                  This Pooling and Servicing Agreement, is dated and effective
as of January 1, 2005 among MORTGAGE ASSET SECURITIZATION TRANSACTIONS, INC. as
Depositor, OCWEN FEDERAL BANK FSB as Servicer and U.S. BANK NATIONAL ASSOCIATION
as Trustee.

                             PRELIMINARY STATEMENT:

                  The Depositor intends to sell pass-through certificates to be
issued hereunder in multiple classes, which in the aggregate will evidence the
entire beneficial ownership interest in each REMIC (as defined herein) created
hereunder. The Trust Fund will consist of a segregated pool of assets comprised
of the Mortgage Loans and certain other related assets subject to this
Agreement.

                                     REMIC I
                                     -------

                  As provided herein, the Trustee will elect to treat the
segregated pool of assets consisting of the Mortgage Loans and certain other
related assets (other than the Net WAC Rate Carryover Reserve Account, the
Servicer Prepayment Charge Payment Amount and the Cap Contracts) subject to this
Agreement as a REMIC for federal income tax purposes, and such segregated pool
of assets will be designated as "REMIC I." The Class R-I Interest will be the
sole class of "residual interests" in REMIC I for purposes of the REMIC
Provisions (as defined herein). The following table irrevocably sets forth the
designation, the REMIC I Remittance Rate, the initial Uncertificated Balance
and, for purposes of satisfying Treasury Regulation Section 1.860G-1(a)(4)(iii),
the "latest possible maturity date" for each of the REMIC I Regular Interests
(as defined herein). None of the REMIC I Regular Interests will be certificated.

does hereby deliver to, and deposit with, the Trustee (or the Custodian on
behalf of the Trustee) the following documents or instruments with respect to
each Mortgage Loan so transferred and assigned (a "Mortgage File"):

                  (i) the original Mortgage Note, endorsed in blank or in the
         following form: "Pay to the order of U.S. Bank National Association, as
         Trustee under the applicable agreement, without recourse," with all
         prior and intervening endorsements showing a complete chain of
         endorsement from the Originator to the Person so endorsing to the
         Trustee;

                  (ii) the original Mortgage, noting the presence of the MIN of
         the Mortgage Loan and language indicating that the Mortgage Loan is a
         MOM Loan if the Mortgage Loan is a MOM Loan, with evidence of recording
         thereon, and the original recorded power of attorney, if the Mortgage
         was executed pursuant to a power of attorney, with evidence of
         recording thereon;

                  (iii) unless the Mortgage Loan is registered on the MERS(R)
         System, an original Assignment in blank;

                  (iv) the original recorded Assignment or Assignments showing a
         complete chain of assignment from the Originator to the Person
         assigning the Mortgage to the Trustee (or to MERS, if the Mortgage Loan
         is registered on the MERS(R) System and noting the presence of the MIN)
         as contemplated by the immediately preceding clause (iii);

                  (v) the original or copies of each assumption, modification,
         written assurance or substitution agreement, if any; and

                  (vi) the original lender's title insurance policy, together
         with all endorsements or riders that were issued with or subsequent to
         the issuance of such policy, insuring the priority of the Mortgage as a
         first or second lien on the Mortgaged Property represented therein as a
         fee interest vested in the Mortgagor, or in the event such original
         title policy is unavailable, a written commitment or uniform binder or
         preliminary report of title issued by the title insurance or escrow
         company.

                  With respect to a maximum of approximately 1.0% of the
Mortgage Loans, by outstanding Stated Principal Balance of the Mortgage Loans as
of the Cut-off Date, if any original Mortgage Note referred to in Section
2.01(i) above cannot be located, the obligations of the Depositor to deliver
such documents shall be deemed to be satisfied upon delivery to the Trustee (or
the Custodian on behalf of the Trustee) of a photocopy of such Mortgage Note, if

attached hereto. If any of the original Mortgage Notes for which a lost note
affidavit was delivered to the Trustee (or the Custodian on behalf of the
Trustee) is subsequently located, such original Mortgage Note shall be delivered
to the Trustee (or the Custodian on behalf of the Trustee) within three Business
Days.

                  Except with respect to any Mortgage Loan for which MERS is
identified on the Mortgage or on a properly recorded assignment of the Mortgage
as the mortgagee of record, the Trustee shall promptly (within sixty Business
Days following the later of the Closing Date and the date of receipt by the
Trustee or the Custodian of the recording information for a Mortgage, but in no
event later than ninety days following the Closing Date) enforce the obligations
of NC Capital pursuant to the terms of the Mortgage Loan Purchase Agreement to
submit or cause to be submitted for recording, at no expense to the Trust Fund,
the Trustee, the Custodian, the Servicer or the Depositor, in the appropriate
public office for real property records, each Assignment referred to in Sections
2.01(iii) and (iv) above and in connection therewith, the Trustee shall enforce
the obligation of NC Capital pursuant to the terms of the Mortgage Loan Purchase
Agreement to execute each original Assignment in the following form: "U.S. Bank
National Association, as Trustee under the applicable agreement." In the event
that any such Assignment is lost or returned unrecorded because of a defect
therein, the Trustee shall enforce the obligation of NC Capital pursuant to the
Mortgage Loan Purchase Agreement to promptly prepare or cause to be prepared a
substitute Assignment or cure or cause to be cured such defect, as the case may
be, and thereafter cause each such Assignment to be duly recorded.

                  In connection with the assignment of any Mortgage Loan
registered on the MERS(R) System, the Depositor further agrees that it will
cause, within 30 Business Days after the Closing Date, the MERS(R) System to
indicate that such Mortgage Loans have been assigned by the Depositor to the
Trustee in accordance with this Agreement for the benefit of the
Certificateholders by including (or deleting, in the case of Mortgage Loans
which are repurchased in accordance with this Agreement) in such computer files
(a) the code in the field which identifies the specific Trustee and (b) the code
in the field "Pool Field" which identifies the series of the Certificates issued
in connection with such Mortgage Loans. The Depositor further agrees that it
will not, and will not permit the Servicer to, and the Servicer agrees that it
will not, alter the codes referenced in this paragraph with respect to any
Mortgage Loan during the term of this Agreement unless and until such Mortgage
Loan is repurchased in accordance with the terms of this Agreement.

(y) has been lost or such public recording office has retained the original of
such document, the obligations of the Depositor to deliver such documents shall
be deemed to be satisfied upon (1) delivery to the Trustee (or the Custodian on
behalf of the Trustee) of a copy of each such document certified by the
Originator in the case of (x) above or the applicable public recording office in
the case of (y) above to be a true and complete copy of the original that was
submitted for recording and (2) if such copy is certified by the Originator,
delivery to the Trustee (or the Custodian on behalf of the Trustee) promptly
upon receipt thereof of either the original or a copy of such document certified
by the applicable public recording office to be a true and complete copy of the
original. Pursuant to the Mortgage Loan Purchase Agreement, notice shall be
provided to the Trustee and the Rating Agencies by the NC Capital if delivery
pursuant to clause (2) above will be made more than 180 days after the Closing
Date.

                  If the original lender's title insurance policy was not
delivered pursuant to Section 2.01(vi) above, the Depositor shall deliver or
cause to be delivered to the Trustee (or the Custodian on behalf of the
Trustee), promptly after receipt thereof, the original lender's title insurance
policy with a copy thereof to the Servicer. The Depositor shall deliver or cause
to be delivered to the Trustee (or the Custodian on behalf of the Trustee)
promptly upon receipt thereof any other original documents constituting a part
of a Mortgage File received with respect to any Mortgage Loan, including, but
not limited to, any original documents evidencing an assumption or modification
of any Mortgage Loan with a copy thereof to the Servicer.

                  The Depositor shall deliver or cause the Originator, NC
Capital, the Trustee or the Custodian to deliver to the Servicer copies of all
trailing documents required to be included in the servicing file at the same
time the originals or certified copies thereof are delivered to the Trustee or
Custodian, such documents including but not limited to the mortgagee policy of
title insurance and any mortgage loan documents upon return from the recording
office. The Servicer shall not be responsible for any custodian fees or other
costs incurring in obtaining such documents and the Depositor shall cause the
Servicer to be reimbursed for any such costs it may incur in connection with
performing its obligations under this Agreement. Subject to Section 6.03(a), the
Servicer shall have no liability as a result of an inability to service any
Mortgage Loan due to its failure to receive any documents missing from the
Mortgage File or servicing file.

                  All original documents relating to the Mortgage Loans that are
not delivered to the Trustee (or the Custodian on behalf of the Trustee) are and
shall be held by or on behalf of the Originator, NC Capital, the Seller, the
Depositor or the Servicer, as the case may be, in trust for the benefit of the
Trustee on behalf of the Certificateholders. In the event that any such original
document is required pursuant to the terms of this Section 2.01 to be a part of
a Mortgage File, such document shall be delivered promptly to the Trustee (or
the Custodian on behalf of the Trustee). Any such original document delivered to
or held by the Depositor that is not required pursuant to the terms of this
Section to be a part of a Mortgage File, shall be delivered promptly to the
Servicer.

                  The Depositor and the Trustee hereto understand and agree that
it is not intended that any Mortgage Loan be included in the Trust that is a
"High-Cost Home Loan" as defined by the Homeownership and Equity Protection Act
of 1994 or any other applicable predatory or abusive lending laws.

                  The Depositor hereby directs the Trustee to, and the Trustee
hereby agrees to execute, deliver and perform its obligations under each of the
Cap Contracts on the Closing Date and thereafter on behalf of the Holders of the
Group I Certificates, the Group II Certificates and the Mezzanine Certificates.
The Depositor, the Servicer and the Holders of the Group I Certificates, the
Group II Certificates and the Mezzanine Certificates, by their acceptance of
such Certificates, acknowledge and agree that the Trustee shall execute, deliver
and perform its obligations under each of the Cap Contracts and shall do so
solely in its capacity as Trustee of the Trust Fund and not in its individual
capacity.

                  SECTION 2.02. Acceptance of REMIC I by Trustee.

                  The Trustee acknowledges receipt (or receipt by the Custodian
as the duly appointed agent of the Trustee), subject to the provisions of
Section 2.01 and subject to any exceptions noted on the exception report
described in the next paragraph below, of the documents referred to in Section
2.01 (other than such documents described in Section 2.01(v)) above and all
other assets included in the definition of "REMIC I" under clauses (i), (iii),
(iv) and (v) (to the extent of amounts deposited into the Distribution Account)
and declares that it holds and will hold such documents and the other documents
delivered to it constituting a Mortgage File, and that it holds or will hold all
such assets and such other assets included in the definition of "REMIC I" in
trust for the exclusive use and benefit of all present and future
Certificateholders.

                  The Trustee (or the Custodian on behalf of the Trustee) agrees
to execute and deliver to the Depositor and the NIMS Insurer on or prior to the
Closing Date an acknowledgment of receipt of the original Mortgage Note (with
any exceptions noted), substantially in the form attached as Exhibit C-3 hereto.

                  The Trustee (or the Custodian on behalf of the Trustee)
agrees, for the benefit of the Certificateholders and the NIMS Insurer, to
review each Mortgage File and, within 45 days of the Closing Date, to certify in
substantially the form attached hereto as Exhibit C-1 that, as to each Mortgage
Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan paid in
full or any Mortgage Loan specifically identified in the exception report
annexed thereto as not being covered by such certification), (i) all documents
constituting part of such Mortgage File (other than such documents described in
Section 2.01(v)) required to be delivered to it pursuant to this Agreement are
in its possession, (ii) such documents have been reviewed by it or the Custodian
and appear regular on their face and relate to such Mortgage Loan and (iii)
based on its or the Custodian's examination and only as to the foregoing, the
information set forth in the Mortgage Loan Schedule that corresponds to items
(1), (3), (12), (15) and (18) of the definition of "Mortgage Loan Schedule"
accurately reflects information set forth in the Mortgage File. It is herein
acknowledged that, in conducting such review, the Trustee (or the Custodian on
behalf of the Trustee) is under no duty or obligation (i) to inspect, review or
examine any such documents, instruments, certificates or other papers to
determine whether they are genuine,


                                       58
<PAGE>

enforceable, or appropriate for the represented purpose or whether they have
actually been recorded or that they are other than what they purport to be on
their face or (ii) to determine whether any Mortgage File should include any of
the documents specified in clause (v) of Section 2.01.

                  Prior to the first anniversary date of this Agreement, the
Trustee shall deliver (or cause the Custodian to deliver) to the Depositor, the
NIMS Insurer and the Servicer a final certification in the form annexed hereto
as Exhibit C-2 evidencing the completeness of the Mortgage Files, with any
applicable exceptions noted thereon, and the Servicer shall forward a copy
thereof to any Sub-Servicer.

                  If in the process of reviewing the Mortgage Files and making
or preparing, as the case may be, the certifications referred to above, the
Trustee (or the Custodian on behalf of the Trustee) finds any document or
documents constituting a part of a Mortgage File to be missing or defective in
any material respect, at the conclusion of its review the Trustee (or the
Custodian on behalf of the Trustee) shall so notify the Depositor, the NIMS
Insurer and the Servicer. In addition, upon the discovery by the Depositor, the
NIMS Insurer, the Servicer or the Trustee of a breach of any of the
representations and warranties made by NC Capital or the Seller in the Mortgage
Loan Purchase Agreement in respect of any Mortgage Loan which materially
adversely affects such Mortgage Loan or the interests of the related
Certificateholders in such Mortgage Loan, the party discovering such breach
shall give prompt written notice to the other parties.

                  The Trustee (or the Custodian on behalf of the Trustee) shall,
at the written request and expense of any Certificateholder, provide a written
report to such Certificateholder of all Mortgage Files released to the Servicer
for servicing purposes.

                  The Depositor and the Trustee intend that the assignment and
transfer herein contemplated constitute a sale of the Mortgage Loans, the
related Mortgage Notes and the related documents, conveying good title thereto
free and clear of any liens and encumbrances, from the Depositor to the Trustee
in trust for the benefit of the Certificateholders and that such property not be
part of the Depositor's estate or property of the Depositor in the event of any
insolvency by the Depositor. In the event that such conveyance is deemed to be,
or to be made as security for, a loan, the parties intend that the Depositor
shall be deemed to have granted and does hereby grant to the Trustee a first
priority perfected security interest in all of the Depositor's right, title and
interest in and to the Mortgage Loans, the related Mortgage Notes and the
related documents, and that this Agreement shall constitute a security agreement
under applicable law.

                  SECTION 2.03. Repurchase or Substitution of Mortgage Loans by
                                NC Capital or the Seller.

                  (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
the breach by NC Capital or the Seller of any representation, warranty or
covenant under the Mortgage Loan Purchase Agreement (including any
representation, warranty or covenant regarding the Prepayment Charge Schedule)
in respect of any Mortgage Loan that materially adversely affects the value of
such Mortgage Loan or the interest therein of the Certificateholders, the
Trustee shall promptly


                                       59
<PAGE>

notify NC Capital, the NIMS Insurer, the Seller and the Servicer of such defect,
missing document or breach and request that NC Capital or the Seller, as
applicable, deliver such missing document or cure such defect or breach within
90 days from the date NC Capital or the Seller, as applicable, was notified of
such missing document, defect or breach, and if NC Capital or the Seller, as
applicable, 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 NC Capital or the Seller, as applicable, under the Mortgage Loan
Purchase Agreement to repurchase such Mortgage Loan from REMIC I at the Purchase
Price within 90 days after the date on which NC Capital or the Seller, as
applicable, was notified (subject to Section 2.03(c)) of such missing document,
defect or breach, if and to the extent that NC Capital or the Seller, as
applicable, is obligated to do so under the Mortgage Loan Purchase Agreement.
The Purchase Price for the repurchased Mortgage Loan shall be remitted to the
Servicer for deposit in the Collection Account and the Trustee (or the Custodian
on behalf of the Trustee), upon receipt of written certification from the
Servicer of such deposit, shall release to NC Capital or the Seller, as
applicable, the related Mortgage File and the Trustee (or the Custodian on
behalf of the Trustee) shall execute and deliver such instruments of transfer or
assignment, in each case without recourse, as NC Capital or the Seller, as
applicable, shall furnish to it and as shall be necessary to vest in NC Capital
or the Seller, as applicable, any Mortgage Loan released pursuant hereto. In
furtherance of the foregoing, if NC Capital or the Seller, as applicable, is not
a member of MERS and repurchases a Mortgage Loan which is registered on the
MERS(R) System, NC Capital or the Seller, as applicable, at its own expense and
without any right of reimbursement, shall cause MERS to execute and deliver an
assignment of the Mortgage in recordable form to transfer the Mortgage from MERS
to NC Capital or the Seller, as applicable, and shall cause such Mortgage to be
removed from registration on the MERS(R) System in accordance with MERS' rules
and regulations. Neither the Trustee nor the Custodian shall have any further
responsibility with regard to such Mortgage File. In lieu of repurchasing any
such Mortgage Loan as provided above, if so provided in the Mortgage Loan
Purchase Agreement, NC Capital or the Seller, as applicable, may cause such
Mortgage Loan to be removed from REMIC I (in which case it shall become a
Deleted Mortgage Loan) and substitute one or more Qualified Substitute Mortgage
Loans in the manner and subject to the limitations set forth in Section 2.03(b);
provided, however, NC Capital or the Seller, as applicable, may not substitute a
Qualified Substitute Mortgage Loan for any Deleted Mortgage Loan that violates
any predatory or abusive lending law. It is understood and agreed that the
obligation of NC Capital or the Seller, as applicable, to cure or to repurchase
(or to substitute for) any Mortgage 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.

                  (b) Any substitution of Qualified Substitute Mortgage Loans
for Deleted Mortgage Loans made pursuant to Section 2.03(a) must be effected
prior to the date which is two years after the Startup Day for REMIC I.

                  As to any Deleted Mortgage Loan for which NC Capital or the
Seller, as applicable, substitutes a Qualified Substitute Mortgage Loan or
Loans, such substitution shall be effected by NC Capital or the Seller, as
applicable, delivering to the Trustee (or the Custodian on behalf of the
Trustee), for such Qualified Substitute Mortgage Loan or Loans, the Mortgage
Note, the Mortgage, the Assignment in blank or to the Trustee, and such other
documents and


                                       60
<PAGE>

agreements, with all necessary endorsements thereon, as are required by Section
2.01, together with an Officers' Certificate providing that each such Qualified
Substitute Mortgage Loan satisfies the definition thereof and specifying the
Substitution Adjustment Amount (as described below), if any, in connection with
such substitution. The Trustee (or the Custodian on behalf of the Trustee) shall
acknowledge receipt for such Qualified Substitute Mortgage Loan or Loans and,
within ten Business Days thereafter, review such documents as specified in
Section 2.02 and deliver to the Depositor, the NIMS Insurer and the Servicer,
with respect to such Qualified Substitute Mortgage Loan or Loans, a
certification substantially in the form attached hereto as Exhibit C-1, with any
applicable exceptions noted thereon. Within one year of the date of
substitution, the Trustee (or the Custodian on behalf of the Trustee) shall
deliver to the Depositor, the NIMS Insurer and the Servicer a certification
substantially in the form of Exhibit C-2 hereto with respect to such Qualified
Substitute Mortgage Loan or Loans, with any applicable exceptions noted thereon.
Monthly Payments due with respect to Qualified Substitute Mortgage Loans in the
month of substitution are not part of REMIC I and will be retained by NC Capital
or the Seller, as applicable. For the month of substitution, distributions to
Certificateholders will reflect the Monthly Payment due on such Deleted Mortgage
Loan on or before the Due Date in the month of substitution, and NC Capital or
the Seller, as applicable, shall thereafter be entitled to retain all amounts
subsequently received in respect of such Deleted Mortgage Loan. The Depositor
shall give or cause to be given written notice to the Certificateholders and the
NIMS Insurer that such substitution has taken place, shall amend the Mortgage
Loan Schedule to reflect the removal of such Deleted Mortgage Loan from the
terms of this Agreement and the substitution of the Qualified Substitute
Mortgage Loan or Loans and shall deliver a copy of such amended Mortgage Loan
Schedule to the Trustee, the Custodian, the Servicer and the NIMS Insurer. Upon
such substitution, such Qualified Substitute Mortgage Loan or Loans shall
constitute part of the Mortgage Pool 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 in the Mortgage Loan
Purchase Agreement.

                  For any month in which NC Capital or the Seller, as
applicable, substitutes one or more Qualified Substitute Mortgage Loans for one
or more Deleted Mortgage Loans, the Servicer will determine the amount (the
"Substitution Adjustment Amount"), if any, by which the aggregate Purchase Price
of all such Deleted Mortgage Loans exceeds the aggregate of, as to each such
Qualified Substitute Mortgage Loan, the Stated Principal Balance thereof as of
the date of substitution, together with one month's interest on such Stated
Principal Balance at the applicable Net Mortgage Rate, plus all outstanding
Advances and Servicing Advances (including Nonrecoverable Advances and
Nonrecoverable Servicing Advances) related thereto. On the date of such
substitution, NC Capital or the Seller, as applicable, will deliver or cause to
be delivered to the Servicer for deposit in the Collection Account an amount
equal to the Substitution Adjustment Amount, if any, and the Trustee (or the
Custodian on behalf of the Trustee), upon receipt of the related Qualified
Substitute Mortgage Loan or Loans and written notice by the Servicer of such
deposit, shall release to NC Capital or the Seller, as applicable, the related
Mortgage File or Files and the Trustee (or the Custodian on behalf of the
Trustee) shall execute and deliver such instruments of transfer or assignment,
in each case without recourse, NC Capital or the Seller, as applicable, shall
deliver to it and as shall be necessary to vest therein any Deleted Mortgage
Loan released pursuant hereto.



                                       61
<PAGE>

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

                  (c) Upon discovery by the Depositor, the NIMS Insurer, the
Originator, NC Capital, the Seller, the Servicer or the Trustee that any
Mortgage Loan does not constitute a "qualified mortgage" within the meaning of
Section 860G(a)(3) of the Code, the party discovering such fact shall within two
Business Days give written notice thereof to the other parties hereto and the
Trustee shall give written notice to NC Capital and the Seller. In connection
therewith, NC Capital, the Seller or the Depositor shall repurchase or, subject
to the limitations set forth in Section 2.03(b), substitute one or more
Qualified Substitute Mortgage Loans for the affected Mortgage Loan within 90
days of the earlier of discovery or receipt of such notice with respect to such
affected Mortgage Loan. Such repurchase or substitution shall be made by (i) NC
Capital or the Seller, as the case may be, if the affected Mortgage Loan's
status as a non-qualified mortgage is or results from a breach of any
representation, warranty or covenant made by NC Capital or the Seller, as the
case may be, under the Mortgage Loan Purchase Agreement, or (ii) the Depositor,
if the affected Mortgage Loan's status as a non-qualified mortgage is a breach
of no representation or warranty. Any such repurchase or substitution shall be
made in the same manner as set forth in Section 2.03(a). The Trustee (or the
Custodian on behalf of the Trustee) shall reconvey to the Depositor, NC Capital
or the Seller, as the case may be, the Mortgage Loan to be released pursuant
hereto in the same manner, and on the same terms and conditions, as it would a
Mortgage Loan repurchased for breach of a representation or warranty.

                  SECTION 2.04. Reserved

                  SECTION 2.05. Representations, Warranties and Covenants of the
                                Servicer.

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

                  (i) The Servicer is a federally chartered savings bank duly
         organized and validly existing under the laws of the United States and
         is duly authorized and qualified to transact any and all business
         contemplated by this Agreement to be conducted by the Servicer in any
         state in which a Mortgaged Property is located or is otherwise not
         required under applicable law to effect such qualification and, in any
         event, is in compliance with the doing business laws of any such State,
         to the extent necessary to ensure its ability to enforce each Mortgage
         Loan and to service the Mortgage Loans in accordance with the terms of
         this Agreement;

                  (ii) The Servicer has the full power and authority to conduct
         its business as presently conducted by it and to execute, deliver and
         perform, and to enter into and


                                       62
<PAGE>

         consummate, all transactions contemplated by this Agreement. The
         Servicer has duly authorized the execution, delivery and performance of
         this Agreement, has duly executed and delivered this Agreement, and
         this Agreement, assuming due authorization, execution and delivery by
         the Depositor and the Trustee, constitutes a legal, valid and binding
         obligation of the Servicer, enforceable against it in accordance with
         its terms except as the enforceability thereof may be limited by
         bankruptcy, insolvency, 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
         Servicer, the servicing of the Mortgage Loans by the Servicer
         hereunder, the consummation by the Servicer of any other of the
         transactions herein contemplated, and the fulfillment of or compliance
         with the terms hereof are in the ordinary course of business of the
         Servicer and will not (A) result in a breach of any term or provision
         of the charter or by-laws of the Servicer or (B) conflict with, result
         in a breach, violation or acceleration of, or result in a default
         under, the terms of any other material agreement or instrument to which
         the Servicer is a party or by which it may be bound, or any statute,
         order or regulation applicable to the Servicer of any court, regulatory
         body, administrative agency or governmental body having jurisdiction
         over the Servicer; and the Servicer is not a party to, bound by, or in
         breach or violation of any indenture or other agreement or instrument,
         or subject to or in violation of any statute, order or regulation of
         any court, regulatory body, administrative agency or governmental body
         having jurisdiction over it, which materially and adversely affects or,
         to the Servicer's knowledge, would in the future materially and
         adversely affect, (x) the ability of the Servicer to perform its
         obligations under this Agreement or (y) the business, operations,
         financial condition, properties or assets of the Servicer taken as a
         whole;

                  (iv) The Servicer is a HUD approved servicer. No event has
         occurred, including but not limited to a change in insurance coverage,
         that would make the Servicer unable to comply with HUD eligibility
         requirements or that would require notification to HUD;

                  (v) The Servicer does not believe, nor does it have any reason
         or cause to believe, that it cannot perform each and every covenant
         made by it and contained in this Agreement;

                  (vi) No information, certificate of an officer, statement
         furnished in writing or report delivered to the Trustee by the Servicer
         in connection with the transactions contemplated hereby contains any
         untrue statement of a material fact or omits to state a material fact
         necessary in order to make the statements contained therein, in light
         of the circumstances under which they were made, not misleading (except
         to the extent that any such information, statement or report has been
         corrected or superseded in writing by the Servicer as of the Closing
         Date, it being understood (i) that the Servicer has delivered no
         certificate of an officer prior to the Closing Date and (ii) that any
         representations, warranties and indemnifications as to the accuracy and
         completeness of the Prospectus Supplement made by the Servicer in
         agreements and Officers' Certificates delivered by the Servicer on the
         Closing Date in connection with the transactions contemplated by this

                                       63
<PAGE>

         Agreement shall be interpreted such that the information in the
         Prospectus Supplement is deemed to correct and/or supersede as of the
         Closing Date, within the meaning of this parenthetical, any
         information, statement or report delivered by the Servicer to the
         Trustee prior to the Closing Date that is inconsistent with the
         information in the Prospectus Supplement or that was omitted from such
         information, statement or report delivered prior to the Closing Date);

                  (vii) No litigation is pending against the Servicer that would
         materially and adversely affect the execution, delivery or
         enforceability of this Agreement or the ability of the Servicer to
         service the Mortgage Loans or to perform any of its other obligations
         hereunder in accordance with the terms hereof;

                  (viii) There are no actions or proceedings against, or
         investigations known to it of, the Servicer before any court,
         administrative or other tribunal (A) that might prohibit its entering
         into this Agreement, (B) seeking to prevent the consummation of the
         transactions contemplated by this Agreement or (C) that might prohibit
         or materially and adversely affect the performance by the Servicer of
         its obligations under, or validity or enforceability of, this
         Agreement;

                  (ix) No consent, approval, authorization or order of any court
         or governmental agency or body is required for the execution, delivery
         and performance by the Servicer of, or compliance by the Servicer with,
         this Agreement or the consummation by it of the transactions
         contemplated by this Agreement, except for such consents, approvals,
         authorizations or orders, if any, that have been obtained prior to the
         Closing Date;

                  (x) The Servicer will not waive any Prepayment Charge unless
         it is waived in accordance with the standard set forth in Section 3.01;
         and

                  (xi) With respect to each Mortgage Loan, the Servicer has
         fully and accurately furnished with respect to the period in which it
         serviced the Mortgage Loans, and will continue to fully and accurately
         furnish, complete information on the related borrower credit files to
         Equifax, Experian and Trans Union Credit Information Company, in
         accordance with the Fair Credit Reporting Act and its implementing
         regulations.

                  It is understood and agreed that the representations,
warranties and covenants set forth in this Section 2.05 shall survive delivery
of the Mortgage Files to the Trustee or the Custodian and shall inure to the
benefit of the Trustee, the Depositor and the Certificateholders. Upon discovery
by any of the Depositor, the Servicer, the NIMS Insurer or the Trustee of a
breach of any of the foregoing representations, warranties and covenants which
materially and adversely affects the value of any Mortgage Loan or the interests
therein of the Certificateholders, the party discovering such breach shall give
prompt written notice (but in no event later than two Business Days following
such discovery) to the Servicer, the NIMS Insurer and the Trustee.
Notwithstanding the foregoing, within 90 days of the earlier of discovery by the
Servicer or receipt of notice by the Servicer of the breach of the
representation or covenant of the Servicer set forth in Section 2.05(x) above
which materially and adversely affects the interests of the Holders of the Class
P Certificates in any Prepayment Charge, the Servicer must pay the amount of
such waived Prepayment Charge, for the benefit of the Holders of the Class P

                                       64
<PAGE>

Certificates, by depositing such amount into the Collection Account. The
foregoing shall not, however, limit any remedies available to the
Certificateholders, the Depositor or the Trustee on behalf of the
Certificateholders, pursuant to the Mortgage Loan Purchase Agreement respecting
a breach of the representations, warranties and covenants of the Originator made
in its capacity as a party to the Mortgage Loan Purchase Agreement.

                  SECTION 2.06. Conveyance of REMIC Regular Interests and
                                Acceptance of REMIC I, REMIC II, REMIC III and
                                REMIC IV by the Trustee; Issuance of
                                Certificates.

         (a) The Depositor, concurrently with the execution and delivery hereof,
does hereby transfer, assign, set over and otherwise convey in trust to the
Trustee without recourse all the right, title and interest of the Depositor in
and to the assets described in the definition of REMIC I for the benefit of the
holders of the REMIC I Regular Interests (which are uncertificated) and the
Class R Certificates (in respect of the Class R-I Interest). The Trustee
acknowledges receipt of the assets described in the definition of REMIC I and
declares that it holds and will hold the same in trust for the exclusive use and
benefit of the holders of the REMIC I Regular Interests and the Class R
Certificates (in respect of the Class R-I Interest). The interests evidenced by
the Class R-I Interest, together with the REMIC I Regular Interests, constitute
the entire beneficial ownership interest in REMIC I.

         (b) The Depositor, concurrently with the execution and delivery hereof,
does hereby transfer, assign, set over and otherwise convey in trust to the
Trustee without recourse all the right, title and interest of the Depositor in
and to the REMIC I Regular Interests (which are uncertificated) for the benefit
of the Holders of the REMIC II Regular Interests and the Class R Certificates
(in respect of the Class R-II Interest). The Trustee acknowledges receipt of the
REMIC I Regular Interests and declares that it holds and will hold the same in
trust for the exclusive use and benefit of the Holders of the REMIC II Regular
Interests and the Class R Certificates (in respect of the Class R-II Interest).
The interests evidenced by the Class R-II Interest, together with the Regular

the exclusive use and benefit of the Holders of the Class P Certificates and the
Class R-X Certificates (in respect of the Class R-IV Interest). The interests

                                Certificates.

                  (a) The Trustee acknowledges the assignment to it of the REMIC
I Regular Interests and, concurrently therewith and in exchange therefor,

                                  ARTICLE III

                          ADMINISTRATION AND SERVICING
                              OF THE MORTGAGE LOANS

                  SECTION 3.01. Servicer to Act as Servicer.

                  The Servicer shall service and administer the Mortgage Loans
on behalf of the Trust Fund and in the best interests of and for the benefit of
the Certificateholders (as determined by the Servicer in its reasonable
judgment) in accordance with the terms of this Agreement and the respective
Mortgage Loans and, to the extent consistent with such terms, in the same manner
in which it services and administers similar mortgage loans for its own
portfolio, giving due consideration to customary and usual standards of practice
of mortgage lenders and loan servicers administering similar mortgage loans but
without regard to:

                  (i) any relationship that the Servicer, any Sub-Servicer or
         any Affiliate of the Servicer or any Sub-Servicer may have with the
         related Mortgagor;

                  (ii) the ownership or non-ownership of any Certificate by the
         Servicer or any Affiliate of the Servicer;

                  (iii) the Servicer's obligation to make Advances or Servicing
         Advances; or

                  (iv) the Servicer's or any Sub-Servicer's right to receive
         compensation for its services hereunder or with respect to any
         particular transaction.

                  To the extent consistent with the foregoing, the Servicer (a)
shall seek to maximize the timely and complete recovery of principal and
interest on the Mortgage Notes and (b) shall waive (or permit a Sub-Servicer to
waive) a Prepayment Charge only under the following circumstances: (i) such
waiver is standard and customary in servicing similar mortgage loans and such
waiver relates to a default or a reasonably foreseeable default and would, in
the reasonable judgment of the Servicer, maximize recovery of total proceeds
taking into account the value of such Prepayment Charge and the related Mortgage
Loan, (ii) the collection of such Prepayment Charge would be in violation of
applicable laws, (iii) the amount of the Prepayment Charge set forth on the
Prepayment Charge Schedule is not consistent with the related Mortgage Note or
is otherwise unenforceable or (iv) the collection of such Prepayment Charge
would be considered "predatory" pursuant to written guidance published or issued
by any applicable federal, state or local regulatory authority acting in its
official capacity and having jurisdiction over such matters. If a Prepayment
Charge is waived as permitted by meeting the standard described in clauses (ii),
(iii) or (iv) above, then the Trustee shall, enforce the obligation of NC
Capital to pay the amount of such waived Prepayment Charge to the Trustee for
deposit in the Distribution Account for the benefit of the Holders of the Class
P Certificates. Subject only to the above-described servicing standards and the
terms of this Agreement and of the Mortgage Loans, the Servicer shall have full
power and authority, acting alone or through Sub-Servicers as provided in
Section 3.02, to do or cause to be done any and all things in connection with
such servicing and administration which it may deem necessary or desirable.
Without limiting the generality of the foregoing, the Servicer in its own name
or in the name of a Sub-Servicer is


                                       67
<PAGE>

hereby authorized and empowered by the Trustee when the Servicer believes it
appropriate in its best judgment in accordance with the servicing standards set
forth above, to execute and deliver, on behalf of the Certificateholders and the
Trustee, and upon notice to the Trustee, any and all instruments of satisfaction
or cancellation, or of partial or full release or discharge, and all other
comparable instruments, with respect to the Mortgage Loans and the Mortgaged
Properties and to institute foreclosure proceedings or obtain a deed-in-lieu of
foreclosure so as to convert the ownership of such properties, and to hold or
cause to be held title to such properties, on behalf of the Trustee and
Certificateholders. The Servicer shall service and administer the Mortgage Loans
in accordance with applicable state and federal law and shall provide to the
Mortgagors any reports required to be provided to them thereby. The Servicer
shall also comply in the performance of this Agreement with all reasonable rules
and requirements of each insurer under any standard hazard insurance policy.
Subject to Section 3.17, within 15 days of the Closing Date, the Trustee shall
execute, at the written request of the Servicer, and furnish to the Servicer and
any Sub-Servicer any special or limited powers of attorney and other documents
necessary or appropriate to enable the Servicer or any Sub-Servicer to carry out
their servicing and administrative duties hereunder and the Trustee shall not be
liable for the actions of the Servicer or any Sub-Servicers under such powers of
attorney.

                  The Servicer further is authorized and empowered by the
Trustee, on behalf of the Certificateholders and the Trustee, in its own name or
in the name of the Sub-Servicer, when the Servicer or the Sub-Servicer, as the
case may be, believes it is appropriate in its best judgment to register any
Mortgage Loan on the MERS(R) System, or cause the removal from the registration
of any Mortgage Loan on the MERS(R) System, to execute and deliver, on behalf of
the Trustee and the Certificateholders or any of them, any and all instruments
of assignment and other comparable instruments with respect to such assignment
or re-recording of a Mortgage in the name of MERS, solely as nominee for the
Trustee and its successors and assigns. Any reasonable expenses incurred in
connection with the actions described in the preceding sentence or as a result
of MERS discontinuing or becoming unable to continue operations in connection
with the MERS(R) System, shall be reimbursable to the Servicer by withdrawal
from the Collection Account pursuant to Section 3.11.

                  Subject to Section 3.09, in accordance with the standards of
the preceding paragraph, the Servicer shall advance or cause to be advanced
funds as necessary for the purpose of effecting the timely payment of taxes and
assessments on the Mortgaged Properties, which advances shall be Servicing
Advances reimbursable in the first instance from related collections from the
Mortgagors pursuant to Section 3.09, and further as provided in Section 3.11.
Any cost incurred by the Servicer or by Sub-Servicers in effecting the timely
payment of taxes and assessments on a Mortgaged Property shall not, for the
purpose of calculating distributions to Certificateholders, be added to the
unpaid Stated Principal Balance of the related Mortgage Loan, notwithstanding
that the terms of such Mortgage Loan so permit.

                  Notwithstanding anything in this Agreement to the contrary,
the Servicer may not make any future advances with respect to a Mortgage Loan
(except as provided in Section 4.03) and the Servicer shall not (i) permit any
modification with respect to any Mortgage Loan that would change the Mortgage
Rate, reduce or increase the Stated Principal Balance (except for reductions
resulting from actual payments of principal) or change the final maturity date
on such Mortgage Loan (unless, as provided in Section 3.07, the Mortgagor is in
default with respect to


                                       68
<PAGE>

the Mortgage Loan or such default is, in the judgment of the Servicer,
reasonably foreseeable) or (ii) permit any modification, waiver or amendment of
any term of any Mortgage Loan that would both (A) effect an exchange or
reissuance of such Mortgage Loan under Section 1001 of the Code (or Treasury
regulations promulgated thereunder) and (B) cause any Trust REMIC to fail to
qualify as a REMIC under the Code or the imposition of any tax on "prohibited
transactions" or "contributions after the startup date" under the REMIC
Provisions.

                  Notwithstanding anything in this Agreement to the contrary and
notwithstanding its ability to do so pursuant to the terms of the related
Mortgage Note, the Servicer shall not be required to enforce any provision in
any Mortgage Note the enforcement of which would violate federal, state or local
laws or ordinances designed to discourage predatory lending practices.

                  The Servicer may delegate its responsibilities under this
Agreement; provided, however, that no such delegation shall release the Servicer
from the responsibilities or liabilities arising under this Agreement.

                  SECTION 3.02. Sub-Servicing Agreements Between Servicer and
                                Sub-Servicers.

                  (a) The Servicer may enter into Sub-Servicing Agreements with
Sub-Servicers for the servicing and administration of the Mortgage Loans;
provided, however, that (i) such sub-servicing arrangement and the terms of the
related Sub-Servicing Agreement must provide for the servicing of the Mortgage
Loans in a manner consistent with the servicing arrangement contemplated
hereunder and (ii) the NIMS Insurer shall have consented to such Sub-Servicing
Agreement. The Trustee is hereby authorized to acknowledge, at the request of
the Servicer, any Sub-Servicing Agreement that meets the requirements applicable
to Sub-Servicing Agreements set forth in this Agreement and that is otherwise
permitted under this Agreement.

                  Each Sub-Servicer shall be (i) authorized to transact business
in the state or states where the related Mortgaged Properties it is to service
are situated, if and to the extent required by applicable law to enable the
Sub-Servicer to perform its obligations hereunder and under the Sub-Servicing
Agreement and (ii) a Freddie Mac or Fannie Mae approved mortgage servicer. Each
Sub-Servicing Agreement must impose on the Sub-Servicer requirements conforming
to the provisions set forth in Section 3.08 and provide for servicing of the
Mortgage Loans consistent with the terms of this Agreement. The Servicer will
examine each Sub-Servicing Agreement and will be familiar with the terms
thereof. The terms of any Sub-Servicing Agreement will not be inconsistent with
any of the provisions of this Agreement. The Servicer and the Sub-Servicers may
enter into and make amendments to the Sub-Servicing Agreements or enter into
different forms of Sub-Servicing Agreements; provided, however, that any such
amendments or different forms shall be consistent with and not violate the
provisions of this Agreement, and that no such amendment or different form shall
be made or entered into which could be reasonably expected to be materially
adverse to the interests of the Certificateholders without the consent of the
Holders of Certificates entitled to at least 66% of the Voting Rights; provided,
further, that the consent of the Holders of Certificates entitled to at least
66% of the Voting Rights shall not be required (i) to cure any ambiguity or
defect in a Sub-Servicing Agreement, (ii) to correct, modify or supplement any
provisions of a Sub-Servicing Agreement, or (iii) to make any other provisions
with respect to matters or questions arising under a Sub-


                                       69
<PAGE>

Servicing Agreement, which, in each case, shall not be inconsistent with the
provisions of this Agreement. Any variation without the consent of the Holders
of Certificates entitled to at least 66% of the Voting Rights from the
provisions set forth in Section 3.08 relating to insurance or priority
requirements of Sub-Servicing Accounts, or credits and charges to the
Sub-Servicing Accounts or the timing and amount of remittances by the
Sub-Servicers to the Servicer, are conclusively deemed to be inconsistent with
this Agreement and therefore prohibited. The Servicer shall deliver to the
Trustee and the NIMS Insurer copies of all Sub-Servicing Agreements, and any
amendments or modifications thereof, promptly upon the Servicer's execution and
delivery of such instruments.

                  (b) As part of its servicing activities hereunder, the
Servicer, for the benefit of the Trustee and the Certificateholders, shall
enforce the obligations of each Sub-Servicer under the related Sub-Servicing
Agreement, including, without limitation, any obligation of a Sub-Servicer to
make advances in respect of delinquent payments as required by a Sub-Servicing
Agreement. Such enforcement, including, without limitation, the legal
prosecution of claims, termination of Sub-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 Servicer, in its good faith business judgment,
would require were it the owner of the related Mortgage Loans. The Servicer
shall pay the costs of such enforcement at its own expense, and shall be
reimbursed therefor only (i) from a general recovery resulting from such
enforcement, to the extent, if any, that such recovery exceeds all amounts due
in respect of the related Mortgage Loans, or (ii) from a specific recovery of
costs, expenses or attorneys'fees against the party against whom such
enforcement is directed.

                  SECTION 3.03. Successor Sub-Servicers.

                  The Servicer, with the consent of the NIMS Insurer, shall be
entitled to terminate any Sub-Servicing Agreement and the rights and obligations
of any Sub-Servicer pursuant to any Sub-Servicing Agreement in accordance with
the terms and conditions of such Sub-Servicing Agreement. In the event of
termination of any Sub-Servicer, all servicing obligations of such Sub-Servicer
shall be assumed simultaneously by the Servicer without any act or deed on the
part of such Sub-Servicer or the Servicer, and the Servicer either shall service
directly the related Mortgage Loans or shall enter into a Sub-Servicing
Agreement with a successor Sub-Servicer which qualifies under Section 3.02.

                  Any Sub-Servicing Agreement shall include the provision that
such agreement may be immediately terminated by the Trustee (if the Trustee is
acting as Servicer) without fee, in accordance with the terms of this Agreement,
in the event that the Servicer (or the Trustee, if it is then acting as
Servicer) shall, for any reason, no longer be the Servicer (including
termination due to a Servicer Event of Default).

                  SECTION 3.04. Liability of the Servicer.

                  Notwithstanding any Sub-Servicing Agreement or the provisions
of this Agreement relating to agreements or arrangements between the Servicer
and a Sub-Servicer or reference to actions taken through a Sub-Servicer or
otherwise, the Servicer shall remain obligated and primarily liable to the
Trustee and the Certificateholders for the servicing and


                                       70
<PAGE>

administering of the Mortgage Loans in accordance with the provisions of Section
3.01 without diminution of such obligation or liability by virtue of such
Sub-Servicing Agreements or arrangements or by virtue of indemnification from
the Sub-Servicer and to the same extent and under the same terms and conditions
as if the Servicer alone were servicing and administering the Mortgage Loans.
The Servicer shall be entitled to enter into any agreement with a Sub-Servicer
for indemnification of the Servicer by such Sub-Servicer and nothing contained
in this Agreement shall be deemed to limit or modify such indemnification.

                  SECTION 3.05. No Contractual Relationship Between
                                Sub-Servicers and the Trustee, the NIMS Insurer
                                or Certificateholders.

                  Any Sub-Servicing Agreement that may be entered into and any
transactions or services relating to the Mortgage Loans involving a Sub-Servicer
in its capacity as such shall be deemed to be between the Sub-Servicer and the
Servicer alone, and the Trustee, the NIMS Insurer and the Certificateholders
shall not be deemed parties thereto and shall have no claims, rights,
obligations, duties or liabilities with respect to the Sub-Servicer except as
set forth in Section 3.06. The Servicer shall be solely liable for all fees owed
by it to any Sub-Servicer, irrespective of whether the Servicer's compensation
pursuant to this Agreement is sufficient to pay such fees.

                  SECTION 3.06. Assumption or Termination of Sub-Servicing
                                Agreements by Trustee.

                  In the event the Servicer shall for any reason no longer be
the Servicer (including by reason of the occurrence of a Servicer Event of
Default), the Trustee or its designee shall thereupon assume all of the rights
and obligations of the Servicer under each Sub-Servicing Agreement that the
Servicer may have entered into, unless the Trustee elects to terminate any
Sub-Servicing Agreement in accordance with its terms as provided in Section
3.03. Upon such assumption, the Trustee, its designee or the successor servicer
for the Trustee appointed pursuant to Section 7.02 shall be deemed, subject to
Section 3.03, to have assumed all of the Servicer's interest therein and to have
replaced the Servicer as a party to each Sub-Servicing Agreement to the same
extent as if each Sub-Servicing Agreement had been assigned to the assuming
party, except that (i) the Servicer shall not thereby be relieved of any
liability or obligations under any Sub-Servicing Agreement that arose before it
ceased to be the Servicer and (ii) neither of the Trustee nor, its designee or
any successor Servicer shall be deemed to have assumed any liability or
obligation of the Servicer that arose before it ceased to be the Servicer.

                  The Servicer at its expense shall, upon request of the
Trustee, deliver to the assuming party all documents and records relating to
each Sub-Servicing Agreement and the Mortgage Loans then being serviced and an
accounting of amounts collected and held by or on behalf of it, and otherwise
use its best efforts to effect the orderly and efficient transfer of the
Sub-Servicing Agreements to the assuming party.

                  SECTION 3.07. Collection of Certain Mortgage Loan Payments.

                  The Servicer shall diligently collect all payments called for
under the terms and provisions of the Mortgage Loans, and shall, to the extent
such procedures shall be consistent


                                       71
<PAGE>

with this Agreement and the terms and provisions of any applicable insurance
policies provided to the Servicer, follow such collection procedures as it would
follow with respect to mortgage loans comparable to the Mortgage Loans and held
for its own account. Consistent with the foregoing, the Servicer may in its
discretion (i) waive any late payment charge or, if applicable, any penalty
interest, (ii) waive any provisions of any Mortgage Loan requiring the related
Mortgagor to submit to mandatory arbitration with respect to disputes arising
thereunder or (iii) extend the due dates for the Monthly Payments due on a
Mortgage Note for a period of not greater than 180 days; provided, however, that
any extension pursuant to clause (ii) above shall not affect the amortization
schedule of any Mortgage Loan for purposes of any computation hereunder, except
as provided below; provided further that the NIMS Insurer's prior written
consent shall be required for any modification, waiver or amendment if the
aggregate number of outstanding Mortgage Loans which have been modified, waived
or amended exceeds 5% of the number of Mortgage Loans as of the Cut-off Date. In
the event of any such arrangement pursuant to clause (iii) above, the Servicer
shall make timely Advances on such Mortgage Loan during such extension pursuant
to Section 4.03 and in accordance with the amortization schedule of such
Mortgage Loan without modification thereof by reason of such arrangement.
Notwithstanding the foregoing, in the event that any Mortgage Loan is in default
or, in the judgment of the Servicer, such default is reasonably foreseeable, the
Servicer, consistent with the standards set forth in Section 3.01, may also
waive, modify or vary any term of such Mortgage Loan (including modifications
that would change the Mortgage Rate, forgive the payment of principal or
interest or extend the final maturity date of such Mortgage Loan), accept
payment from the related Mortgagor of an amount less than the Stated Principal
Balance in final satisfaction of such Mortgage Loan (such payment, a "Short
Pay-off"), or consent to the postponement of strict compliance with any such
term or otherwise grant indulgence to any Mortgagor without the prior written
consent of the NIMS Insurer.

                  SECTION 3.08. Sub-Servicing Accounts.

                  In those cases where a Sub-Servicer is servicing a Mortgage
Loan pursuant to a Sub-Servicing Agreement, the Sub-Servicer will be required to
establish and maintain one or more accounts (collectively, the "Sub-Servicing
Account"). The Sub-Servicing Account shall be an Eligible Account and shall
comply with all requirements of this Agreement relating to the Collection
Account. The Sub-Servicer shall deposit in the clearing account in which it
customarily deposits payments and collections on mortgage loans in connection
with its mortgage loan servicing activities on a daily basis, and in no event
more than one Business Day after the Sub-Servicer's receipt thereof, all
proceeds of Mortgage Loans received by the Sub-Servicer less its servicing
compensation to the extent permitted by the Sub-Servicing Agreement, and shall
thereafter deposit such amounts in the Sub-Servicing Account, in no event more
than two Business Days after the receipt of such amounts. The Sub-Servicer shall
thereafter deposit such proceeds in the Collection Account or remit such
proceeds to the Servicer for deposit in the Collection Account not later than
two Business Days after the deposit of such amounts in the Sub-Servicing
Account. For purposes of this Agreement, the Servicer shall be deemed to have
received payments on the Mortgage Loans when the Sub-Servicer receives such
payments.



                                       72
<PAGE>

                  SECTION 3.09. Collection of Taxes, Assessments and Similar
                                Items; Servicing Accounts.

                  The Servicer shall establish and maintain, or cause to be
established and maintained, one or more accounts (the "Servicing Accounts"),
into which all collections from the Mortgagors (or related advances from
Sub-Servicers) for the payment of taxes, assessments, hazard insurance premiums
and comparable items for the account of the Mortgagors ("Escrow Payments") shall
be deposited and retained. Servicing Accounts shall be Eligible Accounts. The
Servicer shall deposit in the clearing account in which it customarily deposits
payments and collections on mortgage loans in connection with its mortgage loan
servicing activities on a daily basis, and in no event more than one Business
Day after the Servicer's receipt thereof, all Escrow Payments collected on
account of the Mortgage Loans and shall thereafter deposit such Escrow Payments
in the Servicing Accounts, in no event more than two Business Days after the
receipt of such Escrow Payments, all Escrow Payments collected on account of the
Mortgage Loans for the purpose of effecting the timely payment of any such items
as required under the terms of this Agreement. Withdrawals of amounts from a
Servicing Account may be made only to (i) effect payment of taxes, assessments,
hazard insurance premiums, and comparable items in a manner and at a time that
assures that the lien priority of the Mortgage is not jeopardized (or, with
respect to the payment of taxes, in a manner and at a time that avoids the loss
of the Mortgaged Property due to a tax sale or the foreclosure as a result of a
tax lien); (ii) reimburse the Servicer (or a Sub-Servicer to the extent provided
in the related Sub-Servicing Agreement) out of related collections for any
advances made pursuant to Section 3.01 (with respect to taxes and assessments)
and Section 3.14 (with respect to hazard insurance); (iii) refund to Mortgagors
any sums as may be determined to be overages; (iv) pay interest, if required and
as described below, to Mortgagors on balances in the Servicing Account; or (v)
clear and terminate the Servicing Account at the termination of the Servicer's
obligations and responsibilities in respect of the Mortgage Loans under this
Agreement in accordance with Article IX. In the event the Servicer shall deposit
in a Servicing Account any amount not required to be deposited therein or any
amount previously deposited therein is unpaid by the related Mortgagor's banking
institution, it may at any time withdraw such amount from such Servicing
Account, any provision herein to the contrary notwithstanding. As part of its
servicing duties, the Servicer or Sub-Servicers shall pay to the Mortgagors
interest on funds in the Servicing Accounts, to the extent required by law and,
to the extent that interest earned on funds in the Servicing Accounts is
insufficient, to pay such interest from its or their own funds, without any
reimbursement therefor. The Servicer may pay to itself any excess interest on
funds in the Servicing Accounts, to the extent such action is in conformity with
the servicing standard set forth in Section 3.01, is permitted by law and such
amounts are not required to be paid to Mortgagors or used for any of the other
purposes set forth above.

                  SECTION 3.10. Collection Account and Distribution Account.

                  (a) On behalf of the Trust Fund, the Servicer shall establish
and maintain, or cause to be established and maintained, one or more accounts
(such account or accounts, the "Collection Account"), held in trust for the
benefit of the Trustee and the Certificateholders. On behalf of the Trust Fund,
the Servicer shall deposit or cause to be deposited in the clearing account in
which it customarily deposits payments and collections on mortgage loans in
connection with its mortgage loan servicing activities on a daily basis, and in
no event more than


                                       73
<PAGE>

one Business Day after the Servicer's receipt thereof, and shall thereafter
deposit in the Collection Account, in no event more than two Business Days after
the Servicer's receipt thereof, as and when received or as otherwise required
hereunder, the following payments and collections received or made by it
subsequent to the Cut-off Date (other than in respect of principal or interest
on the Mortgage Loans due on or before the Cut-off Date), or payments (other
than Principal Prepayments) received by it on or prior to the Cut-off Date but
allocable to a Due Period subsequent thereto:

                  (i) all payments on account of principal, including Principal
         Prepayments (but not Prepayment Charges), on the Mortgage Loans;

                  (ii) all payments on account of interest (net of the related
         Servicing Fee) on each Mortgage Loan;

                  (iii) all Insurance Proceeds, Liquidation Proceeds, Subsequent
         Recoveries and condemnation proceeds (other than proceeds collected in
         respect of any particular REO Property and amounts paid in connection
         with a purchase of Mortgage Loans and REO Properties pursuant to
         Section 9.01);

                  (iv) any amounts required to be deposited pursuant to Section
         3.12 in connection with any losses realized on Permitted Investments
         with respect to funds held in the Collection Account;

                  (v) any amounts required to be deposited by the Servicer
         pursuant to the second paragraph of Section 3.14(a) in respect of any
         blanket policy deductibles;

                  (vi) all proceeds of any Mortgage Loan repurchased or
         purchased in accordance with Section 2.03, Section 3.16(c) or Section
         9.01;

                  (vii) all amounts required to be deposited in connection with

         connection with the Principal Prepayment of any of the Mortgage Loans
         and any Servicer Prepayment Charge Payment Amounts.

                  The foregoing requirements for deposit in the Collection
Account shall be exclusive, it being understood and agreed that, without
limiting the generality of the foregoing, payments in the nature of Servicing
Fees, late payment charges, Prepayment Interest Excess, assumption fees,
insufficient funds charges and ancillary income (other than Prepayment Charges)
need not be deposited by the Servicer in the Collection Account and may be
retained by the Servicer as additional compensation. In the event the Servicer
shall deposit in the Collection Account any amount not required to be deposited
therein, it may at any time withdraw such amount from the Collection Account,
any provision herein to the contrary notwithstanding.

                  (b) On behalf of the Trust Fund, the Trustee shall establish
and maintain one or more accounts (such account or accounts, the "Distribution
Account"), held in trust for the benefit of the Certificateholders. On behalf of
the Trust Fund, the Servicer shall deliver to the


                                       74

Trustee in immediately available funds for deposit in the Distribution Account
by 3:00 p.m. New York time (i) on the Servicer Remittance Date, that portion of
Available Funds (calculated without regard to the references in clause (ii) of
the definition thereof to amounts that may be withdrawn from the Distribution
Account) for the related Distribution Date then on deposit in the Collection
Account and the amount of all Prepayment Charges collected by the Servicer in
connection with the Principal Prepayment of any of the Mortgage Loans and any
Servicer Prepayment Charge Payment Amounts then on deposit in the Collection
Account and the amount of any funds reimbursable to an Advancing Person pursuant
to Section 3.26 (unless such amounts are to be remitted in another manner as
specified in the documentation establishing the related Adavance Facility) and
(ii) on each Business Day as of the commencement of which the balance on deposit
in the Collection Account exceeds $75,000 following any withdrawals pursuant to
the next succeeding sentence, the amount of such excess, but only if the
Collection Account constitutes an Eligible Account solely pursuant to clause
(ii) of the definition of "Eligible Account." If the balance on deposit in the
Collection Account exceeds $75,000 as of the commencement of business on any
Business Day and the Collection Account constitutes an Eligible Account solely
pursuant to clause (ii) of the definition of "Eligible Account," the Servicer
shall, by 3:00 p.m. New York time on such Business Day, withdraw from the
Collection Account any and all amounts payable or reimbursable to the Depositor,
the Servicer, the Trustee, NC Capital, the Seller or any Sub-Servicer pursuant
to Section 3.11 and shall pay such amounts to the Persons entitled thereto.

                  (c) Funds in the Collection Account and the Distribution
Account may be invested in Permitted Investments in accordance with the
provisions set forth in Section 3.12. The Servicer shall give written notice to
the Trustee and the NIMS Insurer of the location of the Collection Account
maintained by it when established and prior to any change thereof. The Trustee
shall give notice to the Servicer, the NIMS Insurer and the Depositor of the
location of the Distribution Account when established and prior to any change
thereof.

                  (d) Funds held in the Collection Account at any time may be
delivered by the Servicer to the Trustee for deposit in an account (which may be
the Distribution Account and must satisfy the standards for the Distribution
Account as set forth in the definition thereof) and for all purposes of this
Agreement shall be deemed to be a part of the Collection Account; provided,
however, that the Trustee shall have the sole authority to withdraw any funds
held pursuant to this subsection (d). In the event the Servicer shall deliver to
the Trustee for deposit in the Distribution Account any amount not required to
be deposited therein, it may at any time request that the Trustee withdraw such
amount from the Distribution Account and remit to it any such amount, any
provision herein to the contrary notwithstanding. In addition, the Servicer
shall deliver to the Trustee from time to time for deposit, and the Trustee
shall so deposit, in the Distribution Account:

                  (i) any Advances, as required pursuant to Section 4.03;

                  (ii) any amounts required to be deposited pursuant to Section
         3.23(d) or (f) in connection with any REO Property;

                  (iii) any amounts to be paid in connection with a purchase of
         Mortgage Loans and REO Properties pursuant to Section 9.01; and



                                       75
<PAGE>

                  (iv) any amounts required to be deposited pursuant to Section
         3.24 in connection with any Prepayment Interest Shortfall;

                  (e) The Servicer shall deposit in the Collection Account any
amounts required to be deposited pursuant to Section 3.12(b) in connection with
losses realized on Permitted Investments with respect to funds held in the
Collection Account. The Trustee shall deposit in the Distribution Account any
amounts required to be deposited pursuant to Section 3.12(b) in connection with
losses realized on Permitted Investments with respect to funds held in the
Distribution Account.

                  SECTION 3.11. Withdrawals from the Collection Account and
                                Distribution Account.

                  (a) The Servicer shall, from time to time, make withdrawals
from the Collection Account for any of the following purposes or as described in
Section 4.03:

                  (i) to remit to the Trustee for deposit in the Distribution
         Account the amounts required to be so remitted pursuant to Section
         3.10(b) or permitted to be so remitted pursuant to the first sentence
         of Section 3.10(d);

                  (ii) subject to Section 3.16(d), to reimburse the Servicer for
         unreimbursed Advances, but only to the extent of amounts received which
         represent Late Collections (net of the related Servicing Fees) on
         Mortgage Loans or REO Properties with respect to which such Advances
         were made in accordance with the provisions of Section 4.03;

                  (iii) subject to Section 3.16(d), to pay the Servicer or any
         Sub-Servicer (a) any unpaid Servicing Fees, (b) any unreimbursed
         Servicing Advances with respect to each Mortgage Loan, but only to the
         extent of any Late Collections, received with respect to such Mortgage
         Loan or REO Property and (c) any Nonrecoverable Servicing Advances with
         respect to the final liquidation of a Mortgage Loan, but only to the
         extent that Late Collections, received with respect to such Mortgage
         Loan are insufficient to reimburse the Servicer or any Sub-Servicer for
         Servicing Advances;

                  (iv) to pay to the Servicer as servicing compensation (in
         addition to the Servicing Fee) on the Servicer Remittance Date any
         interest or investment income earned on funds deposited in the
         Collection Account; (v) to pay to the Servicer, the Depositor, NC
         Capital or the Seller, as the case may be, with respect to each
         Mortgage Loan that has previously been purchased or replaced pursuant
         to Section 2.03 or Section 3.16(c) all amounts received thereon
         subsequent to the date of purchase or substitution, as the case may be;

                  (vi) to reimburse the Servicer for any Advance or Servicing
         Advance previously made which the Servicer has determined to be a
         Nonrecoverable Advance in accordance with the provisions of Section
         4.03;



                                       76
<PAGE>

                  (vii) to reimburse the Servicer or the Depositor for expenses
         incurred by or reimbursable to the Servicer or the Depositor, as the
         case may be, pursuant to Section 6.03;

                  (viii) to reimburse the Servicer, the NIMS Insurer or the
         Trustee, as the case may be, for expenses reasonably incurred in
         connection with any breach or defect giving rise to the purchase
         obligation under Section 2.03 of this Agreement, including any expenses
         arising out of the enforcement of the purchase obligation;

                  (ix) to pay, or to reimburse the Servicer for Servicing
         Advances in respect of, expenses incurred in connection with any
         Mortgage Loan pursuant to Section 3.16(b);

                  (x) to withdraw amounts deposited therein in error;

                  (xi) to pay itself any Prepayment Interest Excess (to the
         extent not otherwise retained);

                  (xii) to withdraw amounts deposited therein in error; and

                  (xiii) to clear and terminate the Collection Account pursuant
         to Section 9.01.

                  The Servicer shall keep and maintain separate accounting, on a
Mortgage Loan-by-Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Collection Account, to the extent held by or on behalf of
it, pursuant to subclauses (ii), (iii), (iv), (v), (vi), (viii) and (ix) above.
The Servicer shall provide written notification to the Trustee and the NIMS
Insurer on or prior to the next succeeding Servicer Remittance Date, upon making
any withdrawals from the Collection Account pursuant to subclauses (iii(c)) and
(vi) above; provided that an Officer's Certificate in the form described under
Section 4.03(d) shall suffice for such written notification to the Trustee
respect of clause (vi) hereof.

                  (b) The Trustee shall, from time to time, make withdrawals
from the Distribution Account, for any of the following purposes, without
priority:

                  (i) to make distributions to Certificateholders in accordance
         with Section 4.01;

                  (ii) to pay itself the Trustee Fee and any Extraordinary Trust
         Fund Expenses pursuant to Section 8.05;

                  (iii) to pay the Credit Risk Manager the Credit Risk Manager;

                  (iv) to pay to itself on each Distribution Date any interest
         or investment income earned on funds deposited in the Distribution
         Account pursuant to Section 3.12(b);

                  (v) to reimburse itself pursuant to Section 7.02;

                  (vi) to pay any amounts in respect of taxes pursuant to
         Section 10.01(g)(iii);



                                       77
<PAGE>

                  (vii) to pay to an Advancing Person reimbursements for
         Advances and/or Servicing Advances pursuant to Section 3.26; and

                  (viii) to clear and terminate the Distribution Account
         pursuant to Section 9.01.

                  The foregoing requirements for withdrawal from the
Distribution Account shall be exclusive. In the event the Trustee shall deposit
in the Distribution Account any amount not required to be deposited therein, it
may at any time withdraw such amount from the Distribution Account, any
provision herein to the contrary notwithstanding.

                  SECTION 3.12. Investment of Funds in the Collection Account
                                and the Distribution Account.

                  (a) The Servicer may direct any depository institution
maintaining the Collection Account and any REO Account and the Trustee may
direct any depository institution maintaining the Distribution Account (each,
for purposes of this Section 3.12, an "Investment Account") to invest the funds
in such Investment 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 Trustee is the obligor thereon or if such investment is managed or
advised by a Person other than the Trustee or an Affiliate of the Trustee, 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 Trustee is the obligor
thereon or if such investment is managed or advised by the Trustee or any
Affiliate. All such Permitted Investments shall be held to maturity, unless
payable on demand. Any investment of funds in an Investment Account shall be
made in the name of the Trustee (in its capacity as such), or in the name of a
nominee of the Trustee. The Trustee shall be entitled to sole possession (except
with respect to investment direction of funds held in the Collection Account or
any REO Account and any income and gain realized thereon) over each such
investment, and any certificate or other instrument evidencing any such
investment shall be delivered directly to the Trustee or its agent, together
with any document of transfer necessary to transfer title to such investment to
the Trustee or its nominee. In the event amounts on deposit in an Investment
Account are at any time invested in a Permitted Investment payable on demand,
the Trustee shall:

                  (x) consistent with any notice required to be given
thereunder, demand that payment thereon be made on the last day such Permitted
Investment may otherwise mature hereunder in an amount equal to the lesser of
(1) all amounts then payable thereunder and (2) the amount required to be
withdrawn on such date; and

                  (y) demand payment of all amounts due thereunder promptly upon
determination by a Responsible Officer of the Trustee that such Permitted
Investment would not constitute a Permitted Investment in respect of funds
thereafter on deposit in the Investment Account.

                  (b) All income and gain realized from the investment of funds
deposited in the Collection Account and any REO Account held by or on behalf of
the Servicer shall be for the


                                       78
<PAGE>

benefit of the Servicer and shall be subject to its withdrawal in accordance
with Section 3.11 or Section 3.23, as applicable. All income and gain realized
from the investment of funds deposited in the Distribution Account held by or on
behalf of the Trustee shall be for the benefit of the Trustee and shall be
subject to its withdrawal in accordance with Section 3.11. The Servicer shall
deposit in the Collection Account and any REO Account, as applicable, the amount
of any loss of principal incurred in respect of any such Permitted Investment
made with funds in such accounts immediately upon realization of such loss. The
Trustee shall deposit in the Distribution Account the amount of any loss of
principal incurred in respect of any such Permitted Investment made with funds
in such accounts immediately upon realization of such loss.

                  (c) Except as otherwise expressly provided in this Agreement,
if any default occurs in the making of a payment due under any Permitted
Investment, or if a default occurs in any other performance required under any
Permitted Investment, the Trustee may and, subject to Section 8.01 and Section
8.02(a)(v), upon the request of the NIMS Insurer or the Holders of Certificates
representing more than 50% of the Voting Rights allocated to any Class of
Certificates, shall take such action as may be appropriate to enforce such
payment or performance, including the institution and prosecution of appropriate
proceedings.

                  SECTION 3.13. [Reserved].

                  SECTION 3.14. Maintenance of Hazard Insurance and Errors and
                                Omissions and Fidelity Coverage.

                  (a) The Servicer shall cause to be maintained for each
Mortgage Loan fire insurance with extended coverage on the related Mortgaged
Property in an amount which is at least equal to the least of the (i) current
Stated Principal Balance of such Mortgage Loan (ii) the amount necessary to
fully compensate for any damage or loss to the improvements that are a part of
such property on a replacement cost basis and (iii) the maximum insurable value
of the improvements which are part of such mortgaged property, in each case in
an amount not less than such amount as is necessary to avoid the application of
any coinsurance clause contained in the related hazard insurance policy. The
Servicer shall also cause to be maintained fire insurance with extended coverage
on each REO Property in an amount which is at least equal to the least of (i)
the maximum insurable value of the improvements which are a part of such
property, (ii) the outstanding Stated Principal Balance of the related Mortgage
Loan at the time it became an REO Property and (iii) the maximum insurable value
of the improvements which are part of such REO Property. The Servicer will
comply in the performance of this Agreement with all reasonable rules and
requirements of each insurer under any such hazard policies. Any amounts to be
collected by the Servicer under any such policies (other than amounts to be
applied to the restoration or repair of the property subject to the related
Mortgage or amounts to be released to the Mortgagor in accordance with the
procedures that the Servicer would follow in servicing loans held for its own
account, subject to the terms and conditions of the related Mortgage and
Mortgage Note) shall be deposited in the Collection Account, subject to
withdrawal pursuant to Section 3.11, if received in respect of a Mortgage Loan,
or in the REO Account, subject to withdrawal pursuant to Section 3.23, if
received in respect of an REO Property. Any cost incurred by the Servicer in
maintaining any such insurance shall not, for the purpose of calculating
distributions to Certificateholders, be added to the unpaid Stated Principal
Balance of the related Mortgage Loan, notwithstanding that the terms of such
Mortgage Loan so permit. It is


                                       79
<PAGE>

understood and agreed that no earthquake or other additional insurance is to be
required of any Mortgagor other than pursuant to such applicable laws and
regulations as shall at any time be in force and as shall require such
additional insurance. If the Mortgaged Property or REO Property is at any time
in an area identified in the Federal Register by the Federal Emergency
Management Agency as having special flood hazards and flood insurance has been
made available, the Servicer will cause to be maintained a flood insurance
policy in respect thereof. Such flood insurance shall be in an amount equal to
the least of (i) the unpaid Stated Principal Balance of the related Mortgage
Loan, (ii) the maximum amount of such insurance available for the related
Mortgaged Property under the national flood insurance program (assuming that the
area in which such Mortgaged Property is located is participating in such
program) and (iii) the maximum insurable value of the improvements which are
part of such Mortgaged Property.

                  In the event that the Servicer shall obtain and maintain a
blanket policy with an insurer having a General Policy Rating of A:X or better
in Best's Key Rating Guide (or such other rating that is comparable to such
rating) or otherwise acceptable to Fannie Mae or Freddie Mac insuring against
hazard losses on all of the Mortgage Loans, it shall conclusively be deemed to
have satisfied its obligations as set forth in the first two sentences of this
Section 3.14, it being understood and agreed that such policy may contain a
deductible clause, in which case the Servicer shall, in the event that there
shall not have been maintained on the related Mortgaged Property or REO Property
a policy complying with the first two sentences of this Section 3.14, and there
shall have been one or more losses which would have been covered by such policy,
deposit to the Collection Account from its own funds the amount not otherwise
payable under the blanket policy because of such deductible clause. In
connection with its activities as administrator and servicer of the Mortgage
Loans, the Servicer agrees to prepare and present, on behalf of itself, the
Trustee and Certificateholders, claims under any such blanket policy in a timely
fashion in accordance with the terms of such policy.

                  (b) The Servicer shall keep in force during the term of this
Agreement a policy or policies of insurance covering errors and omissions for
failure in the performance of the Servicer's obligations under this Agreement,
which policy or policies shall be in such form and amount that would meet the
requirements of Fannie Mae or Freddie Mac if it were the purchaser of the
Mortgage Loans, unless the Servicer has obtained a waiver of such requirements
from Fannie Mae or Freddie Mac. The Servicer shall provide the Trustee and the
NIMS Insurer, upon request, with copies of such insurance policies and fidelity
bond. The Servicer shall also maintain a fidelity bond in the form and amount
that would meet the requirements of Fannie Mae or Freddie Mac, unless the
Servicer has obtained a waiver of such requirements from Fannie Mae or Freddie
Mac. The Servicer shall be deemed to have complied with this provision if an
Affiliate of the Servicer has such errors and omissions and fidelity bond
coverage and, by the terms of such insurance policy or fidelity bond, the
coverage afforded thereunder extends to the Servicer. Any such errors and
omissions policy and fidelity bond shall by its terms not be cancelable or
materially modifiable without thirty days' prior written notice to the Trustee
and the NIMS Insurer. The Servicer shall also cause each Sub-Servicer to
maintain a policy of insurance covering errors and omissions and a fidelity bond
which would meet such requirements.

                  SECTION 3.15. Enforcement of Due-On-Sale Clauses; Assumption
                                Agreements.

                  The Servicer will, to the extent it has knowledge of any
conveyance or prospective conveyance of any Mortgaged Property by any Mortgagor
(whether by absolute conveyance or by contract of sale, and whether or not the
Mortgagor remains or is to remain liable under the Mortgage Note and/or the
Mortgage), exercise its rights to accelerate the maturity of such Mortgage Loan
under the "due-on-sale" clause, if any, applicable thereto; provided, however,
that the Servicer shall not be required to take such action if in its sole
business judgment the Servicer believes it is not in the best interests of the
Trust Fund and shall not exercise any such rights if prohibited by law from
doing so. If the Servicer reasonably believes it is unable under applicable law
to enforce such "due-on-sale" clause, or if any of the other conditions set
forth in the proviso to the preceding sentence apply, the Servicer will enter
into an assumption and modification agreement from or with the person to whom
such property has been conveyed or is proposed to be conveyed, pursuant to which
such person becomes liable under the Mortgage Note and, to the extent permitted
by applicable state law, the Mortgagor remains liable thereon. The Servicer is
also authorized to enter into a substitution of liability agreement with such
person, pursuant to which the original Mortgagor is released from liability and
such person is substituted as the Mortgagor and becomes liable under the
Mortgage Note; provided that no such substitution shall be effective unless such
person satisfies the underwriting criteria of the Servicer and has a credit risk
rating at least equal to that of the original Mortgagor. In connection with any
assumption or substitution, the Servicer shall apply such underwriting standards
and follow such practices and procedures as shall be normal and usual in its
general mortgage servicing activities and as it applies to other mortgage loans
owned solely by it. The Servicer shall not take or enter into any assumption and
modification agreement, however, unless (to the extent practicable in the
circumstances) it shall have received confirmation, in writing, of the continued
effectiveness of any applicable hazard insurance policy. Any fee collected by
the Servicer in respect of an assumption, modification or substitution of
liability agreement shall be retained by the Servicer as additional servicing
compensation. In connection with any such assumption, no material term of the
Mortgage Note (including but not limited to the related Mortgage Rate and the
amount of the Monthly Payment) may be amended or modified, except as otherwise
required pursuant to the terms thereof. The Servicer shall notify the Trustee
and the Custodian that any such substitution, modification or assumption
agreement has been completed by forwarding to the Custodian the executed
original of such substitution, modification or assumption agreement, which
document shall be added to the related Mortgage File and shall, for all
purposes, be considered a part of such Mortgage File to the same extent as all
other documents and instruments constituting a part thereof.

                  Notwithstanding the foregoing paragraph or any other provision
of this Agreement, the Servicer shall not be deemed to be in default, breach or
any other violation of its obligations hereunder by reason of any assumption of
a Mortgage Loan by operation of law or by the terms of the Mortgage Note or any
assumption which the Servicer may be restricted by law from preventing, for any
reason whatever. For purposes of this Section 3.15, the term "assumption" is
deemed to also include a sale (of the Mortgaged Property) subject to the
Mortgage that is not accompanied by an assumption or substitution of liability
agreement.

                  SECTION 3.16. Realization Upon Defaulted Mortgage Loans.

                  (a) The Servicer shall use its best efforts, consistent with
the servicing standards set forth in Section 3.01, to foreclose upon or
otherwise comparably convert the ownership of properties securing such of the
Mortgage Loans as come into and continue in default and as to which no
satisfactory arrangements can be made for collection of delinquent payments
pursuant to Section 3.07. The Servicer shall be responsible for all costs and
expenses incurred by it in any such proceedings; provided, however, that such
costs and expenses will be recoverable as Servicing Advances by the Servicer as
contemplated in Section 3.11 and Section 3.23. The foregoing is subject to the
provision that, in any case in which a Mortgaged Property shall have suffered
damage from an Uninsured Cause, the Servicer shall not be required to expend its
own funds toward the restoration of such property unless it shall determine in
its discretion that such restoration will increase the proceeds of liquidation
of the related Mortgage Loan after reimbursement to itself for such expenses.

                  (b) Notwithstanding the foregoing provisions of this Section
3.16 or any other provision of this Agreement, with respect to any Mortgage Loan
as to which the Servicer has received actual notice of, or has actual knowledge
of, the presence of any toxic or hazardous substance on the related Mortgaged
Property, the Servicer shall not, on behalf of the Trustee, either (i) obtain
title to such Mortgaged Property as a result of or in lieu of foreclosure or
otherwise, or (ii) otherwise acquire possession of, or take any other action
with respect to, such Mortgaged Property, if, as a result of any such action,
the Trustee, the Trust Fund or the Certificateholders would be considered to
hold title to, to be a "mortgagee-in-possession" of, or to be an "owner" or
"operator" of such Mortgaged Property within the meaning of the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended from
time to time, or any comparable law, unless the Servicer has also previously
determined, based on its reasonable judgment and a report prepared by a Person
who regularly conducts environmental audits using customary industry standards,
that:

                  (1) such Mortgaged Property is in compliance with applicable
environmental laws or, if not, that it would be in the best economic interest of
the Trust Fund to take such actions as are necessary to bring the Mortgaged
Property into compliance therewith; and

                  (2) there are no circumstances present at such Mortgaged
Property relating to the use, management or disposal of any hazardous
substances, hazardous materials, hazardous wastes, or petroleum-based materials
for which investigation, testing, monitoring, containment, clean-up or
remediation could be required under any federal, state or local law or
regulation, or that if any such materials are present for which such action
could be required, that it would be in the best economic interest of the Trust
Fund to take such actions with respect to the affected Mortgaged Property.

                  Notwithstanding the foregoing, if such environmental audit
reveals, or if the Servicer has actual knowledge or notice, that such Mortgaged
Property contains such toxic or hazardous wastes or substances, the Servicer
shall not foreclose or accept a deed in lieu of foreclosure without the prior
written consent of the NIMS Insurer.



                                       82
<PAGE>

                  The cost of the environmental audit report contemplated by
this Section 3.16 shall be advanced by the Servicer, subject to the Servicer's
right to be reimbursed therefor from the Collection Account as provided in
Section 3.11(a)(ix), such right of reimbursement being prior to the rights of
Certificateholders to receive any amount in the Collection Account received in
respect of the affected Mortgage Loan or other Mortgage Loans.

                  If the Servicer determines, as described above, that it is in
the best economic interest of the Trust Fund to take such actions as are
necessary to bring any such Mortgaged Property into compliance with applicable
environmental laws, or to take such action with respect to the containment,
clean-up or remediation of hazardous substances, hazardous materials, hazardous
wastes or petroleum-based materials affecting any such Mortgaged Property, then
the Servicer shall take such action as it deems to be in the best economic
interest of the Trust Fund; provided that any amounts disbursed by the Servicer
pursuant to this Section 3.16(b) shall constitute Servicing Advances, subject to
Section 4.03(d). The cost of any such compliance, containment, cleanup or
remediation shall be advanced by the Servicer, subject to the Servicer's right
to be reimbursed therefor from the Collection Account as provided in Section
3.11(a)(iii) and (a)(ix), such right of reimbursement being prior to the rights
of Certificateholders to receive any amount in the Collection Account received
in respect of the affected Mortgage Loan or other Mortgage Loans.

                  (c) The Servicer or the NIMS Insurer may, at the option of
each, purchase a Mortgage Loan which has become 90 or more days delinquent or
for which the Servicer has accepted a deed in lieu of foreclosure. Prior to
purchase pursuant to this Section 3.16(c), the Servicer shall be required to
continue to make Advances pursuant to Section 4.03. The Servicer or the NIMS
Insurer shall not use any procedure in selecting Mortgage Loans to be
repurchased which is materially adverse to the interests of the
Certificateholders. The Servicer or the NIMS Insurer shall purchase such
delinquent Mortgage Loan at a price equal to the Purchase Price of such Mortgage
Loan. Any such purchase of a Mortgage Loan pursuant to this Section 3.16(c)(i)
shall be accomplished by remittance to the Servicer for deposit in the
Collection Account of the amount of the Purchase Price. Notwithstanding the
foregoing, the Servicer or the NIM Insurer shall purchase Mortgage Loans that
are delinquent the greatest number of days before it may purchase any that are
delinquent any fewer number of days. The Trustee shall immediately effectuate
the conveyance of such delinquent Mortgage Loan to the Servicer or the NIMS
Insurer, as applicable, to the extent necessary to vest in the Servicer or the
NIMS Insurer, as applicable, title to such Mortgage Loan, including the prompt
delivery of all documentation to the Servicer or the NIMS Insurer, as
applicable.

                  (d) Proceeds received in connection with any Final Recovery
Determination, as well as any recovery resulting from a partial collection of
Insurance Proceeds, Liquidation Proceeds or condemnation proceeds, in respect of
any Mortgage Loan, will be applied in the following order of priority: first, to
unpaid Servicing Fees; second, to reimburse the Servicer or any Sub-Servicer for
any related unreimbursed Servicing Advances pursuant to Section 3.11(a)(iii) and
Advances pursuant to Section 3.11(a)(ii); third, to accrued and unpaid interest
on the Mortgage Loan, to the date of the Final Recovery Determination, or to the
Due Date prior to the Distribution Date on which such amounts are to be
distributed if not in connection with a Final Recovery Determination; and
fourth, as a recovery of principal of the Mortgage Loan. The


                                       83
<PAGE>

portion of the recovery so allocated to unpaid Servicing Fees shall be
reimbursed to the Servicer or any Sub-Servicer pursuant to Section 3.11(a)(iii).

                  SECTION 3.17. Trustee to Cooperate; Release of Mortgage Files.

                  (a) Upon the payment in full of any Mortgage Loan, or the
receipt by the Servicer of a notification that payment in full shall be escrowed
in a manner customary for such purposes, the Servicer shall deliver to the
Trustee (or the Custodian on its behalf), in written (with two executed copies)
or electronic format, a Request for Release in the form of Exhibit E (which
certification shall include a statement to the effect that all amounts received
or to be received in connection with such payment which are required to be
deposited in the Collection Account pursuant to Section 3.10 have been or will
be so deposited) signed by a Servicing Officer (or in a mutually agreeable
electronic format that will, in lieu of a signature on its face, originate from
a Servicing Officer) and shall request delivery to it of the Mortgage File. Upon
receipt of such certification and request, the Custodian shall, within three
Business Days, release and send by overnight mail, the related Mortgage File to
the Servicer and the Servicer is authorized to cause the removal from the
registration on the MERS(R) System of any such Mortgage Loan, if applicable. The
Trustee agrees to indemnify the Servicer, out of its own funds, for any loss,
liability or expense (other than special, indirect, punitive or consequential
damages which will not be paid by the Trustee) incurred by the Servicer as a
proximate result of the Trustee's breach of its obligations pursuant to this
Section 3.17. Except as otherwise provided herein, expenses incurred in
connection with any instrument of satisfaction or deed of reconveyance shall be
chargeable to the Collection Account or the Distribution Account.

                  (b) From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan, including, for this purpose, collection under
any insurance policy relating to the Mortgage Loans, the Custodian shall, upon
any request made by or on behalf of the Servicer and delivery to the Custodian,
in written or electronic format, of a Request for Release in the form of Exhibit
E, release the related Mortgage File within three Business Days to the Servicer,
and shall, at the direction of the Servicer, execute such documents as shall be
necessary to the prosecution of any such proceedings. Such Request for Release
shall obligate the Servicer to return each and every document previously
requested from the Mortgage File to the Custodian when the need therefor by the
Servicer no longer exists, unless the Mortgage Loan has been liquidated and the
Liquidation Proceeds relating to the Mortgage Loan have been deposited in the
Collection Account or the Mortgage File or such document has been delivered to
an attorney, or to a public trustee or other public official as required by law,
for purposes of initiating or pursuing legal action or other proceedings for the
foreclosure of the Mortgaged Property either judicially or non-judicially, and
the Servicer has delivered, or caused to be delivered, to the Custodian an
additional Request for Release certifying as to such liquidation or action or
proceedings. Upon the request of the Trustee, the Servicer shall provide notice
to the Trustee of the name and address of the Person to which such Mortgage File
or such document was delivered and the purpose or purposes of such delivery.
Upon receipt of a Request for Release, in written or electronic format from, a
Servicing Officer stating that such Mortgage Loan was liquidated and that all
amounts received or to be received in connection with such liquidation that are
required to be deposited into the Collection Account have been so deposited, or
that such Mortgage Loan has become an REO Property, any outstanding Requests for
Release with respect to such Mortgage Loan shall be released by the Custodian to
the Servicer or its designee.



                                       84
<PAGE>

                  (c) Upon written certification of a Servicing Officer, the
Trustee shall execute and deliver to the Servicer or the Sub-Servicer, as the
case may be, any court pleadings, requests for trustee's sale or other documents
necessary to the foreclosure or trustee's sale in respect of a Mortgaged
Property or to any legal action brought to obtain judgment against any Mortgagor
on the Mortgage Note or Mortgage or to obtain a deficiency judgment, or to
enforce any other remedies or rights provided by the Mortgage Note or Mortgage
or otherwise available at law or in equity. Each such certification shall
include a request that such pleadings or documents be executed by the Trustee
and a statement as to the reason such documents or pleadings are required and
that the execution and delivery thereof by the Trustee will not invalidate or
otherwise affect the lien of the Mortgage, except for the termination of such a
lien upon completion of the foreclosure or trustee's sale.

                  SECTION 3.18. Servicing Compensation.

                  As compensation for the activities of the Servicer hereunder,
the Servicer shall be entitled to the Servicing Fee with respect to each
Mortgage Loan payable solely from payments of interest in respect of such
Mortgage Loan, subject to Section 3.24. In addition, the Servicer shall be
entitled to recover unpaid Servicing Fees out of Insurance Proceeds, Liquidation
Proceeds and condemnation proceeds to the extent permitted by Section
3.11(a)(iii) and out of amounts derived from the operation and sale of an REO
Property to the extent permitted by Section 3.23. Except as provided in Section
6.04, the right to receive the Servicing Fee may not be transferred in whole or
in part except in connection with the transfer of all of the Servicer's
responsibilities and obligations under this Agreement; provided, however, that
the Servicer may pay from the Servicing Fee any amounts due to a Sub-Servicer
pursuant to a Sub-Servicing Agreement entered into under Section 3.02. As part
of its servicing compensation, the Servicer shall also be entitled to Prepayment
Interest Excess.

                  Additional servicing compensation in the form of assumption or
modification fees, late payment charges, insufficient funds charges, ancillary
income or otherwise (subject to Section 3.24 and other than Prepayment Charges)
shall be retained by the Servicer only to the extent such fees or charges are
received by the Servicer. The Servicer shall also be entitled pursuant to
Section 3.11(a)(iv) to withdraw from the Collection Account and pursuant to
Section 3.23(b) to withdraw from any REO Account, as additional servicing
compensation, interest or other income earned on deposits therein, subject to
Section 3.12 and Section 3.24. The Servicer shall be required to pay all
expenses incurred by it in connection with its servicing activities hereunder
(including premiums for the insurance required by Section 3.14, to the extent
such premiums are not paid by the related Mortgagors or by a Sub-Servicer and
servicing compensation of each Sub-Servicer) and shall not be entitled to
reimbursement therefor except as specifically provided herein.

                  SECTION 3.19. Reports to the Trustee; Collection Account
                                Statements.

                  Not later than twenty days after each Distribution Date, the
Servicer shall forward, upon request, to the Trustee, the NIMS Insurer and the
Depositor the most current available bank statement for the Collection Account.
Copies of such statement shall be provided by the Trustee to any
Certificateholder and to any Person identified to the Trustee as a


                                       85
<PAGE>

prospective transferee of a Certificate, upon request at the expense of the
requesting party; provided that such statement is delivered by the Servicer to
the Trustee.

                  SECTION 3.20. Statement as to Compliance.

The Servicer will deliver to the Trustee, the NIMS Insurer and the Depositor not
later than March 15th of each calendar year (beginning in 2006), an Officer's
Certificate, in a form similar to Exhibit L attached hereto as agreed upon by
the parties hereto, stating, as to each signatory thereof, that (i) a review of
the activities of the Servicer during the preceding year and of performance
under this Agreement has been made under such officers' supervision and (ii) to
the best of such officers' knowledge, based on such review, the Servicer has
fulfilled all of its obligations under this Agreement throughout such year, or,
if there has been a default in the fulfillment of any such obligation,
specifying each such default known to such officer and the nature and status
thereof. Copies of any such statement shall be provided by the Trustee to any
Certificateholder and to any Person identified to the Trustee as a prospective
transferee of a Certificate, upon request at the expense of the requesting
party; provided that such statement is delivered by the Servicer to the Trustee.
In addition to the foregoing, the Servicer will, to the extent reasonable,
provide any other servicing information required by the Commission pursuant to
applicable law.


                  SECTION 3.21. Independent Public Accountants' Servicing
                                Report.

                  Not later than March 15th of each calendar year (beginning in
2006), the Servicer, at its expense, shall cause a nationally recognized firm of
independent certified public accountants to furnish to the Servicer a report
stating that (i) it has obtained a letter of representation regarding certain
matters from the management of the Servicer which includes an assertion that the
Servicer has complied with certain minimum residential mortgage loan servicing
standards, identified in the Uniform Single Attestation Program for Mortgage
Bankers established by the Mortgage Bankers Association of America, with respect
to the servicing of residential mortgage loans during the most recently
completed calendar year and (ii) on the basis of an examination conducted by
such firm in accordance with standards established by the American Institute of
Certified Public Accountants, such representation is fairly stated in all
material respects, subject to such exceptions and other qualifications that may
be appropriate. In rendering its report such firm may rely, as to matters
relating to the direct servicing of residential mortgage loans by Sub-Servicers,
upon comparable reports of firms of independent certified public accountants
rendered on the basis of examinations conducted in accordance with the same
standards (rendered within one year of such report) with respect to those
Sub-Servicers. Immediately upon receipt of such report, the Servicer shall
furnish a copy of such report to the Trustee, the NIMS Insurer and the
Depositor. Copies of such statement shall be provided by the Trustee to any
Certificateholder upon request at the expense of the requesting party, provided
that such statement is delivered by the Servicer to the Trustee.

                  SECTION 3.22. Access to Certain Documentation.

                  The Servicer shall provide to the Office of Thrift
Supervision, the FDIC, and any other federal or state banking or insurance
regulatory authority that may exercise authority over


                                       86
<PAGE>

any Certificateholder, access to the documentation in the Servicer's possession
regarding the Mortgage Loans required by applicable laws and regulations. Such
access shall be afforded without charge, but only upon reasonable request and
during normal business hours at the offices of the Servicer designated by it. In
addition, access to the documentation in the Servicer's possession regarding the
Mortgage Loans will be provided to the Trustee on behalf of the
Certificateholders and the NIMS Insurer upon reasonable request during normal
business hours at the offices of the Servicer designated by it at the expense of
the Person requesting such access; provided however that providing access to
such Person will not violate any applicable laws. Nothing in this Section shall
limit the obligation of the Servicer to observe any applicable law prohibiting
disclosure of information regarding the Mortgagors (absent proof that it is in
compliance with applicable law) and the failure of the Servicer to provide
access as provided in this Section as a result of such obligation shall not
constitute a breach of this Section. Nothing in this Section 3.22 shall require
the Servicer to collect, create, collate or otherwise generate any information
that it does not generate in its usual course of business. The Servicer shall
not be required to make copies of or ship documents to any party unless
provisions have been made for the reimbursement of the costs thereof.

                  SECTION 3.23. Title, Management and Disposition of REO
                                Property.

                  (a) The deed or certificate of sale of any REO Property shall,
subject to applicable laws, be taken in the name of the Trustee, or its nominee,
in trust for the benefit of the Certificateholders. The Servicer, on behalf of
REMIC I, shall sell any REO Property as soon as practical and in any event no
later than the end of the third full taxable year after the taxable year in
which such REMIC acquires ownership of such REO Property for purposes of Section
860G(a)(8) of the Code or request from the Internal Revenue Service, no later
than 60 days before the day on which the three-year grace period would otherwise
expire, an extension of such three-year period, unless the Servicer shall have
delivered to the Trustee and the NIMS Insurer an Opinion of Counsel acceptable
to the NIMS Insurer and addressed to the Trustee, the NIMS Insurer and the
Depositor, to the effect that the holding by the REMIC of such REO Property
subsequent to three years after its acquisition will not result in the
imposition on the REMIC of taxes on "prohibited transactions" thereof, as
defined in Section 860F of the Code, or cause any of the REMICs created
hereunder to fail to qualify as a REMIC under Federal law at any time that any
Certificates are outstanding. The Servicer shall manage, conserve, protect and
operate each REO Property for the Certificateholders solely for the purpose of
its prompt disposition and sale in a manner which does not cause such REO
Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code or result in the receipt by any of the REMICs
created hereunder of any "income from non-permitted assets" within the meaning
of Section 860F(a)(2)(B) of the Code, or any "net income from foreclosure
property" which is subject to taxation under the REMIC Provisions.

                  (b) The Servicer shall separately account for all funds
collected and received in connection with the operation of any REO Property and
shall establish and maintain, or cause to be established and maintained, with
respect to REO Properties an account held in trust for the Trustee for the
benefit of the Certificateholders (the "REO Account"), which shall be an
Eligible Account. The Servicer shall be permitted to allow the Collection
Account to serve as the REO Account, subject to separate ledgers for each REO
Property. The Servicer shall be entitled to retain or withdraw any interest
income paid on funds deposited in the REO Account.



                                       87
<PAGE>

                  (c) The Servicer shall have full power and authority, subject
only to the specific requirements and prohibitions of this Agreement, to do any
and all things in connection with any REO Property as are consistent with the
manner in which the Servicer manages and operates similar property owned by the
Servicer or any of its Affiliates, all on such terms and for such period
(subject to the requirement of prompt disposition set forth in Section 3.23(a))
as the Servicer deems to be in the best interests of Certificateholders. In
connection therewith, the Servicer shall deposit, or cause to be deposited in
the clearing account in which it customarily deposits payments and collections
on mortgage loans in connection with its mortgage loan servicing activities on a
daily basis, and in no event more than one Business Day after the Servicer's
receipt thereof, and shall thereafter deposit in the REO Account, in no event
more than two Business Days after the Servicer's receipt thereof, all revenues
received by it with respect to an REO Property and shall withdraw therefrom
funds necessary for the proper operation, management and maintenance of such REO
Property including, without limitation:

                  (i) all insurance premiums due and payable in respect of such
         REO Property;

                  (ii) all real estate taxes and assessments in respect of such
         REO Property that may result in the imposition of a lien thereon; and

                  (iii) all costs and expenses necessary to maintain such REO
         Property.

                  To the extent that amounts on deposit in the REO Account with
respect to an REO Property are insufficient for the purposes set forth in
clauses (i) through (iii) above with respect to such REO Property, the Servicer
shall advance from its own funds such amount as is necessary for such purposes
if, but only if, the Servicer would make such advances if the Servicer owned the
REO Property and if in the Servicer's judgment, the payment of such amounts will
be recoverable from the rental or sale of the REO Property.

                  Notwithstanding the foregoing, neither the Servicer nor the
Trustee shall:

                  (a) authorize the Trust Fund to enter into, renew or extend
any New Lease with respect to any REO Property, if the New Lease by its terms
will give rise to any income that does not constitute Rents from Real Property;

                  (b) authorize any amount to be received or accrued under any
New Lease other than amounts that will constitute Rents from Real Property;

                  (c) authorize any construction on any REO Property, other than
the completion of a building or other improvement thereon, and then only if more
than ten percent of the construction of such building or other improvement was
completed before default on the related Mortgage Loan became imminent, all
within the meaning of Section 856(e)(4)(B) of the Code; or

                  (d) authorize any Person to Directly Operate any REO Property
on any date more than 90 days after its date of acquisition by the Trust Fund;

                  unless, in any such case, the Servicer has obtained an Opinion
of Counsel, provided to the Trustee and the NIMS Insurer, to the effect that
such action will not cause such


                                       88
<PAGE>

REO Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code at any time that it is held by the REMIC, in
which case the Servicer may take such actions as are specified in such Opinion
of Counsel.

                  The Servicer may contract with any Independent Contractor for
the operation and management of any REO Property; provided that:

                  (i) the terms and conditions of any such contract shall not be
         inconsistent herewith;

                  (ii) any such contract shall require, or shall be administered
         to require, that the Independent Contractor pay all costs and expenses
         incurred in connection with the operation and management of such REO
         Property, including those listed above and remit all related revenues
         (net of such costs and expenses) to the Servicer as soon as
         practicable, but in no event later than thirty days following the
         receipt thereof by such Independent Contractor;

                  (iii)none of the provisions of this Section 3.23(c) relating
         to any such contract or to actions taken through any such Independent
         Contractor shall be deemed to relieve the Servicer of any of its duties
         and obligations to the Trustee on behalf of the Certificateholders with
         respect to the operation and management of any such REO Property; and
         the Servicer shall be obligated with respect thereto to the same extent
         as if it alone were performing all duties and obligations in connection
         with the operation and management of such REO Property.

                  The Servicer shall be entitled to enter into any agreement
with any Independent Contractor performing services for it related to its duties
and obligations hereunder for indemnification of the Servicer by such
Independent Contractor, and nothing in this Agreement shall be deemed to limit
or modify such indemnification. The Servicer shall be solely liable for all fees
owed by it to any such Independent Contractor, irrespective of whether the
Servicer's compensation pursuant to Section 3.18 is sufficient to pay such fees;
provided, however, that to the extent that any payments made by such Independent
Contractor would constitute Servicing Advances if made by the Servicer, such
amounts shall be reimbursable as Servicing Advances made by the Servicer.

                  (d) In addition to the withdrawals permitted under Section
3.23(c), the Servicer may from time to time make withdrawals from the REO
Account for any REO Property: (i) to pay itself or any Sub-Servicer unpaid
Servicing Fees in respect of the related Mortgage Loan; and (ii) to reimburse
itself or any Sub-Servicer for unreimbursed Servicing Advances and Advances made
in respect of such REO Property or the related Mortgage Loan. On the Servicer
Remittance Date, the Servicer shall withdraw from each REO Account maintained by
it and deposit into the Distribution Account in accordance with Section
3.10(d)(ii), for distribution on the related Distribution Date in accordance
with Section 4.01, the income from the related REO Property received during the
prior calendar month, net of any withdrawals made pursuant to Section 3.23(c) or
this Section 3.23(d).

                  (e) Subject to the time constraints set forth in Section
3.23(a), each REO Disposition shall be carried out by the Servicer at such price
and upon such terms and conditions


                                       89
<PAGE>

as the Servicer shall deem necessary or advisable, as shall be normal and usual
in the servicing standards set forth in Section 3.01.

                  (f) The proceeds from the REO Disposition, net of any amount
required by law to be remitted to the Mortgagor under the related Mortgage Loan
and net of any payment or reimbursement to the Servicer or any Sub-Servicer as
provided above, shall be deposited in the Distribution Account in accordance
with Section 3.10(d)(ii) on the Servicer Remittance Date in the month following
the receipt thereof for distribution on the related Distribution Date in
accordance with Section 4.01. Any REO Disposition shall be for cash only (unless
changes in the REMIC Provisions made subsequent to the Startup Day allow a sale
for other consideration).

                  (g) The Servicer shall file information returns with respect
to the receipt of mortgage interest received in a trade or business, reports of
foreclosures and abandonments of any Mortgaged Property and cancellation of
indebtedness income with respect to any Mortgaged Property as required by
Sections 6050H, 6050J and 6050P of the Code, respectively. Such reports shall be
in form and substance sufficient to meet the reporting requirements imposed by
such Sections 6050H, 6050J and 6050P of the Code.

                  SECTION 3.24. Obligations of the Servicer in Respect of
                                Prepayment Interest Shortfalls.

                  The Servicer shall deliver to the Trustee for deposit into the
Distribution Account by 3:00 p.m. New York time on the Servicer Remittance Date
from its own funds an amount ("Compensating Interest") equal to the lesser of
(i) the aggregate of the Prepayment Interest Shortfalls for the related
Distribution Date resulting from full Principal Prepayments during the related
Prepayment Period and (ii) the aggregate Servicing Fee received in the related
Due Period. The Servicer shall not be obligated to pay Compensating Interrst
with respect to Relief Act Interest Shortfalls. Any amounts paid by the Servicer
pursuant to this Section 3.24 shall not be reimbursed by REMIC I.

                  SECTION 3.25. Obligations of the Servicer in Respect of
                                Mortgage Rates and Monthly Payments.

                  In the event that a shortfall in any collection on or
liability with respect to the Mortgage Loans in the aggregate results from or is
attributable to adjustments to Mortgage Rates, Monthly Payments or Stated
Principal Balances that were made by the Servicer in a manner not consistent
with the terms of the related Mortgage Note and this Agreement, the Servicer,
upon discovery or receipt of notice thereof, immediately shall deposit in the
Collection Account from its own funds the amount of any such shortfall and shall
indemnify and hold harmless the Trust Fund, the Trustee, the Depositor and any
successor servicer in respect of any such liability. Such indemnities shall
survive the termination or discharge of this Agreement. Notwithstanding the
foregoing, this Section 3.25 shall not limit the ability of the Servicer to seek
recovery of any such amounts from the related Mortgagor under the terms of the
related Mortgage Note, as permitted by law.

                  SECTION 3.26. Advance Facility

                  (a) Notwithstanding anything to the contrary contained herein,
(i) the Servicer is hereby authorized to enter into an advance facility
("ADVANCE FACILITY") under which (A) the Servicer sells, assigns or pledges to
another Person (together with such person's successors and assigns, an
"Advancing Person") the Servicer's rights under this Agreement to be reimbursed
for any Advances or Servicing Advances and/or (B) an Advancing Person agrees to
fund some or all Advances or Servicing Advances required to be made by the
Servicer pursuant to this Agreement and (ii) the Servicer is hereby authorized
to assign its rights to the Servicing Fee; it being understood that neither the
Trust Fund nor any party hereto shall have a right or claim (including without
limitation any right of offset) to the portion of the Servicing Fee so assigned.
No consent of the Trustee, Certificateholders or any other party is required
before the Servicer may enter into an Advance Facility. Notwithstanding the
existence of any Advance Facility under which an Advancing Person agrees to fund
Advances and/or Servicing Advances on the Servicer's behalf, the Servicer shall
remain obligated pursuant to this Agreement to make Advances and Servicing
Advances pursuant to and as required by this Agreement, and shall not be
relieved of such obligations by virtue of such Advance Facility. If the Servicer
enters into an Advance Facility, and for so long as an Advancing Person remains
entitled to receive reimbursement for any Advances including Nonrecoverable
Advances related thereto ("Advance Reimbursement Amounts") and/or Servicing
Advances, including Nonrecoverable Servicing Advances related thereto
("Servicing Advance Reimbursement Amounts" and, together with Advance
Reimbursement Amounts, "Reimbursement Amounts") (in each case to the extent that
such type of Reimbursement Amount is included in the Advance Facility), then the
Servicer shall identify such Reimbursement Amounts as received, consistently
with the reimbursement rights set forth in this Agreement, and shall remit such
Reimbursement Amounts in accordance with the documentation establishing the
Advance Facility to such Advancing Person or to a trustee, agent or custodian
(an "Advance Facility Trustee") designated by such Advancing Person.
Notwithstanding the foregoing, if so required pursuant to the terms of the
Advance Facility, the Servicer may direct the Trustee to, and if so directed the
Trustee is hereby authorized to and shall, pay to the Advancing Person or the
Advance Facility Trustee the Reimbursement Amounts identified pursuant to the
preceding sentence. Notwithstanding anything to the contrary herein, in no event
shall Reimbursement Amounts be included in Available Funds or distributed to
Certificateholders.

If the Servicer enters into an Advance Facility, the Servicer and the related
Advancing Person shall deliver to the Trustee a written notice of the existence
of such Advance Facility (an "Advance Facility Notice"), stating the identity of
the Advancing Person and any related Advance Facility Trustee. An Advance
Facility Notice may only be terminated by the joint written direction of the
Servicer and the related Advancing Person as described in Section 3.26(h) below.

(b) Reimbursement Amounts shall consist solely of amounts in respect of Advances
and/or Servicing Advances made with respect to the Mortgage Loans for which the
Servicer would be permitted to reimburse itself in accordance with this
Agreement, assuming the Servicer had made the related Advance(s) and/or
Servicing Advance(s). The Trustee shall have no duty or liability with respect
to the calculation of any Reimbursement Amount, nor shall the Trustee have any
responsibility to track or monitor the administration of the Advance Facility or
the payment of


                                       91
<PAGE>

Reimbursement Amounts to the related Advancing Person or Advance Facility
Trustee. The Servicer shall maintain and provide to any successor Servicer a
detailed accounting on a loan by loan basis as to amounts advanced by, pledged
or assigned to, and reimbursed to any Advancing Person. The successor Servicer
shall be entitled to rely on any such information provided by the predecessor
Servicer, and the successor Servicer shall not be liable for any errors in such
information.

(c) An Advancing Person who receives an assignment or pledge of the rights to be
reimbursed for Advances and/or Servicing Advances, and/or whose obligations are
limited to the making or funding of Advances will not be deemed to be a
Sub-servicer under this Agreement or be required to meet the criteria for
qualification as a Sub-servicer under this Agreement.

(d) Reimbursement Amounts allocated to reimburse Advances or Servicing Advances
made with respect to any particular Mortgage Loan shall be allocated to the
reimbursement of the unreimbursed Advances or Servicing Advances (as the case
may be) made with respect to that Mortgage Loan on a "first-in, first out"
("FIFO") basis, such that the Reimbursement Amounts shall be applied to
reimburse the Advance or Servicing Advance (as the case may be) for that
Mortgage Loan that was disbursed earliest in time first, and to reimburse the
Advance or Servicing Advance (as the case may be) for that Mortgage Loan that
was disbursed latest in time last. Liquidation Proceeds with respect to a
Mortgage Loan shall be applied to reimburse Servicing Advances outstanding with
respect to that Mortgage Loan before being applied to reimburse Advances
outstanding with respect to that Mortgage Loan. The Servicer shall provide to
the related Advancing Person or Advance Facility Trustee loan-by-loan
information with respect to each Reimbursement Amount remitted to such Advancing
Person or Advance Facility Trustee, to enable the Advancing Person or Advance
Facility Trustee to make the FIFO allocation of each such Reimbursement Amount
with respect to each Mortgage Loan.

(e) The Servicer who enters into an Advance Facility shall indemnify the
Trustee, the Trust Fund, the Depositor and any successor Servicer for any claim,
loss, liability or damage resulting from any claim by the related Advancing
Person, except to the extent that such claim, loss, liability or damage (i) in
the case of the Depositor, was incurred by reason of the Depositor's willful
misfeasance, bad faith or negligence in the performance of duties hereunder or
by reason of its reckless disregard of obligations and duties hereunder, (ii) in
the case of a successor Servicer, was incurred by reason of such successor
Servicer's willful misfeasance, bad faith or negligence in the performance of
duties hereunder or by reason of its reckless disregard of obligations and
duties hereunder or by reason of a breach of such successor Servicer's
obligations and duties under this Agreement or (iii) in the case of the Trustee
or the Trust Fund, (A) resulted from a breach of the Servicer's or a successor
Servicer's obligations and duties under this Agreement for which the Trustee is
indemnified under Section 6.03(a) or (B) was incurred by reason of willful
misfeasance, bad faith or negligence of the Trustee in the performance of its
duties hereunder or by reason of the Trustee's reckless disregard of obligations
and duties hereunder or as a result of a breach of the Trustee's obligations
under Article VIII hereof. Notwithstanding the foregoing, the exclusions set
forth in clauses (i), (ii) and (iii) above from the Servicer's obligation to
indemnify the Depositor, any successor Servicer, the Trustee and the Trust Fund
shall not be applicable, in any case, to the extent the applicable claim, loss,
liability or damage was incurred by reason of the Servicer's willful
misfeasance, bad faith or negligence in the performance of duties hereunder or
by reason of its reckless disregard of obligations and


                                       92
<PAGE>

duties hereunder or by reason of a breach of the Servicer's obligations and
duties under this Agreement.

(f) Any amendment to this Section 3.26 or to any other provision of this
Agreement that may be necessary or appropriate to effect the terms of an Advance
Facility as described generally in this Section 3.26, including amendments to
add provisions relating to a successor Servicer, may be entered into by the
Depositor, the Trustee and the Servicer without the consent of any
Certificateholder, notwithstanding anything to the contrary in this Agreement.

(g) Any rights of set-off that the Trust Fund, the Trustee, the Depositor, any
successor Servicer or any other Person might otherwise have against the Servicer
under this Agreement shall not attach to any rights to be reimbursed for
Advances or Servicing Advances that have been sold, transferred, pledged,
conveyed or assigned to any Advancing Person.

(h) At any time when an Advancing Person shall have ceased funding Advances
and/or Servicing Advances (as the case may be) and the Advancing Person or
related Advance Facility Trustee shall have received Reimbursement Amounts
sufficient in the aggregate to reimburse all Advances and/or Servicing Advances
(as the case may be) the right to reimbursement for which were assigned to the
Advancing Person, then upon the delivery of a written notice signed by the
Advancing Person and the Servicer to the Trustee terminating the Advance
Facility Notice (the "Notice of Facility Termination"), the Servicer shall again
be entitled to withdraw and retain the related Reimbursement Amounts from the
Collection Account pursuant to the applicable Sections of this Agreement.

(i) After delivery of any Advance Facility Notice, and until any such Advance
Facility Notice has been terminated by a Notice of Facility Termination, this
Section 3.26 may not be amended or otherwise modified without the prior written
consent of the related Advancing Person.

                                   ARTICLE IV

                         PAYMENTS TO CERTIFICATEHOLDERS

         Distribution Date, plus (B) any amounts in respect thereof remaining
         unpaid from previous Distribution Dates. Amounts payable as
         Uncertificated Interest in respect of REMIC I Regular Interest I-LTZZ
         shall be reduced and deferred when the REMIC I Overcollateralized
         Amount is less than the REMIC I Required Overcollateralization Amount,
         by the lesser of (x) the amount of such difference and (y) the Maximum

         Regular Interest I-LTM9 and REMIC I Regular Interest I-LTM10 in the
         same proportion as the Overcollateralization Deficiency Amount is
         allocated to the Corresponding Certificates and the Uncertificated
         Balance of REMIC I Regular Interest I-LTZZ shall be increased by such
         amount; and

                  (b) to Holders of REMIC I Regular Interest I-LT1SUB, REMIC I
         Regular Interest I-LT1GRP, REMIC I Regular Interest I-LT2SUB, REMIC I

                  (a) 98.00% of such remainder to the Holders of REMIC I Regular
         Interest I-LTAA and REMIC I Regular Interest I-LTP, until the
         Uncertificated Balance of such REMIC I Regular Interests are reduced to
         zero; provided, however, that REMIC I Regular Interest I-LTP shall not
         be reduced until the Distribution Date immediately following the
         expiration of the latest Prepayment Charge as identified on the
         Prepayment Charge Schedule or any Distribution Date thereafter, at
         which point such amount shall be distributed to REMIC I Regular
         Interest I-LTP, until $100 has been distributed pursuant to this
         clause;

                  (b) 2.00% of such remainder, first to the Holders of REMIC I

                                       94
<PAGE>

         reduced to zero and second, to the Holders of REMIC I Regular Interest
         I-LTZZ, 1.00%, until the Uncertificated Balance of such REMIC I Regular
         Interest is reduced to zero; and

                  (c) any remaining amount to the Holders of the Class R
         Certificates (in respect of the Class R-I Interest);

provided, however, that (i) 98.00% and (ii) 2.00% of any principal payments that
are attributable to an Overcollateralization Release Amount shall be allocated
to Holders of (i) REMIC I Regular Interest I-LTAA and REMIC I Regular Interest

                  On each Distribution Date, all amounts representing Prepayment
Charges in respect of the Mortgage Loans during the related Prepayment Period
and any Servicer Prepayment Charge Payment Amount paid by the Servicer during
the related Prepayment Period will be distributed by REMIC I to the Holders of

         amount equal to the remainder of the REMIC I Sub WAC Allocation
         Percentage of Available Funds for such Distribution Date after the
         distributions made pursuant to clause (i) above, allocated so that
         distributions of principal shall be deemed to be made to the REMIC I
         Regular Interests first, so as to keep the Uncertificated Balance of
         each REMIC I Regular Interest ending with the designation "GRP" equal
         to 0.01% of the aggregate Stated Principal Balance of the Mortgage
         Loans in the related Loan Group; second, to each REMIC I Regular
         Interest ending with the designation "SUB," so that the Uncertificated
         Balance of each such REMIC I Regular Interest is equal to 0.01% of the
         excess of (x) the aggregate Stated Principal Balance of the Mortgage
         Loans in the related Loan Group over (y) the Certificate Principal
         Balance of the Class A Certificate in the related Loan Group (except
         that if any such excess is a larger number than in the preceding
         distribution period, the least amount of principal shall be distributed
         to such REMIC I Regular Interests such that the REMIC I Subordinated
         Balance Ratio is maintained); and third, any remaining principal to
         REMIC I Regular Interest I-LTXX.

                  (2)(I) On each Distribution Date, the Trustee shall withdraw
from the Distribution Account that portion of Available Funds for such
Distribution Date consisting of the Group I Interest Remittance Amount for such
Distribution Date, and make the following distributions in the order of priority

         Distributable Amount and the related Unpaid Interest Shortfall Amount,
         if any, for such Certificates for such Distribution Date; and

                  (ii) concurrently, to the Holders of the Group II
         Certificates, on a PRO RATA basis, based on the entitlement of each
         such Class, an amount equal to the excess, if any, of (x) the amount
         required to be distributed pursuant to Section 4.01(a)(2)(II)(i) for
         such Distribution Date over (y) the amount actually distributed
         pursuant to such sections, from the Group II Interest Remittance
         Amount.

                  (II) On each Distribution Date the Trustee shall withdraw from
the Distribution Account that portion of Available Funds for such Distribution

Date, and make the following distributions in the order of priority described
below, in each case to the extent of the Group II Interest Remittance Amount
remaining for such Distribution Date:

                  (i) concurrently, to the Holders of the Group II Certificates,
         on a PRO RATA basis based on the entitlement of each such Class, the
         related Monthly Interest Distributable Amount and the related Unpaid
         Interest Shortfall Amount, if any, for such Certificates for such
         Distribution Date; and

                  (ii) concurrently, to the Holders of the Group I Certificates,
         on a PRO RATA basis, based on the entitlement of each such Class, an
         amount equal to the excess, if any, of (x) the amount required to be
         distributed pursuant to Section 4.01(a)(2)(I)(i) for such Distribution
         Date over (y) the amount actually distributed pursuant to such sections
         from the Group I Interest Remittance Amount. (III) On each Distribution
         Date, following the distributions made pursuant to Section
         4.01(a)(2)(I) and Section 4.01(a)(2)(II) above, the Trustee shall make
         the following distributions in the order of priority described below,
         in each case to the extent of the sum of the Group I Interest
         Remittance Amount and the Group II Interest Remittance Amount remaining

                  (iii) to the Holders of the Class M-1 Certificates, the

         distributed in the following order of priority:

                  (i) to the Class A Certificates, on a PRO RATA basis based on

amounts then on deposit in the Distribution Account that represent (i)
Prepayment Charges collected by the Servicer in connection with the Principal
Prepayment of any of the Mortgage Loans or (ii) any Servicer Prepayment Charge
Payment Amount, and shall distribute such amounts to the Holders of the Class P
Certificates. Such distributions shall not be applied to reduce the Certificate
Principal Balance of the Class P Certificates.

                  Following the foregoing distributions, an amount equal to the
amount of Subsequent Recoveries remitted to the Servicer shall be applied to
increase the Certificate Principal Balance of the Class of Certificates with the
Highest Priority up to the extent of such Realized Losses previously allocated
to that Class of Certificates pursuant to Section 4.04. An amount equal to the
amount of any remaining Subsequent Recoveries shall be applied to increase the
Certificate Principal Balance of the Class of Certificates with the next Highest
Priority, up to the amount of such Realized Losses previously allocated to that
Class of Certificates pursuant to Section 4.04. Holders of such Certificates
will not be entitled to any distribution in respect of interest on the amount of
such increases for any Accrual Period preceding the Distribution Date on which
such increase occurs. Any such increases shall be applied to the Certificate
Principal Balance of each Certificate of such Class in accordance with its
respective Percentage Interest.

                  (b) All distributions made with respect to each Class of
Certificates on each Distribution Date shall be allocated PRO RATA among the

on the related Record Date (except as otherwise provided in Section 4.01(e) or
Section 9.01 respecting the final distribution on such Class), based on the
aggregate Percentage Interest represented by their respective Certificates, and
shall be made by wire transfer of immediately


                                      103

available funds to the account of any such Holder at a bank or other entity
having appropriate facilities therefor, if such Holder shall have so notified
the Trustee in writing at least five Business Days prior to the Record Date
immediately prior to such Distribution Date and is the registered owner of
Certificates having an initial aggregate Certificate Principal Balance or
Notional Amount that is in excess of the lesser of (i) $5,000,000 or (ii)
two-thirds of the initial Certificate Principal Balance or Notional Amount of
such Class of Certificates, or otherwise by check mailed by first class mail to
the address of such Holder appearing in the Certificate Register. The final
distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the Corporate Trust Office of
the Trustee or such other location specified in the notice to Certificateholders
of such final distribution.

                  Each distribution with respect to a Book-Entry Certificate
shall be paid to the Depository, as Holder thereof, and the Depository shall be
responsible for crediting the amount of such distribution to the accounts of its
Depository Participants in accordance with its normal procedures. Each
Depository Participant shall be responsible for disbursing such distribution to
the Certificate Owners that it represents and to each indirect participating
brokerage firm (a "brokerage firm" or "indirect participating firm") for which
it acts as agent. Each brokerage firm shall be responsible for disbursing funds
to the Certificate Owners that it represents. None of the Trustee, the Depositor
or the Servicer shall have any responsibility therefor except as otherwise
provided by this Agreement or applicable law.

                  (c) The rights of the Certificateholders to receive
distributions in respect of the Certificates, and all interests of the
Certificateholders in such distributions, shall be as set forth in this
Agreement. None of the Holders of any Class of Certificates, the Trustee or the
Servicer shall in any way be responsible or liable to the Holders of any other
Class of Certificates in respect of amounts properly previously distributed on
the Certificates.

                  (d) Except as otherwise provided in Section 9.01, whenever the
Trustee expects that the final distribution with respect to any Class of
Certificates will be made on the next Distribution Date, the Trustee shall, no
later than three (3) days before the related Distribution Date, mail to each
Holder on such date of such Class of Certificates a notice to the effect that:

                  (i)      the Trustee expects that the final distribution with
                           respect to such Class of Certificates will be made on
                           such Distribution Date but only upon presentation and
                           surrender of such Certificates at the office of the
                           Trustee therein specified, and

                  (B)      no interest shall accrue on such Certificates from
                           and after the end of the related Accrual Period.

                  Any funds not distributed to any Holder or Holders of
Certificates of such Class 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 by the Trustee 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 4.01(e) shall not have been
surrendered for cancellation within six months after the time specified in such
notice, the Trustee shall mail a


                                      104
<PAGE>

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 Trustee
shall, directly or through an agent, mail a final notice to the remaining
non-tendering Certificateholders concerning surrender of their Certificates but
shall continue to hold any remaining funds for the benefit of non-tendering
Certificateholders. 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 Fund. If within one year after the final notice any such
Certificates shall not have been surrendered for cancellation, the Trustee shall
pay to UBS Securities LLC 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 Trustee as a result of such Certificateholder's failure to surrender its
Certificate(s) for final payment thereof in accordance with this Section
4.01(e). Any such amounts held in trust by the Trustee shall be held in an
Eligible Account and the Trustee may direct any depository institution
maintaining such account to invest the funds in one or more Permitted
Investments. All income and gain realized from the investment of funds deposited
in such accounts held in trust by the Trustee shall be for the benefit of the
Trustee; provided, however, that the Trustee shall deposit in such account the
amount of any loss of principal incurred in respect of any such Permitted
Investment made with funds in such accounts immediately upon the realization of
such loss.

                  (e) Notwithstanding anything to the contrary herein, (i) in no
event shall the Certificate Principal Balance of a Class A Certificate or a
Mezzanine Certificate be reduced more than once in respect of any particular
amount both (a) allocated to such Certificate in respect of Realized Losses
pursuant to Section 4.04 and (b) distributed to the Holder of such Certificate
in reduction of the Certificate Principal Balance thereof pursuant to this
Section 4.01 from Net Monthly Excess Cashflow and (ii) in no event shall the
Uncertificated Balance of a REMIC I Regular Interest be reduced more than once
in respect of any particular amount both (a) allocated to such REMIC I Regular
Interest in respect of Realized Losses pursuant to Section 4.04 and (b)
distributed on such REMIC I Regular Interest in reduction of the Uncertificated
Balance thereof pursuant to this Section 4.01.

                  SECTION 4.03. Remittance Reports; Advances.

                  (a) Not later than the eighteenth day of each calendar month
or if such eighteenth day is not a Business Day, the following Business Day, the
Servicer shall deliver to the Trustee, the Credit Risk Manager and the NIMS
Insurer by telecopy or electronic mail (or by such other means as the Servicer
and the Trustee may agree from time to time) a Remittance Report with respect to
the related Distribution Date. Not later than the eighteenth day of each
calendar month or if such eighteenth day is not a Business Day, the following
Business Day, the Servicer shall deliver or cause to be delivered to the Trustee
in addition to the information provided on the Remittance Report, such other
information reasonably available to it with respect to the Mortgage Loans as the
Trustee may reasonably require to perform the calculations necessary to make the
distributions contemplated by Section 4.01 and to prepare the statements to
Certificateholders contemplated by Section 4.03. The Trustee shall not be
responsible to recompute, recalculate or verify any information provided to it
by the Servicer.

                  (b) The amount of Advances to be made by the Servicer for any
Distribution Date shall equal, subject to Section 4.03(d), the sum of (i) the
aggregate amount of Monthly Payments (net of the related Servicing Fee), due
during the related Due Period in respect of the Mortgage Loans, which Monthly
Payments were delinquent on a contractual basis as of the close of business on
the related Determination Date; and (ii) with respect to each REO Property,
which REO Property was acquired during or prior to the related Due Period and as
to which REO Property an REO Disposition did not occur during the related Due
Period, an amount equal to the


                                      108
<PAGE>

excess, if any, of the REO Imputed Interest on such REO Property for the most
recently ended calendar month, over the net income from such REO Property
transferred to the Distribution Account pursuant to Section 3.23 for
distribution on such Distribution Date.

                  On or before 3:00 p.m. New York time on the Servicer
Remittance Date, the Servicer shall remit in immediately available funds to the
Trustee for deposit in the Distribution Account an amount equal to the aggregate
amount of Advances, if any, to be made in respect of the Mortgage Loans and REO
Properties for the related Distribution Date either (i) from its own funds or
(ii) from the Collection Account, to the extent of funds held therein for future
distribution (in which case it will cause to be made an appropriate entry in the
records of Collection Account that amounts held for future distribution have
been, as permitted by this Section 4.03, used by the Servicer in discharge of
any such Advance) or (iii) in the form of any combination of (i) and (ii)
aggregating the total amount of Advances to be made by the Servicer with respect
to the Mortgage Loans and REO Properties. Any amounts held for future
distribution used by the Servicer to make an Advance as permitted in the
preceding sentence shall be appropriately reflected in the Servicer's records
and replaced by the Servicer by deposit in the Collection Account on or before
any future Servicer Remittance Date to the extent that the Available Funds for
the related Distribution Date (determined without regard to Advances to be made
on the Servicer Remittance Date) shall be less than the total amount that would
be distributed to the Classes of Certificateholders pursuant to Section 4.01 on
such Distribution Date if such amounts held for future distributions had not
been so used to make Advances. The Trustee will provide notice to the Servicer
and the NIMS Insurer by telecopy by the close of business on any Servicer
Remittance Date in the event that the amount remitted by the Servicer to the
Trustee on such date is less than the Advances required to be made by the
Servicer for the related Distribution Date, as set forth in the related
Remittance Report.

                  (c) The obligation of the Servicer to make such Advances is
mandatory, notwithstanding any other provision of this Agreement but subject to
(d) below and, with respect to any Mortgage Loan, shall continue until the
Mortgage Loan is paid in full or until all Liquidation Proceeds thereon have
been recovered, or a Final Recovery Determination has been made thereon.

                  (d) Notwithstanding anything herein to the contrary, no
Advance or Servicing Advance shall be required to be made hereunder by the
Servicer if such Advance or Servicing Advance would, if made, constitute a
Nonrecoverable Advance or Nonrecoverable Servicing Advance, respectively. The
determination by the Servicer that it has made a Nonrecoverable Advance or a
Nonrecoverable Servicing Advance or that any proposed Advance or Servicing
Advance, if made, would constitute a Nonrecoverable Advance or Nonrecoverable
Servicing Advance, respectively, shall be evidenced by an Officers' Certificate
of the Servicer delivered to the Depositor, the NIMS Insurer, the Credit Risk
Manager and the Trustee. Furthermore, the Servicer shall not be required to
advance Relief Act Interest Shortfalls.

                  SECTION 4.04. Allocation of Realized Losses.

                  (a) Not later than the eighteenth day of the calendar month in
which such Distribution Date occurs or if such eighteenth day is not a Business
Day, the following Business Day, the Servicer shall determine as to each
Mortgage Loan and REO Property: (i) the total


                                      109
<PAGE>

amount of Realized Losses, if any, incurred in connection with any Final
Recovery Determinations made during the related Prepayment Period; and (ii) the
respective portions of such Realized Losses allocable to interest and allocable
to principal. Not later than the eighteenth day of the calendar month in which
such Distribution Date occurs or if such eighteenth day is not a Business Day,
the following Business Day, the Servicer shall also determine as to each
Mortgage Loan: (i) the total amount of Realized Losses, if any, incurred in
connection with any Deficient Valuations made during the related Prepayment
Period; and (ii) the total amount of Realized Losses, if any, incurred in
connection with Debt Service Reductions in respect of Monthly Payments due
during the related Due Period. The information described in the preceding
sentence that is to be supplied by the Servicer shall be evidenced by an
Officer's Certificate delivered to the Trustee by the Servicer not later than
the eighteenth day of the calendar month in which such Distribution Date occurs
or if such eighteenth day is not a Business Day, the following Business Day,
immediately following the end of the Prepayment Period during which any such
Realized Loss was incurred.

                  (b) All Realized Losses on the Mortgage Loans shall be
allocated by the Trustee on each Distribution Date as follows: first, to Net
Monthly Excess Cashflow; second, to the Class CE Certificates, until the
Certificate Principal Balance thereof has been reduced to zero; third to the
Class M-10 Certificates, until the Certificate Principal Balance thereof has
been reduced to zero; fourth, to the Class M-9 Certificates, until the
Certificate Principal Balance thereof has been reduced to zero; fifth, to the
Class M-8 Certificates, until the Certificate Principal Balance thereof has been
reduced to zero; sixth, to the Class M-7 Certificates, until the Certificate
Principal Balance thereof has been reduced to zero; seventh, to the Class M-6
Certificates, until the Certificate Principal Balance thereof has been reduced
to zero; eighth, to the Class M-5 Certificates, until the Certificate Principal

has been reduced to zero; eleventh, to the Class M-2 Certificates, until the
Certificate Principal Balance thereof has been reduced to zero; and twelfth, to
the Class M-1 Certificates, until the Certificate Principal Balance thereof has
been reduced to zero. All Realized Losses to be allocated to the Certificate
Principal Balances of all Classes on any Distribution Date shall be so allocated
after the actual distributions to be made on such date as provided above. All
references above to the Certificate Principal Balance of any Class of
Certificates shall be to the Certificate Principal Balance of such Class
immediately prior to the relevant Distribution Date, before reduction thereof by
any Realized Losses, in each case to be allocated to such Class of Certificates,
on such Distribution Date.

                  Any allocation of Realized Losses to a Mezzanine Certificate
on any Distribution Date shall be made by reducing the Certificate Principal
Balance thereof by the amount so allocated; any allocation of Realized Losses to
a Class CE Certificate shall be made by reducing the amount otherwise payable in
respect thereof pursuant to Section 4.01(a)(4)(xviii). No allocations of any
Realized Losses shall be made to the Certificate Principal Balances of the Class
A Certificates or the Class P Certificates.

                  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


                                      110
<PAGE>

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.

                  (c) (i) The REMIC I Marker Percentage of all Realized Losses
on the Mortgage Loans shall be allocated by the Trustee on each Distribution
Date to the following REMIC I Regular Interests in the specified percentages, as

Interest I-LTAA and REMIC I Regular Interest I-LTZZ up to an aggregate amount
equal to the REMIC I Interest Loss Allocation Amount, 98% and 2%, respectively;

Regular Interest I-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated
Balance of REMIC I Regular Interest I-LTM9 has been reduced to zero; fifth, to

Interest I-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance
of REMIC I Regular Interest I-LTM7 has been reduced to zero; seventh to the
Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular
Interest I-LTM6 and REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Balance of REMIC I Regular Interest
I-LTM6 has been reduced to zero; eighth, to the Uncertificated Balances of REMIC
I Regular Interest I-LTAA, REMIC I Regular Interest I-LTM5 and REMIC I Regular
Interest II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance
of REMIC I Regular Interest I-LTM5 has been reduced to zero; ninth, to the
Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular
Interest I-LTM4 and REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Balance of REMIC I Regular Interest
I-LTM4 has been reduced to zero; tenth, to the Uncertificated Balances of REMIC
I Regular Interest I-LTAA, REMIC I Regular Interest I-LTM3 and REMIC I Regular
Interest I-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance
of REMIC I Regular Interest I-LTM3 has been reduced to zero; eleventh, to the
Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular
Interest I-LTM2 and REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%,

I-LTM2 has been reduced to zero; and twelfth, to the Uncertificated Balances of
REMIC I Regular Interest I-LTAA, REMIC I Regular Interest I-LTM1 and REMIC I
Regular Interest I-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated
Balance of REMIC I Regular Interest I-LTM1 has been reduced to zero.

                  (ii) The REMIC I Sub WAC Allocation Percentage of all Realized
Losses shall be applied after all distributions have been made on each
Distribution Date first, so as to keep the Uncertificated Balance of each REMIC
I Regular Interest ending with the designation


                                      111
<PAGE>

"GRP" equal to 0.01% of the aggregate Stated Principal Balance of the Mortgage
Loans in the related Loan Group; second, to each REMIC I Regular Interest ending
with the designation "SUB," so that the Uncertificated Balance of each such
REMIC I Regular Interest is equal to 0.01% of the excess of (x) the aggregate
Stated Principal Balance of the Mortgage Loans in the related Loan Group over
(y) the Certificate Principal Balance of the Class A Certificate in the related
Loan Group (except that if any such excess is a larger number than in the
preceding distribution period, the least amount of Realized Losses shall be
applied to such REMIC I Regular Interests such that the REMIC I Subordinated
Balance Ratio is maintained); and third, any remaining Realized Losses shall be
allocated to REMIC I Regular Interest I-LTXX.

                  SECTION 4.05. Compliance with Withholding Requirements

                  Notwithstanding any other provision of this Agreement, the
Trustee shall comply with all federal withholding requirements respecting

Trustee reasonably believes are applicable under the Code. The consent of
Certificateholders shall not be required for such withholding. In the event the
Trustee does withhold any amount from interest or original issue discount
payments or advances thereof to any Certificateholder pursuant to federal
withholding requirements, the Trustee shall indicate the amount withheld to such
Certificateholders.

                  SECTION 4.06. Exchange Commission; Additional Information.

                  (a) The Trustee and the Servicer shall reasonably cooperate

Trust Fund. To the extent that the Commission requires any additional

                  (b) Each Form 8-K shall be filed by the Trustee within 15 days

as required by applicable law or applicable Commission staff's interpretations.
Such Form 10-K shall include as exhibits the Servicer's annual statement of

Trustee shall have no liability with respect to any failure to properly prepare
or file such periodic reports resulting from or relating to (a) the Trustee's
inability or failure to obtain any information not resulting from its own
negligence or willful misconduct or (b) any inaccuracy in such periodic reports
resulting from incorrect information provided to the Trustee by the Servicer in
a Remittance Report or otherwise. The Form 10-K shall also include a
certification in the form attached hereto as Exhibit J-1 (the "Certification"),
which shall be signed by the Trustee.

                  (c) In addition, the Servicer shall sign a certification (in

Certification (provided, however, that the Servicer shall not undertake an
analysis of the accountant's report attached as an exhibit to the Form 10-K).
The Servicer's certification shall be delivered to the Trustee by no later than
March 15th of each year (or if such day is not a Business Day, the immediately
preceding Business Day).

                  In addition, (i) the Trustee shall, subject to the provisions
of Sections 8.01 and 8.02, indemnify and hold harmless the Depositor and the
Servicer and their respective officers, directors and Affiliates from and
against any losses, damages, penalties, fines, forfeitures, reasonable and

connection therewith, and (ii) the 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 Servicer's obligations
under this Section 4.06(b) or the Servicer's negligence, bad faith or willful
misconduct in connection therewith. If the indemnification provided for herein
is unavailable or insufficient to hold harmless the Depositor or the Servicer,
then (i) the Trustee agrees that it shall contribute to the amount paid or
payable by the Depositor or the Servicer, as applicable, as a result of the
losses, claims, damages or liabilities of the Depositor or the Servicer, as
applicable, in such proportion as is appropriate to reflect the relative fault
of the or the Depositor or the Servicer, as applicable, on the one hand and the
Trustee on the other in connection with a breach of the Trustee's obligations
under this Section 4.06(b) or the Trustee's negligence, bad faith or willful

bad faith or willful misconduct in connection therewith. Notwithstanding any
other provision in this Agreement to the contrary, the Servicer shall not have
any responsibility or liability to any party relating to the certification or
information prepared, certified or distributed by the Trustee or any other party
other than the Servicer unless such information was derived from erroneous or
incomplete information required to be provided by the Servicer under this
Agreement.

Asset Backed Securities Trust 2005-NC1, Mortgage Pass-Through Certificates,
Series 2005-NC1--Net WAC Rate Carryover Reserve Account." All amounts deposited
in the Net WAC Rate Carryover Reserve Account shall be distributed to the
Holders of the Class A and/or the Mezzanine Certificates in the manner set forth
in Section 4.01(d).

                  On each Distribution Date as to which there is a Net WAC Rate
Carryover Amount payable to the Class A and/or the Mezzanine Certificates, the
Trustee has been directed by the Class CE Certificateholders to, and therefore
will, deposit into the Net WAC Rate Carryover Reserve Account the amounts
described in Section 4.01(a)(4)(xvii), rather than distributing such amounts to
the Class CE Certificateholders. In addition, any payments received by the
Trustee under the Cap Contracts on each Distribution Date will be deposited into
the Net WAC Rate Carryover Reserve Account. On each such Distribution Date, the
Trustee shall hold all such amounts for the benefit of the Holders of the Class
A and the Mezzanine Certificates, and will distribute such amounts to the
Holders of the Class A and the Mezzanine Certificates, as applicable, in the
amounts and priorities set forth in Section 4.01(d).

                  On each Distribution Date, any amounts remaining in the Net
WAC Rate Carryover Reserve Account (representing payments received by the
Trustee under the Cap Contracts) after the payment of any Net WAC Rate Carryover
Amounts on the Class A and the Mezzanine Certificates, as applicable, for such
Distribution Date, shall be payable to the Trustee.

                  For federal and state income tax purposes, the Trustee will be
deemed to be the owner of the Net WAC Rate Carryover Reserve Account (other than
amounts paid by the Cap Contracts). All amounts deposited into the Net WAC Rate
Carryover Reserve Account (other than amounts received under the Cap Contracts)
shall be treated as amounts distributed by REMIC II to the Holder of the Class
CE Interest and by REMIC III to the Holder of the Class CE Certificates. The Net
WAC Rate Carryover Reserve Account will be an "outside reserve fund" within the
meaning of Treasury Regulation Section 1.860G-2(h). Upon the termination of the
Trust, or the payment in full of the Class A and the Mezzanine Certificates, all
amounts remaining on deposit in the Net WAC Rate Carryover Reserve Account will
be released by the Trust and distributed to the Trustee or its designee. The Net
WAC Rate Carryover Reserve Account will be part of the Trust but not part of any
REMIC and any payments to the Holders of the Class A and the Mezzanine
Certificates of Net WAC Rate Carryover Amounts will not be


                                      114
<PAGE>

payments with respect to a "regular interest" in a REMIC within the meaning of
Code Section 860(G)(a)(1).

                  By accepting a Class CE Certificate, each Class CE
Certificateholder hereby agrees to direct the Trustee, and the Trustee hereby is
directed, to deposit into the Net WAC Rate Carryover Reserve Account the amounts
described above on each Distribution Date as to which there is any Net WAC Rate
Carryover Amount rather than distributing such amounts to the Class CE
Certificateholders. By accepting a Class CE Certificate, each Class CE
Certificateholder further agrees that such direction is given for good and
valuable consideration, the receipt and sufficiency of which is acknowledged by
such acceptance.

                  Amounts on deposit in the Net WAC Rate Carryover Reserve
Account shall remain uninvested.

                  For federal tax return and information reporting, the purchase
price allocated to each applicable Cap Contract in respect of any Net WAC Rate
Carryover Amount may be obtained from the Trustee, upon receipt from the
Depositor.

                                THE CERTIFICATES

                  SECTION 5.01. The Certificates.

                  (a) The Certificates in the aggregate will represent the
entire beneficial ownership interest in the Mortgage Loans and all other assets
included in REMIC I.

                  The Certificates will be substantially in the forms annexed
hereto as Exhibits A-1 through A-20. The Certificates of each Class will be
issuable in registered form only, in denominations of authorized Percentage
Interests as described in the definition thereof. Each Certificate will share
ratably in all rights of the related Class.

                  Upon original issue, the Certificates shall be executed by the
Trustee and authenticated and delivered by the Trustee to or upon the order of
the Depositor. The Certificates shall be executed by manual or facsimile
signature on behalf of the Trustee by an authorized signatory. Certificates
bearing the manual or facsimile signatures of individuals who were at any time
the proper officers of the Trustee shall bind the Trustee notwithstanding that
such individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of such Certificates or did not hold such offices at
the date of such Certificates. No Certificate shall be entitled to any benefit
under this Agreement or be valid for any purpose, unless there appears on such
Certificate a certificate of authentication substantially in the form provided
herein executed by the Trustee by manual signature, and such certificate of
authentication 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.

                  (b) The Class A Certificates and the Mezzanine Certificates
shall initially be issued as one or more Certificates held by the Book-Entry
Custodian or, if appointed to hold such Certificates as provided below, the
Depository and registered in the name of the Depository or its nominee and,
except as provided below, registration of such Certificates may not be
transferred by the Trustee except to another Depository that agrees to hold such
Certificates for the respective Certificate Owners with Ownership Interests
therein. The Certificate Owners shall hold their respective Ownership Interests
in and to such Certificates through the book-entry facilities of the Depository
and, except as provided below, shall not be entitled to definitive, fully
registered Certificates ("Definitive Certificates") in respect of such Ownership
Interests. All transfers by Certificate Owners of their respective Ownership
Interests in the Book-Entry Certificates shall be made in accordance with the
procedures established by the Depository Participant or brokerage firm
representing such Certificate Owner. Each Depository Participant shall only
transfer the Ownership Interests in the Book-Entry Certificates of Certificate
Owners it represents or of brokerage firms for which it acts as agent in
accordance with the Depository's normal procedures. The Trustee is hereby
initially appointed as the Book-Entry Custodian and hereby agrees to act as such
in accordance herewith and in accordance with the agreement that it has with the
Depository authorizing it to act as such. The Book-Entry Custodian may, and, if
it is no longer qualified to act as such, the Book-Entry Custodian shall,
appoint, by a written instrument delivered to the Depositor, the Servicer and
the Trustee, any other transfer agent


                                      116
<PAGE>

(including the Depository or any successor Depository) to act as Book-Entry
Custodian under such conditions as the predecessor Book-Entry Custodian and the
Depository or any successor Depository may prescribe, provided that the
predecessor Book-Entry Custodian shall not be relieved of any of its duties or
responsibilities by reason of any such appointment of other than the Depository.
If the Trustee resigns or is removed in accordance with the terms hereof, the
successor trustee or, if it so elects, the Depository shall immediately succeed
to its predecessor's duties as Book-Entry Custodian. The Depositor shall have
the right to inspect, and to obtain copies of, any Certificates held as
Book-Entry Certificates by the Book-Entry Custodian.

                  The Trustee, the Servicer and the Depositor may for all
purposes (including the making of payments due on the Book-Entry Certificates)
deal with the Depository as the authorized representative of the Certificate
Owners with respect to the Book-Entry Certificates for the purposes of
exercising the rights of Certificateholders hereunder. The rights of Certificate
Owners with respect to the Book-Entry Certificates shall be limited to those
established by law and agreements between such Certificate Owners and the
Depository Participants and brokerage firms representing such Certificate
Owners. Multiple requests and directions from, and votes of, the Depository as
Holder of the Book-Entry Certificates with respect to any particular matter
shall not be deemed inconsistent if they are made with respect to different
Certificate Owners. The Trustee may establish a reasonable record date in
connection with solicitations of consents from or voting by Certificateholders
and shall give notice to the Depository of such record date.

                  If (i)(A) the Depositor advises the Trustee in writing that
the Depository is no longer willing or able to properly discharge its
responsibilities as Depository, and (B) the Depositor is unable to locate a
qualified successor or (ii) after the occurrence of a Servicer Event of Default,
Certificate Owners representing in the aggregate not less than 51% of the
Ownership Interests of the Book-Entry Certificates advise the Trustee through
the Depository, 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
Trustee shall notify all Certificate Owners, through the Depository, of the
occurrence of any such event and of the availability of Definitive Certificates
to Certificate Owners requesting the same. Upon surrender to the Trustee of the
Book-Entry Certificates by the Book-Entry Custodian or the Depository, as
applicable, accompanied by registration instructions from the Depository for
registration of transfer, the Trustee shall cause the Definitive Certificates to
be issued. Such Definitive Certificates will be issued in minimum denominations
of $25,000, except that any beneficial ownership that was represented by a
Book-Entry Certificate in an amount less than $25,000 immediately prior to the
issuance of a Definitive Certificate shall be issued in a minimum denomination
equal to the amount represented by such Book-Entry Certificate. None of the
Depositor, the Servicer or the Trustee shall be liable for any delay in the
delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions. Upon the issuance of Definitive
Certificates all references herein to obligations imposed upon or to be
performed by the Depository shall be deemed to be imposed upon and performed by
the Trustee, to the extent applicable with respect to such Definitive
Certificates, and the Trustee shall recognize the Holders of the Definitive
Certificates as Certificateholders hereunder.

                  SECTION 5.02. Registration of Transfer and Exchange of
                                Certificates.

                  (a) The Trustee shall cause to be kept at one of the offices
or agencies to be appointed by the Trustee in accordance with the provisions of
Section 8.11, a Certificate Register for the Certificates in which, subject to
such reasonable regulations as it may prescribe, the Trustee shall provide for
the registration of Certificates and of transfers and exchanges of Certificates
as herein provided.

No transfer of any Class CE Certificate, Class P Certificate or Residual
Certificate (the "Private Certificates") shall be made unless that transfer is
made pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "1933 Act"), and 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 a Certificate is to be made without registration or qualification
(other than in connection with (i) the initial transfer of any Private
Certificate by the Depositor to an Affiliate of the Depositor, (ii) the transfer
of any Private Certificate to the issuer under the Indenture or the indenture
trustee under the Indenture or (iii) a transfer of any Private Certificate from
the issuer under the Indenture or the indenture trustee under the Indenture to
the Depositor or an Affiliate of the Depositor)

                  (b)        , the Trustee 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 Certificateholder desiring to effect the
transfer and from such Certificateholder's prospective transferee, substantially
in the forms attached hereto as Exhibit F-1; 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 Servicer in its
capacity as such or any Sub-Servicer), together with copies of the written
certification(s) of the Certificateholder desiring to effect the transfer and/or
such Certificateholder's prospective transferee upon which such Opinion of
Counsel is based, if any. None of the Depositor, the Servicer or the Trustee is
obligated to register or qualify any such Certificates under the 1933 Act or any
other securities laws or to take any action not otherwise required under this
Agreement to permit the transfer of such Certificates without registration or
qualification. Any Certificateholder desiring to effect the transfer of any such
Certificate shall, and does hereby agree to, indemnify the Trustee, the
Depositor and the 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 a Private Certificate or any interest therein shall be made to
any 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 such transferee in the form of
Exhibit G, unless the Trustee is provided with an Opinion of Counsel for the
benefit of the Trustee, the Depositor and the Servicer and on which they may
rely which establishes to the satisfaction of the Depositor, the Trustee and the
Servicer 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 Servicer, the
NIMS Insurer, the Trustee or the Trust Fund to any obligation or liability
(including obligations or liabilities under ERISA or Section 4975 of the Code)
in


                                      118
<PAGE>

addition to those undertaken in this Agreement, which Opinion of Counsel shall
not be an expense of the Depositor, the Servicer, the Trustee or the Trust Fund.
Neither an Opinion of Counsel nor any certification will be required in
connection with the (i) the initial transfer of any Private Certificate by the
Depositor to an Affiliate of the Depositor, (ii) the transfer of any Private
Certificate to the issuer under the Indenture or the indenture trustee under the
Indenture or (iii) a transfer of any Private Certificate from the issuer under
the Indenture or the indenture trustee under the Indenture to the Depositor or
an Affiliate of the Depositor (in which case, the Transferee thereof shall have
deemed to have represented that it is not a Plan or a Person investing Plan
Assets) and the Trustee shall be entitled to conclusively rely upon a
representation (which, upon the request of the Trustee, shall be a written
representation) from the Transferor of the status of such transferee as an
affiliate of the Depositor.


                  Each beneficial owner of a Mezzanine Certificates or any
interest therein shall be deemed to have represented, by virtue of its
acquisition or holding of that certificate or interest therein, that either (i)
it is not a Plan investor, (ii) it has acquired and is holding such Mezzanine
Certificates in reliance on the Underwriters' Exemption, and that it understands
that there are certain conditions to the availability of the Underwriters'
Exemption, including that the Mezzanine Certificates must be rated, at the time
of purchase, not lower than "BBB-" (or its equivalent) by Moody's, S&P or Fitch
(iii) (1) it is an insurance company, (2) the source of funds used to acquire or
hold the certificate or interest therein is an "insurance company general
account," as such term is defined in PTCE 95-60, and (3) the conditions in
Sections I and III of PTCE 95-60 have been satisfied.

                  If any Mezzanine Certificate or Private Certificate or any
interest therein is acquired or held in violation of the provisions of the
preceding two paragraphs, 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 effected
in violation of the provisions of the preceding two paragraphs shall indemnify
and hold harmless the Depositor, the Servicer, the NIMS Insurer, the Trustee and
the Trust Fund from and against any and all liabilities, claims, costs or
expenses incurred by those parties as a result of that acquisition or holding.

                  (c) (i) Each Person who has or who acquires any Ownership
Interest in a Residual Certificate shall be deemed by the acceptance or
acquisition of such Ownership Interest to have agreed to be bound by the
following provisions and to have irrevocably authorized the Trustee or its
designee under clause (iii)(A) below to deliver payments to a Person other than
such Person and to negotiate the terms of any mandatory sale under clause
(iii)(B) below and to execute all instruments of Transfer and to do all other
things necessary in connection with any such sale. The rights of each Person
acquiring any Ownership Interest in a Residual Certificate are expressly subject
to the following provisions:

                  (A)      Each Person holding or acquiring any Ownership
                           Interest in a Residual Certificate shall be a
                           Permitted Transferee and shall promptly notify the
                           Trustee of any change or impending change in its
                           status as a Permitted Transferee.

                  (B)      In connection with any proposed Transfer of any
                           Ownership Interest in a Residual Certificate, the
                           Trustee shall require delivery to it, and shall not
                           register the Transfer of any Residual Certificate
                           until its receipt of, an affidavit and agreement (a
                           "Transfer Affidavit and Agreement," in the form
                           attached hereto as Exhibit F-2) from the proposed
                           Transferee, in form and substance satisfactory to the
                           Trustee, representing and warranting, among other
                           things, that such Transferee is a Permitted
                           Transferee, that it is not acquiring its Ownership
                           Interest in the Residual Certificate that is the
                           subject of the proposed Transfer as a nominee,
                           trustee or agent for any Person that is not a
                           Permitted Transferee, that for so long as it retains
                           its Ownership Interest in a Residual Certificate, it
                           will endeavor to remain a Permitted Transferee, and
                           that it has reviewed the provisions of this Section
                           5.02(d) and agrees to be bound by them.

                  (C)      Notwithstanding the delivery of a Transfer Affidavit
                           and Agreement by a proposed Transferee under clause
                           (B) above, if a Responsible Officer of the Trustee
                           who is assigned to this transaction has actual
                           knowledge that the proposed Transferee is not a
                           Permitted Transferee, no Transfer of an Ownership
                           Interest in a Residual Certificate to such proposed
                           Transferee shall be effected.

                  (D)      Each Person holding or acquiring any Ownership
                           Interest in a Residual Certificate shall agree (x) to
                           require a Transfer Affidavit and Agreement in the
                           form attached hereto as Exhibit F-2 from any other
                           Person to whom such Person attempts to transfer its
                           Ownership Interest in a Residual Certificate and (y)
                           not to transfer its Ownership Interest unless it
                           provides a Transferor Affidavit (in the form attached
                           hereto as Exhibit F-2) to the Trustee stating that,
                           among other things, it has no actual knowledge that
                           such other Person is not a Permitted Transferee.

                  (E)      Each Person holding or acquiring an Ownership
                           Interest in a Residual Certificate, by purchasing an
                           Ownership Interest in such Certificate, agrees to
                           give the Trustee written notice that it is a
                           "pass-through interest holder" within the meaning of
                           temporary Treasury regulation Section
                           1.67-3T(a)(2)(i)(A) immediately upon acquiring an
                           Ownership Interest in a Residual Certificate, if it
                           is, or is holding an Ownership Interest in a Residual
                           Certificate on behalf of, a "pass-through interest
                           holder."

                  (ii) The Trustee will register the Transfer of any Residual
         Certificate only if it shall have received the Transfer Affidavit and
         Agreement and all of such other documents as shall have been reasonably
         required by the Trustee as a condition to such registration. In
         addition, no Transfer of a Residual Certificate shall be made unless
         the Trustee shall have received a representation letter from the
         Transferee of such Certificate to the effect that such Transferee is a
         Permitted Transferee.

                  (iii)(A) If any purported Transferee shall become a Holder of
         a Residual Certificate in violation of the provisions of this Section
         5.02(d), then the last preceding Permitted Transferee shall be
         restored, to the extent permitted by law, to all rights as holder
         thereof retroactive to the date of registration of such Transfer of
         such Residual Certificate. The Trustee shall be under no liability to
         any Person for any registration of Transfer of a Residual Certificate
         that is in fact not permitted by this Section 5.02(d) or for making any
         payments due on such Certificate to the holder thereof or for taking
         any other action with respect to such holder under the provisions of
         this Agreement.

                  (B) If any purported Transferee shall become a holder of a
         Residual Certificate in violation of the restrictions in this Section
         5.02(d) and to the extent that the retroactive restoration of the
         rights of the holder of such Residual Certificate as described in
         clause (iii)(A) above shall be invalid, illegal or unenforceable, then
         the Trustee shall have the right, without notice to the holder or any
         prior holder of such Residual Certificate, to sell such Residual
         Certificate to a purchaser selected by the Trustee on such terms as the
         Trustee may choose. Such purported Transferee shall promptly endorse
         and deliver each Residual Certificate in accordance with the
         instructions of the Trustee. Such purchaser may be the Trustee itself
         or any Affiliate of the Trustee. The proceeds of such sale, net of the
         commissions (which may include commissions payable to the Trustee or
         its Affiliates), expenses and taxes due, if any, will be remitted by
         the Trustee to such purported Transferee. The terms and conditions of
         any sale under this clause (iii)(B) shall be determined in the sole
         discretion of the Trustee, and the Trustee shall not be liable to any
         Person having an Ownership Interest in a Residual Certificate as a
         result of its exercise of such discretion.

                  (iv) The Trustee shall make available to the Internal Revenue
         Service and those Persons specified by the REMIC Provisions all
         information necessary to compute any tax imposed (A) as a result of the
         Transfer of an Ownership Interest in a Residual Certificate to any
         Person who is a Disqualified Organization, including the information
         described in Treasury regulations sections 1.860D-1(b)(5) and
         1.860E-2(a)(5) with respect to the "excess inclusions" of such Residual
         Certificate and (B) as a result of any regulated investment company,
         real estate investment trust, common Trust, partnership, trust, estate
         or organization described in Section 1381 of the Code that holds an
         Ownership Interest in a Residual Certificate having as among its record
         holders at any time any Person which is a Disqualified Organization.
         Reasonable compensation for providing such information may be accepted
         by the Trustee.

                  (v) The provisions of this Section 5.02(d) set forth prior to
         this subsection (v) may be modified, added to or eliminated, provided
         that there shall have been delivered to the Trustee and the NIMS
         Insurer at the expense of the party seeking to modify, add to or
         eliminate any such provision the following:

                  (A) written notification from each Rating Agency to the effect
         that the modification, addition to or elimination of such provisions
         will not cause such Rating Agency to downgrade its then-current ratings
         of any Class of Certificates; and



                                      121
<PAGE>

                  (B) an Opinion of Counsel, in form and substance satisfactory
         to the Trustee and the NIMS Insurer, to the effect that such
         modification of, addition to or elimination of such provisions will not
         cause any Trust REMIC to cease to qualify as a REMIC and will not cause
         any Trust REMIC to be subject to an entity-level tax caused by the
         Transfer of any Residual Certificate to a Person that is not a
         Permitted Transferee or a Person other than the prospective transferee
         to be subject to a REMIC-tax caused by the Transfer of a Residual
         Certificate to a Person that is not a Permitted Transferee.

                  The Trustee shall forward to the NIMS Insurer a copy of the
items delivered to it pursuant to (A) and (B) above.

                  (d) Subject to the preceding subsections, upon surrender for
registration of transfer of any Certificate at any office or agency of the
Trustee maintained for such purpose pursuant to Section 8.11, the Trustee shall
execute, authenticate and deliver, in the name of the designated Transferee or
Transferees, one or more new Certificates of the same Class of a like aggregate
Percentage Interest.

                  (f) At the option of the Holder thereof, any Certificate may
be exchanged for other Certificates of the same Class with authorized
denominations and a like aggregate Percentage Interest, upon surrender of such
Certificate to be exchanged at any office or agency of the Trustee maintained
for such purpose pursuant to Section 8.11. Whenever any Certificates are so
surrendered for exchange, the Trustee shall execute, authenticate and deliver,
the Certificates which the Certificateholder making the exchange is entitled to
receive. Every Certificate presented or surrendered for transfer or exchange
shall (if so required by the Trustee) be duly endorsed by, or be accompanied by
a written instrument of transfer in the form satisfactory to the Trustee duly
executed by, the Holder thereof or his attorney duly authorized in writing. In
addition, (i) with respect to each Class R Certificate, the holder thereof may
exchange, in the manner described above, such Class R Certificate for two
separate certificates, each representing such holder's respective Percentage
Interest in the Class R-I Interest and the Class R-II Interest, respectively, in
each case that was evidenced by the Class R Certificate being exchanged and (ii)
with respect to each Class R-X Certificate, the holder thereof may exchange, in
the manner described above, such Class R-X Certificate for two separate
certificates, each representing such holder's respective Percentage Interest in
the Class R-III Interest and the Class R-IV Interest, respectively, in each case
that was evidenced by the Class R-X Certificate being exchanged.

                  (g) No service charge to the Certificateholders shall be made
for any transfer or exchange of Certificates, but the Trustee 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.

                  (h) All Certificates surrendered for transfer and exchange
shall be canceled and destroyed by the Trustee in accordance with its customary
procedures.

                  SECTION 5.03. Mutilated, Destroyed, Lost or Stolen
                                Certificates.

                  If (i) any mutilated Certificate is surrendered to the
Trustee, or the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Certificate, and (ii) there is delivered to
the Trustee and the NIMS Insurer such security or indemnity as may be required
by it to save it harmless, then, in the absence of actual knowledge by the
Trustee that such Certificate has been acquired by a bona fide purchaser or the
Trustee shall execute, authenticate and deliver, in exchange for or in lieu of
any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of
the same Class and of like denomination and Percentage Interest. Upon the
issuance of any new Certificate under this Section, the Trustee may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses (including the fees
and expenses of the Trustee) connected therewith. Any replacement Certificate
issued pursuant to this Section shall constitute complete and indefeasible
evidence of ownership in the applicable REMIC created hereunder, as if
originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

                  SECTION 5.04. Persons Deemed Owners.

                  The Depositor, the Servicer, the NIMS Insurer, the Trustee 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 4.01 and for all other purposes whatsoever,
and none of the Depositor, the Servicer, the NIMS Insurer, the Trustee or any
agent of any of them shall be affected by notice to the contrary.

                  SECTION 5.05. Certain Available Information.

                  On or prior to the date of the first sale of any Private
Certificate to an Independent third party, the Depositor shall provide to the
Trustee ten copies of any private placement memorandum or other disclosure
document used by the Depositor in connection with the offer and sale of such
Certificates. In addition, if any such private placement memorandum or
disclosure document is revised, amended or supplemented at any time following
the delivery thereof to the Trustee, the Depositor promptly shall inform the
Trustee of such event and shall deliver to the Trustee ten copies of the private
placement memorandum or disclosure document, as revised, amended or
supplemented. The Trustee shall maintain at its Corporate Trust Office and shall
make available free of charge during normal business hours for review by any
Holder of a Certificate or any Person identified to the Trustee as a prospective
transferee of a Certificate, originals or copies of the following items: (i) in
the case of a Holder or prospective transferee of a Private Certificate, the
related private placement memorandum or other disclosure document relating to
such Class of Certificates, in the form most recently provided to the Trustee;
and (ii) in all cases, (A) this Agreement and any amendments hereof entered into
pursuant to Section 11.01, (B) all monthly statements required to be delivered
to Certificateholders of the relevant Class pursuant to Section 4.02 since the
Closing Date, and all other notices, reports, statements and written
communications delivered to the Certificateholders of the relevant Class
pursuant to this Agreement since the Closing Date, (C) all certifications
delivered by a Responsible Officer of the Trustee since the Closing Date
pursuant to Section 10.01(h), (D) any and all Officers' Certificates delivered
to the Trustee by the Servicer since the Closing Date to evidence the


                                      123
<PAGE>

Servicer's determination that any Advance or Servicing Advance was, or if made,
would be a Nonrecoverable Advance or Nonrecoverable Servicing Advance,
respectively, and (E) any and all Officers' Certificates delivered to the
Trustee by the Servicer since the Closing Date pursuant to Section 4.04(a).
Copies and mailing of any and all of the foregoing items will be available from
the Trustee upon request at the expense of the Person requesting the same.

                         THE DEPOSITOR AND THE SERVICER

                  SECTION 6.01. Liability of the Depositor and the Servicer.

                  The Depositor and the 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
Servicer and undertaken hereunder by the Depositor and the Servicer herein.

                  SECTION 6.02. Merger or Consolidation of the Depositor or the
                                Servicer.

                  Subject to the following paragraph, the Depositor will 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 Servicer will keep in full effect its existence, rights and franchises as a
federally chartered savings bank under the laws of the United States. The
Depositor and the Servicer each will 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 Mortgage Loans
and to perform its respective duties under this Agreement.

                  The Depositor or the 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 Servicer shall be a party, or any Person
succeeding to the business of the Depositor or the Servicer, shall be the
successor of the Depositor or the 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, that the successor or surviving Person to the Servicer shall
be qualified to service mortgage loans on behalf of Fannie Mae or Freddie Mac;
and provided further that the Rating Agencies' ratings of the Class A
Certificates and the Mezzanine 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).

                  SECTION 6.03. Limitation on Liability of the Depositor, the
                                Servicer and Others.

                  (a) The Servicer (except the Trustee if it is required to
succeed the Servicer hereunder) indemnifies and holds the NIMS Insurer, the
Trustee and the Depositor harmless against any and all claims, losses,
penalties, fines, forfeitures, reasonable legal fees and related costs,
judgments, and any other costs, fees and expenses that the NIMS Insurer, The
Trustee and the Depositor may sustain in any way related to the failure of the
Servicer to perform its duties and service the Mortgage Loans in compliance with
the terms of this Agreement. The Servicer shall immediately notify the NIMS
Insurer, the Trustee and the Depositor if a claim is made that may result in
such claims, losses, penalties, fines, forfeitures, legal fees or related costs,
judgments, or any other costs, fees and expenses, and the Servicer shall assume
(with the consent of the Trustee) the defense of any such claim and pay all
expenses in connection therewith,


                                      125
<PAGE>

including reasonable counsel fees, and promptly pay, discharge and satisfy any
judgment or decree which may be entered against the NIMS Insurer, the Trustee
and/or the Depositor in respect of such claim. The provisions of this Section
6.03 shall survive the termination of this Agreement and the payment of the
outstanding Certificates.

                  (b) None of the Depositor, the NIMS Insurer, the Servicer or
any of the directors, officers, employees or agents of the Depositor or the
Servicer 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 for errors in judgment;
provided, however, that this provision shall not protect the Depositor, the
Servicer or any such person against any breach of warranties, representations or
covenants made herein, or against any specific liability imposed on the Servicer
pursuant hereto, 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, in the case of the Servicer, a breach of the servicing standard set
forth in Section 3.01. The Depositor, the NIMS Insurer and the Servicer and any
director, officer, employee or agent of the Depositor, the NIMS Insurer or the
Servicer may rely in good faith on any document of any kind which is, PRIMA
FACIE, is properly executed and submitted by any Person respecting any matters
arising hereunder. The Depositor, the NIMS Insurer, the Servicer and any
director, officer, employee or agent of the Depositor, the NIMS Insurer or the
Servicer shall be indemnified and held harmless by the Trust Fund against any
loss, liability or expense incurred in connection with (i) any legal action
relating to this Agreement or the Certificates, other than any loss, liability
or expense relating to any specific Mortgage Loan or Mortgage Loans (except as
any such loss, liability or expense shall be otherwise reimbursable pursuant to
this Agreement) or any loss, liability or expense incurred by reason of willful
misfeasance, bad faith or negligence in the performance of duties hereunder or
by reason of its reckless disregard of obligations and duties hereunder or (ii)
any breach of a representation or warranty by the Originator, NC Capital or any
other party regarding the Mortgage Loans. None of the Depositor, the NIMS
Insurer or the 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 and, in its opinion, does not involve it in any expense or
liability; provided, however, that each of the Depositor, the NIMS Insurer and
the Servicer 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, unless the Depositor or the Servicer acts without the consent of
Holders of Certificates entitled to at least 51% of the Voting Rights in the
case of legal actions initiated by the Depositor or the Servicer, 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 NIMS Insurer and the
Servicer shall be entitled to be reimbursed therefor from the Collection Account
as and to the extent provided in Section 3.11, any such right of reimbursement
being prior to the rights of the Certificateholders to receive any amount in the
Collection Account. The Servicer's right to indemnity or reimbursement pursuant
to this Section shall survive any resignation or termination of the Servicer
pursuant to Section 6.04 or 7.01 with respect to any losses, expenses, costs or
liabilities arising prior to such resignation or termination (or arising from
events that occurred prior to such resignation or termination).

                  SECTION 6.04. Limitation on Resignation of the Servicer.

                  Except as otherwise provided herein, the 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 Servicer shall be evidenced by an Opinion of
Counsel to such effect obtained at the expense of the Servicer and delivered to
the Trustee and the NIMS Insurer. No resignation of the Servicer shall become
effective until the Trustee or a successor servicer acceptable to the NIMS
Insurer shall have assumed the Servicer's responsibilities, duties, liabilities
(other than those liabilities arising prior to the appointment of such
successor) and obligations under this Agreement. Any such resignation shall not
relieve the Servicer of responsibility for any of the obligations specified in
Sections 7.01 and 7.02 as obligations that survive the resignation or
termination of the Servicer.

                  Except as expressly provided herein, the Servicer shall not
assign or transfer any of its rights, benefits or privileges hereunder to any
other Person, or delegate to or subcontract with, or authorize or appoint any
other Person to perform any of the duties, covenants or obligations to be
performed by the Servicer hereunder. The foregoing prohibition on assignment
shall not prohibit the Servicer from designating a Sub-Servicer as payee of any
indemnification amount payable to the Servicer hereunder; provided, however,
that as provided in Section 3.06 hereof, no Sub-Servicer shall be a third-party
beneficiary hereunder and the parties hereto shall not be required to recognize
any Sub-Servicer as an indemnitee under this Agreement. If, pursuant to any
provision hereof, the duties of the Servicer are transferred to a successor
Servicer, the entire amount of the Servicing Fee and other compensation payable
to the Servicer pursuant hereto shall thereafter be payable to such successor
Servicer.

                  The Trustee and the Depositor hereby specifically (i) consent
to the pledge and assignment by the Servicer of all of the Servicer's right,
title and interest in, to and under this Agreement to a specified servicing
rights pledgee, for the benefit of certain lenders and (ii) in the event that a
Servicer Event of Default or a Default under the related loan agreement with
such lenders exists or in the event of a Servicer resignation, agree that the
Servicer or its designee may appoint the successor Servicer; provided that at
the time of such appointment, such successor meets the requirements of a
successor Servicer pursuant to Section 7.02(a) hereof and agrees to be subject
to the terms of this Agreement. If, pursuant to any provision hereof, the duties
of the Servicer are transferred to a successor servicer, the entire amount of
the Servicing Fee and other compensation payable to the Servicer pursuant hereto
shall thereafter be payable to such successor servicer.

                  SECTION 6.05. Rights of the Depositor in Respect of the
                                Servicer.

                  The Servicer shall afford (and any Sub-Servicing Agreement
shall provide that each Sub-Servicer shall afford) the Depositor, the NIMS
Insurer and the Trustee, upon reasonable notice, during normal business hours,
access to all records maintained by the Servicer (and any such Sub-Servicer) in
respect of the Servicer's rights and obligations hereunder and access to
officers of the Servicer (and those of any such Sub-Servicer) responsible for
such obligations. Upon request, the Servicer shall furnish to the Depositor, the
NIMS Insurer and the Trustee its (and any such Sub-Servicer's) most recent
financial statements and such other


                                      127
<PAGE>

information relating to the Servicer's capacity to perform its obligations under
this Agreement as it possesses (and that any such Sub-Servicer possesses). To
the extent such information is not otherwise available to the public, the
Depositor, the NIMS Insurer and the Trustee shall not disseminate any
information obtained pursuant to the preceding two sentences without the
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 and the
Trustee or the Trust Fund, and in any case, the Depositor, the NIMS Insurer or
the Trustee, as the case may be, shall use its best efforts to assure the
confidentiality of any such disseminated non-public information. Nothing in this
Section shall limit the obligation of the Servicer to observe any applicable law
prohibiting disclosure of information regarding the Mortgagors (absent proof
that it is in compliance with applicable law) and the failure of the Servicer to
provide access as provided in this Section as a result of such obligation shall
not constitute a breach of this Section. Nothing in this Section shall require
the Servicer to collect, create, collate or otherwise generate any information
that it does not generate in its usual course of business. The Servicer shall
not be required to make copies of or ship documents to any party unless
provisions have been made for the reimbursement of the costs thereof. The
Depositor may, but is not obligated to, enforce the obligations of the Servicer
under this Agreement and may, but is not obligated to, perform, or cause a
designee to perform, any defaulted obligation of the Servicer under this
Agreement or exercise the rights of the Servicer under this Agreement; provided
that the 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 Servicer and is not obligated to supervise the performance
of the Servicer under this Agreement or otherwise.

                  SECTION 6.06. Duties of the Credit Risk Manager.

                  For and on behalf of the Depositor, the Credit Risk Manager
will provide reports and recommendations concerning certain delinquent and
defaulted Mortgage Loans, and as to the collection of any Prepayment Charges
with respect to the Mortgage Loans. Such reports and recommendations will be
based upon information provided to the Credit Risk Manager pursuant to the
Credit Risk Management Agreement, and the Credit Risk Manager shall look solely
to the Servicer for all information and data (including loss and delinquency
information and data) relating to the servicing of the related Mortgage 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 Servicer, the Trustee, the NIMS Insurer 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 6.07. 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 the Servicer under the Credit Risk
Management Agreement, or for errors in judgment; provided, however, that this
provision shall


                                      128
<PAGE>

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 the Servicer pursuant to the applicable
Credit Risk Management Agreement in the performance of its duties thereunder and
hereunder.

                  SECTION 6.08. Removal of the Credit Risk Manager.

                  The Credit Risk Manager may be removed as Credit Risk Manager
by Certificateholders holding not less than 66 2/3% of the Voting Rights in the
Trust Fund, 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 7.01. Servicer Events of Default.

         Remittance Date pursuant to Section 4.03) required to be made under the
         terms of the Certificates and this Agreement which continues unremedied
         for a period of one Business Day after the date upon which written
         notice of such failure, requiring the same to be remedied, shall have
         been given to the Servicer by the Depositor or the Trustee (in which
         case notice shall be provided by telecopy), or to the Servicer, the
         Depositor and the Trustee by the NIMS Insurer or the Holders of
         Certificates entitled to at least 25% of the Voting Rights; or

                  (ii) any failure on the part of the Servicer duly to observe
         or perform in any material respect any other of the covenants or
         agreements on the part of the Servicer contained in this Agreement, or
         the breach by the Servicer of any representation and warranty contained
         in Section 2.05, which continues unremedied for a period of 30 days (or
         if such failure or breach cannot be remedied within 30 days, then such
         remedy shall have been commenced within 30 days and diligently pursued
         thereafter; provided, however, that in no event shall such failure or
         breach be allowed to exist for a period of greater than 90 days) after
         the earlier of (i) the date on which written notice of such failure,
         requiring the same to be remedied, shall have been given to the

         Servicer Remittance Date required to be made from its own funds
         pursuant to Section 4.03 which continues unremedied until 3:00 p.m. New
         York time on the Business Day following the Servicer Remittance Date.

                  If a Servicer Event of Default described in clauses (i)
through (vi) of this Section shall occur, then, and in each and every such case,
so long as such 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 entitled to at least 51% of Voting Rights, or at the direction of
the NIMS Insurer, the Trustee shall, by notice in writing to the Servicer (and
to the Depositor if given by the Trustee or to the Trustee if given by the
Depositor), terminate all of the rights and obligations of the Servicer in its
capacity as Servicer under this Agreement, to the extent permitted by law, and
in and to the Mortgage Loans and the proceeds thereof. If a Servicer Event of
Default described in clause (vii) hereof shall occur, the Trustee shall, by
notice in writing to the Servicer, the Depositor and the NIMS Insurer, terminate
all of the rights and obligations of the Servicer in its capacity as Servicer
under this Agreement and in and to the Mortgage Loans and the proceeds thereof.
Subject to Section 7.02 hereof, on or after the receipt by the Servicer of such
written notice, all authority and power of the Servicer under this Agreement,
whether with respect to the Certificates (other than as a Holder of any
Certificate) or the Mortgage 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 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


                                      130
<PAGE>

and endorsement or assignment of the Mortgage Loans and related documents, or
otherwise. The Servicer agrees to promptly (and in any event no later than ten
Business Days subsequent to such notice) provide the Trustee with all documents
and records requested by it to enable it to assume the Servicer's functions
under this Agreement, and to cooperate with the Trustee in effecting the
termination of the Servicer's responsibilities and rights under this Agreement,
including, without limitation, the transfer within one Business Day to the
Trustee for administration by it of all cash amounts which at the time shall be
or should have been credited by the Servicer to the Collection Account held by
or on behalf of the Servicer, the Distribution Account or any REO Account or
Servicing Account held by or on behalf of the Servicer or thereafter be received
with respect to the Mortgage Loans or any REO Property serviced by the Servicer;
provided, however, that the 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 6.03, notwithstanding any
such termination, with respect to events occurring prior to such termination.
For purposes of this Section 7.01, the Trustee shall not be deemed to have
knowledge of a Servicer Event of Default unless a Responsible Officer of the
Trustee assigned to and working in the Corporate Trust Office has actual
knowledge thereof or unless written notice of any event which is in fact such a
Servicer Event of Default is received by the Trustee and such notice references
the Certificates, the Trust Fund or this Agreement.

                  SECTION 7.02. Trustee to Act; Appointment of Successor.

                  (a) From the time the Servicer (and the Trustee, if notice is
sent by the Holders of Certificates entitled to at least 51% of Voting Rights or
the NIMS Insurer) receives a notice of termination, the Trustee (or such other
successor Servicer as is acceptable to the NIMS Insurer) shall be the successor
in all respects to the Servicer in its capacity as Servicer under this Agreement
and the transactions set forth or provided for herein, and all the
responsibilities, duties and liabilities relating thereto and arising thereafter
shall be assumed by the Trustee (except for any representations or warranties of
the Servicer under this Agreement, the responsibilities, duties and liabilities
contained in Section 2.05 (other than with respect to Section 2.05(x)) and the
obligation to deposit amounts in respect of losses pursuant to Section 3.12) by
the terms and provisions hereof; provided, however, the Trustee shall
immediately assume the Servicer's obligations to make Advances pursuant to
Section 4.03; provided, further, 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 4.03; and provided further, that any failure to perform such
duties or responsibilities caused by the Servicer's failure to provide
information required by Section 7.01 shall not be considered a default by the
Trustee as successor to the Servicer hereunder. It is understood and
acknowledged by the parties hereto that there will be a period of transition
(not to exceed 90 days) before the transition of servicing obligations is fully
effective. As compensation therefor, the Trustee shall be entitled to the
Servicing Fee and all funds relating to the Mortgage Loans to which the Servicer
would have been entitled if it had continued to act hereunder. Notwithstanding
the above and subject to Section 7.02(b) below, the Trustee 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 entitled to at least 51% of the Voting Rights or the
NIMS Insurer so request in writing to the Trustee, promptly appoint or petition
a court of competent jurisdiction to appoint, an established


                                      131
<PAGE>

mortgage loan servicing institution acceptable to each Rating Agency and the
NIMS Insurer and having a net worth of not less than $15,000,000, as the
successor to the Servicer under this Agreement in the assumption of all or any
part of the responsibilities, duties or liabilities of the Servicer under this
Agreement.

                  Pending appointment of a successor to the Servicer hereunder,
unless the Trustee is prohibited by law from so acting, the Trustee shall act in
such capacity as hereinabove provided. In connection with such appointment and
assumption, the successor shall be entitled to receive compensation out of
payments on Mortgage Loans in an amount equal to the compensation which the
Servicer would otherwise have received pursuant to Section 3.18 (or such other
compensation as the Trustee and such successor shall agree, not to exceed the
Servicing Fee). The appointment of a successor Servicer shall not affect any
liability of the predecessor Servicer which may have arisen under this Agreement
prior to its termination as Servicer to pay any deductible under an insurance
policy pursuant to Section 3.14 or to indemnify the NIMS Insurer pursuant to
Section 6.03, nor shall any successor Servicer be liable for any acts or
omissions of the predecessor Servicer or for any breach by such Servicer of any
of its representations or warranties contained herein or in any related document
or agreement. The Trustee and such successor shall take such action, consistent
with this Agreement, as shall be necessary to effectuate any such succession.
All reasonable Servicing Transfer Costs shall be paid by the predecessor
Servicer upon presentation of reasonable documentation of such costs, and if
such predecessor Servicer defaults in its obligation to pay such costs, such
costs shall be paid by the successor Servicer or the Trustee (in which case the
successor Servicer or the Trustee, as applicable, shall be entitled to
reimbursement therefor from the assets of the Trust Fund).

                  (b) No appointment of a successor to the Servicer under this
Agreement shall be effective until the assumption by the successor of all of the
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 Mortgage
Loans as it and such successor shall agree; provided, however, that no such
compensation shall be in excess of that permitted the 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 Servicer under this
Agreement or the Trustee shall act in such capacity as hereinabove provided.

                  Any successor to the Servicer, including the Trustee, shall
during the term of its service as servicer continue to service and administer
the Mortgage Loans for the benefit of Certificateholders, and maintain in force
a policy or policies of insurance covering errors and omissions in the
performance of its obligations as Servicer hereunder and a fidelity bond in
respect of its officers, employees and agents to the same extent as the Servicer
is so required pursuant to Section 3.14.

                  (c) Notwithstanding any provision in this Agreement to the
contrary, for a period of 30 days following the date on which the Servicer shall
have received a notice of a Servicer Event of Default pursuant to Section 7.01,
or a default under a loan agreement pursuant to Section 6.04 or a Servicer
resignation pursuant to Section 6.04, the terminated Servicer or its


                                      132
<PAGE>

designee may appoint a successor Servicer that satisfies the eligibility
criteria of a successor Servicer set forth above; provided that such successor
Servicer agrees to fully effect the servicing transfer within 90 days following
the termination of the Servicer and to make all Advances that would otherwise be
made by the Trustee under Section 7.01 as of the date of such appointment. Any
proceeds received in connection with the appointment of such successor Servicer
shall be the property of the terminated Servicer or its designee.
Notwithstanding the foregoing, in the event of a Servicer Event of Default
pursuant to Section 7.01(a)(vii), either (i) the Servicer shall remit the amount
of the required Advance by 3:00 p.m. New York time on the Business Day following
the Servicer Remittance Date or (ii) by 3:00 p.m. New York time on the Business
Day following the Servicer Remittance Date, the Servicer shall have appointed a
successor Servicer that satisfies the eligibility criteria of a successor
Servicer set forth above and that has remitted the amount of the required
Advance to the Trustee. If the Servicer fails to adhere to the requirements set
forth in the immediately preceding sentence, the Trustee shall be the successor
in all respects to the Servicer in its capacity as Servicer under this Agreement
and shall immediately assume the Servicer's obligations to make Advances. In no
event shall the termination of the Servicer under this Agreement result in any
diminution of the Servicer's right to reimbursement for any outstanding Advances
or Servicing Advances or accrued and unpaid Servicing Fees due such Servicer at
the time of termination. Reimbursement of unreimbursed Advances and Servicing
Advances and accrued and unpaid Servicing Fees shall be made on a FIFO,
loan-by-loan basis. The Servicer shall continue to be entitled to the benefits
of Section 6.03 hereof related to indemnification, notwithstanding any
termination hereunder.

                  (d) In connection with the termination or resignation of the
Servicer hereunder, either (i) the successor Servicer, including the Trustee if
the Trustee is acting as successor Servicer, shall represent and warrant that it
is a member of MERS in good standing and shall agree to comply in all material
respects with the rules and procedures of MERS in connection with the servicing
of the Mortgage Loans that are registered with MERS, in which case the
predecessor Servicer shall cooperate with the successor Servicer in causing MERS
to revise its records to reflect the transfer of servicing to the successor
Servicer as necessary under MERS' rules and regulations, or (ii) the predecessor
Servicer shall cooperate with the successor Servicer in causing MERS to execute
and deliver an assignment of Mortgage in recordable form to transfer the
Mortgage from MERS to the Trustee and to execute and deliver such other notices,
documents and other instruments as may be necessary or desirable to effect a
transfer of such Mortgage Loan or servicing of such Mortgage Loan on the MERS(R)
System to the successor Servicer. The predecessor Servicer shall file or cause
to be filed any such assignment in the appropriate recording office. The
predecessor Servicer shall bear any and all fees of MERS, costs of preparing any
assignments of Mortgage, and fees and costs of filing any assignments of
Mortgage that may be required under this Section 7.02(d).

                  SECTION 7.03. Notification to Certificateholders.

                  (a) Upon any termination of the Servicer pursuant to Section
7.01 above or any appointment of a successor to the Servicer pursuant to Section
7.02 above, the Trustee shall give prompt written notice thereof to the Credit
Risk Manager and the NIMS Insurer and to the Certificateholders at their
respective addresses appearing in the Certificate Register.



                                      133
<PAGE>

                  (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 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 the Credit Risk Manager, the NIMS Insurer and
to all Holders of Certificates notice of each such occurrence, unless such
default or Servicer Event of Default shall have been cured or waived.

                  SECTION 7.04. Waiver of Servicer Events of Default.

                  The Holders representing at least 66% of the Voting Rights
(with the consent of the NIMS Insurer) evidenced by all Classes of Certificates
affected by any default or Servicer Event of Default hereunder may waive such
default or Servicer Event of Default; provided, however, that a default or
Servicer Event of Default under clause (i) or (vii) of Section 7.01 may be
waived only by all of the Holders of the Regular Certificates (with the consent
of the NIMS Insurer). Upon any such waiver of a default or Servicer Event of
Default, such default or Servicer Event of Default shall cease to exist and
shall be deemed to have been remedied for every purpose hereunder. No such
waiver shall extend to any subsequent or other default or Servicer Event of
Default or impair any right consequent thereon except to the extent expressly so
waived. Notice of any such waiver shall be given by the Trustee to the Rating
Agencies and the NIMS Insurer.

                  SECTION 7.05. Survivability of Servicer Liabilities.

                  Notwithstanding anything herein to the contrary, upon
termination of the Servicer hereunder, any liabilities of the Servicer which
accrued prior to such termination shall survive such termination.

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

                  SECTION 8.01. Duties of Trustee

                  The Trustee prior to the occurrence of a Servicer Event of
Default and after the curing of all Servicer Events of Default which may have
occurred, undertakes to perform such duties and only such duties as are
specifically set forth in this Agreement. During a 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 their 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.

                  The Trustee upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to it, which are specifically required to be furnished pursuant to any provision
of this Agreement, shall examine them to determine whether they conform to the
requirements of this Agreement; provided, however, that the Trustee will not be
responsible for the accuracy or content of any such resolutions, certificates,
statements, opinions, reports, documents or other instruments. If any such
instrument is found not to conform to the requirements of this Agreement in a
material manner, it shall take such action as it deems appropriate to have the
instrument corrected, and if the instrument is not corrected to its
satisfaction, it will provide notice thereof to the Certificateholders and the
NIMS Insurer.

                  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 Servicer Event of Default,
         and after the curing of all such Servicer Events of Default which may
         have occurred, the duties and obligations of the Trustee shall be
         determined solely by the express provisions of this Agreement, the
         Trustee 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, and in the absence of bad faith on the part of the Trustee,
         the Trustee may conclusively rely, as to the truth of the statements
         and the correctness of the opinions expressed therein, upon any
         certificates or opinions furnished to the Trustee that conform to the
         requirements of this Agreement;

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

                  (iii) The Trustee shall not be personally liable with respect
         to any action taken, suffered or omitted to be taken by it in good
         faith in accordance with the direction of the NIMS Insurer or the
         Holders of Certificates entitled to at least 25% of the Voting Rights
         relating to the time, method and place of conducting any proceeding for
         any remedy


                                      135
<PAGE>

         available to it or exercising any trust or power conferred upon it
         under this Agreement; and

                  (iv) The Trustee shall not be required to take notice or be
         deemed to have notice or knowledge of any default or Master Servicer
         Event of Termination unless a Responsible Officer of the Trustee at the
         Corporate Trust Office obtains actual knowledge of such failure or the
         Trustee receives written notice of such failure from the Depositor, the
         Servicer or the Holders of Certificates evidencing not less than 51% of
         the Voting Rights.

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

                  SECTION 8.02. Certain Matters Affecting the Trustee

                  (a) Except as otherwise provided in Section 8.01:

                           (i) The Trustee 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 may consult with counsel and 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 Opinion of Counsel;

                           (iii) The Trustee shall not be under any obligation
                  to exercise any of the trusts or powers vested in it by this
                  Agreement or to institute, conduct or defend any litigation
                  hereunder or in relation hereto at the request, order or
                  direction of any of the Certificateholders or the NIMS
                  Insurer, pursuant to the provisions of this Agreement, unless
                  such Certificateholders or the NIMS Insurer, as applicable,
                  shall have offered to the Trustee reasonable security or
                  indemnity 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 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;



                                      136
<PAGE>

                           (iv) The Trustee shall not be personally liable for
                  any action taken, suffered or omitted by it in good faith and
                  believed by it to be authorized or within the discretion or
                  rights or powers conferred upon it by this Agreement;

                           (v) Prior to the occurrence of a Servicer Event of
                  Default hereunder and after the curing of all Servicer Events
                  of Default which may have occurred, the Trustee shall not be
                  bound to make any investigation into the facts or matters
                  stated in any resolution, certificate, statement, instrument,
                  opinion, report, notice, request, consent, order, approval,
                  bond or other paper or document, unless requested in writing
                  to do so by the NIMS Insurer or the Holders of Certificates
                  entitled to at least 25% of the Voting Rights; provided,
                  however, that if the payment within a reasonable time to the
                  Trustee, of the costs, expenses or liabilities likely to be
                  incurred by it in the making of such investigation is, in the
                  opinion of the Trustee, not reasonably assured to the Trustee,
                  by such Certificateholders, the Trustee may require reasonable
                  indemnity against such expense, or liability from such
                  Certificateholders or the NIMS Insurer, as applicable, 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; provided, that
                  the Trustee shall not be responsible for any negligence or
                  willful misconduct on the part of the Custodian or any such
                  agents or attorneys appointed by it with due care; and

                           (vii) The Trustee shall not be personally liable for
                  any loss resulting from the investment of funds held in the
                  Collection Account at the direction of the Servicer pursuant
                  to Section 3.12.

                  (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 8.03. Trustee not Liable for Certificates or Mortgage
                                Loans.

                  The recitals contained herein and in the Certificates (other
than the signature of the Trustee, the authentication of the Trustee 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 the Trustee shall not assume any
responsibility for their correctness. The Trustee shall not make 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 Trustee, and authentication of the
Trustee on the Certificates) or of any Mortgage Loan or related document or of
MERS or the MERS(R) System. The Trustee shall not be accountable for the use or
application by the Depositor of any of the Certificates or of the proceeds of
such Certificates, or for the use or application of any funds paid to the
Depositor or the Servicer in respect of the Mortgage Loans


                                      137

or deposited in or withdrawn from the Collection Account by the Servicer, other
than any funds held by or on behalf of the Trustee in accordance with Section
3.10.

                  SECTION 8.04. Trustee May Own Certificates.

                  The Trustee in its individual capacity or any other capacity
may become the owner or pledgee of Certificates with the same rights it would
have if it were not the Trustee.

                  SECTION 8.05. Trustee's Fees and Expenses.

                  The Trustee shall be entitled to withdraw from the
Distribution Account, pursuant to Section 3.11(b), on each Distribution Date and
pay to itself the Trustee Fee. The Trustee and any director, officer, employee
or agent of the Trustee, shall be indemnified by the Trust Fund and held
harmless against any loss, liability or expense (not including expenses,
disbursements and advances incurred or made by the Trustee, including the
compensation and the expenses and disbursements of its agents and counsel, in
the ordinary course of the Trustee's performance in accordance with the
provisions of this Agreement) incurred by the Trustee arising out of or in
connection with the acceptance or administration of its obligations and duties
under this Agreement up to a limit of $600,000 per calender year, other than any
loss, liability or expense (i) resulting from any breach of the Servicer's
obligations in connection with this Agreement, (ii) that constitutes a specific
liability of the Trustee pursuant to Section 10.01(g) or (iii) any loss,
liability or expense incurred by reason of willful misfeasance, bad faith or
negligence in the performance of duties hereunder or by reason of reckless
disregard of obligations and duties hereunder as a result of a breach of the
Trustee's obligations under Article X hereof. Notwithstanding anything herein to
the contrary, the Trustee shall be reimbursed from the Trust Fund for all
Servicing Transfer Costs without regard to the annual limitation.

                  SECTION 8.06. Eligibility Requirements for Trustee

                  The Trustee hereunder shall at all times be a corporation or
an association (other than the Depositor, the Originator, NC Capital, the
Seller, the 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 shall cease to be eligible in accordance with the provisions of this
Section, the Trustee shall resign immediately in the manner and with the effect
specified in Section 8.07.

                  SECTION 8.07. Resignation and Removal of the Trustee

                  The Trustee may at any time resign and be discharged from the
trust hereby created by giving written notice thereof to the Depositor, the NIMS
Insurer, the Servicer and the


                                      138
<PAGE>

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

                  If at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.06 and shall fail to resign after
written request therefor by the Depositor or the NIMS Insurer, or if at any time
the Trustee shall become incapable of acting, or shall be adjudged bankrupt or
insolvent, or a receiver of the Trustee or of its property shall be appointed,
or any public officer shall take charge or control of the Trustee or of its
property or affairs for the purpose of rehabilitation, conservation or
liquidation, then the Depositor or the NIMS Insurer may remove the and appoint a
successor trustee acceptable to the NIMS Insurer by written instrument, in
duplicate, which instrument shall be delivered to the Trustee so removed and to
the successor trustee. A copy of such instrument shall be delivered to the
Certificateholders, the Trustee and the Servicer by the Depositor.

                  The Holders of Certificates entitled to at least 51% of the
Voting Rights (or the NIMS Insurer upon failure of the Trustee to perform its
obligations hereunder) may at any time remove the Trustee and appoint a
successor trustee acceptable to the NIMS Insurer by written instrument or
instruments, in triplicate, signed by such Holders or their attorneys-in-fact
duly authorized, one complete set of which instruments shall be delivered to the
Depositor, one complete set to the Trustee so removed and one complete set to
the successor so appointed. A copy of such instrument shall be delivered to the
Certificateholders and the Servicer by the Depositor.

                  Any resignation or removal of the Trustee and appointment of a
successor trustee, pursuant to any of the provisions of this Section shall not
become effective until acceptance of appointment by the successor trustee as
provided in Section 8.08. Notwithstanding the foregoing, in the event the
Trustee is unable to continue to perform its obligations pursuant to the terms
of this Agreement prior to the appointment of a successor, the Trustee shall be
obligated to perform such obligations until a new trustee is appointed. Such
performance shall be without prejudice to any claim by a party hereto or
beneficiary hereof resulting from the Trustee's breach of its obligations
hereunder.

                  SECTION 8.08. Successor Trustee

                  Any successor trustee appointed as provided in Section 8.07
shall execute, acknowledge and deliver to the Depositor, the NIMS Insurer and
its predecessor trustee an instrument accepting such appointment hereunder, and
thereupon the resignation or removal of the predecessor trustee shall become
effective and such successor trustee, without any further act, deed or
conveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with the like effect as if originally
named as trustee herein. The predecessor trustee shall deliver to the successor
trustee all Mortgage Files and related documents and statements to the extent
held by it hereunder, as well as all moneys, held


                                      139
<PAGE>

by it hereunder (other than any Mortgage Files at the time held by the
Custodian, which Custodian shall become the agent of any successor trustee
hereunder), and the Depositor and the predecessor trustee 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 all
such rights, powers, duties and obligations.

                  No successor trustee shall accept appointment as provided in
this Section unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 8.06 and the appointment of such
successor trustee shall not result in a downgrading of any Class of Certificates
by any Rating Agency, as evidenced by a letter from each Rating Agency.

                  Upon acceptance of appointment by a successor trustee, as
provided in this Section, the Depositor shall mail notice of the succession of
such trustee hereunder to 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, the
successor trustee shall cause such notice to be mailed at the expense of the
Depositor.

                  SECTION 8.09. Merger or Consolidation of Trustee.

                  Any corporation or association into which either the Trustee
may be merged or converted or with which it may be consolidated or any
corporation or association resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any corporation or
association succeeding to the business of the Trustee shall be the successor of
the Trustee hereunder; provided such corporation or association shall be
eligible under the provisions of Section 8.06, 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 and the NIMS Insurer 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, 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. Any such co-trustee or separate trustee shall be subject to the
written approval of the NIMS Insurer. If the NIMS Insurer shall not have joined
in such appointment within 15 days after the receipt by it of a request to do
so, the Trustee alone shall have the power to make such appointment. No
co-trustee or separate trustee hereunder shall be required to meet the terms of
eligibility as a successor trustee under Section 8.06 hereunder and no notice to
Holders of Certificates of the appointment of co-trustee(s) or separate
trustee(s) shall be required under Section 8.08 hereof.



                                      140
<PAGE>

                  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 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 and a copy thereof given to the NIMS Insurer.

                  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; Appointment of
                                Custodian.

                  The Trustee will appoint an office or agency in the City of
St. Paul, Minnesota 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 Trustee in respect of the Certificates and this
Agreement may be served.

                  The Trustee may, with the consent of the Depositor, the
Servicer and the NIMS Insurer, appoint the Custodian to hold all or a portion of
the Mortgage Files as agent for the Trustee. The appointment of the Custodian
may at any time be terminated and a substitute Custodian appointed therefor upon
the reasonable request of the Servicer or the NIMS Insurer to the Trustee, the
consent to which shall not be unreasonably withheld. The Trustee initially
appoints U.S. Bank National Association as Custodian, and the Depositor and the
Servicer each consent to such appointment. The Custodian shall be a depository
institution or trust company subject to supervision by federal or state
authority, shall have combined capital and surplus of at least $10,000,000 and
shall be qualified to do business in the jurisdiction in which it holds any
Mortgage File. Subject to Section 8.02(a), in no event shall the appointment of
the Custodian diminish the obligations of the Trustee hereunder.

                  SECTION 8.12. Representations and Warranties.

                  The Trustee hereby represents and warrants to the Servicer and
the Depositor, as of the Closing Date, that:

                  (i) It is a national banking association duly organized,
         validly existing and in good standing under the laws of the United
         States of America.

                  (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 association 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 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.

                                   ARTICLE IX

                                   TERMINATION

                  SECTION 9.01. Termination Upon Repurchase or Liquidation of
                                All Mortgage Loans.

                  (a) Subject to Section 9.02, the respective obligations and
responsibilities under this Agreement of the Depositor, the Servicer and the
Trustee (other than the indemnification obligations of the Servicer pursuant to
Section 6.03 and of the Servicer to make remittances to the Trustee and the
Trustee to make payments in respect of the REMIC I Regular Interests and 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 Mortgage 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 Mortgage Loan or REO Property
remaining in REMIC I; provided, however, that in no event shall the trust
created hereby continue beyond the earlier of (a) 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 or (b) the Latest Possible Maturity Date as defined in the
Preliminary Statement. Subject to Section 3.10 hereof, the purchase by the
Terminator of all Mortgage Loans and each REO Property remaining in REMIC I
shall be at a price (the "Termination Price") equal to the greater of (i) the
Stated Principal Balance of the Mortgage Loans and the appraised value of any
REO Properties, such appraisal to be conducted by an Independent appraiser
mutually agreed upon by the Terminator and the Trustee in their reasonable
discretion and (ii) the fair market value of all of the assets of REMIC I (as
determined by the Terminator and the Trustee, as of the close of business on the
third Business Day next preceding the date upon which notice of any such
termination is furnished to Certificateholders pursuant to the third paragraph
of this Section 9.01) in each case, plus accrued and unpaid interest thereon at
the weighted average of the Mortgage Rates through the end of the Due Period
preceding the final Distribution Date, plus unreimbursed Advances, Servicing
Advances, any unpaid Servicing Fees and Trustee Fees allocable to such Mortgage
Loans and REO Properties, any accrued and unpaid Net WAC Rate Carryover Amount;
provided, however, such option may only be exercised if (i) the Termination
Price is sufficient to pay all interest accrued on, as well as amounts necessary
to retire the principal balance of, each class of notes issued pursuant to the
Indenture and any remaining amounts owed to the trustee under the Indenture and
the NIMS Insurer on the date such notes are retired and (ii) the fair market
value of the Mortgage Loans and REO Properties determined as described above is
at least equal to the Stated Principal Balance of the Mortgage Loans (after
giving effect to scheduled payments of principal due during the related Due
Period, to the extent received or advanced, and unscheduled collections of
principal received during the related Prepayment Period) and the appraised value
of the REO Properties.

                  (b) The majority holder of the Class CE Certificates (so long
as such holder is not an affiliate of the Seller) or if such majority holder
fails to exercise such right, the Servicer (or if the Servicer fails to exercise
such right, the NIMS Insurer) shall have the right (the party exercising such
right, the "Terminator"), to purchase all of the Mortgage Loans and each REO


                                      143
<PAGE>

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 Mortgage Loans and each REO
Property remaining in REMIC I pursuant to clause (i) above only if the aggregate
Stated Principal Balance of the Mortgage 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 Stated Principal Balance of the Mortgage Loans as of the Cut-off
Date. By acceptance of the Residual Certificates, the Holder of the Residual
Certificates agrees for so long as any notes insured by the NIMS Insurer and
secured by all or a portion of the Class CE, Class P or Class R Certificates are
outstanding, in connection with any termination hereunder, to assign and
transfer any amounts in excess of par, and to the extent received in respect of
such termination, to pay any such amounts to the Holders of the Class CE
Certificates.

                  (c) Notice of the liquidation of the Certificates shall be
given promptly by the Trustee by letter to Certificateholders and the NIMS
Insurer mailed (a) in the event such notice is given in connection with the
purchase of the Mortgage Loans and each REO Property by the Terminator, not
earlier than the 10th day and not later than the 20th 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 payment in respect
of the REMIC I Regular Interests and the Certificates will be made upon
presentation and surrender of the related Certificates at the office of the
Trustee therein designated, (ii) the amount of any such final payment, (iii)
that no interest shall accrue in respect of the REMIC I Regular Interests or the
Certificates from and after the 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 Trustee. In
the event such notice is given in connection with the purchase of all of the
Mortgage Loans and each REO Property remaining in REMIC I by the Terminator, the
Terminator shall deliver to the Trustee 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 Termination Price. The Trustee shall remit to the Servicer
from such funds deposited in the Distribution Account (i) any amounts which the
Servicer would be permitted to withdraw and retain from the Collection Account
pursuant to Section 3.11 and (ii) any other amounts otherwise payable by the
Trustee to the Servicer from amounts on deposit in the Distribution Account
pursuant to the terms of this Agreement, in each case prior to making any final
distributions pursuant to Section 10.01(d) below. Upon certification to the
Trustee by the Terminator of the making of such final deposit, the Trustee shall
promptly release to the Terminator the Mortgage Files for the remaining Mortgage
Loans, and the Trustee shall execute all assignments, endorsements and other
instruments necessary to effectuate such transfer.

                  (d) Upon presentation of the Certificates by the
Certificateholders on the final Distribution Date, the Trustee shall distribute
to each Certificateholder so presenting and surrendering its Certificates the
amount otherwise distributable on such Distribution Date in accordance with
Section 4.01 in respect of the Certificates so presented and surrendered. 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


                                      144
<PAGE>

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 9.01 shall not have been
surrendered for cancellation within six months after the time specified in such
notice, the Trustee 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 Trustee 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 Fund. If within one year after the final notice any such
Certificates shall not have been surrendered for cancellation, the Trustee shall
pay to UBS Securities LLC, 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 Trustee as a result of such Certificateholder's failure to surrender its
Certificate(s) for final payment thereof in accordance with this Section 9.01.
Any such amounts held in trust by the Trustee shall be held in an Eligible
Account and the Trustee may direct any depository institution maintaining such
account to invest the funds in one or more Permitted Investments. All income and
gain realized from the investment of funds deposited in such accounts held in
trust by the Trustee shall be for the benefit of the Trustee; provided, however,
that the Trustee shall deposit in such account the amount of any loss of
principal incurred in respect of any such Permitted 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 9.02. Additional Termination Requirements.

                  (a) In the event that the Terminator purchases all the
Mortgage Loans and each REO Property or the final payment on or other
liquidation of the last Mortgage Loan or REO Property remaining in REMIC I
pursuant to Section 9.01, the Trust Fund shall be terminated in accordance with
the following additional requirements, unless the Trustee and the Servicer have
received an Opinion of Counsel, which Opinion of Counsel shall be at the expense
of the Terminator (or in connection with a termination resulting from the final
payment on or other liquidation of the last Mortgage Loan or REO Property
remaining in REMIC I, which Opinion of Counsel shall be at the expense of the
person seeking nonadherence to the following additional requirements but which
in no event shall be at the expense of the Trust Fund or, unless it is the
person seeking nonadherence to the following additional requirements, the
Servicer or the Trustee), to the effect that the failure of REMIC I to comply
with such additional requirements of this Section 9.02 will not (A) result in
the imposition on the Trust Fund of taxes on "prohibited transactions," as
described in Section 860F of the Code, or (B) cause REMIC I to fail to qualify
as a REMIC at any time that any Certificate is outstanding:

                  (i) The Trustee shall specify the first day in the 90-day
         liquidation period in a statement attached to each Trust REMIC's final
         Tax Return pursuant to Treasury regulation Section 1.860F-1 and shall
         satisfy all requirements of a qualified liquidation


                                      145
<PAGE>

         under Section 860F of the Code and any regulations thereunder, as
         evidenced by an Opinion of Counsel obtained 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
         Trustee 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 Trustee 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 Terminator, the Depositor shall
prepare or cause to be prepared the documentation required in connection with
the adoption of a plan of liquidation of each Trust REMIC pursuant to this
Section 9.02.

                  (c) By their acceptance of Certificates, the Holders thereof
hereby agree to authorize the Trustee to specify the 90-day liquidation period

                                REMIC PROVISIONS

                  SECTION 10.01. REMIC Administration.

                  (a) The Trustee shall elect to treat each Trust REMIC as a
REMIC under the Code and, if necessary, under applicable state law. Each such
election will be made by the Trustee 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-I Interest shall be designated as the Residual Interest in REMIC I.
The Class A Certificates, the Mezzanine Certificates, the Class CE Interest and
the Class P Interest shall be designated as the Regular Interests in REMIC II
and the Class R-II Interest shall be designated as the Residual Interest in
REMIC II. The CE Certificates shall be designated as the Regular Interests in
REMIC III and the Class R-III Interest shall be designated as the Residual
Interest in REMIC III. The P Certificates shall be designated as the Regular
Interests in REMIC IV and the Class R-IV Interest shall be designated as the
Residual Interest in REMIC IV. The Trustee shall not permit the creation of any
"interests" in any Trust REMIC (within the meaning of Section 860G of the Code)
other than the REMIC I Regular Interests, the Class CE Interest, the Class P
Interest 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 Trustee 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
any Trust 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 Trustee, as agent for each Trust REMIC's
tax matters person shall (i) act on behalf of the Trust Fund in relation to any
tax matter or controversy involving any Trust 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 the Residual Certificates shall be
designated, in the manner provided under Treasury Regulations Section
1.860F-4(d) and Treasury Regulations Section 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 Trustee or an Affiliate as
its agent to perform all of the duties of the tax matters person for the Trust
Fund.

                  (d) The Trustee shall prepare, sign and file all of the Tax
Returns (including Form 8811, which must be filed within 30 days following the
Closing Date) in respect of each Trust REMIC. The expenses of preparing and
filing such returns shall be borne by the Trustee without any right of
reimbursement therefor.



                                      147
<PAGE>

                  (e) The Trustee shall perform on behalf of each Trust REMIC
all reporting and other tax compliance duties that are the responsibility of
such REMIC under the Code, the REMIC Provisions or other compliance guidance
issued by the Internal Revenue Service or any state or local taxing authority.
Among its other duties, as required by the Code, the REMIC Provisions or other
such compliance guidance, the Trustee 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, (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 will
serve as the representative of each Trust REMIC. The Depositor shall provide or
cause to be provided to the Trustee, within ten (10) days after the Closing
Date, all information or data that the Trustee 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) The Trustee shall take such action and shall cause each
Trust REMIC to take such action as shall be necessary to create or maintain the
status thereof as a REMIC under the REMIC Provisions. The Trustee shall not take
any action or cause the Trust 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 (i) endanger the status of any Trust REMIC
as a REMIC or (ii) 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 the Trustee and the NIMS Insurer has received an Opinion of Counsel,
addressed to the Trustee (at the expense of the party seeking to take such
action but in no event at the expense of the Trustee) to the effect that the
contemplated action will not, with respect to any Trust REMIC, endanger such
status or result in the imposition of such a tax, nor shall the Servicer take or
fail to take any action (whether or not authorized hereunder) as to which the
Trustee and the NIMS Insurer 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 Servicer 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 Trust REMIC or the respective assets of each, or
causing any Trust REMIC to take any action, which is not contemplated under the
terms of this Agreement, the Servicer will consult with the Trustee, the NIMS
Insurer or its designee, in writing, with respect to whether such action could
cause an Adverse REMIC Event to occur with respect to any Trust REMIC and the
Servicer shall not take any such action or cause any Trust REMIC to take any
such action as to which the Trustee or the NIMS Insurer has advised it in
writing that an Adverse REMIC Event could occur; provided that the Servicer may
conclusively rely on such writing and shall incur no liability for its action or
failure to act in accordance with such writing. The Trustee or the NIMS Insurer
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. At all
times as may be required by the Code, the Trustee will ensure that substantially
all of the assets of REMIC I will consist of "qualified mortgages" as defined in
Section 860G(a)(3) of the Code and


                                      148
<PAGE>

"permitted investments" as defined in Section 860G(a)(5) of the Code, to the
extent such obligations are within the Trustee's control and not otherwise
inconsistent with the terms of this Agreement.

                  (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 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 10.03 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 Servicer pursuant to Section 10.03
hereof, if such tax arises out of or results from a breach by the Servicer of
any of its obligations under Article III or this Article X, or (iii) against
amounts on deposit in the Distribution Account and shall be paid by withdrawal
therefrom.

                  (h) On or before April 15th of each calendar year, commencing
April 15, 2005, the Trustee shall deliver to each Rating Agency and the NIMS
Insurer an Officer's Certificate of the Trustee stating the Trustee's compliance
with this Article X (without regard to any action taken by any party other than
the Trustee).

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

                  (j) Following the Startup Day, neither the Servicer nor the
Trustee shall accept any contributions of assets to any Trust REMIC other than
in connection with any Qualified Substitute Mortgage Loan delivered in
accordance with Section 2.03 unless it shall have received an Opinion of Counsel
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.

                  (k) Neither the Trustee nor the Servicer shall 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.

                  SECTION 10.02. Prohibited Transactions and Activities.

                  None of the Depositor, the Servicer or the Trustee shall sell,
dispose of or substitute for any of the Mortgage Loans (except in connection
with (i) the foreclosure of a Mortgage 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 Mortgage Loans pursuant to
Article II or III of this Agreement), nor acquire any assets for any Trust REMIC
(other than REO Property acquired in respect of a defaulted Mortgage Loan), nor
sell or dispose of any investments in the Collection


                                      149
<PAGE>

Account or the Distribution Account for gain, nor accept any contributions to
any Trust REMIC after the Closing Date (other than a Qualified Substitute
Mortgage Loan delivered in accordance with Section 2.03), unless it has received
an Opinion of Counsel, addressed to the Trustee and the NIMS Insurer (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) that
such sale, disposition, substitution, acquisition or contribution will not (a)
affect adversely the status of any Trust REMIC as a REMIC or (b) cause any Trust
REMIC to be subject to a tax on "prohibited transactions" or "contributions"
pursuant to the REMIC Provisions.

                  SECTION 10.03. Servicer and Trustee Indemnification.

                  (a) In the event that any Trust REMIC fails to qualify as a
REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as a
result of a prohibited transaction or prohibited contribution under the REMIC
Provisions due to (i) the negligent performance by the Trustee of its duties and
obligations set forth herein or (ii) any state, local or franchise taxes imposed
upon the Trust Fund as a result of the location of the Trustee or any
co-trustee, the Trustee shall indemnify the NIMS Insurer, the Servicer and the
Trust Fund against any and all Losses resulting from such negligence, including,
without limitation, any reasonable attorneys' fees imposed on or incurred as a
result of a breach of the Trustee's or any co-trustee's covenants; provided,
however, that the Trustee shall not be liable for any such Losses attributable
to the action or inaction of the Servicer, the Depositor or the Holder of such
Residual Certificate, as applicable, nor for any such Losses resulting from
misinformation provided by the Holder of such Residual Certificate on which the
Trustee has relied. The foregoing shall not be deemed to limit or restrict the
rights and remedies of the Holder of such Residual Certificate now or hereafter
existing at law or in equity. Notwithstanding the foregoing, however, in no
event shall the Trustee have any liability (1) for any action or omission that
is taken in accordance with and in compliance with the express terms of, or
which is expressly permitted by the terms of, this Agreement, (2) for any Losses
other than arising out of a negligent performance by the Trustee of its duties
and obligations set forth herein, and (3) for any special or consequential
damages to Certificateholders (in addition to payment of principal and interest
on the Certificates).

                  (b) In the event that any Trust REMIC fails to qualify as a
REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as a
result of a prohibited transaction or prohibited contribution under the REMIC
Provisions due to (i) the negligent performance by the Servicer of its duties
and obligations set forth herein or (ii) any state, local or franchise taxes
imposed upon the Trust Fund as a result of the location of the Servicer or any
sub-servicer, the Servicer shall indemnify the NIMS Insurer, the Trustee and the
Trust Fund against any and all losses, claims, damages, liabilities or expenses
("Losses") resulting from such negligence, including, without limitation, any
reasonable attorneys' fees imposed on or incurred as a result of a breach of the
Servicer's or any sub-servicer's covenants; provided, however, that the Servicer
shall not be liable for any such Losses attributable to the action or inaction
of the Trustee, the Depositor or the Holder of such Residual Certificate, as
applicable, nor for any such Losses resulting from misinformation provided by
the Holder of such Residual Certificate on which the Servicer has relied. The
foregoing shall not be deemed to limit or restrict the rights and remedies of
the Holder of such Residual Certificate now or hereafter existing at law or in
equity. Notwithstanding the foregoing, however, in no event shall the Servicer
have any liability (1) for any action or omission that is taken in accordance
with and in compliance with the express terms


                                      150
<PAGE>

of, or which is expressly permitted by the terms of, this Agreement, (2) for any
Losses other than arising out of a negligent performance by the Servicer of its
duties and obligations set forth herein, and (3) for any special or
consequential damages to Certificateholders (in addition to payment of principal
and interest on the Certificates).

                            MISCELLANEOUS PROVISIONS

                  SECTION 11.01. Amendment.

                  This Agreement may be amended from time to time by the
Depositor, the Servicer and the Trustee with the consent of the NIMS Insurer and
without the consent of any of the Certificateholders, (i) to cure any ambiguity
or defect, (ii) to correct, modify or supplement any provisions herein
(including to give effect to the expectations of Certificateholders), or (iii)
to make any other provisions with respect to matters or questions arising under
this Agreement which shall not be inconsistent with the provisions of this
Agreement; provided that such action shall not adversely affect in any material
respect the interests of any Certificateholder as evidenced by either (i) an
Opinion of Counsel delivered to the Servicer, the Trustee and the NIMS Insurer
or (ii) confirmation from the Rating Agencies, delivered to the Servicer, the
Trustee and the NIMS Insurer, that such amendment will not result in the
reduction or withdrawal of the rating of any outstanding Class of Certificates.
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 Servicer, the NIMS Insurer and the Trustee with the consent of
the NIMS Insurer and the Holders of Certificates entitled to at least 66% of the
Voting Rights for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Agreement or of modifying in
any manner the rights of the Holders of Certificates; provided, however, that no
such amendment shall (i) reduce in any manner the amount of, or delay the timing
of, payments received on Mortgage Loans which are required to be distributed on
any Certificate without the consent of the Holder of such Certificate, (ii)
adversely affect in any material respect the interests of the Holders of any
Class of Certificates (as evidenced by either (i) an Opinion of Counsel
delivered to the Trustee and the NIMS Insurer or (ii) confirmation from the
Rating Agencies, delivered to the Servicer, the Trustee and the NIMS Insurer,
that such action will not result in the reduction or withdrawal of the rating of
any outstanding Class of Certificates) in a manner, other than as described in
(i), or (iii) modify the consents required by the immediately preceding clauses
(i) and (ii) without the consent of the Holders of all Certificates then
outstanding. Notwithstanding any other provision of this Agreement, for purposes
of the giving or withholding of consents pursuant to this Section 11.01,
Certificates registered in the name of the Depositor or the Servicer or any
Affiliate thereof shall be entitled to Voting Rights with respect to matters
affecting such Certificates.

                  Notwithstanding any contrary provision of this Agreement,
neither the Trustee nor the NIMS Insurer shall consent to any amendment to this
Agreement unless it shall have first received an Opinion of Counsel satisfactory
to the NIMS Insurer to the effect that such amendment will not result in the
imposition of any tax on any Trust REMIC pursuant to the REMIC Provisions or
cause any Trust REMIC to fail to qualify as a REMIC at any time that any
Certificates are outstanding.

<PAGE>

                  Promptly after the execution of any such amendment the Trustee
shall furnish a copy of such amendment to each Certificateholder and make
available to each Certificateholder and the NIMS Insurer.

                  It shall not be necessary for the consent of
Certificateholders under this Section 11.01 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.

                  The cost of any Opinion of Counsel to be delivered pursuant to
this Section 11.01 shall be borne by the Person seeking the related amendment,
but in no event shall such Opinion of Counsel be an expense of the Trustee.

                  The Trustee may, but shall not be obligated to enter into any
amendment pursuant to this Section that affects its rights, duties and
immunities under this Agreement or otherwise.

                  SECTION 11.02. Recordation of Agreement; Counterparts.

                  To the extent permitted by applicable law, this Agreement 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 Servicer at the expense of the Certificateholders, but only upon
direction of the Trustee accompanied by 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 11.03. Limitation on Rights of Certificateholders.

                  The death or incapacity of any Certificateholder shall not
operate to terminate this Agreement or the Trust, nor entitle such
Certificateholder's legal representatives or heirs to claim an accounting or to
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.

                  No Certificateholder shall have any right to vote (except as
expressly provided for herein) or in any manner otherwise control the operation
and management of the Trust, or the obligations of the parties hereto, nor shall
anything herein set forth, or contained in the terms of any 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 shall have any right by virtue 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 also the
Holders of Certificates entitled to at least 25% of the Voting Rights 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 15 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 is
understood and intended, and 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 whatsoever by virtue 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 equal,
ratable and common benefit of all Certificateholders. For the protection and
enforcement of the provisions of this Section, each and every Certificateholder
and the Trustee shall be entitled to such relief as can be given either at law
or in equity.

                  SECTION 11.04. Governing Law.

it is the express intent of the parties that such conveyance be deemed a pledge
of the Mortgage Loans by the Depositor to the Trustee to secure a debt or other

conveyance provided for in Section 2.01 hereof shall be deemed to be a grant by
the Depositor to the Trustee of a security interest in all of the Depositor's
right, title and interest in and to the Mortgage Loans and all amounts payable
to the holders of the Mortgage 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 Collection Account and the Distribution Account, whether in the form of
cash, instruments, securities or other property; (3) the obligations secured by

under this Agreement, including the obligation to provide to the
Certificateholders the benefits of this Agreement relating to the Mortgage Loans
and the Trust Fund; and (4) notifications to persons holding such property, and
acknowledgments, receipts or confirmations from persons holding such property,

from, financial intermediaries, bailees or agents (as applicable) of the Trustee
for the purpose of perfecting such security interest under applicable law.
Accordingly,


                                      156

of Certificates, but

<PAGE>


the Trustee may require payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any transfer or
exchange of Certificates.

         The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer and the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

         The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all of the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

         The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

         Unless the certificate of authentication hereon has been executed by
the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

designated as Mortgage Pass-Through Certificates of the Series specified on the
face hereof (herein called the "Certificates") and representing a Percentage
Interest in the Class of Certificates specified on the face hereof equal to the
denomination specified on the face hereof divided by the aggregate Certificate
Principal Balance of the Class of Certificates specified on the face hereof.

         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
Distribution Account may be made from time to time for purposes other than

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

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 in the Certificate

denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

         The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified

limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

of Certificates, but


                                     A-2-3
<PAGE>


the Trustee may require payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any transfer or
exchange of Certificates.

         The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

         The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all of the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

         The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

         Unless the certificate of authentication hereon has been executed by
the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

service charge will be made for any such registration of transfer or exchange of
Certificates, but the Trustee may require payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection with any
transfer or exchange of Certificates.

         The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

         The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all of the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

         The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

         Unless the certificate of authentication hereon has been executed by
the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

Agreement to purchase from REMIC I all of the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the

Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

         The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the

notice to the contrary.

         The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts

The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all of the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

endorsed by, or accompanied by an assignment in the form below or other written
instrument of transfer in form satisfactory to the Trustee duly executed by, the

thereupon one or more new Certificates of the same Class in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

         The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

         The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all of the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

         The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

         Unless the certificate of authentication hereon has been executed by
the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

         The Pass-Through Rate applicable to the calculation of interest payable
with respect to this Certificate on any Distribution Date shall equal a rate per

         This Certificate is one of a duly authorized issue of Certificates
designated as Mortgage Pass-Through Certificates of the Series specified on the
face hereof (herein called the "Certificates") and representing a Percentage
Interest in the Class of Certificates specified on the face hereof equal to the
denomination specified on the face hereof divided by the aggregate Certificate
Principal Balance of the Class of Certificates specified on the face hereof.

         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
Distribution Account may be made from time to time for purposes other than
distributions to Certificateholders, such purposes including reimbursement of
advances made, or certain expenses incurred, with respect to the Mortgage Loans.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to at least 66% 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
exchange herefor 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 in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies appointed by the Trustee as provided in the Agreement, duly
endorsed by, or accompanied by an assignment in the form below or other written
instrument of transfer in form satisfactory to the Trustee duly executed by, the
Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of the same Class in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

         No transfer of this Certificate to a Plan subject to ERISA or Section
4975 of the Code, any Person acting, directly or indirectly, on behalf of any

         The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

         The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

         The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all of the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

         The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

         Unless the certificate of authentication hereon has been executed by
the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

loans (the "Mortgage Loans") formed and sold by

                MORTGAGE ASSET SECURITIZATION TRANSACTIONS, INC.

of the Percentage Interest evidenced by this Certificate and the amount required
to be distributed to the Holders of Class M-7 Certificates on such Distribution
Date pursuant to the Agreement.

designated as Mortgage Pass-Through Certificates of the Series specified on the
face hereof (herein called the "Certificates") and representing a Percentage
Interest in the Class of Certificates specified on the face hereof equal to the

Principal Balance of the Class of Certificates specified on the face hereof.

         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
Distribution Account may be made from time to time for purposes other than
distributions to Certificateholders, such purposes including reimbursement of
advances made, or certain expenses incurred, with respect to the Mortgage Loans.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee

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 in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies appointed by the Trustee as provided in the Agreement, duly
endorsed by, or accompanied by an assignment in the form below or other written
instrument of transfer in form satisfactory to the Trustee duly executed by, the
Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of the same Class in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

         No transfer of this Certificate to a Plan subject to ERISA or Section
4975 of the Code, any Person acting, directly or indirectly, on behalf of any

<PAGE>


         The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

         The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

         The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all of the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

         The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

         Unless the certificate of authentication hereon has been executed by
the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all of the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

Depositor and the Trustee assumes no responsibility for their correctness.

         Unless the certificate of authentication hereon has been executed by
the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

         The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the

notice to the contrary.

         The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement

Agreement to purchase from REMIC I all of the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

         The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

         Unless the certificate of authentication hereon has been executed by
the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

<PAGE>


only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose as provided in the Agreement.

         This Certificate is one of a duly authorized issue of Certificates
designated as Mortgage Pass-Through Certificates of the Series specified on the
face hereof (herein called the "Certificates") and representing a Percentage
Interest in the Class of Certificates specified on the face hereof equal to the
denomination specified on the face hereof divided by the aggregate Certificate
Principal Balance of the Class of Certificates specified on the face hereof.

         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
Distribution Account may be made from time to time for purposes other than
distributions to Certificateholders, such purposes including reimbursement of
advances made, or certain expenses incurred, with respect to the Mortgage Loans.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to at least 66% 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
exchange herefor 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 in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies appointed by the Trustee as provided in the Agreement, duly
endorsed by, or accompanied by an assignment in the form below or other written
instrument of transfer in form satisfactory to the Trustee duly executed by, the
Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of the same Class in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

         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 Trustee 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 F-1, 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


                                     A-17-4
<PAGE>


shall not be an expense of the Trust Fund or of the Depositor, the Trustee or
the 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 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 Depositor and the
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 Certificate to a Plan subject to ERISA or Section
4975 of the Code, any Person acting, directly or indirectly, on behalf of any
such Plan or any Person using "Plan Assets" to acquire this Certificate shall be
made except in accordance with Section 5.02(c) of the Agreement.

         The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

         The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

         The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all of the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate principal balance of the Mortgage Loans as of the Cut-off
Date.

         The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

appointed by the Trustee for that purpose as provided in the Agreement.

         This Certificate is one of a duly authorized issue of Certificates
designated as Mortgage Pass-Through Certificates of the Series specified on the
face hereof (herein called the "Certificates") and representing a Percentage
Interest in the Class of Certificates specified on the face hereof equal to the
denomination specified on the face hereof divided by the aggregate Certificate
Principal Balance of the Class of Certificates specified on the face hereof.

         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
Distribution Account may be made from time to time for purposes other than
distributions to Certificateholders, such purposes including reimbursement of
advances made, or certain expenses incurred, with respect to the Mortgage Loans.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to at least 66% 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
exchange herefor 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 in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies appointed by the Trustee as provided in the Agreement, duly
endorsed by, or accompanied by an assignment in the form below or other written
instrument of transfer in form satisfactory to the Trustee duly executed by, the
Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of the same Class in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

         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 Trustee 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 F-1, 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


                                     A-18-4
<PAGE>


shall not be an expense of the Trust Fund or of the Depositor, the Trustee or
the 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 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 Depositor and the
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 Certificate to a Plan subject to ERISA or Section
4975 of the Code, any Person acting, directly or indirectly, on behalf of any
such Plan or any Person using "Plan Assets" to acquire this Certificate shall be
made except in accordance with Section 5.02(c) of the Agreement.

         The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

         The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

         The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all of the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate principal balance of the Mortgage Loans as of the Cut-off
Date.

         The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

         Prior to registration of any transfer, sale or other disposition of
this Certificate, the proposed transferee shall provide to the Trustee (i) an
affidavit to the effect that such transferee is any Person other than a
Disqualified Organization or the agent (including a broker, nominee or
middleman) of a Disqualified Organization, and (ii) a certificate that
acknowledges that (A) the Class R Certificates have been designated as a
residual interest in a REMIC, (B) it will include in its income a pro rata share
of the net income of the Trust Fund and that such income may be an "excess
inclusion," as defined in the Code, that, with certain exceptions, cannot be
offset by other losses or benefits from any tax exemption, and (C) it expects to
have the financial means to satisfy all of its tax obligations including those
relating to holding the Class R Certificates. Notwithstanding the registration
in the Certificate Register of any transfer, sale or other disposition of this
Certificate to a Disqualified Organization or an agent (including a broker,
nominee or middleman) of a Disqualified Organization, such registration shall be
deemed to be of no legal force or effect whatsoever and such Person shall not be
deemed to be a Certificateholder for any purpose, including, but not limited to,
the receipt of distributions in respect of this Certificate.

         The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have consented to the provisions of Section 5.02 of the Agreement and
to any amendment of the Agreement deemed necessary by counsel of the Depositor
to ensure that the transfer of this Certificate to any Person other than a
Permitted Transferee or any other Person will not cause the Trust Fund to cease
to qualify as a REMIC or cause the imposition of a tax upon the REMIC.

         The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

         The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all of the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate principal balance of the Mortgage Loans as of the Cut-off
Date.

         The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

         Unless the certificate of authentication hereon has been executed by
the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

loans (the "Mortgage Loans") formed and sold by

                MORTGAGE ASSET SECURITIZATION TRANSACTIONS, INC.

         MORTGAGE ASSET SECURITIZATION TRANSACTIONS, INC., THE SERVICER, THE
         TRUSTEE OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER THIS CERTIFICATE
         NOR THE UNDERLYING MORTGAGE LOANS ARE GUARANTEED BY ANY AGENCY OR
         INSTRUMENTALITY OF THE UNITED STATES.

         This certifies that UBS Securities LLC is the registered owner of a
Percentage Interest (as specified above) in that certain beneficial ownership
interest evidenced by all the Certificates of the Class to which this
Certificate belongs created pursuant to a Pooling and Servicing Agreement, dated
as specified above (the "Agreement"), among Mortgage Asset Securitization
Transactions, Inc. (hereinafter called the "Depositor," which term includes any
successor entity under the Agreement), the Servicer and the Trustee, a summary
of certain of the pertinent provisions of which is set forth hereafter. To the
extent not defined herein, the capitalized terms used herein have the meanings
assigned 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 the 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 (a "Distribution Date"), commencing on the
First Distribution Date specified above, to the Person in whose name this
Certificate is registered on 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 Class R-X Certificates on such Distribution

the Certificate Register. Notwithstanding the above, the final distribution on
this Certificate will be made after due notice by the Trustee of the pendency of
such distribution and

<PAGE>


only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose as provided in the Agreement.

         This Certificate is one of a duly authorized issue of Certificates
designated as Mortgage Pass-Through Certificates of the Series specified on the
face hereof (herein called the "Certificates") and representing a Percentage
Interest in the Class of Certificates specified on the face hereof.

         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
Distribution Account may be made from time to time for purposes other than
distributions to Certificateholders, such purposes including reimbursement of
advances made, or certain expenses incurred, with respect to the Mortgage Loans.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer and the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to at least 66% 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
exchange herefor 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 in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies appointed by the Trustee as provided in the Agreement, duly
endorsed by, or accompanied by an assignment in the form below or other written
instrument of transfer in form satisfactory to the Trustee duly executed by, the
Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of the same Class in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

         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 Trustee 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 F-1, 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 or
the Servicer in their


                                     A-20-4
<PAGE>


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. Neither the Depositor nor 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 Depositor and the
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 Certificate to a Plan subject to ERISA or Section
4975 of the Code, any Person acting, directly or indirectly, on behalf of any
such Plan or any Person using "Plan Assets" to acquire this Certificate shall be
made except in accordance with Section 5.02(c) of the Agreement.

         The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

         Prior to registration of any transfer, sale or other disposition of
this Certificate, the proposed transferee shall provide to the Trustee (i) an
affidavit to the effect that such transferee is any Person other than a
Disqualified Organization or the agent (including a broker, nominee or
middleman) of a Disqualified Organization, and (ii) a certificate that
acknowledges that (A) the Class R-X Certificates have been designated as a
residual interest in a REMIC, (B) it will include in its income a pro rata share
of the net income of the Trust Fund and that such income may be an "excess
inclusion," as defined in the Code, that, with certain exceptions, cannot be
offset by other losses or benefits from any tax exemption, and (C) it expects to
have the financial means to satisfy all of its tax obligations including those
relating to holding the Class R-X Certificates. Notwithstanding the registration
in the Certificate Register of any transfer, sale or other disposition of this
Certificate to a Disqualified Organization or an agent (including a broker,
nominee or middleman) of a Disqualified Organization, such registration shall be
deemed to be of no legal force or effect whatsoever and such Person shall not be
deemed to be a Certificateholder for any purpose, including, but not limited to,
the receipt of distributions in respect of this Certificate.

         The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have consented to the provisions of Section 5.02 of the Agreement and
to any amendment of the Agreement deemed necessary by counsel of the Depositor
to ensure that the transfer of this Certificate to any Person other than a
Permitted Transferee or any other Person will not cause the Trust Fund to cease
to qualify as a REMIC or cause the imposition of a tax upon the REMIC.

         The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment to the Certificateholders of all
amounts held by the Trustee and required to be paid to them pursuant to the
Agreement following the earlier of (i) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all of the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate principal balance of the Mortgage Loans as of the Cut-off
Date.

         The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

         Unless the certificate of authentication hereon has been executed by
the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

investments of such subsidiaries are managed under the Transferee's direction.

the Transferee for the account of a third party (including any separate account)
in reliance on Rule 144A, the Transferee will only purchase for

buyer" within the meaning of Rule 144A. In addition, the Transferee agrees that

Transferee has obtained a current representation letter from such third party or
taken other appropriate steps contemplated by Rule 144A to conclude that such
third party independently meets the definition of "qualified institutional
buyer" set forth in Rule 144A.

               7.   The Transferee will notify each of the parties to which this
certification is made of any changes in the information and conclusions herein.

provided above, the Transferee agrees that it will furnish to such parties
updated annual financial statements promptly after they become available.

               3.   The term "FAMILY OF INVESTMENT COMPANIES" as used herein
means two or more registered investment companies (or series thereof) that have
the same investment adviser or investment advisers that are affiliated (by

                    FORM OF TRANSFER AFFIDAVIT AND AGREEMENT

STATE OF NEW YORK     )

COUNTY OF NEW YORK    )

               __________________________, being duly sworn, deposes, represents
and warrants as follows:

               1.   I am a ______________________ of
____________________________ (the "Owner") a corporation duly organized and
existing under the laws of ______________, the record owner of MASTR Asset
Backed Securities Trust, Series 2005-NC1, Mortgage Pass-Through Certificates,
Class [R][R-X] Certificates, (the "Residual Certificates"), on behalf of whom I
make this affidavit and agreement. Capitalized terms used but not defined herein
have the respective meanings assigned thereto in the Pooling and Servicing
Agreement pursuant to which the Residual Certificates were issued.

               2.   The Owner (i) is and will be a "Permitted Transferee" as of
____________, 20__ and (ii) is acquiring the Residual Certificates for its own
account or for the account of another Owner from which it has received an
affidavit in substantially the same form as this affidavit. A "Permitted
Transferee" is any person other than a "disqualified organization" or a
possession of the United States. For this purpose, a "disqualified organization"
means the United States, any state or political subdivision thereof, any agency
or instrumentality of any of the foregoing (other than an instrumentality all of
the activities of which are subject to tax and, except for the Federal Home Loan
Mortgage Corporation, a majority of whose board of directors is not selected by
any such governmental entity) or any foreign government, international
organization or any agency or instrumentality of such foreign government or
organization, any rural electric or telephone cooperative, or any organization
(other than certain farmers' cooperatives) that is generally exempt from federal
income tax unless such organization is subject to the tax on unrelated business
taxable income.

               3.   The Owner is aware (i) of the tax that would be imposed on
transfers of the Residual Certificates to disqualified organizations under the
Internal Revenue Code of 1986 that applies to all transfers of the Residual
Certificates after March 31, 1988; (ii) that such tax would be on the transferor
or, if such transfer is through an agent (which person includes a broker,
nominee or middleman) for a non-Permitted Transferee, on the agent; (iii) that
the person otherwise liable for the tax shall be relieved of liability for the
tax if the transferee furnishes to such person an affidavit that the transferee
is a Permitted Transferee and, at the time of transfer, such person does not
have actual knowledge that the affidavit is false; and (iv) that each of the
Residual Certificates may be a "noneconomic residual interest" within the
meaning of proposed Treasury regulations promulgated under the Code and that the
transferor of a "noneconomic residual interest" will remain liable for any taxes
due with respect to the income on such residual interest, unless no significant
purpose of the transfer is to impede the assessment or collection of tax.


                                     F-2-1
<PAGE>


               4.   The Owner is aware of the tax imposed on a "pass-through
entity" holding the Residual Certificates if, at any time during the taxable
year of the pass-through entity, a non-Permitted Transferee is the record holder
of an interest in such entity. (For this purpose, a "pass-through entity"
includes a regulated investment company, a real estate investment trust or
common trust fund, a partnership, trust or estate, and certain cooperatives.)

               5.   The Owner is aware that the Trustee will not register the
transfer of any Residual Certificate unless the transferee, or the transferee's
agent, delivers to the Trustee, among other things, an affidavit in
substantially the same form as this affidavit. The Owner expressly agrees that
it will not consummate any such transfer if it knows or believes that any of the
representations contained in such affidavit and agreement are false.

               6.   The Owner consents to any additional restrictions or
arrangements that shall be deemed necessary upon advice of counsel to constitute
a reasonable arrangement to ensure that the Residual Certificates will only be
owned, directly or indirectly, by an Owner that is a Permitted Transferee.

               7.   The Owner's taxpayer identification number is
_________________.

               8.   The Owner has reviewed the restrictions set forth on the
face of the Residual Certificates and the provisions of Section 5.02(d) of the
Pooling and Servicing Agreement under which the Residual Certificates were
issued (in particular, clauses (iii)(A) and (iii)(B) of Section 5.02(d) which
authorize the Trustee to deliver payments to a person other than the Owner and
negotiate a mandatory sale by the Trustee in the event that the Owner holds such
Certificate in violation of Section 5.02(d)); and that the Owner expressly
agrees to be bound by and to comply with such restrictions and provisions.

               9.   The Owner is not acquiring and will not transfer the
Residual Certificates in order to impede the assessment or collection of any
tax.

               10.  The Owner anticipates that it will, so long as it holds the
Residual Certificates, have sufficient assets to pay any taxes owed by the
holder of such Residual Certificates, and hereby represents to and for the
benefit of the person from whom it acquired the Residual Certificates that the
Owner intends to pay taxes associated with holding such Residual Certificates as
they become due, fully understanding that it may incur tax liabilities in excess
of any cash flows generated by the Residual Certificates.

               11.  The Owner has no present knowledge that it may become
insolvent or subject to a bankruptcy proceeding for so long as it holds the
Residual Certificates.

               12.  The Owner has no present knowledge or expectation that it
will be unable to pay any United States taxes owed by it so long as any of the
Certificates remain outstanding.

               13.  The Owner is not acquiring the Residual Certificates with
the intent to transfer the Residual Certificates to any person or entity that
will not have sufficient assets to pay


                                     F-2-2
<PAGE>


any taxes owed by the holder of such Residual Certificates, or that may become
insolvent or subject to a bankruptcy proceeding, for so long as the Residual
Certificates remain outstanding.

               14.  The Owner will, in connection with any transfer that it
makes of the Residual Certificates, obtain from its transferee the
representations required by Section 5.02(d) of the Pooling and Servicing
Agreement under which the Residual Certificate were issued and will not
consummate any such transfer if it knows, or knows facts that should lead it to
believe, that any such representations are false.

               15.  The Owner will, in connection with any transfer that it
makes of the Residual Certificates, deliver to the Trustee an affidavit, which
represents and warrants that it is not transferring the Residual Certificates to
impede the assessment or collection of any tax and that it has no actual
knowledge that the proposed transferee: (i) has insufficient assets to pay any
taxes owed by such transferee as holder of the Residual Certificates; (ii) may
become insolvent or subject to a bankruptcy proceeding for so long as the
Residual Certificates remains outstanding; and (iii) is not a "Permitted
Transferee".

               16.  The Owner is a citizen or resident of the United States, a
corporation, partnership or other entity created or organized in, or under the
laws of, the United States or any political subdivision thereof, or an estate or
trust whose income from sources without the United States may be included in
gross income for United States federal income tax purposes regardless of its
connection with the conduct of a trade or business within the United States.

               17.  The Owner of the Residual Certificate, hereby agrees that in
the event that the Trust Fund created by the Pooling and Servicing Agreement is
terminated pursuant to Section 9.01 thereof, the undersigned shall assign and
transfer to the Holders of the Class CE Certificates (with respect to a
termination of REMIC I) any amounts in excess of par received in connection with

STATE OF NEW YORK      )

COUNTY OF NEW YORK     )

               __________________________, being duly sworn, deposes, represents
and warrants as follows:

               1.   I am a ____________________ of ____________________________
(the "Owner"), a corporation duly organized and existing under the laws of
______________, on behalf of whom I make this affidavit.

               2.   The Owner is not transferring the Residual Certificates (the
"Residual Certificates") to impede the assessment or collection of any tax.

               3.   The Owner has no actual knowledge that the Person that is
the proposed transferee (the "Purchaser") of the Residual Certificates: (i) has
insufficient assets to pay any taxes owed by such proposed transferee as holder
of the Residual Certificates; (ii) may become insolvent or subject to a
bankruptcy proceeding for so long as the Residual Certificates remain
outstanding; and (iii) is not a Permitted Transferee.

               4.   The Owner understands that the Purchaser has delivered to
the Trustee a transfer affidavit and agreement in the form attached to the
Pooling and Servicing Agreement as Exhibit F-2. The Owner does not know or
believe that any representation contained therein is false.

               5.   At the time of transfer, the Owner has conducted a
reasonable investigation of the financial condition of the Purchaser as
contemplated by Treasury Regulations Section 1.860E-1(c)(4)(i) and, as a result
of that investigation, the Owner has determined that the Purchaser has
historically paid its debts as they became due and has found no significant
evidence to indicate that the Purchaser will not continue to pay its debts as
they become due in the future. The Owner understands that the transfer of a
Residual Certificate may not be respected for United States income tax purposes
(and the Owner may continue to be liable for United States income taxes
associated therewith) unless the Owner has conducted such an investigation.

               6.   Capitalized terms not otherwise defined herein shall have
the meanings ascribed to them in the Pooling and Servicing Agreement.

               2.   Based on my knowledge, the information in these reports,
taken as a whole, does not contain any untrue statement of a material fact or
omit to state a material fact necessary to make the statements made, in light of
the circumstances under which such statements were made, not misleading, as of
the last day of the period covered by this annual report;

statement included in the report and required to be delivered to the Trustee in
accordance with the terms of the Pooling and Servicing Agreement, and except as
disclosed in the reports, the Servicer has fulfilled its obligations under the
servicing agreement; and

               5.   The reports disclose all significant deficiencies relating
to the servicer's compliance with the minimum servicing standards based upon the
report provided by an independent public accountant, after conducting a review
