            This Pooling and Servicing Agreement is dated as of January 1,
2005 (the "Agreement"), among BOND SECURITIZATION, L.L.C., as depositor (the
"Depositor"), CREDIT-BASED ASSET SERVICING AND SECURITIZATION LLC, as seller
(the "Seller"), LITTON LOAN SERVICING LP, as servicer (the "Servicer"), and
U.S. BANK NATIONAL ASSOCIATION, as trustee (the "Trustee").

                             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
nineteen Classes of Certificates, designated as (i) the Class AV-1, Class
AV-2, Class AV-3 Class AF-1, Class AF-2, Class AF-3 and Class AF-4
Certificates, (ii) the Class M-1, Class M-2 and Class M-3 Certificates, (iii)
the Class B-1, Class B-2, Class B-3, Class B-4 and Class B-5 Certificates,
(iv) the Class N Certificates, (v) the Class X Certificates, (vi) the Class R
Certificates and (vii) the Class XR Certificates.

            The Depositor hereby assigns to the Trustee, acting on behalf of
the Certificateholders its interests and rights in the Mortgage Loans. As
provided herein, for federal income tax purposes, the Trustee will elect to
treat the segregated pools of assets subject to this Agreement as nine real
estate mortgage investment conduits (each, a "REMIC"): the Subsidiary REMIC,
the Intermediate REMIC, the Master REMIC, the Class X REMIC and the five Class
B REMICs. The Subsidiary REMIC will consist of (a) all of the assets
constituting the Group 1 Mortgage Loans and all of the assets constituting the
Group 2 Mortgage Loans. The Subsidiary REMIC will issue (1) the REMIC regular
interests (the "Subsidiary REMIC Regular Interests") and (2) the SR Interest.
The Subsidiary REMIC Regular Interests will be uncertificated and will
represent the "regular interests" in the Subsidiary REMIC and the SR Interest
will represent the single class of "residual interest" in the Subsidiary
REMIC.

            The Trustee will hold the Subsidiary REMIC Regular Interests for
the benefit of the Intermediate REMIC. The assets of the Intermediate REMIC
will consist of the Subsidiary REMIC Regular Interests and the interests in
the Intermediate REMIC will be evidenced by (i) the Intermediate REMIC Regular
Interests, which will be uncertificated and will represent the "regular
interests" in the Intermediate REMIC and (ii) the IR Interest, which will
represent the single class of "residual interest" in the Intermediate REMIC.

            The Trustee will hold the Intermediate REMIC Regular Interests for
the benefit of the Master REMIC. The assets of the Master REMIC will consist
of the Intermediate REMIC Regular Interests and the interests in the Master
REMIC will be evidenced by (i) the Regular Certificates (other than the Class
X and Class B Certificates), the Class XM Interest and the five Class BM
Interests, which will represent the "regular interests" in the Master REMIC
and (ii) the Class MR Interest, which will represent the single class of
"residual interest" in the Master REMIC.

            The Trustee will hold the Class XM Interest in the Master REMIC
for the benefit of the Class X REMIC. The assets of the Class X REMIC will
consist of the Class XM Interest in the Master REMIC and interests in the
Class X REMIC will be evidenced by (i) the Class XN

                                     -1-
<PAGE>

Interest, which will represent the "regular interests" in the Class X REMIC
and (ii) the Class XR Interest, which will represent the single class of
"residual interest" in the Class X REMIC. As discussed in section 9.01 of the
Agreement, the Class N and Class X Certificates will represent the beneficial
interest in the Class XN Interest.

            The Trustee will hold each Class BM Interest in the Master REMIC
for the benefit of a separate Class B REMIC. The assets of each Class B REMIC
will consist of a single Class BM Interest in the Master REMIC and interests
in each Class B REMIC will be evidenced by (i) a separately numbered Class B
Certificate, which will represent the "regular interest" in that Class B REMIC
and (ii) a separately numbered, uncertificated Class BR Interest, which will
represent the single class of "residual interest" in that Class B REMIC.

            The Class R Certificates will represent the Class SR, Class IR and
Class MR Interests, and the Class XR Certificates will represent the Class XR
Interests and the residual interest in each of the five Class B REMICs. The
"latest possible maturity date" for federal income tax purposes of all REMICs,
and regular and residual interests created hereunder will be the Latest
Possible Maturity Date.

                             The Subsidiary REMIC
                             --------------------

            The Subsidiary REMIC Interests, each of which (except for the
Class SR Interests) is hereby designated a REMIC regular interest for federal
income tax purposes, will have the principal balances, pass-through rates and
Corresponding Loan Groups as set forth in the following table:

---------------
(1)   Each Class A Interest will have a principal balance initially equal to
      0.9% of the Subordinate Component Balance ("SBC") of its Corresponding
      Loan Group. Each Class B Interest will have a principal balance
      initially equal to 0.1% of the Subordinate Component Balance of its
      Corresponding Loan Group. The initial principal balance of each Class C
      Interest will equal the excess of its corresponding Loan Group over the
      initial aggregate principal balances of the Class A and Class B
      Interests corresponding to such Loan Group.

(2)   A Rate equal to the weighted average of the Adjusted Net Mortgage Rates
      of the Mortgage Loans of the Corresponding Loan Group.

                                     -2-
<PAGE>

(3)   The Class 1-$100 Interest does not pay any interest.

(4)   The Class SR Interest is the sole class of residual interest in the
      Subsidiary REMIC. It has no principal balance and pays no principal or
      interest.

On any Distribution Date:

      (1) Interest will be payable according to the rates or formulas
described above.

      (2) If no Cross-Over Situation exists with respect to any Class of
Interests, then Principal Reductions arising with respect to each Loan Group
will be allocated first to cause the Loan Group's corresponding Class A and
Class B Interests to equal, respectively, 0.9% of the Subordinate Component
Balance ("SCB"), and 0.1% of the SCB as of such Distribution Date, and second
to the Loan Group's corresponding Class C Interest;

      (2) If a Cross-Over Situation exists then:

       (a) if the Calculation Rate in respect of the outstanding Class A and
Class B Interests is less than the Subordinate Cap, Principal Relocation
Payments will be made proportionately to the outstanding Class A Interests
prior to any other Principal Distributions from each such Loan Group; and

      (b) if the Calculation Rate in respect of the outstanding Class A and
Class B Interests is greater than the Subordinate Cap, Principal Relocation
Payments will be made proportionately to the outstanding Class B Interests
prior to any other Principal Distributions from each such Loan Group.

      In each case, Principal Relocation Payments will be made so as to cause
the Calculation Rate in respect of the outstanding Class A and Class B
Interests to equal the Subordinate Cap. With respect to each Loan Group, if
(and to the extent that) the sum of (a) the principal payments comprising the
Principal Remittance Amount received during the Due Period and (b) the
Realized Losses, are insufficient to make the necessary reductions of
principal on the Class A and Class B Interests, then interest will be added to
the Loan Group's other Interests that are not receiving Principal Relocation
Payments, in proportion to their principal balances.

      (c) The outstanding aggregate Class A and Class B Interests will not be
reduced below 1 percent of the excess of (i) the aggregate outstanding
Principal Balances of such Loan Groups as of the end of any Due Period over
(ii) the Certificate Balance of the Senior Certificates related to such Loan
Group as of the related Distribution Date (after taking into account
distributions of principal on such Distribution Date).

      If (and to the extent that) the limitation in paragraph (c) prevents the
distribution of principal to any of the Class A and Class B Interests, and if
the Loan Group's Class C Interest has already been reduced to zero, then the
excess principal from that Loan Group will be paid to the Class C Interests of
the other Loan Group if the aggregate Class A and Class B Interests of such
Loan Group are less than one percent of the SCB. Such payment will be made in
proportion to the principal balances of such Class C Interests. If the Loan
Group of the Class C Interest that receives such payment has a Group Cap below
the Group Cap of the Loan Group

                                     -3-
<PAGE>

making the payment, then the payment will be treated by Subsidiary REMIC as a
Realized Loss. Conversely, if the Loan Group of the Class C Interest that
receives such payment has a Group Cap above the Group Cap of the Loan Group
making the payment, then the payment will be treated by Subsidiary REMIC as a
reimbursement for prior Realized Losses;

                            The Intermediate REMIC
                            ----------------------

Balance, the Pass-Through Rate, and the Corresponding Master REMIC Class for

      Each Designated Regular Interest will represent a REMIC regular interest
in its Corresponding REMIC, will have a principal balance and interest rate
identical to the principal balance and interest rate of its corresponding
Class BM Master REMIC Interest and will have a minimum denomination of $25,000
and additional amounts in $1.00 increments. Each Designated Regular Interest
will be entitled to all amounts payable with respect to its corresponding
Class BM Master REMIC Interest. Each Designated Residual Interest will
represent the sole class of REMIC residual interest in its Corresponding REMIC
and will not be entitled to any amounts payable with respect to its
corresponding Class BM Master REMIC Interest or otherwise.

      The following provisions in the Preliminary Statement are intended to
cause net interest and principal collections in respect of the Mortgage Loans
to be distributed from the Subsidiary REMIC to the Intermediate REMIC, from
the Intermediate REMIC to the Master REMIC, from the Master REMIC to each
Class of Certificates (other than the Class B and Class X Certificates) and to
the Class X REMIC and five Class B REMICs, from the Class X REMIC to the Class
XN Interest and from the Class XN Interest to the Class N and Class X
Certificates, respectively and

                                     -7-
<PAGE>

from each Class B REMIC to the Class B Certificate that represents the
Designated Regular Interest in that Class B REMIC. The Preliminary Statement
will be interpreted and applied consistently with such intent.

      For any purpose for which the pass-through rates is calculated, the
interest rate on the Mortgage Loans shall be appropriately adjusted to account
for the difference between the monthly day count convention of the Mortgage
Loans and the monthly day count convention of the regular interests issued by
each of the REMICs. For purposes of calculating the pass-through rates for
each of the interests issued by the Subsidiary REMIC, the Intermediate REMIC,
the Master REMIC and the Class X REMIC, such rates shall be adjusted to equal
a monthly day count convention based on the actual number of days in the
preceding Due Period and a 360-day year so that the Mortgage Loans and all
regular interests will be using the same monthly day counting convention.

            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 either
            (A) in blank or (B) to "U.S. Bank National Association, as Trustee
            for the C-BASS Mortgage Loan Asset-Backed Certificates, Series
            2005-CB1, without recourse";

            The Trustee agrees to execute and deliver (or cause the Custodian
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.

            The Servicer shall cause the Assignments of Mortgage which were
delivered in blank to be completed and shall cause all Assignments referred to
in Section 2.01(iii) hereof and, to the extent necessary, in Section 2.01(iv)
hereof to be recorded. The Servicer shall be required to deliver such
assignments for recording within 30 days of the Closing Date. The Servicer

                                     -50-
<PAGE>

furnish the Trustee, or its designated agent, with a copy of each Assignment
of Mortgage submitted for recording. In the event that any such Assignment is
lost or returned unrecorded because of a defect therein, the Servicer shall
promptly have a substitute Assignment prepared or have such defect cured, as
the case may be, and thereafter cause each such Assignment to be duly
recorded.

            If any of the documents referred to in Section 2.01(ii), (iii) or
(iv) above has as of the Closing Date been submitted for recording but either
(x) has not been returned from the applicable public recording office or (y)
has been lost or such public recording office has retained the original of
such document, the obligations of the Seller to deliver such documents shall

the case of (y) above to be a true and complete copy of the original that was

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
Seller shall deliver or cause to be delivered to the Trustee or the Custodian
promptly upon receipt thereof any other documents constituting a part of a
Mortgage File received with respect to any Mortgage Loan, including, but not
limited to, any original documents evidencing an assumption or modification of
any Mortgage Loan.

            Upon discovery or receipt of notice of any materially defective
document in, or that a document is missing from, a Mortgage File, the Seller
shall have 120 days to cure such defect or 150 days following the Closing
Date, in the case of missing Mortgages or Assignments or deliver such missing
document to the Trustee or the Custodian. 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.

            In the event that any Mortgage Note is endorsed in blank as of the
Closing Date, promptly following the Closing Date the Seller shall cause to be
completed such endorsements "Pay to the order of U.S. Bank National
Association, as Trustee for the C-BASS Mortgage Loan Asset-Backed
Certificates, Series 2005-CB1, without recourse."

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

            The Depositor and the Trustee on behalf of the Trust understand
and agree that it is not intended that any mortgage loan be included in the
Trust that is a high-cost home loan as defined by HOEPA or any other
applicable predatory or abusive lending laws.

            Section 2.02      Acceptance by Trustee.

            The Trustee acknowledges the receipt of, subject to the provisions
of Section 2.01 and subject to the review described below and any exceptions
noted on the exception report described in the next paragraph below, the
documents referred to in Section 2.01 above and all other assets included in
the definition of "Trust Fund" and declares that it holds and will hold such
documents and the other documents delivered to it constituting a Mortgage
File, and that it

                                     -51-
<PAGE>

holds or will hold all such assets and such other assets included in the
definition of "Trust Fund" in trust for the exclusive use and benefit of all
present and future Certificateholders.

            The Trustee agrees, for the benefit of the Certificateholders, to
review (or cause the Custodian 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, or cause the Custodian to certify, in substantially the form attached
hereto as Exhibit F-1 that, as to each Mortgage Loan listed in the Mortgage
Loan Schedule (other than any Mortgage Loan paid in full or any Mortgage Loan
specifically identified in the exception report annexed thereto as not being
covered by such certification), (i) all documents required to be delivered to
it pursuant to Section 2.01 of this Agreement are in its possession, (ii) such
documents have been reviewed by it and have not been mutilated, damaged or
torn and relate to such Mortgage Loan, (iii) based on its examination and only
as to the foregoing, the information set forth in the Mortgage Loan Schedule
that corresponds to items (1), (2), (3), (5), (13) and (26) (in the case of
(26), only as to whether there is a Prepayment Charge) of the Mortgage Loan
Schedule accurately reflects information set forth in the Mortgage File, (iv)
all Assignments of Mortgage or intervening assignments of mortgage, as
applicable, have been submitted for recording and (v) each Mortgage Note has
been endorsed as provided in Section 2.01(i) of this Agreement and each
Mortgage has been assigned in accordance with Section 2.01(iii) of this
Agreement. It is herein acknowledged that, in conducting such review, the
Trustee (or the Custodian, as applicable) is under no duty or obligation to
inspect, review or examine any such documents, instruments, certificates or
other papers to determine that they are genuine, enforceable, or appropriate
for the represented purpose or that they have actually been recorded or that
they are other than what they purport to be on their face.

            Prior to the first anniversary date of this Agreement the Trustee
shall deliver (or cause the Custodian to deliver) to the Depositor and the
Servicer 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 the Custodian, as applicable) 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, upon its
notification by the Custodian, if applicable, shall so notify the Seller, the
Depositor and the Servicer. In addition, upon the discovery by the Seller,
Depositor, or the Servicer (or upon receipt by the Trustee of written
notification of such breach) of a breach of any of the representations and
warranties made by the Seller in the related 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

                                     -52-
<PAGE>

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 this
Agreement shall constitute a security agreement under applicable law and 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 (i) each
Mortgage Loan identified on the Mortgage Loan Schedule, including the related
Cut-off Date Principal Balance, all interest accruing thereon after the
Cut-off Date and all collections in respect of interest and principal due
after the Cut-off Date; (ii) the Mortgage File for each such Mortgage Loan;
(iii) property which secured each 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 and all rights under
the related FHA Insurance Contracts and VA Guaranties; (v) all proceeds of any
of the foregoing; (vi) the rights of the Depositor under the Mortgage Loan
Purchase Agreement; and (vii) all other assets included or to be included in
the Trust Fund.

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

            (a) Upon discovery or receipt of written notice of any materially
defective document in, or that a document is missing from, a Mortgage File or
of the breach by the Seller of any representation, warranty or covenant under
the Mortgage Loan Purchase Agreement or in Section 2.04 in respect of any
Mortgage Loan which materially adversely affects the value of such Mortgage
Loan or the interest therein of the Certificateholders, the Trustee (or the
Custodian, as applicable) shall promptly notify the Seller and the Servicer of
such defect, missing document or breach and request that the Seller deliver
such missing document or cure such defect or breach within 120 days or 150
days following the Closing Date, in the case of missing Mortgages or
Assignments from the date the Seller was notified of such missing document,
defect or breach, and if the Seller does not deliver such missing document or
cure such defect or breach in all material respects during such period, the
Trustee, shall enforce the Seller's obligation under the Mortgage Loan
Purchase Agreement and inform the Seller of its obligation 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 120 day period (subject to
Section 2.03(e)); provided that, in connection with any such breach that could
not reasonably have been cured within such 120 day or 150 day period, if the
Seller shall have commenced to cure such breach within such 120 day or 150 day
period, the Seller shall be permitted to proceed thereafter diligently and
expeditiously to cure the same within the additional period provided under the
Mortgage Loan Purchase Agreement. The Purchase Price for the repurchased
Mortgage Loan shall be deposited in the Collection Account, and the Trustee,
upon receipt of written certification from the Servicer of such deposit, shall
release to the Seller the related Mortgage File and shall execute and deliver
such instruments of transfer or assignment, in each case without recourse, as
the Seller shall furnish to it and as shall be necessary to vest in the Seller
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 Seller 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(d). In addition to the foregoing, in case of a breach of
the Seller's representation set forth in Section 3.01(f) of the Mortgage Loan
Purchase Agreement, the Seller shall reimburse the Trust for all costs or
damages incurred by the Trust as a result of a violation of any predatory or

                                     -53-
<PAGE>

abusive lending laws referred to therein (such amount, the "Reimbursement
Amount"). The Reimbursement Amount shall be delivered to the Servicer for
deposit into the Collection Account within 10 days from the date the Seller
was notified by the Trustee of the amount of all costs and damages. It is
understood and agreed that the obligation of the Seller to pay the
Reimbursement Amount for deposit into the Collection Account and either to
cure or to repurchase (or to substitute for) any Mortgage Loan as to which a
document is missing, a material defect in a constituent document exists or as
to which such a breach has occurred and is continuing shall constitute the
sole remedy against the Seller respecting such omission, defect or breach
available to the Trustee, on behalf of the Certificateholders.

            (b) [Reserved].

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

            (d) Any substitution of Eligible Substitute Mortgage Loans for
Defective Mortgage Loans made pursuant to Section 2.03(a) must be effected
prior to the last Business Day that is within two years after the Closing
Date. As to any Defective Mortgage Loan for which the Seller substitutes an
Eligible Substitute Mortgage Loan or Loans, such substitution shall be
effected by the Seller delivering to the Trustee, for such Eligible Substitute
Mortgage Loan or Loans, the Mortgage Note, the Mortgage, the Assignment to the
Trustee, and such other documents and agreements, with all necessary
endorsements thereon, as are required by Section 2.01, together with an
Officers' Certificate providing that each such Eligible Substitute Mortgage
Loan satisfies the definition thereof and specifying the Substitution
Adjustment Amount (as described below), if any, in connection with such
substitution. The Trustee shall acknowledge receipt for such Eligible
Substitute Mortgage Loan or Loans and, within ten Business Days thereafter,
shall review such documents as specified in Section 2.02 and deliver (or cause
the Custodian to deliver) to the Servicer, with respect to such Eligible
Substitute Mortgage Loan or Loans, a certification substantially in the form
attached hereto as Exhibit F-1, with any applicable exceptions noted thereon.
Within one year of the date of substitution, the Trustee shall deliver (or
cause the Custodian to deliver) to the Servicer a certification substantially
in the form of Exhibit F-2 hereto with respect to such Eligible Substitute
Mortgage Loan or Loans, with any applicable exceptions noted thereon. Monthly
Payments due with respect to Eligible Substitute Mortgage Loans in the month
of substitution are not part of the Trust Fund and will be retained by the
Seller. 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 preceding the month of substitution and
the Depositor 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 Seller shall give or cause to be given written notice to
the Certificateholders that such substitution has taken place, shall amend the
Mortgage Loan Schedule to reflect the removal of such Defective Mortgage Loan
from the terms of this Agreement and the substitution of the Eligible
Substitute Mortgage Loan or Loans and shall deliver a copy of such amended
Mortgage Loan Schedule to the Trustee. 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

                                     -54-
<PAGE>

of a substitution effected by the Seller, the Mortgage Loan Purchase
Agreement, including, in the case of a substitution effected by the Seller all
applicable representations and warranties thereof included in the Mortgage
Loan Purchase Agreement and all applicable representations and warranties
thereof set forth in Section 2.04, in each case as of the date of
substitution.

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

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

            (e) Upon discovery by the Seller, the Servicer or the Trustee that
any Mortgage Loan does not constitute a "qualified mortgage" within the
meaning of Section 860G(a)(3) of the Code, the party discovering such fact
shall within two Business Days give written notice thereof to the other
parties. In connection therewith, the Seller shall repurchase or, subject to
the limitations set forth in Section 2.03(d), 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 Seller shall cure the
defect or make the required purchase or substitution no later than 90 days
after the earlier of the discovery of the defect and receipt of notification
of the defect. Any such repurchase or substitution shall be made in the same
manner as set forth in Section 2.03(a), if made by the Seller. The Trustee
shall reconvey to the Seller the Mortgage Loan to be released pursuant hereto
in the same manner, and on the same terms and conditions, as it would a
Mortgage Loan repurchased for breach of a representation or warranty.

            Notwithstanding anything to the contrary contained herein, the
parties hereto acknowledge that the functions of the Trustee, with respect to
the custody, acceptance, inspection and release of the Mortgage Files pursuant
to Sections 2.01, 2.02 and 2.03 and preparation and

                                     -55-
<PAGE>

delivery of the certifications in the form of Exhibit F-1 and Exhibit F-2
shall be performed by the Custodian pursuant to the terms and conditions of
the Custodial Agreement. The fees and expenses of the Custodian shall be paid
by the Servicer.

            Section 2.04 Representations and Warranties of the Seller with
Respect to the Mortgage Loans.

            The Seller hereby represents and warrants to the Trustee for the
benefit of the Certificateholders that as of the Closing Date or as of such
other date specifically provided herein:

            (a) The representations and warranties made by the Seller pursuant
to Section 3.01 of the Mortgage Loan Purchase Agreement are hereby being made
to the Trustee and are true and correct as of the Closing Date.

            (b) Any written agreement between the Mortgagor in respect of a
Mortgage Loan and the Servicer modifying such Mortgagor's obligation to make
payments under the Mortgage Loan (such modified Mortgage Loan, a "Modified
Mortgage Loan") involved the application of some assessment of the Mortgagor's
ability to repay the Modified Mortgage Loan.

            With respect to the representations and warranties set forth in
this Section 2.04 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 Depositor, the
Seller, the Servicer, the Custodian 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 or the interest
therein of the Certificateholders 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 Depositor, the Seller, the Servicer or the
Trustee of a breach of any of the representations and warranties contained in
this Section that materially and adversely affects the value of any Mortgage
Loan or the interest therein of the Certificateholders, the party discovering
the breach shall give prompt written notice to the others and in no event
later than two Business Days from the date of such discovery. Within ninety
days of its discovery or its receipt of notice of any such missing or
materially defective documentation or any such breach of a representation or
warranty, the Seller shall promptly deliver such missing document or cure such
defect or breach in all material respects, or in the event such defect or
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.

            It is understood and agreed that the representations and
warranties set forth in this Section 2.04 shall survive delivery of the
Mortgage Files to the Trustee 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 2.04 to cure, substitute for or repurchase a Mortgage
Loan pursuant to the Mortgage Loan

      presently conducted, and is licensed, qualified and in good standing in
      the states where the Mortgaged Property is located if the laws of such

      Servicer unable to comply with HUD, Fannie Mae, Freddie Mac, FHA or VA

      ability of the Servicer to carry on its business substantially as now
      conducted, or in any material liability on the part of the Servicer, or
      that would draw into question the validity or enforceability of this
      Agreement or of any action taken or to be taken in connection with the
      obligations of the Servicer contemplated herein, or that would be likely
      to impair materially the ability of the Servicer to perform under the

      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.

            (ix) There are no actions or proceedings against, or
      investigations of, the Seller pending or, to its knowledge, threatened,

      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.

            (a) The Seller hereby covenants that except for the transfer to
the Depositor, 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 Depositor, of the existence of any lien on any

Trust, as assignee of the Depositor, 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 2.09 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.

            (b) The Seller hereby covenants that neither it nor any Affiliate
of the Seller will directly solicit any Mortgagor hereunder to refinance the
related Mortgage Loan. For the purposes of the foregoing, neither the Seller
nor any Affiliate of the Seller shall be deemed to directly solicit any
Mortgagor if the Seller responds to a request from a Mortgagor regarding a
refinancing or if the Mortgagor receives marketing materials which are
generally disseminated.

                                 ARTICLE III

                         ADMINISTRATION AND SERVICING
                               OF THE TRUST FUND

            Section 3.01      Servicer to Act as Servicer.

            The Servicer, as independent contract servicer, shall service and
administer the Mortgage Loans in accordance with this Agreement and the normal
and usual standards of practice of prudent mortgage servicers, and shall have
full power and authority, acting alone, to do or cause to be done any and all
things in connection with such servicing and administration which the Servicer
may deem necessary or desirable and consistent with the terms of this
Agreement including, in the case of FHA Loans and VA Loans, taking all actions
that a mortgagee is permitted or required to take by the FHA or the VA, as
applicable (the "Servicing Standards").

            Consistent with the terms of this Agreement, the Servicer may
waive, modify or vary any term of any Mortgage Loan or consent to the
postponement of strict compliance with any such term or in any manner grant
indulgence to any Mortgagor if in the Servicer's reasonable and prudent
determination such waiver, modification, postponement or indulgence is not
materially adverse to the Certificateholders; provided, however that the
Servicer shall not make future advances and (unless the Mortgagor is in
default with respect to the Mortgage Loan or such default is, in the judgment
of the Servicer, reasonably foreseeable) the Servicer shall not permit any
modification with respect to any Mortgage Loan that would (i) change the
Mortgage Interest Rate, defer or forgive the payment thereof of any principal
or interest payments, reduce the outstanding principal amount (except for
actual payments of principal) or extend the final maturity date with respect
to such Mortgage Loan, (ii) in the case of FHA Loans, affect the FHA Insurance
Contract with respect to any such Mortgage Loan and in the case of VA Loans,
affect the VA Guaranty with respect to such Mortgage Loan, (iii) affect
adversely the status of any REMIC as a REMIC or (iv) cause any REMIC to be
subject to a tax on "prohibited transactions" or "contributions" pursuant to
the REMIC Provisions. Notwithstanding the foregoing, the Servicer shall not
permit any modification with respect to any Mortgage Loan that would both (x)
effect an exchange or reissuance of such Mortgage Loan under Section
1.860G-2(b) of the

                                     -63-
<PAGE>

Treasury regulations and (y) cause any REMIC constituting part of the Trust
Fund to fail to qualify as a REMIC under the Code or the imposition of any tax
on "prohibited transactions" or "contributions" after the Startup Day under
the REMIC Provisions. Without limiting the generality of the foregoing, the
Servicer shall continue, and is hereby authorized and empowered to execute and
deliver on behalf of itself, and the Trustee, all instruments of satisfaction
or cancellation, or of partial or full release, discharge and all other
comparable instruments, with respect to the Mortgage Loans and with respect to
the Mortgaged Property. The Servicer shall make all required Servicing
Advances and shall service and administer the Mortgage Loans in accordance
with Applicable Regulations, and shall provide to the Mortgagor any reports
required to be provided to them thereby. If reasonably required by the
Servicer, the Trustee shall furnish the Servicer with a power of attorney
substantially in the form of Exhibit X hereto and other documents necessary or
appropriate to enable the Servicer to carry out its servicing and
administrative duties under this Agreement and the Trustee shall have no
liability with respect to any misuse of such power of attorney and shall be
indemnified by Servicer for any costs, liabilities or expenses incurred by the
Trustee in connection therewith. The Trustee agrees to provide such powers of
attorney within ten (10) days of the Servicer's request therefor.

            In servicing and administering FHA Loans, the Servicer shall
comply strictly with the National Housing Act and the FHA Regulations and
administrative guidelines issued thereunder or pursuant thereto (insofar as
the same apply to any Mortgage Loan) and, to the extent permitted hereunder,
promptly discharge all of the obligations of the mortgagee thereunder and
under each Mortgage including the timely giving of notices, the essence hereof
being that the full benefits of each FHA Insurance Contract inure to the
Trustee, on behalf of the Certificateholders.

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

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

            Notwithstanding anything in this Agreement to the contrary, in the
event of a Principal Prepayment in full of a Mortgage Loan, the Servicer may
not waive any Prepayment Charge or portion thereof required by the terms of
the related Mortgage Note unless (i) the Servicer determines that such waiver
would maximize recovery of Liquidation Proceeds for such Mortgage Loan, taking
into account the value of such Prepayment Charge, (ii) (A) the enforceability
thereof is limited (1) by bankruptcy, insolvency, moratorium, receivership, or
other similar law relating to creditors' rights generally or (2) due to
acceleration in connection with a foreclosure or other involuntary payment, or
(B) the enforceability is otherwise limited or prohibited by applicable law or
(iii) the Servicer has not been provided with information sufficient to enable
it to collect the Prepayment Charge. In the event of a Principal Prepayment in
full with respect to any Mortgage Loan, the Servicer shall deliver to the
Trustee an Officer's Certificate substantially in the form of Exhibit Q no
later than the date on which the Servicer

                                     -64-
<PAGE>

delivers the Remittance Report to the Trustee and the Trustee will make such
Officer's Certificate available on its website to the Class X
Certificateholder. If the Servicer has waived or does not collect all or a
portion of a Prepayment Charge relating to a Principal Prepayment in full due
to any action or omission of the Servicer, other than as provided above, the
Servicer shall, within 90 days of the date on which the Principal Prepayment
in full is remitted to the Trustee, deliver to the Trustee the amount of such
Prepayment Charge (or such portion thereof as had been waived for deposit)
into the Distribution Account for distribution in accordance with the terms of
this Agreement.

            The Trustee shall prepare and deliver to the Depositor and the
owner of the Class N and Class X Certificates, on a monthly basis, a statement
setting forth the amounts due and received with respect to Prepayment Charges.

            Section 3.02      Collection of Mortgage Loan Payments.

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

            Section 3.03      Realization Upon Defaulted Mortgage Loans.

            In the event that any payment due under any Conventional Mortgage
Loan is not paid when the same becomes due and payable, or in the event the
Mortgagor fails to perform any other covenant or obligation under the Mortgage
Loan and such failure continues beyond any applicable grace period, the
Servicer shall take such action as it shall deem to be in the best interest of
the Certificateholders. In the event that any payment due under any FHA Loan
becomes delinquent, the Servicer shall take all such actions as are in the
best interests of the Certificateholders and permitted under any applicable
FHA loss mitigation proceedings, including, but not limited to, requesting the
FHA to accept an assignment of such FHA Loan, and, upon the Servicer's
determination that foreclosure is in the best interest of the
Certificateholders, commencing foreclosure proceedings. With respect to any
defaulted Mortgage Loan, the Servicer shall have the right to review the
status of the related forbearance plan and, subject to the second paragraph of
Section 3.01, may modify such forbearance plan; including, extending the
Mortgage Loan repayment date for a period of one year or reducing the Loan
Rate up to 50 basis points.

            In connection with a foreclosure or other conversion, the Servicer
shall exercise such rights and powers vested in it hereunder and use the same
degree of care and skill in its exercise as prudent mortgage servicers would
exercise or use under the circumstances in the

                                     -65-
<PAGE>

conduct of their own affairs and consistent with Applicable Regulations and
the servicing standards set forth in the Fannie Mae Guide, including, without
limitation, advancing funds for the payment of taxes and insurance premiums
with respect to first lien Mortgage Loans.

            Notwithstanding the foregoing provisions of this Section 3.03,
with respect to any Mortgage Loan as to which the Servicer has received actual
notice of, or has actual knowledge of, the presence of any toxic or hazardous
substance on the related Mortgaged Property, the Servicer shall not either (i)
obtain title to such Mortgaged Property as a result of or in lieu of
foreclosure or otherwise, or (ii) otherwise acquire possession of, or take any
other action with respect to, such Mortgaged Property if, as a result of any
such action, the Trust Fund would be considered to hold title to, to be a
mortgagee-in-possession of, or to be an owner or operator of such Mortgaged
Property within the meaning of the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, as amended from time to time, or any
comparable law, unless the Servicer has also previously determined, based on
its reasonable judgment and a prudent report prepared by a Person who
regularly conducts environmental audits using customary industry standards,
that:

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

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

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

            If the Servicer determines, as described above, that it is in the
best economic interest of the Certificateholders to take such actions as are
necessary to bring any such Mortgaged Property into compliance with applicable
environmental laws, or to take such action with respect to the containment,
clean-up or remediation of hazardous substances, hazardous materials,
hazardous wastes, or petroleum-based materials affecting any such Mortgaged
Property, then the Servicer shall take such action as it deems to be in the
best economic interest of the Certificateholders. The cost of any such
compliance, containment, cleanup or remediation shall be advanced by the
Servicer, subject to the Servicer's right to be reimbursed therefor from the
Collection Account as provided in Section 3.05(ii).

            Section 3.04      Collection Account and Distribution Account.

            (a) The Servicer shall segregate and hold all funds collected and
received pursuant to each Mortgage Loan separate and apart from any of its own
funds and general assets

                                     -66-
<PAGE>

and shall establish and maintain one or more Collection Accounts.  Each
Collection Account shall be an Eligible Account.

            The Servicer shall deposit in the Collection Account on a daily
basis within two Business Days of receipt, and retain therein, the following
payments and collections received or made by it after the Cut-off Date with
respect to the Mortgage Loans:

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

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

            (iii) all Net Liquidation Proceeds and Subsequent Recoveries;

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

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

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

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

            (b) On behalf of the Trust Fund, the Trustee shall establish and
maintain one or more accounts (such account or accounts, the "Distribution
Account"), held in trust for the benefit of the Certificateholders. On behalf
of the Trust Fund, the Servicer shall deliver to the Trustee in immediately
available funds for deposit in the Distribution Account by the close of
business New York time on the Servicer Remittance Date, that portion of the
Available Funds (calculated without regard to the references in the definition
thereof to amounts that may be deposited to the Distribution Account from a
different source as provided herein) then on deposit in the Collection
Account.

            (c) Funds in the Collection Account may be invested in Permitted
Investments in accordance with the provisions set forth in Section 3.25. The
Servicer shall give notice to the Trustee of the location of the Collection
Account maintained by it when established and prior to

                                     -67-
<PAGE>

any change thereof. The Trustee shall give notice to the Servicer and the
Depositor of the location of the Distribution Account when established and
prior to any change thereof.

            (d) In the event the Servicer shall deliver to the Trustee for
deposit in the Distribution Account any amount not required to be deposited
therein, it may at any time request that the Trustee withdraw such amount from
the Distribution Account and remit to the Servicer any such amount, any
provision herein to the contrary notwithstanding. In addition, the Servicer
shall deliver to the Trustee from time to time for deposit, and the Trustee
shall so deposit, in the Distribution Account:

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

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

            (iii) any Prepayment Charges or amounts in connection with the
      waiver of such Prepayment Charges, in each case required to be deposited
      pursuant to Section 3.01;

            (iv) any amounts required to be deposited in the Distribution
      Account pursuant to Sections 3.04, 3.15, 3.16, 3.22 or 4.07; and

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

            (e) Promptly upon receipt of any Stayed Funds, whether from the
Servicer, a trustee in bankruptcy, or federal bankruptcy court or other
source, the Trustee shall notify the Servicer of such receipt and deposit such
funds in the Distribution Account, subject to withdrawal thereof as permitted
hereunder.

            Section 3.05      Permitted Withdrawals From the Collection
Account.

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

            (i) to remit to the Trustee for deposit in the Distribution
      Account the amounts required to be so remitted pursuant to Sections
      3.04(b) and 3.04(d);

            (ii) to reimburse itself for Advances and Servicing Advances; the
      Servicer's right to reimburse itself pursuant to this subclause (ii)
      being limited to amounts received on the related Mortgage Loan which
      represent payments of (a) principal and/or interest respecting which any
      such Advance was made or (b) Condemnation Proceeds, Insurance Proceeds
      or Liquidation Proceeds respecting which any such Servicing Advance was
      made;

          (iii) to reimburse itself for unreimbursed Servicing Advances, any
     unpaid Servicing Fees and for unreimbursed Advances to the extent that
     such amounts are deemed to be Nonrecoverable Advances (including those
     deemed to be Nonrecoverable

                                     -68-
<PAGE>

     Advances at the time a Mortgage Loan is modified), and to reimburse
     itself for such amounts to the extent that such amounts are
     nonrecoverable from the disposition of REO Property pursuant to Section
     3.03 or Section 3.13 hereof;

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

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

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

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

            (viii) to reimburse itself for Advances from amounts in the
      Collection Account held for future distributions that were not included
      in Available Funds for the preceding Distribution Date. An amount equal
      to the amount withdrawn from the Collection Account pursuant to this
      subclause (viii) shall be deposited in the Collection Account by the
      Servicer on the next succeeding Distribution Date that such funds are to
      be distributed to Certificateholders.

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

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

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

            The Servicer shall deposit in the Escrow Account on a daily basis
within two Business Days of receipt, and retain therein, (i) all Escrow
Payments collected on account of the Mortgage Loans, for the purpose of
effecting timely payment of any such items as required under the terms of this
Agreement, and (ii) all Insurance Proceeds which are to be applied to the
restoration or repair of any Mortgaged Property. The Servicer shall make
withdrawals therefrom only to effect such payments as are required under this
Agreement, and for such other purposes as shall be set forth in, or in
accordance with, Section 3.07. The Servicer shall be entitled to retain any
interest paid on funds deposited in the Escrow Account by the depository
institution other than interest on escrowed funds required by law to be paid
to the Mortgagor and, to the

                                     -69-
<PAGE>

extent required by the related Mortgage Loan or Applicable Regulations, the
Servicer shall pay interest on escrowed funds to the Mortgagor notwithstanding
that the Escrow Account is non-interest bearing or that interest paid thereon
is insufficient for such purposes.

            Section 3.07      Permitted Withdrawals From Escrow Account.

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

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

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

            With respect to each first lien Mortgage Loan, the Servicer shall
maintain accurate records reflecting the status of ground rents, taxes,
assessments, water rates and other charges which are or may become a lien upon
the Mortgaged Property and fire, flood and hazard insurance coverage and shall
obtain, from time to time, all bills for the payment of such charges
(including renewal premiums) and shall effect payment thereof prior to the
applicable penalty or termination date and at a time appropriate for securing
maximum discounts allowable, employing for such purpose deposits of the
Mortgagor in the Escrow Account which shall have been estimated and
accumulated by the Servicer in amounts sufficient for such purposes, as
allowed under the terms of the Mortgage or Applicable Regulations. To the
extent that a Mortgage does not provide for Escrow Payments, (i) the Servicer
shall determine whether any such payments are made by the Mortgagor in a
manner and at a time that is necessary to avoid the loss of the Mortgaged
Property due to a tax sale or the foreclosure as a result of a tax lien and
(ii) the Servicer shall ensure that all insurance required to be maintained on
the Mortgaged Property pursuant to this Agreement is maintained. If any such
payment has not been made and

                                     -70-
<PAGE>

the Servicer receives notice of a tax lien with respect to the Mortgage Loan
being imposed, the Servicer will, to the extent required to avoid loss of the
Mortgaged Property, advance or cause to be advanced funds necessary to
discharge such lien on the Mortgaged Property. The Servicer assumes full
responsibility for the payment of all such bills and shall effect payments of
all such bills irrespective of the Mortgagor's faithful performance in the
payment of same or the making of the Escrow Payments and shall make Servicing
Advances from its own funds to effect such payments.

            In connection with its activities as servicer, the Servicer agrees
to prepare and present, on behalf of itself and the Trustee, claims to the
insurer under any Primary Insurance Policy in a timely fashion in accordance
with the terms of such policies and, in this regard, to take such action as
shall be necessary to permit recovery under any Primary Insurance Policy
respecting a defaulted Mortgage Loan. Pursuant to Section 3.04, any amounts
collected by the Servicer under any Primary Insurance Policy shall be
deposited in the Collection Account, subject to withdrawal pursuant to Section
3.05.

            Section 3.09      Transfer of Accounts.

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

            Section 3.10      Maintenance of Hazard Insurance.

            The Servicer shall cause to be maintained for each first lien
Mortgage Loan fire and hazard insurance with extended coverage as is customary
in the area where the Mortgaged Property is located in an amount which is at
least equal to the lesser of (i) the amount necessary to fully compensate for
any damage or loss to the improvements which are a part of such property on a
replacement cost basis, (ii) the Principal Balance of the Mortgage Loan, in
each case in an amount not less than such amount as is necessary to prevent
the Mortgagor and/or the Mortgagee from becoming a co-insurer or (iii) the
amount required under applicable HUD/FHA/VA regulations. If the Mortgaged
Property is in an area identified in the Federal Register by the Flood
Emergency Management Agency as having special flood hazards and flood
insurance has been made available, the Servicer will cause to be maintained a
flood insurance policy meeting the requirements of the current guidelines of
the Federal Insurance Administration with a generally acceptable insurance
carrier, in an amount representing coverage not less than the least of (i) the
Principal Balance of the Mortgage Loan, (ii) the maximum insurable value of
the improvements securing such Mortgage Loan or (iii) the maximum amount of
insurance which is available under the Flood Disaster Protection Act of 1973,
as amended. The Servicer shall also maintain on the REO Property for the
benefit of the Certificateholders, (x) fire and hazard insurance with extended
coverage in an amount which is at least equal to the replacement cost of the
improvements which are a part of such property, (y) public liability insurance
and, (z) to the extent required and available under the Flood Disaster
Protection Act of 1973, as amended, flood insurance in an amount as provided
above. Any amounts collected by the Servicer under any such policies other
than amounts to be deposited in the Escrow Account and applied to the
restoration or repair of the Mortgaged Property or REO Property, or released

                                     -71-
<PAGE>

to the Mortgagor in accordance with the Servicer's normal servicing
procedures, shall be deposited in the Collection Account, subject to
withdrawal pursuant to Section 3.05. It is understood and agreed that no
earthquake or other additional insurance is required to be maintained by the
Servicer or the Mortgagor or maintained on property acquired in respect of the
Mortgage Loan, other than pursuant to such Applicable Regulations as shall at
any time be in force and as shall require such additional insurance. All such
policies shall be endorsed with standard mortgagee clauses with loss payable
to the Servicer and shall provide for at least thirty days prior written
notice of any cancellation, reduction in the amount of or material change in
coverage to the Servicer. The Servicer shall not interfere with the
Mortgagor's freedom of choice in selecting either his insurance carrier or
agent, provided, however, that the Servicer shall not accept any such
insurance policies from insurance companies unless such companies currently
reflect a general policy rating of B:VI or better in Best's Key Rating Guide
and are licensed to do business in the state wherein the property subject to
the policy is located.

            Section 3.11      Maintenance of Mortgage Impairment Insurance
Policy.

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

            Section 3.12      Fidelity Bond, Errors and Omissions Insurance.

            The Servicer shall maintain, at its own expense, a blanket
fidelity bond (the "Fidelity Bond") and an errors and omissions insurance
policy, with broad coverage with financially responsible companies on all
officers, employees or other persons acting in any capacity with regard to the
Mortgage Loans to handle funds, money, documents and papers relating to the
Mortgage Loans. The Fidelity Bond and errors and omissions insurance shall be
in the form of the Mortgage Banker's Blanket Bond and shall protect and insure
the Servicer against losses, including forgery, theft, embezzlement, fraud,
errors and omissions and negligent acts of such persons. Such Fidelity Bond
shall also protect and insure the Servicer against losses in connection with
the failure to maintain any insurance policies required pursuant to this
Agreement and the release or satisfaction of a Mortgage Loan without having
obtained payment

                                     -72-
<PAGE>

in full of the indebtedness secured thereby. No provision of this Section 3.12
requiring the Fidelity Bond and errors and omissions insurance shall diminish
or relieve the Servicer from its duties and obligations as set forth in this
Agreement. The minimum coverage under any such bond and insurance policy shall
be at least equal to the corresponding amounts required by Fannie Mae in the
Fannie Mae MBS Selling and Servicing Guide or by Freddie Mac in the Freddie
Mac Servicer's Guide. Upon request of the Trustee, the Servicer shall cause to
be delivered to the Trustee a certified true copy of the Fidelity Bond and
errors and omissions insurance policy and a statement from the surety and the
insurer that such Fidelity Bond and errors and omissions insurance policy
shall in no event be terminated or materially modified without thirty days'
prior written notice to the Trustee.

            Section 3.13      Title, Management and Disposition of REO Property.

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

            (b) In the event that the Trust Fund acquires any REO Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Servicer shall dispose of such REO Property before the end
of the third calendar year beginning after the year of its acquisition by the
Trust Fund for purposes of Section 860G(a)(8) of the Code or, at the expense
of the Trust Fund, request from the Internal Revenue Service, more than 60
days before the day on which the above-mentioned grace period would otherwise
expire, an extension of the above-mentioned grace period, unless the Servicer
obtains an Opinion of Counsel, addressed to the Servicer and the Trustee, to
the effect that the holding by the Trust Fund of such REO Property subsequent
to such period will not: (i) result in the imposition of any tax on
"prohibited transactions" as defined in Section 860F of the Code; or (ii)
cause any REMIC constituting any part of the Trust Fund to fail to qualify as
a REMIC at any time that any Certificates are outstanding, in which case the
Trust Fund may continue to hold such REO Property (subject to any conditions
contained in such Opinion of Counsel). The Servicer shall be entitled to be
reimbursed from the Collection Account for any costs incurred in obtaining
such Opinion of Counsel, as provided in Section 3.05.

            Subject to compliance with applicable laws and regulations as
shall at any time be in force, and notwithstanding any other provisions of
this Agreement, no REO Property acquired by the Trust Fund shall be rented (or
allowed to continue to be rented) or otherwise used by or on behalf of the
Trust Fund in such a manner or pursuant to any terms that would: (i) cause
such REO Property to fail to qualify as "foreclosure property" within the
meaning of Section 860G(a)(8) of the Code; or (ii) subject any REMIC
constituting part of the Trust Fund to the

                                     -73-
<PAGE>

imposition of any federal income taxes on the income earned from such REO
Property, including any taxes imposed by reason of Sections 860F or 860G(c) of
the Code, unless the Servicer has agreed to indemnify and hold harmless the
Trust Fund with respect to the imposition of any such taxes.

            The Servicer shall manage, conserve, protect and operate each REO
Property for the Certificateholders and the Trust Fund solely for the purpose
of its prompt disposition and sale in a manner which does not cause such REO
Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code or result in the receipt by the related REMIC
of any "income from non-permitted assets" within the meaning of Section
860F(a)(2)(B) of the Code, or any "net income from foreclosure property" which
is subject to taxation under the REMIC Provisions. The Servicer shall cause
each REO Property to be inspected promptly upon the acquisition of title
thereto and shall cause each REO Property to be inspected at least annually
thereafter. The Servicer shall make or cause to be made a written report of
each such inspection. Such reports shall be retained in the Mortgage Servicing
File and copies thereof shall be forwarded by the Servicer to the Trustee upon
request. The Servicer shall attempt to sell the same (and may temporarily rent
the same) on such terms and conditions as the Servicer deems to be in the best
interest of the Certificateholders and the Trust Fund.

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

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

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

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

            Each REO Disposition shall be carried out by the Servicer at such
price and upon such terms and conditions as the Servicer deems to be in the
best interest of the Certificateholders. If as of the date title to any REO
Property was acquired by the Servicer there were outstanding unreimbursed
Servicing Advances with respect to the REO Property, the Servicer, upon an REO
Disposition of such REO Property, shall be entitled to reimbursement for any
related unreimbursed Servicing Advances from proceeds received in connection
with such REO Disposition. The proceeds from the REO Disposition, net of any
payment to the Servicer as provided above, shall be deposited in the
Collection Account for distribution on the succeeding Servicer Remittance Date
in accordance with Section 4.01.

                                     -74-
<PAGE>

            Any REO Disposition shall be for cash only (unless changes in the
REMIC Provisions made subsequent to the Startup Day allow a sale for other
consideration and an Opinion of Counsel is obtained by the Servicer to the
effect that such sale shall not cause any REMIC constituting part of the Trust
Fund to fail to qualify as a REMIC).

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

            When a Mortgaged Property has been or is about to be conveyed by
the Mortgagor, the Servicer shall, except as set forth below, to the extent it
has knowledge of such conveyance or prospective conveyance, exercise its
rights to accelerate the maturity of the related Mortgage Loan under any
"due-on-sale" clause contained in the related Mortgage or Mortgage Note;
provided, however, that the Servicer shall not exercise any such right if the
"due-on-sale" clause, in the reasonable belief of the Servicer, is not
enforceable under applicable law. An Opinion of Counsel at the expense of the
Servicer (which expense shall constitute a Servicing Advance) delivered to the
Trustee and the Depositor to the foregoing effect shall conclusively establish
the reasonableness of such belief. In such event, the Servicer shall make
reasonable efforts to enter into an assumption and modification agreement with
the Person to whom such property has been or is about to be conveyed, pursuant
to which such Person becomes liable under the Mortgage Note and, unless
prohibited by applicable law or the Mortgage, the Mortgagor remains liable
thereon. If the foregoing is not permitted under applicable law, the Servicer
is authorized to enter into a substitution of liability agreement with such
Person, pursuant to which the original Mortgagor is released from liability
and such Person is substituted as Mortgagor and becomes liable under the Note.
In addition to the foregoing, the Servicer shall not be required to enforce
any "due-on-sale" clause if in the reasonable judgment of the Servicer,
entering into an assumption and modification agreement with a person to whom
such property shall be conveyed and releasing the original Mortgagor from
liability would be in the best interest of the Certificateholders.

            The Mortgage Loan, as assumed, shall conform in all respects to
the requirements, representations and warranties of this Agreement. The
Servicer shall notify the Trustee that any such assumption or substitution
agreement has been completed by forwarding to the Trustee (or the Custodian,
as the case may be) the original copy of such assumption or substitution
agreement (indicating the Mortgage File to which it relates) which copy shall
be added by the Trustee (or the Custodian, as the case may be) to the related
Mortgage File and which shall, for all purposes, be considered a part of such
Mortgage File to the same extent as all other documents and instruments
constituting a part thereof. The Servicer shall be responsible for recording
any such assumption or substitution agreements. In connection with any such
assumption or substitution agreement, the Monthly Payment on the related
Mortgage Loan shall not be changed but shall remain as in effect immediately
prior to the assumption or substitution, the stated maturity or outstanding
principal amount of such Mortgage Loan shall not be changed nor shall any
required monthly payments of principal or interest be deferred or forgiven.
Any fee collected by the Servicer for consenting to any such conveyance or
entering into an assumption or substitution agreement shall be retained by or
paid to the Servicer as additional servicing compensation.

            Notwithstanding the foregoing paragraph or any other provision of
this Agreement, the Servicer shall not be deemed to be in default, breach or
any other violation of its

                                     -75-
<PAGE>

obligations hereunder by reason of any assumption of a Mortgage Loan by
operation of law or any assumption which the Servicer may be restricted by law
from preventing, for any reason whatsoever.

            Section 3.15      Notification of Adjustments.

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

            Section 3.16      Optional Purchases of Mortgage Loans by
Servicer.

            The Servicer (or an Affiliate of the Servicer) may, at its option,
repurchase a Mortgage Loan or REO Property which becomes 120 or more days
Delinquent or for which the Servicer has accepted a deed in lieu of
foreclosure, during the period commencing on the first day of the calendar
quarter succeeding the calendar quarter in which the Initial Delinquency Date
occurred with respect to such Mortgage Loan and ending on the last Business
Day of such calendar quarter. If the Servicer (or an Affiliate of the
Servicer) does not exercise its purchase right with respect to a Mortgage Loan
during the period specified in the preceding sentence, such Mortgage Loan
shall thereafter again become eligible for purchase pursuant to the preceding
sentence only after the Mortgage Loan ceases to be 120 days or more Delinquent
and thereafter becomes 120 days Delinquent again. The "Initial Delinquency
Date" of a Mortgage Loan shall mean the date on which the Mortgage Loan first
became 120 days Delinquent. Prior to repurchase pursuant to this Section 3.16,
the Servicer shall be required to continue to make monthly advances pursuant
to Section 4.07. The Servicer shall not use any procedure in selecting
Mortgage Loans to be repurchased which is materially adverse to the interests
of the Certificateholders. The Servicer shall purchase such (i) Delinquent
Mortgage Loan at a price equal to the Principal Balance of the Mortgage Loan
plus accrued interest thereon at the Mortgage Interest Rate from the date to
which interest has last been paid to the Trust Fund to the date of purchase
plus any unreimbursed Servicing Advances and Advances or (ii) REO Property at
its fair market value as determined in good faith by the Servicer. Any such
repurchase of a Mortgage Loan or REO Property pursuant to this Section 3.16
shall be accomplished by delivery to the Trustee for deposit in the
Distribution Account of the amount of the purchase price. The Trustee shall
immediately effectuate the conveyance of such Delinquent Mortgage Loan or REO
Property to the Servicer to the extent necessary, including the prompt
delivery of all documentation to the Servicer.

            Section 3.17      Trustee to Cooperate; Release of Files.

            (a) Upon the payment in full of any Mortgage Loan (including any
liquidation of such Mortgage Loan through foreclosure or otherwise, or the
receipt by the Servicer of a notification that payment in full will be
escrowed in a manner customary for such purposes), the Servicer shall deliver
to the Trustee (or the Custodian as the case may be) two executed copies of a
completed "Request for Release" in the form of Exhibit E. Upon receipt of such
Request for Release of Documents, the Trustee (or the Custodian as the case
may be) shall promptly release the related Mortgage File, in trust to (i) the
Servicer, or (ii) such other party identified in the related Request for
Release. Upon any such payment in full, or the receipt of such notification
that such funds have been placed in escrow, the Servicer shall direct the
Trustee in writing to execute an instrument of satisfaction (or assignment of
Mortgage without recourse) regarding the Mortgaged Property relating to such
Mortgage, which instrument of satisfaction or assignment, as the case may be,
shall be delivered to the Person or Persons entitled thereto against receipt
therefor of payment in full, it being understood and agreed that no expense
incurred in connection with such instrument of satisfaction or assignment, as
the case may be, shall be chargeable to the Collection Account. In lieu of
executing any such satisfaction or assignment, as the case may be, the
Servicer may prepare and submit to the Trustee a satisfaction (or assignment
without recourse, if requested by the Person or Persons entitled thereto) in
form for execution by the Trustee with all requisite information completed by
the Servicer; in such event, the Trustee shall execute and acknowledge such
satisfaction or assignment, as the case may be, and deliver the same with the
related Mortgage File, as aforesaid.

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

            (c) Subject to Section 3.01, the Servicer shall have the right to
accept applications of Mortgagors for consent to (i) partial releases of
Mortgages, (ii) alterations, (iii) removal, demolition or division of
properties subject to Mortgages and (iv) second mortgage subordination
agreements. No application for approval shall be considered by the Servicer
unless: (w) it has received an Opinion of Counsel, addressed to the Trustee
(which opinion shall not be an expense of the Trustee or the Trust Fund) that
such sale, disposition, substitution, acquisition or contribution will not
affect adversely the status of any REMIC constituting part of the Trust Fund
as a REMIC or cause any REMIC constituting part of the Trust Fund to be
subject to a tax on "prohibited transactions" or "contributions" pursuant to
the REMIC

                                     -77-
<PAGE>

Provisions; (x) the provisions of the related Note and Mortgage have been
complied with; (y) the Combined Loan-to-Value Ratio and debt-to-income ratio
after any release does not exceed the maximum Combined Loan-to-Value Ratio and
debt-to-income ratio established in accordance with the underwriting standards
of the Mortgage Loans; and (z) the lien priority of the related Mortgage is
not affected. Upon receipt by the Trustee of a Servicing Officer's certificate
setting forth the action proposed to be taken in respect of a particular
Mortgage Loan and certifying that the criteria set forth in the immediately
preceding sentence have been satisfied, the Trustee shall execute and deliver
to the Servicer the consent or partial release so requested by the Servicer. A
proposed form of consent or partial release, as the case may be, shall
accompany any Servicing Officer's certificate delivered by the Servicer
pursuant to this paragraph.

            Section 3.18      Servicing Compensation.

            As compensation for its activities hereunder, the Servicer shall
be entitled to retain the amount of the Servicing Fee with respect to each
Mortgage Loan (including REO Properties). The Servicer shall be entitled to
retain additional servicing compensation in the form of release fees, bad
check charges, assumption fees, modification or extension fees, late payment
charges, customary real estate referral fees or any other service-related
fees, Insurance Proceeds and Liquidation Proceeds not required to be deposited
in the Collection Account and similar items, to the extent collected from
Mortgagors.

            Section 3.19      Annual Statement as to Compliance.

            (a) The Servicer, at its own expense, will deliver to the Trustee
and the Depositor, not later than March 15th of each calendar year commencing
in 2006, a Servicing Officer's certificate stating, as to each signer thereof,
that (i) a review of the activities of the Servicer during such preceding
calendar year (or such shorter period in the case of the first such report)
and of performance under this Agreement has been made under such officers'
supervision, and (ii) to the best of such officers' knowledge, based on such
review, the Servicer has fulfilled all its obligations under this Agreement
for such year, or, if there has been a default in the fulfillment of all such
obligations, specifying each such default known to such officers and the
nature and status thereof including the steps being taken by the Servicer to
remedy such default.

            (b) Delivery of such reports, information and documents to the
Trustee is for informational purposes only and their receipt of such shall not
constitute constructive notice of any information contained therein or
determinable, from information contained therein, including the Servicer's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

            Section 3.20      Annual Independent Certified Public Accountants'
Reports.

            (a) Not later than March 15th of each calendar year commencing in
2006, the Servicer, at its expense, shall cause a nationally recognized firm
of independent certified public accountants to furnish to the Trustee and the
Depositor a report stating that (i) it has obtained a letter of representation
regarding certain matters from the management of the Servicer which includes
an assertion that the Servicer has complied with certain minimum residential
mortgage loan servicing standards, identified in either the Uniform Single
Attestation Program for

                                     -78-
<PAGE>

Mortgage Bankers established by the Mortgage Bankers Association of America or
the Audit Program for Mortgages serviced by Freddie Mac, with respect to the
servicing of residential mortgage loans during the most recently completed
calendar year and (ii) on the basis of an examination conducted by such firm
in accordance with standards established by the American Institute of
Certified Public Accountants, such representation is fairly stated in all
material respects, subject to such exceptions and other qualifications that
may be appropriate. Immediately upon receipt of such report, the Servicer
shall furnish a copy of such report to the Trustee, the Depositor and each
Rating Agency. Copies of such statement shall be provided by the Trustee to
any Certificateholder upon request at the Servicer's expense, provided that
such statement is delivered by the Servicer to the Trustee.

            (b) Delivery of such reports, information and documents to the
Trustee is for informational purposes only and its receipt of such shall not
constitute constructive notice of any information contained therein or
determinable, from information contained therein, including the Servicer's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

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

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

            Section 3.22      Obligations of the Servicer in Respect of
Compensating Interest.

            Not later than the close of business on each Servicer Remittance
Date, the Servicer shall deliver to the Trustee for deposit in the
Distribution Account an amount ("Compensating Interest") equal to the lesser
of (A) the aggregate of the Prepayment Interest Shortfalls on the Mortgage
Loans for the related Distribution Date resulting from Principal Prepayments
on the Mortgage Loans during the related Prepayment Period and (B) 50% of its
aggregate Servicing Fee received in the related Collection Period. The
Servicer shall apply Compensating Interest to offset any Prepayment Interest
Shortfalls on the Mortgage Loans. The Servicer shall not have the right to
reimbursement for any amounts remitted to the Trustee for deposit in the
Distribution Account in respect of Compensating Interest. Such amounts so
remitted shall be included in the Available Funds and distributed therewith on
the next Distribution Date. The Servicer shall not be obligated to pay
Compensating Interest with respect to Relief Act Interest Shortfalls.

                                     -79-
<PAGE>

            Section 3.23      Obligations of the Servicer in Respect of
Mortgage Interest Rates and Monthly Payments.

            In the event that a shortfall in any collection on or liability
with respect to any Mortgage Loan results from or is attributable to
adjustments to Mortgage Interest Rates, Monthly Payments or Principal Balances
that were made by the Servicer in a manner not consistent with the terms of
the related Mortgage Note and this Agreement, the Servicer, upon discovery or
receipt of notice thereof, immediately shall deliver to the Trustee for
deposit in the Distribution Account from its own funds the amount of any such
shortfall and shall indemnify and hold harmless the Trust Fund, the Trustee,
the Depositor and any successor servicer in respect of any such liability.
Such indemnities shall survive the termination or discharge of this Agreement.

            Section 3.24      Obligations of the Servicer in Respect of Credit
Reporting.

            The Servicer will fully furnish, in accordance with the Fair
Credit Reporting Act and its implementing regulations, accurate and complete
information (i.e., favorable and unfavorable) on its borrower credit files to
Equifax, Experian, and Trans Union Credit Information Company (three of the
credit repositories), on a monthly basis for each Mortgage Loan.

            Section 3.25      Investment of Funds in the Collection Account
and the Distribution Account.

            (a) The Servicer may direct any depository institution maintaining
the Collection Account to invest the funds in the Collection Account in one or
more Permitted Investments bearing interest or sold at a discount, and
maturing, unless payable on demand, (i) no later than the Business Day
immediately preceding the date on which such funds are required to be
withdrawn from such account pursuant to this Agreement, if a Person other than
the Trustee is the obligor thereon, and (ii) no later than the date on which
such funds are required to be withdrawn from such account pursuant to this
Agreement, if the Trustee is the obligor thereon. In the absence of such
direction, funds in the Collection Account shall remain uninvested. Any such
Permitted Investments shall be held to maturity, unless payable on demand.
Funds in the Distribution Account shall be uninvested. Any investment of funds
in the Collection Account shall be made in the name of the Servicer. In the
event amounts on deposit in the Collection Account are at any time invested in
a Permitted Investment payable on demand, the Trustee shall at the direction
of the Servicer:

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

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

            (b) All income and gain realized from the investment of funds in
the Collection Account shall be for the benefit of the Servicer. The Servicer
shall deposit in the Collection Account the amount of any loss incurred in
respect of any such Permitted Investment made with funds in such account
immediately upon realization of such loss.

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

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

            Section 3.26      Liability of Servicer; Indemnification.

            (a) Subject to clause (b) below and Section 6.03, the Servicer
(except the Trustee if it is required to succeed the Servicer hereunder)
indemnifies and holds the Trustee, the Seller, the Depositor and each
Certificateholder harmless against any and all claims, losses, penalties,
fines, forfeitures, reasonable legal fees and related costs, judgments, and
any other costs, fees and expenses that the Trustee, the Depositor and any
Certificateholder may sustain in any way related to the failure of the
Servicer to perform its duties and service the Mortgage Loans in compliance
with the Servicing Standards. The Servicer shall immediately notify the
Trustee, the Depositor and each Certificateholder if a claim is made that may
result in such claims, losses, penalties, fines, forfeitures, legal fees or
related costs, judgments, or any other costs, fees and expenses, and the
Servicer shall assume (with the consent of the Trustee) the defense of any
such claim and pay all expenses in connection therewith, including reasonable
counsel fees, and promptly pay, discharge and satisfy any judgment or decree
which may be entered against the Servicer, the Trustee, the Depositor and/or
Certificateholder in respect of such claim. The provisions of this Section
3.26 shall survive the termination of this Agreement and the payment of the
outstanding Certificates.

            (b) None of the Depositor, the Seller, the Servicer, or any of the
directors, officers, employees or agents of the Depositor, the Seller or the
Servicer shall be under any liability to the Trust Fund or the
Certificateholders for any action taken, or for refraining from the taking of
any action, in good faith pursuant to this Agreement, or for errors in
judgment; provided, however, that this provision shall not protect the
Depositor, the Seller or the Servicer or any such Person against any breach of
warranties or representations made herein, or against any specific liability
imposed on the Servicer for a breach of the Servicing Standard, 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.

                                     -81-
<PAGE>

            The Depositor, the Servicer, the Seller and any director, officer,
employee or agent of the Depositor, the Seller or the Servicer, may rely in
good faith on any document of any kind which, prima facie, is properly
executed and submitted by any appropriate Person with respect to any matters
arising hereunder. The Depositor, the Servicer, the Seller, and any director,
officer, employee or agent of the Depositor, the Seller or the Servicer shall
be indemnified and held harmless by the Trust Fund against any loss, liability
or expense incurred in connection with any legal action relating to this
Agreement 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 hereunder or (in the case of the Servicer) a breach
of the Servicing Standard in the performance of its respective duties or by
reason of negligent disregard of its respective obligations or duties
hereunder. Neither the Depositor, the Seller nor the Servicer shall be under
any obligation to appear in, prosecute or defend any legal action unless such
action is related to its respective duties under this Agreement and in its
opinion does not expose it to any expense or liability; provided, however,
that the Depositor, the Seller or the Servicer may in its discretion undertake
any action related to its obligations hereunder which it may deem necessary or
desirable with respect to this Agreement and the rights and duties of the
parties hereto and the interests of the Certificateholders hereunder.

            Section 3.27      Reports of Foreclosure and Abandonment of
Mortgaged Properties.

            On or before the last day of February of each year beginning in
2005, the Servicer shall file the reports of foreclosure and abandonment of
any Mortgaged Property required by Section 6050J of the Code with the Internal
Revenue Service and provide an Officer's Certificate certifying its compliance
with this Section 3.27 to the Trustee. The reports from the Servicer shall be
in form and substance sufficient to meet the reporting requirements imposed by
such Section 6050J.

            Section 3.28      Protection of Assets.

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

            (1) borrow money or issue debt;

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

            (3) engage in any business or activities.

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

            Section 3.29      Periodic Filings.

            (a) The Trustee and the Servicer shall reasonably cooperate with
the Depositor in connection with satisfying the reporting requirements under
the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The
Trustee shall prepare and file (via the Securities and Exchange Commission's
Electronic Data Gathering and Retrieval System) on behalf of the Trust Fund
any Forms 8-K and 10-K (and the Servicer shall sign any 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. The
Depositor agrees to cooperate with the Trustee and Trustee's counsel to assist
the Trustee in determining the form and content of any filings that may be
required pursuant to this Section 3.29, and, without limiting the Trustee's
responsibility hereunder, otherwise to assist the Trustee in fulfilling its
duties under this Section 3.29.

            (b) Each Form 8-K shall be filed by the Trustee within 15 days
after each Distribution Date, with a copy of the statement to the
Certificateholders 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 Trustee shall file a Form 10-K, in substance as required by
applicable law or applicable Security and Exchange Commission staff's
interpretations. Such Form 10-K shall include as exhibits the Servicer's
annual statement of compliance described under Section 3.19 and the
accountant's report described under Section 3.20, in each case to the extent
they have been timely delivered to the Trustee. The Trustee shall have no
liability with respect to (i) any failure to properly prepare or file such
periodic reports resulting from or relating to the Trustee's inability or
failure to obtain any information not resulting from its own negligence,
willful misconduct or bad faith or (ii) any inaccuracy in such periodic
reports resulting from incorrect information provided to the Trustee by the
Servicer in a Remittance Report or otherwise. The Form 10-K shall also include
a certification in the form attached hereto as Exhibit V (the
"Certification"), which shall be signed by the senior officer of the Servicer
in charge of servicing.

            (c) In addition, the Trustee shall sign a certification (in the
form attached hereto as Exhibit W) for the benefit of the Servicer and its
officers, directors and Affiliates regarding certain aspects of the
Certification (the "Trustee Certification") (provided, however, that the
Trustee shall not undertake an analysis of the accountant's report attached as
an exhibit to the Form 10-K). Such certification shall be delivered to the
Servicer no later than the 20th day prior to the latest date on which the Form
10-K is permitted to be filed, without regard to extension (or if such day is
not a Business Day, the immediately preceding Business Day) and the Servicer
shall deliver the Certification to be filed to the Trustee no later than the
10th day prior to the latest date on which the Form 10-K is permitted to be
filed, without regard to extension (or if such day is not a Business Day, the
immediately preceding Business Day).

            In addition, (i) the Trustee shall, subject to the provisions of
Sections 8.01 and 8.02 hereof, indemnify and hold harmless the Depositor, the
Servicer and each of 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 (A) a breach of the Trustee's obligations under this
Section 3.29(b),

                                     -83-
<PAGE>

(B) the Trustee's negligence, bad faith or willful misconduct in connection
therewith or (C) any inaccuracy in the Trustee Certification and (ii) the
Servicer shall indemnify and hold harmless the Depositor, the Trustee and
their respective officers, directors and Affiliates from and against any
actual losses, damages, penalties, fines, forfeitures, reasonable and
necessary legal fees and related costs, judgments and other costs and expenses
arising out of or based upon (A) the failure of the Servicer to timely deliver
the Certification or (B) any material misstatement in the Certification. If
the indemnification provided for herein is unavailable or insufficient to hold
harmless the Depositor, then (i) the Trustee agrees that it shall contribute
to the amount paid or payable by the Depositor as a result of the losses,
claims, damages or liabilities of the Depositor in such proportion as is
appropriate to reflect the relative fault of the Depositor on the one hand and
the Trustee on the other in connection with a breach of the Trustee's
obligations under this Section 3.29(d) or the Trustee's negligence, bad faith
or willful misconduct in connection therewith and (ii) the Servicer agrees
that it shall contribute to the amount paid or payable by the Depositor as a
result of the losses, claims, damages or liabilities of the Depositor in such
proportion as is appropriate to reflect the relative fault of the Depositor on
the one hand and the Servicer on the other in connection with a breach of the
Servicer's obligations under this Section 3.29(c) or the Servicer's
negligence, bad faith or willful misconduct in connection therewith

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

            (e) Prior to January 30th of the first year in which the Trustee
is able to do so under applicable law, the Trustee shall file a Form 15
Suspension Notification with respect to the Trust Fund.

            (f) To the extent that, following the Closing Date, the Depositor
certifies that reports and certifications differing from those required under
this Section 3.29 comply with the reporting requirements under the Exchange
Act, the Trustee and the Servicer hereby agree that they will reasonably
cooperate to amend the provisions of this Section 3.29 in order to comply with
such amended reporting requirements and such amendment of this Section 3.29.
Any such amendment may result in the reduction of the reports filed by the
Depositor under the Exchange Act. Notwithstanding the foregoing, the parties
hereto shall not be obligated to enter into any amendment pursuant to this
Section 3.29 that adversely affects its obligations and immunities under this
Agreement.

            (d) If Subsequent Recoveries have been received with respect to a
Liquidated Mortgage Loan, the amount of such Subsequent Recoveries will be

not be entitled to any payment in respect of the Accrued Certificate Interest
on the amount of such increases for any Interest Accrual Period preceding the
Distribution Date on which such increase occurs. Any such increases shall be
applied pro rata to the Certificate Principal Balance of each Certificate of

Balance of the Class B-5, Class B-4, Class B-3, Class B-2, Class B-1, Class
M-3, Class M-2 and Class M-1 Certificates, in that order, until the respective
Certificate Principal Balances thereof are reduced to zero. Any reduction of a

to this paragraph (a) and paragraph (b) immediately below is an "Applied
Realized Loss Amount" for such Class.

            (b) Special Hazard Losses will be allocated as described above,
except that if the aggregate amount of such losses, as of any date of
determination, exceeds the greatest of (i) 1% of the Principal Balance of the
Mortgage Loans as of the Cut-off Date, (ii) two times the amount of the
Principal Balance of the largest Mortgage Loan as of the date of determination
and (iii) an amount equal to the current Principal Balances of the Mortgage
Loans in the largest zip-code concentration in the State of California as of
the date of determination, such excess losses will be allocated among all the
outstanding Classes of Certificates, pro rata, based on their respective
Certificate Principal Balances or Notional Amount, as applicable.

            The Trustee shall make distributions in respect of a Distribution
Date to each Certificateholder of record on the related Record Date (other
than as provided in Section 10.01 respecting the final distribution), in the
case of Certificateholders of the Certificates, by wire transfer in
immediately available funds to the account of the Person entitled thereto if
such Person shall have so notified the Trustee in writing at least five
Business Days prior to the Record Date immediately prior to such Distribution
Date and is the registered owner of such Certificates the aggregate initial
Certificate Principal Balance or Notional Amount of which is in excess of
$5,000,000, 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 Trustee may deduct a reasonable wire
transfer fee from any payment made by wire transfer. Distributions among
Certificateholders shall be made in proportion to the Percentage Interests
evidenced by the Certificates held by such Certificateholders.

but in no event less than four Business Days prior to the related Distribution
Date, the Servicer shall deliver to the Trustee by telecopy (or by such other
means as the Servicer and the Trustee may agree from time to time) a
Remittance Report with respect to the related Distribution Date. On the same
date, the Servicer shall forward to the Trustee by overnight mail a computer
readable magnetic tape or diskette or in such other medium as may be agreed
between the Servicer and the Trustee containing the information set forth in
such Remittance Report with respect to the related Distribution Date. Not
later than the close of business New York time on the Servicer Remittance
Date, the Servicer shall deliver or cause to be delivered to the Trustee in
addition to the information provided on the Remittance Report, such other
information reasonably available to it with respect to the Mortgage Loans as
the Trustee may reasonably request or order in order for the Trustee to
perform the calculations necessary to make the distributions contemplated by
Section 4.01, 4.02 and 4.03 and to prepare the statements to
Certificateholders contemplated by Section 4.06. The Trustee shall not be
responsible to recompute, recalculate or verify any information provided to it
by the Servicer.

            (b) The amount of Advances to be made by the Servicer for any
Distribution Date shall equal, subject to Section 4.07(d), (i) the aggregate
amount of Monthly Payments (net of the related Servicing Fee and other than
the portion of the Monthly Payment representing principal on any second lien
Mortgage Loan), due during the related Collection Period in respect of the
Actuarial Mortgage Loans, which Monthly Payments were delinquent on a
contractual basis as of the close of business on the related Determination
Date and (ii) with respect to each REO Property, which REO Property was
acquired during or prior to the related Prepayment Period and as to which such
REO Property an REO Disposition did not occur during the related Prepayment
Period, an amount equal to the excess, if any, of only the interest portion of
the Monthly Payments (net of the related Servicing Fee) that would have been
due on the related Due Date in respect of the related Mortgage Loans, over the
net income from such REO Property deposited in the Collection Account pursuant
to Section 3.13 for distribution on such Distribution Date. For purposes of
the preceding sentence, the Monthly Payment on each Balloon Mortgage Loan with
a delinquent Balloon Payment is equal to the assumed monthly payment that
would have been due on the related Due Date based on the original principal
amortization schedule for the such Balloon Mortgage Loan. The Servicer shall
not be obligated to make any Advance with respect to Simple Interest Mortgage
Loans.

            On or before the close of business New York time on the Servicer
Remittance Date, the Servicer shall remit in immediately available funds to
the Trustee for deposit in the Distribution Account an amount equal to the
aggregate amount of Advances, if any, to be made

                                     -96-
<PAGE>

in respect of the Mortgage Loans and REO Properties for the related
Distribution Date either (i) from its own funds or (ii) from the Collection
Account, to the extent of funds held therein for future distribution (in which
case it will cause to be made an appropriate entry in the records of the
Collection Account that amounts held for future distribution have been, as
permitted by this Section 4.07, used by the Servicer in discharge of any such
Advance) or (iii) in the form of any combination of (i) and (ii) aggregating
the total amount of Advances to be made by the Servicer with respect to the
Mortgage Loans and REO Properties. In addition, the Servicer shall have the
right to reimburse itself for any Advances previously made from the Collection
Account to the extent of funds held therein for future distribution pursuant
to Section 3.05(viii). Any amounts held for future distribution and so used
shall be appropriately reflected in the Servicer's records and replaced by the
Servicer by deposit in the Collection Account on or before any future Servicer
Remittance Date to the extent that the Available Funds for the related
Distribution Date (determined without regard to Advances to be made on the
Servicer Remittance Date) shall be less than the total amount that would be
distributed to the Classes of Certificateholders pursuant to Section 4.01 and
4.02 on such Distribution Date if such amounts held for future distributions
had not been so used to make Advances. The Trustee will provide notice to the
Servicer by telecopy by the close of business on any Servicer Remittance Date
in the event that the amount remitted by the Servicer to the Trustee on such
date is less than the Advances required to be made by the Servicer for the
related Distribution Date, as set forth in the related Remittance Report.

            (c) The obligation of the Servicer to make such Advances is
mandatory, notwithstanding any other provision of this Agreement but subject
to (d) below, and, with respect to any Mortgage Loan or REO Property, shall
continue until the earlier of such time as such Mortgage Loan is paid in full
by the Mortgagor or disposed of by the Trust, or until the recovery of all
Liquidation Proceeds thereon.

            (d) Notwithstanding anything herein to the contrary, no Advance or
Servicing Advance shall be required to be made hereunder by the Servicer if
such Advance would, if made, constitute a Nonrecoverable Advance. The
determination by the Servicer that it has made a Nonrecoverable Advance or
that any proposed Advance, if made, would constitute a Nonrecoverable Advance,
shall be evidenced by an Officers' Certificate of the Servicer delivered to
the Depositor and the Trustee.

            Section 4.08      Basis Risk Reserve Fund.

            (a) On the Closing Date, the Trustee shall establish and maintain
in its name, in trust for the benefit of the Holders of the Class AV
Certificates and the Subordinate Certificates Certificates, the Basis Risk
Reserve Fund. The Basis Risk Reserve Fund shall be an Eligible Account, and
funds on deposit therein shall be held separate and apart from, and shall not
be commingled with, any other moneys, including without limitation, other
moneys held by the Trustee pursuant to this Agreement.

            (b) On the Closing Date, $5,000 will be deposited by the Seller
into the Basis Risk Reserve Fund. On each Distribution Date, the Trustee shall
transfer from the Distribution Account to the Basis Risk Reserve Fund pursuant
to Section 4.02(b)(xxvi), the Basis Risk Reserve Fund Deposit. Following the
deposit of the Basis Risk Reserve Fund Deposit in the

                                     -97-
<PAGE>

Basis Risk Reserve Fund on such Distribution Date pursuant to Section
4.02(b)(xx) hereof, the Trustee shall withdraw any amounts on deposit in the
Basis Risk Reserve Fund in the following amounts and order of priority:

            (i) amounts attributable to Monthly Excess Cashflow Amounts in
      respect of Loan Group 1 to the Class AV Certificates any unpaid Net Rate
      Carryover Amounts for such Classes;

            (ii) to the Class M-1 Certificates, any unpaid Net Rate Carryover
      Amounts for such Class;

            (iii) to the Class M-2 Certificates, any unpaid Net Rate Carryover
      Amounts for such Class;

            (iv) to the Class M-3 Certificates, any unpaid Net Rate Carryover
      Amounts for such Class;

            (v) to the Class B-1 Certificates, any unpaid Net Rate Carryover
      Amounts for such Class;

            (vi) to the Class B-2 Certificates, any unpaid Net Rate Carryover
      Amounts for such Class;

            (vii) to the Class B-3 Certificates, any unpaid Net Rate Carryover
      Amounts for such Class.

            (viii) to the Class B-4 Certificates, any unpaid Net Rate
      Carryover Amounts for such Class; and

            (ix) to the Class B-5 Certificates, any unpaid Net Rate Carryover
      Amounts for such Class.

            Any such amounts distributed shall be treated for federal tax
purposes as amounts distributed by the Class X REMIC to the Class X Interest.
On any Distribution Date, any amounts on deposit in the Basis Risk Reserve
Fund in excess of the Required Basis Risk Reserve Fund Amount shall be
distributed first to the Class N Certificates and then to the Class X
Certificates in the same manner as if distributed pursuant to Sections
4.02(b)(xxvii) and (xxviii) hereof.

            (c) Funds in the Basis Risk Reserve Fund may be invested in
Eligible Investments by the Trustee at the direction of the majority holder of
the Class X Certificates. In the absence of such direction, funds in the Basis
Risk Reserve Fund shall remain uninvested. Any net investment earnings on such
amounts shall be payable to the Class X Certificates. Amounts held in the
Basis Risk Reserve Fund from time to time shall continue to constitute assets
of the Trust Fund, but not of any REMIC created hereunder, until released from
the Basis Risk Reserve Fund pursuant to this Section 4.08. The Basis Risk
Reserve Fund constitutes an "outside reserve fund" within the meaning of
Treasury Regulation ss.1.860G-2(h) and is not an asset of any REMIC created
hereunder. For all federal tax purposes, amounts transferred by the Class X
REMIC to

                                     -98-
<PAGE>

the Basis Risk Reserve Fund shall be treated as amounts distributed by the
Class X REMIC to the Class X Certificates. The Class X Certificates shall
evidence ownership of the Basis Risk Reserve Fund for federal tax purposes and
the Holders thereof shall direct the Trustee in writing as to the investment
of amounts therein. In the absence of such written direction, all funds in the
Basis Risk Reserve Fund shall remain uninvested. The Trustee shall have no
liability for losses on investments in Eligible Investments made pursuant to
this Section 4.08(c) (other than as obligor on any such investments). Upon
termination of the Trust Fund, any amounts remaining in the Basis Risk Reserve
Fund shall be distributed first to the Class N Certificates and then to the
Class X Certificates in the same manner as if distributed pursuant to Sections
4.02(b)(xxi) and (xxii) hereof.

            (d) On the Distribution Date immediately after the Distribution
Date on which the aggregate Class Principal Balance of each Class of
Certificates entitled to Net Rate Carryover Amounts equals zero, any amounts
on deposit in the Basis Risk Reserve Fund not payable on such Classes of
Certificates shall be distributed first to the Class N Certificates and then
to the Class X Certificates in the same manner as if distributed pursuant to
Sections 4.02(b)(xxvii) and (xxviii) hereof.

                                   ARTICLE V

                               THE CERTIFICATES

            Section 5.01      The Certificates.

            Each of the Certificates shall be substantially in the forms
annexed hereto as exhibits, and shall, on original issue, be executed by the
Trustee and authenticated and delivered by the Certificate Registrar to or
upon the receipt of a Written Order to Authenticate from the Depositor
concurrently with the sale and assignment to the Trustee of the Trust Fund.
Each Class of the Offered Certificates and the Class B-4 and Class B-5
Certificates shall be initially evidenced by one or more Certificates
representing a Percentage Interest with a minimum dollar (or notional amount)
denomination of $25,000 and integral multiples of $1.00 in excess thereof. The
Class N, Class X, Class R and Class XR Certificates are issuable only in
minimum Percentage Interests of 10%.

            The Certificates shall be executed on behalf of the Trust by
manual or facsimile signature on behalf of the Trustee by a Responsible
Officer. Certificates bearing the manual or facsimile signatures of
individuals who were, at the time when such signatures were affixed,
authorized to sign on behalf of the Trustee shall bind the Trust,
notwithstanding that such individuals or any of them have ceased to be so
authorized prior to the authentication and delivery of such Certificates or
did not hold such offices at the date of such Certificate. No Certificate
shall be entitled to any benefit under this Agreement or be valid for any
purpose, unless such Certificate shall have been manually authenticated by the
Certificate Registrar substantially in the form provided for herein, and such
authentication upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly authenticated and delivered
hereunder. All Certificates shall be dated the date of their authentication.
Subject to Section 5.02(c), the Offered Certificates and the Class B-4 and
Class B-5 Certificates shall be

                                     -99-
<PAGE>

Book-Entry Certificates. The Class N, Class X, Class R and Class XR
Certificates shall not be Book-Entry Certificates but shall be issued in fully
registered certificate form.

            Section 5.02      Registration of Transfer and Exchange of
Certificates.

            (a) The Certificate Registrar shall cause to be kept at the
Corporate Trust Office of the Trustee a Certificate Register in which, subject
to such reasonable regulations as it may prescribe, the Certificate Registrar
shall provide for the registration of Certificates and of transfers and
exchanges of Certificates as herein provided. The Trustee shall initially
serve as Certificate Registrar for the purpose of registering Certificates and
transfers and exchanges of Certificates as herein provided. The Trustee as
Certificate Registrar shall be subject to the same standards of care,
limitations on liability and rights to indemnity as the Trustee, and the
provisions of Sections 8.01, 8.02, 8.03, 8.04, 8.05, 8.14, 8.15 and 8.16 shall
apply to the Certificate Registrar to the same extent as they apply to the
Trustee. Any Certificate Registrar appointed in accordance with this Section
5.02(a) may at any time resign by giving at least 30 days' advance written
notice of resignation to the Trustee, the Servicer and the Depositor, such
resignation to become effective upon appointment of a successor Certificate
Registrar.

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

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

            (b) Upon original issuance, the Book-Entry Certificates shall be
issued in the form of one or more typewritten certificates, to be delivered to
the Depository, the initial Depository, by, or on behalf of, the Depositor; or
to, and deposited with the Custodian, on behalf of the Depository, if directed
to do so pursuant to instructions from the Depository. Except as provided in
paragraph (c) below, the Book-Entry Certificates shall at all times remain
registered in the name of the Depository or its nominee and at all times: (i)
registration of such Certificates may not be transferred by the Trustee except
to another Depository; (ii) the Depository shall maintain book-entry records
with respect to the Certificate Owners and with respect to ownership and
transfers of such Certificates; (iii) ownership and transfers of registration
of such Certificates on the books of the Depository shall be governed by
applicable rules established by the Depository; (iv) the Depository may
collect its usual and customary fees, charges and

                                    -100-
<PAGE>

expenses from its Depository Participants; (v) the Trustee shall for all
purposes deal with the Depository as representative of the Certificate Owners
of the Certificates for purposes of exercising the rights of Holders under
this Agreement, and requests and directions for and votes of such
representative shall not be deemed to be inconsistent if they are made with
respect to different Certificate Owners; (vi) the Trustee may rely and shall
be fully protected in relying upon information furnished by the Depository
with respect to its Depository Participants and furnished by the Depository
Participants with respect to indirect participating firms and Persons shown on
the books of such indirect participating firms as direct or indirect
Certificate Owners; and (vii) the direct participants of the Depository shall
have no rights under this Agreement under or with respect to any of the
Certificates held on their behalf by the Depository, and the Depository may be
treated by the Trustee and its agents, employees, officers and directors as
the absolute owner of the Certificates for all purposes whatsoever.

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

            (c) If (i)(x) the Depository or the Depositor advises the Trustee
in writing that the Depository is no longer willing or able to discharge
properly its responsibilities as Depository and (y) the Trustee or the
Depositor is unable to locate a qualified successor, (ii) the Depositor, at
its sole option, with the consent of the Trustee, elects to terminate the
book-entry system through the Depository or (iii) after the occurrence of a
Servicer Event of Termination, the Certificate Owners of each Class of
Book-Entry Certificates representing Percentage Interests of such Classes
aggregating not less than 51% advises the Trustee and Depository through the
Financial Intermediaries and the Depository Participants in writing that the
continuation of a book-entry system through the Depository to the exclusion of
definitive, fully registered certificates (the "Definitive Certificates") to
Certificate Owners is no longer in the best interests of the Certificate
Owners. Upon surrender to the Certificate Registrar of the Book-Entry
Certificates by the Depository, accompanied by registration instructions from
the Depository for registration, the Trustee shall, at the Depositor's
expense, in the case of (ii) above, or the Seller's expense, in the case of
(i) and (iii) above, execute on behalf of the Trust and the Certificate
Registrar shall authenticate the Definitive Certificates. None of the
Depositor or the Trustee shall be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be protected in relying
on, such instructions. Upon the issuance of Definitive Certificates, the
Trustee, the Certificate Registrar, the Servicer, any Paying Agent and the
Depositor shall recognize the Holders of the Definitive Certificates as
Certificateholders hereunder.

            (d) Except with respect to the initial transfer of the Private
Certificates by the Depositor, 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

                                    -101-
<PAGE>

accordance with the 1933 Act and laws. In the case of Private Certificates
that are not Book-Entry Certificates, in the event of any such transfer:(i)
unless such transfer is made to (x) a "qualified institutional buyer" (as
defined in Rule 144A) in reliance upon Rule 144A (as evidenced by the
applicable investment letter delivered to the Certificate Registrar, in
substantially the form attached hereto as Exhibit J) under the 1933 Act or (y)
an institutional investor that is an "accredited investor" (as defined in
Clauses (1), (2), (3) or (7) of Rule 501(a) of Regulation D under the Act) (as
evidenced by the applicable investment letter delivered to the Certificate
Registrar, in substantially the form attached hereto as Exhibit J), the
Certificate Registrar and the Depositor shall require a written Opinion of
Counsel (which may be in-house counsel) acceptable to and in form and
substance reasonably satisfactory to the Certificate Registrar and the
Depositor that such transfer may be made pursuant to an exemption, describing
the applicable exemption and the basis therefor, from the 1933 Act or is being
made pursuant to the 1933 Act, which Opinion of Counsel shall not be an
expense of the Certificate Registrar or the Depositor or (ii) the Certificate
Registrar shall require the transferor to execute a transferor certificate (in
substantially the form attached hereto as Exhibit L) and the transferee to
execute an investment letter (in substantially the form attached hereto as
Exhibit J) acceptable to and in form and substance reasonably satisfactory to
the Depositor and the Certificate Registrar certifying to the Depositor and
the Certificate Registrar the facts surrounding such transfer, which
investment letter shall not be an expense of the Certificate Registrar or the
Depositor. The Holder of a Private Certificate desiring to effect such
transfer shall, and does hereby agree to, indemnify the Certificate Registrar
and the Depositor against any liability that may result if the transfer is not
so exempt or is not made in accordance with such federal and state laws. In
the case of Private Certificates that are Book-Entry Certificates, each
Certificate Owner is required to be either (x) a "qualified institutional
buyer" (as defined in Rule 144A) in reliance upon Rule 144A under the 1933 Act
or (y) an institutional investor that is an "accredited investor" (as defined
in Clauses (1), (2), (3) or (7) of Rule 501(a) of Regulation D under the Act),
and each such Certificate Owner shall be deemed to make the representations,
warranties and covenants in the applicable investment letter attached hereto
as Exhibit J.

            No transfer of an ERISA-Restricted Certificate shall be made
unless the Certificate Registrar shall have received either (i) a
representation from the transferee of such Certificate, acceptable to and in
form and substance satisfactory to the Servicer, the Certificate Registrar and
the Depositor (such requirement is satisfied only by the Certificate
Registrar's receipt of a representation letter from the transferee
substantially in the form of Exhibit I hereto, as appropriate), to the effect
that such transferee is not an employee benefit plan or arrangement subject to
Section 406 of ERISA or a plan or arrangement subject to Section 4975 of the
Code, nor a person acting on behalf of any such plan or arrangement or using
the assets of any such plan or arrangement to effect such transfer or (ii)
(except in the case of a Class R, Class XR or Class X Certificate) if the
purchaser is an insurance company, a representation that the purchaser is an
insurance company which is purchasing such Certificates with funds contained
in an "insurance company general account" (as such term is defined in Section
V(e) of Prohibited Transaction Class Exemption 95-60 ("PTCE 95-60") and that
the purchase and holding of such Certificates satisfy the requirements for
exemptive relief under Sections I and III of PTCE 95-60 or (iii) in the case
of any ERISA-Restricted Certificate presented for registration in the name of
an employee benefit plan or arrangement 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 or any other person acting on behalf
of any such plan or arrangement or using such plan's or

                                    -102-
<PAGE>

arrangement's assets, an Opinion of Counsel satisfactory to the Servicer, the
Certificate Registrar and the Depositor (which Opinion of Counsel shall not be
an expense of the Servicer, the Certificate Registrar, the Depositor or the
Trust), and upon which the Trustee, the Depositor, the Servicer and the
Certificate Registrar shall be entitled to rely, to the effect that the
purchase and holding of such ERISA-Restricted Certificate will not result in a
non-exempt prohibited transaction under ERISA or Section 4975 of the Code and
will not subject the Trustee, the Depositor or the Servicer to any obligation
in addition to those expressly undertaken in this Agreement or to any
liability. For purposes of clauses (i) and (ii) of the preceding sentence, one
of such representations shall be deemed to have been made to the Certificate
Registrar by the acceptance by a Certificate Owner of the beneficial interest
in any Class of ERISA-Restricted Certificates, unless the Certificate
Registrar shall have received from the transferee an alternative
representation or opinion acceptable in form and substance to the Servicer,
the Certificate Registrar and the Depositor. Notwithstanding anything else to
the contrary herein, any purported transfer of an ERISA-Restricted Certificate
to or on behalf of an employee benefit plan or arrangement subject to ERISA or
to the Code in violation of this paragraph, as described above, shall be void
and of no effect.

            Each Person who has or who acquires any Ownership Interest in a
Residual Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the following provisions and
to have irrevocably 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 a Residual Certificate are expressly
subject to the following provisions:

            (i) Each Person holding or acquiring any Ownership Interest in a
      Residual 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 a Residual
      Certificate unless such Ownership Interest is a pro rata undivided
      interest.

            (iii) In connection with any proposed transfer of any Ownership
      Interest in a Class R Certificate, the 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 Residual 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 Residual Certificates.

                                    -103-
<PAGE>

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

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

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

            The foregoing provisions of this Section shall cease to apply to
transfers occurring on or after the date on which there shall have been
delivered to the Certificate Registrar, in form and substance satisfactory to
the Certificate Registrar, (i) written notification from each Rating Agency
that the removal of the restrictions on Transfer set forth in this Section
will not cause

                                    -104-
<PAGE>

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
hereunder to fail to qualify as a REMIC.

            The beneficial ownership of the Class N Certificates and the Class
X Certificates shall not be transferred to a non-United States Person unless
such beneficial ownership is transferred to a non-United States Person who
will at all times be a Proportionate Holder. Neither the Class N nor the Class
X Certificates shall be pledged or used as collateral for any other obligation
if it would cause any portion of the Trust Fund to be treated as a taxable
mortgage pool under section 7701(i) of the Code. These restrictions on
transfers of Class X and Class N Certificates set forth in this Section 5.02
shall cease to apply (and the applicable portions of any legend on a Class X
or Class N Certificate may be deleted) with respect to transfers occurring
after delivery to the Trustee of an Opinion of Counsel, which Opinion of
Counsel shall not be an expense of the Trustee, the Seller or the Master
Servicer to the effect that the elimination of such restrictions will not
cause the Trust Fund to fail to qualify as a REMIC at any time that the
Certificates are outstanding or result in the imposition of any tax or tax
reporting obligation on the Trust Fund, a Certificateholder or another Person.

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

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

            Section 5.03      Mutilated, Destroyed, Lost or Stolen
Certificates.

            If (i) any mutilated Certificate is surrendered to the Certificate
Registrar or the Certificate Registrar receives evidence to its satisfaction
of the destruction, loss or theft of any Certificate and (ii) there is
delivered to the Trustee, the Depositor and the Certificate Registrar such
security or indemnity as may be required by them to save each of them
harmless, then, in the absence of notice to the Trustee or the Certificate
Registrar that such Certificate has been acquired by a bona fide purchaser,
the Trustee shall execute on behalf of the Trust, and the Certificate
Registrar shall authenticate and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Certificate, a new Certificate of
like tenor and Percentage Interest. Upon the issuance of any new Certificate
under this Section, the Trustee or the Certificate Registrar may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses (including the fees
and expenses of the Trustee and the Certificate Registrar) in connection
therewith. Any duplicate Certificate issued pursuant to this Section, shall
constitute complete and indefeasible evidence of ownership in the Trust, as if
originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

            Section 5.04      Persons Deemed Owners.

            The Servicer, the Depositor, the Trustee, the Certificate
Registrar, any Paying Agent and any agent of the Servicer, the Depositor, the
Certificate Registrar, any Paying Agent

                                    -105-

or the Trustee may treat the Person, including a Depository, in whose name any
Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions pursuant to Section 4.01 and 4.02 and for all other
purposes whatsoever, and none of the Servicer, the Trust, the Trustee nor any
agent of any of them shall be affected by notice to the contrary.

            Section 5.05      Appointment of Paying Agent.

            The Paying Agent shall make distributions to Certificateholders
from the Distribution Account pursuant to Sections 4.01 and 4.02 and shall
report the amounts of such distributions to the Trustee. The duties of the
Paying Agent may include the obligation (i) to withdraw funds from the
Collection Account pursuant to Section 3.05 and for the purpose of making the
distributions referred to above and (ii) to distribute statements and provide
information to Certificateholders as required hereunder. The Paying Agent
hereunder shall at all times be an entity duly incorporated and validly
existing under the laws of the United States of America or any state thereof,
authorized under such laws to exercise corporate trust powers and subject to
supervision or examination by federal or state authorities. The Paying Agent
shall initially be the Trustee. The Trustee may appoint a successor to act as
Paying Agent, which appointment shall be reasonably satisfactory to the
Depositor and the Rating Agencies. The Trustee as Paying Agent shall be
subject to the same standards of care, limitations on liability and rights to
indemnity as the Trustee, and the provisions of Sections 8.01, 8.02, 8.03,
8.04, 8.05, 8.14, 8.15 and 8.16 shall apply to the Paying Agent to the same
extent as they apply to the Trustee. Any Paying Agent appointed in accordance
with this Section 5.02(a) may at any time resign by giving at least 30 days'
advance written notice of resignation to the Trustee, the Servicer and the
Depositor, such resignation to become effective upon appointment of a
successor Paying Agent.

                  THE SELLER, THE SERVICER AND THE DEPOSITOR

            Section 6.01      Liability of the Seller, the Servicer and the
Depositor.

            The Seller and the Servicer shall be liable in accordance herewith
only to the extent of the obligations specifically imposed upon and undertaken
by the Seller or Servicer, as the case may be, 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 Seller, the Servicer or the Depositor.

            Any entity into which the Seller, the Servicer or the Depositor
may be merged or consolidated, or any entity resulting from any merger,
conversion or consolidation to which the Seller, the Servicer or the Depositor
shall be a party, or any corporation succeeding to the business of the Seller,
the Servicer or the Depositor, shall be the successor of the Seller, the
Servicer or the Depositor, as the case may be, hereunder, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, anything herein to the contrary

                                    -106-

notwithstanding; provided, however that the successor Servicer shall satisfy
all the requirements of Section 7.02 with respect to the qualifications of a
successor Servicer.

            Section 6.03      Limitation on Liability of the Servicer and
Others.

            Neither the Servicer nor any of the directors or officers or
employees or agents of the Servicer shall be under any liability to the Trust
or the Certificateholders for any action taken or for refraining from the
taking of any action by the Servicer in good faith pursuant to this Agreement,
or for errors in judgment; provided, however, that this provision shall not
protect the Servicer or any such Person against any liability which would
otherwise be imposed by reason of its willful misfeasance, bad faith or gross
negligence in the performance of duties of the Servicer or by reason of its
reckless disregard of its obligations and duties of the Servicer hereunder;
provided, further, that this provision shall not be construed to entitle the
Servicer to indemnity in the event that amounts advanced by the Servicer to
retire any senior lien exceed Liquidation Proceeds (in excess of related
liquidation expenses) realized with respect to the related Mortgage Loan. The
Servicer and any director or officer or employee or agent of the Servicer may
rely in good faith on any document of any kind prima facie properly executed
and submitted by any Person respecting any matters arising hereunder. The
Servicer and any director or officer or employee or agent of the Servicer
shall be indemnified by the Trust and held harmless against any loss,
liability or expense incurred in connection with any legal action relating to
this Agreement or the Certificates, other than any loss, liability or expense
incurred by reason of its willful misfeasance, bad faith or negligence in the
performance of duties hereunder or by reason of its reckless disregard of
obligations and duties hereunder. The Servicer may undertake any such action
which it may deem necessary or desirable in respect of this Agreement, and the
rights and duties of the parties hereto and the interests of the
Certificateholders hereunder. In such event, the reasonable legal expenses and
costs of such action and any liability resulting therefrom shall be expenses,
costs and liabilities of the Trust and the Servicer shall be entitled to pay
such expenses from the proceeds of the Trust or to be reimbursed therefor
pursuant to Section 3.05 upon presentation to the Trustee of documentation of
such expenses, costs and liabilities. The Servicer's right to indemnity or
reimbursement pursuant to this Section shall survive any resignation or
termination of the Servicer pursuant to Section 6.04 or 7.01 with respect to
any losses, expenses, costs or liabilities arising prior to such resignation
or termination (or arising from events that occurred prior to such resignation
or termination). This paragraph shall apply to the Servicer solely in its
capacity as Servicer hereunder and in no other capacities.

            Section 6.04      Servicer Not to Resign.

            Subject to the provisions of Section 7.01 and Section 6.02, the
Servicer shall not resign from the obligations and duties hereby imposed on it
except (i) upon determination that the performance of its obligations or
duties hereunder are no longer permissible under applicable law or are in
material conflict by reason of applicable law with any other activities
carried on by it or its subsidiaries or Affiliates, the other activities of
the Servicer so causing such a conflict being of a type and nature carried on
by the Servicer or its subsidiaries or Affiliates at the date of this
Agreement or (ii) upon satisfaction of the following conditions: (a) the
Servicer has proposed a successor servicer to the Trustee in writing and such
proposed successor servicer is reasonably acceptable to the Trustee; and (b)
each Rating Agency shall have delivered a letter to the Trustee prior to the
appointment of the successor servicer stating that the proposed

                                    -107-
<PAGE>

appointment of such successor servicer as Servicer hereunder will not result
in the reduction or withdrawal of the then current rating of the Regular
Certificates or the ratings that are in effect; provided, however, that no
such resignation by the Servicer shall become effective until such successor
servicer or, in the case of (i) above, the Trustee shall have assumed the
Servicer's responsibilities and obligations hereunder or the Trustee shall
have designated a successor servicer in accordance with Section 7.02. Any such
resignation shall not relieve the Servicer of responsibility for any of the
obligations specified in Sections 7.01 and 7.02 as obligations that survive
the resignation or termination of the Servicer. Any such determination
permitting the resignation of the Servicer pursuant to clause (i) above shall
be evidenced by an Opinion of Counsel to such effect delivered to the Trustee.
Any such determination permitting the resignation of the Servicer shall be
evidenced by an Opinion of Counsel to such effect delivered to the Trustee.

            The Trustee and the Depositor hereby specifically (i) consent to
the pledge and assignment by the Servicer of all the Servicer's right, title
and interest in, to and under this Agreement to the Servicing Rights Pledgee,
for the benefit of certain lenders, and (ii) provided that no Servicer Event
of Termination exists, agree that upon delivery to the Trustee by the
Servicing Rights Pledgee of a letter signed by the Servicer whereunder the
Servicer shall resign as Servicer under this Agreement, the Trustee shall
appoint the Servicing Rights Pledgee or its designee as successor Servicer,
provided that at the time of such appointment, the Servicing Rights Pledgee or
such designee meets the requirements of a successor Servicer pursuant to
Section 7.02(a) and agrees to be subject to the terms of this Agreement. If,
pursuant to any provision hereof, the duties of the Servicer are transferred
to a successor, the entire amount of the Servicing Fee and other compensation
payable to the Servicer pursuant hereto shall thereafter be payable to such
successor.

            Section 6.05      Delegation of Duties.

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

            (b) The Servicer is hereby authorized to enter into a financing or
other facility (any such arrangement, an "Advance Facility"), the
documentation for which complies with Section 6.05(d) below, under which (1)
the Servicer assigns or pledges its rights under this Agreement to be
reimbursed for any or all Advances and/or Servicing Advances to (i) a Person,
which may be a special-purpose bankruptcy-remote entity (an "SPV"), (ii) a
Person, which may simultaneously assign or pledge such rights to an SPV or
(iii) a lender (a "Lender"), which, in the case of any Person or SPV of the
type described in either of the preceding clauses (i) or (ii), may directly or
through other assignees and/or pledgees, assign or pledge such rights to a
Person, which may include a trustee acting on behalf of holders of debt
instruments (any such Person or any such Lender, an "Advance Financing
Person"), and/or (2) an Advance Financing Person

                                    -108-
<PAGE>

agrees to fund all the Advances and/or Servicing Advances required to be made
by the Servicer pursuant to this Agreement. No consent of the Trustee,
Certificateholders or any other party shall be required before the Servicer
may enter into an Advance Facility nor shall the Trustee or the
Certificateholders be a third party beneficiary of any obligation of an
Advance Financing Person to the Servicer. Notwithstanding the existence of any
Advance Facility under which an Advance Financing Person agrees to fund
Advances and/or Servicing Advances, (A) the Servicer (i) shall remain
obligated pursuant to this Agreement to make Advances and/or Servicing
Advances pursuant to and as required by this Agreement and (ii) shall not be
relieved of such obligations by virtue of such Advance Facility and (B)
neither the Advance Financing Person nor any Servicer's Assignee (as
hereinafter defined) shall have any right to proceed against or otherwise
contact any Mortgagor for the purpose of collecting any payment that may be
due with respect to any related Mortgage Loan or enforcing any covenant of
such Mortgagor under the related Mortgage Loan documents.

            (c) If the Servicer enters into an Advance Facility, the Servicer
and the related Advance Financing Person shall deliver to the Trustee at the
address set forth in Section 11.05 hereof a written notice (an "Advance
Facility Notice"), stating (a) the identity of the Advance Financing Person
and (b) the identity of the Person (the "Servicer's Assignee") that will,
subject to Section 6.05(d) hereof, have the right to make withdrawals from the
Collection Account pursuant to Section 3.05 hereof to reimburse previously
unreimbursed Advances and/or Servicing Advances ("Advance Reimbursement
Amounts"). Advance Reimbursement Amounts (i) shall consist solely of amounts
in respect of Advances and/or Servicing Advances for which the Servicer would
be permitted to reimburse itself in accordance with Section 3.05 hereof,
assuming the Servicer had made the related Advance(s) and/or Servicing
Advance(s) and (ii) shall not consist of amounts payable to a successor
Servicer in accordance with Section 3.05 hereof to the extent permitted under
Section 6.05(e) below.

            (d) Notwithstanding the existence of an Advance Facility, the
Servicer, on behalf of the Advance Financing Person and the Servicer's
Assignee, shall be entitled to receive reimbursements of Advances and/or
Servicing Advances in accordance with Section 3.05 hereof, which entitlement
may be terminated by the Advance Financing Person pursuant to a written notice
to the Trustee in the manner set forth in Section 11.05 hereof. Upon receipt
of such written notice, the Servicer shall no longer be entitled to receive
reimbursement for any Advance Reimbursement Amounts and the Servicer's
Assignee shall immediately have the right to receive from the Collection
Account all Advance Reimbursement Amounts. Notwithstanding the foregoing, and
for the avoidance of doubt, (i) the Servicer and/or the Servicer's Assignee
shall only be entitled to reimbursement of Advance Reimbursement Amounts
hereunder pursuant to Section 3.05 of this Agreement and shall not otherwise
be entitled to make withdrawals of or receive Advance Reimbursement Amounts
that shall be deposited in the Distribution Account pursuant to Section
3.04(b) hereof and (ii) none of the Trustee or the Certificateholders shall
have any right to, or otherwise be entitled to, receive any Advance
Reimbursement Amounts to which the Servicer or Servicer's Assignee, as
applicable, shall be entitled pursuant to Section 6.05 hereof. An Advance
Facility may be terminated by the joint written direction of the Servicer and
the related Advance Financing Person. Written notice of such termination shall
be delivered to the Trustee in the manner set forth in Section 11.05 hereof.
The Trustee shall have no duty or liability with respect to the calculation of
any Advance Reimbursement Amount and shall be entitled to rely without
independent investigation on the Advance Facility Notice and on

                                    -109-
<PAGE>

such Servicer's report of the amount of Advance Reimbursement Amounts and
Servicing Advance Reimbursement Amounts that were included in the remittance
from such Servicer to the Trustee pursuant to Section 4.07. Such Servicer
shall maintain and provide to any successor Servicer a detailed accounting on
a loan-by-loan basis as to amounts advanced by, pledged or assigned to, and
reimbursed to any Advance Financing Person. The successor Servicer shall be
entitled to rely on any such information provided by the predecessor Servicer,
and the successor Servicer shall not be liable for any errors in such
information.

            (e) As between a predecessor Servicer and its Advance Financing
Person, on the one hand, and a successor Servicer and its Advance Financing
Person, if any, on the other hand, Advance Reimbursement Amounts on a
loan-by-loan basis with respect to each Mortgage Loan as to which an Advance
and/or Servicing Advance shall have been made and be outstanding shall be
allocated on a "first-in, first out" basis. In the event the Servicer's
Assignee shall have received some or all of an Advance Reimbursement Amount
related to Advances and/or Servicing Advances that were made by a Person other
than such predecessor Servicer or its related Advance Financing Person in
error, then such Servicer's Assignee shall be required to remit any portion of
such Advance Reimbursement Amount to each Person entitled to such portion of
such Advance Reimbursement Amount. Without limiting the generality of the
foregoing, the Servicer shall remain entitled to be reimbursed by the Advance
Financing Person for all Advances and/or Servicing Advances funded by the
Servicer to the extent the related Advance Reimbursement Amounts have not been
assigned or pledged to such Advance Financing Person or Servicer's Assignee.

            (f) For purposes of any Officer's Certificate of the Servicer made
pursuant to Section 4.07(d), any Nonrecoverable Advance referred to therein
may have been made by such Servicer or any predecessor Servicer. In making its
determination that any Advance or Servicing Advance theretofore made has
become a Nonrecoverable Advance, the Servicer shall apply the same criteria in
making such determination regardless of whether such Advance or Servicing
Advance shall have been made by the Servicer or any predecessor Servicer.

            (g) The Trustee shall not, as a result of the existence of any
Advance Facility, have any additional responsibility to track or monitor
Advance Reimbursement Amounts or any Advance Facility, and, except as
expressly provided in Section 6.05(c) above, is not and shall not be obligated
to make any payment with respect to any Advance Reimbursement Amount. The
Servicer hereby indemnifies the Trustee, the Trust Fund and any successor
Servicer, as applicable, from and against any claims, losses, liabilities or
damages resulting from any claim by the related Advancing Person, except to
the extent that such claim, loss, liability or damage resulted from or arose
out of negligence, recklessness or willful misconduct on the part of the
Trustee or the successor Servicer, or failure by the successor Servicer or the
Trustee to remit funds as required by this Agreement or the commission of an
act or omission to act by the successor Servicer or the Trustee, and the
passage of any applicable cure or grace period, such that a Servicer Event of
Termination under this Agreement occurs or such entity is subject to
termination for cause under this Agreement.

      or Distribution Account any deposit required to be made under the terms
      of this Agreement which continues unremedied for a period of one
      Business Day after the date upon which written notice of such failure
      shall have been given to the Servicer by the Trustee or by any Holder of
      a Regular Certificate evidencing at least 25% of the Voting Rights; or

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

            (iii) The entry against the Servicer of a decree or order by a
      court or agency or supervisory authority having jurisdiction in the
      premises for the appointment of a trustee, conservator, receiver or
      liquidator in any insolvency, conservatorship, receivership,
      readjustment of debt, marshalling of assets and liabilities or similar

      the continuance of any such decree or order unstayed and in effect for a

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

            (v) The aggregate amount of cumulative Realized Losses incurred
      since the Cut-off Date through the last day of the related Collection
      Period divided by the initial Pool Balance exceeds the applicable
      percentages set forth below with respect to such Distribution Date:

           Distribution Date Occurring In                 Percentage

           February 2008 through January 2009                4.00%
           February 2009 through January 2010                5.85%
           February 2010 through January 2011                7.65%
           February 2011 through January 2012                8.60%
           February 2012 and thereafter                      9.00%

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

                                    -112-
<PAGE>

predecessor Servicer (or if the predecessor Servicer is the Trustee, the
initial Servicer) upon presentation of reasonable documentation of such costs
and expenses.

            Section 7.02      Trustee to Act; Appointment of Successor.

            (a) Within 90 days of the time the Servicer and the Trustee
receives a notice of termination pursuant to Section 7.01 or 6.04, the Trustee
(or such other successor Servicer as is approved in accordance with this
Agreement) shall be the successor in all respects to the Servicer in its
capacity as servicer under this Agreement and the transactions set forth or
provided for herein and shall be subject to all the responsibilities, duties
and liabilities relating thereto placed on the Servicer by the terms and
provisions hereof arising on and after its succession. As compensation
therefor, the Trustee (or such other successor Servicer) shall be entitled to
such compensation as the Servicer would have been entitled to hereunder if no
such notice of termination had been given. Notwithstanding the above, (i) if
the Trustee is unwilling to act as successor Servicer or (ii) if the Trustee
is legally unable so to act, the Trustee shall appoint or petition a court of
competent jurisdiction to appoint, any established housing and home finance
institution, bank or other mortgage loan or home equity loan servicer having a
net worth of not less than $50,000,000 as the successor to the Servicer
hereunder in the assumption of all or any part of the responsibilities, duties
or liabilities of the Servicer hereunder; provided, however, that the
appointment of any such successor Servicer will not result in the
qualification, reduction or withdrawal of the ratings assigned to the
Certificates or the ratings that are in effect by the Rating Agencies as
evidenced by a letter to such effect from the Rating Agencies. Pending
appointment of a successor to the Servicer hereunder, unless the Trustee is
prohibited by law from so acting, the Trustee shall act in such capacity as
hereinabove provided. In connection with such appointment and assumption, the
successor shall be entitled to receive compensation out of payments on
Mortgage Loans in an amount equal to the compensation which the Servicer would
otherwise have received pursuant to Section 3.18 (or such other compensation
as the Trustee and such successor shall agree, not to exceed the Servicing
Fee). The successor servicer shall be entitled to withdraw from the Collection
Account all costs and expenses associated with the transfer of the servicing
to the successor servicer. The appointment of a successor servicer shall not
affect any liability of the predecessor Servicer which may have arisen under
this Agreement prior to its termination as Servicer to pay any deductible
under an insurance policy pursuant to Section 3.12 or to indemnify the parties
indicated in Section 3.26 pursuant to the terms thereof, nor shall any
successor Servicer be liable for any acts or omissions of the predecessor
Servicer or for any breach by such Servicer of any of its representations or
warranties contained herein or in any related document or agreement. The
Trustee and such successor shall take such action, consistent with this
Agreement, as shall be necessary to effectuate any such succession.

            In the event of a Servicer Event of Termination, notwithstanding
anything to the contrary above, the Trustee and the Depositor hereby agree
that upon delivery to the Trustee by the Servicing Rights Pledgee of a letter
signed by the Servicer within ten Business Days of when notification of such
event shall have been provided to the Trustee, whereunder the Servicer shall
resign as Servicer under this Agreement, the Servicing Rights Pledgee or its
designee shall be appointed as successor Servicer (provided that at the time
of such appointment the Servicing Rights Pledgee or such designee meets the
requirements of a successor Servicer set forth above) and the Servicing Rights
Pledgee agrees to be subject to the terms of this Agreement.

                                    -113-
<PAGE>

            (b) Any successor, including the Trustee, to the Servicer as
servicer shall during the term of its service as servicer continue to service
and administer the Mortgage Loans for the benefit of Certificateholders, and
maintain in force a policy or policies of insurance covering errors and
omissions in the performance of its obligations as Servicer hereunder and a
Fidelity Bond in respect of its officers, employees and agents to the same
extent as the Servicer is so required pursuant to Section 3.12.

            Section 7.03      Waiver of Defaults.

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

            Section 7.04      Notification to Certificateholders.

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

            (b) No later than 60 days after the occurrence of any event which
constitutes or which, with notice or a lapse of time or both, would constitute
a Servicer Event of Termination for five Business Days after a Responsible
Officer of the Trustee becomes aware of the occurrence of such an event, the
Trustee shall transmit by mail to all Certificateholders notice of such
occurrence unless such default or Servicer Event of Termination shall have
been waived or cured. Such notice shall be given to the Rating Agencies
promptly after any such occurrence.

            Section 7.05      Survivability of Servicer Liabilities.

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

                                 ARTICLE VIII

                                  THE TRUSTEE

            Section 8.01      Duties of Trustee.

            The Trustee, prior to the occurrence of a Servicer Event of
Termination of which a Responsible Officer of the Trustee shall have actual
knowledge and after the curing of all Servicer Events of Termination which may
have occurred, undertakes to perform such duties and

                                    -114-
<PAGE>

only such duties as are specifically set forth in this Agreement. If a
Servicer Event of Termination has occurred (which has not been cured) of which
a Responsible Officer has actual knowledge, the Trustee shall exercise such of
the rights and powers vested in it by this Agreement, and use the same degree
of care and skill in their exercise, as a prudent person would exercise or use
under the circumstances in the conduct of such person's own affairs.

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

            No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own misconduct; provided, however, that:

            (i) prior to the occurrence of a Servicer Event of Termination,
      and after the curing of all such Servicer Events of Termination which
      may have occurred, the duties and obligations of the Trustee shall be
      determined solely by the express provisions of this Agreement, the
      Trustee shall not be liable except for the performance of such duties
      and obligations as are specifically set forth in this Agreement, no
      implied covenants or obligations shall be read into this Agreement
      against the Trustee and, in the absence of bad faith on the part of the
      Trustee, the Trustee may conclusively rely, as to the truth of the
      statements and the correctness of the opinions expressed therein, upon
      any certificates or opinions furnished to the Trustee and conforming to
      the requirements of this Agreement;

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

            (iii) the Trustee shall not be liable with respect to any action
      taken, suffered or omitted to be taken by it in good faith in accordance
      with the direction of the Majority Certificateholders relating to the
      time, method and place of conducting any proceeding for any remedy
      available to the Trustee or exercising or omitting to exercise any trust
      or power conferred upon the Trustee under this Agreement; and

            (iv) the Trustee shall not be charged with knowledge of any
      failure by the Servicer to comply with the obligations of the Servicer
      referred to in clauses (i) and (ii) of Section 7.01(a) or any Servicer
      Event of Termination unless a Responsible Officer of the Trustee at the
      applicable Corporate Trust Office obtains actual knowledge of such
      failure or the Trustee receives written notice of such failure from the
      Servicer or the Majority

                                    -115-
<PAGE>

      Certificateholders. In the absence of such receipt of such notice, the
      Trustee may conclusively assume that there is no Servicer Event of
      Termination.

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

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

            Section 8.02      Certain Matters Affecting the Trustee.

            (a) Except as otherwise provided in Section 8.01:

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

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

            (iii) the Trustee shall not be under any obligation to exercise
      any of the rights or powers vested in it by this Agreement, or to
      institute, conduct or defend any litigation hereunder or in relation
      hereto, at the request, order or direction of the Certificateholders
      pursuant to the provisions of this Agreement, unless such
      Certificateholders shall have offered to the Trustee reasonable security
      or indemnity against the costs, expenses and liabilities which may be
      incurred therein or thereby; the right of the Trustee to perform any
      discretionary act enumerated in this Agreement shall not be construed as
      a duty, and the Trustee shall not be answerable for other than its
      negligence or willful misconduct in the performance of any such act;

                                    -116-
<PAGE>

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

            (v) prior to the occurrence of a Servicer Event of Termination and
      after the curing of all Servicer Events of Termination which may have
      occurred, the Trustee shall not be bound to make any investigation into
      the facts or matters stated in any resolution, certificate, statement,
      instrument, opinion, report, notice, request, consent, order, approval,
      bond or other paper or documents, unless requested in writing to do so
      by the Majority Certificateholder; provided, however, that if the
      payment within a reasonable time to the Trustee of the costs, expenses
      or liabilities likely to be incurred by it in the making of such
      investigation is, in the opinion of the Trustee, not reasonably assured
      to the Trustee by the security afforded to it by the terms of this
      Agreement, the Trustee may require reasonable indemnity against such
      cost, expense or liability as a condition to such proceeding. The
      reasonable expense of every such examination shall be paid by the
      Servicer or, if paid by the Trustee, shall be reimbursed by the Servicer
      upon demand. Nothing in this clause (v) shall derogate from the
      obligation of the Servicer to observe any applicable law prohibiting
      disclosure of information regarding the Mortgagors;

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

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

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

            Section 8.03      Trustee Not Liable for Certificates or Mortgage
Loans.

            The recitals contained herein and in the Certificates (other than
the authentication of the Trustee on the Certificates) shall be taken as the
statements of the Seller, and the Trustee assumes no responsibility for the
correctness of the same. The Trustee makes no representations as to the
validity or sufficiency of this Agreement or of the Certificates (other than
the signature of the Trustee and authentication of the Trustee on the
Certificates) or of any Mortgage Loan or Related Document. The Trustee shall
not be accountable for the use or application by the Servicer, or for the use
or application of any funds paid to the Servicer in respect of the Mortgage
Loans or deposited in or withdrawn from the Collection Account by the
Servicer. The Trustee shall not at any time have any responsibility or
liability for or with respect to the legality, validity and enforceability of
any Mortgage or any Mortgage Loan, or the perfection and priority of any
Mortgage or the maintenance of any such perfection and priority, or for or
with respect to the sufficiency of the Trust or its ability to generate the
payments to be distributed to Certificateholders under this Agreement,
including, without limitation: the existence, condition

                                    -117-
<PAGE>

and ownership of any Mortgaged Property; the existence and enforceability of
any hazard insurance thereon (other than if the Trustee shall assume the
duties of the Servicer pursuant to Section 7.02); the validity of the
assignment of any Mortgage Loan to the Trustee or of any intervening
assignment; the completeness of any Mortgage Loan; the performance or
enforcement of any Mortgage Loan (other than if the Trustee shall assume the
duties of the Servicer pursuant to Section 7.02); the compliance by the
Depositor, the Seller or the Servicer with any warranty or representation made
under this Agreement or in any related document or the accuracy of any such
warranty or representation prior to the Trustee's receipt of notice or other
discovery of any non-compliance therewith or any breach thereof; any
investment of monies by or at the direction of the Servicer or any loss
resulting therefrom, it being understood that the Trustee shall remain
responsible for any Trust property that it may hold in its individual
capacity; the acts or omissions of any of the Servicer (other than if the
Trustee shall assume the duties of the Servicer pursuant to Section 7.02), or
any Mortgagor; any action of the Servicer (other than if the Trustee shall
assume the duties of the Servicer pursuant to Section 7.02), taken in the name
of the Trustee; the failure of the Servicer to act or perform any duties
required of it as agent of the Trustee hereunder; or any action by the Trustee
taken at the instruction of the Servicer (other than if the Trustee shall
assume the duties of the Servicer pursuant to Section 7.02); provided,
however, that the foregoing shall not relieve the Trustee of its obligation to
perform its duties under this Agreement. The Trustee shall not have any
responsibility for filing any financing or continuation statement in any
public office at any time or to otherwise perfect or maintain the perfection
of any security interest or lien granted to it hereunder.

            Section 8.04      Trustee May Own Certificates.

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

            Section 8.05      Seller to Pay Trustee Fees and Expenses.

            The Trustee shall withdraw from the Distribution Account on each
Distribution Date and pay to itself its fees in an aggregate amount equal to
the Trustee Fee pursuant to Section 4.01 and, to the extent the sum of the
Interest Remittance Amount is at any time insufficient for such purpose, the
Seller shall pay such fees as reasonable compensation (which shall not be
limited by any provision of law in regard to the compensation of a trustee of
an express trust) for all services rendered by it in the execution of the
trusts hereby created and in the exercise and performance of any of the powers
and duties hereunder of the Trustee, and the Seller will pay or reimburse the
Trustee upon their request for all reasonable expenses, disbursements and
advances incurred or made by the Trustee in accordance with any of the
provisions of this Agreement (including the reasonable compensation and the
expenses and disbursements of its counsel and of all persons not regularly in
its employ) except any such expense, disbursement or advance as may arise from
such party's negligence or bad faith or which is the responsibility of
Certificateholders or the Trustee hereunder. Notwithstanding any other
provision of this Agreement, including Section 2.03(a) and Section 2.04, to
the contrary, the Seller covenants and agrees to indemnify the Trustee and its
respective officers, directors, employees and agents from, and hold each of
them harmless against, any and all losses,

                                    -118-
<PAGE>

liabilities, damages, claims or expenses incurred in connection with any legal
action relating to this Agreement, the Certificates or incurred in connection
with the administration of the Trust, other than with respect to a party, any
loss, liability or expense incurred by reason of willful misfeasance, bad
faith or negligence of such party in the performance of their respective
duties hereunder or by reason of such party's reckless disregard of
obligations and duties hereunder. Anything in this Agreement to the contrary
notwithstanding, in no event shall the Trustee be liable for special, indirect
or consequential loss or damage of any kind whatsoever (including but not
limited to lost profits), even if the Trustee has been advised of the
likelihood of such loss or damage and regardless of the form of action. The
Trustee and any director, officer, employee or agent of the Trustee shall be
indemnified, to the extent not paid by the Seller pursuant to this Section, by
the Trust Fund and held harmless against any loss, liability or expense (not
including expenses, disbursements and advances incurred or made by the
Trustee, in the ordinary course of the Trustee's performance in accordance
with the provisions of this Agreement) incurred by the Trustee or such party
arising out of or in connection with the acceptance or administration of its
duties under this Agreement, other than any loss, liability or expense
incurred by reason of willful misfeasance, bad faith or negligence in the
performance by the Trustee of its duties under this Agreement or by reason of
the reckless disregard of the Trustee's obligations and duties under this
Agreement. This section shall survive termination of this Agreement or the
resignation or removal of any Trustee hereunder.

            Section 8.06      Eligibility Requirements for Trustee.

            The Trustee hereunder shall at all times be a Department of
Housing and Urban Development and Federal Housing Administration approved
mortgagee, 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. If such entity
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 8.06, the combined capital and surplus of such entity
shall be deemed to be its combined capital and surplus as set forth in its
most recent report of condition so published. The principal office of the
Trustee (other than the initial Trustee) shall be in a state with respect to
which an Opinion of Counsel has been delivered to such Trustee at the time
such Trustee is appointed Trustee to the effect that the Trust will not be a
taxable entity under the laws of such state. In case at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section
8.06, the Trustee shall resign immediately in the manner and with the effect
specified in Section 8.07.

            Section 8.07      Resignation or Removal of Trustee.

            The Trustee may at any time resign and be discharged from the
trusts hereby created by giving written notice thereof to the Depositor, the
Servicer and each Rating Agency. Upon receiving such notice of resignation,
the Depositor shall promptly appoint a successor Trustee by written
instrument, in duplicate, one copy of which instrument shall be delivered to
the resigning Trustee and one copy to the successor Trustee. If no successor
Trustee shall have been so appointed and having accepted appointment within 30
days after the giving of such

                                    -119-
<PAGE>

notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

            If at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.06 and shall fail to resign after
written request therefor by the Depositor, or if at any time the Trustee shall
be legally unable to act, or shall be adjudged a bankrupt or insolvent, or a
receiver of the Trustee or of their property shall be appointed, or any public
officer shall take charge or control of the Trustee or of their property or
affairs for the purpose of rehabilitation, conservation or liquidation, then
the Depositor may remove the Trustee. If the Depositor or the Servicer removes
the Trustee under the authority of the immediately preceding sentence, the
Depositor shall promptly appoint a successor Trustee by written instrument, in
duplicate, one copy of which instrument shall be delivered to the Trustee so
removed and one copy to the successor Trustee.

            The Majority Certificateholders may at any time remove the Trustee
by written instrument or instruments delivered to the Servicer, the Depositor
and the Trustee and any expenses incurred by the Trustee in connection with
such removal shall be reimbursed to it by the Majority Certificateholders
promptly upon demand therefor; the Depositor shall thereupon use its best
efforts to appoint a successor Trustee in accordance with this Section.

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

            Section 8.08      Successor Trustee.

            Any successor Trustee appointed as provided in Section 8.07 shall
execute, acknowledge and deliver to the Depositor, the Rating Agencies, the
Servicer and to its predecessor Trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor Trustee shall become effective, and such successor Trustee,
without any further act, deed or conveyance, shall become fully vested with
all the rights, powers, duties and obligations of its predecessor hereunder,
with like effect as if originally named as Trustee. The Depositor, the
Servicer and the predecessor Trustee shall execute and deliver such
instruments and do such other things as may reasonably be required for fully
and certainly vesting and confirming in the successor Trustee all such rights,
powers, duties and obligations.

            No successor Trustee shall accept appointment as provided in this
Section 8.08 unless at the time of such acceptance such successor Trustee
shall be eligible under the provisions of Section 8.06 and the appointment of
such successor Trustee shall not result in a downgrading of the Regular
Certificates by any Rating Agency, as evidenced by a letter from each Rating
Agency.

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

                                    -120-

            Section 8.09      Merger or Consolidation of Trustee.

            Any entity into which the Trustee may be merged or converted or
with which it may be consolidated, or any entity resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
entity succeeding to the business of the Trustee, shall be the successor of
the Trustee 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 Depositor and the Trustee acting jointly shall have the power and
shall execute and deliver all instruments to appoint one or more Persons
approved by the Trustee to act as co-trustee or co-trustees, jointly with the
Trustee, or separate trustee or separate trustees, of all or any part of the
Trust, and to vest in such Person or Persons, in such capacity and for the
benefit of the Certificateholders, such title to the Trust, or any part
thereof, and, subject to the other provisions of this Section 8.10, such
powers, duties, obligations, rights and trusts as the Servicer and the Trustee
may consider necessary or desirable. Any such co-trustee or separate trustee
shall be subject to the written approval of the Servicer. If the Servicer
shall not have joined in such appointment within 15 days after the receipt by
it of a request so to do, or in the case a Servicer Event of Termination shall
have occurred and be continuing, the Trustee alone shall have the power to
make such appointment. No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor Trustee under Section
8.06, and no notice to Certificateholders of the appointment of any co-trustee
or separate trustee shall be required under Section 8.08. The Servicer shall
be responsible for the fees of any co-trustee or separate trustee appointed
hereunder.

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

            (i) all rights, powers, duties and obligations conferred or
      imposed upon the Trustee shall be conferred or imposed upon and
      exercised or performed by the Trustee and such separate trustee or
      co-trustee jointly (it being understood that such separate trustee or
      co-trustee is not authorized to act separately without the Trustee
      joining in such act), except to the extent that under any law of any
      jurisdiction in which any particular act or acts are to be performed
      (whether as Trustee hereunder or as successor to the Servicer
      hereunder), the Trustee shall be incompetent or unqualified to perform
      such act or acts, in which event such rights, powers, duties and
      obligations (including the holding of title to the Trust or any portion
      thereof in any such jurisdiction) shall be exercised and performed
      singly by such separate trustee or co-trustee, but solely at the
      direction of the Trustee;

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

                                    -121-
<PAGE>

            (iii) the Servicer and the Trustee, acting jointly may at any time
      accept the resignation of or remove any separate trustee or co-trustee
      except that following the occurrence of a Servicer Event of Termination,
      the Trustee acting alone may accept the resignation or remove any
      separate trustee or co-trustee.

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

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

            Section 8.11      Limitation of Liability.

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

            Section 8.16      Compliance with National Housing Act of 1934.

            Section 9.01      REMIC Administration.

            (a) The Trustee shall make or cause to be made REMIC elections for
each REMIC designated as such in the Preliminary Statement on Forms 1066 or

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.

                                    -123-
<PAGE>

            (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 Servicer 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 Servicer in fulfilling its
duties hereunder. The Servicer shall be entitled to reimbursement of expenses
to the extent provided in clause (i) above from the Collection Account.

            (d) The Trustee shall prepare, sign and file, all of the REMICs'
federal and state tax and information returns as the direct representative of
each REMIC created hereunder. The expenses of preparing and filing such
returns shall be borne by the Trustee.

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

            (f) The Trustee, the Servicer, and the Holders of Certificates
shall take any action or cause any REMIC 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. Neither the Trustee, the Servicer, nor the Holder of any Residual
Certificate shall take any action or cause any REMIC to take any action or
fail to take (or fail to cause to be taken) any action that, under the REMIC
Provisions, if taken or not taken, as the case may be, could (i) endanger the
status of 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 such action or failure to act is expressly permitted under the
terms of this Agreement or the Trustee and the Servicer have received an
Opinion of Counsel (at the expense of the party seeking to take such action)
to the effect that the contemplated action will not endanger such status or
result in the imposition of such a tax. In addition, prior to taking any
action with respect to any REMIC 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 a Residual Certificate will consult with the

                                    -124-
<PAGE>

Trustee and the Servicer, or their respective designees, in writing, with
respect to whether such action could cause an Adverse REMIC Event to occur
with respect to such REMIC, and no such Person shall take any such action or
cause such REMIC to take any such action as to which the Trustee or the
Servicer has advised it in writing that an Adverse REMIC Event could occur.

            (g) Each Holder of a Residual Certificate shall pay when due its
pro rata share of any and all taxes imposed on any REMIC by federal or state
governmental authorities. To the extent that such REMIC taxes are not paid by
Residual Certificateholders, the Trustee shall pay any remaining REMIC taxes
out of current or future amounts otherwise distributable to the Holder of the
Residual Certificate in each REMIC or, if no such amounts are available, out
of other amounts held in the Collection Account, and shall reduce amounts
otherwise payable to Holders of the REMIC Regular Interests or the
Certificates, as the case may be.

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

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

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

            (k) On or before April 15 of each calendar year beginning in 2006,
the Servicer shall deliver to the Trustee and each Rating Agency an Officer's
Certificate stating the Servicer's compliance with the provisions of this
Section 9.01.

            (l) The Trustee shall treat the rights of each Class of
Certificates entitled to receive Net Rate Carryover Amounts as rights in
interest rate cap contracts written by the Holders of the Class N and Class X
Certificates in favor of the Holders of the such Classes of Certificates, and
the Trustee shall account for such as property held separate and apart from
the regular interests it holds in each of the REMICs created hereunder. This
provision is 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 that any such
Certificates receive interest in excess of the applicable Net Rate Cap, such
interest will be treated as distributed to the Class N and Class X
Certificates in respect of interest on the Class X Interest and then paid to
the respective Class Certificates entitled to Net Rate Carryover Amounts
pursuant to the related interest rate cap agreement.

            (m) [Reserved]

            (n) In the event that any Person holds pro rata shares of the
ownership of the Class N Certificates and the Class X Certificates (any such
Person, a "Proportionate Holder"), the Trustee shall treat such Person as the
holder of the ownership of the same pro-rata share of the Class X Interest. In
the event that any Person holds non-pro rata shares of the ownership of the
Class N Certificates and the Class X Certificates (any such Person, a
"Disproportionate Holder"), the Trustee shall treat such Person, and all other
Disproportionate Holders, as partners

                                    -125-
<PAGE>

in a partnership that owns the Class X Interest (other than the shares of the
Class X Interest held by any Proportionate Holders) for federal income tax
purposes and shall not treat the Class N and Class X Certificates held by the
Disproportionate Holders as interests in any REMIC created hereunder. By
acquiring the Class N Certificates and the Class X Certificates, the
respective Holders will agree to treat the Class N Certificates and the Class
X Certificates in the manner described in the preceding sentences for federal
income tax purposes. In such event, (i) a separate capital account shall be
established and maintained for each Holder of a Class N or Class X Certificate
in accordance with Treasury Regulation Section 1.704-1(b)(2)(iv), which shall
be credited with income or gain and debited by any expenses or losses and
distributions allocable to such Certificates, (ii) the Class N Certificates
shall be allocated income in an amount equal to interest at the Pass-Through
Rate thereon and any original issue discount that would be reportable thereon
if the Class N Certificate were a debt instrument issued on the date ownership
of the Class N and Class X Certificates is separated, with a principal balance
equal to its Notional Amount, (iii) the Class X and Class N Certificates shall
be allocated income with respect to all Prepayment Charges (including amounts
in connection with the full or partial waiver of such Prepayment Charge
pursuant to Section 3.01) in accordance with the allocation of such amounts
pursuant to Section 4.02(c), to the extent not allocated pursuant to Section
9.01(n)(ii) above, (iv) the Class X and Class N Certificates shall be
allocated accruals (under any reasonable method) of any "cap premiums" deemed
received on the date ownership of the Class X and Class N Certificates is
separated in respect of the obligation of the Class X Interest to pay Net Rate
Carryover Amounts, and shall be allocated expense in respect of any actual
payment of such Net Rate Carryover Amounts based on which one of such Classes
economically bears such expense, (v) the Class X Certificates shall be
allocated all remaining income and any expenses and Realized Losses with
respect to the Class X Interest, until the capital account of the Class X
Certificates is reduced to zero, and any remaining expenses or losses shall be
allocated to the Class N Certificates, (vi) neither the Class N Certificates
nor the Class X Certificates shall be responsible for restoring any deficit to
its capital account, (vii) upon termination of the Trust Fund pursuant to
Article X, all amounts available for distribution to Holders of the Class N
and Class X Certificates shall be distributed in accordance with their
positive capital account balances, first to the Class N Certificates until
their Notional Amount and any accrued but unpaid interest thereon are reduced
to zero, and then to the Class X Certificates, and (viii) the Trustee shall
maintain books and records with respect to the partnership on a calendar year
basis (unless a different taxable year shall be required by the Code) and
shall prepare or cause to be prepared, and cause the Holder of the largest
Percentage Interest of the Class X Certificates to sign and file or cause to
be filed all federal and state tax and information returns for the
partnership, and shall furnish or cause to be furnished Schedule K-1's to the
Holders of the Class N and Class X Certificates at the time required by the
Code. Unless otherwise directed by a majority of the Percentage Interests of
the Class X and Class N Certificates, the Trustee shall not make an election
under Section 754 of the Code. The Holder of the largest Percentage Interest
of the Class X Certificates, by acceptance of its Class X Certificate, agrees
to act as "tax matters partner" (within the meaning of Section 6231(a)(7) of
the Code and to sign and timely file all federal and state partnership tax and
information returns prepared by the Trustee pursuant to this Section 9.01(n).

            (o) The Trustee shall treat the Basis Risk Reserve Fund as outside
reserve funds within the meaning of Treasury Regulation 1.860G-2(h) that are
owned by the Class N and Class X Certificateholders and that are not assets of
the REMICs. The Trustee shall treat the rights of

                                    -126-
<PAGE>

the Class AV Certificates and the Subordinated Certificates to receive
payments from the Basis Risk Reserve Fund as rights in interest rate cap
contracts written by the Holders of the Class X Interest (in the case of
amounts payable from the Basis Risk Reserve Fund)in favor of the the Class AV
Certificateholders and the Subordinated Certificateholders. Thus, each
Certificate other than the Class N and Class X Certificates shall be treated
as representing ownership of not only REMIC Regular Interests, but also
ownership of an interest in one or more interest rate cap contracts.

            Section 9.02      Prohibited Transactions and Activities.

            Neither the Seller, the Depositor, the Servicer nor the Trustee
shall sell, dispose of, or substitute for any of the Mortgage Loans, except in
a disposition pursuant to (i) the foreclosure of a Mortgage Loan, (ii) the
bankruptcy of the Trust Fund, (iii) the termination of 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, nor sell or dispose of
any investments in the Distribution Account for gain, nor accept any
contributions to any REMIC after the Closing Date, unless it has received an
Opinion of Counsel (at the expense of the party causing such sale,
disposition, or substitution) that such disposition, acquisition,
substitution, or acceptance will not (a) affect adversely the status of such
REMIC as a REMIC or of the interests therein other than the Residual
Certificates as the regular interests therein, (b) affect the distribution of
interest or principal on the Certificates, (c) result in the encumbrance of
the assets transferred or assigned to the Trust Fund (except pursuant to the
provisions of this Agreement) or (d) cause such REMIC to be subject to a tax
on prohibited transactions or prohibited contributions pursuant to the REMIC
Provisions.

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

            In the event that any REMIC formed hereunder fails to qualify as a
REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as
a result of a prohibited transaction or prohibited contribution under the
REMIC Provisions due to the negligent performance by the Servicer of its
duties and obligations set forth herein, the Servicer shall indemnify the
Holder of the related Residual Certificate against any and all losses, claims,
damages, liabilities or expenses ("Losses") resulting from such negligence;
provided, however, that the Servicer shall not be liable for any such Losses
attributable to the action or inaction of the Trustee, the Depositor or the
Holder of such Residual Certificate, as applicable, nor for any such Losses
resulting from misinformation provided by the Holder of such Residual
Certificate on which the Servicer has relied. The foregoing shall not be
deemed to limit or restrict the rights and remedies of the Holder of such
Residual Certificate now or hereafter existing at law or in equity.
Notwithstanding the foregoing, however, in no event shall the Servicer have
any liability (1) for any action or omission that is taken in accordance with
and in compliance with the express terms of, or which is expressly permitted
by the terms of, this Agreement, (2) for any Losses other than arising out of
a negligent performance by the Servicer of its duties and obligations set
forth herein, and (3) for any special or consequential damages to
Certificateholders (in addition to payment of principal and interest on the
Certificates).

                                  TERMINATION

            Section 10.01     Termination.

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

            The Servicer or an Affiliate of the Servicer may, at its option,
terminate the Mortgage Loans in the Trust Fund and retire the Certificates on
the next succeeding Distribution Date upon which the aggregate current Pool
Balance is less than or equal to 10% of the aggregate Pool Balance of the
Mortgage Loans as of the Cut-off Date by purchasing all of the outstanding (i)
Mortgage Loans in the Trust Fund at a price equal to the sum of the
outstanding Principal Balance of the Mortgage Loans and except to the extent
previously advanced by the Servicer, accrued and unpaid interest thereon at
the weighted average of the Mortgage Interest Rates through the end of the
Collection Period preceding the final Distribution Date plus unreimbursed
Servicing Advances, Advances and any unpaid Servicing Fees allocable to such
Mortgage Loans and (ii) REO Properties in the Trust Fund at a price equal to
their fair market value as determined in good faith by the Servicer (the
"Termination Price").

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

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

            (b) Notice of any termination, specifying the Distribution Date
(which shall be a date that would otherwise be a Distribution Date) upon which
the Certificateholders may surrender their Certificates to the Trustee for
payment of the final distribution and cancellation, shall be given promptly by
the Trustee upon the Trustee receiving notice of such date from the Servicer,
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

                                    -128-
<PAGE>

Certificates will be made upon presentation and surrender of such Certificates
at the office or agency of the Trustee therein designated, (2) the amount of
any such final distribution and (3) that the Record Date otherwise applicable
to such Distribution Date is not applicable, distributions being made only
upon presentation and surrender of the Certificates at the office or agency of
the Trustee therein specified.

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

            (d) In the event that all Certificateholders shall not surrender
their Certificates for final payment and cancellation on or before such final
Distribution Date, the Trustee shall promptly following such date cause all
funds in the Distribution Account not distributed in final distribution to
Certificateholders to be withdrawn therefrom and credited to the remaining
Certificateholders by depositing such funds in a separate escrow account for
the benefit of such Certificateholders, and the Servicer (if the Servicer has
exercised its right to purchase the Mortgage Loans) or the Trustee (in any
other case) 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 Certificateholders shall be entitled to all
unclaimed funds and other assets which remain subject hereto (except with
respect to the Class M-6, Class N and Class X Certificates and the assets of
the Class M-6 REMIC and the Class X REMIC) and the Trustee upon transfer of
such funds shall be discharged of any responsibility for such funds, and such
Certificateholders shall look to the Class R Certificateholders for payment.
The Class XR Certificateholders shall be entitled to all unclaimed funds and
other assets with respect to the Class M-6 REMIC and the Class X REMIC.
Holders of the Class M-6 Certificates (representing beneficial ownership of
the Class M-6 Regular Interest) and Class N and Class X Certificates
(representing partners in a partnership which beneficially owns the Class X
REMIC Regular Interest) shall be entitled to look only to the Class XR
Certificateholder for payment.

            Section 10.02     Additional Termination Requirements.

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

            (i) The Trustee shall designate a date within 90 days prior to the
      final Distribution Date as the date of adoption of plans of complete

      income tax return of each REMIC;

      Certificates, the Trustee shall distribute or credit, or cause to be
      distributed or credited in the following order of priority (A) (i) to
      the Holders of each of the Class AV and Class AF Certificates, pro rata,
      (ii) to the Subordinate Certificates, the related Certificate Principal

      amounts allocable thereto pursuant to Section 4.08 and (D) to the Class
      R Certificateholders, all cash on hand in respect of the related REMIC
      or REMICs after such payment (other than cash retained to meet claims)
      and the Trust shall terminate at such time.

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

            (c) Notwithstanding any other provision of this Agreement, the
Class M-6 REMIC will terminate on the last Distribution Date on which the
Class M-6 Certificates, respectively, are entitled to distributions pursuant
to this Agreement.

then outstanding. Upon approval of an amendment, a copy of such amendment
shall be sent to the Rating Agencies. Prior to the execution of any amendment
to this Agreement, the Trustee shall be entitled to receive and rely upon an
Opinion of Counsel (at the expense of the Person seeking such amendment)
stating that the execution of such amendment is authorized or permitted by
this Agreement. The Trustee may, but shall not be obligated to, enter into any
such amendment which affects the Trustee's own rights, duties or immunities
under this Agreement.

            Notwithstanding any provision of this Agreement to the contrary,
the Trustee shall not 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 to fail to qualify as a REMIC 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 Trustee
shall furnish, at the expense of the Person that requested the amendment if
such Person is the Seller or the Servicer (but in no event at the expense of
the Trustee), otherwise at the expense of the Trust, a copy of such amendment
and the Opinion of Counsel referred to in the immediately preceding paragraph
to the Servicer and each Rating Agency.

            It shall not be necessary for the consent of Certificateholders
under this Section 11.01 to approve the particular form of any proposed
amendment; instead it shall be sufficient if such consent shall approve the
substance thereof. The manner of obtaining such consents and of evidencing the
authorization of the execution thereof by Certificateholders shall be subject
to such reasonable regulations as the Trustee may prescribe.

            Section 11.02     Recordation of Agreement; Counterparts.

            To the extent permitted by applicable law, this Agreement is
subject to recordation in all appropriate public offices for real property
records in all the counties or other comparable jurisdictions in which any or
all of the properties subject to the Mortgages are

                                    -131-
<PAGE>

situated, and in any other appropriate public recording office or elsewhere,
such recordation to be effected by the Servicer at the expense of the Trust,
but only upon direction of Certificateholders, accompanied by an Opinion of
Counsel to the effect that such recordation materially and beneficially
affects the interests of the Certificateholders.

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

            Section 11.03     Limitation on Rights of Certificateholders.

            The death or incapacity of any Certificateholder shall not (i)
operate to terminate this Agreement or the Trust, (ii) entitle such
Certificateholder's legal representatives or heirs to claim an accounting or
to take any action or proceeding in any court for a partition or winding up of
the Trust, or (iii) otherwise affect the rights, obligations and liabilities
of the parties hereto or any of them.

            Except as expressly provided for herein, no Certificateholder
shall have any right to vote or in any manner otherwise control the operation
and management of the Trust, or the obligations of the parties hereto, nor
shall anything herein set forth or contained in the terms of the Certificates
be construed so as to constitute the Certificateholders from time to time as
partners or members of an association; nor shall any Certificateholder be
under any liability to any third person by reason of any action taken by the
parties to this Agreement pursuant to any provision hereof.

            No Certificateholder shall have any right by virtue of any
provision of this Agreement to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Agreement, unless such
Holder previously shall have given to the Trustee a written notice of default
and of the continuance thereof, as herein provided, and unless also the
Holders of Certificates entitled to at least 25% of the Voting Rights shall
have made written request upon the Trustee to institute such action, suit or
proceeding in its own name as Trustee hereunder and shall have offered to the
Trustee such reasonable indemnity as it may require against the costs,
expenses and liabilities to be incurred therein or thereby, and the Trustee
for 15 days after its receipt of such notice, request and offer of indemnity,
shall have neglected or refused to institute any such action, suit or
proceeding. It is understood and intended, and expressly covenanted by each
Certificateholder with every other Certificateholder and the Trustee, that no
one or more Holders of Certificates shall have any right in any manner
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.

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,

            Section 11.09     Further Assurances.

            Notwithstanding any other provision of this Agreement, neither the
Regular Certificateholders 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

            Section 11.10     Benefits of Agreement.

            Nothing in this Agreement or in the Certificates, expressed or
implied, shall give to any Person, other than the Certificateholders and the
parties hereto and their successors hereunder, any benefit or any legal or
equitable right, remedy or claim under this Agreement.

            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 Seller and the Servicer. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "act" of the Certificateholders signing such
instrument or instruments. Proof of execution of any such instrument or of a
writing appointing any such agent shall be sufficient for any purpose of this

manner provided in this Section 11.11.

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 or the Trust in reliance thereon, whether or not notation of such
action is made upon such Certificate.

     This Certificate is one of a duly authorized issue of Certificates
designated as C-BASS Mortgage Loan Asset-Backed Certificates, Series 2005-CB1
(herein collectively called the "Certificates"), and representing a beneficial
ownership interest in the Trust created by the Agreement.

     The Certificateholder, by its acceptance of this Certificate, agrees that
it will look solely to the funds on deposit in the Distribution Account for
payment hereunder and that the Trustee is not liable to the Certificateholders
for any amount payable under this Certificate or the Agreement or, except as
expressly provided in the Agreement, subject to any liability under the
Agreement.

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

     Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business
on the applicable Record Date in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to
be distributed to Holders of Certificates of the Class to which this
Certificate belongs on such Distribution Date pursuant to the Agreement.

     Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or, upon the request of a Certificateholder owning
Regular Certificates of a Class having Denominations aggregating at least
$5,000,000, by wire transfer or otherwise, as set forth in the Agreement. The
final distribution on each Certificate will be made in like manner, but only

the Trustee specified in the notice to Certificateholders of such final
distribution.

     The Agreement permits, with certain exceptions therein provided, the

time by the Depositor, the Seller, the Servicer and the Trustee with the
consent of Holders of the requisite percentage of the Percentage Interests of
each Class of Certificates affected by such amendment, as specified 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 therefor 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 office or agency maintained by the Trustee in New York, New York
accompanied by a written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by the holder hereof or
such holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest in the Trust will be issued to the
designated transferee or transferees.

     The Certificates are issuable only as registered Certificates without
coupons in denominations 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 and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

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

     On any Distribution Date following the date at which the Pool Balance is
equal to or less than 10% of the Pool Balance as of the Cut-off Date, the
Servicer (or one of its Affiliates) may purchase, in whole, from the Trust the
Mortgage Loans at a purchase price determined as provided in the Agreement. In
the event that no such optional termination occurs, the obligations and
responsibilities created by the Agreement will terminate upon the earlier of
(i) the Distribution Date on which the Certificate Principal Balance of each
Class of Certificates has been reduced to zero and (ii) the final payment or
other liquidation of the last Mortgage Loan in the Trust. In no event,
however, will the trust created by the Agreement continue beyond the
expiration of 21 years from the death of the last survivor of the descendants
living at the date of the Agreement of a certain person named in the
Agreement.

     Capitalized terms used herein that are defined in the Agreement shall
have the meanings ascribed to them in the Agreement, and nothing herein shall
be deemed inconsistent with that meaning.

designated as C-BASS Mortgage Loan Asset-Backed Certificates, Series 2005-CB1
(herein collectively called the "Certificates"), and representing a beneficial
ownership interest in the Trust created by the Agreement.

     The Certificateholder, by its acceptance of this Certificate, agrees that

payment hereunder and that the Trustee is not liable to the Certificateholders
for any amount payable under this Certificate or the Agreement or, except as
expressly provided in the Agreement, subject to any liability under the
Agreement.

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

     Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business
on the applicable Record Date in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to
be distributed to Holders of Certificates of the Class to which this
Certificate belongs on such Distribution Date pursuant to the Agreement.

     Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or, upon the request of a Certificateholder owning
Regular Certificates of a Class having Denominations aggregating at least
$5,000,000, by wire transfer or otherwise, as set forth in the Agreement. The
final distribution on each Certificate will be made in like manner, but only
upon presentment and surrender of such Certificate at the office or agency of
the Trustee specified in the notice to Certificateholders of such final
distribution.

     The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the

time by the Depositor, the Seller, the Servicer and the Trustee with the
consent of Holders of the requisite percentage of the Percentage Interests of
each Class of Certificates affected by such amendment, as specified 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 therefor 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 office or agency maintained by the Trustee in New York, New York
accompanied by a written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by the holder hereof or
such holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest in the Trust will be issued to the
designated transferee or transferees.

     The Certificates are issuable only as registered Certificates without
coupons in denominations 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 and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

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

     On any Distribution Date following the date at which the Pool Balance is
equal to or less than 10% of the Pool Balance as of the Cut-off Date, the
Servicer (or one of its Affiliates) may purchase, in whole, from the Trust the
Mortgage Loans at a purchase price determined as provided in the Agreement. In
the event that no such optional termination occurs, the obligations and
responsibilities created by the Agreement will terminate upon the earlier of
(i) the Distribution Date on which the Certificate Principal Balance of each
Class of Certificates has been reduced to zero and (ii) the final payment or
other liquidation of the last Mortgage Loan in the Trust. In no event,
however, will the trust created by the Agreement continue beyond the
expiration of 21 years from the death of the last survivor of the descendants
living at the date of the Agreement of a certain person named in the
Agreement.

     Capitalized terms used herein that are defined in the Agreement shall
have the meanings ascribed to them in the Agreement, and nothing herein shall
be deemed inconsistent with that meaning.

Agreement.

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

     Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business
on the applicable Record Date in an amount equal to the product of the

Certificate belongs on such Distribution Date pursuant to the Agreement.

     Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the

$5,000,000, by wire transfer or otherwise, as set forth in the Agreement. The
final distribution on each Certificate will be made in like manner, but only

the Trustee specified in the notice to Certificateholders of such final
distribution.

     The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any
time by the Depositor, the Seller, the Servicer and the Trustee with the
consent of Holders of the requisite percentage of the Percentage Interests of
each Class of Certificates affected by such amendment, as specified 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 therefor 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 office or agency maintained by the Trustee in New York, New York
accompanied by a written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by the holder hereof or
such holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest in the Trust will be issued to the
designated transferee or transferees.

     The Certificates are issuable only as registered Certificates without
coupons in denominations 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 and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

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

     On any Distribution Date following the date at which the Pool Balance is
equal to or less than 10% of the Pool Balance as of the Cut-off Date, the
Servicer (or one of its Affiliates) may purchase, in whole, from the Trust the
Mortgage Loans at a purchase price determined as provided in the Agreement. In
the event that no such optional termination occurs, the obligations and
responsibilities created by the Agreement will terminate upon the earlier of
(i) the Distribution Date on which the Certificate Principal Balance of each
Class of Certificates has been reduced to zero and (ii) the final payment or
other liquidation of the last Mortgage Loan in the Trust. In no event,
however, will the trust created by the Agreement continue beyond the
expiration of 21 years from the death of the last survivor of the descendants
living at the date of the Agreement of a certain person named in the
Agreement.

     Capitalized terms used herein that are defined in the Agreement shall
have the meanings ascribed to them in the Agreement, and nothing herein shall

     The Certificates are issuable only as registered Certificates without
coupons in denominations specified in the Agreement. As provided in the

Class of Certificates has been reduced to zero and (ii) the final payment or
other liquidation of the last Mortgage Loan in the Trust. In no event,
however, will the trust created by the Agreement continue beyond the

     Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or, upon the request of a Certificateholder owning

Certificate and of any Certificate issued upon the transfer hereof or in
exchange therefor 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.

designated as C-BASS Mortgage Loan Asset-Backed Certificates, Series 2005-CB1
(herein collectively called the "Certificates"), and representing a beneficial
ownership interest in the Trust created by the Agreement.

     The Certificateholder, by its acceptance of this Certificate, agrees that
it will look solely to the funds on deposit in the Distribution Account for
payment hereunder and that the Trustee is not liable to the Certificateholders
for any amount payable under this Certificate or the Agreement or, except as
expressly provided in the Agreement, subject to any liability under the
Agreement.

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

     Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business
on the applicable Record Date in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to
be distributed to Holders of Certificates of the Class to which this
Certificate belongs on such Distribution Date pursuant to the Agreement.

     Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or, upon the request of a Certificateholder owning
Regular Certificates of a Class having Denominations aggregating at least
$5,000,000, by wire transfer or otherwise, as set forth in the Agreement. The
final distribution on each Certificate will be made in like manner, but only
upon presentment and surrender of such Certificate at the office or agency of
the Trustee specified in the notice to Certificateholders of such final
distribution.

     The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any
time by the Depositor, the Seller, the Servicer and the Trustee with the
consent of Holders of the requisite percentage of the Percentage Interests of
each Class of Certificates affected by such amendment, as specified 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 therefor 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 office or agency maintained by the Trustee in New York, New York
accompanied by a written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by the holder hereof or
such holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest in the Trust will be issued to the
designated transferee or transferees.

     The Certificates are issuable only as registered Certificates without
coupons in denominations 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 and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

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

     On any Distribution Date following the date at which the Pool Balance is
equal to or less than 10% of the Pool Balance as of the Cut-off Date, the
Servicer (or one of its Affiliates) may purchase, in whole, from the Trust the
Mortgage Loans at a purchase price determined as provided in the Agreement. In
the event that no such optional termination occurs, the obligations and
responsibilities created by the Agreement will terminate upon the earlier of
(i) the Distribution Date on which the Certificate Principal Balance of each
Class of Certificates has been reduced to zero and (ii) the final payment or
other liquidation of the last Mortgage Loan in the Trust. In no event,
however, will the trust created by the Agreement continue beyond the
expiration of 21 years from the death of the last survivor of the descendants
living at the date of the Agreement of a certain person named in the
Agreement.

     Capitalized terms used herein that are defined in the Agreement shall
have the meanings ascribed to them in the Agreement, and nothing herein shall
be deemed inconsistent with that meaning.

            Principal in respect of this Certificate is distributable monthly

is issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Class M-3 Certificate by
virtue of the acceptance hereof assents and by which such Holder is bound.

     Reference is hereby made to the further provisions of this Class M-3
Certificate set forth on the reverse hereof, which further provisions shall
for all purposes have the same effect as if set forth at this place.

     This Class M-3 Certificate shall not be entitled to any benefit under the

authorized signatory of the Trustee.

                                Series 2005-CB1

     This Certificate is one of a duly authorized issue of Certificates
designated as C-BASS Mortgage Loan Asset-Backed Certificates, Series 2005-CB1
(herein collectively called the "Certificates"), and representing a beneficial
ownership interest in the Trust created by the Agreement.

     The Certificateholder, by its acceptance of this Certificate, agrees that
it will look solely to the funds on deposit in the Distribution Account for
payment hereunder and that the Trustee is not liable to the Certificateholders
for any amount payable under this Certificate or the Agreement or, except as
expressly provided in the Agreement, subject to any liability under the
Agreement.

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

     Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business
on the applicable Record Date in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to
be distributed to Holders of Certificates of the Class to which this
Certificate belongs on such Distribution Date pursuant to the Agreement.

     Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or, upon the request of a Certificateholder owning
Regular Certificates of a Class having Denominations aggregating at least
$5,000,000, by wire transfer or otherwise, as set forth in the Agreement. The
final distribution on each Certificate will be made in like manner, but only
upon presentment and surrender of such Certificate at the office or agency of
the Trustee specified in the notice to Certificateholders of such final
distribution.

     The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any
time by the Depositor, the Seller, the Servicer and the Trustee with the
consent of Holders of the requisite percentage of the Percentage Interests of
each Class of Certificates affected by such amendment, as specified 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 therefor or in lieu hereof whether or not notation of such consent is
made upon

                                      5
<PAGE>

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 office or agency maintained by the Trustee in New York, New York
accompanied by a written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by the holder hereof or
such holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest in the Trust will be issued to the
designated transferee or transferees.

     The Certificates are issuable only as registered Certificates without
coupons in denominations 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 and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

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

     On any Distribution Date following the date at which the Pool Balance is
equal to or less than 10% of the Pool Balance as of the Cut-off Date, the
Servicer (or one of its Affiliates) may purchase, in whole, from the Trust the
Mortgage Loans at a purchase price determined as provided in the Agreement. In
the event that no such optional termination occurs, the obligations and
responsibilities created by the Agreement will terminate upon the earlier of
(i) the Distribution Date on which the Certificate Principal Balance of each
Class of Certificates has been reduced to zero and (ii) the final payment or
other liquidation of the last Mortgage Loan in the Trust. In no event,
however, will the trust created by the Agreement continue beyond the
expiration of 21 years from the death of the last survivor of the descendants
living at the date of the Agreement of a certain person named in the
Agreement.

     Capitalized terms used herein that are defined in the Agreement shall
have the meanings ascribed to them in the Agreement, and nothing herein shall
be deemed inconsistent with that meaning.

                  BOND SECURITIZATION, L.L.C., as Depositor

            Principal in respect of this Certificate is distributable monthly
as set forth herein. Accordingly, the Certificate Principal Balance of this
Class B-3 Certificate at any time may be less than the Initial Certificate

Principal Balance) in certain monthly distributions with respect to a Trust
consisting primarily of the Mortgage Loans deposited by Bond Securitization,
L.L.C. (the "Depositor"). The Trust was created pursuant to a Pooling and
Servicing Agreement dated as of the Cut-off Date specified above (the
"Agreement") among the Depositor, Credit-Based Asset Servicing and
Securitization LLC, as Seller (the "Seller"), Litton Loan Servicing LP, as
Servicer (the "Servicer"), and U.S. Bank National Association, as Trustee (the
"Trustee"). To the extent not defined herein, the capitalized terms used
herein have the meanings assigned in the Agreement. This Class B-3 Certificate
is issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Class B-3 Certificate by
virtue of the acceptance hereof assents and by which such Holder is bound.

      Reference is hereby made to the further provisions of this Class B-3
Certificate set forth on the reverse hereof, which further provisions shall
for all purposes have the same effect as if set forth at this place.

      This Class B-3 Certificate shall not be entitled to any benefit under
the Agreement or be valid for any purpose unless manually countersigned by an
authorized signatory of the Trustee.

                                Series 2005-CB1

      This Certificate is one of a duly authorized issue of Certificates
designated as C-BASS Mortgage Loan Asset-Backed Certificates, Series 2005-CB1
(herein collectively called the "Certificates"), and representing a beneficial
ownership interest in the Trust created by the Agreement.

      The Certificateholder, by its acceptance of this Certificate, agrees
that it will look solely to the funds on deposit in the Distribution Account
for payment hereunder and that the Trustee is not liable to the
Certificateholders for any amount payable under this Certificate or the
Agreement or, except as expressly provided in the Agreement, subject to any
liability under the Agreement.

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

      Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business
on the applicable Record Date in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to
be distributed to Holders of Certificates of the Class to which this
Certificate belongs on such Distribution Date pursuant to the Agreement.

      Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or, upon the request of a Certificateholder owning
Regular Certificates of a Class having Denominations aggregating at least
$5,000,000, by wire transfer or otherwise, as set forth in the Agreement. The
final distribution on each Certificate will be made in like manner, but only
upon presentment and surrender of such Certificate at the office or agency of
the Trustee specified in the notice to Certificateholders of such final
distribution.

      The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any
time by the Depositor, the Seller, the Servicer and the Trustee with the
consent of Holders of the requisite percentage of the Percentage Interests of
each Class of Certificates affected by such amendment, as specified 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 therefor or in lieu hereof whether or not notation of such consent is
made upon

                                      5
<PAGE>

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 office or agency maintained by the Trustee in New York, New York
accompanied by a written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by the holder hereof or
such holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest in the Trust will be issued to the
designated transferee or transferees.

      The Certificates are issuable only as registered Certificates without
coupons in denominations 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 and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

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

      On any Distribution Date following the date at which the Pool Balance is
equal to or less than 10% of the Pool Balance as of the Cut-off Date, the
Servicer (or one of its Affiliates) may purchase, in whole, from the Trust the
Mortgage Loans at a purchase price determined as provided in the Agreement. In
the event that no such optional termination occurs, the obligations and
responsibilities created by the Agreement will terminate upon the earlier of
(i) the Distribution Date on which the Certificate Principal Balance of each
Class of Certificates has been reduced to zero and (ii) the final payment or
other liquidation of the last Mortgage Loan in the Trust. In no event,
however, will the trust created by the Agreement continue beyond the
expiration of 21 years from the death of the last survivor of the descendants
living at the date of the Agreement of a certain person named in the
Agreement.

      Capitalized terms used herein that are defined in the Agreement shall
have the meanings ascribed to them in the Agreement, and nothing herein shall
be deemed inconsistent with that meaning.

on the applicable Record Date in an amount equal to the product of the

      Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or, upon the request of a Certificateholder owning
Regular Certificates of a Class having Denominations aggregating at least
$5,000,000, by wire transfer or otherwise, as set forth in the Agreement. The
final distribution on each Certificate will be made in like manner, but only
upon presentment and surrender of such Certificate at the office or agency of

      The Agreement permits, with certain exceptions therein provided, the

      The Certificates are issuable only as registered Certificates without
coupons in denominations 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

                                Series 2005-CB1

      This Certificate is one of a duly authorized issue of Certificates
designated as C-BASS Mortgage Loan Asset-Backed Certificates, Series 2005-CB1
(herein collectively called the "Certificates"), and representing a beneficial
ownership interest in the Trust created by the Agreement.

      The Certificateholder, by its acceptance of this Certificate, agrees
that it will look solely to the funds on deposit in the Distribution Account
for payment hereunder and that the Trustee is not liable to the
Certificateholders for any amount payable under this Certificate or the
Agreement or, except as expressly provided in the Agreement, subject to any
liability under the Agreement.

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

      Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business
on the applicable Record Date in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to
be distributed to Holders of Certificates of the Class to which this
Certificate belongs on such Distribution Date pursuant to the Agreement.

      Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or, upon the request of a Certificateholder owning
Regular Certificates of a Class having Denominations aggregating at least
$5,000,000, by wire transfer or otherwise, as set forth in the Agreement. The
final distribution on each Certificate will be made in like manner, but only
upon presentment and surrender of such Certificate at the office or agency of
the Trustee specified in the notice to Certificateholders of such final
distribution.

      The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any
time by the Depositor, the Seller, the Servicer and the Trustee with the
consent of Holders of the requisite percentage of the Percentage Interests of
each Class of Certificates affected by such amendment, as specified 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 therefor or in lieu hereof whether or not notation of such consent is
made upon

                                      5
<PAGE>

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 office or agency maintained by the Trustee in New York, New York
accompanied by a written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by the holder hereof or
such holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest in the Trust will be issued to the
designated transferee or transferees.

      The Certificates are issuable only as registered Certificates without
coupons in denominations 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 and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

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

      On any Distribution Date following the date at which the Pool Balance is
equal to or less than 10% of the Pool Balance as of the Cut-off Date, the
Servicer (or one of its Affiliates) may purchase, in whole, from the Trust the
Mortgage Loans at a purchase price determined as provided in the Agreement. In
the event that no such optional termination occurs, the obligations and
responsibilities created by the Agreement will terminate upon the earlier of
(i) the Distribution Date on which the Certificate Principal Balance of each
Class of Certificates has been reduced to zero and (ii) the final payment or
other liquidation of the last Mortgage Loan in the Trust. In no event,
however, will the trust created by the Agreement continue beyond the
expiration of 21 years from the death of the last survivor of the descendants
living at the date of the Agreement of a certain person named in the
Agreement.

      Capitalized terms used herein that are defined in the Agreement shall
have the meanings ascribed to them in the Agreement, and nothing herein shall
be deemed inconsistent with that meaning.

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 office or agency maintained by the Trustee in New York, New York
accompanied by a written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by the holder hereof or
such holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest in the Trust will be issued to the
designated transferee or transferees.

      The Certificates are issuable only as registered Certificates without
coupons in denominations 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 and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

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

      On any Distribution Date following the date at which the Pool Balance is
equal to or less than 10% of the Pool Balance as of the Cut-off Date, the
Servicer (or one of its Affiliates) may purchase, in whole, from the Trust the
Mortgage Loans at a purchase price determined as provided in the Agreement. In
the event that no such optional termination occurs, the obligations and
responsibilities created by the Agreement will terminate upon the earlier of
(i) the Distribution Date on which the Certificate Principal Balance of each
Class of Certificates has been reduced to zero and (ii) the final payment or
other liquidation of the last Mortgage Loan in the Trust. In no event,
however, will the trust created by the Agreement continue beyond the
expiration of 21 years from the death of the last survivor of the descendants
living at the date of the Agreement of a certain person named in the
Agreement.

      Capitalized terms used herein that are defined in the Agreement shall
have the meanings ascribed to them in the Agreement, and nothing herein shall

such holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest in the Trust will be issued to the
designated transferee or transferees.

      The Certificates are issuable only as registered Certificates without
coupons in denominations 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 and evidencing the same aggregate Percentage Interest, as

      No service charge will be made for any such registration of transfer or
exchange, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

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

Mortgage Loans at a purchase price determined as provided in the Agreement. In

other liquidation of the last Mortgage Loan in the Trust. In no event,
however, will the trust created by the Agreement continue beyond the

                                Series 2005-CB1

      This Certificate is one of a duly authorized issue of Certificates
designated as C-BASS Mortgage Loan Asset-Backed Certificates, Series 2005-CB1
(herein collectively called the "Certificates"), and representing a beneficial
ownership interest in the Trust created by the Agreement.

      The Certificateholder, by its acceptance of this Certificate, agrees
that it will look solely to the funds on deposit in the Distribution Account
for payment hereunder and that the Trustee is not liable to the
Certificateholders for any amount payable under this Certificate or the
Agreement or, except as expressly provided in the Agreement, subject to any
liability under the Agreement.

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

      Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business
on the applicable Record Date in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to
be distributed to Holders of Certificates of the Class to which this
Certificate belongs on such Distribution Date pursuant to the Agreement.

      Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or, upon the request of a Certificateholder owning
Regular Certificates of a Class having Denominations aggregating at least
$5,000,000, by wire transfer or otherwise, as set forth in the Agreement. The
final distribution on each Certificate will be made in like manner, but only
upon presentment and surrender of such Certificate at the office or agency of
the Trustee specified in the notice to Certificateholders of such final
distribution.

      The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any
time by the Depositor, the Seller, the Servicer and the Trustee with the
consent of Holders of the requisite percentage of the Percentage Interests of
each Class of Certificates affected by such amendment, as specified in the
Agreement. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and

                                      4
<PAGE>

upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in exchange therefor 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 office or agency maintained by the Trustee in New York, New York
accompanied by a written instrument of transfer in form satisfactory to the

such holder's attorney duly authorized in writing, and thereupon one or more
new Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest in the Trust will be issued to the
designated transferee or transferees.

      The Certificates are issuable only as registered Certificates without
coupons in denominations 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 and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

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

      On any Distribution Date following the date at which the Pool Balance is
equal to or less than 10% of the Pool Balance as of the Cut-off Date, the
Servicer (or one of its Affiliates) may purchase, in whole, from the Trust the
Mortgage Loans at a purchase price determined as provided in the Agreement. In
the event that no such optional termination occurs, the obligations and
responsibilities created by the Agreement will terminate upon the earlier of

STATE OF                )
                        ) ss.:
COUNTY OF               )

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

            1. The undersigned is the proposed Transferee of an Ownership
Interest in the [Class R and/or Class XR Certificates] (the "Certificates")
issued pursuant to the Pooling and Servicing Agreement, (the "Agreement"),
relating to the above-referenced Certificates, among Bond Securitization,
L.L.C., as depositor, Credit-Based Asset Servicing and Securitization LLC, as
seller, Litton Loan Servicing LP, as servicer, and U.S. Bank National
Association, as trustee (the "Trustee"). Capitalized terms used, but not
defined herein shall have the meanings ascribed to such terms in the
Agreement. The Transferee has authorized the undersigned to make this
affidavit on behalf of the Transferee.

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

            3. The Transferee has been advised of, and understands that (i) a
tax will be imposed on Transfers of the Certificates to Persons that are not
Permitted Transferees; (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 not a Permitted Transferee, 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 a Permitted Transferee 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 Certificates if at any
time during the taxable year of the pass-through entity a Person that is not a
Permitted Transferee 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 a Permitted Transferee 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.)

<PAGE>

            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 Certificates 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 Certificates. 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 Certificates, and in connection with any Transfer by a Person for whom the
Transferee is acting as nominee, trustee or agent, and the Transferee will not
Transfer its Ownership Interest or cause any Ownership Interest to be
Transferred to any Person that the Transferee knows is not a Permitted
Transferee. In connection with any such Transfer by the Transferee, the
Transferee agrees to deliver to the Trustee a certificate substantially in the
form set forth in this Exhibit K 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 Certificates.

            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 Certificates may be a
"noneconomic residual interest" within the meaning of proposed 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. The Transferee is not an employee benefit plan or other plan
or arrangement that is subject to ERISA or to Section 4975 of the Code, nor is
the Transferee acting on behalf of or investing plan assets of such a plan or
arrangement.
