         This TRUST AGREEMENT, dated as of April 1, 2001 (the "Agreement"), is
by and among STRUCTURED ASSET SECURITIES CORPORATION, a Delaware corporation,
as depositor (the "Depositor"), AURORA LOAN SERVICES INC., as master servicer
(the "Master Servicer"), and THE CHASE MANHATTAN BANK, a New York banking
corporation, as trustee (the "Trustee").

                             PRELIMINARY STATEMENT

         The Depositor has acquired the Mortgage Loans from Lehman Capital, A
Division of Lehman Brothers Holdings Inc. (the "Seller"), and at the Closing
Date is the owner of the Mortgage Loans and the other property being conveyed
by it to the Trustee for inclusion in the Trust Fund. On the Closing Date, the
Depositor will acquire the Certificates from the Trust Fund as consideration
for its transfer to the Trust Fund of the Mortgage Loans and the other
property constituting the Trust Fund. The Depositor has duly authorized the
execution and delivery of this Agreement to provide for the conveyance to the
Trustee of the Mortgage Loans and the other property constituting the Trust
Fund. All covenants and agreements made by the Depositor, the Master Servicer
and the Trustee herein with respect to the Mortgage Loans and the other
property constituting the Trust Fund are for the benefit of the Holders from
time to time of the Certificates. The Depositor and the Master Servicer are
entering into this Agreement, and the Trustee is accepting the Trust Fund
created hereby, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged.

         As provided herein, the Trustee shall elect that the Trust Fund be
treated for federal income tax purposes as comprising two real estate mortgage
investment conduits (each a "REMIC" or, in the alternative, the Lower Tier
REMIC and the Upper Tier REMIC, respectively). Each Certificate, other than
the Class R Certificate, represents ownership of one or more regular interests
in the Upper Tier REMIC for purposes of the REMIC Provisions. The Class R
Certificate represents ownership of the sole class of residual interest in the
Lower Tier REMIC and the Upper Tier REMIC for purposes of the REMIC
Provisions. The Upper Tier REMIC shall hold as assets the several classes of
uncertificated Lower Tier Interests, other than the Class LT-R Interest, set
out below. Each such Lower Tier Interest, other than the Class LT-R, Interest,
is hereby designated as a regular interest in the Lower Tier REMIC. The Lower
Tier REMIC shall hold as assets all property of the Trust Fund other than the
Lower Tier Interests.

         The following table specifies the class designation, interest rate,
and principal amount for each class of Lower Tier Interests.

</TABLE>

         for the Class LT-A1, Class LT-A2, Class LT-A3, Class LT-AR, and LT-B
         Interests shall be a fixed rate per annum of 6.00%. For any

         LT-A1, Class LT-A2, Class LT-A3, Class LT-AR, and LT-B Interests

         Date.

(2)      The Class A4 Certificates are entitled to receive on each
         Distribution Date up to and including the Distribution Date in
         November 2005 a specified portion of the interest payable on the

         each Accrual Period related to a Distribution Date occurring on or
         before the Distribution Date in November 2005 the Class A4
         Certificates are entitled to interest accruals on the Class LT-A1
         Interest at a rate of 0.50%. The Class A4 Certificates are not
         entitled to any distributions after the Distribution Date in November
         2005.

(3)      The Class LT-A5 Interest is an interest-only Class and it does
         not have a principal balance. For each Distribution Date on or before
         the Distribution Date in November 2005, the Class Lt-A5 Interest is
         entitled to receive a specified portion of the interest payable on
         the Non-Discount Mortgage Loans. Specifically, each Accrual period

         November 2005 in Class LT-A5 Interest is entitled to interest
         accruals on the Non-Discount Mortgage Loans at a rate equal to the
         difference between the weighted average of the Net Mortgage Rates of
         the Non-Discount Mortgage Loans and 6.00%. The Class LT-A5 Interest
         is not entitled to any distributions after the Distribution Date in
         November 2005.

(4)      For any Distribution Date on or before the Distribution Date
         in November 2005, the Class LT-A6 Interest shall not be entitled to
         any payments of interest. For any Distribution Date (and the related
         Accrual Period) after the Distribution Date in November 2005, the
         interest rate for the Class LT-A6 Interest shall be a per annum rate
         equal to the Net WAC for such Distribution Date.

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

         On each Distribution Date, the Available Distribution Amount shall be
distributed with respect to the Lower Tier Interests in the following manner:

         (i)      On each Distribution Date, interest is to be
                  distributed on each Lower Tier Regular Interest at the rate
                  described above to the same extent that interest is
                  distributed on the Corresponding Class or Classes of
                  Certificates;

        (ii)      For each Class of Lower Tier Interest for which there
                  is a Corresponding Class of Senior Certificates, principal
                  is to be distributed on such Class of Lower Tier Interest on
                  each Distribution Date in the same manner and in the same
                  amount as principal is distributed on such Corresponding
                  Class of Senior Certificates; and

       (iii)      On each Distribution Date, the excess, if any, of the
                  Available Distribution Amount over the amounts distributed
                  pursuant to clauses (i) and (ii) above is to be distributed
                  as principal on the Class LT-B Interest.

         On each Distribution Date, Realized Losses shall be allocated among
the Lower Tier Interests in the following manner:

         (i)      Realized  Losses (other than the applicable AP Percentage of
                  such Realized Losses) for any  Distribution  Date shall be
                  allocated  first to the Class LT-B Interest  until its
                  principal balance is reduced to zero;

        (ii)      Realized  Losses (other than the AP Percentages of such
                  Realized  Losses)  in excess of the  allocations  made
                  pursuant  to clause  (i) above  are to be  allocated  among
                  the remaining  classes of Lower Tier  Interests  in the same
                  manner that such Realized Losses are allocated among the
                  Corresponding Classes of Certificates; and

       (iii)      The AP Percentage  of Realized  Losses shall be allocated to
                  the Class LT-A6 Interest.

         Net Prepayment Shortfalls and Excess Losses are to be allocated among
the Classes of Lower Tier Interests in the same manner that such items are
allocated among the Corresponding Classes of Certificates.

         The following table specifies the Class designation, Certificate
Interest Rate, initial Class Principal Amount or Class Notional Amount, and

Agreement, the Depositor does hereby transfer, assign, set over, deposit with
and otherwise convey to the Trustee, without recourse, subject to Sections
2.02, 2.04, 2.05 and 2.06, in trust, all the right, title and interest of the
Depositor in and to the Mortgage Loans (including the Participations). Such
conveyance includes, without limitation, the right to all distributions of
principal and interest received on or with respect to the Mortgage Loans on
and after the Cut-off Date other than payments of principal and interest due
on or before such date, and all such payments due after such date but received

received and shall hold the Trust Fund, as trustee, in trust, for the benefit
and use of the Holders of the Certificates and for the purposes and subject to
the terms and conditions set forth in this Agreement, and, concurrently with
such receipt, has caused to be executed, authenticated and delivered to or
upon the order of the Depositor, in exchange for the Trust Fund, Certificates
in the authorized denominations evidencing the entire ownership of the Trust
Fund.

         Concurrently with the execution and delivery of this Agreement, the
Depositor does hereby assign to the Trustee all of its rights and interest
under the Mortgage Loan Sale Agreement; including all rights of the Seller
under the applicable Servicing Agreement to the extent assigned under the
Mortgage Loan Sale Agreement. The Trustee hereby accepts such assignment, and
shall be entitled to exercise all rights of the Depositor under the Mortgage
Loan 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
except as specifically set forth herein.

         In addition, with respect to any Pledged Asset Mortgage Loan, the
Depositor does hereby transfer, assign, set-over and otherwise convey to the
Trustee without recourse (except as provided herein) (i) its rights as
assignee under any security agreements, pledge agreements or guarantees
relating to the Additional Collateral supporting any Pledged Asset Mortgage
Loan, (ii) its security interest in and to any Additional Collateral, (iii)
its right to receive payments in respect of any Pledged Asset Mortgage Loan
pursuant to the Additional Collateral Servicing Agreement, and (iv) its rights
as beneficiary under the Surety Bond in respect of any Pledged Asset Mortgage
Loan.

         (b) In connection with such transfer and assignment, the Depositor
does hereby deliver to, and deposit with, or cause to be delivered to and
deposited with, the Trustee, and/or any custodian acting on the Trustee's
behalf, if applicable, the following documents or instruments with respect to
each Mortgage Loan (each a "Mortgage File") so transferred and assigned (other
than the Participations):

             (i)   with respect to each Mortgage Loan, the original Mortgage
         Note endorsed without recourse in proper form to the order of the
         Trustee, or in blank (in each case, with all necessary intervening
         endorsements as applicable);

            (ii)   the original of any guarantee, security agreement or pledge
         agreement relating to any Additional Collateral and executed in
         connection with the Mortgage Note, assigned to the Trustee;

           (iii)   with respect to each Mortgage Loan other than a Cooperative
         Loan, the original recorded Mortgage with evidence of recording
         indicated thereon and the original recorded power of attorney, if the
         Mortgage was executed pursuant to a power of attorney, with evidence
         of recording thereon or, if such Mortgage or power of attorney has
         been submitted for recording but has not been returned from the
         applicable public recording office, has been lost or is not otherwise
         available, a copy of such Mortgage or power of attorney, as the case
         may be, certified to be a true and complete copy of the original
         submitted for recording. If, in connection with any Mortgage Loan,
         the Depositor cannot deliver the Mortgage with evidence of recording
         thereon on or prior to the Closing Date because of a delay caused by
         the public recording office where such Mortgage has been delivered
         for recordation or because such Mortgage has been lost, the Depositor
         shall deliver or cause to be delivered to the Trustee (or its
         custodian), in the case of a delay due to recording, a true copy of
         such Mortgage, pending delivery of the original thereof, together
         with an Officer's Certificate of the Depositor certifying that the
         copy of such Mortgage delivered to the Trustee (or its custodian) is
         a true copy and that the original of such Mortgage has been forwarded
         to the public recording office, or, in the case of a Mortgage that
         has been lost, a copy thereof (certified as provided for under the
         laws of the appropriate jurisdiction) and a written Opinion of
         Counsel acceptable to the Trustee and the Depositor that an original
         recorded Mortgage is not required to enforce the Trustee's interest
         in the Mortgage Loan;

            (iv)   the original of each assumption, modification or substitution
         agreement, if any, relating to the Mortgage Loans, or, as to any
         assumption, modification or substitution agreement which cannot be
         delivered on or prior to the Closing Date because of a delay caused
         by the public recording office where such assumption, modification or
         substitution agreement has been delivered for recordation, a
         photocopy of such assumption, modification or substitution agreement,
         pending delivery of the original thereof, together with an Officer's
         Certificate of the Depositor certifying that the copy of such
         assumption, modification or substitution agreement delivered to the
         Trustee (or its custodian) is a true copy and that the original of
         such agreement has been forwarded to the public recording office;

             (v)   with respect to each Non-MERS Mortgage Loan other than a
         Cooperative Loan, the original Assignment of Mortgage for each
         Mortgage Loan;

            (vi)   if applicable, such original intervening assignments of
         the Mortgage, notice of transfer or equivalent instrument (each, an
         "Intervening Assignment"), as may be necessary to show a complete
         chain of assignment from the originator, or, in the case of an
         Intervening Assignment that has been lost, a written Opinion of
         Counsel acceptable to the Trustee that such original Intervening
         Assignment is not required to enforce the Trustee's interest in the
         Mortgage Loans;

           (vii)   the original Primary Mortgage Insurance Policy or
         certificate, if private mortgage guaranty insurance is required;

          (viii)   with respect to each Mortgage Loan other than a
         Cooperative Loan, the original mortgagee title insurance policy or
         attorney's opinion of title and abstract of title;

            (ix)   the original of any security agreement, chattel mortgage or
         equivalent executed in connection with the Mortgage or as to any
         security agreement, chattel mortgage or their equivalent that cannot
         be delivered on or prior to the Closing Date because of a delay
         caused by the public recording office where such document has been
         delivered for recordation, a photocopy of such document, pending
         delivery of the original thereof, together with an Officer's
         Certificate of the Depositor certifying that the copy of such
         security agreement, chattel mortgage or their equivalent delivered to
         the Trustee (or its custodian) is a true copy and that the original
         of such document has been forwarded to the public recording office;
         and

             (x)   with respect to any Cooperative Loan, the Cooperative Loan
         Documents.

         The parties hereto acknowledge and agree that the form of endorsement
attached hereto as Exhibit B-4 is intended to effect the transfer to the
Trustee, for the benefit of the Certificateholders, of the Mortgage Notes and
the Mortgages.

         With respect to each Participation, the Depositor does hereby deliver
to, and deposit with, or cause to be delivered to and deposited with, the
Trustee, and/or any custodian acting on the Trustee's behalf, a copy of the
Participation Agreement and the original Participation issued to the Trustee.

         (c)  (i) Assignments of Mortgage with respect to each Non-MERS
Mortgage Loan other than a Cooperative Loan shall be recorded; provided,
however, that such Assignments need not be recorded if, in the Opinion of
Counsel (which must be Independent counsel) acceptable to the Trustee and the
Rating Agencies, recording in such states is not required to protect the
Trustee's interest in the related Non-MERS Mortgage Loans. Subject to the
preceding sentence, as soon as practicable after the Closing Date (but in no
event more than 3 months thereafter except to the extent delays are caused by
the applicable recording office), the Trustee, at the expense of the Depositor
and with the cooperation of the applicable Servicer, shall cause to be
properly recorded by such Servicer in each public recording office where the
related Mortgages are recorded each Assignment of Mortgage referred to in
subsection (b)(v) above with respect to a Non-MERS Mortgage Loan. With respect
to each Cooperative Loan, the Trustee, at the expense of the Depositor and
with the cooperation of the applicable Servicer, shall cause such Servicer to
take such actions as are necessary under applicable law in order to perfect
the interest of the Trustee in the related Mortgaged Property.

             (ii)  With respect to each MERS Mortgage Loan, the Trustee, at the
         expense of the Depositor and at the direction and with the
         cooperation of the applicable Servicer, shall cause to be taken such
         actions as are necessary to cause the Trustee to be clearly
         identified as the owner of each such Mortgage Loan on the records of
         MERS for purposes of the system of recording transfers of beneficial
         ownership of mortgages maintained by MERS.

         (d) In instances where a Title Insurance Policy is required to be
delivered to the Trustee, or to the applicable Custodian on behalf of the
Trustee, under clause (b)(viii) above and is not so delivered, the Depositor
will provide a copy of such Title Insurance Policy to the Trustee, or to the
applicable Custodian on behalf of the Trustee, as promptly as practicable
after the execution and delivery hereof, but in any case within 180 days of
the Closing Date.

         (e) For Mortgage Loans (if any) that have been prepaid in full after
the Cut-off Date and prior to the Closing Date, the Depositor, in lieu of
delivering the above documents, herewith delivers to the Trustee, or to the
applicable Custodian on behalf of the Trustee, an Officer's Certificate which
shall include a statement to the effect that all amounts received in
connection with such prepayment that are required to be deposited in the
applicable Collection Account pursuant to Section 4.01 have been so deposited.
All original documents that are not delivered to the Trustee or the applicable
Custodian on behalf of the Trustee shall be held by the Master Servicer or the
applicable Servicer in trust for the benefit of the Trustee and the
Certificateholders.

         Section 2.02. Acceptance of Trust Fund by Trustee: Review of
Documentation for Trust Fund. (a) The Trustee, by execution and delivery
hereof, acknowledges receipt of the Participations and the Mortgage Files
pertaining to the Mortgage Loans listed on the Mortgage Loan Schedule, subject
to review thereof by the Trustee, or by the applicable Custodian on behalf of
the Trustee, under this Section 2.02. The Trustee, or the applicable Custodian
on behalf of the Trustee, will execute and deliver to the Trustee, the
Depositor and the Master Servicer on the Closing Date an Initial Certification
in the form annexed hereto as Exhibit B-1 (or in the form annexed to the
applicable Custodial Agreement as Exhibit B-1, as applicable).

         (b) Within 45 days after the Closing Date, the applicable Custodian
will, on behalf of the Trustee and for the benefit of Holders of the
Certificates, review each Mortgage File to ascertain that all required
documents set forth in Section 2.01 have been received and appear on their
face to contain the requisite signatures by or on behalf of the respective
parties thereto, and shall deliver to the Trustee, the Depositor and the
Master Servicer an Interim Certification in the form annexed hereto as Exhibit
B-2 (or in the form annexed to the applicable Custodial Agreement as Exhibit
B-2, as applicable) to the effect that, as to each Mortgage Loan listed in the
Mortgage Loan Schedule (other than any Mortgage Loan prepaid in full or any
Mortgage Loan specifically identified in such certification as not covered by
such certification), (i) all of the applicable documents specified in Section
2.01(b) are in its possession and (ii) such documents have been reviewed by it
and appear to relate to such Mortgage Loan. The Trustee, or the applicable
Custodian on behalf of the Trustee, shall make sure that the documents are
executed and endorsed, but shall be under no duty or obligation to inspect,
review or examine any such documents, instruments, certificates or other
papers to determine that the same are valid, binding, legally effective,
properly endorsed, genuine, enforceable or appropriate for the represented
purpose or that they have actually been recorded or are in recordable form or
that they are other than what they purport to be on their face. Neither the
Trustee nor any Custodian shall have any responsibility for verifying the
genuineness or the legal effectiveness of or authority for any signatures of
or on behalf of any party or endorser.

         (c) If in the course of the review described in paragraph (b) above
the Trustee or the applicable Custodian discovers any document or documents
constituting a part of a Mortgage File that is missing, does not appear
regular on its face (i.e., is mutilated, damaged, defaced, torn or otherwise
physically altered) or appears to be unrelated to the Mortgage Loans
identified in the Mortgage Loan Schedule (each, a "Material Defect"), the
Trustee, or the applicable Custodian on behalf of the Trustee, shall promptly
identify the Mortgage Loan to which such Material Defect relates in the
Interim Certificate delivered to the Depositor or the Master Servicer (and to
the Trustee). Within 90 days of its receipt of such notice, the Depositor
shall be required to cure such Material Defect (and, in such event, the
Depositor shall provide the Trustee with an Officer's Certificate confirming
that such cure has been effected). If the Depositor does not so cure such
Material Defect, it shall, if a loss has been incurred with respect to such
Mortgage Loan that would, if such Mortgage Loan were not purchased from the
Trust Fund, constitute a Realized Loss, and such loss is attributable to the
failure of the Depositor to cure such Material Defect, repurchase the related
Mortgage Loan from the Trust Fund at the Purchase Price. A loss shall be
deemed to be attributable to the failure of the Depositor to cure a Material
Defect if, as determined by the Depositor, upon mutual agreement with the
Servicer acting in good faith, absent such Material Defect, such loss would
not have been incurred. Within the two year period following the Closing Date,
the Depositor may, in lieu of repurchasing a Mortgage Loan pursuant to this
Section 2.02, substitute for such Mortgage Loan a Qualifying Substitute
Mortgage Loan subject to the provisions of Section 2.05. The failure of the
Trustee or the applicable Custodian to give the notice contemplated herein
within 45 days after the Closing Date shall not affect or relieve the
Depositor of its obligation to repurchase any Mortgage Loan pursuant to this
Section 2.02 or any other Section of this Agreement requiring the repurchase
of Mortgage Loans from the Trust Fund.

         (d) Within 180 days following the Closing Date, the Trustee, or the
applicable Custodian, shall deliver to the Trustee, the Depositor and the
Master Servicer a Final Certification substantially in the form annexed hereto
as Exhibit B-3 (or in the form annexed to the applicable Custodial Agreement
as Exhibit B-3, as applicable) evidencing the completeness of the Mortgage
Files in its possession or control, with any exceptions noted thereto.

         (e) Nothing in this Agreement shall be construed to constitute an
assumption by the Trust Fund, the Trustee or the Certificateholders of any
unsatisfied duty, claim or other liability on any Mortgage Loan or to any
Mortgagor.

         (f) Each of the parties hereto acknowledges that the Custodian shall
perform the applicable review of the Mortgage Loans and respective
certifications thereof as provided in this Section 2.02.

         Section 2.03. Representations and Warranties of the Depositor. (a)

         into and perform its obligations under this Agreement, and to create
         the trust pursuant hereto;

            (ii)   the execution and delivery by the Depositor of this Agreement
         have been duly authorized by all necessary corporate action on the
         part of the Depositor; neither the execution and delivery of this
         Agreement, nor the consummation of the transactions herein
         contemplated, nor compliance with the provisions hereof, will
         conflict with or result in a breach of, or constitute a default
         under, any of the provisions of any law, governmental rule,
         regulation, judgment, decree or order binding on the Depositor or its
         properties or the certificate of incorporation or bylaws of the
         Depositor;

           (iii)   the execution, delivery and performance by the Depositor of
         this Agreement and the consummation of the transactions contemplated
         hereby do not require the consent or approval of, the giving of
         notice to, the registration with, or the taking of any other action
         in respect of, any state, federal or other governmental authority or
         agency, except such as has been obtained, given, effected or taken
         prior to the date hereof;

            (iv)   this Agreement has been duly executed and delivered by the
         Depositor and, assuming due authorization, execution and delivery by
         the Trustee and the Master Servicer, constitutes a valid and binding
         obligation of the Depositor enforceable against it in accordance with
         its terms except as such enforceability may be subject to (A)
         applicable bankruptcy and insolvency laws and other similar laws
         affecting the enforcement of the rights of creditors generally and
         (B) general principles of equity regardless of whether such
         enforcement is considered in a proceeding in equity or at law;

             (v)   there are no actions, suits or proceedings pending or, to
         the knowledge of the Depositor, threatened or likely to be asserted
         against or affecting the Depositor, before or by any court,
         administrative agency, arbitrator or governmental body (A) with
         respect to any of the transactions contemplated by this Agreement or
         (B) with respect to any other matter which in the judgment of the
         Depositor will be determined adversely to the Depositor and will if
         determined adversely to the Depositor materially and adversely affect
         it or its business, assets, operations or condition, financial or
         otherwise, or adversely affect its ability to perform its obligations
         under this Agreement; and

             (vi)  immediately prior to the transfer and assignment of the
         Mortgage Loans to the Trustee, the Depositor was the sole owner of
         record and holder of each Mortgage Loan, and the Depositor had good
         and marketable title thereto, and had full right to transfer and sell
         each Mortgage Loan to the Trustee free and clear, subject only to (1)
         liens of current real property taxes and assessments not yet due and
         payable and, if the related Mortgaged Property is a condominium unit,
         any lien for common charges permitted by statute, (2) covenants,
         conditions and restrictions, rights of way, easements and other
         matters of public record as of the date of recording of such Mortgage
         acceptable to mortgage lending institutions in the area in which the
         related Mortgaged Property is located and specifically referred to in
         the lender's Title Insurance Policy or attorney's opinion of title and
         abstract of title delivered to the originator of such Mortgage Loan,
         and (3) such other matters to which like properties are commonly
         subject which do not, individually or in the aggregate, materially
         interfere with the benefits of the security intended to be provided by
         the Mortgage, of any encumbrance, equity, participation interest,
         lien, pledge, charge, claim or security interest, and had full right
         and authority, subject to no interest or participation of, or
         agreement with, any other party, to sell and assign each Mortgage Loan
         pursuant to this Agreement.

         (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 Lehman Capital under the Mortgage Loan Sale
Agreement, the only right or remedy of the Trustee or of any Certificateholder
shall be the Trustee's right to enforce the obligations of the applicable
Transferor under any applicable representation or warranty made by it. The
Trustee acknowledges that Lehman Capital shall have no obligation or liability
with respect to any breach of a representation or warranty made by it with
respect to the Mortgage Loans if the fact, condition or event constituting
such breach also constitutes a breach of a representation or warranty made by
the applicable Transferor in the applicable Transfer Agreement, without regard
to whether such Transferor fulfills its contractual obligations in respect of
such representation or warranty. 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 (except as
set forth in Section 2.03(a)(vi)) under any circumstances.

         Section 2.04. Discovery of Breach. It is understood and agreed that
the representations and warranties (i) set forth in Section 2.03, (ii) of
Lehman Capital set forth in the Mortgage Loan Sale Agreement and assigned to
the Trustee by the Depositor hereunder and (iii) of each Transferor, assigned
by Lehman Capital to the Depositor pursuant to the Mortgage Loan 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. Upon discovery by either the Depositor, the Master Servicer 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, the
party discovering such breach shall give prompt written notice to the other
parties. Within 90 days of the discovery of a breach of any representation or
warranty given to the Trustee by the Depositor, any Transferor or Lehman
Capital and assigned to the Trustee, the Depositor, such Transferor or Lehman
Capital, 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 Qualifying Substitute
Mortgage Loan for the affected Mortgage Loan. In the event of discovery of a
breach of any representation and warranty of any Transferor assigned to the
Trustee, the Trustee shall enforce its rights under the applicable Transfer
Agreement and the Mortgage Loan Sale Agreement for the benefit of
Certificateholders. As provided in the Mortgage Loan Sale Agreement, if any
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 Qualifying Substitute Mortgage Loan, under
the terms of the Mortgage Loan Sale Agreement, Lehman Capital 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 Qualifying
Substitute Mortgage Loan.

         Section 2.05. Repurchase, Purchase or Substitution of Mortgage Loans.
(a) With respect to any Mortgage Loan repurchased by the Depositor pursuant to
this Agreement, by Lehman Capital pursuant to the Mortgage Loan Sale Agreement
or by any Transferor pursuant to the applicable Transfer Agreement, the
principal portion of the funds received by the Trustee in respect of such
repurchase of a Mortgage Loan will be considered a Principal Prepayment and
shall be deposited in the Collection Account. The Trustee, upon receipt of the
full amount of the Purchase Price for a Deleted Mortgage Loan, or upon receipt
of the Mortgage File for a Qualifying Substitute Mortgage Loan substituted for
a Deleted Mortgage Loan (and any applicable Substitution Amount), shall
release or cause to be released and reassign to the Depositor, Lehman Capital
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 Trustee (or its
custodian), and the Trustee shall have no further responsibility with respect
to the Mortgage File relating to such Deleted Mortgage Loan.

         (b)  With respect to each Qualifying Substitute Mortgage Loan
to be delivered to the Trustee (or its custodian) pursuant to the terms of
this Article II in exchange for a Deleted Mortgage Loan: (i) the Depositor,
the applicable Transferor or Lehman Capital, as applicable, must deliver to
the Trustee (or its custodian) the Mortgage File for the Qualifying Substitute
Mortgage Loan containing the documents set forth in Section 2.01(b) along with
a written certification certifying as to the delivery of such Mortgage File
and containing the granting language set forth in Section 2.01(a); and (ii)
the Depositor will be deemed to have made, with respect to such Qualified
Substitute Mortgage Loan, each of the representations and warranties made by
it with respect to the related Deleted Mortgage Loan. As soon as practicable
after the delivery of any Qualifying Substitute Mortgage Loan hereunder, the
Trustee, at the expense of the Depositor and at the direction and with the
cooperation of the applicable Servicer, shall (i) with respect to a Qualifying
Substitute Mortgage Loan that is a Non-MERS Mortgage Loan, cause the
Assignment of Mortgage to be recorded by such Servicer if required pursuant to
Section 2.01(c)(i), or (ii) with respect to a Qualifying Substitute Mortgage
Loan that is a MERS Mortgage Loan, cause to be taken such actions as are
necessary to cause the Trustee to be clearly identified as the owner of each
such Mortgage Loan on the records of MERS if required pursuant to Section
2.01(c)(ii).

         (c) 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 Qualifying Substitute
Mortgage Loan for a Deleted Mortgage Loan shall be made unless the Trustee has
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.

         Section 2.06. Grant Clause. It is intended that the conveyance of the
Depositor's right, title and interest in and to property constituting the
Trust Fund pursuant to this Agreement shall constitute, and shall be construed
as, a sale of such property and not a grant of a security interest to secure a
loan. However, if such conveyance is deemed to be in respect of a loan, it is
intended that: (i) the rights and obligations of the parties shall be
established pursuant to the terms of this Agreement; (ii) the Depositor hereby
grants to the Trustee for the benefit of the Holders of the Certificates a
first priority security interest in all of the Depositor's right, title and
interest in, to and under, whether now owned or hereafter acquired, the Trust
Fund and all proceeds of any and all property constituting the Trust Fund to
secure payment of the Certificates; and (iii) this Agreement shall constitute
a security agreement under applicable law. If such conveyance is deemed to be
in respect of a loan and the Trust created by this Agreement terminates prior
to the satisfaction of the claims of any Person holding any Certificate, 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, and all proceeds shall be distributed as herein provided.

                                 Article III

                               THE CERTIFICATES

         Section 3.01. The Certificates. (a) The Certificates shall be
issuable in registered form only and shall be securities governed by Article 8
of the New York Uniform Commercial Code. The Book-Entry Certificates will be
evidenced by one or more certificates, beneficial ownership of which will be
held in the dollar denominations in Certificate Principal Amount or Notional
Principal Amount, as applicable, or in the Percentage Interests, specified
herein. Each Class of Book-Entry Certificates shall be issued in the minimum
denominations in Certificate Principal Amount (or Notional Amount) or
Percentage Interest specified in the Preliminary Statement hereto and in
integral multiples of $1 or 5% (in the case of Certificates issued in
Percentage Interests) in excess thereof. Each Class of Non-Book Entry
Certificates other than the Residual Certificate shall be issued in
definitive, fully registered form in the minimum denominations in Certificate
Principal Amount (or Notional Amount) specified in the Preliminary Statement
hereto and in integral multiples of $1 in excess thereof. The Residual
Certificate shall be issued as a single Certificate and maintained in
definitive, fully registered form in a minimum denomination equal to 100% of
the Percentage Interest of such Class. The Certificates may be issued in the
form of typewritten certificates. One Certificate of each Class of
Certificates other than any Class of Residual Certificates may be issued in
any denomination in excess of the minimum denomination.

         (b) The Certificates shall be executed by manual or facsimile
signature on behalf of the Trustee by an authorized officer. Each Certificate
shall, on original issue, be authenticated by the Trustee upon the order of
the Depositor upon receipt by the Trustee of the Mortgage Files described in
Section 2.01. 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 provided
for herein, executed by an authorized officer of the Trustee or the
Authenticating Agent, if any, by manual signature, and such certification 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. At any time and
from time to time after the execution and delivery of this Agreement, the
Depositor may deliver Certificates executed by the Depositor to the Trustee or
the Authenticating Agent for authentication and the Trustee or the
Authenticating Agent shall authenticate and deliver such Certificates as in
this Agreement provided and not otherwise.

         (c) The Class B4, Class B5 or Class B6 Certificates offered and sold
in reliance on the exemption from registration under Rule 144A shall be issued
initially in the form of one or more permanent global Certificates in
definitive, fully registered form without interest coupons with the applicable
legends set forth in Exhibit A added to the forms of such Certificates (each,
a "Restricted Global Security"), which shall be deposited on behalf of the
subscribers for such Certificates represented thereby with the Trustee, as
custodian for DTC and registered in the name of a nominee of DTC, duly
executed and authenticated by the Trustee as hereinafter provided. The
aggregate principal amounts of the Restricted Global Securities may from time
to time be increased or decreased by adjustments made on the records of the
Trustee or DTC or its nominee, as the case may be, as hereinafter provided.

         The Class B4, Class B5 or Class B6 Certificates sold in offshore
transactions in reliance on Regulation S shall be issued initially in the form
of one or more permanent global Certificates in definitive, fully registered
form without interest coupons with the applicable legends set forth in Exhibit
A hereto added to the forms of such Certificates (each, a "Regulation S Global
Security"), which shall be deposited on behalf of the subscribers for such
Certificates represented thereby with the Trustee, as custodian for DTC and
registered in the name of a nominee of DTC, duly executed and authenticated by
the Trustee as hereinafter provided. The aggregate principal amounts of the
Regulation S Global Securities may from time to time be increased or decreased
by adjustments made on the records of the Trustee or DTC or its nominee, as
the case may be, as hereinafter provided.

         Section 3.02. Registration. The Trustee is hereby appointed, and
hereby accepts its appointment as, Certificate Registrar in respect of the
Certificates and shall maintain books for the registration and for the
transfer of Certificates (the "Certificate Register"). The Trustee may appoint
a bank or trust company to act as Certificate Registrar. A registration book
shall be maintained for the Certificates collectively. The Certificate
Registrar may resign or be discharged or removed and a new successor may be
appointed in accordance with the procedures and requirements set forth in
Sections 6.06 and 6.07 hereof with respect to the resignation, discharge or
removal of the Trustee and the appointment of a successor Trustee. The
Certificate Registrar may appoint, by a written instrument delivered to the
Holders and the Master Servicer, any bank or trust company to act as
co-registrar under such conditions as the Certificate Registrar may prescribe;
provided, however, that the Certificate Registrar shall not be relieved of any
of its duties or responsibilities hereunder by reason of such appointment.

         Section 3.03. Transfer and Exchange of Certificates. (a) A
Certificate (other than Book-Entry Certificates which shall be subject to
Section 3.09 hereof) may be transferred by the Holder thereof only upon
presentation and surrender of such Certificate at the office of the
Certificate Registrar duly endorsed or accompanied by an assignment duly
executed by such Holder or his duly authorized attorney in such form as shall
be satisfactory to the Certificate Registrar. Upon the transfer of any
Certificate in accordance with the preceding sentence, the Trustee shall
execute, and the Trustee or any Authenticating Agent shall authenticate and
deliver to the transferee, one or more new Certificates of the same Class and
evidencing, in the aggregate, the same aggregate Certificate Principal Amount
as the Certificate being transferred. No service charge shall be made to a
Certificateholder for any registration of transfer of Certificates, but the
Certificate Registrar may require payment of a sum sufficient to cover any tax
or governmental charge that may be imposed in connection with any registration
of transfer of Certificates.

         (b) A Certificate may be exchanged by the Holder thereof for any
number of new Certificates of the same Class, in authorized denominations,
representing in the aggregate the same Certificate Principal Amount as the
Certificate surrendered, upon surrender of the Certificate to be exchanged at
the office of the Certificate Registrar duly endorsed or accompanied by a
written instrument of transfer duly executed by such Holder or his duly
authorized attorney in such form as is satisfactory to the Certificate
Registrar. Certificates delivered upon any such exchange will evidence the
same obligations, and will be entitled to the same rights and privileges, as
the Certificates surrendered. No service charge shall be made to a
Certificateholder for any exchange of Certificates, but the Certificate
Registrar may require payment of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with any exchange of
Certificates. Whenever any Certificates are so surrendered for exchange, the
Trustee shall execute, and the Trustee or the Authenticating Agent shall
authenticate, date and deliver the Certificates which the Certificateholder
making the exchange is entitled to receive.

         (c) By acceptance of a Restricted Certificate or 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 transfer such a
Certificate only as provided herein. In addition, each Holder of a Regulation
S Global Security shall be deemed to have represented and warranted to the
Trustee, the Certificate Registrar 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 of 1933, as amended (the "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 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.

         The following restrictions shall apply with respect to the transfer
and registration of transfer of a Restricted Certificate to a transferee that
takes delivery in the form of a Definitive Certificate:

            (i)    The Certificate Registrar shall register the transfer of a
         Restricted Certificate if the requested transfer is (x) to the
         Depositor or the Placement Agent, an affiliate (as defined in Rule
         405 under the Act) of the Depositor or the Placement Agent or (y)
         being made to a QIB by a transferor that has provided the Trustee
         with a certificate in the form of Exhibit F hereto; and

           (ii)    The Certificate Registrar shall register the transfer of a
         Restricted Certificate if the requested transfer is being made to an
         "accredited investor" under Rule 501(a)(1), (2), (3) or (7) under the
         Act by a transferor who furnishes to the Trustee a letter of the
         transferee substantially in the form of Exhibit G hereto.

         (d) (i) No transfer of an ERISA-Restricted Certificate in the form of
a Definitive Certificate shall be made to any Person unless the Trustee has
received (A) a certificate substantially in the form of Exhibit H (or Exhibit
D-1 in the case of the Class R Certificate) hereto from such transferee or (B)
an Opinion of Counsel satisfactory to the Trustee and the Depositor to the
effect that the purchase and holding of such a Certificate will not constitute
or result in the assets of the Trust Fund being deemed to be "plan assets"
subject to the prohibited transactions provisions of ERISA or Section 4975 of
the Code and will not subject the Trustee or the Depositor to any obligation
in addition to those undertaken in the Agreement; provided, however, that the
Trustee will not require such certificate or opinion in the event that, as a
result of a change of law or otherwise, counsel satisfactory to the Trustee
has rendered an opinion to the effect that the purchase and holding of an
ERISA-Restricted Certificate by a Plan or a Person that is purchasing or
holding such a Certificate with the assets of a Plan will not constitute or
result in a prohibited transaction under ERISA or Section 4975 of the Code.
Each transferee of an ERISA-Restricted Certificate that is a Book Entry
Certificate shall be deemed to have made the representations set forth in
Exhibit H. The preparation and delivery of the certificate and opinions
referred to above shall not be an expense of the Trust Fund, the Trustee or
the Depositor. Notwithstanding the foregoing, no opinion or certificate shall
be required for the initial issuance of the ERISA-Restricted Certificates.

         (e) As a condition of the registration of transfer or exchange of any
Certificate, the Certificate Registrar may require the certified taxpayer
identification number of the owner of the Certificate and the payment of a sum
sufficient to cover any tax or other governmental charge imposed in connection
therewith; provided, however, that the Certificate Registrar shall have no
obligation to require such payment or to determine whether or not any such tax
or charge may be applicable. No service charge shall be made to the
Certificateholder for any registration, transfer or exchange of Certificate.

         (f) Notwithstanding anything to the contrary contained herein, no
Residual Certificate may be owned, pledged or transferred, directly or
indirectly, by or to (i) a Disqualified Organization or (ii) an individual,
corporation or partnership or other person unless such person is (A) not a
Non-U.S. Person or (B) is a Non-U.S. Person that holds a Residual Certificate
in connection with the conduct of a trade or business within the United States
and has furnished the transferor and the Trustee with an effective Internal
Revenue Service Form W-8ECI or successor form at the time and in the manner
required by the Code (any such person who is not covered by clause (A) or (B)
above is referred to herein as a "Non-permitted Foreign Holder").

         Prior to and as a condition of the registration of any transfer, sale
or other disposition of a Residual Certificate, the proposed transferee shall
deliver to the Trustee an affidavit in substantially the form attached hereto
as Exhibit D-1 representing and warranting, among other things, that such
transferee is neither a Disqualified Organization, an agent or nominee acting
on behalf of a Disqualified Organization, nor a Non-permitted Foreign Holder
(any such transferee, a "Permitted Transferee"), and the proposed transferor
shall deliver to the Trustee an affidavit in substantially the form attached
hereto as Exhibit D-2. In addition, the Trustee may (but shall have no
obligation to) require, prior to and as a condition of any such transfer, the
delivery by the proposed transferee of an Opinion of Counsel, addressed to the
Depositor and the Trustee satisfactory in form and substance to the Depositor,
that such proposed transferee or, if the proposed transferee is an agent or
nominee, the proposed beneficial owner, is not a Disqualified Organization,
agent or nominee thereof, or Non-permitted Foreign Holder. Notwithstanding the
registration in the Certificate Register of any transfer, sale, or other
disposition of a Residual Certificate to a Disqualified Organization, an agent
or nominee thereof, or Non-permitted Foreign Holder, such registration shall
be deemed to be of no legal force or effect whatsoever and such Disqualified
Organization, agent or nominee thereof, or Non-permitted Foreign Holder shall
not be deemed to be a Certificateholder for any purpose hereunder, including,
but not limited to, the receipt of distributions on such Residual Certificate.
The Trustee shall not be under any liability to any person for any
registration or transfer of a Residual Certificate to a Disqualified
Organization, agent or nominee thereof, or Non-permitted Foreign Holder or for
the maturity of any payments due on such Residual Certificate to the Holder
thereof or for taking any other action with respect to such Holder under the
provisions of the Agreement, so long as the transfer was effected in
accordance with this Section 3.03(f), unless the Trustee shall have actual
knowledge at the time of such transfer or the time of such payment or other
action that the transferee is a Disqualified Organization, agent or nominee
thereof, or Non-permitted Foreign Holder. The Trustee shall be entitled to
recover from any Holder of a Residual Certificate that was a Disqualified
Organization, agent or nominee thereof, or Non-permitted Foreign Holder at the
time it became a Holder or any subsequent time it became a Disqualified
Organization, agent or nominee thereof, or Non-permitted Foreign Holder, all
payments made on such Residual Certificate at and after either such times (and
all costs and expenses, including but not limited to attorneys' fees, incurred
in connection therewith). Any payment (not including any such costs and
expenses) so recovered by the Trustee shall be paid and delivered to the last
preceding Holder of such Residual Certificate.

         If any purported transferee shall become a registered Holder of a
Residual Certificate in violation of the provisions of this Section 3.03(f),
then upon receipt of written notice to the Trustee that the registration of
transfer of such Residual Certificate was not in fact permitted by this
Section 3.03(f), the last preceding Permitted Transferee shall be restored to
all rights as Holder thereof retroactive to the date of such registration of
transfer of such Residual Certificate. The Trustee shall be under no liability
to any Person for any registration of transfer of a Residual Certificate that
is in fact not permitted by this Section 3.03(f), for making any payment due
on such Certificate to the registered Holder thereof or for taking any other
action with respect to such Holder under the provisions of this Agreement so
long as the transfer was registered upon receipt of the affidavit described in
the preceding paragraph of this Section 3.03(f).

         (g) Each Holder of a Residual Certificate, by such Holder's
acceptance thereof, shall be deemed for all purposes to have consented to the
provisions of this section.

         (h) Notwithstanding any provision to the contrary herein, so long as
a Global Security representing either of the Class B4, Class B5 or Class B6
Certificates remains outstanding and is held by or on behalf of DTC, transfers
of a Global Security representing any such Certificates, in whole or in part,
shall only be made in accordance with Section 3.01 and this Section 3.03(h).

             (A)   Subject to clauses (B) and (C) of this Section 3.03(h),
         transfers of a Global Security representing either of the Class B4,
         Class B5 or Class B6 Certificates shall be limited to transfers of
         such Global Security, in whole or in part, to nominees of DTC or to a
         successor of DTC or such successor's nominee.

             (B)   Restricted Global Security to Regulation S Global Security.
         If a holder of a beneficial interest in a Restricted Global Security
         deposited with or on behalf of DTC wishes at any time to exchange
         its interest in such Restricted Global Security for an interest in a
         Regulation S Global Security, or to transfer its interest in such
         Restricted Global Security to a Person who wishes to take delivery
         thereof in the form of an interest in a Regulation S Global
         Security, such holder, provided such holder is not a U.S. person,
         may, subject to the rules and procedures of DTC, exchange or cause
         the exchange of such interest for an equivalent beneficial interest
         in the Regulation S Global Security. Upon receipt by the Trustee, as
         Certificate Registrar, of (I) instructions from DTC directing the
         Trustee, as Certificate Registrar, to be credited a beneficial
         interest in a Regulation S Global Security in an amount equal to the
         beneficial interest in such Restricted Global Security to be
         exchanged but not less than the minimum denomination applicable to
         such holder's Certificates held through a Regulation S Global
         Security, (II) a written order given in accordance with DTC's
         procedures containing information regarding the participant account
         of DTC and, in the case of a transfer pursuant to and in accordance
         with Regulation S, the Euroclear or Clearstream account to be
         credited with such increase and (III) a certificate in the form of
         Exhibit L-1 hereto given by the holder of such beneficial interest
         stating that the exchange or transfer of such interest has been made
         in compliance with the transfer restrictions applicable to the
         Global Securities, including that the holder is not a U.S. person,
         and pursuant to and in accordance with Regulation S, the Trustee, as
         Certificate Registrar, shall reduce the principal amount of the
         Restricted Global Security and increase the principal amount of the
         Regulation S Global Security by the aggregate principal amount of
         the beneficial interest in the Restricted Global Security to be
         exchanged, and shall instruct Euroclear or Clearstream, as
         applicable, concurrently with such reduction, to credit or cause to
         be credited to the account of the Person specified in such
         instructions a beneficial interest in the Regulation S Global
         Security equal to the reduction in the principal amount of the
         Restricted Global Security.

             (C)   Regulation S Global Security to Restricted Global Security.
         If a holder of a beneficial interest in a Regulation S Global
         Security deposited with or on behalf of DTC wishes at any time to
         transfer its interest in such Regulation S Global Security to a
         Person who wishes to take delivery thereof in the form of an
         interest in a Restricted Global Security, such holder may, subject
         to the rules and procedures DTC, exchange or cause the exchange of
         such interest for an equivalent beneficial interest in a Restricted
         Global Security. Upon receipt by the Trustee, as Certificate
         Registrar, of (I) instructions from DTC directing the Trustee, as
         Certificate Registrar, to cause to be credited a beneficial interest
         in a Restricted Global Security in an amount equal to the beneficial
         interest in such Regulation S Global Security to be exchanged but
         not less than the minimum denomination applicable to such holder's
         Certificates held through a Restricted Global Security, to be
         exchanged, such instructions to contain information regarding the
         participant account with DTC to be credited with such increase, and
         (II) a certificate in the form of Exhibit L-2 hereto given by the
         holder of such beneficial interest and stating, among other things,
         that the Person transferring such interest in such Regulation S
         Global Security reasonably believes that the Person acquiring such
         interest in a Restricted Global Security is a QIB, is obtaining such
         beneficial interest in a transaction meeting the requirements of
         Rule 144A and in accordance with any applicable securities laws of
         any State of the United States or any other jurisdiction, then the
         Trustee, as Certificate Registrar, will reduce the principal amount
         of the Regulation S Global Security and increase the principal
         amount of the Restricted Global Security by the aggregate principal
         amount of the beneficial interest in the Regulation S Global
         Security to be transferred and the Trustee, as Certificate
         Registrar, shall instruct DTC, concurrently with such reduction, to
         credit or cause to be credited to the account of the Person
         specified in such instructions a beneficial interest in the
         Restricted Global Security equal to the reduction in the principal
         amount of the Regulation S Global Security.

             (D)   Other Exchanges. In the event that a Global Security is
         exchanged for Certificates in definitive registered form without
         interest coupons, pursuant to Section 3.09(c) hereof, such
         Certificates may be exchanged for one another only in accordance
         with such procedures as are substantially consistent with the
         provisions above (including certification requirements intended to
         insure that such transfers comply with Rule 144A, comply with Rule
         501(a)(1), (2), (3) or (7) or are to non-U.S. persons in compliance
         with Regulation S under the Act, as the case may be), and as may be
         from time to time adopted by the Trustee.

             (E)   Restrictions on U.S. Transfers. Transfers of interests in
         the Regulation S Global Security to U.S. persons (as defined in
         Regulation S) shall be limited to transfers made pursuant to the
         provisions of Section 3.03(h)(C).

         Section 3.04. Cancellation of Certificates. Any Certificate
surrendered for registration of transfer or exchange shall be cancelled and
retained in accordance with normal retention policies with respect to
cancelled certificates maintained by the Trustee or the Certificate Registrar.

         Section 3.05. Replacement of Certificates. If (i) any Certificate is
mutilated and is surrendered to the Trustee or any Authenticating Agent or
(ii) the Trustee or any Authenticating Agent receives evidence to its
satisfaction of the destruction, loss or theft of any Certificate, and there
is delivered to the Trustee or the Authenticating Agent such security or
indemnity as may be required by them to save each of them harmless, then, in
the absence of notice to the Depositor and any Authenticating Agent that such
destroyed, lost or stolen Certificate has been acquired by a bona fide
purchaser, the Trustee shall execute and the Trustee or any Authenticating
Agent shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
tenor and Certificate Principal Amount. Upon the issuance of any new
Certificate under this Section 3.05, the Trustee and Authenticating Agent may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses
(including the fees and expenses of the Trustee or the Authenticating Agent)
connected therewith. Any replacement Certificate issued pursuant to this
Section 3.05 shall constitute complete and indefeasible evidence of ownership
in the applicable Trust Fund, as if originally issued, whether or not the
lost, stolen or destroyed Certificate shall be found at any time.

         Section 3.06. Persons Deemed Owners. Subject to the provisions of
Section 3.09 with respect to Book-Entry Certificates, the Depositor, the
Master Servicer, the Trustee, the Certificate Registrar and any agent of any
of them may treat the Person in whose name any Certificate is registered upon
the books of the Certificate Registrar as the owner of such Certificate for
the purpose of receiving distributions pursuant to Sections 5.01 and 5.02 and
for all other purposes whatsoever, and neither the Depositor, the Master
Servicer, the Trustee, the Certificate Registrar nor any agent of any of them
shall be affected by notice to the contrary.

         Section 3.07. Temporary Certificates. (a) Pending the preparation of
definitive Certificates, upon the order of the Depositor, the Trustee shall
execute and shall authenticate and deliver temporary Certificates that are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any
authorized denomination, substantially of the tenor of the definitive
Certificates in lieu of which they are issued and with such variations as the
authorized officers executing such Certificates may determine, as evidenced by
their execution of such Certificates.

         (b) If temporary Certificates are issued, the Depositor will cause
definitive Certificates to be prepared without unreasonable delay. After the
preparation of definitive Certificates, the temporary Certificates shall be
exchangeable for definitive Certificates upon surrender of the temporary
Certificates at the office or agency of the Trustee without charge to the
Holder. Upon surrender for cancellation of any one or more temporary
Certificates, the Trustee shall execute and authenticate and deliver in
exchange therefor a like aggregate Certificate Principal Amount of definitive
Certificates of the same Class in the authorized denominations. Until so
exchanged, the temporary Certificates shall in all respects be entitled to the
same benefits under this Agreement as definitive Certificates of the same
Class.

         Section 3.08. Appointment of Paying Agent. The Trustee may appoint a
Paying Agent (which may be the Trustee) for the purpose of making
distributions to Certificateholders hereunder. The Trustee shall cause such
Paying Agent to execute and deliver to the Trustee an instrument in which such
Paying Agent shall agree with the Trustee that such Paying Agent will hold all
sums held by it for the payment to Certificateholders in an Eligible Account
in trust for the benefit of the Certificateholders entitled thereto until such
sums shall be paid to the Certificateholders. All funds remitted by the
Trustee to any such Paying Agent for the purpose of making distributions shall
be paid to Certificateholders on each Distribution Date and any amounts not so
paid shall be returned on such Distribution Date to the Trustee. If the Paying
Agent is not the Trustee, the Trustee shall cause to be remitted to the Paying
Agent on or before the Business Day prior to each Distribution Date, by wire
transfer in immediately available funds, the funds to be distributed on such
Distribution Date. Any Paying Agent shall be either a bank or trust company or
otherwise authorized under law to exercise corporate trust powers.

         Section 3.09. Book-Entry Certificates. (a) Each Class of Book-Entry
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 Trust Company, the initial Clearing Agency, by, or
on behalf of, the Depositor. The Book-Entry Certificates shall initially be
registered on the Certificate Register in the name of the nominee of the
Clearing Agency, and no Certificate Owner will receive a definitive
certificate representing such Certificate Owner's interest in the Book-Entry
Certificates, except as provided in Section 3.09(c). Unless Definitive
Certificates have been issued to Certificate Owners of Book-Entry Certificates
pursuant to Section 3.09(c):

               (i) the provisions of this Section 3.09 shall be in full force
          and effect;

              (ii) the Depositor, the Master Servicer, the Paying Agent, the
          Registrar and the Trustee may deal with the Clearing Agency for all
          purposes (including the making of distributions on the Book-Entry
          Certificates) as the authorized representatives of the Certificate
          Owners and the Clearing Agency shall be responsible for crediting
          the amount of such distributions to the accounts of such Persons
          entitled thereto, in accordance with the Clearing Agency's normal
          procedures;

             (iii) to the extent that the provisions of this Section 3.09
          conflict with any other provisions of this Agreement, the provisions
          of this Section 3.09 shall control; and

              (iv) the rights of Certificate Owners shall be exercised only
          through the Clearing Agency and the Clearing Agency Participants and
          shall be limited to those established by law and agreements between
          such Certificate Owners and the Clearing Agency and/or the Clearing
          Agency Participants. Unless and until Definitive Certificates are
          issued pursuant to Section 3.09(c), the initial Clearing Agency will
          make book-entry transfers among the Clearing Agency Participants and
          receive and transmit distributions of principal of and interest on
          the Book-Entry Certificates to such Clearing Agency Participants.

         (b) Whenever notice or other communication to the Certificateholders
is required under this Agreement, unless and until Definitive Certificates
shall have been issued to Certificate Owners pursuant to Section 3.09(c), the
Trustee shall give all such notices and communications specified herein to be
given to Holders of the Book-Entry Certificates to the Clearing Agency.

         (c) If (i) (A) the Depositor advises the Trustee in writing that the
Clearing Agency is no longer willing or able to discharge properly its
responsibilities with respect to the Book-Entry Certificates, and (B) the
Trustee or the Depositor is unable to locate a qualified successor, (ii) the
Depositor, at its option, advises the Trustee in writing that it elects to
terminate the book-entry system through the Clearing Agency or (iii) after the
occurrence of an Event of Default, Certificate Owners representing beneficial
interests aggregating not less than 50% of the Class Principal Amount of a
Class of Book-Entry Certificates identified as such to the Trustee by an
Officer's Certificate from the Clearing Agency advise the Trustee and the
Clearing Agency through the Clearing Agency Participants in writing that the
continuation of a book-entry system through the Clearing Agency is no longer
in the best interests of the Certificate Owners of a Class of Book-Entry
Certificates, the Trustee shall notify or cause the Certificate Registrar to
notify the Clearing Agency to effect notification to all Certificate Owners,
through the Clearing Agency, of the occurrence of any such event and of the
availability of Definitive Certificates to Certificate Owners requesting the
same. Upon surrender to the Trustee of the Book-Entry Certificates by the
Clearing Agency, accompanied by registration instructions from the Clearing
Agency for registration, the Trustee shall issue the Definitive Certificates.
Neither the Transferor nor the Trustee shall be liable for any delay in
delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions. Upon the issuance of Definitive
Certificates all references herein to obligations imposed upon or to be
performed by the Clearing Agency shall be deemed to be imposed upon and
performed by the Trustee, to the extent applicable, with respect to such
Definitive Certificates and the Trustee shall recognize the holders of the
Definitive Certificates as Certificateholders hereunder.

                                  Article IV

                       ADMINISTRATION OF THE TRUST FUND

         Section 4.01. Collection Account. (a) On the Closing Date, the Master
Servicer shall open and shall thereafter maintain a segregated account held in
trust (the "Collection Account"), entitled "Aurora Loan Services Inc., as
Master Servicer, in trust for the benefit of the Holders of Structured Asset
Securities Corporation Mortgage Pass-Through Certificates, Series 2001-7A."
The Collection Account shall relate solely to the Certificates issued by the
Trust Fund hereunder, and funds in such Collection Account shall not be
commingled with any other monies.

         (b) The Collection Account shall be an Eligible Account. If an
existing Collection Account ceases to be an Eligible Account, the Master
Servicer shall establish a new Collection Account that is an Eligible Account
within 30 days and transfer all funds on deposit in such existing Collection
Account into such new Collection Account.

         (c) The Master Servicer shall give to the Trustee prior written
notice of the name and address of the depository institution at which the
Collection Account is maintained and the account number of such Collection
Account. On each Deposit Date, the entire amount on deposit in the Collection
Account (subject to permitted withdrawals set forth in Section 4.02),
excluding such amounts not included in the Available Distribution Amount for
such Distribution Date pursuant to clauses (A) through (F) of paragraph (i) of
the definition thereof, shall be remitted to the Trustee for deposit into the
Certificate Account by wire transfer in immediately available funds. The
Master Servicer, at its option, may choose to make daily remittances from the
Collection Account to the Trustee for deposit into the Certificate Account.

         (d) The Master Servicer shall deposit or cause to be deposited into
the Collection Account, no later than the Business Day following the Closing
Date, any amounts representing Scheduled Payments on the Mortgage Loans due
after the Cut-off Date and received by the Master Servicer on or before the
Closing Date. Thereafter, the Master Servicer shall deposit or cause to be
deposited in the Collection Account on the applicable Remittance Date the
following amounts received or payments made by it (other than in respect of
principal of and interest on the Mortgage Loans due on or before the Cut-Off
Date):

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

              (ii) all payments on account of interest on the Mortgage
          Loans (other than payments due prior to the Cut-off Date), net of
          the applicable Servicing Fee and Master Servicing Fee with respect
          to each such Mortgage Loan, but only to the extent of the amount
          permitted to be withdrawn or withheld from the Collection Account in
          accordance with Sections 5.04 and 9.21;

             (iii) any unscheduled payment or other recovery with respect to
          a Mortgage Loan not otherwise specified in this paragraph (d),
          including all Net Liquidation Proceeds with respect to the Mortgage
          Loans and REO Property, and all amounts received in connection with
          the operation of any REO Property, net of any unpaid Servicing Fees
          and Master Servicing Fees with respect to such Mortgage Loans, but
          only to the extent of the amount permitted to be withdrawn or
          withheld from the Collection Account in accordance with Sections
          5.04 and 9.21; provided that if the applicable Servicer is also the
          Retained Interest Holder with respect to any Mortgage Loan, payments
          on account of interest on the Mortgage Loans as to which such
          Servicer is the Retained Interest Holder may also be made net of the
          related Retained Interest with respect to each such Mortgage Loan.

              (iv) all Insurance Proceeds;

               (v) all Advances made by the Master Servicer or the applicable
          Servicer pursuant to Section 5.04 or the applicable Servicing
          Agreement; and

              (vi) all proceeds of any Mortgage Loan purchased by any Person.

         (e) Funds in the Collection Account may be invested in Eligible
Investments (selected by and at the written direction of the Master Servicer)
which shall mature not later than the earlier of (a) the Deposit Date (except
that if such Eligible Investment is an obligation of the Trustee or the Paying
Agent, if other than the Trustee, and such Collection Account is maintained
with the Trustee or the Paying Agent, if other than the Trustee, then such
Eligible Investment shall mature not later than such applicable Distribution
Date) or (b) the day on which the funds in such Collection Account are
required to be remitted to the Trustee for deposit into the Certificate
Account, and any such Eligible Investment shall not be sold or disposed of
prior to its maturity. All such Eligible Investments shall be made in the name
of the Trustee (in its capacity as such) or its nominee. All income and gain
realized from any such investment shall be for the benefit of the Master
Servicer and shall be subject to its withdrawal or order from time to time,
subject to Section 5.05, and shall not be part of the Trust Fund. The amount
of any losses incurred in respect of any such investments shall be deposited
in such Collection Account by the Master Servicer out of its own funds,
without any right of reimbursement therefor, immediately as realized. The
foregoing requirements for deposit in the Collection Account are exclusive, it
being understood and agreed that, without limiting the generality of the
foregoing, payments of interest on funds in the Collection Account and
payments in the nature of late payment charges or assumption fees need not be
deposited by the Master Servicer in the Collection Account and may be retained
by the Master Servicer or the applicable Servicer as additional servicing
compensation. If the Master Servicer deposits in the Collection Account any
amount not required to be deposited therein, it may at any time withdraw such
amount from such Collection Account. In the event the Master Servicer does not
provide written direction to the Trustee pursuant to this Section, all funds
on deposit in the Collection Account shall remain uninvested.

         Section 4.02. Application of Funds in the Collection Account. The
Master Servicer may, from time to time, make, or cause to be made, withdrawals
from the Collection Account for the following purposes:

               (i) to reimburse itself or any Servicer for Advances made by it
          or by such Servicer pursuant to Section 5.04 or the applicable
          Servicing Agreement; the Master Servicer's right to reimburse itself
          pursuant to this subclause (i) is limited to amounts received on or
          in respect of particular Mortgage Loans (including, for this
          purpose, Liquidation Proceeds and amounts representing Insurance
          Proceeds with respect to the property subject to the related
          Mortgage) which represent late recoveries (net of the applicable
          Servicing Fee and the Master Servicing Fee) of payments of principal
          or interest respecting which any such Advance was made, it being
          understood, in the case of any such reimbursement, that the Master
          Servicer's or Servicer's right thereto shall be prior to the rights
          of the Certificateholders;

              (ii) to reimburse itself or any Servicer for any
          Servicing Advances made by it or by such Servicer that it determines
          in good faith will not be recoverable from amounts representing late
          recoveries of payments of principal or interest respecting the
          particular Mortgage Loan as to which such Servicing Advance was made
          or from Liquidation Proceeds or Insurance Proceeds with respect to
          such Mortgage Loan, it being understood, in the case of any such
          reimbursement, that such Master Servicer's or Servicer's right
          thereto shall be prior to the rights of the Certificateholders;

             (iii) to reimburse itself or any Servicer from Liquidation
          Proceeds for Liquidation Expenses and for amounts expended by it
          pursuant to Sections 9.20 and 9.22(a) or the applicable Servicing
          Agreement in good faith in connection with the restoration of
          damaged property and, to the extent that Liquidation Proceeds after
          such reimbursement exceed the unpaid principal balance of the
          related Mortgage Loan, together with accrued and unpaid interest
          thereon at the applicable Mortgage Rate less the applicable
          Servicing Fee and the Master Servicing Fee for such Mortgage Loan to
          the Due Date next succeeding the date of its receipt of such
          Liquidation Proceeds, to pay to itself out of such excess the amount
          of any unpaid assumption fees, late payment charges or other
          Mortgagor charges on the related Mortgage Loan and to retain any
          excess remaining thereafter as additional servicing compensation, it
          being understood, in the case of any such reimbursement or payment,
          that such Master Servicer's or Servicer's right thereto shall be
          prior to the rights of the Certificateholders;

              (iv) in the event it has elected not to pay itself the
          Master Servicing Fee out of any Mortgagor payment on account of
          interest or other recovery with respect to a particular Mortgage
          Loan prior to the deposit of such Mortgagor payment or recovery in
          the Collection Account, to pay to itself the Master Servicing Fee
          for each Distribution Date and any unpaid Master Servicing Fees for
          prior Distribution Dates, as reduced pursuant to Section 5.05, from
          any Mortgagor payment as to interest or such other recovery with
          respect to that Mortgage Loan, as is permitted by this Agreement;

              (v) to reimburse itself or any Servicer for expenses incurred
          by and recoverable by or reimbursable to it or such Servicer
          pursuant to Section 9.04, 9.06, 9.16 or 9.22(a) or pursuant to the
          applicable Servicing Agreement, and to reimburse itself for any
          expenses reimbursable to it pursuant to Section 10.01(c);

             (vi) to pay to the applicable Person, with respect to each
          Mortgage Loan or REO Property acquired in respect thereof that has
          been repurchased by such Person pursuant to this Agreement, all
          amounts received thereon and not distributed on the date on which
          the related repurchase was effected;

            (vii) subject to Section 5.04, to pay to itself income earned
          on the investment of funds deposited in the Collection Account;

           (viii) to make payments to the Trustee for deposit into the
          Certificate Account in the amounts and in the manner provided for in
          Section 4.04;

             (ix) to make distributions of the Retained Interest to the
          Retained Interest Holder on each Distribution Date (other than any
          Retained Interest not deposited into the Collection Account in
          accordance with Section 4.01(d)(iii));

              (x) to make payment to itself, the Trustee and others pursuant
          to any provision of this Agreement;

             (xi) to withdraw funds deposited in error in the Collection
          Account;

            (xii) to clear and terminate any Collection Account pursuant to
          Section 7.02;

           (xiii) to reimburse a successor Master Servicer (solely in its
          capacity as successor Master Servicer), for any fee or advance
          occasioned by a termination of the Master Servicer, and the
          assumption of such duties by the Trustee or a successor Master
          Servicer appointed by the Trustee pursuant to Section 6.14, in each
          case to the extent not reimbursed by the terminated Master Servicer,
          it being understood, in the case of any such reimbursement or
          payment, that the right of the Master Servicer or the Trustee
          thereto shall be prior to the rights of the Certificateholders; and

            (xiv) to reimburse any Servicer for such amounts as are due
          thereto under the applicable Servicing Agreement and have not been
          retained by or paid to such Servicer to the extent provided in such
          Servicing Agreement.

         Each Servicer shall be entitled to retain as additional servicing
compensation any Prepayment Penalty Amounts.

         In connection with withdrawals pursuant to subclauses (i), (iii),
(iv) and (vi) above, the Master Servicer's or Servicer's entitlement thereto
is limited to collections or other recoveries on the related Mortgage Loan.
The Master Servicer shall therefore keep and maintain a separate accounting
for each Mortgage Loan it master services for the purpose of justifying any
withdrawal from the Collection Account it maintains pursuant to such subclause
(i), (iii), (iv) and (vi).

         Section 4.03. Reports to Certificateholders. (a) On each Distribution
Date, the Trustee shall deliver or cause to be delivered by first class mail
to each Certificateholder a written report setting forth the following
information (on the basis of Mortgage Loan level information obtained from the
applicable Servicer):

              (i)  the aggregate amount of the distribution to be made
          on such Distribution Date to the Holders of each Class of
          Certificates, other than any Class of Notional Certificates, to the
          extent applicable, allocable to principal on the Mortgage Loans,
          including Liquidation Proceeds and Insurance Proceeds, stating
          separately the amount attributable to scheduled principal payments
          and unscheduled payments in the nature of principal;

             (ii)  the aggregate amount of the distribution to be made on

related REO Property that has been provided to the Master Servicer by each
Servicer, and the Master Servicer shall not be obligated to verify, recompute,
reconcile or recalculate any such information or data. The Trustee shall be

data.

         Upon request, the Trustee shall also deliver or cause to be delivered

Certificateholder that is a savings and loan, bank or insurance company, which
request, if received by the Trustee, will be promptly forwarded to the Master
Servicer, the Master Servicer shall provide, or cause to be provided, (or, to
the extent that such information or documentation is not required to be
provided by a Servicer under the applicable Servicing Agreement, shall use
reasonable efforts to obtain such information and documentation from such
Servicer, and provide) to such Certificateholder such reports and access to
information and documentation regarding the Mortgage Loans as such
Certificateholder may reasonably deem necessary to comply with applicable
regulations of the Office of Thrift Supervision or its successor or other
regulatory authorities with respect to investment in the Certificates;

by such Certificateholder for such Master Servicer's actual expenses incurred
in providing such reports and access.

         (c) Within 90 days, or such shorter period as may be required by

Certificateholder of record, and make available to Certificate Owners
(identified as such by the Clearing Agency) in accordance with applicable
regulations, a report summarizing the items provided to Certificateholders
pursuant to Section 4.03(a) on an annual basis as may be required to enable
such Holders to prepare their federal income tax returns. Such information
shall include the amount of original issue discount accrued on each Class of
Certificates and information regarding the expenses of the Trust Fund. The
Master Servicer shall provide the Trustee with such information as is
necessary for the Trustee to prepare such reports.

         (d) Notwithstanding the foregoing, upon receipt of written notice
from the Depositor that each Class of Subordinate Certificates has been sold
to an unaffiliated third party, the Trustee shall make the reports required by
this Section 4.03 available to such Holders of the Subordinate Certificates.

         Section 4.04. Certificate Account. (a) The Trustee shall establish
and maintain in its name, as trustee, a trust account (the "Certificate
Account"), to be held in trust for the benefit of the Certificateholders until
disbursed pursuant to the terms of this Agreement. The Certificate Account
shall be an Eligible Account. If the existing Certificate Account ceases to be
an Eligible Account, the Trustee shall establish a new Certificate Account
that is an Eligible Account within 20 Business Days and transfer all funds on
deposit in such existing Certificate Account into such new Certificate
Account. The Certificate Account shall relate solely to the Certificates
issued hereunder and funds in the Certificate Account shall be held separate
and apart from and shall not be commingled with any other monies including,
without limitation, other monies of the Trustee held under this Agreement.

         (b) The Trustee shall cause to be deposited into the Certificate
Account on the day on which, or, if such day is not a Business Day, the
Business Day immediately following the day on which, any monies are remitted
by the Master Servicer to the Trustee all such amounts. The Trustee shall make
withdrawals from the Certificate Account only for the following purposes:

             (i)   to withdraw amounts deposited in the Certificate Account in
          error;

            (ii)   to pay itself any investment income earned with
          respect to funds in the Certificate Account invested in Eligible
          Investments as set forth in subsection (c) below, and to make
          payments to itself prior to making distributions pursuant to Section
          5.02 for any expenses or other indemnification owing to the Trustee
          and others pursuant to any provision of this Agreement;

           (iii)   to make payments of the Master Servicing Fee (to the
          extent not already withheld or withdrawn from the Collection Account
          by the Master Servicer) to the Master Servicer;

            (iv)   to make distributions to the Certificateholders pursuant
          to Article V; and

             (v)   to clear and terminate the Certificate Account pursuant to
          Section 7.02.

         (c) The Trustee may invest, or cause to be invested, funds held in
the Certificate Account, which funds, if invested, shall be invested in
Eligible Investments (which may be obligations of the Trustee). All such
investments must mature no later than the next Distribution Date, and shall
not be sold or disposed of prior to their maturity. All such Eligible
Investments will be made in the name of the Trustee (in its capacity as such)
or its nominee. All income and gain realized from any such investment shall be
compensation for the Trustee and shall be subject to its withdrawal on order
from time to time. The amount of any losses incurred in respect of any such
investments shall be paid by the Trustee for deposit in the Certificate
Account out of its own funds, without any right of reimbursement therefor,
immediately as realized. Funds held in the Certificate Account that are not
invested shall be held in cash.

         Section 4.05. [Reserved].

         Section 4.06. Certain Provisions With Respect to the Participations.
If the Trustee shall not have received a payment with respect to any
Participation by the date on which such payment was due and payable pursuant
to the terms thereof, the Trustee shall make demand upon the Participation
Master Servicer for immediate payment, and may, and at the direction of a
majority (by Voting Interests) of the Certificateholders shall, take any
available legal action, including the prosecution of any claims in connection
therewith. The Depositor shall cooperate with the Trustee in connection with
any such demand or action to the extent reasonably requested by the Trustee.
The reasonable legal fees and expenses incurred by the Trustee in connection
with the prosecution of any such legal action shall be reimbursable to the
Trustee from the Trust Fund.

                                  Article V

                   DISTRIBUTIONS TO HOLDERS OF CERTIFICATES

         Section 5.01. Distributions Generally. (a) Subject to Section 7.01
with respect to the final distribution on the Certificates, on each
Distribution Date the Trustee or the Paying Agent shall make distributions in
accordance with this Article V. Such distributions shall be made by check
mailed to each Certificateholder's address as it appears on the Certificate
Register of the Certificate Registrar (which shall initially be the Trustee)
or, upon written request made to the Trustee at least three Business Days
prior to the related Distribution Date to any Certificateholder owning an
aggregate initial Certificate Principal Amount of at least $2,500,000, or, in
the case of the Notional Certificates and Principal Only Certificates, a
Percentage Interest of 100%, by wire transfer in immediately available funds
to an account specified in the request and at the expense of such
Certificateholder; provided, however, that the final distribution in respect
of any Certificate shall be made only upon presentation and surrender of such
Certificate at the Corporate Trust Office. Wire transfers will be made at the
expense of the Holder requesting such wire transfer by deducting a wire
transfer fee from the related distribution. Notwithstanding such final payment
of principal of any of the Certificates, each Residual Certificate will remain
outstanding until the termination of each REMIC and the payment in full of all
other amounts due with respect to the Residual Certificate and at such time
such final payment in retirement of the Residual Certificate will be made only
upon presentation and surrender of such Certificate at the Corporate Trust
Office of the Trustee or at the office of its designated presenting agent in
New York City. If any payment required to be made on the Certificates is to be
made on a day that is not a Business Day, then such payment will be made on
the next succeeding Business Day.

         (b) All distributions or allocations made with respect to
Certificateholders within each Class on each Distribution Date shall be
allocated among the outstanding Certificates in such Class equally in
proportion to their respective initial Certificate Principal Amounts (or
initial Notional Amounts).

         Section 5.02. Distributions from the Certificate Account. (a) On each
Distribution Date, the Trustee (or the Paying Agent on behalf of the Trustee)
shall withdraw from the Certificate Account the Available Distribution Amount,
and shall distribute such amount to itself (in the case of clause (i)) and to
the Holders of record of each Class of Certificates, in the following order of
priority:

                    (i)   to the Trustee, the Trustee Fee for such Distribution
                  Date;

                   (ii)   to each Class of Senior Certificates (other than any
                  Class of Principal Only Certificates on or prior to the
                  Distribution Date in November 2005), the Accrued Certificate
                  Interest thereon for such Distribution Date, as reduced by
                  such Class's allocable share of any Net Prepayment Interest
                  Shortfalls for such Distribution Date; provided, however,
                  that any shortfall in available amounts shall be allocated
                  among the Classes of Certificates in proportion to the
                  amount of Accrued Certificate Interest (as so reduced) that
                  would otherwise be distributable thereon;

                  (iii)   to each Class of Senior Certificates (other than any
                  Class of Principal Only Certificates on or prior to the
                  Distribution Date in November 2005), any related Interest
                  Shortfall for such Distribution Date; provided, however,
                  that any shortfall in available amounts shall be allocated
                  among the Classes of Certificates in proportion to the
                  Interest Shortfall for each such Class on such Distribution
                  Date;

                    (iv)  to the Class A1, Class A2, Class A3, Class A6 and

                        Accrued Certificate Interest thereon for such
                        Distribution Date, as reduced by such Class's
                        allocable share of any Net Prepayment Interest
                        Shortfalls for such Distribution Date;

                           (N) to the Class B5 Certificates, any Interest
                        Shortfall for such Class on such Distribution Date;

                           (O) to the Class B5 Certificates, in
                        reduction of the Certificate Principal Amount thereof,
                        such Class's Subordinate Class Percentage of the
                        Subordinate Principal Distribution Amount for such
                        Distribution Date, except as provided in Section
                        5.02(c), until the Class Principal Balance thereof has
                        been reduced to zero;

                           (P) to the Class B6 Certificates, the
                        Accrued Certificate Interest thereon for such
                        Distribution Date, as reduced by such Class's
                        allocable share of any Net Prepayment Interest
                        Shortfalls for such Distribution Date;

                           (Q) to the Class B6 Certificates, any Interest
                        Shortfall for such Class on such Distribution Date;
                        and

                           (R) to the Class B6 Certificates, in
                        reduction of the Certificate Principal Amount thereof,
                        such Class's Subordinate Class Percentage of the
                        Subordinate Principal Distribution Amount for such
                        Distribution Date, except as provided in Section
                        5.02(c), until the Certificate Principal Balance
                        thereof has been reduced to zero.

         (b) Net Prepayment Interest Shortfalls shall be allocated
among the Certificates (other than any related Principal Only Certificates on
or prior to the Distribution Date in November 2005) pro rata based on the
Accrued Certificate Interest otherwise distributable thereon.

         (c) (i) If on any Distribution Date the Credit Support
Percentage for the Class B1 Certificates is less than the Original Credit
Support Percentage for such Class, then, notwithstanding anything to the
contrary in Section 5.02(a), no distribution of amounts described in clauses
(ii) and (iii) of the definition of Subordinate Principal Distribution Amount
will be made in respect of the Class B2, Class B3, Class B4, Class B5 or Class

the Credit Support Percentage for the Class B2 Certificates is less than the
Original Credit Support Percentage for such Class, then, notwithstanding

described in clauses (ii) and (iii) of the definition of Subordinate Principal
Distribution Amount will be made in respect of the Class B3, Class B4, Class
B5 or Class B6 Certificates on such Distribution Date. (iii) If on any
Distribution Date the Credit Support Percentage for the Class B3 Certificates
is less than the Original Credit Support Percentage for such Class, then,
notwithstanding anything to the contrary in Section 5.02(a), no distribution

Subordinate Principal Distribution Amount will be made in respect of the Class
B6 Certificates on such Distribution Date.

         Any amount not distributed in respect of any Class on any
Distribution Date pursuant to the immediately preceding paragraph will be
allocated among the remaining Subordinate Classes in proportion to their
respective Certificate Principal Amounts.

         (d) On each Distribution Date, the Trustee shall distribute to the
Holder of the Class R Certificate any amounts remaining in the Upper Tier
REMIC for such Distribution Date after application of all amounts described in
paragraph (a) of this Section 5.02. Any distributions pursuant to this
paragraph (d) shall not reduce the Class Principal Amount of the Class R
Certificate.

         Section 5.03. Allocation of Realized Losses. (a) On any Distribution
Date, (x) the applicable AP Percentage of the principal portion of each
Realized Loss in respect of a Mortgage Loan will be allocated to the Class A6
Certificates until the Class Principal Amount thereof has been reduced to
zero; and (y) the applicable Non-AP Percentage of the principal portion of
each Realized Loss (other than any Excess Loss) in respect of a Mortgage Loan
shall be allocated in the following order of priority:

                         first, to the Class B6 Certificates, until the Class
                    Principal Amount thereof has been reduced to zero;

                         second, to the Class B5 Certificates, until the Class
                    Principal Amount thereof has been reduced to zero;

                         third, to the Class B4 Certificates, until the Class
                    Principal Amount thereof has been reduced to zero;

                         fourth, to the Class B3 Certificates, until the Class
                    Principal Amount thereof has been reduced to zero;

                         fifth, to the Class B2 Certificates, until the Class
                    Principal Amount thereof has been reduced to zero;

                         sixth, to the Class B1 Certificates, until the Class
                    Principal Amount thereof has been reduced to zero; and

                         seventh, to the Classes of Senior Certificates, pro
                    rata, in accordance with their Class Principal Amounts;
                    provided, that any such loss allocated to any Class of
                    Accrual Certificates shall be allocated (subject to
                    Section 5.03(c)) on the basis of the lesser of (x) the
                    Class Principal Amount thereof immediately prior to the
                    applicable Distribution Date and (y) the Class Principal
                    Amount thereof on the Closing Date (as reduced by any
                    Realized Losses previously allocated thereto).

         (b) With respect to any Distribution Date, the applicable
Non-AP Percentage of the principal portion of any Excess Loss in respect of a
Mortgage Loan shall be allocated, pro rata, to all the Certificates (other
than the Class A6 Certificates) on the basis of their respective Class
Principal Amounts; provided, that any such loss allocated to any Class of
Accrual Certificates (and any Accrual Component) shall be allocated (subject
to Section 5.03(c)) on the basis of the lesser of (x) the Class Principal
Amount thereof immediately prior to the applicable Distribution Date and (y)
the Class Principal Amount thereof on the Closing Date (as reduced by any
Realized Losses previously allocated thereto).

         (c) Any Realized Losses allocated to a Class of Certificates pursuant
to Section 5.03(a) or (b) shall be allocated among the Certificates of such
Class in proportion to their respective Certificate Principal Amounts. Any
allocation of Realized Losses pursuant to this paragraph (c) shall be
accomplished by reducing the Certificate Principal Amount of the related
Certificates on the related Distribution Date in accordance with Section
5.03(d).

         (d) Realized Losses allocated in accordance with this Section 5.03
shall be allocated on the Distribution Date in the month following the month
in which such loss was incurred and, in the case of the principal portion
thereof, after giving effect to distributions made on such Distribution Date,
except that the aggregate amount of Realized Losses to be allocated to the
Principal Only Certificates on such Distribution Date will be taken into
account in determining distributions in respect of any related Class AP
Deferred Amount for such date.

         (e) On each Distribution Date, the Subordinate Certificate Writedown
Amount for such date shall effect a corresponding reduction in the Certificate
Principal Amount of the lowest ranking Class of outstanding Subordinate
Certificates, which reduction shall occur on such Distribution Date after
giving effect to distributions made on such Distribution Date.

         (f) In the event that there is a recovery of an amount in respect of
principal of a Mortgage Loan, which amount had previously been allocated as a
Realized Loss to one or more Classes of Certificates, each outstanding Class
to which any portion of such Realized Loss had previously been allocated shall
be entitled to receive, on the Distribution Date in the month following the
month in which such recovery is received, its pro rata share (based on the
Class Principal Amount thereof) of such recovery, up to the amount of the
portion of such Realized Loss previously allocated to such Class. In the event
that the total amount of such recovery exceeds the amount of Realized Loss
allocated to the outstanding Classes in accordance with the preceding
provisions, each outstanding Class of Certificates shall be entitled to
receive its pro rata share of the amount of such excess, up to the amount of
any unrecovered Realized Loss previously allocated to such Class. Any such
recovery allocated to a Class of Certificates shall not further reduce the
Certificate Principal Amount of such Certificate. Any such amounts not
otherwise allocated to any Class of Certificates, pursuant to this subsection
shall be treated as Principal Prepayments for purposes of this Agreement.

         Section 5.04. Advances by Master Servicer and Trustee. (a) Advances
shall be made in respect of each Deposit Date as provided herein. If, on any
Determination Date, the Master Servicer determines that any Scheduled Payments
due during the related Due Period (other than Balloon Payments) have not been
received, the Master Servicer shall, or shall cause the applicable Servicer
to, advance such amount, less an amount, if any, to be set forth in an
Officer's Certificate to be delivered to the Trustee on such Determination
Date, which if advanced the Master Servicer or such Servicer has determined
would not be recoverable from amounts received with respect to such Mortgage
Loan, including late payments, Liquidation Proceeds, Insurance Proceeds or
otherwise. If the Master Servicer determines that an Advance is required, it
shall on the Deposit Date immediately following such Determination Date either
(i) remit to the Trustee from its own funds (or funds advanced by the
applicable Servicer) for deposit in the Certificate Account immediately
available funds in an amount equal to such Advance, (ii) cause to be made an
appropriate entry in the records of the Collection Account that funds in such
account being held for future distribution or withdrawal have been, as
permitted by this Section 5.04, used by the Master Servicer to make such
Advance, and remit such immediately available funds to the Trustee for deposit
in the Certificate Account or (iii) make Advances in the form of any
combination of clauses (i) and (ii) aggregating the amount of such Advance.
Any funds being held in the Collection Account for future distribution to
Certificateholders and so used shall be replaced by the Master Servicer from
its own funds by remittance to the Trustee for deposit in the Certificate
Account on or before any future Deposit Date to the extent that funds in the
Certificate Account on such Deposit Date shall be less than payments to
Certificateholders required to be made on the related Distribution Date. The
Master Servicer and each Servicer shall be entitled to be reimbursed from the
Collection Account for all Advances made by it as provided in Section 4.02.

         (b) In the event that the Master Servicer fails for any reason to
make an Advance required to be made pursuant to Section 5.04 on or before the
Deposit Date, the Trustee, solely in its capacity as successor Master Servicer
pursuant to Section 6.14, shall, on or before the related Distribution Date,
deposit in the Certificate Account an amount equal to the excess of (a)
Advances required to be made by the Master Servicer or any Servicer that would
have been deposited in such Certificate Account over (b) the amount of any
Advance made by the Master Servicer or such Servicer with respect to such
Distribution Date; provided, however, that the Trustee shall be required to
make such Advance only if it is not prohibited by law from doing so and it has
determined that such Advance would be recoverable from amounts to be received
with respect to such Mortgage Loan, including late payments, Liquidation
Proceeds, Insurance Proceeds, or otherwise. The Trustee shall be entitled to
be reimbursed from the Certificate Account for Advances made by it pursuant to
this Section 5.04 as if it were the Master Servicer.

         Section 5.05. Compensating Interest Payments. The amount of the
Aggregate Master Servicing Compensation payable to the Master Servicer in
respect of any Distribution Date shall be reduced by the amount of any
Compensating Interest Payment for such Distribution Date, but only to the
extent such Compensating Interest Payment is not actually made by the
applicable Servicer on the applicable Remittance Date. Such amount shall not
be treated as an Advance and shall not be reimbursable to the Master Servicer.

                                  Article VI

                   CONCERNING THE TRUSTEE; EVENTS OF DEFAULT

         Section 6.01. Duties of Trustee. (a) The Trustee, except during the
continuance of an Event of Default (of which a Responsible Officer of the
Trustee shall have actual knowledge), undertakes to perform such duties and
only such duties as are specifically set forth in this Agreement. Any
permissive right of the Trustee provided for in this Agreement shall not be
construed as a duty of the Trustee. If an Event of Default (of which a
Responsible Officer of the Trustee shall have actual knowledge) has occurred
and has not otherwise been cured or waived, the Trustee shall exercise such of
the rights and powers vested in it by this Agreement and use the same degree
of care and skill in their exercise as a prudent Person would exercise or use
under the circumstances in the conduct of such Person's own affairs unless the
Trustee is acting as Master Servicer, in which case it shall use the same
degree of care and skill as the Master Servicer hereunder.

         (b) The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments
furnished to the Trustee which are specifically required to be furnished
pursuant to any provision of this Agreement, shall examine them to determine
whether they are in the form required by this Agreement; provided, however,
that the Trustee shall not be responsible for the accuracy or content of any
such resolution, certificate, statement, opinion, report, document, order or
other instrument furnished by the Master Servicer, to the Trustee pursuant to
this Agreement, and shall not be required to recalculate or verify any
numerical information furnished to the Trustee pursuant to this Agreement.

         (c) The Trustee shall not have any liability arising out of or in
connection with this Agreement, except for its negligence or willful
misconduct. 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 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 direction of Holders of
          Certificates as provided in Section 6.19 hereof;

              (ii) For all purposes under this Agreement, the Trustee shall
          not be deemed to have notice of any Event of Default (other than
          resulting from a failure by the Master Servicer (i) to remit funds
          (or to make Advances) or (ii) to furnish information to the Trustee
          when required to do so) unless a Responsible Officer of the Trustee
          has actual 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, and such notice references the Holders of
          the Certificates and this Agreement; and

             (iii) No provision of this Agreement shall require the Trustee
          to expend or risk its own funds or otherwise incur any financial
          liability in the performance of any of its duties hereunder, or in
          the exercise of any of its rights or powers, if it shall have
          reasonable grounds for believing that repayment of such funds or
          adequate indemnity against such risk or liability is not reasonably
          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 the Master 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.

         (d) The Trustee shall have no duty hereunder with respect to any
complaint, claim, demand, notice or other document it may receive or which may
be alleged to have been delivered to or served upon it by the parties as a
consequence of the assignment of any Mortgage Loan hereunder; provided,
however, that the Trustee shall use its best efforts to remit to the Master
Servicer upon receipt any such complaint, claim, demand, notice or other
document (i) which is delivered to the Corporate Trust Office of the Trustee,
(ii) of which a Responsible Officer has actual knowledge, and (iii) which
contains information sufficient to permit the Trustee to make a determination
that the real property to which such document relates is a Mortgaged Property.

         (e) 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 direction of Certificateholders of any Class holding
Certificates which evidence, as to such Class, Percentage Interests
aggregating not less than 25% as 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.

         (f) Subject to Section 4.04, the Trustee shall not be held liable by
reason of any insufficiency in any account (including without limitation the
Collection Account) held by or on behalf of the Trustee resulting from any
investment loss on any Eligible Investment included therein (except to the
extent that the Trustee is the obligor and has defaulted thereon).

         (g) Except as otherwise provided herein, the Trustee shall have no
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 or filing or depositing or to any re-recording, re-filing or
re-depositing of any thereof, (B) to see to any insurance, (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 Fund other than from funds available in the
Collection Account or the Certificate Account, or (D) to confirm or verify the
contents of any reports or certificates of the Master Servicer delivered to
the Trustee pursuant to this Agreement believed by the Trustee to be genuine
and to have been signed or presented by the proper party or parties.

         (h) The Trustee shall not be liable in its individual capacity for an
error of judgment made in good faith by a Responsible Officer or other
officers of the Trustee, unless it shall be proved that the Trustee was
negligent in ascertaining the pertinent facts.

         (i) Notwithstanding anything in this Agreement to the contrary, the
Trustee shall not be liable for special, indirect or consequential losses or
damages of any kind whatsoever (including, but not limited to, lost profits),
even if the Trustee has been advised of the likelihood of such loss or damage
and regardless of the form of action.

         Section 6.02. Certain Matters Affecting the Trustee. Except as
otherwise provided in Section 6.01:

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

               (ii) The Trustee may consult with counsel and any advice of its
          counsel or 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 personally liable for any action
          taken, suffered or omitted by it in good faith and reasonably
          believed by it to be authorized or within the discretion or rights
          or powers conferred upon it by this Agreement;

               (iv) Unless an Event of Default shall have occurred and be
          continuing, the Trustee shall not be bound to make any investigation
          into the facts or matters stated in any resolution, certificate,
          statement, instrument, opinion, report, notice, request, consent,
          order, approval, bond or other paper or document (provided the same
          appears regular on its face), unless requested in writing to do so
          by Holders of at least a majority in Class Principal Amount (or
          Class Notional Amount) of each Class of Certificates; 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 the security
          afforded to it by the terms of this Agreement, the Trustee may
          require reasonable indemnity against such expense or liability or
          payment of such estimated expenses as a condition to proceeding. The
          reasonable expense thereof shall be paid by the Holders requesting
          such investigation;

               (v) The Trustee may execute any of the trusts or powers
          hereunder or perform any duties hereunder either directly or by or
          through agents, custodians, or attorneys, which agents, custodians
          or attorneys shall have any and all of the rights, powers, duties
          and obligations of the Trustee conferred on them by such appointment
          provided that the Trustee shall continue to be responsible for its
          duties and obligations hereunder to the extent provided herein, and
          provided further that the Trustee shall not be responsible for any
          misconduct or negligence on the part of any such agent or attorney
          appointed with due care by the Trustee;

               (vi) The Trustee shall be under no 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, in each case at the request, order or direction of any of
          the Certificateholders pursuant to the provisions of this Agreement,
          unless such Certificateholders shall have offered to the Trustee
          reasonable security or indemnity against the costs, expenses and
          liabilities which may be incurred therein or thereby;

               (vii) The right of the Trustee to perform any discretionary act
          enumerated in this Agreement shall not be construed as a duty, and
          the Trustee shall not be answerable for other than its negligence or
          willful misconduct in the performance of such act; and

               (viii) The Trustee shall not be required to give any bond or
          surety in respect of the execution of the Trust Fund created hereby
          or the powers granted hereunder.

         Section 6.03. Trustee Not Liable for Certificates. The Trustee makes
no representations as to the validity or sufficiency of this Agreement or of
the Certificates (other than the certificate of authentication on the
Certificates) or of any Mortgage Loan, or related document save that the
Trustee represents that, assuming due execution and delivery by the other
parties hereto, this Agreement has been duly authorized, executed and
delivered by it and constitutes its valid and binding obligation, enforceable
against it in accordance with its terms except that such enforceability may be
subject to (A) applicable bankruptcy and insolvency laws and other similar
laws affecting the enforcement of the rights of creditors generally, and (B)
general principles of equity regardless of whether such enforcement is
considered in a proceeding in equity or at law. The Trustee shall not be
accountable for the use or application by the Depositor of funds paid to the
Depositor in consideration of the assignment of the Mortgage Loans to the
Trust Fund by the Depositor or for the use or application of any funds
deposited into the Collection Account, the Certificate Account, any Escrow
Account or any other fund or account maintained with respect to the
Certificates. The Trustee shall not be responsible for the legality or
validity of this Agreement or the validity, priority, perfection or
sufficiency of the security for the Certificates issued or intended to be
issued hereunder. Except as otherwise provided herein, the Trustee shall have
no responsibility for filing any financing or continuation statement in any
public office at any time or to otherwise perfect or maintain the perfection
of any security interest or lien granted to it hereunder or to record this

         Section 6.05. Eligibility Requirements for Trustee. The Trustee
hereunder shall at all times be (i) an institution insured by the FDIC and
(ii) a corporation or national banking association, organized and doing
business under the laws of any State or the United States of America,

combined capital and surplus of not less than $50,000,000 and subject to
supervision or examination by federal or state authority. If such corporation
or national banking association publishes reports of condition at least
annually, pursuant to law or to the requirements of the aforesaid supervising
or examining authority, then, for the purposes of this Section, the combined
capital and surplus of such corporation or national banking association shall
be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. In case at any time the Trustee shall
cease to be eligible in accordance with provisions of this Section, the
Trustee shall resign immediately in the manner and with the effect specified
in Section 6.06.

         Section 6.06. Resignation and Removal of Trustee. (a) The Trustee may
at any time resign and be discharged from the trust hereby created by giving
written notice thereof to the Depositor and the Master Servicer. Upon
receiving such notice of resignation, the Depositor will promptly appoint a
successor trustee by written instrument, one copy of which instrument shall be
delivered to the resigning Trustee, one copy to the successor trustee and one
copy to the Master Servicer. If no successor trustee shall have been so
appointed and shall have 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.

         (b) If at any time (i) the Trustee shall cease to be eligible in
accordance with the provisions of Section 6.05 and shall fail to resign after
written request therefor by the Depositor, (ii) the Trustee shall become
incapable of acting, 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, (iii)
a tax is imposed or threatened with respect to the Trust Fund by any state in
which the Trustee or the Trust Fund held by the Trustee is located, or (iv)
the continued use of the Trustee would result in a downgrading of the rating
by the Rating Agencies of any Class of Certificates with a rating, then the
Depositor shall remove the Trustee and appoint a successor trustee by written
instrument, one copy of which instrument shall be delivered to the Trustee so
removed, one copy to the successor trustee and one copy to the Master
Servicer.

         (c) The Holders of more than 50% of the Class Principal Amount (or
Class Notional Amount) of each Class of Certificates may at any time upon 30
days' written notice to the Trustee and to the Depositor remove the Trustee by
such written instrument, signed by such Holders or their attorney-in-fact duly
authorized, one copy of which instrument shall be delivered to the Depositor,
one copy to the Trustee so removed and one copy to the Master Servicer; the
Depositor shall thereupon use its best efforts to appoint a mutually
acceptable successor trustee in accordance with this Section.

         (d) Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 6.07.

         Section 6.07. Successor Trustee. (a) Any successor trustee appointed
as provided in Section 6.06 shall execute, acknowledge and deliver to the
Depositor, 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 herein. The predecessor
trustee shall deliver to the successor trustee all Mortgage Files and
documents and statements related to each Mortgage File held by it hereunder,
and shall duly assign, transfer, deliver and pay over to the successor trustee
the entire Trust Fund, together with all necessary instruments of transfer and
assignment or other documents properly executed necessary to effect such
transfer and such of the record or copies thereof maintained by the
predecessor trustee in the administration hereof as may be requested by the
successor trustee and shall thereupon be discharged from all duties and
responsibilities under this Agreement. In addition, the Master Servicer and
the predecessor trustee shall execute and deliver such other instruments and
do such other things as may reasonably be required to more fully and certainly
vest and confirm in the successor trustee all such rights, powers, duties and
obligations.

         (b) No successor trustee shall accept appointment as provided in this
Section unless at the time of such appointment such successor trustee shall be
eligible under the provisions of Section 6.05.

         (c) Upon acceptance of appointment by a successor trustee as provided
in this Section, the Master Servicer shall mail notice of the succession of
such trustee hereunder to all Holders of Certificates at their addresses as
shown in the Certificate Register and to the Rating Agencies. The expenses of
such mailing shall be borne by the Master Servicer.

         Section 6.08. Merger or Consolidation of Trustee. Any Person into
which the Trustee may be merged or with which it may be consolidated, or any
Person resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any Persons succeeding to the business of the
Trustee, shall be the successor to the Trustee hereunder, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, anything herein to the contrary notwithstanding, provided that
such Person shall be eligible under the provisions of Section 6.05.

         Section 6.09. Appointment of Co-Trustee, Separate Trustee or
Custodian. (a) Notwithstanding any other provisions hereof, at any time, the
Trustee, the Depositor or the Certificateholders evidencing more than 50% of
the Class Principal Amount (or Class Notional Amount) of each Class of
Certificates shall each have the power from time to time to appoint one or
more Persons to act either as co-trustees jointly with the Trustee, or as
separate trustees, or as custodians, for the purpose of holding title to,
foreclosing or otherwise taking action with respect to any Mortgage Loan
outside the state where the Trustee has its principal place of business where
such separate trustee or co-trustee is necessary or advisable (or the Trustee
has been advised by the Master Servicer that such separate trustee or
co-trustee is necessary or advisable) under the laws of any state in which a
property securing a Mortgage Loan is located or for the purpose of otherwise
conforming to any legal requirement, restriction or condition in any state in
which a property securing a Mortgage Loan is located or in any state in which
any portion of the Trust Fund is located. The separate Trustees, co-trustees,
or custodians so appointed shall be trustees or custodians for the benefit of
all the Certificateholders and shall have such powers, rights and remedies as
shall be specified in the instrument of appointment; provided, however, that
no such appointment shall, or shall be deemed to, constitute the appointee an
agent of the Trustee. The obligation of the Trustee to make Advances pursuant
to Section 5.04 and 6.14 hereof shall not be affected or assigned by the
appointment of a co-trustee.

         (b) Every separate trustee, co-trustee, and custodian shall, to the
extent permitted by law, be appointed and act subject to the following
provisions and conditions:

               (i) all powers, duties, obligations and rights conferred upon
          the Trustee in respect of the receipt, custody and payment of moneys
          shall be exercised solely by the Trustee;

               (ii) all other rights, powers, duties and obligations conferred
          or imposed upon the Trustee shall be conferred or imposed upon and
          exercised or performed by the Trustee and such separate trustee,
          co-trustee, or custodian jointly, except to the extent that under
          any law of any jurisdiction in which any particular act or acts are
          to be performed 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 by such separate trustee, co-trustee, or custodian;

               (iii) no trustee or custodian hereunder shall be personally
          liable by reason of any act or omission of any other trustee or
          custodian hereunder; and

               (iv) the Trustee or the Certificateholders evidencing more than
          50% of the Aggregate Voting Interests of the Certificates may at any
          time accept the resignation of or remove any separate trustee,
          co-trustee or custodian, so appointed by it or them, if such
          resignation or removal does not violate the other terms of this
          Agreement.

         (c) Any notice, request or other writing given to the Trustee shall
be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee, co-trustee or custodian shall refer to this
Agreement and the conditions of this Article VI. 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.

         (d) Any separate trustee, co-trustee or custodian 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. The Trustee shall
not be responsible for any action or inaction of any separate trustee,
co-trustee or custodian. If any separate trustee, co-trustee or custodian
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.

         (e) No separate trustee, co-trustee or custodian hereunder shall be
required to meet the terms of eligibility as a successor trustee under Section
6.05 hereunder and no notice to Certificateholders of the appointment shall be
required under Section 6.07 hereof.

         (f) The Trustee agrees to instruct the co-trustees, if any, to the
extent necessary to fulfill the Trustee's obligations hereunder.

         (g) The Trustee shall pay the reasonable compensation of the
co-trustees to the extent, and in accordance with the standards, specified in
Section 6.12 hereof (which compensation shall not reduce any compensation
payable to the Trustee under such Section).

         Section 6.10. Authenticating Agents. (a) The Trustee may appoint one
or more Authenticating Agents which shall be authorized to act on behalf of
the Trustee in authenticating 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 a corporation
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.

         (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 with 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 shall be entitled to
reasonable compensation for its services and, if paid by the Trustee, it shall
be a reimbursable expense pursuant to Section 6.12.

         Section 6.11. Indemnification of Trustee. The Trustee and its
directors, officers, employees and agents shall be entitled to indemnification
from the Trust Fund for any loss, liability or expense incurred in connection
with any legal proceeding and incurred without negligence or willful
misconduct on their part, arising out of, or in connection with, the
acceptance or administration of the trusts created hereunder, including the
costs and expenses of defending themselves against any claim in connection
with the exercise or performance of any of their powers or duties hereunder,
provided that:

               (i) with respect to any such claim, the Trustee shall have
          given the Depositor, the Master Servicer and the Holders written
          notice thereof promptly after the Trustee shall have knowledge
          thereof; provided, however, any reasonable delay by the Trustee to
          provide written notice to the Depositor, the Master Servicer and the
          Holders promptly after the Trustee shall have obtained knowledge of
          a claim shall not relieve the Trust Fund of its obligations to
          indemnify the Trustee under this Section 6.11;

               (ii) while maintaining control over its own defense, the
          Trustee shall cooperate and consult fully with the Depositor in
          preparing such defense; and

               (iii) notwithstanding anything to the contrary in this Section
          6.11, the Trust Fund shall not be liable for settlement of any such
          claim by the Trustee entered into without the prior consent of the
          Depositor, which consent shall not be unreasonably withheld.

         The provisions of this Section 6.11 shall survive any termination of
this Agreement and the resignation or removal of the Trustee and shall be
construed to include, but not be limited to any loss, liability or expense
under any environmental law.

         Section 6.12. Fees and Expenses of Trustee. The Trustee shall be
entitled to the Trustee Fee (which shall not be limited by any provision of
law in regard to the compensation of a trustee of an express trust), to the
extent provided herein, and in addition, the Trustee shall be entitled to
receive, and is authorized to pay to itself the amount of income or gain
earned from the investment of funds in the Certificate Account.

         Section 6.13. Collection of Monies. Except as otherwise expressly
provided in this Agreement, the Trustee may demand payment or delivery of, and
shall receive and collect, all money and other property payable to or
receivable by the Trustee pursuant to this Agreement. The Trustee shall hold
all such money and property received by it as part of the Trust Fund and shall
distribute it as provided in this Agreement. If the Trustee shall not have
timely received amounts to be remitted with respect to the Mortgage Loans from
the Master Servicer, the Trustee shall request the Master Servicer to make
such distribution as promptly as practicable or legally permitted. If the
Trustee shall subsequently receive any such amount, it may withdraw such
request.

         Section 6.14. Events of Default; Trustee To Act; Appointment of
Successor. (a) The occurrence of any one or more of the following events shall
constitute an "Event of Default":

               (i) Any failure by the Master Servicer to furnish the Trustee
          the Mortgage Loan data sufficient to prepare the reports described
          in Section 4.03(a) which continues unremedied for a period of one
          Business Day after the date upon which written notice of such
          failure shall have been given to such Master Servicer by the Trustee
          or to such Master Servicer and the Trustee by the Holders of not
          less than 25% of the Class Principal Amount (or Class Notional
          Amount) of each Class of Certificates affected thereby; or

               (ii) Any failure on the part of the Master Servicer duly to
          observe or perform in any material respect any other of the
          covenants or agreements on the part of such Master Servicer
          contained in this Agreement which continues unremedied for a period
          of 30 days (or 15 days, in the case of a failure to maintain any
          Insurance Policy required to be maintained pursuant to this
          Agreement) after the date on which written notice of such failure,
          requiring the same to be remedied, shall have been given to such
          Master Servicer by the Trustee, or to such Master Servicer and the
          Trustee by the Holders of not less than 25% of the Class Principal
          Amount (or Class Notional Amount) of each Class of Certificates
          affected thereby; or

               (iii) A decree or order of a court or agency or supervisory
          authority having jurisdiction for the appointment of a conservator
          or receiver or liquidator in any insolvency, readjustment of debt,
          marshalling of assets and liabilities or similar proceedings, or for
          the winding-up or liquidation of its affairs, shall have been
          entered against the Master Servicer, and such decree or order shall
          have remained in force undischarged or unstayed for a period of 60
          days or any Rating Agency reduces or withdraws or threatens to
          reduce or withdraw the rating of the Certificates because of the
          financial condition or loan servicing capability of such Master
          Servicer; or

               (iv) The Master Servicer shall consent to the appointment of a
          conservator or receiver or liquidator in any insolvency,
          readjustment of debt, marshalling of assets and liabilities,
          voluntary liquidation or similar proceedings of or relating to such
          Master Servicer or of or relating to all or substantially all of its
          property; or

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

               (vi) The Master Servicer shall be dissolved, or shall dispose
          of all or substantially all of its assets, or consolidate with or
          merge into another entity or shall permit another entity to
          consolidate or merge into it, such that the resulting entity does
          not meet the criteria for a successor servicer as specified in
          Section 9.27 hereof; or

               (vii) If a representation or warranty set forth in Section 9.14
          hereof shall prove to be incorrect as of the time made in any
          respect that materially and adversely affects the interests of the
          Certificateholders, and the circumstance or condition in respect of
          which such representation or warranty was incorrect shall not have
          been eliminated or cured within 60 days after the date on which
          written notice of such incorrect representation or warranty shall
          have been given to the Master Servicer by the Trustee, or to the
          Master Servicer and the Trustee by the Holders of not less than 25%
          of the Aggregate Certificate Principal Amount of each Class of
          Certificates; or

               (viii) A sale or pledge of the any of the rights of the Master
          Servicer hereunder or an assignment of this Agreement by the Master
          Servicer or a delegation of the rights or duties of the Master
          Servicer hereunder shall have occurred in any manner not otherwise
          permitted hereunder and without the prior written consent of the
          Trustee and Certificateholders holding more than 50% of the Class
          Principal Amount (or Class Notional Amount) of each Class of
          Certificates;

               (ix) Any Servicer at any time is not either an FNMA- or FHLMC-
          approved Seller/Servicer, and the Master Servicer has not terminated
          the rights and obligations of such Servicer under the applicable
          Servicing Agreement and replaced such Servicer with an FNMA- or
          FHLMC-approved servicer within 30 days of the absence of such
          approval; or

               (x) Any failure of the Master Servicer to remit to the Trustee
          any payment required to be made to the Trustee for the benefit of
          Certificateholders under the terms of this Agreement, including any
          Advance, on any Deposit Date.

         If an Event of Default described in clauses (i) through (ix) of this
Section 6.14 shall occur, then, in each and every case, subject to applicable
law, so long as any such Event of Default shall not have been remedied within
any period of time prescribed by this Section 6.14, the Trustee, by notice in
writing to the Master Servicer may, and shall, if so directed by
Certificateholders evidencing more than 50% of the Class Principal Amount (or
Class Notional Amount) of each Class of Certificates, terminate all of the
rights and obligations of the Master Servicer hereunder and in and to the
Mortgage Loans and the proceeds thereof. If an Event of Default described in
clause (x) of this Section 6.14 shall occur, then, in each and every case,
subject to applicable law, the Trustee, by notice in writing to the Master
Servicer, shall promptly terminate all of the rights and obligations of the
Master Servicer hereunder and in and to the Mortgage Loans and the proceeds
thereof. On or after the receipt by the Master Servicer of such written
notice, all authority and power of the Master Servicer, and only in its
capacity as Master Servicer under this Agreement, whether with respect to the
Mortgage Loans or otherwise, shall pass to and be vested in the Trustee
pursuant to and under the terms of this Agreement; and the Trustee is hereby
authorized and empowered to execute and deliver, on behalf of the defaulting
Master Servicer as attorney-in-fact or otherwise, any and all documents and
other instruments, and to do or accomplish all other acts or things necessary
or appropriate to effect the purposes of such notice of termination, whether
to complete the transfer and endorsement or assignment of the Mortgage Loans
and related documents or otherwise. The defaulting Master Servicer agrees to
cooperate with the Trustee in effecting the termination of the defaulting
Master Servicer's responsibilities and rights hereunder as Master Servicer
including, without limitation, notifying Mortgagors of the assignment of the
master servicing function and providing the Trustee or its designee all
documents and records in electronic or other form reasonably requested by it
to enable the Trustee or its designee to assume the defaulting Master
Servicer's functions hereunder and the transfer to the Trustee for
administration by it of all amounts which shall at the time be or should have
been deposited by the defaulting Master Servicer in the Collection Account
maintained by such defaulting Master Servicer and any other account or fund
maintained with respect to the Certificates or thereafter received with
respect to the Mortgage Loans. The Master Servicer being terminated shall bear
all costs of a master servicing transfer, including but not limited to those
of the Trustee reasonably allocable to specific employees and overhead, legal
fees and expenses, accounting and financial consulting fees and expenses, and
costs of amending the Agreement, if necessary.

         Notwithstanding the termination of its activities as Master Servicer,
each terminated Master Servicer shall continue to be entitled to reimbursement
to the extent provided in Section 4.02(i), (ii), (iii), (iv), (v), (vi),
(vii), (ix) and (xi) to the extent such reimbursement relates to the period
prior to such Master Servicer's termination.

         If any Event of Default shall occur of which a Responsible Officer of
the Trustee has actual knowledge, the Trustee shall promptly notify the Rating
Agencies of the nature and extent of such Event of Default. The Trustee shall
immediately give written notice to the Master Servicer upon such Master
Servicer's failure to remit funds on the Deposit Date.

         (b) On and after the time the Master Servicer receives a notice of
termination from the Trustee pursuant to Section 6.14(a) or the Trustee
receives the resignation of the Master Servicer evidenced by an Opinion of
Counsel pursuant to Section 9.29, the Trustee, unless another master servicer
shall have been appointed, shall be the successor in all respects to the
Master Servicer in its capacity as such under this Agreement and the
transactions set forth or provided for herein and shall have all the rights
and powers and be subject to all the responsibilities, duties and liabilities
relating thereto and arising thereafter placed on the Master Servicer
hereunder, including the obligation to make Advances; provided, however, that
any failure to perform such duties or responsibilities caused by the Master
Servicer's failure to provide information required by this Agreement shall not
be considered a default by the Trustee hereunder. In addition, the Trustee
shall have no responsibility for any act or omission of the Master Servicer
prior to the issuance of any notice of termination and shall have no liability
relating to the representations and warranties of the Master Servicer set
forth in Section 9.14. In the Trustee's capacity as such successor, the
Trustee shall have the same limitations on liability herein granted to the
Master Servicer. As compensation therefor, the Trustee shall be entitled to
receive all compensation payable to the Master Servicer under this Agreement,
including the Master Servicing Fee.

         (c) Notwithstanding the above, the Trustee may, if it shall be
unwilling to continue to so act, or shall, if it is unable to so act, appoint,
or petition a court of competent jurisdiction to appoint, any established
housing and home finance institution servicer, master servicer, servicing or
mortgage servicing institution having a net worth of not less than $15,000,000
and meeting such other standards for a successor master servicer as are set
forth in this Agreement, as the successor to such Master Servicer in the
assumption of all of the responsibilities, duties or liabilities of a master
servicer, like the Master Servicer. Any entity designated by the Trustee as a
successor master servicer may be an Affiliate of the Trustee; provided,
however, that, unless such Affiliate meets the net worth requirements and
other standards set forth herein for a successor master servicer, the Trustee,
in its individual capacity shall agree, at the time of such designation, to be
and remain liable to the Trust Fund for such Affiliate's actions and omissions
in performing its duties hereunder. In connection with such appointment and
assumption, the Trustee may make such arrangements for the compensation of
such successor out of payments on Mortgage Loans as it and such successor
shall agree; provided, however, that no such compensation shall be in excess
of that permitted to the Master Servicer hereunder. The Trustee and such
successor shall take such actions, consistent with this Agreement, as shall be
necessary to effectuate any such succession and may make other arrangements
with respect to the servicing to be conducted hereunder which are not
inconsistent herewith. The Master Servicer shall cooperate with the Trustee
and any successor master servicer in effecting the termination of the Master
Servicer's responsibilities and rights hereunder including, without
limitation, notifying Mortgagors of the assignment of the master servicing
functions and providing the Trustee and successor master servicer, as
applicable, all documents and records in electronic or other form reasonably
requested by it to enable it to assume the Master Servicer's functions
hereunder and the transfer to the Trustee or such successor master servicer,
as applicable, all amounts which shall at the time be or should have been
deposited by the Master Servicer in the Collection Account and any other
account or fund maintained with respect to the Certificates or thereafter be
received with respect to the Mortgage Loans. Neither the Trustee nor any other
successor master servicer shall be deemed to be in default hereunder by reason
of any failure to make, or any delay in making, any distribution hereunder or
any portion thereof caused by (i) the failure of the Master Servicer to
deliver, or any delay in delivering, cash, documents or records to it, (ii)
the failure of the Master Servicer to cooperate as required by this Agreement,
(iii) the failure of the Master Servicer to deliver the Mortgage Loan data to
the Trustee as required by this Agreement or (iv) restrictions imposed by any
regulatory authority having jurisdiction over the Master Servicer.

         Section 6.15. Additional Remedies of Trustee Upon Event of Default.
During the continuance of any Event of Default, so long as such Event of
Default shall not have been remedied, the Trustee, in addition to the rights
specified in Section 6.14, shall have the right, in its own name and as
trustee of an express trust, to take all actions now or hereafter existing at
law, in equity or by statute to enforce its rights and remedies and to protect
the interests, and enforce the rights and remedies, of the Certificateholders
(including the institution and prosecution of all judicial, administrative and
other proceedings and the filings of proofs of claim and debt in connection
therewith). Except as otherwise expressly provided in this Agreement, no
remedy provided for by this Agreement shall be exclusive of any other remedy,
and each and every remedy shall be cumulative and in addition to any other
remedy, and no delay or omission to exercise any right or remedy shall impair
any such right or remedy or shall be deemed to be a waiver of any Event of
Default.

         Section 6.16. Waiver of Defaults. 35% or more of the Aggregate Voting
Interests of Certificateholders may waive any default or Event of Default by
the Master Servicer in the performance of its obligations hereunder, except
that a default in the making of any required deposit to the Certificate
Account that would result in a failure of the Trustee to make any required
payment of principal of or interest on the Certificates may only be waived
with the consent of 100% of the affected Certificateholders. Upon any such
waiver of a past default, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been remedied for every
purpose of this Agreement. No such waiver shall extend to any subsequent or
other default or impair any right consequent thereon except to the extent
expressly so waived.

         Section 6.17. Notification to Holders. Upon termination of the Master
Servicer or appointment of a successor to the Master Servicer, in each case as
provided herein, the Trustee shall promptly mail notice thereof by first class
mail to the Certificateholders at their respective addresses appearing on the
Certificate Register. The Trustee shall also, within 45 days after the
occurrence of any Event of Default known to the Trustee, give written notice
thereof to Certificateholders, unless such Event of Default shall have been
cured or waived prior to the issuance of such notice and within such 45-day
period.

         Section 6.18. Directions by Certificateholders and Duties of Trustee
During Event of Default. Subject to the provisions of Section 8.01 hereof,
during the continuance of any Event of Default, Holders of Certificates
evidencing not less than 25% of the Class Principal Amount (or Class Notional
Amount) of each Class of Certificates may direct 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; provided, however, that the Trustee shall be under no obligation to
pursue any such remedy, or to exercise any of the trusts or powers vested in
it by this Agreement (including, without limitation, (i) the conducting or
defending of any administrative action or litigation hereunder or in relation
hereto and (ii) the terminating of the Master Servicer or any successor master
servicer from its rights and duties as master servicer hereunder) at the
request, order or direction of any of the Certificateholders, unless such
Certificateholders shall have offered to the Trustee reasonable security or
indemnity against the cost, expenses and liabilities which may be incurred
therein or thereby; and, provided further, that, subject to the provisions of
Section 8.01, the Trustee shall have the right to decline to follow any such
direction if the Trustee, in accordance with an Opinion of Counsel, determines
that the action or proceeding so directed may not lawfully be taken or if the
Trustee in good faith determines that the action or proceeding so directed
would involve it in personal liability or be unjustly prejudicial to the
non-assenting Certificateholders.

         Section 6.19. Action Upon Certain Failures of the Master Servicer and
Upon Event of Default. In the event that a Responsible Officer of the Trustee
shall have actual knowledge of any action or inaction of the Master Servicer
that would become an Event of Default upon the Master Servicer's failure to
remedy the same after notice, the Trustee shall give notice thereof to the
Master Servicer. For all purposes of this Agreement, in the absence of actual
knowledge by a Responsible Officer of the Trustee, the Trustee shall not be
deemed to have knowledge of any failure of the Master Servicer or any other
Event of Default unless notified in writing by the Depositor, the Master
Servicer or a Certificateholder.

         Section 6.20. Preparation of Tax Returns and Other Reports. (a) The
Trustee shall prepare or cause to be prepared on behalf of the Trust Fund,
based upon information calculated in accordance with this Agreement pursuant
to instructions given by the Depositor, and the Trustee shall file, federal
tax returns and appropriate state income tax returns and such other returns as
may be required by applicable law relating to the Trust Fund, and the Trustee
shall forward copies to the Depositor of all such returns and Form 1099
information and such other information within the control of the Trustee as
the Depositor may reasonably request in writing, and shall forward to each
Certificateholder such forms and furnish such information within the control
of the Trustee as are required by the Code and the REMIC Provisions to be
furnished to them, and will prepare and file annual reports required by
applicable state authorities, will file copies of this Agreement with the
appropriate state authorities as may be required by applicable law, and will
prepare and disseminate to Certificateholders Form 1099 (or otherwise furnish
information within the control of the Trustee) to the extent required by
applicable law. The Master Servicer will indemnify the Trustee for any
liability of or assessment against the Trustee resulting from any error in any
of such tax or information returns directly resulting from errors in the
information provided by such Master Servicer (other than information that is
derived solely from information provided by any Servicer).

         (b) The Trustee shall prepare and file with the Internal Revenue
Service ("IRS"), on behalf of the Trust Fund, an application on IRS Form SS-4.
The Trustee, upon receipt from the IRS of the Notice of Taxpayer
Identification Number Assigned, shall promptly forward a copy of such notice
to the Master Servicer and the Depositor.

         (c) The Depositor shall prepare or cause to be prepared the initial
current report on Form 8-K and thereafter the Trustee will prepare or cause to
be prepared Form 10-Ks and Form 10-Qs (if necessary), or monthly current
reports on Form 8-K, on behalf of the Trust Fund, as may be required by
applicable law, for filing with the Securities and Exchange Commission (the
"SEC"), and the Trustee will sign each such report on behalf of the Trust. The
Trustee will forward a copy of each such report to the Depositor promptly
after such report has been filed with the SEC. The Trustee agrees to use its
best commercial efforts to seek to terminate such filing obligation after the
period during which such filings are required under the Securities Exchange
Act of 1934. Promptly after filing a Form 15 or other applicable form with the
SEC in connection with such termination, the Trustee shall deliver to the
Depositor a copy of such form together with copies of confirmations of receipt
by the SEC of each report filed therewith on behalf of the Trust Fund.

                                 Article VII

                           PURCHASE AND TERMINATION
                               OF THE TRUST FUND

         Section 7.01. Termination of Trust Fund Upon Repurchase or
Liquidation of All Mortgage Loans. (a) The respective obligations and
responsibilities of the Trustee and the Master Servicer created hereby (other
than the obligation of the Trustee to make payments to Certificateholders as
set forth in Section 7.02, the obligation of the Master Servicer to make a
final remittance to the Trustee for deposit into the Certificate Account
pursuant to Section 4.01 and the obligations of the Master Servicer to the
Trustee pursuant to Sections 9.10 and 9.14), shall terminate on the earlier of
(i) the final payment or other liquidation of the last Mortgage Loan remaining
in the Trust Fund and the disposition of all REO Property and (ii) the sale of
all remaining property held by the Trust Fund in accordance with Section
7.01(b); provided, however, that in no event shall the Trust Fund created
hereby continue beyond 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. Any
termination of the Trust Fund shall be carried out in such a manner so that
the termination of each REMIC included therein shall qualify as a "qualified
liquidation" under the REMIC Provisions.

         (b) On any Distribution Date occurring after the date on which the
aggregate Scheduled Principal Balance of the Mortgage Loans is less than 10%
of the Cut-off Date Aggregate Principal Balance, the Master Servicer may, upon
written direction to the Trustee, cause (i) the Trustee to sell (or arrange
for the sale of) the assets of the Trust Fund and (ii) the Trust Fund to adopt
a plan of complete liquidation pursuant to Section 7.03 hereof to sell all of
its property. The property of the Trust Fund shall be sold at a price (the
"Termination Price") equal to: (i) 100% of the unpaid principal balance of
each Mortgage Loan on the day of such purchase plus interest accrued thereon
at the applicable Mortgage Rate with respect to any Mortgage Loan to the Due
Date in the Due Period immediately preceding the related Distribution Date to
the date of such repurchase, (ii) the fair market value of any REO Property
and any other property held by the Trust Fund, such fair market value to be
determined by an appraiser or appraisers appointed by the Master Servicer with
the consent of the Trustee and (iii) any unreimbursed Servicing Advances with
respect to each Mortgage Loan.

         Section 7.02. Procedure Upon Termination of Trust Fund. (a) Notice of
any termination pursuant to the provisions of Section 7.01, specifying the
Distribution Date upon which the final distribution shall be made, shall be
given promptly by the Trustee by first class mail to Certificateholders mailed
(x) no later than five Business Days after the Trustee has received notice
from the Master Servicer of its intent to exercise its right to cause the
termination of the Trust Fund pursuant to Section 7.01(b) or (y) upon the
final payment or other liquidation of the last Mortgage Loan or REO Property
in the Trust Fund. Such notice shall specify (A) the Distribution Date upon
which final distribution on the Certificates of all amounts required to be
distributed to Certificateholders pursuant to Section 5.02 will be made upon
presentation and surrender of the Certificates at the Corporate Trust Office,
and (B) that the Record Date otherwise applicable to such Distribution Date is
not applicable, distribution being made only upon presentation and surrender
of the Certificates at the office or agency of the Trustee therein specified.
The Trustee shall give such notice to the Depositor and the Certificate
Registrar at the time such notice is given to Holders of the Certificates.
Upon any such termination, the duties of the Certificate Registrar with
respect to the Certificates shall terminate and the Trustee shall terminate,
or request the Master Servicer to terminate, the Collection Account it
maintains, the Certificate Account and any other account or fund maintained
with respect to the Certificates, subject to the Trustee's obligation
hereunder to hold all amounts payable to Certificateholders in trust without
interest pending such payment.

         (b) In the event that all of the Holders do not surrender their
Certificates for cancellation within three months after the time specified in
the above-mentioned written notice, the Trustee 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 one year after the second notice any Certificates shall not have been
surrendered for cancellation, the Trustee may take appropriate steps to
contact the remaining Certificateholders concerning surrender of such
Certificates, and the cost thereof shall be paid out of the amounts
distributable to such Holders. If within two years after the second notice any
Certificates shall not have been surrendered for cancellation, the Trustee
shall, subject to applicable state law relating to escheatment, hold all
amounts distributable to such Holders for the benefit of such Holders. No
interest shall accrue on any amount held by the Trustee and not distributed to
a Certificateholder due to such Certificateholder's failure to surrender its
Certificate(s) for payment of the final distribution thereon in accordance
with this Section.

         (c) Any reasonable expenses incurred by the Trustee in connection
with any termination or liquidation of the Trust Fund shall be paid from
proceeds received from the liquidation of the Trust Fund.

         Section 7.03. Additional Requirements under the REMIC Provisions. .
(a) Any termination of the Trust Fund shall be effected in accordance with the
following additional requirements, unless the Trustee seeks (at the request of
the Master Servicer), and subsequently receives, an Opinion of Counsel (at the
expense of the Master Servicer), addressed to the Trustee to the effect that
the failure of the Trust Fund to comply with the requirements of this Section
7.03 will not (i) result in the imposition of taxes on any REMIC under the
REMIC Provisions or (ii) cause any REMIC established hereunder to fail to
qualify as a REMIC at any time that any Certificates are outstanding:

               (i) The Trustee shall sell all of the assets of the Trust Fund
          for cash and, within 90 days of such sale, shall distribute the
          proceeds of such sale to the Certificateholders in complete
          liquidation of the Trust Fund, the Lower Tier REMIC and the Upper
          Tier REMIC; and

               (ii) The Trustee shall attach a statement to the final Federal
          income tax return for each of the Lower Tier REMIC and the Upper
          Tier REMIC stating that pursuant to Treasury Regulation ss.
          1.860F-1, the first day of the 90-day liquidation period for each
          such REMIC was the date on which the Trustee sold the assets of the
          Trust Fund.

         (b) By its acceptance of a Residual Certificate, each Holder thereof
hereby (i) authorizes the Trustee to take the action described in paragraph
(a) above and (ii) agrees to take such other action as may be necessary to
facilitate liquidation of each REMIC created under this Agreement, which
authorization shall be binding upon all successor Residual Certificateholders.

                                 Article VIII

                         RIGHTS OF CERTIFICATEHOLDERS

         Section 8.01. Limitation on Rights of Holders. (a) The death or
incapacity of any Certificateholder shall not operate to terminate this
Agreement or this Trust Fund, nor entitle such Certificateholder's legal
representatives or heirs to claim an accounting or take any action or
proceeding in any court for a partition or winding up of this Trust Fund, nor
otherwise affect the rights, obligations and liabilities of the parties hereto
or any of them. Except as otherwise expressly provided herein, no
Certificateholder, solely by virtue of its status as a Certificateholder,
shall have any right to vote or in any manner otherwise control the Master
Servicer or 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 person by
reason of any action taken by the parties to this Agreement pursuant to any
provision hereof.

         (b) No Certificateholder, solely by virtue of its status as
Certificateholder, shall have any right by virtue or by availing of any
provision of this Agreement to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Agreement, unless such
Holder previously shall have given to the Trustee a written notice of an Event
of Default and of the continuance thereof, as hereinbefore provided, and
unless also the Holders of Certificates evidencing not less than 25% of the
Class Principal Amount (or Class Notional Amount) of Certificates of each
Class shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as Trustee hereunder and shall have
offered to the Trustee such reasonable indemnity as it may require against the
cost, expenses and liabilities to be incurred therein or thereby, and the
Trustee, for sixty 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 and no direction inconsistent with such written request has been
given such Trustee during such sixty-day period by such Certificateholders; 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 of any provision of this Agreement to
affect, disturb or prejudice the rights of the Holders of any other of such
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 benefit of all Certificateholders. For
the protection and enforcement of the provisions of this Section, each and
every Certificateholder and the Trustee shall be entitled to such relief as
can be given either at law or in equity.

         Section 8.02. Access to List of Holders. (a) If the Trustee is not
acting as Certificate Registrar, the Certificate Registrar will furnish or
cause to be furnished to the Trustee, within fifteen days after receipt by the
Certificate Registrar of a request by the Trustee in writing, a list, in such
form as the Trustee may reasonably require, of the names and addresses of the
Certificateholders of each Class as of the most recent Record Date.

         (b) If three or more Holders or Certificate Owners (hereinafter
referred to as "Applicants") apply in writing to the Trustee, and such
application states that the Applicants desire to communicate with other
Holders with respect to their rights under this Agreement or under the
Certificates and is accompanied by a copy of the communication which such
Applicants propose to transmit, then the Trustee shall, within five Business
Days after the receipt of such application, afford such Applicants reasonable
access during the normal business hours of the Trustee to the most recent list
of Certificateholders held by the Trustee or shall, as an alternative, send,
at the Applicants' expense, the written communication proffered by the
Applicants to all Certificateholders at their addresses as they appear in the
Certificate Register.

         (c) Every Holder or Certificate Owner, if the Holder is a Clearing
Agency, by receiving and holding a Certificate, agrees with the Depositor, the
Master Servicer, the Certificate Registrar and the Trustee that neither the
Depositor, the Master Servicer, the Certificate Registrar nor the Trustee
shall be held accountable by reason of the disclosure of any such information
as to the names and addresses of the Certificateholders hereunder, regardless
of the source from which such information was derived.

         Section 8.03. Acts of Holders of Certificates. (a) Any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by this Agreement to be given or taken by Holders or Certificate
Owner, if the Holder is a Clearing Agency, may be embodied in and evidenced by
one or more instruments of substantially similar tenor signed by such Holders
in person or by agent duly appointed in writing; and, except as herein
otherwise expressly provided, such action shall become effective when such
instrument or instruments are delivered to the Trustee and, where expressly
required herein, to the Master Servicer. Such instrument or instruments (as
the action embodies therein and evidenced thereby) are herein sometimes
referred to as an "Act" of the Holders signing such instrument or instruments.
Proof of execution of any such instrument or of a writing appointing any such
agents shall be sufficient for any purpose of this Agreement and conclusive in
favor of the Trustee and Master Servicer, if made in the manner provided in
this Section. Each of the Trustee and Master Servicer shall promptly notify
the other of receipt of any such instrument by it, and shall promptly forward
a copy of such instrument to the other.

         (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of any notary public or other officer
authorized by law to take acknowledgments or deeds, certifying that the
individual signing such instrument or writing acknowledged to him the
execution thereof. Whenever such execution is by an officer of a corporation
or a member of a partnership on behalf of such corporation or partnership,
such certificate or affidavit shall also constitute sufficient proof of his
authority. The fact and date of the execution of any such instrument or
writing, or the authority of the individual executing the same, may also be
proved in any other manner which the Trustee deems sufficient.

         (c) The ownership of Certificates (whether or not such Certificates
shall be overdue and notwithstanding any notation of ownership or other
writing thereon made by anyone other than the Trustee) shall be proved by the
Certificate Register, and neither the Trustee, the Master Servicer, nor the
Depositor shall be affected by any notice to the contrary.

         (d) Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Holder of any Certificate shall bind every
future Holder of the same Certificate and the Holder of every Certificate
issued upon the registration of transfer thereof or in exchange therefor or in
lieu thereof, in respect of anything done, omitted or suffered to be done by
the Trustee or the Master Servicer in reliance thereon, whether or not
notation of such action is made upon such Certificate.

                                  Article IX

                ADMINISTRATION AND SERVICING OF MORTGAGE LOANS
                            BY THE MASTER SERVICER

         Section 9.01. Duties of the Master Servicer. The Certificateholders,
by their purchase and acceptance of the Certificates, appoint Aurora Loan
Services Inc., as Master Servicer. For and on behalf of the Depositor, the
Trustee and the Certificateholders, the Master Servicer shall master service
the Mortgage Loans in accordance with the provisions of this Agreement and the
provisions of the applicable Servicing Agreement.

         Section 9.02. Master Servicer Fidelity Bond and Master Servicer
Errors and Omissions Insurance Policy. (a) The Master Servicer, at its
expense, shall maintain in effect a Fidelity Bond and an Errors and Omissions
Insurance Policy, affording coverage with respect to all directors, officers,
employees and other Persons acting on such Master Servicer's behalf, and
covering errors and omissions in the performance of the Master Servicer's
obligations hereunder. The Errors and Omissions Insurance Policy and the
Fidelity Bond shall be in such form and amount that would meet the
requirements of FNMA or FHLMC if it were the purchaser of the Mortgage Loans.
The Master Servicer shall (i) require each Servicer to maintain an Errors and
Omissions Insurance Policy and a Fidelity Bond in accordance with the
provisions of the applicable Servicing Agreement, (ii) cause each Servicer to
provide to the Master Servicer certificates evidencing that such policy and
bond is in effect and to furnish to the Master Servicer any notice of
cancellation, non-renewal or modification of the policy or bond received by
it, as and to the extent provided in the applicable Servicing Agreement, and
(iii) furnish copies of the certificates and notices referred to in clause
(ii) to the Trustee upon its request. The Fidelity Bond and Errors and
Omissions Insurance Policy may be obtained and maintained in blanket form.

         (b) The Master Servicer shall promptly report to the Trustee any
material changes that may occur in the Master Servicer Fidelity Bond or the
Master Servicer Errors and Omissions Insurance Policy and shall furnish to the
Trustee, on request, certificates evidencing that such bond and insurance
policy are in full force and effect. The Master Servicer shall promptly report
to the Trustee all cases of embezzlement or fraud, if such events involve
funds relating to the Mortgage Loans. The total losses, regardless of whether
claims are filed with the applicable insurer or surety, shall be disclosed in
such reports together with the amount of such losses covered by insurance. If
a bond or insurance claim report is filed with any of such bonding companies
or insurers, the Master Servicer shall promptly furnish a copy of such report
to the Trustee. Any amounts relating to the Mortgage Loans collected by the
Master Servicer under any such bond or policy shall be promptly remitted by
the Master Servicer to the Trustee for deposit into the Certificate Account.
Any amounts relating to the Mortgage Loans collected by any Servicer under any
such bond or policy shall be remitted to the Master Servicer to the extent
provided in the applicable Servicing Agreement.

         Section 9.03. Master Servicer's Financial Statements and Related
Information. For each year this Agreement is in effect, the Master Servicer
shall submit to the Trustee, each Rating Agency and the Depositor a copy of
its annual unaudited financial statements on or prior to August 31 of each
year. Such financial statements shall include a balance sheet, income
statement, statement of retained earnings, statement of additional paid-in
capital, statement of changes in financial position and all related notes and
schedules and shall be in comparative form, certified by a nationally
recognized firm of Independent Accountants to the effect that such statements
were examined and prepared in accordance with generally accepted accounting
principles applied on a basis consistent with that of the preceding year.

         Section 9.04. Power to Act; Procedures. (a) 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 Article X hereof, and
each Servicer shall have full power and authority (to the extent provided in
the applicable Servicing Agreement) to do any and all things that it may deem
necessary or desirable in connection with the 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 and the applicable
Servicing Agreement, as applicable; provided that the Master Servicer shall
not take, or knowingly permit any Servicer to take, any action that is
inconsistent with or prejudices the interests of the Trust Fund or the
Certificateholders in any Mortgage Loan or the rights and interests of the
Depositor, the Trustee and the Certificateholders under this Agreement. The
Master Servicer further is authorized and empowered by the Trustee, on behalf
of the Certificateholders and the Trustee, in its own name or in the name of
any Servicer, when the Master Servicer or a Servicer, as the case may be,
believes it is appropriate in its best judgment to register any Mortgage Loan
with MERS, 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
successors and assigns. The Master Servicer shall represent and protect the
interests of the Trust Fund in the same manner as it protects its own
interests in mortgage loans in its own portfolio in any claim, proceeding or
litigation regarding a Mortgage Loan and shall not make or knowingly permit
any Servicer to make any modification, waiver or amendment of any term of any
Mortgage Loan that would cause the Trust Fund to fail to qualify as a REMIC or
result in the imposition of any tax under Section 860F(a) or Section 860G(d)
of the Code. Without limiting the generality of the foregoing, the Master
Servicer in its own name or in the name of a Servicer, and each Servicer, to
the extent such authority is delegated to such Servicer by the Master Servicer
under the applicable Servicing Agreement, is hereby authorized and empowered
by the Trustee when the Master Servicer or a Servicer, as the case may be,
believes it appropriate in its best judgment and in accordance with Accepted
Servicing Practices and the applicable Servicing Agreement, to execute and
deliver, on behalf of itself and the Certificateholders, the Trustee or any of
them, any and all instruments of satisfaction or cancellation, or of partial
or full release or discharge and all other comparable instruments, with
respect to the Mortgage Loans and with respect to the Mortgaged Properties.
The Trustee shall furnish the Master Servicer, upon request, with any powers
of attorney empowering the Master Servicer or any Servicer 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 the
applicable Servicing Agreement and this Agreement, and the Trustee shall
execute and deliver such other documents, as the Master Servicer may request,
necessary or appropriate 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 Servicing Practices (and the Trustee shall have no
liability for misuse of any such powers of attorney by the Master Servicer or
the applicable Servicer). 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, then upon request of the
Trustee, the Master Servicer shall join with the Trustee in the appointment of
a co-trustee pursuant to Section 6.09 hereof. 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.

         (b) In master servicing and administering the Mortgage Loans, the
Master Servicer shall employ procedures, and shall cause each Servicer to
employ procedures (including, but not limited to, collection procedures),
consistent with the applicable Servicing Agreement. Consistent with the
foregoing, the Master Servicer may, and may permit any Servicer to, in its
discretion (i) waive any late payment charge or any prepayment charge or
penalty interest in connection with the prepayment of a Mortgage Loan and (ii)
extend the due dates for payments due on a Mortgage Note for a period not
greater than 120 days; provided, however, that the maturity of any Mortgage
Loan shall not be extended past the date on which the final payment is due on
the latest maturing Mortgage Loan as of the Cut-off Date. In the event of any
extension described in clause (ii) above, the Master Servicer shall make or
cause to be made Advances on the related Mortgage Loan in accordance with the
provisions of Section 5.04 on the basis of the amortization schedule of such
Mortgage Loan without modification thereof by reason of such extension.
Notwithstanding anything to the contrary in this Agreement, the Master
Servicer shall not, unless default by the related Mortgagor is, in the
reasonable judgment of the Master Servicer or the related Servicer, imminent,
make or knowingly permit such Servicer to make any modification, waiver or
amendment of any material term of any Mortgage Loan (including but not limited
to the interest rate, the principal balance, the amortization schedule, or any
other term affecting the amount or timing of payments on the Mortgage Loan or
the collateral therefor) unless the Master Servicer or the related Servicer
shall have provided or caused to be provided to the Trustee an Opinion of
Counsel (at the expense of the party seeking the modification) in writing to
the effect that such modification, waiver or amendment would not be treated as
giving rise to a new debt instrument for federal income tax purposes and would
not adversely affect the status of the REMIC.

         Section 9.05. Servicing Agreements Between the Master Servicer and
Servicers; Enforcement of Servicers' Obligations. (a) Each Servicing Agreement
requires the applicable Servicer to service the Mortgage Loans in accordance
with the provisions thereof. References in this Agreement to actions taken or
to be taken by the Master Servicer include such actions taken or to be taken
by a Servicer pursuant to a Servicing Agreement. Any fees, costs and expenses
and other amounts payable to such Servicers shall be deducted from amounts
remitted to the Master Servicer by the applicable Servicer and shall not be an
obligation of the Trust, the Trustee or the Master Servicer.

         (b) The Master Servicer, for the benefit of the Trustee and the
Certificateholders, shall enforce the obligations of each Servicer under the
related Servicing Agreement, and shall use its reasonable best efforts to
enforce the obligations of each Servicer under the related Servicing Agreement
and shall, upon its obtaining actual knowledge of the failure of a Servicer to
perform its obligations in accordance with the related Servicing Agreement, to
the extent that the non-performance of any such obligations would have a
material adverse effect on a Mortgage Loan, the Trust Fund or
Certificateholders, terminate the rights and obligations of such Servicer
thereunder to the extent and in the manner permitted by the related Servicing
Agreement and either act as servicer of the related Mortgage Loans or enter
into a Servicing Agreement with a successor Servicer. Such enforcement,
including, without limitation, the legal prosecution of claims, termination of
Servicing Agreements 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
enforcement at its own expense, and shall be reimbursed therefor initially
only (i) from a general recovery resulting from such enforcement only to the
extent, if any, that such recovery exceeds all amounts due in respect of the
related Mortgage Loans or (ii) from a specific recovery of costs, expenses or
attorneys' fees against the party against whom such enforcement is directed,
and then, to the extent that such amounts are insufficient to reimburse the
Master Servicer for the costs of such enforcement, (iii) from the Collection
Account.

         Section 9.06. Collection of Taxes, Assessments and Similar Items. (a)
To the extent provided in the applicable Servicing Agreement, the Master
Servicer shall cause each Servicer to establish and maintain one or more
custodial accounts at a depository institution (which may be a depository
institution with which the Master Servicer or any Servicer establishes
accounts in the ordinary course of its servicing activities), the accounts of
which are insured to the maximum extent permitted by the FDIC (each, an
"Escrow Account") and shall deposit therein any collections of amounts
received with respect to amounts due for taxes, assessments, water rates,
Standard Hazard Insurance Policy premiums or any comparable items for the
account of the Mortgagors. Withdrawals from any Escrow Account may be made (to
the extent amounts have been escrowed for such purpose) only in accordance
with the applicable Servicing Agreement. Each Servicer shall be entitled to
all investment income not required to be paid to Mortgagors on any Escrow
Account maintained by such Servicer. The Master Servicer shall make (or cause
to be made) to the extent provided in the applicable Servicing Agreement
advances to the extent necessary in order to effect timely payment of taxes,
water rates, assessments, Standard Hazard Insurance Policy premiums or
comparable items in connection with the related Mortgage Loan (to the extent
that the Mortgagor is required, but fails, to pay such items), provided that
it has determined that the funds so advanced are recoverable from escrow
payments, reimbursement pursuant to Section 4.02(v) or otherwise.

         (b) Costs incurred by the Master Servicer or by Servicers in
effecting the timely payment of taxes and assessments on the properties
subject to the Mortgage Loans may be added to the amount owing under the
related Mortgage Note where the terms of the Mortgage Note so permit;
provided, however, that the addition of any such cost shall not be taken into
account for purposes of calculating the distributions to be made to
Certificateholders. Such costs, to the extent that they are unanticipated,
extraordinary costs, and not ordinary or routine costs shall be recoverable by
the Master Servicer pursuant to Section 4.02(v).

         Section 9.07. Termination of Servicing Agreements; Successor
Servicers. (a) The Master Servicer shall be entitled to terminate the rights
and obligations of any Servicer under the applicable Servicing Agreement in
accordance with the terms and conditions of such Servicing Agreement and
without any limitation by virtue of this Agreement; provided, however, that in
the event of termination of any Servicing Agreement by the Master Servicer or
the related Servicer, the Master Servicer shall either act as Servicer of the
related Mortgage Loans, or enter into a Servicing Agreement with a successor
Servicer.

         (b) If the Master Servicer acts as Servicer, it will not assume
liability for the representations and warranties of the Servicer, if any, that
it replaces. The Master Servicer shall use reasonable efforts to have the
successor Servicer assume liability for the representations and warranties
made by the terminated Servicer in respect of the related Mortgage Loans, and
in the event of any such assumption by the successor Servicer, the Trustee or
the Master Servicer, as applicable, may, in the exercise of its business
judgment, release the terminated Servicer from liability for such
representations and warranties.

         Section 9.08. Master Servicer Liable for Enforcement. Notwithstanding
any Servicing Agreement, the Master Servicer shall remain obligated and liable
to the Trustee and the Certificateholders in accordance with the provisions of
this Agreement, to the extent of its obligations hereunder, without diminution
of such obligation or liability by virtue of such Servicing Agreements or
arrangements. The Master Servicer shall use commercially reasonable efforts to
ensure that the Mortgage Loans are serviced in accordance with the provisions
of this Agreement and shall use commercially reasonable efforts to enforce the
provisions of each Servicing Agreement for the benefit of the
Certificateholders. The Master Servicer shall be entitled to enter into any
agreement with the Servicers for indemnification of the Master Servicer and
nothing contained in this Agreement shall be deemed to limit or modify such
indemnification. Except as expressly set forth herein, the Master Servicer
shall have no liability for the acts or omissions of any Servicer in the
performance by such Servicer of its obligations under the related Servicing
Agreement.

         Section 9.09. No Contractual Relationship Between Servicers and
Trustee or Depositor. Any Servicing Agreement that may be entered into and any
other transactions or services relating to the Mortgage Loans involving a
Servicer in its capacity as such and not as an originator shall be deemed to
be between such Servicer, the Seller and the Master Servicer, and the Trustee
and the Depositor shall not be deemed parties thereto and shall have no
claims, rights, obligations, duties or liabilities with respect to such
Servicer except as set forth in Section 9.10 hereof.

         Section 9.10. Assumption of Servicing Agreement by Trustee. (a) In
the event the Master Servicer shall for any reason no longer be the Master
Servicer (including by reason of any Event of Default under this Agreement),
the Trustee shall thereupon assume all of the rights and obligations of such
Master Servicer hereunder and under each Servicing Agreement entered into with
respect to the Mortgage Loans. The Trustee, its designee or any successor
master servicer appointed by the Trustee shall be deemed to have assumed all
of the Master Servicer's interest herein and therein to the same extent as if
such Servicing Agreement had been assigned to the assuming party, except that
the Master Servicer shall not thereby be relieved of any liability or
obligations of the Master Servicer under such Servicing Agreement accruing
prior to its replacement as Master Servicer, and shall be liable to the
Trustee, and hereby agrees to indemnify and hold harmless the Trustee from and
against all costs, damages, expenses and liabilities (including reasonable
attorneys' fees) incurred by the Trustee as a result of such liability or
obligations of the Master Servicer and in connection with the Trustee's
assumption (but not its performance, except to the extent that costs or
liability of the Trustee are created or increased as a result of negligent or
wrongful acts or omissions of the Master Servicer prior to its replacement as
Master Servicer) of the Master Servicer's obligations, duties or
responsibilities thereunder; provided that the Master Servicer shall not
indemnify or hold harmless the Trustee against negligent or willful misconduct
of the Trustee.

         (b) The Master Servicer that has been terminated shall, upon request
of the Trustee but at the expense of such Master Servicer, deliver to the
assuming party all documents and records relating to each Servicing Agreement
and the related Mortgage Loans and an accounting of amounts collected and held
by it and otherwise use its best efforts to effect the orderly and efficient
transfer of each Servicing Agreement to the assuming party.

         Section 9.11. "Due-on-Sale" Clauses; Assumption Agreements. (a) To
the extent provided in the applicable Servicing Agreement, to the extent
Mortgage Loans contain enforceable due-on-sale clauses, and to the extent that
the Master Servicer has knowledge of the conveyance of a Mortgaged Property,
the Master Servicer shall use its reasonable best efforts to cause the
Servicers to enforce such clauses in accordance with the applicable Servicing
Agreement. If applicable law prohibits the enforcement of a due-on-sale clause
or such clause is otherwise not enforced in accordance with the applicable
Servicing Agreement, and, as a consequence, a Mortgage Loan is assumed, the
original Mortgagor may be released from liability in accordance with the
applicable Servicing Agreement.

         (b) The Master Servicer or the related Servicer, as the case may be,
shall be entitled to approve a request from a Mortgagor for the granting of an
easement thereon in favor of another Person or any alteration or demolition of
the related Mortgaged Property if it has determined, exercising its good faith
business judgment in the same manner as it would if it were the owner of the
related Mortgage Loan, that the security for, and the timely and full
collectability of, such Mortgage Loan would not be materially adversely
affected thereby. Any fee collected by the Master Servicer or the related
Servicer for processing such a request will be retained by the Master Servicer
or such Servicer as additional servicing compensation.

         Section 9.12. Release of Mortgage Files. (a) Upon (i) becoming aware
of the payment in full of any Mortgage Loan, (ii) the receipt by the Master
Servicer of a notification that payment in full has been or will be escrowed
in a manner customary for such purposes, or (iii) in the case of a Mortgage
Loan as to which the related Mortgaged Property is located in California,
receipt by the Master Servicer of notification from the Servicer that the
Servicer reasonably expects that payment in full will be received promptly,
the Master Servicer will, or will cause the applicable Servicer to, promptly
notify the Trustee (or the applicable Custodian) by a certification (which
certification shall include a statement to the effect that all amounts
received or to be received in connection with such payment that are required
to be deposited in the Collection Account maintained by the Master Servicer
pursuant to Section 4.01 have been or will be so deposited) of a Servicing
Officer and shall request the Trustee or the applicable Custodian, to deliver
to the applicable Servicer the related Mortgage File. In lieu of sending a
hard copy certification of a Servicing Officer, the Master Servicer may, or
may cause the Servicer to, deliver the request for release in a mutually
agreeable electronic format. To the extent that such a request, on its face,
originates from a Servicing Officer, no signature shall be required. Upon
receipt of such certification and request, the Trustee or the applicable
Custodian, shall promptly release the related Mortgage File to the applicable
Servicer and neither the Trustee nor the Custodian shall have any further
responsibility with regard to such Mortgage File. The Master Servicer is
authorized, and each Servicer, to the extent such authority is delegated to
such Servicer by the Master Servicer under the applicable Servicing Agreement,
is authorized, to give, as agent for the Trustee, as the mortgagee under the
Mortgage that secured the Mortgage Loan, an instrument of satisfaction (or
assignment of mortgage without recourse) regarding the Mortgaged Property
subject to the Mortgage, which instrument of satisfaction or assignment, as
the case may be, shall be delivered to the Person or Persons entitled thereto
against receipt therefor of such payment, it being understood and agreed that
no expenses incurred in connection with such instrument of satisfaction or
assignment, as the case may be, shall be chargeable to the Collection Account.

         (b) From time to time and as appropriate for the servicing or
foreclosure of, or other legal proceedings relating to, any Mortgage Loan and
in accordance with Accepted Servicing Practices and the applicable Servicing
Agreement, the Trustee shall execute such pleadings, request for trustee's
sale or other documents as shall be prepared and furnished to the Trustee by
the Master Servicer, or by a Servicer (in form reasonably acceptable to the
Trustee) and as are necessary to the prosecution of any such proceedings. The
Trustee or the Custodian, shall, upon request of the Master Servicer, or of a
Servicer, and delivery to the Trustee or the applicable Custodian, of a trust
receipt signed by a Servicing Officer substantially in the form annexed hereto
as Exhibit C or in the form annexed to the applicable Custodial Agreement as
Exhibit C, release the related Mortgage File held in its possession or control
to the Master Servicer (or the applicable Servicer). Such trust receipt shall
obligate the Master Servicer or applicable Servicer to return the Mortgage
File to the Trustee or Custodian, as applicable, when the need therefor by the
Master Servicer or applicable Servicer no longer exists unless (i) the
Mortgage Loan shall be liquidated, in which case, upon receipt of a
certificate of a Servicing Officer similar to that herein above specified, the
trust receipt shall be released by the Trustee or the Custodian, as
applicable, to the Master Servicer (or the applicable Servicer) or (ii) the
Mortgage File has been delivered directly or through a Servicer to an
attorney, or to a public trustee or other public official as required by law,
for purposes of initiating or pursuing legal action or other proceedings for
the foreclosure of the Mortgaged Property either judicially or non-judicially,
and the Master Servicer has delivered directly or through a Servicer to the
Trustee a certificate of a Servicing Officer certifying as to the name and
address of the Person to which such Mortgage File or such document was
delivered and the purpose or purposes of such delivery.

         Section 9.13. Documents, Records and Funds in Possession of Master
Servicer To Be Held for Trustee. (a) The Master Servicer shall transmit, or
cause the applicable Servicer to transmit, to the Trustee such documents and
instruments coming into the possession of the Master Servicer or such Servicer
from time to time as are required by the terms hereof to be delivered to the
Trustee. Any funds received by the Master Servicer or by a Servicer in respect
of any Mortgage Loan or which otherwise are collected by the Master Servicer
or by a Servicer as Liquidation Proceeds or Insurance Proceeds in respect of
any Mortgage Loan shall be held for the benefit of the Trustee and the
Certificateholders subject to the Master Servicer's right to retain or
withdraw from the Collection Account the Master Servicing Fee and other
amounts provided in this Agreement, and to the right of each Servicer to
retain its Servicing Fee and other amounts as provided in the applicable
Servicing Agreement. The Master Servicer shall, and shall (to the extent
provided in the applicable Servicing Agreement) cause each Servicer to,
provide access to information and documentation regarding the Mortgage Loans
to the Trustee, its agents and accountants at any time upon reasonable request
and during normal business hours, and to Certificateholders that are savings
and loan associations, banks or insurance companies, the Office of Thrift
Supervision, the FDIC and the supervisory agents and examiners of such Office
and Corporation or examiners of any other federal or state banking or
insurance regulatory authority if so required by applicable regulations of the
Office of Thrift Supervision or other regulatory authority, such access to be
afforded without charge but only upon reasonable request in writing and during
normal business hours at the offices of the Master Servicer designated by it.
In fulfilling such a request the Master Servicer shall not be responsible for
determining the sufficiency of such information.

         (b) All Mortgage Files and funds collected or held by, or under the
control of, the Master Servicer, or any Servicer, in respect of any Mortgage
Loans, whether from the collection of principal and interest payments or from
Liquidation Proceeds or Insurance Proceeds, shall be held by the Master
Servicer, or by such Servicer, for and on behalf of the Trustee and the
Certificateholders and shall be and remain the sole and exclusive property of
the Trustee; provided, however, that the Master Servicer and each Servicer
shall be entitled to setoff against, and deduct from, any such funds any
amounts that are properly due and payable to the Master Servicer or such
Servicer under this Agreement or the applicable Servicing Agreement.

         (c) The Master Servicer hereby acknowledges that concurrently with
the execution of this Agreement, the Trustee shall own or, to the extent that
a court of competent jurisdiction shall deem the conveyance of the Mortgage
Loans from the Seller to the Depositor not to constitute a sale, the Trustee
shall have a security interest in the Mortgage Loans and in all Mortgage Files
representing such Mortgage Loans and in all funds now or hereafter held by, or
under the control of, a Servicer or the Master Servicer that are collected by
such Servicer or the Master Servicer in connection with the Mortgage Loans,
whether as scheduled installments of principal and interest or as full or
partial prepayments of principal or interest or as Liquidation Proceeds or
Insurance Proceeds or otherwise, and in all proceeds of the foregoing and
proceeds of proceeds (but excluding any fee or other amounts to which such
Servicer is entitled under the applicable Servicing Agreement, or the Master
Servicer or the Depositor is entitled to hereunder); and the Master Servicer
agrees that so long as the Mortgage Loans are assigned to and held by the
Trustee, all documents or instruments constituting part of the Mortgage Files,
and such funds relating to the Mortgage Loans which come into the possession
or custody of, or which are subject to the control of, the Master Servicer or
any Servicer shall be held by the Master Servicer or such Servicer for and on
behalf of the Trustee as the Trustee's agent and bailee for purposes of
perfecting the Trustee's security interest therein as provided by the
applicable Uniform Commercial Code or other laws.

         (d) The Master Servicer agrees that it shall not, and shall not
authorize any Servicer to, create, incur or subject any Mortgage Loans, or any
funds that are deposited in any custodial account, Escrow Account or the
Collection Account, or any funds that otherwise are or may become due or
payable to the Trustee, to any claim, lien, security interest, judgment, levy,
writ of attachment or other encumbrance, nor assert by legal action or
otherwise any claim or right of setoff against any Mortgage Loan or any funds
collected on, or in connection with, a Mortgage Loan.

         Section 9.14. Representations and Warranties of the Master Servicer.
(a) The Master Servicer hereby represents and warrants to the Depositor and
the Trustee, for the benefit of the Certificateholders, as of the Closing Date
that:

               (i) it is validly existing and in good standing under the
          jurisdiction of its formation, and as Master Servicer has full power
          and authority to transact any and all business contemplated by this
          Agreement and to execute, deliver and comply with its obligations
          under the terms of this Agreement, the execution, delivery and
          performance of which have been duly authorized by all necessary
          corporate action on the part of the Master Servicer;

              (ii) the execution and delivery of this Agreement by the Master
          Servicer and its performance and compliance with the terms of this
          Agreement will not (A) violate the Master Servicer's charter or
          bylaws, (B) violate any law or regulation or any administrative
          decree or order to which it is subject or (C) constitute a default
          (or an event which, with notice or lapse of time, or both, would
          constitute a default) under, or result in the breach of, any
          material contract, agreement or other instrument to which the Master
          Servicer is a party or by which it is bound or to which any of its
          assets are subject, which violation, default or breach would
          materially and adversely affect the Master Servicer's ability to
          perform its obligations under this Agreement;

               (iii) this Agreement constitutes, assuming due authorization,
          execution and delivery hereof by the other respective parties
          hereto, a legal, valid and binding obligation of the Master
          Servicer, enforceable against it in accordance with the terms
          hereof, except as such enforcement may be limited by bankruptcy,
          insolvency, reorganization, moratorium and other laws affecting the
          enforcement of creditors' rights in general, and by general equity
          principles (regardless of whether such enforcement is considered in
          a proceeding in equity or at law);

               (iv) the Master Servicer is not in default with respect to any
          order or decree of any court or any order or regulation of any
          federal, state, municipal or governmental agency to the extent that
          any such default would materially and adversely affect its
          performance hereunder;

               (v) the Master Servicer is not a party to or bound by any
          agreement or instrument or subject to any charter provision, bylaw
          or any other corporate restriction or any judgment, order, writ,
          injunction, decree, law or regulation that may materially and
          adversely affect its ability as Master Servicer to perform its
          obligations under this Agreement or that requires the consent of any
          third person to the execution of this Agreement or the performance
          by the Master Servicer of its obligations under this Agreement;

               (vi) no litigation is pending or, to the best of the Master
          Servicer's knowledge, threatened against the Master Servicer which
          would prohibit its entering into this Agreement or performing its
          obligations under this Agreement;

               (vii) the Master Servicer, or an affiliate thereof the primary
          business of which is the servicing of conventional residential
          mortgage loans, is an FNMA- and FHLMC- approved seller/servicer;

               (viii) no consent, approval, authorization or order of any
          court or governmental agency or body is required for the execution,
          delivery and performance by the Master Servicer of or compliance by
          the Master Servicer with this Agreement or the consummation of the
          transactions contemplated by this Agreement, except for such
          consents, approvals, authorizations and orders (if any) as have been
          obtained;

               (ix) the consummation of the transactions contemplated by this
          Agreement are in the ordinary course of business of the Master
          Servicer; and

               (x) the Master Servicer has obtained an Errors and Omissions
          Insurance Policy and a Fidelity Bond in accordance with Section
          9.02, each of which is in full force and effect, and each of which
          provides at least such coverage as is required hereunder.

         (b) It is understood and agreed that the representations and
warranties set forth in this Section 9.14 shall survive the execution and
delivery of this Agreement. The Master Servicer shall indemnify the Depositor
and the Trustee and hold them harmless against any loss, damages, penalties,
fines, forfeitures, legal fees and related costs, judgments, and other costs
and expenses resulting from any claim, demand, defense or assertion based on
or grounded upon, or resulting from, a breach of the Master Servicer's
representations and warranties contained in Section 9.14(a). Notwithstanding
anything in this Agreement to the contrary, the Master Servicer shall not be
liable for special, indirect or consequential losses or damages of any kind
whatsoever (including, but not limited to, lost profits). It is understood and
agreed that the enforcement of the obligation of the Master Servicer set forth
in this Section to indemnify the Depositor and the Trustee as provided in this
Section constitutes the sole remedy (other than as set forth in Section 6.14)
of the Depositor and the Trustee, respecting a breach of the foregoing
representations and warranties. Such indemnification shall survive any
termination of the Master Servicer as Master Servicer hereunder, and any
termination of this Agreement.

         Any cause of action against the Master Servicer relating to or
arising out of the breach of any representations and warranties made in this
Section shall accrue upon discovery of such breach by either the Depositor,
the Master Servicer or the Trustee or notice thereof by any one of such
parties to the other parties.

         (c) It is understood and agreed that the representations and
warranties of the Depositor set forth in Sections 2.03(a) through (f) shall
survive the execution and delivery of this Agreement. The Depositor shall
indemnify the Master Servicer and hold it harmless against any loss, damages,
penalties, fines, forfeitures, legal fees and related costs, judgments, and
other costs and expenses resulting from any claim, demand, defense or
assertion based on or grounded upon, or resulting from, a breach of the
Depositor's representations and warranties contained in Sections 2.03(a)
through (f) hereof. It is understood and agreed that the enforcement of the
obligation of the Depositor set forth in this Section to indemnify the Master
Servicer as provided in this Section constitutes the sole remedy of the Master
Servicer respecting a breach by the Depositor of the representations and
warranties in Sections 2.03(a) through (f) hereof.

         Any cause of action against the Depositor relating to or arising out
of the breach of the representations and warranties made in Sections 2.03(a)
through (f) hereof shall accrue upon discovery of such breach by either the
Depositor or the Master Servicer or notice thereof by any one of such parties
to the other parties.

         Section 9.15. Closing Certificate and Opinion. On or before the
Closing Date, the Master Servicer shall cause to be delivered to the Depositor
and Lehman Brothers Inc. an Opinion of Counsel, dated the Closing Date, in
form and substance reasonably satisfactory to the Depositor and Lehman
Brothers Inc., as to the due authorization, execution and delivery of this
Agreement by the Master Servicer and the enforceability thereof.

         Section 9.16. Standard Hazard and Flood Insurance Policies. For each
Mortgage Loan (other than a Cooperative Loan), the Master Servicer shall
maintain, or cause to be maintained by each Servicer, standard fire and
casualty insurance and, where applicable, flood insurance, all in accordance
with the provisions of this Agreement and the related Servicing Agreement, as
applicable. It is understood and agreed that such insurance shall be with
insurers meeting the eligibility requirements set forth in the applicable
Servicing Agreement and that no earthquake or other additional insurance is to
be required of any Mortgagor or to be maintained on property acquired in
respect of a defaulted loan, other than pursuant to such applicable laws and
regulations as shall at any time be in force and as shall require such
additional insurance.

         Pursuant to Section 4.01, any amounts collected by the Master
Servicer, or by any Servicer, under any insurance policies maintained pursuant
to this Section 9.16 (other than amounts to be applied to the restoration or
repair of the property subject to the related Mortgage or released to the
Mortgagor in accordance with the Master Servicer's or the Servicer's normal
servicing procedures and Accepted Servicing Practices) shall be deposited into
the Collection Account, subject to withdrawal pursuant to Section 4.02. Any
cost incurred by the Master Servicer or any Servicer in maintaining any such
insurance if the Mortgagor defaults in its obligation to do so shall be added
to the amount owing under the Mortgage Loan where the terms of the Mortgage
Loan so permit; provided, however, that the addition of any such cost shall
not be taken into account for purposes of calculating the distributions to be
made to Certificateholders and shall be recoverable by the Master Servicer or
such Servicer pursuant to Section 4.02(v).

         Section 9.17. Presentment of Claims and Collection of Proceeds. The
Master Servicer shall, or shall cause each Servicer (to the extent provided in
the applicable Servicing Agreement) to, prepare and present on behalf of the
Trustee and the Certificateholders all claims under the Insurance Policies
with respect to the Mortgage Loans, and take such actions (including the
negotiation, settlement, compromise or enforcement of the insured's claim) as
shall be necessary to realize recovery under such policies. Any proceeds
disbursed to the Master Servicer (or disbursed to a Servicer and remitted to
the Master Servicer) in respect of such policies or bonds shall be promptly
deposited in the Collection Account upon receipt, except that any amounts
realized that are to be applied to the repair or restoration of the related
Mortgaged Property or release to the Mortgagor in accordance with the Master
Servicer's or the Servicer's normal servicing procedures need not be so
deposited (or remitted).

         Section 9.18. Maintenance of the Primary Mortgage Insurance Policies.
(a) The Master Servicer shall not take, or knowingly permit any Servicer
(consistent with the applicable Servicing Agreement) to take, any action that
would result in non-coverage under any applicable Primary Mortgage Insurance
Policy of any loss which, but for the actions of such Master Servicer or
Servicer, would have been covered thereunder. To the extent that coverage is
available, the Master Servicer shall use its best reasonable efforts to keep
in force and effect, or to cause each Servicer to keep in force and effect (to
the extent that the Mortgage Loan requires the Mortgagor to maintain such
insurance), primary mortgage insurance applicable to each Mortgage Loan in
accordance with the provisions of this Agreement and the related Servicing
Agreement, as applicable. The Master Servicer shall not, and shall not permit
any Servicer to, cancel or refuse to renew any such Primary Mortgage Insurance
Policy that is in effect at the date of the initial issuance of the
Certificates and is required to be kept in force hereunder except as required
by a applicable law or in accordance with the provisions of this Agreement and
the related Servicing Agreement, as applicable.

         (b) The Master Servicer agrees to present, or to cause each Servicer
to present, on behalf of the Trustee and the Certificateholders, claims to the
insurer under any Primary Mortgage Insurance Policies and, in this regard, to
take such reasonable action as shall be necessary to permit recovery under any
Primary Mortgage Insurance Policies respecting defaulted Mortgage Loans.
Pursuant to Section 4.01, any amounts collected by the Master Servicer or any
Servicer under any Primary Mortgage Insurance Policies shall be deposited in
the Collection Account, subject to withdrawal pursuant to Section 4.02.

         Section 9.19. Trustee To Retain Possession of Certain Insurance
Policies and Documents. The Trustee (or its custodian, if any, as directed by
the Trustee), shall retain possession and custody of the originals of the
Primary Mortgage Insurance Policies or certificate of insurance if applicable
and any certificates of renewal as to the foregoing as may be issued from time
to time as contemplated by this Agreement. Until all amounts distributable in
respect of the Certificates have been distributed in full and the Master
Servicer otherwise has fulfilled its obligations under this Agreement, the
Trustee (or its custodian, if any, as directed by the Trustee) shall also
retain possession and custody of each Mortgage File in accordance with and
subject to the terms and conditions of this Agreement. The Master Servicer
shall promptly deliver or cause to be delivered to the Trustee (or its
custodian, if any, as directed by the Trustee), upon the execution or receipt
thereof the originals of the Primary Mortgage Insurance Policies and any
certificates of renewal thereof, and such other documents or instruments that
constitute portions of the Mortgage File that come into the possession of the
Master Servicer from time to time.

         Section 9.20. Realization Upon Defaulted Mortgage Loans. The Master
Servicer shall use its reasonable best efforts to, or to cause each Servicer
to, foreclose upon, repossess or otherwise comparably convert the ownership of
Mortgaged 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, all in accordance with the applicable
Servicing Agreement. Alternatively, the Master Servicer may take, or authorize
any Servicer to take, other actions in respect of a defaulted Mortgage Loan,
which may include (i) accepting a short sale (a payoff of the Mortgage Loan
for an amount less than the total amount contractually owed in order to
facilitate a sale of the Mortgaged Property by the Mortgagor) or permitting a
short refinancing (a payoff of the Mortgage Loan for an amount less than the
total amount contractually owed in order to facilitate refinancing
transactions by the Mortgagor not involving a sale of the Mortgaged Property),
(ii) arranging for a repayment plan or (iii) agreeing to a modification in
accordance with Section 9.04. In connection with such foreclosure or other
conversion or action, the Master Servicer shall, consistent with Section 9.18,
follow such practices and procedures as it shall reasonably determine to be in
the best interests of the Trust Fund and the Certificateholders and which
shall be consistent with its customary practices in performing its general
mortgage servicing activities; provided that the Master Servicer shall not be
liable in any respect hereunder if the Master Servicer is acting in connection
with any such foreclosure or other conversion or action in a manner that is
consistent with the provisions of this Agreement. Neither the Master Servicer,
nor any Servicer, shall be required to expend its own funds or incur other
reimbursable charges in connection with any foreclosure, or attempted
foreclosure which is not completed, or toward the correction of any default on
a related senior mortgage loan, or towards the restoration of any property
unless it shall determine (i) that such restoration and/or foreclosure will
increase the proceeds of liquidation of the Mortgage Loan to the
Certificateholders after reimbursement to itself for such expenses or charges
and (ii) that such expenses and charges will be recoverable to it through
Liquidation Proceeds or Insurance Proceeds (as provided in Section 4.02).

         Section 9.21. Compensation to the Master Servicer. The Master
Servicer shall (i) be entitled, at its election, either (a) to pay itself the
Master Servicing Fee, as reduced pursuant to Section 5.05, in respect of the
Mortgage Loans out of any Mortgagor payment on account of interest prior to
the deposit of such payment in the Collection Account it maintains or (b) to
withdraw from the Collection Account, subject to Section 5.05, the Master
Servicing Fee to the extent permitted by Section 4.02(iv). The Master Servicer
shall also be entitled, at its election, either (a) to pay itself the Master
Servicing Fee in respect of each delinquent Mortgage Loan master serviced by
it out of Liquidation Proceeds in respect of such Mortgage Loan or other
recoveries with respect thereto to the extent permitted in Section 4.02 or (b)
to withdraw from the Collection Account it maintains the Master Servicing Fee
in respect of each Liquidated Mortgage Loan to the extent of such Liquidation
Proceeds or other recoveries, to the extent permitted by Section 4.02.
Servicing compensation in the form of assumption fees, if any, late payment
charges, as collected, if any, or otherwise (including any Prepayment Penalty
Amount) shall be retained by the Master Servicer (or the applicable Servicer)
and shall not be deposited in the Collection Account. If the Master Servicer
does not retain or withdraw the Master Servicing Fee from the Collection
Account as provided herein, the Master Servicer shall be entitled to direct
the Trustee to pay the Master Servicing Fee to such Master Servicer by
withdrawal from the Certificate Account to the extent that payments have been
received with respect to the applicable Mortgage Loan. The Master Servicer
shall be required to pay all expenses incurred by it in connection with its
activities hereunder and shall not be entitled to reimbursement therefor
except as provided in this Agreement. Pursuant to Section 4.01(e), all income
and gain realized from any investment of funds in the Collection Account shall
be for the benefit of the Master Servicer as additional compensation. The
provisions of this Section 9.21 are subject to the provisions of Section
6.14(b).

         Section 9.22. REO Property. (a) In the event the Trust Fund acquires
ownership of any REO Property in respect of any Mortgage Loan, the deed or
certificate of sale shall be issued to the Trustee, or to its nominee, on
behalf of the Certificateholders. The Master Servicer shall use its reasonable
best efforts to sell, or, to the extent provided in the applicable Servicing
Agreement, cause the applicable Servicer to sell, any REO Property as
expeditiously as possible and in accordance with the provisions of this
Agreement and the related Servicing Agreement, as applicable, but in all
events within the time period, and subject to the conditions set forth in
Article X hereof. Pursuant to its efforts to sell such REO Property, the
Master Servicer shall protect and conserve, or cause the applicable Servicer
to protect and conserve, such REO Property in the manner and to such extent
required by the applicable Servicing Agreement, subject to Article X hereof.

         (b) The Master Servicer shall deposit or cause to be deposited all
funds collected and received by it, or recovered from any Servicer, in
connection with the operation of any REO Property in the Collection Account.

         (c) The Master Servicer and the applicable Servicer, upon the final
disposition of any REO Property, shall be entitled to reimbursement for any
related unreimbursed Advances as well as any unpaid Master Servicing Fees or
Servicing Fees from Liquidation Proceeds received in connection with the final
disposition of such REO Property; provided, that any such unreimbursed
Advances as well as any unpaid Master Servicing Fees or Servicing Fees may be
reimbursed or paid, as the case may be, prior to final disposition, out of any
net rental income or other net amounts derived from such REO Property.

         (d) The Liquidation Proceeds from the final disposition of the REO
Property, net of any payment to the Master Servicer and the applicable
Servicer as provided above, shall be deposited in the Collection Account on or
prior to the Determination Date in the month following receipt thereof (and
the Master Servicer shall provide prompt written notice to the Trustee upon
such deposit) and be remitted by wire transfer in immediately available funds
to the Trustee for deposit into the Certificate Account on the next succeeding
Deposit Date.

         Section 9.23. [Omitted]

         Section 9.24. Reports to the Trustee. (a) Not later than 30
days after each Distribution Date, the Master Servicer shall forward to the
Trustee a statement, deemed to have been certified by a Servicing Officer,
setting forth the status of the Collection Account maintained by the Master
Servicer as of the close of business on the related Distribution Date,
indicating that all distributions required by this Agreement to be made by the
Master Servicer have been made (or if any required distribution has not been
made by the Master Servicer, specifying the nature and status thereof) and
showing, for the period covered by such statement, the aggregate of deposits
into and withdrawals from the Collection Account maintained by the Master
Servicer. Copies of such statement shall be provided by the Master Servicer to
the Depositor, Attention: Contract Finance, and, upon request, any
Certificateholders (or by the Trustee at the Master Servicer's expense if the
Master Servicer shall fail to provide such copies (unless (i) the Master
Servicer shall have failed to provide the Trustee with such statement or (ii)
the Trustee shall be unaware of the Master Servicer's failure to provide such
statement)).

         (b) Not later than two Business Days following each Distribution
Date, the Master Servicer shall deliver to the Person designated by the
Depositor, in a format consistent with other electronic loan level reporting
supplied by the Master Servicer in connection with similar transactions, "loan
level" information with respect to the Mortgage Loans as of the related
Determination Date, to the extent that such information has been provided to
the Master Servicer by the Servicers or by the Depositor.

         Section 9.25. Annual Officer's Certificate as to Compliance. (a) The
Master Servicer shall deliver to the Trustee and the Rating Agencies on or
before August 31 of each year, commencing on August 31, 2002, an Officer's
Certificate, certifying that with respect to the period ending on the
immediately preceding December 31; (i) such Servicing Officer has reviewed the
activities of such Master Servicer during the preceding calendar year or
portion thereof and its performance under this Agreement; (ii) to the best of
such Servicing Officer's knowledge, based on such review, such Master Servicer
has performed and fulfilled its duties, responsibilities and obligations under
this Agreement in all material respects throughout such year, or, if there has
been a default in the fulfillment of any such duties, responsibilities or
obligations, specifying each such default known to such Servicing Officer and
the nature and status thereof, (iii) nothing has come to the attention of such
Servicing Officer to lead such Servicing Officer to believe that any Servicer
has failed to perform any of its duties, responsibilities and obligations
under its Servicing Agreement in all material respects throughout such year,
or, if there has been a material default in the performance or fulfillment of
any such duties, responsibilities or obligations, specifying each such default
known to such Servicing Officer and the nature and status thereof, and (iv)
the Master Servicer has received from each Servicer such Servicer's annual
certificate of compliance and a copy of such Servicer's annual audit report,
in each case to the extent required under the applicable Servicing Agreement,
or, if any such certificate or report has not been received by the Master
Servicer, the Master Servicer is using its best reasonable efforts to obtain
such certificate or report.

         (b) Copies of such statements shall be provided to any
Certificateholder upon request, by the Master Servicer or by the Trustee at
the Master Servicer's expense if the Master Servicer failed to provide such
copies (unless (i) the Master Servicer shall have failed to provide the
Trustee with such statement or (ii) the Trustee shall be unaware of the Master
Servicer's failure to provide such statement).

         Section 9.26. Annual Independent Accountants' Servicing Report. If
the Master Servicer has, during the course of any fiscal year, directly
serviced any of the Mortgage Loans, then the Master Servicer at its expense
shall cause a nationally recognized firm of independent certified public
accountants to furnish a statement to the Trustee, the Rating Agencies and the
Depositor on or before August 31 of each year, commencing on August 31, 2002,
to the effect that, with respect to the most recently ended fiscal year, such
firm has examined certain records and documents relating to the Master
Servicer's performance of its servicing obligations under this Agreement and
pooling and servicing and trust agreements in material respects similar to
this Agreement and to each other and that, on the basis of such examination
conducted substantially in compliance with the audit program for mortgages
serviced for FHLMC or the Uniform Single Attestation Program for Mortgage
Bankers, such firm is of the opinion that the Master Servicer's activities
have been conducted in compliance with this Agreement, or that such
examination has disclosed no material items of noncompliance except for (i)
such exceptions as such firm believes to be immaterial, (ii) such other
exceptions as are set forth in such statement and (iii) such exceptions that
the Uniform Single Attestation Program for Mortgage Bankers or the Audit
Program for Mortgages Serviced by FHLMC requires it to report. Copies of such
statements shall be provided to any Certificateholder upon request by the
Master Servicer, or by the Trustee at the expense of the Master Servicer if
the Master Servicer shall fail to provide such copies. If such report
discloses exceptions that are material, the Master Servicer shall advise the
Trustee whether such exceptions have been or are susceptible of cure, and will
take prompt action to do so.

         Section 9.27. Merger or Consolidation. Any Person into which
the Master Servicer may be merged or consolidated, or any Person resulting
from any merger, conversion, other change in form or consolidation to which
the Master Servicer shall be a party, or any Person succeeding to the business
of the Master Servicer, shall be the successor to the Master Servicer
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto, anything herein to the contrary
notwithstanding; provided, however, that the successor or resulting Person to
the Master Servicer shall be a Person that shall be qualified and approved to
service mortgage loans for FNMA or FHLMC and shall have a net worth of not
less than $15,000,000.

         Section 9.28. Resignation of Master Servicer. Except as otherwise
provided in Sections 9.27 and 9.29 hereof, the Master Servicer shall not
resign from the obligations and duties hereby imposed on it unless it or the
Trustee determines that the Master Servicer's duties hereunder are no longer
permissible under applicable law or are in material conflict by reason of
applicable law with any other activities carried on by it and cannot be cured.
Any such determination permitting the resignation of the Master Servicer shall
be evidenced by an Opinion of Counsel that shall be Independent to such effect
delivered to the Trustee. No such resignation shall become effective until the
Trustee shall have assumed, or a successor master servicer shall have been
appointed by the Trustee and until such successor shall have assumed, the
Master Servicer's responsibilities and obligations under this Agreement.
Notice of such resignation shall be given promptly by the Master Servicer to
the Depositor.

         Section 9.29. Assignment or Delegation of Duties by the Master
Servicer. Except as expressly provided herein, the Master Servicer shall not
assign or transfer any of its rights, benefits or privileges hereunder to any
other Person, or delegate to or subcontract with, or authorize or appoint any
other Person to perform any of the duties, covenants or obligations to be
performed by the Master Servicer hereunder; provided, however, that the Master
Servicer shall have the right without the prior written consent of the
Trustee, the Depositor or the Rating Agencies to delegate or assign to or
subcontract with or authorize or appoint an Affiliate of the Master Servicer
to perform and carry out any duties, covenants or obligations to be performed
and carried out by the Master Servicer hereunder. In no case, however, shall
any such delegation, subcontracting or assignment to an Affiliate of the
Master Servicer relieve the Master Servicer of any liability hereunder. Notice
of such permitted assignment shall be given promptly by the Master Servicer to
the Depositor and the Trustee. If, pursuant to any provision hereof, the
duties of the Master Servicer are transferred to a successor master servicer,
the entire amount of the Master Servicing Fees and other compensation payable
to the Master Servicer pursuant hereto, including amounts payable to or
permitted to be retained or withdrawn by the Master Servicer pursuant to
Section 9.21 hereof, shall thereafter be payable to such successor master
servicer.

         Section 9.30. Limitation on Liability of the Master Servicer and
Others. Neither the Master Servicer nor any of the directors, officers,
employees or agents of the Master Servicer shall be under any liability to the
Trustee or the Certificateholders for any action taken or for refraining from
the taking of any action in good faith pursuant to this Agreement, or for
errors in judgment; provided, however, that this provision shall not protect
the Master Servicer or any such person against any liability that would
otherwise be imposed by reason of willful misfeasance, bad faith or negligence
in its performance of its duties or by reason of reckless disregard for its
obligations and duties under this Agreement. The Master Servicer and any
director, officer, employee or agent of the Master Servicer shall be entitled
to indemnification by the Trust Fund and will be held harmless against any
loss, liability or expense incurred in connection with any legal action
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 his or its duties hereunder or by reason of reckless
disregard of his or its obligations and duties hereunder. The Master Servicer
and any director, officer, employee or agent of the Master Servicer may rely
in good faith on any document of any kind prima facie properly executed and
submitted by any Person respecting any matters arising hereunder. The Master
Servicer shall be under no obligation to appear in, prosecute or defend any
legal action that is not incidental to its duties to master service the
Mortgage Loans in accordance with this Agreement and that in its opinion may
involve it in any expenses or liability; provided, however, that the Master
Servicer may in its sole discretion undertake any such action that it may deem
necessary or desirable in respect to this Agreement and the rights and duties
of the parties hereto and the interests of the Certificateholders hereunder.
In such event, the legal expenses and costs of such action and any liability
resulting therefrom shall be expenses, costs and liabilities of the Trust Fund
and the Master Servicer shall be entitled to be reimbursed therefor out of the
Collection Account it maintains as provided by Section 4.02.

         Section 9.31. Indemnification; Third-Party Claims. The Master
Servicer agrees to indemnify the Depositor and the Trustee, and hold them
harmless against any and all claims, losses, penalties, fines, forfeitures,
legal fees and related costs, judgments, and any other costs, liability, fees
and expenses that the Depositor and the Trustee may sustain as a result of the
failure of the Master Servicer to perform its duties and master service the
Mortgage Loans in compliance with the terms of this Agreement. The Depositor
and the Trustee shall immediately notify the Master Servicer if a claim is
made by a third party with respect to this Agreement or the Mortgage Loans
entitling the Depositor or the Trustee to indemnification hereunder, whereupon
the Master Servicer shall assume the defense of any such claim and pay all
expenses in connection therewith, including counsel fees, and promptly pay,
discharge and satisfy any judgment or decree which may be entered against it
or them in respect of such claim.

                                  Article X

                             REMIC ADMINISTRATION

         Section 10.01. REMIC Administration. (a) As set forth in the
Preliminary Statement hereto, the Trustee shall elect REMIC status in
accordance with the REMIC Provisions with respect to each of the Lower Tier
REMIC and the Upper Tier REMIC. The Trustee shall make such elections on Forms
1066 or other appropriate federal tax or information return for the taxable
year ending on the last day of the calendar year in which the Certificates are
issued. For the purposes of such elections, each Lower Tier Interest, other
than the Class LT-R Interest is hereby designated as a regular interest in the
Lower Tier REMIC to which such Lower Tier Interest relates, and each
Certificate, other than the Class R Certificate, is hereby designated as a
regular interest in the Upper Tier REMIC. The Class LT-R Interest is hereby
designated as the sole residual interest in the Lower Tier REMIC. The Class R
Certificate evidences ownership of the Class LT-R Interest and is also hereby
designated as the sole residual interest in the Upper Tier REMIC.

         (b) The Closing Date is hereby designated as the "Startup Day" of
each REMIC within the meaning of section 86OG(a)(9) of the Code. The latest
possible maturity date for purposes of Treasury Regulation 1.860G-1(a)(4), the
"Latest Possible Maturity Date".

         (c) The Trustee shall pay any and all tax related expenses (not
including taxes) of each REMIC, including but not limited to any professional
fees or expenses related to audits or any administrative or judicial
proceedings with respect to such REMIC that involve the Internal Revenue
Service or state tax authorities, but only to the extent that (i) such
expenses are ordinary or routine expenses, including expenses of a routine
audit but not expenses of litigation (except as described in (ii)); or (ii)
such expenses or liabilities (including taxes and penalties) are attributable
to the negligence or willful misconduct of the Trustee in fulfilling its
duties hereunder (including its duties as tax return preparer). The Trustee
shall be entitled to reimbursement of the expenses in clause (i) above from
the Certificate Account.

         (d) The Trustee shall prepare, sign and file, all of each REMIC's
federal and state tax and information returns as such REMIC's direct
representative. The expenses of preparing and filing such returns shall be
borne by the Trustee. If any Disqualified Organization acquires any Ownership
Interest in a Residual Certificate, then the Trustee will upon request provide
to the Internal Revenue Service, and to the persons specified in Sections
860E(e)(3) and (6) of the Code, such information as required in Section
860D(a)(6)(B) of the code needed to compute the tax imposed under Section
860E(e) of the Code on transfers of residual interests to disqualified
organizations.

         (e) The Trustee or its designee shall perform on behalf of each REMIC
all reporting and other tax compliance duties that are the responsibility of
such REMIC under the Code, the REMIC Provisions, or other compliance guidance
issued by the Internal Revenue Service or any state or local taxing authority.
Among its other duties, if required by the Code, the REMIC Provisions, or
other such guidance, the Trustee shall provide (i) to the Treasury or other
governmental authority such information as is necessary for the application of
any tax relating to the transfer of a Residual Certificate to any disqualified
person or organization and (ii) to the Certificateholders such information or
reports as are required by the Code or REMIC Provisions.

         (f) The Trustee, the Master Servicer and the Holders of Certificates
shall take any action or cause the REMIC to take any action necessary to
create or maintain the status of such REMIC as a REMIC under the REMIC
Provisions and shall assist each other as necessary to create or maintain such
status. Neither the Trustee, the Master Servicer nor the Holder of any
Residual Certificate shall take any action, cause the REMIC to take any action
or fail to take (or fail to cause to be taken) any action that, under the
REMIC Provisions, if taken or not taken, as the case may be, could (i)
endanger the status of such REMIC as a REMIC or (ii) result in the imposition
of a tax upon such 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 forth on Section 860G(d) of the Code) (either such event, an
"Adverse REMIC Event") unless the Trustee and the Master Servicer have
received an Opinion of Counsel (at the expense of the party seeking to take
such action) to the effect that the contemplated action will not endanger such
status or result in the imposition of such a tax. In addition, prior to taking
any action with respect to the REMIC or the assets therein, or causing such
REMIC to take any action, which is not expressly permitted under the terms of
this Agreement, any Holder of a Residual Certificate will consult with the
Trustee and the Master Servicer, or their respective designees, in writing,
with respect to whether such action could cause an Adverse REMIC Event to
occur with respect to such REMIC, and no such Person shall take any such
action or cause such REMIC to take any such action as to which the Trustee or
the Master Servicer has advised it in writing that an Adverse REMIC Event
could occur.

         (g) Each Holder of a Residual Certificate shall pay when due any and
all taxes imposed on the related REMIC by federal or state governmental
authorities. To the extent that such Trust taxes are not paid by a Residual
Certificateholder, the Trustee shall pay any remaining REMIC taxes out of
current or future amounts otherwise distributable to the Holder of the
Residual Certificate in such REMIC or, if no such amounts are available, out
of other amounts held in the Collection Account, and shall reduce amounts
otherwise payable to holders of regular interests in such REMIC, as the case
may be.

         (h) The Trustee shall, for federal income tax purposes, maintain
books and records with respect to each REMIC on a calendar year and on an
accrual basis.

         (i) No additional contributions of assets shall be made to any REMIC,
except as expressly provided in this Agreement with respect to Qualified
Substitute Mortgage Loans.

         (j) Neither the Trustee nor the Master Servicer shall enter into any
arrangement by which any REMIC will receive a fee or other compensation for
services.

         (k) Upon the request of any Rating Agency, the Trustee shall deliver
to such Rating Agency an Officer's Certificate stating the Trustee's
compliance with the provisions of this Section 10.01.

         Section 10.02. Prohibited Transactions and Activities. Neither the
Depositor, the Master Servicer nor the Trustee shall sell, dispose of, or
substitute for any of the Mortgage Loans, except in a disposition pursuant to
(i) the foreclosure of a Mortgage Loan, (ii) the bankruptcy of the Trust Fund,
(iii) the termination of each REMIC pursuant to Article VII of this Agreement,
(iv) a substitution pursuant to Article II of this Agreement, or (v) a
repurchase of Mortgage Loans pursuant to Article II of this Agreement, nor
acquire any assets for any REMIC, nor sell or dispose of any investments in
the Certificate Account for gain, nor accept any contributions to the REMIC
after the Closing Date, unless it has received an Opinion of Counsel (at the
expense of the party causing such sale, disposition, or substitution) that
such disposition, acquisition, substitution, or acceptance will not (a) affect
adversely the status of such REMIC as a REMIC or of the Certificates other
than the Residual Certificates as the regular interests therein, (b) affect
the distribution of interest or principal on the Certificates, (c) result in
the encumbrance of the assets transferred or assigned to the Trust Fund
(except pursuant to the provisions of this Agreement) or (d) cause such REMIC
to be subject to a tax on prohibited transactions or prohibited contributions
pursuant to the REMIC Provisions.

         Section 10.03. Indemnification with Respect to Certain Taxes and Loss
of REMIC Status. In the event that a REMIC 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 the Trustee of its duties and obligations
set forth herein, the Trustee shall indemnify the Holder of the Residual
Certificate against any and all losses, claims, damages, liabilities or
expenses ("Losses") resulting from such negligence; provided, however, that
the Trustee shall not be liable for any such Losses attributable to the action
or inaction of the Master Servicer, the Depositor, or the Holder of such
Residual Certificate, as applicable, nor for any such Losses resulting from
misinformation provided by the Holder of such Residual Certificate on which
the Trustee has relied. The foregoing shall not be deemed to limit or restrict
the rights and remedies of the Holder of such Residual Certificate now or
hereafter existing at law or in equity. Notwithstanding the foregoing,
however, in no event shall the Trustee 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 Trustee 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).

         Section 10.04. REO Property. (a) Notwithstanding any other provision
of this Agreement, the Master Servicer, acting on behalf of the Trustee
hereunder, shall not (except to the extent provided in the applicable
Servicing Agreement), permit any Servicer to, rent, lease, or otherwise earn
income on behalf of any REMIC with respect to any REO Property which might
cause such REO Property to fail to qualify as "foreclosure" property within
the meaning of section 860G(a)(8) of the Code or result in the receipt by any
REMIC of any "income from non-permitted assets" within the meaning of section
860F(a)(2) of the Code or any "net income from foreclosure property" which is
subject to tax under the REMIC Provisions unless the Master Servicer has
advised, or has caused the applicable Servicer to advise, the Trustee in
writing to the effect that, under the REMIC Provisions, such action would not
adversely affect the status of the REMIC as a REMIC and any income generated
for such REMIC by the REO Property would not result in the imposition of a tax
upon such REMIC.

         (b) The Master Servicer shall make, or shall cause the applicable
Servicer to make, reasonable efforts to sell any REO Property for its fair
market value. In any event, however, the Master Servicer shall, or shall cause
the applicable Servicer to, dispose of any REO Property within three years
from the end of the calendar year of its acquisition by the Trust Fund unless
the Trustee has received a grant of extension from the Internal Revenue
Service to the effect that, under the REMIC Provisions and any relevant
proposed legislation and under applicable state law, the REMIC may hold REO
Property for a longer period without adversely affecting the REMIC status of
such REMIC or causing the imposition of a Federal or state tax upon such
REMIC. If the Trustee has received such an extension, then (a) the Trustee
shall provide a copy of such extension to the Master Servicer and (b) the
Trustee, or the Master Servicer, acting on its behalf hereunder, shall, or
shall cause the applicable Servicer to, continue to attempt to sell the REO
Property for its fair market value for such period longer than three years as
such extension permits (the "Extended Period"). If the Trustee has not
received such an extension and the Trustee, or the Master Servicer acting on
behalf of the Trustee hereunder, or the applicable Servicer is unable to sell
the REO Property within 33 months after its acquisition by the Trust Fund or
if the Trustee has received such an extension, and the Trustee, or the Master
Servicer acting on behalf of the Trustee hereunder, is unable to sell the REO
Property within the period ending three months before the close of the
Extended Period, the Master Servicer shall, or shall cause the applicable
Servicer to, before the end of the three year period or the Extended Period,
as applicable, (i) purchase such REO Property at a price equal to the REO
Property's fair market value or (ii) auction the REO Property to the highest
bidder (which may be the Master Servicer) in an auction reasonably designed to
produce a fair price prior to the expiration of the three-year period or the
Extended Period, as the case may be.

         Section 11.02. Entire Agreement. This Agreement contains the entire
agreement and understanding among the parties hereto with respect to the
subject matter hereof, and supersedes all prior and contemporaneous
agreements, understandings, inducements and conditions, express or implied,
oral or written, of any nature whatsoever with respect to the subject matter
hereof. The express terms hereof control and supersede any course of
performance and/or usage of the trade inconsistent with any of the terms
hereof.

         Section 11.03. Amendment. (a) This Agreement may be amended from time
to time by the Depositor, the Master Servicer and the Trustee, without notice
to or the consent of any of the Holders, (i) to cure any ambiguity, (ii) to
cause the provisions herein to conform to or be consistent with or in
furtherance of the statements made with respect to the Certificates, the Trust
Fund or this Agreement in any Offering Document; or to correct or supplement
any provision herein which may be inconsistent with any other provisions
herein, (iii) to make any other provisions with respect to matters or
questions arising under this Agreement or (iv) to add, delete, or amend any
provisions to the extent necessary or desirable to comply with any
requirements imposed by the Code and the REMIC Provisions. No such amendment
effected pursuant to the preceding sentence shall, as evidenced by an Opinion
of Counsel, adversely affect the status of any REMIC created pursuant to this
Agreement, nor shall such amendment effected pursuant to clause (iii) of such
sentence adversely affect in any material respect the interests of any Holder.
Prior to entering into any amendment without the consent of Holders pursuant
to this paragraph, the Trustee may require an Opinion of Counsel (at the
expense of the party requesting such amendment) to the effect that such
amendment is permitted under this paragraph. Any such amendment shall be
deemed not to adversely affect in any material respect any Holder, if the
Trustee receives written confirmation from each Rating Agency that such
amendment will not cause such Rating Agency to reduce, qualify or withdraw the
then current rating assigned to the Certificates (and any Opinion of Counsel
requested by the Trustee in connection with any such amendment may rely
expressly on such confirmation as the basis therefor).

         (b) This Agreement may also be amended from time to time by the
Depositor, the Master Servicer and the Trustee with the consent of the Holders
of not less than 66 2/3% of the Class Principal Amount (or Percentage
Interest) of each Class of Certificates affected thereby for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Agreement or of modifying in any manner the rights of the
Holders; provided, however, that no such amendment shall be made unless the
Trustee receives an Opinion of Counsel, at the expense of the party requesting
the change, that such change will not adversely affect the status of the REMIC
as a REMIC or cause a tax to be imposed on such REMIC; and provided further,
that no such amendment may (i) reduce in any manner the amount of, or delay
the timing of, payments received on Mortgage Loans which are required to be
distributed on any Certificate, without the consent of the Holder of such
Certificate or (ii) reduce the aforesaid percentages of Class Principal Amount
(or Percentage Interest) of Certificates of each Class, the Holders of which
are required to consent to any such amendment without the consent of the
Holders of 100% of the Class Principal Amount (or Class Notional Amount) of
each Class of Certificates affected thereby. For purposes of this paragraph,
references to "Holder" or "Holders" shall be deemed to include, in the case of
any Class of Book-Entry Certificates, the related Certificate Owners.

         (c) Promptly after the execution of any such amendment, the Trustee
shall furnish written notification of the substance of such amendment to each
Holder, the Depositor and to the Rating Agencies.

         (d) It shall not be necessary for the consent of Holders under this
Section 11.03 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 Holders shall be subject to such reasonable regulations
as the Trustee may prescribe.

         (e) Notwithstanding anything to the contrary in any Servicing
Agreement, the Trustee shall not consent to any amendment of any Servicing
Agreement except pursuant to the standards provided in this Section with
respect to amendment of this Agreement.

         Section 11.04. Voting Rights. Except to the extent that the consent
of all affected Certificateholders is required pursuant to this Agreement,
with respect to any provision of this Agreement requiring the consent of
Certificateholders representing specified percentages of aggregate outstanding
Certificate Principal Amount (or Notional Amount), Certificates owned by the
Depositor, the Master Servicer, the Trustee or any Servicer or Affiliates
thereof are not to be counted so long as such Certificates are owned by the
Depositor, the Master Servicer, the Trustee or any Servicer or Affiliates
thereof.

         Section 11.05. Provision of Information. (a) For so long as any of
the Certificates of any Series or Class are "restricted securities" within the
meaning of Rule 144(a)(3) under the Act, each of the Depositor and the Trustee
agree to cooperate with each other to provide to any Certificateholders and to
any prospective purchaser of Certificates designated by such
Certificateholder, upon the request of such Certificateholder or prospective
purchaser, any information required to be provided to such holder or
prospective purchaser to satisfy the condition set forth in Rule 144A(d)(4)
under the Act. Any reasonable, out-of-pocket expenses incurred by the Trustee
in providing such information shall be reimbursed by the Depositor.

         (b) The Trustee will provide to any person to whom a Prospectus was
delivered, upon the request of such person specifying the document or
documents requested, (i) a copy (excluding exhibits) of any report on Form 8-K
or Form 10-K filed with the Securities and Exchange Commission pursuant to
Section 6.20(c) and (ii) a copy of any other document incorporated by
reference in the Prospectus. Any reasonable out-of-pocket expenses incurred by
the Trustee in providing copies of such documents shall be reimbursed by the
Depositor.

         (c) On each Distribution Date, the Trustee shall deliver or cause to
be delivered by first class mail to the Depositor, Attention: Contract
Finance, a copy of the report delivered to Certificateholders pursuant to
Section 4.03.

ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AND THE OBLIGATIONS, RIGHTS
AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH

         Section 11.13. Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall be deemed to be an original, and all of
which together shall constitute one and the same instrument.

         Section 11.14. Transfer of Servicing. The Seller agrees that it
shall provide written notice to the Trustee and the Master Servicer thirty
days prior to any transfer or assignment by the Seller of its rights under any
Servicing Agreement or of the servicing thereunder or delegation of its rights
or duties thereunder or any portion thereof to any Person other than the
initial Servicer under such Servicing Agreement; provided that the Seller
shall not be required to provide prior notice of any transfer of servicing
that occurs within three months following the Closing Date to an entity that
is a Servicer on the Closing Date. In addition, the ability of the Seller to
transfer or assign its rights and delegate its duties under a Servicing
Agreement or to transfer the servicing thereunder to a successor servicer
shall be subject to the following conditions:

               (i) Such successor servicer must be qualified to service loans
          for FNMA or FHLMC;

              (ii) Such successor servicer must satisfy the
          seller/servicer eligibility standards in the applicable Servicing
          Agreement, exclusive of any experience in mortgage loan origination,
          and must be reasonably acceptable to the Master Servicer, whose
          approval shall not be unreasonably withheld;

             (iii) Such successor servicer must execute and deliver to
          the Trustee and the Master Servicer an agreement, in form and
          substance reasonably satisfactory to the Trustee and the Master
          Servicer, that contains an assumption by such successor servicer of
          the due and punctual performance and observance of each covenant and
          condition to be performed and observed by the applicable Servicer
          under the applicable Servicing Agreement or, in the case of a
          transfer of servicing to a party that is already a Servicer pursuant
          to this Agreement, an agreement to add the related Mortgage Loans to
          the Servicing Agreement already in effect with such Servicer;

               (iv) If the successor servicer is not a Servicer of
          Mortgage Loans at the time of such transfer, there must be delivered
          to the Trustee a letter from each Rating Agency to the effect that
          such transfer of servicing will not result in a qualification,
          withdrawal or downgrade of the then-current rating of any of the
          Certificates;

               (v) The Seller shall, at its cost and expense, take such steps,
          or cause the terminated Servicer to take such steps, as may be
          necessary or appropriate to effectuate and evidence the transfer of
          the servicing of the Mortgage Loans to such successor servicer,
          including, but not limited to, the following: (A) to the extent
          required by the terms of the Mortgage Loans and by applicable
          federal and state laws and regulations, the Seller shall cause the
          prior Servicer to timely mail to each obligor under a Mortgage Loan
          any required notices or disclosures describing the transfer of
          servicing of the Mortgage Loans to the successor servicer; (B) prior
          to the effective date of such transfer of servicing, the Seller
          shall cause the prior Servicer to transmit to any related insurer
          notification of such transfer of servicing; (C) on or prior to the
          effective date of such transfer of servicing, the Seller shall cause
          the prior Servicer to deliver to the successor servicer all Mortgage
          Loan Documents and any related records or materials; (D) on or prior
          to the effective date of such transfer of servicing, the Seller
          shall cause the prior Servicer to transfer to the successor
          servicer, or, if such transfer occurs after a Remittance Date but
          before the next succeeding Deposit Date, to the Master Servicer, all
          funds held by the applicable Servicer in respect of the Mortgage
          Loans; (E) on or prior to the effective date of such transfer of
          servicing, the Seller shall cause the prior Servicer to, after the
          effective date of the transfer of servicing to the successor
          servicer, continue to forward to such successor servicer, within one
          Business Day of receipt, the amount of any payments or other
          recoveries received by the prior Servicer, and to notify the
          successor servicer of the source and proper application of each such
          payment or recovery; and (F) the Seller shall cause the prior
          Servicer to, after the effective date of transfer of servicing to
          the successor servicer, continue to cooperate with the successor
          servicer to facilitate such transfer in such manner and to such
          extent as the successor servicer may reasonably request.

         Section 11.15. Limitations on Actions; No Proceedings. (a) Other than
pursuant to this Agreement, or in connection with or incidental to the
provisions or purposes of this Agreement, the trust created hereunder shall
not (i) issue debt or otherwise borrow money, (ii) merge or consolidate with
any other entity or transfer all or substantially all of its assets to any
other entity, or (iii) otherwise engage in any activity or exercise any power
not provided for in this Agreement.

         (b) Notwithstanding any prior termination of this Agreement, the
Trustee, the Master Servicer and the Depositor shall not, prior to the date
which is one year and one day after the termination of this Agreement,
acquiesce, petition or otherwise invoke or cause any Person to invoke the
process of any court or government authority for the purpose of commencing or

Dear Sirs:


         In connection with our proposed purchase of $______________ principal
amount of Structured Asset Securities Corporation Mortgage Pass-Through
Certificates, Series 2001-7A (the "Privately Offered Certificates") of
Structured Asset Securities Corporation (the "Depositor"), we confirm that:

(1)      We understand that the Privately Offered Certificates have not
         been, and will not be, registered under the Securities Act of 1933,
         as amended (the "Securities Act"), and may not be sold except as
         permitted in the following sentence. We agree, on our own behalf and
         on behalf of any accounts for which we are acting as hereinafter
         stated, that if we should sell any Privately Offered Certificates
         within two years of the later of the date of original issuance of the
         Privately Offered Certificates or the last day on which such
         Privately Offered Certificates are owned by the Depositor or any
         affiliate of the Depositor (which includes the Placement Agent) we
         will do so only (A) to the Depositor, (B) to "qualified institutional
         buyers" (within the meaning of Rule 144A under the Securities Act) in
         accordance with Rule 144A under the Securities Act ("QIBs"), (C)
         pursuant to the exemption from registration provided by Rule 144
         under the Securities Act, or (D) to an institutional "accredited
         investor" within the meaning of Rule 501(a)(1), (2), (3) or (7) of
         Regulation D under the Securities Act that is not a QIB (an
         "Institutional Accredited Investor") which, prior to such transfer,
         delivers to the Trustee under the Trust Agreement dated as of April
         1, 2001 among the Depositor, Aurora Loan Services Inc., as Master
         Servicer and The Chase Manhattan Bank, as Trustee (the "Trustee"), a
         signed letter in the form of this letter; and we further agree, in
         the capacities stated above, to provide to any person purchasing any
         of the Privately Offered Certificates from us a notice advising such
         purchaser that resales of the Privately Offered Certificates are
         restricted as stated herein.

(2)      We understand that, in connection with any proposed resale of
         any Privately Offered Certificates to an Institutional Accredited
         Investor, we will be required to furnish to the Trustee and the
         Depositor a certification from such transferee in the form hereof to
         confirm that the proposed sale is being made pursuant to an exemption
         from, or in a transaction not subject to, the registration
         requirements of the Securities Act. We further understand that the
         Privately Offered Certificates purchased by us will bear a legend to
         the foregoing effect.

(3)      We are acquiring the Privately Offered Certificates for
         investment purposes and not with a view to, or for offer or sale in
         connection with, any distribution in violation of the Securities Act.
         We have such knowledge and experience in financial and business
         matters as to be capable of evaluating the merits and risks of our
