            ASSET BACKED FUNDING CORPORATION, as depositor (the "Depositor"),
WELLS FARGO BANK, N.A., as master servicer (in such capacity, the "Master
Servicer") and as securities administrator (in such capacity, the "Securities
Administrator"), and JPMORGAN CHASE BANK, NATIONAL ASSOCIATION, as trustee (the
"Trustee"), are entering into this Pooling and Servicing Agreement, dated as of
March 1, 2005 (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 twenty-two
Classes of Certificates, designated as (i) the Class A-1SS, Class A-1MZ, Class
A-2SS, Class A-2MZ, Class A-3A, Class A-3B and Class A-3C Certificates, (ii) the
Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7,
Class M-8 and Class M-9 Certificates, (iii) the Class B-1, Class B-2 and Class
B-3 Certificates, (iv) the Class CE Certificates, (v) the Class P Certificates
and (vi) the Class R Certificate.

                                   REMIC 1

            As provided herein, the Securities Administrator 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.

      (iv)  an original copy of any intervening assignment of Mortgage showing a
            complete chain of assignments and for each Mortgage Loan that is a
            MERS Mortgage Loan but is not a MOM Mortgage Loan, the original
            assignment showing MERS or its designee as the assignee of the
            Mortgage;

      (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 (or Custodians on behalf of 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 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 (or Custodians on behalf of 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 (or Custodians on behalf of the Trustee) promptly upon receipt thereof
of either the original or a copy of such document certified by the applicable
public recording office to be a true and complete copy of the original. The
Depositor shall deliver or cause to be delivered to the Trustee (or Custodians
on behalf of 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.

            With respect to any MERS Mortgage Loan, the Master Servicer shall
cause the applicable Servicer to take all actions as are necessary to cause the
Trust to be shown as the owner of the related Mortgage Loan on the records of
MERS for the purpose of the system of recording transfers of beneficial
ownership of mortgages maintained by MERS.

            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 Custodians on behalf of 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 (or Custodians on
behalf of the Trustee), executed copies of the Servicing Agreements, the
Accredited Sale Agreement and the Mortgage Loan Purchase Agreement.

            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 (or receipt by the Custodian on
its behalf) 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 required to be delivered
pursuant to 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 (or Custodians on behalf of 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 constituting part of such Mortgage File (other than such documents
described in Section 2.01(iv) or (vi)) required to be delivered to it pursuant
to 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), (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 (or Custodians on behalf of 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
(or Custodians on behalf of the Trustee) shall deliver to the Depositor, the
Master Servicer, the applicable Servicer, the Securities Administrator 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
(or Custodians on behalf of the Trustee) finds any document or documents
constituting a part of a Mortgage File to be missing or defective in any
material respect, at the conclusion of its review the Trustee (or Custodians on
behalf of the Trustee) shall so notify the Seller, the Depositor, the NIMS
Insurer, the Master Servicer and the Securities Administrator. In addition, upon
the discovery by the applicable Originator, the Seller, the Depositor, the NIMS
Insurer, the Custodians, the Trustee, the Securities Administrator or the Master
Servicer (or upon receipt by the Trustee or a Custodian of written notification
of such breach) of a breach of any of the representations and warranties made by
an Originator in the applicable Originator Sale 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 Securities Administrator is hereby directed to execute and
deliver, on behalf of the Trust, the Class A-1 Yield Maintenance Agreement,
Class A-2 Yield Maintenance Agreement, Class A-3 Yield Maintenance Agreement and
Class M/B Yield Maintenance Agreement.

            Section 2.03  Repurchase or Substitution of Mortgage Loans by an
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 an Originator or the Seller of any representation or warranty
under the related Originator Sale 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 applicable Originator or the Seller, as the case may be, the Master
Servicer, the applicable 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 breach of a representation or warranty, request the
applicable Originator or the Seller, as applicable, cure such breach within 90
days from the date the applicable 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 applicable Originator or the Seller, as
the case may be, does not cure such breach in all material respects during such
period, the Trustee shall enforce the applicable Originator's or the Seller's
obligation, as the case may be, under the related Originator Sale Agreement or
the Mortgage Loan Purchase Agreement, as applicable, and cause the applicable
Originator or the Seller, as the case may be, 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
Master Servicer Custodial Account, and the Trustee (or applicable Custodian on
behalf of the Trustee), upon receipt of written notice from the Master Servicer
of such deposit, shall release to the applicable 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
applicable Originator or the Seller, as applicable, shall furnish to it and as
shall be necessary to vest in such 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 applicable 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 Sale Agreements and the Mortgage Loan Purchase Agreement that are
made to the best of the applicable Originator's or the Seller's knowledge, as
the case may be, or as to which the applicable Originator or the Seller, as the
case may be, has no knowledge, if it is discovered by the Depositor, the Master
Servicer, the NIMS Insurer, the Securities Administrator 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 applicable 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 Sale Agreements and the Mortgage Loan Purchase
Agreement shall survive delivery of the Mortgage Files to the Trustee (or
Custodians on behalf of 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 Originators and the Seller set forth in this Section 2.03(a) to cure,
substitute for or repurchase a Mortgage Loan pursuant to the related Originator
Sale Agreement and 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 related Originator Sale
Agreement and the Mortgage Loan Purchase Agreement.

            The representations and warranties of the Originators with respect
to the Originator Sale Agreements, which have been assigned to the Trustee
hereunder, were made as of the dates specified in the Originator Sale
Agreements. To the extent that any fact, condition or event with respect to a
Mortgage Loan constitutes a breach of both (i) a representation or warranty of
the applicable Originator under the applicable Originator Sale 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 Sections 3.01(k) and 3.01(t) 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
applicable 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 an Originator in
the related Originator Sale Agreement without regard to whether the applicable
Originator fulfills its contractual obligations in respect of such
representation or warranty. In addition, the related Originator shall be
obligated to pay the Reimbursement Amount relating to such Mortgage Loan, and,
to the extent such Originator fails to do so, the Trustee shall be entitled to
enforce the Seller's obligation to pay such Reimbursement Amount.

            (b) Within 90 days of the earlier of discovery by the Master
Servicer or receipt of notice by the Master Servicer of the breach of any
representation, warranty or covenant of the Master Servicer set forth in Section
2.05 which materially and adversely affects the interests of the
Certificateholders in any Mortgage Loan, the Master 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 an Originator or the Seller substitutes an
Eligible Substitute Mortgage Loan or Loans, such substitution shall be effected
by such Originator or the Seller, as applicable, delivering to the Trustee (or
applicable Custodian on behalf of the Trustee) for such Eligible Substitute
Mortgage Loan or Loans, the documents and agreements, with all necessary
endorsements thereon, as are required by Section 2.01, together with an
Officers' Certificate of the Seller 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 (or applicable Custodian on behalf of 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 Master Servicer, the applicable
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 (or applicable Custodian on behalf of the
Trustee) shall deliver to the Master Servicer, the applicable 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 applicable Originator or the Seller, as
the case may be. 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 applicable
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 Mortgage Loan Schedules 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, the Master Servicer, the
Custodians 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 an Originator or the Seller, the applicable
Originator Sale Agreement or the Mortgage Loan Purchase Agreement, as the case
may be, including, in the case of a substitution effected by an Originator or
the Seller, all applicable representations and warranties thereof included in
the applicable Originator Sale Agreement or the Mortgage Loan Purchase
Agreement, as the case may be, as of the date of substitution.

            For any month in which an Originator or the Seller substitutes one
or more Eligible Substitute Mortgage Loans for one or more Defective Mortgage
Loans, the Master 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, an
Originator or the Seller, as the case may be, will deliver or cause to be
delivered to the Master Servicer for deposit in the Master Servicer Custodial
Account an amount equal to the Substitution Adjustment Amount, if any, and the
Trustee (or the applicable Custodian on behalf of the Trustee), upon receipt of
the related Eligible Substitute Mortgage Loan or Loans and notice by the Master
Servicer of such deposit, shall release to the applicable Originator or the
Seller, as the case may be, the related Mortgage File or Files and the Trustee
shall execute and deliver such instruments of transfer or assignment, in each
case without recourse, as such 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 related 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 created hereunder to fail to qualify as a REMIC at
any time that any Certificate is outstanding. If such Opinion of Counsel cannot
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 Seller, the Master Servicer, the NIMS
Insurer, the Securities Administrator, the Custodians 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 related 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 related 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 (or applicable Custodian on behalf of
the Trustee) shall reconvey to the related Originator or the Seller, as the case
may be, the Mortgage Loan to be released pursuant hereto in the same manner, and
on the same terms and conditions, as it would a Mortgage Loan repurchased for
breach of a representation or warranty.

            Section 2.04  [Reserved].

            Section 2.05  Representations, Warranties and Covenants of the
Master Servicer.

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

            (i) The Master Servicer is a national banking association duly
      chartered and validly existing in good standing under the laws of the
      United States of America and has all licenses necessary to carry on its
      business as now being conducted. The Master Servicer has 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 Master Servicer and the consummation of the
      transactions contemplated hereby have been duly and validly authorized.
      This Agreement, assuming due authorization, execution and delivery by the
      other parties hereto, evidences the valid, binding and enforceable
      obligation of the Master Servicer, subject to applicable law except as
      enforceability may be limited by (A) bankruptcy, insolvency, liquidation,
      receivership, moratorium, reorganization or other similar laws affecting
      the enforcement of the rights of creditors and (B) general principles of
      equity, whether enforcement is sought in a proceeding in equity or at law.
      All requisite corporate action has been taken by the Master Servicer to
      make this Agreement valid and binding upon the Master Servicer in
      accordance with its terms;

            (ii) No consent, approval, authorization or order is required for
      the transactions contemplated by this Agreement from any court,
      governmental agency or body, or federal or state regulatory authority
      having jurisdiction over the Master Servicer is required or, if required,
      such consent, approval, authorization or order has been or will, prior to
      the Closing Date, be obtained;

            (iii) The consummation of the transactions contemplated by this
      Agreement are in the ordinary course of business of the Master Servicer
      and will not result in the breach of any term or provision of the articles
      of incorporation or by-laws of the Master 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 Master Servicer or its property is subject, or result in the
      violation of any law, rule, regulation, order, judgment or decree to which
      the Master Servicer or its property is subject;

            (iv) This Agreement, and all documents and instruments contemplated
      hereby which are executed and delivered by the Master Servicer, constitute
      and will constitute valid, legal and binding obligations of the Master
      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 Master 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 Master 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 Master Servicer, or in any material impairment of the right
      or ability of the Master Servicer to carry on its business substantially
      as now conducted, or in any material liability on the part of the Master
      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 Master Servicer contemplated herein, or that would
      be likely to impair materially the ability of the Master Servicer to
      perform under the terms of this Agreement; and

            (vii) No consent, approval or order of any court or governmental
      agency or body is required for the execution, delivery and performance by
      the Master Servicer of or compliance by the Master Servicer with this
      Agreement or the consummation of the transactions contemplated by this
      Agreement, except for such consents, approvals, authorizations and orders,
      if any, that have been obtained.

            It is understood and agreed that the representations, warranties and
covenants set forth in this Section 2.05 shall survive delivery of the Mortgage
Files to the Trustee (or Custodians on behalf of the Trustee) and shall inure to
the benefit of the Trustee, the Depositor, the Securities Administrator, the
NIMS Insurer and the Certificateholders. Upon discovery by any of the Depositor,
the Master Servicer, the NIMS Insurer, the Securities Administrator 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 Securities Administrator, the
Master 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

                       ADMINISTRATION AND MASTER SERVICING
                                OF THE TRUST FUND

            Section 3.01  Master Servicer to Act as Master Servicer.

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

            The relationship of the Master Servicer (and of any successor to the
Master Servicer as master servicer under this Agreement) to the Trustee and the
Securities Administrator under this Agreement is intended by the parties to be
that of an independent contractor and not that of a joint venturer, partner or
agent.

            Section 3.02  Monitoring of Servicers.

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

            (b) The Master Servicer, for the benefit of the Trustee and the
Certificateholders, shall enforce the obligations of each Servicer under the
related Servicing Agreement, and shall, in the event that a Servicer fails to
perform its obligations in accordance with the related Servicing Agreement,
subject to the preceding paragraph, terminate the rights and obligations of such
Servicer thereunder and act as successor Servicer of the related Mortgage Loans
under the applicable Servicing Agreement or enter into a new servicing agreement
with a successor Servicer selected by the Master Servicer; provided, however, it
is understood and acknowledged by the parties hereto that there will be a period
of transition (not to exceed 90 days) before the actual servicing functions can
be fully transferred to such successor Servicer. Such enforcement, including,
without limitation, the legal prosecution of claims, termination of Servicing
Agreements and the pursuit of other appropriate remedies, shall be in such form
and carried out to such an extent and at such time as the Master Servicer, in
its good faith business judgment, would require were it the owner of the related
Mortgage Loans. The Master Servicer shall pay the costs of such enforcement at
its own expense, provided that the Master Servicer shall not be required to
prosecute or defend any legal action except to the extent that the Master
Servicer shall have received reasonable indemnity for its costs and expenses in
pursuing such action. Notwithstanding the foregoing, if a Servicer fails to make
any required Advance pursuant to the related Servicing Agreement, the Master
Servicer shall (i) unless the Master Servicer determines that such Advance would
not be recoverable in its good faith business judgment, make such Advance not
later than the Business Day preceding the related Distribution Date and (ii) to
the extent such failure leads to the termination of the Servicer and the Master
Servicer enters into a new servicing agreement with a successor Servicer
selected by the Master Servicer, until such time as a successor Servicer is
appointed, continue to make Advances required pursuant to the related Servicing
Agreement for any Distribution Date, within the same time frame set forth in (i)
above, unless the Master Servicer determines (to the extent provided in the
related Servicing Agreement) that such Advance would not be recoverable.

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

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

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

            Section 3.03  Maintenance of Primary Mortgage Insurance Policy;
Claims.

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

            (b) The Master Servicer agrees to cause each Servicer (to the extent
required under the related Servicing Agreement) to present, on behalf of the
Trustee and the Certificateholders, claims to the insurer under any primary
mortgage insurance policies and, in this regard, to take such reasonable action
as shall be necessary to permit recovery under any primary mortgage insurance
policies respecting defaulted Mortgage Loans. Pursuant to Sections 3.07 and
3.08, any amounts collected by the Master Servicer or any Servicer under any
Primary Mortgage Insurance Policies shall be deposited in the Master Servicer
Custodial Account, subject to withdrawal pursuant to Sections 3.07 and 3.08.

            Section 3.04  Rights of the Depositor, the Securities Administrator
and the Trustee in Respect of the Master Servicer.

            The Depositor may, but is not obligated to, enforce the obligations
of the Master Servicer hereunder and may, but is not obligated to, perform, or
cause a designee to perform, any defaulted obligation of the Master Servicer
hereunder and in connection with any such defaulted obligation to exercise the
related rights of the Master Servicer hereunder; provided that the Master
Servicer shall not be relieved of any of its obligations hereunder by virtue of
such performance by the Depositor or its designee. None of the Securities
Administrator, the Trustee or the Depositor shall have any responsibility or
liability for any action or failure to act by the Master Servicer nor shall the
Securities Administrator, the Trustee or the Depositor be obligated to supervise
the performance of the Master Servicer hereunder or otherwise.

            Section 3.05  Trustee to Act as Master Servicer.

            If the Master Servicer shall for any reason no longer be the Master
Servicer hereunder (including by reason of an Event of Default), the Trustee
shall within 90 days of such time, assume, if it so elects, or shall appoint a
successor Master Servicer to assume, all of the rights and obligations of the
Master Servicer hereunder arising thereafter.

            The predecessor Master Servicer shall, upon request of the Trustee,
but at the expense of the predecessor Master Servicer, deliver to the assuming
party all master servicing documents and records and an accounting of amounts
collected or held by it and otherwise use its best efforts to effect the orderly
and efficient transfer of such substitute documentation and records to the
assuming party. The Trustee shall be entitled to be reimbursed from the Master
Servicer (or the Trust if the Master Servicer is unable to fulfill its
obligations hereunder) for all Master Servicing Transfer Costs.

            Section 3.06  Collection Accounts.

            The Master Servicer shall enforce the obligation of each Servicer to
establish and maintain a Collection Account in accordance with the applicable
Servicing Agreement, with records to be kept with respect thereto on a Mortgage
Loan by Mortgage Loan basis, into which accounts shall be deposited within 48
hours (or as of such other time specified in the related Servicing Agreement) of

Condemnation Proceeds, Prepayment Charges, Originator Prepayment Charge Payment
Amounts, Servicer Prepayment Charge Payment Amounts, Reimbursement Amounts and

funds (less servicing compensation as permitted by the applicable Servicing
Agreement) and all other amounts to be deposited in the applicable Collection
Account. The Master Servicer is hereby authorized to make withdrawals from and
deposits to the related Collection Account for purposes required or permitted by
this Agreement.

            Section 3.07  Master Servicer Custodial Account, Distribution
Account and Reserve Accounts.

            (a) The Master Servicer shall establish and maintain the Master
Servicer Custodial Account, which shall be an Eligible Account. The Master

            M-8, Class M-9, Class B-1, Class B-2 and Class B-3 Certificates, in
            that order, and

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

            (ii) The Securities Administrator 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 Securities Administrator to the Class CE
      Certificateholder.

            (iii) Any Cap Carryover Amounts paid by the Securities Administrator
      pursuant to this Section 3.07(i) to the Offered Certificates and Private
      Class B Certificates shall be accounted for by the Securities
      Administrator as amounts paid first to the Class CE Certificates and then
      to the respective Class or Classes of Offered Certificates and Private
      Class B Certificates from the Grantor Trust. In addition, the Securities
      Administrator shall account for the Offered Certificates and Private Class
      B 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
      Private Class B Certificates.

            (iv) For federal tax return and information reporting, the right of
      the Holders of the Offered Certificates and Private Class B Certificates
      to receive payments under the Class A-1 Yield Maintenance Agreement, Class
      A-2 Yield Maintenance Agreement, Class A-3 Yield Maintenance Agreement and
      Class M/B Yield Maintenance Agreement in respect of any related Yield
      Maintenance Agreement Payments shall be assigned a value of zero.

            Section 3.08  Collection of Taxes, Assessments and Similar Items;
Escrow Accounts.

            To the extent required by the related Servicing Agreement and by the
related Mortgage Note and not violative of current law, the Master Servicer
shall require each Servicer to establish and maintain one or more escrow
accounts (for each Servicer, collectively, the "Escrow Account") and deposit and
retain therein all collections from the Mortgagors (or advances by such
Servicer) for the payment of taxes, assessments, hazard insurance premiums or
comparable items for the account of the Mortgagors. Nothing herein shall require
the Master Servicer to compel a Servicer to establish an Escrow Account in
violation of applicable law.

            Section 3.09  Permitted Withdrawals from the Master Servicer
Custodial Account and the Distribution Account.

            (a) The Master Servicer may from time to time make withdrawals from
the Master Servicer Custodial Account for the following purposes:

            (i) to pay to the Servicers (to the extent not previously retained
      by them), the Servicing Fee to which they are entitled pursuant to the
      Servicing Agreements and to pay itself any Master Servicer Custodial
      Account Reinvestment Income;

            (ii) to pay the Securities Administrator and the Trustee any amounts
      due to the Securities Administrator and the Trustee under this Agreement
      (including all amounts provided for under Section 8.05, other than the
      amounts provided for in the first sentence of Section 8.05);

            (iii) to reimburse the Servicers for unreimbursed Advances made by
      them;

            (iv) to reimburse the Servicers for any nonrecoverable Advance
      previously made;

            (v) to reimburse the Servicers for unreimbursed Servicing Advances
      made by them;

            (vi) to reimburse the Servicers for Insured Expenses from the
      related Insurance Proceeds;

            (vii) to pay to the purchaser, with respect to each Mortgage Loan or
      REO Property that has been purchased pursuant to Sections 2.01 and 2.03,
      all amounts received thereon after the date of such purchase;

            (viii) to reimburse itself and the Depositor for losses, liabilities
      and expenses incurred by any of them and reimbursable pursuant to this
      Agreement, including but not limited to, Section 3.20;

            (ix) to withdraw any amount deposited in the Master Servicer
      Custodial Account and not required to be deposited therein; and

            (x) to clear and terminate the Master Servicer Custodial Account
      upon termination of the Agreement pursuant to Section 10.01.

            (b) The Securities Administrator shall withdraw funds from the
Distribution Account for distributions to Certificateholders in the manner
specified in this Agreement.

            Section 3.10  Maintenance of Hazard Insurance.

            For each Mortgage Loan, the Master Servicer shall enforce any
obligation of the related Servicer under the applicable Servicing Agreement to
maintain or cause to be maintained fire and hazard insurance with extended
coverage customary in the area where the Mortgaged Property is located in
accordance with such Servicing Agreement. It is understood and agreed that such
insurance shall be with insurers meeting the eligibility requirements set forth
in the applicable Servicing Agreement and that no earthquake or other additional
insurance is to be required of any Mortgagor or to be maintained on property
acquired in respect of a defaulted loan, other than pursuant to such applicable
laws and regulations as shall at any time be in force and as shall require such
additional insurance.

            Pursuant to Sections 3.07 and 3.08, any amounts collected by the
Master Servicer, or by any Servicer, under any insurance policies (other than
amounts to be applied to the restoration or repair of the property subject to
the related Mortgage or released to the Mortgagor in accordance with the
applicable Servicing Agreement) shall be deposited into the Master Servicer
Custodial Account, subject to withdrawal pursuant to Section 3.09. Any cost
incurred by the Master Servicer or any Servicer in maintaining any such
insurance if the Mortgagor defaults in its obligation to do so shall be added to
the amount owing under the Mortgage Loan where the terms of the Mortgage Loan so
permit; provided, however, that the addition of any such cost shall not be taken
into account for purposes of calculating the distributions to be made to
Certificateholders and shall be recoverable by the Master Servicer or such
Servicer pursuant to Section 3.09.

            Section 3.11  Presentment of Claims and Collection of Proceeds.

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

            Section 3.12  Realization Upon Defaulted Mortgage Loans; REO
Property.

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

            (b) With respect to any REO Property, the deed or certificate of
sale shall be taken in the name of the Trust for the benefit of the
Certificateholders, or its nominee, on behalf of the Certificateholders. The
Master Servicer shall enforce the obligation of each Servicer, to the extent
provided in the applicable Servicing Agreement, to (i) cause the Trust to be
placed on the title to such REO Property and (ii) ensure that the title to such
REO Property references this Agreement. The Master Servicer shall, to the extent
provided in the applicable Servicing Agreement, cause the applicable Servicer to
sell any REO Property as expeditiously as possible and in accordance with the
provisions of this Agreement and the related Servicing Agreement, as applicable.
Pursuant to its efforts to sell such REO Property, the Master Servicer shall
cause the applicable Servicer to protect and conserve such REO Property in the
manner and to the extent required by the applicable Servicing Agreement, subject
to the REMIC Provisions.

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

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

            (e) The Liquidation Proceeds from the final disposition of the REO
Property, net of any payment to the applicable Servicer as provided above shall
be deposited in the related Collection Account on or prior to the Determination
Date in the month following receipt thereof and be remitted by wire transfer in
immediately available funds to the Master Servicer for deposit into the Master
Servicer Custodial Account.

            (f) 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 Master Servicer shall enforce the obligation of the related
Servicer to 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 such Servicer shall have applied for
and received an extension of such period from the Internal Revenue Service, in
which case the Trust Fund may continue to hold such REO Property for the period
of such extension. Notwithstanding any other provision of this Agreement, no REO
Property acquired by the Trust shall be rented (or allowed to continue to be
rented) or otherwise used for the production of income by or on behalf of the
Trust 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 either REMIC created hereunder to
the imposition of any federal, state or local income taxes on the income earned
from such Mortgaged Property under Section 860G(c) of the Code or otherwise,
unless the Master Servicer or related Servicer, as applicable, has agreed to
indemnify and hold harmless the Trust with respect to the imposition of any such
taxes.

            Section 3.13  Due-on-Sale Clauses; Assumption and Substitution
Agreements.

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

            Section 3.14  Trustee to Cooperate; Release of Files.

            (a) Upon the payment in full of any Mortgage Loan, or the receipt by
the Master Servicer or the related Servicer of a notification that payment in
full will be escrowed in a manner customary for such purposes, the Master
Servicer or the related Servicer will immediately notify the Trustee (or, at the
direction of the Trustee, the related Custodian) by delivering, or causing to be
delivered, two copies (one of which will be returned to the Servicer with the
Mortgage File) of a Request for Release (which may be delivered in an electronic
format acceptable to the Trustee (or the related Custodian) and the Master
Servicer or the related Servicer). Upon receipt of such request, the Trustee or
the related Custodian, as applicable, shall within three Business Days release
the related Mortgage File to the Master Servicer or the related Servicer. The
Trustee shall at the Master Servicer's or the related Servicer's direction
execute and deliver to the Master Servicer or the related Servicer the request
for reconveyance, deed of reconveyance or release or satisfaction of mortgage or
such instrument releasing the lien of the Mortgage, in each case provided by the
Master Servicer or the related Servicer, together with the Mortgage Note with
written evidence of cancellation thereon. If the Mortgage has been recorded in
the name of MERS or its designee, the Master Servicer shall enforce the
applicable Servicer's obligation under the related Servicing Agreement take all
necessary action to reflect the release of the Mortgage on the records of MERS.
Expenses incurred in connection with any instrument of satisfaction or deed of
reconveyance shall be chargeable to the related Mortgagor.

            (b) From time to time and as shall be appropriate for the servicing
or foreclosure of any Mortgage Loan, including for such purpose collection under
any policy of flood insurance, any fidelity bond or errors or omissions policy,
or for the purposes of effecting a partial release of any Mortgaged Property
from the lien of the Mortgage or the making of any corrections to the Mortgage
Note or the Mortgage or any of the other documents included in the Mortgage
File, the Trustee or the applicable Custodian, as applicable, shall, upon
delivery to the Trustee (or, at the direction of the Trustee, the applicable
Custodian) of a Request for Release signed by a Master Servicing Officer or a
Servicing Officer, release the Mortgage File within three Business Days to the
Master Servicer or the related Servicer. Subject to the further limitations set
forth below, the Master Servicer or the applicable Servicer shall cause the
Mortgage Files so released to be returned to the Trustee (or the applicable
Custodian on behalf of the Trustee) when the need therefor no longer exists,
unless the Mortgage Loan is liquidated and the proceeds thereof are deposited in
the applicable Collection Account, in which case such Servicer shall deliver to
the Trustee (or the applicable Custodian on behalf of the Trustee) a Request for
Release, signed by a Servicing Officer.

            (c) If the Master Servicer or any related Servicer at any time seeks
to initiate a foreclosure proceeding in respect of any Mortgaged Property as
authorized by this Agreement or the applicable Servicing Agreement, the Master
Servicer or any related Servicer shall deliver or cause to be delivered to the
Trustee, for signature, as appropriate, any court pleadings, requests for
trustee's sale or other documents necessary to effectuate such foreclosure or
any legal action brought to obtain judgment against the Mortgagor on the
Mortgage Note or the Mortgage or to obtain a deficiency judgment or to enforce
any other remedies or rights provided by the Mortgage Note or the Mortgage or
otherwise available at law or in equity.

            Section 3.15  Master Servicing Compensation.

            Master servicing compensation in the form of Master Servicer
Custodial Account Reinvestment Income shall be remitted to the Master Servicer
pursuant to Section 3.09. The Master Servicer shall be required to pay all
expenses incurred by it in connection with its master servicing activities
hereunder and shall not be entitled to reimbursement therefor except as
specifically provided in this Agreement.

            Section 3.16  Annual Statement as to Compliance.

            (a) Beginning in 2006, the Master Servicer shall deliver to the
Securities Administrator (and the Securities Administrator shall forward to the
Trustee, the NIMS Insurer and each Rating Agency), no later than March 10th of
each calendar year, an Officer's Certificate, signed by two officers of the
Master Servicer, stating, as to the signers thereof, that (a) a review of the
activities of the Master Servicer during the preceding calendar year and of the
performance of the Master Servicer under this Agreement or similar agreements
has been made under such officer's supervision, and (b) to the best of such
officer's knowledge, based on such review, the Master Servicer has fulfilled all
its obligations under this Agreement throughout such year, or, if there has been
a default in the fulfillment of any such obligation, specifying each such
default known to such officer and the nature and status thereof.

            (b) In addition, the Master Servicer shall enforce each Servicer's
obligation under the related Servicing Agreement to provide a similar statement
relating to compliance with the related Servicing Agreement.

            Section 3.17  Annual Independent Certified Public Accountants'
Reports.

            The Master Servicer shall enforce each Servicer's obligation to
provide the report required to be provided each year pursuant to Section 6.05 of
the Option One Sale and Servicing Agreement and Section 5.2(f) of the
Countrywide Servicing Agreement.

            Section 3.18  Access to Certain Documentation and Information
Regarding the Mortgage Loans.

            (a) The Master Servicer shall provide and cause each Servicer to
provide in accordance with the related Servicing Agreement to the Office of
Thrift Supervision and the FDIC and to comparable regulatory authorities
supervising Holders of Certificates and the examiners and supervisory agents of
the Office of Thrift Supervision, the FDIC and such other authorities, access to
the documentation required by applicable regulations of the Office of Thrift
Supervision and the FDIC with respect to the Mortgage Loans. Such access shall
be afforded without charge, but only upon reasonable and prior written request
and during normal business hours at the offices designated by the Master
Servicer and the related Servicer. In fulfilling such request for access, the
Master Servicer shall not be responsible to determine the sufficiency of any
information provided by such Servicer. Nothing in this Section 3.18 shall limit
the obligation of the Master Servicer and the related Servicer to observe any
applicable law and the failure of the Master Servicer or the related Servicer to
provide access as provided in this Section 3.18 as a result of such obligation
shall not constitute a breach of this Section 3.18.

            (b) The Master Servicer shall afford the NIMS Insurer, upon
reasonable advance notice, during normal business hours, access to all records
maintained by the Master Servicer in respect of its rights and obligations
hereunder and access to officers of the Master Servicer responsible for such
obligations. Upon request, the Master Servicer shall furnish to the 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 3.19  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 Agreements. The Credit Risk Manager shall look solely
to the Servicers and/or the Master 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 3.20  Liability of Master Servicer; Indemnification.

            (a) Subject to clause (b) below, the Master Servicer (except the
Trustee if it is required to succeed the Master Servicer hereunder) indemnifies
and holds the Trustee, the Securities Administrator, 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
Securities Administrator, the Depositor, the NIMS Insurer and the Trust Fund may
sustain in any way related to the failure of the Master Servicer to perform its
duties in compliance with this Agreement. The Master Servicer shall immediately
notify the Trustee, the Securities Administrator, 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 Master 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 Master Servicer,
the Trustee, the Securities Administrator, the Depositor, the NIMS Insurer
and/or the Trust Fund in respect of such claim. The provisions of this Section
3.20 shall survive the termination of this Agreement and the payment of the
outstanding Certificates.

            (b) None of the Depositor, the Master Servicer, or any of the
directors, officers, employees or agents of the Depositor or the Master Servicer
shall be under any liability to the Trust Fund or the Certificateholders for any
action taken, or for refraining from the taking of any action, in good faith
pursuant to this Agreement, or for errors in judgment; provided, however, that
this provision shall not protect the Depositor or the Master 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 Master Servicer
for a breach of its duties under 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 Master Servicer and any director, officer,
employee or agent of the Depositor or the Master 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 NIMS Insurer and any director, officer, employee
or agent of the Depositor 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. In addition, the Master Servicer and any director, officer, employee
or agent of the Master Servicer will be indemnified by the Trust and will be
held harmless against any loss, liability or expense (not including expenses,
disbursements and advances incurred or made by the Master Servicer in the
ordinary course of the Master Servicer's performance in accordance with the
provisions hereof) the Master Servicer incurs arising out of or in connection
with the acceptance or administration of its obligations and duties hereunder,
other than any loss, liability or expense (i) that constitutes a specific
liability of the Master Servicer hereunder or (ii) incurred by reason of willful
misfeasance, bad faith or negligence in the performance of the Master Servicer's
duties hereunder or by reason of reckless disregard of the Master Servicer's
obligations and duties hereunder. Neither the Depositor nor the Master 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 or the Master 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
Master Servicer's right to indemnity or reimbursement pursuant to this Section
shall survive any resignation or termination of the Master Servicer pursuant to
Section 6.03 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 3.21  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 Master Servicer, the Securities Administrator, 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 Servicers under the Credit Risk Management
Agreements 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 Agreements. 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 Servicers pursuant to the applicable
Credit Risk Management Agreements in the performance of its duties thereunder
and hereunder.

            Section 3.22  No Personal Solicitation.

            From and after the Closing Date, the Master Servicer agrees that it
will not take any action or knowingly 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 Master 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,
however, it is understood and agreed that promotions undertaken by the Master
Servicer or any of its Affiliates which 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.

            Section 3.23  Periodic Filings.

            (a) The Securities Administrator, the Trustee and the Master
Servicer shall reasonably cooperate with the Depositor in connection with the
Trust's satisfying its reporting requirements under the Exchange Act. Without
limiting the generality of the foregoing, the Securities Administrator shall
prepare on behalf of the Trust any monthly Current Reports on Form 8-K (each, a
"Monthly Form 8-K") and Annual Reports on Form 10-K (each, a "Form 10-K")
customary for similar securities as required by the Exchange Act and the rules
and regulations of the Securities and Exchange Commission thereunder, and the
Securities Administrator shall sign (other than any Form 10-K) and file (via the
Securities and Exchange Commission's Electronic Data Gathering and Retrieval
System) such forms on behalf of the Trust. The Master Servicer shall sign any
Form 10-K.

            (b) Each Monthly Form 8-K shall be filed by the Securities
Administrator within 15 days after each Distribution Date, including a copy of
the Distribution Date Statement for such Distribution Date as an exhibit
thereto. Prior to March 30th of each year (or such earlier date as may be
required by the Exchange Act and the rules and regulations of the Securities and
Exchange Commission), the Securities Administrator shall file a Form 10-K, in
substance as required by applicable law or applicable Securities and Exchange
Commission staff's interpretations. Such Form 10-K shall include as exhibits the
Master Servicer's and the Servicers' annual statement of compliance described
under Section 3.16 and the accountant's report referenced under Section 3.17, in
each case, to the extent they have been timely delivered to the Securities
Administrator. If they are not so timely delivered, the Securities Administrator
shall file an amended Form 10-K including such documents as exhibits reasonably
promptly after they are delivered to the Securities Administrator. The
Securities Administrator shall have no liability with respect to any failure to
properly prepare or file such periodic reports resulting from or relating to the
Securities Administrator's inability or failure to obtain any information not
resulting from its own negligence, willful misconduct or bad faith. The Form
10-K shall also include a certification in the form attached hereto as Exhibit O
(the "Certification"), which shall be signed by a senior officer of the Master
Servicer in charge of master servicing. The Master Servicer shall deliver the
Certification to the Securities Administrator three (3) Business Days prior to
the latest date on which the Form 10-K may be timely filed. The Securities
Administrator, the Depositor, the Trustee and the Master Servicer shall
reasonably cooperate to enable the Securities and Exchange Commission
requirements with respect to the Trust to be met in the event that the
Securities and Exchange 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 3.23, to be conducted or
allocated in a different manner.

            (c) Prior to the latest date on which the Form 10-K may be timely
filed each year, the Securities Administrator shall sign and deliver to the
Master Servicer a certification (in the form attached hereto as Exhibit P) for
the benefit of the Master Servicer and its officers, directors and Affiliates
(provided, however, that the Securities Administrator shall not undertake an
analysis of the accountant's reports attached as an exhibit to the Form 10-K).
In addition, the Securities Administrator shall also indemnify and hold harmless
the Master Servicer and its officers, directors and Affiliates from and against
any losses, damages, penalties, fines, forfeitures, reasonable and necessary
legal fees and related costs, judgments and other costs and expenses arising out
of or based upon any inaccuracy in the certification provided by the Securities
Administrator pursuant to this Section 3.23(c), any breach of the Securities
Administrator's obligations under this Section 3.23(c) or the Securities
Administrator's negligence, bad faith or willful misconduct in connection
therewith. If the indemnification provided for herein is unavailable or
insufficient to hold harmless the Master Servicer and its officers, directors
and Affiliates, then the Securities Administrator agrees that it shall
contribute to the amount paid or payable by the Master Servicer, its officers,
directors or Affiliates as a result of the losses, claims, damages or
liabilities of the Master Servicer, its officers, directors or Affiliates in
such proportion as is appropriate to reflect the relative fault of the Master
Servicer and its officers, directors and Affiliates on the one hand and the
Securities Administrator on the other in connection with a breach of the
Securities Administrator's obligations under this Section 3.23(c) or the
Securities Administrator's negligence, bad faith or willful misconduct in
connection therewith.

            (d) Upon any filing with the Securities and Exchange Commission, the
Securities Administrator shall promptly deliver to the Depositor a copy of any
such executed report, statement or information.

            (e) The obligations set forth in paragraphs (a) through (d) of this
Section shall only apply with respect to periods for which the Securities
Administrator is obligated to file reports on Form 8-K or 10-K pursuant to
paragraph (b) of this Section. On or prior to January 30, 2006, unless otherwise
requested by the Depositor, the Securities Administrator shall prepare, execute
and file with the Securities and Exchange Commission a Form 15 Suspension
Notification with respect to the Trust.

            Section 3.24  Fidelity Bond; Errors and Omissions Insurance.

            The Master Servicer shall maintain, at its own expense, a blanket
fidelity bond and an errors and omissions insurance policy, with broad coverage
on all officers, employees or other persons involved in the performance of its
obligations as Master Servicer hereunder. These policies must insure the Master
Servicer against losses resulting from dishonest or fraudulent acts committed by
the Master Servicer's personnel, any employees of outside firms that provide
data processing services for the Master Servicer, and temporary contract
employees or student interns. No provision of this Section 3.24 requiring such
fidelity bond and errors and omissions insurance shall diminish or relieve the
Master Servicer from its duties and obligations as set forth in this Agreement.
The minimum coverage under any such bond and insurance policy shall be
consistent with what is customary for a prudent master servicer. In the event
that any such policy or bond ceases to be in effect, the Master Servicer shall
obtain a comparable replacement policy or bond from an insurer or issuer,
meeting the requirements set forth above as of the date of such replacement.

                  Interest LT1B2 and REMIC 1 Regular Interest LT1B3, 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
                  principal payments that are attributable to an Aggregate
                  Overcollateralization Release Amount shall be allocated to (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 Securities Administrator 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
      Percentage of the aggregate amount of any Relief Act Interest Shortfalls
      incurred in respect of the Mortgage Loans for any Distribution Date shall
      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 LT1A1SS, REMIC 1 Regular Interest LT1A1MZ, REMIC
      1 Regular Interest LT1A2SS, REMIC 1 Regular Interest LT1A2MZ, REMIC 1
      Regular Interest LT1A3A, REMIC 1 Regular Interest LT1A3B, REMIC 1 Regular
      Interest LT1A3C, 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, REMIC 1 Regular Interest LT1M6, REMIC 1
      Regular Interest LT1M7, REMIC 1 Regular Interest LT1M8, REMIC 1 Regular
      Interest LT1M9, REMIC 1 Regular Interest LT1B1, REMIC 1 Regular Interest
      LT1B2, REMIC 1 Regular Interest LT1B3 and REMIC 1 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
      Allocation Percentage of the aggregate amount of any Relief Act Interest
      Shortfalls incurred in respect of the Mortgage Loans for any Distribution
      Date shall be allocated 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, REMIC 1 Regular
      Interest LT3SUB, REMIC 1 Regular Interest LT3GRP and to the 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) With respect to REMIC 1, any increase in principal balance due
      to a Subsequent Recovery shall be allocated as follows:

                  a. The REMIC 1 Sub WAC Allocation Percentage of Subsequent
            Recoveries shall be applied 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 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 Subsequent Recoveries shall
            be applied to such REMIC 1 Regular Interests such that the REMIC 1
            Subordinated Balance Ratio is maintained); and third, any remaining
            Subsequent Recoveries shall be allocated to REMIC 1 Regular Interest
            LT1XX; and

                  b. The REMIC 1 Marker Percentage of Subsequent Recoveries
            shall be allocated 98% to REMIC 1 Regular Interest LT1AA, 1% to
            REMIC 1 Regular Interest LT1ZZ and 1% to the REMIC 1 Regular
            Interests that are Corresponding Classes to any REMIC 2 Regular
            Interests that were increased as a result of such Subsequent
            Recovery so that the Uncertificated Principal Balance of each such
            Corresponding Class of REMIC 1 Regular Interests equals 0.5% of the
            Corresponding Class of REMIC 2 Regular Interests after taking into
            account such Subsequent Recoveries; provided, that if less than 1%
            of the REMIC Marker Percentage of Subsequent Recoveries is needed to
            restore the Corresponding Classes of REMIC 1 Regular Interests as
            described in this paragraph, any excess amount shall be allocated to
            REMIC 1 Regular Interest LT1ZZ.

            (iv) The REMIC 1 Sub WAC Allocation Percentage of all Realized
      Losses shall be applied after all distributions have been made on each
      Distribution Date first, so as to keep the Uncertificated 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
to a Subsequent Recovery that increases the Certificate Principal Balance of one
or more Classes of Subordinated Certificates shall be allocated as follows:
0.01% to REMIC 1 Regular Interest LT1GRP (in the case of a Subsequent Recovery
with respect to a Group 1 Mortgage Loan) or REMIC 1 Regular Interest LT2GRP (in
the case of a Subsequent Recovery with respect to a Group 2 Mortgage Loan) or
REMIC 1 Regular Interest LT3GRP (in the case of a Subsequent Recovery with
respect to a Group 3 Mortgage Loan); 0.01% to REMIC 1 Regular Interest LT1SUB
(in the case of a Subsequent Recovery with respect to a Group 1 Mortgage Loan)
or REMIC 1 Regular Interest LT2SUB (in the case of a Subsequent Recovery with
respect to a Group 2 Mortgage Loan) or REMIC 1 Regular Interest LT3SUB (in the
case of a Subsequent Recovery with respect to a Group 3 Mortgage Loan); 49.98%
to REMIC 1 Regular 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). Any increase
in principal balance due to a Subsequent Recovery that increases the Certificate
Principal Balance of one or more Classes of Certificates but does not increase
the Certificate Principal Balance of any Class of Subordinated Certificates
shall be allocated as follows: 0.01% to REMIC 1 Regular Interest LT1GRP (in the
case of a Subsequent Recovery with respect to a Group 1 Mortgage Loan) or REMIC
1 Regular Interest LT2GRP (in the case of a Subsequent Recovery with respect to
a Group 2 Mortgage Loan) or REMIC 1 Regular Interest LT3GRP (in the case of a
Subsequent Recovery with respect to a Group 3 Mortgage Loan); 49.99% to REMIC 1
Regular 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). To the
extent any Subsequent Recovery does not increase the balance of any Class of
Certificates, such Subsequent Recovery shall be allocated among the REMIC 1
Regular Interests as follows: 0.01% to REMIC 1 Regular Interest LT1GRP (in the
case of a Subsequent Recovery with respect to a Group 1 Mortgage Loan) or REMIC
1 Regular Interest LT2GRP (in the case of a Subsequent Recovery with respect to
a Group 2 Mortgage Loan) or REMIC 1 Regular Interest LT3GRP (in the case of a
Subsequent Recovery with respect to a Group 3 Mortgage Loan) ; 49.99% to REMIC 1
Regular Interest LT1XX; 49% to REMIC 1 Regular Interest LT1AA; and 1% to REMIC 1
Regular Interest LT1ZZ.

            (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-1SS, Class A-1MZ, Class A-2SS, Class A-2MZ,
Class A-3A, Class A-3B, Class A-3C, Class M-1, Class M-2, Class M-3, Class M-4,
Class M-5, Class M-6, Class M-7, Class M-8, Class M-9, Class B-1, Class B-2,
Class B-3, Class CE, Class P and Class R Certificates shall be substantially in
the forms annexed hereto as exhibits, and shall, on original issue, be executed
by the Securities Administrator 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 Securities
Administrator of the Trust Fund. Each Class of the Offered Certificates and
Private Class B 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 Certificate is 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 Securities Administrator 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 Securities Administrator 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 Private Class B Certificates shall be
Book-Entry Certificates. The Private Class B, Class CE, Class P and Class R
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 Securities Administrator 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 Securities
Administrator shall initially serve as Certificate Registrar for the purpose of
registering Certificates and transfers and exchanges of Certificates as herein
provided. The Securities Administrator as Certificate Registrar shall be subject
to the same standards of care, limitations on liability and rights to indemnity
as the Securities Administrator, 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 Certificate Registrar
to the same extent as they apply to the Securities Administrator. 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 Securities Administrator, the Trustee, the Master 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 Certificate,
upon satisfaction of the conditions set forth below, the Securities
Administrator 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 Securities Administrator 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 Securities Administrator or the
Certificate Registrar) be duly endorsed by, or be accompanied by a written
instrument of transfer satisfactory to the Securities Administrator 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 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 Securities Administrator except
to another Depository; (ii) the Depository shall maintain book-entry records
with respect to the Certificate Owners and with respect to ownership and
transfers of such Certificates; (iii) ownership and transfers of registration of
such Certificates on the books of the Depository shall be governed by applicable
rules established by the Depository; (iv) the Depository may collect its usual
and customary fees, charges and expenses from its Depository Participants; (v)
the Securities Administrator shall for all purposes deal with the Depository as
representative of the Certificate Owners of the Certificates for purposes of
exercising the rights of Holders under this Agreement, and requests and
directions for and votes of such representative shall not be deemed to be
inconsistent if they are made with respect to different Certificate Owners; (vi)
the Securities Administrator may rely and shall be fully protected in relying
upon information furnished by the Depository with respect to its Depository
Participants and furnished by the Depository Participants with respect to
indirect participating firms and Persons shown on the books of such indirect
participating firms as direct or indirect Certificate Owners; and (vii) the
direct participants of the Depository shall have no rights under this Agreement
under or with respect to any of the Certificates held on their behalf by the
Depository, and the Depository may be treated by the Securities Administrator
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 Securities Administrator in
writing that the Depository is no longer willing or able to discharge properly
its responsibilities as Depository and neither the Securities Administrator nor
the Depositor is able 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 Securities Administrator 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 Securities Administrator shall be liable for any delay in delivery of
such instructions and may conclusively rely on, and shall be protected in
relying on, such instructions. Upon the issuance of Definitive Certificates, the
Securities Administrator, the Certificate Registrar, the Trustee, the Master
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 Securities
Administrator, in substantially the form attached hereto as Exhibit J-2) under
the 1933 Act, the Securities Administrator 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 Securities Administrator 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 Securities Administrator or the Depositor or (ii) the Securities
Administrator 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 or Class R Certificate)
or in the form of Exhibit J-2 (in the case of the Private Class B Certificates)
acceptable to and in form and substance reasonably satisfactory to the Depositor
and the Securities Administrator certifying to the Depositor and the Securities
Administrator the facts surrounding such transfer, which investment letter shall
not be an expense of the Securities Administrator or the Depositor. The Holder
of a Private Certificate desiring to effect such transfer shall, and does hereby
agree to, indemnify the Securities Administrator 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 Securities Administrator shall have received either (i) a representation
from the transferee of such Certificate, acceptable to and in form and substance
satisfactory to the Securities Administrator and the Depositor (such requirement
is satisfied only by the Securities Administrator'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 Certificate) 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 Master Servicer, the
Securities Administrator, the Trustee or the NIMS Insurer 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 Securities Administrator by the acceptance by
a Certificate Owner of the beneficial interest in any such Class of
ERISA-Restricted Certificates, unless the Securities Administrator shall have
received from the transferee an alternative representation acceptable in form
and substance to the Depositor or an Opinion of Counsel referred to in the
preceding sentence. 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 Securities Administrator as described above shall be void
and of no effect.

            Each Person who has or who acquires any Ownership Interest in the
Class R 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 Certificate are expressly subject to the
following provisions:

            (i) Each Person holding or acquiring any Ownership Interest in the
      Class R 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
      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 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 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 Certificate.

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

            (v) If any Person other than a Disqualified Organization acquires
      any Ownership Interest in the Class R 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 Certificate or any other Person having an Ownership Interest
      therein, to notify the Depositor to arrange for the sale of the Class R
      Certificate. The proceeds of such sale, net of commissions (which may
      include commissions payable to the Depositor or its affiliates in
      connection with such sale), expenses and taxes due, if any, will be
      remitted by the Securities Administrator to the previous Holder of the
      Class R Certificate that is a Permitted Transferee, except that in the
      event that the Securities Administrator determines that the Holder of the
      Class R Certificate may be liable for any amount due under this Section or
      any other provisions of this Agreement, the Securities Administrator may
      withhold a corresponding amount from such remittance as security for such
      claim. The terms and conditions of any sale under this clause (v) shall be
      determined in the sole discretion of the Securities Administrator and it
      shall not be liable to any Person having an Ownership Interest in the
      Class R Certificate as a result of its exercise of such discretion.

            (vi) If any Person other than a Permitted Transferee acquires any
      Ownership Interest in the Class R Certificate in violation of the
      restrictions in this Section, then the Securities Administrator 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 Securities Administrator
      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 Securities Administrator, 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 Securities
Administrator or the Certificate Registrar that such Certificate has been
acquired by a bona fide purchaser, the Securities Administrator 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 Securities
Administrator 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
Securities Administrator 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 Master Servicer, the Depositor, the NIMS Insurer, the Securities
Administrator, the Trustee, the Certificate Registrar, any Paying Agent and any
agent of the Master Servicer, the Depositor, the NIMS Insurer, the Securities
Administrator, the Trustee, the Certificate Registrar or any Paying Agent 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 Master Servicer, the Trust, the NIMS Insurer, the
Securities Administrator, the Trustee or 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 Securities Administrator. 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 Securities Administrator. The Securities Administrator 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
Securities Administrator as Paying Agent shall be subject to the same standards
of care, limitations on liability and rights to indemnity as the Securities
Administrator, 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 Securities Administrator. 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 Securities Administrator, the
Trustee, the Master Servicer, the NIMS Insurer and the Depositor, such
resignation to become effective upon appointment of a successor Paying Agent.

                                   ARTICLE VI

                      THE MASTER SERVICER AND THE DEPOSITOR

            Section 6.01  Liability of the Master Servicer and the Depositor.

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

            Any entity into which the Master Servicer or the Depositor may be
merged or consolidated, or any entity resulting from any merger, conversion or
consolidation to which the Master Servicer or the Depositor shall be a party, or
any organization succeeding to the business of the Master Servicer or the
Depositor, shall be the successor of the Master 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 the that the successor or
surviving Person to the Master Servicer shall satisfy all the requirements of
Section 7.02 with respect to the qualifications of a successor servicer.

            Section 6.03  Master Servicer Not to Resign.

            Subject to the provisions of Section 7.02, the Master Servicer shall
not resign from its obligations and duties hereby imposed on it except upon
determination that its duties hereunder are no longer permissible under
applicable law. Any such determination permitting the resignation of the Master
Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to
the Securities Administrator, the Trustee and the NIMS Insurer. No such
resignation by the Master Servicer shall become effective until the Securities
Administrator, the Trustee or a successor master servicer shall have assumed the
Master Servicer's responsibilities and obligations in accordance with Section
8.05 hereof.

                                   ARTICLE VII

                                     DEFAULT

            Section 7.01  Master Servicer Event of Termination.

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

            (i) any failure by the Master Servicer to deposit amounts in the
      Distribution Account in the amount and manner provided herein so as to
      enable the Securities Administrator to distribute to Holders of
      Certificates any payment required to be made under the terms of such
      Certificates and this Agreement which continues unremedied by 3:00 P.M.
      New York time on the required date of deposit; or

            (ii) failure on the part of the Master Servicer duly to observe or
      perform in any material respect any other covenants or agreements of the
      Master Servicer set forth in the Certificates or in this Agreement, which
      covenants and agreements continue unremedied for a period of 30 days after
      the date on which written notice of such failure, requiring the same to be
      remedied, shall have been given to the Master Servicer by the Securities
      Administrator, the Trustee or the Depositor, or to the Master Servicer,
      the Depositor, the Securities Administrator and the Trustee by the Holders
      of Certificates evidencing Voting Rights aggregating not less than 25% of
      all Certificates affected thereby; or

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

            (iv) the consent by the Master Servicer to the appointment of a
      conservator or receiver or liquidator in any insolvency, readjustment of
      debt, marshalling of assets and liabilities or similar proceedings of or
      relating to the Master Servicer or of or relating to substantially all of
      its property; or the Master Servicer shall admit in writing its inability
      to pay its debts generally as they become due, file a petition to take
      advantage of any applicable insolvency or reorganization statute, make an
      assignment for the benefit of its creditors, or voluntarily suspend
      payment of its obligations.

            (b) Then, and in each and every such case, so long as a Master
Servicer Event of Termination shall not have been remedied within the applicable
grace period, 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 Master
Servicer (and to the Trustee if given by Holders of Certificates), terminate all
of the rights and obligations of the Master Servicer as master servicer under
this Agreement. Any such notice to the Master Servicer shall also be given to
the Securities Administrator, the Servicers, each Rating Agency, the NIMS
Insurer and the Depositor. On or after the receipt by the Master Servicer (and
by the Trustee if such notice is given by the Holders) of such written notice,
all authority and power of the Master 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 as successor Master Servicer pursuant to and
under this Section 7.01 and Section 7.05(a), unless and until such time as the
Trustee shall appoint a successor Master Servicer pursuant to Section 7.05, and,
without limitation, the Trustee is hereby authorized and empowered to execute
and deliver, on behalf of the Master Servicer, as attorney-in-fact or otherwise,
any and all documents and other instruments, and to do or accomplish all other
acts or things necessary or appropriate to effect the purposes of such notice of
termination. The Master Servicer agrees to cooperate with the Trustee in
effecting the termination of the responsibilities and rights of the Master
Servicer hereunder, including, without limitation, the transfer to the Trustee
for the administration by it of all cash amounts that have been deposited by the
Master Servicer in the Master Servicer Custodial Account or thereafter received
by the Master Servicer with respect to the Mortgage Loans. Upon obtaining
written notice or actual knowledge of the occurrence of any Master Servicer
Event of Termination, the Person obtaining such notice or knowledge shall give
prompt written notice thereof to Certificateholders at their respective
addresses appearing in the Certificate Register and to each Rating Agency. All
costs and expenses (including attorneys' fees) incurred in connection with
amending this Agreement to reflect such succession as Master Servicer pursuant
to this Section 7.01 shall be paid by the predecessor Master Servicer.
Notwithstanding the termination of the Master Servicer pursuant hereto, the
Master Servicer shall remain liable for any causes of action arising out of any
Master Servicer Event of Termination occurring prior to such termination.

            Section 7.02  Remedies of Trustee.

            (a) During the continuance of any Master Servicer Event of
Termination, so long as such Master Servicer Event of Termination shall not have
been remedied, the Trustee, in addition to the rights specified in Section 7.01,
shall have the right, in its own name as trustee of an express trust, to take
all actions now or hereafter existing at law, in equity or by statute to enforce
its rights and remedies and to protect the interests, and enforce the rights and
remedies, of the Certificateholders (including the institution and prosecution
of all judicial, administrative and other proceedings and the filing of proofs
of claim and debt in connection therewith). Except as otherwise expressly
provided in this Agreement, no remedy provided for by this Agreement shall be
exclusive of any other remedy, and each and every remedy shall be cumulative and
in addition to any other remedy and no delay or omission to exercise any right
or remedy shall impair any such right or remedy or shall be deemed to be a
waiver of any Master Servicer Event of Termination.

            Section 7.03  Directions by Certificateholders and Duties of Trustee
During Master Servicer Event of Termination.

            During the continuance of any Master Servicer Event of Termination,
Holders of Certificates evidencing Voting Rights aggregating not less than 25%
of each Class of Certificates affected thereby may direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred upon the Trustee under this Agreement;
provided, however, that the Trustee shall be under no obligation to pursue any
such remedy, or to exercise any of the trusts or powers vested in it by this
Agreement (including, without limitation, (a) the conducting or defending of any
administrative action or litigation hereunder or in relation hereto, and (b) the
terminating of the Master Servicer or any successor Master Servicer from its
rights and duties as servicer hereunder) at the request, order or direction of
any of the Certificateholders, unless such Certificateholders shall have offered
to the Trustee reasonable security or indemnity satisfactory to it against the
costs, expenses and liabilities which may be incurred therein or thereby and,
provided further, that, subject to the provisions of Section 8.01, the Trustee
shall have the right to decline to follow any such direction if the Trustee,
based upon an Opinion of Counsel, determines that the action or proceeding so
directed may not lawfully be taken or if the Trustee in good faith determines
that the action or proceeding so directed would subject the Trustee to a risk of
personal liability or be unjustly prejudicial to the non-assenting
Certificateholders.

            Section 7.04  Action upon Certain Failures of the Master Servicer
and upon Master Servicer Event of Termination.

            In the event that a Responsible Officer of the Trustee shall have
actual knowledge of any failure of the Master Servicer specified in Section
7.01(a)(i) or (ii) which would become an Master Servicer Event of Termination
upon the Master Servicer's failure to remedy the same after notice, the Trustee
shall give notice thereof to the Master Servicer. If a Responsible Officer of
the Trustee shall have actual knowledge of a Master Servicer Event of
Termination, the Trustee shall give prompt written notice thereof to the
Certificateholders.

            Section 7.05  Trustee to Act; Appointment of Successor.

            (a) On and after the time the Master Servicer receives a notice of
termination pursuant to Section 7.01, the Trustee (or other named successor)
shall be the successor in all respects to the Master Servicer in its capacity as
master servicer under this Agreement and the transactions set forth or provided
for herein and shall be subject to all the responsibilities, duties and
liabilities relating thereto placed on the Master Servicer by the terms and
provisions hereof or shall appoint a successor pursuant to this Section 7.05 and
the transition to such successor Master Servicer shall be fully effected within
90 days following the termination of the prior Master Servicer. Notwithstanding
the foregoing, (i) the parties hereto agree that the Trustee, in its capacity as
successor Master Servicer, immediately will assume all of the obligations of the
Master Servicer under this Agreement, (ii) the Trustee, in its capacity as
successor Master Servicer, shall not be responsible for the lack of information
and/or documents that it cannot obtain through reasonable efforts and (iii)
under no circumstances shall any provision of this Agreement be construed to
require the Trustee, acting in its capacity as successor to the Master Servicer
in its obligation to advance, expend or risk its own funds or otherwise incur
any financial liability in the performance of its duties hereunder if it shall
have reasonable grounds for believing that such funds are non-recoverable.
Subject to Section 7.05(b), as compensation therefor, the Trustee, as successor
Master Servicer, shall be entitled to such compensation as the terminated Master
Servicer would have been entitled to hereunder if no such notice of termination
had been given. Notwithstanding the above, the Trustee may, if it shall be
unwilling so to act, or shall, if it is legally unable so to act, appoint, or
petition a court of competent jurisdiction to appoint, any established housing
and home finance institution having a net worth of not less than $10,000,000 as
the successor to the terminated Master Servicer hereunder in the assumption of
all or any part of the responsibilities, duties or liabilities of the Master
Servicer hereunder; provided, however, that any such institution appointed as
successor Master Servicer shall not, as evidenced in writing by each Rating
Agency, adversely affect the then current rating of any Class of Certificates
immediately prior to the termination of the terminated Master Servicer. The
appointment of a successor Master Servicer shall not affect any liability of the
predecessor Master Servicer which may have arisen under this Agreement prior to
its termination as Master Servicer, nor shall any successor Master Servicer be
liable for any acts or omissions of the predecessor Master Servicer or for any
breach by the Master Servicer of any of its representations or warranties
contained herein or in any related document or agreement. Pending appointment of
a successor to the terminated Master Servicer hereunder, unless the Trustee is
prohibited by law from so acting, the Trustee shall act in such capacity as
provided above. The Trustee and such successor shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such
succession. All Master Servicing Transfer Costs shall be paid by the predecessor
Master Servicer upon presentation of reasonable documentation of such costs, and
if such predecessor Master Servicer defaults in its obligation to pay such
costs, such costs shall be paid by the successor Master Servicer or the Trustee
(in which case the successor Master Servicer or the Trustee shall be entitled to
reimbursement therefor from the assets of the Trust).

            (b) In connection with the appointment of a successor Master
Servicer or the assumption of the duties of the Master Servicer, as specified in
Section 7.05(a), the Trustee may make such arrangements for the compensation of
such successor as it and such successor agree.

            (c) Any successor, including the Trustee, to the Master Servicer as
master servicer shall during the term of its service as master servicer maintain
in force (i) a policy or policies of insurance covering errors and omissions in
the performance of its obligations as master servicer hereunder and (ii) a
fidelity bond in respect of its officers, employees and agents to the same
extent as the Master Servicer is so required pursuant to Section 3.24.

            Section 7.06  Notification to Certificateholders.

            Upon any termination or appointment of a successor to the Master
Servicer pursuant to this Article VII, the Securities Administrator shall give
prompt written notice thereof to Certificateholders at their respective
addresses appearing in the Certificate Register and to each Rating Agency, the
Servicers and the NIMS Insurer.

                                  ARTICLE VIII

                  THE TRUSTEE AND THE SECURITIES ADMINISTRATOR

            Section 8.01  Duties of Trustee and Securities Administrator.

            (a) The Trustee and the Securities Administrator, prior to the
occurrence of a Master Servicer Event of Termination of which a Responsible
Officer of the Trustee or the Securities Administrator, as applicable, shall
have actual knowledge and after the curing of all Master Servicer Events of
Termination which may have occurred, undertake to perform such duties and only
such duties as are specifically set forth in this Agreement, respectively. In
case a Master Servicer Event of Termination has occurred of which a Responsible
Officer of the Trustee shall have actual knowledge (which has not been cured or
waived), the Trustee shall exercise such of the rights and powers vested in it
by this Agreement, and use the same degree of care and skill in their exercise
as a reasonably prudent investor would exercise or use under the circumstances
in the conduct of such investor's own affairs. In case a Master Servicer Event
of Termination has occurred of which a Responsible Officer of the Securities
Administrator shall have actual knowledge (which has not been cured or waived),
the Securities Administrator 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 reasonably prudent investor would exercise or use under the
circumstances in the conduct of such investor's own affairs.

            The Trustee and the Securities Administrator, upon receipt of all
resolutions, certificates, statements, opinions, reports, documents, orders or
other instruments furnished to the Trustee and the Securities Administrator
which are specifically required to be furnished pursuant to any provision of
this Agreement, shall examine them to determine whether they conform on their
face to the requirements of this Agreement; provided, however, that neither the
Trustee nor the Securities Administrator shall be responsible for the accuracy
or content of any resolution, certificate, statement, opinion, report, document,
order or other instrument furnished by the Master 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 or the Securities Administrator, as the case may be, shall notify the
Certificateholders of such instrument in the event that the Trustee or the
Securities Administrator, after so requesting, does not receive a satisfactorily
corrected instrument.

            (b) No provision of this Agreement shall be construed to relieve the
Trustee or the Securities Administrator from liability for its own negligent
action, its own negligent failure to act or its own willful misfeasance;
provided, however, that:

            (i) Prior to the occurrence of a Master Servicer Event of
      Termination, and after the curing or waiver of all such Master Servicer
      Events of Termination which may have occurred, the duties and obligations
      of the Trustee and the Securities Administrator shall be determined solely
      by the express provisions of this Agreement, the Trustee and the
      Securities Administrator 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 the Securities Administrator and, in the
      absence of bad faith on the part of the Trustee or the Securities
      Administrator, as the case may be, the Trustee or the Securities
      Administrator, as applicable, 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 it by the Depositor or the
      Master Servicer and which on their face, do not contradict the
      requirements of this Agreement;

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

            (iii) The Trustee and the Securities Administrator 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
      Certificateholders or the NIMS Insurer as provided in Section 7.03;

            (iv) The Trustee shall not be charged with knowledge of a Master
      Servicer Event of Termination under clauses (a)(i) through (a)(iv) of
      Section 7.01 unless a Responsible Officer of the Trustee assigned to and
      working in the Corporate Trust Office of the Trustee obtains actual
      knowledge of such failure or event or any Responsible Officer of the
      Trustee receives written notice of such failure or event at its Corporate
      Trust Office from the Master Servicer, the Securities Administrator, the
      Depositor, the NIMS Insurer or any Certificateholder. The Securities
      Administrator shall not be charged with knowledge of any default specified
      in clauses (a)(i) and (a)(ii) of Section 7.01 or an Event of Default under
      clauses (a)(iii) and (a)(iv) of Section 7.01 unless a Responsible Officer
      of the Securities Administrator assigned to and working in the Corporate
      Trust Office of the Securities Administrator obtains actual knowledge of
      such failure or event or any Responsible Officer of the Securities
      Administrator receives written notice of such failure or event at its
      Corporate Trust Office from the Master Servicer, the Trustee, the
      Depositor, the NIMS Insurer or any Certificateholder; and

            (v) Except to the extent provided in Section 7.05 in respect of the
      Trustee as successor Master Servicer, no provision in this Agreement shall
      require the Trustee or the Securities Administrator to expend or risk its
      own funds or otherwise incur any personal financial liability in the
      performance of any of its duties as Trustee or Securities Administrator
      hereunder, or in the exercise of any of its rights or powers, if the
      Trustee or the Securities Administrator shall have reasonable grounds for
      believing that repayment of funds or adequate indemnity or security
      satisfactory to it 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 Securities Administrator to perform, or be
      responsible for the manner of performance of, any of the obligations of
      the Master Servicer under this Agreement.

            Section 8.02  Certain Matters Affecting the Trustee and the
Securities Administrator.

            (a) Except as otherwise provided in Section 8.01:

            (i) the Trustee and the Securities Administrator may request and
      rely upon, and shall be protected in acting or refraining from acting
      upon, any resolution, 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 and the Securities Administrator 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) neither the Trustee nor the Securities Administrator shall 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 or the Securities Administrator, as the case may
      be, reasonable security or indemnity against the costs, expenses and
      liabilities which may be incurred therein or thereby; the right of the
      Trustee or the Securities Administrator, as the case may be, to perform
      any discretionary act enumerated in this Agreement shall not be construed
      as a duty, and neither the Trustee nor the Securities Administrator shall
      be answerable for other than its negligence or willful misconduct in the
      performance of any such act;

            (iv) neither the Trustee nor the Securities Administrator shall 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 Master Servicer Event of
      Termination and after the curing of all Master Servicer Events of
      Termination which may have occurred, neither the Trustee nor the
      Securities Administrator shall be bound to make any investigation into the
      facts or matters stated in any resolution, certificate, statement,
      instrument, opinion, report, notice, request, consent, order, approval,
      bond or other paper or 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 or the
      Securities Administrator, as applicable, of the costs, expenses or
      liabilities likely to be incurred by it in the making of such
      investigation is, in the opinion of the Trustee or the Securities
      Administrator, as applicable, not reasonably assured to the Trustee or the
      Securities Administrator, as applicable, by the security afforded to it by
      the terms of this Agreement, the Trustee or the Securities Administrator,
      as the case may be, may require reasonable indemnity against such cost,
      expense or liability as a condition to such proceeding;

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

            (vii) the Trustee and the Securities Administrator may each 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
      neither the Trustee nor the Securities Administrator shall be responsible
      for any misconduct or negligence on the part of any such agent, attorney
      or custodian appointed by it with due care;

            (viii) the right of the Trustee or the Securities Administrator to
      perform any discretionary act enumerated in this Agreement shall not be
      construed as a duty, and neither the Trustee nor the Securities
      Administrator shall be answerable for other than its negligence or willful
      misconduct in the performance of such act; and

            (ix) the Trustee shall not be be liable for special, indirect or
      consequential loss or damage of any kind.

Liable for Certificates or Mortgage Loans.

            The recitals contained herein and in the Certificates (other than
the signature of the Securities Administrator on the Certificates) shall be
taken as the statements of the Depositor, and neither the Trustee nor the
Securities Administrator assumes any responsibility for the correctness of the
same. Neither the Trustee nor the Securities Administrator makes any
representations as to the validity or sufficiency of this Agreement or of the
Certificates (other than the signature of the Securities Administrator on the
Certificates) or of any Mortgage Loan or Related Document. Neither the Trustee
nor the Securities Administrator shall be accountable for the use or application
by the Master Servicer, or for the use or application of any funds paid to the
Master Servicer in respect of the Mortgage Loans or deposited in or withdrawn
from the Distribution Account by the Master Servicer. Neither the Trustee nor
the Securities Administrator shall 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 Master 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 Master Servicer pursuant to Section 7.02); the
compliance by the Depositor or the Master 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 or
Securities Administrator's receipt of written notice or actual knowledge of any
non-compliance therewith or any breach thereof; any investment of monies by or
at the direction of the Master Servicer or any loss resulting therefrom, it
being understood that the Trustee and the Securities Administrator shall remain
responsible for any Trust property that they may hold in their individual
capacity; the acts or omissions of any of the Master Servicer (other than if the
Trustee shall assume the duties of the Master Servicer pursuant to Section
7.02), or any Mortgagor; any action of the Master Servicer (other than if the
Trustee shall assume the duties of the Master Servicer pursuant to Section
7.02), taken in the name of the Trustee or the Securities Administrator; the
failure of the Master Servicer to act or perform any duties required of it as
agent of the Trustee hereunder; or any action by the Trustee or the Securities
Administrator taken at the instruction of the Master Servicer (other than if the
Trustee shall assume the duties of the Master Servicer pursuant to Section
7.02); provided, however, that the foregoing shall not relieve the Trustee and
the Securities Administrator of their obligation to perform their respective
duties under this Agreement. Neither the Trustee nor the Securities
Administrator shall 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 them
hereunder.

            Section 8.04  Trustee and Securities Administrator May Own
Certificates.

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

            Section 8.05  Securities Administrator's Fees and Expenses and
Trustee Fees and Expenses.

            The Securities Administrator and the Trustee, as compensation for
their respective services hereunder, shall each be entitled to a fee in an
amount agreed upon between the Master Servicer and either the Securities
Administrator or the Trustee, as applicable, payable by the Master Servicer out
of its own funds and not out of any funds of the Trust Fund. The Trust shall
reimburse the Trustee and the Securities Administrator for all reasonable
expenses, disbursements and advances incurred or made by the Trustee or the
Securities Administrator, as the case may be, in accordance with any of the
provisions of this Agreement (including the reasonable compensation and the
expenses and disbursements of their counsel and of all persons not regularly in
their 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 or Securities Administrator, as the case may be, hereunder. In
addition, the Trustee and the Securities Administrator and their 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
arising out of or in connection with any claim or legal action relating to the
acceptance or administration of their respective obligations and duties under
this Agreement, other than any loss, liability or expense incurred by reason of
willful misfeasance, bad faith or negligence of the Trustee or the Securities
Administrator, as the case may be, in the performance of its duties hereunder or
by reason of its reckless disregard of obligations and duties hereunder.
Further, each Custodian and their 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 arising out of or in connection
with any claim or legal action relating to the acceptance or administration of
their respective obligations and duties under this Agreement or any Custodial
Agreement, other than any loss, liability or expense incurred by reason of
willful misfeasance, bad faith or negligence of such Custodian in the
performance of its duties hereunder or under the applicable Custodial Agreement
or by reason of its reckless disregard of obligations and duties hereunder or
under the applicable Custodial Agreement. This Section shall survive termination
of this Agreement or the resignation or removal of any Trustee, Securities
Administrator or Custodian hereunder.

            Section 8.06  Eligibility Requirements for Trustee and the
Securities Administrator.

            The Trustee and the Securities Administrator 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 Fitch and S&P
and a long term debt rating of at least "A1" or better by Moody's and subject to
supervision or examination by federal or state authority. The Trustee shall not
be an affiliate of the Depositor or the Master Servicer. 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 and
the Securities Administrator (other than the initial Trustee or Securities
Administrator) shall be in a state with respect to which an Opinion of Counsel
has been delivered to such Trustee at the time such Trustee or Securities
Administrator is appointed Trustee or Securities Administrator 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 or the Securities Administrator shall cease to be
eligible in accordance with the provision of this Section 8.06, the Trustee or
the Securities Administrator, as the case may be, shall resign immediately in
the manner and with the effect specified in Section 8.07.

            Section 8.07  Resignation or Removal of Trustee and the Securities
Administrator.

            The Trustee or the Securities Administrator may at any time resign
and be discharged from the trusts hereby created by giving written notice
thereof to the Depositor, the Master Servicer, the Servicers, the NIMS Insurer
and each Rating Agency. Upon receiving such notice of resignation, the Depositor
shall promptly appoint a successor Trustee or Securities Administrator, as
applicable, reasonably acceptable to the NIMS Insurer by written instrument, in
duplicate, one copy of which instrument shall be delivered to the resigning
Trustee or Securities Administrator, as applicable, and one copy to the
successor Trustee or Securities Administrator, as the case may be. If no
successor Trustee or Securities Administrator, as applicable, shall have been so
appointed and having accepted appointment within 30 days after the giving of
such notice of resignation, the resigning Trustee or Securities Administrator,
as applicable, may petition any court of competent jurisdiction for the
appointment of a successor Trustee or Securities Administrator, as applicable.

            If at any time the Trustee or Securities Administrator shall cease
to be eligible in accordance with the provisions of Section 8.05 and shall fail
to resign after written request therefor by the Master Servicer or the NIMS
Insurer, or if at any time the Trustee or the Securities Administrator shall
become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a
receiver of the Trustee or the Securities Administrator or of their respective
property shall be appointed, or any public officer shall take charge or control
of the Trustee or the Securities Administrator or of their respective property
or affairs for the purpose of rehabilitation, conservation or liquidation, then
the Master Servicer or the NIMS Insurer may remove the Trustee or the Securities
Administrator, as the case may be, and appoint a successor Trustee or Securities
Administrator, as applicable, by written instrument, in duplicate, one copy of
which instrument shall be delivered to the Trustee or the Securities
Administrator, as applicable, so removed and one copy to the successor Trustee
or the Securities Administrator, as applicable.

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

            Any resignation or removal of the Trustee or the Securities
Administrator and appointment of a successor Trustee pursuant to any of the
provisions of this Section 8.07 shall become effective upon acceptance of
appointment by the successor Trustee or Securities Administrator, as the case
may be, as provided in Section 8.08

            Section 8.08  Successor Trustee or Securities Administrator.

            Any successor Trustee or Securities Administrator appointed as
provided in Section 8.07 shall execute, acknowledge and deliver to the
Depositor, the NIMS Insurer, the Rating Agencies, the Master Servicer, the
Servicers and to its predecessor Trustee or Securities Administrator, as the
case may be, an instrument accepting such appointment hereunder, and thereupon
the resignation or removal of the predecessor Trustee or Securities
Administrator shall become effective, and such successor Trustee or Securities
Administrator, without any further act, deed or conveyance, shall become fully
vested with all the rights, powers, duties and obligations of its predecessor
hereunder, with like effect as if originally named as Trustee or Securities
Administrator, as the case may be. The Depositor, the Master Servicer and the
predecessor Trustee or Securities Administrator 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 or Securities
Administrator, as the case may be, all such rights, powers, duties and
obligations.

            No successor Trustee or Securities Administrator shall accept
appointment as provided in this Section 8.08 unless at the time of such
acceptance such successor Trustee or Securities Administrator, as the case may
be, shall be eligible under the provisions of Section 8.06 and the appointment
of such successor Trustee or Securities Administrator, as applicable, 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 or Securities
Administrator, as applicable, as provided in this Section 8.08, the Master
Servicer shall cooperate to mail notice of the succession of such Trustee or
Securities Administrator, as the case may be, hereunder to all Holders of
Certificates at their addresses as shown in the Certificate Register, to the
NIMS Insurer and to each Rating Agency. If the Master Servicer fails to mail
such notice within ten days after acceptance of appointment by the successor
Trustee or Securities Administrator, the successor Trustee or Securities
Administrator, as the case may be, shall cause such notice to be mailed at the
expense of the Master Servicer.

            Section 8.09  Merger or Consolidation of Trustee or Securities
Administrator.

            Any entity into which the Trustee or Securities Administrator, as
applicable, 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 or Securities Administrator, as applicable, shall be a party, or any
entity succeeding to the business of the Trustee or Securities Administrator, as
the case may be, 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.

            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
Master Servicer 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 Master 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 Master Servicer and the NIMS
Insurer. If the Master 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 Master 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 Master Servicer hereunder), the Trustee shall be
      incompetent or unqualified to perform such act or acts, in which event
      such rights, powers, duties and obligations (including the holding of
      title to 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 Master 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 Master 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 Master 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 Securities Administrator, not
in its individual capacity but solely as Securities Administrator 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
Securities Administrator in the Certificates is made and intended not as a
personal undertaking or agreement by the Securities Administrator but is made
and intended for the purpose of binding only the Trust.

            Section 8.12  Trustee or Securities Administrator 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 or the Securities
Administrator without the possession of any of the Certificates or the
production thereof in any proceeding relating thereto, and such preceding
instituted by the Trustee or the Securities Administrator shall be brought in
its own name or in its capacity as Trustee or Securities Administrator. Any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursement and advances of the Trustee or Securities
Administrator, as the case may be, or their 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 Master Servicer, the
Securities Administrator, the NIMS Insurer and each Certificateholder upon
reasonable notice during the Trustee's 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 Master Servicer, the Securities Administrator,
the NIMS Insurer, the Depositor and such Certificateholder and shall make
available to the Master Servicer, the Securities Administrator, 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 Master Servicer, the Securities Administrator, 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.

            (c) The Securities Administrator shall afford the Depositor, the
Trustee, the Master Servicer, the NIMS Insurer and each Certificateholder upon
reasonable notice during normal business hours, access to all records maintained
by the Securities Administrator in respect of its duties hereunder and access to
officers of the Securities Administrator responsible for performing such duties.
The Securities Administrator shall cooperate fully with the Master Servicer, the
Trustee, the NIMS Insurer, the Depositor and such Certificateholder and shall
make available to the Master Servicer, the Trustee, 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 Securities Administrator's duties hereunder. The
Depositor, the Trustee, the Master Servicer, the NIMS Insurer and the
Certificateholders shall not have any responsibility or liability for any action
or failure to act by the Securities Administrator and are not obligated to
supervise the performance of the Securities Administrator under this Agreement
or otherwise.

            Section 8.13  Suits for Enforcement.

            In case a Master Servicer Event of Termination or other default by
the Master 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.

            Section 8.16  Appointment of Custodian.

            Each of the Custodians are hereby appointed to act in their
respective custodial capacities and the Trustee shall have no responsibility or
liability for any act or omission of Wells Fargo Bank, N.A., as a Custodian. The
Trustee may at any time on or after the Closing Date, with the consent of the
Depositor, the Securities Administrator and the Master Servicer, appoint one or
more Custodians to hold all or a portion of the Mortgage Files as agent for the
Trustee, by entering into one or more custodial agreements in a form acceptable
to the Depositor, the Securities Administrator and the Master Servicer. Subject
to this Article VIII, the Trustee agrees to comply with the terms of each
Custodial Agreement and to enforce the terms and provisions thereof against the
Custodians for the benefit of the Certificateholders. Each Custodian shall be a
depository institution subject to supervision by federal or state authority,
shall have a combined capital and surplus of at least $10,000,000 and shall be
qualified to do business in the jurisdiction in which it holds any Mortgage
File.

                     REMIC AND GRANTOR TRUST ADMINISTRATION

            Section 9.01  REMIC Administration.

            (a) The Securities Administrator shall 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. 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 Securities Administrator 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 Securities Administrator in fulfilling
its duties hereunder. The Securities Administrator shall be entitled to
reimbursement of expenses to the extent provided in clause (i) above from the
Trust.

            (d) The Securities Administrator shall prepare or cause to be
prepared, the Trustee shall sign and the Securities Administrator shall 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 Securities Administrator.

            (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 Securities Administrator is irrevocably
designated as and shall act as attorney-in-fact and agent for such Tax Matters
Person for each REMIC. The Securities Administrator, 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
Securities Administrator, 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
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 Securities Administrator, the Trustee, the Master 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
Securities Administrator, the Master Servicer or the Holder of the Class R
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 Securities Administrator, the
Trustee, the NIMS Insurer and the Master Servicer have received an Opinion of
Counsel (at the expense of the party seeking to take such action) to the effect
that the contemplated action will not endanger such status or result in the
imposition of such a tax. In addition, prior to taking any action with respect
to any REMIC 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 Certificate will consult with the
Securities Administrator, the Trustee, the NIMS Insurer and the Master Servicer,
or their respective designees, in writing, with respect to whether such action
could cause an Adverse REMIC Event to occur with respect to such REMIC, and no
such Person shall take any such action or cause such REMIC to take any such
action as to which the Securities Administrator, the Trustee, the NIMS Insurer
or the Master 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 Securities Administrator 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 Securities Administrator, 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) None of the Securities Administrator, the Trustee or the Master
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 2005,
the Securities Administrator shall deliver to each Rating Agency and the NIMS
Insurer an Officer's Certificate stating the Securities Administrator's
compliance with the provisions of this Section 9.01.

            (l) The Securities Administrator shall treat (i) the rights of the
Offered Certificates and Private Class B 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
Private Class B Certificates and (ii) the rights of the Class CE Certificates
under the Class A-1 Yield Maintenance Agreement, Class A-2 Yield Maintenance
Agreement, Class A-3 Yield Maintenance Agreement and Class M/B 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 Securities
Administrator 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 Private Class B 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 Class A-2 Reserve Account in respect of the Class A-2
Yield Maintenance Agreement, the Class A-3 Reserve Account in respect of the
Class A-3 Yield Maintenance Agreement and the Class M/B Reserve Account in
respect of the Class M/B Yield Maintenance Agreement, and then paid to the
respective Classes of Offered Certificates and Private Class B Certificates
pursuant to the related interest rate cap agreement.

            Section 9.02  Prohibited Transactions and Activities.

            None of the Depositor, the Master Servicer, the Securities
Administrator 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 or (v) a repurchase of Mortgage Loans pursuant
to Article II 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 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 Master Servicer of its duties
and obligations set forth herein, the Master Servicer shall indemnify the Holder
of the Class R Certificate against any and all losses, claims, damages,
liabilities or expenses ("Losses") resulting from such negligence; provided,
however, that the Master Servicer shall not be liable for any such Losses
attributable to the action or inaction of the Securities Administrator, the
Depositor, the Servicers or the Holder of the Class R Certificate, as
applicable, nor for any such Losses resulting from misinformation provided by
the Holder of the Class R Certificate on which the Master Servicer has relied.
The foregoing shall not be deemed to limit or restrict the rights and remedies
of the Holder of the Class R Certificate now or hereafter existing at law or in
equity. Notwithstanding the foregoing, however, in no event shall the Master
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 Master 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  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 Private Class B 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 Securities Administrator shall furnish or cause to be furnished
(i) to the Holders of the Offered Certificates and Private Class B 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.

                                   TERMINATION

            Section 10.01  Termination.

            (a) The respective obligations and responsibilities of the Master
Servicer, the Depositor, the Securities Administrator, the Trustee and the
Certificate Registrar created hereby (other than the obligation of the
Securities Administrator to make certain payments to Certificateholders after
the final Distribution Date and the obligation of the Master Servicer to send
certain notices as hereinafter set forth) shall terminate upon notice to the
Securities Administrator 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 is affiliated with the
Seller or there is no Majority Class CE Certificateholders, the Master Servicer
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 Master Servicer of the Mortgage Loans,
or if the Master Servicer fails to act, Countrywide) 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 Master Servicer,
accrued and unpaid interest thereon at the weighted average of the Mortgage
Interest Rates in effect for 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 Master 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 Master
Servicer, or if the Master Servicer fails to act, Countrywide) 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.

            Any such purchase shall be accomplished by delivery on the
Determination Date before such Distribution Date of the Termination Price to the
Securities Administrator 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 Securities
Administrator for payment of the final distribution and cancellation, shall be
given promptly by the Securities Administrator upon the Securities Administrator
receiving notice of such date from the NIMS Insurer, the Majority Class CE
Certificateholders, the Master Servicer or Countrywide, 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 Securities
Administrator 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 Securities Administrator therein
specified. Not less than five (5) Business Days prior to such Determination Date
relating to such Distribution Date, the Securities Administrator 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
Securities Administrator 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 Securities Administrator 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 Master 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 Securities Administrator 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 Master Servicer, as applicable, exercises its purchase
option as provided in Section 10.01, the Trust shall be terminated in accordance
with the following additional requirements, unless the Securities Administrator
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 Securities Administrator 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 Securities
      Administrator shall sell all of the assets of the Trust to the Majority
      Class CE Certificateholders or the Master Servicer, as applicable, for
      cash; and

            (iii) At the time of the making of the final payment on the
      Certificates, the Securities Administrator shall distribute or credit, or
      cause to be distributed or credited 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 Securities Administrator 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 Master Servicer, the Securities Administrator 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
Master Servicer, the Securities Administrator 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 Master Servicer,
the Securities Administrator and the Trustee.

            In addition, this Agreement may be amended from time to time by the
Depositor, the Master Servicer, the Securities Administrator and the Trustee,
with the consent of 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 a majority of the Percentage
Interest in 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 and the Securities Administrator 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. Each of the Securities
Administrator and Trustee may, but shall not be obligated to, enter into any
such amendment which affects the Trustee's or Securities Administrator's, as the
case may be, own rights, duties or immunities under this Agreement.

            Notwithstanding any provision of this Agreement to the contrary,
none of the Securities Administrator, the Trustee or 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 or the Grantor Trust to fail to qualify as a grantor
trust at any time that any 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 Securities
Administrator shall furnish, at the expense of the Person that requested the
amendment if such Person is the Master 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 Master 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 Securities Administrator 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
Master 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
hereunder shall be determined in accordance with such laws. With respect to any
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 11.09  Further Assurances.

            Notwithstanding any other provision of this Agreement, none of the
Regular Certificateholders, the Securities Administrator nor the Trustee shall
have any obligation to consent to any amendment or modification of this
Agreement unless they have been provided reasonable security or indemnity
against their out-of-pocket expenses (including reasonable attorneys' fees) to
be incurred in connection therewith.

            Section 11.10  Third Party Beneficiary.

            Nothing in this Agreement or in the Certificates, expressed or
implied, shall give to any Person, other than the Certificateholders, the
parties hereto, the NIMS Insurer and each Custodian (solely for purposes of
Section 8.05) and their successors hereunder, any benefit or any legal or
equitable right, remedy or claim under this Agreement.

            The NIMS Insurer shall be deemed a third-party beneficiary of this
Agreement to the same extent as if it were a party hereto, and shall have the
right to enforce the provisions of this Agreement directly against the parties
to this Agreement.

            Further, each Custodian shall be deemed a intended third party
beneficiary with respect to Section 8.05 hereof and shall be entitled to enforce

            Section 11.11  Acts of Certificateholders.

            (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Agreement to be given or taken by the
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, the Securities
Administrator and the Master Servicer. Such instrument or instruments (and the
action embodied therein and evidenced thereby) are herein sometimes referred to

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
registration of transfer thereof or in exchange therefor or in lieu thereof, in
respect of anything done, omitted or suffered to be done by the Trustee, the
Securities Administrator or the Trust in reliance thereon, whether or not

the rights of the Certificateholders under the Agreement at any time by the
Depositor, the Master Servicer, the Securities Administrator and the Trustee

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 Securities Administrator 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 Securities Administrator 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 Master Servicer, the Securities Administrator,
the Trustee and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Securities Administrator, 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 Master
Servicer, the Securities Administrator, 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 Securities Administrator 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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes 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.



            IN WITNESS WHEREOF, the Securities Administrator has caused this
Certificate to be duly executed.

provided in the Agreement, duly endorsed by, or accompanied by an assignment in

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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the

limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing 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 Trustee and the Certificate Registrar and any agent of the Depositor, the

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 Master
Servicer, the Securities Administrator, 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 Securities Administrator 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

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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes 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.

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
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-3A Certificates on such Distribution Date pursuant to the Agreement; provided,
however, that if any Class A-3A 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 Securities
Administrator 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 A-3A 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 Securities Administrator of the pendency of such
distribution and only upon presentation and surrender of this Certificate at the
office or agency appointed by the Securities Administrator for that purpose as
provided in the Agreement.

            The Certificate Interest Rate for the Class A-3A Certificates for
each Distribution Date will be the least of (i) One-Month LIBOR as of the
related LIBOR Determination Date plus the Class A-3A Certificate Margin, (ii)
the Group 3 Maximum Rate Cap and (iii) the Group 3 Cap. Interest will accrue on
the Class A-3A 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 A-3A Certificates.

            The Class A-3A 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 Accounts, Master Servicer Custodial
Account and 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 Master Servicer, the Securities Administrator, the Trustee and
the rights of the Certificateholders under the Agreement at any time by the
Depositor, the Master Servicer, the Securities Administrator 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 Securities Administrator 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 Securities Administrator 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 Master Servicer, the Securities Administrator,
the Trustee and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Securities Administrator, 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 Master
Servicer, the Securities Administrator, 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 Securities Administrator 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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes 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.



            IN WITNESS WHEREOF, the Securities Administrator has caused this
Certificate to be duly executed.

Loan remaining in the Trust Fund, and (ii) the purchase by the party designated

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

being 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the

made upon this Certificate. The Agreement also permits the amendment thereof, in

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 Securities Administrator and the Certificate Registrar duly executed by, the

coupons in Classes and denominations representing Percentage Interests specified

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

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

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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes responsibility for their correctness.

entitled to any benefit under the Agreement or be valid for any purpose.



            IN WITNESS WHEREOF, the Securities Administrator has caused this
Certificate to be duly executed.

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 Accounts, Master Servicer Custodial
Account and Distribution Account may be made from time to time for purposes
other than distributions to Certificateholders, such purposes including

            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 Master Servicer, the Securities Administrator, the Trustee and
the rights of the Certificateholders under the Agreement at any time by the

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 Securities Administrator 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 Securities Administrator 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 Master Servicer, the Securities Administrator,
the Trustee and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Securities Administrator, 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 Master
Servicer, the Securities Administrator, 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 Securities Administrator 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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes 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.



            IN WITNESS WHEREOF, the Securities Administrator has caused this
Certificate to be duly executed.

specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Accounts, Master Servicer Custodial
Account and 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.

Certificates, Class M-1 Certificates and Class M-2 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 Master Servicer, the Securities Administrator, the Trustee and
the rights of the Certificateholders under the Agreement at any time by the
Depositor, the Master Servicer, the Securities Administrator 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 Securities Administrator 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 Securities Administrator 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 Master Servicer, the Securities Administrator,
the Trustee and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Securities Administrator, 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 Master
Servicer, the Securities Administrator, 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 Securities Administrator 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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes 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.



            IN WITNESS WHEREOF, the Securities Administrator has caused this
Certificate to be duly executed.

Agreement, withdrawals from the Collection Accounts, Master Servicer Custodial
Account and 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

herein.

            The Agreement permits, with certain exceptions therein provided, the

Depositor, the Master Servicer, the Securities Administrator, the Trustee and
the rights of the Certificateholders under the Agreement at any time by the

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

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

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 Master Servicer, the Securities Administrator,
the Trustee and the Certificate Registrar and any agent of the Depositor, the

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 Master
Servicer, the Securities Administrator, the Trustee, the Certificate Registrar

Loan remaining in the Trust Fund, and (ii) the purchase by the party designated

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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by

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 Accounts, Master Servicer Custodial
Account and Distribution Account may be made from time to time for purposes
other than distributions to Certificateholders, such purposes including

Certificates, Class M-1 Certificates, Class M-2 Certificates, Class M-3
Certificates and Class M-4 Certificates as described in the Pooling and
Servicing Agreement referred to herein.

Depositor, the Master Servicer, the Securities Administrator, the Trustee and
the rights of the Certificateholders under the Agreement at any time by the

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 Securities Administrator 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 Securities Administrator 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 Master Servicer, the Securities Administrator,
the Trustee and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Securities Administrator, 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 Master
Servicer, the Securities Administrator, 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 Securities Administrator 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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes 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.



            IN WITNESS WHEREOF, the Securities Administrator has caused this
Certificate to be duly executed.

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 Master Servicer, the Securities Administrator,
the Trustee and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Securities Administrator, 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 Master
Servicer, the Securities Administrator, 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 Securities Administrator 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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes 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.



            IN WITNESS WHEREOF, the Securities Administrator has caused this
Certificate to be duly executed.

retirement of the Certificates; however, such right to purchase is subject to

being 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes responsibility for their correctness.

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

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

            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

however, that if any Class M-8 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.

Agreement will be made or caused to be made by or on behalf of the Securities

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-8 Certificates.

            The Class M-8 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 Accounts, Master Servicer Custodial
Account and 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.

Certificates, Class M-1 Certificates, Class M-2 Certificates, Class M-3
Certificates, Class M-4 Certificates, Class M-5 Certificates, Class M-6
Certificates and Class M-7 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 Master Servicer, the Securities Administrator, the Trustee and
the rights of the Certificateholders under the Agreement at any time by the
Depositor, the Master Servicer, the Securities Administrator 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 Securities Administrator 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 Securities Administrator 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 Master Servicer, the Securities Administrator,
the Trustee and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Securities Administrator, 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 Master
Servicer, the Securities Administrator, 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 Securities Administrator 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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes 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.



            IN WITNESS WHEREOF, the Securities Administrator has caused this
Certificate to be duly executed.

Loan remaining in the Trust Fund, and (ii) the purchase by the party designated

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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the

provided in the Agreement, duly endorsed by, or accompanied by an assignment in

coupons in Classes and denominations representing Percentage Interests specified

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 Trustee and the Certificate Registrar and any agent of the Depositor, the

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 Master
Servicer, the Securities Administrator, 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 Securities Administrator 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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes 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.



            IN WITNESS WHEREOF, the Securities Administrator has caused this
Certificate to be duly executed.

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

related LIBOR Determination Date plus the Class B-2 Certificate Margin, (ii) the
Pool Maximum Rate Cap and (iii) the Pool Cap. Interest will accrue on the Class

            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 B-2 Certificates.

            The Class B-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 Accounts, Master Servicer Custodial
Account and 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 Certificates, Class M-2 Certificates, Class M-3
Certificates, Class M-4 Certificates, Class M-5 Certificates, Class M-6
Certificates, Class M-7 Certificates, Class M-8 Certificates, Class M-9
Certificates and Class B-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 Master Servicer, the Securities Administrator, the Trustee and
the rights of the Certificateholders under the Agreement at any time by the
Depositor, the Master Servicer, the Securities Administrator 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 Securities Administrator 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 Securities Administrator 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, the Securities Administrator, or the Trustee is
obligated to register or qualify the Class of Certificates specified on the face
hereof under the 1933 Act or any other securities law or to take any action not
otherwise required under the Agreement to permit the transfer of such
Certificates without registration or qualification. Any such Certificateholder
desiring to effect such transfer shall, and does hereby agree to, indemnify the
Trustee, the Securities Administrator, the Depositor, the Certificate Registrar
and any Master Servicer against any liability that may result if the transfer is
not so exempt or is not made in accordance with such federal and state laws.

            No 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 Master Servicer, the Securities Administrator,
the Trustee and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Securities Administrator, 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 Master
Servicer, the Securities Administrator, 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 Securities Administrator 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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes 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.



            IN WITNESS WHEREOF, the Securities Administrator has caused this
Certificate to be duly executed.

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

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

            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 Master Servicer, the Securities Administrator,
the Trustee and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Securities Administrator, 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 Master
Servicer, the Securities Administrator, 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 Securities Administrator 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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes 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.



            IN WITNESS WHEREOF, the Securities Administrator has caused this
Certificate to be duly executed.

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

            All distributions to the Holder of this Certificate under the

Notwithstanding the above, the final distribution on this Certificate will be

            This Certificate is one of a duly authorized issue of Certificates
designated as ABFC Mortgage Loan 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 CE 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 Accounts, Master Servicer Custodial
Account and 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 Master Servicer, the Securities Administrator, the Trustee and
the rights of the Certificateholders under the Agreement at any time by the
Depositor, the Master Servicer, the Securities Administrator 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 Securities Administrator 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 Securities Administrator 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, the Securities Administrator or the Certificate
Registrar, in their respective capacities as such. None of the Depositor, the
Certificate Registrar, the Securities Administrator or the Trustee is obligated
to register or qualify the Class of Certificates specified on the face hereof
under the 1933 Act or any other securities law or to take any action not
otherwise required under the Agreement to permit the transfer of such
Certificates without registration or qualification. Any such Certificateholder
desiring to effect such transfer shall, and does hereby agree to, indemnify the
Trustee, the Depositor, the Certificate Registrar, the Securities Administrator
and the Master Servicer against any liability that may result if the transfer is
not so exempt or is not made in accordance with such federal and state laws.

            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 Securities Administrator 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 Master Servicer, the Securities Administrator,
the Trustee and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Securities Administrator, 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 Master
Servicer, the Securities Administrator, 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 Securities Administrator 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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes 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.



            IN WITNESS WHEREOF, the Securities Administrator has caused this
Certificate to be duly executed.

Notwithstanding the above, the final distribution on this Certificate will be

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 Accounts, Master Servicer Custodial
Account and Distribution Account may be made from time to time for purposes
other than distributions to Certificateholders, such purposes including

amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Securities Administrator, the Trustee and
the rights of the Certificateholders under the Agreement at any time by the
Depositor, the Master Servicer, the Securities Administrator and the Trustee

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 Securities Administrator 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 Securities Administrator 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, the Securities Administrator or the Certificate
Registrar, in their respective capacities as such. None of the Depositor, the
Certificate Registrar, the Securities Administrator or the Trustee is obligated
to register or qualify the Class of Certificates specified on the face hereof
under the 1933 Act or any other securities law or to take any action not
otherwise required under the Agreement to permit the transfer of such
Certificates without registration or qualification. Any such Certificateholder
desiring to effect such transfer shall, and does hereby agree to, indemnify the
Trustee, the Depositor, the Certificate Registrar, the Securities Administrator
and the Master Servicer against any liability that may result if the transfer is
not so exempt or is not made in accordance with such federal and state laws.

            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 Master Servicer, the Securities Administrator,
the Trustee and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Securities Administrator, 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 Master
Servicer, the Securities Administrator, 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 Securities Administrator 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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes 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.



            IN WITNESS WHEREOF, the Securities Administrator has caused this
Certificate to be duly executed.

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 two 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 Master Servicer, the Securities Administrator,
the Trustee and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Securities Administrator, 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 Master
Servicer, the Securities Administrator, 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 Securities Administrator 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 10% or less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and none of the Master Servicer, the Securities Administrator or the
Trustee assumes 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.



            IN WITNESS WHEREOF, the Securities Administrator has caused this
Certificate to be duly executed.

            NOW, THEREFORE, in consideration of the mutual covenants herein

            Section 1.01 Definitions. All capitalized terms used but not defined

                                   ARTICLE II

                SALE OF MORTGAGE LOANS; PAYMENT OF PURCHASE PRICE

            Section 2.01 Sale of Mortgage Loans. The Seller does hereby agree to
and does hereby sell, assign, set over, and otherwise convey to the Purchaser,
without recourse, on the Closing Date (i) all of its right, title and interest
in and to each Mortgage Loan originated by Option One (the "Option One Mortgage
Loans") and each Mortgage Loan originated by Accredited (the "Accredited
Mortgage Loans") and the related Cut-off Date Principal Balance thereof,
including any Related Documents; (ii) all payments on or collections in respect
of the Mortgage Loans due after the Cut-off Date; (iii) property which secured
such Mortgage Loan and which has been acquired by foreclosure or deed in lieu of
foreclosure; (iv) its interest in any insurance policies in respect of the
Mortgage Loans; (v) the rights of the Seller under the Consulting Agreement and
(vi) all proceeds of any of the foregoing.

            Section 2.02 Obligations of Seller Upon Sale. (a) In connection with
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
other things, for each Mortgage Loan, as of the Cut-off Date, its account number
and Cut-off Date Principal Balance. Such file (the "Mortgage Loan Schedule")
which is set forth as Exhibit D to the Pooling and Servicing Agreement, shall
also be marked as Schedule I to this Agreement and is hereby incorporated into
and made a part of this Agreement.

            In connection with such transfer and assignment of the Mortgage
Loans, the Seller shall, on behalf of the Purchaser, deliver to and deposit with
the Trustee (or the custodians (each, a "Custodian") designated by the Trustee
in the Pooling and Servicing Agreement) the following documents or instruments
(with respect to each Mortgage Loan, a "Mortgage File") with respect to each
Mortgage Loan so transferred and assigned:

            (i) the original Mortgage Note, endorsed in blank or with respect to
any lost Mortgage Note, a 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 the lender's title insurance
policy; and

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

            If any of the documents referred to in Section 2.02(ii), (iii) or
(iv) 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 Seller to deliver such documents shall be deemed to be
satisfied upon (1) delivery to the applicable Custodian on behalf of 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 applicable Custodian on behalf of the Trustee, promptly upon
receipt thereof of either the original or a copy of such document certified by
the applicable public recording office to be a true and complete copy of the
original. If the original lender's title insurance policy was not delivered
pursuant to Section 2.02(v) above, the Seller shall deliver or cause to be
delivered to the applicable Custodian on behalf of the Trustee, a written
commitment or interim binder or preliminary report of title issued by the title
insurance or escrow company, with the original to be delivered to the applicable
Custodian on behalf of the Trustee, promptly upon receipt thereof. The Seller
shall deliver or cause to be delivered to the applicable Custodian on behalf of
the Trustee promptly upon receipt thereof any other original documents
constituting a part of a Mortgage File received with respect to any Mortgage
Loan, including, but not limited to, any original documents evidencing an
assumption or modification of any Mortgage Loan.

            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
applicable Custodian on behalf of the Trustee (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 $1,756,472,164.37 and (ii) deliver to or at the
direction of the Seller on the Closing Date, the Class CE, Class P and Class R
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.

                                   ARTICLE III

               REPRESENTATIONS AND WARRANTIES; REMEDIES FOR BREACH

            Section 3.01 Seller Representations and Warranties Relating to the
Mortgage Loans

            The representations and warranties with respect to the Accredited
Mortgage Loans in the Accredited Sale Agreement were made as of December 21,
2004. The representations and warranties with respect to the Option One Mortgage
Loans in the Option One Sale Agreement were made as of January 27, 2005. 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 Option One AAR and Accredited AAR. 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 an Originator under the related Underlying
Sale Agreement and (ii) a representation or warranty of the Seller under this
Agreement (other than Sections 3.01(k) and 3.01(s) below), the only right or
remedy of the Purchaser shall be the right to enforce the obligations of the
applicable Originator 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 Originators in the Underlying Sale Agreements. 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 Sections 3.01(k) and 3.01(s) below) if the
fact, condition or event constituting such breach also constitutes a breach of a
representation or warranty made by the related Originator in the applicable
Underlying Sale Agreement, without regard to whether such Originator fulfills
its contractual obligations in respect of such representation or warranty. If,
however, Option One fails to reimburse the Trustee for any costs or damages
incurred by the Trust in connection with a breach of its representation set
forth in Section 3.03(i) or 3.03(ddd) of the Option One Sale Agreement or if
Accredited fails to reimburse the Trustee for any costs or damages incurred by
the Trust in connection with a breach of Accredited's representations and
warranties relating to regarding predatory and abusive lending laws set forth in
the Accredited Sale Agreement, or if the Trust incurs any costs or damages as a
result of a breach of the Seller's representation set forth in Section 3.01(s)
below (any such costs or damages, the "Reimbursement Amount"), the Seller shall
pay the Reimbursement Amount to the Trust. The Reimbursement Amount shall be
delivered to the Master Servicer for deposit into the Master Servicer Custodial
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 even 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 related 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 each
Mortgage Loan and the related Mortgage Note and Mortgage and each Mortgage Loan
has not been 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 each 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 each
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) With respect to each Mortgage Loan, 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. With respect to each Mortgage Loan, 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 related Mortgage Loan Schedule;

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

            (p) With respect to each Mortgage Loan, 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. With respect to each Mortgage Loan, 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 applicable Originator and (i) referred to or to otherwise
      considered in the appraisal made for the applicable Originator or (ii)
      which do not adversely affect the appraised value of the Mortgaged
      Property set forth in such appraisal; and

            (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.

            (q) Each 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 applicable Originator, 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 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 applicable Originator, 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 Loans to the Purchaser. No claims have been made under such lender's
title insurance policy, and no prior holder of the Mortgage, including the
applicable Originator 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
applicable Originator or the Seller;

            (r) Any security agreement, chattel mortgage or equivalent document
related to and delivered in connection with each Mortgage Loan establishes and
creates a valid, subsisting and enforceable first lien and first priority
security interest with respect to each first lien Mortgage Loan, on the property
described therein and the applicable Originator has full right to sell and
assign the same to the Purchaser. The Mortgaged Property was not, as of the date
of origination of such 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; and

            (s) No Mortgage Loan (other than a Mortgage Loan that is a New
Jersey covered purchase loan originated on or after November 27, 2003 through
July 6, 2004) is a High Cost Loan or Covered Loan, as applicable (as such terms
are defined in S&P's LEVELS(R) Glossary which is now Version 5.6(b), 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 Master
Servicer, a Custodian, the Securities Administrator 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 Master Servicer, a Custodian, the
Securities Administrator, 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 (or applicable Custodian) 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
as of such date specifically provided herein:

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

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

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

            (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
insolvent by the transfer of the Mortgage Loans, nor is the Seller aware of any
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.

            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

as follows:

            if to the Seller:

            Bank of America, N.A.
            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 Tyron Street
            21st Floor
            Charlotte, North Carolina 28255
            Attention:  Kirk B. Meyers

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
to the enforcement or exercise of any right or remedy against the Seller
pursuant to this Agreement by the Trustee. Such enforcement of a right or remedy
by the Trustee shall have the same force and effect as if the right or remedy
had been enforced or exercised by the Purchaser directly.

            Section 6.09 Survival. The representations and warranties set forth
in Sections 3.01 and 3.02 hereof shall survive the purchase of the Mortgage
Loans hereunder.




            IN WITNESS WHEREOF, the Seller and the Purchaser have caused their
names to be signed to this Mortgage Loan Purchase Agreement by their respective
officers thereunto duly authorized as of the day and year first above written.

                        ) ss.:
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 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, Wells Fargo Bank, N.A., as master servicer and securities
administrator (the "Securities Administrator"), and JPMorgan Chase Bank,
National Association, as 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.)

            5. The Transferee has reviewed the provisions of Section 5.02(d) of
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 Securities Administrator 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
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 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.



            IN WITNESS WHEREOF, the Transferee has caused this instrument to be
executed on its behalf, pursuant to authority of its Board of Directors, by its
duly authorized officer, duly attested, this ___ day of _____________, 20__.

Funding Corporation, JPMorgan Chase Bank, National Association, Wells Fargo
Bank, N.A. as Master Servicer (in such capacity, the "Master Servicer") and the
Securities Administrator (the "PSA"), and Swiss Re Financial Products
Corporation (each a "party" and together "the parties") on the Trade Date
specified below (the "Transaction").

      This letter agreement constitutes a "Confirmation" and the definitions and
provisions contained in the original June 2000 ISDA Definitions (the
"Definitions") as published by the International Swaps and Derivatives
Association, Inc., ("ISDA") are incorporated into this Confirmation. This
Confirmation will be governed by and subject to the terms and conditions which
would be applicable if, prior to the Trade Date, the parties had executed and
delivered an ISDA Master Agreement (Multicurrency-Cross Border), in the form
published by ISDA in 1992 (the "Master Agreement"), with the attached Schedule B
as the Schedule to the Master Agreement and the modifications provided below
(collectively, the "Agreement"). In the event of any inconsistency between the
provisions of the Master Agreement and this Confirmation and the attached
Schedule B, this Confirmation will govern.

as to the terms of the Transaction to which this Confirmation relates. In

      and, in the case of Party B, it is acting as Securities Administrator, and
      in the case of both parties, it has made its own independent decisions to
      enter into that Transaction and as to whether that Transaction is
      appropriate or proper for it based upon its own judgment and upon advice
      from such advisors as it has deemed necessary. It is not relying on any
      communication (written or oral) of the other party as investment advice or
      as a recommendation to enter into that Transaction; it being understood
      that information and explanations related to the terms and conditions of a
      Transaction shall not be considered investment advice or a recommendation
      to enter into that Transaction. No communication (written or oral)
      received from the other party shall be deemed to be an assurance or
      guarantee as to the expected results of that Transaction.

(iii) Evaluation and Understanding. It is capable of evaluating and
      understanding (on its own behalf or through independent professional
      advice), and understands and accepts, the terms, conditions and risks of
      the Agreement and that Transaction. It is also capable of assuming, and
      assumes, the financial and other risks of the Agreement and that
      Transaction.

(iv)  Status of Parties. The other party is not acting as an agent, fiduciary or
      advisor for it in respect of that Transaction.

In this Confirmation "Party A" means Swiss Re Financial Products Corporation and

Servicing Agreement, dated as of March 1, 2005, (the "PSA") among the Securities
Administrator, Asset Backed Funding Corporation and JPMorgan Chase Bank,
National Association.

Part 1. Termination Provisions.

(a)   "Specified Entity" means in relation to Party A for the purpose of the
      Agreement:

      Section 5(a)(v): None.
      Section 5(a)(vi): None.
      Section 5(a)(vii): None.
      Section 5(b)(iv): None.

      Section 5(a)(vi): None.
      Section 5(a)(vii): None.
      Section 5(b)(iv): None.

(b)   "Specified Transaction" will have the meaning specified in Section 14 of
      the Agreement.

(c)   The "Breach of Agreement" provisions of Section 5(a)(ii) of the Agreement
      will be inapplicable to Party A and Party B.

(d)   The "Credit Support Default" provisions of Section 5(a)(iii) of the
      Agreement will be inapplicable to Party B.

(e)   The "Misrepresentation" provisions of Section 5(a)(iv) of the Agreement
      will be inapplicable to Party A and Party B.

      Agreement will be inapplicable to Party A and Party B.

(i)   The "Automatic Early Termination" provision of Section 6(a) of the
      Agreement will be inapplicable to Party A and Party B; provided that where
      there is an Event of Default under Section 5(a)(vii)(1), (3), (4), (5),
      (6) or, to the extent analogous thereto, (8), and the Defaulting Party is
      governed by a system of law that does not permit termination to take place
      after the occurrence of such Event of Default, then the Automatic Early
      Termination provisions of Section 6(a) of the Agreement will apply.

      If an Early Termination Date has occurred under Section 6(a) of the
      Agreement as a result of Automatic Early Termination, and if the
      Non-defaulting Party determines that it has either sustained or incurred a
      loss or damage or benefited from a gain in respect of any Transaction, as
      a result of movement in interest rates, currency exchange rates, other
      relevant rates or market quotations between the Early Termination Date and
      the date upon which the Non-defaulting Party first becomes aware that such
      Event of Default has occurred under Section 6(a), then (i) the amount of
      such loss or damage shall be added to the amount due by the Defaulting
      Party or deducted from the amount due by the Non-defaulting Party, as the
      case may be (in both cases pursuant to Section 6(e)(i)(3) of the
      Agreement); or (ii) the amount of such gain shall be deducted from the
      amount due by the Defaulting Party or added to the amount due by the
      Non-defaulting Party, as the case may be (in both cases pursuant to
      Section 6(e)(i)(3) of the Agreement).

(j)   Payments on Early Termination. For the purpose of Section 6(e) of the
      Agreement:

      (i) Market Quotation will apply; and
      (ii) The Second Method will apply.

(k)   "Termination Currency" means United States Dollars.

(l)   "Additional Termination Event" will not apply, except as provided in Part
      5(m) or in any confirmation.

      under Section 4(a)(iii) of the Agreement by reason of material prejudice
      to its legal or commercial position.

      Payee Representations. For the purpose of Section 3(f) of this Agreement,
      Party A and Party B make the following representations:

      recently published rules regarding asset-backed securities (Release Nos.
      33-8518, 34-50905; File No. 57-21-0433-8419), applicable to this

      If a Ratings Event (as defined below) occurs with respect to Party A (or

      expense, (i) assign this Transaction hereunder to a third party
      satisfactory to the Securities Administrator within (30) days of such
      Ratings Event that meets or exceeds, or as to which any applicable credit
      support provider meets or exceeds, the Approved Ratings Thresholds (as
      defined below) on terms substantially similar to this Confirmation or (ii)
      deliver collateral, in an amount equal to the Exposure (as defined below),
      and an executed ISDA Credit Support Annex satisfactory to the Securities
      Administrator within (30) days of such Ratings Event and subject to
      Moody's, Fitch's and S&P's written confirmation that delivery of such
      collateral in the context of such downgrade will not result in a
      withdrawal, qualification or downgrade of the then current ratings
      assigned to the Securities. For avoidance of doubt, a downgrade of the
      rating on the Securities could occur in the event that Party A does not
      post sufficient collateral. For purposes of this Transaction, a "Ratings
      Event" shall occur with respect to Party A (or any applicable credit
      support provider), if its short-term unsecured and unsubordinated debt
      ceases to be rated at least "A-1" by S&P and at least "P-1" by Moody's
      (including in connection with a merger, consolidation or other similar
      transaction by Party A or any applicable credit support provider) such
      ratings being referred to herein as the "Approved Ratings Thresholds,"
      (unless, within 30 days thereafter, each of Moody's, Fitch and S&P has
      reconfirmed the ratings of the Securities, as applicable, which was in
      effect immediately prior thereto). Only with respect to such Ratings
      Event, "Exposure" shall mean the greater of the following: (i) the
      mark-to-market value of the Transaction as of the Valuation Date (as such
      term is defined in the ISDA Credit Support Annex); (ii) the amount of the
      next payment due under the Transaction and (iii) one percent of the
      Notional Amount for the respective Calculation Period.

(n)   Additional Termination Event

      Additional Termination Event will apply if a Ratings Event has occurred
      and Party A has not complied with (m) above, then an Additional
      Termination Event shall have occurred with respect to Party A and Party A
      shall be the sole Affected Party with respect to such Additional
      Termination Event.




                                                                       Exhibit A

to the Chief Financial Officer of the Guarantor. This Guarantee is not however
dependent in any way on the manner of the demand for payment. Delay in making a
claim will not affect the Guarantor's obligations under this Guarantee unless
the relevant legal limitation period has expired.

3. This Guarantee constitutes, and is intended by the Guarantor to constitute,
an unlimited non-accessory undertaking ("unbeschrankte, nicht akzessorische
Verpflichtung") within the meaning of Article 111 of the Swiss Code of
Obligations (`CO`) and is not a mere surety ("Burgschaft") within the meaning of
Article 492 et seq of the CO.

4. Notwithstanding any reference to the obligations of THE GUARANTEED
SUBSIDIARY, the Guarantor's obligations under this Guarantee are its absolute
and independent obligations as a primary obligor. Payment of a claim hereunder
is required as soon as the Guaranteed Obligations are due and payable.

5. To the extent that any event or circumstance would give rise to any legal or
equitable discharge, defence or other rights of the Guarantor under this
Guarantee, but which event or circumstance would not give rise to any discharge,
defence or other rights of THE GUARANTEED SUBSIDIARY under the Agreements, the
Guarantor hereby fully waives, subject to paragraph 7 below, such discharge,
defence, or other rights and the Guarantor's liability hereunder shall continue
as if such event or circumstance had not arisen.

6. The Guarantor further agrees, subject to paragraph 7 below, that to the
extent that any event or circumstance gives rise to any legal or equitable
discharge, defence or other rights available to both the Guarantor under the
Guarantee and THE GUARANTEED SUBSIDIARY under the Agreements, the Guarantor
hereby agrees to waive such discharge, defense or other rights against the
Beneficiary, until such time as all the Guaranteed Obligations in relation to
the same event or circumstance have been fully met as required to protect
investors in the Rated Securities.

7. Notwithstanding any other provision of this Guarantee, the Guarantor will
have the right, prior to making any payment under this Guarantee, to (a) assert
such rights of offset as are set forth in the Agreements to the extent that such
rights relate to amounts due and payable by the Beneficiary to THE GUARANTEED
SUBSIDIARY and not to amounts which are subject to dispute; and (b) defend
manifestly fraudulent claims under this Guarantee made by the Beneficiary.

8. This Guarantee will continue in full force and effect in relation to all
Guaranteed Obligations until all the Guaranteed Obligations have been satisfied
in full. For the avoidance of doubt, all Guaranteed Obligations entered into by
THE GUARANTEED SUBSIDIARY during the term of this Guarantee shall be honoured in
accordance with this Guarantee and shall be binding on the Guarantor and its
successors and assigns. This Guarantee may be amended only as necessary to
reflect changes to the Guaranteed Obligations which are validly agreed to by the
Beneficiary (or the trustee as assignee of the Beneficiary) in accordance with
the terms of the Rated Securities, including any requirement to obtain the
consent of some or all of the investors in the Rated Securities.

9. If any payment by THE GUARANTEED SUBSIDIARY is avoided, recaptured or reduced
as a result of insolvency or any similar event affecting creditors rights
generally having occurred in respect of THE GUARANTEED SUBSIDIARY, the
Guarantor`s liability under this Guarantee shall continue as if the avoided,
recaptured or reduced payment had not occurred.

10. Upon payment by the Guarantor to the Beneficiary of any amount due under
this Guarantee, the Guarantor shall be entitled to require the assignment to it
of the rights of the Beneficiary against THE GUARANTEED SUBSIDIARY to the extent
satisfied by such payment, and the Beneficiary will take at the Guarantor's
expense such steps as the Guarantor may reasonably require to implement such
assignment. The Guarantor shall not exercise any rights against THE GUARANTEED
SUBSIDIARY which it may acquire in consequence of such payment and assignment
unless and until all the Guaranteed Obligations to the Beneficiary shall have
been paid in full.

11. This Guarantee is governed and will be construed in accordance with Swiss
law. The exclusive place of jurisdiction for any legal proceeding hereunder
shall be Zurich, Switzerland.


IN WITNESS WHEREOF, the Guarantor has caused this Guarantee to be executed in
its name as of the 30th day of March, 2005.

Dear Sir/Madam:

Pooling and Servicing Agreement, dated as of March 1, 2005, among Asset Backed
Funding Corporation, JPMorgan Chase Bank, National Association, Wells Fargo
Bank, N.A. as Master Servicer (in such capacity, the "Master Servicer") and the
Securities Administrator (the "PSA"), and Swiss Re Financial Products
Corporation (each a "party" and together "the parties") on the Trade Date
specified below (the "Transaction").

      This letter agreement constitutes a "Confirmation" and the definitions and
provisions contained in the original June 2000 ISDA Definitions (the
"Definitions") as published by the International Swaps and Derivatives
Association, Inc., ("ISDA") are incorporated into this Confirmation. This
Confirmation will be governed by and subject to the terms and conditions which
would be applicable if, prior to the Trade Date, the parties had executed and
delivered an ISDA Master Agreement (Multicurrency-Cross Border), in the form
published by ISDA in 1992 (the "Master Agreement"), with the attached Schedule B
as the Schedule to the Master Agreement and the modifications provided below
(collectively, the "Agreement"). In the event of any inconsistency between the
provisions of the Master Agreement and this Confirmation and the attached
Schedule B, this Confirmation will govern.

1. This Confirmation evidences a complete binding agreement between the parties
as to the terms of the Transaction to which this Confirmation relates. In
addition, each party represents to the other party and will be deemed to

      and, in the case of Party B, it is acting as Securities Administrator, and
      in the case of both parties, it has made its own independent decisions to
      enter into that Transaction and as to whether that Transaction is
      appropriate or proper for it based upon its own judgment and upon advice
      from such advisors as it has deemed necessary. It is not relying on any
      communication (written or oral) of the other party as investment advice or
      as a recommendation to enter into that Transaction; it being understood
      that information and explanations related to the terms and conditions of a
      Transaction shall not be considered investment advice or a recommendation
      to enter into that Transaction. No communication (written or oral)
      received from the other party shall be deemed to be an assurance or
      guarantee as to the expected results of that Transaction.

(iii) Evaluation and Understanding. It is capable of evaluating and
      understanding (on its own behalf or through independent professional
      advice), and understands and accepts, the terms, conditions and risks of
      the Agreement and that Transaction. It is also capable of assuming, and
      assumes, the financial and other risks of the Agreement and that
      Transaction.

(iv)  Status of Parties. The other party is not acting as an agent, fiduciary or
      advisor for it in respect of that Transaction.

Securities Administrator of the ABFC 2005-HE1 Trust.

      Agreement:

      Section 5(a)(v): None.
      Section 5(a)(vi): None.
      Section 5(a)(vii): None.

      Section 5(a)(vii): None.
      Section 5(b)(iv): None.

      will be inapplicable to Party A and Party B.

(d)   The "Credit Support Default" provisions of Section 5(a)(iii) of the
      Agreement will be inapplicable to Party B.

      there is an Event of Default under Section 5(a)(vii)(1), (3), (4), (5),

      loss or damage or benefited from a gain in respect of any Transaction, as

      relevant rates or market quotations between the Early Termination Date and
      the date upon which the Non-defaulting Party first becomes aware that such
      Event of Default has occurred under Section 6(a), then (i) the amount of
      such loss or damage shall be added to the amount due by the Defaulting
      Party or deducted from the amount due by the Non-defaulting Party, as the
      case may be (in both cases pursuant to Section 6(e)(i)(3) of the
      Agreement); or (ii) the amount of such gain shall be deducted from the
      amount due by the Defaulting Party or added to the amount due by the
      Non-defaulting Party, as the case may be (in both cases pursuant to
      Section 6(e)(i)(3) of the Agreement).

(j)   Payments on Early Termination. For the purpose of Section 6(e) of the
      Agreement:

      (i) Market Quotation will apply; and
      (ii) The Second Method will apply.

      under Section 4(a)(iii) of the Agreement by reason of material prejudice
      to its legal or commercial position.

(i)   Set-off.

      The provisions for Set-off set forth in Section 6(e) of the Agreement
      shall not apply for purposes of this Transaction.

(j)   Amendment to ISDA Form.

      The "Failure to Pay or Deliver" provision in Section 5(a)(i) of the
      Agreement is hereby amended by deleting the word "third" in the third line
      thereof and inserting the word "first" in place thereof.

(k)   Section 1(c)

      For purposes of Section 1(c) of the Agreement, this Transaction shall be
      the sole Transaction under the Agreement.

(l)   Cooperation

      Party A hereby agrees to use commercially reasonable efforts to cooperate
      with Asset Backed Funding Corporation to enable Asset Backed Funding
      Cooperation to timely comply with the Securities and Exchange Commission's
      proposed rules regarding asset-backed securities (Release Nos. 33-8518,
      34-50905; File No. 57-21-0433-8419), applicable to this Transaction. Asset
      Backed Funding Corporation is an intended third party beneficiary with
      respect to this provision and shall be entitled to enforce Party A's
      obligations hereunder.

(m)   Rating Agency Downgrade

      If a Ratings Event (as defined below) occurs with respect to Party A (or
      any applicable credit support provider), then Party A shall at its own
      expense, (i) assign this Transaction hereunder to a third party
      satisfactory to the Securities Administrator within (30) days of such
      Ratings Event that meets or exceeds, or as to which any applicable credit
      support provider meets or exceeds, the Approved Ratings Thresholds (as
      defined below) on terms substantially similar to this Confirmation or (ii)
      deliver collateral, in an amount equal to the Exposure (as defined below),
      and an executed ISDA Credit Support Annex satisfactory to the Securities
      Administrator within (30) days of such Ratings Event and subject to
      Moody's, Fitch's and S&P's written confirmation that delivery of such
      collateral in the context of such downgrade will not result in a
      withdrawal, qualification or downgrade of the then current ratings
      assigned to the Securities. For avoidance of doubt, a downgrade of the
      rating on the Securities could occur in the event that Party A does not
      post sufficient collateral. For purposes of this Transaction, a "Ratings
      Event" shall occur with respect to Party A (or any applicable credit
      support provider), if its short-term unsecured and unsubordinated debt
      ceases to be rated at least "A-1" by S&P and at least "P-1" by Moody's
      (including in connection with a merger, consolidation or other similar
      transaction by Party A or any applicable credit support provider) such
      ratings being referred to herein as the "Approved Ratings Thresholds,"
      (unless, within 30 days thereafter, each of Moody's, Fitch and S&P has
      reconfirmed the ratings of the Securities, as applicable, which was in
      effect immediately prior thereto). Only with respect to such Ratings
      Event, "Exposure" shall mean the greater of the following: (i) the
      mark-to-market value of the Transaction as of the Valuation Date (as such
      term is defined in the ISDA Credit Support Annex); (ii) the amount of the
      next payment due under the Transaction and (iii) one percent of the
      Notional Amount for the respective Calculation Period.

(n)   Additional Termination Event

      Additional Termination Event will apply if a Ratings Event has occurred
      and Party A has not complied with (m) above, then an Additional
      Termination Event shall have occurred with respect to Party A and Party A
      shall be the sole Affected Party with respect to such Additional
      Termination Event.



                                                                       Exhibit A

                                    GUARANTY

To: Wells Fargo Bank, N.A.,, (the "Beneficiary"), not individually, but solely
as Securities Administrator of the ABFC 2005-HE1 Trust - Class A-2SS and Class
A-2MZ Certificates (the "Rated Security")

1. The undersigned, SWISS REINSURANCE COMPANY, a Swiss company (the
"Guarantor"), hereby absolutely and unconditionally guarantees the prompt
payment as and when due of all obligations of its indirect, wholly-owned
subsidiary SWISS RE FINANCIAL PRODUCTS CORPORATION, a Delaware corporation ("THE
GUARANTEED SUBSIDIARY") under, in connection with or ancillary to a long form
confirmation dated as of March 30, 2005 between the Beneficiary and THE
GUARANTEED SUBSIDIARY as amended or restated from time to time (the
"Agreements") which support the issuance of the Rated Security. In this
Guarantee these obligations are referred to as the "Guaranteed Obligations".
This Guarantee is given solely for the benefit of, and is enforceable only by,
the Beneficiary or any trustee as assignee of the Beneficiary to which this
Guarantee has been validly assigned in accordance with applicable law and who is
acting as trustee for the investors in the Rated Securities.

2. This Guarantee constitutes a Guarantee of payment and not of collection and
is not conditional or contingent upon any attempts to collect from, or pursue or
exhaust any rights or remedies against, THE GUARANTEED SUBSIDIARY. A demand for
payment hereunder may at the Beneficiary's option be made in writing addressed
to the Chief Financial Officer of the Guarantor. This Guarantee is not however
dependent in any way on the manner of the demand for payment. Delay in making a
claim will not affect the Guarantor's obligations under this Guarantee unless
the relevant legal limitation period has expired.

3. This Guarantee constitutes, and is intended by the Guarantor to constitute,
an unlimited non-accessory undertaking ("unbeschrankte, nicht akzessorische
Verpflichtung") within the meaning of Article 111 of the Swiss Code of
Obligations (`CO`) and is not a mere surety ("Burgschaft") within the meaning of
Article 492 et seq of the CO.

4. Notwithstanding any reference to the obligations of THE GUARANTEED
SUBSIDIARY, the Guarantor's obligations under this Guarantee are its absolute
and independent obligations as a primary obligor. Payment of a claim hereunder
is required as soon as the Guaranteed Obligations are due and payable.

5. To the extent that any event or circumstance would give rise to any legal or
equitable discharge, defence or other rights of the Guarantor under this
Guarantee, but which event or circumstance would not give rise to any discharge,
defence or other rights of THE GUARANTEED SUBSIDIARY under the Agreements, the
Guarantor hereby fully waives, subject to paragraph 7 below, such discharge,
defence, or other rights and the Guarantor's liability hereunder shall continue
as if such event or circumstance had not arisen.

6. The Guarantor further agrees, subject to paragraph 7 below, that to the
extent that any event or circumstance gives rise to any legal or equitable
discharge, defence or other rights available to both the Guarantor under the
Guarantee and THE GUARANTEED SUBSIDIARY under the Agreements, the Guarantor
hereby agrees to waive such discharge, defense or other rights against the
Beneficiary, until such time as all the Guaranteed Obligations in relation to
the same event or circumstance have been fully met as required to protect
investors in the Rated Securities.

7. Notwithstanding any other provision of this Guarantee, the Guarantor will
have the right, prior to making any payment under this Guarantee, to (a) assert
such rights of offset as are set forth in the Agreements to the extent that such
rights relate to amounts due and payable by the Beneficiary to THE GUARANTEED
SUBSIDIARY and not to amounts which are subject to dispute; and (b) defend
manifestly fraudulent claims under this Guarantee made by the Beneficiary.

8. This Guarantee will continue in full force and effect in relation to all
Guaranteed Obligations until all the Guaranteed Obligations have been satisfied
in full. For the avoidance of doubt, all Guaranteed Obligations entered into by
THE GUARANTEED SUBSIDIARY during the term of this Guarantee shall be honoured in
accordance with this Guarantee and shall be binding on the Guarantor and its
successors and assigns. This Guarantee may be amended only as necessary to
reflect changes to the Guaranteed Obligations which are validly agreed to by the
Beneficiary (or the trustee as assignee of the Beneficiary) in accordance with
the terms of the Rated Securities, including any requirement to obtain the
consent of some or all of the investors in the Rated Securities.

9. If any payment by THE GUARANTEED SUBSIDIARY is avoided, recaptured or reduced
as a result of insolvency or any similar event affecting creditors rights
generally having occurred in respect of THE GUARANTEED SUBSIDIARY, the
Guarantor`s liability under this Guarantee shall continue as if the avoided,
recaptured or reduced payment had not occurred.

10. Upon payment by the Guarantor to the Beneficiary of any amount due under
this Guarantee, the Guarantor shall be entitled to require the assignment to it
of the rights of the Beneficiary against THE GUARANTEED SUBSIDIARY to the extent
satisfied by such payment, and the Beneficiary will take at the Guarantor's
expense such steps as the Guarantor may reasonably require to implement such
assignment. The Guarantor shall not exercise any rights against THE GUARANTEED
SUBSIDIARY which it may acquire in consequence of such payment and assignment
unless and until all the Guaranteed Obligations to the Beneficiary shall have
been paid in full.

11. This Guarantee is governed and will be construed in accordance with Swiss
law. The exclusive place of jurisdiction for any legal proceeding hereunder
shall be Zurich, Switzerland.

IN WITNESS WHEREOF, the Guarantor has caused this Guarantee to be executed in
its name as of the 30th day of March, 2005.

Dear Sir/Madam:

         The purpose of this letter agreement is to confirm the terms and
conditions of the Transaction entered into between Wells Fargo Bank, N.A., as
Securities Administrator (the "Securities Administrator") pursuant to the
Pooling and Servicing Agreement, dated as of March 1, 2005, among Asset Backed
Funding Corporation, JPMorgan Chase Bank, National Association, Wells Fargo
Bank, N.A. as Master Servicer (in such capacity, the "Master Servicer") and the
Securities Administrator (the "PSA"), and Swiss Re Financial Products
Corporation (each a "party" and together "the parties") on the Trade Date
specified below (the "Transaction").

         This letter agreement constitutes a "Confirmation" and the definitions
and provisions contained in the original June 2000 ISDA Definitions (the
"Definitions") as published by the International Swaps and Derivatives
Association, Inc., ("ISDA") are incorporated into this Confirmation. This
Confirmation will be governed by and subject to the terms and conditions which
would be applicable if, prior to the Trade Date, the parties had executed and
delivered an ISDA Master Agreement (Multicurrency-Cross Border), in the form
published by ISDA in 1992 (the "Master Agreement"), with the attached Schedule B
as the Schedule to the Master Agreement and the modifications provided below
(collectively, the "Agreement"). In the event of any inconsistency between the
provisions of the Master Agreement and this Confirmation and the attached
Schedule B, this Confirmation will govern.

1. This Confirmation evidences a complete binding agreement between the parties
as to the terms of the Transaction to which this Confirmation relates. In
addition, each party represents to the other party and will be deemed to
represent to the other party on the date on which it enters into a Transaction

      agent when entering into the Transaction and in the case of Party B, it is

      and, in the case of Party B, it is acting as Securities Administrator, and
      in the case of both parties, it has made its own independent decisions to
      enter into that Transaction and as to whether that Transaction is
      appropriate or proper for it based upon its own judgment and upon advice
      from such advisors as it has deemed necessary. It is not relying on any
      communication (written or oral) of the other party as investment advice or
      as a recommendation to enter into that Transaction; it being understood
      that information and explanations related to the terms and conditions of a
      Transaction shall not be considered investment advice or a recommendation
      to enter into that Transaction. No communication (written or oral)
      received from the other party shall be deemed to be an assurance or
      guarantee as to the expected results of that Transaction.

(iii) Evaluation and Understanding. It is capable of evaluating and
      understanding (on its own behalf or through independent professional
      advice), and understands and accepts, the terms, conditions and risks of
      the Agreement and that Transaction. It is also capable of assuming, and
      assumes, the financial and other risks of the Agreement and that
      Transaction.

(iv)  Status of Parties. The other party is not acting as an agent, fiduciary or
      advisor for it in respect of that Transaction.

In this Confirmation "Party A" means Swiss Re Financial Products Corporation and
"Party B" means Wells Fargo Bank, N.A., not individually, but solely as
Securities Administrator of the ABFC 2005-HE1 Trust.

SCHEDULE B to the Confirmation dated as of March 30, 2005
Re: Reference Number 560135-560136

Between Swiss Re Financial Products Corporation ("Party A") and Wells Fargo
Bank, N.A., as Securities Administrator ("Party B"), pursuant to the Pooling and
Servicing Agreement, dated as of March 1, 2005, (the "PSA") among the Securities
Administrator, Asset Backed Funding Corporation and JPMorgan Chase Bank,
National Association.

Part 1. Termination Provisions.

(a)   "Specified Entity" means in relation to Party A for the purpose of the
      Agreement:

      Section 5(a)(v): None.
      Section 5(a)(vi): None.
      Section 5(a)(vii): None.
      Section 5(b)(iv): None.

      and in relation to Party B for the purpose of the Agreement:

      Section 5(a)(v): None.
      Section 5(a)(vi): None.
      Section 5(a)(vii): None.
      Section 5(b)(iv): None.

(b)   "Specified Transaction" will have the meaning specified in Section 14 of
      the Agreement.

(c)   The "Breach of Agreement" provisions of Section 5(a)(ii) of the Agreement
      will be inapplicable to Party A and Party B.

(d)   The "Credit Support Default" provisions of Section 5(a)(iii) of the
      Agreement will be inapplicable to Party B.

(e)   The "Misrepresentation" provisions of Section 5(a)(iv) of the Agreement
      will be inapplicable to Party A and Party B.

(f)   The "Default Under Specified Transaction" provisions of Section 5(a)(v) of
      the Agreement will be inapplicable to Party A and Party B.

(g)   The "Cross Default" provisions of Section 5(a)(vi) of the Agreement will
      be inapplicable to Party A and Party B

(h)   The "Credit Event Upon Merger" provisions of Section 5(b)(iv) of the
      Agreement will be inapplicable to Party A and Party B.

(i)   The "Automatic Early Termination" provision of Section 6(a) of the
      Agreement will be inapplicable to Party A and Party B; provided that where
      there is an Event of Default under Section 5(a)(vii)(1), (3), (4), (5),
      (6) or, to the extent analogous thereto, (8), and the Defaulting Party is
      governed by a system of law that does not permit termination to take place
      after the occurrence of such Event of Default, then the Automatic Early
      Termination provisions of Section 6(a) of the Agreement will apply.

      If an Early Termination Date has occurred under Section 6(a) of the
      Agreement as a result of Automatic Early Termination, and if the
      Non-defaulting Party determines that it has either sustained or incurred a
      loss or damage or benefited from a gain in respect of any Transaction, as
      a result of movement in interest rates, currency exchange rates, other
      relevant rates or market quotations between the Early Termination Date and
      the date upon which the Non-defaulting Party first becomes aware that such
      Event of Default has occurred under Section 6(a), then (i) the amount of
      such loss or damage shall be added to the amount due by the Defaulting
      Party or deducted from the amount due by the Non-defaulting Party, as the
      case may be (in both cases pursuant to Section 6(e)(i)(3) of the
      Agreement); or (ii) the amount of such gain shall be deducted from the
      amount due by the Defaulting Party or added to the amount due by the
      Non-defaulting Party, as the case may be (in both cases pursuant to
      Section 6(e)(i)(3) of the Agreement).

(j)   Payments on Early Termination. For the purpose of Section 6(e) of the
      Agreement:

      (i) Market Quotation will apply; and
      (ii) The Second Method will apply.

(k)   "Termination Currency" means United States Dollars.

(l)   "Additional Termination Event" will not apply, except as provided in Part
      5(m) or in any confirmation.

      Payer Representations. For the purpose of Section 3(e) of the Agreement,
      Party A will make the following representation and Party B will not make

      the other party contained in Section 4(d) of the Agreement, provided that
      it shall not be a breach of this representation where reliance is placed
      on clause (ii) and the other party does not deliver a form or document
      under Section 4(a)(iii) of the Agreement by reason of material prejudice
      to its legal or commercial position.

      Payee Representations. For the purpose of Section 3(f) of this Agreement,
      Party A and Party B make the following representations:

      (i)   Party A represents that it is a corporation organized under the laws

      proposed rules regarding asset-backed securities (Release Nos. 33-8518,
      34-50905; File No. 57-21-0433-8419), applicable to this Transaction. Asset
      Backed Funding Corporation is an intended third party beneficiary with

(m)   Rating Agency Downgrade

      If a Ratings Event (as defined below) occurs with respect to Party A (or

      expense, (i) assign this Transaction hereunder to a third party
      satisfactory to the Securities Administrator within (30) days of such
      Ratings Event that meets or exceeds, or as to which any applicable credit
      support provider meets or exceeds, the Approved Ratings Thresholds (as
      defined below) on terms substantially similar to this Confirmation or (ii)
      deliver collateral, in an amount equal to the Exposure (as defined below),
      and an executed ISDA Credit Support Annex satisfactory to the Securities
      Administrator within (30) days of such Ratings Event and subject to
      Moody's, Fitch's and S&P's written confirmation that delivery of such
      collateral in the context of such downgrade will not result in a
      withdrawal, qualification or downgrade of the then current ratings
      assigned to the Securities. For avoidance of doubt, a downgrade of the
      rating on the Securities could occur in the event that Party A does not
      post sufficient collateral. For purposes of this Transaction, a "Ratings
      Event" shall occur with respect to Party A (or any applicable credit
      support provider), if its short-term unsecured and unsubordinated debt
      ceases to be rated at least "A-1" by S&P and at least "P-1" by Moody's
      (including in connection with a merger, consolidation or other similar
      transaction by Party A or any applicable credit support provider) such
      ratings being referred to herein as the "Approved Ratings Thresholds,"
      (unless, within 30 days thereafter, each of Moody's, Fitch and S&P has
      reconfirmed the ratings of the Securities, as applicable, which was in
      effect immediately prior thereto). Only with respect to such Ratings
      Event, "Exposure" shall mean the greater of the following: (i) the
      mark-to-market value of the Transaction as of the Valuation Date (as such
      term is defined in the ISDA Credit Support Annex); (ii) the amount of the
      next payment due under the Transaction and (iii) one percent of the
      Notional Amount for the respective Calculation Period.

(n)   Additional Termination Event

      Additional Termination Event will apply if a Ratings Event has occurred
      and Party A has not complied with (m) above, then an Additional
      Termination Event shall have occurred with respect to Party A and Party A
      shall be the sole Affected Party with respect to such Additional
      Termination Event.



                                                                       Exhibit A

                                    GUARANTY

To: Wells Fargo Bank, N.A.,, (the "Beneficiary"), not individually, but solely
as Securities Administrator of the ABFC 2005-HE1 Trust - Class A-3A, Class A-3B,
and Class A-3C Certificates (the "Rated Security")

1. The undersigned, SWISS REINSURANCE COMPANY, a Swiss company (the
"Guarantor"), hereby absolutely and unconditionally guarantees the prompt
payment as and when due of all obligations of its indirect, wholly-owned
subsidiary SWISS RE FINANCIAL PRODUCTS CORPORATION, a Delaware corporation ("THE
GUARANTEED SUBSIDIARY") under, in connection with or ancillary to a long form
confirmation dated as of March 30, 2005 between the Beneficiary and THE
GUARANTEED SUBSIDIARY as amended or restated from time to time (the
"Agreements") which support the issuance of the Rated Security. In this
Guarantee these obligations are referred to as the "Guaranteed Obligations".
This Guarantee is given solely for the benefit of, and is enforceable only by,
the Beneficiary or any trustee as assignee of the Beneficiary to which this
Guarantee has been validly assigned in accordance with applicable law and who is
acting as trustee for the investors in the Rated Securities.

2. This Guarantee constitutes a Guarantee of payment and not of collection and
is not conditional or contingent upon any attempts to collect from, or pursue or
exhaust any rights or remedies against, THE GUARANTEED SUBSIDIARY. A demand for
payment hereunder may at the Beneficiary's option be made in writing addressed
to the Chief Financial Officer of the Guarantor. This Guarantee is not however
dependent in any way on the manner of the demand for payment. Delay in making a
claim will not affect the Guarantor's obligations under this Guarantee unless
the relevant legal limitation period has expired.

3. This Guarantee constitutes, and is intended by the Guarantor to constitute,
an unlimited non-accessory undertaking ("unbeschrankte, nicht akzessorische
Verpflichtung") within the meaning of Article 111 of the Swiss Code of
Obligations (`CO`) and is not a mere surety ("Burgschaft") within the meaning of
Article 492 et seq of the CO.

4. Notwithstanding any reference to the obligations of THE GUARANTEED
SUBSIDIARY, the Guarantor's obligations under this Guarantee are its absolute
and independent obligations as a primary obligor. Payment of a claim hereunder
is required as soon as the Guaranteed Obligations are due and payable.

5. To the extent that any event or circumstance would give rise to any legal or
equitable discharge, defence or other rights of the Guarantor under this
Guarantee, but which event or circumstance would not give rise to any discharge,
defence or other rights of THE GUARANTEED SUBSIDIARY under the Agreements, the
Guarantor hereby fully waives, subject to paragraph 7 below, such discharge,
defence, or other rights and the Guarantor's liability hereunder shall continue
as if such event or circumstance had not arisen.

6. The Guarantor further agrees, subject to paragraph 7 below, that to the
extent that any event or circumstance gives rise to any legal or equitable
discharge, defence or other rights available to both the Guarantor under the
Guarantee and THE GUARANTEED SUBSIDIARY under the Agreements, the Guarantor
hereby agrees to waive such discharge, defense or other rights against the
Beneficiary, until such time as all the Guaranteed Obligations in relation to
the same event or circumstance have been fully met as required to protect
investors in the Rated Securities.

7. Notwithstanding any other provision of this Guarantee, the Guarantor will
have the right, prior to making any payment under this Guarantee, to (a) assert
such rights of offset as are set forth in the Agreements to the extent that such
rights relate to amounts due and payable by the Beneficiary to THE GUARANTEED
SUBSIDIARY and not to amounts which are subject to dispute; and (b) defend
manifestly fraudulent claims under this Guarantee made by the Beneficiary.

8. This Guarantee will continue in full force and effect in relation to all
Guaranteed Obligations until all the Guaranteed Obligations have been satisfied
in full. For the avoidance of doubt, all Guaranteed Obligations entered into by
THE GUARANTEED SUBSIDIARY during the term of this Guarantee shall be honoured in
accordance with this Guarantee and shall be binding on the Guarantor and its
successors and assigns. This Guarantee may be amended only as necessary to
reflect changes to the Guaranteed Obligations which are validly agreed to by the
Beneficiary (or the trustee as assignee of the Beneficiary) in accordance with
the terms of the Rated Securities, including any requirement to obtain the
consent of some or all of the investors in the Rated Securities.

9. If any payment by THE GUARANTEED SUBSIDIARY is avoided, recaptured or reduced
as a result of insolvency or any similar event affecting creditors rights
generally having occurred in respect of THE GUARANTEED SUBSIDIARY, the
Guarantor`s liability under this Guarantee shall continue as if the avoided,
recaptured or reduced payment had not occurred.

10. Upon payment by the Guarantor to the Beneficiary of any amount due under
this Guarantee, the Guarantor shall be entitled to require the assignment to it
of the rights of the Beneficiary against THE GUARANTEED SUBSIDIARY to the extent
satisfied by such payment, and the Beneficiary will take at the Guarantor's
expense such steps as the Guarantor may reasonably require to implement such
assignment. The Guarantor shall not exercise any rights against THE GUARANTEED
SUBSIDIARY which it may acquire in consequence of such payment and assignment
unless and until all the Guaranteed Obligations to the Beneficiary shall have
been paid in full.

11. This Guarantee is governed and will be construed in accordance with Swiss
law. The exclusive place of jurisdiction for any legal proceeding hereunder
shall be Zurich, Switzerland.

IN WITNESS WHEREOF, the Guarantor has caused this Guarantee to be executed in
its name as of the 30th day of March, 2005.

Dear Sir/Madam:

Funding Corporation, JPMorgan Chase Bank, National Association, Wells Fargo
Bank, N.A. as Master Servicer (in such capacity, the "Master Servicer") and the
Securities Administrator (the "PSA"), and Swiss Re Financial Products
Corporation (each a "party" and together "the parties") on the Trade Date
specified below (the "Transaction").

      This letter agreement constitutes a "Confirmation" and the definitions and
provisions contained in the original June 2000 ISDA Definitions (the

Confirmation will be governed by and subject to the terms and conditions which
would be applicable if, prior to the Trade Date, the parties had executed and
delivered an ISDA Master Agreement (Multicurrency-Cross Border), in the form
published by ISDA in 1992 (the "Master Agreement"), with the attached Schedule B
as the Schedule to the Master Agreement and the modifications provided below
(collectively, the "Agreement"). In the event of any inconsistency between the
provisions of the Master Agreement and this Confirmation and the attached
Schedule B, this Confirmation will govern.

1. This Confirmation evidences a complete binding agreement between the parties
as to the terms of the Transaction to which this Confirmation relates. In
addition, each party represents to the other party and will be deemed to

      and, in the case of Party B, it is acting as Securities Administrator, and
      in the case of both parties, it has made its own independent decisions to
      enter into that Transaction and as to whether that Transaction is
      appropriate or proper for it based upon its own judgment and upon advice
      from such advisors as it has deemed necessary. It is not relying on any
      communication (written or oral) of the other party as investment advice or
      as a recommendation to enter into that Transaction; it being understood
      that information and explanations related to the terms and conditions of a
      Transaction shall not be considered investment advice or a recommendation
      to enter into that Transaction. No communication (written or oral)
      received from the other party shall be deemed to be an assurance or
      guarantee as to the expected results of that Transaction.

(iii) Evaluation and Understanding. It is capable of evaluating and
      understanding (on its own behalf or through independent professional
      advice), and understands and accepts, the terms, conditions and risks of
      the Agreement and that Transaction. It is also capable of assuming, and
      assumes, the financial and other risks of the Agreement and that
      Transaction.

(iv)  Status of Parties. The other party is not acting as an agent, fiduciary or
      advisor for it in respect of that Transaction.

In this Confirmation "Party A" means Swiss Re Financial Products Corporation and
"Party B" means Wells Fargo Bank, N.A., not individually, but solely as
Securities Administrator of the ABFC 2005-HE1 Trust.

SCHEDULE B to the Confirmation dated as of March 30, 2005
Re: Reference Number 560140/560141

Between Swiss Re Financial Products Corporation ("Party A") and Wells Fargo
Bank, N.A., as Securities Administrator ("Party B"), pursuant to the Pooling and
Servicing Agreement, dated as of March 1, 2005, (the "PSA") among the Securities
Administrator, the Master Servicer, Asset Backed Funding Corporation and
JPMorgan Chase Bank, National Association.

Part 1. Termination Provisions.

(a)   "Specified Entity" means in relation to Party A for the purpose of the
      Agreement:

      Section 5(a)(v): None.
      Section 5(a)(vi): None.
      Section 5(a)(vii): None.
      Section 5(b)(iv): None.

      and in relation to Party B for the purpose of the Agreement:

      Section 5(a)(v): None.
      Section 5(a)(vi): None.
      Section 5(a)(vii): None.
      Section 5(b)(iv): None.

(b)   "Specified Transaction" will have the meaning specified in Section 14 of
      the Agreement.

(c)   The "Breach of Agreement" provisions of Section 5(a)(ii) of the Agreement
      will be inapplicable to Party A and Party B.

(d)   The "Credit Support Default" provisions of Section 5(a)(iii) of the
      Agreement will be inapplicable to Party B.

(e)   The "Misrepresentation" provisions of Section 5(a)(iv) of the Agreement
      will be inapplicable to Party A and Party B.

(f)   The "Default Under Specified Transaction" provisions of Section 5(a)(v) of
      the Agreement will be inapplicable to Party A and Party B.

(g)   The "Cross Default" provisions of Section 5(a)(vi) of the Agreement will
      be inapplicable to Party A and Party B

(h)   The "Credit Event Upon Merger" provisions of Section 5(b)(iv) of the
      Agreement will be inapplicable to Party A and Party B.

(i)   The "Automatic Early Termination" provision of Section 6(a) of the
      Agreement will be inapplicable to Party A and Party B; provided that where
      there is an Event of Default under Section 5(a)(vii)(1), (3), (4), (5),
      (6) or, to the extent analogous thereto, (8), and the Defaulting Party is
      governed by a system of law that does not permit termination to take place
      after the occurrence of such Event of Default, then the Automatic Early
      Termination provisions of Section 6(a) of the Agreement will apply.

      If an Early Termination Date has occurred under Section 6(a) of the
      Agreement as a result of Automatic Early Termination, and if the
      Non-defaulting Party determines that it has either sustained or incurred a
      loss or damage or benefited from a gain in respect of any Transaction, as
      a result of movement in interest rates, currency exchange rates, other
      relevant rates or market quotations between the Early Termination Date and
      the date upon which the Non-defaulting Party first becomes aware that such
      Event of Default has occurred under Section 6(a), then (i) the amount of
      such loss or damage shall be added to the amount due by the Defaulting
      Party or deducted from the amount due by the Non-defaulting Party, as the
      case may be (in both cases pursuant to Section 6(e)(i)(3) of the
      Agreement); or (ii) the amount of such gain shall be deducted from the
      amount due by the Defaulting Party or added to the amount due by the
      Non-defaulting Party, as the case may be (in both cases pursuant to
      Section 6(e)(i)(3) of the Agreement).

(j)   Payments on Early Termination. For the purpose of Section 6(e) of the
      Agreement:

      (i) Market Quotation will apply; and

      (ii) The Second Method will apply.

(k)   "Termination Currency" means United States Dollars.

(l)   "Additional Termination Event" will not apply, except as provided in Part
      5(m) or in any confirmation.

      on clause (ii) and the other party does not deliver a form or document
      under Section 4(a)(iii) of the Agreement by reason of material prejudice
      to its legal or commercial position.

      Payee Representations. For the purpose of Section 3(f) of this Agreement,
      Party A and Party B make the following representations:

      (i)   Party A represents that it is a corporation organized under the laws

      33-8518, 34-50905; File No. 57-21-0433-8419) applicable to this

      satisfactory to the Securities Administrator within (30) days of such
      Ratings Event that meets or exceeds, or as to which any applicable credit
      support provider meets or exceeds, the Approved Ratings Thresholds (as
      defined below) on terms substantially similar to this Confirmation or (ii)
      deliver collateral, in an amount equal to the Exposure (as defined below),
      and an executed ISDA Credit Support Annex satisfactory to the Securities
      Administrator within (30) days of such Ratings Event and subject to
      Moody's, Fitch's and S&P's written confirmation that delivery of such
      collateral in the context of such downgrade will not result in a
      withdrawal, qualification or downgrade of the then current ratings
      assigned to the Securities. For avoidance of doubt, a downgrade of the
      rating on the Securities could occur in the event that Party A does not
      post sufficient collateral. For purposes of this Transaction, a "Ratings
      Event" shall occur with respect to Party A (or any applicable credit
      support provider), if its short-term unsecured and unsubordinated debt

      (including in connection with a merger, consolidation or other similar
      transaction by Party A or any applicable credit support provider) such
      ratings being referred to herein as the "Approved Ratings Thresholds,"
      (unless, within 30 days thereafter, each of Moody's, Fitch and S&P has
      reconfirmed the ratings of the Securities, as applicable, which was in
      effect immediately prior thereto). Only with respect to such Ratings
      Event, "Exposure" shall mean the greater of the following: (i) the
      mark-to-market value of the Transaction as of the Valuation Date (as such
      term is defined in the ISDA Credit Support Annex); (ii) the amount of the
      next payment due under the Transaction and (iii) one percent of the
      Notional Amount for the respective Calculation Period.

(n)   Additional Termination Event

      Additional Termination Event will apply if a Ratings Event has occurred
      and Party A has not complied with (m) above, then an Additional
      Termination Event shall have occurred with respect to Party A and Party A
      shall be the sole Affected Party with respect to such Additional
      Termination Event.



                                                                       Exhibit A

                                    GUARANTY

To: Wells Fargo Bank, N.A.,, (the "Beneficiary"), not individually, but solely
as Securities Administrator of the ABFC 2005-HE1 Trust - Class M and Class B
Certificates (the "Rated Security")

1. The undersigned, SWISS REINSURANCE COMPANY, a Swiss company (the
"Guarantor"), hereby absolutely and unconditionally guarantees the prompt
payment as and when due of all obligations of its indirect, wholly-owned
subsidiary SWISS RE FINANCIAL PRODUCTS CORPORATION, a Delaware corporation ("THE
GUARANTEED SUBSIDIARY") under, in connection with or ancillary to a long form
confirmation dated as of March 30, 2005 between the Beneficiary and THE
GUARANTEED SUBSIDIARY as amended or restated from time to time (the
"Agreements") which support the issuance of the Rated Security. In this
Guarantee these obligations are referred to as the "Guaranteed Obligations".
This Guarantee is given solely for the benefit of, and is enforceable only by,
the Beneficiary or any trustee as assignee of the Beneficiary to which this
Guarantee has been validly assigned in accordance with applicable law and who is
acting as trustee for the investors in the Rated Securities.

2. This Guarantee constitutes a Guarantee of payment and not of collection and
is not conditional or contingent upon any attempts to collect from, or pursue or
exhaust any rights or remedies against, THE GUARANTEED SUBSIDIARY. A demand for
payment hereunder may at the Beneficiary's option be made in writing addressed
to the Chief Financial Officer of the Guarantor. This Guarantee is not however
dependent in any way on the manner of the demand for payment. Delay in making a
claim will not affect the Guarantor's obligations under this Guarantee unless
the relevant legal limitation period has expired.

3. This Guarantee constitutes, and is intended by the Guarantor to constitute,
an unlimited non-accessory undertaking ("unbeschrankte, nicht akzessorische
Verpflichtung") within the meaning of Article 111 of the Swiss Code of
Obligations (`CO`) and is not a mere surety ("Burgschaft") within the meaning of
Article 492 et seq of the CO.

4. Notwithstanding any reference to the obligations of THE GUARANTEED
SUBSIDIARY, the Guarantor's obligations under this Guarantee are its absolute
and independent obligations as a primary obligor. Payment of a claim hereunder
is required as soon as the Guaranteed Obligations are due and payable.

5. To the extent that any event or circumstance would give rise to any legal or
equitable discharge, defence or other rights of the Guarantor under this
Guarantee, but which event or circumstance would not give rise to any discharge,
defence or other rights of THE GUARANTEED SUBSIDIARY under the Agreements, the
Guarantor hereby fully waives, subject to paragraph 7 below, such discharge,
defence, or other rights and the Guarantor's liability hereunder shall continue
as if such event or circumstance had not arisen.

6. The Guarantor further agrees, subject to paragraph 7 below, that to the
extent that any event or circumstance gives rise to any legal or equitable
discharge, defence or other rights available to both the Guarantor under the
Guarantee and THE GUARANTEED SUBSIDIARY under the Agreements, the Guarantor
hereby agrees to waive such discharge, defense or other rights against the
Beneficiary, until such time as all the Guaranteed Obligations in relation to
the same event or circumstance have been fully met as required to protect
investors in the Rated Securities.

7. Notwithstanding any other provision of this Guarantee, the Guarantor will
have the right, prior to making any payment under this Guarantee, to (a) assert
such rights of offset as are set forth in the Agreements to the extent that such
rights relate to amounts due and payable by the Beneficiary to THE GUARANTEED
SUBSIDIARY and not to amounts which are subject to dispute; and (b) defend
manifestly fraudulent claims under this Guarantee made by the Beneficiary.

8. This Guarantee will continue in full force and effect in relation to all
Guaranteed Obligations until all the Guaranteed Obligations have been satisfied
in full. For the avoidance of doubt, all Guaranteed Obligations entered into by
THE GUARANTEED SUBSIDIARY during the term of this Guarantee shall be honoured in
accordance with this Guarantee and shall be binding on the Guarantor and its
successors and assigns. This Guarantee may be amended only as necessary to
reflect changes to the Guaranteed Obligations which are validly agreed to by the
Beneficiary (or the trustee as assignee of the Beneficiary) in accordance with
the terms of the Rated Securities, including any requirement to obtain the
consent of some or all of the investors in the Rated Securities.

9. If any payment by THE GUARANTEED SUBSIDIARY is avoided, recaptured or reduced
as a result of insolvency or any similar event affecting creditors rights
generally having occurred in respect of THE GUARANTEED SUBSIDIARY, the
Guarantor`s liability under this Guarantee shall continue as if the avoided,
recaptured or reduced payment had not occurred.

10. Upon payment by the Guarantor to the Beneficiary of any amount due under
this Guarantee, the Guarantor shall be entitled to require the assignment to it
of the rights of the Beneficiary against THE GUARANTEED SUBSIDIARY to the extent
satisfied by such payment, and the Beneficiary will take at the Guarantor's
expense such steps as the Guarantor may reasonably require to implement such
assignment. The Guarantor shall not exercise any rights against THE GUARANTEED
SUBSIDIARY which it may acquire in consequence of such payment and assignment
unless and until all the Guaranteed Obligations to the Beneficiary shall have
been paid in full.

11. This Guarantee is governed and will be construed in accordance with Swiss
law. The exclusive place of jurisdiction for any legal proceeding hereunder
shall be Zurich, Switzerland.

IN WITNESS WHEREOF, the Guarantor has caused this Guarantee to be executed in
its name as of the 30th day of March, 2005.
