                         POOLING AND SERVICING AGREEMENT

     This Pooling and Servicing Agreement is dated as of October 1, 2007 (the
"Agreement"), among MERRILL LYNCH MORTGAGE INVESTORS, INC., as depositor (the
"Depositor"), WELLS FARGO BANK, N.A., as master servicer (in such capacity, the
"Master Servicer") and as securities administrator (in such capacity, the
"Securities Administrator") and HSBC BANK USA, NATIONAL ASSOCIATION, as trustee
(the "Trustee").

                              PRELIMINARY STATEMENT

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

     As provided herein, the Securities Administrator shall elect that the Trust
Fund be treated for federal income tax purposes as consisting of (i) two real
estate mortgage investment conduits (each a "REMIC" or, in the alternative,
"REMIC 1" and the "Upper Tier REMIC," respectively) in a tiered structure, (ii)
the right to receive payments distributable to the Class P Certificates and
(iii) the grantor trust described in Section 9.12 hereof. The Certificates,
other than the Class A-R and Class P Certificates, shall represent ownership of
regular interests in the Upper Tier REMIC. The Class X Certificates shall also
represent certain non-REMIC rights described in Section 9.12 hereof. The Class
A-R Certificate represents the sole class of residual interest in each of REMIC
1 and the Upper Tier REMIC.

     The Upper Tier REMIC shall hold as its assets the several classes of
uncertificated REMIC 1 Regular Interests. REMIC 1 shall hold as its assets the
property of the Trust Fund other than the REMIC 1 Interests and other than the
right to receive payments distributable to the Class P Certificates.

     Each Upper Tier REMIC Regular Interest is hereby designated as a regular
interest in the Upper Tier REMIC for purposes of the REMIC Provisions. Each
REMIC 1 Regular Interest is hereby designated as a regular interest in REMIC 1
for purposes of the REMIC Provisions.

     The Class LT1-R Interest is hereby designated as the sole class of residual
interest in REMIC 1 for purposes of the REMIC Provisions. The Class A-R
Certificate, other than the


                                      -1-

<PAGE>

portion thereof representing the right to receive payments in respect of the
Class LT1-R Interest, is hereby designated as the sole class of residual
interest in the Upper Tier REMIC for purposes of the REMIC provisions. The Class
A-R Certificate will also represent the Class LT1-R Interest.

THE REMIC 1 INTERESTS

     The following table sets forth (or describes) the class designation,
interest rate, initial principal balance and Classes of Corresponding
Certificates for each class of REMIC 1 Interests:

                                      -32-

<PAGE>

          (i) For any Distribution Date prior to the Distribution Date in
     November 2014 (unless the Certificate Principal Balances of the Senior
     Certificates have been reduced to zero), 0%.

          (ii) For any Distribution Date for which clause (i) does not apply,
     and on which any Class of Subordinate Certificates are outstanding:

               (a) in the case of the Class of Subordinate Certificates then
          outstanding with the Highest Priority and each other Class of
          Subordinate Certificates for which the related Prepayment Distribution
          Trigger has been satisfied, a fraction, expressed as a percentage, the
          numerator of which is the Certificate Principal Balance of such Class
          immediately prior to such date and the denominator of which is the sum
          of the Certificate Principal Balances immediately prior to such date
          of (1) the Class of Subordinate Certificates then outstanding with the
          Highest Priority and (2) all other Classes of Subordinate Certificates
          for which the respective Prepayment Distribution Triggers have been
          satisfied; and

               (b) in the case of each other Class of Subordinate Certificates
          for which the Prepayment Distribution Triggers have not been
          satisfied, 0%; and

          (iii) Notwithstanding the foregoing, if the application of the
     foregoing percentages on any Distribution Date as provided in Section 6.01
     of this Agreement (determined without regard to the proviso in the
     definition of "Subordinate Principal Distribution Amount") would result in
     a distribution in respect of principal of any Class or Classes of
     Subordinate Certificates in an amount greater than the remaining
     Certificate Principal Balance thereof (any such class, a "Maturing Class"),
     then: (a) the Subordinate Prepayment Percentage of each Maturing Class
     shall be reduced to a level that, when applied as described above, would
     exactly reduce the Certificate Principal Balance of such Class to zero; (b)
     the Subordinate Prepayment Percentage of each other Class of Subordinate
     Certificates (any such Class, a "Non-Maturing Class") shall be recalculated
     in accordance with the provisions in paragraph (ii) above, as if the
     Certificate Principal Balance of each Maturing Class had been reduced to
     zero (such percentage as recalculated, the "Recalculated Percentage"); (c)
     the total amount of the reductions in the Subordinate Prepayment
     Percentages of the Maturing Class or Classes pursuant to clause (a) of this
     sentence, expressed as an aggregate percentage, shall be allocated among
     the Non-Maturing Classes in proportion to their respective Recalculated
     Percentages (the portion of such aggregate reduction so allocated to any
     Non-Maturing Class, the "Adjustment Percentage"); and (d) for purposes of
     such Distribution Date, the Subordinate Prepayment Percentage of each
     Non-Maturing Class shall be equal to the sum of (1) the Subordinate
     Prepayment Percentage thereof, calculated in accordance with the provisions
     in paragraph (ii) above as if the Certificate Principal Balance of each
     Maturing Class had not been reduced to zero, plus (2) the related
     Adjustment Percentage.

     Subordinate Principal Distribution Amount: With respect to any Distribution
Date and each Class of Class M Certificates and Class B Certificates, the sum of
the following:

     Percentage for such Class and (y) the aggregate of the following amounts:

                    (1) the principal portion of each Monthly Payment due during
          the related Due Period on each Outstanding Mortgage Loan, whether or
          not received on or prior to the related Determination Date, minus the
          principal portion of any Debt Service Reduction;

                    (2) the Stated Principal Balance of any Mortgage Loan
          repurchased during the related Prepayment Period pursuant to Section
          2.02 or 2.03 or pursuant to the related Servicing Agreement less any
          portion of such Stated Principal Balance applied to offset Deferred
          Interest on any Distribution Date; and

                    (3) the principal portion of all other unscheduled
          collections including Subsequent Recoveries (other than Principal
          Prepayments in Full and Curtailments and amounts received in
          connection with the liquidation or other disposition of a Mortgage
          Loan, including without limitation Insurance Proceeds, Liquidation
          Proceeds and REO Proceeds) received during the related Prepayment
          Period to the extent applied by the related Servicer as recoveries of
          principal of the related Mortgage Loan pursuant to the related
          Servicing Agreement;

               (ii) such Class's pro rata share, based on the Certificate
     Principal Balance of each Class of Subordinate Certificates then
     outstanding, of, with respect to each Mortgage Loan for which a liquidation
     or other disposition occurred during the related Prepayment Period and did
     not result in any Extraordinary Losses, an amount equal to the related
     unscheduled collections (including without limitation Insurance Proceeds,
     Liquidation Proceeds and REO Proceeds) to the extent applied by the related
     Servicer as recoveries of principal of the related Mortgage Loan pursuant
     to the related Servicing Agreement, to the extent such collections are not
     otherwise distributed to the Senior Certificates;

               (iii) the portion of Principal Prepayments in Full and
     Curtailments of the Mortgage Loans received in the related Prepayment
     Period that are not applied to offset Deferred Interest on any Distribution
     Date, to the extent not payable to the Senior Certificates; and

               (iv) any amounts described in clauses (i), (ii) and (iii) as
     determined for any previous Distribution Date, that remain undistributed to
     the extent that such amounts are not attributable to Realized Losses which
     have been allocated to a Class of Subordinate Certificates;

provided, however, that such amount shall in no event exceed the outstanding
Certificate Principal Balance of such Class of Certificates immediately prior to
such date.

                             CONVEYANCE OF MORTGAGE
                    LOANS; ORIGINAL ISSUANCE OF CERTIFICATES

     Section 2.01 Conveyance of Mortgage Loans to Trustee.

     (a) The Depositor concurrently with the execution and delivery of this
Agreement, sells, transfers and assigns to the Issuing Entity without recourse
all its right, title and interest in and to (i) the Mortgage Loans identified in
the Mortgage Loan Schedule, including all interest and principal due with
respect to the Mortgage Loans after the Cut-off Date, but excluding any payments

<PAGE>

secure the Mortgage Loans, including the Mortgaged Properties to have and to
hold, in trust. Although it is the intent of the parties to this Agreement that
the conveyance of the Depositor's right, title and interest in and to the
Mortgage Loans and other assets in the Trust Fund pursuant to this Agreement
shall constitute a purchase and sale and not a loan, in the event that such
conveyance is deemed to be a loan, it is the intent of the parties to this
Agreement that the Depositor shall be deemed to have granted to the Trustee a
first priority perfected security interest in all of the Depositor's right,
title and interest in, to and under the Mortgage Loans and other assets in the
Trust Fund, and that this Agreement shall constitute a security agreement under
applicable law.

     (b) In connection with the above transfer and assignment, the Depositor

provided that the endorsement is completed within 60 days of the Closing Date;
(x) in lieu of the original Mortgage, assignments to the Trustee or its
Custodian, as applicable, or intervening assignments thereof which have been
delivered, are being delivered or will, upon receipt of recording information
relating to the Mortgage required to be included thereon, be delivered to
recording offices for recording and have not been returned to the Depositor in
time to permit their delivery as specified above, the Depositor may deliver a
true copy thereof with a certification by the Depositor on the face of such
copy, substantially as follows: "Certified to be a true and correct copy of the
original, which has been transmitted for recording"; and (y) in lieu of the
Mortgage, assignment to the Trustee or intervening assignments thereof, if the
applicable jurisdiction retains the originals of such

<PAGE>

documents (as evidenced by a certification from the Depositor or the Master
Servicer, to such effect) the Depositor may deliver photocopies of such
documents containing an original certification by the judicial or other
governmental authority of the jurisdiction where such documents were recorded;
and provided, further, however, that in the case of Mortgage Loans which have
been prepaid in full after the Cut-off Date and prior to the Closing Date, the
Depositor, in lieu of delivering the above documents, may deliver to the Trustee

Account on the Closing Date. The Depositor shall deliver such original documents
(including any original documents as to which certified copies had previously
been delivered) to the Trustee or its Custodian, as applicable, promptly after
they are received. As of the date hereof, recordation of the assignment of the
Mortgage Loans to the Trustee or the Custodian, as applicable, is not required
in any state by either Rating Agency to obtain the initial rating on the
Certificates (upon which statement the Master Servicer, the Trustee and the
Custodian may each conclusively rely).

     If any original Mortgage Note referred to in Section 2.01(b)(I)(i) or
2.01(b)(II)(i) above cannot be located, the obligations of the Depositor to
deliver such documents shall be deemed to be satisfied upon delivery to the
Trustee or its Custodian, as applicable, of a photocopy of such Mortgage Note,
if available, with a lost note affidavit. If any of the original Mortgage Notes
for which a lost note affidavit was delivered to the Trustee or its Custodian,
as applicable, is subsequently located, such original Mortgage Note shall be
delivered to the Trustee or its Custodian, as applicable, within three Business
Days.

     (c) The parties hereto agree that it is not intended that any mortgage loan
be included in the Trust Fund that is, without limitation, a "High Cost Loan" as
defined by the Home Ownership and Equity Protection Act of 1994 or any other
applicable anti-predatory lending laws, including but not limited to (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

Indiana High Cost Home Loan Law effective January 1, 2005.

     (d) Notwithstanding anything to the contrary contained herein, the parties

performed by the Custodian(s) pursuant to the terms and conditions of the
Custodial Agreement(s).

     Section 2.02 Acceptance of Mortgage Loans by Trustee.

     (a) The Trustee acknowledges the sale, transfer and assignment of the Trust
Fund to it by the Depositor and its receipt thereof, subject to further review
and the exceptions which may be noted pursuant to the procedures described
below, and declares that it, or the Custodian on its behalf, holds the documents
(or certified copies thereof) delivered to it pursuant to Section 2.01, and
declares that it will continue to hold those documents and any amendments,


                                      -40-

<PAGE>

replacements or supplements thereto and all other assets of the Trust Fund
delivered to it as Trustee in trust for the use and benefit of all present and
future Holders of the Certificates. On or before the Closing Date (or, with
respect to any Substitute Mortgage Loan, within five Business Days after the
receipt by the Trustee or Custodian thereof), the Trustee agrees, for the
benefit of the Certificateholders, to review or cause to be reviewed by the
Custodian on its behalf (under the Custodial Agreement), each Mortgage File
delivered to it and to execute and deliver, or cause to be executed and
delivered, to the Depositor and, if applicable, to the Trustee, on the Closing
Date an Initial Certification. In conducting such review, the Trustee or
Custodian will certify as to each Mortgage Loan listed in the Mortgage Loan
Schedule (other than any Mortgage Loan paid in full or any Mortgage Loan
specifically identified in the exception report annexed thereto as not being
covered by such certification), (i) all documents constituting part of such
Mortgage File (other than such documents described in Section 2.01(b)(I)(iii))
required to be delivered to it pursuant to this Agreement are in its possession,
provided that with respect to the documents described in Section 2.01(b)(I)(v),
(vi), (viii) and (ix) and 2.01(b)(II)(viii) and (ix) to the extent the Trustee
or the Custodian on its behalf has actual knowledge that such documents exist,
(ii) such documents have been reviewed by it and are not torn, mutilated,
defaced or otherwise altered (except if initialed by the obligor) and appear to
relate on their face to such Mortgage Loan, (iii) based on its examination and
only as to the foregoing, the information set forth in the Mortgage Loan
Schedule corresponding to the loan number for the Mortgage Loan, the Mortgagor's
name, including the street address but excluding the zip code, the Mortgage
Interest Rate and the original principal balance of the Mortgage Loan accurately
reflects information set forth in the Mortgage File and (iv) with respect to
Mortgage Loans with a Mortgage Interest Rate subject to adjustment, the Gross
Margin, the lifetime cap and the periodic cap for such Mortgage Loan. In
performing any such review, the Trustee, or the Custodian, as its agent, may
conclusively rely on the purported due execution and genuineness of any such
document and on the purported genuineness of any signature thereon.
Notwithstanding anything to the contrary in this Agreement, it is herein
acknowledged that, in conducting such review, the Trustee or the Custodian on
its behalf is under no duty or obligation to inspect, review or examine any such
documents, instruments, certificates or other papers to determine whether they
are genuine, enforceable, or appropriate for the represented purpose or whether
they have actually been recorded or that they are other than what they purport
to be on their face, or to determine whether any Person executing any documents
is authorized to do so or whether any signature is genuine. If the Trustee or
the Custodian, as its agent, finds any document constituting part of the
Mortgage File not to have been executed or received, or to be unrelated to the
Mortgage Loans identified in Exhibit B or to appear to be defective on its face,
the Trustee or the Custodian, as its agent, shall promptly notify the Seller.

     In accordance with the Mortgage Loan Purchase Agreement, the Seller shall
correct or cure any such defect within ninety (90) days from the date of notice
from the Trustee or the Custodian, as its agent, of the defect and if the Seller
fails to correct or cure the defect within such period, and such defect
materially and adversely affects the interests of the Certificateholders in the
related Mortgage Loan, the Trustee, shall enforce the Seller's obligation
pursuant to the Mortgage Loan Purchase Agreement, within 90 days from the
Trustee's or the Custodian's notification, to purchase such Mortgage Loan at the
Purchase Price; provided that, if such defect would cause the Mortgage Loan to
be other than a "qualified mortgage" as defined in Section 860G(a)(3) of the
Code, any such cure or repurchase must occur within 90 days from the date such
breach was discovered; provided, however, that if such defect relates solely to
the


                                      -41-

inability of the Seller to deliver the original Security Instrument or
intervening assignments thereof, or a certified copy because the originals of
such documents, or a certified copy have not been returned by the applicable
jurisdiction, the Seller shall not be required to purchase such Mortgage Loan if
the Seller delivers such original documents or certified copy promptly upon
receipt, but in no event later than 360 days after the Closing Date. The
foregoing repurchase obligation shall not apply in the event that the Seller
cannot deliver such original or copy of any document submitted for recording to
the appropriate recording office in the applicable jurisdiction because such
document has not been returned by such office; provided that the Seller shall
instead deliver a recording receipt of such recording office or, if such receipt
is not available, a certificate confirming that such documents have been
accepted for recording, and delivery to the Trustee or the Custodian, as its
agent, shall be effected by the Seller within thirty days of its receipt of the
original recorded document.

     (b) No later than 180 days after the Closing Date, the Trustee or the
Custodian, as its agent, will review, for the benefit of the Certificateholders,
the Mortgage Files delivered to it and will execute and deliver or cause to be
executed and delivered to the Depositor and, if applicable, to the Trustee, a
Final Certification. In conducting such review, the Trustee or the Custodian, as
its agent, will certify as to each Mortgage Loan listed in the Mortgage Loan
Schedule (other than any Mortgage Loan paid in full or any Mortgage Loan
specifically identified in the exception report annexed thereto as not being
covered by such certification), that (i) all documents constituting part of such
Mortgage File (other than such documents described in Section 2.01(b)(I)(v) and
(ix)) required to be delivered to it pursuant to this Agreement are in its
possession, provided that with respect to the documents described in Section
2.01(b)(I)(v), (vi), (viii) and (ix) and 2.01(b)(II)(viii) and (ix) to the
extent the Trustee or the Custodian on its behalf has actual knowledge that such
documents exist, (ii) such documents have been reviewed by it and are not torn,
mutilated, defaced or otherwise altered (except if initialed by the obligor) and
appear regular on their face and relate to such Mortgage Loan, (iii) based on
its examination and only as to the foregoing, the information set forth in the
Mortgage Loan Schedule corresponding to the loan number for the Mortgage Loan,
the Mortgagor's name, including the street address but excluding the zip code,
the Mortgage Interest Rate and the original principal balance of the Mortgage
Loan accurately reflects information set forth in the Mortgage File. In
performing any such review, the Trustee, or the Custodian, as its agent, may
conclusively rely on the purported due execution and genuineness of any such
document and on the purported genuineness of any signature thereon.
Notwithstanding anything to the contrary in this Agreement, it is herein
acknowledged that, in conducting such review, the Trustee or the Custodian on
its behalf is under no duty or obligation (i) to inspect, review or examine any
such documents, instruments, certificates or other papers to determine whether
they are genuine, enforceable, or appropriate for the represented purpose or
whether they have actually been recorded or that they are other than what they
purport to be on their face, or to determine whether any Person executing any
documents is authorized to do so or whether any signature is genuine. If the
Trustee or the Custodian, as its agent, finds any document constituting part of
the Mortgage File not to have been executed or received, or to be unrelated to
the Mortgage Loans identified in Exhibit B or to appear to be defective on its
face, the Trustee or the Custodian, as its agent, shall promptly notify the
Seller. In accordance with the Mortgage Loan Purchase Agreement, the Seller
shall correct or cure any such defect within 90 days from the date of notice
from the Trustee or its custodian of the defect and if the Seller is unable to
cure such defect within such period, and if such defect materially and adversely
affects the interests of the Certificateholders in the related Mortgage


                                      -42-

<PAGE>

Loan, the Trustee shall enforce the Seller's obligation under the Mortgage Loan
Purchase Agreement to purchase such Mortgage Loan at the Purchase Price,
provided, however, that if such defect relates solely to the inability of the
Seller to deliver the original Security Instrument or intervening assignments
thereof, or a certified copy, because the originals of such documents, or a
certified copy, have not been returned by the applicable jurisdiction, the
Seller shall not be required to purchase such Mortgage Loan, if the Seller
delivers such original documents or certified copy promptly upon receipt, but in
no event later than 360 days after the Closing Date.

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

     Section 2.03 Assignment of Interest in the Mortgage Loan Purchase
Agreement.

     (a) The Depositor hereby assigns to the Trustee, on behalf of the
Certificateholders, all of its right, title and interest in the Mortgage Loan
Purchase Agreement, including but not limited to Depositor's rights pursuant to
the Servicing Agreements (noting that the Seller has retained the right in the
event of breach of the representations, warranties and covenants, if any, with
respect to the related Mortgage Loans of the related Servicer under the related
Servicing Agreement to enforce the provisions thereof and to seek all or any
available remedies). The obligations of the Seller to substitute or repurchase,
as applicable, a Mortgage Loan shall be the Trustee's and the
Certificateholders' sole remedy for any breach thereof. At the request of the
Trustee, the Depositor shall take such actions as may be necessary to enforce
the above right, title and interest on behalf of the Trustee and the
Certificateholders or shall execute such further documents as the Trustee may
reasonably require in order to enable the Trustee to carry out such enforcement.
With respect to the representations and warranties described in the Mortgage
Loan Purchase Agreement that are made to the best of the Seller's knowledge, if
it is discovered by any of the Depositor, the Seller, the Master Servicer, the
Securities Administrator or the Trustee that the substance of such
representation and warranty is inaccurate and such inaccuracy materially and
adversely affects the value of the related Mortgage Loan, then notwithstanding
the Seller's lack of knowledge with respect to the substance of such
representation and warranty, such inaccuracy shall be deemed a breach of the
applicable representation or warranty.


                                      -43-

<PAGE>

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

     Section 2.04 Substitution of Mortgage Loans.

     (a) Notwithstanding anything to the contrary in this Agreement, in lieu of
purchasing a Mortgage Loan pursuant to the Mortgage Loan Purchase Agreement or
Sections 2.02 or 2.03 of this Agreement, the Seller may, no later than the date
by which such purchase by the Seller would otherwise be required, tender to the
Trustee or its custodian a Substitute Mortgage Loan accompanied by a certificate
of an authorized officer of the Seller that such Substitute Mortgage Loan
conforms to the requirements set forth in the definition of "Substitute Mortgage
Loan" in the Mortgage Loan Purchase Agreement or this Agreement, as applicable;
provided, however, that substitution pursuant to the Mortgage Loan Purchase
Agreement or Section 2.04 of this Agreement, as applicable, in lieu of purchase
shall not be permitted after the termination of the two-year period beginning on
the Startup Day; provided, further, that if the breach will cause the Mortgage
Loan to be other than a "qualified mortgage" as defined in Section 860G(a)(3) of
the Code, any such cure or substitution must occur within 90 days from the date
the breach is discovered. The Trustee or the Custodian, as its agent, shall
examine the Mortgage File for any


                                      -44-

<PAGE>

Substitute Mortgage Loan in the manner set forth in Section 2.02(a) and the
Trustee or the Custodian, as its agent, shall notify the Seller, in writing,
within five Business Days after receipt, whether the documents relating to the
Substitute Mortgage Loan satisfy the requirements of the third sentence of
Section 2.02(a).

     (b) Within two Business Days after such notification, the Seller shall
provide to the Securities Administrator for deposit in the Distribution Account
the amount, if any, by which the Outstanding Principal Balance as of the next
preceding Due Date of the Mortgage Loan for which substitution is being made,
after giving effect to Scheduled Principal due on such date, exceeds the
Outstanding Principal Balance as of such date of the Substitute Mortgage Loan,
after giving effect to Scheduled Principal due on such date, which amount shall
be treated for the purposes of this Agreement as if it were the payment by the
Seller of the Purchase Price for the purchase of a Mortgage Loan by the Seller.
After such notification to the Seller and, if any such excess exists, upon
written notification of the receipt of such deposit, the Trustee shall accept
such Substitute Mortgage Loan which shall thereafter be deemed to be a Mortgage
Loan hereunder. In the event of such a substitution, accrued interest on the
Substitute Mortgage Loan for the month in which the substitution occurs and any
Principal Prepayments made thereon during such month shall be the property of
the Issuing Entity and accrued interest for such month on the Mortgage Loan for
which the substitution is made and any Principal Prepayments made thereon during
such month shall be the property of the Seller. The Scheduled Principal on a
Substitute Mortgage Loan due on the Due Date in the month of substitution shall
be the property of the Seller and the Scheduled Principal on the Mortgage Loan
for which the substitution is made due on such Due Date shall be the property of
the Issuing Entity.

     (c) Upon acceptance of the Substitute Mortgage Loan (and delivery to the
Trustee or Custodian of a Request for Release for such Mortgage Loan), the
Trustee shall release or cause to be released to the Seller the related Mortgage
File related to any Mortgage Loan released pursuant to the Mortgage Loan
Purchase Agreement or Section 2.04 of this Agreement, as applicable, and shall
execute and deliver all instruments of transfer or assignment, without recourse,
in form as provided to it as are necessary to vest in the Seller title to and
rights under any Mortgage Loan released pursuant to the Mortgage Loan Purchase
Agreement or Section 2.04 of this Agreement, as applicable.

     (d) The Seller shall deliver the documents related to the Substitute
Mortgage Loan in accordance with the provisions of the Mortgage Loan Purchase
Agreement or Sections 2.01(b) and 2.02(b) of this Agreement, as applicable, with
the date of acceptance of the Substitute Mortgage Loan deemed to be the Closing
Date for purposes of the time periods set forth in those Sections. The
representations and warranties set forth in the Mortgage Loan Purchase Agreement
shall be deemed to have been made by the Seller with respect to each Substitute
Mortgage Loan as of the date of acceptance of such Mortgage Loan by the Trustee.
The Master Servicer shall amend the Mortgage Loan Schedule to reflect such
substitution and shall provide a copy of such amended Mortgage Loan Schedule to
the Trustee and the Rating Agencies.

     (e) Notwithstanding any other provision of this Agreement, the right to
substitute Mortgage Loans pursuant to this Article II shall be subject to the
additional limitations that no substitution of a Mortgage Loan shall be made
unless the Securities Administrator and the Trustee shall have received an
Opinion of Counsel (at the expense of the party seeking to make


                                      -45-

<PAGE>

the substitution) that, under current law, such substitution will not (A) affect
adversely the status of any REMIC established hereunder as a REMIC, or of the
related "regular interests" as "regular interests" in any such REMIC, or (B)
cause any such REMIC to engage in a "prohibited transaction" or prohibited
contribution pursuant to the REMIC provisions.

     Section 2.05 Issuance of Certificates. The Trustee acknowledges the
assignment to it on behalf of the Issuing Entity of the Mortgage Loans and the
other assets comprising the Trust Fund and, concurrently therewith, the
Securities Administrator has signed, and countersigned and delivered to the
Depositor, in exchange therefor, Certificates in such authorized denominations
representing such Percentage Interests as the Depositor has requested. The
Trustee agrees that it will hold the Mortgage Loans and such other assets as may
from time to time be delivered to it segregated on the books of the Trustee in
trust for the benefit of the Certificateholders.

     Section 2.06 Representations and Warranties Concerning the Depositor. The
Depositor hereby represents and warrants to the Trustee, the Master Servicer and
the Securities Administrator as follows:

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

          (ii) the Depositor has full corporate power to own its property, to
     carry on its business as presently conducted and to enter into and perform
     its obligations under this Agreement;

          (iii) the execution and delivery by the Depositor of this Agreement
     have been duly authorized by all necessary corporate action on the part of
     the Depositor; and neither the execution and delivery of this Agreement,
     nor the consummation of the transactions herein contemplated, nor
     compliance with the provisions hereof, will conflict with or result in a
     breach of, or constitute a default under, any of the provisions of any law,
     governmental rule, regulation, judgment, decree or order binding on the
     Depositor or its properties or the articles of incorporation or by-laws of
     the Depositor, except those conflicts, breaches or defaults which would not
     reasonably be expected to have a material adverse effect on the Depositor's
     ability to enter into this Agreement and to consummate the transactions
     contemplated hereby;

          (iv) the execution, delivery and performance by the Depositor of this
     Agreement and the consummation of the transactions contemplated hereby do
     not require the consent or approval of, the giving of notice to, the
     registration with, or the taking of any other action in respect of, any
     state, federal or other governmental authority or agency, except those
     consents, approvals, notices, registrations or other actions as have
     already been obtained, given or made;


                                      -46-

<PAGE>

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

          (vi) there are no actions, suits or proceedings pending or, to the
     knowledge of the Depositor, threatened against the Depositor, before or by
     any court, administrative agency, arbitrator or governmental body (i) with
     respect to any of the transactions contemplated by this Agreement or (ii)
     with respect to any other matter which in the judgment of the Depositor
     will be determined adversely to the Depositor and will if determined
     adversely to the Depositor materially and adversely affect the Depositor's
     ability to enter into this Agreement or perform its obligations under this
     Agreement; and the Depositor is not in default with respect to any order of
     any court, administrative agency, arbitrator or governmental body so as to
     materially and adversely affect the transactions contemplated by this
     Agreement; and

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

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

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

          (ii) It has the full corporate power and authority to execute, deliver
     and perform, and to enter into and consummate the transactions contemplated
     by this Agreement and has duly authorized by all necessary corporate action
     on its part the execution, delivery and performance of this Agreement; and
     this Agreement, assuming the due authorization, execution and delivery
     hereof by the other parties hereto, constitutes its legal, valid and
     binding obligation, enforceable against it in accordance with its terms,
     except that (a) the enforceability hereof may be limited by bankruptcy,
     insolvency, moratorium, receivership and other similar laws relating to
     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.


                                      -47-

<PAGE>

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

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

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

                                   ARTICLE III
                 ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

     Section 3.01 Master Servicer. The Master Servicer shall supervise, monitor
and oversee the obligation of the Servicers to service and administer their
respective Mortgage Loans in accordance with the terms of the applicable
Servicing Agreement and shall have full power and authority to do any and all
things which it may deem necessary or desirable in connection with such master
servicing and administration. In performing its obligations hereunder, the
Master Servicer shall act in a manner consistent with Accepted Master Servicing
Practices. Furthermore, the Master Servicer shall oversee and consult with each
Servicer as necessary from time-to-time to carry out the Master Servicer's
obligations hereunder, shall receive, review and evaluate all reports,
information and other data provided to the Master Servicer by each Servicer and
shall cause each Servicer to perform and observe the covenants, obligations and
conditions to be performed or observed by such Servicer under the applicable
Servicing Agreement. The Master Servicer shall independently and separately
monitor each Servicer's servicing activities with respect to each related
Mortgage Loan, reconcile the results of such monitoring with such information
provided in the previous sentence on a monthly basis and coordinate corrective
adjustments to the Servicers' and Master Servicer's records, and based on such
reconciled and corrected information, the Master Servicer shall provide such
information to the Securities Administrator as shall be necessary in order for
it to prepare the statements specified in Section 6.04, and prepare any other
information and statements required to be forwarded by the Master Servicer
hereunder. The Master Servicer shall reconcile the results of its monitoring
with the


                                      -48-

<PAGE>

actual remittances of the Servicers to the Master Servicer Collection Account
pursuant to the applicable Servicing Agreements.

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

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

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

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

     Section 3.02 REMIC-Related Covenants. For as long as each REMIC shall
exist, the Trustee and the Securities Administrator shall act in accordance
herewith to assure continuing treatment of such REMIC as a REMIC, and the
Trustee and the Securities Administrator shall comply with any directions of the
Depositor, the related Servicer or the Master Servicer to assure such continuing
treatment. In particular, the Trustee shall not (a) sell or permit the sale of
all or any portion of the Mortgage Loans or of any investment of deposits in an
Account unless such sale is as a result of a repurchase of the Mortgage Loans
pursuant to this Agreement or the Trustee has received a REMIC Opinion prepared
at the expense of the Issuing Entity; and (b) other than with respect to a
substitution pursuant to the Mortgage Loan Purchase Agreement or Section 2.04 of
this Agreement, as applicable, accept any contribution to any REMIC after the
Startup Day without receipt of a REMIC Opinion.

     Section 3.03 Monitoring of Servicers.

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

     (b) The Master Servicer, for the benefit of the Trustee and the
Certificateholders, shall enforce the obligations of each Servicer under the
related Servicing Agreement, and shall, in the event that a Servicer fails to
perform its obligations in accordance with the related Servicing Agreement,
subject to the preceding paragraph, terminate the rights and obligations of such
Servicer thereunder and act as servicer of the related Mortgage Loans or, if the
Master Servicer is unwilling or unable to act as a Servicer, the Master Servicer
shall cause the Trustee to enter in to a new Servicing Agreement with a
successor Servicer selected by the Master Servicer that is eligible in
accordance with the criteria specified in this Agreement; provided, however, it
is understood and acknowledged by the parties hereto that there will be a period
of transition (not to exceed 90 days) before the actual servicing functions can
be fully transferred to such successor servicer. In either event, such
enforcement, including, without limitation, the legal prosecution of claims,
termination of the Servicing Agreements and the pursuit of other appropriate
remedies, shall be in such form and carried out to such an extent and at such
time as the Master Servicer, in its good faith business judgment, would require
were it the owner of the related Mortgage Loans. The Master Servicer shall pay
the costs of such enforcement at its own expense subject to Section 3.03(c),
provided that the Master Servicer shall not be required to prosecute or defend
any legal action except to the extent that the Master Servicer shall have
received reasonable indemnity for its costs and expenses in pursuing such
action.

     (c) To the extent that the costs and expenses of the Master Servicer
related to any termination of a Servicer, appointment of a successor Servicer or
the transfer and assumption of servicing by the Master Servicer with respect to
any Servicing Agreement (including, without


                                      -50-

<PAGE>

limitation, (i) all legal costs and expenses and all due diligence costs and
expenses associated with an evaluation of the potential termination of a
Servicer as a result of an event of default by such Servicer and (ii) all costs
and expenses associated with the complete transfer of servicing, including all
servicing files and all servicing data and the completion, correction or
manipulation of such servicing data as may be required by the successor servicer
to correct any errors or insufficiencies in the servicing data or otherwise to
enable the successor service to service the Mortgage Loans in accordance with
the related Servicing Agreement) are not fully and timely reimbursed by the
terminated Servicer, the Master Servicer shall be entitled to reimbursement of
such costs and expenses from the Master Servicer Collection Account pursuant to
Section 4.03(b).

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

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

     Section 3.04 Fidelity Bond. The Master Servicer, at its expense, shall
maintain in effect a blanket fidelity bond and an errors and omissions insurance
policy, affording coverage with respect to all directors, officers, employees
and other Persons acting on such Master Servicer's behalf, and covering errors
and omissions in the performance of the Master Servicer's obligations hereunder.
The errors and omissions insurance policy and the fidelity bond shall be in such
form and amount generally acceptable for entities serving as master servicers or
trustees.

     Section 3.05 Power to Act; Procedures. The Master Servicer shall master
service the Mortgage Loans and shall have full power and authority, subject to
the REMIC Provisions and the provisions of Article X hereof, to do any and all
things that it may deem necessary or desirable in connection with the master
servicing and administration of the Mortgage Loans, including but not limited to
the power and authority (i) to execute and deliver, on behalf of the
Certificateholders and the Trustee, customary consents or waivers and other
instruments and documents, (ii) to consent to transfers of any Mortgaged
Property and assumptions of the Mortgage Notes and related Mortgages, (iii) to
collect any Insurance Proceeds and Liquidation Proceeds, and (iv) to effectuate
foreclosure or other conversion of the ownership of the Mortgaged Property
securing any Mortgage Loan, in each case, in accordance with the provisions of
this Agreement and the related Servicing Agreement, as applicable; provided,
however, that the Master Servicer shall not (and, consistent with its
responsibilities under Section 3.03, shall not permit any Servicer to) knowingly
or intentionally take any action, or fail to take (or fail to cause to be taken)
any action reasonably within its control and the scope of duties more
specifically set forth herein, that, under the REMIC Provisions, if taken or not
taken, as the case may be, would cause any REMIC created hereunder to fail to
qualify as a REMIC or result in the imposition of a tax upon the Issuing Entity
(including but not limited to the tax on prohibited transactions as defined in
Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth
in Section 860G(d) of the Code) unless the Master Servicer has received an
Opinion of Counsel (but not at the expense of the Master Servicer) to the effect
that the contemplated action will not would cause any REMIC created hereunder to
fail to qualify as a REMIC or result in the imposition of a tax upon any REMIC
created hereunder. The Trustee shall furnish the Master Servicer, upon written
request from a Servicing Officer, with any limited


                                      -51-

<PAGE>

powers of attorney (in form acceptable to the Trustee) empowering the Master
Servicer or any Servicer to execute and deliver instruments of satisfaction or
cancellation, or of partial or full release or discharge, and to foreclose upon
or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in
any court action relating to the Mortgage Loans or the Mortgaged Property, in
accordance with the applicable Servicing Agreement and this Agreement, and the
Trustee shall execute and deliver such other documents, as the Master Servicer
may request, to enable the Master Servicer to master service and administer the
Mortgage Loans and carry out its duties hereunder, in each case in accordance
with Accepted Master Servicing Practices (and the Trustee shall have no
liability for misuse of any such powers of attorney by the Master Servicer or
any Servicer). If the Master Servicer or the Trustee has been advised that it is
likely that the laws of the state in which action is to be taken prohibit such
action if taken in the name of the Trustee or that the Trustee would be
adversely affected under the "doing business" or tax laws of such state if such
action is taken in its name, the Master Servicer shall join with the Trustee in
the appointment of a co-trustee pursuant to Section 9.11 hereof. In the
performance of its duties hereunder, the Master Servicer shall be an independent
contractor and shall not, except in those instances where it is taking action in
the name of the Trustee, be deemed to be the agent of the Trustee.

     Section 3.06 Due-on-Sale Clauses; Assumption Agreements. To the extent
provided in the applicable Servicing Agreement, to the extent Mortgage Loans
contain enforceable due-on-sale clauses, the Master Servicer shall cause the
Servicers to enforce such clauses in accordance with the applicable Servicing
Agreement. If applicable law prohibits the enforcement of a due-on-sale clause
or such clause is otherwise not enforced in accordance with the applicable
Servicing Agreement, and, as a consequence, a Mortgage Loan is assumed, the
original Mortgagor may be released from liability in accordance with the
applicable Servicing Agreement.

     Section 3.07 Release of Mortgage Files.

     (a) Upon becoming aware of the payment in full of any Mortgage Loan, or the
receipt by any Servicer of a notification that payment in full has been escrowed
in a manner customary for such purposes for payment to Certificateholders on the
next Distribution Date, the Servicers or the Master Servicer will, if required
under the applicable Servicing Agreement, promptly furnish to the Custodian, on
behalf of the Trustee, two copies of a certification substantially in the form
of Exhibit D hereto signed by a Servicing Officer or in a mutually agreeable
electronic format which will, in lieu of a signature on its face, originate from
a Servicing Officer (which certification shall include a statement to the effect
that all amounts received in connection with such payment that are required to
be deposited in the Protected Account maintained by the applicable Servicer
pursuant to its Servicing Agreement have been or will be so deposited) and shall
request that the Custodian, on behalf of the Trustee, deliver to the applicable
Servicer the related Mortgage File. Upon receipt of such certification and
request, the Custodian, on behalf of the Trustee, shall no later than five
Business Days (or, to the extent that the applicable Servicer notifies the
Seller that a document is not in the Servicer's possession as part of the
Servicing File which is needed for purposes of the Servicer complying with any
applicable law, within such shorter period as may be necessary to enable the
Servicer to comply with such law), release the related Mortgage File to the
applicable Servicer and the Trustee and Custodian shall have no further
responsibility with regard to such Mortgage File. Upon any such payment in full,
each


                                      -52-

<PAGE>

Servicer is authorized, to give, as agent for the Trustee, as the mortgagee
under the Mortgage that secured the Mortgage Loan, an instrument of satisfaction
(or assignment of mortgage without recourse) regarding the Mortgaged Property
subject to the Mortgage, which instrument of satisfaction or assignment, as the
case may be, shall be delivered to the Person or Persons entitled thereto
against receipt therefor of such payment, it being understood and agreed that no
expenses incurred in connection with such instrument of satisfaction or
assignment, as the case may be, shall be chargeable to the Protected Account.

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

     Section 3.08 Documents, Records and Funds in Possession of Master Servicer
To Be Held for Trustee.

     (a) The Master Servicer shall transmit and each Servicer (to the extent
required by the related Servicing Agreement) shall transmit to the Trustee or
Custodian such documents and instruments coming into the possession of the
Master Servicer or such Servicer from time to time as are required by the terms
hereof, or in the case of the Servicers, the applicable Servicing Agreement, to
be delivered to the Trustee or Custodian. Any funds received by the Master
Servicer or by a Servicer in respect of any Mortgage Loan or which otherwise are
collected by the Master Servicer or by a Servicer as Liquidation Proceeds or
Insurance Proceeds in respect of any Mortgage Loan shall be held for the benefit
of the Trustee and the Certificateholders subject to the Master Servicer's right
to retain or withdraw from the Master Servicer Collection Account the Master
Servicing Compensation and other amounts provided in this Agreement, and to the
right of each Servicer to retain its Servicing Fee and other amounts as provided
in the applicable Servicing Agreement. The Master Servicer shall, and (to the
extent provided in the applicable Servicing Agreement) shall cause each Servicer
to, provide access to information and documentation regarding the Mortgage Loans
to the Trustee, its agents and accountants at any time upon reasonable request
and during normal business hours, and to Certificateholders that are savings and
loan associations, banks or insurance companies, the Office of Thrift
Supervision, the FDIC and the supervisory agents and examiners of such Office
and Corporation or examiners of any other federal or state banking or insurance
regulatory authority if so required by applicable regulations of the Office of
Thrift Supervision or other regulatory authority, such access to be afforded
without charge but only upon reasonable request in writing and during


                                      -53-

<PAGE>

normal business hours at the offices of the Master Servicer designated by it. In
fulfilling such a request, the Master Servicer shall not be responsible for
determining the sufficiency of such information.

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

     Section 3.09 Standard Hazard Insurance and Flood Insurance Policies.

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

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

     Section 3.10 Presentment of Claims and Collection of Proceeds. The Master
Servicer shall (to the extent provided in the applicable Servicing Agreement)
cause the related Servicer to, prepare and present on behalf of the Trustee and
the Certificateholders all claims under the Insurance Policies and take such
actions (including the negotiation, settlement, compromise or enforcement of the
insured's claim) as shall be necessary to realize recovery under such policies.
Any proceeds disbursed to the Master Servicer (or disbursed to a Servicer and
remitted to the Master Servicer) in respect of such policies, bonds or contracts
shall be promptly deposited in the Master Servicer Collection Account upon
receipt, except that any amounts realized that are to be applied to the repair
or restoration of the related Mortgaged Property as a condition precedent to


                                      -54-

<PAGE>

the presentation of claims on the related Mortgage Loan to the insurer under any
applicable Insurance Policy need not be so deposited (or remitted).

     Section 3.11 Maintenance of the Primary Mortgage Insurance Policies.

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

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

     Section 3.12 Trustee to Retain Possession of Certain Insurance Policies and
Documents. The Trustee or the Custodian shall retain possession and custody of
the originals (to the extent available) of any Primary Mortgage Insurance
Policies, or certificate of insurance if applicable, and any certificates of
renewal as to the foregoing as may be issued from time to time as contemplated
by this Agreement. Until all amounts distributable in respect of the
Certificates have been distributed in full and the Master Servicer otherwise has
fulfilled its obligations under this Agreement, the Trustee or its Custodian
shall also retain possession and custody of each Mortgage File in accordance
with and subject to the terms and conditions of this Agreement. The Master
Servicer shall promptly deliver or cause to be delivered to the Trustee or the
Custodian upon the execution or receipt thereof the originals of any Primary
Mortgage Insurance Policies, any certificates of renewal, and such other
documents or instruments that constitute portions of the Mortgage File that come
into the possession of the Master Servicer from time to time.

     Section 3.13 Realization Upon Defaulted Mortgage Loans. The Master Servicer
shall cause each Servicer (to the extent required under the related Servicing
Agreement) to foreclose upon, repossess or otherwise comparably convert the
ownership of Mortgaged Properties securing such of the Mortgage Loans as come
into and continue in default and as to which no


                                      -55-

<PAGE>

satisfactory arrangements can be made for collection of delinquent payments, all
in accordance with the terms and conditions of the applicable Servicing
Agreement.

     Section 3.14 Compensation for the Master Servicer. The Master Servicer will
be entitled to all income and gain realized from any investment of funds in the
Master Servicer Collection Account, pursuant to Article IV, for the performance
of its activities hereunder. Servicing compensation in the form of assumption
fees, if any, late payment charges, as collected, if any, or otherwise (but not
including any prepayment premium or penalty) shall be retained by the applicable
Servicer and shall not be deposited in the Protected Account. The Master
Servicer shall be required to pay all expenses incurred by it in connection with
its activities hereunder and shall not be entitled to reimbursement therefor
except as provided in this Agreement.

     Section 3.15 REO Property.

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

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

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

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

Agreement, or any other applicable agreement, as the case may be, such party
shall provide, an assessment of compliance pursuant to this Section 3.17,

agreement notwithstanding any such termination, assignment or resignation.

     (b) Not later than March 1 of each calendar year (other than the calendar

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

     By March 1 (with a ten-calendar day cure period) of each year, commencing
in March 2008, the Master Servicer, the Securities Administrator and the
Custodian, each at its own expense, shall cause, and each such party shall cause
any Servicing Function Participant engaged by it to cause, each at its own

services to the Master Servicer, the Securities Administrator, or such other
Servicing Function Participants, as the case may be) and that is a member of the

conducted by such firm in accordance with standards for attestation engagements
issued or adopted by the Public Company Accounting Oversight Board, it is
expressing an opinion as to whether such party's compliance with the Relevant
Servicing Criteria was fairly stated in all material respects, or it cannot
express an overall opinion regarding such party's assessment of compliance with
the Relevant Servicing Criteria. In the event that an overall opinion cannot be
expressed, such registered public accounting firm shall state in such report why
it was unable to express such an opinion. Such report must be available for
general use and not contain restricted use language.

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

     The Master Servicer shall include each such attestation furnished to it by
the Servicers with its own attestation to be submitted to the Securities
Administrator pursuant to this Section.

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

     Section 3.18 Periodic Filings.

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

     (b) For so long as the Issuing Entity is subject to the reporting
requirements of the Exchange Act, following the occurrence of a Reportable Event
(A) each party listed on Exhibit Q-3 hereto shall use commercially reasonable
best efforts to provide immediate notice to the Master Servicer, the Securities
Administrator and the Depositor, by fax and by phone or by e-mail and by phone,
(B) each such party shall be required to provide to the Securities Administrator
and the Depositor, to the extent known, in EDGAR-compatible format or in such
other format as agreed upon by the Securities Administrator and such party, the
form and substance of any Form 8-K Disclosure Information if applicable,
together with the form set forth


                                      -60-

<PAGE>

on Exhibit O (the "Additional Disclosure Notification") by the close of business
New York City time on the 2nd Business Day following the occurrence of such
Reportable Event and (C) the Depositor, shall approve, as to form and substance,
or disapprove, as the case may be, the inclusion of the Form 8-K Disclosure
Information on Form 8-K. The Securities Administrator has no duty under this
Agreement to monitor or enforce the performance by the parties listed on Exhibit
Q-3 of their duties under this paragraph or proactively solicit or procure from
such parties any Form 8-K Disclosure Information. The Depositor will be
responsible for any reasonable fees and expenses assessed or incurred by the
Securities Administrator in connection with including any Form 8-K Disclosure
Information on Form 8-K pursuant to this paragraph.

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

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

     (e) Within fifteen (15) days after each Distribution Date (subject to
permitted extensions under the Exchange Act), the Securities Administrator
shall, on behalf of the Issuing Entity and in accordance with industry
standards, prepare and file with the Commission via the Electronic Data
Gathering and Retrieval System (EDGAR), a Form 10-D with a copy of the Monthly
Statement for such Distribution Date as an exhibit thereto. Any disclosure in
addition


                                      -61-

<PAGE>

to the Monthly Statement that is required to be included on Form 10-D
("Additional Form 10-D Disclosure") shall be reported by the parties set forth
on Exhibit Q-1 to the Depositor and the Securities Administrator and directed
and approved by the Depositor pursuant to the following paragraph, and the
Securities Administrator will have no duty or liability for any failure
hereunder to determine or prepare any Additional Form 10-D Disclosure except as
set forth in the next paragraph.

     (f) As set forth in Exhibit Q-1 hereto, for so long as the Issuing Entity
is subject to the reporting requirements of the Exchange Act, within five (5)
calendar days after the related Distribution Date (i) each party listed on
Exhibit Q-1 hereto shall be required to provide to the Depositor and the
Securities Administrator, to the extent known, in EDGAR-compatible format or in
such other format as agreed upon by the Securities Administrator and such party,
the form and substance of any Additional Form 10-D Disclosure if applicable
together with an Additional Disclosure Notification, and (ii) the Depositor will
approve, as to form and substance, or disapprove, as the case may be, the
inclusion of the Additional Form 10-D Disclosure on Form 10-D. The Securities
Administrator has no duty under this Agreement to monitor or enforce the
performance by the parties listed on Exhibit Q-1 of their duties under this
paragraph or proactively solicit or procure from such parties any Additional
Form 10-D Disclosure Information. The Depositor will be responsible for any
reasonable fees and expenses incurred by the Securities Administrator in
connection with including any Additional Form 10-D Disclosure on Form 10-D
pursuant to this paragraph.

     (g) After preparing the Form 10-D, the Securities Administrator shall, upon
request, forward electronically a copy of the Form 10-D to the Depositor
(provided that such Form 10-D includes any Additional Form 10-D Disclosure).
Within two Business Days after receipt of such copy, but no later than the 12th
calendar day after the Distribution Date, the Depositor shall notify the
Securities Administrator in writing (which may be furnished electronically) of
any changes to or approval of such Form 10-D. In the absence of receipt of any
written changes or approval, or if the Depositor does not request a copy of a
Form 10-D, the Securities Administrator shall be entitled to assume that such
Form 10-D is in final form and the Securities Administrator may proceed with the
process for execution and filing of the Form 10-D. A duly authorized
representative of the Master Servicer shall sign each Form 10-D. If a Form 10-D
cannot be filed on time or if a previously filed Form 10-D needs to be amended,
the Securities Administrator will follow the procedures set forth in Section
3.18(n). Promptly (but not later than one Business Day) after filing with the
Commission, the Securities Administrator will make available on its internet
website a final executed copy of each Form 10-D prepared and filed by the
Securities Administrator. Form 10-D requires the registrant to indicate (by
checking "yes" or "no") that it "(1) has filed all reports required to be filed
by Section 13 or 15(d) of the Exchange Act during the preceding 12 months (or
for such shorter period that the registrant was required to file such reports),
and (2) has been subject to such filing requirements for the past 90 days." The
Depositor hereby instructs the Securities Administrator, with respect to each
Form 10-D, to check "yes" for each item unless the Securities Administrator has
received timely prior written notice from the Depositor that the answer should
be "no" for an item. The parties to this Agreement acknowledge that the
performance by the Master Servicer and the Securities Administrator of its
respective duties under this Section 3.18 related to the timely preparation,
execution and filing of Form 10-D is contingent upon the other parties hereto
strictly observing all applicable deadlines in the performance of their duties
under this Section 3.18. The Depositor


                                      -62-

<PAGE>

acknowledges that the performance by the Master Servicer and the Securities
Administrator of its duties under this Section 3.18 related to the timely
preparation, execution and filing of Form 10-D is also contingent upon the
Servicers, the Custodian and any Servicing Function Participant strictly
observing deadlines no later than those set forth in this paragraph that are
applicable to the parties to this Agreement in the delivery to the Securities
Administrator of any necessary Additional Form 10-D Disclosure pursuant to the
related Servicing Agreements, the Custodial Agreement or any other applicable
agreement. Neither the Master Servicer nor the Securities Administrator will
have any liability for any loss, expense, damage or claim arising out of or with
respect to any failure to properly prepare, execute and/or timely file such Form
10-D resulting from the Securities Administrator's inability or failure to
obtain or receive any information needed to prepare, arrange for execution or
file such Form 10-D on a timely basis.

     (h) On or prior to the 90th calendar day after the end of the fiscal year
for the Issuing Entity or such earlier date as may be required by the Exchange
Act (the "10-K Filing Deadline") (it being understood that the fiscal year for
the Issuing Entity ends on December 31st of each year) commencing in March 2008,
the Securities Administrator shall, on behalf of the Issuing Entity and in
accordance with industry standards, prepare and file with the Commission via
EDGAR a Form 10-K with respect to the Issuing Entity. Such Form 10-K shall
include the following items, in each case, as applicable, to the extent they
have been delivered to the Securities Administrator within the applicable time
frames set forth in this Agreement, the related Servicing Agreements and
Custodial Agreement: (i) an annual compliance statement for the Master Servicer,
each Servicer, the Securities Administrator and any Servicing Function
Participant engaged by any such party (together with the Custodian, each a
"Reporting Servicer"), as described in Section 3.16 of this Agreement, the
related Servicing Agreement and the Custodial Agreement; provided, however, that
the Securities Administrator, at its discretion, may omit from the Form 10-K any
annual compliance statement that is not required to be filed with such Form 10-K
pursuant to Regulation AB; (ii)(A) the annual reports on assessment of
compliance with Servicing Criteria for each Reporting Servicer (unless the
Depositor has determined that such compliance statement is not required by
Regulation AB), as described in Section 3.17 of this Agreement, the related
Servicing Agreement and the Custodial Agreement, and (B) if any Reporting
Servicer's report on assessment of compliance with Servicing Criteria described
in Section 3.17 identifies any material instance of noncompliance, disclosure
identifying such instance of noncompliance, or if any Reporting Servicer's
report on assessment of compliance with Servicing Criteria described in Section
3.17 of this Agreement is not included as an exhibit to such Form 10-K,
disclosure that such report is not included and an explanation why such report
is not included; provided, however, that the Securities Administrator, at its
discretion, may omit from the Form 10-K any assessment of compliance or
attestation report described in clause (iii) below that is not required to be
filed with such Form 10-K pursuant to Regulation AB; (iii)(A) the registered
public accounting firm attestation report for each Reporting Servicer, as
described in Section 3.17 of this Agreement, the related Servicing Agreement and
the Custodial Agreement, and (B) if any registered public accounting firm
attestation report described under Section 3.17 of this Agreement identifies any
material instance of noncompliance, disclosure identifying such instance of
noncompliance, or if any such registered public accounting firm attestation
report is not included as an exhibit to such Form 10-K, disclosure that such
report is not included and an explanation why such report is not included, and
(iv) a Sarbanes-Oxley Certification in the form attached hereto as Exhibit L,

disclosure or information in


                                      -63-

<PAGE>

addition to (i) through (iv) above that is required to be included on Form 10-K
("Additional Form 10-K Disclosure") shall be reported by the parties as set
forth in Exhibit Q-2 to the Depositor and the Securities Administrator and
directed and approved by the Depositor pursuant to the following paragraph and
the Securities Administrator will have no duty or liability for any failure
hereunder to determine or prepare any Additional Form 10-K Disclosure except or
set forth in the next paragraph.

     (i) As set forth in Exhibit Q-2 hereto, no later than March 1 (with a ten
calendar day cure period) of each year that the Issuing Entity is subject to the
Exchange Act reporting requirements, commencing in March 2008, (i) the parties
listed on Exhibit Q-2 hereto shall be required to provide to the Depositor and
the Securities Administrator, to the extent known, in EDGAR-compatible format or
in such other format as agreed upon by the Securities Administrator and such
party, the form and substance of any Additional Form 10-K Disclosure, if
applicable together with an Additional Disclosure Notification, and (ii) the
Depositor will approve, as to form and substance, or disapprove, as the case may
be, the inclusion of the Additional Form 10-K Disclosure. The Securities
Administrator has no duty under this Agreement to monitor or enforce the
performance by the parties listed on Exhibit Q-2 of their duties under this
paragraph or proactively solicit or procure from such parties any Additional
Form 10-K Disclosure Information. The Depositor will be responsible for any
reasonable fees and expenses incurred by the Securities Administrator in
connection with including any Additional Form 10-K Disclosure on Form 10-K
pursuant to this paragraph.

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


                                      -64-
<PAGE>

Master Servicer and the Securities Administrator of its duties under this
Section 3.18 related to the timely preparation, execution and filing of Form
10-K is also contingent upon the Servicers, the Custodian and any Servicing
Function Participant strictly observing deadlines no later than those set forth
in this paragraph that are applicable to the parties to this Agreement in the
delivery to the Securities Administrator of any necessary Additional Form 10-K
Disclosure, any annual statement of compliance and any assessment of compliance
and attestation pursuant to the related Servicing Agreement, the Custodial
Agreement or any other applicable agreement. Neither the Master Servicer nor the
Securities Administrator shall have any liability for any loss, expense, damage
or claim arising out of or with respect to any failure to properly prepare,
execute and/or timely file such Form 10-K resulting from the Securities
Administrator's inability or failure to obtain or receive any information from
any other party hereto or any Servicer, Custodian or Servicing Function
Participant needed to prepare, execute or file such Form 10-K.

     (k) Each Form 10-K shall include a Sarbanes-Oxley Certification, which
shall be in the form attached hereto as Exhibit L. Each Servicer shall sign and
provide, and each of the Servicers, the Master Servicer and the Securities
Administrator shall cause any Servicing Function Participant engaged by it to
sign and provide, to the person who signs the Sarbanes-Oxley Certification (the
"Certifying Person") by March 1 (with a ten day cure period) of each year in
which the Issuing Entity is subject to the reporting requirements of the
Exchange Act and otherwise within a reasonable period of time upon request, a
certification (a "Back-Up Certification") (in the form attached hereto as
Exhibit M) upon which the Certifying Person, the entity for which the Certifying
Person acts as an officer and such entity's officers, directors and affiliates
(collectively, with the Certifying Person, the "Certification Parties") can
reasonably rely. The senior officer of the Master Servicer in charge of the
master servicing function shall serve as the Certifying Person on behalf of the
Issuing Entity. Such officer of the Certifying Person can be contacted by e-mail
at cts.sec.notifications@wellsfargo.com or by facsimile at 443-367-3307. In the
event any such party or Servicing Function Participant engaged by any such party
is terminated or resigns pursuant to the terms of this Agreement, or any other
applicable agreement, as the case may be, such party shall provide a Back-Up
Certification to the Master Servicer pursuant to this Section 3.18 with respect
to the period of time it was subject to this Agreement or any other applicable
agreement, as the case may be. Notwithstanding the foregoing, (i) the Master
Servicer and the Securities Administrator shall not be required to deliver a
Back-Up Certification to each other if both are the same Person and the Master
Servicer is the Certifying Person and (ii) the Master Servicer shall not be
obligated to sign the Sarbanes-Oxley Certification in the event that it does not
receive any Back-Up Certification required to be furnished to it pursuant to
this section or any Servicing Agreement or Custodial Agreement.

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

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


                                      -65-

     (n) In the event that the Securities Administrator is unable to timely file
with the Commission all or any required portion of any Form 8-K, 10-D or 10-K
required to be filed by this Agreement because required disclosure information
was either not delivered to it or delivered to it after the delivery deadlines
set forth in this Agreement or for any other reason, the Securities
Administrator will promptly notify electronically the Depositor of such
inability to make a timely filing with the Commission. In the case of Form 10-D
and 10-K, the parties to this Agreement will cooperate to prepare and file a
Form 12b-25 and a 10-D/A and 10K/A, as applicable, pursuant to Rule 12b-25 of
the Exchange Act. In the case of Form 8-K, the Securities Administrator will,
upon receipt of all required Form 8-K Disclosure Information and upon the
approval and direction of the Depositor, include such disclosure information on
the next succeeding Form 10-D to be filed for the Issuing Entity. In the event
that any previously filed Form 8-K, 10-D or 10-K needs to be amended, in
connection with any Additional Form 10-D Disclosure (other than, in the case of
Form 10-D, for the purpose of restating any Monthly Statement), Additional Form
10-K Disclosure or Form 8-K Disclosure Information, the Securities Administrator
will electronically notify the Depositor and such other parties to the
transaction as are affected by such amendment, and such parties will cooperate
to prepare any necessary 8-K/A, 10-D/A or 10-K/A. Any Form 15, Form 12b-25 or
any amendment to Form 8-K, 10-D or 10-K shall be signed by duly authorized
representative or a senior officer in charge of master servicing, as applicable,
of the Master Servicer. The parties to this Agreement acknowledge that the
performance by the Master Servicer of its duties under this Section 3.18 related
to the timely preparation, execution and filing of Form 15, a Form 12b-25 or any
amendment to Form 8-K, 10-D or 10-K is contingent upon each such party
performing its duties under this Section. Neither the Master Servicer nor the
Securities Administrator shall have any liability for any loss, expense, damage
or claim arising out of or with respect to any failure to properly prepare,
execute and/or timely file any such Form 15, Form 12b-25 or any amendments to
Forms 8-K, 10-D or 10-K, where such failure results from the Securities
Administrator's inability or failure to receive, on a timely basis, any
information from any other party hereto or any Servicer, any Custodian or any
Servicing Function Participant needed to prepare, arrange for execution or file
such Form 15, Form 12b-25 or any amendments to Forms 8-K, 10-D or 10-K.

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

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

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

     Section 3.19 Compliance with Regulation AB. Each of the parties hereto
acknowledges and agrees that the purpose of Sections 3.16, 3.17 and 3.18 is to
facilitate compliance by the Depositor with the provisions of Regulation AB, as
such may be amended or


                                      -66-

<PAGE>

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

     Section 3.20 Servicing Rights Owner. At the Servicing Rights Owner's
request, HLS or Wilshire, as applicable, shall resign as Servicer with respect
to those Mortgage Loans it is servicing hereunder upon the selection and
appointment of a successor servicer by the Servicing Rights Owner; provided that
the Servicing Rights Owner delivers to the Master Servicer, the Trustee, the
Securities Administrator and HLS or Wilshire, as applicable, a letter indicating
that such successor servicer designated by the Servicing Rights Owner either (x)
meets the eligibility requirements for a successor servicer, including that such
successor servicer is a Qualified Servicer or (y) is a servicer acceptable to
the Rating Agencies as evidenced by a letter from each Rating Agency that the
appointment of such successor servicer shall not cause a downgrade of any class
of Certificate. No appointment of a successor servicer hereunder shall be
effective until the Master Servicer shall have consented thereto (such consent
not to be unreasonably withheld). Upon such appointment, at the date specified
in such letter such successor servicer will become a servicer pursuant to the
terms of this Agreement. Any successor servicer shall be an institution that is
a Fannie Mae and Freddie Mac approved seller/servicer in good standing, shall be
willing to service the Mortgage Loans and shall accept such delegation and
assignment, and shall service the Mortgage Loans pursuant to a servicing
agreement entered into among the successor servicer, the Depositor and the
Master Servicer, provided that such servicing agreement shall prohibit the
successor servicer from causing any Adverse REMIC Event.

                                   ARTICLE IV
                                    ACCOUNTS

     Section 4.01 Protected Accounts.

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

<PAGE>

Designated Depository Institution and segregated on the books of such
institution in the name of the Trustee for the benefit of Certificateholders.

     (b) To the extent provided in the related Servicing Agreement, amounts on
deposit in a Protected Account may be invested in Permitted Investments in the
name of the Trustee for the benefit of Certificateholders and, except as
provided in the preceding paragraph, not commingled with any other funds, such
Permitted Investments to mature, or to be subject to redemption or withdrawal,

Servicing Agreement) shall deposit the amount of any such loss in the Protected
Account within two Business Days of receipt of notification of such loss but not
later than the second Business Day prior to the Distribution Date on which the
moneys so invested are required to be distributed to the Certificateholders.

     (c) To the extent provided in the related Servicing Agreement and subject
to this Article IV, on or before each Servicer Remittance Date, the related

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

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

          (ii) Principal Prepayments in Full and any Liquidation Proceeds
     received by such Servicer with respect to such Mortgage Loans in the
     related Prepayment Period, with interest to the date of prepayment or
     liquidation, net of the amount thereof comprising the Servicing Fees;

          (iii) Curtailments received by such Servicer for such Mortgage Loans

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

     (d) Withdrawals by the Master Servicer may be made from an Account only to
make remittances as provided in Section 4.01(c), 4.02 and 4.03; to reimburse the
Master Servicer or a Servicer for Monthly Advances which have been recovered by
subsequent collection from the related Mortgagor; to remove amounts deposited in
error; to remove fees, charges or other such amounts deposited on a temporary
basis; or to clear and terminate the account at the termination of this
Agreement in accordance with Section 10.01. As provided in Sections 4.01(c) and

certain amounts otherwise due to the Servicers may be retained by them as set
forth in the related Servicing Agreements and need not be deposited in the

     (a) The Master Servicer shall establish and maintain in the name of the
Trustee, for the benefit of the Certificateholders, the Master Servicer

following amounts:

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

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

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

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

statement account or payoff, substitution, satisfaction, release and other like
fees and charges and (ii) the items enumerated in Sections 4.05(a)(i), (ii),

related Servicer to the Distribution Account or the Master Servicer Collection
Account, as applicable. In the event that the Master Servicer shall deposit or
cause to be deposited to the Distribution Account any amount not required to be
credited thereto, the Securities Administrator, upon receipt of a written
request therefor signed by a Servicing Officer of the Master Servicer, shall
promptly transfer such amount to the Master Servicer from the Distribution
Account, any provision herein to the contrary notwithstanding.


                                      -69-

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

     Section 4.03 Permitted Withdrawals and Transfers from the Master Servicer
Collection Account.

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

     (b) On an ongoing basis, the Master Servicer shall withdraw from the Master
Servicer Collection Account (i) any expenses recoverable by the Trustee, the
Master Servicer or the Securities Administrator pursuant to this Agreement,
including but not limited to Sections 2.01(b), 3.03, 7.04 and 9.05 and (ii) any
amounts payable to the Master Servicer as set forth in Section 3.14.

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

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

     Section 4.04 Distribution Account.

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

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

     (c) The Distribution Account shall constitute a trust account of the Trust
Fund segregated on the books of the Securities Administrator and held by the
Securities Administrator in trust in its Corporate Trust Office, and the
Distribution Account and the funds deposited therein shall not be subject to,
and shall be protected to the maximum extent permitted by applicable law from,
all claims, liens, and encumbrances of any creditors or depositors of the
Securities Administrator, the Trustee or the Master Servicer (whether made
directly, or indirectly through a liquidator or receiver of the Securities
Administrator, the Trustee or the Master Servicer). The Distribution Account
shall be an Eligible Account. The amount at any time credited to the
Distribution Account shall be (i) fully insured by the FDIC to the maximum
coverage provided thereby or (ii) invested in the name of the Trustee, in such
Permitted Investments selected by the Master Servicer or deposited in demand
deposits with such depository institutions as selected by the Master Servicer,
provided that time deposits of such depository institutions would be a Permitted
Investment. All Permitted Investments shall mature or be subject to redemption
or withdrawal on or before, and shall be held until, the next succeeding
Distribution Date if the obligor for such Permitted Investment is the Master
Servicer or, if such obligor is any other Person, the Business Day preceding
such Distribution Date. All investment earnings on amounts on deposit in the
Distribution Account or benefit from funds uninvested therein from time to time
shall be for the account of the Securities Administrator. The Securities
Administrator shall be permitted to withdraw or receive distribution of any and
all investment earnings from the Distribution Account on each Distribution Date.
If there is any loss on a Permitted Investment or demand deposit, the Securities
Administrator shall deposit such amount in the Distribution Account. With
respect to the Distribution Account and the funds deposited therein, the
Securities Administrator shall take such action as may be necessary to ensure
that the Certificateholders shall be entitled to the priorities afforded to such
a trust account (in addition to a claim against the estate of the Trust) as
provided by 12 U.S.C. Section 92a(e), and applicable regulations pursuant
thereto, if applicable, or any applicable comparable state statute applicable to
state chartered banking corporations.

Account.

     (a) The Securities Administrator will, from time to time on demand of the
Master Servicer, make or cause to be made such withdrawals or transfers from the
Distribution Account as the Master Servicer has designated for such transfer or

(limited in the case of amounts due the Master Servicer to those not withdrawn

Agreement):

          (i) to reimburse the Master Servicer or any Servicer for any Monthly
     Advance of its own funds or any advance of such Servicer's own funds, the
     right of the Master Servicer or a Servicer to reimbursement pursuant to
     this subclause (i) being limited to amounts received on a particular
     Mortgage Loan (including, for this purpose, the Purchase Price therefor,
     Insurance Proceeds and Liquidation Proceeds) which represent late payments
     or recoveries of the principal of or interest on such Mortgage Loan
     respecting which such Monthly Advance or advance was made;

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

     Mortgaged Property which was damaged by an Uninsured Cause or in connection
     with the liquidation of such Mortgage Loan;

          (iii) to reimburse the Master Servicer or any Servicer from Insurance
     Proceeds relating to a particular Mortgage Loan for insured expenses
     incurred with respect to such Mortgage Loan and to reimburse the Master
     Servicer or such Servicer from Liquidation Proceeds from a particular
     Mortgage Loan for Liquidation Expenses incurred with respect to such
     Mortgage Loan; provided that the Master Servicer shall not be entitled to
     reimbursement for Liquidation Expenses with respect to a Mortgage Loan to
     the extent that (i) any amounts with respect to such Mortgage Loan were
     paid as Excess Liquidation Proceeds pursuant to clause (xi) of this Section
     4.05(a) to the Master Servicer; and (ii) such Liquidation Expenses were not
     included in the computation of such Excess Liquidation Proceeds;

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

          (v) to pay the Master Servicer or any Servicer from the Purchase Price

     servicing compensation;

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


                                      -72-

<PAGE>

     limited to amounts received on the related Mortgage Loan (including, for
     this purpose, the Purchase Price therefor, Insurance Proceeds and
     Liquidation Proceeds) which represent late recoveries of the payments for
     which such advances were made;

          (vii) to reimburse the Master Servicer or any Servicer for any Monthly
     Advance or advance, after a Realized Loss has been allocated with respect
     to the related Mortgage Loan if the Monthly Advance or advance has not been
     reimbursed pursuant to clauses (i) and (vi);

          (viii) to pay the Master Servicer as set forth in Section 3.14;

          (ix) to reimburse the Master Servicer for expenses, costs and
     liabilities incurred by and reimbursable to it pursuant to this Agreement,
     including but not limited to Sections 3.03, 7.04(c) and (d);

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

          (xi) to reimburse or pay any Servicer any such amounts as are due
     thereto under the applicable Servicing Agreement and have not been retained
     by or paid to the Servicer, to the extent provided in the related Servicing
     Agreement;

          (xii) to reimburse the Trustee or the Securities Administrator for
     expenses, costs and liabilities incurred by or reimbursable to it pursuant
     to this Agreement;

          (xiii) to remove amounts deposited in error; and

          (xiv) to clear and terminate the Distribution Account pursuant to
     Section 10.01.

     (b) The Master Servicer shall keep and maintain separate accounting, on a
Mortgage Loan by Mortgage Loan basis, for the purpose of accounting for any
reimbursement from the Distribution Account pursuant to subclauses (i) through
(vi), inclusive, and (viii) or with respect to any such amounts which would have
been covered by such subclauses had the amounts not been retained by the Master
Servicer without being deposited in the Distribution Account under Section
4.02(b).

     (c) On each Distribution Date, the Securities Administrator shall
distribute the Available Funds to the Holders of the Certificates in accordance
with Section 6.01.

                                    ARTICLE V
                                  CERTIFICATES

     Section 5.01 The Certificates. The Certificates shall be executed by manual
or facsimile signature on behalf of the Securities Administrator by an
authorized officer. Certificates bearing the manual or facsimile signatures of
individuals who were, at the time when such signatures were affixed, authorized
to sign on behalf of the Securities Administrator shall bind the Issuing Entity,
notwithstanding that such individuals or any of them have ceased to be so
authorized prior to the authentication and delivery of such Certificates or did
not hold such offices


                                      -73-

<PAGE>

at the date of such authentication and delivery. No Certificate shall be
entitled to any benefit under this Agreement, or be valid for any purpose,
unless there appears on such Certificate a certificate of authentication
substantially in the form set forth as attached hereto executed by the
Securities Administrator by manual signature, and such certificate of
authentication upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly authenticated and delivered
hereunder. All Certificates shall be dated the date of their authentication. On
the Closing Date, the Securities Administrator shall authenticate the
Certificates to be issued at the written direction of the Depositor, or any
Affiliate thereof.

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

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

     At the option of a Certificateholder, Certificates may be exchanged for
other Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest upon surrender of the Certificates to be
exchanged at the office or agency of the Securities Administrator. Whenever any
Certificates are so surrendered for exchange, the Securities Administrator shall
execute, authenticate and deliver the Certificates that the Certificateholder
making the exchange is entitled to receive. Every Certificate presented or
surrendered for registration of Transfer or exchange shall be accompanied by a
written instrument of Transfer in form satisfactory to the Securities
Administrator duly executed by the holder thereof or his attorney duly
authorized in writing.

     No service charge to the Certificateholders shall be made for any
registration of Transfer or exchange of Certificates, but payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any Transfer or exchange of Certificates may be required. All
Certificates surrendered for registration of Transfer or exchange shall be
canceled and subsequently destroyed by the Securities Administrator in
accordance with such Securities Administrator's customary procedures.

     (b) No Transfer of an ERISA Restricted Certificate or Class A-R 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 an ERISA Restricted
Certificate or Class A-R Certificate by Merrill Lynch & Co.) each certify to
each Securities Administrator in writing the facts surrounding the Transfer in
substantially the form set forth in Exhibit F-1 (the "Transferor Representation
Letter") and (i)


                                      -74-

<PAGE>

deliver a letter in substantially the form of either Exhibit F-2 (the "Investor
Representation Letter") or Exhibit F-3 (the "Rule 144A Letter") or (ii) there
shall be delivered to the Securities Administrator an Opinion of Counsel that
such Transfer may be made pursuant to an exemption from the Securities Act,
which Opinion of Counsel shall not be an expense of the Depositor or the
Securities Administrator. The Depositor shall provide to any Holder of an ERISA
Restricted Certificate or Class A-R Certificate and any prospective transferee
designated by any such Holder, information regarding the related Certificates
and the Mortgage Loans and such other information as shall be necessary to
satisfy the condition to eligibility set forth in Rule 144A(d)(4) for Transfer
of any such Certificate without registration thereof under the Securities Act
pursuant to the registration exemption provided by Rule 144A. The Securities
Administrator shall cooperate with the Depositor in providing the Rule 144A
information referenced in the preceding sentence, including providing to the
Depositor such information in the possession of the Securities Administrator
regarding the Certificates, the Mortgage Loans and other matters regarding the
Trust Fund as the Depositor shall reasonably request to meet its obligation
under the preceding sentence. Each Holder of an ERISA Restricted Certificate or
Class A-R Certificate desiring to effect such Transfer shall, and does hereby
agree to, indemnify the Depositor and the Securities Administrator against any
liability that may result if the Transfer is not so exempt or is not made in
accordance with such federal and state laws.

     Notwithstanding the foregoing, no Transfer of a Class P Certificate
(including the initial issuance thereof) shall be registered unless the
prospective transferee certifies to the Securities Administrator that such
transferee is not acquiring the Class P Certificates as a "middleman" as that
term is defined in Treasury Regulation Section 1.671-5(b)(10) in a letter
substantially in the form set forth in Exhibit F-4 ("Middleman Representation
Letter").

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


                                      -75-

<PAGE>

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

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

     (c) Each Person who has or who acquires any Ownership Interest in a Class
A-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 A-R
Certificate are expressly subject to the following provisions:

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

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


                                      -76-

<PAGE>

     Section 5.02(c)(ii) shall not have been satisfied unless the Transferee's
     Letter includes such other form of declaration.

          (iii) Each Person holding or acquiring any Ownership Interest in a
     Class A-R Certificate shall agree (A) to obtain a Transferee's Letter from
     any other Person to whom such Person attempts to Transfer its Ownership
     Interest in a Class A-R Certificate, (B) to obtain a Transferee's Letter
     from any Person for whom such Person is acting as nominee, trustee or agent
     in connection with any Transfer of a Class A-R Certificate and (C) not to
     Transfer its Ownership Interest in a Class A-R Certificate or to cause the
     Transfer of an Ownership Interest in a Class A-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 A-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 Securities
     Administrator with a duly completed and effective Internal Revenue Service
     Form W-8ECI (or any successor thereto) and the Securities Administrator
     consents to such transfer, sale or other disposition in writing.

          (iv) Any attempted or purported Transfer of any Ownership Interest in
     a Class A-R Certificate in violation of the provisions of this Section
     5.02(c) 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 A-R Certificate in violation of the provisions of this Section
     5.02(c), 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 A-R Certificate. The Securities Administrator shall
     be under no liability to any Person for any registration of Transfer of a
     Class A-R Certificate that is in fact not permitted by Section 5.02(b) and
     this Section 5.02(c) 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 Transferee's Letter. The Securities
     Administrator shall be entitled but not obligated to recover from any
     Holder of a Class A-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
     A-R Certificate at and after either such time. Any such payments so
     recovered by the Securities Administrator shall be paid and delivered by
     the Securities Administrator to the last preceding Permitted Transferee of
     such Certificate.

          (v) At the option of the Holder of the Class A-R Certificate, the
     Class LT1-R Interest and the Residual Interest may be severed and
     represented by separate certificates; provided, however, that such separate
     certification may not occur until the Securities Administrator receives a
     REMIC Opinion to the effect that separate certification in the form and
     manner proposed would not result in the imposition of federal tax upon the
     Issuing Entity 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(b) and (c) will apply to each
     such separate certificate as if the separate certificate were a Class A-R
     Certificate. If, as evidenced by a REMIC Opinion, it is necessary to
     preserve the REMIC status of any of the REMICs provided for herein,


                                      -77-

<PAGE>

     the Class LT1-R Interest and the Residual Interest shall be severed and
     represented by separate Certificates.

     The restrictions on Transfers of a Class A-R Certificate set forth in this
Section 5.02(c) shall cease to apply (and the applicable portions of the legend
on a Class A-R Certificate may be deleted) with respect to Transfers occurring
after delivery to the Securities Administrator of an Opinion of Counsel, which
Opinion of Counsel shall not be an expense of the Securities Administrator 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 A-R Certificate hereby consents to any amendment of this Agreement that,
based on an Opinion of Counsel furnished to the Securities Administrator, is
reasonably necessary (a) to ensure that the record ownership of, or any
beneficial interest in, a Class A-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 A-R Certificate that is held by a
Person that is not a Permitted Transferee to a Holder that is a Permitted
Transferee.

     (d) The transferor of the Class A-R Certificate shall notify the Securities
Administrator in writing upon the transfer of the Class A-R Certificate.

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

     Section 5.03 Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any
mutilated Certificate is surrendered to the Securities Administrator or the
Securities Administrator receives evidence to its satisfaction of the
destruction, loss or theft of any Certificate and of the ownership thereof and
(b) there is delivered to the Securities Administrator such security or
indemnity as may be required by them to save each of them harmless, then, in the
absence of notice to the Securities Administrator that such Certificate has been
acquired by a bona fide purchaser, the Securities Administrator shall execute,
authenticate and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Certificate, a new Certificate of like Class, tenor
and Percentage Interest. In connection with the issuance of any new Certificate
under this Section 5.03, the Securities Administrator may require the payment of
a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto and any other expenses (including the fees and
expenses of the Securities Administrator) connected therewith. Any replacement
Certificate issued pursuant to this Section 5.03 shall constitute complete and
indefeasible evidence of ownership in the Trust Fund, as if originally issued,
whether or not the lost, stolen or destroyed Certificate shall be found at any
time. All Certificates surrendered to the Securities Administrator under the
terms of this Section 5.03 shall be canceled and destroyed by the Securities
Administrator in accordance with its standard procedures without liability on
its part.

     Section 5.04 Persons Deemed Owners. The Securities Administrator and any
agent of the Securities Administrator may treat the Person in whose name any
Certificate is registered as


                                      -78-

<PAGE>

the owner of such Certificate for the purpose of receiving distributions as
provided in this Agreement and for all other purposes whatsoever, and neither
the Securities Administrator, nor any agent of the Securities Administrator
shall be affected by any notice to the contrary.

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

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

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

     (b) the Depositor and the Securities Administrator may deal with the
Depository and the Depository Participants for all purposes (including the
making of distributions) as the authorized representative of the respective
Certificate Owners of the Book-Entry Certificates;

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

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

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


                                      -79-

<PAGE>

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

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

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

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

     Section 5.08 Definitive Certificates. If, after Book-Entry Certificates
have been issued with respect to any Certificates, (a) the Depository or the
Depositor advises the Securities Administrator that the Depository is no longer
willing, qualified or able to discharge properly its responsibilities under the
Depository Agreement with respect to such Certificates and the Securities
Administrator or the Depositor is unable to locate a qualified successor, (b)
the Depositor notifies the Securities Administrator and the Depository of its
intent to terminate the book-entry system through the Depository and, upon
receipt of notice of such intent from the Depository, the Certificate Owners of
the Book-Entry Certificates agree to initiate such termination or (c) after the
occurrence and continuation of an Event of Default, Certificate Owners of such
Book-Entry Certificates having not less than 51% of the Voting Rights evidenced
by any Class of Book-Entry Certificates advise the Securities Administrator and
the Depository in writing through the Depository Participants that the
continuation of a book-entry system with respect to Certificates of such Class
through the Depository (or its successor) is no longer in the best interests of
the Certificate Owners of such Class, then the Securities Administrator shall
notify all Certificate Owners of such Book-Entry Certificates, through the
Depository, of the occurrence of any such event and of the availability of
Definitive Certificates to Certificate Owners of such Class requesting the same.
The Depositor shall provide the Securities Administrator with an adequate
inventory of certificates to facilitate the issuance and transfer of Definitive
Certificates. Upon surrender to the Securities Administrator of any such
Certificates by the Depository, accompanied by registration instructions from
the Depository for registration, the Securities Administrator shall authenticate
and deliver such Definitive Certificates. Neither the Depositor nor the
Securities Administrator shall be liable for any delay in delivery of such
instructions and each may conclusively rely on, and shall be protected in
relying on, such instructions. Upon the issuance of such Definitive
Certificates, all references herein to obligations imposed upon or to be
performed by the Depository shall be deemed to be imposed upon and performed by
the Securities Administrator, to the extent applicable with respect to such
Definitive Certificates and the Securities Administrator shall recognize the
Holders of such Definitive Certificates as Certificateholders hereunder.

     Section 5.09 Maintenance of Office or Agency. The Securities Administrator
will maintain or cause to be maintained at its expense an office or offices or
agency or agencies where Certificates may be surrendered for registration of
transfer or exchange. The Securities Administrator initially designates its
offices at Sixth Street and Marquette Avenue, Minneapolis, Minnesota 55479,
Attention: Corporate Trust Services - Merrill Lynch Alternative Note Asset
Trust, Series 2007-OAR5 as offices for such purposes. The Securities
Administrator will give prompt written notice to the Certificateholders of any
change in such location of any such office or agency. For the avoidance of
doubt, the Securities Administrator may satisfy the requirements of this Section
5.09 by maintaining a single office or agency.

                                   ARTICLE VI
                         PAYMENTS TO CERTIFICATEHOLDERS

     Section 6.01 Distributions on the Certificates. (a) Interest and principal
on the Certificates will be distributed by the Securities Administrator monthly
on each Distribution Date, commencing in November 2007, as instructed by the
Master Servicer, in an aggregate amount equal to the sum of the Available Funds
for such Distribution Date. On each Distribution Date, the Available Funds shall
be distributed as follows:

          (A) On each Distribution Date, the Available Funds will be distributed
          in the following order of priority among the Certificates except as
          otherwise noted:

               first, to the Class P Certificates, any Prepayment Charges
               collected on the Mortgage Loans and (A) any amounts paid by the
               Seller or the related Servicer in respect of Prepayment Charges
               pursuant to this Agreement or the related Servicing Agreement and
               (B) any amounts received in respect of any indemnification paid
               as a result of a Prepayment Charges being unenforceable in breach
               of the representations and warranties set forth in the Mortgage
               Loan Purchase Agreement received during the related Prepayment
               Period;

               second, to the Senior Certificates, pro rata, the Accrued
               Certificate Interest for such Distribution Date. As described
               below, Accrued Certificate Interest is subject to reduction in
               the event of certain interest shortfalls allocable thereto. Any
               interest shortfalls shall be allocated among the Certificates as
               described below;

               third, to the Senior Certificates, pro rata, any Accrued
               Certificate Interest thereon remaining undistributed from
               previous Distribution Dates (reduced by any Deferred Interest
               previously allocated on each prior Distribution Date), to the
               extent of remaining Available Funds, any shortfall in available
               amounts being allocated to the Certificates in proportion to the
               amount of such Accrued Certificate Interest remaining
               undistributed for each class of Certificates for such
               Distribution Date;

               fourth, concurrently (i) sequentially to the Class A-R
               Certificate until the Certificate Principal Balance of such class
               has been reduced to zero and


                                      -81-

<PAGE>

               then to the Class A-1 and Class A-2 Certificates, pro rata, in
               reduction of their respective Certificate Principal Balances, the
               Senior Principal Distribution Amount for such Distribution Date
               to the extent of remaining Available Funds, until the Certificate
               Principal Balances of such classes have been reduced to zero and
               (ii) to the Class X Certificates, until the Certificate Principal
               Balance of such Class has been reduced to zero;

               fifth, sequentially, in the following order, to the Class M-1,
               Class M-2, Class M-3, Class B-1, Class B-2 and Class B-3
               Certificates, in each case up to an amount equal to and in the
               following order: (a) the Accrued Certificate Interest thereon for
               such Distribution Date (reduced by any Deferred Interest
               allocable thereto), (b) any Accrued Certificate Interest thereon
               remaining undistributed from previous Distribution Dates (reduced
               by any Deferred Interest previously allocated on each prior
               Distribution Date) and (c) such Class's Subordinate Principal
               Distribution Amount for such Distribution Date, in each case to
               the extent of the remaining Available Funds; and

               sixth, any Available Funds remaining after payment of interest
               and principal to the Classes of Certificates entitled thereto, as
               described above, will be distributed to the Class A-R
               Certificates.

     Any interest shortfall resulting from Deferred Interest on the Mortgage
Loans will be allocated first to the Class X Certificates (by increasing the
Class X-PO Component Principal Balance) to the extent of interest otherwise
accrued on such class for such Interest Accrual Period. Thereafter, Deferred
Interest for any Distribution Date will be allocated pro rata based upon the
Accrued Certificate Interest for each class other than the Class X Certificates
for such Distribution Date. The amount of the shortfall in Accrued Certificate
Interest distributable to each class of Certificates attributable to Net
Negative Amortization will be added to the Certificate Principal Balance of that
class. As a result of Net Negative Amortization, a portion of the interest
accrued on the Certificates will be distributed to such Certificates later than
otherwise anticipated.

     In addition to the foregoing distributions, with respect to any Subsequent
Recoveries, the Master Servicer shall deposit such amounts into the Master
Servicer Collection Account pursuant to Section 4.01(a). If, after taking into
account such Subsequent Recoveries, the amount of a Realized Loss is reduced,
the amount of such Subsequent Recoveries will be applied to increase the
Certificate Principal Balance of the Class of Subordinate Certificates with the
highest payment priority to which Realized Losses have been allocated, including
any Class of Subordinate Certificates to which a Realized Loss was previously
allocated and whose Certificate Principal Balance has been reduced to zero, but
not by more than the amount of Realized Losses previously allocated to that
Class of Certificates pursuant to Section 6.02. The amount of any remaining
Subsequent Recoveries will be applied to increase the Certificate Principal
Balance of the Class of Certificates with the next highest payment priority, up
to the amount of such Realized Losses previously allocated to that Class of
Certificates pursuant to Section 6.02, and so on. Holders of such Certificates
will not be entitled to any payment in respect of Accrued Certificate Interest
on the amount of such increases for any Interest Accrual


                                      -82-

<PAGE>

Period preceding the Distribution Date on which such increase occurs. Any such
increases shall be applied to the Certificate Principal Balance of each
Certificate of such Class in accordance with its respective Percentage Interest.

     Section 6.02 Allocation of Losses.

     (a) On or prior to each Determination Date, the Securities Administrator
shall determine the amount of any Realized Loss in respect of each Mortgage Loan
that occurred during the immediately preceding calendar month.

     (b) With respect to any Certificates on any Distribution Date, the
principal portion of each Realized Loss on a Mortgage Loan shall be allocated as
follows:

          first, to the Class B-3 Certificates until the Certificate Principal
     Balance thereof has been reduced to zero;

          second, to the Class B-2 Certificates until the Certificate Principal
     Balance thereof has been reduced to zero;

          third, to the Class B-1 Certificates until the Certificate Principal
     Balance thereof has been reduced to zero;

          fourth, to the Class M-3 Certificates until the Certificate Principal
     Balance thereof has been reduced to zero;

          fifth, to the Class M-2 Certificates until the Certificate Principal
     Balance thereof has been reduced to zero;

          sixth, to the Class M-1 Certificates until the Certificate Principal
     Balance thereof has been reduced to zero; and

          seventh, to the Senior Certificates, sequentially: first, to the Class
     X Certificates until the Class X-PO Component Principal Balance has been
     reduced to zero; second, to the Class A-2 Certificates until the
     Certificate Principal Balance thereof has been reduced to zero; and third
     to the Class A-1 Certificates until the Certificate Principal Balance
     thereof has been reduced to zero.

     (c) Notwithstanding the other provisions of Section 6.02, the first $0.01
of Realized Losses shall not be allocated to any Class of Certificates.

     Section 6.03 Payments.

     (a) On each Distribution Date, other than the final Distribution Date, the
Securities Administrator shall distribute to each Certificateholder of record on
the directly preceding Record Date the Certificateholder's pro rata share of its
Class (based on the aggregate Percentage Interest represented by such Holder's
Certificates) of all amounts required to be distributed on such Distribution
Date to such Class, based solely on information provided to the Securities
Administrator by the Master Servicer. The Securities Administrator shall
calculate the amount to be distributed to each Class and, based on such amounts,
the Securities Administrator shall determine the amount to


                                      -83-

<PAGE>

be distributed to each Certificateholder. All of the Securities Administrator's
calculations of payments shall be based solely on information provided to the
Securities Administrator by the Master Servicer or the applicable Servicer. The
Securities Administrator shall not be required to confirm, verify or recompute
any such information but shall be entitled to rely conclusively on such
information.

     (b) Payment of the above amounts to each Certificateholder shall be made
(i) by check mailed to each Certificateholder entitled thereto at the address
appearing in the Certificate Register or (ii) upon receipt by the Securities
Administrator on or before the fifth Business Day preceding the Record Date of
written instructions from a Certificateholder by wire transfer to a United
States dollar account maintained by the payee at any United States depository
institution with appropriate facilities for receiving such a wire transfer;
provided, however, that the final payment in respect of each Class of
Certificates will be made only upon presentation and surrender of such
respective Certificates at the office or agency of the Securities Administrator
specified in the notice to Certificateholders of such final payment.

remittance advices and the Monthly Statement.

     The Securities Administrator may make available each month, to any
interested party, the Monthly Statement to Certificateholders via the Securities
Administrator's website initially located at "www.ctslink.com." Assistance in
using the website can be obtained by calling the Securities Administrator's
customer service desk at (866) 846-4526. Parties that are unable to use the
above distribution option are entitled to have a paper copy mailed to them via
first class mail by calling the customer service desk and indicating such. The
Securities Administrator shall have the right to change the way such reports are
distributed in order to make such distribution more convenient and/or more
accessible to the parties, and the Securities Administrator shall provide timely
and adequate notification to all parties regarding any such change.

     (b) By January 30 of each year beginning in 2008, if so requested in
writing, the Securities Administrator will furnish such report to each Holder of
the Certificates of record at any time during the prior calendar year as to the
aggregate of amounts reported pursuant to subclauses (a)(ii) and (a)(v) above
with respect to the Certificates, plus information with respect to the amount of
servicing compensation and such other customary information as the Securities
Administrator may determine to be necessary and/or to be required by the
Internal Revenue Service or by a federal or state law or rules or regulations to
enable such Holders to prepare their tax returns for such calendar year. Such
obligations shall be deemed to have been satisfied to the extent that
substantially comparable information shall be provided by the Securities
Administrator pursuant to the requirements of the Code.

     Section 6.05 Monthly Advances. If the Monthly Payment on a Mortgage Loan
that was due on a related Due Date and is delinquent other than as a result of
application of the Relief Act and for which the related Servicer was required to
make an advance pursuant to the related Servicing Agreement exceeds the amount
deposited in the Master Servicer Collection Account that will be used for a
Monthly Advance with respect to such Mortgage Loan, the Master Servicer will
deposit in the Master Servicer Collection Account not later than the
Distribution Account Deposit Date immediately preceding the related Distribution
Date an amount equal to such deficiency, net of the Servicing Fee for such
Mortgage Loan, except to the extent the Master Servicer determines any such
Monthly Advance to be nonrecoverable from Liquidation Proceeds, Insurance
Proceeds or future payments on the Mortgage Loan for which such Monthly Advance
was made. If the Master Servicer has not deposited the amount described above as
of the related Distribution Account Deposit Date, the Trustee will, subject to
applicable law and its determination of recoverability, deposit in the Master
Servicer Collection Account not later than the related Distribution Date, an
amount equal to the remaining deficiency as of the Distribution Account Deposit
Date. Subject to the foregoing, the Master Servicer shall continue to make such
Monthly Advances through the date that the related Servicer is required to do so
under its Servicing Agreement. If applicable, on the Distribution Account
Deposit Date, the Master Servicer shall present an Officer's Certificate to the
Securities Administrator (i) stating that the Master Servicer elects not to make
a Monthly Advance in a stated amount and (ii) detailing the reason it deems the
advance to be nonrecoverable.

     Section 6.06 Compensating Interest Payments. The Master Servicer shall
deposit in the Master Servicer Collection Account not later than each
Distribution Account Deposit Date an amount equal to the aggregate amounts
required to be paid by the Servicers under the Servicing Agreements with respect
to subclause (a) of the definition of Prepayment Interest Shortfall with respect
to the Mortgage Loans for the related Distribution Date, and not so paid by the
related Servicers (such amount, the "Compensating Interest Payment"). The Master
Servicer shall not be entitled to any reimbursement of any Compensating Interest
Payment; provided, however, the aggregate Compensating Interest Payments made by
the Master Servicer shall not exceed the Master Servicing Compensation.

                      THE MASTER SERVICER AND THE DEPOSITOR

     Section 7.01 Liabilities of the Master Servicer. The Master Servicer shall
be liable in accordance herewith only to the extent of the obligations
specifically imposed upon and undertaken by the Master Servicer, as the case may
be, herein. The Depositor shall be liable in accordance herewith only to the
extent of the obligations specifically imposed upon and undertaken by the
Depositor.

     Section 7.02 Merger or Consolidation of the Master Servicer.

     (a) Each of the Master Servicer and the Depositor will keep in full force
and effect its existence, rights and franchises as a corporation under the laws
of the state of its incorporation, and will 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, the Certificates or any of the Mortgage Loans
and to perform its duties under this Agreement.

     (b) Any Person into which the Master Servicer or the Depositor may be
merged or consolidated, or any corporation resulting from any merger or
consolidation to which the Master Servicer shall be a party, or any Person
succeeding to the business of the Master Servicer, shall be the successor of the
Master Servicer hereunder, 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.

     Section 7.03 Indemnification from the Master Servicer and the Depositor.

     (a) The Master Servicer agrees to indemnify the Indemnified Persons for,
and to hold them harmless against, any loss, liability or expense (including
reasonable legal fees and disbursements of counsel) incurred on their part that
may be sustained in connection with, arising out of, or relating to, any claim
or legal action (including any pending or threatened claim or legal action)
relating to this Agreement or the Certificates (i) related to the Master
Servicer's failure to perform its duties in compliance with this Agreement
(except as any such loss, liability or expense shall be otherwise reimbursable
pursuant to this Agreement) or (ii) incurred by reason of the Master Servicer's
willful misfeasance, bad faith or gross negligence in the performance of duties
hereunder or by reason of reckless disregard of obligations and duties
hereunder, provided, in each case, that with respect to any such claim or legal
action (or pending or threatened claim or legal action), the Trustee or the
Securities Administrator shall have given the Master Servicer and the Depositor
written notice of such claim or legal action promptly after the Trustee or the
Securities Administrator shall have received knowledge thereof. This indemnity
shall survive the resignation or removal of the Trustee, Master Servicer or the
Securities Administrator and the termination of this Agreement.

     (b) The Depositor will indemnify any Indemnified Person for any loss,
liability or expense of any Indemnified Person not otherwise referred to in
Subsection (a) above.

     Section 7.04 Limitations on Liability of the Master Servicer and Others.
Subject to the obligation of the Master Servicer to indemnify the Indemnified
Persons pursuant to Section 7.03:

     (a) Neither the Master Servicer nor any of the directors, officers,
employees or agents of the Master Servicer shall be under any liability to the
Indemnified Persons, the Depositor, the Issuing Entity or the Certificateholders
for taking any action or for refraining from taking any action in good faith
pursuant to this Agreement, or for errors in judgment; provided, however, that
this provision shall not protect the Master Servicer or any such Person against
any breach of warranties or representations made herein or any liability which
would otherwise be imposed by reason of such Person's willful misfeasance, bad
faith or gross negligence in the performance of duties or by reason of reckless
disregard of obligations and duties hereunder.

     (b) The Master Servicer and any director, officer, employee or agent of the
Master 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.

     (c) The Master Servicer, the Custodian and any director, officer, employee
or agent of the Master Servicer or the Custodian shall be indemnified by the
Issuing Entity and held harmless thereby against any loss, liability or expense
(including reasonable legal fees and disbursements of counsel) incurred on their
part that may be sustained in connection with, arising out of, or related to,
any claim or legal action (including any pending or threatened claim or legal
action) relating to this Agreement, the Certificates or any Servicing Agreement
(except to the extent that the Master Servicer or the Custodian, as the case may
be, is indemnified by a Servicer thereunder), other than (i) any such loss,
liability or expense related to the Master Servicer's failure to perform its
duties in compliance with this Agreement (except as any such loss, liability or
expense shall be otherwise reimbursable pursuant to this Agreement), or to the
Custodian's failure to perform its duties under the Custodial Agreement,
respectively, or (ii) any such loss, liability or expense incurred by reason of
the Master Servicer's or the Custodian's willful misfeasance, bad faith or gross
negligence in the performance of duties hereunder or under the Custodial
Agreement, as applicable, or by reason of reckless disregard of obligations and
duties hereunder or under the Custodial Agreement, as applicable.

     (d) The Master Servicer shall not be under any obligation to appear in,
prosecute or defend any legal action that is not incidental to its duties under
this Agreement and that in its opinion may involve it in any expense or
liability; provided, however, the Master Servicer may in its discretion,
undertake any such action which it may deem necessary or desirable with respect
to this Agreement and the rights and duties of the parties hereto and the
interests of the Certificateholders hereunder. In such event, the legal expenses
and costs of such action and any liability resulting therefrom shall be
expenses, costs and liabilities of the Issuing Entity, and the Master Servicer
shall be entitled to be reimbursed therefor out of the Master Servicer
Collection Account as provided by Section 4.03. Nothing in this Section 7.04(d)
shall affect the Master Servicer's obligation to supervise, or to take such
actions as are necessary to ensure, the servicing and administration of the
Mortgage Loans pursuant to Section 3.01.

     (e) In taking or recommending any course of action pursuant to this
Agreement, unless specifically required to do so pursuant to this Agreement, the
Master Servicer shall not be required to investigate or make recommendations
concerning potential liabilities which the


                                      -89-

<PAGE>

Issuing Entity might incur as a result of such course of action by reason of the
condition of the Mortgaged Properties.

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

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

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

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

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


                                      -90-

<PAGE>

in effect immediately prior to such assignment, sale and delegation will not be
downgraded, qualified or withdrawn as a result of such assignment, sale and
delegation, as evidenced by a letter to such effect delivered to the Master
Servicer and the Trustee; and (iii) the Master Servicer assigning and selling
the master servicing shall deliver to the Trustee an Officer's Certificate and
an Opinion of Independent Counsel, each stating that all conditions precedent to
such action under this Agreement have been completed and such action is
permitted by and complies with the terms of this Agreement. No such assignment
or delegation shall affect any liability of the Master Servicer arising prior to
the effective date thereof.

                                  ARTICLE VIII
                                     DEFAULT

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

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

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

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

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


                                      -91-

<PAGE>

     insolvency or reorganization statute, makes an assignment for the benefit
     of its creditors, or voluntarily suspends payment of its obligations; or

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

In each and every such case, so long as such Event of Default with respect to
the Master Servicer shall not have been remedied, either the Trustee or the
Holders of Certificates evidencing Percentage Interests aggregating not less
than 51% of the principal of the Trust Fund, by notice in writing to the Master
Servicer (and to the Trustee if given by such Certificateholders), with a copy
to the Rating Agencies, and with the consent of the Depositor, may terminate all
of the rights and obligations (but not the liabilities) of the Master Servicer
under this Agreement and in and to the Mortgage Loans and/or the REO Property
serviced by the Master Servicer and the proceeds thereof. Upon the receipt by
the Master Servicer of the written notice, all authority and power of the Master
Servicer under this Agreement, whether with respect to the Certificates, the
Mortgage Loans, REO Property or under any other related agreements (but only to
the extent that such other agreements relate to the Mortgage Loans or related
REO Property) shall, subject to Section 8.02, automatically and without further
action pass to and be vested in the Trustee pursuant to this Section 8.01; and,
without limitation, the Trustee is hereby authorized and empowered to execute
and deliver, on behalf of the Master Servicer as attorney-in-fact or otherwise,
any and all documents and other instruments and to do or accomplish all other
acts or things necessary or appropriate to effect the purposes of such notice of
termination, whether to complete the transfer and endorsement or assignment of
the Mortgage Loans and related documents, or otherwise. The Master Servicer
agrees to cooperate with the Trustee in effecting the termination of the Master
Servicer's rights and obligations hereunder, including, without limitation, the
transfer to the Trustee of (i) the property and amounts which are then or should
be part of the Issuing Entity or which thereafter become part of the Issuing
Entity; and (ii) originals or copies of all documents of the Master Servicer
reasonably requested by the Trustee to enable it to assume the Master Servicer's
duties thereunder. In addition to any other amounts which are then, or,
notwithstanding the termination of its activities under this Agreement, may
become payable to the Master Servicer under this Agreement, the Master Servicer
shall be entitled to receive, out of any amount received on account of a
Mortgage Loan or related REO Property, that portion of such payments which it
would have received as reimbursement under this Agreement if notice of
termination had not been given. The termination of the rights and obligations of
the Master Servicer shall not affect any obligations incurred by the Master
Servicer prior to such termination.

     Section 8.02 Trustee to Act; Appointment of Successor.

     (a) Upon the receipt by the Master Servicer of a notice of termination
pursuant to Section 8.01 or an Opinion of Independent Counsel pursuant to
Section 7.05 to the effect that the Master Servicer is legally unable to act or
to delegate its duties to a Person which is legally able to act, the Trustee
shall automatically become the successor in all respects to the Master Servicer
in its capacity under this Agreement and the transactions set forth or provided
for herein and shall thereafter be subject to all the responsibilities, duties,
liabilities and limitations on liabilities relating thereto placed on the Master
Servicer by the terms and provisions hereof; provided,


                                      -92-

<PAGE>

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


                                      -93-

<PAGE>

     (b) If the Trustee shall succeed to any duties of the Master Servicer
respecting the Mortgage Loans as provided herein, it shall do so in a separate
capacity and not in its capacity as Trustee and, accordingly, the provisions of
Article IX (with the exception of the last paragraph of Section 9.01(d)) shall
be inapplicable to the Trustee in its duties as the successor to the Master
Servicer in the servicing of the Mortgage Loans (although such provisions shall
continue to apply to the Trustee in its capacity as Trustee); the provisions of
Article VII, however, shall apply to it in its capacity as successor master
servicer.

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

     Section 8.04 Waiver of Defaults. The Trustee shall transmit by mail to all
Certificateholders, within 60 days after the occurrence of any Event of Default
known to the Trustee, unless such Event of Default shall have been cured, notice
of each such Event of Default hereunder known to the Trustee. The Holders of
Certificates evidencing Percentage Interests aggregating not less than 51% of
the Trust Fund may, on behalf of all Certificateholders, waive any default by
the Master Servicer in the performance of its obligations hereunder and the
consequences thereof, except a default in the making of or the causing to be
made any required distribution on the Certificates. Upon any such waiver of a
past default, such default shall be deemed to cease to exist, and any Event of
Default arising therefrom shall be deemed to have been timely remedied for every
purpose of this Agreement. No such waiver shall extend to any subsequent or
other default or impair any right consequent thereon except to the extent
expressly so waived. The Trustee shall give notice of any such waiver to the
Rating Agencies.

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

                                   ARTICLE IX
                           CONCERNING THE TRUSTEE AND
                          THE SECURITIES ADMINISTRATOR

     Section 9.01 Duties of Trustee.

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


                                      -94-

<PAGE>

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

     (c) On each Distribution Date, the Securities Administrator shall make
monthly distributions and the final distribution to the Certificateholders from
funds in the Distribution Account as provided in Sections 6.01 and 10.02 herein
based solely on the report of the Master Servicer or the Servicers.

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

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

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

          (iii) Neither the Trustee nor the Securities Administrator shall be
     liable with respect to any action taken, suffered or omitted to be taken by
     it in good faith in accordance with the directions of the Holders of
     Certificates evidencing Percentage Interests aggregating not less than 25%
     of the Trust Fund, if such action or non-action


                                      -95-

<PAGE>

     relates to the time, method and place of conducting any proceeding for any
     remedy available to the Trustee or the Securities Administrator,
     respectively, or exercising any trust or other power conferred upon the
     Trustee or the Securities Administrator, respectively, under this
     Agreement;

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

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

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

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

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

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

     (f) Except for those actions that the Trustee or the Securities
Administrator is required to take hereunder, neither the Trustee nor the
Securities Administrator shall have any


                                      -96-

<PAGE>

obligation or liability to take any action or to refrain from taking any action
hereunder in the absence of written direction as provided hereunder.

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

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

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

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

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

          (v) Neither the Trustee nor the Securities Administrator shall be
     bound to make any investigation into the facts or matters stated in any
     resolution, certificate, statement, instrument, opinion, report, notice,
     request, consent, order, approval, bond or other paper or document, unless
     requested in writing to do so by Holders of Certificates evidencing
     Percentage Interests aggregating not less than 25% of the Trust Fund and
     provided that the payment within a reasonable time to the Trustee or the
     Securities Administrator, as applicable, of the costs, expenses or
     liabilities likely to be incurred by it in the making of such investigation
     is, in the opinion of the Trustee or the Securities Administrator, as
     applicable, reasonably assured to the Trustee or the Securities


                                      -97-

<PAGE>


     Administrator, as applicable, by the security afforded to it by the terms
     of this Agreement. The Trustee or the Securities Administrator may require
     reasonable indemnity against such expense or liability as a condition to
     taking any such action. The reasonable expense of every such examination
     shall be paid by the Certificateholders requesting the investigation;

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

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

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

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

          (x) Neither the Trustee nor the Securities Administrator shall have
     any duty to conduct any affirmative investigation (including, but not
     limited to, reviewing any reports delivered to the Trustee in connection
     with the review of Mortgage Files) as to the occurrence of any condition
     requiring the repurchase of any Mortgage Loan by the Seller pursuant to
     this Agreement or the Mortgage Loan Purchase Agreement, as applicable, or
     the eligibility of any Mortgage Loan for purposes of this Agreement.

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

     Section 9.03 Trustee and Securities Administrator Not Liable for
Certificates or Mortgage Loans. The recitals contained herein and in the
Certificates (other than, as to the Securities Administrator, the signature and
countersignature of the Securities Administrator on the Certificates) shall be
taken as the statements of the Depositor, and neither the Trustee nor the


                                      -98-

<PAGE>

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

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

     Section 9.05 Trustee's and Securities Administrator's Fees and Expenses.
The fees and expenses of the Trustee and the Securities Administrator shall be
paid by the Master Servicer in accordance with a side letter agreement. In
addition, the Trustee and the Securities Administrator will be entitled to
recover from the Master Servicer Collection Account pursuant to Section 4.03(b)
all reasonable out-of-pocket expenses, disbursements and advances and the
expenses of the Trustee and the Securities Administrator, respectively, in
connection with any Event of Default, any breach of this Agreement or any claim
or legal action (including any pending or threatened claim or legal action)
incurred or made by the Trustee or the Securities Administrator, respectively,
in the administration of the trusts hereunder (including the reasonable
compensation, expenses and disbursements of its counsel) except any such
expense, disbursement or advance as may arise from its negligence or intentional
misconduct or which is the responsibility of the Certificateholders or the Trust
Fund hereunder. If funds in the Master Servicer Collection Account are
insufficient therefor, the Trustee and the Securities Administrator shall
recover such expenses from the Depositor. Such compensation and


                                      -99-

<PAGE>

reimbursement obligation shall not be limited by any provision of law in regard
to the compensation of a trustee of an express trust.

     Section 9.06 Eligibility Requirements for Trustee and Securities
Administrator.

     (a) The Trustee and any successor Trustee and the Securities Administrator
and any successor Securities Administrator shall during the entire duration of
this Agreement be a state bank or trust company or a national banking
association organized and doing business under the laws of such state or the
United States of America, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus and undivided profits of at least
$40,000,000 or, in the case of a successor Trustee, $50,000,000, subject to
supervision or examination by federal or state authority and, in the case of the

successor Trustee or successor Securities Administrator other than pursuant to
Section 9.10, rated in one of the two highest long-term debt categories of, or
otherwise acceptable to, each of the Rating Agencies. If the Trustee publishes
reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid supervising or examining authority, then for the purposes of
this Section 9.06 the combined capital and surplus of such corporation shall be
deemed to be its total equity capital (combined capital and surplus) as set
forth in its most recent report of condition so published. In case at any time
the Trustee or the Securities Administrator shall cease to be eligible in
accordance with the provisions of this Section 9.06, the Trustee or the
Securities Administrator shall resign immediately in the manner and with the
effect specified in Section 9.08.

     (b) In addition, the Securities Administrator (i) may not be an Originator,
Master Servicer, Servicer, the Depositor or an affiliate of the Depositor unless

relevant entity, (ii) must be authorized to exercise corporate trust powers
under the laws of its jurisdiction of organization, and (iii) must be rated at

perform the duties of the Securities Administrator pursuant to this Agreement
until such time as a new Securities Administrator is appointed or (ii) petition
a court of competent jurisdiction to appoint a successor securities
administrator. The Trustee shall notify the Rating Agencies of any change of

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

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

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

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

     (c) The Holders of Certificates evidencing Percentage Interests aggregating

such Holders or their attorneys-in-fact duly authorized, one complete set of
which instruments shall be delivered to the Depositor, the Trustee, the
Securities Administrator (if the Trustee is removed), the Trustee (if the
Securities Administrator is removed), and the Trustee or Securities
Administrator so removed and the successor so appointed.

Trustee or Securities Administrator as provided in Section 9.09.

     Section 9.09 Successor Trustee and Successor Securities Administrator.

     (a) Any successor Trustee or Securities Administrator appointed as provided
in Section 9.08 shall execute, acknowledge and deliver to the Depositor, the
Master Servicer and its predecessor Trustee or Securities Administrator an
instrument accepting such appointment hereunder. The resignation or removal of
the predecessor Trustee or Securities Administrator shall then become effective
and such successor Trustee or Securities Administrator, without any further act,
deed or conveyance, shall become fully vested with all the rights, powers,
duties and obligations of its predecessor hereunder, with like effect as if
originally named as Trustee or Securities Administrator herein. The predecessor
Trustee or Securities Administrator shall after payment of its outstanding fees
and expenses promptly deliver to the successor Trustee or Securities
Administrator, as applicable, all assets and records of the Trust held by it
hereunder, and the Depositor and the predecessor Trustee or Securities
Administrator, as applicable, shall execute and deliver such instruments and do
such other things as may reasonably be required for more fully and certainly
vesting and confirming in the successor Trustee or Securities Administrator, as
applicable, all such rights, powers, duties and obligations.

     (b) No successor Trustee or Securities Administrator shall accept
appointment as provided in this Section 9.09 unless at the time of such
acceptance such successor Trustee or Securities Administrator shall be eligible
under the provisions of Section 9.06.

     (c) Upon acceptance of appointment by a successor Trustee or Securities
Administrator as provided in this Section 9.09, the successor Trustee or
Securities Administrator shall mail notice of the succession of such Trustee or
Securities Administrator hereunder to all Certificateholders at their addresses
as shown in the Certificate Register and to the Rating Agencies. The Depositor
shall pay the cost of any mailing by the successor Trustee or Securities
Administrator.

     Section 9.10 Merger or Consolidation of Trustee or Securities
Administrator. Any state bank or trust company or national banking association
into which the Trustee or the Securities Administrator may be merged or
converted or with which it may be consolidated or any state bank or trust
company or national banking association resulting from any merger, conversion or
consolidation to which the Trustee or the Securities Administrator,
respectively, shall be a party, or any state bank or trust company or national
banking association succeeding to all or substantially all of the corporate
trust business of the Trustee or the Securities Administrator, respectively,
shall be the successor of the Trustee or the Securities Administrator,
respectively, hereunder, provided such state bank or trust company or national
banking association shall be eligible under the provisions of Section 9.06. Such
succession shall be valid without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding.

     Section 9.11 Appointment of Co-Trustee or Separate Trustee.


                                      -102-

<PAGE>

     (a) Notwithstanding any other provisions hereof, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust or property constituting the same may at the time be located, the
Depositor and the Trustee acting jointly shall have the power and shall execute
and deliver all instruments to appoint one or more Persons approved by the
Trustee and the Depositor to act as co-trustee or co-trustees, jointly with the
Trustee, or separate trustee or separate trustees, of all or any part of the
Trust, and to vest in such Person or Persons, in such capacity, such title to
the Trust, or any part thereof, and, subject to the other provisions of this
Section 9.11, such powers, duties, obligations, rights and trusts as the
Depositor and the Trustee may consider necessary or desirable.

     (b) If the Depositor shall not have joined in such appointment within 15
days after the receipt by it of a written request so to do, the Trustee shall
have the power to make such appointment without the Depositor.

     (c) No co-Master Servicer or separate trustee hereunder shall be required
to meet the terms of eligibility as a successor trustee under Section 9.06
hereunder and no notice to Certificateholders of the appointment of
co-trustee(s) or separate trustee(s) shall be required under Section 9.08
hereof.

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

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

may, at any time, request the Trustee, its agent or attorney-in-fact, with full
power and authority, to do any lawful act under or with respect to 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.

shall pay any and all tax-related expenses (not including taxes) of each REMIC,
including but not limited to any professional fees or expenses related to audits
or any administrative or judicial proceedings with respect to such REMIC that
involve the Internal Revenue Service or state tax authorities, but only to the
extent that (i) such expenses are ordinary or routine expenses, including
expenses of a routine audit but not expenses of litigation (except as described
in (ii)); or (ii) such expenses or liabilities (including taxes and penalties)
are attributable to the negligence or willful misconduct of the Securities
Administrator in fulfilling its duties hereunder (including its duties as tax
return preparer). The Securities Administrator shall be entitled to
reimbursement of expenses to the extent provided in clause (i) above from the
Distribution Account, provided, however, the Securities Administrator shall not
be entitled to reimbursement for expenses incurred in connection with the
preparation of tax returns and other reports as required by this Section.

     (e) The Securities Administrator shall prepare and file, and the Trustee
shall sign, all of each REMIC's and the Trust Fund's federal and appropriate

upon receipt of additional reasonable compensation, to the Treasury or other
governmental authority such information as is necessary for the application of
any tax relating to the transfer of

Treasury Regulation 1.860E-2(a)(5) and any person designated in Section
860E(e)(3) of the Code.

     (g) The Securities Administrator and the Holders of Certificates shall take
any action or cause any REMIC to take any action necessary to create or maintain
the status of any REMIC as a REMIC under the REMIC Provisions and shall assist
each other as necessary to create or maintain such status. Neither the
Securities Administrator nor the Holder of any Residual Certificate shall
knowingly take any action, cause any REMIC to take any action or fail to take
(or fail to cause to be taken) any action that, under the REMIC Provisions, if
taken or not taken, as the case may be, could (i) endanger the status of any
REMIC as a REMIC or (ii) result in the imposition of a tax upon any REMIC
(including but not limited to the tax on prohibited transactions as defined in
Code Section 860F(a)(2) and the tax on prohibited contributions set forth on
Section 860G(d) of the Code) (either such event, an "Adverse REMIC Event")
unless the Securities Administrator has received a REMIC Opinion (at the expense
of the party seeking to take such action) to the effect that the contemplated
action will not endanger such status or result in the imposition of such a tax.
In addition, prior to taking any action with respect to any REMIC or the assets
therein, or causing any REMIC to take any action, which is not expressly
permitted under the terms of this Agreement, any Holder of a Residual
Certificate will consult with the Securities Administrator, in writing, with
respect to whether such action could cause an Adverse REMIC Event to occur with
respect to any REMIC, and no such Person shall take any such action or cause any
REMIC to take any such action as to which the Securities Administrator has
advised it in writing that an Adverse REMIC Event could occur; provided,
however, that if no Adverse REMIC Event would occur but such action could result
in the imposition of additional taxes on the Residual Certificateholders, no
such Person shall take any such action, or cause any REMIC to take any such
action without the written consent of the Residual Certificateholders.

     (h) Each Holder of a Residual Certificate shall pay when due any and all
taxes imposed on the related REMIC by federal or state governmental authorities.
To the extent that such taxes are not paid by a Residual Certificateholder, the
Securities Administrator shall pay any remaining REMIC taxes out of current or
future amounts otherwise distributable to the Holder of the Residual Certificate
in any such REMIC or, if no such amounts are available, out of other amounts
held in the Distribution Account, and shall reduce amounts otherwise payable to
holders of regular interests in any such REMIC, as the case may be.

     (i) The Securities Administrator shall prepare and file with the Internal
Revenue Service ("IRS"), on behalf of each of REMIC 1 and the Upper Tier REMIC,
an application for an employer identification number on IRS Form SS-4 or by any
other acceptable method. The Securities Administrator shall also file a Form
8811 as required. The Securities Administrator, upon receipt from the IRS of the
Notice of Taxpayer Identification Number Assigned, shall upon request promptly
forward a copy of such notice to the Depositor. The Securities Administrator
shall furnish any other information that is required by the Code and regulations
thereunder to be made available to Certificateholders. The Depositor shall cause
each Servicer to provide the Securities Administrator with such information as
is necessary for the Securities Administrator to prepare such reports.


                                      -105-

<PAGE>

     (j) No additional contributions of assets shall be made to any REMIC,
except as expressly provided in this Agreement.

     (k) The Securities Administrator shall not enter into any arrangement by
which any REMIC will receive a fee or other compensation for services.

     (l) The Class A-R Holder shall act as "tax matters person" with respect to
each REMIC and irrevocably appoints the Securities Administrator to act as its
agent in such roles.

     (m) The Securities Administrator shall prepare or cause to be prepared on
behalf of the Trust Fund, based upon information calculated in accordance with
this Agreement pursuant to instructions given by the Depositor, the Trustee
shall sign, and the Securities Administrator shall file federal tax returns, all
in accordance with Section 9.12 hereof. The Securities Administrator shall
prepare and file, and the Trustee shall sign, such state income tax returns and
such other returns as may be required by applicable law relating to the Trust
Fund, and, if required by state law, and shall file any other documents to the
extent required by applicable state tax law (to the extent such documents are in
the Securities Administrator's possession). The Securities Administrator shall
forward copies to the Depositor of all such returns and Form 1099 supplemental
tax information and such other information within the control of the Securities
Administrator as the Depositor may reasonably request in writing, and shall
distribute to each Certificateholder such forms and furnish such information
within the control of the Securities Administrator as are required by the Code
and the REMIC Provisions to be furnished to them, and will prepare and
distribute to Certificateholders Form 1099 (supplemental tax information) (or
otherwise furnish information within the control of the Securities
Administrator) to the extent required by applicable law.

     (n) None of the Securities Administrator, the Trustee or the Depositor, as
assignees under this Agreement, shall provide any consent pursuant to this
Agreement or knowingly take any action under this Agreement that would conflict
with or violate the provisions of this Section 9.12.

     (o) The parties intend that the portion of the Trust Fund consisting of the
right to receive the payments distributable to the Class P Certificates 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
Securities Administrator 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, and the Trustee shall sign, Form 1041
(together with any necessary attachments) and such other forms as may be
applicable. The parties intend that such grantor trust shall not be treated as a
WHFIT. The Securities Administrator shall have no obligation hereunder to
monitor whether such grantor trust will be treated as a WHFIT following the
Closing Date, and shall not be required hereunder to report under the WHFIT
Regulations except to the extent it receives written notice that the WHFIT
Regulations are applicable to such grantor trust.

     (p) Notwithstanding any other provision of this Agreement, the Securities
Administrator shall comply with all federal withholding requirements respecting
payments to


                                      -106-

<PAGE>

Certificateholders of interest or original issue discount on the Mortgage Loans
and the Certificates, that the Securities Administrator reasonably believes are
applicable under the Code. The consent of Certificateholders shall not be
required for such withholding. In the event the Securities Administrator
withholds any amount from interest or original issue discount payments or
advances thereof to any Certificateholder pursuant to federal withholding
requirements, the Securities Administrator shall, together with its monthly
report to such Certificateholders, indicate such amount withheld.

     (q) The Trustee and the Securities Administrator agree to indemnify the
Trust Fund and the Depositor for any taxes and costs including, without
limitation, any reasonable attorneys fees imposed on or incurred by the Trust
Fund, the Depositor or the Trustee, as a result of a breach of the Trustee's
covenants and the Securities Administrator's covenants, respectively, set forth
in this Section 9.12; provided, however, such liability and obligation to
indemnify in this paragraph shall not be joint and several and neither the
Trustee nor the Securities Administrator shall be liable or be obligated to
indemnify the Trust Fund for the failure by the other to perform any duty under
this Agreement or the breach by the other of any covenant in this Agreement.

     (r) The Securities Administrator covenants and agrees that it shall act as
agent (and the Securities Administrator is hereby appointed to act as agent) of
the Tax Matters Person on behalf of each of the REMICs provided for herein and
that in such capacity it shall: (a) to the extent that they are under its
control conduct the affairs of each of the REMICs 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; (b) 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; (c) 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; and (d) as and when necessary and
appropriate, represent each of the REMICs provided for herein in any
administrative or judicial 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.

     (s) Each of the Depositor, the Master Servicer, the Securities
Administrator and the Trustee agrees not to take or omit to take knowingly or
intentionally, 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.

     (t) The Depositor hereby instructs and authorizes the Securities
Administrator to make an appropriate election to treat each of the Upper Tier
REMIC and REMIC 1 as a REMIC. The Trustee shall sign the returns providing for
such elections and such other tax or information returns which are provided to
it. This Agreement shall be construed so as to carry out the


                                      -107-

<PAGE>

intention of the parties that each of the Upper Tier REMIC and REMIC 1 be
treated as a REMIC at all times prior to the date on which the Trust Fund is
terminated.

     The assets of REMIC 1 shall be all of the assets of the Trust Fund, other
than (i) amounts distributable to the Class P Certificates, (ii) the interests
issued by REMIC 1 and (iii) the grantor trusts described in this Section 9.12.
REMIC 1 shall issue the REMIC 1 Regular Interests, which shall be regular
interests of such REMIC, and shall issue the Class LT1-R Interest, which shall
be the sole class of residual interest in REMIC 1. Each of the REMIC 1 Regular
Interests shall have the characteristics set forth in the Preliminary Statement
and this Section 9.12.

     The assets of the Upper Tier REMIC shall be the REMIC 1 Regular Interests.
The Upper Tier REMIC Regular Interests shall be the regular interests in the
Upper Tier REMIC and the Residual Interest shall be the sole class of residual
interest in the Upper Tier REMIC.

     The beneficial ownership of the Class LT1-R Interest and the Residual
Interest shall be represented by the Class A-R Certificate. The Class LT1-R
Interest shall not have a principal balance or bear interest.

     (u) 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) received by REMIC 1 with respect to the Mortgage Loans shall be
paid to the REMIC 1 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 LT1-R
Interest.

     On each Distribution Date,

          (i) interest shortfalls with respect to the Mortgage Loans (other than
     interest shortfalls attributable to Negative Amortization) shall be
     allocated to the REMIC 1 Regular Interests pro rata based on the interest
     otherwise accrued thereon;

          (ii) the principal balance of each REMIC 1 Regular Interest shall be
     increased by the amount of interest accrued thereon (net of interest
     shortfalls allocated thereto pursuant to the immediately preceding clause
     (i));

          (iii) cash received by the REMIC 1 shall be distributed to, and losses
     with respect to the Mortgage Loans shall be allocated to:

                    first, to each class of REMIC 1 Marker Interest,
               sequentially, beginning with the REMIC 1 Marker Interest the
               Corresponding Certificate of which has the highest Pass-Through
               Rate through the REMIC 1 Marker Interest the Corresponding
               Certificate of which has the lowest Pass-Through Rate, in
               reduction of its principal balance so that its principal balance
               is as close as possible to 50% of the principal balance of its
               Corresponding Certificate; and

                    second, to the Class LT1Z Interest in reduction of its
               principal balance so that its principal balance equals the excess
               of (x) the aggregate


                                      -108-

<PAGE>

               Stated Principal Balance of the Mortgage Loans over (y) the
               aggregate principal balance of the REMIC 1 Marker Interests.

          If on any Distribution Date there is an increase in the Certificate
     Principal Balance of any Certificate due to Subsequent Recoveries pursuant
     to the definition of "Certificate Principal Balance", then there shall be a
     corresponding increase in the principal amount of the REMIC 1 Regular
     Interests allocated as follows:

                    first, to each of the REMIC 1 Regular Interests (other than
               the Class LT1Z) so that the principal balance of each such
               interest is as close as possible to 50% of the principal balances
               of its Corresponding Certificate; and

                    second, to the Class LT1Z Interest so that the principal
               balance of such interest equals the excess of (x) the aggregate
               Stated Principal Balance of the Mortgage Loans over (y) the
               aggregate principal balance of the REMIC 1 Marker Interests.

          The excess, if any, of amounts payable with respect to the REMIC
     regular interests held by the Upper Tier REMIC over the amounts payable
     with respect to the Upper Tier REMIC Regular Interests with respect to each
     Interest Accrual Period shall, solely for purposes of the REMIC Provisions,
     be deemed earned by the Securities Administrator as an additional fee,
     which amount shall be deemed paid by the Securities Administrator to the
     holders of the Class X Certificates. It is intended that the rights of the
     holders of the Class X Certificates to receive such deemed payments ("Class
     X Shortfalls") shall be treated as rights in respect of an interest rate
     cap contract written by the Securities Administrator in favor of the
     holders of the Class X Certificates and shall be accounted for as property
     separate and apart from the REMIC regular interests represented by the
     Class X Certificates. This provision is intended to comply with the
     requirements of Treasury Regulations Section 1.860G-2(i) for the treatment
     of property rights coupled with regular interests to be separately
     respected and shall be interpreted consistently with such regulation. For
     information reporting purposes, it will be assumed that the right to
     receive deemed payments in respect of Class X Shortfalls has no value. The
     Securities Administrator and the beneficial holders of the Class X
     Certificates by their acceptance of such Certificates agree that they will
     take tax reporting positions that allocate no more than a nominal value to
     such right and that they will adopt tax reporting positions consistent with
     the payments deemed made to the Class X Certificates in respect of Class X
     Shortfalls as payments in respect of interest rate cap agreements written
     by the Securities Administrator.

                                   TERMINATION

     Section 10.01 Termination upon Liquidation or Repurchase of all Mortgage
Loans.

     (a) Subject to Section 10.03, the obligations and responsibilities of the
Depositor, the Master Servicer, the Securities Administrator 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 of the last Mortgage Loan remaining in the Trust Fund (or any
Monthly Advance with respect thereto) 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 Securities Administrator 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"). The Depositor and the Securities Administrator 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 Securities Administrator 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 Issuing Entity). The Securities
Administrator shall accept the highest bid received at the Auction; provided
that the amount of such bid equals or exceeds the Optional Termination Price.
The Securities Administrator shall determine the Optional Termination Price
based upon information provided by (i) the Master Servicer with respect to the
amounts described in clauses (A) and (B) of the definition of "Optional
Termination Price" (other than Securities Administrator's expenses) and (ii) the
Depositor with respect to the information described in clause (C) of the
definition of "Optional Termination Price." The Securities Administrator 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.

     If an Optional Termination does not occur as a result of the Auction's
failure to achieve the Optional Termination Price, the Master 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. In connection with such termination, the
Optional Termination Price shall be delivered to the Securities Administrator no
later than the Business Day immediately preceding the related Distribution Date.
Notwithstanding anything to the contrary herein, the Optional Termination Amount
paid to the Securities Administrator by the winning bidder at the Auction or by
the Master Servicer shall be deposited by the Securities Administrator directly
into the Distribution Account immediately upon receipt. Upon any termination as
a result of an Auction, the Securities Administrator shall, out of the Optional
Termination Amount deposited into the Distribution Account, (x) pay the


                                      -110-
<PAGE>

Securities Administrator its costs and expenses necessary to conduct the Auction
and any other unreimbursed amounts owing to it and (y) pay to the Master
Servicer or Servicer, the aggregate amount of any unreimbursed out-of-pocket
costs and expenses owed to the Master Servicer or Servicer and any unpaid or
unreimbursed Servicing Fees, Monthly Advances and Servicing Advances.

     (c) Notwithstanding anything to the contrary in clause (b) above, in the
event that the Securities Administrator receives the written opinion of a
nationally recognized participant in mortgage finance acceptable to the Seller
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 Securities Administrator need not conduct the Auction. In such event, the
Master 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.

     Section 10.02 Final Distribution on the Certificates.

     If on any Determination Date, (i) the Securities Administrator determines
that there are no Outstanding Mortgage Loans and no other funds or assets in the
Trust Fund other than the funds in the Master Servicer Collection Account, the
Securities Administrator shall send a final distribution notice promptly to each
Certificateholder or (ii) the Securities Administrator determines that a Class
of Certificates shall be retired after a final distribution on such Class, the
Securities Administrator shall notify the Certificateholders within seven (7)
Business Days 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 Securities Administrator.

     Notice of any termination of the Issuing Entity, 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 Securities Administrator by letter to Certificateholders mailed no later
than the last calendar day of the month immediately preceding the month of such
final distribution (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 Securities Administrator will give such notice to
each Rating Agency at the time such notice is given to Certificateholders.

     In the event such notice is given, the Master Servicer shall cause all
funds in the Master Servicer Collection Account to be deposited in the
Distribution Account on the Business Day prior to the applicable Distribution
Date in an amount equal to the final distribution in respect of the
Certificates. Upon such final deposit with respect to the Issuing Entity and the
receipt by the Trustee, or its Custodian, of a Request for Release therefor, the
Trustee, or its Custodian, shall


                                      -111-

<PAGE>

promptly release to the Securities Administrator or the Master Servicer, as
applicable, the Mortgage Files for the Mortgage Loans.

     Upon presentation and surrender of the Certificates, the Securities
Administrator shall cause to be distributed to Certificateholders of each Class
the amounts allocable to such Certificates held in the Distribution Account in
the order and priority set forth in Section 6.01 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 Securities Administrator 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 Securities
Administrator 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 Issuing Entity. If within one
year after the second notice all Certificates shall not have been surrendered
for cancellation, the Class A-R Certificateholders shall be entitled to all
unclaimed funds and other assets of the Issuing Entity that remain subject
hereto. Upon payment to the Class A-R Certificateholders of such funds and
assets, the Securities Administrator shall have no further duties or obligations
with respect thereto.

     Section 10.03 Additional Termination Requirements.

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

          (i) Within 90 days prior to the final Distribution Date, the
     Securities Administrator shall adopt and sign a plan of complete
     liquidation of the Issuing Entity as provided to it by the terminating
     purchaser, meeting the requirements of a "qualified liquidation" under
     Section 860F of the Code and any regulations thereunder; and

          (ii) At or after the time of adoption of such a plan of complete
     liquidation and at or prior to the final Distribution Date, the Securities
     Administrator shall sell all of the assets of the Issuing Entity for cash
     pursuant to the terms of the plan of complete liquidation.

     (b) By their acceptance of Certificates, the Holders thereof hereby agree
to appoint the Securities Administrator as their attorney in fact to: (i) adopt
such a plan of complete liquidation (and the Certificateholders hereby appoint
the Securities Administrator as their attorney in fact to sign such plan) as
appropriate and (ii) to take such other action in connection


                                      -112-

<PAGE>

therewith as may be reasonably required to carry out such plan of complete
liquidation all in accordance with the terms hereof.

                            MISCELLANEOUS PROVISIONS

     Section 11.01 Intent of Parties. The parties intend that each REMIC shall
be treated as a REMIC for federal income tax purposes and that the provisions of
this Agreement should be construed in furtherance of this intent.

     Section 11.02 Amendment.

     (a) This Agreement may be amended from time to time by the Depositor, the
Master Servicer, the Securities Administrator and the Trustee, and without the
consent of any of the Certificateholders to:

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

               (ii) to correct, modify or supplement any provision herein which
     may be inconsistent with 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 Securities Administrator to such
     effect, adversely affect in any material respect the interests of any
     Certificateholder; 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.

     Notwithstanding the foregoing, without the consent of the
Certificateholders, the Depositor, the Master Servicer, the Securities
Administrator 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 Issuing Entity or any of the REMICs
provided for herein pursuant to the Code that would be a claim against the
Issuing Entity at any time prior to the final redemption of the Certificates,
provided that the Trustee and the Securities Administrator shall have been
provided an Opinion of Counsel addressed to the Trustee and the Securities
Administrator, which opinion shall be an expense of the party requesting such
amendment but in


                                      -113-

<PAGE>

any case shall not be an expense of the Trustee and the Securities
Administrator, 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.

     (b) This Agreement may also be amended from time to time by the Master
Servicer, the Depositor, the Securities Administrator and the Trustee, and the
Countrywide Assignment Agreement may also be amended from time to time by the
Master Servicer and the Trustee, with the consent of the Holders of Certificates
evidencing Percentage Interests aggregating not less than 51% of the Issuing
Entity or of the applicable Class or Classes, if such amendment affects only
such Class or Classes, 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 Certificateholders; provided, however,
that no such amendment shall (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 Regular Certificate without the consent of the Holder of such
Regular Certificate, or (ii) reduce the aforesaid percentage of Certificates the
Holders of which are required to consent to any such amendment, without the
consent of the Holders of all Certificates then outstanding. 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 addressed to the Trustee, 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 is permitted hereunder, that all
conditions precedent to the execution of such amendment have been satisfied and
that such amendment will not cause the imposition of any tax on the Issuing
Entity, 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.

     (c) Notwithstanding the foregoing, the Depositor shall not agree to any
modification or amendment of this Agreement that may adversely affect any
Servicer without the written consent of such Servicer.

     (d) Promptly after the execution of any such amendment, the Securities
Administrator shall furnish a copy of such amendment or written notification of
the substance of such amendment to each Certificateholder, with a copy to the
Rating Agencies.

     (e) In the case of an amendment under Section 11.02(b) above, it shall not
be necessary for the Certificateholders to approve the particular form of such
an amendment. Rather, it shall be sufficient if the Certificateholders approve
the substance of the amendment. 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.

     (f) Prior to the execution of any amendment to this Agreement, the Trustee
and the Securities Administrator shall be entitled to receive and rely upon an
Opinion of Counsel stating that the execution of such amendment will not
adversely affect the status of any REMIC created hereunder. The Trustee and the
Securities Administrator may, but shall not be obligated to, enter into any such
amendment which affects the Trustee's or the Securities Administrator's own
respective rights, duties or immunities under this Agreement.

     Section 11.03 Recordation of Agreement. To the extent permitted by
applicable law, this Agreement is subject to recordation in all appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the Mortgaged Properties are situated, and
in any other appropriate public recording office or elsewhere. The Depositor
shall effect such recordation, at the expense of the Issuing Entity upon the
request in writing of a Certificateholder, but only if such direction is
accompanied by an Opinion of Counsel (provided at the expense of the
Certificateholder requesting recordation) to the effect that such recordation
would materially and beneficially affect the interests of the Certificateholders
or is required by law.

     Section 11.04 Limitation on Rights of Certificateholders.

     (a) The death or incapacity of any Certificateholder shall not terminate
this Agreement or the Issuing Entity, nor entitle such Certificateholder's legal
representatives or heirs to claim an accounting or to take any action or
proceeding in any court for a partition or winding up of the Issuing Entity, nor
otherwise affect the rights, obligations and liabilities of the parties hereto
or any of them.

     (b) Except as expressly provided in this Agreement, no Certificateholders
shall have any right to vote or in any manner otherwise control the operation
and management of the Issuing Entity, 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 establish the Certificateholders from time
to time as partners or members of an association; nor shall any
Certificateholders be under any liability to any third Person by reason of any
action taken by the parties to this Agreement pursuant to any provision hereof.

     (c) No Certificateholder shall have any right by virtue of any provision of
this Agreement to institute any suit, action or proceeding in equity or at law
upon, under or with respect to this Agreement against the Depositor, the
Securities Administrator, the Master Servicer or any successor to any such
parties unless (i) such Certificateholder previously shall have given to the
Trustee a written notice of a continuing default, as herein provided, (ii) the
Holders of Certificates evidencing Percentage Interests aggregating not less
than 51% of the Trust Fund shall have made written request upon the Trustee to
institute such action, suit or proceeding in its own name as Trustee hereunder
and shall have offered to the Trustee such reasonable indemnity as it may
require against the costs and expenses and liabilities to be incurred therein or
thereby, and (iii) 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.

     (d) No one or more Certificateholders shall have any right by virtue of any
provision of this Agreement to affect the rights of any other Certificateholders
or to obtain or seek to obtain priority or preference over any other such
Certificateholder, or to enforce any right under this Agreement, except in the
manner herein provided and for the equal, ratable and common benefit of all
Certificateholders. For the protection and enforcement of the provisions of this
Section 11.04, each and every Certificateholder and the Trustee shall be
entitled to such relief as can be given either at law or in equity.

     Section 11.05 Acts of Certificateholders.

     (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Agreement to be given or taken by
Certificateholders may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Certificateholders in person or by
an agent duly appointed in writing. Except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
are delivered to the Trustee and, where it is expressly required, to the
Depositor. Proof of execution of any such instrument or of a writing appointing
any such agent shall be sufficient for any purpose of this Agreement and
conclusive in favor of the Trustee and the Depositor, if made in the manner
provided in this Section 11.05.

     (b) The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a signer acting in a capacity other than his or her individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his or her
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the individual executing the same, may also be proved in any
other manner which the Trustee deems sufficient.

     (c) The ownership of Certificates (notwithstanding any notation of
ownership or other writing on such Certificates, except an endorsement in
accordance with Section 5.02 made on a Regular Certificate presented in
accordance with Section 5.04) shall be proved by the Certificate Register, and
neither the Trustee, the Securities Administrator, the Depositor, the Master
Servicer nor any successor to any such parties shall be affected by any notice
to the contrary.

     (d) Any request, demand, authorization, direction, notice, consent, waiver
or other action of the holder of any Regular Certificate shall bind every future
holder of the same Regular Certificate and the holder of every Regular
Certificate issued upon the registration of transfer or exchange thereof, if
applicable, or in lieu thereof with respect to anything done, omitted or
suffered to be done by the Trustee, the Securities Administrator, the Depositor,
the Master Servicer or any successor to any such party in reliance thereon,
whether or not notation of such action is made upon such Certificates.

     (e) In determining whether the Holders of the requisite percentage of
Certificates evidencing Percentage Interests have given any request, demand,
authorization, direction, notice, consent or waiver hereunder, Certificates
owned by the Trustee, the Securities Administrator, the Depositor, the Master
Servicer or any Affiliate thereof shall be disregarded, except as otherwise
provided in Section 11.02(b) and except that, in determining whether the
Securities Administrator or the Trustee shall be protected in relying upon any
such request, demand, authorization, direction, notice, consent or waiver, only
Certificates which a Responsible Officer of the Trustee knows to be so owned
shall be so disregarded. Certificates which have been pledged in good faith to
the Trustee, the Securities Administrator, the Depositor, the Master Servicer or
any Affiliate thereof may be regarded as outstanding if the pledgor establishes
to the


                                      -116-

<PAGE>

satisfaction of the Securities Administrator the pledgor's right to act with
respect to such Certificates and that the pledgor is not an Affiliate of the
Trustee, the Securities Administrator, the Depositor, or the Master Servicer, as
the case may be.

covenants, agreements, provisions or terms of this Agreement shall be for any
reason whatsoever held invalid, then such covenants, agreements, provisions or

     Section 11.10 Article and Section Headings. The article and section
headings herein are for convenience of reference only, and shall not limit or
otherwise affect the meaning hereof.

     Section 11.11 Counterparts. This Agreement may be executed in two or more

but all of which together shall constitute one and the same instrument.

     Section 11.12 Notice to Rating Agencies. The article and section headings
herein are for convenience of reference only, and shall not limited or otherwise
affect the meaning hereof. The Trustee shall promptly provide notice to each
Rating Agency with respect to each of the following of which it has actual

     3. The resignation or termination of the Trustee or the Securities
Administrator;

     4. The repurchase or substitution of Mortgage Loans;

     5. The final payment to Certificateholders; and

                              REMIC ADMINISTRATION

     Section 12.01 [Reserved].

     Section 12.02 Prohibited Transactions and Activities. Neither the Depositor
nor the Securities Administrator shall sell, dispose of, or substitute for any
of the Mortgage Loans, except in a disposition pursuant to (i) the foreclosure
of a Mortgage Loan, (ii) the bankruptcy of the Trust Fund, (iii) the termination
of each REMIC pursuant to Article X of this Agreement, (iv) a substitution
pursuant to Article II of this Agreement or (v) a repurchase of Mortgage Loans
pursuant to Article II of this Agreement, nor acquire any assets for any REMIC,
nor sell or dispose of any investments in the Distribution Account for gain, nor
accept any contributions to any REMIC after the Closing Date, unless it has
received an Opinion of Counsel (at the expense of the party causing such sale,
disposition, or substitution) that such disposition, acquisition, substitution,
or acceptance will not (a) affect adversely the status of any such REMIC as a
REMIC or of the interests therein other than the Residual Certificate as the
regular interests


                                      -118-

<PAGE>

therein, (b) affect the distribution of interest or principal on the
Certificates, (c) result in the encumbrance of the assets transferred or
assigned to the Trust Fund (except pursuant to the provisions of this Agreement)
or (d) cause any such REMIC to be subject to any tax including a tax on
prohibited transactions or prohibited contributions pursuant to the REMIC
Provisions.

     Section 12.03 Indemnification with Respect to Prohibited Transactions or
Loss of REMIC Status. In the event that a REMIC 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 Securities Administrator of
its duties and obligations set forth herein, the Securities Administrator shall
indemnify the Certificateholders of the related Residual Certificate against any
and all losses, claims, damages, liabilities or expenses ("Losses") resulting
from such negligence; provided, however, that the Securities Administrator shall
not be liable for any such Losses attributable to the action or inaction of the
Depositor or the Holder of the Residual Certificate, nor for any such Losses
resulting from misinformation provided by any of the foregoing parties on which
the Securities Administrator has relied. Notwithstanding the foregoing, however,
in no event shall the Trustee or the Securities Administrator 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 or the Mortgage Loan Purchase Agreement, (2) for any
Losses other than arising out of malfeasance, willful misconduct or negligent
performance by the Securities Administrator with respect to its duties and
obligations set forth herein, and (3) for any special or consequential damages
to Certificateholders of the related Residual Certificate (in addition to
payment of principal and interest on the Certificates).

     Section 12.04 REO Property.

     (a) Notwithstanding any other provision of this Agreement, the Securities
Administrator shall not, except to the extent provided in this Agreement for
which the Securities Administrator is obligated to perform, knowingly permit any
Servicer to rent, lease, otherwise earn income or take any other action on
behalf of any REMIC with respect to any REO Property which might cause such REO
Property to fail to qualify as "foreclosure property" within the meaning of
section 860G(a)(8) of the Code or result in the receipt by any REMIC of any
"income from non-permitted assets" within the meaning of section 860F(a)(2) of
the Code or any "net income from foreclosure property" which is subject to tax
under the REMIC Provisions unless the Servicer has provided to the Securities
Administrator an Opinion of Counsel concluding that, under the REMIC Provisions,
such action would not adversely affect the status of any REMIC as a REMIC and
any income generated for any REMIC by the REO Property would not result in the
imposition of a tax upon such REMIC.

     (b) The Depositor shall cause each Servicer (to the extent provided in the
applicable Servicing Agreement) to make reasonable efforts to sell any REO
Property for its fair market value. In any event, however, the Depositor shall,
or shall cause the Servicer (to the extent provided in this Agreement) to,
dispose of any REO Property within three years of its acquisition by the Trust
Fund unless the Depositor or such Servicer (on behalf of the Trust Fund) has
received a grant of extension from the Internal Revenue Service to the effect
that, under the REMIC Provisions and any relevant proposed legislation and under
applicable state law, the REMIC may hold REO Property for a longer period
without adversely affecting the REMIC


                                      -119-

<PAGE>

status of such REMIC or causing the imposition of a Federal or state tax upon
such REMIC. If such an extension has been received, then the Depositor, acting
on behalf of the Trustee hereunder, shall, or shall cause the Servicer to,
continue to attempt to sell the REO Property for its fair market value for such
period longer than three years as such extension permits (the "Extended
Period"). If such an extension has not been received and the Depositor or the
Servicer, acting on behalf of the Trust Fund hereunder, is unable to sell the
REO Property within 33 months after its acquisition by the Trust Fund or if such
an extension has been received and the Depositor or the Servicer is unable to
sell the REO Property within the period ending three months before the close of
the Extended Period, the Depositor shall cause the Servicer, before the end of
the three-year-period or the Extended Period, as applicable, to (i) purchase
such REO Property at a price equal to the REO Property's fair market value or
(ii) auction the REO Property to the highest bidder (which may be the Servicer)
in an auction reasonably designed to produce a fair price prior to the
expiration of the three-year period or the Extended Period, as the case may be.

FOLLOWING THE INITIAL ISSUANCE OF THE CERTIFICATES, THE PRINCIPAL BALANCE OF

DEPOSITORY TRUST COMPANY TO THE DEPOSITOR OR ITS AGENT FOR REGISTRATION OF
TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE
NAME OF CEDE & CO. OR SUCH OTHER NAME AS REQUESTED BY AN AUTHORIZED
REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY AND ANY PAYMENT IS MADE TO CEDE &
CO., ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO
ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN
INTEREST HEREIN.

IF ANY BOOK-ENTRY CERTIFICATE (OR ANY INTEREST THEREIN) IS ACQUIRED OR HELD IN
VIOLATION OF THE CERTIFICATE TRANSFER RESTRICTIONS IN THE AGREEMENT, THEN THE
LAST PRECEDING TRANSFEREE THAT IS IN COMPLIANCE WITH SUCH PROVISIONS SHALL BE
RESTORED, TO THE EXTENT PERMITTED BY LAW, TO ALL RIGHTS AND OBLIGATIONS AS
CERTIFICATE OWNER THEREOF RETROACTIVE TO THE DATE OF SUCH TRANSFER OF SUCH
CERTIFICATE. NEITHER THE TRUSTEE NOR THE SECURITIES ADMINISTRATOR SHALL BE UNDER
ANY LIABILITY TO ANY PERSON FOR MAKING ANY PAYMENTS DUE ON SUCH CERTIFICATE TO

FOREGOING PROVISIONS OF ERISA OR THE CODE ("SIMILAR LAW"), AND IS NOT DIRECTLY
OR INDIRECTLY ACQUIRING THIS CERTIFICATE FOR, ON BEHALF OF, OR WITH ANY ASSETS
OF ANY SUCH PLAN, (B) IF THE CERTIFICATE HAS BEEN THE SUBJECT OF AN
ERISA-QUALIFYING UNDERWRITING, A REPRESENTATION 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

SATISFACTORY TO THE SECURITIES ADMINISTRATOR, AND UPON WHICH THE SECURITIES
ADMINISTRATOR SHALL BE ENTITLED TO RELY, TO THE EFFECT THAT THE ACQUISITION AND
HOLDING OF SUCH CERTIFICATE BY THE PROSPECTIVE TRANSFEREE WILL NOT CONSTITUTE OR
RESULT IN A NONEXEMPT PROHIBITED TRANSACTION UNDER ERISA OR THE CODE OR A
VIOLATION OF SIMILAR LAW AND WILL NOT SUBJECT THE SECURITIES ADMINISTRATOR, THE
TRUSTEE, THE SERVICERS, THE MASTER SERVICER OR THE DEPOSITOR TO ANY OBLIGATION
IN ADDITION TO THOSE UNDERTAKEN BY SUCH ENTITIES IN THE AGREEMENT, WHICH OPINION
OF COUNSEL SHALL NOT BE AN EXPENSE OF THE SECURITIES ADMINISTRATOR, THE TRUSTEE,

is exempt from the registration requirements under the 1933 Act and such state
securities laws. In the event that a transfer is to be made in reliance upon an

state laws.

          No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Securities Administrator may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Certificates.

the Trustee and any agent of the Depositor, the Securities Administrator, the

or exchange of Certificates, but the Securities Administrator may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Certificates.

Distribution Account may be made from time to time for purposes other than
distributions to Holders of the Certificates, such purposes including
reimbursement of advances made, or certain expenses incurred, with respect to
the Mortgage Loans.

          The Agreement may be amended from time to time in the manner specified
in the Agreement.

          As provided in the Agreement and subject to certain limitations set
forth therein, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Securities Administrator as
provided in the Agreement, duly endorsed by, or accompanied by an assignment in
the form below or other written instrument of transfer in form satisfactory to
the Securities Administrator duly executed by, the Holder hereof or such
Holder's attorney duly authorized in writing, and thereupon one or more new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest will be issued to the designated transferee or
transferees.

          The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations set forth therein, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

          No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Securities Administrator may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Certificates.

          The Depositor, the Securities Administrator, the Master Servicer and
the Trustee and any agent of the Depositor, the Securities Administrator, the
Master Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all

Servicer, the Trustee nor any such agent shall be affected by notice to the

          The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment (or provision for payment) to the Holders
of the Certificates of all amounts held by the Securities Administrator and
required to be paid to them pursuant to the Agreement following the earlier of
(i) the Distribution Date on which the Certificate Principal Balance of each
Class of Certificates has been reduced to zero, (ii) the final payment (or any
advance with respect thereto) on or other liquidation of the last Mortgage Loan
remaining in the Trust Fund and (iii) the Optional Termination of the trust fund
according to the procedures described in the Agreement.

          The recitals contained herein shall be taken as statements of the
Depositor and the Securities Administrator assumes no responsibility for their
correctness.

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

Wells Fargo Bank, N.A.
9062 Old Annapolis Road
Columbia, Maryland 21045
Attention: Corporate Trust Services - Merrill Lynch Alternative Note Asset
Trust, Series 2007-OAR5

Ladies and Gentlemen:

We propose to purchase Merrill Lynch Alternative Note Asset Trust, Series
2007-OAR5 Mortgage Pass-Through Certificates, Class A-R, described in the
Prospectus Supplement, dated October 30, 2007, and the Prospectus, dated May 15,
2007. Capitalized terms used but not defined herein shall have the meanings
assigned to them in the Pooling and Servicing Agreement dated October 1, 2007
relating to this issuance of the Merrill Lynch Alternative Note Asset Trust,
Series 2007-OAR5 Mortgage Pass-Through Certificates (the "Pooling and servicing
Agreement").

1. We certify that (a) we are not a disqualified organization and (b) we are not
purchasing such Class A-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 and covenant 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 A-R Certificate, we may incur tax liabilities in
excess of any cash flows generated by the Class A-R Certificate, (d) we intend
to pay any taxes associated with holding the Class A-R Certificate as they
become due and (e) we will not cause income from the Class A-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 A-R
Certificate and:(1)

          __________ The Class A-R Certificate will be registered in our name.

          __________ The Class A-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 A-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 A-R
Certificate in connection with the conduct of a trade or business within the
United States and have furnished the transferor and the Securities Administrator
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 A-R
Certificate to us absolutely null and void and shall cause no rights in the
Class A-R Certificate to vest in us.

6. We covenant and agree that in the event that at some future time we wish to
transfer any interest in the Class A-R Certificate, (a) we will transfer such
interest in the Class A-R Certificate only to a transferee that (i) is not a
disqualified organization and is not purchasing such interest in the Class A-R
Certificate on behalf of a disqualified organization, (ii) is a U.S. person or
will hold the Class A-R Certificate in connection with the conduct of a trade or
business within the United States and will furnish us and the Securities
Administrator 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 and
(iii) has delivered to the Securities Administrator a letter in the form of this
letter (including the affidavit appended hereto) and (b) we will provide the
Securities Administrator a written statement substantially in the form of
Exhibit E-2 to the Pooling and Servicing Agreement.

7. We hereby designate _______________________ as our fiduciary to act as the
tax matters person for each of the REMICs provided for in the Pooling and
Servicing Agreement in which the Class A-R Certificate represents the residual
interest.

                                        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
                    "Investor"),

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

               3.   the Investor 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 Alternative Note Asset Trust,
                    Series 2007-OAR5 Mortgage Pass-Through Certificates, Class
                    A-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 Investor, the Investor 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 Investor has historically paid its debts as they became
                    due,

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

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

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

               10.  the Investor 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 A-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 A-R Certificate to a foreign permanent establishment
                    or fixed base (within the meaning of an applicable income
                    tax treaty) of the Investor, and as to each of the residual
                    interests represented by the Class A-R Certificate, the
                    present value of the anticipated tax liabilities associated
                    with holding such residual interest does not exceed the sum
                    of:


                                     E-1-4

<PAGE>

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

               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 Investor 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 Investor 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
          Investor;]

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

          (B)  the Investor 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 A-R Certificate (i)
               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
               (ii) 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 Investor 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 Investor to make this
declaration or to satisfy the requirements of Treasury regulation Section
1.860E-1(c)(5)(i).]

(12) The Investor has agreed in writing that it will not cause income from the
Class A-R Certificate to be attributable to a foreign permanent establishment or
fixed base (within the meaning of an applicable income tax treaty) of the
Investor or another U.S. taxpayer.

Attestations and Assessments of Compliance.

          (a) The Custodian, as the duly appointed agent of the Trustee for
these purposes, acknowledges (subject to any exceptions noted in the Initial
Certification referred to in Section 2.3(a)) receipt of the Mortgage Files
relating to the Mortgage Loans identified on the schedule attached hereto (the

provide a report on assessment of compliance or an attestation with respect to
itself and with respect to any Subcontractor shall be suspended in any year in
which the Issuing Entity's reporting obligations under the Exchange Act are
suspended.

          (d) The Custodian has not and shall not engage any Subcontractor which

assessment and a statement of registered public accounting firm certifying its
compliance with the applicable servicing criteria in Item 1122(d) of Regulation
AB as of and for the period ending the end of the fiscal year ending no later
than December 31 of the year prior to the year of delivery of the report.

or authority of the Custodian.

          (e) The Custodian agrees to indemnify the Company, the Master
Servicer, the Trustee, the Trust Fund and each of their respective directors,
officers, employees and agents and hold each of them harmless from and against
any losses, damages, penalties, fines, forfeitures, legal fees and expenses and
related costs, judgments, and any other costs, fees and expenses that any of
them may sustain arising out of or based upon the engagement of any
Subcontractor in violation of Section 2.1(d) or any failure by the Custodian to
deliver any information, report, certification, accountants' letter or other
material when and as required under this Agreement, including any report under
Sections 2.1(b) or 2.1(c).

          Section 2.02 Reserved.

          Section 2.03 Review of Mortgage Files.

          (a) On or prior to the Closing Date, the Custodian agrees, for the
benefit of Certificateholders, to review, in accordance with the provisions of
Section 2.02 of the Pooling and Servicing Agreement, each such document, and
shall deliver to the Company and the Trustee an Initial Certification in the
form annexed hereto as Exhibit One evidencing receipt (subject to any exceptions
noted therein) of a Mortgage File for each of the Mortgage Loans listed on the
Schedule attached as Exhibit B to the Pooling and Servicing Agreement (the
"Mortgage Loan Schedule") and certifying that all such documents have been
executed and received and that such documents relate to the Mortgage Loans
identified on the Mortgage Loan Schedule, except for any exceptions listed on
Schedule A attached to such Initial Certification. The Custodian shall be under
no duty or obligation to inspect, review or examine said documents, instruments,
certificates or other papers to determine that the same are genuine,
enforceable, or appropriate for the represented purpose or that they have
actually been recorded or that they are other than what they purport to be on
their face.

          (b) Not later than 180 days after the Closing Date, the Custodian
shall review the Mortgage Files as provided in Section 2.02 of the Pooling and
Servicing Agreement and deliver to the Company and the Trustee a Final

Pooling and Servicing Agreement, the Custodian shall make no representation as
to and shall not be responsible to verify (i) the validity, legality,
enforceability, due authorization, recordability, sufficiency or genuineness of
any of the documents included in any Mortgage File or (ii) the collectibility,
insurability, effectiveness or suitability of any of the documents in any
Mortgage File.

          Upon receipt of written request from the Trustee, the Custodian shall
as soon as practicable supply the Trustee with a list of all of the documents
relating to the Mortgage Loans then contained in the Mortgage Files.

          Section 2.04 Notification of Breaches of Representations and
Warranties. Upon discovery by the Custodian of a breach of any representation or
warranty made by the Company as set forth in the Pooling and Servicing Agreement
with respect to a Mortgage Loan relating to a Mortgage File, the Custodian shall
give prompt written notice to the Company, the related Servicer and the Trustee.

          Section 2.05 Custodian to Cooperate: Release of Mortgage Files. Upon
receipt of written notice from the Master Servicer that the Mortgage Loan Seller
has repurchased a Mortgage Loan pursuant to Article II of the Pooling and
Servicing Agreement, and that the purchase price therefor has been deposited in
the Master Servicer Collection Account or the Distribution Account, then the
Custodian agrees to promptly release to the Mortgage Loan Seller the related
Mortgage File.

          Upon the Custodian's receipt of a request for release (a "Request for
Release") substantially in the form of Exhibit D to the Pooling and Servicing
Agreement signed by a Servicing Officer of the related Servicer stating that it
has received payment in full of a Mortgage Loan or that payment in full will be
escrowed in a manner customary for such purposes, the Custodian agrees promptly
to release to such Servicer the related Mortgage File. The Company shall deliver
to the Custodian and the Custodian agrees to accept the Mortgage Note and other
documents constituting the Mortgage File with respect to any Substitute Mortgage
Loan.

          From time to time as is appropriate for the servicing or foreclosure
of any Mortgage Loan, including, for this purpose, collection under any Primary
Mortgage Insurance Policy, the related Servicer shall deliver to the Custodian a
Request for Release signed by a Servicing Officer requesting that possession of
all of the Mortgage File be released to such Servicer and certifying as to the
reason for such release and that such release will not invalidate any insurance
coverage provided in respect of the Mortgage Loan under any of the Insurance
Policies. Upon receipt of the foregoing, the Custodian shall deliver the
Mortgage File to such Servicer. The related Servicer shall cause each Mortgage
File or any document therein so released to be returned to the Custodian when
the need therefore by such Servicer no longer exists, unless (i) the Mortgage
Loan has been liquidated and the Liquidation Proceeds relating to the Mortgage
Loan have been deposited in the Master Servicer Collection Account or the
Distribution Account or (ii) the Mortgage File or such document has 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


                                       G-4

Property either judicially or non-judicially, and the related Servicer has
delivered to the Custodian a certificate of a Servicing Officer certifying as to
the name and address of the Person to which such Mortgage File or such document
was delivered and the purpose or purposes of such delivery.

          At any time that a Servicer is required to deliver to the Custodian a
Request for Release, such Servicer shall deliver two copies of the Request for
Release if delivered in hard copy or such Servicer may furnish such Request for
Release electronically to the Custodian, in which event the Servicing Officer
transmitting the same shall be deemed to have signed the Request for Release. In
connection with any Request for Release of a Mortgage File because of a
repurchase of a Mortgage Loan, the related Servicer shall send to the Trustee an
assignment of mortgage, without recourse, representation or warranty from the
Trustee to the Mortgage Loan Seller and the related Mortgage Note which shall be
endorsed without recourse, representation or warranty by the Trustee and the
Trustee shall forward such documents to the Mortgage Loan Seller. In connection
with any Request for Release of a Mortgage File because of the payment in full
of a Mortgage Loan, the related Servicer shall send to the Trustee a certificate
of satisfaction or other similar instrument to be executed by or on behalf of
the Trustee and returned to such Servicer.

          Section 2.06 Assumption Agreements. In the event that any assumption
agreement or substitution of liability agreement is entered into with respect to
any Mortgage Loan subject to this Agreement in accordance with the terms and
provisions of the Pooling and Servicing Agreement, the Master Servicer, to the
extent provided in the related Servicing Agreement, shall cause the related
Servicer to notify the Custodian that such assumption or substitution agreement
has been completed by forwarding to the Custodian the original of such
assumption or substitution agreement, which shall be added to the related
Mortgage File and, for all purposes, shall be considered a part of such Mortgage
File to the same extent as all other documents and instruments constituting
parts thereof.

                                   ARTICLE III
                            CONCERNING THE CUSTODIAN

          Section 3.01 Custodian a Bailee and Agent of the Trustee. With respect
to each Mortgage Note, Mortgage and other documents constituting each Mortgage
File which are delivered to the Custodian, the Custodian is exclusively the
bailee and agent of the Trustee and has no instructions to hold any Mortgage
Note or Mortgage for the benefit of any person other than the Trustee and the
Certificateholders and undertakes to perform such duties and only such duties as
are specifically set forth in this Agreement. Except upon compliance with the
provisions of Section 2.5 of this Agreement, no Mortgage Note, Mortgage or
Mortgage File shall be delivered by the Custodian to the Company, the Servicer
or the Master Servicer or otherwise released from the possession of the
Custodian.

          Section 3.02 Reserved.

          Section 3.04 Master Servicer to Pay Custodian's Fees and Expenses. The
Master Servicer covenants and agrees to pay to the Custodian from time to time,
and the Custodian shall be entitled to, reasonable compensation for all services
rendered by it in the exercise and performance of any of the powers and duties
hereunder of the Custodian, and the Master Servicer will pay or reimburse the
Custodian upon its request for all reasonable expenses, disbursements and
advances incurred or made by the Custodian in accordance with any of the
provisions of this Agreement (including the reasonable compensation and the
expenses and disbursements of its counsel and of all persons not regularly in
its employ), except any such expense, disbursement or advance as may arise from
its negligence or bad faith or to the extent that such cost or expense is
indemnified by the Company pursuant to the Pooling and Servicing Agreement.

          Section 3.05 Custodian May Resign; Trustee May Remove Custodian. The
Custodian may resign from the obligations and duties hereby imposed upon it as
such obligations and duties relate to its acting as Custodian of the Mortgage
Loans. Upon receiving such notice of resignation, the Trustee shall either take
custody of the Mortgage Files itself and give prompt notice thereof to the
Company, the Master Servicer and the Custodian, or promptly appoint a successor
Custodian by written instrument, in duplicate, one copy of which instrument
shall be delivered to the resigning Custodian and one copy to the successor
Custodian. If the Trustee shall not have taken custody of the Mortgage Files and
no successor Custodian shall have been so appointed and have accepted
appointment within 30 days after the giving of such notice of resignation, the
resigning Custodian may petition any court of competent jurisdiction for the
appointment of a successor Custodian.

          The Trustee may remove the Custodian at any time with the consent of
the Master Servicer. In such event, the Trustee shall appoint, or petition a
court of competent jurisdiction to appoint, a successor Custodian hereunder. Any
successor Custodian shall be a depository institution subject to supervision or
examination by federal or state authority, shall be able to satisfy the other
requirements contained in Section 3.7 and shall be unaffiliated with the
Servicer or the Company.

          Any resignation or removal of the Custodian and appointment of a
successor Custodian pursuant to any of the provisions of this Section 3.5 shall
become effective upon acceptance of appointment by the successor Custodian. The
Trustee shall give prompt notice to the Company and the Master Servicer of the
appointment of any successor Custodian. No successor Custodian shall be
