          (K)   Originals of any assumption, consolidation or modification
               agreements relating to any of the items specified in (A) through

Depositor cannot deliver the Mortgage, Assignments of Mortgage, or assumption,

recording thereon concurrently with the execution and delivery of this Agreement
solely because of a delay caused by the public recording office where such

shall deliver or cause to be delivered to the Trustee written notice stating
that such Mortgage, Assignments of Mortgage, or assumption, consolidation or

appropriate public recording office for recordation. Thereafter, the Depositor

          With respect to any Non-MERS Mortgage Loans which are not Co-op Loans,
and as to which the related Mortgaged Property is located in Florida, the
Servicer shall cause to be recorded in the appropriate public recording office
for real property records each Assignment of Mortgage referred to in this
Section 2.01 as soon as practicable. With respect to any Non-MERS Mortgage Loans
which are not Co-op Loans as to which the related Mortgaged Property is located
outside of Florida, the Servicer shall not be obligated to cause to be recorded
the Assignment of Mortgage referred to in this Section 2.01. With respect to
Co-op Loans as to which the related dwelling unit is located in Florida, the
Servicer shall cause to be filed in the appropriate filing office the Form UCC-3
referred to in this Section 2.01 as soon as practicable. With respect to any
Co-op Loans as to which the related dwelling unit is located outside Florida,
the Servicer shall not be obligated to cause to be filed the Form UCC-3 referred
to in this Section 2.01. While each such Assignment of Mortgage or Form UCC-3 is
being recorded or filed, as applicable, the Servicer shall deliver to the
Trustee a photocopy of such document. If any such Assignment of Mortgage or Form
UCC-3 is returned unrecorded or unfiled to the Servicer because of any defect
therein, the Servicer shall cause such defect to be cured and such document to
be recorded or filed in accordance with this paragraph. The Depositor shall
deliver or cause to be delivered each such original recorded or filed Assignment
of Mortgage and intermediate assignment or Form UCC-3 to the Trustee within 270
days of the Closing Date or shall deliver to the Trustee on or before such date
an Officer's Certificate stating that such document has been delivered to the
appropriate public recording or filing office for recording or filing, but has
not been returned solely because of a delay caused by such recording or filing
office. In any event, the Depositor shall use all reasonable efforts to cause
each such document with evidence of recording or filing thereon to be delivered
to the Trustee within 300 days of the Closing Date.

          With respect to each MERS Mortgage Loan, the Trustee, at the expense
of the Depositor and at the direction and with the cooperation of the Servicer,
shall cause to be taken such actions as are necessary to cause the Trustee to be
clearly identified as the owner of each such Mortgage Loan on the records of
MERS for purposes of the system of recording transfers of beneficial ownership
of mortgages maintained by MERS.

          The ownership of each Mortgage Note, the Mortgage and the contents of
the related Mortgage File is vested in the Trustee. Neither the Depositor nor
the Servicer shall take any action inconsistent with such ownership and shall
not claim any ownership interest therein. The Depositor and the Servicer shall
respond to any third party inquiries with respect to ownership of the Mortgage
Loans by stating that


                                       47

<PAGE>

such ownership is held by the Trustee on behalf of the Certificateholders.
Mortgage documents relating to the Mortgage Loans not delivered to the Trustee
are and shall be held in trust by the Servicer or any Sub-Servicer, for the
benefit of the Trustee as the owner thereof, and the Servicer's or such
Sub-Servicer's possession of the contents of each Mortgage File so retained is
for the sole purpose of servicing the related Mortgage Loan, and such retention
and possession by the Servicer or such Sub-Servicer is in a custodial capacity
only. The Depositor agrees to take no action inconsistent with the Trustee's
ownership of the Mortgage Loans, to promptly indicate to all inquiring parties
that the Mortgage Loans have been sold and to claim no ownership interest in the
Mortgage Loans. Each Mortgage File and the mortgage documents relating to the
Mortgage Loans contain proprietary business information of the Servicer and its
customers. The Trustee and the Depositor agree that they will not use such
information for business purposes without the express written consent of the
Servicer and that all such information shall be kept strictly confidential.

          It is the intention of this Agreement that the conveyance of the
Depositor's right, title and interest in and to the Trust Fund pursuant to this
Agreement shall constitute a purchase and sale and not a loan. If a conveyance
of Mortgage Loans from any Seller to the Depositor is characterized as a pledge
and not a sale, then the Depositor shall be deemed to have transferred to the
Trustee all of the Depositor's right, title and interest in, to and under the
obligations of such Seller deemed to be secured by said pledge; and it is the
intention of this Agreement that the Depositor shall also be deemed to have
granted to the Trustee a first priority security interest in all of the
Depositor's right, title, and interest in, to and under the obligations of such
Seller to the Depositor deemed to be secured by said pledge and that the Trustee
shall be deemed to be an independent custodian for purposes of perfection of the
security interest granted to the Depositor. If the conveyance of the Mortgage
Loans from the Depositor to the Trustee is characterized as a pledge, it is the
intention of this Agreement that this Agreement shall constitute a security
agreement under applicable law, and that the Depositor shall be deemed to have
granted to the Trustee a first priority security interest in all of the
Depositor's right, title and interest in, to and under the Mortgage Loans, all
payments of principal of or interest on such Mortgage Loans, all other rights
relating to and payments made in respect of the Trust Fund, and all proceeds of
any thereof. If the trust created by this Agreement terminates prior to the
satisfaction of the claims of any Person in any Certificates, the security
interest created hereby shall continue in full force and effect and the Trustee
shall be deemed to be the collateral agent for the benefit of such Person.

          In addition to the conveyance made in the first paragraph of this
Section 2.01, the Depositor does hereby convey, assign and set over to the
Trustee all of its right, title and interest in that portion of the Trust Fund
described in items (ii), (iii), (iv) and (v) of the definition thereof and
further assigns to the Trustee for the benefit of the Certificateholders those
representations and warranties of the Sellers contained in the Sale Agreements
and described in Section 3.01 hereof and the benefit of the repurchase
obligations of the Sellers described in Sections 2.02 and 3.01 hereof and the
obligations of the Sellers contained in the Sale Agreements to take, at the
request of the Depositor or the Trustee, all action on its part which is
reasonably necessary to ensure the enforceability of a Mortgage Loan.

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

          Section 2.02 Acceptance by Trustee. Except as set forth in the
Exception Report delivered contemporaneously herewith (the "Exception Report"),
the Trustee acknowledges receipt by the


                                       48

<PAGE>

Custodian on the Trustee's behalf of the Mortgage Note for each Mortgage Loan
and delivery of a Mortgage File (but does not acknowledge receipt of all
documents required to be included in such Mortgage File) with respect to each
Mortgage Loan and declares that the Custodian holds and will hold on the
Trustee's behalf such documents and any other documents constituting a part of
the Mortgage Files delivered to it in trust for the use and benefit of all
present and future Certificateholders. The Depositor will cause the Relevant
Seller to repurchase any Mortgage Loans to which an exception was taken in the
Exception Report unless such exception is cured to the satisfaction of the
Trustee within 45 Business Days of the Closing Date. The Trustee may accept
delivery of such Mortgage Files by the Custodian on its behalf. The Custodian
will deliver a copy of the Exception Report to the Depositor and the Trustee

          The Custodian, on the Trustee's behalf, agrees, for the benefit of
Certificateholders, to review each Mortgage File delivered to it within 270 days
after the Closing Date to ascertain that all documents required by Section 2.01
have been executed and received, and that such documents relate to the Mortgage
Loans identified in Exhibit A that have been conveyed to it. If the Custodian on
the Trustee's behalf finds any document or documents constituting a part of a
Mortgage File to be missing or defective (that is, mutilated, damaged, defaced
or unexecuted) in any material respect, the Custodian on the Trustee's behalf
shall promptly (and in any event within no more than five Business Days) after
such finding so notify the Servicer, the Relevant Seller, the Trustee and the
Depositor. In addition, the Custodian on the Trustee's behalf shall also notify
the Servicer, the Relevant Seller, the Trustee and the Depositor, if (a) in
examining the Mortgage Files, the documentation shows on its face (i) any
adverse claim, lien or encumbrance, (ii) that any Mortgage Note was overdue or
had been dishonored, (iii) any evidence on the face of any Mortgage Note or
Mortgage of any security interest or other right or interest therein, or (iv)
any defense against or claim to the Mortgage Note by any party or (b) the
original Mortgage with evidence of recording thereon with respect to a Mortgage
Loan is not received within 270 days of the Closing Date; provided, however,
that if the Depositor cannot deliver the original Mortgage with evidence of
recording thereon because of a delay caused by the public recording office where
such Mortgage has been delivered for recordation, the Depositor shall deliver or
cause to be delivered to the Custodian and the Trustee written notice stating
that such Mortgage has been delivered to the appropriate public recording
officer for recordation and thereafter the Depositor shall deliver or cause to
be delivered such Mortgage with evidence of recording thereon upon receipt
thereof from the public recording office. The Depositor shall request that the
Relevant Seller correct or cure such omission, defect or other irregularity, or
substitute a Mortgage Loan pursuant to the provisions of Section 3.03, within 60
days from the date the Relevant Seller was notified of such omission or defect
and, if the Relevant Seller does not correct or cure such omission or defect
within such period, that the Relevant Seller purchase such Mortgage Loan from
the Trustee within 90 days from the date the Depositor notified the Relevant
Seller and the Trustee of such omission, defect or other irregularity at the
Purchase Price of such Mortgage Loan. The Purchase Price for any Mortgage Loan
purchased pursuant to this Section 2.02 shall be paid to the Servicer and
deposited by the Servicer in the Collection Account promptly upon receipt, and,
upon receipt by the Trustee of written notification of such deposit signed by a
Servicing Officer, the Trustee shall promptly release to the Relevant Seller the
related Mortgage File and the Trustee shall execute and deliver such instruments
of transfer or assignment, without recourse, as shall be necessary to vest in
the Relevant Seller or its designee, as the case may be, any Mortgage Loan
released pursuant hereto, and the Trustee shall have no further responsibility
with regard to such Mortgage Loan. It is understood and agreed that the
obligation of the Relevant Seller to purchase, cure or substitute any Mortgage
Loan as to which a material defect in or omission of a constituent document
exists shall constitute the sole remedy respecting such defect or omission
available to the Trustee on behalf of Certificateholders. The Trustee shall be
under no duty or obligation to inspect, review and examine such documents,
instruments, certificates or other papers to determine that they are genuine,
enforceable or appropriate to the represented purpose, or that they have
actually been recorded, or that they are other than what they purport to be on
their face. The Trustee shall keep confidential the name of each Mortgagor and
shall not solicit any such Mortgagor for the purpose of refinancing the related
Mortgage Loan.

          Within 280 days of the Closing Date, the Trustee based solely on
information provided to it by the Custodian shall deliver to the Depositor and
the Servicer the Trustee's Certification, substantially in the form of Exhibit G
attached hereto, setting forth the status of the Mortgage Files as of such date.

          Section 2.03 Trust Fund; Authentication of Certificates. The Trustee
acknowledges and accepts the assignment to it of the Trust Fund created pursuant
to this Agreement in trust for the use and benefit of all present and future
Certificateholders. The Trustee acknowledges the assignment to it for the
benefit of the Trust Fund of the Mortgage Loans and has caused to be
authenticated and delivered to or upon the order of the Depositor, in exchange
for the Mortgage Loans, Certificates duly authenticated by the Trustee or, if an
Authenticating Agent has been appointed pursuant to Section 4.06, the
Authenticating Agent in authorized denominations evidencing ownership of the
entire Trust Fund.

          Section 2.04 REMIC Elections.

          (a) The Depositor hereby instructs and authorizes the Paying Agent to
make appropriate elections to treat the Trust Fund as comprising three REMICs
(the Lower-Tier REMIC, the Middle-Tier REMIC and the Upper-Tier REMIC). This
Agreement shall be construed so as to carry out the intention of the parties
that each REMIC created hereunder be treated as a REMIC at all times prior to
the date on which the Trust Fund is terminated. The Closing Date is hereby
designated as the "startup day" of each REMIC created hereunder within the
meaning of Section 860G(a)(9) of the Code. The Lower-Tier REMIC shall hold as
assets all property of the Trust Fund other than (i) the Lower-Tier REMIC
Interests and the Middle-Tier REMIC Interests and (ii) the Yield Maintenance
Agreements and the Reserve Fund. Each of the Lower-Tier REMIC Regular Interests
is hereby designated a "regular interest" (within the meaning of Section
860G(a)(1) of the Code) in the Lower-Tier REMIC. The Middle-Tier REMIC shall
hold as assets the several classes of uncertificated Lower-Tier REMIC Regular
Interests. Each of the Middle-Tier REMIC Regular Interests is hereby designated
a "regular interest" (within the meaning of Section 860G(a)(1) of the Code) in
the Middle-Tier REMIC. The Upper-Tier REMIC shall hold as assets the several
classes of uncertificated Middle-Tier REMIC Regular Interests. Each of the
Upper-Tier REMIC Regular Interests is hereby designated as a "regular interest"
(within the meaning of Section 860G(a)(1) of the Code) in the Upper-Tier REMIC.
The Class LT-R Interest is hereby designated as the sole residual interest
(within the meaning of Section 860G(a)(2) of the Code) in the Lower-Tier REMIC.
The Class MT-R Interest is hereby designated as the sole residual interest
(within the meaning of Section 860G(a)(2) of the Code) in the Middle-Tier REMIC.
The Residual Interest is hereby designated as the sole residual interest (within
the meaning of Section 860G(a)(2) of the Code) in the Upper-Tier REMIC. The
Class A-R Certificate evidences ownership of the Class LT-R Interest, the Class
MT-R Interest and the Residual Interest. All interests described in this Section
2.04(a) shall be designated as such on the Startup Day.

</TABLE>

(1)   The Class LT-R Interest shall represent the sole class of residual interest
     in the Lower-Tier REMIC. The Class LT-R Interest will not have a principal
     amount or an interest rate. The Class LT-R Interest shall be represented by
     the Class A-R Certificate.

(2)   The Class LT1A-X Interest is an interest only interest, has no principal
     balance, is not entitled to payments of principal and will bear interest on
     its notional amount. The notional amount of the Class LT1A-X Interest shall
     equal the Class 1-AX Notional Amount.

(3)   The Class LT2A-X Interest is an interest only interest, has no principal
     balance, is not entitled to payments of principal and will bear interest on
     its notional amount. The notional amount of the Class LT2A-X Interest shall
     equal the Class 2-AX Notional Amount.

(4)   The initial principal amount of the Class LT1-A Interest shall equal 1% of
     the Group One Subordinated Amount as of the first Distribution Date.

(5)   The initial principal amount of each Lower-Tier REMIC Interest ending with
     the designation "B" shall equal the excess of (i) the initial Group One
     Non-PO Allocated Amount (in the case of the Class LT1-B Interest) or the
     initial Group Two Non-PO Allocated Amount (in the case of the Class LT2-B
     Interest) over (ii) the initial principal amount of the Lower-Tier REMIC
     Interest ending with the designation "A" that is related to the same
     Mortgage Group.

(6)   The initial principal amount of the Class LT2-A Interest shall equal 1% of
     the Group Two Subordinated Amount as of the first Distribution Date.

          Interest shall be payable to, and shortfalls and losses are allocable
to, the Class LT1-AX Interest as such amounts are payable or allocable to the
Class 1-AX Certificates. Interest shall be payable to, and shortfalls and losses
are allocable to, the Class LT2-AX Interest as such amounts are payable or
allocable to the Class 2-AX Certificates.

          Principal shall be payable to, and shortfalls, losses, prepayments and
increases in principal amount related to Subsequent Recoveries are allocable to,
the Class LTA-P Component One Interest as such amounts are payable or allocable
to Class A-P Component One. Principal shall be payable to, and shortfalls,
losses, prepayments and increases in principal amount related to Subsequent
Recoveries are allocable to, the Class LTA-P Component Two Interest as such
amounts are payable or allocable to Class A-P Component Two.

          After the foregoing allocations and distributions are made to the
Class LT1-AX Interest, Class LT2-AX Interest, the Class LTA-P Component One
Interest and the Class LTA-P Component Two Interest, distributions shall be
deemed to be made and Realized Losses shall be deemed to be allocated to the
other Lower-Tier REMIC Regular Interests first, so as to keep the Uncertificated
Principal Balance of each Lower-Tier REMIC Regular Interest ending with the
designation "A" equal to 1% of the excess of (x) the Group One Non-PO Allocated
Amount (in the case of the Class LT1-A Interest) or the Group Two Non-PO
Allocated Amount (in the case of the Class LT2-A Interest) over (y) the
aggregate class principal amounts of the Class 1-A Certificates (in the case of
the Class LT1-A Interest) or the Class 2-A Certificates (in the case of the
Class LT2-A Interest) (except that if 1% of any such excess is greater than the
principal amount of the corresponding Lower-Tier REMIC Regular Interest ending
with the designation "A", the least amount of principal and Realized Losses
shall be distributed and allocated to such Lower-Tier REMIC Regular Interests
such that the Lower-Tier REMIC Subordinated Balance Ratio is maintained); and
second, any remaining principal and Realized Losses to the Lower-Tier REMIC
Regular Interests ending with the designation "B" in such a manner that the
remaining principal balance of each such Lower-Tier REMIC Regular Interest
equals the excess of (x) the Group One Non-PO Allocated Amount (in the case of
the Class LT1-B Interest) or the Group Two Non-PO Allocated Amount (in the case
of the Class LT2-B Interest) over (y) the Uncertificated Principal Balance of
the Lower-Tier REMIC Regular Interest ending with the designation "A" which is
related to the same Mortgage Group. All computations with respect to the
Lower-Tier REMIC Interests shall be taken out to eight decimal places.

          If on any Distribution Date there is an increase in the principal
amount of any Class of Certificates (other than the Class A-P Certificates)
related to Subsequent Recoveries, then, prior to distributions of principal and
allocations of losses on such Distribution Date with respect to the Lower-Tier
REMIC, there shall be a corresponding increase in the Uncertificated Principal
Balance of the Lower-Tier REMIC Regular Interests, with such increase allocated
among the Lower-Tier REMIC Regular Interests first, to each Lower-Tier REMIC
Regular Interest ending with the designation "A", so that the Uncertificated
Principal Balance of each such Lower-Tier REMIC Regular Interest continues to
equal the same percentage of the excess of (x) the Group One Non-PO Allocated
Amount (in the case of the Class LT1-A Interest) or the Group Two Non-PO
Allocated Amount (in the case of the Class LT2-A Interest) over (y) the
aggregate class principal amounts of the Class 1-A Certificates (in the case of
the Class LT1-A Interest) or the Class 2-A Certificates (in the case of the
Class LT2-A Interest) and so that the Lower-Tier REMIC Subordinated Balance
Ratio is maintained; and second, any remaining increase allocated to the
Lower-Tier REMIC Regular Interests ending with the designation "B" in such a
manner that the principal balance of each such Lower-Tier REMIC Regular Interest
equals the excess of (x) the Group One Non-PO Allocated Amount (in the case of
the Class LT1-B Interest) or the Group Two Non-PO Allocated Amount (in the case
of the Class LT2-B Interest) over (y) the Uncertificated Principal Balance of
the Lower-Tier REMIC Regular Interest ending with the designation "A" which is
related to the same Mortgage Group.

----------
(1)   The Class MT-R Interest shall represent the sole class of residual interest
     in the Middle-Tier REMIC. The Class MT-R Interest will not have a principal
     amount or an interest rate. The Class MT-R Interest shall be represented by
     the Class A-R Certificate.


                                       54

<PAGE>

     MT-R Interest shall be represented by the Class A-R Certificate.

(2)   The initial principal amount of each of these interests shall be equal to
     the Original Certificate Principal Balance the Class of corresponding
     Certificates (disregarding the notional amount of any class of
     "interest-only" certificates).

(3)   The Class MT1-AX Interest is an interest only interest, has no principal
     balance, is not entitled to payments of principal and will bear interest on
     its notional amount. The notional amount of the Class MT1-AX Interest shall
     equal the Class 1-AX Notional Amount.

(4)   The Class MT2-AX Interest is an interest only interest, has no principal
     balance, is not entitled to payments of principal and will bear interest on
     its notional amount. The notional amount of the Class MT2-AX Interest shall
     equal the Class 2-AX Notional Amount.

(5)   For any Distribution Date, the interest rate for the Class MTA-M Interest,
     Class MTM-1 Interest, Class MTB-1 Interest, Class MTB-2 Interest, Class
     MTB-3 Interest, Class MTB-4 Interest and Class MTB-5 Interest shall be a
     per annum rate equal to the weighted average of the interest rates on the
     Class LT1-A Interest and the Class LT2-A Interest weighted on the basis of
     their principal amounts immediately prior to such Distribution Date.

Principal and interest (disregarding payments in respect of Basis Risk Shortfall
Carryover Amounts) shall be payable to, and shortfalls, losses, prepayments and
increases in principal amount are allocable to, the Middle-Tier REMIC Regular
Interests as such amounts are payable and allocable to the corresponding
certificates under this Agreement (excluding Section 6.01(I)(a)(v) hereof).

          (b) Solely for the purposes of Section 1.860G-1(a)(4)(iii) of the
Treasury Regulations, the "latest possible maturity date" of each "regular
interest" in each REMIC created hereunder is the Distribution Date immediately
following the latest scheduled maturity of any Mortgage Loan.

          (c) The "tax matters person" with respect to each REMIC created
hereunder for purposes of the REMIC Provisions shall be the beneficial owner of
the Class A-R Certificate having the largest Percentage Interest of such Class;
provided, however, that such largest beneficial owner and, to the extent
relevant, each other Holder of a Class A-R Certificate, by its acceptance
thereof, irrevocably appoints the Servicer as its agent and attorney-in-fact to
act as "tax matters person" with respect to each REMIC created hereunder for
purposes of the REMIC provisions.

          (d) It is intended that each REMIC created hereunder shall constitute,
and that the affairs of the Trust Fund shall be conducted so as to qualify each
REMIC created hereunder as, a "real estate mortgage investment conduit" as
defined in and in accordance with the REMIC Provisions. In furtherance of such
intention, the Servicer covenants and agrees that it shall act as agent (and the
Servicer is hereby appointed to act as agent) on behalf of the Trust Fund, each
REMIC created hereunder and the Holder of the Class A-R Certificate and that in
such capacity it shall:

                     (i) prepare and file, or cause to be prepared and filed, in
          a timely manner, a U.S. Real Estate Mortgage Investment Conduit Income

          and file or cause to be prepared and filed with the Internal Revenue
          Service and applicable state or local tax authorities income tax or
          information returns for each taxable year with respect to each REMIC
          created hereunder, using the calendar year as the taxable year and the
          accrual method of accounting, containing such information and at the
          times and in the manner as may be required by the Code or state or
          local tax laws, regulations, or rules, and shall furnish or cause to
          be furnished to Certificateholders the schedules, statements or
          information at such times and in such manner as may be required
          thereby;


                                       55

          or as otherwise may be required by the Code, the name, title, address,
          and telephone number of the person that the Holders of the
          Certificates may contact for tax information relating thereto (and the
          Servicer shall act as the representative of the Trust Fund for this
          purpose), together with such additional information as may be required
          by such Form, and shall update such information at the time or times
          in the manner required by the Code;

                    (iii) make or cause to be made an election, on behalf of
          each REMIC created hereunder, to be treated as a REMIC, and make the
          appropriate designations, if applicable, in accordance with this
          Section 2.04 on the federal tax return of each REMIC hereunder for its
          first taxable year (and, if necessary, under applicable state law);

                    (iv) prepare and forward, or cause to be prepared and
          forwarded, to the Certificateholders and to the Internal Revenue
          Service and, if necessary, state tax authorities, all information

          Provisions, including without limitation, the calculation of any
          original issue discount;

                    (v) provide information necessary for the computation of tax

          which a Disqualified Organization is the record holder of an interest
          (the reasonable cost of computing and furnishing such information may
          be charged to the Person liable for such tax);

                    (vi) ensure that federal, state or local income tax or
          information returns shall be signed by the Trustee or such other
          Person as may be required to sign such returns by the Code or state or
          local laws, regulations or rules; and

Trustee, hereby appoints the Institution Trust Services Department of Chase to
perform the duties enumerated in (d) above.

          (f) It is intended that the rights of each Class of the Class 1-A10
and Class 2-A8 Certificates to receive payments in respect of Basis Risk
Shortfall Carryover Amounts shall be treated as a right in interest rate cap
contracts and such shall be accounted for as property held separate and apart

Class 1-A10 and Class 2-A8 Certificates. This provision is intended to satisfy
the requirements of Treasury Regulations Section 1.860G-2(i) for the treatment
of property rights coupled with REMIC interests to be separately respected and

                                   ARTICLE III

               REPRESENTATIONS AND WARRANTIES OF THE DEPOSITOR AND
                   THE SERVICER; REPURCHASE OF MORTGAGE LOANS

          Section 3.01 Representations and Warranties of the Depositor with
respect to the Mortgage Loans.

          The Depositor hereby represents and warrants to the Trustee for the
benefit of the Certificateholders that on or before the Closing Date it has
entered into the Sale Agreements with the Sellers, that the Sellers have made
the following representations and warranties with respect to each Mortgage Loan
in the Relevant Sale Agreement as of the Closing Date, which representations and
warranties run to and are for the benefit of the Depositor and the Trustee for
the benefit of the Certificateholders, and as to which the Depositor has
assigned to the Trustee for the benefit of the Certificateholders, pursuant to
Section 2.01 hereof, the right to cause the Relevant Seller to repurchase a
Mortgage Loan as to which there has occurred an uncured breach of
representations and warranties in accordance with the provisions of the Relevant
Sale Agreement.

          (a) The information set forth in the Mortgage Loan Schedule is
complete, true and correct in all material respects;

          (b) With respect to a Mortgage Loan which is not a Co-op Loan, the
Mortgage creates a first lien or a first priority ownership interest in an
estate in fee simple in real property securing the related Mortgage Note. With
respect to a Co-op Loan, the related Mortgage is a valid, enforceable and
subsisting first security interest on the related cooperative shares securing
the related Mortgage Note, subject only to (a) liens of the related residential
cooperative housing corporation for unpaid assessments representing the
Mortgagor's pro rata share of the related residential cooperative housing
corporation's payments for its blanket mortgage, current and future real
property taxes, insurance premiums, maintenance fees and other assessments to
which like collateral is commonly subject and (b) other matters to which like
collateral is commonly subject which do not materially interfere with the
benefits of the security intended to be provided by the related security
agreement. There are no liens against or security interest in the cooperative
shares relating to each Co-op Loan (except for unpaid maintenance, assessments
and other amounts owed to the related cooperative which individually or in the
aggregate will not have a material adverse effect on such Co-op Loan), which
have priority over the Trustee's security interest in such cooperative shares;

          (c) All payments due prior to the Cut-off Date for such Mortgage Loan
have been made as of the Closing Date, the Mortgage Loan is not delinquent in
payment more than 30 days and has not been dishonored; to the best of the
Relevant Seller's knowledge, there are no material defaults under the terms of
the Mortgage Loan; the Relevant Seller has not advanced funds, or induced,
solicited or knowingly received any advance of funds from a party other than the
owner of the Mortgaged Property subject to the Mortgage (or, with respect to a
Co-op Loan, the related Mortgagor), directly or indirectly, for the payment of
any amount required by the Mortgage Loan; there has been no more than one
delinquency in excess of 30 days during the preceding twelve-month period;


                                       57

<PAGE>

          (d) To the best of the Relevant Seller's knowledge, all taxes,
governmental assessments, insurance premiums, water, sewer and municipal
charges, leasehold payments or ground rents which previously became due and
owing have been paid, or escrow funds have been established in an amount
sufficient to pay for every such escrowed item which remains unpaid and which
has been assessed but is not yet due and payable;

          (e) The terms of the Mortgage Note and the Mortgage have not been
impaired, waived, altered or modified in any respect, except by written
instruments. No Mortgagor has been released, in whole or in part, from the terms
thereof except in connection with an assumption agreement and which assumption
agreement is part of the Mortgage File and the terms of which are reflected in
the Mortgage Loan Schedule;

          (f) The Mortgage Note and the Mortgage are not subject to any right of
rescission, set-off, counterclaim or defense, including, without limitation, the
defense of usury, nor will the operation of any of the terms of the Mortgage
Note or Mortgage, or the exercise of any right thereunder, render the Mortgage
Note or Mortgage unenforceable, in whole or in part, or subject to any right of
rescission, set-off, counterclaim or defense, including the defense of usury,
and no such right of rescission, set-off, counterclaim or defense has been
asserted with respect thereto, and the Mortgagor was not a debtor in any state
or federal bankruptcy or insolvency proceeding at the time the Mortgage Loan was
originated;

          (g) With respect to a Mortgage Loan which is not a Co-op Loan, all
buildings or other customarily insured improvements upon the Mortgaged Property
are insured by an insurer acceptable under the FNMA Guides against loss by fire,
hazards of extended coverage and such other hazards as are provided for in the
FNMA Guides or by FHLMC. All such standard hazard policies are in full force and
effect and on the date of origination contained a standard mortgagee clause
naming the Relevant Seller and its successors in interest and assigns as loss
payee and such clause is still in effect and all premiums due thereon have been
paid. If required by the Flood Disaster Protection Act of 1973, as amended, the
Mortgaged Property is covered by a flood insurance policy meeting the
requirements of the current guidelines of the Federal Insurance Administration
which policy conforms to FNMA and FHLMC requirements. The Mortgage obligates the
Mortgagor thereunder to maintain all such insurance at the Mortgagor's cost and
expense, and on the Mortgagor's failure to do so, authorizes the holder of the
Mortgage to maintain such insurance at the Mortgagor's cost and expense and to
seek reimbursement therefor from the Mortgagor;

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

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

          (j) With respect to a Mortgage Loan which is not a Co-op Loan, the
Mortgage is a valid, subsisting, enforceable and perfected first lien on the
Mortgaged Property, including, all buildings on the Mortgaged Property. The
Mortgage and the Mortgage Note do not contain any evidence of any security
interest or other interest or right thereto. Such lien is free and clear of all
adverse claims, liens and encumbrances having priority over the first lien of
the Mortgage subject only to (1) the lien of non-delinquent current real
property taxes and assessments not yet due and payable, (2) covenants,
conditions and restrictions, rights of way, easements and other matters of the
public record as of the date of recording


                                       58

<PAGE>

which are acceptable to mortgage lending institutions generally and either (A)
which are referred to or otherwise considered in the appraisal made for the
originator of the Mortgage Loan, or (B) which do not adversely affect the
Appraised Value of the Mortgaged Property as set forth in such appraisal, and
(3) other matters to which like properties are commonly subject which do not
materially interfere with the benefits of the security intended to be provided
by the Mortgage or the use, enjoyment, value or marketability of the related
Mortgaged Property. Any security agreement, chattel mortgage or equivalent
document related to and delivered in connection with the Mortgage Loan
establishes and creates a valid, subsisting, enforceable and perfected first
lien and first priority security interest on the property described therein, and
the Depositor has the full right to sell and assign the same to the Trustee for
the benefit of the Certificateholders;

          (k) The Mortgage Note and the related Mortgage are original and
genuine and each is the legal, valid and binding obligation of the maker
thereof, enforceable in all respects in accordance with its terms subject to
bankruptcy, insolvency and other laws of general application affecting the
rights of creditors and the Depositor has taken all action necessary to transfer
such rights of enforceability to the Trustee for the benefit of the
Certificateholders. All parties to the Mortgage Note and the Mortgage had the
legal capacity to enter into the Mortgage Loan and to execute and deliver the
Mortgage Note and the Mortgage. The Mortgage Note and the Mortgage have been
duly and property executed by such parties. The proceeds of the Mortgage Loan
have been fully disbursed and there is no requirement for future advances
thereunder, and any and all requirements as to completion of any on-site or
off-site improvements and as to disbursements of any escrow funds therefor have
been complied with;

          (l) The Relevant Seller is the sole owner and holder of the Mortgage
Loan and the indebtedness evidenced by the Mortgage Note, except for the
Assignments of Mortgage which have been sent for recording, and upon recordation
the Relevant Seller will be the owner of record of the Mortgage and the
indebtedness evidenced by the Mortgage Note, and upon the sale of the Mortgage
Loan to the Trust for the benefit of the Certificateholders, the Relevant Seller
will retain the Mortgage File or any part thereof with respect thereto not
delivered to the Trust for the benefit of the Certificateholders or its designee
in trust only for the purpose of servicing and supervising the servicing of the
Mortgage Loan. Immediately prior to the transfer and assignment to the Trust for
the benefit of the Certificateholders, the Mortgage Loan, including the Mortgage
Note and the Mortgage, were not subject to an assignment or pledge, and the
Depositor had good and marketable title to and was the sole owner thereof and
had full right to transfer and sell the Mortgage Loan to the Trustee for the
benefit of the Certificateholders free and clear of any encumbrance, equity,
lien, pledge, charge, claim or security interest and has the full right and
authority subject to no interest or participation of, or agreement with, any
other party, to sell and assign the Mortgage Loan pursuant to this Agreement and
following the sale of the Mortgage Loan, the Trustee for the benefit of the
Certificateholders will own such Mortgage Loan free and clear of any
encumbrance, equity, participation interest, lien, pledge, charge, claim or
security interest;

          (m) With respect to a Mortgage Loan which is not a Co-op Loan, the
Mortgage Loan is covered by an ALTA lender's title insurance policy or other
generally acceptable form of policy or insurance acceptable to FNMA or FHLMC,
issued by a title insurer acceptable to FNMA or FHLMC and qualified to do
business in the jurisdiction where the Mortgaged Property is located, insuring
(subject to the exceptions contained in (j) (1), (2) and (3) above) the Relevant
Seller, its successors and assigns, as to the first priority lien of the
Mortgage in the original principal amount of the Mortgage Loan. Such lender's
title insurance policy insures ingress and egress by or upon the Mortgaged
Property or any interest therein. Where required by state law or regulation, the
Mortgagor has been given the opportunity to choose the carrier of the required
mortgage title insurance. The Relevant Seller, its successors and assigns, are
the sole insureds of such lender's title insurance policy, and such lender's
title insurance policy is in full force and effect and will be in full force and
effect upon the consummation of the transactions contemplated by this Agreement.
No claims have been made under such lender's title


                                       59

<PAGE>

insurance policy, and no prior holder of the related Mortgage, including the
Relevant Seller, has done, by act or omission, anything which would impair the
coverage of such lender's title insurance policy;

          (n) There is no default, breach, violation or event of acceleration
existent, under the Mortgage or the related Mortgage Note and no event which,
with the passage of time or with notice and the expiration of any grace or cure
period, would constitute a default, breach, violation or event permitting
acceleration; and neither the Relevant Seller nor any prior mortgagee has waived
any default, breach, violation or event permitting acceleration;

          (o) There are no mechanics', or similar liens or claims which have
been filed for work, labor or material (and no rights are outstanding that under
law could give rise to such liens) affecting the related Mortgaged Property (or
the related residential dwelling unit in the Underlying Mortgage Property, in
the case of a Co-op Loan) which are or may be liens prior to or equal to the
lien of the related Mortgage;

          (p) With respect to a Mortgage Loan which is not a Co-op Loan, all
improvements subject to the Mortgage which were considered in determining the
Appraised Value of the Mortgaged Property lie wholly within the boundaries and
building restriction lines of the Mortgaged Property (and wholly within the
project with respect to a condominium unit) and no improvements on adjoining
properties encroach upon the Mortgaged Property except those which are insured
against by the title insurance policy referred to in clause (m) above and all
improvements on the property comply with all applicable zoning and subdivision
laws and ordinances; the Mortgaged Property is lawfully occupied under
applicable law;

          (q) The Mortgage Loan complies in all material respects with all the
terms, conditions and requirements of the Relevant Seller's underwriting
standards in effect at the time of origination of such Mortgage Loan. The
Mortgage Notes and Mortgages (exclusive of any riders) are on forms generally
acceptable to FNMA or FHLMC. Monthly Payments under the Mortgage Note are due
and payable on the first day of each month. The Mortgage contains the usual and
enforceable provisions of the originator at the time of origination for the
acceleration of the payment of the unpaid principal amount of the Mortgage Loan
if the related Mortgaged Property is sold without the prior consent of the
mortgagee thereunder;

          (r) The Mortgaged Property (or Underlying Mortgaged Property, in the
case of a Co-op Loan), is not subject to any material damage by waste, fire,
earthquake, windstorm, flood or other casualty. To the best of the Relevant
Seller's knowledge, at origination of the Mortgage Loan there was, and there
currently is, no proceeding pending for the total or partial condemnation of the
Mortgaged Property (or Underlying Mortgaged Property, in the case of a Co-op
Loan);

          (s) The related Mortgage contains customary and enforceable provisions
such as to render the rights and remedies of the holder thereof adequate for the
realization against the Mortgaged Property of the benefits of the security
provided thereby, including, (l) in the case of a Mortgage designated as a deed
of trust, by trustee's sale, and (2) otherwise by judicial foreclosure. There is
no homestead or other exemption available to the Mortgagor which would interfere
with the right to sell the Mortgaged Property at a trustee's sale or the right
to foreclose the Mortgage subject to applicable federal and state laws and
judicial precedent with respect to bankruptcy and right of redemption or similar
law;

          (t) If the Mortgage constitutes a deed of trust, a trustee, authorized
and duly qualified if required under applicable law to act as such, has been
properly designated and currently so serves and is named in the Mortgage, and no
fees or expenses, except as may be required by local law, are or will become
payable by the Purchaser to the trustee under the deed of trust, except in
connection with a trustee's sale or attempted sale after default by the
Mortgagor;


                                       60

<PAGE>

          (u) The Mortgage File contains an appraisal or a recertification
document (in the case of a Mortgage Loan originated under CHF's Streamlined
Refinance Program) of the related Mortgaged Property (or the related residential
dwelling unit in the Underlying Mortgaged Property, in the case of a Co-op
Loan), signed prior to the final approval of the mortgage loan application by an
appraiser approved by the Relevant Seller who had no interest, direct or
indirect, in the Mortgaged Property (or Underlying Mortgaged Property, in the
case of a Co-op Loan), or in any loan made on the security thereof, and whose
compensation is not affected by the approval or disapproval of the Mortgage
Loan. The appraisal is in a form acceptable to FNMA or FHLMC;

          (v) All parties which have had any interest in the Mortgage, whether
as mortgagee, assignee, pledgee or otherwise, are (or, during the period in
which they held and disposed of such interest, were) (A) in substantial
compliance with any and all applicable licensing requirements of the laws of the
state wherein the Mortgaged Property (or Underlying Mortgaged Property, in the
case of a Co-op Loan), is located, and (B) (1) organized under the laws of such
state, or (2) qualified to do business in such state, or (3) federal savings and
loan associations or national banks or a Federal Home Loan Bank or savings bank
having principal offices in such state, or (4) not doing business in such state;

          (w) The related Mortgage Note is not and has not been secured by any
collateral except the lien of the corresponding Mortgage and the security
interest of any applicable security interest of any applicable agreement or
chattel mortgage referred to above and such collateral does not serve as
security for any other obligation;

          (x) The Mortgagor has received all disclosure materials required by
applicable law with respect to the making of such mortgage loans;

          (y) The Mortgage Loan does not contain "graduated payment" features;

          (z) The Mortgagor is not in bankruptcy and, to the best of the
Relevant Seller's knowledge, the Mortgagor is not insolvent;

          (aa) The Mortgage Loans are fixed rate mortgage loans. Each Mortgage
Loan has an original term to maturity of not more than thirty (30) years with
interest payable in arrears on the first day of each month. No Mortgage Loan
contains terms or provisions which would result in negative amortization;

          (bb) Each Mortgage Note, each Mortgage, each Assignment of Mortgage
and any other documents required pursuant to this Agreement to be delivered to
the Trustee on behalf of the Certificateholders or its designee, or its assignee
for each Mortgage Loan, have been, on or before the Closing Date, delivered to
the Trustee on behalf of the Certificateholders or its designee, or its
assignee;

          (cc) All escrow payments have been collected in full compliance with
state and federal law and the provisions of the related Mortgage Note and
Mortgage. As to any Mortgage Loan that is the subject of an escrow, escrow of
funds is not prohibited by applicable law and has been established in an amount
sufficient to pay for every escrowed item that remains unpaid and has been
assessed but is not yet due and payable. No escrow deposits or other charges or
payments due under the Mortgage Note have been capitalized under any Mortgage or
the related Mortgage Note. Any interest required to be paid pursuant to state,
federal and local law has been properly paid and credited;

          (dd) [Reserved];

          (ee) In the event that at origination the Mortgage Loan has a
Loan-to-Value Ratio greater than 80%, the excess of the principal balance of the
Mortgage Loan over 75% of the Appraised Value of the


                                       61

<PAGE>

Mortgaged Property, with respect to a refinanced Mortgage Loan, or the lesser of
the Appraised Value or the purchase price of the Mortgaged Property (or
Underlying Mortgaged Property, in the case of a Co-op Loan), with respect to a
purchase money Mortgage Loan, is and will be insured as to payment defaults by a
Primary Insurance Policy issued by a Qualified Insurer, except where the primary
mortgage insurance was (i) impermissible at origination at applicable law, in
which case such Mortgage Loan was originated in accordance with applicable law,
(ii) cancelled at the request of the Mortgagor pursuant to the cancellation
requirements of FNMA, FHLMC, state law or, as applicable the Home Owner and
Equity Protection Act of 1994, as amended, or (iii) automatically terminated in
accordance with the termination requirements of FNMA, FHLMC, state law or, as
applicable the Home Owner and Equity Protection Act of 1994, as amended. All
provisions of such Primary Insurance Policy have been and are being complied
with, such policy is in full force and effect, and all premiums due thereunder
have been paid. No action, inaction, or event has occurred and no state of facts
exists that has, or will result in the exclusion from, denial of, or defense to
coverage. Any Mortgage Loan subject to a Primary Insurance Policy obligates the
Mortgagor thereunder to maintain the Primary Insurance Policy and to pay all
premiums and charges in connection therewith. The Mortgage Rate for the Mortgage
Loan as set forth on the Mortgage Loan Schedule is net of any such insurance
premium;

          (ff) The Assignment of Mortgage is in recordable form and is
acceptable for recording (or, in the case of a Co-op Loan, is in a form
acceptable for filing) under the laws of the jurisdiction in which the Mortgaged
Property (or underlying Mortgaged Property, in the case of a Co-op Loan) is
located;

          (gg) As to Mortgage Loans that are not secured by an interest in a
leasehold estate, the Mortgaged Property (or Underlying Mortgaged Property, in
the case of a Co-op Loan), is located in the state identified in the Mortgage
Loan Schedule and consists of a single parcel of real property with a detached
single family residence erected thereon, or a two-to four-family dwelling, or an
individual condominium unit in a condominium project, or a dwelling unit in a
residential cooperative housing corporation or an individual unit in an attached
planned unit development or a detached planned unit development, provided,
however, that no residence or dwelling is a single parcel of real property with

          (ll) No action has been taken or failed to be taken by Depositor, on
or prior to the Closing Date, which has resulted or will result in an exclusion
from, denial of, or defense to coverage under any Primary Insurance Policy
(including, without limitation, any exclusions, denials or defenses which would
limit or reduce the availability of the timely payment of the full amount of the
loss otherwise due thereunder to the insured) whether arising out of actions,
representations, errors, omissions, negligence, or fraud of the Depositor, or
for any other reason under such coverage;

          (mm) The Mortgage Loan was originated by a mortgagee approved by the

          (oo) As of the Closing Date, the Mortgage Loan is a "qualified
mortgage" within the meaning of Section 860G(a)(3) of the Code (without regard
to Treasury Regulations Section 1.860G-2(f) or any similar rule that provides
that a defective obligation is a qualified mortgage for a temporary period);

          (pp) With respect to a Mortgage Loan that is a Co-op Loan, the stock

          (qq) As of the Closing Date, the Mortgage Loan is not the subject of

          (rr) As of the Closing Date, the Mortgage Loan does not provide for
interest other than at either (i) a single fixed rate in effect throughout the

lending laws nor is any Mortgage Loan a "High Cost Loan" or "Covered Loan," as
applicable (as such terms are defined in the current Standard & Poor's LEVELS(R)

                                       63

<PAGE>

October 1, 2002 through March 6, 2003 is governed by the Georgia Fair Lending
Act of 2002, as amended; and

          (uu) As to each Mortgage Loan that is secured by an interest in a

          Upon discovery by any of the Depositor, the Servicer or the Trustee of
a breach of any of the foregoing representations and warranties which materially
and adversely affects the value of a Mortgage Loan or the interest of the
Certificateholders (or which materially and adversely affects the interests of
the Certificateholders in the related Mortgage Loan in the case of a
representation and warranty relating to a particular Mortgage Loan), the party
discovering such breach shall give prompt written notice to the other parties
and to the Relevant Seller, which notice shall specify the date of discovery.
Pursuant to the Relevant Sale Agreement, the Relevant Seller shall within 90
days from the earlier of (i) the date of receipt of notice of such breach or
(ii) the date the Relevant Seller otherwise discovers such breach, cure such
breach, substitute a Mortgage Loan pursuant to the provisions of Section 3.03
or, if the breach relates to a particular Mortgage Loan, purchase such Mortgage
Loan from the Trustee at the Purchase Price. The Purchase Price for the
purchased Mortgage Loan shall be paid to the Servicer and shall be deposited by
the Servicer in the Collection Account promptly upon receipt, and, upon receipt
by the Trustee of written notification of such deposit signed by a Servicing
Officer, the Trustee shall promptly release to the Relevant Seller the related
Mortgage File, and the Trustee shall execute and deliver such instruments of
transfer or assignment as may be provided to it by the Servicer, without
recourse, as shall be necessary to vest in the Relevant Seller or its designee,
as the case may be, any Mortgage Loan released pursuant hereto, and the Trustee
shall have no further responsibility with regard to such Mortgage Loan. It is
understood and agreed that the obligation of the Relevant Seller to cure,
substitute or purchase any Mortgage Loan as to which such a breach has occurred
shall constitute the sole remedy respecting such breach available to
Certificateholders or the Trustee on behalf of Certificateholder.

          Section 3.02 Representations and Warranties of the Servicer. The
Servicer represents and warrants to, and covenants with, the Trustee for the
benefit of the Certificateholders that as of the Closing Date:

          (a) The Servicer is a limited liability company duly chartered and
validly existing in good standing under the laws of the State of Delaware, and
the Servicer is duly qualified or registered as a foreign corporation in good
standing in each jurisdiction in which the ownership or lease or its properties
or the conduct of its business requires such qualification;

          (b) The execution and delivery of this Agreement by the Servicer and
its performance and compliance with the terms of this Agreement will not violate
the Servicer's certificate of formation or by-laws or constitute a default (or
an event which, with notice or lapse of time, or both, would constitute a
default) under, or result in the breach of, any material contract, agreement or
other instrument to which the Servicer is a party or which may be applicable to
the Servicer or any of its assets;

          (c) This Agreement, assuming due authorization, execution and delivery
by the Trustee and the Depositor, constitutes a valid, legal and binding
obligation of the Servicer, enforceable against it in accordance with the terms
hereof subject to applicable bankruptcy, insolvency, reorganization, moratorium
and other laws affecting the enforcement of creditors' rights generally and to
general


                                       64

<PAGE>

principles of equity, regardless of whether such enforcement is considered in a
proceeding in equity or at law;

          (d) The Servicer is not in default with respect to any order or decree
of any court or any order, regulation or demand of any federal, state, municipal
or governmental agency, which default might have consequences that would
materially and adversely affect the condition (financial or other) or operations
of the Servicer or its properties or might have consequences that would affect
its performance hereunder; and

          (e) No litigation is pending or, to the best of the Servicer's
knowledge, threatened against the Servicer which would prohibit its entering
into this Agreement or performing its obligations under this Agreement. It is
understood and agreed that the representations and warranties set forth in this
Section 3.02 shall survive the issuance and delivery of the Certificates and
shall be continuing as long as any Certificate shall be outstanding or this
Agreement has been terminated.

          Section 3.03 Option to Substitute. If either of the Sellers is
required to repurchase any Mortgage Loan pursuant to Section 2.02 or 3.01, that
Seller may, at its option, within two years from the Closing Date, remove such
defective Mortgage Loan from the terms of this Agreement and substitute another
mortgage loan for such defective Mortgage Loan, in lieu of repurchasing such
defective Mortgage Loan. Any substitute Mortgage Loan shall (a) have a Principal
Balance at the time of substitution not in excess of the Principal Balance of
the removed Mortgage Loan (the amount of any difference, plus one month's
interest thereon at the Mortgage Rate borne by the removed Mortgage Loan, being
paid by the Relevant Seller and deemed to be a Principal Prepayment to be
deposited by the Servicer in the Collection Account), (b) have a Mortgage Rate
not less than, and not more than one percentage point greater than, the Mortgage
Rate of the removed Mortgage Loan (provided, however, that if the Mortgage Rate
on the substitute Mortgage Loan exceeds the Mortgage Rate on the removed
Mortgage Loan, the amount of that excess interest (the "Substitute Excess
Interest") shall be payable to the Class A-R Certificate), (c) have a remaining
term to stated maturity not later than, and not more than one year less than,
the remaining term to stated maturity of the removed Mortgage Loan, (d) be, in
the reasonable determination of the Servicer, of the same type, quality and
character (including location of the Mortgaged Property (or underlying Mortgaged
Property, in the case of a Co-op Loan)) as the removed Mortgage Loan as if the
breach had not occurred, (e) have a Loan-to-Value Ratio at origination no
greater than that of the removed Mortgage Loan and (f) be, in the reasonable
determination of the Relevant Seller, in material compliance with the
representations and warranties contained in the Sale Agreement and described in
Section 3.01, as of the date of substitution.

          The Relevant Seller shall amend the Mortgage Loan Schedule to reflect
the withdrawal of the removed Mortgage Loan from this Agreement and the
substitution of such substitute Mortgage Loan therefor and shall send a copy of
such amended Mortgage Loan Schedule to the Servicer and the Trustee. The Sale
Agreements provide that upon such amendment the Relevant Seller shall be deemed
to have made as to such substitute Mortgage Loan the representations and
warranties set forth in Section 3.01 as of the date of such substitution, which
shall be continuing as long as any Certificate shall be outstanding or this
Agreement has not been terminated, and the remedies for breach of any such
representation or warranty shall be as set forth in Section 3.01. Upon such
amendment, the Custodian on behalf of the Trustee shall review the Mortgage File
delivered to it relating to the substitute Mortgage Loan, within the time and in
the manner and with the remedies specified in Section 2.02, except that for
purposes of this Section 3.03 (other than the two-year period specified in the
first sentence of this Section), such time shall be measured from the date of
the applicable substitution. In the event of such a substitution, accrued
interest on the substitute Mortgage Loan for the month in which the substitution
occurs and any Principal Prepayments made thereon during such month shall be the
property of the Trust Fund, and accrued interest for such month on the Mortgage
Loan for which the substitution is made and any Principal


                                       65

<PAGE>

Prepayments made thereon during such month shall be the property of the Relevant
Seller. The principal payment on a substitute Mortgage Loan due on the Due Date
in the month of substitution shall be the property of the Seller, and the
principal payment on the Mortgage Loan for which the substitution is made due on
such date shall be the property of the Trust Fund.

Depository for registration and receipt by the Trustee or, if a Paying Agent has
been appointed under Section 4.05, the Paying Agent, of an adequate supply of
certificates from the Depositor, the Trustee or if the Paying Agent is appointed
under Section 4.05, the Paying Agent shall issue the Definitive Certificates
based on information received from the Depository. Neither the Depositor, the
Servicer, the Paying Agent nor 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.

officers of the Depositor shall bind the Depositor, notwithstanding that such
individuals or any of them have ceased to be an officer prior to the
authentication and delivery of such Certificate or did not hold such offices at
the date of such Certificates. No Certificate shall be entitled to any benefit
under this Agreement, or be valid for any purpose, unless there appears on such
Certificate a manual authentication by an officer of the Trustee (or if an
Authenticating Agent has been appointed pursuant to Section 4.06, the
Authenticating Agent) 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.

          Section 4.02 Registration of Transfer and Exchange of Certificates.

          (a) The Trustee or, if a Paying Agent has been appointed under Section
4.05, the Paying Agent, shall cause to be kept a certificate register (the
"Certificate Register") in which, subject to such reasonable regulations as it
may prescribe, the Trustee or, if a Paying Agent has been appointed under
Section 4.05, the Paying Agent, shall provide for the registration of
Certificates and of transfers and exchanges of Certificates as herein provided.

          (b) Upon surrender for registration of transfer of any Certificate at
any office or agency of the Trustee, or if a Paying Agent has been appointed
hereunder pursuant to Section 4.05, the Paying Agent maintained for such
purpose, the Depositor shall execute and the Trustee or if an Authenticating
Agent is appointed under Section 4.06, the Authenticating Agent shall
authenticate and deliver, in the


                                        68

name of the designated transferee or transferees, a Certificate of a like Class
and aggregate Percentage Interest and dated the date of authentication by the
Authenticating Agent.

          (c) No transfer of a Class B-3, Class B-4 or Class B-5 Certificate
shall be made unless such transfer is made pursuant to an effective registration
statement or otherwise in accordance with the requirements under the Securities
Act. If such a transfer is to be made in reliance upon an exemption from said
Act, (i) the Depositor may require (except with respect to the initial transfer
of a Class B-3, Class B-4 or Class B-5 Certificate from J.P. Morgan Securities
Inc. and except if the transferee executes a certificate substantially in the
form of Exhibit H hereto) a written opinion of independent counsel acceptable to
and in form and substance reasonably satisfactory to the Depositor and the
Trustee that such transfer may be made pursuant to an exemption, describing the
applicable exemption and the basis therefor, from said Act and laws or is being
made pursuant to said Act and laws, which opinion of counsel shall not be an
expense of the Trust Fund, the Trustee, the Depositor or the Servicer, and (ii)
the Depositor shall require the transferee to execute a certification
substantially in the form of Exhibit H or Exhibit I.

          (d) (i) No transfer of an ERISA Restricted Certificate or a Class A-R
Certificate shall be made unless the prospective transferee provides the
Depositor and the Trustee with (I) a representation as set forth in Exhibit K
for Class A-R Certificates or in Exhibit M for ERISA Restricted Certificates to
the effect that such transferee is not an employee benefit plan subject to Title
I of ERISA, a plan subject to Section 4975 of the Code or a plan or arrangement
subject to any provisions under any federal, state, local, non-U.S. or other
laws or regulations that are substantively similar to the foregoing provisions
of ERISA or the Code ("Similar Law") (collectively, a "Plan"), and is not
directly or indirectly acquiring the Certificate for, on behalf of or with any
assets of any such Plan, or (II) solely in the case of an ERISA Restricted
Certificate, (A) if the Certificate has been the subject of an ERISA-Qualifying
Underwriting, a representation as set forth in Exhibit M that such transferee is
an insurance company that is acquiring the ERISA-Restricted Certificate with
assets contained in an "insurance company general account," as defined in
Section V(E) of Prohibited Transaction Class Exemption ("PTCE") 95-60, and the
acquisition and holding of the Certificate are covered and exempt under Sections
I and III of PTCE 95-60, or (B) solely in the case of a Definitive Certificate,
an Opinion of Counsel reasonably satisfactory to the Depositor and the Trustee
to the effect that the acquisition and holding of such Certificate will not
constitute or result in a nonexempt prohibited transaction under ERISA or the
Code, or a violation of Similar Law, and will not subject the Depositor, the
Servicer or the Trustee to any obligation in addition to those expressly
undertaken in this Agreement, which Opinion of Counsel shall not be an expense
of the Depositor, the Servicer or the Trustee.

               (ii) Except in the case of a Definitive Certificate, the
representations set forth in paragraph (i) of this Subsection 4.02(d), other
than subparagraph (i)(II)(B), shall be deemed to have been made to the Depositor
and the Trustee by the transferee's acceptance of an ERISA Restricted
Certificate or a Class A-R Certificate (or the acceptance by a Certificate Owner
of the beneficial interest in any Class of ERISA Restricted Certificates or a
Class A-R Certificate). Notwithstanding any other provision herein to the
contrary, any purported transfer of an ERISA Restricted Certificate or a Class
A-R Certificate to or on behalf of a Plan without the delivery to the Depositor
of a representation or an Opinion of Counsel reasonably satisfactory to the
Depositor and the Trustee as described above shall be void and of no effect.
None of the Depositor, the Servicer or the Trustee shall be under any liability
to any Person for any registration or transfer of any ERISA Restricted
Certificate or Class A-R Certificate that is in fact not permitted by this
Section 4.02(d) nor shall the Paying Agent be under any liability for making any
payments due on such 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 transfer was registered in accordance with the foregoing
requirements. The Depositor, Servicer, Paying Agent and/or Trustee shall be
entitled, but not obligated, to recover from any Holder of any ERISA Restricted
Certificate or Class A-R Certificate


                                        69

<PAGE>

that was in fact a Plan and that held such Certificate in violation of this
Section 4.02(d) all payments made on such ERISA Restricted Certificate or Class
A-R Certificate at and after the time it commenced such holding. Any such
payments so recovered shall be paid and delivered to the last preceding Holder
of such Certificate that is not a Plan.

          (e) At the option of a Certificateholder, a Certificate may be
exchanged for another Certificate or Certificates of authorized denominations of
a like Class, upon surrender of the Certificate to be exchanged at any office or
agency of the Trustee, or if a Paying Agent has been appointed under Section
4.05, the Paying Agent, maintained for such purpose. Whenever the Certificate is
so surrendered for exchange, the Depositor shall execute and the Authenticating
Agent shall authenticate and deliver, the Certificate which the
Certificateholder making the exchange is entitled to receive. Every Certificate
presented or surrendered for transfer or exchange shall (if so required by the
Authenticating Agent) be duly endorsed by, or be accompanied by a written
instrument of transfer in the form satisfactory to the Authenticating Agent duly
executed by, the Holder thereof or his attorney duly authorized in writing.

          (f) No service charge shall be made to the Holder for any transfer or
exchange of a Certificate, but the Servicer may require payment by the
Certificateholders of a sum sufficient to cover any tax or governmental charge
that may be imposed in connection with any transfer or exchange of such
Certificate.

          (g) All Certificates surrendered for transfer or exchange shall be
destroyed by the Trustee or if a Paying Agent has been appointed under Section
4.05, the Paying Agent, in accordance with the Trustee's or, if a Paying Agent
has been appointed under Section 4.05, the Paying Agent's, standard procedures.

          (h) [Reserved].

          (i) A Disqualified Organization is prohibited from acquiring
beneficial ownership of a Class A-R Certificate. Notwithstanding anything to the
contrary contained herein, (i) unless and until the Servicer and the Trustee
shall have received an Opinion of Counsel, satisfactory to it in form and
substance, to the effect that the absence of the conditions contained in this
Section 4.02(i) would not result in the imposition of federal tax upon any REMIC
created hereunder or cause any REMIC created hereunder to fail to qualify as a
REMIC, no transfer, sale or other disposition of the Class A-R Certificate
(including for purposes of this section any beneficial interest therein) may be
made without the express written consent of the Certificate Registrar or, if no
Certificate Registrar is appointed, the Trustee, which consent is to be granted
by the Certificate Registrar or, if no Certificate Registrar is appointed, the
Trustee only upon compliance with the requirements of this Section and (ii) no
transfer, sale or other disposition of the Class A-R Certificate (or any
beneficial interest therein) may be made to a Person who is not a U.S. Person
unless such Person furnishes the transferor, the Certificate Registrar and the
Trustee, with a duly completed and effective Form W-8ECI (or any successor
thereto) or an Opinion of Counsel to the effect that such transfer is in
accordance with the requirements of the Code and that the transfer will not be
disregarded for federal income tax purposes. As a condition to granting its
consent to a transfer of a Class A-R Certificate, the Certificate Registrar or,
if no Certificate Registrar is appointed, the Trustee, shall require the
proposed transferee of such Certificate (including, in the case of the initial
issuance of the Class A-R Certificate, the initial Holder thereof) to execute a
letter and affidavit substantially in the form attached hereto as Exhibit K and
shall require the proposed transferor (other than in the case of the transfer to
the initial Holder) of such Certificate to execute a letter substantially in the
form attached hereto as Exhibit K-1. In the absence of a contrary instruction
from the transferor of such Certificate, declaration (11) in the affidavit in
Exhibit K may be left blank. If the transferor requests by written notice to the
Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee,
prior to the date of the proposed transfer that one of the two other forms of
declaration (11) of such affidavit be used, then the


                                       70

<PAGE>

Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee,
shall require that such form of declaration (11) be included in such affidavit.

          As a condition to the granting of the consent referred to in this
Section 4.02(i), prior to the transfer, sale, pledge, hypothecation or other
disposition of the Class A-R Certificate or any interest therein, the
Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee
shall require that (1) the proposed transferee deliver to the Trustee or
Certificate Registrar, as applicable, its taxpayer identification number and
state, under penalties of perjury that such number is the social security or
employer identification number, as the case may be, of the transferee or provide
an affidavit under penalties of perjury stating that as of the date of such
transfer such transferee is not and has no intention of becoming a Disqualified
Organization; (2) the proposed transferee deliver to the Trustee or Certificate
Registrar, as applicable, an affidavit stating (i) that such transferee is not
acquiring such Class A-R Certificate as an agent, broker, nominee, or middleman
for a Disqualified Organization, (ii) if the Class A-R Certificate is a
"non-economic residual interest" within the meaning of Treas. Reg. Section
1.860E-1(c)(2), (X) that no purpose of the acquisition of the Class A-R
Certificate is to avoid or impede the assessment or collection of tax, (Y) that
such transferee has historically paid its debts as they came due and will
continue to pay its debts as they come due, and (Z) that such transferee
represents that it understands that, as the holder of the non-economic residual
interest, the transferee may incur tax liabilities in excess of any cash flows
generated by the interest and that the transferee intends to pay taxes
associated with holding the residual interest, and (iii) unless the Certificate
Registrar or, if no Certificate Registrar is appointed, the Trustee consents to
the transfer of the Class A-R Certificate to a Person who is not a U.S. Person
and who has furnished either a duly completed and effective Form W-8ECI (or any
successor thereto) or an Opinion of Counsel to the effect that the transfer will
not be disregarded for federal income tax purposes, that it is a U.S. Person;
(3) if so requested by the transferor in written notice provided to the
Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee,
prior to the date of the proposed transfer, the proposed transferee deliver to
the Trustee or Certificate Registrar, as applicable, an affidavit that includes
a declaration made in the form of declaration (11) in the affidavit set forth in
Exhibit K requested by the transferor; and (4) the transferor deliver to the
Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee
a written certification that as of the date of such transfer it has no knowledge
and no reason to know that the affirmations described in clauses (1), (2) and
(3) were false. The Certificate Registrar or, if no Certificate Registrar is
appointed, the Trustee shall not grant the consent referred to in this Section
4.02(i) if it has actual knowledge that any statement made in the affidavit
issued pursuant to the preceding sentence is not true. Notwithstanding any
purported transfer, sale or other disposition of the Class A-R Certificate to a
Disqualified Organization or in violation of the provisions of this Section
4.02(i), such transfer, sale or other disposition shall be deemed to be of no
legal force or effect whatsoever and such Disqualified Organization shall not be
deemed to be a Class A-R Certificateholder for any purpose hereunder, including,
but not limited to, the receipt of distributions on such Class A-R Certificate.
If any purported transfer shall be in violation of the provisions of this
Section 4.02(i) then the prior Holder of the Class A-R Certificate shall, upon
discovery that the transfer of such Class A-R Certificate was not in fact
permitted by this Section 4.02(i), be restored to all rights and obligations as
a Holder thereof retroactive to the date of the purported transfer of such Class
A-R Certificate. The Trustee, the Servicer and the Certificate Registrar shall
be under no liability to any Person for any registration or transfer of a Class
A-R Certificate that is not permitted by this Section 4.02(i) or for making
payments due on such Class A-R Certificate to the purported Holder thereof or
taking any other action with respect to such purported Holder under the
provisions of this Agreement so long as the transfer was not registered under
the written certification of the Certificate Registrar or, if no Certificate
Registrar is appointed, the Trustee as described in this Section 4.02(i). The
prior Holder shall be entitled to recover from any purported Holder of a Class
A-R Certificate that was in fact not a permitted purported transferee under this
Section 4.02(i) at the time it became a purported Holder all payments made to
such purported Holder on such Class A-R Certificate; provided that the Servicer
shall not be responsible for such recovery. Each Class A-R Certificateholder, by
the acceptance of the Class A-R Certificate, shall be


                                       71

<PAGE>

deemed for all purposes to have consented to the provisions of this Section
4.02(i) and to any amendment to this Agreement deemed necessary by counsel of
the Trustee or the Servicer to ensure that the Class A-R Certificate is not
transferred to a Disqualified Organization and that any transfer of such Class
A-R Certificate will not cause the imposition of a tax upon any REMIC created
hereunder or cause any REMIC created hereunder to fail to qualify as a REMIC.
The restrictions on transfer of the Class A-R Certificate will cease to apply
and be void upon receipt by the Certificate Registrar or, if no Certificate
Registrar is appointed, the Trustee of an Opinion of Counsel to the effect that
such restrictions on transfer are no longer necessary to avoid the risk of
material federal taxation to any REMIC created hereunder or prevent any REMIC
created hereunder from qualifying as a REMIC.

          (j) The Servicer shall make available upon written request to each
Holder and each proposed transferee of a Class B-3, Class B-4 or Class B-5
Certificate such information as may be required to permit the proposed transfer
to be effected pursuant to Rule 144A under the Securities Act.

          Section 4.03 Mutilated, Destroyed, Lost or Stolen Certificates. If (a)
any mutilated Certificate is surrendered to the Trustee or, if a Paying Agent
has been appointed under Section 4.05, the Paying Agent, or the Trustee or, if a
Paying Agent has been appointed under Section 4.05, the Paying Agent, receives
evidence to its satisfaction of the destruction, loss or theft of any
Certificate, and (b) there is delivered to the Trustee or, if a Paying Agent has
been appointed under Section 4.05, the Paying Agent, such security or indemnity
as may be required by it to save it harmless, then, in the absence of notice to
the Trustee or, if a Paying Agent has been appointed under Section 4.05, the
Paying Agent, that such Certificate has been acquired by a bona fide purchaser,
the Trustee or, if a Paying Agent has been appointed under Section 4.05, the
Paying Agent, 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 Class. Upon the issuance of any new Certificate under this Section,
the Trustee or, if a Paying Agent has been appointed under Section 4.05, the
Paying Agent, may require of the Certificateholder the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses connected therewith. Any replacement
Certificate of any Class issued pursuant to this Section shall constitute
complete and indefeasible evidence of ownership of the Percentage Interest in
the distributions to which the Certificateholders of such Class are entitled, as
if originally issued, whether or not the mutilated, destroyed, lost or stolen
Certificate shall be found at any time, and such mutilated, destroyed, lost or
stolen Certificate shall be of no force or effect under this Agreement, to the
extent permitted by law.

          Section 4.04 Persons Deemed Owners. Prior to due presentation of a
Certificate of any Class for registration of transfer, the Depositor, the
Servicer, the Paying Agent and the Trustee may treat the Person in whose name
any Certificate is registered on the Record Date as the owner of such
Certificate and the Percentage Interest in the distributions to which the
Certificateholders of such Class are entitled on the relevant date as the Holder
of such Certificate and the Percentage Interest represented by such Certificate
for the purpose of receiving remittances pursuant to Section 6.01 and for all
other purposes whatsoever, and neither the Depositor, the Servicer, the Paying
Agent nor the Trustee shall be affected by notice to the contrary.

          Section 4.05 Appointment of Paying Agent and Certificate Registrar;
Certificate Account. The Trustee shall appoint a Paying Agent and a Certificate
Registrar (the "Certificate Registrar") hereunder, provided such Paying Agent
and such Certificate Registrar shall not be the Depositor, any Seller, or an
Affiliate of the Depositor or any Seller unless such Paying Agent or such
Certificate Registrar is the World Securities Services Department of Chase. No
later than two Business Days prior to each Distribution Date, the Servicer shall
deposit or cause to be deposited with the Paying Agent from funds on deposit in
the Collection Account a sum up to the Available Distribution Amount, such sum
to be held in trust for the benefit of Certificateholders in a segregated
account (the "Certificate Account")


                                        72

<PAGE>

which shall be an Eligible Account in the name of "The Bank of New York, as
Trustee, in trust for and for the benefit of the Certificateholders of
Multi-Class Mortgage Pass-Through Certificates, Chase Mortgage Finance
Corporation, Series 2006-S2 - Certificate Account". The Paying Agent shall
establish such Certificate Account with a commercial bank, a savings bank or a
savings and loan association. The Paying Agent may invest moneys in the
Certificate Account in Eligible Investments, which shall mature not later than a
date sufficient to make payment on the Distribution Date next following the date
of such investment and shall not be sold or disposed of prior to maturity. All
income and gain realized from any such investment shall be for the benefit of
the Paying Agent as additional compensation and shall be subject to its
withdrawal or order from time to time. The amount of any losses incurred in
respect of any such investments (to the extent not offset by income from other
such investments) shall be deposited in the Certificate Account by the Paying
Agent out of its own funds immediately as realized. The Servicer shall cause the
Paying Agent to perform each of the obligations of the Paying Agent set forth
herein and shall be liable to the Trustee and the Certificateholders for failure
of the Paying Agent to perform such obligations. So long as the Paying Agent is
a party other than the Trustee, the Trustee shall have no liability in
connection with the performance or failure of performance of the Paying Agent.
The Trustee designates the World Securities Services Department of Chase as the
initial Paying Agent and initial Certificate Registrar. Only the Trustee may
remove the Paying Agent and Certificate Registrar and may do so at will,
provided that the Trustee gives 20 days' prior written notice of such removal to
the Paying Agent and Certificate Registrar and the Rating Agencies.
Notwithstanding anything to the contrary contained herein, no approvals or
consent shall be required for the subsequent appointment of The Bank of New York
as Paying Agent.

          The Paying Agent will hold all sums held by it for the payment to
Certificateholders in trust for the benefit of the Certificateholders entitled
thereto until such sums shall be paid to such Certificateholders.

          Section 4.06 Authenticating Agents.

          (a) The Trustee may appoint one or more Authenticating Agents (each,
an "Authenticating Agent") which shall be authorized to act on behalf of the
Trustee in authenticating the Certificates. Wherever reference is made in this
Agreement to the authentication of Certificates by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication on behalf of the Trustee by an Authenticating Agent and a
certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent must be an entity organized and
doing business under the laws of the United States of America or of any state,
having a combined capital and surplus of at least $15,000,000, authorized under
such laws to do a trust business and subject to supervision or examination by
federal or state authorities. So long as the Authenticating Agent is a party
other than the Trustee, the Trustee shall have no liability in connection with
the performance or failure of performance of the Authenticating Agent. The
Trustee hereby appoints the Paying Agent as the initial Authenticating Agent.

          (b) Any Person into which any Authenticating Agent may be merged or
converted or with which it may be consolidated, or any Person resulting from any
merger, conversion or consolidation to which any Authenticating Agent shall be a
party, or any Person succeeding to the corporate agency business of any
Authenticating Agent, shall continue to be the Authenticating Agent without the
execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent.

          (c) Any Authenticating Agent may at any time resign by giving at least
30 days' advance written notice of resignation to the Trustee and the Depositor.
The Trustee may at any time terminate the agency of any Authenticating Agent by
giving written notice of termination to such Authenticating Agent and the
Depositor. Upon receiving a notice of resignation or upon such a termination, or
in case at any


                                       73

<PAGE>

time any Authenticating Agent shall cease to be eligible in accordance within
the provisions of this Section 4.06, the Trustee may appoint a successor
Authenticating Agent, shall give written notice of such appointment to the
Depositor and shall mail notice of such appointment to all Holders of
Certificates. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers, duties
and responsibilities of its predecessor hereunder, with like effect as if
originally named as Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section 4.06. No
Authenticating Agent shall have responsibility or liability for any action taken
by it as such at the direction of the Trustee. Each of the Authenticating Agent,
Certificate Registrar and Paying Agent shall be afforded the same rights,
protections and indemnities as the Trustee as set forth under Article VIII
hereunder.

                                    ARTICLE V

                  ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

          Section 5.01 Servicer to Service Mortgage Loans. The Servicer shall
service and administer the Mortgage Loans and shall have full power and
authority, acting alone or through Sub-Servicers as provided in Section 5.02, to
do any and all things which it may deem necessary or desirable in connection
with such servicing and administration, all in accordance with Accepted
Servicing Practices. Without limiting the generality of the foregoing, the
Servicer in its own name or in the name of a Sub-Servicer shall, pursuant to a
power of attorney granted hereby by the Trustee for such purposes, when the
Servicer or the Sub-Servicer, as the case may be, believes it appropriate in its
best judgment, to execute and deliver, on behalf of the Certificateholders and
the Trustee or any of them, any and all instruments of satisfaction or
cancellation, or of partial or full release or discharge and all other
comparable instruments, with respect to the Mortgage Loans and with respect to
the related Mortgaged Properties; provided, however, that subject to the
provisions of this paragraph, the Servicer may allow a modification with respect
to a Mortgage Loan if the Servicer would tak
