<PAGE>

         This TRUST AGREEMENT, dated as of January 1, 2004 (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 CITIBANK, N.A., a national banking association, as
trustee (the "Trustee").

                              PRELIMINARY STATEMENT

         The Depositor has acquired the Mortgage Loans from the 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 and the Class A-IO2 Certificates, is hereby designated as a
regular interest in the Upper Tier REMIC for purposes of the REMIC Provisions.
Each of the Class A-IO2 Components is hereby designated as a regular interest 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 each
of 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 REMIC Regular Interests. Each Lower Tier REMIC Regular
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 REMIC Interest Interests.

         The Lower Tier REMIC

         The following table specifies the class designation, initial principal
balance, pass-through rate and related Certificates or Class A-IO2 Components
for each class of Lower Tier REMIC Interest.

1.   The Class LT-AIO1 Interest shall have a notional balance, rather than a
     principal balance. For federal income tax purposes, the Class LT-AIO1
     Interest shall be entitled to a specified portion of the interest payable
     on each Non-Discount Mortgage Loan equal to the excess of the Net Mortgage
     Rate over the Designated Rate.

2.   The Class LT-R Interest shall represent the sole class of residual interest
     in the Lower Tier REMIC. The Class LT-R Interest will not have a principal
     amount or interest rate. The Class LT-R Interest shall be represented by
     the Class R Certificate.

         Payments of principal and interest shall be made on the Lower Tier
REMIC Interests in the same amounts as such payments are made on the
Corresponding Certificates and Class A-IO2 Components (without regard to
payments made under Section 5.02(d)) and Realized Losses and shortfalls shall be
allocated to the Lower Tier REMIC Interests in the same amounts as such Realized
Losses and shortfalls are allocated to the Corresponding Certificates and Class
A-IO2 Components. Subordinate Certificate Writedown Amounts shall be borne by
each Class of Lower Tier REMIC Interest in an amount equal to the Subordinate
Certificate Writedown Amount, if any, for the Corresponding Class of
Certificates. For purposes of allocating Realized Losses and shortfalls to the
Class LT-A1 Interest, the Class LT-A2 Interest, the Class LT-A3

Interest and the Class LT-A4 Interest, Realized Losses and shortfalls allocated
to the Class A-IO2 Interest on any Distribution Date will be allocated among the
Class A-IO2 Components pro rata in accordance with the current accrued interest
on the Class A-IO2 Components for such Distribution Date.

         The Upper Tier REMIC

         When reference is made herein to the "ranking" of a Certificate, the
highest ranking Certificate is the Certificate with the lowest numerical
designation and the lowest ranking Certificate is the Certificate with the

         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

<PAGE>

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

not obtain title to or beneficial ownership of any Additional Collateral as a

         (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

         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

         Depositor shall deliver or cause to be delivered to the Trustee (or its

         recording office, or, in the case of a Mortgage that has been lost, a

         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

         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;

         mortgage or equivalent executed in connection with the Mortgage or as

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.

Loan other than a Cooperative Loan shall be recorded; provided, however, that

be from 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

Mortgaged Property.

         at the expense of the Depositor and with the cooperation of the
         applicable Servicer, shall cause to be taken such actions by such
         Servicer 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 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

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

                                       40
<PAGE>

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.

         (g) Each of the parties hereto acknowledge and agree that it is not
intended that any Mortgage Loan be included in the Trust Fund that is a
"High-Cost Home Loan" as defined in the New Jersey Home Ownership Act effective
November 27, 2003.

         Section 2.03.  Representations and Warranties of the Depositor.
                        -----------------------------------------------

         (a) The Depositor hereby represents and warrants to the Trustee, for
the benefit of Certificateholders, and to the Master Servicer, as of the Closing
Date or such other date as is specified, that:

                  (i)      the Depositor is a corporation duly organized,
         validly existing and in good standing under the laws governing its
         creation and existence and has full corporate power and authority to
         own its property, to carry on its business as presently conducted, to
         enter 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

                                       41
<PAGE>

         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 Brothers Holdings 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

                                       42
<PAGE>

Transferor under any applicable representation or warranty made by it. The
Trustee acknowledges that Lehman Brothers Holdings 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 and (ii) of Lehman Brothers Holdings 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 Brothers Holdings 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, Lehman Brothers Holdings and assigned to the Trustee, the
Depositor, such Transferor, Lehman Brothers Holdings 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 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 Brothers Holdings 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 Brothers Holdings 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 Master Servicer in
respect of such repurchase of a Mortgage Loan will be considered a Principal
Prepayment and shall be deposited in the Collection Account pursuant to Section
4.01. The Trustee, upon receipt of the full amount of the Purchase Price for a
Deleted

                                       43
<PAGE>

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 Brothers Holdings 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, Lehman Brothers Holdings, 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 by such Servicer 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. The Depositor shall cause the
Mortgage Loan Schedule to be amended in accordance with the terms of this
Agreement.

         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;

                                       44
<PAGE>

(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.

                                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. 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.

                                       46
<PAGE>

         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.

         (d) The Class B4, Class B5 or Class B6 Certificates sold to an
"accredited investor" under Rule 501(a)(1), (2), (3) or (7) under the Act shall
be issued initially in the form of one or more Definitive Certificates.

         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.

                                       47
<PAGE>

         (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) and (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

                                       48
<PAGE>

                  (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) 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 transaction provisions of ERISA, Section 4975 of the
Code or substantially similar rules under state, local or other federal law
("Similar Law") 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 of Counsel to the effect that the purchase and holding
of an ERISA-Restricted Certificate (other than the Class R 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, Section 4975 of the Code or Similar Law. 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.

         The Trustee shall have no obligations to monitor transfers of
Book-Entry Certificates that are ERISA-Restricted Certificates and shall have no
liability for transfers of such Certificates in violation of the transfer
restrictions.

         Notwithstanding anything to the contrary herein, any purported transfer
of an ERISA-Restricted Certificate in the form of a Definitive Certificate to or
on behalf of an employee benefit plan subject to Title I of ERISA, a plan
subject to Section 4975 of the Code or a plan subject to Similar Law without the
delivery to the Trustee of an Opinion of Counsel satisfactory to the Trustee as
described above shall be void and of no effect. The Trustee shall be under no
liability to any Person for any registration of transfer of any ERISA-Restricted
Certificate that is in fact not permitted by this Section 3.03(d) or for making
any payments due on such Certificate to the Holder thereof or taking any other
action with respect to such Holder under the provisions of this Agreement so
long as the transfer was registered in accordance with the foregoing
requirements. The Trustee shall be entitled, but not obligated, to recover from
any Holder of any ERISA-Restricted Certificate that was in fact an employee
benefit plan subject to Title I of ERISA, a plan subject to Section 4975 of the
Code or a plan subject to Similar Law, or a Person acting on behalf of any such
plan at the time it became a Holder or, at such subsequent time as it became
such a plan or Person acting on behalf of such a plan, all payments made on such
ERISA-Restricted Certificate at and after either such time. Any such payments so
recovered by the Trustee shall be paid and delivered by the Trustee to the last
preceding Holder of such Certificate that is not such a plan or Person acting on
behalf of a plan.

                                       49

         (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, in the case of clause (ii),
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

                                       50
<PAGE>

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 any 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).

                  (i)      Subject to clauses (ii) and (iii) of this Section
         3.03(h), transfers of a Global Security representing any 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.

                  (ii)     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

                                       51
<PAGE>

         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.

                  (iii)    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.

                  (iv)     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.

                  (v)      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)(iii).

         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.

                                       53
<PAGE>

         (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 Certificate 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;

                                       54
<PAGE>

                  (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.

                        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 2004-5H." 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.

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

(G) of paragraph (i) of the definition thereof (other than any amounts due or
reimbursable to the Trustee pursuant to this Agreement), 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

         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 Master Servicer in
trust for the benefit of the Trustee and Holders of Structured Asset Securities
Corporation, Mortgage Pass-Through Certificates, Series 2004-5H. All income and
gain realized from any such investment shall be for the benefit of the Master
Servicer, while such Collection Account is maintained by the Master Servicer,
and shall be subject to its withdrawal or order from time to time 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.

                        ----------------------------------------------

         The Master Servicer may, from time to time, make, or cause to be made,
withdrawals from the Collection Account for the following purposes:

<PAGE>

                  (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
         previously unreimbursed Advances or Servicing Advances made by it or by
         such Servicer that it or such Servicer 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;

<PAGE>

                  (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.

         If provided in the related Servicing Agreement, each Servicer shall be
entitled to retain as additional servicing compensation any Prepayment Interest
Excess (to the extent not offset by Prepayment Interest Shortfalls). The
Servicer of the Participations shall be entitled to retain as additional
servicing compensation any Prepayment Penalty Amounts received with respect to
the Participations.

         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).

containing the same information in an alternative format) available each month
to Certificateholders and the Rating Agencies via the Trustee's internet
website. The Trustee's internet website shall initially be located at
"www.sf.citidirect.com." Assistance in using the website can be obtained by
calling the Trustee at (212) 657-7781. Such parties that are unable to use the
website are entitled to have a paper copy mailed to them via first class mail by
calling the customer service desk and indicating such. The Trustee shall have
the right to change the way such statements are distributed in order to make
such distribution more convenient and/or more accessible to the above parties
and the Trustee shall provide timely and adequate notification to all above
parties regarding any such changes.

         The foregoing information and reports shall be prepared and determined
by the Trustee based solely on Mortgage Loan data provided to the Trustee by the

In preparing or furnishing the Mortgage Loan data to the Trustee, the Master
Servicer shall be entitled to rely conclusively on the accuracy of the
information or data regarding the Mortgage Loans and the related REO Property
that has

                                       61
<PAGE>

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 entitled to conclusively rely on the
Mortgage Loan data provided by the Master Servicer and shall have no liability
for any errors in such Mortgage Loan data.

         (b) Upon the reasonable advance written request of any
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; provided, however, that the Master Servicer
shall be entitled to be reimbursed 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
statute or regulation, after the end of each calendar year, the Trustee shall,
upon written request, send to each Person who at any time during the calendar
year was a 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 Mortgage Loan level
information as is necessary for the Trustee to prepare such reports.

         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:

                                       62
<PAGE>

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

                  (ii)     to pay the Trustee 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 paid to 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.

                                    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, a Percentage Interest of 25%, 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

                                       63
<PAGE>

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 with respect to the Mortgage Pool, and shall distribute such
amount to the Holders of record of each Class of Certificates, in the following
order of priority:

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

                  (ii)     from the remaining Available Distribution Amount, to
         each Class of Senior Certificates (other than the Class A-PO
         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;
         provided, however, that any shortfall in available amounts shall be
         allocated among the Senior Classes in proportion to the amount of

         Section 5.03.  Allocation of Realized Losses.
                        -----------------------------

         (a) On any Distribution Date, (x) the applicable PO Percentage of the
principal portion of each Realized Loss (including any Realized Loss that is an
Excess Loss) in respect of a Mortgage Loan will be allocated to the Class A-PO
Certificates until the Class Principal Amount thereof has been reduced to zero;
and (y) the Non-PO Percentage of the principal portion of each Realized Loss
(other than any Excess Loss) in respect of a Mortgage Loan shall be allocated as
described below:

                           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;

                                       67
<PAGE>

                           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 Class A1, Class A2, Class A3, Class
                  A4 and Class R Certificates, pro rata, until the Class
                  Principal Amounts thereof have been reduced to zero.

         Notwithstanding the foregoing, the first $0.03 of the applicable Non-PO
Percentage of the principal portion of a Realized Loss shall not be allocated to
any Class of Certificates.

         (b) With respect to any Distribution Date, the applicable Non-PO
Percentage of the principal portion of any Excess Loss shall be allocated, pro
rata, to the Subordinate Certificates and the Senior Certificates (other than
the Class A-PO Certificates), in proportion to their 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 or Component of
Certificates pursuant to Section 5.03(a) or (b) shall be allocated among the
Certificates of such Class or Component in proportion to their respective
Certificate Principal Amounts or Component Principal Amounts. Any allocation of
Realized Losses pursuant to this paragraph (c) shall be accomplished by reducing
the Certificate Principal Amount or Component 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.

         (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

                                       68
<PAGE>

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 the Master Servicer and the 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(a) 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

                                       69
<PAGE>

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 Master Servicer shall not be responsible for making any
Compensating Interest Payments not made by the Servicers. Any Compensating
Interest Payments made by the Servicers shall be a component of the Interest
Remittance Amount.

                                   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
the Trustee 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

                                       70
<PAGE>

         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;

                  (iii)    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 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 address provided in Section 11.07, and such notice references the
         Holders of the Certificates and this Agreement; and

                  (iv)     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, with respect to the Trustee,
         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

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

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. The predecessor trustee (or its custodian) shall deliver to
the successor trustee (or assign to the successor trustee its interest under
each Custodial Agreement, to the extent permitted thereunder) all Mortgage Files
and documents and statements related to each Mortgage Files 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

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

of any paper or any further act on the part of any of the parties hereto,
anything herein to

                                       75

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

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

         than 50% of the Aggregate Voting Interests of the Certificates may at
         any time accept the resignation of or remove any separate trustee,

         resignation or removal does not violate the other terms of this
         Agreement.

                                       76
<PAGE>

         (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

                                       77
<PAGE>

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 to the extent provided in Section
6.12.

         Section 6.11. Indemnification of Trustee. The Trustee and its
respective 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 or 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 or in connection
with the performance of their duties hereunder, including any applicable fees
and expenses payable pursuant to Section 6.12 and 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 that failure to so notify shall not relieve the Trust Fund of
         the obligation to indemnify the Trustee; 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 the obligation
         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.

                                       78
<PAGE>

         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 and Custodian. The Trustee
shall be entitled to (a) the Trustee Fee and (b) all reasonable expenses,
disbursements and advancements incurred or made by the Trustee in accordance
with this Agreement (including fees and expenses of its counsel and all persons
not regularly in its employment), except any such expenses, disbursements and
advancements that either (i) arise from its negligence, bad faith or willful
misconduct or (ii) do not constitute "unanticipated expenses" within the meaning
of Treasury Regulations Section 1.860G-1(b)(3)(ii). The Custodian shall be
compensated as separately agreed with the Depositor.

         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":

         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

         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)     The Master Servicer has notice or actual knowledge
         that 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 60 days of the absence of the date the Master Servicer
         receives such notice or actual knowledge; or

                                       80
<PAGE>

                  (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, which such failure continues unremedied
         for a period of one Business Day after the date upon which notice of
         such failure shall have been given to the Master Servicer by the
         Trustee.

         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, so long as such Event of Default shall not have been
remedied within the time period prescribed by clause (x) of this Section 6.14,
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. 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 Servicers 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. The Trustee
shall be entitled to be reimbursed from the Master Servicer (or by the Trust
Fund, if the Master Servicer is unable to fulfill its obligations hereunder) for
all costs associated with the transfer of servicing from the predecessor Master
Servicer, including, without limitation, any costs or expenses associated with
the complete transfer of all servicing data and the completion, correction or
manipulation of such servicing

                                       81
<PAGE>

data as may be required by the Trustee to correct any errors or insufficiencies
in the servicing data or otherwise to enable the Trustee to master service the
Mortgage Loans properly and effectively. If the terminated Master Servicer does
not pay such reimbursement within thirty (30) days of its receipt of an invoice
therefor, such reimbursement shall be an expense of the Trust and the Trustee
shall be entitled to withdraw such reimbursement from amounts on deposit in the
Certificate Account pursuant to Section 4.04; provided that the terminated
Master Servicer shall reimburse the Trust for any such expense incurred by the
Trust Fund.

         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) Within 90 days of 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 9.28, 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 or the Trustee'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 within a period of time not to exceed 90 days after
the issuance of any notice of termination pursuant to Section 6.14(a) or Section
9.28. The Trustee 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

                                       82
<PAGE>

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

                                       83
<PAGE>

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 a Responsible Officer of the
Trustee, give written notice thereof to the 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.
                        --------------------------------------------

                                       84
<PAGE>

         (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
shall file any other documents to the extent required by applicable state tax
law (to the extent such documents are in the Trustee's possession). The Trustee
shall forward copies to the Depositor of all such returns and Form 1099
supplemental tax 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 distribute to Certificateholders
Form 1099 (supplemental tax information) (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, as applicable, resulting from any error in any of such tax
or information returns directly resulting from errors in the information
provided by such Master Servicer.

         (b) The Trustee shall prepare and file with the Internal Revenue
Service ("IRS"), on behalf of each of the Lower Tier REMIC and the Upper Tier
REMIC, an application on IRS Form SS-4. The Trustee, upon receipt from the IRS
of the Notice of Taxpayer Identification Number Assigned for each REMIC, shall
promptly forward copies of such notice to the Master Servicer and the Depositor.
The Trustee will file, on behalf of each REMIC, an IRS Form 8811.

         (c) The Depositor shall prepare or cause to be prepared the initial
current report on Form 8-K. Thereafter, within 15 days after each Distribution
Date, the Trustee shall, in accordance with industry standards, file with the
Securities and Exchange Commission (the "Commission") via the Electronic Data
Gathering and Retrieval System (EDGAR), a Form 8-K with a copy of the statement
to the Certificateholders for such Distribution Date as an exhibit thereto.
Prior to January 31, 2005, the Trustee shall, in accordance with industry
standards, file a Form 15 Suspension Notification with respect to the Trust
Fund, if applicable. Prior to March 31, 2005, the Trustee shall file (but will
not execute) a Form 10-K, in substance conforming to industry standards, with
respect to the Trust Fund. The Depositor hereby grants to the Trustee a limited
power of attorney to execute and file each such document on behalf of the
Depositor. Such power of attorney shall continue until either the earlier of (i)
receipt by the Trustee from the Depositor of written termination of such power
of attorney and (ii) the termination of the Trust Fund. The Depositor agrees to
promptly furnish to the Trustee, from time to time upon request, such further
information, reports, and financial statements within its control related to
this Agreement and the Mortgage Loans as the Trustee reasonably deems
appropriate to prepare and file all necessary reports with the Commission. In
addition, the Form 10-K shall include the certification required pursuant to
Rule 13a-14 under the Securities and Exchange Act of 1934, as amended (the "Form
10-K Certification") signed by an appropriate party or parties (which Form 10-K
Certification the Trustee shall not be required to sign). The Trustee shall have
no responsibility to file any items other than those specified in this section.

         (d) If so requested, the Trustee shall sign a certification (in the
form attached hereto as Exhibit M) for the benefit of the Person(s) signing the
Form 10-K Certification regarding certain aspects of such Form 10-K
Certification (provided, however, that the Trustee shall not be

                                       85
<PAGE>

required to undertake an analysis of the accountant's report attached as an
exhibit to the Form 10-K).

         (e) If so requested, the Master Servicer shall sign a certification (in
the form attached hereto as Exhibit N) for the benefit of the Person(s) signing
the Form 10-K Certification regarding certain aspects of such Form 10-K
Certification (provided, however, that the Master Servicer shall not be required
to undertake an analysis of the accountant's report attached as an exhibit to
the Form 10-K).

         (f) Each person (including their officers or directors) that signs any
Form 10-K Certification shall be entitled to indemnification from the Trust Fund
for any liability or expense incurred by it in connection with such
certification, other than any liability or expense attributable to such Person's
own bad faith, negligence or willful misconduct. The provisions of this
subsection shall survive any termination of this Agreement and the resignation
or removal of such Person.

                            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 4.02 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 in the Trust Fund is
less than 5% of the Principal Balance of the Mortgage Loans in the Trust Fund
(determined in the aggregate rather than by pool) as of the Cut-off Date, the
Master Servicer, with the consent of the Seller (which consent will not be
unreasonably withheld), may, upon written direction to the Trustee, cause the
Trustee to sell (or arrange for the sale of) the assets of the Trust Fund. Upon
the repurchase of the Mortgage Loans in the Trust Fund, the Master Servicer
shall, upon written direction to the

                                       86
<PAGE>

Trustee, cause each REMIC included in 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 "Repurchase Price")
equal to: (i) 100% of the unpaid principal balance of each Mortgage Loan in the
Trust Fund 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 such Distribution Date, (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 in the Trust
Fund. The Master Servicer, each Servicer (or the Trustee, if applicable) shall
be reimbursed from the Repurchase Price for any Mortgage Loan or related REO
Property for any Advances or Servicing Advances made with respect to the
Mortgage Loans that are reimbursable to the Master Servicer under this Agreement
or the related Servicing Agreement (or to the Trustee hereunder), together with
any accrued and unpaid compensation and any other amounts due to the Master
Servicer and the Trustee hereunder or the Servicers thereunder. The Trustee
shall distribute the assets of the Trust Fund on the Distribution Date on which
the repurchase occurred. Upon the repurchase of the Mortgage Loans, the Trust
Fund shall terminate in accordance with the terms of this Agreement.

         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 Master Servicer, 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

                                       87
<PAGE>

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, but only to the extent that
such expenses constitute "unanticipated expenses" within the meaning of Treasury
Regulations Section 1.860G-1(b)(3)(ii).

         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 and each REMIC; and

                  (ii)     The Trustee shall attach a statement to the final
         Federal income tax return for each 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

                                       88
<PAGE>

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

                                       89
<PAGE>

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 the Trustee, the Master Servicer and the Depositor
shall not 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

                                       90
<PAGE>

Trustee or the Master Servicer in reliance thereon, whether or not notation of
such action is made upon such Certificate.

                 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

                                       91
<PAGE>

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 the last day of February of each
year commencing on February 28, 2005. 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 any REMIC included in 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

                                       92
<PAGE>

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 or the Servicer, upon request, with any powers
of attorney prepared by the Master Servicer or such Servicer empowering the
Master Servicer or such 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 the Mortgage Loans and carry out its duties
hereunder, and to allow each Servicer to service the Mortgage Loans, 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 exercise the same care that it
customarily employs and exercises in master servicing and administering loans
for its own account, giving due consideration to Accepted Servicing Practices
where such practices do not conflict with this 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 make or knowingly
permit any modification, waiver or amendment of any material term of any
Mortgage Loan unless: (1) such Mortgage Loan is in default or default by the
related Mortgagor is, in the reasonable judgment of the Master Servicer or the
applicable Servicer, reasonably foreseeable, (2) in the case of a waiver of a
Prepayment Premium (a) if such Mortgage Loan is in default or default by the
related Mortgagor is reasonably foreseeable, and such waiver would maximize
recovery of total proceeds taking into account the value of such

                                       93
<PAGE>

Prepayment Premium and the related Mortgage Loan or (b) if the prepayment is not
the result of a refinance by the Servicer or any of its affiliates and (i) such
Mortgage Loan is in default or default by the related Mortgagor is, in the
reasonable judgment of the Master Servicer or the applicable Servicer,
reasonably foreseeable, and such waiver would maximize recovery of total
proceeds taking into account the value of such Prepayment Premium and the
related Mortgage Loan or (ii) the collection of the Prepayment Premium would be
in violation of applicable laws or (iii) the collection of such Prepayment
Premium would be considered "predatory" pursuant to written guidance published
or issued by any applicable federal, state or local regulatory authority acting
in its official capacity and having jurisdiction over such matters, and (3) the
Master Servicer shall have provided or caused to be provided to the Trustee an
Opinion of Counsel (which opinion shall, if provided by the Master Servicer, be
an expense reimbursed from the Collection Account pursuant to Section 4.02(v))
in writing to the effect that such modification, waiver or amendment would not
cause an Adverse REMIC Event; provided, in no event shall an Opinion of Counsel
be required for the waiver of a Prepayment Premium under clause (2) above.

         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 (to the extent permitted by the applicable Servicing
Agreement) and shall not be an obligation of the Trust, the Trustee or the
Master Servicer.

         (b) The Master Servicer shall not be required to (i) take any action
with respect to the servicing of any Mortgage Loan that the related Servicer is
not required to take under the related Servicing Agreement and (ii) cause a
Servicer to take any action or refrain from taking any action if the related
Servicing Agreement does not require the Servicer to take such action or refrain
from taking such action; in both cases notwithstanding any provision of this
Agreement that requires the Master Servicer to take such action or cause the
Servicer to take such action.

         (c) 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

                                       94
<PAGE>

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, (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
or (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

                                       95
<PAGE>

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, the Master Servicer, 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), after a period not to exceed ninety days after the issuance of any
notice of termination pursuant to Section 6.14 or Section 9.28, as applicable,
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

                                       96
<PAGE>

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 or at the expense of the
Trust Fund, 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 and 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 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

                                       97
<PAGE>

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

                                       98
<PAGE>

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 each 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 and shall be authorized to remit
such funds to the Trustee in accordance with this 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

                                       99
<PAGE>

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, 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;

                                       100
<PAGE>

                  (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)(i) through (vi) 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

                                       101
<PAGE>

Sections 2.03(a)(i) through (vi). 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)(i) through (vi).

         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)(i)
through (vi) 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,

                                       102
<PAGE>

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, 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, 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 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

                                       104
<PAGE>

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 (without limitation of any
other right of reimbursement that the Master Servicer or any Servicer shall have
hereunder) 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.

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.

         (c) All information, reports and statements prepared by the Master
Servicer under this Agreement shall be based on information supplied to the
Master Servicer by the Servicers without independent verification thereof and
the Master Servicer shall be entitled to rely on such information.

         Section 9.25.  Annual Officer's Certificate as to Compliance.

Agencies on or before five Business Days after March 15 of each year, commencing
in March 2005, an Officer's Certificate, certifying that with respect to the
period ending on the immediately preceding December 31; (i) such Servicing

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

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

                                       106

         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 the last day of February of each year, commencing on
February 28, 2005, 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.

         To the extent that the Master Servicer receives an Annual Independent
Accountants' Servicing Report from any Servicer, the Master Servicer shall
forward a copy of such report to the Trustee. If the report is not received from
the Servicer, the Trustee may request that the Master Servicer contact the
applicable Servicer to obtain such report. The Master Servicer will not be
liable for the failure of a Servicer to provide such report.

         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.
                        ------------------------------

                                       107
<PAGE>

         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. In the event such
determination of ineligibility of the Master Servicer to continue in the
capacity of master servicer is made by the Master Servicer, no such resignation
shall become effective until a period of time not to exceed ninety days after
the Trustee receives written notice thereof from the Master Servicer and 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.
------

         (a) The Master Servicer undertakes to perform such duties and only such
duties as are specifically set forth in this Agreement.

         (b) No provision of this Agreement shall be construed to relieve the
Master Servicer from liability for its own negligent action, its own negligent
failure to act or its own willful misconduct; provided, however, that the duties
and obligations of the Master Servicer shall be determined solely by the express
provisions of this Agreement, the Master Servicer shall not be liable except for
the performance of such duties and obligations as are specifically set forth in
this Agreement; no implied covenants or obligations shall be read into this
Agreement against the Master Servicer and, in absence of bad faith on the part
of the Master Servicer, the Master Servicer may conclusively rely, as to the
truth of the statements and the correctness of the

                                       108
<PAGE>

opinions expressed therein, upon any certificates or opinions furnished to the
Master Servicer and conforming to the requirements of this Agreement.

         (c) 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.
Notwithstanding anything herein to the contrary, the Master Servicer shall have
no liability for the servicing of the Additional Collateral, including, without
limitation, the perfection, continuation, partial release, release, termination,
realization upon, substitution, foreclosure, sale, or any other matter with
respect to the Additional Collateral, or the enforcement of the Additional
Collateral Servicing Agreement.

         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 and 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

                                       109
<PAGE>

promptly pay, discharge and satisfy any judgment or decree which may be entered
against it or them in respect of such claim.

         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
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 of the Lower Tier REMIC Regular Interests is hereby designated
as a regular interest in the Lower Tier REMIC. Each Certificate, other than the
Class R Certificate and the Class A-IO2 Certificates, is hereby designated as a
regular interest in the Upper Tier REMIC. Each of the Class A-IO2 Components 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 UT-R Interest is hereby designated as the sole residual interest in
the Upper Tier REMIC. The Class R Certificate evidences ownership of the Class
LT-R Interest and the Class UT-R Interest.

         (b) The Closing Date is hereby designated as the "Startup Day" of each
REMIC within the meaning of section 860G(a)(9) of the Code. The "latest possible
maturity date" of each regular interest in each REMIC for purposes of Treasury
Regulation 1.860G-1(a)(4) is 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 to the extent provided in clause (i) above from the Certificate
Account, but only to the extent such expenses are "unanticipated expenses" for
purposes of Treasury Regulation Section 1.860G-1(b)(3)(ii).

         (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

                                       110
<PAGE>

organizations and the Trustee will be reimbursed by the Trust for all expenses
incurred therewith.

         (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.

         (f) The Trustee, the Master Servicer and the Holders of Certificates
shall take any action or cause each 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 any 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 any REMIC as
a REMIC or (ii) result in the imposition of a tax upon any REMIC (including but
not limited to the tax on prohibited transactions as defined in Code Section
860F(a)(2) and the tax on prohibited contributions set 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 any REMIC or the assets
therein, or causing any 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 any REMIC, and no such
Person shall take any such action or cause any 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 any 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 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.

                                       111
<PAGE>

         (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 any 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 or
Components, other than the Residual Certificates and Component 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

                                       112
<PAGE>

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 any 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, a 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 11.01. Binding Nature of Agreement; Assignment.
                        ---------------------------------------

         This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and permitted assigns.

         Section 11.02. Entire Agreement.
                        ----------------

                                       113
<PAGE>

         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, 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 any REMIC as a
REMIC or cause a tax to be imposed on any 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.

                                       114
<PAGE>

         (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 make available 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 to the extent such document is in the possession of the
Trustee. 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 make available to the
Depositor a copy of the report delivered to Certificateholders pursuant to
Section 4.03.

         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 (i) 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 (other than a transfer of
servicing rights between Lehman Brothers Holdings) 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

                                       118
<PAGE>

         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.

         of the Residual Certificate in order to permit the transferor to assess
         the financial capability of the Purchaser to pay such taxes.

7.       That the Purchaser will not transfer a Residual Certificate to any
         person or entity (i) as to which the Purchaser has actual knowledge

         future Treasury regulations); (iv) an estate whose income is includible
         in gross income for United States income tax purposes regardless of its
         source; (v) a trust, if a court within the United States is able to

         August 20, 1996 that are treated as United States persons prior to such
         date and elect to continue to be treated as United States persons.

10.      That the Purchaser agrees to such amendments of the Trust Agreement as
         may be required to further effectuate the restrictions on transfer of
         any Residual Certificate to such a "disqualified organization," an
         agent thereof, a Book-Entry Nominee, or a person that does not satisfy
         the requirements of paragraph 6 and paragraph 9 hereof.

11.      That the Purchaser consents to the designation of the Trustee as its
         agent to act as "tax matters person" of the Trust Fund pursuant to the

         _______________________ (the "Transferor") has reviewed the attached
affidavit of _____________________________ (the "Transferee"), and has no actual

believe that the Transferee has the intention to impede the assessment or
collection of any federal, state or local taxes legally required to be paid with
respect to a Residual Certificate. In addition, the Transferor has conducted a
reasonable investigation at the time of the transfer and found that the
Transferee had historically paid its debts as they came due and found no
significant evidence to indicate that the Transferee will not continue to pay
its debts as they become due.

Dear Sirs:

         In connection with our proposed purchase of $______________ principal
amount of Structured Asset Securities Corporation Mortgage Pass-Through
Certificates, Series 2004-5H (the "Privately Offered Certificates") of
Structured Asset Securities Corporation (the "Depositor") which are held in the
form of Definitive Certificates, 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
         (the "Trust Agreement"), dated as of January 1, 2004 among Structured
         Asset Securities Corporation, as Depositor, Aurora Loan Services Inc.,
         as Master Servicer and Citibank, N.A., as 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.

                                       G-1

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 investment in the
         Privately Offered Certificates, and we and any account for which we are
         acting are each able to bear the economic risk of such investment.

4.       We are an Institutional Accredited Investor and we are acquiring the
         Privately Offered Certificates purchased by us for our own account or
         for one or more accounts (each of which is an Institutional Accredited
         Investor) as to each of which we exercise sole investment discretion.

5.       We have received such information as we deem necessary in order to make
         our investment decision.

6.       If we are acquiring ERISA-Restricted Certificates, we understand that
         in accordance with ERISA, the Code, Similar Law and the Underwriter's
         Exemption, no Plan and no person acting on behalf of such a Plan may
         acquire such Certificate except in accordance with Section 3.03(d) of
         the Trust Agreement.

         Terms used in this letter which are not otherwise defined herein have
the respective meanings assigned thereto in the Trust Agreement.

Installment Closings), in cash by wire transfer of immediately available funds
(denominated in U.S. dollars) to the Company's account (with respect to each

from the Company in such Installment Closing.

         (c) Upon execution and delivery of this Agreement, as collateral for
the obligation of Investor to consummate the Installment Closings hereunder, the
Investor shall deliver to the Company a letter of credit, in form and substance
reasonably acceptable to the Company (the "LETTER OF CREDIT"), along with any
authorizations deemed necessary or advisable by the Company to allow the Company
to draw down on the Letter of Credit in accordance with the terms and conditions
of this Agreement. In the event of a failure by the Investor to pay the
aggregate Purchase Price with respect to one or more Installment Closings, the
Company may (but is not required to) draw down upon the Letter of Credit in an
amount equal to the aggregate Purchase Price with respect to such Installment
Closing.

         (d) The Investor's obligation to consummate each Installment Closing
shall be conditioned upon: (i) receipt by the Investor of evidence that a stock
certificate representing the shares of Common Stock purchased by the Investor
from the Company at such Installment Closing has been issued to the Investor;
(ii) all of the representations and warranties of the Company set forth in this
Agreement being true and correct as of the applicable Installment Closing Date;
and (iii) the Company not being in material breach of this Agreement as of the
applicable Installment Closing Dat/e. The Company's obligation to consummate

Agreement being true and correct as of the applicable Installment Closing Date;
and (iii) the Investor not being in material breach of this Agreement as of the
applicable Installment Closing Date.

                  (ii) materially conflict with or result in any material breach

         SECTION 3. REPRESENTATIONS AND WARRANTIES OF THE INVESTOR TO THE
COMPANY.

         The Investor represents and warrants to the Company, as of the date of
this Agreement and as of each Installment Closing Date, as follows:

         (a) The execution, delivery and performance by the Investor of this
Agreement and issuance of the Purchased Shares have been duly authorized by all
requisite action on the part of the Investor. This Agreement has been duly
executed and delivered by the Investor and constitutes a valid and binding
obligation of the Investor, enforceable in accordance with its respective terms.
The execution, delivery and performance of this Agreement, and the compliance
with the provisions hereof and thereof by the Investor, will not:

                  (i) materially violate any provision of law, statute,
         ordinance, rule or regulation or any ruling, writ, injunction, order,
         judgment or decree of any court, administrative agency or other
         governmental body;

                  (ii) materially conflict with or result in any material breach
         of any of the terms, conditions or provisions of, or constitute (with
         due notice or lapse of time, or both) a material default (or give rise
         to any right of termination, cancellation or acceleration) under any
         agreement, document, instrument, contract, understanding, arrangement,
         note, indenture, mortgage or lease to which the Investor is a party or
         under which the Investor or any of its assets are bound or affected or
         conflict with any organizational or other governing document of the
         Investor; or

                  (iii) result in the creation of any lien, security interest,
         charge or encumbrance upon any of the properties or assets of the
         Investor.

         (b) The Investor understands and acknowledges that the offering and
sale of the Purchased Shares pursuant to this Agreement is intended to be exempt
from registration under the Securities Act, and from qualification under any
applicable state securities law by virtue of Section 4(2) of the Securities Act
and Rule 506 of Regulation D thereunder, on the ground, among others, that no
distribution or public offering of Purchased Shares is to be effected and the
Purchased Shares will be issued by the Company in connection with a transaction
that does not involve any public offering within the meaning of Section 4(2) of
the Securities Act, the rules and regulations of the United States Securities
and Exchange Commission thereunder, or any comparable provision of applicable
securities laws or the rules and regulations of the regulatory authorities
thereunder.

         (c) The Investor will acquire the Purchased Shares for investment for
the account of the Investor and not for the account of any other person or
entity of any kind, and not with a view toward resale or other distribution
thereof. The Investor understands that the Purchased Shares have not been
registered under the Securities Act and applicable United States state
securities laws and, therefore, cannot be resold unless they are subsequently
registered under the Securities Act and applicable United States state
securities laws or unless an exemption from such registration is available.
Investor is acquiring the Purchased Shares hereunder in the ordinary course of
its business. Investor does not have any agreement or understanding, directly or
indirectly, with any person or entity of any kind to distribute any of the
Purchased Shares. The Investor further understands and agrees that, until so
registered or transferred pursuant to the provisions of Rule 144 under the
Securities Act, the certificate(s) for the Purchased Shares shall bear a legend,
prominently stamped or printed thereon, reading substantially as follows:

         THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933, AS AMENDED (THE "SECURITIES ACT"), OR APPLICABLE STATE SECURITIES
         LAWS. THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A
         VIEW TO THEIR DISTRIBUTION OR RESALE, AND MAY NOT BE SOLD, PLEDGED, OR
         OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT FOR
         SUCH SECURITIES UNDER THE SECURITIES ACT AND APPLICABLE STATE
         SECURITIES LAWS, OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY
         TO THE EFFECT THAT SUCH REGISTRATION IS NOT REQUIRED.

                                       3-
<PAGE>

         (d) The Investor, during the course of this transaction and prior to
the purchase of the Purchased Shares, has had the opportunity to ask questions
of and receive answers from representatives of the Company concerning the terms
and conditions of the offering, and to obtain any additional information or
documents relative to the Company, its business and an investment, as the
Investor has deemed necessary. The Investor agrees and acknowledges, however,
that it has not been furnished any offering literature or prospectus concerning
the Company other than this Agreement and, in making its decision to acquire the
Purchased Shares hereunder, the Investor has relied solely upon this Agreement
and independent investigations made by the Investor. The Investor acknowledges
that no representations or warranties have been made to the Investor by the
Company, or any officer, employee, agent or affiliate of the Company, except as
contained in this Agreement.

         (e) The Investor understands that the offering of Purchased Shares
pursuant to this Agreement is limited solely to "accredited investors," as that
term is defined in Regulation D under the Securities Act. The Investor
represents and warrants to the Company that the Investor is an "accredited
investor", as so defined, by virtue of the Investor meeting the criteria checked
by the Investor on the signature page hereto, and that the Investor's principal
place of business is as listed on the signature page hereto.

         (f) The Investor has the capacity to protect its own interests in
connection with the purchase of the Purchased Shares. The purchase of the
Purchased Shares by the Investor is consistent with its general investment
objectives and the Investor understands that the purchase of the Purchased
Shares is a speculative investment that involves a high degree of risk. The
Investor can bear the economic risks of this investment and can afford a
complete loss of its investment in the Purchased Shares. The Investor
understands that there is no established market for the Company's capital stock
(including, without limitation, Common Stock) and there is no assurance that any
public market for such stock will develop. The Investor has no present need for
liquidity in connection with its purchase of the Purchased Shares.

         (g) The Investor understands and acknowledges that the Purchased Shares
are "restricted securities" under United States securities laws and any
purported transfer of the Purchased Shares in violation of applicable law is
null and void. The Investor understands and acknowledges that the Company may,
at its discretion, refuse to register on its share transfer books any purported
transferee of the Purchased Shares in the event of an attempted transfer thereof
in violation of applicable law.

         (h) If the Investor is a nonresident alien individual, corporation,
partnership, limited liability company, trust, estate or other entity, it is not
a U.S. person (as those terms are defined in the Internal Revenue Code of 1986,
as amended (the "INTERNAL REVENUE CODE"), and the United States Treasury
Regulations promulgated thereunder), and it acknowledges that the Company is
required, as a withholding agent, to withhold U.S. taxes and/or backup
withholding with respect to dividends and other distributions paid with respect
to the Purchased Shares in accordance with the applicable provisions of the
Internal Revenue Code and Treasury Regulations, unless (x) an exemption from
such withholding is available, (y) the Investor provides to the Company in a
timely manner duly completed documentation evidencing qualification for such
exemption, and (z) the Company determines, in its sole discretion, that the
Company may rely on such documentation for this purpose. The Investor has
provided to the Company a duly completed Internal Revenue Service ("IRS") Form
W-8BEN (Certificate of Foreign Status of Beneficial Owner for United States Tax
Withholding) and agrees to provide to the Company, in a timely manner, such
other duly completed documentation as the Company may request (including any
applicable alternative IRS Forms if Form W-8BEN is inapplicable to the Investor
and such duly completed updated IRS forms and other documentation as the Company
may request from time to time), all of which documentation must be in form and
substance satisfactory to the Company;

                                      -4-
<PAGE>

         SECTION 4. INDEMNIFICATION. The Investor agrees to indemnify and hold
harmless the Company and its affiliates, agents, representatives, employees,
directors, officers and stockholders from and against any and all loss,
liability, claim, damage and expense whatsoever (including, but not limited to,
any and all expenses reasonably incurred in investigating, preparing or
defending against any litigation commenced or threatened or any claim
whatsoever) arising out of or based upon: (a) any false representation and
warranty of the Investor contained in this Agreement or any breach or failure by
the Investor to comply with any covenant and/or agreement made by the Investor
herein; or (b) any transfer of the Purchased Shares contrary to such
representations and warranties or covenants and agreements.

         SECTION 5. TERMINATION. Either party may terminate this Agreement upon
material breach of this Agreement by the other party that has not been cured in
its entirety within fifteen (15) business days after written notice thereof has
been provided to the breaching party. The parties agree that a party's failure
to consummate the Installment Closings in accordance with the terms and
conditions of this Agreement constitute a material breach by such party of this
Agreement.

         SECTION 6.  GENERAL PROVISIONS.

         (a) REMEDIES. In case any one or more of the covenants and/or
agreements set forth in this Agreement shall have been breached by any party
hereto, the party entitled to the benefit of such covenants or agreements may
proceed to protect and enforce their rights either by suit in equity and/or
action at law, including, but not limited to, an action for damages as a result
of any such breach and/or an action for specific performance of any such
covenant or agreement contained in this Agreement. The rights, powers and
remedies of the parties under this Agreement are cumulative and not exclusive of
any other right, power or remedy which such parties may have under any other
agreement or law. No single or partial assertion or exercise of any right, power
or remedy of a party hereunder shall preclude any other or further assertion or
exercise thereof.

         (b) SUCCESSORS AND ASSIGNS. Except as otherwise expressly provided
herein, this Agreement shall bind and inure to the benefit of the Company and
the Investor and their respective permitted successors and assigns. This
Agreement may not be assigned by either party without the prior written consent
of the other party.

         (c) ENTIRE AGREEMENT. This Agreement (including any schedules and
exhibits hereto) contains the entire agreement among the parties with respect to
the subject matter hereof and supersedes all prior and contemporaneous
arrangements or understandings, whether written or oral, with respect thereto.

         (d) CHANGES. The terms and provisions of this Agreement may not be
modified or amended, or any of the provisions hereof waived, temporarily or
permanently, except pursuant to a writing executed by duly authorized
representatives of the Company and the Investor.

         (e) COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by the different parties on separate counterparts each of
which, when so executed and delivered, shall be an original but all of which
together shall constitute one and the same instrument.

         (f) SEVERABILITY. Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

         (g) GOVERNING LAW; VENUE; JURISDICTION. The corporate law of the State
of Nevada will govern all questions concerning the relative rights of the
Company and the holders of its securities (including, without limitation, the
Purchased Shares). All other questions concerning the construction, validity and
interpretation of this Agreement will be governed by and construed in accordance
with the internal laws of the State of Maryland, without giving effect to any
choice of law or conflict of law provision or rule (whether of the State of

                                      -5-
<PAGE>

Maryland or any other jurisdiction) that would cause the application of the laws
of any jurisdiction other than the State of Maryland. The parties each agree
that venue for any dispute arising under this Agreement shall be proper in any
state court located in Montgomery County in the State of Maryland or in the
United States District Court for the District of Maryland (if a basis for
federal jurisdiction exists) and each party hereby irrevocably waives any right
to object to the maintenance of a suit in such courts on the basis of improper
venue or of inconvenience of forum. Each party irrevocably consents to the
non-exclusive jurisdiction of any state court located in Montgomery County in
the State of Maryland or in the United States District Court for the District of
Maryland (if a basis for federal jurisdiction exists).

         (h) WAIVER OF JURY TRIAL. The parties to this Agreement each hereby
irrevocably waives, to the fullest extent permitted by law, any right to trial
by jury of any claim, demand, action or cause of action arising under this
Agreement, whether now existing or hereafter arising, and whether in contract,
tort, equity, or otherwise. The parties to this Agreement each hereby
irrevocably agrees and consents that any such claim, demand, action or cause of
action shall be decided by court trial without a jury and that the parties to
this Agreement may file an original counterpart of a copy of this Agreement with
any court as written evidence of the consent of the parties hereto to the waiver
of their right to trial by jury.

         (i) NOTICES. Any and all notices or other communications or deliveries
required or permitted to be provided hereunder shall be in writing and shall be
deemed given and effective on the earliest of (i) the date of transmission, if
such notice or communication is delivered via facsimile at the facsimile number
