         This Pooling and Servicing Agreement, dated and effective as of
November 1, 2003 (this "Agreement"), is executed by and among Deutsche Alt-A
Securities, Inc., as depositor (the "Depositor"), Wells Fargo Bank Minnesota,
National Association, as master servicer (the "Master Servicer") and securities
administrator (the "Securities Administrator"), and HSBC Bank USA, as trustee
(the "Trustee"). Capitalized terms used in this Agreement and not otherwise
defined have the meanings ascribed to such terms in Article I hereof.

                              PRELIMINARY STATEMENT

         The Depositor at the Closing Date is the owner of the Loans and the
other property being conveyed by it to the Trustee for inclusion in the Trust
Fund. On the Closing Date, the Depositor will acquire the Certificates from the
Trust Fund as consideration for its transfer to the Trust Fund of the Loans and
certain other assets and will be the owner of the Certificates. The Depositor
has duly authorized the execution and delivery of this Agreement to provide for
the conveyance to the Trustee of the Loans and the issuance to the Depositor of
the Certificates representing in the aggregate the entire beneficial ownership
of the Trust Fund. All covenants and agreements made by the Depositor, the
Master Servicer, the Securities Administrator and the Trustee herein with
respect to the 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,
the Master Servicer and the Securities Administrator are entering into this
Agreement, and the Trustee is accepting the trust created hereby, for good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged.

         The Certificates issued hereunder, other than the Class CE, Class P and
Class R Certificates, have been offered for sale pursuant to a Prospectus, dated
August 25, 2003, and a Prospectus Supplement, dated November 21, 2003 of the
Depositor (together, the "Prospectus"). The Trust Fund created hereunder is
intended to be the "Trust" as described in the Prospectus and the Certificates
are intended to be the "Certificates" described therein.

         As provided herein, the Trustee shall elect to treat the segregated
pool of assets consisting of the Loans and other related assets (other than the
Reserve Fund) in the Trust Fund subject to this Agreement as multiple REMICs for
federal income tax purposes, and such segregated pool of assets shall be
designated as "REMIC I." Component R-1 of the Class R Certificate shall
represent the sole class of "residual interests" in REMIC I for purposes of the
REMIC Provisions under federal income tax law. The following table irrevocably
sets forth the designation, the Uncertificated REMIC I Pass-Through Rate, the
initial Uncertificated Principal Balance, and solely for purposes of satisfying
Treasury regulation Section 1.860G-1(a)(4)(iii), the "latest possible maturity
date" for each of the Uncertificated REMIC I Regular Interests. None of the
Uncertificated REMIC I Regular Interests will be certificated.

(2)      Calculated in accordance with the definition of "Uncertificated REMIC
         II Pass-Through Rate" herein. (3) The REMIC II Regular Interest LTII-IO
         will represent 12 REMIC regular interest components, REMIC II
         Regular Interest Component IO-1 through Component IO-12. Each REMIC
         Regular Interest Component IO-2, IO-4, IO-6, IO-8, IO-10 and IO-12 will
         have (a) a rate of 3.50% per annum for the first 24 Distribution Dates
         and thereafter a rate of 0.00% and (b) an uncertificated notional
         amount equal to the Uncertificated Principal Balance of the REMIC I
         Regular Interest for which such component is the Corresponding
         Interest. Each REMIC Regular Interest Component IO-1, IO-3, IO-5, IO-7,
         IO-9 and IO-11 will have (a) a rate of 1.00% per annum for the first 10
         Distribution Dates and thereafter a rate of 0.00% and (b) an
         uncertificated notional amount equal to the Uncertificated Principal
         Balance of the REMIC I Regular Interest for which such component is the
         Corresponding Interest.
(4)      REMIC II Regular Interest LTII-IO will not have an Uncertificated
         Principal Balance, but will accrue interest on its uncertificated
         notional amount calculated in accordance with the definition of
         "Uncertificated Notional Amount" herein.

         As provided herein, the Trustee shall elect to treat the segregated
pool of assets consisting of the REMIC II Regular Interests as a REMIC for
federal income tax purposes, and such segregated pool of assets shall be
designated as "REMIC III". Component R-3 of the Class R Certificate shall
represent the sole class of "residual interests" in REMIC III for purposes of
the REMIC Provisions under federal income tax law. The following table
irrevocably sets forth the designations, the Remittance Rate and initial Class
Principal Balance for each Class of Certificates which, together with the Class
R-3 Component, constitute the entire beneficial interests in REMIC III.
Determined solely for purposes of satisfying Treasury regulation section
1.860G-1(a)(4)(iii), the "latest possible maturity date" for each Class of
Certificates shall be the first Distribution Date that is two years after the
end of the remaining amortization schedule of the Loan in the Mortgage Pool that
has, as of the Closing Date, the longest remaining amortization schedule,
irrespective of its scheduled maturity:

<PAGE>

principal from the cash flow on the Loans and the other assets in the Trust
Fund. The Certificate Principal Balance of a Senior Certificate, Class M

the initial Certificate Principal Balance of such Certificate reduced by the

giving any consent pursuant to this Agreement, any Certificate registered in the
name of the Depositor, the Master Servicer, the Securities Administrator, the
Trustee or any Affiliate thereof shall be deemed not to be outstanding and the
Percentage Interest evidenced thereby shall not be taken into account in
determining whether the requisite percentage of Percentage Interests necessary
to effect any such consent has been obtained. The Trustee or the Securities
Administrator may conclusively rely upon a certificate of the Depositor, the
Seller or the Master Servicer in determining whether a Certificate is held by an
Affiliate thereof. All references herein to "Holders" or "Certificateholders"
shall reflect the rights of Certificate Owners as they may indirectly exercise
such rights through the Depository and participating members thereof, except as
otherwise specified herein; provided, however, that the Trustee or the
Securities Administrator shall be required to recognize as a "Holder" or
"Certificateholder" only the Person in whose name a Certificate is registered in
the Certificate Register. With respect to the Class A-6A Certificates, MBIA

(a) Upon discovery or receipt of notice of any materially defective document in,
or that a document is missing from, a Mortgage File or of a breach by the Seller
of any representation, warranty or covenant under the Mortgage Loan Purchase
Agreement in respect of any Loan that materially and adversely affects the value
of such Loan or the interest therein of



                                      -45-
<PAGE>

the Certificateholders (determined without regard to the Class A-6A Policy), the
Trustee shall promptly notify the Seller of such defect, missing document or
breach and request that the Seller deliver such missing document, cure such
defect or breach within 60 days from the date the Seller was notified of such
missing document, defect or breach, and if the Seller does not deliver such
missing document or cure such defect or breach in all material respects during
such period, the Trustee shall enforce the obligations of the Seller under the
Mortgage Loan Purchase Agreement to repurchase such Loan from REMIC I at the
Purchase Price within 90 days after the date on which the Seller was notified of
such missing document, defect or breach, if and to the extent that the Seller is
obligated to do so under the Mortgage Loan Purchase Agreement. The Purchase
Price for the repurchased Loan shall be deposited in the Distribution Account
and the Trustee, upon receipt of written certification from the Securities
Administrator of such deposit and receipt by the Custodian of a properly
completed request for release for such Loan in the form of Exhibit 3 to the
Custodial Agreement, shall release or cause the Custodian to release to the
Seller the related Mortgage File and the Trustee shall execute and deliver such
instruments of transfer or assignment, in each case without recourse,
representation or warranty, as the Seller shall furnish to it and as shall be
necessary to vest in the Seller any Loan released pursuant hereto, and the
Trustee shall not have any further responsibility with regard to such Mortgage
File. In lieu of repurchasing any such Loan as provided above, if so provided in
the Mortgage Loan Purchase Agreement, the Seller may cause such Loan to be
removed from REMIC I (in which case it shall become a Deleted Loan) and
substitute one or more Substitute Loans in the manner and subject to the
limitations set forth in Section 2.3(b). It is understood and agreed that the
obligation of the Seller to cure or to repurchase (or to substitute for) any
Loan as to which a document is missing, a material defect in a constituent
document exists or as to which such a breach has occurred and is continuing
shall constitute the sole remedy respecting such omission, defect or breach
available to the Trustee and the Certificateholders.

                  In addition, promptly upon the earlier of discovery by the
Master Servicer or receipt of notice by a Responsible Officer of the Master
Servicer of the breach of the representation or covenant of the Seller set forth
in Section 5(x) of the Mortgage Loan Purchase Agreement which materially and
adversely affects the interests of the Holders of the Class P Certificates in
any Prepayment Charge, the Master Servicer shall promptly notify the Seller and
the Trustee of such breach. The Trustee shall enforce the obligations of the
Seller under the Mortgage Loan Purchase Agreement to remedy such breach to the
extent and in the manner set forth in the Mortgage Loan Purchase Agreement.

                  (b) Any substitution of Substitute Loans for Deleted Loans
made pursuant to Section 2.3(a) must be effected prior to the date which is two
years after the Startup Day for the REMIC I.

                  As to any Deleted Loan for which the Seller, substitutes a
Substitute Loan or Loans, such substitution shall be effected by the Seller
delivering to the Trustee or the Custodian on behalf of the Trustee, for such
Substitute Loan or Loans, the Mortgage Note, the Mortgage, the Assignment to the
Trustee, and such other documents and agreements, with all necessary
endorsements thereon, as are required by Section 2 of the Custodial Agreement,
as applicable, together with an Officers' Certificate providing that each such
Substitute Loan satisfies the definition thereof and specifying the Substitution
Shortfall Amount (as described below), if any, in connection with such
substitution. The Custodian on behalf of the Trustee shall acknowledge

                                      -46-
<PAGE>

receipt of such Substitute Loan or Loans and, within ten Business Days
thereafter, review such documents and deliver to the Depositor, the Trustee,
MBIA and the Master Servicer, with respect to such Substitute Loan or Loans, an
initial certification pursuant to the Custodial Agreement, with any applicable
exceptions noted thereon. Within one year of the date of substitution, the
Custodian on behalf of the Trustee shall deliver to the Depositor, the Trustee,
MBIA and the Master Servicer a final certification pursuant to the Custodial
Agreement with respect to such Substitute Loan or Loans, with any applicable
exceptions noted thereon. Monthly Payments due with respect to Substitute Loans
in the month of substitution are not part of REMIC I and shall be retained by
the Seller. For the month of substitution, distributions to Certificateholders
shall reflect the Monthly Payment due on such Deleted Loan on or before the Due
Date in the month of substitution, and the Seller shall thereafter be entitled
to retain all amounts subsequently received in respect of such Deleted Loan. The
Depositor shall give or cause to be given written notice to the
Certificateholders and MBIA that such substitution has taken place, shall amend
the Loan Schedule to reflect the removal of such Deleted Loan from the terms of
this Agreement and the substitution of the Substitute Loan or Loans and shall
deliver a copy of such amended Loan Schedule to the Trustee, MBIA and the Master
Servicer. Upon such substitution, such Substitute Loan or Loans 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 Agreement including all applicable
representations and warranties thereof included herein or in the Mortgage Loan
Purchase Agreement.

                  For any month in which the Seller substitutes one or more
Substitute Loans for one or more Deleted Loans, the Master Servicer shall
determine the amount (the "Substitution Shortfall Amount"), if any, by which the
aggregate Purchase Price of all such Deleted Loans exceeds the aggregate of, as
to each such Substitute Loan, the Scheduled Principal Balance thereof as of the
Due Date in the month of substitution, together with one month's interest on
such Scheduled Principal Balance at the applicable Net Mortgage Rate, plus all
outstanding Advances and Servicing Advances (including Nonrecoverable Advances)
related thereto. On the date of such substitution, the Seller shall deliver or
cause to be delivered to the Securities Administrator for deposit in the
Distribution Account an amount equal to the Substitution Shortfall Amount, if
any, and the Trustee or the Custodian on behalf of the Trustee, upon receipt of
the related Substitute Loan or Loans and certification by the Securities
Administrator of such deposit and receipt by the Custodian of a properly
completed request for release for such Loan in the form of Exhibit 3 to the
Custodial Agreement, shall release to the Seller the related Mortgage File or
Files and the Trustee shall execute and deliver such instruments of transfer or
assignment, in each case without recourse, representation or warranty, as the
Seller shall deliver to it and as shall be necessary to vest therein any Deleted
Loan released pursuant hereto.

                  In addition, the Seller shall obtain at its own expense and
deliver to the Trustee and MBIA an Opinion of Counsel to the effect that such
substitution will not cause (a) any federal tax to be imposed on any REMIC,
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 (b) any REMIC to fail
to qualify as a REMIC at any time that any Certificate is outstanding.

                  (c) Upon discovery by the Depositor, the Seller, the Master
Servicer or the Trustee that any Loan does not constitute a "qualified mortgage"
within the meaning of Section

                                      -47-
<PAGE>

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 shall repurchase or substitute one or more Substitute
Loans for the affected Loan within 90 days of the earlier of discovery or
receipt of such notice with respect to such affected Loan. Such repurchase or
substitution shall be made by (i) the Seller, if the affected Loan's status as a
non-qualified mortgage is or results from a breach of any representation,
warranty or covenant made by the Seller under the Mortgage Loan Purchase
Agreement or (ii) the Depositor, if the affected Loan's status as a
non-qualified mortgage does not result from a breach of representation or
warranty. Any such repurchase or substitution shall be made in the same manner
as set forth in Section 2.3(a). The Trustee shall reconvey to the Seller or the
Depositor the Loan to be released pursuant hereto in the same manner, and on the
same terms and conditions, as it would a Loan repurchased for breach of a
representation or warranty.

                  (d) Within 90 days of the earlier of discovery by the Master
Servicer or receipt of notice by the Master Servicer of the breach of any
representation, warranty or covenant of the Master Servicer set forth in Section
2.5 which materially and adversely affects the interests of the
Certificateholders (determined without regard to the Class A-6A Policy) in any
Loan or Prepayment Charge, the Master Servicer shall cure such breach in all
material respects.

                  Section 2.4 Authentication and Delivery of Certificates;
                              Designation of Certificates as REMIC Regular and
                              Residual Interests.

         (a) The Trustee acknowledges the transfer to the extent provided herein
and assignment to it of the Trust Fund and, concurrently with such transfer and
assignment, has caused the Securities Administrator to execute and authenticate
and has delivered to or upon the order of the Depositor, in exchange for the
Trust Fund, Certificates evidencing the entire ownership of the Trust Fund.

         (b) This Agreement shall be construed so as to carry out the intention
of the parties that each of REMIC I, REMIC II, and REMIC III be treated as a
REMIC at all times prior to the date on which the Trust Fund is terminated. The
"regular interests" (within the meaning of Section 860G(a)(1) of the Code) in
REMIC III shall consist of the Class A Certificates, the Mezzanine Certificates,
the Class CE Certificates and the Class P Certificate. The "residual interest"
(within the meaning of Section 860G(a)(2) of the Code) in REMIC III shall
consist of the Class R-3 Interest. The "regular interests" (within the meaning
of Section 860G(a)(1) of the Code) of REMIC II shall consist of the REMIC II
Regular Interest. The "residual interest" (within the meaning of Section
860(G)(a)(2) of the Code) of REMIC II shall consist of the Class R-2 Interest.
The "regular interests" (within the meaning of Section 860G(a)(1) of the Code)
of REMIC I shall consist the REMIC I Regular Interests. The "residual interest"
(within the meaning of Section 860(G)(a)(2) of the Code) of REMIC I shall
consist of the Class R-1 Interest.

         Section 2.5 Representations and Warranties of the Master Servicer.

         The Master Servicer hereby represents, warrants and covenants to the
Trustee, for the benefit of each of the Trustee, the Certificateholders, MBIA
and the Depositor that as of the Closing Date or as of such date specifically
provided herein:

               reorganization or similar laws affecting the enforcement of
               creditors' rights generally and by general principles of equity;

                    (iii) The execution and delivery of this Agreement by the

               of any court, regulatory body, administrative agency or
               governmental body having jurisdiction over it, which materially
               and adversely affects or, to the Master Servicer's knowledge,
               would in the future materially and adversely affect, (x) the

               this Agreement or (y) the business, operations, financial
               condition, properties or assets of the Master Servicer taken as a

               hereunder in accordance with the terms hereof,

               its entering into this Agreement, (B) seeking to prevent the
               consummation of the transactions contemplated by this Agreement
               or (C) that might

               Date.

         It is understood and agreed that the representations, warranties and
covenants set forth in this Section 2.5 shall inure to the benefit of the

               ADMINISTRATION AND SERVICING OF THE LOANS; ACCOUNTS

         Section 3.1 Master Servicer. The Master Servicer shall supervise,
monitor and oversee the obligation of the Servicers to service and administer
their respective Loans in accordance with the terms of the applicable Servicing
Agreement and shall have full power and authority to do any and all things which
it may deem necessary or desirable in connection with such master servicing and
administration. In performing its obligations hereunder, the Master Servicer
shall act in a manner consistent with Accepted Master Servicing Practices.
Furthermore, the Master Servicer shall oversee and consult with each Servicer as
necessary from time-to-time to carry out the Master Servicer's obligations
hereunder, shall receive, review and evaluate all reports, information and other
data provided to the Master Servicer by each Servicer and shall cause each
Servicer to perform and observe the covenants, obligations and conditions to be
performed or observed by such Servicer under the applicable Servicing Agreement.
The Master Servicer shall independently and separately monitor each Servicer's
servicing activities with respect to each related Loan, reconcile the results of
such monitoring with such information provided in the previous sentence on a
monthly basis and coordinate corrective adjustments to the Servicers' and Master
Servicer's records, and based on such reconciled and corrected information,
prepare the statements specified in Section 4.3 and any other information and
statements required to be provided by the Master Servicer hereunder. The Master
Servicer shall reconcile the results of its Loan monitoring with the actual
remittances of the Servicers to the Distribution Account pursuant to the
applicable Servicing Agreements.

         Notwithstanding anything in this Agreement or any Servicing Agreement
to the contrary, the Master Servicer shall not have any duty or obligation to
enforce any Credit Risk Management Agreement that a Servicer is a party to (a
"Servicer Credit Risk Management Agreement") or to supervise, monitor or oversee
the activities of the Credit Risk Manager under any such Servicer Credit Risk
Management Agreement with respect to any action taken or not taken by the
applicable Servicer pursuant to a recommendation of the Credit Risk Manager.

         The Trustee shall furnish the Servicers and the Master Servicer with
any limited powers of attorney and other documents in form as provided to it
necessary or appropriate to enable the Servicers and the Master Servicer to
service or master service and administer the related Loans and REO Property. The
Trustee shall have no responsibility for any action of the Master Servicer or
any Servicer pursuant to any such limited power of attorney and shall be
indemnified by the Master Servicer or such Servicer for any cost, liability or
expense arising from the misuse thereof by the Master Servicer or such Servicer.

         The Trustee, the Custodian and the Securities Administrator shall
provide access to the records and documentation in possession of the Trustee,
the Custodian or the Securities Administrator regarding the related Loans and
REO Property and the servicing thereof to the Certificateholders, MBIA, the
FDIC, and the supervisory agents and examiners of the FDIC, such access being
afforded only upon reasonable prior written request and during normal business
hours at the office of the Trustee, the Custodian or the Securities
Administrator; provided, however, that, unless otherwise required by law, none
of the Trustee, the Custodian or the Securities Administrator shall be required
to provide access to such records and



                                      -51-
<PAGE>

documentation if the provision thereof would violate the legal right to privacy
of any Mortgagor. The Trustee, the Custodian and the Securities Administrator
shall allow representatives of the above entities to photocopy any of the
records and documentation and shall provide equipment for that purpose at a
charge that covers the Trustee's, the Custodian's or the Securities
Administrator's actual costs.

         The Trustee shall execute and deliver to the related Servicer or the
Master Servicer upon request any court pleadings, requests for trustee's sale or
other documents necessary or desirable and, in each case, provided to the
Trustee by such Servicer or Master Servicer to (i) the foreclosure or trustee's
sale with respect to a Mortgaged Property; (ii) any legal action brought to
obtain judgment against any Mortgagor on the Mortgage Note or any other Loan
Document; (iii) obtain a deficiency judgment against the Mortgagor; or (iv)
enforce any other rights or remedies provided by the Mortgage Note or any other
Loan Document or otherwise available at law or equity.

         Section 3.2 REMIC-Related Covenants. For as long as each REMIC shall
exist, the Trustee and the Securities Administrator shall treat such REMIC as a
REMIC, and the Trustee and the Securities Administrator shall comply with any
directions of the Seller, the related Servicer or the Master Servicer to assure
such continuing treatment. In particular, the Trustee shall not (a) sell or
permit the sale of all or any portion of the Loans or of any investment of
deposits in an Account unless such sale is as a result of a repurchase of the
Loans pursuant to this Agreement or the Trustee and MBIA have received an
Opinion of Counsel stating that such sale will not result in an Adverse REMIC
Event as defined in Section 10.1(f) hereof prepared at the expense of the Trust
Fund; and (b) other than with respect to a substitution pursuant to the Mortgage
Loan Purchase Agreements, the Assignment Agreements or Section 2.3 of this
Agreement, as applicable, accept any contribution to any REMIC after the Startup
Day without receipt of an Opinion of Counsel stating that such contribution will
not result in an Adverse REMIC Event as defined in Section 10.1(f) hereof.

         Section 3.3 Monitoring of Servicers.

         (a) The Master Servicer shall be responsible for monitoring the
compliance by each Servicer with its duties under the related Servicing
Agreement. In the review of each Servicer's activities, the Master Servicer may
rely upon an officer's certificate of any Servicer with regard to such
Servicer's compliance with the terms of its Servicing Agreement. In the event
that the Master Servicer, in its judgment, determines that a Servicer should be
terminated in accordance with its Servicing Agreement, or that a notice should
be sent pursuant to such Servicing Agreement with respect to the occurrence of
an event that, unless cured, would constitute grounds for such termination, the
Master Servicer shall notify the Seller, MBIA and the Trustee thereof and the
Master Servicer shall issue such notice or take such other action as it deems
appropriate.

         (b) The Master Servicer, for the benefit of the Trustee and the
Certificateholders, shall enforce the obligations of each Servicer under the
related Servicing Agreement, and shall, in the event that a Servicer fails to
perform its obligations in accordance with the related Servicing Agreement,
subject to the preceding paragraph, terminate the rights and obligations of such
Servicer thereunder and act as servicer of the related Loans or to cause

                                      -52-
<PAGE>

the Trustee to enter in to a new Servicing Agreement with a successor Servicer
selected by the Master Servicer; provided, however, it is understood and
acknowledged by the parties hereto that there will be a period of transition
(not to exceed 90 days) before the actual servicing functions can be fully
transferred to such successor Servicer. Such enforcement, including, without
limitation, the legal prosecution of claims, termination of Servicing Agreements
and the pursuit of other appropriate remedies, shall be in such form and carried
out to such an extent and at such time as the Master Servicer, in its good faith
business judgment, would require were it the owner of the related Loans. The
Master Servicer shall pay the costs of such enforcement at its own expense,
provided that the Master Servicer shall not be required to prosecute or defend
any legal action except to the extent that the Master Servicer shall have
received reasonable indemnity for its costs and expenses in pursuing such
action.

         (c) To the extent that the costs and expenses of the Master Servicer
related to any termination of a Servicer, appointment of a successor Servicer or
the transfer and assumption of servicing by the Master Servicer with respect to
any Servicing Agreement (including, without limitation, (i) all legal costs and
expenses and all due diligence costs and expenses associated with an evaluation
of the potential termination of the Servicer as a result of an event of default
by such Servicer and (ii) all costs and expenses associated with the complete
transfer of servicing, including all servicing files and all servicing data and
the completion, correction or manipulation of such servicing data as may be
required by the successor servicer to correct any errors or insufficiencies in
the servicing data or otherwise to enable the successor servicer to service the
Loans in accordance with the related Servicing Agreement) are not fully and
timely reimbursed by the terminated Servicer, the Master Servicer shall be
entitled to reimbursement of such costs and expenses from the Distribution
Account.

         (d) The Master Servicer shall require each Servicer to comply with the
remittance requirements and other obligations set forth in the related Servicing
Agreement.

         (e) If the Master Servicer acts as Servicer, it shall not assume
liability for the representations and warranties of the Servicer, if any, that
it replaces.

         Section 3.4 Fidelity Bond. The Master Servicer, at its expense, shall
maintain in effect a blanket fidelity bond and an errors and omissions insurance
policy that would meet the requirements of Fannie Mae or Freddie Mac, affording
coverage with respect to all directors, officers, employees and other Persons
acting on such Master Servicer's behalf, and covering errors and omissions in
the performance of the Master Servicer's obligations hereunder. The errors and
omissions insurance policy and the fidelity bond shall be in such form and
amount generally acceptable for entities serving as master servicers or
trustees. Any such errors and omissions policy and fidelity bond may not be
cancelable without thirty (30) days' prior written notice to MBIA and the
Trustee.

         Section 3.5 Power to Act; Procedures. The Master Servicer shall master
service the Loans and shall have full power and authority, subject to the REMIC
Provisions and the provisions of Article X hereof, to do any and all things that
it may deem necessary or desirable in connection with the master servicing and
administration of the Loans, including but not limited to the power and
authority (i) to execute and deliver, on behalf of the Certificateholders and
the Trustee, customary consents or waivers and other instruments and documents,
(ii) to consent to

                                      -53-
<PAGE>

transfers of any Mortgaged Property and assumptions of the Mortgage Notes and
related Mortgages, (iii) to collect any Insurance Proceeds and Liquidation
Proceeds, and (iv) to effectuate foreclosure or other conversion of the
ownership of the Mortgaged Property securing any Loan, in each case, in
accordance with the provisions of this Agreement and the related Servicing
Agreement, as applicable; provided, however, that the Master Servicer shall not
(and, consistent with its responsibilities under Section 3.3, shall not permit
any Servicer to) knowingly or intentionally take any action, or fail to take (or
fail to cause to be taken) any action reasonably within its control and the
scope of duties more specifically set forth herein, that, under the REMIC
Provisions, if taken or not taken, as the case may be, would cause REMIC I,
REMIC II or REMIC III to fail to qualify as a REMIC or result in the imposition
of a tax upon the Trust Fund (including but not limited to the tax on prohibited
transactions as defined in Section 860F(a)(2) of the Code and the tax on
contributions to a REMIC set forth in Section 860G(d) of the Code) unless the
Master Servicer, the Securities Administrator and MBIA have received an Opinion
of Counsel (but not at the expense of the Master Servicer, the Securities
Administrator or MBIA) to the effect that the contemplated action will not cause
REMIC I, REMIC II or REMIC III to fail to qualify as a REMIC or result in the
imposition of a tax upon REMIC I, REMIC II or REMIC III, as the case may be. The
Trustee shall furnish the Master Servicer, upon written request from a Servicing
Officer, with any powers of attorney empowering the Master Servicer or any
Servicer to execute and deliver instruments of satisfaction or cancellation, or
of partial or full release or discharge, and to foreclose upon or otherwise
liquidate Mortgaged Property, and to appeal, prosecute or defend in any court
action relating to the Loans or the Mortgaged Property, in accordance with the
applicable Servicing Agreement and this Agreement, and the Trustee shall execute
and deliver such other documents, as the Master Servicer or applicable Servicer
may request, to enable the Master Servicer to master service and administer the
Loans and carry out its duties hereunder, in each case in accordance with
Accepted Master Servicing Practices (and the Trustee shall have no liability for
the misuse of any such powers of attorney by the Master Servicer or any Servicer
and shall be indemnified by the Master Servicer or such Servicer for any costs,
liabilities or expenses incurred by the Trustee in connection with such misuse).
If the Master Servicer or the Trustee has been advised that it is likely that
the laws of the state in which action is to be taken prohibit such action if
taken in the name of the Trustee or that the Trustee would be adversely affected
under the "doing business" or tax laws of such state if such action is taken in
its name, the Master Servicer shall join with the Trustee in the appointment of
a co-trustee pursuant to Section 8.10 hereof. In the performance of its duties
hereunder, the Master Servicer shall be an independent contractor and shall not,
except in those instances where it is taking action authorized pursuant to this
Agreement to be taken by it in the name of the Trustee, be deemed to be the
agent of the Trustee.

         Section 3.6 Due-on-Sale Clauses; Assumption Agreements. To the extent
provided in the applicable Servicing Agreement and to the extent Loans contain
enforceable due-on-sale clauses, the Master Servicer shall cause the Servicers
to enforce such clauses in accordance with the applicable Servicing Agreement.
If applicable law prohibits the enforcement of a due-on-sale clause or such
clause is otherwise not enforced in accordance with the applicable Servicing
Agreement, and, as a consequence, a Loan is assumed, the original Mortgagor may
be released from liability in accordance with the applicable Servicing
Agreement.

         Section 3.7 Release of Mortgage Files.

         (a) Upon becoming aware of the payment in full of any Loan, or the
receipt by any Servicer of a notification that payment in full has been escrowed
in a manner customary for such purposes for payment to Certificateholders on the
next Distribution Date, the applicable Servicer will (or if the Servicer does
not, the Master Servicer may), if required under the applicable Servicing
Agreement, promptly furnish to the Custodian, on behalf of the Trustee, two
copies of a request for release substantially in the form attached to the
Custodial Agreement, and signed by a Servicing Officer or in a mutually
agreeable electronic format which will, in lieu of a signature on its face,
originate from a Servicing Officer (which certification shall include a
statement to the effect that all amounts received in connection with such
payment that are required to be deposited in the Protected Account maintained by
the applicable Servicer pursuant to its Servicing Agreement have been or will be
so deposited) and shall request that the Custodian, on behalf of the Trustee,
deliver to the applicable Servicer the related Mortgage File. Upon receipt of
such certification and request, the Custodian, on behalf of the Trustee, shall
promptly release the related Mortgage File to the applicable Servicer and the
Trustee and Custodian shall have no further responsibility with regard to such
Mortgage File. Upon any such payment in full, each Servicer is authorized to
give, as agent for the Trustee, as the mortgagee under the Mortgage that secured
the Loan, an instrument of satisfaction (or assignment of mortgage without
recourse) regarding the Mortgaged Property subject to the Mortgage, which
instrument of satisfaction or assignment, as the case may be, shall be delivered
to the Person or Persons entitled thereto against receipt therefor of such
payment, it being understood and agreed that no expenses incurred in connection
with such instrument of satisfaction or assignment, as the case may be, shall be
chargeable to the Distribution Account.

         (b) From time to time and as appropriate for the servicing or
foreclosure of any Loan and in accordance with the applicable Servicing
Agreement, the Trustee shall execute such documents as shall be prepared and
furnished to the Trustee by a Servicer or the Master Servicer (in form
reasonably acceptable to the Trustee) and as are necessary to the prosecution of
any such proceedings. The Custodian, on behalf of the Trustee, shall, upon the
request of a Servicer or the Master Servicer, and delivery to the Custodian, on
behalf of the Trustee, of two copies of a request for release signed by a
Servicing Officer substantially in the form attached to the Custodial Agreement
(or in a mutually agreeable electronic format which will, in lieu of a signature
on its face, originate from a Servicing Officer), release the related Mortgage
File held in its possession or control to the Servicer or the Master Servicer,
as applicable. Such request for release shall obligate the Servicer or the
Master Servicer to return the Mortgage File to the Custodian on behalf of the
Trustee, when the need therefor by the Servicer or the Master Servicer no longer
exists unless the Loan shall be liquidated, in which case, upon receipt of a
certificate of a Servicing Officer similar to that hereinabove specified, the
Mortgage File shall be released by the Custodian, on behalf of the Trustee, to
the Servicer or the Master Servicer.

         Section 3.8 Documents, Records and Funds in Possession of Master
Servicer To Be Held for Trustee.

(a) The Master Servicer shall transmit and each Servicer (to the extent required
by the related Servicing Agreement) shall transmit to the Trustee or Custodian
such documents and instruments coming into the possession of the Master Servicer
or such Servicer

                                      -55-
<PAGE>

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

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

         Section 3.9 Standard Hazard Insurance and Flood Insurance Policies.

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

         (b) Pursuant to Section 3.23, any amounts collected by the Master
Servicer, or by any Servicer, under any insurance policies (other than amounts
to be applied to the restoration or repair of the property subject to the
related Mortgage or released to the Mortgagor in accordance with the applicable
Servicing Agreement) shall be deposited into the Distribution Account, subject
to withdrawal pursuant to Section 3.24. Any cost incurred by the Master Servicer
or any Servicer in maintaining any such insurance if the Mortgagor defaults in
its

                                      -56-
<PAGE>

obligation to do so shall be added to the amount owing under the Loan where the
terms of the Loan so permit; provided, however, that the addition of any such
cost shall not be taken into account for purposes of calculating the
distributions to be made to Certificateholders and shall be recoverable by the
Master Servicer or such Servicer pursuant to Section 3.24.

         Section 3.10 Presentment of Claims and Collection of Proceeds. The
Master Servicer shall (to the extent provided in the applicable Servicing
Agreement) cause the related Servicer to, prepare and present on behalf of the
Trustee and the Certificateholders all claims under any insurance policies and
take such actions (including the negotiation, settlement, compromise or
enforcement of the insured's claim) as shall be necessary to realize recovery
under such policies. Any proceeds disbursed to the Master Servicer (or disbursed
to a Servicer and remitted to the Master Servicer) in respect of such policies,
bonds or contracts shall be promptly deposited in the Distribution Account upon
receipt, except that any amounts realized that are to be applied to the repair
or restoration of the related Mortgaged Property as a condition precedent to the
presentation of claims on the related Loan to the insurer under any applicable
insurance policy need not be so deposited (or remitted).

         Section 3.11 Maintenance of the Primary Mortgage Insurance Policies.

         (a) The Master Servicer shall not take, or permit any Servicer (to the
extent such action is prohibited under the applicable Servicing Agreement) to
take, any action that would result in noncoverage under any primary mortgage
insurance policy of any loss which, but for the actions of such Master Servicer
or Servicer, would have been covered thereunder. The Master Servicer shall use
its best reasonable efforts to cause each Servicer (to the extent required under
the related Servicing Agreement) to keep in force and effect (to the extent that
the Loan requires the Mortgagor to maintain such insurance), primary mortgage
insurance applicable to each Loan in accordance with the provisions of this
Agreement and the related Servicing Agreement, as applicable. The Master
Servicer shall not, and shall not permit any Servicer (to the extent required
under the related Servicing Agreement) to, cancel or refuse to renew any primary
mortgage insurance policy that is in effect at the date of the initial issuance
of the Mortgage Note and is required to be kept in force hereunder except in
accordance with the provisions of this Agreement and the related Servicing
Agreement, as applicable.

         (b) The Master Servicer agrees to cause each Servicer (to the extent
required under the related Servicing Agreement) to present, on behalf of the
Trustee and the Certificateholders, claims to the insurer under any primary
mortgage insurance policies and, in this regard, to take such reasonable action
as shall be necessary to permit recovery under any primary mortgage insurance
policies respecting defaulted Loans. Pursuant to Section 3.22 and 3.23, any
amounts collected by the Master Servicer or any Servicer under any primary
mortgage insurance policies shall be deposited by the related Servicer in its
Protected Account or by the Master Servicer in the Distribution Account, subject
to withdrawal pursuant to Sections 3.22 or 3.24, as applicable.

         Section 3.12 Trustee to Retain Possession of Certain Insurance Policies
and Documents.

                  The Trustee or the applicable Custodian, shall retain
possession and custody of the originals (to the extent available) of any primary
mortgage insurance policies, or certificate

                                      -57-
<PAGE>

of insurance if applicable, and any certificates of renewal as to the foregoing
as may be issued from time to time as contemplated by this Agreement. Until all
amounts distributable in respect of the Certificates and all amounts payable to
MBIA have been distributed in full and the Master Servicer otherwise has
fulfilled its obligations under this Agreement, the Trustee or the Custodian
shall also retain possession and custody of each Mortgage File in accordance
with and subject to the terms and conditions of this Agreement and the Custodial
Agreement. The Master Servicer shall promptly deliver or cause to be delivered
to the Trustee or the Custodian, upon the execution or receipt thereof the
originals of any primary mortgage insurance policies, any certificates of
renewal, and such other documents or instruments that constitute Loan Documents
that come into the possession of the Master Servicer from time to time.

         Section 3.13 Realization Upon Defaulted Loans. The Master Servicer
shall cause each Servicer (to the extent required under the related Servicing
Agreement) to foreclose upon, repossess or otherwise comparably convert the
ownership of Mortgaged Properties securing such of the Loans as come into and
continue in default and as to which no satisfactory arrangements can be made for
collection of delinquent payments, all in accordance with the applicable
Servicing Agreement.

         Section 3.14 Compensation for the Master Servicer.

         (a) In addition to the Master Servicer's right to receive its Master
Servicing Fee, all income and gain realized from any investment of funds in the
Distribution Account shall be for the benefit of the Master Servicer as
compensation. Servicing compensation in the form of assumption fees, if any,
late payment charges, as collected, if any, or otherwise (but not including any
Prepayment Charges) shall be retained by the applicable Servicer and shall not
be deposited in the Protected Account. The Master Servicer shall be required to
pay all expenses incurred by it in connection with its activities hereunder and
shall not be entitled to reimbursement therefor except as provided in this
Agreement.

         (b) The amount of the aggregate compensation payable as set forth in
Section 3.14(a) (the "Master Servicing Compensation") to the Master Servicer in
respect of any Distribution Date shall be reduced in accordance with Section
3.20.

         Section 3.15 REO Property.

         (a) In the event the Trust Fund acquires ownership of any REO Property
in respect of any related Loan, the deed or certificate of sale shall be issued
to the Trustee, or to its nominee, on behalf of the related Certificateholders
and MBIA. The Master Servicer shall, to the extent provided in the applicable
Servicing Agreement, cause the applicable Servicer to sell any REO Property as
expeditiously as possible and in accordance with the provisions of this
Agreement and the related Servicing Agreement, as applicable. Further, the
Master Servicer shall, to the extent provided in the related Servicing
Agreement, cause the applicable Servicer to sell any REO Property prior to three
years after the end of the calendar year of its acquisition by REMIC I unless
(i) the Trustee, the Securities Administrator and MBIA shall have been supplied
with an Opinion of Counsel to the effect that the holding by the Trust Fund of
such REO Property subsequent to such three-year period will not result in the
imposition of taxes on "prohibited transactions" of any REMIC hereunder as
defined in section 860F of the Code or cause any REMIC hereunder to fail to
qualify as a REMIC at any time that any Certificates are



                                      -58-
<PAGE>

outstanding, in which case the Trust Fund may continue to hold such Mortgaged
Property (subject to any conditions contained in such Opinion of Counsel) or
(ii) the applicable Servicer shall have applied for, prior to the expiration of
such three-year period, an extension of such three-year period in the manner
contemplated by Section 856(e)(3) of the Code, in which case the three-year
period shall be extended by the applicable extension period. The Master Servicer
shall cause the applicable Servicer (to the extent provided in the related
Servicing Agreement) to protect and conserve, such REO Property in the manner
and to the extent required by the applicable Servicing Agreement, in accordance
with the REMIC Provisions and in a manner that does not result in a tax on "net
income from foreclosure property" or cause such REO Property to fail to qualify
as "foreclosure property" within the meaning of Section 860G(a)(8) of the Code.

         (b) The Master Servicer shall, to the extent required by the related
Servicing Agreement, cause the applicable Servicer to deposit all funds
collected and received in connection with the operation of any REO Property in
the Protected Account.

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

         (d) To the extent provided in the related Servicing Agreement, the
Liquidation Proceeds from the final disposition of the REO Property, net of any
payment to the Master Servicer and the applicable Servicer as provided above
shall be deposited in the Protected Account on or prior to the Determination
Date in the month following receipt thereof and be remitted by wire transfer in
immediately available funds to the Master Servicer for deposit into the
Distribution Account on the next succeeding Remittance Date.

         Section 3.16 Annual Officer's Certificate as to Compliance.

         (a) The Master Servicer shall deliver to the Trustee, MBIA and the
Rating Agencies on or before March 15 of each year, commencing on March 15,
2004, an Officer's Certificate signed by a Servicing Officer, certifying that
with respect to the period ending December 31 of the prior year: (i) such
Servicing Officer has reviewed the activities of such Master Servicer during the
preceding calendar year or portion thereof and its performance under this
Agreement, (ii) to the best of such Servicing Officer's knowledge, based on such
review, such Master Servicer has performed and fulfilled its duties,
responsibilities and obligations under this Agreement in all material respects
throughout such year, or, if there has been a default in the fulfillment of any
such duties, responsibilities or obligations, specifying each such default known
to such Servicing Officer and the nature and status thereof, (iii) nothing has
come to the attention of such Servicing Officer to lead such Servicing Officer
to believe that any Servicer has failed to perform any of its duties,
responsibilities and obligations under its Servicing Agreement in all material
respects throughout such year, or, if there has been a material default in the
performance

                                      -59-
<PAGE>

or fulfillment of any such duties, responsibilities or obligations, specifying
each such default known to such Servicing Officer and the nature and status
thereof.

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

         Section 3.17 Annual Independent Accountant's Servicing Report. If the
Master Servicer has, during the course of any fiscal year, directly serviced any
of the Loans, then the Master Servicer at its expense shall cause a nationally
recognized firm of independent certified public accountants to furnish a
statement to the Trustee and MBIA, the Rating Agencies and the Seller on or
before March 15 of each year, commencing on March 15, 2004 to the effect that,
with respect to the most recently ended fiscal year, such firm has examined
certain records and documents relating to the Master Servicer's performance of
its servicing obligations under this Agreement and pooling and servicing and
trust agreements in material respects similar to this Agreement and to each
other and that, on the basis of such examination conducted substantially in
compliance with the audit program for mortgages serviced for Freddie Mac or the
Uniform Single Attestation Program for Mortgage Bankers, such firm is of the
opinion that the Master Servicer's activities have been conducted in compliance
with this Agreement, or that such examination has disclosed no material items of
noncompliance except for (i) such exceptions as such firm believes to be
immaterial, (ii) such other exceptions as are set forth in such statement and
(iii) such exceptions that the Uniform Single Attestation Program for Mortgage
Bankers or the Audit Program for Mortgages Serviced by Freddie Mac requires it
to report. Copies of such statements shall be provided to any Certificateholder
upon request by the Master Servicer, or by the Trustee at the expense of the
Master Servicer if the Master Servicer shall fail to provide such copies (unless
(i) the Master Servicer shall have failed to provide the Trustee with such
statement or (ii) the Trustee shall be unaware of the Master Servicer's failure
to provide such statement). If such report discloses exceptions that are
material, the Master Servicer shall advise the Trustee whether such exceptions
have been or are susceptible of cure, and shall take prompt action to do so.

         Section 3.18 Reports Filed with Securities and Exchange Commission.

         (a) Within 15 days after each Distribution Date, the Master Servicer
shall, in accordance with industry standards, file with the Commission via the

certification signed by an officer of the Master Servicer that complies with the
Sarbanes-Oxley Act of 2002 as in effect on the date of this Agreement and the
February 3, 2003, Statement by the Staff of the Division of Corporation Finance
of the Commission Regarding Compliance by Asset-Backed Issuers with Exchange Act
Rules 13a-14 and 15d-14 as in effect as of the date of this Agreement. The
Depositor hereby grants to the Master Servicer a limited power of attorney to
execute and file each Form 8-K and Form 10-K on behalf of the Depositor. Such
power of attorney shall continue until either the earlier of (i) receipt by the
Master Servicer from the Depositor of written termination of such power of
attorney and (ii) the termination of the Trust Fund. The Depositor and the
Trustee each agree to promptly furnish to the Master Servicer, from time to time
upon request, such further information, reports and financial statements within
its control related to this Agreement and the Loans as the Master Servicer
reasonably deems appropriate to prepare and file all necessary reports with the
Commission. The Master Servicer shall cooperate with the Depositor in connection
with any additional filings with respect to the Trust Fund as the Depositor
deems necessary under the Exchange Act. Copies of all reports filed by the
Master Servicer under the Exchange Act shall be sent to the Depositor.

         (b) The Master Servicer shall indemnify and hold harmless the
Depositor, the Trustee and their respective officers, directors and Affiliates
from and against any losses, damages, penalties, fines, forfeitures, reasonable
and necessary legal fees and related costs, judgments and other costs and
expenses arising out of or based upon a breach of the Master Servicer's
obligations under this Section 3.18 or the Master Servicer's negligence, bad
faith or willful misconduct in connection therewith. Fees and expenses incurred
by the Master Servicer in connection with this Section 3.18 shall not be
reimbursable from the Trust Fund.

         Section 3.19 UCC. The Depositor shall file any financing statements or
amendments thereto required by any change in the Uniform Commercial Code. The
Depositor agrees to file continuation statements for any such Uniform Commercial
Code financing statements which the Seller or the Depositor filed in connection
with the Trust Fund.

         Section 3.20 Obligation of the Master Servicer in respect of
Compensating Interest. The Master Servicer shall deposit in the Distribution
Account not later than each Distribution Account Deposit Date an amount equal to
the lesser of (i) the aggregate amounts required to be paid by the Servicers
under the Servicing Agreements with respect to Compensating Interest on the
related Loans for the related Distribution Date, and not so paid by the related
Servicers and (ii) the Master Servicing Fee for such Distribution Date without
reimbursement therefor.

         Section 3.21 Reserved.

         Section 3.22 Protected Accounts.

         (a) The Master Servicer shall enforce the obligation of each Servicer
to establish and maintain a Protected Account in accordance with the applicable
Servicing Agreement, with records to be kept with respect thereto on a Loan by
Loan basis, into which accounts shall be deposited within 48 hours (or as of
such other time specified in the related Servicing Agreement) of receipt all
collections of principal and interest on any Loan and with respect to any REO
Property received by a Servicer, including Principal Prepayments, Insurance
Proceeds, Liquidation Proceeds, and advances made from the Servicer's own funds

case of any Servicer) and all other amounts to be deposited in the Protected

the related Servicing Agreement. To the extent provided in the related Servicing
Agreement, the Protected Account shall be held in a depository institution and
segregated on the books of such institution in the name of the Trustee for the
benefit of Certificateholders.

         (b) To the extent provided in the related Servicing Agreement, amounts
on deposit in a Protected Account may be invested in Eligible Investments in the
name of the Trustee for the benefit of Certificateholders and, except as
provided in the preceding paragraph, not commingled with any other funds, such
Eligible Investments to mature, or to be subject to redemption or withdrawal, no
later than the date on which such funds are required to be withdrawn for deposit
in the Distribution Account, and shall be held until required for such deposit.
The income earned from Eligible Investments made pursuant to this Section 3.22
shall be paid to the related Servicer under the applicable Servicing Agreement,
and the risk of loss of moneys required to be distributed to the
Certificateholders and MBIA resulting from such investments shall be borne by
and be the risk of the related Servicer. The related Servicer (to the extent
provided in the Servicing Agreement) shall deposit the amount of any such loss
in the Protected Account within two Business Days of receipt of notification of
such loss but not later than the second Business Day prior to the Distribution
Date on which the moneys so invested are required to be distributed to the
Certificateholders.

         (c) To the extent provided in the related Servicing Agreement and
subject to this Article III, on or before each Servicer Remittance Date, the
related Servicer shall withdraw or shall cause to be withdrawn from the
Protected Accounts and shall immediately deposit or cause to be deposited in the
Distribution Account amounts representing the following collections and payments
(other than with respect to principal of or interest on the Loans due on or

certain amounts otherwise due to the Servicers may be retained by them and need
not be deposited in the Distribution Account.

           Section 3.23    Distribution Account.

         (a) The Securities Administrator shall establish and maintain, for the
benefit of the Certificateholders, the Distribution Account as a segregated
trust account or accounts. The Master Servicer shall deposit in the Distribution
Account as identified by the Master Servicer and as received by the Master
Servicer, the following amounts:

               (i) Any amounts withdrawn from a Protected Account;

               (ii) Any Advance and any amounts in respect of Prepayment
          Interest Shortfalls;

               (iii) Any Insurance Proceeds or Liquidation Proceeds received by
          or on behalf of the Master Servicer;

               (iv) The Purchase Price with respect to any Loans purchased by
          the Seller pursuant to Section 2.3 and all proceeds of any Loans or
          property acquired with respect thereto purchased by the Master
          Servicer pursuant to Section 9.1;

               (v) Any amounts required to be deposited by the Master Servicer
          or any Servicer with respect to losses on investments of deposits in
          an Account; and

               (vi) Any other amounts received by or on behalf of the Master
          Servicer and required to be deposited in the Distribution Account
          pursuant to this Agreement.

         (b) All amounts deposited to the Distribution Account shall be held by
the Securities Administrator in trust for the benefit of the Certificateholders
in accordance with the terms and provisions of this Agreement. The requirements
for crediting the Distribution Account shall be exclusive, it being understood
and agreed that, without limiting the generality of the foregoing, payments in
the nature of late payment charges or assumption, tax service, statement account
or payoff, substitution, satisfaction, release and other like fees and charges,
need not be credited by the Master Servicer or the related Servicer to the
Distribution Account. In the event that the Master Servicer shall deposit or
cause to be deposited to the Distribution Account any amount not required to be
credited thereto, the Securities Administrator, upon receipt of a written
request therefor signed by a Servicing Officer of the Master Servicer, shall
promptly transfer such amount to the Master Servicer, any provision herein to
the contrary notwithstanding.

         (c) The Distribution Account shall constitute a trust account of the
Trust Fund segregated on the books of the Securities Administrator and held by
the Securities Administrator in trust in its Corporate Trust Office, and the
Distribution Account and the funds deposited therein shall not be subject to,
and shall be protected from, all claims, liens, and encumbrances of any
creditors or depositors of the Securities Administrator (whether made directly,
or indirectly through a liquidator or receiver of the Securities Administrator).
The amount at any time credited to the Distribution Account shall be invested in
the name of the Master Servicer, in such Eligible Investments selected by the
Master Servicer or deposited in demand deposits with such



                                      -63-
<PAGE>

depository institutions as selected by the Master Servicer, provided that time
deposits of such depository institutions would be an Eligible Investment. All
Eligible Investments shall mature or be subject to redemption or withdrawal on
or before, and shall be held until, the Distribution Date following the date of
the investment of such funds (the "Investment Withdrawal Distribution Date") if
the obligor for such Eligible Investment is the Securities Administrator or, if
such obligor is any other Person, the Business Day preceding such Investment
Withdrawal Distribution Date. All investment earnings on amounts on deposit in
the Distribution Account from time to time shall be for the account of the
Master Servicer. The Master Servicer shall be permitted to receive distribution
of any and all investment earnings from the Distribution Account on each
Distribution Date. If there is any loss on an Eligible Investment or demand
deposit, the Master Servicer shall deposit such amount in the Distribution
Account. With respect to the Distribution Account and the funds deposited
therein, the Securities Administrator shall take such action as may be necessary
to ensure that the Certificateholders shall be entitled to the priorities
afforded to such a trust account (in addition to a claim against the estate of
the Securities Administrator) as provided by 12 U.S.C. ss. 92a(e), and
applicable regulations pursuant thereto, if applicable, or any applicable
comparable state statute applicable to state chartered banking corporations.

         Section 3.24 Permitted Withdrawals and Transfers from the Distribution
Account.

         (a) The Securities Administrator shall, from time to time on demand of
the Master Servicer make or cause to be made such withdrawals or transfers from
the Distribution Account as the Master Servicer has designated for such transfer
or withdrawal pursuant to the Servicing Agreements for the following purposes,
not in any order of priority:

               (i) to reimburse the Master Servicer or any Servicer for any
          Advance of its own funds, the right of the Master Servicer or a
          Servicer to reimbursement pursuant to this subclause (i) being limited
          to amounts received on a particular Loan (including, for this purpose,
          the Purchase Price therefor, Insurance Proceeds and Liquidation
          Proceeds) which represent late payments or recoveries of the principal
          of or interest on such Loan respecting which such Advance was made;

               (ii) to reimburse the Master Servicer or any Servicer from
          Insurance Proceeds or Liquidation Proceeds relating to a particular
          Loan for amounts expended by the Master Servicer or such Servicer in
          good faith in connection with the restoration of the related Mortgaged
          Property which was damaged by an Uninsured Cause or in connection with
          the liquidation of such Loan;

               (iii) to reimburse the Master Servicer or any Servicer from
          Insurance Proceeds relating to a particular Loan for insured expenses
          incurred with respect to such Loan and to reimburse the Master
          Servicer or such Servicer from Liquidation Proceeds from a particular
          Loan for Liquidation Expenses incurred with respect to such Loan;

               (iv) to pay the Master Servicer or any Servicer, as appropriate,
          from Liquidation Proceeds or Insurance Proceeds received in connection
          with the liquidation of any Loan, the amount which it or such Servicer
          would have been entitled to receive under subclause (viii) of this
          Subsection (a) as servicing compensation on account of



                                      -64-
<PAGE>

          each defaulted scheduled payment on such Loan if paid in a timely
          manner by the related Mortgagor;

               (v) to pay the Master Servicer or any Servicer from the Purchase
          Price for any Loan, the amount which it or such Servicer would have
          been entitled to receive under subclause (x) of this Subsection (a) as
          servicing compensation;

               (vi) to reimburse the Master Servicer or any Servicer for any
          Nonrecoverable Advance, after a Realized Loss has been allocated with
          respect to the related Loan if the Advance or Servicing Advance has
          not been reimbursed pursuant to clause (i);

               (vii) to pay the Master Servicing Fee to the Master Servicer and
          the Credit Risk Management Fee to the Credit Risk Manager for such
          Distribution Date and the amount of any income or gain realized from
          investments of funds on deposit in the Distribution Account pursuant
          to Section 3.14 hereof and to reimburse the Master Servicer for
          expenses, costs and liabilities incurred by and reimbursable to it
          pursuant to Sections 3.3, 6.3, 8.5 and 10.1;

               (viii) to reimburse or pay any Servicer any such amounts as are
          due thereto under the applicable Servicing Agreement and have not been
          retained by or paid to the Servicer, to the extent provided in the
          related Servicing Agreement;

               (ix) to reimburse the Trustee, the Custodian and the Securities
          Administrator for expenses, costs and liabilities, if any, incurred by
          or reimbursable to such parties pursuant to this Agreement;

               (x) to remove amounts deposited in error; and

               (xi) to clear and terminate the Distribution Account pursuant to
          Section 9.1.

         (b) The Master Servicer shall keep and maintain separate accounting, on
a Loan by Loan basis, for the purpose of accounting for any reimbursement from
the Distribution Account pursuant to subclauses (i) through (v), inclusive, or
with respect to any such amounts which would have been covered by such
subclauses had the amounts not been retained by the Master Servicer without
being deposited in the Distribution Account under Section 3.23(b).

         (c) On each Distribution Date, the Securities Administrator shall
distribute the Available Distribution Amount to the Holders of the Certificates
in accordance with Section 4.1.

         Section 3.25 Reserve Fund.

         (a) No later than the Closing Date, the Securities Administrator shall
establish and maintain a separate, segregated trust account titled, "Reserve
Fund, Wells Fargo Bank Minnesota, National Association, in trust for the
registered holders of Deutsche Alt-A Securities, Inc. Mortgage Loan Trust,
Series 2003-4XS, Mortgage Pass-Through Certificates." On the Closing Date, the
Depositor will deposit, or cause to be deposited, into the Reserve Fund $1,000.

                                      -65-
<PAGE>

         (b) On each Distribution Date as to which there is a Net WAC Rate
Carryover Amount payable to the Class A Certificates or the Class M
Certificates, the Securities Administrator will deposit into the Reserve Fund
the amounts described in Section 4.1(a)(iii)(G), rather than distributing such
amounts to the Class CE Certificateholders. On each such Distribution Date, the
Securities Administrator shall hold all such amounts for the benefit of the
Holders of the Class A Certificates, other than the Class A-IO Certificates, and
the Class M Certificates, and will distribute such amounts to the Holders of the
Class A Certificates, other than the Class A-IO Certificates, and the Class M
Certificates in the amounts and priorities set forth in Section 4.1(a)(iii). If
no Net WAC Rate Carryover Amounts are payable on a Distribution Date, the
Securities Administrator shall deposit, based on the instructions received by it
from the Securities Administrator, into the Reserve Fund on behalf of the Class
CE Certificateholders, from amounts otherwise distributable to the Class CE
Certificateholders, an amount such that when added to other amounts already on
deposit in the Reserve Fund, the aggregate amount on deposit therein is equal to
$1,000.

         (c) For federal and state income tax purposes, the Class CE
Certificateholders will be deemed to be the owners of the Reserve Fund and all
amounts deposited into the Reserve Fund (other than the initial deposit therein
of $1,000) shall be treated as amounts distributed by REMIC III to the Holders
of the Class CE Certificates. Upon the termination of the Trust Fund, or the
payment in full of the Class A Certificates and the Class M Certificates, all
amounts remaining on deposit in the Reserve Fund will be released by the Trust
Fund and distributed to the Class CE Certificateholders or their designees. The
Reserve Fund will be part of the Trust Fund but not part of any REMIC and any
payments to the Holders of the Class A Certificates or the Class M Certificates
of Net WAC Rate Carryover Amounts will not be payments with respect to a
"regular interest" in a REMIC within the meaning of Code Section 860(G)(a)(1).

         (d) By accepting a Class CE Certificate, each Class CE
Certificateholder hereby agrees that the Securities Administrator will deposit
into the Reserve Fund the amounts described above on each Distribution Date
rather than distributing such amounts to the Class CE Certificateholders. By
accepting a Class CE Certificate, each Class CE Certificateholder further agrees
that its agreement to such action by the Securities Administrator is given for
good and valuable consideration, the receipt and sufficiency of which is
acknowledged by such acceptance.

         (e) The Securities Administrator shall direct any depository
institution maintaining the Reserve Fund to invest the funds in such account in
one or more Permitted Investments bearing interest or sold at a discount, and
maturing, unless payable on demand, (i) no later than the Business Day
immediately preceding the date on which such funds are required to be withdrawn
from such account pursuant to this Agreement, if a Person other than the
Securities Administrator or an Affiliate manages or advises such investment, and
(ii) no later than the date on which such funds are required to be withdrawn
from such account pursuant to this Agreement, if the Securities Administrator or
an Affiliate manages or advises such investment. All income and gain earned upon
such investment shall be deposited into the Reserve Fund. In no event shall the
Securities Administrator be liable for any investments made pursuant to this
clause (e).

                                      -66-
<PAGE>

         (f) For federal tax return and information reporting, the right of the
Class A Certificateholders and the Class M Certificateholders to receive
payments from the Reserve Fund in respect of any Net WAC Rate Carryover Amount
shall be assigned a value of zero.

         Section 3.26 Prepayment Penalty Verification.

         On or prior to each Servicer Remittance Date, each Servicer shall, to
the extent provided in the respective Servicing Agreement, provide in an
electronic format acceptable to the Master Servicer the data necessary for the
Master Servicer to perform its verification duties set forth in this Section
3.26. The Master Servicer or a third party reasonably acceptable to the Master
Servicer and the Depositor (the "Verification Agent") will perform such
verification duties and will use its best efforts to issue its findings in a
report (the "Verification Report") delivered to the Master Servicer and the
Depositor within ten (10) Business Days following the related Distribution Date;
provided, however, that if the Verification Agent is unable to issue the
Verification Report within ten (10) Business Days following the Distribution
Date, the Verification Agent may issue and deliver to the Master Servicer and
the Depositor the Verification Report upon the completion of its verification
duties. The Master Servicer shall forward the Verification Report to the
respective Servicer and shall notify such Servicer if the Master Servicer has
determined that such Servicer did not deliver the appropriate Prepayment Charges
to the Master Servicer in accordance with the respective Servicing Agreement.
Such written notification from the Master Servicer shall include the loan
number, prepayment penalty code and prepayment penalty amount as calculated by
the Master Servicer or the Verification Agent, as applicable, of each Loan for
which there is a discrepancy. If the respective Servicer agrees with the
verified amounts, such Servicer shall adjust the immediately succeeding
Remittance Report and the amount remitted to the Master Servicer with respect to
prepayments accordingly. If the respective Servicer disagrees with the
determination of the Master Servicer, such Servicer shall, within five (5)
Business Days of its receipt of the Verification Report, notify the Master
Servicer of such disagreement and provide the Master Servicer with detailed
information to support such Servicer's position. The respective Servicer and the
Master Servicer shall cooperate to resolve any discrepancy on or prior to the
immediately succeeding Servicer Remittance Date, and such Servicer will indicate
the effect of such resolution on the related Remittance Report and shall adjust
the amount remitted with respect to prepayments on such Servicer Remittance Date
accordingly.

         During such time as the respective Servicer and the Master Servicer are
resolving discrepancies with respect to the Prepayment Charges, no payments in
respect of any disputed Prepayment Charges will be remitted to the Distribution
Account and the Master Servicer shall not be obligated to remit such payments,
unless otherwise required pursuant to Section 7.01 hereof. In connection with
such duties, the Master Servicer shall be able to rely solely on the information
provided to it by the respective Servicer in accordance with this Section. The
Master Servicer shall not be responsible for verifying the accuracy of any of
the information provided to it by the respective Servicer.

next Distribution Date, the Securities Administrator shall, no later than the
Determination Date of the month of such Distribution Date, mail or cause to be
mailed to each Person in whose name a Certificate to be so retired is registered
at the close of business on the Record Date, to the Underwriter and to each
Rating Agency a notice to the effect that:

                                      -72-
<PAGE>

                    (i) it is expected that funds sufficient to make such final
               distribution shall be available in the Distribution Account on
               such Distribution Date, and

                    (ii) if such funds are available, (A) such final
               distribution shall be payable on such Distribution Date, but only
               upon presentation and surrender of such Certificate at the office
               or agency of the Securities Administrator maintained for such
               purpose (the address of which shall be set forth in such notice),
               and (B) no interest shall accrue on such Certificate after such
               Distribution Date.

         Section 4.2 Allocation of Realized Losses.

         Prior to each Distribution Date, the Master Servicer, based solely on
the information provided by the related Servicer, shall determine the amount of
Realized Losses, if any, with respect to each Loan.

         Realized Losses on the Loans for any Distribution Date will first,
cause a reduction in Net Monthly Excess Cash Flow for that Distribution Date and
second, cause a reduction in the Certificate Principal Balance of the Class CE
Certificates for that Distribution Date, until the Certificate Principal Balance
thereof has been reduced to zero. To the extent that Realized Losses on a
Distribution Date cause the aggregate Certificate Principal Balance of the
Offered Certificates after taking into account all distributions on such
Distribution Date to exceed the aggregate Principal Balance of the Mortgage
Loans as of the last day of the related Due Period, such excess will be
allocated first, to the Class M-3 Certificates; second, to the Class M-2
Certificates; and third, to the Class M-1 Certificates in each case to reduce
the Certificate Principal Balance thereof until it has been reduced to zero.

         Any allocation of Realized Losses to a Class M Certificate on any
Distribution Date shall be made by reducing the Certificate Principal Balance
thereof by the amount so allocated as of such Distribution Date after all
distributions on such Distribution Date have been made; any allocation of
Realized Losses to a Class CE Certificates shall be made by reducing the amount
otherwise payable in respect thereof pursuant to Section 4.1(a)(iii)(F). No
allocations of any Realized Losses shall be made to the Certificate Principal
Balances of the Senior Certificates or the Class P Certificates. Notwithstanding
anything to the contrary in this Agreement, in no event will the Certificate
Principal Balance of any Class M Certificate be reduced more than once in
respect of any particular amount both (i) allocable to the Class M Certificate
in respect of Realized Losses and (ii) payable as principal to the Holder of the
Certificate from Net Monthly Excess Cashflow.

         As used herein, an allocation of a Realized Loss on a "pro rata basis"
among two or more specified Classes of Certificates means an allocation on a pro
rata basis, among the various Classes so specified, to each such Class of
Certificates on the basis of their then outstanding Certificate Principal
Balances prior to giving effect to distributions to be made on such Distribution
Date. All Realized Losses and all other losses allocated to a Class of
Certificates hereunder will be allocated among the, Certificates of such Class
in proportion to the Percentage Interests evidenced thereby.

                  The principal portion of all Realized Losses on the Mortgage
Loans shall be allocated on each Distribution Date first, to REMIC I Regular
Interest LTI-1 and REMIC I

                                      -73-
<PAGE>

Regular Interest LTI-P, until the Uncertificated Principal Balances have been
reduced to zero and then to REMIC I Regular Interest LTI-IO-A, REMIC I Regular
Interest LTI-IO-B, REMIC I Regular Interest LTI-IO-C, REMIC I Regular Interest
LTI-IO-D, REMIC I Regular Interest LTI-IO-E and REMIC I Regular Interest
LTI-IO-F, until the Uncertificated Principal Balances have been reduced to zero.

                  All Realized Losses on the REMIC I Regular Interests shall be
allocated on each Distribution Date to the following REMIC II Regular Interests
in the specified percentages, as follows: first, to Uncertificated Accrued
Interest payable to the REMIC II Regular Interest LTII-AA and REMIC II Regular
Interest LTII-ZZ up to an aggregate amount equal to the REMIC II Interest Loss
Allocation Amount, 98% and 2%, respectively; second, to the Uncertificated
Principal Balances of the REMIC II Regular Interest LTII-AA and REMIC II Regular
Interest LTII-ZZ up to an aggregate amount equal to the REMIC II Principal Loss
Allocation Amount, 98% and 2%, respectively; third, to the Uncertificated
Principal Balances of REMIC II Regular Interest LTII-AA, 98%, to REMIC II
Regular Interest LTII-M3, 1% and to REMIC II Regular Interest LTII_ZZ, 1%,
respectively, until the Uncertificated Principal Balances of REMIC II Regular
Interest LTII-M3 has been reduced to zero; fourth, to the Uncertificated
Principal Balances of REMIC II Regular Interest LTII-AA, REMIC II Regular
Interest LTII-M2 and REMIC II Regular Interest LTII-ZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Principal Balance of REMIC II Regular
Interest LTII-M2 has been reduced to zero; and fifth, to the Uncertificated
Principal Balances of REMIC II Regular Interest LTII-AA, REMIC II Regular
Interest LTII-M1 and REMIC II Regular Interest LTII-ZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Principal Balance of REMIC II Regular
Interest LTII-M1 has been reduced to zero.

         Section 4.4 Advances.

         If the Monthly Payment on a Loan or a portion thereof is delinquent as
of its Due Date, other than as a result of interest shortfalls due to bankruptcy
proceedings or application of the Relief Act, and the related Servicer fails to
make an advance of the delinquent amount pursuant to the related Servicing
Agreement, the Master Servicer shall deposit in the Distribution Account, from
its own funds or from amounts on deposit in the Distribution Account that are
held for future distribution, not later than the Distribution Account Deposit
Date immediately preceding the related Distribution Date an amount equal to such
delinquency, net of the Servicing Fee and Master Servicing Fee for such Loan
except to the extent the Master Servicer determines any such advance to be
nonrecoverable from Liquidation Proceeds, Insurance Proceeds or future payments
on the Loan for which such Advance was made. Any amounts held for future
distribution and so used shall be appropriately reflected in the Master
Servicer's records and replaced by the Master Servicer by deposit in the
Distribution Account on or before any future Distribution Account Deposit Date
to the extent that the Available Distribution Amount for the related
Distribution Date (determined without regard to Advances to be made on the
Distribution Account Deposit Date) shall be less than the total amount that
would be distributed to the Classes of Certificateholders and MBIA pursuant to
Section 4.1 on such Distribution Date if such amounts held for future
distributions had not been so used to make Advances. Subject to the foregoing,
the Master Servicer shall continue to make such Advances through the date that
the related Servicer is required to do so under its Servicing Agreement. If
applicable, on the Distribution Account Deposit Date, the Master Servicer shall
present an Officer's Certificate to the Trustee and MBIA (i) stating that the
Master Servicer elects not to



                                      -77-

make an Advance in a stated amount and (ii) detailing the reason it deems the
advance to be nonrecoverable.

         Notwithstanding any other provision of this Agreement, the Trustee and
the Securities Administrator shall comply with all federal withholding
requirements respecting payments to Certificateholders of interest or original
issue discount that the Trustee and the Securities Administrator reasonably
believe are applicable under the Code. The consent of Certificateholders shall
not be required for such withholding. In the event the Securities Administrator
does withhold any amount from interest or original issue discount payments or
advances thereof to any Certificateholder pursuant to federal withholding
requirements, the Securities Administrator shall indicate the amount withheld to
such Certificateholders.

               Available Funds for such Distribution Date after the
               distributions made pursuant to clause (i) and clause (ii) above,
               first, to the Holders of REMIC I Regular Interest LTI-1 until the

                    (iv) to the Holders of the Class R Certificates, any amounts
               remaining after the distributions pursuant to clauses (i) through

               deferred when the REMIC II Overcollateralization Amount is less
               than the REMIC II Overcollateralization Target Amount, by the
               lesser of (x) the amount of such difference and (y) the REMIC II
               Regular Interest LTII-ZZ Maximum Interest Deferral Amount and
               such amount will be payable to the Holders of REMIC II Regular
               Interest LTII-A1, REMIC II Regular Interest LTII-A2, REMIC II

               Interest LTII-M1, REMIC II Regular Interest LTII-M2, REMIC II
               Regular Interest LTII-M3 in the same proportion as the
               Overcollateralization Increase Amount is allocated to the
               Corresponding Certificates, provided, however, that REMIC II
               Regular Interest LTII-ZZ is increased by such amount;

                    (ii) second, to the Holders of REMIC II Regular Interests,

Section 4.6       Policy Matters.

         (a) If, on the second Business Day before any Distribution Date, the
Securities Administrator determines that a Deficiency Amount exists on such
Distribution Date, the Securities Administrator shall give notice to MBIA and
the Fiscal Agent, if any, by telephone or telecopy of the amount of such
Deficiency Amount, confirmed in writing by notice substantially in the form of
Exhibit A to the Class A-6A Policy by 12:00 noon, New York City time on such
second Business Day.

         (b) In the event the Securities Administrator receives a certified copy
of an order of the appropriate court regarding any Preference Amount, the
Securities Administrator shall (i) promptly notify MBIA and the Fiscal Agent, if
any, and (ii) comply with the provisions of the Class A-6A Policy to obtain
payment by MBIA of such Preference Amount. In addition, the Securities
Administrator shall mail notice to all Holders of the Class A-6A Certificates so
affected that, in the event that any such Holder's scheduled payment is a
Preference Amount, such Holder will be entitled to payment pursuant to the terms
of the Class A-6A Policy, a copy of which shall be made available to such
Holders by the Securities Administrator. The Securities Administrator shall
furnish to MBIA and the Fiscal Agent, if any, its records listing the payments
on the affected Class A-6A Certificates, if any, that have been made by the
Securities



                                      -80-
<PAGE>



Administrator and subsequently recovered from the affected Holders, and the
dates on which such payments were made by the Securities Administrator.

         (c) At the time of the execution hereof, and for the purposes hereof,
the Securities Administrator shall establish a separate special purpose trust
account in the name of the Securities Administrator for the benefit of Holders
of the Class A-6A Certificates (the "Class A-6A Policy Payments Account") over
which the Securities Administrator shall have exclusive control and sole right
of withdrawal. The Class A-6A Policy Payments Account shall be an Eligible
Account. The Securities Administrator shall deposit any amount paid under the
Class A-6A Policy into the Class A-6A Policy Payments Account and distribute
such amount only for the purposes of making the payments to Holders of the Class
A-6A Certificates in respect of the Insured Payment (as defined in the Class
A-6A Policy) for which the related claim was made under the Class A-6A Policy.
Such amounts shall be allocated by the Securities Administrator to Holders of
Class A-6A Certificates affected by such shortfalls in the same manner as
interest and principal payments are to be allocated with respect to such
Certificates pursuant to Section 1.2 and Section 4.1. It shall not be necessary
for such payments to be made by checks or wire transfers separate from the
checks or wire transfers used to make regular payments hereunder with funds
withdrawn from the Distribution Account. However, any payments made on the Class
A-6A Certificates from funds in the Class A-6A Policy Payments Account shall be
noted as provided in subsection (e) below. Funds held in the Class A-6A Policy
Payments Account shall not be invested by the Securities Administrator.

         (d) Any funds received from MBIA for deposit into the Class A-6A Policy
Payments Account pursuant to the Class A-6A Policy in respect of a Distribution
Date or otherwise as a result of any claim under the Class A-6A Policy shall be
applied by the Securities Administrator directly to the payment in full (i) of
the Deficiency Amount due on such Distribution Date on the Class A-6A
Certificates, or (ii) of other amounts payable under the Class A-6A Policy.
Funds received by the Securities Administrator as a result of any claim under
the Class A-6A Policy shall be used solely for payment to the Holders of the
Class A-6A Certificates and may not be applied for any other purpose, including,
without limitation, satisfaction of any costs, expenses or liabilities of the
Trustee, the Securities Administrator, the Depositor, the Seller, any Servicer,
the Master Servicer or the Trust Fund. Any funds remaining in the Class A-6A
Policy Payments Account on the first Business Day after each Distribution Date
shall be remitted promptly to MBIA pursuant to the written instruction of MBIA.

         (e) The Securities Administrator shall keep complete and accurate
records in respect of (i) all funds remitted to it by MBIA and deposited into
the Class A-6A Policy Payments Account and (ii) the allocation of such funds to
(A) payments of interest on and principal in respect of any Class A-6A
Certificates and (B) the amount of funds available to make distributions on the
Class A-6A Certificates pursuant to Section 4.1. MBIA shall have the right to
inspect such records at reasonable times during normal business hours upon three
Business Days' prior notice to the Securities Administrator.

         (f) The Securities Administrator acknowledges, and each Holder of a
Class A-6A Certificate by its acceptance of the Class A-6A Certificate agrees,
that, without the need for any further action on the part of MBIA or the
Securities Administrator to the extent MBIA makes payments, directly or
indirectly, on account of principal of or interest on any Class A-6A

                                      -82-
<PAGE>

Certificates, MBIA will be fully subrogated to the rights of the Holders of such
Class A-6A Certificates to receive reimbursement of such principal and interest
from the Trust Fund. The Holders of the Class A-6A Certificates, by acceptance
of the Class A-6A Certificates, assign their rights as Holders of the Class A-6A
Certificates to the extent of MBIA's interest with respect to amounts paid under
the Class A-6A Policy. Anything herein to the contrary notwithstanding, solely
for purposes of determining MBIA's rights, as applicable, as subrogee for
payments distributable pursuant to Section 4.1, any payment with respect to
distributions to the Class A-6A Certificates which is made with funds received
pursuant to the terms of the Class A-6A Policy, shall not be considered payment
of the Class A-6A Certificates from the Trust Fund and shall not result in the
distribution or the provision for the distribution in reduction of the
Certificate Principal Balance of the Class A-6A Certificates as described in
this Article IV.

         (g) The Trustee, the Securities Administrator and the Master Servicer
shall cooperate in all respects with any reasonable request by MBIA for action
to preserve or enforce MBIA's rights or interests under this Agreement without
limiting the rights or affecting the interests of the Holders as otherwise set
forth herein.

         (h) [reserved]

         (i) The Trustee and the Securities Administrator shall promptly notify
MBIA of either of the following as to which a Responsible Officer of the Trustee
or authorized officer of the Securities Administrator has actual knowledge: (A)
the occurrence of a Master Servicer Event of Default or an "event of default"
under any Servicing Agreement, (B) the commencement of any proceeding by or
against the Depositor commenced under the United States bankruptcy code or any
other applicable bankruptcy, insolvency, receivership, rehabilitation or similar
law (an "Insolvency Proceeding") and (C) the making of any claim in connection
with any proceeding seeking the avoidance as a preferential transfer (a
"Preference Claim") of any distribution made with respect to the Class A-6A
Certificates as to which it has actual knowledge. Each Holder of a Class A-6A
Certificate, by its purchase of Class A-6A Certificates, the Trustee and the
Securities Administrator hereby agree that MBIA (so long as no MBIA Default
exists) may at any time during the continuation of any proceeding relating to a
Preference Claim direct all matters relating to such Preference Claim,
including, without limitation, (i) the direction of any appeal of any order
relating to any Preference Claim and (ii) the posting of any surety, supersedeas
or performance bond pending any such appeal. In addition and without limitation
of the foregoing, MBIA shall be subrogated to the rights of the Securities
Administrator and each Holder of a Class A-6A Certificate in the conduct of any
Preference Claim, including, without limitation, all rights of any party to an
adversary proceeding action with respect to any court order issued in connection
with any such Preference Claim.

         (j) The Master Servicer shall designate an MBIA Contact Person who
shall be available to MBIA to provide reasonable access to information
reasonably available to the Master Servicer regarding the Mortgage Loans. The
initial MBIA Contact Person is to the attention of Client Manager for Deutsche
Alt-A Securities, Inc. Mortgage Loan Trust, Series 2003-4XS, Mortgage
Pass-Through Certificates (410-884-2000).



                                      -82-

         (k) The Securities Administrator shall promptly surrender the Class
A-6A Policy to MBIA for cancellation upon the reduction of the Certificate
Principal Balance of the Class A-6A Certificates to zero.

         (l) The Securities Administrator shall send to MBIA any statements or
communications sent to Holders of the Class A-6A Certificates, in each case at
the same time such reports, statements and communications are otherwise sent.

         (m) For so long as there is not continuing default by MBIA under its
obligations under the Class A-6A Policy (an "MBIA Default"), each Holder of a
Class A-6A Certificate agrees that MBIA shall be treated by the Depositor, the
Master Servicer, the Securities Administrator and the Trustee as if MBIA were
the Holder of all Class A-6A Certificates for the purpose (and solely for the
purpose) of the giving of any consent, the making of any direction or the
exercise of any voting or other control rights otherwise given the Holders of
the Class A-6A Certificates hereunder without any further consent of the Holders
of the Class A-6A Certificates and such holders shall not exercise such rights
without the prior written consent of MBIA.

         (n) With respect to this Section 4.6, (i) the terms "Receipt" and
"Received" shall mean actual delivery to MBIA and MBIA's Fiscal Agent, if any,
received prior to 12:00 noon, New York City time, on a Business Day; delivery
either on a day that is not a Business Day or after 12:00 noon, New York City
time, shall be deemed to be Received on the next succeeding Business Day. If any
notice or certificate given under the Class A-6A Policy by the Securities
Administrator is not in proper form or is not properly completed, executed or
delivered, it shall be deemed not to have been Received. MBIA or its Fiscal
Agent, if any, shall promptly so advise the Securities Administrator and the
Securities Administrator may submit an amended notice and (ii) "Business Day"
means any day other than (A) a Saturday or Sunday, (B) a day on which MBIA is
closed or (C) a day on which banking institutions in the City of New York, New
York, or in which the Corporate Trust Office of the Trustee or the Securities
Administrator is located, are authorized or obligated by law or executive order
to be closed.

         (o) Unless otherwise designated in writing by the President or a
Managing Director of MBIA to the Securities Administrator, amounts payable to
MBIA pursuant to Section 4.1 shall be paid by the Securities Administrator to
MBIA by wire transfer with the following details specifically stated in the wire
transfer:

                                THE CERTIFICATES

Section 5.1       The Certificates.

         (a) Each of the Certificates shall be substantially in the forms
annexed hereto as exhibits, and shall, on original issue, be executed and
authenticated by the Securities Administrator and delivered by the Trustee to or
upon the receipt of a written order to authenticate from the Depositor
concurrently with the sale and assignment to the Trustee of the Trust Fund. The
Certificates shall be issuable in Authorized Denominations.

         The Certificates shall be executed by manual or facsimile signature on
behalf of the Trust Fund by a Responsible Officer of the Securities
Administrator. Certificates bearing the manual or facsimile signatures of
individuals who were, at the time such signatures were affixed, authorized to
sign on behalf of the Securities Administrator shall bind the Trust Fund,
notwithstanding that such individuals or any of them have ceased to be so
authorized prior to the authentication and delivery of such Certificates or did
not hold such offices at the date of such Certificate. No Certificate shall be
entitled to any benefit under this Agreement or be valid for any purpose, unless
such Certificate shall have been manually authenticated by the Securities
Administrator substantially in the form provided for herein, and such
authentication upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly authenticated and delivered
hereunder. All Certificates shall be dated the date of their authentication.
Subject to Section 5.3, the Class A Certificates and Class M Certificates shall
be Book-Entry Certificates. On the Closing Date, the Class CE, Class P and Class
R Certificates shall not be Book-Entry Certificates but shall be issued in fully
registered certificate form.

         (b) Neither the Trustee nor the Securities Administrator shall have any
liability to the Trust Fund and shall be indemnified by the Trust Fund for, any
cost, liability or expense incurred by them arising from a registration of a
Certificate or transfer, pledge sale or other disposition of a Certificate in
reliance upon a certification, Officer's Certificate, affidavit, ruling or
Opinion of Counsel described in this Article V.

         Section 5.2 Certificates Issuable in Classes; Distributions of
Principal and Interest; Authorized Denominations. The aggregate principal amount
of Certificates that may be authenticated and delivered under this Agreement is
limited to the aggregate Principal Balance of the Loans as of the Cut-Off Date,
as specified in the Preliminary Statement to this Agreement, except for
Certificates authenticated and delivered upon registration of transfer of, or in
exchange for, or in lieu of, other Certificates pursuant to Section 5.3. Such
aggregate principal amount shall be allocated among one or more Classes having
designations, types of interests, initial per annum Pass-Through Rates, initial
Class Principal Balances and last scheduled Distribution Dates as specified in
the Preliminary Statement to this Agreement. The aggregate Percentage Interest
of each Class of Certificates of which the Class Principal Balance equals zero
as of the Cut-Off Date that may be authenticated and delivered under this
Agreement is limited to 100%. Certificates shall be issued in Authorized
Denominations.

         Section 5.3 Registration of Transfer and Exchange of Certificates. (a)
The Securities Administrator shall cause to be kept at its Corporate Trust
Office a Certificate Register in which,



                                      -84-
<PAGE>

subject to such reasonable regulations as it may prescribe, the Securities
Administrator shall provide for the registration of Certificates and of
transfers and exchanges of Certificates as herein provided.

         Upon surrender for registration of transfer of any Certificate at the
Corporate Trust Office of the Securities Administrator maintained for such
purpose pursuant to the foregoing paragraph for certificate transfer and
surrender purposes, and, in the case of the Class CE Certificates, the Class P
Certificates or the Class R Certificates, upon satisfaction of the conditions
set forth in Sections 5.3(c), (d) and (e) below, as applicable, the Securities
Administrator on behalf of the Trust shall execute, authenticate and deliver, in
the name of the designated transferee or transferees, one or more new
Certificates of the same aggregate Percentage Interest.

         At the option of the Certificateholders, Certificates may be exchanged
for other Certificates in authorized denominations and the same aggregate
Percentage Interests, upon surrender of the Certificates to be exchanged at any
such office or agency. Whenever any Certificates are so surrendered for
exchange, the Securities Administrator shall execute, authenticate and deliver
the Certificates which the Certificateholder making the exchange is entitled to
receive. Every Certificate presented or surrendered for registration of transfer
or exchange shall (if so required by the Trustee or the Securities
Administrator) be duly endorsed by, or be accompanied by a written instrument of
transfer satisfactory to the Trustee and the Securities Administrator duly
executed by, the Holder thereof or his attorney duly authorized in writing.

         (a) Except as provided herein, the Book-Entry Certificates shall at all
times remain registered in the name of the Depository or its nominee and at all
times: (i) registration of such Certificates may not be transferred by the
Trustee or the Securities Administrator except to another Depository; (ii) the
Depository shall maintain book-entry records with respect to the Certificate
Owners and with respect to ownership and transfers of such Certificates; (iii)
ownership and transfers of registration of such Certificates on the books of the
Depository shall be governed by applicable rules established by the Depository;
(iv) the Depository may collect its usual and customary fees, charges and
expenses from its Depository Participants; (v) the Trustee and the Securities
Administrator shall for all purposes deal with the Depository as representative
of the Certificate Owners of the Certificates for purposes of exercising the
rights of Holders under this Agreement, and requests and directions for and
votes of such representative shall not be deemed to be inconsistent if they are
made with respect to different Certificate Owners; (vi) the Trustee and the
Securities Administrator may rely and shall be fully protected in relying upon
information furnished by the Depository with respect to its Depository
Participants and furnished by the Depository Participants with respect to
indirect participating firms and Persons shown on the books of such indirect
participating firms as direct or indirect Certificate Owners; and (vii) the
direct participants of the Depository shall have no rights under this Agreement
under or with respect to any of the Certificates held on their behalf by the
Depository, and the Depository may be treated by the Trustee, the Securities
Administrator and either the Trustee's or the Securities Administrator's agents,
employees, officers and directors as the absolute owner of the Certificates for
all purposes whatsoever.

         All transfers by Certificate Owners of Book-Entry Certificates shall be
made in accordance with the procedures established by the Depository Participant
or brokerage firm



                                      -85-
<PAGE>

representing such Certificate Owners. Each Depository Participant shall only
transfer Book-Entry Certificates of Certificate Owners that it represents or of
brokerage firms for which it acts as agent in accordance with the Depository's
normal procedures. The parties hereto are hereby authorized to execute a Letter
of Representations with the Depository or take such other action as may be
necessary or desirable to register a Book-Entry Certificate to the Depository.
In the event of any conflict between the terms of any such Letter of
Representation and this Agreement, the terms of this Agreement shall control.

         (b) If (i)(x) the Depository or the Depositor advises the Securities
Administrator in writing that the Depository is no longer willing or able to
discharge properly its responsibilities as Depository and (y) the Securities
Administrator or the Depositor is unable to locate a qualified successor, (ii)
the Depositor, at its sole option, with the consent of the Securities
Administrator, elects to terminate the book-entry system through the Depository
or (iii) after the occurrence of a Master Servicer Event of Default, the
Certificate Owners of the Book-Entry Certificates representing Percentage
Interests of such Classes aggregating not less than 66% advise the Securities
Administrator and Depository through the Depository Participants in writing that
the continuation of a book-entry system through the Depository is no longer in
the best interests of the Certificate Owners, the Securities Administrator shall
notify all Holders of Book-Entry Certificates of the occurrence of any such
event and of the availability of definitive, fully registered Certificates
("Definitive Certificates") to Certificate Owners requesting the same. Upon
surrender to the Securities Administrator of the Book-Entry Certificates by the
Depository, accompanied by registration instructions from the Depository for
registration, the Securities Administrator shall, at the Depositor's expense, in
the case of (i) and (ii) above, or the Master Servicer's expense, in the case of
(iii) above, execute on behalf of the Trust and authenticate the Definitive
Certificates. None of the Depositor, the Master Servicer, the Trustee or the
Securities Administrator 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, the Trustee,
the Securities Administrator, the Master Servicer and the Depositor shall
recognize the Holders of the Definitive Certificates as Certificateholders
hereunder.

         (c) No Transfer of a Class CE Certificate, Class P Certificate or Class
R Certificate shall be made unless such Transfer is made pursuant to an
effective registration statement under the Securities Act of 1933, as amended
(the "1933 Act") and any applicable state securities laws or is exempt from the
registration requirements under the 1933 Act and such state securities laws. In
the event of any such transfer in reliance upon an exemption from the 1933 Act
and such state securities laws, in order to assure compliance with the 1933 Act
and such state securities laws, the Certificateholder desiring to effect such
Transfer and such Certificateholder's prospective Transferee shall each certify
to the Trustee and the Securities Administrator in writing the facts surrounding
the Transfer in substantially the forms set forth in Exhibit D (the "Transferor
Certificate") and (x) deliver a letter in substantially the form of either
Exhibit E (the "Investment Letter") or Exhibit F (the "Rule 144A Letter") or (y)
there shall be delivered to the Trustee, the Depositor and the Securities
Administrator an Opinion of Counsel acceptable to and in form reasonably
satisfactory to the Trustee, the Depositor and the Securities Administrator that
such Transfer may be made pursuant to an exemption from the Securities Act,
which Opinion of Counsel shall not be an expense of the Depositor, the Seller,
the Master Servicer, the Securities Administrator or the Trustee. Each Holder of
a Class CE Certificate,



                                      -86-
<PAGE>

Class P Certificate or Class R Certificate desiring to effect such Transfer
shall, and does hereby agree to, indemnify the Trustee, the Depositor, the
Seller, the Securities Administrator and the Master Servicer against any
liability that may result if the Transfer is not so exempt or is not made in
accordance with such federal and state laws.

         (d) No transfer of a Class CE Certificate, Class P Certificate or Class
R Certificate or any interest therein shall be made to any Plan subject to ERISA
or Section 4975 of the Code (each, a "Plan"), any Person acting, directly or
indirectly, on behalf of any such Plan or any Person acquiring such Certificates
with "Plan Assets" of a Plan within the meaning of the Department of Labor
regulation promulgated at 29 C.F.R. ss. 2510.3-101 ("Plan Assets"), as certified
by each such Transferee in the form of Exhibit G, unless the Securities
Administrator is provided with an Opinion of Counsel for the benefit of the
Depositor, the Master Servicer, the Trustee, the Securities Administrator and
the Master Servicer and on which they may rely which establishes to the
satisfaction of each of them that the purchase of such Certificates is
permissible under applicable law, will not constitute or result in any
prohibited transaction under ERISA or Section 4975 of the Code and will not
subject the Depositor, the Master Servicer, the Trustee, the Securities
Administrator, any Servicer or the Trust Fund to any obligation or liability
(including obligations or liabilities under ERISA or Section 4975 of the Code)
in addition to those undertaken in this Agreement, which Opinion of Counsel
shall not be an expense of the Depositor, the Master Servicer, the Trustee, the
Securities Administrator or the Trust Fund. Neither a certification nor an
Opinion of Counsel will be required in connection with the initial transfer of
any such Certificate by the Depositor to an affiliate of the Depositor (in which
case, the Depositor or any affiliate thereof shall have deemed to have
represented that such affiliate is not a Plan or a Person investing Plan Assets)
and the Trustee and the Securities Administrator shall be entitled to
conclusively rely upon a representation (which, upon the request of the Trustee
or the Securities Administrator, shall be a written representation) from the
Depositor of the status of such transferee as an affiliate of the Depositor.

         Each Transferee of a Class M Certificate will be deemed to have
represented by virtue of its purchase or holding of such Certificate (or
interest therein) that either (a) such Transferee is not a Plan or purchasing
such Certificate with Plan Assets, (b) it has acquired and is holding such
Certificate in reliance on Prohibited Transaction Exemption ("PTE") 94-84 or FAN
97-03, as amended by PTE 97-34, 62 Fed. Reg. 39021 (July 21, 1997), PTE 2000-58,
65 Fed. Reg. 67765 (November 13, 2000) and PTE 2002-41 67 Fed. Reg. 54487
(August 22, 2002) (the "Exemption"), and that it understands that there are
certain conditions to the availability of the Exemption including that such
Certificate must be rated, at the time of purchase, not lower than "BBB-" (or
its equivalent) by a Rating Agency or (c) the following conditions are
satisfied: (i) such Transferee is an insurance company, (ii) the source of funds
used to purchase or hold such Certificate (or interest therein) is an "insurance
company general account" (as defined in U.S. Department of Labor Prohibited
Transaction Class Exemption ("PTCE") 95-60, and (iii) the conditions set forth
in Sections I and III of PTCE 95-60 have been satisfied.

         If any Class M Certificate, Class CE Certificate, Class P Certificate
or Class R Certificate or any interest therein is acquired or held in violation
of the provisions of this Section 5.3(d), the next preceding permitted
beneficial owner will be treated as the beneficial owner of that Certificate
retroactive to the date of transfer to the purported beneficial owner. Any
purported beneficial owner whose acquisition or holding of any such Certificate
or interest therein was



                                      -87-
<PAGE>

effected in violation of the provisions of the two preceding paragraphs shall
indemnify and hold harmless the Depositor, the Master Servicer, the Trustee, the
Securities Administrator and the Trust from and against any and all liabilities,
claims, costs or expenses incurred by those parties as a result of that
acquisition or holding.

         (e) Each Transferee of a Class R Certificate shall be deemed by the
acceptance or acquisition of the related Ownership Interest to have agreed to be
bound by the following provisions and to have irrevocably appointed the
Depositor or its designee as its attorney-in-fact to negotiate the terms of any
mandatory sale under clause (v) below and to execute all instruments of transfer
and to do all other things necessary in connection with any such sale, and the
rights of each Transferee of a Class R Certificate are expressly subject to the
following provisions:

          (i) Each such Transferee shall be a Permitted Transferee and shall
     promptly notify the Securities Administrator of any change or impending
     change in its status as a Permitted Transferee.

          (ii) No Person shall acquire an Ownership Interest in a Class R
     Certificate unless such Ownership Interest is a PRO RATA undivided
     interest.

          (iii) In connection with any proposed transfer of any Ownership
     Interest in a Class R Certificate, the Securities Administrator shall as a
     condition to registration of the transfer, require delivery to it, in form
     and substance satisfactory to it, of each of the following:

               (A) an affidavit in the form of Exhibit C hereto from the
          proposed Transferee to the effect that such Transferee is a Permitted
          Transferee and that it is not acquiring its Ownership Interest in the
          Class R Certificate that is the subject of the proposed transfer as a
          nominee, trustee or agent for any Person who is not a Permitted
          Transferee; and

               (B) a covenant of the proposed Transferee to the effect that the
          proposed Transferee agrees to be bound by and to abide by the transfer
          restrictions applicable to the Class R Certificates.

          (iv) Any attempted or purported transfer of any Ownership Interest in
     a Class R Certificate in violation of the provisions of this Section shall
     be absolutely null and void and shall vest no rights in the purported
     Transferee. If any purported Transferee shall, in violation of the
     provisions of this Section, become a Holder of a Class R Certificate, then
     the prior Holder of such Class R Certificate that is a Permitted Transferee
     shall, upon discovery that the registration of transfer of such Class R
     Certificate was not in fact permitted by this Section, be restored to all
     rights as Holder thereof retroactive to the date of registration of
     transfer of such Class R Certificate. The Securities Administrator shall be
     under no liability to any Person for any registration of transfer of a
     Class R Certificate that is in fact not permitted by this Section or for
     making any distributions due on such Class R 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 Securities Administrator
     received the documents specified in clause (iii).



                                      -88-
<PAGE>

The Securities Administrator shall be entitled to recover from any Holder of a
Class R Certificate that was in fact not a Permitted Transferee at the time such
distributions were made all distributions made on such Class R Certificate. Any
such distributions so recovered by the Securities Administrator shall be
distributed and delivered by the Securities Administrator to the prior Holder of
such Class R Certificate that is a Permitted Transferee.

          (v) If any Person other than a Permitted Transferee acquires any
     Ownership Interest in a Class R Certificate in violation of the
     restrictions in this Section, then the Securities Administrator shall have
     the right but not the obligation, without notice to the Holder of such
     Class R Certificate or any other Person having an Ownership Interest
     therein, to notify the Depositor to arrange for the sale of such Class R
     Certificate. The proceeds of such sale, net of commissions (which may
     include commissions payable to the Depositor or its affiliates in
     connection with such sale), expenses and taxes due, if any, will be
     remitted by the Securities Administrator to the previous Holder of such
     Class R Certificate that is a Permitted Transferee, except that in the
     event that the Securities Administrator determines that the Holder of such
     Class R Certificate may be liable for any amount due under this Section or
     any other provisions of this Agreement, the Securities Administrator may
     withhold a corresponding amount from such remittance as security for such
     claim. The terms and conditions of any sale under this clause (v) shall be
     determined in the sole discretion of the Securities Administrator and it
     shall not be liable to any Person having an Ownership Interest in a Class R
     Certificate as a result of its exercise of such discretion.

          (vi) If any Person other than a Permitted Transferee acquires any
     Ownership Interest in a Class R Certificate in violation of the
     restrictions in this Section, then the Securities Administrator upon
     receipt of reasonable compensation will provide to the Internal Revenue
     Service, and to the persons specified in Sections 860E(e)(3) and (6) of the
     Code, information needed to compute the tax imposed under Section
     860E(e)(5) of the Code on transfers of Class R interests to Disqualified
     Organizations.

         The foregoing provisions of this Section shall cease to apply to
transfers occurring on or after the date on which there shall have been
delivered to the Securities Administrator and MBIA, in form and substance
satisfactory to the Securities Administrator and MBIA, (i) written notification
from each Rating Agency that the removal of the restrictions on transfer set
forth in this Section will not cause such Rating Agency to downgrade its rating
of the Certificates and (ii) an Opinion of Counsel to the effect that such
removal will not cause any REMIC created hereunder to fail to qualify as a
REMIC. The Holder of the Class R Certificate issued hereunder, while not a
Disqualified Organization, is the Tax Matters Person.

         (f) No service charge shall be made for any registration of transfer or
exchange of Certificates of any Class, but the Securities Administrator may
require payment of a sum sufficient to cover any tax or governmental charge that
may be imposed in connection with any transfer or exchange of Certificates.

                                      -89-
<PAGE>

         All Certificates surrendered for registration of transfer or exchange
shall be canceled by the Securities Administrator and disposed of pursuant to
its standard procedures.

         Section 5.4 Mutilated, Destroyed, Lost or Stolen Certificates.

         If (i) any mutilated Certificate is surrendered to the Trustee or the
Securities Administrator, or (ii) the Trustee or the Securities Administrator
receives evidence to their satisfaction of the destruction, loss or theft of any
Certificate, and there is delivered to the Trustee and the Securities
Administrator (and, with respect to the Class A-6A Certificates, to MBIA) such
security or indemnity as may be required by them to save each of them harmless,
then, in the absence of notice to the Securities Administrator that such
Certificate has been acquired by a protected purchaser, the Securities
Administrator shall execute, authenticate and deliver, in exchange for or in
lieu of any such mutilated, destroyed, lost or stolen Certificate, a new
Certificate of like Percentage Interest. Upon the issuance of any new
Certificate under this Section 5.4, the Trustee or the Securities Administrator
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses connected therewith. Any replacement Certificate issued pursuant to
this Section 5.4 shall constitute complete and indefeasible evidence of
ownership in the Trust Fund, as if originally issued, whether or not the lost or
stolen Certificate shall be found at any time.

         Section 5.5 Persons Deemed Owners.

         The Depositor, the Securities Administrator, the Master Servicer, the
Trustee, MBIA and any agent of any of them may treat the Person in whose name
any Certificate is registered as the owner of such Certificate for the purpose
of receiving distributions pursuant to Section 4.1 and for all other purposes
whatsoever, and none of the Depositor, the Securities Administrator, the Master
Servicer, MBIA, the Trustee, or any agent of the Depositor, the Securities
Administrator, the Master Servicer, MBIA or the Trustee shall be affected by
notice to the contrary.

           THE DEPOSITOR, MASTER SERVICER AND THE CREDIT RISK MANAGER

         Section 6.1 Liability of the Depositor and the Master Servicer.

         The Depositor and the Master Servicer each shall be liable in
accordance herewith only to the extent of the obligations specifically imposed
by this Agreement upon them in their respective capacities as Depositor and
Master Servicer and undertaken hereunder by the Depositor and the Master
Servicer herein.

         Section 6.2 Merger or Consolidation of the Depositor or the Master
Servicer.

         Subject to the following paragraph, the Depositor shall keep in full
effect its existence, rights and franchises as a corporation under the laws of
the jurisdiction of its incorporation. Subject to the following paragraph, the
Master Servicer shall keep in full effect its existence, rights and franchises
as a corporation under the laws of the jurisdiction of its formation. The
Depositor and the Master Servicer each shall obtain and preserve its
qualification to do business as a foreign corporation in each jurisdiction in
which such qualification is or shall be necessary to protect the validity and
enforceability of this Agreement, the Certificates or any of the Loans and to
perform its respective duties under this Agreement.

         The Depositor or the Master Servicer may be merged or consolidated with
or into any Person, or transfer all or substantially all of its assets to any
Person, in which case any Person resulting from any merger or consolidation to
which the Depositor or the Master Servicer shall be a party, or any Person
succeeding to the business of the Depositor or the Master Servicer, shall be the
successor of the Depositor or the Master Servicer, as the case may be,
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto, anything herein to the contrary
notwithstanding; provided, however, the Rating Agencies' ratings of the
Certificates in effect immediately prior to such merger or consolidation will
not be qualified, reduced or withdrawn as a result thereof (as evidenced by a
letter to such effect from the Rating Agencies (determined without regard to the
Class A-6A Policy)).

         Section 6.3 Limitation on Liability of the Depositor, the Master
Servicer, the Servicers, the Securities Administrator and Others.

         None of the Depositor, the Master Servicer, the Securities
Administrator, the Servicers or any of the directors, officers, employees or
agents of the Depositor, the Master Servicer, the Securities Administrator or
the Servicers shall be under any liability to the Trust Fund or the
Certificateholders for any action taken or for refraining from the taking of any
action in good faith pursuant to this Agreement or the Servicing Agreements, or
for errors in judgment; provided, however, that this provision shall not protect
the Depositor, the Master Servicer, the Securities Administrator or any such
person against any breach of warranties, representations or covenants made
herein or in the Servicing Agreements, or against any specific liability imposed
on the Master Servicer, the Securities Administrator or the Servicers pursuant
hereto or pursuant to the Servicing Agreements, or against any liability which
would otherwise be imposed by reason of willful misfeasance, bad faith or gross
negligence in the performance of duties or by reason of reckless disregard of
obligations and duties hereunder or under the Servicing

                                      -91-
<PAGE>

Agreements. The Depositor, the Master Servicer, the Securities Administrator,
the Servicers and any director, officer, employee or agent of the Depositor, the
Master Servicer, the Securities Administrator or the Servicers may rely in good
faith on any document of any kind which, PRIMA FACIE, is properly executed and
submitted by any Person respecting any matters arising hereunder or under the
Servicing Agreements. The Depositor, the Master Servicer, the Servicers, the
Securities Administrator, the Custodian and any director, officer, employee or
agent of the Depositor, the Master Servicer, the Servicers, the Custodian or the
Securities Administrator shall be indemnified and held harmless by the Trust
Fund against any loss, liability or expense incurred in connection with any
legal action relating to this Agreement, the Certificates or any Servicing
Agreement, or any loss, liability or expense incurred by any of such Persons
other than by reason of such Person's willful misfeasance, bad faith or gross
negligence in the performance of its duties hereunder or by reason of reckless
disregard of its obligations and duties hereunder. None of the Depositor, the
Master Servicer, the Securities Administrator, the Custodian or any Servicer
shall be under any obligation to appear in, prosecute or defend any legal action
unless such action is related to its respective duties under this Agreement, the
Custodial Agreement or the applicable Servicing Agreement and, in its opinion,
does not involve it in any expense or liability; provided, however, that each of
the Depositor, the Master Servicer, the Custodian and the Securities
Administrator may in its discretion undertake any such action which it may deem
necessary or desirable with respect to this Agreement and the rights and duties
of the parties hereto and the interests of the Certificateholders hereunder. In
such event, the legal expenses and costs of such action and any liability
resulting therefrom (except any loss, liability or expense incurred by reason of
willful misfeasance, bad faith or gross negligence in the performance of duties
hereunder or by reason of reckless disregard of obligations and duties
hereunder) shall be expenses, costs and liabilities of the Trust Fund, and the
Depositor, the Master Servicer, the Custodian, the Servicers and the Securities
Administrator shall be entitled to be reimbursed therefor from the Distribution
Account as and to the extent provided in Article III, any such right of
reimbursement being prior to the rights of the Certificateholders to receive any
amount in the Distribution Account.

         Section 6.4 Limitation on Resignation of the Master Servicer.

         The Master Servicer shall not resign from the obligations and duties
hereby imposed on it except upon determination that its duties hereunder are no
longer permissible under applicable law. Any such determination pursuant to the
preceding sentence permitting the resignation of the Master Servicer shall be
evidenced by an Opinion of Counsel to such effect obtained at the expense of the
Master Servicer and delivered to the Trustee, MBIA and the Rating Agencies. No
resignation of the Master Servicer shall become effective until the Trustee or a
successor Master Servicer shall have assumed the Master Servicer's
responsibilities, duties, liabilities (other than those liabilities arising
prior to the appointment of such successor) and obligations under this
Agreement.

         Section 6.5 Assignment of Master Servicing.

         The Master Servicer may sell and assign its rights and delegate its
duties and obligations in its entirety as Master Servicer under this Agreement;
provided, however, that: (i) the purchaser or transferee accepting such
assignment and delegation (a) shall be a Person which shall be qualified to
service mortgage loans for Fannie Mae or Freddie Mac; (b) shall have a net worth
of

                                      -92-
<PAGE>

not less than $15,000,000 (unless otherwise approved by each Rating Agency
pursuant to clause (ii) below); (c) shall be reasonably satisfactory to the
Trustee (as evidenced in a writing signed by the Trustee); and (d) shall execute
and deliver to the Trustee an agreement, in form and substance reasonably
satisfactory to the Trustee, which contains an assumption by such Person of the
due and punctual performance and observance of each covenant and condition to be
performed or observed by it as master servicer under this Agreement, any
custodial agreement from and after the effective date of such agreement; (ii)
each Rating Agency and MBIA shall be given prior written notice of the identity
of the proposed successor to the Master Servicer and each Rating Agency's rating
of the Certificates in effect immediately prior to such assignment, sale and
delegation (determined without regard to the Class A-6A Policy) will not be
downgraded, qualified or withdrawn as a result of such assignment, sale and
delegation, as evidenced by a letter to such effect delivered to the Master
Servicer, MBIA and the Trustee; and (iii) the Master Servicer assigning and
selling the master servicing shall deliver to the Trustee and MBIA an officer's
certificate and an Opinion of Independent counsel, each stating that all
conditions precedent to such action under this Agreement have been completed and
such action is permitted by and complies with the terms of this Agreement. No
such assignment or delegation shall affect any liability of the Master Servicer
arising prior to the effective date thereof.

         Section 6.6 Rights of the Depositor in Respect of the Master Servicer.

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

         Section 6.7 Duties of the Credit Risk Manager.

         For and on behalf of the Depositor, pursuant to the Credit Risk
Management Agreements the Credit Risk Manager will provide reports and
recommendations concerning certain delinquent and defaulted Loans, and as to the
collection of any Prepayment Charges with respect to the Loans. Such reports and
recommendations will be based upon information provided to the Credit Risk
Manager pursuant to the related Credit Risk Management Agreement, and the Credit
Risk Manager shall look solely to the related Servicer for all information and
data (including loss and delinquency information and data) relating to the
servicing of the related Loans. Upon any termination of the Credit Risk Manager
or the appointment of a successor Credit Risk Manager, the Depositor shall give
written notice thereof to the Servicers, the Master Servicer, the Trustee, MBIA
and each Rating Agency. Notwithstanding the foregoing, the termination of the
Credit Risk Manager pursuant to this Section shall not become effective until
the appointment of a successor Credit Risk Manager.

         Section 6.8 Limitation Upon Liability of the Credit Risk Manager.

         Neither the Credit Risk Manager, nor any of its directors, officers,
employees, or agents shall be under any liability to the Trustee, the
Certificateholders, or the Depositor for any action taken or for refraining from
the taking of any action made in good faith pursuant to this Agreement, in
reliance upon information provided by a Servicer under a Credit Risk Management
Agreement, or for errors in judgment; provided, however, that this provision
shall not protect the Credit Risk Manager or any such person against liability
that would otherwise be imposed by reason of willful malfeasance or bad faith in
its performance of its duties. The Credit Risk Manager and any director,
officer, employee, or agent of the Credit Risk Manager may rely in good faith on
any document of any kind prima facie properly executed and submitted by any
Person respecting any matters arising hereunder, and may rely in good faith upon
the accuracy of information furnished by a Servicer pursuant to a Credit Risk
Management Agreement in the performance of its duties thereunder and hereunder.

         Section 6.9 Removal of the Credit Risk Manager.

         The Credit Risk Manager may be removed as Credit Risk Manager by
Certificateholders evidencing, in aggregate, not less than 66 2/3% of the
aggregate Percentage Interests of all Classes of Certificates, in the exercise
of its or their sole discretion. The Certificateholders shall provide written
notice of the Credit Risk Manager's removal to the Trustee. Upon receipt of such
notice, the Trustee shall provide written notice to the Credit Risk Manager of
its removal, which shall be effective upon receipt of such notice by the Credit
Risk Manager.

         Section 7.1 Master Servicer Events of Default.

         (a) "Master Servicer Event of Default," wherever used herein, means any
one of the following events:

          (i) [Reserved];

          (ii) any failure on the part of the Master Servicer duly to observe or
     perform in any material respect any other of the covenants or agreements on
     the part of the Master Servicer contained in this Agreement, or the breach
     by the Master Servicer of any representation and warranty contained in
     Section 2.5, which continues unremedied for a period of 30 days after the
     date on which written notice of such failure, requiring the same to be
     remedied, shall have been given to the Master Servicer by the Depositor or
     the Trustee or to the Master Servicer, the Depositor and the Trustee by the
     Holders of Certificates evidencing, in aggregate, not less than 25% of the
     Trust Fund; or

          (iii) a decree or order of a court or agency or supervisory authority
     having jurisdiction in the premises in an involuntary case under any
     present or future federal or state bankruptcy, insolvency or similar law or
     the appointment of a conservator or receiver or liquidator in any

     similar proceeding, or for the winding-up or liquidation of its affairs,
     shall have been entered against the Master Servicer and such decree or
     order shall have remained in force undischarged or unstayed for a period of
     90 days; or

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

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

          (vi) any failure of the Master Servicer to make any Advance on any
     Distribution Account Deposit Date required to be made from its own funds
     pursuant to Section 4.4 which continues unremedied until 3:00 p.m. New York
     time on the Business Day immediately following the Distribution Account
     Deposit Date.

         If a Master Servicer Event of Default described in clauses (ii) through
(v) of this Section shall occur, then, and in each and every such case, so long
as such Master Servicer Event of Default shall not have been remedied, the
Depositor or the Trustee may, and at the written direction of the Holders of
Certificates evidencing, in aggregate, not less than 51% of the Trust Fund, the

                                      -95-
<PAGE>

Trustee shall, by notice in writing to the Master Servicer (and to the Depositor
if given by the Trustee or to the Trustee if given by the Depositor) with a copy
to MBIA and each Rating Agency, terminate all of the rights and obligations of
the Master Servicer in its capacity as Master Servicer under this Agreement, to
the extent permitted by law, and in and to the Loans and the proceeds thereof.
Except as otherwise provided in Section 7.4, if a Master Servicer Event of
Default described in clause (vi) hereof shall occur, the Trustee shall, by
notice in writing to the Master Servicer, MBIA and the Depositor, terminate all
of the rights and obligations of the Master Servicer in its capacity as Master
Servicer under this Agreement and in and to the Loans and the proceeds thereof.
On or after the receipt by the Master Servicer of such written notice, all
authority and power of the Master Servicer under this Agreement, whether with
respect to the Certificates (other than as a Holder of any Certificate) or the
Loans or otherwise, shall pass to and be vested in the Trustee pursuant to and
under this Section, and, without limitation, the Trustee is hereby authorized
and empowered, as attorney-in-fact or otherwise, to execute and deliver, on
behalf of and at the expense of the Master Servicer, 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 Loans and related
documents, or otherwise. The Master Servicer agrees promptly (and in any event
no later than ten Business Days subsequent to such notice) to provide the
Trustee with all documents and records requested by it to enable it to assume
the Master Servicer's functions under this Agreement, and to cooperate with the
Trustee in effecting the termination of the Master Servicer's responsibilities
and rights under this Agreement (provided, however, that the Master Servicer
shall continue to be entitled to receive all amounts accrued or owing to it
under this Agreement on or prior to the date of such termination, whether in
respect of Advances or otherwise, and shall continue to be entitled to the
benefits of Section 6.3, notwithstanding any such termination, with respect to
events occurring prior to such termination). For purposes of this Section 7.1,
the Trustee shall not be deemed to have knowledge of a Master Servicer Event of
Default unless a Responsible Officer of the Trustee assigned to and working in
the Trustee's Corporate Trust Office has actual knowledge thereof or unless
written notice of any event which is in fact such a Master Servicer Event of
Default is received by the Trustee and such notice references the Certificates,
the Trust or this Agreement. The Trustee shall promptly notify MBIA and the
Rating Agencies of the occurrence of a Master Servicer Event of Default of which
it has knowledge as provided above.

         Section 7.2 Trustee to Act; Appointment of Successor.

         On and after the time the Master Servicer receives a notice of
termination, the Trustee shall be the successor in all respects to the Master
Servicer in its capacity as Master Servicer under this Agreement and the
transactions set forth or provided for herein, and all the responsibilities,
duties and liabilities relating thereto and arising thereafter shall be assumed
by the Trustee (except for any representations or warranties of the Master
Servicer under this Agreement, the responsibilities, duties and liabilities
contained in Section 2.3 and the obligation to deposit amounts in respect of
losses pursuant to Section 3.23(c)) by the terms and provisions hereof
including, without limitation, the Master Servicer's obligations to make
Advances no later than each Distribution Date pursuant to Section 4.4; provided,
however, that if the Trustee is prohibited by law or regulation from obligating
itself to make advances regarding delinquent mortgage loans, then the Trustee
shall not be obligated to make Advances pursuant to Section 4.4; and provided
further, that any failure to perform such duties or responsibilities caused by
the



                                      -96-
<PAGE>

Master Servicer's failure to provide information required by Section 7.1 shall
not be considered a default by the Trustee as successor to the Master Servicer
hereunder. As compensation therefor, the Trustee shall be entitled to the Master
Servicing Fee and all funds relating to the Loans, investment earnings on the
Distribution Account and all other remuneration to which the Master Servicer
would have been entitled if it had continued to act hereunder. Notwithstanding
the above and subject to the immediately following paragraph, the Trustee may,
if it shall be unwilling to so act, or shall, if it is unable to so act or if it
is prohibited by law from making advances regarding delinquent mortgage loans or
if the Holders of Certificates evidencing, in aggregate, not less than 51% of
the Trust Fund so request in writing promptly appoint or petition a court of
competent jurisdiction to appoint, an established mortgage loan servicing
institution acceptable to each Rating Agency and having a net worth of not less
than $15,000,000, as the successor to the Master Servicer under this Agreement
in the assumption of all or any part of the responsibilities, duties or
liabilities of the Master Servicer under this Agreement.

         No appointment of a successor to the Master Servicer under this
Agreement shall be effective until the assumption by the successor of all of the
Master Servicer's responsibilities, duties and liabilities hereunder. In
connection with such appointment and assumption described herein, the Trustee
may make such arrangements for the compensation of such successor out of
payments on Loans as it and such successor shall agree; provided, however, that
no such compensation shall be in excess of that permitted the Master Servicer as
such hereunder. The Depositor, the Trustee and such successor shall take such
action, consistent with this Agreement, as shall be necessary to effectuate any
such succession. Pending appointment of a successor to the Master Servicer under
this Agreement, the Trustee shall act in such capacity as hereinabove provided.
The transition costs and expenses incurred by the Trustee in connection with the
replacement of the Master Servicer shall be reimbursed out of the Trust.

         Section 7.3 Notification to Certificateholders.

         (a) Upon any termination of the Master Servicer pursuant to Section 7.1
above or any appointment of a successor to the Master Servicer pursuant to
Section 7.2 above, the Trustee shall give prompt written notice thereof to MBIA
and the Certificateholders at their respective addresses appearing in the
Certificate Register.

         (b) Not later than the later of 60 days after the occurrence of any
event, which constitutes or which, with notice or lapse of time or both, would
constitute a Master Servicer Event of Default or five days after a Responsible
Officer of the Trustee becomes aware of the occurrence of such an event, the
Trustee shall transmit by mail to MBIA and all Holders of Certificates notice of
each such occurrence, unless such default or Master Servicer Event of Default
shall have been cured or waived.

         Section 7.4 Waiver of Master Servicer Events of Default.

         The Holders evidencing, in aggregate, not less than 66 2/3% of the
aggregate Percentage Interests of all Classes of Certificates affected by any
default or Master Servicer Event of Default hereunder may waive such default or
Master Servicer Event of Default; provided, however, that a default or Master
Servicer Event of Default under clause (i) or (vi) of Section 7.1 may be waived
only by all of the Holders of the Regular Interest Certificates. Upon any such
waiver of a default or Master Servicer Event of Default, such default or Master
Servicer Event of Default



                                      -97-
<PAGE>

shall cease to exist and shall be deemed to have been remedied for every purpose
hereunder. No such waiver shall extend to any subsequent or other default or
Master Servicer Event of Default or impair any right consequent thereon except
to the extent expressly so waived. The Trustee shall give notice of any such
waiver to MBIA.

                                  ARTICLE VIII
             CONCERNING THE TRUSTEE AND THE SECURITIES ADMINISTRATOR

         Section 8.1 Duties of Trustee and Securities Administrator.

         The Trustee, prior to the occurrence of a Master Servicer Event of
Default and after the curing or waiver of all Master Servicer Events of Default
which may have occurred, and the Securities Administrator each undertake to
perform such duties and only such duties as are specifically set forth in this
Agreement as duties of the Trustee and the Securities Administrator,
respectively. During the continuance of a Master Servicer Event of Default, the
Trustee shall exercise such of the rights and powers vested in it by this
Agreement, and use the same degree of care and skill in its exercise as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs. Any permissive right of the Trustee enumerated in
this Agreement shall not be construed as a duty.

         Each of the Trustee and the Securities Administrator, upon receipt of
all resolutions, certificates, statements, opinions, reports, documents, orders
or other instruments furnished to it, which are specifically required to be
furnished pursuant to any provision of this Agreement, shall examine them to
determine whether they conform on their face to the requirements of this
Agreement. If any such instrument is found not to conform on its face to the
requirements of this Agreement, the Trustee or the Securities Administrator, as
the case may be, shall take such action as it deems appropriate to have the
instrument corrected, and if the instrument is not corrected to its
satisfaction, the Securities Administrator shall provide notice to the Trustee
thereof and the Trustee shall provide notice to the Certificateholders and MBIA.

         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 misconduct; provided, however, that:

          (i) Prior to the occurrence of a Master Servicer Event of Default, and
     after the curing or waiver of all such Master Servicer Events of Default
     which may have occurred with respect to the Trustee and at all times with
     respect to the Securities Administrator, the duties and obligations of the
     Trustee shall be determined solely by the express provisions of this
     Agreement, neither the Trustee nor the Securities Administrator shall be
     liable except for the performance of such duties and obligations as are
     specifically set forth in this Agreement, no implied covenants or
     obligations shall be read into this Agreement against the Trustee or the
     Securities Administrator and, in the absence of bad faith on the part of
     the Trustee or the Securities Administrator, respectively, the Trustee or
     the Securities Administrator, respectively, may conclusively rely, as to
     the truth of the statements and the correctness of the opinions expressed
     therein, upon any certificates or opinions furnished to the Trustee or the
     Securities Administrator, respectively, that conform to the requirements of
     this Agreement;

          (ii) Neither the Trustee nor the Securities Administrator shall be
     liable for an error of judgment made in good faith by a Responsible Officer
     or Responsible Officers of the Trustee or an officer or officers of the
     Securities Administrator,



                                      -99-
<PAGE>

     respectively, unless it shall be proved that the Trustee or the Securities
     Administrator, respectively, was negligent in ascertaining the pertinent
     facts; and

          (iii) Neither the Trustee nor the Securities Administrator shall be
     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 Holders of
     Certificates evidencing, in aggregate, not less than 25% of the Trust Fund
     relating to the time, method and place of conducting any proceeding for any
     remedy available to the Trustee or the Securities Administrator or
     exercising any trust or power conferred upon the Trustee or the Securities
     Administrator under this Agreement.

         Section 8.2 Certain Matters Affecting Trustee and Securities
Administrator.

         (a) Except as otherwise provided in Section 8.1:

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

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

          (iii) Neither the Trustee nor the Securities Administrator shall be
     under any obligation to exercise any of the trusts or powers vested in it
     by this Agreement or to institute, conduct or defend any litigation
     hereunder or in relation hereto at the request, order or direction of any
     of the Certificateholders, pursuant to the provisions of this Agreement,
     unless such Certificateholders shall have offered to the Trustee or the
     Securities Administrator, as the case may be, reasonable security or
     indemnity satisfactory to it against the costs, expenses and liabilities
     which may be incurred therein or thereby; nothing contained herein shall,
     however, relieve the Trustee of the obligation, upon the occurrence of a
     Master Servicer Event of Default (which has not been cured or waived), to
     exercise such of the rights and powers vested in it by this Agreement, and
     to use the same degree of care and skill in their exercise as a prudent
     person would exercise or use under the circumstances in the conduct of such
     person's own affairs;

          (iv) Neither the Trustee nor the Securities Administrator shall be
     liable for any action taken, suffered or omitted by it in good faith and
     believed by it to be authorized or within the discretion or rights or
     powers conferred upon it by this Agreement;



                                     -100-
<PAGE>

          (v) Prior to the occurrence of a Master Servicer Event of Default
     hereunder and after the curing or waiver of all Master Servicer Events of
     Default which may have occurred with respect to the Trustee and at all
     times with respect to the Securities Administrator, neither the Trustee nor
     the Securities Administrator shall be bound to make any investigation into
     the facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, consent, order, approval,
     bond or other paper or document, unless requested in writing to do so by
     the Holders of Certificates evidencing, in aggregate, not less than 25% of
     the Trust Fund; provided, however, that if the payment within a reasonable
     time to the Trustee or the Securities Administrator 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 or the Securities
     Administrator, as applicable, not reasonably assured to the Trustee or the
     Securities Administrator by such Certificateholders, the Trustee or the
     Securities Administrator, as applicable, may require reasonable indemnity
     satisfactory to it against such expense, or liability from such
     Certificateholders as a condition to taking any such action;

          (vi) The Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents or
     attorneys and the Trustee shall not be responsible for any misconduct or
     negligence on the part of any agent or attorney appointed with due care by
     it hereunder;

          (vii) The Securities Administrator shall not be liable for any loss
     resulting from the investment of funds held in the Distribution Account at
     the direction of the Master Servicer pursuant to Section 3.23(c);

          (viii) Neither the Trustee nor the Securities Administrator shall be
     liable for any action taken, suffered, or omitted to be taken by it in good
     faith and reasonably believed by it to be authorized or within the
     discretion or rights or powers conferred upon it by this Agreement;

          (ix) the Trustee shall not be deemed to have notice of any default or
     Master Servicer Event of Default 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 Certificates
     and this Agreement; and

          (x) the rights, privileges, protections, immunities and benefits given
     to the Trustee, including, without limitation, its right to be indemnified,
     are extended to, and shall be enforceable by, each agent, custodian and
     other Person employed to act hereunder.

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

         Section 8.3 Trustee and Securities Administrator not Liable for
Certificates or Loans.

         The recitals contained herein and in the Certificates (other than the
signature of the Securities Administrator, the authentication of the Securities
Administrator on the Certificates, the acknowledgments of the Trustee contained
in Article II and the representations and warranties of the Trustee in Section
8.12) shall be taken as the statements of the Depositor and neither the Trustee
nor the Securities Administrator assumes any responsibility for their
correctness. Neither the Trustee nor the Securities Administrator makes any
representations or warranties as to the validity or sufficiency of this
Agreement (other than as specifically set forth in Section 8.12) or of the
Certificates (other than the signature of the Securities Administrator and
authentication of the Securities Administrator on the Certificates) or of any
Loan or related document. The Trustee shall not be accountable for the use or
application by the Depositor of any of the Certificates or of the proceeds of
such Certificates, or for the use or application of any funds paid to the
Depositor or the Master Servicer in respect of the Loans or deposited in or
withdrawn from the Distribution Account.

         Section 8.4 Trustee and Securities Administrator May Own Certificates.

         Each of the Trustee and the Securities Administrator in its individual
capacity or any other capacity may become the owner or pledgee of Certificates
and may transact business with other interested parties and their Affiliates
with the same rights it would have if it were not Trustee or the Securities
Administrator.

         Section 8.5 Fees and Expenses of Trustee and Securities Administrator.

         The fees of the Trustee and the Securities Administrator hereunder and
of Wells Fargo under the Custodial Agreement shall be paid in accordance with a
side letter agreement with the Master Servicer and at the sole expense of the
Master Servicer. In addition, the Trustee, the Securities Administrator, the
Custodian and any director, officer, employee or agent of the Trustee, the
Securities Administrator and the Custodian shall be indemnified by the Trust and
held harmless against any loss, liability or expense (including reasonable
attorney's fees and expenses) incurred by the Trustee or the Securities
Administrator in connection with any default administration to be performed by
the Trustee or the Securities Administrator pursuant to this Agreement or other
agreements related hereto and any claim or legal action or any pending or
threatened claim or legal action arising out of or in connection with the
acceptance or administration of its respective obligations and duties under this
Agreement, including other agreements related hereto, other than any loss,
liability or expense (i) for which the Trustee is indemnified by the Master
Servicer, (ii) that constitutes a specific liability of the Trustee or the
Securities Administrator pursuant to Section 10.1(g) or (iii) any loss,
liability or expense incurred by reason of willful misfeasance, bad faith or
gross negligence in the performance of duties hereunder by reason of reckless
disregard of obligations and duties hereunder. The Master Servicer agrees to
indemnify the Trustee, from, and hold the Trustee harmless against, any loss,
liability or expense (including reasonable attorney's fees and expenses)
incurred by the Trustee by reason of the Master Servicer's willful misfeasance,
bad faith or gross negligence in the performance of its duties under this
Agreement or by reason of the Master Servicer's reckless disregard of its
obligations and duties under this Agreement. Such indemnity shall survive the
termination or discharge of this Agreement and the resignation or removal of the
Trustee. Any



                                     -102-
<PAGE>

payment hereunder made by the Master Servicer to the Trustee shall be from the
Master Servicer's own funds, without reimbursement from REMIC I therefor.

         Section 8.6 Eligibility Requirements for Trustee and Securities
Administrator.

         The Trustee and the Securities Administrator shall at all times be a
corporation or an association (other than the Depositor, the Seller, the Master
Servicer or any Affiliate of the foregoing) organized and doing business under
the laws of any state or the United States of America, authorized under such
laws to exercise corporate trust powers, having a combined capital and surplus
of at least $50,000,000 (or a member of a bank holding company whose capital and
surplus is at least $50,000,000) and subject to supervision or examination by
federal or state authority. If such corporation or association publishes reports
of conditions at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section the combined capital and surplus of such corporation or association
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of conditions so published. In case at any time the Trustee or the
Securities Administrator, as applicable, shall cease to be eligible in
accordance with the provisions of this Section, the Trustee or the Securities
Administrator, as applicable, shall resign immediately in the manner and with
the effect specified in Section 8.7.

         Section 8.7 Resignation and Removal of Trustee and Securities
Administrator.

         The Trustee and the Securities Administrator may at any time resign and
be discharged from the trust hereby created by giving written notice thereof to
the Depositor, to the Master Servicer, to the Securities Administrator (or the
Trustee, if the Securities Administrator resigns) and to the Certificateholders
with a copy to MBIA. Upon receiving such notice of resignation, the Depositor
shall promptly appoint a successor trustee or successor securities administrator
by written instrument, in duplicate, which instrument shall be delivered to the
resigning Trustee or Securities Administrator, as applicable, and to the
successor trustee or successor securities administrator, as applicable. A copy
of such instrument shall be delivered to the Certificateholders, the Trustee,
the Securities Administrator and the Master Servicer by the Depositor. If no
successor trustee or successor securities administrator shall have been so
appointed and have accepted appointment within 30 days after the giving of such
notice of resignation, the resigning Trustee or Securities Administrator, as the
case may be, may, at the expense of the Trust Fund, petition any court of
competent jurisdiction for the appointment of a successor trustee, successor
securities administrator, Trustee or Securities Administrator, as applicable.

         If at any time the Trustee or the Securities Administrator shall cease
to be eligible in accordance with the provisions of Section 8.6 and shall fail
to resign after written request therefor by the Depositor, or if at any time the
Trustee or the Securities Administrator shall become incapable of acting, or
shall be adjudged bankrupt or insolvent, or a receiver of the Trustee or the
Securities Administrator or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or the Securities
Administrator or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, then the Depositor may remove the Trustee or the
Securities Administrator, as applicable and appoint a successor trustee or
successor securities administrator, as applicable, by written instrument, in
duplicate, which instrument



                                     -103-
<PAGE>

shall be delivered to the Trustee or the Securities Administrator so removed and
to the successor trustee or successor securities administrator. A copy of such
instrument shall be delivered to MBIA, the Certificateholders, the Trustee, the
Securities Administrator and the Master Servicer by the Depositor.

         The Holders of Certificates evidencing, in aggregate, not less than 51%
of the Trust Fund may at any time remove the Trustee or the Securities
Administrator and appoint a successor trustee or successor securities
administrator by written instrument or instruments, in triplicate, signed by
such Holders or their attorneys-in-fact duly authorized, one complete set of
which instruments shall be delivered to the Depositor, one complete set to the
Trustee or the Securities Administrator so removed and one complete set to the
successor so appointed. A copy of such instrument shall be delivered to the
Certificateholders, the Trustee (in the case of the removal of the Securities
Administrator), the Securities Administrator (in the case of the removal of the
Trustee), MBIA and the Master Servicer by the Depositor. All costs and expenses
incurred by the Trustee in connection with its removal without cause hereunder
shall be reimbursed to it by the Trust Fund.

         Any resignation or removal of the Trustee or the Securities
Administrator and appointment of a successor trustee or successor securities
administrator pursuant to any of the provisions of this Section shall not become
effective until acceptance of appointment by the successor trustee or successor
securities administrator, as applicable, as provided in Section 8.8.

         Notwithstanding anything to the contrary contained herein, the Master
Servicer and the Securities Administrator shall at all times be the same Person.

         Section 8.8 Successor Trustee or Securities Administrator.

         Any successor trustee or successor securities administrator appointed
as provided in Section 8.7 shall execute, acknowledge and deliver to the
Depositor and its predecessor trustee or predecessor securities administrator an
instrument accepting such appointment hereunder, and thereupon the resignation
or removal of the predecessor trustee or predecessor securities administrator
shall become effective and such successor trustee or successor securities
administrator without any further act, deed or conveyance, shall become fully
vested with all the rights, powers, duties and obligations of its predecessor
hereunder, with the like effect as if originally named as trustee or securities
administrator herein. The predecessor trustee or predecessor securities
administrator shall deliver to the successor trustee or successor securities
administrator all Loan Documents and related documents and statements to the
extent held by it hereunder, as well as all moneys, held by it hereunder, and
the Depositor and the predecessor trustee or predecessor securities
administrator shall execute and deliver such instruments and do such other
things as may reasonably be required for more fully and certainly vesting and
confirming in the successor trustee or successor securities administrator all
such rights, powers, duties and obligations.

         No successor trustee or successor securities administrator shall accept
appointment as provided in this Section unless at the time of such acceptance
such successor trustee or successor securities administrator shall be eligible
under the provisions of Section 8.6 and the appointment of such successor
trustee or successor securities administrator shall not result in a downgrading



                                     -104-
<PAGE>

of any Class of Certificates by any Rating Agency (determined without regard to
the Class A-6A Policy), as evidenced by a letter from each Rating Agency.

         Upon acceptance of appointment by a successor trustee or successor
securities administrator as provided in this Section, the Depositor shall mail
notice of the succession of such trustee hereunder to MBIA and all Holders of
Certificates at their addresses as shown in the Certificate Register. If the
Depositor fails to mail such notice within 10 days after acceptance of
appointment by the successor trustee or successor securities administrator, the
successor trustee or successor securities administrator shall cause such notice
to be mailed at the expense of the Depositor.

         Section 8.9 Merger or Consolidation of Trustee or Securities
Administrator.

         Any corporation or association into which the Trustee or the Securities
Administrator may be merged or converted or with which it may be consolidated or
any corporation or association resulting from any merger, conversion or
consolidation to which the Trustee or the Securities Administrator shall be a
party, or any corporation or association succeeding to the business of the
Trustee or the Securities Administrator shall be the successor of the Trustee or
the Securities Administrator hereunder, provided such corporation or association
shall be eligible under the provisions of Section 8.6, without the execution or
filing of any paper or any further act on the part of any of the parties hereto,
anything herein to the contrary notwithstanding.

         Section 8.10 Appointment of Co-Trustee or Separate Trustee.

         Notwithstanding any other provisions hereof, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of REMIC I or property securing the same may at the time be located, the Trustee
shall have the power and shall execute and deliver all instruments to appoint
one or more Persons approved by the Trustee to act as co-trustee or co-trustees,
jointly with the Trustee, or separate trustee or separate trustees, of all or
any part of REMIC I, and to vest in such Person or Persons, in such capacity,
and for the benefit of the Holders of the Certificates and MBIA, such title to
REMIC I, or any part thereof, and, subject to the other provisions of this
Section 8.10, such powers, duties, obligations, rights and trusts as the Trustee
may consider necessary or desirable. No co-trustee or separate trustee hereunder
shall be required to meet the terms of eligibility as a successor trustee under
Section 8.6 hereunder and no notice to Holders of Certificates of the
appointment of co-trustee(s) or separate trustee(s) shall be required under
Section 8.8 hereof.

         In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 8.10 all 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 or co-trustee
jointly, except to the extent that under any law of any jurisdiction in which
any particular act or acts are to be performed by the Trustee (whether as
Trustee hereunder or as successor to a defaulting Master Servicer hereunder),
the Trustee shall be incompetent or unqualified to perform such act or acts, in
which event such rights, powers, duties and obligations (including the holding
of title to REMIC I or any portion thereof in any such jurisdiction) shall be
exercised and performed by such separate trustee or co-trustee at the direction
of the Trustee.

         Any notice, request or other writing given to the Trustee shall be
deemed to have been given to each of the then separate trustees and co-trustees,
as effectively as if given to each of them. Every instrument appointing any
separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article VIII. Each separate trustee and co-trustee, upon its acceptance
of the trust 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.

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

         Section 8.11 Appointment of Office or Agency.

         The Securities Administrator shall appoint an office or agency in the
City of Minneapolis located at Sixth and Marquette, Minneapolis, Minnesota
55479, where the Certificates may be surrendered for registration of transfer or
exchange, and presented for final distribution and where notices and demands to
or upon the Securities Administrator in respect of the Certificates and this
Agreement may be served.

         Section 8.12 Representations and Warranties of the Trustee.

         The Trustee hereby represents and warrants to the Master Servicer, the
Securities Administrator, MBIA and the Depositor as applicable, as of the
Closing Date, that:

          (i) It is a banking corporation duly organized, validly existing and
     in good standing under the laws of the State of New York.

          (ii) The execution and delivery of this Agreement by it, and the
     performance and compliance with the terms of this Agreement by it, will not
     violate its articles of incorporation or bylaws or constitute a default (or
     an event which, with notice or lapse of time, or both, would constitute a
     default) under, or result in the breach of, any material agreement or other
     instrument to which it is a party or which is applicable to it or any of
     its assets.

          (iii) It has the full power and authority to enter into and consummate
     all transactions contemplated by this Agreement, has duly authorized the
     execution, delivery and performance of this Agreement, and has duly
     executed and delivered this Agreement.

          (iv) This Agreement, assuming due authorization, execution and
     delivery by the other parties hereto, constitutes a valid, legal and
     binding obligation of it, enforceable against it in accordance with the
     terms hereof, subject to (A) applicable



                                     -106-
<PAGE>

     bankruptcy, insolvency, receivership, reorganization, moratorium and other
     laws affecting the enforcement of creditors' rights generally, and (B)
     general principles of equity, regardless of whether such enforcement is
     considered in a proceeding in equity or at law.

          (v) It is not in violation of, and its execution and delivery of this
     Agreement and its performance and compliance with the terms of this
     Agreement will not constitute a violation of, any law, any order or decree
     of any court or arbiter, or any order, regulation or demand of any federal,
     state or local governmental or regulatory authority, which violation, in
     its good faith and reasonable judgment, is likely to affect materially and
     adversely either the ability of it to perform its obligations under this
     Agreement or its financial condition.

          (vi) No litigation is pending or, to the best of its knowledge,
     threatened against it, which would prohibit it from entering into this
     Agreement or, in its good faith reasonable judgment, is likely to
     materially and adversely affect either the ability of it to perform its
     obligations under this Agreement or its financial condition.

                                   TERMINATION

         Section 9.1 Termination Upon Purchase or Liquidation of All Loans.

         (a) Subject to Section 9.2, the respective obligations and
responsibilities under this Agreement of the Depositor, the Master Servicer, the
Securities Administrator and the Trustee (other than the obligations of the
Master Servicer to the Securities Administrator pursuant to Section 8.5 and of
the Master Servicer to pay Compensating Interest to the Securities Administrator
and the Securities Administrator to make payments in respect of REMIC I Regular
Interests or the Classes of Certificates as hereinafter set forth) shall
terminate upon payment to the Certificateholders and the deposit of all amounts
held by or on behalf of the Trustee and required hereunder to be so paid or
deposited on the Distribution Date coinciding with or following the earlier to
occur of (i) the purchase by the Terminator (as defined below) of all Loans and
each REO Property remaining in REMIC I and (ii) the final payment or other
liquidation (or any advance with respect thereto) of the last Loan or REO
Property remaining in REMIC I; provided, however, that in no event shall the
trust 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, living on the date
hereof. The purchase by the Terminator of all Loans and each REO Property
remaining in REMIC I shall be at a price (the "Termination Price") equal to the
sum of (i) the aggregate Purchase Price of all the Loans included in REMIC I,
plus the fair market value of each REO Property, if any, included in REMIC I,
such valuation to be conducted by an appraiser mutually agreed upon by the
Terminator and the Securities Administrator in their reasonable discretion plus
(ii) any amounts due the Servicers and the Master Servicer in respect of unpaid
Servicing Fees, Master Servicing Fees and outstanding Advances and Servicing
Advances plus (iii) all MBIA Reimbursement Amounts due to MBIA.

         (b) The Master Servicer shall have the right (the party exercising such
right, the "Terminator"), to purchase all of the Loans and each REO Property
remaining in REMIC I pursuant to clause (i) of the preceding paragraph no later
than the Determination Date in the month immediately preceding the Distribution
Date on which the Certificates will be retired; provided, however, that the
Terminator may elect to purchase all of the Loans and each REO Property
remaining in REMIC I pursuant to clause (i) above only if the aggregate
Scheduled Principal Balance of the Loans and each REO Property remaining in the
Trust Fund at the time of such election is reduced to less than 10% of the
aggregate Scheduled Principal Balance of the Loans as of the Cut-Off Date.

         (c) Notice of the liquidation of the Certificates shall be given
promptly by the Securities Administrator by letter to MBIA and the
Certificateholders mailed (a) in the event such notice is given in connection
with the purchase of the Loans and each REO Property by the Terminator, not
earlier than the 15th day and not later than the 25th day of the month next
preceding the month of the final distribution on the Certificates or (b)
otherwise during the month of such final distribution on or before the
Determination Date in such month, in each case specifying (i) the Distribution
Date upon which the Trust Fund will terminate and the final



                                     -108-
<PAGE>

payment in respect of REMIC I Regular Interests or the Certificates will be made
upon presentation and surrender of the related Certificates at the office of the
Securities Administrator therein designated, (ii) the amount of any such final
payment, (iii) that no interest shall accrue in respect of REMIC I Regular
Interests or Certificates from and after the Interest Accrual Period relating to
the final Distribution Date therefor and (iv) that the Record Date otherwise
applicable to such Distribution Date is not applicable, payments being made only
upon presentation and surrender of the Certificates at the office of the
Securities Administrator. In the event such notice is given in connection with
the purchase of all of the Loans and each REO Property remaining in the REMIC I
by the Terminator, the Terminator shall deliver to the Securities Administrator
for deposit in the Distribution Account not later than the last Business Day of
the month next preceding the month of the final distribution on the Certificates
an amount in immediately available funds equal to the above-described
Termination Price. The Securities Administrator shall remit (a) to the Master
Servicer from such funds deposited in the Distribution Account (i) any amounts
which the Master Servicer notifies it in writing that the Master Servicer would
be permitted to withdraw and retain from the Distribution Account pursuant to
Section 3.24 and (ii) any other amounts otherwise payable by the Securities
Administrator to the Master Servicer from amounts on deposit in the Distribution
Account pursuant to the terms of this Agreement and notified by the Master
Servicer in writing and (b) to the Servicers, any amounts reimbursable to the
Servicers pursuant to the Servicing Agreements, in each case prior to making any
final distributions pursuant to Section 9.1(d) below. Upon certification to the
Trustee and the Securities Administrator by a Servicing Officer of the making of
such final deposit, the Trustee shall promptly release to the Terminator the
Mortgage Files for the remaining Loans, and the Trustee shall execute all
assignments, endorsements and other instruments necessary to effectuate such
transfer in each case without recourse, representation or warranty.

         (d) Upon presentation of the Certificates by the Certificateholders on
the final Distribution Date, the Securities Administrator shall distribute to
each Certificateholder so presenting and surrendering its Certificates the
amount otherwise distributable on such Distribution Date in accordance with
Section 4.1 in respect of the Certificates so presented and surrendered and
shall pay to MBIA on the final Distribution Date the amount of all outstanding
MBIA Reimbursement Amounts. Any funds not distributed to any Holder or Holders
of Certificates being retired on such Distribution Date because of the failure
of such Holder or Holders to tender their Certificates shall, on such date, be
set aside and held in trust and credited to the account of the appropriate
non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to this Section 9.1 shall not have been surrendered for
cancellation within six months after the time specified in such notice, the
Securities Administrator shall mail a second notice to the remaining
non-tendering Certificateholders to surrender their Certificates for
cancellation in order to receive the final distribution with respect thereto. If
within one year after the second notice all such Certificates shall not have
been surrendered for cancellation, the Securities Administrator shall, directly
or through an agent, mail a final notice to the remaining non-tendering
Certificateholders concerning surrender of their Certificates. The costs and
expenses of maintaining the funds in trust and of contacting such
Certificateholders shall be paid out of the assets remaining in the trust funds.
If within one year after the final notice any such Certificates shall not have
been surrendered for cancellation, the Securities Administrator shall pay to the
Depositor all such amounts, and all rights of non-tendering Certificateholders
in or to such amounts shall thereupon cease. No interest shall accrue or be
payable to any Certificateholder on any amount held in trust by the Securities



                                     -109-
<PAGE>

Administrator as a result of such Certificateholder's failure to surrender its
Certificate(s) for final payment thereof in accordance with this Section 9.1.
Any such amounts held in trust by the Securities Administrator shall be held in
an Eligible Account and the Securities Administrator may direct any depository
institution maintaining such account to invest the funds in one or more Eligible
Investments. All income and gain realized from the investment of funds deposited
in such accounts held in trust by the Securities Administrator shall be for the
benefit of the Securities Administrator; provided, however, that the Securities
Administrator shall deposit in such account the amount of any loss of principal
incurred in respect of any such Eligible Investment made with funds in such
accounts immediately upon the realization of such loss.

                  Immediately following the deposit of funds in trust hereunder
in respect of the Certificates, the Trust Fund shall terminate.

         Section 9.2 Additional Termination Requirements.

         (a) In the event that the Terminator purchases all the Loans and each
REO Property or the final payment on or other liquidation of the last Loan or
REO Property remaining in REMIC I pursuant to Section 9.1, the Trust Fund shall
be terminated in accordance with the following additional requirements:

          (i) The Securities Administrator shall specify the first day in the
     90-day liquidation period in a statement attached to each REMIC's final Tax
     Return pursuant to Treasury regulation Section 1.860F-1 and shall satisfy
     all requirements of a qualified liquidation under Section 860F of the Code
     and any regulations thereunder, as evidenced by an Opinion of Counsel
     obtained by and at the expense of the Terminator;

          (ii) During such 90-day liquidation period and, at or prior to the
     time of making of the final payment on the Certificates, the Securities
     Administrator shall sell all of the assets of REMIC I to the Terminator for
     cash; and

          (iii) At the time of the making of the final payment on the
     Certificates, the Securities Administrator shall distribute or credit, or
     cause to be distributed or credited, to the Holders of the Residual
     Certificates all cash on hand in the Trust Fund (other than cash retained
     to meet claims), and the Trust Fund shall terminate at that time.

         (b) At the expense of the requesting Terminator (or, if the Trust Fund
is being terminated as a result of the occurrence of the event described in
clause (ii) of the first paragraph of Section 9.1, at the expense of the Trust
Fund), the Terminator shall prepare or cause to be prepared the documentation
required in connection with the adoption of a plan of liquidation of each REMIC
pursuant to this Section 9.2.

         (c) By their acceptance of Certificates, the Holders thereof hereby
agree to authorize the Securities Administrator to specify the 90-day
liquidation period for each REMIC, which authorization shall be binding upon all
successor Certificateholders.

         Section 10.1 REMIC Administration.

         (a) The Trustee shall elect to treat each REMIC under the Code and, if
necessary, under applicable state law and as instructed by the Securities
Administrator. Each such election shall be made by the Securities Administrator
on Form 1066 or other appropriate federal tax or information return or any
appropriate state return for the taxable year ending on the last day of the
calendar year in which the Certificates are issued. For the purposes of the
REMIC election in respect of REMIC I, the REMIC I Regular Interests shall be
designated as the Regular Interests in REMIC I and the Class R-1 component shall
be designated as the Residual Interests in REMIC I. The REMIC II Regular
Interest shall be designated as the Regular Interests in REMIC II and the Class
R-2 component shall be designated as the Residual Interests in REMIC II. The
Certificates shall be designated as the Regular Interests in REMIC III and the
Class R-3 component shall be designated as the Residual Interests in REMIC III.
The Trustee shall not permit the creation of any "interests" in each Trust REMIC
(within the meaning of Section 860G of the Code) other than the REMIC I Regular
Interests, REMIC II Regular Interests and the interests represented by the
Certificates.

         (b) The Closing Date is hereby designated as the "Startup Day" of each
Trust REMIC within the meaning of Section 860G(a)(9) of the Code.

         (c) The Securities Administrator shall be reimbursed for any and all
expenses relating to any tax audit of the Trust Fund (including, but not limited
to, any professional fees or any administrative or judicial proceedings with
respect to each REMIC that involve the Internal Revenue Service or state tax
authorities), including the expense of obtaining any tax related Opinion of
Counsel except as specified herein. The Securities Administrator, as agent for
each REMIC's tax matters person shall (i) act on behalf of the Trust Fund in
relation to any tax matter or controversy involving any REMIC and (ii) 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 holder of the largest Percentage Interest of each class of Residual

301.6231(a)(7)-1, as the tax matters person of the related REMIC created
hereunder. By their acceptance thereof, the holder of the largest Percentage
Interest of the Residual Certificates hereby agrees to irrevocably appoint the
Securities Administrator or an Affiliate as its agent to perform all of the
duties of the tax matters person for the Trust Fund.

         (d) The Securities Administrator shall prepare and file and the Trustee
shall sign all of the Tax Returns in respect of each REMIC created hereunder.
The expenses of preparing and filing such returns shall be borne by the
Securities Administrator without any right of reimbursement therefor.

all reporting and other tax compliance duties that are the responsibility of
such REMIC under the Code, the REMIC Provisions or other compliance guidance
issued by the Internal Revenue



                                     -111-
<PAGE>

Service or any state or local taxing authority. Among its other duties, as
required by the Code, the REMIC Provisions or other such compliance guidance,
the Securities Administrator shall provide (i) to any Transferor of a Residual
Certificate such information as is necessary for the application of any tax
relating to the transfer of a Residual Certificate to any Person who is not a
Permitted Transferee upon receipt of additional reasonable compensation, (ii) to
the Certificateholders such information or reports as are required by the Code
or the REMIC Provisions including reports relating to interest, original issue
discount and market discount or premium (using the Prepayment Assumption as
required) and (iii) to the Internal Revenue Service the name, title, address and
telephone number of the person who shall serve as the representative of each
REMIC. The Depositor shall provide or cause to be provided to the Securities
Administrator, within ten (10) days after the Closing Date, all information or
data that the Securities Administrator reasonably determines to be relevant for
tax purposes as to the valuations and issue prices of the Certificates,
including, without limitation, the price, yield, prepayment assumption and
projected cash flow of the Certificates.

         (f) To the extent in the control of the Trustee or the Securities
Administrator, each such Person (i) shall take such action and shall cause each
REMIC created hereunder to take such action as shall be necessary to create or
maintain the status thereof as a REMIC under the REMIC Provisions, (ii) shall
not take any action, cause the Fund 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 (A) endanger the status of each Trust REMIC
as a REMIC or (B) result in the imposition of a tax upon the Trust Fund
(including but not limited to the tax on prohibited transactions as defined in
Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth
in Section 860G(d) of the Code) (either such event, an "Adverse REMIC Event")
unless such action or inaction is permitted under this Agreement or the Trustee,
MBIA and the Securities Administrator have received an Opinion of Counsel,
addressed to them (at the expense of the party seeking to take such action but
in no event at the expense of the Trustee, MBIA or the Securities Administrator)
to the effect that the contemplated action will not, with respect to any REMIC,
endanger such status or result in the imposition of such a tax, nor (iii) shall
the Securities Administrator take or fail to take any action (whether or not
authorized hereunder) as to which the Trustee has advised it in writing that it
has received an Opinion of Counsel to the effect that an Adverse REMIC Event
could occur with respect to such action; provided that the Securities
Administrator may conclusively rely on such Opinion of Counsel and shall incur
no liability for its action or failure to act in accordance with such Opinion of
Counsel. In addition, prior to taking any action with respect to any REMIC or
the respective assets of each, or causing any REMIC to take any action, which is
not contemplated under the terms of this Agreement, the Securities Administrator
shall consult with the Trustee or its designee, in writing, with respect to
whether such action could cause an Adverse REMIC Event to occur with respect to
any REMIC, and the Securities Administrator shall not 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. The Trustee may consult with
counsel to make such written advice, and the cost of same shall be borne by the
party seeking to take the action not permitted by this Agreement, but in no
event shall such cost be an expense of the Trustee.

         (g) In the event that any tax is imposed on "prohibited transactions"
of any REMIC created hereunder as defined in Section 860F(a)(2) of the Code, on
the "net income from



                                     -112-
<PAGE>

foreclosure property" of such REMIC as defined in Section 860G(c) of the Code,
on any contributions to any such REMIC after the Startup Day therefor pursuant
to Section 860G(d) of the Code, or any other tax is imposed by the Code or any
applicable provisions of state or local tax laws, such tax shall be charged (i)
to the Trustee pursuant to Section 10.3 hereof, if such tax arises out of or
results from a breach by the Trustee of any of its obligations under this
Article X, (ii) to the Securities Administrator pursuant to Section 10.3 hereof,
if such tax arises out of or results from a breach by the Securities
Administrator of any of its obligations under this Article X, (iii) to the
Master Servicer pursuant to Section 10.3 hereof, if such tax arises out of or
results from a breach by the Master Servicer of any of its obligations under
Article III or under this Article X, or (iv) against amounts on deposit in the
Distribution Account and shall be paid by withdrawal therefrom.

         (h) The Trustee and the Securities Administrator 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) Following the Startup Day, the Trustee shall not accept any
contributions of assets to any REMIC other than in connection with any
Substitute Loan delivered in accordance with Section 2.3 unless it and MBIA
shall have received an Opinion of Counsel addressed to it to the effect that the
inclusion of such assets in the Trust Fund will not cause the related REMIC to
fail to qualify as a REMIC at any time that any Certificates are outstanding or
subject such REMIC to any tax under the REMIC Provisions or other applicable
provisions of federal, state and local law or ordinances.

         (j) Neither the Trustee nor the Securities Administrator shall
knowingly enter into any arrangement by which any Trust REMIC will receive a fee
or other compensation for services nor permit either REMIC to receive any income
from assets other than "qualified mortgages" as defined in Section 860G(a)(3) of
the Code or "permitted investments" as defined in Section 860G(a)(5) of the
Code.

         (k) The Securities Administrator shall apply for an employer
identification number with the Internal Revenue Service via a Form SS-4 or other
comparable method for each REMIC. In connection with the foregoing, the
Securities Administrator shall provide the name and address of the person who
can be contacted to obtain information required to be reported to the holders of
Regular Interests in each REMIC as required by IRS Form 8811.

         Section 10.2 Prohibited Transactions and Activities.

         None of the Depositor, the Securities Administrator, the Master
Servicer or the Trustee shall sell, dispose of or substitute for any of the
Loans (except in connection with (i) the foreclosure of a Loan, including but
not limited to, the acquisition or sale of a Mortgaged Property acquired by deed
in lieu of foreclosure, (ii) the bankruptcy of REMIC I, (iii) the termination of
REMIC I pursuant to Article IX of this Agreement, (iv) a substitution pursuant
to Article II of this Agreement or (v) a purchase of Loans pursuant to Article
II of this Agreement), nor acquire any assets for any REMIC (other than REO
Property acquired in respect of a defaulted Loan), nor sell or dispose of any
investments in the Distribution Account for gain, nor accept any contributions
to any REMIC after the Closing Date (other than a Substitute Loan delivered in
accordance with Section 2.3), unless it and MBIA received an Opinion of Counsel,

                                     -113-
<PAGE>

addressed to the Trustee and MBIA (at the expense of the party seeking to cause
such sale, disposition, substitution, acquisition or contribution but in no
event at the expense of the Trustee or MBIA) that such sale, disposition,
substitution, acquisition or contribution will not (a) affect adversely the
status of any REMIC as a REMIC or (b) cause any REMIC to be subject to a tax on
"prohibited transactions" or "contributions" pursuant to the REMIC Provisions.

         Section 10.3 Indemnification.

         (a) The Trustee agrees to be liable for any taxes and costs incurred by
the Trust Fund, the Depositor, the Securities Administrator or the Master
Servicer including, without limitation, any reasonable attorneys fees imposed on
or incurred by the Trust Fund, the Depositor, the Securities Administrator or
the Master Servicer as a result of the Trustee's failure to perform its
covenants set forth in this Article X in accordance with the standard of care of
the Trustee set forth in this Agreement.

         (b) The Master Servicer agrees to indemnify the Trust Fund, the
Depositor and the Trustee for any taxes and costs including, without limitation,
any reasonable attorneys' fees imposed on or incurred by the Trust Fund, the
Depositor or the Trustee, as a result of the Master Servicer's failure to
perform its covenants set forth in Article III in accordance with the standard
of care of the Master Servicer set forth in this Agreement.

         (c) The Securities Administrator agrees to be liable for any taxes and
costs incurred by the Trust Fund, the Depositor or the Trustee including,
without limitation, any reasonable attorneys fees imposed on or incurred by the
Trust Fund, the Depositor or the Trustee as a result of the Securities
Administrator's failure to perform its covenants set forth in this Article X in
accordance with the standard of care of the Securities Administrator set forth
in this Agreement.

                            MISCELLANEOUS PROVISIONS

         Section 11.1 Amendment. This Agreement may be amended from time to time
by the Depositor, the Master Servicer, the Securities Administrator and the
Trustee, with the consent of MBIA but without the consent of any of the
Certificateholders, (a) to cure any ambiguity, to correct or supplement any
provision herein which may be inconsistent with any other provision herein, or
to make any other provisions with respect to matters or questions arising under
this Agreement, (b) to modify, eliminate or add to any provisions to such extent
as shall be necessary to maintain the qualification of the Trust Fund as three
REMICs at all times that any Class A Certificates or Class M Certificates, Class
CE Certificates or Class P Certificates are outstanding, provided, that such
action shall not, as evidenced by an Opinion of Counsel addressed to the Trustee
and delivered to the Trustee, adversely affect in any material respect the
interests of any Certificateholder (determined without regard to the Class A-6A
Policy). No amendment shall be deemed to adversely affect in any material
respect the interests of any Certificateholder who shall have consented thereto,
and no Opinion of Counsel shall be required to address the effect of any such
amendment on any such consenting Certificateholder.

         This Agreement may also be amended from time to time by the Depositor,
the Master Servicer, the Securities Administrator and the Trustee with the
consent of MBIA and the Holders of Certificates evidencing not less than 66-2/3%
of the aggregate Percentage Interests of all Classes of Certificates, for the
purpose of adding any provisions or changing in any manner or eliminating any of
the provisions of this Agreement or of modifying in any manner the rights of the
Holders of Certificates; provided, however, that no such amendment shall (a)
reduce in any manner the amount of, or delay the timing of, payments received on
Loans which are required to be distributed in respect of any Certificate without
the consent of the Holder of such Certificate; (b) adversely affect in any
material respect the interest of the Holders of the Class A Certificates in a
manner other than as described in (a) above without the consent of the Holders
of Class A Certificates aggregating not less than 66-2/3% of the aggregate
Percentage Interest evidenced by all Class A Certificates; (c) adversely affect
in any material respect the interest of the Holders of the Class M Certificates,
Class CE Certificates and Class P Certificates in a manner other than as
described in clause (a) above without the consent of the Holders of Class M
Certificates, Class CE Certificates and Class P Certificates aggregating not
less than 66-2/3% of the aggregate Percentage Interest evidenced by all such
Certificates; (d) adversely affect in any material respect the interest of the
Class R Certificateholder without the consent of the Holder of the Class R
Certificate; (e) change in any material respect the rights and obligations of
the Master Servicer or successor Master Servicer under this Agreement without
the prior written consent of such party; or (f) reduce the aforesaid percentage
of the Certificates the Holders of which are required to consent to any such
amendments without the consent of the Holders of all Certificates then
outstanding; provided, that for the purposes of this Agreement, the Holder of
the Class R Certificate shall have no right to vote at all times that any Class
A Certificates, Class M Certificates, Class CE Certificates or Class P
Certificates are outstanding if such amendment relates to the modification,
elimination or addition of any provision necessary to maintain the qualification
of the Trust Fund as three REMICs. Without limiting the generality of the
foregoing, any amendment to this Agreement required in connection with the
compliance with or



                                     -115-
<PAGE>

the clarification of any reporting obligations described in Section 3.18 hereof
shall not require the consent of any Certificateholder or MBIA or any Opinion of
Counsel or Rating Agency confirmation.

         Notwithstanding any contrary provision of this Agreement, the Trustee
shall not consent to any amendment to this Agreement unless it and MBIA shall
have first received an Opinion of Counsel addressed to it to the effect that
such amendment will not cause either REMIC I, REMIC II or REMIC III of the Trust
Fund to fail to qualify as a REMIC at any time that REMIC I Regular Interests,
REMIC II Regular Interests or Regular Interest Certificates are outstanding.

         As soon as practicable after the execution of any such amendment, the
Trustee shall furnish written notification of the substance of such amendment to
MBIA and each Certificateholder and Rating Agency.

         It shall not be necessary for the consent of the Certificateholders
under this Section 11.1 to approve the particular form of any proposed
amendment, but it shall be sufficient if such consent shall approve the
substance thereof. The manner of obtaining such consents and of evidencing the
authorization of the execution thereof by Certificateholders shall be subject to
such reasonable regulations as the Trustee may prescribe.

         Prior to the execution of any amendment to this Agreement, the Trustee
and MBIA shall be entitled to receive and rely upon an Opinion of Counsel
addressed to it stating that the execution of such amendment is authorized or
permitted by this Agreement. The Trustee may, but shall not be obligated to,
enter into any such amendment which affects the Trustee's own rights, duties or
immunities under this Agreement.

Section 11.2 Recordation of Agreement; Counterparts. To the extent permitted by
applicable law, this Agreement (or an abstract hereof, if acceptable by the
applicable recording office) is subject to recordation in all appropriate public
offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the properties subject to the Mortgages are
situated, and in any other appropriate public recording office or elsewhere,
such recordation to be effected by the Depositor at the expense of the
Certificateholders, but only after the Depositor has delivered to the Trustee an
Opinion of Counsel to the effect that such recordation materially and
beneficially affects the interests of the Certificateholders.

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

         Section 11.3 Limitation on Rights of Certificateholders. The death or
incapacity of any Certificateholder shall not operate to terminate this
Agreement or the Trust Fund, nor entitle such Certificateholder's legal
representatives or heirs to claim an accounting or take any action or proceeding
in any court for a partition or winding up of the 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 Certificateholder, shall have any right to
vote or in any manner otherwise control the



                                     -116-
<PAGE>

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.

         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 default
and of the continuance thereof, as hereinbefore provided, and unless all of the
Holders of Certificates evidencing, in aggregate, not less than 25% of the Trust
Fund 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 costs,
expenses and liabilities to be incurred therein or thereby, and the Trustee, for
60 days after its receipt of such notice, request and offer of indemnity, shall
have neglected or refused to institute any such action, suit or proceeding; it
being understood and intended, and being expressly covenanted by each
Certificateholder with every other Certificateholder and the Trustee, that no
one or more holders of Certificates shall have any right in any manner whatever
by virtue or by availing 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 11.3, each and every
Certificateholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

         Section 11.4 Governing Law. THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO CONFLICTS

         Section 11.8 Article and Section References.

         All article and section references used in this Agreement, unless
otherwise provided, are to articles and sections in this Agreement.

         Section 11.9 Grant of Security Interest.

         It is the express intent of the parties hereto that the conveyance of
the Loans by the Depositor to the Trustee, on behalf of the Trust Fund and for
the benefit of the Certificateholders, be, and be construed as, a sale of the
Loans by the Depositor and not a pledge of the Loans to secure a debt or other
obligation of the Depositor. However, in the event that, notwithstanding the
aforementioned intent of the parties, the Loans are held to be property of the
Depositor, then, (a) it is the express intent of the parties that such
conveyance be deemed a pledge of the Loans by the Depositor to the Trustee, on
behalf of the Trust Fund and for the benefit of the Certificateholders, to
secure a debt or other obligation of the Depositor and (b)(1) this Agreement
shall also be deemed to be a security agreement within the meaning of Articles 8
and 9 of the Uniform Commercial Code as in effect from time to time in the State
of New York; (2) the conveyance provided for in Section 2.1 hereof shall be
deemed to be a grant by the Depositor to the Trustee, on behalf of the Trust
Fund and for the benefit of the Certificateholders, of a security interest in
all of the Depositor's right, title and interest in and to the Loans and all
amounts payable to the holders of the Loans in accordance with the terms thereof
and all proceeds of the conversion, voluntary or involuntary, of the foregoing
into cash, instruments, securities or other property, including without
limitation all amounts, other than investment earnings, from time to time held
or invested in the Distribution Account, whether in the form of cash,
instruments, securities or other property; (3) the obligations secured by such
security agreement shall be deemed to be all of the Depositor's obligations
under this Agreement, including the obligation to provide to the
Certificateholders the benefits of this Agreement relating to the Loans and the
Trust Fund; and (4) notifications to persons holding such property, and
acknowledgments, receipts or confirmations from persons holding such property,
shall be deemed notifications to, or acknowledgments, receipts or confirmations
from, financial intermediaries, bailees or agents (as applicable) of the Trustee
for the purpose of perfecting such security interest under applicable law.
Accordingly, the Depositor hereby grants to the Trustee, on behalf of the Trust
Fund and for the benefit of the Certificateholders, a security interest in the
Loans and all other property described in clause (2) of the preceding sentence,
for the purpose of securing to the Trustee the performance by the Depositor of
the obligations described in clause (3) of the preceding sentence.
Notwithstanding the foregoing, the parties hereto intend the conveyance pursuant
to Section 2.1 to be a true, absolute and unconditional sale of the Loans and
assets constituting the Trust Fund by the Depositor to the Trustee, on behalf of
the Trust Fund and for the benefit of the Certificateholders.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

                  The Certificateholder, by its acceptance of this Certificate,
agrees that it will look solely to the Trust Fund for payment hereunder, and
that neither the Depositor, the Trustee, the Master Servicer nor the Securities

obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the

The Agreement also permits the amendment thereof, in certain limited
circumstances, without the consent of the Holders of any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable

Administrator for such purposes, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Securities Administrator duly
executed by the Holder hereof or such Holder's attorney duly authorized in

representing a like aggregate Percentage Interest will be issued to the
designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Securities Administrator may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith. The Depositor, the Master Servicer, the
Securities Administrator, the Trustee and any agent of any of them may treat the

none of Depositor, the Master Servicer, the Securities Administrator, the
Trustee or any such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the remittance of all funds due under the Agreement, coinciding
with or following the earlier to occur of (i) the maturity or other liquidation
(or Advance with respect thereto) of the last Mortgage Loan remaining in the
Trust Fund and disposition of all property acquired upon foreclosure or deed in
lieu of foreclosure of any Mortgage Loan or (ii) the optional repurchase by the
party named in the Agreement of all the Mortgage Loans and other assets of the
Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only on or after the Distribution Date on which the
aggregate Scheduled Principal Balance of the Mortgage Loans is less than the
percentage of the aggregate Scheduled Principal Balance specified in the
Agreement of the Mortgage Loans at the Cut-Off Date. The exercise of such right
will effect the early retirement of the Certificates. In no event, however, will
the Trust Fund created by the Agreement continue beyond the expiration of 21
years after the death of certain persons identified in the Agreement.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Securities Administrator by manual signature, this
Certificate shall not be entitled to any benefit under the Agreement, or be
valid for any purpose.

                                 SERIES 2003-4XS

         evidencing a fractional undivided interest in the distributions
         allocable to the Class [M]- [1][2][3] Certificates with respect
         to a Trust Fund consisting primarily of a pool of conventional
         one- to four-family fixed interest rate mortgage loans sold by
         DEUTSCHE ALT-A SECURITIES, INC.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Deutsche
Alt-A Securities, Inc., the Master Servicer, the Trustee or the Securities
Administrator referred to below or any of their affiliates or any other person.
Neither this Certificate nor the underlying Mortgage Loans are guaranteed or
insured by any governmental entity or by Deutsche Alt-A Securities, Inc., the
Master Servicer, the Trustee or the Securities Administrator or any of their
affiliates or any other person. None of Deutsche Alt-A Securities, Inc., the
Master Servicer or any of their affiliates will have any obligation with respect
to any certificate or other obligation secured by or payable from payments on
the Certificates.

                  This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced hereby in the beneficial ownership interest of
Certificates of the same Class as this Certificate in a trust (the "Trust Fund")
generally consisting of conventional first lien, fixed rate mortgage loans
secured by one- to four- family residences, units in planned unit developments
and individual condominium units (collectively, the "Mortgage Loans") sold by
Deutsche Alt-A Securities, Inc. ("DBALT"). The Mortgage Loans were sold by
Deutsche Bank AG New York Branch to DBALT. Wells Fargo Bank Minnesota, National
Association will act as master servicer of the Mortgage Loans (the "Master
Servicer," which term includes any successors thereto under the



                                     A-3-2
<PAGE>


Agreement referred to below). The Trust Fund was created pursuant to the Pooling
and Servicing Agreement dated as of the Cut-Off Date specified above (the
"Agreement"), among DBALT, as depositor (the "Depositor"), Wells Fargo Bank
Minnesota, National Association, as Master Servicer and securities administrator
(the "Securities Administrator") and HSBC Bank USA as trustee (the "Trustee"), a
summary of certain of the pertinent provisions of which is set forth hereafter.
To the extent not defined herein, capitalized terms used herein shall have the
meaning ascribed to them in the Agreement. This Certificate is issued under and
is subject to the terms, provisions and conditions of the Agreement, to which
Agreement the Holder of this Certificate by virtue of its acceptance hereof
assents and by which such Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Certificate Principal Balance hereof at a per annum rate equal to the
Pass-Through Rate set forth above. The Securities Administrator will distribute
on the 25th day of each month, or, if such 25th day is not a Business Day, the
immediately following Business Day (each, a "Distribution Date"), commencing on
the First Distribution Date specified above, to the Person in whose name this
Certificate is registered at the close of business on the last Business Day of
the calendar month preceding the month of such Distribution Date (the "Record
Date"), an amount equal to the product of the Percentage Interest evidenced by
this Certificate and the amount (of interest and principal, if any) required to
be distributed to the Holders of Certificates of the same Class as this
Certificate. The last scheduled Distribution Date is the Distribution Date in
October 2033.

                  Distributions on this Certificate will be made by the
Securities Administrator by wire transfer in immediately available funds to the
account of the Person in whose name the Certificate is registered at the close
of business on the related Record Date or by any other means of payment
acceptable to such Certificateholder. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the Securities
Administrator of the pendency of such distribution and only upon presentation
and surrender of this Certificate at the office or agency appointed by the
Securities Administrator for that purpose and designated in such notice. The
initial Certificate Principal Balance of this Certificate is set forth above.
The Certificate Principal Balance hereof will be reduced to the extent of
distributions allocable to principal hereon and any Realized Losses allocable
hereto as described in the Agreement.

                  Any transferee of this certificate shall be deemed to make the
representations set forth in section 5.3(d) of the Agreement.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

                  The Certificateholder, by its acceptance of this Certificate,
agrees that it will look solely to the Trust Fund for payment hereunder and that
neither the Depositor, the Trustee, the Master Servicer nor the Securities
Administrator is liable to the Certificateholders for any amount payable under
this Certificate or the Agreement or, except as expressly provided in the
Agreement, subject to any liability under the Agreement.

                  This Certificate does not purport to summarize the Agreement
and reference is made to the Agreement for the interests, rights and limitations
of rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Securities Administrator.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of Certificates affected thereby evidencing not less than 66-2/3% of the
Voting Rights. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, without the consent of the Holders of any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Securities Administrator upon surrender of this Certificate for
registration of transfer at the offices or agencies maintained by the Securities
Administrator for such purposes, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Securities Administrator duly
executed by the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Certificates in authorized denominations
representing a like aggregate Percentage Interest will be issued to the
designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Securities Administrator may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith. The Depositor, the Master Servicer, the
Trustee, the Securities Administrator and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner hereof for all
purposes, and none of the Depositor, the Master Servicer, the Trustee, the
Securities Administrator or any such agent shall be affected by notice to the
contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the remittance of all funds due under the Agreement, coinciding
with or following the earlier to occur of (i) the maturity or other liquidation
(or Advance with respect thereto) of the last Mortgage Loan remaining in the
Trust Fund and disposition of all property acquired upon foreclosure or deed in
lieu of foreclosure of any Mortgage Loan or (ii) the optional repurchase by the
party named in the Agreement of all the Mortgage Loans and other assets of the
Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only on or after the Distribution Date on which the
aggregate Scheduled Principal Balance of the Mortgage Loans is less than the
percentage of the aggregate Scheduled Principal Balance specified



                                     A-3-4

in the Agreement of the Mortgage Loans at the Cut-Off Date. The exercise of such
right will effect the early retirement of the Certificates. In no event,
however, will the Trust Fund created by the Agreement continue beyond the
expiration of 21 years after the death of certain persons identified in the
Agreement.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Securities Administrator by manual signature, this
Certificate shall not be entitled to any benefit under the Agreement, or be
valid for any purpose.

Agreement dated as of the Cut-Off Date specified above (the "Agreement"), among

certain of the pertinent provisions of which is set forth hereafter. To the
extent not defined herein, capitalized terms used herein shall have the meaning
ascribed to them in the Agreement. This Certificate is issued under and is
subject to the terms, provisions and conditions of the Agreement, to which
Agreement the Holder of this Certificate by virtue of its acceptance hereof
assents and by which such Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Certificate Principal Balance hereof at a per annum rate equal to the
Pass-Through Rate set forth above. The Securities Administrator will distribute
on the 25th day of each month, or, if such 25th day is not a Business Day, the
immediately following Business Day (each, a "Distribution Date"), commencing on
the First Distribution Date specified above, to the Person in whose name this
Certificate is registered at the close of business on the last Business Day of
the calendar month preceding the month of such Distribution Date (the "Record
Date"), an amount equal to the product of the Percentage Interest evidenced by
this Certificate and the amount (of interest and principal, if any) required to
be distributed to the Holders of Certificates of the same Class as this
Certificate. The last scheduled Distribution Date is the Distribution Date in
October 2033.

                  Distributions on this Certificate will be made by the
Securities Administrator by wire transfer in immediately available funds to the
account of the Person in whose name the Certificate is registered at the close
of business on the related Record Date or by any other means of payment

Administrator of the pendency of such distribution and only upon presentation

The Certificate Principal Balance hereof will be reduced to the extent of
distributions allocable to principal hereon and certain losses allocable hereto
as described in the Agreement.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Securities Administrator shall require
receipt of (i) if such transfer is purportedly being made in reliance upon Rule
144A under the 1933 Act, written certifications from the Holder of the
Certificate desiring to effect the transfer, and from such Holder's prospective
transferee, substantially in the forms attached to the Agreement as Exhibit D
and either Exhibit E or Exhibit F, as applicable, and (ii) in all other cases,
an Opinion of Counsel reasonably satisfactory to the Trustee, the Depositor and
the Securities Administrator that such transfer may be made without such
registration or qualification (which Opinion of Counsel shall not be an expense
of the Trust Fund or of the Depositor, the Trustee, the Securities
Administrator, the Master Servicer, any Servicer or the Trust Fund in their
respective capacities as such), together with copies of the written
certification(s) of the Holder of the Certificate desiring to effect the
transfer and/or such Holder's prospective transferee upon which such Opinion of
Counsel is based. None of



                                     A-4-3
<PAGE>


the Depositor, the Securities Administrator or the Trustee is obligated to
register or qualify the Class of Certificates specified on the face hereof under
the 1933 Act or any other securities law or to take any action not otherwise
required under the Agreement to permit the transfer of such Certificates without
registration or qualification. Any Holder desiring to effect a transfer of this
Certificate shall be required to indemnify the Trustee, the Securities
Administrator, the Depositor, the Seller and the Master Servicer against any
liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

                  No transfer of this Class CE Certificate will be made unless
the Depositor, the Trustee and the Securities Administrator have received either
(i) an opinion of counsel under Section 5.3(d) of the Agreement stating, among
other things, that the transferee's acquisition of a Class CE Certificate is
permissible under applicable law, will not constitute or result in a non-exempt
prohibited transaction under Section 406 of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA") or Section 4975 of the Internal
Revenue Code (the "Code") and will not subject the Depositor, the Trustee, the
Securities Administrator, the Master Servicer, any Servicer or the Trust Fund to
any obligation or liability in addition to those undertaken in the Agreement or
(ii) a representation letter, in the form as described by the Agreement, stating
that the transferee is not an employee benefit or other plan subject to the
prohibited transaction provisions of ERISA or Section 4975 of the Code (a
"Plan"), or any other person (including an investment manager, a named fiduciary
or a trustee of any Plan) acting, directly or indirectly, on behalf of or
purchasing any Certificate with "plan assets" of any Plan.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

                  The Certificateholder, by its acceptance of this Certificate,
agrees that it will look solely to the Trust Fund for payment hereunder and that
neither the Trustee nor the Securities Administrator is liable to the
Certificateholders for any amount payable under this Certificate or the
Agreement or, except as expressly provided in the Agreement, subject to any
liability under the Agreement.

                  This Certificate does not purport to summarize the Agreement
and reference is made to the Agreement for the interests, rights and limitations
of rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Securities Administrator.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of Certificates affected thereby evidencing not less than 66-2/3% of the
Voting Rights. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, without the consent of the Holders of any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Securities Administrator upon surrender of this Certificate



                                     A-4-4
<PAGE>


for registration of transfer at the offices or agencies maintained by the
Securities Administrator for such purposes, duly endorsed by, or accompanied by
a written instrument of transfer in form satisfactory to the Securities
Administrator duly executed by the Holder hereof or such Holder's attorney duly
authorized in writing, and thereupon one or more new Certificates in authorized
denominations representing a like aggregate Percentage Interest will be issued
to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Securities Administrator may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith. The Depositor, the Master Servicer, the
Trustee, the Securities Administrator and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner hereof for all
purposes, and none of the Depositor, the Master Servicer, the Trustee, the
Securities Administrator or any such agent shall be affected by notice to the
contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the remittance of all funds due under the Agreement, coinciding
with or following the earlier to occur of (i) the maturity or other liquidation
(or Advance with respect thereto) of the last Mortgage Loan remaining in the
Trust Fund and disposition of all property acquired upon foreclosure or deed in
lieu of foreclosure of any Mortgage Loan or (ii) the optional repurchase by the
party named in the Agreement of all the Mortgage Loans and other assets of the
Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only on or after the Distribution Date on which the
aggregate Scheduled Principal Balance of the Mortgage Loans is less than the
percentage of the aggregate Scheduled Principal Balance specified in the
Agreement of the Mortgage Loans at the Cut-Off Date. The exercise of such right
will effect the early retirement of the Certificates. In no event, however, will
the Trust Fund created by the Agreement continue beyond the expiration of 21
years after the death of certain persons identified in the Agreement.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Securities Administrator by manual signature, this
Certificate shall not be entitled to any benefit under the Agreement, or be

         evidencing a fractional undivided interest in the distributions
         allocable to the Class P Certificates with respect to a Trust
         Fund consisting primarily of a pool of conventional one- to
         four-family fixed interest rate mortgage loans sold by DEUTSCHE
         ALT-A SECURITIES, INC.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Deutsche
Alt-A Securities, Inc., the Master Servicer, the Trustee or the Securities
Administrator referred to below or any of their affiliates or any other person.
Neither this Certificate nor the underlying Mortgage Loans are guaranteed or
insured by any governmental entity or by Deutsche Alt-A Securities, Inc., the
Master Servicer, the Trustee or the Securities Administrator or any of their
affiliates or any other person. None of Deutsche Alt-A Securities, Inc., the
Master Servicer or any of their affiliates will have any obligation with respect
to any certificate or other obligation secured by or payable from payments on
the Certificates.

                  This certifies that [______________] is the registered owner
of the Percentage Interest evidenced hereby in the beneficial ownership interest
of Certificates of the same Class as this Certificate in a trust (the "Trust
Fund") generally consisting of conventional first lien, fixed rate mortgage
loans secured by one- to four- family residences, units in planned unit
developments and individual condominium units (collectively, the "Mortgage
Loans") sold by Deutsche Alt-A Securities, Inc. ("DBALT"). The Mortgage Loans
were sold by Deutsche Bank AG New York Branch to DBALT. Wells Fargo Bank
Minnesota, National Association will act as master servicer of the Mortgage
Loans (the "Master Servicer," which term includes any successors thereto under
the



                                     A-5-2
<PAGE>


Agreement referred to below). The Trust Fund was created pursuant to the
Pooling and Servicing Agreement dated as of the Cut-Off Date specified above
(the "Agreement"), among DBALT, as depositor (the "Depositor"), Wells Fargo Bank
Minnesota, National Association, as Master Servicer and securities administrator
(the "Securities Administrator") and HSBC Bank USA as trustee (the "Trustee"), a
summary of certain of the pertinent provisions of which is set forth hereafter.
To the extent not defined herein, capitalized terms used herein shall have the
meaning ascribed to them in the Agreement. This Certificate is issued under and
is subject to the terms, provisions and conditions of the Agreement, to which
Agreement the Holder of this Certificate by virtue of its acceptance hereof
assents and by which such Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 25th day of each month or, if such 25th day is not a Business Day,
the Business Day immediately following such 25th day (a "Distribution Date"),
commencing on the First Distribution Date specified above, to the Person in
whose name this Certificate is registered on the last Business Day of the
calendar month immediately preceding the month in which the related Distribution
Date occurs (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class P Certificates on such Distribution Date
pursuant to the Agreement.

                  The Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than the distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans.

                  Distributions on this Certificate will be made by the
Securities Administrator by wire transfer in immediately available funds to the
account of the Person in whose name the Certificate is registered at the close
of business on the related Record Date or by any other means of payment
acceptable to such Certificateholder. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the Securities
Administrator of the pendency of such distribution and only upon presentation
and surrender of this Certificate at the office or agency appointed by the
Securities Administrator for that purpose and designated in such notice. The
initial Certificate Principal Balance of this Certificate is set forth above.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Securities Administrator shall require
receipt of (i) if such transfer is purportedly being made in reliance upon Rule
144A under the 1933 Act, written certifications from the Holder of the
Certificate desiring to effect the transfer, and from such Holder's prospective
transferee, substantially in the forms attached to the Agreement as Exhibit D
and either Exhibit E or Exhibit F, as applicable, and (ii) in all other cases,
an Opinion of Counsel reasonably satisfactory to the Trustee, the Depositor and
the Securities Administrator that such transfer may be made without such
registration or qualification (which Opinion of Counsel shall not be an expense
of the Trust Fund or of the Depositor, the Trustee, the Securities
Administrator,



                                     A-5-3
<PAGE>


the Master Servicer, any Servicer or the Trust Fund in their respective
capacities as such), together with copies of the written certification(s) of the
Holder of the Certificate desiring to effect the transfer and/or such Holder's
prospective transferee upon which such Opinion of Counsel is based. None of the
Depositor, the Securities Administrator or the Trustee is obligated to register
or qualify the Class of Certificates specified on the face hereof under the 1933
Act or any other securities law or to take any action not otherwise required
under the Agreement to permit the transfer of such Certificates without
registration or qualification. Any Holder desiring to effect a transfer of this
Certificate shall be required to indemnify the Trustee, the Securities
Administrator, the Depositor, the Seller and the Master Servicer against any
liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

                  No transfer of this Class P Certificate will be made unless
the Depositor, the Trustee and the Securities Administrator have received either
(i) an opinion of counsel under Section 5.3(d) of the Agreement stating, among
other things, that the transferee's acquisition of a Class P Certificate is
permissible under applicable law, will not constitute or result in a non-exempt
prohibited transaction under Section 406 of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA") or Section 4975 of the Internal
Revenue Code (the "Code") and will not subject the Depositor, the Trustee, the
Securities Administrator, the Master Servicer any Servicer or the Trust Fund to
any obligation or liability in addition to those undertaken in the Agreement or
(ii) a representation letter, in the form as described by the Agreement, stating
that the transferee is not an employee benefit or other plan subject to the
prohibited transaction provisions of ERISA or Section 4975 of the Code (a
"Plan"), or any other person (including an investment manager, a named fiduciary
or a trustee of any Plan) acting, directly or indirectly, on behalf of or
purchasing any Certificate with "plan assets" of any Plan.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

                  The Certificateholder, by its acceptance of this Certificate,
agrees that it will look solely to the Trust Fund for payment hereunder and that
neither the Trustee nor the Securities Administrator is liable to the
Certificateholders for any amount payable under this Certificate or the
Agreement or, except as expressly provided in the Agreement, subject to any
liability under the Agreement.

                  This Certificate does not purport to summarize the Agreement
and reference is made to the Agreement for the interests, rights and limitations
of rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Securities Administrator.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of Certificates affected thereby evidencing not less than 66-2/3% of the
Voting Rights. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, without the consent of the Holders of any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Securities Administrator upon surrender of this Certificate for
registration of transfer at the offices or agencies maintained by the Securities
Administrator for such purposes, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Securities Administrator duly
executed by the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Certificates in authorized denominations
representing a like aggregate Percentage Interest will be issued to the
designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Depositor, the Master Servicer, the Securities Administrator, the
Trustee and any agent of any of them may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Master Servicer, the Securities Administrator, the Trustee or any
such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the remittance of all funds due under the Agreement, coinciding
with or following the earlier to occur of (i) the maturity or other liquidation
(or Advance with respect thereto) of the last Mortgage Loan remaining in the
Trust Fund and disposition of all property acquired upon foreclosure or deed in
lieu of foreclosure of any Mortgage Loan or (ii) the optional repurchase by the
party named in the Agreement of all the Mortgage Loans and other assets of the
Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only on or after the Distribution Date on which the
aggregate Scheduled Principal Balance of the Mortgage Loans is less than the
percentage of the aggregate Scheduled Principal Balance specified in the
Agreement of the Mortgage Loans at the Cut-Off Date. The exercise of such right
will effect the early retirement of the Certificates. In no event, however, will
the Trust Fund created by the Agreement continue beyond the expiration of 21
years after the death of certain persons identified in the Agreement.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Securities Administrator by manual signature, this
Certificate shall not be entitled to any benefit under the Agreement, or be
valid for any purpose.

                                     A-6-3
<PAGE>


Agreement dated as of the Cut-Off Date specified above (the "Agreement"), among
DBALT, as depositor (the "Depositor"), Wells Fargo Bank Minnesota, National
Association, as Master Servicer and securities administrator (the "Securities
Administrator") and HSBC Bank USA as trustee (the "Trustee"), a summary of
certain of the pertinent provisions of which is set forth hereafter. To the
extent not defined herein, capitalized terms used herein shall have the meaning
ascribed to them in the Agreement. This Certificate is issued under and is
subject to the terms, provisions and conditions of the Agreement, to which
Agreement the Holder of this Certificate by virtue of its acceptance hereof
assents and by which such Holder is bound.

                  Each Holder of this Certificate will be deemed to have agreed
to be bound by the restrictions set forth in the Agreement to the effect that
(i) each person holding or acquiring any Ownership Interest in this Certificate
must be a United States Person and a Permitted Transferee, (ii) the transfer of
any Ownership Interest in this Certificate will be conditioned upon the delivery
to the Securities Administrator of, among other things, an affidavit to the
effect that it is a United States Person and Permitted Transferee, (iii) any
attempted or purported transfer of any Ownership Interest in this Certificate in
violation of such restrictions will be absolutely null and void and will vest no
rights in the purported transferee, and (iv) if any person other than a United
States Person and a Permitted Transferee acquires any Ownership Interest in this
Certificate in violation of such restrictions, then the Depositor will have the
right, in its sole discretion and without notice to the Holder of this
Certificate, to sell this Certificate to a purchaser selected by the Depositor,
which purchaser may be the Depositor, or any affiliate of the Depositor, on such
terms and conditions as the Depositor may choose.

                  The Securities Administrator will distribute on the 25th day
of each month, or, if such 25th day is not a Business Day, the immediately
following Business Day (each, a "Distribution Date"), commencing on the First
Distribution Date specified above, to the Person in whose name this Certificate
is registered at the close of business on the last Business Day of the calendar
month immediately preceding the month in which such Distribution Date occurs
(the "Record Date"), an amount equal to the product of the Percentage Interest
evidenced by this Certificate and the amounts required to be distributed to the
Holders of Certificates of the same Class as this Certificate. The last
scheduled Distribution Date is the Distribution Date in October 2033.

                  Distributions on this Certificate will be made by the
Securities Administrator by wire transfer in immediately available funds to the
account of the Person in whose name the Certificate is registered at the close
of business on the related Record Date or by any other means of payment
acceptable to such Certificateholder. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the Securities
Administrator of the pendency of such distribution and only upon presentation
and surrender of this Certificate at the office or agency appointed by the
Securities Administrator for that purpose and designated in such notice.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Securities Administrator shall require
receipt of (i) if such transfer is purportedly being made in reliance upon Rule
144A under the 1933 Act, written certifications from the Holder of the
Certificate desiring to effect the transfer, and



                                     A-6-4
<PAGE>


from such Holder's prospective transferee, substantially in the forms attached
to the Agreement as Exhibit D and either Exhibit E or Exhibit F, as applicable,
and (ii) in all other cases, an Opinion of Counsel satisfactory to it that such
transfer may be made without such registration or qualification (which Opinion
of Counsel shall not be an expense of the Trust Fund or of the Depositor, the
Trustee, the Securities Administrator or the Master Servicer in their respective
capacities as such), together with copies of the written certification(s) of the
Holder of the Certificate desiring to effect the transfer and/or such Holder's
prospective transferee upon which such Opinion of Counsel is based. None of the
Depositor, the Securities Administrator or the Trustee is obligated to register
or qualify the Class of Certificates specified on the face hereof under the 1933
Act or any other securities law or to take any action not otherwise required
under the Agreement to permit the transfer of such Certificates without
registration or qualification. Any Holder desiring to effect a transfer of this
Certificate shall be required to indemnify the Trustee, the Securities
Administrator, the Depositor, the Seller and the Master Servicer against any
liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

                  No transfer of this Class R Certificate will be made unless
the Depositor, the Trustee and the Securities Administrator have received either
(i) an opinion of counsel under Section 5.3(d) of the Agreement stating, among
other things, that the transferee's acquisition of a Class R Certificate is
permissible under applicable law, will not constitute or result in a non-exempt
prohibited transaction under Section 406 of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA") or Section 4975 of the Internal
Revenue Code (the "Code") and will not subject the Depositor, the Trustee, the
Securities Administrator, the Master Servicer, any Servicer or the Trust Fund to
any obligation or liability in addition to those undertaken in the Agreement or
(ii) a representation letter, in the form as described by the Agreement, stating
that the transferee is not an employee benefit or other plan subject to the
prohibited transaction provisions of ERISA or Section 4975 of the Code (a
"Plan"), or any other person (including an investment manager, a named fiduciary
or a trustee of any Plan) acting, directly or indirectly, on behalf of or
purchasing any Certificate with "plan assets" of any Plan.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
The Certificates, in the aggregate, evidence the entire beneficial ownership
interest in the Trust Fund formed pursuant to the Agreement.

                  The Certificateholder, by its acceptance of this Certificate,
agrees that it will look solely to the Trust Fund for payment hereunder and that
neither the Securities Administrator nor the Trustee is liable to the
Certificateholders for any amount payable under this Certificate or the
Agreement or, except as expressly provided in the Agreement, subject to any
liability under the Agreement.

                  This Certificate does not purport to summarize the Agreement
and reference is made to the Agreement for the interests, rights and limitations
of rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Securities Administrator.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of Certificates affected thereby evidencing not less than 66-2/3% of the
Voting Rights. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder



                                     A-6-5
<PAGE>


and upon all future Holders of this Certificate and of any Certificate issued
upon the transfer hereof or in lieu hereof whether or not notation of such
consent is made upon this Certificate. The Agreement also permits the amendment
thereof, in certain limited circumstances, without the consent of the Holders of
any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Securities Administrator upon surrender of this Certificate for
registration of transfer at the offices or agencies maintained by the Securities
Administrator for such purposes, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Securities Administrator duly
executed by the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Certificates in authorized denominations
representing a like aggregate Percentage Interest will be issued to the
designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Securities Administrator may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith. The Depositor, the Master Servicer, the
Securities Administrator, the Trustee and any agent of any of them may treat the
Person in whose name this Certificate is registered as the owner hereof for all
purposes, and none of Depositor, the Master Servicer, the Securities
Administrator, the Trustee or any such agent shall be affected by notice to the
contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the remittance of all funds due under the Agreement, coinciding
with or following the earlier to occur of (i) the maturity or other liquidation
(or Advance with respect thereto) of the last Mortgage Loan remaining in the
Trust Fund and disposition of all property acquired upon foreclosure or deed in
lieu of foreclosure of any Mortgage Loan or (ii) the optional repurchase by the
party named in the Agreement of all the Mortgage Loans and other assets of the
Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only on or after the Distribution Date on which the
aggregate Scheduled Principal Balance of the Mortgage Loans is less than the
percentage of the aggregate Scheduled Principal Balance specified in the
Agreement of the Mortgage Loans at the Cut-Off Date. The exercise of such right
will effect the early retirement of the Certificates. In no event, however, will
the Trust Fund created by the Agreement continue beyond the expiration of 21
years after the death of certain persons identified in the Agreement.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Securities Administrator by manual signature, this
Certificate shall not be entitled to any benefit under the Agreement, or be
valid for any purpose.

                           2. The Purchaser is acquiring the Certificates for
                  its own account for investment only and not with a view to or
                  for sale in connection with any distribution

                  thereof in any manner that would violate the Act or any
                  applicable state securities laws.

                           3. The Purchaser is (a) a substantial, sophisticated
                  institutional investor having such knowledge and experience in
                  financial and business matters, and, in particular, in such
                  matters related to securities similar to the Certificates,
                  such that it is capable of evaluating the merits and risks of
                  investment in the Certificates, (b) able to bear the economic
                  risks of such an investment and (c) an "accredited investor"
                  within the meaning of Rule 501 (a) promulgated pursuant to the
                  Act.

                           4. The Purchaser has been furnished with, and has had
                  an opportunity to review (a) [a copy of the Private Placement
                  Memorandum, dated ______, 2003, relating to the Certificates
                  (b)] a copy of the Pooling and Servicing Agreement and [(b)]
                  [(c)] such other information concerning the Certificates, the
                  Mortgage Loans and the Depositor as has been requested by the
                  Purchaser from the Depositor or the Seller and is relevant to
                  the Purchaser's decision to purchase the Certificates. The
                  Purchaser has had any questions arising from such review
                  answered by the Depositor or the Seller to the satisfaction of
                  the Purchaser. [If the Purchaser did not purchase the
                  Certificates from the Seller in connection with the initial
                  distribution of the Certificates and was provided with a copy
                  of the Private Placement Memorandum (the "Memorandum")
                  relating to the original sale (the "Original Sale") of the
                  Certificates by the Depositor, the Purchaser acknowledges that
                  such Memorandum was provided to it by the Seller, that the
                  Memorandum was prepared by the Depositor solely for use in
                  connection with the Original Sale and the Depositor did not
                  participate in or facilitate in any way the purchase of the
                  Certificates by the Purchaser from the Seller, and the
                  Purchaser agrees that it will look solely to the Seller and
                  not to the Depositor with respect to any damage, liability,
                  claim or expense arising out of, resulting from or in
                  connection with (a) error or omission, or alleged error or
                  omission, contained in the Memorandum, or (b) any information,
                  development or event arising after the date of the
                  Memorandum.]

                           5. The Purchaser has not and will not nor has it
                  authorized or will it authorize any person to (a) offer,
                  pledge, sell, dispose of or otherwise transfer any
                  Certificate, any interest in any Certificate or any other
                  similar security to any person in any manner, (b) solicit any
                  offer to buy or to accept a pledge, disposition of other
                  transfer of any Certificate, any interest in any Certificate
                  or any other similar security from any person in any manner,
                  (c) otherwise approach or negotiate with respect to any
                  Certificate, any interest in any Certificate or any other
                  similar security with any person in any manner, (d) make any
                  general solicitation by means of general advertising or in any
                  other manner or (e) take any other action, that (as to any of
                  (a) through (e) above) would constitute a distribution of any
                  Certificate under the Act, that would render the disposition
                  of any Certificate a violation of Section 5 of the Act or any
                  state securities law, or that would require registration or
                  qualification pursuant thereto. The Purchaser will not sell or
                  otherwise transfer any of the Certificates, except in
                  compliance with the provisions of the Pooling and Servicing
                  Agreement.

                           Certificates has been made available to us;

                  (iii)    we are able to bear the economic risk of investment

                           not registered under the Act (as to which we
                           acknowledge you have no obligation), the Privately
                           Offered Certificate is sold in a transaction that
