            THIS POOLING AND SERVICING AGREEMENT, dated as of February 1, 2005,
among MORGAN STANLEY ABS CAPITAL I INC., a Delaware corporation, as depositor
(the "Depositor"), COUNTRYWIDE HOME LOANS SERVICING LP, a Texas limited
partnership, as servicer (the "Servicer"), WMC MORTGAGE CORP., a California
corporation, as responsible party (the "Responsible Party"), WELLS FARGO BANK,
NATIONAL ASSOCIATION, a national banking association, as custodian (the
"Custodian"), and DEUTSCHE BANK NATIONAL TRUST COMPANY, a national banking
association, as trustee (the "Trustee"),

                               W I T N E S S E T H:

            In consideration of the mutual agreements herein contained, the
parties hereto agree as follows:

                              PRELIMINARY STATEMENT

            The Trustee shall elect that two segregated asset pools within the
Trust Fund be treated for federal income tax purposes as comprising two REMICs
(each, a "REMIC" or, in the alternative, the Lower Tier REMIC and the Upper Tier
REMIC, respectively). Each Class of Certificates (other than the Class P and
Class R Certificates), other than the right of each Class of LIBOR Certificates
to receive Basis Risk CarryForward Amounts and the right of the Class X
Certificates to receive payments from the Interest Rate Cap Agreements,
represents ownership of a regular interest in the Upper Tier REMIC for purposes
of the REMIC Provisions. The Class R Certificate represents ownership of the
sole class of residual interest in each of the Lower Tier REMIC and the Upper
Tier REMIC for purposes of the REMIC Provisions. The Startup Day for each REMIC
described herein is the Closing Date. The latest possible maturity date for each
Certificate is the latest date referenced in Section 2.05. The Upper Tier REMIC
shall hold as assets the several classes of uncertificated Lower Tier Regular
Interests, set out below. Each such Lower Tier Regular Interest is hereby
designated as a regular interest in the Lower Tier REMIC. The Class LT-A-1ss,
Class LT-A-1mz, Class LT-A-2a, Class LT-A-2b, Class LT-A-2c, Class LT-M-1, Class
LT-M-2, Class LT-M-3, Class LT-M-4, Class LT-M-5, Class LT-M-6, Class LT-B-1,
Class LT-B-2 and Class LT-B-3 Interests are hereby designated the LT Accretion
Directed Classes (the "LT Accretion Directed Classes"). The Class P Certificates
represent beneficial ownership of the Prepayment Charges, each Class of LIBOR
Certificates represents beneficial ownership of a regular interest in the Upper
Tier REMIC and the right to receive Basis Risk CarryForward Amounts and the
Class X Certificates represent beneficial ownership of a regular interest in the
Upper Tier REMIC, the Excess Reserve Fund Account and the Interest Rate Cap
Agreements, which portions of the Trust Fund shall be treated as a grantor
trust.

------------

(1)    The   interest   rate   with   respect   to any   Distribution   Date for these
      interests is a per annum variable rate equal to the WAC Cap.

(2)    The interest rate with respect to any Distribution Date for the Class
      LT-Group I Interest is a per annum variable rate (expressed as a
      percentage rounded to eight decimal places) equal to the Loan Group I Cap.

(3)    The interest rate with respect to any Distribution Date for the Class
      LT-Group II Interest is a per annum variable rate (expressed as a
      percentage rounded to eight decimal places) equal to the Loan Group II
      Cap.

(4)    For all Distribution Dates, the Lower Tier Principal Amount of these Lower
      Tier Regular Interests shall be rounded to eight decimal places.

(5)    The Class LT-R Interest is the sole class of residual interest in the
      Lower Tier REMIC and it does not have a principal amount or an interest
      rate.

            The   Lower   Tier   REMIC   shall   hold as assets   all of the   assets
included in the Trust Fund other than   Prepayment   Charges,   the Interest Rate
Cap   Agreements,   the Excess Reserve Fund Account,   and the Lower Tier Regular
Interests.

            On each Distribution Date, 50% of the increase in the Subordinated
Amount will be payable as a reduction of the Lower Tier Principal Amounts of the
LT Accretion Directed Classes (each such Class will be reduced by an amount
equal to 50% of any increase in the Subordinated Amount that is attributable to
a reduction in the Class Certificate Balance of its Corresponding Class) and
will be accrued and added to the Lower Tier Principal Amount of the Class
LT-Accrual Interest. On each Distribution Date, the increase in the Lower Tier
Principal Amount of the Class LT-Accrual Interest may not exceed interest
accruals for such Distribution Date for the Class LT-Accrual Interest. In the
event that: (i) 50% of the increase in the Subordinated Amount exceeds (ii)
interest accruals on the Class LT-Accrual Interest for such Distribution Date,
the excess for such Distribution Date (accumulated with all such excesses for
all prior Distribution Dates) will be added to any increase in the Subordinated
Amount for purposes of determining the amount of interest accrual on the Class
LT-Accrual Interest payable as principal on the LT Accretion Directed Classes on
the next Distribution Date pursuant to the first sentence of this paragraph. All
payments of scheduled principal and prepayments of principal generated by the
Mortgage Loans shall be allocated (i) 50% to the Class LT-Accrual Interest, the
Class LT-Group I Interest and the Class LT-Group II Interest (and further
allocated among these Lower Tier Regular Interests in the manner described
below) and (ii) 50% to the LT Accretion Directed Classes (principal payments
shall be allocated among such LT Accretion Directed Classes in an amount equal
to 50% of the principal amounts allocated to their respective Corresponding
Classes), until paid in full. Notwithstanding the above, principal payments
allocated to the Class X Certificates that result in the reduction in the
Subordinated Amount shall be allocated to the Class LT-Accrual Interest (until
paid in full). Realized Losses shall be applied so that after all distributions
have been made on each Distribution Date (i) the Lower Tier Principal Amount of
each LT Accretion Directed Class is equal to 50% of the Class Certificate
Balance of its Corresponding Class, and (ii) the Class LT-Accrual Interest, the
Class LT-Group I Interest and the Class LT-Group II Interest (and further
allocated among these Lower Tier Regular Interests in the manner described
below) is equal to 50% of the aggregate Stated Principal Balance of the Mortgage
Loans plus 50% of the Subordinated Amount. As among the Class LT-Accrual
Interest, the Class LT-Group I Interest and the Class LT-Group II Interest, all
payments of scheduled principal and prepayments of principal generated by the
Mortgage Loans, and all Realized Losses, allocable to such Lower Tier Regular
Interests shall be allocated (i) to the Class LT-Group I Interest and the Class
LT-Group II Interest, each from the related Loan Group so that their respective
Lower-Tier Principal Amounts (computed to at least eight decimal places) are
equal to 0.001% of the aggregate Stated Principal Balance of the Mortgage Loans
in the related Loan Group and (ii) the remainder to the Class LT-Accrual
Interest.

            The Upper Tier REMIC shall issue the following classes of Upper Tier
Regular Interests and each such interest, other than the Class UT-R Interest, is
hereby designated as a regular interest in the Upper Tier REMIC.

      WAC Cap.

(7)    The Class X Interest has an initial principal balance of $34,433,233, but
      it will not accrue interest on such balance but will accrue interest on a
      notional principal balance. As of any Distribution Date, the Class X
      Interest shall have a notional principal balance equal to the aggregate of
      the principal balances of the Lower Tier Regular Interests as of the first
      day of the related Interest Accrual Period. With respect to any Interest
      Accrual Period, the Class X Interest shall bear interest at a rate equal
      to the excess, if any, of the WAC Cap over the product of (i) 2 and (ii)
      the weighted average Lower Tier Interest Rates of the Lower Tier Regular
      Interests, where the Lower Tier Interest Rates on each of the Class
      LT-Accrual Interest, Class LT-Group I Interest and Class LT-Group II
      Interest is subject to a cap equal to zero and each LT Accretion Directed
      Class is subject to a cap equal to the Pass-Through Rate on its
      Corresponding Class. With respect to any Distribution Date, interest that
      so accrues on the notional principal balance of the Class X Interest shall
      be deferred in an amount equal to any increase in the Subordinated Amount
      on such Distribution Date. Such deferred interest shall not itself bear
      interest. The Class X Certificates will represent beneficial ownership of
      the Class X Interest, the Interest Rate Cap Agreements, and amounts in the
      Excess Reserve Fund Account, subject to the obligation to make payments
      from the Excess Reserve Fund Account in respect of Basis Risk CarryForward
      Amounts. For federal income tax purposes, the Trustee will treat a Class X
      Certificateholder's obligation to make payments from the Excess Reserve
      Fund Account as payments made pursuant to an interest rate cap contract
      written by the Class X Certificateholders in favor of each Class of LIBOR
      Certificates. Such rights of the Class X Certificateholders and LIBOR
      Certificateholders shall be treated as held in a portion of the Trust Fund
      that is treated as a grantor trust under subpart E, Part I of subchapter J
      of the Code.

(8)    The Class UT-R Interest is the sole class of residual interest in the
      Upper Tier REMIC. The Class UT-R Interest does not have an interest rate.

(9)    Each of these Certificates will represent not only the ownership of the
      Corresponding Class of Upper Tier Regular Interest but also the right to
      receive payments from the Excess Reserve Fund Account in respect of any
      Basis Risk CarryForward Amounts. For federal income tax purposes, the
      Trustee will treat a Certificateholder's right to receive payments from
      the Excess Reserve Fund Account as payments made pursuant to an interest
      rate cap contract written by the Class X Certificateholders.

            The minimum denomination for each Class of Certificates, other than
the Class P, Class R and the Class X Certificates, will be $25,000 with integral
multiples of $1 in excess thereof. The minimum denomination for the Class P and
the Class X Certificates will each be a 1% Percentage Interest in such Class.
The Class R Certificate will represent a 100% Percentage Interest in such Class.

            It is expected   that each Class of   Certificates   will receive its
final   distribution   of   principal   and   interest   on or   prior   to the   Final
Scheduled Distribution Date.

      equivalent document executed in connection with the Mortgage (if
      provided).

            The Responsible Party shall cause to be delivered to the Trustee or
Custodian, as applicable, the applicable recorded document promptly upon receipt
from the respective recording office but in no event later than one year from
the date on which the Responsible Party sold the related Mortgage Loan to the
Purchaser.

            If any Mortgage has been recorded in the name of MERS or its
designee, no Assignment of Mortgage in favor of the Trustee will be required to
be prepared or delivered and instead, the Servicer shall take all reasonable
actions as are necessary to cause the Trust to be shown as the owner of the
related Mortgage Loan on the records of MERS for the purpose of the system of
recording transfers of beneficial ownership of Mortgages maintained by MERS.

            From time to time, the Depositor or the Servicer, as applicable,
shall forward to the Trustee or Custodian, as applicable, additional original
documents, additional documents evidencing an assumption, modification,
consolidation or extension of a Mortgage Loan, in accordance with the terms of
this Agreement upon receipt of such documents. All such mortgage documents held
by the Trustee or Custodian, as applicable, as to each Mortgage Loan shall
constitute the "Custodial File."

            On or prior to the Closing Date, the Responsible Party shall deliver
to the Trustee or the Custodian, as applicable, Assignments of Mortgages, in
blank, for each Mortgage Loan. The Responsible Party shall cause the Assignments
of Mortgages and complete recording information to be provided to the Servicer
in a reasonably acceptable manner. No later than thirty (30) Business Days
following the later of the Closing Date and the date of receipt by the Servicer
of the complete recording information for a Mortgage, the Servicer shall
promptly submit or cause to be submitted for recording, at the expense of the
Responsible Party and at no expense to the Trust Fund, the Trustee, the
Servicer, or the Depositor, in the appropriate public office for real property
records, each Assignment of Mortgage referred to in Section 2.01(b)(v).
Notwithstanding the foregoing, however, for administrative convenience and
facilitation of servicing and to reduce closing costs, the Assignments of
Mortgage shall not be required to be completed and submitted for recording with
respect to any Mortgage Loan (i) if the Trustee and each Rating Agency have
received an Opinion of Counsel, satisfactory in form and substance to the
Trustee and each Rating Agency to the effect that the recordation of such
Assignments of Mortgage in any specific jurisdiction is not necessary to protect
the Trustee's interest in the related Mortgage Note, (ii) if such Mortgage Loan
is a MERS Designated Mortgage Loan or (iii) if the Rating Agencies have each
notified the Depositor in writing that not recording any such Assignments of
Mortgage would not cause the initial ratings on any LIBOR Certificates to be
downgraded or withdrawn; provided, however, that the Servicer shall not be held
responsible or liable for any loss that occurs because an Assignment of Mortgage
was not recorded, but only to the extent that the Servicer does not have prior
knowledge of the act or omission that causes such loss. However, with respect to
the Assignments of Mortgage referred to in clauses (i), (ii) and (iii) above, if
foreclosure proceedings occur against a Mortgaged Property, the Depositor shall
notify the Servicer and the Servicer shall record such Assignment of Mortgage at
the expense of the Responsible Party. If the Assignment of Mortgage is to be
recorded, the Mortgage shall be assigned to "Deutsche Bank National Trust
Company, as trustee under the Pooling and Servicing Agreement dated as of
February 1, 2005, Morgan Stanley ABS Capital I Inc. Trust 2005-WMC1". In the
event that any such Assignment of Mortgage is lost or returned unrecorded
because of a defect therein, the Responsible Party shall promptly cause to be
delivered a substitute Assignment of Mortgage to cure such defect and thereafter
cause each such assignment to be duly recorded.

            In the event that such original or copy of any document submitted
for recordation to the appropriate public recording office is not so delivered
to the Trustee or Custodian, as applicable, within one year following the date
on which the Responsible Party sold the related Mortgage Loan to the Purchaser,
and in the event that the Responsible Party does not cure such failure within 30
days of discovery or receipt of written notification of such failure from the
Depositor, the related Mortgage Loan shall, upon the request of the Depositor,
be repurchased by the Responsible Party at the price and in the manner specified
in Section 2.03. The foregoing repurchase obligation shall not apply in the
event that the Responsible Party cannot deliver such original or copy of any
document submitted for recordation to the appropriate public recording office
within the specified period due to a delay caused by the recording office in the
applicable jurisdiction; provided, that the Responsible Party shall instead
deliver a recording receipt of such recording office or, if such recording
receipt is not available, an officer's certificate of an officer of the
Responsible Party, confirming that such document has been accepted for
recording.

            Notwithstanding anything to the contrary contained in this Section
2.01, in those instances where the public recording office retains or loses the
original Mortgage or assignment after it has been recorded, the obligations of
the Responsible Party shall be deemed to have been satisfied upon delivery by
the Responsible Party to the Trustee or the Custodian, as applicable, prior to
the Closing Date of a copy of such Mortgage or assignment, as the case may be,
certified (such certification to be an original thereof) by the public recording
office to be a true and complete copy of the recorded original thereof.

            On or prior to the Closing Date, the Depositor shall deliver to the
Trustee and the Custodian a copy of the Data Tape Information in an electronic,
machine readable medium in a form mutually acceptable to the Trustee or
Custodian, as applicable.

            (c) The Depositor does hereby establish, pursuant to the further
provisions of this Agreement and the laws of the State of New York, an express
trust (the "Trust") to be known, for convenience, as "MORGAN STANLEY ABS CAPITAL
I INC. TRUST 2005-WMC1" and Deutsche Bank National Trust Company is hereby
appointed as Trustee in accordance with the provisions of this Agreement. The
parties hereto acknowledge and agree that it is the policy and intention of the
Trust to acquire only Mortgage Loans meeting the requirements set forth in this
Agreement, including without limitation, the representation and warranty set
forth in paragraph (43) of Schedule III.

            (d) The Trust shall have the capacity, power and authority, and the
Trustee on behalf of the Trust is hereby authorized, to accept the sale,
transfer, assignment, set over and conveyance by the Depositor to the Trust of
all the right, title and interest of the Depositor in and to the Trust Fund
(including, without limitation, the Mortgage Loans) pursuant to Section 2.01(a).
The Trustee on behalf of the Trust is hereby authorized to enter into the
Interest Rate Cap Agreements.

            Section 2.02 Acceptance by the Trustee of the Mortgage Loans. The
Trustee and the Custodian shall acknowledge, on the Closing Date, receipt by the
Trustee or the Custodian, as applicable, of the documents identified in the
Initial Certification in the form annexed hereto as Exhibit E, and declares that

pursuant to Section 2.01, and that it holds or will hold such other assets as
are included in the Trust Fund, in trust for the exclusive use and benefit of
all present and future Certificateholders. The Trustee and the Custodian shall
maintain possession of the related Mortgage Notes in the State of California
unless otherwise permitted by the Rating Agencies.

            In connection with the Closing Date, the Trustee and the Custodian
shall be required to deliver via facsimile (with original to follow the next
Business Day) to the Depositor and the Servicer an Initial Certification prior
to the Closing Date, or, with the Depositor's consent, on the Closing Date,
certifying receipt of a Mortgage Note and Assignment of Mortgage for each
Mortgage Loan. Neither the Trustee nor the Custodian shall be responsible for
verifying the validity, sufficiency or genuineness of any document in any
Custodial File.

             Within 90 days after the Closing Date, the Trustee and the Custodian
shall ascertain that all documents identified in the Document Certification and
Exception Report in the form attached hereto as Exhibit F are in its possession,
and shall deliver to the Depositor, the Servicer and the Trustee (if delivered
by the Custodian) a Document Certification and Exception Report, in the form
annexed hereto as Exhibit F, to the effect that, 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 such certification as an exception and
not covered by such certification): (i) all documents identified in the Document
Certification and Exception Report and required to be reviewed by it are in its
possession; (ii) such documents have been reviewed by it and appear regular on
their face and relate to such Mortgage Loan; (iii) based on its examination and
only as to the foregoing documents, the information set forth in items (1), (2),
(7) and (9) of the Mortgage Loan Schedule and items (1), (9) and (17) of the
Data Tape Information respecting such Mortgage Loan is correct; and (iv) each
Mortgage Note has been endorsed as provided in Section 2.01 of this Agreement.
Neither the Trustee nor the Custodian shall be responsible for verifying the
validity, sufficiency or genuineness of any document in any Custodial File.

            The Trustee and the Custodian shall retain possession and custody of
each Custodial File in accordance with and subject to the terms and conditions
set forth herein. The Servicer shall promptly deliver to the Trustee or to the
Custodian, as applicable, upon the execution or receipt thereof, the originals
of such other documents or instruments constituting the Custodial File as come
into the possession of the Servicer from time to time.

            The Responsible Party shall deliver to the Servicer copies of all
trailing documents required to be included in the Custodial File at the same
time the original or certified copies thereof are delivered to the Trustee or to
the Custodian, including but not limited to such documents as the title

Party at the Responsible Party's expense to the Servicer.

            Section 2.03 Representations and Warranties; Remedies for Breaches
of Representations and Warranties with Respect to the Mortgage Loans. (a) The
Servicer hereby makes the representations and warranties set forth in Schedule
II hereto to the Depositor and the Trustee, as of the dates set forth in such
schedule.

            (b) The Responsible Party hereby makes the representations and
warranties, set forth in Schedule III and Schedule IV hereto, to the Depositor,
the Servicer and the Trustee as of the dates set forth in such schedules.

            (c) The Depositor hereby makes the representations and warranties
set forth in Schedule V hereto to the Trustee as of the date set forth in such
schedule.

            (d) The Custodian hereby makes the representations and warranties
set forth in Schedule VI hereto to the Trustee as of the date set forth in such
schedule.

            (e) It is understood and agreed by the parties hereto that the
representations and warranties set forth in this Section 2.03 shall survive the
transfer of the Mortgage Loans by the Depositor to the Trustee, and shall inure
to the benefit of the parties to whom the representations and warranties were
made notwithstanding any restrictive or qualified endorsement on any Mortgage
Note or Assignment of Mortgage or the examination or failure to examine any
Mortgage File. Upon discovery by any of the Responsible Party, the Depositor,
the Trustee or the Servicer of a breach of any of the foregoing representations
and warranties that materially and adversely affect the value of any Mortgage
Loan or the interest of the Trustee or the Certificateholders therein, the party
discovering such breach shall give prompt written notice to the other parties.

            (f) Within 30 days of the earlier of either discovery by or notice
to the Responsible Party that any Mortgage Loan does not conform to the
requirements as determined in the Trustee's or the Custodian's review of the
related Custodial File or within 60 days of the earlier of either discovery by
or notice to the Responsible Party of any breach of a representation or
warranty, set forth in Section 2.03(b), that materially and adversely affects
the value of any Mortgage Loan or the interest of the Trustee or the
Certificateholders therein, the Responsible Party shall use commercially
reasonable efforts to cause to be remedied a material defect in a document
constituting part of a Mortgage File or promptly to cure such breach in all
material respects and, if such defect or breach cannot be remedied, the
Responsible Party shall, at the Depositor's option as specified in writing and
provided to the Responsible Party and the Trustee, (i) if such 30 or 60 day
period, as applicable, expires prior to the second anniversary of the Closing
Date, remove such Mortgage Loan (a "Deleted Mortgage Loan") from the Trust Fund
and substitute in its place a Substitute Mortgage Loan, in the manner and
subject to the conditions set forth in this Section 2.03; or (ii) repurchase
such Mortgage Loan at the Repurchase Price; provided, however, that any such
substitution pursuant to clause (i) above shall not be effected prior to the
delivery to the Trustee or the Custodian, as applicable, of a Request for
Release substantially in the form of Exhibit J, and the delivery of the Mortgage
File to the Trustee or the Custodian, as applicable, for any such Substitute
Mortgage Loan. Notwithstanding the foregoing, a breach (i) which causes a
Mortgage Loan not to constitute a "qualified mortgage" within the meaning of
Section 860G(a)(3) of the Code or (ii) by the Responsible Party of any of the
representations and warranties set forth in clause (43), (44), (46), (48), (50),
(52), (53), (54), (55), (56), (57), (58), (59) or (69) of Schedule III, in each
case, will be deemed automatically to materially and adversely affect the value
of such Mortgage Loan and the interests of the Trustee and Certificateholders in
such Mortgage Loan. In the event that the Trustee receives notice of a breach by
the Responsible Party of any of the representations and warranties set forth in
clause (43), (44), (46), (48), (50), (52), (53), (54), (55), (56), (57), (58),
(59) or (69) of Schedule III, the Trustee shall give notice of such breach to
the Responsible Party and request the Responsible Party to repurchase the
Mortgage Loan at the Repurchase Price within sixty (60) days of the Responsible
Party receipt of such notice. The Responsible Party shall repurchase each such
Mortgage Loan within 60 days of the earlier of discovery or receipt of notice
with respect to each such Mortgage Loan, and in any case shall occur or shall be
deemed to occur on the last day of the applicable Prepayment Period preceding
the Distribution Date on which the Repurchase Price is to be distributed.

            (g) Within 90 days of the earlier of either discovery by or notice
to the Depositor of any breach of a representation or warranty set forth on
Schedule V hereto, the Depositor shall use its best efforts to promptly cure
such breach and, if such defect or breach cannot be remedied, the Depositor
shall purchase such Mortgage Loan at the Repurchase Price or substitute a
Substitute Mortgage Loan for such Mortgage Loan.

            (h) With respect to any Substitute Mortgage Loan or Loans
substituted by the Depositor or the Responsible Party, the Depositor or the
Responsible Party, as applicable, shall deliver to the Trustee or the Custodian,
as applicable, for the benefit of the Certificateholders the Mortgage Note, the
Mortgage, the related assignment of the Mortgage, and such other documents and
agreements as are required by Section 2.01, with the Mortgage Note endorsed and
the Mortgage assigned as required by Section 2.01. No substitution is permitted
to be made in any calendar month after the Determination Date for such month.
Scheduled Payments due with respect to Substitute Mortgage Loans in the Due
Period of substitution shall not be part of the Trust Fund and will be retained
by the Depositor or the Responsible Party, as applicable, on the next succeeding
Distribution Date. For the Due Period of substitution, distributions to
Certificateholders will include the Scheduled Payment due on any Deleted
Mortgage Loan for such Due Period and thereafter the Depositor or the
Responsible Party, as applicable, shall be entitled to retain all amounts
received in respect of such Deleted Mortgage Loan.

            (i) The Servicer, based upon information provided by the Depositor
or the Responsible Party, as applicable, shall amend the Mortgage Loan Schedule
for the benefit of the Certificateholders to reflect the removal of such Deleted
Mortgage Loan and the substitution of the Substitute Mortgage Loan or Loans and
the Servicer shall deliver the amended Mortgage Loan Schedule to the Trustee or
the Custodian, as applicable. Upon such substitution, the Substitute Mortgage
Loan or Loans shall be subject to the terms of this Agreement in all respects.
If such substitution is made by the Responsible Party, the Responsible Party
shall be deemed to have made with respect to such Substitute Mortgage Loan or
Loans, as of the date of substitution, the representations and warranties made
pursuant to Section 2.03(b) with respect to such Substitute Mortgage Loan or
Loans (and pursuant to Section 2.03(c) if the related Deleted Mortgage Loan is a
Group I Mortgage Loan), and if such substitution is made by the Depositor, the
Depositor shall be deemed to have made with respect to such Substitute Mortgage
Loan or Loans, as of the date of substitution, the representations and
warranties made pursuant to Sections 2.03(b) and (c) with respect to such
Substitute Mortgage Loan or Loans. Upon any such substitution and the deposit to
the Collection Account of the amount required to be deposited therein in
connection with such substitution as described in the following paragraph, the
Trustee or the Custodian, as applicable, shall release the Mortgage File held
for the benefit of the Certificateholders relating to such Deleted Mortgage Loan
to the Depositor or the Responsible Party, as applicable, and shall execute and
deliver at the direction of the Responsible Party or the Depositor, as
applicable, such instruments of transfer or assignment prepared by the Depositor
or the Responsible Party, as applicable, in each case without recourse, as shall
be necessary to vest title in the Depositor or the Responsible Party, as
applicable, of the Trustee's interest in any Deleted Mortgage Loan substituted
for pursuant to this Section 2.03.

            (j) For any month in which the Depositor or the Responsible Party
substitutes one or more Substitute Mortgage Loans for one or more Deleted
Mortgage Loans, the Servicer will determine the amount (if any) by which the
aggregate unpaid principal balance of all such Substitute Mortgage Loans as of
the date of substitution is less than the aggregate unpaid principal balance of
all such Deleted Mortgage Loans. The amount of such shortage, plus an amount
equal to the sum of (i) any accrued and unpaid interest on the Deleted Mortgage
Loans and (ii) all unreimbursed Servicing Advances with respect to such Deleted
Mortgage Loans (collectively, the "Substitution Adjustment Amount") shall be
deposited into the Collection Account by the Depositor or the Responsible Party,
as applicable, on or before the Distribution Account Deposit Date for the
Distribution Date in the month succeeding the calendar month during which the
related Mortgage Loan became required to be purchased or replaced hereunder.

             (k) In addition to such repurchase or substitution obligation, the
Responsible Party shall indemnify the Depositor and its Affiliates, the
Servicer, the Custodian, the Purchaser, the Trustee and the Trust and hold such
parties harmless against any losses, damages, penalties, fines, forfeitures,
reasonable and necessary legal fees and related costs, judgments and other costs
and expenses resulting from any claim, demand, defense or assertion based on or
grounded upon, or resulting from, a breach by the Responsible Party of any of
its representations and warranties or obligations contained in this Agreement.

            (l) In the event that the Depositor or the Responsible Party shall
have repurchased a Mortgage Loan, the Repurchase Price therefor shall be
deposited by the Servicer into the Collection Account pursuant to Section 3.10
on or before the Distribution Account Deposit Date for the Distribution Date in
the month following the month during which the Depositor or the Responsible
Party, as applicable, became obligated hereunder to repurchase or replace such
Mortgage Loan and upon such deposit of the Repurchase Price, and receipt of a
Request for Release in the form of Exhibit J hereto, the Trustee or the
Custodian, as applicable, shall release the related Custodial File held for the
benefit of the Certificateholders to such Person as directed by the Servicer,
and the Trustee shall execute and deliver at such Person's direction such
instruments of transfer or assignment prepared by such Person, in each case
without recourse, as shall be necessary to transfer title from the Trustee.

            (m) Any Mortgage Loan repurchased pursuant to this Section 2.03 will
be removed from the Trust Fund. The Servicer shall amend the Mortgage Loan
Schedule for the benefit of the Certificateholders to reflect the removal of any
Mortgage Loan repurchased, and the Servicer shall deliver the amended Mortgage
Loan Schedule to the Trustee and the Custodian.

            It is understood and agreed that the obligation of the Depositor or
the Responsible Party under this Agreement to cure, repurchase or substitute any
Mortgage Loan as to which a breach of a representation and warranty has occurred
and is continuing, together with any related indemnification obligations of the
Responsible Party set forth in Section 2.03(k), shall constitute the sole
remedies against such Person respecting such breach available to
Certificateholders, the Depositor (if applicable), the Servicer or the Trustee.

            The provisions of this Section 2.03 shall survive delivery of the
respective Custodial Files to the Trustee or the Custodian, as the case may be,
for the benefit of the Certificateholders.

            Section 2.04 Execution and Delivery of Certificates. The Trustee
acknowledges the transfer and assignment to it of the Trust Fund and,
concurrently with such transfer and assignment, has executed and delivered to or
upon the order of the Depositor, the Certificates in authorized denominations
evidencing directly or indirectly the entire ownership of the Trust Fund. The
Trustee agrees to hold the Trust Fund and exercise the rights referred to above
for the benefit of all present and future Holders of the Certificates.

            Section 2.05 REMIC Matters. The Preliminary Statement sets forth the
designations for federal income tax purposes of all interests created hereby.
The "Startup Day" for purposes of the REMIC Provisions shall be the Closing
Date. The "latest possible maturity date" is the Distribution Date occurring in
January 2035, which is the Distribution Date following the latest Mortgage Loan
maturity date.

            Section 2.06 Representations and Warranties of the Depositor. The
Depositor hereby represents, warrants and covenants to the Trustee and the
Servicer that as of the date of this Agreement or as of such date specifically
provided herein:

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

            (b) The Depositor has the corporate power and authority to convey
the Mortgage Loans and to execute, deliver and perform, and to enter into and
consummate the transactions contemplated by, this Agreement;

            (c) This Agreement has been duly and validly authorized, executed
and delivered by the Depositor, all requisite corporate action having been
taken, and, assuming the due authorization, execution and delivery hereof by the
other parties hereto, constitutes or will constitute the legal, valid and
binding agreement of the Depositor, enforceable against the Depositor in
accordance with its terms, except as such enforcement may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
relating to or affecting the rights of creditors generally, and by general
equity principles (regardless of whether such enforcement is considered in a
proceeding in equity or at law);

            (d) No consent, approval, authorization or order of or registration
or filing with, or notice to, any governmental authority or court is required
for the execution, delivery and performance of or compliance by the Depositor
with this Agreement or the consummation by the Depositor of any of the
transactions contemplated hereby, except as have been made on or prior to the
Closing Date;

            (e) None of the execution and delivery of this Agreement, the
consummation of the transactions contemplated hereby or thereby, or the
fulfillment of or compliance with the terms and conditions of this Agreement,
(i) conflicts or will conflict with or results or will result in a breach of, or
constitutes or will constitute a default or results or will result in an
acceleration under (A) the charter or bylaws of the Depositor, or (B) of any
term, condition or provision of any material indenture, deed of trust, contract
or other agreement or instrument to which the Depositor or any of its
subsidiaries is a party or by which it or any of its subsidiaries is bound; (ii)
results or will result in a violation of any law, rule, regulation, order,
judgment or decree applicable to the Depositor of any court or governmental

obligations under this Agreement, or the validity or enforceability of this
Agreement;

            (g) The Depositor is not in default with respect to any order or
decree of any court or any order, regulation or demand of any federal, state,
municipal or governmental agency that may materially and adversely affect its

            (h) Immediately prior to the transfer and assignment by the
Depositor to the Trustee on the Closing Date, the Depositor had good title to,
and was the sole owner of each Mortgage Loan, free of any interest of any other
Person, and the Depositor has transferred all right, title and interest in each
Mortgage Loan to the Trustee. The transfer of the Mortgage Note and the Mortgage
as and in the manner contemplated by this Agreement is sufficient either (i)
fully to transfer to the Trustee, for the benefit of the Certificateholders, all
right, title, and interest of the Depositor thereto as note holder and mortgagee
or (ii) to grant to the Trustee, for the benefit of the Certificateholders, the
security interest referred to in Section 10.04.

            It is understood and agreed that the representations, warranties and
covenants set forth in this Section 2.06 shall survive delivery of the
respective Custodial Files to the Trustee and shall inure to the benefit of the
Trustee.


                                  ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

            Section 3.01 Servicer to Service Mortgage Loans. (a) For and on
behalf of the Certificateholders, the Servicer shall service and administer the
Mortgage Loans in accordance with the terms of this Agreement and the respective
Mortgage Loans and, to the extent consistent with such terms, in the same manner
in which it services and administers similar mortgage loans for its own
portfolio, giving due consideration to customary and usual standards of practice
of mortgage lenders and loan servicers administering similar mortgage loans but
without regard to:

            (i) any relationship that the Servicer, any Subservicer or any
      Affiliate of the Servicer or any Subservicer may have with the related
      Mortgagor;

            (ii) the ownership or non-ownership of any Certificate by the
      Servicer or any Affiliate of the Servicer;

            (iii) the Servicer's obligation to make P&I Advances or Servicing
      Advances; or

            (iv) the Servicer's or any Subservicer's right to receive
      compensation for its services hereunder or with respect to any particular
      transaction.

            To the extent consistent with the foregoing, the Servicer shall seek
to maximize the timely and complete recovery of principal and interest on the
Mortgage Notes. Subject only to the above-described servicing standards and the
terms of this Agreement and of the respective Mortgage Loans, the Servicer shall
have full power and authority, acting alone or through Subservicers as provided
in Section 3.02, to do or cause to be done any and all things in connection with
such servicing and administration which it may deem necessary or desirable.
Without limiting the generality of the foregoing, the Servicer in its own name
or in the name of a Subservicer is hereby authorized and empowered by the
Trustee when the Servicer believes it appropriate in its best judgment in
accordance with Accepted Servicing Practices, to execute and deliver any and all
instruments of satisfaction or cancellation, or of partial or full release or
discharge, and all other comparable instruments, with respect to the Mortgage
Loans and the Mortgaged Properties and to institute foreclosure proceedings or
obtain a deed-in-lieu of foreclosure so as to convert the ownership of such
properties, and to hold or cause to be held title to such properties, on behalf
of the Trustee. The Servicer shall service and administer the Mortgage Loans in
accordance with applicable state and federal law and shall provide to the
Mortgagors any reports required to be provided to them thereby. The Servicer
covenants that its computer and other systems used in servicing the Mortgage
Loans operate in a manner such that the Servicer can service the Mortgage Loans
in accordance with the terms of this Pooling and Servicing Agreement. The
Servicer shall also comply in the performance of this Agreement with all
reasonable rules and requirements of each insurer under any standard hazard
insurance policy. Subject to Section 3.16, the Trustee shall execute, at the
written request of the Servicer, and furnish to the Servicer and any Subservicer
such documents provided to the Trustee as are necessary or appropriate to enable
the Servicer or any Subservicer to carry out their servicing and administrative
duties hereunder, and the Trustee hereby grants to the Servicer, and this
Agreement shall constitute, a power of attorney to carry out such duties
including a power of attorney in the form of Exhibit O hereto to take title to
Mortgaged Properties after foreclosure on behalf of the Trustee. The Trustee
shall execute a separate power of attorney in favor of the Servicer for the
purposes described herein to the extent necessary or desirable to enable the
Servicer to perform its duties hereunder. The Trustee shall not be liable for
the actions of the Servicer or any Subservicers under such powers of attorney.
Notwithstanding anything contained herein to the contrary, neither the Servicer
nor any Subservicer shall without the Trustee's consent: (i) initiate any
action, suit or proceeding solely under the Trustee's name without indicating
the Servicer's or Subservicer's, as applicable, representative capacity, or (ii)
take any action with the intent to, or which actually does cause, the Trustee to
be registered to do business in any state.

            (b) Subject to Section 3.09(b), in accordance with the standards of
the preceding paragraph, the Servicer shall advance or cause to be advanced
funds as necessary for the purpose of effecting the timely payment of taxes and
assessments on the Mortgaged Properties, which advances shall be Servicing
Advances reimbursable in the first instance from related collections from the
Mortgagors pursuant to Section 3.09(b), and further as provided in Section 3.11.
Any cost incurred by the Servicer or by Subservicers in effecting the timely
payment of taxes and assessments on a Mortgaged Property shall not be added to
the unpaid principal balance of the related Mortgage Loan, notwithstanding that
the terms of such Mortgage Loan so permit.

            (c) Notwithstanding anything in this Agreement to the contrary, the
Servicer may not make any future advances with respect to a Mortgage Loan
(except as provided in Section 4.01) and the Servicer shall not (i) permit any
modification with respect to any Mortgage Loan that would change the Mortgage
Rate, reduce or increase the principal balance (except for reductions resulting
from actual payments of principal) or change the final maturity date on such
Mortgage Loan (except for a reduction of interest payments resulting from the
application of the Servicemembers Civil Relief Act or any similar state
statutes) or (ii) permit any modification, waiver or amendment of any term of
any Mortgage Loan that would both (A) effect an exchange or reissuance of such
Mortgage Loan under Section 1001 of the Code (or final, temporary or proposed
Treasury regulations promulgated thereunder) and (B) cause either the Upper Tier
REMIC or the Lower Tier REMIC to fail to qualify as a REMIC under the Code or
the imposition of any tax on "prohibited transactions" or "contributions after
the startup date" under the REMIC Provisions, or (iii) except as provided in
Section 3.07(a), waive any Prepayment Charges.

            (d) The Servicer may delegate its responsibilities under this
Agreement; provided, however, that no such delegation shall release the Servicer
from the responsibilities or liabilities arising under this Agreement.

            (e) In the event that the Mortgage Loan Documents relating to any
Mortgage Loan contain provisions requiring the related Mortgagor to submit to
binding arbitration any disputes arising in connection with such Mortgage Loan,
the Servicer shall be entitled to waive any such provisions on behalf of the
Trust and to send written notice of such waiver to the related Mortgagor,
although the Mortgagor may still require arbitration of such disputes at its
option.

            Section 3.02 Subservicing Agreements between the Servicer and
Subservicers.(a) The Servicer may enter into subservicing agreements with
subservicers (each, a "Subservicer"), for the servicing and administration of
the Mortgage Loans ("Subservicing Agreements"). The Servicer shall, within a
reasonable period of time, give notice to the Trustee of any such Subservicing
Agreement. The Trustee shall not be required to review or consent to such
Subservicing Agreements and shall have no liability in connection therewith.

            (b) Each Subservicer shall be (i) authorized to transact business in
the state or states in which the related Mortgaged Properties it is to service
are situated, if and to the extent required by applicable law to enable the
Subservicer to perform its obligations hereunder and under the Subservicing
Agreement, (ii) an institution approved as a mortgage loan originator by the
Federal Housing Administration or an institution that has deposit accounts
insured by the FDIC and (iii) a Freddie Mac or Fannie Mae approved mortgage
servicer. Each Subservicing Agreement must impose on the Subservicer
requirements conforming to the provisions set forth in Section 3.08 and provide
for servicing of the Mortgage Loans consistent with the terms of this Agreement.
The Servicer will examine each Subservicing Agreement and will be familiar with
the terms thereof. The terms of any Subservicing Agreement will not be
inconsistent with any of the provisions of this Agreement. The Servicer and the
Subservicers may enter into and make amendments to the Subservicing Agreements
or enter into different forms of Subservicing Agreements; provided, however,
that any such amendments or different forms shall be consistent with and not
violate the provisions of this Agreement, and that no such amendment or
different form shall be made or entered into which could be reasonably expected
to be materially adverse to the interests of the Trustee, without the consent of
the Trustee. Any variation without the consent of the Trustee from the
provisions set forth in Section 3.08 relating to insurance or priority
requirements of Subservicing Accounts, or credits and charges to the
Subservicing Accounts or the timing and amount of remittances by the
Subservicers to the Servicer, are conclusively deemed to be inconsistent with
this Agreement and therefore prohibited. The Servicer shall deliver to the
Trustee and the Depositor copies of all Subservicing Agreements, and any
amendments or modifications thereof, promptly upon the Servicer's execution and
delivery of such instruments.

            (c) As part of its servicing activities hereunder, the Servicer
(except as otherwise provided in the last sentence of this paragraph), for the
benefit of the Trustee, shall enforce the obligations of each Subservicer under
the related Subservicing Agreement, including, without limitation, any
obligation to make advances in respect of delinquent payments as required by a
Subservicing Agreement. Such enforcement, including, without limitation, the
legal prosecution of claims, termination of Subservicing 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 Servicer, in its good faith business
judgment, would require were it the owner of the related Mortgage Loans. The
Servicer shall pay the costs of such enforcement at its own expense, and shall
be reimbursed therefor only (i) from a general recovery resulting from such
enforcement, to the extent, if any, that such recovery exceeds all amounts due
in respect of the related Mortgage Loans or (ii) from a specific recovery of
costs, expenses or attorneys' fees against the party against whom such
enforcement is directed.

            Section 3.03 Successor Subservicers. The Servicer shall be entitled
to terminate any Subservicing Agreement and the rights and obligations of any
Subservicer pursuant to any Subservicing Agreement in accordance with the terms
and conditions of such Subservicing Agreement. In the event of termination of
any Subservicer, all servicing obligations of such Subservicer shall be assumed
simultaneously by the Servicer without any act or deed on the part of such
Subservicer or the Servicer, and the Servicer either shall service directly the
related Mortgage Loans or shall enter into a Subservicing Agreement with a
successor Subservicer which qualifies under Section 3.02.

            Any Subservicing Agreement shall include the provision that such
agreement may be immediately terminated by the Depositor or the Trustee without
fee, in accordance with the terms of this Agreement, in the event that the
Servicer shall, for any reason, no longer be the Servicer (including termination
due to an Event of Default).

            Section 3.04 Liability of the Servicer. Notwithstanding any
Subservicing Agreement, any of the provisions of this Agreement relating to
agreements or arrangements between the Servicer and a Subservicer or reference
to actions taken through a Subservicer or otherwise, the Servicer shall remain
obligated and primarily liable to the Trustee for the servicing and
administering of the Mortgage Loans in accordance with the provisions of Section
3.01 without diminution of such obligation or liability by virtue of such
Subservicing Agreements or arrangements or by virtue of indemnification from the
Subservicer and to the same extent and under the same terms and conditions as if
the Servicer alone were servicing and administering the Mortgage Loans. The
Servicer shall be entitled to enter into any agreement with a Subservicer for
indemnification of the Servicer by such Subservicer and nothing contained in
this Agreement shall be deemed to limit or modify such indemnification.

            Section 3.05 No Contractual Relationship between Subservicers and
the Trustee. Any Subservicing Agreement that may be entered into and any
transactions or services relating to the Mortgage Loans involving a Subservicer
in its capacity as such shall be deemed to be between the Subservicer and the
Servicer alone, and the Trustee (or any successor Servicer) shall not be deemed
a party thereto and shall have no claims, rights, obligations, duties or
liabilities with respect to the Subservicer except as set forth in Section 3.06.
The Servicer shall be solely liable for all fees owed by it to any Subservicer,
irrespective of whether the Servicer's compensation pursuant to this Agreement
is sufficient to pay such fees.

            Section 3.06 Assumption or Termination of Subservicing Agreements by
Trustee. In the event the Servicer at any time shall for any reason no longer be
the Servicer (including by reason of the occurrence of an Event of Default), the
Trustee, or its designee or the successor Servicer if the successor is not the
Trustee, shall thereupon assume all of the rights and obligations of the
Servicer under each Subservicing Agreement that the Servicer may have entered
into, with copies thereof provided to the Trustee or the successor Servicer if
the successor is not the Trustee, prior to the Trustee or the successor Servicer
if the successor is not the Trustee, assuming such rights and obligations,
unless the Trustee elects to terminate any Subservicing Agreement in accordance
with its terms as provided in Section 3.03.

            Upon such assumption, the Trustee, its designee or the successor
Servicer shall be deemed, subject to Section 3.03, to have assumed all of the
Servicer's interest therein and to have replaced the Servicer as a party to each
Subservicing Agreement to the same extent as if each Subservicing Agreement had
been assigned to the assuming party, except that (i) the Servicer shall not
thereby be relieved of any liability or obligations under any Subservicing
Agreement that arose before it ceased to be the Servicer and (ii) none of the
Depositor, the Trustee, their designees or any successor Servicer shall be
deemed to have assumed any liability or obligation of the Servicer that arose
before it ceased to be the Servicer.

            The Servicer at its expense shall, upon request of the Trustee, its
designee or the successor Servicer deliver to the assuming party all documents
and records relating to each Subservicing Agreement and the Mortgage Loans then
being serviced and an accounting of amounts collected and held by or on behalf
of it, and otherwise use its best efforts to effect the orderly and efficient
transfer of the Subservicing Agreements to the assuming party.

            Section 3.07 Collection of Certain Mortgage Loan Payments. (a) The
Servicer shall make reasonable efforts to collect all payments called for under
the terms and provisions of the Mortgage Loans, and shall, to the extent such
procedures shall be consistent with this Agreement and the terms and provisions
of any applicable Insurance Policies, follow such collection procedures as it
would follow with respect to mortgage loans comparable to the Mortgage Loans and
held for its own account. Consistent with the foregoing and Accepted Servicing
Practices, the Servicer may (i) waive any late payment charge or, if applicable,
any penalty interest, or (ii) extend the due dates for the Scheduled Payments
due on a Mortgage Note for a period of not greater than 180 days; provided, that
any extension pursuant to clause (ii) above shall not affect the amortization
schedule of any Mortgage Loan for purposes of any computation hereunder, except
as provided below. In the event of any such arrangement pursuant to clause (ii)
above, the Servicer shall make timely advances on such Mortgage Loan during such
extension pursuant to Section 4.01 and in accordance with the amortization
schedule of such Mortgage Loan without modification thereof by reason of such
arrangements, subject to Section 4.01(d) pursuant to which the Servicer shall
not be required to make any such advances that are Nonrecoverable P&I Advances.
Notwithstanding the foregoing, the Servicer may waive, in whole or in part, a
Prepayment Charge only under the following circumstances: (i) such waiver
relates to a default or a reasonably foreseeable default and would, in the
reasonable judgment of the Servicer, maximize recovery of total proceeds taking
into account the value of such Prepayment Charge and the related Mortgage Loan,
(ii) such Prepayment Charge is not permitted to be collected by applicable
federal, state or local law or regulation or (iii) the collection of such
Prepayment Charge would be considered "predatory" pursuant to written guidance
published or issued by any applicable federal, state or local regulatory
authority acting in its official capacity and having jurisdiction over such
matters. If a Prepayment Charge is waived other than as permitted by the prior
sentence, then the Servicer is required to pay the amount of such waived
Prepayment Charge, for the benefit of the Holders of the Class P Certificates,
by depositing such amount into the Collection Account together with and at the
time that the amount prepaid on the related Mortgage Loan is required to be
deposited into the Collection Account; provided, however, that the Servicer
shall not have an obligation to pay the amount of any uncollected Prepayment
Charge if the failure to collect such amount is the direct result of inaccurate
or incomplete information on the Mortgage Loan Schedule in effect at such time.

            (b) (i) The Trustee shall establish and maintain the Excess Reserve
Fund Account, on behalf of the Class X Certificateholders, to receive any Basis
Risk Payment and any Interest Rate Cap Payment and to secure their limited
recourse obligation to pay to the LIBOR Certificateholders Basis Risk
CarryForward Amounts.

            (ii) On each Distribution Date, the Trustee shall deposit the amount
      of any Basis Risk Payment and any Interest Rate Cap Payment for such date
      into the Excess Reserve Fund Account.

            (c) (i) On each Distribution Date on which there exists a Basis Risk
CarryForward Amount on any Class of Certificates, the Trustee shall (1) withdraw
from the Distribution Account and deposit in the Excess Reserve Fund Account, as
set forth in Section 4.02(a)(iii)(S), the lesser of (x) the Class X
Distributable Amount (without regard to the reduction in the definition thereof
with respect to the Basis Risk Payment) (to the extent remaining after the
distributions specified in Sections 4.02(a)(iii)(A)-(R)) and (y) the aggregate
Basis Risk CarryForward Amounts for such Distribution Date and (2) withdraw from
the Excess Reserve Fund Account amounts necessary to pay to such Class or
Classes of Certificates the Basis Risk CarryForward Amount. Such payments shall
be allocated to those Classes on a pro rata basis based upon the amount of Basis
Risk CarryForward Amount owed to each such Class and shall be paid in the
priority set forth in Sections 4.02(a)(iii)(T)-(U).

            (ii) The Trustee shall account for the Excess Reserve Fund Account
      as an asset of a grantor trust under subpart E, Part I of the subchapter J
      of the Code and not as an asset of any REMIC created pursuant to this
      Agreement. The beneficial owners of the Excess Reserve Fund Account are
      the Class X Certificateholders. For all federal tax purposes, amounts
      transferred by the Upper Tier REMIC to the Excess Reserve Fund Account
      shall be treated as distributions by the Trustee to the Class X
      Certificateholders.

            (iii) Any Basis Risk CarryForward Amounts paid by the Trustee to the
      LIBOR Certificateholders shall be accounted for by the Trustee as amounts
      paid first to the Holders of the Class X Certificates and then to the
      respective Class or Classes of LIBOR Certificates. In addition, the
      Trustee shall account for the LIBOR Certificateholders' rights to receive
      payments of Basis Risk CarryForward Amounts as rights in a limited
      recourse interest rate cap contract written by the Class X
      Certificateholders in favor of the LIBOR Certificateholders.

            (iv) Notwithstanding any provision contained in this Agreement, the
      Trustee shall not be required to make any payments from the Excess Reserve
      Fund Account except as expressly set forth in this Section 3.07(c) and
      Sections 4.02(a)(iii)(T)-(V).

            (d) The Trustee shall establish and maintain the Distribution
Account on behalf of the Certificateholders. The Depositor shall cause to be
deposited into the Distribution Account on the Closing Date the Closing Date
Deposit Amount. The Trustee shall, promptly upon receipt, deposit in the
Distribution Account and retain therein the following:

            (i) the aggregate amount remitted by the Servicer to the Trustee
      pursuant to Section 3.11;

            (ii) any amount deposited by the Servicer pursuant to Section
      3.12(b) in connection with any losses on Permitted Investments; and

            (iii) any other amounts deposited hereunder which are required to be
      deposited in the Distribution Account.

            In the event that the Servicer shall remit any amount not required
to be remitted, it may at any time direct the Trustee in writing to withdraw
such amount from the Distribution Account, any provision herein to the contrary
notwithstanding. Such direction may be accomplished by delivering notice to the
Trustee which describes the amounts deposited in error in the Distribution
Account. All funds deposited in the Distribution Account shall be held by the
Trustee in trust for the Certificateholders until disbursed in accordance with
this Agreement or withdrawn in accordance with Section 4.02.

            (e) The Trustee may invest the funds in the Distribution Account, in
one or more Permitted Investments, in accordance with Section 3.12. The Servicer
shall direct the Trustee to withdraw from the Distribution Account and to remit
to the Servicer no less than monthly, all income and gain realized from the
investment of the portion of funds deposited in the Distribution Account by the
Servicer (except during the Trustee Float Period). The Trustee may withdraw from
the Distribution Account any income or gain earned from the investment of funds
deposited therein during the Trustee Float Period for its own benefit.

            (f) The Servicer shall give notice to the Trustee, each Rating
Agency and the Depositor of any proposed change of the location of the
Collection Account within a reasonable period of time prior to any change
thereof.

            (g) In order to comply with its duties under the USA Patriot Act of
2001, the Trustee shall obtain and verify certain information and documentation
from the other parties to this Agreement including, but not limited to, each
such party's name, address, and other identifying information.

            (h) On or prior to the Determination Date, the Custodian shall
deliver an invoice to the Trustee, setting forth the amount of the Custodian Fee
for the related Distribution Date. The Trustee shall calculate the Custodian Fee
Rate for such Distribution Date, based upon the Custodian Fee as set forth in
such invoice. On each Distribution Date, the Trustee shall remit the Custodian
Fee to the Custodian from the Distribution Account.

            Section 3.08 Subservicing Accounts. In those cases where a
Subservicer is servicing a Mortgage Loan pursuant to a Subservicing Agreement,
the Subservicer will be required to establish and maintain one or more accounts
(collectively, the "Subservicing Account"). The Subservicing Account shall be an
Eligible Account and shall otherwise be acceptable to the Servicer. The
Subservicer shall deposit in the clearing account (which account must be an
Eligible Account) in which it customarily deposits payments and collections on
mortgage loans in connection with its mortgage loan servicing activities on a
daily basis, and in no event more than one Business Day after the Subservicer's
receipt thereof, all proceeds of Mortgage Loans received by the Subservicer less
its servicing compensation to the extent permitted by the Subservicing
Agreement, and shall thereafter deposit such amounts in the Subservicing
Account, in no event more than two Business Days after the deposit of such funds
into the clearing account. The Subservicer shall thereafter deposit such
proceeds in the Collection Account or remit such proceeds to the Servicer for
deposit in the Collection Account not later than two Business Days after the
deposit of such amounts in the Subservicing Account. For purposes of this
Agreement, the Servicer shall be deemed to have received payments on the
Mortgage Loans when the Subservicer receives such payments.

             Section 3.09 Collection of Taxes, Assessments and Similar Items;
Escrow Accounts. (a) The Servicer shall enforce the obligations under each
paid-in-full, life-of-the-loan tax service contract in effect with respect to
each First Lien Mortgage Loan (each, a "Tax Service Contract"). Each Tax Service
Contract shall be assigned to the Trustee, or a successor Servicer at the
Servicer's expense in the event that the Servicer is terminated as Servicer of
the related Mortgage Loan.

            (b) To the extent that the services described in this paragraph (b)
are not otherwise provided pursuant to the Tax Service Contracts described in
paragraph (a) above, the Servicer undertakes to perform such functions. To the
extent the related Mortgage provides for Escrow Payments, the Servicer shall
establish and maintain, or cause to be established and maintained, one or more
accounts (the "Escrow Accounts"), which shall be Eligible Accounts. The Servicer
shall deposit in the clearing account (which account must be an Eligible
Account) in which it customarily deposits payments and collections on mortgage
loans in connection with its mortgage loan servicing activities on a daily
basis, and in no event more than one Business Day after the Servicer's receipt
thereof, all collections from the Mortgagors (or related advances from
Subservicers) for the payment of taxes, assessments, hazard insurance premiums
and comparable items for the account of the Mortgagors ("Escrow Payments")
collected on account of the Mortgage Loans and shall thereafter deposit such
Escrow Payments in the Escrow Accounts, in no event more than two Business Days
after the deposit of such funds in the clearing account, for the purpose of
effecting the payment of any such items as required under the terms of this
Agreement. Withdrawals of amounts from an Escrow Account may be made only to (i)
effect payment of taxes, assessments, hazard insurance premiums, and comparable
items; (ii) reimburse the Servicer (or a Subservicer to the extent provided in
the related Subservicing Agreement) out of related collections for any advances
made pursuant to Section 3.01 (with respect to taxes and assessments) and
Section 3.13 (with respect to hazard insurance); (iii) refund to Mortgagors any
sums as may be determined to be overages; (iv) pay interest, if required and as
described below, to Mortgagors on balances in the Escrow Account; (v) clear and
terminate the Escrow Account at the termination of the Servicer's obligations
and responsibilities in respect of the Mortgage Loans under this Agreement; or
(vi) recover amounts deposited in error. As part of its servicing duties, the
Servicer or Subservicers shall pay to the Mortgagors interest on funds in Escrow
Accounts, to the extent required by law and, to the extent that interest earned
on funds in the Escrow Accounts is insufficient, to pay such interest from its
or their own funds, without any reimbursement therefor. To the extent that a
Mortgage does not provide for Escrow Payments, the Servicer shall determine
whether any such payments are made by the Mortgagor in a manner and at a time
that avoids the loss of the Mortgaged Property due to a tax sale or the
foreclosure of a tax lien. The Servicer assumes full responsibility for the
payment of all such bills within such time and shall effect payments of all such
bills irrespective of the Mortgagor's faithful performance in the payment of
same or the making of the Escrow Payments and shall make advances from its own
funds to effect such payments; provided, however, that such advances are deemed
to be Servicing Advances.

            Section 3.10 Collection Account. (a) On behalf of the Trustee, the
Servicer shall establish and maintain, or cause to be established and
maintained, one or more separate Eligible Accounts (such account or accounts,
the "Collection Account"), held in trust for the benefit of the Trustee on
behalf of the Certificateholders. On behalf of the Trustee, the Servicer shall
deposit or cause to be deposited in the clearing account (which account must be
an Eligible Account) in which it customarily deposits payments and collections
on mortgage loans in connection with its mortgage loan servicing activities on a
daily basis, and in no event more than one Business Day after the Servicer's
receipt thereof, and shall thereafter deposit in the Collection Account, in no
event more than two Business Days after the deposit of such funds into the
clearing account, as and when received or as otherwise required hereunder, the
following payments and collections received or made by it subsequent to the
Cut-off Date (other than in respect of principal or interest on the related
Mortgage Loans due on or before the Cut-off Date), or payments (other than
Principal Prepayments) received by it on or prior to the Cut-off Date but
allocable to a Due Period subsequent thereto:

            (i) all payments on account of principal, including Principal
      Prepayments, on the Mortgage Loans;

            (ii) all payments on account of interest (net of the related
      Servicing Fee) on each Mortgage Loan;

            (iii) all Insurance Proceeds and Condemnation Proceeds to the extent
      such Insurance Proceeds and Condemnation Proceeds are not to be applied to
      the restoration of the related Mortgaged Property or released to the
      related Mortgagor in accordance with the express requirements of law or in
      accordance with Accepted Servicing Practices and Liquidation Proceeds;

            (iv) any amounts required to be deposited pursuant to Section 3.12
      in connection with any losses realized on Permitted Investments with
      respect to funds held in the Collection Account;

            (v) any amounts required to be deposited by the Servicer pursuant to
      the second paragraph of Section 3.13(a) in respect of any blanket policy
      deductibles;

            (vi) all proceeds of any Mortgage Loan repurchased or purchased in
      accordance with this Agreement; and

            (vii) all Prepayment Charges collected or paid (pursuant to Section
      3.07(a)) by the Servicer.

            The foregoing requirements for deposit in the Collection Account
shall be exclusive, it being understood and agreed that, without limiting the
generality of the foregoing, payments in the nature of late payment charges, NSF
fees, reconveyance fees, assumption fees and other similar fees and charges need
not be deposited by the Servicer in the Collection Account and shall, upon
collection, belong to the Servicer as additional compensation for its servicing
activities. In the event the Servicer shall deposit in the Collection Account
any amount not required to be deposited therein, it may at any time withdraw
such amount from the Collection Account, any provision herein to the contrary
notwithstanding.

            (b) Funds in the Collection Account may be invested in Permitted
Investments in accordance with the provisions set forth in Section 3.12. The
Servicer shall give notice to the Trustee and the Depositor of the location of
the Collection Account maintained by it when established and prior to any change
thereof in accordance with Section 3.07(f).

            Section 3.11 Withdrawals from the Collection Account. (a) The
Servicer shall, from time to time, make withdrawals from the Collection Account
for any of the following purposes or as described in Section 4.01:

            (i) on or prior to each Remittance Date, to remit to the Trustee (A)
      the Trustee Fee with respect to such Distribution Date and (B) all
      Available Funds in respect of the related Distribution Date together with
      all amounts representing Prepayment Charges from the Mortgage Loans
      received during the related Prepayment Period;

            (ii) to reimburse the Servicer for P&I Advances, but only to the
      extent of amounts received which represent Late Collections (net of the
      related Servicing Fees) of Scheduled Payments on Mortgage Loans with
      respect to which such P&I Advances were made in accordance with the
      provisions of Section 4.01 (the Servicer's right for recovery or
      reimbursement has priority over the Trust as stated in the definition of
      "Available Funds");

            (iii) to pay the Servicer or any Subservicer (a) any unpaid
      Servicing Fees or (b) any unreimbursed Servicing Advances with respect to
      each Mortgage Loan serviced by the Servicer or Subservicer, but only to
      the extent of any Late Collections, Liquidation Proceeds, Condemnation
      Proceeds, Insurance Proceeds or other amounts as may be collected by the
       Servicer from a Mortgagor, or otherwise received with respect to such
      Mortgage Loan (or the related REO Property) (the Servicer's right for
      recovery or reimbursement has priority over the Trust as stated in the
      definition of "Available Funds");

            (iv) to pay to the Servicer as servicing compensation (in addition
      to the Servicing Fee) on each Remittance Date any interest or investment
      income earned on funds deposited in the Collection Account;

            (v) to pay to the Responsible Party or the Depositor, as applicable,
      with respect to each Mortgage Loan that has previously been repurchased or
      replaced pursuant to this Agreement, all amounts received thereon
      subsequent to the date of purchase or substitution, as further described
      herein;

            (vi) to reimburse the Servicer for (A) any P&I Advance or Servicing
      Advance previously made which the Servicer has determined to be a
      Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance in
      accordance with the provisions of Section 4.01 and (B) any unpaid
      Servicing Fees related to any Second Lien Mortgage Loan to the extent not
      recoverable from Liquidation Proceeds, Insurance Proceeds or other amounts
       received with respect to the related Second Lien Mortgage Loan under
      Section 3.11(a)(iii) (the Servicer's right for recovery or reimbursement
      has priority over the Trust as stated in the definition of "Available
      Funds");

            (vii) to pay, or to reimburse the Servicer for advances in respect
      of, expenses incurred in connection with any Mortgage Loan serviced by the
      Servicer pursuant to Section 3.15 (the Servicer's right for recovery or
      reimbursement has priority over the Trust as stated in the definition of
      "Available Funds");

            (viii) to reimburse the Servicer or the Depositor for expenses
      incurred by or reimbursable to the Servicer or the Depositor, as the case
      may be, pursuant to Section 6.03 (the Servicer's right for recovery or
      reimbursement has priority over the Trust as stated in the definition of
      "Available Funds");

            (ix) to reimburse the Servicer or the Trustee, as the case may be,
      for expenses reasonably incurred in respect of the breach or defect giving
      rise to the repurchase obligation of the Responsible Party or the
      Depositor, as applicable, that were included in the Repurchase Price of
      the Mortgage Loan, including any expenses arising out of the enforcement
      of the repurchase obligation, to the extent not otherwise paid pursuant to
      the terms hereof (the Servicer's right for recovery or reimbursement has
      priority over the Trust as stated in the definition of "Available Funds");

            (x) to withdraw any amounts deposited in the Collection Account in
      error;

            (xi) to withdraw any amounts held in the Collection Account and not
      required to be remitted to the Trustee on the Remittance Date occurring in
      the month in which such amounts are deposited into the Collection Account,
      to reimburse the Servicer for unreimbursed P&I Advances;

            (xii) to invest funds in Permitted Investments in accordance with
      Section 3.12; and

            (xiii) to clear and terminate the Collection Account upon
      termination of this Agreement.

            (b) The Servicer shall keep and maintain separate accounting, on a
Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Collection Account, to the extent held by or on behalf of
it, pursuant to subclauses (a)(ii), (iii), (v), (vi), (vii), (viii) and (ix)
above. The Servicer shall provide written notification (as set forth in Section
4.01(d)) to the Trustee, on or prior to the next succeeding Remittance Date,
upon making any withdrawals from the Collection Account pursuant to subclause
(a)(vi) above.

            Section 3.12 Investment of Funds in the Collection Account and the
Distribution Account. (a) The Servicer may invest the funds in the Collection
Account in one or more Permitted Investments bearing interest or sold at a
discount, and maturing, unless payable on demand, no later than the Business Day
immediately preceding the date on which such funds are required to be withdrawn
from such account pursuant to this Agreement. The Trustee may (but is not
obligated to) invest funds in the Distribution Account during the Trustee Float
Period, and, with respect to the portion of funds in the Distribution Account
deposited by the Servicer, shall (except during the Trustee Float Period) invest
such funds in the Distribution Account at the direction of the Servicer (for
purposes of this Section 3.12, such Accounts are referred to as an "Investment
Account"), in one or more Permitted Investments bearing interest or sold at a
discount, and maturing, unless payable on demand, no later than the Business Day
immediately preceding the date on which such funds are required to be withdrawn
from such account pursuant to this Agreement; provided, however, that the
Trustee shall have no obligation to invest funds deposited into the Distribution
Account by the Servicer on the Remittance Date later than 10:00 a.m. (Pacific
Standard Time). If no investment instruction is given in a timely manner, the
Trustee shall hold the funds in the Distribution Account uninvested. All such
Permitted Investments shall be held to maturity, unless payable on demand. Any
investment of funds in an Investment Account (other than investments made during
the Trustee Float Period) shall be made in the name of the Servicer. The
Servicer shall be entitled to sole possession (except with respect to investment
direction of funds and any income and gain realized on any investment in the
Distribution Account during the Trustee Float Period) over each such investment,
and any certificate or other instrument evidencing any such investment shall be
delivered directly to the Servicer, or with respect to investments during the
Trustee Float Period, the Trustee or its agent (with a copy to the Trustee or
its agent if related to investment of funds in the Distribution Account not
during the Trustee Float Period), together with any document of transfer
necessary to transfer title to such investment to the Servicer, or with respect
to investments during the Trustee Float Period, the Trustee or its agent. In the
event amounts on deposit in an Investment Account are at any time invested in a
Permitted Investment payable on demand, the Servicer, or with respect to
investments during the Trustee Float Period, the Trustee may:

            (x)    consistent with any notice required to be given thereunder,
                  demand that payment thereon be made on the last day such
                  Permitted Investment may otherwise mature hereunder in an
                  amount equal to the lesser of (1) all amounts then payable
                  thereunder and (2) the amount required to be withdrawn on such
                  date; and

            (y)    demand payment of all amounts due thereunder that such
                  Permitted Investment would not constitute a Permitted
                  Investment in respect of funds thereafter on deposit in an
                  Investment Account.

            (b) All income and gain realized from the investment of funds
deposited in the Collection Account, held by or on behalf of the Servicer, shall
be for the benefit of the Servicer and shall be subject to its withdrawal in the
manner set forth in Section 3.11. The Servicer shall deposit in the Collection
Account the amount of any loss of principal incurred in respect of any such
Permitted Investment made with funds in such accounts immediately upon
realization of such loss.

            (c) All income and gain realized from the investment of the portion
of funds deposited in the Distribution Account by the Servicer and held by the
Trustee, shall be for the benefit of the Servicer (except for any income or gain
realized from the investment of funds on deposit in the Distribution Account
during the Trustee Float Period, which shall be for the benefit of the Trustee)
and shall be subject to the Trustee's withdrawal in the manner set forth in
Section 3.07(e). The Servicer shall deposit in the Distribution Account (except
with respect to losses incurred during the Trustee Float Period) the amount of
any loss of principal incurred in respect of any such Permitted Investment made
with funds in such accounts immediately upon realization of such loss.

            (d) Except as otherwise expressly provided in this Agreement, if any
default occurs in the making of a payment due under any Permitted Investment, or
if a default occurs in any other performance required under any Permitted
Investment, the Trustee shall take such action as may be appropriate to enforce
such payment or performance, including the institution and prosecution of
appropriate proceedings.

            (e) The Trustee shall not be liable for the amount of any loss
incurred with respect of any investment or lack of investment of funds held in
any Investment Account or the Distribution Account (except that if any such
losses are incurred during the Trustee Float Period, the Trustee shall be
responsible for reimbursing the Trust for such loss immediately upon realization
of such loss) if made in accordance with this Section 3.12.

            (f) The Trustee or its Affiliates are permitted to receive
additional compensation that could be deemed to be in the Trustee's economic
self-interest for (i) serving as investment adviser, administrator, shareholder,
servicing agent, custodian or sub-custodian with respect to certain of the
Permitted Investments, (ii) using Affiliates to effect transactions in certain
Permitted Investments and (iii) effecting transactions in certain Permitted
Investments. Such compensation shall not be considered an amount that is
reimbursable or payable pursuant to this Agreement.

            Section 3.13 Maintenance of Hazard Insurance and Errors and
Omissions and Fidelity Coverage. (a) The Servicer shall cause to be maintained
for each Mortgage Loan fire insurance with extended coverage on the related
Mortgaged Property in an amount which is at least equal to the least of (i) the
outstanding principal balance of such Mortgage Loan, (ii) the amount necessary
to fully compensate for any damage or loss to the improvements that are a part
of such property on a replacement cost basis and (iii) the maximum insurable
value of the improvements which are a part of such Mortgaged Property, in each
case in an amount not less than such amount as is necessary to avoid the
application of any coinsurance clause contained in the related hazard insurance
policy. The Servicer shall also cause to be maintained fire insurance with
extended coverage on each REO Property in an amount which is at least equal to
the lesser of (i) the maximum insurable value of the improvements which are a
part of such property and (ii) the outstanding principal balance of the related
Mortgage Loan at the time it became an REO Property, plus accrued interest at
the Mortgage Rate and related Servicing Advances. The Servicer will comply in
the performance of this Agreement with all reasonable rules and requirements of
each insurer under any such hazard policies. Any amounts to be collected by the
Servicer under any such policies (other than amounts to be applied to the
restoration or repair of the property subject to the related Mortgage or amounts
to be released to the Mortgagor in accordance with the procedures that the
Servicer would follow in servicing loans held for its own account, subject to
the terms and conditions of the related Mortgage and Mortgage Note) shall be
deposited in the Collection Account, subject to withdrawal pursuant to Section
3.11. Any cost incurred by the Servicer in maintaining any such insurance shall
not, for the purpose of calculating distributions to the Trustee, be added to
the unpaid principal balance of the related Mortgage Loan, notwithstanding that
the terms of such Mortgage Loan so permit. It is understood and agreed that no
earthquake or other additional insurance is to be required of any Mortgagor
other than pursuant to such applicable laws and regulations as shall at any time
be in force and as shall require such additional insurance. If the Mortgaged
Property or REO Property is at any time in an area identified in the Federal
Register by the Federal Emergency Management Agency as having special flood
hazards and flood insurance has been made available, the Servicer will cause to
be maintained a flood insurance policy in respect thereof. Such flood insurance
shall be in an amount equal to the lesser of (i) the unpaid principal balance of
the related Mortgage Loan and (ii) the maximum amount of such insurance
available for the related Mortgaged Property under the national flood insurance
program (assuming that the area in which such Mortgaged Property is located is
participating in such program).

            In the event that the Servicer shall obtain and maintain a blanket
policy with an insurer either (i) acceptable to Fannie Mae or Freddie Mac or
(ii) having a General Policy Rating of A:X or better from Best's (or such other
rating that is comparable to such rating) insuring against hazard losses on all
of the Mortgage Loans, it shall conclusively be deemed to have satisfied its
obligations as set forth in the first two sentences of this Section 3.13, it
being understood and agreed that such policy may contain a deductible clause, in
which case the Servicer shall, in the event that there shall not have been
maintained on the related Mortgaged Property or REO Property a policy complying
with the first two sentences of this Section 3.13, and there shall have been one
or more losses which would have been covered by such policy, deposit to the
Collection Account from its own funds the amount not otherwise payable under the
blanket policy because of such deductible clause. In connection with its
activities as administrator and servicer of the Mortgage Loans, the Servicer
agrees to prepare and present, on behalf of itself and the Trustee claims under
any such blanket policy in a timely fashion in accordance with the terms of such
policy.

            (b) The Servicer shall keep in force during the term of this
Agreement a policy or policies of insurance covering errors and omissions for
failure in the performance of the Servicer's obligations under this Agreement,
which policy or policies shall be in such form and amount that would meet the
requirements of Fannie Mae or Freddie Mac if it were the purchaser of the
Mortgage Loans, unless the Servicer has obtained a waiver of such requirements
from Fannie Mae or Freddie Mac. The Servicer shall also maintain a fidelity bond
in the form and amount that would meet the requirements of Fannie Mae or Freddie
Mac, unless the Servicer has obtained a waiver of such requirements from Fannie
Mae or Freddie Mac. The Servicer shall provide the Trustee upon request with
copies of any such insurance policies and fidelity bond. The Servicer shall be
deemed to have complied with this provision if an Affiliate of the Servicer has
such errors and omissions and fidelity bond coverage and, by the terms of such
insurance policy or fidelity bond, the coverage afforded thereunder extends to
the Servicer. Any such errors and omissions policy and fidelity bond shall by
its terms not be cancelable without thirty days' prior written notice to the
Trustee. The Servicer shall also cause each Subservicer to maintain a policy of
insurance covering errors and omissions and a fidelity bond which would meet
such requirements.

            Section 3.14 Enforcement of Due-On-Sale Clauses; Assumption
Agreements. The Servicer will, to the extent it has knowledge of any conveyance
or prospective conveyance of any Mortgaged Property by any Mortgagor (whether by
absolute conveyance or by contract of sale, and whether or not the Mortgagor
remains or is to remain liable under the Mortgage Note and/or the Mortgage),
exercise its rights to accelerate the maturity of such Mortgage Loan under the
"due-on-sale" clause, if any, applicable thereto; provided, however, that the
Servicer shall not be required to take such action if, in its sole business
judgment, the Servicer believes it is not in the best interests of the Trust
Fund and shall not exercise any such rights if prohibited by law from doing so.
If the Servicer reasonably believes it is unable under applicable law to enforce
such "due-on-sale" clause or if any of the other conditions set forth in the
proviso to the preceding sentence apply, the Servicer shall enter into either
(i) an assumption and modification agreement from or with the person to whom
such property has been conveyed or is proposed to be conveyed, pursuant to which
such person becomes liable under the Mortgage Note and, to the extent permitted
by applicable state law, the Mortgagor remains liable thereon or (ii) a
substitution agreement as provided in the succeeding sentence. The Servicer is
also authorized to enter into a substitution of liability agreement with such
person, pursuant to which the original Mortgagor is released from liability and
such person is substituted as the Mortgagor and becomes liable under the
Mortgage Note, provided, that no such substitution shall be effective unless
such person satisfies the underwriting criteria of the Servicer and such
substitution is in the best interest of the Certificateholders as determined by
the Servicer. In connection with any assumption, modification or substitution,
the Servicer shall apply such underwriting standards and follow such practices
and procedures as shall be normal and usual in its general mortgage servicing
activities and as it applies to other mortgage loans owned solely by it. The
Servicer shall not take or enter into any assumption and modification agreement,
however, unless (to the extent practicable in the circumstances) it shall have
received confirmation, in writing, of the continued effectiveness of any
applicable hazard insurance policy, or a new policy meeting the requirements of
this Section is obtained. Any fee collected by the Servicer in respect of an
assumption or substitution of liability agreement will be retained by the
Servicer as additional servicing compensation. In connection with any such
assumption, no material term of the Mortgage Note (including but not limited to
the related Mortgage Rate and the amount of the Scheduled Payment) may be
amended or modified, except as otherwise required pursuant to the terms thereof.
The Servicer shall notify the Trustee that any such substitution, modification
or assumption agreement has been completed by forwarding to the Trustee or the
Custodian, as applicable, the executed original of such substitution or
assumption agreement, which document shall be added to the related Custodial
File and shall, for all purposes, be considered a part of such Custodial File to
the same extent as all other documents and instruments constituting a part
thereof.

            Notwithstanding the foregoing paragraph or any other provision of
this Agreement, the Servicer shall not be deemed to be in default, breach or any
other violation of its obligations hereunder by reason of any assumption of a
Mortgage Loan by operation of law or by the terms of the Mortgage Note or any
assumption which the Servicer may be restricted by law from preventing, for any
reason whatsoever. For purposes of this Section 3.14, the term "assumption" is
deemed to also include a sale (of the Mortgaged Property) subject to the
Mortgage that is not accompanied by an assumption or substitution of liability
agreement.

            Section 3.15 Realization upon Defaulted Mortgage Loans. The Servicer
shall use its best efforts, consistent with Accepted Servicing Practices, to
foreclose upon or otherwise comparably convert (which may include an acquisition
of REO Property) the ownership of properties securing such of the Mortgage Loans
as come into and continue in default and as to which no satisfactory
arrangements can be made for collection of delinquent payments pursuant to
Section 3.07, and which are not released from this Agreement pursuant to any
other provision hereof. The Servicer shall use reasonable efforts to realize
upon such defaulted Mortgage Loans in such manner as will maximize the receipt
of principal and interest by the Trustee, taking into account, among other
things, the timing of foreclosure proceedings; provided, however, with respect
to any Second Lien Mortgage Loan for which the related first lien mortgage loan
is not included in the Trust Fund, if, after such Mortgage Loan becomes 180 days
or more delinquent, the Servicer determines that a significant net recovery is
not possible through foreclosure, such Mortgage Loan may be charged off and the
Mortgage Loan will be treated as a Liquidated Mortgage Loan giving rise to a
Realized Loss. The foregoing is subject to the provisions that, in any case in
which Mortgaged Property shall have suffered damage from an uninsured cause, the
Servicer shall not be required to expend its own funds toward the restoration of
such property unless it shall determine in its sole discretion (i) that such
restoration will increase the net proceeds of liquidation of the related
Mortgage Loan to the Trustee, after reimbursement to itself for such expenses,
and (ii) that such expenses will be recoverable by the Servicer through
Insurance Proceeds, Condemnation Proceeds or Liquidation Proceeds from the
related Mortgaged Property, as contemplated in Section 3.11. The Servicer shall
be responsible for all other costs and expenses incurred by it in any such
proceedings; provided, however, that it shall be entitled to reimbursement
thereof from the related property, as contemplated in Section 3.11.

            The proceeds of any liquidation or REO Disposition, as well as any
recovery resulting from a partial collection of Insurance Proceeds, Condemnation
Proceeds or Liquidation Proceeds or any income from an REO Property, will be
applied in the following order of priority: first, to reimburse the Servicer or
any Subservicer for any related unreimbursed Servicing Advances, pursuant to
Section 3.11 or 3.17; second, to reimburse the Servicer for any related
unreimbursed P&I Advances, pursuant to Section 3.11; third, to accrued and
unpaid interest on the Mortgage Loan or REO Imputed Interest, at the Mortgage
Rate, to the date of the liquidation or REO Disposition, or to the Due Date
prior to the Remittance Date on which such amounts are to be distributed if not
in connection with a liquidation or REO Disposition; and fourth, as a recovery
of principal of the Mortgage Loan. If the amount of the recovery so allocated to
interest is less than a full recovery thereof, that amount will be allocated as
follows: first, to unpaid Servicing Fees; and second, as interest at the
Mortgage Rate (net of the Servicing Fee Rate). The portion of the recovery so
allocated to unpaid Servicing Fees shall be reimbursed to the Servicer or any
Subservicer pursuant to Section 3.11 or 3.17. The portions of the recovery so
allocated to interest at the Mortgage Rate (net of the Servicing Fee Rate) and
to principal of the Mortgage Loan shall be applied as follows: first, to
reimburse the Servicer or any Subservicer for any related unreimbursed Servicing
Advances in accordance with Section 3.11 or 3.17, and second, to the Trustee in
accordance with the provisions of Section 4.02, subject to the last paragraph of
Section 3.17 with respect to certain excess recoveries from an REO Disposition.

            Notwithstanding anything to the contrary contained herein, in
connection with a foreclosure or acceptance of a deed in lieu of foreclosure, in
the event the Servicer has received actual notice of, or has actual knowledge of
the presence of, hazardous or toxic substances or wastes on the related
Mortgaged Property, or if the Trustee otherwise requests, the Servicer shall
cause an environmental inspection or review of such Mortgaged Property to be
conducted by a qualified inspector. Upon completion of the inspection, the
Servicer shall promptly provide the Trustee and the Depositor with a written
report of the environmental inspection.

             After reviewing the environmental inspection report, the Depositor
shall determine how the Servicer shall proceed with respect to the Mortgaged
Property. In the event (a) the environmental inspection report indicates that
the Mortgaged Property is contaminated by hazardous or toxic substances or
wastes and (b) the Depositor directs the Servicer to proceed with foreclosure or
acceptance of a deed in lieu of foreclosure, the Servicer shall be reimbursed
for all reasonable costs associated with such foreclosure or acceptance of a
deed in lieu of foreclosure and any related environmental clean-up costs, as
applicable, from the related Liquidation Proceeds, or if the Liquidation
Proceeds are insufficient to fully reimburse the Servicer, the Servicer shall be
entitled to be reimbursed from amounts in the Collection Account pursuant to
Section 3.11. In the event the Depositor directs the Servicer not to proceed
with foreclosure or acceptance of a deed in lieu of foreclosure, the Servicer
shall be reimbursed from general collections for all Servicing Advances made
with respect to the related Mortgaged Property from the Collection Account
pursuant to Section 3.11.

            In the event the Servicer elects to charge-off a Second Lien
Mortgage Loan 180 days or more delinquent pursuant to this Section 3.15, no
Second Lien Mortgage Loan shall be characterized as a Liquidated Mortgage Loan
unless the Depositor consents in writing to such characterization after the
Servicer has provided the Depositor with a combined equity analysis of such
Second Lien Mortgage Loan and the related first lien mortgage loan; provided,
that if the Depositor has failed to notify the Servicer within 3 Business Days
of receipt of such combined equity analysis, then the Depositor shall be deemed
to have consented to such characterization.

            Section 3.16 Release of Mortgage Files. (a) Upon the payment in full
of any Mortgage Loan, or the receipt by the Servicer of a notification that
payment in full shall be escrowed in a manner customary for such purposes, the
Servicer will, on or before the last day of the month in which such payment in
full occurs, notify the Trustee or the Custodian, as applicable, by a
certification (which certification shall include a statement to the effect that
all amounts received or to be received in connection with such payment which are
required to be deposited in the Collection Account pursuant to Section 3.10 have
been or will be so deposited) of a Servicing Officer and shall request delivery
to it of the Custodial File by submitting a Request for Release to the Trustee
or the Custodian, as applicable. Upon receipt of such certification and Request
for Release (which may be in an electronic format acceptable to the Trustee or
the Custodian, as applicable), the Trustee or the Custodian, as applicable,
shall promptly release the related Custodial File to the Servicer within five
(5) Business Days. No expenses incurred in connection with any instrument of
satisfaction or deed of reconveyance shall be chargeable to the Collection
Account.

            (b) From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan, including, for this purpose, collection under
any Insurance Policy relating to the Mortgage Loans, the Trustee or the
Custodian, as applicable, shall, upon request of the Servicer and delivery to
the Trustee or the Custodian, as applicable, of a Request for Release, release
the related Custodial File to the Servicer, and the Trustee or the Custodian, as
applicable, shall, at the direction of the Servicer, execute such documents as
shall be necessary to the prosecution of any such proceedings and the Servicer
shall retain the Mortgage File in trust for the benefit of the Trustee. Such
Request for Release shall obligate the Servicer to return each and every
document previously requested from the Custodial File to the Trustee or the
Custodian, as applicable, when the need therefor by the Servicer no longer
exists, unless the Mortgage Loan has been charged-off or liquidated and the
Liquidation Proceeds relating to the Mortgage Loan have been deposited in the
Collection Account or 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 Property either judicially or non-judicially, and
the Servicer has delivered to the Trustee or the Custodian, as applicable, 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. Upon receipt of a certificate of a
Servicing Officer stating that such Mortgage Loan was charged-off or liquidated
and that all amounts received or to be received in connection with such
liquidation that are required to be deposited into the Collection Account have
been so deposited, or that such Mortgage Loan has become an REO Property, a copy
of the Request for Release shall be released by the Trustee or the Custodian, as
applicable, to the Servicer or its designee upon request therefor. Upon receipt
of a Request for Release under this Section 3.16, the Trustee or the Custodian,
as applicable, shall deliver the related Custodial File to the Servicer by
overnight courier (which delivery shall be at the Servicer's expense); provided,
however, that in the event the Servicer has not previously received copies of
the relevant Mortgage Loan Documents necessary to service the related Mortgage
Loan in accordance with Accepted Servicing Practices, the Responsible Party
shall reimburse the Servicer for any overnight courier charges incurred for the
requested Custodial Files.

            Upon written certification of a Servicing Officer, the Trustee shall
execute and deliver to the Servicer copies of any court pleadings, requests for
trustee's sale or other documents reasonably necessary to the foreclosure or
trustee's sale in respect of a Mortgaged Property or to any legal action brought
to obtain judgment against any Mortgagor on the Mortgage Note or Mortgage or to
obtain a deficiency judgment, or to enforce any other remedies or rights
provided by the Mortgage Note or Mortgage or otherwise available at law or in
equity, or shall exercise and deliver to the Servicer a power of attorney
sufficient to authorize the Servicer to execute such documents on its behalf.
Each such certification shall include a request that such pleadings or documents
be executed by the Trustee and a statement as to the reason such documents or
pleadings are required and that the execution and delivery thereof by the
Trustee will not invalidate or otherwise affect the lien of the Mortgage, except
for the termination of such a lien upon completion of the foreclosure or
trustee's sale.

            Section 3.17 Title, Conservation and Disposition of REO Property.
(a) This Section shall apply only to REO Properties acquired for the account of
the Trustee and shall not apply to any REO Property relating to a Mortgage Loan
which was purchased or repurchased from the Trustee pursuant to any provision
hereof. In the event that title to any such REO Property is acquired, the
Servicer shall cause the deed or certificate of sale to be issued in the name of
the Trustee, on behalf of the Certificateholders. Upon written request by the
Servicer, the Trustee shall provide the Servicer with a power of attorney
prepared by the Servicer with respect to such REO Property in the form of
Exhibit O and shall deliver such power of attorney by overnight courier at the
Servicer's expense.

            (b) The Servicer shall manage, conserve, protect and operate each
REO Property for the Trustee solely for the purpose of its prompt disposition
and sale. The Servicer, either itself or through an agent selected by the
Servicer, shall manage, conserve, protect and operate the REO Property in the
same manner that it manages, conserves, protects and operates other foreclosed
property for its own account, and in the same manner that similar property in
the same locality as the REO Property is managed. The Servicer shall attempt to
sell the same (and may temporarily rent the same for a period not greater than
one year, except as otherwise provided below) on such terms and conditions as
the Servicer deems to be in the best interest of the Trustee. The Trustee shall
have no obligations with respect to any REO Dispositions.

            (c) The Servicer shall segregate and hold all funds collected and
received in connection with the operation of any REO Property separate and apart
from its own funds and general assets and shall deposit such funds in the
Collection Account.

            (d) The Servicer shall deposit net of reimbursement to the Servicer
for any related outstanding Servicing Advances and unpaid Servicing Fees
provided in Section 3.11, or cause to be deposited, on a daily basis in the
Collection Account all revenues received with respect to the related REO
Property and shall withdraw therefrom funds necessary for the proper operation,
management and maintenance of the REO Property.

            (e) The Servicer, upon an REO Disposition, shall be entitled to
reimbursement for any related unreimbursed Servicing Advances as well as any
unpaid Servicing Fees from proceeds received in connection with the REO
Disposition, as further provided in Section 3.11.

            (f) Any net proceeds from an REO Disposition which are in excess of
the unpaid principal balance of the related Mortgage Loan plus all unpaid REO
Imputed Interest thereon through the date of the REO Disposition shall be
retained by the Servicer as additional servicing compensation.

            (g) The Servicer shall use its reasonable best efforts to sell, or
cause the Subservicer to sell, in accordance with Accepted Servicing Practices,
any REO Property as soon as possible, but in no event later than the conclusion
of the third calendar year beginning after the year of its acquisition by the
Lower Tier REMIC unless (i) the Servicer applies for an extension of such period
from the Internal Revenue Service pursuant to the REMIC Provisions and Code
Section 856(e)(3), in which event such REO Property shall be sold within the
applicable extension period, or (ii) the Servicer obtains for the Trustee an
Opinion of Counsel, addressed to the Depositor, the Trustee and the Servicer, to
the effect that the holding by the Lower Tier REMIC of such REO Property
subsequent to such period will not result in the imposition of taxes on
"prohibited transactions" as defined in Section 860F of the Code or cause the
Lower Tier REMIC or Upper Tier REMIC to fail to qualify as a REMIC under the
REMIC Provisions or comparable provisions of relevant state laws at any time.
The Servicer shall manage, conserve, protect and operate each REO Property for
the Trustee solely for the purpose of its prompt disposition and sale in a
manner which does not cause such REO Property to fail to qualify as "foreclosure
property" within the meaning of Section 860G(a)(8) or result in the receipt by
the Lower Tier REMIC of any "income from non-permitted assets" within the
meaning of Section 860F(a)(2)(B) of the Code or any "net income from foreclosure
property" which is subject to taxation under Section 860G(a)(1) of the Code.
Pursuant to its efforts to sell such REO Property, the Servicer shall either
itself or through an agent selected by the Servicer protect and conserve such
REO Property in the same manner and to such extent as is customary in the
locality where such REO Property is located and may, incident to its
conservation and protection of the interests of the Trustee on behalf of the
Certificateholders, rent the same, or any part thereof, as the Servicer deems to
be in the best interest of the Trustee on behalf of the Certificateholders for
the period prior to the sale of such REO Property; provided, however, that any
rent received or accrued with respect to such REO Property qualifies as "rents
from real property" as defined in Section 856(d) of the Code.

            Section 3.18 Notification of Adjustments. With respect to each
Adjustable Rate Mortgage Loan, the Servicer shall adjust the Mortgage Rate on
the related Adjustment Date and shall adjust the Scheduled Payment on the
related mortgage payment adjustment date, if applicable, in compliance with the
requirements of applicable law and the related Mortgage and Mortgage Note. In
the event that an Index becomes unavailable or otherwise unpublished, the
Servicer shall select a comparable alternative index over which it has no direct
control and which is readily verifiable. The Servicer shall execute and deliver
any and all necessary notices required under applicable law and the terms of the
related Mortgage Note and Mortgage regarding the Mortgage Rate and Scheduled
Payment adjustments. The Servicer shall promptly, upon written request therefor,
deliver to the Trustee such notifications and any additional applicable data
regarding such adjustments and the methods used to calculate and implement such
adjustments. Upon the discovery by the Servicer or the receipt of notice from
the Trustee that the Servicer has failed to adjust a Mortgage Rate or Scheduled
Pay
