                          CONVEYANCE OF MORTGAGE LOANS;
                         REPRESENTATIONS AND WARRANTIES

      SECTION 2.01. Conveyance of Mortgage Loans.

      The Depositor, concurrently with the execution and delivery hereof, does
hereby sell, transfer, assign, set over and convey to the Trustee without

of the Trust Fund. Such assignment includes all interest and principal received
on or with respect to the Mortgage Loans, other than Subsequent Mortgage Loans,
on or after the Cut-off Date (other than Scheduled Payments due on the Mortgage
Loans on or before the Cut-off Date).

      In connection with such assignment, the Depositor does hereby deliver to,
and deposit with, the Trustee, or to the Custodian as the Trustee's designated
agent, the following documents or instruments with respect to each Mortgage Loan
and the Depositor shall, in accordance with Section 2.11, deliver to, and

      order of U.S. Bank National Association, as Trustee for Terwin Mortgage
      Trust 2004-3HE, Asset-Backed Certificates, Series 2004-3HE, without
      recourse" together with all riders thereto. The Mortgage Note shall
      include all intervening endorsements showing a complete chain of the title
      from the originator to the Transferor.

            (C)   Except as provided below and for each Mortgage Loan that is
      not a MERS Loan, the original recorded Mortgage together with all riders
      thereto, with evidence of recording thereon, or, if the original Mortgage
      has not yet been returned from the recording office, a copy of the
      original Mortgage together with all riders thereto certified by the
      Transferor to be true copy of the original of the Mortgage that has been
      delivered for recording in the appropriate recording

<PAGE>

      office of the jurisdiction in which the Mortgaged Property is located and
      in the case of each MERS Loan, the original Mortgage together with all
      riders thereto, noting the presence of the MIN of the Loan and either
      language indicating that the Mortgage Loan is a MOM Loan or if the

      thereon, or a copy of the Mortgage certified by the public recording

      Association, as Trustee for Terwin Mortgage Trust 2004-3HE, Asset-Backed

            (E)   The original policy of title insurance (or a preliminary title
      report, commitment or binder if the original title insurance policy has
      not been received from the title insurance company).

            (F)   Originals of any intervening assignments of the Mortgage, with
      evidence of recording thereon or, if the original intervening assignment
      has not yet been returned from the recording office, a copy of such
      assignment certified to be a true copy of the original of the assignment
      which has been sent for recording in the appropriate jurisdiction in which
      the Mortgaged Property is located.

            (G)   Originals of all assumption and modification agreements, if
      any.

      If in connection with any Mortgage Loan, the Depositor cannot deliver the
Mortgage, Assignments of Mortgage or assumption, consolidation or modification,
as the case may be, with evidence of recording thereon, if applicable,
concurrently with the execution and delivery of this Agreement solely because of
a delay caused by the public recording office where such Mortgage, Assignments
of Mortgage or assumption, consolidation or modification, as the case may be,
has been delivered for recordation, the Depositor shall deliver or cause to be
delivered to the Trustee (or the Custodian) written notice stating that such
Mortgage or assumption, consolidation or modification, as the case may be, has
been delivered to the appropriate public recording office for recordation.
Thereafter, the Depositor shall deliver or cause to be delivered to the Trustee
(or the Custodian) such Mortgage, Assignments of Mortgage or assumption,
consolidation or modification, as the case may be, with evidence of recording
indicated thereon, if applicable, upon receipt thereof from the public recording
office. To the extent any required endorsement is not contained on a Mortgage
Note or an Assignment of Mortgage, the Depositor shall make or cause such
endorsement to be made.

      With respect to any Mortgage Loan, none of the Depositor, the Master
Servicer, the Servicers, the Securities Administrator or the Trustee shall be
obligated to cause to be recorded the Assignment of Mortgage referred to in this
Section 2.01. In the event an Assignment of Mortgage is not recorded, the Master
Servicer or each Servicer, as applicable, shall have no liability for its
failure to receive and act on notices related to such Assignment of Mortgage.

      The ownership of each Mortgage Note, the Mortgage and the contents of the
related Mortgage File is vested in the Trustee on behalf of the
Certificateholders. None of the Depositor, the Master Servicer, the Servicers
nor the Securities Administrator shall take any action inconsistent with such
ownership and shall not claim any ownership interest therein. The Depositor, the
Master Servicer, the Servicers and Securities Administrator shall respond to any
third party inquiries with respect to ownership of the Mortgage Loans by stating
that such ownership is held by the Trustee on behalf of the Certificateholders.
Mortgage documents relating to the Mortgage Loans not delivered to the Trustee
(or

                                      -51-

<PAGE>

the Custodian) are and shall be held in trust by the Master Servicer prior to
the related Servicing Transfer Date and thereafter by the applicable Servicer,
for the benefit of the Trustee as the owner thereof, and the Master Servicer's
or such Servicer's, as applicable, possession of the contents of each Mortgage
File so retained is for the sole purpose of servicing the related Mortgage Loan,
and such retention and possession by the Master Servicer or such Servicer, as
applicable, is in a custodial capacity only. The Depositor agrees to take no
action inconsistent with the Trustee's ownership of the Mortgage Loans, to
promptly indicate to all inquiring parties that the Mortgage Loans have been
sold and to claim no ownership interest in the Mortgage Loans.

      It is the intention of this Agreement that the conveyance of the
Depositor's right, title and interest in and to the Trust Fund pursuant to this
Agreement shall constitute a purchase and sale and not a loan. If a conveyance
of Mortgage Loans from the Seller to the Depositor is characterized as a pledge
and not a sale, then the Depositor shall be deemed to have transferred to the
Trustee all of the Depositor's right, title and interest in, to and under the
obligations of the Seller deemed to be secured by said pledge; and it is the
intention of this Agreement that the Depositor shall also be deemed to have
granted to the Trustee a first priority security interest in all of the
Depositor's right, title, and interest in, to and under the obligations of the
Seller to the Depositor deemed to be secured by said pledge and that the Trustee
shall be deemed to be an independent custodian for purposes of perfection of the
security interest granted to the Depositor. If the conveyance of the Mortgage
Loans from the Depositor to the Trustee is characterized as a pledge, it is the
intention of this Agreement that this Agreement shall constitute a security
agreement under applicable law, and that the Depositor shall be deemed to have
granted to the Trustee a first priority security interest in all of the
Depositor's right, title and interest in, to and under the Mortgage Loans, all
payments of principal of or interest on such Mortgage Loans, all other rights
relating to and payments made in respect of the Trust Fund, and all proceeds of
any thereof. If the trust created by this Agreement terminates prior to the
satisfaction of the claims of any Person in any Certificates, the security
interest created hereby shall continue in full force and effect and the Trustee
shall be deemed to be the collateral agent for the benefit of such Person.

      In addition to the conveyance made in the first paragraph of this Section
2.01, the Depositor does hereby convey, assign and set over to the Trustee for
the benefit of the Certificateholders its rights and interests under the Sale
Agreement, including the Depositor's right, title and interest in the
representations and warranties contained in the Sale Agreement, the rights in
the Transfer Agreement described therein, and the benefit of the repurchase
obligations and the obligation of the Seller contained in the Sale Agreement to
take, at the request of the Depositor or the Trustee, all action on its part
which is reasonably necessary to ensure the enforceability of a Mortgage Loan.
The Trustee hereby accepts such assignment, and shall be entitled to exercise
all rights of the Depositor under the Sale Agreement as if, for such purpose, it
were the Depositor. The foregoing sale, transfer, assignment, set-over, deposit
and conveyance does not and is not intended to result in creation or assumption
by the Trustee of any obligation of the Depositor, the Seller, or any other
Person in connection with the Mortgage Loans or any other agreement or
instrument relating thereto.

      It is agreed and understood by the Depositor, the Servicer and the Trustee
that it is not intended that any Mortgage Loan be included in the Trust that is
either (i) a "High-Cost Home Loan" as defined in the New Jersey Home Ownership
Act effective November 27, 2003; or (ii) a "High-Cost Home Loan" as defined in
the New Mexico Home Loan Protection Act effective January 1, 2004.

      SECTION 2.02. Acceptance by the Trustee of the Mortgage Loans and the Cap
Contract.

      Except as set forth as an exception in the exception report delivered with
the Initial Certification (the "Exception Report") or the Final Certification,
the Trustee accepts its appointment as Trustee hereunder and acknowledges the
Custodian's receipt, subject to the provisions of Section 2.01 and subject

                                      -52-

<PAGE>

to the review described below, of the Mortgage Note for each Mortgage Loan and
delivery of a Mortgage File (but does not acknowledge receipt of all documents
required to be included in such Mortgage File) with respect to each Mortgage
Loan and declares that it holds and will hold such documents and any other
documents constituting a part of the Mortgage Files delivered to it in trust for
the use and benefit of all present and future Certificateholders. The Depositor
will cause the Seller to repurchase any Mortgage Loan to which a material
exception was taken in the Exception Report unless such exception is cured to
the satisfaction of the Trustee within 45 Business Days of the Closing Date (or
the Subsequent Transfer Date with respect to Subsequent Mortgage Loans).

      The Trustee acknowledges receipt of the Cap Contract (a form of which is
attached hereto).

      The Trustee agrees to cause the Custodian to deliver prior to the Closing
Date (or the Subsequent Transfer Date with respect to Subsequent Mortgage Loans)
to the Depositor, the Securities Administrator and each Servicer an Initial
Certification in the form annexed hereto as Exhibit B-1 to Exhibit Q. The
Trustee shall not be under any 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 70 days after the Closing Date (or the Subsequent Transfer
Date with respect to Subsequent Mortgage Loans), the Custodial Agreement
requires the Custodian to deliver to the Depositor, the Securities Administrator
and each Servicer an Interim Certification in the form annexed hereto as Exhibit
B-2 to Exhibit Q, with any applicable exceptions noted thereon.

      Not later than 90 days after the Closing Date (or the Subsequent Transfer
Date with respect to Subsequent Mortgage Loans), the Custodial Agreement
requires the Custodian to deliver to the Depositor, the Securities Administrator
and each Servicer a Final Certification in the form annexed hereto as Exhibit
B-3 to Exhibit Q, with any applicable exceptions noted thereon.

      If, in the course of such review, the Trustee is notified by the Custodian
that any document constituting a part of a Mortgage File does not meet the
requirements of Section 2.01, the Trustee shall cause the Custodian to list such
as an exception in the Final Certification; provided, however, that the Trustee
shall not make any determination as to whether (i) any endorsement is sufficient
to transfer all right, title and interest of the party so endorsing, as
noteholder or assignee thereof, in and to that Mortgage Note or (ii) any
assignment is in recordable form or is sufficient to effect the assignment of
and transfer to the assignee thereof under the mortgage to which the assignment
relates.

      The Seller shall promptly correct or cure such defect within 90 days from
the date it is so notified of such defect and, if the Seller does not correct or
cure such defect within such period, the Seller shall either (i) substitute for
the related Mortgage Loan pursuant to the provisions of Section 2.03(c), or (ii)
purchase such Mortgage Loan from the Trustee within 90 days from the date the
Seller was notified of such defect in writing at the Purchase Price of such
Mortgage Loan; provided, however, that if the cure, substitution or repurchase
of a Mortgage Loan pursuant to this provision is required by reason of a delay
in delivery of any documents by the appropriate recording office, then, provided
such defect does not cause such Mortgage Loan not to be a "qualified mortgage"
within the meaning of Section 860G(a)(3)(A) of the Code (as determined without
regard to Treasury Regulations Section 1.860G-2(a)(3)(iii) or any similar rule
that treats a defective obligation as a "qualified mortgage" for a temporary
period) the Seller shall be given 270 days from the Closing Date (or the
Subsequent Transfer Date with respect to Subsequent Mortgage Loans) to cure such
defect or, subject to the requirements of Section 2.03(c) hereof, substitute
for, or repurchase such Mortgage Loan; and further provided, that the Seller
shall have no liability for recording any Assignment of Mortgage in favor of the
Trustee or for the Seller's failure to

                                      -53-

<PAGE>

record such Assignment of Mortgage, and the Seller shall not be obligated to
repurchase or cure any Mortgage Loan as to which such Assignment of Mortgage is
not recorded. Any such substitution effected more than 90 days after the Closing
Date shall not be effected prior to the delivery to the Custodian of the Opinion
of Counsel required by Section 2.05 hereof and any substitution shall not be
effected prior to the additional delivery to the Custodian of a Request for
Release certifying that such Mortgage Loan is a Replacement Mortgage Loan
substantially in the form of Exhibit I and the Mortgage File for any such
substitute Mortgage Loan. The Purchase Price for any such Mortgage Loan shall be
deposited by the Seller in the Certificate Account on or prior to the Business
Day immediately preceding the Distribution Date in the month following the month
of repurchase and, upon receipt of such deposit and certification with respect
thereto in the form of Exhibit I hereto, the Custodian shall release the related
Mortgage File to the Seller and shall execute and deliver at such entity's
request such instruments of transfer or assignment prepared by such entity, in
each case without recourse, as shall be necessary to vest in such entity, or a
designee, the Trustee's interest in any Mortgage Loan released pursuant hereto.

      The Trustee shall request that the Seller correct or cure such omission,
defect or other irregularity, or substitute a Mortgage Loan pursuant to the
provisions of Section 2.03(c), within 90 days from the date the Seller was
notified of such omission or defect and, if the Seller does not correct or cure
such omission or defect within such period, the Trustee shall require that the
Seller purchase such Mortgage Loan from the Trust Fund within 90 days from the
date the Trustee notified the Seller of such omission, defect or other
irregularity at the Purchase Price of such Mortgage Loan. The Purchase Price for
any Mortgage Loan purchased pursuant to this Section 2.02 shall be paid to the
Master Servicer prior to the related Servicing Transfer Date, and thereafter to
the applicable Servicer and deposited by the Master Servicer or the applicable
Servicer, as applicable, in the Certificate Account or Collection Account, as
appropriate, promptly upon receipt, and, upon receipt by the Trustee of written
notification of such deposit signed by a Servicing Officer, the Trustee, upon
receipt of a Request for Release, shall promptly release to the Seller the
related Mortgage File and the Trustee shall execute and deliver such instruments
of transfer or assignment, without recourse, as shall be requested by the Seller
and necessary to vest in the Seller or its designee, as the case may be, any
Mortgage Loan released pursuant hereto, and the Trustee shall have no further
responsibility with regard to such Mortgage Loan. It is understood and agreed
that the obligation of the Seller to purchase, cure or substitute any Mortgage
Loan as to which a material defect in or omission of a constituent document
exists shall constitute the sole remedy respecting such defect or omission
available to the Trustee on behalf of Certificateholders. The preceding sentence
shall not, however, limit any remedies available to the Certificateholders, the
Depositor, Securities Administrator or the Trustee pursuant to the Sale
Agreement and any Transfer Agreement. The Trustee shall be under no duty or
obligation to inspect, review and examine such documents, instruments,
certificates or other papers to determine that they are genuine, enforceable,
recordable or appropriate to the represented purpose, or that they have actually
been recorded, or that they are other than what they purport to be on their
face. Each Servicer, the Master Servicer, the Securities Administrator and the
Trustee shall keep confidential the name of each Mortgagor except as required by
this Agreement and each Servicer, the Master Servicer, the Securities
Administrator and the Trustee shall not solicit any such Mortgagor for the
purpose of refinancing the related Mortgage Loan; notwithstanding anything
herein to the contrary, the foregoing shall not be construed to prohibit (i)
disclosure of any and all information that is or becomes publicly known, or
information obtained by Trustee from sources other than the other parties
hereto, (ii) disclosure of any and all information (A) if required to do so by
any applicable law, rule or regulation, (B) to any government agency or
regulatory body having or claiming authority to regulate or oversee any respects
of Trustee's business or that of its affiliates, (C) pursuant to any subpoena,
civil investigation demand or similar demand or request of any court, regulatory
authority, arbitrator or arbitration to which Trustee or any affiliate or an
officer, director, employer or shareholder thereof is a party or (D) to any
affiliate, independent or internal auditor, agent, employee or attorney of
Trustee having a need to know the same, provided that Trustee advises such
recipient of the confidential nature of the information being disclosed, or
(iii) any other disclosure authorized by the Depositor or Master Servicer.

      hold its properties and to conduct its business as now conducted by it and
      to enter into and perform its obligations under this Agreement and the
      Sale Agreement.

            (iii) 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 the Sale Agreement and
      has duly authorized, by all necessary corporate action on its part, the
      execution, delivery and performance of this Agreement and the Sale
      Agreement; and this Agreement and the Sale 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.

            (iv)  The execution and delivery of this Agreement and the Sale
      Agreement by the Depositor, the consummation of the transactions
      contemplated by this Agreement and the Sale 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 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.

            (v)   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 and the Sale Agreement or the ability of the Depositor to
      perform its obligations under this Agreement and the Sale Agreement in
      accordance with the terms hereof.

            (vi)  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 and the Sale Agreement or the consummation of the transactions
      contemplated hereby, or if any such consent, approval, authorization or
      order

                                      -55-

      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 Subsequent Transfer Date with respect to
      Subsequent Mortgage Loans), and following the transfer of the Mortgage
      Loans to it by the Seller, the Depositor had good title to the Mortgage
      Loans and the Mortgage Notes were subject to no offsets, claims, liens,
      mortgage, pledge, charge, security interest, defenses or counterclaims.

            (b)   The representations and warranties of each Transferor with
respect to the related Mortgage Loans in the applicable Transfer Agreement,
which have been assigned to the Trustee hereunder, were made as of the date
specified in the applicable Transfer Agreement (or underlying agreement, if such
Transfer Agreement is in the form of an assignment of a prior agreement). To the
extent that any fact, condition or event with respect to a Mortgage Loan
constitutes a breach of both (i) a representation or warranty of the applicable
Transferor under the applicable Transfer Agreement and (ii) a representation or
warranty of the Seller under the Sale Agreement, the obligations of the Seller
under the Sale Agreement shall be enforced and to the extent the Seller does not
fulfill its contracted obligations then the obligations of the applicable
Transferor shall be enforced under any applicable representation or warranty
made by it. The Trustee further acknowledges that the Depositor shall have no
obligation or liability with respect to any breach of any representation or
warranty with respect to the Mortgage Loans under any circumstances.

            (c)   Upon discovery by any of the Depositor, the Master Servicer,
the Servicers, the Securities Administrator or the Trustee of a breach of any of
such representations and warranties that adversely and materially affects the
value of the related Mortgage Loan, prepayment charges or the interests of the
Certificateholders, the party discovering such breach shall give prompt written
notice to the other parties. Within 90 days of the discovery of such breach of
any representation or warranty, the applicable Transferor or the Seller, as
applicable, shall either (a) cure such breach in all material respects, (b)
repurchase such Mortgage Loan or any property acquired in respect thereof from
the Trustee at the Purchase Price or (c) within the two year period following
the Closing Date, substitute a Replacement Mortgage Loan for the affected
Mortgage Loan. In the event of discovery of a breach of any representation and
warranty of any Transferor or the Seller, the Trustee's rights shall be enforced
under the applicable Transfer Agreement and the Sale Agreement for the benefit
of Certificateholders. If a breach of the representations and warranties set
forth in the Transfer Agreement hereof exists solely due to the unenforceability
of a prepayment charge, the Trustee or the other party having notice thereof
shall notify the applicable Servicer thereof and not seek to enforce the
repurchase remedy provided for herein unless such Mortgage Loan is not current.
In the event of a breach of the representations and warranties with respect to
the Mortgage Loans set forth in a Transfer Agreement, the Trustee shall enforce
the right of the Trust Fund to be indemnified for such breach of representation
and warranty. In the event that such breach relates solely to the
unenforceability of a prepayment charge, amounts received in respect of such
indemnity up to the amount of such prepayment charge shall be distributed
pursuant to Section 5.05(j). As provided in the Sale Agreement, if the
Transferor substitutes for a Mortgage Loan for which there is a breach of any
representations and warranties in the related Transfer Agreement which adversely
and materially affects the value of such Mortgage Loan and such substitute
mortgage loan is not a Replacement Mortgage Loan, under the terms of the Sale
Agreement, the Seller will, in exchange for such substitute Mortgage Loan, (i)
provide the applicable Purchase Price for the affected Mortgage Loan or (ii)
within two years of the Closing Date, substitute such affected Mortgage Loan
with a Replacement Mortgage Loan. Any such substitution shall not be effected
prior to the additional delivery to the Trustee of a Request for Release
substantially in the form of Exhibit I and shall not be effected unless it is
within two years of the Startup Date. The Seller indemnifies and holds the Trust
Fund, the Trustee, the Securities Administrator, the Depositor, the Master
Servicer, each Servicer and each Certificateholder harmless against any and all
taxes, claims, losses, penalties, fines, forfeitures, reasonable legal fees and
related costs, judgments, and any other costs, fees and expenses that the Trust
Fund, the Trustee, the Securities

                                      -56-

<PAGE>

Administrator, the Depositor, the Master Servicer, each Servicer and any
Certificateholder may sustain in connection with any actions of the Seller
relating to a repurchase of a Mortgage Loan other than in compliance with the
terms of this Section 2.03 and the Sale Agreement, to the extent that any such
action causes (i) any federal or state tax to be imposed on the Trust Fund or
any REMIC provided for herein, including without limitation, any federal tax
imposed on "prohibited transactions" under Section 860F(a)(1) of the Code or on
"contributions after the startup date" under Section 860(d)(1) of the Code, or
(ii) any REMIC created hereunder to fail to qualify as a REMIC at any time that
any Certificate is outstanding. In furtherance of the foregoing, if the
Transferor or the Seller, as applicable, is not a member of MERS and repurchases
a Mortgage Loan which is registered on the MERS System, the Transferor or the
Seller, as applicable, at its own expense and without any right of
reimbursement, shall cause MERS to execute and deliver an assignment of the
Mortgage in recordable form to transfer the Mortgage from MERS to the Transferor
or the Seller, as applicable, and shall cause such Mortgage to be removed from
registration on the MERS System in accordance with MERS' rules and regulations.

      With respect to any Mortgage Loan repurchased by the Seller pursuant to
the Sale Agreement or by any Transferor pursuant to the applicable Transfer
Agreement, the principal portion of the funds received by the Securities
Administrator, in respect of such repurchase of a Mortgage Loan will be
considered a Principal Prepayment and shall be deposited in the Certificate
Account pursuant to Section 3.05. The Trustee, upon receipt of notice from the
Securities Administrator of its receipt of the full amount of the Purchase Price
for a Deleted Mortgage Loan, or upon receipt of the Mortgage File for a
Replacement Mortgage Loan substituted for a Deleted Mortgage Loan, shall release
or cause to be released and reassign to the Seller or the applicable Transferor,
as applicable, the related Mortgage File for the Deleted Mortgage Loan and shall
execute and deliver such instruments of transfer or assignment, in each case
without recourse, representation or warranty, as shall be necessary to vest in
such party or its designee or assignee title to any Deleted Mortgage Loan
released pursuant hereto, free and clear of all security interests, liens and
other encumbrances created by this Agreement, which instruments shall be
prepared by the Seller, and neither the Trustee nor the Securities Administrator
shall have any further responsibility with respect to the Mortgage File relating
to such Deleted Mortgage Loan.

      With respect to each Replacement Mortgage Loan to be delivered to the
Trustee (or the Custodian) pursuant to the terms of this Article II in exchange
for a Deleted Mortgage Loan: (i) the applicable Transferor or the Seller, as
applicable, must deliver to the Trustee (or its custodian) the Mortgage File for
the Replacement Mortgage Loan containing the documents set forth in Section 2.01
along with a written certification certifying as to the Mortgage Loan satisfying
all requirements under the definition of Replacement Mortgage Loan and the
delivery of such Mortgage File and containing the granting language set forth in
Section 2.01; and (ii) the Depositor will be deemed to have made, with respect
to such Replacement Mortgage Loan, each of the representations and warranties
made by it with respect to the related Deleted Mortgage Loan. The Custodian
shall review the Mortgage File with respect to each Replacement Mortgage Loan
and certify to the Depositor that all documents required by Section 2.01 have
been executed and received.

      For any month in which the Seller substitutes one or more Replacement
Mortgage Loans for one or more Deleted Mortgage Loans, the Seller will determine
the amount (if any) by which the aggregate principal balance of all such
Replacement Mortgage Loans as of the date of substitution and the aggregate
prepayment penalties with respect to such Replacement Mortgage Loans is less
than the aggregate Stated Principal Balance (after application of the principal
portion of the Scheduled Payment due in the month of substitution) and aggregate
prepayment penalties 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 deposited into the Certificate
Account by the Seller on 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.

                                      -57-

<PAGE>

      Notwithstanding any other provision of this Agreement, the right to
substitute Mortgage Loans pursuant to this Article II shall be subject to the
additional limitations that no substitution of a Replacement Mortgage Loan for a
Deleted Mortgage Loan shall be made unless the Securities Administrator shall
have received an Opinion of Counsel (at the expense of the party seeking to make
the substitution) that, under current law, such substitution will not (A) affect
adversely the status of any REMIC established hereunder as a REMIC, or of the
related "regular interests" as "regular interests" in any such REMIC, or (B)
cause any such REMIC to engage in a "prohibited transaction" or prohibited
contribution pursuant to the REMIC Provisions.

      The Trustee shall amend the Mortgage Loan Schedule to reflect the removal
of such Deleted Mortgage Loan from the terms of this Agreement and the
substitution of the Replacement Mortgage Loan or Replacement Mortgage Loans.
Upon such substitution by the Seller, such Replacement Mortgage Loan or
Replacement Mortgage Loans shall constitute part of the Mortgage Pool and shall
be subject in all respects to the terms of this Agreement and the Sale
Agreement, including all applicable representations and warranties thereof
included in the Sale Agreement as of the date of substitution.

            (d)   It is understood and agreed that the representations,
warranties and indemnification (i) set forth in this Section 2.03, (ii) of the
Seller and the Depositor set forth in the Sale Agreement and assigned to the
Trustee by the Depositor hereunder and (iii) of each Transferor, assigned by the
Seller to the Depositor pursuant to the Sale Agreement and assigned to the
Trustee by the Depositor hereunder shall each survive delivery of the Mortgage
Files and the Assignment of Mortgage of each Mortgage Loan to the Trustee and
shall continue throughout the term of this Agreement.

            (e)   The Depositor shall deliver a copy of the Mortgage Loan
Schedule to each Servicer on the Closing Date (or the Subsequent Transfer Date
with respect to Subsequent Mortgage Loans).

not "Qualified Mortgages".

      Upon discovery by the Depositor, the Master Servicer, either Servicer, the
Securities Administrator, the Backup 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 Depositor shall, at the
Depositor's option, either (i) substitute, if the conditions in Section 2.03(c)
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,
upon the written direction of the Depositor, shall reconvey to the Depositor the
Mortgage Loan to be released pursuant hereto in the same manner, and on the same

      SECTION 2.07. REMIC Elections.

            (a)   The Depositor hereby instructs and authorizes the Securities
Administrator on behalf of the Trustee to make an appropriate election to treat
each of REMIC 1, REMIC 2, REMIC 3 and REMIC 4 as a REMIC for federal income tax
purposes. The Trustee, upon the written direction of the Securities
Administrator, shall sign the returns providing for such elections and such
other tax or information returns which are required to be signed by the Trustee
under applicable law. This Agreement shall be construed so as to carry out the
intention of the parties that each of REMIC 1, REMIC 2, REMIC 3 and REMIC 4 be
treated as a REMIC at all times prior to the date on which the Trust Fund is
terminated.

            (b)   The Preliminary Statement sets forth the designations and
"latest possible maturity date" for federal income tax purposes of all interests
created hereby. The "Startup Date" for purposes of the REMIC Provisions shall be
the Closing Date. Each REMIC's fiscal year shall be the calendar year.

      REMIC 1 shall consist of all of the assets of the Trust Fund other than
(i) the interests issued by REMIC 1, REMIC 2, REMIC 3 and REMIC 4, (ii) the
rights to receive Prepayment Penalties, amounts paid by the Servicer, the Seller
or any Transferor in respect of Prepayment Penalties pursuant to this Agreement
or a Transfer Agreement, as applicable and amounts received in respect of any
indemnification paid as a result of a Prepayment Penalty being unenforceable in
breach of the representations and warranties set forth in a Transfer Agreement,
(iii) the grantor trusts described in Section 2.07 hereof, (iv) the Cap Contract
and Cap Contract Account, (v) the Pre-Funding Account and (vi) the Capitalized
Interest Account. REMIC 1 shall issue the REMIC 1 Regular Interests which shall
be designated as regular interests of such REMIC and shall issue the Class LT1-R
Interest that shall be designated as the sole class of residual interest in
REMIC 1. Each of the REMIC 1 Regular Interests shall have the characteristics
set forth in its definition and this Section 2.07.

      The assets of REMIC 2 shall be the REMIC 1 Regular Interests. The REMIC 2
Regular Interests shall be designated as the regular interests in REMIC 2 and
the Class LT2-R Interest shall be designated as the sole class of residual
interest in REMIC 2. Each of the REMIC 2 Regular Interests shall have the
characteristics set forth in its definition and this Section 2.07.

      The assets of REMIC 3 shall be the REMIC 2 Regular Interests (other than
the REMIC 2 IO Interests). The REMIC 3 Regular Interests shall be designated as
the regular interests in REMIC 3 and the Class LT3-R Interest shall be
designated as the sole class of residual interest in REMIC 3. Each of the REMIC
3 Regular Interests shall have the characteristics set forth in its definition
and this Section 2.07.

      The assets of REMIC 4 shall be the REMIC 3 Regular Interests and the REMIC
2 IO Interests. The REMIC 4 Regular Interests shall be designated as the regular
interests in REMIC 4 and the REMIC 4 Residual Interest shall be designated as
the sole class of residual interest in REMIC 4. For federal income tax purposes,
the interest rate on each REMIC 4 Regular Interest (other than the REMIC 4 XN
Interest and the Interest Only Certificates) and on the REMIC 4 Residual
Interest shall be subject to a cap equal to the Adjusted Net WAC.

      The beneficial ownership of the Class LT1-R Interest, the Class LT2-R
Interest, the Class LT3-R Interest and the REMIC 4 Residual Interest shall be
represented by the Class R Certificate. None of the Class LT1-R Interest, the
Class LT2-R Interest and the Class LT3-R Interest shall have a principal balance
or bear interest.

            (c)   The "tax matters person" with respect to each REMIC for
purposes of the REMIC Provisions shall be the beneficial owner of the Class R
Certificate; provided, however, that the

                                      -63-

<PAGE>

Holder of a Class R Certificate, by its acceptance thereof, irrevocably appoints
the Securities Administrator as its agent and attorney-in-fact to act as "tax
matters person" with respect to each REMIC for purposes of the REMIC Provisions.
If there is more than one beneficial owner of the Class R Certificate, the "tax
matters person" shall be the Person with the greatest percentage interest in the
Class R Certificate and, if there is more than one such Person, shall be
determined under Treasury regulation Section 1.860F-4(d) and Treasury regulation
Section 301.6231(a)(7)-1.

            (d)   It is intended that the rights of the Class A-1-A
Certificates, Class A-1-B Certificates, Class R Certificate, Class M-1
Certificates, Class M-2 Certificates, Class M-3 Certificates, Class B-1
Certificates, Class B-2 Certificates and Class B-3 Certificates to receive
payments in respect of Excess Interest shall be treated as a right in interest
rate cap contracts written in favor of the holders of the Class A-1-A
Certificates, Class A-1-B Certificates, Class R Certificate, Class M-1
Certificates, Class M-2 Certificates, Class M-3 Certificates, Class B-1
Certificates, Class B-2 Certificates and Class B-3 Certificates by the grantor
trust or partnership described below in Section 2.07(e), and such shall be
accounted for as property held separate and apart from the regular interests in
REMIC 4 held by the holders of the Class A-1-A Certificates, Class A-1-B
Certificates, Class M-1 Certificates, Class M-2 Certificates, Class M-3
Certificates, Class B-1 Certificates, Class B-2 Certificates and Class B-3
Certificates and the residual interest in REMIC 4 held by the holder of the
Class R Certificate. For information reporting requirements, the rights of the
Class A-1-A, Class A-1-B, Class R, Class M-1, Class M-2, Class M-3, Class B-1,
Class B-2 and Class B-3 Certificates to receive payments in respect of Excess
Interest shall be assumed to have zero value or a de minimis value. This
provision is intended to satisfy the requirements of Treasury Regulations
Section 1.860G-2(i) for the treatment of property rights coupled with REMIC
interests to be separately respected and shall be interpreted consistently with
such regulation. On each Distribution Date, to the extent that any of the Class
A-1-A Certificates, Class A-1-B Certificates, Class R Certificate, M-1
Certificates, Class M-2 Certificates, Class M-3 Certificates, Class B-1
Certificates, Class B-2 Certificates and Class B-3 Certificates receive payments
of Excess Interest (other than from payments received in respect of the Cap
Contract), such amounts will be treated as distributed by REMIC 4 on the REMIC 4
XN Interest and then paid to the relevant Class of Certificates pursuant to the
related interest rate cap contract.

            (e)   Except as described in the following sentence, for federal
income tax purposes, the Class N and Class X Certificates shall represent
beneficial ownership of a grantor trust under subpart E, Part I of subchapter J
of the Code that holds the uncertificated REMIC 4 XN Interest, the Cap Contract,
the Cap Contract Account and the rights to receive Prepayment Penalties, amounts
paid by the Servicer, the Seller or any Transferor in respect of Prepayment
Penalties pursuant to this Agreement or a Transfer Agreement, as applicable and
amounts received in respect of any indemnification paid as a result of a
Prepayment Penalty being unenforceable in breach of the representations and
warranties set forth in a Transfer Agreement, and is treated as obligated to
make payments in respect of the interest rate cap contracts described in this
Section 2.07. If the Class N and Class X Certificates are beneficially owned by
more than one Person, and such Persons do not hold both the Class N and Class X
Certificates proportionately, then each such Person shall be treated as owning
an interest in a partnership that owns the uncertificated REMIC 4 XN Interest,
the Cap Contract, the Cap Contract Account and the rights to receive Prepayment
Penalties, amounts paid by the Servicer, the Seller or any Transferor in respect
of Prepayment Penalties pursuant to this Agreement or a Transfer Agreement, as
applicable and amounts received in respect of any indemnification paid as a
result of a Prepayment Penalty being unenforceable in breach of the
representations and warranties set forth in a Transfer Agreement. For federal
income tax purposes, as long as the condition described in the preceding
sentence is not satisfied, the Securities Administrator shall treat the grantor
trust as beneficially owned by the holder of the Class N and Class X
Certificates and shall treat such portion of the Trust Fund as a grantor trust
under subpart E, Part I of subchapter J of the Code. If the condition described
in the second preceding sentence is satisfied, the Trustee shall treat the treat
the uncertificated REMIC 4 XN Interest, the Cap Contract, the Cap

                                      -64-

<PAGE>

Contract Account and the rights to receive Prepayment Penalties, amounts paid by
the Servicer, the Seller or any Transferor in respect of Prepayment Penalties
pursuant to this Agreement or a Transfer Agreement, as applicable and amounts
received in respect of any indemnification paid as a result of a Prepayment
Penalty being unenforceable in breach of the representations and warranties set
forth in a Transfer Agreement, as owned by a partnership, the beneficial owners
of which are the beneficial owners of the Class N and Class X Certificates. The
Securities Administrator shall (i) file all required tax and information returns
with respect to the ownership of the REMIC 4 XN Interest, the Cap Contract, the
Cap Contract Account and the rights to receive Prepayment Penalties, amounts
paid by the Servicer, the Seller or any Transferor in respect of Prepayment
Penalties pursuant to this Agreement or a Transfer Agreement, as applicable and
amounts received in respect of any indemnification paid as a result of a
Prepayment Penalty being unenforceable in breach of the representations and
warranties set forth in a Transfer Agreement (including partnership returns if
the Class N and Class X Certificates are beneficially owned by more than one
Person and such Persons do not hold both the Class N and Class X Certificates
proportionately), (ii) furnish or cause to be furnished to the holders of the
Class N and Class X Certificates information regarding their allocable share, if
any, of the income with respect to the REMIC 4 XN Interest, the Cap Contract,
the Cap Contract Account and the rights to receive Prepayment Penalties, amounts
paid by the Servicer, the Seller or any Transferor in respect of Prepayment
Penalties pursuant to this Agreement or a Transfer Agreement, as applicable and
amounts received in respect of any indemnification paid as a result of a
Prepayment Penalty being unenforceable in breach of the representations and
warranties set forth in a Transfer Agreement, (iii) file or cause to be filed
with the Internal Revenue Service Form 1041 (together with any necessary
attachments) and such other forms as may be applicable with respect to the
grantor trust described herein and (iv) comply with such information reporting
obligations as may apply with respect to payments deemed to be in respect of the
interest rate cap contracts described in this Section 2.07.

            (f)   On each Distribution Date, payments in respect of principal
shall be deemed made to and Realized Losses deemed allocated to the REMIC 1
Regular Interests in the same amounts as such payments are made or Realized
Losses are allocated to the Corresponding Certificates. Principal received on
the Mortgage Loans and Realized Losses with respect to principal on the Mortgage
Loans that are not paid or allocated to Corresponding Certificates with respect
to the REMIC 1 Regular Interests shall be treated as distributed with respect to
the Class LT1-C Interest until its principal balance has been reduced to zero.
The principal balance of the REMIC 1 Regular Interests will be increased on each
Distribution Date in an amount equal to any increase on such Distribution Date
in the Certificate Principal Balance of the Corresponding Certificates pursuant
to the last sentence of the definition of "Certificate Principal Balance."

            (g)   On each Distribution Date, payments in respect of principal
shall be deemed made to and Realized Losses deemed allocated to the REMIC 2
Regular Interests in the same amounts as such payments are made or Realized
Losses are allocated to the Corresponding Certificates. Principal received on
the Mortgage Loans and Realized Losses with respect to principal on the Mortgage
Loans that are not paid or allocated to Corresponding Certificates with respect
to the REMIC 2 Regular Interests shall be treated as distributed with respect to
the Class LT2-C Interest until its principal balance has been reduced to zero.
The principal balance of the REMIC 2 Regular Interests will be increased on each
Distribution Date in an amount equal to any increase on such Distribution Date
in the Certificate Principal Balance of the Corresponding Certificates pursuant
to the last sentence of the definition of "Certificate Principal Balance.

            (h)   All payments in respect of the REMIC 2 Regular Interests
(other than the REMIC 2 IO Interests) shall be paid to the REMIC 3 Regular
Interests until the principal balance of all such interests have been reduced to
zero and any losses allocated to such interests have been reimbursed.

                                      -65-

<PAGE>

Any excess amounts shall be distributed to the Class LT3-R Interest. On each
Distribution Date, an amount equal to 50% of the increase in the
Overcollateralization Amount shall be payable as a reduction of the principal
amounts of the REMIC 3 Marker Interests (with such amount allocated among the
REMIC 3 Marker Interests so that each REMIC 3 Marker Interest will have its
principal reduced by an amount equal to 50% of any increase in the
Overcollateralization Amount that results in a reduction in the principal
balance of its Corresponding REMIC 4 Interests) and will be accrued and added to
the principal balance of the Class LT3-X Interest. All payments of scheduled
principal and prepayments of principal on the Mortgage Loans shall be allocated
50% to the Class LT3-X Interest and 50% to the REMIC 3 Marker Interests (with
principal payments allocated to each of the REMIC 3 Marker Interests in an
amount equal to 50% of the principal amounts distributed to the Corresponding
REMIC 4 Interests in reduction of their principal amounts). Notwithstanding the
preceding sentence, an amount equal to the principal payments that result in a
reduction in the Overcollateralization Amount shall be treated as payable
entirely to the Class LT3-X Interest. Realized Losses, other than Realized
Losses that are not applied against overcollateralization or the principal
amount of the Class M, Class X or Class B Certificates, shall be applied to the
REMIC 3 Marker Interests and the Class LT3-X Interest so that after all
distributions have been made on each Distribution Date (i) the principal balance
of each of the REMIC 3 Marker Interests is equal to 50% of the principal balance
of the Corresponding REMIC 4 Interests and (ii) the principal balance of the
Class LT3-X Interest is equal to the sum of (x) 50% of the aggregate principal
balance of the REMIC 2 Regular Interests and (y) 50% of the
Overcollateralization Amount. Each REMIC 2 Marker Interest shall be entitled to
receive an amount equal to 50% of all amounts distributed to the Corresponding
REMIC 4 Interest in respect of unreimbursed amounts of Realized Losses. The
Class LT3-X Interest shall be entitled to receive all other amounts distributed
to the Certificates in respect of unreimbursed amounts of Realized Losses.

      All payments of scheduled principal and prepayments on the Mortgage Loans,
and Realized Losses on the Mortgage Loans, shall be allocated among the REMIC 4
Regular Interests in the same manner as such payments or Realized Losses are
allocated to the Related Certificates (treating the Class N Certificates and the
Class X Certificates as related to the REMIC 4 XN Interest for this purpose).
Each REMIC 4 Regular Interest shall be entitled to receive all amounts
distributed to the Related Certificates in respect of unreimbursed amounts of
Realized Losses (treating the Class N Certificates and the Class X Certificates
as related to the REMIC 4 XN Interest for this purpose).

      In the event that any REMIC provided for herein fails to qualify as a
REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as a
result of a prohibited transaction or prohibited contribution under the REMIC
Provisions due to the negligent performance by a Servicer of its duties and
obligations set forth herein, such Servicer shall indemnify the Trustee, the
Securities Administrator, the Master Servicer and the Trust Fund against any and
all Losses resulting from such negligence; provided, however, that such Servicer
shall not be liable for any such Losses attributable to the action or inaction
of the Securities Administrator, the Depositor, the Trustee or the Holder of
such Class R Certificate, as applicable, nor for any such Losses resulting from
misinformation provided by the Holder of such Class R Certificate on which such
Servicer has relied. The foregoing shall not be deemed to limit or restrict the
rights and remedies of the Holder of such Class R Certificate now or hereafter
existing at law or in equity. Notwithstanding the foregoing, however, in no
event shall such Servicer have any liability (1) for any action or omission that
is taken in accordance with and in compliance with the express terms of, or
which is expressly permitted by the terms of, this Agreement, (2) for any Losses
other than arising out of a negligent performance by such Servicer of its duties
and obligations set forth herein, and (3) for any special or consequential
damages to Certificateholders (in addition to payment of principal and interest
on the Certificates).

      In the event that any REMIC provided for herein fails to qualify as a
REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as a
result of a prohibited transaction or prohibited

                                      -66-

contribution under the REMIC Provisions due to the negligent performance by the
Securities Administrator of its duties and obligations set forth herein, the
Securities Administrator shall indemnify the Trust Fund against any and all
Losses resulting from such negligence; provided, however, that the Securities
Administrator shall not be liable for any such Losses attributable to the action
or inaction of the applicable Servicer, the Depositor, the Trustee or the Holder
of such Class R Certificate, as applicable, nor for any such Losses resulting
from misinformation provided by the Holder of such Class R Certificate on which
the Securities Administrator has relied. The foregoing shall not be deemed to
limit or restrict the rights and remedies of the Holder of such Class R
Certificate now or hereafter existing at law or in equity. Notwithstanding the
foregoing, however, in no event shall the Securities Administrator have any
liability (1) for any action or omission that is taken in accordance with and in
compliance with the express terms of, or which is expressly permitted by the
terms of, this Agreement, (2) for any Losses other than arising out of a
negligent performance by the Securities Administrator of its duties and
obligations set forth herein, and (3) for any special or consequential damages
to Certificateholders (in addition to payment of principal and interest on the
Certificates).

      The Master Servicer hereby covenants to each of the other parties to this
Agreement as follows:

            (a)   the Master Servicer shall comply in the performance of its

Servicer is acting as servicer hereunder;

            (b)   no written information, certificate of an officer, statement
furnished in writing or written report delivered to the Depositor, either
Servicer or the Trustee, any affiliate of the Depositor, each Servicer, the
Securities Administrator, the Backup Servicer or the Trustee and prepared by the
Master Servicer pursuant to this Agreement will be inaccurate in any material
respect, provided, however, that the Master Servicer shall not be responsible
for inaccurate information provided to it by third parties.

Master Servicer, the Securities Administrator, the Backup Servicer or the
Trustee, any affiliate of the Depositor, the Master Servicer, the Securities
Administrator, the Backup Servicer or the Trustee and prepared by each Servicer
pursuant to this Agreement will be inaccurate in any material respect, provided,
however, that such Servicer shall not be responsible for inaccurate information

      SECTION 2.11. Conveyance of Subsequent Mortgage Loans.

            (a)   Subject to the conditions set forth in paragraph (b) below, in
consideration of the remittance on each Subsequent Transfer Date to or upon the
order of the Depositor of all or a portion of the balance of funds in the
Pre-Funding Account, which constitute the purchase price for the related
Subsequent Mortgage Loans, as described in the next paragraph, the Depositor
shall on such Subsequent Transfer Date sell, transfer, assign, set over and
convey without recourse all of the right, title and interest of the Depositor in
and to (i) the Subsequent Mortgage Loans identified on the Mortgage Loan
Schedule attached to the related Subsequent Transfer Instrument delivered by the
Depositor on such Subsequent Transfer Date, including all interest and principal
received on or with respect to the Subsequent Mortgage Loans so assigned and the
Depositor shall deliver to, and deposit with, the Trustee all items with respect
to such Subsequent Mortgage Loans to be delivered pursuant to Section 2.01;
provided, however, that the Depositor reserves and retains all right, title and
interest in and to principal received and interest accruing on the Subsequent
Mortgage Loans on or prior to the related Subsequent Cut-off Date. The transfer
to the Trustee for deposit in the Mortgage Pool by the Depositor of the
Subsequent Mortgage Loans identified on the Mortgage Loan Schedule shall be
absolute and is intended by the Depositor, the Servicer, the Trustee and the
Certificateholders to constitute and to be treated as a sale of the Subsequent
Mortgage Loans by the Depositor to the Trust Fund. The related Mortgage File for
each Subsequent Mortgage Loan shall be delivered to the Trustee or to the
Custodian (as the duly appointed agent of the Trustee) on or before the related
Subsequent Transfer Date. The Trustee shall amend the Mortgage Loan Schedule to
reflect the removal of such Subsequent Mortgage Loans. After the Subsequent
Transfer Date, the Subsequent Mortgage Loans shall constitute part of the
Mortgage Pool and shall be subject in all respects to the terms of this
Agreement and the Sale Agreement, including all applicable representations and
warranties thereof included in the Sale Agreement as of the date of
substitution.

      Upon delivery by the Depositor of timely Addition Notices, and subject to
satisfaction of the conditions set forth in paragraphs (c) and (d) below, the
Trust Fund shall be obligated to purchase, in accordance with the provisions of
this Agreement, Subsequent Mortgage Loans offered for sale by the Depositor
during the Funding Period (subject to the limitation that the aggregate purchase
price for such Subsequent Mortgage Loans may not exceed the Original Pre-Funded
Amount). The purchase price paid by the Trust Fund for the Subsequent Mortgage
Loans on each Subsequent Transfer Date shall be one-hundred percent (100%) of
the aggregate Stated Principal Balance of the Subsequent Mortgage Loans so
transferred (as identified on the Mortgage Loan Schedule provided by the
Depositor) as of the related Subsequent Cut-off Date. On each Subsequent
Transfer Date, the aggregate purchase price for all Subsequent Mortgage Loans
purchased on such date shall be withdrawn by the Securities Administrator from
the Pre-Funding Account and paid to the Depositor. Thereafter, the Pre-Funded
Amount will equal the Original Pre-Funded Amount reduced by the purchase price
paid for Subsequent Mortgage Loans. This Agreement shall constitute a
fixed-price purchase contract in accordance with Section 860G(a)(3)(A)(ii) of
the Code.

            (b)   The Depositor shall transfer to the Trustee for deposit in the
Mortgage Pool the Subsequent Mortgage Loans and the other property and rights
related thereto as described in paragraph (a) above, and the Securities
Administrator shall release funds from the Pre-Funding Account, only upon the
satisfaction of each of the following conditions on or prior to the related
Subsequent Transfer Date:

                  (i)   the Depositor shall have provided the Trustee, the
Securities Administrator and the Servicer with a timely Addition Notice;

                  (ii)  the Depositor shall have delivered to the Trustee (with
a copy to the Securities Administrator) a duly executed Subsequent Transfer
Instrument, which shall include a Mortgage Loan Schedule listing the Subsequent
Mortgage Loans, and the Depositor shall have delivered

                                      -68-

Administrator, the Trustee and the Servicer at least three Business Days prior
to the related Subsequent Transfer Date;

                  (iii) as of each Subsequent Transfer Date, as evidenced by
delivery of the Subsequent Transfer Instrument, the Depositor shall not be
insolvent nor shall it have been rendered insolvent by such transfer nor shall
it be aware of any pending insolvency;

                  (iv)  the Funding Period shall not have terminated;

                  (v)   the Depositor shall have delivered to the Trustee (with
a copy to the Securities Administrator) a Subsequent Transfer Instrument
confirming the satisfaction of the conditions precedent specified in this
Section 2.11 and, pursuant to the Subsequent Transfer Instrument, assigned to
the Trustee without recourse for the benefit of the Certificateholders all the
right, title and interest of the Depositor, in, to and under the Subsequent
Mortgage Loan Purchase Agreement, to the extent of the Subsequent Mortgage
Loans;

                  (vi)  the Depositor shall have delivered to the Trustee a
letter (with copies provided to each Rating Agency and the Securities
Administrator), which the Trustee may rely on, including for purposes of

the Trustee on the Closing Date regarding the true sale of the Subsequent
Mortgage Loans; and

                  (viii) the Trustee shall have delivered to the Depositor an
Opinion of Counsel addressed to the Depositor and the Rating Agencies with
respect to the Subsequent Transfer Instrument substantially in the form of the
Opinion of Counsel delivered to the Depositor on the Closing Date regarding

Mortgage Loan on any Subsequent Transfer Date is subject to the satisfaction of
the conditions set forth in paragraph (d) below and the accuracy of the
following representations and warranties with respect to such Subsequent
Mortgage Loan determined as of the Subsequent Cut-off Date (or such other date

            (d)   Following the purchase of the Subsequent Mortgage Loans by the
Trust Fund, the Mortgage Loans (including the Subsequent Mortgage Loans) will
have characteristics that, as of the Subsequent Cut-off Date, are not materially
inconsistent with the Initial Mortgage Loans.

      Notwithstanding the foregoing, any Subsequent Mortgage Loan may be
rejected by either Rating Agency if the inclusion of any such Subsequent
Mortgage Loan would adversely affect the ratings of any Class of Certificates.

            (e)   Each Subsequent Transfer Date shall be on or between the first
and fifteenth day of the calendar month in which the Subsequent Transfer Date
occurs. To the extent that a transfer is made between the first and the
fifteenth day the applicable Servicer is responsible for submitting a revised
servicer report pursuant to Section 3.24 with respect to those Subsequent
Transfer Loans on the fifteenth day of such calendar month.

      SECTION 2.12. Permitted Activities of the Trust. The Trust is created for
the object and purpose of engaging in the Permitted Activities.

      SECTION 2.13. Qualifying Special Purpose Entity. For purposes of SFAS 140,
the parties hereto intend that the Trust Fund shall be treated as a "qualifying
special purpose entity" as such term is used in SFAS 140 and any successor rule
thereto and its power and authority as stated in Section 2.11 of this Agreement
shall be limited in accordance with paragraph 35 or SFAS 140.

                                   ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

      SECTION 3.01. Servicers to Service Mortgage Loans.

      For and on behalf of the Certificateholders, each Servicer shall service
and administer the Mortgage Loans in accordance with Accepted Servicing
Practices. In connection with such servicing and administration, each Servicer
shall have full power and authority, acting alone and/or through subservicers as
provided in Section 3.02 hereof, to do or cause to be done any and all things
that it may deem necessary or desirable in connection with such servicing and
administration, including but not limited to, the power and authority, 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 and other Liquidation Proceeds and (iv) subject to Section 3.12(a), to
effectuate foreclosure or other

                                      -70-

conversion of the ownership of the Mortgaged Property securing any Mortgage
Loan; provided that, subject to Section 6.03, no Servicer shall take any action
that is inconsistent with or prejudices the interests of the Trust Fund or the
Certificateholders in any Mortgage Loan serviced by it under this Agreement or
the rights and interests of the other parties to this Agreement except as
otherwise required by this Agreement or by law. Each Servicer shall not make or
permit any modification, waiver or amendment of any term of any Mortgage Loan
which would cause any of the REMICs provided for herein to fail to qualify as a
REMIC or result in the imposition of any tax under Section 860G(a) or 860G(d) of
the Code. Each Servicer shall represent and protect the interest of the Trust
Fund in the same manner as each currently protects its own interest in mortgage
loans in its own portfolio in any claim, proceeding or litigation regarding a
Mortgage Loan, but in any case not 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, each Servicer, in its own name or in the name of
the Depositor and the Trustee, is hereby authorized and empowered by the
Depositor, the Securities Administrator and the Trustee, when each Servicer
believes it appropriate in its reasonable judgment, to execute and deliver, on
behalf of the Trustee, the Depositor, the Securities Administrator, the
Certificateholders or any of them, any and all instruments of satisfaction or
cancellation, or of partial or full release or discharge, subordinations 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. Each Servicer shall prepare and deliver to the Depositor,
the Securities Administrator and/or the Trustee such documents requiring
execution and delivery by either or both of them as are necessary or appropriate
to enable such Servicer to service and administer the Mortgage Loans, to the
extent that such Servicer is not permitted to execute and deliver such documents
pursuant to the preceding sentence. Upon receipt of such documents, the
Depositor, the Securities Administrator and/or the Trustee shall execute such
documents and deliver them to the related Servicer. For purposes of this Section
3.01, the Trustee hereby will provide to each Servicer 50 powers of attorney
(intended to be one power of attorney for each state in the United States) to
execute and file any and all documents necessary to fulfill the obligations of
each Servicer under this Section 3.01.

      Neither Servicer shall be required to make any Servicing Advance with
respect to a Mortgage Loan that is 150 days or more delinquent.

      Each Servicer shall deliver a list of Servicing Officers to the Securities
Administrator and the Trustee by the Closing Date (or the Subsequent Transfer
Date with respect to Subsequent Mortgage Loans).

      Each Servicer for each related Mortgage Loan has fully furnished, in
accordance with the Fair Credit Reporting Act and its implementing regulations,
accurate and complete information (i.e., favorable and unfavorable) on its
borrower credit files to Equifax, Experian, and Trans Union Credit Information
Company (three of the credit repositories), on a monthly basis.

      Each Servicer will transmit full-file credit reporting data for each
Mortgage Loan pursuant to Fannie Mae Guide Announcement 97-02 and that for each
Mortgage Loan, each Servicer agrees that it shall report one of the following
statuses each month as follows: current, delinquent (30-, 60-, 90-days, etc.),
foreclosed or charged-off.

      Each 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 related Servicer or the Subservicer, as the case
may be, believes it is appropriate in its best judgment to register any Mortgage
Loan on the MERS System, or cause the removal from the registration of any
Mortgage Loan on the MERS 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

                                      -71-

<PAGE>

successors and assigns. Any reasonable expenses incurred in connection with the
actions described in the preceding sentence or as a result of MERS discontinuing
or becoming unable to continue operations in connection with the MERS System,
shall be subject to withdrawal by the related Servicer from the Collection
Account.

      SECTION 3.02. Servicing and Subservicing; Enforcement of the Obligations
of the Servicers.

            (a)   Each Servicer may arrange for the subservicing of any Mortgage
Loan by a subservicer, which may be an affiliate (each, a "Subservicer")
pursuant to a subservicing agreement (each, a "Subservicing Agreement");
provided, however, 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) that such Subservicing Agreement would not result in a
withdrawal or downgrading by any Rating Agency of the ratings of any
Certificates evidenced by a letter to that effect delivered by each Rating
Agency to the Depositor. Notwithstanding the provisions of any Subservicing
Agreement, any of the provisions of this Agreement relating to agreements or
arrangements between the related Servicer and a Subservicer or reference to
actions taken through a Subservicer or otherwise, the related Servicer shall
remain obligated and liable to the Depositor, the Securities Administrator, 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 related
Servicer alone were servicing and administering the Mortgage Loans. Every
Subservicing Agreement entered into by each Servicer shall contain a provision
giving any successor servicer the option to terminate such agreement in the
event a successor servicer is appointed. All actions of the each Subservicer
performed pursuant to the related Subservicing Agreement shall be performed as
an agent of the related Servicer with the same force and effect as if performed
directly by such Servicer. The related Servicer shall deliver to the Securities
Administrator copies of all Subservicing Agreements. The Trustee shall have no
obligations, duties or liabilities with respect to a subservicer including no
obligation, duty or liability to monitor such subservicer or to pay a
Subservicer's fees and expenses.

            (b)   For purposes of this Agreement, each 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 each Servicer.

      SECTION 3.03. Rights of the Depositor, the Securities Administrator, the
Backup Servicer and the Trustee in Respect of either Servicer.

      None of the Securities Administrator, the Trustee, the Backup Servicer nor
the Depositor shall have any responsibility or liability for any action or
failure to act by either Servicer, and none of them is obligated to supervise
the performance of each Servicer hereunder or otherwise.

      SECTION 3.04. The Master Servicer or Backup Servicer to Act as Servicer.

      Subject to Sections 7.04 and 8.02, in the event that a Servicer shall for
any reason no longer be a Servicer hereunder (including by reason of an Event of
Default), the successor servicer (which may be the Securities Administrator, the
Master Servicer or the Backup Servicer pursuant to Section 8.02) shall, within a
period of time not to exceed ninety (90) days from the date of notice of
termination or resignation, thereupon assume all of the rights and obligations
of such Servicer hereunder arising thereafter (except that the Securities
Administrator, the Master Servicer or Backup Servicer shall not be (i) liable
for losses of such Servicer pursuant to Section 3.10 hereof or any acts or
omissions of such predecessor Servicer hereunder, (ii) obligated to make
Advances or Servicing Advance if it is prohibited

                                      -72-

<PAGE>

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 any expenses of such Servicer pursuant to
Section 2.03 or (v) deemed to have made any representations and warranties
hereunder, including pursuant to Section 2.04 or the first paragraph of Section
7.02 hereof; provided, however that the Securities Administrator, the Master
Servicer or the Backup Servicer (subject to clause (ii) above) or its designee,
in its capacity as the successor servicer, shall immediately assume the
terminated or resigning Servicer's obligation to make Advances and Servicing
Advances). No such termination shall affect any obligation of the applicable
Servicer to pay amounts owed under this Agreement and to perform its duties
under this Agreement until its successor assumes all of its rights and
obligations hereunder. If a Servicer shall for any reason no longer be a
Servicer (including by reason of any Event of Default), the Securities
Administrator, the Master Servicer or the Backup Servicer (or any other
successor servicer) may, at its option, succeed to any rights and obligations of
such Servicer under any subservicing agreement in accordance with the terms
thereof; provided, however, that the Securities Administrator, the Master
Servicer or the Backup Servicer (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 applicable
Servicer thereunder; and such Servicer shall not thereby be relieved of any
liability or obligations under the subservicing agreement arising prior to the
date of such succession. Notwithstanding anything to the contrary herein, in no
event will a successor servicer be liable for any expenses or liabilities that
were incurred by a predecessor servicer. To the extent any costs or expenses,
including without limitation Servicing Transfer Costs incurred by the Securities
Administrator, the Master Servicer or the Backup Servicer in connection with
this Section 3.04, are not paid by the applicable Servicer pursuant to this
Agreement within 30 days of the date of the Securities Administrator's, the
Master Servicer's or the Backup Servicer's invoice, as applicable, thereof, such
amounts shall be payable out of funds on deposit in the Master Servicer
Collection Account. The terminated Servicer shall reimburse the Trust Fund for
any such expense incurred by the Trust Fund upon receipt of a reasonably
detailed invoice evidencing such expenses. If the Securities Administrator, the
Master Servicer or the Backup Servicer is unwilling or unable to act as
servicer, the Master Servicer shall seek to appoint a successor servicer that is
eligible in accordance with the criteria specified this Agreement.

      The applicable Servicer shall, upon request of the Securities
Administrator, the Master Servicer or the Backup Servicer, but at the expense of
such Servicer, deliver to the assuming party all documents and records relating
to each subservicing agreement and the Mortgage Loans then being serviced and
otherwise use its best efforts to effect the orderly and efficient transfer of
the subservicing agreement to the assuming party.

      In the event that any Servicer shall for any reason no longer be able to
be a Servicer hereunder, notwithstanding anything to the contrary herein, the
Trustee and the Depositor hereby agree that within 10 Business Days of delivery
to the Trustee and the Securities Administrator by the Servicing Rights Pledgee
of a letter signed by such Servicer whereby such Servicer shall resign as
Servicer under this Agreement, the Servicing Rights Pledgee or its designee
shall be appointed as successor Servicer (provided that at the time of such
appointment the Servicing Rights Pledgee or such designee meets the requirements
of a successor Servicer set forth above) and the Servicing Rights Pledgee agrees
to be subject to the terms of this Agreement.

      SECTION 3.05. Collection of Mortgage Loan Payments; Collection Account;
Master Servicer Collection Account; Certificate Account.

            (a)   Each Servicer shall make reasonable efforts in accordance with
Accepted Servicing Practices 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

                                      -73-

<PAGE>

of any related Required Insurance Policy. Consistent with the foregoing, each
Servicer may in its discretion (i) waive any late payment charge or, if
applicable, any penalty interest, or (ii) subject to Section 3.01, extend the
due dates for payments due on a Mortgage Note for a period not greater than 180
days; provided, however, that any extension pursuant to clause (ii) above shall
not affect the amortization schedule of any Mortgage Loan for purposes of any
computation hereunder, except as provided below. In the event of any such
arrangement pursuant to clause (ii) above, subject to Section 5.01, each
Servicer shall make any 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.
Notwithstanding the foregoing, in the event that any Mortgage Loan is in default
or, in the judgment of a Servicer, such default is reasonably foreseeable, such
Servicer, subject to the provisions of Section 3.01, may also waive, modify or
vary any term of such Mortgage Loan (including modifications that would change
the Mortgage Rate, forgive the payment of principal or interest or extend the
final maturity date of such Mortgage Loan), accept payment from the related
Mortgagor of an amount less than the Stated Principal Balance in final
satisfaction of such Mortgage Loan, or consent to the postponement of strict
compliance with any such term or otherwise grant indulgence to any Mortgagor
(any and all such waivers, modifications, variances, forgiveness of principal or
interest, postponements, or indulgences collectively referred to herein as
"forbearance"), provided, however, that in determining which course of action
permitted by this sentence it shall pursue, each Servicer shall adhere to the
standards of Section 3.01. A Servicer's analysis supporting any forbearance and
the conclusion that any forbearance meets the standards of Section 3.01 shall be
reflected in writing in the Mortgage File.

            (b)   Each Servicer will not waive any Prepayment Penalty or portion
thereof unless, (i) the enforceability thereof shall have been limited by
bankruptcy, insolvency, moratorium, receivership or other similar laws relating
to creditors' rights generally or is otherwise prohibited by law, or (ii) the
collectability thereof shall have been limited due to acceleration in connection
with a foreclosure or other involuntary payment, or (iii) the applicable
Servicer has not been provided with information sufficient to enable it to
collect the Prepayment Penalty, or (iv) in the applicable Servicer's reasonable
judgment as described in Section 3.01 hereof, (x) such waiver relates to a
default or a reasonably foreseeable default, (y) such waiver would maximize
recovery of total proceeds taking into account the value of such Prepayment
Penalty and related Mortgage Loan and (z) doing so is standard and customary in
servicing similar Mortgage Loans (including any waiver of a Prepayment Penalty
in connection with a refinancing of a Mortgage Loan that is related to a default
or a reasonably foreseeable default). Except as provided in the preceding
sentence, in no event will either Servicer waive a Prepayment Penalty in
connection with a refinancing of a Mortgage Loan that is not related to a
default or a reasonably foreseeable default. If a Servicer waives or does not
collect all or a portion of a Prepayment Penalty relating to a Principal
Prepayment in full or in part due to any action or omission of such Servicer,
other than as provided above, such Servicer shall deposit the amount of such
Prepayment Penalty (or such portion thereof as had been waived for deposit) into
the Collection Account for distribution in accordance with the terms of this
Agreement. In connection with any waiver of a Prepayment Penalty by a Servicer,
such Servicer shall account for such waiver in its monthly reports as agreed
upon by such Servicer and the Credit Risk Manager.

            (c)   Each 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.

            (d)   Each Servicer shall establish and initially maintain, on
behalf of the Certificateholders, one or more Collection Accounts, in the form
of time deposit or demand accounts, titled "[Servicer's Name], as servicer for
U.S. Bank National Association, as trustee, in trust for the

                                      -74-

<PAGE>

Holders of Terwin Mortgage Trust 2004-3HE, Asset-Backed Certificates, TMTS
Series 2004-3HE". Each Servicer shall deposit into the Collection Account daily,
within two Business Days of receipt thereof, in immediately available funds, the
following payments and collections received or made by it on and after the
Cut-Off Date with respect to the Mortgage Loans (or Subsequent Cut-off Date with
respect to Subsequent Mortgage Loans):

                  (i)   all payments on account of principal, including
Principal Prepayments, on the Mortgage Loans, other than principal due on the
Mortgage Loans on or prior to the Cut-off Date or Subsequent Cut-off Date, as
applicable;

                  (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 due on the Mortgage Loans on or prior to the Cut-off Date or Subsequent
Cut-off Date, as applicable;

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

                  (iv)  all Subsequent Recoveries;

                  (v)   all Compensating Interest;

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

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

                  (viii) all Advances made by each Servicer pursuant to Section
5.01;

                  (ix)  all Prepayment Penalties; and

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

      The foregoing requirements for remittance by a Servicer into the
Collection Account shall be exclusive, it being understood and agreed that,
without limiting the generality of the foregoing, late payment charges,
insufficient funds charges and payments in the nature of assumption fees (i.e.
fees related to the assumption of a Mortgage Loan upon the purchase of the
related Mortgaged Property and other similar ancillary fees (other than
Prepayment Penalties) if collected, need not be remitted by such Servicer. In
the event that a 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 Securities Administrator, or such other
institution maintaining the Collection Account, to withdraw such amount from the
Collection Account, any provision herein to the contrary notwithstanding. Each
Servicer shall maintain adequate records with respect to all withdrawals made
pursuant to this Section. All funds deposited in the Collection Account shall be
held in trust for the Certificateholders until withdrawn in accordance with
Section 3.08. In no event shall the Securities Administrator or the Trustee
incur liability for withdrawals from the Collection Account at the direction of
each Servicer.

      Each Servicer shall give notice to the Securities Administrator, the
Master Servicer, the Backup Servicer and the Trustee of the location of the
Collection Account maintained by it when established and prior to any change
thereof. Not later than twenty days after each Distribution Date, each Servicer
shall forward to the Securities Administrator, the Trustee and the Depositor the
most current available bank

                                      -75-

<PAGE>

statement for the Collection Account. Copies of such statement shall be provided
by the Securities Administrator to any Certificateholder and to any Person
identified to the Securities Administrator as a prospective transferee of a
Certificate, upon request at the expense of the requesting party, provided such
statement is delivered by each Servicer to the Securities Administrator.

            (e)   The Master Servicer shall establish and maintain an account,
for the benefit of the Certificateholders, as a segregated account (the "Master
Servicer Collection Account"), which shall be an Eligible Account. The Master
Servicer shall, promptly upon receipt from the related Servicer on the Servicer
Remittance Date, deposit into the Master Servicer Collection Account and retain
on deposit until the related Master Servicer Remittance Date, the following
amounts:

                  (i)   the aggregate amount remitted by such Servicer to the
Master Servicer pursuant to Section 3.08(a)(viii) and any amounts remitted by
the Interim Servicer pursuant to the Interim Servicing Agreement; and

                  (ii)  any other amounts deposited hereunder which are required
to be deposited in the Master Servicer Collection Account pursuant to this
Agreement including, but not limited to, any amounts due to the Trustee, the
Securities Administrator or the Backup Servicer pursuant to Section 3.08 and
Article IX herein.

      In the event that the related Servicer shall remit to the Master Servicer
any amount not required to be remitted, such Servicer may at any time in writing
direct the Master Servicer to withdraw such amount from the Master Servicer
Collection Account, any provision herein to the contrary notwithstanding. Such
direction may be accomplished by delivering written notice to the Master
Servicer (upon which the Master Servicer may conclusively rely) which describes
the amounts deposited in error in the Master Servicer Collection Account. All
funds deposited in the Master Servicer Collection Account shall be held by the
Master Servicer in trust for the Certificateholders until disbursed in
accordance with this Agreement or withdrawn in accordance with Section 3.08(b).
In no event shall the Master Servicer incur liability for withdrawals from the
Master Servicer Collection Account at the direction of the related Servicer. The
Master Servicer shall give notice to the Securities Administrator, the Master
Servicer, the Backup Servicer and each Servicer of the location of the Master
Servicer Collection Account maintained by it when established and prior to any
change thereof.

            (f)   The Securities Administrator shall establish and maintain, on
behalf of the Certificateholders, the Certificate Account. The Securities
Administrator shall, promptly upon receipt from the Master Servicer on the
Master Servicer Remittance Date, deposit or cause to be deposited in the
Certificate Account and retain therein the following:

                  (i)   The aggregate amount remitted by the Master Servicer to
the Securities Administrator pursuant to Section 3.05(e); and;

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

                  (iii) any amount required to be deposited by the Securities
Administrator pursuant to Section 3.05(g) in connection with any losses on
Permitted Investments; and

                  (iv)  the Optional Termination Amount paid by Countrywide
pursuant to Section 10.01.

      Any amounts received by the Securities Administrator prior to 1:00 p.m.
New York City time (or such earlier deadline for investment in the Permitted
Investments designated by the Securities Administrator) which are required to be
deposited in the Certificate Account by each Servicer or Master

                                      -76-

<PAGE>

Servicer shall be invested in Permitted Investments on the Business Day on which
they were received. The foregoing requirements for remittance by each Servicer
and Master Servicer and deposit by each Servicer and Master Servicer into the
Certificate Account shall be exclusive. In the event that the Master Servicer
shall remit to the Securities Administrator any amount not required to be
remitted, it may at any time in writing direct the Securities Administrator to
withdraw such amount from the Certificate Account, any provision herein to the
contrary notwithstanding. Such direction may be accomplished by delivering
written notice to the Securities Administrator (upon which the Securities
Administrator may conclusively rely) which describes the amounts deposited in
error in the Certificate Account. All funds deposited in the Certificate Account
shall be held by the Securities Administrator 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 Securities
Administrator incur liability for withdrawals from the Certificate Account at
the direction of the Master Servicer. The Securities Administrator shall give
notice to the Trustee, the Master Servicer and each Servicer of the location of
the Certificate Account maintained by it when established and prior to any
change thereof.

            (g)   Each institution that maintains a Collection Account or the
Master Servicer Collection Account shall invest the funds in each such account,
as directed by a Servicer, the Master Servicer, as applicable, in writing, in
Permitted Investments, which shall mature not later than (i) in the case of the
Collection Account the Business Day preceding the related Servicer Remittance
Date (except that if such Permitted Investment is an obligation of the
institution that maintains such Collection Account or is otherwise immediately
available, then such Permitted Investment shall mature not later than each
Servicer Remittance Date) and (ii) in the case of the Master Servicer Collection
Account, the Business Day preceding the related Master Servicer Remittance Date
(except that if such Permitted Investment is an obligation of the institution
that maintains such Master Servicer Collection Account or is otherwise
immediately available, then such Permitted Investment shall mature not later
than each Master Servicer Remittance Date) and, 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 a Servicer or the Master Servicer, as applicable, for the
benefit of the Certificateholders. All income and gain net of any losses
realized from amounts on deposit in the Collection Account shall be for the
benefit of the related Servicer as servicing compensation and shall be remitted
to it monthly as provided herein. The amount of any losses incurred in the
Collection Account in respect of any such investments shall be deposited by the
related Servicer in the Collection Account out of such Servicer's own funds
immediately as realized. All income and gain net of any losses realized from
amounts on deposit in the Master Servicer Collection Account shall be for the
benefit of the Master Servicer as master servicing compensation and shall be
remitted to it monthly as provided herein. The amount of any losses incurred in
the Master Servicer Collection Account in respect of any such investments shall
be deposited by the Master Servicer in the Master Servicer Collection Account
out of such Master Servicer's own funds immediately as realized. The Securities
Administrator shall retain the funds in the Certificate Account uninvested.

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

      To the extent required by the related Mortgage Note, each 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
each Servicer) for the payment of taxes, assessments, hazard insurance premiums
or comparable items for the account of the Mortgagors. Nothing herein shall
require each 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 each
Servicer out of related collections for any payments made pursuant to Sections

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

of this Agreement in accordance with Section 9.01 hereof. The Escrow Accounts

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

      Upon reasonable advance notice in writing if required by federal
regulation, each Servicer will provide to each Certificateholder 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 to comply with applicable
regulations of the OTS or other regulatory authorities with respect to
investment in the Certificates; provided, that each Servicer shall be entitled
to be reimbursed by each such Certificateholder for actual expenses incurred by
each Servicer in providing such reports and access.

                  (i)   to pay to such Servicer (to the extent not previously
paid to or withheld by each 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, those other amounts set forth
in Section 3.15;

                  (ii)  to reimburse such Servicer for Advances made by it (or

Loan(s) in respect of which any such Advance was made;

                  (iii) to reimburse such Servicer for any Non-Recoverable
Advance previously made and any Non-Recoverable Servicing Advances previously
made to the extent that, in the case of Non-Recoverable Servicing Advances,
reimbursement therefor constitutes "unanticipated expenses" within the meaning
of Treasury Regulation Section 1.860G-1(b)(3)(ii);

                  (iv)  to pay to such Servicer earnings on or investment income

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;

                  (viii) to pay to the Depositor or such 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 or 3.12, all
amounts received thereon and not taken into account in determining the related
Stated Principal Balance of such repurchased Mortgage Loan;

                  (ix)  to reimburse such Servicer, the Master Servicer, the
Securities Administrator, the Trustee or the Depositor for expenses incurred by
any of them in connection with the Mortgage Loans or Certificates and
reimbursable pursuant to Section 3.25 or Section 6.03 hereof provided that
reimbursement therefor would constitute "unanticipated" expenses within the
meaning of Treasury Regulation Section 1.860G-1(b)(3)(ii);

                  (x)   to reimburse the Securities Administrator for
enforcement expenses reasonably incurred in respect of a breach of defect giving
rise to the purchase obligation in Section 2.03 that were incurred in the
Purchase Price of the Mortgage Loans including any expenses arising out of the
enforcement of the purchase obligation; provided that any such expenses will be
reimbursable under this subclause (x) only to the that such expenses would
constitute "unanticipated expenses" within the meaning of Treasury Regulation
Section 1.860G-1(b)(3)(ii) if paid by one of the REMICs provided for herein;

                  (xi)  to pay the Trustee and/or Securities Administrator any
amounts owed to them pursuant to Article IX.

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

                  (xiii) to clear and terminate the Collection Account upon
termination of this Agreement pursuant to Section 10.01 hereof.

      In addition, no later than 1:00 p.m. Eastern Time on each Servicer
Remittance Date, each Servicer shall cause to be withdrawn from the Collection
Account the Interest Funds, the Principal Funds and the Administration Fee
(other than the related Servicing Fee and any fees charged by the Interim
Servicer) (collectively, the "Servicer Withdrawals"), to the extent on deposit,
and such amount shall be deposited in the Master Servicer Collection Account;
provided, however, if the Master Servicer does not receive such Servicer
Withdrawals by 4:00 p.m. Eastern Time, such Servicer Withdrawals shall be
deposited by the Master Servicer in the Master Servicer Collection Account by
1:00 p.m. Eastern Time on the next Business Day. In the event such Servicer
Withdrawals are not deposited by 1:00 p.m. Eastern Time, each Servicer shall
pay, out of its own funds, interest on such amount at a rate equal to the Master
Servicer's Prime Rate for each date or part thereof.

      Each Servicer shall keep and maintain separate accounting, on a Mortgage
Loan by Mortgage Loan basis, for the purpose of justifying any withdrawal from
the Collection Account.

      Each Servicer shall provide written notification to the Trustee, the
Master Servicer and the Securities Administrator on or prior to the next
succeeding Servicer Remittance Date upon making any withdrawals from the
Collection Account pursuant to subclauses (iii) and (vii) above.

      Unless otherwise specified, any amounts reimbursable to each Servicer or
the Securities Administrator from amounts on deposit in the Collection Account,
the Master Servicer Collection

                                      -79-

<PAGE>

Account or the Certificate Accounts shall be deemed to come from first, Interest
Funds, and thereafter, Principal Funds for the related Distribution Date.

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

                  (i)   to withdraw any amounts deposited in such Master
Servicer Collection Account and not required to be deposited therein;

                  (ii)  to clear and terminate the Master Servicer Collection
Account upon termination of this Agreement pursuant to Section 10.01 hereof;

                  (iii) (a) to pay itself the Master Servicing Fee with respect

Administrator does not receive such Master Servicer Withdrawals by 4:00 p.m.
Eastern Time, such Master Servicer Withdrawals shall be deposited by the

own funds, interest on such amount at a rate equal to the Federal Funds Rate for
each date or part thereof.

      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 Master Servicer Collection Account.

      Unless otherwise specified, any amounts reimbursable to a Servicer, the
Master Servicer or the Trustee from amounts on deposit in the Collection
Account, the Master Servicer Collection Account or the Certificate Accounts

Funds for the related Distribution Date.

            (c)   The Securities Administrator shall withdraw funds from the
Certificate Account for distribution to the Certificateholders in the manner
specified in this Agreement in Section 5.05 (and to withhold from the amounts so

deposited in the Certificate Account and not required to be deposited therein;

                                      -80-

<PAGE>

                  (iii) to clear and terminate the Certificate Account upon
termination of the Agreement pursuant to Section 10.01 hereof;

                  (iv)  to pay the Credit Risk Manager the Credit Risk Manager
Fee;

                  (v)   to pay the Backup Servicer the Backup Servicing Fee with

any such Person in accordance with the provisions of this Agreement, including,
without limitation, any Advances made by the Master Servicer and/or the Backup
Servicer, each in its individual capacity as successor servicer.

      SECTION 3.09. Servicing Transfer Date.

            (a)   The Interim Servicer will service all Mortgage Loans serviced
by it pursuant to the terms of the Interim Servicing Agreement during the
Interim Servicing Period. Neither Servicer shall be obligated to perform any
duties or responsibilities under this Agreement with respect to a related
Mortgage Loan until the servicing rights to such Mortgage Loan have been
transferred to such Servicer on the Servicing Transfer Date. On the Servicing
Transfer Date, the related Servicer agrees to accept the servicing of the
Mortgage Loans previously serviced by the Interim Servicer. Each Servicer agrees
to cooperate with the Interim Servicer to effectuate the timely transfer of
servicing from the Interim Servicer to such Servicer on the related Servicing
Transfer Date. Neither Servicer shall be liable for any actions or inactions of
any prior servicer of a Mortgage Loan prior to the Servicing Transfer Date nor
shall any action or inaction by a prior servicer be deemed an Event of Default
with respect to such Servicer. Each Servicer shall confirm that the Mortgage
Loans on the Mortgage Loan Schedule have been transferred for servicing to such
Servicer and shall notify the Depositor, the Master Servicer, the Securities
Administrator and the Trustee promptly following the completion of such transfer
on the Servicing Transfer Date.

      SECTION 3.10. [RESERVED].

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

      When a Mortgaged Property has been or is about to be conveyed by the
Mortgagor, the related Servicer shall, except as set forth below, to the extent
it has knowledge of such conveyance or prospective conveyance, exercise its
rights to accelerate the maturity of the related Mortgage Loan under any
"due-on-sale" clause contained in the related Mortgage or Mortgage Note;
provided, however, that such Servicer shall not exercise any such right if the
"due-on-sale" clause, in the reasonable belief of such Servicer, is not
enforceable under applicable law; provided, further, that such Servicer shall
not take any action in relation to the enforcement of any "due-on-sale" clause
which would adversely affect or jeopardize coverage under any Required Insurance
Policy. An Opinion of Counsel at the expense of the related Servicer (which the
expense shall constitute a Servicing Advance) delivered to the Securities
Administrator, the Trustee and the Depositor shall conclusively establish the
reasonableness of such Servicer's belief that any "due-on-sale" clause is not
enforceable under applicable law. In such event, a Servicer shall make
reasonable efforts to enter into an assumption and modification agreement 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 law or the Mortgage, the Mortgagor remains liable
thereon. If the foregoing is not permitted under applicable law, the related
Servicer is authorized 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 Note.
In addition to the foregoing, a Servicer shall not be required to enforce

                                      -81-

<PAGE>

any "due-on-sale" clause if in the reasonable judgment of such Servicer,
entering into an assumption and modification agreement with a Person to whom
such property shall be conveyed and releasing the original Mortgagor from
liability would be in the best interests of the Certificateholders. The Mortgage
Loan, as assumed, shall conform in all respects to the requirements,
representations and warranties of this Agreement. A Servicer shall notify the
Securities Administrator that any such assumption or substitution agreement has
been completed by forwarding to the Securities Administrator the original copy
of such assumption or substitution agreement (indicating the Mortgage File to
which it relates) which copy shall be added by the Securities Administrator to
the related Mortgage File and which 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. Each Servicer shall be responsible for
recording any such assumption or substitution agreements. In connection with any
such assumption or substitution agreement, the Monthly Payment on the related
Mortgage Loan shall not be changed but shall remain as in effect immediately
prior to the assumption or substitution, the stated maturity or outstanding
principal amount of such Mortgage Loan shall not be changed nor shall any
required monthly payments of principal or interest be deferred or forgiven. Any
fee collected by a Servicer for consenting to any such conveyance or entering
into an assumption or substitution agreement shall be retained by or paid to
such Servicer as additional servicing compensation.

      Notwithstanding the foregoing paragraph or any other provision of this
Agreement, no Servicer shall be deemed to be in default, breach or any other
violation of its obligations hereunder by reason of any assumption of a Mortgage
Loan by operation of law or any assumption which the related Servicer may be
restricted by law from preventing, for any reason whatsoever.

      SECTION 3.12. Realization Upon Defaulted Mortgage Loans; Determination of
Excess Proceeds.

            (a)   Each Servicer shall use reasonable efforts consistent with the
Acceptable Servicing Practices 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, a 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, however, that such Servicer shall not be
required to expend its own funds in connection with the restoration of any
property that shall have suffered damage due to an uninsured cause unless it
shall determine (i) that such restoration 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
Collection Account pursuant to Section 3.08 hereof). The related Servicer shall
be responsible for all other costs and expenses incurred by it in any such
proceedings; provided, however, that it shall be entitled to reimbursement
thereof from the proceeds of liquidation of the related Mortgaged Property, as
contemplated in Section 3.08 hereof. If a Servicer has knowledge that a
Mortgaged Property that such 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 such Servicer, each
Servicer will, prior to acquiring the Mortgaged Property, consider such risks
and only take action in accordance with Accepted Servicing Practices.

      With respect to any REO Property, the deed or certificate of sale shall be
taken in the name of the Trustee or its nominee. Pursuant to its efforts to sell
such REO Property, the related Servicer shall either itself or through an agent
selected by such 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

                                      -82-

<PAGE>

part thereof, as such Servicer deems to be in the best interest of such Servicer
and the Certificateholders for the period prior to the sale of such REO
Property. A Servicer or an affiliate may receive usual and customary real estate
referral fees for real estate brokers in connection with the listing and
disposition of REO Property. The related Servicer shall prepare 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 such
Servicer 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 Collection Account no later than the close of business on each Determination
Date. Each 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 related Servicer shall dispose of such Mortgaged Property
prior to the expiration of three years from the end of the year of its
acquisition by the Trust Fund or, at the expense of the Trust Fund, request, in
accordance with applicable procedures for obtaining an automatic extension of
the grace period, 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
which case such property must be disposed of prior to the end of such extension,
unless the Trustee and Securities Administrator shall have been supplied with an
Opinion of Counsel (such Opinion of Counsel not to be an expense of the Trustee
or the Securities Administrator), to the effect that the holding by the Trust
Fund of such Mortgaged Property subsequent to such three-year period or
extension will not result in the imposition of taxes on "prohibited
transactions" of the Trust Fund or any of the REMICs provided for herein as
defined in section 860F of the Code or cause any of the REMICs provided for
herein to fail to qualify as a REMIC at any time that any Certificates are
outstanding, in which case the Trust Fund may continue to hold such Mortgaged
Property (subject to any conditions contained in such Opinion of Counsel).
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 or any REMIC
provided for herein to the imposition of any federal, state or local income
taxes on the income earned from such Mortgaged under section 860G(c) of the Code
or otherwise, unless the related Servicer or the Depositor has agreed to
indemnify and hold harmless the Trust Fund with respect to the imposition of any
such taxes.

      The decision of a Servicer to foreclose on a defaulted Mortgage Loan shall
be subject to a determination by such 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 such
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 Collection 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.

                                      -83-

<PAGE>

      The Liquidation Proceeds from any liquidation of a Mortgage Loan, net of
any payment to the related Servicer as provided above, shall be deposited in the
Collection Account on the next succeeding Determination Date following receipt
thereof for distribution on the related Distribution Date.

      The proceeds of any Liquidated 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 related 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 such Servicer for any unreimbursed Advances, pursuant to
Section 3.08(a)(ii) or this Section 3.12; third, to any prepayment penalties and
then 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.

            (b)   On each Determination Date, each Servicer shall determine the
respective aggregate amounts of Excess Proceeds, if any, that occurred in the
related Prepayment Period.

            (c)   Each Servicer, in its sole discretion, shall have the right to
elect (by written notice sent to the Trustee, the Securities Administrator and
the Seller) to purchase for its own account from the Trust Fund any Mortgage
Loan that is 90 days or more Delinquent at a price equal to the Purchase Price.
The Purchase Price for any Mortgage Loan purchased hereunder shall be delivered
to the Securities Administrator for deposit to the Certificate Account and the
Securities Administrator, upon receipt of such confirmation of deposit and a
Request for Release from the related Servicer in the form of Exhibit I hereto,
shall release or cause to be released to the related Servicer the related
Mortgage File and shall execute and deliver such instruments of transfer or
assignment prepared by each Servicer, in each case without recourse, as shall be
necessary to vest in such Servicer any Mortgage Loan released pursuant hereto
and such Servicer 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. Such
Servicer shall thereupon own such Mortgage Loan, and all security and documents,
free of any further obligation to the Securities Administrator 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 a
Servicer of a notification that payment in full will be escrowed in a manner
customary for such purposes, such Servicer will promptly notify the Custodian by
delivering a Request for Release substantially in the form of Exhibit I. Upon
receipt of a copy of such request, the Custodian shall promptly release the
related Mortgage File to the related Servicer, and such Servicer is authorized
to cause the removal from the registration on the MERS System of any such
Mortgage if applicable, and the Trustee shall at the related Servicer's written
direction execute and deliver to the such 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 such Servicer,
together with the Mortgage Note with written evidence of cancellation thereon.
Expenses incurred in connection with any instrument of satisfaction or deed of
reconveyance shall be chargeable to the Mortgagor to the extent permitted by
law, and otherwise to the Trust Fund to the extent such expenses constitute
"unanticipated expenses" within the meaning of Treasury Regulations Section
1.860G-(1)(b)(3)(ii). 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 Custodian, upon delivery to

                                      -84-

<PAGE>

the Custodian of a Request for Release in the form of Exhibit I signed by a
Servicing Officer, release the Mortgage File to the related Servicer. Subject to
the further limitations set forth below, the related Servicer shall cause the
Mortgage File or documents so released to be returned to the Custodian when the
need therefor by such Servicer no longer exists, unless the Mortgage Loan is
liquidated and the proceeds thereof are deposited in the Collection Account.

      Each Request for Release may be delivered to the Custodian (i) via mail or
courier, (ii) via facsimile or (iii) by such other means, including, without
limitation, electronic or computer readable medium, as the related Servicer and
the Custodian shall mutually agree. The Custodian shall promptly release the
related Mortgage File(s) within five (5) Business Days of receipt of a properly
completed Request for Release pursuant to clauses (i), (ii) or (iii) above.
Receipt of a properly completed Request for Release shall be authorization to
the Custodian to release such Mortgage Files, provided the Custodian has
determined that such Request for Release has been executed, with respect to
clauses (i) or (ii) above, or approved, with respect to clause (iii) above, by
an authorized Servicing Officer of the related Servicer, and so long as the
Custodian complies with its duties and obligations under the agreement. If the
Trustee or its designee is unable to release the Mortgage Files within the
period previously specified, the Custodian shall immediately notify the related
Servicer indicating the reason for such delay. If the related Servicer is
required to pay penalties or damages due to the Custodian's negligent failure to
release the related Mortgage File or the Custodian's negligent failure to
execute and release documents in a timely manner, the Custodian, shall be liable
for such penalties or damages respectively caused by it.

      Notwithstanding the foregoing, in connection with a Principal Prepayment
in full of any Mortgage Loan, the Master Servicer or the Backup Servicer may
request release of the related Mortgage File from the Custodian, in accordance
with the provisions of this Agreement, in the event the related Servicer fails
to do so. If requested by the Master Servicer, the Backup Servicer or a
Servicer, the Custodian shall forward such Mortgage File or other requested
items to the requesting party by overnight mail at the requesting party's
expense.

      If a Servicer at any time seeks to initiate a foreclosure proceeding in
respect of any Mortgaged Property as authorized by this Agreement, such 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, a Servicer shall cause possession of any Mortgage
File or of the documents therein that shall have been released by the Custodian
to be returned to the Custodian promptly after possession thereof shall have
been released by the Custodian unless (i) the Mortgage Loan has been liquidated
and the Liquidation Proceeds relating to the Mortgage Loan have been deposited
in the Collection Account, and the related Servicer shall have delivered to the
Custodian a Request for Release in the form of Exhibit I 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

any funds on deposit in the Collection Account, shall be held by such 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. Each Servicer also agrees that it shall not create, incur or
subject any Mortgage File or any funds that are deposited in the Collection
Account or in any Escrow Account, or any funds that otherwise are or may become
due or payable to the Trustee, or the Securities Administrator as its designee,
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 each Servicer shall be entitled to set off against and deduct from

Loan upon the purchase of the related Mortgaged Property) and similar fees
payable by the Mortgagor, and all income and gain net of any losses realized
from Permitted Investments in the Collection Account shall be retained by the

required to pay all expenses incurred by it in connection with its servicing
activities hereunder and shall not be entitled to reimbursement therefor except
as specifically provided in Sections 3.08 and 3.12 hereof. The Servicers shall

business hours at the offices of related Servicer designated by it provided,
that each Servicer shall be entitled to be reimbursed by each such
Certificateholder for actual expenses incurred by the related Servicer in

obligation of each Servicer to observe any applicable law prohibiting disclosure
of information regarding the Mortgagors and the failure of the related Servicer
to provide access as provided in this Section as a result of such obligation
shall not constitute a breach of this Section.

provisions of this Agreement or, if there has been a material default in the
fulfillment of any such obligation, specifying each such material default known

SLS to cure such material default. The conclusions of the auditor shall be based
on a statistical sample of the SLS Serviced Mortgage Loans and a review of SLS's
collection, default management, escrow administration, cash management,
insurance administration and quality control procedures. In the event that such
firm requires the Securities Administrator to agree to the procedures performed

expressly set forth herein, a Servicer shall have full authority on behalf of
the Trust Fund to do anything it reasonably deems appropriate or desirable in
connection with the servicing, maintenance and administration of the LPMI
Policy. Such Servicer shall not modify or assume a Mortgage Loan covered by the
LPMI Policy or take any other action with respect to such Mortgage Loan which

the actions of such Servicer, would have been covered thereunder. If the LPMI
insurer fails to pay a claim under the LPMI Policy as a result of breach by such
Servicer of its obligations hereunder or under the LPMI Policy, such Servicer
shall be required to deposit in the related Collection Account on or prior to
the next succeeding Remittance Date an amount equal to such unpaid claim from
its own funds without any right to reimbursement from the Trust Fund. A Servicer
shall cooperate with the LPMI insurer and shall use its best efforts to furnish

to which such Servicer has access with respect to any LPMI Loan.

      SECTION 3.30. SLS Servicing Tape; Storage and Access to Servicing Tape.

Master Servicer and the Backup Servicer. SLS or its designee shall (i) maintain
the Servicing Tape at an off-site location, (ii) provide ready access to the
Servicing Tape to both the Master Servicer and the Backup Servicer; provided,

Trustee shall have no responsibility for any action of the Master Servicer
pursuant to any such limited power of attorney and shall be indemnified by the

provided, however, that, unless otherwise required by law, neither the Trustee
or the Custodian shall be required to provide access to such records and
documentation to the Certificateholders. The Trustee and the Custodian shall

documentation and shall provide equipment for that purpose at a charge that
covers the Trustee's or the Custodian's actual costs.

stating that such contribution will not result in the imposition of a tax upon
any REMIC (including but not limited to the tax on prohibited transactions as
defined in Code Section 860F(a)(2) and the tax on prohibited contributions set

      SECTION 4.04. Powers to Act; Procedures.

      The Master Servicer shall master service the Mortgage Loans and shall have
full power and authority, subject to the REMIC Provisions and the provisions of
Section 9.13, to do any and all things that it may deem necessary or desirable
in connection with the master servicing and administration of the Mortgage
Loans, including but not limited to the power and authority (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, (iii) to collect any Insurance Proceeds and Liquidation Proceeds, and
(iv) to effectuate foreclosure or other conversion of the ownership of the
Mortgaged Property securing any Mortgage Loan, in each case, in accordance with
the provisions of this Agreement; provided, however, that the Master Servicer
shall not (and, consistent with its responsibilities under Section 4.03, shall
not permit any Servicer to) knowingly or intentionally take any action, or fail
to take (or fail to cause to be taken) any action reasonably within its control
and the scope of duties more specifically set forth herein, that, under the
REMIC Provisions, if taken or not taken, as the case may be, would cause any
REMIC formed hereby to fail to qualify as a REMIC or result in the imposition of
a tax upon the Trust Fund or any REMIC provided for herein (including but not
limited to the tax on prohibited transactions as defined in Section 860F(a)(2)
of the Code and the tax on contributions to a REMIC set forth in Section 860G(d)
of the Code) unless the Master Servicer has received an Opinion of Counsel (but
not at the expense of the Master Servicer) to the effect that the contemplated
action will not cause any REMIC formed hereby to fail to qualify as a REMIC or
result in the imposition of a tax upon any REMIC formed hereby or the Trust
Fund. The Trustee shall furnish the Master Servicer, upon written request from a
Servicing Officer, with any powers of attorney empowering the Master Servicer or
the Servicers to execute and deliver instruments of satisfaction or
cancellation, or of partial or full release or discharge, and to foreclose upon
or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in
any court action relating to the Mortgage Loans or the Mortgaged Property, in
accordance with this Agreement, and the Trustee shall execute and deliver such
other documents, as the Master Servicer or any Servicer may request, to enable
the Master Servicer to master service and administer the Mortgage Loans and
carry out its duties hereunder, in each case in accordance with Accepted Master
Servicing Practices (and the Trustee shall have no liability for misuse of any
such powers of attorney by the Master Servicer or the Servicers and shall be
indemnified by the Master Servicer or the Servicers, as applicable, for any
cost, liability or expense incurred by the Trustee in connection with such
Person's use or misuse of any such power of attorney). If the Master Servicer or
the Trustee has been advised that it is likely that the laws of the state in
which action is to be taken prohibit such action if taken in the name of the
Trustee or that the Trustee would be adversely affected under the "doing
business" or tax laws of such state if such action is taken in its name, the
Master Servicer shall join with the Trustee in the appointment of a co-trustee
pursuant to Section 9.12. In the performance of its duties hereunder, the Master
Servicer shall be an independent contractor and shall not, except in those
instances where it is taking action in the name of the Trustee, be deemed to be
the agent of the Trustee.

      SECTION 4.05. Due-on-Sale Clauses; Assumption Agreements.

      To the extent Mortgage Loans contain enforceable due-on-sale clauses, the
Master Servicer shall cause the Servicers to enforce such clauses in accordance
with this Agreement. If applicable law prohibits the enforcement of a
due-on-sale clause or such clause is otherwise not enforced in accordance with
this Agreement, and, as a consequence, a Mortgage Loan is assumed, the original
Mortgagor may be released from liability in accordance with this Agreement.

the costs of such enforcement at its own expense, provided that the Master
Servicer shall not be required to prosecute or defend any legal action except to

compliance by the Interim Servicer with their duties under the Interim Servicing
Agreement. In the review of an Interim Servicer's activities, the Master
Servicer may rely upon an Officer's Certificate of the Interim Servicer with
regard to the Interim Servicer's compliance with the terms of the Interim
Servicing Agreement. In the event that the Master Servicer, in its judgment,
determines that the Interim Servicer should be terminated in accordance with the
terms of the Interim Servicing Agreement, or that a notice should be sent
pursuant to the terms thereof with respect to the occurrence of an event that,
unless cured, would constitute an event of default, the Master Servicer shall

that the Interim Servicer fails to perform its obligations in accordance with
the Interim Servicing Agreement, subject to the preceding paragraph and Article
VIII, cause the Securities Administrator to terminate the rights and obligations
of the Interim Servicer. Such enforcement, including, without limitation, the
legal prosecution of claims and the pursuit of other appropriate remedies, shall
be in such form and carried out to such an extent and at such time as the Master
Servicer, in its good faith business judgment, would require were it the owner
of the related Mortgage Loans. The Master Servicer shall pay the costs of such

                                  DISTRIBUTIONS

      SECTION 5.01. Advances by the Master Servicer and the Servicers.

      Each Servicer shall deposit in the related Collection Account at the time
described below an amount equal to, with respect to the Mortgage Loans, all
Scheduled Payments of principal and interest at the Mortgage Rate less the
Servicing Fee which were due on the related Mortgage Loans during the applicable

the purchase or repurchase thereof (or substitution therefor) from the Trust
Fund pursuant to the terms of this Agreement. No Servicer shall be required to
advance shortfalls of principal or interest resulting from any related
bankruptcy proceedings or the application of the Relief Act.

      Each Servicer shall be obligated to make Advances with respect to those
Mortgage Loans serviced by it in accordance with the provisions of this
Agreement; provided however, that such obligation with respect to any related
Mortgage Loan shall cease if the Master Servicer or a Servicer determines, in
its sole discretion, that Advances with respect to such Mortgage Loan are
Nonrecoverable Advances. In the event that the Master Servicer or a Servicer
determines that any such Advances are Nonrecoverable Advances, the Master
Servicer or such Servicer shall provide the Master Servicer with a certificate
signed by a Servicing Officer evidencing such determination.

      By 2:00 p.m. New York time on the Servicer Remittance Date, each Servicer
shall remit in immediately available funds to the Master Servicer for deposit in
the Master Servicer Collection Account an amount equal to the aggregate amount
of Advances, if any, to be made in respect of the Mortgage Loans for the related
Distribution Date either (i) from its own funds or (ii) from the Collection
Account, to the extent of any Amounts For Future Distribution on deposit therein
(in which case it will cause to be made an appropriate entry in the records of
the Collection Account that Amounts For Future Distribution have been, as
permitted by this Section 5.01, used by such Servicer in discharge of any such
Advance) or (iii) in the form of any combination of (i) and (ii) aggregating the
total amount of Advances to be made by such Servicer with respect to the
Mortgage Loans. In addition, a Servicer shall have the right to reimburse itself
for any such Advance made by it from its own funds from Amounts For Future
Distribution. In addition, a Servicer shall have the right to reimburse itself
for any outstanding Advance made by it from its own funds from amounts held from
time to time in the Collection Account to the extent such amounts are not then
required to be distributed. Any funds so applied and transferred pursuant to the
previous two sentences shall be replaced by such Servicer by deposit in the
Collection Account no later than the close

required to be distributed pursuant to this Agreement.

      SECTION 5.02. Advance Facility.

            (a)   Each Servicer is hereby authorized to enter into a financing
or other facility (any such arrangement, an "Advance Facility"), the
documentation for which complies with Section 5.02(e) below, under which (1) the
related Servicer assigns or pledges its rights under this Agreement to be
reimbursed for any or all Advances and/or Servicing Advances to (i) a Person,
which may be a special-purpose bankruptcy-remote entity (an "SPV"), (ii) a
Person, which may simultaneously assign or pledge such rights to an SPV or (iii)
a lender (a "Lender"), which, in the case of any Person or SPV of the type
described in either of the preceding clauses (i) or (ii), may directly or
through other assignees and/or pledgees, assign or pledge such rights to a
Person, which may include a trustee acting on behalf of holders of debt
instruments (any such Person or any such Lender, an "Advance Financing Person"),
and/or (2) an Advance Financing Person agrees to fund all of the Advances and/or
Servicing Advances required to be made by such Servicer pursuant to this
Agreement. No consent of the Trustee, the Securities Administrator,
Certificateholders or any other party shall be required before a Servicer may
enter into an Advance Facility, nor shall the Trustee, the Securities
Administrator or the Certificateholders be a third party beneficiary of any
obligation of an Advance Financing Person to such Servicer. Notwithstanding the
existence of any Advance Facility under which an Advance Financing Person agrees
to fund Advances and/or Servicing Advances, (A) the related Servicer (i) shall
remain obligated pursuant to this Agreement to make Advances and/or Servicing
Advances pursuant to and as required by this Agreement and (ii) shall not be
relieved of such obligations by virtue of such Advance Facility and (B) neither
the Advance Financing Person nor any Servicer's Assignee (as hereinafter
defined) shall have any right to proceed against or otherwise contact any
Mortgagor for the purpose of collecting any payment that may be due with respect
to any related Mortgage Loan or enforcing any covenant of such Mortgagor under
the related Mortgage Loan documents.

            (b)   If a Servicer enters into an Advance Facility, such Servicer
and the related Advance Financing Person shall deliver to the Trustee at the
address set forth in Section 5.02 hereof a written notice (an "Advance Facility
Notice"), stating (a) the identity of the Advance Financing Person, (b) the
identity of the Person (the "Servicer's Assignee") that will, subject to Section
3.22(c) hereof, have the right to make withdrawals from the Collection Account
pursuant to Section 3.08 hereof to reimburse previously unreimbursed Advances
and/or Servicing Advances ("Advance Reimbursement Amounts") and (c) that such
Servicer's Assignee shall agree to be bound by the provisions of this Section
5.02. The Advance Facility Notice shall be executed by the Advance Facility
Person and such Servicer's Assignee. Advance Reimbursement Amounts (i) shall
consist solely of amounts in respect of Advances and/or Servicing Advances for
which such Servicer would be permitted to reimburse itself in accordance with
Section 3.08 hereof, assuming such Servicer had made the related Advance(s)
and/or Servicing Advance(s) and (ii) shall not consist of amounts payable to a
successor Servicer in accordance with Section 3.08 hereof to the extent
permitted under Section 5.02(e) below.

            (c)   Notwithstanding the existence of an Advance Facility, a
Servicer, on behalf of the Advance Financing Person and the Servicer's Assignee,
shall be entitled to receive reimbursements of Advances and/or Servicing
Advances in accordance with Section 3.08 hereof, which entitlement may be
terminated by the Advance Financing Person pursuant to a written notice to the
Trustee and the Securities Administrator in the manner set forth in Section 5.02
hereof. Upon receipt of such written notice, such Servicer shall no longer be
entitled to receive reimbursement for any Advance Reimbursement Amounts and the
Servicer's Assignee shall immediately have the right to receive from the
Collection Account all Advance Reimbursement Amounts. Notwithstanding the
foregoing, and for the avoidance of doubt, (i) the related Servicer and/or the
Servicer's Assignee shall only be entitled to reimbursement of Advance

                                     -101-
<PAGE>

Reimbursement Amounts hereunder from withdrawals from the Collection Account
pursuant to Section 3.08 of this Agreement and shall not otherwise be entitled
to make withdrawals or receive amounts that shall be deposited in the Master
Servicer Collection Account pursuant to Section 3.06 hereof, and (ii) none of
the Trustee, the Securities Administrator or the Certificateholders shall have
any right to, or otherwise be entitled to, receive any Advance Reimbursement
Amounts to which such Servicer or Servicer's Assignee, as applicable, shall be
entitled pursuant to Section 3.08 hereof. An Advance Facility may be terminated
by the joint written direction of the related Servicer and the related Advance
Financing Person. Written notice of such termination shall be delivered to the
Trustee and the Securities Administrator in the manner set forth in Section 5.02
hereof. None of the Depositor, the Securities Administrator nor the Trustee
shall, as a result of the existence of any Advance Facility, have any additional
duty or liability with respect to the calculation or payment of any Advance
Reimbursement Amount, nor, as a result of the existence of any Advance Facility,
shall the Depositor, the Securities Administrator or the Trustee have any
additional responsibility to track or monitor the administration of the Advance
Facility or the payment of Advance Reimbursement Amounts to the Servicer's
Assignee. Each Servicer shall indemnify the Depositor, the Trustee, the Master
Servicer, the Securities Administrator, any successor Servicer and the Trust
Fund for any claim, loss, liability or damage resulting from any claim by the
related Advancing Financing Person, or Servicer's Assignee, except to the extent
that such claim, loss, liability or damage resulted from or arose out of
negligence, recklessness or willful misconduct on the part of the Depositor, the
Trustee, the Securities Administrator or any successor Servicer, as the case may
be, or a breach of any obligation under this Agreement, by the successor
Servicer. Each Servicer shall maintain and provide to any successor Servicer
and, upon request, the Trustee and the Securities Administrator a detailed
accounting on a loan-by-loan basis as to amounts advanced by, pledged or
assigned to, and reimbursed to any Advancing Financing Person. The successor
Servicer shall be entitled to rely on any such information provided by the
predecessor Servicer, and the successor Servicer shall not be liable for any
errors in such information.

            (d)   An Advance Financing Person who receives an assignment or
pledge of rights to receive Advance Reimbursement Amounts and/or whose
obligations are limited to the funding of Advances and/or Servicing Advances
pursuant to an Advance Facility shall not be required to meet the criteria for
qualification as a Sub-Servicer.

            (e)   As between a predecessor Servicer and its Advance Financing
Person, on the one hand, and a successor Servicer and its Advance Financing
Person, if any, on the other hand, Advance Reimbursement Amounts on a
loan-by-loan basis with respect to each Mortgage Loan as to which an Advance
and/or Servicing Advance shall have been made and be outstanding shall be
allocated on a "first-in, first out" basis. In the event the Servicer's Assignee
shall have received some or all of an Advance Reimbursement Amount related to
Advances and/or Servicing Advances that were made by a Person other than such
predecessor Servicer or its related Advance Financing Person in error, then such
Servicer's Assignee shall be required to remit any portion of such Advance
Reimbursement Amount to each Person entitled to such portion of such Advance
Reimbursement Amount. Without limiting the generality of the foregoing, a
Servicer shall remain entitled to be reimbursed by the Advance Financing Person
for all Advances and/or Servicing Advances funded by such Servicer to the extent
the related Advance Reimbursement Amounts have not been assigned or pledged to
such Advance Financing Person or Servicer's Assignee.

            (f)   For purposes of any certification of a Servicing Officer of a
Servicer made pursuant to Section 3.22 any Nonrecoverable Advance referred to
therein may have been made by such Servicer or any predecessor Servicer. In
making its determination that any Advance theretofore made has become a
Nonrecoverable Advance, such Servicer shall apply the same criteria in making
such determination regardless of whether such Advance shall have been made by
such Servicer or any predecessor Servicer.

            (g)   Any amendment to this Section 5.02 or to any other provision
of this Agreement that may be necessary or appropriate to effect the terms of an
Advance Facility as described generally in this Section 5.02, including
amendments to add provisions relating to a successor servicer, may be entered
into by the Trustee, the Depositor, the Securities Administrator, the Backup
Servicer and the Servicers without the consent of any Certificateholder,
provided such amendment complies with Section 11.01 hereof. All reasonable costs
and expenses (including attorneys' fees) of each party hereto of any such
amendment shall be borne solely by the Servicer requesting such amendment. The
parties hereto hereby acknowledge and agree that: (a) the Advances and/or
Servicing Advances financed by and/or pledged to an Advance Financing Person
under any Advance Facility are obligations owed to a Servicer payable only from
the cash flows and proceeds received under this Agreement for reimbursement of
Advances and/or Servicing Advances only to the extent provided herein, and the
Trustee and the Trust are not, as a result of the existence of any Advance
Facility, obligated or liable to repay any Advances and/or Servicing Advances
financed by the Advance Financing Person; (b) such Servicer will be responsible
for remitting to the Advance Financing Person the applicable amounts collected
by it as reimbursement for Advances and/or Servicing Advances funded by the
Advance Financing Person, subject to the provisions of this Agreement; and (c)
neither the Trustee nor the Securities Administrator shall have any
responsibility to track or monitor the administration of the financing
arrangement between such Servicer and any Advance Financing Person.

      SECTION 5.03. 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, beginning on the Servicing Transfer Date, each Servicer
shall, from amounts in respect of its Servicing Fee for such Distribution Date,
deposit into the Collection Account, as a reduction of the Servicing Fee for
such Distribution Date, no later than each Servicer Advance Date immediately
preceding such Distribution Date, an amount up to the Prepayment Interest
Shortfall. In case of such deposit, such Servicer shall not be entitled to any
recovery or reimbursement from the Depositor, the Trustee, the Trust Fund or the
Certificateholders. With respect to any Distribution Date, to the extent that
the Prepayment Interest Shortfall exceeds Compensating Interest (such excess, a
"Non-Supported Interest Shortfall"), such Non-Supported Interest Shortfall shall
reduce the Current Interest with respect to each Class of Certificates, pro rata
based upon the amount of interest each such Class would otherwise be entitled to
receive on such Distribution Date.

      SECTION 5.04. Distributions on the REMIC Interests.

      On each Distribution Date, amounts on deposit in the Certificate Account
shall be treated for federal income tax purposes as applied to distributions on
the interests in REMIC 1, REMIC 2, REMIC 3 and REMIC 4 in an amount sufficient
to make the distributions on the respective Certificates on such Distribution
Date in accordance with the provisions of Section 5.05.

      SECTION 5.05. Distributions.

            (a)   [RESERVED].

            (b)   On each Distribution Date, the Securities Administrator shall

Certificates, Class A-1-B Certificates, Class A-X-A Certificates and Class A-X-B

not sufficient to make a full distribution of the Current Interest and any
Interest Carryforward Amount with respect to all of the Class R Certificate,
Class A-1-A Certificates, Class A-1-B Certificates, Class A-X-A Certificates and
Class A-X-B Certificates, such amount will be distributed pro rata among each
Class R Certificate, Class A-1-A Certificates, Class A-1-B Certificates, Class
A-X-A Certificates and Class A-X-B Certificates based on the ratio of (x) the
Current Interest and Interest Carryforward Amount for each Class of Class R

Amount with respect to such Class; provided, however, if such amount is not
sufficient to make a full distribution of the Current Interest and any Interest

Certificates and Class M-1-X Certificates to (y) the total amount of Current
Interest and any Interest Carryforward Amount for the Class of Class M-1
Certificates and Class M-1-X Certificates;

                  (iii)  to the Class M-2 Certificates and the Class M-2-X
Certificates, concurrently, the Current Interest and any Interest Carryforward
Amount with respect to such Class; provided, however, if such amount is not
sufficient to make a full distribution of the Current Interest and any Interest
Carryforward Amount with respect to all of the Class M-2 Certificates and Class

M-2 Certificates and Class M-2-X Certificates based on the ratio of (x) the
Current Interest and Interest Carryforward Amount for each Class of Class M-2
Certificates and Class M-2-X Certificates to (y) the total amount of Current
Interest and any Interest Carryforward Amount for the Class of Class M-2
Certificates and Class M-2-X Certificates;

                  (iv)   to the Class M-3 Certificates and the Class M-3-X

Amount with respect to such Class; provided, however, if such amount is not
sufficient to make a full distribution of the Current Interest and any Interest
Carryforward Amount with respect to all of the Class M-3 Certificates and Class
M-3-X Certificates, such amount will be distributed pro rata among each Class
M-3 Certificates and Class M-3-X Certificates based on the ratio of (x) the

Certificates and Class M-3-X Certificates to (y) the total amount of Current
Interest and any Interest Carryforward Amount for the Class of Class M-3

            (c)   [RESERVED].

            (d)   On each Distribution Date, the Securities Administrator shall
make the following distributions from the Certificate Account of an amount equal
to the Principal Distribution Amount in the

                                     -104-

following order of priority, and each such distribution shall be made only after
all distributions pursuant to Section 5.05(b) above (excluding Section

distributed for such Distribution Date:

                  (i)    to the Class R, Class A-1-A and Class A-1-B

the Class A-1-A and Class A-1-B Certificates until their Certificate Principal
Balances have been reduced to zero.

Distribution Amount;

                  (iii)  to the Class M-2 Certificates, the Class M-2 Principal

            (i)   on each Distribution Date, the Securities Administrator shall

            (k)   Subject to Section 10.02 hereof respecting the final

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 or if the Securities Administrator has not been
provided with a Holder's wire instruction or if such Holder has provided the
Securities Administrator with written request at least five (5) Business Days
prior to the related Record Date 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.

      In accordance with this Agreement, the Servicer shall prepare and deliver
a report (the "Remittance Report") to the Trustee and the Securities
Administrator in the form of a computer readable

                                     -107-
<PAGE>

magnetic tape (or by such other means as the Master Servicer or the Servicer, as
applicable, the Securities Administrator may agree from time to time) containing
such data and information such as to permit the Trustee to prepare the Monthly
Statement to Certificateholders and make the required distributions for the
related Distribution Date.

            (l)   Any payments received under the terms of the Cap Contract will
be available to pay the holders of the Offered Certificates and Class B
Certificates up to the amount of any Floating Rate Certificate Carryover
remaining after the application of Section 5.05(f)(viii) on such Distribution
Date (other than any Floating Rate Certificate Carryover attributable to the
fact that Applied Realized Loss Amounts are not allocated to the Class A and
Class R Certificates). Any amounts in the Cap Contract Account on any
Distribution Date in excess of amounts required to pay such outstanding Floating
Rate Certificate Carryovers on such Distribution Date will be distributed to the
holders of the Class N and Class X Certificates in accordance with the
provisions of Section 5.05(i) hereof (after all other distributions have been
made thereunder on such Distribution Date). Payments from the Cap Contract
Account in respect of such Floating Rate Certificate Carryovers shall be paid to
the Offered Certificates and Class B Certificates in accordance with the
provisions of Section 5.05(f)(viii) hereof (and taking into account only
Floating Rate Certificate Carryovers other than Floating Rate Certificate
Carryover attributable to the fact that Applied Realized Loss Amounts are not
allocated to the Class A and Class R Certificates).

For any Distribution Date on which there is a payment under the Cap Contract
based on a notional balance in excess of the aggregate Certificate Principal
Balance of the Offered Certificates and the Class B Certificates, the amount
representing such excess payment, to the extent not otherwise used to pay
Floating Rate Certificate Carryovers, shall not be an asset of the Trust Fund
and, instead, shall be paid into and distributed out of a separate trust created
by this Agreement for the benefit of the Class N and Class X Certificates and
shall be distributed to the Class N and Class X Certificates pursuant to the
priorities specified in Section 5.05(i).

                  (i)    On or prior to the Cap Contract Termination Date,
amounts, if any, received by the Trustee for the benefit of the Trust Fund in
respect of the Cap Contract shall be deposited by the Trustee into the Cap
Contract Account. With respect to any Distribution Date on or prior to the Cap
Contract Termination Date, the amount, if any, payable by the Cap Contract
Counterparty under the Cap Contract will equal the product of (i) the excess of
(x) One-Month LIBOR (as determined by the Cap Contract Counterparty and subject
to a cap equal to the rate with respect to such Distribution Date as shown under
the heading "Upper Collar" in the Cap Table), over (y) the rate with respect to
such Distribution Date as shown under the heading "Lower Collar" in the Cap
Table, (ii) an amount equal to the Cap Contract Notional Balances and (iii) the
number of days in such Accrual Period, divided by 360. If a payment is made to
the Trust Fund under the Cap Contract and the Trustee intends to distribute
excess amounts to the holders of the Class N and Class X Certificates as
described above, the Trustee shall send a notice on the Business Day prior to
the related Distribution Date stating the amount received on the Cap Contract,
the amount paid with respect to Floating Rate Certificate Carryovers (other than
any Floating Rate Certificate Carryover attributable to the fact that Applied
Realized Loss Amounts are not allocated to the Class A and Class R Certificates)
and the amount due to the holders of the Class N and Class X Certificates. Such
notice shall be sent by the Trustee via facsimile to the holders of the Class N
and Class X Certificates.

                  (ii)   Amounts on deposit in the Cap Contract Account will
remain uninvested pending distribution to Certificateholders.

The Cap Contract is scheduled to remain in effect until the Cap Contract
Termination Date and will be subject to early termination only in limited
circumstances. Such circumstances include certain insolvency

                                     -108-
<PAGE>

or bankruptcy events in relation to the Cap Contract Counterparty (after a grace
period of three Local Business Days, as defined in the Cap Contract, after
notice of such failure is received by the Cap Contract Counterparty) to make a
payment due under the Cap Contract, the failure by the Cap Contract Counterparty
or the Trustee (after a cure period of 20 days after notice of such failure is
received) to perform any other agreement made by it under the Cap Contract, the
termination of the Trust Fund and the Cap Contract becoming illegal or subject
to certain kinds of taxation.

      SECTION 5.06. Monthly Statements to Certificateholders.

            (a)   Not later than each Distribution Date based on information
provided by the Master Servicer or Servicer, as applicable, the Securities
Administrator shall prepare and make available on its website located at
www.jpmorgan.com/sfr to each Holder of a Class of Certificates of the Trust
Fund, the Master Servicer, the Trustee, each Servicer, the Rating Agencies and
the Depositor a statement setting forth for each $1,000 principal amount of
Certificates:

each Class allocable to principal, separately identifying (A) the aggregate
amount of any Principal Prepayments included therein, (B) the aggregate of all
scheduled payments of principal included therein, (C) the Extra Principal
Distribution Amount, if any, and (D) the aggregate amount of prepayment
penalties, if any;

                  (ii)   the amount of such distribution to Holders of each
Class allocable to interest, together with any Non-Supported Interest Shortfalls
allocated to each Class;

                  (iii)  any Interest Carryforward Amount for each Class of the
Certificates;

      SECTION 5.07. Pre-Funding Account.

            (a)   No later than the Closing Date, the Securities Administrator
shall establish and maintain on behalf of the Trustee for the benefit of the
Certificateholders a segregated trust account that is an Eligible Account, which
shall be titled "Pre-Funding Account, U.S. Bank National Association, as trustee
for the registered holders of Terwin Mortgage Trust 2004-3HE, Asset-Backed
Certificates, TMTS Series 2004-3HE" (the "Pre-Funding Account"). The Securities
Administrator, as agent for the Trustee, shall, promptly upon receipt, deposit
in the Pre-Funding Account and retain therein the Original Pre-Funded Amount
remitted on the Closing Date to the Trustee by the Seller. Funds deposited in
the Pre-Funding Account shall be held in trust by the Trustee on behalf of the
Certificateholders for the uses and purposes set forth herein. The Trustee
hereby appoints the Securities Administrator as its agent in connection with
establishing and maintaining the Pre-Funding Account pursuant to this Section
5.07.

            (b)   The Securities Administrator shall invest funds deposited in
the Pre-Funding Account in Permitted Investments as directed in writing by the
Seller (provided that if the Securities Administrator does not receive written
direction from the Seller, then amounts in the Pre-Funding Account shall not be
invested) with a maturity date no later than the Business Day preceding each
Distribution Date or Subsequent Transfer Date, as the case may be. For federal
income tax purposes, the Seller shall be the owner of the Pre-Funding Account
and shall report all items of income, deduction, gain or loss arising therefrom.
All income and gain realized from investment of funds deposited in the
Pre-Funding Account shall be transferred to the Capitalized Interest Account on
the Business Day immediately preceding each Distribution Date or Subsequent
Transfer Date, as the case may be. The Seller shall deposit in the Pre-Funding
Account the amount of any net loss incurred in respect of any such Permitted
Investment immediately upon realization of such loss without any right of
reimbursement therefor. The Pre-Funding Account will not be an asset of any of
the REMICs provided for herein.

            (c)   Amounts on deposit in the Pre-Funding Account shall be
withdrawn by the Securities Administrator as follows:

                  (i)    On any Subsequent Transfer Date, the Securities
Administrator shall withdraw from the Pre-Funding Account an amount equal to
100% of the aggregate Stated Principal Balances of the Subsequent Mortgage Loans
transferred and assigned to the Trustee for deposit in the Mortgage Pool on such
Subsequent Transfer Date and pay such amount to or upon the order of the
Depositor upon satisfaction of the conditions set forth in Section 2.11 with
respect to such transfer and assignment;

                  (ii)   To withdraw any amount not required to be deposited in
the Pre-Funding Account or deposited therein in error; and

                  (iii)  To clear and terminate the Pre-Funding Account upon the
earlier to occur of (A) the Distribution Date in the month immediately following
the end of the Funding Period and (B) the termination of this Agreement, with
any amounts remaining on deposit therein being deposited into the Certificate
Account for distribution in accordance with the terms thereof.

      SECTION 5.08. Capitalized Interest Account.

            (a)   No later than the Closing Date, the Securities Administrator,
on behalf of the Trustee, shall establish and maintain a segregated trust
account that is an Eligible Account, which shall be titled "Capitalized Interest
Account, U.S. Bank National Association, as trustee for the registered holders
of Terwin Mortgage Trust 2004-3HE, Asset-Backed Certificates, TMTS Series
2004-3HE" (the "Capitalized Interest Account"). The Trustee shall, promptly upon
receipt, deposit in the Capitalized Interest Account and retain therein the
Capitalized Interest Amount remitted on the Closing Date to the

                                     -112-
<PAGE>

Trustee by the Depositor. Funds deposited in the Capitalized Interest Account
shall be held in trust by the Trustee on behalf of the Certificateholders for
the uses and purposes set forth herein. The Trustee hereby appoints the
Securities Administrator as its agent in connection with establishing and
maintaining the Capitalized Interest Account pursuant to this Section 5.08. With
respect to each Distribution Date prior to the Distribution Date in August 2004,
the Securities Administrator will withdraw from the Capitalized Interest Account
and deposit into the Certificate Account an amount equal to the Required
Withdrawal. The Seller is required to deposit into the Capitalized Interest
Account an amount sufficient to permit the Securities Administrator to make the
withdrawals required by this Section 5.08.

            (b)   The Securities Administrator will invest funds deposited in
the Capitalized Interest Account in Permitted Investments as directed in writing
by the Seller (provided that if the Securities Administrator does not receive
written direction from the Seller, then amounts in the Capitalized Interest
Account shall not be invested) with a maturity date no later than the Business
Day preceding each Distribution Date. For federal income tax purposes, the
Seller shall be the owner of the Capitalized Interest Account and shall report
all items of income, deduction, gain or loss arising therefrom. At no time will
the Capitalized Interest Account be an asset of any of the REMICs provided for
herein. All income and gain realized from investment of funds deposited in the
Capitalized Interest Account shall be for the sole and exclusive benefit of the
Seller and shall be remitted by the Securities Administrator to the Seller on
each Distribution Date. The Seller shall deposit in the Capitalized Interest
Account the amount of any net loss incurred in respect of any such Permitted
Investment immediately upon realization of such loss.

      Upon the earliest of (i) the Distribution Date immediately following the
end of the Funding Period and (ii) the termination of this Agreement in
accordance with Section 10.01, any amount remaining on deposit in the
Capitalized Interest Account after withdrawals pursuant to paragraph (a) above

      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 Trust Fund, 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 Authenticating Agent 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 Authenticating Agent shall authenticate
the Certificates to be issued at the written direction of the Depositor, or any
Affiliate thereof.

which shall be deposited on behalf of the Holders of such Certificates
represented thereby with the Securities Administrator, as custodian for DTC and
registered in the name of a nominee of DTC, duly executed and authenticated by
the Securities Administrator and the Authenticating Agent as hereinafter
provided. The aggregate principal amounts of the Book-Entry Regulation S Global
Securities may from time to time be increased or decreased by adjustments made
on the records of the Securities Administrator or DTC or its nominee, as the
case may be, as hereinafter provided.

      The Class N or Class X Certificates sold in offshore transactions in

Security"), which shall be delivered to the Holders of such Certificates
represented thereby by the Securities Administrator, duly executed and
authenticated by the Securities Administrator and the Authenticating Agent as
hereinafter provided. The aggregate principal amounts of the Definitive
Regulation S Global Securities may from time to time be increased or decreased
by adjustments made on the records of the Securities Administrator, as
hereinafter provided.

      SECTION 6.02. Appointment of Certificate Registrar; Certificate Register;
Registration of Transfer and Exchange of Certificates.

            (a)   The Securities Administrator is hereby appointed Certificate
Registrar (the "Certificate Registrar") and in such capacity, it shall maintain,
or cause to be maintained in accordance with the provisions of Section 6.09
hereof, a Certificate Register for the Trust Fund in which, subject to the
provisions of subsections (b) and (c) below and to such reasonable regulations
as it may prescribe, the Securities Administrator 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 Authenticating Agent 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 Securities Administrator. Whenever any
Certificates are so surrendered for exchange, the Securities Administrator shall
execute and the Authenticating Agent shall 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 Securities Administrator 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 a Securities Administrator in accordance
with such Securities Administrator's customary procedures.

      No Transfer of a Class N or Class X 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 laws, in order to assure compliance with the
Securities Act and such laws, the Certificateholder desiring to effect such
Transfer and such Certificateholder's prospective transferee shall (except with
respect to the initial transfer of a Class N or Class X Certificate by Merrill
Lynch & Co.) each certify to the Securities Administrator in writing the facts
surrounding the Transfer in substantially the forms set forth in Exhibit F (the
"Transferor Certificate") and (i) deliver a letter in substantially the form of
either Exhibit G (the "Investment Letter") or Exhibit H (the "Rule 144A Letter")
or (ii) there shall be delivered to the Securities Administrator an Opinion of
Counsel that such Transfer may be made pursuant to an exemption from the
Securities Act, which Opinion of Counsel shall not be an expense of the
Depositor, the Securities Administrator or the Trustee. The Depositor shall
provide to any Holder of a Class N or Class X 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
Securities Administrator shall cooperate with the Depositor in providing the
Rule 144A information referenced in the preceding sentence, including providing
to the Depositor such information in the possession of the Securities
Administrator 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 Class N or Class X
Certificate desiring to effect such Transfer shall, and does hereby agree to,
indemnify the Depositor, the Securities Administrator and the Trustee against

                                     -115-
<PAGE>

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

      By acceptance of a Regulation S Global Security, whether upon original
issuance or subsequent transfer, each Holder of such a Certificate acknowledges
the restrictions on the transfer of such Certificate set forth thereon and
agrees that it will only transfer such a Certificate as provided herein. In
addition, each Holder of a Regulation S Global Security shall be deemed to have
represented and warranted to the Depositor, the Securities Administrator and any
of their respective successors that: (i) such Person is not a "U.S. person"
within the meaning of Regulation S and was, at the time the buy order was
originated, outside the United States and (ii) such Person understands that such
Certificates have not been registered under the Securities Act and that (x)
until the expiration of the 40-day distribution compliance period (within the
meaning of Regulation S), no offer, sale, pledge or other transfer of such
Certificates or any interest therein shall be made in the United States or to or
for the account or benefit of a U.S. person (each as defined in Regulation S),
(y) if in the future it decides to offer, resell, pledge or otherwise transfer
such Certificates, such Certificates may be offered, resold, pledged or
otherwise transferred only (A) to a person which the seller reasonably believes
is a "qualified institutional buyer" (a "QIB") as defined in Rule 144A under the
Securities Act, that is purchasing such Certificates for its own account or for
the account of a qualified institutional buyer to which notice is given that the
transfer is being made in reliance on Rule 144A or (B) in an offshore
transaction (as defined in Regulation S) in compliance with the provisions of
Regulation S, in each case in compliance with the requirements of this
Agreement; and it will notify such transferee of the transfer restrictions
specified in this Section.

      No Transfer of a Class N or Class X Certificate, or a beneficial interest
therein, may be made to a non-United States Person unless the Securities
Administrator has received, in the manner required by applicable United States
Treasury Regulations (and with all required attachments, including, where the
non-United States Person is providing an Internal Revenue Service Form W-8IMY
(or any successor form), Internal Revenue Service Forms W-8BEN or W-9 (or any
successor forms) from all persons treated as beneficially owning an interest in
the Class N or Class X Certificate through such non-United States Person either
directly, through an intermediary or through an entity that is treated as a
partnership or other look-through entity for non-United States federal tax
purposes), a properly completed Internal Revenue Service Form W-8IMY, W-8BEN or
W-8ECI (or any successor form) from such non-United States Person.

      No Transfer of an ERISA Restricted Certificate shall be made unless the
Securities Administrator shall have received a representation from the
transferee of such Certificate acceptable to and in form and substance
satisfactory to the Securities Administrator, to the effect that such transferee
is not an employee benefit plan subject to Title I of ERISA or a plan subject to
Section 4975 of the Code or a plan subject to any applicable Federal, state or
local law materially similar to the foregoing provisions of ERISA and the Code
("Similar Law"), or a Person acting on behalf of any such plan or using the
assets of any such plan. For purposes of the preceding sentence, such
representation shall be deemed to have been made to the Securities Administrator
by the transferee's acceptance of an ERISA Restricted Certificate (or the
acceptance by a Certificate Owner of the beneficial interest in any Class of
ERISA Restricted Certificates) unless the Securities Administrator shall have
received from the transferee an alternative representation acceptable in form
and substance to the Securities Administrator. 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 Title I of ERISA, a plan
subject to Section 4975 of the Code, or a plan subject to Similar Law shall be
void and of no effect. The Securities Administrator 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 6.02(a) 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 by the Securities Administrator in
accordance with the foregoing requirements.

                                     -116-

The Securities Administrator shall be entitled, but not obligated, to recover
from any Holder of any ERISA Restricted Certificate that was in fact an employee
benefit plan subject to Title I of ERISA, a plan subject to Section 4975 of the
Code, or a plan subject to Similar Law or a Person acting on behalf of any such
plan at the time it became a Holder or, at such subsequent time as it became
such a plan or Person acting on behalf of such a plan, all payments made on such
ERISA Restricted Certificate at and after either such time. Any such payments so
recovered by the Securities Administrator shall be paid and delivered by the
Securities Administrator to the last preceding Holder of such Certificate that
is not such a plan or Person acting on behalf of a plan.

            (b)   Each Person who has or who acquires any Ownership Interest in
a Class 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 R
Certificate are expressly subject to the following provisions:

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

                  (ii)   No Ownership Interest in a Class R Certificate may be
purchased, transferred or sold, directly or indirectly, except in accordance
with the provisions hereof. No Ownership Interest in a Class R Certificate may
be registered on the Closing Date or thereafter transferred, and the Securities
Administrator shall not register the Transfer of any Class R Certificate unless,
in addition to the certificates required to be delivered to the Securities
Administrator under subparagraph (b) above, the Securities Administrator 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 E-1 and
an affidavit of the proposed transferor in the form attached hereto as Exhibit
E-2. In the absence of a contrary instruction from the transferor of a Class R
Certificate, declaration (11) in Appendix A of the Transfer Affidavit may be
left blank. If the transferor requests by written notice to the Securities
Administrator prior to the date of the proposed transfer that one of the two
other forms of declaration (11) in Appendix A of the Transfer Affidavit be used,
then the requirements of this Section 6.02(b)(ii) shall not have been satisfied
unless the Transfer Affidavit includes such other form of declaration.

                  (iii)  Each Person holding or acquiring any Ownership Interest
in a Class 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 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 R Certificate and (C) not to Transfer its Ownership Interest
in a Class R Certificate or to cause the Transfer of an Ownership Interest in a
Class R Certificate to any other Person if it has actual knowledge that such
Person is not a Permitted Transferee. Further, no transfer, sale or other
disposition of any Ownership Interest in a Class R Certificate may be made to a
person who is not a U.S. Person (within the meaning of section 7701 of the Code)
unless such person furnishes the transferor, the Securities Administrator with a
duly completed and effective Internal Revenue Service Form W-8ECI (or any
successor thereto) and the Securities Administrator consents to such transfer,
sale or other disposition in writing.

                  (iv)   Any attempted or purported Transfer of any Ownership
Interest in a Class R Certificate in violation of the provisions of this Section
5.02(b) 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 R Certificate in violation of the provisions of this Section 5.02(b), 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
R Certificate. The Securities Administrator shall be under no liability to any

                                     -117-
<PAGE>

Person for any registration of Transfer of a Class R Certificate that is in fact
not permitted by Section 5.02(a) and 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 Transfer was registered after receipt of the related Transfer
Affidavit. The Securities Administrator shall be entitled but not obligated to
recover from any Holder of a Class 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
R Certificate at and after either such time. Any such payments so recovered by
the Securities Administrator shall be paid and delivered by the Securities
Administrator to the last preceding Permitted Transferee of such Certificate.

                  (v)    At the option of the Holder of the Class R Certificate,
the Class LT1-R Interest, the Class LT2-R Interest, the Class LT3-R Interest and
the REMIC 4 Residual Interest may be severed and represented by separate
certificates (with the separate certificate that represents the REMIC 4 Residual
Interest also representing all rights of the Class R Certificate to
distributions attributable to a Pass-Through Rate on the Class R Certificate in
excess of the Adjusted Net WAC); provided, however, that such separate
certification may not occur until the Securities Administrator receives an
Opinion of Counsel to the effect that separate certification in the form and
manner proposed would not result in the imposition of federal tax upon the Trust
Fund or any of the REMICs provided for herein or cause any of the REMICs
provided for herein to fail to qualify as a REMIC; and provided further, that
the provisions of Sections 5.02(a) and (b) will apply to each such separate
certificate as if the separate certificate were a Class R Certificate. If, as
evidenced by an Opinion of Counsel, it is necessary to preserve the REMIC status
of any of the REMICs provided for herein, the Class LT1-R Interest, the Class
LT2-R Interest, the Class LT3-R Interest and the REMIC 4 Residual Interest shall
be severed and represented by separate certificates (with the separate
certificate that represents the REMIC 4 Residual Interest also representing all
rights of the Class R Certificate to distributions attributable to a
Pass-Through Rate on the Class R Certificate in excess of the Adjusted Net WAC).

      The restrictions on Transfers of a Class R Certificate set forth in this
Section 5.02(b) shall cease to apply (and the applicable portions of the legend
on a Class R Certificate may be deleted) with respect to Transfers occurring
after delivery to the Securities Administrator of an Opinion of Counsel, which
Opinion of Counsel shall not be an expense of the Securities Administrator or
the Depositor, to the effect that the elimination of such restrictions will not
cause any of the REMICs provided for herein 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, any REMIC provided for herein, a Certificateholder or
another Person. Each Person holding or acquiring any Ownership Interest in a
Class R Certificate hereby consents to any amendment of this Agreement that,
based on an Opinion of Counsel furnished to the Securities Administrator, is
reasonably necessary (a) to ensure that the record ownership of, or any
beneficial interest in, a Class 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 R Certificate that is held by a
Person that is not a Permitted Transferee to a Holder that is a Permitted
Transferee.

            (c)   The transferor of the Class R Certificate shall notify the
Securities Administrator in writing upon the transfer of the Class R
Certificate.

            (d)   The preparation and delivery of all certificates, opinions and
other writings referred to above in this Section 6.02 shall not be an expense of
the Trust Fund, the Depositor, the Securities Administrator or the Trustee.

                                     -118-

      SECTION 6.03. Mutilated, Destroyed, Lost or Stolen Certificates.

      If (a) any mutilated Certificate is surrendered to the Securities
Administrator or the Securities Administrator 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 Securities Administrator 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 Securities Administrator
that such Certificate has been acquired by a bona fide purchaser, the Securities
Administrator 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 Securities
Administrator 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 Securities Administrator and
the Trustee and their counsel) 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 Securities Administrator under the terms of this
Section 5.03 shall be canceled and destroyed by the Securities Administrator in
accordance with its standard procedures without liability on its part.

      SECTION 6.04. Persons Deemed Owners.

      The Trustee, the Securities Administrator and any agent of the Trustee or
the Securities Administrator 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 Trustee or the Securities Administrator, nor any
agent of the Trustee or the Securities Administrator shall be affected by any
notice to the contrary.

      SECTION 6.05. Access to List of Certificateholders' Names and Addresses.

      If three or more Certificateholders (a) request such information in
writing from the Securities Administrator, (b) state that such
Certificateholders desire to communicate with other Certificateholders with
respect to their rights under this Agreement or under the Certificates, and (c)
provide a copy of the communication that such Certificateholders propose to
transmit or if the Depositor shall request such information in writing from the
Securities Administrator, then the Securities Administrator shall, within ten
Business Days after the receipt of such request, provide the Depositor or such
Certificateholders at such recipients' expense the most recent list of the
Certificateholders of the Trust Fund held by the Securities Administrator, if
any. The Depositor and every Certificateholder, by receiving and holding a
Certificate, agree that the Securities Administrator 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 6.06. Book-Entry Certificates.

      The Regular Certificates, upon original issuance, shall be issued in the
form of one or more typewritten Certificates representing the Book-Entry
Certificates, to be delivered to the Depository by or on behalf of the
Depositor. The Class N, Class R and Class X Certificates shall be definitive
certificates. The Book-Entry Certificates shall initially be registered on the
Certificate Register in the name of the Depository or its nominee, and no
Certificate Owner of a Book-Entry Certificate will receive a definitive
certificate representing such Certificate Owner's interest in such Certificates,
except as provided in Section 6.08. Unless and until definitive, fully
registered Certificates ("Definitive Certificates") have been issued to the
Certificate Owners of the Book-Entry Certificates pursuant to Section 6.08:

                                     -119-
<PAGE>

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

            (b)   the Depositor, the Securities Administrator 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 the Book-Entry Certificates;

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

            (d)   the rights of the respective Certificate Owners of the
Book-Entry 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 the Book-Entry Certificates and the Depository
and/or the Depository Participants. Pursuant to the Depository Agreement, unless
and until Definitive Certificates are issued pursuant to Section 6.08, 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 Securities Administrator and 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 6.07. 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 Securities Administrator and the
Trustee shall give all such notices and communications to the Depository.

      SECTION 6.08. Definitive Certificates.

      If, after Book-Entry Certificates have been issued with respect to any
Certificates, (a) the Depository or the Depositor advises the Securities
Administrator and the Trustee that the Depository is no longer willing,
qualified or able to discharge properly its responsibilities under the
Depository Agreement with respect to such Certificates and the Securities
Administrator or the Depositor is unable to locate a qualified successor, (b)
the Depositor, at its sole option, advises the Securities Administrator and the
Trustee that it elects to terminate the book-entry system with respect to such
Certificates through the Depository or (c) 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 Securities Administrator, 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

                                     -120-
<PAGE>

Owners of such Class, then the Securities Administrator shall notify all
Certificate Owners of such Book-Entry 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 Securities Administrator with an adequate inventory
of certificates to facilitate the issuance and transfer of Definitive
Certificates. Upon surrender to the Securities Administrator of any such
Certificates by the Depository, accompanied by registration instructions from
the Depository for registration, the Authenticating Agent shall authenticate and
the Securities Administrator shall deliver such Definitive Certificates. Neither
the Depositor nor the Securities Administrator 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 Securities Administrator, to the extent applicable with respect to such
Definitive Certificates and the Securities Administrator shall recognize the
Holders of such Definitive Certificates as Certificateholders hereunder.

      SECTION 6.09. Maintenance of Office or Agency.

      The Securities Administrator will maintain or cause to be maintained at
its expense an office or offices or agency or agencies where Certificates may be
surrendered for registration of transfer or exchange. The Securities
Administrator initially designates its offices at 2001 Bryan Street, 10th Floor,
Dallas, Texas 75201, Attention: Institutional Trust Services, Terwin Mortgage
Trust 2004-3HE as offices for such purposes. The Securities Administrator will
give prompt written notice to the Certificateholders of any change in such
location of any such office or agency.

      SECTION 6.10. Authenticating Agents.

            (a)   The Trustee may appoint one or more Authenticating Agents
(each, an "Authenticating Agent") which shall be authorized to act on behalf of
the Trustee in authenticating the Certificates. Wherever reference is made in
this Agreement to the authentication of Certificates by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication on behalf of the Trustee by an Authenticating Agent and a
certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent must be an entity organized and
doing business under the laws of the United States of America or of any state,
having a combined capital and surplus of at least $15,000,000, authorized under
such laws to do a trust business and subject to supervision or examination by
federal or state authorities. If the Authenticating Agent is a party other than
the Trustee, the Trustee shall have no liability in connection with the
performance or failure of performance of the Authenticating Agent. The Trustee
hereby appoints JPMorgan as the initial Authenticating Agent. The Trustee shall
be the Authenticating Agent during any such time as no other Authenticating
Agent has been appointed and has not resigned.

            (b)   Any Person into which any Authenticating Agent may be merged
or converted or with which it may be consolidated, or any Person resulting from
any merger, conversion or consolidation to which any Authenticating Agent shall
be a party, or any Person succeeding to the corporate agency business of any
Authenticating Agent, shall continue to be the Authenticating Agent without the
execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent.

            (c)   Any Authenticating Agent may at any time resign by giving at
least 30 days' advance written notice of resignation to the Trustee and the
Depositor. The Trustee may at any time terminate the agency of any
Authenticating Agent by giving written notice of termination to such
Authenticating Agent and the Depositor. Upon receiving a notice of resignation
or upon such a termination, or in case at any time any Authenticating Agent
shall cease to be eligible in accordance

                                     -121-
<PAGE>

within the provisions of this Section 6.10, the Trustee may appoint a successor
Authenticating Agent, shall give written notice of such appointment to the
Depositor and shall mail notice of such appointment to all Holders of
Certificates. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers, duties
and responsibilities of its predecessor hereunder, with like effect as if
originally named as Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section 6.10. No
Authenticating Agent shall have responsibility or liability for any action taken
by it as such at the direction of the Trustee. Any Authenticating Agent (except
the Securities Administrator) shall be entitled to reasonable compensation for
its services and any such compensation shall be payable solely by the Trust
Fund, without any right of reimbursement from the Depositor, each Servicer, the
Securities Administrator, the Master Servicer or the Trustee; provided that the
Securities Administrator shall not be entitled to any additional compensation
for serving as Authenticating Agent.

       THE DEPOSITOR, THE MASTER SERVICER, THE SERVICER AND THE SECURITIES
                                  ADMINISTRATOR

      SECTION 7.01. Respective Liabilities of the Depositor, the Master
Servicer, each Servicer and the Securities Administrator.

      The Depositor, the Master Servicer, each Servicer and the Securities
Administrator 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 7.02. Merger or Consolidation of the Depositor, the Master
Servicer, each Servicer or the Securities Administrator.

      Except as provided in the next paragraph, the Depositor, the Master
Servicer, each Servicer and the Securities Administrator will each keep in full
effect its existence, rights and franchises as a corporation or banking
association 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 respective duties under this Agreement.

      Any Person into which the Depositor, the Master Servicer, each Servicer or
the Securities Administrator may be merged or consolidated, or any Person
resulting from any merger or consolidation to which the Depositor, the Master
Servicer, each Servicer or the Securities Administrator shall be a party, or any
Person succeeding to the business of the Depositor, the Master Servicer, each
Servicer or the Securities Administrator, shall be the successor of the
Depositor, the Master Servicer or Servicer, 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
(except for the execution of an assumption agreement where such succession is
not effected by operation of law); provided, however, that the successor or
surviving Person to each Servicer shall be qualified to sell mortgage loans to,
and to service mortgage loans on behalf of, Fannie Mae or Freddie Mac.

      SECTION 7.03. Limitation on Liability of the Depositor, Master Servicer,
each Servicer, the Backup Servicer, the Trustee, the Securities Administrator
and Others.

Servicer, the Trustee, the Securities Administrator nor any of the directors,
officers, employees or agents of the Depositor, the Master Servicer, each
Servicer, the Backup Servicer, the Trustee or the Securities Administrator shall
be under any liability to the Trust Fund or the Certificateholders for any

pursuant to this Agreement, or for errors in judgment; provided, however, that
this provision shall not protect the Depositor, the Master Servicer, each
Servicer, the Backup Servicer, the Trustee, the Securities Administrator or any
such Person against any breach of representations or warranties made by it
herein or protect the Depositor, the Master Servicer, each Servicer, the Backup
Servicer, the Trustee, the Securities Administrator or any such Person from any
liability that would otherwise be imposed by reasons of willful misfeasance, bad
faith or negligence in the performance of duties or by reason of reckless
disregard of obligations and duties hereunder. The Depositor, the Master
Servicer, each Servicer, the Backup Servicer, the Trustee or the Securities
Administrator and any director, officer, employee or agent of the Depositor, the
Master Servicer, each Servicer, the Backup Servicer, the Trustee or the
Securities Administrator may rely in good faith on any document of any kind

employee or agent of the Depositor, the Master Servicer, each Servicer, the
Backup Servicer, the Trustee or the Securities Administrator shall be

relating to this Agreement or the Certificates, other than any loss, liability
or expense incurred by reason of willful misfeasance, bad faith or negligence in
the performance of duties hereunder or by reason of reckless disregard of
obligations and duties hereunder. None of the Depositor, the Master Servicer,
each Servicer, the Backup Servicer, the Trustee nor the Securities Administrator
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, however, that any
of the Depositor, the Master Servicer, each Servicer, the Backup Servicer, the
Trustee or the Securities Administrator 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

shall be entitled to be reimbursed therefor out of the Collection Account as

      In addition, the Master Servicer, the Backup Servicer, the Trustee and

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 Master Servicer, the Backup Servicer, Trustee
or Securities Administrator acting in its capacity as Master Servicer or
Securities Administrator hereunder and (B) to the extent that the Securities
Administrator or 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, in the absence of a
breach or default by any party hereto, the reasonable compensation, expenses and
disbursements of such persons), except any such compensation, expense,
disbursement or advance that either (i) arises from its negligence, bad faith or

                                     -123-
<PAGE>

willful misconduct or (ii) does not constitute an "unanticipated expense" within
the meaning of Treasury Regulations Section 1.860G-1(b)(3)(ii).

      On each Distribution Date, the Securities Administrator shall be entitled
to the Administrator Fee as compensation for its services hereunder.

      SECTION 7.04. Limitation on Resignation of the Servicers.

      A Servicer shall not resign from the obligations and duties hereby imposed
on it except upon determination that its duties hereunder are no longer
permissible under applicable law. Any such determination permitting the
resignation of a Servicer shall be evidenced by an Opinion of Counsel to such
effect delivered to the Trustee and the Securities Administrator. No such
resignation shall become effective until the Securities Administrator or a
successor servicer reasonably acceptable to the Securities Administrator is
appointed and has assumed such Servicer's responsibilities, duties, liabilities
and obligations hereunder. Any such resignation shall not relieve each Servicer
of any of the obligations specified in Sections 7.01 and 7.02 as obligations
that survive the resignation or termination of each Servicer.

      The Securities Administrator and the Depositor hereby specifically (i)
consent to the pledge and assignment by each Servicer of all each Servicer's
right, title and interest in, to and under this Agreement to the Servicing
Rights Pledgee, for the benefit of certain lenders, and (ii) agree that upon
delivery to the Trustee by the Servicing Rights Pledgee of a letter signed by
each Servicer whereby each Servicer shall resign as Servicer under this
Agreement, the Trustee shall appoint the Servicing Rights Pledgee or its
designee as successor Servicer, provided that at the time of such appointment,
the Servicing Rights Pledgee or such designee meets the requirements of a
successor Servicer as set forth herein and agrees to be subject to the terms of
this Agreement. If, pursuant to any provision hereof, the duties of each
Servicer are transferred to a successor Servicer, the entire amount of the
Servicing Fee and other compensation payable to each Servicer pursuant hereto
shall thereafter be payable to such successor Servicer.

      SECTION 7.05. Errors and Omissions Insurance; Fidelity Bonds.

      Each Servicer shall maintain with responsible companies, at its own
expense, a blanket Fidelity Bond and an Errors and Omissions Insurance Policy,
with broad coverage on all officers, employees or other persons acting in any
capacity requiring such persons to handle funds, money, documents or papers
relating to the related Mortgage Loans ("Servicer Employees"). Any such Fidelity
Bond and Errors and Omissions Insurance Policy shall protect and insure the
related Servicer against losses, including forgery, theft, embezzlement, fraud,
errors and omissions and negligent acts of the Servicer Employees. Each Fidelity
Bond and Errors and Omissions Insurance Policy also shall protect and insure the
related Servicer against losses in connection with the release or satisfaction
of a related Mortgage Loan without having obtained payment in full of the
indebtedness secured thereby. No provision of this Section 3.19 requiring such
Fidelity Bond and Errors and Omissions Insurance Policy shall diminish or
relieve the related Servicer from its duties and obligations as set forth in
this Agreement. The minimum coverage under any such bond and insurance policy
shall be at least equal to the corresponding amounts required by FNMA. Each
Servicer will furnish a copy of the Fidelity Bond or Errors and Omissions
Insurance Policy to the Trustee upon request.

      SECTION 7.06. Limitation on Resignation of the Master Servicer and the
Backup Servicer.

      Neither the Master Servicer nor the Backup Servicer shall resign from the
obligations and duties hereby imposed on it except upon determination that its
duties hereunder are no longer permissible under applicable law or unless a
successor servicer has been appointed. Any such determination permitting the

                                     -124-
<PAGE>

resignation of the Master Servicer or the Backup Servicer shall be evidenced by
an Opinion of Counsel at the expense of the Master Servicer or the Backup
Servicer, as applicable, to such effect delivered to the Trustee and the
Securities Administrator. No such resignation shall become effective until a
successor Master Servicer or successor Backup Servicer reasonably acceptable to
the Securities Administrator is appointed and has assumed the Master Servicer's
or the Backup Servicer's, as applicable, responsibilities, duties, liabilities
and obligations hereunder. Any such resignation shall not relieve the Master
Servicer or the Backup Servicer of any of the obligations specified in Sections
7.01 and 7.02 as obligations that survive the resignation or termination of the
Master Servicer or the Backup Servicer.

      SECTION 7.07. Assignment of Master Servicing.

      The Master Servicer may sell and assign its rights and delegate its duties
and obligations in its entirety as Master Servicer under this Agreement;
provided, however, that, prior to the Servicing Transfer Date: (i) any purchaser
or transferee must accept in writing such assignment and delegation and assume
the obligations of the Master Servicer hereunder shall (a) be a Person which
shall be qualified to service mortgage loans for Fannie Mae or Freddie Mac or a
Person who has an Affiliate who is qualified; (b) have a net worth of not less
than $15,000,000 (unless otherwise approved by each Rating Agency pursuant to
clause (ii) below); (c) be reasonably satisfactory to the Trustee and the
Depositor; and (d) execute and deliver to the Trustee an agreement, in form and
substance reasonably satisfactory to the Trustee, which contains an assumption
by such Person of the due and punctual performance and observance of each
covenant and condition to be performed or observed by it as master servicer
under this Agreement, any custodial agreement from and after the effective date
of such agreement; (ii) each Rating Agency shall be given prior written notice
of the identity of the proposed successor to the Master Servicer and each Rating
Agency's rating of the Certificates in effect immediately prior to such
assignment, sale and delegation will not be downgraded, qualified or withdrawn
as a result of such assignment, sale and delegation, as evidenced by a letter to
such effect delivered to the Master Servicer and the Trustee; and (iii) the
Master Servicer assigning and selling the master servicing shall deliver to the
Trustee an officer's certificate and an Independent opinion of counsel, each
stating that all conditions precedent to such action under this Agreement have
been completed and such action is permitted by and complies with the terms of
this Agreement. No such assignment or delegation shall affect any liability of
the Master Servicer arising out of acts or omissions prior to the effective date
thereof.

      SECTION 7.08. Limitation Upon Liability of the Credit Risk Manager.

      Neither the Credit Risk Manager, nor any of its directors, officers,
employees, or agents shall be under any liability to the Trust Fund or the
Certificateholders, for any action taken or for refraining from the taking of
any action made in good faith pursuant to this Agreement or the Credit Risk
Management Agreement, in reliance upon information provided by each Servicer
under the Credit Risk Management Agreement, or for errors in judgment; provided,
however, that this provision shall not protect the Credit Risk Manager or any
such person against liability that would otherwise be imposed by reason of
willful malfeasance, gross negligence or bad faith in its performance of its
duties or by reason of reckless disregard for its obligations and duties under
this Agreement or the applicable Credit Risk Management Agreement. The Credit
Risk Manager and any director, officer, employee, or agent of the Credit Risk
Manager 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,
and may rely in good faith upon the accuracy of information furnished by each
Servicer pursuant to the Credit Risk Management Agreement in the performance of
its duties thereunder and hereunder.

                                  ARTICLE VIII

                        DEFAULT; TERMINATION OF SERVICER

      SECTION 8.01. Events of Default.

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

                  (i)    any failure by each Servicer to make any Advance, to
deposit in the Collection Account or the Certificate Account or remit to the
Securities Administrator any payment (excluding a payment required to be made
under Section 5.01 hereof) required to be made under the terms of this
Agreement, which failure shall continue unremedied for three Business Days and,
with respect to a payment required to be made under Section 5.01 hereof, for one
Business Day, after the date on which written notice of such failure shall have
been given to each Servicer by the Securities Administrator or the Depositor, or
to the Securities Administrator and each Servicer by the Holders of Certificates
evidencing not less than 25% of the Voting Rights evidenced by the Certificates;
or

                  (ii)   any failure by each Servicer to observe or perform in
any material respect any other of the covenants or agreements on the part of
each 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 each Servicer by the Securities Administrator or the
Depositor, or to the Securities Administrator by the Holders of Certificates
evidencing not less than 25% of the Voting Rights evidenced by the Certificates;
or

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

                  (iv)   consent by each Servicer to the appointment of a
receiver or liquidator in any insolvency, readjustment of debt, marshaling of
assets and liabilities or similar proceedings of or relating to each Servicer or
all or substantially all of the property of each Servicer; or

                  (v)    admission by a Servicer in writing of 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

                  (vi)   with respect to SLS only, an SLS Event of Termination
shall have occurred.

      If an Event of Default shall occur with respect to any Servicer, then, and
in each and every such case, so long as such Event of Default shall not have
been remedied within the applicable grace period, or solely with respect to
clause (i) above by 5:00 p.m. on each Servicer Remittance Date, the Securities
Administrator may, or at the direction of the Holders of Certificates evidencing
not less than 25% of the Voting Rights evidenced by the Certificates, shall, by
notice in writing to such Servicer (with a copy to each Rating Agency),
terminate all of the rights and obligations of such 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 such
Servicer of such written notice, all authority and power of such Servicer
hereunder, whether with respect to the Mortgage Loans or otherwise, shall pass
to and be vested

                                     -126-
<PAGE>

in the Securities Administrator. If an Event of Default described in clause (i)
hereof shall occur, the Trustee shall, by notice in writing to the Master
Servicer or a Servicer, and the Depositor, terminate all of the rights and
obligations of the Master Servicer or a Servicer, in its capacity as Master
Servicer or Servicer, as applicable, under this Agreement and in and to the
Mortgage Loans and the proceeds thereof. The Securities Administrator is hereby
authorized and empowered to execute and deliver, on behalf of each Servicer and
the Trustee, 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 each Servicer to pay
amounts owed pursuant to Article VIII. Each Servicer agrees to cooperate with
the Securities Administrator in effecting the termination of such Servicer's
responsibilities and rights hereunder, including, without limitation, the
transfer to the Securities Administrator of all cash amounts which shall at the
time be credited to the Collection Account, or thereafter be received with
respect to the Mortgage Loans. Each Servicer and the Securities Administrator
shall promptly notify the Rating Agencies of the occurrence of an Event of
Default or an event that, with notice, passage of time, other action or any
combination of the foregoing would be an Event of Default, such notice to be
provided in any event within two Business Days of such occurrence.

      Notwithstanding any termination of the activities of such Servicer
hereunder, such 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 Servicer's rights and obligations as Servicer hereunder
and received after such notice, that portion thereof to which such Servicer
would have been entitled pursuant to Sections 3.08(a)(i) through (viii), and any
other amounts payable to such Servicer hereunder the entitlement to which arose
prior to the termination of its activities hereunder. Notwithstanding anything
herein to the contrary, upon termination of such Servicer hereunder, any
liabilities of such Servicer which accrued prior to such termination shall
survive such termination.

      SECTION 8.02. Securities Administrator to Act; Master Servicer and Backup
Servicer to Act; Appointment of Successor.

            (a)   On and after the time the Master Servicer or any Servicer
receives a notice of termination, the Securities Administrator (in the case of
the Master Servicer), Master Servicer (in the case of Countrywide) or the Backup
Servicer (in the case of SLS) shall be the successor in all respects to the
Master Servicer or such Servicer, as applicable, in its capacity as master
servicer or servicer under this Agreement and the transactions set forth or
provided for herein, and all the responsibilities, duties and liabilities
relating thereto and arising thereafter shall be assumed by the Securities
Administrator (except for any representations or warranties of the Master
Servicer under this Agreement, the responsibilities, duties and liabilities
contained in Section 2.03) (in the case of the Master Servicer), the Master
Servicer (except for any representations or warranties of Countrywide contained
in Section 2.03) (in the case of Countrywide) or the Backup Servicer (except for
any representations and warranties of SLS contained in Section 2.03) (in the
case of SLS) by the terms and provisions hereof including, without limitation,
the Servicers' obligations to make Advances pursuant to Section 3.21 and subject
Section 3.08; provided, however, that if the Securities Administrator, Master
Servicer or Backup Servicer, as applicable, is prohibited by law or regulation
from obligating itself to make advances regarding delinquent mortgage loans,
then the Securities Administrator, Master Servicer or Backup Servicer, as
applicable, shall not be obligated to make Advances pursuant to Section 3.21;
and provided further, that any failure to perform such duties or
responsibilities caused by the Master Servicer's or any Servicer's failure to
provide information required by Section 9.01 shall not be considered a default
by the Securities Administrator (in the case of the Master Servicer), the Master
Servicer (in the case of Countrywide) or the Backup Servicer (in the case of
SLS) as successor to any Servicer hereunder. As compensation therefor, the
Master

                                     -127-
<PAGE>

Servicer (in the case of Countrywide) or the Backup Servicer (in the case of
SLS) shall be entitled to the Servicing Fee and all other compensation to which
the related Servicer would have been entitled if it had continued to act
hereunder and the Securities Administrator (in the case of the Master Servicer)
shall be entitled to all compensation to which the Master Servicer is entitled
hereunder. Nothing in this Section 8.02(a) shall require the Securities
Administrator to make an Advance with respect to any Mortgage Loan for which the
Master Servicer or any Servicer was not required to make such an advance.

            (b)   No appointment of a successor to the Master Servicer or any
Servicer under this Agreement shall be effective until the assumption by the
successor of all of the Master Servicer's or Servicer's, as applicable,
responsibilities, duties and liabilities hereunder. In connection with such
appointment and assumption described herein, the Securities Administrator, the
Master Servicer and the Backup Servicer may make such arrangements for the
compensation of such successor out of payments on Mortgage Loans as it and such
successor shall agree; provided, however, that no such compensation shall be in
excess of that permitted the Master Servicer or Servicer as such hereunder. The
Depositor, the Securities Administrator, the Master Servicer, the Trustee and
such successor shall take such action, consistent with this Agreement, as shall
be necessary to effectuate any such succession. Pending appointment of a
successor to the Master Servicer or any Servicer under this Agreement, the
Securities Administrator (in the case of the Master Servicer), Master Servicer
(in the case of Countrywide) or the Backup Servicer (in the case of SLS) shall
act in such capacity as hereinabove provided.

            (c)   (1) In the event of a SLS Event of Termination,
notwithstanding anything to the contrary above, the Trustee, the Master
Servicer, the Backup Servicer and the Depositor hereby agree that upon delivery
to the Trustee, the Securities Administrator, the Master Servicer and the Backup
Servicer by the Servicing Rights Pledgee of a letter signed by the Servicing
Rights Pledgee within 10 days of when the terminated Servicer provides the
Servicing Rights Pledgee notice of a SLS Event of Termination related to it, the
Servicing Rights Pledgee or its designee shall be appointed as successor
Servicer, provided that at the time of such appointment, the Servicing Rights
Pledgee or such designee meets the requirements of a successor Servicer set
forth in paragraph (c)(2) below and the Servicing Rights Pledgee or such
designee agrees to be subject to the terms of this Agreement.

      (2)   In the event that the Servicing Rights Pledgee does not deliver to
the Trustee, the Securities Administrator, the Master Servicer and the Backup
Servicer the letter described in preceding paragraph within the 10-day period
referred to in the preceding paragraph, the Master Servicer (in the case of
Countrywide) or the Backup Servicer (in the case of SLS) shall be the successor
in all respects to the related Servicer in its capacity as Servicer under this
Agreement and the transactions set forth or provided for herein, and all the
responsibilities, duties and liabilities relating thereto and arising thereafter
shall be assumed by the Master Servicer (except for any representations or
warranties of Countrywide contained in Section 2.03) (in the case of
Countrywide) or the Backup Servicer (except for any representations and
warranties of SLS contained in Section 2.03) (in the case of Countrywide) by the
terms and provisions hereof including, without limitation, the Servicer's
obligations to make Advances pursuant to Section 3.21.

      (3)   It is understood and acknowledged by the parties hereto that (a)
there will be a period of transition (not to exceed 90 days when servicing is
being transferred to the Master Servicer or a successor servicer and not to
exceed 30 days when servicing is being transferred to the Backup Servicer)
before the actual servicing functions can be fully transferred to any successor
Master Servicer or Servicer appointed in accordance with the provisions hereof
and (b) any failure to perform such duties or responsibilities caused by the
Master Servicer's or any Servicer's, as applicable, failure to provide
information required by Section 9.01 shall not be considered a default by the
Securities Administrator (in the case of the Master Servicer), the Master
Servicer (in the case of Countrywide) or the Backup Servicer (in the case of
SLS) as successor to the Master Servicer or any Servicer, as applicable,
hereunder. Notwithstanding the above and subject to the immediately following
paragraph, the Securities Administrator, the Master

                                     -128-
<PAGE>

Servicer or the Backup Servicer, as applicable, may, if it shall be unwilling to
so act, or shall, if it is unable to so act promptly appoint or petition a court
of competent jurisdiction to appoint, an established mortgage loan servicing
institution acceptable to each Rating Agency and having a net worth of not less
than $15,000,000, as the successor to the related Servicer under this Agreement
in the assumption of all or any part of the responsibilities, duties or
liabilities of the related Servicer under this Agreement.

      Notwithstanding anything to the contrary herein, any successor Master
Servicer or Servicer appointed pursuant to this Section 8.02(c)(2) shall agree
to fully effect the servicing transfer within the 90-day or 30-day period
referred to in Section 8.02(c)(2) above and to make all Advances that would
otherwise be made by another party under Section 8.01 as of the date of such
appointment. Each successor Master Servicer and Servicer shall be entitled to
reimbursement for any unreimbursed Advances it has made in connection with this
Section 8.02 pursuant to Section 3.08. In addition, any successor to the related
Servicer shall give notice to the Mortgagors of such change of Servicer and
shall, during the term of its service as a Servicer, maintain in force the
policy or policies that each Servicer is required to maintain pursuant to this
Agreement.

            (d)   In connection with the termination or resignation of any
Servicer hereunder, (i) the successor Servicer, including the Master Servicer or
Backup Servicer, as applicable, shall represent and warrant that it or an
Affiliate 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, in which case the
predecessor Servicer shall cooperate with the successor Servicer in causing MERS
to revise its records to reflect the transfer of servicing to the successor
Servicer as necessary under MERS' rules and regulations, and (ii) the
predecessor Servicer shall cooperate with the successor Servicer in causing MERS
to transfer the servicing of such Mortgage Loan on the MERS(R) System to the
successor Servicer. The predecessor Servicer shall file or cause to be filed any
such assignment in the appropriate recording office. The predecessor Servicer,
as applicable, shall bear any and all fees of MERS, costs of preparing any
assignments of Mortgage, and fees and costs of filing any assignments of
Mortgage that may be required under this Section 8.02.

      SECTION 8.03. Notification to Certificateholders.

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

            (b)   Within 60 days after the occurrence of any Event of Default of
which a Responsible Officer of the Securities Administrator has actual
knowledge, the Securities Administrator shall transmit by mail to all
Certificateholders and the Trustee notice of each such Event of Default
hereunder known to the Securities Administrator, unless such Event of Default
shall have been cured or waived.

      SECTION 8.04. Waiver of Servicer Events of Default.

      The Holders representing at least 66 2/3% of the Voting Rights evidenced
by all Classes of Certificates affected by any SLS Event of Termination
hereunder may waive such SLS Event of Termination; provided, however, that a SLS
Event of Termination under clause (i) or (vi) of Section 8.01 may be waived only
by all of the Holders of the Regular Certificates. Upon any such waiver of an
Event of Default, such Event of Default shall cease to exist and shall be deemed
to have been remedied for every purpose hereunder. No such waiver shall extend
to any subsequent Event of Default or impair any right consequent thereon except
to the extent expressly so waived.

                                     -129-

      SECTION 8.05. SLS Events of Default.

            (a)   "SLS Event of Termination," wherever used herein, means any
one of the following events:

                  (i)    any failure by SLS to provide the monthly data tape to
the Backup Servicer, which failure continues for three Business Days after the
date such action is required hereunder;

                  (ii)   SLS fails to make the Advance required pursuant to
Section 5.01 of this Agreement and such failure continues for two Business Days
after the date such action is required hereunder;

                  (iii)  an SLS Financial Trigger Event occurs and is
continuing;

                  (iv)   as of any Determination Date, the Rolling Three Month
Delinquency Rate exceeds 15% and the Rating Agencies do not confirm the ratings
of the Certificates within ten (10) Business Days of such date; or

                  (v)    an SLS Cross Default occurs.

                                   ARTICLE IX

             CONCERNING THE TRUSTEE AND THE SECURITIES ADMINISTRATOR

      SECTION 9.01. Duties of the Trustee.

            (a)   The Trustee undertakes to perform such duties and only such
duties as are specifically set forth in this Agreement as duties of the Trustee.
During the continuance of an Event of Default, 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 its exercise as a prudent person would exercise or use
under the circumstances in the conduct of such person's own affairs. Any
permissive right of the Trustee enumerated in this Agreement shall not be
construed as a duty.

            (b)   The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to it, which 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. If any such instrument is found not to conform
to the requirements of this Agreement in a material manner, the Trustee shall
take such action as it deems appropriate to have the instrument corrected, and
if the instrument is not corrected to its satisfaction, the Trustee will provide
notice to the Certificateholders. Notwithstanding the foregoing, the Trustee
shall have no obligation to reconcile, recompute or recalculate any remittances
or reports of any Servicer or the Interim Servicer, and the Trustee may fully
rely upon and shall have no liability with respect to information provided by
any Servicer or the Interim Servicer.

            (c)   The Trustee shall promptly remit to the related Servicer any
complaint, claim, demand, notice or other document (collectively, the "Notices")
delivered to the Trustee as a consequence of the assignment of any Mortgage Loan
hereunder and relating to the servicing of the Mortgage Loans; provided than any
such notice (i) is delivered to the Trustee at is Corporate Trust Office, and
(ii) contains information sufficient to permit the Trustee to make a
determination that the real property to which such document relates is a
Mortgaged Property. The Trustee shall have no duty hereunder with respect to any
Notice it may receive or which may be alleged to have been delivered to or
served upon it unless such

                                     -130-
<PAGE>

Notice is delivered to it or served upon it at its Corporate Trust Office and
such Notice contains the information required pursuant to clause (ii) of the
preceding sentence.

            (d)   No provision of this Agreement shall be construed to relieve
the Trustee from liability for its own negligent action, its own negligent
failure to act or its own willful misconduct; provided, however, that:

                  (i)    The duties and obligations of the Trustee shall be
determined solely by the express provisions of this Agreement; the Trustee shall
not be liable 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, in the absence of bad
faith on the part of the Trustee, 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 that conform to the
requirements of this Agreement;

                  (ii)   The Trustee shall not be liable for an error of
judgment made in good faith by a Responsible Officer of the Trustee unless it
shall be proved that the Trustee was negligent in ascertaining or investigating
the facts related thereto;

                  (iii)  The Trustee shall not be personally liable with respect
to any action taken, suffered or omitted to be taken by it in good faith in
accordance with the consent or at the direction of Holders of Certificates as
provided herein relating to the time, method and place of conducting any remedy
pursuant to this Agreement, or exercising or omitting to exercise any trust or
power conferred upon the Trustee under this Agreement; and

                  (iv)   The Trustee shall not be required to expend or risk its
own funds or otherwise incur financial or other liability in the performance of
any of its duties hereunder, or in the exercise of any of its rights or powers,
if there is reasonable ground for believing that the repayment of such funds or
indemnity satisfactory to it against such risk or liability is not assured to
it, and none of the provisions contained in this Agreement shall in any event
require the Trustee to perform, or be responsible for the manner of performance
of, any of the obligations of any Servicer under this Agreement, except during
such time, if any, as the Trustee shall be the successor to, and be vested with
the rights, duties, powers and privileges of, the Master Servicer in accordance
with the terms of this Agreement.

                  (v)    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 in accordance with
this Agreement 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.

      SECTION 9.02. Certain Matters Affecting the Trustee.

            (a)   Except as otherwise provided in Section 9.01:

                  (i)    The Trustee may request and conclusively rely upon, and
shall be fully 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 reasonably believed by it to
be genuine and to have been signed or presented by the proper party or parties,
and the manner of obtaining consents and of evidencing the authorization of the
execution thereof by Certificateholders shall be subject to such reasonable
regulations as the Trustee may prescribe;

                                     -131-
<PAGE>

                  (ii)   The Trustee may consult with counsel of its selection
and any advice of such counsel or 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 advice or
Opinion of Counsel;

                  (iii)  The Trustee shall not be under any obligation to
exercise any of the trusts or powers vested in it by this Agreement 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 satisfactory to it
against the costs, expenses and liabilities which may be incurred therein or
thereby;

                  (iv)   The Trustee shall not be personally liable 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;

                  (v)    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 to do so by the Holders of
Certificates entitled to at least 25% of the Voting Rights; 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
satisfactory to it against such expense, or liability from such
Certificateholders as a condition to taking any such action;

                  (vi)   The Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents, nominees, attorneys or a custodian, and shall not be responsible for any
misconduct or negligence on the part of any agent, nominee, attorney or
custodian appointed by the Trustee in good faith; and


                  (vii) The Trustee shall not be liable for any loss on any

knowledge thereof or unless written notice of any event which is in fact such a
default is received by the Trustee at the Corporate Trust Office of the Trustee,
and such notice references the Certificates and this Agreement. The Trustee
shall not have any responsibility or liability for any action or failure to act
by the Master Servicer, Backup Servicer, any Servicer or the Interim Servicer
nor shall the Trustee be obligated to supervise or monitor the performance of
the Master Servicer, Backup Servicer, any Servicer or the Interim Servicer
hereunder or otherwise;

appointment of the Custodian to act as custodian pursuant to the Custodial
Agreement and each further agree that the Trustee appointed the Custodian to act
as custodian with due care

                  (xii)  if requested by each Servicer, the Trustee may appoint
each Servicer as the trustee's attorney-in-fact in order to carry out and
perform certain activities that are necessary or appropriate for the servicing
and administration of the Mortgage Loans pursuant to this Agreement. Such
appointment shall be evidenced by a power of attorney in such form as may be
agreed to by the Trustee and each Servicer. The Trustee shall have no liability
for any action or inaction of each Servicer in connection with such power of
attorney and the Trustee shall be indemnified by each Servicer for all
liabilities, costs and expenses incurred by the Trustee in connection with each
Servicer's use or misuse of such powers of attorney; and

            (b)   All rights of action under this Agreement or under any of the
Certificates, enforceable by the Trustee, may be enforced by it without the

instituted by the Trustee shall be brought in its name for the benefit of all
the Holders of such Certificates, subject to the provisions of this Agreement.

            (c)   Notwithstanding anything in this Agreement to the contrary, in
no event shall the Trustee be liable to any Person for any act or omission of
the Master Servicer, the Backup Servicer, any Servicer or the Interim Servicer.

      SECTION 9.03. The Trustee Not Liable for Certificates or Mortgage Loans.

      The recitals contained herein and in the Certificates (other than the
authentication and countersignature on the Certificates) shall be taken as the
statements of the Seller, and neither the Trustee nor the Certificate Registrar

make any representations or warranties as to the validity or sufficiency of this
Agreement, the Interim Servicing Agreement, the Custodial Agreement or of the
Certificates (other than the signature and countersignature on the Certificates)
or of any Mortgage Loan or related document or of MERS or the MERS System. The
Trustee shall not be accountable for the use or application by the Depositor of
any of the Certificates or of the proceeds of such Certificates, or for the use
or application of any funds paid to the Depositor in respect of the Mortgage
Loans or deposited in or withdrawn from the Collection Account by any Servicer.
The Trustee shall not have any duty (a) to see to any recording, filing or
depositing of this Agreement or any agreement referred to herein or any
financing statement or continuation statement evidencing a security interest, or
to see to the maintenance of any such recording, filing or depositing thereof,
(b) to see to any insurance or (c) to see to the payment or discharge of any
tax, assessment or other governmental charge or any lien or encumbrance of any
kind owing with respect to, assessed or levied against, any part of the Trust.

      SECTION 9.04. The Trustee May Own Certificates.

      The Trustee, in its individual capacity, or in any capacity other than as

rights as it would have if it was not the Trustee, and may otherwise deal with
the parties hereto.

      SECTION 9.05. Trustee's Fees and Expenses.

paid to the Securities Administrator by the Master Servicer pursuant to an

recover from the Certificate Account, and shall be indemnified from the Trust
Fund for, all reasonable out-of-pocket expenses, disbursements and advances upon
any Event of Default, any breach of this Agreement, the Custodial Agreement or
the Interim Servicing Agreement or any loss, liability, expense, claim or legal
action (including any pending or threatened claim or legal action) incurred or
made by any of them in the performance of their duties or the administration of
the trusts hereunder or under the Custodial Agreement (including the reasonable
compensation, expenses and disbursements of its counsel) except any such
expense, loss, liability, disbursement or advance (i) as may arise from its
negligence or intentional misconduct or (ii) that does not constitute an
"unanticipated expense" within the meaning of Treasury Regulations Section
1.860G-1(b)(3)(ii). If funds in the Certificate Account are insufficient
therefor, the Trustee shall recover such expenses from future collections on the
Mortgage Loans or as otherwise agreed by the Certificateholders. Such
compensation and reimbursement obligation shall not be limited by any provision
of law in regard to the compensation of a trustee of an express trust. Such
obligations shall survive the termination of this Agreement and the removal or
resignation of the Trustee.

      SECTION 9.06. [RESERVED].

      SECTION 9.07. Eligibility Requirements for the Trustee.

      The Trustee hereunder shall at all times be an entity duly organized and
validly existing under the laws of the United States of America or any state
thereof, authorized under such laws to exercise corporate trust powers, and
shall each have a combined capital and surplus of at least $50,000,000, a
minimum long-term debt rating in the third highest rating category by a Rating
Agency, a minimum short-term debt rating in the second highest rating category
by a Rating Agency, and shall each be subject to supervision or examination by
federal or state authority. If such entity 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 9.07,
the combined capital and surplus of such entity shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. The principal office of the Trustee (other than the initial
Trustee) shall be in a state with respect to which an Opinion of Counsel has
been delivered to such Trustee at the time such Trustee is appointed Trustee to
the effect that the Trust will not be a taxable entity under the laws of such
state. In case at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 9.07, the Trustee shall resign immediately
in the manner and with the effect specified in Section 9.08 hereof.

      SECTION 9.08. Resignation and Removal of the Trustee.

      The Trustee may at any time resign and be discharged from the trust hereby
created by giving written notice thereof to the Depositor, the Seller, the
Master Servicer, the Backup Servicer, each Servicer and the Rating Agency. Upon
receiving such notice of resignation of the Trustee, the Depositor shall
promptly appoint a successor Trustee that meets the requirements in Section
9.07, by written instrument, in duplicate, one copy of which instrument shall be
delivered to each of the resigning Trustee and one copy to the successor
Trustee. If no successor Trustee shall have been so appointed and having
accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

      If at any time the Trustee shall cease to be eligible in accordance with
the provisions of Section 9.07 hereof or if at any time the Trustee shall be
legally unable to act, or shall be adjudged a 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, then the
Depositor may remove the Trustee. If the Depositor removes the Trustee under the
authority of the immediately preceding sentence, the Depositor shall promptly
appoint a successor Trustee that meets the requirements of Section 9.07, by
written instrument, in duplicate, one copy of

                                     -134-
<PAGE>

which instrument shall be delivered to the successor Trustee and one copy to
each of the Master Servicer, the Backup Servicer and each Servicer.

      The Holders of Certificates entitled to at least 51% of the Voting Rights
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 to the Depositor, one complete set to the Trustee so removed and
one complete set to the successor so appointed. A copy of such instrument shall
be delivered to the Certificateholders, the Trustee and the Master Servicer, the
Backup Servicer and each Servicer by the Depositor.

      Any resignation or removal of the Trustee and appointment of a successor
Trustee pursuant to any of the provisions of this Section 9.08 shall not become
effective until acceptance of appointment by the successor Trustee, as provided
in Section 9.10 hereof.

      SECTION 9.09. [RESERVED].

      SECTION 9.10. Successor Trustee.

      Any successor Trustee appointed as provided in Section 9.08 hereof shall
execute, acknowledge and deliver to the Depositor, the Seller, each Servicer,
the Backup Servicer, the Master Servicer and to its predecessor Trustee 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 like effect as if originally named as Trustee. The Depositor,
the Seller, each Servicer, the Backup Servicer, the Master Servicer and the
predecessor Trustee shall execute and deliver such instruments and do such other
things as may reasonably be required for fully and certainly vesting and
confirming in the successor Trustee, all such rights, powers, duties and
obligations.

      No successor Trustee shall accept appointment as provided in this Section
9.10 unless at the time of such acceptance such successor Trustee shall be
eligible under the provisions of Section 9.07 hereof and the appointment of such
successor Trustee shall not result in a downgrading of the Classes of
Certificates rated by the Rating Agencies, as evidenced by a letter from each
Rating Agency.

      Upon acceptance of appointment by a successor Trustee as provided in this
Section 9.10, the successor Trustee shall mail notice of such appointment
hereunder to all Holders of Certificates at their addresses as shown in the
Certificate Register and to the Rating Agencies.

      SECTION 9.11. Merger or Consolidation of the Trustee.

      Any corporation or association into which the Trustee may be merged or
converted or with which it may be consolidated or any corporation or association
resulting from any merger, conversion or consolidation to which the Trustee
shall be a party, or any corporation or association succeeding to the business
of the Trustee shall be the successor of the Trustee hereunder, provided such
corporation or association shall be eligible under the provisions of Section
9.07, 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.

      SECTION 9.12. 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 Depositor and the Trustee acting jointly shall have the

                                     -135-
<PAGE>

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 9.12, such powers, duties, obligations, rights and trusts as the
Depositor and the Trustee may consider necessary or desirable. If the Depositor
shall not have joined in such appointment within 15 days after the 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 9.07 and no
notice to Certificateholders of the appointment of any co-trustee or separate
trustee shall be required under Section 9.10.

      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)    To the extent necessary to effectuate the purposes of
this Section 9.12, all rights, powers, duties and obligations conferred or
imposed upon the Trustee, except for the obligation of the Trustee in its
capacity as successor servicer under this Agreement to advance funds on behalf
of a 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 set or acts are to be performed
(whether as Trustee hereunder or as successor to the Master Servicer, Backup
Servicer or any other 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;

                  (ii)   No trustee hereunder shall be held personally liable by
reason of any act or omission of any other trustee hereunder and such
appointment shall not, and shall not be deemed to, constitute any such separate
trustee or co-trustee as agent of the Trustee;

                  (iii)  The Trustee may at any time accept the resignation of
or remove any separate trustee or co-trustee; and

                  (iv)   The Depositor, and not the Trustee, shall be liable for
the payment of reasonable compensation, reimbursement and indemnification to any
such 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 separate trustees and co-trustees, when and 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 IX. 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
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

                                     -136-
<PAGE>

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.

            (a)   It is intended that each of the REMICs provided for herein

conducted so as to allow each such REMIC to qualify as, a "real estate mortgage
investment conduit" as defined in and in accordance with the REMIC Provisions.
It is also intended that each of the grantor trusts provided for in Section 2.07
hereof shall constitute, and that the affairs of the Trust Fund shall be

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 of
the REMICs and grantor trusts provided for herein, containing such information

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 SS-4 or as otherwise may be required by the Code, the name, title,

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 each of the REMICs provided
for herein; (c) make or cause to be made elections, on behalf of each of the
REMICs provided for herein to be treated as a REMIC on the federal tax return of
such REMICs for their first taxable years (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 or other
applicable tax law or with respect to the grantor trusts provided for herein,
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 R Certificate to a Person
that is not a Permitted Transferee, or an agent (including a broker, nominee or
other middleman) of a Person that is not a Permitted Transferee, or a
pass-through entity in which a Person that is not a 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 each of the REMICs
and grantor trusts provided for herein at all times that any Certificates are
outstanding so as to maintain the status of each of the REMICs provided for
herein as a REMIC under the REMIC Provisions and the status of each of the
grantor trusts provided for herein as a grantor trust under Subpart E, Part I of
subchapter J of the Code; (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 of the REMICs provided for herein or result in the imposition of tax upon
any such REMIC; (h) not knowingly or intentionally take any action or omit to
take any action that would cause the termination of the grantor trust status
under Subpart E, Part I of Subchapter J of the Code of any of the grantor trusts
provided to herein or result in the imposition of tax upon any such grantor
trusts; (i) pay, from the sources specified in the last paragraph of this
Section 9.13(a), the amount of any federal, state and local taxes, including
prohibited transaction taxes as described below, imposed on each of the REMICs
or grantor trusts provided for herein prior to the

                                     -137-
<PAGE>

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 Securities Administrator from withholding payment of such tax, if permitted
by law, pending the outcome of such proceedings); (j) sign or cause to be signed
by the required person federal, state or local income tax or information
returns; (k) maintain records relating to each of the REMICs and grantor trusts
provided for herein, including but not limited to the income, expenses, assets
and liabilities of each of the REMICs and grantor trusts provided for herein,
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, in each
instance, to the extent provided by each Servicer; and (l) as and when necessary
and appropriate, represent each of the REMICs and grantor trusts provided for
herein 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 of the REMICs provided for herein,
enter into settlement agreements with any governmental taxing agency, extend any
statute of limitations relating to any tax item of any of the REMICs provided
for herein, and otherwise act on behalf of each of the REMICs and grantor trusts
provided for herein in relation to any tax matter involving any of such REMICs
or any controversy involving the Trust Fund. The Trustee agrees to sign such tax
returns prepared by the Securities Administrator pursuant to this Agreement as
may be required by applicable law.

      In order to enable the Securities Administrator to perform its duties as
set forth herein, the Depositor shall provide, or cause to be provided, to the
Securities Administrator within 10 days after the Closing Date all information
or data that the Securities Administrator 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.
Thereafter, the Depositor shall provide to the Securities Administrator promptly
upon written request therefor, any such additional information or data that the
Securities Administrator may, from time to time, request in order to enable the
Securities Administrator to perform its duties as set forth herein. The
Depositor hereby agrees to indemnify the Securities Administrator for any
losses, liabilities, damages, claims or expenses of the Securities Administrator
arising from any errors or miscalculations of the Securities Administrator that
result from any failure of the Depositor to provide, or to cause to be provided,
accurate information or data to the Securities Administrator on a timely basis.

      In the event that any tax is imposed on "prohibited transactions" of any
of the REMICs provided for herein as defined in Section 860F(a)(2) of the Code,
on the "net income from foreclosure property" of the any of such REMICs 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, 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 or as a result of
the location of the Trustee, (ii) 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 as a result of the
location of such other party 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 R Certificateholder pursuant to Section 5.05, and
second with amounts (other than amounts derived by the Trust Fund from a payment
on the Cap Contract) otherwise to be distributed to all other Certificateholders
in the following order of priority: first, to the Class N Certificates (pro
rata), second to the Class X Certificates (pro rata), third, to the Class B-3
Certificates (pro rata), fourth, to the Class B-2 Certificates (pro rata),
fifth, to the Class B-1 Certificates (pro rata), sixth, to the Class M-3
Certificates (pro rata), seventh, to the Class M-2 Certificates (pro rata),
eighth, to the Class M-1 Certificates and ninth to the Class A Certificates (pro
rata). Notwithstanding anything to the contrary contained herein, to the extent
that such tax is payable by the Class R Certificate,

                                     -138-
<PAGE>

the Trustee is hereby authorized pursuant to such instruction to retain on any
Distribution Date, from the Holder of the Class R Certificate (and, if
necessary, from the Holders of 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.

      (b)   Each of the Depositor, the Securities Administrator and the Trustee
agrees not to knowingly or intentionally take any action or omit to take any
action that would (i) cause the termination of the REMIC status of any of the
REMICs provided for herein or result in the imposition of a tax upon any of the
REMICs provided for herein or (ii) cause the termination of the grantor trust
status of any of the grantor trusts provided for herein or result in the
imposition of a tax upon any of the grantor trusts provided for herein.

      (c)   In the event that the beneficial ownership of the Class N and Class
X Certificates is held by a single Person for federal income tax purposes or by
multiple Persons who beneficially own the Class N and Class X Certificates
proportionately, such Person or Persons shall be treated as the direct or
indirect beneficial owner of the REMIC 4 XN, the Cap Contract, the Cap Contract
Account and the right to Prepayment Penalties, amounts paid by the Servicer, the
Seller or any Transferor in respect of Prepayment Penalties pursuant to this
Agreement or a Transfer Agreement, as applicable and amounts received in respect
of any indemnification paid as a result of a Prepayment Penalty being
unenforceable in breach of the representations and warranties set forth in a
Transfer Agreement. In the event that the Trustee and the Securities
Administrator receive written notice that the beneficial ownership of the Class
N and the Class X Certificates is held by two or more Persons for federal income
tax purposes that do not beneficially own the Class N and Class X Certificates
proportionately, the Trustee shall treat the Class N Certificateholders and the
Class X Certificateholders as partners in a partnership that owns the REMIC 4 XN
Interest, the Cap Contract, the Cap Contract Account and the right to Prepayment
Penalties, amounts paid by the Servicer, the Seller or any Transferor in respect
of Prepayment Penalties pursuant to this Agreement or a Transfer Agreement, as
applicable and amounts received in respect of any indemnification paid as a
result of a Prepayment Penalty being unenforceable in breach of the
representations and warranties set forth in a Transfer Agreement, and shall not
treat the Class N and Class X Certificates as a direct interest in any REMIC
hereunder. By acquiring the Class N and the Class X Certificates, the respective
Holders will agree to treat the Class N and Class X Certificates in the manner
described in the preceding sentences for federal income tax purposes in the
event that the beneficial ownership of the Class N Certificates and the Class X
Certificates is separated. In such event, (i) a separate capital account shall
be established and maintained for each Holder of a Class N or Class X
Certificate in accordance with Treasury Regulations Section 1.704-1(b)(2)(iv),
which shall be credited with income or gain and debited by any expenses
(including any payments deemed made to the Holders of any of the Class A, Class
M-1, Class M-2, Class M-3, Class B or Class R Certificates on interest rate cap
agreements for federal income tax purposes) or losses or distributions allocable
to the assets deemed held by such partnership, (ii) the Class N Certificates
shall be allocated income in an amount equal to interest at the Class N Interest
Rate and any original issue discount that would be reportable thereon if the
Class N Certificate were a debt instrument issued on the date ownership of the
Class N and Class X Certificates is separated, with a principal balance equal to
the Class N Notional Balance, (iii) the Class X and Class N Certificates shall
be allocated income with respect to all Prepayment Penalties, amounts paid by
the Servicer, the Seller or any Transferor in respect of Prepayment Penalties
pursuant to this Agreement or a Transfer Agreement, as applicable and amounts
received in respect of any indemnification paid as a result of a Prepayment
Penalty being unenforceable in breach of the representations and warranties set
forth in a Transfer Agreement, in accordance with the allocation of such amounts
pursuant to Section 5.05(i), to the extent not allocated under Section
9.13(c)(ii) above, (iv) the Class X and Class N Certificates shall be allocated
accruals (under any reasonable method) of any "cap premiums" deemed received on
the date ownership of the Class X and Class N Certificates is

                                     -139-
<PAGE>

separated in respect of the obligation of the REMIC 4 XN Interest to pay amounts
of Excess Interest under Section 2.07, and shall be allocated expense in respect
of any actual payment of such Excess Interest based on which one of such Classes
economically bears such expense, (v) the Class X Certificates shall be allocated

obligations shall survive the termination of this Agreement and the removal or
resignation of the Securities Administrator.

purposes of this Section 9.19, the combined capital and surplus of such entity
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. The principal office of the Securities
Administrator (other than the initial Securities Administrator) shall be in a

entity under the laws of such state. In case at any time the Securities
Administrator shall cease to be eligible in accordance with the provisions of
this Section 9.19, the Securities Administrator shall resign immediately in the
manner and with the effect specified in Section 9.20 hereof.

      SECTION 9.20. Resignation and Removal of the Securities Administrator.

and the Rating Agency. Upon receiving such notice of resignation of the
Securities Administrator, the Depositor shall promptly appoint a successor
Securities Administrator that meets the requirements in Section 9.19, by written
instrument, in duplicate, one copy of which instrument shall be delivered to

accordance with the provisions of Section 9.19 hereof or if at any time the
Securities Administrator shall be legally unable to act, or shall be adjudged a
bankrupt or insolvent, or a receiver of the Securities Administrator or of its
property shall be appointed, or any public officer shall take charge or control
of the Securities Administrator or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, then the Depositor may remove the
Securities Administrator. If the Depositor removes the Securities Administrator
under the authority of the immediately preceding sentence, the Depositor shall
promptly appoint a successor Securities Administrator that meets the
requirements of Section 9.19, by written instrument, in duplicate, one copy of
which instrument shall be delivered to the successor Securities Administrator
and one copy to each of the Master Servicer, the Backup Servicer and each
Servicer.

      The Holders of Certificates entitled to at least 51% of the Voting Rights

Securities Administrator by written instrument or instruments, in triplicate,

the Master Servicer, the Backup Servicer and each Servicer by the Depositor.

      Any resignation or removal of the Securities Administrator and appointment
of a successor Securities Administrator pursuant to any of the provisions of
this Section 9.20 shall not become effective until acceptance of appointment by
the successor Securities Administrator, as provided in Section 9.21 hereof.

      SECTION 9.21. Successor Securities Administrator.

      Any successor Securities Administrator appointed as provided in Section
9.20 hereof shall execute, acknowledge and deliver to the Depositor, the Seller,
each Servicer, the Backup Servicer, the Master Servicer and to its predecessor
Securities Administrator an instrument accepting such appointment hereunder, and
thereupon the resignation or removal of the predecessor Securities Administrator
shall become effective, and such successor Securities Administrator without any
further act, deed or conveyance, shall become fully vested with all the rights,
powers, duties and obligations of its predecessor hereunder, with like effect as
if originally named as Securities Administrator. The Depositor, the Seller, each
Servicer, the Backup Servicer, the Master Servicer and the predecessor
Securities Administrator shall execute and deliver such instruments and do such
other things as may reasonably be required for fully and certainly vesting and
confirming in the successor Securities Administrator, all such rights, powers,
duties and obligations.

      No successor Securities Administrator shall accept appointment as provided
in this Section 9.21 unless at the time of such acceptance such successor
Securities Administrator shall be eligible under the provisions of Section 9.19
hereof and the appointment of such successor Securities Administrator shall not
result in a downgrading of the Classes of Certificates rated by the Rating
Agencies, as evidenced by a letter from each Rating Agency.

      Upon acceptance of appointment by a successor Securities Administrator as
provided in this Section 9.21, the successor Securities Administrator shall mail
notice of such appointment hereunder to all Holders of Certificates at their
addresses as shown in the Certificate Register and to the Rating Agencies.

      SECTION 9.22. Merger or Consolidation of Securities Administrator.

      Any corporation or association into which the Securities Administrator may
be merged or converted or with which it may be consolidated or any corporation
or association resulting from any merger, conversion or consolidation to which
the Securities Administrator shall be a party, or any corporation or association
succeeding to the business of the Securities Administrator shall be the
successor of the Securities Administrator hereunder, provided such corporation
or association shall be eligible under the provisions of Section 9.19, 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.

the Trustee created hereby with respect to the

                                     -145-
<PAGE>

Trust Fund shall terminate upon the earlier of (a) the exercise by Countrywide
of an Optional Termination; 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.

      Any termination pursuant to clause (a) above shall be effected by
Countrywide purchasing all Mortgage Loans and REO Properties at a price equal to
the Optional Termination Price. Notwithstanding anything to the contrary herein,
the Optional Termination Amount paid by Countrywide shall be deposited by the
Securities Administrator directly into the Certificate Account immediately upon
Optional Termination.

      The right of Countrywide to effect an Optional Termination pursuant to
clause (a) above shall be conditioned upon (i) the consent of the holders of the
majority interest in the Class X Certificates and (ii) the aggregate Stated
Principal Balance of the Mortgage Loans, at the time of any such repurchase,
aggregating ten (10) percent or less of the sum of (x) the aggregate Stated
Principal Balance of the Mortgage Loans as of the Cut-off Date and (y) the
Original Pre-Funded Amount.

      SECTION 10.02. Final Distribution on the Certificates.

      If on any Determination Date, (i) the Securities Administrator determines
that there are no Outstanding Mortgage Loans and no other funds or assets in the
Trust Fund other than the funds in the Collection Account, the Securities
Administrator shall send a final distribution notice promptly to each
Certificateholder or (ii) the Securities Administrator determines that a Class
of Certificates shall be retired after a final distribution on such Class, the
Securities Administrator shall notify the Certificateholders within seven (7)
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 Certificates at the office of the Securities Administrator
specified in such notice. If each Servicer elects to terminate the Trust Fund
pursuant to clause (a) of Section 10.01, at least 10 days prior to the date
notice is to be mailed to the affected Certificateholders, the Securities
Administrator shall notify the Depositor and the Trustee of the date such
electing party intends to terminate the Trust Fund and of the applicable
repurchase price of the Mortgage Loans and REO Properties.

      Notice of any termination of the Trust Fund, specifying the Distribution
Date on which Certificateholders may surrender their Certificates for payment of
the final distribution and cancellation, shall be given promptly by the
Securities Administrator by letter to 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 the Certificates will be made
upon presentation and surrender of Certificates at the office therein
designated, (b) the location of the office or agency at which such presentation
and surrender must be made, and (c) that the Record Date otherwise applicable to
such Distribution Date is not applicable, distributions being made only upon
presentation and surrender of the Certificates at the office therein specified.
The Securities Administrator will give such notice to each Rating Agency at the
time such notice is given to Certificateholders.

                                     -146-
<PAGE>

      In the event such notice is given, the Securities Administrator shall
cause all funds in the Collection Account to be deposited in the Certificate
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 with respect to the Trust Fund, certification to the Trustee that
such required amount has been deposited in the Trust Fund and the receipt by the
Trustee of a Request for Release therefor, the Trustee shall promptly release to
the Mortgage Files for the Mortgage Loans.

      Upon presentation and surrender of the Certificates, the Securities
Administrator shall cause to be distributed to Certificateholders of each Class
the amounts allocable to such Certificates held in the Certificate Account in
the order and priority set forth in Section 5.05 hereof on the final
Distribution Date and in proportion to their respective Percentage Interests.

      In the event that any affected Certificateholders shall not surrender
Certificates for cancellation within six months after the date specified in the
above mentioned written notice, the Securities Administrator shall give a second
written notice to the remaining Certificateholders to surrender their
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 Securities
Administrator 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 Certificates shall not have been surrendered for
cancellation, the Class R Certificateholders shall be entitled to all unclaimed
funds and other assets of the Trust Fund that remain subject hereto. Upon
payment to the Class R Certificateholders of such funds and assets, neither the
Securities Administrator nor the Trustee shall have any further duties or
obligations with respect thereto.

      SECTION 10.03. Additional Termination Requirements.

            (a)   In the event Countrywide exercises its option to effect an
Optional Termination as provided in Section 10.01, 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
Countrywide 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 any of the REMICs provided for herein as defined
in section 860F of the Code, or (ii) cause any of the REMICs provided for herein
to fail to qualify as a REMIC at any time that any Certificates are outstanding:

                  (i)    The Depositor shall establish a 90-day liquidation
period and notify the Trustee and the Securities Administrator thereof, which
shall in turn specify the first day of such period in a statement attached to
the final tax returns of each of the REMICs provided for herein pursuant to
Treasury Regulation Section 1.860F-1. The Depositor shall 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 obtained at the
expense of each Servicer;

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

                  (iii)  At the time of the making of the final payment on the
Certificates, the Securities Administrator shall distribute or credit, or cause
to be distributed or credited, to the Class R Certificateholders all cash on
hand (other than cash retained to meet outstanding claims), and the Trust Fund
shall terminate at that time, whereupon neither the Securities Administrator nor
the Trustee shall

                                     -147-
<PAGE>

have any further duties or obligations with respect to sums distributed or
credited to the Class R Certificateholders.

            (b)   By their acceptance of the Certificates, the Holders thereof
hereby authorize the Depositor to specify the 90-day liquidation period for the
Trust Fund, which authorization shall be binding upon all successor
Certificateholders.

            (c)   The Trustee as agent for each REMIC hereby agrees to adopt and
sign such a plan of complete liquidation prepared and delivered to it by
Depositor upon the written request of the Depositor, and the receipt of the
Opinion of Counsel referred to in Section 9.03(a) and to take such other action
in connection therewith as may be reasonably requested by the Depositor.

                  (i)    to cure any ambiguity or correct any mistake,

                  (ii)   to correct, modify or supplement any provision therein
which may be inconsistent with any other provision herein,

                  (iii)  to add any other provisions with respect to matters or
questions arising under this Agreement, or

                  (iv)   to modify, alter, amend, add to or rescind any of the
terms or provisions contained in this Agreement, provided, however, that, in the
case of clauses (iii) and (iv), such amendment will not, as evidenced by an
Opinion of Counsel to such effect, adversely effect in any material respect the
interests of any Holder; provided, further, however, that such amendment will be
deemed to not adversely affect in any material respect the interest of any
Holder if the Person requesting such amendment obtains a letter from each Rating
Agency stating that such amendment will not result in a reduction or withdrawal
of its rating of any Class of 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, without the consent of the
Certificateholders, the Depositor, the Master Servicer, each Servicer, the
Securities Administrator and the Trustee may at any time and from time to time
amend this Agreement to modify, eliminate or add to any of its provisions to
such extent as shall be necessary or appropriate to maintain the qualification
of any of the REMICs provided for herein as REMICs under the Code or to avoid or
minimize the risk of the imposition of any tax on the Trust Fund or any of the
REMICs provided for herein 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 and the Securities Administrator shall have been
provided an Opinion of Counsel, 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 Securities Administrator, 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.

                                     -148-

      This Agreement may also be amended from time to time by the Depositor,
each Servicer, the Securities Administrator, the Trustee and the Holders of the
Certificates affected thereby evidencing not less than 66 2/3% of the Voting
Rights 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, however, 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 2/3% 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, the Trustee
shall not consent to any amendment to this Agreement unless it shall have first
received an Opinion of Counsel, which opinion 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, any of the REMICs provided for herein or the
Certificateholders or cause any of the REMICs provided for herein 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 or upon the written request of
the Trustee to the Securities Administrator, the Securities Administrator 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 Securities Administrator may prescribe.

      Nothing in this Agreement shall require the Trustee or the Securities
Administrator to enter into an amendment without receiving an Opinion of
Counsel, satisfactory to the Trustee or the Securities Administrator 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.

      The Trustee may, but shall not be obligated to, enter into any supplement,
modification or waiver which affects its rights, duties or obligations
hereunder.

      SECTION 11.02. Counterparts.

      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 11.03. Governing Law.

      THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE
SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE

OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HERETO AND THE
CERTIFICATEHOLDERS SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS WITHOUT
REGARD TO THE CONFLICTS OF LAWS PRINCIPLES THEREOF.

      SECTION 11.04. 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 and (ii) the conveyance provided for in
this Agreement shall be deemed to be an assignment and a grant 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 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 11.05. Notices.

            (a)   The Securities Administrator 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 Trustee, the
Securities Administrator or each Servicer and the appointment of any successor;

                  (iv)   The repurchase or substitution of Mortgage Loans
pursuant to Sections 2.02, 2.03 and 3.12;

                  (v)    The final payment to Certificateholders; and

                  (vi)   Any change in the location of the Certificate Account.

      The Securities Administrator shall promptly furnish or make available to
each Rating Agency copies of the following:

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

<PAGE>

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 11.07. Assignment.

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

      SECTION 11.08. 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

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 indemnity satisfactory to it 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.

      SECTION 11.09. Inspection and Audit Rights.

notice, it will permit any representative of the Depositor or the Trustee during
the Master Servicer's or Servicer's normal business hours, to examine all the
books of account, records, reports and other papers of the Master Servicer or
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 or the Trustee and to discuss its affairs, finances
and accounts relating to the Mortgage Loans with its officers, employees,
agents, counsel and independent public accountants (and by this provision the
Master Servicer or Servicer

                                     -152-
<PAGE>

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 or the Trustee of any right under this Section 10.09 shall be
borne by the party requesting such inspection (except in the case of the Trustee

Certificateholder(s)); all other such expenses shall be borne by each Servicer.

      SECTION 11.10. 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
Authenticating Agent pursuant to this Agreement, are and shall be deemed fully
paid.

                                    of the Internal Revenue Code of 1986, as

                                    Pooling and Servicing Agreement

Under penalties of perjury, the undersigned declares that the following is true:

            (1) He or she is an officer of _________________________ (the
                "Transferee"),

            (2) the Transferee's Employer Identification number is __________,

            (3) the Transferee is not a "disqualified organization" (as defined
                below), has no plan or intention of becoming a disqualified
                organization, and is not acquiring any of its interest in the
                Terwin Mortgage Trust, Asset-Backed Certificates, Series TMTS
                2004-3HE, Class R on behalf of a disqualified organization or
                any other entity,

            (4) unless Merrill Lynch Mortgage Investors, Inc.("MLMI") has
                consented to the transfer to the Transferee by executing the
                form of Consent affixed as Appendix B to the Transferee's Letter
                to which this Certificate is affixed as Appendix A, the
                Transferee is a "U.S. person" (as defined below),

            (5) that no purpose of the transfer is to avoid or impede the
                assessment or collection of tax,

            (6) the Transferee has historically paid its debts as they became
                due,

            (7) the Transferee intends, and believes that it will be able, to
                continue to pay its debts as they become due in the future,

            (8) the Transferee understands that, as beneficial owner of the
                Class R Certificate, it may incur tax liabilities in excess of
                any cash flows generated by the Class R Certificate,

            (9) the Transferee intends to pay any taxes associated with holding
                the Class R Certificate as they become due,

            (10) the Transferee consents to any amendment of the Pooling and
                Servicing Agreement that shall be deemed necessary by MLMI (upon
                advice of counsel) to constitute a reasonable arrangement to
                ensure that the Class R Certificate will not be owned directly
                or indirectly by a disqualified organization, and

            (11) IF BRACKETED, THE FOLLOWING CERTIFICATIONS ARE INAPPLICABLE
                [the transfer is not a direct or indirect transfer of the Class
                R Certificate to a foreign permanent establishment or fixed base
                (within the meaning of an applicable income tax treaty) of the
                Transferee, and as to each of the residual interests represented
                by the Class R Certificate, the present value of the anticipated
                tax liabilities associated with holding such residual interest
                does not exceed the sum of:

                                    E-1-4

<PAGE>

            (A) the present value of any consideration given to the Transferee
                to acquire such residual interest;

            (B) the present value of the expected future distributions on such
                residual interest; and

            (C) the present value of the anticipated tax savings associated with
                holding such residual interest as the related REMIC generates
                losses.

      For purposes of this declaration, (i) the Transferee is assumed to pay tax
      at a rate equal to the highest rate of tax specified in Section 11(b)(1)
      of the Code, but the tax rate specified in Section 55(b)(1)(B) of the Code
      may be used in lieu of the highest rate specified in Section 11(b)(1) of
      the Code if the Transferee has been subject to the alternative minimum tax
      under Section 55 of the Code in the preceding two years and will compute
      its taxable income in the current taxable year using the alternative
      minimum tax rate, and (ii) present values are computed using a discount
      rate equal to the Federal short-term rate prescribed by Section 1274(d) of
      the Code for the month of the transfer and the compounding period used by
      the Transferee;]

[(11) (A)   at the time of the transfer, and at the close of each of the
            Transferee's two fiscal years preceding the Transferee's fiscal year
            of transfer, the Transferee's gross assets for financial reporting
            purposes exceed $100 million and its net assets for financial
            reporting purposes exceed $10 million; and

      (B)   the Transferee is an eligible corporation as defined in Treasury
            regulations Section 1.860E-1(c)(6)(i) and has agreed in writing that
            any subsequent transfer of the Class R Certificate will be to
            another eligible corporation in a transaction that satisfies
            Treasury regulation Sections 1.860E-1(c)(4)(i), 1.860E-1(c)(4)(ii),
            1.860E-1(c)(4)(iii) and 1.860E-1(c)(5) and such transfer will not be
            a direct or indirect transfer to a foreign permanent establishment
            (within the meaning of an applicable income tax treaty) of a
            domestic corporation.

For purposes of this declaration, the gross and net assets of the Transferee do
not include any obligation of any related person as defined in Treasury
regulation Section 1.860E-1(c)(6)(ii) or any other asset if a principal purpose
for holding or acquiring the other asset is to permit the Transferee to make
this declaration or to satisfy the requirements of Treasury regulation Section
1.860E-1(c)(5)(i).]

(12)  The Transferee will not cause income from the Class R Certificate to be
attributable to a foreign permanent establishment or fixed base (within the
meaning of an applicable income tax treaty) of the Transferee or another U.S.
taxpayer.
