         This TRUST AGREEMENT, dated as of March 1, 2003 (the "Agreement"), by
and among MERRILL LYNCH MORTGAGE INVESTORS, INC., a Delaware corporation, as
depositor (the "Depositor"), and WELLS FARGO BANK MINNESOTA, NATIONAL
ASSOCIATION, as Trustee (the "Trustee"), and acknowledged by MERRILL LYNCH
CREDIT CORPORATION a Delaware corporation, as seller (the "Seller"), for
purposes of Section 2.04.

                              PRELIMINARY STATEMENT

         The Depositor has acquired the Mortgage Loans from the Seller and at
the Closing Date is the owner of the Mortgage Loans and the other property being
conveyed by the Depositor to the Trustee hereunder for inclusion in the Trust
Fund. On the Closing Date, the Depositor will acquire the Certificates from the
Trustee as consideration for the Depositor's 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 Seller in
the Mortgage Loan Purchase and Sale Agreement and in this Agreement and by the
Depositor 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 Trustee 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
(exclusive of the Additional Collateral and assets held in the Basis Risk
Reserve Fund) be treated for federal income tax purposes as comprising two real
estate mortgage investment conduits (each a "REMIC" or, in the alternative, the
"Lower Tier REMIC" and the "Upper Tier REMIC," respectively). The Certificates,
other than the Class A-R Certificate, shall represent ownership of regular
interests in the Upper Tier REMIC. In addition, each of the LIBOR Certificates
represents the right to receive payments in respect of Basis Risk Shortfalls and
Unpaid Basis Risk Shortfalls from the Basis Risk Reserve Fund as provided in
Section 5.06. The Basis Risk Reserve Fund is beneficially owned for federal
income tax purposes by the owners of the Interest-Only Certificates. The Class
A-R Certificate represents the sole class of residual interest in the Upper Tier
REMIC and the sole class of residual interest in the Lower Tier REMIC.

         The Upper Tier REMIC shall hold as its assets the several classes of
uncertificated Lower Tier Regular Interests in the Lower Tier REMIC. The Lower
Tier REMIC shall hold as its assets the property of the Trust Fund other than
the Lower Tier REMIC Interests, the Basis Risk Reserve Fund and the Additional
Collateral. Each Certificate, other than the Class A-R Certificate, the Class
X-B Certificates and the portion of the LIBOR Certificates representing the
right to receive payments in respect of Basis Risk Shortfalls and Unpaid Basis
Risk Shortfalls, is hereby designated as a regular interest in the Upper Tier
REMIC for purposes of the REMIC Provisions. Each Component, other than any
portion thereof deemed to represent the obligation to make payments in respect
of Basis Risk Shortfalls and Unpaid Basis Risk Shortfalls, is hereby designated
as a regular interest in the Upper Tier REMIC for purposes of the REMIC
Provisions. Each Lower Tier Regular Interest is hereby designated as a regular
interest in the Lower Tier REMIC for purposes of the REMIC Provisions. The Class
LTR Interest is hereby designated as the sole class of residual interest in the
Lower Tier REMIC for purposes of the REMIC

<PAGE>

Provisions. The Class A-R Certificate, other than the portion thereof
representing the right to receive payments in respect of Basis Risk Shortfalls
and Unpaid Basis Risk Shortfalls from the Basis Risk Reserve Fund, is hereby
designated as the sole class of residual interest in the Upper Tier REMIC for
purposes of the REMIC provisions and will also represent the Class LTR Interest.

</TABLE>

---------------
(1)  The Class LTR interest represents the sole class of residual interest in
     the Lower Tier REMIC and has neither a principal amount nor an interest
     rate. The Class LTR Interest shall be represented by the Class A-R
     Certificate.

(2)  The interest rate for the Class LT1A Interest, the Class LT2A Interest, the
     Class LTB1 Interest, the Class LTB2 Interest, the Class LTB3 Interest, the
     Class LTB4-B6 Interest and the Class LTA-R Interest for any Distribution
     Date (and the related Accrual Period) is a per annum rate equal to the Net
     WAC.

     On each Distribution Date the Trustee shall distribute interest and
principal on, and shall allocate Realized Losses among, the Lower Tier REMIC
Interests in the same manner that such amounts are distributed on and such
losses are allocated among the Corresponding Classes of Certificates and
Components. Notwithstanding the preceding sentence, (i) the first $0.16 of
losses with respect to principal on the Mortgage Loans shall be allocated to the
Class LTB4-B6 Interest and (ii) immediately preceding any payment to the Class
A-R Certificate pursuant to Section 5.02(a)(vii) or 5.02(b) attributable to
principal received with respect to any Mortgage

Loan, a payment shall be treated as made to the Class LTB4-B6 Interest in
reduction of the principal balance thereof, if any, to zero.

Prepayment Percentage unless both Step Down Conditions are satisfied; and
provided, further, that if on any such Distribution Date the Pro Rata Senior
Percentage exceeds the initial Pro Rata Senior Percentage, the Senior Prepayment
Percentage for that Distribution Date shall again equal 100%.

<PAGE>

         Notwithstanding the above, if on any Distribution Date the Two Times
Test is satisfied, the Senior Prepayment Percentage shall equal the Senior

Distribution Date shall be limited to the percentage necessary to reduce that
Class Principal Amount to zero.

                  received with respect to that Mortgage Loan; and

                  (3)      the Senior Prepayment Percentage of the amounts

Voting Interests shall be allocated among the Class X-A-1, Class X-A-2 and Class
X-B Certificates, while they remain outstanding, in proportion to their relative
Class Notional Amounts. Voting Interests shall be allocated among the
Certificates within each such Class in proportion to their Certificate Principal
Amounts or Percentage Interests.

                              DECLARATION OF TRUST;
                            ISSUANCE OF CERTIFICATES

         Section 2.01      Creation and Declaration of Trust Fund; Conveyance of
                           Mortgage Loans.

         (a) Concurrently with the execution and delivery of this Agreement, the
Depositor does hereby establish the Trust Fund and transfer, assign, set over,
deposit with and otherwise convey to the Trustee, without recourse, subject to
Sections 2.02 and 2.04, in trust, all the right, title and interest of the
Depositor in and to the Trust Fund. Such conveyance includes, without
limitation, (i) the Mortgage Loans, including the right to all payments of
principal and interest received on or with respect to the Mortgage Loans on and
after the Cut-off Date (other than Scheduled Payments due on or before such
date), and all such payments due after such date but received prior to such date
and intended by the related Mortgagors to be applied after such date; (ii) all
of the Depositor's right, title and interest in and to all amounts from time to
time credited to and the proceeds of the Distribution Account, any Custodial
Accounts or any Escrow Account established with respect to the Mortgage Loans;
(iii) all of the Depositor's rights under the Servicing Agreement as modified by
the Acknowledgements and the Mortgage Loan Purchase and Sale Agreement; (iv) all
of the Depositor's right, title or interest in REO Property and the proceeds
thereof; (v) all of the Depositor's rights under any Insurance Policies relating
to the Mortgage Loans; (vi) the Depositor's security interest in any collateral
pledged to secure the Mortgage Loans, including the Mortgaged Properties and any
Additional Collateral relating to the Additional Collateral Mortgage Loans,
including, but not limited to, any pledge, control and guaranty agreements and
the Limited Purpose Surety Bond and any proceeds of the foregoing, to have and
to hold, in trust; and the Trustee declares that, subject to the review provided
for in Section 2.02, it has received and shall hold the Trust Fund, as trustee,
in trust, for the benefit and use of the Holders of the Certificates and for the
purposes and subject to the terms and conditions set forth in this Agreement,
and, concurrently with such receipt, has caused to be executed, authenticated
and delivered to or upon the order of the Depositor, in exchange for the Trust
Fund, Certificates in the authorized denominations evidencing the entire
ownership of the Trust Fund. Notwithstanding anything to the contrary in this
Agreement, the Trust Fund shall not obtain title to or beneficial ownership of
any Additional Collateral as a result of or in lieu of the disposition thereof
or otherwise.

         The foregoing sale, transfer, assignment, set-over, deposit and
conveyance does not and is not intended to result in the 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 therein.

         In connection with such transfer and assignment of the Mortgage Loans,
the Depositor shall deliver to, and deposit with, or cause to be delivered to
and deposited with, the Trustee, the documents or instruments described in
Section 2 of the Custody Agreement with respect to each Mortgage Loan; provided
that in Section 2a thereof, a lost note affidavit (including a copy of the
original Mortgage Note) may be delivered in lieu of the original Mortgage Note
(each a "Trustee Mortgage File") (the Custody Agreement to be deemed modified by
the foregoing) so transferred and assigned.

<PAGE>

         (b) The Depositor shall cause the Mortgage Notes with respect to each
Mortgage Loan to be completed either (A) in blank, without recourse, or (B)
endorsed to "Wells Fargo Bank Minnesota, National Association, as Trustee of the
Merrill Lynch Mortgage Investors Trust Series MLCC 2003-B, Mortgage Pass-Through
Certificates, without recourse" and the Depositor shall cause Assignments of
Mortgage with respect to each Mortgage Loan other than a Cooperative Mortgage
Loan to be completed either (A) in blank or (B) to "Wells Fargo Bank Minnesota,
National Association, as Trustee of the Merrill Lynch Mortgage Investors Trust
Series MLCC 2003-B, Mortgage Pass-Through Certificates," within 30 days of the
Closing Date for purpose of their recording; provided, however, that such
Assignments need not be recorded unless required in writing by the Rating
Agencies.

         (c) In instances where a title insurance policy is required to be
delivered to the Trustee and is not so delivered, the Depositor will provide a
copy of such title insurance policy to the Trustee, as promptly as practicable
after the execution and delivery hereof, but in any case within 270 days of the
Closing Date.

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

         Section 2.02      Acceptance of Trust Fund by Trustee; Review of
                           Documentation for Trust Fund.

         (a) The Trustee, by execution and delivery hereof, acknowledges receipt
by it of the Trustee Mortgage Files pertaining to the Mortgage Loans listed on
the Mortgage Loan Schedule, subject to review thereof as provided herein. Upon
receipt by the Trustee of each Trustee Mortgage File, the Trustee shall review
each Trustee Mortgage File in accordance with the review procedures set forth in
Section 2 of Amendment No. 1 to the Custody Agreement.

         In making such verifications, the Trustee may rely conclusively on the
Mortgage Loan Schedule and the documents constituting the Trustee Mortgage File,
and the Trustee shall have no obligation to independently verify the validity,
enforceability, recordability, sufficiency, due authorization or genuineness of
any document in any Trustee Mortgage File or any Mortgage Loan hereunder, nor
the collectibility, insurability, effectiveness or suitability of any Mortgage
Loan hereunder. The Trustee shall prepare an initial certification to be
delivered to the Depositor and the Servicer on the Closing Date in the form
annexed hereto as Exhibit K (the "Initial Certification") with respect to the
Mortgage Loans (other than any Mortgage Loan paid in full or any Mortgage Loan
specifically identified on the Schedule of Exceptions attached to the Initial
Certification (the "Schedule of Exceptions") as not covered by such Initial
Certification) listed on the Mortgage Loan Schedule. If the Trustee determines
from such verification that any discrepancy or deficiency exists with respect to
a Trustee Mortgage File, the Trustee shall note such omission, discrepancy or
deficiency on the Schedule of Exceptions attached to the Initial Certification,
and shall deliver a copy (which shall be electronic, if requested) of the
Schedule of

<PAGE>

Exceptions to the Depositor on the Closing Date. During the life of the Mortgage
Loans (while subject to this Agreement), in the event the Trustee discovers any
defect with respect to any Trustee Mortgage File, the Trustee shall give written
specification of such defect to the Depositor. Except as specifically provided
above, the Trustee shall be under no duty to review, inspect or examine such
documents to determine that any of them are enforceable or appropriate for their
prescribed purpose.

         (b) If in the course of the review described in paragraph (a) of this
Section 2.02 the Trustee discovers any document or documents constituting a part
of a Trustee 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, upon discovering such
Material Defect shall promptly identify the Mortgage Loan to which such Material
Defect relates to the Depositor and the Servicer. Within 90 days of its receipt
of such notice (but in no case prior to the 270th day following the Closing
Date), 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 Servicer
notifies the Depositor and the Trustee in writing that (i) a loss has occurred
and (ii) such loss relates to a Mortgage Loan for which the Trustee previously
identified a Material Defect or for which the Servicer has identified a Material
Defect and the Depositor has not cured such Material Defect, then the Depositor
shall repurchase such Mortgage Loan at the Purchase Price therefore in the event
that such loss would, if such Mortgage Loan is not repurchased by the Depositor,
constitute a Realized Loss and such loss is attributable to the failure of the
Depositor to have cured such Material Defect. 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 Trustee each acting
in good faith, absent such Material Defect, such loss would not have been
incurred. Within the two-year period following the Closing Date, the Depositor
may, in lieu of repurchasing a Mortgage Loan pursuant to this Section 2.02(b),
substitute for such Mortgage Loan a Replacement Mortgage Loan subject to the
provisions of Section 2.04.

         (c) Within 270 days following the Closing Date, the Trustee shall
deliver to the Depositor and the Servicer, a final certification substantially
in the form attached as Exhibit L (the "Final Certification") evidencing the
completeness of the Trustee Mortgage Files in its possession or control, with
any exceptions noted on the Scheduled of Exceptions attached to the Final
Certification.

         (d) 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.

         (e) Upon execution of this Agreement, the Depositor hereby delivers to
the Trustee and the Trustee acknowledges receipt of the Servicing Agreement and
the Mortgage Loan Purchase and Sale Agreement.

<PAGE>

         Section 2.03      Representations and Warranties of the Depositor.

         The Depositor hereby represents and warrants to the Trustee, for the
benefit of the Certificateholders 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
         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, 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;

                  (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)

<PAGE>

         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;

                  (vii)    This Agreement creates a valid and continuing
         security interest (as defined in the applicable Uniform Commercial Code
         (the "UCC"), in the Mortgage Loans in favor of the Trustee, which
         security interest is prior to all other liens, and is enforceable as
         such against creditors of and purchasers from the Depositor;

                  (viii)   The Mortgage Loans constitute "instruments" within
         the meaning of the applicable UCC;

                  (ix)     Other than the security interest granted to the
         Trustee pursuant to this Agreement, the Depositor has not pledged,
         assigned, sold, granted a security interest in, or otherwise conveyed
         any of the Mortgage Loans. The Depositor has not authorized the filing
         of and is not aware of any financing statement against the Depositor
         that includes a description of the collateral covering the Mortgage
         Loans other than a financing statement relating to the security
         interest granted to the Trustee hereunder or that has been terminated.
         The Depositor is not aware of any judgment or tax lien filings against
         the Depositor;

                  (x)      None of the Mortgage Loans have any marks or
         notations indicating that such Mortgage Loans have been pledged,
         assigned or otherwise conveyed to any Person other than the Trustee;
         and

                  (xi)     The Depositor has received all consents and approvals
         required by the terms of the Mortgage Loans to convey the Mortgage
         Loans hereunder to the Trustee;

                  (xii)    Each Mortgage Loan is a "qualified mortgage" within
         the meaning of Section 860G(a)(3) of the Code (without regard to
         Treasury Regulations Section 1.860G-2(f)) or any similar rule that
         provides that a defective obligation is a qualified mortgage for a
         temporary period;

                  (xiii)   No Mortgage Loan provides for interest other than at
         either (x) a single fixed rate in effect throughout the term of the
         Mortgage Loan or (y) a single "variable rate" (within the meaning of
         Treasury Regulations Section 1.860G-1(a)(3)) in effect throughout the
         term of the Mortgage Loan;

<PAGE>

                  (xiv)    No Mortgage is the subject of pending or final
         foreclosure proceedings; and

                  (xv)     As of the Closing Date, the Depositor would not
         initiate foreclosure proceedings with respect to any Mortgage Loan
         based on such Mortgage Loan's delinquency status prior to the next
         scheduled payment date for such Mortgage Loan.

         The foregoing representations made in this Section 2.03 shall survive
the termination of this Agreement and shall not be waived by any party hereto.

          Section 2.04      Discovery of Breach; Repurchase or Substitution of
                            Mortgage Loans.

         (a) Pursuant to Sections 3(a) and 3(b) of the Mortgage Loan Purchase
and Sale Agreement, the Seller has made certain representations and warranties
as to the characteristics of the Mortgage Loans (set forth in Schedule B of this
Agreement) as of the Closing Date and the conveyance thereof from the Seller to
the Depositor, for the benefit of the Trustee and the Certificateholders, and
the Seller has agreed to comply with the provisions of this Section 2.04 in
respect of a breach of any of such representations and warranties.

         It is understood and agreed that (i) the representations and warranties
of the Depositor set forth in Section 2.03 and (ii) the representations and
warranties of the Seller set forth in Sections 3(a) and 3(b) of the Mortgage
Loan Purchase and Sale Agreement shall survive delivery of the Trustee 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 (i) by the
Depositor, the Seller or the Trustee of a breach of any representation or
warranty made by Depositor under Section 2.03 which materially adversely affects
the value of a Mortgage Loan or the interest therein of the Certificateholder (a
"Defective Mortgage Loan") or (ii) by the Depositor or the Seller of the breach
by the Seller of any representation or warranty under the Mortgage Loan Purchase
and Sale Agreement in respect of any Mortgage Loan, which breach results in the
Mortgage Loan being a "Defective Mortgage Loan" (each of such parties hereby
agreeing to give written notice of such breach to the Trustee and the other of
such parties), the Trustee, or its designee, shall promptly notify the Depositor
in writing of such breach and request that the Depositor cure or cause the cure
of such breach within 90 days from the date that the Depositor discovered or was
notified of such breach, and if the Depositor does not cure such breach in all
material respects during such period, the Trustee shall (i) in the case of an
uncured breach under Section 2.03, cause the Depositor to repurchase such
Defective Mortgage Loan at the Purchase Price and (ii) in the case of an uncured
breach by the Seller under the Mortgage Loan Purchase and Sale Agreement, cause
the Depositor to enforce the Seller's obligation under the Mortgage Loan
Purchase and Sale Agreement and cause the Seller to repurchase that Defective
Mortgage Loan from the Trust Fund at the Purchase Price, in each case on or
prior to the Determination Date following the expiration of such 90-day period
(subject to Section 2.04(b) below); provided, however, that, in connection with
any such breach under clause (ii) above that could not reasonably have been
cured within such 90-day period, if the Seller shall have commenced to cure such
breach within such 90-day period, the Seller shall be permitted to proceed
thereafter diligently and expeditiously to cure the same within an additional
90-day period. The Purchase Price for the repurchased Defective Mortgage Loan
shall be deposited in the related Distribution Account, and the Trustee, or its
designee, upon receipt of such deposit and two copies of a

<PAGE>

Request for Release with respect to such Defective Mortgage Loan, shall release
to the Seller, the related Trustee Mortgage File and shall execute and deliver
such instruments of transfer or assignment, in each case without recourse,
representation or warranties, as either party shall furnish to it and as shall
be necessary to vest in such party any Defective Mortgage Loan released pursuant
hereto and the Trustee, or its designee, shall have no further responsibility
with regard to such Trustee Mortgage File (it being understood that the Trustee
shall have no responsibility for determining the sufficiency of such assignment
for its intended purpose). In lieu of repurchasing any such Defective Mortgage
Loan as provided above, the Seller may cause such Defective Mortgage Loan to be
removed from the Trust Fund (in which case it shall become a Deleted Mortgage
Loan) and substitute one or more Replacement Mortgage Loans in the manner and
subject to the limitations set forth in Section 2.04(b) below. It is understood
and agreed that the obligation of the Seller to cure or to repurchase (or to
substitute for) any Mortgage Loan as to which a breach has occurred and is
continuing shall constitute the sole remedy against the Seller respecting such
breach available to the Trustee on behalf of the Certificateholders. With
respect to the representations and warranties described in Schedule B which are
made to the best of the Seller's knowledge, if it is discovered by any of the
Depositor, the Seller or the Trustee that the substance of such representation
and warranty is inaccurate and such inaccuracy materially and adversely affects
the value of the relate Mortgage Loan, then notwithstanding the Seller's lack of
knowledge with respect to the substance of such representation and warranty,
such inaccuracy shall be deemed a breach of the applicable representation or
warranty.

         (b) Any substitution of Replacement Mortgage Loans for Deleted Mortgage
Loans made pursuant to Section 2.04(a) above must be effected prior to the last
Business Day that is within two years after the Closing Date. As to any Deleted
Mortgage Loan for which the Seller substitutes a Replacement Mortgage Loan or
Loans, such substitution shall be effected by delivering to the Trustee for such
Replacement Mortgage Loan or Loans, the Mortgage Note, the Mortgage, the
Assignment to the Trustee, and such other documents and agreements, with all
necessary endorsements thereon, together with an Officers' Certificate stating
that each such Replacement Mortgage Loan satisfies the definition thereof and
specifying the Substitution Amount (as described below), if any, in connection
with such substitution. The Trustee shall acknowledge receipt for such
Replacement Mortgage Loan and, within 45 days thereafter, shall review such
Mortgage Documents as specified in this Agreement under Section 2.02(a) and
deliver to the Depositor, with respect to such Replacement Mortgage Loans, a
certification substantially in the form of a revised Initial Certification, with
any exceptions noted thereon. Within one year of the date of substitution, the
Trustee shall deliver to the Depositor a certification substantially in the form
of a revised Final Certification, with respect to such Replacement Mortgage
Loans, with any exceptions noted thereon. Monthly Payments due with respect to
Replacement Mortgage Loans in the month of substitution shall not be included as
part of the Trust Fund and shall be retained by the Seller. For the month of
substitution, distributions to Certificateholders shall reflect the collections
and recoveries in respect of such Deleted Mortgage in the Due Period preceding
the month of substitution and the Seller shall thereafter be entitled to retain
all amounts subsequently received in respect of such Deleted Mortgage Loan. Upon
such substitution, such Replacement Mortgage Loan shall constitute part of the
Trust Fund and shall be subject in all respects to the terms of this Agreement
and the Mortgage Loan Purchase and Sale Agreement, including all representations
and warranties thereof included in the Mortgage Loan Purchase and Sale
Agreement, in each case as of the date of substitution.

<PAGE>


         For any month in which the Seller substitutes one or more Replacement
Mortgage Loans for one or more Deleted Mortgage Loans, the Trustee, based upon
information provided by the Servicer, shall determine the excess (each, a
"Substitution Amount"), if any, by which the aggregate Purchase Price of all
such Deleted Mortgage Loans exceeds the aggregate Stated Principal Balance of
the Replacement Mortgage Loans replacing such Deleted Mortgage Loans, together
with one month's interest on such excess amount at the applicable Net Mortgage
Rate. On the date of such substitution, the Seller shall deliver or cause to be
delivered to the Servicer for deposit in the Custodial Account an amount equal
to the related Substitution Amount, if any, and the Trustee, upon receipt of the
related Replacement Mortgage Loan or Loans and two copies of a Request for
Release with respect to the Deleted Mortgage Loan or Loans, shall release to the
Seller the related Trustee Mortgage File or Files and shall execute and deliver
such instruments of transfer or assignment, in each case without recourse, as
the Seller shall deliver to it and as shall be necessary to vest therein any
Deleted Mortgage Loan released pursuant hereto.

         In addition, the Seller shall obtain at its own expense and deliver to
the Trustee an Opinion of Counsel to the effect that such substitution (either
specifically or as a class of transactions) shall not cause (a) any federal tax
to be imposed on the Trust Fund, including without limitation, any federal tax
imposed on "prohibited transactions" under Section 860F(a)(l) of the Code or on
"contributions after the startup date" under Section 860G(d)(l) of the Code, or
(b) any REMIC created hereunder to fail to qualify as a REMIC at any time that
any Certificate is outstanding. If such Opinion of Counsel can not be delivered,
then such substitution may only be effected at such time as the required Opinion
of Counsel can be given.

         (c) Upon discovery by the Seller, the Depositor or the Trustee that any
Mortgage Loan does not constitute a "qualified mortgage" within the meaning of
Section 860G(a)(3) of the Code, the party discovering such fact shall within two
Business Days give written notice thereof to the other parties. In connection
therewith, the Seller or Depositor, as applicable, shall repurchase or, subject
to the limitations set forth in Section 2.04(b), substitute one or more
Replacement Mortgage Loans for the affected Mortgage Loan within 90 days of the
earlier of discovery or receipt of such notice with respect to such affected
Mortgage Loan. Any such repurchase or substitution shall be made in the same
manner as set forth in Section 2.04(a) above, if made by the Seller. The Trustee
shall re-convey to the Seller the Mortgage Loan to be released pursuant hereto
in the same manner, and on the same terms and conditions, as it would a Mortgage
Loan repurchased for breach of a representation or warranty.

         (d) The Seller indemnifies and holds the Trust Fund, the Trustee, the
Depositor and each Certificateholder harmless against any and all taxes, claims,
losses, penalties, fines, forfeitures, reasonable legal fees and related costs,
judgments, and any other costs, fees and expenses that the Trust Fund, the
Trustee, the Depositor and any Certificateholder may sustain in connection with
any actions of such party relating to a repurchase of a Mortgage Loan other than
in compliance with the terms of this Section 2.04 and the Mortgage Loan Purchase
and Sale Agreement, to the extent that any such action causes (i) any federal or
state tax to be imposed on the Trust Fund, including without limitation, any
federal tax imposed on "prohibited transactions" under Section 860F(a)(1) of the
Code or on "contributions after the startup date" under Section 860G(d)(1) of
the Code, or (ii) any REMIC formed hereby to fail to qualify as a REMIC at any
time that any Certificate is outstanding.

         Section 2.05      Grant Clause.

         (a) 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: (1) the
rights and obligations of the parties shall be established pursuant to the terms
of this Agreement; (2) 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
(3) 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.

         (b) The Depositor shall, to the extent consistent with this Agreement,
take such reasonable actions as may be necessary to ensure that, if this
Agreement were deemed to create a security interest in the Mortgage Loans and
the other property described above, such security interest would be deemed to be
a perfected security interest of first priority under applicable law and will be
maintained as such throughout the term of this Agreement. The Depositor will, at
its own expense, make all initial filings on or about the Closing Date and shall
forward a copy of such filing or filings to the Trustee. Without limiting the
generality of the foregoing, the Depositor shall prepare and forward for filing,
or shall cause to be forwarded for filing, at the expense of the Depositor, all
filings necessary to maintain the effectiveness of any original filings
necessary under the relevant UCC to perfect the Trustee's security interest in
or lien on the Mortgage Loans and the other property described above, including
without limitation (x) continuation statements, and (y) such other statements as
may be occasioned by (1) any change of name of the Seller, the Depositor or the
Trustee, (2) any change of location of the place of business or the chief
executive office of the Seller or the Depositor, (3) any transfer of any
interest of the Seller or the Depositor in any Mortgage Loan or (4) any change
under the relevant UCC or other applicable laws. None of the Seller or the
Depositor shall organize under the law of any jurisdiction other than the State
under which each is organized as of the Closing Date (whether changing its
jurisdiction of organization or organizing under an additional jurisdiction)
without giving 30 days prior written notice of such action to its immediate and
intermediate transferee, including the Trustee. Before effecting such change,
the Seller or the Depositor proposing to change its jurisdiction of organization
shall prepare and file in the appropriate filing office any financing statements
or other statements necessary to continue the perfection of the interests of its
immediate and mediate transferees, including the Trustee, in the Mortgage Loans
and the other property described above. In connection with the transactions
contemplated by this Agreement, each of the Seller and the Depositor authorizes
its immediate or mediate transferee to file in any filing office any initial
financing statements, any amendments to financing statements, any continuation
statements, or any other statements or filings described in this paragraph (b).

                                   ARTICLE III

                                THE CERTIFICATES

         Section 3.01      The Certificates.

         (a) The Certificates shall be issuable in registered form only and
shall be securities governed by Article 8 of the New York Uniform Commercial
Code. The Book-Entry Certificates will be evidenced by one or more certificates,
beneficial ownership of which will be held in the dollar denominations in
Certificate Principal Amount, or Notional Amount, as applicable, or in the
Percentage Interests, specified herein. Each Class of Book-Entry Certificates
will be issued 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. Each Class of Non-Book-Entry Certificates
other than the Residual Certificates shall be issued in definitive, fully
registered form in the minimum denominations in Certificate Principal Amount
specified in the Preliminary Statement hereto and in integral multiples of $1 in
excess thereof. The Residual Certificates shall be issued as single Certificates
and maintained in definitive, fully registered form in a denomination equal to
100% of the Percentage Interest of each such Class. The Class X-A-1, Class
X-A-2, Class X-B Certificates shall each be issued as single Certificates in a
denomination equal to 100% of the Percentage Interest of each such Class.

         (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 or an Authenticating Agent upon
the order of the Depositor upon receipt by the Trustee of the Trustee 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 of an
Authenticating Agent, 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 Trustee 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 B-3, Class B-4, Class B-5, Class B-6, Class X-B
Certificates offered and sold in reliance on the exemption from registration
under Rule 144A under the Act 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").

         Section 3.02      Registration.

         The Trustee is hereby appointed, and the Trustee hereby accepts its
appointment as, initial Certificate Registrar in respect of the Certificates and
shall maintain books for the

<PAGE>

registration and for the transfer of Certificates (the "Certificate Register").
The Trustee may appoint a bank or trust company to act as successor 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, 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
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 (or Notional Amount) as the
Certificate being transferred. No service charge shall be made to a
Certificateholder for any registration of transfer of Certificates, but the
Certificate Registrar may require payment of a sum sufficient to cover any tax
or governmental charge that may be imposed in connection with any registration
of transfer of Certificates.

         (b) A Certificate may be exchanged by the Holder thereof for any number
of new Certificates of the same Class, in authorized denominations, representing
in the aggregate the same Certificate Principal Amount (or Notional 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
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, 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.

<PAGE>

         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 an affiliate (as defined in Rule 405 under the 1933 Act)
         of the Depositor or (y) being made to a "qualified institutional buyer"
         (a "QIB") as defined in Rule 144A under the Securities Act of 1933, as
         amended (the "Act") by a transferor that has provided the Certificate
         Registrar with a certificate in the form of Exhibit G hereto; and

                  (ii)     The Certificate Registrar shall register the transfer
         of a Restricted Certificate if the requested transfer is being made to
         an "accredited investor" under Rule 501(a)(1), (2), (3) or (7) under
         the Act, or to any Person all of the equity owners in which are such
         accredited investors, by a transferor who furnishes to the Certificate
         Registrar a letter of the transferee substantially in the form of
         Exhibit H hereto.

         (d) No transfer of an ERISA-Restricted Certificate in the form of a
Definitive Certificate shall be made to any Person unless the Certificate
Registrar has received (A) a certificate substantially in the form of Exhibit I
hereto from such transferee or (B) an Opinion of Counsel satisfactory to the
Certificate Registrar to the effect that the purchase and holding of such a
Certificate will not constitute or result in the assets of the Trust Fund being
deemed to be "plan assets" subject to the prohibited transactions provisions of
ERISA, Section 4975 of the Code, or any provisions of applicable federal, state
or local law substantially similar to the foregoing provisions of ERISA or the
Code ("Similar Law"), and will not subject the Trustee, the Certificate
Registrar or the Depositor to any obligation in addition to those undertaken in
the Agreement; provided, however, that the Certificate Registrar 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 Certificate Registrar has
rendered an opinion to the effect that the purchase and holding of an
ERISA-Restricted Certificate by a Plan or a Person that is purchasing or holding
such a Certificate with the assets of a Plan will not constitute or result in a
prohibited transaction under ERISA, Section 4975 of the Code or Similar Law. The
preparation and delivery of the certificates and opinions referred to above
shall not be an expense of the Trust Fund, the Trustee, the Certificate
Registrar or the Depositor.

         Notwithstanding the foregoing, no Opinion of Counsel or certificate
shall be required for the initial issuance of the ERISA-Restricted Certificates.
Notwithstanding anything to the contrary herein, any purported transfer of an
ERISA-Restricted Certificate to or on behalf of an employee benefit plan subject
to Title I of ERISA or a plan subject to Section 4975 of the Code or a plan
subject to Similar Law without the delivery to the Certificate Registrar of a
certificate substantially in the form of Exhibit I hereto or an Opinion of
Counsel satisfactory to the Certificate Registrar as described above shall be
void and of no effect. The Trustee, the Certificate Registrar and the Depositor
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 the Paying Agent making any payments due on such Certificate to
the Holder thereof or taking any other action with respect to such Holder under
the provisions of this Agreement so long as the transfer was registered by the
Certificate Registrar in accordance with

<PAGE>

the foregoing requirements. The last preceding Holder of such Certificate that
is not a plan or a Person acting on behalf of a plan shall be entitled to
recover from any purported Holder of any ERISA-Restricted Certificate that was
in fact an employee benefit plan subject to Title I of ERISA or a plan subject
to Section 4975 of the Code or a plan subject to 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; provided that none of the Depositor, the Certificate Registrar or the
Trustee shall be responsible for such recovery if they otherwise made a good
faith effort to comply with this Section 3.03(d).

         (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 a Certificate.

         (f) Notwithstanding anything to the contrary contained herein, no
Residual Certificate or beneficial interest therein may be owned, pledged or
transferred, directly or indirectly, by or to (i) a Disqualified Organization or
(ii) an individual, corporation or partnership or other person unless such
person is (A) not a Non-U.S. Person or (B) is a Non-U.S. Person that holds a
Residual Certificate in connection with the conduct of a trade or business
within the United States and has furnished the transferor and the Certificate
Registrar 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 or a beneficial interest therein,
the proposed transferee shall deliver to the Trustee and the Certificate
Registrar an affidavit in substantially the form attached hereto as Exhibit B
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 and the Certificate Registrar an affidavit in substantially the
form attached hereto as Exhibit C. In addition, the Trustee or the Certificate
Registrar 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 Trustee and the Certificate Registrar, 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 a 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 Depositor, the Certificate Registrar and the

<PAGE>

Trustee shall be under no 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 Paying Agent making
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 Certificate Registrar 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, or an agent or nominee thereof, or
Non-permitted Foreign Holder. The Certificate Registrar shall be entitled to
recover from any Holder of a Residual Certificate that was a Disqualified
Organization, agent or nominee thereof, or Non-permitted Foreign Holder at the
time it became a Holder or any subsequent time it became a Disqualified
Organization, agent or nominee thereof, or Non-permitted Foreign Holder, all
payments made on such Residual Certificate at and after either such times (and
all costs and expenses, including but not limited to attorneys' fees, incurred
in connection therewith). Any payment (not including any such costs and
expenses) so recovered by the Certificate Registrar 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), such transfer shall be absolutely null and void and shall vest no
rights in the purported transferee and 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 Depositor, the
Certificate Registrar and 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), or for the Paying Agent 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 or Certificate Owner of a Restricted Certificate,
ERISA-Restricted Certificate or Residual Certificate, or an interest therein, by
such Holder's or Owner's acceptance thereof, shall be deemed for all purposes to
have consented to the provisions of this section.

         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 the Certificate Registrar or (ii) the Trustee or the Certificate Registrar
receives evidence to its satisfaction of the destruction, loss or theft of any
Certificate, and there is delivered to the Trustee and the Certificate Registrar
such security or indemnity as may be required by them to save each of them

<PAGE>

harmless, then, in the absence of notice to the Depositor, the Trustee or the
Certificate Registrar that such destroyed, lost or stolen Certificate has been
acquired by a protected purchaser, the Trustee shall execute and the
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, the Depositor or the
Certificate Registrar 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, the Depositor or
the Certificate Registrar) 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.

         If after the delivery of such new Certificate, a protected purchaser of
the original Certificate in lieu of which such new Certificate was issued
presents for payment such original Certificate, the Depositor, the Certificate
Registrar and the Trustee or any agent shall be entitled to recover such new
Certificate from the Person to whom it was delivered or any Person taking
therefrom, except a protected purchaser, and shall be entitled to recover upon
the security or indemnity provided therefor to the extent of any loss, damage,
cost or expenses incurred by the Depositor, the Certificate Registrar, the
Trustee or any agent in connection therewith.

         Section 3.06      Persons Deemed Owners.

         Subject to the provisions of Section 3.09 with respect to Book-Entry
Certificates, the Depositor, the Trustee, the Certificate Registrar, the Paying
Agent and any agent of any of them shall 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 Trustee, the Certificate Registrar, the Paying Agent 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 the Authenticating Agent shall
authenticate and deliver temporary Certificates that are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Certificates in lieu of which they
are issued and with such variations as the authorized officers executing such
Certificates may determine, as evidenced by their execution of such
Certificates.

         (b) If temporary Certificates are issued, the Depositor will cause
definitive Certificates to be prepared without unreasonable delay. After the
preparation of definitive Certificates, the temporary Certificates shall be
exchangeable for definitive Certificates upon surrender of the temporary
Certificates at the office or agency of the Certificate Registrar without charge
to the Holder. Upon surrender for cancellation of any one or more temporary
Certificates, the Trustee shall execute and the Authenticating Agent shall
authenticate and deliver in exchange therefor a like aggregate Certificate
Principal Amount (or Notional Amount) of definitive Certificates of

<PAGE>

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 any 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 (which shall be the Distribution 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. 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 Certificate Registrar, the Paying Agent and the
         Trustee shall 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 and shall be responsible for crediting the amount of such
         distributions to the accounts of such Persons entitled thereto, in
         accordance with the Clearing Agency's normal procedures;

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

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

<PAGE>

         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 Clearing Agency or the Depositor advises the Paying
Agent 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 Depositor is unable to locate a qualified successor
satisfactory to the Depositor and the Paying Agent, (ii) the Depositor, at its
option, advises the Paying Agent 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 (or Class Notional
Amount) of a Class of Book-Entry Certificates advise the Paying Agent 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 Certificate Registrar shall 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
Certificate Registrar of the Book-Entry Certificates by the Clearing Agency,
accompanied by registration instructions from the Clearing Agency for
registration, the Certificate Registrar shall issue the Definitive Certificates.
Neither the Depositor, the Certificate Registrar 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 Certificate Registrar, to the extent applicable, with respect
to such Definitive Certificates and the Certificate Registrar shall recognize
the holders of the Definitive Certificates as Certificateholders hereunder.
Notwithstanding the foregoing, the Certificate Registrar, upon the instruction
of the Depositor, shall have the right to issue Definitive Certificates on the
Closing Date in connection with credit enhancement programs.

                                   ARTICLE IV

                        ADMINISTRATION OF THE TRUST FUND

         Section 4.01      Custodial Accounts; Distribution Account.

         (a) On or prior to the Closing Date, the Servicer shall establish and
maintain one or more Custodial Accounts, as provided in the Servicing Agreement,
into which all Scheduled Payments and unscheduled payments with respect to the
Mortgage Loans, net of any deductions or reimbursements permitted under the
Servicing Agreement, shall be deposited. Prior to 1:00 p.m. New York City time
on each Distribution Account Deposit Date, the Servicer shall remit to the

<PAGE>

Trustee for deposit into the Distribution Account, all amounts so required to be
deposited into such account in accordance with the terms of the Servicing
Agreement.

         (c) In the event Servicer has remitted in error to the Distribution

                    DISTRIBUTIONS TO HOLDERS OF CERTIFICATES

         Section 5.01      Distributions Generally.

         (a) Subject to Section 7.01 respecting 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 or, upon written request made
to the Trustee at least five Business Days prior to the related Record Date by
any Certificateholder owning an aggregate initial Certificate Principal Amount
of at least $1,000,000, or in the case of a Class of Interest-Only Certificates
or Residual Certificate, a Percentage Interest of not less than 100%, by wire
transfer in immediately available funds to an account specified in the request
and at the expense of such Certificateholder; provided, however, that the final
distribution in respect of any Certificate shall be made only upon presentation
and surrender of such Certificate at the Certificate Registrar's Corporate Trust
Office; provided, further, that the foregoing provisions shall not apply to any
Class of Certificates as long as such Certificate remains a Book-Entry
Certificate in which case all payments made shall be made through the Clearing
Agency and its Clearing Agency Participants. 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 Certificates and at such time
such final payment in retirement of any Residual Certificate will be made only
upon presentation and surrender of such Certificate at the Certificate
Registrar's Corporate Trust Office. 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 Class Principal Amounts or initial Class Notional
Amounts (or Percentage Interests).

         Section 5.02      Distributions from the Certificate Account.

         (a) On each Distribution Date, the Available Distribution Amount shall
be withdrawn by the Trustee from the Distribution Account and allocated among
the classes of Senior Certificates and Subordinate Certificates in the following

         Amount, to the payment of the Interest Distribution Amount and any
         Interest Shortfalls for each Class of Senior Certificates; provided,
         however, that on each Distribution Date, the Interest Distribution
         Amount that would otherwise be distributable to a Class of
         Interest-Only Certificates shall be deposited in the Basis Risk Reserve
         Fund to the extent of the Required Basis Risk Deposit for such Class
         and shall not be distributed to such Class;

<PAGE>

                  (ii)     To the Senior Certificates from the Available
         Distribution Amount after application of amounts pursuant to clause (i)
         above, the Senior Principal Distribution Amount first to the Class A-R
         Certificates and then second, to the Class A-1 and Class A-2
         Certificates, pro rata, based upon their Class Principal Amounts, until
         their respective Class Principal Amounts have been reduced to zero; and

                  (iii)    From the Available Distribution Amount remaining
         after the application of amounts pursuant to clauses (i) and (ii)
         above, to the Class B-1, Class B-2 and Class B-3 Certificates,
         sequentially, in that order, the Interest Distribution Amount and any
         Interest Shortfalls, in each case, for such Class on such date;

                  (iv)     From the Available Distribution Amount remaining
         after application of amounts pursuant to clauses (i) through (iii)
         above, to the Class B-1, Class B-2 and Class B-3 Certificates,
         sequentially, in that order, such Class' Subordinate Class Percentage
         of the Subordinate Principal Distribution Amount, until its Class
         Principal Amount has been reduced to zero;

                  (v)      [Reserved;]

                  (vi)     From the remaining Available Distribution Amount in
         the aggregate remaining after application of amounts pursuant to
         clauses (i) through (v) in the following order of priority:

                           (A)      to the Class B-4 Certificates, the Interest
                  Distribution Amount and any Interest Shortfalls, in each case,
                  for such Class and date;

                           (B)      to the Class B-4 Certificates, such Class'
                  Subordinate Class Percentage of the Subordinate Principal
                  Distribution Amount, until its Class Principal Amount has been
                  reduced to zero;

                           (C)      to the Class B-5 Certificates, the Interest
                  Distribution Amount and any Interest Shortfalls, in each case,
                  for such Class and date;

                           (D)      to the Class B-5 Certificates, such Class'
                  Subordinate Class Percentage of the Subordinate Principal
                  Distribution Amount, until its Class Principal Amount has been
                  reduced to zero;

                           (E)      to the Class B-6 Certificates, the Interest
                  Distribution Amount and any Interest Shortfalls, in each case,
                  for such Class and date; and

                           (F)      to the Class B-6 Certificates, such Class'
                  Subordinate Class Percentage of the Subordinate Principal
                  Distribution Amount, until its Class Principal Amount has been
                  reduced to zero;

                  (vii)    To the Class A-R Certificate, any remaining amount of
         the Available Distribution Amount allocated as provided in Section
         5.02(d).

<PAGE>

         (b) On each Distribution Date on and after the Credit Support Depletion
Date, the Available Distribution Amount shall be distributed to the remaining
Classes of Certificates, on a pro rata basis, first, to pay the Interest
Distribution Amount and any accrued but unpaid Interest Shortfalls; second, to
pay the Senior Principal Distribution Amount; and third, to the Class A-R
Certificate, any remaining Available Distribution Amount.

         (c) Notwithstanding the priority and allocation set forth in Section
5.02(a)(iv) and Section 5.02(a)(vi) above, if with respect to any Class of
Subordinate Certificates on any Distribution Date the sum of the related Class
Subordination Percentages of such Class and of all other Classes of Subordinate
Certificates which have a higher numerical Class designation than such Class is
less than the Original Applicable Credit Support Percentage for such Class, no
distribution of Principal Prepayments shall be made to any such Classes and the
amount of such Principal Prepayment otherwise distributable to such Classes
shall be distributed to any Classes of Subordinate Certificates having lower
numerical Class designations than such Class, pro rata, based on the Class
Principal Amounts of the respective Classes immediately prior to such
Distribution Date and shall be distributed in the sequential order provided in
Section 5.02(a)(iv) and Section 5.02(a)(vi) above.

         (d) Amounts distributed to the Residual Certificates pursuant to
subparagraph (a)(vii) of this Section 5.02 on any Distribution Date shall be
allocated among the REMIC residual interests represented thereby such that each
such interest is allocated the excess of funds available to the related REMIC
over required distributions to the regular interests in such REMIC on such
Distribution Date.

         (e) [Reserved].

         (f) To the extent a Basis Risk Shortfall is experienced on the Class
A-1, Class A-2, Class A-R, Class B-1, Class B-2 or Class B-3 Certificates, the
Trustee shall withdraw from the Class X-A-1 Sub-account of the Basis Risk
Reserve Fund, for payment to the Class A-1 and Class A-R Certificates,
concurrently, in proportion to any Basis Risk Shortfalls and Unpaid Basis Risk
Shortfalls related to such Classes for such Distribution Date, from the Class
X-A-2 Sub-account of the Basis Risk Reserve Fund, for payment to the Class A-2
Certificates, any Basis Risk Shortfalls or related Unpaid Basis Risk Shortfall
related to such Class for such Distribution Date and from the Class X-B
Sub-account of the Basis Risk Reserve Fund for payment to the Class B-1, Class
B-2 and Class B-3 Certificates, sequentially in that order, any related Basis
Risk Shortfall or related Unpaid Basis Risk Shortfall for such date up to in
each case the amounts available therefor on deposit in the related Sub-account
as provided in Section 5.06.

         (g) For purposes of distributions of interest in paragraph (a) of this
Section 5.02 such distributions to a Class of Certificates on any Distribution
Date shall be made first, in respect of Current Interest; and second, in respect
of Interest Shortfalls.

         Section 5.03      Allocation of Losses.

         (a) On or prior to each Distribution Date, the Trustee shall aggregate
the information provided by each Servicer with respect to the total amount of
Realized Losses, including Excess Losses, with respect to the Mortgage Loans for
the related Distribution Date.

<PAGE>

         (b) On each Distribution Date, the principal portion of Realized
Losses, Bankruptcy Losses, Fraud Losses and Special Hazard Losses with respect
to such Distribution Date shall be allocated as follows:

                  (i)      Realized Losses, Bankruptcy Losses, Fraud Losses and
         Special Hazard Losses (other than Excess Losses) shall be allocated in
         the following order:

                           first, to the Classes of Subordinate Certificates in
                  reverse order of their respective numerical Class designations
                  (beginning with the Class of Subordinate Certificates with the
                  highest numerical Class designation) until the Class Principal
                  Amount of each such Class is reduced to zero; and

                           second, to each Class of Senior Certificates, until
                  the Class Principal Amount of each Class of Senior
                  Certificates is reduced to zero;

                  (ii)     the principal portion of any Excess Losses shall be
         allocated proportionately on a pro rata basis to the Certificates on
         the basis of their Class Certificate Principal Amounts.

                  (iii)    The Class Principal Amount of the Class of
         Subordinate Certificates then outstanding with the highest numerical
         Class designation shall be reduced on each Distribution Date by the
         amount, if any, by which the aggregate of the Class Principal Amounts
         of all outstanding Classes of Certificates (after giving effect to the
         distribution of principal and the allocation of Realized Losses,
         Bankruptcy Losses, Fraud Losses and Special Hazard Losses and Excess
         Losses on such Distribution Date) exceeds the Aggregate Stated
         Principal Balance for the following Distribution Date.

                  (iv)     Any allocation of a loss pursuant to this section to
         a Class of Certificates shall be achieved by reducing the Class
         Principal Amount thereof by the amount of such loss.

Notwithstanding the foregoing, the first $0.16 of the principal portion of
Realized Losses shall not be allocated to any Class of Certificates.

         Section 5.04      Advances.

         If the Servicer fails to remit any Advance required to be made under
the Servicing Agreement, the Trustee solely in its capacity as successor
Servicer shall itself make, or shall cause the successor Servicer to make, such
Advance. If the Trustee solely in its capacity as successor Servicer determines
that an Advance is required, it shall on the Business Day preceding the related
Distribution Date immediately following such Determination Date remit from its
own funds (or funds advanced by the Servicer) for deposit in the Distribution
Account immediately available funds in an amount equal to such Advance. The
Trustee and the Servicer shall be entitled to be reimbursed for all Advances
made by it. Notwithstanding anything to the contrary herein, in the event the
Trustee (or successor servicer) determines in its reasonable judgment that an
Advance is non-recoverable, the Trustee (or successor servicer) shall be under
no obligation to make such Advance.

         Section 5.05      [Reserved.]

         Section 5.06      Basis Risk Reserve Fund.

         (a) On the Closing Date, the Trustee shall establish and maintain in
the Trustee's name, in trust for the benefit of the holders of the LIBOR
Certificates and the Interest Only Certificates, a Basis Risk Reserve Fund, into
which the Depositor shall deposit $10,000. The Basis Risk Reserve Fund shall be
an Eligible Account, and funds on deposit therein shall be held separate and
apart from, and shall not be commingled with, any other moneys, including,
without limitation, other moneys of the Trustee held pursuant to this Agreement.
The Basis Risk Reserve Fund shall not be an asset of any REMIC established
hereby. The parties hereto intend that each of the Class X-A-1 Sub-account, the
Class X-A-2 Sub-account and the Class X-B Sub-account shall be treated for
federal income tax purposes as a "grantor trust" under Subpart E of Part I of
Subchapter J of the Code. The Trustee shall prepare, sign and file all tax
returns, including returns on Internal Revenue Service Form 1041 or any
successor form, required to be filed with respect to such grantor trusts.

         (b) The Basis Risk Reserve Fund will be comprised of three
Sub-accounts: the "Class X-A-1 Sub-account," the "Class X-A-2 Sub-account"and
the "Class X-B Sub-account." On each Distribution Date, (i) Current Interest
that would otherwise be distributable with respect to the Class X-A-1
Certificates shall instead be deposited in the Class X-A-1 Sub-account to the
extent of the applicable Class X-A-1 Required Basis Risk Deposit, (ii) Current
Interest that would otherwise be distributable with respect to the Class X-A-2
Certificates shall instead be deposited in the Class X-A-2 Sub-account to the
extent of the applicable Class X-A-2 Required Basis Risk Deposit and (iii)
Current Interest that would otherwise be distributable with respect to the Class
X-B Certificates shall instead be deposited in the Class X-B Sub-account to the
extent of the Class X-B Required Basis Risk Deposit.

         (c) On any Distribution Date for which a Basis Risk Shortfall exists
with respect to the Class A-1 Certificates or Class A-R Certificates, the
Trustee shall withdraw from the Class X-A-1 Sub-account the amount of such Basis
Risk Shortfall for distribution on such Distribution Date pursuant to Section
5.02(f).

         (d) On any Distribution Date for which a Basis Risk Shortfall exists
with respect to the Class A-2 Certificates, the Trustee shall withdraw from the
Class X-A-2 Sub-account the amount of such Basis Risk Shortfall for distribution
on such Distribution Date pursuant to Section 5.02(f).

         (e) On any Distribution Date for which a Basis Risk Shortfall exists
with respect to the Class B-1, Class B-2 and Class B-3 Certificates, the Trustee
shall withdraw from the Class X-B Sub-account the amount of such Basis Risk
Shortfall for distribution on such Distribution Date pursuant to Section
5.02(f).

         (f) Funds in each of the Class X-A-1 Sub-account, the Class X-A-2
Sub-account and the Class X-B Sub-account, if invested, shall be invested in
Permitted Investments. Any earnings on amounts in the Class X-A-1 Sub-account
shall be for the benefit of the Class X-A-1 Certificateholders, any earnings on
amounts in the Class X-A-2 Sub-account shall be for the

<PAGE>

benefit of the Class X-A-2 Certificateholders and any earnings on amounts in the
Class X-B Sub-account shall be for the benefit of the Class X-B
Certificateholders. The Interest-Only Certificates shall evidence ownership of
the related Sub-account for federal income tax purposes. Funds on deposit on in
the Basis Risk Reserve Fund, if invested, shall be invested in Permitted
Investments described in clause (i) of the definition of "Permitted Investments"
maturing prior to the next Distribution Date and no such investment shall be
sold or otherwise disposed of prior to maturity. The applicable Interest-Only
Certificateholder(s) shall be liable for any losses incurred on such
investments. For all Federal income tax purposes, amounts transferred by the
Upper Tier REMIC to the Basis Risk Reserve Fund shall be treated as amounts
distributed by the Upper Tier REMIC to the applicable Interest-Only
Certificateholders. Absent written direction provided to the Trustee from all of
the Holders of the Class X-A-1 Certificates, in the case of funds in the Class
X-A-1 Sub-account, from all of the Holders of the Class X-A-2 Certificates, in
the case of funds in the Class X-A-2 Sub-account, and all of the Holders of the
Class X-B Certificates, in the case of funds in the Class X-B Sub-account, funds
on deposit in the Basis Risk Reserve Fund shall remain uninvested.

         (g) Upon termination of the Trust Fund any amounts remaining in the
related Sub-account shall be distributed to the applicable Interest-Only
Certificateholders.

         (a) The Trustee, except during the continuance of an Event of Default
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 has occurred and has not otherwise been cured or waived, the Trustee

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 Servicer to the Trustee pursuant to this Agreement or the
Servicing Agreement, and shall not be required to recalculate or verify any
numerical information furnished to the Trustee pursuant to this Agreement.
Subject to the immediately preceding sentence, if any such resolution,
certificate, statement, opinion, report, document, order or other instrument is
found not to conform to the form required by this Agreement in a material manner
the Trustee shall take such action as it deems appropriate to cause the
instrument to be corrected, and if the instrument is not corrected to the
Trustee's satisfaction, the Trustee will provide notice thereof to the
Certificateholders and will, at the

<PAGE>

expense of the Trust Fund, which expense shall be reasonable given the scope and
nature of the required action, take such further action as directed by the
Certificateholders.

         (c) The Trustee shall not have any liability arising out of or in
connection with this Agreement, except for its negligence or willful misconduct.
Notwithstanding anything in this Agreement to the contrary, the Trustee shall
not be liable for special, indirect or consequential losses or damages of any
kind whatsoever (including, but not limited to, lost profits). 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 direction of Holders of Certificates
         as provided in Section 6.18 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 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 of the Trustee, and such notice references the Holders of the
         Certificates and this Agreement;

                  (iii)    No provision of this Agreement shall require the
         Trustee to expend or risk its own funds or otherwise incur any
         financial liability in the performance of any of its duties hereunder,
         or in the exercise of any of its rights or powers, if it shall have
         reasonable grounds for believing that repayment of such funds or
         adequate indemnity against such risk or liability is not reasonably
         assured to it; and none of the provisions contained in this Agreement
         shall in any event require the Trustee to perform, or be responsible
         for the manner of performance of, any of the obligations of the
         Servicer under the Servicing Agreement;

                  (iv)     The Trustee shall not be responsible for any act or
         omission of the Servicer, the Depositor or the Seller.

         (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 promptly remit to the Servicer upon receipt any such
complaint, claim, demand, notice or other document (i) which is delivered to the
Corporate Trust Office of the Trustee, (ii) of which a Responsible Officer has
actual knowledge, and (iii) which contains information sufficient to permit the
Trustee to make a determination that the real property to which such document
relates is a Mortgaged Property.

         (e) The Trustee shall not be personally liable with respect to any
action taken, suffered or omitted to be taken by it in good faith in accordance
with the direction of the Certificateholders of any Class holding Certificates
which evidence, as to such Class, Percentage Interests

<PAGE>

aggregating not less than 25% as to the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred upon the Trustee under this Agreement.

         (f) The Trustee shall not be required to perform services under this
Agreement, or to expend or risk its own funds or otherwise incur financial
liability for the performance of any of its duties hereunder or the exercise of
any of its rights or powers if there is reasonable ground for believing that the
timely payment of its fees and expenses or the 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 Servicer under the Servicing Agreement except
during such time, if any, as the Trustee shall be the successor to, and be
vested with the rights, duties, powers and privileges of, the Servicer in
accordance with the terms of the Servicing Agreement.

         (g) The Trustee shall not be held liable by reason of any insufficiency
in the Distribution Account or the Basis Risk Reserve Fund resulting from any
investment loss on any Permitted Investment included therein (except to the
extent that the Trustee is the obligor and has defaulted thereon).

         (h) Except as otherwise provided herein, the Trustee shall not have any
duty (A) to see to any recording, filing, or depositing of this Agreement or any
agreement referred to herein or any financing statement or continuation
statement evidencing a security interest, or to see to the maintenance of any
such recording or filing or depositing or to any rerecording, refiling or
redepositing of any thereof, (B) to see to any insurance, (C) to see to the
payment or discharge of any tax, assessment, or other governmental charge or any
lien or encumbrance of any kind owing with respect to, assessed or levied
against, any part of the Trust Fund other than from funds available in the
Distribution Account, or (D) to confirm or verify the contents of any reports or
certificates of the Servicer delivered to the Trustee pursuant to the Servicing
Agreement believed by the Trustee to be genuine and to have been signed or
presented by the proper party or parties.

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

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

         consent,

<PAGE>

         order, approval, bond or other paper or document believed by it to be
         genuine and to have been signed or presented by the proper party or
         parties;

                  (ii)     The Trustee may consult with counsel and any advice

         advice or Opinion of Counsel;

                  (iii)    The Trustee shall not be personally liable for any

         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, consent,
         order, approval, bond or other paper or document (provided the same
         appears regular on its face), unless requested in writing to do so by
         the Holders of at least a majority in Class Principal Amount (or
         Percentage Interest) of each Class of Certificates; provided, however,
         that, if the payment within a reasonable time to the Trustee of the
         costs, expenses or liabilities likely to be incurred by it in the
         making of such investigation is, in the opinion of the Trustee, not
         reasonably assured to the Trustee by the security afforded to it by the
         terms of this Agreement, the Trustee may require reasonable indemnity
         against such expense or liability or payment of such estimated expenses
         from the Certificateholders as a condition to proceeding. The
         reasonable expense thereof shall be paid by the party requesting such
         investigation and if not reimbursed by the requesting party shall be
         reimbursed to the Trustee by the Trust Fund;

                  (v)      The Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents, custodians or attorneys, which agents, custodians or
         attorneys shall have any and all of the rights, powers, duties and

         Certificateholders pursuant to the provisions of this Agreement, unless

         may be incurred therein or thereby;

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

<PAGE>

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

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

         The Trustee hereunder shall at all times (i) be an institution insured
by the FDIC, (ii) a corporation or national banking association, organized and

examination by federal or state authority and (iii) not be an Affiliate of the
Servicer. If such corporation or national banking association publishes reports

banking association shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. In case at any
time the Trustee shall cease to be eligible in accordance with provisions of
this Section, the Trustee shall resign immediately in the manner and with the
effect specified in Section 6.06.

Servicer. Upon receiving such notice of resignation, the Depositor will promptly
appoint a successor trustee by written instrument, one copy of which instrument
shall be delivered to the resigning Trustee, one copy to the successor trustee
and one copy to the Servicer. If no successor trustee shall have been so
appointed and shall have accepted appointment within 30 days after the giving of
such notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor trustee.

         (b) If at any time (i) the Trustee shall cease to be eligible in
accordance with the provisions of Section 6.05 and shall fail to resign after
written request therefor by the Depositor, (ii) the Trustee shall become
incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver
of the Trustee of its property shall be appointed, or any public officer shall
take charge or control of the Trustee or of either of their property or affairs
for the purpose of rehabilitation, conservation or liquidation, (iii) a tax is
imposed or threatened with respect to the Trust Fund by any state in which the
Trustee or the Trust Fund held by the Trustee is located, or (iv) the continued
use of the Trustee would result in a downgrading of the rating by any Rating
Agency of any Class of Certificates with a rating, then the Depositor shall
remove the Trustee and the Depositor shall appoint a successor trustee by
written instrument, one copy of which instrument shall be delivered to the
Trustee so removed, one copy each to the successor trustee and one copy to the
Servicer.

         (c) The Holders of more than 50% of the Class Principal Amount (or
Percentage Interest) of each Class of Certificates may at any time upon 30 days'
written notice to the Trustee and to the Depositor remove the Trustee by such

trustee in accordance with this Section.

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

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

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

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

         Section 6.08      Merger or Consolidation of Trustee.

         Any Person into which the Trustee may be merged or with which it may be
consolidated, or any Person resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any Persons succeeding
to the business of the Trustee shall be the successor to the Trustee hereunder,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto, anything herein to the contrary notwithstanding,

the provisions of Section 6.05.

         Section 6.09      Appointment of Co-Trustee, Separate Trustee or
                           Custodian.

         (a) Notwithstanding any other provisions hereof, at any time, the
Trustee, the Depositor or the Certificateholders evidencing more than 50% of the
Class Principal Amount (or Percentage Interest) of every Class of Certificates
shall have the power from time to time to appoint one or more Persons, approved
by the Trustee, to act either as co-trustees jointly with the Trustee, or as
separate trustees, or as custodians, for the purpose of holding title to,
foreclosing or otherwise taking action with respect to any Mortgage Loan outside
the state where the Trustee has its principal place of business where such
separate trustee or co-trustee is necessary or advisable (or the Trustee has
been advised by the Servicer that such separate trustee or co-trustee

<PAGE>

is necessary or advisable) under the laws of any state in which a property
securing a Mortgage Loan is located or for the purpose of otherwise conforming
to any legal requirement, restriction or condition in any state in which a
property securing a Mortgage Loan is located or in any state in which any
portion of the Trust Fund is located. The separate Trustees, co-trustees, or
custodians so appointed shall be trustees or custodians for the benefit of all
the Certificateholders and shall have such powers, rights and remedies as shall
be specified in the instrument of appointment; provided, however, that no such
appointment shall, or shall be deemed to, constitute the appointee an agent of
the Trustee. The obligation of the Trustee to make Advances pursuant to Section
5.04 hereof shall not be affected or assigned by the appointment of a
co-trustee.

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

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

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

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

                  (iv)     the Trustee may at any time, by an instrument in
         writing executed by it, with the concurrence of the Depositor, accept
         the resignation of or remove any separate trustee, co-trustee or
         custodian, so appointed by it or them, if such resignation or removal
         does not violate the other terms of this Agreement.

         (c) Any notice, request or other writing given to the Trustee shall be
deemed to have been given to each of the then separate trustees and co-trustees,
as effectively as if given to each of them. Every instrument appointing any
separate trustee, co-trustee or custodian shall refer to this Agreement and the
conditions of this Article VI. Each separate trustee and co-trustee, upon its
acceptance of the trusts conferred, shall be vested with the estates or property
specified in its instrument of appointment, either jointly with the Trustee or
separately, as may be provided therein, subject to all the provisions of this
Agreement, specifically including every provision of this Agreement relating to
the conduct of, affecting the liability of, or affording protection to, the
Trustee. Every such instrument shall be filed with the Trustee and a copy given
to the Servicer.

         (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

<PAGE>

do any lawful act under or in respect of this Agreement on its behalf and in its
name. 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 Trust shall pay the reasonable compensation of the co-trustees
(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. If such an agent is so appointed by the Trustee, wherever
reference is made in this Agreement to the authentication of Certificates by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication on behalf of the Trustee by an Authenticating
Agent and a certificate of authentication executed on behalf of the Trustee by
an Authenticating Agent. Each Authenticating Agent must be a corporation
organized and doing business under the laws of the United States of America or
of any state, having a combined capital and surplus of at least $15,000,000,
authorized under such laws to do a trust business and subject to supervision or
examination by federal or state authorities.

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

         (c) Any Authenticating Agent may at any time resign by giving at least
30 days' advance written notice of resignation to the Trustee and the Depositor.
The Trustee may at any time terminate the agency of any Authenticating Agent by
giving written notice of termination to such Authenticating Agent and the
Depositor. Upon receiving a notice of resignation or upon such a termination, or
in case at any time any Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section 6.10, the Trustee may appoint a
successor authenticating agent, shall give written notice of such appointment to
the Depositor and shall mail notice of such appointment to all Holders of
Certificates. Any successor authenticating agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers, duties
and responsibilities of its predecessor hereunder, with like effect as if
originally named as Authenticating Agent. No successor authenticating agent
shall be appointed unless

<PAGE>

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.

         Section 6.11      Indemnification of Trustee.

         The Trustee and its respective directors, officers, employees and
agents shall be entitled to indemnification from the Depositor and the Trust
Fund (provided that the Trust Fund's indemnification under this Section 6.11 is
limited by Section 4.01(d) for any loss, liability or expense (including,
without limitation, reasonable attorneys' fees and disbursements (and, in
connection with any custody agreement the Trustee may enter pursuant to this
Agreement, including the reasonable compensation and the expenses and
disbursements of its agents or counsel), incurred without negligence or willful
misconduct on its 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 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 written notice thereof promptly after the
         Trustee shall have knowledge thereof;

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

                  (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; and

                  (iv)     the Trust's Fund's indemnification obligations
         hereunder shall be limited to losses, liability, costs or expenses,
         payments in respect of which by the Trust Fund would constitute
         "unanticipated expenses" within the meaning of Treasury Regulations
         Section 1.860G-1(b)(3)(ii)).

         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 the Trustee.

         As compensation for its services hereunder, the Trustee shall be
entitled to retain any and all investment earnings on amounts on deposit in the
Distribution Account pending the distribution of such funds to
Certificateholders on each Distribution Date (which compensation shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust). Any expenses incurred by the Trustee shall be reimbursed in
accordance with Section 6.11.

<PAGE>

         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.

         Section 6.14      Events of Default; Trustee To Act; Appointment of
                           Successor.

         (a) If an Event of Default described in the Servicing Agreement shall
occur and be continuing, 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 the Servicing Agreement, the Trustee, by notice
in writing to the 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 Servicer under the Servicing Agreement in accordance with the
terms of the Servicing Agreement. On or after the receipt by the Servicer of
such written notice, all authority and power of the Servicer, whether with
respect to the Mortgage Loans or otherwise, shall pass to and be vested in the
Trustee; and the Trustee is hereby authorized and empowered to execute and
deliver, on behalf of the defaulting 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.

         If any Event of Default shall occur, the Trustee, upon becoming aware
of the occurrence thereof, shall promptly notify the Depositor and each Rating
Agency of the nature and extent of such Event of Default.

         (b) Within 90 days of the time the Servicer receives a notice of
termination from the Trustee pursuant to Section 6.14(a), the Trustee, unless
another Servicer shall have been appointed, shall be the successor in all
respects to the Servicer in its capacity as such under the Servicing Agreement
and the transactions set forth or provided for therein 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 Servicer
thereunder, including the obligation to make Advances; provided, however, that
any failure to perform such duties or responsibilities caused by the Servicer's
failure to provide information required by this Agreement or the Servicing
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 Servicer prior to the issuance of any notice of termination. The Trustee
shall have no liability relating to any representations and warranties of the
Servicer set forth in the Servicing Agreement. In the Trustee's capacity as such
successor, the Trustee shall have the same limitations on liability provided to
the Servicer in the Servicing Agreement. As compensation therefor, the Trustee
shall be entitled to receive all compensation payable to the Servicer under the
Servicing Agreement.

         The Trustee shall be entitled to be reimbursed by the Depositor and the
Trust Fund (pursuant to Section 6.11 but without regard to any annual limitation
thereunder), in the event

<PAGE>

that the Servicer does not reimburse the Trustee under the Servicing Agreement,
for all costs associated with the transfer of servicing from the predecessor
Servicer, including, without limitation, any costs or expenses associated with
the termination of the predecessor Servicer, the appointment of a successor
servicer, the complete transfer of all servicing data and the completion,
correction or manipulation of such servicing data as may be required by the
Trustee or any successor servicer to correct any errors or insufficiencies in
the servicing data or otherwise to enable the Trustee or successor servicer to
service the Mortgage Loans property and effectively (such costs, "Servicing
Transfer Costs").

         (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, petition a
court of competent jurisdiction to appoint, or, with the consent of the
Depositor, appoint on its own behalf any established housing and home finance
institution servicer, or servicing or mortgage servicing institution having a
net worth of not less than $15,000,000 and meeting such other standards for a
successor servicer as are set forth in the Servicing Agreement and reasonably
satisfactory to the Depositor, as the successor to the Servicer in the
assumption of all of the responsibilities, duties or liabilities of a servicer,
like the Servicer. Any entity designated by the Trustee as a successor 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 servicer, the Trustee, in its individual capacity shall agree,
at the time of such designation, to be and remain liable to the Trust Fund for
such Affiliate's actions and omissions in performing its duties under the
Servicing Agreement. 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
Servicer under the Servicing Agreement. The Trustee and such successor shall
take such actions, consistent with this Agreement and the Servicing 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 and therewith. Neither the Trustee nor any other
successor servicer shall be deemed to be in default hereunder by reason of any
failure to make, or any delay in making, any distribution hereunder or any
portion thereof caused by (i) the failure of the Servicer to deliver, or any
delay in delivering, cash, documents or records to it, (ii) the failure of the
Servicer to cooperate as required by the Servicing Agreement, (iii) the failure
of the Servicer to deliver the Mortgage Loan data to the Trustee as required by
the Servicing Agreement or (iv) restrictions imposed by any regulatory authority
having jurisdiction over the 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 the Trust Fund, 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 or the Servicing Agreement shall be exclusive of
any other remedy, and each and every remedy shall be cumulative and in addition
to

<PAGE>

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.

         More than 50% of the Aggregate Voting Interests of Certificateholders
may waive any default or Event of Default by the Servicer in the performance of
its obligations hereunder, except that a default in the making of any required
deposit to the Distribution Account that would result in a failure of the
Trustee to make any required payment of principal of or interest on the
Certificates may only be waived with the consent of 100% of the affected
Certificateholders. Upon any such waiver of a past default, such default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to
have been remedied for every purpose of this Agreement. No such waiver shall
extend to any subsequent or other default or impair any right consequent thereon
except to the extent expressly so waived.

         Section 6.17      Notification to Holders.

         Upon termination of the Servicer or appointment of a successor to the
Servicer, in each case as provided herein, the Trustee shall promptly mail
notice thereof by first class mail to the Certificateholders at their respective
addresses appearing on the Certificate Register. The Trustee shall also, within
45 days after the occurrence of any Event of Default known to the Trustee, give
written notice thereof to 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 Percentage Interest) of each Class of
Certificates affected thereby 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 or the
Servicing 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 or the Servicing 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
Servicer or any successor servicer from its rights and duties as servicer) 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 for which it is not indemnified to its
satisfaction or be unjustly prejudicial to the non-assenting Certificateholders.

<PAGE>

         Section 6.19      Preparation of Tax Returns and Other Reports.

         (a) The Trustee shall prepare or cause to be prepared on behalf of the
Trust Fund, based upon information calculated in accordance with this Agreement
pursuant to instructions given by the Depositor, and the Trustee shall file
federal tax returns, all in accordance with Article X hereof. The Trustee shall
prepare and file such state income tax returns and such other returns as may be
required by applicable law relating to the Trust Fund, and, if required by state
law, 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
distribute 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 Trustee shall prepare and provide to such Persons as may be
required by applicable law all information returns required with respect to
payments made from the Basis Risk Reserve Fund.

         (b) The Trustee shall prepare and file with the Internal Revenue
Service ("IRS"), on behalf of each of the Lower Tier REMIC and Upper Tier REMIC,
an application on IRS Form SS-4 or shall obtain a Taxpayer Identification Number
for each of the Lower Tier REMIC and the Upper Tier REMIC using another
reasonable method. If the application is filed on 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 notices to the Depositor,
upon request. The Trustee will file 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, 2004, 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, 2004, the Trustee shall file a Form 10-K
executed by the Depositor, in substance conforming to industry standards, with
respect to the Trust Fund. The Depositor shall be responsible for preparing all
filings and certificates required by the Sarbanes-Oxley Act of 2002. The Trustee
agrees to promptly furnish to the Depositor, 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 Depositor reasonably
deems appropriate to prepare and file all necessary reports with the Commission.

         Section 6.20      Annual Certificate by Trustee.

         (a) By March 15th of each year for which a Form 10-K is to be filed
with a certification by the Depositor, an officer of the Trustee shall execute
and deliver an Officer's Certificate, signed by the senior officer in charge of
the Trustee or any officer to whom that officer reports,

<PAGE>

to the Depositor for the benefit of such Depositor and its officers, directors
and affiliates, certifying as to the matters described in the Officer's
Certificate attached hereto as Exhibit P.

         (b) The Trustee shall indemnify and hold harmless the Depositor and its
officers, directors, agents and affiliates from and against any losses, damages,
penalties, fines, forfeitures, reasonable legal fees and related costs,
judgments and other costs and expenses arising out of or based upon a breach by
the Trustee or any of its officers, directors, agents or affiliates of its
obligations under this Section 6.20 any material misstatement or omission in the
Officer's Certificate required under this Section or the negligence, bad faith
or willful misconduct of the Trustee in connection therewith. If the
indemnification provided for herein is unavailable or insufficient to hold
harmless the Depositor, then the Trustee agrees that it shall contribute to the
amount paid or payable by the Depositor as a result of the losses, claims,
damages or liabilities of the Depositor in such proportion as is appropriate to
reflect the relative fault of the Trustee on the one had and the Depositor on
the other in connection with a breach of the Trustee's obligations under this
Section 6.20, any material misstatement or omission in the Officer's Certificate
required under this Section or the Trustee's negligence, bad faith or willful
misconduct in connection therewith.

                                   ARTICLE VII

                         PURCHASE OF MORTGAGE LOANS AND
                          TERMINATION OF THE TRUST FUND

         Section 7.01      Purchase of Mortgage Loans; Termination of Trust Fund
                           Upon Purchase or Liquidation of All Mortgage Loans.

         (a) The respective obligations and responsibilities of the Trustee
created hereby (other than the obligation of the Trustee to make payments to
Certificateholders as set forth in Section 7.02), shall terminate on the
earliest 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, (ii) the
sale of the property held by the Trust Fund in accordance with Section 7.01(b)
and (iii) the Latest Possible Maturity Date; 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 on or after the Initial Optional
Purchase Date, the Servicer has the option to cause the Trust Fund to adopt a
plan of complete liquidation pursuant to Section 7.03(a)(i) hereof to sell all
of its property. If the Servicer elects to exercise such option, it shall no
later than 30 days prior to the Distribution Date selected for purchase of the
assets of the Trust Fund (the "Purchase Date") deliver notices to the Trustee
and either (a) deposit in the Distribution Account the Redemption Price or (b)
state in such notice that the Redemption Price shall be deposited in the
Distribution Account not later than 10:00 a.m., New

<PAGE>

York City time on the applicable Purchase Date. Upon exercise of such option,
the property of the Trust Fund shall be sold to the Servicer at a price equal to
the Redemption Price.

         (c) The Depositor, the Servicer and the Trustee shall be reimbursed
from the Redemption Price for any Advances, Servicer Advances, accrual and
unpaid Servicing Fees or other amounts with respect to the Mortgage Loans that
are reimbursable to such parties under this Agreement or the Servicing
Agreement.

         Section 7.02      Procedure Upon Redemption or Termination of Trust
                           Fund.

         (a) Notice of any redemption termination pursuant to the provisions of
Section 7.01, specifying the Distribution Date upon which the final distribution
shall be made or the Redemption Date of the Certificates, shall be given
promptly by the Trustee by first class mail to Certificateholders mailed in the
case of a redemption of the Certificate, no less than the first day of the month
in which the Distribution Date selected for redemption of the Certificates
occurs or upon (x) the sale of all of the property of the Trust Fund by the
Trustee or in the case of a sale of assets of the Trust Fund, 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 Redemption Date, 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 Certificate
Registrar's 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
Certificate Registrar at the time such notice is given to Holders of the
Certificates. Upon any such termination, the duties of the Trustee and the
Certificate Registrar with respect to the Certificates shall terminate and the
Trustee shall terminate the Distribution Account and any other account or fund
maintained with respect to the Certificates, subject to the Trustee's obligation
hereunder to hold all amounts payable to Certificateholders in trust without
interest pending such payment.

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

         (c) Any reasonable expenses incurred by the Trustee, to the extent that
such expenses, if paid or reimbursed by the Trust Fund, would constitute
"unanticipated expenses" within the meaning of Treasury Regulations Section
1.860G-1(b)(3)(ii), in connection with any redemption

<PAGE>

or termination or liquidation of the Trust Fund shall be reimbursed from
proceeds received from the liquidation of the Trust Fund.

         Section 7.03      Additional Trust Fund Termination Requirements.

         (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 party exercising the option to purchase all of the Mortgage Loans
pursuant to Section 7.01(b)), and subsequently receives, an Opinion of Counsel
(at the expense of such requesting party), 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)      Within 89 days prior to the time of the making of the
         final payment on the Certificates, upon notification by the Depositor
         that it intends to exercise its option to cause the termination of the
         Trust Fund, the Trustee shall adopt a plan of complete liquidation of
         the Trust Fund on behalf of each REMIC, meeting the requirements of a
         qualified liquidation under the REMIC Provisions;

                  (ii)     Any sale of the assets of the Trust Fund pursuant to
         Section 7.02 shall be a sale for cash and shall occur at or after the
         time of adoption of such a plan of complete liquidation and prior to
         the time of making of the final payment on the Certificates;

                  (iii)    On the date specified for final payment of the
         Certificates, the Trustee shall make final distributions of principal
         and interest on the Certificates in accordance with Section 5.02 and,
         after payment of, or provision for any outstanding expenses, distribute
         or credit, or cause to be distributed or credited, to the Holders of
         the Residual Certificates all cash on hand after such final payment
         (other than cash retained to meet claims), and the Trust Fund (and each
         REMIC) shall terminate at that time; and

                  (iv)     In no event may the final payment on the Certificates
         or the final distribution or credit to the Holders of the Residual
         Certificates be made after the 89th day from the date on which the plan
         of complete liquidation is adopted.

         (b) By its acceptance of a Residual Certificate, each Holder thereof
hereby agrees to accept the plan of complete liquidation adopted by the Trustee
under this Section and to take such other action in connection therewith as may
be reasonably requested by the Trustee.

         Section 7.04      [RESERVED].

                                  ARTICLE VIII

                          RIGHTS OF CERTIFICATEHOLDERS

         Section 8.01      Limitation on Rights of Holders.

         (a) The death or incapacity of any Certificateholder shall not operate
to terminate this Agreement or this Trust Fund, nor entitle such
Certificateholder's legal representatives or heirs to claim an accounting or
take any action or proceeding in any court for a partition or winding up of this
Trust Fund, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them. Except as otherwise expressly provided herein, no
Certificateholder, solely by virtue of its status as a Certificateholder, shall
have any right to vote or in any manner otherwise control the Trustee 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 (or Percentage Interest) of
Certificates of each Class affected thereby 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

<PAGE>

reasonably require, of the names and addresses of the Certificateholders of each
Class as of the most recent Record Date.

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

         (c) Every Holder or Certificate Owner, if the Holder is a Clearing
Agency, by receiving and holding a Certificate, agrees with the Depositor, the
Certificate Registrar and the Trustee that neither the Depositor, 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 Owners, 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. 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, if made in the manner provided
in this Section.

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

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

<PAGE>

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

                                    ARTICLE X

                              REMIC ADMINISTRATION

         Section 10.01     REMIC Administration.

         (a) REMIC elections as set forth in the Preliminary Statement shall be
made 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. The regular interests and residual interest in each
REMIC shall be as designated in the Preliminary Statement.

         (b) The Closing Date is hereby designated as the "Startup Day" of each
REMIC within the meaning of section 86OG(a)(9) of the Code. The latest possible
maturity date for purposes of Treasury Regulation 1.86OG-1(a)(4) will be the
Latest Possible Maturity Date.

         (c) The Trustee shall represent the Trust Fund in any administrative or
judicial proceeding relating to an examination or audit by any governmental
taxing authority with respect thereto. 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 expenses to the extent provided in clause (i) above
from the Distribution Account, provided, however, the Trustee shall not be
entitled to reimbursement for expenses incurred in connection with the
preparation of tax returns and other reports as required by Section 6.19 and
this Section.

         (d) The Trustee shall prepare, sign and file all of each REMIC's
federal and appropriate 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.

         (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

<PAGE>

REMIC Provisions, or other compliance guidance issued by the Internal Revenue
Service or any state or local taxing authority. Among its other duties, if
required by the Code, the REMIC Provisions, or other such guidance, the Trustee
shall provide, upon receipt of additional reasonable compensation, to the
Treasury or other governmental authority such information as is necessary for
the application of any tax relating to the transfer of a Residual Certificate to
any disqualified person or organization pursuant to Treasury Regulation
1.860E-2(a)(5) and any person designated in Section 860E(e)(3) of the Code.

         (f) The Trustee and the Holders of Certificates shall take any action
or cause any REMIC to take any action necessary to create or maintain the status
of any REMIC as a REMIC under the REMIC Provisions and shall assist each other
as necessary to create or maintain such status. Neither the Trustee nor the
Holder of any Residual Certificate shall knowingly 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 has 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, 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 has advised it in writing
that an Adverse REMIC Event could occur; provided, however, that if no Adverse
REMIC Event would occur but such action could result in the imposition of
additional taxes on the Residual Certificateholders, no such Person shall take
any such action, or cause any REMIC to take any such action without the written
consent of the Residual Certificateholders.

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

         (j) The Trustee shall not enter into any arrangement by which any REMIC
will receive a fee or other compensation for services.

<PAGE>

         (k) The Trustee shall treat the Basis Risk Reserve Fund as an outside
reserve fund within the meaning of Treasury Regulation Section 1.860G-2(h) that
is owned by the holders of the Interest-Only Certificates and that is not an
asset of any REMIC. The Trustee shall treat the rights of the Holders of the
LIBOR Certificates to receive distributions from the Basis Risk Reserve Fund to
cover Basis Risk Shortfalls and Unpaid Basis Risk Shortfalls as payments under a
cap contract written by the Holders of the Class X-A-1, Class X-A-2, Class X-B
Certificates in favor of the Holders of the LIBOR Certificates. Thus, each Class
A-1, Class A-2, Class A-R, Class B-1, Class B-2 and Class B-3 Certificate shall
be treated as representing not only ownership of an interest in a REMIC, but
also ownership of an interest in an interest rate cap contract. For purposes of
determining the issue prices of the Certificates, the interest rate cap
contracts shall be assumed to have a zero value unless and until required
otherwise by an applicable taxing authority. Each Holder or beneficial owner of
a LIBOR Certificate or an Interest-Only Certificate agrees, by its acceptance of
such Certificate or a beneficial interest therein, to treat, for tax purposes,
the LIBOR Certificates and Interest-Only Certificates in a manner consistent
with the treatment described in this Section 10.01(k).

         (l) The Class A-R Holder shall act as "tax matters person" with respect
to each REMIC and irrevocably appoints the Trustee to act as its agent in such
roles.

         (m) Neither the Trustee nor the Depositor, as assignees under the
Servicing Agreement, shall provide any consent pursuant to the Servicing
Agreement or knowingly take any action under such Servicing Agreement that would
conflict with or violate the provisions of this Article X.

         Section 10.02     Prohibited Transactions and Activities.

         Neither the Depositor 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 Distribution
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 any such REMIC as a REMIC or of the interests therein other than the
Residual Certificate 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 any such REMIC to be
subject to any tax including a tax on prohibited transactions or prohibited
contributions pursuant to the REMIC Provisions.

         Section 10.03     Indemnification with Respect to Prohibited
                           Transactions or 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

<PAGE>

obligations set forth herein, the Trustee shall indemnify the Certificateholders
of the related 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 Depositor or the Holder of the Residual
Certificate, nor for any such Losses resulting from misinformation provided by
any of the foregoing parties on which the Trustee has relied. 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, the Mortgage Loan Purchase and Sale Agreement or the Servicing
Agreement, (2) for any Losses other than arising out of malfeasance, willful
misconduct or negligent performance by the Trustee of its duties and obligations
set forth herein, and (3) for any special or consequential damages to
Certificateholders of the related Residual Certificate (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 Trustee,
shall not, except to the extent provided in the Servicing Agreement, knowingly
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 Servicer has provided to the Trustee an Opinion of
Counsel concluding that, under the REMIC Provisions, such action would not
adversely affect the status of any REMIC as a REMIC and any income generated for
any REMIC by the REO Property would not result in the imposition of a tax upon
such REMIC.

         (b) The Depositor shall cause the Servicer (to the extent provided in
the Servicing Agreement) to make reasonable efforts to sell any REO Property for
its fair market value. In any event, however, the Depositor shall, or shall
cause the Servicer (to the extent provided in the Servicing Agreement) to,
dispose of any REO Property within three years of its acquisition by the Trust
Fund unless the Depositor or the Servicer (on behalf of the Trust Fund) has
received a grant of extension from the Internal Revenue Service to the effect
that, under the REMIC Provisions and any relevant proposed legislation and under
applicable state law, the REMIC may hold REO Property for a longer period
without adversely affecting the REMIC status of such REMIC or causing the
imposition of a Federal or state tax upon such REMIC. If such an extension has
been received, then the Depositor, acting on behalf of the Trustee hereunder,
shall, or shall cause the 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 such an extension has not
been received and the Depositor or the Servicer, acting on behalf of the Trust
Fund hereunder, is unable to sell the REO Property within 33 months after its
acquisition by the Trust Fund or if such an extension, has been received and the
Depositor or the Servicer is unable to sell the REO Property within the period
ending three months before the close of the Extended Period, the Depositor shall
cause the Servicer, before the end of the three year period or the Extended
Period, as applicable, to (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

<PAGE>

bidder (which may be the 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.

                                   ARTICLE XI

                            MISCELLANEOUS PROVISIONS

         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.

         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
and the Trustee, without notice to or the consent of any of the Holders, (i) to
cure any ambiguity or mistake, (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 or with the provisions of the Servicing Agreement, (iii)
to add any other provisions with respect to matters or questions arising under
this Agreement, (iv) to modify alter, amend, add to or rescind any of the terms
or provisions contained in this Agreement or (v) 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 clauses (iii) or (iv) of such sentence
adversely affect in any material respect the interests of any Holder unless such
Holder has consented thereto. Prior to entering into any amendment without the
consent of Holders pursuant to this paragraph, the Trustee shall be provided
with an Opinion of Counsel (at the expense of the party requesting such
amendment) to the effect that such amendment is permitted under this Section.
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
the then current rating assigned to the Certificates.

         (b) This Agreement may also be amended from time to time by the
Depositor 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

<PAGE>

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 such REMIC; and provided further, that no
such amendment may (i) reduce in any manner the amount of, or delay the timing
of, payments received on Mortgage Loans which are required to be distributed on
any Certificate, without the consent of the Holder of such Certificate or (ii)
reduce the aforesaid percentages of Class Principal Amount or Class Notional
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 (or
Percentage Interest) of each Class of Certificates affected thereby. For
purposes of this paragraph, references to "Holder" or "Holders" shall be deemed
to include, in the case of any Class of Book-Entry Certificates, the related
Certificate Owners.

         (c) Promptly after the execution of any such amendment, the Trustee
shall furnish written notification of the substance of such amendment to each
Holder, the Depositor and 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 the Servicing
Agreement, the Trustee shall not consent to any amendment of the 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 Class Notional Amount (or Percentage Interest), Certificates
owned by the Depositor, the Trustee, the Servicer or any Affiliates thereof are
not to be counted so long as such Certificates are owned by the Depositor, the
Trustee, the Servicer or any Affiliate 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 holder, upon the request of such holder 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.

                  that is exempt from federal income tax unless such
                  organization is subject to the tax on unrelated business
                  income imposed by Code Section 511.

<PAGE>

                  Certificate Registrar, and upon which the Certificate
                  Registrar shall be entitled to rely, to the effect that the
                  purchase and holding of such Residual Certificate by the
                  Investor will not result in the assets of the Trust Fund being
                  deemed to be plan assets and subject to the prohibited
                  transaction provisions of ERISA or the Code or Similar Law,
                  and will not subject the Trustee or the Depositor to any
                  obligation in addition to those undertaken by such entities in
                  the Trust Agreement, which opinion of counsel shall not be an
                  expense of the Trust Fund, the Trustee, the Certificate
                  Registrar or the Depositor.

         5.       That the Purchaser hereby acknowledges that under the terms of

                  Certificates, no transfer of the Residual Certificates shall
                  be permitted to be made to any person unless the Certificate
                  Registrar and Trustee have received a certificate from such
                  transferee containing the representations in paragraphs 3 and
                  4 hereof.

         6.       That the Purchaser does not hold REMIC residual securities as
                  nominee to facilitate the clearance and settlement of such
                  securities through electronic book-entry changes in accounts
                  of participating organizations (such entity, a "Book-Entry
                  Nominee").

         7.       That the Purchaser does not have the intention to impede the
                  assessment or collection of any federal, state or local taxes

                  Certificate.

         8.       That the Purchaser will not transfer a Residual Certificate to
                  any person or entity (i) as to which the Purchaser has actual
                  knowledge that the requirements set forth in paragraph 3,
                  paragraph 6 or paragraph 10 hereof are not satisfied or that
                  the Purchaser has reason to believe does not satisfy the
                  requirements set forth in paragraph 7 hereof, and (ii) without
                  obtaining from the prospective Purchaser an affidavit
                  substantially in this form and providing to the Trustee and
                  the Certificate Registrar a written statement substantially in
                  the form of Exhibit C to the Agreement.

         9.       That the Purchaser understands that, as the holder of a
                  Residual Certificate, the Purchaser may incur tax liabilities
                  in excess of any cash flows generated by the interest and that
                  it intends to pay taxes associated with holding such Residual

         11.      The Purchaser will not cause income from the Residual
                  Certificate to be attributable to a foreign permanent
                  establishment or fixed base (within the meaning of an
                  applicable income tax treaty) of the Purchaser or another U.S.

affidavit of _____________________________ (the "Transferee"), and has no actual
knowledge that such affidavit is not true and has no reason to believe that the
information contained in paragraph 7 thereof is not true, and has no reason to

significant evidence to indicate that the Transferee will not continue to pay
its debts as they become due.

Lynch Mortgage Investors, Inc. (the "Depositor"), we confirm that:

(1)      We understand that the Privately Offered Certificates have not been,
         and will not be, registered under the Securities Act of 1933, as
         amended (the "Securities Act"), and may not be sold except as permitted
         in the following sentence. We agree, on our own behalf and on behalf of
         any accounts for which we are acting as hereinafter stated, that if we
         should sell any Privately Offered Certificates within two years of the
         later of the date of original issuance of the Privately Offered
         Certificates or the last day on which such Privately Offered
         Certificates are owned by the Depositor or any affiliate of the
         Depositor 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 Certificate Registrar under the Trust Agreement, dated
         as of March 1, 2003, by and between Merrill Lynch Mortgage Investors,

         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 Certificate Registrar 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.

Custodian additional documents, original or otherwise, evidencing an assumption
or modification of a Mortgage Loan which documents shall become part of the
Custodian's Mortgage File.

         3.       Obligations of the Custodian.

         (a)      With respect to each Custodian's Mortgage File, the Custodian
is exclusively the custodian for the Registered Holder from and after the
related Delivery Date. The Custodian shall hold all documents constituting the
Custodian's Mortgage File received by it for the exclusive use and benefit of
the Registered Holder, and shall make disposition thereof only in accordance
with this Agreement and the instructions furnished by the Registered Holder. The
Custodian shall segregate and maintain continuous custody of all documents
constituting the Custodian's Mortgage File received by it in secure and
fire-resistant facilities in accordance with customary standards for such
custody. The Custodian represents and warrants that it will verify the receipt
of required documents, the accuracy of certain information, and indicate
discrepancies pursuant to the custody receipt requirements herein. The Custodian
makes no representations or warranties as to, and shall not be responsible to,
verify: (i) the validity, legality, enforceability, sufficiency, recordability,
due authorization or genuineness of any of the documents contained in each
Custodian's Mortgage File or any of the Mortgage Loans or (ii) the
collectability, insurability, effectiveness or suitability of any such Mortgage
Loan. No provision of this Agreement shall be construed to impose on the
Custodian any obligation of a third party seller under this Agreement or a
Purchase Agreement under any circumstances.

         (b)      The Custodian shall, at its own expense, maintain at all times
during the existence of this Agreement and keep in full force and effect a
fidelity bond, errors and omissions insurance, theft and documents insurance and
forgery insurance in amounts and with standard coverage as is customary for
insurance typically maintained by institutions that act as custodians. The
minimum coverage under any such bond and insurance policies shall be at least
equal to the corresponding amounts required by the Government National Mortgage
Association, Fannie Mae or Freddie Mac either of the Custodian or in their
respective Seller/Servicing Guides. A certificate of an authorized officer for
the Custodian shall be furnished to the Registered Holder upon request as
evidence of its compliance with any such requirement.

         4.       Custody Receipts.

         (a)      Initial Custody Receipt. The Custodian shall review the
documents delivered to it on each Delivery Date and shall deliver to MLCC as
initial Registered Holder within two (2) Business Days following the Delivery
Date, or within a mutually agreed upon time between the Bank and the Custodian,
but prior to the Closing Date, an Initial Custody Receipt with respect to the
Mortgage Loans, in which the Custodian shall certify that such Mortgage Loans
are held for MLCC (as Registered Holder) and that, as to each Mortgage Loan
listed in the Mortgage Loan Schedule (other than any Mortgage Loan paid in full
or any Mortgage Loan specifically identified in such certification as not
covered by such certification), (a) all documents described in Paragraphs 2(a)
through 2(e) and to the extent provided in the Custodian's Mortgage Files
Paragraphs 2(f) through 2(j), if applicable, of this Agreement are in its
possession and (b) each Mortgage Note has been endorsed and each Assignment has
been executed as provided in

                                      O-7

<PAGE>

Paragraph 2 hereof. If the Custodian determines from such verification that any
discrepancy or deficiency exists with respect to a Custodian's Mortgage File,
the Custodian shall note such discrepancy on the schedule of exceptions attached
to the Initial Custody Receipt as Schedule B thereto (the "Exception Report").

         The Custodian shall also note on the Exception Report, with respect to
each Mortgage Loan, whether a certified copy of the related Mortgage was
delivered to the Custodian in lieu of the original of such Mortgage, whether a
certified copy of an intervening assignment of the related Mortgage was
delivered to the Custodian in lieu of the original of such assignment, and
whether a preliminary title report with respect to such Mortgage Loan was
delivered to the Custodian in lieu of the original policy of title insurance.

         On the first Business Day of each calendar month following delivery of
the Initial Custody Receipt until the month in which the Final Custody Receipt
is to be delivered pursuant to Subsection (b) below, the Custodian shall deliver
to the Registered Holder of the Initial Custody Receipt, an updated Exception
Report, revised to reflect any changes with respect to the status of the
exceptions noted for the related Mortgage Loans.

         (b)      Final Custody Receipt. Not later than sixty (60) days
following the date of each delivery of an Initial Custody Receipt, the Custodian
shall deliver to the Registered Holder of the Initial Custody Receipt the Final
Custody Receipt, with respect to the Mortgage Loans related to such Initial
Custody Receipt, in which the Custodian shall certify to the Registered Holder
that, as to each Mortgage Loan listed in the related Mortgage Loan Schedule
(other than any Mortgage Loan paid in full or any Mortgage Loan specifically
identified in such certification as not covered by such certification), (a) all
documents described in Paragraphs 2(a) through 2(e), and to the extent provided
in the Custodian's Mortgage Files Paragraphs 2(f) through 2(j), if applicable,
of this Agreement are in its possession, (b) such documents have been reviewed
by it and appear regular on their face and relate to such Mortgage Loan, (c)
based on its examination and only as to the foregoing documents, the information
set forth in items (i), (ii), (iii) excluding the zip code requirement, (iv),
(vi), (vii), (viii) and (x) of the definition of "Mortgage Loan Schedule"
respecting such Mortgage Loan is correct, and which as to items (iv), (vi),
(viii), and (x) for adjustable rate Mortgage Loans may reflect interest rates or
amounts that as of the Cutoff Date vary from those provided in the Mortgage Loan
Documents and (d) each Mortgage Note has been endorsed and each Assignment has
been executed as provided in Paragraph 2 hereof. If the Custodian determines
from such verification that any discrepancy or deficiency exists with respect to
a Custodian's Mortgage File, the Custodian shall note such discrepancy on the
Exception Report attached to the Final Custody Receipt as Schedule B thereto.
The Custodian shall also note on such Exception Report, with respect to each
Mortgage Loan, whether a certified copy of the related Mortgage was delivered to
the Custodian in lieu of the original of such Mortgage, whether a certified copy
of an intervening assignment of the related Mortgage was delivered to the
Custodian in lieu of the original of such assignment, and whether a preliminary
title report with respect to such Mortgage Loan was delivered to the Custodian
in lieu of the original policy of title insurance. Except as specifically
provided above, the Custodian shall be under no duty to review, inspect or
examine such documents to determine that any of them are enforceable or
appropriate for their prescribed purpose. Upon delivery of the Final

                                      O-8

<PAGE>

Custody Receipt to the Registered Holder of the Initial Custody Receipt, the
Initial Custody Receipt shall be of no further force or effect.

         (c)      Within five (5) days of receipt of written directions, in the
form attached hereto as Exhibit Six, from the Registered Holder with respect to
all or a portion of the Mortgage Loans owned by such Registered Holder, and upon
the prior tender by such Registered Holder of the applicable Initial and/or
Final Custody Receipt(s), as applicable, the Custodian shall deliver all or any
portion of the Custodian's Mortgage Files held by it to the Registered Holder,
or to such other party as the Registered Holder may direct, as provided in
Paragraph 19, at the place indicated in any such written direction from the
Registered Holder and shall deliver to the Registered Holder a new Initial or
Final Custody Receipt, as applicable, with respect to the Custodian's Mortgage
Files retained by the Custodian. The Registered Holder may require the Custodian
to complete the endorsements on any Mortgage Notes in its possession and to
complete the Assignment of Mortgages prepared by the Servicer in blank, within a
reasonable period of time. The cost of this shall be reimbursed by the
Registered Holder. A list of authorized signatures for such written directions
has been furnished to the Custodian by the Registered Holder pursuant to
Paragraph 20 hereof. Upon the Custodian's receipt of such written notification
from the Registered Holder that the Registered Holder has sold any or all of the
Mortgage Loans, which notification shall be accompanied by the Initial and/or
Final Custody Receipt(s), as applicable that relate to such Mortgage Loans, the
Custodian shall change its records to reflect that such purchaser is the owner
of such Mortgage Loans and shall immediately, upon the direction of such
Registered Holder, either deliver the related Custodian's Mortgage Files to such
purchaser at the expense of such purchaser or issue an Initial or Final Custody
Receipt in the name of such purchaser. Such purchaser, as a Registered Holder,
shall be required to simultaneously furnish to the Custodian a list of
authorized signatures for written directions pursuant to Paragraph 20 hereof.
The Custodian shall then deliver to the Registered Holder a new Initial and/or
Final Custody Receipt, as applicable reflecting all Mortgage Loans with respect
to which the Custodian still holds the related Custodian's Mortgage Files on
behalf of the Registered Holder. The Registered Holder and the Custodian agree
herein that any purchaser of any or all of the Mortgage Loans shall succeed to
the rights and obligations of the Registered Holder under this Agreement with
respect to such Mortgage Loans upon receipt of the related Initial and/or Final
Custody Receipt, as applicable subject to the provisions of Paragraph 15 hereof.

         5.       Fees and Expenses of the Custodian.

         It is understood that the Custodian will charge such fees for its
services under this Agreement as are set forth in a separate agreement between
the Custodian and MLCC, the payment of which, together with the Custodian's
expenses in connection herewith, shall be solely the obligation of the
Registered Holder with respect to the related Mortgage Loans.

successor Custodian thereafter appointed, as to such

or to a successor Custodian appointed by such Registered Holder at the expense

records and other papers in the possession of or under the control of the
Custodian relating to any or all of the Mortgage Loans for which the Custodian

expense of the inspecting party.

         8.       Counterparts.

         For the purpose of facilitating the execution of this Agreement as
herein provided and for other purposes, this Agreement may be executed

Agreement. Such list may be in the form of a copy of the Mortgage Loan Schedule

         15.      Assignment of Agreement.

         The Registered Holder with respect to all or a portion of the Mortgage
Loans owned by such Registered Holder shall have the right to assign, in whole
or in part, its interests under this Agreement with respect to some or all of
the Mortgage Loans, and to designate any person or exercise any rights of the
Registered Holder hereunder, and such assignee or designee shall accede to the
rights and obligations hereunder of the Registered Holder with respect to such
Mortgage Loans. All references to the Registered Holder shall be deemed to
include its assignee or designee. In connection with any such assignment, the
Registered Holder with respect to all or a portion of the Mortgage Loans owned
by such Registered Holder may require that arrangements reasonably satisfactory
to it be made for the exchange of previously executed and outstanding Custody
Receipt(s) for a Custody Receipt representing such assignment. The Custodian may
not assign its interests or delegate its duties under this Agreement without the
prior written consent of the Registered Holder. In the event of any such
assignment or delegation, the Registered Holder shall not be responsible for any
fees of the successor Custodian in excess of the fees formerly paid by the
Registered Holder to the Custodian.

         16.      Notice.

         (a)      All demands, notices and communications hereunder shall be in
writing and shall be sent to the other party at the address shown on the first
page hereof, or such other address as may hereafter be furnished to the other
party by written notice given to the other party hereto in a notice complying
with the terms and provisions of this Section 16 or on an Exhibit Six notice
provided pursuant to Section 4(c).

         (b)      Any such demand, notice or communication hereunder shall be
deemed conclusively to have been given if personally delivered at or mailed by
registered mail, postage prepaid, and return receipt requested or transmitted by
telex, telegraph or facsimile transmission and by a similar writing to the other
party at its address as described in Subclause (a).

         17.      Indemnification.

         (a)      Neither the Custodian nor any of its directors, officers,
agents or employees, shall be liable for any action taken or omitted to be taken
by it or them hereunder or in connection herewith in good faith and believed by
it or them to be within the purview of this Agreement, except for its or their
own negligence, lack of good faith or willful misconduct.

         (b)      The Registered Holder and the Custodian agree to indemnify and
hold each other and their respective directors, officers, agents and employees
harmless against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever, including reasonable attorney's fees, that may be
imposed on, incurred by, or asserted against it or them in any action taken or
not taken by it or them hereunder. This indemnification shall include, but not
be limited to, the claims of third parties arising from or related to this
Agreement or the Mortgage Loans. This indemnification applies if such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses, disbursements, or claims were imposed on, incurred by or
asserted against the party seeking indemnification because of the breach of the
obligations, negligence, lack of good faith

                                      O-12

<PAGE>

or willful misconduct of the other party or any of its directors, officers,
agents or employees. The foregoing indemnification shall survive any termination
of this Agreement and the resignation or removal of the Custodian.

         (c)      In the event that the Custodian fails to produce a Mortgage
Note, Assignment of Mortgage or any other document related to a Mortgage Loan
that was in its possession pursuant to Section 2 within four (4) Business Days
after required or requested by the Registered Holder or its Servicer (a
"Custodial Delivery Failure"), and provided that (i) Custodian previously
delivered to the Registered Holder an Initial Custody Receipt which did not list
such document as an exception; (ii) such document is not outstanding pursuant to
a request for release in the form annexed hereto as Exhibit Five; and (iii) such
document was held by the Custodian on behalf of the Registered Holder, then the
Custodian shall: (a) with respect to any missing Mortgage Note, promptly deliver
to the Registered Holder upon request, a Lost Note Affidavit in the form of
Exhibit Seven hereto and (b) with respect to any missing document related to
such Mortgage Loan, including but not limited to a missing Mortgage Note, (1)
indemnify the Registered Holder, and its successor in interest, in accordance
with the succeeding paragraph and, (2) obtain and maintain an insurance bond in
the name of the Registered Holder, and its successors in interest and assigns,
insuring against any losses associated with the loss of such document, in an
amount equal to the then outstanding principal balance of the related Mortgage
Loan or such lesser amount requested by the Registered Holder, at the Registered
Holder's sole option, at any time the long term obligations of the Custodian are
rated below the second highest rating category of Moody's Investors Service,
Inc. or Standard and Poor's Ratings Group, a division of McGraw-Hill, Inc.

         (d)      The Custodian agrees to indemnify and hold the Registered
Holder, and its designees, harmless against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever, including reasonable
attorney's fees, that may be imposed on, incurred by, or asserted against it or
them in any way relating to or arising out of a Custodial Delivery Failure, as
defined herein, or the Custodian's negligence, lack of good faith or willful
misconduct. The forgoing indemnification shall survive any termination or
assignment of this Agreement.

         18.      Reliance of Custodian.

         In the absence of bad faith on the part of the Custodian, the Custodian
may conclusively rely, as to the truth of the statements and the correctness of
the opinions expressed therein, upon any request, instructions, certificate,
opinion or other document furnished to the Custodian, reasonably believed by
Custodian to be genuine and to have been signed or presented by the proper party
or parties and conforming to the requirements of this Agreement. No
representations, warranties, covenants or obligations of the Custodian shall be
implied with respect to this Agreement or the Custodian's services hereunder.

         19.      Transmission of Custodian's Mortgage File.

         Written instructions as to the method of shipment and shipper(s)
Custodian is directed to utilize in connection with transmission of mortgage
files and loan documents in the performance of the Custodian's duties hereunder
shall be delivered by the Registered Holder (the "Requesting

                                      O-13

<PAGE>

Party") with respect to all or a portion of the Mortgage Loans owned by such
Registered Holder to the Custodian prior to any shipment of any mortgage files
and loan documents hereunder. The Registered Holder will arrange for the
provision of such services at its sole cost and expense (or, at Custodian's
option, reimburse Custodian for all costs and expenses incurred by Custodian
consistent with such instructions) and will maintain such insurance against loss
or damage to mortgage files and loan documents as the Requesting Party deems
appropriate. Without limiting the generality of the provisions of Paragraph 17
above, it is expressly agreed that in no event shall the Custodian have any
liability for any losses or damages to any person, including, without
limitation, the Requesting Party, arising out of actions of the Custodian
consistent with instructions of the Requesting Party. In the absence of any
written instructions with respect to the transmission of the Custodian's
Mortgage Files, the parties hereby agree that the Custodian may utilize any
nationally recognized overnight courier service and shall be entitled to
reimbursement from the Registered Holder.

         20.      Authorized Representative.

         Unless the Registered Holder shall have given the Custodian written
notice to the contrary, each individual designated as an authorized
representative of the Registered Holder with respect to all or a portion of the
Mortgage Loans owned by such Registered Holder, and the Custodian, respectively
(an "Authorized Representative"), is authorized to give and receive notices,
requests and instructions and to deliver certificates and documents in
connection with this Agreement on behalf of the Registered Holder with respect
to all or a portion of the Mortgage Loans owned by such Registered Holder, or
the Custodian, as the case may be, and the specimen signature for each such
Authorized Representative of MLCC as the initial Registered Holder and each such
Authorized Representative of the Custodian initially authorized hereunder is set
forth on Exhibit Three and Exhibit Four hereof, respectively. Any subsequent
Registered Holder of the Mortgage Loans shall provide the Custodian specimen
signatures for each Authorized Representative of such Registered Holder. From
time to time, the Registered Holder and the Custodian may, by delivering to the
other party a revised exhibit, change the information previously given pursuant
to this Paragraph, but each of the parties hereto shall be entitled to rely
conclusively on the then current exhibit until receipt of a superseding exhibit.

         21.      Release of Custodian's File for Servicing.

         Upon written request by the Registered Holder or its Servicer with
respect to all or a portion of the Mortgage Loans owned by such Registered
Holder, pursuant to the form attached hereto as Exhibit Five, the Custodian
shall use its best efforts to promptly, and in no event no later than two (2)
Business Days after receipt of such written request completed in accordance with
this Agreement, release to the Registered Holder or its Servicer for the
servicing or foreclosure of any of the Mortgage Loans the related Custodian's
Mortgage File. All Custodian's Mortgage Files so released to the Registered
Holder's Servicer shall be held by such Servicer in trust for the benefit of the
Registered Holder in accordance with the provisions of a servicing agreement
entered into between the Registered Holder and such Servicer. The Registered
Holder or its Servicer shall return to the Custodian the Custodian's Mortgage
File that has been released to the Registered Holder or its Servicer, when the
Registered Holder's or its Servicer's need therefor in connection with such
servicing or foreclosure no longer exists, unless the Mortgage

                                      O-14

<PAGE>

Loan shall be liquidated, in which case, upon receipt of a certification to this
effect from the Registered Holder or its Servicer to the Custodian in the form
annexed hereto as Exhibit Five, and the Custodian shall thereupon reflect any
such liquidation on the list of Mortgage Loans maintained by it pursuant to
Paragraph 9 of this Agreement.

         Custodian shall not release more than 5% of the number of Mortgage
Loans at any time without additional written consent from Registered Holder.
This limitation shall not apply to the release of Custodial Files upon payment
in full.

         22.      Release of Custodian's Mortgage File for Payment.

         Upon the repurchase or substitution of any Mortgage Loan pursuant to a
Purchase Agreement or the payment in full of any Mortgage Loan, which shall be
evidenced by the Custodian's receipt of a request for release, receipt and
certification in the form annexed hereto as Exhibit Five (which certification
shall include a statement to the effect that all amounts received in connection
with such payment or repurchase have been credited to the account of the
Registered Holder), the Custodian shall use its best efforts promptly and in no
event later than two (2) Business Days after receipt of the written request
therefor completed in accordance with this Agreement, release the related
Custodian's Mortgage File to the Registered Holder or, at the request of the
Registered Holder, its Servicer, such repurchase thereupon to be noted on the
list maintained by the Custodian pursuant to Paragraph 9 of this Agreement.

         23.      Reproduction of Documents.

         This Agreement and all documents relating thereto, including, without
limitation, (a) consents, waivers and modifications that may hereafter be
executed, and (b) certificates and other information previously or hereafter
furnished, may be reproduced by any photographic, photostatic, microfilm,
microcard, miniature photographic or other similar process. The parties agree
that any such reproduction shall be admissible in evidence as the original
itself in any judicial or administrative proceeding, whether or not the original
is in existence and whether or not such reproduction was made by a party in the
regular course of business, and that any enlargement, facsimile or further
reproduction of such reproduction shall likewise be admissible in evidence.

         24.      Severability.

         If any one or more of the covenants, agreements, provisions or terms of
this Agreement shall be for any reason whatsoever held invalid, the invalidity
of any such covenant, agreement, provision or term of this Agreement shall in no
way affect the validity or enforceability of the other provisions of this
Agreement; provided, however, that if the invalidity of any covenant, agreement
or provision shall deprive any party of the economic benefit intended to be
conferred by this Agreement, the parties shall negotiate in good faith to
develop a structure the economic effect of which is as nearly as possible the
same as the economic effect of this Agreement.

         Custodian represents and warrants to and covenants with MLCC as
follows:

         (a)      Custodian is a corporation duly incorporated, validly existing
                  and in good standing under the laws of Minnesota.

         (b)      Custodian has full corporate power to execute, deliver and
                  perform the obligations under this Agreement. MLCC may rely on

                  additional consent, authorization, or regulatory filing is
                  required in order for Custodian to legally perform its
                  obligations.

         (c)      This agreement constitutes a legal, valid and binding
                  obligation of Custodian, enforceable against Custodian in
                  accordance with the terms herein except as limited by
                  bankruptcy, insolvency, liquidation or other similar laws
                  affecting generally the enforcement of creditor's rights.

         IN WITNESS WHEREOF, the Custodian and MLCC have caused this Agreement

                                    RECITALS

                  WHEREAS, MLCC may from time to time, purchase certain Mortgage
Loans from third party sellers pursuant to the terms and condition of certain
mortgage loan purchase agreements entered into between MLCC and such parties
(each, a "Purchase Agreement");

                  WHEREAS, pursuant to the Custodial Agreement, the Custodian
has agreed to take possession of mortgage notes evidencing Mortgage Loans and
certain other Mortgage Loan Documents delivered from time to time pursuant to
the Custodial Agreement;

                  WHEREAS, MLCC and the Custodian have agreed, subject to the
terms and conditions of this Amendment, that the Custodial Agreement be amended
to reflect the replacement of individual certifications with a Master Trust
Receipt; and

                  Accordingly, MLCC and Custodian hereby agree, in consideration
of the mutual promises and mutual obligations set forth herein, that the
Custodial Agreement is hereby amended as follows:

         SECTION 1.        Definitions:

         (a) Section 1 of the Custodial Agreement is hereby amended by deleting
             the definitions of "Custody Receipt", "Final Custody Receipt" and

         (b) Section 1 of the Custodial Agreement is hereby amended by inserting
             the following definition into its proper alphabetical order:

                                      P-1

<PAGE>

         Schedule and attached thereto as Schedule B, as updated from time to
         time in accordance with Section 4 hereof.

         SECTION 2.        Trust Receipt. Section 4 is hereby deleted in its
entirety and replaced in its entirety with the following:

         (a)      The Custodian shall review the documents delivered to it on
             each Delivery Date and shall deliver to Registered Holder within
             the time frames outlined in exhibit B to this amenedment, but prior
             to Closing Date, a Mortgage Loan Schedule and Exception Report with
             respect to the Mortgage Loans, and the delivery of each Mortgage
             Loan Schedule and Exception Report by the Custodian hereunder shall
             be the Custodian's certification that such Mortgage Loans are held
             for MLCC (as Registered Holder) and that, as to each Mortgage Loan
             listed in the related Mortgage Loan Schedule (other than any
             Mortgage Loan paid in full or any Mortgage Loan specifically
             identified in such certification as not covered by the Exception
             Report), (a) all documents described in Paragraphs 2(a) through
             2(e) and to the extent provided in the Custodian's Mortgage Files
             Paragraphs 2(f) through 2(j), if applicable, of this Agreement are
             in its possession, (b) such documents have reviewed by it and
             appear regular on their face and relate to such Mortgage Loan, (c)
             based on its examination and only as to the foregoing documents,
             the information set forth in terms (i), (ii), (iii) excluding the
             zip code requirement, (iv), (vi), (vii), (viii) and (x) of the
             definition of "Mortgage Loan Schedule" respecting such Mortgage
             Loan is correct, and which as to items (iv) (vi), (viii) and (x)
             for adjustable rate Mortgage Loan Documents and (d) each Mortgage
             Note has been endorsed and each Assignment has been executed as
             provided in Paragraph 2 hereof. The Custodian shall determine
             whether any discrepancy or deficiency exists with respect to a
             Custodian's Mortgage File and shall note such discrepancy on the
             Exception Report. The Custodian shall also note on such Exception
             Report, with respect to each Mortgage Loan, whether a certified
             copy of the related Mortgage was delivered to the Custodian in lieu
             of the original of such Mortgage, whether a certified copy of an
             intervening assignment of the related Mortgage was delivered to the
             Custodian in lieu of the original of such assignment, and whether a
             preliminary title report with respect to such Mortgage Loan was
             delivered to the Custodian in lieu of the original policy of title
             insurance. Except as specifically provided above, the Custodian
             shall be under no duty to review, inspect or examine such documents
             to determine that any of them are enforceable or appropriate for
             their prescribed purpose.

         (b)      On the date of this Amendment, the Custodian shall deliver to
             MLCC, a Trust Receipt with a Mortgage Loan Schedule and Exception
             Report attached thereto reflecting all Mortgage Loans subject to
             the Custodial Agreement as of such date.

         (c)      Each Mortgage Loan Schedule and Exception Report delivered by
             the Custodian to MLCC shall supersede and cancel the Mortgage Loan
             Schedule and Exception Report previously delivered by the Custodian
             to MLCC hereunder, and shall replace the then existing Mortgage
             Loan Schedule and Exception Report to be attached to the Trust
             Receipt. Notwithstanding anything to the contrary set forth herein,
             in the event that the Mortgage Loan Schedule and Exception Report
             attached to the Trust Receipt

                                      P-2

<PAGE>

             is different from the most recently delivered Mortgage Loan
             Schedule and Exception Report, then the most recently delivered
             Mortgage Loan Schedule and Exception Report shall control and be
             binding upon the parties hereto.

         (d)      The Custodian shall deliver to MLCC, electronically a Mortgage
             Loan Schedule and Exception Report reflecting any additional
             Mortgage Loans received and reviewed in accordance with the
             procedures set forth in Section 2(a) hereof.

         (e)      Within five (5) days of receipt of written directions, in the
             form attached hereto as Exhibit Six, from the Registered Holder
             with respect to all or a portion of the Mortgage Loans owned by
             such Registered Holder, the Custodian shall deliver all or any
             portion of the Custodian's Mortgage Files held by it to Registered
             Holder, or to such other party as the Registered Party may direct,
             as provided in Paragraph 19, at the place indicated in any such
             written direction from the Registered Holder and shall deliver to
             the Registered Holder a new Mortgage Loan Schedule and Exception
             Report, with respect to the Custodian's Mortgage Files retained by
             the Custodian. The Registered Holder may require the Custodian to
             complete the endorsements on any Mortgage Notes in its possession
             and to complete the Assignment of Mortgages prepared by the
             Servicer in blank, within a reasonable period of time. The cost of
             this shall be reimbursed by the Registered Holder. A list of
             authorized signatures for such written directions has been
             furnished to the Custodian by the Registered Holder pursuant to
             Paragraph 20 hereof. Upon the Custodian's receipt of such written
             notification from the Registered Holder that the Registered Holder
             has sold any or all of the Mortgage Loans, which notification shall
             be accompanied by a Mortgage Loan Schedule identifying such
             Mortgage Loans, the Custodian shall change its records to reflect
             that such purchaser is the owner of such Mortgage Loans and shall
             immediately, upon the direction of such Registered Holder, either
             deliver the related Custodian's Mortgage Files to such purchaser at
             the expense of such purchaser or issue a Mortgage Loan Schedule and
             Exception Report in the name of such purchaser. Such purchaser, as
             a Registered Holder, shall be required to simultaneously furnish to
             the Custodian a list of authorized signatures for written

<PAGE>

                                   SCHEDULE B

                  MORTGAGE LOAN REPRESENTATIONS AND WARRANTIES
                                  OF THE SELLER

         The Seller hereby represents and warrants to the Purchaser, as to each
Mortgage Loan, as of the Closing Date as follows:

         (a) The information set forth in the Mortgage Loan Schedule is true and
correct in all material respects as of the Cut-off Date;

         (b) As of the related Closing Date, the Mortgage Loan is not delinquent
in payment more than 30 days and the Mortgage Loan has not been dishonored;
there are no material defaults under the terms of the Mortgage Loan; the Seller
has not advanced funds, or induced, solicited or knowingly received any advance
of funds from a party other than the owner of the Mortgaged Property subject to
the Mortgage, directly or indirectly, for the payment of any amount required by
the Mortgage Loan;

         (c) To the best of the Seller's knowledge, with respect to those
Mortgage Loans as to which the Mortgagors are required to deposit funds into an
escrow account for payment of taxes, assessments, insurance premiums and similar
items as they become due, there are no delinquent taxes, ground rents, water
charges, sewer rents, assessments or other outstanding charges which constitute
a lien on the related Mortgaged Property, and all escrow deposits have been
collected, are under the control of the Servicer, and have been applied to the
payment of such items in a timely fashion, in accordance with such Mortgage. No
escrow deposits or escrow payments or other charges or payments due the Servicer
have been capitalized under the related Mortgage or Mortgage Note. With respect
to those Mortgage Loans for which escrow deposits are not required, to the best
of the Seller's knowledge, there are no delinquent taxes or other outstanding
charges affecting the related Mortgaged Property which constitute a lien on the
related Mortgaged Property;

         (d) The terms of the Mortgage Note and the Mortgage have not been
impaired, waived, altered or modified in any respect, except by written
instruments contained in the Mortgage File, approved, if necessary, by the
insurer under any Primary Mortgage Insurance Policy and recorded in all places
necessary to maintain the first priority of the lien, the substance of which
waiver, alteration or modification is reflected on the Mortgage Loan Schedule.
No Mortgagor has been released, in whole or in part, except in connection with
an assumption agreement which assumption agreement is part of the Mortgage File
and the terms of which are reflected in the Mortgage Loan Schedule;

         (e) Neither the Mortgage Note nor the Mortgage is subject to any right
of rescission, set-off, counterclaim or defense, including the defense of usury,
nor will the operation of any of the terms of the Mortgage Note and the
Mortgage, or the exercise of any right thereunder, render the Mortgage
unenforceable, in whole or in part, or subject to any right of rescission,
set-off, counterclaim or defense, including the defense of usury and to the best
of the Seller's knowledge, no such right of rescission, set-off, counterclaim or
defense has been asserted by any Person with respect thereto;

                                  Schedule B-1

<PAGE>

         (f) All buildings upon the Mortgaged Property are required to be
insured by a generally acceptable insurer against loss by fire, hazards of
extended coverage and such other hazards as are customarily included in extended
coverage in the area where the Mortgaged Property is located, pursuant to
standard hazard insurance policies in an amount which is equal to the lesser of
(A) the replacement cost of the improvements securing such Mortgage Loan or (B)
the principal balance owing on such Mortgage Loan. To the best knowledge of the
Seller, all such standard hazard policies are in effect. On the date of
origination, such standard hazard policies contained a standard mortgagee clause
naming the Seller or the Originator of the Mortgage Loan and their respective
successors in interest as mortgagee and, to the best knowledge of the Seller,
such clause is still in effect and, to the best of the Seller's knowledge, all
premiums due thereon have been paid. If the Mortgaged Property is located in an
area identified by the Federal Emergency Management Agency as having special
flood hazards under the National Flood Insurance Act of 1994, as amended, such
Mortgaged Property is covered by flood insurance in the amount required under
the National Flood Insurance Act of 1994. The Mortgage obligates the Mortgagor
thereunder to maintain all such insurance at Mortgagor's cost and expense, and
on the Mortgagor's failure to do so, authorizes the holder of the Mortgage to
maintain such insurance at Mortgagor's cost and expense and to seek
reimbursement therefor from the Mortgagor;

         (g) To the best of the Seller's knowledge, at the time of origination
of such Mortgage Loan and thereafter, all requirements of any federal, state or
local law including, without limitation, usury, truth-in-lending, real estate
settlement procedures, consumer credit protection, equal credit opportunity or
disclosure laws required to be complied with by the Seller as the Originator of
the Mortgage Loan and applicable to the Mortgage Loan have been complied with in
all material respects;

         (h) The Mortgage has not been satisfied as of the Closing Date,
canceled or subordinated, in whole, or rescinded, and the Mortgaged Property has
not been released from the lien of the Mortgage, in whole or in part (except for
a release that does not materially impair the security of the Mortgage Loan or a
release the effect of which is reflected in the Loan-to-Value Ratio for the
Mortgage Loan as set forth in the Mortgage Loan Schedule), nor to the best of
the Seller's knowledge has any instrument been executed that would effect any
such release, cancellation, subordination or rescission;

         (i) Ownership of the Mortgaged Property is held in fee simple or a
leasehold estate. With respect to Mortgage Loans that are secured by a leasehold
estate, (i) the lease is valid, in full force and effect, and conforms to all of
FNMA's requirements for leasehold estates; (ii) all rents and other payments due
under the lease have been paid; (iii) the lessee is not in default under any
provision of the lease; (iv) the term of the lease exceeds the maturity date of
the related Mortgage Loan by at least five (5) years; and (v) the terms of the
lease provide a Mortgagee with an opportunity to cure any defaults. Except as
permitted by the fourth sentence of this paragraph (i), the Mortgage is a valid,
subsisting and enforceable first lien on the Mortgaged Property, including all
buildings on the Mortgaged Property and all installations and mechanical,
electrical, plumbing, heating and air conditioning systems affixed to such
buildings, and all additions, alterations and replacements made at any time with
respect to the foregoing securing the Mortgage Note's original principal
balance. The Mortgage and the Mortgage Note do not contain any evidence on their
face of any security interest or other interest or right thereto.

                                  Schedule B-2

<PAGE>

Such lien is free and clear of all adverse claims, liens and encumbrances having
priority over the first lien of the Mortgage subject only to (1) the lien of
non-delinquent current real property taxes and assessments not yet due and
payable, (2) covenants, conditions and restrictions, rights of way, easements
and other matters of the public record as of the date of recording which are
acceptable to mortgage lending institutions generally, or which are specifically
referred to in the lender's title insurance policy delivered to the Originator
of the Mortgage Loan and either (A) which are referred to or otherwise
considered in the appraisal made for the Originator of the Mortgage Loan, or (B)
which do not in the aggregate adversely affect the appraised value of the
Mortgaged Property as set forth in such appraisal, and (3) other matters to
which like properties are commonly subject which do not in the aggregate
materially interfere with the benefits of the security intended to be provided
by the Mortgage or the use, enjoyment, value or marketability of the related
Mortgaged Property. Any security agreement, chattel mortgage or equivalent
document related to and delivered in connection with the Mortgage Loan
establishes and creates a valid, subsisting and enforceable first lien and first
priority security interest on the property described therein. With respect to
each Co-op Loan, the security instruments create a valid, enforceable and
subsisting first priority security interest in the Co-op Lease and Co-op Stock
securing the related Mortgage Note subject to only to (a) the lien of the
related cooperative for unpaid assessments representing the Mortgagor's pro rata
share of payments for a blanket mortgage, if any, current and future real
property taxes, insurance premiums, maintenance fees and other assessments to
which like collateral is commonly subject, and (b) other matters to which the
collateral is commonly subject which do not materially interfere with the
benefits of the security intended to be provided; provided, however, that the
related Co-op Loan may be subordinated or otherwise subject to the lien of a
Mortgage on the cooperative building;

         (j) The Mortgage Note is not subject to a third party's security
interest or other rights or interest therein;

         (k) The Mortgage Note and the related Mortgage are genuine and each is
the legal, valid and binding obligation of the maker thereof, enforceable in
accordance with its terms subject to bankruptcy, insolvency and other laws of
general application affecting the rights of creditors. All parties to the
Mortgage Note and the Mortgage had the legal capacity to enter into the Mortgage
Loan and to execute and deliver the Mortgage Note and the Mortgage. The Mortgage
Note and the Mortgage have been duly and properly executed by such parties. The
proceeds of the Mortgage Loan have been fully disbursed and there is no
requirement for future advances thereunder, and any and all requirements as to
completion of any on-site or off-site improvements and as to disbursements of
any escrow funds therefor have been complied with;

         (l) Seller has good title to, and the full right to transfer and sell,
the Mortgage Loan free and clear of any encumbrance, equity, lien, pledge,
charge, claim or security interest, including, to the best knowledge of the
Seller, any lien, claim or other interest arising by operation of law;

         (m) To the best of the Seller's knowledge, each Mortgage Loan is
covered by an ALTA lender's title insurance policy or other generally acceptable
form of policy or insurance acceptable to FNMA or FHLMC, issued by a title
insurer acceptable to FNMA or FHLMC and qualified to do business in the
jurisdiction where the Mortgaged Property is located, insuring (subject to the
exceptions contained in paragraph (ix)(1) (2) and (3) above) the Seller, its
successors and assigns, as to the first priority lien of the Mortgage in the
original principal

                                  Schedule B-3

<PAGE>

amount of the Mortgage Loan. To the best of the Seller's knowledge, the Seller
is the sole insured of such lender's title insurance policy, such title
insurance policy has been duly and validly endorsed to the Purchaser or the
assignment to the Purchaser of the Seller's interest therein does not require
the consent of or notification to the insurer and such lender's title insurance
policy is in full force and effect and will be in full force and effect upon the
consummation of the transactions contemplated by this Agreement. To the best of
the Seller's knowledge, no claims have been made under such lender's title
insurance policy, and no prior holder of the related Mortgage has done, by act
or omission, anything which would impair the coverage of such lender's title
insurance policy;

         (n) To the best of the Seller's knowledge, there is no default, breach,
violation or event of acceleration existing under the Mortgage or the related
Mortgage Note and no event which, with the passage of time or with notice and
the expiration of any grace or cure period, would constitute a default, breach,
violation or event permitting acceleration, except for any Mortgage Loan payment
which is not late by more than 30 days, and the Seller has not waived any
default, breach, violation or event permitting acceleration;

         (o) To the best of the Seller's knowledge, there are no mechanics' or
similar liens or claims which have been filed for work, labor or material (and,
to the best of the Seller's knowledge, no rights are outstanding that under law
could give rise to such lien) affecting the related Mortgaged Property which are
or may be liens prior to, or equal or coordinate with, the lien of the related
Mortgage;

         (p) To the best of the Seller's knowledge, all improvements subject to
the Mortgage, lay wholly within the boundaries and building restriction lines of
the Mortgaged Property (and wholly within the project with respect to a
condominium unit) and no improvements on adjoining properties encroach upon the
Mortgaged Property except those which are insured against by the title insurance
policy referred to in paragraph (xiii) above and all improvements on the
property comply with all applicable zoning and subdivision laws and ordinances;

         (q) To the best of the Seller's knowledge, each Mortgage Loan was
originated by the Seller or by a savings association, a savings bank, a
commercial bank or similar banking institution that is supervised and examined
by a Federal or state banking authority, a mortgagee approved by the Secretary
of HUD pursuant to Section 203 and 211 of the National Housing Act, or a FNMA-
or FHLMC-approved seller. To the best of the Seller's knowledge, each Mortgage
Loan was underwritten generally in accordance with the Underwriting Standards as
in effect at the time of origination. To the best of the Seller's knowledge, the
Mortgage contains the usual and customary provision of the Seller at the time of
origination for the acceleration of the payment of the unpaid principal balance
of the Mortgage Loan if the related Mortgaged Property is sold without the prior
consent of the mortgagee thereunder;

         (r) The Mortgaged Property at origination or acquisition was and, to
the best of the Seller's knowledge, currently is free of material damage and
waste and at origination there was, and to the best of the Seller's knowledge
there currently is, no proceeding pending for the total or partial condemnation
thereof;

                                  Schedule B-4

<PAGE>

         (s) The related Mortgage contains customary and enforceable provisions
such as to render the rights and remedies of the holder thereof adequate for the
realization against the Mortgaged Property of the benefits of the security
provided thereby, including, (1) in the case of a Mortgage designated as a deed
of trust, by trustee's sale or judicial foreclosure, and (2) otherwise by
judicial foreclosure. The Seller has no knowledge of any homestead or other
exemption available to the Mortgagor which would interfere with the right to
sell the Mortgaged Property at a trustee's sale or the right to foreclose the
Mortgage;

         (t) To the best of the Seller's knowledge, if the Mortgage constitutes
a deed of trust, a trustee, duly qualified if required under applicable law to
act as such, has been properly designated and currently so serves and is named
in the Mortgage, and no fees or expenses are or will become payable to the
trustee under the deed of trust, except in connection with a trustee's sale or
attempted sale after default by the Mortgagor;

         (u) With respect to each Mortgage Loan, there is either (i) an
automated property valuation report or (ii) an appraisal on a FNMA-approved form
(or a narrative residential appraisal) of the related Mortgaged Property that
conforms to the applicable requirements of the Financial Institutions Reform
Recovery and Enforcement Act and that was signed prior to the approval of such
Mortgage Loan application by a qualified appraiser, appointed by the Seller or
the Originator of such Mortgage Loan, as appropriate, who has no interest,
direct or indirect, in the Mortgaged Property or in any loan made on the
security thereof, and whose compensation is not affected by the approval or
disapproval of such Mortgage Loan;

         (v) No Mortgage Loan contains "subsidized buydown" or "graduated
payment" features;

         (w) The Mortgaged Property is a single-family (one- to four-unit)
dwelling residence erected thereon, or an individual condominium unit in a
condominium, or a Co-operative Apartment or an individual unit in a planned unit
development or in a de minimis planned unit development as defined by FNMA. No
such residence is a mobile home or a manufactured dwelling which is not
permanently attached to the land;

         (x) No Mortgage Loan provides for negative amortization;

         (y) No Mortgage Loan had an original term in excess of thirty (30)
years;

         (z) With respect to any Mortgage Loan the related Mortgaged Property of
which is located in the City of New York, such Mortgage Loan was originated
prior toFebruary 18, 2003.

         (aa) Each Mortgage Loan is a "qualified mortgage" within the meaning of
Section 860G(a)(3) of the Code (without regard to Treasury Regulations Section
1.860G-2(f) or any similar rule that provides that a defective obligation is a
qualified mortgage for a temporary period);

         (bb) No Mortgage Loan provides for interest other than at either (x) a
single fixed rate in effect throughout the term of the Mortgage Loan or (y) a
single "variable rate" (within the meaning of Treasury Regulations Section
1.860G-1(a)(3)) in effect throughout the term of the Mortgage Loan.

                                  Schedule B-5

<PAGE>

         (cc) No Mortgage Loan is the subject of pending or final foreclosure
proceedings.

         (dd) Based on delinquencies in payment on the Mortgage Loans, the
Seller would not initiate foreclosure proceedings with respect to any of the
Mortgage Loans prior to the next scheduled payment date on such Mortgage Loan.

         (ee) No Mortgage Loan contains any term or condition, or involves any
loan origination practice, that has been defined as "predatory", "covered", or
"threshold" under any applicable federal, state, or local law, and in such
context has been expressly categorized as an "unfair" or "deceptive" term,
condition, or practice in any applicable federal, state, or local law dealing
with "predatory" or "high cost" mortgage lending.

         (ff) None of the Mortgage Loans are "Home Loans" or "High Cost Home
Loans" subject to or covered by the Georgia Fair Lending Act of 2002.

                                  Schedule B-6
