     POOLING AND SERVICING AGREEMENT, dated as of December 1, 2006, among
MERRILL LYNCH MORTGAGE INVESTORS, INC., a Delaware corporation, as depositor
(the "Depositor"), WILSHIRE CREDIT CORPORATION, a Nevada corporation, as
servicer (the "Servicer"), and LASALLE BANK NATIONAL ASSOCIATION, a national
banking association, as trustee (the "Trustee").

     The Depositor is the owner of the Trust Fund that is hereby conveyed to the
Trustee in return for the Certificates. The Trust Fund for federal income tax
purposes will consist of (i) three real estate mortgage investment conduits,
(ii) the right to receive payments distributable to the Class P Certificates
pursuant to Section 4.04(b)(i) hereof, (iii) each Cap Contract and the Cap
Contract Account, (iv) the grantor trusts described in Section 2.07 hereof and
(v) the Supplemental Interest Trust, which in turn will hold the Swap Agreement.
The SWAP REMIC will consist of all of the assets constituting the Trust Fund
(other than the assets described in clauses (ii), (iii), (iv) and (v) above,
other than the SWAP REMIC Regular Interests and other than the Lower Tier REMIC
Regular Interests) and will be evidenced by the SWAP REMIC Regular Interests
(which will be uncertificated and will represent the "regular interests" in the
SWAP REMIC) and the Class SWR Interest as the single "residual interest" in the
SWAP REMIC. The Lower Tier REMIC will consist of SWAP REMIC Regular Interests
and will be evidenced by the Lower Tier REMIC Regular Interests (which will be
uncertificated and will represent the "regular interests" in the Lower Tier
REMIC) and the Class LTR Interest as the single "residual interest" in the Lower
Tier REMIC. The Trustee on behalf of the Trust will hold the Lower Tier REMIC
Regular Interests. The Upper Tier REMIC will consist of the Lower Tier REMIC
Regular Interests and will be evidenced by the REMIC Regular Interests (which
will represent the "regular interests" in the Upper Tier REMIC) and the Residual
Interest as the single "residual interest" in the Upper Tier REMIC. The Class R
Certificate will represent beneficial ownership of the Class SWR Interest, the
Class LTR Interest and the Residual Interest. The "latest possible maturity
date" for federal income tax purposes of all interests created hereby will be
the Latest Possible Maturity Date.

     All covenants and agreements made by the Sponsor in the Sale Agreement and
by the Depositor and the Trustee herein with respect to the Mortgage Loans and
the other property constituting the Trust Fund are for the benefit of the
Holders from time to time of the Certificates and, to the extent provided
herein, the NIMs Insurer.

(1)  The initial principal balance of each of these Lower Tier REMIC Regular
     Interests shall equal 1/4 of the initial Certificate Principal Balance of
     its Corresponding Certificates.

(2)  The initial principal balance of the Class LTIX Interest shall equal the
     excess of (i) 50% of the aggregate Cut-off Date Principal Balance of the
     Mortgage Loans over (ii) the initial principal balance of the Lower Tier
     REMIC I Marker Interests.

(3)  The initial principal balance of the Class LTII1A Interest shall equal
     0.05% of the excess of (i) the aggregate Cut-off Date Principal Balance of
     the Group One Mortgage Loans over (ii) the aggregate of the initial
     Certificate Principal Balances of Certificate Group One.

(4)  The initial principal balance of the Class LTII1B Interest shall equal
     0.05% of the aggregate Cut-off Date Principal Balance of the Group One
     Mortgage Loans.

     Certificate Principal Balances of Certificate Group Two.

(6)  The initial principal balance of the Class LTII2B Interest shall equal
     0.05% of the aggregate Cut-off Date Principal Balance of the Group Two
     Mortgage Loans.

     REMIC II Marker Interests.

(8)  For each Distribution Date, the interest rate for each of the Lower Tier
     REMIC Regular Interests (other than the Class LTII1B, the Class LTII2B and
     the Class LT-IO Interests) shall be a per annum rate (but not less than
     zero) equal to the product of (i) the weighted average of the interest
     rates on the SWAP REMIC Regular Interests for such Distribution Date and
     (ii) a fraction the numerator of which is 30 and the denominator of which
     is the actual number of days in the Accrual Period for the LIBOR
     Certificates, provided however, that for any Distribution Date on which the
     Class LT-IO Interest is entitled to a portion of interest accruals on a
     SWAP REMIC Regular Interest ending with a designation "A" as described in
     footnote 11 below, such weighted average shall be computed by first
     subjecting the rate on such SWAP REMIC Regular Interest to a cap equal to
     Swap LIBOR for such Distribution Date.

(9)  For each Distribution Date, the interest rate for the Class LTII1B Interest
     shall be a per annum rate equal to the product of (i) the weighted average
     of the interest rates on the SWAP REMIC Regular Interests beginning with
     the designation "1" for such Distribution Date and (ii) a fraction the
     numerator of which is 30 and the denominator of which is the actual number
     of days in the Accrual Period for the LIBOR Certificates, provided,
     however, that for any Distribution Date on which the Class LT-IO Interest
     is entitled to a portion of interest accruals on a SWAP REMIC Regular
     Interest ending with a designation "A" as described in footnote 11 below,
     such weighted average shall be computed by first subjecting the rate on
     such SWAP REMIC Regular Interest to a cap equal to Swap LIBOR for such
     Distribution Date.

(10) For each Distribution Date, the interest rate for the Class LTII2B Interest
     shall be a per annum rate equal to the product of (i) the weighted average
     of the interest rates on the SWAP REMIC Regular Interests beginning with
     the designation "2" for such Distribution Date and (ii) a fraction the
     numerator of which is 30 and the denominator of which is the actual number
     of days in the Accrual Period for the LIBOR Certificates, provided,
     however, that for any Distribution Date on which the Class LT-IO Interest
     is entitled to a portion of interest accruals on a SWAP REMIC Regular
     Interest ending with a designation "A" as described in footnote 11 below,
     such weighted average shall be computed by first subjecting the rate on
     such SWAP REMIC Regular Interest to a cap equal to Swap LIBOR for such
     Distribution Date.

(11) The Class LT-IO Interest is an interest-only class that does not have a
     principal balance. For only those Distribution Dates listed in the first
     column of the table below, the Class LT-IO Interest shall be entitled to
     interest accrued on the SWAP REMIC Regular Interest listed in the second
     column below at a per annum rate equal to the excess, if any, of (i) the
     interest rate for such SWAP REMIC Regular Interest for such Distribution
     Date over (ii) Swap LIBOR for such Distribution Date.

as of the close of business on the related Determination Date, except as
provided in Section 4.01 hereof, less the aggregate amount of any such
Delinquent payments that the Servicer has determined would constitute a

any Affiliate of the Depositor shall be deemed not to be Outstanding and the
Percentage Interest evidenced thereby shall not be taken into account in
determining whether the requisite amount of Percentage Interests necessary to
effect such consent has been obtained; provided, however, that if any such
Person (including the Depositor) owns 100% of the Percentage Interests evidenced

                          CONVEYANCE OF MORTGAGE LOANS;
                         REPRESENTATIONS AND WARRANTIES

     SECTION 2.01. Conveyance of Mortgage Loans

     The Depositor, concurrently with the execution and delivery hereof, does
hereby sell, transfer, assign, set over and convey to the Trustee without
recourse all the right, title and interest of the Depositor in and to the assets
of the Trust Fund. Such assignment includes all interest and principal received
on or with respect to the Mortgage Loans on or after the Cut-off Date (other
than Scheduled Payments due on the Mortgage Loans on or before the Cut-off
Date).

     It is agreed and understood by the Depositor, the Servicer and the Trustee
that it is not intended that any Mortgage Loan be included in the Trust that is,
without limitation, either (i) a "High-Cost Home Loan" as defined in the New
Jersey Home Ownership Act effective November 27, 2003; (ii) a "High-Cost Home
Loan" as defined in the New Mexico Home Loan Protection Act effective January 1,
2004; (iii) a "High-Cost Home Mortgage Loan" as defined in the Massachusetts
Predatory Home Loan Practices Act effective November 7, 2004; (iv) a "High-Cost
Home Loan" as defined by the Indiana High Cost Home Loan Law effective January
1, 2005 or (v) a "High-Cost Home Loan" as defined by the Illinois High Risk Home
Loan Act effective January 1, 2004.

                                      -61-

<PAGE>

     In connection with such assignment, the Depositor does hereby deliver to,
and deposit with the Trustee the following documents or instruments with respect
to each Mortgage Loan:

          (A) The original Mortgage Note endorsed in blank or, "Pay to the order
     of LaSalle Bank National Association, as trustee for the Merrill Lynch
     Mortgage Investors Trust, Mortgage Loan Asset-Backed Certificates, Series
     2006-HE6, without recourse" together with all riders thereto. The Mortgage
     Note shall include all intervening endorsements showing a complete chain of
     the title from the Transferor to [____________________].

          (B) Except as provided below and for each Mortgage Loan that is not a
     MERS Loan, the original recorded Mortgage together with all riders thereto,
     with evidence of recording thereon, or, if the original Mortgage has not
     yet been returned from the recording office, a copy of the original
     Mortgage together with all riders thereto certified to be a true copy of
     the original of the Mortgage that has been delivered for recording in the
     appropriate recording office of the jurisdiction in which the Mortgaged
     Property is located and in the case of each MERS Loan, the original
     Mortgage together with all riders thereto, noting the presence of the MIN
     of the Loan and either language indicating that the Mortgage Loan is a MOM
     Loan or if the Mortgage Loan was not a MOM Loan at origination, the
     original Mortgage and the assignment thereof to MERS, with evidence of
     recording indicated thereon, or a copy of the Mortgage certified by the
     public recording office in which such Mortgage has been recorded.

          (C) In the case of each Mortgage Loan that is not a MERS Loan, the
     original Assignment of each Mortgage in blank or, to "LaSalle Bank National
     Association, as trustee for the Merrill Lynch Mortgage Investors Trust,
     Mortgage Loan Asset-Backed Certificates, Series 2006-HE6."

          (D) The original policy of title insurance (or a preliminary title
     report, commitment or binder if the original title insurance policy has not
     been received from the title insurance company).

          (E) Originals of any intervening assignments of the Mortgage, with
     evidence of recording thereon or, if the original intervening assignment
     has not yet been returned from the recording office, a copy of such
     assignment certified to be a true copy of the original of the assignment
     which has been sent for recording in the appropriate jurisdiction in which
     the Mortgaged Property is located.

          (F) Originals of all assumption and modification agreements, if any.

          (G) If in connection with any Mortgage Loan, the Depositor cannot
     deliver the Mortgage, Assignments of Mortgage or assumption, consolidation
     or modification, as the case may be, with evidence of recording thereon, if
     applicable, concurrently with the execution and delivery of this Agreement
     solely because of a delay caused by the public recording office where such
     Mortgage, Assignments of Mortgage or assumption, consolidation or
     modification, as the case may be, has been delivered for recordation, the
     Depositor shall deliver or cause to be delivered to the Trustee written
     notice stating that such Mortgage or assumption, consolidation or
     modification, as the case may be, has been delivered to the appropriate
     public recording office for recordation. Thereafter, the Depositor shall
     deliver or cause to be delivered to the Trustee such Mortgage, Assignments
     of Mortgage or assumption, consolidation or modification, as the case may
     be, with evidence of recording indicated thereon, if applicable, upon
     receipt thereof from the public recording office. To the extent any
     required endorsement is not contained on a Mortgage

                                      -62-

<PAGE>

     Note or an Assignment of Mortgage, the Depositor shall make or cause to be
     made such endorsement.

          (H) With respect to any Mortgage Loan, none of the Depositor, the
     Servicer or the Trustee shall be obligated to cause to be recorded the
     Assignment of Mortgage referred to in this Section 2.01. In the event an
     Assignment of Mortgage is not recorded, the Servicer and the Trustee shall
     have no liability for their failure to receive and act on notices related
     to such Assignment of Mortgage.

     The ownership of each Mortgage Note, the Mortgage and the contents of the
related Mortgage File is vested in the Trustee on behalf of the
Certificateholders. Neither the Depositor nor the Servicer shall take any action
inconsistent with such ownership and shall not claim any ownership interest
therein. The Depositor and the Servicer shall respond to any third party
inquiries with respect to ownership of the Mortgage Loans by stating that such
ownership is held by the Trustee on behalf of the Certificateholders. Mortgage
documents relating to the Mortgage Loans not delivered to the Trustee are and
shall be held in trust by the Servicer, for the benefit of the Trustee as the
owner thereof, and the Servicer's possession of the contents of each Mortgage
File so retained is for the sole purpose of servicing the related Mortgage Loan,
and such retention and possession by the Servicer, is in a custodial capacity
only. The Depositor agrees to take no action inconsistent with the Trustee's
ownership of the Mortgage Loans, to promptly indicate to all inquiring parties
that the Mortgage Loans have been sold and to claim no ownership interest in the
Mortgage Loans.

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

     In addition to the conveyance made in the first paragraph of this Section
2.01, the Depositor does hereby convey, assign and set over to the Trustee for
the benefit of the Certificateholders its rights and interests under the Sale
Agreement, including the Depositor's right, title and interest in the
representations and warranties contained in the Sale Agreement, the rights in
the Transfer Agreements described therein, and the benefit of the repurchase
obligations and the obligation of the Sponsor contained in the Sale Agreement to
take, at the request of the Depositor or the Trustee, all action on its part
which is reasonably necessary to ensure the enforceability of a Mortgage Loan.
The Trustee hereby accepts such assignment, and shall be entitled to exercise
all rights of the Depositor under the Sale Agreement as if, for such purpose, it
were the Depositor. The foregoing sale, transfer, assignment, set-over, deposit
and

                                      -63-

<PAGE>

conveyance does not and is not intended to result in creation or assumption by
the Trustee of any obligation of the Depositor, the Sponsor, or any other Person
in connection with the Mortgage Loans or any other agreement or instrument
relating thereto.

     SECTION 2.02. Acceptance by the Trustee of the Mortgage Loans

     Except as set forth in the exception report delivered contemporaneously
herewith (the "Exception Report"), the Trustee acknowledges receipt of the
Mortgage Note for each Mortgage Loan and delivery of a Mortgage File (but does
not acknowledge receipt of all documents required to be included in such
Mortgage File) with respect to each Mortgage Loan and declares that it holds and
will hold such documents and any other documents constituting a part of the
Mortgage Files delivered to it in trust for the use and benefit of all present
and future Certificateholders. The Depositor will cause the Sponsor to
repurchase any Mortgage Loan to which a material exception was taken in the
Exception Report unless such exception is cured to the satisfaction of the
Depositor and the Trustee within 45 Business Days of the Closing Date.

     The Trustee acknowledges receipt of the three Cap Contracts (forms of which
are attached hereto as Exhibits M-1, M-2 and M-3) and is hereby authorized and
instructed to enter into such contracts not in its individual capacity but
solely as trustee for the Supplemental Interest Trust, and is further directed
to execute and deliver the Transfer Agreements, the Bring Down Letters and the
Sale Agreement.

     The Trustee acknowledges receipt of the Swap Agreement that will be held in
the Supplemental Interest Trust and is hereby instructed to enter into the Swap
Agreement, not in its individual capacity, but solely as trustee for the
Supplemental Interest Trust.

     The Trustee agrees, for the benefit of Certificateholders, and the NIMs
insurer, to review each Mortgage File delivered to it within 60 days after the
Closing Date to ascertain and to certify, within 70 days of the Closing Date, to
the NIMs Insurer, the Depositor and the Servicer that all documents required by
Section 2.01 (A)-(B), (C) (if applicable), and (D)-(E), and the documents if
actually received by it, under Section 2.01(F), have been executed and received,
and that such documents relate to the Mortgage Loans identified in Exhibit B-1
that have been conveyed to it. It is herein acknowledged that, in conducting
such review, the Trustee shall not be under any duty or obligation to inspect,
review or examine any such documents, instruments, certificates or other papers
to determine that they are genuine, enforceable or appropriate for the
represented purpose, that they have actually been recorded or that they are
other than what they purport to be on their face. If the Trustee finds any
document or documents constituting a part of a Mortgage File to be missing or
defective (that is, mutilated, damaged, defaced or unexecuted) in any material
respect, the Trustee shall promptly (and in any event within no more than five
Business Days) after such finding so notify the NIMs Insurer, the Servicer, the
Sponsor and the Depositor. In addition, the Trustee shall also notify the NIMs
Insurer, the Servicer, the Sponsor and the Depositor if the original Mortgage
with evidence of recording thereon with respect to a Mortgage Loan is not
received within 70 days of the Closing Date; if it has not been received because
of a delay caused by the public recording office where such Mortgage has been
delivered for recordation, the Depositor shall deliver or cause to be delivered
to the Trustee written notice stating that such Mortgage has been delivered to
the appropriate public recording office for recordation and thereafter the
Depositor shall deliver or cause to be delivered such Mortgage with evidence of
recording thereon upon receipt thereof from the public recording office. The
Trustee shall request that the Sponsor correct or cure such omission, defect or
other irregularity, or substitute a Mortgage Loan pursuant to the provisions of
Section 2.03(c), within 90 days from the date the Sponsor was notified of such
omission or defect and, if the Sponsor does not correct or cure such omission or
defect within such period, that the Sponsor purchase such Mortgage Loan from the
Issuing Entity within 90 days from the date the Trustee notified the

                                      -64-

<PAGE>

Sponsor of such omission, defect or other irregularity at the Purchase Price of
such Mortgage Loan. The Purchase Price for any Mortgage Loan purchased pursuant
to this Section 2.02 shall be paid to the Servicer and deposited by the Servicer
in the Certificate Account or Collection Account, as appropriate, promptly upon
receipt, and upon receipt by the Trustee of written notification of such deposit
signed by a Servicing Officer or receipt of such deposit by the Trustee, upon
receipt of a Request for Release and certification of the Servicer of such
required deposit, shall promptly release to the Sponsor the related Mortgage
File and the Trustee shall execute and deliver such instruments of transfer or
assignment, without recourse, as shall be requested by the Sponsor and necessary
to vest in the Sponsor or its designee, as the case may be, any Mortgage Loan
released pursuant hereto, and the Trustee shall have no further responsibility
with regard to such Mortgage Loan. It is understood and agreed that the
obligation of the Sponsor to purchase, cure or substitute any Mortgage Loan as
to which a material defect in or omission of a constituent document exists shall
constitute the sole remedy respecting such defect or omission available to the
Trustee on behalf of Certificateholders and the NIMs Insurer. The preceding
sentence shall not, however, limit any remedies available to the
Certificateholders, the NIMs Insurer, the Depositor or the Trustee pursuant to
the Sale Agreement, the Transfer Agreements and or the Bring Down Letters. The
Trustee shall be under no duty or obligation to inspect, review and examine such
documents, instruments, certificates or other papers to determine that they are
genuine, enforceable, recordable, duly authorized, sufficient, legal, valid or
appropriate to the represented purpose, or that they have actually been
recorded, or that they are other than what they purport to be on their face. The
Servicer and the Trustee shall keep confidential the name of each Mortgagor
except as required for performance of this Agreement and the Servicer and the
Trustee shall not solicit any such Mortgagor for the purpose of refinancing the
related Mortgage Loan; notwithstanding anything herein to the contrary, the
foregoing shall not be construed to prohibit (i) disclosure of any and all
information that is or becomes publicly known, or information obtained by the
Trustee or the Servicer from sources other than the other parties hereto, (ii)
disclosure of any and all information (A) if required to do so by any applicable
law, rule or regulation, (B) to any government agency or regulatory body having
or claiming authority to regulate or oversee any aspects of the business of the
Trustee, the Servicer or that of any Affiliate, (C) pursuant to any subpoena,
civil investigation demand or similar demand or request of any court, regulatory
authority, arbitrator or arbitration to which the Trustee, the Servicer or any
Affiliate or an officer, director, employer or shareholder thereof is a party or
(D) to any Affiliate, independent or internal auditor, agent, employee or
attorney of the Trustee, or the Servicer having a need to know the same,
provided that the Trustee or the Servicer, as applicable, advises such recipient
of the confidential nature of the information being disclosed, or (iii) any
other disclosure authorized by the Depositor.

     Within 70 days of the Closing Date, the Trustee shall deliver to the NIMs
Insurer, the Depositor and the Servicer the Trustee's Certification,
substantially in the form of Exhibit D attached hereto, evidencing the
completeness of the Mortgage Files, with any exceptions noted thereto.

     SECTION 2.03. Representations, Warranties and Covenants of the Depositor

          (a) The Depositor hereby represents and warrants to the NIMs Insurer,
the Servicer and the Trustee as follows, as of the date hereof:

          (i) The Depositor is duly organized and is validly existing as a
     corporation in good standing under the laws of the State of Delaware and
     has full power and authority (corporate and other) necessary to own or hold
     its properties and to conduct its business as now conducted by it and to
     enter into and perform its obligations under this Agreement and the Sale
     Agreement.

          (ii) The Depositor has the full corporate power and authority to
     execute, deliver and perform, and to enter into and consummate the
     transactions contemplated by, this Agreement and

                                      -65-

<PAGE>

     the Sale Agreement and has duly authorized, by all necessary corporate
     action on its part, the execution, delivery and performance of this
     Agreement and the Sale Agreement; and this Agreement and the Sale
     Agreement, assuming the due authorization, execution and delivery hereof by
     the other parties hereto, constitutes a legal, valid and binding obligation
     of the Depositor, enforceable against the Depositor in accordance with its
     terms, subject, as to enforceability, to (i) bankruptcy, insolvency,
     reorganization, moratorium and other similar laws affecting creditors'
     rights generally and (ii) general principles of equity, regardless of
     whether enforcement is sought in a proceeding in equity or at law.

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

          (iv) No litigation is pending, or, to the best of the Depositor's
     knowledge, threatened, against the Depositor that would materially and
     adversely affect the execution, delivery or enforceability of this
     Agreement and the Sale Agreement or the ability of the Depositor to perform
     its obligations under this Agreement and the Sale Agreement in accordance
     with the terms hereof.

          (v) No consent, approval, authorization or order of any court or
     governmental agency or body is required for the execution, delivery and
     performance by the Depositor of, or compliance by the Depositor with, this
     Agreement and the Sale Agreement or the consummation of the transactions
     contemplated hereby, or if any such consent, approval, authorization or
     order is required, the Depositor has obtained the same. The Depositor
     hereby represents and warrants to the Trustee with respect to each Mortgage
     Loan as of the Closing Date, and following the transfer of the Mortgage
     Loans to it by the Sponsor, the Depositor had good title to the Mortgage
     Loans and the Mortgage Notes were subject to no offsets, claims, liens,
     mortgage, pledge, charge, security interest, defenses or counterclaims.

          (b) The representations and warranties of each Transferor with respect
to the related Mortgage Loans in the applicable Transfer Agreement, which have
been assigned to the Trustee hereunder, were made as of the date specified in
the applicable Transfer Agreement and brought forward to the Closing Date
pursuant to the related Bring Down Letter. The representations and warranties of
each Transferor with respect to the Mortgage Loans contained in the Bring Down
Letter were made as of the Closing Date. The representations and warranties of
the Sponsor with respect to the Mortgage Loans contained in the Sale Agreement
were made as of the Closing Date. To the extent that any fact, condition or
event with respect to a Mortgage Loan constitutes a breach of (i) both
representation or warranty of the applicable Transferor under the applicable
Transfer Agreements or Bring Down Letters and (ii) a representation or warranty
of the Sponsor under the Sale Agreement, the obligations of the Sponsor under

                                      -66-

<PAGE>

the Sale Agreement shall be enforced against the Transferor or the Sponsor, as
applicable, as set forth in the Sale Agreement. The Trustee is hereby directed
to and does acknowledge that the Sponsor shall have no obligation or liability
with respect to any breach of a representation or warranty made by it with
respect to any related Mortgage Loans, except as otherwise set forth in the Sale
Agreement, if (as certified to the Trustee by the Sponsor) the fact, condition
or event constituting such breach also constitutes a breach of a representation
or warranty made by the related Transferor in the related Transfer Agreement or
Bring Down Letter, without regard to whether the related Transferor fulfills its
contractual obligations in respect of such representation or warranty. The
Trustee also is hereby directed to and does acknowledge that the Sponsor shall
have no obligation or liability with respect to any breach of a representation
or warranty made solely by the Transferors with respect to the Mortgage Loans,
without regard to whether the related Transferor fulfills its contractual
obligations in respect of such representation or warranty. The Trustee further
acknowledges that the Depositor shall have no obligation or liability with
respect to any breach of any representation or warranty with respect to the
Mortgage Loans (except as set forth in Section 2.03(a)(iv)) under any
circumstances.

     In addition to the representations and warranties of the Transferors in the
Transfer Agreements that were brought forward to the Closing Date pursuant to
the related Bring Down Letter, with respect to each Mortgage Loan, each
Transferor made certain additional covenants regarding such Mortgage Loan, as
set forth in the related Transfer Agreement. With respect to any breach of such
additional covenants that materially and adversely affects the interests of the
Certificateholders in such Mortgage Loan, the Sponsor shall (1) use reasonable
efforts to enforce such covenant against the related Transferor and (2) if the
Sponsor successfully enforces any obligation of the related Transferor to
repurchase such Mortgage Loan, the Sponsor shall repurchase such Mortgage Loan
in accordance with this Section 2.03. If the Sponsor does not successfully
enforce the obligation, if any, of the Transferor to repurchase a Mortgage Loan
with respect to any breach of any such additional covenants, the Sponsor shall
have no obligation or right to repurchase or cure such Mortgage Loan.

          (c) Upon discovery by any of the NIMs Insurer, the Depositor, the
Servicer or the Trustee of a breach of any of such representations and
warranties that adversely and materially affects the value of the related
Mortgage Loan, Prepayment Charges or the interests of the Certificateholders,
the party discovering such breach shall give prompt written notice to the other
parties. Within 90 days of the discovery of such breach of any representation or
warranty, the applicable Transferor or the Sponsor, as applicable, shall either
(a) cure such breach in all material respects, (b) repurchase such Mortgage Loan
or any property acquired in respect thereof from the Trustee at the Purchase
Price or (c) within the two year period following the Closing Date, substitute a
Replacement Mortgage Loan for the affected Mortgage Loan. In the event of
discovery of a breach of any representation and warranty of any Transferor or
the Sponsor, the Trustee's rights shall be enforced under applicable Transfer
Agreement and the Sale Agreement for the benefit of Certificateholders and the
NIMs Insurer. If a breach of the representations and warranties set forth in a
Transfer Agreement hereof exists solely due to the unenforceability of a
Prepayment Charge, the Trustee (if it has had actual notice thereof) or the
other party having notice thereof shall notify the Servicer thereof and not seek
to enforce the repurchase remedy provided for herein unless such Mortgage Loan
is not current. In the event of a breach of the representations and warranties
with respect to the Mortgage Loans set forth in the Transfer Agreement, the
Trustee shall use reasonable efforts to enforce the right of the Issuing Entity
to be indemnified for such breach of representation and warranty. In the event
that such breach relates solely to the unenforceability of a Prepayment Charge,
amounts received in respect of such indemnity up to the amount of such
Prepayment Charge shall be distributed pursuant to Section 4.04(b)(i). As
provided in the Sale Agreement, if the Sponsor substitutes for a Mortgage Loan
for which there is a breach of any representations and warranties in the related
Transfer Agreement which adversely and materially affects the value of such
Mortgage Loan and such substitute mortgage loan is not a Replacement Mortgage
Loan, under the terms of the Sale Agreement, the

                                      -67-

<PAGE>

Sponsor will, in exchange for such substitute Mortgage Loan, (i) provide the
applicable Purchase Price for the affected Mortgage Loan or (ii) within two
years of the Closing Date, substitute such affected Mortgage Loan with a
Replacement Mortgage Loan. Any such substitution shall not be effected prior to
the additional delivery to the Trustee of a Request for Release substantially in
the form of Exhibit I and shall not be effected unless it is within two years of
the Startup Day. The Sponsor indemnifies and holds the Issuing Entity, the
Trustee, the Depositor, the Servicer, the NIMs Insurer and each
Certificateholder harmless against any and all taxes, claims, losses, penalties,
fines, forfeitures, reasonable legal fees and related costs, judgments, and any
other costs, fees and expenses that the Issuing Entity, the Trustee, the
Depositor, the Servicer, the NIMs Insurer and any Certificateholder may sustain
in connection with any actions of the Sponsor relating to a repurchase of a
Mortgage Loan other than in compliance with the terms of this Section 2.03 and
the Sale Agreement, to the extent that any such action causes (i) any federal or
state tax to be imposed on the Issuing Entity or any REMIC provided for herein,
including without limitation, any federal tax imposed on "prohibited
transactions" under Section 860F(a)(1) of the Code or on "contributions after
the startup day" under Section 860G(d)(1) of the Code, or (ii) any REMIC created
hereunder to fail to qualify as a REMIC at any time that any Certificate is
outstanding. In furtherance of the foregoing, if the Transferor or the Sponsor,
as applicable, is not a member of MERS and repurchases a Mortgage Loan which is
registered on the MERS System, the Transferor or the Sponsor, as applicable, at
its own expense and without any right of reimbursement, shall cause MERS to
execute and deliver an assignment of the Mortgage in recordable form to transfer
the Mortgage from MERS to the Transferor or the Sponsor, as applicable, and
shall cause such Mortgage to be removed from registration on the MERS System in
accordance with MERS' rules and regulations.

     With respect to any Mortgage Loan repurchased by the Sponsor pursuant to
the Sale Agreement, or by any Transferor pursuant to the applicable Transfer
Agreement, the principal portion of the funds received by the Servicer in
respect of such repurchase of a Mortgage Loan will be considered a Principal
Prepayment and shall be deposited in the Collection Account pursuant to Section
3.05. Upon receipt by the Trustee of notice from the Servicer of receipt by the
Servicer of the full amount of the Purchase Price for a Deleted Mortgage Loan,
and upon receipt by the Trustee of the Mortgage File for a Replacement Mortgage
Loan substituted for a Deleted Mortgage Loan and a Request for Release, the
Trustee shall release and reassign to the Sponsor or the applicable Transferor,
as applicable, the related Mortgage File for the Deleted Mortgage Loan and shall
execute and deliver such instruments of transfer or assignment, in each case
without recourse, representation or warranty, as shall be necessary to vest in
such party or its designee or assignee title to any Deleted Mortgage Loan
released pursuant hereto, free and clear of all security interests, liens and
other encumbrances created by this Agreement, which instruments shall be
prepared by the Depositor, the Sponsor or the related Transferor and the Trustee
shall have no further responsibility with respect to the Mortgage File relating
to such Deleted Mortgage Loan.

     With respect to each Replacement Mortgage Loan to be delivered to the
Trustee pursuant to the terms of this Article II in exchange for a Deleted
Mortgage Loan: (i) the applicable Transferor or the Sponsor, as applicable, must
deliver to the Trustee the Mortgage File for the Replacement Mortgage Loan
containing the documents set forth in Section 2.01 along with a written
certification certifying as to the Mortgage Loan satisfying all requirements
under the definition of Replacement Mortgage Loan and the delivery of such
Mortgage File and containing the granting language set forth in Section 2.01;
and (ii) the Depositor will be deemed to have made, with respect to such
Replacement Mortgage Loan, each of the representations and warranties made by it
with respect to the related Deleted Mortgage Loan. The Trustee shall review the
Mortgage File with respect to each Replacement Mortgage Loan and certify to the
Depositor that all documents required by Section 2.01(A)-(B), (C) (if
applicable), and (D)-(E) have been executed and received.

                                      -68-

<PAGE>

     For any month in which the Sponsor substitutes one or more Replacement
Mortgage Loans for one or more Deleted Mortgage Loans, the Sponsor will
determine the amount (if any) by which the aggregate principal balance of all
such Replacement Mortgage Loans as of the date of substitution and the aggregate
Prepayment Charges with respect to such Replacement Mortgage Loans is less than
the aggregate Stated Principal Balance (after application of the principal
portion of the Scheduled Payment due in the month of substitution) and aggregate
Prepayment Charges of all such Deleted Mortgage Loans. An amount equal to the
aggregate of the deficiencies described in the preceding sentence (such amount,
the "Substitution Adjustment Amount") plus an amount equal to any unreimbursed
costs, penalties and/or damages incurred by the Issuing Entity in connection
with any violation relating to such Deleted Mortgage Loan of any predatory or
abusive lending law shall be remitted by the Sponsor to the Trustee for deposit
into the Certificate Account by the Sponsor on the Determination Date for the
Distribution Date relating to the Prepayment Period during which the related
Mortgage Loan became required to be purchased or replaced hereunder.

     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 Replacement Mortgage Loan for a
Deleted Mortgage Loan shall be made unless the Trustee and the NIMs Insurer
shall each 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.

     The Depositor shall amend the Mortgage Loan Schedule to reflect the removal
of such Deleted Mortgage Loan from the terms of this Agreement and the
substitution of the Replacement Mortgage Loan or Replacement Mortgage Loans and
shall deliver a copy of such amended Mortgage Loan Schedule to the NIMs Insurer,
the Servicer and the Trustee. Upon such substitution by the Sponsor, such
Replacement Mortgage Loan or Replacement Mortgage Loans shall constitute part of
the Mortgage Pool and shall be subject in all respects to the terms of this
Agreement and the applicable Sale Agreement, including all applicable
representations and warranties thereof included in the applicable Sale Agreement
as of the date of substitution.

          (d) It is understood and agreed that the representations, warranties
and indemnification (i) set forth in this Section 2.03, (ii) of the Sponsor and
the Depositor set forth in the Sale Agreement and assigned to the Trustee by the
Depositor hereunder and (iii) of each Transferor, assigned by the Sponsor to the
Depositor pursuant to the Sale Agreement and assigned to the Trustee by the
Depositor hereunder shall each survive delivery of the Mortgage Files and the
Assignment of Mortgage of each Mortgage Loan to the Trustee and shall continue
throughout the term of this Agreement.

          (e) The Depositor shall deliver a copy of the Mortgage Loan Schedule
to the Servicer on the Closing Date.

          (f) The Depositor shall notify the Servicer and the Trustee when any
NIM Notes are issued and when such NIM Notes are no longer outstanding.

     SECTION 2.04. Representations and Warranties of the Servicer

     The Servicer hereby represents and warrants to the Depositor and the
Trustee as follows, as of the date hereof:

                                      -69-

          (ii) The Servicer has the corporate power and authority to service

     and consummate the transactions contemplated by this Agreement and has duly
     authorized by all necessary corporate action on the part of the Servicer
     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 a legal, valid and binding obligation
     of the Servicer, enforceable against the Servicer 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 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 the Servicer,
     the servicing of the Mortgage Loans under this Agreement, the consummation
     of any other of the transactions contemplated by this Agreement, and the
     fulfillment of or compliance with the terms hereof are in the ordinary
     course of business of the Servicer and will not (A) result in a material
     breach of any term or provision of the charter or by-laws of the Servicer
     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 the Servicer is a party or
     by which it may be bound, or (C) constitute a material violation of any
     statute, order or regulation applicable to the Servicer of any court,

     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

     Servicer's ability to perform or meet any of its obligations under this
     Agreement.

          (iv) The Servicer is an approved servicer of mortgage loans for Fannie
     Mae and is an approved servicer of mortgage loans for Freddie Mac.

          (v) No litigation is pending or, to the best of the Servicer's

     Agreement or the ability of the Servicer to service the Mortgage Loans or
     to perform any of its other obligations under this Agreement in accordance
     with the terms hereof.

          (vi) No consent, approval, authorization or order of any court or
     governmental agency or body is required for the execution, delivery and
     performance by the Servicer of, or compliance by the Servicer with, this
     Agreement or the consummation of the transactions contemplated hereby, or
     if any such consent, approval, authorization or order is required, the
     Servicer has obtained the same.

                                      -70-

<PAGE>

          (vii) The Servicer will fully furnish (for the period it services the
     Mortgage Loans), in accordance with the Fair Credit Reporting Act and its
     implementing regulations, accurate and complete information (e.g.,
     favorable and unfavorable) on its borrower credit files to Equifax,
     Experian and Trans Union Credit Information Company on a monthly basis.

     SECTION 2.05. Substitutions and Repurchases of Mortgage Loans that are not
"Qualified Mortgages"

     Upon discovery by the Depositor, the Servicer or the Trustee that any
Mortgage Loan does not constitute a "qualified mortgage" within the meaning of
section 860G(a)(3) of the Code, the party discovering such fact shall promptly
(and in any event within five Business Days of discovery) give written notice
thereof to the other parties. In connection therewith, the Depositor shall, at
the Depositor's option, either (i) substitute, if the conditions in Section
2.03(c) with respect to substitutions are satisfied, a Replacement Mortgage Loan
for the affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan
within 90 days of such discovery in the same manner as it would a Mortgage Loan
for a breach of representation or warranty contained in Section 2.03. The
Trustee, upon the written direction of the Depositor, shall reconvey to the
Depositor the Mortgage Loan to be released pursuant hereto in the same manner,
and on the same terms and conditions, as it would a Mortgage Loan repurchased
for breach of a representation or warranty contained in Section 2.03.

     SECTION 2.06. Authentication and Delivery of Certificates

     The Trustee acknowledges the transfer and assignment to it of the Trust
Fund and, concurrently with such transfer and assignment, the Trustee has caused
to be authenticated and delivered to or upon the order of the Depositor, in
exchange for the Mortgage Loans, Certificates duly authenticated by the
Authenticating Agent in authorized denominations evidencing ownership of the
entire Trust Fund. The Trustee agrees to hold the Trust Fund and exercise the
rights referred to above for the benefit of all present and future Holders of
the Certificates and to perform its duties set forth in this Agreement in
accordance with the provisions hereof.

     SECTION 2.07. REMIC Elections

          (a) The Depositor hereby instructs and authorizes the Trustee to make
an appropriate election to treat each of the Upper Tier REMIC, the Lower Tier
REMIC and the SWAP REMIC as a REMIC. The Trustee shall sign the returns
providing for such elections and such other tax or information returns that are
required to be signed by the Trustee under applicable law. This Agreement shall
be construed so as to carry out the intention of the parties that each of the
Upper Tier REMIC, the Lower Tier REMIC and the SWAP REMIC be treated as a REMIC
at all times prior to the date on which the Trust Fund is terminated.

          (b) The Preliminary Statement sets forth the designations and "latest
possible maturity date" for federal income tax purposes of all interests created
hereby. The "Startup Day" for purposes of the REMIC Provisions shall be the
Closing Date. Each REMIC's fiscal year shall be the calendar year.

     The SWAP REMIC shall consist of all of the assets of the Trust Fund, other
than (i) amounts distributable to the Class P Certificates pursuant to Section
4.04(b)(i) hereof, (ii) the interests issued by the SWAP REMIC and the interests
issued by the Lower Tier REMIC, (iii) the grantor trusts described in Section
2.07 hereof, (iv) each Cap Contract and the Cap Contract Account and (v) the
Swap Agreement and the Supplemental Interest Trust. The SWAP REMIC shall issue
the SWAP REMIC Regular Interests, which shall be designated as regular interests
of such REMIC, and shall issue the Class SWR

                                      -71-

<PAGE>

Interest, which shall be designated as the sole class of residual interest in
the SWAP REMIC. Each of the SWAP REMIC Regular Interests shall have the
characteristics set forth in the Preliminary Statement and this Section 2.07.

     The Lower Tier REMIC shall consist of the SWAP REMIC Regular Interests. The
Lower Tier REMIC shall issue the Lower Tier REMIC Regular Interests, which shall
be designated as regular interests of such REMIC and shall issue the Class LTR
Interest, which shall be designated as the sole class of residual interest in
the Lower Tier REMIC. Each of the Lower Tier REMIC Regular Interests shall have
the characteristics set forth in its definition and the Preliminary Statement.

     The assets of the Upper Tier REMIC shall be the Lower Tier REMIC Regular
Interests. The REMIC Regular Interests shall be designated as the regular
interests in the Upper Tier REMIC and the Residual Interest shall be designated
as the sole class of residual interest in the Upper Tier REMIC. For federal
income tax purposes, the pass-through rate on each REMIC Regular Interest (other
than the Uncertificated Class C Interest and the Class UT-IO Interest) and on
the sole class of residual interest in the Upper Tier REMIC shall be subject to
a cap equal to the Upper Tier REMIC Net WAC Cap.

     The beneficial ownership of the Class SWR Interest, Class LTR Interest and
the Residual Interest shall be represented by the Class R Certificate. The Class
SWR Interest and Class LTR Interest shall not have a principal balance or bear
interest.

          (c) The "tax matters person" with respect to each REMIC for purposes
of the REMIC Provisions shall be the beneficial owner of the Class R
Certificate; provided, however, that the Holder of the Class R Certificate, by
its acceptance thereof, irrevocably appoints the Trustee as its agent and
attorney-in-fact to act as "tax matters person" with respect to each such REMIC
for purposes of the REMIC Provisions. If there is more than one beneficial owner
of the Class R Certificate, the "tax matters person" shall be the Person with
the greatest percentage interest in the Class R Certificate and, if there is
more than one such Person, shall be determined under Treasury regulation Section
1.860F-4(d) and Treasury regulation Section 301.6231(a)(7)-1.

          (d) (i) It is intended that the rights of each Class of the Class A,
Class M and Class B Certificates to receive payments in respect of Excess
Interest shall be treated as a right in interest rate cap contracts written by
the Class C Certificateholders in favor of the holders of each Class of the
Class A, Class M and Class B Certificates and such shall be accounted for as
property held separate and apart from the regular interests in the Upper Tier
REMIC held by the holders of the Class A Certificates (other than the Class R
Certificate), Class M Certificates, Class B Certificates and the residual
interest in the Upper Tier REMIC held by the holder of the Class R Certificate.
For information reporting requirements, the rights of the Class A, Class M and
Class B Certificates to receive payments in respect of Excess Interest shall be
assumed to have zero or a de minimis value. This provision is intended to
satisfy the requirements of Treasury Regulations Section 1.860G-2(i) for the
treatment of property rights coupled with REMIC interests to be separately
respected and shall be interpreted consistently with such regulation. On each
Distribution Date, to the extent that any of the Class A, Class M and Class B
Certificates receive payments in respect of Excess Interest, such amounts, to
the extent not derived from payments on the Cap Contracts or the Swap Agreement,
will be treated as distributed by the Upper Tier REMIC to the Class C
Certificates pro rata in payment of the amounts specified in Section 4.04(g) and
then paid to the relevant Class of Certificates pursuant to the related interest
rate cap agreement.

          (ii) It is intended that the beneficial owners of the Certificates
(other than the Class P and Class C Certificates) shall be treated as having
entered into a notional principal contract with respect to the beneficial owners
of the Class C Certificates. Pursuant to each such notional principal contract,
all

                                      -72-

<PAGE>

beneficial owners of each Class of Certificates (other than the Class P and
Class C Certificates) shall be treated as having agreed to pay, on each
Distribution Date, to the beneficial owners of the Class C Certificates an
aggregate amount equal to the excess, if any, of (i) the amount payable on such
Distribution Date on the Corresponding REMIC Regular Interest of such Class of
Certificates over (ii) the amount payable on such Class of Certificates on such
Distribution Date (such excess, a "Class Payment Shortfall"). A Class Payment
Shortfall shall be allocated to each Class of Certificates to the extent that
interest accrued on such Class for the related Accrual Period at the
Pass-Through Rate for a Class, computed by substituting "Upper Tier REMIC Net
WAC Cap" for the Available Funds Cap set forth in the definition thereof,
exceeds the amount of interest accrued on such Certificate at the Pass-Through
Rate (without such substitution) for the related Accrual Period, and a Class
Payment Shortfall payable from principal collections shall be allocated to the
most subordinate Class of Certificates with an outstanding principal balance to
the extent of such balance.

          (e) The parties intend that the portion of the Trust Fund consisting
of the Uncertificated Class C Interest, the uncertificated Class UT-IO Interest,
the rights to receive payments deemed made by the Class A, Class M and Class B
Certificates in respect of notional principal contracts described in Section
2.07(d)(ii), the Supplemental Interest Trust which holds the Swap Agreement, the
Cap Contracts, the Cap Contract Account and the obligation of the holders of the
Class C Certificates to pay amounts in respect of Excess Interest to the holders
of the Class A, Class M and Class B Certificates shall be treated as a "grantor
trust" under the Code, for the benefit of the holders of the Class C
Certificates, and the provisions hereof shall be interpreted consistently with
this intention. In furtherance of such intention, the Trustee shall (i) furnish
or cause to be furnished to the holders of the Class C Certificates information
regarding their allocable share, if any, of the income with respect to such
grantor trust, (ii) file or cause to be filed with the Internal Revenue Service
Form 1041 (together with any necessary attachments) and such other forms as may
be applicable, (iii) comply with such information reporting obligations with
respect to payments from such grantor trust to the holders of Class A, Class M,
Class B and Class C Certificates as may be applicable under the Code and (iv)
provide a properly completed Form W-9 on behalf of such grantor trust to the Cap
Contract Counterpary and Swap Counterparty.

          (f) The parties intend that the portion of the Trust Fund consisting
of the right to receive amounts distributable to the Class P Certificates
pursuant to Section 4.04(b)(i) hereof shall be treated as a "grantor trust"
under the Code, for the benefit of the holders of the Class P Certificates, and
the provisions hereof shall be interpreted consistently with this intention. In
furtherance of such intention, the Trustee shall (i) furnish or cause to be
furnished to the holders of the Class P Certificates information regarding their
allocable share of the income with respect to such grantor trust and (ii) file
or cause to be filed with the Internal Revenue Service Form 1041 (together with
any necessary attachments) and such other forms as may be applicable.

          (g) The parties intend that amounts paid to the Swap Counterparty
under the Swap Agreement shall be deemed for federal income tax purposes to be
paid by the Class C Certificates first, out of funds deemed received in respect
of the Class UT-IO Interest, second, out of funds deemed received in respect of
the Uncertificated Class C Interest and third, out of funds deemed received in
respect of notional principal contracts described in Section 2.07(d)(ii), and
the provisions hereof shall be interpreted consistently with this intention. On
each Distribution Date, to the extent that amounts paid to the Swap Counterparty
are deemed paid out of funds received in respect of the Uncertificated Class C
Interest, such amounts will be treated as distributed by the Upper Tier REMIC to
the Class C Certificates pro rata in payment of the amounts specified in Section
4.04(g) and then paid to the Swap Counterparty pursuant to the Swap Agreement.

                                      -73-
<PAGE>

     The Supplemental Interest Trust shall be an "outside reserve fund" for
federal income tax purposes and not an asset of any REMIC. Furthermore, the
Holders of the Class C Certificates shall be the beneficial owners of the
Supplemental Interest Trust for all federal income tax purposes, and shall be
taxable on all income earned thereon.

          (h) All payments of principal and interest at the Net Mortgage Rate on
each of the Mortgage Loans (other than amounts distributable to the Class P
Certificates pursuant to Section 4.04(b)(i) hereof) received by the SWAP REMIC
with respect to the Mortgage Loans shall be paid to the SWAP REMIC Regular
Interests until the principal balance of all such interests have been reduced to
zero and any losses allocated to such interests have been reimbursed. Any
available funds remaining in the SWAP REMIC on a Distribution Date after
distributions to the SWAP REMIC Regular Interests shall be distributed to the
Class R Certificates on account of the Class SWR Interest. On each Distribution
Date, the Trustee shall distribute the aggregate Interest Funds (net of expenses
and payments to the Class P Certificates) with respect to each of the SWAP REMIC
Regular Interests based on the interest rates for each such SWAP REMIC Regular
Interest. On each Distribution Date, the Trustee shall distribute the aggregate
Principal Funds with respect to the Group One Mortgage Loans first to the Class
1-SW1 Interest until its principal balance is reduced to zero and then
sequentially to each of the other SWAP REMIC Regular Interests beginning with
designation "1" in ascending order of their numerical class designation, in
equal amounts to each such class in such numerical designation, until the
principal balance of each such class is reduced to zero. All losses with respect
to the Group One Mortgage Loans shall be allocated among the SWAP REMIC Regular
Interests beginning with the designation "1" in the same manner that principal
distributions are allocated. On each Distribution Date, the Trustee shall
distribute the aggregate Principal Funds with respect to the Group Two Mortgage
Loans first to the Class 2-SW2 Interest until its principal balance is reduced
to zero and then sequentially to each of the other SWAP REMIC Regular Interests
beginning with designation "2" in ascending order of their numerical class
designation, in equal amounts to each such class in such numerical designation,
until the principal balance of each such class is reduced to zero. All losses
with respect to the Group Two Mortgage Loans shall be allocated among the SWAP
REMIC Regular Interests beginning with the designation "2" in the same manner
that principal distributions are allocated. Subsequent Recoveries with respect
to the Group One and Group Two Mortgage Loans shall be allocated in the reverse
fashion from the manner in which losses are allocated.

     All payments received by the Lower Tier REMIC with respect to the SWAP
REMIC Regular Interests shall be paid to the Lower Tier REMIC Regular Interests
until the principal balance of all such interests have been reduced to zero and
any losses allocated to such interests have been reimbursed. Any excess amounts
shall be distributed to the Class LTR Interest. On each Distribution Date,
payments and losses shall be allocated among the Lower Tier REMIC Regular
Interests so that (i) each of the Lower Tier REMIC I Marker Interests shall have
a principal balance equal to 25% of the principal balance of the Corresponding
Certificates, (ii) the Class LTIX Interest has a principal balance equal to the
excess of (x) 50% of the remaining principal balance of the Mortgage Loans over
(y) the aggregate principal balance of the Lower Tier REMIC I Marker Interests
(if necessary to reflect an increase in overcollateralization, accrued and
unpaid interest on the Class LTIX interest may be added to its principal amount
to achieve this result) and (iii) the aggregate principal amount of the Class
LTII1A Interest, Class LTII1B Interest, Class LTII2A Interest, Class LTII2B
Interest and the Class LTIIX Interest shall equal 50% of the remaining principal
balance of the Mortgage Loans. Distributions and losses allocated to the Lower
Tier REMIC Regular Interests described in clause (iii) of the preceding sentence
will be allocated among such Lower Tier REMIC Regular Interests in the following
manner: (x) such distributions shall be deemed made to such Lower Tier REMIC
Regular Interests first, so as to keep the principal balance of the each such
Lower Tier REMIC Regular Interest with "B" at the end of its designation equal
to 0.05% of the aggregate scheduled principal balance of the Mortgage Loans in
the related Mortgage Group and second,

                                      -74-

<PAGE>

to such Lower Tier REMIC Regular Interests with "A" at the end of its
designation so that the uncertificated principal balance of each such Lower Tier
REMIC Regular Interest is equal to 0.05% of the excess of (I) the aggregate
scheduled principal balance of the Mortgage Loans in the related Mortgage Group
over (II) the aggregate principal balance of Certificate Group One, in the case
of the Class LTII1A Interest, or Certificate Group Two, in the case of the Class
LTII2A Interest (except that if 0.05% of any such excess is greater than the
principal amount of the related Lower Tier REMIC II Marker Interest with "A" at
the end of its designation, the least amount of principal shall be distributed
to each Lower Tier REMIC II Marker Interest with "A" at the end of its
designation such that the Lower Tier REMIC Subordinated Balance Ratio is
maintained) and finally, any remaining distributions of principal to the Class
LTIIX Interest and (y) such losses shall be allocated among the Lower Tier REMIC
Regular Interests described in clause (iii) of the preceding sentence first, so
as to keep the principal balance of the each such Lower Tier REMIC Regular
Interest with "B" at the end of its designation equal to 0.05% of the aggregate
scheduled principal balance of the Mortgage Loans in the related Mortgage Group;
second, to such Lower Tier REMIC Regular Interests with "A" at the end of its
designation so that the uncertificated principal balance of each such Lower Tier
REMIC Regular Interest is equal to 0.05% of the excess of (I) the aggregate
scheduled principal balance of the Mortgage Loans in the related Mortgage Group
over (II) the aggregate principal balance of Certificate Group One, in the case
of the Class LTII1A Interest, or Certificate Group Two, in the case of the Class
LTII2A Interest (except that if 0.05% of any such excess is greater than the
principal amount of the related Lower Tier REMIC II Marker Interest with "A" at
the end of its designation, the least amount of losses shall be allocated to
each Lower REMIC II Marker Interest with "A" at the end of its designation such
that the Lower Tier REMIC Subordinated Balance Ratio is maintained) and finally,
any remaining losses to the Class LTIIX Interest. Notwithstanding the preceding
two sentences, however, losses not allocated to any Class of Certificates will
not be allocated to any Lower Tier REMIC Regular Interests. All computations
with respect to the Lower Tier REMIC Regular Interests shall be taken out to ten
decimal places.

     Any available funds remaining in the Lower Tier REMIC on a Distribution
Date after distributions to the Lower Tier REMIC Regular Interests shall be
distributed to the Class R Certificates in respect of the Class LTR Interest.

     If on any Distribution Date the Certificate Principal Balance of any Class
of Certificates is increased pursuant to the last sentence of the definition of
"Certificate Principal Balance", then there shall be an equivalent increase in
the principal amounts of the Lower Tier REMIC Regular Interests, with such
increase allocated (before the making of distributions and the allocation of
losses on the Lower Tier REMIC Regular Interests on such Distribution Date)
among the Lower Tier REMIC Regular Interests so that, to the greatest extent
possible, (i) each of the Lower Tier REMIC I Marker Interests has a principal
balance equal to 25% of the principal balance of the Corresponding Certificates,
(ii) the Class LTIX Interest has a principal balance equal to the excess of (x)
50% of the remaining principal balance of the Mortgage Loans over (y) the
aggregate principal balance of the Lower Tier REMIC I Marker Interests and (iii)
the aggregate principal amount of the Lower Tier REMIC II Marker Interests and
the Class LTIIX Interest shall equal 50% of the remaining principal balance of
the Mortgage Loans. Allocations in connection with clause (iii) shall be made so
that, to the greatest extent possible, (a) the principal balance of each Lower
Tier REMIC II Marker Interest with "B" at the end of its designation equals
0.05% of the aggregate scheduled principal balance of the Mortgage Loans in
related Mortgage Group, (b) the principal balance of each Lower Tier REMIC II
Marker Interest with "A" at the end of its designation equals 0.05% of the
excess of (x) the aggregate scheduled principal balance of the Mortgage Loans in
related Mortgage Group over (y) the aggregate principal balance of Certificate
Group One in the case of the Class LTII1A Interest, or Certificate Group Two in
the case of the Class LTII2A Interest and (c) any remaining allocations are made
to the Class LTIIX Interest.

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

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

     SECTION 2.08. Covenants of the Servicer

     The Servicer hereby covenants to each of the other parties to this
Agreement that the Servicer shall comply in the performance of its obligations
under this Agreement with all reasonable rules and requirements of the insurer
under each Required Insurance Policy.

     SECTION 2.09. Permitted Activities of the Trust

     The Issuing Entity is created for the object and purpose of engaging in the
Permitted Activities. In furtherance of the foregoing, the Trustee is hereby
authorized and directed to execute and deliver on behalf of the Issuing Entity,
and to perform the duties and obligations of the Issuing Entity under, the Cap
Contracts, an insurance and indemnity agreement with a NIMs Insurer and any
other agreement or instrument related thereto, in each case in such form as the
Depositor shall direct or shall approve, the execution and delivery of any such
agreement by the Depositor to be conclusive evidence of its approval thereof.

     SECTION 2.10. Qualifying Special Purpose Entity

                                      -76-

<PAGE>

     For purposes of SFAS 140, the parties hereto intend that the Issuing Entity
shall be treated as a "qualifying special purpose entity" as such term is used
in SFAS 140 and any successor rule thereto and its power and authority as stated
in Section 2.09 of this Agreement shall be limited in accordance with paragraph
35 or SFAS 140.

     SECTION 2.11. Depositor Notification of NIM Notes

     The Depositor shall notify the Servicer and the Trustee in writing when NIM
Notes are issued and of the identity of the NIMs Insurer, if applicable, and
when all previously issued NIM Notes are no longer outstanding.

                                  ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

     SECTION 3.01. Servicer to Service Mortgage Loans

     For and on behalf of the Certificateholders, the Servicer shall service and
administer the Mortgage Loans in accordance with the Accepted Servicing
Practices. In connection with such servicing and administration, the Servicer
shall have full power and authority, acting alone and/or through subservicers as
provided in Section 3.02 hereof, to do or cause to be done any and all things
that it may deem necessary or desirable in connection with such servicing and
administration, including but not limited to, the power and authority, subject
to the terms hereof (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 (but only
in the manner provided in this Agreement), (iii) to collect any Insurance
Proceeds and other Liquidation Proceeds and (iv) subject to Section 3.12(a), to
effectuate foreclosure or other conversion of the ownership of the Mortgaged
Property securing any Mortgage Loan; provided that, subject to Section 6.03, the
Servicer shall not take any action that is inconsistent with or prejudices the
interests of the Trust Fund or the Certificateholders in any Mortgage Loan
serviced by it under this Agreement or the rights and interests of the other
parties to this Agreement except as otherwise required by this Agreement or by
law. Notwithstanding anything in this Agreement to the contrary, the Servicer
shall not make or permit any modification, waiver or amendment of any term of
any Mortgage Loan which would cause any of the REMICs provided for herein to
fail to qualify as a REMIC or result in the imposition of any tax under Section
860G(a) or 860G(d) of the Code. The Servicer shall represent and protect the
interest of the Trust Fund in the same manner as it currently protects its own
interest in mortgage loans in its own portfolio in any claim, proceeding or
litigation regarding a Mortgage Loan, but in any case not in any manner that is
a lesser standard than that provided in the first sentence of this Section 3.01.
Without limiting the generality of the foregoing, the Servicer, in its own name
or in the name of the Depositor and the Trustee, is hereby authorized and
empowered by the Depositor and the Trustee, when the Servicer believes it
appropriate in its reasonable judgment, to execute and deliver, on behalf of the
Trustee, the Depositor, the Certificateholders or any of them, any and all
instruments of satisfaction or cancellation, or of partial or full release or
discharge, subordinations and all other comparable instruments, with respect to
the Mortgage Loans, and with respect to the Mortgaged Properties held for the
benefit of the Certificateholders. The Servicer shall prepare and deliver to the
Depositor and/or the Trustee such documents requiring execution and delivery by
any or all of them as are necessary or appropriate to enable the Servicer to
service and administer the Mortgage Loans, to the

                                      -77-

<PAGE>

extent that the Servicer is not permitted to execute and deliver such documents
pursuant to the preceding sentence. Upon receipt of such documents, the
Depositor and/or the Trustee shall execute such documents and deliver them to
the Servicer. For purposes of this Section 3.01, the Trustee hereby grants to
the Servicer a limited power of attorney to execute and file any and all
documents necessary to fulfill the obligations of the Servicer under this
Section 3.01.

     Upon request of the Servicer, the Trustee shall furnish the Servicer with
any powers of attorney and other documents in form as provided to it necessary
or appropriate to enable the Servicer to service and administer the Mortgage
Loans. The Trustee shall not be responsible for and the Servicer shall indemnify
the Trustee for any action taken by the Servicer pursuant to the application of
any power of attorney. Notwithstanding anything contained herein to the
contrary, the Servicer shall not without the Trustee's written consent, hire or
procure counsel to represent the Trustee without indicating its representative
capacity.

     The Servicer shall not be required to make any Servicing Advance with
respect to a Mortgage Loan that is 150 days or more delinquent.

     The Servicer and the Trustee shall have at least 30 days' notice of the
appointment of a NIMs Insurer prior to being required to deliver any notices
pursuant to this Agreement to such NIMs Insurer.

     The Servicer and the Trustee shall have at least 10 days' notice of the
issuance of any NIM Notes.

     The Servicer shall deliver a list of Servicing Officers to the Trustee by
the Closing Date.

     The Servicer will transmit full-file credit reporting data for each
Mortgage Loan pursuant to Fannie Mae Guide Announcement 97-02 and for each
Mortgage Loan, the Servicer agrees that it shall report one of the following
statuses each month as follows: current, delinquent (30-, 60-, 90-days, etc.),
foreclosed or charged-off.

     The Servicer further is authorized and empowered by the Trustee, on behalf
of the Certificateholders and the Trustee, in its own name or in the name of the
Sub-Servicer, when the Servicer or the Sub-Servicer, as the case may be,
believes it is appropriate in its best judgment to register any Mortgage Loan on
the MERS System, or cause the removal from the registration of any Mortgage Loan
on the MERS System, to execute and deliver, on behalf of the Trustee and the
Certificateholders or any of them, any and all instruments of assignment and
other comparable instruments with respect to such assignment or re-recording of
a Mortgage in the name of MERS, solely as nominee for the Trustee and its
successors and assigns. Any reasonable expenses incurred in connection with the
actions described in the preceding sentence or as a result of MERS discontinuing
or becoming unable to continue operations in connection with the MERS System,
shall be subject to withdrawal by the Servicer from the Collection Account
(provided that such expenses constitute "unanticipated expenses" within the
meaning of Treasury Regulation Section 1.860G-1(b)(3)(ii)).

     With respect to any Mortgage Loan, the Servicer may consent to the
refinancing of the prior senior lien relating to such Mortgage Loan, provided
that the following requirements are met:

          (a) the resulting Combined Loan-to-Value Ratio of such Mortgage Loan
is no higher than the Combined Loan-to-Value Ratio prior to such refinancing;

          (b) the interest rate for the loan evidencing the refinanced senior
lien is no more than 2.0% higher than the interest rate on the loan evidencing
the existing senior lien immediately prior to the date of such refinancing; and

                                      -78-

<PAGE>

          (c) the loan evidencing the refinanced senior lien is not subject to
negative amortization.

     SECTION 3.02. Servicing and Subservicing; Enforcement of the Obligations of
Servicer

          (a) The Servicer may arrange for the subservicing of any Mortgage Loan
by a subservicer, which may be an affiliate, pursuant to a subservicing
agreement (each, a "Subservicing Agreement"); provided, however, that (i) such
subservicing arrangement and the terms of the related Subservicing Agreement
must provide for the servicing of such Mortgage Loans in a manner consistent
with the servicing arrangements contemplated hereunder, (ii) that such agreement
would not result in a withdrawal or downgrading by any Rating Agency of the
ratings of any Certificates or any of the NIM Notes evidenced by a letter to
that effect delivered by each Rating Agency to the Depositor and the NIMs
Insurer and (iii) the NIMs Insurer shall have consented to such Subservicing
Agreement, which consent shall not be unreasonably withheld. Notwithstanding the
provisions of any Subservicing Agreement, any of the provisions of this
Agreement relating to agreements or arrangements between the Servicer and a
subservicer or reference to actions taken through a subservicer or otherwise,
the Servicer shall remain obligated and liable to the Depositor, the Trustee and
the Certificateholders for the servicing and administration of the Mortgage
Loans in accordance with the provisions of this Agreement without diminution of
such obligation or liability by virtue of such Subservicing Agreements or
arrangements or by virtue of indemnification from the subservicer and to the
same extent and under the same terms and conditions as if the Servicer alone
were servicing and administering the Mortgage Loans. Every Subservicing
Agreement entered into by the Servicer shall contain a provision giving any
successor servicer the option to terminate such agreement, with the consent of
the NIMs Insurer (which consent shall not be unreasonably withheld), in the
event a successor servicer is appointed. All actions of the each subservicer
performed pursuant to the related Subservicing Agreement shall be performed as
an agent of the Servicer with the same force and effect as if performed directly
by the Servicer. The Servicer shall deliver to the NIMs Insurer and the Trustee
copies of all Subservicing Agreements. The Trustee shall have no obligations,
duties or liabilities with respect to a subservicer, including, without
limitation, any obligation, duty or liability to monitor such subservicer or to
pay a subservicer's fees and expenses.

          (b) For purposes of this Agreement, the Servicer shall be deemed to
have received any collections, recoveries or payments with respect to the
related Mortgage Loans that are received by a subservicer regardless of whether
such payments are remitted by the subservicer to the Servicer.

          (c) The Servicer shall not permit a Subservicer to perform any
servicing responsibilities hereunder with respect to the Mortgage Loans unless
that Subservicer first agrees in writing with the Servicer to deliver an
Assessment of Compliance and an Accountant's Attestation in such manner and at
such times that permits that Servicer to comply with Section 3.17 of this
Agreement.

     SECTION 3.03. Rights of the Depositor and the Trustee in Respect of the
Servicer

     Neither the Trustee nor the Depositor shall have any responsibility or
liability for any action or failure to act by the Servicer, and neither of them
is obligated to supervise the performance of the Servicer hereunder or
otherwise.

     SECTION 3.04. Trustee to Act as Servicer

     Subject to Sections 6.04 and 7.02, in the event that the Servicer shall for
any reason no longer be the servicer hereunder (including by reason of an Event
of Default), the Trustee or its designee shall, within a period of time not to
exceed ninety (90) days from the date of notice of termination or resignation,
thereupon assume all of the rights and obligations of the Servicer hereunder
arising thereafter

                                      -79-

<PAGE>

(except that the Trustee shall not be (i) liable for losses arising out of any
acts or omissions of the predecessor servicer hereunder, (ii) obligated to make
Advances or Servicing Advances if it is prohibited from doing so by applicable
law, (iii) obligated to effectuate repurchases or substitutions of Mortgage
Loans hereunder, including pursuant to Section 2.02 or 2.03 hereof, (iv)
responsible for any expenses of the Servicer pursuant to Section 2.03 or (v)
deemed to have made any representations and warranties hereunder, including
pursuant to Section 2.04 or the first paragraph of Section 6.02 hereof;
provided, however that the Trustee (subject to clause (ii) above) or its
designee, in its capacity as the successor servicer, shall immediately assume
the terminated or resigning Servicer's obligation to make Advances and Servicing
Advances). No such termination or resignation shall affect any obligation of the
Servicer to pay amounts owed under this Agreement and to perform its duties
under this Agreement until its successor assumes all of its rights and
obligations hereunder. If the Servicer shall for any reason no longer be a
servicer (including by reason of any Event of Default), the Trustee (or any
other successor servicer) may, at its option, succeed to any rights and
obligations of the Servicer under any subservicing agreement in accordance with
the terms thereof; provided, however, that the Trustee (or any other successor
servicer) shall not incur any liability or have any obligations in its capacity
as servicer under a subservicing agreement arising prior to the date of such
succession unless it expressly elects to succeed to the rights and obligations
of the Servicer thereunder; and the Servicer shall not thereby be relieved of
any liability or obligations under the subservicing agreement arising prior to
the date of such succession. To the extent any costs or expenses, including
without limitation, Servicing Transfer Costs incurred by the Trustee in
connection with this Section 3.04 or Section 7.02, are not paid by the Servicer
pursuant to this Agreement within 30 days of the date of the Trustee's invoice
thereof, such amounts shall be payable out of the Certificate Account; provided
that if the Servicer has been terminated by reason of an Event of Default, the
terminated servicer shall reimburse the Issuing Entity for any such expense
incurred by the Issuing Entity upon receipt of a reasonably detailed invoice
evidencing such expenses. If the Trustee is unwilling or unable to act as
servicer, the Trustee shall seek to appoint a successor servicer that is
eligible in accordance with the criteria specified in this Agreement and
reasonably acceptable to the NIMs Insurer.

     The Servicer shall, upon request of the Trustee, but at the expense of the
Servicer if the Servicer has been terminated by reason of an Event of Default,
deliver to the assuming party all documents and records relating to each
subservicing agreement and the Mortgage Loans then being serviced and otherwise
use its best efforts to effect the orderly and efficient transfer of the
subservicing agreement to the assuming party.

     SECTION 3.05. Collection of Mortgage Loan Payments; Collection Account;
Certificate Account

          (a) The Servicer shall make reasonable efforts in accordance with
Accepted Servicing Practices to collect all payments called for under the terms
and provisions of the Mortgage Loans to the extent such procedures shall be
consistent with this Agreement and the terms and provisions of any related
Required Insurance Policy. Consistent with the foregoing, the Servicer may in
its discretion (i) waive any late payment charge or, if applicable, any default
interest charge, or (ii) subject to Section 3.01, extend the due dates for
payments due on a Mortgage Note for a period not greater than 180 days;
provided, however, that any extension pursuant to clause (ii) above shall not
affect the amortization schedule of any Mortgage Loan for purposes of any
computation hereunder, except as provided below; provided, further, that the
NIMs Insurer's prior written consent shall be required for any modification,
waiver or amendment after the Cut-off Date if the aggregate number of
outstanding Mortgage Loans which have been modified, waived or amended exceeds
5% of the number of Mortgage Loans as of the Cut-Off Date. In the event of any
such arrangement pursuant to clause (ii) above, subject to Section 4.01, the
Servicer shall make any Advances on the related Mortgage Loan during the
scheduled period in accordance with the amortization schedule of such Mortgage
Loan without modification thereof by reason of such arrangements.
Notwithstanding the foregoing, in the event that any Mortgage Loan is in default

                                      -80-

<PAGE>

or, in the judgment of the Servicer, such default is reasonably foreseeable, the
Servicer, consistent with the standards set forth in Section 3.01, may also
waive, modify or vary any term of such Mortgage Loan (including modifications
that would change the Mortgage Rate, forgive the payment of principal or
interest or extend the final maturity date of such Mortgage Loan), accept
payment from the related Mortgagor of an amount less than the Stated Principal
Balance in final satisfaction of such Mortgage Loan, or consent to the
postponement of strict compliance with any such term or otherwise grant
indulgence to any Mortgagor (any and all such waivers, modifications, variances,
forgiveness of principal or interest, postponements, or indulgences collectively
referred to herein as "forbearance"), provided, however, that in determining
which course of action permitted by this sentence it shall pursue, the Servicer
shall adhere to the standards of Section 3.01. The Servicer's analysis
supporting any forbearance and the conclusion that any forbearance meets the
standards of Section 3.01 shall be reflected in writing in the Mortgage File.

          (b) The Servicer will not waive any Prepayment Charge or portion
thereof unless, (i) the enforceability thereof shall have been limited by
bankruptcy, insolvency, moratorium, receivership or other similar laws relating
to creditors' rights generally or is otherwise prohibited by law, or (ii) the
collectability thereof shall have been limited due to acceleration in connection
with a foreclosure or other involuntary payment, or (iii) the Servicer has not
been provided with information sufficient to enable it to collect the Prepayment
Charge, or (iv) in the Servicer's reasonable judgment as described in Section
3.01 hereof, (x) such waiver relates to a default or a reasonably foreseeable
default, (y) such waiver would maximize recovery of total proceeds taking into
account the value of such Prepayment Charge and related Mortgage Loan and (z)
doing so is standard and customary in servicing similar Mortgage Loans
(including any waiver of a Prepayment Charge in connection with a refinancing of
a Mortgage Loan that is related to a default or a reasonably foreseeable
default), or (v) the collection of the Prepayment Charge or of a similar type of
prepayment premium would be considered "predatory" or "illegal" pursuant to
written guidance published by any applicable federal, state or local regulatory
authority having jurisdiction over such matters or has been challenged by any
such authority, or (vi) only to the extent that the Depositor has notified the
Servicer that there are no NIM Notes outstanding, there is a certified class
action in which a similar type of prepayment premium is being challenged. Except
as provided in the preceding sentence, in no event will the Servicer waive a
Prepayment Charge in connection with a refinancing of a Mortgage Loan that is
not related to a default or a reasonably foreseeable default. If the Servicer
waives or does not collect all or a portion of a Prepayment Charge relating to a
Principal Prepayment in full or in part due to any action or omission of the
Servicer, other than as provided above, the Servicer shall deposit the amount of
such Prepayment Charge (or such portion thereof as had been waived for deposit)
into the Collection Account for distribution in accordance with the terms of
this Agreement.

          (c) The Servicer shall not be required to institute or join in
litigation with respect to collection of any payment (whether under a Mortgage,
Mortgage Note or otherwise or against any public or governmental authority with
respect to a taking or condemnation) if it reasonably believes that enforcing
the provision of the Mortgage or other instrument pursuant to which such payment
is required is prohibited by applicable law.

          (d) The Servicer shall establish and initially maintain, on behalf of
the Certificateholders, a Collection Account. The Servicer shall deposit into
such Collection Account daily, within two Business Days of receipt thereof, in
immediately available funds, the following payments and collections received or
made by it on and after the Cut-off Date with respect to the Mortgage Loans:

          (i) all payments on account of principal, including Principal
     Prepayments, on the Mortgage Loans, other than principal due on the
     Mortgage Loans on or prior to the Cut-off Date;

                                      -81-

<PAGE>

          (ii) all payments on account of interest on the Mortgage Loans net of
     the Servicing Fee permitted under Section 3.15, other than (x) interest due
     on the Mortgage Loans on or prior to the Cut-off Date and (y) Prepayment
     Interest Excess;

          (iii) all Liquidation Proceeds, other than proceeds to be applied to
     the restoration or repair of the Mortgaged Property or released to the
     Mortgagor in accordance with the Servicer's normal servicing procedures;

          (iv) all Subsequent Recoveries;

          (v) all Compensating Interest;

          (vi) any amount required to be deposited by the Servicer pursuant to
     Section 3.05(g) in connection with any losses on Permitted Investments;

          (vii) any amounts required to be deposited by the Servicer pursuant to
     Section 3.10 hereof;

          (viii) all Advances made by the Servicer pursuant to Section 4.01;

          (ix) all Prepayment Charges; and

          (x) any other amounts required to be deposited hereunder.

     The foregoing requirements for remittance by the Servicer into the
Collection Account shall be exclusive, it being understood and agreed that,
without limiting the generality of the foregoing, late payment charges,
insufficient funds charges and payments in the nature of assumption fees (i.e.
fees related to the assumption of a Mortgage Loan upon the purchase of the
related Mortgaged Property and other similar ancillary fees (other than
Prepayment Charges) if collected, and any Prepayment Interest Excess) need not
be remitted by the Servicer. Rather, such fees and charges may be retained by
the Servicer as additional servicing compensation. In the event that the
Servicer shall remit any amount not required to be remitted and not otherwise
subject to withdrawal pursuant to Section 3.08 hereof, it may at any time
withdraw or direct the Trustee, or such other institution maintaining the
Collection Account, to withdraw such amount from the Collection Account, any
provision herein to the contrary notwithstanding. The Servicer shall maintain
adequate records with respect to all withdrawals made pursuant to this Section.
All funds deposited in the Collection Account shall be held in trust for the
Certificateholders until withdrawn in accordance with Section 3.08. In no event
shall the Trustee incur liability for withdrawals from the Collection Account at
the direction of the Servicer.

     The Servicer shall give notice to the NIMs Insurer and the Trustee of the
location of the Collection Account maintained by it when established and prior
to any change thereof. Not later than twenty days after each Distribution Date,
the Servicer shall forward to the NIMs Insurer, the Trustee and the Depositor
the most current available bank statement for the Collection Account. Copies of
such statement shall be provided by the Trustee to any Certificateholder and to
any Person identified to the Trustee as a prospective transferee of a
Certificate, upon request at the expense of the requesting party, provided such
statement is delivered by the Servicer to the Trustee.

          (e) The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Certificate Account. The Trustee shall, promptly upon
receipt, deposit or cause to be deposited in the Certificate Account and retain
therein the following:

                                      -82-

<PAGE>

          (i) the aggregate amount withdrawn by the Servicer from the Collection
     Account for deposit in the Certificate Account;

          (ii) the Purchase Price and any Substitution Adjustment Amount;

          (iii) any amount required to be deposited by the Trustee pursuant to
     Section 3.05(g) in connection with any losses on Permitted Investments; and

          (iv) the Optional Termination Amount paid by the winning bidder at the
     Auction or by the Servicer pursuant to Section 9.01.

     Any amounts received by the Trustee prior to 4:00 p.m. New York City time
(or such earlier deadline for investment in the Permitted Investments designated
by the Trustee) which are required to be deposited in the Certificate Account by
the Servicer may be invested for the benefit of the Trustee in Permitted
Investments on the Business Day on which they were received. The foregoing
requirements for remittance by the Servicer and deposit by the Servicer into the
Certificate Account shall be exclusive. If the Servicer fails to remit any funds
due by the time designated herein, the Servicer shall pay to the Trustee, for
its own account, interest accrued on such funds at the prime rate as set forth
in The Wall Street Journal from and including the applicable due date, to but
excluding the day such funds are paid to the Trustee. In the event that the
Servicer shall remit any amount not required to be remitted and not otherwise
subject to withdrawal pursuant to Section 3.08 hereof, it may at any time
withdraw such amount from the Certificate Account, any provision herein to the
contrary notwithstanding. All funds deposited in the Certificate Account shall
be held by the Trustee in trust for the Certificateholders until disbursed in
accordance with this Agreement or withdrawn in accordance with Section 3.08. In
no event shall the Trustee incur liability for withdrawals from the Certificate
Account at the direction of the Servicer. The Trustee shall give notice to the
NIMs Insurer and the Servicer of the location of the Certificate Account
maintained by it when established and prior to any change thereof.

          (f) Each institution that maintains the Collection Account shall, and
each institution that maintains the Certificate Account may but shall not be
required to, invest the funds in each such account, as directed by the Servicer
or the Trustee, as applicable, in writing, in Permitted Investments, which shall
mature not later than (i) in the case of the Collection Account, the Business
Day preceding the Servicer Remittance Date (except that if such Permitted
Investment is an obligation of the institution that maintains such Collection
Account or is otherwise immediately available, then such Permitted Investment
shall mature not later than the Servicer Remittance Date) and (ii) in the case
of the Certificate Account, the Business Day immediately preceding the first
Distribution Date that follows the date of such investment (except that if such
Permitted Investment is an obligation of the institution that maintains such
Certificate Account or is otherwise immediately available, then such Permitted
Investment shall mature not later than such Distribution Date) and, in each
case, shall not be sold or disposed of prior to its maturity. All such Permitted
Investments shall be made in the name of the Trustee for the benefit of the
Certificateholders. All income and gain net of any losses realized from amounts
on deposit in the Collection Account shall be for the benefit of the Servicer as
servicing compensation and shall be remitted to it monthly as provided herein.
The amount of any losses incurred in the Collection Account in respect of any
such investments shall be deposited by the Servicer in the Collection Account
out of the Servicer's own funds immediately as realized. All income and gain net
of any losses realized from amounts on deposit in the Certificate Account shall
be for the benefit of the Trustee and shall be remitted to or withdrawn by it
monthly as provided herein. The amount of any losses incurred in the Certificate
Account in respect of any such investments shall be deposited by the Trustee in
the Certificate Account out of the Trustee's own funds immediately as realized.

     SECTION 3.06. Collection of Taxes, Assessments and Similar Items; Escrow
Accounts

     To the extent required by the related Mortgage Note, the Servicer shall
establish and maintain one or more accounts (each, an "Escrow Account") and
deposit and retain therein all collections from the Mortgagors (or advances by
the Servicer) for the payment of taxes, assessments, hazard insurance premiums
or comparable items for the account of the Mortgagors. Nothing herein shall
require the Servicer to compel a Mortgagor to establish an Escrow Account in
violation of applicable law.

     Withdrawals of amounts so collected from the Escrow Accounts may be made
only to effect timely payment of taxes, assessments, hazard insurance premiums,
condominium or PUD association dues, or comparable items, to reimburse the
Servicer out of related collections for any payments made pursuant to Sections
3.01 hereof (with respect to taxes and assessments and insurance premiums) and
3.10 hereof (with respect to hazard insurance), to refund to any Mortgagors any
sums as may be determined to be overages, to pay interest, if required by law or
the terms of the related Mortgage or Mortgage Note, to Mortgagors on balances in
the Escrow Account or to clear and terminate the Escrow Account at the
termination of this Agreement in accordance with Section 9.01 hereof. The Escrow
Accounts shall not be a part of the Trust Fund.

     SECTION 3.07. Access to Certain Documentation and Information Regarding the
Mortgage Loans

     Upon reasonable advance notice in writing if required by federal
regulation, the Servicer will provide to each Certificateholder that is a
savings and loan association, bank or insurance company certain reports and
reasonable access to information and documentation regarding the Mortgage Loans
sufficient to permit such Certificateholder to comply with applicable
regulations of the OTS or other regulatory authorities with respect to
investment in the Certificates; provided, that the Servicer shall be entitled to
be reimbursed by each such Certificateholder for actual expenses incurred by the
Servicer in providing such reports and access.

     The Servicer may from time to time provide the Depositor, and any Person
designated by the Depositor, with reports and information regarding the Mortgage
Loans, including without limitation, information requested by the Depositor or
an originator of the Mortgage Loans for required institutional risk control. In
addition, subject to limitations of applicable privacy laws, the Servicer may
make public information regarding performance of the Mortgage Loans.

     In addition, with respect to each MI Mortgage Loan that is subject to a
modification, the Servicer shall provide the MI Insurer with written notice of
such modification, which shall include the nature of such modification.

     SECTION 3.08. Permitted Withdrawals from the Collection Account and
Certificate Account

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

          (i) to pay to the Servicer (to the extent not previously paid to or
     withheld by the Servicer), as servicing compensation in accordance with
     Section 3.15, that portion of any payment of interest that equals the
     Servicing Fee for the period with respect to which such interest payment
     was made, and, as additional servicing compensation, those other amounts
     set forth in Section 3.15;

                                      -84-

<PAGE>

          (ii) to reimburse the Servicer (or the Trustee as successor servicer)
     for Advances made by it (or to reimburse the advance financing person for
     Advances made by it) with respect to the Mortgage Loans, such right of
     reimbursement pursuant to this subclause (ii) being limited to amounts
     received on particular Mortgage Loan(s) (including, for this purpose,
     Liquidation Proceeds) that represent late recoveries of payments of
     principal and/or interest on such particular Mortgage Loan(s) in respect of
     which any such Advance was made;

          (iii) to reimburse the Servicer for any Non-Recoverable Advance
     previously made and any MI Insurer Fees, Non-Recoverable Servicing Advances
     previously made to the extent that, in the case of Non-Recoverable
     Servicing Advances, reimbursement therefor constitutes "unanticipated
     expenses" within the meaning of Treasury Regulation Section
     1.860G-1(b)(3)(ii);

          (iv) to pay to the Servicer earnings on or investment income with
     respect to funds in or credited to the Collection Account;

          (v) to reimburse the Servicer from Insurance Proceeds for Insured
     Expenses covered by the related Insurance Policy;

          (vi) [reserved];

          (vii) to pay the Servicer (or the Trustee as successor servicer) any
     unpaid Servicing Fees and to reimburse it for any unreimbursed Servicing
     Advances (to the extent that reimbursement for Servicing Advances would
     constitute an "unanticipated expense" within the meaning of Treasury
     Regulation Section 1.860G-1(b)(3)(ii)), the Servicer's right to
     reimbursement of Servicing Advances pursuant to this subclause (vii) with
     respect to any Mortgage Loan being limited to amounts received on
     particular Mortgage Loan(s)(including, for this purpose, Liquidation
     Proceeds and purchase and repurchase proceeds) that represent late
     recoveries of the payments for which such advances were made pursuant to
     Section 3.01 or Section 3.06;

          (viii) to pay to the Depositor or the Servicer, as applicable, with
     respect to each Mortgage Loan or property acquired in respect thereof that
     has been purchased pursuant to Section 2.02, 2.03 or 3.12, all amounts
     received thereon and not taken into account in determining the related
     Stated Principal Balance of such repurchased Mortgage Loan;

          (ix) to reimburse the Servicer, the Trustee or the Depositor for
     expenses incurred by any of them in connection with the Mortgage Loans or
     Certificates and reimbursable pursuant to Section 3.04, Section 3.25 or
     Section 6.03 hereof provided that reimbursement therefor would constitute
     "unanticipated" expenses within the meaning of Treasury Regulation Section
     1.860G-1(b)(3)(ii);

          (x) to reimburse the Trustee for expenses reasonably incurred in
     respect of a breach or defect giving rise to the purchase obligation in
     Section 2.03 that were incurred in the Purchase Price of the Mortgage Loans
     including any expenses arising out of the enforcement of the purchase
     obligation; provided that any such expenses will be reimbursable under this
     subclause (x) only to the extent that such expenses would constitute
     "unanticipated expenses" within the meaning of Treasury Regulation Section
     1.860G-1(b)(3)(ii) if paid by one of the REMICs provided for herein;

          (xi) to pay the Servicer any unpaid Servicing Fees for any Mortgage
     Loan upon such Mortgage Loan being charged off and upon termination of the
     obligations of the Servicer;

                                      -85-

<PAGE>

          (xii) to withdraw pursuant to Section 3.05 any amount deposited in the
     Collection Account and not required to be deposited therein;

          (xiii) to clear and terminate the Collection Account upon termination
     of this Agreement pursuant to Section 9.01 hereof; and

          (xiv) to pay the MI Insurer, the MI Insurer Fee.

     In addition, the Servicer will use commercially reasonable efforts to cause
to be withdrawn from the Collection Account no later than 12:00 p.m. New York
City time, but in any case no later than 2:00 p.m. New York City time on the
Servicer Remittance Date, the Interest Funds and the Principal Funds (for this
purpose only, neither Interest Funds nor Principal Funds shall include a
deduction for any amount reimbursable to the Trustee unless such amounts have
actually been reimbursed from such funds at the discretion of the Servicer), to
the extent on deposit, and such amount shall be deposited in the Certificate
Account; provided, however, if the Trustee does not receive such Interest Funds
and Principal Funds by 2:00 p.m. on the Servicer Remittance Date, the Servicer
shall pay, out of its own funds, interest on such amount at a rate equal to the
"prime rate" as published by The Wall Street Journal at such time for each date
or part thereof.

     In addition, on each Servicer Remittance Date, the Servicer shall withdraw
an amount equal to the MI Insurer Fee and pay such amount to the MI Insurer but
only to the extent the Servicer has received the MI Insurer Invoice setting
forth such amount. The Servicer shall be entitled to rely conclusively upon the
information set forth in the MI Insurer Invoice.

     The Servicer shall keep and maintain separate accounting, on a Mortgage
Loan by Mortgage Loan basis, for the purpose of justifying any withdrawal from
the Collection Account.

     The Servicer shall provide written notification to the Trustee on or prior
to the next succeeding Servicer Remittance Date upon making any withdrawals from
the Collection Account pursuant to subclauses (iii) and (vii) above.

     Unless otherwise specified, any amounts reimbursable to the Servicer or the
Trustee from amounts on deposit in the Collection Account or the Certificate
Accounts shall be deemed to come from first, Interest Funds, and thereafter,
Principal Funds for the related Distribution Date.

          (b) The Trustee shall withdraw funds from the Certificate Account for
distribution to the Certificateholders in the manner specified in this Agreement
(and shall withhold from the amounts so withdrawn, the amount of any taxes that
it is authorized to retain pursuant to this Agreement). In addition, prior to
making such distributions to the Certificateholders, the Trustee may from time
to time make withdrawals from the Certificate Account for the following
purposes:

          (i) to withdraw pursuant to Section 3.05 any amount deposited in the
     Certificate Account and not required to be deposited therein;

          (ii) to clear and terminate the Certificate Account upon termination
     of the Agreement pursuant to Section 9.01 hereof (after paying all amounts
     necessary to the Trustee or the Servicer in connection with any such
     termination);

          (iii) to pay to the Trustee for any fees, expenses and indemnification
     reimbursable pursuant to this Agreement, including without limitation
     Sections 3.04, 6.03, 8.05 and 8.06 hereof; and

                                      -86-

<PAGE>

          (iv) to pay to the Trustee earnings on or investment income with
     respect to funds in or credited to the Certificate Account.

     SECTION 3.09. [RESERVED]

     SECTION 3.10. Maintenance of Hazard Insurance

     The Servicer shall cause to be maintained, for each first lien Mortgage
Loan, hazard insurance with extended coverage in an amount, to the extent
permitted by applicable law, that is at least equal to the lesser of (i) the
estimated replacement value of the improvements that are part of such Mortgaged
Property which may be the last known coverage, and (ii) the greater of (a) the
outstanding principal balance of the Mortgage Loan and (b) an amount such that
the proceeds of such policy shall be sufficient to prevent the related Mortgagor
and/or mortgagee from becoming a co-insurer. Each such policy of standard hazard
insurance shall contain, or have an accompanying endorsement that contains, a
standard mortgagee clause. The Servicer shall also cause flood insurance to be
maintained on property acquired upon foreclosure or deed in lieu of foreclosure
of any Mortgage Loan, to the extent required under the standards described
below. Pursuant to Section 3.05 hereof, any amounts collected by the Servicer
under any such policies (other than the amounts to be applied to the restoration
or repair of the related Mortgaged Property or property thus acquired or amounts
released to the Mortgagor in accordance with the Servicer's normal servicing
procedures) shall be deposited in the Collection Account. Any cost incurred by
the Servicer in maintaining any such insurance shall not, for the purpose of
calculating monthly distributions to the Certificateholders or remittances to
the Trustee for their benefit, be added to the principal balance of the Mortgage
Loan, notwithstanding that the terms of the Mortgage Loan so permit. Such costs
shall be recoverable by the Servicer out of late payments by the related
Mortgagor or out of Liquidation Proceeds to the extent and as otherwise
permitted by Section 3.08 hereof. It is understood and agreed that no earthquake
or other additional insurance is to be required of any Mortgagor or maintained
on property acquired in respect of a Mortgage other than pursuant to such
applicable laws and regulations as shall at any time be in force and as shall
require such additional insurance. If a first lien Mortgaged Property is located
at the time of origination of the Mortgage Loan in a federally designated
special flood hazard area and such area is participating in the national flood
insurance program, the Servicer shall cause flood insurance to be maintained
with respect to such Mortgage Loan. Such flood insurance shall be in an amount
equal to the lesser of (i) the outstanding principal balance of the related
Mortgage Loan, (ii) the estimated replacement value of the improvements that are
part of such Mortgaged Property which may be the last known coverage, or (iii)
the maximum amount of such insurance available for the related Mortgaged
Property under the Flood Disaster Protection Act of 1973, as amended.

     In the event that the Servicer shall obtain and maintain a blanket policy
insuring against hazard losses on all of the Mortgage Loans, it shall
conclusively be deemed to have satisfied its obligations as set forth in the
first sentence of this Section 3.10, it being understood and agreed that such
policy may contain a deductible clause on terms substantially equivalent to
those commercially available and maintained by comparable servicers. If such
policy contains a deductible clause, the Servicer shall, in the event that there
shall not have been maintained on the related Mortgaged Property a policy
complying with the first sentence of this Section 3.10, and there shall have
been a loss that would have been covered by such policy, deposit in the
Collection Account the amount not otherwise payable under the blanket policy
because of such deductible clause. In connection with its activities as servicer
of the Mortgage Loans, the Servicer agrees to present, on behalf of itself, the
Depositor and the Trustee for the benefit of the Certificateholders, claims
under any such blanket policy.

     SECTION 3.11. Enforcement of Due-On-Sale Clauses; Assumption Agreements

                                      -87-

<PAGE>

     When a Mortgaged Property has been or is about to be conveyed by the
Mortgagor, the Servicer shall, except as set forth below, to the extent it has
knowledge of such conveyance or prospective conveyance, exercise its rights to
accelerate the maturity of the related Mortgage Loan under any "due-on-sale"
clause contained in the related Mortgage or Mortgage Note; provided, however,
that the Servicer shall not exercise any such right if the "due-on-sale" clause,
in the reasonable belief of the Servicer, is not enforceable under applicable
law; provided, further, that the Servicer shall not take any action in relation
to the enforcement of any "due-on-sale" clause that would adversely affect or
jeopardize coverage under any Required Insurance Policy. An Opinion of Counsel
at the expense of the Servicer (which expense shall constitute a Servicing
Advance) delivered to the Trustee and the Depositor shall conclusively establish
the reasonableness of the Servicer's belief that any "due-on-sale" clause is not
enforceable under applicable law. In such event, the Servicer shall make
reasonable efforts to enter into an assumption and modification agreement with
the Person to whom such property has been or is about to be conveyed, pursuant
to which such Person becomes liable under the Mortgage Note and, unless
prohibited by applicable law or the Mortgage, the Mortgagor remains liable
thereon. If the foregoing is not permitted under applicable law, the Servicer is
authorized to enter into a substitution of liability agreement with such Person,
pursuant to which the original Mortgagor is released from liability and such
Person is substituted as Mortgagor and becomes liable under the Note. In
addition to the foregoing, the Servicer shall not be required to enforce any
"due-on-sale" clause if in the reasonable judgment of the Servicer, entering
into an assumption and modification agreement with a Person to whom such
property shall be conveyed and releasing the original Mortgagor from liability
would be in the best interests of the Certificateholders. The Mortgage Loan, as
assumed, shall conform in all respects to the requirements, representations and
warranties of this Agreement. The Servicer shall notify the Trustee that any
such assumption or substitution agreement has been completed by forwarding to
the Trustee the original copy of such assumption or substitution agreement
(indicating the Mortgage File to which it relates), which copy shall be added by
the Trustee to the related Mortgage File and which shall, for all purposes, be
considered a part of such Mortgage File to the same extent as all other
documents and instruments constituting a part thereof. The Servicer shall be
responsible for recording any such assumption or substitution agreements. In
connection with any such assumption or substitution agreement, the Monthly
Payment on the related Mortgage Loan shall not be changed but shall remain as in
effect immediately prior to the assumption or substitution, the stated maturity
or outstanding principal amount of such Mortgage Loan shall not be changed nor
shall any required monthly payments of principal or interest be deferred or
forgiven. Any fee collected by the Servicer for consenting to any such
conveyance or entering into an assumption or substitution agreement shall be
retained by or paid to the Servicer as additional servicing compensation.

     Notwithstanding the foregoing paragraph or any other provision of this
Agreement, the Servicer shall not be deemed to be in default, breach or any
other violation of its obligations hereunder by reason of any assumption of a
Mortgage Loan by operation of law or any assumption which the Servicer may be
restricted by law from preventing, for any reason whatsoever.

     SECTION 3.12. Realization Upon Defaulted Mortgage Loans; Determination of
Excess Proceeds; Special Loss Mitigation

          (a) The Servicer shall use reasonable efforts consistent with the
servicing standard set forth in Section 3.01 to foreclose upon or otherwise
comparably convert the ownership of 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. In connection
with such foreclosure or other conversion, the Servicer shall follow such
practices and procedures as it shall deem necessary or advisable and as shall be
normal and usual in its general mortgage servicing activities and the
requirements of the insurer under any Required Insurance Policy; provided,
however, that the Servicer

                                      -88-

<PAGE>

shall not be required to expend its own funds in connection with the restoration
of any property that shall have suffered damage due to an uninsured cause unless
it shall determine (i) that such restoration will increase the proceeds of
liquidation of the Mortgage Loan after reimbursement to itself of such expenses
and (ii) that such expenses will be recoverable to it through Liquidation
Proceeds (respecting which it shall have priority for purposes of withdrawals
from the Collection Account pursuant to Section 3.08 hereof). The Servicer shall
be responsible for all other costs and expenses incurred by it in any such
proceedings; provided, however, that it shall be entitled to reimbursement
thereof from the proceeds of liquidation of the related Mortgaged Property, as
contemplated in Section 3.08 hereof. If the Servicer receives written notice
that a Mortgaged Property that it is contemplating acquiring in foreclosure or
by deed-in-lieu of foreclosure is located within a one-mile radius of any site
with environmental or hazardous waste risks known to the Servicer, the Servicer
will, prior to acquiring the Mortgaged Property, consider such risks and only
take action in accordance with Accepted Servicing Practices.

     With respect to any REO Property, the deed or certificate of sale shall be
taken in the name of the Trustee or its nominee. Pursuant to its efforts to sell
such REO Property, the Servicer shall either itself or through an agent selected
by the Servicer protect and conserve such REO Property in the same manner and to
such extent as is customary in the locality where such REO Property is located
and may, incident to its conservation and protection of the interests of the
Certificateholders, rent the same, or any part thereof, as the Servicer deems to
be in the best interest of itself and the Certificateholders for the period
prior to the sale of such REO Property. The Servicer or an Affiliate thereof may
receive usual and customary real estate referral fees for real estate brokers in
connection with the listing and disposition of REO Property. The Servicer shall
prepare a statement with respect to each REO Property that has been rented
showing the aggregate rental income received and all expenses incurred in
connection with the management and maintenance of such REO Property at such
times as is necessary to enable the Servicer to comply with the reporting
requirements of the REMIC Provisions. The net monthly rental income, if any,
from such REO Property shall be deposited in the Collection Account no later
than the close of business on each Determination Date. The Servicer shall
perform the tax reporting and withholding related to foreclosures, abandonments
and cancellation of indebtedness income as specified by Sections 1445, 6050J and
6050P of the Code by preparing and filing such tax and information returns, as
may be required.

     In the event that the Issuing Entity acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Servicer shall dispose of such Mortgaged Property prior to
the expiration of three years from the end of the year of its acquisition by the
Issuing Entity or, at the expense of the Issuing Entity, obtain, in accordance
with applicable procedures for obtaining an automatic extension of the grace
period, more than 60 days prior to the day on which such three-year period would
otherwise expire, an extension of the three-year grace period, in which case
such property must be disposed of prior to the end of such extension, unless the
Trustee and the NIMs Insurer shall have been supplied with an Opinion of Counsel
(such Opinion of Counsel not to be an expense of the Trustee or the NIMs
Insurer), to the effect that the holding by the Issuing Entity of such Mortgaged
Property subsequent to such three-year period or extension will not result in
the imposition of taxes on "prohibited transactions" of the Issuing Entity or
any of the REMICs provided for herein as defined in section 860F of the Code or
cause any of the REMICs provided for herein to fail to qualify as a REMIC at any
time that any Certificates are outstanding, in which case the Issuing Entity may
continue to hold such Mortgaged Property (subject to any conditions contained in
such Opinion of Counsel). Notwithstanding any other provision of this Agreement,
no Mortgaged Property acquired by the Issuing Entity shall be held, rented (or
allowed to continue to be rented) or otherwise used for the production of income
by or on behalf of the Issuing Entity in such a manner or pursuant to any terms
that would (i) cause such Mortgaged Property to fail to qualify as "foreclosure
property" within the meaning of section 860G(a)(8) of the Code or (ii) subject
the Issuing Entity or any REMIC provided for herein to the

                                      -89-

<PAGE>

imposition of any federal, state or local income taxes on the income earned from
such Mortgaged Property under section 860G(c) of the Code or otherwise, unless
the Servicer or the Depositor has agreed to indemnify and hold harmless the
Trustee and the Trust Fund with respect to the imposition of any such taxes.

     The decision of the Servicer to foreclose on a defaulted Mortgage Loan
shall be subject to a determination by the Servicer that the proceeds of such
foreclosure would exceed the costs and expenses of bringing such a proceeding.
The income earned from the management of any Mortgaged Properties acquired
through foreclosure or other judicial proceeding, net of reimbursement to the
Servicer for expenses incurred (including any property or other taxes) in
connection with such management and net of unreimbursed Servicing Fees,
Advances, Servicing Advances and any management fee paid or to be paid with
respect to the management of such Mortgaged Property, shall be applied to the
payment of principal of, and interest on, the related defaulted Mortgage Loans
(with interest accruing as though such Mortgage Loans were still current) and
all such income shall be deemed, for all purposes in this Agreement, to be
payments on account of principal and interest on the related Mortgage Notes and
shall be deposited into the Collection Account. To the extent the income
received during a Prepayment Period is in excess of the amount attributable to
amortizing principal and accrued interest at the related Mortgage Rate on the
related Mortgage Loan, such excess shall be considered to be a partial Principal
Prepayment for all purposes hereof.

     The Liquidation Proceeds from any liquidation of a Mortgage Loan, net of
any payment to the Servicer as provided above, shall be deposited in the
Collection Account on the next succeeding Determination Date following receipt
thereof for distribution on the related Distribution Date.

     The proceeds of any Liquidated Loan, as well as any recovery resulting from
a partial collection of Liquidation Proceeds, will be applied as between the
parties in the following order of priority: first, to reimburse the Servicer for
any related unreimbursed Servicing Advances and unpaid Servicing Fees, pursuant
to Section 3.08(a)(vi) or this Section 3.12; second, to reimburse the Servicer
for any unreimbursed Advances, pursuant to Section 3.08(a)(ii) or this Section
3.12; third, to accrued and unpaid interest (to the extent no Advance has been
made for such amount) on the Mortgage Loan, at the Net Mortgage Rate to the Due
Date occurring in the month in which such amounts are required to be
distributed; fourth, as a recovery of principal of the Mortgage Loan; and fifth,
to any prepayment charges.

     The proceeds of any net income from an REO Property will be applied as
between the parties in the following order of priority: first, to reimburse the
Servicer for any related unreimbursed Servicing Advances and unpaid Servicing
Fees, pursuant to Section 3.08(a)(vi) or this Section 3.12; second, to reimburse
the Servicer for any unreimbursed Advances, pursuant to Section 3.08(a)(ii) or
this Section 3.12; third, as a recovery of principal; and fourth, to accrued and
unpaid interest (to the extent no Advance has been made for such amount) on the
related REO Property, at the applicable Net Mortgage Rate to the Due Date
occurring in the month in which such amounts are required to be distributed.

          (b) On each Determination Date, the Servicer shall determine the
respective aggregate amounts of Excess Proceeds, if any, that occurred in the
related Prepayment Period.

          (c) [RESERVED]

          (d) With respect to such of the Mortgage Loans as come into and
continue in default, the Servicer will decide, in its reasonable business
judgment, whether to (i) foreclose upon the Mortgaged Properties securing those
Mortgage Loans pursuant to Section 3.12(a), (ii) write off the unpaid principal
balance of the Mortgage Loans as bad debt (provided that the Servicer has
determined that no net recovery is possible through foreclosure proceedings or
other liquidation of the related Mortgaged

                                      -90-

<PAGE>

Property), (iii) take a deed in lieu of foreclosure, (iv) accept a short sale or
short refinance; (v) arrange for a repayment plan or refinancing, or (vi) agree
to a modification of such Mortgage Loan. As to any Mortgage Loan that becomes
120 days delinquent, the Servicer shall have obtained or shall obtain a broker's
price opinion, the cost of which will be reimbursable as a Servicing Advance.
After obtaining the broker's price opinion, the Servicer will determine, in its
reasonable business judgment, whether a net recovery is possible through
foreclosure proceedings or other liquidation of the related Mortgage Property.
If the Servicer determines that no such recovery is possible, it must charge off
the related Mortgage Loan at the time it becomes 180 days delinquent. Once a
Mortgage Loan has been charged off, the Servicer will discontinue making
Advances, the Servicer will not be entitled to future Servicing Fees (except as
provided below) with respect to such Mortgage Loan, and the Mortgage Loan will
be treated as a Liquidated Mortgage Loan. If the Servicer determines that such
net recovery is possible through foreclosure proceedings or other liquidation of
the related Mortgaged Property on a Mortgage Loan that becomes 180 days
delinquent, the Servicer need not charge off the Mortgage Loan and may continue
making Advances, the Servicer will continue to be entitled to Servicing Fees,
and the Servicer will be required to notify the Trustee of such decision.

          (e) Any Mortgage Loan that is charged off, pursuant to (d) above, may
continue to be serviced by the Servicer for the Certificateholders using
specialized collection procedures (including foreclosure, if appropriate). The
Servicer will be entitled to Servicing Fees and reimbursement of expenses in
connection with such Mortgage Loans after the date of charge off, only to the
extent of funds available from any recoveries on any such Mortgage Loans. Any
such Mortgage Loans serviced in accordance with the specialized collection
procedures shall be serviced for approximately six months. Any net recoveries
received on such Mortgage Loans during such six month period will be treated as
Subsequent Recoveries. On the date which is six months after the date on which
the Servicer begins servicing such Mortgage Loans using the specialized
collection procedures, unless specific net recoveries are anticipated by the
Servicer on a particular Mortgage Loan, such charged off loan will be released
to the majority holder of the Class C Certificates and thereafter, (i) the
majority holder of the Class C Certificates, as identified with contact
information in writing to the Servicer by the Depositor, will be entitled to any
amounts subsequently received in respect of any such released loans, subject to
the Servicer's fees described below, (ii) the majority holder of the Class C
Certificates may designate any servicer to service any such released loan, (iii)
the majority holder of the Class C Certificates may sell any such released loan
to a third party and (iv) to the extent the servicing of such charged off loan
is not transferred from the Servicer, the servicing of such charged off loan and
the fees therefor shall be governed by the most current servicing agreement
between the Servicer and the Sponsor.

     SECTION 3.13. Trustee to Cooperate; Release of Mortgage Files

     Upon the payment in full of any Mortgage Loan, or the receipt by the
Servicer of a notification that payment in full will be escrowed in a manner
customary for such purposes, the Servicer will promptly notify the Trustee or
its custodian by delivering a Request for Release substantially in the form of
Exhibit I. Upon receipt of a copy of such request, the Trustee or its custodian
shall promptly release the related Mortgage File to the Servicer, the cost of
which may be charged to the Servicer by the Trustee, and the Servicer is
authorized to cause the removal from the registration on the MERS System of any
such Mortgage if applicable, and the Servicer, on behalf of the Trustee shall
execute and deliver the request for reconveyance, deed of reconveyance or
release or satisfaction of mortgage or such instrument releasing the lien of the
Mortgage together with the Mortgage Note with written evidence of cancellation
thereon. Expenses incurred in connection with any instrument of satisfaction or
deed of reconveyance shall be chargeable to the Mortgagor to the extent
permitted by law, and otherwise to the Trust Fund to the extent such expenses
constitute "unanticipated expenses" within the meaning of Treasury Regulations
Section 1.860G-(1)(b)(3)(ii). From time to time and as shall be appropriate for

foreclosure of any Mortgage Loan, including for collection under any policy of
flood insurance, any fidelity bond or errors or omissions policy, or for the
purposes of effecting a partial release of any Mortgaged Property from the lien
of the Mortgage or the making of any corrections to the Mortgage Note or the
Mortgage or any of the other documents included in the Mortgage File, the
Trustee or its custodian shall, upon delivery to the Trustee or its custodian of
a Request for Release in the form of Exhibit I signed by a Servicing Officer,
release the Mortgage File to the Servicer, and the cost of delivery of the
Mortgage File may be charged to the Servicer by the Trustee. Subject to the
further limitations set forth below, the Servicer shall cause the Mortgage File
or documents so released to be returned to the Trustee or its custodian when the
need therefor by the Servicer no longer exists, unless the Mortgage Loan is
liquidated and the proceeds thereof are deposited in the Collection Account.

     Each Request for Release may be delivered to the Trustee or its custodian
(i) via mail or courier, (ii) via facsimile or (iii) by such other means,
including, without limitation, electronic or computer readable medium, as the
Servicer and the Trustee or its custodian shall mutually agree. The Trustee or
its custodian shall release the related Mortgage File(s) within four Business
Days of receipt of a properly completed Request for Release pursuant to clauses
(i), (ii) or (iii) above. Receipt of a properly completed Request for Release
shall be authorization to the Trustee or its custodian to release such Mortgage
Files, provided the Trustee or its custodian has determined that such Request
for Release has been executed, with respect to clauses (i) or (ii) above, or
approved, with respect to clause (iii) above, by an authorized Servicing Officer
of the Servicer, and so long as the Trustee or its custodian complies with its
duties and obligations under this Agreement. If the Trustee or its custodian is
unable to release the Mortgage Files within the period previously specified, the
Trustee or its custodian shall immediately notify the Servicer indicating the
reason for such delay. The Servicer shall not pay penalties or damages due to
the Trustee's or its designee's negligent failure to release the related
Mortgage File or the Trustee's or its designee's negligent failure to execute
and release documents in a timely manner, and such amounts shall be Servicer
Advances.

     On each day that the Servicer remits to the Trustee or its custodian
Requests for Releases pursuant to clauses (ii) or (iii) above, the Servicer
shall also submit to the Trustee or its custodian a summary of the total number
of such Requests for Releases requested on such day by the same method as
described in such clauses (ii) and (iii) above.

     If the Servicer at any time seeks to initiate a foreclosure proceeding in
respect of any Mortgaged Property as authorized by this Agreement, the Servicer
may deliver or cause to be delivered to the Trustee for signature, execute any
court pleadings, requests for trustee's sale or other documents necessary to
effectuate such foreclosure or any legal action brought to obtain judgment
against the Mortgagor on the Mortgage Note or the Mortgage or to obtain a
deficiency judgment or to enforce any other remedies or rights provided by the
Mortgage Note or the Mortgage or otherwise available at law or in equity.
Notwithstanding the foregoing, the Servicer shall cause possession of any
Mortgage File or of the documents therein that shall have been released by the
Trustee or the custodian on its behalf to be returned to the Trustee or the
custodian on its behalf promptly after possession thereof shall have been
released by the Trustee or the custodian on its behalf unless (i) the Mortgage
Loan has been liquidated and the Liquidation Proceeds relating to the Mortgage
Loan have been deposited in the Collection Account, and the Servicer shall have
delivered to the Trustee or the custodian on its behalf a Request for Release in
the form of Exhibit I or (ii) the Mortgage File or document shall have been
delivered to an attorney or to a public trustee or other public official as
required by law for purposes of initiating or pursuing legal action or other
proceedings for the foreclosure of the Mortgaged Property and the Servicer shall
have delivered to the Trustee or the custodian on its behalf an Officer's
Certificate of a Servicing Officer certifying as to the name and address of the
Person to which the Mortgage File or the documents therein were delivered and
the purpose or purposes of such delivery.

limited to, any funds on deposit in the Collection Account, shall be held by the
Servicer for and on behalf of the Trustee and shall be and remain the sole and
exclusive property of the Trust Fund, subject to the applicable provisions of
this Agreement. The Servicer also agrees that it shall not create, incur or
subject any Mortgage File or any funds that are deposited in the Collection
Account, the Certificate Account or in any Escrow Account, or any funds that
otherwise are or may become due or payable to the Trustee for the benefit of the
Certificateholders, to any claim, lien, security interest, judgment, levy, writ
of attachment or other encumbrance, or assert by legal action or otherwise any
claim or right of set off against any Mortgage File or any funds collected on,
or in connection with, a Mortgage Loan, except, however, that the Servicer shall
be entitled to set off against and deduct from any such funds any amounts that
are properly due and payable to the Servicer under this Agreement.

     SECTION 3.15. Servicing Compensation

     As compensation for its activities hereunder, the Servicer shall be
entitled to retain or withdraw from the Collection Account out of each payment
of interest on a Mortgage Loan included in the Trust Fund an amount equal to
interest at the applicable Servicing Fee Rate on the Stated Principal Balance of
the related Mortgage Loan as of the immediately preceding Distribution Date.

payment fees, assumption fees (i.e. fees related to the assumption of a Mortgage
Loan upon the purchase of the related Mortgaged Property) and similar fees
payable by the Mortgagor, Prepayment Interest Excess, all income and gain net of
any losses realized from Permitted Investments in the Collection Account, and
any other benefits arising from the Collection Account and the Escrow Account
shall be retained by the Servicer to the extent not required to be deposited in
the Collection Account and the Escrow Account pursuant to Sections 3.05, 3.06 or
3.12(a) hereof. The Servicer shall be required to pay all expenses incurred by
it in connection with its servicing activities hereunder and shall not be
entitled to reimbursement therefor except as specifically provided in this
Agreement. In no event shall the Trustee be liable for any Servicing Fee or for
any differential between the Servicing Fee and the amount necessary to induce a
successor servicer to act as successor servicer under this Agreement.

     SECTION 3.16. Access to Certain Documentation

     The Servicer shall provide to the OTS and the FDIC and to comparable
regulatory authorities supervising Holders of the Certificates and the examiners
and supervisory agents of the OTS, the FDIC and such other authorities, as
applicable, access to the documentation regarding the Mortgage Loans required by
applicable regulations of the OTS and the FDIC. Such access shall be afforded
without charge, but only upon reasonable and prior written request and during
normal business hours at the offices of the Servicer designated by it provided,
that the Servicer shall be entitled to be reimbursed by each such
Certificateholder for actual expenses incurred by the Servicer in providing such
reports and access. Nothing in this Section shall limit the obligation of the
Servicer to observe any applicable law prohibiting disclosure of information
regarding the Mortgagors and the failure of the Servicer to provide access as
provided in this Section as a result of such obligation shall not constitute a
breach of this Section. Upon reasonable advance notice to the Servicer, the
Trustee shall have the right to inspect and examine the books and records of the
Servicer with respect to the Mortgage Loans.

it deems necessary, forward to the Trustee in EDGAR-compatible form, or in such
other form as otherwise agreed upon by the Trustee and the Depositor, the form
and substance of the Additional Form 10-K Disclosure by March 15. The Depositor

draft copy of the Form 10-K to the Depositor and the Servicer for review. Upon
the request of the Servicer, the Depositor shall confirm that it has reviewed
the Form 10-K, that it has been properly prepared and that the Servicer may rely
on the accuracy thereof (other than with respect to any portion of the Form 10-K
or any exhibit thereto provided by the Servicer (other than any portion thereof
with respect to which the Servicer has relied on the Trustee)). No later than
5:00pm EST on the 3rd Business Day following receipt of a final copy of the Form
10-K and if requested, the above-described confirmation from the Depositor, a
senior officer of the Servicer shall sign the Form 10-K and return an electronic
or fax copy of such signed Form 10-K (with an original executed hard copy to
follow by overnight mail) to the Trustee and the Trustee shall file such Form
10-K by March 30th. If a Form 10-K cannot be filed on time or if a previously
filed Form 10-K needs to be amended, the Trustee will follow the procedures set
forth in the Agreement. After filing with the Commission, the Trustee will,
pursuant to the Agreement, make available on its internet website a final
executed copy of each Form 10-K. the Trustee shall have no liability with
respect to any failure to properly prepare, execute or file such Form 10-K
resulting from the Trustee's inability or failure to obtain or receive any
information needed to prepare, arrange for execution or file such Form 10-K on a
timely basis.

     Each Form 10-K shall include a certification (the "Sarbanes-Oxley
Certification") which shall be in the form attached hereto as Exhibit T. The
Servicer will cause its senior officer in charge of securitization to execute
the Sarbanes-Oxley Certification required pursuant to Rule 13a -14 under the
Securities Exchange Act of 1934, as amended, and to deliver the original
executed Sarbanes-Oxley Certification to the Trustee by March 20 of each year in
which the Issuing Entity is subject to the reporting requirements of the
Exchange Act. In connection therewith, each of the Trustee, the Servicer and
each Subservicer and Subcontractor engaged by such party shall sign an Officer's
Certificate (in the form attached hereto as Exhibit K and Exhibit L,
respectively) for the benefit of the Servicer and its officers, directors and
Affiliates regarding certain aspects of the Sarbanes-Oxley Certification. To the
extent any information or exhibits required to be included in the Form 10-K are
not timely received by the Trustee prior to March 30, the Trustee shall, on
behalf of the Issuing Entity, file a Form 12B-25 and one or more amended Form
10-Ks, to the extent such amendments are accepted by the Exchange Act, to
include such missing information or exhibits promptly after receipt thereof by
the Trustee.

     On or before January 30, 2007, the Trustee shall, if legally permissible
under applicable regulations and interpretations of the Commission, on behalf of
the Issuing Entity and in accordance with industry standards, file with the
Commission via EDGAR a Form 15 Suspension Notification with respect to the
Issuing Entity, if applicable.

                                      -99-

     The Servicer agrees to furnish promptly to the Trustee, from time to time
upon request, such further information, reports, and financial statements within
its control related to this Agreement and the Mortgage Loans as is reasonably
necessary to prepare and file all necessary reports with the Commission. The
Trustee shall have no responsibility to file any items with the Commission other
than those specified in this section and the Servicer shall execute any and all
Form 8-Ks and 10-Ks required hereunder.

     If the Commission issues additional interpretative guidance or promulgates
additional rules or regulations with respect to Regulation AB or otherwise, or
if other changes in applicable law occur, that would require the reporting
arrangements, or the allocation of responsibilities with respect thereto,
described in this Section 3.20, to be conducted differently than as described,
the Depositor, the Servicer, and the Trustee will reasonably cooperate to amend
the provisions of this Section 3.20 in order to comply with such amended
reporting requirements and such amendment of this Section 3.20. Any such
amendment shall be made in accordance with Section 10.01 without the consent of
the Certificateholders and may result in a change in the reports filed by the
Trustee on behalf of the Issuing Entity under the Exchange Act. Notwithstanding
the foregoing, the Depositor, the Servicer and the Trustee shall not be
obligated to enter into any amendment pursuant to this Section 3.20 that
adversely affects its obligations and immunities under this Agreement.

     The Depositor, the Servicer and the Trustee agree to use their good faith
efforts to cooperate in complying with the requirements of this Section 3.20.

     SECTION 3.21. Indemnification by Trustee

     The Trustee shall indemnify and hold harmless the Depositor, the Servicer
and their respective officers, directors, agents and Affiliates from and against
any losses, damages, penalties, fines, forfeitures, reasonable legal fees and
related costs, judgments and other costs and expenses arising out of or based
upon a breach by the Trustee or any of its officers, directors, agents or
Affiliates of its obligations under Sections 3.18 and 3.20, any material
misstatement or omission in any documents prepared thereunder (to the extent the
Trustee is responsible for providing information or calculating amounts included
in such information), the failure of the Trustee to deliver when required any
Assessment of Compliance or Accountant's Attestation required of it pursuant to
Section 3.18, or any material misstatement or omission contained in any
Assessment of Compliance or Accountant's Attestation provided on its behalf
pursuant to Section 3.18, or the negligence, bad faith or willful misconduct of
the Trustee in connection therewith. If the indemnification provided for herein
is unavailable or insufficient to hold harmless the indemnified parties, then
the Trustee agrees that it shall contribute to the amount paid or payable by the
indemnified parties as a result of the losses, claims, damages or liabilities of
the indemnified parties in such proportion as is appropriate to reflect the
relative fault of the Trustee on the one hand and of the indemnified parties on
the other.

     SECTION 3.22. Indemnification by Servicer

     The Servicer shall indemnify and hold harmless the Trustee and the
Depositor and their respective officers, directors, agents and Affiliates from
and against any losses, damages, penalties, fines, forfeitures, reasonable legal
fees and related costs, judgments and other costs and expenses arising out of or
based upon a breach by the Servicer or any of its officers, directors, agents or
Affiliates of its obligations under Sections 3.17, 3.18 and 3.20, any material
misstatement or omission in any documents prepared thereunder (to the extent the
Servicer is responsible for providing information or calculating amounts
included in such information), the failure of such Servicer or any related
Sub-Servicer or Subcontractor to deliver or cause to be delivered when required
any Assessment of Compliance or Accountant's Attestation required of it pursuant
to Section 3.18 or Annual Statement of Compliance

                                      -100-

<PAGE>

required pursuant to Section 3.17, as applicable, or any material misstatement
or omission contained in any Assessment of Compliance, Accountant's Attestation
or Annual Statement as to Compliance provided on its behalf pursuant to Section
3.18 or 3.17, as applicable, or the negligence, bad faith or willful misconduct
of the Servicer in connection therewith. If the indemnification provided for
herein is unavailable or insufficient to hold harmless the indemnified parties,
then the Servicer agrees that it shall contribute to the amount paid or payable
by the indemnified parties as a result of the losses, claims, damages or
liabilities of the indemnified parties in such proportion as is appropriate to
reflect the relative fault of the Servicer on the one hand and the indemnified
parties on the other.

     SECTION 3.23. Prepayment Charge Reporting Requirements

     Promptly after each Distribution Date, the Servicer shall provide to the
Depositor and the Trustee the following information with regard to each Mortgage
Loan that has prepaid during the related Prepayment Period:

          (i) loan number;

          (ii) current Mortgage Rate;

          (iii) current principal balance;

          (iv) original principal balance;

          (v) Prepayment Charge amount due; and

          (vi) Prepayment Charge amount collected.

     SECTION 3.24. Information to the Trustee

     Two Business Days after the 15th day of each month, but not later than the
18th day of each month, the Servicer shall furnish to the Trustee in electronic
format (i) the Remittance Report pursuant to Section 4.04(j) and (ii) a
delinquency report in such form or forms as the Trustee and the Servicer may
from time to time agree for the period ending on the last Business Day of the
preceding month (and with respect to prepayments in full, for the period ending
on the 14th day of the month in which such report is to be furnished).

     SECTION 3.25. Indemnification

     The Servicer shall indemnify the Sponsor, the Trust Fund, the Trustee (in
its individual capacity and in its capacity as trustee), the Depositor and their
officers, directors, employees and agents and hold each of them harmless against
any and all claims, losses, damages, penalties, fines, forfeitures, reasonable
and necessary legal fees and related costs, judgments, and any other costs, fees
and expenses that any of such parties may sustain in any way related to the
failure of the Servicer to perform its duties and service the related Mortgage
Loans in compliance with the terms of this agreement by reason of negligence,
willful misfeasance or bad faith in the performance of its duties or by reason
of reckless disregard of obligations and duties hereunder. The Servicer
immediately shall notify the Sponsor, the Trustee and the Depositor or any other
relevant party if a claim is made by a third party with respect to such party
and this Agreement or the related Mortgage Loans and, if subject to this
indemnification obligation, assume (with the prior written consent of the
indemnified party, which consent shall not be unreasonably withheld or delayed)
the defense of any such claim and pay all expenses in connection therewith,
including counsel fees, and promptly pay, discharge and satisfy any judgment or
decree which may be entered against it or

                                      -101-

<PAGE>

any of such parties in respect of such claim. The Servicer shall follow any
reasonable written instructions received from the Trustee in connection with
such claim, it being understood that the Trustee shall have no duty to monitor
or give instructions with respect to such claims, and the Servicer will not have
any liability for following such instructions. The Servicer shall provide the
Depositor and the Trustee with a written report of all expenses and advances
incurred by the Servicer pursuant to this Section 3.25, and the Servicer shall
promptly reimburse itself from the assets of the Trust Fund in the Collection
Account for all amounts advanced by it pursuant to the preceding sentence except
when the claim in any way relates to the gross negligence, bad faith or willful
misconduct of the Servicer. The provisions of this paragraph shall survive the
termination of this Agreement and the payment of the outstanding Certificates.

     SECTION 3.26. Solicitation

     The Servicer may solicit or refer to a mortgage originator, who may or may
not be an affiliate of the Depositor or the Servicer, any Mortgagor for
refinancing or otherwise take action to encourage refinancing.

     SECTION 3.27. High Cost Mortgage Loans

     In the event that the Servicer reasonably determines that a Mortgage Loan
may be a "high cost mortgage loan", "high cost home", "covered", "high cost",
"high risk home", "predatory" or similarly classified loan under any applicable
state, federal or local law, the Servicer may notify the Depositor, the Sponsor
and the Trustee thereof; the Servicer may terminate its servicing thereof; and
such determination shall be deemed to materially and adversely affect the
interests of the Certificateholders in such Mortgage Loan and the Transferor, or
the Sponsor, in event the Transferor does not do so, will repurchase the
Mortgage Loan within a 30 day period from the date of the notice in the manner
described in Section 2.05.

     SECTION 3.28. Special Servicing Agreements

     The Servicer may enter into a special servicing advisory agreement with (i)
a holder of (a) the Class R Certificate, (b) the Class C Certificate, (c) one or
more other Class of subordinated certificates issued by the Issuing Entity
and/or (d) a NIM Note and/or (ii) an advisor designated by any of the foregoing.
Pursuant to such agreement, the Servicer may provide such holder or advisor, in
its capacity as special servicing advisor, with loan-level information with
respect to the Mortgage Loans, and such person may advise the Servicer with
respect to efforts to maximize recoveries with regard to the Mortgage Loans,
including, without limitation, the commencement of foreclosure proceedings or
other actions.

     SECTION 3.29. Subordination of Liens

     In connection with any governmental program under which a Mortgagor may
obtain a benefit in the event the related Mortgaged Property is subject to a
disaster provided that the Mortgagor files a covenant or other lien against the
Mortgaged Property and is required to obtain the subordination thereto of the
Mortgage, the Servicer may cause such subordination to be executed and filed
provided that either (i) the related Mortgage Loan is in default or default with
respect to such Mortgage Loan is imminent or (ii) such subordination and
participation in such governmental program will not result in a change in
payment expectations with respect to such Mortgage Loan. For purposes of the
preceding sentence, a change in payment expectations occurs if, as a result of
such subordination and participation in such governmental program, (1) there is
a substantial enhancement of the Mortgagor's capacity to meet the payment
obligations under the Mortgage Loan and that capacity was primarily speculative
prior to such subordination and participation in such governmental program and
is adequate after such subordination

                                      -102-

<PAGE>

and participation in such governmental program or (2) there is a substantial
impairment of the Mortgagor's capacity to meet the payment obligations under the
Mortgage Loan and that capacity was adequate prior to such subordination and
participation in such governmental program and is primarily speculative after
such subordination and participation in such governmental program. The preceding
sentence and clause (ii) of the second preceding sentence are intended to comply
with Treasury Regulations Section 1.1001-3(e)(4) and shall be interpreted in
accordance therewith.

     SECTION 3.30. MI Policy; Claims Under the MI Policy

     Notwithstanding anything to the contrary elsewhere in this Agreement, the
Servicer shall not agree to any modification or assumption of a MI Mortgage Loan
or take any other action with respect to an MI Mortgage Loan that could result
in denial of coverage under the MI Policy. The Servicer shall notify the MI
Insurer that the Trustee, on behalf of the Issuing Entity, is the "Insured," as
that term is defined in the related MI Policy, of each MI Mortgage Loan insured
by the MI Insurer; provided, that such designation is made solely for the
purpose of entitling the Trust Fund to receive payments for claims under the MI
Policy and the Trustee shall not, except as provided herein, be deemed to assume
the obligations of the "Insured" thereunder. The Servicer shall, on behalf of
the Trustee, prepare and file on a timely basis with the MI Insurer all claims
that may be made under the MI Policy with respect to the MI Mortgage Loans.
Consistent with all rights and obligations hereunder, the Servicer shall take
all actions required under the MI Policy as a condition to the payment of any
such claim. Any amount received by the Servicer from the MI Insurer with respect
to any MI Mortgage Loan shall be deposited by the Servicer, no later than two
Business Days following receipt thereof, into the Collection Account.

                                   ARTICLE IV

                                  DISTRIBUTIONS

     SECTION 4.01. Advances

          (a) Subject to the conditions of this Article IV, the Servicer, as
required below, shall make an Advance and deposit such Advance in the Collection
Account. The Servicer shall use commercially reasonable efforts to remit each
such Advance no later than 2:30 p.m. EST, but in any case no later than 4:00
p.m. EST, on the Servicer Advance Date in immediately available funds. The
Servicer shall be obligated to make any such Advance only to the extent that
such advance would not be a Non-Recoverable Advance. If the Servicer shall have
determined that it has made a Non-Recoverable Advance or that a proposed Advance
or a lesser portion of such Advance would constitute a Non-Recoverable Advance,
the Servicer shall deliver (i) to the Trustee for the benefit of the
Certificateholders, funds constituting the remaining portion of such Advance, if
applicable, and (ii) to the Depositor, each Rating Agency, the NIMs Insurer and
the Trustee an Officer's Certificate setting forth the basis for such
determination. The Servicer may, in its sole discretion, make an Advance with
respect to the principal portion of the final Scheduled Payment on a Balloon
Loan, but the Servicer is under no obligation to do so; provided, however, that
nothing in this sentence shall affect the Servicer's obligation under this
Section 4.01 to Advance the interest portion of the final Scheduled Payment with
respect to a Balloon Loan as if such Balloon Loan were a fully amortizing
Mortgage Loan. If a Mortgagor does not pay its final Scheduled Payment on a
Balloon Loan when due, the Servicer shall Advance (unless it determines in its
good faith judgment that such amounts would constitute a Non-Recoverable
Advance) a full month of interest (net of the Servicing Fee) on the Stated
Principal Balance thereof each month until its Stated Principal Balance is
reduced to zero.

                                      -103-

<PAGE>

     In lieu of making all or a portion of such Advance from its own funds, the
Servicer may (i) cause to be made an appropriate entry in its records relating
to the Collection Account that any amount held for future distribution has been
used by the Servicer in discharge of its obligation to make any such Advance and
(ii) transfer such funds from the Collection Account to the Certificate Account.
In addition, the Servicer shall have the right to reimburse itself for any such
Advance from amounts held from time to time in the Collection Account to the
extent such amounts are not then required to be distributed. Any funds so
applied and transferred pursuant to the previous two sentences shall be replaced
by the Servicer by deposit in the Collection Account no later than the close of
business on the Servicer Advance Date on which such funds are required to be
distributed pursuant to this Agreement. The Servicer shall be entitled to be
reimbursed from the Collection Account for all Advances of its own funds made
pursuant to this Section as provided in Section 3.08. The obligation to make
Advances with respect to any Mortgage Loan shall continue until the earlier of
(i) such Mortgage Loan is paid in full, (ii) the related Mortgaged Property or
related REO Property has been liquidated or until the purchase or repurchase
thereof (or substitution therefor) from the Issuing Entity pursuant to any
applicable provision of this Agreement, except as otherwise provided in this
Section 4.01, (iii) the Servicer determines in its good faith judgment that such
amounts would constitute a Non-Recoverable Advance as provided in the preceding
paragraph or (iv) the date on which such Mortgage Loan becomes 150 days
delinquent as set forth below.

          (b) Notwithstanding anything in this Agreement to the contrary
(including, but not limited to, Sections 3.01 and 4.01(a) hereof), no Advance or
Servicing Advance shall be required to be made hereunder by the Servicer
(including for the avoidance of doubt, the Trustee as successor servicer) if
such Advance or Servicing Advance would, if made, constitute a Non-Recoverable
Advance or a Non-Recoverable Servicing Advance. The determination by the
Servicer that it has made a Non-Recoverable Advance or a Non-Recoverable
Servicing Advance or that any proposed Advance or Servicing Advance, if made,
would constitute a Non-Recoverable Advance or a Non-Recoverable Servicing
Advance, respectively, shall be evidenced by an Officer's Certificate of the
Servicer delivered to the Depositor and the Trustee. In addition, the Servicer
shall not be required to advance any Relief Act Shortfalls.

          (c) Notwithstanding the foregoing, the Servicer shall not be required
to make any Advances for any Mortgage Loan after such Mortgage Loan becomes 150
days delinquent. The Servicer shall identify such delinquent Mortgage Loans in
the Servicer Statement referenced in Section 3.24. In addition, the Servicer
shall provide the Trustee with an Officer's Certificate listing such delinquent
Mortgage Loans and certifying that such loans are 150 days or more delinquent.

     SECTION 4.02. Reduction of Servicing Compensation in Connection with
Prepayment Interest Shortfalls

     In the event that any Mortgage Loan is the subject of a Prepayment Interest
Shortfall, the Servicer shall, from amounts in respect of the Servicing Fee for
such Distribution Date, deposit into the Collection Account, as a reduction of
the Servicing Fee for such Distribution Date, no later than the Servicer Advance
Date immediately preceding such Distribution Date, an amount up to the
Prepayment Interest Shortfall. In case of such deposit, the Servicer shall not
be entitled to any recovery or reimbursement from the Depositor, the Trustee,
the Issuing Entity or the Certificateholders. With respect to any Distribution
Date, to the extent that the Prepayment Interest Shortfall exceeds Compensating
Interest (such excess, a "Non-Supported Interest Shortfall"), such Non-Supported
Interest Shortfall shall reduce the Current Interest with respect to each Class
of Certificates, pro rata based upon the amount of interest each such Class
would otherwise be entitled to receive on such Distribution Date.

     SECTION 4.03. Distributions on the REMIC Interests

                                      -104-

<PAGE>

     On each Distribution Date, amounts on deposit in the Certificate Account
shall be treated for federal income tax purposes as applied to distributions on
the interests in each of the SWAP REMIC and the Lower Tier REMIC in an amount
sufficient to make the distributions on the respective Certificates on such
Distribution Date in accordance with the provisions of Section 4.04.

     SECTION 4.04. Distributions

          (a) [Reserved].

          (b) On each Distribution Date (or on the related Swap Payment Date,
with respect to payments to the Supplemental Interest Trust), the Trustee shall,
to the extent of funds then available, make the following distributions from
funds then available in the Certificate Account, of an amount equal to the
Interest Funds, in the following order of priority:

          (i) to the Class P Certificates, an amount equal to any Prepayment
     Charges received with respect to the Mortgage Loans and all amounts paid by
     the Servicer, the Sponsor or the Transferor in respect of Prepayment
     Charges pursuant to this Agreement or the Transfer Agreement, as
     applicable, and all amounts received in respect of any indemnification paid
     as a result of a Prepayment Charge being unenforceable in breach of the
     representations and warranties set forth in the Sale Agreement or the
     Transfer Agreement for the related Prepayment Period;

          (ii) to the Supplemental Interest Trust, any Net Swap Payments owed to
     the Swap Counterparty;

          (iii) to the Supplemental Interest Trust, any Swap Termination Payment
     owed to the Swap Counterparty (other than any Defaulted Swap Termination
     Payment);

          (iv) concurrently, to each Class of the Class A Certificates, the
     Current Interest and any Interest Carry Forward Amount with respect to each
     such Class; provided, however, that if Interest Funds are insufficient to
     make a full distribution of the aggregate Current Interest and the
     aggregate Interest Carry Forward Amount to the Class A Certificates,
     Interest Funds will be distributed pro rata among each Class of the Class A
     Certificates based upon the ratio of (x) the Current Interest and Interest
     Carry Forward Amount for each Class of the Class A Certificates to (y) the
     total amount of Current Interest and any Interest Carry Forward Amount for
     the Class A Certificates in the aggregate;

          (v) to the Class M-1 Certificates, the Current Interest for such Class
     and any Interest Carry Forward Amount with respect to such Class;

          (vi) to the Class M-2 Certificates, the Current Interest for such
     Class and any Interest Carry Forward Amount with respect to such Class;

          (vii) to the Class M-3 Certificates, the Current Interest for such
     Class and any Interest Carry Forward Amount with respect to such Class;

          (viii) to the Class M-4 Certificates, the Current Interest for such
     Class and any Interest Carry Forward Amount with respect to such Class;

          (ix) to the Class M-5 Certificates, the Current Interest for such
     Class and any Interest Carry Forward Amount with respect to such Class;

                                      -105-

<PAGE>

          (x) to the Class M-6 Certificates, the Current Interest for such Class
     and any Interest Carry Forward Amount with respect to such Class;

          (xi) to the Class B-1 Certificates, the Current Interest for each such
     Class and any Interest Carry Forward Amount with respect to each such
     Class;

          (xii) to the Class B-2 Certificates, the Current Interest for each
     such Class and any Interest Carry Forward Amount with respect to each such
     Class;

          (xiii) to the Class B-3 Certificates, the Current Interest for each
     such Class and any Interest Carry Forward Amount with respect to each such
     Class; and

          (xiv) any remainder pursuant to Section 4.04(f) hereof.

     On each Distribution Date, subject to the proviso in (iv) above, Interest
Funds received on the Group One Mortgage Loans will be deemed to be distributed
to the Class R and Class A-1 Certificates and Interest Funds received on the
Group Two Mortgage Loans will be deemed to be distributed to the Class A-2
Certificates, in each case, until the related Current Interest and Interest
Carry Forward Amount of each such Class of Certificates for such Distribution
Date has been paid in full. Thereafter, Interest Funds not required for such
distributions are available to be applied to if necessary, to the Class or
Classes of Certificates that are not related to such group of Mortgage Loans.

          (c) [Reserved]

          (d) On each Distribution Date (or on the related Swap Payment Date,
with respect to payments to the Supplemental Interest Trust), the Trustee shall,
to the extent of funds then available, make the following distributions from the
Certificate Account of an amount equal to the Principal Distribution Amount in
the following order of priority, and each such distribution shall be made only
after all distributions pursuant to Section 4.04(b) above shall have been made
until such amount shall have been fully distributed for such Distribution Date:

          (i) to the Supplemental Interest Trust, any Net Swap Payments owed to
     the Swap Counterparty, to the extent not paid pursuant to Section
     4.04(b)(ii);

          (ii) to the Supplemental Interest Trust, any Swap Termination Payment
     owed to the Swap Counterparty (other than any Defaulted Swap Termination
     Payment), to the extent not paid pursuant to Section 4.04(b)(iii);

          (iii) to the Class A Certificates, the Class A Principal Distribution
     Amount shall be distributed as follows:

               (A) the Group One Principal Distribution Amount will be
          distributed as follows: (A) first, to the Class R Certificate, until
          the Certificate Principal Balance of such Class has been reduced to
          zero and (B) second, to the Class A-1 Certificates, until the
          Certificate Principal Balance of such Class has been reduced to zero;

               (B) the Group Two Principal Distribution Amount will be
          distributed as follows: sequentially, to the Class A-2A Certificates
          until the Certificate Principal Balance thereof has been reduced to
          zero, then to the Class A-2B Certificates until the Certificate
          Principal Balance thereof has been reduced to zero and then to the
          Class A-2C Certificates until the Certificate Principal Balance
          thereof has been reduced to zero;

                                      -106-

<PAGE>

          provided, however, that on and after the Distribution Date on which
          the aggregate Certificate Principal Balance of the Class M, Class B
          and Class C Certificates has been reduced to zero, any principal
          distributions allocated to the Class A-2A, Class A-2B and Class A-2C
          Certificates are required to be allocated pro rata, among such
          Classes, based on their respective Certificate Principal Balances,
          until their Certificate Principal Balances have been reduced to zero;

          (iv) to the Class M-1 Certificates, the Class M-1 Principal
     Distribution Amount;

          (v) to the Class M-2 Certificates, the Class M-2 Principal

          (j) Subject to Section 9.02 hereof respecting the final distribution,
on each Distribution Date the Trustee shall make distributions to each
Certificateholder of record on the preceding Record Date either by wire transfer
in immediately available funds to the account of such holder at a bank or other
entity having appropriate facilities therefor, or if such Holder has so notified
the Trustee at least five (5) Business Days prior to the related Record Date or
has not provided wiring instructions to the Trustee, by check mailed by first
class mail to such Certificateholder at the address of such holder appearing in
the Certificate Register. Notwithstanding the foregoing, but subject to Section
9.02 hereof respecting the final distribution, distributions with respect to
Certificates registered in the name of a Depository shall be made to such
Depository in immediately available funds.

     In accordance with this Agreement, the Servicer shall prepare and deliver
an electronic report (the "Remittance Report") to the Trustee (or by such other
means as the Servicer and the Trustee may agree from time to time) containing
such data and information as to permit the Trustee to prepare the Monthly
Statement to Certificateholders and make the required distributions for the
related Distribution Date. The Trustee will prepare the Monthly Report based
solely upon the information received from the Servicer.

     The Trustee shall promptly notify the NIMs Insurer of any proceeding or the
institution of any action, of which a Responsible Officer of the Trustee has
actual knowledge, seeking the avoidance as a preferential transfer under
applicable bankruptcy, insolvency, receivership or similar law (a "Preference
Claim") of any distribution made with respect to the Class C Certificates or the
Class P Certificates. Each Holder of the Class C Certificates or the Class P
Certificates, by its purchase of such Certificates and the Trustee hereby agree
that the NIMs Insurer may at any time during the continuation of any proceeding
relating to a Preference Claim direct all matters relating to such Preference
Claim, including, without limitation, (i) the direction of any appeal of any
order relating to such Preference Claim and (ii) the posting of any surety,
supersedes or performance bond pending any such appeal. In addition and without
limitation of the foregoing, the NIMs Insurer shall be subrogated to the rights
of the Trustee and each Holder of the Class C Certificates and the Class P
Certificates in the conduct of any such Preference

                                      -109-

<PAGE>

Claim, including, without limitation, all rights of any party to an adversary
proceeding action with respect to any court order issued in connection with any
such Preference Claim; provided, however, that the NIMs Insurer will not have
any rights with respect to any Preference Claim set forth in this paragraph
unless the indenture trustee with respect to the NIM Notes or the holder of any
NIMs Notes has been required to relinquish a distribution made on the Class C
Certificates, the Class P Certificates or the NIM Notes, as applicable, and the
NIMs Insurer made a payment in respect of such relinquished amount.

          (k) The Trustee is hereby directed by the Depositor to execute the Cap
Contracts on behalf of the Supplemental Interest Trust in the form presented to
it by the Depositor and shall have no responsibility for the contents of such
Cap Contract, including, without limitation, the representations and warranties
contained therein. Any funds payable by the Trustee under the Cap Contracts at
closing shall be paid by the Depositor. Notwithstanding anything to the contrary
contained herein or in any Cap Contract, except as set forth in paragraph 2 of
the confirmation to each Cap Contract and paragraph 13(b) to the Cap Credit
Support Annex, the Issuing Entity shall not be required to make any payments to
the counterparty under any Cap Contract. Any payments received under the terms
of the related Cap Contract will be available to pay the holders of the related
Class A-1, Class A-2, Class M and Class B Certificates up to the amount of any
Floating Rate Certificate Carryovers remaining after all other distributions
required under this Section 4.04 are made on such Distribution Date, other than
Floating Rate Certificate Carryovers attributable to the fact that Applied
Realized Loss Amounts are not allocated to the Class A Certificates. Any amounts
(excluding collateral posted pursuant to a Cap Credit Support Annex) received
under the terms of any Cap Contract on a Distribution Date that are not used to
pay such Floating Rate Certificate Carryovers will be distributed to the holders
of the Class C Certificates. Payments in respect of such Floating Rate
Certificate Carryovers from proceeds of a Cap Contract shall be paid to the
related Classes of Class A-1, Class A-2, Class M and Class B Certificates, pro
rata based upon such Floating Rate Certificate Carryovers for each such Class of
Class A-1, Class A-2, Class M and Class B Certificates. Amounts received on the
Class A-1 Cap Contract will only be available to make payments on the Class A-1
Certificates, amounts received on the Class A-2 Cap Contract will only be
available to make payments on the Class A-2 Certificates, amounts received on
the Subordinate Certificates Cap Contract will only be available to make
payments on the Subordinate Certificates.

          (i) The Trustee shall establish and maintain, for the benefit of the
     Issuing Entity and the Certificateholders, the Cap Contract Account. On or
     prior to the Cap Contract Termination Date, amounts, if any, received by
     the Trustee for the benefit of the Trust Fund in respect of the related Cap
     Contract shall be deposited by the Trustee into the Cap Contract Account
     and will be used to pay Floating Rate Certificate Carryovers on the related
     Class A-1, Class A-2, Class M and Class B Certificates to the extent
     provided in the immediately preceding paragraph. With respect to any
     Distribution Date on or prior to the Cap Contract Termination Date, the
     amount, if any, payable by the Cap Contract Counterparty under the related
     Cap Contract will equal the product of (i) the excess of (x) One-Month
     LIBOR (as determined by the Cap Contract Counterparty pursuant to the terms
     of such Cap Contract and subject to a cap equal to the rate with respect to
     such Distribution Date as shown under the heading "1ML Upper Collar" in the
     schedule to the related Cap Contract), over (y) the rate with respect to
     such Distribution Date as shown under the heading "1ML Strike Lower Collar"
     in the schedule to the related Cap Contract, (ii) an amount equal to the
     lesser of (x) the related Cap Contract Notional Balance for such
     Distribution Date and (y) the outstanding Certificate Principal Balance of
     the related Classes of Certificates and (iii) the number of days in such
     Accrual Period, divided by 360. If a payment is made to the Issuing Entity
     under a Cap Contract and the Trustee is required to distribute excess
     amounts to the holders of the Class C Certificates as described above,
     information regarding such distribution will be included in the monthly
     statement made available on the Trustee's website pursuant to Section 4.05
     hereof.

                                      -110-

<PAGE>

          (ii) Amounts on deposit in the Cap Contract Account will remain
     uninvested pending distribution to Certificateholders.

          (iii) Each Cap Contract is scheduled to remain in effect until the Cap
     Contract Termination Date and will be subject to early termination only in
     limited circumstances. Such circumstances include certain insolvency or
     bankruptcy events in relation to the Cap Contract Counterparty (after a
     grace period of three Local Business Days, as defined in the related Cap
     Contract, after notice of such failure is received by the Cap Contract
     Counterparty) to make a payment due under the related Cap Contract, the
     failure by the Cap Contract Counterparty (after a cure period of 20 days
     after notice of such failure is received) to perform any other agreement
     made by it under the related Cap Contract, the termination of the Trust
     Fund and the related Cap Contract becoming illegal or subject to certain
     kinds of taxation.

          (iv) On the Closing Date, the Cap Contract Counterparty and the
     Trustee (which is hereby authorized and directed to enter into such credit
     support annex) will enter into a credit support annex in relation to the
     Cap Contracts.

          Pursuant to and in accordance with the terms and provisions of the Cap
     Contracts, the Cap Contract Counterparty may be required to post additional
     collateral in connection with its obligations under the Cap Contracts. In
     connection with the foregoing, the Trustee shall establish a Cap Posted
     Collateral Account on the Closing Date.

          To the extent that the Cap Contract Counterparty remits any Posted
     Collateral to the Trustee under the Cap Contracts, the Trustee shall, upon
     receipt of the Posted Collateral, deposit the Posted Collateral into the
     Cap Posted Collateral Account and shall hold, release and disburse such
     collateral in accordance with the terms and provisions of the Cap
     Contracts. Where a termination event occurs with respect to the Cap
     Contract Counterparty under the Cap Contracts, or where the Cap Contract
     Counterparty fulfills certain obligations to the Issuing Entity such as
     finding a replacement cap contract counterparty or a guarantor that meets
     the criteria described in the Cap Contracts, the Trustee shall make
     payments from the Cap Posted Collateral Account in accordance with the
     provisions of the Cap Contracts. Amounts held in the Cap Posted Collateral
     Account will not be part of the Trust Fund and will not be available for
     distribution to any Certificateholders, except to the extent such funds are
     distributed to the Cap Contract Account pursuant to the Cap Contracts. Any
     funds held in the Cap Posted Collateral Account shall be invested by the
     Trustee in accordance with the provisions of the Cap Credit Support Annex.
     Any earnings shall be remitted to the Cap Contract Counterparty in
     accordance with the Cap Contracts. Absent receipt by the Trustee of written
     investment instructions pursuant to the Cap Credit Support Annex, funds
     held in the Cap Posted Collateral Account shall remain uninvested.

          (l) On the Closing Date, the Supplemental Interest Trust shall be
established and maintained pursuant to this Agreement, as a separate trust, the
corpus of which shall be held by the Supplemental Interest Trust Trustee for the
benefit of the holders of the Certificates as a segregated subtrust of the Trust
Fund. The Supplemental Interest Trust shall be an Eligible Account, and funds
deposited therein shall be held separate and apart from, and shall not be
commingled with, any other moneys, including, without limitation, other moneys
of the Trustee or Supplemental Interest Trust Trustee held pursuant to this
Agreement. In no event shall any funds deposited in the Supplemental Interest
Trust be credited to or made available to any other account of the Trust Fund.
The records of the Trustee shall at all times reflect that the Supplemental
Interest Trust is a subtrust of the Trust Fund, the assets of which are
segregated from other assets of the Trust Fund.

                                      -111-

     The Supplemental Interest Trust Trustee is hereby directed by the Depositor
to execute the Swap Agreement on behalf of the Supplemental Interest Trust in
the forms presented to it by the Depositor and shall have no responsibility for
the contents of such Swap Agreement, including, without limitation, the
representations and warranties contained therein. The Supplemental Interest
Trust Trustee shall have all of the rights and protections of the Trustee
hereunder.

     The Supplemental Interest Trust Trustee shall use reasonable efforts to
enforce all of the rights of the Supplemental Interest Trust and exercise any
remedies under the Swap Agreement and, in the event the Swap Agreement is
terminated as a result of the designation by either party thereto of an Early
Termination Date (as defined in the Swap Agreement), find a replacement
counterparty to enter into a replacement swap agreement utilizing the amounts of
the net Swap Termination Payments received.

     For each Distribution Date, through and including the Distribution Date in
December 2011, the Supplemental Interest Trust Trustee shall, based on the
Significance Estimate (which shall be provided to the Trustee by the Depositor
within five Business Days prior to the Distribution Date), calculate the
Significance Percentage of the Swap Agreement. If on any such Distribution Date,
the Significance Percentage is equal to or greater than 9%, the Supplemental
Interest Trust Trustee shall promptly notify the Depositor and the Depositor, on
behalf of the Trustee, shall obtain the financial information required to be
delivered by the Swap Counterparty pursuant to the terms of the Swap Agreement.
If, on any succeeding Distribution Date through and including the Distribution
Date in December 2011, the Significance Percentage is equal to or greater than
10%, the Supplemental Interest Trust Trustee shall promptly notify the Depositor
and the Depositor shall, within five Business Days after such Distribution Date,
deliver to the Trustee the financial information provided to it by the Swap
Counterparty for inclusion in the Form 10-D relating to such Distribution Date.

     Distributions with respect to amounts owed to the Swap Counterparty under
Sections 4.04(b) and 4.04(d) shall be deposited in the Swap Account and shall
be used to make the payments to the Swap Counterparty described in this
Section 4.04(l). Any Swap Termination Payment received by the Supplemental
Interest Trust Trustee from the Swap Counterparty shall be deposited in the Swap
Account and shall be used to make any upfront payment required under a
replacement swap agreement and any upfront payment received from the
counterparty to a replacement swap agreement shall be used to pay any Swap
Termination Payment owed to the Swap Counterparty.

     Notwithstanding anything contained herein, in the event that a replacement
swap agreement cannot be obtained within 30 days after receipt by the
Supplemental Interest Trust Trustee of the Swap Termination Payment paid by the
terminated Swap Counterparty, the Supplemental Interest Trust Trustee shall
deposit such Swap Termination Payment into a separate, segregated non-interest
bearing subtrust established by the Supplemental Interest Trust Trustee and the
Supplemental Interest Trust Trustee shall, on each Distribution Date following
receipt of such Swap Termination Payment, withdraw from such subtrust, an amount
equal to the Net Swap Payment, if any, that would have been paid to the
Supplemental Interest Trust by the original Swap Counterparty (computed in
accordance with the original Swap Agreement) and distribute such amount in
accordance with Section 4.04(l)(i)-(viii) of this Agreement. Any such subtrust
shall not be an asset of any REMIC. Any amounts remaining in such subtrust shall
be distributed to the holders of the Class C Certificates on the Distribution
Date following the earlier of (i) the termination of the Trust Fund pursuant to
Section 9.01 and (ii) December 25, 2011.

     On or before any Distribution Date (or in the case of any Net Swap
Payments, on the related Swap Payment Date), any Swap Termination Payments or
Net Swap Payments owed to the Swap Counterparty will be paid out of, or any Net
Swap Payments or Swap Termination Payments received from the Swap Counterparty
will be deposited into, the Swap Account. The Supplemental Interest Trust will
not be an asset of any REMIC. Funds in the Swap Account within the Supplemental
Interest Trust

                                      -112-

(other than any funds in the Cap Contract Account) shall be distributed in the
following order of priority by the Trustee:

          (i) to the Swap Counterparty, all Net Swap Payments, if any, owed to
     the Swap Counterparty for such Distribution Date;

          (ii) to the Swap Counterparty, any Swap Termination Payment, other
     than a Defaulted Swap Termination Payment, if any, owed to the Swap
     Counterparty;

          (iii) to each Class of the Class A Certificates, on a pro rata basis,
     any Current Interest and any Interest Carry Forward Amount with respect to
     such Class to the extent unpaid from Interest Funds and Principal Funds;

          (iv) sequentially, to the Class M-1 Certificates, the Class M-2
     Certificates, the Class M-3 Certificates, the Class M-4 Certificates, the
     Class M-5 Certificates, the Class M-6 Certificates, the Class B-1
     Certificates, the Class B-2 Certificates and the Class B-3 Certificates, in
     that order, any Current Interest for such Class to the extent unpaid from
     Interest Funds and Principal Funds;

          (v) sequentially, to the Class M-1 Certificates, the Class M-2
     Certificates, the Class M-3 Certificates, the Class M-4 Certificates, the
     Class M-5 Certificates, the Class M-6 Certificates, the Class B-1
     Certificates, the Class B-2 Certificates and the Class B-3 Certificates, in
     that order, any Interest Carry Forward with respect to such Class to the
     extent unpaid from Interest Funds and Principal Funds;

          (vi) to the Class A, Class R, Class M and Class B Certificates, to pay
     principal as described and in the same manner and order of priority as set
     forth in Sections 4.04(d)(iii) through 4.04(d)(xii) to the extent that
     funds are not otherwise available to pay the Extra Principal Distribution
     Amount;

          (vii) sequentially, to the Class M-1 Certificates, the Class M-2
     Certificates, the Class M-3 Certificates, the Class M-4 Certificates, the
     Class M-5 Certificates, the Class M-6 Certificates, the Class B-1
     Certificates, the Class B-2 Certificates, the Class B-3 Certificates, in
     that order, any Unpaid Realized Loss Amount for such Class to the extent
     unpaid from Interest Funds and Principal Funds;

          (viii) to the Class A, Class R, Class M and Class B Certificates, on a
     pro rata basis, any Floating Rate Certificate Carryover to the extent not
     paid based on the amount of such unpaid Floating Rate Certificate
     Carryover;

          (ix) to the Swap Counterparty, any Defaulted Swap Termination Payment
     owed to the Swap Counterparty to the extent not already paid; and

          (x) to the Class C Certificates any remaining amount.

     Notwithstanding the foregoing, however, after giving effect to proposed
distributions on any Distribution Date, the sum of the cumulative amounts
distributed pursuant to clause (vi) above and the cumulative amounts distributed
pursuant to clause (vii) above shall be limited to the aggregate amount of
cumulative Realized Losses incurred from the Cut-off Date through the last day
of the related Prepayment Period.

                                      -113-

<PAGE>

     Upon termination of the Trust Fund, any amounts remaining in the
Supplemental Interest Trust shall be distributed pursuant to the priorities set
forth in this Section 4.04(l).

     With respect to the failure of the Swap Counterparty to perform any of its
obligations under the Swap Agreement, the breach by the Swap Counterparty of any
of its representations and warranties made pursuant to the Swap Agreement, or
the termination of the Swap Agreement, the Trustee shall send any notices and
make any demands required hereunder.

     On the Closing Date, the Swap Counterparty and the Supplemental Interest
Trust Trustee (which is hereby authorized and directed to enter into such credit
support annex) will enter into a credit support annex in relation to the Swap
Agreement.

     Pursuant to and in accordance with the terms and provisions of the Swap
Agreement, the Swap Counterparty may be required to post additional collateral
in connection with its obligations under the Swap Agreement. In connection with
the foregoing, on the Closing Date, the Supplemental Interest Trust Trustee
shall establish and maintain a Swap Posted Collateral Account.

     To the extent that the Swap Counterparty remits any Posted Collateral to
the Supplemental Interest Trust Trustee under the Swap Agreement, the
Supplemental Interest Trust Trustee shall, upon receipt of the Posted
Collateral, deposit the Posted Collateral into the Swap Posted Collateral
Account and shall hold, release and disburse such collateral in accordance with
the terms and provisions of the Swap Agreement. Where a termination event occurs
with respect to the Swap Counterparty under the Swap Agreement, or where the
Swap Counterparty fulfills certain obligations to the Supplemental Interest
Trust such as finding a replacement swap counterparty or a guarantor that meets
established criteria of the Rating Agencies as set forth in the Swap Agreement,
the Supplemental Interest Trust Trustee shall make payments from the Swap Posted
Collateral Account in accordance with the provisions of the Swap Agreement.
Amounts held in the Swap Posted Collateral Account will not be part of the Trust
Fund and will not be available for distribution to any Certificateholders,
except to the extent distributed to the Swap Account pursuant to the Swap
Agreement. Any funds held in the Swap Posted Collateral Account shall be
invested by the Trustee in accordance with the provisions of the Swap Credit
Support Annex. Posted Collateral that is not cash shall be held by the
Supplemental Interest Trust Trustee and remain uninvested. Any earnings shall be
remitted to the Swap Counterparty in accordance with the Swap Agreement. Absent
receipt by the Trustee of written investment instructions pursuant to the Swap
Credit Support Annex, funds held in the Swap Posted Collateral Account shall
remain uninvested.

(1)  The Class C Certificates shall not have minimum dollar denominations or

     interest of 25%.

(2)  The Class P Certificates shall not have minimum dollar denominations or
     Certificate Principal Balances and shall be issued in a minimum percentage
     interest of 100%.

     The Certificates shall be executed by manual or facsimile signature on
behalf of the Trustee 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 Trustee shall bind
the Trust Fund, 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 Authenticating Agent 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 Authenticating Agent shall authenticate
the Certificates to be issued at the written direction of the Depositor, or any
Affiliate thereof.

     The Certificates sold in offshore transactions in reliance on Regulation S
shall be issued initially in the form of one or more permanent global
certificates in definitive, fully registered form without interest coupons with
the applicable legends set forth in Exhibit A hereto added to the form of each
such Certificate (each, a "Regulation S Book-Entry Certificate"), which shall be
deposited on behalf of the Holders of such Certificates represented thereby with
the Trustee, as custodian for DTC and registered in the name of a nominee of
DTC, duly executed and authenticated by the Trustee and the Authenticating Agent
as hereinafter provided. The aggregate principal amounts of the Regulation S
Book-Entry Certificates may from time to time be increased or decreased by
adjustments made on the records of the Trustee or DTC or its nominee, as the
case may be, as hereinafter provided.

     The Certificates sold in reliance on Rule 144A shall be issued initially in
the form of one or more permanent global certificates in definitive, fully
registered form without interest coupons with the applicable legends set forth
in Exhibit A hereto added to the form of each such Certificate (each, a "Rule
144A Book-Entry Certificate"), which shall be deposited on behalf of the Holders
of such Certificates represented thereby with the Trustee, as custodian for DTC
and registered in the name of a nominee of

DTC, duly executed and authenticated by the Trustee and the Authenticating Agent
as hereinafter provided. The aggregate principal amounts of the Rule 144A
Book-Entry Certificates may from time to time be increased or decreased by
adjustments made on the records of the Trustee or DTC or its nominee, as the
case may be, as hereinafter provided.

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

          (a) The Trustee shall maintain, or cause to be maintained in
accordance with the provisions of Section 5.09 hereof, a Certificate Register
for the Issuing Entity in which, subject to the provisions of subsections (b)
and (c) below and to such reasonable regulations as it may prescribe, the
Trustee 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 Authenticating Agent 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 Trustee. Whenever any Certificates are
so surrendered for exchange, the Trustee shall execute and the Authenticating
Agent shall authenticate and deliver the Certificates that the Certificateholder
making the exchange is entitled to receive. Every Certificate presented or
surrendered for registration of Transfer or exchange shall be accompanied by a
written instrument of Transfer in form satisfactory to the Trustee 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 a Trustee in accordance with such
Trustee's customary procedures.

     No Transfer of a Class C or Class P 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 C or Class P Certificate by Merrill
Lynch & Co. or, in connection with a transfer of a Class C or Class P
Certificate to the indenture trustee under an Indenture pursuant to which NIM
Notes are issued, whether or not such notes are guaranteed by the NIMs Insurer)
each certify to the Trustee in writing the facts surrounding the Transfer in
substantially the form set forth in Exhibit F (the "Transferor Certificate") and
(i) deliver a letter in substantially the form of either Exhibit G (the
"Investment Letter") or Exhibit H (the "Rule 144A Letter") or (ii) there shall
be delivered to the Trustee 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 Trustee. The Depositor shall provide
to any Holder of a Class C or Class P 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 Trustee shall
cooperate with the Depositor in providing the Rule 144A information referenced
in the preceding sentence, including providing to the

                                      -120-

<PAGE>

Depositor such information in the possession of the Trustee 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 C or Class P Certificate desiring to
effect such Transfer shall, and does hereby agree to, indemnify the Depositor
and the Trustee 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.

     By acceptance of a Regulation S Global Security, whether upon original
issuance or subsequent transfer, each Holder of such a Certificate acknowledges
the restrictions on the transfer of such Certificate set forth thereon and
agrees that it will only transfer such a Certificate as provided herein. In
addition, each Holder of a Regulation S Global Security shall be deemed to have
represented and warranted to the Depositor, the Trustee and any of their
respective successors that: (i) such Person is not a "U.S. person" within the
meaning of Regulation S and was, at the time the buy order was originated,
outside the United States and (ii) such Person understands that such
Certificates have not been registered under the Securities Act and that (x)
until the expiration of the 40-day distribution compliance period (within the
meaning of Regulation S), no offer, sale, pledge or other transfer of such
Certificates or any interest therein shall be made in the United States or to or
for the account or benefit of a U.S. person (each as defined in Regulation S),
(y) if in the future it decides to offer, resell, pledge or otherwise transfer
such Certificates, such Certificates may be offered, resold, pledged or
otherwise transferred only (A) to a person which the seller reasonably believes
is a "qualified institutional buyer" as defined in Rule 144A under the
Securities Act, that is purchasing such Certificates for its own account or for
the account of a qualified institutional buyer to which notice is given that the
transfer is being made in reliance on Rule 144A or (B) in an offshore
transaction (as defined in Regulation S) in compliance with the provisions of
Regulation S, in each case in compliance with the requirements of this
Agreement; and it will notify such transferee of the transfer restrictions
specified in this Section.

     No transfer of a Certificate that is neither an ERISA Restricted
Certificate nor a Class R Certificate shall be registered unless the transferee
provides the Trustee with a representation that either (i) such transferee is
not, and is not acting for, on behalf of or with any assets of, an employee
benefit plan or other arrangement subject to Title I of ERISA or plan subject to
Section 4975 of the Code, or (ii) until the termination of the Swap Agreement,
the acquisition and holding of the Certificate are eligible for exemptive relief
under any of Section 408(b)(17) of ERISA or Section 4975(d)(20) of the Code,
Prohibited Transaction Class Exemption ("PTCE") 84-14, PTCE 90-1, PTCE 91-38,
PTCE 95-60 or PTCE 96-23.

     No transfer of an ERISA Restricted Certificate or a Class R Certificate
shall be registered unless the Trustee 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"), and is not directly
or indirectly acquiring the ERISA Restricted Certificate or the Class R
Certificate by, on behalf of, or with any assets of any such plan (collectively,
"Plan"), or (B) solely in the case of ERISA Restricted Certificates, (I) if the
Certificate has been the subject of an ERISA-Qualifying Underwriting, a
representation to the effect that such transferee is an insurance company that
is acquiring the Certificate with assets of 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
an ERISA Restricted Certificate that is a Definitive Certificate, an Opinion of
Counsel satisfactory to the Trustee, and upon which the Trustee and the NIMs
Insurer 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

                                      -121-

<PAGE>

Similar Law, and will not subject the Trustee, the Servicer, the NIMs Insurer 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 Trustee,
the Servicer, the NIMs Insurer or the Depositor.

     Except in the case of a Definitive Certificate, the representations set
forth in the two immediately preceding paragraphs of this Subsection 5.02(a),
other than clause (B)(II) in the immediately preceding paragraph, shall be
deemed to have been made to the Trustee by the transferee's acceptance of a
Certificate (or the acceptance by a Certificate Owner of the beneficial interest
in any Certificate).

     Notwithstanding any other provision herein to the contrary, any purported
transfer of a Certificate to or on behalf of a Plan without the delivery to the
Trustee of a representation or an Opinion of Counsel satisfactory to the Trustee
as described above shall be void and of no effect. The Trustee shall not be
under any liability to any Person for any registration or transfer of any
Certificate that is in fact not permitted by this Section 5.02(a), nor shall the
Trustee 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 Trustee in accordance with the foregoing requirements. The Trustee shall be
entitled, but not obligated, to recover from any Holder of any Certificate that
was in fact a Plan and that held such Certificate in violation of this Section
5.02(a) all payments made on such 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.

          (b) Each Person who has or who acquires any Ownership Interest in a
Class R Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the following provisions, and
the rights of each Person acquiring any Ownership Interest in a Class R
Certificate are expressly subject to the following provisions:

          (i) Each Person holding or acquiring any Ownership Interest in a Class
     R Certificate shall be a Permitted Transferee and shall promptly notify the
     Trustee of any change or impending change in its status as a Permitted
     Transferee.

          (ii) No Ownership Interest in a Class R Certificate may be purchased,
     transferred or sold, directly or indirectly, except in accordance with the
     provisions hereof. No Ownership Interest in a Class R Certificate may be
     registered on the Closing Date or thereafter transferred, and the Trustee
     shall not register the Transfer of any Class R Certificate unless, in
     addition to the certificates required to be delivered to the Trustee under
     subparagraph (a) above, the Trustee shall have been furnished with an
     affidavit (a "Transfer Affidavit") of the initial owner or the proposed
     transferee in the form attached hereto as Exhibit E-1 and an affidavit of
     the proposed transferor in the form attached hereto as Exhibit E-2. In the
     absence of a contrary instruction from the transferor of a Class R
     Certificate, declaration (11) in Appendix A of the Transfer Affidavit may
     be left blank. If the transferor requests by written notice to the Trustee
     prior to the date of the proposed transfer that one of the two other forms
     of declaration (11) in Appendix A of the Transfer Affidavit be used, then
     the requirements of this Section 5.02(b)(ii) shall not have been satisfied
     unless the Transfer Affidavit includes such other form of declaration.

          (iii) Each Person holding or acquiring any Ownership Interest in a
     Class R Certificate shall agree (A) to obtain a Transfer Affidavit from any
     other Person to whom such Person attempts to Transfer its Ownership
     Interest in a Class R Certificate, (B) to obtain a Transfer Affidavit from
     any Person for whom such Person is acting as nominee, trustee or agent in
     connection with any Transfer of a Class R Certificate and (C) not to
     Transfer its Ownership

                                      -122-

<PAGE>

     Interest in a Class R Certificate or to cause the Transfer of an Ownership
     Interest in a Class R Certificate to any other Person if it has actual
     knowledge that such Person is not a Permitted Transferee. Further, no
     transfer, sale or other disposition of any Ownership Interest in a Class R
     Certificate may be made to a person who is not a U.S. Person (within the
     meaning of section 7701 of the Code) unless such person furnishes the
     transferor and the Trustee with a duly completed and effective Internal
     Revenue Service Form W-8ECI (or any successor thereto) and the Trustee
     consents to such transfer, sale or other disposition in writing.

          (iv) Any attempted or purported Transfer of any Ownership Interest in
     a Class R Certificate in violation of the provisions of this Section
     5.02(b) shall be absolutely null and void and shall vest no rights in the
     purported Transferee. If any purported transferee shall become a Holder of
     a Class R Certificate in violation of the provisions of this Section
     5.02(b), then the last preceding Permitted Transferee shall be restored to
     all rights as Holder thereof retroactive to the date of registration of
     Transfer of such Class R Certificate. The Trustee shall be under no
     liability to any Person for any registration of Transfer of a Class R
     Certificate that is in fact not permitted by Section 5.02(a) and this
     Section 5.02(b) or 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
     after receipt of the related Transfer Affidavit. The Trustee shall be
     entitled but not obligated to recover from any Holder of a Class R
     Certificate that was in fact not a Permitted Transferee at the time it
     became a Holder or, at such subsequent time as it became other than a
     Permitted Transferee, all payments made on such Class R Certificate at and
     after either such time. Any such payments so recovered by the Trustee shall
     be paid and delivered by the Trustee to the last preceding Permitted
     Transferee of such Certificate.

          (v) At the option of the Holder of the Class R Certificate, the Class
     SWR Interest, the Class LTR Interest and the residual interest in the Upper
     Tier REMIC may be severed and represented by separate certificates (with
     the separate certificate that represents the Residual Interest also
     representing all rights of the Class R Certificate to distributions
     attributable to an interest rate on the Class R Certificate in excess of
     the REMIC Pass-Through Rate); provided, however, that such separate
     certification may not occur until the Trustee receives an Opinion of
     Counsel to the effect that separate certification in the form and manner
     proposed would not result in the imposition of federal tax upon the Trust
     Fund or any of the REMICs provided for herein or cause any of the REMICs
     provided for herein to fail to qualify as a REMIC; and provided further,
     that the provisions of Sections 5.02(a) and (b) will apply to each such
     separate certificate as if the separate certificate were a Class R
     Certificate. If, as evidenced by an Opinion of Counsel, it is necessary to
     preserve the REMIC status of any of the REMICs provided for herein, the
     Class SWR Interest, the Class LTR Interest and the residual interest in the
     Upper Tier REMIC shall be severed and represented by separate certificates
     (with the separate certificate that represents the Residual Interest also
     representing all rights of the Class R Certificate to distributions
     attributable to an interest rate on the Class R Certificate in excess of
     the REMIC Pass-Through Rate).

     The restrictions on Transfers of a Class R Certificate set forth in this
Section 5.02(b) shall cease to apply (and the applicable portions of the legend
on a Class R Certificate may be deleted) with respect to Transfers occurring
after delivery to the Trustee of an Opinion of Counsel, which Opinion of Counsel
shall not be an expense of the Trustee or the Depositor, to the effect that the
elimination of such restrictions will not cause any of the REMICs provided for
herein to fail to qualify as a REMIC at any time that the Certificates are
outstanding or result in the imposition of any tax on the Issuing Entity, any
REMIC provided for herein, a Certificateholder or another Person. Each Person
holding or acquiring any Ownership Interest in a Class R Certificate hereby
consents to any amendment of this Agreement that,

                                      -123-

<PAGE>

based on an Opinion of Counsel furnished to the Trustee, is reasonably necessary
(a) to ensure that the record ownership of, or any beneficial interest in, a
Class R Certificate is not transferred, directly or indirectly, to a Person that
is not a Permitted Transferee and (b) to provide for a means to compel the
Transfer of a Class R Certificate that is held by a Person that is not a
Permitted Transferee to a Holder that is a Permitted Transferee.

          (c) The transferor of the Class R Certificate shall notify the Trustee
in writing upon the transfer of the Class R Certificate.

          (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 Trustee.

     SECTION 5.03. Mutilated, Destroyed, Lost or Stolen Certificates

     If (a) any mutilated Certificate is surrendered to the Trustee or the
Trustee 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 Trustee such security or indemnity as may be required by them to save each
of them harmless, then, in the absence of notice to the Trustee that such
Certificate has been acquired by a bona fide purchaser, the Trustee 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 Trustee may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto and any other expenses (including the fees and expenses of
the Trustee and its counsel) 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 Trustee under the terms of this Section 5.03
shall be canceled and destroyed by the Trustee in accordance with its standard
procedures without liability on its part.

     SECTION 5.04. Persons Deemed Owners

     The NIMs Insurer, the Trustee and any agent of the NIMs Insurer or the
Trustee may treat the Person in whose name any Certificate is registered as the
owner of such Certificate for the purpose of receiving distributions as provided
in this Agreement and for all other purposes whatsoever, and neither the NIMs
Insurer nor the Trustee, nor any agent of the NIMs Insurer or the Trustee, 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 Trustee, (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 NIMs Insurer or the Depositor
shall request such information in writing from the Trustee, then the Trustee
shall, within ten Business Days after the receipt of such request, provide the
NIMs Insurer or the Depositor or such Certificateholders at such recipients'
expense the most recent list of the Certificateholders of the Issuing Entity
held by the Trustee, if any. The Depositor and every Certificateholder, by
receiving and holding a Certificate, agree that the Trustee shall

                                      -124-

<PAGE>

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 Class C, Class P and Class R Certificates shall be definitive
certificates. 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):

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

          (b) the Depositor, the NIMs Insurer and the Trustee may deal with the
Depository and the Depository Participants for all purposes (including the
making of 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 Trustee 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 Trustee 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.

     In the event that Definitive Certificates are issued pursuant to Section
5.08(b), clauses (a) through (g) of this Section 5.06 shall continue to be
applicable with respect to all remaining Book-Entry Certificates.

     SECTION 5.07. Notices to Depository

                                      -125-

<PAGE>

     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 Trustee shall give all such
notices and communications to the Depository.

     SECTION 5.08. Definitive Certificates

     (a) If, after Book-Entry Certificates have been issued with respect to any
Certificates, (a) the Depository or the Depositor advises the Trustee 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 Trustee or the Depositor is unable to locate a qualified
successor, (b) the Depositor notifies the Trustee 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 evidenced
by any Class of Book-Entry Certificates advise the Trustee 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 Trustee shall notify all Certificate
Owners of such Book-Entry Certificates and the NIMs Insurer, 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 Trustee with an adequate inventory of
certificates to facilitate the issuance and transfer of Definitive Certificates.
Upon surrender to the Trustee of any such Certificates by the Depository,
accompanied by registration instructions from the Depository for registration,
the Authenticating Agent shall authenticate and the Trustee shall deliver such
Definitive Certificates. Neither the Depositor nor the Trustee 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 Trustee, to the extent applicable with respect to such
Definitive Certificates and the Trustee shall recognize the Holders of such
Definitive Certificates as Certificateholders hereunder.

     SECTION 5.09. Maintenance of Office or Agency

     The Trustee 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 Trustee initially designates its
offices at 135 South LaSalle Street, Suite 1511, Chicago, Illinois 60603,
Attention: Global Securities and Trust Services MLMI 2006-HE6 as offices for
such purposes. The Trustee will give prompt written notice to the
Certificateholders of any change in such location of any such office or agency.

     SECTION 5.10. Authenticating Agents

     (a) One or more Authenticating Agents (each, an "Authenticating Agent") may
be appointed hereunder each of which shall be authorized to act on behalf of the
Trustee in authenticating the Certificates. Wherever reference is made in this
Agreement to the authentication of Certificates by the Trustee's certificate of
authentication, such reference shall be deemed to include authentication on
behalf of the Trustee by an Authenticating Agent and a certificate of
authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent must be an entity organized and doing business under
the laws of the United States of America or any state thereof, having a combined
capital

                                      -126-

<PAGE>

and surplus of at least $15,000,000, authorized under such laws to operate a
trust business and subject to supervision or examination by federal or state
authorities. If the Authenticating Agent is a party other than the Trustee, the
Trustee shall have no liability in connection with the performance or failure of
performance of the Authenticating Agent. LaSalle Bank National Association is
hereby appointed as the initial Authenticating Agent. The Trustee shall be the
Authenticating Agent during any such time as no other Authenticating Agent has
been appointed and has not resigned.

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

     (c) Any Authenticating Agent may at any time resign by giving at least 30
days' advance written notice of resignation to the Trustee and the Depositor.
Except with respect to the initial Authenticating Agent, LaSalle Bank National
Association, which shall be the Authenticating Agent for so long as it is the
Trustee may at any time terminate the agency of any Authenticating Agent by
giving written notice of termination to such Authenticating Agent and the
Depositor. Upon receiving a notice of resignation or upon such a termination, or
in case at any time any Authenticating Agent shall cease to be eligible in
accordance within the provisions of this Section 5.10, the Trustee may appoint a
successor Authenticating Agent, shall give written notice of such appointment to
the Depositor and shall mail notice of such appointment to all Holders of
Certificates. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers, duties
and responsibilities of its predecessor hereunder, with like effect as if
originally named as Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section 5.10. No
Authenticating Agent shall have responsibility or liability for any action taken
by it as such at the direction of the Trustee.

                                   ARTICLE VI

                         THE DEPOSITOR AND THE SERVICER

     SECTION 6.01. Respective Liabilities of the Depositor and the Servicer

     The Depositor and the Servicer shall each be liable in accordance herewith
only to the extent of the obligations specifically and respectively imposed upon
and undertaken by them herein.

     SECTION 6.02. Merger or Consolidation of the Depositor or the Servicer

     Except as provided in the next paragraph, the Depositor and the Servicer
will each keep in full effect its existence, rights and franchises as a
corporation or banking association under the laws of the United States or under
the laws of one of the States thereof and will each obtain and preserve its
qualification to do business as a foreign corporation in each jurisdiction in
which such qualification is or shall be necessary to protect the validity and
enforceability of this Agreement, or any of the Mortgage Loans and to perform
its respective duties under this Agreement.

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

                                      -127-

<PAGE>

(except for the execution of an assumption agreement where such succession is
not effected by operation of law); provided, however, that the successor or
surviving Person to the Servicer shall be qualified to sell mortgage loans to,
and to service mortgage loans on behalf of, Fannie Mae or Freddie Mac.

     SECTION 6.03. Limitation on Liability of the Depositor, the Servicer and
Others

     None of the Depositor, the Servicer or any of the directors, officers,
employees or agents of the Depositor or the Servicer shall be under any
liability to the Issuing Entity or the Certificateholders for any action taken
or for refraining from the taking of any action in good faith pursuant to this
Agreement, or for errors in judgment; provided, however, that this provision
shall not protect the Depositor, the Servicer or any such Person against any
breach of representations or warranties made by it herein or protect the
Depositor, the Servicer or any such Person from any liability that would
otherwise be imposed by reasons of willful misfeasance, bad faith or negligence
in the performance of duties or by reason of reckless disregard of obligations
and duties hereunder. The Depositor or the Servicer and any director, officer,
employee or agent of the Depositor or the Servicer may rely in good faith on any
document of any kind prima facie properly executed and submitted by any Person
respecting any matters arising hereunder. The Depositor or the Servicer and any
director, officer, employee or agent of the Depositor or the Servicer shall be
indemnified by the Issuing Entity and held harmless against any loss, liability
or expense, incurred in connection with the performance of their duties under
this Agreement or incurred in connection with any audit, controversy or judicial
proceeding relating to a governmental taxing authority or any legal action
relating to this Agreement or the Certificates, other than any loss, liability
or expense (i) incurred by reason of willful misfeasance, bad faith or
negligence in the performance of duties hereunder or by reason of reckless
disregard of obligations and duties hereunder or (ii) which does not constitute
an "unanticipated expense" within the meaning of Treasury Regulation Section
1.860G-1(b)(3)(ii). Neither the Depositor nor the Servicer shall be under any
obligation to appear in, prosecute or defend any legal action that is not
incidental to its respective duties hereunder and that in its opinion may
involve it in any expense or liability; provided, however, that any either of
the Depositor or the Servicer in its discretion may undertake any such action
that it may deem necessary or desirable in respect of this Agreement and the
rights and duties of the parties hereto and the interests of the Trustee and 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 Depositor and the Servicer shall be
entitled to be reimbursed therefor out of the Collection Account as provided by
Section 3.08 hereof.

     The provisions of this Section 6.03 shall survive any termination of this
Agreement and the resignation or removal of the Depositor or the Servicer and
shall be construed to include, but not be limited to any loss, liability or
expense under any environmental law.

     Notwithstanding anything herein to the contrary, in preparing or furnishing
any reports or certifications pursuant to this Agreement, the Servicer shall be
entitled to rely conclusively on the accuracy of the information or data
provided to it by any other party to the Agreement and shall have no liability
for any errors therein.

     SECTION 6.04. Limitation on Resignation of Servicer

     Subject to the provisions of Section 7.01, the second paragraph of Section
7.02, the second paragraph of Section 6.02 and the following paragraph of this
Section 6.04, the Servicer shall not resign from the obligations and duties
hereby imposed on it except upon determination that its duties hereunder are no
longer permissible under applicable law. Any such determination permitting the
resignation of the Servicer shall be evidenced by an Opinion of Counsel to such
effect delivered to the Trustee and the

                                      -128-

<PAGE>

NIMs Insurer. No such resignation shall become effective until the Trustee or a
successor servicer reasonably acceptable to the NIMs Insurer and the Trustee is
appointed and has assumed the Servicer's responsibilities, duties, liabilities
and obligations hereunder. Any such resignation shall not relieve the Servicer
of any of the obligations specified in Section 7.01 and 7.02 as obligations that
survive the resignation or termination of the Servicer.

     Notwithstanding anything to the contrary in the previous paragraph of this
Section 6.04, the Trustee, the Depositor and the NIMs Insurer hereby
specifically (i) consent to the pledge and assignment by the Servicer of all the
Servicer's right, title and interest in, to and under this Agreement to the
Servicing Rights Pledgee, if any, for the benefit of certain lenders, and (ii)
agree that upon delivery to the Trustee by the Servicing Rights Pledgee of a
letter signed by the Servicer whereby the Servicer shall resign as Servicer
under this Agreement, notwithstanding anything to the contrary which may be set
forth in Section 3.04 above, the Trustee shall appoint the Servicing Rights
Pledgee or its designee as successor servicer, provided that the Servicer's
resignation will not be effective unless, at the time of such appointment, the
Servicing Rights Pledgee or its designee (i) meets the requirements of a
successor servicer under Section 7.03 of this Agreement (including being
acceptable to the Rating Agencies), provided, that the consent and approval of
the Trustee, the Depositor and the NIMS Insurer shall be deemed to have been
given to the Servicing Rights Pledgee or its designee, and the Servicing Rights
Pledgee and its designee are hereby agreed to be acceptable to the Trustee, the
Depositor and the NIMS Insurer and (ii) agrees to be subject to the terms of
this Agreement. If, pursuant to any provision hereof, the duties of the Servicer
are transferred to a successor servicer, the entire amount of the Servicing Fee
and other compensation payable to the Servicer pursuant hereto shall thereafter
be payable to such successor servicer.

     SECTION 6.05. Errors and Omissions Insurance; Fidelity Bonds

     The Servicer shall, for so long as it acts as servicer under this
Agreement, obtain and maintain in force (a) a policy or policies of insurance
covering errors and omissions in the performance of its obligations as servicer
hereunder, and (b) a fidelity bond in respect of its officers, employees and
agents. Each such policy or policies and bond shall, together, comply with the
requirements from time to time of Fannie Mae or Freddie Mac for Persons
performing servicing for mortgage loans purchased by Fannie Mae or Freddie Mac.
The Servicer shall provide the Trustee and the NIMs Insurer, upon request and
reasonable notice, with copies of such policies and fidelity bond or a
certification from the insurance provider evidencing such policies and fidelity
bond. The Servicer may be deemed to have complied with this provision if an
Affiliate of the Servicer has such errors and omissions and fidelity bond
coverage and, by the terms of such insurance policy or fidelity bond, the
coverage afforded thereunder extends to the Servicer. In the event that any such
policy or bond ceases to be in effect, the Servicer shall use its reasonable
best efforts to obtain a comparable replacement policy or bond from an insurer
or issuer meeting the requirements set forth above as of the date of such
replacement. Any such policy or fidelity bond shall by its terms not be
cancelable without thirty days' prior written notice to the Trustee.

                                   ARTICLE VII

                        DEFAULT; TERMINATION OF SERVICER

     SECTION 7.01. Events of Default

     "Event of Default," wherever used herein, means any one of the following
events:

          (i) any failure by the Servicer to make any Advance, to deposit in the
     Collection Account or the Certificate Account or remit to the Trustee any
     payment (excluding a payment

                                      -129-

<PAGE>

     required to be made under Section 4.01 hereof) required to be made under
     the terms of this Agreement, which failure shall continue unremedied for
     three Business Days and, with respect to a payment required to be made
     under Section 4.01 hereof, for one Business Day, after the date on which
     written notice of such failure shall have been given to the Servicer by the
     Trustee or the Depositor, or to the Trustee, the Depositor and the Servicer
     by the NIMs Insurer or the Holders of Certificates evidencing greater than
     50% of the Voting Rights evidenced by the Certificates; or

          (ii) any failure by the Servicer to observe or perform in any material
     respect any other of the covenants or agreements on the part of the
     Servicer contained in this Agreement or any representation or warranty
     shall prove to be untrue, which failure or breach shall continue unremedied
     for a period of 60 days after the date on which written notice of such
     failure shall have been given to the Servicer, the Trustee and the
     Depositor by the Trustee or the Depositor, or to the Servicer, the Trustee
     and the Depositor by the Holders of Certificates evidencing greater than
     50% of the Voting Rights evidenced by the Certificates; or

          (iii) a decree or order of a court or agency or supervisory authority
     having jurisdiction for the appointment of a 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,
     shall have been entered against the Servicer and such decree or order shall
     have remained in force undischarged or unstayed for a period of 60
     consecutive days; or

          (iv) consent by the Servicer to the appointment of a receiver or
     liquidator in any insolvency, readjustment of debt, marshaling of assets
     and liabilities or similar proceedings of or relating to the Servicer or
     all or substantially all of the property of the Servicer; or

          (v) admission by the Servicer in writing of its inability to pay its
     debts generally as they become due, file a petition to take advantage of,
     or commence a voluntary case under, any applicable insolvency or
     reorganization statute, make an assignment for the benefit of its
     creditors, or voluntarily suspend payment of its obligations; or

          (vi) any failure by the Servicer to duly perform, within the required
     time period, its obligations under Sections 3.17, 3.18 and 3.22 of this
     Agreement, which failure continues unremedied for a period of ten (10) days
     after the date on which written notice of such failure, requiring the same
     to be remedied, shall have been given to the Servicer by the Trustee or any
     other party to this Agreement.

     If an Event of Default shall occur with respect to the Servicer, then, and
in each and every such case, so long as such Event of Default shall not have
been remedied within the applicable grace period, the Trustee may, or at the
direction of the NIMs Insurer or the Holders of Certificates evidencing greater
than 50% of the Voting Rights evidenced by the Certificates (with the written
consent of the NIMs Insurer, except after a NIMs Insurer Default), shall, by
notice in writing to the Servicer (with a copy to each Rating Agency), terminate
all of the rights and obligations of the Servicer under this Agreement and in
and to the related Mortgage Loans and the proceeds thereof, other than its
rights as a Certificateholder hereunder. On or after the receipt by the Servicer
of such written notice, all authority and power of the Servicer hereunder,
whether with respect to the related Mortgage Loans or otherwise, shall pass to
and be vested in the Trustee. To the extent the Event of Default resulted from
the failure of the Servicer to make a required Advance, the Trustee shall
thereupon make any Advance described in Section 4.01 hereof subject to Section
3.04 hereof. The Trustee is hereby authorized and empowered to execute and
deliver, on behalf of the Servicer, as attorney-in-fact or otherwise, any and
all documents and other instruments, and to do or accomplish all other acts or
things necessary or appropriate to effect the purposes of such

                                      -130-

<PAGE>

notice of termination, whether to complete the transfer and endorsement or
assignment of the Mortgage Loans and related documents, or otherwise. Unless
expressly provided in such written notice, no such termination shall affect any
obligation of the Servicer to pay amounts owed pursuant to Article VIII. The
Servicer agrees to cooperate with the Trustee in effecting the termination of
the Servicer's responsibilities and rights hereunder, including, without
limitation, the transfer to the Trustee of all cash amounts which shall at the
time be credited to the Collection Account, or thereafter be received with
respect to the Mortgage Loans. The Servicer and the Trustee shall promptly
notify the Rating Agencies of the occurrence of an Event of Default, such notice
to be provided in any event within two Business Days of such occurrence.

     Notwithstanding any termination of the activities of the Servicer
hereunder, the Servicer shall be entitled to receive, out of any late collection
of a Scheduled Payment on a Mortgage Loan that was due prior to the notice
terminating the Servicer's rights and obligations as Servicer hereunder and
received after such notice, that portion thereof to which the Servicer would
have been entitled pursuant to Section 3.08(a), and any other amounts payable to
the Servicer hereunder the entitlement to which arose prior to the termination
of its activities hereunder. Notwithstanding anything herein to the contrary,
upon termination of the Servicer hereunder, any liabilities of the Servicer
which accrued prior to such termination shall survive such termination.

     SECTION 7.02. Trustee to Act; Appointment of Successor

     On and after the time the Servicer receives a notice of termination
pursuant to Section 7.01 hereof, the Trustee shall, to the extent provided in
Section 3.04, be the successor to the Servicer in its capacity as servicer under
this Agreement and the transactions set forth or provided for herein and shall
be subject to all the responsibilities, duties and liabilities relating thereto
placed on the Servicer by the terms and provisions hereof and applicable law
including the obligation to make advances pursuant to Section 4.01. As
compensation therefor, subject to the last paragraph of Section 7.01, the
Trustee shall be entitled to all fees, compensation and reimbursement for costs
and expenses that the Servicer would have been entitled to hereunder if the
Servicer had continued to act hereunder. Notwithstanding the foregoing, if the
Trustee has become the successor to the Servicer in accordance with Section 7.01
hereof, the Trustee may, if it shall be unwilling to so act, or shall, if it is
prohibited by applicable law from making Advances pursuant to Section 4.01
hereof or if it is otherwise unable to so act, appoint, or petition a court of
competent jurisdiction to appoint, any established mortgage loan servicing
institution provided the appointment of such successor shall be approved by the
NIMs Insurer and does not adversely affect the then current rating of the
Certificates by each Rating Agency as the successor to the Servicer hereunder in
the assumption of all or any part of the responsibilities, duties or liabilities
of the Servicer hereunder. Any successor Servicer shall be an institution that
is acceptable to the NIMs Insurer and is a Fannie Mae and Freddie Mac approved
seller/servicer in good standing, that has a net worth of at least $15,000,000,
and that is willing to service the Mortgage Loans and executes and delivers to
the Depositor and the Trustee an agreement accepting such delegation and
assignment, that contains an assumption by such Person of the rights, powers,
duties, responsibilities, obligations and liabilities of the Servicer (other
than liabilities of the Servicer under Section 6.03 hereof incurred prior to
termination of the Servicer under Section 7.01), with like effect as if
originally named as a party to this Agreement; and provided further that each
Rating Agency acknowledges that its rating of the Certificates in effect
immediately prior to such assignment and delegation will not be qualified or
reduced as a result of such assignment and delegation. No appointment of a
successor to the Servicer hereunder shall be effective until the Trustee shall
have consented thereto, prior written consent of the NIMs Insurer is obtained
(provided, that such prior written consent shall not be required in the event
that the Servicing Rights Pledgee or its designee is so appointed as successor
servicer) and written notice of such proposed appointment shall have been
provided by the Trustee to each Certificateholder. The Trustee shall not resign
as servicer until a

                                      -131-

<PAGE>

successor servicer has been appointed and has accepted such appointment. Pending
appointment of a successor to the Servicer hereunder, the Trustee, unless the
Trustee is prohibited by law from so acting, shall, subject to Section 3.04
hereof, 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 Mortgage Loans as it and such
successor shall agree; provided, however, that no such compensation shall be in
excess of that permitted the Servicer hereunder. The Trustee and such successor
shall take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession. Neither the Trustee nor any other successor
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 by the failure of the Servicer
to deliver or provide, or any delay in delivering or providing, any cash,
information, documents or records to it.

     Any successor to the Servicer as servicer shall give notice to the
Mortgagors of such change of servicer and shall, during the term of its service
as servicer maintain in force the policy or policies that the Servicer is
required to maintain pursuant to Section 6.05.

     SECTION 7.03. Notification to Certificateholders

          (a) Upon any termination of or appointment of a successor to the
Servicer, the Trustee shall give prompt written notice thereof to
Certificateholders, the Depositor, the Swap Counterparty and to each Rating
Agency.

          (b) Within 60 days after the occurrence of any Event of Default, the
Trustee shall transmit by mail to all Certificateholders and the Rating Agencies
notice of each such Event of Default hereunder known to the Trustee, unless such
Event of Default shall have been cured or waived.

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

     SECTION 8.01. Duties of the Trustee

     For purposes of this Article VIII, references to "Trustee" shall be deemed

curing of all Events of Default that may have occurred, shall undertake to
perform such duties and only such duties as are specifically set forth in this
Agreement. In case an Event of Default has occurred and remains uncured, the
Trustee shall exercise such of the rights and powers vested in it by this
Agreement and use the same degree of care and skill in its exercise as a prudent
person would exercise or use under the circumstances in the conduct of such
person's own affairs. In case an Event of Default or other default by the
Servicer or the Depositor hereunder shall occur and be continuing, the Trustee
shall, at the written direction of the majority of the Certificateholders or the
NIMs Insurer, or may, proceed to protect and enforce its rights and the rights
of the Certificateholders or the NIMs Insurer under this Agreement by a suit,
action or proceeding in equity or at law or otherwise, whether for the specific
performance of any covenant or agreement contained in this agreement or in aid
of the execution of any power granted in this Agreement or for the enforcement
of any other legal, equitable or other remedy, as the Trustee, being advised by

                                      -132-

counsel and subject to the foregoing, shall deem most effectual to protect and
enforce any of the rights of the Trustee, the NIMs Insurer and the
Certificateholders.

     The Trustee, upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments furnished to the
Trustee that are specifically required to be furnished pursuant to any provision
of this Agreement, shall examine them to determine whether they conform on their
face to the requirements of this Agreement. If any such instrument is found not
to conform on its face to the requirements of this Agreement in a material
manner, the Trustee shall notify the person providing such Agreement of such
non-conformance, and if the instrument is not corrected to the its satisfaction,
the Trustee will provide notice thereof to the Certificateholders and the NIMs
Insurer and take such further action as directed by the Certificateholders and
the NIMs Insurer.

     No provision of this Agreement shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or
its own misconduct, its negligent failure to perform its obligations in
compliance with this Agreement, or any liability that would be imposed by reason
of its willful misfeasance or bad faith; provided, however, that:

          (i) prior to the occurrence of an Event of Default, and after the
     curing of all such Events of Default that may have occurred, the duties and
     obligations of the Trustee shall be determined solely by the express
     provisions of this Agreement, the Trustee shall not be liable, individually
     or as Trustee, except for the performance of such duties and obligations as
     are specifically set forth in this Agreement, no implied covenants or
     obligations shall be read into this Agreement against the Trustee and, the
     Trustee may conclusively rely, as to the truth of the statements and the
     correctness of the opinions expressed therein, upon any certificates or
     opinions furnished to the Trustee and conforming to the requirements of
     this Agreement that it reasonably believed in good faith to be genuine and
     to have been duly executed by the proper authorities respecting any matters
     arising hereunder;

          (ii) the Trustee shall not, individually or as Trustee, be liable for
     an error of judgment made in good faith by a Responsible Officer or
     Responsible Officers of the Trustee unless the Trustee was negligent or
     acted in bad faith or with willful misfeasance;

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

          (iv) the Trustee shall not be responsible for the acts or omissions of
     any servicer or subservicer, it being understood that this Agreement shall
     not be construed to render any of them agents of one another.

     opinion, report, notice, request, consent, order, approval, bond or other
     paper or document, unless requested in writing so to do by the NIMs Insurer

     of the Voting Rights of such Class;

     part of any other agent, custodian, accountant, attorney or independent
     contractor appointed with due care by it hereunder;

          (vi) the Trustee shall not be required to expend its own funds or

     duties hereunder if it shall have reasonable grounds for believing that
     repayment of such funds or adequate indemnity against such liability is not
     assured to it;

     any loss on any investment of funds pursuant to this Agreement (other than

     defend any litigation hereunder or in relation hereto at the request, order
     or direction of any of the NIMs Insurer or the Certificateholders, pursuant
     to the provisions of this Agreement, unless the NIMs Insurer or such
     Certificateholders shall have offered to the Trustee reasonable security or
     indemnity satisfactory to it against the costs, expenses and liabilities
     that may be incurred therein or thereby;

          (x) if requested by the Servicer, the Trustee may appoint the Servicer

responsibility for their correctness. The Trustee makes no representation as to
the validity or sufficiency of this Agreement, of any Mortgage Loan, or any
related document other than with respect to the execution and authentication of
the Certificates, if it so executed or authorized the Certificates. The Trustee
shall not be accountable for the use or application by the Depositor or the

     SECTION 8.04. Trustee May Own Certificates

pledgee of Certificates with the same rights as it would have if it was not the
Trustee.

     SECTION 8.05. Trustee's Fees and Expenses

     The Trustee and any custodian shall be entitled to, such compensation as
shall be agreed to in writing by the Trustee and the Depositor (which shall not

hereby created and in the exercise and performance of any of the powers and
duties hereunder of the Trustee.

     SECTION 8.06. Indemnification and Expenses of Trustee

          (a) LaSalle Bank National Association (as Trustee and in its
individual corporate capacity) and its directors, officers, employees and agents
shall be entitled to indemnification from the Issuing Entity for any loss,
liability or expense incurred in connection with (i) any audit, controversy or

                                      -135-

<PAGE>

judicial proceeding relating to a governmental authority or any legal proceeding
incurred without negligence or willful misconduct on their part, arising out of,
or in connection with the acceptance or administration of the trusts created
hereunder and (ii) the performance of their duties hereunder, including any
applicable fees and expenses payable hereunder, and the costs and expenses of
defending themselves against any claim in connection with the exercise or
performance of any of their powers or duties hereunder, provided that:

          (i) with respect to any such claim, the Trustee shall have given the
     Depositor written notice thereof promptly after the Trustee shall have
     knowledge thereof; provided that failure to so notify shall not relieve the
     Issuing Entity of the obligation to indemnify the Trustee; however, any
     reasonable delay by the Trustee to provide written notice to the Depositor
     and the Holders promptly after the Trustee shall have obtained knowledge of
     a claim shall not relieve the Issuing Entity of the obligation to indemnify
     the Trustee under this Section 8.06;

          (ii) while maintaining control over its own defense, the Trustee shall
     reasonably cooperate and consult with the Depositor in preparing such
     defense;

          (iii) notwithstanding anything to the contrary in this Section 8.06,
     the Issuing Entity shall not be liable for settlement of any such claim by
     the Trustee entered into without the prior consent of the Depositor, which
     consent shall not be unreasonably withheld or delayed; and

          (iv) indemnification therefor would constitute "unanticipated
     expenses" within the meaning of Treasury Regulation Section
     1.860G-1(b)(3)(ii).

     Any indemnification payments to the Trustee (or a custodian) pursuant to
this Section 8.06(a) shall be allocated first to principal and then, to the
extent remaining, to interest.

          (b) The Trustee shall be entitled to reimbursement by the Issuing
Entity of all reasonable expenses, disbursements and advances incurred or made
by the Trustee in accordance with this Agreement (including fees and expenses of
its counsel and all persons not regularly in its employment), except any such
expenses, disbursements and advances that either (i) arise from its negligence,
bad faith or willful misconduct or (ii) do not constitute "unanticipated
expenses" within the meaning of Treasury Regulations Section 1.860G-1(b)(3)(ii).

          (c) The Trustee's right to indemnification and reimbursement shall be
subject to a cap of $400,000 in the aggregate in any calendar year, excluding
(i) any Servicing Transfer Costs and (ii) any costs, damages or expenses
incurred by the Trustee in connection with any "high cost" home loans or any
predatory or abusive lending laws, which amounts shall in no case be subject to
any such limitation; provided, however, that such cap shall apply only if NIM
Notes have been issued and there is a NIMs Insurer and shall cease to apply
after the date on which any NIM Notes are paid in full or if there is no NIMs
Insurer; provided further, however, that amounts incurred by the Trustee in
excess of such annual limit in any calendar year shall be payable to the Trustee
in succeeding calendar years, subject to such annual limit for each applicable
calendar year. Any amounts reimbursable hereunder not in excess of this cap may
be withdrawn by the Trustee from the Certificate Account at any time.

          (d) Any custodian appointed by the Trustee as herein provided shall be
entitled to indemnification and reimbursement of expenses to the same extent as
the Trustee is entitled to such amounts pursuant to subsection (a) and (b) of
this Section 8.06, without regard to subsection (c) of this Section 8.06.

                                     -136-

<PAGE>

          (e) The provisions of this Section 8.06 shall survive any termination
of this Agreement and the resignation or removal of the Trustee or the custodian
and shall be construed to include, but not be limited to any loss, liability or
expense under any environmental law.

     SECTION 8.07. Eligibility Requirements for Trustee

     The Trustee hereunder shall, at all times, be a corporation or association
organized and doing business under the laws of a state or the United States of
America, authorized under such laws to exercise corporate trust powers having a
combined capital and surplus of at least $50,000,000, subject to supervision or
examination by federal or state authority and with a long-term deposit rating of
at least "A2" by Moody's and "A" by S&P and any successor trustee appointed
pursuant to Section 8.08 of this Agreement shall have a short-term S&P rating of
at least "A-1". If such corporation or association publishes reports of
condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section 8.07 the combined capital and surplus of such corporation or association
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. In case at any time the Trustee shall
cease to be eligible in accordance with the provisions of this Section 8.07, the
Trustee shall resign immediately in the manner and with the effect specified in
Section 8.08 hereof. The corporation or national banking association serving as
Trustee may have normal banking and trust relationships with the Depositor, the
NIMs Insurer and their respective Affiliates; provided, however, that such
corporation cannot be an Affiliate of the Servicer.

     SECTION 8.08. Resignation and Removal of Trustee

     The Trustee may at any time resign and be discharged from the trusts hereby
created by (1) giving written notice of resignation to the Depositor and by
mailing notice of resignation by first class mail, postage prepaid, to the
Certificateholders at their addresses appearing on the Certificate Register and
each Rating Agency, not less than 60 days before the date specified in such
notice when, subject to Section 8.09, such resignation is to take effect, and
(2) acceptance of appointment by a successor trustee acceptable to the NIMs
Insurer in accordance with Section 8.09 and meeting the qualifications set forth
in Section 8.07. If no successor trustee shall have been so appointed and have
accepted appointment within 30 days after the giving of such notice or
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee.

     If at any time (i) the Trustee shall cease to be eligible in accordance
with the provisions of Section 8.07 hereof and shall fail to resign after
written request thereto by the Depositor or the NIMs Insurer or (ii) the Trustee
shall become incapable of acting, or shall be adjudged as bankrupt or insolvent,
or a receiver of the Trustee or of its property shall be appointed, or any
public officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, then the
Depositor may remove the Trustee and shall promptly appoint a successor trustee
by written instrument, in triplicate, one copy of which instrument shall be
delivered to the Trustee and one copy of which shall be delivered to the
successor trustee.

     The Holders evidencing at least 51% of the Voting Rights of all Classes of
Certificates, with the consent of the NIMs Insurer, or the NIMs Insurer upon
failure of the Trustee to perform its obligations hereunder, may at any time
remove the Trustee and the Depositor shall appoint a successor trustee by
written instrument or instruments, in triplicate, signed by such Holders or
their attorneys-in-fact duly authorized (or by the NIMs Insurer), one complete
set of which instruments shall be delivered by the successor trustee to the
Servicer, one complete set to the Trustee so removed and one complete set to the

                                      -137-

<PAGE>

successor so appointed. Notice of any removal of the Trustee shall be given to
the NIMs Insurer and each Rating Agency by the successor trustee.

     Any resignation or removal of the Trustee and appointment of a successor
trustee pursuant to any of the provisions of this Section 8.08 shall become
effective upon acceptance of appointment by the successor trustee as provided in
Section 8.09 hereof.

     SECTION 8.09. Successor Trustee

     Any successor trustee appointed as provided in Section 8.08 hereof shall
execute, acknowledge and deliver to the Depositor and to its predecessor
trustee, the NIMs Insurer and the Servicer an instrument accepting such
appointment hereunder and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become fully vested with all the
rights, powers, duties and obligations of its predecessor hereunder, with like
effect as if originally named as trustee herein.

     No successor trustee shall accept appointment as provided in this Section
8.09 unless at the time of such acceptance such successor trustee shall be
eligible under the provisions of Section 8.07 hereof and its appointment shall
not adversely affect the then current rating of the Certificates.

     Upon acceptance of appointment by a successor trustee as provided in this
Section 8.09, the Depositor shall mail notice of the succession of such trustee
hereunder to all Holders of Certificates. If the Depositor fails to mail such
notice within ten days after acceptance of appointment by the successor trustee,
the successor trustee shall cause such notice to be mailed at the expense of the
Depositor.

     SECTION 8.10. Merger or Consolidation of Trustee

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided that such corporation shall be eligible under the provisions of Section
8.07 hereof without the execution or filing of any paper or further act on the
part of any of the parties hereto, anything herein to the contrary
notwithstanding (except for the execution of an assumption agreement where such
succession is not effected by operation of law).

     SECTION 8.11. Appointment of Co-Trustee or Separate Trustee

     Notwithstanding any other provisions of this Agreement, at any time, for
the purpose of meeting any legal requirements of any jurisdiction in which any
part of the Trust Fund or property securing any Mortgage Note may at the time be
located, the Servicer and the Trustee acting jointly shall have the power and
shall execute and deliver all instruments to appoint one or more Persons
approved by the Trustee and the NIMs Insurer to act as co-trustee or co-trustees
jointly with the Trustee, or separate trustee or separate trustees, of all or
any part of the Trust Fund, and to vest in such Person or Persons, in such
capacity and for the benefit of the Certificateholders, such title to the Trust
Fund or any part thereof, whichever is applicable, and, subject to the other
provisions of this Section 8.11, such powers, duties, obligations, rights and
trusts as the Servicer and the Trustee may consider necessary or desirable. Any
such co-trustee or separate trustee shall be compensated by the Trust Fund and
subject to the written approval of the Servicer and the NIMs Insurer. The
Trustee shall not be liable for the actions of any co-trustee appointed with due
care; provided that the appointment of a co-trustee shall not relieve the
Trustee of its obligations hereunder. If the Servicer and the NIMs Insurer shall
not have joined in such

                                     -138-

<PAGE>

appointment within 15 days after the receipt by it of a request to do so, or in
the case an Event of Default shall have occurred and be continuing, the Trustee
alone shall have the power to make such appointment. No co-trustee or separate
trustee hereunder shall be required to meet the terms of eligibility as a
successor trustee under Section 8.07 and no notice to Certificateholders of the
appointment of any co-trustee or separate trustee shall be required under
Section 8.09.

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

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

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

          (iii) The Trustee, with the consent of the NIMs Insurer, may at any
     time accept the resignation of or remove any separate trustee or
     co-trustee.

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

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

     SECTION 8.12. Tax Matters

          (a) It is intended that each of the REMICs provided for herein shall
constitute, and that the affairs of the Trust Fund shall be conducted so as to
allow each such REMIC to qualify as, a "real estate mortgage investment conduit"
as defined in and in accordance with the REMIC Provisions. It is also intended
that each of the grantor trusts provided for in Section 2.07 hereof shall
constitute, and that the affairs of the Trust Fund shall be conducted so as to
allow each such grantor trust to qualify as, a grantor trust under the
provisions of Subpart E, Part I of Subchapter J of the Code. In furtherance of
such

                                     -139-

<PAGE>

intention, the Trustee covenants and agrees that it shall act as agent (and the

provided for herein and that in such capacity it shall: (a) prepare and file, or
cause to be prepared and filed, in a timely manner, a U.S. Real Estate Mortgage

filed with the Internal Revenue Service and applicable state or local tax
authorities income tax or information returns for each taxable year with respect
to each of the REMICs and grantor trusts provided for herein, containing such
information and at the times and in the manner as may be required by the Code or
state or local tax laws, regulations, or rules, and furnish or cause to be
furnished to Certificateholders the schedules, statements or information at such
times and in such manner as may be required thereby; (b) within thirty days of
the Closing Date, furnish or cause to be furnished to the Internal Revenue
Service, on Forms 8811 or as otherwise may be required by the Code, the name,
title, address, and telephone number of the person that the holders of the
Certificates may contact for tax information relating thereto, together with
such additional information as may be required by such Form, and update such
information at the time or times in the manner required by the Code for each of
the REMICs provided for herein; (c) make or cause to be made elections, on
behalf of each of the REMICs provided for herein to be treated as a REMIC on the
federal tax return of such REMICs for their first taxable years (and, if
necessary, under applicable state law); (d) prepare and forward, or cause to be
prepared and forwarded, to the Certificateholders and to the Internal Revenue
Service and, if necessary, state tax authorities, all information returns and
reports as and when required to be provided to them in accordance with the REMIC
Provisions or other applicable law, including without limitation, the
calculation of any original issue discount using the Prepayment Assumption; (e)
provide information necessary for the computation of tax imposed on the transfer
of a Class R Certificate to a Person that is not a Permitted Transferee, or an
agent (including a broker, nominee or other middleman) of a Person that is not a
Permitted Transferee, or a pass through entity in which a Person that is not a
Permitted Transferee is the record holder of an interest (the reasonable cost of
computing and furnishing such information may be charged to the Person liable
for such tax); (f) to the extent that they are under its control conduct the
affairs of each of the REMICs and grantor trusts provided for herein at all
times that any Certificates are outstanding so as to maintain the status of each
of the REMICs provided for herein as a REMIC under the REMIC Provisions and the
status of each of the grantor trusts provided for herein as a grantor trust
under Subpart E, Part I of Subchapter J of the Code; (g) not knowingly or
intentionally take any action or omit to take any action that would cause the
termination of the REMIC status of any of the REMICs provided for herein or
result in the imposition of tax upon any such REMIC; (h) not knowingly or
intentionally take any action or omit to take any action that would cause the
termination of the grantor trust status under Subpart E, Part I of Subchapter J
of the Code of any of the grantor trusts provided for herein or result in the
imposition of tax upon any such grantor trust; (i) pay, from the sources
specified in the last paragraph of this Section 8.12(a), the amount of any
federal, state and local taxes, including prohibited transaction taxes as
described below, imposed on each of the REMICs provided for herein prior to the
termination of the Trust Fund when and as the same shall be due and payable (but
such obligation shall not prevent the Trustee or any other appropriate Person
from contesting any such tax in appropriate proceedings and shall not prevent
the Trustee from withholding payment of such tax, if permitted by law, pending
the outcome of such proceedings); (j) sign or cause to be signed federal, state
or local income tax or information returns; (k) maintain records relating to
each of the REMICs provided for herein, including but not limited to the income,

proceedings relating to an examination or audit by any governmental taxing
authority, request an administrative adjustment as to any taxable year of any of
the REMICs provided for herein, enter into settlement agreements with any
governmental taxing agency, extend any statute of limitations relating to any
tax item of any of the REMICs provided for herein, and otherwise act on behalf
of each of the REMICs provided for herein in relation to any tax matter
involving any of such REMICs or any controversy involving the Trust Fund.

                                     -140-

<PAGE>

     In order to enable the Trustee to perform its duties as set forth herein,
the Depositor shall provide, or cause to be provided, to the Trustee within 10
days after the Closing Date all information or data that the Trustee requests in
writing and determines to be relevant for tax purposes to the valuations and
offering prices of the Certificates, including, without limitation, the price,
yield, prepayment assumption and projected cash flows of the Certificates and
the Mortgage Loans. Thereafter, the Depositor shall provide to the Trustee
promptly upon written request therefor, any such additional information or data
that the Trustee may, from time to time, request in order to enable the Trustee
to perform its duties as set forth herein. The Depositor hereby agrees to
indemnify the Trustee for any losses, liabilities, damages, claims or expenses
of the Trustee arising from any errors or miscalculations of the Trustee that
result from any failure of the Depositor to provide, or to cause to be provided,
accurate information or data to the Trustee on a timely basis.

     In the event that any tax is imposed on "prohibited transactions" of any of
the REMICs provided for herein as defined in Section 860F(a)(2) of the Code, on
the "net income from foreclosure property" of any of such REMICs as defined in
Section 860G(c) of the Code, on any contribution to the Trust Fund after the
Startup Day pursuant to Section 860G(d) of the Code, or any other tax is
imposed, if not paid as otherwise provided for herein, such tax shall be paid by
(i) the Trustee, if any such other tax arises out of or results from a breach by
the Trustee of any of its obligations under this Agreement or as a result of the
location of the Trustee, (ii) any party hereto (other than the Trustee) to the
extent any such other tax arises out of or results from a breach by such other
party of any of its obligations under this Agreement or as a result of the
location of such other party or (iii) in all other cases, or in the event that
any liable party here fails to honor its obligations under the preceding clauses
(i) or (ii), any such tax will be paid first with amounts (other than amounts
derived by the Issuing Entity from a payment on the Cap Contracts or amounts
received by the Supplemental Interest Trust as payments on the Swap Agreement)
otherwise to be distributed to the Class R Certificateholders (pro rata)
pursuant to Section 4.04, and second with amounts (other than amounts derived by
the Issuing Entity from a payment on the Cap Contracts or amounts received by
the Supplemental Interest Trust as payments on the Swap Agreement) otherwise to
be distributed to all other Certificateholders in the following order of
priority: first, to the Class C Certificates (pro rata), second to the Class B-3
Certificates (pro rata), third to the Class B-2 Certificates (pro rata), fourth
to the Class B-1 Certificates (pro rata), fifth to the Class M-6 Certificates
(pro rata), sixth to the Class M-5 Certificates (pro rata), seventh to the Class
M-4 Certificates (pro rata), eighth to the Class M-3 Certificates (pro rata),
ninth to the Class M-2 Certificates (pro rata), tenth to the Class M-1
Certificates (pro rata) and eleventh to the Class A Certificates (pro rata).
Notwithstanding anything to the contrary contained herein, to the extent that
such tax is payable by the Class R Certificate, the Trustee is hereby authorized
pursuant to such instruction to retain on any Distribution Date, from the
Holders of the Class R Certificate (and, if necessary, from the Holders of all
other Certificates in the priority specified in the preceding sentence), funds
otherwise distributable to such Holders in an amount sufficient to pay such tax.
The Trustee agrees to promptly notify in writing the party liable for any such
tax of the amount thereof and the due date for the payment thereof.

          (b) Each of the Depositor, the Servicer and the Trustee agrees not to
knowingly or intentionally take any action or omit to take any action that would
cause the termination of the REMIC status of any of the REMICs provided for
herein or result in the imposition of a tax upon any of the REMICs provided for
herein.

                                   ARTICLE IX

                                   TERMINATION

     SECTION 9.01. Termination upon Liquidation or Repurchase of all Mortgage
Loans

                                     -141-

<PAGE>

          (a) Subject to Section 9.03, the obligations and responsibilities of
the Depositor, the Servicer and the Trustee created hereby with respect to the
Trust Fund shall terminate upon the earlier of (a) an Optional Termination and
(b) the later of (i) the maturity or other liquidation (or any Advance with
respect thereto) of the last Mortgage Loan remaining in the Trust Fund and the
disposition of all REO Property and (ii) the distribution to Certificateholders
of all amounts required to be distributed to them pursuant to this Agreement, as
applicable. In no event shall the trusts created hereby continue beyond the
earlier of (i) the expiration of 21 years from the death of the last survivor of
the descendants of Joseph P. Kennedy, the late Ambassador of the United States
to the Court of St. James's, living on the date hereof and (ii) the Latest
Possible Maturity Date.

          (b) On or before the Determination Date following the Initial Optional
Termination Date, the Trustee shall attempt to terminate the Trust Fund by
conducting an auction of all of the Mortgage Loans and REO Properties via a
solicitation of bids from at least three (3) bidders, each of which shall be a
nationally recognized participant in mortgage finance (the "Auction"). In
addition, the Trustee will also solicit a bid from each Holder of a Class C
Certificate. The Trustee will notify the MI Insurer as soon as practicable after
the Initial Optional Termination Date that such an auction shall occur. The
Depositor and the Trustee agree to work in good faith to develop bid procedures
in advance of the Initial Optional Termination Date to govern the operation of
the Auction. The Trustee shall be entitled to retain an investment banking firm
and/or other agents in connection with the Auction, the cost of which shall be
included in the Optional Termination Price (unless an Optional Termination does
not occur in which case such costs shall be an expense of the Trust Fund). The
Trustee shall accept the highest bid received at the Auction; provided that the
amount of such bid equals or exceeds the Optional Termination Price. The Trustee
shall determine the Optional Termination Price based upon information provided
by (a) the Servicer with respect to the amounts described in clauses (i) and
(ii) of the definition of "Optional Termination Price" and (b) the Depositor
with respect to the information described in clauses (iii) and (iv) of the
definition of "Optional Termination Price"; provided, however, that with respect
to the Swap Termination Payment portion of the amounts described in clause (iv)
of the definition of "Optional Termination Price", the Trustee shall notify the
Swap Counterparty at least three (3) Business Days prior to the date of the
Auction of its intention to conduct such Auction and shall request from the Swap
Counterparty a good faith written estimate of the Swap Termination Payment based
upon termination of the Swap Agreement on or subsequent to the date of the
Auction but not later than two (2) Business Days prior to the related
Distribution Date. The Trustee may conclusively rely upon the information
provided to it in accordance with the immediately preceding sentence and shall
not have any liability for the failure of any party to provide such information.
The Trustee shall notify the bidders of the estimated Swap Termination Payment
received by the Trustee from the Swap Counterparty and that the winning bidder
will be responsible for the final Swap Termination Payment which may be higher
than such estimated Swap Termination Payment. If the Auction results in a
winning bid, the Trustee shall immediately notify the Swap Counterparty and the
MI Insurer that an Optional Termination has occurred, the identity, location and
contact information with respect to the winning bidder  and that final
distributions on the Certificates will be made on the immediately following
Distribution Date. Upon such notice, the Swap Counterparty shall inform the
Trustee in writing of the final Swap Termination Payment amount owed to the Swap
Counterparty and the Trustee shall communicate the final Swap Termination
Payment amount to the winning bidder.

     If the Trust Fund is terminated, the following conditions shall be met to
insure continued coverage of the MI Mortgage Loans under the MI Policy: (1) All
MI Mortgage Loans are transferred at the same time to a single new insured; (2)
the MI Insurer is given notice of the transfer and advised of the identity,
location and contact information of the new insured using a form of notice
approved by the MI Insurer as soon as practicable after the new insured has been
identified; (3) the Servicer, or any successor Servicer meeting the requirements
of a successor servicer set forth in Section 7.02, continues to service the
Loans; (4) the Servicer, or any successor Servicer meeting the requirements of a
successor servicer set

                                     -142-

<PAGE>

forth in Section 7.02, assumes the insured's obligation under this Agreement to
pay the MI Insurer Fee to the MI Insurer; (5) the MI Insurer is permitted by
applicable law to insure the new insured; and (6) the new insured agrees in a
writing approved by the MI Insurer to assume the Depositor's obligations under
the MI Policy.

     If an Optional Termination does not occur as a result of the Auction's
failure to achieve the Optional Termination Price or otherwise, the NIMS
Insurer, if any, may, on any Distribution Date following such Auction, at its
option, terminate the Trust Fund by purchasing all of the Mortgage Loans and REO
Properties at a price equal to the Optional Termination Price. If an Optional
Termination does not occur as a result of the Auction's failure to achieve the
Optional Termination Price and the NIMS Insurer fails to exercise its option to
purchase all of the Mortgage Loans, the Servicer may, on any Distribution Date
following such Auction, at its option, terminate the Trust Fund by purchasing
all of the Mortgage Loans and REO Properties at a price equal to the Optional
Termination Price. Upon the exercise of such option by the NIMs Insurer or the
Servicer, as the case may be, the Trustee shall immediately notify the Swap
Counterparty that an Optional Termination has occurred and that final
distributions on the Certificates will be made on the immediately following
Distribution Date. Upon such notice, the Swap Counterparty shall inform the
Trustee of the final Swap Termination Payment amount owed to the Swap
Counterparty. In connection with any such optional termination, the Optional
Termination Price shall be delivered to the Trustee no later than two Business
Days immediately preceding the related Distribution Date. Notwithstanding
anything to the contrary herein, the Optional Termination Amount paid to the
Trustee by the winning bidder at the Auction or by the Servicer shall be
deposited by the Trustee directly into the Certificate Account immediately upon
receipt. Upon any termination as a result of an Auction, the Trustee shall, out
of the Optional Termination Amount deposited into the Certificate Account, (x)
reimburse the Trustee for its costs and expenses necessary to conduct the
Auction and any other unreimbursed amounts owing to it and (y) pay to the
Servicer, the aggregate amount of any unreimbursed out-of-pocket costs and
expenses owed to the Servicer and any unpaid or unreimbursed Servicing Fees,
Advances and Servicing Advances. Notwithstanding anything herein to the
contrary, only an amount equal to the Optional Termination Price, reduced by the
portion thereof consisting of the sum of (x) any Swap Termination Payments and
(y) the amount of any unpaid Net Swap Payments that would not otherwise be
funded by the Optional Termination Price but for clause (iv) of the definition
of "Optional Termination Price" (such portion, the "Swap Optional Termination
Payment"), shall be made available for distribution to the Certificates. The
Swap Optional Termination Payment shall be withdrawn by the Trustee from the
Certificate Account and remitted to the Supplemental Interest Trust for payment
to the Swap Counterparty, it being understood that the Swap Termination Payment
portion of such Swap Optional Termination Payment shall be an amount equal to
the actual Swap Termination Payment amount determined by the Swap Counterparty
upon its receipt of notice from the Trustee of the Optional Termination of the
Trust as described above in this Section 9.01(b). The Swap Optional Termination
Payment shall not be part of any REMIC and shall not be paid into any account
which is part of any REMIC.

          (c) Notwithstanding anything to the contrary in clause (b) above, in
the event that the Trustee receives the written opinion of a nationally
recognized participant in mortgage finance acceptable to the Sponsor that the
Mortgage Loans and REO Properties to be included in the Auction will not be
saleable at a price sufficient to achieve the Optional Termination Price, the
Trustee need not conduct the Auction. In such event, the Servicer shall have the
option to purchase the Mortgage Loans and REO Properties at the Optional
Termination Price as of the Initial Optional Termination Date; provided that the
Swap Optional Termination Payment portion of the Optional Termination Price
received pursuant to this clause (c) shall be paid in full in a manner
consistent with the requirements of clause (b) above.

     SECTION 9.02. Final Distribution on the Certificates

                                     -143-

<PAGE>

     If on any Determination Date, (i) the Trustee determines that there are no
Outstanding Mortgage Loans and no other funds or assets in the Trust Fund other
than the funds in the Collection Account, the Trustee shall send a final
distribution notice promptly to each Certificateholder and the NIMs Insurer or
(ii) the Trustee determines that a Class of Certificates shall be retired after
a final distribution on such Class, the Trustee shall notify the
Certificateholders as soon as practicable after such Determination Date that the
final distribution in retirement of such Class of Certificates is scheduled to
be made on the immediately following Distribution Date. Any final distribution
made pursuant to the immediately preceding sentence will be made only upon
presentation and surrender of the Certificates at the office of the Trustee
specified in such notice.

     Notice of any termination of the Trust Fund, specifying the Distribution
Date on which Certificateholders may surrender their Certificates for payment of
the final distribution and cancellation, shall be given promptly by the Trustee
by letter to Certificateholders mailed as soon as practicable after a
determination is made pursuant to the preceding paragraph (or with respect to an
Auction, mailed no later than one Business Day following completion of such
Auction). Any such notice shall specify (a) the Distribution Date upon which
final distribution on the Certificates will be made upon presentation and
surrender of Certificates at the office therein designated, (b) the location of
the office or agency at which such presentation and surrender must be made, and
(c) that the Record Date otherwise applicable to such Distribution Date is not
applicable, distributions being made only upon presentation and surrender of the
Certificates at the office therein specified. The Trustee will give such notice
the NIMs Insurer, the Swap Counterparty, Cap Contract Counterparty and to each
Rating Agency at the time such notice is given to Certificateholders.

     In the event such notice is given, the Servicer shall remit all funds in
the Collection Account to the Trustee for deposit in the Certificate Account on
the Servicer Remittance Date in an amount equal to the final distribution in
respect of the Certificates. Upon such final deposit and the receipt by the
Trustee or the custodian of a Request for Release therefor, the Trustee or the
custodian shall promptly release to the Mortgage Files for the Mortgage Loans.

     Upon presentation and surrender of the Certificates, the Trustee shall
cause to be distributed to Certificateholders of each Class the amounts
allocable to such Certificates held in the Certificate Account in the order and
priority set forth in Section 4.04 hereof on the final Distribution Date and in
proportion to their respective Percentage Interests.

     In the event that any affected Certificateholders shall not surrender
Certificates for cancellation within six months after the date specified in the
above mentioned written notice, the Trustee shall give a second written notice
to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
six months after the second notice all the applicable Certificates shall not
have been surrendered for cancellation, the Trustee may take appropriate steps,
or may appoint an agent to take appropriate steps, to contact the remaining
Certificateholders concerning surrender of their Certificates, and the cost
thereof shall be paid out of the funds and other assets that remain a part of
the Trust Fund. If within one year after the second notice all Certificates
shall not have been surrendered for cancellation, the Class R Certificateholders
shall be entitled to all unclaimed funds and other assets of the Trust Fund that
remain subject hereto. Upon payment to the Class R Certificateholders of such
funds and assets, the Trustee shall not have any further duties or obligations
with respect thereto.

     SECTION 9.03. Additional Termination Requirements

                                     -144-

<PAGE>

          (a) In the event the Trustee or the Servicer completes an Optional
Termination as provided in Section 9.01, the Trust Fund shall be terminated in
accordance with the following additional requirements, unless the Trustee has
been supplied with an Opinion of Counsel, at the expense of the NIMs Insurer or
Servicer, as applicable, to the effect that the failure of the Issuing Entity to
comply with the requirements of this Section 9.03 will not (i) result in the
imposition of taxes on "prohibited transactions" of any of the REMICs provided
for herein as defined in Section 860F of the Code, or (ii) cause any of the
REMICs provided for herein to fail to qualify as a REMIC at any time that any
Certificates are outstanding:

          (i) The Depositor shall establish a 90-day liquidation period and
     notify the Trustee thereof, and the Trustee shall in turn specify the first
     day of such period in a statement attached to the final tax returns of each
     of the REMICs provided for herein pursuant to Treasury Regulation Section
     1.860F-1. The Depositor shall satisfy all the requirements of a qualified
     liquidation under Section 860F of the Code and any regulations thereunder,
     as evidenced by an Opinion of Counsel obtained at the expense of the
     Servicer;

          (ii) During such 90-day liquidation period, and at or prior to the
     time of making the final payment on the Certificates, the Depositor as
     agent of the Trustee shall sell all of the assets of the Trust Fund for
     cash; and

          (iii) At the time of the making of the final payment on the
     Certificates, the Trustee shall distribute or credit, or cause to be
     distributed or credited, to the Class R Certificateholders all cash on hand
     (other than cash retained to meet outstanding claims), and the Trust Fund
     shall terminate at that time, whereupon the Trustee shall have no further
     duties or obligations with respect to sums distributed or credited to the
     Class R Certificateholders.

          (b) By their acceptance of the Certificates, the Holders thereof
hereby authorize the Depositor to specify the 90-day liquidation period for the
Trust Fund, which authorization shall be binding upon all successor
Certificateholders.

          (c) The Trustee as agent for each REMIC hereby agrees to adopt and
sign such a plan of complete liquidation prepared and delivered to it by
Depositor upon the written request of the Depositor, and the receipt of the
Opinion of Counsel referred to in Section 9.03(a) and to take such other action
in connection therewith as may be reasonably requested by the Depositor.

          (d) Notwithstanding any other terms of this Agreement, prior to any
termination of the Trust Fund, the Servicer may prepare a reconciliation of all
Advances and Servicing Advances made by it for which it has not been reimbursed
and a reasonable estimate of all additional Servicing Advances and other costs
for which it would be entitled to be reimbursed if the Trust Fund were not being
terminated, including without limitation, any Servicing Advances and other costs
arising under Section 6.03 (Limitation on Liability of the Depositor, the
Servicer and Others), and the Servicer may recover these Advances, Servicing
Advances and estimated Servicing Advances and other costs from the Collection
Account (to the extent that such recovery of Servicing Advances, estimated
Servicing Advances and other costs constitutes "unanticipated expenses" within
the meaning of Treasury Regulation Section 1.860G-1(b)(3)(ii)).

          (e) Notwithstanding any other terms of this Agreement, unless the
Servicer previously has notified the Trustee that it has entered into a
servicing agreement for the servicing after the termination date of the Trust
Fund assets, at least 20 days prior to any termination of the Trust Fund, the
Trustee or the Depositor shall notify the Servicer in writing to transfer the
assets of the Trust Fund as of the termination date to the person specified in
the notice, or if such person is not then known, to continue

                                      -145-

servicing the assets until the date that is 20 days after the termination date
and on the termination date, the Trustee or the Depositor shall notify the
Servicer of the person to whom the assets should be transferred on that date. In
the latter event the Servicer shall be entitled to recover its servicing fee and
any advances made for the interim servicing period from the collections on the
assets which have been purchased from the Trust and the new owner of the assets,
and the agreements for the new owner to obtain ownership of the assets of the
Trust Fund shall so provide.

                            MISCELLANEOUS PROVISIONS

     SECTION 10.01. Amendment

     This Agreement may be amended from time to time by the Depositor, the
Servicer and the Trustee, with the consent of the NIMs Insurer and without the
consent of any of the Certificateholders,

          (i) to cure any ambiguity or correct any mistake,

          (ii) to correct, modify or supplement any provision herein which may
     be inconsistent with the Prospectus Supplement or any other provision
     herein,

          (iii) to add any other provisions with respect to matters or questions
     arising under this Agreement, or

          (iv) to modify, alter, amend, add to or rescind any of the terms or
     provisions contained in this Agreement, provided, however, that, in the
     case of clauses (iii) and (iv), such amendment will not, as evidenced by an
     Opinion of Counsel addressed to the Trustee to such effect, adversely
     affect in any material respect the interests of any Holder; provided,
     further, however, that such amendment will be deemed to not adversely
     affect in any material respect the interest of any Holder if the Person
     requesting such amendment obtains a letter from each Rating Agency stating
     that such amendment will not result in a reduction or withdrawal of its
     rating of any Class of the Certificates, it being understood and agreed
     that any such letter in and of itself will not represent a determination as
     to the materiality of any such amendment and will represent a determination
     only as to the credit issues affecting any such rating. In addition, this
     Agreement may be amended from time to time by the Depositor, the Servicer
     and the Trustee without the consent of any of the Certificateholders and
     without a determination as set forth in subsection (ii)(A) of the fourth
     from last paragraph of this Section 10.01 to comply with the provisions of
     Regulation AB.

     Notwithstanding the foregoing, without the consent of the
Certificateholders, the Depositor, the Servicer and the Trustee may at any time
and from time to time amend this Agreement to modify, eliminate or add to any of
its provisions to such extent as shall be necessary or appropriate to maintain
the qualification of any of the REMICs provided for herein as REMICs under the
Code or to avoid or minimize the risk of the imposition of any tax on the Trust
Fund or any of the REMICs provided for herein pursuant to the Code that would be
a claim against the Trust Fund at any time prior to the final redemption of the
Certificates, provided that the Trustee and the NIMs Insurer shall have been
provided an Opinion of Counsel, which opinion shall be an expense of the party
requesting such amendment but in any case shall not be an expense of the Trustee
or the NIMs Insurer, to the effect that such action is necessary or appropriate
to maintain such qualification or to avoid or minimize the risk of the
imposition of such a tax.

                                      -146-

<PAGE>

     This Agreement may also be amended from time to time by the Depositor, the
Trustee, the Servicer, the Trustee and the Holders of the Certificates affected
thereby evidencing not less than 66 2/3% of the Voting Rights, with the consent
of the NIMs Insurer, for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Agreement or of
modifying in any manner the rights of the Holders of Certificates; provided,
however, that no such amendment shall (i) reduce in any manner the amount of, or
delay the timing of, payments required to be distributed on any Certificate
without the consent of the Holder of such Certificate, (ii) adversely affect in
any material respect the interests of the Holders of any Class of Certificates
in a manner other than as described in (i), without the consent of the Holders
of Certificates of such Class evidencing 66 2/3% or more of the Voting Rights of
such Class or (iii) reduce the aforesaid percentages of Certificates the Holders
of which are required to consent to any such amendment without the consent of
the Holders of all such Certificates then outstanding. A copy of such Opinion of
Counsel shall be provided to the NIMs Insurer.

     Notwithstanding any contrary provision of this Agreement, the Trustee shall
not consent to any amendment to this Agreement unless it shall have first
received an Opinion of Counsel, which opinion shall be an expense of the party
requesting such amendment but in any case shall not be an expense of the
Trustee, to the effect that such amendment will not cause the imposition of any
tax on the Trust Fund, any of the REMICs provided for herein or the
Certificateholders or cause any of the REMICs provided for herein to fail to
qualify as a REMIC at any time that any Certificates are outstanding.

     Promptly after the execution of any amendment to this Agreement requiring
the consent of Certificateholders, the Trustee shall furnish written
notification of the substance of such amendment to each Certificateholder, the
Swap Counterparty and each Rating Agency.

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

     Nothing in this Agreement shall require the Trustee or the Servicer to
enter into an amendment without receiving an Opinion of Counsel, satisfactory to
the Trustee or the Servicer that (i) such amendment is permitted and is not
prohibited by this Agreement and that all requirements for amending this
Agreement have been complied with; and (ii) either (A) the amendment does not
adversely affect in any material respect the interests of any Certificateholder
or (B) the conclusion set forth in the immediately preceding clause (A) is not
required to be reached pursuant to this Section 10.01.

     The Trustee may, but shall not be obligated to, enter into any supplement,
modification or waiver which affects its rights, duties or obligations
hereunder.

     The Trustee shall not enter into any amendment to this Agreement that could
have a materially adverse effect on the Swap Counterparty or the Cap Contract
Counterparty without first obtaining the consent of the Swap Counterparty or the
Cap Contract Counterparty, as applicable.

     Notwithstanding anything to the contrary in this Section 10.01, the Trustee
and the Servicer shall reasonably cooperate with the Depositor and its counsel
to enter into such amendments or modifications to this Agreement as may be
necessary to comply with Regulation AB and any interpretation thereof by the
Commission.

     SECTION 10.02. Counterparts

                                     -147-

     This Agreement may be executed simultaneously in any number of
counterparts, each of which counterparts shall be deemed to be an original, and
such counterparts shall constitute but one and the same instrument.

     SECTION 10.03. Governing Law

     THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE
SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO
BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND REMEDIES
OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN
ACCORDANCE WITH SUCH LAWS WITHOUT REGARD TO THE CONFLICTS OF LAWS PRINCIPLES
THEREOF.

     SECTION 10.04. Intention of Parties

     It is the express intent of the parties hereto that the conveyance of the
Mortgage Notes, Mortgages, assignments of Mortgages, title insurance policies
and any modifications, extensions and/or assumption agreements and private
mortgage insurance policies relating to the Mortgage Loans by the Depositor to
the Trustee be, and be construed as, an absolute sale thereof to the Trustee. It
is, further, not the intention of the parties that such conveyance be deemed a
pledge thereof by the Depositor to the Trustee. However, in the event that,
notwithstanding the intent of the parties, such assets are held to be the
property of the Depositor, or if for any other reason this Agreement is held or
deemed to create a security interest in such assets, then (i) this Agreement
shall be deemed to be a security agreement within the meaning of the Uniform
Commercial Code of the State of New York and (ii) the conveyance provided for in
this Agreement shall be deemed to be an assignment and a grant by the Depositor
to the Trustee, for the benefit of the Certificateholders, of a security
interest in all of the assets that constitute the Trust Fund, whether now owned
or hereafter acquired.

     The Depositor for the benefit of the Certificateholders shall, to the
extent consistent with this Agreement, take such actions as may be necessary to
ensure that, if this Agreement were deemed to create a security interest in the
assets of the Trust Fund, such security interest would be deemed to be a
perfected security interest of first priority under applicable law and will be
maintained as such throughout the term of the Agreement. The Depositor shall
arrange for filing any Uniform Commercial Code continuation statements in
connection with any security interest granted or assigned to the Trustee for the
benefit of the Certificateholders.

     SECTION 10.05. Notices

          (a) The Trustee shall use its best efforts to promptly provide notice
to the NIMs Insurer, the Swap Counterparty and each Rating Agency with respect
to each of the following of which it has actual knowledge:

          (i) Any material change or amendment to this Agreement;

          (ii) The occurrence of any Event of Default that has not been cured;

          (iii) The resignation or termination of the Trustee or the Servicer
     and the appointment of any successor;

          (iv) The repurchase or substitution of Mortgage Loans pursuant to
     Sections 2.02, 2.03 and 3.12;

                                     -148-

          (v) The final payment to Certificateholders; and

          (vi) Any change in the location of the Certificate Account.

Rating Agency copies of the following:

          (i) Each report to Certificateholders described in Section 4.05;

          (ii) Each annual statement as to compliance described in Section 3.17;
     and

prepaid, to their respective addresses appearing in the Certificate Register.

     SECTION 10.06. Severability of Provisions

     If any one or more of the covenants, agreements, provisions or terms of
this Agreement shall be for any reason whatsoever held invalid, then such
covenants, agreements, provisions or terms shall be deemed severable from the
remaining covenants, agreements, provisions or terms of this Agreement and shall
in no way affect the validity or enforceability of the other provisions of this
Agreement or of the Certificates or the rights of the Holders thereof.

     SECTION 10.07. Assignment

     Notwithstanding anything to the contrary contained herein, except as
provided pursuant to Section 6.02, this Agreement may not be assigned by the
Servicer without the prior written consent of the Trustee and Depositor;
provided, however, the Servicer is hereby authorized to enter into an Advance
Facility under which (l) the Servicer sells, assigns or pledges to an Advancing
Person the Servicer's rights under this Agreement to be reimbursed for any
Advances or Servicing Advances and/or (2) an Advancing Person agrees to fund
some or all Advances or Servicing Advances required to be made by the Servicer
pursuant to this Agreement. No consent of the Trustee, Certificateholders or any
other party is required before the Servicer may enter into an Advance Facility.
Notwithstanding the existence of any Advance Facility under which an Advancing
Person agrees to fund Advances and/or Servicing Advances on the

                                     -149-

<PAGE>

Servicer's behalf, the Servicer shall remain obligated pursuant to this
Agreement to make Advances and Servicing Advances pursuant to and as required by
this Agreement, and shall not be relieved of such obligations by virtue of such
Advance Facility.

     Reimbursement amounts shall consist solely of amounts in respect of
Advances and/or Servicing Advances made with respect to the Mortgage Loans for
which the Servicer would be permitted to reimburse itself in accordance with
this Agreement, assuming the Servicer had made the related Advance(s) and/or
Servicing Advance(s).

     The Servicer shall maintain and provide to any successor Servicer a
detailed accounting on a loan by loan basis as to amounts advanced by, pledged
or assigned to, and reimbursed to any Advancing Person. The successor Servicer
shall be entitled to rely on any such information provided by the predecessor
Servicer, and the successor Servicer shall not be liable for any errors in such
information.

     An Advancing Person who purchases or receives an assignment or pledge of
the rights to be reimbursed for Advances and/or Servicing Advances, and/or whose
obligations hereunder are limited to the funding of Advances and/or Servicing
Advances shall not be required to meet the criteria for qualification of a
Subservicer set forth in this Agreement.

     The documentation establishing any Advance Facility shall require that such
reimbursement amounts distributed with respect to each Mortgage Loan be
allocated to outstanding unreimbursed Advances or Servicing Advances (as the
case may be) made with respect to that Mortgage Loan on a "first in, first out"
(FIFO) basis. Such documentation shall also require the Servicer to provide to
the related Advancing Person or its designee loan by loan information with
respect to each such reimbursement amount distributed to such Advancing Person
or Advance Facility trustee on each Distribution Date, to enable the Advancing
Person or Advance Facility trustee to make the FIFO allocation of each such
reimbursement amount with respect to each Mortgage Loan. The Servicer shall
remain entitled to be reimbursed by the Advancing Person or Advance Facility
trustee for all Advances and Servicing Advances funded by the Servicer to the
extent the related rights to be reimbursed therefor have not been sold, assigned
or pledged to an Advancing Person.

     Any amendment to this Section 10.07 or to any other provision of this
Agreement that may be necessary or appropriate to effect the terms of an Advance
Facility as described generally in this Section 10.07, including amendments to
add provisions relating to a successor Servicer, may be entered into by the
Trustee and the Servicer, without the consent of any Certificateholder
notwithstanding anything to the contrary in this Agreement, upon receipt by the
Trustee of an Opinion of Counsel that such amendment has no material adverse
effect on the Certificateholders or written confirmation from the Rating
Agencies that such amendment will not adversely affect the ratings on the
Certificates. Prior to entering into an Advance Facility, the Servicer shall
notify the lender under such facility in writing that: (a) the Advances financed
by and/or pledged to the lender are obligations owed to the Servicer on a non
recourse basis payable only from the cash flows and proceeds received under this
Agreement for reimbursement of Advances only to the extent provided herein, and
the Trustee and the Trust Fund are not otherwise obligated or liable to repay
any Advances financed by the lender; (b) the Servicer will be responsible for
remitting to the lender the applicable amounts collected by it as reimbursement
for Advances funded by the lender, subject to the restrictions and priorities
created in this Agreement; and (c) the Trustee shall not have any responsibility
to track or monitor the administration of the financing arrangement between the
Servicer and the lender.

     SECTION 10.08. Limitation on Rights of Certificateholders

                                     -150-

<PAGE>

     The death or incapacity of any Certificateholder shall not operate to
terminate this Agreement or the Trust Fund, nor entitle such Certificateholder's
legal representative or heirs to claim an accounting or to take any action or
commence any proceeding in any court for a petition or winding up of the Trust
Fund, or otherwise affect the rights, obligations and liabilities of the parties
hereto or any of them.

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

     No Certificateholder shall have any right by virtue or by availing itself
of any provisions of this Agreement to institute any suit, action or proceeding
in equity or at law upon or under or with respect to this Agreement, unless such
Holder previously shall have given to the Trustee a written notice of an Event
of Default and of the continuance thereof, as hereinbefore provided, the Holders
of Certificates evidencing not less than 25% of the Voting Rights evidenced by
the Certificates shall also have made written request to the Trustee to
institute such action, suit or proceeding in its own name as Trustee hereunder
and shall have offered to the Trustee (individually and as trustee) such
indemnity satisfactory to it as it may require against the costs, expenses, and
liabilities to be incurred therein or thereby, and the Trustee, for 60 days
after its receipt of such notice, request and offer of indemnity shall have
neglected or refused to institute any such action, suit or proceeding; it being
understood and intended, and being expressly covenanted by each
Certificateholder with every other Certificateholder and the Trustee, that no
one or more Holders of Certificates shall have any right in any manner whatever
by virtue or by availing itself or themselves of any provisions of this
Agreement to affect, disturb or prejudice the rights of the Holders of any other
of the Certificates and/or the NIMs Insurer, or to obtain or seek to obtain
priority over or preference to any other such Holder and/or the NIMs Insurer or
to enforce any right under this Agreement, except in the manner herein provided
and for the common benefit of all Certificateholders. For the protection and
enforcement of the provisions of this Section 10.08, each and every
Certificateholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

     SECTION 10.09. Inspection and Audit Rights

     The Servicer agrees that, on reasonable prior notice, it will permit any
representative of the Depositor or the Trustee during the Servicer's normal
business hours, to examine all the books of account, records, reports and other
papers of the Servicer relating to the Mortgage Loans to make copies and
extracts therefrom, to cause such books to be audited by independent certified
public accountants selected by the Depositor or the Trustee and to discuss its
affairs, finances and accounts relating to the Mortgage Loans with its officers,
employees, agents, counsel and independent public accountants (and by this
provision the Servicer hereby authorizes such accountants to discuss with such
representative such affairs, finances and accounts), all at such reasonable
times and as often as may be reasonably requested. Any out-of-pocket expense
incident to the exercise by the Depositor or the Trustee of any right under this
Section 10.09 shall be borne by the party requesting such inspection (except in
the case of the Trustee in which case such expenses shall be borne by the
requesting Certificateholder(s)); all other such expenses shall be borne by the
Servicer.

     SECTION 10.10. Certificates Nonassessable and Fully Paid

     It is the intention of the Depositor that Certificateholders shall not be
personally liable for obligations of the Issuing Entity, that the interests in
the Issuing Entity represented by the Certificates

                                     -151-

<PAGE>

shall be nonassessable for any reason whatsoever, and that the Certificates,
upon due authentication thereof by the Authenticating Agent pursuant to this
Agreement, are and shall be deemed fully paid.

     SECTION 10.11. Compliance with Regulation AB

     Each of the parties hereto acknowledges and agrees that the purpose of
Sections 3.17, 3.18 and 3.20 of this Agreement 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 (a) the
obligations of the parties hereunder shall be interpreted in such a manner as to
accomplish compliance with Regulation AB, (b) the parties' obligations hereunder
will be supplemented and modified as necessary to be consistent with any such
amendments, interpretive advice or guidance, or convention or consensus among
active participants in the asset-backed securities markets in respect of the
requirements of Regulation AB and (c) the parties shall comply with reasonable
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, provided that such information is
available to such party without unreasonable effort or expense and within such
timeframe as may be reasonably requested.

     SECTION 10.12. Third Party Rights

     Each of the NIMs Insurer, the MI Insurer and the Swap Counterparty shall be
deemed a third-party beneficiary of this Agreement to the same extent as if it
were a party hereto, and shall have the right to enforce the provisions of this
Agreement.

     The Cap Contract Counterparty shall be deemed a third party beneficiary of
this Agreement regarding provisions related to payments owed to the Cap Contract
Counterparty or to the Supplemental Interest Trust on behalf of the Cap Contract
Counterparty.

     SECTION 10.13. Additional Rights of the NIMs Insurer

     Each party to this Agreement, any agent thereof and any successor thereto
shall furnish to the NIMs Insurer a copy of any notice, direction, demand,
opinion, schedule, list, certificate, report, statement, filing, information,
data or other communication provided by it or on its behalf to any other Person
pursuant to this Agreement at the same time, in the same form and in the same
manner as such communication is so provided and shall address or cause such
communication to be addressed to the NIMs Insurer in addition to any other
addressee thereof. The Servicer shall cause the NIMs Insurer to be an addressee
of any report furnished pursuant to this Agreement. With respect to the Trustee,
such obligation shall be satisfied with the provision of access to the NIMs
Insurer to the Trustee's website.

     Wherever in this Agreement there shall be a requirement that there be no
downgrade, reduction, withdrawal or qualification of or other effect on the
rating of any Class of Certificates by any Rating Agency as of any date, there
also shall be deemed to be a requirement that there be no such effect on any
class of notes issued pursuant to the Indenture and guaranteed by the NIMs
Insurer as of such date. In addition, unless there exists a continuance of any
failure by the NIMs Insurer to make a required payment under the policy insuring
the NIM Notes (such event, a "NIMs Insurer Default"), wherever in this Agreement
there shall be a requirement that any Person or any communication, object or
other matter be acceptable or satisfactory to or otherwise receive the consent
or other approval of any other Person (whether as a condition to the eligibility
of such Person to act in any capacity, as a condition to any circumstance or
state of affairs related to such matter, or otherwise), there also shall be
deemed to be a requirement that such Person or matter be approved in writing by
the NIMs Insurer, which approval shall not be unreasonably withheld or delayed.

     SECTION 10.14. Trustee to Retain Possession of Certain Insurance Policies
and Documents

     The Trustee shall retain possession and custody of the originals (to the
extent available) of any primary mortgage insurance policies (including, without
limitation, the MI Policy), 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 Trustee and the Servicer
have otherwise fulfilled their respective obligations under this Agreement, the
Trustee shall also retain possession and custody of each Mortgage File in
accordance with and subject to the terms and conditions of this Agreement. For
the avoidance of doubt, the Trustee shall have no obligations, duties or
liabilities with respect to such insurance policies (including, without
limitation, the MI Policy), including the duty to make premium payments or
otherwise monitor such insurance policies.

                           Series 2006-HE6

evidencing an ownership interest in distributions allocable to the Class
A-[_____] Certificates with respect to a pool of conventional, sub-prime
mortgage loans formed and sold by

                MERRILL LYNCH MORTGAGE INVESTORS, INC.

     Unless this Certificate is presented by an authorized representative of The
Depository Trust Company, a New York corporation ("DTC"), to the Trustee for
registration of transfer, exchange or payment, and any certificate issued is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC (and any payment is made to Cede & Co. or to
such other entity as is requested by an authorized representative of DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co. has an interest
herein.

     This certifies that CEDE & CO. is the registered owner of the ownership
interest (the "Ownership Interest") evidenced by this Certificate (obtained by
dividing the Original Denomination of this Certificate by the aggregate Initial
Certificate Balance of all Class A-[_____] Certificates) in certain
distributions with respect to a pool of conventional, sub-prime mortgage loans
(the "Mortgage Loans") formed and sold by Merrill Lynch Mortgage Investors, Inc.
(hereinafter called the "Depositor"), and certain other property held in trust
for the benefit of Certificateholders (collectively, the "Trust Fund"). The
Mortgage Loans are serviced by Wilshire Credit Corporation (the "Servicer") and
are secured by first-lien or second-lien mortgages on the Mortgaged Properties.
The Trust Fund was created pursuant to a pooling and servicing agreement (the
"Agreement"), dated as of December 1, 2006, among the Depositor, the Servicer
and LaSalle Bank National Association, as trustee (the "Trustee"), a summary of
certain of the pertinent provisions of which is set forth hereafter. To the
extent not defined herein, the capitalized terms used herein have the meanings
assigned in the Agreement.

     This Certificate is one of a duly authorized issue of Certificates,
designated as Merrill Lynch Mortgage Investors Trust Mortgage Loan Asset-Backed
Certificates, Series 2006-HE6, Class A-[_____] (the "Class A-[_____]
Certificates") and is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which Agreement such Holder is
bound.

     The Class A Certificates, the Class M Certificates, the Class B
Certificates, the Class P Certificates and the Class C Certificates are
collectively referred to herein as the "Certificates."

     Pursuant to the terms of the Agreement, the Trustee will distribute from
funds in the Certificate Account the amounts described in the Agreement on the
25th day of each month or, if such 25th day is not a Business Day, the Business
Day immediately following (the "Distribution Date"), commencing in January 2007.
Such distributions will be made to the Person in whose

                                 A-3

<PAGE>

name this Certificate is registered at the close of business on the last
Business Day of the month preceding the month in which such payment is made.

     Distributions on this Certificate will be made either by check mailed to
the address of the person entitled to distributions as it appears on the
Certificate Register or, in the case of any certificateholder that has so
notified the Trustee in writing in accordance with the Agreement, by wire
transfer in immediately available funds to the account of such certificateholder
at a bank or other depository institution having appropriate wire transfer
facilities; provided, however, that the final distribution in retirement of the
certificates will be made only upon presentation and surrender of this
Certificate at the office of the Trustee or such other address designated in
writing by the Trustee. On each Distribution Date, a Holder of this Certificate
will receive such holder's Percentage Interest of the amounts required to be
distributed with respect to the applicable Class of Certificates.

     The Trustee will maintain or cause to be maintained a Certificate Register
in which, subject to such reasonable regulations as it may prescribe, the
Trustee will provide for the registration of Certificates and of transfers and
exchanges of Certificates. Upon surrender for registration of transfer of any
Certificate at any office or agency of the Trustee, or, if an Authenticating
Agent has been appointed under the Agreement, the Authenticating Agent,
maintained for such purpose, the Trustee, will, subject to the limitations set
forth in the Agreement, authenticate and deliver, in the name of the designated
transferee or transferees, a Certificate of a like class and dated the date of
authentication by the Authenticating Agent. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the Trustee,
of the pendency of such distribution and only upon presentation and surrender of
this Certificate at the office or agency appointed by the Trustee, for that
purpose and specified in such notice of final distribution.

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

     Unless the certificate of authentication has been executed by the
Authenticating Agent, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

                                 A-4

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

                    MORTGAGE LOAN ASSET-BACKED CERTIFICATES,
                                 Series 2006-HE6

     This Certificate is one of a duly authorized issue of Certificates,
designated as Merrill Lynch Mortgage Investors Trust Mortgage Loan Asset-Backed
Certificates, Series 2006-HE6, issued in one or more Classes of Class A
Certificates, Class M Certificates, Class B Certificates, Class P Certificates
and Class C Certificates, each evidencing an interest in certain distributions
with respect to a pool of conventional, sub-prime Mortgage Loans formed and sold
by the Depositor and certain other property conveyed by the Depositor to the
Trustee.

     Following the initial issuance of the Certificates, the principal balance
of this Certificate will be different from the Original Denomination shown
above. Anyone acquiring this Certificate may ascertain its current principal
balance by inquiry of the Trustee.

     The Holder, by its acceptance of this Certificate, agrees that it will look
solely to the Trust Fund and certain amounts resulting from credit enhancements
for payment hereunder and that the Trustee is not liable to the Holders for any
amount payable under this Certificate or the Agreement or, except as expressly
provided in the Agreement, subject to any liability under the Agreement.

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

     No service charge will be made to the Holder for any transfer or exchange
of the Certificate, but the Trustee may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer or exchange of the Certificate. Prior to due presentation of a
Certificate for registration of transfer, the Depositor and the Trustee may
treat the person in whose name any Certificate is registered as the owner of
such Certificate and the Percentage Interest in the Trust Fund evidenced thereby
for the purpose of receiving distributions pursuant to the Agreement and for all
other purposes whatsoever, and neither the Depositor nor the Trustee will be
affected by notice to the contrary.

     The Agreement may be amended from time to time by the Depositor, the
Servicer and the Trustee, without the consent of any of the Certificateholders,
to cure any ambiguity, to correct or supplement any provisions therein which may
be inconsistent with the other provisions therein, to ensure continuing
treatment of each REMIC included in the Trust Fund as a REMIC, or to make any
other provisions with respect to matters or questions arising under the
Agreement which are not materially inconsistent with the provisions of the
Agreement, provided that such action does not, as evidenced by an Opinion of
Counsel, adversely affect in any material respect the interests of any
Certificateholder.

     The Agreement may also be amended from time to time by the Depositor, the
Servicer and the Trustee, with the consent of the Holders of Certificates
evidencing in the aggregate not

                                       A-6

<PAGE>

less than 66 2/3% of the Percentage Interests of each Class of Certificates
affected thereby, for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of the Agreement or of modifying in
any manner the rights of the Holders of Certificates of such Class; provided,
however, that no such amendment may (i) reduce in any manner the amount of, or
delay the timing of, payments received on Mortgage Loans which are required to
be distributed on any Certificate without the consent of the Holder of such
Certificate, (ii) adversely affect in any material respect the interests of the
Holders of any Class of Certificates in a manner other than as described in
clause (i), without the consent of the Holders of Certificates of such Class
evidencing 66 2/3% or more of the Voting Rights of such Class or (iii) change
the percentage specified in clause (ii) of the third paragraph of Section 10.01
of the Agreement, without the consent of the Holders of all Certificates of such
Class then outstanding.

     The Class A-[_____] Certificates are issuable only in registerable form, in
minimum denominations of $25,000 in initial Certificate Principal Amount and in
integral multiples of $1 in excess thereof, registered in the name of the
nominee of the Clearing Agency, which shall maintain such Certificates through
its book-entry facilities.

     For federal income tax purposes, the Trust Fund will include multiple "real
estate mortgage investment conduits" (each, a "REMIC") in a tiered REMIC
structure. The REMIC Regular Interests will represent "regular interests" in one
of the REMICs included in the Trust Fund. The Class R Certificate will represent
the sole class of "residual interest" in each of the REMICs.

     The obligations and responsibilities of the Depositor, the Servicer and the
Trustee under the Agreement shall terminate upon the earlier of (a) the exercise
by the Trustee of an Optional Termination; and (b) the later of (i) the maturity
or other liquidation (or any Advance with respect thereto) of the last Mortgage
Loan remaining in the Trust Fund and the disposition of all REO Property and
(ii) the distribution to Certificateholders of all amounts required to be
distributed to them pursuant to this Agreement, as applicable. In no event shall
the trusts created under the Agreement continue beyond the earlier of (i) the
expiration of 21 years from the death of the last survivor of the descendants of
Joseph P. Kennedy, the late Ambassador of the United States to the Court of St.
James's, living on the date hereof and (ii) the Latest Possible Maturity Date.

     Unless this Certificate is presented by an authorized representative of The

registration of transfer, exchange or payment, and any certificate issued is
registered in the name of Cede & Co. or in such other name as is requested by an

such other entity as is requested by an authorized representative of DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co. has an interest

     This certifies that CEDE & CO. is the registered owner of the ownership
interest (the "Ownership Interest") evidenced by this Certificate (obtained by
dividing the Original Denomination of this Certificate by the aggregate Initial
Certificate Balance of all Class M-[_____] Certificates) in certain
distributions with respect to a pool of conventional, sub-prime mortgage loans
(the "Mortgage Loans") formed and sold by Merrill Lynch Mortgage Investors, Inc.
(hereinafter called the "Depositor"), and certain other property held in trust
for the benefit of Certificateholders (collectively, the "Trust Fund"). The
Mortgage Loans are serviced by Wilshire Credit Corporation (the "Servicer") and
are secured by first-lien or second-lien mortgages on the Mortgaged Properties.
The Trust Fund was created pursuant to a pooling and servicing agreement (the
"Agreement"), dated as of December 1, 2006, among the Depositor, the Servicer
and LaSalle Bank National Association, as trustee (the "Trustee"), a summary of
certain of the pertinent provisions of which is set forth hereafter. To the

     This Certificate is one of a duly authorized issue of Certificates,

Certificates") and is issued under and is subject to the terms, provisions and

by virtue of the acceptance hereof assents and by which Agreement such Holder is
bound.

     The Class A Certificates, the Class M Certificates, the Class B

     Pursuant to the terms of the Agreement, the Trustee will distribute from
funds in the Certificate Account the amounts described in the Agreement on the
25th day of each month or, if such 25th day is not a Business Day, the Business
Day immediately following (the "Distribution Date"), commencing in January 2007.

Certificate Register or, in the case of any certificateholder that has so

at a bank or other depository institution having appropriate wire transfer
facilities; provided, however, that the final distribution in retirement of the

Certificate at the office of the Trustee or such other address designated in
writing by the Trustee. On each Distribution Date, a Holder of this Certificate
will receive such holder's Percentage Interest of the amounts required to be
distributed with respect to the applicable Class of Certificates.

     The Trustee will maintain or cause to be maintained a Certificate Register
in which, subject to such reasonable regulations as it may prescribe, the
Trustee will provide for the registration of Certificates and of transfers and
exchanges of Certificates. Upon surrender for registration of transfer of any
Certificate at any office or agency of the Trustee, or, if an Authenticating
Agent has been appointed under the Agreement, the Authenticating Agent,
maintained for such purpose, the Trustee, will, subject to the limitations set
forth in the Agreement, authenticate and deliver, in the name of the designated
transferee or transferees, a Certificate of a like class and dated the date of
authentication by the Authenticating Agent. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the Trustee,
of the pendency of such distribution and only upon presentation and surrender of

forth on the reverse hereof which further provisions shall for all purposes have
the same effect as if set forth at this place.

     Unless the certificate of authentication has been executed by the
Authenticating Agent, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

                             REVERSE OF CERTIFICATE

                     MERRILL LYNCH MORTGAGE INVESTORS TRUST
                    MORTGAGE LOAN ASSET-BACKED CERTIFICATES,
                                 Series 2006-HE6

     This Certificate is one of a duly authorized issue of Certificates,
designated as Merrill Lynch Mortgage Investors Trust Mortgage Loan Asset-Backed
Certificates, Series 2006-HE6, issued in one or more Classes of Class A
Certificates, Class M Certificates, Class B Certificates, Class P Certificates
and Class C Certificates, each evidencing an interest in certain distributions
with respect to a pool of conventional, sub-prime Mortgage Loans formed and sold
by the Depositor and certain other property conveyed by the Depositor to the
Trustee.

     Following the initial issuance of the Certificates, the principal balance
of this Certificate will be different from the Original Denomination shown
above. Anyone acquiring this Certificate may ascertain its current principal
balance by inquiry of the Trustee.

     The Holder, by its acceptance of this Certificate, agrees that it will look
solely to the Trust Fund and certain amounts resulting from credit enhancements
for payment hereunder and that the Trustee is not liable to the Holders for any
amount payable under this Certificate or the Agreement or, except as expressly
provided in the Agreement, subject to any liability under the Agreement.

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

     No service charge will be made to the Holder for any transfer or exchange
of the Certificate, but the Trustee may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer or exchange of the Certificate. Prior to due presentation of a
Certificate for registration of transfer, the Depositor and the Trustee may
treat the person in whose name any Certificate is registered as the owner of
such Certificate and the Percentage Interest in the Trust Fund evidenced thereby
for the purpose of receiving distributions pursuant to the Agreement and for all
other purposes whatsoever, and neither the Depositor nor the Trustee will be
affected by notice to the contrary.

     The Agreement may be amended from time to time by the Depositor, the
Servicer and the Trustee, without the consent of any of the Certificateholders,
to cure any ambiguity, to correct or supplement any provisions therein which may
be inconsistent with the other provisions therein, to ensure continuing
treatment of each REMIC included in the Trust Fund as a REMIC, or to make any
other provisions with respect to matters or questions arising under the
Agreement which are not materially inconsistent with the provisions of the
Agreement, provided that such action does not, as evidenced by an Opinion of
Counsel, adversely affect in any material respect the interests of any
Certificateholder.

     The Agreement may also be amended from time to time by the Depositor, the
Servicer and the Trustee, with the consent of the Holders of Certificates
evidencing in the aggregate not

                                      A-14

<PAGE>

less than 66 2/3% of the Percentage Interests of each Class of Certificates
affected thereby, for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of the Agreement or of modifying in
any manner the rights of the Holders of Certificates of such Class; provided,
however, that no such amendment may (i) reduce in any manner the amount of, or
delay the timing of, payments received on Mortgage Loans which are required to
be distributed on any Certificate without the consent of the Holder of such
Certificate, (ii) adversely affect in any material respect the interests of the
Holders of any Class of Certificates in a manner other than as described in
clause (i), without the consent of the Holders of Certificates of such Class
evidencing 66 2/3% or more of the Voting Rights of such Class or (iii) change
the percentage specified in clause (ii) of the third paragraph of Section 10.01
of the Agreement, without the consent of the Holders of all Certificates of such
Class then outstanding.

     The Class M-[_____] Certificates are issuable only in registerable form, in
minimum denominations of $25,000 in initial Certificate Principal Amount and in
integral multiples of $1 in excess thereof, registered in the name of the
nominee of the Clearing Agency, which shall maintain such Certificates through
its book-entry facilities.

     For federal income tax purposes, the Trust Fund will include multiple "real
estate mortgage investment conduits" (each, a "REMIC") in a tiered REMIC
structure. The REMIC Regular Interests will represent "regular interests" in one
of the REMICs included in the Trust Fund. The Class R Certificate will represent
the sole class of "residual interest" in each of the REMICs.

     The obligations and responsibilities of the Depositor, the Servicer and the
Trustee under the Agreement shall terminate upon the earlier of (a) the exercise
by the Trustee of an Optional Termination; and (b) the later of (i) the maturity
or other liquidation (or any Advance with respect thereto) of the last Mortgage
Loan remaining in the Trust Fund and the disposition of all REO Property and
(ii) the distribution to Certificateholders of all amounts required to be
distributed to them pursuant to this Agreement, as applicable. In no event shall
the trusts created under the Agreement continue beyond the earlier of (i) the
expiration of 21 years from the death of the last survivor of the descendants of
Joseph P. Kennedy, the late Ambassador of the United States to the Court of St.
James's, living on the date hereof and (ii) the Latest Possible Maturity Date.

                                 Series 2006-HE6

evidencing an ownership interest in distributions allocable to the Class
B-[_____] Certificates with respect to a pool of conventional, sub-prime
mortgage loans formed and sold by

                     MERRILL LYNCH MORTGAGE INVESTORS, INC.

     Unless this Certificate is presented by an authorized representative of the
Depository Trust Company, a New York corporation ("DTC"), to the Trustee for
registration of transfer, exchange or payment, and any certificate issued is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC (and any payment is made to Cede & Co. or to
such other entity as is requested by an authorized representative of DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co. has an interest
herein.

     This certifies that CEDE & CO. is the registered owner of the ownership
interest (the "Ownership Interest") evidenced by this Certificate (obtained by
dividing the Original Denomination of this Certificate by the aggregate Initial
Certificate Balance of all Class A Certificates) in certain distributions with
respect to a pool of conventional, sub-prime mortgage loans (the "Mortgage
Loans") formed and sold by Merrill Lynch Mortgage Investors, Inc. (hereinafter
called the "Depositor"), and certain other property held in trust for the
benefit of Certificateholders (collectively, the "Trust Fund"). The Mortgage
Loans are serviced by Wilshire Credit Corporation (the "Servicer") and are
secured by first-lien or second-lien mortgages on Mortgaged Properties. The
Trust Fund was created pursuant to a pooling and servicing agreement (the
"Agreement"), dated as of December 1, 2006, between the Depositor, the Servicer
and LaSalle Bank National Association, as trustee (the "Trustee"), a summary of
certain of the pertinent provisions of which is set forth hereafter. To the
extent not defined herein, the capitalized terms used herein have the meanings
assigned in the Agreement.

     This Certificate is one of a duly authorized issue of Certificates,
designated as Merrill Lynch Mortgage Investors Trust, Mortgage Loan Asset-Backed
Certificates, Series 2006-HE6, Class B-[_____] (the "Class B-[_____]
Certificates") and is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which Agreement such Holder is
bound.

     The Class A Certificates, the Class M Certificates, the Class B
Certificates, the Class P Certificates and the Class C Certificates are
collectively referred to herein as the "Certificates."

     Pursuant to the terms of the Agreement, the Trustee will distribute from
funds in the Certificate Account the amounts described in the Agreement on the
25th day of each month or, if such 25th day is not a Business Day, the Business
Day immediately following (the "Distribution Date"), commencing in January 2007.
Such distributions will be made to the Person in whose name this Certificate is
registered at the close of business on the last Business Day of the month
preceding the month in which such payment is made.

                                      A-19

<PAGE>

     Distributions on this Certificate will be made either by check mailed to
the address of the person entitled to distributions as it appears on the
Certificate Register or, in the case of any Certificateholder that has so
notified the Trustee in writing in accordance with the Agreement, by wire
transfer in immediately available funds to the account of such Certificateholder
at a bank or other depository institution having appropriate wire transfer
facilities; provided, however, that the final distribution in retirement of the
certificates will be made only upon presentation and surrender of this
Certificate at the office of the Trustee or such other address designated in
writing by the Trustee. On each Distribution Date, a Holder of this Certificate
will receive such Holder's Percentage Interest of the amounts required to be
distributed with respect to the applicable Class of Certificates.

     The Trustee will maintain or cause to be maintained a Certificate Register
in which, subject to such reasonable regulations as it may prescribe, the
Trustee will provide for the registration of Certificates and of transfers and
exchanges of Certificates. Upon surrender for registration of transfer of any
Certificate at any office or agency of the Trustee, or, if an Authenticating
Agent has been appointed under the Agreement, the Authenticating Agent,
maintained for such purpose, the Trustee, will, subject to the limitations set
forth in the Agreement, authenticate and deliver, in the name of the designated
transferee or transferees, a Certificate of a like class and dated the date of
authentication by the Authenticating Agent. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the Trustee,
of the pendency of such distribution and only upon presentation and surrender of
this Certificate at the office or agency appointed by the Trustee, for that
purpose and specified in such notice of final distribution.

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

     Unless the certificate of authentication has been executed by the
Authenticating Agent, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

                                      A-20

     IN WITNESS WHEREOF, the Trustee has caused this Certificate to be duly

                                 SERIES 2006-HE6

     This Certificate is one of a duly authorized issue of Certificates,

Certificates, Class M Certificates, Class B Certificates, Class P Certificates
and Class C Certificates, each evidencing an interest in certain distributions
with respect to a pool of conventional, sub-prime Mortgage Loans formed and sold
by the Depositor and certain other property conveyed by the Depositor to the
Trustee.

     Following the initial issuance of the Certificates, the principal balance
of this Certificate will be different from the Original Denomination shown
above. Anyone acquiring this Certificate may ascertain its current principal
balance by inquiry of the Trustee.

     The Holder, by its acceptance of this Certificate, agrees that it will look
solely to the Trust Fund and certain amounts resulting from credit enhancements
for payment hereunder and that the Trustee is not liable to the Holders for any
amount payable under this Certificate or the Agreement or, except as expressly
provided in the Agreement, subject to any liability under the Agreement.

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

     No service charge will be made to the Holder for any transfer or exchange
of the Certificate, but the Trustee may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer or exchange of the Certificate. Prior to due presentation of a
Certificate for registration of transfer, the Depositor and the Trustee may
treat the person in whose name any Certificate is registered as the owner of
such Certificate and the Percentage Interest in the Trust Fund evidenced thereby
for the purpose of receiving distributions pursuant to the Agreement and for all
other purposes whatsoever, and neither the Depositor nor the Trustee will be
affected by notice to the contrary.

     The Agreement may be amended from time to time by the Depositor, the
Servicer and the Trustee, without the consent of any of the Certificateholders,
to cure any ambiguity, to correct or supplement any provisions therein which may
be inconsistent with the other provisions therein, to ensure continuing
treatment of each REMIC included in the Trust Fund as a REMIC, or to make any
other provisions with respect to matters or questions arising under the
Agreement which are not materially inconsistent with the provisions of the
Agreement, provided that such action does not, as evidenced by an Opinion of
Counsel, adversely affect in any material respect the interests of any
Certificateholder.

     The Agreement may also be amended from time to time by the Depositor, the
Servicer and the Trustee with the consent of the Holders of Certificates
evidencing in the aggregate not

                                      A-22

less than 66 2/3% of the Percentage Interests of each Class of Certificates
affected thereby for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of the Agreement or of modifying in
any manner the rights of the Holders of Certificates of such Class; provided,
however, that no such amendment may (i) reduce in any manner the amount of, or
delay the timing of, payments received on Mortgage Loans which are required to
be distributed on any Certificate without the consent of the Holder of such
Certificate, (ii) adversely affect in any material respect the interests of the
Holders of any Class of Certificates in a manner other than as described in
clause (i), without the consent of the Holders of Certificates of such Class
evidencing 66 2/3% or more of the Voting Rights of such Class or (iii) change
the percentage specified in clause (ii) of the third paragraph of Section 10.01
of the Agreement, without the consent of the Holders of all Certificates of such
Class then outstanding.

     The Class B-[_____] Certificates are issuable only in registerable form, in
minimum denominations of $25,000 in initial Certificate Principal Amount and in
integral multiples of $1 in excess thereof, registered in the name of the
nominee of the Clearing Agency, which shall maintain such Certificates through
its book-entry facilities.

     For federal income tax purposes, the Trust Fund will include multiple "real
estate mortgage investment conduits" (each, a "REMIC") in a tiered REMIC
structure. The REMIC Regular Interests will represent "regular interests" in one
of the REMICs included in the Trust Fund. The Class R Certificate will represent
the sole class of "residual interest" in each of the REMICs.

     The obligations and responsibilities of the Depositor, the Servicer and the

or other liquidation (or any Advance with respect thereto) of the last Mortgage
Loan remaining in the Trust Fund and the disposition of all REO Property and

distributed to them pursuant to this Agreement, as applicable. In no event shall
the trusts created under the Agreement continue beyond the earlier of (i) the
expiration of 21 years from the death of the last survivor of the descendants of
Joseph P. Kennedy, the late Ambassador of the United States to the Court of St.
James's, living on the date hereof and (ii) the Latest Possible Maturity Date.

formed and sold by

                     MERRILL LYNCH MORTGAGE INVESTORS, INC.

     This certifies that MERRILL LYNCH, PIERCE, FENNER & SMITH INCORPORATED, as
nominee for Merrill Lynch Funding Corp, is the registered owner of the ownership
interest (the "Ownership Interest") evidenced by this Certificate (obtained by
dividing the Original Denomination of this Certificate by the aggregate Initial
Certificate Balance of all Class C Certificates) in certain distributions with
respect a pool of conventional, sub-prime mortgage loans (the "Mortgage Loans")
formed and sold by Merrill Lynch Mortgage Investors, Inc. (hereinafter called
the "Depositor"), and certain other property held in trust for the benefit of
Certificateholders (collectively, the "Trust Fund"). The Mortgage Loans are
serviced by Wilshire Credit Corporation (the "Servicer") and are secured by
first or second-lien mortgages on the Mortgaged Properties. The Trust Fund was
created pursuant to a pooling and servicing agreement (the "Agreement"), dated
as of December 1, 2006, among the Depositor, the Servicer and LaSalle Bank
National Association, as trustee (the "Trustee"), a summary of certain of the
pertinent provisions of which is set forth hereafter. To the extent not defined
herein, the capitalized terms used herein have the meanings assigned in the
Agreement.

     This Certificate is one of a duly authorized issue of Certificates,
designated as Merrill Lynch Mortgage Investors Trust Mortgage Loan Asset-Backed
Certificates, Series 2006-HE6, Class C (the "Class C Certificates") and is
issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Certificate by virtue of the
acceptance hereof assents and by which Agreement such Holder is bound.

     The Class A Certificates, the Class M Certificates, the Class B
Certificates, the Class P Certificates and the Class C Certificates are
collectively referred to herein as the "Certificates."

     Pursuant to the terms of the Agreement, the Trustee will distribute from
funds in the Certificate Account the amounts described in the Agreement on the
25th day of each month or, if such 25th day is not a Business Day, the Business
Day immediately following (the "Distribution Date"), commencing in January 2007.
Such distributions will be made to the Person in whose name this Certificate is
registered at the close of business on the last Business Day of the month
preceding the month in which such payment is made.

     Distributions on this Certificate will be made either by check mailed to
the address of the person entitled to distributions as it appears on the
Certificate Register or, in the case of any certificateholder that has so
notified the Trustee in writing in accordance with the Agreement, by wire
transfer in immediately available funds to the account of such certificateholder
at a bank or other depository institution having appropriate wire transfer
facilities; provided, however, that the final distribution in retirement of the
certificates will be made only upon presentation and surrender of this
Certificate at the office of the Trustee or such other address designated in

                                      A-27

writing by the Trustee. On each Distribution Date, a holder of this Certificate
will receive such holder's Percentage Interest of the amounts required to be
distributed with respect to the applicable Class of Certificates.

     The Trustee will maintain or cause to be maintained a Certificate Register
in which, subject to such reasonable regulations as it may prescribe, the
Trustee will provide for the registration of Certificates and of transfers and
exchanges of Certificates. Upon surrender for registration of transfer of any
Certificate at any office or agency of the Trustee, or, if an Authenticating
Agent has been appointed under the Agreement, the Authenticating Agent,
maintained for such purpose, the Trustee, will, subject to the limitations set
forth in the Agreement, authenticate and deliver, in the name of the designated
transferee or transferees, a Certificate of a like class and dated the date of
authentication by the Authenticating Agent. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the Trustee,
of the pendency of such distribution and only upon presentation and surrender of
this Certificate at the office or agency appointed by the Trustee, for that
purpose and specified in such notice of final distribution.

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

     Unless the certificate of authentication has been executed by the
Authenticating Agent, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

                    MORTGAGE LOAN ASSET-BACKED CERTIFICATES,
                                 Series 2006-HE6

     This Certificate is one of a duly authorized issue of Certificates,
designated as Merrill Lynch Mortgage Investors Trust Mortgage Loan Asset-Backed
Certificates, Series 2006-HE6, issued in one or more Classes of Class A
Certificates, Class M Certificates, Class B Certificates, Class P Certificates
and Class C Certificates, each evidencing an interest in certain distributions
with respect to a pool of conventional, sub-prime Mortgage Loans formed and sold
by the Depositor and certain other property conveyed by the Depositor to the
Trustee.

     Following the initial issuance of the Certificates, the principal balance
of this Certificate will be different from the Original Denomination shown
above. Anyone acquiring this Certificate may ascertain its current principal
balance by inquiry of the Trustee.

     The Holder, by its acceptance of this Certificate, agrees that it will look
solely to the Trust Fund and certain amounts resulting from credit enhancements
for payment hereunder and that the Trustee is not liable to the Holders for any
amount payable under this Certificate or the Agreement or, except as expressly
provided in the Agreement, subject to any liability under the Agreement.

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

     No service charge will be made to the Holder for any transfer or exchange
of the Certificate, but the Trustee may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer or exchange of the Certificate. Prior to due presentation of a
Certificate for registration of transfer, the Depositor and the Trustee may
treat the person in whose name any Certificate is registered as the owner of
such Certificate and the Percentage Interest in the Trust Fund evidenced thereby
for the purpose of receiving distributions pursuant to the Agreement and for all
other purposes whatsoever, and neither the Depositor nor the Trustee will be
affected by notice to the contrary.

     The Agreement may be amended from time to time by the Depositor, the
Servicer and the Trustee, without the consent of any of the Certificateholders,
to cure any ambiguity, to correct or supplement any provisions therein which may
be inconsistent with the other provisions therein, to ensure continuing
treatment of each REMIC included in the Trust Fund as a REMIC, or to make any
other provisions with respect to matters or questions arising under the
Agreement which are not materially inconsistent with the provisions of the
Agreement, provided that such action does not, as evidenced by an Opinion of
Counsel, adversely affect in any material respect the interests of any
Certificateholder.

     The Agreement may also be amended from time to time by the Depositor, the
Servicer and the Trustee, with the consent of the Holders of Certificates
evidencing in the aggregate not less than 66 2/3% of the Percentage Interests of
each Class of Certificates affected thereby, for

                                      A-30

<PAGE>

the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Agreement or of modifying in any manner the rights
of the Holders of Certificates of such Class; provided, however, that no such
amendment may (i) reduce in any manner the amount of, or delay the timing of,
payments received on Mortgage Loans which are required to be distributed on any
Certificate without the consent of the Holder of such Certificate, (ii)
adversely affect in any material respect the interests of the Holders of any
Class of Certificates in a manner other than as described in clause (i), without
the consent of the Holders of Certificates of such Class evidencing 66 2/3% or
more of the Voting Rights of such Class or (iii) change the percentage specified
in clause (ii) of the third paragraph of Section 10.01 of the Agreement, without
the consent of the Holders of all Certificates of such Class then outstanding.

     For federal income tax purposes, the Trust Fund will include multiple "real
estate mortgage investment conduits" (each, a "REMIC") in a tiered REMIC
structure. The REMIC Regular Interests will represent "regular interests" in one
of the REMICs included in the Trust Fund. The Class R Certificate will represent
the sole class of "residual interest" in each of the REMICs.

     The obligations and responsibilities of the Depositor, the Servicer and the
Trustee under the Agreement shall terminate upon the earlier of (a) the exercise
by the Trustee of an Optional Termination; and (b) the later of (i) the maturity
or other liquidation (or any Advance with respect thereto) of the last Mortgage
Loan remaining in the Trust Fund and the disposition of all REO Property and
(ii) the distribution to Certificateholders of all amounts required to be
distributed to them pursuant to this Agreement, as applicable. In no event shall
the trusts created under the Agreement continue beyond the earlier of (i) the
expiration of 21 years from the death of the last survivor of the descendants of
Joseph P. Kennedy, the late Ambassador of the United States to the Court of St.
James's, living on the date hereof and (ii) the Latest Possible Maturity Date.

                     MERRILL LYNCH MORTGAGE INVESTORS TRUST
                    MORTGAGE LOAN ASSET-BACKED CERTIFICATES,
                                 Series 2006-HE6

evidencing an ownership interest in distributions allocable to the Class R
Certificates with respect to a pool of conventional, sub-prime mortgage loans
formed and sold by

                     MERRILL LYNCH MORTGAGE INVESTORS, INC.

     This certifies that MERRILL LYNCH, PIERCE, FENNER & SMITH INCORPORATED, as
nominee for Merrill Lynch Funding Corporation, is the registered owner of the
ownership interest (the "Ownership Interest") evidenced by this Certificate
(obtained by dividing the Original Denomination of this Certificate by the
aggregate Initial Certificate Balance of all Class R Certificates) in certain
distributions with respect to a pool of conventional, sub-prime mortgage loans
(the "Mortgage Loans") formed and sold by Merrill Lynch Mortgage Investors, Inc.
(hereinafter called the "Depositor"), and certain other property held in trust
for the benefit of Certificateholders (collectively, the "Trust Fund"). The
Mortgage Loans are serviced by Wilshire Credit Corporation (the "Servicer") and
are secured by first or second-lien mortgages on the Mortgaged Properties. The
Trust Fund was created pursuant to a pooling and servicing agreement (the
"Agreement"), dated as of December 1, 2006, among the Depositor, the Servicer
and LaSalle Bank National Association, as trustee (the "Trustee"), a summary of
certain of the pertinent provisions of which is set forth hereafter. To the
extent not defined herein, the capitalized terms used herein have the meanings
assigned in the Agreement.

     This Certificate is one of a duly authorized issue of Certificates,
designated as Merrill Lynch Mortgage Investors Trust Mortgage Loan Asset-Backed
Certificates, Series 2006-HE6, Class R (the "Class R Certificate") and is
issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Certificate by virtue of the
acceptance hereof assents and by which Agreement such Holder is bound.

     The Class A Certificates, the Class M Certificates, the Class B
Certificates, the Class P Certificates and the Class C Certificates are
collectively referred to herein as the "Certificates."

     Pursuant to the terms of the Agreement, the Trustee will distribute from
funds in the Certificate Account the amounts described in the Agreement on the
25th day of each month or, if such 25th day is not a Business Day, the Business
Day immediately following (the "Distribution Date"), commencing in January 2007.
Such distributions will be made to the Person in whose name this Certificate is
registered at the close of business on the last Business Day of the month
preceding the month in which such payment is made.

     Distributions on this Certificate will be made either by check mailed to
the address of the person entitled to distributions as it appears on the
Certificate Register or, in the case of any certificateholder that has so
notified the Trustee in writing in accordance with the Agreement, by wire
transfer in immediately available funds to the account of such certificateholder
at a bank or other depository institution having appropriate wire transfer
facilities; provided, however, that the final distribution in retirement of the
certificates will be made only upon presentation and

                                      A-42

<PAGE>

surrender of this Certificate at the office of the Trustee or such other address
designated in writing by the Trustee. On each Distribution Date, a holder of
this Certificate will receive such holder's Percentage Interest of the amounts
required to be distributed with respect to the applicable Class of Certificates.

     The Trustee will maintain or cause to be maintained a Certificate Register
in which, subject to such reasonable regulations as it may prescribe, the
Trustee will provide for the registration of Certificates and of transfers and
exchanges of Certificates. Upon surrender for registration of transfer of any
Certificate at any office or agency of the Trustee, or, if an Authenticating
Agent has been appointed under the Agreement, the Authenticating Agent,
maintained for such purpose, the Trustee, will, subject to the limitations set
forth in the Agreement, authenticate and deliver, in the name of the designated
transferee or transferees, a Certificate of a like class and dated the date of
authentication by the Authenticating Agent. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the Trustee,
of the pendency of such distribution and only upon presentation and surrender of
this Certificate at the office or agency appointed by the Trustee, for that
purpose and specified in such notice of final distribution.

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

     Unless the certificate of authentication has been executed by the
Authenticating Agent, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

                                      A-43

     IN WITNESS WHEREOF, the Trustee has caused this Certificate to be duly

                             REVERSE OF CERTIFICATE

                     MERRILL LYNCH MORTGAGE INVESTORS TRUST
                    MORTGAGE LOAN ASSET-BACKED CERTIFICATES,
                                 Series 2006-HE6

     This Certificate is one of a duly authorized issue of Certificates,
designated as Merrill Lynch Mortgage Investors Trust Mortgage Loan Asset-Backed
Certificates, Series 2006-HE6, issued in one or more Classes of Class A
Certificates, Class M Certificates, Class B Certificates, Class P Certificates
and Class C Certificates, each evidencing an interest in certain distributions
with respect to pools of conventional, sub-prime Mortgage Loans formed and sold
by the Depositor and certain other property conveyed by the Depositor to the
Trustee.

     Following the initial issuance of the Certificates, the principal balance
of this Certificate will be different from the Original Denomination shown
above. Anyone acquiring this Certificate may ascertain its current principal
balance by inquiry of the Trustee.

     The Holder, by its acceptance of this Certificate, agrees that it will look
solely to the Trust Fund and certain amounts resulting from credit enhancements
for payment hereunder and that the Trustee is not liable to the Holders for any
amount payable under this Certificate or the Agreement or, except as expressly
provided in the Agreement, subject to any liability under the Agreement.

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

     No service charge will be made to the Holder for any transfer or exchange
of the Certificate, but the Trustee may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer or exchange of the Certificate. Prior to due presentation of a
Certificate for registration of transfer, the Depositor and the Trustee may
treat the person in whose name any Certificate is registered as the owner of
such Certificate and the Percentage Interest in the Trust Fund evidenced thereby
for the purpose of receiving distributions pursuant to the Agreement and for all
other purposes whatsoever, and neither the Depositor nor the Trustee will be
affected by notice to the contrary.

     The Agreement may be amended from time to time by the Depositor, the
Servicer and the Trustee, without the consent of any of the Certificateholders,
to cure any ambiguity, to correct or supplement any provisions therein which may
be inconsistent with the other provisions therein, to ensure continuing
treatment of each REMIC included in the Trust Fund as a REMIC, or to make any
other provisions with respect to matters or questions arising under the
Agreement which are not materially inconsistent with the provisions of the
Agreement, provided that such action does not, as evidenced by an Opinion of
Counsel, adversely affect in any material respect the interests of any
Certificateholder.

     The Agreement may also be amended from time to time by the Depositor, the
Servicer and the Trustee, with the consent of the Holders of Certificates
evidencing in the aggregate not

                                      A-45

<PAGE>

less than 66 2/3% of the Percentage Interests of each Class of Certificates
affected thereby, for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of the Agreement or of modifying in
any manner the rights of the Holders of Certificates of such Class; provided,
however, that no such amendment may (i) reduce in any manner the amount of, or
delay the timing of, payments received on Mortgage Loans which are required to
be distributed on any Certificate without the consent of the Holder of such
Certificate, (ii) adversely affect in any material respect the interests of the
Holders of any Class of Certificates in a manner other than as described in
clause (i), without the consent of the Holders of Certificates of such Class
evidencing 66 2/3% or more of the Voting Rights of such Class or (iii) change
the percentage specified in clause (ii) of the third paragraph of Section 10.01
of the Agreement, without the consent of the Holders of all Certificates of such
Class then outstanding.

     For federal income tax purposes, the Trust Fund will include multiple "real
estate mortgage investment conduits" (each, a "REMIC") in a tiered REMIC
structure. The REMIC Regular Interests will represent "regular interests" in one
of the REMICs included in the Trust Fund. The Class R Certificate will represent
the sole class of "residual interest" in each of the REMICs.

     The obligations and responsibilities of the Depositor, the Servicer and the
Trustee under the Agreement shall terminate upon the earlier of (a) the exercise
by the Trustee of an Optional Termination; and (b) the later of (i) the maturity
or other liquidation (or any Advance with respect thereto) of the last Mortgage
Loan remaining in the Trust Fund and the disposition of all REO Property and
(ii) the distribution to Certificateholders of all amounts required to be
distributed to them pursuant to this Agreement, as applicable. In no event shall
the trusts created under the Agreement continue beyond the earlier of (i) the
expiration of 21 years from the death of the last survivor of the descendants of
Joseph P. Kennedy, the late Ambassador of the United States to the Court of St.
James's, living on the date hereof and (ii) the Latest Possible Maturity Date.

Attention: Merrill Lynch Mortgage Investors Trust, Series 2006-HE6

Ladies and Gentlemen:

     We propose to purchase Merrill Lynch Mortgage Investors Trust, Mortgage
Loan Asset-Backed Certificates, Series 2006-HE6, Class R, described in the
Prospectus Supplement, dated December 21, 2006, and the Prospectus, dated
September 8, 2006.

     1. We certify that (a) we are not a disqualified organization and (b) we
are not purchasing such Class R Certificate on behalf of a disqualified
organization; for this purpose the term "disqualified organization" means the
United States, any state or political subdivision thereof, any foreign
government, any international organization, any agency or instrumentality of any
of the foregoing (except any entity treated as other than an instrumentality of
the foregoing for purposes of Section 168(h)(2)(D) of the Internal Revenue Code
of 1986, as amended (the "Code")), any organization (other than a cooperative
described in Section 521 of the Code) that is exempt from taxation under the
Code (unless such organization is subject to tax on excess inclusions) and any
organization that is described in Section 1381(a)(2)(C) of the Code. We
understand that any breach by us of this certification may cause us to be liable
for an excise tax imposed upon transfers to disqualified organizations.

     2. We certify that (a) we have historically paid our debts as they became
due, (b) we intend, and believe that we will be able, to continue to pay our
debts as they become due in the future, (c) we understand that, as beneficial
owner of the Class R Certificate, we may incur tax liabilities in excess of any
cash flows generated by the Class R Certificate, and (d) we intend to pay any
taxes associated with holding the Class R Certificate as they become due and (e)
we will not cause income from the Class R Certificate to be attributable to a
foreign permanent establishment or fixed base (within the meaning of an
applicable income tax treaty) of ours or another U.S. taxpayer.

                                      E-1-1

<PAGE>

     3. We acknowledge that we will be the beneficial owner of the Class R
Certificate and:(5)

     __________ The Class R Certificate will be registered in our name.
     __________ The Class R Certificate will be held in the name of our nominee,
                __________, which is not a disqualified organization.

     4. We certify that we are not an employee benefit plan subject to Title I
of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), a
plan subject to Section 4975 of the Code or a plan subject to federal, state,
local, non-U.S. or other law substantively similar to the foregoing provisions
of ERISA or the Code (each, a "Plan"), and are not directly or indirectly
acquiring the Class R Certificate on behalf of or with any assets of a Plan.

     5. We certify that (i) we are a U.S. person or (ii) we will hold the Class
R Certificate in connection with the conduct of a trade or business within the
United States and have furnished the transferor and the Trustee with a duly
completed and effective Internal Revenue Service Form W-8ECI or successor form
at the time and in the manner required by the Code; for this purpose the term
"U.S. person" means a citizen or resident of the United States, a corporation,
or partnership (unless, in the case of a partnership, Treasury regulations are
adopted that provide otherwise) created or organized in or under the laws of the
United States, any State thereof or the District of Columbia, including an
entity treated as a corporation or partnership for federal income tax purposes,
an estate whose income is subject to United States federal income tax regardless
of the source of its income, or a trust if a court within the United States is
able to exercise primary supervision over the administration of the trust and
one or more such U.S. persons have the authority to control all substantial
decisions of the trust (or, to the extent provided in applicable Treasury
regulations, certain trusts in existence on August 20, 1996 which are eligible
to elect to be treated as U.S. Persons. We agree that any breach by us of this
certification shall render the transfer of any interest in the Class R
Certificate to us absolutely null and void and shall cause no rights in the

                                        Affidavit pursuant to (i) Section
                                        860E(e)(4) of the Internal Revenue Code
                                        of 1986, as amended, and (ii) certain
                                        provisions of the Pooling and Servicing
                                        Agreement

Under penalties of perjury, the undersigned declares that the following is true:

     1. He or she is an officer of _________________________ (the "Transferee"),

     2. the Transferee's Employer Identification number is __________,

     3. the Transferee is not a "disqualified organization" (as defined below),
has no plan or intention of becoming a disqualified organization, and is not
acquiring any of its interest in the Merrill Lynch Mortgage Investors Trust,
Mortgage Loan Asset-Backed Certificates, Series 2006-HE6, Class R Certificate on
behalf of a disqualified organization or any other entity,

     4. unless Merrill Lynch Mortgage Investors, Inc.("MLMI") has consented to
the transfer to the Transferee by executing the form of Consent affixed as
Appendix B to the Transferee's Letter to which this Certificate is affixed as
Appendix A, the Transferee is a "U.S. person" (as defined below),

     5. that no purpose of the transfer is to avoid or impede the assessment or
collection of tax,

     6. the Transferee has historically paid its debts as they became due,

     7. the Transferee intends, and believes that it will be able, to continue
to pay its debts as they become due in the future,

     8. the Transferee understands that, as beneficial owner of the Class R
Certificate, it may incur tax liabilities in excess of any cash flows generated
by the Class R Certificate,

     9. the Transferee intends to pay any taxes associated with holding the
Class R Certificate as they become due,

     10. the Transferee consents to any amendment of the Pooling and Servicing
Agreement that shall be deemed necessary by MLMI (upon advice of counsel) to
constitute a reasonable arrangement to ensure that the Class R Certificate will
not be owned directly or indirectly by a disqualified organization, and

     11. IF BRACKETED, THE FOLLOWING CERTIFICATIONS ARE INAPPLICABLE [the
transfer is not a direct or indirect transfer of the Class R Certificate to a
foreign permanent establishment or fixed base (within the meaning of an
applicable income tax treaty) of the Transferee, and as to each of the residual
interests represented by the Class R Certificate, the present value of the
anticipated tax liabilities associated with holding such residual interest does
not exceed the sum of:

     A. the present value of any consideration given to the Transferee to
acquire such residual interest;

                                      E-1-4

<PAGE>

     B. the present value of the expected future distributions on such residual
interest; and

     C. the present value of the anticipated tax savings associated with holding
such residual interest as the related REMIC generates losses.

For purposes of this declaration, (i) the Transferee is assumed to pay tax at a
rate equal to the highest rate of tax specified in Section 11(b)(1) of the Code,
but the tax rate specified in Section 55(b)(1)(B) of the Code may be used in
lieu of the highest rate specified in Section 11(b)(1) of the Code if the
Transferee has been subject to the alternative minimum tax under Section 55 of
the Code in the preceding two years and will compute its taxable income in the
current taxable year using the alternative minimum tax rate, and (ii) present
values are computed using a discount rate equal to the Federal short-term rate
prescribed by Section 1274(d) of the Code for the month of the transfer and the
compounding period used by the Transferee;]

[(11) (A) at the time of the transfer, and at the close of each of the
     Transferee's two fiscal years preceding the Transferee's fiscal year of
     transfer, the Transferee's gross assets for financial reporting purposes
     exceed $100 million and its net assets for financial reporting purposes
     exceed $10 million; and

     (B)  the Transferee is an eligible corporation as defined in Treasury
          regulations Section 1.860E-1(c)(6)(i) and has agreed in writing that
          any subsequent transfer of the Class R Certificate will be to another
          eligible corporation in a transaction that satisfies Treasury
          regulation Sections 1.860E-1(c)(4)(i), 1.860E-1(c)(4)(ii),
          1.860E-1(c)(4)(iii) and 1.860E-1(c)(5) and such transfer will not be a
          direct or indirect transfer to a foreign permanent establishment
          (within the meaning of an applicable income tax treaty) of a domestic
          corporation.

For purposes of this declaration, the gross and net assets of the Transferee do
not include any obligation of any related person as defined in Treasury
regulation Section 1.860E-1(c)(6)(ii) or any other asset if a principal purpose
for holding or acquiring the other asset is to permit the Transferee to make
this declaration or to satisfy the requirements of Treasury regulation Section
1.860E-1(c)(5)(i).]

(12) The Transferee will not cause income from the Class R Certificate to be
attributable to a foreign permanent establishment or fixed base (within the
meaning of an applicable income tax treaty) of the Transferee or another U.S.
taxpayer.

For purpose of this affidavit, the term "disqualified organization" means the
United States, any state or political subdivision thereof, any foreign
government, any international organization, any agency or instrumentality of any
of the foregoing (except any entity treated as other than an instrumentality of
the foregoing for purposes of Section 168(h)(2)(D) of the Internal Revenue Code
of 1986, as amended (the "Code")), any organization (other than a cooperative
described in Section 521 of the Code) that is exempt from taxation under the
Code (unless such organization is subject to tax on excess inclusions) and any
organization that is described in Section 1381(a)(2)(C) of the Code and the term
"U.S. Person" means a citizen or resident of the United States, a corporation or
partnership (unless, in the case of a partnership, Treasury regulations are
adopted that provide otherwise) created or organized in or under the laws of the
United States, any state thereof or the District of Columbia, including an

of its source, or a trust if a court within the United States is able to
exercise primary

     _______________________ (the "Transferor") has reviewed the attached
affidavit of _____________________________ (the "Transferee"), and has no actual
knowledge that such affidavit is not true, and has no reason to believe that the
Transferee has the intention to impede the assessment or collection of any

Transferor has conducted a reasonable investigation at the time of the transfer
and found that the Transferee had historically paid its debts as they came due
and found no significant evidence to indicate that the Transferee will not
continue to pay its debts as they become due.

                              TERMS AND CONDITIONS

1.   DEFINITIONS

1.1  APPLICATION means a request for coverage, including assumption of coverage,
     under this Policy for a Loan on a form or in a format provided by the
     Company, and all other statements, documents, or information furnished to
     the Company by the Insured or any other Person in connection with the
     insuring of the Loan. An Application will include information, if so
     furnished to the Company, contained in the Borrower's Loan application,
     appraisal, verifications of income and deposit, plans and specifications
     for the Property, and all other exhibits and documents, and will include
     all data and information so furnished by electronic means.

1.2  APPROPRIATE PROCEEDINGS means any legal or administrative action by the
     Insured affecting either a Loan or title to a Property, including:

     a.   Preserving a deficiency recovery by making a bid at the foreclosure
          sale and pursuing a deficiency judgment until the end of the
          Settlement Period, where appropriate and permissible and where
          directed by the Company; or

     b.   Enforcing the terms of the Loan as allowed by the law where the
          Property is located; or

     c.   Acquiring Borrower's Title or Good and Merchantable Title to the
          Property, as either may be required under this Policy, but excluding
          such title as may be acquired by a voluntary conveyance from the
          Borrower; or

     d.   Asserting the Insured's interest in the Property in a Borrower's
          bankruptcy.

1.3  BORROWER means any Person legally obligated to repay the debt obligation
     created by a Loan, including any co-signer or guarantor of the Loan.

1.4  BORROWER'S TITLE means such title to a Property as was vested in the
     Borrower at the time of a conveyance to the Insured arising out of or
     pursuant to a foreclosure of the Loan; provided, however, if the Insured so
     elects, the redemption period need not have expired. Borrower's Title in
     the Insured may be, but need not be, the equivalent of Good and
     Merchantable Title, and the deed evidencing Borrower's Title need not be
     recorded unless required by applicable law.

1.5  CERTIFICATE means the document, which may be on the same form as the
     Commitment, issued by the Company pursuant to this Policy and extending the
     coverage indicated therein to a specified Loan.

1.6  CERTIFICATE EFFECTIVE DATE means, as specified in the Certificate, (a) the
     closing date of a Loan, or (b) the later date requested by the Insured and
     accepted by the Company.

1.7  CLAIM means the timely filed written request, made on a form or in a format
     provided or approved by the Company, to receive the benefits of this
     Policy.

1.8  CLAIM AMOUNT means the amount calculated in accordance with Section 6.2 of
     this Policy.

1.9  COMMITMENT means the document, which may be on the same form as the
     Certificate, issued by the Company evidencing the Company's offer to insure
     the Loan identified therein, subject to the terms and conditions therein
     and in this Policy.

MP-1103                                 2                                   8/94

<PAGE>

1.10 DEFAULT means the failure by a Borrower (a) to pay when due an amount equal
     to or greater than one (1) periodic monthly payment due under the terms of
     a Loan, or (b) to comply with any other term or condition of the Loan, if
     failure to comply is a basis for the acceleration of the principal balance
     of the Loan and the institution of Appropriate Proceedings.

     A Loan is deemed to be in Default for that month as of the close of
     business on the installment due date for which a scheduled monthly payment
     has not been made or as of the close of business on the date the Borrower
     fails to comply with any such other term or condition of the Loan. The Loan
     will be considered to remain in Default until filing of a Claim so long as
     such periodic payment has not been made or basis for acceleration and
     Appropriate Proceedings remains. For example, a Loan is "four (4) months in
     Default" if the monthly installments due on January 1 through April 1
     remain unpaid as of the close of business on April 1 or if a basis for
     acceleration and Appropriate Proceedings exists.

1.11 DEFICIENCY EXPENSES means reasonable attorney's fees and necessary court
     costs incurred by the Insured for those Appropriate Proceedings necessary
     to pursue or establish a deficiency against the Borrower and which are in
     addition to those incurred in standard and customary foreclosure
     proceedings, plus additional interest accruing on the Loan, real estate
     taxes, casualty insurance premiums, and Property preservation expenses
     incurred during such Appropriate Proceedings and any additional related
     redemption period as necessitated by such deficiency pursuit.

1.12 ENVIRONMENTAL CONDITION means the presence, on or under a Property, of any
     "Hazardous Substance" as that term is defined by the federal Comprehensive
     Environmental Response, Compensation and Liability Act (42 U.S.C. Sec. 9601
     et seq., as amended from time to time) or as defined by any similar state
     law; or any "Hazardous Waste" or "Regulated Substance" as those terms are
     defined by the federal Resource Conservation and Recovery Act (42 U.S.C.
     sec. 6901, et seq., as amended from time to time) or as defined by any
     similar state law, but does not mean the presence of radon, lead paint, or
     asbestos.

1.13 FAIR MARKET VALUE means, with regard to the amount bid for any Property at
     a foreclosure sale, the Property's value at the approximate time of the
     foreclosure sale as determined by appraisal if available or in accordance
     with customary servicing practices (which may include reliance on
     information provided by a local real estate broker), subject to applicable
     law governing foreclosure.

1.14 GOOD AND MERCHANTABLE TITLE means title to a Property free and clear of all
     liens, encumbrances, covenants, conditions, restrictions, encroachments,
     impediments, easements and rights of redemption, and other rights and
     claims of a Borrower or third parties except for:

     a.   A lien of any public bond, assessment, or tax, when no installment,
          call, or payment of or under such bond, assessment, or tax is
          delinquent;

     b.   Outstanding mineral, oil, or timber rights, rights of way, easements,
          rights of support, sewer rights, zoning ordinances, building
          restrictions or other restrictions, covenants, regulations of use, or
          applicable laws, provided the Property conforms to, and its intended
          and normal use and occupancy is not adversely affected by, such
          covenants, rights, restrictions, regulations, or ordinances; and

     c.   Any conditions or defects which will not have a materially adverse
          effect on either the transferability of the Property or the sale
          thereof to a bona fide purchaser.

MP-1103                                 3                                   8/94

     Good and Merchantable Title does not exist if convenient means of ingress
     and egress are not conveyed as well as freely alienable rights to the use
     and enjoyment of municipal or private sources of water and means of sewage
     disposal, whether such rights are by easement or covenant running with the
     Property are reflected in the public records relating to the Property.

     In addition, Good and Merchantable Title does not exist if notice has been
     given of the commencement of proceedings that could result in the
     imposition of a lien upon the Property pursuant to the Comprehensive
     Environmental Response, Compensation and Liability Act, as amended, 42
     U.S.C. 9601, et seq., or any other statute, law, or regulation of any
     governmental authority providing for the imposition of a lien in connection
     with the cleanup of Environmental Conditions.

1.15 INSURED means:

     a.   The Person designated on the face of this Policy; or

     Owner of the Loan.

1.16 LOAN means any note, bond, or other evidence of indebtedness secured by a
     mortgage, deed of trust, or other similar instrument, which constitutes or
     is equivalent to a first lien or charge on a Property and which the Company
     has approved for insurance and to which coverage under this Policy has been
     extended.

1.17 LOSS means the liability of the Company with respect to a Loan for payment
     of a Perfected Claim which is calculated in accordance with Section 6.3. A
     Loss will be deemed to have occurred when a Default on a Loan occurs, even
     though the amount of Loss is not then either presently ascertainable or due
     and payable.

1.18 OWNER OR OWNER OF THE LOAN means the Person who owns a Loan and of whom the
     Company is notified in accordance with this Policy.

2.   OBTAINING COVERAGE AND PAYMENT OF PREMIUMS

2.1  APPLICATION AND CERTIFICATE - In order to insure a Loan under this Policy,
     the Insured or a Person acting on behalf of the Insured must submit to the
     Company a properly completed Application. Approval of any Application will
     be at the discretion of the Company and will be in the form of a Commitment
     or a Certificate which offers to extend, or extends, coverage under the
     terms and conditions of both this Policy and the Commitment or Certificate,
     as the case may be.

     In lieu of such an Application and supporting statements, documents, and
     information submitted to the Company in connection with insuring a Loan,
     the Company may accept an alternative form of Application, containing more
     limited information, including certifications by or on behalf of the
     Insured as to characteristics of a Loan in lieu of supporting statements,
     documents, and information. The Company shall be entitled to rely fully on
     such alternative Application as submitted. Use of an alternative form of
     Application shall not waive or change the other terms and conditions of
     this Policy under which a Loan is insured or the responsibility of the
     Insured for the accuracy of statements, documents, and information
     submitted by it or other Persons to the Company as provided in this Policy.

     If the Company declines to insure a Loan, it will not issue a Commitment or
     Certificate, and it will notify the Insured in writing of such declination.
     If the Insured or the Person acting on its behalf subsequently denies the
     Loan application which it received from the applicant, the Insured or such
     Person will be responsible for notifying the applicant that the Company
     declined to insure the Loan. Such notification will be made in compliance
     with any applicable state or federal laws or regulations, including the
     Equal Credit Opportunity Act and any other similar law or regulation.

MP-1103                                 5                                   8/94

<PAGE>

2.2  REPRESENTATIONS OF THE INSURED - The Insured represents that:

     a.   All statements made and information provided to the Company in an
          Application or in any Commitment or Certificate (including any that is
          related to continuation of coverage upon assumption of a Loan),
          whether by it, the Borrower, or any other Person, have been made and
          presented for and on behalf of the Insured; and

     b.   Such statements and information are not false or misleading in any
          material respect as of the date(s) on which they are made or provided
          and do not omit any fact necessary in order to make such statements
          and information not false or misleading in any material respects as of
          such date(s).

     It is understood and agreed that such statements and information in the
     aggregate are, and in certain instances individually may be, material to
     the Company's decision to offer, provide, or so continue coverage of the
     related Loan; the Company issues the related Commitment and Certificate or
     continues coverage in reliance upon the accuracy and completeness of such
     statements and information and without any obligation to verify
     independently the statements and information submitted to it; and the
     Company's reliance upon the representations in Section 2.2(a) and (b) above
     survive the issuance of a Commitment and Certificate or such continuation
     of coverage.

     Without otherwise limiting the scope of this Section 2.2, a breach of
     Section 4.8 relating to down payment will be deemed a material
     misrepresentation for purposes of this Section 2.2. The down payment
     representation shall be effective whether or not it is made by the Insured
     or other Person with the intent to deceive or mislead, or with the
     knowledge that it is not true and correct.

2.3  CERTIFICATE CANCELLATION OR RESCISSION BY THE COMPANY FOR MISREPRESENTATION
     -Subject to Section 2.4, if any of the Insured's representations as
     described in Section 2.2 are materially false or misleading with respect to
     a Loan, the Company will have the right, at its option and to the extent
     permitted by applicable law, to cancel or rescind coverage under any
     Certificate retroactively to commencement of coverage (or if the
     misrepresentation occurs with respect to continuation of coverage upon
     assumption of a Loan, retroactively to the date of such continuation) and
     to return at that time all paid premiums retroactively to such applicable
     date.

2.4  INCONTESTABILITY FOR CERTAIN MISREPRESENTATIONS - Notwithstanding Sections
     2.2 and 2.3, no Claim for Loss will be denied or adjusted, nor will the
     Certificate's coverage be rescinded or canceled, by reason of any
     misrepresentations (whether by statements made or omitted) contained in an
     Application, provided that all of the following requirements, conditions,
     and circumstances, to the extent not waived in writing at the option of the
     Company, are satisfied:

     a.   The misrepresentation must not have been knowingly made, or knowingly
          participated in, by:

          1.   The Insured or any other Person which originated the Loan; or

          2.   Any other of the following Persons:

               i.   Correspondent lender, mortgage loan broker, or other
                    intermediary underwriting or processing the Loan on behalf
                    of the Insured or any other Person which originated the
                    Loan; or

MP-1103                                 6                                   8/94

<PAGE>

               ii.  Escrow or closing agents, or any other agent of, or broker
                    for, the Insured or any other Person which originated the
                    Loan acting with respect to the Loan or the related Property
                    transaction.

     b.   The Borrower must have made twelve (12) consecutive full installment
          payments of principal, interest, and impound or escrow amounts in the
          amounts as called for by the Loan, and all of those payments must have
          been made from the Borrower's own funds.

          A payment will be considered to be "consecutive" only if it is made
          prior to the date the next scheduled installment becomes due. The
          "Borrower's own funds" will include any funds used by the Borrower for
          the purpose of making installment payments, but will not include funds
          provided directly or indirectly by any Person (other than the
          Borrower) who is or was a party to the Loan or to the related Property
          transaction, unless expressly set forth in the Application.

     c.   This Section 2.4 will not apply to a Certificate if within twelve (12)
          months before or after a material misrepresentation by a Borrower or
          other Person (other than those Persons identified in Section 2.4(a)),
          there are one or more material misrepresentations in an Application
          (i) with respect to three or more other mortgage loans insured at any
          time by the Company for the Insured or any other lender and (ii) which
          result from the direct or indirect acts or omissions of the same
          Borrower or same other Person (including any other Person acting
          directly or indirectly in concert).

     d.   The Company's payment of a Claim will not limit any rights which the
          Company has against the Borrower or any other Person (other than the
          Insured) for any misrepresentation.

2.5  INITIAL PREMIUM - Within fifteen (15) days from the Certificate Effective
     Date, or such other date as the Company and the Insured may agree to in
     writing, the Insured must forward to the Company the appropriate initial
     premium. Tender of the initial premium will constitute a representation for
     purposes of Section 2.2 by the Insured that any special conditions included
     by the Company in the related Commitment have been satisfied and that no
     payment which is then due under the Loan is more than thirty (30) days past
     due. The Company will not rescind or cancel coverage, or deny or adjust a
     Claim for Loss, with respect to a Loan on the basis of a failure to satisfy
     a special condition (other than a special condition relating to completion
     of construction, rehabilitation, or repairs) if the Borrower has made
     twenty-four (24) consecutive full installment payments from the Borrower's
     own funds. The terms "installment payments," "consecutive," and "Borrower's
     own funds" shall have the meanings provided in Section 2.4(b).

2.6  RENEWAL OF CERTIFICATE AND TERMINATION FOR NONPAYMENT OF RENEWAL PREMIUM;
     REINSTATEMENT OF TERMINATED COVERAGE

     A.   TIMING; RESPONSIBILITY FOR PAYMENT - In order to continue coverage
          beyond the initial term, the Insured shall, at its option, pay renewal
          premiums to the Company for each Loan insured under this Policy,
          calculated at the rate specified in the related Certificate and in
          accordance with Section 2.6(c) below.

          The Company shall give thirty (30) days notice of the renewal due date
          to the Servicer, if a Servicer is shown on the records of the Company,
          and otherwise to the Owner, and renewal premiums shall be due and
          payable on or before the last day of the period covered by the
          previous premium payment.

MP-1103                                 7                                   8/94

<PAGE>

          If a Default occurs prior to the date through which the applicable
          premium has been paid, and if such Default is not cured and results in
          a Claim being filed, such Default shall remain covered and no further
          premium shall be due in order to maintain coverage of such Default.

          With respect to a Loan with renewal premiums due on an annual basis,
          if the annual renewal premium is not paid within a sixty (60) day
          grace period after the premium due date (but subject to the Owner's
          right to cure nonpayment as provided in Section 2.6(b)), the coverage
          of the Certificate and the Company's liability will terminate
          effective as of 12:01 a.m. on the first day following the date through
          which the applicable premium has been paid and as a result, any
          Default occurring after the date through which the applicable premium
          has been paid will not be covered.

          With respect to a Loan with renewal premiums due on a monthly basis,
          if the monthly renewal premium is not paid within such sixty (60) day
          grace period (but subject to the Owner's right to cure nonpayment as
          provided in Section 2.6(b)), the coverage of the Certificate and
          Company's liability will terminate at the end of such sixty (60) day
          grace period. However, if a Default on the Loan occurs during such
          sixty (60) day grace period, the Insured shall not be required to pay
          renewal premiums while such Default exists. If such Default is cured,
          all monthly renewal premiums not paid during the period of Default
          shall be payable within sixty (60) days after notice from the Company.
          If such Default is not cured and results in a Claim, the unpaid
          monthly renewal premiums through the renewal month in which such
          Default occurred shall be paid as provided in Section 6.3 by deduction
          from the Loss.

     B.   TRANSFER OR SEIZURE OF SERVICING - Notwithstanding paragraph (a)
          above, in the event that the Owner establishes to the reasonable
          satisfaction of the Company that the failure to pay renewal premiums
          on or before the renewal premium due date, or during the applicable
          grace period, was due to an error or omission that occurred in
          connection with the transfer, surrender, or seizure of servicing
          rights associated with a group of Loans, the Company shall permit the
          Owner or its new Servicer to reinstate coverage of the Loans contained
          in the group that are insured under this Policy provided that the
          following conditions are met:

          1.   The Owner or its new Servicer shall reinstate coverage with
               respect to all Loans insured under this Policy affected by such
               transfer, surrender, or seizure;

          2.   The renewal premiums are paid, in all events, on or before one
               hundred twenty (120) days after the applicable premium due date;
               and

          3.   Interest is paid on the renewal premiums due from the renewal
               premium due date until the date that such renewal premiums are
               paid at the three month Treasury Bill rate established at the
               first Treasury auction occurring during the month in which the
               renewal premium becomes due as published in the Wall Street
               Journal, or if not so published, in any other comparable
               publication.

     C.   CALCULATION - Renewal premiums due with respect to a Loan shall be
          payable in accordance with the method and at the rate specified on the
          related Certificate. Renewal premiums payable under the "outstanding
          unpaid principal balance" or "outstanding balance renewal" method
          shall be calculated by applying the applicable premium rate to the
          then unpaid principal balance of the Loan as of the date such premium
          is due and payable. Renewal premiums payable under the "level original
          insured principal balance" or "level renewal" method shall be
          calculated by applying the applicable premium rate to the original
          insured principal balance of the Loan.

<PAGE>

2.7  SPECIAL PROCEDURES FOR CERTIFICATES OF COVERAGE; PAYMENT OF INITIAL AND
     RENEWAL PREMIUMS

     a.   The Company may permit coverage of a Loan to be certified and become
          effective without the Insured's return of an executed Commitment or
          Certificate, but coverage will only become effective if, within
          fifteen (15) days after the Certificate Effective Date (or other date
          the Company and the Insured may agree to in writing), the Insured
          provides the Company with the Certificate Effective Date and other
          information required by the Company, and pays the required premium. If
          signature and return of an executed Commitment or Certificate is not
          required, the Insured will nevertheless be automatically deemed to
          have made all certifications, representations, and statements
          attributable to it in the form of the Commitment or Certificate, as
          though, and to the same extent as if, the Insured had executed and
          returned the Commitment or Certificate.

     b.   The Insured acknowledges that the Company deposits initial and renewal
          premium checks immediately upon receipt and agrees that the receipt
          and deposit of premium checks by the Company after the time specified
          in this Policy for receipt, does not constitute a waiver of the
          requirements of this Policy for timely receipt or an acceptance of
          premium by the Company. The Company will have the right to return such
          late premium payment, but only within sixty (60) days after receipt,
          in which case coverage will be canceled retroactively to the
          Certificate Effective Date for a late initial premium, or to the last
          day of the period covered by the previous premium payment for a late
          renewal premium. Receipt, deposit, and retention of a premium check
          will not constitute a waiver of any defenses with respect to any other
          matters which the Company may have under this Policy.

2.8  CANCELLATION BY THE INSURED OF A CERTIFICATE - The Insured may obtain
     cancellation of a Certificate by returning the Certificate to the Company
     or by making a written request to the Company for cancellation. Upon
     receipt, the Company will refund, where applicable, a portion of the
     premium paid in accordance with the appropriate cancellation schedule which
     is either attached to this Policy or which will be provided by the Company
     to the Insured upon request. However, no refund on a Certificate will be
     paid if the Loan is in Default at the time the Company receives the
     request. Cancellation of a Certificate will not cancel this Policy.

2.9  CANCELLATION OF POLICY - Either the Insured or the Company may cancel their
     respective right or obligation to receive or issue new Commitments or
     Certificates under this Policy by providing thirty (30) days written notice
     of cancellation of this Policy. However, Commitments and Certificates
     issued prior to such cancellation of this Policy will continue in force so
     long as all premiums are paid and all other terms and conditions of this
     Policy for coverage are complied with by the Insured.

2.10 RELATIONSHIP AMONG THE COMPANY, THE OWNER OF A LOAN, AND THE SERVICER OF A
     LOAN - The Company will be entitled to assume that the Insured identified
     on this Policy and under a Certificate is the Owner of the Loan. If the
     Company receives written notice acceptable to it that there is an Owner of
     the Loan who is not the Insured, the Company shall identify that Owner in
     its internal records and for purposes of this Policy. The Company shall be
     required to identify only one Owner for a Loan at any one time.

     The Company will provide the Owner of a Loan so identified in its records
     with an opportunity to cure nonpayments of renewal premium, as provided
     under Section 2.6(b); will notify such Owner of the Loan of a non-approved
     Servicer and allow replacement with a new Servicer, as provided under
     Section 4.5; will allow the Owner (or its designee, if any) to replace a
     Servicer and allow the replacement Servicer to become the Insured under
     Section 1.15; and will allow the Owner to

MP-1103                                 9                                   8/94

<PAGE>

     become the Insured under Section 1.15 if the Owner services the Loan
     itself. Any Person becoming an Insured under this Policy shall be subject
     to all of the terms and conditions of this Policy, to the same extent as
     any previous Insured hereunder and without regard to the extent of the
     knowledge or responsibility of such Person, relating to matters occurring
     before such Person became an Insured.

2.11 REFUND OF PREMIUM FOR DENIAL OF CLAIM IN FULL - If, because of a provision
     in Sections 3 or 4 (other than Sections 4.3, 4.6, or 4.7), no Loss is
     payable to the Insured, the Company shall return to the Insured all paid
     premiums retroactively and pro rata to the date when the event or
     circumstance occurred which resulted in no Loss being payable.

3.   CHANGES IN VARIOUS LOAN TERMS, SERVICING; COORDINATION AND DUPLICATION OF
     INSURANCE BENEFITS

3.1  LOAN MODIFICATIONS - Unless advance written approval is provided by, or
     obtained from, the Company, the Insured may not make any change in the
     terms of a Loan, including the borrowed amount, interest rate, term, or
     amortization schedule of the Loan, except as permitted by terms of the
     Loan; nor make any change in the Property; nor release the Borrower from
     liability on a Loan.

3.2  OPEN END PROVISIONS - The Insured may increase the principal balance of a
     Loan, provided that the written approval of the Company has been obtained.
     The Insured will pay the Company the additional premium due at the then
     prevailing premium rate.

3.3  ASSUMPTIONS - If a Loan is assumed with the Insured's approval, the
     Company's liability for coverage under its Certificate will terminate as of
     the date of such assumption, unless the Company approves the assumption in
     writing. The Company will not unreasonably withhold approval of an
     assumption. It is understood that coverage will continue, and that the
     restriction of this Section 3.3 will not apply, if under the Loan or
     applicable law, the Insured cannot exercise a "due-on-sale" clause or is
     obligated to consent to such assumption under the Loan or applicable law.
     Notwithstanding anything to the contrary in this Section 3.3, the Company
     will be deemed to have approved the assumption of any Loan where no release
     is requested and, under Section II-406.02 of the Federal National Mortgage
     Association's Servicing Guide or any successor provision approved by the
     Company thereof or any similar provision of the Federal Home Loan Mortgage
     Corporation's Sellers' & Servicers' Guide, the assumption is an "exempt
     transaction" that the Servicer is to approve without review of the terms of
     the transaction.

3.4  CHANGE OF SERVICING - If the servicing rights for a Loan are sold,
     assigned, or transferred by the Insured or the Owner, coverage of the Loan
     hereunder will continue, provided that written notice of the new Servicer
     is given to the Company and the new Servicer is approved in writing by the
     Company.

3.5  CHANGE OF OWNER - If a Loan or a participation in a Loan is sold, assigned,
     or transferred by its Owner, coverage of the Loan will continue, subject to
     all of the terms and conditions contained in this Policy. The new Owner of
     the Loan will be identified in the Company's records from the date that the
     Company receives written notice thereof. In the case of the sale of a
     participation in a Loan, the Company shall be notified of only one new
     Owner. If there is a new Owner, the Loan must continue to be serviced by a
     Person approved by the Company as a Servicer.

MP-1103                                10                                   8/94

<PAGE>

3.6  COORDINATION AND DUPLICATION OF INSURANCE BENEFITS - The Insured shall not
     carry duplicate mortgage guaranty insurance on any Loan, other than
     mortgage guaranty pool insurance or supplemental mortgage guaranty
     insurance, and if duplicate insurance is carried, coverage under this
     Policy shall be null and void.

4.   EXCLUSIONS FROM COVERAGE

     The Company will not be liable for, and this Policy will not apply to,
     extend to, or cover the following:

4.1  BALLOON PAYMENT - Any Claim arising out of or in connection with the
     failure of the Borrower to make any payment of principal and/or interest
     due under a Loan, (a) as a result of the Insured exercising its right to
     call the Loan (other than when the Loan is in Default) or because the term
     of the Loan is shorter than the amortization period, and (b) which is for
     an amount more than twice the regular periodic payments of principal and
     interest that are set forth in the Loan (commonly referred to as a "balloon
     payment"). This exclusion will not apply if the Insured, the Owner of the
     Loan, or other Person acting on either's behalf offers the Borrower, in
     writing, a renewal or extension of the Loan or a new loan which (i)
     constitutes a first lien, (ii) is at rates and terms generally prevailing
     in the marketplace (but otherwise subject to Section 3.1), (iii) is in an
     amount not less than the then outstanding principal balance, (iv) has no
     decrease in the amortization period, and (v) is offered regardless of
     whether the Borrower is then qualified under the Insured's or Owner's
     underwriting standards. This exclusion also will not apply if the Borrower
     is notified of the availability of such renewal or extension of the Loan or
     new loan and does not accept the renewal, extension, or new loan.

4.2  EFFECTIVE DATE - Any Claim resulting from a Default existing at the
     Certificate Effective Date or occurring after lapse or cancellation of a
     Certificate.

4.3  INCOMPLETE CONSTRUCTION - Any Claim when, as of the date of such Claim,
     construction of a Property is not completed in accordance with the
     construction plans and specifications.

4.4  FRAUD, MISREPRESENTATION, AND NEGLIGENCE - Any Claim not otherwise within
     the scope of Section 2.3 where there was fraud, misrepresentation, or
     negligence by the Insured with respect to the Loan, and the fraud,
     misrepresentation, or negligence (a) materially contributed to the Default
     resulting in such Claim; or (b) increased the Loss, except that if the
     Company can reasonably determine the amount of such increase, such Claim
     will not be excluded, but the Loss will be reduced to the extent of such
     amount.

4.5  NON-APPROVED SERVICER - Any Claim occurring when the Servicer, at time of
     Default or thereafter, is not approved in writing or in a list published by
     the Company; provided that this exclusion shall only apply if the Company
     notifies the Owner of the Loan in writing that a Servicer is no longer
     approved and if within ninety (90) days thereafter the Owner does not
     complete a transfer of servicing to a new Servicer approved by the Company.

4.6  PHYSICAL DAMAGE (OTHER THAN RELATING TO PRE-EXISTING ENVIRONMENTAL
     CONDITIONS) - Any Claim where, at any time after the Certificate Effective
     Date, Physical Damage occurs to a Property of a type other than as
     described in Section 4.7 and other than reasonable wear and tear, subject
     to the following provisions:

     a.   This exclusion will not apply if the Company in good faith determines
          that the aggregate cost of restoring all such Physical Damage is less
          than fifteen hundred dollars ($1,500), or such higher amount as the
          Company may provide from time to time.

MP-1103                                11                                   8/94

<PAGE>

     b.   The exclusion will apply only if: (i) the Company elects to acquire
          the related Property in settlement of a Claim and the damage occurred
          prior to expiration of the Settlement Period; or (ii) the damage
          occurred prior to the Default and such damage was the most important
          cause of the Default and the Property was either uninsured for loss
          arising from such Physical Damage or was insured for an amount which,
          net of any applicable deductibles, was insufficient to restore the
          Property as provided in paragraph (c) below.

     c.   The exclusion resulting from paragraph (b) will not apply if the
          Property is restored in a timely and diligent manner to its condition
          (except reasonable wear and tear) as of the Certificate Effective
          Date.

          In lieu of requiring restoration of the Property, as required by this
          subsection, the Company may, at its option, reduce the Claim Amount by
          an amount equal to the cost of such restoration.

     d.   For purposes of this Section 4.6, the Property subject to restoration
          will consist only of the land, improvements, or personal property
          deemed part of the real property under applicable law and chattel
          items affixed to the real property and identified in the appraisal of
          the Property at the time the Loan was made, whether or not they are
          deemed part of the real property.

     e.   Cost estimates relied upon by the Company in connection with this
          Section 4.6 shall be provided in writing by an independent party
          selected by the Company. The Company will furnish the Insured with any
          such written cost estimates, if requested by the Insured.

4.7  PRE-EXISTING ENVIRONMENTAL CONDITIONS - Any Claim where there is an
     Environmental Condition which existed on the Property (whether or not known
     by the Person submitting an Application for coverage of the Loan) as of the
     Certificate Effective Date, subject to the following provisions:

     a.   This exclusion will not apply if the existence of such Environmental
          Condition, or the suspected existence of such Environmental Condition,
          was specifically disclosed to the Company in the Application relating
          to the Property.

     b.   This exclusion will apply only if such Environmental Condition (i) was
          a principal cause of the Default, and (ii) has made the principal
          Residential structure on the Property uninhabitable. A structure will
          be considered "uninhabitable" if generally recognized standards for
          Residential occupancy are violated or if, in the absence of such
          standards, a fully informed and reasonable person would conclude that
          such structure was not safe to live in without fear of injury to
          health or safety.

     c.   This exclusion will not apply if the Environmental Condition is
          removed or remedied in a timely and diligent manner in accordance with
          applicable governmental standards for safe Residential occupancy.

4.8  DOWN PAYMENT - Any Claim involving a Loan which is for the purchase of the
     Property, and for which the Borrower did not make a down payment as
     described in the Application.

4.9  FIRST LIEN STATUS - Any Claim, if the mortgage, deed of trust, or other
     similar instrument executed by the Borrower and Insured hereunder did not
     provide the Insured at origination with a first lien on the Property.

MP-1103                                12                                   8/94

<PAGE>

4.10 BREACH OF INSURED'S OBLIGATIONS OR FAILURE TO COMPLY WITH TERMS - Any Claim
     involving or arising out of any breach by the Insured of its obligations
     under, or its failure to comply with the terms of, this Policy or of its
     obligations as imposed by operation of law, if the breach or failure:

     a.   Materially contributed to the Default resulting in such Claim; or

     b.   Increased the Loss, except that if the Company can reasonably
          determine the amount of such increase, such Claim will not be
          excluded, but the related Loss will be reduced to the extent of such
          amount.

4.11 RELEASE OF BORROWER; DEFENSES OF BORROWER - The Insured's execution of a
     release or waiver of the right to collect any portion of the unpaid
     principal balance of a Loan or other amounts due under the Loan will
     release the Company from its obligation under its Certificate to the extent
     and amount of said release. If, under applicable law, the Borrower
     successfully asserts defenses which have the effect of releasing, in whole
     or in part, the Borrower's obligation to repay the Loan, or if for any
     other reason the Borrower is released from such obligation, the Company
     will be released to the same extent and amount from its liability under
     this Policy, except as provided by Section 7.5.

5.   CONDITIONS PRECEDENT TO PAYMENT OF CLAIM

     It is a condition precedent to the Company's obligation to pay a Loss that
     the Insured comply with all of the following requirements:

5.1  NOTICE OF DEFAULT - The Insured must give the Company written notice:

     a.   Within forty-five (45) days of the Default, if it occurs when the
          first payment is due under the Loan; or

     b.   Within ten (10) days of either:

          1.   The date when the Borrower becomes four (4) months in Default on
               the Loan; or

          2.   The date when any Appropriate Proceedings which affect the Loan
               or the Property or the Insured's or Borrower's interest therein
               have been started;

          whichever occurs first.

5.2  MONTHLY REPORTS - Following a notice of Default on the Loan, the Insured
     must give the Company monthly reports on forms or in a format furnished or
     approved by the Company on the status of the Loan and on the servicing
     efforts undertaken to remedy the Default. These monthly reports may be
     furnished less frequently if allowed in writing by the Company and must
     continue until the Borrower is no longer in Default, the Appropriate
     Proceedings terminate, or until the Insured has acquired the Property.

5.3  COMPANY'S OPTION TO ACCELERATE FILING OF A CLAIM - If the Company so
     directs, at any time after receiving the Insured's Notice of Default, the
     Insured must file a Claim within twenty (20) days after notice from the
     Company. The Company will then make a payment of Loss in accordance with
     the percentage guaranty option in Section 6.3(b). Thereafter, following the
     acquisition of Borrower's Title by the Insured, the Insured will be
     entitled to file a supplemental Claim at the time prescribed in Section 6.1
     in an amount equal to the sum of its advances, less the deductions, all as

MP-1103                                13                                   8/94

<PAGE>

     specified in Section 6.2, to the extent not included in the payment of the
     initial Claim. Such supplemental Claim must be paid by the Company in
     accordance with Section 6.3(b). If the Company exercises its option under
     this Section 5.3, the Company shall not have the right to direct or
     participate in a deficiency recovery under Section 7.2.

5.4  VOLUNTARY CONVEYANCE - The Insured may only accept a conveyance of the
     Property from the Borrower in lieu of foreclosure or other proceedings if
     the prior written approval of the Company has been obtained.

5.5  APPROPRIATE PROCEEDINGS - The Insured must begin Appropriate Proceedings no
     later than when the Loan becomes six (6) months in Default unless the
     Company provides written instructions that some other action be taken. Such
     instructions may be general or applicable only to specific Loans. The
     Company reserves the right to direct the Insured to institute Appropriate
     Proceedings at any time after Default. When either defending against or
     bringing Appropriate Proceedings, the Insured must report its status to the
     Company as reasonably and expeditiously as possible.

     In conducting Appropriate Proceedings, the Insured must:

     a.   Diligently pursue the Appropriate Proceedings once they have begun;

     b.   Apply for the appointment of a receiver and assignment of rents, if
          permitted by law and requested by the Company;

     c.   Furnish the Company with copies of all notices and pleadings filed or
          required in the Appropriate Proceedings, except as the Company may
          waive such requirements in writing;

     d.   Act and bid at the foreclosure sale in accordance with Section 5.11 so
          that its ability to preserve, transfer, and assign to the Company its
          rights against the Borrower are not impaired, and so that the rights
          of the Company under this Policy against the Borrower are fully
          protected. Such rights include any rights to obtain a deficiency
          judgment, subject to the Company's compliance with Sections 7.2 and
          7.3 relating to establishing a deficiency; and

     e.   When requested by the Company, furnish the Company with a written
          statement indicating the estimated potential Claim Amount (as computed
          under Section 6.2) at least fifteen (15) days before the foreclosure
          sale.

5.6  MITIGATION OF LOSS - The Insured shall, or shall cause its Servicer to,
     actively cooperate with the Company to prevent and mitigate the Loss and to
     assist the Company in the Company's attempts to prevent and mitigate the
     Loss, including but not limited to, taking reasonable and good faith
     efforts to cure the Default and, if such attempts are unsuccessful, to
     effectuate the early disposition of the Property.

     The Insured shall report to the Company any pre-foreclosure sale offers
     received by the Borrower and known to the Insured. If a pre-foreclosure
     sale is approved by both the Insured and the Company, but the sale does not
     close for any reason, the Company shall continue to administer the Policy
     as if no sale had been attempted.

     The Company agrees to administer the Policy in good faith.

MP-1103                                14                                   8/94

<PAGE>

5.7  ADVANCES - The Insured shall advance:

     a.   Normal and customary hazard insurance premiums (in calculating the
          Claim Amount pursuant to Section 6.2, such premiums shall be prorated
          to the date that the Claim is paid);

     b.   Real estate property taxes that become due and payable on or after the
          date of Default (but not including penalties or late fees);

     c.   The costs of engaging in foreclosure and eviction proceedings
          (including court costs and moving costs where required by law to be
          paid by the evicting party), reasonable or customary attorney's fees
          not exceeding three percent (3%) of the sum of the outstanding
          principal balance and accumulated interest due under the Loan; and

     d.   Reasonable expenses necessary for the protection and preservation of
          the Property as approved by the Company. Although advance approval is
          not required, the Company reserves the right to disallow advances
          reflecting such expenses upon payment of the Claim if, in the
          Company's reasonable judgment, such advances were not reasonable or
          necessary. Insureds are therefore encouraged to seek the Company's
          prior consent.

5.8  CLAIM INFORMATION AND OTHER REQUIREMENTS - The Insured must provide the
     Company with:

     a.   All information reasonably requested by the Company;

     b.   A completed form furnished by or acceptable to the Company for payment
          of a Claim;

     c.   If the Property is not being acquired by the Company: a copy of an
          executed trustee's or sheriff's deed (which may be unrecorded)
          conveying Borrower's Title to this Property to the Insured (or
          satisfactory evidence that the foreclosure sale has been completed if
          the Borrower's right of redemption has not expired); or a deed from
          the Borrower (which may be unrecorded) if a voluntary conveyance has
          been approved by the Company, conveying to the Insured the title that
          was required by the Company in the approval of the conveyance.

          In the event the most important cause of Default was a circumstance or
          event which would prevent the Insured from obtaining Good and
          Merchantable Title, the Insured shall instead provide the Company with
          evidence described in Section 5.8(d)(2) that it has acquired Good and
          Merchantable Title to the Property;

     d.   If the Property is being acquired by the Company:

          1.   A recordable deed in normal and customary form containing the
               customary warranties and covenants conveying to the Company or
               its designee Good and Merchantable Title to the Property;

          2.   A title insurance policy acceptable to the Company or an
               attorney's opinion of title acceptable to the Company, confirming
               that the Insured has and can convey to the Company Good and
               Merchantable Title to the Property;

          3.   Possession of the Property, but only if the Company has required
               such Possession in writing; and

     e.   Access to the Property, if requested by the Company pursuant to
          Section 6.4(b).

MP-1103                                15                                   8/94

<PAGE>

5.9  ACQUISITION OF BORROWER'S TITLE NOT REQUIRED - The Insured will not be
     required to acquire Borrower's Title to a Property if (a) the Company
     approves a sale of the Property prior to a foreclosure sale and such sale
     is closed; (b) the Company requires an early Claim filing pursuant to
     section 5.3, except that such acquisition will be required as a condition
     to the Insured's filing of a supplemental Claim; or (c) the Property is
     acquired by someone other than the Insured at a foreclosure sale, as
     provided in Section 5.11, or thereafter pursuant to exercise of rights of
     redemption.

5.10 SALE OF A PROPERTY BY THE INSURED BEFORE END OF SETTLEMENT PERIOD

     a.   The Insured must submit to the Company any offer to purchase a
          Property which would mitigate the Company's Loss and which it receives
          after the Company has notified the Insured that it will acquire the
          Property and before the end of the Settlement Period. The Company must
          then promptly notify the Insured that it will either (i) not approve
          of such offer, in which case the Company's notice to acquire the
          Property will remain in effect, or (ii) approve such offer, in which
          case the Company's notice of acquisition will remain in effect, if the
          approved offer does not close as scheduled. The Insured shall promptly
          notify the Company if the approved offer does not close as scheduled.

     b.   If the Company has not notified the Insured that it will acquire the
          Property, and if the Company's right to acquire the Property has not
          expired pursuant to Section 6.5 or has not been waived, the Insured
          must submit to the Company for approval any offer to purchase the
          Property which would be acceptable to the Insured and which would
          mitigate the Company's Loss. The Company shall then promptly either
          approve or not approve such offer. If an approved sale does not close,
          the Company may settle under either of the settlement options set
          forth in Section 6.3, provided that if the Settlement Period has
          expired, (i) interest as provided for in Section 6.5 shall be payable,
          and (ii) if the Company wishes to settle under Section 6.3(a), the
          Insured's obligations in connection with the transfer of the Property
          to the Company shall be as required by this Policy subject to the
          limitation that they shall not be more burdensome to the Insured than
          its obligations (including, but not limited to, its obligations as to
          the condition of the Property) as seller in the approved sale that
          failed to close.

     c.   The following provisions shall apply to offers submitted to the
          Company under this Section 5.10:

          1.   The Insured shall provide the Company with a good faith estimate
               of gross proceeds and expenses in sufficient detail for the
               Company to calculate the estimated net proceeds described below.
               The Company may not require any changes to the offer or direct
               the marketing of the Property or expenditures by the Insured for
               restoration of the Property as a condition to its approval.

          2.   If the Company approves the offer submitted by the Insured, it
               must also advise the Insured of the estimated net proceeds which
               it has calculated. The estimated net proceeds calculated by the
               Company will be the estimated gross sales proceeds to be received
               by the Insured less all reasonable estimated expenses submitted
               by the Insured and approved by the Company in its approval of the
               offer which have been or are expected to be paid by the Insured
               in obtaining and closing the sale of the Property. If the
               estimated net proceeds as calculated by the Company is acceptable
               to the Insured, the Loss payable shall be computed as determined
               in Section 5.10(c)(3) below. If such estimated net proceeds is
               not acceptable to the Insured, the offer shall be deemed to have
               not been approved by the Company.

MP-1103                                16                                   8/94

<PAGE>

          3.   If the Company approves the offer, the Loss payable by the
               Company under this Section 5.10 will be the lesser of (i) the
               actual net amount as calculated below, or (ii) the percentage
               guaranty option under Section 6.3(b) calculated without regard to
               a sale of the Property. The actual net amount will be the Claim
               Amount calculated under Section 6.2, except that (a) delinquent
               interest will be computed through the closing date for sale of
               the Property and (b) the Claim Amount shall be reduced by the
               actual net proceeds realized by the Insured from sale of the
               Property. The actual net proceeds will be determined in the same
               manner as the estimated net proceeds, but on the basis of the
               actual sales proceeds and actual expenses, such expenses not to
               exceed the amounts approved by the Company either at the time the
               Company approved the offer or thereafter.

          4.   The Company shall not unreasonably withhold its approval of
               expenses submitted to it after its approval of an offer. Expenses
               paid to Persons employed or controlled by the Insured or the
               Owner of the Loan or their internal costs will not be allowed in
               calculation of either the estimated or actual net proceeds.

          5.   If requested by the Company, the Insured or the Owner shall
               advise the Company of the name of the real estate broker or other
               Person marketing the Property for the Insured or the Owner and
               authorize such broker or other Person to release marketing
               information about the Property to the Company.

5.11 FORECLOSURE BIDDING INSTRUCTIONS - Bid an amount at the foreclosure sale
     which is not less than the minimum amount nor more than the maximum amount
     set forth below, unless the Company notifies the Insured of other
     instructions or waives its right to give bidding instructions, in writing.

     a.   If the Fair Market Value of a Property is less than the Uninsured Loan
          Balance, the Insured shall start bidding at not less than the Fair
          Market Value of the Property and may continue bidding up to a maximum
          of the Uninsured Loan Balance.

     b.   If the Fair Market Value of a Property is greater than the Uninsured
          Loan Balance, the Insured shall start bidding at not less than the
          Uninsured Loan Balance up to a maximum amount equal to the Claim
          Amount.

     If other bidding instructions are provided, those instructions will not
     specify a maximum bid that is less than the Uninsured Loan Balance, and, if
     the Property is subject to redemption for less than the outstanding amount
     of the Loan, then such other bidding instructions will not specify an
     opening bid of less than the Uninsured Loan Balance.

     The Insured is not required to acquire Borrower's Title if it has bid in
     accordance with paragraphs (a) and (b), whether or not pursuant to
     directions from the Company.

5.12 EFFECT OF UNEXPIRED REDEMPTION PERIOD ON PAYMENT OF A CLAIM - If the
     Insured files a Claim prior to expiration of an applicable redemption
     period, the Loss payable shall only be computed through the date of filing
     of the Claim, and if the Company elects to acquire the Property, the
     Insured will remain responsible for management and control of the Property
     until the Company's acquisition thereof, which may be after expiration of
     the redemption period, but not later than as required by Section 6.4.

MP-1103                                17                                   8/94

<PAGE>

6.   LOSS PAYMENT PROCEDURE

6.1  FILING OF CLAIM - The Insured shall file a Claim after, but no later than
     sixty (60) days following, the conveyance to the Insured of Borrower's
     Title to the Property. If the Insured is not required to have Borrower's
     Title to file a Claim for a reason described in Section 5.9, then the Claim
     must be filed (a) within sixty (60) days after the Property is conveyed in
     a pre-foreclosure sale, at the foreclosure sale, or by exercise of the
     rights of redemption, or (b) at the time specified by Section 5.3. If the
     Insured fails to file a Claim within the applicable time, the Insured will
     not be entitled to, and the Company will not be obligated for, any payment
     under this Policy for amounts, including additional interest and expenses,
     which would otherwise be claimable, but which accrue or are incurred after
     the sixty (60) day period for filing of a Claim.

     If the Insured fails to file a Perfected Claim within one hundred eighty
     (180) days after the filing of the Claim (or within such longer period of
     time as the Company may allow in writing), the Insured will no longer be
     entitled to payment of a Loss and the Company will not be obligated to make
     any payment under this Policy.

6.2  CALCULATION OF CLAIM AMOUNT - Subject to Section 7.5, the Claim Amount will
     be an amount equal to the sum of:

     a.   The amount of unpaid principal balance due under the Loan as of the
          date of Default without capitalization of delinquent interest,
          penalties, or advances;

     b.   The amount of accrued and unpaid interest due on the Loan computed at
          the contract rate stated in the Loan through the date that the Claim
          is filed with the Company, but excluding applicable late charges,
          penalty interest, or other changes to the interest rate by reason of
          Default; and

     c.   The amount of advances incurred by the Insured under Section 5.7 prior
          to filing of the Claim (except to Persons employed or controlled by
          the Insured or the Owner of the Loan or their other internal costs)
          provided that:

          1.   Attorney's fees advanced for completion of Appropriate
               Proceedings and obtaining Possession of the Property will not be
               allowed to the extent they exceed three percent (3%) of the sum
               of the unpaid principal balance plus the accrued and accumulated
               interest due; and

          2.   Such advances, other than attorney's fees, must have first become
               due and payable after the Default, and payment of such advances
               must be pro-rated through the date the Claim is filed with the
               Company;

     less:

     i.   The amount of all rents and other payments (excluding proceeds of a
          sale of the Property and the proceeds of fire and extended coverage
          insurance) collected or received by the Insured, which are derived
          from or in any way related to the Property;

     ii.  The amount of cash remaining in any escrow account as of the last
          payment date;

     iii. The amount of cash to which the Insured has retained the right of
          possession as security for the Loan;

MP-1103                                18                                   8/94

<PAGE>

     iv.  The amounts paid under applicable fire and extended coverage policies
          which are in excess of the cost of restoring and repairing the
          Property, if the Property is damaged, and which have not been paid to
          the Borrower or applied to the payment of the Loan as required by the
          terms of the Loan; and

     v.   Any other amounts claimed by the Insured to the extent they are
          excluded by reason of Section 4.10.

6.3  PAYMENT OF LOSS; COMPANY'S OPTIONS - Within the Settlement Period, but only
     if the Insured has satisfied all requirements for a payment of Loss and if
     the Company has received a Perfected Claim, the Company shall at its sole
     option exercise its:

     a.   Property acquisition settlement option. Pay to the Insured as the Loss
          the Claim Amount calculated in accordance with Section 6.2 for the
          Company's acquisition of the Property; or

     b.   Percentage guaranty option. Allow the Insured to retain all rights in
          and title to the Property, and pay to the Insured as the Loss the
          Claim Amount calculated in accordance with Section 6.2 of this Policy
          multiplied by the percentage of coverage or as otherwise calculated as
          specified in the Certificate; or

     c.   Pre-Claim sale option. If the terms and conditions of Section 5.10 are
          met, pay to the Insured as the Loss the amount calculated in
          accordance with Section 5.10; and if the terms and conditions of
          Sections 5.9(c) and 5.11 are met, then the Company will pay the lesser
          of (i) the percentage guaranty option amount and (ii) the Claim Amount
          less the amount realized by the Insured at the foreclosure sale or
          from the redemption of the Property as required by law.

     In addition to the sum due pursuant to the option described above which the
     Company selects, the Loss payable by the Company will include the other
     amounts provided for under Sections 5.3, 6.5, or 7.2 when such Sections are
     applicable. The Company will deduct from its payment of Loss the aggregate
     amounts of any payments of Loss which it had previously made. In the event
     of a Loss on a Loan with renewal premiums due monthly, which results from a
     Default covered under Section 2.6(a), the Company shall deduct from the
     payment of Loss an amount equal to any unpaid renewal premiums for the
     subject Loan through the end of the monthly renewal period in which such
     Default occurred.

6.4  CALCULATION OF SETTLEMENT PERIOD - The Settlement Period will be a sixty
     (60) day period after the Company's receipt of a Claim, calculated as
     follows:

     a.   No later than the twentieth (20) day after the filing of a Claim, the
          Company may notify the Insured of additional documents or information
          which it requires for processing the Claim. The sixty (60) day period
          will be suspended until the Company receives such additional documents
          and information. The Company may request additional documents and
          information after such twenty (20) day period, and the Insured must
          use reasonable efforts to satisfy such request.

     b.   No later than the twentieth (20) day after filing of a Claim, the
          Company may notify the Insured that it will require access to the
          Property sufficient to inspect, appraise, and evaluate the Property.
          If the Company does not notify the Insured by that date, its right to
          such access will be deemed waived. If such notice is given, the
          Insured will use its best efforts to provide access to the Company
          and, if access is not then available, the sixty (60) day period will
          be suspended from the date such notice was given until the Company
          receives notice from the Insured that access is available to it. If
          access is in fact

MP-1103                                19                                   8/94

<PAGE>

          not available when sought by the Company after such notice from the
          Insured, the Company will promptly notify the Insured of such
          unavailability, and the passage of the sixty (60) day period will
          remain suspended as if the Insured's notice of availability had not
          been given to the Company.

     c.   If the Company has elected to acquire the Property in settlement of a
          Claim, the sixty (60) day period also will be suspended, if necessary,
          for there to be a period of ten (10) days after the date on which the
          Insured satisfies all conditions to acquisition, including any
          required restoration of the Property, the Insured's delivery of a
          recordable deed and title policy or opinion evidencing Good and
          Merchantable Title (not subject to any rights of redemption, unless
          the Company waives such requirement) and, if applicable, delivery of
          Possession of the Property.

     d.   If the sixty (60) day period is suspended for more than one reason,
          the resulting suspended periods will only be cumulative if in fact
          they occur at different times; to the extent they occur
          simultaneously, they will not be cumulative.

6.5  PAYMENT BY THE COMPANY AFTER THE SETTLEMENT PERIOD - If the Company has not
     paid a Loss during the Settlement Period, then (a) the Company will include
     in its payment of Loss, if a Loss is ultimately payable, simple interest on
     the amount payable accruing after the Settlement Period to the date of
     payment of Loss at the applicable interest rate or rates which would have
     been payable on the Loan during such period, and (b) the Company will no
     longer be entitled to acquire the Property as an option for payment of the
     Loss. The Company must either pay the amount of applicable Loss (including
     any additional applicable interest as computed above) or deny the Claim in
     its entirety within (a) one hundred twenty (120) days after expiration of
     the Settlement Period, or (b) if the Settlement Period has not expired, no
     later than one hundred eighty (180) days after filing of the Claim. If at a
     later date it is finally determined by agreement between the Insured and
     the Company (or by completion of legal or other proceedings to which the
     Insured and the Company are parties) that the Company was not entitled to
     deny all or a portion of the Claim, the Company will include in any
     resulting subsequent payment of Loss interest as calculated above through
     the date of such payment on the amount of Loss which the Company was not
     entitled to deny.

6.6  DISCHARGE OF OBLIGATION - payment by the Company of the full amount of Loss
     required to be paid in accordance with this Policy will be a full and final
     discharge of its obligation with respect to such Loss under this Policy.

7.   ADDITIONAL CONDITIONS

7.1  PROCEEDINGS OF EMINENT DOMAIN - In the event that part or all of a Property
     is taken by eminent domain, condemnation, or by any other proceedings by
     federal, state or local governmental unit or agency, the Insured must
     require that the Borrower apply the maximum permissible amount of any
     compensation awarded in such proceedings to reduce the principal balance of
     the Loan, in accordance with the law of the jurisdiction where the Property
     is located.

7.2  PURSUIT OF DEFICIENCIES

     a.   To facilitate the independent decisions of both the Insured and the
          Company of whether to pursue or establish a deficiency against a
          Borrower, the Insured shall provide the Company with any information
          it may have relevant to collecting on a deficiency judgment for that
          case. The Company will discuss all such information it may have with
          the Insured so that the parties can decide whether any Appropriate
          Proceedings necessary to establishing or

MP-1103                                20                                   8/94

<PAGE>

          pursuing a deficiency are to be pursued for the benefit of both
          parties or whether one of the parties will elect not to participate in
          any recovery.

          The Insured will be entitled to pursue Appropriate Proceedings, or
          shall, at the direction of the Company, pursue Appropriate Proceedings
          through the end of the Settlement Period, which may result in the
          Borrower becoming liable for a deficiency after completion of the
          Insured's acquisition of a Property. Such pursuit may not be directed
          by the Company unless the Company notifies the Insured at least thirty
          (30) days before the foreclosure sale that it will pursue a deficiency
          judgment, in whole or in part for its account. If the Company does not
          so notify the Insured, the deficiency judgment, if established by the
          Insured, will be solely for the account of the Insured, and the
          Company will not be subrogated to any rights to pursue the deficiency
          judgment.

          The Insured will be deemed to be participating in Appropriate
          Proceedings solely at the request of the Company when such proceedings
          are not a condition precedent to obtaining Borrower's Title to or
          Possession of a Property and, after the parties have exchanged
          information on the Loan, the Insured has advised the Company in
          writing that the Insured does not wish to participate in such
          proceedings.

     b.   Notwithstanding the provisions of Section 6 (Loss Payment Procedure)
          above, in the case where a deficiency against the Borrower is being
          pursued solely at the request of the Company, then any Deficiency
          Expenses shall be added to the amount of the Loss. If a deficiency
          against a Borrower is being pursued as part of Appropriate Proceedings
          for the benefit of both the Insured and the Company, then at the time
          such deficiency rights are established or a deficiency judgment is
          obtained, whichever shall occur first, the Deficiency Expenses plus
          any similar expenses incurred by the Company in connection with such
          deficiency shall be settled between the parties on the same pro rata
          basis set forth in Section 7.3 (Subrogation) for the settlement of
          deficiency recoveries. Expenses and costs arising after that point
          shall be treated as collection expenses to be netted against the
          deficiency recovery, if any (and, if none, to be shared between the
          parties on the same pro rata basis when it becomes clear that nothing
          will be recovered).

7.3  SUBROGATION - Subject to Section 7.2(a), and only to the extent that the
     Company is entitled under applicable law to pursue such deficiency rights,
     the Company shall be subrogated pro rata, to the full extent permitted by
     law, to all of the Insured's Recovery Rights with respect to a Loan, upon
     payment of a Claim hereunder. The Company's pro rata share of the net
     deficiency recovered (i.e., amounts recovered less reasonable costs and
     expenses) with respect to any Loan shall be the amount of the Loss divided
     by the amount of the deficiency judgment. Internal staff costs and overhead
     expenses shall not be deducted in determining the amount of a net
     deficiency recovery unless specifically agreed to in writing by the
     parties. The Insured hereby designates the Company as its exclusive agent
     (a) to pursue all of the Insured's Recovery Rights to which the Company has
     not become subrogated by payment of a Claim (i.e., the Insured's share of
     the Recovery Rights), (b) to file any action in the Company's name as
     assignee of the Insured, to collect on the Insured's Recovery Rights, and
     (c) to settle and compromise any such Recovery Rights on behalf of the
     Insured, it being understood and agreed that the Company shall have the
     exclusive rights to pursue and settle all Recovery Rights for any Loan on
     which a Claim payment is made hereunder, unless waived in writing by the
     Company. If the Company decides not to pursue Recovery Rights with respect
     to a Loan, then the Company shall issue a written waiver of its subrogation
     and management rights to the Insured. The Insured shall execute and deliver
     at the request of the Company such instruments and documents, and undertake
     such actions as may be necessary to transfer, assign, and secure such
     Recovery Rights to the Company. The Insured shall refrain from any action,
     either before or after payment of a Claim hereunder, that shall prejudice
     such Recovery Rights.

MP-1103                                21                                   8/94

<PAGE>

     Notwithstanding any provision in the foregoing paragraph to the contrary,
     in the event the Insured has, in addition to Recovery Rights against a
     Borrower or any other Person, a claim or claims against such Borrower or
     other Person not related to the Recovery Rights, then the Insured shall
     have the right to pursue in its own name all the Recovery Rights in
     conjunction with the Insured's other claim or claims, and the Company will
     waive its right to manage the pursuit of the Recovery Rights (but not the
     Company's pro rata subrogation rights).

7.4  POLICY FOR EXCLUSIVE BENEFIT OF THE INSURED AND THE OWNER - A Commitment
     and Certificate issued as the result of any Application submitted hereunder
     and the coverage provided under this Policy will be for the sole and
     exclusive benefit of the Insured and the Owner of the related Loan, and in
     no event will any Borrower or other Person be deemed a party to, or an
     intended beneficiary of, this Policy or any Commitment or Certificate.

7.5  EFFECT OF BORROWER INSOLVENCY OR BANKRUPTCY ON PRINCIPAL BALANCE - If under
     applicable insolvency or bankruptcy law, a Loan's principal balance secured
     by a Property is reduced (after all appeals of such reduction are final or
     the time for such appeals has lapsed without appeal), the portion of such
     principal balance of the Loan not secured by the Property, and related
     interest, will be includable in the Claim Amount, as provided in this
     Section 7.5.

     If a Default occurs on the Loan, the Insured has acquired Borrower's Title
     or Good and Merchantable Title to the Property if required by this Policy,
     and all other requirements for filing of a Claim are complied with, the
     Insured will be entitled to include in the Claim Amount (a) the amount of
     the principal balance of the Loan which was deemed unsecured under
     applicable insolvency or bankruptcy law, less any collections or payments
     on such unsecured principal balance received by the Insured, and (b)
     interest thereon at the rate and as computed in Section 6.2, from the date
     of Default giving rise to the Claim (but for no prior period). In no event
     will any expenses or other amounts associated with the amount by which the
     principal balance of the Loan became unsecured be includable in the Claim
     Amount, directly or by an addition to the principal balance includable in
     the Claim Amount.

7.6  ARBITRATION OF DISPUTES; SUITS AND ACTIONS BROUGHT BY THE INSURED

     a.   Unless prohibited by applicable law, the Insured, at its option, may
          elect to settle by arbitration a controversy, dispute, or other
          assertion of liability or rights which it initiates arising out of or
          relating to this Policy, including the breach, interpretation, or
          construction thereof. Such arbitration shall be conducted in
          accordance with the Title Insurance Arbitration Rules of the American
          Arbitration Association in effect on the date the demand for
          arbitration is made, or if such Rules are not then in effect, such
          other Rules of the American Arbitration Association as the Company may
          designate as its replacement.

          The arbitrator(s) shall be neutral person(s) selected from the
          American Arbitration Association's National Panel of Arbitrators
          familiar with the mortgage lending or mortgage guaranty insurance
          business. Any proposed arbitrator may be disqualified during the
          selection process, at the option of either party, if such individual
          is, or during the previous two years has been, an employee, officer,
          or director of any mortgage guaranty insurer, or of any entity engaged
          in the origination, purchase, sale, or servicing of mortgage loans or
          mortgage-backed securities.

     b.   No suit or action (including arbitration hereunder) brought by the
          Insured against the Company with respect to the Company's liability
          for a Claim under this Policy shall be sustained in any court of law
          or equity or by arbitration unless the Insured has substantially
          complied with the terms and conditions of this Policy, and unless the

MP-1103                                22                                   8/94

<PAGE>

          suit or action is commenced within three (3) years (five (5) years in
          Florida or Kansas) after the Insured has acquired Borrower's Title to
          the Property or sale of the Property approved by the Company is
          completed, whichever is applicable to a Loan. No such suit or action
          with respect to a Claim may be brought by the Insured against the
          Company until sixty (60) days after such acquisition of Borrower's
          Title or sale, as applicable to a Loan.

     c.   If a dispute arises concerning the Loan which involves either the
          Property or the Insured, the Company has the right to protect its
          interest by defending the suit, even if the allegations contained in
          such suit are groundless, false, or fraudulent. The Company is not
          required to defend any lawsuit involving the Insured, the Property, or
          the Loan.

7.7  AMENDMENTS; NO WAIVER; RIGHTS AND REMEDIES; USE OF TERM "INCLUDING"

     a.   The Company reserves the right to amend the terms and conditions of
          this Policy from time to time; provided, however, that any such
          amendment will be effective only after the Company has given the
          Insured written notice thereof by endorsement setting forth the
          amendment. Such amendment will only be applicable to those
          Certificates where the related Commitment was issued on or after the
          effective date of the amendment.

     b.   No condition or requirement of this Policy will be deemed waived,
          modified, or otherwise compromised unless that waiver, modification,
          or compromise is stated in writing properly executed on behalf of the
          Company. Each of the conditions and requirements of this Policy is
          severable, and a waiver, modification, or compromise of one will not
          be construed as a waiver, modification, or compromise of any other.

     c.   No right or remedy of the Company provided for by this Policy will be
          exclusive of, or limit, any other rights or remedies set forth in this
          Policy or otherwise available to the Company by law or equity.

     d.   As used in this Policy, the term "include" or "including" will mean
          "include or including, without limitation."

7.8  NO AGENCY - Neither the Insured, any Servicer, or Owner, nor any of their
     employees or agents, will be deemed for any reason to be agents of the
     Company. Neither the Company, nor any of its employees or agents, will be
     deemed for any reason to be agents of any Insured, Servicer, or Owner.

7.9  SUCCESSORS AND ASSIGNS - This Policy will inure to the benefit of and shall
     be binding upon the Company and the Insured and their respective successors
     and permitted assigns.

7.10 APPLICABLE LAW AND CONFORMITY TO LAW - All matters under this Policy will
     be governed by and construed in accordance with the laws of the
     jurisdiction in which the office of the original Insured on a Certificate
     is located. Any provision of this Policy which is in conflict with any
     provision of the law of such jurisdiction is hereby amended to conform to
     the provisions required by that law.

7.11 NOTICE - Premium payments are to be paid as provided in Section 2 and sent
     to the Company at the address listed on the Commitment, or as otherwise
     instructed by the Company in writing. All other notices, Claims, tenders,

As used above, the following terms have the indicated meanings:

"Negotiable Debt Obligation" means a debt obligation in a stated principal
amount with a non-variable fixed maturity, which cannot be redeemed by its
issuer before its maturity nor put to the issuer for redemption before its
maturity. It must bear interest on its stated principal amount at a non-variable
fixed rate until maturity (or, in the case of an obligation with an original
maturity of less than one year, bear no interest at all).

(iii) Other Eligible Support. The following items will qualify as "Other
Eligible Support" for the party specified: Not Applicable.

(iv) Thresholds.

(A) "Independent Amount" means with respect to Party A: Not Applicable.

"Independent Amount" means with respect to Party B: Not Applicable.

(B) "Threshold" means with respect to Party A, infinity, provided that for so
long as (1) a First Rating Trigger Event with respect to Moody's has occurred
and is continuing and either (i) such First Rating Trigger Event existed at the
time this Annex was executed or (ii) at least 30 Local Business days have
elapsed since such First Rating Trigger Event occurred, or (B) a First Rating
Trigger Event with respect to S&P has occurred and is continuing for at least 30
days or a Second Rating Trigger Event with respect to S&P has occurred and is
continuing, the Threshold with respect to Party A shall be zero.

"Threshold" means with respect to Party B, infinity.

(C) "Minimum Transfer Amount" means with respect to Party A: [__________], and
with respect to Party B: [__________], provided, that if the aggregate principal
balance of Certificates rated by S&P ceases to be more than USD [__________],
the "Minimum Transfer Amount" shall be [__________] and provided further that if
a Party is a Defaulting Party, or the Affected Party under an Additional
Termination Event, the Minimum Transfer Amount for such party shall be zero.

(D) Rounding. The Delivery Amount and the Return Amount will be rounded up and
down, respectively, to the nearest integral multiple of $[__________].

(c) (i) External Verification. Notwithstanding anything to the contrary in the
definitions of Valuation Agent or Valuation Date, at any time at which Party A
(or, to the extent applicable, its Credit Support Provider) does not have a
long-term unsubordinated and unsecured debt rating of at least "BBB+" from S&P,
the Valuation Agent shall (A) calculate the Secured Party's Exposure and the S&P
Value (as defined below) of Posted Credit Support on each Valuation Date based
on internal marks and (B) verify such calculations with external marks monthly
by obtaining on the last Local Business Day of each calendar month two external
marks for each Transaction to which this Annex relates and for all Posted Credit
Support; such verification of the Secured Party's Exposure shall be based on the
higher of the two external marks. Each external mark in respect of a Transaction
shall be obtained from an independent Reference Market-maker that would be
eligible and willing to enter into such Transaction in the absence of the
current derivative provider, provided that an external mark may not be obtained
from the same Reference Market-maker more than four times in any 12-month
period. The Valuation Agent shall obtain these external marks directly or
through an independent third party, in either case at no cost to Party B. The
Valuation Agent shall calculate on each Valuation Date (for purposes of this
paragraph, the last Local Business Day in each calendar month referred to above
shall be considered a Valuation Date) the Secured Party's Exposure based on the
greater of the Valuation Agent's internal marks and the external marks

                                     M-3-10

<PAGE>

received. If the S&P Value on any such Valuation Date of all Posted Credit
Support then held by the Secured Party is less than the S&P Collateral Amount on
such Valuation Date (in each case as determined pursuant to this paragraph),
Party A shall, within three Local Business Days of such Valuation Date, Transfer
to the Secured Party Eligible Credit Support having an S&P Value as of the date
of Transfer at least equal to such deficiency.

(ii) Notice to S&P. At any time at which Party A (or, to the extent applicable,
its Credit Support Provider) does not have a long-term unsubordinated and
unsecured debt rating of at least "BBB+" from S&P, the Valuation Agent shall
provide to S&P not later than the Notification Time on the Local Business Day
following each Valuation Date its calculations of the Secured Party's Exposure
and the S&P Value of any Eligible Credit Support or Posted Credit Support for

marks received pursuant to the preceding paragraph.

(d) Valuation and Timing.

(i) "Valuation Agent" means Party A.

(ii) "Valuation Date" means: any Local Business Day.

(iii) "Valuation Time" means the close of business on the Local Business Day
before the Valuation Date or date of calculation, as applicable; provided,
however, that the calculations of Value and Exposure will be made as of

(iv) "Notification Time" means 9:00 a.m., New York time, on a Local Business
Day.

          "Market Quotation" means, with respect to one or more Terminated
          Transactions, an offer which, when made, is capable of becoming

          is (1) made by a Reference Market-maker that is an Eligible
          Replacement, (2) for an amount that would be paid to Party B

                                      Q-11

<PAGE>

          consideration of an agreement between Party B and such Reference
          Market-maker to enter into a transaction (the "Replacement
          Transaction") that would have the effect of preserving for such party
          the economic equivalent of any payment or delivery (whether the
          underlying obligation was absolute or contingent and assuming the
          satisfaction of each applicable condition precedent) by the parties
          under Section 2(a)(i) in respect of such Terminated Transactions or
          group of Terminated Transactions that would, but for the occurrence of
          the relevant Early Termination Date, have been required after that
          date, (3) made on the basis that Unpaid Amounts in respect of the
          Terminated Transaction or group of Transactions are to be excluded
          but, without limitation, any payment or delivery that would, but for
          the relevant Early Termination Date, have been required (assuming
          satisfaction of each applicable condition precedent) after that Early
          Termination Date is to be included and (4) made in respect of a
          Replacement Transaction with commercial terms substantially the same
          as those of this Agreement (save for the exclusion of provisions
          relating to Transactions that are not Terminated Transactions)."

          (B) The definition of "Settlement Amount" shall be deleted in its
          entirety and replaced with the following:

          "Settlement Amount" means, with respect to any Early Termination Date,
          an amount (as determined by Party B) equal to:

               (1) If a Market Quotation for the relevant Terminated Transaction
               or group of Terminated Transactions is selected by Party A and
               accepted by Party B so as to become legally binding on or before
               the day falling ten Local Business Days after the day on which
               the Early Termination Date is designated (or such later day as
               Party B may specify in writing to Party A, which in any event
               will not be later than the Early Termination Date) (such day, the
               "Latest Settlement Amount Determination Day"), the Termination
               Currency Equivalent of the amount (whether positive or negative)
               of such Market Quotation; or

               (2) If no Market Quotation for the relevant Terminated
               Transaction or group of Terminated Transactions has been selected
               by Party A and accepted by Party B so as to become legally
               binding on or before the Latest Settlement Amount Determination
               Day, Party B's Loss (whether positive or negative and without
               reference to any Unpaid amounts) for the relevant Terminated
               Transaction or group of Terminated Transactions.

                                      Q-12

<PAGE>

          (C) For the purpose of clause (4) of the definition of Market
          Quotation, Party B shall determine in its sole discretion, acting in a
          commercially reasonable manner, whether a Firm Offer is made in
          respect of a Replacement Transaction with commercial terms
          substantially the same as those of this Agreement (save for the
          exclusion of provisions relating to Transactions that are not
          Terminated Transactions).

          (D) Party B undertakes to use its reasonable efforts to obtain at
          least one Market Quotation before the Latest Settlement Amount
          Determination Day. Party B will be deemed to have discharged its
          obligations under the preceding sentence if it requests Party A to
          obtain Market Quotations, where such request is made in writing within
          two Local Business Days after the day on which the Early Termination
          Date is designated. If Party B requests Party A in writing to obtain
          Market Quotations, Party A shall use its reasonable efforts to do so
          before the Latest Settlement Amount Determination Day.

          (E) Any amount calculated as being due in respect of an Early
          Termination Date will be payable in accordance with Section 6(d)(ii),
          provided that if such payment is owed to Party B, it will be payable
          on the day that notice of the amount payable is given to Party A.

          (F) If the Settlement Amount is a negative number, Section 6(e)(i)(3)
          of this Agreement shall be deleted in its entirety and replaced with
          the following:

          Second Method and Market Quotation. If Second Method and Market
          Quotation apply, (1) Party B shall pay to Party A an amount equal to
          the absolute value of the Settlement Amount in respect of the
          Terminated Transactions, (2) Party B shall pay to Party A the
          Termination Currency Equivalent of the Unpaid Amounts owing to Party A
          and (3) Party A shall pay to Party B the Termination Currency

     unsubordinated debt ceases to be rated at least "F1" by Fitch.

     "Rating Agency Condition" means, with respect to any particular proposed
     act or omission to act hereunder, that the party acting or failing to act
     must consult with each of the Rating Agencies then providing a rating of
     the Certificates and receive from each such Rating Agency a prior written
     confirmation that the proposed action or inaction would not cause a
     downgrade or withdrawal of the then-current rating of the Certificates.

     A "Second Rating Trigger Event" shall occur with respect to Party A (or any
     applicable credit support provider), if (A) Party A's long-term unsecured
     and unsubordinated debt ceases to be rated at least "BBB-" or Party A's
     short-term unsecured and unsubordinated debt ceases to be rated at least
     "A-3" or is withdrawn by S&P or (B) Party A's long-term unsecured and
     unsubordinated debt ceases to be rated at least A3 or Party A's short-term
     unsecured and unsubordinated debt ceases to be rated at least "Prime-2" (or
     if Party A does not have a short-term unsecured and unsubordinated debt
     rating from Moody's, its long-term unsecured and unsubordinated debt ceases
     to be rated at least A3).

     (ii) If a First Rating Trigger Event occurs with respect to Party A (or any
          applicable Credit Support Provider), then (unless, within 30 days of
          such First Rating Trigger Event, each of Standard and Poor's, a
          Division of McGraw-Hill Companies, Inc. ("S&P"), Moody's Investors
          Service, Inc. ("Moody's") and

          Fitch Ratings ("Fitch") (each a "Rating Agency") has reconfirmed its
          rating of the Certificates which was in effect immediately prior to
          such First Rating Trigger Event) Party A shall, within (30) days of
          such First Rating Trigger Event, at its own expense, (A) obtain an
          Eligible Guarantee in respect of all of Party A's present and future
          obligations under this Agreement, subject to the Rating Agency
          Condition (B) transfer all or substantially all of its rights and
          obligations with respect to this Agreement to an Eligible Replacement
          (provided that Party B shall determine in its sole discretion, acting
          in a commercially reasonable manner, whether or not a transfer relates
          to all or substantially all of Party A's rights and obligations under
          this Agreement), subject to the Rating Agency Condition or (C) post
          collateral in accordance with the Credit Support Annex to this
          Agreement, subject to the Rating Agency Condition in respect of S&P
          and Fitch only.

     (iii) If a Second Rating Trigger Events occurs with respect to Party A (or
          any applicable Credit Support Provider), then Party A will at its own
          cost use commercially reasonable efforts to, as soon as reasonably
          practicable, either (A) obtain an Eligible Guarantee in respect of all
          of Party A's present and future obligations under this Agreement,
          subject to the Rating Agency Condition, or (B) transfer all or
          substantially all of its rights and obligations with respect to this
          Agreement to an Eligible Replacement (provided that Party B shall
          determine in its sole discretion, acting in a commercially reasonable
          manner, whether or not a transfer relates to all or substantially all
          of Party A's rights and obligations under this Agreement), subject to
          the Rating Agency Condition.

(k)  Compliance with Regulation AB.

     (i)  Party A acknowledges that for so long as there are reporting
          obligations with respect to this Transaction under Regulation AB
          ("Regulation AB") under the Securities Act of 1933, as amended, and
          the Securities Exchange Act of 1934, as amended (the "1934 Act"), the
          Depositor is required under Regulation AB, to disclose certain
          information set forth in Regulation AB regarding Party A or its group
          of affiliated entities, if applicable, depending on the aggregate
          "significance percentage" of this Agreement and any other derivative
          contracts between Party A or its group of affiliated entities, if
          applicable, and Party B, as calculated from time to time in accordance
          with Item 1115 of Regulation AB.

     (ii) If the Depositor determines, reasonably and in good faith, that the
          significance percentage of this Agreement has increased to nine (9)
          percent, then the

                                      Q-23

<PAGE>

          Depositor may request from Party A (such request, a "Swap Disclosure
          Request") on a Business Day after the date of such determination the
          same information set forth in Item 1115(b) of Regulation AB (such
          requested information, subject to the last sentence of this paragraph,
          the "Swap Financial Disclosure") that would have been required if the
          significance percentage had in fact increased to ten (10) percent.
          Party B, the Depositor or any of its agents shall provide Party A with
          the calculations and any other information reasonably requested by
          Party A with respect to the Depositor's determination that led to the
          Swap Disclosure Request. The parties hereto further agree that the
          Swap Financial Disclosure provided to meet the Swap Disclosure Request
          may be, solely at Party A's option, either the information set forth
          in Item 1115(b)(1) or Item 1115(b)(2) of Regulation AB.

     (iii) So long as there are reporting obligations with respect to this
          Transaction under the 1934 Act, if the Depositor determines,
          reasonably and in good faith, that the significance percentage of this
          Agreement has increased to 19 percent, then the Depositor may make a
          Swap Disclosure Request to Party A on such date of determination for
          Swap Financial Disclosure that would have been required if the
          significance percentage had in fact increased to 20 percent (and,
          accordingly, consists of the information set forth in Item 1115(b)(2)
          of Regulation AB). Party B or the Depositor shall provide Party A with
          the calculations and any other information reasonably requested by
          Party A with respect to the Depositor's determination that led to the
          Swap Disclosure Request.

     (iv) Upon the occurrence of a Swap Disclosure Request, Party A, at its own
          expense, shall (i) provide the Depositor with the Swap Financial
          Disclosure, (ii) subject to Rating Agency Confirmation, secure another
          entity to replace Party A as party to this Agreement on terms
          substantially similar to this Agreement which entity is able to
          provide the Swap Financial Disclosure or (iii) subject to Rating
          Agency Confirmation, obtain a guaranty of Party A's obligations under
          this Agreement from an affiliate of Party A that is able to provide
          the Swap Financial Disclosure, such that disclosure provided in
          respect of the affiliate will satisfy any disclosure requirements
          applicable to Party A, and cause such affiliate to provide Swap
          Financial Disclosure. For purposes of clause (ii) above, the parties
          agree that National Westminster Bank Plc ("NatWest") shall be an
          acceptable replacement for Party A, so long as NatWest satisfies the
          conditions specified in such clause (ii). If permitted by Regulation
          AB, any required Swap Financial Disclosure may be provided by
          incorporation by reference from reports filed pursuant to the 1934
          Act.

                                      Q-24
<PAGE>

     (v)  All information provided pursuant to clause (iv) shall be in a form
          suitable for conversion to the format required for filing by the
          Depositor with the Commission via the Electronic Data Gathering and
          Retrieval System (EDGAR). The parties hereto acknowledge that
          electronic files in Adobe Acrobat format will be deemed to satisfy the
          requirements of this Part 5(k)(v).

(l)  Severability. If any term, provision, covenant, or condition of the
     Agreement, or the application thereof to any other party or circumstance,
     shall be held invalid or unenforceable (in whole or in part) for any
     reason, the remaining terms, provisions, covenants, and conditions hereof
     shall continue in full force and effect as if the Agreement has been
     executed with the invalid or unenforceable provision portion eliminated, so
     long as the Agreement as so modified continues to express, without material
     change, the original intentions of the parties as to the subject matter of
     the Agreement and the deletion of such portion of the Agreement will not
     substantially impair the respective benefits or expectations of the
     parties. The parties shall endeavor to engage in good faith negotiations to
     replace any invalid or unenforceable term, provision, covenant or
     conditions with a valid or enforceable term, provision, covenant or
     condition, the economic effect of which comes as close as possible to that
     of the invalid or unenforceable term, provision, covenant or condition.

(m)  MLML Shall Not Benefit. The parties hereto agree and acknowledge that
     amounts paid hereunder are not intended to benefit the holder of any class
     of certificates rated by any rating agency if such holder is Merrill Lynch
     Mortgage Lending, Inc. ("MLML") or any of its affiliates. If MLML or any of
     its affiliates receives any such amounts, it will promptly remit (or, if
     such amounts are received by an affiliate of MLML, MLML hereby agrees that
     it will cause such affiliate to promptly remit) such amounts to the
     Trustee, whereupon the Trustee will promptly remit such amounts to Party A.

(n)  In the event that the transaction to which the Pooling Agreement relates
     does not occur, and the Merrill Lynch Mortgage Investors Trust, Series
     2006-HE6 is not formed, Party A and MLML agree that MLML shall become Party
     B under this Agreement.

(o)  Transfer. Neither Party A nor Party B is permitted to amend, assign, novate
     or transfer (whether by way of security or otherwise) as a whole or in part
     any of its rights, obligations or interests under this Agreement or any
     Transaction without the prior written consent of the other party; provided,
     however, that (i) Party A may make such a transfer or assignment of this
     Agreement pursuant to a consolidation or amalgamation with, or merger with
     or into, or transfer of substantially all of its assets to, another entity,
     or an incorporation, reincorporation or reconstitution, and (ii) Party A
     may transfer or assign

                                      Q-25

<PAGE>

     this Agreement to any Person, including, without limitation, another of
     Party A's offices, branches or affiliates (any such Person, office, branch
     or affiliate, a "Transferee") on at least five Business Days' prior written
     notice to Party B; provided that, with respect to clause (ii), (A) as of
     the date of such transfer the Transferee will not be required to withhold
     or deduct on account of a Tax from any payments under this Agreement unless
     the Transferee will be required to make payments of additional amounts
     pursuant to Section 2(d)(i)(4) of the Master Agreement in respect of such
     Tax (B) a Termination Event or Event of Default does not occur under this
     Agreement as a result of such transfer; (C) such notice is accompanied by a
     written instrument pursuant to which the Transferee acquires and assumes
     the rights and obligations of Party A so transferred; and (D) Party A will
     be responsible for any costs or expenses incurred in connection with such
     transfer. Party B will execute such documentation as is reasonably deemed
     necessary by Party A for the effectuation of any such transfer.
     Notwithstanding the foregoing, no transfer by either party shall be made
     unless the transferring party obtains a written acknowledgment from each of
     the Rating Agencies that, notwithstanding such transfer, the then-current
     ratings of the Certificates will not be reduced or withdrawn.

     Except as specified otherwise in the documentation evidencing a transfer or
     assignment, a transfer or assignment of all the obligations of Party A will
     constitute an acceptance and assumption of such obligations (and any
     related interests so transferred) by the Transferee, a novation of the
     transferee in place of Party A with respect to such obligations (and any
     related interests so transferred), and a release and discharge by Party B
     of Party A from, and an agreement by Party B not to make any claim for
     payment, liability, or otherwise against Party A with respect to, such
     obligations from and after the effective date of the transfer.

(p)  Amendment of the Pooling and Servicing Agreement. Party B shall not amend
     the Pooling and Servicing Agreement without Party A's prior written
     consent, where such consent is required under the terms of the Pooling
     Agreement.

(q)  Counterparts. This letter agreement may be executed in several
     counterparts, each of which shall be deemed an original but all of which
     together shall constitute one and the same instrument.

(r)  USA PATRIOT Act Notice. Party A hereby notifies Party B that pursuant to
     the requirements of the USA PATRIOT ACT (Title III of Pub. L. 107-56
     (signed into law October 26, 2001)) (the "Act"), it is required to obtain,
     verify and record information that identifies Party B, which information
     includes the name and address of Party B and other information that will
     allow Party A to identify Party B in accordance with the Act.

"Independent Amount" means with respect to Party B: Not Applicable.

(B) "Threshold" means with respect to Party A, infinity, provided that for so

the Minimum Transfer Amount for such party shall be zero.

(D) Rounding. The Delivery Amount and the Return Amount will be rounded up and
down, respectively, to the nearest integral multiple of $[_____].

(c) (i) External Verification. Notwithstanding anything to the contrary in the
definitions of Valuation Agent or Valuation Date, at any time at which Party A
(or, to the extent applicable, its Credit Support Provider) does not have a
long-term unsubordinated and unsecured debt rating of at least "BBB+" from S&P,
the Valuation Agent shall (A) calculate the Secured Party's Exposure and the S&P
Value (as defined below) of Posted Credit Support on each Valuation Date based
on internal marks and (B) verify such calculations with external marks monthly
by obtaining on the last Local Business Day of each calendar month two external
marks for each Transaction to which this Annex relates and for all Posted Credit
Support; such verification of the Secured Party's Exposure shall be based on the
higher of the two external marks. Each external mark in respect of a Transaction
shall be obtained from an independent Reference Market-maker that would be
eligible and willing to enter into such Transaction in the absence of the
current derivative provider, provided that an external mark may not be obtained
from the same Reference Market-maker more than four times in any 12-month
period. The Valuation Agent shall obtain these external marks directly or
through an independent third party, in either case at no cost to Party B. The
Valuation Agent shall calculate on each Valuation Date (for purposes of this
paragraph, the last Local Business Day in each calendar month referred to above
shall be considered a Valuation Date) the Secured Party's Exposure based on the
greater of the Valuation Agent's internal marks and the external marks received.
If the S&P Value on any such Valuation Date of all Posted Credit Support then
held by the Secured Party is less than the S&P Collateral Amount on such
Valuation Date (in each case as determined pursuant to this paragraph), Party A
shall, within three Local Business Days of such Valuation Date, Transfer to

                                      Q-31

Transfer at least equal to such deficiency.

(ii) Notice to S&P. At any time at which Party A (or, to the extent applicable,
its Credit Support Provider) does not have a long-term unsubordinated and
unsecured debt rating of at least "BBB+" from S&P, the Valuation Agent shall
provide to S&P not later than the Notification Time on the Local Business Day
following each Valuation Date its calculations of the Secured Party's Exposure
and the S&P Value of any Eligible Credit Support or Posted Credit Support for
that Valuation Date. The Valuation Agent shall also provide to S&P any external
marks received pursuant to the preceding paragraph.

(d) Valuation and Timing.

(i) "Valuation Agent" means Party A.

(ii) "Valuation Date" means: any Local Business Day.

(iii) "Valuation Time" means the close of business on the Local Business Day
before the Valuation Date or date of calculation, as applicable; provided,
however, that the calculations of Value and Exposure will be made as of
approximately the same time on the same date.

(iv) "Notification Time" means 9:00 a.m., New York time, on a Local Business
Day.

(d) Conditions Precedent and Secured Party's Rights and Remedies. For purposes
of Paragraph 8(a), each Termination Event will be a "Specified Condition" for
the Pledgor, if the Secured Party has designated an Early Termination Date in
connection with the Termination Event. For all other purposes of this Annex,
each Termination Event specified below with respect to a party will be a
