                                   ARTICLE II

                          CONVEYANCE OF MORTGAGE LOANS;

                      ORIGINAL ISSUANCE OF THE CERTIFICATES

            SECTION 2.01      CONVEYANCE OF MORTGAGE LOANS.

            The Seller, concurrently with the execution and delivery hereof,
does hereby assign to the Trustee, without recourse all the right, title and
interest of the Seller in and to (a) the Trust Estate, including all interest
(other than the portion, if any, representing the Fixed Retained Yield) and
principal received by the Seller on or with respect to the Mortgage Loans after
the Cut-Off Date (and including scheduled payments of principal and interest due
after the Cut-Off Date but received by the Seller on or before the Cut-Off Date
and Unscheduled Principal Receipts received or applied on the Cut-Off Date, but
not including payments of principal and interest due on the Mortgage Loans on or
before the Cut-Off Date), (b) the Insurance Policies, (c) the obligations of the
Servicers under the Servicing Agreements with respect to the Mortgage Loans, (d)
all of the Seller's right, title and interest in and to each Mortgage 100SM
Pledge Agreement, each Parent Power(R) Guaranty and Security Agreement for
Securities Account and each Parent Power(R) Guaranty Agreement for Real Estate
with respect to each MLCC Additional Collateral Mortgage Loan, and (e) proceeds
of all the foregoing.

            In connection with such assignment, the Seller shall, with respect
to each Mortgage Loan, deliver, or cause to be delivered, to the Trust
Administrator, as initial Custodian, on or before the Closing Date, an Owner
Mortgage Loan File. If any Mortgage or an assignment of a Mortgage to the Trust
Administrator or any prior assignment is in the process of being recorded on the
Closing Date, the Seller shall deliver a copy thereof, certified by WFHM or the
applicable WFHM Correspondent to be a true and complete copy of the document
sent for recording, and the Seller shall use its best efforts to cause each such
original recorded document or certified copy thereof to be delivered to the
Trust Administrator promptly following its recordation, but in no event later
than one (1) year following the Closing Date. If any Mortgage has been recorded
in the name of Mortgage Electronic Registration System, Inc. ("MERS") or its
designee, no assignment of Mortgage in favor of the Trust Administrator will be
required to be prepared or delivered and instead, the Master Servicer shall take
all actions as are necessary to cause the Trust Estate 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. The Seller shall also cause to be delivered to the Trust Administrator any
other original mortgage loan document to be included in the Owner Mortgage Loan
File if a copy thereof has been delivered. The Seller shall pay from its own
funds, without any right of reimbursement therefor, the amount of any costs,
liabilities and expenses incurred by the Trust Estate by reason of the failure
of the Seller to cause to be delivered to the Trust Administrator within one (1)
year following the Closing Date any original Mortgage or assignment of a
Mortgage (except with respect to any Mortgage recorded in the name of MERS) not
delivered to the Trust Administrator on the Closing Date.

            In lieu of recording an assignment of any Mortgage the Seller may,
to the extent set forth in the applicable Servicing Agreement, deliver or cause
to be delivered to the Trust Administrator the assignment of the Mortgage Loan
from the Seller to the Trust Administrator in a form suitable for recordation,
in the states as to which the Trustee has received an Opinion of Counsel
acceptable to it that such recording is not required to make an assignment
effective against the parties to the Mortgage or subsequent purchasers or
encumbrancers of the Mortgaged Property. In the event that the Master Servicer
receives notice that recording is required to protect the right, title and
interest of the Trustee in and to any such Mortgage Loan for which recordation
of an assignment has not previously been required, the Master Servicer shall
promptly notify the Trust Administrator and the Trust Administrator shall within
five Business Days (or such other reasonable period of time mutually agreed upon
by the Master Servicer and the Trust Administrator) of its receipt of such
notice deliver each previously unrecorded assignment to the related Servicer for
recordation.

            SECTION 2.02      ACCEPTANCE BY TRUST ADMINISTRATOR.

            The Trust Administrator, on behalf of the Trustee acknowledges
receipt of the Mortgage Notes, the Mortgages, the assignments (unless the
related Mortgage has been registered in the name of MERS or its designee) and
other documents required to be delivered on the Closing Date pursuant to Section
2.01 above and declares that it holds and will hold such documents and the other
documents constituting a part of the Owner Mortgage Loan Files delivered to it
in trust, upon the trusts herein set forth, for the use and benefit of all
present and future Certificateholders. The Trust Administrator agrees, for the
benefit of Certificateholders, to review each Owner Mortgage Loan File within 45
days after execution of this Agreement in order to ascertain that all required
documents set forth in Section 2.01 have been executed and received and appear
regular on their face, and that such documents relate to the Mortgage Loans
identified in the Mortgage Loan Schedule, and in so doing the Trust
Administrator may rely on the purported due execution and genuineness of any
such document and on the purported genuineness of any signature thereon. If
within such 45 day period the Trust Administrator finds any document
constituting a part of an Owner Mortgage Loan File not to have been executed or
received or to be unrelated to the Mortgage Loans identified in the Mortgage
Loan Schedule or not to appear regular on its face, the Trust Administrator
shall promptly (and in no event more than 30 days after the discovery of such
defect) notify the Seller, which shall have a period of 60 days after the date
of such notice within which to correct or cure any such defect. The Seller
hereby covenants and agrees that, if any material defect is not so corrected or
cured, the Seller will, not later than 60 days after the Trust Administrator's
notice to it referred to above respecting such defect, either (i) repurchase the
related Mortgage Loan or any property acquired in respect thereof from the Trust
Estate at a price equal to (a) 100% of the unpaid principal balance of such
Mortgage Loan plus (b) accrued interest at the Mortgage Interest Rate less any
Fixed Retained Yield through the last day of the month in which such repurchase
takes place or (ii) if within two years of the Startup Day, or such other period
permitted by the REMIC Provisions, substitute for any Mortgage Loan to which
such material defect relates, a new mortgage loan (a "Substitute Mortgage Loan")
having such characteristics so that the representations and warranties of the
Seller set forth in Section 2.03(b) hereof (other than Section 2.03(b)(i)) would
not have been incorrect had such Substitute Mortgage Loan originally been a
Mortgage Loan. In no event shall any Substitute Mortgage Loan have an unpaid
principal balance, as of the date of substitution, greater than the Scheduled
Principal Balance (reduced by the scheduled payment of principal due on the Due
Date in the month of substitution) of the Mortgage Loan for which it is
substituted. In addition, such Substitute Mortgage Loan shall have a
Loan-to-Value Ratio less than or equal to and a Mortgage Interest Rate equal to
that of the Mortgage Loan for which it is substituted.

            In the case of a repurchased Mortgage Loan or property, the purchase
price shall be deposited by the Seller in the Certificate Account maintained by
the Master Servicer pursuant to Section 3.01. In the case of a Substitute
Mortgage Loan, the Owner Mortgage Loan File relating thereto shall be delivered
to the Trust Administrator and the Substitution Principal Amount, together with
(i) interest on such Substitution Principal Amount at the applicable Net
Mortgage Interest Rate to the following Due Date of such Mortgage Loan which is
being substituted for and (ii) an amount equal to the aggregate amount of
unreimbursed Periodic Advances in respect of interest previously made by the
Servicer, the Master Servicer or the Trust Administrator with respect to such
Mortgage Loan, shall be deposited in the Certificate Account. The Monthly
Payment on the Substitute Mortgage Loan for the Due Date in the month of
substitution shall not be part of the Trust Estate. Upon receipt by the Trust
Administrator of written notification of any such deposit signed by an officer
of the Seller, or the new Owner Mortgage Loan File, as the case may be, the
Trust Administrator shall release to the Seller the related Owner Mortgage Loan
File and shall execute and deliver such instrument of transfer or assignment
(or, in the case of a Mortgage Loan registered in the name of MERS or its
designee, the Master Servicer shall take all necessary action to reflect such
assignment on the records of MERS), in each case without recourse, as shall be
necessary to vest in the Seller legal and beneficial ownership of such
substituted or repurchased Mortgage Loan or property. It is understood and
agreed that the obligation of the Seller to substitute a new Mortgage Loan for
or repurchase any Mortgage Loan or property as to which such a material defect
in a constituent document exists shall constitute the sole remedy respecting
such defect available to the Certificateholders, the Trust Administrator on
behalf of the Trustee and the Trustee on behalf of the Certificateholders. The
failure of the Trust Administrator to give any notice contemplated herein within
forty-five (45) days after the execution of this Agreement shall not affect or
relieve the Seller's obligation to repurchase any Mortgage Loan pursuant to this
Section 2.02.

            The Trust Administrator may, concurrently with the execution and
delivery hereof or at any time thereafter, enter into a Custodial Agreement
substantially in the form of Exhibit E hereto pursuant to which the Trust
Administrator appoints a Custodian to hold the Mortgage Notes, the Mortgages,
the assignments and other documents related to the Mortgage Loans received by
the Trust Administrator, as agent for the Trustee in trust for the benefit of
all present and future Certificateholders, which may provide, among other
things, that the Custodian shall conduct the review of such documents required
under the first paragraph of this Section 2.02.

            SECTION 2.03 REPRESENTATIONS AND WARRANTIES OF THE
                         MASTER SERVICER AND THE SELLER.

            (a) The Master Servicer hereby represents and warrants to the
Trustee and the Trust Administrator for the benefit of Certificateholders that,

               (ii) The execution and delivery of this Agreement by the Master
      Servicer and its performance and compliance with the terms of this
      Agreement will not violate the Master Servicer's corporate charter or
      by-laws or constitute a default (or an event which, with notice or lapse
      of time, or both, would constitute a default) under, or result in the
      breach of, any material contract, agreement or other instrument to which
      the Master Servicer is a party or which may be applicable to the Master
      Servicer or any of its assets;

               (iii) This Agreement, assuming due authorization, execution and
      delivery by the Trustee, the Trust Administrator and the Seller,
      constitutes a valid, legal and binding obligation of the Master Servicer,
      enforceable against it in accordance with the terms hereof subject to
      applicable bankruptcy, insolvency, reorganization, moratorium and other
      laws affecting the enforcement of creditors' rights generally and to
      general principles of equity, regardless of whether such enforcement is
      considered in a proceeding in equity or at law;

               (iv) The Master Servicer 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, which default might have
      consequences that would materially and adversely affect the condition
      (financial or other) or operations of the Master Servicer or its
      properties or might have consequences that would affect its performance
      hereunder; and

            (v) No litigation is pending or, to the best of the Master
Servicer's knowledge, threatened against the Master Servicer which would
prohibit its entering into this Agreement or performing its obligations under

      Association mortgagee title insurance policy or other generally acceptable
      form of policy or insurance acceptable to FNMA or FHLMC, issued by a title
      insurer acceptable to FNMA or FHLMC insuring the originator, its
      successors and assigns, as to the first priority lien of the Mortgage in

      the lien of current real property taxes and assessments not yet due and
      payable, (B) covenants, conditions and restrictions, rights of way,
      easements and other matters of public record as of the date of recording

      are commonly subject which do not individually, or in the aggregate,
      materially interfere with the benefits of the security intended to be
      provided by the Mortgage; the Seller is the sole insured of such mortgagee
      title insurance policy, the assignment to the Trust Administrator, on
      behalf of the Trustee of the Seller's interest in such mortgagee title
      insurance policy does not require any consent of or notification to the
      insurer which has not been obtained or made, such mortgagee title
      insurance policy is in full force and effect and will be in full force and
      effect and inure to the benefit of the Trust Administrator, on behalf of
      the Trustee, no claims have been made under such mortgagee title insurance
      policy, and no prior holder of the related Mortgage, including the Seller,

      such mortgagee title insurance policy;

               (xvi) The Mortgaged Property securing each Mortgage Loan is
      insured by an insurer acceptable to FNMA or FHLMC against loss by fire and
      such hazards as are covered under a standard extended coverage
      endorsement, in an amount which is not less than the lesser of 100% of the
      insurable value of the Mortgaged Property and the outstanding principal
      balance of the Mortgage Loan, but in no event less than the minimum amount
      necessary to fully compensate for any damage or loss on a replacement cost
      basis; if the Mortgaged Property is a condominium unit, it is included
      under the coverage afforded by a blanket policy for the project; if upon
      origination of the Mortgage Loan, the improvements on the Mortgaged
      Property were in an area identified in the Federal Register by the Federal
      Emergency Management Agency as having special flood hazards, a flood
      insurance policy meeting the requirements of the current guidelines of the
      Federal Insurance Administration is in effect with a generally acceptable
      insurance carrier, in an amount representing coverage not less than the
      least of (A) the outstanding principal balance of the Mortgage Loan, (B)
      the full insurable value of the Mortgaged Property and (C) the maximum
      amount of insurance which was available under the National Flood Insurance
      Act of 1968, as amended; and each Mortgage obligates the Mortgagor
      thereunder to maintain all such insurance at the Mortgagor's cost and
      expense;

               (xvii) To the best of the Seller's knowledge, there is no
      default, breach, violation or event of acceleration existing under the
      Mortgage or the related Mortgage Note and no event which, with the passage
      of time or with notice and the expiration of any grace or cure period,
      would constitute a default, breach, violation or event of acceleration;
      the Seller has not waived any default, breach, violation or event of
      acceleration; and no foreclosure action is currently threatened or has
      been commenced with respect to the Mortgage Loan;

               (xviii) No Mortgage Note or Mortgage is subject to any right of
      rescission, set-off, counterclaim or defense, including the defense of
      usury, nor will the operation of any of the terms of the Mortgage Note or
      Mortgage, or the exercise of any right thereunder, render the Mortgage
      Note or Mortgage unenforceable, in whole or in part, or subject it to any
      right of rescission, set-off, counterclaim or defense, including the
      defense of usury, and no such right of rescission, set-off, counterclaim
      or defense has been asserted with respect thereto;

               (xix) Each Mortgage Note is payable in monthly payments,
      resulting in complete amortization of the Mortgage Loan over a term of not
      more than 360 months;

               (xx) Each Mortgage contains customary and enforceable provisions
      such as to render the rights and remedies of the holder thereof adequate
      for the realization against the Mortgaged Property of the benefits of the
      security, including realization by judicial foreclosure (subject to any
      limitation arising from any bankruptcy, insolvency or other law for the
      relief of debtors), and there is no homestead or other exemption available
      to the Mortgagor which would interfere with such right of foreclosure;

               (xxi)    To  the  best  of  the  Seller's  knowledge,  no
      Mortgagor  is a debtor  in any  state  or  federal  bankruptcy  or
      insolvency proceeding;

               (xxii) Each Mortgaged Property is located in the United States
      and consists of a one- to four-unit residential property, which may
      include a detached home, townhouse, condominium unit or a unit in a
      planned unit development or, in the case of Mortgage Loans secured by
      Co-op Shares, leases or occupancy agreements;

               (xxiii)  The  Mortgage  Loan  is a  "qualified  mortgage"
      within the meaning of Section 860G(a)(3) of the Code;

               (xxiv) With respect to each Mortgage where a lost note affidavit
      has been delivered to the Trust Administrator in place of the related
      Mortgage Note, the related Mortgage Note is no longer in existence;

               (xxv) In the event that the Mortgagor is an inter vivos "living"
      trust, (i) such trust is in compliance with FNMA or FHLMC standards for
      inter vivos trusts and (ii) holding title to the Mortgaged Property in
      such trust will not diminish any rights as a creditor including the right
      to full title to the Mortgaged Property in the event foreclosure
      proceedings are initiated; and

               (xxvi) If the Mortgage Loan is secured by a long-term residential
      lease, (1) the lessor under the lease holds a fee simple interest in the
      land; (2) the terms of such lease expressly permit the mortgaging of the
      leasehold estate, the assignment of the lease without the lessor's consent
      and the acquisition by the holder of the Mortgage of the rights of the
      lessee upon foreclosure or assignment in lieu of foreclosure or provide
      the holder of the Mortgage with substantially similar protections; (3) the
      terms of such lease do not (a) allow the termination thereof upon the
      lessee's default without the holder of the Mortgage being entitled to
      receive written notice of, and opportunity to cure, such default, (b)
      allow the termination of the lease in the event of damage or destruction
      as long as the Mortgage is in existence, (c) prohibit the holder of the
      Mortgage from being insured (or receiving proceeds of insurance) under the
      hazard insurance policy or policies relating to the Mortgaged Property or
      (d) permit any increase in rent other than pre-established increases set
      forth in the lease; (4) the original term of such lease is not less than
      15 years; (5) the term of such lease does not terminate earlier than five
      years after the maturity date of the Mortgage Note; and (6) the Mortgaged
      Property is located in a jurisdiction in which the use of leasehold
      estates in transferring ownership in residential properties is a widely
      accepted practice;

            Notwithstanding the foregoing, no representations or warranties are
made by the Seller as to the environmental condition of any Mortgaged Property;
the absence, presence or effect of hazardous wastes or hazardous substances on
any Mortgaged Property; any casualty resulting from the presence or effect of
hazardous wastes or hazardous substances on, near or emanating from any
Mortgaged Property; the impact on Certificateholders of any environmental
condition or presence of any hazardous substance on or near any Mortgaged
Property; or the compliance of any Mortgaged Property with any environmental
laws, nor is any agent, person or entity otherwise affiliated with the Seller
authorized or able to make any such representation, warranty or assumption of
liability relative to any Mortgaged Property. In addition, no representations or
warranties are made by the Seller with respect to the absence or effect of fraud
in the origination of any Mortgage Loan.

            It is understood and agreed that the representations and warranties
set forth in this Section 2.03(b) shall survive delivery of the respective Owner
Mortgage Loan Files to the Trust Administrator and shall inure to the benefit of
the Trust Administrator, on behalf of the Trustee, notwithstanding any
restrictive or qualified endorsement or assignment.

            (c) Upon discovery by either the Seller, the Master Servicer, the
Trustee, the Trust Administrator or the Custodian that any of the
representations and warranties made in subsection (b) above is not accurate
(referred to herein as a "breach") and, except for a breach of the
representation and warranty set forth in subsection (b)(i), where such breach is
a result of the Cut-Off Date Principal Balance of a Mortgage Loan being greater,
by $5,000 or greater, than the Cut-Off Date Principal Balance of such Mortgage
Loan indicated on the Mortgage Loan Schedule, that such breach materially and
adversely affects the interests of the Certificateholders in the related
Mortgage Loan, the party discovering such breach shall give prompt written
notice to the other parties (any Custodian being so obligated under a Custodial
Agreement). Within 60 days of the earlier of its discovery or its receipt of
notice of any such breach, the Seller shall cure such breach in all material
respects or shall either (i) repurchase the Mortgage Loan or any property
acquired in respect thereof from the Trust Estate at a price equal to (A) 100%
of the unpaid principal balance of such Mortgage Loan plus (B) accrued interest
at the Net Mortgage Interest Rate for such Mortgage Loan through the last day of
the month in which such repurchase took place or (ii) if within two years of the
Startup Day, or such other period permitted by the REMIC Provisions, substitute
for such Mortgage Loan in the manner described in Section 2.02. The purchase
price of any repurchase described in this paragraph and the Substitution
Principal Amount, if any, plus accrued interest thereon and the other amounts
referred to in Section 2.02, shall be deposited in the Certificate Account. It
is understood and agreed that the obligation of the Seller to repurchase or
substitute for any Mortgage Loan or property as to which such a breach has
occurred and is continuing shall constitute the sole remedy respecting such
breach available to Certificateholders, the Trust Administrator on behalf of the
Trustee, or the Trustee on behalf of Certificateholders, and such obligation
shall survive until termination of the Trust Estate hereunder.

            SECTION 2.04 EXECUTION AND DELIVERY OF CERTIFICATES.

            The Trust Administrator acknowledges the assignment to it of the
Mortgage Loans and the delivery of the Owner Mortgage Loan Files to it, and,
concurrently with such delivery, (i) acknowledges the issuance of and hereby
declares that it holds the Uncertificated Lower-Tier Interests on behalf of the
Upper-Tier REMIC and Certificateholders and (ii) has executed and delivered to

Certificates in authorized denominations which, together with the Uncertificated
Lower-Tier Interests, evidence ownership of the entire Trust Estate.

                         OF STARTUP DAY AND LATEST POSSIBLE MATURITY

                                   ARTICLE III

                       ADMINISTRATION OF THE TRUST ESTATE:
                         SERVICING OF THE MORTGAGE LOANS

                        SECTION 3.01 CERTIFICATE ACCOUNT.

            (a) The Master Servicer shall establish and maintain a Certificate
Account for the deposit of funds received by the Master Servicer with respect to
the Mortgage Loans serviced by each Servicer pursuant to each of the Servicing
Agreements. Such account shall be maintained as an Eligible Account. The Master
Servicer shall give notice to each Servicer and the Seller of the location of
the Certificate Account and of any change in the location thereof.

            (b) The Master Servicer shall deposit into the Certificate Account
on the day of receipt thereof all amounts received by it from any Servicer
pursuant to any of the Servicing Agreements, any amounts received by it upon the
sale of any MLCC Additional Collateral pursuant to the terms of the Mortgage
100SM Pledge Agreement, the Parent Power(R) Guaranty and Security Agreement for
Securities Account or the Parent Power(R) Guaranty Agreement for Real Estate or
any amounts received pursuant to the MLCC Surety Bond, and shall, in addition,
deposit into the Certificate Account the following amounts, in the case of
amounts specified in clause (i), not later than the Distribution Date on which
such amounts are required to be distributed to Certificateholders and, in the
case of the amounts specified in clause (ii), not later than the Business Day
next following the day of receipt and posting by the Master Servicer:

               (i)Periodic Advances pursuant to Section 3.03(a) made by the
      Master Servicer or the Trust Administrator, if any and any amounts deemed
      received by the Master Servicer pursuant to Section 3.01(d); and

               (ii) in the case of any Mortgage Loan that is repurchased by the
      Seller pursuant to Sections 2.02 or 2.03 or that is auctioned by the
      Master Servicer pursuant to Section 3.08 or purchased by the Master
      Servicer pursuant to Section 3.08 or 9.01, the purchase price therefor or,
      where applicable, any Substitution Principal Amount and any amounts
      received in respect of the interest portion of unreimbursed Periodic
      Advances.

            (c) The Master Servicer shall cause the funds in the Certificate
Account to be invested in Eligible Investments. No such Eligible Investments
will be sold or disposed of at a gain prior to maturity unless the Master
Servicer has received an Opinion of Counsel or other evidence satisfactory to it
that such sale or disposition will not cause the Trust Estate to be subject to
Prohibited Transactions Tax, otherwise subject the Trust Estate to tax, or cause
either of the Upper-Tier REMIC or the Lower-Tier REMIC to fail to qualify as a
REMIC while any Certificates are outstanding. Any amounts deposited in the
Certificate Account prior to the Distribution Date shall be invested for the
account of the Master Servicer and any investment income thereon shall be
additional compensation to the Master Servicer for services rendered under this
Agreement. The amount of any losses incurred in respect of any such investments
shall be deposited in the Certificate Account by the Master Servicer out of its
own funds immediately as realized.

            (d) For purposes of this Agreement, the Master Servicer will be
deemed to have received from a Servicer on the applicable Remittance Date for
such funds all amounts deposited by such Servicer into the Custodial Account for
P&I maintained in accordance with the applicable Servicing Agreement, if such
Custodial Account for P&I is not an Eligible Account as defined in this
Agreement, to the extent such amounts are not actually received by the Master
Servicer on such Remittance Date as a result of the bankruptcy, insolvency,
receivership or other financial distress of the depository institution in which
such Custodial Account for P&I is being held. To the extent that amounts so
deemed to have been received by the Master Servicer are subsequently remitted to
the Master Servicer, the Master Servicer shall be entitled to retain such
amounts.

                   SECTION 3.02 PERMITTED WITHDRAWALS FROM THE
                                CERTIFICATE ACCOUNT.

            (a) The Master Servicer may, from time to time, make withdrawals
from the Certificate Account for the following purposes (limited, in the case of
Servicer reimbursements, to cases where funds in the respective Custodial P&I
Account are not sufficient therefor):

               (i)to reimburse the Master Servicer, the Trust Administrator or
      any Servicer for Periodic Advances made by the Master Servicer or the
      Trust Administrator pursuant to Section 3.03(a) or any Servicer pursuant
      to any Servicing Agreement with respect to previous Distribution Dates,
      such right to reimbursement pursuant to this subclause (i) being limited
      to amounts received on or in respect of particular Mortgage Loans
      (including, for this purpose, Liquidation Proceeds, REO Proceeds and
      proceeds from the purchase, sale, repurchase or substitution of Mortgage
      Loans pursuant to Sections 2.02, 2.03, 2.06, 3.08 or 9.01) respecting
      which any such Periodic Advance was made;

               (ii) to reimburse any Servicer, the Master Servicer or the Trust
      Administrator for any Periodic Advances determined in good faith to have
      become Nonrecoverable Advances provided, however, that any portion of
      Nonrecoverable Advances representing Fixed Retained Yield shall be
      reimbursable only from amounts constituting Fixed Retained Yield and not
      from the assets of the Trust Estate;

               (iii) to reimburse the Master Servicer or any Servicer from
      Liquidation Proceeds for Liquidation Expenses and for amounts expended by
      the Master Servicer or any Servicer pursuant hereto or to any Servicing
      Agreement, respectively, in good faith in connection with the restoration
      of damaged property or for foreclosure expenses;

               (iv) from any Mortgagor payment on account of interest or other
      recovery (including Net REO Proceeds) with respect to a particular
      Mortgage Loan, to pay the Master Servicing Fee with respect to such
      Mortgage Loan to the Master Servicer;

               (v)to reimburse the Master Servicer, any Servicer or the Trust
      Administrator (or, in certain cases, the Seller) for expenses incurred by
      it (including taxes paid on behalf of the Trust Estate) and recoverable by
      or reimbursable to it pursuant to Section 3.03(c), 3.03(d) or 6.03 or the
      second sentence of Section 8.14(a) or pursuant to such Servicer's
      Servicing Agreement, provided such expenses are "unanticipated" within the
      meaning of the REMIC Provisions;

               (vi) to pay to the Seller or other purchaser with respect to each
      Mortgage Loan or property acquired in respect thereof that has been
      repurchased or replaced pursuant to Sections 2.02, 2.03 or 2.06 or
      auctioned pursuant to Section 3.08 or to pay to the Master Servicer with
      respect to each Mortgage Loan or property acquired in respect thereof that
      has been purchased pursuant to Section 3.08 or 9.01, all amounts received
      thereon and not required to be distributed as of the date on which the
      related repurchase or purchase price or Scheduled Principal Balance was
      determined;

               (vii)    to  remit  funds  to  the  Paying  Agent  in the
      amounts and in the manner provided for herein;

               (viii)   to pay  to  the  Master  Servicer  any  interest
      earned  on or  investment  income  with  respect  to  funds in the
      Certificate Account;

               (ix) to pay to the Master Servicer or any Servicer out of
      Liquidation Proceeds allocable to interest the amount of any unpaid Master
      Servicing Fee or Servicing Fee (as adjusted pursuant to the related
      Servicing Agreement) and any unpaid assumption fees, late payment charges
      or other Mortgagor charges on the related Mortgage Loan;

               (x)to pay to the Master Servicer as additional master servicing
      compensation any Liquidation Profits which a Servicer is not entitled to
      pursuant to the applicable Servicing Agreement;

               (xi)     to  withdraw  from the  Certificate  Account any
      amount deposited in the Certificate  Account that was not required
      to be deposited therein;

               (xii)    to clear and terminate the  Certificate  Account
      pursuant to Section 9.01; and

               (xiii) to pay to WFHM from any Mortgagor payment on account of
      interest or other recovery (including Net REO Proceeds) with respect to a
      particular Mortgage Loan, the Fixed Retained Yield, if any, with respect
      to such Mortgage Loan; provided, however, that with respect to any payment
      of interest received by the Master Servicer in respect of a Mortgage Loan
      (whether paid by the Mortgagor or received as Liquidation Proceeds,
      Insurance Proceeds or otherwise) which is less than the full amount of
      interest then due with respect to such Mortgage Loan, only that portion of
      such payment of interest that bears the same relationship to the total
      amount of such payment of interest as the Fixed Retained Yield Rate, if
      any, in respect of such Mortgage Loan bears to the Mortgage Interest Rate
      shall be allocated to the Fixed Retained Yield with respect thereto.

            (b) The Master Servicer shall keep and maintain separate accounting,
on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
payment to and withdrawal from the Certificate Account.

            SECTION 3.03 ADVANCES BY MASTER SERVICER AND TRUST
                         ADMINISTRATOR.

            (a) In the event an Other Servicer fails to make any required
Periodic Advances of principal and interest on a Mortgage Loan as required by
the related Other Servicing Agreement prior to the Distribution Date occurring
in the month during which such Periodic Advance is due, the Master Servicer
shall make Periodic Advances to the extent provided hereby. In addition, if
under the terms of an Other Servicing Agreement, the applicable Servicer is not
required to make Periodic Advances on a Mortgage Loan or REO Mortgage Loan
through the liquidation of such Mortgage Loan or REO Mortgage Loan, the Master
Servicer to the extent provided hereby shall make the Periodic Advances thereon
during the period the Servicer is not obligated to do so. In the event WFHM
fails to make any required Periodic Advances of principal and interest on a
Mortgage Loan as required by the WFHM Servicing Agreement prior to the
Distribution Date occurring in the month during which such Periodic Advance is
due, the Trust Administrator shall, to the extent required by Section 8.15, make
such Periodic Advance to the extent provided hereby, provided that the Trust
Administrator has previously received the certificate of the Master Servicer
described in the following sentence. The Master Servicer shall certify to the
Trust Administrator with respect to any such Distribution Date (i) the amount of
Periodic Advances required of WFHM or such Other Servicer, as the case may be,
(ii) the amount actually advanced by WFHM or such Other Servicer, (iii) the
amount that the Trust Administrator or Master Servicer is required to advance
hereunder including any amount the Master Servicer is required to advance
pursuant to the second sentence of this Section 3.03(a) and (iv) whether the
Master Servicer has determined that it reasonably believes that such Periodic
Advance is a Nonrecoverable Advance. Amounts advanced by the Trust Administrator
or Master Servicer shall be deposited in the Certificate Account on the related
Distribution Date. Notwithstanding the foregoing, neither the Master Servicer
nor the Trust Administrator will be obligated to make a Periodic Advance that it
reasonably believes to be a Nonrecoverable Advance. The Trust Administrator may
conclusively rely for any determination to be made by it hereunder upon the
determination of the Master Servicer as set forth in its certificate.

            (b) To the extent an Other Servicer fails to make an advance on
account of the taxes or insurance premiums with respect to a Mortgage Loan
required pursuant to the related Other Servicing Agreement, the Master Servicer
shall, if the Master Servicer knows of such failure of the Servicer, advance
such funds and take such steps as are necessary to pay such taxes or insurance
premiums. To the extent WFHM fails to make an advance on account of the taxes or
insurance premiums with respect to a Mortgage Loan required pursuant to the WFHM
Servicing Agreement, the Master Servicer shall, if the Master Servicer knows of
such failure of WFHM, certify to the Trust Administrator that such failure has
occurred. Upon receipt of such certification, the Trust Administrator shall
advance such funds and take such steps as are necessary to pay such taxes or
insurance premiums.

            (c) The Master Servicer and the Trust Administrator shall each be
entitled to be reimbursed from the Certificate Account for any Periodic Advance
made by it under Section 3.03(a) to the extent described in Section 3.02(a)(i)
and (a)(ii). The Master Servicer and the Trust Administrator shall be entitled
to be reimbursed pursuant to Section 3.02(a)(v) for any advance by it pursuant
to Section 3.03(b). The Master Servicer shall diligently pursue restoration of
such amount to the Certificate Account from the related Servicer. The Master
Servicer shall, to the extent it has not already done so, upon the request of
the Trust Administrator, withdraw from the Certificate Account and remit to the
Trust Administrator any amounts to which the Trust Administrator is entitled as
reimbursement pursuant to Section 3.02 (a)(i), (ii) and (v).

            (d) Except as provided in Section 3.03(a) and (b), neither the
Master Servicer nor the Trust Administrator shall be required to pay or advance
any amount which any Servicer was required, but failed, to deposit in the
Certificate Account.

            SECTION 3.04 TRUST ADMINISTRATOR TO COOPERATE;
                         RELEASE OF OWNER MORTGAGE LOAN FILES.

            Upon the receipt by the Master Servicer of a Request for Release in
connection with the deposit by a Servicer into the Certificate Account of the
proceeds from a Liquidated Loan or of a Prepayment in Full, the Master Servicer
shall confirm to the Trust Administrator that all amounts required to be
remitted to the Certificate Account in connection with such Mortgage Loan have
been so deposited, and shall deliver such Request for Release to the Trust
Administrator. The Trust Administrator shall, within five Business Days of its
receipt of such a Request for Release, release the related Owner Mortgage Loan
File to the Master Servicer or such Servicer, as requested by the Master
Servicer. No expenses incurred in connection with any instrument of satisfaction
or deed of reconveyance shall be chargeable to the Certificate Account.

            From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan, including but not limited to, collection under
any insurance policies, or to effect a partial release of any Mortgaged Property
from the lien of the Mortgage, the Servicer of such Mortgage Loan shall deliver
to the Master Servicer a Request for Release. Upon the Master Servicer's receipt
of any such Request for Release, the Master Servicer shall promptly forward such
request to the Trust Administrator and the Trust Administrator shall, within
five Business Days, release the related Owner Mortgage Loan File to the Master
Servicer or such Servicer, as requested by the Master Servicer. Any such Request
for Release shall obligate the Master Servicer or such Servicer, as the case may
be, to return each and every document previously requested from the Owner
Mortgage Loan File to the Trust Administrator by the twenty-first day following
the release thereof, unless (i) the Mortgage Loan has been liquidated and the
Liquidation Proceeds relating to the Mortgage Loan have been deposited in the
Certificate Account or (ii) the Owner Mortgage Loan 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 Master Servicer has delivered to the Trust Administrator
a certificate of the Master Servicer or such Servicer certifying as to the name
and address of the Person to which such Owner Mortgage Loan File or such
document was delivered and the purpose or purposes of such delivery. Upon
receipt of an Officer's Certificate of the Master Servicer or such Servicer
stating that such Mortgage Loan was liquidated and that all amounts received or
to be received in connection with such liquidation which are required to be
deposited into the Certificate Account have been so deposited, or that such
Mortgage Loan has become an REO Mortgage Loan, the Request for Release shall be
released by the Trust Administrator to the Master Servicer or such Servicer, as
appropriate.

            Upon written certification of the Master Servicer or the Servicer of
such Mortgage Loan, the Trust Administrator shall execute and deliver to the
Master Servicer or such Servicer, as directed by the Master Servicer, court
pleadings, requests for trustee's sale or other documents 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. Each such certification shall include a request that such
pleadings or documents be executed by the Trust Administrator and a statement as
to the reason such documents or pleadings are required and that the execution
and delivery thereof by the Trust Administrator will not invalidate or otherwise
affect the lien of the Mortgage, except for the termination of such a lien upon
completion of the foreclosure proceeding or trustee's sale.

            SECTION 3.05 REPORTS TO THE TRUSTEE AND THE TRUST
                         ADMINISTRATOR; ANNUAL COMPLIANCE STATEMENTS.

            (a) Not later than 15 days after each Distribution Date, the Master
Servicer shall deliver to the Trustee and the Trust Administrator a statement
setting forth the status of the Certificate Account as of the close of business
on such Distribution Date stating that all distributions required to be made by
the Master Servicer under this Agreement have been made (or, if any required
distribution has not been made by the Master Servicer, specifying the nature and
status thereof) and showing, for the period covered by such statement, the
aggregate amount of deposits into and withdrawals from such account for each
category of deposit and withdrawal specified in Sections 3.01 and 3.02. Such
statement may be in the form of the then current FNMA monthly accounting report
for its Guaranteed Mortgage Pass-Through Program with appropriate additions and
changes, and shall also include information as to the aggregate unpaid principal
balance of all of the Mortgage Loans as of the close of business as of the last
day of the calendar month immediately preceding such Distribution Date. Copies
of such statement shall be provided by the Trust Administrator to any
Certificateholder upon written request, provided such statement is delivered, or
caused to be delivered, by the Master Servicer to the Trust Administrator.

            (b) The Master Servicer shall deliver to the Trustee and the Trust
Administrator on or before April 30 of each year, a certificate signed by an
officer of the Master Servicer, certifying that (i) such officer has reviewed
the activities of the Master Servicer during the preceding calendar year or
portion thereof and its performance under this agreement and (ii) to the best of
such officer's knowledge, based on such review, the Master Servicer has
performed and fulfilled its duties, responsibilities and obligations under this
agreement in all material respects throughout such year, or, if there has been a
default in the fulfillment of any such duties, responsibilities or obligations,
specifying each such default known to such officer and the nature and status
thereof, and, (iii) (A) the Master Servicer has received from each Servicer any
financial statements, officer's certificates, accountant's statements or other
information required to be provided to the Master Servicer pursuant to the
related Servicing Agreement and (B) to the best of such officer's knowledge,
based on a review of the information provided to the Master Servicer by each
Servicer as described in (iii)(A) above, each Servicer has performed and
fulfilled its duties, responsibilities and obligations under the related
Servicing Agreement in all material respects throughout such year, or, if there
has been a default in the fulfillment of any such duties, responsibilities or
obligations, specifying each such default known to such officer and the nature
and status thereof. Copies of such officers' certificate shall be provided by
the Trust Administrator to any Certificateholder upon written request provided
such certificate is delivered, or caused to be delivered, by the Master Servicer
to the Trust Administrator.

            SECTION 3.06 TITLE, MANAGEMENT AND DISPOSITION OF ANY
                         REO MORTGAGE LOAN.

            The Master Servicer shall ensure that each REO Mortgage Loan is
administered by the related Servicer at all times so that it qualifies as
"foreclosure property" under the REMIC Provisions and that it does not earn any
"net income from foreclosure property" which is subject to tax under the REMIC
Provisions. In the event that a Servicer is unable to dispose of any REO
Mortgage Loan within the period mandated by each of the Servicing Agreements,
the Master Servicer shall monitor such Servicer to verify that such REO Mortgage
Loan is auctioned to the highest bidder within the period so specified. In the
event of any such sale of REO Mortgage Loan, the Trust Administrator shall, at
the written request of the Master Servicer and upon being supported with
appropriate forms therefor, within five Business Days of the deposit by the
Master Servicer of the proceeds of such sale or auction into the Certificate
Account, release or cause to be released to the entity identified by the Master
Servicer the related Owner Mortgage Loan File and Servicer Mortgage Loan File
and shall execute and deliver such instruments of transfer or assignment, in
each case without recourse, as shall be necessary to vest in the auction
purchaser title to the REO Mortgage Loan and the Trust Administrator shall have
no further responsibility with regard to such Owner Mortgage Loan File or
Servicer Mortgage Loan File. Neither the Trust Administrator, the Master
Servicer nor any Servicer, acting on behalf of the Trust Estate, shall provide
financing from the Trust Estate to any purchaser of an REO Mortgage Loan.

            SECTION 3.07 AMENDMENTS TO SERVICING AGREEMENTS,
                         MODIFICATION OF STANDARD PROVISIONS.

            (a) Subject to the prior written consent of the Trustee and the
Trust Administrator pursuant to Section 3.07(b), the Master Servicer from time
to time may, to the extent permitted by the applicable Servicing Agreement, make
such modifications and amendments to such Servicing Agreement as the Master
Servicer deems necessary or appropriate to confirm or carry out more fully the
intent and purpose of such Servicing Agreement and the duties, responsibilities
and obligations to be performed by the Servicer thereunder. Such modifications
may only be made if they are consistent with the REMIC Provisions, as evidenced
by an Opinion of Counsel. Prior to the issuance of any modification or
amendment, the Master Servicer shall deliver to the Trustee and the Trust
Administrator such Opinion of Counsel and an Officer's Certificate setting forth
(i) the provision that is to be modified or amended, (ii) the modification or
amendment that the Master Servicer desires to issue and (iii) the reason or
reasons for such proposed amendment or modification.

            (b) The Trustee and the Trust Administrator shall consent to any
amendment or supplement to a Servicing Agreement proposed by the Master Servicer
pursuant to Section 3.07(a), which consent and amendment shall not require the
consent of any Certificateholder if it is (i) for the purpose of curing any
mistake or ambiguity or to further effect or protect the rights of the
Certificateholders or (ii) for any other purpose, provided such amendment or
supplement for such other purpose cannot reasonably be expected to adversely
affect Certificateholders. The lack of reasonable expectation of an adverse
effect on Certificateholders may be established through the delivery to the
Trustee and the Trust Administrator of (i) an Opinion of Counsel to such effect
or (ii) written notification from each Rating Agency to the effect that such
amendment or supplement will not result in reduction of the current rating
assigned by that Rating Agency to the Certificates. Notwithstanding the two
immediately preceding sentences, either the Trustee or the Trust Administrator
may, in its discretion, decline to enter into or consent to any such supplement
or amendment if its own rights, duties or immunities shall be adversely
affected.

            (c)(i) Notwithstanding anything to the contrary in this Section
3.07, the Master Servicer from time to time may, without the consent of any
Certificateholder, the Trustee or the Trust Administrator, enter into an
amendment (A) to an Other Servicing Agreement for the purpose of (i) eliminating
or reducing Month End Interest and (ii) providing for the remittance of Full
Unscheduled Principal Receipts by the applicable Servicer to the Master Servicer
not later than the 24th day of each month (or if such day is not a Business Day,
on the previous Business Day) or (B) to the WFHM Servicing Agreement for the
purpose of changing the applicable Remittance Date to the 18th day of each month
(or if such day is not a Business Day, on the previous Business Day).

            (ii) The Master Servicer may direct WFHM to enter into an amendment
to the WFHM Servicing Agreement for the purposes described in Sections
3.07(c)(i)(B) and 10.01(b)(iii).

            SECTION 3.08 OVERSIGHT OF SERVICING.

            The Master Servicer shall supervise, monitor and oversee the
servicing of the Mortgage Loans by each Servicer and the performance by each
Servicer of all services, duties, responsibilities and obligations (including
the obligation to maintain an Errors and Omissions Policy and Fidelity Bond)
that are to be observed or performed by the Servicer under its respective
Servicing Agreement. In performing its obligations hereunder, the Master
Servicer shall act in a manner consistent with Accepted Master Servicing
Practices and with the Trustee's, the Trust Administrator's and the
Certificateholders' reliance on the Master Servicer, and in a manner consistent
with the terms and provisions of any insurance policy required to be maintained
by the Master Servicer or any Servicer pursuant to this Agreement or any
Servicing Agreement. The Master Servicer acknowledges that prior to taking
certain actions required to service the Mortgage Loans, each Servicing Agreement
provides that the Servicer thereunder must notify, consult with, obtain the
consent of or otherwise follow the instructions of the Master Servicer. The
Master Servicer is also given authority to waive compliance by a Servicer with
certain provisions of its Servicing Agreement. In each such instance, the Master
Servicer shall promptly instruct such Servicer or otherwise respond to such
Servicer's request. In no event will the Master Servicer instruct such Servicer
to take any action, give any consent to action by such Servicer or waive
compliance by such Servicer with any provision of such Servicer's Servicing
Agreement if any resulting action or failure to act would be inconsistent with
the requirements of the Rating Agencies that rated the Certificates or would
otherwise have an adverse effect on the Certificateholders. Any such action or
failure to act shall be deemed to have an adverse effect on the
Certificateholders if such action or failure to act either results in (i) the
downgrading of the rating assigned by any Rating Agency to the Certificates,
(ii) the loss by the Upper-Tier REMIC or the Lower-Tier REMIC of REMIC status
for federal income tax purposes or (iii) the imposition of any Prohibited
Transaction Tax or any federal taxes on either the Upper-Tier REMIC, the
Lower-Tier REMIC or the Trust Estate. The Master Servicer shall have full power
and authority in its sole discretion to take any action with respect to the
Trust Estate as may be necessary or advisable to avoid the circumstances
specified including clause (ii) or (iii) of the preceding sentence.

            For the purposes of determining whether any modification of a
Mortgage Loan shall be permitted by the Trust Administrator or the Master
Servicer, such modification shall be construed as a substitution of the modified
Mortgage Loan for the Mortgage Loan originally deposited in the Trust Estate if
it would be a "significant modification" within the meaning of Section
1.860G-2(b) of the regulations of the U.S. Department of the Treasury. No
modification shall be approved unless (i) the modified Mortgage Loan would
qualify as a Substitute Mortgage Loan under Section 2.02 and (ii) with respect
to any modification that occurs more than three months after the Closing Date
and is not the result of a default or a reasonably foreseeable default under the
Mortgage Loan, there is delivered to the Trust Administrator an Opinion of
Counsel (at the expense of the party seeking to modify the Mortgage Loan) to the
effect that such modification would not be treated as giving rise to a new debt
instrument for federal income tax purposes as described in the preceding
sentence.

            During the term of this Agreement, the Master Servicer shall consult
fully with each Servicer as may be necessary from time to time to perform and
carry out the Master Servicer's obligations hereunder and otherwise exercise
reasonable efforts to encourage such Servicer to perform and observe the
covenants, obligations and conditions to be performed or observed by it under
its Servicing Agreement.

            The relationship of the Master Servicer to the Trustee and the Trust
Administrator under this Agreement is intended by the parties to be that of an
independent contractor and not that of a joint venturer, partner or agent.

            The Master Servicer shall administer the Trust Estate on behalf of
the Trustee and shall have full power and authority, acting alone or (subject to
Section 6.06) through one or more subcontractors, to do any and all things in
connection with such administration which it may deem necessary or desirable.
Upon the execution and delivery of this Agreement, and from time to time as may
be required thereafter, the Trust Administrator, on behalf of the Trustee shall
furnish the Master Servicer or its subcontractors with any powers of attorney
and such other documents as may be necessary or appropriate to enable the Master
Servicer to carry out its administrative duties hereunder.

            The Seller shall be entitled to repurchase at its option (i) any
defaulted Mortgage Loan or any Mortgage Loan as to which default is reasonably
foreseeable from the Trust Estate if, in the Seller's judgment, the default is
not likely to be cured by the Mortgagor or (ii) any Mortgage Loan in the Trust
Estate which, pursuant to paragraph 5(b) of the Mortgage Loan Purchase
Agreement, WFHM requests the Seller to repurchase and to sell to WFHM to
facilitate the exercise of WFHM's rights against the originator or a prior
holder of such Mortgage Loan. The purchase price for any such Mortgage Loan
shall be 100% of the unpaid principal balance of such Mortgage Loan plus accrued
interest thereon at the Mortgage Interest Rate for such Mortgage Loan, through
the last day of the month in which such repurchase occurs. Upon the receipt of
such purchase price, the Master Servicer shall provide to the Trust
Administrator the certification required by Section 3.04 and the Trust
Administrator and the Custodian, if any, shall promptly release to the Seller
the Owner Mortgage Loan File relating to the Mortgage Loan being repurchased.

            In the event that (i) the Master Servicer determines at any time
that, notwithstanding the representations and warranties set forth in Section
2.03(b), any Mortgage Loan is not a "qualified mortgage" within the meaning of
Section 860G of the Code and (ii) the Master Servicer is unable to enforce the
obligation of the Seller to purchase such Mortgage Loan pursuant to Section 2.02
within two months of such determination, the Master Servicer shall cause such
Mortgage Loan to be auctioned to the highest bidder and sold out of the Trust
Estate no later than the date 90 days after such determination. In the event of
any such sale of a Mortgage Loan, the Trust Administrator shall, at the written
request of the Master Servicer and upon being supported with appropriate forms
therefor, within five Business Days of the deposit by the Master Servicer of the
proceeds of such auction into the Certificate Account, release or cause to be
released to the entity identified by the Master Servicer the related Owner
Mortgage Loan File and Servicer Mortgage Loan File and shall execute and deliver
such instruments of transfer or assignment, in each case without recourse, as
shall be necessary to vest in the auction purchaser title to the Mortgage Loan
and the Trust Administrator shall have no further responsibility with regard to
such Owner Mortgage Loan File or Servicer Mortgage Loan File. Neither the Trust
Administrator, the Master Servicer nor any Servicer, acting on behalf of the
Trust Administrator, shall provide financing from the Trust Estate to any
purchaser of a Mortgage Loan.

            The Master Servicer, on behalf of the Trust Administrator, shall,
pursuant to the Servicing Agreements, object to the foreclosure upon, or other
related conversion of the ownership of, any Mortgaged Property by the related
Servicer if (i) the Master Servicer believes such Mortgaged Property may be
contaminated with or affected by hazardous wastes or hazardous substances or
(ii) such Servicer does not agree to administer such Mortgaged Property, once
the related Mortgage Loan becomes an REO Mortgage Loan, in a manner which would
not result in a federal tax being imposed upon the Trust Estate or the
Upper-Tier REMIC or Lower-Tier REMIC.

            MLCC Additional Collateral may be liquidated and the proceeds
applied to cover any shortfalls upon the liquidation of a Mortgaged Property;
provided, however, that the Trust Estate in no event shall acquire ownership of
the MLCC Additional Collateral unless the Trust Administrator shall have
received an Opinion of Counsel that such ownership shall not cause the Trust
Estate to fail to qualify as two separate REMICs or subject either REMIC to any
tax.

            The Master Servicer may enter into a special servicing agreement
with an unaffiliated holder of 100% Percentage Interest of a Class of Class B
Certificates or a holder of a class of securities representing interests in the
Class B Certificates and/or other subordinated mortgage pass-through
certificates, such agreement to be substantially in the form of Exhibit M hereto
or subject to each Rating Agency's acknowledgment that the ratings of the
Certificates in effect immediately prior to the entering into of such agreement
would not be qualified, downgraded or withdrawn and the Certificates would not
be placed on credit review status (except for possible upgrading) (without, in
the case of the Class A-3 Certificates, giving effect to the guaranty provided
by Ambac) as a result of such agreement. Any such agreement may contain
provisions whereby such holder may instruct the Master Servicer to instruct a
Servicer to the extent provided in the applicable Servicing Agreement to
commence or delay foreclosure proceedings with respect to delinquent Mortgage
Loans and will contain provisions for the deposit of cash by the holder that
would be available for distribution to Certificateholders if Liquidation
Proceeds are less than they otherwise may have been had the Servicer acted in
accordance with its normal procedures.

            SECTION 3.09 TERMINATION AND SUBSTITUTION OF SERVICING
                         AGREEMENTS.

            Upon the occurrence of any event for which a Servicer may be
terminated pursuant to its Servicing Agreement, the Master Servicer shall
promptly deliver to the Seller and the Trustee an Officer's Certificate
certifying that an event has occurred which may justify termination of such
Servicing Agreement, describing the circumstances surrounding such event and
recommending what action should be taken by the Trustee with respect to such
Servicer. If the Master Servicer recommends that such Servicing Agreement be
terminated, the Master Servicer's certification must state that the breach is
material and not merely technical in nature. Upon written direction of the
Master Servicer, based upon such certification, the Trustee shall promptly
terminate such Servicing Agreement. Notwithstanding the foregoing, in the event
that (i) WFHM fails to make any advance, as a consequence of which the Trust
Administrator is obligated to make an advance pursuant to Section 3.03 and (ii)
the Trust Administrator provides WFHM written notice of the failure to make such
advance and such failure shall continue unremedied for a period of 15 days after
receipt of such notice, the Trust Administrator shall recommend to the Trustee
the termination of the WFHM Servicing Agreement without the recommendation of
the Master Servicer and upon such recommendation, the Trustee shall terminate
the WFHM Servicing Agreement. The Master Servicer shall indemnify the Trustee
and the Trust Administrator and hold each harmless from and against any and all
claims, liabilities, costs and expenses (including, without limitation,
reasonable attorneys' fees) arising out of, or assessed against the Trustee or
the Trust Administrator in connection with termination of such Servicing
Agreement at the direction of the Master Servicer. In addition, the Master
Servicer shall indemnify the Trustee and hold it harmless from and against any
and all claims, liabilities, costs and expenses (including, without limitation,
reasonable attorney's fees) arising out of, or assessed against the Trustee in
connection with the termination of the WFHM Servicing Agreement as provided in
the second preceding sentence. If the Trustee terminates such Servicing
Agreement, the Trustee may enter into a substitute Servicing Agreement with the
Master Servicer or, at the Master Servicer's nomination, with another mortgage
loan service company acceptable to the Trustee, the Trust Administrator, the
Master Servicer and each Rating Agency under which the Master Servicer or such
substitute servicer, as the case may be, shall assume, satisfy, perform and
carry out all liabilities, duties, responsibilities and obligations that are to
be, or otherwise were to have been, satisfied, performed and carried out by such
Servicer under such terminated Servicing Agreement. Until such time as the
Trustee enters into a substitute servicing agreement with respect to the
Mortgage Loans previously serviced by such Servicer, the Master Servicer shall
assume, satisfy, perform and carry out all obligations which otherwise were to
have been satisfied, performed and carried out by such Servicer under its
terminated Servicing Agreement. However, in no event shall the Master Servicer
be deemed to have assumed the obligations of a Servicer to advance payments of
principal and interest on a delinquent Mortgage Loan in excess of the Master
Servicer's independent Periodic Advance obligation under Section 3.03 of this
Agreement. As compensation for the Master Servicer of any servicing obligations
fulfilled or assumed by the Master Servicer, the Master Servicer shall be
entitled to any servicing compensation to which a Servicer would have been
entitled if the Servicing Agreement with such Servicer had not been terminated.

            SECTION 3.10 APPLICATION OF NET LIQUIDATION PROCEEDS.

            For all purposes under this agreement, Net Liquidation Proceeds
received from a Servicer shall be allocated first to accrued and unpaid interest
on the related Mortgage Loan and then to the unpaid principal balance thereof.

            SECTION 3.11 ACT REPORTS.

            The Master Servicer shall, on behalf of the Seller, make all filings
required to be made by the Seller with respect to the Class A Certificates and
the Class I-B-1, Class I-B-2, Class I-B-3, Class II-B-1, Class II-B-2 and Class
I-B-3 Certificates pursuant to the Securities Exchange Act of 1934, as amended.

      receive distributions in respect of principal in an amount equal to the
      amount of principal distributed to its respective Corresponding Upper-Tier
      Class, Classes, Component or Components as provided herein. On each
      Distribution Date, each Uncertificated Lower-Tier Interest shall receive
      distributions in respect of interest equal to the Interest Accrual Amounts
      and distributions in respect of Unpaid Interest Shortfalls, as the case
      may be, in respect of its Corresponding Upper-Tier Class, Classes,
      Component or Components in each case to the extent actually distributed
      thereon. Such amounts distributed to the Uncertificated Lower-Tier
      Interests in respect of principal and interest with respect to any
      Distribution Date are referred to herein collectively as the "Lower-Tier
      Distribution Amount."

            As of any date, the principal balance of each Uncertificated
Lower-Tier Interest equals the Principal Balances of the respective
Corresponding Upper-Tier Class, Classes, Component or Components. The initial
principal balance of each Uncertificated Lower-Tier Interest equals the Original
Principal Balances of the respective Corresponding Upper-Tier Class, Classes,
Component or Components.

            The pass-through rate with respect to the Class I-A-L1 Interest,
Class I-A-L2 Interest, Class A-I-A-LUR Interest, Class II-A-L1 Interest, Class
I-B-L Interest, and Class II-B-L Interest shall be 7.750% per annum. The
pass-through rate for the Class I-A-L3 Interest and Class II-A-L3 Interest shall
be 7.69% per annum. The Class I-A-LPO and Class II-A-LPO Interests are
principal-only interests and are not entitled to distributions of interest. Any
Non-Supported Interest Shortfalls will be allocated to each Uncertificated
Lower-Tier Interest in the same relative proportions as interest is allocated to
such Uncertificated Lower-Tier Interest.

            (b) (i) On each Distribution Date prior to the applicable Cross-Over
Date, the Group I-A Non-PO Principal Distribution Amount will be allocated and
distributed in reduction of the Principal Balances of the Group I-A Certificates
and Components (other than the Principal Balance of the Class I-A-PO
Certificates) as follows:

            first, concurrently, to the Class I-A-R and Class I-A-LR
Certificates, pro rata, until the Principal Balance of each such Class has been
reduced to zero;

            second, commencing on the Distribution Date in June 2003,

Component, pro rata, based on their initial Principal Balances, until the
Principal Balance of each such Component has been reduced to zero;

            third, to the Class I-A-7 Certificates, the lesser of (i) the Class
I-A-7 Priority Amount and (ii) 98.6% of the Class A Non-PO Principal
Distribution Amount for the Group I-A Certificates and Components;

            fourth,   to  the  Class  I-A-1   Certificates,   until  the

Certificates, pro rata, until the Principal Balance of each such Class has been
reduced to zero;

            sixth, concurrently, to the Class I-A-3 Component and the Class
I-A-4 PO Component, pro rata, based on their initial Principal Balances, until
the Principal Balance of each such Component has been reduced to zero; and

            seventh, to the Class I-A-7 Certificates, without regard to the
amount calculated pursuant to priority third for such Distribution Date, until
the Principal Balance thereof has been reduced to zero.

               (ii) On each Distribution Date prior to the applicable Cross-Over
      Date, the Group II-A Non-PO Principal Distribution Amount will be
      allocated and distributed in reduction of the Principal Balances of the
      Classes of Group II-A Certificates and Components (other than the
      Principal Balance of the Class II-A-PO Certificates) as follows:

            first, commencing on the Distribution Date in June 2003, $16,332.40,
concurrently, to the Class II-A-3 Component and the Class II-A-4 PO Component,
pro rata, based on their initial Principal Balances, until the Principal Balance
of each such Component has been reduced to zero;

            second, to the Class II-A-2 Certificates, the lesser of (i) the
Class II-A-2 Priority Amount and (ii) 98.6% of the Class A Non-PO Principal
Distribution Amount for the Group II-A Certificates and Components;

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

            fourth, concurrently, to the Class II-A-3 Component and the Class
II-A-4 PO Component, pro rata, based on their initial Principal Balances, until
the Principal Balance of each such Component has been reduced to zero; and

            fifth, to the Class II-A-2 Certificates, without regard to the
amount calculated pursuant to priority second for such Distribution Date, until
the Principal Balance thereof has been reduced to zero.

            (c) Notwithstanding the foregoing, on each Distribution Date
occurring on or subsequent to the applicable Cross-Over Date, (x) the Group I-A
Non-PO Principal Distribution Amount shall be distributed among the Group I-A
Certificates and Components (other than the Class I-A-PO Certificates) and (y)
the Group II-A Non-PO Principal Distribution Amount shall be distributed among
the Group II-A Certificates and Components (other than the Class II-A-PO
Certificates) pro rata in accordance with their outstanding Principal Balances
without regard to either the proportions or the priorities set forth in Section
4.01(b)(i) and (ii).

            (d) (i) For purposes of determining whether the Classes of Class B
Certificates of a Group are eligible to receive distributions of principal with
respect to any Distribution Date, the following tests shall apply:

            (A) (i) if the Current Class I-B-1 Fractional Interest is less than

Group entitled to receive distributions of principal would reduce the Principal
Balances of the Classes of Class B Certificates of such Group entitled to
receive distributions of principal below zero, first the Group I Class B
Prepayment Percentage or the Group II Class B Prepayment Percentage, as the case
may be, of any affected Class of Class B Certificates for such Distribution Date
beginning with the affected Class of such Group with the lowest numerical Class
designation and then, if necessary, the Group I Class B Percentage or Group II
Class B Percentage, as the case may be, of such Class of the Class B
Certificates for such Distribution Date shall be reduced to the respective
percentages necessary to bring the Principal Balance of such Class of Class B
Certificates to zero. The Group I Class B Prepayment Percentages or the Group II
Class B Prepayment Percentages, as the case may be, and the Group I Class B
Percentages or the Group II Class B Percentages, as the case may be, of the
remaining Classes of Class B Certificates in the related Group will be
recomputed substituting for the Group I Subordinated Prepayment Percentage or
Group II Subordinated Prepayment Percentage, as the case may be, and Group I
Subordinated Percentage or Group II Subordinated Percentage, as the case may be,
in such computations the difference between (A) the Group I Subordinated
Prepayment Percentage or Group II Subordinated Prepayment Percentage, as the
case may be, or Group I Subordinated Percentage or Group II Subordinated
Percentage, as the case may be, and (B) the percentages determined in accordance
with the preceding sentence necessary to bring the Principal Balances of the
affected Classes of Class B Certificates of such Group to zero; provided,
however, that if the Principal Balances of all the Classes of Class B
Certificates in the related Group eligible to receive distributions of principal
shall be reduced to zero on such Distribution Date, the Group I Class B
Prepayment Percentage or Group II Class B Prepayment Percentage, as the case may
be, and Group I Class B Percentage or Group II Class B Percentage, as the case
may be, of the Class of Class B Certificates in such Group with the lowest
numerical Class designation which would otherwise be ineligible to receive
distributions of principal in accordance with this Section shall equal the
remainder of the Group I Subordinated Prepayment Percentage or Group II
Subordinated Prepayment Percentage, as applicable for such Distribution Date
minus the sum of the Group I Class B Prepayment Percentages or Group II Class B
Prepayment Percentages of the Classes of Class B Certificates in such Group
having lower numerical Class designations, if any, and the remainder of the
Group I Subordinated Percentage or Group II Subordinated Percentage, as the case
may be, for such Distribution Date minus the sum of the Group I Class B
Percentages or Group II Class B Percentages, as applicable of the Classes of
Class B Certificates in such Group having lower numerical Class designations, if
any, respectively. Any entitlement of any Class of Class B Certificates to
principal payments solely pursuant to this clause (ii) shall not cause such
Class to be regarded as being eligible to receive principal distributions for
the purpose of applying the definition of its Group I Class B Percentage or
Group II Class B Percentage, as applicable or Group II Class B Prepayment
Percentage or Group II Class B Prepayment Percentage, as applicable.

            (e) The Trust Administrator shall establish and maintain the
Upper-Tier Certificate Account, which shall be a separate trust account and an
Eligible Account. On each Distribution Date other than the Final Distribution
Date (if such Final Distribution Date is in connection with a purchase of the
assets of the Trust Estate by the Seller), the Paying Agent shall, on behalf of
the Master Servicer, from funds available on deposit in the Payment Account, (i)
deposit, in immediately available funds, by wire transfer or otherwise, into the
Upper-Tier Certificate Account the Lower-Tier Distribution Amount and (ii)
distribute to the Class I-A-LR Certificateholder (other than as provided in
Section 9.01 respecting the final distribution to Certificateholders) by check
mailed to such Holder at the address of such Holder appearing in the Certificate
Register, the Group I-A Distribution Amount with respect to the Class I-A-LR
Certificate and all other amounts distributable to the Class I-A-LR Certificate.
The Trust Administrator may clear and terminate the Upper-Tier Certificate
Account pursuant to Section 9.01.

            (f) On each Distribution Date other than the Final Distribution Date
(if such Final Distribution Date is in connection with a purchase of the assets
of the Trust Estate by the Seller), the Paying Agent shall, on behalf of the
Master Servicer, from funds remitted to it by the Master Servicer, distribute to
each Certificateholder of record (other than the Class I-A-LR Certificateholder)
on the preceding Record Date (other than as provided in Section 9.01 respecting
the final distribution to Certificateholders or in the last paragraph of this
Section 4.01(f) respecting the final distribution in respect of any Class)
either in immediately available funds by wire transfer to the account of such
Certificateholder at a bank or other entity having appropriate facilities
therefor, if such Certificateholder holds Certificates having a Denomination at
least equal to that specified in Section 11.19, and has so notified the Master
Servicer or, if applicable, the Paying Agent at least seven Business Days prior
to the Distribution Date or, if such Holder holds Certificates having, in the
aggregate, a Denomination less than the requisite minimum Denomination or if
such Holder holds the Class I-A-R Certificate or has not so notified the Paying
Agent, by check mailed to such Holder at the address of such Holder appearing in
the Certificate Register, such Holder's share of the Group I-A Distribution
Amount or Group II-A Distribution Amount, as applicable, with respect to each
Class of Class A Certificates (other than the Class A-3 and Class I-A-LR
Certificates), and the Group I-B Distribution Amount or Group II-B Distribution
Amount with respect to each Class of Class B Certificates (and, in the case of
the Class A-3 Certificates, as provided in Section 4.07).

            In the event that, on any Distribution Date prior to the Final
Distribution Date, the Principal Balance of any Class of Class A Certificates
(other than the Class I-A-R or Class I-A-LR Certificates) or the Principal
Balance of any Class of Class B Certificates would be reduced to zero, or in the
case of the Class A-5 Certificates, the Class A-5 Notional Amount would be
reduced to zero, the Master Servicer shall, as soon as practicable after the
Determination Date relating to such Distribution Date, send a notice to the
Trust Administrator. The Trust Administrator will then send a notice to each
Certificateholder of such Class with a copy to the Certificate Registrar,
specifying that the final distribution with respect to such Class will be made
on such Distribution Date only upon the presentation and surrender of such
Certificateholder's Certificates at the office or agency of the Trust
Administrator therein specified; provided, however, that the failure to give
such notice will not entitle a Certificateholder to any interest beyond the
interest payable with respect to such Distribution Date in accordance with
Section 4.01(a).

            (g) The Paying Agent (or if no Paying Agent is appointed by the
Master Servicer, the Master Servicer) shall withhold or cause to be withheld
such amounts as may be required by the Code (giving full effect to any
exemptions from withholding and related certifications required to be furnished
by Certificateholders and any reductions to withholding by virtue of any
bilateral tax treaties and any applicable certification required to be furnished
by Certificateholders with respect thereto) from distributions to be made to
Persons other than U.S. Persons ("Non-U.S. Persons"). Amounts withheld pursuant
to this Section 4.01(g) shall be treated as having been distributed to the
related Certificateholder for all purposes of this Agreement. For the purposes
of this paragraph, a "U.S. Person" is a citizen or resident of the United
States, a corporation or partnership (unless, in the case of a partnership,
Treasury regulations are adopted that provide otherwise) created or organized in
or under the laws of the United States, any state thereof or the District of
Columbia, including an entity treated as a corporation or partnership for
federal income tax purposes, an estate whose income is subject to United States
federal income tax regardless of its source, or a trust if a court within the
United States is able to exercise primary supervision over the administration of
such trust, and one or more such U.S. Persons have the authority to control all
substantial decisions of such trust (or, to the extent provided in applicable
Treasury regulations, certain trusts in existence on August 20, 1996 which are
eligible to elect to be treated as U.S. Persons).

            (ii) With respect to any Distribution Date, the principal portion of

            (b) With respect to any Distribution Date, the principal portion of
Excess Special Hazard Losses, Excess Fraud Losses and Excess Bankruptcy Losses
occurring with respect to any Group I Mortgage Loan or Group II Mortgage Loan
allocable to the Class I-A-PO or Class II-A-PO Certificates, respectively, will

or Group II-A Non-PO Principal Balance in the case of such Group I-A
Certificates and Components or Group II-A Certificates and Components and the
Principal Balance of each Class of the Group I-B Certificates or Group II-B

            (c) Any Realized Losses allocated to a Class of Class A Certificates
or Class B Certificates pursuant to Section 4.02(a) or Section 4.02(b) shall be

Components and the Group I Premium Payment based on each Class's or Components
Group I-A Interest Percentage and, in the case of the Group I Premium Payment,
the Group I Premium Percentage. Any such loss allocated to the Group II-A

among the outstanding Group II-A Certificates and Components and the Group II
Premium Payment based on each Class's or Component's Group II-A Interest
Percentage and, in the case of the Group II Premium Payment, the Group II
Premium Percentage. Any such loss allocated to the Class B Certificates of a
Group will be allocated among the outstanding of Classes of Class B Certificates
of such Group based on their Class B Interest Percentages. In addition, after
the Group I-B Principal Balance or Group II-B Principal Balance has been reduced
to zero, the interest portion of Realized Losses for the related Loan Group
(other than Excess Special Hazard Losses, Excess Fraud Losses and Excess
Bankruptcy Losses for such Loan Group) occurring with respect to any Mortgage
Loan in such Loan Group will be allocated among the outstanding Group I-A
Certificates and Components and the Group I Premium Payment or Group II-A

            (g) With respect to any Distribution Date, the principal portion of
Realized Losses and recoveries attributable to previously allocated Realized
Losses allocated pursuant to this Section 4.02 will be allocated to each
Uncertificated Lower-Tier Interest in an amount equal to the amount allocated to
its respective Corresponding Upper-Tier Class, Classes, Component or Components
as provided above.

            With respect to any Distribution Date, the interest portion of
Realized Losses allocated pursuant to this Section 4.02 will be allocated to
each Uncertificated Lower-Tier Interest in the same relative proportions as
interest is allocated to such Uncertificated Lower-Tier Interest.

            SECTION 4.03 PAYING AGENT.

      Certificateholders or otherwise disposed of as herein provided;

               (ii)     give  the  Trust  Administrator  notice  of  any

to its withdrawal or order from time to time. The amount of any losses incurred
in respect of any such investments shall be deposited in the Payment Account by
the Master Servicer out of its own funds immediately as realized. The Paying
Agent may withdraw from the Payment Account any amount deposited in the Payment

               (xxii) the amount of the aggregate Servicing Fees and Master
      Servicing Fees paid (and not previously reported) with respect to the
      related Distribution Date and the amount by which the aggregate Available
      Master Servicer Compensation for each Loan Group has been reduced by the
      Prepayment Interest Shortfall for such Loan Group for the related
      Distribution Date;

               (xxiii) in the case of the Class A-5 Certificates, the Class
      I-A-5 IO Component Notional Amount and the Class II-A-5 IO Notional
      Amount, if any;

               (xxiv)   the  Class  I-A-PO  Deferred  Amount  and  Class
      II-A-PO Deferred Amount, if any;

               (xxv) in the case of the Class A-3 Certificates, (a) the Class
      A-3 Distribution Deficiency, if any, for such Distribution Date, (b)
      amounts, if any, in respect of the Class A-3 Distribution Deficiency paid
      under the Policy and (c) the amounts attributable to the Class A-3

               (xxvi) in the case of the Class A-3 Certificates, the amount
      remaining in the Reserve Fund after taking into account the Reserve
      Withdrawal for such Distribution Date; and

               (xxvii) such other customary information as the Master Servicer
      deems necessary or desirable to enable Certificateholders to prepare their
      tax returns; and shall deliver a copy of each type of statement to the
      Trust Administrator, who shall provide copies thereof to Persons making
      written request therefor at the Corporate Trust Office.

            In the case of information furnished with respect to a Class of
Class A Certificates pursuant to clauses (i) and (ii) above and with respect to
a Class of Class B Certificates pursuant to clauses (iii) and (iv) above, the
amounts shall be expressed as a dollar amount per Class A or Class B Certificate
(other than the Class I-A-R and Class I-A-LR Certificates) with a $1,000
Denomination, and as a dollar amount per Class I-A-R and Class I-A-LR
Certificate with a $100 Denomination.

            Within a reasonable period of time after the end of each calendar
year, the Master Servicer shall furnish or cause to be furnished to each Person
who at any time during the calendar year was the Holder of a Certificate a
statement containing the information set forth in clauses (i) and (ii)(a) above
in the case of a Class A Certificateholder and the information set forth in
clauses (iii) and (iv)(a) above in the case of a Class B Certificateholder
aggregated for such calendar year or applicable portion thereof during which
such Person was a Certificateholder. Such obligation of the Master Servicer
shall be deemed to have been satisfied to the extent that substantially
comparable information shall be provided by the Master Servicer pursuant to any
requirements of the Code from time to time in force.

            Prior to the close of business on the third Business Day preceding
each Distribution Date, the Master Servicer shall furnish a statement to the
Trust Administrator, any Paying Agent and the Seller (the information in such
statement to be made available to Certificateholders by the Master Servicer on
written request) setting forth the Group I-A Distribution Amount or Group II-A
Distribution Amount, as applicable, with respect to each Class of Class A
Certificates and the Group I-B Distribution Amount and Group II-B distribution
Amount with respect to each Class of Class B Certificates. Upon receipt of any
such statement, the Trust Administrator shall promptly forward a copy of such
statement to Ambac. The determination by the Master Servicer of such amounts
shall, in the absence of obvious error, be presumptively deemed to be correct
for all purposes hereunder and the Trust Administrator and the Paying Agent
shall be protected in relying upon the same without any independent check or
verification.

            In addition to the reports required pursuant to this Section 4.04,
the Master Servicer shall make available upon request to each Holder and each
proposed transferee of a Class I-B-4, Class I-B-5, Class I-B-6, Class II-B-4,
Class II-B-5 or Class II-B-6 Certificate such additional information, if any, as
may be required to permit the proposed transfer to be effected pursuant to Rule
144A.

            SECTION 4.05 REPORTS TO MORTGAGORS AND THE INTERNAL
                         REVENUE SERVICE.

            The Master Servicer shall, in each year beginning after the Cut-Off
Date, make the reports of foreclosures and abandonments of any Mortgaged
Property as required by Code Section 6050J. In order to facilitate this
reporting process, the Master Servicer shall request that each Servicer, on or
before January 15th of each year, shall provide to the Internal Revenue Service,
with copies to the Master Servicer, reports relating to each instance occurring
during the previous calendar year in which such Servicer (i) on behalf of the
Trustee acquires an interest in a Mortgaged Property through foreclosure or
other comparable conversion in full or partial satisfaction of a Mortgage Loan
serviced by such Servicer, or (ii) knows or has reason to know that a Mortgaged
Property has been abandoned. Reports from the Servicers shall be in form and
substance sufficient to meet the reporting requirements imposed by Code Section
6050J. In addition, each Servicer shall provide the Master Servicer with
sufficient information to allow the Master Servicer to, for each year ending
after the Cut-Off Date, provide, or cause to be provided, to the Internal
Revenue Service and the Mortgagors such information as is required under Code
Sections 6050H (regarding payment of interest) and 6050P (regarding cancellation
of indebtedness).

            SECTION 4.06 RESERVE FUND.

            (a) A separate Reserve Fund shall be established on the Closing Date
for the Class A-3 Certificates. The Reserve Fund shall be maintained by the
Trust Administrator in accordance with this Section 4.06. At the time the
Reserve Fund is established, the Seller shall cause to be deposited into the
Reserve Fund the amount of $3,000.00.

            With respect to each Distribution Date, the applicable Reserve
Withdrawal shall be withdrawn by the Trust Administrator from the amount on
deposit in the Reserve Fund in accordance with this Section 4.06 and distributed
on such Distribution Date to the Holders of the Class A-3 Certificates, pro
rata, based on Percentage Interest.

            Notwithstanding anything herein to the contrary, on the Distribution
Date on which the Principal Balance of the Class A-3 Certificates has been
reduced to zero, any funds then on deposit in the Reserve Fund shall be
distributed to Lehman Brothers at the address provided by it to the Trust
Administrator.

            (b) The Reserve Fund will be an "outside reserve fund" under the
REMIC Provisions that is beneficially owned for federal income tax purposes by
Lehman Brothers, which shall report all income, gain, deduction or loss with
respect thereto, and will not be an asset of either REMIC.

            SECTION 4.07 DISTRIBUTIONS IN REDUCTION OF THE CLASS
                         A-3 CERTIFICATES.

            Distributions in reduction of the Principal Balance of the Class A-3
Certificates will be made in integral multiples of $1,000 at the request of the
appropriate representatives of Deceased Holders of such Class and at the request
of Living Holders of such Class or by mandatory distributions by random lot,
pursuant to clauses (a) and (d) below, or on a pro rata basis pursuant to clause
(f) below.

            (a) On each Distribution Date on which distributions in reduction of
the Principal Balance of the Class A-3 Certificates are made, such distributions
will be made with respect to such Class in the following priority:

               (i)any request by the personal representatives of a Deceased
      Holder or by a surviving tenant by the entirety, by a surviving joint
      tenant or by a surviving tenant in common, but not exceeding an aggregate
      principal balance for such Class of $100,000 per request; and

               (ii)     any  request  by  a  Living   Holder,   but  not
      exceeding  an  aggregate  principal  balance  for  such  Class  of
      $10,000 per request.

            Thereafter, distributions will be made, with respect to such Class,
as provided in clauses (i) and (ii) above up to a second $100,000 and $10,000,
respectively. This sequence of priorities will be repeated for each request for
principal distributions for such Class made by the Beneficial Owners of the
Class A-3 Certificates until all such requests have been honored.

            For each such sequence of priorities described above, requests for
distributions in reduction of the principal balance of Class A-3 Certificates
presented on behalf of Deceased Holders in accordance with the provisions of
clause (i) above will be accepted in order of their receipt by the Clearing
Agency and requests for distributions in reduction of the principal balance of
Class A-3 Certificates presented by Living Holders in accordance with the
provisions of clause (ii) above will be accepted in the order of their receipt
by the Clearing Agency after all requests with respect to such Class presented
in accordance with clause (i) have been honored. All requests for distributions
in reduction of the principal balance of the Class A-3 Certificates will be
accepted in accordance with the provisions set forth in Section 4.07(c). All
requests for distributions in reduction of the principal balance of Class A-3
Certificates with respect to any Distribution Date must be received by the
Clearing Agency and forwarded to, and received by, the Trust Administrator no
later than the close of business on the related Record Date. Requests for
distributions which are received by the Clearing Agency and forwarded to, and
received by, the Trust Administrator after the related Record Date and requests,
in either case, for distributions not accepted with respect to any Distribution
Date, will be treated as requests for distributions in reduction of the
principal balance of Class A-3 Certificates on the next succeeding Distribution
Date, and each succeeding Distribution Date thereafter, until each such request
is accepted or is withdrawn as provided in Section 4.07(c). Such requests as are
not so withdrawn shall retain their order of priority without the need for any
further action on the part of the appropriate Beneficial Owner of the related
Class A-3 Certificate, all in accordance with the procedures of the Clearing
Agency and the Trust Administrator. Upon the transfer of beneficial ownership of
any Class A-3 Certificate, any distribution request previously submitted with
respect to such Certificate will be deemed to have been withdrawn only upon the
receipt by the Trust Administrator of notification of such withdrawal in the
manner required by the Clearing Agency under its APUT System.

            Distributions in reduction of the principal balance of the Class A-3
Certificates will be applied, in the aggregate with respect to such Class, in an
amount equal to the sum of (x) the Group I-A Non-PO Principal Distribution
Amount allocable to the Class I-A-3 Component pursuant to Section 4.01(b) and
(y) the Group II-A Non-PO Principal Distribution Amount allocable to the Class
II-A-3 Component pursuant to Section 4.01(b), plus any amounts distributable to
the Class A-3 Certificates as a payment under the Policy of a Class A-3
Principal Loss Amount of the type described in clause (i) of the definition
thereof, minus amounts to repay any funds withdrawn from the Rounding Account
for such Class for the prior Distribution Date, plus any amounts available for
distribution from the Rounding Account for such Class established as provided in
Section 4.07(e), provided that the aggregate distribution in reduction of the
Principal Balance of such Class on any Distribution Date is made in an integral
multiple of $1,000.

            To the extent that the portion of the Group I-A Non-PO Principal
Distribution Amount and the Group II-A Non-PO Principal Distribution Amount
allocable to distributions in reduction of the Principal Balance of the Class
I-A-3 and Class II-A-3 Components on any Distribution Date plus any amounts
distributable to the Class A-3 Certificates as a payment under the Policy of a
Class A-3 Principal Loss Amount of the type described in clause (i) of the
definition thereof (minus amounts to repay any funds withdrawn from the Rounding
Account for such Class on the prior Distribution Date and plus any amounts
required to be distributed from the Rounding Account for such Class pursuant to
Section 4.07(e)) exceeds the aggregate principal balance of Class A-3
Certificates with respect to which distribution requests, as set forth above,
have been received, distributions in reduction of the Principal Balance of the
Class A-3 Certificates will be made by mandatory distribution pursuant to
Section 4.07(d).

            (b) A Class A-3 Certificate shall be deemed to be held by a Deceased
Holder for purposes of this Section 4.07 if the death of the Beneficial Owner
thereof is deemed to have occurred. Class A-3 Certificates beneficially owned by
tenants by the entirety, joint tenants or tenants in common will be considered
to be beneficially owned by a single owner. The death of a tenant by the
entirety, joint tenant or tenant in common will be deemed to be the death of the
Beneficial Owner, and the Class A-3 Certificates so beneficially owned will be
eligible for priority with respect to distributions in reduction of the
principal balance of such Class thereof, subject to the limitations stated
above. Class A-3 Certificates beneficially owned by a trust will be considered
to be beneficially owned by each beneficiary of the trust to the extent of such
beneficiary's beneficial interest therein, but in no event will a trust's
beneficiaries collectively be deemed to be Beneficial Owners of a number of
Individual Class A-3 Certificates greater than the number of Individual Class
A-3 Certificates of which such trust is the owner. The death of a beneficiary of
a trust will be deemed to be the death of a Beneficial Owner of the Class A-3
Certificates owned by the trust to the extent of such beneficiary's beneficial
interest in such trust. The death of an individual who was a tenant by the
entirety, joint tenant or tenant in common in a tenancy which is the beneficiary
of a trust will be deemed to be the death of the beneficiary of such trust. The
death of a person who, during his or her lifetime, was entitled to substantially
all of the beneficial ownership interests in Individual Class A-3 Certificates
will be deemed to be the death of the Beneficial Owner of such Class A-3
Certificates regardless of the registration of ownership, if such beneficial
interest can be established to the satisfaction of the Trust Administrator. Such
beneficial interest will be deemed to exist in typical cases of street name or
nominee ownership, ownership by a trustee, ownership under the Uniform Gifts to
Minors Act and community property or other joint ownership arrangements between
a husband and wife. Beneficial interests shall include the power to sell,
transfer or otherwise dispose of a Class A-3 Certificate and the right to
receive the proceeds therefrom, as well as interest and distributions in
reduction of the principal balance of the Class A-3 Certificates payable with
respect thereto. The Trust Administrator shall not be under any duty to
determine independently the occurrence of the death of any deceased Beneficial
Owner. The Trust Administrator may rely entirely upon documentation delivered to
it pursuant to Section 4.07(c) in establishing the eligibility of any Beneficial
Owner to receive the priority accorded Deceased Holders in Section 4.07(a).

            (c) Requests for distributions in reduction of the principal balance
of Class A-3 Certificates must be made by delivering a written request therefor
to the Clearing Agency Participant or Clearing Agency Indirect Participant that
maintains the account evidencing such Beneficial Owner's interest in Class A-3
Certificates. In the case of a request on behalf of a Deceased Holder,
appropriate evidence of death and any tax waivers are required to be forwarded
to the Trust Administrator under separate cover. The Clearing Agency Participant
should in turn make the request of the Clearing Agency (or, in the case of a
Clearing Agency Indirect Participant, such Clearing Agency Indirect Participant
must notify the related Clearing Agency Participant of such request, which
Clearing Agency Participant should make the request of the Clearing Agency) in
the manner required under the rules and regulations of the Clearing Agency's
APUT System and provided to the Clearing Agency Participant. Upon receipt of
such request, the Clearing Agency will date and time stamp such request and
forward such request to the Trust Administrator. The Clearing Agency may
establish such procedures as it deems fair and equitable to establish the order
of receipt of requests for such distributions received by it on the same day.
Neither the Master Servicer nor the Trust Administrator shall be liable for any
delay in delivery of requests for distributions or withdrawals of such requests
by the Clearing Agency, a Clearing Agency Participant or any Clearing Agency
Indirect Participant.

            The Trust Administrator shall maintain a list of those Clearing
Agency Participants representing the appropriate Beneficial Owners of Class A-3
Certificates that have submitted requests for distributions in reduction of the
principal balance of Certificates of such Class, together with the order of
receipt and the amounts of such requests. The Clearing Agency will honor
requests for distributions in the order of their receipt (subject to the
priorities described in Section 4.07(a) above). The Trust Administrator shall
notify the Clearing Agency and the appropriate Clearing Agency Participants as
to which requests should be honored on each Distribution Date. Requests shall be
honored by the Clearing Agency in accordance with the procedures, and subject to
the priorities and limitations, described in this Section 4.07. The exact
procedures to be followed by the Trust Administrator and the Clearing Agency for
purposes of determining such priorities and limitations will be those
established from time to time by the Trust Administrator or the Clearing Agency,
as the case may be. The decisions of the Trust Administrator and the Clearing
Agency concerning such matters will be final and binding on all affected
persons.

            Individual Class A-3 Certificates which have been accepted for a
distribution shall be due and payable on the applicable Distribution Date. Such
Certificates shall cease to bear interest after the last day of the month
preceding the month in which such Distribution Date occurs, and notwithstanding
anything to the contrary herein, no amounts shall be due from Ambac or otherwise
with respect to interest on such Certificates after such last day of the month.

            Any Beneficial Owner of a Class A-3 Certificate which has requested
a distribution may withdraw its request by so notifying in writing the Clearing
Agency Participant or Clearing Agency Indirect Participant that maintains such
Beneficial Owner's account. In the event that such account is maintained by a
Clearing Agency Indirect Participant, such Clearing Agency Indirect Participant
must notify the related Clearing Agency Participant which in turn must forward
the withdrawal of such request, on a form required by the Clearing Agency, to
the Trust Administrator. If such notice of withdrawal of a request for
distribution has not been received by the Clearing Agency and forwarded to the
Trust Administrator on or before the Record Date for the next Distribution Date,
the previously made request for distribution will be irrevocable with respect to
the making of distributions in reduction of the Principal Balance of Class A-3
Certificates on such Distribution Date.

            In the event any requests for distributions in reduction of the
principal balance of Class A-3 Certificates are rejected by the Trust
Administrator for failure to comply with the requirements of this Section 4.07,
the Trust Administrator shall return such request to the appropriate Clearing
Agency Participant with a copy to the Clearing Agency with an explanation as to
the reason for such rejection.

            (d) To the extent, if any, that distributions in reduction of the
Principal Balance of Class A-3 Certificates on a Distribution Date exceed the
outstanding principal balances of Certificates of such Class with respect to
which distribution requests have been received by the related Record Date, as
provided in Section 4.07(a) above, distributions in reduction of the Principal
Balance of the Class A-3 Certificates will be made by mandatory distributions in
reduction thereof. Such mandatory distributions on Individual Class A-3
Certificates will be made by random lot in accordance with the then-applicable
random lot procedures of the Clearing Agency, the Clearing Agency Participants
and the Clearing Agency Indirect Participants representing the Beneficial
Owners; provided however, that, if after the distribution in reduction of the
Principal Balance of the Class A-3 Certificates on the next succeeding
Distribution Date on which mandatory distributions are to be made, the principal
balance of Class A-3 Certificates would not be reduced to zero, the Individual
Class A-3 Certificates to which such distributions will be applied shall be
selected by the Clearing Agency from those Class A-3 Certificates not otherwise
receiving distributions in reduction of the principal balance on such
Distribution Date. The Trust Administrator shall notify the Clearing Agency of
the aggregate amount of the mandatory distribution in reduction of the Principal
Balance of the Class A-3 Certificates to be made on the next Distribution Date.
The Clearing Agency shall then allocate such aggregate amount among its Clearing
Agency Participants on a random lot basis. Each Clearing Agency Participant and,
in turn, each Clearing Agency Indirect Participant will then select, in
accordance with its own random lot procedures, Individual Class A-3 Certificates
from among those held in its accounts to receive mandatory distributions in
reduction of the principal balance of the Certificates of such Class, such that
the total amount so selected is equal to the aggregate amount of such mandatory
distributions allocated to such Clearing Agency Participant by the Clearing
Agency and to such Clearing Agency Indirect Participant by its related Clearing
Agency Participant, as the case may be. Clearing Agency Participants and
Clearing Agency Indirect Participants which hold Class A-3 Certificates selected
for mandatory distributions in reduction of the principal balance are required
to provide notice of such mandatory distributions to the affected Beneficial
Owners. The Master Servicer agrees to notify the Trust Administrator of the
amount of distributions in reduction of the principal balance of Class A-3
Certificates to be made on each Distribution Date in a timely manner such that
the Trust Administrator may fulfill its obligations pursuant to the Letter of
Representations dated the Business Day immediately preceding the Closing Date
among the Seller, the Trust Administrator and the Clearing Agency.

            (e) On the Closing Date, the Rounding Account shall be established
with the Trust Administrator and the Seller shall cause to be initially
deposited with the Trust Administrator a $999.99 deposit for the Rounding
Account. On each Distribution Date on which a distribution is made in reduction
of the principal balance of the Class A-3 Certificates, funds on deposit in the
Rounding Account shall be available to be applied to round upward to an integral
multiple of $1,000 the aggregate distribution in reduction of the Class A
Principal Balance to be made on the Class A-3 Certificates. Rounding of such
distribution on the Class A-3 Certificates shall be accomplished, on the first
such Distribution Date, by withdrawing from the Rounding Account the amount of
funds, if any, needed to round the amount otherwise available for such
distribution in reduction of the principal balance of the Class A-3 Certificates
upward to the next integral multiple of $1,000. On each succeeding Distribution
Date on which distributions in reduction of the principal balance of the Class
A-3 Certificates are to be made, the aggregate amount of such distributions
allocable to the Class A-3 Certificates shall be applied first to repay any
funds withdrawn from the Rounding Account for such Class on the prior
Distribution Date for which funds were withdrawn from such account for such
Class, and then the remainder of such allocable amount, if any, shall be
similarly rounded upward and applied as distributions in reduction of the
principal balance of the Class A-3 Certificates; this process shall continue on
succeeding Distribution Dates until the Class A Principal Balance of the Class
A-3 Certificates has been reduced to zero. The funds in the Rounding Account
shall be held in a non-interest bearing account and shall not be reinvested.

            Notwithstanding anything herein to the contrary, on the Distribution
Date on which distributions in reduction of the Principal Balance of the Class
A-3 Certificates will reduce the Principal Balance thereof to zero or in the
event that distributions in reduction of the Principal Balance of the Class A-3
Certificates are made in accordance with the provisions set forth in Section
4.07(f), an amount equal to the difference between $1,000 and the sum then held
in the Rounding Account shall be paid from the Pool Distribution Amount to the
Rounding Account. Any funds then on deposit in such Rounding Account shall be
distributed to the Holder of the Class A-LR Certificate.

            (f) Notwithstanding any provisions herein to the contrary, on each
Distribution Date on and after Ambac's failure to make a payment with respect to
a Class A-3 Distribution Deficiency, distributions in reduction of the Principal
Balance of the Class A-3 Certificates (including amounts paid in respect of such
losses under the Policy) will be made on a pro rata basis among the Holders of
the Class A-3 Certificates and will not be made in integral multiples of $1,000
or pursuant to requested distributions or mandatory distributions by random lot.

            (g) In the event that the pro rata distributions described in
section 4.07(f) cannot be made through the facilities of the Clearing Agency,
the Class A-3 Certificates will be withdrawn from the facilities of the Clearing
Agency and Definitive Certificates will be issued to replace such withdrawn
Book-Entry Certificates pursuant to Section 5.07. An amendment to this
Agreement, which may be approved without the consent of any Certificateholders,
shall establish procedures relating to the manner in which pro rata
distributions in reduction of the principal balance of the Class A-3
Certificates are to be made; provided that such procedures shall be consistent,
to the extent practicable and customary for certificates similar to the Class
A-3 Certificates, with the provisions of this Section 4.07.

            SECTION 4.08 POLICY MATTERS.

            (a) If, on the second Business Day before any Distribution Date, the
Trust Administrator determines that there will be a Class A-3 Distribution
Deficiency for such Distribution Date, the Trust Administrator shall determine
the amount of such Class A-3 Distribution Deficiency and shall give notice to
Ambac by telephone or telecopy of the amount of such deficiency confirmed in
writing by the Notice of Nonpayment by 12:00 noon, New York City time on such
second Business Day.

            (b) At the time of the execution and delivery of this Agreement, the
Trust Administrator shall establish a separate special purpose trust account in
the name of the Trust Administrator for the benefit of Holders of the Class A-3
Certificates referred to herein as the "Policy Payments Account" over which the
Trust Administrator shall have exclusive control and sole right of withdrawal.
The Trust Administrator shall deposit any amounts paid under the Policy into the
Policy Payments Account and distribute such amounts only for purposes of payment
to Holders of the Class A-3 Certificates of the Class A-3 Distribution
Deficiency for which a claim was made and such amounts may not be applied to
satisfy any costs, expenses or liabilities of the Trust Administrator or the
Trust Estate. Amounts paid under the Policy shall be disbursed by the Trust
Administrator to Holders of the Class A-3 Certificates in the same manner as
distributions in reduction of the principal balance of and interest on the
Certificates of such Class are made under Section 4.01(e). It shall not be
necessary for such payments of the Class A-3 Distribution Deficiency to be made
by checks or wire transfers separate from the check or wire transfer used to pay
distributions in reduction of the principal balance of and interest on the Class
A-3 Certificates with funds available to make such distributions. However, the
amount of any distribution to be paid from funds transferred from the Policy
Payments Account shall be noted as provided in (c) below and in the statement to
be furnished to Holders of the Class A-3 Certificates and Ambac pursuant to
Section 4.04. Funds held in the Policy Payments Account shall not be invested by
the Trust Administrator.

            On any Distribution Date with respect to which a claim has been made
under the Policy, the amount of any funds received by the Trust Administrator as
a result of the claim under the Policy to the extent necessary to make
distributions on the Class A-3 Certificates equal to the Class A-3 Distribution
Deficiency on such Distribution Date shall be withdrawn from the Policy Payments
Account and applied by the Trust Administrator to the payment in full of the
Class A-3 Distribution Deficiency. Any funds deposited into the Policy Payments
Account in respect of the Class A-3 Certificates that are remaining therein on
the first Business Day following a Distribution Date after the Class A-3
Distribution Deficiency has been made to the Certificateholders of such Class
shall be remitted in immediately available funds to Ambac, pursuant to the
instructions of Ambac, by the end of such Business Day.

            (c) The Trust Administrator shall keep a complete and accurate
record of the Class A-3 Interest Loss Amount, the Class A-3 Principal Loss
Amount and any Non-Supported Interest Shortfall allocated to the Class A-3
Certificates once the Reserve Fund has been depleted, paid from moneys received
under the Policy. Ambac shall have the right to inspect such records at
reasonable times upon one Business Day's prior notice to the Trust
Administrator.

            (d) In the event that the Trust Administrator has received a
certified copy of an order of the appropriate court that any distributions in
reduction of the principal balance of or interest on a Class A-3 Certificate has
been avoided in whole or in part as a preference payment under applicable
bankruptcy law, the Trust Administrator shall so notify Ambac and shall comply
with the provisions of the applicable Policy to obtain payment by Ambac of such
avoided distribution, and shall, at the time it provides notice to Ambac,
notify, by mail to Holders of the Certificates of such Class that, in the event
that any Holder's distribution is so recovered, such Holder will be entitled to
payment pursuant to the terms of the applicable Policy, a copy of which shall be
made available by the Trust Administrator and the Trust Administrator shall
furnish to Ambac its records evidencing the distributions in reduction of the
principal balance of and interest (including any Non-Supported Interest
Shortfall described in Section 4.08(c)) on the Class A-3 Certificates, if any,
which have been made by the Trust Administrator and subsequently recovered from
Holders, and the dates on which such distributions were made. Such payment under
the applicable Policy shall be disbursed to the receiver, conservator,
debtor-in-possession or trustee in bankruptcy named in the order and not to the
Trust Administrator or any Class A-3 Certificateholder directly (unless such
Certificateholder has previously paid such amount to the receiver, conservator,
debtor-in-possession or trustee in bankruptcy named in the order, in which case
such payment shall be disbursed to the Trust Administrator for distribution to
such Certificateholder upon proof of such payment reasonably satisfactory to
Ambac).

            (e) The Trust Administrator shall promptly notify Ambac of any
proceeding or the institution of any action seeking the avoidance as a
preferential transfer under applicable bankruptcy, insolvency, receivership or
similar law (a "Preference Claim") of any distribution made with respect to the
Class A-3 Certificates as to which it has actual knowledge. Each Holder of a
Class A-3 Certificate, by its purchase of such Certificates and the Trust
Administrator hereby agree that Ambac (so long as no Ambac Default exists) may
at any time during the continuation of any proceeding relating to a Preference
Claim direct all matters relating to such Preference Claim, including, without
limitation, (i) the direction of any appeal of any order relating to any
Preference Claim and (ii) the posting of any surety, supersedeas or performance
bond pending any such appeal. In addition and without limitation of the
foregoing, Ambac shall be subrogated to the rights of the Trust Administrator
and each Holder in the conduct of any Preference Claim, including, without
limitation, all rights of any party to an adversary proceeding or action with
respect to any court order issued in connection with any such Preference Claim.

            (f) The Trust Administrator acknowledges, and each Holder of a Class
A-3 Certificate by its acceptance of such Certificate agrees, that without any

Non-Supported Interest Shortfalls allocated to such Certificates and recoveries,
if any, with respect to the Class A-3 Principal Loss Amounts with respect to

            (g) The Master Servicer shall designate an Ambac Contact Person who

                                THE CERTIFICATES

            SECTION 5.01 THE CERTIFICATES.

            (a) The Class A and Class B Certificates shall be issued only in
minimum Denominations of a Single Certificate and, except for the Class A-5,
Class I-A-R and Class I-A-LR Certificates, integral multiples of $1,000 in
excess thereof (except, if necessary, for one Certificate of each Class (other
than the Class A-5, Class I-A-R and Class I-A-LR Certificates) that evidences
one Single Certificate plus such additional principal portion as is required in
order for all Certificates of such Class to equal the aggregate Original
Principal Balance of such Class, as the case may be), and shall be substantially
in the respective forms set forth as Exhibits A-I-A-1, A-I-A-2, A-I-A-6,
A-I-A-7, A-I-A-R, A-I-A-LR, A-I-A-PO, A-II-A-1, A-II-A-2, A-II-A-PO, A-A-3,
A-A-4, A-A-5, I-B-1, I-B-2, I-B-3, I-B-4, I-B-5, I-B-6, II-B-1, II-B-2, II-B-3,
II-B-4, II-B-5, II-B-6 and C (reverse side of Certificates) hereto. On original
issue the Certificates shall be executed and delivered by the Trust
Administrator to or upon the order of the Seller upon receipt by the Trust
Administrator or the Custodian of the documents specified in Section 2.01. The
aggregate principal portion (or notional amount) evidenced by the Class A and
Class B Certificates shall be the sum of the amounts specifically set forth in
the respective Certificates. The Certificates shall be executed by manual or
facsimile signature on behalf of the Trust Administrator by any Responsible
Officer thereof. Certificates bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Trust Administrator
shall bind the Trust Administrator notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and
delivery of such Certificates or did not hold such offices at the date of such
Certificates. No Certificate shall be entitled to any benefit under this
Agreement, or be valid for any purpose, unless manually countersigned by a
Responsible Officer of the Trust Administrator, or unless there appears on such
Certificate a certificate of authentication executed by the Authenticating Agent
by manual signature, and such countersignature or certificate upon a Certificate
shall be conclusive evidence, and the only evidence, that such Certificate has
been duly authenticated and delivered hereunder. All Certificates shall be dated
the date of their authentication.

            Until such time as Definitive Certificates are issued pursuant to
Section 5.07, each Book-Entry Certificate shall bear the following legend:

            "Unless this certificate is presented by an authorized
representative of [the Clearing Agency] to the Seller or its agent for
registration of transfer, exchange or payment, and any certificate issued is
registered in the name of [the Clearing Agency] or such other name as requested
by an authorized representative of [the Clearing Agency] and any payment is made
to [the Clearing Agency], any transfer, pledge or other use hereof for value or
otherwise by or to any person is wrongful since the registered owner hereof,
[the Clearing Agency], has an interest herein."

            (b) Upon original issuance, the Book-Entry Certificates shall be
issued in the form of one or more typewritten certificates, to be delivered to
The Depository Trust Company, the initial Clearing Agency, by, or on behalf of,
the Seller or to, and deposited with the Certificate Custodian, on behalf of The
Depository Trust Company, if directed to do so pursuant instructions from The
Depository Trust Company. Such Certificates shall initially be registered in the
Certificate Register in the name of the nominee of the initial Clearing Agency,
and no Beneficial Owner will receive a definitive certificate representing such
Beneficial Owner's interest in the Book-Entry Certificates, except as provided
in Section 5.07. Unless and until definitive, fully registered certificates
("Definitive Certificates") have been issued to Beneficial Owners pursuant to
Section 5.07:

               (i)the  provisions  of this Section  5.01(b)  shall be in
      full force and effect;

               (ii) the Seller, the Master Servicer, the Certificate Registrar
      and the Trust Administrator may deal with the Clearing Agency for all
      purposes (including the making of distributions on the Book-Entry
      Certificates and the taking of actions by the Holders of Book-Entry
      Certificates) as the authorized representative of the Beneficial Owners;

               (iii) to the extent that the provisions of this Section 5.01(b)
      conflict with any other provisions of this Agreement, the provisions of
      this Section 5.01(b) shall control;

               (iv) the rights of Beneficial Owners shall be exercised only
      through the Clearing Agency and shall be limited to those established by
      law, the rules, regulations and procedures of the Clearing Agency and
      agreements between such Beneficial Owners and the Clearing Agency and/or
      the Clearing Agency Participants, and all references in this Agreement to
      actions by Certificateholders shall, with respect to the Book-Entry
      Certificates, refer to actions taken by the Clearing Agency upon
      instructions from the Clearing Agency Participants, and all references in
      this Agreement to distributions, notices, reports and statements to
      Certificateholders shall, with respect to the Book-Entry Certificates,
      refer to distributions, notices, reports and statements to the Clearing
      Agency or its nominee, as registered holder of the Book-Entry
      Certificates, as the case may be, for distribution to Beneficial Owners in
      accordance with the procedures of the Clearing Agency; and

               (v)the initial Clearing Agency will make book-entry transfers
      among the Clearing Agency Participants and receive and transmit
      distributions of principal and interest on the Certificates to the
      Clearing Agency Participants, for distribution by such Clearing Agency
      Participants to the Beneficial Owners or their nominees.

            For purposes of any provision of this Agreement requiring or
permitting actions with the consent of, or at the direction of, Holders of
Book-Entry Certificates evidencing specified Voting Interests, such direction or
consent shall be given by Beneficial Owners having the requisite Voting
Interests, acting through the Clearing Agency.

            Unless and until Definitive Certificates have been issued to
Beneficial Owners pursuant to Section 5.07, copies of the reports or statements
referred to in Section 4.04 shall be available to Beneficial Owners upon written
request to the Trust Administrator at the Corporate Trust Office.

            SECTION 5.02      REGISTRATION OF CERTIFICATES.

            (a) The Trust Administrator shall cause to be kept at one of the
offices or agencies to be maintained in accordance with the provisions of
Section 5.06 a Certificate Register in which, subject to such reasonable
regulations as it may prescribe, the Trust Administrator shall provide for the
registration of Certificates and of transfers and exchanges of Certificates as
herein provided. The Trust Administrator shall act as, or shall appoint, a
Certificate Registrar for the purpose of registering Certificates and transfers
and exchanges of Certificates as herein provided.

            Upon surrender for registration of transfer of any Certificate at
any office or agency maintained for such purpose pursuant to Section 5.06 (and
subject to the provisions of this Section 5.02) the Trust Administrator shall
execute, and shall date, authenticate (or cause the Authenticating Agent to
authenticate) and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of a like aggregate principal portion
or Percentage Interest and of the same Class.

            At the option of the Certificateholders, Certificates may be
exchanged for other Certificates of authorized Denominations of a like aggregate
principal portion or Percentage Interest and of the same Class upon surrender of
the Certificates to be exchanged at any such office or agency. Whenever any
Certificates are so surrendered for exchange, the Trust Administrator shall
execute, and shall date, authenticate (or cause the Authenticating Agent to
authenticate) and deliver, the Certificates which the Certificateholder making
the exchange is entitled to receive. Every Certificate presented or surrendered
for transfer or exchange shall (if so required by the Certificate Registrar or
the Trust Administrator) be duly endorsed by, or be accompanied by a written
instrument of transfer in form satisfactory to the Certificate Registrar, duly
executed by the Holder thereof or his attorney duly authorized in writing.

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

            All Certificates surrendered for transfer and exchange shall be
canceled by the Certificate Registrar, the Trust Administrator or the
Authenticating Agent in accordance with their standard procedures.

            (b) No transfer of a Class I-B-4, Class I-B-5, Class I-B-6, Class
II-B-4, Class II-B-5 or Class II-B-6 Certificate shall be made unless the
registration requirements of the Securities Act of 1933, as amended, and any
applicable State securities laws are complied with, or such transfer is exempt
from the registration requirements under said Act and laws. In the event that a
transfer is to be made in reliance upon an exemption from said Act or laws, (i)
unless such transfer is made in reliance on Rule 144A, the Trust Administrator
or the Seller may, if such transfer is to be made within three years after the
later of (i) the date of the initial sale of Certificates or (ii) the last date
on which the Seller or any affiliate thereof was a Holder of the Certificates
proposed to be transferred, require a Class I-B-4, Class I-B-5, Class I-B-6,
Class II-B-4, Class II-B-5 or Class II-B-6 Certificateholder to deliver a
written Opinion of Counsel acceptable to and in form and substance satisfactory
to the Trust Administrator and the Seller, to the effect that such transfer may
be made pursuant to an exemption, describing the applicable exemption and the
basis therefor, from said Act and laws or is being made pursuant to said Act and
laws, which Opinion of Counsel shall not be an expense of the Trust
Administrator, the Trustee, the Seller or the Master Servicer, and (ii) the
Trustee shall require the transferee (other than an affiliate of the Seller on
the Closing Date) to execute an investment letter in the form of Exhibit J
hereto certifying to the Seller and the Trust Administrator the facts
surrounding such transfer, which investment letter shall not be an expense of
the Trust Administrator, the Trustee, the Seller or the Master Servicer. The
Holder of a Class I-B-4, Class I-B-5, Class I-B-6, Class II-B-4, Class II-B-5 or
Class II-B-6 Certificate desiring to effect such transfer shall, and does hereby
agree to, indemnify the Trust Administrator, the Trustee, the Seller, the Master
Servicer and any Paying Agent acting on behalf of the Trustee against any
liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws. Neither the Seller nor the Trust
Administrator is under an obligation to register the Class I-B-4, Class I-B-5,
Class I-B-6, Class II-B-4, Class II-B-5 or Class II-B-6 Certificates under said
Act or any other securities law.

            (c) No transfer of a Class B Certificate shall be made unless the
Trust Administrator shall have received (i) a representation letter from the
transferee in the form of Exhibit J hereto, in the case of a Class I-B-4, Class
I-B-5, Class I-B-6, Class II-B-4, Class II-B-5 or Class II-B-6 Certificate, or
in the form of Exhibit K hereto, in the case of a Class I-B-1, Class I-B-2,
Class I-B-3, Class II-B-1, Class II-B-2 or Class II-B-3 Certificate, to the
effect that either (a) such transferee is not an employee benefit plan or other
retirement arrangement subject to Title I of ERISA or Code Section 4975, or a
governmental plan, as defined in Section 3(32) of ERISA, subject to any federal,
state or local law ("Similar Law") which is to a material extent similar to the
foregoing provisions of ERISA or the Code (collectively, a "Plan") and is not a
person acting on behalf of or using the assets of any such Plan, which
representation letter shall not be an expense of the Trust Administrator, the
Trustee, the Seller or the Master Servicer or (b) if such transferee is an
insurance company, (A) the source of funds used to purchase the Class B
Certificate is an "insurance company general account" (as such term is defined
in Section V(e) of Prohibited Transaction Class Exemption 95-60 ("PTE 95-60"),
60 Fed. Reg. 35925 (July 12, 1995)), (B) there is no Plan with respect to which
the amount of such general account's reserves and liabilities for the
contract(s) held by or on behalf of such Plan and all other Plans maintained by
the same employer (or affiliate thereof as defined in Section V(a)(1) of PTE
95-60) or by the same employee organization exceeds 10% of the total of all
reserves and liabilities of such general account (as such amounts are determined
under Section I(a) of PTE 95-60) at the date of acquisition and (C) the purchase
and holding of such Class B Certificates are covered by Sections I and III of
PTE 95-60 or (ii) in the case of any such Class B Certificate presented for
registration in the name of a Plan, or a trustee of any such Plan, (A) an
Opinion of Counsel satisfactory to the Trust Administrator and the Seller to the
effect that the purchase or holding of such Class B Certificate will not result
in the assets of the Trust Estate being deemed to be "plan assets" and subject
to the prohibited transaction provisions of ERISA, the Code or Similar Law and
will not subject the Trust Administrator, the Trustee, the Seller or the Master
Servicer to any obligation in addition to those undertaken in this Agreement,
which Opinion of Counsel shall not be an expense of the Trust Administrator, the
Trustee, the Seller or the Master Servicer and (B) such other opinions of
counsel, officer's certificates and agreements as the Seller or the Master
Servicer may require in connection with such transfer, which opinions of
counsel, officers' certificates and agreements shall not be an expense of the
Trust Administrator, the Trustee, the Seller or the Master Servicer. The Class B
Certificates shall bear a legend referring to the foregoing restrictions
contained in this paragraph.

            (d) No legal or beneficial interest in all or any portion of the
Class I-A-R or Class I-A-LR Certificate may be transferred directly or
indirectly to a "disqualified organization" within the meaning of Code Section
860E(e)(5) or an agent of a disqualified organization (including a broker,
nominee, or middleman), to a Plan or a Person acting on behalf of or investing
the assets of a Plan (such Plan or Person, an "ERISA Prohibited Holder") or to
an individual, corporation, partnership or other person unless such transferee
(i) is not a Non-U.S. Person or (ii) is a Non-U.S. Person that holds the Class
I-A-R or Class I-A-LR Certificate in connection with the conduct of a trade or
business within the United States and has furnished the transferor and the Trust
Administrator with an effective Internal Revenue Service Form 4224 or (iii) is a
Non-U.S. Person that has delivered to both the transferor and the Trust
Administrator an opinion of a nationally recognized tax counsel to the effect
that the transfer of the Class I-A-R or Class I-A-LR Certificate to it is in
accordance with the requirements of the Code and the regulations promulgated
thereunder and that such transfer of the Class I-A-R or Class I-A-LR Certificate
will not be disregarded for federal income tax purposes (any such person who is
not covered by clauses (i), (ii) or (iii) above being referred to herein as a
"Non-permitted Foreign Holder"), and any such purported transfer shall be void
and have no effect. The Trust Administrator shall not execute, and shall not
authenticate (or cause the Authenticating Agent to authenticate) and deliver, a
new Class I-A-R or Class I-A-LR Certificate in connection with any such transfer
to a disqualified organization or agent thereof (including a broker, nominee or
middleman), an ERISA Prohibited Holder or a Non-permitted Foreign Holder, and
neither the Certificate Registrar nor the Trust Administrator shall accept a
surrender for transfer or registration of transfer, or register the transfer of,
the Class I-A-R or Class I-A-LR Certificate, unless the transferor shall have
provided to the Trust Administrator an affidavit, substantially in the form
attached as Exhibit H hereto, signed by the transferee, to the effect that the
transferee is not such a disqualified organization, an agent (including a
broker, nominee, or middleman) for any entity as to which the transferee has not
received a substantially similar affidavit, an ERISA Prohibited Holder or a
Non-permitted Foreign Holder, which affidavit shall contain the consent of the
transferee to any such amendments of this Agreement as may be required to
further effectuate the foregoing restrictions on transfer of the Class I-A-R or
Class I-A-LR Certificate to disqualified organizations, ERISA Prohibited Holders
or Non-permitted Foreign Holders. Such affidavit shall also contain the
statement of the transferee that (i) the transferee has historically paid its
debts as they have come due and intends to do so in the future, (ii) the
transferee understands that it may incur liabilities in excess of cash flows
generated by the residual interest, (iii) the transferee intends to pay taxes
associated with holding the residual interest as they become due and (iv) the
transferee will not transfer the Class I-A-R or Class I-A-LR Certificate to any
Person who does not provide an affidavit substantially in the form attached as
Exhibit H hereto.

            The affidavit described in the preceding paragraph, if not executed
in connection with the initial issuance of the Class I-A-R or Class I-A-LR
Certificate, shall be accompanied by a written statement in the form attached as
Exhibit I hereto, signed by the transferor, to the effect that as of the time of
the transfer, the transferor has no actual knowledge that the transferee is a
disqualified organization, ERISA Prohibited Holder or Non-permitted Foreign
Holder, and has no knowledge or reason to know that the statements made by the
transferee with respect to clauses (i) and (iii) of the last sentence of the
preceding paragraph are not true. The Class I-A-R and Class I-A-LR Certificates
shall bear a legend referring to the foregoing restrictions contained in this
paragraph and the preceding paragraph.

            Upon notice to the Master Servicer that any legal or beneficial
interest in any portion of the Class I-A-R or Class I-A-LR Certificate has been
transferred, directly or indirectly, to a disqualified organization or agent
thereof (including a broker, nominee, or middleman) in contravention of the
foregoing restrictions, (i) such transferee shall be deemed to hold the Class
I-A-R or Class I-A-LR Certificate in constructive trust for the last transferor
who was not a disqualified organization or agent thereof, and such transferor
shall be restored as such owner of such Class I-A-R or Class I-A-LR Certificate
as completely as if such transfer had never occurred, provided that the Master
Servicer may, but is not required to, recover any distributions made to such
transferee with respect to the Class I-A-R or Class I-A-LR Certificate, and (ii)
the Master Servicer agrees to furnish to the Internal Revenue Service and to any
transferor of the Class I-A-R or Class I-A-LR Certificate or such agent (within
60 days of the request therefor by the transferor or agent) such information
necessary to the application of Code Section 860E(e) as may be required by the
Code, including but not limited to the present value of the total anticipated
excess inclusions with respect to the Class I-A-R or Class I-A-LR Certificate
(or portion thereof) for periods after such transfer. At the election of the
Master Servicer, the cost to the Master Servicer of computing and furnishing
such information may be charged to the transferor or such agent referred to
above; however, the Master Servicer shall in no event be excused from furnishing
such information.

            SECTION 5.03 MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.

            If (i) any mutilated Certificate is surrendered to the Trust
Administrator or the Authenticating Agent, or the Trust Administrator or the
Authenticating Agent receives evidence to its satisfaction of the destruction,
loss or theft of any Certificate, and (ii) there is delivered to the Trust
Administrator or the Authenticating Agent such security or indemnity as may be
required by them to hold each of them harmless, then, in the absence of notice
to the Trust Administrator or the Authenticating Agent that such Certificate has
been acquired by a bona fide purchaser, the Trust Administrator shall execute
and authenticate (or cause the Authenticating Agent to authenticate) and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Certificate, a new Certificate of like tenor and principal portion or
Percentage Interest and of the same Class. Upon the issuance of any new
Certificate under this Section, the Trust Administrator or the Certificate
Registrar may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expense (including the fees and expenses of the Trust Administrator or the
Authenticating Agent) in connection therewith. Any duplicate Certificate issued
pursuant to this Section shall constitute complete and indefeasible evidence of
ownership in the Trust Estate, as if originally issued, whether or not the lost,
stolen, or destroyed Certificate shall be found at any time.

            SECTION 5.04 PERSONS DEEMED OWNERS.

            Prior to the due presentation of a Certificate for registration of
transfer, the Seller, the Master Servicer, the Trustee, the Trust Administrator,
the Certificate Registrar and any agent of the Seller, the Master Servicer, the
Trustee, the Trust Administrator or the Certificate Registrar may treat the
Person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions pursuant to Section 4.01,
and for all other purposes whatsoever, and neither the Seller, the Master
Servicer, the Trustee, the Trust Administrator, the Certificate Registrar nor
any agent of the Seller, the Master Servicer, the Trustee, the Trust
Administrator or the Certificate Registrar shall be affected by notice to the
contrary.

            SECTION 5.05 ACCESS TO LIST OF CERTIFICATEHOLDERS' NAMES AND
ADDRESSES.

            (a) If the Trust Administrator is not acting as Certificate
Registrar, the Certificate Registrar shall furnish or cause to be furnished to
the Trust Administrator, within 15 days after receipt by the Certificate
Registrar of a request by the Trust Administrator in writing, a list, in such
form as the Trust Administrator may reasonably require, of the names and
addresses of the Certificateholders of each Class as of the most recent Record
Date.

            (b) If five or more Certificateholders (hereinafter referred to as
"applicants") apply in writing to the Trust Administrator, and such application
states that the applicants desire to communicate with other Certificateholders
with respect to their rights under this Agreement or under the Certificates and
is accompanied by a copy of the communication which such applicants propose to
transmit, then the Trust Administrator shall, within five Business Days
following the receipt of such application, afford such applicants access during
normal business hours to the most recent list of Certificateholders held by the
Trust Administrator. If such a list is as of the date more than 90 days prior to
the date of receipt of such applicants' request and the Trust Administrator is
not the Certificate Registrar, the Trust Administrator shall promptly request
from the Certificate Registrar a current list as provided in paragraph (a)
hereof, and shall afford such applicants access to such list promptly upon
receipt.

            (c) Every Certificateholder, by receiving and holding a Certificate,
agrees with the Seller, the Master Servicer, the Certificate Registrar, the
Trust Administrator and the Trustee that neither the Seller, the Master
Servicer, the Certificate Registrar, the Trust Administrator nor the Trustee
shall be held accountable by reason of the disclosure of any such information as
to the names, addresses and Percentage Interests of the Certificateholders
hereunder, regardless of the source from which such information was delivered.

            SECTION 5.06 MAINTENANCE OF OFFICE OR AGENCY.

            The Trust Administrator will maintain, at its expense, an office or
agency where Certificates may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Certificate Registrar in
respect of the Certificates and this Agreement may be served. The Trust
Administrator initially designates the Corporate Trust Office and the principal
corporate trust office of the Authenticating Agent, if any, as its offices and
agencies for said purposes.

            SECTION 5.07 DEFINITIVE CERTIFICATES.

            If (i)(A) the Master Servicer advises the Trust Administrator in
writing that the Clearing Agency is no longer willing or able properly to
discharge its responsibilities as depository with respect to the Book-Entry
Certificates, and (B) the Master Servicer is unable to locate a qualified
successor, (ii) the Master Servicer, at its option, advises the Trust
Administrator in writing that it elects to terminate the book-entry system
through the Clearing Agency or (iii) after the occurrence of dismissal or
resignation of the Master Servicer, Beneficial Owners representing aggregate
Voting Interests of not less than 51% of the aggregate Voting Interests of each
outstanding Class of Book-Entry Certificates advise the Trust Administrator
through the Clearing Agency and Clearing Agency Participants in writing that the
continuation of a book-entry system through the Clearing Agency is no longer in
the best interests of the Beneficial Owners, or (iv) upon the occurrence of the
events specified in Section 4.07(g), the Trust Administrator shall notify the
Beneficial Owners, through the Clearing Agency, of the occurrence of any such
event and of the availability of Definitive Certificates to Beneficial Owners
requesting the same. Upon surrender to the Trust Administrator by the Clearing
Agency of the Certificates held of record by its nominee, accompanied by
reregistration instructions and directions to execute and authenticate new
Certificates from the Master Servicer, the Trust Administrator shall execute and
authenticate Definitive Certificates for delivery at its Corporate Trust Office.
The Master Servicer shall arrange for, and will bear all costs of, the printing
and issuance of such Definitive Certificates. Neither the Seller, the Master
Servicer, the Trustee nor the Trust Administrator shall be liable for any delay
in delivery of such instructions by the Clearing Agency and may conclusively
rely on, and shall be protected in relying on, such instructions.

            SECTION 5.08 NOTICES TO CLEARING AGENCY.

            Whenever notice or other communication to the Holders of Book-Entry
Certificates is required under this Agreement, unless and until Definitive
Certificates shall have been issued to Beneficial Owners pursuant to Section
5.07, the Trust Administrator shall give all such notices and communications
specified herein to be given to Holders of Book-Entry Certificates to the
Clearing Agency.

                                   ARTICLE VI

                       THE SELLER AND THE MASTER SERVICER

            SECTION 6.01 LIABILITY OF THE SELLER AND THE MASTER SERVICER.

            The Seller and the Master Servicer shall each be liable in
accordance herewith only to the extent of the obligations specifically imposed
by this Agreement and undertaken hereunder by the Seller and the Master
Servicer.

            SECTION 6.02 MERGER OR CONSOLIDATION OF THE SELLER OR THE MASTER
SERVICER.

            Subject to the following paragraph, the Seller and the Master
Servicer each will keep in full effect its existence, rights and franchises as a
corporation under the laws of the jurisdiction of its incorporation, and will
obtain and preserve its qualification to do business as a foreign corporation in
each jurisdiction in which such qualification is or shall be necessary to
protect the validity and enforceability of this Agreement, the Certificates or
any of the Mortgage Loans and to perform its respective duties under this
Agreement.

            The Seller or the Master Servicer may be merged or consolidated with
or into any Person, or transfer all or substantially all of its assets to any
Person, in which case any Person resulting from any merger or consolidation to
which the Seller or Master Servicer shall be a party, or any Person succeeding
to the business of the Seller or Master Servicer, shall be the successor of the
Seller or Master Servicer hereunder, without the execution or filing of any
paper or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding; provided, however, that, in the case of
the Master Servicer, any such successor or resulting Person shall be qualified
to service mortgage loans for FNMA or FHLMC.

            SECTION 6.03 LIMITATION ON LIABILITY OF THE SELLER, THE MASTER
SERVICER AND OTHERS.

            Neither the Seller nor the Master Servicer nor any subcontractor nor
any of the partners, directors, officers, employees or agents of any of them
shall be under any liability to the Trust Estate or the Certificateholders and
all such Persons shall be held harmless for any action taken or for refraining
from the taking of any action in good faith pursuant to this Agreement, or for
errors in judgment; provided, however, that this provision shall not protect any
such Person against any breach of warranties or representations made herein or
against any liability which would otherwise be imposed by reason of willful
misfeasance, bad faith or gross negligence in the performance of duties or by
reason of reckless disregard of obligations and duties hereunder. The Seller,
the Master Servicer, any subcontractor, and any partner, director, officer,
employee or agent of any of them shall be entitled to indemnification by the
Trust Estate and will be held harmless against any loss, liability or expense
incurred in connection with any legal action relating to this Agreement or the
Certificates, including without limitation, any legal action against the Trustee
in its capacity as Trustee hereunder, other than any loss, liability or expense
(including without limitation, expenses payable by the Master Servicer under
8.06) incurred by reason of willful misfeasance, bad faith or gross negligence
in the performance of his or its duties hereunder or by reason of reckless
disregard of his or its obligations and duties hereunder. The Seller, the Master
Servicer and any of the directors, officers, employees or agents of either may
rely in good faith on any document of any kind which, prima facie, is properly
executed and submitted by any Person respecting any matters arising hereunder.
Neither the Seller nor the Master Servicer shall be under any obligation to
appear in, prosecute or defend any legal action unless such action is related to
its respective duties under this Agreement and which in its opinion does not
involve it in any expense or liability; provided, however, that the Seller or
the Master Servicer may in its discretion undertake any such action which it may
deem necessary or desirable with respect to this Agreement and the rights and
duties of the parties hereto and the interests of the Certificateholders
hereunder if the Certificateholders offer to the Seller or the Master Servicer,
as the case may be, reasonable security or indemnity against the costs, expenses
and liabilities which may be incurred therein or thereby. In such event, the
legal expenses and costs of such action and any liability resulting therefrom
shall be expenses, costs and liabilities of the Trust Estate, and the Seller or
the Master Servicer shall be entitled to be reimbursed therefor out of the
Certificate Account, and such amounts shall, on the following Distribution Date
or Distribution Dates, be allocated between Group I and Group II, pro rata, and
within each Group in reduction of distributions on the Class A Certificates and
Components and Class B Certificates in the same manner as Realized Losses are
allocated pursuant to Section 4.02(a).

            SECTION 6.04 RESIGNATION OF THE MASTER SERVICER.

            The Master Servicer shall not resign from the obligations and duties
hereby imposed on it except upon determination that its duties hereunder are no
longer permissible under applicable law or are in material conflict by reason of
applicable law with any other activities carried on by it. Any such
determination permitting the resignation of the Master Servicer shall be
evidenced by an Opinion of Counsel to such effect delivered to the Trustee and
the Trust Administrator, a copy of which shall be delivered, but not addressed,
to Ambac. No such resignation shall become effective until the Trustee, the
Trust Administrator or a successor servicer shall have assumed the Master
Servicer's responsibilities, duties, liabilities and obligations hereunder.

            SECTION 6.05 COMPENSATION TO THE MASTER SERVICER.

            The Master Servicer shall be entitled to receive a monthly fee equal
to the Master Servicing Fee, as compensation for services rendered by the Master
Servicer under this Agreement. The Master Servicer also will be entitled to any
late reporting fees paid by a Servicer pursuant to its Servicing Agreement, any
investment income on funds on deposit in the Certificate Account and any
Liquidation Profits to which a Servicer is not entitled under its Servicing
Agreement.

            SECTION 6.06 ASSIGNMENT OR DELEGATION OF DUTIES BY MASTER SERVICER.

            The Master Servicer shall not assign or transfer any of its rights,
benefits or privileges under this Agreement to any other Person, or delegate to
or subcontract with, or authorize or appoint any other Person to perform any of
the duties, covenants or obligations to be performed by the Master Servicer
without the prior written consent of the Trustee and the Trust Administrator,
and any agreement, instrument or act purporting to effect any such assignment,
transfer, delegation or appointment shall be void. Notwithstanding the
foregoing, the Master Servicer shall have the right without the prior written
consent of the Trustee or the Trust Administrator (i) to assign its rights and
delegate its duties and obligations hereunder; provided, however, that (a) the
purchaser or transferee accepting such assignment or delegation is qualified to
service mortgage loans for FNMA or FHLMC, is satisfactory to the Trustee and the
Trust Administrator, in the exercise of its reasonable judgment, and executes
and delivers to the Trustee and the Trust Administrator an agreement, in form
and substance reasonably satisfactory to the Trustee and the Trust
Administrator, which contains an assumption by such purchaser or transferee of
the due and punctual performance and observance of each covenant and condition
to be performed or observed by the Master Servicer hereunder from and after the
date of such agreement; and (b) each applicable Rating Agency's rating of any
Certificates in effect immediately prior to such assignment, sale or transfer is
not reasonably likely to be qualified, downgraded or withdrawn as a result of
such assignment, sale or transfer and the Certificates are not reasonably likely
to be placed on credit review status by any such Rating Agency (without, in the
case of the Class A-3 Certificates, giving effect to the guaranty provided by
Ambac); and (ii) to delegate to, subcontract with, authorize, or appoint an
affiliate of the Master Servicer to perform and carry out any duties, covenants
or obligations to be performed and carried out by the Master Servicer under this
Agreement and hereby agrees so to delegate, subcontract, authorize or appoint to
an affiliate of the Master Servicer any duties, covenants or obligations to be
performed and carried out by the Master Servicer to the extent that such duties,
covenants or obligations are to be performed in any state or states in which the
Master Servicer is not authorized to do business as a foreign corporation but in
which the affiliate is so authorized. In no case, however, shall any permitted
assignment and delegation relieve the Master Servicer of any liability to the
Trustee, the Trust Administrator or the Seller under this Agreement, incurred by
it prior to the time that the conditions contained in clause (i) above are met.

            SECTION 6.07 INDEMNIFICATION OF TRUSTEE, THE TRUST ADMINISTRATOR AND
SELLER BY MASTER SERVICER.

            The Master Servicer shall indemnify and hold harmless the Trustee,
the Trust Administrator and the Seller and any director, officer or agent
thereof against any loss, liability or expense, including reasonable attorney's
fees, arising out of, in connection with or incurred by reason of willful
misfeasance, bad faith or negligence in the performance of duties of the Master
Servicer under this Agreement or by reason of reckless disregard of its
obligations and duties under this Agreement. Any payment pursuant to this
Section made by the Master Servicer to the Trustee, the Trust Administrator or
the Seller shall be from such entity's own funds, without reimbursement
therefor. The provisions of this Section 6.07 shall survive the termination of
this Agreement.

                                   ARTICLE VII

                                     DEFAULT

            SECTION 7.01 EVENTS OF DEFAULT.

            In case one or more of the following Events of Default by the Master
Servicer shall occur and be continuing, that is to say:

               (i)any failure by the Master Servicer (a) to remit any funds to
      the Paying Agent as required by Section 4.03 or (b) to distribute or cause
      to be distributed to Certificateholders any payment required to be made by
      the Master Servicer under the terms of this Agreement which, in either
      case, continues unremedied for a period of three business days after the
      date upon which written notice of such failure, requiring the same to be
      remedied, shall have been given to the Master Servicer by the Trustee or
      to the Master Servicer and the Trustee by the holders of Certificates
      evidencing in the aggregate not less than 25% of the aggregate Voting
      Interest represented by all Certificates;

               (ii) any failure on the part of the Master Servicer duly to
      observe or perform in any material respect any other of the covenants or
      agreements on the part of the Master Servicer in the Certificates or in
      this Agreement which continues unremedied for a period of 60 days after
      the date on which written notice of such failure, requiring the same to be
      remedied, shall have been given to the Master Servicer by the Trustee, or
      to the Master Servicer and the Trustee by the holders of Certificates
      evidencing in the aggregate not less than 25% of the aggregate Voting
      Interest represented by all Certificates;

               (iii) a decree or order of a court or agency or supervisory
      authority having jurisdiction in the premises for the appointment of a
      trustee, conservator, receiver or liquidator in any bankruptcy,
      insolvency, readjustment of debt, marshaling of assets and liabilities or
      similar proceedings, or for the winding-up or liquidation of its affairs,
      shall have been entered against the Master Servicer and such decree or
      order shall have remained in force undischarged and unstayed for a period
      of 60 days;

               (iv) the Master Servicer shall consent to the appointment of a
      trustee, conservator, receiver or liquidator or liquidating committee in
      any bankruptcy, insolvency, readjustment of debt, marshaling of assets and
      liabilities, voluntary liquidation or similar proceedings of or relating
      to the Master Servicer, or of or relating to all or substantially all of
      its property;

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

               (vi) the Master Servicer shall be dissolved, or shall dispose of
      all or substantially all of its assets; or consolidate with or merge into
      another entity or shall permit another entity to consolidate or merge into
      it, such that the resulting entity does not meet the criteria for a
      successor servicer, as specified in Section 6.02 hereof; or

               (vii) the Master Servicer and any subservicer appointed by it
      becomes ineligible to service for both FNMA and FHLMC, which ineligibility
      continues unremedied for a period of 90 days.

then, and in each and every such case, subject to applicable law, so long as an
Event of Default shall not have been remedied, either the Trustee or the holders
of Certificates evidencing in the aggregate not less than 66 2/3% of the
aggregate Voting Interest represented by all Certificates, by notice in writing
to the Master Servicer and the Trust Administrator (and to the Trustee if given
by the Certificateholders) may terminate all of the rights and obligations of
the Master Servicer under this Agreement and in and to the Mortgage Loans, but
without prejudice to any rights which the Master Servicer may have to the
aggregate Master Servicing Fees due prior to the date of transfer of the Master
Servicer's responsibilities hereunder, reimbursement of expenses to the extent
permitted by this Agreement, Periodic Advances and other advances of its own
funds. Upon receipt by the Master Servicer of such written notice, all authority
and power of the Master Servicer under this Agreement, whether with respect to
the Certificates or the Mortgage Loans or otherwise, shall pass to and be vested
in the Trust Administrator, on behalf of the Trustee pursuant to and under this
Section, subject to the provisions of Section 7.05; and, without limitation, the
Trust Administrator, on behalf of the Trustee is hereby authorized and empowered
to execute and deliver, on behalf of the Master Servicer, as attorney-in-fact or
otherwise, any and all documents and other instruments, and to do or accomplish
all other acts or things necessary or appropriate to effect the purposes of such
notice of termination, whether to complete the transfer and endorsement or
assignment of the Mortgage Loans and related documents or otherwise. The Master
Servicer agrees to cooperate with the Trust Administrator and Trustee in
effecting the termination of the Master Servicer's responsibilities and rights
hereunder and shall promptly provide the Trustee all documents and records
reasonably requested by it to enable it to assume the Master Servicer's
functions hereunder and shall promptly also transfer to the Trust Administrator,
on behalf of the Trustee all amounts which then have been or should have been
deposited in the Certificate Account by the Master Servicer or which are
thereafter received by the Master Servicer with respect to the Mortgage Loans.

            SECTION 7.02 OTHER REMEDIES OF TRUSTEE.

            During the continuance of any Event of Default, so long as such
Event of Default shall not have been remedied, the Trustee, in addition to the
rights specified in Section 7.01, shall have the right, in its own name as
trustee of an express trust, to take all actions now or hereafter existing at
law, in equity or by statute to enforce its rights and remedies and to protect
the interests, and enforce the rights and remedies, of the Certificateholders
(including the institution and prosecution of all judicial, administrative and
other proceedings and the filing of proofs of claim and debt in connection
therewith). Except as otherwise expressly provided in this Agreement, no remedy
provided for by this Agreement shall be exclusive of any other remedy, and each
and every remedy shall be cumulative and in addition to any other remedy and no
delay or omission to exercise any right or remedy shall impair any such right or
remedy or shall be deemed to be a waiver of any Event of Default.

            SECTION 7.03 DIRECTIONS BY CERTIFICATEHOLDERS AND DUTIES OF TRUSTEE
DURING EVENT OF DEFAULT.

            During the continuance of any Event of Default, Holders of
Certificates evidencing in the aggregate not less than 25% of the aggregate
Voting Interest represented by all Certificates may direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred upon the Trustee, under this Agreement;
provided, however, that the Trustee shall be under no obligation to pursue any
such remedy, or to exercise any of the rights or powers vested in it by this
agreement (including, without limitation, (i) the conducting or defending of any
administrative action or litigation hereunder or in relation hereto and (ii) the
terminating of the Master Servicer from its rights and duties as servicer
hereunder) at the request, order or direction of any of the Certificateholders,
unless such Certificateholders shall have offered to the Trustee reasonable
security or indemnity against the cost, expenses and liabilities which may be
incurred therein or thereby and, provided further, that, subject to the
provisions of Section 8.01, the Trustee shall have the right to decline to
follow any such direction if the Trustee, in accordance with an Opinion of
Counsel, determines that the action or proceeding so directed may not lawfully
be taken or if the Trustee in good faith determines that the action or
proceeding so directed would involve it in personal liability or be unjustly
prejudicial to the nonassenting Certificateholders.

            SECTION 7.04 ACTION UPON CERTAIN FAILURES OF THE MASTER SERVICER AND
UPON EVENT OF DEFAULT.

            In the event that the Trustee or the Trust Administrator shall have
knowledge of any failure of the Master Servicer specified in Section 7.01(i) or
(ii) which would become an Event of Default upon the Master Servicer's failure
to remedy the same after notice, the Trustee or the Trust Administrator may, but
need not if the Trustee or the Trust Administrator, as the case may be, deems it
not in the Certificateholders' best interest, give notice thereof to the Master
Servicer. For all purposes of this Agreement, in the absence of actual knowledge
by a corporate trust officer of the Trustee or the Trust Administrator, the
Trustee or the Trust Administrator, as the case may be, shall not be deemed to
have knowledge of any failure of the Master Servicer as specified in Section
7.01(i) and (ii) or any Event of Default unless notified thereof in writing by
the Master Servicer or by a Certificateholder.

            SECTION 7.05 TRUST ADMINISTRATOR TO ACT; APPOINTMENT OF SUCCESSOR.

            When the Master Servicer receives notice of termination pursuant to
Section 7.01 or the Trustee or the Trust Administrator receives the resignation
of the Master Servicer evidenced by an Opinion of Counsel pursuant to Section
6.04, the Trust Administrator, on behalf of the Trustee shall be the successor
in all respects to the Master Servicer in its capacity as master servicer under
this Agreement and the transactions set forth or provided for herein and shall
have the rights and powers and be subject to all the responsibilities, duties
and liabilities relating thereto placed on the Master Servicer by the terms and
provisions hereof and in its capacity as such successor shall have the same
limitation of liability herein granted to the Master Servicer. In the event that
the Trust Administrator is succeeding to the Master Servicer as the Master
Servicer, as compensation therefor, the Trust Administrator shall be entitled to
receive monthly such portion of the Master Servicing Fee, together with such
other servicing compensation as is agreed to at such time by the Trust
Administrator and the Master Servicer, but in no event more than 25% thereof
until the date of final cessation of the Master Servicer's servicing activities
hereunder. Notwithstanding the above, the Trust Administrator may, if it shall
be unwilling to so act, or shall, if it is unable to so act or to obtain a
qualifying bid as described below, appoint, or petition a court of competent
jurisdiction to appoint, any housing and home finance institution, bank or
mortgage servicing institution having a net worth of not less than $10,000,000
and meeting such other standards for a successor servicer as are set forth
herein, as the successor to the Master Servicer hereunder in the assumption of
all or any part of the responsibilities, duties or liabilities of the Master
Servicer hereunder; provided, however, that until such a successor master
servicer is appointed and has assumed the responsibilities, duties and
liabilities of the Master Servicer hereunder, the Trust Administrator shall
continue as the successor to the Master Servicer as provided above. The
compensation of any successor master servicer so appointed shall not exceed the
compensation specified in Section 6.05 hereof. In the event the Trust
Administrator is required to solicit bids as provided above, the Trust
Administrator shall solicit, by public announcement, bids from housing and home
finance institutions, banks and mortgage servicing institutions meeting the
qualifications set forth in the preceding sentence for the purchase of the
master servicing functions. Such public announcement shall specify that the
successor master servicer shall be entitled to the full amount of the Master
Servicing Fee as compensation together with the other servicing compensation in
the form of late reporting fees or otherwise as provided in Section 6.05. Within
30 days after any such public announcement, the Trust Administrator shall
negotiate and effect the sale, transfer and assignment of the master servicing
rights and responsibilities hereunder to the qualified party submitting the
highest qualifying bid. The Trust Administrator shall deduct all costs and
expenses of any public announcement and of any sale, transfer and assignment of
the servicing rights and responsibilities hereunder from any sum received by the
Trust Administrator from the successor to the Master Servicer in respect of such
sale, transfer and assignment. After such deductions, the remainder of such sum
shall be paid by the Trust Administrator to the Master Servicer at the time of
such sale, transfer and assignment to the Master Servicer's successor. The Trust
Administrator and such successor shall take such action, consistent with this
Agreement, as shall be necessary to effectuate any such succession. The Master
Servicer agrees to cooperate with the Trust Administrator and any successor
servicer in effecting the termination of the Master Servicer's servicing
responsibilities and rights hereunder and shall promptly provide the Trust
Administrator or such successor master servicer, as applicable, all documents
and records reasonably requested by it to enable it to assume the Master
Servicer's function hereunder and shall promptly also transfer to the Trust
Administrator or such successor master servicer, as applicable, all amounts
which then have been or should have been deposited in the Certificate Account by
the Master Servicer or which are thereafter received by the Master Servicer with
respect to the Mortgage Loans. Neither the Trust Administrator nor any other
successor master servicer shall be deemed to be in default hereunder by reason
of any failure to make, or any delay in making, any distribution hereunder or
any portion thereof caused by (i) the failure of the Master Servicer to deliver,
or any delay in delivering, cash, documents or records to it, or (ii)
restrictions imposed by any regulatory authority having jurisdiction over the
Master Servicer. Notwithstanding anything to the contrary contained in Section
7.01 above or this Section 7.05, the Master Servicer shall retain all of its
rights and responsibilities hereunder, and no successor (including the Trust
Administrator) shall succeed thereto, if the assumption thereof by such
successor would cause the rating assigned to any Certificates to be revoked,
downgraded or placed on credit review status (other than for possible upgrading)
(without, in the case of the Class A-3 Certificates, giving effect to the
guaranty provided by Ambac) by either Rating Agency and the retention thereof by
the Master Servicer would avert such revocation, downgrading or review.

            SECTION 7.06 NOTIFICATION TO CERTIFICATEHOLDERS.

            Upon any termination of the Master Servicer or appointment of a
successor master servicer, in each case as provided herein, the Trust
Administrator shall give prompt written notice thereof to Certificateholders at
their respective addresses appearing in the Certificate Register. The Trust
Administrator shall also, within 45 days after the occurrence of any Event of
Default known to the Trust Administrator, give written notice thereof to
Certificateholders at their respective addresses appearing in the Certificate
Register, unless such Event of Default shall have been cured or waived within
said 45 day period.

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

            SECTION 8.01 DUTIES OF TRUSTEE AND THE TRUST ADMINISTRATOR.

            The Trustee and the Trust Administrator, prior to the occurrence of
an Event of Default and after the curing of all Events of Default which may have
occurred, undertakes to perform such duties and only such duties as are
specifically set forth in this Agreement. In case an Event of Default has
occurred (which has not been cured), the Trustee and the Trust Administrator,
subject to the provisions of Sections 7.01, 7.03, 7.04 and 7.05, shall exercise
such of the rights and powers vested in it by this Agreement, and use the same
degree of care and skill in its exercise as a prudent investor would exercise or
use under the circumstances in the conduct of such investor's own affairs.

            The Trustee and the Trust Administrator, upon receipt of all
resolutions, certificates, statements, opinions, reports, documents, orders or
other instruments furnished to the Trustee and the Trust Administrator which are
specifically required to be furnished pursuant to any provision of this
Agreement, shall examine them to determine whether they are in the form required
by this Agreement; provided, however, that the Trustee and the Trust
Administrator shall not be responsible for the accuracy or content of any
certificate, statement, instrument, report, notice or other document furnished
by the Master Servicer or the Servicers pursuant to Articles III, IV and IX.

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

               (i)Prior to the occurrence of an Event of Default and after the
      curing of all such Events of Default which may have occurred, the duties
      and obligations of the Trustee and the Trust Administrator shall be
      determined solely by the express provisions of this Agreement, the Trustee
      and the Trust Administrator shall not be liable except for the performance
      of such duties and obligations as are specifically set forth in this
      Agreement, no implied covenants or obligations shall be read into this
      Agreement against the Trustee and the Trust Administrator and, in the
      absence of bad faith on the part of the Trustee and the Trust
      Administrator, the Trustee and the Trust Administrator may conclusively
      rely, as to the truth of the statements and the correctness of the
      opinions expressed therein, upon any certificates or opinions furnished to
      the Trustee and the Trust Administrator, and conforming to the
      requirements of this Agreement;

               (ii) The Trustee and the Trust Administrator shall not be
      personally liable with respect to any action taken, suffered or omitted to
      be taken by it in good faith in accordance with the direction of holders
      of Certificates which evidence in the aggregate not less than 25% of the
      Voting Interest represented by all Certificates relating to the time,
      method and place of conducting any proceeding for any remedy available to
      the Trustee and the Trust Administrator, or exercising any trust or power
      conferred upon the Trustee and the Trust Administrator under this
      Agreement; and

               (iii) The Trustee and the Trust Administrator shall not be liable
      for any error of judgment made in good faith by any of their respective
      Responsible Officers, unless it shall be proved that the Trustee or the
      Trust Administrator or such Responsible Officer, as the case may be, was
      negligent in ascertaining the pertinent facts.

            None of the provisions contained in this Agreement shall require the
Trustee or the Trust Administrator to expend or risk its own funds or otherwise
incur personal financial liability in the performance of any of its duties
hereunder or in the exercise of any of its rights or powers if there is
reasonable ground for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

            SECTION 8.02 CERTAIN MATTERS AFFECTING THE TRUSTEE AND THE TRUST
ADMINISTRATOR.

            Except as otherwise provided in Section 8.01:

               (i)Each of the Trustee and the Trust Administrator may request
      and rely and shall be protected in acting or refraining from acting upon
      any resolution, Officers' Certificate, certificate of auditors or any
      other certificate, statement, instrument, opinion, report, notice,
      request, consent, order, appraisal, bond or other paper or document
      believed by it to be genuine and to have been signed or presented by the
      proper party or parties and the manner of obtaining consents and
      evidencing the authorization of the execution thereof shall be subject to
      such reasonable regulations as the Trustee or Trust Administrator, as
      applicable may prescribe;

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

               (iii) Neither of the Trustee nor the Trust Administrator shall be
      personally liable for any action taken, suffered or omitted by it in good
      faith and believed by it to be authorized or within the discretion or
      rights or powers conferred upon it by this Agreement;

               (iv) Subject to Section 7.04, the Trust Administrator shall not
      be accountable, shall have no liability and makes no representation as to
      any acts or omissions hereunder of the Master Servicer until such time as
      the Trust Administrator may be required to act as Master Servicer pursuant
      to Section 7.05 and thereupon only for the acts or omissions of the Trust
      Administrator as successor Master Servicer; and

               (v)Each of the Trustee and the Trust Administrator may execute
      any of the trusts or powers hereunder or perform any duties hereunder
      either directly or by or through agents or attorneys.

            SECTION 8.03 NEITHER TRUSTEE NOR TRUST ADMINISTRATOR REQUIRED TO
MAKE INVESTIGATION.

            Prior to the occurrence of an Event of Default hereunder and after
the curing of all Events of Default which may have occurred, neither the Trustee
nor the Trust Administrator shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, appraisal, bond,
Mortgage, Mortgage Note or other paper or document (provided the same appears
regular on its face), unless requested in writing to do so by holders of
Certificates evidencing in the aggregate not less than 51% of the Voting
Interest represented by all Certificates; provided, however, that if the payment
within a reasonable time to the Trustee or the Trust Administrator of the costs,
expenses or liabilities likely to be incurred by it in the making of such
investigation is, in the opinion of the Trustee or the Trust Administrator, not
reasonably assured to the Trustee or the Trust Administrator by the security
afforded to it by the terms of this Agreement, the Trustee or the Trust
Administrator may require reasonable indemnity against such expense or liability
as a condition to so proceeding. The reasonable expense of every such
investigation shall be paid by the Master Servicer or, if paid by the Trustee or
the Trust Administrator, shall be repaid by the Master Servicer upon demand.

            SECTION 8.04 NEITHER TRUSTEE NOR TRUST ADMINISTRATOR LIABLE FOR
CERTIFICATES OR MORTGAGE LOANS.

            The recitals contained herein and in the Certificates (other than
the certificate of authentication on the Certificates) shall be taken as the
statements of the Seller, and neither the Trustee nor the Trust Administrator
assumes responsibility as to the correctness of the same. Neither the Trustee
nor the Trust Administrator makes any representation for the correctness of the
same. Neither the Trustee nor the Trust Administrator makes any representation
as to the validity or sufficiency of this Agreement or of the Certificates or of
any Mortgage Loan or related document. Subject to Section 2.04, neither the
Trustee nor the Trust Administrator shall not be accountable for the use or
application by the Seller of any of the Certificates or of the proceeds of such
Certificates, or for the use or application of any funds paid to the Master
Servicer in respect of the Mortgage Loans deposited into the Certificate Account
by the Master Servicer or, in its capacity as trustee, for investment of any
such amounts.

            SECTION 8.05 TRUSTEE AND THE TRUST ADMINISTRATOR MAY OWN
CERTIFICATES.

            Each of the Trustee, the Trust Administrator and any agent thereof,
in its individual or any other capacity, may become the owner or pledgee of
Certificates with the same rights it would have if it were not Trustee, Trust
Administrator or such agent and may transact banking and/or trust business with
the Seller, the Master Servicer or their Affiliates.

            SECTION 8.06 THE MASTER SERVICER TO PAY FEES AND EXPENSES.

            The Master Servicer covenants and agrees to pay to each of the
Trustee and the Trust Administrator from time to time, and each of the Trustee
and the Trust Administrator shall be entitled to receive, reasonable
compensation (which shall not be limited by any provision of law in regard to
the compensation of a trustee of an express trust) for all services rendered by
it in the execution of the trusts hereby created and in the exercise and
performance of any of the powers and duties hereunder of the Trustee or the
Trust Administrator, as the case may be and the Master Servicer will pay or
reimburse the Trustee or the Trust Administrator, as the case may be upon its
request for all reasonable expenses, disbursements and advances incurred or made
by it in accordance with any of the provisions of this Agreement (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all persons not regularly in its employ) except any such expense, disbursement,
or advance as may arise from its negligence or bad faith.

            SECTION 8.07 ELIGIBILITY REQUIREMENTS.

            Each of the Trustee and the Trust Administrator hereunder shall at
all times (i) be a corporation or association having its principal office in a
state and city acceptable to the Seller, organized and doing business under the
laws of such state or the United States of America, authorized under such laws
to exercise corporate trust powers, having a combined capital and surplus of at
least $50,000,000, or shall be a member of a bank holding system, the aggregate
combined capital and surplus of which is at least $50,000,000, provided that its
separate capital and surplus shall at all times be at least the amount specified
in Section 310(a)(2) of the Trust Indenture Act of 1939, (ii) be subject to
supervision or examination by federal or state authority and (iii) have a credit
rating or be otherwise acceptable to the Rating Agencies such that neither of
the Rating Agencies would reduce their respective then current ratings of the
Certificates (or have provided such security from time to time as is sufficient
to avoid such reduction) as evidenced in writing by each Rating Agency. If such
corporation or association publishes reports of condition at least annually,
pursuant to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section the combined capital and
surplus of such corporation or association shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. In case at any time the Trustee or the Trust Administrator shall
cease to be eligible in accordance with the provisions of this Section, such
entity shall resign immediately in the manner and with the effect specified in
Section 8.08.

            SECTION 8.08 RESIGNATION AND REMOVAL.

            Either of the Trustee or the Trust Administrator may at any time
resign and be discharged from the trust hereby created by giving written notice
of resignation to the Master Servicer, such resignation to be effective upon the
appointment of a successor trustee or trust administrator. Upon receiving such
notice of resignation, the Master Servicer shall promptly appoint a successor
trustee or trust administrator by written instrument, in duplicate, one copy of
which instrument shall be delivered to the resigning entity and one copy to its
successor. If no successor trustee or trust administrator shall have been
appointed and have accepted appointment within 30 days after the giving of such
notice of resignation, the resigning Trustee or Trust Administrator, as the case
may be ,may petition any court of competent jurisdiction for the appointment of
a successor trustee or trust administrator.

            If at any time the Trustee or the Trust Administrator shall cease to
be eligible in accordance with the provisions of Section 8.07 and shall fail to
resign after written request for its resignation by the Master Servicer, or if
at any time the Trustee or the Trust Administrator shall become incapable of
acting, or an order for relief shall have been entered in any bankruptcy or
insolvency proceeding with respect to such entity, or a receiver of such entity
or of its property shall be appointed, or any public officer shall take charge
or control of the Trustee or the Trust Administrator or of the property or
affairs of the Trustee or the Trust Administrator for the purpose of
rehabilitation, conversion or liquidation, or the Master Servicer shall deem it
necessary in order to change the situs of the Trust Estate for state tax
reasons, then the Master Servicer shall remove the Trustee and/or the Trust
Administrator, as the case may be, and appoint a successor trustee and/or
successor trust administrator by written instrument, in duplicate, one copy of
which instrument shall be delivered to the Trustee or the Trust Administrator so
removed and one copy to the successor trustee or successor trust administrator,
as the case may be.

            The Holders of Certificates evidencing in the aggregate not less
than 51% of the Voting Interests represented by all Certificates (except that
any Certificate registered in the name of the Seller, the Master Servicer or any
affiliate thereof will not be taken into account in determining whether the
requisite Voting Interests has been obtained) may at any time remove the Trustee
and/or the Trust Administrator and appoint a successor by written instrument or
instruments, in triplicate, signed by such holders or their attorneys-in-fact
duly authorized, one complete set of which instruments shall be delivered to the
Master Servicer, one complete set of which shall be delivered to the entity or
entities so removed and one complete set of which shall be delivered to the
successor so appointed.

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

            SECTION 8.09      SUCCESSOR.

            Any successor trustee or successor trust administrator appointed as
provided in Section 8.08 shall execute, acknowledge and deliver to the Master
Servicer and to its predecessor trustee or trust administrator, as the case may
be an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the predecessor trustee or trust administrator shall
become effective, and such successor, without any further act, deed or
reconveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with like effect as if originally
named as trustee or trust administrator, as the case may be herein. The
predecessor trustee or trust administrator shall deliver to its successor all
Owner Mortgage Loan Files and related documents and statements held by it
hereunder (other than any Owner Mortgage Loan Files at the time held by a
Custodian, which Custodian shall become the agent of any successor trustee
hereunder), and the Seller, the Master Servicer and the predecessor entity shall
execute and deliver such instruments and do such other things as may reasonably
be required for more fully and certainly vesting and confirming in the successor
trustee or successor trust administrator, as the case may be all such rights,
powers, duties and obligations. No successor shall accept appointment as
provided in this Section unless at the time of such acceptance such successor
shall be eligible under the provisions of Section 8.07

            Upon acceptance of appointment by a successor as provided in this
Section, the Master Servicer shall mail notice of the succession of such trustee
or trust administrator hereunder to all Holders of Certificates at their
addresses as shown in the Certificate Register. If the Master Servicer fails to
mail such notice within ten days after acceptance of the successor trustee or
successor trust administrator, as the case may be, the successor trustee or
trust administrator shall cause such notice to be mailed at the expense of the
Master Servicer.

            SECTION 8.10 MERGER OR CONSOLIDATION.

            Any Person into which either the Trustee or the Trust Administrator
may be merged or converted or with which it may be consolidated, to which it may
sell or transfer its corporate trust business and assets as a whole or
substantially as a whole or any Person resulting from any merger, sale,
transfer, conversion or consolidation to which the Trustee or the Trust
Administrator shall be a party, or any Person succeeding to the business of such
entity, shall be the successor of the Trustee or Trust Administrator, as the
case may be, hereunder; provided, however, that (i) such Person shall be
eligible under the provisions of Section 8.07, without the execution or filing
of any paper or any further act on the part of any of the parties hereto,
anything herein to the contrary notwithstanding, and (ii) the Trustee or the
Trust Administrator, as the case may be, shall deliver an Opinion of Counsel to
the Seller and the Master Servicer to the effect that such merger,
consolidation, sale or transfer will not subject either the Upper-Tier REMIC or
the Lower-Tier REMIC to federal, state or local tax or cause either the
Upper-Tier REMIC or the Lower-Tier REMIC to fail to qualify as a REMIC, which
Opinion of Counsel shall be at the sole expense of the Trustee or the Trust
Administrator, as the case may be.

            SECTION 8.11      AUTHENTICATING AGENT.

            The Trust Administrator may appoint an Authenticating Agent, which
shall be authorized to act on behalf of the Trust Administrator in
authenticating Certificates. Wherever reference is made in this Agreement to the
authentication of Certificates by the Trust Administrator or the Trust
Administrator's countersignature, such reference shall be deemed to include
authentication on behalf of the Trust Administrator by the Authenticating Agent
and a certificate of authentication executed on behalf of the Trust
Administrator by the Authenticating Agent. The Authenticating Agent must be
acceptable to the Seller and the Master Servicer and must be a corporation
organized and doing business under the laws of the United States of America or
of any state, having a principal office and place of business in a state and
city acceptable to the Seller and the Master Servicer, having a combined capital
and surplus of at least $15,000,000, authorized under such laws to do a trust
business and subject to supervision or examination by federal or state
authorities.

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

            The Authenticating Agent may at any time resign by giving at least
30 days' advance written notice of resignation to the Trustee, the Trust
Administrator the Seller and the Master Servicer. The Trust Administrator may at
any time terminate the agency of the Authenticating Agent by giving written
notice thereof to the Authenticating Agent, the Seller and the Master Servicer.
Upon receiving a notice of resignation or upon such a termination, or in case at
any time the Authenticating Agent shall cease to be eligible in accordance with
the provisions of this Section 8.11, the Trust Administrator promptly shall
appoint a successor Authenticating Agent, which shall be acceptable to the
Master Servicer, and shall give written notice of such appointment to the
Seller, and shall mail notice of such appointment to all Certificateholders. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers, duties and responsibilities of
its predecessor hereunder, with like effect as if originally named as
Authenticating Agent herein. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section 8.11.

            The Authenticating Agent shall have no responsibility or liability
for any action taken by it as such at the direction of the Trust Administrator.
Any reasonable compensation paid to the Authenticating Agent shall be a
reimbursable expense under Section 8.06.

            SECTION 8.12 SEPARATE TRUSTEES AND CO-TRUSTEES.

            The Trustee shall have the power from time to time to appoint one or
more persons or corporations to act either as co-trustees jointly with the
Trustee, or as separate trustees, for the purpose of holding title to,
foreclosing or otherwise taking action with respect to any Mortgage Loan outside
the state where the Trustee has its principal place of business, where such
separate trustee or co-trustee is necessary or advisable (or the Trustee is
advised by the Master Servicer that such separate trustee or co-trustee is
necessary or advisable) under the laws of any state in which a Mortgaged
Property is located or for the purpose of otherwise conforming to any legal
requirement, restriction or condition in any state in which a Mortgaged Property
is located or in any state in which any portion of the Trust Estate is located.
The Master Servicer shall advise the Trustee when, in its good faith opinion, a
separate trustee or co-trustee is necessary or advisable as aforesaid. The
separate trustees or co-trustees so appointed shall be trustees for the benefit
of all of the Certificateholders and shall have such powers, rights and remedies
as shall be specified in the instrument of appointment; provided, however, that
no such appointment shall, or shall be deemed to, constitute the appointee an
agent of the Trustee. The Seller and the Master Servicer shall join in any such
appointment, but such joining shall not be necessary for the effectiveness of
such appointment.

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

               (i)all powers, duties, obligations and rights conferred upon the
      Trustee, in respect of the receipt, custody and payment of moneys shall be
      exercised solely by the Trustee;

               (ii) all other rights, powers, duties and obligations conferred
      or imposed upon the Trustee shall be conferred or imposed upon and
      exercised or performed by the Trustee and such separate trustee or
      co-trustee jointly, except to the extent that under any law of any
      jurisdiction in which any particular act or acts are to be performed
      (whether as Trustee hereunder or as successor to the Master Servicer
      hereunder) the Trustee shall be incompetent or unqualified to perform such
      act or acts, in which event such rights, powers, duties and obligations
      (including the holding of title to the Trust Estate or any portion thereof
      in any such jurisdiction) shall be exercised and performed by such
      separate trustee or co-trustee;

               (iii) no separate trustee or co-trustee hereunder shall be
      personally liable by reason of any act or omission of any other separate
      trustee or co-trustee hereunder; and

               (iv) the Trustee may at any time accept the resignation of or
      remove any separate trustee or co-trustee so appointed by it, if such
      resignation or removal does not violate the other terms of this Agreement.

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

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

            No separate trustee or co-trustee hereunder shall be required to
meet the terms of eligibility as a successor trustee under Section 8.07
hereunder and no notice to Certificateholders of the appointment thereof shall
be required under Section 8.09 hereof.

            The Trustee agrees to instruct its co-trustees, if any, to the
extent necessary to fulfill such entity's obligations hereunder.

            The Master Servicer shall pay the reasonable compensation of the
co-trustees to the extent, and in accordance with the standards, specified in
Section 8.06 hereof.

            SECTION 8.13 APPOINTMENT OF CUSTODIANS.

            The Trust Administrator may at any time on or after the Closing
Date, with the consent of the Master Servicer and the Seller, appoint one or
more Custodians to hold all or a portion of the Owner Mortgage Loan Files as
agent for the Trust Administrator, by entering into a Custodial Agreement.
Subject to this Article VIII, the Trust Administrator agrees to comply with the
terms of each Custodial Agreement and to enforce the terms and provisions
thereof against the Custodian for the benefit of the Certificateholders. Each
Custodian shall be a depository institution subject to supervision by federal or
state authority, shall have a combined capital and surplus of at least
$10,000,000 and shall be qualified to do business in the jurisdiction in which
it holds any Owner Mortgage Loan File. Each Custodial Agreement may be amended
only as provided in Section 10.01(a).

            SECTION 8.14 TAX MATTERS; COMPLIANCE WITH REMIC PROVISIONS.

            (a) Each of the Trustee, the Trust Administrator and the Master
Servicer covenants and agrees that it shall perform its duties hereunder in a
manner consistent with the REMIC Provisions and shall not knowingly take any
action or fail to take any action that would (i) affect the determination of the
Trust Estate's status as two separate REMICs; or (ii) cause the imposition of
any federal, state or local income, prohibited transaction, contribution or
other tax on either the Upper-Tier REMIC, the Lower-Tier REMIC or the Trust
Estate. The Master Servicer, or, in the case of any tax return or other action
required by law to be performed directly by the Trust Administrator, the Trust
Administrator, shall (i) prepare or cause to be prepared, timely cause to be
signed by the Trustee and file or cause to be filed annual federal and
applicable state and local income tax returns for each of the Upper-Tier REMIC
and the Lower-Tier REMIC using a calendar year as the taxable year and the
accrual method of accounting; (ii) in the first such federal tax returns, make,
or cause to be made, elections satisfying the requirements of the REMIC
Provisions, on behalf of the Trust Estate, to treat each of the Upper-Tier REMIC
and the Lower-Tier REMIC as a REMIC; (iii) prepare, execute and forward, or
cause to be prepared, executed and forwarded, to the Certificateholders all
information reports or tax returns required with respect to the Trust Estate, as
and when required to be provided to the Certificateholders, and to the Internal
Revenue Service and any other relevant governmental taxing authority in
accordance with the REMIC Provisions and any other applicable federal, state or
local laws, including without limitation information reports relating to
"original issue discount" and "market discount" as defined in the Code based
upon the issue prices, prepayment assumption and cash flows provided by the
Seller to the Trust Administrator and calculated on a monthly basis by using the
issue prices of the Certificates; (iv) make available information necessary for
the application of any tax imposed on transferors of residual interests to
"disqualified organizations" (as defined in the REMIC Provisions); (v) file
Forms 8811 and apply for an Employee Identification Number with a Form SS-4 or
any other permissible method and respond to inquiries by Certificateholders or
their nominees concerning information returns, reports or tax returns; (vi)
maintain (or cause to be maintained by the Servicers) such records relating to
the Upper-Tier REMIC and the Lower-Tier REMIC, including but not limited to the
income, expenses, individual Mortgage Loans (including REO Mortgage Loans, other
assets and liabilities of each REMIC, and the fair market value and adjusted
basis of the property of each REMIC determined at such intervals as may be
required by the Code, as may be necessary to prepare the foregoing returns or
information reports; (vii) exercise reasonable care not to allow the creation of
any "interests" in either the Upper-Tier REMIC or the Lower-Tier REMIC within
the meaning of Code Section 860D(a)(2) other than the interests in the
Upper-Tier REMIC represented by the Class I-A-1, Class I-A-2, Class I-A-6, Class
I-A-7, Class I-A-PO, Class I-A-R, Class II-A-1, Class II-A-2, Class II-A-PO
Certificates and each Class A-3, Class A-4 and Class A-5 Component and the Class
I-B-l, Class I-B-2, Class I-B-3, Class I-B-4, Class I-B-5, Class I-B-6, Class
II-B-l, Class II-B-2, Class II-B-3, Class II-B-4, Class II-B-5 and Class II-B-6
Certificates and the interests in the Lower-Tier REMIC represented by the Class
I-A-L1, Class I-A-L2, Class I-A-L3, Class I-A-LPO, Class I-A-LUR, Class II-A-L1,
Class II-A-L3, Class II-A-LPO, Class I-B-L, Class II-B-L Interests and the Class
I-A-LR Certificate; (viii) exercise reasonable care not to allow the occurrence
of any "prohibited transactions" within the meaning of Code Section 860F(a),
unless the Master Servicer shall have provided an Opinion of Counsel to the
Trustee that such occurrence would not (a) result in a taxable gain, (b)
otherwise subject either the Upper-Tier REMIC or Lower-Tier REMIC or the Trust
Estate to tax or (c) cause the Trust Estate to fail to qualify as two separate
REMICs; (ix) exercise reasonable care not to allow either the Upper-Tier REMIC
or the Lower-Tier REMIC to receive income from the performance of services or
from assets not permitted under the REMIC Provisions to be held by a REMIC; (x)
pay (on behalf of the Upper-Tier REMIC or the Lower-Tier REMIC) the amount of
any federal income tax, including, without limitation, prohibited transaction
taxes, taxes on net income from foreclosure property, and taxes on certain
contributions to a REMIC after the Startup Day, imposed on the Upper-Tier REMIC
or Lower-Tier REMIC, as the case may be when and as the same shall be due and
payable (but such obligation shall not prevent the Master Servicer or any other
appropriate Person from contesting any such tax in appropriate proceedings and
shall not prevent the Master Servicer from withholding or depositing payment of
such tax, if permitted by law, pending the outcome of such proceedings); and
(xi) if required or permitted by the Code and applicable law, act as "tax
matters person" for the Upper-Tier REMIC or the Lower-Tier REMIC within the
meaning of Treasury Regulations Section 1.860F-4(d), and the Master Servicer is
hereby designated as agent of the Class I-A-R and Class I-A-LR
Certificateholders for such purpose (or if the Master Servicer is not so
permitted, the Holders of the Class I-A-R and Class I-A-LR Certificates shall be
tax matters persons in accordance with the REMIC Provisions). The Master
Servicer shall be entitled to be reimbursed pursuant to Section 3.02 for any
taxes paid by it pursuant to clause (x) of the preceding sentence, except to the
extent that such taxes are imposed as a result of the bad faith, willful
misfeasance or gross negligence of the Master Servicer in the performance of its
obligations hereunder. The Trustee's sole duties with respect to the Upper-Tier
REMIC and the Lower-Tier REMIC are to sign the tax returns referred to in clause
(i) of the second preceding sentence and to comply with written directions from
the Master Servicer or the Trust Administrator.

            In order to enable the Master Servicer, the Trust Administrator or
the Trustee, as the case may be, to perform its duties as set forth above, the
Seller shall provide, or cause to be provided, to the Master Servicer within ten
days after the Closing Date all information or data that the Master Servicer
determines to be relevant for tax purposes to the valuations and offering prices
of the Certificates, including, without limitation, the price, yield, prepayment
assumption and projected cash flows of each Class of Certificates and the
Mortgage Loans in the aggregate. Thereafter, the Seller shall provide to the
Master Servicer, the Trust Administrator or the Trustee, as the case may be,
promptly upon request therefor, any such additional information or data that the
Master Servicer, the Trust Administrator or the Trustee, as the case may be, may
from time to time, request in order to enable the Master Servicer to perform its
duties as set forth above. The Seller hereby indemnifies the Master Servicer,
the Trust Administrator or the Trustee, as the case may be, for any losses,
liabilities, damages, claims or expenses of the Master Servicer, the Trust
Administrator or the Trustee arising from any errors or miscalculations by the
Master Servicer, the Trust Administrator or the Trustee pursuant to this Section
that result from any failure of the Seller to provide, or to cause to be
provided, accurate information or data to the Master Servicer, the Trust
Administrator or the Trustee, as the case may be, on a timely basis. The Master
Servicer hereby indemnifies the Seller, the Trust Administrator and the Trustee
for any losses, liabilities, damages, claims or expenses of the Seller, the
Trust Administrator or the Trustee arising from the Master Servicer's willful
misfeasance, bad faith or gross negligence in preparing any of the federal,
state and local tax returns of the Upper-Tier REMIC and Lower-Tier REMIC as
described above. In the event that the Trust Administrator prepares any of the
federal, state and local tax returns of the Upper-Tier REMIC or the Lower-Tier
REMIC as described above, the Trust Administrator hereby indemnifies the Seller,
the Master Servicer and the Trustee for any losses, liabilities, damages, claims
or expenses of the Seller, the Master Servicer or the Trustee arising from the
Trust Administrator's willful misfeasance, bad faith or negligence in connection
with such preparation.

            (b) Notwithstanding anything in this Agreement to the contrary, each
of the Master Servicer, the Trust Administrator and the Trustee shall pay from
its own funds, without any right of reimbursement therefor, the amount of any
costs, liabilities and expenses incurred by the Trust Estate (including, without
limitation, any and all federal, state or local taxes, including taxes imposed
on "prohibited transactions" within the meaning of the REMIC Provisions) if and
to the extent that such costs, liabilities and expenses arise from a failure of
the Master Servicer, the Trust Administrator or the Trustee, respectively, to
perform its obligations under this Section 8.14.

            SECTION 8.15 MONTHLY ADVANCES.

            In the event that WFHM fails to make a Periodic Advance required to
be made pursuant to the WFHM Servicing Agreement on or before the Distribution
Date, the Trust Administrator shall make a Periodic Advance as required by
Section 3.03 hereof; provided, however, the Trust Administrator shall not be
required to make such Periodic Advances if prohibited by law or if it determines
that such Periodic Advance would be a Nonrecoverable Advance. With respect to
those Periodic Advances which should have been made by WFHM, the Trust
Administrator shall be entitled, pursuant to Section 3.02(a)(i), (ii) or (v)
hereof, to be reimbursed from the Certificate Account for Periodic Advances and
Nonrecoverable Advances made by it.

acquired upon foreclosure or deed in lieu of foreclosure of any Mortgage Loan;
provided, however, that in no event shall the trust created hereby continue

9.02 and conditioned upon the Pool Scheduled Principal Balance of the Mortgage
Loans as of the Final Distribution Date being less than the amount set forth in
Section 11.18. In the case of any purchase by the Seller pursuant to said clause
(i), the Seller shall provide to the Trust Administrator the certification
required by Section 3.04 and the Trust Administrator and the Custodian shall,
promptly following payment of the purchase price, release to the Seller the
Owner Mortgage Loan Files pertaining to the Mortgage Loans being purchased.

            Notice of any termination, specifying the Final Distribution Date
(which shall be a date that would otherwise be a Distribution Date) upon which
the Certificateholders may surrender their Certificates to the Trust
Administrator for payment of the final distribution and cancellation, shall be
given promptly by the Master Servicer (if it is exercising its right to purchase
the assets of the Trust Estate) or by the Trust Administrator (in any other
case) by letter to Certificateholders mailed not earlier than the 15th day of
the month preceding the month of such final distribution and not later than the
twentieth day of the month of such final distribution specifying (A) the Final
Distribution Date upon which final payment of the Certificates will be made upon
presentation and surrender of Certificates at the office or agency of the Trust
Administrator therein designated, (B) the amount of any such final payment and
(C) that the Record Date otherwise applicable to such Distribution Date is not
applicable, payments being made (except in the case of any Class A Certificate
surrendered on a prior Distribution Date pursuant to Section 4.01) only upon
presentation and surrender of the Certificates at the office or agency of the
Trust Administrator therein specified. If the Master Servicer is obligated to
give notice to Certificateholders as aforesaid, it shall give such notice to the
Trust Administrator and the Certificate Registrar at the time such notice is
given to Certificateholders. In the event such notice is given by the Master
Servicer, the Master Servicer shall deposit in the Certificate Account on or
before the Final Distribution Date in immediately available funds an amount
equal to the purchase price for the assets of the Trust Estate computed as above
provided. Failure to give notice of termination as described herein shall not
entitle a Certificateholder to any interest beyond the interest payable on the
Final Distribution Date.

            Upon presentation and surrender of the Certificates, the Trust
Administrator shall cause to be distributed to Certificateholders on the Final
Distribution Date in proportion to their respective Percentage Interests an
amount equal to (i) as to the Classes of Class A Certificates, the respective
Principal Balance together with any related Class A Unpaid Interest Shortfall
and one month's interest in an amount equal to the respective Interest Accrual
Amount, (ii) as to the Classes of Class B Certificates, the respective Principal
Balance together with any related Class B Unpaid Interest Shortfall and one
month's interest in an amount equal to the respective Interest Accrual Amount
and (iii) as to the Class I-A-R and Class I-A-LR Certificates, the amounts, if
any, which remain on deposit in the Upper-Tier Certificate Account and the
Certificate Account, respectively (other than amounts retained to meet claims)
after application pursuant to clauses (i), (ii) and (iii) above and payment to
the Master Servicer of any amounts it is entitled as reimbursement or otherwise
hereunder. Such amount shall be distributed in respect of interest and principal
in respect of the Uncertificated Lower-Tier Interests in the same amounts as
distributed to their Corresponding Upper-Tier Class or Classes in the manner
specified in Section 4.01(a)(ii). Notwithstanding the foregoing, if the price
paid pursuant to clause (i) of the first paragraph of this Section 9.01, after
reimbursement to the Servicers, the Master Servicer and the Trust Administrator
of any Periodic Advances, is insufficient to pay in full the amounts set forth
in clauses (i), (ii) and (iii) of this paragraph, then any shortfall in the
amount available for distribution to Certificateholders shall be allocated in
reduction of the amounts otherwise distributable on the Final Distribution Date
in the same manner as Realized Losses are allocated pursuant to Sections 4.02(b)
and 4.02(g) hereof. Such distribution on the Final Distribution Date shall be in
lieu of the distribution otherwise required to be made on such Distribution Date
in respect of each Class of Certificates.

            In the event that all of the Certificateholders shall not surrender
their Certificates for final payment and cancellation within three months
following the Final Distribution Date, the Trust Administrator shall on such
date cause all funds, if any, in the Certificate Account not distributed in
final distribution to Certificateholders to be withdrawn therefrom and credited
to the remaining Certificateholders by depositing such funds in a separate
escrow account for the benefit of such Certificateholders, and the Master
Servicer (if it exercised its right to purchase the assets of the Trust Estate)
or the Trust Administrator (in any other case) shall give a second written
notice to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
three months after the second notice all the Certificates shall not have been
surrendered for cancellation, the Trust Administrator may take appropriate
steps, or may appoint an agent to take appropriate steps, to contact the
remaining Certificateholders concerning surrender of their Certificates, and the
cost thereof shall be paid out of the funds on deposit in such escrow account.

            SECTION 9.02 ADDITIONAL TERMINATION REQUIREMENTS.

            In the event of a termination of the Trust Estate upon the exercise
by the Seller of its purchase option as provided in Section 9.01, the Trust
Estate shall be terminated in accordance with the following additional
requirements, unless the Trust Administrator has received an Opinion of Counsel
to the effect that any other manner of termination (i) will constitute a
"qualified liquidation" of the Trust Estate within the meaning of Code Section
860F(a)(4)(A) and (ii) will not subject either the Upper-Tier REMIC or the
Lower-Tier REMIC to federal tax or cause the Trust Estate to fail to qualify as
two separate REMICs at any time that any Certificates are outstanding:

               (i)The notice given by the Master Servicer under Section 9.01
      shall provide that such notice constitutes the adoption of a plan of
      complete liquidation of the Upper-Tier REMIC and the Lower-Tier REMIC as
      of the date of such notice (or, if earlier, the date on which the first
      such notice is mailed to Certificateholders). The Master Servicer shall
      also specify such date in a statement attached to the final tax returns of
      the Upper-Tier REMIC and the Lower-Tier REMIC; and

               (ii) At or after the time of adoption of such a plan of complete
      liquidation and at or prior to the Final Distribution Date, the Trust
      Administrator shall sell all of the assets of the Trust Estate to the
      Seller for cash at the purchase price specified in Section 9.01 and shall
      distribute such cash within 90 days of such adoption in the manner
      specified in Section 9.01.

                            MISCELLANEOUS PROVISIONS

            SECTION 10.01 AMENDMENT.

            (a) This Agreement or any Custodial Agreement may be amended from
time to time by the Seller, the Master Servicer, the Trust Administrator and the
Trustee and with respect to amendments affecting the rights or obligations of
Ambac, with the consent of Ambac, without the consent of any of the
Certificateholders, (i) to cure any ambiguity or mistake, (ii) to correct or
supplement any provisions herein or therein which may be inconsistent with any
other provisions herein or therein or in the related Prospectus, (iii) to
modify, eliminate or add to any of its provisions to such extent as shall be
necessary to maintain the qualification of the Trust Estate as two separate
REMICs at all times that any Certificates are outstanding or to avoid or
minimize the risk of the imposition of any federal tax on the Trust Estate, the
Upper-Tier REMIC or the Lower-Tier REMIC pursuant to the Code that would be a
claim against the Trust Estate, provided that (a) the Trustee and the Trust
Administrator have received an Opinion of Counsel to the effect that such action
is necessary or desirable to maintain such qualification or to avoid or minimize
the risk of the imposition of any such tax and (b) such action shall not, as
evidenced by such Opinion of Counsel, adversely affect in any material respect
the interests of any Certificateholder, (iv) to change the timing and/or nature
of deposits into the Upper-Tier Certificate Account and Certificate Account
provided that such change shall not, as evidenced by an Opinion of Counsel,
adversely affect in any material respect the interests of any Certificateholder,
(v) to modify, eliminate or add to the provisions of Section 5.02 or any other
provisions hereof restricting transfer of the Certificates, provided that the
Master Servicer for purposes of Section 5.02 has determined in its sole
discretion that any such modifications to this Agreement will neither adversely
affect the rating on the Certificates nor give rise to a risk that either the
Upper-Tier REMIC or the Lower-Tier REMIC or any of the Certificateholders will
be subject to a tax caused by a transfer to a non-permitted transferee and (vi)
to make any other provisions with respect to matters or questions arising under
this Agreement or such Custodial Agreement which shall not be materially
inconsistent with the provisions of this Agreement, provided that such action
shall not, as evidenced by an Opinion of Counsel, adversely affect in any
material respect the interests of any Certificateholder. Notwithstanding the
foregoing, any amendment pursuant to clause (iv) or (vi) shall not be deemed to
adversely affect in any material respect the interest of Certificateholders and
no Opinion of Counsel to that effect shall be required if the person requesting
the amendment instead obtains a letter from each Rating Agency stating that the
amendment would not result in the downgrading or withdrawal of the respective
ratings then assigned to the Certificates (without, in the case of the Class A-3
Certificates, giving effect to the guaranty provided by Ambac).

            This Agreement or any Custodial Agreement may also be amended from
time to time by the Seller, the Master Servicer, the Trust Administrator and the
Trustee with the consent of Ambac (only with respect to amendments affecting the
rights or obligations of Ambac) and the Holders of Certificates evidencing in
the aggregate not less than 66-2/3% of the aggregate Voting Interests of each
Class of Certificates affected thereby for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of this
Agreement or such Custodial Agreement or of modifying in any manner the rights
of the Holders of Certificates of such Class; provided, however, that no such
amendment shall (i) reduce in any manner the amount of, or delay the timing of,
payments received on Mortgage Loans which are required to be distributed on any
Certificate without the consent of the Holder of such Certificate, (ii)
adversely affect in any material respect the interest of the Holders of
Certificates of any Class in a manner other than as described in clause (i)
hereof without the consent of Holders of Certificates of such Class evidencing,
as to such Class, Voting Interests aggregating not less than 66-2/3% or (iii)
reduce the aforesaid percentage of Certificates of any Class the Holders of
which are required to consent to any such amendment, without the consent of the
Holders of all Certificates of such Class then outstanding.

            Notwithstanding any contrary provision of this Agreement, neither
the Trustee nor the Trust Administrator shall consent to any amendment to this
Agreement unless it shall have first received an Opinion of Counsel to the
effect that such amendment will not subject either the Upper-Tier REMIC or the
Lower-Tier REMIC to tax or cause either the Upper-Tier REMIC or the Lower-Tier
REMIC to fail to qualify as a REMIC at any time that any Certificates are
outstanding.

            Promptly after the execution of any amendment requiring the consent
of Certificateholders, the Trust Administrator shall furnish written
notification of the substance of such amendment to each Certificateholder.

            It shall not be necessary for the consent of Certificateholders
under this Section 10.01(a) to approve the particular form of any proposed
amendment, but it shall be sufficient if such consent shall approve the
substance thereof. The manner of obtaining such consents and of evidencing the
authorization of the execution thereof by Certificateholders shall be subject to
such reasonable regulations as the Trust Administrator may prescribe.

            (b) Notwithstanding any contrary provision of this Agreement, the
Master Servicer may, from time to time, amend Schedule I hereto without the
consent of any Certificateholder, the Trust Administrator, the Trustee or Ambac;
provided, however, (i) that such amendment does not conflict with any provisions
of the related Servicing Agreement, (ii) that the related Servicing Agreement
provides for the remittance of each type of Unscheduled Principal Receipts
received by such Servicer during the Applicable Unscheduled Principal Receipt
Period (as so amended) related to each Distribution Date to the Master Servicer
no later than the 24th day of the month in which such Distribution Date occurs
and (iii) that such amendment is for the purpose of:

            (a)   changing the Applicable Unscheduled Principal Receipt Period
                  for Exhibit F-1 Mortgage Loans to a Mid-Month Receipt Period
                  with respect to all Unscheduled Principal Receipts; or

            (b)   changing the Applicable Unscheduled Principal Receipt Period
                  for all Mortgage Loans serviced by any Servicer to a Mid-Month
                  Receipt Period with respect to Full Unscheduled Principal
                  Receipts and to a Prior Month Receipt Period with respect to
                  Partial Unscheduled Principal Receipts.

            A copy of any amendment to Schedule I pursuant to this Section
10.01(b) shall be promptly forwarded to the Trust Administrator.

            SECTION 10.02 RECORDATION OF AGREEMENT.

            This Agreement (or an abstract hereof, if acceptable to the
applicable recording office) is subject to recordation in all appropriate public
offices for real property records in all the towns or other comparable
jurisdictions in which any or all of the Mortgaged Properties are situated, and
in any other appropriate public office or elsewhere, such recordation to be
effected by the Master Servicer and at its expense on direction by the Trust
Administrator, but only upon direction accompanied by an Opinion of Counsel to
the effect that such recordation materially and beneficially affects the
interests of the Certificateholders.

            For the purpose of facilitating the recordation of this Agreement as
herein provided and for other purposes, this Agreement may be executed
simultaneously in any number of counterparts, each of which counterparts shall
be deemed to be an original, and such counterparts shall constitute but one and
the same instrument.

            SECTION 10.03 LIMITATION ON RIGHTS OF CERTIFICATEHOLDERS.

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

            Except as otherwise expressly provided herein, no Certificateholder,
solely by virtue of its status as a Certificateholder, shall have any right to
vote or in any manner otherwise control the operation and management of the
Trust Estate, or the obligations of the parties hereto, nor shall anything
herein set forth, or contained in the terms of the Certificates, be construed so
as to constitute the Certificateholders from time to time as partners or members
of an association, nor shall any Certificateholder be under any liability to any
third person by reason of any action taken by the parties to this Agreement
pursuant to any provision hereof.

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

            SECTION 10.04 GOVERNING LAW; JURISDICTION.

            This Agreement shall be construed in accordance with the laws of the
State of New York (without regard to conflicts of laws principles), and the
obligations, rights and remedies of the parties hereunder shall be determined in
accordance with such laws.

            SECTION 10.05 NOTICES.

            All demands, notices and communications hereunder shall be in

communication to Ambac refers to an Event of Default or a claim under the policy
or with respect to which failure on the part of Ambac to respond shall be deemed
to constitute consent or acceptance, then a copy of such notice or other
communication should also be sent to the attention of the General Counsel and
shall be marked to indicate "URGENT MATERIAL ENCLOSED"). Any notice required or
permitted to be mailed to a Certificateholder shall be given by first class
mail, postage prepaid, at the address of such Holder as shown in the Certificate

Agreement shall be conclusively presumed to have been duly given, whether or not
the addressee receives such notice, provided, however, that any demand, notice
or communication to or upon the Seller, the Master Servicer, the Trust
Administrator or the Trustee shall not be effective until received.

            For all purposes of this Agreement, in the absence of actual
knowledge by an officer of the Master Servicer, the Master Servicer shall not be
deemed to have knowledge of any act or failure to act of any Servicer unless
notified thereof in writing by the Trustee, the Trust Administrator, the
Servicer or a Certificateholder.

            SECTION 10.06 SEVERABILITY OF PROVISIONS.

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

            SECTION 10.07 SPECIAL NOTICES TO RATING AGENCIES AND AMBAC.

            (a) The Trust Administrator shall give prompt notice to each Rating
Agency and Ambac of the occurrence of any of the following events of which it

               (i)any  amendment to this  Agreement  pursuant to Section
      10.01(a);

               (ii)     any   sale   or   transfer   of  the   Class   B

described in Section 7.01;

               (vi)     any  notice of  termination  given to the Master
      Servicer pursuant to Section 7.01;

      Servicer pursuant to Section 7.05; or

      Section 9.01.

            (b) The Master Servicer shall give prompt notice to each Rating
Agency and Ambac of the occurrence of any of the following events:

            The Parties intend the conveyance by the Seller to the Trustee of
all of its right, title and interest in and to the Mortgage Loans pursuant to
this Agreement to constitute a purchase and sale and not a loan. Notwithstanding
the foregoing, to the extent that such conveyance is held not to constitute a
sale under applicable law, it is intended that this Agreement shall constitute a
security agreement under applicable law and that the Seller shall be deemed to
have granted to the Trustee a first priority security interest in all of the
Seller's right, title and interest in and to the Mortgage Loans.

housing corporations (the "Group I Mortgage Loans" and "Group II Mortgage
Loans", respectively), formed by Wells Fargo Asset Securities Corporation
(hereinafter called the "Seller", which term includes any successor entity under
the Agreement referred to below). The Trust Estate was created pursuant to a
Pooling and Servicing Agreement dated as of May 25, 2000 (the "Agreement") among
the Seller, Norwest Bank Minnesota, National Association, as master servicer
(the "Master Servicer"), First Union National Bank, as trust administrator (the

which is set forth hereinafter. To the extent not defined herein, the
capitalized terms used herein have the meanings ascribed to such terms in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

            Pursuant to the terms of the Agreement, a distribution will be made
on the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (the "Distribution Date"), commencing on the
first Distribution Date specified above, to the Person in whose name this
Certificate is registered at the close of business on the last Business Day of
the month preceding the month of such distribution, in an amount equal to the
product of the Percentage Interest evidenced by this Certificate and the amount
of interest to be distributed to Holders of Class A-3 Certificates on such
Distribution Date as specified in the Agreement. Distributions of principal will
be made to the Holders of the Class A-3 Certificates as described below and in
the Agreement. Prior to the Distribution Date, if any, on which Ambac fails to
make a required payment under the Policy, distributions in reduction of the
Principal Balance of this Certificate (including amounts paid in respect of such
losses under the Policy as defined below) will be made only in lots equal to
$1,000 initial principal balance and in accordance with the priorities and
procedures set forth in Section 4.07 of the Agreement (i) at the request of
Deceased Holders (ii) at the request of Living Holders and (iii) by random lot.
On and after such Distribution Date, distributions in reduction of principal
balance will be made as provided in the Agreement. Distributions in reduction of
the Principal Balance of certain Classes of Class A Certificates may not
commence on the first Distribution Date specified above. Distributions of
principal will be allocated among the Group II-A Certificates (or their
Components) in accordance with the provisions of the Agreement. For the purposes
of determining distributions of interest and in reduction of Principal Balance,
the Class A-3 Certificates consist of two components (each, a "Component" and
individually, the "Class I-A-3 Component" and the "Class II-A-3 Component"). The
amount of interest which accrues on the Class A-3 Certificates in any month will
equal the sum of the interest which accrues on the Class A-3 Components. The
component rate (the "Component Rate") on each of the Class A-3 Components will
be 7.850% per annum. Interest with respect to each Component will accrue during
each month in an amount equal to the product of (i) 1/12th of the Component Rate
for such Component and (ii) the outstanding Principal Balance of such Component.
The amount of interest which accrues on this Certificate in any month will be
subject to reduction with respect to any Non-Supported Interest Shortfall and
the interest portion of certain Realized Losses allocated to the Class A-3
Certificates, as described in the Agreement.

            The Class A-3 Certificates will be entitled to the benefits of a
Financial Guaranty Insurance Policy issued by Ambac Assurance Corporation (the
"Policy") to the extent described in the Agreement.

            Distributions on this Certificate will be made on behalf of the
Trustee either by the Master Servicer or by a Paying Agent appointed by the
Master Servicer by check mailed to the address of the Person entitled thereto,
as such name and address shall appear on the Certificate Register, unless such
Person is entitled to receive payments by wire transfer in immediately available

housing corporations (the "Group I Mortgage Loans" and "Group II Mortgage
Loans", respectively), formed by Wells Fargo Asset Securities Corporation
(hereinafter called the "Seller", which term includes any successor entity under
the Agreement referred to below). The Trust Estate was created pursuant to a
Pooling and Servicing Agreement dated as of May 25, 2000 (the "Agreement") among
the Seller, Norwest Bank Minnesota, National Association, as master servicer
(the "Master Servicer"), First Union National Bank, as trust administrator (the

capitalized terms used herein have the meanings ascribed to such terms in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of

Components required to be distributed to Holders of the Class A-4 Certificates
on such Distribution Date, subject to adjustment in certain events as specified
in the Agreement. Distributions in reduction of the Principal Balance of certain
Classes of Class A Certificates may not commence on the first Distribution Date

II-A-4 PO Component"). The Class A-4 Certificates are not entitled to
distributions in respect of interest.

            Distributions on this Certificate will be made on behalf of the
Trustee either by the Master Servicer or by a Paying Agent appointed by the
Master Servicer by check mailed to the address of the Person entitled thereto,

42.00000% and a stated redemption price at maturity equal to its initial
principal balance, and is issued with original issue discount ("OID") for

(hereinafter called the "Seller", which term includes any successor entity under
the Agreement referred to below). The Trust Estate was created pursuant to a

Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

            Pursuant to the terms of the Agreement, a distribution will be made
on the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (the "Distribution Date"), commencing on the
first Distribution Date specified above, to the Person in whose name this
Certificate is registered at the close of business on the last Business Day of
the month preceding the month of such distribution, in an amount equal to the

Trustee either by the Master Servicer or by a Paying Agent appointed by the

such distribution and only upon presentation and surrender of this Certificate
at the office or agency specified by the Trust Administrator for that purpose in
the notice of final distribution.

1933, as amended, and any applicable state securities laws or is made in
accordance with said Act and laws. In the event that such a transfer is desired
to be made by the Holder hereof, (i) the transferee will be required to execute
an investment letter in the form described in the Agreement and (ii) if such
transfer is to be made within three years from the later of (a) the date of
initial issuance of the Certificates or (b) the last date on which the Seller or
any affiliate thereof was a Holder of the Certificates proposed to be
transferred, and unless such transfer is made in reliance on Rule 144A of the
Securities Act of 1933, as amended, the Trust Administrator or the Seller may
require the Holder to deliver an opinion of counsel acceptable to and in form
and substance satisfactory to the Trust Administrator and the Seller that such
transfer is exempt (describing the applicable exemption and the basis therefor)
from or is being made pursuant to the registration requirements of the
Securities Act of 1933, as amended, and of any applicable statute of any state.
The Holder hereof desiring to effect such transfer shall, and does hereby agree
to, indemnify the Trustee, the Trust Administrator, the Seller, the Master
Servicer, and any Paying Agent acting on behalf of the Trust Administrator
against any liability that may result if the transfer is not so exempt or is not

transfer, the Trust Administrator will also require (i) a representation letter,
in the form as described in the Agreement, stating either (a) that the
transferee is not a Plan and is not acting on behalf of a Plan or using the
assets of a Plan to effect such purchase or (b) subject to certain conditions
described in the Agreement, that the source of funds used to purchase this
Certificate is an "insurance company general account," or (ii) if such
transferee is a Plan, (a) an opinion of counsel acceptable to and in form and
substance satisfactory to the Trust Administrator and the Seller with respect to
certain matters and (b) such other documentation as the Seller or the Master
Servicer may require, as described in the Agreement.

            Reference is hereby made to the further provisions of this

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

Realized Losses allocated to the Class II-B-1 Certificates, as described in the
Agreement.

            Distributions on this Certificate will be made on behalf of the
Trustee either by the Master Servicer or by a Paying Agent appointed by the
Master Servicer by check mailed to the address of the Person entitled thereto,
as such name and address shall appear on the Certificate Register, unless such
Person is entitled to receive payments by wire transfer in immediately available
funds in accordance with the Pooling and Servicing Agreement and such Person has
notified the Master Servicer pursuant to the Pooling and Servicing Agreement
that such payments are to be made by wire transfer of immediately available
funds. Notwithstanding the above, the final distribution in reduction of the

of funds used to purchase this Certificate is an "insurance company general
account," or (ii) if such transferee is a Plan, (a) an opinion of counsel
acceptable to and in form and substance satisfactory to the Trust Administrator
and the Seller with respect to certain matters and (b) such other documentation
as the Seller or the Master Servicer may require, as described in the Agreement.

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

assets of a Plan to effect such purchase or (b) subject to certain conditions
described in the Agreement, that the source of funds used to purchase this
Certificate is an "insurance company general account," or (ii) if such
transferee is a Plan, (a) an opinion of counsel acceptable to and in form and
substance satisfactory to the Trust Administrator and the Seller with respect to

transferee is a Plan, (a) an opinion of counsel acceptable to and in form and
substance satisfactory to the Trust Administrator and the Seller with respect to
certain matters and (b) such other documentation as the Seller or the Master
Servicer may require, as described in the Agreement.

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

            This Certificate is issued on May 25, 2000, and based on its issue
price of 19.51667%, including accrued interest, and a stated redemption price at

2000 with respect to the offering of the Class A Certificates and Class I-B-1,

Certificates) used to price this Certificate: (i) the amount of OID as a
percentage of the initial principal balance of this Certificate is approximately
80.48333333% and (ii) the annual yield to maturity of this Certificate,

                    WELLS FARGO ASSET SECURITIES CORPORATION
                       MORTGAGE PASS-THROUGH CERTIFICATES

                                  SERIES 2000-2

            This Certificate is one of a duly authorized issue of Certificates
issued in several Classes designated as Mortgage Pass-Through Certificates of
the Series specified hereon (herein collectively called the "Certificates").

            The Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. In the event funds are
advanced with respect to any Mortgage Loan by a Servicer, the Master Servicer or
the Trust Administrator, such advances are reimbursable to such Servicer, the
Master Servicer or the Trust Administrator to the extent provided in the
Agreement, from related recoveries on such Mortgage Loan or from other cash that
would have been distributable to Certificateholders.

            As provided in the Agreement, withdrawals from the Certificate
Account created for the benefit of Certificateholders may be made by the Master
Servicer from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement to a Servicer, the
Master Servicer or the Trust Administrator, as applicable, of advances made by
such Servicer, the Master Servicer or the Trust Administrator.

            The Agreement permits, with certain exceptions therein provided, the
amendment of the Agreement and the modification of the rights and obligations of
the Seller, the Master Servicer, the Trust Administrator and the Trustee and the
rights of the Certificateholders under the Agreement at any time by the Seller,
the Master Servicer, the Trust Administrator and the Trustee with the consent of
the Holders of Certificates evidencing in the aggregate not less than 66 2/3% of
the Voting Interests of each Class of Certificates affected thereby. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange hereof or in lieu
hereof whether or not notation of such consent is made upon the Certificate. The
Agreement also permits the amendment thereof in certain circumstances without
the consent of the Holders of any of the Certificates.

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

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

            No service charge will be made for any such registration of transfer
or exchange, but the Trust Administrator or the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith.

            The Seller, the Master Servicer, the Trust Administrator, the
Trustee and the Certificate Registrar, and any agent of the Seller, the Master
Servicer, the Trust Administrator, the Trustee or the Certificate Registrar, may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and neither the Seller, the Master Servicer, the Trust
Administrator, the Trustee, the Certificate Registrar nor any such agent shall
be affected by notice to the contrary.

            The obligations created by the Agreement in respect of the
Certificates and the Trust Estate created thereby shall terminate upon the last
action required to be taken by the Trust Administrator on the Final Distribution
Date pursuant to the Agreement following the earlier of (i) the payment or other
liquidation (or advance with respect thereto) of the last Mortgage Loan subject
thereto or the disposition of all property acquired upon foreclosure or deed in
lieu of foreclosure of any Mortgage Loan, and (ii) the purchase by the Seller
from the Trust Estate of all remaining Mortgage Loans and all property acquired
in respect of such Mortgage Loans; provided, however, that the Trust Estate will
in no event continue beyond the expiration of 21 years from the death of the
last survivor of the descendants of Joseph P. Kennedy, the late ambassador of
the United States to the Court of St. James, living on the date of the
Agreement. The Agreement permits, but does not require, the Seller to purchase
all remaining Mortgage Loans and all property acquired in respect of any
Mortgage Loan at a price determined as provided in the Agreement. The exercise
of such option will effect early retirement of the Certificates, the Seller's
right to exercise such option being subject to the Pool Scheduled Principal
Balance of the Mortgage Loans as of the Distribution Date upon which the
proceeds of such repurchase are distributed being less than ten percent of the
Cut-Off Date Aggregate Principal Balance.

            WHEREAS, the Seller, the Master Servicer, and the Trust
Administrator and the United States Trust Company of New York, as trustee, have
entered into a Pooling and Servicing Agreement dated as of May 25, 2000 relating
to the issuance of Mortgage Pass-Through Certificates, Series 2000-2 (as in
effect on the date of this Agreement, the "Original Pooling and Servicing
Agreement", and as amended and supplemented from time to time, the "Pooling and
Servicing Agreement"); and

            WHEREAS, the Custodian has agreed to act as agent for the Trust
Administrator for the purposes of receiving and holding certain documents and
other instruments delivered by the Seller under the Pooling and Servicing
Agreement, all upon the terms and conditions and subject to the limitations
hereinafter set forth;

            NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements hereinafter set forth, the Trust Administrator, the
Seller, the Master Servicer and the Custodian hereby agree as follows:

                                    ARTICLE I

                                   Definitions

            Capitalized terms used in this Agreement and not defined herein
shall have the meanings assigned in the Original Pooling and Servicing
Agreement, unless otherwise required by the context herein.

                                   ARTICLE II

                          Custody of Mortgage Documents

            Section 2.1 Custodian to Act as Agent; Acceptance of Custodial
Files. The Custodian, as the duly appointed agent of the Trust Administrator for
these purposes, acknowledges receipt of the Mortgage Notes, the Mortgages, the
assignments and other documents relating to the Mortgage Loans identified on the
schedule attached hereto and declares that it holds and will hold such Mortgage
Notes, Mortgages, assignments and other documents and any similar documents
received by the Trust Administrator subsequent to the date hereof (the
"Custodial Files") as agent for the Trust Administrator, in trust, for the use
and benefit of all present and future Certificateholders.

            Section 2.2 Recordation of Assignments. If any Custodial File
includes one or more assignments to the Trust Administrator of Mortgage Notes
and related Mortgages that have not been recorded, each such assignment shall be
delivered by the Custodian to the Seller for the purpose of recording it in the
appropriate public office for real property records, and the Seller, at no
expense to the Custodian, shall promptly cause to be recorded in the appropriate
public office for real property records each such assignment and, upon receipt
thereof from such public office, shall return each such assignment to the
Custodian.

            Section 2.3 Review of Custodial Files. The Custodian agrees, for the
benefit of Certificateholders, to review, in accordance with the provisions of
Section 2.01 of the Pooling and Servicing Agreement, each Custodial File. If in
performing the review required by this Section 2.3 the Custodian finds any
document or documents constituting a part of a Custodial File to be missing or
defective in any material respect, the Custodian shall promptly so notify the
Seller, the Master Servicer and the Trust Administrator.

            Section 2.4 Notification of Breaches of Representations and
Warranties. Upon discovery by the Custodian of a breach of any representation or
warranty made by the Seller or the Master Servicer as set forth in the Pooling
and Servicing Agreement, the Custodian shall give prompt written notice to the
Seller, the Master Servicer and the Trust Administrator.

            Section 2.5 Custodian to Cooperate; Release of Custodial Files. Upon
the payment in full of any Mortgage Loan, or the receipt by the Master Servicer
of a notification that payment in full will be escrowed in a manner customary
for such purposes, the Master Servicer shall immediately notify the Custodian 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 Certificate Account pursuant to
Section 3.02 of the Pooling and Servicing Agreement have been or will be so
deposited) of a Servicing Officer and shall request delivery to it of the
Custodial File. The Custodian agrees, upon receipt of such certification and
request, promptly to release the related Custodial File to the Master Servicer.

            From time to time as is appropriate for the servicing or foreclosure
of any Mortgage Loan, the Master Servicer shall deliver to the Custodian a
certificate of a Servicing Officer requesting that possession of all, or any
document constituting part of, the Custodial File be released to the Master
Servicer and certifying as to the reason for such release and that such release
will not invalidate any insurance coverage provided in respect of the Mortgage
Loan. With such certificate, the Master Servicer shall deliver to the Custodian
a receipt signed by a Servicing Officer on behalf of the Master Servicer, and
upon receipt of the foregoing, the Custodian shall deliver the Custodial File or
such document to the Master Servicer. The Master Servicer shall cause each
Custodial File or any document therein so released to be returned to the
Custodian when the need therefor by the Master Servicer no longer exists, unless
(i) the Mortgage Loan has been liquidated and the Liquidation Proceeds relating
to the Mortgage Loan have been deposited in the Certificate Account to the
extent required by the Pooling and Servicing Agreement or (ii) the Custodial
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 Master Servicer has
delivered to the Custodian a certificate of a Servicing Officer certifying as to
the name and address of the Person to which such Custodial File or such document
were delivered and the purpose or purposes of such delivery. In the event of the
liquidation of a Mortgage Loan, the Custodian shall deliver such receipt with
respect thereto to the Master Servicer upon deposit of the related Liquidation
Proceeds in the Certificate Account to the extent required by the Pooling and
Servicing Agreement.

            Section 2.6 Assumption Agreements. In the event that any assumption
agreement or substitution of liability agreement is entered into with respect to
any Mortgage Loan subject to this Agreement in accordance with the terms and
provisions of the Pooling and Servicing Agreement, the Master Servicer shall
notify the Custodian that such assumption or substitution agreement has been
completed by forwarding to the Custodian the original of such assumption or
substitution agreement, which copy shall be added to the related Custodial File
and, for all purposes, shall be considered a part of such Custodial File to the
same extent as all other documents and instruments constituting parts thereof.

                                   ARTICLE III

                            Concerning the Custodian

            Section 3.1 Custodian a Bailee and Agent of the Trust Administrator.
With respect to each Mortgage Note, Mortgage and other documents constituting
each Custodian File which are delivered to the Custodian, the Custodian is
exclusively the bailee and agent of the Trust Administrator, holds such
documents for the benefit of Certificateholders and undertakes to perform such
duties and only such duties as are specifically set forth in this Agreement.
Except upon compliance with the provisions of Section 2.5 of this Agreement, no
Mortgage Note, Mortgage or other document constituting a part of a Custodial
File shall be delivered by the Custodian to the Seller or the Master Servicer or
otherwise released from the possession of the Custodian.

            Section 3.2 Indemnification. The Seller hereby agrees to indemnify
and hold the Custodian harmless from and against all claims, liabilities,
losses, actions, suits or proceedings at law or in equity, or any other
expenses, fees or charges of any character or nature, which the Custodian may
incur or with which the Custodian may be threatened by reasons of its acting as
custodian under this Agreement, including indemnification of the Custodian
against any and all expenses, including attorney's fees if counsel for the
Custodian has been approved by the Seller, and the cost of defending any action,
suit or proceedings or resisting any claim. Notwithstanding the foregoing, it is
specifically understood and agreed that in the event any such claim, liability,
loss, action, suit or proceeding or other expense, fees, or charge shall have
been caused by reason of any negligent act, negligent failure to act, or willful
misconduct on the part of the Custodian, or which shall constitute a willful
breach of its duties hereunder, the indemnification provisions of this Agreement
shall not apply.

            Section 3.3 Custodian May Own Certificates. The Custodian in its
individual or any other capacity may become the owner or pledgee of Certificates
with the same rights it would have if it were not Custodian.

            Section 3.4 Master Servicer to Pay Custodian's  Fees and Expenses.
 The Master  Servicer  covenants and agrees to pay to the Custodian  from time
to time, and the Custodian shall be entitled to, reasonable compensation for all
services rendered by it in the exercise and performance of any of the powers and
duties hereunder of the Custodian, and the Master Servicer will pay or reimburse
the Custodian upon its request for all reasonable expenses, disbursements and
advances incurred or made by the Custodian in accordance with any of the
provisions of this Agreement (including the reasonable compensation and the
expenses and disbursements of its counsel and of all persons not regularly in
its employ), except any such expense, disbursement or advance as may arise from
its negligence or bad faith.

            Section 3.5 Custodian May Resign; Trust Administrator May Remove
Custodian. The Custodian may resign from the obligations and duties hereby
imposed upon it as such obligations and duties relate to its acting as Custodian
of the Mortgage Loans. Upon receiving such notice of resignation, the Trust
Administrator shall either take custody of the Custodial Files itself and give
prompt notice thereof to the Seller, the Master Servicer and the Custodian or
promptly appoint a successor Custodian by written instrument, in duplicate, one
copy of which instrument shall be delivered to the resigning Custodian and one
copy to the successor Custodian. If the Trust Administrator shall not have taken
custody of the Custodial Files and no successor Custodian shall have been so
appointed and have accepted resignation, the resigning Custodian may petition
any court of competent jurisdiction for the appointment of a successor
Custodian.

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

            Any resignation or removal of the Custodian and appointment of a
successor Custodian pursuant to any of the provisions of this Section 3.5 shall
become effective upon acceptance of appointment by the successor Custodian. The
Trust Administrator shall give prompt notice to the Seller and the Master
Servicer of the appointment of any successor Custodian. No successor Custodian
shall have been appointed and accepted appointment by the Trust Administrator
without the prior approval of the Seller and the Master Servicer.

            Section 3.6 Merger or Consolidation of Custodian. Any Person into
which the Custodian may be merged or converted or with which it may be
consolidated, or any Person resulting from any merger, conversion or
consolidation to which the Custodian shall be a party, or any Person succeeding
to the business of the Custodian, shall be the successor of the Custodian
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto, anything herein to the contrary
notwithstanding.

            Section 3.7 Representations of the Custodian. The Custodian hereby
represents that it is a depository institution subject to supervision or
examination by a federal or state authority, has a combined capital and surplus
of at least $10,000,000 and is qualified to do business in the jurisdiction in
which it will hold any Custodian File.

                                   ARTICLE IV

                            Miscellaneous Provisions

            Section 4.1 Notices. All notices, requests, consents and demands and
other communications required under this Agreement or pursuant to any other
instrument or document delivered hereunder shall be in writing and, unless
otherwise specifically provided, may be delivered personally, by telegram or
telex, or by registered or certified mail, postage prepaid, return receipt
requested, at the addresses specified on the signature page hereof (unless
changed by the particular party whose address is stated herein by similar notice
in writing), in which case the notice will be deemed delivered when received.

            Section 4.2 Amendments. No modification or amendment of or
supplement to this Agreement shall be valid or effective unless the same is in
writing and signed by all parties hereto, and neither the Seller, the Master
Servicer nor the Trust Administrator shall enter into any amendment hereof
except as permitted by the Pooling and Servicing Agreement. The Trust
Administrator shall give prompt notice to the Custodian of any amendment or
supplement to the Pooling and Servicing Agreement and furnish the Custodian with
written copies thereof.

            SECTION 4.3 GOVERNING LAW. THIS AGREEMENT SHALL BE DEEMED A CONTRACT
MADE UNDER THE LAWS OF THE STATE OF NEW YORK AND SHALL BE CONSTRUED AND ENFORCED
IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

            Section 4.4 Recordation of Agreement. To the extent permitted by
applicable law, this Agreement is subject to recordation in all appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the properties subject to the Mortgages are
situated, and in any other appropriate public recording office or elsewhere,
such recordation to be effected by the Master Servicer and at its expense on
direction by the Trust Administrator, but only upon direction accompanied by an
Opinion of Counsel to the effect that such recordation materially and
beneficially affects the interests of the Certificateholders.

            For the purpose of facilitating the recordation of this Agreement as
herein provided and for other purposes, this Agreement may be executed
simultaneously in any number of counterparts, each of which counterparts shall
be deemed to be an original, and such counterparts shall constitute but one and
the same instrument.

            Section 4.5 Severability of Provisions. If any one or more of the
covenants, agreements, provisions or terms of this Agreement shall be for any
reason whatsoever held invalid, then such covenants, agreements, provisions or
terms shall be deemed severable from the remaining covenants, agreements,
provisions or terms of this Agreement and shall in no way affect the validity or
enforceability of the other provisions of this Agreement or of the Certificates
or the rights of the holders thereof.

                        )  ss.:
COUNTY OF               )


             [NAME OF OFFICER], being first duly sworn, deposes and says:

            1.    That he is [Title of Officer] of [Name of Purchaser] (the
"Purchaser"), a [description of type of entity] duly organized and existing
under the laws of the [State of ] [United States], on behalf of which he makes
this affidavit.

            2.    That  the  Purchaser's  Taxpayer  Identification  Number  is
[             ].

            3.    That the Purchaser is not a "disqualified organization" within
the meaning of Section 860E(e)(5),of the Internal Revenue Code of 1986, as
amended (the "Code"), or an ERISA Prohibited Holder, and will not be a
"disqualified organization" or an ERISA Prohibited Holder, as of [date of
transfer], and that the Purchaser is not acquiring Wells Fargo Asset Securities
Corporation Mortgage Pass-Through Certificates, Series 2000-2, Class [I-A-R]
[I-A-LR] Certificate (the "Class [I-A-R] [I-A-LR] Certificate") for the account
of, or as agent (including a broker, nominee, or other middleman) for, any
person or entity from which it has not received an affidavit substantially in
the form of this affidavit. For these purposes, a "disqualified organization"
means the United States, any state or political subdivision thereof, any foreign
government, any international organization, any agency or instrumentality of any
of the foregoing (other than an instrumentality if all of its activities are
subject to tax and a majority of its board of directors is not selected by such
governmental entity), any cooperative organization furnishing electric energy or
providing telephone service to persons in rural areas as described in Code
Section 1381(a)(2)(C), or any organization (other than a farmers' cooperative
described in Code Section 521) that is exempt from taxation under the Code
unless such organization is subject to the tax on unrelated business income
imposed by Code Section 511. For these purposes, an "ERISA Prohibited Holder"
means an employee benefit plan or other retirement arrangement subject to Title
I of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
or Code Section 4975 or a governmental plan, as defined in Section 3(32) of
ERISA, subject to any federal, state or local law which is, to a material
extent, similar to the foregoing provisions of ERISA or the Code (collectively,
a "Plan") or a Person acting on behalf of or investing the assets of such a
Plan.

            4.    That the Purchaser historically has paid its debts as they
have come due and intends to pay its debts as they come due in the future and
the Purchaser intends to pay taxes associated with holding the Class [I-A-R]
[I-A-LR] Certificate as they become due.

            5.    That the Purchaser understands that it may incur tax
liabilities with respect to the Class [I-A-R] [I-A-LR] Certificate in excess of
cash flows generated by the Class [I-A-R] [I-A-LR] Certificate.

            6.    That the Purchaser will not transfer the Class [I-A-R]
[I-A-LR] Certificate to any person or entity from which the Purchaser has not
received an affidavit substantially in the form of this affidavit and as to
which the Purchaser has actual knowledge that the requirements set forth in
paragraph 3, 4 or 7 hereof are not satisfied or that the Purchaser has reason to
know does not satisfy the requirements set forth in paragraph 4 hereof.

            7.    That the Purchaser (i) is a U.S. Person or (ii) is a person
other than a U.S. Person (a "Non-U.S. Person") that holds the Class [I-A-R]
[I-A-LR] Certificate in connection with the conduct of a trade or business
within the United States and has furnished the transferor and the Trust
Administrator with an effective Internal Revenue Service Form 4224 or successor
form at the time and in the manner required by the Code or (iii) is a Non-U.S.
Person that has delivered to both the transferor and the Trust Administrator an
opinion of a nationally recognized tax counsel to the effect that the transfer
of the Class [I-A-R] [I-A-LR] Certificate to it is in accordance with the
requirements of the Code and the regulations promulgated thereunder and that
such transfer of the Class [I-A-R] [I-A-LR] Certificate will not be disregarded
for federal income tax purposes. "U.S. Person" means a citizen or resident of
the United States, a corporation or partnership (unless, in the case of a
partnership, Treasury regulations are adopted that provide otherwise) created or
organized in or under the laws of the United States, any state thereof or the
District of Columbia, including an entity treated as a corporation or
partnership for federal income tax purposes, an estate whose income is subject
to United States federal income tax regardless of its source, or a trust if a
court within the United States is able to exercise primary supervision over the
administration of such trust, and one or more such U.S. Persons have the
authority to control all substantial decisions of such trust (or, to the extent
provided in applicable Treasury regulations, certain trusts in existence on
August 20, 1996 which are eligible to elect to be treated as U.S. Persons).

            8.    That the Purchaser agrees to such amendments of the Pooling
and Servicing Agreement as may be required to further effectuate the
restrictions on transfer of the Class [I-A-R] [I-A-LR] Certificate to such a
"disqualified organization," an agent thereof, an ERISA Prohibited Holder or a
person that does not satisfy the requirements of paragraph 4, paragraph 5 and
paragraph 7 hereof.

            9.    That the Purchaser consents to the designation of the Master
Servicer as its agent to act as "tax matters person" of the [Upper-Tier REMIC]
[Lower-Tier REMIC] pursuant to Section 3.01 of the Pooling and Servicing
Agreement, and if such designation is not permitted by the Code and applicable
law, to act as tax matters person if requested to do so.

            [(d) The Purchaser is a "Qualified Institutional Buyer" within the

            (e) The Purchaser confirms that (a) it has received and reviewed a

thereto, and obtain any additional information (including documents) relevant to
its decision to purchase the Class [I-B-4] [I-B-5] [I-B-6] [II-B-4] [II-B-5]
[II-B-6] Certificates that the Seller possesses or can possess without

            (f) Either (i) the Purchaser is not an employee benefit plan or

Class [I-B-4] [I-B-5] [I-B-6] [II-B-4] [II-B-5] [II-B-6] Certificate is an
"insurance company general account" (as such term is defined in Section V(e) of
Prohibited Transaction Class Exemption 95-60 ("PTE 95-60"), 60 Fed. Reg. 35925
(July 12, 1995), (B) there is no Plan with respect to which the amount of such
general account's reserves and liabilities for the contract(s) held by or on
behalf of such Plan and all other Plans maintained by the same employer (or
affiliate thereof as defined in Section V(a)(1) of PTE 95-60) or by the same
employee organization exceeds 10% of the total of all reserves and liabilities
of such general account (as such amounts are determined under Section I(a) of
PTE 95-60) at the date of acquisition and (C) the purchase and holding of such
Class [I-B-4] [I-B-5] [I-B-6] [II-B-4] [II-B-5] [II-B-6] Certificates are
covered by Sections I and III of PTE 95-60 or (iii) the Purchaser has provided
(a) a "Benefit Plan Opinion" satisfactory to the Seller and the Trust
Administrator of the Trust Estate and (b) such other opinions of counsel,
officers' certificates and agreements as the Seller or the Master Servicer may
have required. A Benefit Plan Opinion is an opinion of counsel to the effect
that the proposed transfer will not cause the assets of the Trust Estate to be
regarded as "plan assets" and subject to the prohibited transaction provisions
of ERISA, the Code or Similar Law and will not subject the Trust Administrator,
the Trustee, the Seller or the Master Servicer to any obligation in addition to
those undertaken in the Pooling and Servicing Agreement (including any liability
for civil penalties or excise taxes imposed pursuant to ERISA, Section 4975 of
the Code or Similar Law).

            (g) If the Purchaser is a depository institution subject to the
jurisdiction of the Office of the Comptroller of the Currency ("OCC"), the Board
of Governors of the Federal Reserve System ("FRB"), the Federal Deposit
Insurance Corporation ("FDIC"), the Office of Thrift Supervision ("OTS") or the
National Credit Union Administration ("NCUA"), the Purchaser has reviewed the
"Supervisory Policy Statement on Securities Activities" dated January 28, 1992
of the Federal Financial Institutions Examination Council and the April 15, 1994
Interim Revision thereto as adopted by the OCC, FRB, FDIC, OTS and NCUA (with
modifications as applicable), as appropriate, other applicable investment
authority, rules, supervisory policies and guidelines of these agencies and, to
the extent appropriate, state banking authorities and has concluded that its
purchase of the Class [I-B-4] [I-B-5] [I-B-6] [II-B-4] [II-B-5] [II-B-6]
Certificates is in compliance therewith.

            Section 3.__Transfer of Class [I-B-4] [I-B-5] [I-B-6] [II-B-4]
[II-B-5] [II-B-6] Certificates.

            (a) The Purchaser understands that the Class [I-B-4] [I-B-5] [I-B-6]
[II-B-4] [II-B-5] [II-B-6] Certificates have not been registered under the
Securities Act of 1933 (the "Act") or any state securities laws and that no
transfer may be made unless the Class [I-B-4] [I-B-5] [I-B-6] [II-B-4] [II-B-5]
[II-B-6] Certificates are registered under the Act and applicable state law or
unless an exemption from registration is available. The Purchaser further
understands that neither the Seller, the Master Servicer nor the Trust
Administrator is under any obligation to register the Class [I-B-4] [I-B-5]
[I-B-6] [II-B-4] [II-B-5] [II-B-6] Certificates or make an exemption available.
In the event that such a transfer is to be made in reliance upon an exemption
from the Act or applicable state securities laws, (i) the Trust Administrator
shall require, in order to assure compliance with such laws, that the
Certificateholder's prospective transferee certify to the Seller and the Trust
Administrator as to the factual basis for the registration or qualification
exemption relied upon, and (ii) unless the transferee is a "Qualified
Institutional Buyer" within the meaning of Rule 144A of the Act, the Trust
Administrator or the Seller may, if such transfer is made within three years
from the later of (a) the Closing Date or (b) the last date on which the Seller
or any affiliate thereof was a holder of the Certificates proposed to be
transferred, require an Opinion of Counsel that such transfer may be made
pursuant to an exemption from the Act and state securities laws, which Opinion
of Counsel shall not be an expense of the Trust Administrator, the Master
Servicer or the Seller. Any such Certificateholder desiring to effect such
transfer shall, and does hereby agree to, indemnify the Trustee, the Trust
Administrator, the Master Servicer, any Paying Agent acting on behalf of the
Trust Administrator and the Seller against any liability that may result if the
transfer is not so exempt or is not made in accordance with such federal and
state laws.

            (b) No transfer of a Class [I-B-4] [I-B-5] [I-B-6] [II-B-4] [II-B-5]
[II-B-6] Certificate shall be made unless the transferee provides the Seller and
the Trust Administrator with a Transferee's Letter, substantially in the form of
this Agreement.

            (c) The Purchaser acknowledges that its Class [I-B-4] [I-B-5]
[I-B-6] [II-B-4] [II-B-5] [II-B-6] Certificates bear a legend setting forth the
applicable restrictions on transfer.

"Class [I-B-1] [I-B-2] [I-B-3] [II-B-1] [II-B-2] [II-B-3] Certificates") in the
principal amount of $___________. In doing so, the Purchaser hereby acknowledges
and agrees as follows:

            Section 1.  Definitions. Each capitalized term used herein and not
otherwise defined herein shall have the meaning ascribed to it in the Pooling
and Servicing Agreement, dated as of May 25, 2000 (the "Pooling and Servicing
Agreement") among Wells Fargo Asset Securities Corporation, as seller (the
"Seller"), Norwest Bank Minnesota, National Association, as master servicer (the

            Section 2.  Representations and Warranties of the Purchaser. In
connection with the proposed transfer, the Purchaser represents and warrants to
the Seller, the Master Servicer and the Trust Administrator that:

            Either (i) the Purchaser is not an employee benefit plan or other
retirement arrangement subject to Title I of the Employee Retirement Income
Security Act of 1974, as amended, ("ERISA"), or Section 4975 of the Internal
Revenue Code of 1986, as amended (the "Code"), or a governmental plan, as
defined in Section 3(32) of ERISA subject to any federal, state or local law
("Similar Law") which is, to a material extent, similar to the foregoing
provisions of ERISA or the Code (collectively, a "Plan"), an agent acting on
behalf of a Plan, or a person utilizing the assets of a Plan or (ii) if the
Purchaser is an insurance company, (A) the source of funds used to purchase the
Class [I-B-1] [I-B-2] [I-B-3] [II-B-1] [II-B-2] [II-B-3] Certificate is an
"insurance company general account" (as such term is defined in Section V(e) of

(July 12, 1995), (B) there is no Plan with respect to which the amount of such
general account's reserves and liabilities for the contract(s) held by or on
behalf of such Plan and all other Plans maintained by the same employer (or
affiliate thereof as defined in Section V(a)(1) of PTE 95-60) or by the same

"Benefit Plan Opinion" satisfactory to the Seller and the Trust Administrator of
the Trust Estate and (b) such other opinions of counsel, officers' certificates
and agreements as the Seller or the Master Servicer may have required. A Benefit
Plan Opinion is an opinion of counsel to the effect that the proposed transfer
will not cause the assets of the Trust Estate to be regarded as "plan assets"
and subject to the prohibited transaction provisions of ERISA, the Code or
Similar Law and will not subject the Trust Administrator, the Trustee, the
Seller or the Master Servicer to any obligation in addition to those undertaken
in the Pooling and Servicing Agreement (including any liability for civil
penalties or excise taxes imposed pursuant to ERISA, Section 4975 of the Code or
Similar Law).

            IN WITNESS WHEREOF, the undersigned has caused this Agreement to be
validly executed by its duly authorized representative as of the day and the

                          SPECIAL SERVICING PROCEDURES

            Section 2.01      Reports and Notices

            (a)___In connection with the performance of its duties under the
Pooling and Servicing Agreement relating to the realization upon defaulted
Mortgage Loans, the Company as Master Servicer shall provide to the Purchaser
the following notices and reports:

               (i)Within five Business Days after each Distribution Date (or
      included in or with the monthly statements to Certificateholders pursuant
      to the Pooling and Servicing Agreement), the Company, shall provide to the
      Purchaser a report, using the same methodology and calculations in its
      standard servicing reports, indicating for the Trust Estate the number of
      Mortgage Loans that are (A) thirty days, (B) sixty days, (C) ninety days
      or more delinquent or (D) in foreclosure, and indicating for each such
      Mortgage Loan the loan number and outstanding principal balance.

               (ii) Prior to the Commencement of Foreclosure in connection with
      any Mortgage Loan, the Company shall cause (to the extent that the Company
      as Master Servicer is granted such authority in the related Servicing
      Agreement) the Servicer to provide the Purchaser with a notice (sent by
      telecopier) of such proposed and imminent foreclosure, stating the loan
      number and the aggregate amount owing under the Mortgage Loan. Such notice
      may be provided to the Purchaser in the form of a copy of a referral
      letter from such Servicer to an attorney requesting the institution of
      foreclosure.

            (b) If requested by the Purchaser, the Company shall cause the
Servicer (to the extent that the Company as Master Servicer is granted such
authority in the related Servicing Agreement) to make its servicing personnel
available (during their normal business hours) to respond to reasonable
inquiries, by phone or in writing by facsimile, electronic, or overnight mail
transmission, by the Purchaser in connection with any Mortgage Loan identified
in a report under subsection (a) (i) (B), (a) (i) (C), (a) (i) (D), or (a) (ii)
which has been given to the Purchaser; provided, that (1) the related Servicer
shall only be required to provide information that is readily accessible to its
servicing personnel and is non-confidential and (2) the related Servicer shall
respond within five Business Days orally or in writing by facsimile
transmission.

            (c) In addition to the foregoing, the Company shall cause the
Servicer (to the extent that the Company as Master Servicer is granted such
authority in the related Servicing Agreement) to provide to the Purchaser such
information as the Purchaser may reasonably request provided, however, that such
information is consistent with normal reporting practices, concerning each
Mortgage Loan that is at least ninety days delinquent and each Mortgage Loan
which has become real estate owned, through the final liquidation thereof;
provided, that the related Servicer shall only be required to provide
information that is readily accessible to its servicing personnel and is
non-confidential provided, however, that the Purchaser will reimburse the
Company and the related Servicer for any out of pocket expenses.

            Section 2.02      Purchaser's   Election  to  Delay  Foreclosure

Proceedings

            (a) The Purchaser shall be deemed to direct the Company to direct
(to the extent that the Company as Master Servicer is granted such authority in
the related Servicing Agreement) the related Servicer that in the event that the
Company does not receive written notice of the Purchaser's election pursuant to
subsection (b) below within 24 hours (exclusive of any intervening non-Business
Days) of transmission of the notice provided by the Company under Section 2.01
(a) (ii) subject to extension as set forth in Section 2.02(b), the related
Servicer may proceed with the Commencement of Foreclosure in respect of such
Mortgage Loan in accordance with its normal foreclosure policies without further
notice to the Purchaser. Any foreclosure that has been initiated may be
discontinued (i) without notice to the Purchaser if the Mortgage Loan has been
brought current or if a refinancing or prepayment occurs with respect to the
Mortgage Loan (including by means of a short payoff approved by the related
Servicer) or (ii) if the related Servicer has reached the terms of a forbearance
agreement with the borrower. In the latter case, the related Servicer may
complete such forbearance agreement unless instructed otherwise by the Purchaser
within two Business Days notification.

            (b) In connection with any Mortgage Loan with respect to which a
notice under Section 2.01(a)(ii) has been given to the Purchaser, the Purchaser
may elect to instruct the Company to cause, to the extent that the Company as
Master Servicer is granted such authority in the related Servicing Agreement,
the related Servicer to delay the Commencement of Foreclosure until such time as
the Purchaser determines that the related Servicer may proceed with the
Commencement of Foreclosure. Such election must be evidenced by written notice
received within 24 hours (exclusive of any intervening non-Business Days) of
transmission of the notice provided by the Company under Section 2.01(a)(ii).
Such 24 hour period shall be extended for no longer than an additional four
Business Days after the receipt of the information if the Purchaser requests
additional information related to such foreclosure; provided, however, that the
Purchaser will have at least one Business Day to respond to any requested
additional information. Any such additional information shall be provided only
to the extent it (i) is not confidential in nature and (ii) is obtainable by the
related Servicer from existing reports, certificates or statements or is
otherwise readily accessible to its servicing personnel. The Purchaser agrees
that it has no right to deal with the mortgagor during such period. However, if
such servicing activities include acceptance of a deed-in-lieu of foreclosure or
short payoff, the Purchaser will be notified and given two Business Days to
respond.

            (c) With respect to any Mortgage Loan as to which the Purchaser has
made an Election to Delay Foreclosure, the Purchaser shall obtain a Current
Appraisal as soon as practicable, but in no event more than 15 business days
thereafter, and shall provide the Company with a copy of such Current Appraisal.

            (d) Within two Business Days of making any Election to Delay
Foreclosure, the Purchaser shall remit by wire transfer to the Company, for
deposit in the Collateral Fund, an amount, as calculated by the Company, equal
to the sum of (i) 125% of the greater of the unpaid principal balance of the
Mortgage Loan and the value shown in the Current Appraisal referred to in
subsection (c) above (or, if such Current Appraisal has not yet been obtained,
the Company's estimate thereof, in which case the required deposit under this
subsection shall be adjusted upon obtaining such Current Appraisal), and (ii)
three months' interest on the Mortgage Loan at the applicable Mortgage Interest
Rate. If any Election to Delay Foreclosure extends for a period in excess of
three months (such excess period being referred to herein as the "Excess
Period"), within two Business Days the Purchaser shall remit by wire transfer in
advance to the Company for deposit in the Collateral Fund the amount of each
additional month's interest, as calculated by the Company, equal to interest on
the Mortgage Loan at the applicable Mortgage Interest Rate for the Excess
Period. The terms of this Agreement will no longer apply to the servicing of any
Mortgage Loan upon the failure of the Purchaser to deposit any of the above
amounts relating to the Mortgage Loan within two Business Days of the Election
to Delay Foreclosure or within two Business Days of the commencement of the
Excess Period subject to Section 3.01.

            (e) With respect to any Mortgage Loan as to which the Purchaser has
made an Election to Delay Foreclosure, the Company may withdraw from the
Collateral Fund from time to time amounts necessary to reimburse the related
Servicer for all related Monthly Advances and Liquidation Expenses thereafter
made by such Servicer in accordance with the Pooling and Servicing Agreement and
the related Servicing Agreement. To the extent that the amount of any such
Liquidation Expenses is determined by the Company based on estimated costs, and
the actual costs are subsequently determined to be higher, the Company may
withdraw the additional amount from the Collateral Fund. In the event that the
Mortgage Loan is brought current by the mortgagor and the foreclosure action is
discontinued, the amounts so withdrawn from the Collateral Fund shall be
redeposited if and to the extent that reimbursement therefor from amounts paid
by the mortgagor is not prohibited pursuant to the Pooling and Servicing
Agreement or the related Servicing Agreement, applicable law or the related
mortgage note. Except as provided in the preceding sentence, amounts withdrawn
from the Collateral Fund to cover Monthly Advances and Liquidation Expenses
shall not be redeposited therein or otherwise reimbursed to the Purchaser. If
and when any such Mortgage Loan is brought current by the mortgagor, all amounts
remaining in the Collateral Fund in respect of such Mortgage Loan (after
adjustment for all permitted withdrawals and deposits pursuant to this
subsection) shall be released to the Purchaser.

            (f) With respect to any Mortgage Loan as to which the Purchaser has
made an Election to Delay Foreclosure, the related Servicer shall continue to
service the Mortgage Loan in accordance with its customary procedures (other
than the delay in Commencement of Foreclosure as provided herein). If and when
the Purchaser shall notify the Company that it believes that it is appropriate
to do so, the related Servicer may proceed with the Commencement of Foreclosure.
In any event, if the Mortgage Loan is not brought current by the mortgagor by
the time the loan becomes 6 months delinquent, the Purchaser's election shall no
longer be effective and at the Purchaser's option, either (i) the Purchaser
shall purchase the Mortgage Loan from the related Trust Estate at a purchase
price equal to the fair market value as shown on the Current Appraisal, to be
paid by (x) applying any balance in the Collateral Fund to such to such purchase
price, and (y) to the extent of any deficiency, by wire transfer of immediately
available funds from the Purchaser to the Company for deposit in the related
Certificate Account; or (ii) the related Servicer shall proceed with the
Commencement of Foreclosure.

            (g) Upon the occurrence of a liquidation with respect to any
Mortgage Loan as to which the Purchaser made an Election to Delay Foreclosure
and as to which the related Servicer proceeded with the Commencement of
Foreclosure in accordance with subsection (f) above, the Company shall calculate
the amount, if any, by which the value shown on the Current Appraisal obtained
under subsection (c) exceeds the actual sales price obtained for the related
Mortgaged Property (net of Liquidation Expenses and accrued interest related to
the extended foreclosure period), and the Company shall withdraw the amount of
such excess from the Collateral Fund, shall remit the same to the Trust Estate
and in its capacity as Master Servicer shall apply such amount as additional
Liquidation Proceeds pursuant to the Pooling and Servicing Agreement. After
making such withdrawal, all amounts remaining in the Collateral Fund in respect
of such Mortgage Loan (after adjustment for all permitted withdrawals and
deposits pursuant to this Agreement) shall be released to the Purchaser.

            Section 2.03      Purchaser's  Election to Commence  Foreclosure

Proceedings

            (a) In connection with any Mortgage Loan identified in a report
under Section 2.01(a)(i)(B), the Purchaser may elect to instruct the Company to
cause, to the extent that the Company as Master Servicer is granted such
authority in the related Servicing Agreement, the related Servicer to proceed
with the Commencement of Foreclosure as soon as practicable. Such election must
be evidenced by written notice received by the Company by 5:00 p.m., New York
City time, on the third Business Day following the delivery of such report under
Section 2.01(a)(i).

            (b) Within two Business Days of making any Election to Foreclose,
the Purchaser shall remit to the Company, for deposit in the Collateral Fund, an
amount, as calculated by the Company, equal to 125% of the current unpaid
principal balance of the Mortgage Loan and three months interest on the Mortgage
Loan at the applicable Mortgage Interest Rate. If and when any such Mortgage
Loan is brought current by the mortgagor, all amounts in the Collateral Fund in
respect of such Mortgage Loan (after adjustment for all permitted withdrawals
and deposits pursuant to this Agreement) shall be released to the Purchaser if
and to the extent that reimbursement therefor from amounts paid by the mortgagor
is not prohibited pursuant to the Pooling and Servicing Agreement or the related
Servicing Agreement, applicable law or the related mortgage note. The terms of
this Agreement will no longer apply to the servicing of any Mortgage Loan upon
the failure of the Purchaser to deposit the above amounts relating to the
Mortgage Loan within two Business Days of the Election to Foreclose subject to
Section 3.01.

            (c) With respect to any Mortgage Loan as to which the Purchaser has
made an Election to Foreclose, the related Servicer shall continue to service
the Mortgage Loan in accordance with its customary procedures (other than
Commencement of Foreclosure as provided herein). In connection therewith, the
Company shall have the same rights to make withdrawals for Monthly Advances and
Liquidations Expenses from the Collateral Fund as are provided under Section
2.02(e), and the Company shall make reimbursements thereto to the limited extent
provided under such subsection in accordance with its customary procedures. The
Company shall not be required to cause, to the extent that the Company as Master
Servicer is granted such authority in the related Servicing Agreement, the
related Servicer to proceed with the Commencement of Foreclosure if (i) the same
is stayed as a result of the mortgagor's bankruptcy or is otherwise barred by
applicable law, or to the extent that all legal conditions precedent thereto
have not yet been complied with, or (ii) the Company believes there is a breach
of representations or warranties by the Company, a Servicer, or a Seller, which
may result in a repurchase or substitution of such Mortgage Loan, or (iii) the
Company or related Servicer reasonably believes the Mortgaged Property may be
contaminated with or affected by hazardous wastes or hazardous substances (and,
without limiting the related Servicer's right not to proceed with the
Commencement of Foreclosure, the Company supplies the Purchaser with information
supporting such belief). Any foreclosure that has been initiated may be
discontinued (x) without notice to the Purchaser if the Mortgage Loan has been
brought current or if a refinancing or prepayment occurs with respect to the
Mortgage Loan (including by means of a short payoff approved by the Purchaser)
or (y) with notice to the Purchaser if the related Servicer has reached the
terms of a forbearance agreement unless instructed otherwise by the Purchaser
within two Business Days of such notification. Any such instruction shall be
based upon a decision that such forbearance agreement is not in conformity with
reasonable servicing practices.

            (d) Upon the occurrence of a liquidation with respect to any
Mortgage Loan as to which the Purchaser made an Election to Foreclose and as to
which the related Servicer proceeded with the Commencement of Foreclosure in
accordance with subsection (c) above, the Company shall calculate the amount, if
any, by which the unpaid principal balance of the Mortgage Loan at the time of
liquidation (plus all unreimbursed interest and servicing advances and
Liquidation Expenses in connection therewith other than those paid from the
Collateral Fund) exceeds the actual sales price obtained for the related
Mortgaged Property, and the Company shall withdraw the amount of such excess
from the Collateral Fund, shall remit the same to the Trust Estate and in its
capacity as Master Servicer shall apply such amount as additional Liquidation

respect to the Collateral Fund shall be that of the Purchaser. All distributions
from the Trust Fund to the Collateral Fund shall be treated as distributed to

            Upon the termination of this Agreement and the liquidation of all
Mortgage Loans as to which the Purchaser has made any Election to Delay
Foreclosure or any Election to Foreclose pursuant to Section 2.04 hereof, the
Company shall distribute or cause to be distributed to the Purchaser all amounts
remaining in the Collateral Fund (after adjustment for all deposits and
permitted withdrawals pursuant to this Agreement) together with any investment
earnings thereon. In the event the Purchaser has made any Election to Delay
Foreclosure or any Election to Foreclose, prior to any distribution to the
Purchaser of all amounts remaining in the Collateral Fund, funds in the
Collateral Fund shall be applied consistent with the terms of this Agreement.

            Section 3.02      Collateral Fund Permitted Investments

            The Company shall, at the written direction of the Purchaser, invest

definition of Collateral Fund Permitted Investments in its discretion.

            All income and gain realized from any investment as well as any
interest earned on deposits in the Collateral Fund (net of any losses on such
investments) and any payments of principal made in respect of any Collateral
Fund Permitted Investment shall be deposited in the Collateral Fund upon
receipt. All costs and realized losses associated with the purchase and sale of
Collateral Fund Permitted Investments shall be borne by the Purchaser and the
amount of net realized losses shall be deposited by the Purchaser in the
Collateral Fund promptly upon realization. The Company shall periodically (but
not more frequently than monthly) distribute to the Purchaser upon request an
amount of cash, to the extent cash is available therefore in the Collateral
Fund, equal to the amount by which the balance of the Collateral Fund, after
giving effect to all other distributions to be made from the Collateral Fund on
such date, exceeds the Required Collateral Fund Balance. Any amounts so
distributed shall be released from the lien and security interest of this
Agreement.

            Section 3.03      Grant of Security Interest

            The Purchaser hereby grants to the Company for the benefit of the
Certificateholders under the Pooling and Servicing Agreement a security interest
in and lien on all of the Purchaser's right, title and interest, whether now
owned or hereafter acquired, in and to: (1) the Collateral Fund, (2) all amounts
deposited in the Collateral Fund and Collateral Fund Permitted Investments in
which such amounts are invested (and the distributions and proceeds of such
investments) and (3) all cash and non-cash proceeds of any of the foregoing,
including proceeds of the voluntary conversion thereof (all of the foregoing
collectively, the "Collateral").

            The Purchaser acknowledges the lien on and the security interest in
the Collateral for the benefit of the Certificateholders. The Purchaser shall
take all actions requested by the Company as may be reasonably necessary to
perfect the security interest created under this Agreement in the Collateral and
cause it to be prior to all other security interests and liens, including the
execution and delivery to the Company for filing of appropriate financing
statements in accordance with applicable law. The Company shall file appropriate
continuation statements, or appoint an agent on its behalf to file such
statements, in accordance with applicable law.

            Section 3.04      Collateral Shortfalls

            In the event that amounts on deposit in the Collateral Fund at any
time are insufficient to cover any withdrawals therefrom that the Company is
then entitled to make hereunder, the Purchaser shall be obligated to pay such
amounts to the Company immediately upon demand. Such obligation shall constitute
a general corporate obligation of the Purchaser. The failure to pay such amounts
within two Business Days of such demand (except for amounts to cover interest on
a Mortgage Loan pursuant to Sections 2.02(d) and 2.03 (b)), shall cause an
immediate termination of the Purchaser's right to make any Election to Delay
Foreclosure or Election to Foreclose and the Company's obligations under this
Agreement with respect to all Mortgage Loans to which such insufficiencies
relate, without the necessity of any further notice or demand on the part of the
Company.
