     These Stack I Pooling and Servicing Terms are dated as of October 1, 2006
(the "Agreement," and, together with the Stack II Pooling and Servicing Terms
(the "Stack II Agreement") dated as of October 1, 2006, the "Pooling and
Servicing Agreement"), among MERRILL LYNCH MORTGAGE INVESTORS, INC., as

capacity, the "Master Servicer") and as securities administrator (in such
capacity, the "Securities Administrator") and HSBC BANK USA, NATIONAL

                              PRELIMINARY STATEMENT

     The Depositor has acquired the Mortgage Loans from the Seller and at the
Closing Date is the owner of the Mortgage Loans and the other related property
being conveyed by the Depositor to the Trustee hereunder on behalf of the
Issuing Entity for inclusion in the Trust Fund. On the Closing Date, the
Depositor will acquire the Certificates from the Securities Administrator as
consideration for the Depositor's transfer to the Issuing Entity of the Mortgage
Loans and the other related property constituting that portion of the Trust Fund
relating to the Certificates. The Depositor has duly authorized the execution
and delivery of this Agreement to provide for the conveyance to the Issuing
Entity of the Mortgage Loans and the other related property constituting that
portion of the Trust Fund relating to the Certificates. All covenants and
agreements made by the Transferor in the Transfer Agreement, the Seller in the
Mortgage Loan Purchase Agreement and in this Agreement and all covenants and
agreements made by the Depositor, the Trustee, the Securities Administrator and
the Master Servicer herein with respect to the Mortgage Loans and the other
related property constituting the portion of the Trust Fund relating to the
Certificates are for the benefit of the Holders from time to time of the
Certificates. The Depositor, the Trustee, the Securities Administrator and the
Master Servicer are entering into this Agreement, and the Trustee on behalf of
the Issuing Entity is accepting the Trust Fund created hereby, for good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged.

     In conjunction herewith, the Depositor has acquired the Stack II Mortgage
Loans from the Seller and at the Closing Date is the owner of the Stack II
Mortgage Loans and the other related property being conveyed by the Depositor to
the Trustee under the Stack II Agreement on behalf of the Issuing Entity for
inclusion in the Trust Fund. On the Closing Date, the Depositor will acquire the
Stack II Certificates from the Securities Administrator as consideration for the
Depositor's transfer to the Issuing Entity of the Stack II Mortgage Loans and
the other related property constituting that portion of the Trust Fund relating
to the Stack II Certificates. The Depositor has duly authorized the execution
and delivery of the Stack II Agreement to provide for the conveyance to the
Issuing Entity of the Stack II Mortgage Loans and the other related property
constituting that portion of the Trust Fund relating to the Stack II
Certificates. The terms and conditions relating to the issuance of the Stack II
Certificates are set forth in the Stack II Agreement.

      As provided herein, the Securities Administrator shall elect that that
portion of the Trust Fund relating to Stack I be treated for federal income tax
purposes as comprising a real estate mortgage investment conduit (a "REMIC" or,
in the alternative, the "Upper Tier REMIC,"

<PAGE>

respectively). The Certificates created under this Agreement shall represent
ownership of regular interests in the Upper Tier REMIC.

     The Upper Tier REMIC shall hold as its assets the property of the Trust
Fund relating to Stack I.

     Each Upper Tier REMIC Regular Interest is hereby designated as a regular
interest in the Upper Tier REMIC for purposes of the REMIC Provisions.

     The Class UT-R Interest is hereby designated as the sole class of residual
interest in the Upper Tier REMIC for purposes of the REMIC Provisions. The Class
A-R Certificate shall represent the Class UT-R Interest and the residual
interest in any REMIC created under the Stack II Agreement.

delivered to it and to execute and deliver, or cause to be executed and
delivered, to the Depositor on the Closing Date an Initial Certification. In
conducting such review, the Trustee or Custodian will certify as to each
Mortgage Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan
paid in full or any Mortgage Loan specifically identified in the exception
report annexed thereto as not being covered by such certification), (i) all
documents constituting part of such Mortgage File (other than such documents
described in Section 2.01(b)(iii)) required to be delivered to it pursuant to
this Agreement are in its possession, provided that with respect to the
documents described in Section 2.01(b)(v), (vi), (viii) and (ix) to the extent
the Trustee or the Custodian on its behalf has actual knowledge that such
documents exist, (ii) such documents have been reviewed by it and are not torn,
mutilated, defaced or otherwise altered (except if initialed by the obligor) and
appear to relate on their face to such Mortgage Loan, (iii) based on its
examination and only as to the foregoing, the information set forth in the
Mortgage Loan Schedule corresponding to the loan number for the Mortgage Loan,
the Mortgagor's name, including the street address but excluding the zip code,
the Mortgage Interest Rate and the original principal balance of the Mortgage
Loan accurately reflects information set forth in the Mortgage File and (iv)
with respect to Mortgage Loans with a Mortgage Interest Rate subject to
adjustment, the gross margin, the lifetime cap and the periodic cap for such
Mortgage Loan. 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.
Notwithstanding anything to the contrary in this Agreement, it is herein
acknowledged that, in conducting such review, the Trustee or the Custodian on
its behalf is under no duty or obligation to inspect, review or examine any such
documents, instruments, certificates or other papers to determine whether they
are genuine, enforceable, or appropriate for the represented purpose or whether
they have actually been recorded or that they are other than what they purport
to be on their face, or to determine whether any Person executing any documents
is authorized to do so or whether any signature is genuine.

          (b) If the Trustee or the Custodian, as its agent, finds any document
constituting part of the Mortgage File not to have been executed or received, or
to be unrelated to the Mortgage Loans identified in Exhibit B or to appear to be
defective on its face, the Trustee or the Custodian, as its agent, shall
promptly notify the Seller. In accordance with the Transfer Agreement, the
Transferor 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 Transferor fails to correct or cure the defect within such
period, and such defect materially and adversely affects the interests of the
Certificateholders in the related Mortgage Loan, the Trustee, shall enforce the
Transferor's obligation pursuant to the Transfer Agreement, within 90 days from
the Trustee's or the Custodian's notification, to purchase such Mortgage Loan at
the Purchase 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 Transferor 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 Transferor shall not be required to purchase such Mortgage
Loan if the Transferor 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
Transferor 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
Transferor 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 Transferor within thirty days
of its receipt of the original recorded document.

          (c) 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 a Final Certification. In conducting
such review, the Trustee or the Custodian, as its agent, will certify as to each
Mortgage Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan
paid in full or any Mortgage Loan specifically identified in the exception
report annexed thereto as not being covered by such certification), that (i) all
documents constituting part of such Mortgage File (other than such documents
described in Section 2.01(b)(v) and (ix)) required to be delivered to it
pursuant to this Agreement are in its possession, provided that with respect to
the documents described in Section 2.01(b)(v), (vi), (viii) and (ix) to the
extent the Trustee or the Custodian on its behalf has actual knowledge that such
documents exist, (ii) such documents have been reviewed by it and are not torn,
mutilated, defaced or otherwise altered (except if initialed by the obligor) and
appear regular on their face and relate to such Mortgage Loan, (iii) based on
its examination and only as to the foregoing, the information set forth in the
Mortgage Loan Schedule corresponding to the loan number for the Mortgage Loan,
the Mortgagor's name, including the street address but excluding the zip code,
the Mortgage Interest Rate and the original principal balance of the Mortgage
Loan accurately reflects information set forth in the Mortgage File. 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.
Notwithstanding anything to the contrary in this Agreement, it is herein
acknowledged that, in


                                       -40-

<PAGE>

conducting such review, the Trustee or the Custodian on its behalf is under no
duty or obligation (i) to inspect, review or examine any such documents,
instruments, certificates or other papers to determine whether they are genuine,
enforceable, or appropriate for the represented purpose or whether they have
actually been recorded or that they are other than what they purport to be on
their face, or to determine whether any Person executing any documents is
authorized to do so or whether any signature is genuine. If the Trustee or the
Custodian, as its agent, finds any document constituting part of the Mortgage
File not to have been executed or received, or to be unrelated to the Mortgage
Loans identified in Exhibit B or to appear to be defective on its face, the
Trustee or the Custodian, as its agent, shall promptly notify the Transferor. In
accordance with the Transfer Agreement, the Transferor shall correct or cure any
such defect within 90 days from the date of notice from the Trustee of the
defect and if the Transferor is unable to cure such defect within such period,
and if such defect materially and adversely affects the interests of the
Certificateholders in the related Mortgage Loan, the Trustee shall enforce the
Transferor's obligation under the Transfer Agreement to purchase such Mortgage
Loan at the Purchase Price, provided, however, that if such defect relates
solely to the inability of the Transferor 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 Transferor shall not be required to purchase such
Mortgage Loan, if the Transferor delivers such original documents or certified
copy promptly upon receipt, but in no event later than 360 days after the
Closing Date.

          (d) In the event that a Mortgage Loan is purchased by the Transferor
in accordance with Subsections 2.02(a) or (b) above, the Transferor shall remit
to the Master Servicer the Purchase Price for deposit in the Master Servicer
Collection Account and the Transferor shall provide to the Trustee written
notification detailing the components of the Purchase Price. Upon deposit of the
Purchase Price in the Master Servicer Collection Account, the Depositor shall
give written notice thereof to the Trustee and the Custodian and the Trustee or
the Custodian, as its agent (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 Transferor the related Mortgage File and the Trustee shall execute and
deliver all instruments of transfer or assignment, without recourse, furnished
to it by the Transferor as are necessary to vest in the Transferor title to and
rights under the Mortgage Loan. Such purchase shall be deemed to have occurred
on the date on which the Purchase Price in available funds is received by the
Trustee. The Depositor or Master Servicer shall amend the Mortgage Loan
Schedule, to reflect such repurchase and shall promptly notify the Rating
Agencies and the Master Servicer of such amendment. The obligation of the
Transferor to repurchase any Mortgage Loan as to which such a defect in a
constituent document exists shall be the sole remedy respecting such defect
available to the 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, all of its right, title and interest in the Mortgage Loan
Purchase Agreement, including but not limited to Depositor's rights pursuant to
the Servicing Agreement (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 Servicer under the Servicing
Agreement to enforce the provisions thereof and to seek all or any available
remedies). The


                                      -41-

<PAGE>

obligations of the Transferor to substitute or repurchase, as applicable, a
Mortgage Loan shall be the Trustee's and the 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 and the Certificateholders or shall execute such further
documents as the Trustee may reasonably require in order to enable the Trustee
to carry out such enforcement. With respect to the representations and
warranties described in the Mortgage Loan Purchase Agreement that are made to
the best of the Transferor's knowledge, if it is discovered by any of the
Depositor, the Transferor, the Master Servicer, the Securities Administrator or
the Trustee that the substance of such representation and warranty is inaccurate
and such inaccuracy materially and adversely affects the value of the related
Mortgage Loan, then notwithstanding the Transferor's lack of knowledge with
respect to the substance of such representation and warranty, such inaccuracy
shall be deemed a breach of the applicable representation or warranty.

          (b) If the Depositor, the Master Servicer, 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 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 Transferor,
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 Transferor shall pay, in lieu of the Purchase Price, any excess of the
Purchase Price over the Net Liquidation Proceeds received upon such sale. (If
the Net Liquidation Proceeds exceed the Purchase Price, any excess shall be paid
to the Transferor to the extent not required by law to be paid to the borrower.)
Any such purchase by the Transferor shall be made by providing an amount equal
to the Purchase Price to the Master Servicer for deposit in the Master Servicer
Collection Account and written notification detailing the components of such
Purchase Price. The Depositor shall notify the Trustee in writing of the deposit
of the Purchase Price and submit to the Trustee or the Custodian, as its agent,
a Request for Release, and the Trustee shall release, or the Trustee shall cause
the Custodian to release, to the Transferor the related Mortgage File and the
Trustee shall execute and deliver all instruments of transfer or assignment
furnished to it by the Transferor, without recourse, as are necessary to vest in
the Transferor 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 Purchase Price in available funds is received by the
Master Servicer. The Depositor or the Master Servicer shall amend the Mortgage
Loan Schedule to reflect such repurchase and shall promptly notify the Master
Servicer and the Rating Agencies of such amendment. Enforcement of the
obligation of the Transferor to purchase (or substitute a Substitute Mortgage
Loan for) any Mortgage Loan or any property acquired with respect thereto (or
pay the Purchase 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.


                                      -42-

<PAGE>

     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 Transferor may, no later than the date by which such purchase by
the Transferor would otherwise be required, tender to the Trustee a Substitute
Mortgage Loan accompanied by a certificate of an authorized officer of the
Transferor that such Substitute Mortgage Loan conforms to the requirements set
forth in the definition of "Substitute Mortgage Loan" in the Mortgage Loan
Purchase Agreement or this Agreement, as applicable; 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 Trustee or the Custodian, as its agent, 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
Transferor, in writing, within five Business Days after receipt, whether or not
the documents relating to the Substitute Mortgage Loan satisfy the requirements
of the fourth sentence of Subsection 2.02(a). Within two Business Days after
such notification, the Transferor shall provide to the Securities Administrator
for deposit in the Distribution 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 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 Transferor of the Purchase Price for
the purchase of a Mortgage Loan by the Transferor. After such notification to
the Transferor and, if any such excess exists, upon written notification of the
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 Issuing Entity 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 Transferor. The Scheduled Principal on a Substitute Mortgage
Loan due on the Due Date in the month of substitution shall be the property of
the Transferor 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 Issuing
Entity. Upon acceptance of the Substitute Mortgage Loan (and delivery to the
Trustee or Custodian of a Request for Release for such Mortgage Loan), the
Trustee shall release to the Transferor 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, in form as provided to
it as are necessary to vest in the Transferor 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 Transferor shall deliver 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


                                      -43-

<PAGE>

Purchase Agreement shall be deemed to have been made by the Transferor 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.

     Notwithstanding any other provision of this Agreement, the right to
substitute Mortgage Loans pursuant to this Article II shall be subject to the
additional limitations that no substitution of a Mortgage Loan shall be made
unless the Securities Administrator and the Trustee shall have received an
Opinion of Counsel (at the expense of the party seeking to make the
substitution) that, under current law, such substitution will not (A) affect
adversely the status of any REMIC established hereunder as a REMIC, or of the
related "regular interests" as "regular interests" in any such REMIC, or (B)
cause any such REMIC to engage in a "prohibited transaction" or prohibited
contribution pursuant to the REMIC provisions.

     Section 2.05. Issuance of Certificates. The Trustee acknowledges the
assignment to it on behalf of the Issuing Entity of the Mortgage Loans and the
other assets comprising the Trust Fund and, concurrently therewith, the
Securities Administrator has signed, and countersigned and delivered to the
Depositor, in exchange therefor, Certificates in such authorized denominations
representing such Percentage 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 Certificateholders.

     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:

               (i) the Depositor (a) is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware and (b) is
qualified and in good standing as a foreign corporation to do business in each
jurisdiction where such qualification is necessary, except where the failure so
to qualify would not reasonably be expected to have a material adverse effect on
the Depositor's business as presently conducted or on the Depositor's ability to
enter into this Agreement and to consummate the transactions contemplated
hereby;

               (ii) 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 obligations under this Agreement;

               (iii) the execution and delivery by the Depositor of this
Agreement have been duly authorized by all necessary corporate action on the
part of the Depositor; and neither the execution and delivery of this Agreement,
nor the consummation of the transactions herein contemplated, nor compliance
with the provisions hereof, will conflict with or result in a breach of, or
constitute a default under, any of the provisions of any law, governmental rule,
regulation, judgment, decree or order binding on the Depositor or its properties
or the 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;


                                       -44-

<PAGE>

               (iv) 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 with, or the taking of any other action in respect of, any state,
federal or other governmental authority or agency, except those consents,
approvals, notices, registrations or other actions as have already been
obtained, given or made;

                (v) this Agreement has been duly executed and delivered by the
Depositor and, assuming due authorization, execution and delivery by the other
parties hereto, constitutes a valid and binding obligation of the Depositor
enforceable against it in accordance with its terms (subject to applicable
bankruptcy and insolvency laws and other similar laws affecting the enforcement
of the rights of creditors generally);

               (vi) there are no actions, suits or proceedings pending or, to
the knowledge of the Depositor, threatened against the Depositor, before or by
any court, administrative agency, arbitrator or governmental body (i) with
respect to any of the transactions contemplated by this Agreement or (ii) with
respect 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, arbitrator or governmental body so as to materially and
adversely affect the transactions contemplated by this Agreement; and

               (vii) immediately prior to the transfer and assignment to the
Trustee, each Mortgage Note and each Mortgage were not subject to an assignment
or pledge, and the Depositor had good and marketable title to and was the sole
owner thereof and had full right to transfer and sell such Mortgage Loan to the
Trustee free and clear of any encumbrance, equity, lien, pledge, charge, claim
or security interest.

     Section 2.07. Representations and Warranties Concerning the Master Servicer
and Securities Administrator. Wells Fargo Bank, N.A., in its capacity as Master
Servicer and Securities Administrator hereby represents and warrants to the
Seller, the Depositor and the Trustee as follows, as of the Closing Date:

               (i) It is a national banking association duly formed, validly
existing and in good standing under the laws of the United States of America and
is duly authorized and qualified to transact any and all business contemplated
by this Agreement to be conducted by the Master Servicer and the Securities
Administrator, to the extent necessary to ensure its ability to master service
the Mortgage Loans in accordance with the terms of this Agreement and to perform
any of its other obligations under this Agreement in accordance with the terms
hereof;

               (ii) It has the full corporate power and authority to execute,

corporate action on its part the execution, delivery and performance of this
Agreement; and this Agreement, assuming the due authorization, execution and
delivery hereof by the other parties hereto, constitutes its legal, valid and
binding obligation, enforceable against it in accordance with its terms, except
that (a) the enforceability hereof may be limited by bankruptcy, insolvency,
moratorium, receivership and other similar laws relating to


                                      -45-

<PAGE>

creditors' rights generally and (b) the remedy of specific performance and
injunctive and other forms of equitable relief may be subject to equitable
defenses and to the discretion of the court before which any proceeding therefor
may be brought.

               (iii) The execution and delivery of this Agreement by it, the
consummation of any other of the transactions contemplated by this Agreement,
and the fulfillment of or compliance with the terms hereof are in its ordinary
course of business and will not (A) result in a material breach of any term or
provision of its charter or by-laws or (B) materially conflict with, result in a
material breach, violation or acceleration of, or result in a material default
under, the terms of any other material agreement or instrument to which it is a
party or by which it may be bound, or (C) constitute a material violation of any
statute, order or regulation applicable to it of any court, regulatory body,
administrative agency or governmental body having jurisdiction over it; and it
is not in breach or violation of any material indenture or other material
agreement or instrument, or in violation of any statute, order or regulation of
any court, regulatory body, administrative agency or governmental body having
jurisdiction over it which breach or violation may materially impair its ability
to perform or meet any of its obligations under this Agreement.

               (iv) No litigation is pending or, to the best of its knowledge,
threatened, against it that would materially and adversely affect the execution,
delivery or enforceability of this Agreement or its ability to perform any of

               (v) No consent, approval, authorization or order of any court or
governmental agency or body is required for its execution, delivery and

authorization or order is required, it has obtained the same.

                                   ARTICLE III.
                 ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

     Section 3.01. Master Servicer. The Master Servicer shall supervise, monitor
and oversee the obligation of the Servicer to service and administer the
Mortgage Loans in accordance with the terms of the Servicing Agreement and shall
have full power and authority to do any and all things which it may deem
necessary or desirable in connection with such master servicing and
administration. In performing its obligations hereunder, the Master Servicer
shall act in a manner consistent with Accepted Master Servicing Practices.
Furthermore, the Master Servicer shall oversee and consult with the 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 the Servicer and shall cause the
Servicer to perform and observe the covenants, obligations and conditions to be
performed or observed by such Servicer under the Servicing Agreement. The Master
Servicer shall independently and separately monitor the 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 Servicer's 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, and


                                      -46-

<PAGE>

prepare any other information and statements required to be forwarded by the
Master Servicer hereunder. The Master Servicer shall reconcile the results of
its monitoring with the actual remittances of the Servicer to the Master
Servicer Collection Account pursuant to the Servicing Agreement.

     If the Master Servicer and the Securities Administrator are the same
entity, then at any time the Master Servicer is terminated as Master Servicer,
the Securities Administrator shall likewise be removed as securities
administrator.

     The Trustee shall furnish the Servicer and the Master Servicer with any
limited powers of attorney and other documents in form acceptable to it
necessary or appropriate to enable the Servicer and the Master Servicer to
service and administer the related Mortgage Loans and REO Property. The Trustee
shall have no liability with respect to the use of any such limited power of
attorney.

     The Trustee or the Custodian shall provide access to the records and
documentation in possession of the Trustee or the Custodian regarding the
related Mortgage Loans and REO Property and the servicing thereof to the
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 or the Custodian;
provided, however, that, unless otherwise required by law, the Trustee or the
Custodian 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 or the Custodian 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 or the
Custodian's actual costs.

     The Trustee shall execute and deliver to the Servicer and the Master
Servicer upon request 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 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 and the Securities Administrator has
received a REMIC Opinion prepared at the expense of the Issuing Entity; 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.

     Section 3.03. Monitoring of Servicer.


                                      -47-

<PAGE>

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

          (b) The Master Servicer, for the benefit of the Trustee and the
Certificateholders, shall enforce the obligations of the Servicer under the
Servicing Agreement, and shall, in the event that the Servicer fails to perform
its obligations in accordance with the 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, if the Master
Servicer is unwilling or unable to act as the Servicer, the Master Servicer
shall cause the Trustee to enter in to a new Servicing Agreement with a
successor Servicer selected by the Master Servicer that is eligible in
accordance with the criteria specified in this Agreement; 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 the Servicing Agreement and the pursuit of other appropriate
remedies, shall be in such form and carried out to such an extent and at such
time as the Master Servicer, in its good faith business judgment, would require
were it the owner of the related Mortgage Loans. The Master Servicer shall pay
the costs of such enforcement at its own expense subject to Section 3.03(c),
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.

          (c) To the extent that the costs and expenses of the Master Servicer
related to any termination of the Servicer, appointment of a successor Servicer
or the transfer and assumption of servicing by the Master Servicer with respect
to the 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
service to service the Mortgage Loans in accordance with the 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 pursuant to Section 4.03(b).

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

          (e) If the Master Servicer acts as Servicer, it will not assume
liability for the representations and warranties of such Servicer, 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
Certificateholders 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 and Liquidation Proceeds, 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 Servicing Agreement, as applicable; provided, however,
that the Master Servicer shall not (and, consistent with its responsibilities
under Section 3.03, shall not permit the 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 REMIC created hereunder to fail to qualify as a
REMIC or result in the imposition of a tax upon the Issuing Entity (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 will not would cause any REMIC created hereunder to fail
to qualify as a REMIC or result in the imposition of a tax upon any REMIC
created hereunder. The Trustee shall furnish the Master Servicer, upon written
request from a Servicing Officer, with any limited powers of attorney (in form
acceptable to the Trustee) empowering the Master Servicer or the Servicer to
execute and deliver instruments of satisfaction or cancellation, or of partial
or full release or discharge, and to foreclose upon or otherwise liquidate
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
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 the 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


                                      -49-

<PAGE>

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 Servicing Agreement, to the extent Mortgage Loans contain
enforceable due-on-sale clauses, the Master Servicer shall cause the Servicer to
enforce such clauses in accordance with the 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 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 the Servicer of a notification that payment in full has been
escrowed in a manner customary for such purposes for payment to
Certificateholders on the next Distribution Date, the Servicer or the Master
Servicer will, if required under the Servicing Agreement, 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 Servicer pursuant to its 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 no
later than five Business Days (or, to the extent that the Servicer notifies the
Seller that a document is not in the Servicer's possession as part of the
servicing file which is needed for purposes of the Servicer complying with any
applicable law, within such shorter period as may be necessary to enable the
Servicer to comply with such law), 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, the 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 Servicing Agreement,
the Trustee shall execute such documents as requested and as shall be prepared
and furnished to the Trustee by the Servicer or the Master Servicer and as are
necessary to the prosecution of any such proceedings. In connection with the
foregoing, the Custodian, on behalf of the Trustee, shall, upon the request of
the 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


                                       -50-

<PAGE>

face, originate from a Servicing Officer), release the related Mortgage File
held in its possession or control to the Servicer or the Master Servicer, as
applicable. 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 the Servicer (to the extent
required by the 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 Servicer, the Servicing Agreement, to be delivered to the
Trustee or Custodian. Any funds received by the Master Servicer or by the
Servicer in respect of any Mortgage Loan or which otherwise are collected by the
Master Servicer or by the Servicer as Liquidation Proceeds or Insurance Proceeds
in respect of any Mortgage Loan shall be held for the benefit of the Trustee and
the 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
the Servicer to retain its Servicing Fee and other amounts as provided in the
Servicing Agreement. The Master Servicer shall, and (to the extent provided in
the Servicing Agreement) shall cause the 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, and to 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
or Insurance Proceeds, shall be held by the Master Servicer for and on behalf of
the Trustee and the Certificateholders and shall be and remain the sole and
exclusive property of the Trustee; provided, however, that the Master Servicer
and the 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
the Servicer under this Agreement or the 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 Servicer under the Servicing Agreement to maintain or cause to
be maintained standard fire and casualty insurance and, where applicable, flood
insurance, all in accordance with the


                                      -51-

<PAGE>

provisions of the Servicing Agreement. It is understood and agreed that such
insurance shall be with insurers meeting the eligibility requirements set forth
in the 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 Sections 4.01 and 4.02, any amounts collected by the
Servicer or the Master 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
Servicing Agreement) shall be deposited into the Master Servicer Collection
Account, subject to withdrawal pursuant to Sections 4.02 and 4.03 in accordance
with the terms and conditions of the Servicing Agreement. Any cost incurred by
the Master Servicer or the 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 the
Servicer pursuant to Sections 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 Servicing Agreement) cause the
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 the 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 the Servicer (to the
extent such action is prohibited under the 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 such Master Servicer
or Servicer, would have been covered thereunder. The Master Servicer shall use
its best reasonable efforts to cause the Servicer (to the extent required under
the 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 Servicing Agreement, as applicable. The
Master Servicer shall not, and shall not permit the Servicer (to the extent
required under the 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 Servicing
Agreement, as applicable.


                                      -52-

<PAGE>

          (b) The Master Servicer agrees to present, or to cause the Servicer
(to the extent required under the 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 4.02, any
amounts collected by the Master Servicer or the Servicer under any Primary
Mortgage Insurance Policies shall be deposited in the Master Servicer Collection
Account, subject to withdrawal pursuant to Section 4.03.

     Section 3.12. Trustee to Retain Possession of Certain Insurance Policies
and Documents. The Trustee or the Custodian 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
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 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 the Servicer (to the extent required under the 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 terms and
conditions of the Servicing Agreement.

     Section 3.14. Compensation for the Master Servicer. The Master Servicer
will be entitled to all income and gain realized from any investment of funds in
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 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 Issuing Entity 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
Servicing Agreement, cause the Servicer to sell, any REO Property as
expeditiously as possible and in accordance with the provisions of this
Agreement and the Servicing Agreement, as applicable. Pursuant to its efforts to
sell such REO Property, the Master


                                       -53-

<PAGE>

Servicer shall cause the Servicer to protect and conserve, such REO Property in
the manner and to the extent required by the 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 Servicing
Agreement, cause the 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 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 Servicing Agreement, the Liquidation
Proceeds from the final disposition of the REO Property, net of any payment to
the Master Servicer and the 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 Statement as to Compliance.

     Not later than March 1 of each calendar year (other than the calendar year
during which the Closing Date occurs), the Servicer shall deliver (or otherwise
make available) and the Servicer shall cause any Servicing Function Participant
engaged by it to deliver to the Master Servicer, the Securities Administrator
and the Depositor, an Officer's Certificate in the form attached hereto as
Exhibit P stating, as to each signatory thereof, that (i) a review of the
activities of such signatory during the preceding calendar year, or portion
thereof, and of the performance of such signatory under the Servicing Agreement
or such other applicable agreement in the case of a Servicing Function
Participant has been made under such officer's supervision, and (ii) to the best
of such officer's knowledge, based on such review, such signatory has fulfilled
all its obligations under this Agreement, the Servicing Agreement or such other
applicable agreement in all material respects throughout such year or a portion
thereof, or, if there has been a failure to fulfill any such obligation in any
material respect, specifying each such failure known to such officer and the
nature and status thereof.

     The Master Servicer and the Securities Administrator shall deliver (or
otherwise make available) (and the Master Servicer and Securities Administrator
shall cause any Servicing Function Participant engaged by it to deliver) to the
Depositor and the Securities Administrator on or before March 1 (with a
ten-calendar day cure period) of each year, commencing in March 2007, an
Officer's Certificate stating, as to the signer thereof, that (A) a review of
such party's activities during the preceding calendar year or portion thereof
and of such party's performance under this Agreement, or such other applicable
agreement in the case of a Servicing Function

Participant, has been made under such officer's supervision and (B) to the best
of such officer's knowledge, based on such review, such party has fulfilled all
its obligations under this Agreement, or such other applicable agreement in the
case of a Servicing Function Participant, in all material respects throughout
such year or portion thereof, or, if there has been a failure to fulfill any
such obligation in any material respect, specifying each such failure known to
such officer and the nature and status thereof.

     The Master Servicer shall include all annual statements of compliance
received by it from the Servicer with its own annual statement of compliance to
be submitted to the Securities Administrator pursuant to this Section. For the
avoidance of doubt, the Master Servicer and the Securities Administrator may
satisfy the requirements of this Section 3.16 and Section 3.16 of the Stack II
Agreement by each delivering a single annual statement of compliance containing
all of the information required pursuant to this Section 3.16 and Section 3.16
of the Stack II Agreement.

     In the event the Master Servicer, the Securities Administrator or any
Servicing Function Participant engaged by any such party is terminated, assigns
its rights and obligations under or resigns pursuant to the terms of this
Agreement, or such other applicable agreement in the case of a Servicing
Function Participant, as the case may be, such party shall provide, an annual
statement of compliance pursuant to this Section 3.16 or to such applicable
agreement, as the case may be, notwithstanding any such termination, assignment
or resignation.

     Section 3.17. Reports on Assessment of Compliance and Attestation.

          (a) Not later than March 1 of each calendar year (other than the
calendar year during which the Closing Date occurs) the Servicer at its own
expense, shall furnish, and shall cause any Servicing Function Participant
engaged by it to furnish (unless in the case of a Subcontractor, the Servicer
has notified the Depositor and the Master Servicer in writing that such
compliance statement is not required for the Subcontractor) to the Master
Servicer, the Securities Administrator and the Depositor an officer's assessment
of its compliance with the Relevant Servicing Criteria during the preceding
calendar year as required by Rules 13a-18 and 15d-18 of the Exchange Act and
Item 1122 of Regulation AB (the "Assessment of Compliance"), which assessment

used the Relevant Servicing Criteria to assess compliance with the Relevant
Servicing Criteria, (C) such party's assessment of compliance with the Relevant
Servicing Criteria as of and for the fiscal year covered by the Form 10-K
required to be filed pursuant to Section 3.18, including, if there has been any
material instance of noncompliance with the Relevant Servicing Criteria, a
discussion of each such failure and the nature and status thereof, which
assessment shall be based on the activities it performs with respect to
asset-backed securities transactions taken as a whole involving such party that
are backed by the same asset type as the Mortgage Loans, and (D) a statement
that a registered public accounting firm has issued an attestation report on
such party's assessment of compliance with the Relevant Servicing Criteria as of

Custodian each at its own expense, shall furnish or otherwise make available,
and each such party shall cause any Servicing Function Participant engaged by it
to furnish, each at its own expense, to the Securities


                                      -55-

<PAGE>

Administrator and the Depositor, a report on an assessment of compliance with
the Relevant Servicing Criteria that contains (A) a statement by such party of
its responsibility for assessing compliance with the Relevant Servicing
Criteria, (B) a statement that such party used the Relevant Servicing Criteria
to assess compliance with the Relevant Servicing Criteria, (C) such party's

noncompliance with the Relevant Servicing Criteria, a discussion of each such
failure and the nature and status thereof, and (D) a statement that a registered
public accounting firm has issued an attestation report on such party's
assessment of compliance with the Relevant Servicing Criteria as of and for such
period.

     No later than the end of each fiscal year for the Issuing Entity for which

forward to the Securities Administrator and the Depositor the name of each
Servicing Function Participant engaged by it and what Relevant Servicing
Criteria will be addressed in the report on assessment of compliance prepared by
such Servicing Function Participant (provided, however, that the Master Servicer
need not provide such information to the Securities Administrator so long as the
Master Servicer and the Securities Administrator are the same Person). When the
Master Servicer, and the Securities Administrator (or any Servicing Function
Participant engaged by them) submit their assessments to the Securities
Administrator, such parties will also at such time include the assessment and
attestation pursuant to this Section 3.17 of each Servicing Function Participant

Agreement in respect of the Servicer and notify the Depositor of any exceptions.

     The Master Servicer shall include all annual reports on assessment of

     In the event the Master Servicer, the Securities Administrator or any
Servicing Function Participant engaged by any such party is terminated, assigns
its rights and obligations under or resigns pursuant to the terms of this
Agreement, or any other applicable agreement, as the case may be, such party
shall provide, an assessment of compliance pursuant to this Section 3.17,
coupled with an attestation as required in this Section 3.17, or such applicable
agreement notwithstanding any such termination, assignment or resignation.

          (b) Not later than March 1 of each calendar year (other than the
calendar year during which the Closing Date occurs) the Servicer at its own
expense, shall cause, and shall cause any Servicing Function Participant engaged
by it to cause (unless in the case of a Subcontractor, the Servicer has notified
the Depositor and the Master Servicer in writing that such report is not
required for the Subcontractor) a nationally or regionally recognized firm of
independent registered public accountants (who may also render other services to
the Servicer, the Master Servicer or any affiliate thereof) which is a member of
the American Institute of Certified Public Accountants to furnish a report (the
"Accountant's Attestation") to the Master Servicer, the Securities Administrator
and the Depositor to the effect that (i) it has obtained a representation
regarding certain matters from the management of such party, which includes an
assertion that such party has complied with the Relevant Servicing Criteria, and
(ii) on the basis of an examination conducted by such firm in accordance with
standards for attestation engagements issued or adopted by the Public Company
Accounting Oversight Board, it is expressing an opinion as to whether such
party's compliance with the Relevant Servicing Criteria was fairly stated in all
material respects, or it cannot express an overall opinion regarding such
party's assessment of compliance with the Relevant Servicing Criteria. In the
event that an overall opinion cannot be expressed, such registered public
accounting firm shall state in such report why it was unable to express such an
opinion. Such report must be available for general use and not contain
restricted use language. Such Accountant's Attestation shall be in accordance
with Rules 1-02(a)(3) and 2-02(g) of Regulation S-X under the Securities Act and
the Exchange Act.

     By March 1 (with a ten-calendar day cure period) of each year, commencing
in March 2007, the Master Servicer, the Securities Administrator and the
Custodian, each at its own expense, shall cause, and each such party shall cause
any Servicing Function Participant engaged by it to cause, each at its own
expense, a registered public accounting firm (which may also render other
services to the Master Servicer, the Trustee, the Securities Administrator, or
such other Servicing Function Participants, as the case may be) and that is a
member of the American Institute of Certified Public Accountants to furnish an
attestation report to the Securities Administrator and the Depositor, to the
effect that (i) it has obtained a representation regarding certain matters from
the management of such party, which includes an assertion that such party has
complied with the Relevant Servicing Criteria, and (ii) on the basis of an
examination conducted by such firm in accordance with standards for attestation
engagements issued or adopted by the Public Company Accounting Oversight Board,
it is expressing an opinion as to whether such party's compliance with the
Relevant Servicing Criteria was fairly stated in all material respects, or it
cannot express an overall opinion regarding such party's assessment of
compliance with the Relevant Servicing Criteria. In the event that an overall
opinion cannot be expressed, such registered public accounting firm shall state

available for general use and not contain restricted use language.

          (c) Promptly after receipt of each assessment of compliance and
attestation report, the Securities Administrator shall confirm that each
assessment submitted pursuant to Section 3.17(a) is coupled with an attestation
meeting the requirements of Section 3.17(b) and notify the Depositor of any
exceptions.

     The Master Servicer shall include each such attestation furnished to it by
the Servicer with its own attestation to be submitted to the Securities
Administrator pursuant to this Section. For the avoidance of doubt, the Master
Servicer and the Securities Administrator may satisfy the requirements of this
Section 3.17 and Section 3.17 of the Stack II Agreement relating to attestations
by each delivering a single attestation containing all of the information
required pursuant to this Section 3.17 and Section 3.17 of the Stack II
Agreement.

     In the event the Master Servicer, the Securities Administrator, the
Custodian, the Servicer or any Servicing Function Participant engaged by any
such party, is terminated, assigns its rights and duties under, or resigns
pursuant to the terms of, this Agreement, or any applicable Custodial Agreement,
Servicing Agreement or sub-servicing agreement, as the case may be, such party
shall cause a registered public accounting firm to provide an attestation
pursuant to this Section 3.17, or such other applicable agreement,
notwithstanding any such termination, assignment or resignation.

     Section 3.18. Periodic Filings.

          (a) Within four (4) Business Days after the occurrence of an event
requiring disclosure on Form 8-K (each such event, a "Reportable Event"), and if
requested by the Depositor, the Securities Administrator shall prepare and file
on behalf of the Issuing Entity a Form 8-K, as required by the Exchange Act,
provided that the Depositor shall file the initial Form 8-K in connection with
the issuance of the Certificates. Any disclosure or information related to a
Reportable Event or that is otherwise required to be included on Form 8-K (other
than the initial Form 8-K) ("Form 8-K Disclosure Information") shall be reported
by the parties set forth on Exhibit Q-3 to the Depositor and the Securities
Administrator and directed and approved by the Depositor, and the Securities
Administrator will have no duty or liability for any failure hereunder to
determine or prepare any Form 8-K Disclosure Information or any Form 8-K except
as set forth in the next paragraph.

          (b) For so long as the Issuing Entity is subject to the reporting
requirements of the Exchange Act, following the occurrence of a Reportable Event
(A) each party listed on Exhibit Q-3 hereto shall use commercially reasonable
best efforts to provide immediate notice to the Master Servicer, the Securities
Administrator and the Depositor, by fax and by phone or by e-mail and by phone,
(B) each such party shall be required to provide to the Securities Administrator
and the Depositor, to the extent known, in EDGAR-compatible format or in such
other format as agreed upon by the Securities Administrator and such party, the
form and substance of any Form 8-K Disclosure Information if applicable,
together with the form set forth on Exhibit O (the "Additional Disclosure
Notification") by the close of business New York City time on the 2nd Business
Day following the occurrence of such Reportable Event and (C) the Depositor,
shall approve, as to form and substance, or disapprove, as the case may be, the
inclusion of the Form 8-K Disclosure Information on Form 8-K. The Securities
Administrator has no duty under this Agreement to monitor or enforce the
performance by the parties listed on Exhibit Q-3 of their duties under this
paragraph or proactively solicit or procure from such parties any Form 8-K
Disclosure Information. The Depositor will be responsible for any reasonable
fees and expenses assessed or incurred by the Securities Administrator in
connection with including any Form 8-K Disclosure Information on Form 8-K
pursuant to this paragraph.


                                      -58-

<PAGE>

           (c) After preparing the Form 8-K, the Securities Administrator shall,
upon request, forward electronically a copy of the Form 8-K to the Depositor.
Promptly, but no later than the close of business on the third Business Day
after the Reportable Event, the Depositor shall notify the Securities
Administrator in writing (which may be furnished electronically) of any changes
to or approval of such Form 8-K. In the absence of receipt of any written
changes or approval, or if the Depositor does not request a copy of a Form 8-K,
the Securities Administrator shall be entitled to assume that such Form 8-K is
in final form and the Securities Administrator may proceed with the process for
execution and filing of the Form 8-K. A duly authorized representative of the
Master Servicer shall sign each Form 8-K. If a Form 8-K cannot be filed on time
or if a previously filed Form 8-K needs to be amended, the Securities
Administrator will follow the procedures set forth in Section 3.18(n).

          (d) Promptly (but no later than one Business Day) after filing with
the Commission, the Securities Administrator will make available on its internet
website a final executed copy of each Form 8-K prepared and filed by the
Securities Administrator. The parties to this Agreement acknowledge that the
performance by the Master Servicer and the Securities Administrator of its
duties under this Section 3.18 related to the timely preparation, execution and
filing of Form 8-K is contingent upon the other parties hereto strictly
observing all applicable deadlines in the performance of their duties under this
Section 3.18. The Depositor acknowledges that the performance by the Master
Servicer and the Securities Administrator of its duties under this Section 3.18
related to the timely preparation, execution and filing of Form 8-K is also
contingent upon the Servicer, the Custodian and any Servicing Function
Participant strictly observing deadlines no later than those set forth in this
paragraph that are applicable to the parties to this Agreement in the delivery
to the Securities Administrator of any necessary Form 8-K Disclosure Information
pursuant to the Servicing Agreement, the Custodial Agreement or any other
applicable agreement. Neither the Master Servicer nor the Securities
Administrator shall have any liability for any loss, expense, damage or claim
arising out of or with respect to any failure to properly prepare, execute
and/or timely file such Form 8-K, where such failure results from the Securities
Administrator's inability or failure to obtain or receive, on a timely basis,
any information from any other party hereto or the Servicer, Custodian or
Servicing Function Participant needed to prepare, arrange for execution or file
such Form 8-K.

          (e) Within fifteen (15) days after each Distribution Date (subject to
permitted extensions under the Exchange Act), the Securities Administrator
shall, on behalf of the Issuing Entity and in accordance with industry
standards, prepare and file with the Commission via the Electronic Data
Gathering and Retrieval System (EDGAR), a Form 10-D with a copy of the Monthly
Statement for such Distribution Date as an exhibit thereto. Any disclosure in
addition to the Monthly Statement that is required to be included on Form 10-D
("Additional Form 10-D Disclosure") shall be reported by the parties set forth
on Exhibit Q-1 to the Depositor and the Securities Administrator and directed
and approved by the Depositor pursuant to the following paragraph, and the
Securities Administrator will have no duty or liability for any failure
hereunder to determine or prepare any Additional Form 10-D Disclosure except as
set forth in the next paragraph.

          (f) As set forth in Exhibit Q-1 hereto, for so long as the Issuing
Entity is subject to the reporting requirements of the Exchange Act, within five
(5) calendar days after the related Distribution Date (i) each party listed on
Exhibit Q-1 hereto shall be required to provide


                                      -59-

<PAGE>

to the Depositor and the Securities Administrator, to the extent known, in
EDGAR-compatible format or in such other format as agreed upon by the Securities
Administrator and such party, the form and substance of any Additional Form 10-D
Disclosure if applicable together with an Additional Disclosure Notification,
and (ii) the Depositor will approve, as to form and substance, or disapprove, as
the case may be, the inclusion of the Additional Form 10-D Disclosure on Form
10-D. The Securities Administrator has no duty under this Agreement to monitor
or enforce the performance by the parties listed on Exhibit Q-1 of their duties
under this paragraph or proactively solicit or procure from such parties any
Additional Form 10-D Disclosure Information. The Depositor will be responsible
for any reasonable fees and expenses incurred by the Securities Administrator in
connection with including any Additional Form 10-D Disclosure on Form 10-D
pursuant to this paragraph.

          (g) After preparing the Form 10-D, the Securities Administrator shall,
upon request, forward electronically a copy of the Form 10-D to the Depositor
(provided that such Form 10-D includes any Additional Form 10-D Disclosure).
Within two Business Days after receipt of such copy, but no later than the 12th
calendar day after the Distribution Date, the Depositor shall notify the
Securities Administrator in writing (which may be furnished electronically) of
any changes to or approval of such Form 10-D. In the absence of receipt of any
written changes or approval, or if the Depositor does not request a copy of a
Form 10-D, the Securities Administrator shall be entitled to assume that such
Form 10-D is in final form and the Securities Administrator may proceed with the
process for execution and filing of the Form 10-D. A duly authorized
representative of the Master Servicer shall sign each Form 10-D. If a Form 10-D
cannot be filed on time or if a previously filed Form 10-D needs to be amended,
the Securities Administrator will follow the procedures set forth in Section
3.18(n). Promptly (but not later than one Business Day) after filing with the
Commission, the Securities Administrator will make available on its internet
website a final executed copy of each Form 10-D prepared and filed by the
Securities Administrator. Form 10-D requires the registrant to indicate (by
checking "yes" or "no") that it "(1) has filed all reports required to be filed
by Section 13 or 15(d) of the Exchange Act during the preceding 12 months (or
for such shorter period that the registrant was required to file such reports),
and (2) has been subject to such filing requirements for the past 90 days." The
Depositor hereby represents to the Securities Administrator that the Depositor
has filed all such required reports during the preceding 12 months and that it
has been subject to such filing requirement for the past 90 days. The Depositor
shall notify the Securities Administrator in writing, no later than the fifth
calendar day after the related Distribution Date with respect to the filing of a
report on Form 10-D, if the answer to the questions should be "no." The
Securities Administrator shall be entitled to rely on such representations in
preparing, executing and/or filing any such Form 10-D. The parties to this
Agreement acknowledge that the performance by the Master Servicer and the
Securities Administrator of its respective duties under this Section 3.18
related to the timely preparation, execution and filing of Form 10-D is
contingent upon the other parties hereto strictly observing all applicable
deadlines in the performance of their duties under this Section 3.18. The
Depositor acknowledges that the performance by the Master Servicer and the
Securities Administrator of its duties under this Section 3.18 related to the
timely preparation, execution and filing of Form 10-D is also contingent upon
the Servicer, the Custodian and any Servicing Function Participant strictly
observing deadlines no later than those set forth in this paragraph that are
applicable to the parties to this Agreement in the delivery to the Securities
Administrator of any necessary Additional Form 10-D Disclosure pursuant to the
Servicing Agreement, the Custodial Agreement or any other applicable agreement.
Neither the


                                      -60-

<PAGE>

Master Servicer nor the Securities Administrator will have any liability for any
loss, expense, damage or claim arising out of or with respect to any failure to
properly prepare, execute and/or timely file such Form 10-D resulting from the
Securities Administrator's inability or failure to obtain or receive any
information needed to prepare, arrange for execution or file such Form 10-D on a
timely basis.

          (h) On or prior to the 90th calendar day after the end of the fiscal
year for the Issuing Entity or such earlier date as may be required by the
Exchange Act (the "10-K Filing Deadline") (it being understood that the fiscal
year for the Issuing Entity ends on December 31st of each year) commencing in
March 2007, the Securities Administrator shall, on behalf of the Issuing Entity
and in accordance with industry standards, prepare and file with the Commission
via EDGAR a Form 10-K with respect to the Issuing Entity. Such Form 10-K shall
include the following items, in each case, as applicable, to the extent they
have been delivered to the Securities Administrator within the applicable time
frames set forth in this Agreement, the Servicing Agreement and Custodial
Agreement: (i) an annual compliance statement for the Master Servicer, the
Servicer, the Securities Administrator and any Servicing Function Participant
engaged by any such party (together with the Custodian, each a "Reporting
Servicer"), as described in Section 3.16 of this Agreement, the Servicing
Agreement and the Custodial Agreement; provided, however, that the Securities
Administrator, at its discretion, may omit from the Form 10-K any annual
compliance statement that is not required to be filed with such Form 10-K
pursuant to Regulation AB; (ii)(A) the annual reports on assessment of
compliance with Servicing Criteria for each Reporting Servicer (unless the
Depositor has determined that such compliance statement is not required by
Regulation AB), as described in Section 3.17 of this Agreement, the Servicing
Agreement and the Custodial Agreement, and (B) if any Reporting Servicer's
report on assessment of compliance with Servicing Criteria described in Section
3.17 identifies any material instance of noncompliance, disclosure identifying
such instance of noncompliance, or if any Reporting Servicer's report on
assessment of compliance with Servicing Criteria described in Section 3.17 of
this Agreement is not included as an exhibit to such Form 10-K, disclosure that
such report is not included and an explanation why such report is not included;
provided, however, that the Securities Administrator, at its discretion, may
omit from the Form 10-K any assessment of compliance or attestation report
described in clause (iii) below that is not required to be filed with such Form
10-K pursuant to Regulation AB; (iii)(A) the registered public accounting firm
attestation report for each Reporting Servicer, as described in Section 3.17 of
this Agreement, the Servicing Agreement and the Custodial Agreement, and (B) if
any registered public accounting firm attestation report described under Section
3.17 of this Agreement identifies any material instance of noncompliance,
disclosure identifying such instance of noncompliance, or if any such registered
public accounting firm attestation report is not included as an exhibit to such
Form 10-K, disclosure that such report is not included and an explanation why
such report is not included, and (iv) a Sarbanes-Oxley Certification in the form
attached hereto as Exhibit L, executed by the senior officer in charge of
securitizations of the Master Servicer. Any disclosure or information in
addition to (i) through (iv) above that is required to be included on Form 10-K
("Additional Form 10-K Disclosure") shall be reported by the parties as set
forth in Exhibit Q-2 to the Depositor and the Securities Administrator and
directed and approved by the Depositor pursuant to the following paragraph and
the Securities Administrator will have no duty or liability for any failure
hereunder to determine or prepare any Additional Form 10-K Disclosure except or
set forth in the next paragraph.


                                      -61-

<PAGE>

          (i) As set forth in Exhibit Q-2 hereto, no later than March 1 (with a
ten calendar day cure period) of each year that the Issuing Entity is subject to
the Exchange Act reporting requirements, commencing in March 2007, (i) the
parties listed on Exhibit Q-2 hereto shall be required to provide to the
Depositor and the Securities Administrator, to the extent known, in
EDGAR-compatible format or in such other format as agreed upon by the Securities
Administrator and such party, the form and substance of any Additional Form 10-K
Disclosure, if applicable together with an Additional Disclosure Notification,
and (ii) the Depositor will approve, as to form and substance, or disapprove, as
the case may be, the inclusion of the Additional Form 10-K Disclosure and shall
forward such Additional Form 10-K Disclosure. The Securities Administrator has
no duty under this Agreement to monitor or enforce the performance by the
parties listed on Exhibit Q-2 of their duties under this paragraph or
proactively solicit or procure from such parties any Additional Form 10-K
Disclosure Information. The Depositor will be responsible for any reasonable
fees and expenses incurred by the Securities Administrator in connection with
including any Additional Form 10-K Disclosure on Form 10-K pursuant to this
paragraph.

          (j) After preparing the Form 10-K, the Securities Administrator shall,
upon request, forward electronically a copy of the Form 10-K to the Depositor.
Within three Business Days after receipt of such copy, but no later than March
25th, the Depositor shall notify the Securities Administrator in writing (which
may be furnished electronically) of any changes to or approval of such Form
10-K. In the absence of receipt of any written changes or approval, or if the
Depositor does not request a copy of a Form 10-K, the Securities Administrator
shall be entitled to assume that such Form 10-K is in final form and the
Securities Administrator may proceed with the process for execution and filing
of the Form 10-K. A senior officer of the Master Servicer in charge of the
master servicing function shall sign the Form 10-K. If a Form 10-K cannot be
filed on time or if a previously filed Form 10-K needs to be amended, the
Securities Administrator will follow the procedures set forth in Section
3.18(n). Promptly (but no later than one Business Day) after filing with the
Commission, the Securities Administrator will make available on its internet
website a final executed copy of each Form 10-K prepared and filed by the
Securities Administrator. Form 10-K requires the registrant to indicate (by
checking "yes" or "no") that it "(1) has filed all reports required to be filed
by Section 13 or 15(d) of the Exchange Act during the preceding 12 months (or
for such shorter period that the registrant was required to file such reports),
and (2) has been subject to such filing requirements for the past 90 days." The
Depositor hereby represents to the Securities Administrator that the Depositor
has filed all such required reports during the preceding 12 months and that it
has been subject to such filing requirement for the past 90 days. The Depositor
shall notify the Securities Administrator in writing, no later than the 15th
calendar day of March in any year in which the Trust is subject to the reporting
requirements of the Exchange Act, if the answer to the questions should be "no."
The Securities Administrator shall be entitled to rely on such representations
in preparing, executing and/or filing any such Form 10-D. The parties to this
Agreement acknowledge that the performance by the Master Servicer and the
Securities Administrator of its duties under this Section 3.18 related to the
timely preparation, execution and filing of Form 10-K is contingent upon such
parties (and any Servicing Function Participant) strictly observing all
applicable deadlines in the performance of their duties under this Section 3.18,
Section 3.16 and Section 3.17. The Depositor acknowledges that the performance
by the Master Servicer and the Securities Administrator of its duties under this
Section 3.18 related to the timely preparation, execution and filing of Form
10-K is also contingent upon the Servicer, the Custodian and any


                                      -62-

<PAGE>

Servicing Function Participant strictly observing deadlines no later than those
set forth in this paragraph that are applicable to the parties to this Agreement
in the delivery to the Securities Administrator of any necessary Additional Form
10-K Disclosure, any annual statement of compliance and any assessment of
compliance and attestation pursuant to the Servicing Agreement, the Custodial
Agreement or any other applicable agreement. Neither the Master Servicer nor the
Securities Administrator shall have any liability for any loss, expense, damage
or claim arising out of or with respect to any failure to properly prepare,
execute and/or timely file such Form 10-K resulting from the Securities
Administrator's inability or failure to obtain or receive any information from
any other party hereto or the Servicer, Custodian or Servicing Function
Participant needed to prepare, execute or file such Form 10-K.

          (k) Each Form 10-K shall include a Sarbanes-Oxley Certification, which
shall be in the form attached hereto as Exhibit L. Each Servicer shall sign and
provide, and each of the Servicer, the Master Servicer and the Securities
Administrator shall cause any Servicing Function Participant engaged by it to
sign and provide, to the person who signs the Sarbanes-Oxley Certification (the
"Certifying Person") by March 1 (with a ten day cure period) of each year in
which the Issuing Entity is subject to the reporting requirements of the
Exchange Act and otherwise within a reasonable period of time upon request, a
certification (a "Back-Up Certification") (in the form attached hereto as
Exhibit M) upon which the Certifying Person, the entity for which the Certifying
Person acts as an officer and such entity's officers, directors and affiliates
(collectively, with the Certifying Person, the "Certification Parties") can
reasonably rely. The senior officer of the Master Servicer in charge of the
master servicing function shall serve as the Certifying Person on behalf of the
Issuing Entity. Such officer of the Certifying Person can be contacted by e-mail
at cts.sec.notifications@wellsfargo.com or by facsimile at 410-715-2380. In the
event any such party or Servicing Function Participant engaged by any such party
is terminated or resigns pursuant to the terms of this Agreement, or any other
applicable agreement, as the case may be, such party shall provide a Back-Up
Certification to the Master Servicer pursuant to this Section 3.18 with respect
to the period of time it was subject to this Agreement or any other applicable
agreement, as the case may be. Notwithstanding the foregoing, (i) the Master
Servicer and the Securities Administrator shall not be required to deliver a
Back-Up Certification to each other if both are the same Person and the Master
Servicer is the Certifying Person and (ii) the Master Servicer shall not be
obligated to sign the Sarbanes-Oxley Certification in the event that it does not
receive any Back-Up Certification required to be furnished to it pursuant to
this section or the Servicing Agreement or Custodial Agreement.

          (l) The Securities Administrator shall have no responsibility to file
any items with the Commission other than those specified in this section and the
Master Servicer shall execute any and all Form 10-Ds, 8-Ks and 10-Ks required
hereunder.

          (m) On or prior to January 30 of the first year in which the
Securities Administrator is able to do so under applicable law, the Securities
Administrator shall prepare and file a Form 15 Suspension Notification relating
to the automatic suspension of reporting in respect of the Issuing Entity under
the Exchange Act.

          (n) In the event that the Securities Administrator is unable to timely
file with the Commission all or any required portion of any Form 8-K, 10-D or
10-K required to be filed by this Agreement because required disclosure
information was either not delivered to it or delivered to it after the delivery
deadlines set forth in this Agreement or for any other reason, the


                                      -63-

<PAGE>

Securities Administrator will promptly notify electronically the Depositor of
such inability to make a timely filing with the Commission. In the case of Form
10-D and 10-K, the parties to this Agreement will cooperate to prepare and file
a Form 12b-25 and a 10-D/A and 10K/A, as applicable, pursuant to Rule 12b-25 of
the Exchange Act. In the case of Form 8-K, the Securities Administrator will,
upon receipt of all required Form 8-K Disclosure Information and upon the
approval and direction of the Depositor, include such disclosure information on
the next succeeding Form 10-D to be filed for the Issuing Entity. In the event
that any previously filed Form 8-K, 10-D or 10-K needs to be amended, in
connection with any Additional Form 10-D Disclosure (other than, in the case of
Form 10-D, for the purpose of restating any Monthly Statement), Additional Form
10-K Disclosure or Form 8-K Disclosure Information, the Securities Administrator
will electronically notify the Depositor and such other parties to the
transaction as are affected by such amendment, and such parties will cooperate
to prepare any necessary 8-K/A, 10-D/A or 10-K/A. Any Form 15, Form 12b-25 or
any amendment to Form 8-K, 10-D or 10-K shall be signed by duly authorized
representative or a senior officer in charge of master servicing, as applicable,
of the Master Servicer. The parties to this Agreement acknowledge that the
performance by the Master Servicer of its duties under this Section 3.18 related
to the timely preparation, execution and filing of Form 15, a Form 12b-25 or any
amendment to Form 8-K, 10-D or 10-K is contingent upon each such party
performing its duties under this Section. Neither the Master Servicer nor the
Securities Administrator shall have any liability for any loss, expense, damage
or claim arising out of or with respect to any failure to properly prepare,
execute and/or timely file any such Form 15, Form 12b-25 or any amendments to
Forms 8-K, 10-D or 10-K, where such failure results from the Securities
Administrator's inability or failure to receive, on a timely basis, any
information from any other party hereto or the Servicer, any Custodian or any
Servicing Function Participant needed to prepare, arrange for execution or file
such Form 15, Form 12b-25 or any amendments to Forms 8-K, 10-D or 10-K.

          (o) The Depositor and the Securities Administrator agree to use their
good faith efforts to cooperate in complying with the requirements of this
Section 3.18.

           (p) Each of the parties agrees to provide to the Securities
Administrator such additional information related to such party as the
Securities Administrator may reasonably request, including evidence of the
authorization of the person signing any certificate or statement, financial
information and reports, and such other information related to such party or its
performance hereunder.

          (q) Any notice or notification required to be delivered by the
Securities Administrator or Master Servicer to the Depositor pursuant to this
Section 3.18, may be delivered via facsimile to (212) 449-2700, via email to
paul_park@ml.com or telephonically by calling Paul Park at (212) 449-6380.

          (r) For the avoidance of doubt, any filings or deliverables required
under this Section 3.18 and Section 3.18 of the Stack II Agreement, may be
prepared, delivered and filed in a consolidated manner. The Master Servicer, the
Securities Administrator and the Depositor may satisfy the requirements of this
Section 3.18 and Section 3.18 of the Stack II Agreement with a single set of
filings and deliverables addressing the requirements of both this Section 3.18
and Section 3.18 of the Stack II Agreement.

     Section 3.19. Compliance with Regulation AB. Each of the parties hereto
acknowledges and agrees that the purpose of Sections 3.16, 3.17 and 3.18 is to
facilitate compliance by the Depositor with the provisions of Regulation AB, as
such may be amended or clarified from time to time. Therefore, each of the
parties agrees that the parties' obligations hereunder will be supplemented and
modified as necessary to be consistent with any such amendments, interpretive
advice or guidance, convention or consensus among active participants in the
asset-backed securities markets, advice of counsel, or otherwise in respect of
the requirements of Regulation AB and the parties shall comply with requests
made by the Depositor for delivery of additional or different information as the
Depositor may determine in good faith is necessary to comply with the provisions
of Regulation AB. Any such supplementation or modification shall be made in
accordance with Section 11.02 without the consent of the Certificateholders, and
may result in a change in the reports filed by the Securities Administrator on
behalf of the Issuing Entity under the Exchange Act.

                                   ARTICLE IV.
                                    ACCOUNTS

     Section 4.01. Protected Accounts.

           (a) The Master Servicer shall enforce the obligation of the Servicer
to establish and maintain a Protected Account in accordance with the Servicing
Agreement, with records to be kept with respect thereto on a Mortgage Loan by
Mortgage Loan basis, into which accounts shall be deposited within two Business
Days (or as of such other time specified in the Servicing Agreement) of receipt
all collections of principal and interest on any Mortgage Loan and with respect
to any REO Property received by the Servicer, including Principal Prepayments,
Insurance Proceeds, Liquidation Proceeds, Subsequent Recoveries and advances
made from the Servicer's own funds (less servicing compensation as permitted by
the Servicing Agreement in the case of the Servicer) and all other amounts to be
deposited in the Protected Account. The Servicer is hereby authorized to make
withdrawals from and deposits to the related Protected Account for purposes
required or permitted by this Agreement. To the extent provided in the Servicing
Agreement, the Protected Account shall be held in a Designated Depository
Institution and segregated on the books of such institution in the name of the
Trustee for the benefit of Certificateholders.

          (b) To the extent provided in the Servicing Agreement, amounts on
deposit in a Protected Account may be invested in Permitted Investments in the
name of the Trustee for the benefit of Certificateholders and, except as
provided in the preceding paragraph, not commingled with any other funds, such
Permitted Investments to mature, or to 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 Servicer under the Servicing
Agreement, and the risk of loss of moneys required to be distributed to the
Certificateholders resulting from such investments shall be borne by and be the
risk of the Servicer, as set forth in the Servicing Agreement. The Servicer (to
the extent provided in the Servicing Agreement) shall deposit the amount of any
such loss in the Protected 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.

this Article IV, on or before the Servicer Remittance Date, the Servicer shall

immediately deposit or cause to be deposited in the Master Servicer Collection
Account amounts representing the following collections and payments (other than
with respect to principal of or interest on the Mortgage Loans due on or before
the Cut-off Date):

               (i) Monthly Payments on the Mortgage Loans received or any
related portion thereof advanced by the Servicer pursuant to the Servicing
Agreement which were due on or before the related Due Date, net of the amount
thereof comprising the Servicing Fees;

                (ii) Principal Prepayments in Full and any Liquidation Proceeds

Prepayment Period, with interest to the date of prepayment or liquidation, net
of the amount thereof comprising the Servicing Fees;

               (iii) Curtailments received by the Servicer for such Mortgage
Loans in the related Prepayment Period; and

               (iv) Any amount to be used as a Monthly Advance.

          (d) Withdrawals by the Master Servicer may be made from an Account
only to make remittances as provided in Section 4.01(c), 4.02 and 4.03; to
reimburse the Master Servicer or the Servicer for Monthly Advances which have
been recovered by subsequent collection 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 this Agreement in accordance with Section 10.01. As provided in
Sections 4.01(c) and 4.02(b) certain amounts otherwise due to the Servicer may
be retained by them as set forth in the Servicing Agreement 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 Certificateholders, the Master Servicer
Collection Account as a segregated trust account or accounts. The Master
Servicer Collection Account may be a sub-account of the Distribution 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:

               (i) Any amounts withdrawn from a Protected Account or other
permitted account;

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

               (iii) Any Insurance Proceeds, Liquidation Proceeds or Subsequent
Recoveries received by or on behalf of the Master Servicer or which were not

               (iv) The repurchase price with respect to any Mortgage Loans
repurchased and all proceeds of any Mortgage Loans or property acquired in
connection with the optional termination of the trust;

               (v) Any amounts required to be deposited with respect to losses
on investments of deposits in an Account; and

               (vi) Any other amounts received by or on behalf of the Master
Servicer and required to be deposited in the Master Servicer Collection Account
pursuant to this Agreement.

          (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
this Agreement. The requirements for crediting the Master Servicer Collection
Account or the Distribution Account shall be exclusive, it being understood and
agreed that, without limiting the generality of the foregoing, payments in the
nature of (i) prepayment or late payment charges or assumption, tax service,
statement account or payoff, substitution, satisfaction, release and other like
fees and charges and (ii) the items enumerated in Subsections 4.05(a)(i), (ii),
(iii), (iv), (vi), (vii), (viii), (ix), (xi) and (xii) with respect to the
Securities Administrator, need not be credited by the Master Servicer or the
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 Securities Administrator, 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 from the Distribution Account, any
provision herein to the contrary notwithstanding.

          (c) The amount at any time credited to the Master Servicer Collection
Account shall be invested, in the name of the Trustee, or its nominee, for the
benefit of the Certificateholders, 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 Collection 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 Certificateholders 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.

          (d) For the avoidance of doubt, it is agreed that the Master Servicer
shall establish and maintain in the name of the Trustee, for the benefit of the
holders of the Stack II Certificates, a separate segregated trust account or
accounts pursuant to Section 4.02 of the Stack II Agreement.

     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 the
Master Servicer, the Trustee 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 the 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 recoverable by the Trustee,
the Master Servicer or the Securities Administrator pursuant to this Agreement,
including but not limited to Sections 2.01(b), 3.03, 7.04 and 9.05 and (ii) any
amounts payable to the Master Servicer as set forth in Section 3.14.

          (c) In addition, on or before each Distribution Account Deposit Date,
the Master Servicer shall deposit in the Distribution Account (or remit to the
Securities Administrator for deposit therein) any Monthly Advances required to
be made by the Master Servicer with respect to the Mortgage Loans.

          (d) No later than 3:00 p.m. New York time on each Distribution Account
Deposit Date, the Master Servicer will transfer the Available Distribution
Amount on deposit in the Master Servicer Collection Account with respect to the
related Distribution Date to the Securities Administrator for deposit in the
Distribution Account.

     Section 4.04. Distribution Account.

          (a) The Securities Administrator shall establish and maintain in the
name of the Trustee, for the benefit of the Certificateholders, the Distribution
Account as a segregated trust account or accounts.

          (b) All amounts deposited to the Distribution Account shall be held by
the Securities Administrator in the name of the Trustee in trust for the benefit
of the 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 Securities Administrator and held by
the Securities Administrator 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 to the maximum extent permitted by applicable law from,
all claims, liens, and encumbrances of any creditors or depositors of the
Securities Administrator, the Trustee or the Master Servicer (whether made
directly, or indirectly through a liquidator or receiver of the Securities
Administrator, the Trustee 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) fully insured by the FDIC to the maximum
coverage provided thereby or (ii) invested in the name of the Trustee, in such
Permitted Investments selected by the Master Servicer or deposited in demand
deposits with such depository institutions as selected by the Master Servicer,
provided that time deposits of such


                                      -68-

<PAGE>

depository institutions would be a Permitted Investment. All Permitted
Investments shall mature or be subject to redemption or withdrawal on or before,
and shall be held until, the next succeeding Distribution Date if the obligor
for such Permitted Investment is the Master Servicer or, if such obligor is any
other Person, the Business Day preceding such Distribution Date. All investment
earnings on amounts on deposit in the Distribution Account or benefit from funds
uninvested therein from time to time shall be for the account of the Securities
Administrator. The Securities Administrator shall be permitted to withdraw or
receive distribution of any and all investment earnings from the Distribution
Account on each Distribution Date. If there is any loss on a Permitted
Investment or demand deposit, the Securities Administrator shall deposit such
amount in the Distribution Account. With respect to the Distribution Account and
the funds deposited therein, the Securities Administrator shall take such action
as may be necessary to ensure that the Certificateholders shall be entitled to
the priorities afforded to such a trust account (in addition to a claim against
the estate of the Trust) as provided by 12 U.S.C. Section 92a(e), and applicable
regulations pursuant thereto, if applicable, or any applicable comparable state
statute applicable to state chartered banking corporations.

          (d) For the avoidance of doubt, the Securities Administrator shall
establish and maintain in the name of the Trustee, for the benefit of the
holders of the Stack II Certificates, a separate segregated trust account or
accounts pursuant to Section 4.04 of the Stack II Agreement.

     Section 4.05. Permitted Withdrawals and Transfers from the Distribution
Account.

          (a) The Securities Administrator will, from time to time on demand of
the Master Servicer, make or cause to be made such withdrawals or transfers from
the Distribution Account as the Master Servicer has designated for such transfer
or withdrawal pursuant to the Servicing Agreement for the following purposes
(limited in the case of amounts due the Master Servicer to those not withdrawn
from the Master Servicer Collection Account in accordance with the terms of this
Agreement):

               (i) to reimburse the Master Servicer or the Servicer for any
Monthly Advance of its own funds or any advance of the Servicer's own funds, the
right of the Master Servicer or the Servicer to reimbursement pursuant to this

and Liquidation Proceeds) which represent late payments or recoveries of the
principal of or interest on such Mortgage Loan respecting which such Monthly
Advance or advance was made;

               (ii) to reimburse the Master Servicer or the Servicer from
Insurance Proceeds or Liquidation Proceeds relating to a particular Mortgage

the liquidation of such Mortgage Loan;

Liquidation Expenses incurred with respect to


                                      -69-

such Mortgage Loan; provided that the Master Servicer shall not be entitled to
reimbursement for Liquidation Expenses with respect to a Mortgage Loan to the
extent that (i) any amounts with respect to such Mortgage Loan were paid as
Excess Liquidation Proceeds pursuant to clause (xi) of this Subsection 4.05(a)
to the Master Servicer; and (ii) such Liquidation Expenses were not included in
the computation of such Excess Liquidation Proceeds;

               (iv) to pay the Master Servicer or the Servicer, as appropriate,
from Liquidation Proceeds or Insurance Proceeds received in connection with the
liquidation of any Mortgage Loan, the amount which it or the Servicer would have
been entitled to receive under subclause (ix) of this Subsection 4.05(a) as
servicing compensation on account of each defaulted scheduled payment on such
Mortgage Loan if paid in a timely manner by the related Mortgagor;

               (v) to pay the Master Servicer or the Servicer from the Purchase
Price for any Mortgage Loan, the amount which it or the Servicer would have been
entitled to receive under subclause (ix) of this Subsection 4.05(a) as servicing
compensation;

               (vi) to reimburse the Master Servicer or the Servicer for
advances of funds pursuant to Sections, and the right to reimbursement pursuant

which such advances were made;

               (vii) to reimburse the Master Servicer or the Servicer for any

liabilities incurred by and reimbursable to it pursuant to this Agreement,
including but not limited to Sections 3.03, 7.04(c) and (d);

               (x) to pay to the Master Servicer, as additional servicing
compensation, any Excess Liquidation Proceeds to the extent not retained by the

               (xi) to reimburse or pay the Servicer any such amounts as are due
thereto under the Servicing Agreement and have not been retained by or paid to

<PAGE>

          (b) The Master Servicer shall keep and maintain separate accounting,
on a Mortgage Loan by Mortgage Loan basis, for the purpose of accounting for any
reimbursement from the Distribution Account pursuant to subclauses (i) through
(vi), inclusive, and (viii) 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 Securities Administrator shall
distribute the Available Distribution Amount to the Holders of the Certificates
in accordance with Section 6.01.

                                   ARTICLE V.
                                   CERTIFICATES

     Section 5.01. The Certificates. The Certificates shall be executed by
manual or facsimile signature on behalf of the Securities Administrator by an
authorized officer. Certificates bearing the manual or facsimile signatures of
individuals who were, at the time when such signatures were affixed, authorized
to sign on behalf of the Securities Administrator shall bind the Issuing Entity,
notwithstanding that such individuals or any of them have ceased to be so
authorized prior to the authentication and delivery of such Certificates or did
not hold such offices at the date of such authentication and delivery. No
Certificate shall be entitled to any benefit under this Agreement, or be valid
for any purpose, unless there appears on such Certificate a certificate of
authentication substantially in the form set forth as attached hereto executed
by the Securities Administrator by manual signature, and such certificate of
authentication upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly authenticated and delivered
hereunder. All Certificates shall be dated the date of their authentication. On
the Closing Date, the Securities Administrator shall authenticate the
Certificates to be issued at the written direction of the Depositor, or any
Affiliate thereof.

     Section 5.02. Certificate Register; Registration of Transfer and Exchange
of Certificates.

          (a) The Securities Administrator shall maintain, or cause to be
maintained in accordance with the provisions of Section 5.09 hereof, a
Certificate Register for the Trust Fund in which, subject to the provisions of
subsections (b) and (c) below and to such reasonable regulations as it may
prescribe, the Securities Administrator shall provide for the registration of
Certificates and of Transfers and exchanges of Certificates as herein provided.
Upon surrender for registration of Transfer of any Certificate, the Securities
Administrator shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Certificates of the same Class and of
like aggregate Percentage Interest.

     At the option of a Certificateholder, Certificates may be exchanged for
other Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest upon surrender of the Certificates to be
exchanged at the office or agency of the Securities Administrator. Whenever any
Certificates are so surrendered for exchange, the Securities Administrator shall
execute, authenticate and deliver the Certificates that the Certificateholder
making the exchange is entitled to receive. Every Certificate presented or


                                      -71-

<PAGE>

surrendered for registration of Transfer or exchange shall be accompanied by a
written instrument of Transfer in form satisfactory to the Securities
Administrator duly executed by the holder thereof or his attorney duly
authorized in writing.

     No service charge to the Certificateholders shall be made for any
registration of Transfer or exchange of Certificates, but 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 may be required. All
Certificates surrendered for registration of Transfer or exchange shall be
canceled and subsequently destroyed by the Securities Administrator in
accordance with such Securities Administrator's customary procedures.

          (b) No Transfer of a Class B Certificate shall be made unless such
Transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under the Securities Act and such state securities
laws. In the event that a Transfer is to be made in reliance upon an exemption
from the Securities Act and such laws, in order to assure compliance with the
Securities Act and such laws, the Certificateholder desiring to effect such
Transfer and such Certificateholder's prospective transferee shall (except with
respect to the initial transfer of a Class B Certificate by Merrill Lynch & Co.)
each certify to each Securities Administrator in writing the facts surrounding
the Transfer in substantially the form set forth in Exhibit F-1 (the "Transferor
Representation Letter") and (i) deliver a letter in substantially the form of
either Exhibit F-2 (the "Investor Representation Letter") or Exhibit F-3 (the
"Rule 144A Letter") or (ii) there shall be delivered to the Securities
Administrator an Opinion of Counsel that such Transfer may be made pursuant to
an exemption from the Securities Act, which Opinion of Counsel shall not be an
expense of the Depositor or the Securities Administrator. The Depositor shall
provide to any Holder of a Class B Certificate and any prospective transferee
designated by any such Holder, information regarding the related Certificates
and the Mortgage Loans and such other information as shall be necessary to
satisfy the condition to eligibility set forth in Rule 144A(d)(4) for Transfer
of any such Certificate without registration thereof under the Securities Act
pursuant to the registration exemption provided by Rule 144A. The Securities
Administrator shall cooperate with the Depositor in providing the Rule 144A
information referenced in the preceding sentence, including providing to the
Depositor such information in the possession of the Securities Administrator
regarding the Certificates, the Mortgage Loans and other matters regarding the
Trust Fund as the Depositor shall reasonably request to meet its obligation
under the preceding sentence. Each Holder of a Class B Certificate desiring to
effect such Transfer shall, and does hereby agree to, indemnify the Depositor
and the Securities Administrator against any liability that may result if the
Transfer is not so exempt or is not made in accordance with such federal and
state laws.

     No transfer of an ERISA Restricted Certificate will be registered unless
the Securities Administrator has received (A) a representation to the effect
that such transferee is not an employee benefit plan subject to Title I of
ERISA, a plan subject to Section 4975 of the Code or a plan subject to any
state, local, federal, non-U.S. or other law substantively similar to the
foregoing provisions of ERISA or the Code ("Similar Law") (collectively, a
"Plan"), and is not directly or indirectly acquiring such Certificate for, on
behalf of, or with any assets of any such Plan, or (B) solely in the case of an
ERISA Restricted Certificate (I) if the Certificate has been the subject of an
ERISA-Qualifying Underwriting, a representation to the effect that such


                                      -72-

<PAGE>

transferee is an insurance company that is acquiring the Certificate with assets
contained in an "insurance company general account," as defined in Section V(e)
of Prohibited Transaction Class Exemption ("PTCE") 95-60, and the acquisition
and holding of the Certificate are covered and exempt under Sections I and III
of PTCE 95-60, or (II) solely in the case of a Definitive Certificate, an
Opinion of Counsel satisfactory to the Securities Administrator, and upon which
the Securities Administrator shall be entitled to rely, to the effect that the
acquisition and holding of such Certificate will not constitute or result in a
nonexempt prohibited transaction under Title I of ERISA or Section 4975 of the
Code, or a violation of Similar Law, and will not subject the Securities
Administrator, the Master Servicer, the Trustee or the Depositor to any
obligation in addition to those expressly undertaken in this Agreement, which
Opinion of Counsel shall not be an expense of the Securities Administrator, the
Master Servicer, the Trustee or the Depositor.

     Except in the case of a Definitive Certificate, the representations set
forth in the immediately preceding paragraph of this Subsection 5.02(b), other
than clause (B)(II) in the immediately preceding paragraph, shall be deemed to
have been made to the Securities Administrator by the transferee's acceptance of
an ERISA Restricted Certificate (or the acceptance by a Certificate Owner of the
beneficial interest in any Class of ERISA Restricted Certificates).

     Notwithstanding any other provision herein to the contrary, any purported
transfer of an ERISA Restricted Certificate to or on behalf of a Plan without
the delivery to the Securities Administrator of a representation or an Opinion
of Counsel satisfactory to the Securities Administrator as described above shall
be void and of no effect. The Securities Administrator shall not be under any
liability to any Person for any registration or transfer of any ERISA Restricted
Certificate that is in fact not permitted by this Section 5.02(b), nor shall the
Trustee or the Securities Administrator be under any liability for making any
payments due on such Certificate to the Holder thereof or taking any other
action with respect to such Holder under the provisions of this Agreement so
long as the transfer was registered by the Securities Administrator in
accordance with the foregoing requirements. The Trustee or the Securities
Administrator shall be entitled, but not obligated, to recover from any Holder
of any ERISA Restricted Certificate that was in fact a Plan and that held such
Certificate in violation of this Section 5.02(b) all payments made on such ERISA
Restricted Certificate at and after the time it commenced such holding. Any such
payments so recovered shall be paid and delivered to the last preceding Holder
of such Certificate that is not a Plan.

          (c) [Reserved]

          (d) [Reserved]

          (e) The preparation and delivery of all certificates, opinions and
other writings referred to above in this Section 5.02 shall not be an expense of
the Issuing Entity, the Depositor or the Securities Administrator.

     Section 5.03. Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any
mutilated Certificate is surrendered to the Securities Administrator or the
Securities Administrator receives evidence to its satisfaction of the
destruction, loss or theft of any Certificate and of the ownership thereof and
(b) there is delivered to the Securities Administrator such security or
indemnity as may be required by them to save each of them harmless, then, in the
absence of notice to the


                                      -73-

<PAGE>

Securities Administrator that such Certificate has been acquired by a bona fide
purchaser, the Securities Administrator shall execute, authenticate and deliver,
in exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate of like Class, tenor and Percentage Interest. In
connection with the issuance of any new Certificate under this Section 5.03, the
Securities Administrator may require the payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the fees and expenses of the Securities
Administrator) connected therewith. Any replacement 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. All Certificates
surrendered to the Securities Administrator under the terms of this Section 5.03
shall be canceled and destroyed by the Securities Administrator in accordance
with its standard procedures without liability on its part.

     Section 5.04. Persons Deemed Owners. The Securities Administrator and any
agent of the Securities Administrator may treat the Person in whose name any
Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions as provided in this Agreement and for all other purposes
whatsoever, and neither the Securities Administrator, nor any agent of the
Securities Administrator shall be affected by any notice to the contrary.

     Section 5.05. Access to List of Certificateholders' Names and Addresses. If
three or more Certificateholders (a) request such information in writing from
the Securities Administrator, (b) state that such Certificateholders desire to
communicate with other Certificateholders with respect to their rights under
this Agreement or under the Certificates, and (c) provide a copy of the
communication that such Certificateholders propose to transmit or if the
Depositor shall request such information in writing from the Securities
Administrator, then the Securities Administrator shall, within ten Business Days
after the receipt of such request, provide the Depositor or such
Certificateholders at such recipients' expense the most recent list of the
Certificateholders of the Trust Fund held by the Securities Administrator, if
any. The Depositor and every Certificateholder, by receiving and holding a
Certificate, agree that the Securities Administrator shall not be held
accountable by reason of the disclosure of any such information as to the list
of the Certificateholders hereunder, regardless of the source from which such
information was derived.

     Section 5.06. Book-Entry Certificates. The Regular Certificates, upon
original issuance, shall be issued in the form of one or more typewritten
Certificates representing the Book-Entry Certificates, to be delivered to the
Depository by or on behalf of the Depositor. The Book-Entry Certificates shall
initially be registered on the Certificate Register in the name of the
Depository or its nominee, and no Certificate Owner of a Book-Entry Certificate
will receive a definitive certificate representing such Certificate Owner's
interest in such Certificates, except as provided in Section 5.08. Unless and
until definitive, fully registered Certificates ("Definitive Certificates") have
been issued to the Certificate Owners of the Book-Entry Certificates pursuant to
Section 5.08:

          (a) the provisions of this Section shall be in full force and effect;

          (b) the Depositor and the Securities Administrator may deal with the
Depository and the Depository Participants for all purposes (including the
making of


                                      -74-

<PAGE>

distributions) as the authorized representative of the respective Certificate
Owners of the Book-Entry Certificates;

          (c) registration of the Book-Entry Certificates may not be transferred
by the Securities Administrator except to another Depository;

          (d) the rights of the respective Certificate Owners of the Book-Entry
Certificates shall be exercised only through the Depository and the Depository
Participants and shall be limited to those established by law and agreements
between the Owners of the Book-Entry Certificates and the Depository and/or the
Depository Participants. Pursuant to the Depository Agreement, unless and until
Definitive Certificates are issued pursuant to Section 5.08, the Depository will
make book-entry transfers among the Depository Participants and receive and
transmit distributions of principal and interest on the related Certificates to
such Depository Participants;

          (e) the Depository may collect its usual and customary fees, charges
and expenses from its Depository Participants;

          (f) the Securities Administrator may rely and shall be fully protected
in relying upon information furnished by the Depository with respect to its
Depository Participants; and

          (g) to the extent that the provisions of this Section conflict with
any other provisions of this Agreement, the provisions of this Section shall
control.

      For purposes of any provision of this Agreement requiring or permitting
actions with the consent of, or at the direction of, Certificateholders
evidencing a specified percentage of the aggregate unpaid principal amount of
any Class of Certificates, such direction or consent may be given by Certificate
Owners (acting through the Depository and the Depository Participants) owning
Book-Entry Certificates evidencing the requisite percentage of principal amount
of such Class of Certificates.

     Section 5.07. Notices to Depository. Whenever any notice or other
communication is required to be given to Certificateholders of the Class with
respect to which Book-Entry Certificates have been issued, unless and until
Definitive Certificates shall have been issued to the related Certificate
Owners, the Securities Administrator shall give all such notices and
communications to the Depository.

     Section 5.08. Definitive Certificates. If, after Book-Entry Certificates
have been issued with respect to any Certificates, (a) the Depository or the
Depositor advises the Securities Administrator that the Depository is no longer
willing, qualified or able to discharge properly its responsibilities under the
Depository Agreement with respect to such Certificates and the Securities
Administrator or the Depositor is unable to locate a qualified successor, (b)
the Depositor notifies the Securities Administrator and the Depository of its
intent to terminate the book-entry system through the Depository and, upon
receipt of notice of such intent from the Depository, the Certificate Owners of
the Book-Entry Certificates agree to initiate such termination or (c) after the
occurrence and continuation of an Event of Default, Certificate Owners of such
Book-Entry Certificates having not less than 51% of the Voting Rights


                                      -75-

<PAGE>

evidenced by any Class of Book-Entry Certificates advise the Securities
Administrator and the Depository in writing through the Depository Participants
that the continuation of a book-entry system with respect to Certificates of
such Class through the Depository (or its successor) is no longer in the best
interests of the Certificate Owners of such Class, then the Securities
Administrator shall notify all Certificate Owners of such Book-Entry
Certificates, through the Depository, of the occurrence of any such event and of
the availability of Definitive Certificates to Certificate Owners of such Class
requesting the same. The Depositor shall provide the Securities Administrator
with an adequate inventory of certificates to facilitate the issuance and
transfer of Definitive Certificates. Upon surrender to the Securities
Administrator of any such Certificates by the Depository, accompanied by
registration instructions from the Depository for registration, the Securities
Administrator shall authenticate and deliver such Definitive Certificates.
Neither the Depositor nor the Securities Administrator shall be liable for any
delay in delivery of such instructions and each may conclusively rely on, and
shall be protected in relying on, such instructions. Upon the issuance of such
Definitive Certificates, all references herein to obligations imposed upon or to
be performed by the Depository shall be deemed to be imposed upon and performed
by the Securities Administrator, to the extent applicable with respect to such
Definitive Certificates and the Securities Administrator shall recognize the
Holders of such Definitive Certificates as Certificateholders hereunder.

     Section 5.09. Maintenance of Office or Agency. The Securities Administrator
will maintain or cause to be maintained at its expense an office or offices or
agency or agencies where Certificates may be surrendered for registration of
transfer or exchange. The Securities Administrator initially designates its
offices at Sixth Street and Marquette Avenue, Minneapolis, Minnesota 55479,
Attention: Corporate Trust Services - Merrill Lynch Mortgage Investors Trust,
Series 2006-AF2 as offices for such purposes. The Securities Administrator will
give prompt written notice to the Certificateholders of any change in such
location of any such office or agency. For the avoidance of doubt, the
Securities Administrator may satisfy the requirements of both this Section 5.09

Principal Prepayment Period; and (ii) the respective portions of such Realized
Losses allocable to interest and to principal.

          (b) The principal portion of any Realized Losses shall be allocated as

<PAGE>
  Certificate Balance of the Class BF-2 Certificates has been reduced to zero;

Class BF-1 Certificates has been reduced to zero; fourth, to the Class MF-3

of the Class AF-3 Certificates has been reduced to zero; and then to the Class
AF-2 Certificates, until the Class Certificate Balance of such class has been
reduced to zero provided, however, that if a Realized Loss occurs with respect
to a Discount Mortgage Loan (a) the amount of such Realized Loss equal to the
product of (i) the amount of such Realized Loss and (ii) the PO Percentage with
respect to such Discount Mortgage Loan will be allocated to Class PO
Certificates and (b) the remainder of such Realized Loss will be allocated as
described above.

          (c) As used herein, an allocation of a Realized Loss on a "pro rata
basis" among two or more specified Classes of Certificates means an allocation
on a pro rata basis, among the various Classes so specified, to each such Class
of Certificates on the basis of their Class Certificate Balances prior to giving
effect to distributions to be made on such Distribution Date. All Realized
Losses and all other losses allocated to a Class of Certificates hereunder will
be allocated among the Certificates of such Class in proportion to the
Percentage Interests evidenced thereby.

          (d) In the event that a recovery is made with respect to any Realized
Loss, the amount of such recovery shall be treated as a Principal Prepayment and
deposited into the Master Servicer Collection Account and distributed on the
applicable Distribution Date.

     Section 6.03. Subordination. The rights of the Class B Certificateholders
to receive distributions in respect of the Class B Certificates on any
Distribution Date shall be subordinated to the rights of the Class A and Class M
Certificateholders to receive distributions in respect of the Class A and Class
M Certificates. The rights of the Class M Certificateholders to receive
distributions in respect of the Class M Certificates on any Distribution Date
shall be subordinated to the rights of the Class A Certificateholders to receive
distributions in respect of the Class A Certificates. The rights of the Class
BF-1 Certificateholders to receive distributions in respect of the Class BF-1
Certificates on any Distribution Date shall be subordinate to the rights of the

such Class A and Class M Certificates. Each Class of Class B Certificates (other
than the Class BF-1 Certificates) is subordinated to the Class A Certificates,
the Class M Certificates and each Class of Class B Certificates having a lower
numerical class designation than such Class of Class B Certificates. The rights
of the Class MF-1 Certificateholders to receive distributions in respect of the
Class MF-1 Certificates on any Distribution Date shall be subordinate to the
rights of the Class A Certificateholders to receive distributions in respect of
such Class A Certificates. Each Class of Class M Certificates (other than the
Class MF-1 Certificates) is subordinated to the Class A Certificates and each
Class of Class M Certificates having a lower numerical class designation than
such Class of Class M Certificates.

respect to such Mortgage Loan, the Master Servicer will deposit in the Master
Servicer Collection Account not later than the Distribution Account Deposit Date
immediately preceding the related Distribution Date an amount equal to such
deficiency, net of the Servicing Fee for such Mortgage Loan, except to the
extent the Master


                                      -83-

<PAGE>

Servicer determines any such Monthly Advance to be nonrecoverable from
Liquidation Proceeds, Insurance Proceeds or future payments on the Mortgage Loan
for which such Monthly Advance was made. If the Master Servicer has not
deposited the amount described above as of the related Distribution Account
Deposit Date, the Trustee will, subject to applicable law and its determination
of recoverability, deposit in the Master Servicer Collection Account not later
than the related Distribution Date, an amount equal to the remaining deficiency
as of the Distribution Account Deposit Date. Subject to the foregoing, the
Master Servicer shall continue to make such Monthly Advances through the date
that the Servicer is required to do so under its Servicing Agreement. If
applicable, on the Distribution Account Deposit Date, the Master Servicer shall
present an Officer's Certificate to the Securities Administrator (i) stating
that the Master Servicer elects not to make a Monthly Advance in a stated amount
and (ii) detailing the reason it deems the advance to be nonrecoverable.

     Section 6.07. Compensating Interest Payments. The Master Servicer shall
deposit in the Master Servicer Collection Account not later than each
Distribution Account Deposit Date an amount equal to the aggregate amounts
required to be paid by the Servicer under the Servicing Agreement with respect
to subclause (a) of the definition of Prepayment Interest Shortfall with respect
to the Mortgage Loans for the related Distribution Date, and not so paid by the
Servicer (such amount, the "Compensating Interest Payment"). The Master Servicer
shall not be entitled to any reimbursement of any Compensating Interest Payment;
provided, however, the aggregate compensating interest payments made by the
Master Servicer shall not exceed the Master Servicing Compensation.

     Section 6.08. Allocation of Certain Interest Shortfalls.

          (a) On any Distribution Date, the excess, if any, of (X) the aggregate
amounts required to be paid by the Servicer under the Servicing Agreement with
respect to subclause (a) of the definition of Prepayment Interest Shortfall with
respect to the Mortgage Loans for the related Distribution Date, and not so paid
by the Servicer over (Y) the Compensating Interest Payment actually paid into
the Master Servicer Collection Account pursuant to Section 6.06 for such
Distribution Date shall equal the "Compensating Interest Shortfall" with respect
to such Distribution Date. On any Distribution Date, the Compensating Interest
Shortfall shall be allocated pro rata among the outstanding Classes of Class A,
Class M and Class B Certificates based on the amount of interest to which each
such Class would otherwise be paid on such Distribution Date had there been no
such Compensating Interest Shortfall.

          (b) On any Distribution Date, the interest portion of any Realized
Losses ("Realized Loss Interest Shortfall") shall be allocated to the Class of
Subordinate Certificates then outstanding having the highest numerical class
designation or, if no Class of Subordinate Certificates is then outstanding, to
the Class A Certificates (other than the Class PO Certificates) pro rata among
the outstanding Classes of Class A Certificates (other than the Class PO
Certificates) based on the amount of interest to which each such Class would
otherwise be entitled on such Distribution Date had there been no such Realized
Loss Interest Shortfall.

          (c) Any interest shortfall resulting from the Relief Act or any
similar state legislation, as amended shall be allocated pro rata among the
outstanding Classes of Certificates based upon the amount of interest to which
each such Class would otherwise be paid on such Distribution Date.

undertake any such action which it may deem necessary or desirable with respect
to this Agreement and the rights and duties of the parties hereto and the
interests of the Certificateholders hereunder. In such event, the legal expenses
and costs of such action and any liability resulting therefrom shall be
expenses, costs and liabilities of the Issuing Entity, and the Master Servicer
shall be entitled to be reimbursed therefor out of the Master Servicer
Collection Account as provided by Section 4.03. Nothing in this Subsection
7.04(d) shall affect the Master Servicer's obligation to supervise, or to take
such actions as are necessary to ensure, the servicing and administration of the
Mortgage Loans pursuant to Section 3.01.

          (e) In taking or recommending any course of action pursuant to this
Agreement, unless specifically required to do so pursuant to this Agreement, the
Master Servicer shall not be required to investigate or make recommendations
concerning potential liabilities which the Issuing Entity might incur as a
result of such course of action by reason of the condition of the Mortgaged
Properties but shall give notice to the Trustee if it has notice of such
potential liabilities.

          (f) The Master Servicer shall not be liable for any acts or omissions
of the Servicer, except as otherwise expressly provided herein.

     Section 7.05. Master Servicer Not to Resign. Except as provided in Section
7.07, the Master Servicer shall not resign from the obligations and duties
hereby imposed on it except upon a determination that any such duties hereunder
are no longer permissible under applicable law and such impermissibility cannot
be cured. Any such determination permitting the resignation of the Master
Servicer shall be evidenced by an Opinion of Independent Counsel to such effect
delivered to the Trustee. No such resignation by the Master Servicer shall
become effective until MLML or the Trustee or a successor to the Master Servicer
reasonably satisfactory to the Trustee shall have assumed the responsibilities
and obligations of the Master Servicer in accordance with Section 8.02 hereof.
The Trustee shall notify the Rating Agencies of the resignation of the Master
Servicer. If the Master Servicer and the Securities Administrator are the same
entity, then at any time the Master Servicer is terminated as master servicer,
the Securities Administrator shall likewise be removed as securities
administrator.

     Section 7.06. Successor Master Servicer. In connection with the appointment
of any successor Master Servicer or the assumption of the duties of the Master
Servicer, MLML or the Trustee may make such arrangements for the compensation of
such successor master servicer out of payments on the Mortgage Loans as MLML or
the Trustee and such successor master servicer shall agree. If the successor
master servicer does not agree that such market value is a fair price, such
successor master servicer shall obtain two quotations of market value from third
parties actively engaged in the servicing of single-family mortgage loans.

          Notwithstanding anything herein to the contrary, in no event shall the
Trustee be liable for any Servicing Fee or master servicing fee or for any
differential in the amount of the Servicing Fee or master servicing fee paid
hereunder and the amount necessary to induce any successor servicer or successor
master servicer to act as successor servicer or successor master servicer, as
applicable, under this Agreement and the transactions set forth or provided for
herein.

     Section 7.07. Sale and Assignment of Master Servicing. The Master Servicer
may sell and assign its rights and delegate its duties and obligations in its
entirety as Master Servicer under this Agreement; provided, however, that: (i)
the purchaser or transferee accepting such assignment and delegation (a) shall
be a Person which shall be qualified to service mortgage loans for Fannie Mae or
Freddie Mac; (b) shall have a net worth of not less than $10,000,000 (unless
otherwise approved by each Rating Agency pursuant to clause (ii) below); (c)
shall be reasonably satisfactory to the Trustee (as evidenced in a writing
signed by the Trustee); and (d) shall execute and deliver to the Trustee an
agreement, in form and substance reasonably satisfactory to the Trustee, which
contains an assumption by such Person of the due and punctual performance and
observance of each covenant and condition to be performed or observed by it as
master servicer under this Agreement, any custodial agreement from and after the
effective date of such agreement; (ii) each Rating Agency shall be given prior
written notice of the identity of the proposed successor to the Master Servicer
and each Rating Agency's rating of the Certificates in effect immediately prior
to such assignment, sale and delegation will not be downgraded, qualified or
withdrawn as a result of such assignment, sale and delegation, as evidenced by a
letter to such effect delivered to the Master Servicer and the Trustee; and
(iii) the Master Servicer assigning and selling the master servicing shall
deliver to the Trustee an Officer's Certificate and


                                      -87-

<PAGE>

an Opinion of Independent Counsel, each stating that all conditions precedent to
such action under this Agreement have been completed and such action is
permitted by and complies with the terms of this Agreement. No such assignment
or delegation shall affect any liability of the Master Servicer arising prior to
the effective date thereof.

                                  ARTICLE VIII.
                                    DEFAULT

     Section 8.01. Events of Default. "Event of Default," wherever used herein,
means any one of the following events (whatever the reason for such Event of
Default and whether it shall be voluntary or involuntary or be effected by
operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body) and
only with respect to the defaulting Master Servicer:

               (i) The Master Servicer fails to cause to be deposited in the
Distribution Account any amount so required to be deposited pursuant to this
Agreement, and such failure continues unremedied for a period of three Business
Days after the date upon which written notice of such failure, requiring the
same to be remedied, shall have been given to the Master Servicer; or

               (ii) The Master Servicer fails to observe or perform in any
material respect any other material covenants and agreements set forth in this
Agreement to be performed by it, which covenants and agreements materially
affect the rights of Certificateholders, and such failure continues unremedied
for a period of 60 days after the date on which written notice of such failure,
properly requiring the same to be remedied, shall have been given to the Master
Servicer by the Trustee or to the Master Servicer and the Trustee by the Holders
of Certificates evidencing Percentage Interests aggregating not less than 25% of
the Trust Fund; or

               (iii) There is entered against the Master Servicer a decree or
order by a court or agency or supervisory authority having jurisdiction in the
premises for the appointment of a conservator, receiver or liquidator in any
insolvency, readjustment of debt, marshaling of assets and liabilities or
similar proceedings, or for the winding up or liquidation of its affairs, and
the continuance of any such decree or order is unstayed and in effect for a
period of 60 consecutive days, or an involuntary case is commenced against the
Master Servicer under any applicable insolvency or reorganization statute and
the petition is not dismissed within 60 days after the commencement of the case;
or

               (iv) The Master Servicer consents to the appointment of a
conservator or receiver or liquidator in any insolvency, readjustment of debt,
marshaling of assets and liabilities or similar proceedings of or relating to
the Master Servicer or substantially all of its property; or the Master Servicer
admits in writing its inability to pay its debts generally as they become due,
files a petition to take advantage of any applicable insolvency or
reorganization statute, makes an assignment for the benefit of its creditors, or
voluntarily suspends payment of its obligations; or

               (v) The Master Servicer assigns or delegates its duties or rights
under this Agreement in contravention of the provisions permitting such
assignment or delegation under Sections 7.05 or 7.07.


                                       -88-

<PAGE>

In each and every such case, so long as such Event of Default with respect to
the Master Servicer shall not have been remedied, either the Trustee or the
Holders of Certificates evidencing Percentage Interests aggregating not less
than 66 2/3% of the Class Certificate Balance of the Certificates, by notice in
writing to the Master Servicer (and to the Trustee if given by such
Certificateholders), with a copy to the Rating Agencies, and with the consent of
the Seller, may terminate all of the rights and obligations (but not the
liabilities) of the Master Servicer under this Agreement and in and to the
Mortgage Loans and/or the REO Property serviced by the Master Servicer and the
proceeds thereof. Upon the receipt by the Master Servicer of the written notice,
all authority and power of the Master Servicer under this Agreement, whether
with respect to the Certificates, the Mortgage Loans, REO Property or under any
other related agreements (but only to the extent that such other agreements
relate to the Mortgage Loans or related REO Property) shall, subject to Section
8.02, automatically and without further action pass to and be vested in the
Trustee pursuant to this Section 8.01; and, without limitation, the Trustee is
hereby authorized and empowered to execute and deliver, on behalf of the Master
Servicer as attorney-in-fact or otherwise, any and all documents and other
instruments and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement or assignment of the Mortgage Loans and
related documents, or otherwise. The Master Servicer agrees to cooperate with
the Trustee in effecting the termination of the Master Servicer's rights and
obligations hereunder, including, without limitation, the transfer to the
Trustee of (i) the property and amounts which are then or should be part of the
Issuing Entity or which thereafter become part of the Issuing Entity; and (ii)
originals or copies of all documents of the Master Servicer reasonably requested
by the Trustee to enable it to assume the Master Servicer's duties thereunder.
In addition to any other amounts which are then, or, notwithstanding the
termination of its activities under this Agreement, may become payable to the
Master Servicer under this Agreement, the Master Servicer shall be entitled to
receive, out of any amount received on account of a Mortgage Loan or related REO
Property, that portion of such payments which it would have received as
reimbursement under this Agreement if notice of termination had not been given.
The termination of the rights and obligations of the Master Servicer shall not
affect any obligations incurred by the Master Servicer prior to such
termination.

     Section 8.02. Trustee to Act; Appointment of Successor.

          (a) Upon the receipt by the Master Servicer of a notice of termination
pursuant to Section 8.01 or an Opinion of Independent Counsel pursuant to
Section 7.05 to the effect that the Master Servicer is legally unable to act or
to delegate its duties to a Person which is legally able to act, the Trustee
shall automatically become the successor in all respects to the Master Servicer
in its capacity under this Agreement and the transactions set forth or provided
for herein and shall thereafter be subject to all the responsibilities, duties,
liabilities and limitations on liabilities relating thereto placed on the Master
Servicer by the terms and provisions hereof; provided, however, that MLML shall
have the right to either (a) immediately assume the duties of the Master
Servicer or (b) select a successor master servicer; provided further, however,
that the Trustee shall have no obligation whatsoever with respect to any
liability (other than advances deemed recoverable and not previously made)
incurred by the Master Servicer at or prior to the time of termination. As
compensation therefor, the Trustee shall be entitled to all funds relating to
the Mortgage Loans which the Master Servicer would have been entitled to retain
if the Master Servicer had continued to act hereunder, except for


                                      -89-

<PAGE>

those amounts due the Master Servicer as reimbursement permitted under this
Agreement for advances previously made or expenses previously incurred.
Notwithstanding the above, or anything herein to the contrary, the Trustee, if
it becomes Master Servicer, shall have no responsibility or obligation (i) to
repurchase or substitute any Mortgage Loan, (ii) for any representation or
warranty of the Master Servicer hereunder, and (iii) for any act or omission of
either a predecessor or successor Master Servicer other than the Trustee. The
Trustee may conduct any activity required of it as Master Servicer hereunder
through an Affiliate or through an agent. Neither the Trustee (as successor
Master Servicer) nor any other successor Master Servicer shall be deemed to be
in default hereunder due to any act or omission of a predecessor Master
Servicer, including but not limited to failure to timely deliver to the Trustee
distribution instructions, any funds required to be deposited to the Trust Fund,
or any breach of its duty to cooperate with a transfer of master servicing.
Neither the Trustee nor any other successor Master Servicer shall be deemed to
be in default hereunder by reason of any failure to make, or any delay in
making, any distribution hereunder or any portion thereof or any failure to
perform, or any delay in performing, any duties or responsibilities hereunder,
in either case caused solely by the failure of the Master Servicer to deliver or
provide, or any delay in delivering or providing, any cash, information,
documents or records required to be provided to it by the Master Servicer.
Notwithstanding the above, the Trustee may, if it shall be unwilling so to act,
or shall, if it is legally unable so to act, appoint or petition a court of
competent jurisdiction to appoint, any established housing and home finance
institution which is a Fannie Mae- or Freddie Mac-approved servicer, and with
respect to a successor to the Master Servicer only, having a net worth of not
less than $10,000,000 and meeting such other standards for a successor Master
Servicer as are set forth in this Agreement, as the successor to the Master
Servicer hereunder in the assumption of all or any part of the responsibilities,
duties or liabilities of the Master Servicer hereunder. Pending appointment of a
successor to the Master Servicer hereunder, the Trustee shall act in such
capacity as hereinabove provided. In connection with such appointment and
assumption, the Trustee may make such arrangements for the compensation of such
successor out of payments on the Mortgage Loans as it and such successor shall
agree; provided, however, in the event that the provisions of Section 7.06 shall
apply, no such compensation shall be in excess of that permitted the Trustee
under this Subsection 8.02(a), and that such successor shall undertake and
assume the obligations of the Trustee to pay compensation to any third Person
acting as an agent or independent contractor in the performance of master
servicing responsibilities hereunder. The Trustee and such successor shall take
such action, consistent with this Agreement, as shall be necessary to effectuate
any such succession.

          (b) If the Trustee shall succeed to any duties of the Master Servicer
respecting the Mortgage Loans as provided herein, it shall do so in a separate
capacity and not in its capacity as Trustee and, accordingly, the provisions of
Article IX shall be inapplicable to the Trustee in its duties as the successor
to the Master Servicer in the servicing of the Mortgage Loans (although such
provisions shall continue to apply to the Trustee in its capacity as Trustee);
the provisions of Article VII, however, shall apply to it in its capacity as
successor master servicer.

     Section 8.03. Notification to Certificateholders. Upon any termination or
appointment of a successor to the Master Servicer, the Trustee shall give prompt
written notice thereof to Certificateholders at their respective addresses
appearing in the Certificate Register and to the Rating Agencies.


                                      -90-

<PAGE>

     Section 8.04. Waiver of Defaults. The Trustee shall transmit by mail to all
Certificateholders, within 60 days after the occurrence of any Event of Default
known to the Trustee, unless such Event of Default shall have been cured, notice
of each such Event of Default hereunder known to the Trustee. The Holders of
Certificates evidencing Percentage Interests aggregating not less than 66 2/3%
of the Class Certificate Balance of the Certificates may, on behalf of all
Certificateholders, waive any default by the Master Servicer in the performance
of its obligations hereunder and the consequences thereof, except a default in
the making of or the causing to be made any required distribution on the
Certificates. Upon any such waiver of a past default, such default shall be
deemed to cease to exist, and any Event of Default arising therefrom shall be
deemed to have been timely remedied for every purpose of this Agreement. No such
waiver shall extend to any subsequent or other default or impair any right
consequent thereon except to the extent expressly so waived. The Trustee shall
give notice of any such waiver to the Rating Agencies.

     Section 8.05. List of Certificateholders. Upon reasonable, prior written
request of three or more Certificateholders of record, for purposes of
communicating with other Certificateholders with respect to their rights under
this Agreement, the Trustee will afford such Certificateholders access during
business hours to the most recent list of Certificateholders held by the
Trustee.

                                  ARTICLE IX.
                            CONCERNING THE TRUSTEE AND
                          THE SECURITIES ADMINISTRATOR

     Section 9.01. Duties of Trustee.

          (a) The Trustee, prior to the occurrence of an Event of Default and
after the curing or waiver of all Events of Default which may have occurred, and
the Securities Administrator each undertake to perform such duties and only such
duties as are specifically set forth in this Agreement as duties of the Trustee
and the Securities Administrator, respectively. If an Event of Default has
occurred and has not been cured or waived, the Trustee shall exercise such of
the rights and powers vested in it by this Agreement, and subject to Section
8.02(b) use the same degree of care and skill in their exercise, as a prudent
person would exercise under the circumstances in the conduct of his own affairs.

          (b) Upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments which are specifically
required to be furnished to the Trustee and the Securities Administrator
pursuant to any provision of this Agreement, the Trustee and the Securities
Administrator, respectively, shall examine them to determine whether they are in
the form required by this Agreement; provided, however, that neither the Trustee
nor the Securities Administrator shall be responsible for the accuracy or
content of any resolution, certificate, statement, opinion, report, document,
order or other instrument furnished by the Master Servicer; provided, further,
that neither the Trustee nor the Securities Administrator shall be responsible
for the accuracy or verification of any calculation provided to it pursuant to
this Agreement. If any such instrument is found not to conform to the
requirements of this Agreement in a material manner, the Trustee shall take such
action as it deems appropriate to have the instrument corrected and if the
instrument is not corrected to its satisfaction, the Trustee


                                      -91-

<PAGE>

will provide notice thereof to the Certificateholders and take such further
action as directed by the Certificateholders.

          (c) On each Distribution Date, the Securities Administrator shall make
monthly distributions and the final distribution to the Certificateholders from
funds in the Distribution Account as provided in Sections 6.01 and 10.01 herein
based solely on the report of the Master Servicer and the Servicer.

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

               (i) Prior to the occurrence of an Event of Default, and after the
curing or waiver of all such Events of Default which may have occurred, the
duties and obligations of the Trustee and the Securities Administrator shall be
determined solely by the express provisions of this Agreement, neither the
Trustee nor the Securities Administrator shall be liable except for the
performance of their respective duties and obligations as are specifically set
forth in this Agreement, no implied covenants or obligations shall be read into
this Agreement against the Trustee or the Securities Administrator and, in the
absence of bad faith on the part of the Trustee or the Securities Administrator,
respectively, the Trustee or the Securities Administrator, respectively, may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon any certificates or opinions furnished to the
Trustee or the Securities Administrator, respectively, and conforming to the
requirements of this Agreement;

               (ii) Neither the Trustee nor the Securities Administrator shall
be liable in its individual capacity for an error of judgment made in good faith
by a Responsible Officer or Responsible Officers of the Trustee or an officer of
the Securities Administrator, respectively, unless it shall be proved that the
Trustee or the Securities Administrator, respectively, was negligent in
ascertaining the pertinent facts;

               (iii) Neither the Trustee nor the Securities Administrator shall
be liable with respect to any action taken, suffered or omitted to be taken by
it in good faith in accordance with the directions of the Holders of
Certificates evidencing Percentage Interests aggregating not less than 25% of
the Class Certificate Balance of the Certificates, if such action or non-action
relates to the time, method and place of conducting any proceeding for any
remedy available to the Trustee or the Securities Administrator, respectively,
or exercising any trust or other power conferred upon the Trustee or the
Securities Administrator, respectively, under this Agreement;

               (iv) The Trustee shall not be required to take notice or be
deemed to have notice or knowledge of any default or Event of Default unless a
Responsible Officer of the Trustee's Corporate Trust Office shall have actual
knowledge thereof. In the absence of such notice, the Trustee may conclusively
assume there is no such default or Event of Default;

               (v) The Trustee shall not in any way be liable by reason of any
insufficiency in any Account held by or in the name of Trustee unless it is
determined by a court of competent jurisdiction that the Trustee's gross
negligence or willful misconduct was the primary cause of such insufficiency
(except to the extent that the Trustee is obligor and has defaulted thereon);


                                      -92-

<PAGE>

               (vi) Anything in this Agreement to the contrary notwithstanding,
in no event shall the Trustee or the Securities Administrator be liable for
special, indirect or consequential loss or damage of any kind whatsoever
(including but not limited to lost profits), even if the Trustee or the
Securities Administrator, respectively, has been advised of the likelihood of
such loss or damage and regardless of the form of action; and

               (vii) None of the Securities Administrator, the Depositor, the
Master Servicer, the Servicer or the Trustee shall be responsible for the acts
or omissions of the other, it being understood that this Agreement shall not be
construed to render them partners, joint venturers or agents of one another.

     Neither the Trustee nor the Securities Administrator shall be required to
expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if there is reasonable ground for believing that the repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it, and none of the provisions contained in this Agreement
shall in any event require the Trustee or the Securities Administrator to
perform, or be responsible for the manner of performance of, any of the
obligations of the Master Servicer hereunder or under the Servicing Agreement,
except during such time, if any, as the Trustee shall be the successor to, and
be vested with the rights, duties, powers and privileges of, the Master Servicer
in accordance with the terms of this Agreement.

          (e) All funds received by the Master Servicer and the Securities
Administrator and required to be deposited in the Master Servicer Collection
Account or Distribution Account pursuant to this Agreement will be promptly so
deposited by the Master Servicer and the Securities Administrator.

          (f) Except for those actions that the Trustee or the Securities
Administrator is required to take hereunder, neither the Trustee nor the
Securities Administrator shall have any obligation or liability to take any
action or to refrain from taking any action hereunder in the absence of written
direction as provided hereunder.

     Section 9.02. Certain Matters Affecting the Trustee and the Securities
Administrator. Except as otherwise provided in Section 9.01:

               (i) The Trustee and the Securities Administrator may rely and
shall be protected in acting or refraining from acting in reliance on any
resolution, certificate of a Depositor, Master Servicer or Servicer, certificate
of auditors or any other certificate, statement, instrument, opinion, report,
notice, request, consent, order, appraisal, bond or other paper or document
believed by it to be genuine and to have been signed or presented by the proper
party or parties;

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


                                       -93-

<PAGE>

               (iii) Neither the Trustee nor the Securities Administrator shall
be under any obligation to exercise any of the trusts or powers vested in it by
this Agreement, other than its obligation to give notices pursuant to this
Agreement, or to institute, conduct or defend any litigation hereunder or in
relation hereto at the request, order or direction of any of the
Certificateholders pursuant to the provisions of this Agreement, unless such
Certificateholders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which may be incurred
therein or thereby. Nothing contained herein shall, however, relieve the Trustee
of the obligation, upon the occurrence of an Event of Default of which a
Responsible Officer of the Trustee's Corporate Trust Office has actual knowledge
(which has not been cured or waived), subject to Section 8.02(b), to exercise
such of the rights and powers vested in it by this Agreement, and to use the
same degree of care and skill in their exercise, as a prudent person would
exercise under the circumstances in the conduct of his own affairs;

               (iv) Prior to the occurrence of an Event of Default hereunder and
after the curing or waiver of all Events of Default which may have occurred,
neither the Trustee nor the Securities Administrator shall be liable in its
individual capacity for any action taken, suffered or omitted by it in good
faith and believed by it to be authorized or within the discretion or rights or
powers conferred upon it by this Agreement;

               (v) Neither the Trustee nor the Securities Administrator shall be
bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, bond or other paper or document, unless
requested in writing to do so by Holders of Certificates evidencing Percentage
Interests aggregating not less than 25% of the Class Certificate Balance of the
Certificates and provided that the payment within a reasonable time to the
Trustee or the Securities Administrator, as applicable, of the costs, expenses
or liabilities likely to be incurred by it in the making of such investigation
is, in the opinion of the Trustee or the Securities Administrator, as
applicable, reasonably assured to the Trustee or the Securities Administrator,
as applicable, by the security afforded to it by the terms of this Agreement.
The Trustee or the Securities Administrator may require reasonable indemnity
against such expense or liability as a condition to taking any such action. The
reasonable expense of every such examination shall be paid by the
Certificateholders requesting the investigation;

                (vi) The Trustee and the Securities Administrator may execute any
of the trusts or powers hereunder or perform any duties hereunder either
directly or through Affiliates, agents or attorneys; provided, however, that the
Trustee may not appoint any agent to perform its custodial functions with
respect to the Mortgage Files or paying agent functions under this Agreement
without the express written consent of the Securities Administrator, which
consent will not be unreasonably withheld. Neither the Trustee nor the
Securities Administrator shall be liable or responsible for the misconduct or
negligence of any of the Trustee's or the Securities Administrator's agents or
attorneys or a custodian or paying agent appointed hereunder by the Trustee or
the Securities Administrator with due care and, when required, with the consent
of the Securities Administrator;

               (vii) Should the Trustee or the Securities Administrator deem the
nature of any action required on its part, other than a payment or transfer
under Subsection 4.01(b) or Section 4.02, to be unclear, the Trustee or the
Securities Administrator, respectively, may require prior to such action that it
be provided by the Depositor with reasonable further instructions;


                                       -94-

<PAGE>

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

               (ix) Neither the Trustee nor the Securities Administrator shall
be required to give any bond or surety with respect to the execution of the
trust created hereby or the powers granted hereunder, except as provided in
Subsection 9.07; and

               (x) Neither the Trustee nor the Securities Administrator shall
have any duty to conduct any affirmative investigation as to the occurrence of
any condition requiring the repurchase of any Mortgage Loan by the Seller
pursuant to this Agreement or the Mortgage Loan Purchase Agreement, as
applicable, or the eligibility of any Mortgage Loan for purposes of this
Agreement.

                (xi) Any permissive right of the Trustee or Securities
Administrator hereunder shall not be construed as a duty.

     Section 9.03. Trustee and Securities Administrator Not Liable for
Certificates or Mortgage Loans. The recitals contained herein and in the
Certificates (other than the signature and countersignature of the Securities
Administrator on the Certificates) shall be taken as the statements of the
Depositor, and neither the Trustee nor the Securities Administrator shall have
any responsibility for their correctness. Neither the Trustee nor the Securities
Administrator makes any representation as to the validity or sufficiency of the
Certificates (other than the signature and countersignature of the Securities
Administrator on the Certificates) or of any Mortgage Loan except as expressly
provided in Sections 2.02 and 2.05 hereof; provided, however, that the foregoing
shall not relieve the Trustee or the Custodian of the obligation to review the
Mortgage Files pursuant to Sections 2.02 and 2.04. The Securities
Administrator's signature and countersignature (or countersignature of its
agent) on the Certificates shall be solely in its capacity as Securities
Administrator of the Trust Fund and shall not constitute the Certificates an
obligation of the Securities Administrator in any other capacity. Neither the
Trustee or the Securities Administrator shall be accountable for the use or
application by the Depositor of any of the Certificates or of the proceeds of
such Certificates, or for the use or application of any funds paid to the
Depositor with respect to the Mortgage Loans. Subject to the provisions of
Section 2.05, neither the Trustee nor the Securities Administrator shall be
responsible for the legality or validity of this Agreement or any document or
instrument relating to this Agreement, the validity of the execution of this
Agreement or of any supplement hereto or instrument of further assurance, or the
validity, priority, perfection or sufficiency of the security for the
Certificates issued hereunder or intended to be issued hereunder. Neither the
Trustee nor the Securities Administrator shall at any time have any
responsibility or liability for or with respect to the legality, validity and
enforceability of any Mortgage or any Mortgage Loan, or the perfection and
priority of any Mortgage or the maintenance of any such perfection and priority,
or for or with respect to the sufficiency of the Trust Fund or its ability to
generate the payments to be distributed to Certificateholders, under this
Agreement. Neither the Trustee nor the Securities Administrator shall have any
responsibility for filing any financing or continuation statement in any public
office at any time or to otherwise perfect or maintain the perfection of any
security interest or lien granted to it hereunder or to record this Agreement.

     Section 9.04. Trustee and Securities Administrator May Own Certificates.
The Trustee and the Securities Administrator in its individual capacity or in
any capacity other than as Trustee or Securities Administrator hereunder may
become the owner or pledgee of any Certificates with the same rights it would
have if it were not Trustee or the Securities Administrator, as applicable, and
may otherwise deal with the parties hereto.

     Section 9.05. Trustee's and Securities Administrator's Fees and Expenses.
The fees and expenses of the Trustee and the Securities Administrator shall be
paid by the Master Servicer in accordance with a side letter agreement. In
addition, the Trustee and the Securities Administrator will be entitled to
recover from the Master Servicer Collection Account pursuant to Section 4.03(b)
all reasonable out-of-pocket expenses, disbursements and advances and the
expenses of the Trustee and the Securities Administrator, respectively, in
connection with any Event of Default, any breach of this Agreement or any claim
or legal action (including any pending or threatened claim or legal action)
incurred or made by the Trustee or the Securities Administrator, respectively,
in the administration of the trusts hereunder (including the reasonable
compensation, expenses and disbursements of its counsel) except any such

compensation of a trustee of an express trust.

     Section 9.06. Eligibility Requirements for Trustee and Securities
Administrator.

          (a) The Trustee and any successor Trustee and the Securities
Administrator and any successor Securities Administrator shall during the entire
duration of this Agreement be a state bank or trust company or a national
banking association organized and doing business under the laws of such state or
the United States of America, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus and undivided profits of at
least $40,000,000 or, in the case of a successor Trustee, $50,000,000, subject
to supervision or examination by federal or state authority and, in the case of
the Trustee, rated "BBB" or higher by S&P and "Aaa1" or higher by Moody's with
respect to their long-term rating and rated "BBB" or higher by S&P and "Baa1" or
higher by Moody's with respect to any outstanding long-term unsecured
unsubordinated debt, and, in the case of a successor Trustee or successor
Securities Administrator other than pursuant to Section 9.10, rated in one of
the two highest long-term debt categories of, or otherwise acceptable to, each
of the Rating Agencies. If the Trustee publishes reports of condition at least
annually, pursuant to law or to the requirements of the aforesaid supervising or
examining authority, then for the purposes of this Section 9.06 the combined
capital and surplus of such corporation shall be deemed to be its total equity
capital (combined capital and surplus) as set forth in its most recent report of
condition so published. In case at any time the Trustee or the Securities
Administrator shall cease to be eligible in accordance with the provisions of
this Section 9.06, the Trustee or the Securities Administrator shall resign
immediately in the manner and with the effect specified in Section 9.08.

          (b) In addition, the Securities Administrator (i) may not be an
originator, Master Servicer, Servicer, the Depositor or an affiliate of the
Depositor unless the Securities Administrator is in an institutional trust
department of the relevant entity, (ii) must be authorized

to exercise corporate trust powers under the laws of its jurisdiction of
organization, and (iii) must be rated at least "A" by S&P or "A" Moody's. If no
successor Securities Administrator shall have been appointed and shall have
accepted appointment within 60 days after the Securities Administrator ceases to
be the Securities Administrator pursuant to Section 9.08, then the Trustee shall
either (i) perform the duties of the Securities Administrator pursuant to this
Agreement until such time as a new Securities Administrator is appointed or (ii)
petition a court of competent jurisdiction to appoint a successor securities
administrator. The Trustee shall notify the Rating Agencies of any change of
Securities Administrator.

     Section 9.07. Insurance. The Securities Administrator, at its own expense,
shall at all times maintain and keep in full force and effect: (i) fidelity
insurance, (ii) theft of documents insurance and (iii) forgery insurance (which
may be collectively satisfied by a "Financial Institution Bond" and/or a
"Bankers' Blanket Bond"). All such insurance shall be in amounts, with standard
coverage and subject to deductibles, as are customary for insurance typically
maintained by banks or their affiliates which act as custodians for
investor-owned mortgage pools. A certificate of an officer of the Securities
Administrator as to the Securities Administrator's compliance with this Section
9.07 shall be furnished to any Certificateholder upon reasonable written
request.

     Section 9.08. Resignation and Removal of the Trustee and Securities
Administrator.

resign and be discharged from the trust hereby created by giving written notice
thereof to the Depositor and the Master Servicer, with a copy to the Rating
Agencies. Upon receiving such notice of resignation, the Depositor shall
promptly appoint a successor Trustee or successor Securities Administrator, as
applicable, by written instrument, in triplicate, one copy of which instrument
shall be delivered to each of the resigning Trustee or Securities Administrator,
as applicable, the successor Trustee or Securities Administrator, as applicable.
If no successor Trustee or Securities Administrator shall have been so appointed
and have accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Trustee or Securities Administrator may petition any
court of competent jurisdiction for the appointment of a successor Trustee or
Securities Administrator. If the Securities Administrator and the Master
Servicer are the same entity, then at any time the Securities Administrator
resigns or is removed as Securities Administrator, the Master Servicer shall
likewise be terminated as Master Servicer.

          (b) If at any time the Trustee or the Securities Administrator shall
cease to be eligible in accordance with the provisions of Section 9.06 and shall
fail to resign after written request therefor by the Depositor or if at any time
the Trustee or the Securities Administrator shall become incapable of acting, or
shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or the
Securities Administrator, as applicable, or of its property shall be appointed,
or any public officer shall take charge or control of the Trustee or the
Securities Administrator, as applicable, or of its property or affairs for the
purpose of rehabilitation, conservation or liquidation, then the Depositor shall
promptly remove the Trustee, or shall be entitled to remove the Securities
Administrator, as applicable, and appoint a successor Trustee or Securities
Administrator, as applicable, by written instrument, in triplicate, one copy of
which instrument shall be delivered to each of the Trustee or Securities

          (a) Any successor Trustee or Securities Administrator appointed as
provided in Section 9.08 shall execute, acknowledge and deliver to the
Depositor, the Master Servicer and its predecessor Trustee or Securities
Administrator an instrument accepting such appointment hereunder. The
resignation or removal of the predecessor Trustee or Securities Administrator
shall then become effective and such successor Trustee or Securities
Administrator, without any further act, deed or conveyance, shall become fully
vested with all the rights, powers, duties and obligations of its predecessor
hereunder, with like effect as if originally named as Trustee or Securities
Administrator herein. The predecessor Trustee or Securities Administrator shall

<PAGE>

or any state bank or trust company or national banking association succeeding to
all or substantially all of the corporate trust business of the Trustee or the
Securities Administrator, respectively, shall be the successor of the Trustee or
the Securities Administrator, respectively, hereunder, provided such state bank
or trust company or national banking association shall be eligible under the
provisions of Section 9.06. Such succession shall be valid without the execution
or filing of any paper or any further act on the part of any of the parties
hereto, anything herein to the contrary notwithstanding.

     Section 9.11. Appointment of Co-Trustee or Separate Trustee.

          (a) Notwithstanding any other provisions hereof, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust or property constituting the same may at the time be located, the
Depositor and the Trustee acting jointly shall have the power and shall execute
and deliver all instruments to appoint one or more Persons approved by the
Trustee and the Depositor to act as co-trustee or co-trustees, jointly with the
Trustee, or separate trustee or separate trustees, of all or any part of the
Trust, and to vest in such Person or Persons, in such capacity, such title to

co-trustee(s) or separate trustee(s) shall be required under Section 9.08
hereof.

          (d) In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 9.11, all rights, powers, duties and obligations
conferred or imposed upon the Trustee and required to be conferred on such
co-trustee shall be conferred or imposed upon and exercised or performed by the
Trustee and such separate trustee or co-trustee jointly, except to the extent
that under any law of any jurisdiction in which any particular act or acts are
to be performed (whether as Trustee hereunder or as successor to the Master
Servicer hereunder), the Trustee shall be incompetent or unqualified to perform
such act or acts, in which event such rights, powers, duties and obligations
(including the holding of title to the Trust or any portion thereof in any such
jurisdiction) shall be exercised and performed by such separate trustee or
co-trustee at the direction of the Trustee.

          (e) Any notice, request or other writing given to the Trustee shall be

separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article IX. Each separate trustee and co-trustee, upon its acceptance of

this Agreement on its behalf and in its name. If any separate trustee or
co-trustee shall die, become incapable of acting, resign or be removed, all of
its estates, properties rights, remedies and trusts shall vest in and be
exercised by the Trustee, to the extent permitted by law, without the
appointment of a new or successor Trustee.

          (g) No Trustee under this Agreement shall be personally liable by
reason of any act or omission of another Trustee under this Agreement. The
Depositor and the Trustee acting jointly may at any time accept the resignation
of or remove any separate trustee or co-trustee.

extent that (i) such expenses are ordinary or routine expenses, including
expenses of a routine audit but not expenses of litigation (except as described
in (ii)); or (ii) such expenses or liabilities (including taxes and penalties)
are attributable to the negligence or willful misconduct of the Securities
Administrator in fulfilling its duties hereunder (including its duties as tax
return preparer). The Securities Administrator shall be entitled to
reimbursement of expenses to the extent provided in clause (i) above from the
Distribution Account, provided, however, the Securities Administrator shall not

governmental authority such information as is necessary for the application of
any tax relating to the transfer of a Residual Certificate to any disqualified
person or organization pursuant to Treasury Regulation 1.860E-2(a)(5) and any
person designated in Section 860E(e)(3) of the Code.

          (g) The Securities Administrator and the Holders of Certificates shall
take any action or cause any REMIC to take any action necessary to create or
maintain the status of any REMIC as a REMIC under the REMIC Provisions and shall
assist each other as necessary to create or maintain such status. Neither the
Securities Administrator nor the Holder of any Residual Certificate shall
knowingly take any action, cause any REMIC to take any action or fail to take
