriate to effect the
purposes of such notice of termination, whether to complete the transfer and
endorsement or assignment of the Mortgage Loans and related documents, or
otherwise. Unless expressly provided in such written notice, no such
termination shall affect any obligation of the Master Servicer to pay amounts
owed pursuant to Article VIII. The Master Servicer agrees to cooperate with
the Trustee in effecting the termination of the Master Servicer's
responsibilities and rights hereunder, including, without limitation, the
transfer to the Trustee of all cash amounts which shall at the time be
credited to the Certificate Account, or thereafter be received with respect to
the Mortgage Loans. The Trustee shall promptly notify the Rating Agencies of
the occurrence of an Event of Default.

          Notwithstanding any termination of the activities of a Master
Servicer hereunder, such Master Servicer shall be entitled to receive, out of
any late collection of a Scheduled Payment on a Mortgage Loan that was due
prior to the notice terminating such Master Servicer's rights and obligations
as Master Servicer hereunder and received after such notice, that portion
thereof to which such Master Servicer would have been entitled pursuant to
Sections 3.08(a)(i) through (viii), and any other amounts payable to such
Master Servicer hereunder the entitlement to which arose prior to the
termination of its activities hereunder.

          Section 7.02 Trustee to Act; Appointment of Successor.

          On and after the time the Master Servicer receives a notice of
termination pursuant to Section 7.01 hereof, the Trustee shall, to the extent
provided in Section 3.04, be the successor to the Master Servicer in its
capacity as servicer under this Agreement and the transactions set forth or
provided for herein and shall be subject to all the responsibilities, duties
and liabilities relating thereto placed on the Master Servicer by the terms
and provisions hereof and applicable law including the obligation to make
advances pursuant to Section 4.01. As compensation therefor, the Trustee shall
be entitled to all fees, costs and expenses relating to the Mortgage Loans
that the Master Servicer would have been entitled to if the Master Servicer
had continued to act hereunder. Notwithstanding the foregoing, if the Trustee
has become the successor to the Master Servicer in accordance with Section
7.01 hereof, the Trustee may, if it shall be unwilling to so act, or shall, if
it is prohibited by applicable law from making Advances pursuant to Section
4.01 hereof or if it is otherwise unable to so act, appoint, or petition a
court of competent jurisdiction to appoint, any established mortgage loan
servicing institution the appointment of which does not adversely affect the
then current rating of the Certificates by each Rating Agency as the successor
to the Master Servicer hereunder in the assumption of all or any

                                    -102-
<PAGE>

part of the responsibilities, duties or liabilities of the Master Servicer
hereunder. Any successor Master Servicer shall be an institution that is a
Fannie Mae and Freddie Mac approved seller/servicer in good standing, that has
a net worth of at least $15,000,000, and that is willing to service the
Mortgage Loans and executes and delivers to the Depositor and the Trustee an
agreement accepting such delegation and assignment, that contains an
assumption by such Person of the rights, powers, duties, responsibilities,
obligations and liabilities of the Master Servicer (other than liabilities and
indemnities of the Master Servicer under Section 6.03 hereof incurred prior to
termination of the Master Servicer under Section 7.01), with like effect as if
originally named as a party to this Agreement; and provided further that each
Rating Agency acknowledges that its rating of the Certificates in effect
immediately prior to such assignment and delegation will not be qualified or
reduced as a result of such assignment and delegation. No appointment of a
successor to the Master Servicer hereunder shall be effective until the
Trustee shall have consented thereto, and written notice of such proposed
appointment shall have been provided by the Trustee to each Certificateholder.
No successor to the Master Servicer shall be appointed hereunder unless the
appointment of such institution as successor Master Servicer shall not
adversely affect the coverage under the Loan Insurance Policy. The Trustee
shall not resign as servicer until a successor servicer has been appointed and
has accepted such appointment. Pending appointment of a successor to the
Master Servicer hereunder, the Trustee, unless the Trustee is prohibited by
law from so acting, shall, subject to Section 3.04 hereof, act in such
capacity as hereinabove provided. In connection with such appointment and
assumption, the Trustee may make such arrangements for the compensation of
such successor out of payments on Mortgage Loans as it and such successor
shall agree; provided that no such compensation shall be in excess of that
permitted the Master Servicer hereunder. The Trustee and such successor shall
take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession. Neither the Trustee nor any other successor
servicer shall be deemed to be in default hereunder by reason of any failure
to make, or any delay in making, any distribution hereunder or any portion
thereof or any failure to perform, or any delay in performing, any duties or
responsibilities hereunder, in either case caused by the failure of the Master
Servicer to deliver or provide, or any delay in delivering or providing, any
cash, information, documents or records to it.

          Any successor to the Master Servicer as servicer shall give notice
to the Mortgagors of such change of servicer and shall, during the term of its
service as servicer, maintain in force the policy or policies that the Master
Servicer is required to maintain pursuant to Section 6.05.

          In connection with the termination or resignation of the Master
Servicer hereunder, either (i) the successor Master Servicer, including the
Trustee if the Trustee is acting as successor Master Servicer, shall represent
and warrant that it is a member of MERS in good standing and shall agree to
comply in all material respects with the rules and procedures of MERS in
connection with the servicing of the Mortgage Loans that are registered with
MERS, or (ii) the predecessor Master Servicer shall cooperate with the
successor Master Servicer in causing MERS to execute and deliver an assignment
of Mortgage in recordable form to transfer the Mortgage from MERS to the
Trustee and to execute and deliver such other notices, documents and other
instruments as may be necessary or desirable to effect a transfer of such
Mortgage Loan or servicing of such Mortgage Loan on the MERS(R) System to the
successor Master Servicer. The predecessor Master Servicer shall file or cause
to be filed any such

                                    -103-
<PAGE>

assignment in the appropriate recording office. The successor Master Servicer
shall cause such assignment to be delivered to the Trustee or the Custodian
promptly upon receipt of the original with evidence of recording thereon or a
copy certified by the public recording office in which such assignment was
recorded.

          Section 7.03 Notification to Certificateholders.

          (a) Upon any termination of or appointment of a successor to the
Master Servicer, the Trustee shall give prompt written notice thereof to
Certificateholders and to each Rating Agency.

          (b) Within 60 days after the occurrence of any Event of Default, the
Trustee shall transmit by mail to all Certificateholders notice of each such
Event of Default hereunder known to the Trustee, unless such Event of Default
shall have been cured or waived.

                   CONCERNING THE TRUSTEE AND THE CO-TRUSTEE

          Section 8.01 Duties of Trustee.

          The Trustee, prior to the occurrence of an Event of Default and
after the curing of all Events of Default that may have occurred, shall
undertake to perform such duties and only such duties as are specifically set
forth in this Agreement. In case an Event of Default has occurred and remains
uncured, the Trustee shall exercise such of the rights and powers vested in it
by this Agreement, and use the same degree of care and skill in their exercise
as a prudent person would exercise or use under the circumstances in the
conduct of such person's own affairs.

          The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments
furnished to the Trustee (or the Co-Trustee, to the extent provided in this
Agreement) that are specifically required to be furnished pursuant to any
provision of this Agreement shall examine them to determine whether they
conform to the requirements of this Agreement, to the extent provided in this
Agreement. If any such instrument is found not to conform to the requirements
of this Agreement in a material manner, the Trustee shall take action as it
deems appropriate to have the instrument corrected.

          No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own grossly negligent action, its own gross
negligent failure to act or its own misconduct, its grossly negligent failure
to perform its obligations in compliance with this Agreement, or any liability
that would be imposed by reason of its willful misfeasance or bad faith;
provided that:

               (i) prior to the occurrence of an Event of Default, and after
     the curing of all such Events of Default that may have occurred, the
     duties and obligations of the Trustee shall be determined solely by the
     express provisions of this Agreement, the Trustee shall not be liable,
     individually or as Trustee, except for the performance of such duties and
     obligations as are specifically set forth in this Agreement, no implied
     covenants or obligations shall be read into this Agreement against the
     Trustee and the Trustee may conclusively rely, as to the truth of the
     statements and the correctness of the opinions expressed therein, upon
     any certificates or opinions furnished to the Trustee and conforming to
     the requirements of this Agreement that it reasonably believed in good
     faith to be genuine and to have been duly executed by the proper

               (ii) the Trustee shall not be liable, individually or as
     Trustee, for an error of judgment made in good faith by a Responsible
     Officer or Responsible Officers of the Trustee, unless the Trustee was
     grossly negligent or acted in bad faith or with willful misfeasance;

               (iii) the Trustee shall not be liable, individually or as
     Trustee, with respect to any action taken, suffered or omitted to be
     taken by it in good faith in accordance with

     the direction of Holders of each Class of Certificates evidencing not
     less than 25% of the Voting Rights of such Class relating to the time,
     method and place of conducting any proceeding for any remedy available to
     the Trustee, or exercising any trust or power conferred upon the Trustee
     under this Agreement; and

               (iv) without in any way limiting the provisions of this Section
     8.01 or Section 8.02 hereof, the Trustee shall be entitled to rely
     conclusively on the information delivered to it by the Master Servicer in
     a Trustee Advance Notice in determining whether or not it is required to
     make an Advance under Section 4.01(d), shall have no responsibility to
     ascertain or confirm any information contained in any Trustee Advance
     Notice, and shall have no obligation to make any Advance under Section
     4.01(d) in the absence of a Trustee Advance Notice or actual knowledge by
     a Responsible Officer that a (A) required Advance was not made and (B)
     such required Advance was not a Nonrecoverable Advance.

          Section 8.02 Certain Matters Affecting the Trustee.

          (a) Except as otherwise provided in Section 8.01:

               (i) the Trustee may request and rely upon and shall be
     protected in acting or refraining from acting upon any resolution,
     Officer's Certificate, certificate of auditors or any other certificate,
     statement, instrument, opinion, report, notice, request, consent, order,
     appraisal, bond or other paper or document believed by it to be genuine
     and to have been signed or presented by the proper party or parties;

               (ii) the Trustee may consult with counsel and any Opinion of
     Counsel shall be full and complete authorization and protection in
     respect of any action taken or suffered or omitted by it hereunder in
     good faith and in accordance with such Opinion of Counsel;

               (iii) the Trustee shall not be liable, individually or as
     Trustee, for any action taken, suffered or omitted by it in good faith
     and believed by it to be authorized or within the discretion or rights or
     powers conferred upon it by this Agreement;

               (iv) prior to the occurrence of an Event of Default hereunder
     and after the curing of all Events of Default that may have occurred, the
     Trustee shall not be bound to make any investigation into the facts or
     matters stated in any resolution, certificate, statement, instrument,
     opinion, report, notice, request, consent, order, approval, bond or other
     paper or document, unless requested in writing so to do by the Holders of
     each Class of Certificates evidencing not less than 25% of the Voting
     Rights of such Class; provided, however, that if the payment within a
     reasonable time to the Trustee of the costs, expenses or liabilities
     likely to be incurred by it in the making of such investigation is, in
     the opinion of the Trustee not reasonably assured to the Trustee by such
     Certificateholders, the Trustee may require reasonable indemnity against
     such cost, expense or liability from such Certificateholders as a
     condition to taking any such action;

                                    -106-
<PAGE>

               (v) the Trustee may execute any of the trusts or powers
     hereunder or perform any duties hereunder either directly or by or
     through agents, accountants or attorneys;

               (vi) the Trustee shall not be required to expend its own funds
     or otherwise incur any financial liability in the performance of any of
     its duties hereunder if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against such liability
     is not assured to it;

               (vii) the Trustee shall not be liable, individually or as
     Trustee, for any loss on any investment of funds pursuant to this
     Agreement (other than as issuer of the investment security);

               (viii) the Trustee shall not be deemed to have knowledge of an
     Event of Default until a Responsible Officer of the Trustee shall have
     received written notice thereof; and

               (ix) the Trustee shall be under no obligation to exercise any
     of the trusts or powers vested in it by this Agreement or to make any
     investigation of matters arising hereunder or to institute, conduct or
     defend any litigation hereunder or in relation hereto at the request,
     order or direction of any of the Certificateholders, pursuant to the
     provisions of this Agreement, unless such Certificateholders shall have
     offered to the Trustee reasonable security or indemnity against the
     costs, expenses and liabilities that may be incurred therein or thereby.

          (b) All rights of action under this Agreement or under any of the
Certificates, enforceable by the Trustee, may be enforced by the Trustee
without the possession of any of the Certificates, or the production thereof
at the trial or other proceeding relating thereto, and any such suit, action
or proceeding instituted by the Trustee shall be brought in its name for the
benefit of all the Holders of the Certificates, subject to the provisions of
this Agreement.

          Section 8.03 Trustee Not Liable for Mortgage Loans.

          The recitals contained herein shall be taken as the statements of
the Depositor or the Master Servicer, as the case may be, and the Trustee
assumes no responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Agreement or of any
Mortgage Loan or related document or of MERS or the MERS(R) System other than
with respect to the Trustee's execution and authentication of the
Certificates. The Trustee shall not be accountable for the use or application
by the Depositor or the Master Servicer of any funds paid to the Depositor or
the Master Servicer in respect of the Mortgage Loans or deposited in or
withdrawn from the Certificate Account by the Depositor or the Master
Servicer.

          Section 8.04 Trustee May Own Certificates.

          Section 8.05 Master Servicer to Pay Trustee's Fees and Expenses.

          The Master Servicer covenants and agrees to pay or reimburse the
Trustee, upon its request, for all reasonable expenses, disbursements and
advances incurred or made by the Trustee on behalf of the Trust Fund in
accordance with any of the provisions of this Agreement (including, without
limitation: (A) the reasonable compensation and the expenses and disbursements
of its counsel, but only for representation of the Trustee acting in its
capacity as Trustee hereunder and (B) to the extent that the Trustee must
engage persons not regularly in its employ to perform acts or services on
behalf of the Trust Fund, which acts or services are not in the ordinary
course of the duties of a trustee, paying agent or certificate registrar, in
the absence of a breach or default by any party hereto, the reasonable
compensation, expenses and disbursements of such persons, except any such
expense, disbursement or advance as may arise from its negligence, bad faith
or willful misconduct). The Trustee and any director, officer, employee or
agent of the Trustee shall be indemnified by the Master Servicer and held
harmless against any loss, liability or expense (i) incurred in connection
with any legal action relating to this Agreement or the Certificates, or in
connection with the performance of any of the Trustee's duties hereunder,
other than any loss, liability or expense incurred by reason of willful
misfeasance, bad faith or negligence in the performance of any of the
Trustee's duties hereunder or by reason of reckless disregard of the Trustee's
obligations and duties hereunder and (ii) resulting from any error in any tax
or information return prepared by the Master Servicer. Such indemnity shall
survive the termination of this Agreement or the resignation or removal of the
Trustee hereunder.

          Section 8.06 Eligibility Requirements for Trustee.

          The Trustee hereunder shall, at all times, be a corporation or
association organized and doing business under the laws of a state or the
United States of America, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus of at least $50,000,000,
subject to supervision or examination by federal or state authority and with a
credit rating that would not cause any of the Rating Agencies to reduce their
respective ratings of any Class of Certificates below the ratings issued on
the Closing Date (or having provided such security from time to time as is
sufficient to avoid such reduction). If such corporation or association
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 8.06 the combined capital and surplus of such
corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 8.06, the Trustee shall resign immediately in the
manner and with the effect specified in Section 8.07 hereof. The corporation
or national banking association serving as Trustee may have normal banking and
trust relationships with the Depositor, the Seller and the Master Servicer and
their respective affiliates; provided that such corporation cannot be an
affiliate of the Master Servicer other than the Trustee in its role as
successor to the Master Servicer.

          Section 8.07 Resignation and Removal of Trustee.

          The Trustee may at any time resign and be discharged from the trusts
hereby created by (1) giving written notice of resignation to the Depositor
and the Master Servicer and by mailing notice of resignation by first class
mail, postage prepaid, to the Certificateholders at their addresses appearing
on the Certificate Register and each Rating Agency, not less than 60 days
before the date specified in such notice when, subject to Section 8.08, such
resignation is to take effect, and (2) acceptance of appointment by a
successor Trustee in accordance with Section 8.08 and meeting the
qualifications set forth in Section 8.06. If no successor Trustee shall have
been so appointed and have accepted appointment within 30 days after the
giving of such notice or resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

          If at any time (i) the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.06 hereof and shall fail to resign
after written request thereto by the Depositor, (ii) the Trustee shall become
incapable of acting, or shall be adjudged as bankrupt or insolvent, or a
receiver of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, or
(iii)(A) a tax is imposed with respect to the Trust Fund by any state in which
the Trustee or the Trust Fund is located, (B) the imposition of such tax would
be avoided by the appointment of a different trustee and (C) the Trustee fails
to indemnify the Trust Fund against such tax, then the Depositor or the Master
Servicer may remove the Trustee and appoint a successor Trustee by written
instrument, in triplicate, one copy of which instrument shall be delivered to
the Trustee, one copy of which shall be delivered to the Master Servicer and
one copy of which shall be delivered to the successor Trustee.

          The Holders evidencing at least 51% of the Voting Rights of each
Class of Certificates may at any time remove the Trustee and appoint a
successor Trustee by written instrument or instruments, in triplicate, signed
by such Holders or their attorneys-in-fact duly authorized, one complete set
of which instruments shall be delivered by the successor Trustee to the Master
Servicer one complete set to the Trustee so removed and one complete set to
the successor so appointed. Notice of any removal of the Trustee shall be
given to each Rating Agency by the successor Trustee.

          Any resignation or removal of the Trustee and appointment of a
successor Trustee pursuant to any of the provisions of this Section 8.07 shall
become effective upon acceptance of appointment by the successor Trustee as
provided in Section 8.08 hereof.

          Section 8.08 Successor Trustee.

          Any successor Trustee appointed as provided in Section 8.07 hereof
shall execute, acknowledge and deliver to the Depositor, its predecessor
trustee and the Master Servicer an instrument accepting such appointment
hereunder and thereupon the resignation or removal of the predecessor trustee
shall become effective and such successor Trustee, without any further act,
deed or conveyance, shall become fully vested with all the rights, powers,
duties and obligations of its predecessor hereunder, with the like effect as
if originally named as trustee herein.

                                    -109-
<PAGE>

          No successor Trustee shall accept appointment as provided in this
Section 8.08 unless at the time of such acceptance such successor Trustee
shall be eligible under the provisions of Section 8.06 hereof and its
appointment shall not adversely affect the then current ratings of the
Certificates.

          Upon acceptance of appointment by a successor Trustee as provided in
this Section 8.08, the Depositor shall mail notice of the succession of such
trustee hereunder to all Holders of Certificates. If the Depositor fails to
mail such notice within ten days after acceptance of appointment by the
successor Trustee, the successor Trustee shall cause such notice to be mailed
at the expense of the Depositor.

          Section 8.09 Merger or Consolidation of Trustee.

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided that such corporation shall be eligible under the provisions of
Section 8.06 hereof without the execution or filing of any paper or further
act on the part of any of the parties hereto, anything herein to the contrary
notwithstanding.

          Section 8.10 Appointment of Co-Trustee or Separate Trustee.

          Notwithstanding any other provisions of this Agreement, at any time,
for the purpose of meeting any legal requirements of any jurisdiction in which
any part of the Trust Fund or property securing any Mortgage Note may at the
time be located, the Master Servicer and the Trustee acting jointly shall have
the power and shall execute and deliver all instruments to appoint one or more
Persons approved by the Trustee to act as co-trustee or co-trustees jointly
with the Trustee, or separate trustee or separate trustees, of all or any part
of the Trust Fund, and to vest in such Person or Persons, in such capacity and
for the benefit of the Certificateholders, such title to the Trust Fund or any
part thereof, whichever is applicable, and, subject to the other provisions of
this Section 8.10, such powers, duties, obligations, rights and trusts as the
Master Servicer and the Trustee may consider necessary or desirable. If the
Master Servicer shall not have joined in such appointment within 15 days after
receipt by it of a request to do so, or in the case an Event of Default shall
have occurred and be continuing, the Trustee alone shall have the power to
make such appointment. No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor Trustee under Section
8.06 and no notice to Certificateholders of the appointment of any co-trustee
or separate trustee shall be required under Section 8.08.

          Notwithstanding any provision of this Section 8.10 to the contrary,
the Co-Trustee appointed pursuant to Section 8.12(a) shall have no duties and
obligations hereunder other than those described in Section 8.12(a).

                                    -110-
<PAGE>

          Every separate trustee and co-trustee shall, to the extent permitted
by law, be appointed and act subject to the following provisions and
conditions:

               (i) All rights, powers, duties and obligations conferred or
     imposed upon the Trustee, except for the obligation of the Trustee under
     this Agreement to advance funds on behalf of the Master Servicer, shall
     be conferred or imposed upon and exercised or performed by the Trustee
     and such separate trustee or co-trustee (other than the Co-Trustee)
     jointly (it being understood that such separate trustee or co-trustee is
     not authorized to act separately without the Trustee joining in such
     act), except to the extent that under any law of any jurisdiction in
     which any particular act or acts are to be performed (whether as Trustee
     hereunder or as successor to the Master Servicer hereunder), the Trustee
     shall be incompetent or unqualified to perform such act or acts, in which
     event such rights, powers, duties and obligations (including the holding
     of title to the Trust Fund or any portion thereof in any such
     jurisdiction) shall be exercised and performed singly by such separate
     trustee or co-trustee (other than the Co-Trustee), but solely at the
     direction of the Trustee;

               (ii) No trustee hereunder shall be held personally liable by
     reason of any act or omission of any other trustee hereunder; and

               (iii) The Trustee may at any time accept the resignation of or
     remove any separate trustee or co-trustee.

          Except with respect to the Co-Trustee, any notice, request or other
writing given to the Trustee shall be deemed to have been given to each of the
then separate trustees and co-trustees, as effectively as if given to each of
them. Every instrument appointing any separate trustee or co-trustee shall
refer to this Agreement and the conditions of this Article VIII. Each separate
trustee and co-trustee, upon its acceptance of the trusts conferred, shall be
vested with the estates or property specified in its instrument of
appointment, either jointly with the Trustee or separately, as may be provided
therein, subject to all the provisions of this Agreement, specifically
including every provision of this Agreement relating to the conduct of,
affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee and a copy thereof given to
the Master Servicer and the Depositor.

          Any separate trustee or co-trustee (other than the Co-Trustee) may,
at any time, constitute the Trustee its agent or attorney-in-fact, with full
power and authority, to the extent not prohibited by law, to do any lawful act
under or in respect of this Agreement on its behalf and in its name. If any
separate trustee or co-trustee shall die, become incapable of acting, resign
or be removed, all of its estates, properties, rights, remedies and trusts
shall vest in and be exercised by the Trustee, to the extent permitted by law,
without the appointment of a new or successor Trustee.

          Section 8.11 Tax Matters.

          (a) It is intended that each REMIC created pursuant to the
Preliminary Statement shall constitute, and that the affairs of the Trust Fund
shall be conducted so that each REMIC created pursuant to the Preliminary
Statement qualifies as, a "real estate mortgage

                                    -111-
<PAGE>

investment conduit" as defined in and in accordance with the REMIC Provisions.
In furtherance of such intention, the Trustee covenants and agrees that it
shall act as agent (and the Trustee is hereby appointed to act as agent) on
behalf of the Trust Fund and that in such capacity it shall: (a) prepare and
file, or cause to be prepared and filed, in a timely manner, a U.S. Real
Estate Mortgage Investment Conduit Income Tax Returns (Form 1066 or any
successor form adopted by the Internal Revenue Service) and prepare and file
or cause to be prepared and filed with the Internal Revenue Service and
applicable state or local tax authorities income tax or information returns
for each taxable year with respect to each REMIC created hereunder containing
such information and at the times and in the manner as may be required by the
Code or state or local tax laws, regulations, or rules, and furnish or cause
to be furnished to Certificateholders the schedules, statements or information
at such times and in such manner as may be required thereby; (b) within thirty
days of the Closing Date, furnish or cause to be furnished to the Internal
Revenue Service, on Forms 8811 or as otherwise may be required by the Code,
the name, title, address, and telephone number of the person that the Holders
of the Certificates may contact for tax information relating thereto, together
with such additional information as may be required by such Form, and update
such information at the time or times in the manner required by the Code for
the Trust Fund; (c) make or cause to be made elections, on behalf of each
REMIC created hereunder to be treated as a REMIC on the federal tax return of
each such REMIC for its first taxable year (and, if necessary, under
applicable state law); (d) prepare and forward, or cause to be prepared and
forwarded, to the Certificateholders and to the Internal Revenue Service and,
if necessary, state tax authorities, all information returns and reports as
and when required to be provided to them in accordance with the REMIC
Provisions, including without limitation, the calculation of any original
issue discount using the Prepayment Assumption; (e) provide information
necessary for the computation of tax imposed on the transfer of a Class A-R
Certificate to a Person that is not a Permitted Transferee, or an agent
(including a broker, nominee or other middleman) of a Non-Permitted
Transferee, or a pass-through entity in which a Non-Permitted Transferee is
the record holder of an interest (the reasonable cost of computing and
furnishing such information may be charged to the Person liable for such tax);
(f) to the extent that they are under its control conduct the affairs of the
Trust Fund at all times that any Certificates are outstanding so as to
maintain the status of each REMIC created hereunder as a REMIC under the REMIC
Provisions; (g) not knowingly or intentionally take any action or omit to take
any action that would cause the termination of the REMIC status of any REMIC
created hereunder; (h) pay, from the sources specified in Section 8.11(c), the
amount of any federal, state and local taxes, including prohibited transaction
taxes as described below, imposed on any REMIC created hereunder prior to the
termination of the Trust Fund when and as the same shall be due and payable
(but such obligation shall not prevent the Trustee or any other appropriate
Person from contesting any such tax in appropriate proceedings and shall not
prevent the Trustee from withholding payment of such tax, if permitted by law,
pending the outcome of such proceedings); (i) sign or cause to be signed
federal, state or local income tax or information returns; (j) maintain
records relating to each REMIC created hereunder, including but not limited to
the income, expenses, assets and liabilities of each such REMIC, and the fair
market value and adjusted basis of the Trust Fund property determined at such
intervals as may be required by the Code, as may be necessary to prepare the
foregoing returns, schedules, statements or information; and (k) as and when
necessary and appropriate, represent the Trust Fund in any administrative or
judicial proceedings relating to an examination or audit by any governmental
taxing authority, request an administrative adjustment as to any taxable year
of any

                                    -112-
<PAGE>

REMIC created hereunder, enter into settlement agreements with any
governmental taxing agency, extend any statute of limitations relating to any
tax item of the Trust Fund, and otherwise act on behalf of any REMIC created
hereunder in relation to any tax matter involving any such REMIC.

          (b) In order to enable the Trustee to perform its duties as set
forth herein, the Depositor shall provide, or cause to be provided, to the
Trustee within 10 days after the Closing Date all information or data that the
Trustee requests in writing and determines to be relevant for tax purposes to
the valuations and offering prices of the Certificates, including, without
limitation, the price, yield, prepayment assumption and projected cash flows
of the Certificates and the Mortgage Loans (and, to the extent not part of the
aforementioned, the information referred to in paragraphs (i), (ii), (iii) and
(iv) of Section 4.05(d)). Thereafter, the Depositor shall provide to the
Trustee promptly upon written request therefor, any such additional
information or data that the Trustee may, from time to time, request in order
to enable the Trustee to perform its duties as set forth herein. The Depositor
hereby indemnifies the Trustee for any losses, liabilities, damages, claims or
expenses of the Trustee arising from any errors or miscalculations of the
Trustee that result from any failure of the Depositor to provide, or to cause
to be provided, accurate information or data to the Trustee on a timely basis.

          (c) In the event that any tax is imposed on "prohibited
transactions" of the Trust Fund as defined in Section 860F(a)(2) of the Code,
on the "net income from foreclosure property" of the Trust Fund as defined in
Section 860G(c) of the Code, on any contribution to the Trust Fund after the
startup day pursuant to Section 860G(d) of the Code, or any other tax is
imposed, including, without limitation, any federal, state or local tax or
minimum tax imposed upon the Trust Fund pursuant to Sections 23153 and 24872
of the California Revenue and Taxation Code if not paid as otherwise provided
for herein, such tax shall be paid by (i) the Trustee, if any such other tax
arises out of or results from a breach by the Trustee of any of its
obligations under this Agreement, (ii) (x) the Master Servicer, in the case of
any such minimum tax, and (y) any party hereto (other than the Trustee) to the
extent any such other tax arises out of or results from a breach by such other
party of any of its obligations under this Agreement or (iii) in all other
cases, or in the event that any liable party here fails to honor its
obligations under the preceding clauses (i) or (ii), any such tax will be paid
first with amounts otherwise to be distributed to the Class A-R
Certificateholders, and second with amounts otherwise to be distributed to all
other Certificateholders in the following order of priority: first to the
Class M-3 Certificates, second, to the Class M-2 Certificates, third, to the
Class M-1 Certificates, and fourth, to the Class A-R Certificates and the
Class A Certificates (pro rata). Notwithstanding anything to the contrary
contained herein, to the extent that such tax is payable by the Class A-R
Certificates, the Trustee is hereby authorized to retain on any Distribution
Date, from the Holders of the Class A-R Certificates (and, if necessary,
second, from the Holders of the all other Certificates in the priority
specified in the preceding sentence), funds otherwise distributable to such
Holders in an amount sufficient to pay such tax. The Trustee agrees to
promptly notify in writing the party liable for any such tax of the amount
thereof and the due date for the payment thereof.

          (d) The Trustee shall treat the Carryover Reserve Fund as an outside
reserve fund within the meaning of Treasury Regulation 1.860G-2(h) that is
owned by the Class A-IO Certificateholders, and that is not an asset of any
REMIC created under this Agreement. For

                                    -113-
<PAGE>

applicable tax purposes only, the Trustee shall (i) treat the rights of the
Class A-1, Class A-2, Class A-3, Class M-1, Class M-2 and Class M-3
Certificateholders to receive payments from the Carryover Reserve Fund as
rights under an interest rate cap contract between the Class A-1, Class A-2,
Class A-3, Class M-1, Class M-2 and Class M-3 Certificateholders and the Class
A-IO Certificateholders and (ii) treat the Class A-IO Certificateholders as
holding the entire interest in the right to receive payments on the Corridor
Contract. Thus, each Class A-1, Class A-2, Class A-3, Class M-1, Class M-2 and
Class M-3 Certificate shall be treated as representing ownership of not only
Master REMIC Regular Interests, but also ownership of an interest in an
interest rate cap contract. For purposes of determining the issue price of the
Class A-1, Class A-2, Class A-3, Class M-1, Class M-2 and Class M-3
Certificate, the Trustee shall assume that the deemed interest rate cap
contract written by the Class A-IO Certificateholders has a value of $10,000.
As required under Treasury Regulation 1.860G-2(i), the Trustee shall account
for the rights of the Class A-1, Class A-2, Class A-3, Class M-1, Class M-2
and Class M-3 Certificateholders to receive payments from the Carryover
Reserve Fund, and the rights of the Class A-IO Certificateholders to receive
payments from the Corridor Contract, as property that the Trustee holds
separate and apart from the Master REMIC Regular Interests.

          Section 8.12 Co-Trustee.

          (a) The Co-Trustee has been appointed at a Minnesota office solely
to (i) receive and hold the Loan Insurance Policy on behalf of the
Certificateholders and (ii) make payments and receive proceeds paid in respect
of the Mortgage Loans pursuant to the Loan Insurance Policy and take the other
actions expressly provided for in this Agreement. The Co-Trustee, not in its
individual capacity but solely in its capacity as Co-Trustee on behalf of the
Certificateholders, is hereby directed to hold the Loan Insurance Policy for
the benefit of the Certificateholders. The Co-Trustee acknowledges receipt of
the Loan Insurance Policy and agrees to perform its duties at that office in
the manner described below.

          (b) The Co-Trustee shall not undertake nor have any of the duties of
the Trustee and shall have no obligations under this Agreement other than as
expressly stated in this Section 8.12.

          On each Distribution Date upon receipt of funds from the Master
Servicer in accordance with Section 3.09, the Co-Trustee shall pay the amount
received from the Master Servicer to the Loan Insurance Policy Provider on the
Distribution Date by wire transfer of immediately available funds in
accordance with instructions furnished by the Loan Insurance Policy Provider
pursuant to the Loan Insurance Policy. The Master Servicer shall make any
claims pursuant to and in accordance with the Loan Insurance Policy and,
except for the duties of the Co-Trustee in this Section 8.12, shall perform
all of the obligations of the insured under the Loan Insurance Policy on
behalf of the Co-Trustee and for the benefit of the Certificateholders. If the
Co-Trustee receives any payments under the Loan Insurance Policy from the Loan
Insurance Policy Provider, the Co-Trustee shall notify the Trustee of the
receipt of such amounts and shall pay them to the Trustee by wire transfer of
immediately available funds on the date of receipt if received before 2:00
P.M. (New York City time), and otherwise on the next Business Day. The wiring
instructions for the Trustee are:

payment shall be deemed to have been received by the Co-Trustee on the date
that payment cleared and was available to the Co-Trustee in immediately
available funds.

          No provision of this Agreement shall be construed to relieve the
Co-Trustee from liability for its own grossly negligent action, its own gross
negligent failure to act or its own misconduct, its grossly negligent failure
to perform its obligations in compliance with this Agreement, or any liability
that would be imposed by reason of its willful misfeasance or bad faith;
provided that:

               (i) the duties and obligations of the Co-Trustee shall be
     determined solely by the express provisions of this Agreement with the
     exception of Section 8.10, the Co-Trustee shall not be liable,
     individually or as Co-Trustee, except for the performance of such duties
     and obligations as are specifically set forth in this Agreement, no
     implied covenants or obligations shall be read into this Agreement
     against the Co-Trustee, and it may conclusively rely, as to the truth of
     the statements and the correctness of the opinions expressed therein,
     upon any certificates or opinions furnished to it and conforming to the
     requirements of this Agreement that it reasonably believed in good faith
     to be genuine and to have been duly executed by the proper authorities
     respecting any matters arising hereunder; and

               (ii) the Co-Trustee shall not be liable, individually or as
     Co-Trustee, for an error of judgment made in good faith by a Responsible
     Officer or Responsible Officers of the Co-Trustee, unless the Co-Trustee
     was grossly negligent or acted in bad faith or with willful misfeasance.

          (c) Except as otherwise provided in paragraph (b) above:

               (i) the Co-Trustee may request and rely upon and shall be
     protected in acting or refraining from acting upon any resolution,
     Officer's Certificate, certificate of auditors or any other certificate,
     statement, instrument, opinion, report, notice, request, consent, order,
     appraisal, bond or other paper or document believed by it to be genuine
     and to have been signed or presented by the proper party or parties;

               (ii) the Co-Trustee may consult with counsel and any Opinion of
     Counsel shall be full and complete authorization and protection in
     respect of any action taken or suffered or omitted by it hereunder in
     good faith and in accordance with such Opinion of Counsel;

               (iii) the Co-Trustee shall not be liable, individually or as
     Co-Trustee, for any action taken, suffered or omitted by it in good faith
     and believed by it to be

                                    -115-
<PAGE>

     authorized or within the discretion or rights or powers conferred upon it
     by this Agreement;

               (iv) the Co-Trustee shall not be bound to make any
     investigation into the facts or matters stated in any resolution,
     certificate, statement, instrument, opinion, report, notice, request,
     consent, order, approval, bond or other paper or document;

               (v) the Co-Trustee may execute any of the trusts or powers
     hereunder or perform any duties hereunder either directly or by or
     through agents, accountants or attorneys; and

               (vi) the Co-Trustee shall not be required to expend its own
     funds or otherwise incur any financial liability in the performance of
     any of its duties hereunder if it shall have reasonable grounds for
     believing that repayment of such funds or adequate indemnity against such
     liability is not assured to it.

          (d) The recitals contained herein shall be taken as the statements
of the Depositor or the Master Servicer, as the case may be, and the
Co-Trustee assumes no responsibility for their correctness. The Co-Trustee
makes no representations as to the validity or sufficiency of this Agreement,
the Loan Insurance Policy or of any Mortgage Loan or related document.

          (e) The Co-Trustee in its individual or any other capacity may
become the owner or pledgee of Certificates with the same rights as it would
have if it were not the Co-Trustee.

          (f) The Master Servicer covenants and agrees (i) to pay to the
Co-Trustee from time to time, and the Co-Trustee shall be entitled to, such
compensation as shall be agreed in writing by the Master Servicer and the
Co-Trustee (which shall not be limited by any provision of law in regard to
the compensation of a trustee of an express trust) for all services rendered
by it in the execution of the trusts hereby created and in the exercise and
performance of any of the powers and duties hereunder of the Co-Trustee and
(ii) to pay or reimburse the Co-Trustee, upon its request, for all reasonable
expenses, disbursements and advances incurred or made by the Co-Trustee on
behalf of the Trust Fund in accordance with any of the provisions of this
Agreement (including, without limitation: (A) the reasonable compensation and
the expenses and disbursements of its counsel, but only for representation of
the Co-Trustee acting in its capacity as Co-Trustee hereunder and (B) to the
extent that the Co-Trustee must engage persons not regularly in its employ to
perform acts or services on behalf of the Trust Fund, which acts or services
are not in the ordinary course of the duties of a trustee, paying agent or
certificate registrar, in the absence of a breach or default by any party
hereto, the reasonable compensation, expenses and disbursements of such
persons, except any such expense, disbursement or advance as may arise from
its negligence, bad faith or willful misconduct). The Co-Trustee and any
director, officer, employee or agent of the Co-Trustee shall be indemnified by
the Master Servicer and held harmless against any loss, liability or expense
(i) incurred in connection with any legal action relating to this Agreement,
the Loan Insurance Policy or the Certificates, or in connection with the
performance of any of the Co-Trustee's duties hereunder, other than any loss,
liability or expense incurred by reason of willful misfeasance, bad faith or
negligence in the

                                    -116-

<PAGE>

performance of any of the Co-Trustee's duties hereunder or by reason of
reckless disregard of the Co-Trustee's obligations and duties hereunder and
(ii) resulting from any error in any tax or information return prepared by the
Master Servicer. Such indemnity shall survive the termination of this
Agreement or the resignation or removal of the Co-Trustee hereunder.

          (g) The Co-Trustee hereunder shall, at all times, be a corporation
or association organized and doing business under the laws of a state or the
United States of America, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus of at least $50,000,000,
subject to supervision or examination by federal or state authority and with a
credit rating that would not cause any of the Rating Agencies to reduce their
respective ratings of any Class of Certificates below the ratings issued on
the Closing Date (or having provided such security from time to time as is
sufficient to avoid such reduction), and otherwise acceptable to the Loan
Insurance Policy Provider. If such corporation or association publishes
reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid supervising or examining authority, then for the purposes of
this Section 8.12 the combined capital and surplus of such corporation or
association shall be deemed to be its combined capital and surplus as set
forth in its most recent report of condition so published. In case at any time
the Co-Trustee shall cease to be eligible in accordance with the provisions of
this Section 8.12, the Co-Trustee shall resign immediately in the manner and
with the effect specified in paragraph (h) below. The corporation or national
banking association serving as Co-Trustee may have normal banking and trust
relationships with the Depositor, the Seller and the Master Servicer and their
respective affiliates; provided that such corporation cannot be an affiliate
of the Master Servicer other than the Trustee in its role as successor to the
Master Servicer. If at any time (i) the Co-Trustee ceases to be eligible in
accordance with this Section 8.12(g) and fails to resign after written request
by the Loan Insurance Policy Provider or the Trustee, or (ii) the Co-Trustee
becomes incapable of acting, or is adjudged a bankrupt or insolvent, or a
receiver of the Co-Trustee or of its property is appointed, or any public
officer takes charge of the Co-Trustee or of its property or affairs for the
purpose of rehabilitation, conservation, or liquidation, then the Loan
Insurance Policy Provider or Trustee may remove the Co-Trustee and appoint a
successor co-trustee by written instrument, with copies delivered to the
Co-Trustee, the Trustee, Loan Insurance Policy Provider and the successor
co-trustee. Any successor co-trustee shall be paid pursuant to an agreement
with the Master Servicer and the assets of the Trust Fund shall not be used to
satisfy any obligation to pay the compensation of the successor co-trustee.
Any resignation or removal of the Co-Trustee and appointment of a successor
co-trustee pursuant to this Section shall become effective only upon
acceptance of appointment by the successor co-trustee as provided in this
Section.

          (h) The Co-Trustee may at any time resign and be discharged from the
trusts hereby created by giving 30 days prior written notice of resignation to
the Trustee, the Loan Insurance Policy Provider, the Depositor and the Master
Servicer. Upon such resignation the Trustee (x) may appoint a successor
Co-Trustee meeting the requirements in paragraph (g) above and acceptable to
the Master Servicer (in its sole discretion), so long as such Co-Trustee
executes and delivers to the other parties hereto and to the Loan Insurance
Policy Provider an instrument agreeing to be bound by the provisions of this
Agreement or (y) may if permitted by the Master Servicer (in its sole
discretion) assume the rights and duties of the resigning Co-Trustee so long
as the Trustee executes and delivers an instrument to that effect. The
Co-Trustee shall deliver

                                    -117-

<PAGE>

the Loan Insurance Policy and any amounts held in its possession for the
benefit of the Certificateholders to the successor co-trustee upon the
appointment of the successor co-trustee.

          (i) The Co-Trustee shall surrender the Loan Insurance Policy to the
Loan Insurance Policy Provider for cancellation upon the termination of the
Trust Fund.

          Section 8.13 Access to Records of the Trustee and the Co-Trustee.

          The Trustee, the Co-Trustee and any other co-trustee shall, upon
reasonable notice, afford the Seller, the Depositor, the Master Servicer and
each Certificate Owner, access during normal business hours, access to all
records maintained by the Trustee, Co-Trustee or co-trustee in respect of its
duties under this Agreement and access to officers of the Trustee, Co-Trustee
or co-trustee responsible for performing its duties. Upon request, the
Trustee, the Co-Trustee or the co-trustee shall furnish the Depositor, the
Master Servicer and any requesting Certificate Owner with its most recent
financial statements. The Trustee, the Co-Trustee and any other co-trustee
shall cooperate fully with the Seller, the Master Servicer, the Depositor and
each Certificate Owner in its review in the copying of any books, documents,
or records requested with respect to the Trustee's, Co-Trustee's or
co-trustee's respective duties under this Agreement. None of the Seller, the
Depositor, the Master Servicer or any Certificate Owner shall have any
responsibility or liability for any action for failure to act by the Trustee,
the Co-Trustee or any co-trustee, and none of such persons is obligated to
supervise the performance of the Trustee or the Co-Trustee under this
Agreement or otherwise.

          Section 8.14 Suits for Enforcement.

          If an Event of Default or other material default by the Master
Servicer or the Depositor under this Agreement occurs and is continuing, at
the direction of the Certificateholders holding not less than 51% of the
Voting Rights, the Trustee shall proceed to protect and enforce its rights and
the rights of the Certificateholders under this Agreement by a suit, action,
or proceeding in equity or at law or otherwise, whether for the specific
performance of any covenant or agreement contained in this Agreement or in aid
of the execution of any power granted in this Agreement or for the enforcement
of any other legal, equitable, or other remedy, as the Trustee, on the advice
of counsel, and subject to the foregoing, shall deem most effectual to protect
and enforce any of the rights of the Trustee and the Certificateholders.

                                  TERMINATION

          Section 9.01 Termination upon Liquidation or Repurchase of all
                       Mortgage Loans.

          Subject to Section 9.03, the Trust Fund shall terminate and the
obligations and responsibilities of the Depositor, the Master Servicer, the
Seller and the Trustee created hereby shall terminate upon the earlier of (a)
the purchase by the Master Servicer of all of the Mortgage Loans (and REO
Properties) remaining in the Trust Fund at the price equal to the sum of (i)
100% of the Stated Principal Balance of each Mortgage Loan in the Trust Fund
(other than in respect of an REO Property), (ii) accrued interest thereon at
the applicable Net Mortgage Rate, (iii) the appraised value of any REO
Property in the Trust Fund (up to the Stated Principal Balance of the related
Mortgage Loan), such appraisal to be conducted by an appraiser mutually agreed
upon by the Master Servicer and the Trustee and (iv) any unreimbursed
Servicing Advances, and the principal portion of any unreimbursed Advances,
made on the Mortgage Loans prior to the exercise of such repurchase and (b)
the later of (i) the maturity or other liquidation (or any Advance with
respect thereto) of the last Mortgage Loan remaining in the Trust Fund and the
disposition of all REO Property and (ii) the distribution to
Certificateholders of all amounts required to be distributed to them pursuant
to this Agreement, as applicable. In no event shall the trusts created hereby
continue beyond the earlier of (i) the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late
Ambassador of the United States to the Court of St. James's, living on the
date hereof and (ii) the Latest Possible Maturity Date.

          The Master Servicer shall have the right to repurchase all Mortgage
Loans and REO Properties in the Trust Fund pursuant to clause (a) in the
preceding paragraph only on or after the date on which the Stated Principal
Balance of the Mortgage Loans, at the time of any such repurchase, is less
than or equal to ten percent (10%) of the Stated Principal Balance of the
Mortgage Loans as of the Cut-off Date.

          Section 9.02 Final Distribution on the Certificates.

          If on any Determination Date, (i) the Master Servicer determines
that there are no Outstanding Mortgage Loans and no other funds or assets in
the Trust Fund other than the funds in the Certificate Account, the Master
Servicer shall direct the Trustee to send a final distribution notice promptly
to each Certificateholder or (ii) the Trustee determines that a Class of
Certificates shall be retired after a final distribution on such Class, the
Trustee shall notify the related Certificateholders within five (5) Business
Days after such Determination Date that the final distribution in retirement
of such Class of Certificates is scheduled to be made on the immediately
following Distribution Date. Any final distribution made pursuant to the
immediately preceding sentence will be made only upon presentation and
surrender of the related Certificates at the Corporate Trust Office of the
Trustee. If the Master Servicer elects to terminate the Trust Fund pursuant to
clause (a) of Section 9.01, at least 20 days prior to the date notice is to be
mailed to the Certificateholders, such electing party shall notify the
Depositor and

                                    -119-
<PAGE>

the Trustee of the date such electing party intends to terminate the Trust
Fund and of the applicable repurchase price of the related Mortgage Loans and
REO Properties.

          Notice of any termination of the Trust Fund, specifying the
Distribution Date on which related Certificateholders may surrender their
Certificates for payment of the final distribution and cancellation, shall be
given promptly by the Trustee by letter to related Certificateholders mailed
not earlier than the 10th day and no later than the 15th day of the month
immediately preceding the month of such final distribution. Any such notice
shall specify (a) the Distribution Date upon which final distribution on
related Certificates will be made upon presentation and surrender of such
Certificates at the office therein designated, (b) the amount of such final
distribution, (c) the location of the office or agency at which such
presentation and surrender must be made, and (d) that the Record Date
otherwise applicable to such Distribution Date is not applicable,
distributions being made only upon presentation and surrender of such
Certificates at the office therein specified. The Master Servicer will give
such notice to each Rating Agency at the time such notice is given to the
affected Certificateholders.

          In the event such notice is given, the Master Servicer shall cause
all funds in the Certificate Account to be remitted to the Trustee for deposit
in the Distribution Account on the Business Day prior to the applicable
Distribution Date in an amount equal to the final distribution in respect of
the related Certificates. Upon such final deposit and the receipt by the
Trustee of a Request for Release therefor, the Trustee shall promptly release
to the Master Servicer the Mortgage Files for the related Mortgage Loans.

          Upon presentation and surrender of the related Certificates, the
Trustee shall cause to be distributed to Certificateholders of each affected
Class the amounts allocable to such Certificates held in the Distribution
Account (and, if applicable, the Carryover Reserve Fund) in the order and
priority set forth in Section 4.04 hereof on the final Distribution Date and
in proportion to their respective Percentage Interests. Notwithstanding the
reduction of the Certificate Principal Balance of any Class of Certificates to
zero, such Class will be outstanding hereunder (solely for the purpose of
receiving distributions (if any) to which it may be entitled pursuant to the
terms of this Agreement and not for any other purpose) until the termination
of the respective obligations and responsibilities of the Depositor, each
Seller, the Master Servicer and the Trustee hereunder in accordance with this
Article IX.

          In the event that any affected Certificateholders shall not
surrender related Certificates for cancellation within six months after the
date specified in the above mentioned written notice, the Trustee shall give a
second written notice to the remaining Certificateholders to surrender their
related Certificates for cancellation and receive the final distribution with
respect thereto. If within six months after the second notice all the
applicable Certificates shall not have been surrendered for cancellation, the
Trustee may take appropriate steps, or may appoint an agent to take
appropriate steps, to contact the remaining Certificateholders concerning
surrender of their Certificates, and the cost thereof shall be paid out of the
funds and other assets that remain a part of the Trust Fund. If within one
year after the second notice all related Certificates shall not have been
surrendered for cancellation, the Class A-R Certificateholders shall be
entitled to all unclaimed funds and other assets that remain subject hereto.

          Section 9.03 Additional Termination Requirements.

          (a) In the event the Master Servicer exercises its purchase option
on the Mortgage Loans, the Trust Fund shall be terminated in accordance with
the following additional requirements, unless the Trustee has been supplied
with an Opinion of Counsel, at the expense of the Master Servicer, to the
effect that the failure of the Trust Fund to comply with the requirements of
this Section 9.03 will not (i) result in the imposition of taxes on
"prohibited transactions" of a REMIC, or (ii) cause any REMIC created
hereunder to fail to qualify as a REMIC at any time that any Certificates are
outstanding:

                    (1) The Master Servicer shall establish a 90-day
liquidation period and notify the Trustee thereof, which shall in turn specify
the first day of such period in a statement attached to the Trust Fund's final
Tax Return pursuant to Treasury Regulation Section 1.860F-1. The Master
Servicer shall prepare a plan of complete liquidation and shall otherwise
satisfy all the requirements of a qualified liquidation under Section 860F of
the Code and any regulations thereunder, as evidenced by an Opinion of Counsel
delivered to the Trustee and the Depositor and obtained at the expense of the
Master Servicer;

                    (2) During such 90-day liquidation period, and at or prior
to the time of making the final payment on the Certificates, the Master
Servicer as agent of the Trustee shall sell all of the assets of the Trust
Fund for cash; and

                    (3) At the time of the making of the final payment on the
Certificates, the Trustee shall distribute or credit, or cause to be
distributed or credited, to the Class A-R Certificateholders all cash on hand
(other than cash retained to meet claims) related to such Class of
Certificates, and the Trust Fund shall terminate at that time.

          (b) By their acceptance of the Certificates, the Holders thereof
hereby authorize the Master Servicer to specify the 90-day liquidation period
for the Trust Fund, which authorization shall be binding upon all successor
Certificateholders. The Trustee shall attach a statement to the final federal
income tax return for each of any REMIC created hereunder stating that
pursuant to Treasury Regulation Section 1.860F-1, the first day of the 90-day
liquidation period for each the REMIC was the date on which the Trustee sold
the assets of the Trust Fund to the Master Servicer.

          (c) The Trustee as agent for each REMIC created hereunder hereby
agrees to adopt and sign such a plan of complete liquidation upon the written
request of the Master Servicer, and the receipt of the Opinion of Counsel
referred to in Section 9.03(a)(1), and together with the Holders of the Class
A-R Certificates agree to take such other action in connection therewith as
may be reasonably requested by the Master Servicer.

                           MISCELLANEOUS PROVISIONS

          Section 10.01 Amendment.

          This Agreement may be amended from time to time by the Depositor,
the Master Servicer, the Seller, the Co-Trustee and the Trustee, without the
consent of any of the Certificateholders, (i) to cure any ambiguity, (ii) to
correct or supplement any provisions herein, (iii) to conform this Agreement
to the Prospectus Supplement or the Prospectus, (iv) to modify, alter, amend,
add to or rescind any of the terms or provisions contained in this Agreement
to comply with any rules or regulations promulgated by the Securities and
Exchange Commission from time to time or (v) to make such other provisions
with respect to matters or questions arising under this Agreement, as shall
not be inconsistent with any other provisions herein if such action shall not,
as evidenced by an Opinion of Counsel, adversely affect in any material
respect the interests of any Certificateholder; provided that any such
amendment shall be deemed not to adversely affect in any material respect the
interests of the Certificateholders and no such Opinion of Counsel shall be
required if the Person requesting such amendment obtains a letter from each
Rating Agency stating that such amendment would not result in the downgrading
or withdrawal of the respective ratings then assigned to the Certificates, it
being understood and agreed that any such letter in and of itself will not
represent a determination as to the materiality of any such amendment and will
represent a determination only as to the credit issues affecting any such
rating. Notwithstanding the foregoing, no amendment that significantly changes
the permitted activities of the trust created by this Agreement may be made
without the consent of Certificateholders representing not less than 51% of
the Voting Rights of each Class of Certificates affected by such amendment.
Each party to this Agreement hereby agrees that it will cooperate with each
other party in amending this Agreement pursuant to clause (iv) above.

          The Trustee, the Co-Trustee, the Depositor, the Master Servicer and
the Seller may also at any time and from time to time amend this Agreement,
without the consent of the Certificateholders, to modify, eliminate or add to
any of its provisions to such extent as shall be necessary or appropriate to
maintain the qualification of the Trust Fund as a REMIC under the Code or to
avoid or minimize the risk of the imposition of any tax on the Trust Fund
pursuant to the Code that would be a claim against the Trust Fund at any time
prior to the final redemption of the Certificates, provided that the Trustee
has been provided an Opinion of Counsel, which shall be an expense of the
party requesting it but in any case shall not be an expense of the Trustee, to
the effect that such action is necessary or appropriate to maintain such
qualification or to avoid or minimize the risk of the imposition of such a
tax.

          This Agreement may also be amended from time to time by the
Depositor, the Master Servicer, the Seller and the Trustee and the Holders of
not less than 51% of the Voting Rights of each Class of Certificates adversely
affected thereby for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Agreement or of
modifying in any manner the rights of the Holders of Certificates; provided
that no such amendment shall (i) reduce in any manner the amount of, or delay
the timing of, payments required to be distributed on any Certificate without
the consent of the Holder of such Certificate, (ii) adversely affect in any
material respect the interests of the Holders of any Class

                                    -122-
<PAGE>

of Certificates in a manner other than as described in clause (i), without the
consent of the Holders of Certificates of such Class evidencing 66% or more of
the Voting Rights of such Class or (iii) reduce the aforesaid percentages of
Certificates whose Holders are required to consent to any such amendment,
without the consent of the Holders of all then outstanding Certificates of
such class.

          Notwithstanding any contrary provision of this Agreement, the
Trustee shall not consent to any amendment to this Agreement unless it shall
have first received an Opinion of Counsel, which shall be an expense of the
party requesting such amendment but in any case shall not be an expense of the
Trustee, to the effect that such amendment will not cause the imposition of
any tax on the Trust Fund or the Certificateholders or cause any REMIC formed
hereunder to fail to qualify as a REMIC at any time that any Certificates are
outstanding.

          Promptly after the execution of any amendment to this Agreement
requiring the consent of Certificateholders, the Trustee shall furnish written
notification of the substance of such amendment to each Certificateholder and
each Rating Agency.

          It shall not be necessary for the consent of Certificateholders
under this Section to approve the particular form of any proposed amendment,
but it shall be sufficient if such consent shall approve the substance
thereof. The manner of obtaining such consents and of evidencing the
authorization of the execution thereof by Certificateholders shall be subject
to such reasonable regulations as the Trustee may prescribe.

          Nothing in this Agreement shall require the Trustee to enter into an
amendment without receiving an Opinion of Counsel, reasonably satisfactory to
the Trustee that (i) such amendment is permitted and is not prohibited by this

THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS
WITHOUT REGARD TO THE CONFLICTS OF LAWS PRINCIPLES THEREOF.

          Section 10.04 Intention of Parties.

          It is the express intent of the parties hereto that the conveyance
of the Mortgage Notes, Mortgages, assignments of Mortgages, title insurance
policies and any modifications, extensions and/or assumption agreements and
private mortgage insurance policies relating to the Mortgage Loans by the
Depositor to the Trustee be, and be construed as, an absolute sale thereof to
the Trustee. It is, further, not the intention of the parties that such
conveyance be deemed a pledge thereof by the Depositor to the Trustee.
However, in the event that, notwithstanding the intent of the parties, such
assets are held to be the property of the Depositor, or if for any other
reason this Agreement is held or deemed to create a security interest in such
assets, then (i) this Agreement shall be deemed to be a security agreement
(within the meaning of the Uniform Commercial Code of the State of New York)
with respect to all such assets and security interests and (ii) the conveyance
provided for in this Agreement shall be deemed to be an assignment and a grant
pursuant to the terms of this Agreement by the Depositor to the Trustee, for
the benefit of the Certificateholders, of a security interest in all of the
assets that constitute the Trust Fund, whether now owned or hereafter
acquired.

          The Depositor for the benefit of the Certificateholders shall, to
the extent consistent with this Agreement, take such actions as may be
necessary to ensure that, if this Agreement were deemed to create a security
interest in the assets of the Trust Fund, such security interest would be
deemed to be a perfected security interest of first priority under applicable
law and will be maintained as such throughout the term of this Agreement. The
Depositor shall arrange for filing any Uniform Commercial Code continuation
statements in connection with any security interest granted or assigned to the
Trustee for the benefit of the Certificateholders.

          Section 10.05 Notices.

          (a) The Trustee shall use its best efforts to promptly provide
notice to each Rating Agency with respect to each of the following of which it
has actual knowledge:

               (i) Any material change or amendment to this Agreement;

               (ii) The occurrence of any Event of Default that has not been
     cured;

               (iii) The resignation or termination of the Master Servicer or
     the Trustee and the appointment of any successor;

               (iv) The repurchase or substitution of Mortgage Loans pursuant
     to Sections 2.02, 2.03, 2.04 and 3.12; and

          The death or incapacity of any Certificateholder shall not operate
to terminate this Agreement or the Trust Fund, nor entitle such
Certificateholder's legal representative or heirs to claim an accounting or to
take any action or commence any proceeding in any court for a petition or
winding up of the Trust Fund, or otherwise affect the rights, obligations and
liabilities of the parties hereto or any of them.

          No Certificateholder shall have any right to vote (except as
provided herein) or in any manner otherwise control the operation and
management of the Trust Fund, or the obligations of the parties hereto, nor
shall anything herein set forth or contained in the terms of the Certificates
be construed so as to constitute the Certificateholders from time to time as
partners or members of an association; nor shall any Certificateholder be
under any liability to any third party by reason of any action taken by the
parties to this Agreement pursuant to any provision hereof.

          No Certificateholder shall have any right by virtue or by availing
itself of any provisions of this Agreement to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this
Agreement, unless such Holder previously shall have given to the Trustee a
written notice of an Event of Default and of the continuance thereof, as
hereinbefore provided, the Holders of Certificates evidencing not less than
25% of the Voting Rights evidenced by the Certificates shall also have made
written request to the Trustee to institute such action, suit or proceeding in
its own name as Trustee hereunder and shall have offered to the Trustee such
reasonable indemnity as it may require against the costs, expenses, and
liabilities to be incurred therein or thereby, and the Trustee, for 60 days
after its receipt of such notice, request and offer of indemnity shall have
neglected or refused to institute any such action, suit or proceeding; it
being understood and intended, and being expressly covenanted by each
Certificateholder with every other Certificateholder and the Trustee, that no
one or more Holders of Certificates shall have any right in any manner
whatever by virtue or by availing itself or themselves of any provisions of
this Agreement to affect, disturb or prejudice the rights of the Holders of
any other of the Certificates, or to obtain or seek to obtain priority over or
preference to any other such Holder or to enforce any right under this
Agreement, except in the manner herein provided and for the common benefit of
all Certificateholders. For the protection and enforcement of the provisions
of this Section 10.08, each and every Certificateholder and the Trustee shall
be entitled to such relief as can be given either at law or in equity.

the Mortgage Loans, to make copies and extracts therefrom, to cause such books
to be audited by independent certified public accountants selected by the
Depositor, the Seller or the Trustee and to discuss its affairs, finances and
accounts relating to the Mortgage Loans with its officers, employees and
independent public accountants (and by this provision the Master Servicer
hereby authorizes such accountants to discuss with such representative such
affairs, finances and accounts), all at such reasonable times and as often as

not be personally liable for obligations of the Trust Fund, that the interests

     Ownership Interest in the Certificate for its own account.

3.   The Transferee has been advised of, and understands that (i) a tax will
     be imposed on Transfers of the Certificate to Persons that are not
     Permitted Transferees; (ii) such tax will be imposed on the transferor,
     or, if such Transfer is through an agent (which includes a broker,
     nominee or middleman) for a Person that is not a Permitted Transferee, on
     the agent; and (iii) the Person otherwise liable for the tax shall be
     relieved of liability for the tax if the subsequent Transferee furnished
     to such Person an affidavit that such subsequent Transferee is a
     Permitted Transferee and, at the time of Transfer, such Person does not
     have actual knowledge that the affidavit is false.

4.   The Transferee has been advised of, and understands that a tax will be
     imposed on a "pass-through entity" holding the Certificate if at any time
     during the taxable year of the pass-through entity a Person that is not a
     Permitted Transferee is the record holder of an interest in such entity.
     The Transferee understands that such tax will not be imposed for any
     period with respect to which the record holder furnishes to the
     pass-through entity an affidavit that such record holder is a Permitted
     Transferee and the pass-through entity does not have actual knowledge
     that such affidavit is false. (For this purpose, a "pass-through entity"
     includes a regulated investment company, a real estate investment trust
     or common trust fund, a partnership, trust or estate, and certain
     cooperatives and, except as may be provided in Treasury Regulations,
     persons holding interests in pass-through entities as a nominee for
     another Person.)

5.   The Transferee has reviewed the provisions of Section 5.02(c) of the
     Agreement (attached hereto as Exhibit 2 and incorporated herein by
     reference) and understands the legal consequences of the acquisition of
     an Ownership Interest in the Certificate including, without limitation,
     the restrictions on subsequent Transfers and the provisions regarding
     voiding the Transfer and mandatory sales. The Transferee expressly agrees
     to be bound by and to abide by the provisions of Section 5.02(c) of the
     Agreement and the restrictions noted on the face of the Certificate. The
     Transferee understands and agrees that any breach of any of the
     representations included herein shall render the Transfer to the
     Transferee contemplated hereby null and void.

6.   The Transferee agrees to require a Transfer Affidavit from any Person to
     whom the Transferee attempts to Transfer its Ownership Interest in the
     Certificate, and in connection with any Transfer by a Person for whom the
     Transferee is acting as nominee, trustee or agent, and the Transferee
     will not Transfer its Ownership Interest or cause any Ownership Interest
     to be Transferred to any Person that the Transferee knows is not a
     Permitted Transferee. In connection with any such Transfer by the
     Transferee, the Transferee agrees to deliver to the Trustee a certificate
     substantially in the form set forth as Exhibit J to the Agreement (a
     "Transferor Certificate") to the effect that such Transferee has no
     actual knowledge that the Person to which the Transfer is to be made is
     not a Permitted Transferee.

7.   The Transferee does not have the intention to impede the assessment or
     collection of any tax legally required to be paid with respect to the
     Class A-R Certificates.

8.   The Transferee's taxpayer identification number is _____.

9.   The Transferee is a U.S. Person as defined in Code Section 7701(a)(30).

10.  The Transferee is aware that the Class A-R Certificates may be
     "noneconomic residual interests" within the meaning of proposed Treasury
     regulations promulgated pursuant to the Code and that the transferor of a
     noneconomic residual interest will remain liable for any taxes due with
     respect to the income on such residual interest, unless no significant
     purpose of the transfer was to impede the assessment or collection of
     tax. In addition, as the holder of a noneconomic residual interest, the
     Transferee may incur tax liabilities in excess of any cash flows
     generated by the interest and the Transferee hereby represents that it
     intends to pay taxes associated with holding the residual interest as
     they become due.

11.  The Transferee has provided financial statements or other financial
     information requested by the Transferor in connection with the transfer
     of the Class A-R Certificates to permit the Transferor to assess the
     financial capability of the Transferee to pay such taxes.

                              Certain Definitions
                              -------------------

     "Ownership Interest": As to any Certificate, any ownership interest in
such Certificate, including any interest in such Certificate as the Holder
thereof and any other interest therein, whether direct or indirect, legal or
beneficial.

     "Permitted Transferee": Any person other than (i) the United States, any
State or political subdivision thereof, or any agency or instrumentality of
any of the foregoing, (ii) a foreign government, International Organization or
any agency or instrumentality of either of the foregoing, (iii) an
organization (except certain farmers' cooperatives described in section 521 of
the Code) that is exempt from tax imposed by Chapter 1 of the Code (including
the tax imposed by section 511 of the Code on unrelated business taxable
income) on any excess inclusions (as defined in section 860E(c)(1) of the
Code) with respect to any Class A-R Certificate, (iv) rural electric and
telephone cooperatives described in section 1381(a)(2)(C) of the Code, (v) an
"electing large partnership" as defined in Section 775 of the Code, (vi) a
Person that is not a citizen or resident of the United States, a corporation,
partnership, or other entity (treated as a corporation or a partnership for
federal income tax purposes) created or organized in or under the laws of the
United States, any state thereof or the District of Columbia, or an estate
whose income from sources without the United States is includible in gross
income for United States federal income tax purposes regardless of its
connection with the conduct of a trade or business within the United States,
or a trust if a court within the United States is able to exercise primary
supervision over the administration of the trust and one or more United States
persons have authority to control all substantial decisions of the trustor
unless such Person has furnished the transferor and the Trustee with a duly
completed Internal Revenue Service Form 4224, and (vii) any other Person so
designated by the Trustee based upon an Opinion of Counsel that the Transfer
of an Ownership Interest in a Class A-R Certificate to such Person may cause
the Trust Fund to fail to qualify as a REMIC at any time that certain
Certificates are Outstanding. The terms "United States," "State" and
"International Organization" shall have the meanings set forth in section 7701
of the Code or successor provisions. A corporation will not be treated as an
instrumentality of the United States or of any State or political subdivision
thereof for these purposes if all of its activities are subject to tax and,
with the exception of the Federal Home Loan Mortgage Corporation, a majority
of its board of directors is not selected by such government unit.

     "Person": Any individual, corporation, limited liability company,
partnership, joint venture, bank, joint stock company, trust (including any
beneficiary thereof), unincorporated organization or government or any agency
or political subdivision thereof.

     "Transfer": Any direct or indirect transfer or sale of any Ownership
Interest in a Certificate, including the acquisition of a Certificate by the
Depositor.

     "Transferee": Any Person who is acquiring by Transfer any Ownership
Interest in a Certificate.

                       Section 5.02(c) of this Agreement
                       ---------------------------------

          (c) Each Person who has or who acquires any Ownership Interest in a
Class A-R Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the following provisions, and
the rights of each Person acquiring any Ownership Interest in a Class A-R
Certificate are expressly subject to the following provisions:

               (i) Each Person holding or acquiring any Ownership Interest in
          a Class A-R Certificate shall be a Permitted Transferee and shall
          promptly notify the Trustee of any change or impending change in its
          status as a Permitted Transferee.

               (ii) No Ownership Interest in a Class A-R Certificate may be
          registered on the Closing Date or thereafter transferred, and the
          Trustee shall not register the Transfer of any Class A-R Certificate
          unless, in addition to the certificates required to be delivered to
          the Trustee under subparagraph (b) above, the Trustee shall have
          been furnished with an affidavit (a "Transfer Affidavit") of the
          initial owner or the proposed transferee in the form attached hereto
          as Exhibit I.

               (iii) Each Person holding or acquiring any Ownership Interest
          in a Class A-R Certificate shall agree (A) to obtain a Transfer
          Affidavit from any other Person to whom such Person attempts to
          Transfer its Ownership Interest in a Class A-R Certificate, (B) to
          obtain a Transfer Affidavit from any Person for whom such Person is
          acting as nominee, trustee or agent in connection with any Transfer
          of a Class A-R Certificate and (C) not to Transfer its Ownership
          Interest in a Class A-R Certificate or to cause the Transfer of an
          Ownership Interest in a Class A-R Certificate to any other Person if
          it has actual knowledge that such Person is not a Permitted
          Transferee.

               (iv) Any attempted or purported Transfer of any Ownership
          Interest in a Class A-R Certificate in violation of the provisions
          of this Section 5.02(c) shall be absolutely null and void and shall
          vest no rights in the purported Transferee. If any purported
          transferee shall become a Holder of a Class A-R Certificate in
          violation of the provisions of this Section 5.02(c), then the last
          preceding Permitted Transferee shall be restored to all rights as
          Holder thereof retroactive to the date of registration of Transfer
          of such Class A-R Certificate. The Trustee shall be under no
          liability to any Person for any registration of Transfer of a Class
          A-R Certificate that is in fact not permitted by Section 5.02(b) and
          this Section 5.02(c) or for making any payments due on such
          Certificate to the Holder thereof or taking any other action with
          respect to such Holder under the provisions of this Agreement so
          long as the Transfer was registered after receipt of the related
          Transfer Affidavit and Transferor Certificate. The Trustee shall be
          entitled but not obligated to recover from any Holder of a Class A-R
          Certificate that was in fact not a Permitted Transferee at the time
          it became a Holder or, at such subsequent time as it became other
          than a Permitted Transferee, all payments made on such Class A-R
          Certificate at and

<PAGE>

          after either such time. Any such payments so recovered by the
          Trustee shall be paid and delivered by the Trustee to the last
          preceding Permitted Transferee of such Certificate.

               (v) The Master Servicer shall use its best efforts to make
          available, upon receipt of written request from the Trustee, all
          information necessary to compute any tax imposed under Section
          860E(e) of the Code as a result of a Transfer of an Ownership
          Interest in a Class A-R Certificate to any Holder who is not a
          Permitted Transferee.

          The restrictions on Transfers of a Class A-R Certificate set forth
in this Section 5.02(c) shall cease to apply (and the applicable portions of
the legend on a Class A-R Certificate may be deleted) with respect to
Transfers occurring after delivery to the Trustee of an Opinion of Counsel,
which Opinion of Counsel shall not be an expense of the Trustee, the Seller or
the Master Servicer to the effect that the elimination of such restrictions
will not cause the Trust Fund to fail to qualify as a REMIC at any time that
the Certificates are outstanding or result in the imposition of any tax on the
Trust Fund, a Certificateholder or another Person. Each Person holding or
acquiring any Ownership Interest in a Class A-R Certificate hereby consents to
any amendment of this Agreement that, based on an Opinion of Counsel furnished
to the Trustee, is reasonably necessary (a) to ensure that the record
ownership of, or any beneficial interest in, a Class A-R Certificate is not
transferred, directly or indirectly, to a Person that is not a Permitted
Transferee and (b) to provide for a means to compel the Transfer of a Class
A-R Certificate that is held by a Person that is not a Permitted Transferee to
a Holder that is a Permitted Transferee.

Ladies and Gentlemen:

          In connection with our acquisition of the above-captioned
Certificates we certify that (a) we understand that the Certificates are not
being registered under the Securities Act of 1933, as amended (the "Act"), or
any state securities laws and are being transferred to us in a transaction
that is exempt from the registration requirements of the Act and any such
laws, (b) we have such knowledge and experience in financial and business
matters that we are capable of evaluating the merits and risks of investments
in the Certificates, (c) we have had the opportunity to ask questions of and
receive answers from the Depositor concerning the purchase of the Certificates
and all matters relating thereto or any additional information deemed
necessary to our decision to purchase the Certificates, (d) either (i) we are
not an employee benefit plan that is subject to the Employee Retirement Income
Security Act of 1974, as amended, or a plan or arrangement that is subject to
Section 4975 of the Internal Revenue Code of 1986, as amended, nor are we
acting on behalf of any such plan or arrangement, nor are we using the assets
of any such plan or arrangement to effect such acquisition or (ii) if the
Certificates have been the subject of an ERISA-Qualifying Underwriting, we are
an insurance company which is purchasing such Certificates with funds
contained in an "insurance company general account" (as such term is defined
in Section V(e) of Prohibited Transaction Class Exemption 95-60 ("PTCE
95-60")) and the purchase and holding of such Certificates are covered under
Sections I and III of PTCE 95-60, (e) we have not, nor has anyone acting on

the disposition of the Certificates a violation of Section 5 of the Securities
Act or require registration pursuant thereto, nor will act, nor has authorized
or will authorize any person to act, in such manner with respect to the
Certificates, (f) we are a "qualified institutional buyer" as that term is
defined in Rule 144A under the Securities Act and have completed either of the
forms of certification to that effect attached hereto as Annex 1 or Annex 2.
We are aware that the sale to us is being made in reliance on Rule 144A. We

     subsidiaries are consolidated with the Buyer in its financial statements
     prepared in accordance with generally accepted accounting principles and
     if the investments of such subsidiaries are managed under the Buyer's
     direction. However, such securities were not included if the Buyer is a
     majority-owned, consolidated subsidiary of another enterprise and the
     Buyer is not itself a reporting company under the Securities Exchange Act
     of 1934, as amended.

     notify each of the parties to which this certification is made of any
     changes in the information and conclusions herein. Until such notice is
     given, the Buyer's purchase of the Certificates will constitute a

     addition, if the Buyer is a bank or savings and loan is provided above,
     the Buyer agrees that it will furnish to such parties updated annual
     financial statements promptly after they become available.

Dear Sir or Madam:

          Reference is made to the Pooling and Servicing Agreement, dated as

Inc., as Depositor, Countrywide Home Loans, Inc., as Seller, Countrywide Home
Loans Servicing LP, as Master Servicer, Wells Fargo Bank, National
Association, as Co-Trustee, and The Bank of New York, as Trustee. Capitalized
terms used herein shall have the meanings ascribed to such terms in the
Pooling and Servicing Agreement.

          __________________ hereby certifies that he/she is a Servicing
Officer, holding the office set forth beneath his/her name and hereby further
certifies as follows:

          With respect to the Distribution Date in _________ 20[ ] and each
Mortgage Loan set forth in the attached schedule:

          1. A Principal Prepayment in full or in part was received during the
related Prepayment Period;

          2. Any Prepayment Charge due under the terms of the Mortgage Note
with respect to such Principal Prepayment was or was not, as indicated on the
attached schedule using "Yes" or "No", received from the Mortgagor and
deposited in the Certificate Account;

          3. As to each Mortgage Loan set forth on the attached schedule for
which all or part of the Prepayment Charge required in connection with the
Principal Prepayment was waived by the Master Servicer, such waiver was, as
indicated on the attached schedule, based upon:

               (i) the Master Servicer's determination that such waiver would
     maximize recovery of Liquidation Proceeds for such Mortgage Loan, taking
     into account the value of such Prepayment Charge, or

               (ii)(A) the enforceability thereof is limited (1) by
     bankruptcy, insolvency, moratorium, receivership, or other similar law
     relating to creditors' rights generally or (2)

                                     T-1

     due to acceleration in connection with a foreclosure or other involuntary
     payment, or (B) the enforceability is otherwise limited or prohibited by
     applicable law; and

          4. We certify that all amounts due in connection with the waiver of
a Prepayment Charge inconsistent with clause 3 above which are required to be
deposited by the Master Servicer pursuant to Section 3.20 of the Pooling and
Servicing Agreement, have been or will be so deposited.
