            ASSET BACKED FUNDING CORPORATION, as depositor (the "Depositor"),
[________________________], as servicer (the "Servicer"), and WELLS FARGO BANK,
N.A., as trustee (the "Trustee") are entering into this Pooling and Servicing
Agreement, dated as of [__________] 1, 20 (the "Agreement").

                            PRELIMINARY STATEMENT

            The Depositor intends to sell pass-through certificates
(collectively, the "Certificates"), to be issued hereunder in multiple Classes,
which in the aggregate will evidence the entire beneficial ownership interest in
the Trust Fund created hereunder. The Certificates will consist of fifteen
Classes of Certificates, designated as (i) the Class A-1, Class A-2, Class A-3
and Class A-4 Certificates, (ii) the Class M-1, Class M-2, Class M-3, Class M-4,
Class M-5, Class M-6 and Class M-7 Certificates, (iii) the Class CE
Certificates, (iv) the Class P Certificates and (v) the Class R and Class R-X
Certificates.

                                     REMIC 1

            As provided herein, the Trustee will make an election to treat the
segregated pool of assets consisting of the Mortgage Loans and certain other
related assets subject to this Agreement (but exclusive of the Yield Maintenance
Agreements, the Reserve Accounts, the Cap Carryover Amounts, the Prepayment
Charges, the Originator Prepayment Charge Payment Amounts and the Servicer
Prepayment Charge Payment Amounts) as a real estate investment conduit (a
"REMIC") for federal income tax purposes, and such segregated pool of assets
will be designated as "REMIC 1." The Class R-1 Interest will represent the sole
class of "residual interests" in REMIC 1 for purposes of the REMIC Provisions
under federal income tax law. The following table irrevocably sets forth the
designation, the Uncertificated REMIC 1 Pass-Through Rate, the initial
Uncertificated Principal Balance, and solely for purposes of satisfying Treasury
Regulations Section 1.860G-1(a)(4)(iii), the "latest possible maturity date" for
each of the REMIC 1 Regular Interests. None of the REMIC 1 Regular Interests
will be certificated.

            As provided herein, the Trustee shall make an election to treat the
segregated pool of assets consisting of the REMIC 1 Regular Interests as a REMIC
for federal income tax purposes, and such segregated pool of assets will be

                                   ARTICLE II

                          CONVEYANCE OF MORTGAGE LOANS;
                        ORIGINAL ISSUANCE OF CERTIFICATES

            Section 2.01 Conveyance of Mortgage Loans.

            The Depositor, concurrently with the execution and delivery hereof,
does hereby transfer, assign, set over and otherwise convey to the Trustee, on
behalf of the Trust, without recourse for the benefit of the Certificateholders
all the right, title and interest of the Depositor, including any security
interest therein for the benefit of the Depositor, in and to (i) each Mortgage
Loan identified on the Mortgage Loan Schedules, including the related Cut-off
Date Principal Balance, all interest accruing thereon after the Cut-off Date and
all collections in respect of interest and principal due after the Cut-off Date;
(ii) property which secured each such Mortgage Loan and which has been acquired
by foreclosure or deed in lieu of foreclosure; (iii) its interest in any
insurance policies in respect of the Mortgage Loans; (iv) all other assets
included or to be included in the Trust Fund; (v) all proceeds of any of the
foregoing; (vi) the rights of the Depositor under the Consulting Agreement; and
(vii) the rights of the Depositor under the Originator Mortgage Loan Purchase
Agreement and the Mortgage Loan Purchase Agreement. Such assignment includes all
interest and principal due to the Depositor or the Servicer after the Cut-off
Date with respect to the Mortgage Loans.

            In connection with such transfer and assignment, the Depositor does
hereby deliver to, and deposit with the Trustee, or its designated agent, the
following documents or instruments with respect to each Mortgage Loan (a
"Mortgage File") so transferred and assigned:

      (i) the original Mortgage Note, endorsed in blank or with respect to any
lost Mortgage Note, an original Lost Note Affidavit, together with a copy of the
related Mortgage Note;

      (ii) the original Mortgage 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 or, if such Mortgage or
power of attorney has been submitted for recording but has not been returned
from the applicable public recording office, has been lost or is not otherwise
available, a copy of such Mortgage or power of attorney, as the case may be,
certified to be a true and complete copy of the original submitted for
recording;

      (iii) an original Assignment of Mortgage, in form and substance acceptable
for recording. The Mortgage shall be assigned in blank;

      (iv) an original copy of any intervening assignment of Mortgage showing a
complete chain of assignments;

      (v) the original or a certified copy of lender's title insurance policy;
and

      (vi) the original or copies of each assumption, modification, written
assurance or substitution agreement, if any.

            The Trustee agrees to execute and deliver to the Depositor 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
F-3 hereto.

            If any of the documents referred to in Section 2.01(ii), (iii) or
(iv) above has as of the Closing Date been submitted for recording but either
(x) has not been returned from the applicable public recording office or (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 no later than the
Closing Date, of a copy of each such document certified by the Seller 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 Seller, delivery to 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. The Depositor shall deliver or cause to be
delivered to the Trustee promptly upon receipt thereof any other 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.

            Upon discovery or receipt of notice of any materially defective
document in, or that a document is missing from, a Mortgage File, the Seller
shall have 120 days to cure such defect or 150 days following the Closing Date,
in the case of missing Mortgages or Assignments or deliver such missing document
to the Trustee. If the Seller does not cure such defect or deliver such missing
document within such time period, the Seller shall either repurchase or
substitute for such Mortgage Loan in accordance with Section 2.03.

            The Depositor herewith delivers to the Trustee executed copies of
the Originator Mortgage Loan Purchase Agreement and the Mortgage Loan Purchase
Agreement.

            Concurrently with the execution and delivery of this Agreement, the
Depositor shall deliver the Mortgage Loan Schedules to the Trustee and the
Servicer. The Depositor and the Trustee shall provide a copy of the Mortgage
Loan Schedules to any Certificateholder upon written request made to either of
them at the addresses set forth on Exhibits D-1 and D-2, as the same may be
amended from time to time by written notice from such party to the other parties
hereto.

            It is agreed and understood by the parties hereto that it is not
intended that any mortgage loan be included in the Trust that is a "High-Cost
Home Loan" as defined in any of (i) the New Jersey Home Ownership Act effective
November 27, 2003, (ii) the New Mexico Home Loan Protection Act, effective
January 1, 2004, (iii) the Massachusetts Predatory Home Loan Practices Act,
effective November 7, 2004 or (iv) the Indiana Home Loan Practices Act,
effective January 1, 2005.

            Section 2.02 Acceptance by Trustee.

            The Trustee acknowledges the receipt of, subject to the provisions
of Section 2.01 and subject to the review described below and any exceptions
noted on the exception report described in the next paragraph below, the
documents referred to in Section 2.01 above and all other assets included in the
definition of "Trust Fund" 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 "Trust Fund" in trust for the exclusive use and benefit of all
present and future Certificateholders.

            The Trustee agrees, for the benefit of the Certificateholders, to
review each Mortgage File within 60 days after the Closing Date (or, with
respect to any document delivered after the Startup Day, within 60 days of
receipt and with respect to any Qualified Substitute Mortgage, within 60 days
after the assignment thereof) and to certify in substantially the form attached
hereto as Exhibit F-1 that, as to each Mortgage Loan listed in the Mortgage Loan
Schedules (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 required to be delivered to it
pursuant to Section 2.01 of this Agreement are in its possession, (ii) such
documents have been reviewed by it and have not been mutilated, damaged or torn
and relate to such Mortgage Loan and (iii) based on its examination and only as
to the foregoing, the information set forth in the Mortgage Loan Schedules that
corresponds to items (1), (2), (3), (10) and (22) of the Mortgage Loan Schedules
accurately reflects information set forth in the Mortgage File. It is herein
acknowledged that, in conducting such review, the Trustee is under no duty or
obligation to inspect, review or examine any such documents, instruments,
certificates or other papers to determine that they are genuine, enforceable, or
appropriate for the represented purpose or that they have actually been recorded
or that they are other than what they purport to be on their face.

            Prior to the first anniversary date of this Agreement the Trustee
shall deliver to the Depositor, the Servicer and the NIMS Insurer a final
certification in the form annexed hereto as Exhibit F-2 evidencing the
completeness of the Mortgage Files, with any applicable exceptions noted
thereon.

            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
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 shall so notify the Seller, the Depositor, the NIMS Insurer and the
Servicer. In addition, upon the discovery by the Originator, the Seller, the
Depositor, the NIMS Insurer, the Trustee or the Servicer (or upon receipt by the
Trustee of written notification of such breach) of a breach of any of the
representations and warranties made by the Originator in the Originator Mortgage
Loan Purchase Agreement 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 Depositor and the Trustee intend that the assignment and
transfer herein contemplated constitute a sale of the Mortgage Loans and the
Related Documents, conveying good title thereto free and clear of any liens and
encumbrances, from the Depositor to the Trustee 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, on behalf
of the Trust, a first priority perfected security interest in all of the
Depositor's right, title and interest in and to the Mortgage Loans and the
Related Documents, and that this Agreement shall constitute a security agreement
under applicable law.

            The Trustee is hereby directed to execute and deliver, on behalf of
the Trust, the Class A-1 Yield Maintenance Agreement, Group 2-A Yield
Maintenance Agreement and Class M Yield Maintenance Agreement.

            Section 2.03 Repurchase or Substitution of Mortgage Loans by the
Originator or the Seller.

            (a) Upon discovery or receipt of written notice of any materially
defective document in, or that a document is missing from, a Mortgage File or of
the breach by the Originator or the Seller of any representation or warranty
under the Originator Mortgage Loan Purchase Agreement or the Mortgage Loan
Purchase Agreement, as applicable, in respect of any Mortgage Loan which
materially adversely affects the value of such Mortgage Loan, Prepayment Charge
or the interest therein of the Certificateholders, the Trustee shall promptly
notify the Originator or the Seller, as the case may be, the Servicer and the
NIMS Insurer of such defect, missing document or breach and request that, in the
case of a defective or missing document, the Seller cure such defect or deliver
such missing document within 120 days from the date the Seller was notified of
such missing document or defect or, in the case of a beach of a representation
or warranty, request the Originator or the Seller, as applicable, cure such
breach within 90 days from the date the Originator or the Seller, as the case
may be, was notified of such breach. If the Seller does not deliver such missing
document or cure such defect or if the Originator or the Seller, as applicable,
does not cure such breach in all material respects during such period, the
Trustee shall enforce the Originator's or the Seller's obligation, as the case
may be, under the Originator Mortgage Loan Purchase Agreement or the Mortgage
Loan Purchase Agreement, as applicable, and cause the Originator or the Seller,
as applicable, to repurchase such Mortgage Loan from the Trust Fund at the
Purchase Price on or prior to the Determination Date following the expiration of
such period (subject to Section 2.03(d)). The Purchase Price for the repurchased
Mortgage Loan shall be deposited in the Collection Account, and the Trustee,
upon receipt of written notice from the Servicer of such deposit, shall release
to the Originator or the Seller, as applicable, the related Mortgage File and
shall execute and deliver such instruments of transfer or assignment, in each
case without recourse, as the Originator or the Seller, as applicable, shall
furnish to it and as shall be necessary to vest in the Originator or the Seller,
as the case may be, any Mortgage Loan released pursuant hereto and the Trustee
shall have no further responsibility with regard to such Mortgage File. In lieu
of repurchasing any such Mortgage Loan as provided above, the Originator or the
Seller, as the case may be, may cause such Mortgage Loan to be removed from the
Trust Fund (in which case it shall become a Defective Mortgage Loan) and
substitute one or more Eligible Substitute Mortgage Loans in the manner and
subject to the limitations set forth in Section 2.03(c).

            With respect to the representations and warranties set forth in the
Originator Mortgage Loan Purchase Agreement and the Mortgage Loan Purchase
Agreement that are made to the best of the Originator's or the Seller's
knowledge, as applicable, or as to which the Originator or the Seller, as the
case may be, has no knowledge, if it is discovered by the Depositor, the
Servicer, the NIMS Insurer or the Trustee that the substance of such
representation and warranty is inaccurate and such inaccuracy materially and
adversely affects the value of the related Mortgage Loan, Prepayment Charge or
the interest therein of the Certificateholders then, notwithstanding the
Originator's or the Seller's lack of knowledge with respect to the substance of
such representation and warranty being inaccurate at the time the representation
or warranty was made, such inaccuracy shall be deemed a breach of the applicable
representation or warranty.

            It is understood and agreed that the representations and warranties
set forth in the Originator Mortgage Loan Purchase Agreement and the Mortgage
Loan Purchase Agreement shall survive delivery of the Mortgage Files to the
Trustee and the Closing Date and shall inure to the benefit of the
Certificateholders notwithstanding any restrictive or qualified endorsement or
assignment. It is understood and agreed that the obligations of the Originator
and the Seller set forth in this Section 2.03(a) to cure, substitute for or
repurchase a Mortgage Loan pursuant to the Originator Mortgage Loan Purchase
Agreement or the Mortgage Loan Purchase Agreement, as applicable, and to pay the
Reimbursement Amount constitute the sole remedies available to the
Certificateholders and to the Trustee on their behalf respecting a breach of the
representations and warranties contained in the Mortgage Loan Purchase
Agreement.

            The representations and warranties of the Originator with respect to
the Mortgage Loans in the Originator Mortgage Loan Purchase Agreement, which
have been assigned to the Trustee hereunder, were made as of the dates specified
in the Originator Mortgage Loan Purchase Agreement. To the extent that any fact,
condition or event with respect to a Mortgage Loan constitutes a breach of both
(i) a representation or warranty of the Originator under the Originator Mortgage
Loan Purchase Agreement and (ii) a representation or warranty of the Seller
under the Mortgage Loan Purchase Agreement (other than Seller's representations
with respect to predatory and abusive lending laws in Section [____] and [____]
of the Mortgage Loan Purchase Agreement), the only right or remedy of the
Trustee or of any Certificateholder shall be the Trustee's right to enforce the
obligations of the Originator under any applicable representation or warranty
made by it. The Trustee acknowledges that the Seller shall have no obligation or
liability with respect to any breach of a representation or warranty made by it
with respect to the Mortgage Loans (except as otherwise set forth in this
paragraph) if the fact, condition or event constituting such breach also
constitutes a breach of a representation or warranty made by the Originator in
the Originator Mortgage Loan Purchase Agreement, without regard to whether the
Originator fulfills its contractual obligations in respect of such
representation or warranty. In addition, to the extent that any fact, condition
or event with respect to a Mortgage Loan constitutes a breach of both (x) the
Originator's representation with respect to predatory and abusive lending laws
in Section [____] or [____] of the Originator Mortgage Loan Purchase Agreement
and (y) the Seller's representation with respect to predatory and abusive
lending laws in Section [____] or [____] of the Mortgage Loan Purchase
Agreement, the Originator shall be obligated to pay the Reimbursement Amount
relating to such Mortgage Loan, and, to the extent the Originator fails to do
so, the Trustee shall be entitled to enforce the Seller's obligation to pay such
Reimbursement Amount. In any event, the Reimbursement Amount shall be delivered
to the Servicer for deposit into the Collection Account within 10 days from the
date the Seller was notified by the Trustee of the Reimbursement Amount.

            (b) Within 90 days of the earlier of discovery by the Servicer or
receipt of notice by the Servicer of the breach of any representation, warranty
or covenant of the Servicer set forth in Section 2.05 which materially and
adversely affects the interests of the Certificateholders in any Mortgage Loan,
the Servicer shall cure such breach in all material respects.

            (c) Any substitution of Eligible Substitute Mortgage Loans for
Defective Mortgage Loans made pursuant to Section 2.03(a) must be effected prior
to the last Business Day that is within two years after the Closing Date. As to
any Defective Mortgage Loan for which the Originator or the Seller substitutes
an Eligible Substitute Mortgage Loan or Loans, such substitution shall be
effected by the Originator or the Seller, as applicable, delivering to the
Trustee for such Eligible Substitute Mortgage Loan or Loans, the Mortgage Note,
the Mortgage, the Assignment to the Trustee, and such other documents and
agreements, with all necessary endorsements thereon, as are required by Section
2.01, together with an Officers' Certificate providing that each such Eligible
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 shall acknowledge receipt for such Eligible
Substitute Mortgage Loan or Loans and, within ten Business Days thereafter,
shall review such documents as specified in Section 2.02 and deliver to the
Servicer and the NIMS Insurer, with respect to such Eligible Substitute Mortgage
Loan or Loans, a certification substantially in the form attached hereto as
Exhibit F-1, with any applicable exceptions noted thereon. Within one year of
the date of substitution, the Trustee shall deliver to the Servicer and the NIMS
Insurer a certification substantially in the form of Exhibit F-2 hereto with
respect to such Eligible Substitute Mortgage Loan or Loans, with any applicable
exceptions noted thereon. Monthly Payments due with respect to Eligible
Substitute Mortgage Loans in the month of substitution are not part of the Trust
Fund and will be retained by the Originator or the Seller, as applicable. For
the month of substitution, distributions to Certificateholders will reflect the
collections and recoveries in respect of such Defective Mortgage Loan in the
Collection Period or Prepayment Period, as applicable, preceding the date of
substitution and the Depositor, the Originator or the Seller, as the case may
be, shall thereafter be entitled to retain all amounts subsequently received in
respect of such Defective 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 applicable Mortgage Loan Schedule
to reflect the removal of such Defective Mortgage Loan from the terms of this
Agreement and the substitution of the Eligible Substitute Mortgage Loan or Loans
and shall deliver a copy of such amended Mortgage Loan Schedule to the Trustee
and the NIMS Insurer. Upon such substitution, such Eligible 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, in the case of a substitution
effected by the Originator or the Seller, the Originator Mortgage Loan Purchase
Agreement or the Mortgage Loan Purchase Agreement, as the case may be,
including, in the case of a substitution effected by the Originator or the
Seller, all applicable representations and warranties thereof included in the
Originator Mortgage Loan Purchase Agreement or the Mortgage Loan Purchase
Agreement, as the case may be, as of the date of substitution.

            For any month in which the Originator or the Seller substitutes one
or more Eligible Substitute Mortgage Loans for one or more Defective Mortgage
Loans, the Servicer will determine the amount (the "Substitution Adjustment
Amount"), if any, by which the aggregate Purchase Price of all such Defective
Mortgage Loans exceeds the aggregate, as to each such Eligible Substitute
Mortgage Loan, of the principal balance thereof as of the date of substitution,
together with one month's interest on such principal balance at the applicable
Net Mortgage Interest Rate. On the date of such substitution, the Originator or
the Seller, as the case may be, 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, upon receipt of the
related Eligible Substitute Mortgage Loan or Loans and notice by the Servicer of
such deposit, shall release to the Originator or the Seller, as applicable, the
related Mortgage File or Files and shall execute and deliver such instruments of
transfer or assignment, in each case without recourse, as the Originator or the
Seller, as the case may be, shall deliver to it and as shall be necessary to
vest therein any Defective Mortgage Loan released pursuant hereto.

            In addition, the Originator 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 the Trust Fund, including without limitation, any
federal tax imposed on "prohibited transactions" under Section 860F(a)(l) of the
Code or on "contributions after the startup date" under Section 860G(d)(l) of
the Code, or (b) any REMIC to fail to qualify as a REMIC at any time that any
Certificate is outstanding. If such Opinion of Counsel can not be delivered,
then such substitution may only be effected at such time as the required Opinion
of Counsel can be given.

            (d) Upon discovery by the Originator, the Seller, the Servicer, the
NIMS Insurer or the Trustee that any Mortgage Loan does not constitute a
"qualified mortgage" within the meaning of Section 860G(a)(3) of the Code, the
party discovering such fact shall within two Business Days give written notice
thereof to the other parties. In connection therewith, the Originator or the
Seller, as applicable, shall repurchase or, subject to the limitations set forth
in Section 2.03(c), substitute one or more Eligible 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. In addition,
upon discovery that a Mortgage Loan is defective in a manner that would cause it
to be a "defective obligation" within the meaning of Treasury Regulations
relating to REMICs, the Originator or the Seller, as the case may be, shall cure
the defect or make the required purchase or substitution no later than 90 days
after the discovery of the defect. Any such repurchase or substitution shall be
made in the same manner as set forth in Section 2.03(a). The Trustee shall
reconvey to the Originator or the Seller, as applicable, 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 and the NIMS Insurer that as of the Closing Date or as of such
date specifically provided herein:

            (i) The Servicer is a corporation duly organized, validly existing
      and in good standing under the laws of [_________] and has all licenses
      necessary to carry on its business as now being conducted, except for such
      licenses, certificates and permits the absence of which, individually or
      in the aggregate, would not have a material adverse effect on the ability
      of the Servicer to conduct its business as it is presently conducted, and
      is licensed, qualified and in good standing in the states where the
      Mortgaged Property is located if the laws of such state require licensing
      or qualification in order to conduct business of the type conducted by the
      Servicer or to ensure the enforceability or validity of each Mortgage
      Loan; the Servicer has the power and authority to execute and deliver this
      Agreement and to perform in accordance herewith; the execution, delivery
      and performance of this Agreement (including all instruments of transfer
      to be delivered pursuant to this Agreement) by the Servicer and the
      consummation of the transactions contemplated hereby have been duly and
      validly authorized; and all requisite corporate action has been taken by
      the Servicer to make this Agreement valid and binding upon the Servicer in
      accordance with its terms;

            (ii) The consummation of the transactions contemplated by this
      Agreement are in the ordinary course of business of the Servicer and will
      not result in the breach of any term or provision of the articles of
      incorporation or by-laws of the Servicer or result in the breach of any
      term or provision of, or conflict with or constitute a default under or
      result in the acceleration of any obligation under, any agreement,
      indenture or loan or credit agreement or other instrument to which the
      Servicer or its property is subject, or result in the violation of any
      law, rule, regulation, order, judgment or decree to which the Servicer or
      its property is subject;

            (iii) The Servicer is an approved seller/servicer of conventional
      residential mortgage loans for Fannie Mae or Freddie Mac, with the
      facilities, procedures, and experienced personnel necessary for the sound
      servicing of mortgage loans of the same type as the Mortgage Loans. The
      Servicer is a HUD approved mortgagee pursuant to Section 203 of the
      National Housing Act and is in good standing to sell mortgage loans to and
      service mortgage loans for Fannie Mae or Freddie Mac, and no event has
      occurred, including but not limited to a change in insurance coverage,
      which would make the Servicer unable to comply with Fannie Mae or Freddie
      Mac eligibility requirements or which would require notification to either
      Fannie Mae or Freddie Mac;

            (iv) This Agreement, and all documents and instruments contemplated
      hereby which are executed and delivered by the Servicer, constitute and
      will constitute valid, legal and binding obligations of the Servicer,
      enforceable in accordance with their respective terms, except as the
      enforcement thereof may be limited by applicable bankruptcy, insolvency,
      reorganization, moratorium or other similar laws affecting the enforcement
      of creditors' rights generally (whether considered in a proceeding at law
      or in equity);

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

            (vi) There is no action, suit, proceeding or investigation pending
      or, to its knowledge, threatened against the Servicer that, either
      individually or in the aggregate, may result in any material adverse
      change in the business, operations, financial condition, properties or
      assets of the Servicer, or in any material impairment of the right or
      ability of the Servicer to carry on its business substantially as now
      conducted, or in any material liability on the part of the Servicer, or
      that would draw into question the validity or enforceability of this
      Agreement or of any action taken or to be taken in connection with the
      obligations of the Servicer contemplated herein, or that would be likely
      to impair materially the ability of the Servicer to perform under the
      terms of this Agreement;

            (vii) No consent, approval 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 of the transactions contemplated by this Agreement, except
      for such consents, approvals, authorizations and orders, if any, that have
      been obtained; and

            (viii) No information in this Agreement provided by the Servicer nor
      any 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 or will contain any untrue
      statement of a material fact or omits or will omit 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.

            (ix) The Servicer has fully furnished, and shall continue to fully
      furnish for so long as it is servicing the Mortgage Loans hereunder, in
      accordance with the Fair Credit Reporting Act and its implementing
      regulations, accurate and complete information on the Mortgagor credit
      files to Equifax, Experian and Trans Union Credit Information Company on a
      monthly basis.

            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 and shall inure to the benefit of the Trustee, the
Depositor, the NIMS Insurer 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, Prepayment Charge 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 other parties hereto.

            Section 2.06 Representations and Warranties of the Depositor.

            The Depositor represents and warrants to the Trust and the Trustee
on behalf of the Certificateholders and to the Servicer and the NIMS Insurer as
follows:

            (i) This agreement constitutes a legal, valid and binding obligation
      of the Depositor, enforceable against the Depositor in accordance with its
      terms, except as enforceability may be limited by applicable bankruptcy,
      insolvency, reorganization, moratorium or other similar laws now or
      hereafter in effect affecting the enforcement of creditors' rights in
      general and except as such enforceability may be limited by general
      principles of equity (whether considered in a proceeding at law or in
      equity);

            (ii) Immediately prior to the sale and assignment by the Depositor
      to the Trustee on behalf of the Trust of each Mortgage Loan, the Depositor
      had good and marketable title to each Mortgage Loan (insofar as such title
      was conveyed to it by the Seller) subject to no prior lien, claim,
      participation interest, mortgage, security interest, pledge, charge or
      other encumbrance or other interest of any nature;

            (iii) As of the Closing Date, the Depositor has transferred all
      right, title interest in the Mortgage Loans to the Trustee on behalf of
      the Trust;

            (iv) The Depositor has not transferred the Mortgage Loans to the
      Trustee on behalf of the Trust with any intent to hinder, delay or defraud
      any of its creditors;

            (v) The Depositor has been duly incorporated and is validly existing
      as a corporation in good standing under the laws of the State of Delaware,
      with full corporate power and authority to own its assets and conduct its
      business as presently being conducted;

            (vi) The Depositor is not in violation of its certificate of
      incorporation or by-laws or in default in the performance or observance of
      any material obligation, agreement, covenant or condition contained in any
      contract, indenture, mortgage, loan agreement, note, lease or other
      instrument to which the Depositor is a party or by which it or its
      properties may be bound, which default might result in any material
      adverse changes in the financial condition, earnings, affairs or business
      of the Depositor or which might materially and adversely affect the
      properties or assets, taken as a whole, of the Depositor;

            (vii) The execution, delivery and performance of this Agreement by
      the Depositor, and the consummation of the transactions contemplated
      thereby, do not and will not result in a material breach or violation of
      any of the terms or provisions of, or, to the knowledge of the Depositor,
      constitute a default under, any indenture, mortgage, deed of trust, loan
      agreement or other agreement or instrument to which the Depositor is a
      party or by which the Depositor is bound or to which any of the property
      or assets of the Depositor is subject, nor will such actions result in any
      violation of the provisions of the certificate of incorporation or by-laws
      of the Depositor or, to the best of the Depositor's knowledge without
      independent investigation, any statute or any order, rule or regulation of
      any court or governmental agency or body having jurisdiction over the
      Depositor or any of its properties or assets (except for such conflicts,
      breaches, violations and defaults as would not have a material adverse
      effect on the ability of the Depositor to perform its obligations under
      this Agreement);

            (viii) To the best of the Depositor's knowledge without any
      independent investigation, no consent, approval, authorization, order,
      registration or qualification of or with any court or governmental agency
      or body of the United States or any other jurisdiction is required for the
      issuance of the Certificates, or the consummation by the Depositor of the
      other transactions contemplated by this Agreement, except such consents,
      approvals, authorizations, registrations or qualifications as (a) may be
      required under State securities or Blue Sky laws, (b) have been previously
      obtained or (c) the failure of which to obtain would not have a material
      adverse effect on the performance by the Depositor of its obligations
      under, or the validity or enforceability of, this Agreement; and

            (ix) There are no actions, proceedings or investigations pending
      before or, to the Depositor's knowledge, threatened by any court,
      administrative agency or other tribunal to which the Depositor is a party
      or of which any of its properties is the subject: (a) which if determined
      adversely to the Depositor would have a material adverse effect on the
      business, results of operations or financial condition of the Depositor;
      (b) asserting the invalidity of this Agreement or the Certificates; (c)
      seeking to prevent the issuance of the Certificates or the consummation by
      the Depositor of any of the transactions contemplated by this Agreement,
      as the case may be; (d) which might materially and adversely affect the
      performance by the Depositor of its obligations under, or the validity or
      enforceability of, this Agreement.

            Section 2.07 Issuance of Certificates and the Uncertificated Regular
Interests.

            The Trustee acknowledges the assignment to it of the Mortgage Loans
and the delivery to it of the Mortgage Files, subject to the provisions of
Sections 2.01 and 2.02, and the Trustee acknowledges the assignment to it of all
other assets included in the Trust Fund, receipt of which is hereby
acknowledged. Concurrently with such assignment and delivery and in exchange
therefor, the Trustee, pursuant to the Written Order to Authenticate executed by
an officer of the Depositor, has executed, and the Certificate Registrar has
authenticated and delivered to or upon the order of the Depositor, the
Certificates (other than the Class CE, Class P, Class R and Class R-X
Certificates) in minimum dollar denominations or $25,000 and integral dollar
multiples of $1 in excess. The Class CE and Class P Certificates are issuable
only in minimum Percentage Interests of 10%. The Class R and Class R-X
Certificates are each issuable only as a single certificate. The Trustee
acknowledges the issuance of the uncertificated REMIC 1 Regular Interests and
declares that it hold such regular interests as assets of REMIC 2. The Trustee
acknowledges the obligation of the Class CE Certificates to pay Cap Carryover
Amounts, and declares that it hold the same as assets of the Grantor Trust on
behalf of the Holders of the Class A-1, Class A-2, Class A-3, Class A-4, Class
M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6 and Class M-7
Certificates, respectively, which shall be treated as beneficially owning the
right to receive the Cap Carryover Amounts from the Grantor Trust. In addition
to the assets described in the preceding sentence, the assets of the Grantor
Trust shall also include (i) Prepayment Charges, any Originator Prepayment
Charge Payment Amounts, any Servicer Prepayment Charge Payment Amounts and the
beneficial interest of the Class P Certificates with respect thereto and (ii)
the Yield Maintenance Agreements, the Reserve Accounts and the beneficial
interest of the Class CE Certificates with respect thereto, subject to the
obligation to pay Cap Carryover Amounts. The interests evidenced by the
Certificates constitute the entire beneficial ownership interest in the Trust
Fund.

                                  ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF THE TRUST FUND

            Section 3.01 Servicer to Act as Servicer.

            The Servicer, as independent contract servicer, shall service and
administer the Mortgage Loans in accordance with this Agreement and the normal
and usual standards of practice of prudent mortgage servicers servicing similar
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, and shall have full power and authority, acting alone, to do or cause
to be done any and all things in connection with such servicing and
administration which the Servicer may deem necessary or desirable and consistent
with the terms of this Agreement (the "Servicing Standard").

            Consistent with the terms of this Agreement, the Servicer may waive,
modify or vary any term of any Mortgage Loan or consent to the postponement of
strict compliance with any such term or in any manner grant indulgence to any
Mortgagor if in the Servicer's reasonable and prudent determination such waiver,
modification, postponement or indulgence is not materially adverse to the
Certificateholders; provided, however, that the Servicer shall not make future
advances and, except as set forth in the following sentence or Section 3.03, the
Servicer shall not permit any modification with respect to any Mortgage Loan
that would (i) change the Mortgage Interest Rate, defer or forgive the payment
thereof of any principal or interest payments, reduce the outstanding principal
amount (except for actual payments of principal) or extend the final maturity
date with respect to such Mortgage Loan, (ii) affect adversely the status of any
REMIC constituting part of the Trust Fund as a REMIC or (iii) cause any such
REMIC to be subject to a tax on "prohibited transactions" or "contributions"
pursuant to the REMIC Provisions. In the event that the Mortgagor is in default
with respect to the Mortgage Loan or such default is, in the judgment of the
Servicer, reasonably foreseeable, the Servicer may permit a modification of such
Mortgage Loan to reduce the Principal Balance thereof and/or extend the term,
but not beyond the latest maturity date of any other Mortgage Loan.
Notwithstanding the foregoing, the Servicer shall not permit any modification
with respect to any Mortgage Loan that would both (x) effect an exchange or
reissuance of such Mortgage Loan under Section 1.860G-2(b) of the Treasury
Regulations and (y) cause any REMIC constituting part of the Trust Fund to fail
to qualify as a REMIC under the Code or the imposition of any tax on "prohibited
transactions" or "contributions" after the Startup Day under the REMIC
Provisions. 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. Without limiting the generality
of the foregoing, the Servicer shall continue, and is hereby authorized and
empowered to execute and deliver on behalf of itself, and the Trustee, all
instruments of satisfaction or cancellation, or of partial or full release,
discharge and all other comparable instruments, with respect to the Mortgage
Loans and with respect to the Mortgaged Property. The Servicer shall make all
required Servicing Advances and shall service and administer the Mortgage Loans
in accordance with Applicable Regulations, and shall provide to the Mortgagor
any reports required to be provided to them thereby. The Trustee shall execute
and deliver to the Servicer within at least fifteen (15) Business Day of
receipt, upon request, any powers of attorney furnished to it by the Servicer
empowering the Servicer to execute and deliver instruments of satisfaction or
cancellation, or of partial or full release or discharge, and to foreclose upon
or otherwise liquidate any Mortgaged Property, and to appeal, prosecute or
defend in any court action relating to the Mortgage Loans or the Mortgaged
Properties, in accordance with this Agreement, and the Trustee shall execute and
deliver such other documents as the Servicer may request, necessary or
appropriate to enable the Servicer to service and administer the Mortgage Loans
and carry out its duties hereunder, in each case in accordance with Servicing
Standard (and the Trustee shall have no liability for misuse of any such powers
of attorney by the Servicer). Notwithstanding anything contained herein to the
contrary, the Servicer shall not without the Trustee's written consent: (i)
initiate any action, suit or proceeding solely under the Trustee's name without
indicating the Servicer's representative capacity or (ii) take any action with
the intent to cause, and which results in, the Trustee being registered to do
business in any state.

            In servicing and administering the Mortgage Loans, the Servicer
shall employ procedures including collection procedures and exercise the same
care that it customarily employs and exercises in servicing and administering
mortgage loans for its own account giving due consideration to accepted mortgage
servicing practices of prudent lending institutions and the Certificateholders'
reliance on the Servicer.

            The Servicer shall give prompt notice to the Trustee of any action,
of which the Servicer has actual knowledge, to (i) assert a claim against the
Trust Fund or (ii) assert jurisdiction over the Trust Fund.

            Notwithstanding anything in this Agreement to the contrary, in the
event of a voluntary Principal Prepayment in full of a Mortgage Loan, the
Servicer may not waive any Prepayment Charge or portion thereof required by the
terms of the related Mortgage Note unless (i)(a) the Servicer determines that
such waiver is standard and customary in servicing similar mortgage loans, (b)
such waiver relates to a default or a reasonably foreseeable default and (c)
would, in the reasonable judgment of the Servicer, maximize recovery of
Liquidation Proceeds for such Mortgage Loan, taking into account the value of
such Prepayment Charge, or (ii) the enforceability thereof is limited (1) by
bankruptcy, insolvency, moratorium, receivership, or other similar law relating
to creditors' rights generally or (2) due to acceleration in connection with a
foreclosure or other involuntary payment. If the Servicer has waived or does not
collect all or a portion of a Prepayment Charge relating to a voluntary
Principal Prepayment in full due to any action or omission of the Servicer,
other than as provided above, the Servicer shall, on the date on which the
Principal Prepayment in full is remitted to the Trustee, deliver to the Trustee
the Servicer Prepayment Charge Amount with respect to such Mortgage Loan for
distribution in accordance with the terms of this Agreement.

            In the event that a Prepayment Charge due with respect to any
Mortgage Loan is not timely received by the Servicer, the Servicer shall use
commercially reasonable efforts to determine whether the Originator is obligated
to pay a related Originator Prepayment Charge Payment Amount, and if the
Servicer determines that a Originator Prepayment Charge Payment Amount is due,
the Servicer shall promptly notify the Originator, and the Servicer shall
enforce the Originator's obligations to pay in a timely manner any such
Originator Prepayment Charge Payment Amounts and, to the extent that such
amounts are received by the Servicer, shall cause such amounts to be deposited
into the Collection Account within one Business Day of receipt.

            Section 3.02 Collection of Mortgage Loan Payments.

            Continuously from the date hereof until the principal and interest
on all Mortgage Loans are paid in full or as long as the Mortgage Loan remains
subject to this Agreement, the Servicer will diligently collect all payments due
under each Mortgage Loan when the same shall become due and payable and shall,
to the extent such procedures shall be consistent with this Agreement and
Applicable Regulations, follow such collection procedures as it follows with
respect to mortgage loans comparable to the Mortgage Loans and held for its own
account. Further, the Servicer will take special care in ascertaining and
estimating on escrowed Mortgage Loans annual ground rents, taxes, assessments,
water rates, fire and hazard insurance premiums, mortgage insurance premiums,
and all other charges that, as provided in the Mortgage, will become due and
payable to that end that the installments payable by the Mortgagors will be
sufficient to pay such charges as and when they become due and payable.

            Section 3.03 Realization Upon Defaulted Mortgage Loans.

            In the event that any payment due under any Mortgage Loan is not
paid when the same becomes due and payable, or in the event the Mortgagor fails
to perform any other covenant or obligation under the Mortgage Loan and such
failure continues beyond any applicable grace period, the Servicer shall take
such action as it shall deem to be in the best interest of the
Certificateholders. With respect to any defaulted Mortgage Loan, the Servicer
shall have the right to review the status of the related forbearance plan and,
subject to the second paragraph of Section 3.01, may modify such forbearance
plan; including extending the Mortgage Loan repayment date for a period of one
year or reducing the Mortgage Interest Rate up to 50 basis points.

            In connection with a foreclosure or other conversion, the Servicer
shall exercise such rights and powers vested in it hereunder and use the same
degree of care and skill in its exercise as prudent mortgage servicers would
exercise or use under the circumstances in the conduct of their own affairs and
consistent with Applicable Regulations and the Servicing Standards, including,
without limitation, advancing funds for the payment of taxes and insurance
premiums.

            Notwithstanding the foregoing provisions of this Section 3.03, 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 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
Trust 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 received the prior written consent of the NIMS Insurer and has received a
prudent report prepared by a Person who regularly conducts environmental audits
using customary industry standards, that:

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

            B. 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 Certificateholders to take such
actions with respect to the affected Mortgaged Property.

            The cost of the environmental audit report contemplated by this
Section 3.03 shall be advanced by the Servicer, subject to the Servicer's right
to be reimbursed therefor from the Collection Account as provided in Section
3.05(iv).

            If the Servicer determines, as described above, that it is in the
best economic interest of the Certificateholders 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 Certificateholders. The cost of any such compliance,
containment, clean-up 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 3.05.

            Section 3.04 Collection Account, Distribution Account and Reserve
Accounts.

            (a) The Servicer shall segregate and hold all funds collected and
received pursuant to each Mortgage Loan separate and apart from any of its own
funds and general assets and shall establish and maintain one or more Collection
Accounts. Each Collection Account shall be an Eligible Account.

            The Servicer shall deposit or cause to be deposited on a daily basis
and in no event more than one Business Day after receipt thereof in the clearing
account (which must be an Eligible Account) in which it customarily deposits
payments and collections on mortgage loans in connection with its mortgage loan
servicing activities, and shall thereafter deposit in the Collection Account, in
no event more than one Business Day after deposit of such funds in the clearing
account, and retain therein, the following payments and collections received or
made by it after the Cut-off Date with respect to the Mortgage Loans (other than
in respect of principal and interest due on or before the Cut-off Date):

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

            (ii) all payments on account of interest on the Mortgage Loans
      adjusted to the Mortgage Interest Rate less the Servicing Fee Rate;

            (iii) all Liquidation Proceeds and any Subsequent Recoveries;

            (iv) all Insurance Proceeds including amounts required to be
      deposited pursuant to Section 3.10, other than proceeds to be held in the
      Escrow Account and applied to the restoration or repair of the Mortgaged
      Property or released to the Mortgagor in accordance with the Servicer's
      normal servicing procedures, the loan documents or applicable law;

            (v) all Condemnation Proceeds affecting any Mortgaged Property which
      are not released to the Mortgagor in accordance with the Servicer's normal
      servicing procedures, the loan documents or applicable law;

            (vi) any amounts required to be deposited by the Servicer in
      connection with any REO Property pursuant to Section 3.13;

            (vii) all Prepayment Charges collected by the Servicer in connection
      with the voluntary Principal Prepayment in full of any Mortgage Loan, all
      Originator Prepayment Charge Payment Amounts paid by the Originator and
      all Servicer Prepayment Charge Payment Amounts required to be paid by the
      Servicer pursuant to Section 3.01 in connection with any such Principal
      Prepayment; and

            (viii) all amounts required to be deposited by the Servicer pursuant
      to Section 2.03.

            Any interest paid on funds deposited in the Collection Account,
subject to Section 3.25, shall accrue to the benefit of the Servicer and the
Servicer shall be entitled to retain and withdraw such interest from the
Collection Account pursuant to Section 3.05(v). The foregoing requirements for
deposit from the Collection Account shall be exclusive, it being understood and
agreed that, without limiting the generality of the foregoing, payments in the
nature of late payment charges, bad check fees, prepayment charges that are not
Prepayment Charges, Originator Prepayment Charge Payment Amounts or Servicer
Prepayment Charge Payment Amounts, assumption fees and other similar fees need
not be deposited by the Servicer in the Collection Account. Amounts deposited in
the Collection Account in error may be withdrawn by the Servicer at any time.

            (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 Trustee in immediately
available funds for deposit in the Distribution Account by 1:00 p.m. New York
time on the Servicer Remittance Date, (i) that portion of the Available Funds
(calculated without regard to the references in the definition thereof to
amounts that may be deposited to the Distribution Account from a different
source as provided herein) then on deposit in the Collection Account, (ii) the
amount of all Prepayment Charges collected by the Servicer in connection with
the voluntary Principal Prepayment in full of any of the Mortgage Loans then on
deposit in the Collection Account (other than any such Prepayment Charges
received after the related Prepayment Period) and (iii) any Originator
Prepayment Charge Payment Amount or any Servicer Prepayment Charge Payment
Amount. Amounts in the Distribution Account shall be deemed to be held on behalf
of the related REMICs and the Grantor Trust in accordance with the REMIC
distributions set forth in Section 4.08. The Trustee shall be entitled to
withdraw from the Distribution Account any amounts owing to it pursuant to
Section 8.05 and Section 9.01(c) prior to the distribution of any amounts on
deposit to the Certificateholders; provided, however, in the case of amounts
owing to it other than the Trustee Fee, the Trustee shall provide the Depositor,
the NIMS Insurer and the Servicer with a written account of such amounts five
Business Days prior to withdrawing such funds. In connection with any failure by
the Servicer to make any remittance required to be made by the Servicer to the
Trustee for deposit in the Distribution Account on the day and by the time such
remittance is required to be made under the terms of this Section 3.04(b)
(without giving effect to any grace or cure period), the Servicer shall pay to
the Trustee for the account of the Trustee interest at the prime rate of United
States money center commercial banks as published in The Wall Street Journal on
any amount not timely remitted from and including the day such remittance was
required to be made to, but not including, the day on which such remittance was
actually made.

            (c) Funds in the Collection Account and the Distribution Account may
be invested in Eligible Investments in accordance with the provisions set forth
in Section 3.25. The Servicer shall give 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) 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 the Servicer 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 in respect of REMIC 1:

            (i) any Advances, as required pursuant to Section 4.07;

            (ii) any Stayed Funds, as soon as permitted by the federal
      bankruptcy court having jurisdiction in such matters;

            (iii) any amounts required to be delivered by the Servicer to the
      Trustee for deposit in the Distribution Account pursuant to Sections 2.03,
      3.04, 3.13, 3.15, 3.16, 3.23, 3.24, 4.07 or 10.01; and

            (iv) any amounts required to be deposited by the Servicer pursuant
      to Section 3.11 in connection with the deductible clause in any blanket
      hazard insurance policy, such deposit being made from the Servicer's own
      funds, without reimbursement therefor.

            (e) Promptly upon receipt of any Stayed Funds, whether from the
Servicer, a trustee in bankruptcy, or federal bankruptcy court or other source,
the Trustee shall notify the Servicer of such receipt and deposit such funds in
the Distribution Account, subject to withdrawal thereof as permitted hereunder.
In addition, the Trustee shall deposit in the Distribution Account any amounts
required to be deposited pursuant to Section 3.25(b) in connection with losses
realized on Eligible Investments with respect to funds held in the Distribution
Account.

            (f) Any Prepayment Charges, Originator Prepayment Charge Payment
Amounts and Servicer Prepayment Charge Payment Amounts deposited pursuant to
Section 3.04(a)(vii) shall not be assets of any REMIC created hereunder, but
shall be considered assets of the Grantor Trust held by the Trustee for the
benefit of the Class P Certificateholders.

            (g) (i) The Trustee shall establish and maintain the Class A-1
Reserve Account, held in trust for the benefit of the Holders of the Class A-1
Certificates. The Trustee shall deposit in the Class A-1 Reserve Account on the
date received by it, any Class A-1 Yield Maintenance Agreement Payment received
from the Class A-1 Yield Maintenance Agreement Provider for the related
Distribution Date. The Trustee shall establish and maintain the Group 2-A
Reserve Account, held in trust for the benefit of the Holders of the Class A-2,
Class A-3 and Class A-4 Certificates. The Trustee shall deposit in the Group 2-A
Reserve Account on the date received by it, any Group 2-A Yield Maintenance
Agreement Payment received from the Group 2-A Yield Maintenance Agreement
Provider for the related Distribution Date. The Trustee shall establish and
maintain the Class M Reserve Account, held in trust for the benefit of the
Holders of the Class M Certificates. The Trustee shall deposit in the Class M
Reserve Account on the date received by it, any Class M Yield Maintenance
Agreement Payment received from the Class M Yield Maintenance Agreement Provider
for the related Distribution Date. On each Distribution Date, the Trustee shall
withdraw from the Class A-1 Reserve Account any Class A-1 Yield Maintenance
Agreement Payment, shall withdraw from the Group 2-A Reserve Account any Group
2-A Yield Maintenance Agreement Payment and shall withdraw from the Class M
Reserve Account any Class M Yield Maintenance Agreement Payment and apply them
in the following order of priority:

                  (A) to the Class A-1 Certificates from the Class A-1 Reserve
            Account, any remaining unpaid Cap Carryover Amount for such Class
            for such Distribution Date (after distributions to the Class A-1
            Certificates pursuant to Section 4.02(b) hereof);

                  (B) concurrently, to the Class A-2, Class A-3 and Class A-4
            Certificates from the Group 2-A Reserve Account, pro rata in
            accordance with their Certificate Principal Balances immediately
            prior to the Distribution Date, any remaining unpaid Cap Carryover
            Amounts for such Classes for such Distribution Date (after
            distributions to the Class A-2, Class A-3 and Class A-4 Certificates
            pursuant to Section 4.02(b) hereof);

                  (C) to the Class M Certificates from the Class M Reserve
            Account, in each case only up to the Class M Cap Amount for the
            related Class, any remaining unpaid Cap Carryover Amounts for such
            Classes for such Distribution Date (after distributions to the Class
            M Certificates pursuant to Section 4.02(b) hereof), distributed
            sequentially, to the Class M-1, Class M-2, Class M-3, Class M-4,
            Class M-5, Class M-6 and Class M-7 Certificates;

                  (D) concurrently, to the Class A-2, Class A-3 and Class A-4
            Certificates, from the Group 2-A Reserve Account, pro rata in
            accordance with the remaining unpaid Cap Carryover Amounts for such
            Classes for such Distribution Date, any remaining unpaid Cap
            Carryover Amounts for such Classes for such Distribution Date (after
            distributions to the Class A-2, Class A-3 and Class A-4 Certificates
            pursuant to Section 4.02(b) hereof and clause (B) above);

                  (E) to the Class M Certificates from the Class M Reserve
            Account, any remaining unpaid Cap Carryover Amounts without regard
            to the Class M Cap Amount for such Classes for such Distribution
            Date (after distributions pursuant to Section 4.02(b) hereof and
            clause (C) above) distributed sequentially, to the Class M-1, Class
            M-2, Class M-3, Class M-4, Class M-5, Class M-6 and Class M-7
            Certificates; and

                  (F) to the Class CE Certificates, any remaining amounts on
            deposit in the Reserve Accounts.

            (ii) The Trustee shall account for each Reserve Account as an asset
      of a grantor trust under subpart E, part I of subchapter J of the Code and
      not an asset of any REMIC created pursuant to this Agreement. The
      beneficial owner of each Reserve Account is the Class CE
      Certificateholder. For all federal tax purposes, amounts transferred or
      reimbursed by REMIC 2 to any Reserve Account shall be treated as
      distributions by the Trustee to the Class CE Certificateholder.

            (iii) Any Cap Carryover Amounts paid by the Trustee pursuant to this
      Section 3.04(g) to the Offered Certificates and the Class M-7 Certificates
      shall be accounted for by the Trustee as amounts paid first to the Class
      CE Certificates and then to the respective Class or Classes of Offered
      Certificates and the Class M-7 Certificates from the Grantor Trust. In
      addition, the Trustee shall account for the Offered Certificates' and the
      Class M-7 Certificates' rights to receive payments of Cap Carryover
      Amounts as rights in limited recourse interest rate cap contracts written
      by the Class CE Certificates in favor of each Class of Offered
      Certificates and the Class M-7 Certificates.

            (iv) For federal tax return and information reporting, the right of
      the Holders of the Offered Certificates and the Class M-7 Certificates to
      receive payments under the Class A-1 Yield Maintenance Agreement, Group
      2-A Yield Maintenance Agreement and Class M Yield Maintenance Agreement in
      respect of any related Yield Maintenance Agreement Payments shall be
      assigned a value of zero.

            Section 3.05 Permitted Withdrawals From the Collection Account.

            The Servicer may, from time to time, withdraw from the Collection
Account for the following purposes:

            (i) to remit to the Trustee for deposit in the Distribution Account
      the amounts required to be so remitted pursuant to Section 3.04(b) or
      permitted to be so remitted pursuant to the first sentence of Section
      3.04(d);

            (ii) to reimburse itself for (a) any unreimbursed Advances to the
      extent of amounts received which represent Late Collections (net of the
      related Servicing Fees) of Monthly Payments, Liquidation Proceeds and
      Insurance Proceeds on Mortgage Loans with respect to which such Advances
      were made in accordance with the provisions of Section 4.07; (b) any
      unreimbursed Advances with respect to the final liquidation of a Mortgage
      Loan that are Nonrecoverable Advances, but only to the extent that Late
      Collections, Liquidation Proceeds and Insurance Proceeds received with
      respect to such Mortgage Loan are insufficient to reimburse the Servicer
      for such unreimbursed Advances; or (c) subject to Section 4.07(b), any
      unreimbursed Advances to the extent of funds held in the Collection
      Account for future distribution that were not included in Available Funds
      for the preceding Distribution Date;

            (iii) to reimburse itself for (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, Liquidation Proceeds,
      Insurance Proceeds and condemnation proceeds received with respect to such
      Mortgage Loan, and (c) any Servicing Advances with respect to the final
      liquidation of a Mortgage Loan that are Nonrecoverable Advances, but only
      to the extent that Late Collections, Liquidation Proceeds and Insurance
      Proceeds received with respect to such Mortgage Loan are insufficient to
      reimburse the Servicer for Servicing Advances;

            (iv) to reimburse itself for any amounts paid or expenses incurred
      pursuant to Section 3.03 (and not otherwise previously reimbursed);

            (v) to pay to itself as servicing compensation (a) any interest
      earned on funds in the Collection Account (all such interest to be
      withdrawn monthly not later than each Servicer Remittance Date), (b) the
      Servicing Fee from that portion of any payment or recovery as to interest
      to a particular Mortgage Loan to the extent not retained pursuant to
      Section 3.04(a)(ii) and (c) any Prepayment Interest Excess;

            (vi) to pay or reimburse itself for any amounts payable or paid
      pursuant to Section 6.03 (and not otherwise previously reimbursed); and

            (vii) to clear and terminate the Collection Account upon the
      termination of this Agreement.

            The foregoing requirements for withdrawal from the Collection
Account shall be exclusive. 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.

            Section 3.06 Establishment of Escrow Accounts; Deposits in Escrow
Accounts.

            The Servicer shall segregate and hold all funds collected and
received pursuant to each Mortgage Loan which constitute Escrow Payments
separate and apart from any of its own funds and general assets and shall
establish and maintain one or more Escrow Accounts, in the form of time deposit
or demand accounts. A copy of such letter agreement shall be furnished to the
Trustee upon request. The Escrow Account shall be an Eligible Account.

            The Servicer shall deposit or cause to be deposited on a daily basis
and in no event more than one Business Day after receipt thereof in the clearing
account (which must be an Eligible Account) in which it customarily deposits
payments and collections on mortgage loans in connection with its mortgage loan
servicing activities, and shall thereafter deposit in the Escrow Account or
Accounts, in no event more than one Business Day after deposit of such funds in
the clearing account, and retain therein, (i) all Escrow Payments collected on
account of the Mortgage Loans, for the purpose of effecting timely payment of
any such items as required under the terms of this Agreement, and (ii) all
Insurance Proceeds which are to be applied to the restoration or repair of any
Mortgaged Property. The Servicer shall make withdrawals therefrom only to effect
such payments as are required under this Agreement, and for such other purposes
as shall be set forth in, or in accordance with, Section 3.07. The Servicer
shall be entitled to retain any interest paid on funds deposited in the Escrow
Account by the depository institution other than interest on escrowed funds
required by law to be paid to the Mortgagor and, to the extent required by the
related Mortgage Loan or Applicable Regulations, the Servicer shall pay interest
on escrowed funds to the Mortgagor notwithstanding that the Escrow Account is
non-interest bearing or that interest paid thereon is insufficient for such
purposes.

            Section 3.07 Permitted Withdrawals From Escrow Account.

            Withdrawals from the Escrow Account may be made by the Servicer (i)
to effect timely payments of ground rents, taxes, assessments, water rates,
fire, flood and 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) to reimburse the Servicer for any Servicing Advance
made by the Servicer with respect to a related Mortgage Loan but only from
amounts received on the related Mortgage Loan which represent late payments or
Late Collections of Escrow Payments thereunder with respect to taxes and
assessments and with respect to hazard insurance, (iii) to refund to the
Mortgagor any funds as may be determined to be overages, (iv) for transfer to
the Collection Account in accordance with the terms of this Agreement, (v) for
application to restoration or repair of the Mortgaged Property, (vi) to pay to
the Servicer, or to the Mortgagor to the extent required by the related Mortgage
Loan or Applicable Regulations, any interest paid on the funds deposited in the
Escrow Account, (vii) to clear and terminate the Escrow Account on the
termination of this Agreement, or (viii) to transfer to the Collection Account
any insurance proceeds. As part of its servicing duties, the Servicer shall pay
to the Mortgagor interest on funds in the Escrow Account, to the extent required
by the related Mortgage Loan or Applicable Regulations, and to the extent that
interest earned on funds in the Escrow Account is insufficient, shall pay such
interest from its own funds, without any reimbursement therefor.

            In the event the Servicer shall deposit in the Escrow Account any
amount not required to be deposited therein, it may at any time withdraw such
amount from the Escrow Account, any provision herein to the contrary
notwithstanding.

            Section 3.08 Payment of Taxes, Insurance and Other Charges;
Collections Thereunder.

            With respect to each Mortgage Loan that provides for Escrow
Payments, the Servicer shall maintain accurate records reflecting the status of
ground rents, taxes, assessments, water rates and other charges which are or may
become a lien upon the Mortgaged Property and the status of fire, flood and
hazard insurance coverage and shall obtain, from time to time, all bills for the
payment of such charges (including renewal premiums) and shall 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). To the extent that the Mortgage does not
provide for Escrow Payments, the Servicer shall use its best efforts to
determine that any such payments are made by the Mortgagor at the time they
first become due. If any such payment has not been made, the Servicer will
advance or cause to be advanced funds necessary to avoid the lapse of insurance
coverage on the Mortgaged Property and to assure that no Mortgaged Property is
lost to a tax sale or foreclosure as a result of a tax lien.

            Section 3.09 Transfer of Accounts.

            The Servicer may transfer the Collection Account and the Escrow
Account to a different depository institution from time to time. Upon such
transfer, the Servicer shall deliver to the Trustee, the NIMS Insurer and the
Depositor, a certification or letter agreement, as the case may be, as required
pursuant to Sections 3.04 and 3.06.

            Section 3.10 Maintenance of Hazard Insurance.

            The Servicer shall cause to be maintained for each Mortgage Loan
fire and hazard insurance with extended coverage as is customary in the area
where the Mortgaged Property is located in an amount which is at least equal to
the lesser of (i) the amount necessary to fully compensate for any damage or
loss to the improvements which are a part of such property on a replacement cost
basis or (ii) the Principal Balance of the Mortgage Loan, in each case in an
amount not less than such amount as is necessary to prevent the Mortgagor and/or
the Mortgagee from becoming a co-insurer. If the Mortgaged Property is in an
area identified in the Federal Register by the Flood 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 meeting the
requirements of the current guidelines of the Federal Insurance Administration
with a generally acceptable insurance carrier, in an amount representing
coverage not less than the least of (i) the Principal Balance of the Mortgage
Loan, (ii) the maximum insurable value of the improvements securing such
Mortgage Loan or (iii) the maximum amount of insurance which is available under
the National Flood Insurance Act of 1968, as amended. The Servicer shall also
maintain on the REO Property for the benefit of the Certificateholders, (x) fire
and hazard insurance with extended coverage in an amount which is at least equal
to the lesser of (i) 100% of the maximum insurable value of the improvements
securing the Mortgage Loan and (ii) the outstanding Principal Balance of the
Mortgage Loan at the time it became an REO Property, (y) public liability
insurance and, (z) to the extent required and available under the National Flood
Insurance Act of 1968, as amended, flood insurance in an amount as provided
above. Any amounts collected by the Servicer under any such policies other than
amounts to be deposited in the Escrow Account and applied to the restoration or
repair of the Mortgaged Property or REO Property, or released to the Mortgagor
in accordance with the Servicer's normal servicing procedures, shall be
deposited in the Collection Account, subject to withdrawal pursuant to Section
3.05. It is understood and agreed that no earthquake or other additional
insurance is required to be maintained by the Servicer or the Mortgagor or
maintained on property acquired in respect of the Mortgage Loan, other than
pursuant to such Applicable Regulations as shall at any time be in force and as
shall require such additional insurance. All such policies shall be endorsed
with standard mortgagee clauses with loss payable to the Servicer and shall
provide for at least thirty days prior written notice of any cancellation,
reduction in the amount of or material change in coverage to the Servicer. The
Servicer shall not interfere with the Mortgagor's freedom of choice in selecting
either his insurance carrier or agent, provided, however, that the Servicer
shall not accept any such insurance policies from insurance companies unless
such companies currently reflect a general policy rating of B:III or better in
Best's Key Rating Guide and are licensed to do business in the state wherein the
property subject to the policy is located.

            Section 3.11 Maintenance of Mortgage Impairment Insurance Policy.

            In the event that the Servicer shall obtain and maintain a blanket
policy issued by an insurer that has a general policy rating of B:III or better
in Best's Key Rating Guide insuring against hazard losses on all of the Mortgage
Loans, then, to the extent such policy provides coverage in an amount equal to
the amount required pursuant to Section 3.10 and otherwise complies with all
other requirements of Section 3.10, it shall conclusively be deemed to have
satisfied its obligations as set forth in Section 3.10, 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 Section 3.10,
and there shall have been a loss which would have been covered by such policy,
deliver to the Trustee for deposit in the Distribution Account the amount not
otherwise payable under the blanket policy because of such deductible clause,
which amount shall not be reimbursable to the Servicer from the Trust Fund. In
connection with its activities as servicer of the Mortgage Loans, the Servicer
agrees to prepare and present, on behalf of the Trustee, claims under any such
blanket policy in a timely fashion in accordance with the terms of such policy.
Upon request of the Trustee, the Servicer shall cause to be delivered to the
Trustee a certified true copy of such policy and a statement from the insurer
thereunder that such policy shall in no event be terminated or materially
modified without thirty days prior written notice to the Trustee.

            Section 3.12 Fidelity Bond, Errors and Omissions Insurance.

            The Servicer shall maintain, at its own expense, a blanket fidelity
bond (the "Fidelity Bond") and an errors and omissions insurance policy, with
broad coverage with financially responsible companies on all officers, employees
or other persons acting in any capacity with regard to the Mortgage Loans to
handle funds, money, documents and papers relating to the Mortgage Loans. The
Fidelity Bond and errors and omissions insurance shall be in the form of the
Mortgage Banker's Blanket Bond and shall protect and insure the Servicer against
losses, including forgery, theft, embezzlement, fraud, errors and omissions and
negligent acts of such persons. Such Fidelity Bond shall also protect and insure
the Servicer against losses in connection with the failure to maintain any
insurance policies required pursuant to this Agreement and the release or
satisfaction of a Mortgage Loan without having obtained payment in full of the
indebtedness secured thereby. No provision of this Section 3.12 requiring the
Fidelity Bond and errors and omissions insurance shall diminish or relieve the
Servicer from its duties and obligations as set forth in this Agreement. The
minimum coverage under any such bond and insurance policy shall be at least
equal to the corresponding amounts required by Fannie Mae in the Fannie Mae MBS
Selling and Servicing Guide or by Freddie Mac in the Freddie Mac Servicer's
Guide. Upon request of the Trustee or the NIMS Insurer, the Servicer shall cause
to be delivered to the requesting party a certified true copy of the Fidelity
Bond and errors and omissions insurance policy and a statement from the surety
and the insurer that such Fidelity Bond and errors and omissions insurance
policy shall in no event be terminated or materially modified without thirty
days' prior written notice to the Trustee.

            Section 3.13 Title, Management and Disposition of REO Property.

            (a) In the event that title to a Mortgaged Property is acquired in
foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale
shall be taken (pursuant to a limited power of attorney to be provided by the
Trustee to the Servicer) in the name of the Trustee or its nominee, on behalf of
the Certificateholders, or in the event the Trustee is not authorized or
permitted to hold title to real property in the state where the REO Property is
located, or would be adversely affected under the "doing business" or tax laws
of such state by so holding title, the deed or certificate of sale shall be
taken in the name of such Person or Persons as shall be consistent with an
Opinion of Counsel obtained by the Servicer from an attorney duly licensed to
practice law in the state where the REO Property is located. Any Person or
Persons holding such title other than the Trustee shall acknowledge in writing
that such title is being held as nominee for the benefit of the Trustee.

            (b) In the event that the Trust Fund acquires any REO Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Servicer shall dispose of such REO Property before the end of
the third taxable year beginning after the year of its acquisition by the Trust
Fund for purposes of Section 860G(a)(8) of the Code unless the Servicer has
received a grant of extension from the Internal Revenue Service of the
above-mentioned grace period such that the holding by the Trust Fund of such REO
Property subsequent to such period will not: (i) result in the imposition of any
tax on "prohibited transactions" as defined in Section 860F of the Code; or (ii)
cause any REMIC constituting any part of the Trust Fund to fail to qualify as a
REMIC at any time that any Certificates (other than the Class P Certificates)
are outstanding, in which case the Trust Fund may continue to hold such REO
Property.

            Subject to compliance with applicable laws and regulations as shall
at any time be in force, and notwithstanding any other provisions of this
Agreement, no REO Property acquired by the Trust Fund shall be rented (or
allowed to continue to be rented) or otherwise used by or on behalf of the Trust
Fund in such a manner or pursuant to any terms that would: (i) cause such REO
Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code; or (ii) subject any REMIC constituting part of
the Trust Fund to the imposition of any federal income taxes on the income
earned from such REO Property, including any taxes imposed by reason of Sections
860F or 860G(c) of the Code, unless the Servicer has agreed to indemnify and
hold harmless the Trust Fund with respect to the imposition of any such taxes.

            The Servicer shall manage, conserve, protect and operate each REO
Property for the Certificateholders and the Trust Fund 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 the related REMIC 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. The Servicer shall cause each
REO Property to be inspected promptly upon the acquisition of title thereto and
shall cause each REO Property to be inspected at least annually thereafter. The
Servicer shall make or cause to be made a written or electronic report of each
such inspection. Such reports shall be retained in the Mortgage File and copies
thereof shall be forwarded by the Servicer to the Trustee upon request. The
Servicer shall attempt to sell the same (and may temporarily rent the same) on
such terms and conditions as the Servicer deems to be in the best interest of
the Certificateholders and the Trust Fund.

            With respect to each REO Property, the Servicer shall account
separately for each REO Property with respect to all funds collected and
received in connection with the operation of such REO Property.

            The Servicer shall deposit or cause to be deposited, on a daily
basis, within one Business Day of receipt, in the Collection Account, all
revenues received with respect to each REO Property and shall withdraw therefrom
funds necessary for the proper operation, management and maintenance of the
related REO Property, including the cost of maintaining any hazard insurance
pursuant to Section 3.10 hereof and the fees of any managing agent acting on
behalf of the Servicer.

            The Servicer shall furnish to the Trustee, on each Servicer
Remittance Date, an operating statement for each REO Property covering the
operation of each REO Property for the previous month. Such operating statement
shall be accompanied by such other information as the Trustee shall reasonably
request.

            The Servicer shall use its best efforts to dispose of the REO
Property as promptly as is practically consistent with protecting the
Certificateholders' interests.

            Each REO Disposition shall be carried out by the Servicer at such
price and upon such terms and conditions as the Servicer deems to be in the best
interest of the Certificateholders. If as of the date title to any REO Property
was acquired by the Servicer there were outstanding unreimbursed Servicing
Advances, Servicing Fees and Advances with respect to the REO Property, the
Servicer, upon an REO Disposition of such REO Property, shall be entitled to
reimbursement for any related unreimbursed Servicing Advances, Servicing Fees
and Advances from proceeds received in connection with such REO Disposition. The
proceeds from the REO Disposition, net of any payment to the Servicer as
provided above, shall be deposited in the Collection Account for transfer to the
Distribution Account on the succeeding Servicer Remittance Date in accordance
with Section 3.04(a)(vi).

            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 and an Opinion of Counsel is obtained by the Servicer to the
effect that such sale shall not cause any REMIC constituting part of the Trust
Fund to fail to qualify as a REMIC).

            Section 3.14 Due-on-Sale Clauses; Assumption and Substitution
Agreements.

            When a Mortgaged Property has been or is about to be conveyed by the
Mortgagor, the Servicer shall, to the extent it has knowledge of such conveyance
or prospective conveyance, exercise its rights to accelerate the maturity of the
related Mortgage Loan under any "due-on-sale" clause contained in the related
Mortgage or Mortgage Note; provided, however, that the Servicer shall not
exercise any such right if the "due-on-sale" clause, in the reasonable belief of
the Servicer, is not enforceable under applicable law. In such event, the
Servicer shall make reasonable efforts to enter into an assumption and
modification agreement with the Person to whom such property has been or is
about to be conveyed, pursuant to which such Person becomes liable under the
Mortgage Note and, unless prohibited by applicable law or the Mortgage, the
Mortgagor remains liable thereon. If the foregoing is not permitted under
applicable law, the Servicer is 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 Mortgagor and
becomes liable under the Note; provided that no such substitution will be
permitted unless such person satisfies the underwriting criteria of the Servicer
and has a credit score at least equal to that of the original Mortgagor. The
Mortgage Loan, as assumed, shall conform in all respects to the requirements,
representations and warranties of this Agreement. The Servicer shall not take or
enter into any assumption and modification agreement, however, unless (to the
extent practicable under the circumstances) it shall have received confirmation,
in writing, of the continued effectiveness of any applicable hazard insurance
policy. The Servicer shall notify the Trustee that any such assumption or
substitution agreement has been completed by forwarding to the Trustee the
original copy of such assumption or substitution agreement (indicating the
Mortgage File to which it relates) which copy shall be added by the Trustee to
the related Mortgage File and which 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. The Servicer shall be responsible for
recording any such assumption or substitution agreements. In connection with any
such assumption or substitution agreement, the Monthly Payment on the related
Mortgage Loan shall not be changed but shall remain as in effect immediately
prior to the assumption or substitution, the stated maturity or outstanding
principal amount of such Mortgage Loan shall not be changed nor shall any
required monthly payments of principal or interest be deferred or forgiven. Any
fee collected by the Servicer for consenting to any such conveyance or entering
into an assumption or substitution agreement shall be retained by or paid to the
Servicer as additional servicing compensation.

            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 any assumption which the Servicer may be
restricted by law from preventing, for any reason whatsoever.

            Section 3.15 Notification of Adjustments.

            On each Adjustment Date, the Servicer shall make Mortgage Interest
Rate adjustments for each Adjustable-Rate Mortgage Loan in compliance with the
requirements of the related Mortgage and Mortgage Note and Applicable
Regulations. The Servicer shall execute and deliver the notices required by each
Mortgage and Mortgage Note and Applicable Regulations regarding Mortgage
Interest Rate adjustments. Upon the discovery by the Servicer or the Trustee
that the Servicer has failed to adjust or has incorrectly adjusted a Mortgage
Interest Rate or a Monthly Payment pursuant to the terms of the related Mortgage
Note and Mortgage, the Servicer shall deliver to the Trustee for deposit in the
Distribution Account from its own funds the amount of any interest loss caused
thereby without reimbursement therefor; provided, however, the Servicer shall be
held harmless with respect to any Mortgage Interest Rate adjustments made by any
servicer prior to the Servicer.

            Section 3.16 Use of Subcontractors and Subservicers.

            To the extent the Servicer engages any Subcontractor or Subservicer
in connection with the performance of any of its duties under this Agreement,
the Servicer shall immediately notify the Depositor and the Trustee in writing
of such engagement and shall provide a written description (in form and
substance satisfactory to the Depositor) of the role and function of such
Subcontractor or Subservicer. To the extent the Depositor notifies the Servicer
and the Trustee that it has determined that any such Subcontractor or
Subservicer is a Servicing Function Participant, the Servicer shall cause such
Servicing Function Participant to prepare a separate assessment and attestation
report, as contemplated by Section 3.20 of this Agreement and deliver such
report to the Trustee as set forth in Section 3.31 of this Agreement. In
addition, to the extent the Depositor notifies the Servicer and the Trustee that
it has determined that any such Servicing Function Participant would be a
"servicer" within the meaning of Item 1101 of Regulation AB and meets the
criteria in Item 1108(a)(2)(i), (ii) or (iii) of Regulation AB (an "Additional
Servicer"), the Servicer shall cause such Additional Servicer (i) to prepare a
separate compliance statement as contemplated by Section 3.19 of this Agreement
and deliver such statement to the Trustee as set forth in Section 3.31 of this
Agreement and (ii) to provide the Depositor and the Trustee the information
required by Item 1108(b) and 1108(c) of Regulation AB (including, without
limitation, a copy of any Subservicing Agreement) within two Business Days
following such engagement such that the Trustee, pursuant to Section 3.31(d),
may accurately and timely report such event under Item 6.02 of Form 8-K pursuant
to the Exchange Act (if the Trust's Exchange Act reporting requirements have not
been suspended pursuant to Section 15(d) of the Exchange Act as set forth in
3.31(g)). To the extent the Servicer terminates any such Additional Servicer,
the Servicer shall provide the Depositor and the Trustee the information
required to enable the Trustee to accurately and timely report such event under
Item 6.02 of Form 8-K (if the Trust's Exchange Act reporting requirements have
not been suspended pursuant to Section 15(d) of the Exchange Act as set forth in
3.31(g)).

            Section 3.17 Trustee to Cooperate; Release of Files.

            (a) Upon the payment in full of any Mortgage Loan (including any
liquidation of such Mortgage Loan through foreclosure or otherwise, or the
receipt by the Servicer of a notification that payment in full will be escrowed
in a manner customary for such purposes), the Servicer shall deliver to the
Trustee, in written form (with two executed copies) or electronic form, of a
completed "Request for Release" in the form of Exhibit E. Upon receipt of such
Request for Release of Documents, the Trustee shall promptly release the related
Mortgage File within three (3) Business Days via overnight mail delivery (at the
expense of the Servicer), in trust, to (i) the Servicer, or (ii) such other
party identified in the related Request for Release. 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 direct result of the
negligence or willful misconduct by the Trustee in releasing the Mortgage File
as provided above. Upon any such payment in full, or the receipt of such
notification that such funds have been placed in escrow, the Trustee hereby
authorizes and empowers the Servicer to execute an instrument of satisfaction
(or assignment of Mortgage without recourse) regarding the Mortgaged Property
relating to such Mortgage, which instrument of satisfaction or assignment shall
be delivered to the Person or Persons entitled thereto against receipt therefor
of payment in full, it being understood and agreed that no expense incurred in
connection with such instrument of satisfaction or assignment, as the case may
be, shall be chargeable to the Collection Account.

            (b) From time to time and as appropriate in the servicing of any
Mortgage Loan, including, without limitation, foreclosure or other comparable
conversion of a Mortgage Loan or collection under any insurance policy relating
to a Mortgage Loan, the Trustee shall (except in the case of the payment or
liquidation pursuant to which the related Mortgage File is released to an escrow
agent or an employee, agent or attorney of the Trustee), upon written request of
the Servicer and delivery to the Trustee, in written form (with two executed
copies) or electronic form, of a "Request for Release" in the form of Exhibit E
signed by a Servicing Officer, release the related Mortgage File to the Servicer
within three (3) Business Days and shall execute such documents as shall be
necessary to the prosecution of any such proceedings, including, without
limitation, an assignment without recourse of the related Mortgage to the
Servicer. Such receipt shall obligate the Servicer to return the Mortgage File
to the Trustee when the need therefor by the Servicer no longer exists unless
the Mortgage Loan shall be liquidated, in which case, upon receipt of a Request
for Release evidencing such liquidation, the receipt shall be released by the
Trustee to the Servicer.

            (c) Subject to Section 3.01, the Servicer shall have the right to
accept applications of Mortgagors for consent to (i) partial releases of
Mortgages, (ii) alterations, (iii) removal, demolition or division of properties
subject to Mortgages, (iv) modifications, and (v) second mortgage subordination
agreements. No application for approval shall be considered by the Servicer
unless: (w) it has received an Opinion of Counsel, addressed to the Trustee
(which opinion shall not be an expense of the Trustee or the Trust Fund) that
such sale, disposition, substitution, acquisition or contribution will not
affect adversely the status of any REMIC constituting part of the Trust Fund as
a REMIC or cause any REMIC constituting part of the Trust Fund to be subject to
a tax on "prohibited transactions" or "contributions" pursuant to the REMIC
Provisions; (x) the provisions of the related Note and Mortgage have been
complied with; (y) the Combined Loan-to-Value Ratio and debt-to-income ratio
after any release does not exceed the maximum Combined Loan-to-Value Ratio and
debt-to-income ratio established in accordance with the underwriting standards
of the Mortgage Loans; and (z) the lien priority of the related Mortgage is not
affected. Upon receipt by the Trustee of a Servicing Officer's certificate
setting forth the action proposed to be taken in respect of a particular
Mortgage Loan and certifying that the criteria set forth in the immediately
preceding sentence have been satisfied, the Trustee shall execute and deliver to
the Servicer the consent or partial release so requested by the Servicer. A
proposed form of consent or partial release, as the case may be, shall accompany
any Servicing Officer's certificate delivered by the Servicer pursuant to this
paragraph.

            Section 3.18 Servicing Compensation.

            As compensation for its activities hereunder, the Servicer shall be
entitled to retain the amount of the Servicing Fee with respect to each Mortgage
Loan (including REO Properties) and any Prepayment Interest Excess. The Servicer
shall be entitled to retain additional servicing compensation in the form of
release fees, bad check charges, assumption fees, modification or extension
fees, late payment charges, prepayment charges that are not Prepayment Charges,
Originator Prepayment Charge Payment Amounts or Servicer Prepayment Charge
Payment Amounts, or any other service-related fees and similar items, to the
extent collected from Mortgagors.

            Section 3.19 Annual Statement as to Compliance.

            The Trustee and the Servicer shall deliver, and the Servicer shall
cause each Additional Servicer engaged by it to deliver, to the Depositor, the
Trustee and each Rating Agency on or before March 5 of each year or if such day
is not a Business Day, the next Business Day (with a 10 calendar day cure
period, but in no event later than March 15), commencing in March 20 , a
certificate in the form required by Item 1123 of Regulation AB, to the effect
that (i) an authorized officer of the Trustee, the Servicer or the Additional
Servicer, as the case may be, has reviewed (or a review has been made under his
or her supervision of) such party's activities under this Agreement, or such
other applicable agreement in the case of an Additional Servicer, during the
prior calendar year or portion thereof and (ii) to the best of such officer's
knowledge, based on such review, such party has fulfilled all of its obligations
under this Agreement, or such other applicable agreement in the case of an
Additional Servicer, in all material respects throughout the prior calendar year
or portion thereof or, if there has been a failure to fulfill any such
obligation in any material respect, specifying each such failure known to such
officer and the nature and status thereof. Promptly after receipt of each such
certificate, the Depositor shall review such certificate and, if applicable,
consult with the Servicer and the Trustee as to the nature of any failure to
fulfill any obligation under the Agreement, or such other applicable agreement
in the case of an Additional Servicer, in any material respect.

            Section 3.20 Annual Independent Certified Public Accountants'
Reports.

            (a) Each of the Servicer and the Trustee, at its own expense, shall
furnish, and shall cause any Servicing Function Participant engaged by it to
furnish, at such party's expense, to the Trustee and the Depositor, not later
than March 5 of each year or if such day is not a Business Day, the next
Business Day (with a 10 calendar day cure period, but in no event later than
March 15), commencing in March 20 , a report on an assessment of compliance with
the Servicing Criteria applicable to it that contains (A) a statement by such
party of its responsibility for assessing compliance with the Servicing Criteria
applicable to it, (B) a statement that such party used the Servicing Criteria to
assess compliance with the Servicing Criteria applicable to it, (C) such party's
assessment of compliance with the Servicing Criteria applicable to it as of and
for the fiscal year covered by the Form 10-K required to be filed pursuant to
Section 3.31, including, if there has been any material instance of
noncompliance with the Servicing Criteria applicable to it, an identification of
each such failure and the nature and status thereof, and (D) a statement that a
registered public accounting firm has issued an attestation report on such
party's assessment of compliance with the Servicing Criteria applicable to such
party as of and for such period.

            Each such assessment of compliance report shall be addressed to the
Depositor and the Servicer and signed by an authorized officer of the applicable
party, and shall address each of the Relevant Servicing Criteria set forth on
Exhibit Q hereto, or as set forth in the notification furnished to the Depositor
and the Trustee pursuant to Section 3.20(c). The Servicer and the Trustee hereby
acknowledge and agree that their respective assessments of compliance will cover
the items identified on Exhibit Q hereto as being covered by such party. The
parties to this Agreement acknowledge that where a particular Servicing
Criterion has multiple components, each party's assessment of compliance (and
related attestation of compliance) will relate only to those components that are
applicable to such party. Promptly after receipt of each such report on
assessment of compliance, the Depositor shall review each such report and, if
applicable, consult with the Servicer or the Trustee as to the nature of any
material instance of noncompliance with the Servicing Criteria applicable to it
(or any Servicing Function Participant engaged or utilized by the Servicer or
the Trustee, as applicable).

            (b) Each of the Servicer and the Trustee, at its own expense, shall
cause, and shall cause any Servicing Function Participant engaged by it, at such
party's expense, to cause, not later than March 5 of each year or if such day is
not a Business Day, the next Business Day (with a 10 calendar day cure period),
commencing in March 20 , a registered public accounting firm (which may also
render other services to the Servicer, the Trustee, or such other Servicing
Function Participants, as the case may be) and that is a member of the American
Institute of Certified Public Accountants to furnish a report to the Trustee and
the Depositor, to the effect that (i) it has obtained a representation regarding
certain matters from the management of such party, which includes an assertion
that such party has complied with the Servicing Criteria applicable to it, and
(ii) on the basis of an examination conducted by such firm in accordance with
standards for attestation engagements issued or adopted by the Public Company
Accounting Oversight Board, it is expressing an opinion as to whether such
party's assessment of compliance with the Servicing Criteria was fairly stated
in all material respects, or it cannot express an overall opinion regarding such
party's assessment of compliance with the Servicing Criteria. In the event that
an overall opinion cannot be expressed, such registered public accounting firm
shall state in such report why it was unable to express such an opinion. Such
report must be available for general use and not contain restricted use
language. If requested by the Depositor, such report shall contain or be
accompanied by a consent of such accounting firm to inclusion or incorporation
of such report in the Depositor's registration statement on Form S-3 relating to
the Offered Certificates and the Form 10-K for the Trust.

            Promptly after receipt of each such accountants' attestation report,
the Depositor shall review the report and, if applicable, consult with the
Servicer or the Trustee if such report (i) states that a party's assessment of
compliance was not fairly stated in any material respect or (ii) is unable to
state an overall opinion.

            (c) No later than 30 days following the end of each fiscal year for
the Trust for which a Form 10-K is required to be filed, (i) the Servicer shall
forward to the Trustee the name of each Servicing Function Participant engaged
by it and what Servicing Criteria will be addressed in the report on assessment
of compliance prepared by such Servicing Function Participant and (ii) the
Trustee shall forward to the Depositor the name of each Servicing Function
Participant engaged by it and what Servicing Criteria will be addressed in the
report on assessment of compliance prepared by such Servicing Function
Participant, in each case to the extent of any change from the prior year's
notice, if any.

            (d) Beginning with fiscal year 20 and thereafter, none of the
Servicer, the Trustee or any Servicing Function Participant engaged by such
parties shall be required to deliver or cause the delivery of any such
assessments or attestation reports until April 15 unless such party has received
written notice from the Depositor that a Form 10-K is required to be filed in
respect of the Trust for the preceding fiscal year.

            Section 3.21 Access to Certain Documentation and Information
Regarding the Mortgage Loans.

            (a) The Servicer shall provide to the Trustee, Certificateholders
that are federally insured savings and loan associations, the Office of Thrift
Supervision, the FDIC and the supervisory agents and examiners of each of the
foregoing (which, in the case of supervisory agents and examiners, may be
required by applicable state and federal regulations) access to the available
documentation regarding the Mortgage Loans, such access being afforded without
charge but only upon reasonable advance request and during normal business hours
at the offices of the Servicer designated by it.

            (b) The Servicer, in its capacity as Originator and Servicer, shall
afford the NIMS Insurer, upon reasonable advance notice, during normal business
hours, access to all records maintained by the Servicer in respect of its rights
and obligations hereunder and access to officers of the Servicer responsible for
such obligations. Upon request, the Servicer shall furnish to the NIMS Insurer
its most recent publicly available financial statements and such other
information relating to its capacity to perform its obligations under this
Agreement.

            Section 3.22 Duties of Credit Risk Manager.

            For and on behalf of the Depositor, the Credit Risk Manager shall
provide reports and recommendations as to loss mitigation activities concerning
Mortgage Loans that are past due, are in default, as to which there has been
commencement of foreclosure, as to which there has been forbearance in exercise
of remedies, as to which any obligor is the subject of bankruptcy, receivership,
or an arrangement of creditors, or which have become REO Properties. Such
reports and recommendations will be based upon information provided pursuant to
the Credit Risk Management Agreement. The Credit Risk Manager shall look solely
to the Servicer for all information and data (including loss and delinquency
information and data) and loan-level information and data relating to the
servicing of the Mortgage Loans.

            The Credit Risk Manager may be removed at any time by a vote of
Certificateholders holding Certificates evidencing at least 66 2/3% of the
aggregate Voting Rights of the Certificates. After any such termination, the
Credit Risk Manager shall have no further obligations hereunder, and shall no
longer be entitled to the Credit Risk Manager Fee.

            Section 3.23 Obligations of the Servicer in Respect of Compensating
Interest.

            Not later than the close of business on each Servicer Remittance
Date, the Servicer shall deliver to the Trustee for deposit in the Distribution
Account an amount ("Compensating Interest") equal to the lesser of (A) the
aggregate of the Prepayment Interest Shortfalls on the Mortgage Loans for the
related Distribution Date resulting from Principal Prepayments in full on the
Mortgage Loans during the related Prepayment Period and (B) the sum of (i) its
aggregate Servicing Fee received in the related Collection Period and (ii) any
Prepayment Interest Excess for the related Distribution Date. The Servicer shall
apply Compensating Interest to offset any Prepayment Interest Shortfalls
resulting from Principal Prepayments in full on the Mortgage Loans. The Servicer
shall not have the right to reimbursement for any amounts remitted to the
Trustee in respect of Compensating Interest. Such amounts so remitted shall be
included in the Available Funds and distributed therewith on the next
Distribution Date. The Servicer shall not be obligated to pay Compensating
Interest with respect to Prepayment Interest Shortfalls resulting from partial
Principal Prepayments or Relief Act Interest Shortfalls.

            Section 3.24 Obligations of the Servicer in Respect of Mortgage
Interest Rates and Monthly Payments.

            In the event that a shortfall in any collection on or liability with
respect to any Mortgage Loan results from or is attributable to adjustments to
Mortgage Interest Rates, Monthly Payments or 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 deliver to the Trustee for deposit in the
Distribution 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 3.24 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 3.25 Investment of Funds in the Collection Account and the
Distribution Account.

            (a) The Servicer may direct any depository institution maintaining
the Collection Account and the Trustee may direct any depository institution
maintaining the Distribution Account (for purposes of this Section 3.25, each an
"Investment Account"), to invest the funds in such Investment Account in one or
more Eligible 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, 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 an Affiliate of the Trustee. All such Eligible 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 or the Servicer, as
applicable (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) over each such
investment and the income thereon, 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 an Eligible Investment
payable on demand, the Trustee shall at the direction of the Servicer:

                  (x)   consistent with any notice required to be given
                        thereunder, demand that payment thereon be made on
                        the last day such Eligible 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 Eligible Investment would not
                        constitute an Eligible Investment in respect of funds
                        thereafter on deposit in the Investment Account.

            (b) All income and gain realized from the investment of funds in the
Collection Account shall be for the benefit of the Servicer. The Servicer shall
deposit in the Collection Account or (to the extent funds in the Escrow Account
are invested if permitted by applicable law) the Escrow Account, as applicable,
from its own funds the amount of any loss incurred in respect of any such
Eligible Investment made with funds in such account immediately upon realization
of such loss. All income and gain realized from the investment of funds in the
Distribution Account shall be for the benefit of the Trustee. The Trustee shall
deposit in the Distribution Account from its own funds the amount of any loss
incurred on Eligible Investments in the Distribution Account.

            (c) Except as otherwise expressly provided in this Agreement, if any
default occurs in the making of a payment due under any Eligible Investment, or
if a default occurs in any other performance required under any Eligible
Investment, the Trustee may and, subject to Section 8.01 and Section 8.02(a)(v),
upon the request of the NIMS Insurer or 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.

            The Trustee shall not in any way be held liable by reason of any
insufficiency in any Account held by the Trustee resulting from any investment
loss on any Eligible Investment included therein (except to the extent that the
Trustee is the obligor and has defaulted thereon).

            Section 3.26 Liability of Servicer; Indemnification.

            (a) Subject to clause (b) below and Section 6.03, the Servicer
(except the Trustee if it is required to succeed the Servicer hereunder)
indemnifies and holds the Trustee, the Depositor, the NIMS Insurer and the Trust
Fund harmless against any and all third party claims, losses, penalties, fines,
forfeitures, reasonable legal fees and related costs, judgments, and any other
costs, fees and expenses that the Trustee, the Depositor, the NIMS Insurer and
the Trust Fund 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
Servicing Standard. The Servicer shall immediately notify the Trustee, the NIMS
Insurer 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, including reasonable counsel fees, and promptly pay,
discharge and satisfy any judgment or decree which may be entered against the
Servicer, the Trustee, the Depositor, the NIMS Insurer and/or the Trust Fund in
respect of such claim. The provisions of this Section 3.26 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 Depositors, the NIMS Insurer or the
Servicer or any such Person against any breach of warranties or representations
made by such party herein, or against any specific liability imposed on the
Servicer for a breach of the Servicing Standard and/or this Agreement, or
against any liability which would otherwise be imposed by reason of its
respective willful misfeasance, bad faith, fraud or negligence in the
performance of its duties or by reasons of negligent disregard of its respective
obligations or duties hereunder.

            The Depositor, the NIMS Insurer, 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, prima facie, is
properly executed and submitted by any appropriate Person with respect to any
matters arising hereunder. The Depositor, the Servicer, the NIMS Insurer and any
director, officer, employee or agent of the Depositor, the Servicer or the NIMS
Insurer shall be indemnified and held harmless by the Trust against any loss,
liability or expense incurred in connection with any legal action relating to
this Agreement or the Certificates, other than any loss, liability or expense
incurred in connection with any legal action incurred by reason of its
respective misfeasance, bad faith, fraud or negligence, a breach of a
representation or warranty made by such party hereunder or (in the case of the
Servicer) a breach of the Servicing Standard in the performance of its
respective duties or by reason of negligent disregard of its respective
obligations or duties hereunder. Neither the Depositor, the NIMS Insurer, nor
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 expose it to any expense or liability;
provided, however, that the Depositor, the NIMS Insurer or the Servicer may in
their discretion undertake any action related to their obligations hereunder
which they 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. 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 3.27 Reports of Foreclosure and Abandonment of Mortgaged
Properties.

            Beginning in 20 , the Servicer shall file the reports of foreclosure
and abandonment of any Mortgaged Property required by Section 6050J of the Code
with the Internal Revenue Service on or before the due date for any such report.
Not later than 90 days following the end of each calendar year, beginning in 20
, the Servicer will deliver an Officer's Certificate to the Trustee and the NIMS
Insurer certifying its compliance with this Section 3.27. The reports from the
Servicer shall be in form and substance sufficient to meet the reporting
requirements imposed by such Section 6050J.

            Section 3.28 Protection of Assets.

            (a) Except for transactions and activities entered into in
connection with the securitization that is the subject of this Agreement, the
Trust is not authorized and has no power to:

            (1) borrow money or issue debt;

            (2) merge with another entity, reorganize, liquidate or sell
assets; or

            (3) engage in any business or activities.

            (b)  Each party to this Agreement agrees that it will not file an
involuntary bankruptcy petition against the Trustee or the Trust Fund or
initiate any other form of insolvency proceeding until after the Certificates
have been paid.

            Section 3.29 Limitation of Liability of the Credit Risk Manager.

            Neither the Credit Risk Manager, nor any of the directors, officers,
employees or agents of the Credit Risk Manager, shall be under any liability to
the Depositor, the Servicer, the Trustee or the Certificateholders for any
action taken or for refraining from the taking of any action in good faith
pursuant to this Agreement, 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 not protect the Credit Risk Manager
or any such person against liability that would otherwise be imposed by reason
of willful malfeasance, bad faith or negligence in its performance of its duties
or by reason of reckless disregard for its obligations and duties under this
Agreement or the applicable Credit Risk Management Agreement. 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 3.30 No Personal Solicitation.

            From and after the Closing Date, the Servicer agrees that it will
not take any action or permit or cause any action to be taken by any of its
agents and Affiliates, or by any independent contractors or independent mortgage
brokerage companies on the Servicer's behalf, to personally, by telephone, mail
or electronic mail, solicit the Mortgagor under any Mortgage Loan for the
purpose of refinancing such Mortgage Loan; provided, that the Servicer may
solicit any Mortgagor for whom the Servicer has received a request for
verification of mortgage, a request for demand for payoff, a mortgagor initiated
written or verbal communication indicating a desire to prepay the related
Mortgage Loan, or the mortgagor initiates a title search; provided further, it
is understood and agreed that promotions undertaken by the Servicer or any of
its Affiliates which (i) concern optional insurance products or other additional
products or (ii) are directed to the general public at large, including, without
limitation, mass mailings based on commercially acquired mailing lists,
newspaper, radio and television advertisements shall not constitute solicitation
under this Section, nor is the Servicer prohibited from responding to
unsolicited requests or inquiries made by a Mortgagor or an agent of a
Mortgagor. Furthermore, the Servicer shall be permitted to include in its
monthly statements to borrowers or otherwise, statements regarding the
availability of the Servicer's counseling services with respect to refinancing
mortgage loans.

            Section 3.31 Periodic Filings.

            (a) The Trustee and the Servicer shall reasonably cooperate with the
Depositor to enable the Depositor to satisfy its reporting requirements under
the Exchange Act and the parties hereto shall reasonably cooperate to enable the
Commission's requirements with respect to the Depositor to be met in the event
that the Commission issues additional interpretive guidelines or promulgates
rules or regulations, or in the event of any other change of law that would
require reporting arrangements or the allocation of responsibilities with
respect thereto, as described in this Section 3.31, to be conducted or allocated
in a different manner. Without limiting the generality of the foregoing, the
Trustee shall prepare on behalf of the Depositor any Current Reports on Form 8-K
(each, a "Form 8-K"), Distribution Reports on Form 10-D (each, a "Form 10-D")
and Annual Reports on Form 10-K (each, a "Form 10-K") as required by the
Exchange Act and the rules and regulations of the Commission thereunder, the
Depositor shall sign and the Trustee shall file (via the Commission's Electronic
Data Gathering and Retrieval System) such forms on behalf of the Depositor.
Notwithstanding the foregoing, the Depositor shall file the Form 8-Ks in
connection with the issuance of the Certificates.

            (b) Each Form 10-D shall be filed by the Trustee within 15 days
after each Distribution Date and shall include a copy of the Distribution Date
Statement for such Distribution Date as an exhibit thereto. In addition, the
Trustee shall include under Item 1 of each Form 10-D any information required by
Item 1121 of Regulation AB to the extent relevant that is not included on the
Distribution Date Statement. Any information in addition to the Distribution
Date Statement and any other information required by Item 1121 of Regulation AB
("Additional Form 10-D Information") shall be determined by the party preparing
such information as set forth on Exhibit R-1 hereto and the Trustee shall
compile such information pursuant to the following paragraph. The Trustee will
have no duty or liability for any failure hereunder to determine or prepare any
Additional Form 10-D Information, except as set forth in the Section 3.31(b).

            As set forth on Exhibit R-1 hereto, within five (5) calendar days
after the related Distribution Date, certain parties hereto shall be required to
provide to the Trustee and the Depositor, to the extent known by such parties,
any Additional Form 10-D Information, if applicable. The Depositor will be
responsible for all reasonable fees and expenses assessed or incurred by the
Trustee in connection with including any Additional Form 10-D Information on
Form 10-D pursuant to this paragraph, including converting any such disclosure
to an EDGAR-compatible format, other than such Additional Form 10-D Information
for which the Trustee is responsible as set forth on Exhibit R-1 hereto.

            After preparing the Form 10-D, the Trustee shall forward
electronically a draft copy of the Form 10-D to the Depositor for review. No
later than two (2) Business Days prior to the 15th calendar day after the
related Distribution Date, an officer of the Depositor shall indicate to the
Trustee the Depositor's consent to the form and substance of the draft Form 10-D
(which consent may be in electronic form). If a Form 10-D cannot be filed on
time or if a previously filed Form 10-D needs to be amended, the Trustee will
follow the procedures set forth in Section 3.31(e). Promptly (but no later than
one Business Day) after filing with the Commission, the Trustee will make
available on its internet website a final executed copy of each Form 10-D. The
Trustee shall have no liability for any loss, expense, damage or claim arising
out of or with respect to any failure to properly prepare and/or timely file
such Form 10-D, where such failure results from the Trustee's inability or
failure to obtain or receive, on a timely basis, any information from any party
hereto (other than the Trustee or any Servicing Function Participant utilized by
the Trustee) needed to prepare, arrange for execution or file such Form 10-D,
not resulting from its own negligence, bad faith or willful misconduct.

            (c) On or before 90 days after the end of each fiscal year of the
Trust (or such earlier date as may be required by the Exchange Act and the rules
and regulations of the Commission) commencing in 20 , the Trustee shall file a
Form 10-K, in form and substance as required by applicable law or applicable
Commission staff interpretations. Each such Form 10-K shall include the
following items, in each case to the extent they have been delivered to the
Trustee within the applicable time frames set forth in this Agreement: (i) an
annual compliance statement for the Trustee, the Servicer and each Additional
Servicer, as described under Section 3.19, (ii)(A) the annual reports on
assessment of compliance with Servicing Criteria for the Servicer, the Trustee
and each Servicing Function Participant, as described under Section 3.20, and
(B) if the Servicer's, the Trustee's or each Servicing Function Participant's
report on assessment of compliance with Servicing Criteria described under
Section 3.20 identifies any material instance of noncompliance or is not
included, disclosure identifying such instance of noncompliance or disclosure
that such report is not included and an explanation thereof, as the case may be,
(iii)(A) the registered public accounting firm attestation report for the
Servicer, the Trustee and each Servicing Function Participant, as described
under Section 3.20, and (B) if any registered public accounting firm attestation
report described under Section 3.20 identifies any material instance of
noncompliance or is not included, disclosure identifying such instance of
noncompliance or disclosure that such report is not included and an explanation
thereof, as the case may be, and (iv) a Certification as described in this
Section 3.31(c). Any disclosure or information in addition to (i) through (iv)
above that is required to be included on Form 10-K ("Additional Form 10-K
Information") shall be prepared by the party responsible for preparing such
information as set forth on Exhibit S hereto and the Trustee shall compile such
information pursuant to the following paragraph. The Trustee will have no duty
or liability for any failure hereunder to determine or prepare any Additional
Form 10-K Information, except to the extent of its obligations as set forth in
the next paragraph.

            As set forth on Exhibit R-2 hereto, no later than March 5th of each
year that the Trust is subject to the Exchange Act reporting requirements,
commencing in 20 , certain parties to this Agreement shall be required to
provide to the Trustee and the Depositor, to the extent known by such applicable
parties, any Additional Form 10-K Information. The Depositor will be responsible
for all reasonable fees and expenses assessed or incurred by the Trustee in
connection with including any Additional Form 10-D Information on Form 10-D
pursuant to this paragraph, including converting any such disclosure to an
EDGAR-compatible format, other than such Additional Form 10-D Information for
which the Trustee is responsible as set forth on Exhibit R-2 hereto.

            After preparing the Form 10-K, the Trustee shall forward
electronically a draft copy of the Form 10-K to the Depositor for review. No
later than the close of business on the second Business Day prior to the 10-K
Filing Deadline, the Depositor shall sign the Form 10-K and return an electronic
or fax copy of such signed Form 10-K, together with a signed copy of the
certification (the "Certification") attached hereto as Exhibit O and required to
be included with each Form 10-K pursuant to the Sarbanes-Oxley Act of 2002, as
amended (with an original executed hard copy of each to follow by overnight
mail) to the Trustee. If a Form 10-K cannot be filed on time or if a previously
filed Form 10-K needs to be amended, the Trustee will follow the procedures set
forth in Section 3.31(e). Promptly (but no later than one Business Day) after
filing with the Commission, the Trustee will make available on its internet
website a final executed copy of each Form 10-K. The Depositor and the Servicer
acknowledge that the performance by the Trustee of its duties under this Section
3.31(c) relating to the timely preparation and filing of Form 10-K is contingent
upon the Servicer, the Depositor, any Additional Servicer or Servicing Function
Participant and any other Person obligated to provide Additional Form 10-K
Information as set forth on Exhibit R-2 hereto, observing all applicable
deadlines in the performance of their duties under this Section 3.31(c), Section
3.19 and Section 3.20. The Trustee shall have no liability for any loss,
expense, damage, claim arising out of or with respect to any failure to properly
prepare and/or timely file such Form 10-K, where such failure results from the
Trustee's inability or failure to obtain or receive, on a timely basis, any
information from any party hereto (other than the Trustee or any Servicing
Function Participant utilized by the Trustee) needed to prepare, arrange for
execution or file such Form 10-K, not resulting from its own negligence, bad
faith or willful misconduct.

            In connection with the execution of the Certification, the Trustee
shall sign a certification (in the form attached hereto as Exhibit P-1, with
such changes as may be necessary or appropriate as a result of changes
promulgated by the Commission) for the benefit of the Depositor and its
officers, directors and Affiliates, and the Servicer shall sign a certification
(in the form attached hereto as Exhibit P-2, with such changes as may be
necessary or appropriate as a result of changes promulgated by the Commission)
for the benefit of the Depositor and its officers, directors and Affiliates.
Each such certification shall be delivered to the Depositor no later than March
5th of each year (or if such day is not a Business Day, the immediately
preceding Business Day). In the event that prior to the filing date of the Form
10-K in March of each year, the Trustee or the Servicer has actual knowledge of
information material to the Certification, that party shall promptly notify the
Depositor and each of the other parties signing the certifications referenced in
the preceding sentence. In addition, (i) the Trustee shall indemnify and hold
harmless the Depositor and the Sponsor and their officers, directors, employees,
agents 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 any breach of the
Trustee's obligations under Section 3.19, Section 3.20, Section 3.31 and Section
8.01 or the Trustee's material misstatement or omission, negligence, bad faith
or willful misconduct in connection therewith, and (ii) the Servicer shall
indemnify and hold harmless the Depositor and the Sponsor and their respective
officers, directors, employees, agents 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 any breach of the Servicer's obligations under Section 3.19, Section
3.20 and Section 3.31 or any material misstatement or omission, negligence, bad
faith or willful misconduct in connection therewith. If the indemnification
provided for herein is unavailable or insufficient to hold harmless any
indemnified party, then (i) the Trustee agrees in connection with a breach of
the Trustee's obligations under Section 3.19, Section 3.20, Section 3.31 and
Section 8.01 or the Trustee's material misstatement, omission, negligence, bad
faith or willful misconduct in connection therewith that it shall contribute to
the amount paid or payable by the Depositor and the Sponsor as a result of the
losses, claims, damages or liabilities of the Depositor and the Sponsor in such
proportion as is appropriate to reflect the relative fault of the Depositor and
the Sponsor on the one hand and the Trustee on the other and (ii) the Servicer
agrees in connection with a breach of the Servicer's obligations under Section
3.19, Section 3.20 and Section 3.31 or the Servicer's material misstatement,
omission, negligence, bad faith or willful misconduct in connection therewith
that it shall contribute to the amount paid or payable by the Depositor and the
Sponsor as a result of the losses, claims, damages or liabilities of the
Depositor and the Sponsor in such proportion as is appropriate to reflect the
relative fault of the Depositor and the Sponsor on the one hand and the Servicer
on the other.

            (d) Within four (4) Business Days after the occurrence of an event
requiring disclosure on Form 8-K (each such event, a "Reportable Event"), and
also if requested by the Depositor, the Trustee shall prepare and file on behalf
of the Trust any Form 8-K, as required by the Exchange Act, provided that the
Depositor shall file the initial Form 8-Ks in connection with the issuance of
the Certificates. Any disclosure or information related to a Reportable Event or
that is otherwise required to be included on Form 8-K (such information, "Form
8-K Information") shall be reported to the Depositor and the Trustee by the
parties set forth on Exhibit R-3 hereto and compiled by the Trustee pursuant to
the following paragraph. The Trustee will have no duty or liability for any
failure hereunder to determine or prepare any Form 8-K Information or any Form
8-K, except to the extent of its obligations as set forth in the next paragraph.

            As set forth on Exhibit R-3 hereto, for so long as the Trust is
subject to the Exchange Act reporting requirements, no later than 12:00 noon on
the second Business Day after the occurrence of a Reportable Event certain
parties to this Agreement shall be required to provide to the Depositor and the
Trustee, to the extent known by such applicable parties, any Form 8-K
Information, if applicable. The Depositor will be responsible for all reasonable
fees and expenses assessed or incurred by the Trustee in connection with
including any Form 8-K Information on Form 8-K pursuant to this paragraph,
including converting any such disclosure to an EDGAR-compatible format, other
than such Form 8-K Information for which the Trustee is responsible as set forth
on Exhibit R-3 hereto.

            After preparing the Form 8-K, the Trustee shall forward
electronically a draft copy of the Form 8-K to the Depositor for review,
verification and execution by the Depositor. No later than 12:00 noon on the
fourth Business Day after the Reportable Event, an officer of the Depositor
shall sign the Form 8-K and return an electronic or fax copy of such signed Form
8-K (with an original executed hard copy to follow by overnight mail) to the
Trustee. Promptly (but no later than one Business Day) after filing with the
Commission, the Trustee will, make available on its internet website a final
executed copy of each Form 8-K filed by it. If a Form 8-K cannot be filed on
time or if a previously filed Form 8-K needs to be amended, the Trustee will
follow the procedures set forth in Section 3.31(e). The Depositor acknowledges
that the performance by the Trustee of its duties under this Section 3.31(d)
related to the timely preparation and filing of Form 8-K is contingent upon the
parties to this Agreement and any other Person obligated to provide Form 8-K
Information as set forth on Exhibit R-3 hereto, observing all applicable
deadlines in the performance of their duties under this Section 3.31(d). The
Trustee shall have no liability for any loss, expense, damage or claim arising
out of or with respect to any failure to properly prepare and/or timely file
such Form 8-K, where such failure results from the Trustee's inability or
failure to obtain or receive, on a timely basis, any information from any party
hereto (other than the Trustee or any Servicing Function Participant utilized by
the Trustee) needed to prepare, arrange for execution or file such Form 8-K, not
resulting from its own negligence, bad faith or willful misconduct.

            (e) In the event that the Trustee is unable to timely file with the
Commission all or any required portion of any Form 8-K, Form 10-D or Form 10-K
required to be filed by this Agreement because required information was either
not delivered to it or delivered to it after the delivery deadlines set forth in
this Agreement or for any other reason, the Trustee will immediately notify the
Depositor by telephone. In the case of Form 10-D and Form 10-K, the Depositor,
Servicer and Trustee will cooperate to prepare and file a Form 12b-25 pursuant
to Rule 12b-25 of the Exchange Act. In the case of Form 8-K, the Trustee will,
upon receipt of all information required to be included on Form 8-K, file such
Form 8-K. Within 5 calendar days following the original due date of the Form
10-D, the Trustee shall prepare and file the related Form 10-D. Within 15
calendar days following the original due date of the Form 10-K, the Trustee
shall prepare and file the related Form 10-K. In the event that any previously
filed Form 8-K, Form 10-D or Form 10-K needs to be amended, the party to this
Agreement deciding that an amendment to such Form 8-K, Form 10-D or Form 10-K is
required will notify the Depositor, the Trustee and the Servicer and such
parties will cooperate to prepare any necessary Form 8-K/A, Form 10-D/A or Form
10-K/A. Any Form 12b-25 or any amendment to Form 8-K, Form 10-D or Form 10-K
shall be signed by the Depositor. The Depositor and Servicer acknowledge that
the performance by the Trustee of its duties under this Section 3.31(e) related
to the timely preparation and filing of a Form 12b-25 or any amendment to Form
8-K, Form 10-D or Form 10-K is contingent upon the Servicer and the Depositor
performing their duties under this Section. The Trustee shall have no liability
for any loss, expense, damage, claim arising out of or with respect to any
failure to properly prepare and/or timely file any such Form 12b-25 or any
amendments to Form 8-K, Form 10-D or Form 10-K, where such failure results from
the Trustee's inability or failure to obtain or receive, on a timely basis, any
information from any other party hereto (other than the Trustee or any Servicing
Function Participant utilized by the Trustee) needed to prepare, arrange for
execution or file such Form 12b-25 or any amendments to Form 8-K, Form 10-D or
Form 10-K, not resulting from its own negligence, bad faith or willful
misconduct.

            (f) Upon any filing with the Commission, the Trustee shall promptly
deliver to the Depositor a copy of any such executed report, statement or
information.

            (g) The obligations set forth in paragraphs (a) through (f) of this
Section shall only apply with respect to periods for which the Trustee is
obligated to file reports on Form 8-K, 10-D or 10-K. Unless otherwise instructed
by the Depositor, prior to January 30th of the first year in which the Trustee
is permitted to do so under Section 15(d) of the Exchange Act and other
applicable law and regulations, the Trustee shall prepare, the Depositor shall
execute, and the Trustee shall file with the Commission a Form 15 Suspension
Notification with respect to the Trust, with a copy to the Depositor. At any
time after the filing of a Form 15 Suspension Notification, if the number of
Certificateholders of record exceeds the number set forth in Section 15(d) of
the Exchange Act or the regulations promulgated pursuant thereto which would
cause the Trust to again become subject to the reporting requirements of the
Exchange Act, the Trustee shall recommence preparing and filing reports on Form
10-D, Form 10-K and, if applicable, Form 8-K, as required pursuant to this
Section and the parties hereto will again have the obligations set forth in
paragraphs (a) through (f) of this Section.

            (d) For all purposes of this Agreement, with respect to any Mortgage
Loan, delinquencies shall be determined and reported based on the so-called
"OTS" methodology for determining delinquencies on mortgage loans similar to the
Mortgage Loans. By way of example, a Mortgage Loan would be one payment
delinquent with respect to a Monthly Payment due on a Due Date if such Monthly
Payment is not made by the close of business on the Mortgage Loan's next
succeeding Due Date, and a Mortgage Loan would be two payments delinquent with
respect to such Monthly Payment if such Monthly Payment were not made by the
close of business on the Mortgage Loan's second succeeding Due Date. The
Servicer hereby represents and warrants to the Depositor that this delinquency
recognition policy is its current policy and is not less restrictive than any
delinquency recognition policy established by the primary safety and soundness
regulator, if any, of the Servicer.

            Section 4.07 Remittance Reports; Advances.

            (a) On the second Business Day following each Determination Date but
in no event later than the 20th day of each month (or if such 20th day is not a
Business Day, the preceding Business Day), the Servicer shall deliver to the
Depositor, the Trustee and the NIMS Insurer by telecopy (or by such other means
as the Servicer, the NIMS Insurer and the Trustee may agree from time to time) a
Remittance Report with respect to the related Distribution Date. On the same
date, the Servicer shall electronically forward to the Depositor and the Trustee
in such medium as may be agreed among the Servicer, the Trustee and the
Depositor the information set forth in such Remittance Report with respect to
the related Distribution Date, such information reasonably available to the
Servicer necessary in order for the Trustee to perform the calculations
necessary to make the distributions and allocations contemplated by Section
4.01, 4.02 and 4.03 and to prepare the Distribution Date Statement and such
information as shall be reasonably requested by the Depositor to enable the
Depositor to disclose "static pool information," as required by Item 1105 of
Regulation AB, with respect to the Mortgage Loans. 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 4.07(d), the sum of (i) the
aggregate amount of Monthly Payments (net of the related Servicing Fee), due
during the related Collection 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
Collection Period and as to which REO Property an REO Disposition did not occur
during the related Collection Period, an amount equal to the excess, if any, of
the REO Imputed Interest on such REO Property for such Collection Period, over
the net income from such REO Property transferred to the Distribution Account
pursuant to Section 3.13 for distribution on such Distribution Date.

            On or before 1:00 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 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 the
Collection Account that amounts held for future distribution have been, as
permitted by this Section 4.07, 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. Any amounts held for future distribution and so used 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 and 4.02 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 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
earlier of such time as the Trust acquires title to the related Mortgaged
Property or such Mortgage Loan is paid in full by the Mortgagor or disposed of
by the Trust, or until the recovery of all Liquidation Proceeds 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 would, if made, constitute a Nonrecoverable Advance. The determination
by the Servicer that it has made a Nonrecoverable Advance or that any proposed
Advance, if made, would constitute a Nonrecoverable Advance, shall be evidenced
by an Officers' Certificate of the Servicer delivered to the Depositor, the NIMS
Insurer and the Trustee. The Trustee shall be entitled to conclusively rely upon
any such determination by the Servicer.

            Section 4.08 REMIC Distributions.

            (a) On each Distribution Date, the Trustee shall cause in the
following order of priority, the following amounts to be distributed by REMIC 1
to REMIC 2 on account of the REMIC 1 Regular Interests or withdrawn from the
Distribution Account and distributed to the Holders of the Class R Certificates

      Interest LT1ZZ, pro rata, in an amount equal to (A) the Uncertificated

      respect thereof remaining unpaid from previous Distribution Dates. Amounts
      payable as Uncertificated Accrued Interest in respect of REMIC 1 Regular
      Interest LT1ZZ shall be reduced and deferred when the REMIC 1
      Overcollateralized Amount is less than the REMIC 1 Overcollateralization
      Target Amount, by the lesser of (x) the amount of such difference and (y)
      the Maximum LT1ZZ Uncertificated Accrued Interest Deferral Amount and such
      amount will be payable to the Holders of REMIC 1 Regular Interest LT1A1,
      REMIC 1 Regular Interest LT1A2, REMIC 1 Regular Interest LT1A3, REMIC 1
      Regular Interest LT1A4, REMIC 1 Regular Interest LT1M1, REMIC 1 Regular

      REMIC 1 Regular Interest LT1M7 in the same proportion as the
      Overcollateralization Deficiency is allocated to the Corresponding
      Certificates;

            (ii) to Holders of REMIC 1 Regular Interest LT1SUB, REMIC 1 Regular
      Interest LT1GRP, REMIC 1 Regular Interest LT2SUB, REMIC 1 Regular Interest
      LT2GRP and REMIC 1 Regular Interest LT1XX, pro rata, in an amount equal to

      Distribution Dates;

            (iii) to the Holders of REMIC 1 Regular Interests, in an amount
      equal to the remainder of the REMIC 1 Marker Allocation Percentage of
      Available Funds for such Distribution Date after the distributions made
      pursuant to clause (i) above, allocated as follows:

                        (1) to REMIC 1 Regular Interest LT1AA, 98.00% of such
                  remainder, until the Uncertificated Principal Balance of such
                  Uncertificated REMIC 1 Regular Interest is reduced to zero;

                        (2) to REMIC 1 Regular Interest LT1A1, REMIC 1 Regular

                  REMIC 1 Regular Interest LT1M4, REMIC 1 Regular Interest
                  LT1M5, REMIC 1 Regular Interest LT1M6 and REMIC 1 Regular
                  Interest LT1M7, 1.00% of such remainder, in the same
                  proportion as principal payments are allocated to the
                  Corresponding Certificates, until the Uncertificated Principal
                  Balances of such REMIC 1 Regular Interests are reduced to
                  zero; then

                        (3) to REMIC 1 Regular Interest LT1ZZ, 1.00% of such
                  remainder, until the Uncertificated Principal Balance of such
                  REMIC 1 Regular Interest is reduced to zero;

                  provided, however, that (i) 98.00% and (ii) 2.00% of any

                  (i) REMIC 1 Regular Interest LT1AA and (ii) REMIC 1 Regular
                  Interest LT1ZZ, respectively; and

            (iv) to the Holders of REMIC 1 Regular Interests, in an amount equal
      to the REMIC 1 Sub WAC Allocation Percentage of Available Funds for such
      Distribution Date after the distributions made pursuant to clause (i)
      above, such that distributions of principal shall be deemed to be made to
      the REMIC 1 Regular Interests first, so as to keep the Uncertificated
      Principal Balance of each REMIC 1 Regular Interest ending with the
      designation "GRP" equal to 0.01% of the aggregate Principal Balance of the
      Mortgage Loans in the related group of Mortgage Loans; second, to each
      REMIC 1 Regular Interest ending with the designation "SUB," so that the
      Uncertificated Principal Balance of each such REMIC 1 Regular Interest is
      equal to 0.01% of the excess of (x) the aggregate Principal Balance of the
      Mortgage Loans in the related group of Mortgage Loans over (y) the
      aggregate current Certificate Principal Balance of the Class A
      Certificates in the related group of Mortgage Loans (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 1 Regular
      Interests such that the REMIC 1 Subordinated Balance Ratio is maintained);
      and third, any remaining principal to REMIC 1 Regular Interest LT1XX.

            (b) The Trustee shall cause the following allocation of losses:

            (i) The REMIC 1 Marker Allocation Percentage of the aggregate amount
      of any Prepayment Interest Shortfalls and the REMIC 1 Marker Allocation

      be allocated first, to Uncertificated Accrued Interest payable to REMIC 1
      Regular Interest LT1AA and REMIC 1 Regular Interest LT1ZZ up to an
      aggregate amount equal to the REMIC 1 Interest Loss Allocation Amount, 98%
      and 2%, respectively, and thereafter among REMIC 1 Regular Interest LT1AA,
      REMIC 1 Regular Interest LT1A1, REMIC 1 Regular Interest LT1A2, REMIC 1
      Regular Interest LT1A3, REMIC 1 Regular Interest LT1A4, REMIC 1 Regular
      Interest LT1M1, REMIC 1 Regular Interest LT1M2, REMIC 1 Regular Interest
      LT1M3, REMIC 1 Regular Interest LT1M4, REMIC 1 Regular Interest LT1M5,

      Regular Interest LT1ZZ pro rata based on, and to the extent of, one
      month's interest at the then applicable respective Uncertificated REMIC 1
      Pass-Through Rate on the respective Uncertificated Principal Balance of
      each such REMIC 1 Regular Interest;

            (ii) The REMIC 1 Sub WAC Allocation Percentage of the aggregate
      amount of any Prepayment Interest Shortfalls and the REMIC 1 Sub WAC

      Date shall be allocated first, to Uncertificated Accrued Interest payable
      to REMIC 1 Regular Interest LT1SUB, REMIC 1 Regular Interest LT1GRP, REMIC
      1 Regular Interest LT2SUB, REMIC 1 Regular Interest LT2GRP and REMIC 1
      Regular Interest LT1XX, pro rata based on, and to the extent of, one
      month's interest at the then applicable respective Uncertificated REMIC 1
      Pass-Through Rate on the respective Uncertificated Principal Balance of
      each such REMIC 1 Regular Interest;

            (iii) The REMIC 1 Marker Allocation Percentage of all Realized
      Losses on the Mortgage Loans shall be allocated by the Trustee on each
      Distribution Date to the following REMIC 1 Regular Interests in the
      specified percentages, as follows: first, to Uncertificated Accrued
      Interest payable to REMIC 1 Regular Interest LT1AA and REMIC 1 Regular
      Interest LT1ZZ up to an aggregate amount equal to the REMIC 1 Interest
      Loss Allocation Amount, 98% and 2%, respectively; second, to the
      Uncertificated Principal Balances of REMIC 1 Regular Interest LT1AA and
      REMIC 1 Regular Interest LT1ZZ up to an aggregate amount equal to the

      Uncertificated Principal Balances of REMIC 1 Regular Interest LT1AA, REMIC
      1 Regular Interest LT1M6 and REMIC 1 Regular Interest LT1ZZ, 98%, 1% and

      Uncertificated Principal Balances of REMIC 1 Regular Interest LT1AA, REMIC
      1 Regular Interest LT1M4 and REMIC 1 Regular Interest LT1ZZ, 98%, 1% and
      1%, respectively, until the Uncertificated Principal Balance of REMIC 1
      Regular Interest LT1M4 has been reduced to zero; seventh to the
      Uncertificated Principal Balances of REMIC 1 Regular Interest LT1AA, REMIC
      1 Regular Interest LT1M3 and REMIC 1 Regular Interest LT1ZZ, 98%, 1% and
      1%, respectively, until the Uncertificated Principal Balance of REMIC 1
      Regular Interest LT1M3 has been reduced to zero; eighth, to the
      Uncertificated Principal Balances of REMIC 1 Regular Interest LT1AA, REMIC

      Distribution Date first, so as to keep the Uncertificated Principal
      Balance of each REMIC 1 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 1 Regular Interest
      ending with the designation "SUB," so that the Uncertificated Principal
      Balance of each such REMIC 1 Regular Interest is equal to 0.01% of the
      excess of (x) the aggregate Principal Balance of the Mortgage Loans in the
      related Loan Group over (y) the aggregate current Certificate Principal
      Balances of the Class A Certificates in the related group of Mortgage
      Loans (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 1 Regular Interests such that the REMIC 1
      Subordinated Balance Ratio is maintained); and third, any remaining
      Realized Losses shall be allocated to REMIC 1 Regular Interest LT1XX.

            (c) With respect to REMIC 1, any increase in principal balance due

Interest LT1XX; 49% to REMIC 1 Regular Interest LT1AA; 0.5% to REMIC 1 Regular
Interest LT1ZZ; and 0.5% to each REMIC 1 Regular Interest that is a
Corresponding Class to any REMIC 2 Regular Interest that was increased as a
result of such Subsequent Recovery (provided, that if more than one REMIC 2
Regular Interest is so increased, such amount shall be allocated to the REMIC 1
Regular Interests that are Corresponding Classes in the same proportion as the
increase is allocated to the applicable REMIC 2 Regular Interests).

            (d) Notwithstanding anything to the contrary contained herein, the
above distributions in this Section 4.08 (other than on the Certificates) are
deemed distributions, and distributions of funds from the Distribution Account
shall be made only in accordance with Sections 4.01 and 4.02 hereof.

                                   ARTICLE V

                                THE CERTIFICATES

            Section 5.01 The Certificates.

            Each of the Class A-1, Class A-2, Class A-3, Class A-4, Class M-1,
Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class CE,
Class P, Class R and Class R-X Certificates shall be substantially in the forms
annexed hereto as exhibits, and shall, on original issue, be executed by the
Trustee and authenticated and delivered by the Certificate Registrar to or upon
the receipt of a Written Order to Authenticate from the Depositor concurrently
with the sale and assignment to the Trustee of the Trust Fund. Each Class of the
Offered Certificates and the Class M-7 Certificates shall be initially evidenced
by one or more Certificates representing a Percentage Interest with a minimum
dollar denomination of $25,000 and integral multiples of $1 in excess thereof.
The Class CE and Class P Certificates are issuable only in minimum Percentage
Interests of 10%. The Class R and Class R-X Certificates are each issuable only
as a single certificate.

            The Certificates shall be executed on behalf of the Trust by manual
or facsimile signature on behalf of the Trustee by a Responsible Officer.
Certificates bearing the manual or facsimile signatures of individuals who were,
at the time when such signatures were affixed, authorized to sign on behalf of
the Trustee shall bind the Trust, notwithstanding that such individuals or any
of them have ceased to be so authorized prior to the authentication and delivery
of such Certificates or did not hold such offices at the date of such
Certificate. No Certificate shall be entitled to any benefit under this
Agreement or be valid for any purpose, unless such Certificate shall have been
manually authenticated by the Certificate Registrar substantially in the form
provided for herein, and such authentication upon any Certificate shall be
conclusive evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication. Subject to Section 5.02(c), the Offered Certificates
and the Class M-7 Certificates shall be Book-Entry Certificates. The Class CE,
Class P, Class R and Class R-X Certificates shall not be Book-Entry Certificates
but shall be issued in fully registered certificate form.

            Section 5.02 Registration of Transfer and Exchange of Certificates.

            (a) The Certificate Registrar shall cause to be kept at the
Corporate Trust Office of the Trustee a Certificate Register in which, subject
to such reasonable regulations as it may prescribe, the Certificate Registrar
shall provide for the registration of Certificates and of transfers and
exchanges of Certificates as herein provided. The Trustee shall initially serve
as Certificate Registrar for the purpose of registering Certificates and
transfers and exchanges of Certificates as herein provided. The Trustee as
Certificate Registrar shall be subject to the same standards of care,
limitations on liability and rights to indemnity as the Trustee, and the
provisions of Sections 8.01, 8.02, 8.03, 8.04, 8.05, 8.14 and 8.15 shall apply
to the Certificate Registrar to the same extent as they apply to the Trustee.
Any Certificate Registrar appointed in accordance with this Section 5.02(a) may
at any time resign by giving at least 30 days' advance written notice of
resignation to the Trustee, the Servicer and the Depositor, such resignation to
become effective upon appointment of a successor Certificate Registrar.

            Upon surrender for registration of transfer of any Certificate at
any office or agency of the Certificate Registrar maintained for such purpose
pursuant to the foregoing paragraph and, in the case of the Class R and Class
R-X Certificates, upon satisfaction of the conditions set forth below, the
Trustee on behalf of the Trust shall execute and the Certificate Registrar shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of the same aggregate Percentage
Interest.

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

            (b) Upon original issuance, the Book-Entry Certificates shall be
issued in the form of one or more typewritten certificates, to be delivered to
the Depository, the initial Depository, by, or on behalf of, the Depositor; or
to, and deposited with the Certificate Custodian, on behalf of the Depository,
if directed to do so pursuant to instructions from the Depository. Except as
provided in paragraph (c) below, the Book-Entry Certificates shall at all times
remain registered in the name of the Depository or its nominee and at all times:
(i) registration of such Certificates may not be transferred by the Trustee
except to another Depository; (ii) the Depository shall maintain book-entry
records with respect to the Certificate Owners and with respect to ownership and
transfers of such Certificates; (iii) ownership and transfers of registration of
such Certificates on the books of the Depository shall be governed by applicable
rules established by the Depository; (iv) the Depository may collect its usual
and customary fees, charges and expenses from its Depository Participants; (v)
the Trustee shall for all purposes deal with the Depository as representative of
the Certificate Owners of the Certificates for purposes of exercising the rights
of Holders under this Agreement, and requests and directions for and votes of
such representative shall not be deemed to be inconsistent if they are made with
respect to different Certificate Owners; (vi) the Trustee may rely and shall be
fully protected in relying upon information furnished by the Depository with
respect to its Depository Participants and furnished by the Depository
Participants with respect to indirect participating firms and Persons shown on
the books of such indirect participating firms as direct or indirect Certificate
Owners; and (vii) the direct participants of the Depository shall have no rights
under this Agreement under or with respect to any of the Certificates held on
their behalf by the Depository, and the Depository may be treated by the Trustee
and its agents, employees, officers and directors as the absolute owner of the
Certificates for all purposes whatsoever.

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

            (c) If the Depository advises the Trustee in writing that the
Depository is no longer willing or able to discharge properly its
responsibilities as Depository and the Trustee or the Depositor is unable to
locate a qualified successor. Upon surrender to the Certificate Registrar of the
Book-Entry Certificates by the Depository, accompanied by registration
instructions from the Depository for registration, the Trustee shall, at the
Trust's expense, execute on behalf of the Trust and the Certificate Registrar
shall authenticate definitive, fully registered certificates (the "Definitive
Certificates"). None of the Depositor or the Trustee shall be liable for any
delay in delivery of such instructions and may conclusively rely on, and shall
be protected in relying on, such instructions. Upon the issuance of Definitive
Certificates, the Trustee, the Certificate Registrar, the Servicer, any Paying
Agent and the Depositor shall recognize the Holders of the Definitive
Certificates as Certificateholders hereunder.

            (d) Except with respect to a transfer of the Private Certificates
between or among the Depositor, the Seller, their affiliates or both, no
transfer, sale, pledge or other disposition of any Private Certificate shall be
made unless such disposition is exempt from the registration requirements of the
Securities Act of 1933, as amended (the "1933 Act"), and any applicable state
securities laws or is made in accordance with the 1933 Act and laws. In the
event of any such transfer, (i) unless such transfer is made in reliance upon
Rule 144A (as evidenced by the investment letter delivered to the Certificate
Registrar, in substantially the form attached hereto as Exhibit J-2) under the
1933 Act, the Certificate Registrar and the Depositor shall require a written
Opinion of Counsel (which may be in-house counsel) acceptable to and in form and
substance reasonably satisfactory to the Certificate Registrar and the Depositor
that such transfer may be made pursuant to an exemption, describing the
applicable exemption and the basis therefor, from the 1933 Act or is being made
pursuant to the 1933 Act, which Opinion of Counsel shall not be an expense of
the Certificate Registrar or the Depositor or (ii) the Certificate Registrar
shall require the transferor to execute a transferor certificate (in
substantially the form attached hereto as Exhibit L) and the transferee to
execute an investment letter (in substantially the form attached hereto as
Exhibit J-1 or J-2 (in the case of the Class P, Class CE, Class R or Class R-X
Certificate) or in the form of Exhibit J-2 (in the case of Class M-7
Certificates)) acceptable to and in form and substance reasonably satisfactory
to the Depositor and the Certificate Registrar certifying to the Depositor and
the Certificate Registrar the facts surrounding such transfer, which investment
letter shall not be an expense of the Certificate Registrar or the Depositor.
The Holder of a Private Certificate desiring to effect such transfer shall, and
does hereby agree to, indemnify the Certificate Registrar and the Depositor
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. For purposes of clause (ii)
of this Section 5.02(d) the representations required in any transferor
certificate (substantially in the form of Exhibit L hereto) and any investment
letter (substantially in the form of Exhibit J-2 hereto) shall be deemed to have
made in connection with the transfer of any Private Certificate that is a
Book-Entry Certificate.

            No transfer of an ERISA-Restricted Certificate shall be made unless
the Certificate Registrar shall have received either (i) a representation from
the transferee of such Certificate, acceptable to and in form and substance
satisfactory to the Certificate Registrar and the Depositor (such requirement is
satisfied only by the Certificate Registrar's receipt of a representation letter
from the transferee substantially in the form of Exhibit I hereto, as
appropriate), to the effect that such transferee is not an employee benefit plan
or arrangement subject to Section 406 of ERISA, a plan subject to Section 4975
of the Code or a plan subject to any federal, state or local law ("Similar Law")
materially similar to the foregoing provisions of ERISA or the Code, nor a
person acting on behalf of any such plan or arrangement nor using the assets of
any such plan or arrangement to effect such transfer or (ii) (except in the case
of the Class R and Class R-X Certificates) in the case of any such ERISA
Restricted Certificate presented for registration in the name of an employee
benefit plan subject to ERISA or a plan or arrangement subject to Section 4975
of the Code (or comparable provisions of any subsequent enactments), or a
trustee of any such plan or any other person acting on behalf of any such plan
or arrangement or using such plan's or arrangement's assets, an Opinion of
Counsel satisfactory to the Certificate Registrar, to the effect that the
purchase or holding of such ERISA Restricted Certificate will not constitute or
result in a non-exempt prohibited transaction within the meaning of ERISA,
Section 4975 of the Code or Similar Law and will not subject the Depositor, the
Servicer, the Trustee, the NIMS Insurer or the Certificate Registrar to any
obligation in addition to those expressly undertaken in this Agreement or to any
liability. For purposes of clause (i) of the preceding sentence, such
representation shall be deemed to have been made to the Certificate Registrar by
the acceptance by a Certificate Owner of the beneficial interest in any such
Class of ERISA-Restricted Certificates, unless the Certificate Registrar shall
have received from the transferee an alternative representation acceptable in
form and substance to the Depositor. Notwithstanding anything else to the
contrary herein, any purported transfer of an ERISA-Restricted Certificate to or
on behalf of an employee benefit plan subject to ERISA, Section 4975 of the Code
or Similar Law without the delivery to the Certificate Registrar of an Opinion
of Counsel satisfactory to the Certificate Registrar as described above shall be
void and of no effect.

            Each Person who has or who acquires any Ownership Interest in the
Class R or Class R-X 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 appointed the Depositor or its
designee as its attorney-in-fact to negotiate the terms of any mandatory sale
under clause (v) below and to execute all instruments of transfer and to do all
other things necessary in connection with any such sale, and the rights of each
Person acquiring any Ownership Interest in the Class R or Class R-X Certificate
are expressly subject to the following provisions:

            (i) Each Person holding or acquiring any Ownership Interest in the
      Class R or Class R-X Certificate shall be a Permitted Transferee and shall
      promptly notify the Certificate Registrar of any change or impending
      change in its status as a Permitted Transferee.

            (ii) No Person shall acquire an Ownership Interest in the Class R or
      Class R-X Certificate unless such Ownership Interest is a pro rata
      undivided interest.

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

            A. an affidavit in the form of Exhibit K hereto from the proposed
transferee to the effect that, among other things, such transferee is a
Permitted Transferee and that it is not acquiring its Ownership Interest in the
Class R or Class R-X Certificate that is the subject of the proposed transfer as
a nominee, trustee or agent for any Person who is not a Permitted Transferee;
and

            B. a covenant of the proposed transferee to the effect that the
proposed transferee agrees to be bound by and to abide by the transfer
restrictions applicable to the Class R or Class R-X Certificate.

            (iv) Any attempted or purported transfer of any Ownership Interest
      in the Class R or Class R-X Certificate in violation of the provisions of
      this Section shall be absolutely null and void and shall vest no rights in
      the purported transferee. If any purported transferee shall, in violation
      of the provisions of this Section, become the Holder of the Class R
      Certificate, then the prior Holder of such Class R or Class R-X
      Certificate that is a Permitted Transferee shall, upon discovery that the
      registration of transfer of such Class R or Class R-X Certificate was not
      in fact permitted by this Section, be restored to all rights as Holder
      thereof retroactive to the date of registration of transfer of such Class
      R or Class R-X Certificate. The Certificate Registrar shall be under no
      liability to any Person for any registration of transfer of the Class R or
      Class R-X Certificate that is in fact not permitted by this Section or for
      making any distributions due on such Class R or Class R-X Certificate to
      the Holder thereof or taking any other action with respect to such Holder
      under the provisions of this Agreement so long as the Certificate
      Registrar received the documents specified in clause (iii). The Trustee
      shall be entitled to recover from any Holder of the Class R or Class R-X
      Certificate that was in fact not a Permitted Transferee at the time such
      distributions were made all distributions made on such Class R or Class
      R-X Certificate. Any such distributions so recovered by the Trustee shall
      be distributed and delivered by the Trustee to the prior Holder of such
      Class R or Class R-X Certificate that is a Permitted Transferee.

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

            (vi) If any Person other than a Permitted Transferee acquires any
      Ownership Interest in the Class R or Class R-X Certificate in violation of
      the restrictions in this Section, then the Trustee will provide to the
      Internal Revenue Service, and to the persons specified in Sections
      860E(e)(3) and (6) of the Code, information needed to compute the tax
      imposed under Section 860E(e)(5) of the Code on transfers of residual
      interests to disqualified organizations. The Trustee shall be entitled to
      reasonable compensation for providing such information from the person to
      whom it is provided.

The foregoing provisions of this Section shall cease to apply to transfers
occurring on or after the date on which there shall have been delivered to
the Certificate Registrar, in form and substance satisfactory to the
Certificate Registrar, (i) written notification from each Rating Agency that
the removal of the restrictions on Transfer set forth in this Section will
not cause such Rating Agency to downgrade its rating of the Certificates and
(ii) an Opinion of Counsel to the effect that such removal will not cause any
REMIC created hereunder to fail to qualify as a REMIC.

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

            All Certificates surrendered for registration of transfer or
exchange shall be cancelled by the Certificate Registrar and disposed of
pursuant to its standard procedures.

            Section 5.03 Mutilated, Destroyed, Lost or Stolen Certificates.

            If (i) any mutilated Certificate is surrendered to the Certificate
Registrar or the Certificate Registrar receives evidence to its satisfaction of
the destruction, loss or theft of any Certificate and (ii) there is delivered to
the Trustee, the Depositor, the NIMS Insurer and the Certificate Registrar such
security or indemnity as may be required by them to save each of them harmless,
then, in the absence of notice to the Trustee or the Certificate Registrar that
such Certificate has been acquired by a bona fide purchaser, the Trustee shall
execute on behalf of the Trust, and the Certificate Registrar shall authenticate
and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Certificate, a new Certificate of like tenor and Percentage Interest.
Upon the issuance of any new Certificate under this Section, the Trustee or the
Certificate Registrar may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any
other expenses (including the fees and expenses of the Trustee and the
Certificate Registrar) in connection therewith. Any duplicate Certificate issued
pursuant to this Section, shall constitute complete and indefeasible evidence of
ownership in the Trust, 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 Servicer, the Depositor, the NIMS Insurer, the Trustee, the
Certificate Registrar, any Paying Agent and any agent of the Servicer, the
Depositor, the NIMS Insurer, the Certificate Registrar, any Paying Agent or the
Trustee may treat the Person, including a Depository, 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 4.02 and for all other
purposes whatsoever, and none of the Servicer, the Trust, the NIMS Insurer, the
Trustee nor any agent of any of them shall be affected by notice to the
contrary.

            Section 5.05 Appointment of Paying Agent.

            The Paying Agent shall make distributions to Certificateholders from
the Distribution Account pursuant to Section 4.01 and 4.02 and shall report the
amounts of such distributions to the Trustee. The duties of the Paying Agent may
include the obligation to distribute statements and provide information to
Certificateholders as required hereunder. The Paying Agent hereunder shall at
all times be an entity duly incorporated and validly existing under the laws of
the United States of America or any state thereof, authorized under such laws to
exercise corporate trust powers and subject to supervision or examination by
federal or state authorities. The Paying Agent shall initially be the Trustee.
The Trustee may appoint a successor to act as Paying Agent, which appointment
shall be reasonably satisfactory to the Depositor, the NIMS Insurer and the
Rating Agencies. The Trustee as Paying Agent shall be subject to the same
standards of care, limitations on liability and rights to indemnity as the
Trustee, and the provisions of Sections 8.01, 8.02, 8.03, 8.04, 8.05, 8.14, 8.15
and 8.16 shall apply to the Paying Agent to the same extent as they apply to the
Trustee. Any Paying Agent appointed in accordance with this Section 5.05 may at
any time resign by giving at least 30 days' advance written notice of
resignation to the Trustee, the Servicer, the NIMS Insurer and the Depositor,
such resignation to become effective upon appointment of a successor Paying
Agent.

                                   ARTICLE VI

                         THE SERVICER AND THE DEPOSITOR

            Section 6.01 Liability of the Servicer and the Depositor.

            The Servicer shall be liable in accordance herewith only to the
extent of the obligations specifically imposed upon and undertaken by the
Servicer herein. The Depositor shall be liable in accordance herewith only to
the extent of the obligations specifically imposed upon and undertaken by the
Depositor.

            Section 6.02 Merger or Consolidation of, or Assumption of the
Obligations of, the Servicer or the Depositor.

            Any entity into which the Servicer or the Depositor may be merged or
consolidated, or any entity resulting from any merger, conversion or
consolidation to which the Servicer or the Depositor shall be a party, or any
corporation succeeding to the business of the Servicer or the Depositor, shall
be the successor of the Servicer or the Depositor, 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 (a) the successor servicer shall
satisfy all the requirements of Section 7.02 with respect to the qualifications
of a successor servicer and (b) the Servicer shall provide to the Depositor, at
least 15 calendar days prior to the effective date of such succession or
appointment, (x) written notice to the Depositor of such succession or
appointment and (y) in writing and in form and substance reasonably satisfactory
to the Depositor, all information reasonably necessary to enable the Trustee,
pursuant to Section 3.31(d), to accurately and timely report the event under
Item 6.02 of Form 8-K pursuant to the Exchange Act (if such reports under the
Exchange Act are then required to be filed under the Exchange Act).

            Section 6.03 Limitation on Liability of the Servicer and Others.

            Neither the Servicer nor any of the directors or officers or
employees or agents of the Servicer shall be under any liability to the Trust or
the Certificateholders for any action taken or for refraining from the taking of
any action by the Servicer in good faith pursuant to this Agreement, or for
errors in judgment; provided, however, that this provision shall not protect the
Servicer or any such Person against any liability which would otherwise be
imposed by reason of its willful misfeasance, bad faith or negligence in the
performance of duties of the Servicer or by reason of its reckless disregard of
its obligations and duties of the Servicer hereunder; provided, further, that
this provision shall not be construed to entitle the Servicer to indemnity in
the event that amounts advanced by the Servicer to retire any senior lien exceed
Liquidation Proceeds (in excess of related liquidation expenses) realized with
respect to the related Mortgage Loan. The Servicer and any director or officer
or employee or agent of the Servicer may rely in good faith on any document of
any kind prima facie properly executed and submitted by any Person respecting
any matters arising hereunder. The Servicer and any director or officer or
employee or agent of the Servicer shall be indemnified by the Trust and held
harmless against any loss, liability or expense incurred in connection with any
legal action relating to this Agreement or the Certificates, other than any
loss, liability or expense incurred by reason of its willful misfeasance, bad
faith or negligence in the performance of duties hereunder or by reason of its
reckless disregard of obligations and duties hereunder. The Servicer may
undertake any such action which it may deem necessary or desirable in respect of
this Agreement, and the rights and duties of the parties hereto and the
interests of the Certificateholders hereunder. In such event, the reasonable
legal expenses and costs of such action and any liability resulting therefrom
shall be expenses, costs and liabilities of the Trust and the Servicer shall be
entitled to pay such expenses from the proceeds of the Trust or to be reimbursed
therefor pursuant to Section 3.05 upon presentation to the Trustee of
documentation of such expenses, costs and liabilities. 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). This paragraph shall apply to the Servicer solely
in its capacity as Servicer hereunder and in no other capacities.

            Section 6.04 Servicer Not to Resign.

            Subject to the provisions of Section 7.01 and Section 6.02, the
Servicer shall not resign from the obligations and duties hereby imposed on it
except (i) upon determination that the performance of its obligations or duties
hereunder are no longer permissible under applicable law or are in material
conflict by reason of applicable law with any other activities carried on by it
or its subsidiaries or Affiliates, the other activities of the Servicer so
causing such a conflict being of a type and nature carried on by the Servicer or
its subsidiaries or Affiliates at the date of this Agreement or (ii) upon
satisfaction of the following conditions: (a) the Servicer has proposed a
successor servicer to the Trustee and the NIMS Insurer in writing and such
proposed successor servicer is reasonably acceptable to the Trustee and the NIMS
Insurer; and (b) each Rating Agency shall have delivered a letter to the Trustee
and the NIMS Insurer prior to the appointment of the successor servicer stating
that the proposed appointment of such successor servicer as Servicer hereunder
will not result in the reduction or withdrawal of the then current rating of the
Regular Certificates or the ratings that are in effect; provided, however, that
no such resignation by the Servicer shall become effective until such successor
servicer or, in the case of (i) above, the Trustee shall have assumed the
Servicer's responsibilities and obligations hereunder or the Trustee shall have
designated a successor servicer in accordance with Section 7.02. 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. Any such determination permitting
the resignation of the Servicer shall be evidenced by an Opinion of Counsel to
such effect delivered to the Trustee and the NIMS Insurer.

            Section 6.05 Delegation of Duties.

            (a) In the ordinary course of business, the Servicer at any time may
delegate any of its duties hereunder to any Person, including any of its
Affiliates, who agrees to conduct such duties in accordance with standards
comparable to those set forth in Section 3.01. Such delegation shall not relieve
the Servicer of its liabilities and responsibilities with respect to such duties
and shall not constitute a resignation within the meaning of Section 6.04. The
Servicer shall provide the Trustee, the NIMS Insurer and the Rating Agencies
with 60 days prior written notice prior to the delegation of any of its duties
to any Person other than any of the Servicer's Affiliates or their respective
successors and assigns.

            (b) The Servicer is hereby authorized, with the consent of the NIMS
Insurer, to enter into a financing or other facility (any such arrangement, an
"Advance Facility") under which (1) the Servicer 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 (2) an Advancing Person agrees to fund
some or all Advances and/or Servicing Advances required to be made by the
Servicer pursuant to this Agreement. The Servicer shall notify each other party
to this Agreement prior to or promptly after entering into or terminating any
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. If the Servicer enters into an Advance Facility, and for so long
as an Advancing Person remains entitled to receive reimbursement for any
Advances and/or Servicing Advances, as applicable, pursuant to this Agreement,
then the Servicer shall not be permitted to reimburse itself for Advances and/or
Servicing Advances, but instead the Servicer shall be required to remit amounts
collected that would otherwise be retained by the Servicer to reimburse it for
the amount of previously unreimbursed Advances ("Advance Reimbursements") and/or
previously unreimbursed Servicing Advances ("Servicing Advance Reimbursements"
and together with Advance Reimbursements, "Reimbursements") (in each case to the
extent such type of Reimbursements are included in the Advance Facility) 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 anything to the
contrary herein, in no event shall Advance Reimbursements or Servicing Advance
Reimbursements be included in the "Available Funds" or distributed to
Certificateholders. If the terms of a facility proposed to be entered into with
an Advancing Person by the Servicer would not materially and adversely affect
the interests of any Certificateholder, then the NIMS Insurer shall not withhold
its consent to the Servicer's entering such facility.

            Reimbursements 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). Notwithstanding the foregoing, no Person shall be entitled
to reimbursement from funds held in the Collection Account for future
distribution to Certificateholders pursuant to this Agreement. None of the
Depositor or the Trustee shall have any duty or liability with respect to the
calculation or payment of any Reimbursements, nor shall the Depositor or the
Trustee have any responsibility to track or monitor the administration of the
Advance Facility or the payment of Reimbursements to the related Advancing
Person or Advance Facility Trustee. The Servicer shall maintain and provide to
any successor servicer and (upon request) the Trustee 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.

            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 hereunder are limited to the funding of Advances and/or Servicing
Advances shall not be required to meet the criteria for qualification of a
subservicer set forth in this Agreement.

            The documentation establishing any Advance Facility shall require
that Reimbursements distributed with respect to each Mortgage Loan be allocated
to outstanding 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 documentation shall also require the Servicer to provide to the related
Advancing Person or Advance Facility Trustee loan by loan information with
respect to each Reimbursement distributed to such Advancing Person or Advance
Facility Trustee on each Distribution Date, to enable the Advancing Person or
Advance Facility Trustee to make the FIFO allocation of each Reimbursement with
respect to each Mortgage Loan. The Servicer shall remain entitled to be
reimbursed by the Advancing Person or Advance Facility Trustee for all Advances
and Servicing Advances funded by the Servicer to the extent the related rights
to be reimbursed therefor have not been assigned or pledged to an Advancing
Person.

            The Servicer shall indemnify the Depositor, the Trustee, the NIMS
Insurer, any successor servicer and the Trust Fund resulting from any claim by
the related Advancing Person, except to the extent that such claim, loss,
liability or damage resulted from or arose out of negligence, recklessness or
willful misconduct on the part of the Depositor, the Trustee or any successor
servicer.

            Any amendment to this Section 6.05(b) 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 6.05(b), including
amendments to add provisions relating to a successor servicer, may be entered
into by the Trustee, the Depositor and the Servicer without the consent of any
Certificateholder but with the consent of the NIMS Insurer, provided such
amendment complies with Section 11.01 hereof. All reasonable costs and expenses
(including attorneys' fees) of each party hereto of any such amendment shall be
borne solely by the Servicer. Prior to entering into an Advance Facility, the
Servicer shall notify the lender under such facility in writing that: (a) the
Advances and/or Servicing Advances financed by and/or pledged to the lender are
obligations owed to the Servicer on a non-recourse basis payable only from the
cash flows and proceeds received under this Agreement for reimbursement of
Advances and/or Servicing Advances only to the extent provided herein, and the
Trustee and the Trust are not otherwise obligated or liable to repay any
Advances and/or Servicing Advances financed by the lender; (b) the Servicer will
be responsible for remitting to the lender the applicable amounts collected by
it as reimbursement for Advances and/or Servicing Advances funded by the lender,
subject to the restrictions and priorities created in this Agreement; and (c)
the Trustee shall not have any responsibility to track or monitor the
administration of the financing arrangement between the Servicer and the lender.

                                  ARTICLE VII

                                     DEFAULT

            Section 7.01 Servicer Events of Termination.

            (a) If any one of the following events ("Servicer Events of
Termination") shall occur and be continuing:

            (i) (A) The failure by the Servicer to make any Advance or to pay
      Compensating Interest; or (B) any other failure by the Servicer to deposit
      in the Collection Account or remit to the Trustee for deposit in the
      Distribution Account any payment required to be made under the terms of
      this Agreement, which failure continues unremedied for a period of one
      Business Day after the first date on which (x) the Servicer has knowledge
      of such failure or (y) written notice of such failure is given to the
      Servicer; or

            (ii) The failure by the Servicer to make any required Servicing
      Advance which failure continues unremedied for a period of 30 days, or the
      failure by the Servicer duly to observe or perform, in any material
      respect, any other covenants, obligations or agreements of the Servicer as
      set forth in this Agreement, which failure continues unremedied for a
      period of 30 days (or five days in the case of the failure to observe or
      perform any of the obligations set forth in Section 3.16, 3.19, 3.20, 3.31
      or 6.02), after the date (A) on which written notice of such failure,
      requiring the same to be remedied, shall have been given to the Servicer
      by the Trustee or the NIMS Insurer or by any Holder of a Regular
      Certificate evidencing at least 25% of the Voting Rights or (B) actual
      knowledge of such failure by a Servicing Officer of the Servicer; or

            (iii) The entry against the Servicer of a decree or order by a court
      or agency or supervisory authority having jurisdiction in the premises for
      the appointment of a trustee, conservator, receiver or liquidator in any
      insolvency, conservatorship, receivership, readjustment of debt,
      marshalling of assets and liabilities or similar proceedings, or for the
      winding up or liquidation of its affairs, and the continuance of any such
      decree or order unstayed and in effect for a period of 60 days; or

            (iv) The Servicer shall voluntarily go into liquidation, consent to
      the appointment of a conservator or receiver or liquidator or similar
      person in any insolvency, readjustment of debt, marshalling of assets and
      liabilities or similar proceedings of or relating to the Servicer or of or
      relating to all or substantially all of its property; or a decree or order
      of a court or agency or supervisory authority having jurisdiction in the
      premises for the appointment of a conservator, receiver, liquidator or
      similar person in any insolvency, readjustment of debt, marshalling of
      assets and liabilities or similar proceedings, or for the winding-up or
      liquidation of its affairs, shall have been entered against the Servicer
      and such decree or order shall have remained in force undischarged,
      unbonded or unstayed for a period of 60 days; or the Servicer shall admit
      in writing its inability to pay its debts generally as they become due,
      file a petition to take advantage of any applicable insolvency or
      reorganization statute, make an assignment for the benefit of its
      creditors or voluntarily suspend payment of its obligations; or

            (v) As of any Distribution Date, if the average for the related
      Collection Period and the two preceding Collection Periods of the
      fraction, expressed as a percentage, the numerator of which is (a) the
      aggregate Principal Balance of 60+ Day Delinquent Loans and the
      denominator of which is (b) the aggregate Principal Balance of the
      Mortgage Loans, in the case of both (a) and (b), as of the last day of
      each such Collection Period, exceeds [__]%.

            (b) Then, and in each and every such case, so long as a Servicer
Event of Termination shall not have been remedied within the applicable grace
period, (x) with respect solely to clause (i)(A) above, if such Advance is not
made by 2:00 P.M., New York time, on the Business Day immediately following the
Servicer Remittance Date, the Trustee may terminate all of the rights and
obligations of the Servicer under this Agreement and the Trustee, or a successor
servicer appointed in accordance with Section 7.02, shall immediately make such
Advance and assume, pursuant to Section 7.02, the duties of a successor servicer
and (y) in the case of (i)(B), (ii), (iii), (iv) and (v) above, the Trustee
shall, at the direction of the NIMS Insurer or Holders of each Class of Regular
Certificates evidencing Percentage Interests aggregating not less than 51%, by
notice then given in writing to the Servicer (and to the Trustee if given by
Holders of Certificates), terminate all of the rights and obligations of the
Servicer as servicer under this Agreement. Any such notice to the Servicer shall
also be given to each Rating Agency, the NIMS Insurer and the Depositor. On or
after the receipt by the Servicer (and by the Trustee if such notice is given by
the Holders) of such written notice, all authority and power of the Servicer
under this Agreement, whether with respect to the Certificates or the Mortgage
Loans or otherwise, shall pass to and be vested in the Trustee pursuant to and
under this Section or successor servicer appointed in connection with Section
7.02; and, without limitation, the Trustee or successor servicer is hereby
authorized and empowered to execute and deliver, on behalf of the Servicer, as
attorney-in-fact or otherwise, any and all documents and other instruments, and
to do or accomplish all other acts or things necessary or appropriate to effect
the purposes of such notice of termination, whether to complete the transfer and
endorsement of each Mortgage Loan and Related Documents or otherwise. The
Servicer agrees to cooperate with the Trustee (or the applicable successor
servicer) in effecting the termination of the responsibilities and rights of the
Servicer hereunder, including, without limitation, the delivery to the Trustee
(or the applicable successor servicer) of all documents and records requested by
it to enable it to assume the Servicer's functions under this Agreement within
ten Business Days subsequent to such notice, the transfer within one Business
Day subsequent to such notice to the Trustee (or the applicable successor
servicer) for the administration by it of all cash amounts that shall at the
time be held by the Servicer and to be deposited by it in the Collection
Account, the Distribution Account or any Escrow Account or that have been
deposited by the Servicer in such accounts or thereafter received by the
Servicer with respect to the Mortgage Loans or any REO Property received by the
Servicer. All reasonable out-of-pocket costs and expenses (including attorneys'
fees) incurred in connection with transferring the servicing to the successor
servicer and amending this Agreement to reflect such succession as Servicer
pursuant to this Section shall be paid by the predecessor servicer (or if the
predecessor servicer is the Trustee, the initial servicer) upon presentation of
reasonable documentation of such costs and expenses, 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 shall be entitled to reimbursement therefor from the assets of
the Trust).

            Notwithstanding any termination of the activities of a Servicer
hereunder, the Servicer shall be entitled to receive payment of all accrued and
unpaid Servicing Fees and reimbursement for all outstanding Advances and
Servicing Advances properly made prior to the date of termination.

            Section 7.02 Trustee to Act; Appointment of Successor.

            (a) Within 90 days of the time the Servicer (and the Trustee, if
notice is sent by the Holders) receives a notice of termination pursuant to
Section 7.01 or 6.04, the Trustee (or such other successor servicer as is
approved in accordance with this Agreement) 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 shall be subject to all
the responsibilities, duties and liabilities relating thereto placed on the
Servicer by the terms and provisions hereof arising on and after its succession.
As compensation therefor, the Trustee (or such other successor servicer) shall
be entitled to such compensation as the Servicer would have been entitled to
hereunder if no such notice of termination had been given. Notwithstanding the
above, (i) if the Trustee is unwilling to act as successor servicer or (ii) if
the Trustee is legally unable so to act, the Trustee shall appoint or petition a
court of competent jurisdiction to appoint, any established housing and home
finance institution, bank or other mortgage loan or home equity loan servicer
having a net worth of not less than $50,000,000 as the successor to the Servicer
hereunder in the assumption of all or any part of the responsibilities, duties
or liabilities of the Servicer hereunder; provided, that the appointment of any
such successor servicer will not result in the qualification, reduction or
withdrawal of the ratings assigned to the Certificates or the ratings that are
in effect by the Rating Agencies as evidenced by a letter to such effect from
the Rating Agencies and that, in the case of a successor servicer appointed by
the Trustee, such successor servicer is reasonably acceptable to the NIMS
Insurer. 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 successor servicer shall be entitled to withdraw from the
Collection Account all costs and expenses associated with the transfer of the
servicing to the successor servicer, including costs and expenses of the
Trustee. 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 3.11 or to indemnify the parties indicated in Section 3.26
pursuant to the terms thereof, 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.

            (b) Any successor, including the Trustee, to the Servicer as
servicer 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 3.12.

            Section 7.03 Waiver of Defaults.

            The Holders of Certificates entitled to at least 66 2/3% of the
Voting Rights allocated to the Classes of Certificates affected by a Servicer
Event of Termination may, on behalf of all Certificateholders, and with the
consent of the NIMS Insurer, waive any events permitting removal of the Servicer
as servicer pursuant to this Article VII, provided, however, that such Holders
may not waive a default in making a required distribution on a Certificate
without the consent of the Holder of such Certificate and the NIMS Insurer. Upon
any waiver of a past default, such default shall cease to exist and any Servicer
Event of Termination arising therefrom shall be deemed to have been remedied for
every purpose of this Agreement. No such waiver shall extend to any subsequent
or other default or impair any right consequent thereto except to the extent
expressly so waived. Notice of any such waiver shall be given by the Trustee to
the Rating Agencies.

            Section 7.04 Notification to Certificateholders.

            (a) On any termination or appointment of a successor to the Servicer
pursuant to this Article VII or Section 6.04, the Trustee shall give prompt
written notice thereof to the Certificateholders at their respective addresses
appearing in the Certificate Register, the NIMS Insurer and each Rating Agency.

            (b) No later than 60 days after the occurrence of any event which
constitutes or which, with notice or a lapse of time or both, would constitute a
Servicer Event of Termination for five Business 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 NIMS Insurer and all Certificateholders notice of
such occurrence unless such default or Servicer Event of Termination shall have
been waived or cured. Such notice shall be given to the Rating Agencies promptly
after any such occurrence.

            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

                                   THE TRUSTEE

            Section 8.01 Duties of Trustee.

            The Trustee, prior to the occurrence of a Servicer Event of
Termination of which a Responsible Officer of the Trustee shall have actual
knowledge and after the curing of all Servicer Events of Termination which may
have occurred, undertakes to perform such duties and only such duties as are
specifically set forth in this Agreement. If a Servicer Event of Termination has
occurred (which has not been cured) of which a Responsible Officer has actual
knowledge, 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.

            The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they
conform to the requirements of this Agreement; provided, however, that that the
Trustee shall not be responsible for the accuracy or content of any resolution,
certificate, statement, opinion, report, document, order or other instrument
furnished by the Servicer, the Seller, the NIMS Insurer or the Depositor
hereunder. If any such instrument is found not to conform in any material
respect to the requirements of this Agreement, the Trustee shall notify the
Certificateholders of such instrument in the event that the Trustee, after so
requesting, does not receive a satisfactorily corrected instrument.

            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 Termination of
      which a Responsible Officer of the Trustee shall have actual knowledge,
      and after the curing of all such Servicer Events of Termination 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 not be liable except for the performance of such duties and
      obligations as are specifically set forth in this Agreement, no implied
      covenants or obligations shall be read into this Agreement against the
      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 and conforming 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 of the Trustee,
      unless it shall be proved that the Trustee was negligent in ascertaining
      or investigating the facts related thereto;

            (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 Majority
      Certificateholders relating to the time, method and place of conducting
      any proceeding for any remedy available to the Trustee or exercising or
      omitting to exercise any trust or power conferred upon the Trustee under
      this Agreement; and

            (iv) the Trustee shall not be charged with knowledge of any failure
      by the Servicer to comply with the obligations of the Servicer referred to
      in clauses (i) and (ii) of Section 7.01(a) or any 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 Servicer, the NIMS
      Insurer or the Majority Certificateholders. In the absence of such receipt
      of such notice, the Trustee may conclusively assume that there is no
      Servicer Event of Termination.

            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 Servicer in accordance with the
terms of this Agreement.

            The Trustee shall not have any duty (A) to see to any recording,
filing, or depositing of this Agreement or any agreement referred to herein or
any financing statement or continuation statement evidencing a security
interest, or to see to the maintenance of any such recording or filing or
depositing or to any rerecording, refiling or redepositing of any thereof, (B)
to see to any insurance or (C) to see to the payment or discharge of any tax,
assessment, or other governmental charge or any lien or encumbrance of any kind
owing with respect to, assessed or levied against, any part of the Trust Fund
other than from funds available in the Distribution Account.

            Upon its receipt from the Sponsor of each "significance estimate" of
each Yield Maintenance Agreement pursuant to the Mortgage Loan Purchase
Agreement, the Trustee shall, on the basis of each such "significance estimate,"
calculate each Yield Maintenance Agreement's "significance percentage" of the
aggregate Certificate Principal Balance of the Certificates to which such Yield
Maintenance Agreement relates as of the date of such "significance estimate."
For the avoidance of doubt, such "significance percentage" shall be a fraction,
expressed as a percentage, the numerator of which is such "significance
estimate" and the denominator of which is the related aggregate Certificate
Principal Balance. Further, the Trustee shall determine as of such date whether
such "significance percentage" would require disclosure of financial information
with respect to the Yield Maintenance Agreement Provider in any report required
to be filed with the Commission pursuant to Section 3.31, and if it does, the
Trustee shall make a written request of the Yield Maintenance Agreement Provider
for such information in accordance with the applicable Yield Maintenance
Agreement not later than the third Business Day after it receives the related
"significance estimate." Upon its receipt of such information, the Trustee shall
include such information in the related report as provided in Section 3.31.

            To the extent the Trustee engages any Subcontractor in connection
with the performance of any of its duties under this Agreement, the Trustee
shall immediately notify the Depositor in writing of such engagement and shall
provide a written description (in form and substance satisfactory to the
Depositor) of the role and function of such Subcontractor. To the extent the
Depositor notifies the Trustee that it has determined that any such
Subcontractor is a Servicing Function Participant, the Trustee shall cause such
Servicing Function Participant to prepare a separate assessment and attestation
report, as contemplated by Section 3.20 of this Agreement and deliver such
report to the Trustee as set forth in Section 3.31 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, Officer's
      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 advice or Opinion
      of Counsel shall be full and complete authorization and protection in
      respect of any action taken or suffered or omitted by it hereunder in good
      faith and in accordance with such advice or Opinion of Counsel;

            (iii) the Trustee shall not be under any obligation to exercise any
      of the rights 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 the Certificateholders or the NIMS Insurer
      pursuant to the provisions of this Agreement, unless such
      Certificateholders or the NIMS Insurer shall have offered to the Trustee
      reasonable security or indemnity against the costs, expenses and
      liabilities which may be incurred therein or thereby; the right of the
      Trustee to perform any discretionary act enumerated in this Agreement
      shall not be construed as a duty, and the Trustee shall not be answerable
      for other than its negligence or willful misconduct in the performance of
      any such act;

            (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 Termination and
      after the curing of all Servicer Events of Termination 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 documents, unless requested in writing to do so by
      the Majority Certificateholders or the NIMS Insurer; provided, however,
      that if the payment within a reasonable time to the Trustee of the costs,
      expenses or liabilities likely to be incurred by it in the making of such
      investigation is, in the opinion of the Trustee, not reasonably assured to
      the Trustee by the security afforded to it by the terms of this Agreement,
      the Trustee may require reasonable indemnity against such cost, expense or
      liability as a condition to such proceeding. The reasonable expense of
      every such examination shall be paid by the Servicer or, if paid by the
      Trustee, shall be reimbursed by the Servicer upon demand. Nothing in this
      clause (v) shall derogate from the obligation of the Servicer to observe
      any applicable law prohibiting disclosure of information regarding the
      Mortgagors;

            (vi) the Trustee shall not be accountable, have any liability or
      make any representation as to any acts or omissions hereunder of the
      Servicer until such time as the Trustee may be required to act as Servicer
      pursuant to Section 7.02;

            (vii) 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 or a custodian and the Trustee shall not be responsible for any
      misconduct or negligence on the part of any such agent, attorney or
      custodian appointed by it with due care; and

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

            Section 8.03 Trustee Not Liable for Certificates or Mortgage Loans.

            The recitals contained herein and in the Certificates (other than
the authentication of the Trustee on the Certificates) shall be taken as the
statements of the Depositor, and the Trustee assumes no responsibility for the
correctness of the same. The Trustee makes no representations as to the validity
or sufficiency of this Agreement or of the Certificates (other than the
signature and authentication of the Trustee on the Certificates) or of any
Mortgage Loan or Related Document. The Trustee shall not be accountable for the
use or application by the Servicer, or for the use or application of any funds
paid to the Servicer in respect of the Mortgage Loans or deposited in or
withdrawn from the Collection Account by the Servicer. The Trustee shall not at
any time have any responsibility or liability for or with respect to the
legality, validity and enforceability of any Mortgage or any Mortgage Loan, or
the perfection and priority of any Mortgage or the maintenance of any such
perfection and priority, or for or with respect to the sufficiency of the Trust
or its ability to generate the payments to be distributed to Certificateholders
under this Agreement, including, without limitation: the existence, condition
and ownership of any Mortgaged Property; the existence and enforceability of any
hazard insurance thereon (other than if the Trustee shall assume the duties of
the Servicer pursuant to Section 7.02); the validity of the assignment of any
Mortgage Loan to the Trustee or of any intervening assignment; the completeness
of any Mortgage Loan; the performance or enforcement of any Mortgage Loan (other
than if the Trustee shall assume the duties of the Servicer pursuant to Section
7.02); the compliance by the Depositor or the Servicer with any warranty or
representation made under this Agreement or in any related document or the
accuracy of any such warranty or representation prior to the Trustee's receipt
of notice or other discovery of any non-compliance therewith or any breach
thereof; any investment of monies by or at the direction of the Servicer or any
loss resulting therefrom, it being understood that the Trustee shall remain
responsible for any Trust property that it may hold in its individual capacity;
the acts or omissions of any of the Servicer (other than if the Trustee shall
assume the duties of the Servicer pursuant to Section 7.02), or any Mortgagor;
any action of the Servicer (other than if the Trustee shall assume the duties of
the Servicer pursuant to Section 7.02), taken in the name of the Trustee; the
failure of the Servicer to act or perform any duties required of it as agent of
the Trustee hereunder; or any action by the Trustee taken at the instruction of
the Servicer (other than if the Trustee shall assume the duties of the Servicer
pursuant to Section 7.02); provided, however, that the foregoing shall not
relieve the Trustee of its obligation to perform its duties under this
Agreement. The Trustee shall not have any responsibility for filing any
financing or continuation statement in any public office at any time or to
otherwise perfect or maintain the perfection of any security interest or lien
granted to it hereunder.

            Section 8.04 Trustee May Own Certificates.

            The Trustee in its individual or any other capacity may become the
owner or pledgee of Certificates with the same rights as it would have if it
were not Trustee and may transact any banking and trust business with the
Servicer, the Depositor or their Affiliates.

            Section 8.05 Trustee Fees and Expenses.

            The Trustee shall be entitled to the Trustee Fee (which shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust) for all services rendered by the Trustee in the exercise and
performance of any of the powers and duties hereunder. The Trustee shall
withdraw from the Distribution Account on each Distribution Date and pay to
itself the Trustee Fee. The Trust shall reimburse the Trustee for all reasonable
expenses, disbursements and advances incurred or made by the Trustee in
accordance with any of the provisions of this Agreement (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all persons not regularly in its employ) except any such expense, disbursement
or advance as may arise from its negligence or bad faith or which is the
responsibility of Certificateholders or the Trustee hereunder. In addition, the
Trustee and its officers, directors, employees and agents shall be indemnified
by the Trust from, and held harmless against, any and all losses, liabilities,
damages, claims or expenses incurred in connection with any legal action
relating to this Agreement or the Certificates, other than any loss, liability
or expense incurred by reason of willful misfeasance, bad faith or negligence of
the Trustee in the performance of its duties hereunder or by reason of the
Trustee's reckless disregard of obligations and duties hereunder. This Section
shall survive termination of this Agreement or the resignation or removal of any
Trustee hereunder.

            Section 8.06 Eligibility Requirements for Trustee.

            The Trustee hereunder shall at all times be an entity duly organized
and validly existing under the laws of the United States of America or any state
thereof, authorized under such laws to exercise corporate trust powers, having a
combined capital and surplus of at least $50,000,000 and a minimum long-term
debt rating of BBB by [___] and [___] and subject to supervision or examination
by federal or state authority. If such entity publishes reports of condition at
least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section 8.06,
the combined capital and surplus of such entity shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. The principal office of the Trustee (other than the initial
Trustee) shall be in a state with respect to which an Opinion of Counsel has
been delivered to such Trustee at the time such Trustee is appointed Trustee to
the effect that the Trust will not be a taxable entity under the laws of such
state. In case at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 8.06, the Trustee shall resign immediately
in the manner and with the effect specified in Section 8.07.

            Section 8.07 Resignation or Removal of Trustee.

            The Trustee may at any time resign and be discharged from the trusts
hereby created by giving written notice thereof to the Depositor, the Servicer,
the NIMS Insurer and each Rating Agency. Upon receiving such notice of
resignation, the Depositor shall promptly appoint a successor Trustee reasonably
acceptable to the NIMS Insurer by written instrument, in duplicate, one copy of
which instrument shall be delivered to the resigning Trustee and one copy to the
successor Trustee. If no successor Trustee shall have been so appointed and
having 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 be legally unable to act, or shall be adjudged a bankrupt or
insolvent, or a receiver of the Trustee or of their property shall be appointed,
or any public officer shall take charge or control of the Trustee or of their
property or affairs for the purpose of rehabilitation, conservation or
liquidation, then the Depositor or the NIMS Insurer may remove the Trustee. If
the Depositor or the NIMS Insurer removes the Trustee under the authority of the
immediately preceding sentence, the Depositor or the NIMS Insurer, as the case
may be, shall promptly appoint a successor Trustee (reasonably acceptable to the
NIMS Insurer if appointed by the Depositor) by written instrument, in duplicate,
one copy of which instrument shall be delivered to the Trustee so removed and
one copy to the successor Trustee.

            The Majority Certificateholders or the NIMS Insurer may at any time
remove the Trustee by written instrument or instruments delivered to the
Servicer, the Depositor, the NIMS Insurer and the Trustee; the Depositor shall
thereupon use its best efforts to appoint a successor Trustee reasonably
acceptable to the NIMS Insurer in accordance with this Section.

            Any resignation or removal of the Trustee and appointment of a
successor Trustee pursuant to any of the provisions of this Section 8.07 shall
not become effective until acceptance of appointment by the successor Trustee as
provided in Section 8.08.

            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, the Rating
Agencies, the Servicer and to its predecessor Trustee an instrument accepting
such appointment hereunder, and thereupon the resignation or removal of the
predecessor Trustee shall become effective, and such successor Trustee, without
any further act, deed or conveyance, shall become fully vested with all the
rights, powers, duties and obligations of its predecessor hereunder, with like
effect as if originally named as Trustee. The Depositor, the Servicer and the
predecessor Trustee shall execute and deliver such instruments and do such other
things as may reasonably be required for 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 8.08 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 the Regular Certificates
by either Rating Agency, as evidenced by a letter from each Rating Agency.

            Upon acceptance of appointment by a successor Trustee as provided in
this Section 8.08, the successor Trustee shall mail notice of the appointment of
a successor Trustee hereunder to all Holders of Certificates at their addresses
as shown in the Certificate Register and to each Rating Agency.

            The predecessor Trustee and successor Trustee shall notify the
Depositor of any such appointment and shall furnish to the Depositor in writing
and in form and substance reasonably satisfactory to the Depositor, all
information reasonably necessary for the Trustee to accurately and timely
report, pursuant to Section 3.31(d), the event under Item 6.02 of Form 8-K
pursuant to the Exchange Act (if such reports are required to be filed under the
Exchange Act).

            Section 8.09 Merger or Consolidation of Trustee.

            Any entity into which the Trustee may be merged or converted or with
which it may be consolidated, or any entity resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any entity
succeeding to the business of the Trustee, shall be the successor of the
hereunder, provided such entity shall be eligible under the provisions of
Section 8.06 and 8.08, 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. In connection with the succession to the Trustee under
this Agreement by any Person (i) into which the Trustee may be merged or
consolidated, or (ii) which may be appointed as a successor to the Trustee, the
Trustee shall notify the Depositor of such succession or appointment and shall
furnish to the Depositor in writing and in form and substance reasonably
satisfactory to the Depositor, all information reasonably necessary for the
Trustee to accurately and timely report, pursuant to Section 3.31(d), the event
under Item 6.02 of Form 8-K pursuant to the Exchange Act (if such reports are
required to be filed under the Exchange Act).

            Section 8.10 Appointment of Co-Trustee or Separate Trustee.

            Notwithstanding any other provisions of this Agreement, at any time,
for the purpose of meeting any legal requirements of any jurisdiction in which
any part of the Trust or any Mortgaged Property may at the time be located, the
Depositor and the Trustee acting jointly 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 the
Trust, and to vest in such Person or Persons, in such capacity and for the
benefit of the Certificateholders, such title to the Trust, or any part thereof,
and, subject to the other provisions of this Section 8.10, such powers, duties,
obligations, rights and trusts as the Servicer and the Trustee may consider
necessary or desirable. Any such co-trustee or separate trustee shall be subject
to the written approval of the Servicer and the NIMS Insurer. If the Servicer
and the NIMS Insurer shall not have joined in such appointment within 15 days
after the receipt by it of a request so to do, or in the case a Servicer Event
of Termination shall have occurred and be continuing, 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, and no notice to Certificateholders of the
appointment of any co-trustee or separate trustee shall be required under
Section 8.08.

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

            (i) 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
      (it being understood that such separate trustee or co-trustee is not
      authorized to act separately without the Trustee joining in such act),
      except to the extent that under any law of any jurisdiction in which any
      particular act or acts are to be performed (whether as Trustee hereunder
      or as successor to the 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 the Trust or any portion thereof in any such jurisdiction) shall
      be exercised and performed singly by such separate trustee or co-trustee,
      but solely at the direction of the Trustee;

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

            (iii) the Servicer and the Trustee, acting jointly may at any time
      accept the resignation of or remove any separate trustee or co-trustee
      except that following the occurrence of a Servicer Event of Termination,
      the Trustee acting alone may accept the resignation or remove any separate
      trustee or co-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 trusts conferred, shall be vested with the estates or property specified
in its instrument of appointment, either jointly with the Trustee or separately,
as may be provided therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee and a copy thereof given to the
Depositor, the NIMS Insurer, the Rating Agencies and the Servicer.

            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.

            Section 8.11 Limitation of Liability.

            The Certificates are executed by the Trustee, not in its individual
capacity but solely as Trustee of the Trust, in the exercise of the powers and
authority conferred and vested in it by this Agreement. Each of the undertakings
and agreements made on the part of the Trustee in the Certificates is made and
intended not as a personal undertaking or agreement by the Trustee but is made
and intended for the purpose of binding only the Trust.

            Section 8.12 Trustee May Enforce Claims Without Possession of
Certificates.

            (a) All rights of action and claims under this Agreement or the
Certificates may be prosecuted and enforced by the Trustee without the
possession of any of the Certificates or the production thereof in any
proceeding relating thereto, and such proceeding instituted by the Trustee shall
be brought in its own name or in its capacity as Trustee for the benefit of all
Holders of such Certificates, subject to the provisions of this Agreement. Any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursement and advances of the Trustee, its agents and
counsel, be for the ratable benefit of the Certificateholders in respect of
which such judgment has been recovered.

            (b) The Trustee shall afford the Depositor, the Servicer, the NIMS
Insurer and each Certificateholder upon reasonable notice during normal business
hours, access to all records maintained by the Trustee in respect of its duties
hereunder and access to officers of the Trustee responsible for performing such
duties. The Trustee shall cooperate fully with the Servicer, the NIMS Insurer,
the Depositor and such Certificateholder and shall make available to the
Servicer, the NIMS Insurer, the Depositor and such Certificateholder for review
and copying at the expense of the party requesting such copies, such books,
documents or records as may be requested with respect to the Trustee's duties
hereunder. The Depositor, the Servicer, the NIMS Insurer and the
Certificateholders shall not have any responsibility or liability for any action
or failure to act by the Trustee and are not obligated to supervise the
performance of the Trustee under this Agreement or otherwise.

            Section 8.13 Suits for Enforcement.

            In case a Servicer Event of Termination or other default by the
Servicer hereunder shall occur and be continuing, the Trustee may proceed to
protect and enforce its rights and the rights of the Certificateholders under
this Agreement by a suit, action or proceeding in equity or at law or otherwise,
whether for the specific performance of any covenant or agreement contained in
this Agreement or in aid of the execution of any power granted in this Agreement
or for the enforcement of any other legal, equitable or other remedy, as the
Trustee, being advised by counsel, and subject to the foregoing, shall deem most
effectual to protect and enforce any of the rights of the Trustee and the
Certificateholders.

            Section 8.14 Waiver of Bond Requirement.

            The Trustee shall be relieved of, and each Certificateholder hereby
waives, any requirement of any jurisdiction in which the Trust, or any part
thereof, may be located that the Trustee post a bond or other surety with any
court, agency or body whatsoever.

            Section 8.15 Waiver of Inventory, Accounting and Appraisal
Requirement.

            The Trustee shall be relieved of, and each Certificateholder hereby
waives, any requirement of any jurisdiction in which the Trust, or any part
thereof, may be located that the Trustee file any inventory, accounting or
appraisal of the Trust with any court, agency or body at any time or in any
manner whatsoever.

                                   ARTICLE IX

                     REMIC AND GRANTOR TRUST ADMINISTRATION

            Section 9.01 REMIC Administration.

            (a) The Trustee shall (i) make or cause to be made REMIC elections
for each of REMIC 1 and REMIC 2 as set forth in the Preliminary Statement on
Forms 1066 or other appropriate federal tax or information return for the
taxable year ending on the last day of the calendar year in which the
Certificates are issued, and (ii) file Form 8811, or other applicable form,
within 30 days of the Closing Date (or such other period as may be allowed by
applicable law), indicating the name, title, address and telephone number of the
Person who will serve as the representative of REMIC 2. The regular interests
and residual interest in each REMIC shall be as designated in the Preliminary
Statement.

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

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

            (d) The Trustee shall prepare or cause to be prepared, sign and file
or cause to be filed, each REMIC's federal and state tax and information returns
as such REMIC's direct representative. The expenses of preparing and filing such
returns shall be borne by the Trustee.

            (e) The Holder of the Class R Certificate shall be the "tax matters
person" as defined in the REMIC Provisions (the "Tax Matters Person") with
respect to each REMIC, and the Trustee is irrevocably designated as and shall
act as attorney-in-fact and agent for such Tax Matters Person for each REMIC.
The Trustee, as agent for the Tax Matters Person, shall perform, on behalf of
each REMIC, all reporting and other tax compliance duties that are the
responsibility of such REMIC under the Code, the REMIC Provisions, or other
compliance guidance issued by the Internal Revenue Service or any state or local
taxing authority. Among its other duties, if required by the Code, the REMIC
Provisions, or other such guidance, the Trustee, as agent for the Tax Matters
Person, shall provide (i) to the Treasury or other governmental authority such
information as is necessary for the application of any tax relating to the
transfer of the Class R or Class R-X Certificate to any disqualified person or
organization and (ii) to the Certificateholders such information or reports as
are required by the Code or REMIC Provisions.

            (f) The Trustee, the Servicer, and the Holders of Certificates shall
take any action or cause any REMIC formed under this Agreement to take any
action necessary to create or maintain the status of such REMIC as a REMIC under
the REMIC Provisions and shall assist each other as necessary to create or
maintain such status. None of the Trustee, the Servicer or the Holder of the
Class R or Class R-X Certificate shall take any action or cause any REMIC formed
under this Agreement to take any action or fail to take (or fail to cause to be
taken) any action that, under the REMIC Provisions, if taken or not taken, as
the case may be, could (i) endanger the status of such REMIC as a REMIC or (ii)
result in the imposition of a tax upon such REMIC (including but not limited to
the tax on prohibited transactions as defined in Code Section 860F(a)(2) and the
tax on prohibited contributions set forth on Section 860G(d) of the Code)
(either such event, an "Adverse REMIC Event") unless the Trustee, the NIMS
Insurer and the Servicer have received an Opinion of Counsel (at the expense of
the party seeking to take such action) to the effect that the contemplated
action will not endanger such status or result in the imposition of such a tax.
In addition, prior to taking any action with respect to any REMIC formed under
this Agreement or the assets therein, or causing such REMIC to take any action,
which is not expressly permitted under the terms of this Agreement, any Holder
of the Class R or Class R-X Certificate will consult with the Trustee, the NIMS
Insurer and the Servicer, or their respective designees, in writing, with
respect to whether such action could cause an Adverse REMIC Event to occur with
respect to such REMIC, and no such Person shall take any such action or cause
such REMIC to take any such action as to which the Trustee, the NIMS Insurer or
the Servicer has advised it in writing that an Adverse REMIC Event could occur.

            (g) The Holder of the Class R Certificate shall pay when due any and
all taxes imposed on any REMIC formed under this Agreement by federal or state
governmental authorities, but only from amounts, if any, distributable thereon.
To the extent that such REMIC taxes are not paid by the Class R
Certificateholder, the Trustee shall pay any remaining REMIC taxes out of future
amounts otherwise distributable to the Holder of the Class R Certificate or, if
no such amounts are available, out of other amounts held in the Distribution
Account, and shall reduce amounts otherwise payable to Holders of the REMIC
Regular Interests or the Certificates, as the case may be.

            (h) The Trustee, shall, for federal income tax purposes, maintain or
cause to be maintained books and records with respect to each REMIC formed under
this Agreement on a calendar year and on an accrual basis.

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

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

            (k) On or before April 15 of each calendar year, beginning in 20 ,
the Trustee shall deliver to each Rating Agency and the NIMS Insurer an
Officer's Certificate stating the Trustee's compliance with the provisions of
this Section 9.01.

            (l) The Trustee shall treat (i) the rights of the Offered
Certificates and the Class M-7 Certificates to receive Cap Carryover Amounts as
a right in interest rate cap contracts written by the Class CE
Certificateholders in favor of the Holders of the Offered Certificates and the
Class M-7 Certificates and (ii) the rights of the Class CE Certificates under
the Class A-1 Yield Maintenance Agreement, Group 2-A Yield Maintenance Agreement
and Class M Yield Maintenance Agreement in accordance with the terms thereof and
shall assign such rights for federal tax return and information reporting a
value of zero. The Trustee shall account for such as property held separate and
apart from the regular interests it holds in each of the REMICs created
hereunder. The provisions of this paragraph are intended to satisfy the
requirements of Treasury Regulations Section 1.860G-2(i) for the treatment of
property rights coupled with regular interests to be separately respected and
shall be interpreted consistent with such regulation. On each Distribution Date,
to the extent the Offered Certificates and the Class M-7 Certificates receive
interest in excess of their Certificate Interest Rate, such interest will be
treated as distributed to the Class CE Certificates, together with any amounts
deposited in the Class A-1 Reserve Account in respect of the Class A-1 Yield
Maintenance Agreement, the Group 2-A Reserve Account in respect of the Group 2-A
Yield Maintenance Agreement and the Class M Reserve Account in respect of the
Class M Yield Maintenance Agreement, and then paid to the respective Classes of
Offered Certificates and the Class M-7 Certificates pursuant to the related
interest rate cap agreement.

            Section 9.02 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 a disposition
pursuant to (i) the foreclosure of a Mortgage Loan, (ii) the bankruptcy of the
Trust Fund, (iii) the termination of any REMIC pursuant to Article X of this
Agreement, (iv) a substitution pursuant to Article II of this Agreement, (v) a
repurchase of Mortgage Loans pursuant to Article II of this Agreement or (vi) an
optional purchase by the Servicer pursuant to Section 3.16 of this Agreement,
nor acquire any assets for any REMIC constituting part of the Trust Fund, nor
sell or dispose of any investments in the Distribution Account for gain, nor
accept any contributions to any REMIC constituting part of the Trust Fund after
the Closing Date, unless such party and the NIMS Insurer has received an Opinion
of Counsel (at the expense of the party causing such sale, disposition, or
substitution) that such disposition, acquisition, substitution, or acceptance
will not (a) affect adversely the status of such REMIC as a REMIC or of the
interests therein other than the Class R or Class R-X Certificate as the regular
interests therein, (b) affect the distribution of interest or principal on the
Certificates, (c) result in the encumbrance of the assets transferred or
assigned to the Trust Fund (except pursuant to the provisions of this Agreement)
or (d) cause such REMIC to be subject to a tax on prohibited transactions or
prohibited contributions pursuant to the REMIC Provisions.

            Section 9.03 Indemnification with Respect to Certain Taxes and Loss
of REMIC Status.

            In the event that any REMIC formed hereunder fails to qualify as a
REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as a
result of a prohibited transaction or prohibited contribution under the REMIC
Provisions due to the negligent performance by the Servicer of its duties and
obligations set forth herein, the Servicer shall indemnify the Holder of the
Class R or Class R-X Certificate against any and all losses, claims, damages,
liabilities or expenses ("Losses") resulting from such negligence; 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 the
Class R or Class R-X Certificate, as applicable, nor for any such Losses
resulting from misinformation provided by the Holder of the Class R or Class R-X
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 the Class R or
Class R-X 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 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).

            Section 9.04 REO Property.

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

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

            Section 9.05 Grantor Trust Administration.

            The parties intend that the portions of the Trust Fund consisting of
the right of the Class P Certificates to receive Prepayment Charges, Originator
Prepayment Charge Payment Amounts and Servicer Prepayment Charge Payment
Amounts, the right of the Offered Certificates and the Class M-7 Certificates to
receive Cap Carryover Amounts, the Reserve Accounts and the right of the Class
CE Certificates to receive Yield Maintenance Agreement Payments subject to the
obligation of the Class CE Certificates to pay Cap Carryover Amounts, shall be
treated as a "grantor trust" under the Code, and the provisions hereof shall be
interpreted consistently with this intention. In furtherance of such intention,
the Trustee shall furnish or cause to be furnished (i) to the Holders of the
Offered Certificates and the Class M-7 Certificates, (ii) to the Holders of the
Class P Certificates and (iii) to the Holder of the Class CE Certificates and
shall file or cause to be filed with the Internal Revenue Service together with
Form 1041 or such other form as may be applicable, their allocable shares of
income and expenses with respect to the property held by the Grantor Trust, at
the time or times and in the manner required by the Code.

                                    ARTICLE X

                                   TERMINATION

            Section 10.01 Termination.

            (a) The respective obligations and responsibilities of the Servicer,
the Depositor, the Trustee and the Certificate Registrar created hereby (other
than the obligation of the Trustee to make certain payments to
Certificateholders after the final Distribution Date and the obligation of the
Servicer to send certain notices as hereinafter set forth) shall terminate upon
notice to the Trustee upon the earliest of (i) the Distribution Date on which
the Certificate Principal Balance of each Class of Certificates has been reduced
to zero, (ii) the final payment or other liquidation of the last Mortgage Loan
in the Trust, and (iii) the optional purchase by the NIMS Insurer, if there is a
NIMS Insurer, or if there is no NIMS Insurer, the Majority Class CE
Certificateholders (or if such holder is the Seller, or an affiliate of the
Seller, the Servicer of the Mortgage Loans) as described below. Notwithstanding
the foregoing, in no event shall the trust created hereby continue beyond the
expiration of 21 years from the death of the last survivor of the descendants of
Joseph P. Kennedy, the late ambassador of the United States to the Court of St.
James, living on the date hereof.

            The NIMS Insurer, if there is a NIMS Insurer, or if there is no NIMS
Insurer, the Majority Class CE Certificateholders (and, if such holder is the
Seller or an affiliate of the Seller, the Servicer of the Mortgage Loans) may,
at its option, terminate the Trust Fund and retire the Certificates on the next
succeeding Distribution Date upon which the aggregate current Pool Balance is
less than 10% of the aggregate Pool Balance of the Mortgage Loans as of the
Cut-off Date by purchasing all of the outstanding (i) Mortgage Loans in the
Trust Fund at a price equal to the sum of the outstanding Principal Balance of
the Mortgage Loans and except to the extent previously advanced by the Servicer,
accrued and unpaid interest thereon at the weighted average of the Mortgage
Interest Rates through the end of the Collection Period preceding the final
Distribution Date plus unreimbursed Servicing Advances, Advances and any unpaid
Servicing Fees allocable to such Mortgage Loans and (ii) REO Properties in the
Trust Fund at a price equal to their fair market value as determined in good
faith by the Servicer (the "Termination Price"). If the NIMS Insurer or the
Majority Class CE Certificateholders (or, if the Majority Class CE
Certificateholder is the Seller or an affiliate of the Seller, the Servicer) is
subject to regulation by the OCC, the FDIC, the Federal Reserve or the Office of
Thrift Supervision, however, the option may not be exercised unless the
aggregate fair market value of the Mortgage Loans and REO Properties is greater
than or equal to the Termination Price. Notwithstanding the foregoing, no party
may exercise this optional purchase right unless any Reimbursement Amount owed
to the Trust pursuant to Section 2.03 hereof has been paid.

            In connection with any such purchase pursuant to the preceding
paragraph, the Servicer shall deliver to the Trustee for deposit in the
Distribution Account all amounts then on deposit in the Collection Account (less
amounts permitted to be withdrawn by the Servicer pursuant to Section 3.07),
which deposit shall be deemed to have occurred immediately following such
purchase.

            Any such purchase shall be accomplished by delivery on the
Determination Date before such Distribution Date of the Termination Price to the
Trustee for deposit into the Distribution Account as part of Available Funds.

            (b) Notice of any termination, specifying the Distribution Date
(which shall be a date that would otherwise be a Distribution Date) upon which
the Certificateholders may surrender their Certificates to the Trustee for
payment of the final distribution and cancellation, shall be given promptly by
the Trustee upon the Trustee receiving notice of such date from the NIMS
Insurer, the Majority Class CE Certificateholders or the Servicer, as
applicable, by letter to the Certificateholders mailed not earlier than the 15th
day of the month preceding the month of such final distribution and not later
than the 15th day of the month of such final distribution specifying (1) the
Distribution Date upon which final distribution of the Certificates will be made
upon presentation and surrender of such Certificates at the office or agency of
the Trustee therein designated, (2) the amount of any such final distribution
and (3) that the Record Date otherwise applicable to such Distribution Date is
not applicable, distributions being made only upon presentation and surrender of
the Certificates at the office or agency of the Trustee therein specified. Not
less than five (5) Business Days prior to such Determination Date relating to
such Distribution Date, the Trustee shall notify the Originator and the Seller
of the amount of any unpaid Reimbursement Amount owed to the Trust.

            (c) Upon presentation and surrender of the Certificates, the Trustee
shall cause to be distributed to the Holders of the Certificates on the
Distribution Date for such final distribution, in proportion to the Percentage
Interests of their respective Class and to the extent that funds are available
for such purpose, an amount equal to the amount required to be distributed to
such Holders in accordance with the provisions of Sections 4.01 and 4.02 for
such Distribution Date.

            (d) In the event that all Certificateholders shall not surrender
their Certificates for final payment and cancellation on or before such final
Distribution Date, the Trustee shall promptly following such date cause all
funds in the Distribution Account not distributed in final distribution to
Certificateholders to be withdrawn therefrom and credited to the remaining
Certificateholders by depositing such funds in a separate escrow account for the
benefit of such Certificateholders, and the Servicer shall give a second written
notice to the remaining Certificateholders, to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
nine months after the second notice all the Certificates shall not have been
surrendered for cancellation, the Class R Certificateholder shall be entitled to
all unclaimed funds and other assets which remain subject hereto (except with
respect to the Class CE and Class P Certificates) and the Trustee upon transfer
of such funds shall be discharged of any responsibility for such funds, and all
other Certificateholders shall look to the Class R Certificateholder for
payment.

            Section 10.02 Additional Termination Requirements.

            (a) In the event that the NIMS Insurer, the Majority Class CE
Certificateholders or the Servicer, as applicable, exercise its purchase option
as provided in Section 10.01, the Trust shall be terminated in accordance with
the following additional requirements, unless the Trustee shall have been
furnished with an Opinion of Counsel to the effect that the failure of the Trust
to comply with the requirements of this Section will not (i) result in the
imposition of taxes on "prohibited transactions" of the Trust as defined in
Section 860F of the Code or (ii) cause any REMIC constituting part of the Trust
Fund to fail to qualify as a REMIC at any time that any Certificates (other than
the Class P Certificates) are outstanding:

            (i) The Trustee shall designate a date within 90 days prior to the
      final Distribution Date as the date of adoption of plans of complete
      liquidation of each of REMIC 1 and REMIC 2 and shall specify such date in
      the final federal income tax return of each REMIC;

            (ii) After the date of adoption of such plans of complete
      liquidation and at or prior to the final Distribution Date, the Trustee
      shall sell all of the assets of the Trust to the Majority Class CE
      Certificateholders or the Servicer, as applicable, 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 in the order of priority set forth in Section 4.02
      and then to the Class R Certificateholder, all cash on hand in respect of
      the REMICs after such payment (other than cash retained to meet claims)
      and the Trust shall terminate at such time.

            (b) By their acceptance of Certificates, the Holders thereof hereby
agree to appoint the Trustee as their attorney in fact to: (i) designate such
date of adoption of plans of complete liquidation and (ii) to take such other
action in connection therewith as may be reasonably required to carry out such
plans of complete liquidation all in accordance with the terms hereof.

                                   ARTICLE XI

                            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 the Certificateholders, (i) to cure any ambiguity or mistake,
(ii) to correct, modify or supplement any provision herein which may be
inconsistent with any other provision herein or the Prospectus Supplement, (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, (iv) to comply with any requirements imposed by the Code or (v) to
provide for the rights of the NIMS Insurer; provided, however, that any such
action listed in clause (iii) above shall not adversely affect in any respect
the interests of any Certificateholder, as evidenced by (i) notice in writing to
the Depositor, the Servicer and the Trustee from the Rating Agencies that such
action will not result in the reduction or withdrawal of the rating of any
outstanding Class of Certificates with respect to which it is a Rating Agency,
or (ii) an Opinion of Counsel delivered to the Servicer and the Trustee.

            In addition, 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 the Majority Certificateholders 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 or waiver shall (x) reduce in any
manner the amount of, or delay the timing of, payments on the Certificates which
are required to be made on any Certificate without the consent of the Holder of
such Certificate, (y) adversely affect in any material respect the interests of
the Holders of any Class of Certificates in a manner other than as described in
clause (x) above, without the consent of the Holders of Certificates of such
Class evidencing at least 51% of the Voting Rights evidenced by such Class, or
(z) reduce the percentage of Voting Rights required by clause (y) above without
the consent of the Holders of all Certificates of such Class then outstanding.
Upon approval of an amendment, a copy of such amendment shall be sent to the
Rating Agencies. Prior to the execution of any amendment to this Agreement, the
Trustee shall be entitled to receive and rely upon an Opinion of Counsel (at the
expense of the Person seeking such amendment) stating that the execution of such
amendment is authorized or permitted by this Agreement. The Trustee may, but
shall not be obligated to, enter into any such amendment which affects the
Trustee's own rights, duties or immunities under this Agreement.

            Notwithstanding any provision of this Agreement to the contrary,
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, delivered
by (and at the expense of) the Person seeking such Amendment, to the effect that
such amendment will not result in the imposition of a tax on any REMIC
constituting part of the Trust Fund pursuant to the REMIC Provisions or cause
any REMIC constituting part of the Trust Fund to fail to qualify as a REMIC at
any time that any Certificates (other than the Class P Certificates) are
outstanding and that the amendment is being made in accordance with the terms
hereof.

            Promptly after the execution of any such amendment the Trustee shall
furnish, at the expense of the Person that requested the amendment if such
Person is the Servicer (but in no event at the expense of the Trustee),
otherwise at the expense of the Trust, a copy of such amendment and the Opinion
of Counsel referred to in the immediately preceding paragraph to the Servicer
and each Rating Agency.

            It shall not be necessary for the consent of Certificateholders
under this Section 11.01 to approve the particular form of any proposed
amendment; instead 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.

            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 Trust, but only upon direction of
Certificateholders, 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 together constitute but
one and the same instrument.

            Section 11.03 Limitation on Rights of Certificateholders.

            The death or incapacity of any Certificateholder shall not (i)
operate to terminate this Agreement or the Trust, (ii) 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, or (iii) otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

            Except as expressly provided for herein, no Certificateholder shall
have any right to vote 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 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 herein 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 60 days after
its receipt of such notice, request and offer of indemnity, shall have neglected
or refused to institute any such action, suit or proceeding. It 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 whatever 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, which priority or
preference is not otherwise provided for herein, 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 11.03 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; Jurisdiction.

            This Agreement shall be construed in accordance with the laws of the
State of New York, and the obligations, rights and remedies of the parties

claim arising out of this Agreement, each party irrevocably submits to the
exclusive jurisdiction of the courts of the State of New York and the United
States District Court located in the Borough of Manhattan in The City of New
York, and each party irrevocably waives any objection which it may have at any
time to the laying of venue of any suit, action or proceeding arising out of or
relating hereto brought in any such courts, irrevocably waives any claim that
any such suit, action or proceeding brought in any such court has been brought
in any inconvenient forum and further irrevocably waives the right to object,
with respect to such claim, suit, action or proceeding brought in any such
court, that such court does not have jurisdiction over such party, provided that
service of process has been made by any lawful means.

            Section 11.10 Third Party Beneficiary.

            The NIMS Insurer shall be deemed a third-party beneficiary of this

Certificateholders may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Certificateholders in person or by
agent duly appointed in writing; and such action shall become effective when
such instrument or instruments are delivered to the Trustee and the Servicer.
Such instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "act" of the Certificateholders
signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Agreement and conclusive in favor of the Trustee and the Trust,

by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Whenever
such execution is by a signer acting in a capacity other than his or her
individual capacity, such certificate or affidavit shall also constitute
sufficient proof of his authority.

            (c) Any request, demand, authorization, direction, notice, consent,
waiver or other action by any Certificateholder shall bind every future Holder
of such Certificate and the Holder of every Certificate issued upon the

respect of anything done, omitted or suffered to be done by the Trustee or the
Trust in reliance thereon, whether or not notation of such action is made upon

records and any other information available to such party and reasonably
necessary in the good faith determination of the Depositor to permit the

            This certifies that _______________ is the registered owner of a
Percentage Interest (obtained by dividing the Initial Certificate Principal
Balance of this Certificate by the Original Class Certificate Principal Balance
of the Class A-1 Certificates) in that certain beneficial ownership interest

to a Pooling and Servicing Agreement, dated as specified above (the
"Agreement"), among Asset Backed Funding Corporation (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 Business Day immediately preceding such

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

therein set forth, the transfer of this Certificate is registrable in the

the Certificate Registrar 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.

            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, 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 Certificate Registrar 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 the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar 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, the Certificate Registrar 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 or on behalf of 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
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all 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 the Trust Fund all 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
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the Cut-off Date Aggregate Principal Balance.

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

      INSTRUMENTALITY OF THE UNITED STATES OR ANY OTHER ENTITY.

            This certifies that _______________ is the registered owner of a

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.

related LIBOR Determination Date plus the Class A-2 Certificate Margin and (ii)

designated as ABFC Asset-Backed Certificates of the Series specified on the face
hereof (herein called the "Certificates") and representing a Percentage Interest
in the Class A-2 Certificates.

            The Class A-2 Certificates are limited in right of payment to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than 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 the Voting Rights
identified in the agreement. 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 and
the Certificate Registrar 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.

            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, 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 Certificate Registrar 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 the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar 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, the Certificate Registrar 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 or on behalf of 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
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all 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 the Trust Fund all 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
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the Cut-off Date Aggregate Principal Balance.

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

      AFFILIATES. THIS CERTIFICATE IS NOT GUARANTEED BY ANY AGENCY OR
      INSTRUMENTALITY OF THE UNITED STATES.

            This certifies that _______________ is the registered owner of a
Percentage Interest (obtained by dividing the Initial Certificate Principal
Balance of this Certificate by the Original Class Certificate Principal Balance
of the Class A-3 Certificates) in that certain beneficial ownership interest

to a Pooling and Servicing Agreement, dated as specified above (the
"Agreement"), among Asset Backed Funding Corporation (hereinafter called the
"Depositor," which term includes any successor entity under the Agreement), the

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.

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 Business Day immediately preceding such
Distribution Date (the "Record Date"), from funds in the Distribution Account 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
A-3 Certificates on such Distribution Date pursuant to the Agreement; provided,
however, that if any Class A-3 Certificate becomes a Definitive Certificate, the
Record Date for such Certificate will be the last Business Day of the month
immediately preceding the month in which the related Distribution Date occurs.

each Distribution Date will be the lesser of (i) One-Month LIBOR as of the
related LIBOR Determination Date plus the Class A-3 Certificate Margin and (ii)

designated as ABFC Asset-Backed Certificates of the Series specified on the face
hereof (herein called the "Certificates") and representing a Percentage Interest
in the Class A-3 Certificates.

            The Class A-3 Certificates are limited in right of payment to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than 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 the Voting Rights
identified in the agreement. 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 and
the Certificate Registrar 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.

            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, 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 Certificate Registrar 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 the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar 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, the Certificate Registrar 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 or on behalf of 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
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all 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 the Trust Fund all 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
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the Cut-off Date Aggregate Principal Balance.

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

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 the Voting Rights
identified in the agreement. 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 and
the Certificate Registrar 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.

            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, 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 Certificate Registrar 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.

Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar 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, the Certificate Registrar 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 or on behalf of 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
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all 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 the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as

                                     B-1-4
<PAGE>

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

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

Agreement will be made or caused to be made by or on behalf of the Trustee by
wire transfer in immediately available funds to the account of the Person
entitled thereto if such Person shall have so notified the Certificate Registrar
in writing at least five Business Days prior to the Record Date immediately
prior to such Distribution Date and is the registered owner of Class M-2
Certificates, or by check mailed by first class mail to the address of the
Person entitled thereto, as such name and address shall appear on the
Certificate Register, provided that the Certificate Registrar may deduct a
reasonable wire transfer fee from any payment made by wire transfer.
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
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.

            The Certificate Interest Rate for the Class M-2 Certificates for
each Distribution Date will be the lesser of (i) One-Month LIBOR as of the
related LIBOR Determination Date plus the Class M-2 Certificate Margin and (ii)
the Pool Cap. Interest will accrue on the Class M-2 Certificates during each
Interest Accrual Period at the Certificate Interest Rate.

            This Certificate is one of a duly authorized issue of Certificates
designated as ABFC Asset-Backed Certificates of the Series specified on the face
hereof (herein called the "Certificates") and representing a Percentage Interest
in the Class M-2 Certificates.

            The Class M-2 Certificates are limited in right of payment to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            This certificate is subordinated in right of payment to the Class A
Certificates and Class M-1 Certificates as described in the Pooling and
Servicing Agreement referred to herein.

            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 the Voting Rights
identified in the agreement. 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 and
the Certificate Registrar 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.

            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, 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 Certificate Registrar 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 the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar 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, the Certificate Registrar 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 or on behalf of 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
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as

                                     B-2-4
<PAGE>

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

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

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

M-3 Certificates on such Distribution Date pursuant to the Agreement; provided,

            All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by or on behalf of the Trustee by

entitled thereto if such Person shall have so notified the Certificate Registrar

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 the Voting Rights
identified in the agreement. 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.

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 and
the Certificate Registrar 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.

            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, 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 Certificate Registrar 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 the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar 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, the Certificate Registrar 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 or on behalf of 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
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all 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 the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as

                                     B-3-4
<PAGE>

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

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

Agreement will be made or caused to be made by or on behalf of the Trustee by
wire transfer in immediately available funds to the account of the Person

            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 the Voting Rights
identified in the agreement. 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 and
the Certificate Registrar 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.

            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, 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 Certificate Registrar 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 the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar 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, the Certificate Registrar nor any such agent shall be
affected by notice to the contrary.

thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of 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
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as

                                     B-4-4
<PAGE>

provided in the Agreement from the Trust Fund of all 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 the
Trust Fund all 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 Principal Balance of the Mortgage
Loans at the time of purchase being less than 10% of the Cut-off Date Aggregate
Principal Balance.

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

            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 and
the Certificate Registrar 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.

            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, 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 Certificate Registrar 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 the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar 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, the Certificate Registrar 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 or on behalf of 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
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all 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 the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as

                                     B-5-4
<PAGE>

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

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

to a Pooling and Servicing Agreement, dated as specified above (the
"Agreement"), among Asset Backed Funding Corporation (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

<PAGE>

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 Business Day immediately preceding such
Distribution Date (the "Record Date"), from funds in the Distribution Account 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
M-7 Certificates on such Distribution Date pursuant to the Agreement; provided,
however, that if any Class M-7 Certificate becomes a Definitive Certificate, the
Record Date for such Certificate will be the last Business Day of the month
immediately preceding the month in which the related Distribution Date occurs.

            All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by or on behalf of the Trustee by
wire transfer in immediately available funds to the account of the Person
entitled thereto if such Person shall have so notified the Certificate Registrar
in writing at least five Business Days prior to the Record Date immediately
prior to such Distribution Date and is the registered owner of Class M-7
Certificates, or by check mailed by first class mail to the address of the
Person entitled thereto, as such name and address shall appear on the
Certificate Register, provided that the Certificate Registrar may deduct a
reasonable wire transfer fee from any payment made by wire transfer.
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
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.

            The Certificate Interest Rate for the Class M-7 Certificates for
each Distribution Date will be the lesser of (i) One-Month LIBOR as of the
related LIBOR Determination Date plus the Class M-7 Certificate Margin and (ii)
the Pool Cap. Interest will accrue on the Class M-7 Certificates during each
Interest Accrual Period at the Certificate Interest Rate.

            This Certificate is one of a duly authorized issue of Certificates
designated as ABFC Asset-Backed Certificates of the Series specified on the face
hereof (herein called the "Certificates") and representing a Percentage Interest
in the Class M-7 Certificates.

            The Class M-7 Certificates are limited in right of payment to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            This certificate is subordinated in right of payment to the Class A
Certificates, Class M-1 Certificate, Class M-2 Certificates, Class M-3

            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 the Voting Rights
identified in the agreement. 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 and
the Certificate Registrar 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.

            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, 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 transfer of this Certificate shall be made unless that transfer
is made pursuant to an effective registration statement under 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 a transfer is to be made without registration
or qualification, the Certificate Registrar shall require, in order to assure
compliance with such laws, that the Certificateholder desiring to effect the
transfer and such Certificateholder's prospective transferee each execute a
representation letter in the form described by the Agreement certifying to the
Certificate Registrar the facts surrounding the transfer. None of the Depositor,
the Certificate Registrar 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 such Certificateholder desiring to effect such transfer
shall, and does hereby agree to, indemnify the Trustee, the Depositor, the
Certificate Registrar and any 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 service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar 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 the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar 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, the Certificate Registrar 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 or on behalf of 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
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all 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 the Trust Fund all 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
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the Cut-off Date Aggregate Principal Balance.

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

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 the Voting Rights
identified in the agreement. 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 and
the Certificate Registrar 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.

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

                                     C-1-3
<PAGE>

provided in the Agreement and subject to certain limitations therein set forth,
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 transfer of this Certificate shall be made unless that transfer
is made pursuant to an effective registration statement under 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 a transfer is to be made without registration
or qualification, the Certificate Registrar shall require, in order to assure
compliance with such laws, either (i) that the Certificateholder desiring to
effect the transfer and such Certificateholder's prospective transferee each
execute a representation letter in the form described by the Agreement
certifying to the Certificate Registrar the facts surrounding the transfer, or
(ii) unless such transfer is made in reliance upon Rule 144A under the 1933 Act,
that the Depositor and the Certificate Registrar receive an Opinion of Counsel
satisfactory to them that such transfer may be made without such registration or
qualification, which Opinion of Counsel shall not be an expense of the
Depositor, the Trustee or the Certificate Registrar, in their respective
capacities as such. None of the Depositor, the Certificate Registrar 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 such Certificateholder
desiring to effect such transfer shall, and does hereby agree to, indemnify the
Trustee, the Depositor, the Certificate Registrar and any 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 Certificate or any interest therein may be made to
employee benefit plans and certain other retirement plans and arrangements,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans, accounts
or arrangements are invested that are subject to the fiduciary responsibility
provisions of ERISA, Section 4975 of the Code or any materially similar
provisions of applicable federal, state or local law (collectively, "Plans") or
any person who is directly or indirectly purchasing the Certificate or interest
therein on behalf of, as named fiduciary of, as trustee of, or with assets of a
Plan.

            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 the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar 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, the Certificate Registrar 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 or on behalf of the

                                     C-1-4
<PAGE>

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 remaining in the Trust Fund, and (ii)
the purchase by the party designated in the Agreement at a price determined as
provided in the Agreement from the Trust Fund of all 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 the
Trust Fund all 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 Principal Balance of the Mortgage
Loans at the time of purchase being less than 10% of the Cut-off Date Aggregate
Principal Balance.

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

            This certifies that __________________________________ is the
registered owner of a Percentage Interest set forth above in that certain
beneficial ownership interest evidenced by all the Class P Certificates in the
Trust Fund created pursuant to a Pooling and Servicing Agreement, dated as
specified above (the "Agreement"), among Asset Backed Funding Corporation
(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 last Business Day of the month immediately
preceding the month in which the related Distribution Date occurs (the "Record
Date"), from Prepayment Charges, Originator Prepayment Charge Payment Amounts
and Servicer Prepayment Charge Payment Amounts in the Distribution Account 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 P
Certificates on such Distribution Date pursuant to the Agreement.

                                     C-2-2
<PAGE>

            All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by or on behalf of the Trustee by

entitled thereto if such Person shall have so notified the Certificate Registrar
in writing at least five Business Days prior to the Record Date immediately
prior to such Distribution Date and is the registered owner of Class P
Certificates, or by check mailed by first class mail to the address of the
Person entitled thereto, as such name and address shall appear on the
Certificate Register, provided that the Certificate Registrar may deduct a
reasonable wire transfer fee from any payment made by wire transfer.
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
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 ABFC Asset-Backed Certificates of the Series specified on the face
hereof (herein called the "Certificates") and representing the Percentage
Interest specified on the face hereof.

            The Class P Certificates are limited in right of payment to
Prepayment Charges received on the Mortgage Loans, Originator Prepayment Charge
Payment Amounts and Servicer Prepayment Charge Payment Amounts, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than 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 the Voting Rights
identified in the agreement. 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 and
the Certificate Registrar 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.

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

                                     C-2-3
<PAGE>

provided in the Agreement and subject to certain limitations therein set forth,
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 transfer of this Certificate shall be made unless that transfer
is made pursuant to an effective registration statement under 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 a transfer is to be made without registration
or qualification, the Certificate Registrar shall require, in order to assure
compliance with such laws, either (i) that the Certificateholder desiring to
effect the transfer and such Certificateholder's prospective transferee each
execute a representation letter in the form described by the Agreement
certifying to the Certificate Registrar the facts surrounding the transfer, or
(ii) unless such transfer is made in reliance upon Rule 144A under the 1933 Act,
that the Depositor and the Certificate Registrar receive an Opinion of Counsel
satisfactory to them that such transfer may be made without such registration or
qualification, which Opinion of Counsel shall not be an expense of the
Depositor, the Trustee or the Certificate Registrar, in their respective
capacities as such. None of the Depositor, the Certificate Registrar 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 such Certificateholder
desiring to effect such transfer shall, and does hereby agree to, indemnify the
Trustee, the Depositor, the Certificate Registrar and any 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 Certificate or any interest therein may be made to
employee benefit plans and certain other retirement plans and arrangements,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans, accounts
or arrangements are invested that are subject to the fiduciary responsibility
provisions of ERISA, Section 4975 of the Code or any materially similar
provisions of applicable federal, state or local law (collectively, "Plans") or
any person who is directly or indirectly purchasing the Certificate or interest
therein on behalf of, as named fiduciary of, as trustee of, or with assets of a
Plan.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar 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 the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar 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, the Certificate Registrar or 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 or on behalf of the

                                     C-2-4
<PAGE>

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 remaining in the Trust Fund, and (ii)
the purchase by the party designated in the Agreement at a price determined as
provided in the Agreement from the Trust Fund of all 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 the
Trust Fund all 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 Principal Balance of the Mortgage
Loans at the time of purchase being less than 10% of the Cut-off Date Aggregate
Principal Balance.

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

            This Certificate is one of a duly authorized issue of Certificates
designated as ABFC Asset-Backed Certificates of the Series specified on the face
hereof (herein called the "Certificates") and representing the Percentage
Interest specified on the face hereof.

            The Class R Certificate is limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than 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 the Voting Rights
identified in the agreement. 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 and
the Certificate Registrar 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.

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

limitations therein set forth, 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 transfer of this Certificate shall be made unless that transfer
is made pursuant to an effective registration statement under 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 a transfer is to be made without registration
or qualification, the Certificate Registrar shall require, in order to assure
compliance with such laws, either (i) that the Certificateholder desiring to
effect the transfer and such Certificateholder's prospective transferee each
execute a representation letter in the form described by the Agreement
certifying to the Certificate Registrar the facts surrounding the transfer, or
(ii) unless such transfer is made in reliance upon Rule 144A under the 1933 Act,
that the Depositor and the Certificate Registrar receive an Opinion of Counsel
satisfactory to them that such transfer may be made without such registration or
qualification, which Opinion of Counsel shall not be an expense of the
Depositor, the Trustee or the Certificate Registrar, in their respective
capacities as such. None of the Depositor, the Certificate Registrar 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 such Certificateholder
desiring to effect such transfer shall, and does hereby agree to, indemnify the
Trustee, the Depositor, the Certificate Registrar and any 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 or any interest therein may be made
to employee benefit plans and certain other retirement plans and arrangements,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans, accounts
or arrangements are invested that are subject to the fiduciary responsibility
provisions of ERISA, Section 4975 of the Code or any materially similar
provisions of applicable federal, state or local law (collectively, "Plans") or
any person who is directly or indirectly purchasing the Certificate or interest
therein on behalf of, as named fiduciary of, as trustee of, or with assets of a
Plan.

            The Holder of this Certificate, by its acceptance hereof, shall be
deemed for all purposes 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
to cease to qualify as five separate REMICs or cause the imposition of a tax
upon the Trust.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar 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 the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar 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, the Certificate Registrar 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 or on behalf of 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
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all 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 the Trust Fund all 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
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the Cut-off Date Aggregate Principal Balance.

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

designated as ABFC Asset-Backed Certificates of the Series specified on the face

Interest specified on the face hereof.

collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account

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 the Voting Rights
identified in the agreement. 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 and
the Certificate Registrar 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.

            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, 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 transfer of this Certificate shall be made unless that transfer
is made pursuant to an effective registration statement under 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 a transfer is to be made without registration
or qualification, the Certificate Registrar shall require, in order to assure
compliance with such laws, either (i) that the Certificateholder desiring to
effect the transfer and such Certificateholder's prospective transferee each
execute a representation letter in the form described by the Agreement
certifying to the Certificate Registrar the facts surrounding the transfer, or
(ii) unless such transfer is made in reliance upon Rule 144A under the 1933 Act,
that the Depositor and the Certificate Registrar receive an Opinion of Counsel
satisfactory to them that such transfer may be made without such registration or
qualification, which Opinion of Counsel shall not be an expense of the
Depositor, the Trustee or the Certificate Registrar, in their respective
capacities as such. None of the Depositor, the Certificate Registrar 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 such Certificateholder
desiring to effect such transfer shall, and does hereby agree to, indemnify the
Trustee, the Depositor, the Certificate Registrar and any 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 or any interest therein may be made
to employee benefit plans and certain other retirement plans and arrangements,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans, accounts
or arrangements are invested that are subject to the fiduciary responsibility
provisions of ERISA, Section 4975 of the Code or any materially similar
provisions of applicable federal, state or local law (collectively, "Plans") or
any person who is directly or indirectly purchasing the Certificate or interest
therein on behalf of, as named fiduciary of, as trustee of, or with assets of a
Plan.

            The Holder of this Certificate, by its acceptance hereof, shall be
deemed for all purposes 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
to cease to qualify as five separate REMICs or cause the imposition of a tax
upon the Trust.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar 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 the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar 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, the Certificate Registrar 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 or on behalf of 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
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all 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 the Trust Fund all 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
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the Cut-off Date Aggregate Principal Balance.

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

COUNTY OF               )

            The undersigned, being first duly sworn, deposes and says as
follows:

            1. The undersigned is [an officer of] , the proposed Transferee of
an Ownership Interest in the [Class R][Class R-X] Certificates (the
"Certificate") issued pursuant to the Pooling and Servicing Agreement, (the
"Agreement"), relating to the above-referenced Certificates, among Asset Backed
Funding Corporation, as depositor, [___________], as servicer, and Wells Fargo
Bank, N.A., as trustee (the "Trustee"). Capitalized terms used, but not defined
herein shall have the meanings ascribed to such terms in the Agreement. The
Transferee has authorized the undersigned to make this affidavit on behalf of
the Transferee.

            2. The Transferee is, as of the date hereof, and will be, as of the
date of the Transfer, a Permitted Transferee. The Transferee is acquiring its
Ownership Interest in the Certificates either (i) for its own account or (ii) as
nominee, trustee or agent for another Person and has attached hereto an
affidavit from such Person in substantially the same form as this affidavit. The
Transferee has no knowledge that any such affidavit is false.

            3. The Transferee has been advised of, and understands that (i) a
tax will be imposed on Transfers of the Certificate to Persons that are
Disqualified Organization; (ii) such tax will be imposed on the transferor, or,
if such Transfer is through an agent (which includes a broker, nominee or
middleman) for a Person that is a Disqualified Organization, on the agent; and
(iii) the Person otherwise liable for the tax shall be relieved of liability for
the tax if the subsequent Transferee furnished to such Person an affidavit that
such subsequent Transferee is not a Disqualified Organization and, at the time
of Transfer, such Person does not have actual knowledge that the affidavit is
false.

            4. The Transferee has been advised of, and understands that a tax
will be imposed on a "pass-through entity" holding the Certificate if at any
time during the taxable year of the pass-through entity a Person that is a
Disqualified Organization is the record holder of an interest in such entity.
The Transferee understands that such tax will not be imposed for any period with
respect to which the record holder furnishes to the pass-through entity an
affidavit that such record holder is not a Disqualified Organization and the
pass-through entity does not have actual knowledge that such affidavit is false.
(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 and, except as may be provided in
Treasury Regulations, persons holding interests in pass-through entities as a
nominee for another Person.)

the Agreement and understands the legal consequences of the acquisition of an
Ownership Interest in the Certificate including, without limitation, the
restrictions on subsequent Transfers and the provisions regarding voiding the
Transfer and mandatory sales. The Transferee expressly agrees to be bound by and
to abide by the provisions of Section 5.02(d) of the Agreement and the
restrictions noted on the face of the Certificate. The Transferee understands
and agrees that any breach of any of the representations included herein shall
render the Transfer to the Transferee contemplated hereby null and void.

            6. The Transferee agrees to require a Transfer Affidavit from any
Person to whom the Transferee attempts to Transfer its Ownership Interest in the
Certificate, and in connection with any Transfer by a Person for whom the
Transferee is acting as nominee, trustee or agent, and the Transferee will not
Transfer its Ownership Interest or cause any Ownership Interest to be
Transferred to any Person that the Transferee knows is not a Permitted
Transferee. In connection with any such Transfer by the Transferee, the
Transferee agrees to deliver to the Trustee a certificate substantially in the
form set forth in this Exhibit L to the Agreement (a "Transferor Certificate")
to the effect that such Transferee has no actual knowledge that the Person to
which the Transfer is to be made is not a Permitted Transferee.

            7. The Transferee does not have the intention to impede the
assessment or collection of any tax legally required to be paid with respect to
the Certificate.

            8. The Transferee's taxpayer identification number is .

            9. The Transferee is a U.S. Person as defined in Code Section
7701(a)(30).

            10. The Transferee is aware that the Certificate may be a
"noneconomic residual interest" within the meaning of Treasury regulations
promulgated pursuant to 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
was to impede the assessment or collection of tax.

            11. That the Transferee will not cause income from the [Class
R][Class R-X] Certificate to be attributable to a foreign permanent
establishment or fixed base, within the meaning of an applicable income tax
treaty, of the Transferee or any other person.

            12. That, if the Transferee is purchasing the [Class R][Class R-X]
Certificate in a transfer intended to meet the safe harbor provisions of
Treasury Regulations Sections 1.860E-1(c), the Transferee has executed and
attached Attachment A hereto.

            13. The Transferee is not an employee benefit plan that is subject
to ERISA or a plan that is subject to Section 4975 of the Code or a plan or
arrangement subject to any materially similar provisions of applicable federal,
state or local law, nor are we acting on behalf of such a plan.

Check the appropriate box:

/ / The consideration paid to the Transferee to acquire the [Class R][Class R-X]
Certificate equals or exceeds the excess of (a) the present value of the
anticipated tax liabilities over (b) the present value of the anticipated
savings associated with holding such Certificate, in each case calculated in
accordance with U.S. Treasury Regulations Sections 1.860E-1(c)(7) and (8),
computing present values using a discount rate equal to the short-term Federal
rate prescribed by Section 1274(d) of the Code and the compounding period used
by the Transferee.

            OR

/ / The transfer of the [Class R][Class R-X] Certificate complies with U.S.
Treasury Regulations Sections 1.860E-1(c)(5) and (6) and, accordingly:

            (i) the Transferee is an "eligible corporation," as defined in U.S.
      Treasury Regulations Section 1.860E-1(c)(6)(i), as to which income from
      [Class R][Class R-X] Certificate will only be taxed in the United States;

            (ii) at the time of the transfer, and at the close of the
      Transferee's two fiscal years preceding the year of the transfer, the
      Transferee had gross assets for financial reporting purposes (excluding
      any obligation of a person related to the Transferee within the meaning of
      U.S. Treasury Regulations Section 1.860E-1(c)(6)(ii)) in excess of $100
      million and net assets in excess of $10 million;

      and Section 1.860E-1(c)(5) of the U.S. Treasury Regulations;

            (iv) the Transferee has determined the consideration paid to it to
      acquire the [Class R][Class R-X] Certificate based on reasonable market
      assumptions (including, but not limited to, borrowing and investment
      rates, prepayment and loss assumptions, expense and reinvestment
      assumptions, tax rates and other factors specific to the Transferee) that
      it has determined in good faith; and

            (v) in the event of any transfer of the [Class R][Class R-X]
      Certificate by the Transferee, the Transferee will require its transferee
      to complete a representation in the form of this Attachment A as a
      condition of the transferee's purchase of the [Class R][Class R-X]
      Certificate.

      Re:   ABFC Asset-Backed Certificates, Series 20 -

Ladies and Gentlemen:

            In connection with our disposition of the ABFC Asset-Backed
Certificates, Series 20 - (the "Certificates"), we certify that (a) we
understand that the Certificates have not been registered under the Securities
Act of 1933, as amended (the "Act"), and are being disposed by us in a
transaction that is exempt from the registration requirements of the Act, (b) we
have not offered or sold any Certificates to, or solicited offers to buy any
Certificates from, any person, or otherwise approached or negotiated with any
person with respect thereto, in a manner that would be deemed, or taken any
other action which would result in, a violation of Section 5 of the Act, (c) to
the extent we are disposing of the [Class R][Class R-X] Certificate, we have no
knowledge the Transferee is not a Permitted Transferee and (d) no purpose of the
proposed disposition of the [Class R][Class R-X] Certificate is to impede the
assessment or collection of tax.

any transfer pursuant to Section 2.01 hereof, the Seller further agrees, at its
own expense, on or prior to the Closing Date, (x) to indicate in its books and
records that the Mortgage Loans have been sold to the Purchaser pursuant to this
Agreement and (y) to deliver to the Purchaser and the Trustee a computer file
containing a true and complete list of all the Mortgage Loans, specifying, among

from the applicable public recording office, has been lost or is not otherwise
available, a copy of such Mortgage or power of attorney, as the case may be,
certified to be a true and complete copy of the original submitted for

            (iii) an original Assignment of Mortgage, in form and substance

            (v) the original or a certified copy of the lender's title insurance

            If any of the documents referred to in Section 2.02(ii), (iii) or
(iv) above has as of the Closing Date been submitted for recording but either
(x) has not been returned from the applicable public recording office or (y) has
been lost or such public recording office has retained the original of such

            Upon discovery or receipt of notice of any materially defective
document in, or that a document is missing from, a Mortgage File, the Seller
shall have 120 days to cure such defect or deliver such missing document to the
Trustee or 150 days following the Closing Date, in the case of missing Mortgages
or Assignments (or within 90 days of the earlier of Seller's discovery or
receipt of notification if such defect would cause the related Mortgage Loan not
to be a "qualified mortgage" for REMIC purposes or that the Mortgage Loan is
defective in a manner that would cause it to be a "defective obligation" within
the meaning of Treasury regulations relating to REMICs). If the Seller does not
cure such defect or deliver such missing document within such time period, the
Seller shall either repurchase or substitute for such Mortgage Loan in
accordance with Section 2.03 of the Pooling and Servicing Agreement.

            It is understood and agreed that the obligations of the Seller set
forth in this Section 2.02 to cure, repurchase or substitute for a defective
Mortgage Loan constitute the sole remedies of the Purchaser respecting a missing
or defective document.

            The Purchaser hereby acknowledges its acceptance of all right, title
and interest to the Mortgage Loans and other property, now existing and
hereafter created, conveyed to it pursuant to Section 2.01.

            The parties hereto intend that the transaction set forth herein be a
sale by the Seller to the Purchaser of all the Seller's right, title and
interest in and to the Mortgage Loans and other property described above. In the
event the transaction set forth herein is deemed not to be a sale, the Seller
hereby grants to the Purchaser a security interest in all of the Seller's right,
title and interest in, to and under the Mortgage Loans and other property
described above, whether now existing or hereafter created, to secure all of the
Seller's obligations hereunder; and this Agreement shall constitute a security
agreement under applicable law. The Seller and the Purchaser shall, to the
extent consistent with this Agreement, take such actions as may be necessary to
ensure that, if this Agreement were deemed to create a security interest in the
Mortgage Loans, such security interest would be deemed to be a perfected
security interest of first priority under applicable law and will be maintained
as such throughout the term of the Pooling and Servicing Agreement.

            Section 2.03 Payment of Purchase Price for the Mortgage Loans. In
consideration of the sale of the Mortgage Loans from the Seller to the Purchaser
on the Closing Date, the Purchaser agrees (i) to pay to the Seller on the
Closing Date by transfer of immediately available funds, as directed by the
Seller, an amount equal to $[_________] and (ii) deliver to or at the direction
of the Seller on the Closing Date, the Class CE, Class P, Class R and Class R-X
Certificates, in respect of the Mortgage Loans (collectively, the "Purchase
Price"). The Seller shall pay, and be billed directly for, all reasonable
expenses incurred by the Purchaser in connection with the issuance of the
Certificates, including, without limitation, printing fees incurred in
connection with the prospectus relating to the Certificates, blue sky
registration fees and expenses, fees and reasonable expenses of Purchaser's
counsel, fees of the rating agencies requested to rate the Certificates,
accountant's fees and expenses and the fees and expenses of the Trustee and
other out-of-pocket costs, if any.

            Section 2.04 Regulation AB Compliance

            For so long as the Trustee is required to file any report with the
Commission pursuant to Section 3.31 of the Pooling and Servicing Agreement, the
Seller shall furnish to the Trustee, within five (5) calendar days following
each Distribution Date, the "significance estimate" of each Yield Maintenance
Agreement calculated in accordance with Item 1115 of Regulation AB as of such
Distribution Date.

                                  ARTICLE III.

               REPRESENTATIONS AND WARRANTIES; REMEDIES FOR BREACH

            Section 3.01 Seller Representations and Warranties Relating to the
Mortgage Loans

            The representations and warranties in the Underlying Sale Agreement
were made as of [_______], 20 .

            The Seller's right, title and interest in such representations and
warranties and the remedies in connection therewith have been assigned to the
Purchaser pursuant to Section 2.01 of this Agreement. To the extent that any
fact, condition or event with respect to a Mortgage Loan constitutes a breach of
both (i) a representation or warranty of the Company under the Underlying Sale
Agreement and (ii) a representation or warranty of the Seller under this
Agreement (other than Section 3.01(k) and 3.01(t) below), the only right or
remedy of the Purchaser shall be the right to enforce the obligations of the
Company under any applicable representation or warranty made by it. The
Purchaser acknowledges and agrees that the representations and warranties of the
Seller in this Section 3.01 are applicable only to facts, conditions or events
that do not constitute a breach of any representation or warranty made by the
Company in the Underlying Sale Agreement. The Seller shall have no obligation or
liability with respect to any breach of a representation or warranty made by it
with respect to the Mortgage Loans (other than the representations made in
Section 3.01(k) below) if the fact, condition or event constituting such breach
also constitutes a breach of a representation or warranty made by the Company in
the Underlying Sale Agreement, without regard to whether the Company fulfills
its contractual obligations in respect of such representation or warranty. If,
however, the Originator fails to reimburse the Trustee for any costs or damages
incurred by the Trust in connection with a breach of the Originator's
representation set forth in Section [___] or [____] of the Underlying Sale
Agreement (such amount, the "Reimbursement Amount"), the Seller shall pay the
Reimbursement Amount to the Trust. The Reimbursement Amount shall be delivered
to the Servicer for deposit into the Collection Account within 10 days from the
date the Seller was notified by the Trustee of the amount of such costs and
damages. Subject to the foregoing, the Seller represents and warrants upon
delivery of the Mortgage Loans to the Purchaser hereunder, as to each, that:

            (a) The information set forth with respect to the Mortgage Loans on
the Mortgage Loan Schedule attached hereto as Schedule I provides an accurate
listing of the Mortgage Loans, and the information with respect to each Mortgage
Loan on the Mortgage Loan Schedule is true and correct in all material respects
at the date or dates respecting which such information is given;

            (b) No Mortgage Loan was 30 days or more contractually delinquent as
of the Cut-off Date. The Seller has not waived any default, breach, violation or
event of acceleration, and the Seller has not taken any action to waive any
default, breach, violation or event of acceleration, with respect to any
Mortgage Loan;

            (c) There are no delinquent taxes, assessments that could become a
lien prior to the related Mortgage or insurance premiums affecting the related
Mortgaged Property;

            (d) Each Mortgage has not been satisfied, canceled, subordinated or
rescinded, in whole or in part, and the related Mortgaged Property has not been
released from the lien of the Mortgage, in whole or in part, nor has any
instrument been executed that would effect any such satisfaction, cancellation,
subordination, recission or release;

            (e) Other than any Mortgage Loan that is less than 30 days
contractually delinquent as of the Cut-off Date, there is no material default,
breach, violation or event of acceleration existing under any Mortgage or the
related Mortgage Note and no event which, with the passage of time or with
notice and the expiration of any grace or cure period, would constitute a
material default, breach, violation or event of acceleration, and neither the
Seller nor its predecessors have waived any material default, breach, violation
or event of acceleration;

            (f) Each Mortgaged Property is free of material damage that would
affect adversely the value of the Mortgaged Property as security for the
Mortgage Loan or the use for which the premises were intended;

            (g) To the best of the Seller's knowledge, there is no proceeding
pending for the total or partial condemnation of the Mortgaged Property;

            (h) Each Mortgaged Property is lawfully occupied under applicable
law; all inspections, licenses and certificates required to be made or issued
with respect to all occupied portions of each Mortgaged Property and, with
respect to the use and occupancy of the same, including but not limited to
certificates of occupancy, have been made or obtained from the appropriate
authorities, except where the failure would not have a material adverse effect
upon the Mortgage Loan;

            (i) No Mortgage Loan is in foreclosure;

            (j) Each Mortgage Loan is a "qualified mortgage" within the meaning
of Section 860G of the Code and Treas. Reg ss. 1.860G-2;

            (k) Any and all requirements of any federal, state or local law
including, without limitation, usury, truth in lending, real estate settlement
procedures, consumer credit protections, all applicable predatory and abusive
lending laws, equal credit opportunity or disclosure laws applicable to the
origination of each Mortgage Loan have been complied with;

            (l) No Mortgage Loan is a "high cost" loan as defined under any
federal, state or local law applicable to such Mortgage Loan at the time of its
origination;

            (m) The Seller is the sole owner of record and holder of the
Mortgage Loan and the Mortgage Note and the Mortgage are not assigned or
pledged, and the Seller has good and marketable title thereto and has full right
and authority to transfer and sell the Mortgage Loan to the Purchaser. The
Seller is transferring the Mortgage Loan free and clear of any and all
encumbrances, liens, pledges, equities, participation interests, claims,
agreements with other parties to sell or otherwise transfer the Mortgage Loan,
mechanics' or similar liens or claims which have been filed for work, labor or
material (and no rights are outstanding that under the law could give rise to
such liens), charges or security interests of any nature encumbering such
Mortgage Loan;

            (n) The terms of the Mortgage Note and Mortgage have not been
impaired, waived, altered or modified in any respect, except by a written
instrument which has been recorded, if necessary, to protect the interests of
the Purchaser and maintain the lien priority of the Mortgage and which has been
delivered to the Purchaser or its designee. The substance of any such waiver,
alteration or modification has been approved by the title insurer, to the extent
required by the policy, and its terms are reflected on the Mortgage Loan
Schedule. No instrument of waiver, alteration or modification has been executed,
and no Mortgagor has been released, in whole or in part, except in connection
with an assumption agreement approved by the title insurer, to the extent
required by the policy, and which assumption agreement is part of the Mortgage
File delivered to the Purchaser or its designee and the terms of which are
reflected on the Mortgage Loan Schedule;

            (o) The Seller has not dealt with any broker, investment banker,
agent or other Person (other than the Company and the Underwriters) who may be
entitled to any commission or compensation in connection with the sale of the
Mortgage Loans;

            (p) The Mortgage is a valid, subsisting enforceable and perfected
first or second lien and first priority security interest on the Mortgaged
Property, including all buildings on the Mortgaged Property and all
installations and mechanical, electrical, plumbing, heating and air conditioning
systems located in or annexed to such buildings, and all additions, alterations
and replacements made at any time with respect to the foregoing. The lien of the
Mortgage is subject only to:

            (i) the lien of current real property taxes and assessments not yet
      due and payable;

            (ii) covenants, conditions and restrictions, rights of way,
      easements and other matters of the public record as of the date of
      recording acceptable to mortgage lending institutions generally and
      specifically referred to in the lender's title insurance policy delivered
      to the originator of the Mortgage Loan and (i) referred to or to otherwise
      considered in the appraisal made for the originator of the Mortgage Loan
      or (ii) which do not adversely affect the appraised value of the Mortgaged
      Property set forth in such appraisal;

            (iii) other matters to which like properties are commonly subject
      which do not materially interfere with the benefits of the security
      intended to be provided by the Mortgage or the use, enjoyment, value or
      marketability of the related Mortgaged Property; and

            (iv) with respect to each second lien Mortgage a prior mortgage lien
      on the Mortgaged Property;

            (q) The Mortgage Loan is covered by (a) an attorney's opinion of
title and abstract of title the form and substance of which is acceptable to
Fannie Mae, (b) an ALTA lender's title insurance policy or (c) a CLTA lender's
title insurance policy or (d) another generally acceptable form of policy of
insurance issued by a title insurer qualified to do business in the jurisdiction
where the Mortgaged Property is located insuring the Company, its successors and
assigns, as to the first or second priority lien of the Mortgage in the original
principal amount of the Mortgage Loan subject only to the exceptions contained
in clauses (i), (ii) and (iii), and with respect to each second lien Mortgage
Loan clause (iv), of paragraph (p) of this Section 3.01, and against any loss by
reason of the invalidity of unenforceability of the lien resulting from the
provisions of the Mortgage providing for adjustment in the Mortgage Interest
Rate and Monthly Payment. Additionally, such lender's title insurance policy
affirmatively insures ingress and egress, and against encroachments by or upon
the Mortgaged Property or any interest therein. Where required by state law or
regulation, the Mortgagor has been given the opportunity to choose the carrier
of such lender's title insurance policy. The Company, its successors and
assigns, are the sole insureds of such lender's title insurance policy, and such
lender's title insurance policy is valid and remains in full force and effect
and will be in full force and effect upon the sale of the Mortgage Loan to the
Purchaser. No claims have been made under such lender's title insurance policy,
and no prior holder of the Mortgage, including the Company or the Seller, has
done anything which would impair the coverage of such lender's title insurance
policy. In connection with the issuance of such lender's title insurance policy,
no unlawful fee, commission, kickback or other unlawful compensation or value of
any kind has been or will be received, retained or realized by any attorney,
firm or other person or entity, and no such unlawful items have been received,
retained or realized by the Company or the Seller;

            (r) Any security agreement, chattel mortgage or equivalent document
related to and delivered in connection with the Mortgage Loan establishes and
creates a valid, subsisting and enforceable (A) first lien and first priority
security interest with respect to each first lien Mortgage Loan, or (B) second
lien and second priority security interest with respect to each second lien
Mortgage Loan, in either case, on the property described therein and the Company
has full right to sell and assign the same to the Purchaser. The Mortgaged
Property was not, as of the date of origination of the Mortgage Loan, subject to
a mortgage, deed of trust, deed to secure debt or other security instrument
creating a lien subordinate to the lien of the Mortgage;

            (s) With respect to the Mortgage Loans listed on Exhibit D-1 to the
Pooling and Servicing Agreement only, and except in the case of a Mortgage Loan
with a Principal Balance at origination of less than $60,000 which would have
resulted in an unprofitable origination, no Mortgagor was charged "points and
fees" (whether or not financed) in an amount greater than 5% of the principal
amount of such loan, such 5% limitation is calculated in accordance with Fannie
Mae's anti-predatory lending requirements as set forth in the Fannie Mae Selling
Guide; and

            (t) No Mortgage Loan is a High Cost Loan or Covered Loan, as
applicable (as such terms are defined in the then-current S&P's LEVELS(R)
Glossary which is now Version 5.6(d), Appendix E) and no Mortgage Loan
originated on or after October 1, 2002 through March 6, 2003 is governed by the
Georgia Fair Lending Act.

            With respect to the representations and warranties set forth in this
Section 3.01 that are made to the best of the Seller's knowledge or as to which
the Seller has no knowledge, if it is discovered by the Purchaser, the Servicer
or the Trustee that the substance of such representation and warranty is
inaccurate and such inaccuracy materially and adversely affects the value of the
related Mortgage Loan, Prepayment Charge or the interest therein of the
Purchaser or the Purchaser's assignee, transferee or designee then,
notwithstanding the Seller's lack of knowledge with respect to the substance of
such representation and warranty being inaccurate at the time the representation
or warranty was made, such inaccuracy shall be deemed a breach of the applicable
representation or warranty.

            Upon discovery by the Seller, the Servicer, the Purchaser or any
assignee, transferee or designee of the Purchaser of a breach of any of the
representations and warranties contained in this Article III that materially and
adversely affects the value of any Mortgage Loan or the interest therein of the
Purchaser or the Purchaser's assignee, transferee or designee, the party
discovering the breach shall give prompt written notice to the others. Subject
to the first paragraph of this Section 3.01, within 90 days of the earlier of
its discovery or its receipt of notice of any such breach of a representation or
warranty, the Seller shall promptly cure such breach in all material respects,
or in the event such breach cannot be cured, the Seller shall repurchase the
affected Mortgage Loan or cause the removal of such Mortgage Loan from the Trust
Fund and substitute for it one or more Eligible Substitute Mortgage Loans, in
either case, in accordance with Section 2.03 of the Pooling and Servicing
Agreement.

            It is understood and agreed that the representations and warranties
set forth in this Section 3.01 shall survive delivery of the respective Mortgage
Files to the Trustee on behalf of the Purchaser and the Closing Date and shall
inure to the benefit of the Certificateholders notwithstanding any restrictive
or qualified endorsement or assignment.

            It is understood and agreed that the obligations of the Seller set
forth in this Section 3.01 to cure, repurchase or substitute for a Mortgage Loan
as a result of a breach of a representation or warranty, subject to the
limitation contained in the first paragraph of this Section 3.01, and to pay the
Reimbursement Amount constitute the sole remedies of the Purchaser respecting a
breach of the representations or warranties contained in this Section 3.01.

            Section 3.02 Seller Representations and Warranties. The Seller
hereby represents and warrants to the Purchaser that as of the Closing Date or

its obligations under this Agreement, (iii) the value or marketability of the
Mortgage Loans, or (iv) its ability to foreclose on the related Mortgaged

receivership, moratorium or similar laws affecting the enforcement of creditors'
rights generally or creditors of national banks and by the availability of
equitable remedies, (ii) general equity principles (regardless of whether such
enforcement is considered in a proceeding in equity or at law) or (iii) public
policy considerations underlying the securities laws, to the extent that such
policy considerations limit the enforceability of the provisions of this
Agreement which purport to provide indemnification from securities laws
liabilities.

            (c) The Seller holds all necessary licenses, certificates and
permits from all governmental authorities necessary for conducting its business
as it is presently conducted, except for such licenses, certificates and permits
the absence of which, individually or in the aggregate, would not have a

it is presently conducted. It is not required to obtain the consent of any other
party or any consent, license, approval or authorization from, or registration

may be, prior to the Closing Date.

            (d) The execution and delivery of this Agreement and the
consummation of the transactions contemplated herein (i) will not conflict with
or constitute a breach of, or default under, or result in the creation or
imposition of any lien, charge or encumbrance upon any property or assets of the
Seller pursuant to any material contract, indenture, mortgage, loan agreement,
note, lease or other instrument, agreement or document to which the Seller is a
party or by which it may be bound or to which any of the property or assets of
the Seller is subject, (ii) will not result in any violation of the provisions
of the charter or by-laws of the Seller, or any law, administrative regulation
or administrative or court decree applicable to the Seller and (iii) will not
require any filing or registration with or notice to or consent, approval,
authorization or order of any court or governmental authority or agency.

            (e) The transactions contemplated by this Agreement are in the
ordinary course of the Seller's business.

            (f) The Seller is not insolvent, nor will the Seller be made

pending insolvency.

            (g) The Seller is not in violation of, and the execution and
delivery of this Agreement by it and its performance and compliance with the
terms of this Agreement will not constitute a violation with respect to any
order or decree of any court, or any order or regulation of any federal, state,
municipal or governmental agency having jurisdiction, which violation would
materially and adversely affect the Seller's condition (financial or otherwise)
or operations or any of the Seller's properties, or materially and adversely
affect the performance of any of its duties hereunder.

            (h) There are no actions or proceedings against, or investigations
of, the Seller pending or, to its knowledge, threatened, before any court,
administrative agency or other tribunal (i) that, if determined adversely, would
prohibit the Seller from entering into this Agreement, (ii) seeking to prevent
the consummation of any of the transactions contemplated by this Agreement or
(iii) that, if determined adversely, would prohibit or materially and adversely
affect the Seller's performance of any of its respective obligations under, or
the validity or enforceability of, this Agreement.

            (i) The Seller is not transferring the Mortgage Loans to the
Purchaser hereunder with any intent to hinder, delay or defraud any of its
creditors.

            (j) The Seller acquired title to the Mortgage Loans in good faith,
without notice of any adverse claims.

            (k) The transfer, assignment and conveyance of the Mortgage Notes
and the Mortgages by the Seller pursuant to this Agreement are not subject to
the bulk transfer laws or any similar statutory provisions in effect in any
applicable jurisdiction.

                                   ARTICLE IV

                               SELLER'S COVENANTS

            Section 4.01 Covenants of the Seller .The Seller hereby covenants
that except for the transfer hereunder, the Seller will not sell, pledge, assign
or transfer to any other Person, or grant, create, incur, assume or suffer to
exist any lien on any Mortgage Loan, or any interest therein; the Seller will
notify the Trustee, as assignee of the Purchaser, of the existence of any lien
on any Mortgage Loan immediately upon discovery thereof, and the Seller will
defend the right, title and interest of the Trust, as assignee of the Purchaser,
in, to and under the Mortgage Loans, against all claims of third parties
claiming through or under the Seller; provided, however, that nothing in this
Section 4.01 shall prevent or be deemed to prohibit the Seller from suffering to
exist upon any of the Mortgage Loans any liens for municipal or other local
taxes and other governmental charges if such taxes or governmental charges shall
not at the time be due and payable or if the Seller shall currently be
contesting the validity thereof in good faith by appropriate proceedings and
shall have set aside on its books adequate reserves with respect thereto.

                                   ARTICLE V

                                   TERMINATION

            Section 5.01 Termination. The respective obligations and
responsibilities of the Seller and the Purchaser created hereby shall terminate
upon the termination of the Trust as provided in Article X of the Pooling and
Servicing Agreement.

                                   ARTICLE VI

                            MISCELLANEOUS PROVISIONS

            Section 6.01 Amendment. This Agreement may be amended from time to
time by the Seller and the Purchaser by written agreement signed by the Seller
and the Purchaser.

            Section 6.02 Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York and the
obligations, rights and remedies of the parties hereunder shall be determined in
accordance with such laws.

            Section 6.03 Notices. All demands, notices and communications
hereunder shall be in writing and shall be deemed to have been duly given if
personally delivered at or mailed by registered mail, postage prepaid, addressed
as follows:

            if to the Seller:

            Bank of America, National Association
            Bank of America Corporate Center
            100 North Tryon Street
            Charlotte, North Carolina 28255
            Attention:  General Counsel

or such other  address as may  hereafter  be  furnished  to the  Purchaser in
writing by the Seller.

            if to the Purchaser:

            Asset Backed Funding Corporation
            214 North Tryon Street
            21st Floor
            Charlotte, North Carolina 28255
            Attention:

or such other address as may hereafter be furnished to the Seller in writing by
the Purchaser.

            Section 6.04 Severability of Provisions. If any one or more of the
covenants, agreements, provisions or terms of this Agreement shall be held
invalid for any reason whatsoever, then such covenants, agreements, provisions
or terms shall be deemed severable from the remaining covenants, agreements,
provisions or terms of this Agreement and shall in no way affect the validity or
enforceability of the other provisions of this Agreement.

            Section 6.05 Counterparts. This Agreement may be executed in one or
more counterparts by the different parties hereto on separate counterparts, each
of which, when so executed, shall be deemed to be an original and such
counterparts, together, shall constitute one and the same agreement.

            Section 6.06 Further Agreements. The Purchaser and the Seller each
agree to execute and deliver to the other such additional documents, instruments
or agreements as may be necessary or reasonable and appropriate to effectuate
the purposes of this Agreement or in connection with the issuance of any Series
of Certificates representing interests in the Mortgage Loans.

            Without limiting the generality of the foregoing, as a further
inducement for the Purchaser to purchase the Mortgage Loans from the Seller, the
Seller will cooperate with the Purchaser in connection with the sale of any of
the securities representing interests in the Mortgage Loans. In that connection,
the Seller will provide to the Purchaser any and all information and appropriate
verification of information, whether through letters of its auditors and counsel
or otherwise, as the Purchaser shall reasonably request and will provide to the
Purchaser such additional representations and warranties, covenants, opinions of
counsel, letters from auditors, and certificates of public officials or officers
of the Seller as are reasonably required in connection with such transactions
and the offering of investment grade securities rated by the Rating Agencies.

            Section 6.07 Intention of the Parties. It is the intention of the
parties that the Purchaser is purchasing, and the Seller is selling, the
Mortgage Loans rather than the pledging of the Mortgage Loans by the Seller to
secure a loan by the Purchaser to the Seller. Accordingly, the parties hereto
each intend to treat the transaction for Federal income tax purposes and all
other purposes as a sale by the Seller and a purchase by the Purchaser of the
Mortgage Loans. The Purchaser will have the right to review the Mortgage Loans
and the related Mortgage Files to determine the characteristics of the Mortgage
Loans which will affect the Federal income tax consequences of owning the
Mortgage Loans and the Seller will cooperate with all reasonable requests made
by the Purchaser in the course of such review.

            Section 6.08 Successors and Assigns; Assignment of this Agreement.
This Agreement shall bind and inure to the benefit of and be enforceable by the
Seller, the Purchaser and the Trustee. The obligations of the Seller under this
Agreement cannot be assigned or delegated to a third party without the consent
of the Purchaser and which consent shall be at the Purchaser's sole discretion,
except that the Purchaser acknowledges and agrees that the Seller may assign its
obligations hereunder to any Person into which the Seller is merged or any
corporation resulting from any merger, conversion or consolidation to which the
Seller is a party or any Person succeeding to the business of the Seller. The
parties hereto acknowledge that the Purchaser is acquiring the Mortgage Loans
for the purpose of contributing them to a trust that will issue a series of
certificates representing undivided interests in such Mortgage Loans. As an
inducement to the Purchaser to purchase the Mortgage Loans, the Seller
acknowledges and consents to the assignment by the Purchaser to the Trustee of
all of the Purchaser's rights against the Seller pursuant to this Agreement
insofar as such rights relate to Mortgage Loans transferred to the Trustee and
