Subgroup (other than the related PO Percentage thereof with respect to the
related Discount Mortgage Loans) as of the beginning of the related Due Period,
exceeds such percentage as of the Cut-off Date, then the Subgroup Senior
Prepayment Percentage with respect to the Group I Senior Certificates of each
Subgroup for such Distribution Date will equal 100%.

         Section 2.01 CONVEYANCE OF MORTGAGE LOANS TO TRUSTEE.

         (a) The Depositor concurrently with the execution and delivery of this
Agreement, sells, transfers and assigns to each Trust without recourse all its
right, title and interest in and to (i) the Mortgage Loans identified in the
Mortgage Loan Schedule, including all interest and principal due with respect to
the Mortgage Loans after the Cut-off Date, but excluding any payments of
principal and interest due on or prior to the Cut-off Date; (ii) such assets as
shall from time to time be credited or are required by the terms of this
Agreement to be credited to the Master Servicer Collection Account, (iii) such
assets relating to the Mortgage Loans as from time to time may be held by the
Servicers in the Protected Accounts, the Master Servicer in the Master Servicer
Collection Account and the Paying Agent in the Distribution Account, (iv) any
REO Property, (v) the Required Insurance Policies and any amounts paid or
payable by the insurer under any Insurance Policy (to the extent the mortgagee
has a claim thereto), (vi) the Mortgage Loan Purchase Agreement to the extent
provided in Subsection 2.03(a), (vii) the rights with respect to the Servicing
Agreements as assigned to the Trustee on behalf of the related
Certificateholders by the Assignment Agreements and (viii) all proceeds of the
foregoing. Although it is the intent of the parties to this Agreement that the
conveyance of the Depositor's right, title and interest in and to the Mortgage
Loans and other assets in the Trust Funds pursuant to this Agreement shall
constitute a purchase and sale and not a loan, in the event that such conveyance
is deemed to be a loan, it is the intent of the parties to this Agreement that
the Depositor shall be deemed to have granted to the Trustee a first priority
perfected security interest in all of the Depositor's right, title and interest
in, to and under the Mortgage Loans and other assets in the Trust Fund, and that
this Agreement shall constitute a security agreement under applicable law.
Moreover, if for any other reason this Agreement is held or deemed to create a
security interest in the Mortgage Loans and the other assets constituting the
Trust Funds, then it is intended as follows: (a) this Agreement shall also be
deemed to be a security agreement within the meaning of Articles 8 and 9 of the
Uniform Commercial Code; (b) the conveyance provided for in this Section shall
be deemed to be a grant by the Depositor to the Trustee of a security interest
in all of the Depositor's right, title and interest in and to the Mortgage Loans
and all proceeds of the conversion, voluntary or involuntary, of the foregoing
into cash, instruments, securities or other property, including without
limitation all amounts from time to time held or invested in the Distribution
Account, whether in the form of cash, instruments, securities or other property;
(c) the possession by the Trustee or its agent of the Mortgage Loans and such
other items of property as constitute instruments, money, negotiable documents
or chattel paper shall be deemed to be "possession by the secured party" for
purposes of perfecting the security interest pursuant to Section 9-305 of the
Uniform Commercial Code; (d) the Securities Administrator shall be deemed to be
the "securities intermediary," as such term is defined in Section
8-102(a)(14)(ii) of the New York Uniform Commercial Code, that in the ordinary
course of its business maintains "securities accounts" for others, as such term
is used in Section 8-501 of the New York Uniform Commercial Code; (e) the
"securities intermediary's jurisdiction" as defined in the New York Uniform
Commercial Code shall be the State of New York; (f) the Securities Administrator
is not a "clearing corporation", as such term is defined in Section 8-102(a)(5)
of the New York Uniform Commercial Code and (g) notifications to persons holding
such property, and acknowledgments, receipts or confirmations from persons
holding such property, shall be deemed to be notifications to or
acknowledgments, receipts or confirmations from, financial intermediaries,
bailees or agents (as applicable) of the Trustee for the purpose of perfecting
such security interest under applicable law. The Depositor, the Seller and the
Trustee agree that it is not intended that any Mortgage Loan be conveyed to the
Trust that is either (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 Jan 1, 2005.

hereby delivers to the Custodian, as agent for the Trustee, with respect to each
Mortgage Loan (other than a Cooperative Loan):

if clause (w) in the proviso below applies, shall be in recordable form);

                  (iii) unless the Mortgage Loan is a MOM Loan, a certified copy
of the assignment (which may be in the form of a blanket assignment if permitted
in the jurisdiction in which the Mortgaged Property is located) to "U.S. Bank
National Association, as Trustee", with evidence of recording with respect to
each Mortgage Loan in the name of the Trustee thereon (or if clause (w) in the
proviso below applies or for Mortgage Loans with respect to which the related

Counsel has been provided as set forth in this Section 2.01(b), shall be in
recordable form);

affidavit, together with a copy of the related Mortgage Note;

                  (ii) A counterpart of the Cooperative Lease and the Assignment
of Proprietary Lease to the originator of the Cooperative Loan with intervening
assignments showing an unbroken chain of title from such originator to the
Trustee;

                  (iii) The related Cooperative Stock Certificate, representing
the related Cooperative Stock pledged with respect to such Cooperative Loan,
together with an undated stock power (or other similar instrument) executed in
blank;

                  (iv) The original recognition agreement by the Cooperative of
the interests of the mortgagee with respect to the related Cooperative Loan and
any transfer documents related to the recognition agreement;

                  (v) The Security Agreement;

                  (vi) Copies of the original UCC-1 financing statement, and any
continuation statements, filed by the originator of such Cooperative Loan as
secured party, each with evidence of recording thereof, evidencing the interest
of the originator under the Security Agreement and the Assignment of Proprietary
Lease;

                  (vii) Copies of the filed UCC-3 assignments of the security
interest referenced in clause (vi) above showing an unbroken chain of title from
the originator to the Trustee, each with evidence of recording thereof,

or preferred loan agreement, if any, relating to such Cooperative Loan;
PROVIDED, HOWEVER, that in lieu of the foregoing, the Depositor may deliver to
the Custodian, as agent of the Trustee, the following documents, under the
circumstances set forth below: (w) in lieu of the original Security Instrument,
assignments to the Trustee or intervening assignments thereof which have been
delivered, are being delivered or will, upon receipt of recording information
relating to the Security Instrument required to be included thereon, be
delivered to recording offices for recording and have not been returned to the
Depositor in time to permit their delivery as specified above, the Depositor may
deliver a true copy thereof with a certification by the Depositor, on the face
of such copy, substantially as follows: "Certified to be a true and correct copy
of the original, which has been transmitted for recording"; (x) in lieu of the
Security Instrument, assignment to the Trustee or intervening assignments
thereof, if the applicable jurisdiction retains the originals of such documents
(as evidenced by a certification from the Depositor to such effect) the
Depositor may deliver photocopies of such documents containing an original
certification by the judicial or other governmental authority of the
jurisdiction where such documents were recorded; (y) in lieu of the Mortgage
Notes relating to the Mortgage Loans identified on Exhibit 5 to the Mortgage
Loan Purchase Agreement, the Depositor may deliver lost note affidavits from the
Seller; and (z) the Depositor shall not be required to deliver intervening

originator or underlying Seller and the Seller, between the Seller and the
Depositor, and between the Depositor and the Trustee; and provided, further,
however, that in the case of Mortgage Loans which have been prepaid in full
after the Cut-off Date and prior to the Closing Date, the Depositor, in lieu of
delivering the above documents, may deliver to the Trustee or the Custodian, as
its agent, a certification to such effect and shall deposit all amounts paid in
respect of such Mortgage Loans in the Master Servicer Collection Account on the
Closing Date. The Depositor shall deliver such original documents (including any
original documents as to which certified copies had previously been delivered)
to the Trustee or the Custodian, as its agent, promptly after they are received.
The Depositor shall cause the Seller, at its expense, to cause each assignment
of the Security Instrument to the Trustee to be recorded not later than 180 days
after the Closing Date, unless (a) such recordation is not required by the
Rating Agencies or an Opinion of Counsel addressed to the Trustee has been
provided to the Trustee (with a copy to the Custodian) which states that
recordation of such Security Instrument is not required to protect the interests
of the related Certificateholders in the related Mortgage Loans or (b) MERS is
identified on the Mortgage or on a properly recorded assignment of the Mortgage
as the mortgagee of record solely as nominee for the Seller and its successor
and assigns; provided, however, notwithstanding the foregoing, each assignment
shall be submitted for recording by the Seller in the manner described above, at
no expense to the Trust or the Trustee or the Custodian, as its agent, upon the
earliest to occur of: (i) reasonable direction by the Holders of Certificates
evidencing Fractional Undivided Interests aggregating not less than 25% of the
Trust Fund, (ii) the occurrence of an Event of Default, (iii) the occurrence of
a bankruptcy, insolvency or foreclosure relating to the Seller and (iv) the
occurrence of a servicing transfer as described in Section 8.02 hereof.
Notwithstanding the foregoing, if the Seller fails to pay the cost of recording
the assignments, such expense will be paid by the Trustee and the Trustee shall
be reimbursed for such expenses by the Trust in accordance with Section 9.05.

         Section 2.02 ACCEPTANCE OF MORTGAGE LOANS AND UNDERLYING CERTIFICATES
BY TRUSTEE.

         (a) The Trustee acknowledges the sale, transfer and assignment of the
Trust Funds to it by the Depositor and receipt of, subject to further review and
the exceptions which may be noted pursuant to the procedures described below,
and declares that it holds, the documents (or certified copies thereof)
delivered to the Custodian, as its agent, pursuant to Section 2.01(b), and
declares that it will continue to hold those documents and any amendments,
replacements or supplements thereto and all other assets of the Trust Funds
delivered to it as Trustee in trust for the use and benefit of all present and
future Holders of the related Certificates. On the Closing Date, the Custodian,
with respect to the Mortgage Loans, shall acknowledge with respect to each
Mortgage Loan by delivery to the Depositor and the Trustee of an Initial
Certification receipt of the Mortgage File, but without review of such Mortgage
File, except to the extent necessary to confirm that such Mortgage File contains
the related Mortgage Note or lost note affidavit. No later than 90 days after
the Closing Date (or, with respect to any Substitute Mortgage Loan, within five
Business Days after the receipt by the Trustee or Custodian thereof), the
Trustee agrees, for the benefit of the related Certificateholders, to review or
cause to be reviewed by the Custodian on its behalf (under the Custodial
Agreement), each Mortgage File delivered to it and to execute and deliver, or
cause to be executed and delivered, to the Depositor and the Trustee an Interim
Certification. In conducting such review, the Trustee or Custodian will
ascertain whether all required documents have been executed and received, and
based on the Mortgage Loan Schedule, whether those documents relate, determined
on the basis of the Mortgagor name, original principal balance and loan number,
to the Mortgage Loans it has received, as identified in the Mortgage Loan
Schedule. In performing any such review, the Trustee or the Custodian, as its
agent, may conclusively rely on the purported due execution and genuineness of
any such document and on the purported genuineness of any signature thereon. If
the Trustee or the Custodian, as its agent, finds any document constituting part
of the Mortgage File has not been executed or received, or to be unrelated,
determined on the basis of the Mortgagor name, original principal balance and
loan number, to the Mortgage Loans identified in Exhibit B or to appear
defective on its face (a "Material Defect"), the Trustee or the Custodian, as
its agent, shall promptly notify the Seller. In accordance with the Mortgage
Loan Purchase Agreement, the Seller shall correct or cure any such defect within
ninety (90) days from the date of notice from the Trustee or the Custodian, as
its agent, of the defect and if the Seller fails to correct or cure the defect
within such period, and such defect materially and adversely affects the
interests of the related Certificateholders in the related Mortgage Loan, the
Trustee shall enforce the Seller's obligation under the Mortgage Loan Purchase
Agreement to, within 90 days from the Trustee's or the Custodian's notification,
provide a Substitute Mortgage Loan (if within two years of the Closing Date) or
purchase such Mortgage Loan at the Repurchase Price; provided that, if such
defect would cause the Mortgage Loan to be other than a "qualified mortgage" as
defined in Section 860G(a)(3) of the Code, any such cure or repurchase must
occur within 90 days from the date such breach was discovered; provided,
however, that if such defect relates solely to the inability of the Seller to
deliver the original Security Instrument or intervening assignments thereof, or
a certified copy because the originals of such documents, or a certified copy
have not been returned by the applicable jurisdiction, the Seller shall not be
required to purchase such Mortgage Loan if the Seller delivers such original
documents or certified copy promptly upon receipt, but in no event later than
360 days after the Closing Date. The foregoing repurchase obligation shall not
apply in the event that the Seller cannot deliver such original or copy of any
document submitted for recording to the appropriate recording office in the
applicable jurisdiction because such document has not been returned by such
office; provided that the Seller shall instead deliver a recording receipt of
such recording office or, if such receipt is not available, a certificate
confirming that such documents have been accepted for recording, and delivery to
the Trustee or the Custodian, as its agent, shall be effected by the Seller
within thirty days of its receipt of the original recorded document.
         (b) No later than 180 days after the Closing Date, the Trustee or the
Custodian, as its agent, will review, for the benefit of the Certificateholders,
the Mortgage Files delivered to it and will execute and deliver or cause to be
executed and delivered to the Depositor and the Trustee a Final Certification.
In conducting such review, the Trustee or the Custodian, as its agent, will
ascertain whether an original of each document required to be recorded has been
returned from the recording office with evidence of recording thereon or a
certified copy has been obtained from the recording office. If the Trustee or
the Custodian, as its agent, finds a Material Defect, the Trustee or the
Custodian, as its agent, shall promptly notify the Seller (provided, however,
that with respect to those documents described in subsections (b)(I)(iv), (v),
and (vii) of Section 2.01 and subsection (b)(II)(ix) of Section 2.01, the
Trustee's and Custodian's obligations shall extend only to the documents
actually delivered to the Custodian pursuant to such subsections). In accordance
with the Mortgage Loan Purchase Agreement, the Seller shall correct or cure any
such defect within 90 days from the date of notice from the Trustee or the
Custodian, as its agent, of the Material Defect and if the Seller is unable to
cure such defect within such period, and if such defect materially and adversely
affects the interests of the related Certificateholders in the related Mortgage
Loan, the Trustee shall enforce the Seller's obligation under the Mortgage Loan
Purchase Agreement to, within 90 days from the Trustee's or Custodian's
notification, provide a Substitute Mortgage Loan (if within two years of the
Closing Date) or purchase such Mortgage Loan at the Repurchase Price, provided
that, if such defect would cause the Mortgage Loan to be other than a "qualified
mortgage" as defined in Section 860G(a)(3) of the Code, any such cure,
repurchase or substitution must occur within 90 days from the date such breach
was discovered, provided, however, that if such defect relates solely to the
inability of the Seller to deliver the original Security Instrument or
intervening assignments thereof, or a certified copy, because the originals of
such documents or a certified copy, have not been returned by the applicable
jurisdiction, the Seller shall not be required to purchase such Mortgage Loan,
if the Seller delivers such original documents or certified copy promptly upon
receipt, but in no event later than 360 days after the Closing Date. The
foregoing repurchase obligation shall not apply in the event that the Seller
cannot deliver such original or copy of any document submitted for recording to
the appropriate recording office in the applicable jurisdiction because such
document has not been returned by such office; provided that the Seller shall
instead deliver a recording receipt of such recording office or, if such receipt
is not available, a certificate confirming that such documents have been
accepted for recording, and delivery to the Trustee or the Custodian, as its
agent, shall be effected by the Seller within thirty days of its receipt of the
original recorded document.

         (c) In the event that a Mortgage Loan is purchased by the Seller in
accordance with Subsections 2.02(a) or (b) above, the Seller shall remit to the
Master Servicer the Repurchase Price for deposit in the Master Servicer
Collection Account and the Seller shall provide to the Securities Administrator
and the Trustee written notification detailing the components of the Repurchase
Price. Upon deposit of the Repurchase Price in the Master Servicer Collection
Account, the Depositor shall notify the Trustee and the Custodian, as agent of
the Trustee (upon receipt of a Request for Release in the form of Exhibit D
attached hereto with respect to such Mortgage Loan), shall release to the Seller
the related Mortgage File and the Trustee shall execute and deliver all
instruments of transfer or assignment, without recourse, representation or
warranty, furnished to it by the Seller, as are necessary to vest in the Seller
title to and rights under the Mortgage Loan. Such purchase shall be deemed to
have occurred on the date on which the Repurchase Price in immediately available
funds is received by the Paying Agent. The Master Servicer shall amend the
Mortgage Loan Schedule, which was previously delivered to it by the Depositor in
a form agreed to between the Depositor, the Master Servicer and the Trustee, to
reflect such repurchase and shall promptly notify the Rating Agencies and the
Securities Administrator of such amendment. The obligation of the Seller to
repurchase or substitute for any Mortgage Loan a Substitute Mortgage Loan as to
which such a defect in a constituent document exists shall be the sole remedy
respecting such defect available to the related Certificateholders or to the
Trustee on their behalf.

         Section 2.03 ASSIGNMENT OF INTEREST IN THE MORTGAGE LOAN PURCHASE
AGREEMENT.

         (a) The Depositor hereby assigns to the Trustee, on behalf of the
Certificateholders of the Certificates, all of its right, title and interest in
the Mortgage Loan Purchase Agreement, including but not limited to the
Depositor's rights and obligations pursuant to the Servicing Agreements (noting
that the Seller has retained the right in the event of breach of the
representations, warranties and covenants, if any, with respect to the related
Mortgage Loans of the related Servicer under the related Servicing Agreement to
enforce the provisions thereof and to seek all or any available remedies). The
obligations of the Seller to substitute or repurchase, as applicable, a Mortgage
Loan shall be the Trustee's and the related Certificateholders' sole remedy for
any breach thereof. At the request of the Trustee, the Depositor shall take such
actions as may be necessary to enforce the above right, title and interest on
behalf of the Trustee, the related Certificateholders of the Certificates shall
execute such further documents as the Trustee may reasonably require in order to
enable the Trustee to carry out such enforcement.

         (b) If the Depositor, the Securities Administrator or the Trustee
discovers a breach of any of the representations and warranties set forth in the
Mortgage Loan Purchase Agreement, which breach materially and adversely affects
the value of the interests of related Certificateholders or the Trustee in the
related Mortgage Loan, the party discovering the breach shall give prompt
written notice of the breach to the other parties. The Seller, within 90 days of
its discovery or receipt of notice that such breach has occurred (whichever
occurs earlier), shall cure the breach in all material respects or, subject to
the Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as
applicable, shall purchase the Mortgage Loan or any property acquired with
respect thereto from the Trustee; provided, however, that if there is a breach
of any representation set forth in the Mortgage Loan Purchase Agreement or
Section 2.04 of this Agreement, as applicable, and the Mortgage Loan or the
related property acquired with respect thereto has been sold, then the Seller
shall pay, in lieu of the Repurchase Price, any excess of the Repurchase Price
over the Net Liquidation Proceeds received upon such sale. If the Net
Liquidation Proceeds exceed the Repurchase Price, any excess shall be paid to
the Seller to the extent not required by law to be paid to the borrower. Any
such purchase by the Seller shall be made by providing an amount equal to the
Repurchase Price to the Master Servicer for deposit in the Master Servicer
Collection Account and written notification detailing the components of such
Repurchase Price to the Master Servicer. The Depositor shall notify the Trustee
and submit to the Custodian, as agent for the Trustee, a Request for Release,
and the Custodian shall release, or the Trustee shall cause the Custodian to
release, to the Seller the related Mortgage File and the Trustee shall execute
and deliver all instruments of transfer or assignment furnished to it by the
Seller, without recourse, representation or warranty as are necessary to vest in
the Seller title to and rights under the Mortgage Loan or any property acquired
with respect thereto. Such purchase shall be deemed to have occurred on the date
on which the Repurchase Price in available funds is received by the Trustee. The
Master Servicer shall amend the Mortgage Loan Schedule to reflect such
repurchase and shall promptly notify the Trustee and the Rating Agencies of such
amendment. Enforcement of the obligation of the Seller to purchase (or
substitute a Substitute Mortgage Loan for) any Mortgage Loan or any property
acquired with respect thereto (or pay the Repurchase Price as set forth in the
above proviso) as to which a breach has occurred and is continuing shall
constitute the sole remedy respecting such breach available to the
Certificateholders or the Trustee on their behalf.

         Section 2.04 SUBSTITUTION OF MORTGAGE LOANS.

         Notwithstanding anything to the contrary in this Agreement, in lieu of
purchasing a Mortgage Loan pursuant to the Mortgage Loan Purchase Agreement or
Sections 2.02 or 2.03 of this Agreement, the Seller may, no later than the date
by which such purchase by the Seller would otherwise be required, tender to the
Trustee a Substitute Mortgage Loan accompanied by a certificate of an authorized
officer of the Seller that such Substitute Mortgage Loan conforms to the
requirements set forth in the definition of "Substitute Mortgage Loan" in this
Agreement; provided, however, that substitution pursuant to the Mortgage Loan
Purchase Agreement or Section 2.04 of this Agreement, as applicable, in lieu of
purchase shall not be permitted after the termination of the two-year period
beginning on the Startup Day; provided, further, that if the breach would cause
the Mortgage Loan to be other than a "qualified mortgage" as defined in Section
860G(a)(3) of the Code, any such cure or substitution must occur within 90 days
from the date the breach was discovered. The Custodian, as agent for the
Trustee, shall examine the Mortgage File for any Substitute Mortgage Loan in the
manner set forth in Section 2.02(a) and the Trustee or the Custodian, as its
agent, shall notify the Seller, in writing, within five Business Days after
receipt, whether or not the documents relating to the Substitute Mortgage Loan
satisfy the requirements of the fifth sentence of Subsection 2.02(a). Within two
Business Days after such notification, the Seller shall provide to the Master
Servicer for deposit in the Master Servicer Collection Account the amount, if
any, by which the Outstanding Principal Balance as of the next preceding Due
Date of the Mortgage Loan for which substitution is being made, after giving
effect to the Scheduled Principal due on such date, exceeds the Outstanding
Principal Balance as of such date of the Substitute Mortgage Loan, after giving
effect to Scheduled Principal due on such date, which amount shall be treated
for the purposes of this Agreement as if it were the payment by the Seller of
the Repurchase Price for the purchase of a Mortgage Loan by the Seller. After
such notification to the Seller and, if any such excess exists, upon receipt of
such deposit, the Trustee shall accept such Substitute Mortgage Loan which shall
thereafter be deemed to be a Mortgage Loan hereunder. 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
Prepayments made thereon during such month shall be the property of the Seller.
The Scheduled Principal on a Substitute Mortgage Loan due on the Due Date in the
month of substitution shall be the property of the Seller and the Scheduled
Principal on the Mortgage Loan for which the substitution is made due on such
Due Date shall be the property of the Trust Fund. Upon acceptance of the
Substitute Mortgage Loan (and delivery to the Custodian of a Request for Release
for such Mortgage Loan), the Custodian, as agent for the Trustee, shall release
to the Seller the related Mortgage File related to any Mortgage Loan released
pursuant to the Mortgage Loan Purchase Agreement or Section 2.04 of this
Agreement, as applicable, and shall execute and deliver all instruments of
transfer or assignment, without recourse, representation or warranty in form as
provided to it as are necessary to vest in the Seller title to and rights under
any Mortgage Loan released pursuant to the Mortgage Loan Purchase Agreement or
Section 2.04 of this Agreement, as applicable. The Seller shall deliver to the
Custodian the documents related to the Substitute Mortgage Loan in accordance
with the provisions of the Mortgage Loan Purchase Agreement or Subsections
2.01(b) and 2.02(b) of this Agreement, as applicable, with the date of
acceptance of the Substitute Mortgage Loan deemed to be the Closing Date for
purposes of the time periods set forth in those Subsections. The representations
and warranties set forth in the Mortgage Loan Purchase Agreement shall be deemed
to have been made by the Seller with respect to each Substitute Mortgage Loan as
of the date of acceptance of such Mortgage Loan by the Trustee. The Master
Servicer shall amend the Mortgage Loan Schedule to reflect such substitution and
shall provide a copy of such amended Mortgage Loan Schedule to the Trustee and
the Rating Agencies.

          Section 2.05 ISSUANCE OF CERTIFICATES.

         (a) The Trustee acknowledges the assignment to it of the Mortgage Loans
and the other assets comprising the Trust Funds and, concurrently therewith, the
Certificate Registrar has signed, and countersigned and delivered to the
Depositor, in exchange therefor, the Certificates in such authorized
denominations representing such Fractional Undivided Interests as the Depositor
has requested. The Trustee agrees that it will hold the Mortgage Loans and such
other assets as may from time to time be delivered to it segregated on the books
of the Trustee in trust for the benefit of the related Certificateholders.

         (b) The Depositor, concurrently with the execution and delivery hereof,
does hereby transfer, assign, set over and otherwise convey in trust to the
Trustee without recourse all the right, title and interest of the Depositor in
and to the REMIC I Regular Interests and the other assets of REMIC III for the
benefit of the holders of the REMIC III Interests. The Trustee acknowledges
receipt of the REMIC I Regular Interests (which are uncertificated) and the
other assets of REMIC III and declares that it holds and will hold the same in
trust for the exclusive use and benefit of the holders of the REMIC III
Interests.

         (c) The Depositor, concurrently with the execution and delivery hereof,
does hereby transfer, assign, set over and otherwise convey in trust to the
Trustee without recourse all the right, title and interest of the Depositor in
and to the REMIC II Regular Interests, the REMIC III Regular Interests and the
other assets of REMIC IV for the benefit of the Holders of the REMIC IV
Certificates. The Trustee acknowledges receipt of the REMIC II Regular Interests
(which are uncertificated), the REMIC III Regular Interests (which are
uncertificated) and the other assets of REMIC IV and declares that it holds and
will hold the same in trust for the exclusive use and benefit of the Holders of
the REMIC IV Certificates.

         Section 2.06 REPRESENTATIONS AND WARRANTIES CONCERNING THE DEPOSITOR.

         The Depositor hereby represents and warrants to the Trustee, the Master
Servicer and the Securities Administrator as follows:

         (a) the Depositor (i) is a corporation duly organized, validly existing
and in good standing under the laws of the State of Delaware and (ii) is

enter into this Agreement and to consummate the transactions contemplated
hereby;

         (b) the Depositor has full corporate power to own its property, to
carry on its business as presently conducted and to enter into and perform its

articles of incorporation or by-laws of the Depositor, except those conflicts,
breaches or defaults which would not reasonably be expected to have a material
adverse effect on the Depositor's ability to enter into this Agreement and to
consummate the transactions contemplated hereby;

         (d) the execution, delivery and performance by the Depositor of this
Agreement and the consummation of the transactions contemplated hereby do not
require the consent or approval of, the giving of notice to, the registration

other governmental authority or agency, except those consents, approvals,
notices, registrations or other actions as have already been obtained, given or
made;

         (e) this Agreement has been duly executed and delivered by the
Depositor and, assuming due authorization, execution and delivery by the other

to any other matter which in the judgment of the Depositor will be determined
adversely to the Depositor and will if determined adversely to the Depositor
materially and adversely affect the Depositor's ability to enter into this
Agreement or perform its obligations under this Agreement; and the Depositor is
not in default with respect to any order of any court, administrative agency,

                                   ARTICLE III
        Administration of the Trust Fund and Servicing of Mortgage Loans

         Section 3.01 MASTER SERVICER AND SECURITIES ADMINISTRATOR.

          The Master Servicer shall supervise, monitor and oversee the obligation
of the Servicers to service and administer their respective Mortgage Loans in
accordance with the terms of the applicable Servicing Agreements and shall have
full power and authority to do any and all things which it may deem necessary or
desirable in connection with such master servicing and administration. In
performing its obligations hereunder, the Master Servicer shall act in a manner
consistent with Accepted Master Servicing Practices. Furthermore, the Master
Servicer shall oversee and consult with each Servicer as necessary from
time-to-time to carry out the Master Servicer's obligations hereunder, shall
receive, review and evaluate all reports, information and other data provided to
the Master Servicer by each Servicer and shall cause each Servicer to perform
and observe the covenants, obligations and conditions to be performed or
observed by such Servicer under its applicable Servicing Agreement. The Master
Servicer shall independently and separately monitor each Servicer's servicing
activities with respect to each related Mortgage Loan, reconcile the results of
such monitoring with such information provided in the previous sentence on a
monthly basis and coordinate corrective adjustments to the Servicers' and Master
Servicer's records, and based on such reconciled and corrected information, the
Master Servicer shall provide such information to the Securities Administrator
as shall be necessary in order for it to prepare the statements specified in
Section 6.05(a), and prepare any other information and statements required to be
forwarded by the Master Servicer hereunder. The Master Servicer shall reconcile
the results of its Mortgage Loan monitoring with the actual remittances of the
Servicers pursuant to the applicable Servicing Agreements.

         The Trustee shall furnish the Servicers and the Master Servicer with
any powers of attorney and other documents in form as provided to it necessary
or appropriate to enable the Servicers and the Master Servicer to service and
administer the related Mortgage Loans and REO Property. The Trustee shall be
indemnified by the Master Servicer for any costs, liabilities or expenses
incurred by it in connection with such powers of attorney.

         The Trustee or the Custodian shall provide access to the records and
documentation in possession of the Trustee regarding the related Mortgage Loans
and REO Property and the servicing thereof to the related Certificateholders,
the FDIC, and the supervisory agents and examiners of the FDIC, such access
being afforded only upon reasonable prior written request and during normal
business hours at the office of the Trustee; provided, however, that, unless
otherwise required by law, the Trustee shall not be required to provide access
to such records and documentation if the provision thereof would violate the
legal right to privacy of any Mortgagor. The Trustee shall allow representatives
of the above entities to photocopy any of the records and documentation and
shall provide equipment for that purpose at a charge that covers the Trustee's
actual costs.

         The Trustee shall execute and deliver to the related Servicer and the
Master Servicer any court pleadings, requests for trustee's sale or other
documents necessary or desirable to (i) the foreclosure or trustee's sale with
respect to a Mortgaged Property; (ii) any legal action brought to obtain
judgment against any Mortgagor on the Mortgage Note or Security Instrument;
(iii) obtain a deficiency judgment against the Mortgagor; or (iv) enforce any
other rights or remedies provided by the Mortgage Note or Security Instrument or
otherwise available at law or equity.

         Section 3.02 REMIC-RELATED COVENANTS.

         For as long as each REMIC shall exist, the Trustee and the Securities
Administrator shall act in accordance herewith to assure continuing treatment of
such REMIC as a REMIC, and the Trustee and the Securities Administrator shall
comply with any directions of the Depositor, the related Servicer or the Master
Servicer to assure such continuing treatment. In particular, the Trustee shall
not (a) sell or permit the sale of all or any portion of the Mortgage Loans or
of any investment of deposits in an Account unless such sale is as a result of a
repurchase of the Mortgage Loans pursuant to this Agreement or the Trustee has
received a REMIC Opinion addressed to the Trustee prepared at the expense of the
Trust Fund; and (b) other than with respect to a substitution pursuant to the
Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as
applicable, accept any contribution to any REMIC after the Startup Day without
receipt of a REMIC Opinion addressed to the Trustee.

         Section 3.03 MONITORING OF SERVICERS.

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

         (b) The Master Servicer, for the benefit of the Trustee and the
Certificateholders, shall enforce the obligations of each Servicer under the
related Servicing Agreement, and shall, in the event that a Servicer other than
Wells Fargo fails to perform its obligations in accordance with the related
Servicing Agreement, subject to the preceding paragraph, terminate the rights
and obligations of such Servicer thereunder and act as servicer of the related
Mortgage Loans or to cause the Trustee to enter into a new Servicing Agreement
with a successor Servicer selected by the Master Servicer; provided, however, it
is understood and acknowledged by the parties hereto that there will be a period
of transition (not to exceed 90 days) before the actual servicing functions can
be fully transferred to such successor Servicer. In the event that Wells Fargo
fails to perform its obligations in accordance with the Wells Fargo Servicing
Agreement, subject to the preceding paragraph, the Master Servicer shall notify
the Trustee in writing of such failure. Pursuant to its receipt of such
notification from the Master Servicer, the Trustee shall terminate the rights
and obligations of Wells Fargo under the Wells Fargo Servicing Agreement and
enter in to a new Servicing Agreement with a successor Servicer selected by the
Trustee; provided, however, it is understood and acknowledged by the parties
hereto that there will be a period of transition (not to exceed 90 days) before
the actual servicing functions can be fully transferred to such successor
Servicer. In either event, such enforcement, including, without limitation, the
legal prosecution of claims, termination of Servicing Agreements and the pursuit
of other appropriate remedies, shall be in such form and carried out to such an
extent and at such time as the Master Servicer (or in the case Wells Fargo is
terminated as the Servicer, the Trustee) in its good faith business judgment,
would require were it the owner of the related Mortgage Loans. The Master
Servicer shall pay the costs of such enforcement at its own expense, provided
that the Master Servicer shall not be required to prosecute or defend any legal
action except to the extent that the Master Servicer shall have received
reasonable indemnity for its costs and expenses in pursuing such action. In the
event that Wells Fargo is terminated as the Servicer, the Trustee shall pay the
costs of such enforcement at its own expense, subject to its right to be
reimbursed for such costs from the Master Servicer Collection Account pursuant
to Section 3.03(c); provided that the Trustee shall not be required to prosecute
or defend any legal action except to the extent that the Trustee shall have
received reasonable indemnity for its costs and expenses in pursuing such
action. Nothing herein shall impose any obligation on the part of the Trustee to
assume or succeed to the duties or obligations of Wells Fargo or the Master
Servicer.

         (c) In the event that Wells Fargo is terminated as Servicer, to the
extent that the costs and expenses of the Trustee related to any termination of
Wells Fargo, or the enforcement or prosecution of related claims, rights or
remedies, or the appointment of a successor Servicer (including, without
limitation, (i) all legal costs and expenses and all due diligence costs and
expenses associated with an evaluation of the potential termination of the Wells
Fargo as a result of an event of default by Wells Fargo and (ii) all costs and
expenses associated with the complete transfer of servicing, including all
servicing files and all servicing data and the completion, correction or
manipulation of such servicing data as may be required by the successor Servicer
to correct any errors or insufficiencies in the servicing data or otherwise to
enable the successor Servicer to service the Mortgage Loans in accordance with
the related Servicing Agreement) are not fully and timely reimbursed by Wells
Fargo after such termination, the Trustee shall be entitled to reimbursement of
such costs and expenses from the Master Servicer Collection Account (which the
Master Servicer hereby agrees to pay to the Trustee from the Master Servicer
Collection Account upon demand) or, to the extent not paid from such account,
the Trustee shall be entitled to reimburse itself for such costs and expenses
from the Distribution Account. In all other cases, to the extent that the costs
and expenses of the Master Servicer related to any termination of a Servicer
(other than Wells Fargo), appointment of a successor Servicer or the transfer
and assumption of servicing by the Master Servicer with respect to any Servicing
Agreement (including, without limitation, (i) all legal costs and expenses and
all due diligence costs and expenses associated with an evaluation of the
potential termination of the Servicer as a result of an event of default by such
Servicer and (ii) all costs and expenses associated with the complete transfer
of servicing, including all servicing files and all servicing data and the
completion, correction or manipulation of such servicing data as may be required
by the successor servicer to correct any errors or insufficiencies in the
servicing data or otherwise to enable the successor servicer to service the
Mortgage Loans in accordance with the related Servicing Agreement) are not fully
and timely reimbursed by the terminated Servicer, the Master Servicer shall be
entitled to reimbursement of such costs and expenses from the Master Servicer
Collection Account.

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

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

         Section 3.04 FIDELITY BOND.

         The Master Servicer, at its expense, shall maintain in effect a blanket
fidelity bond and an errors and omissions insurance policy, affording coverage
with respect to all directors, officers, employees and other Persons acting on
such Master Servicer's behalf, and covering errors and omissions in the
performance of the Master Servicer's obligations hereunder. The errors and
omissions insurance policy and the fidelity bond shall be in such form and
amount generally acceptable for entities serving as master servicers or
trustees.

         Section 3.05 POWER TO ACT; PROCEDURES.

         The Master Servicer shall master service the Mortgage Loans and shall
have full power and authority, subject to the REMIC Provisions and the
provisions of Article X hereof, to do any and all things that it may deem
necessary or desirable in connection with the master servicing and
administration of the Mortgage Loans, including but not limited to the power and
authority (i) to execute and deliver, on behalf of the Holders of the
Certificates and the Trustee, customary consents or waivers and other
instruments and documents, (ii) to consent to transfers of any Mortgaged
Property and assumptions of the Mortgage Notes and related Mortgages, (iii) to
collect any Insurance Proceeds, Liquidation Proceeds and Subsequent Recoveries,
and (iv) to effectuate foreclosure or other conversion of the ownership of the
Mortgaged Property securing any Mortgage Loan, in each case, in accordance with
the provisions of this Agreement and the related Servicing Agreement, as
applicable; provided, however, that the Master Servicer shall not (and,
consistent with its responsibilities under Section 3.03, shall not permit any
Servicer to) knowingly or intentionally take any action, or fail to take (or
fail to cause to be taken) any action reasonably within its control and the
scope of duties more specifically set forth herein, that, under the REMIC
Provisions, if taken or not taken, as the case may be, would cause any related
REMIC to fail to qualify as a REMIC or result in the imposition of a tax upon
the Trust Funds (including but not limited to the tax on prohibited transactions
as defined in Section 860F(a)(2) of the Code and the tax on contributions to a
REMIC set forth in Section 860G(d) of the Code) unless the Master Servicer has
received an Opinion of Counsel (but not at the expense of the Master Servicer)
to the effect that the contemplated action would not cause any REMIC to fail to
qualify as a REMIC or result in the imposition of a tax upon any REMIC. The
Trustee shall furnish the Master Servicer, upon written request from a Servicing
Officer, with any powers of attorney empowering the Master Servicer or any
Servicer to execute and deliver instruments of satisfaction or cancellation, or
of partial or full release or discharge, and to foreclose upon or otherwise
liquidate Mortgaged Property, and to appeal, prosecute or defend in any court
action relating to the Mortgage Loans or the Mortgaged Property, in accordance
with the related Servicing Agreement and this Agreement, and the Trustee shall
execute and deliver such other documents, as the Master Servicer may request, to
enable the Master Servicer to master service and administer the Mortgage Loans
and carry out its duties hereunder, in each case in accordance with Accepted
Master Servicing Practices (and the Trustee shall have no liability for misuse
of any such powers of attorney by the Master Servicer or any Servicer). If the
Master Servicer or the Trustee has been advised that it is likely that the laws
of the state in which action is to be taken prohibit such action if taken in the
name of the Trustee or that the Trustee would be adversely affected under the
"doing business" or tax laws of such state if such action is taken in its name,
the Master Servicer shall join with the Trustee in the appointment of a
co-trustee pursuant to Section 9.11 hereof. In the performance of its duties
hereunder, the Master Servicer shall be an independent contractor and shall not,
except in those instances where it is taking action in the name of the Trustee,
be deemed to be the agent of the Trustee.

         Section 3.06 DUE-ON-SALE CLAUSES; ASSUMPTION AGREEMENTS.

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

         Section 3.07 RELEASE OF MORTGAGE FILES.

         (a) Upon becoming aware of the payment in full of any Mortgage Loan, or
the receipt by any Servicer of a notification that payment in full has been
escrowed in a manner customary for such purposes for payment to related
Certificateholders on the next Distribution Date, the Servicer will, if required
under the applicable Servicing Agreement (or if the applicable Servicer does
not, the Master Servicer may), promptly furnish to the Custodian, on behalf of
the Trustee, two copies of a certification substantially in the form of Exhibit
D hereto signed by a Servicing Officer or in a mutually agreeable electronic
format which will, in lieu of a signature on its face, originate from a
Servicing Officer (which certification shall include a statement to the effect
that all amounts received in connection with such payment that are required to
be deposited in the Protected Account maintained by the applicable Servicer
pursuant to Section 4.01 or by the applicable Servicer pursuant to the
applicable Servicing Agreement have been or will be so deposited) and shall
request that the Custodian, on behalf of the Trustee, deliver to the Servicer
the related Mortgage File. Upon receipt of such certification and request, the
Custodian, on behalf of the Trustee, shall promptly release the related Mortgage
File to the Servicer and the Trustee and Custodian shall have no further
responsibility with regard to such Mortgage File. Upon any such payment in full,
each Servicer is authorized, to give, as agent for the Trustee, as the mortgagee
under the Mortgage that secured the Mortgage Loan, an instrument of satisfaction
(or assignment of mortgage without recourse) regarding the Mortgaged Property
subject to the Mortgage, which instrument of satisfaction or assignment, as the
case may be, shall be delivered to the Person or Persons entitled thereto
against receipt therefor of such payment, it being understood and agreed that no
expenses incurred in connection with such instrument of satisfaction or
assignment, as the case may be, shall be chargeable to the Protected Account.

         (b) From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan and in accordance with the applicable Servicing
Agreement, the Trustee shall execute such documents as shall be prepared and
furnished to the Trustee by a Servicer or the Master Servicer (in form
reasonably acceptable to the Trustee) and as are necessary to the prosecution of
any such proceedings. The Custodian, on behalf of the Trustee, shall, upon the
request of a Servicer or the Master Servicer, and delivery to the Custodian, on
behalf of the Trustee, of two copies of a request for release signed by a
Servicing Officer substantially in the form of Exhibit D (or in a mutually
agreeable electronic format which will, in lieu of a signature on its face,
originate from a Servicing Officer), release the related Mortgage File held in
its possession or control to the Servicer or the Master Servicer. Such trust
receipt shall obligate the Servicer or the Master Servicer to return the
Mortgage File to the Custodian on behalf of the Trustee, when the need therefor
by the Servicer or the Master Servicer no longer exists unless the Mortgage Loan
shall be liquidated, in which case, upon receipt of a certificate of a Servicing
Officer similar to that hereinabove specified, the Mortgage File shall be
released by the Custodian, on behalf of the Trustee, to the Servicer or the
Master Servicer.

         Section 3.08 DOCUMENTS, RECORDS AND FUNDS IN POSSESSION OF MASTER
SERVICER TO BE HELD FOR TRUSTEE.

         (a) The Master Servicer shall transmit and each Servicer (to the extent
required by the related Servicing Agreement) shall transmit to the Trustee or
Custodian such documents and instruments coming into the possession of the
Master Servicer or such Servicer from time to time as are required by the terms
hereof, or in the case of the Servicers, the applicable Servicing Agreement, to
be delivered to the Trustee or Custodian. Any funds received by the Master
Servicer or by a Servicer in respect of any Mortgage Loan or which otherwise are
collected by the Master Servicer or by a Servicer as Liquidation Proceeds,
Insurance Proceeds or Subsequent Recoveries in respect of any Mortgage Loan
shall be held for the benefit of the Trustee and the related Certificateholders
subject to the Master Servicer's right to retain or withdraw from the Master
Servicer Collection Account the Master Servicing Compensation and other amounts
provided in this Agreement, and to the right of each Servicer to retain its
Servicing Fee and other amounts as provided in the applicable Servicing
Agreement. The Master Servicer shall, and (to the extent provided in the
applicable Servicing Agreement) shall cause each Servicer to, provide access to
information and documentation regarding the Mortgage Loans to the Trustee, its
agents and accountants at any time upon reasonable request and during normal
business hours, to related Certificateholders that are savings and loan
associations, banks or insurance companies, the Office of Thrift Supervision,
the FDIC and the supervisory agents and examiners of such Office and Corporation
or examiners of any other federal or state banking or insurance regulatory
authority if so required by applicable regulations of the Office of Thrift
Supervision or other regulatory authority, such access to be afforded without
charge but only upon reasonable request in writing and during normal business
hours at the offices of the Master Servicer designated by it. In fulfilling such
a request the Master Servicer shall not be responsible for determining the
sufficiency of such information.

         (b) All Mortgage Files and funds collected or held by, or under the
control of, the Master Servicer, in respect of any Mortgage Loans, whether from
the collection of principal and interest payments or from Liquidation Proceeds,
Insurance Proceeds or Subsequent Recoveries, shall be held by the Master
Servicer for and on behalf of the Trustee and the related Certificateholders and
shall be and remain the sole and exclusive property of the Trustee; provided,
however, that the Master Servicer and each Servicer shall be entitled to setoff
against, and deduct from, any such funds any amounts that are properly due and
payable to the Master Servicer or such Servicer under this Agreement or the
applicable Servicing Agreement.

         Section 3.09 STANDARD HAZARD INSURANCE AND FLOOD INSURANCE POLICIES.

         (a) For each Mortgage Loan, the Master Servicer shall enforce any
obligation of the Servicers under the related Servicing Agreements to maintain
or cause to be maintained standard fire and casualty insurance and, where
applicable, flood insurance, all in accordance with the provisions of the
related Servicing Agreements. It is understood and agreed that such insurance
shall be with insurers meeting the eligibility requirements set forth in the
applicable Servicing Agreement and that no earthquake or other additional
insurance is to be required of any Mortgagor or to be maintained on property
acquired in respect of a defaulted loan, other than pursuant to such applicable
laws and regulations as shall at any time be in force and as shall require such
additional insurance.

         (b) Pursuant to Section 4.01 and 4.02, any amounts collected by the
Servicers or the Master Servicer, or by any Servicer, under any insurance
policies (other than amounts to be applied to the restoration or repair of the
property subject to the related Mortgage or released to the Mortgagor in
accordance with the applicable Servicing Agreement) shall be deposited into the
Master Servicer Collection Account, subject to withdrawal pursuant to Section
4.02 and 4.03. Any cost incurred by the Master Servicer or any Servicer in
maintaining any such insurance if the Mortgagor defaults in its obligation to do
so shall be added to the amount owing under the Mortgage Loan where the terms of
the Mortgage Loan so permit; provided, however, that the addition of any such
cost shall not be taken into account for purposes of calculating the
distributions to be made to Certificateholders and shall be recoverable by the
Master Servicer or such Servicer pursuant to Section 4.02 and 4.03.

         Section 3.10 PRESENTMENT OF CLAIMS AND COLLECTION OF PROCEEDS.

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

         Section 3.11 MAINTENANCE OF THE PRIMARY MORTGAGE INSURANCE POLICIES.

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

         (b) The Master Servicer agrees to present, or to cause each Servicer
(to the extent required under the related Servicing Agreement) to present, on
behalf of the Trustee and the Certificateholders, claims to the insurer under
any Primary Mortgage Insurance Policies and, in this regard, to take such
reasonable action as shall be necessary to permit recovery under any Primary
Mortgage Insurance Policies respecting defaulted Mortgage Loans. Pursuant to
Section 4.01 and 4.02, any amounts collected by the Master Servicer or any
Servicer under any Primary Mortgage Insurance Policies shall be deposited in the
Master Servicer Collection Account, subject to withdrawal pursuant to Sections
4.02 and 4.03.

         Section 3.12 TRUSTEE TO RETAIN POSSESSION OF CERTAIN INSURANCE POLICIES
AND DOCUMENTS.

         The Trustee (or the Custodian, as directed by the Trustee), shall
retain possession and custody of the originals (to the extent available) of any
Primary Mortgage Insurance Policies, or certificate of insurance if applicable,
and any certificates of renewal as to the foregoing as may be issued from time
to time as contemplated by this Agreement. Until all amounts distributable in
respect of the Certificates have been distributed in full and the Master
Servicer otherwise has fulfilled its obligations under this Agreement, the
Trustee (or its Custodian, if any, as directed by the Trustee) shall also retain
possession and custody of each Mortgage File in accordance with and subject to
the terms and conditions of this Agreement. The Master Servicer shall promptly
deliver or cause to be delivered to the Trustee (or the Custodian, as directed
by the Trustee), upon the execution or receipt thereof the originals of any
Primary Mortgage Insurance Policies, any certificates of renewal, and such other
documents or instruments that constitute portions of the Mortgage File that come
into the possession of the Master Servicer from time to time.

         Section 3.13 REALIZATION UPON DEFAULTED MORTGAGE LOANS.

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

         Section 3.14 COMPENSATION FOR THE MASTER SERVICER.

         The Master Servicer will be entitled to (i) the Master Servicing Fee;
provided, that the aggregate Master Servicing Fee with respect to any
Distribution Date shall be reduced by an amount equal to the Compensating
Interest payable by the Master Servicer for such Distribution Date pursuant to
Section 6.07 hereof, plus (ii) all income and gain realized from any investment
of funds in the Distribution Account and the Master Servicer Collection Account,
pursuant to Article IV, for the performance of its activities hereunder.
Servicing compensation in the form of assumption fees, if any, late payment
charges, as collected, if any, or otherwise (but not including any prepayment
premium or penalty) shall be retained by the applicable Servicer and shall not
be deposited in the Protected Account. The Master Servicer shall be required to
pay all expenses incurred by it in connection with its activities hereunder and
shall not be entitled to reimbursement therefor except as provided in this
Agreement.

         Section 3.15 REO PROPERTY.

         (a) In the event the Trust Fund acquires ownership of any REO Property
in respect of any related Mortgage Loan, the deed or certificate of sale shall
be issued to the Trustee, or to its nominee, on behalf of the related
Certificateholders. The Master Servicer shall, to the extent provided in the
applicable Servicing Agreement, cause the applicable Servicer to sell any REO
Property as expeditiously as possible and in accordance with the provisions of
this Agreement and the related Servicing Agreement, as applicable. Pursuant to
its efforts to sell such REO Property, the Master Servicer shall cause the
applicable Servicer to protect and conserve, such REO Property in the manner and
to the extent required by the applicable Servicing Agreement, in accordance with
the REMIC Provisions and in a manner that does not result in a tax on "net
income from foreclosure property" or cause such REO Property to fail to qualify
as "foreclosure property" within the meaning of Section 860G(a)(8) of the Code.

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

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

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

         Section 3.16 ANNUAL OFFICER'S CERTIFICATE AS TO COMPLIANCE.

         (a) The Master Servicer shall deliver to the Trustee and the Rating
Agencies on or before March 1 of each year, commencing on March 1, 2006, an
Officer's Certificate, certifying that with respect to the period ending
December 31 of the prior year: (i) such Servicing Officer has reviewed the
activities of such Master Servicer during the preceding calendar year or portion
thereof and its performance under this Agreement, (ii) to the best of such
Servicing Officer's knowledge, based on such review, such Master Servicer has
performed and fulfilled its duties, responsibilities and obligations under this
Agreement in all material respects throughout such year, or, if there has been a
default in the fulfillment of any such duties, responsibilities or obligations,
specifying each such default known to such Servicing Officer and the nature and
status thereof, (iii) nothing has come to the attention of such Servicing
Officer to lead such Servicing Officer to believe that any Servicer has failed
to perform any of its duties, responsibilities and obligations under its
Servicing Agreement in all material respects throughout such year, or, if there
has been a material default in the performance or fulfillment of any such
duties, responsibilities or obligations, specifying each such default known to
such Servicing Officer and the nature and status thereof.

         (b) Copies of such statements shall be provided to any
Certificateholder upon request, by the Master Servicer or by the Trustee at the
Master Servicer's expense if the Master Servicer failed to provide such copies
(unless (i) the Master Servicer shall have failed to provide the Trustee with
such statement or (ii) the Trustee shall be unaware of the Master Servicer's
failure to provide such statement).

         Section 3.17 ANNUAL INDEPENDENT ACCOUNTANT'S SERVICING REPORT.

         If the Master Servicer has, during the course of any calendar year,
directly serviced any of the Mortgage Loans, then the Master Servicer at its
expense shall cause a nationally recognized firm of independent certified public
accountants to furnish a statement to the Trustee, the Rating Agencies and the
Depositor on or before March 1 of each year to the effect that, with respect to
the most recently ended calendar year, such firm has examined certain records
and documents relating to the Master Servicer's performance of its servicing
obligations under this Agreement and pooling and servicing and trust agreements
in material respects similar to this Agreement and to each other and that, on
the basis of such examination conducted substantially in compliance with the
audit program for mortgages serviced for Freddie Mac or the Uniform Single
Attestation Program for Mortgage Bankers, such firm is of the opinion that the
Master Servicer's activities have been conducted in compliance with this
Agreement, or that such examination has disclosed no material items of
noncompliance except for (i) such exceptions as such firm believes to be
immaterial, (ii) such other exceptions as are set forth in such statement and
(iii) such exceptions that the Uniform Single Attestation Program for Mortgage
Bankers or the Audit Program for Mortgages Serviced by Freddie Mac requires it
to report. Copies of such statements shall be provided to any Certificateholder
upon request by the Master Servicer, or by the Trustee at the expense of the
Master Servicer if the Master Servicer shall fail to provide such copies but
only if the Master Servicer has provided the Trustee with such statement. If
such report discloses exceptions that are material, the Master Servicer shall
advise the Trustee whether such exceptions have been or are susceptible of cure,
and will take prompt action to do so.

         Section 3.18 REPORTS FILED WITH SECURITIES AND EXCHANGE COMMISSION.

         Within 15 days after each Distribution Date, the Securities
Administrator shall, in accordance with industry standards, file with the
Commission via the Electronic Data Gathering and Retrieval System ("EDGAR"), a
Form 8-K (or other comparable form containing the comparable information or
other information mutually agreed upon) with a copy of Certificate Distribution
Report for such Distribution Date as an exhibit thereto. Prior to January 30 in
any year, the Securities Administrator shall, in accordance with industry
standards and only if instructed by the Depositor, file a Form 15 Suspension
Notice with respect to the Trust Fund, if applicable. Prior to (i) March 15,
2006 and (ii) unless and until a Form 15 Suspension Notice shall have been
filed, prior to March 15 of each year thereafter, the Master Servicer shall
provide the Securities Administrator with a Master Servicer Certification,
together with a copy of the annual independent accountant's servicing report of
each Servicer and annual statement of compliance of each Servicer, in each case,
required to be delivered pursuant to the related Servicing Agreement, and, if
applicable, the annual independent accountant's servicing report and annual
statement of compliance to be delivered by the Master Servicer pursuant to
Sections 3.16 and 3.17. Prior to (i) March 31, 2006, or such earlier filing date
as may be required by the Commission, and (ii) unless and until a Form 15
Suspension Notice shall have been filed, March 31 of each year thereafter, or
such earlier filing date as may be required by the Commission, the Securities
Administrator shall file a Form 10-K, in substance conforming to industry
standards, with respect to the Trust Fund. Such Form 10-K shall include the
Master Servicer Certification and other documentation provided by the Master
Servicer pursuant to the second preceding sentence. The Depositor hereby grants
to the Securities Administrator a limited power of attorney to execute and file
each such document on behalf of the Depositor. Such power of attorney shall
continue until either the earlier of (i) receipt by the Securities Administrator
from the Depositor of written termination of such power of attorney and (ii) the
termination of the Trust Fund. The Depositor agrees to promptly furnish to the
Securities Administrator, from time to time upon request, such further
information, reports and financial statements within its control related to this
Agreement and the Mortgage Loans as the Securities Administrator reasonably
deems appropriate to prepare and file all necessary reports with the Commission.
The Securities Administrator shall have no responsibility to file any items
other than those specified in this Section 3.18; provided, however, the
Securities Administrator will cooperate with the Depositor in connection with
any additional filings with respect to the Trust Fund as the Depositor deems
necessary under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"). Fees and expenses incurred by the Securities Administrator in connection
with this Section 3.18 shall not be reimbursable from the Trust Fund.

         Section 3.19 [Reserved].

         Section 3.20 UCC.

         The Depositor shall inform the Trustee in writing of any Uniform
Commercial Code financing statements that were filed on the Closing Date in
connection with the Trust with stamped recorded copies of such financing
statements to be delivered to the Trustee promptly upon receipt by the
Depositor. If directed by the Depositor in writing, the Trustee will file any
continuation statements solely at the expense of the Depositor. The Depositor
shall file any financing statements or amendments thereto required by any change
in the Uniform Commercial Code.

         Section 3.21 OPTIONAL PURCHASE OF DEFAULTED MORTGAGE LOANS.

         (a) With respect to any Mortgage Loan which as of the first day of a
Fiscal Quarter is delinquent in payment by 90 days or more or is an REO
Property, the Company shall have the right to purchase such Mortgage Loan from
the Trust at a price equal to the Repurchase Price; provided however (i) that
such Mortgage Loan is still 90 days or more delinquent or is an REO Property as
of the date of such purchase and (ii) this purchase option, if not theretofore
exercised, shall terminate on the date prior to the last day of the related
Fiscal Quarter. This purchase option, if not exercised, shall not be thereafter
reinstated unless the delinquency is cured and the Mortgage Loan thereafter
again becomes 90 days or more delinquent or becomes an REO Property, in which
case the option shall again become exercisable as of the first day of the
related Fiscal Quarter.

         (b) If at any time the Company remits to the Master Servicer a payment
for deposit in the Master Servicer Collection Account covering the amount of the
Repurchase Price for such a Mortgage Loan, and the Company provides to the
Trustee a certification signed by a Servicing Officer stating that the amount of
such payment has been deposited in the Master Servicer Collection Account, then
the Trustee shall execute the assignment of such Mortgage Loan to the Company at
the request of the Company without recourse, representation or warranty and the
Company shall succeed to all of the Trustee's right, title and interest in and
to such Mortgage Loan, and all security and documents relative thereto. Such
assignment shall be an assignment outright and not for security. The Company
will thereupon own such Mortgage, and all such security and documents, free of
any further obligation to the Trustee or the Certificateholders with respect
thereto.

         Section 4.01 PROTECTED ACCOUNT.

         (a) The Master Servicer shall enforce the obligation of each Servicer

receipt, all collections of principal and interest on any Mortgage Loan and any
REO Property received by a Servicer, including Principal Prepayments, Insurance

funds. Such Permitted Investments shall mature, or shall be subject to
redemption or withdrawal, no later than the date on which such funds are
required to be withdrawn for deposit in the Master Servicer Collection Account,
and shall be held until required for such deposit. The income earned from
Permitted Investments made pursuant to this Section 4.01 shall be paid to the

of moneys required to be distributed to the Holders of the Certificates

related portion thereof advanced by such Servicer pursuant to its Servicing
Agreement which were due on or before the related Due Date, net of the amount
thereof comprising its Servicing Fee or any fees with respect to any lender-paid
primary mortgage insurance policy;

                  (ii) Full Principal Prepayments and any Liquidation Proceeds
or Subsequent Recoveries received by such Servicer with respect to the Mortgage

provided in Section 4.01(c), 4.02 and 4.03; to reimburse the Master Servicer or
a Servicer for Monthly Advances which have been recovered by subsequent
collections from the related Mortgagor; to remove amounts deposited in error; to
remove fees, charges or other such amounts deposited on a temporary basis; or to
clear and terminate the account at the termination of the Trust Fund in
accordance with Section 10.01. As provided in Sections 4.01(a) and 4.02(b)
certain amounts otherwise due to the Servicers may be retained by them and need
not be deposited in the Master Servicer Collection Account.

          Section 4.02 MASTER SERVICER COLLECTION ACCOUNT.

         (a) The Master Servicer shall establish and maintain in the name of the
Trustee, for the benefit of the Holders of the Certificates, the Master Servicer
Collection Account as a segregated trust account or accounts. The Master
Servicer Collection Account shall be an Eligible Account. The Master Servicer
will deposit in the Master Servicer Collection Account as identified by the
Master Servicer and as received by the Master Servicer, the following amounts:

                  (ii) Any Monthly Advance and any Compensating Interest
Payments;

                  (iii) Any Insurance Proceeds or Net Liquidation Proceeds or

                  (iv) The Repurchase Price with respect to any Mortgage Loans
purchased by the Seller pursuant to the Mortgage Loan Purchase Agreement or
Sections 2.02 or 2.03 hereof, any amounts which are to be treated pursuant to
Section 2.04 of this Agreement as the payment of a Repurchase Price in
connection with the tender of a Substitute Mortgage Loan by the Seller, the
Repurchase Price with respect to any Mortgage Loans purchased by the Company
pursuant to Section 3.21, and all proceeds of any Mortgage Loans or property
acquired with respect thereto repurchased by the Depositor or its designee

         (b) All amounts deposited to the Master Servicer Collection Account
shall be held by the Master Servicer in the name of the Trustee in trust for the
benefit of the Certificateholders in accordance with the terms and provisions of

fees and charges and (ii) the items enumerated in Subsections 4.05(a)(i), (ii),
(iii), (iv), (vi), (vii), (viii), (ix), (x), (xi) and (xii), need not be
credited by the Master Servicer or the related Servicer to the Distribution
Account or the Master Servicer Collection Account, as applicable. In the event
that the Master Servicer shall deposit or cause to be deposited to the
Distribution Account any amount not required to be credited thereto, the
Trustee, upon receipt of a written request therefor signed by a Servicing
Officer of the Master Servicer, shall promptly transfer such amount to the
Master Servicer, any provision herein to the contrary notwithstanding.

         (c) The amount at any time credited to the Master Servicer Collection
Account may be invested, in the name of the Trustee, or its nominee, for the
benefit of the Holders of the Certificates, in Permitted Investments as directed
by Master Servicer. All Permitted Investments shall mature or be subject to
redemption or withdrawal on or before, and shall be held until, the next
succeeding Distribution Account Deposit Date. Any and all investment earnings on
amounts on deposit in the Master Servicer Account from time to time shall be for
the account of the Master Servicer. The Master Servicer from time to time shall
be permitted to withdraw or receive distribution of any and all investment
earnings from the Master Servicer Collection Account. The risk of loss of moneys
required to be distributed to the Holders of the Certificates resulting from
such investments shall be borne by and be the risk of the Master Servicer. The
Master Servicer shall deposit the amount of any such loss in the Master Servicer
Collection Account within two Business Days of receipt of notification of such
loss but not later than the second Business Day prior to the Distribution Date
on which the moneys so invested are required to be distributed to the
Certificateholders.

         Section 4.03 PERMITTED WITHDRAWALS AND TRANSFERS FROM THE MASTER
SERVICER COLLECTION ACCOUNT.

         (a) The Master Servicer will, from time to time on demand of a Servicer
or the Securities Administrator, make or cause to be made such withdrawals or
transfers from the Master Servicer Collection Account as the Master Servicer has
designated for such transfer or withdrawal pursuant to this Agreement and the
related Servicing Agreement. The Master Servicer may clear and terminate the
Master Servicer Collection Account pursuant to Section 10.01 and remove amounts
from time to time deposited in error.

         (b) On an ongoing basis, the Master Servicer shall withdraw from the
Master Servicer Collection Account (i) any expenses, costs and liabilities
recoverable by the Trustee, the Master Servicer or the Securities Administrator
or the Custodian pursuant to Sections 3.03, 7.03 and 9.05 and (ii) any amounts
payable to the Master Servicer as set forth in Section 3.14; provided however,

         Section 4.04 DISTRIBUTION ACCOUNT.

         (a) The Paying Agent shall establish and maintain in the name of the
Paying Agent, for the benefit of the related Certificateholders, the

         (b) All amounts deposited to the Distribution Account shall be held by
the Paying Agent in the name of the Paying Agent in trust for the benefit of the
related Certificateholders in accordance with the terms and provisions of this
Agreement.

         (c) The Distribution Account shall constitute a trust account of the
Trust Fund segregated on the books of the Paying Agent and held by the Paying
Agent in trust in its Corporate Trust Office, and the Distribution Account and
the funds deposited therein shall not be subject to, and shall be protected
from, all claims, liens, and encumbrances of any creditors or depositors of the
Paying Agent or the Master Servicer (whether made directly, or indirectly
through a liquidator or receiver of the Paying Agent or the Master Servicer).
The Distribution Account shall be an Eligible Account. The amount at any time
credited to the Distribution Account shall be (i) held in cash and fully insured
by the FDIC to the maximum coverage provided thereby or (ii) invested in the
name of the Paying Agent, in such Permitted Investments as may be selected by
the Master Servicer or deposited in demand deposits with such depository

deposits of such depository institutions would be a Permitted Investment. All
Permitted Investments shall mature or be subject to redemption or withdrawal on

Certificateholders shall be entitled to the priorities afforded to such a trust
account (in addition to a claim against the estate of the Paying Agent) as
provided by 12 U.S.C. ss. 92a(e), and applicable regulations pursuant thereto,
if applicable, or any applicable comparable state statute applicable to state
chartered banking corporations.

         Section 4.05 PERMITTED WITHDRAWALS AND TRANSFERS FROM THE DISTRIBUTION

(iv) or with respect to any such amounts which would have been covered by such
subclauses had the amounts not been retained by the Master Servicer without
being deposited in the Distribution Account under Section 4.02(b).

         (c) On each Distribution Date, the Paying Agent shall distribute the
Available Funds to the extent on deposit in the Distribution Account to the

         Section 5.01 CERTIFICATES.

         (a) The Depository, the Depositor and the Trustee have entered into a
Depository Agreement dated as of the Closing Date (the "Depository Agreement").
Except for the Residual Certificates, the Non-Offered Certificates (which are
also Physical Certificates) and the Individual Certificates and as provided in
Subsection 5.01(b), the Certificates shall at all times remain registered in the
name of the Depository or its nominee and at all times: (i) registration of such
Certificates may not be transferred by the Certificate Registrar except to a
successor to the Depository; (ii) ownership and transfers of registration of
such Certificates on the books of the Depository shall be governed by applicable
rules established by the Depository; (iii) the Depository may collect its usual
and customary fees, charges and expenses from its Depository Participants; (iv)
the Certificate Registrar shall deal with the Depository as representative of
such Certificate Owners of the respective Class of Certificates for purposes of
exercising the rights of the related Certificateholders under this Agreement,
and requests and directions for and votes of such representative shall not be
deemed to be inconsistent if they are made with respect to different Certificate
Owners; and (v) the Certificate Registrar may rely and shall be fully protected
in relying upon information furnished by the Depository with respect to its
Depository Participants.

         The Residual Certificates and the Non-Offered Certificates are
initially Physical Certificates. If at any time the Holders of all of the
Certificates of one or more such Classes request that the Certificate Registrar
cause such Class to become Global Certificates, the Certificate Registrar and
the Depositor will take such action as may be reasonably required to cause the
Depository to accept such Class or Classes for trading if it may legally be so
traded.

         All transfers by Certificate Owners of such respective Classes of
Book-Entry Certificates and any Global Certificates shall be made in accordance
with the procedures established by the Depository Participant or brokerage firm
representing such Certificate Owners. Each Depository Participant shall only
transfer Book-Entry Certificates of Certificate Owners it represents or of
brokerage firms for which it acts as agent in accordance with the Depository's
normal procedures.

         (b) If (i)(A) the Depositor advises the Certificate Registrar in
writing that the Depository is no longer willing or able to properly discharge
its responsibilities as Depository and (B) the Depositor is unable to locate a
qualified successor within 30 days or (ii) the Depositor at its option advises
the Certificate Registrar in writing that it elects to terminate the book-entry
system through the Depository, the Certificate Registrar shall request that the
Depository notify all Certificate Owners of the occurrence of any such event and
of the availability of definitive, fully registered Certificates to Certificate
Owners requesting the same. Upon surrender to the Certificate Registrar of the
Certificates by the Depository, accompanied by registration instructions from
the Depository for registration, the Certificate Registrar shall issue the
definitive Certificates. Neither the Depositor nor the Certificate Registrar
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.

     weighted average Net Mortgage Rate on the Group I Mortgage Loans with Net
     Mortgage Rates greater than 8.0000% per annum over (b) 8.0000% per annum.


         Interest shall be payable to the REMIC I Regular Interests at the
applicable Pass-Through Rates on the related Uncertificated Principal Balances
or Uncertificated Notional Amount. On the Distribution Date in January 2006,
REMIC I will be deemed to distribute to REMIC III $50 in respect of each of
REMIC I Regular Interest I-R-2 and REMIC I Regular Interest I-R-3 in reduction
of the Uncertificated Principal Balances thereof from the Class I-R Deposit.
Distributions of principal shall be deemed to be made to the REMIC I Regular
Interests, in each case from amounts received on the Group I Mortgage Loans in
the related Subgroup, first, to the related REMIC I Regular Interest ending with
the designation "Sub," so that the Uncertificated Principal Balance of each such
REMIC I Regular Interest is equal to 0.1% of the excess of (x) the aggregate
Scheduled Principal Balance of the Group I Mortgage Loans in the related
Subgroup other than the related PO Percentage of the Scheduled Principal Balance
of any Discount Mortgage Loan in Loan Group I over (y) the aggregate Current
Principal Amount of the Group I Senior Certificates related to such Subgroup
other than the Class I-PO Certificates (except that if any such excess is a
larger number than in the preceding distribution period, the least amount of
principal shall be distributed to such REMIC I Regular Interests such that the
REMIC I Subordinated Balance Ratio is maintained); and second, any remaining
principal from each Subgroup to the related REMIC I Regular Interest ending with
the designation "ZZZ" (provided that a portion of the remaining principal equal
to the Class I-PO Certificate Principal Distribution Amount attributable to the
Discount Mortgage Loans in Loan Group I will be distributed to REMIC I Regular
Interest PO). Realized Losses from each Subgroup shall be applied after all
distributions have been made on each Distribution Date, first, to the related
REMIC I Regular Interest ending with the designation "Sub," so that the
Uncertificated Principal Balance of each such REMIC I Regular Interest is equal
to 0.1% of the excess of (x) the aggregate Scheduled Principal Balance of the
Mortgage Loans in the related Subgroup other than the related PO Percentage of
the Scheduled Principal Balance of any Discount Mortgage Loan in Loan Group I
over (y) the aggregate Current Principal Amount of the Group I Senior
Certificates related to such Subgroup other than the Class I-PO Certificates
(except that if any such excess is a larger number than in the preceding
distribution period, the least amount of Realized Losses shall be applied to
such REMIC I Regular Interests such that the REMIC I Subordinated Balance Ratio
is maintained); and second, any remaining Realized Losses from each Subgroup to
the related REMIC I Regular Interests ending with the designation "ZZZ" (except
that if a Realized Loss is recognized with respect to a Discount Mortgage Loan
in Loan Group I, the applicable portion of such Realized Loss will be allocated
to REMIC I Regular Interest PO).

         The aggregate amount of any Net Interest Shortfalls related to the
Group I Mortgage Loans for any Distribution Date shall be allocated to accrued
interest payable to the REMIC I Regular Interests other than REMIC I Regular
Interest PO, PRO RATA, based on, and to the extent of, one month's interest at
the then applicable respective Pass-Through Rates on the respective
Uncertificated Principal Balances of each such REMIC I Regular Interest.

----------
(1)   As described in the definition of Notional Amount herein.

(2)   A variable pass-through rate equal to the excess, if any, of (a) the
     weighted average Net Mortgage Rate on the Group I Mortgage Loans with Net
     Mortgage Rates greater than 8.00% per annum over (b) 8.00% per annum;
     provided that, for federal income tax purposes the Class I-X Certificates
      will not have a Pass-Through Rate but will be entitled to receive 100% of
     the interest payable with respect to REMIC III Regular Interest I-X.

(3)   A variable pass-through rate equal to the weighted average of 7.00%, 7.50%
     and 8.00% per annum, weighted in proportion to the results of subtracting
     from the aggregate Scheduled Principal Balance of the Group I Mortgage
     Loans in Subgroup I-1, Subgroup I-2 and Subgroup I-3, respectively (other
     than the related PO Percentage of the principal balance of such Group I
     Mortgage Loans), the aggregate Current Principal Amount of the related
     Class or Classes of Group I Senior Certificates (other than the Class I-PO
     Certificates); provided that, for federal income tax purposes, the Class
     I-B Certificates will each bear interest at a rate equivalent to the
     foregoing, expressed as the weighted average of the Pass-Through Rates on
     REMIC III Regular Interests I-B-4, I-B-5 and I-B-6, weighted on the basis
     of the Uncertificated Principal Balances of each such REMIC III Regular
     Interest immediately preceding the related Distribution Date.

(4)   A variable pass-through rate equal to a per annum rate equal to the excess,
     if any, of (i) the weighted average of 7.00%, 7.50% and 8.00% per annum,
     weighted in proportion to the results of subtracting from the aggregate
     Scheduled Principal Balance of the Group I Mortgage Loans in Subgroup I-1,

     I-XB Certificates will bear interest at a rate equivalent to the foregoing,
     expressed as the weighted average of the Pass-Through Rates on REMIC III
     Regular Interests II-B-1, II-B-2 and II-B-3, weighted on the basis of the
     Uncertificated Principal Balances of each such REMIC III Regular Interest
     immediately preceding the related Distribution Date, minus 6.00%.

(5)   A variable pass-through rate equal to the excess, if any, of (a) the
     weighted average Net Mortgage Rate on the Group II Mortgage Loans with Net
     Mortgage Rates greater than 5.50% per annum over (b) 5.50% per annum;
     provided that, for federal income tax purposes the Class II-X Certificates
     will not have a Pass-Through Rate but will be entitled to receive 100% of
     the interest payable with respect to REMIC II Regular Interest II-X.


         (d) For purposes of Section 1.860G-1(a)(4)(iii) of the Treasury
regulations, the Distribution Date immediately following the maturity date for
the Group I Mortgage Loan with the latest maturity date in the Trust Fund has
been designated as the "latest possible maturity date" for the REMIC I Regular
Interests, REMIC III Regular Interests and the Group I Certificates, and the
Distribution Date immediately following the maturity date for the Group II
Mortgage Loan with the latest maturity date in the Trust Fund has been
designated as the "latest possible maturity date" for the REMIC II Regular
Interests and the Group II Certificates.

         (e) With respect to each Distribution Date, each Class of Certificates
(other than the Class R Certificates) shall accrue interest during the related
Interest Accrual Period. With respect to each Distribution Date and each such
Class of Certificates, interest shall be calculated on the basis of a 360-day
year comprised of twelve 30-day months, based upon the respective Pass-Through
Rate set forth, or determined as provided, above and the Current Principal
Amount (or Notional Amount in the case of the Interest Only Certificates) of
such Class applicable to such Distribution Date.

         (f) The Certificates shall be substantially in the forms set forth in
Exhibits A-1, A-2, A-3, A-4, A-5 or A-6, as applicable. On original issuance,
the Certificate Registrar shall sign, countersign and shall deliver them at the
direction of the Depositor. Pending the preparation of Definitive Certificates
of any Class, the Certificate Registrar may sign and countersign temporary
Certificates that are printed, lithographed or typewritten, in authorized
denominations for Certificates of such Class, substantially of the tenor of the
Definitive Certificates in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the
officers or authorized signatories executing such Certificates may determine, as
evidenced by their execution of such Certificates. If temporary Certificates are
issued, the Depositor will cause Definitive Certificates to be prepared without
unreasonable delay. After the preparation of Definitive Certificates, the
temporary Certificates shall be exchangeable for definitive Certificates upon
surrender of the temporary Certificates at the office of the Certificate
Registrar, without charge to the Holder. Upon surrender for cancellation of any
one or more temporary Certificates, the Certificate Registrar shall sign and
countersign and deliver in exchange therefor a like aggregate principal amount,
in authorized denominations for such Class, of Definitive Certificates of the
same Class. Until so exchanged, such temporary Certificates shall in all
respects be entitled to the same benefits as Definitive Certificates.

         (g) Each Class of Book-Entry Certificates will be registered as a
single Certificate of such Class held by a nominee of the Depository or the DTC
Custodian, and beneficial interests will be held by investors through the
book-entry facilities of the Depository in minimum denominations of in the case
of the Certificates (other than the Residual Certificates and the Class II-A-2
Certificates), $100,000, and for the Class II-A-2 Certificates, $1,000, and in
each case increments of $1.00 in excess thereof, except that one Certificate of
each such Class may be issued in a different amount so that the sum of the
denominations of all outstanding Certificates of such Class shall equal the
Current Principal Amount of such Class on the Closing Date. On the Closing Date,
the Certificate Registrar shall execute and countersign Physical Certificates
all in an aggregate principal amount that shall equal the Current Principal
Amount of such Class on the Closing Date. The Class I-R-1, Class I-R-2 and Class
I-R-3 Certificates shall each be issued in certificated fully-registered form,
in the denomination of $50. The Class II-R-1 Certificates shall each be issued
in certificated fully-registered form, in the denomination of $100. Each Class
of Global Certificates, if any, shall be issued in fully registered form in
minimum dollar denominations of $100,000 and integral multiples of $1.00 in
excess thereof, except that one Certificate of each Class may be in a different
denomination so that the sum of the denominations of all outstanding
Certificates of such Class shall equal the Current Principal Amount of such
Class on the Closing Date. On the Closing Date, the Certificate Registrar shall
execute and countersign (i) in the case of each Class of the Offered
Certificates, the Certificate in the entire Current Principal Amount of the
respective Class and (ii) in the case of each Class of the Non-Offered
Certificates, Individual Certificates all in an aggregate principal amount that
shall equal the Current Principal Amount of each such respective Class on the
Closing Date. The Certificates referred to in clauses (i) and (ii) and if at any
time there are to be Global Certificates, the Global Certificates shall be
delivered by the Depositor to the Depository or pursuant to the Depository's
instructions, shall be delivered by the Depositor on behalf of the Depository to
and deposited with the DTC Custodian. The Certificate Registrar shall sign the
Certificates by facsimile or manual signature and countersign them by manual
signature on behalf of the Certificate Registrar by one or more authorized
signatories, each of whom shall be Responsible Officers of the Certificate
Registrar or its agent. A Certificate bearing the manual and facsimile
signatures of individuals who were the authorized signatories of the Certificate
Registrar or its agent at the time of issuance shall bind the Certificate
Registrar, notwithstanding that such individuals or any of them have ceased to
hold such positions prior to the delivery of such Certificate.

         (h) No Certificate shall be entitled to any benefit under this
Agreement, or be valid for any purpose, unless there appears on such Certificate
the manually executed countersignature of the Certificate Registrar or its
agent, and such countersignature upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly executed
and delivered hereunder. All Certificates issued on the Closing Date shall be
dated the Closing Date. All Certificates issued thereafter shall be dated the
date of their countersignature.

         (i) The Closing Date is hereby designated as the "startup" day of each
REMIC within the meaning of Section 860G(a)(9) of the Code.

         (j) For federal income tax purposes, each REMIC shall have a tax year
that is a calendar year and shall report income on an accrual basis.

         (k) The Trustee on behalf of the Trust shall cause each REMIC to timely
elect to be treated as a REMIC under Section 860D of the Code. Any
inconsistencies or ambiguities in this Agreement or in the administration of any
Trust established hereby shall be resolved in a manner that preserves the
validity of such elections.

         (l) The following legend shall be placed on the Residual Certificates,
whether upon original issuance or upon issuance of any other Certificate of any
such Class in exchange therefor or upon transfer thereof:

                  THIS CERTIFICATE MAY NOT BE ACQUIRED DIRECTLY OR
         INDIRECTLY BY, OR ON BEHALF OF, AN EMPLOYEE BENEFIT PLAN OR

         CERTIFICATE REGISTRAR WITH AN OPINION OF COUNSEL ADDRESSED TO
         THE DEPOSITOR, TRUSTEE, CERTIFICATE REGISTRAR, MASTER
         SERVICER AND SECURITIES ADMINISTRATOR AND ON WHICH THEY MAY
         RELY THAT IS SATISFACTORY TO THE TRUSTEE THAT THE PURCHASE OF
         CERTIFICATES ON BEHALF OF SUCH PERSON WILL NOT RESULT IN OR
         CONSTITUTE A NONEXEMPT PROHIBITED TRANSACTION, IS PERMISSIBLE
         UNDER APPLICABLE LAW AND WILL NOT GIVE RISE TO ANY ADDITIONAL
         OBLIGATIONS ON THE PART OF THE DEPOSITOR, CERTIFICATE
         REGISTRAR, THE MASTER SERVICER, THE SECURITIES ADMINISTRATOR,
         CERTIFICATE REGISTRAR OR THE TRUSTEE.

The following legend shall be placed upon the Class I-B-4, Class I-B-5, Class
I-B-6, Class II-B-4, Class II-B-5 and Class II-B-6 Certificates, whether upon
original issuance or upon issuance of any other Certificate of any such Class in
exchange therefor or upon transfer thereof:

         THIS CERTIFICATE MAY NOT BE ACQUIRED DIRECTLY OR INDIRECTLY BY, OR ON
BEHALF OF, AN EMPLOYEE BENEFIT PLAN OR OTHER RETIREMENT ARRANGEMENT WHICH IS
SUBJECT TO TITLE I OF THE EMPLOYEE RETIREMENT INCOME SECURITY ACT OF 1974, AS
AMENDED, OR SECTION 4975 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED,
UNLESS THE TRANSFEREE CERTIFIES OR REPRESENTS THAT THE PROPOSED TRANSFER AND
HOLDING OF A CERTIFICATE AND THE SERVICING, MANAGEMENT AND OPERATION OF THE
TRUST AND ITS ASSETS: (I) WILL NOT RESULT IN ANY PROHIBITED TRANSACTION WHICH IS
NOT COVERED UNDER AN INDIVIDUAL OR CLASS PROHIBITED TRANSACTION EXEMPTION,
INCLUDING, BUT NOT LIMITED TO, PROHIBITED TRANSACTION EXEMPTION ("PTE") 84-14,
PTE 91-38, PTE 90-1, PTE 95-60 OR PTE 96-23 AND (II) WILL NOT GIVE RISE TO ANY
ADDITIONAL OBLIGATIONS ON THE PART OF THE DEPOSITOR, THE SECURITIES
ADMINISTRATOR, THE MASTER SERVICER, CERTIFICATE REGISTRAR OR THE TRUSTEE, WHICH
WILL BE DEEMED REPRESENTED BY AN OWNER OF A BOOK-ENTRY CERTIFICATE OR A GLOBAL
CERTIFICATE OR UNLESS THE OPINION SPECIFIED IN SECTION 5.07 OF THE AGREEMENT IS
PROVIDED.

         Section 5.02 REGISTRATION OF TRANSFER AND EXCHANGE OF CERTIFICATES.

         (a) The Certificate Registrar shall maintain at its Corporate Trust
Office a separate Certificate Register for Certificates in which, subject to
such reasonable regulations as it may prescribe, the Certificate Registrar shall
provide for the registration of the related Certificates and of transfers and
exchanges of the related Certificates as herein provided.

         (b) Subject to Subsection 5.01(a) and, in the case of any Global
Certificate or Physical Certificate upon the satisfaction of the conditions set
forth below, upon surrender for registration of transfer of any Certificate at
any office or agency of the Certificate Registrar maintained for such purpose,
the Certificate Registrar shall sign, countersign and shall deliver, in the name
of the designated transferee or transferees, a new Certificate of a like Class
and aggregate Fractional Undivided Interest, but bearing a different number.

         (c) By acceptance of an Individual Certificate, whether upon original
issuance or subsequent transfer, each holder of such a Certificate acknowledges
the restrictions on the transfer of such Certificate set forth in the Securities
Legend and agrees that it will transfer such a Certificate only as provided
herein. In addition to the provisions of Subsection 5.02(h), the following
restrictions shall apply with respect to the transfer and registration of
transfer of an Individual Certificate to a transferee that takes delivery in the
form of an Individual Certificate:

                  (i) The Certificate Registrar shall register the transfer of
an Individual Certificate if the requested transfer is being made to a
transferee who has provided the Certificate Registrar with a Rule 144A
Certificate or comparable evidence as to its QIB status.

                  (ii) The Certificate Registrar shall register the transfer of
any Individual Certificate if (x) the transferor has advised the Certificate
Registrar in writing that the Certificate is being transferred to an
Institutional Accredited Investor; and (y) prior to the transfer the transferee
furnishes to the Certificate Registrar an Investment Letter (and the Certificate
Registrar shall be fully protected in so doing), provided that, if based upon an
Opinion of Counsel addressed to the Certificate Registrar to the effect that the
delivery of (x) and (y) above are not sufficient to confirm that the proposed
transfer is being made pursuant to an exemption from, or in a transaction not
subject to, the registration requirements of the Securities Act and other
applicable laws, the Certificate Registrar shall as a condition of the
registration of any such transfer require the transferor to furnish such other
certifications, legal opinions or other information prior to registering the
transfer of an Individual Certificate as shall be set forth in such Opinion of
Counsel.

         (d) Subject to Subsection 5.02(h), so long as a Global Certificate of
such Class is outstanding and is held by or on behalf of the Depository,
transfers of beneficial interests in such Global Certificate, or transfers by
holders of Individual Certificates of such Class to transferees that take
delivery in the form of beneficial interests in the Global Certificate, may be
made only in accordance with this Subsection 5.02(d) and in accordance with the
rules of the Depository:

                  (i) In the case of a beneficial interest in the Global
Certificate being transferred to an Institutional Accredited Investor, such
transferee shall be required to take delivery in the form of an Individual
Certificate or Certificates and the Certificate Registrar shall register such
transfer only upon compliance with the provisions of Subsection 5.02(c)(ii).

                  (ii) In the case of a beneficial interest in a Class of Global
Certificates being transferred to a transferee that takes delivery in the form
of an Individual Certificate or Certificates of such Class, except as set forth
in clause (i) above, the Certificate Registrar shall register such transfer only
upon compliance with the provisions of Subsection 5.02(c)(i).

                  (iii) In the case of an Individual Certificate of a Class
being transferred to a transferee that takes delivery in the form of a
beneficial interest in a Global Certificate of such Class, the Certificate
Registrar shall register such transfer if the transferee has provided the
Certificate Registrar with a Rule 144A Certificate or comparable evidence as to
its QIB status.

                  (iv) No restrictions shall apply with respect to the transfer
or registration of transfer of a beneficial interest in the Global Certificate
of a Class to a transferee that takes delivery in the form of a beneficial
interest in the Global Certificate of such Class; provided that each such
transferee shall be deemed to have made such representations and warranties
contained in the Rule 144A Certificate as are sufficient to establish that it is
a QIB.

         (e) Subject to Subsection 5.02(h), an exchange of a beneficial interest
in a Global Certificate of a Class for an Individual Certificate or Certificates
of such Class, an exchange of an Individual Certificate or Certificates of a
Class for a beneficial interest in the Global Certificate of such Class and an
exchange of an Individual Certificate or Certificates of a Class for another
Individual Certificate or Certificates of such Class (in each case, whether or
not such exchange is made in anticipation of subsequent transfer, and, in the
case of the Global Certificate of such Class, so long as such Certificate is
outstanding and is held by or on behalf of the Depository) may be made only in
accordance with this Subsection 5.02(e) and in accordance with the rules of the
Depository:

                  (i) A holder of a beneficial interest in a Global Certificate
of a Class may at any time exchange such beneficial interest for an Individual
Certificate or Certificates of such Class.

                  (ii) A holder of an Individual Certificate or Certificates of
a Class may exchange such Certificate or Certificates for a beneficial interest
in the Global Certificate of such Class if such holder furnishes to the
Certificate Registrar a Rule 144A Certificate or comparable evidence as to its
QIB status.

                  (iii) A holder of an Individual Certificate of a Class may
exchange such Certificate for an equal aggregate principal amount of Individual
Certificates of such Class in different authorized denominations without any
certification.

         (f) (i) Upon acceptance for exchange or transfer of an Individual
Certificate of a Class for a beneficial interest in a Global Certificate of such
Class as provided herein, the Certificate Registrar shall cancel such Individual
Certificate and shall (or shall request the Depository to) endorse on the
schedule affixed to the applicable Global Certificate (or on a continuation of
such schedule affixed to the Global Certificate and made a part thereof) or
otherwise make in its books and records an appropriate notation evidencing the
date of such exchange or transfer and an increase in the certificate balance of
the Global Certificate equal to the certificate balance of such Individual
Certificate exchanged or transferred therefor.

                  (ii) Upon acceptance for exchange or transfer of a beneficial
interest in a Global Certificate of a Class for an Individual Certificate of
such Class as provided herein, the Certificate Registrar shall (or shall request
the Depository to) endorse on the schedule affixed to such Global Certificate
(or on a continuation of such schedule affixed to such Global Certificate and
made a part thereof) or otherwise make in its books and records an appropriate
notation evidencing the date of such exchange or transfer and a decrease in the
certificate balance of such Global Certificate equal to the certificate balance
of such Individual Certificate issued in exchange therefor or upon transfer
thereof.

         (g) The Securities Legend shall be placed on any Individual Certificate
issued in exchange for or upon transfer of another Individual Certificate or of
a beneficial interest in a Global Certificate.

         (h) Subject to the restrictions on transfer and exchange set forth in
this Section 5.02, the holder of any Individual Certificate may transfer or
exchange the same in whole or in part (in an initial certificate balance equal
to the minimum authorized denomination set forth in Section 5.01(g) above or any
integral multiple of $1.00 in excess thereof) by surrendering such Certificate
at the Corporate Trust Office, or at the office of any transfer agent, together
with an executed instrument of assignment and transfer satisfactory in form and
substance to the Certificate Registrar in the case of transfer and a written
request for exchange in the case of exchange. The holder of a beneficial
interest in a Global Certificate may, subject to the rules and procedures of the
Depository, cause the Depository (or its nominee) to notify the Certificate
Registrar in writing of a request for transfer or exchange of such beneficial
interest for an Individual Certificate or Certificates. Following a proper
request for transfer or exchange, the Certificate Registrar shall, within five
Business Days of such request made at the Corporate Trust Office, sign,
countersign and deliver at the Corporate Trust Office, to the transferee (in the
case of transfer) or holder (in the case of exchange) or send by first class
mail at the risk of the transferee (in the case of transfer) or holder (in the
case of exchange) to such address as the transferee or holder, as applicable,
may request, an Individual Certificate or Certificates, as the case may require,
for a like aggregate Fractional Undivided Interest and in such authorized
denomination or denominations as may be requested. The presentation for transfer
or exchange of any Individual Certificate shall not be valid unless made at the
Corporate Trust Office by the registered holder in person, or by a duly
authorized attorney-in-fact.

         (i) At the option of the Certificateholders, Certificates may be
exchanged for other Certificates of authorized denominations of a like Class and
aggregate Fractional Undivided Interest, upon surrender of the Certificates to
be exchanged at the Corporate Trust Office; provided, however, that no
Certificate may be exchanged for new Certificates unless the original Fractional
Undivided Interest represented by each such new Certificate (i) is at least
equal to the minimum authorized denomination or (ii) is acceptable to the
Depositor as indicated to the Certificate Registrar in writing. Whenever any
Certificates are so surrendered for exchange, the Certificate Registrar shall
sign and countersign and the Certificate Registrar shall deliver the
Certificates which the Certificateholder making the exchange is entitled to
receive.

         (j) If the Certificate Registrar so requires, every Certificate
presented or surrendered for transfer or exchange shall be duly endorsed by, or
be accompanied by a written instrument of transfer, with a signature guarantee,
in form satisfactory to the Certificate Registrar, duly executed by the holder
thereof or his or her attorney duly authorized in writing.

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

         (l) The Certificate Registrar shall cancel all Certificates surrendered
for transfer or exchange but shall retain such Certificates in accordance with
its standard retention policy or for such further time as is required by the
record retention requirements of the Securities Exchange Act of 1934, as
amended, and thereafter may destroy such Certificates.

         Section 5.03 MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.

         (a) If (i) any mutilated Certificate is surrendered to the Certificate
Registrar, or the Certificate Registrar receives evidence to its satisfaction of
the destruction, loss or theft of any Certificate, and (ii) there is delivered
to the Certificate Registrar such security or indemnity as it may require to
save it harmless, and (iii) the Certificate Registrar has not received notice
that such Certificate has been acquired by a third Person, the Certificate
Registrar shall sign, countersign and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
tenor and Fractional Undivided Interest but in each case bearing a different
number. The mutilated, destroyed, lost or stolen Certificate shall thereupon be
canceled of record by the Certificate Registrar and shall be of no further
effect and evidence no rights.

         (b) Upon the issuance of any new Certificate under this Section 5.03,
the Certificate Registrar may require the payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the fees and expenses of the Certificate
Registrar) connected therewith. Any duplicate Certificate issued pursuant to
this Section 5.03 shall constitute complete and indefeasible evidence of
ownership in the Trust Fund, as if originally issued, whether or not the lost,
stolen or destroyed Certificate shall be found at any time.

         Section 5.04 PERSONS DEEMED OWNERS.

         Prior to due presentation of a Certificate for registration of
transfer, the Depositor, the Paying Agent, the Certificate Registrar or the
Trustee and any agent of the Depositor, the Paying Agent, the Certificate
Registrar or the Trustee may treat the Person in whose name any Certificate is
registered as the owner of such Certificate for the purpose of receiving
distributions pursuant to Section 6.01 and for all other purposes whatsoever.
None of the Depositor, the Paying Agent, the Certificate Registrar or the
Trustee or any agent of the Depositor, the Paying Agent, the Certificate
Registrar or the Trustee shall be affected by notice to the contrary. No
Certificate shall be deemed duly presented for a transfer effective on any
Record Date unless the Certificate to be transferred is presented no later than
the close of business on the third Business Day preceding such Record Date.

         Section 5.05 TRANSFER RESTRICTIONS ON RESIDUAL CERTIFICATES.

         (a) Residual Certificates, or interests therein, may not be transferred
without the prior express written consent of the Tax Matters Person and the
Depositor. As a prerequisite to such consent, (1) the proposed transferee must
provide the Tax Matters Person, the Depositor, the Certificate Registrar and the
Trustee with an affidavit that the proposed transferee is a Permitted Transferee
(and an affidavit that it is a United States Person), and (2) the proposed
transferor must provide the Tax Matters Person, the Depositor, the Certificate
Registrar and the Trustee with a certificate to the effect that it has no
knowledge that the statements made by the proposed transferee in any such
affidavit are false, each as provided in Subsection 5.05(b).

         (b) No transfer, sale or other disposition of a Residual Certificate
(including a beneficial interest therein) may be made unless, prior to the
transfer, sale or other disposition of a Residual Certificate, the proposed
transferee (including the initial purchasers thereof) delivers to the Tax
Matters Person, the Trustee, the Certificate Registrar and the Depositor an
affidavit in the form attached hereto as Exhibit E stating, among other things,
that as of the date of such transfer (i) such transferee is a Permitted
Transferee and that (ii) such transferee is not acquiring such Residual
Certificate for the account of any Person who is not a Permitted Transferee, and
(2) the proposed transferor delivers to the Tax Matters Person, the Trustee, the
Certificate Registrar and the Depositor a certificate to the effect that it has
no knowledge that the statements made by the proposed transferee in any such
affidavit are false. The Tax Matters Person shall not consent to a transfer of a
Residual Certificate if it has actual knowledge that any statement made in the
affidavit issued pursuant to the preceding sentence is not true. Notwithstanding
any transfer, sale or other disposition of a Residual Certificate to any Person
who is not a Permitted Transferee or a United States Person, such transfer, sale
or other disposition shall be deemed to be of no legal force or effect
whatsoever and such Person shall not be deemed to be a Holder of a Residual
Certificate for any purpose hereunder, including, but not limited to, the
receipt of distributions thereon. If any purported transfer shall be in
violation of the provisions of this Subsection 5.05(b), then the prior Holder
thereof shall, upon discovery that the transfer of such Residual Certificate was
not in fact permitted by this Subsection 5.05(b), be restored to all rights and
obligations as a Holder thereof retroactive to the date of the purported
transfer. None of the Trustee, the Certificate Registrar, the Tax Matters Person
or the Depositor shall be under any liability to any Person for any registration
or transfer of a Residual Certificate that is not permitted by this Subsection
5.05(b) or for making payments due on such Residual 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 written affidavit referred
to above was received with respect to such transfer, and the Tax Matters Person,
the Trustee, the Certificate Registrar and the Depositor, as applicable, had no
knowledge that it was untrue. The prior Holder shall be entitled to recover from
any purported Holder of a Residual Certificate that was in fact not a Permitted
Transferee or a United States Person under this Subsection 5.05(b) at the time
it became a Holder all payments made on such Residual Certificate. Each Holder
of a Residual Certificate, by acceptance thereof, shall be deemed for all
purposes to have consented to the provisions of this Subsection 5.05(b) and to
any amendment of this Agreement deemed necessary (whether as a result of new
legislation or otherwise) by counsel of the Tax Matters Person or the Depositor
to ensure that the Residual Certificates are not transferred to any Person who
is not a Permitted Transferee or a United States Person and that any transfer of
such Residual Certificates will not cause the imposition of a tax upon the Trust
or cause any REMIC to fail to qualify as a REMIC.

         (c) The Residual Certificates (including a beneficial interest therein)
may not be purchased by or transferred to any Person who is not a United States
Person.

         (d) By accepting a Residual Certificate, the purchaser thereof agrees
to be a Tax Matters Person, and appoints the Securities Administrator to act as
its agent with respect to all matters concerning the tax obligations of the
Trust.

         Section 5.06 RESTRICTIONS ON TRANSFERABILITY OF NON-OFFERED
CERTIFICATES.

         (a) No offer, sale, transfer or other disposition (including pledge) of
any Non-Offered Certificate shall be made by any Holder thereof unless
registered under the Securities Act, or an exemption from the registration
requirements of the Securities Act and any applicable state securities or "Blue
Sky" laws is available and the prospective transferee (other than the Depositor)
of such Certificate signs and delivers to the Certificate Registrar an
Investment Letter, if the transferee is an Institutional Accredited Investor, in
the form set forth as Exhibit F-l hereto, or a Rule 144A Certificate, if the
transferee is a QIB, in the form set forth as Exhibit F-2 hereto.
Notwithstanding the provisions of the immediately preceding sentence, no
restrictions shall apply with respect to the transfer or registration of
transfer of a beneficial interest in any Non-Offered Certificate that is a
Global Certificate of a Class to a transferee that takes delivery in the form of
a beneficial interest in the Global Certificate of such Class provided that each
such transferee shall be deemed to have made such representations and warranties
contained in the Rule 144A Certificate as are sufficient to establish that it is
a QIB. In the case of a proposed transfer of any Certificate to a transferee
other than a QIB, the Certificate Registrar may require an Opinion of Counsel
addressed to the Certificate Registrar that such transaction is exempt from the
registration requirements of the Securities Act. The cost of such opinion shall
not be an expense of the Certificate Registrar or the Trust Fund.

         (b) The Non-Offered Certificates shall each bear a Securities Legend.

Certificates or Non-Offered Certificates may be acquired directly or indirectly
by, or on behalf of, an employee benefit plan or other retirement arrangement
which is subject to Title I of ERISA or Section 4975 of the Code, unless the
proposed transferee provides either (i) the Certificate Registrar, with an
Opinion of Counsel addressed to the Depositor, the Trustee, the Certificate
Registrar, the Master Servicer and the Securities Administrator (upon which they
may rely) which is satisfactory to the Certificate Registrar, which opinion will
not be at the expense of the Depositor, the Trustee, the Certificate Registrar,
the Master Servicer or the Securities Administrator, that the purchase of such
Certificates by or on behalf of such Plan is permissible under applicable law,
will not constitute or result in a nonexempt prohibited transaction under ERISA
or Section 4975 of the Code and will not subject the Depositor, the Master
Servicer, the Certificate Registrar, the Securities Administrator or the Trustee
to any obligation in addition to those undertaken in the Agreement or (ii) in
the case of the Non-Offered Certificates, a representation or certification to
the Certificate Registrar (upon which the Trustee, the Certificate Registrar and
the other parties hereto are authorized to rely) to the effect that the proposed
transfer and holding of such a Certificate and the servicing, management and
operation of the Trust: (I) will not result in a prohibited transaction under

Non-Offered Certificates, either: (i) it is not acquiring an interest in such
Certificate directly or indirectly by, or on behalf of, an employee benefit plan
or other retirement arrangement which is subject to Title I of ERISA or Section
4975 of the Code, or (ii) the transfer and holding of an interest in such
Certificate to that Person and the subsequent servicing, management and
operation of the Trust and its assets: (I) will not result in any prohibited
transaction which is not covered under an individual or class prohibited
transaction exemption, including, but not limited to, PTE 84-14, PTE 91-38, PTE
90-1, PTE 95-60 or PTE 96-23 and (II) will not subject the Depositor, the
Securities Administrator, the Certificate Registrar, the Master Servicer or the
Trustee to any obligation in addition to those undertaken in the Agreement.

         (c) Each beneficial owner of a Class I-B-1, Class I-B-2, Class I-B-3,
Class II-B-1, Class II-B-2 or Class II-B-3 Certificate or any interest therein

         (d) Neither the Trustee, the Certificate Registrar, the Master Servicer
nor the Securities Administrator will be required to monitor, determine or
inquire as to compliance with the transfer restrictions in this Agreement with
respect to the Book-Entry Certificates. Any attempted or purported transfer of
any Certificate in violation of the provisions of this Agreement shall be void
ab initio and such Certificate shall be considered to have been held
continuously by the prior permitted Certificateholder. Any transferor of any
Certificate in violation of such provisions, shall indemnify and hold harmless
the Trustee, the Certificate Registrar, the Securities Administrator and the
Master Servicer from and against any and all liabilities, claims, costs or
expenses incurred by the Trustee, the Certificate Registrar, the Securities
Administrator or the Master Servicer as a result of such attempted or purported
transfer. Neither the Trustee nor the Certificate Registrar shall be liable for
transfer of any such Book-Entry Certificates in or through book-entry facilities
of any Depository or between or among Depository Participants or Certificate
Owners made in violation of the transfer restrictions set forth herein.

Rule 144A(d)(4) under the Securities Act; and (2) the Depositor shall update
such information from time to time in order to prevent such information from
becoming false and misleading and will take such other actions as are necessary
to ensure that the safe harbor exemption from the registration requirements of
the Securities Act under Rule 144A is and will be available for resales of such
Certificates conducted in accordance with Rule 144A.

                           Principal Distribution Amount, in the order described

         FOURTH above over (y) the sum of the amount of Accrued Certificate
         Interest for such Distribution Date and Accrued Certificate Interest

Class or Classes of Group I Senior Certificates in the remaining Subgroups
(other than the Class I-X Certificates and Class I-PO Certificates) will be
entitled to receive in reduction of their Current Principal Amounts, pro rata
based upon their Current Principal Amounts immediately prior to such
Distribution Date, in addition to any Principal Prepayments related to such
remaining Group I Senior Certificates' respective Subgroup allocated to such
Group I Senior Certificates, 100% of the Principal Prepayments on any Mortgage
Loan in the Subgroup or Subgroups relating to the Class or Classes of Group I
Senior Certificates of the fully repaid Subgroup; provided, however, if (A) the
weighted average of the Subgroup Subordinate Percentages on such Distribution
Date equals or exceeds two times the initial weighted average of the Subgroup
Subordinate Percentages and (B) the aggregate Scheduled Principal Balance of the
Mortgage Loans in Loan Group I delinquent 60 days or more (including for this
purpose any such Mortgage Loans in foreclosure and bankruptcy and Mortgage Loans
with respect to which the related mortgaged property has been acquired by the
trust), averaged over the last six months, as a percentage of the aggregate
Current Principal Amount of the Group I Subordinate Certificates does not exceed
50%, then the additional allocation of Principal Prepayments to the Subgroup I-1

                  (iv) If on any Distribution Date on which the aggregate
Current Principal Amount of the Subgroup I-1 Certificates, Subgroup I-2
Certificates and Subgroup I-3 Certificates would be greater than the aggregate
Scheduled Principal Balance of the Mortgage Loans in its related Subgroup and
any Group I Subordinate Certificates are still outstanding, in each case, after
giving effect to distributions to be made on such Distribution Date, (i) 100% of
amounts otherwise allocable to the Group I Subordinate Certificates in respect
of principal will be distributed to the Subgroup I-1 Certificates, Subgroup I-2
Certificates and Subgroup I-3 Certificates (other than the Class I-X
Certificates and Class I-PO Certificates), pro rata, based upon their Current
Principal Amounts immediately prior to such Distribution Date, in reduction of
the Current Principal Amounts thereof, until the aggregate Current Principal
Amount of the Subgroup I-1 Certificates, Subgroup I-2 Certificates and Subgroup
I-3 Certificates, as applicable, is equal to the aggregate Scheduled Principal
Balance of the Mortgage Loans in its related Subgroup, and (ii) the Accrued
Certificate Interest otherwise allocable to the Group I Subordinate Certificates
on such Distribution Date will be reduced, if necessary, and distributed to such
class or classes of Group I Senior Certificates in an amount equal to the
Accrued Certificate Interest for such Distribution Date on the excess of (x) the
aggregate Current Principal Amount of the Subgroup I-1 Certificates, Subgroup
I-2 Certificates and Subgroup I-3 Certificates (other than the Class I-X, Class
I-XB and Class I-PO Certificates), as applicable, over (y) the aggregate
Scheduled Principal Balance of the Mortgage Loans in the related Subgroup. Any
such reduction in the Accrued Certificate Interest on the Group I Subordinate
Certificates will be allocated in reverse order of the Group I Subordinate
Certificates' numerical designations, commencing with the Class I-B-6
Certificates.

Principal Distribution Amount, or the remaining Group I Available Funds related
to Subgroup I-2 is less than the Subgroup I-2 Principal Distribution Amount, or

Subgroup I-3 Principal Distribution Amount, such amounts shall be reduced, and
such remaining funds will be distributed to the related Group I Senior
Certificates (other than the Class I-X Certificates) on the basis of such
reduced amounts. Notwithstanding any reduction in principal distributable to the
Class I-PO Certificates pursuant to this paragraph, the principal balance of the
Class I-PO Certificates shall be reduced not only by principal so distributed
but also by the Class I-PO Certificate Cash Shortfall. The Class I-PO
Certificate Cash Shortfall for the Class I-PO Certificates with respect to any
Distribution Date will be added to the Class I-PO Certificate Deferred Amount.

         On each Distribution Date, any Group I Available Funds remaining after
payment of interest and principal to the Classes of Certificates entitled
thereto, in each case as described above, will be distributed to the Class I-R-1
Certificates; provided that, if on any Distribution Date there are any Group I
Available Funds remaining after payment of interest and principal to a Class or
Classes of Certificates entitled thereto, such amounts will be distributed to
the other Classes of Group I Senior Certificates, pro rata, based upon their
Current Principal Amounts, until all amounts due to all Classes of Group I
Senior Certificates have been paid in full, before any amounts are distributed
to the Class I-R-1 Certificates.

         (II) DISTRIBUTIONS ON THE GROUP II CERTIFICATES:

         extent of the remaining Group II Available Funds until the Current
          Principal Amount of each such Class has been reduced to zero;

                  FOURTH, to the Class II-PO Certificates, the Class II-PO
         Certificate Principal Distribution Amount for such Distribution Date to
         the extent of the remaining Group II Available Funds, until the Current
         Principal Amount thereof has been reduced to zero; and

                  FIFTH, to the Class II-PO Certificates, the Class II-PO
         Certificate Deferred Amount; provided that, (i) on any Distribution
         Date, distributions pursuant to this priority FIFTH shall not exceed
         the excess, if any, of (x) Group II Available Funds remaining after
         giving effect to distributions pursuant to priorities FIRST through
         FOURTH above over (y) the sum of the amount of Accrued Certificate
         Interest for such Distribution Date and Accrued Certificate Interest
         remaining undistributed from previous Distribution Dates on all classes
         of Group II Subordinate Certificates then outstanding, (ii) such
         distributions shall not reduce the Current Principal Amount of the

         respect of the Class II-PO Certificate Deferred Amount on or after the
         Group II Cross-Over Date.

                  (ii) On each Distribution Date prior to the Group II
Cross-Over Date, an amount equal to the remaining Group II Available Funds after
the distributions in clause (i) above will be distributed sequentially in the
following order, to the Class II-B-1, Class II-B-2, Class II-B-3, Class II-B-4,
Class II-B-5 and Class II-B-6 Certificates, in each case up to an amount equal
to and in the following order: (a) the Accrued Certificate Interest thereon for
such Distribution Date, (b) any Accrued Certificate Interest thereon remaining
undistributed from previous Distribution Dates and (c) such Class's Group II
Allocable Share for such Distribution Date, in each case, to the extent of the
remaining Group II Available Funds.

                  (iii) If, after distributions have been made pursuant to
priorities FIRST and SECOND of clause (i) above on any Distribution Date, the
remaining Group II Available Funds are less than the Group II Senior Optimal
Principal Amount and Class II-PO Certificate Principal Distribution Amount, such
amounts shall be reduced, and such remaining funds will be distributed to the
Group II Senior Certificates (other than the Class II-X Certificates) on the
basis of such reduced amounts. Notwithstanding any reduction in principal
distributable to the Class II-PO Certificates pursuant to this paragraph, the
Current Principal Amount of the Class II-PO Certificates shall be reduced not
only by principal so distributed but also by the Class II-PO Certificate Cash
Shortfall. The Class II-PO Certificate Cash Shortfall for the Class II-PO
Certificates with respect to any Distribution Date will be added to the Class
II-PO Certificate Deferred Amount.

                  (iv) On or after the occurrence of the Group II Cross-Over
Date, all priorities relating to distributions as described above in respect of
principal among the various classes of related Senior Certificates (other than
the Class II-PO Certificates) will be disregarded, and the remaining Group II
Available Funds will be distributed to such Certificates (other than the Class
II-PO Certificates) pro rata in accordance with their respective outstanding
Certificate Principal Balances and an amount equal to the Class II-PO
Certificate Principal Distribution Amount will be distributed to the Class II-PO
Certificates.

         On each Distribution Date, any Group II Available Funds remaining after
payment of interest and principal to the Classes of Certificates entitled
thereto, in each case as described above, will be distributed to the Class
II-R-1 Certificates; provided, that if on any Distribution Date there are any
Group II Available Funds remaining after payment of interest and principal to a
Class or Classes of Certificates entitled thereto, such amounts will be
distributed to the other Class or Classes of Group II Senior Certificates, pro
rata, based upon their Current Principal Amounts, until all amounts due to all
Classes of Group II Senior Certificates have been paid in full, before any
amounts are distributed to the Class II-R-1 Certificates.

         (b) "Pro rata" distributions among Classes of Certificates will be made
in proportion to the then Current Principal Amount of such Classes.

         (c) No Accrued Certificate Interest will be payable with respect to any
Class of Certificates after the Distribution Date on which the Current Principal
Amount or Notional Amount of such Certificate has been reduced to zero.

         (d) If on any Distribution Date the Available Funds for the related
Senior Certificates is less than the Accrued Certificate Interest on the related
Senior Certificates for such Distribution Date pr
