waiver or other action provided by this Agreement to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing. Except as herein otherwise expressly provided, such action
shall become effective when such instrument or instruments are delivered to the
Trustee. Proof of execution of any such instrument or of a writing appointing
any such agent shall be sufficient for any purpose of this Agreement and
conclusive in favor of the Trustee, if made in the manner provided in this
Section 1.02. The Trustee shall promptly notify the Master Servicer in writing
of the receipt of any such instrument or writing.

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

            (c) The ownership of Certificates (whether or not such Certificates

waiver or other action of the Holder of any Certificate shall bind every future
Holder of the same Certificate and the Holder of every Certificate issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee, the
Seller or the Master Servicer in reliance thereon, whether or not notation of
such action is made upon such Certificate.

            Nothing in this Agreement or in the Certificates, express or
implied, shall give to any Person, other than the parties to this Agreement and

                          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, and
(d) 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 Trustee, 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 Trustee 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 Trustee 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 Trustee 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 Trustee 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 Trustee 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 Trustee 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 Trustee the assignment of the Mortgage Loan from the
Seller to the Trustee 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 Trustee and the
Trustee shall within five Business Days (or such other reasonable period of time
mutually agreed upon by the Master Servicer and the Trustee) of its receipt of
such notice deliver each previously unrecorded assignment to the related
Servicer for recordation.

            SECTION 2.02      ACCEPTANCE BY TRUSTEE.

            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
Trustee 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 Trustee 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 Trustee 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 Trustee 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 Trustee'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 Trustee 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 Trustee 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 Trustee 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 Trustee 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 or the Trustee on behalf of the
Certificateholders. The failure of the Trustee 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 Trustee 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 Trustee appoints a Custodian to
hold the Mortgage Notes, the Mortgages, the assignments and other documents
related to the Mortgage Loans received by 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 for the benefit of Certificateholders that, as of the date of execution
of this Agreement:

               (i) The Master Servicer is a national banking association duly
      chartered and validly existing in good standing under the laws of the
      United States;

               (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 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 this Agreement.

            It is understood and agreed that the representations and warranties
set forth in this Section 2.03(a) shall survive delivery of the respective Owner
Mortgage Loan Files to the Trustee or the Custodian.

            (b) The Seller hereby represents and warrants to the Trustee for the
benefit of Certificateholders that, as of the date of execution of this
Agreement, with respect to the Mortgage Loans, or each Mortgage Loan, as the
case may be:

               (i) The information set forth in the Mortgage Loan Schedule was

      and assign the same;

               (iii) The Mortgage is a valid, subsisting and enforceable first
      lien on the property therein described, and the Mortgaged Property is free
      and clear of all encumbrances and liens having priority over the first
      lien of the Mortgage except for liens for real estate taxes and special

      or as a result of any federal, state or local law, regulation or ordinance
      relating to hazardous wastes or hazardous substances, and, if the related
      Mortgaged Property is a condominium unit, any lien for common charges
      permitted by statute or homeowners association fees; and if the Mortgaged
      Property consists of shares of a cooperative housing corporation, any lien
      for amounts due to the cooperative housing corporation for unpaid
      assessments or charges or any lien of any assignment of rents or
      maintenance expenses secured by the real property owned by the cooperative
      housing corporation; and any security agreement, chattel mortgage or
      equivalent document related to, and delivered to the Trustee or to the
      Custodian with, any Mortgage establishes in the Seller a valid and
      subsisting first lien on the property described therein and the Seller has
      full right to sell and assign the same to the Trustee;

      the Mortgage in whole or in part, released the Mortgaged Property in whole
      or in part from the lien of the Mortgage, or executed any instrument of

      remains unpaid; and the Seller has not advanced funds, or received any
      advance of funds by a party other than the Mortgagor, directly or
      indirectly (except pursuant to any Subsidy Loan arrangement) for the
      payment of any amount required by the Mortgage, except for interest

      thirty days the first Due Date under the related Mortgage Note;

      earthquake, earth movement other than earthquake, windstorm, flood,

      that this warranty shall be deemed not to have been made at the time of
      the initial issuance of the Certificates if a title policy affording, in
      substance, the same protection afforded by this warranty is furnished to
      the Trustee by the Seller;

               (viii) Except for Mortgage Loans secured by Co-op Shares and

      accordance with its terms, except as such enforcement may be limited by
      bankruptcy, insolvency, reorganization or other similar laws affecting the
      enforcement of creditors' rights generally and by general equity
      principles (regardless of whether such enforcement is considered in a
      proceeding in equity or at law); and, to the best of the Seller's
      knowledge, all parties to the Mortgage Note and the Mortgage had legal

      Association mortgagee title insurance policy or other generally acceptable
      form of policy or insurance acceptable to Fannie Mae or Freddie Mac,
      issued by a title insurer acceptable to Fannie Mae or Freddie Mac insuring
      the originator, its successors and assigns, as to the first priority lien

      subject only to (A) 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 of such Mortgage acceptable to mortgage
      lending institutions in the area in which the Mortgaged Property is
      located or specifically referred to in the appraisal performed in
      connection with the origination of the related Mortgage Loan, (C) liens

      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 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 Trustee, no
      claims have been made under such mortgagee title insurance policy, and no
      prior holder of the related Mortgage, including the Seller, has done, by
      act or omission, anything which would impair the coverage of such
      mortgagee title insurance policy;

               (xvi) The Mortgaged Property securing each Mortgage Loan is
      insured by an insurer acceptable to Fannie Mae or Freddie Mac 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 Trustee 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 Fannie Mae or Freddie Mac
      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 Trustee and shall inure to the benefit of the Trustee
notwithstanding any restrictive or qualified endorsement or assignment.

            (c) Upon discovery by either the Seller, the Master Servicer, the
Trustee 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 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 Trustee 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, has executed and delivered to or upon the order of the Seller, in
exchange for the Mortgage Loans together with all other assets included in the
definition of "Trust Estate," receipt of which is hereby acknowledged,
Certificates in authorized denominations which evidence ownership of the entire
Trust Estate.

            SECTION 2.05      DESIGNATION OF CERTIFICATES; DESIGNATION OF
STARTUP DAY AND LATEST POSSIBLE MATURITY DATE.

            The Seller hereby designates the Classes of Class A Certificates
(other than the Class A-R Certificate) and the Classes of Class B Certificates
as classes of "regular interests" and the Class A-R Certificate as the single
class of "residual interest" in the REMIC for the purposes of Code Sections
860G(a)(1) and 860G(a)(2), respectively. The Closing Date is hereby designated
as the "Startup Day" of the REMIC within the meaning of Code Section 860G(a)(9).
The "latest possible maturity date" of the regular interests in the REMIC is
November 25, 2030 for purposes of Code Section 860G(a)(1).

            SECTION 2.06      OPTIONAL SUBSTITUTION OF MORTGAGE LOANS.

            During the three-month period beginning on the Startup Date, the
Seller shall have the right, but not the obligation, in its sole discretion for
any reason, to substitute for any Mortgage Loan a Substitute Mortgage Loan
meeting the requirements of Section 2.02. Any such substitution shall be carried
out in the manner described in Section 2.02. 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.

                                   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, 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 Trustee, 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
the Trust Estate 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 Trustee or any Servicer
      for Periodic Advances made by the Master Servicer or the Trustee 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
      Trustee 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 Trustee
      (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 TRUSTEE.

            (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 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 Trustee shall, to the extent required by Section 8.15, make such
Periodic Advance to the extent provided hereby, provided that the Trustee has
previously received the certificate of the Master Servicer described in the
following sentence. The Master Servicer shall certify to the Trustee 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
Trustee or Master Servicer is required to advance hereunder and (iv) whether the
Master Servicer has determined that it reasonably believes that such Periodic
Advance is a Nonrecoverable Advance. Amounts advanced by the Trustee or Master
Servicer shall be deposited in the Certificate Account on the related
Distribution Date. Notwithstanding the foregoing, neither the Master Servicer
nor the Trustee will be obligated to make a Periodic Advance that it reasonably
believes to be a Nonrecoverable Advance. The Trustee 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 Trustee that such failure has occurred.
Upon receipt of such certification, the Trustee shall advance such funds and
take such steps as are necessary to pay such taxes or insurance premiums.

            (c) The Master Servicer and the Trustee 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 Trustee 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 Trustee, withdraw
from the Certificate Account and remit to the Trustee any amounts to which the
Trustee 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 Trustee 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      TRUSTEE 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 Trustee 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 Trustee. The
Trustee 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 Trustee and the Trustee 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
Trustee 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 Trustee 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 Trustee to the Master Servicer
or such Servicer, as appropriate.

            Upon written certification of the Master Servicer or the Servicer
pursuant to clause (ii) of the preceding paragraph, the Trustee 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 Trustee
and a statement as to the reason such documents or pleadings are required and
that the execution and delivery thereof by the Trustee will not invalidate or
otherwise affect the lien of the Mortgage, except for the termination of such a
lien upon completion of the foreclosure proceeding or trustee's sale.

            SECTION 3.05      REPORTS TO THE TRUSTEE; ANNUAL COMPLIANCE
STATEMENTS.

            (a) Not later than 15 days after each Distribution Date, the Master
Servicer shall deliver to the Trustee 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 Fannie Mae 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 Trustee to any Certificateholder upon written
request, provided such statement is delivered, or caused to be delivered, by the
Master Servicer to the Trustee.

            (b) The Master Servicer shall deliver to the Trustee 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 Trustee to any
Certificateholder upon written request provided such certificate is delivered,
or caused to be delivered, by the Master Servicer to the Trustee.

            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 a REO Mortgage Loan, the Trustee 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 Trustee shall have no further responsibility with regard to such
Owner Mortgage Loan File or Servicer Mortgage Loan File. Neither the Trustee,
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 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 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 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 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, the
Trustee 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, or the Trustee, 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 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 Trust Estate of REMIC status
for federal income tax purposes or (iii) the imposition of any Prohibited
Transaction Tax or any federal taxes on the 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 Trustee 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 Trustee 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 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 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 Trustee the
certification required by Section 3.04 and the Trustee 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 Trustee 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
Trustee shall have no further responsibility with regard to such Owner Mortgage
Loan File or Servicer Mortgage Loan File. Neither the Trustee, the Master
Servicer nor any Servicer, acting on behalf of the Trustee, shall provide
financing from the Trust Estate to any purchaser of a Mortgage Loan.

            The Master Servicer, on behalf of the Trustee, 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 REMIC.

            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 acknowledgement 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) 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 Trustee
is obligated to make an advance pursuant to Section 3.03 and (ii) the Trustee
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 Trustee shall terminate the WFHM Servicing Agreement without the
recommendation of the Master Servicer. 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 attorneys' fees)
arising out of, or assessed against the Trustee in connection with termination
of such Servicing Agreement at the direction of the Master Servicer. 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 Master Servicer and any 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 B-1, Class B-2 and Class B-3 Certificates pursuant to the Securities
Exchange Act of 1934, as amended.

      distributable to the Class B-3 Certificates hereunder used to pay the

            sixteenth, to the Class B-4 Certificates in an amount up to the

      twenty-second will be reduced by the amount, if any, that would have been
      distributable to the Class B-6 Certificates hereunder used to pay the
      Class A-PO Deferred Amount as provided in Paragraph fourth above; and

            twenty-third, to the Holder of the Class A-R Certificate, any
      amounts remaining in the Payment Account.

            Notwithstanding the foregoing, after the Principal Balance of any
Class (other than the Class A-R Certificate) has been reduced to zero, such
Class will be entitled to no further distributions of principal or interest
(including, without limitation, any Unpaid Interest Shortfalls).

            With respect to any Distribution Date, the amount of the Principal
Adjustment, if any, attributable to any Class B Certificates will be allocated
to the Classes of Class A Certificates (other than the Class A-PO Certificates)
and any Class of Class B Certificates with a lower numerical designation pro
rata based on their outstanding Principal Balances.

            (b) On each Distribution Date prior to the Cross-Over Date, the
Class A Non-PO Principal Distribution Amount will be allocated and distributed
in reduction of the Principal Balances of the Class A Certificates (other than
the Principal Balance of the Class A-PO Certificates) in accordance with the
following priorities:

            first, to the Class A-R Certificate, until the Principal Balance
      thereof has been reduced to zero;

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

            third, to the Class A-2 Certificates, until the Principal Balance
      thereof has been reduced to zero.

            (c) Notwithstanding the foregoing, on each Distribution Date
occurring on or subsequent to the Cross-Over Date, the Class A Non-PO Principal
Distribution Amount shall be distributed among the Class A Certificates (other
than the Class 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).

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

                  (A) if the Current Class B-1 Fractional Interest is less than
            the Original Class B-1 Fractional Interest and the Class B-1
            Principal Balance is greater than zero, the Class B-2, Class B-3,
            Class B-4, Class B-5 and Class B-6 Certificates shall not be
            eligible to receive distributions of principal; or

                  (B) if the Current Class B-2 Fractional Interest is less than
            the Original Class B-2 Fractional Interest and the Class B-2
            Principal Balance is greater than zero, the Class B-3, Class B-4,
            Class B-5 and Class B-6 Certificates shall not be eligible to
            receive distributions of principal; or

                  (C) if the Current Class B-3 Fractional Interest is less than
            the Original Class B-3 Fractional Interest and the Class B-3
            Principal Balance is greater than zero, the Class B-4, Class B-5 and
            Class B-6 Certificates shall not be eligible to receive
            distributions of principal; or

                  (D) if the Current Class B-4 Fractional Interest is less than
            the Original Class B-4 Fractional Interest and the Class B-4
            Principal Balance is greater than zero, the Class B-5 and Class B-6
            Certificates shall not be eligible to receive distributions of
            principal; or

                  (E) if the Current Class B-5 Fractional Interest is less than
            the Original Class B-5 Fractional Interest and the Class B-5
            Principal Balance is greater than zero, the Class B-6 Certificates
            shall not be eligible to receive distributions of principal.

               (ii) Notwithstanding the foregoing, if on any Distribution Date
the aggregate distributions to Holders of the Classes of Class B Certificates
entitled to receive distributions of principal would reduce the Principal
Balances of the Classes of Class B Certificates entitled to receive
distributions of principal below zero, first the Class B Prepayment Percentage
of any affected Class of Class B Certificates for such Distribution Date
beginning with the affected Class with the lowest numerical Class designation
and then, if necessary, the Class B Percentage 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 Class B Prepayment Percentages and the Class B
Percentages of the remaining Classes of Class B Certificates will be recomputed
substituting for the Subordinated Prepayment Percentage and Subordinated
Percentage in such computations the difference between (A) the Subordinated
Prepayment Percentage or 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
to zero; provided, however, that if the Principal Balances of all the Classes of
Class B Certificates eligible to receive distributions of principal shall be
reduced to zero on such Distribution Date, the Class B Prepayment Percentage and
the Class B Percentage of the Class of Class B Certificates 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 Subordinated Prepayment Percentage for such Distribution Date
minus the sum of the Class B Prepayment Percentages of the Classes of Class B
Certificates having lower numerical Class designations, if any, and the
remainder of the Subordinated Percentage for such Distribution Date minus the
sum of the Class B Percentages of the Classes of Class B Certificates 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 Class B Percentage or Class B Prepayment Percentage.

            (e) 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 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(e) 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
11.23, 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 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 Class A Distribution Amount with respect to each Class of Class A
Certificates and the Class B Distribution Amount with respect to each Class of
Class B Certificates.

            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 A-R Certificate) or the Principal Balance of any Class of
Class B Certificates 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 Trustee. The Trustee 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 Trustee 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).

            (f) 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(f) 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).

            SECTION 4.02      ALLOCATION OF REALIZED LOSSES.

            (a) With respect to any Distribution Date, the principal portion of
Realized Losses (other than Debt Service Reductions, Excess Special Hazard
Losses, Excess Fraud Losses and Excess Bankruptcy Losses) will be allocated as
follows:

      first, to the Class B-6 Certificates until the Class B-6 Principal Balance
      has been reduced to zero;

      second, to the Class B-5 Certificates until the Class B-5 Principal
      Balance has been reduced to zero;

      third, to the Class B-4 Certificates until the Class B-4 Principal Balance
      has been reduced to zero;

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

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

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

      seventh, concurrently, to the Class A Certificates (other than the Class
      A-PO Certificates) and Class A-PO Certificates, pro rata, based on the
      Non-PO Fraction and the PO Fraction, respectively.

            This allocation of Realized Losses will be effected through the
reduction of the applicable Class's Principal Balance.

            (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 Mortgage Loan allocable to the Class A-PO
Certificates will equal the product of the amount of any such principal loss and
the PO Fraction for such Mortgage Loan. The principal portion of any Excess
Special Hazard Losses, Excess Fraud Losses and Excess Bankruptcy Losses
remaining after allocation to the Class A-PO Certificates in accordance with the
preceding sentence shall be allocated pro rata among the Class A Certificates
(other than the Class A-PO Certificates) and Class B Certificates based on the
Class A Non-PO Principal Balance and the Class B Principal Balance,
respectively. Any such loss allocated to the Class A Certificates shall be
allocated on the subsequent Determination Date to the outstanding Classes of
Class A Certificates (other than the Class A-PO Certificates) in accordance with
the Class A Loss Percentages as of such Determination Date. Any such loss
allocated to the Class B Certificates shall be allocated pro rata among the
outstanding Classes of Class B Certificates based on their Principal Balances.

            (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
allocated among the Certificates of such Class based on their Percentage
Interests.

            (d)   [Intentionally Left Blank]

            (e) The interest portion of Excess Special Hazard Losses, Excess
Fraud Losses and Excess Bankruptcy Losses shall be allocated between (i) the
Class A Certificates and (ii) the Class B Certificates, pro rata based on the
Class A Interest Accrual Amount and the Class B Interest Accrual Amount for the
related Distribution Date, without regard to any reduction pursuant to this
sentence. Any such loss allocated to the Class A Certificates shall be allocated
among the outstanding Classes of Class A Certificates based on each Class's
Class A Interest Percentage. Any such loss allocated to the Class B Certificates
will be allocated among the outstanding Classes of Class B Certificates based on
their Class B Interest Percentages. In addition, after the Class B Principal
Balance has been reduced to zero, the interest portion of Realized Losses (other
than Excess Special Hazard Losses, Excess Fraud Losses and Excess Bankruptcy
Losses) will be allocated among the outstanding Classes of Class A Certificates
based on their Class A Interest Percentages.

            (f) Realized Losses allocated in accordance with this Section 4.02
will be allocated as follows: (i) Liquidated Loan Losses on Liquidated Loans for
which the Liquidation Proceeds were received during, and Bankruptcy Losses
incurred in a period corresponding to, an Unscheduled Principal Receipt Period
for Full Unscheduled Principal Receipts that is a Mid-Month Receipt Period will
be allocated on the Determination Date in the month following the month in which
such Mid-Month Receipt Period ended and (ii) Liquidated Loan Losses on
Liquidated Loans for which the Liquidation Proceeds were received during, and
Bankruptcy Losses incurred in a period corresponding to, an Unscheduled
Principal Receipt Period for Full Unscheduled Principal Receipts that is a Prior
Month Receipt Period will be allocated on the Determination Date in the second
month following the month which is such Prior Month Receipt Period.

            SECTION 4.03      PAYING AGENT.

            (a) The Master Servicer hereby appoints the Trustee as initial
Paying Agent to make distributions to Certificateholders and to forward to
Certificateholders the periodic statements and the annual statements required by
Section 4.04 as agent of the Master Servicer.

            The Master Servicer may, at any time, remove or replace the Paying
Agent.

            The Master Servicer shall cause any Paying Agent that is not the
Trustee to execute and deliver to the Trustee an instrument in which such Paying
Agent agrees with the Trustee that such Paying Agent shall:

               (i)hold all amounts remitted to it by the Master Servicer for
      distribution to Certificateholders in trust for the benefit of
      Certificateholders until such amounts are distributed to
      Certificateholders or otherwise disposed of as herein provided;

               (ii)     give the  Trustee  notice of any default by the Master
      Servicer in remitting any required amount; and

               (iii) at any time during the continuance of any such default,
      upon the written request of the Trustee, forthwith pay to the Trustee all
      amounts held in trust by such Paying Agent.

            (b) The Paying Agent shall establish and maintain a Payment
Account, which shall be a separate trust account and an Eligible Account, in
which the Master Servicer shall cause to be deposited from funds in the
Certificate Account or, to the extent required hereunder, from its own funds (i)
at or before 10:00 a.m., New York time, on the Business Day preceding each
Distribution Date, by wire transfer of immediately available funds, any Periodic
Advance for such Distribution Date, pursuant to Section 3.03 and (ii) at or
before 10:00 a.m., New York time, on the Business Day preceding each
Distribution Date, by wire transfer of immediately available funds, an amount
equal to the Pool Distribution Amount. The Master Servicer may cause the Paying
Agent to invest the funds in the Payment Account. Any such investment shall be
in Eligible Investments, which shall mature not later than the Business Day
preceding the related Distribution Date (unless the Eligible Investments are
obligations of the Trustee, in which case such Eligible Investments shall mature
not later than the Distribution Date), and shall not be sold or disposed of
prior to maturity. All income and gain realized from any such investment shall
be for the benefit of the Master Servicer and shall be subject 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 Account
that was not required to be deposited therein and may clear and terminate the
Payment Account pursuant to Section 9.01.

            SECTION 4.04      STATEMENTS TO CERTIFICATEHOLDERS; REPORTS TO
THE TRUSTEE AND THE SELLER.

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      CALCULATION OF AMOUNTS; BINDING EFFECT OF
INTERPRETATIONS AND ACTIONS OF MASTER SERVICER.

            The Master Servicer will compute the amount of all distributions to
be made on the Certificates and all losses to be allocated to the Certificates.
In the event that the Master Servicer concludes that any ambiguity or
uncertainty exists in any provisions of this Agreement relating to distributions
to be made on the Certificates, the allocation of losses to the Certificates or
otherwise, the interpretation of such provisions and any actions taken by the
Master Servicer in good faith to implement such interpretation shall be binding
upon Certificateholders.

                                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-R,
Class B-4, Class B-5 and Class B-6 Certificates, integral multiples of $1,000 in
excess thereof (except, if necessary, for one Certificate of each Class (other
than the Class A-R, Class B-4, Class B-5 and Class B-6 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), and shall be substantially in the
respective forms set forth as Exhibits A-1, A-2, A-PO, A-R, B-1, B-2, B-3, B-4,
B-5, B-6 and C (reverse side of Certificates) hereto. On original issue the
Certificates shall be executed and delivered by the Trustee to or upon the order
of the Seller upon receipt by the Trustee or the Custodian of the documents
specified in Section 2.01. The aggregate principal portion 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 Trustee by any Responsible
Officer thereof. Certificates bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Trustee shall bind
the Trustee 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 Trustee,
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 Trustee 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 Trustee at the Corporate Trust Office.

            SECTION 5.02      REGISTRATION OF CERTIFICATES.

            (a)   The Trustee 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 Trustee shall provide for the registration of Certificates and of
transfers and exchanges of Certificates as herein provided. The Trustee 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 Trustee 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 Trustee 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 Trustee) 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 Trustee 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 Trustee or the Authenticating Agent
in accordance with their standard procedures.

            (b)   No transfer of a Class B-4, Class B-5 or Class 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 Trustee 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 B-4, Class B-5 or
Class B-6 Certificateholder to deliver a written Opinion of Counsel acceptable
to and in form and substance satisfactory to the Trustee 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 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 Trustee the facts surrounding such transfer,
which investment letter shall not be an expense of the Trustee, the Seller or
the Master Servicer. The Holder of a Class B-4, Class B-5 or Class B-6
Certificate desiring to effect such transfer shall, and does hereby agree to,
indemnify 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 Trustee is under an obligation to
register the Class B-4, Class B-5 or Class B-6 Certificates under said Act or
any other securities law.

            (c) No transfer of a Class B Certificate shall be made unless the
Trustee and the Seller shall have received (i) a representation letter from the
transferee in the form of Exhibit J hereto, in the case of a Class B-4, Class
B-5 or Class B-6 Certificate, or in the form of Exhibit K hereto, in the case of
a Class B-1, Class B-2 or Class 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 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 Certificate is
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 Trustee 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 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 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 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 A-R 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 A-R
Certificate in connection with the conduct of a trade or business within the
United States and has furnished the transferor and the Trustee 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 Trustee an opinion of a nationally
recognized tax counsel to the effect that the transfer of the Class A-R
Certificate to it is in accordance with the requirements of the Code and the
regulations promulgated thereunder and that such transfer of the Class A-R
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 Trustee shall not execute, and shall not
authenticate (or cause the Authenticating Agent to authenticate) and deliver, a
new Class A-R 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 Trustee shall accept a surrender for transfer or
registration of transfer, or register the transfer of, the Class A-R
Certificate, unless the transferor shall have provided to the Trustee 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 A-R 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
A-R 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 A-R 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 A-R Certificate 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 A-R 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 A-R
Certificate in constructive trust for the last transferor who was not a
disqualified organization or agent thereof, and such transferor shall be
restored as the owner of such Class A-R 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 A-R Certificate, and (ii) the Master Servicer agrees to furnish to the
Internal Revenue Service and to any transferor of the Class A-R 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 A-R 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 Trustee or
the Authenticating Agent, or the Trustee 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 Trustee 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 Trustee or the Authenticating
Agent that such Certificate has been acquired by a bona fide purchaser, the
Trustee 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 Trustee 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 Trustee 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 Certificate
Registrar and any agent of the Seller, the Master Servicer, the Trustee 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 Certificate
Registrar nor any agent of the Seller, the Master Servicer, the Trustee 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 Trustee is not acting as Certificate Registrar, the
Certificate Registrar shall furnish or cause to be furnished to the Trustee,
within 15 days after receipt by the Certificate Registrar of a request by the
Trustee in writing, a list, in such form as the Trustee 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 Trustee, 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 Trustee 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
Trustee. 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 Trustee is not the Certificate
Registrar, the Trustee 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 and the Trustee that neither the Seller, the Master Servicer, the
Certificate Registrar 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 Trustee 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 Trustee 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 Trustee 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 Trustee 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
Trustee 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, the Trustee 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 Trustee 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 Trustee 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 nor the Trustee
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 Trustee 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 Fannie Mae or Freddie Mac.

            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 Section 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 in reduction
of distributions on the Class A Certificates 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. No
such resignation shall become effective until the Trustee 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 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 (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 Fannie Mae or Freddie Mac,
is satisfactory to the Trustee, in the exercise of its reasonable judgment, and
executes and delivers to the Trustee an agreement, in form and substance
reasonably satisfactory to the Trustee, 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; 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 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 AND SELLER BY MASTER
SERVICER.

            The Master Servicer shall indemnify and hold harmless the Trustee
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 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.

            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

      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 Fannie Mae and Freddie Mac, 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 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 Trustee pursuant
to and under this Section, subject to the provisions of Section 7.05; and,
without limitation, the Trustee is hereby authorized and empowered to execute
and deliver, on behalf of the Master Servicer, as attorney-in-fact or otherwise,
any and all documents and other instruments, and to do or accomplish all other
acts or things necessary or appropriate to effect the purposes of such notice of
termination, whether to complete the transfer and endorsement or assignment of
the Mortgage Loans and related documents or otherwise. The Master Servicer
agrees to cooperate with the Trustee in effecting the termination of the Master
Servicer's 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 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 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 may, but need not if the Trustee 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, the Trustee 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      TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR.

            When the Master Servicer receives notice of termination pursuant to
Section 7.01 or the Trustee receives the resignation of the Master Servicer
evidenced by an Opinion of Counsel pursuant to Section 6.04, 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 Trustee is succeeding to the Master
Servicer as the Master Servicer, as compensation therefor, the Trustee 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
Trustee 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 Trustee 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
Trustee 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
Trustee is required to solicit bids as provided above, the Trustee 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 Trustee 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 Trustee 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 Trustee 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 Trustee to the Master Servicer at the time of such sale, transfer and
assignment to the Master Servicer's successor. The Trustee 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
Trustee and any successor servicer in effecting the termination of the Master
Servicer's servicing responsibilities and rights hereunder and shall promptly
provide the Trustee 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
Trustee 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 Trustee nor any other successor master servicer
shall be deemed to be in default hereunder by reason of any failure to make, or
any delay in making, any distribution hereunder or any portion thereof 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 Trustee) 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) by any 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 Trustee shall
give prompt written notice thereof to Certificateholders at their respective
addresses appearing in the Certificate Register. The Trustee shall also, within
45 days after the occurrence of any Event of Default known to the Trustee, 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.

            The Trustee, 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, 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, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee, 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 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 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 shall be determined solely by the express
      provisions of this Agreement, the Trustee 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, in the absence of bad faith
      on the part of the Trustee, the Trustee may conclusively rely, as to the
      truth of the statements and the correctness of the opinions expressed
      therein, upon any certificates or opinions furnished to the Trustee, and
      conforming to the requirements of this Agreement;

               (ii) The Trustee 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, or exercising any
      trust or power conferred upon the Trustee, under this Agreement; and

               (iii) The Trustee shall not be liable for any error of judgment
      made in good faith by any of its Responsible Officers, unless it shall be
      proved that the Trustee 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 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.

            Except as otherwise provided in Section 8.01:

               (i) The Trustee 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 may
      prescribe;

               (ii) The Trustee 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) The Trustee shall not 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 Trustee 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
      Trustee may be required to act as Master Servicer pursuant to Section 7.05
      and thereupon only for the acts or omissions of the Trustee as successor
      Master Servicer; and

               (v) The Trustee 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      TRUSTEE NOT 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, the Trustee 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 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, not reasonably assured to the
Trustee by the security afforded to it by the terms of this Agreement, the
Trustee 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 shall be repaid
by the Master Servicer upon demand.

            SECTION 8.04      TRUSTEE NOT 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 the Trustee assumes no responsibility as to the
correctness of the same. The Trustee makes no representation for the correctness
of the same. The Trustee makes no 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, the Trustee 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 MAY OWN CERTIFICATES.

            The Trustee, 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 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 the Trustee from
time to time, and the Trustee 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 and the
Master Servicer will pay or reimburse the Trustee 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.

            The Trustee 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 none 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 shall cease to be eligible in accordance with the
provisions of this Section, the Trustee shall resign immediately in the manner
and with the effect specified in Section 8.08.

            SECTION 8.08      RESIGNATION AND REMOVAL.

            The Trustee 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.
Upon receiving such notice of resignation, the Master Servicer shall promptly
appoint a successor trustee 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 shall have been appointed and have accepted
appointment within 30 days after the giving of such notice of resignation, the
resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor trustee.

            If at any time the Trustee 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 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 of the property or
affairs of the Trustee 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 appoint a successor trustee by written instrument,
in duplicate, one copy of which instrument shall be delivered to the Trustee so
removed and one copy to the successor trustee.

            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 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 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 appointed as provided in Section 8.08 shall
execute, acknowledge and deliver to the Master Servicer and to its predecessor
trustee an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the predecessor trustee 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
herein. The predecessor trustee 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 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
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, the successor trustee shall
cause such notice to be mailed at the expense of the Master Servicer.

            SECTION 8.10      MERGER OR CONSOLIDATION.

            Any Person into which the Trustee 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 shall be a party, or any Person succeeding to the business of such
entity, shall be the successor of the Trustee 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 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 the REMIC to federal, state or local tax or cause the REMIC to fail
to qualify as a REMIC, which Opinion of Counsel shall be at the sole expense of
the Trustee.

            SECTION 8.11      AUTHENTICATING AGENT.

            The Trustee may appoint an Authenticating Agent, which shall be
authorized to act on behalf of the Trustee in authenticating Certificates.
Wherever reference is made in this Agreement to the authentication of
Certificates by the Trustee or the Trustee's countersignature, such reference
shall be deemed to include authentication on behalf of the Trustee by the
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee 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 Trustee
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 Seller and
the Master Servicer. The Trustee 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 Trustee 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 Trustee. 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 Trustee 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 Trustee,
by entering into a Custodial Agreement. Subject to this Article VIII, the
Trustee 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 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 a REMIC;
or (ii) cause the imposition of any federal, state or local income, prohibited
transaction, contribution or other tax on either the 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 Trustee, the Trustee, 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 using a calendar year as the taxable year for the REMIC and the accrual
method of accounting; (ii) in the first such federal tax return, make, or cause
to be made, elections satisfying the requirements of the REMIC Provisions, on
behalf of the Trust Estate, to treat the Trust Estate 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 REMIC, 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 Trustee 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 Form
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 REMIC,
including but not limited to the income, expenses, individual Mortgage Loans
(including REO Mortgage Loans), other assets and liabilities of the REMIC, and
the fair market value and adjusted basis of the REMIC property 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 the REMIC within the meaning of Code
Section 860D(a)(2) other than the interests represented by the Class A-1, Class
A-2, Class A-PO, Class A-R, Class B-1, Class B-2, Class B-3, Class B-4, Class
B-5 and Class B-6 Certificates; (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 Trust Estate or the REMIC to tax or (c) cause the
Trust Estate to fail to qualify as a REMIC; (ix) exercise reasonable care not to
allow the 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 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 REMIC, 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 REMIC within the meaning of Treasury Regulations Section
1.860F-4(d), and the Master Servicer is hereby designated as agent of the Class
A-R Certificateholder for such purpose (or if the Master Servicer is not so
permitted, the Holder of the Class A-R Certificate shall be the tax matters
person 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 shall sign the tax returns referred to in clause (i) of
the second preceding sentence.

            In order to enable the Master Servicer 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 or the
Trustee, as the case may be, promptly upon request therefor, any such additional
information or data that the Master Servicer 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
or the Trustee, as the case may be, for any losses, liabilities, damages, claims
or expenses of the Master Servicer or the Trustee arising from any errors or
miscalculations by the Master Servicer 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 or the Trustee, as
the case may be, on a timely basis. The Master Servicer hereby indemnifies the
Seller and the Trustee for any losses, liabilities, damages, claims or expenses
of the Seller 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 REMIC as described above. In the event that
the Trustee prepares any of the federal, state and local tax returns of the
REMIC as described above, the Trustee hereby indemnifies the Seller and the
Master Servicer for any losses, liabilities, damages, claims or expenses of the
Seller or the Master Servicer arising from the Trustee'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 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 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 Trustee shall make a Periodic Advance as required by Section 3.03
hereof; provided, however, the Trustee 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 Trustee 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.

                                   ARTICLE IX

                                   TERMINATION

            SECTION 9.01      TERMINATION UPON PURCHASE BY THE SELLER OR
LIQUIDATION OF ALL MORTGAGE LOANS.

            Subject to Section 9.02, the respective obligations and
responsibilities of the Seller, the Master Servicer and the Trustee created
hereby (other than the obligation of the Trustee to make certain payments after
the Final Distribution Date to Certificateholders and the obligation of the
Master Servicer to send certain notices as hereinafter set forth and the tax
reporting obligations under Sections 4.05 and 8.14 hereof) shall terminate upon
the last action required to be taken by the Trustee on the Final Distribution
Date pursuant to this Article IX following the earlier of (i) the purchase by
the Seller of all Mortgage Loans and all property acquired in respect of any
Mortgage Loan remaining in the Trust Estate at a price equal to the sum of (x)
100% of the unpaid principal balance of each Mortgage Loan (other than any REO
Mortgage Loan) as of the Final Distribution Date, and (y) the fair market value
of the Mortgaged Property related to any REO Mortgage Loan (as determined by the
Master Servicer as of the close of business on the third Business Day next
preceding the date upon which notice of any such termination is furnished to
Certificateholders pursuant to the third paragraph of this Section 9.01), plus
any accrued and unpaid interest through the last day of the month preceding the
month of such purchase at the applicable Mortgage Interest Rate less any Fixed
Retained Yield on each Mortgage Loan (including any REO Mortgage Loan) and (ii)
the final payment or other liquidation (or any advance with respect thereto) of
the last Mortgage Loan remaining in the Trust Estate (including for this purpose
the discharge of any Mortgagor under a defaulted Mortgage Loan on which a
Servicer is not obligated to foreclose due to environmental impairment) or the
disposition of all property 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 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
hereof.

            The right of the Seller to purchase all the assets of the Trust
Estate pursuant to clause (i) of the preceding paragraph are subject to Section
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 11.22. In the case of any purchase by the Seller pursuant to said clause
(i), the Seller shall provide to the Trustee the certification required by
Section 3.04 and the Trustee 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 Trustee for
payment of the final distribution and cancellation, shall be given promptly by
the Trustee 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 Trustee 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
Trustee therein specified. If the Seller is exercising its right to purchase,
the Seller 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 Trustee
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 A-R Certificate, the amounts, if any, which remain on deposit in
the Certificate Account (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. 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 Trustee 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 Section 4.02(a) 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 Trustee 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. The Trustee shall give a second written
notice to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
three months after the second notice all the Certificates shall not have been
surrendered for cancellation, the Trustee may take appropriate steps, or may
appoint an agent to take appropriate steps, to contact the remaining
Certificateholders concerning surrender of their Certificates, and the cost
thereof shall be paid out of the funds 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 Trustee 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 the REMIC to federal tax or cause the
Trust Estate to fail to qualify as a REMIC 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 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 return of the 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 Trustee
      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 and the Trustee, 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 a REMIC 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 or
the REMIC pursuant to the Code that would be a claim against the Trust Estate,
provided that (a) the Trustee has 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 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 Trust Estate
or the 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.

            This Agreement or any Custodial Agreement may also be amended from
time to time by the Seller, the Master Servicer and the Trustee 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, the
Trustee shall not 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 the REMIC to tax or cause the Trust Estate 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 Trustee 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 Trustee 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 or the Trustee; provided, however, (i) that
cuch 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 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 Trustee.

            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 Trustee,
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 Trustee 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 Trustee
to institute such action, suit or proceeding in its own name as Trustee
hereunder and shall have offered to the Trustee such reasonable indemnity as it
may require against the cost, expenses and liabilities to be incurred therein or
thereby, and the Trustee, for 60 days after its receipt of such notice, request
and offer of indemnity, shall have neglected or refused to institute any such
action, suit or proceeding; it being understood and intended, and being
expressly covenanted by each Certificateholder with every other
Certificateholder and the Trustee, that no one or more Holders of Certificates
shall have any right in any manner whatever by virtue or by availing 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 Trustee 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
writing and shall be deemed to have been duly given if personally delivered at
or mailed by certified or registered mail, return receipt requested (i) in the
case of the Seller, to Wells Fargo Asset Securities Corporation, 7485 New

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

Shortfall and the interest portion of certain Realized Losses allocated to the
Class A-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
Principal Balance of this Certificate will be made after due notice of the
pendency of such distribution and only upon presentation and surrender of this
Certificate at the office or agency specified by the Trustee for that purpose in
the notice of final distribution.

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

            This Certificate constitutes a "regular interest" in a "real estate
mortgage investment conduit" as those terms are defined in Section 860G(a)(1)
and Section 860D, respectively, of the Internal Revenue Code of 1986, as

            Unless this Certificate has been countersigned by an authorized
officer of the Trustee, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

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

satisfactory to the Trustee and the Seller that such transfer is exempt
(describing the applicable exemption and the basis therefor) from or is being

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 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. In connection

letter, in the form as described in the Agreement, stating either (a) that 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 Trustee 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

owner of the Percentage Interest evidenced by this Certificate in monthly
distributions to the Holders of the Class B-5 Certificates with respect to a
Trust Estate consisting of a pool of fixed interest rate, conventional, monthly
pay, fully amortizing, first lien, one- to four-family residential mortgage
loans, other than the Fixed Retained Yield, if any, with respect thereto, and
which may include loans secured by shares issued by cooperative housing
corporations (the "Mortgage Loans") 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 October 30, 2000 (the
"Agreement") among the Seller, Wells Fargo Bank Minnesota, National Association,
as master servicer (the "Master Servicer") and First Union National Bank, as
trustee (the "Trustee"), a summary of certain of the pertinent provisions of
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, subject to
the prior rights of the Class A Certificates and each Class of Class B
Certificates bearing a lower numerical designation as specified in the
Agreement, any Class B-5 Distribution Amount required to be distributed to
Holders of the Class B-5 Certificates on such Distribution Date, subject to
adjustment, in certain events, as specified in the Agreement. The pass-through
rate on the Class B-5 Certificates applicable to each Distribution Date will be
7.000% per annum. 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 B-5 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.
Notwithstanding the above, the final distribution in reduction of the Principal
Balance of this Certificate will be made after due notice of the pendency of
such distribution and only upon presentation and surrender of this Certificate
at the office or agency specified by the Trustee for that purpose in the notice
of final distribution.

            No transfer of a Class B-5 Certificate will be made unless such
transfer is exempt from the registration requirements of the Securities Act of
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 Trustee or the Seller may require the
Holder to deliver an opinion of counsel acceptable to and in form and substance
satisfactory to the Trustee 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 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. In connection
with any such transfer, the Trustee 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 Trustee 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 constitutes a "regular interest" in a "real estate
mortgage investment conduit" as those terms are defined in Section 860G(a)(1)
and Section 860D, respectively, of the Internal Revenue Code of 1986, as
amended.

            Unless this Certificate has been countersigned by an authorized
officer of the Trustee, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

                                 SERIES 2000-10

            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 Trustee, such advances are reimbursable to such Servicer, the Master
Servicer or the Trustee 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 Trustee, as applicable, of advances made by such
Servicer, the Master Servicer or the Trustee.

            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 and the Trustee and the rights of the
Certificateholders under the Agreement at any time by the Seller, the Master
Servicer 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 Trustee, duly endorsed by, or
accompanied by an assignment in the form below or other written instrument of
transfer in form satisfactory to the Trustee 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 Trustee 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 Trustee and the Certificate
Registrar, and any agent of the Seller, the Master Servicer, 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 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 Trustee 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 Trustee, have
entered into a Pooling and Servicing Agreement dated as of October 30, 2000
relating to the issuance of Mortgage Pass-Through Certificates, Series 2000-10
(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 Trustee
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 Trustee, 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 Trustee 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 Trustee subsequent to the date hereof (the "Custodial Files") as
agent for the Trustee, 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 Trustee 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 Trustee.

            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 Trustee.

            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 Trustee. 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 Trustee, 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; Trustee May Remove Custodian. The
Custodian may resign from the obligations and duties hereby imposed upon it as
such obligations and duties relate to its acting as Custodian of the Mortgage
Loans. Upon receiving such notice of resignation, the Trustee shall either take
custody of the 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 Trustee 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 Trustee may remove the Custodian at any time. In such event, the
Trustee shall appoint, or petition a court of competent jurisdiction to appoint,
a successor Custodian hereunder. Any successor Custodian shall be a depository
institution subject to supervision or examination by federal or state authority
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
Trustee 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 Trustee 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 Trustee shall enter into any amendment hereof except as
permitted by the Pooling and Servicing Agreement. The Trustee 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 Trustee, 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.

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 2000-10, Class A-R
Certificate (the "Class A-R 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 A-R
Certificate as they become due.

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

            6.    That the Purchaser will not transfer the Class A-R 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 A-R
Certificate in connection with the conduct of a trade or business within the
United States and has furnished the transferor and the Trustee 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 Trustee an opinion of a nationally recognized tax
counsel to the effect that the transfer of the Class A-R Certificate to it is in
accordance with the requirements of the Code and the regulations promulgated
thereunder and that such transfer of the Class A-R 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 U.S. 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 A-R 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 REMIC pursuant to
Section 8.14 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.

Wells Fargo Asset Securities Corporation
7485 New Horizon Way
Frederick, Maryland 21703

            The undersigned (the "Purchaser") proposes to purchase Wells Fargo
Asset Securities Corporation Mortgage Pass-Through Certificates, Series 2000-10,
Class [B-4][B-5][B-6] Certificates (the "Class [B-4][B-5][B-6] 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 October 30, 2000 (the "Pooling and
Servicing Agreement") among Wells Fargo Asset Securities Corporation, as seller
(the "Seller"), Wells Fargo Bank Minnesota, National Association, as master
servicer (the "Master Servicer") and First Union National Bank, as trustee (the
"Trustee"), of Wells Fargo Asset Securities Corporation Mortgage Pass-Through
Certificates, Series 2000-10.

            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 Trustee that:

            (a)   The Purchaser is duly organized, validly existing and in good
standing under the laws of the jurisdiction in which the Purchaser is organized,
is authorized to invest in the Class [B-4][B-5][B-6] Certificates, and to enter
into this Agreement, and duly executed and delivered this Agreement.

            (b)   The Purchaser is acquiring the Class [B-4][B-5][B-6]
Certificates for its own account as principal and not with a view to the
distribution thereof, in whole or in part.

            [(c) The Purchaser has knowledge of financial and business matters
and is capable of evaluating the merits and risks of an investment in the Class
[B-4][B-5][B-6] Certificates; the Purchaser has sought such accounting, legal
and tax advice as it has considered necessary to make an informed investment
decision; and the Purchaser is able to bear the economic risk of an investment
in the Class [B-4][B-5][B-6] Certificates and can afford a complete loss of such
investment.]

            [(c)  The Purchaser is a "Qualified Institutional Buyer" within the
meaning of Rule 144A of the Act.]

            (d)   The Purchaser confirms that (a) it has received and reviewed a
copy of the Private Placement Memorandum dated __________ __, 19__, relating to
the Class [B-4][B-5][B-6] Certificates and reviewed, to the extent it deemed
appropriate, the documents attached thereto or incorporated by reference
therein, (b) it has had the opportunity to ask questions of, and receive answers
from the Seller concerning the Class [B-4][B-5][B-6] Certificates and all
matters relating thereto, and obtain any additional information (including
documents) relevant to its decision to purchase the Class [B-4][B-5][B-6]
Certificates that the Seller possesses or can possess without unreasonable
effort or expense and (c) it has undertaken its own independent analysis of the
investment in the Class [B-4][B-5][B-6] Certificates. The Purchaser will not use
or disclose any information it receives in connection with its purchase of the
Class [B-4][B-5][B-6] Certificates other than in connection with a subsequent
sale of Class [B-4][B-5][B-6] Certificates.

            (e)   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 [B-4][B-5][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 [B-4][B-5][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 Trustee 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 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).

            (f)   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 [B-4][B-5][B-6] Certificates is in compliance therewith.

            Section 3.  Transfer of Class [B-4][B-5][B-6] Certificates.

            (a)   The Purchaser understands that the Class [B-4][B-5][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 [B-4][B-5][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 Trustee
is under any obligation to register the Class [B-4][B-5][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 Trustee shall require, in order to assure compliance with such laws, that
the Certificateholder's prospective transferee certify to the Seller and the
Trustee 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 Trustee 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
Trustee, the Master Servicer or the Seller. Any such Certificateholder desiring
to effect such transfer shall, and does hereby agree to, indemnify the Trustee,
the Master Servicer, any Paying Agent acting on behalf of the Trustee 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 [B-4][B-5][B-6] Certificate shall be
made unless the transferee provides the Seller and the Trustee with a
Transferee's Letter, substantially in the form of this Agreement.

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

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

acknowledges and agrees as follows:

            Section 1. Definitions. Each capitalized term used herein and not

            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 Trustee 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 [B-1] [B-2] [B-3] 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

      Section V(a)(1) of PTE 95-60) or by the same employee organization, exceed
      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-1][B-2][B-3] Certificate 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 Trustee 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 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).

            Section 2.1.      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 2.2.      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 2.3.      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
Proceeds pursuant to the Pooling and Servicing Agreement. After making such
withdrawal, all amounts remaining in the Collateral Fund (after adjustment for
all withdrawals and deposits pursuant to subsection (c) in respect of such
Mortgage Loan shall be released to the Purchaser.

            Section 2.4.      Termination.

            (a) With respect to all Mortgage Loans included in the Trust Estate,
the Purchaser's right to make any Election to Delay Foreclosure or any Election
to Foreclose and the Company's obligations under Section 2.01 shall terminate
(i) at such time as the Principal Balance of the Class B Certificates has been
reduced to zero, (ii) if the greater of (x) 43% (or such lower or higher
percentage that represents the related Servicer's actual historical loss
experience with respect to the Mortgage Loans in the related pool as determined
by the Company) of the aggregate principal balance of all Mortgage Loans that
are in foreclosure or are more than 90 days delinquent on a contractual basis
and REO properties or (y) the aggregate amount that the Company estimates
through the normal servicing practices of the related Servicer will be required
to be withdrawn from the Collateral Fund with respect to Mortgage Loans as to
which the Purchaser has made an Election to Delay Foreclosure or an Election to
Foreclosure, exceeds (z) the then-current principal balance of the Class B
Certificates, (iii) upon any transfer by the Purchaser of any interest (other
than the minority interest therein, but only if the transferee provides written
acknowledgment to the Company of the Purchaser's right hereunder and that such
transferee will have no rights hereunder) in the Class B Certificates (whether
or not such transfer is registered under the Pooling and Servicing Agreement),
including any such transfer in connection with a termination of the Trust Estate
or (iv) upon any breach of the terms of this Agreement by the Purchaser.

            (b) Except as set forth in 2.04(a), this Agreement and the
respective rights, obligations and responsibilities of the Purchaser and the
Company hereunder shall terminate upon the later to occur of (i) the final
liquidation of the last Mortgage Loan as to which the Purchaser made any
Election to Delay Foreclosure or any Election to Foreclose and the withdrawal of
all remaining amounts in the Collateral Fund as provided herein and (ii) ten
Business Days' notice. The Purchaser's right to make an election pursuant to
Section 2.02 or Section 2.03 hereof with respect to a particular Mortgage Loan
shall terminate if the Purchaser fails to make any deposit required pursuant to
Section 2.02(d) or 2.03(b) or if the Purchaser fails to make any other deposit
to the Collateral Fund pursuant to this Agreement.

                                   ARTICLE III

                       COLLATERAL FUND; SECURITY INTEREST

            Section 3.1.      Collateral Fund.

            Upon receipt from the Purchaser of the initial amount required to be
deposited in the Collateral Fund pursuant to Article II, the Company shall
establish and maintain with Bankers Trust Company as a segregated account on its
books and records an account (the "Collateral Fund"), entitled "Wells Fargo Bank
Minnesota, National Association, as Master Servicer, for the benefit of
registered holders of Wells Fargo Asset Securities Corporation Mortgage
Pass-Through Certificates, Series 2000-10. Amounts held in the Collateral Fund
shall continue to be the property of the Purchaser, subject to the first
priority security interest granted hereunder for the benefit of the
Certificateholders, until withdrawn from the Collateral Fund pursuant to Section
2.02 or 2.03 hereof. The Collateral Fund shall be an "outside reserve fund"
within the meaning of the REMIC Provisions, beneficially owned by the Purchaser
for federal income tax purposes. All income, gain, deduction or loss with
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
the Purchaser as the beneficial owner thereof.

            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 3.2.      Collateral Fund Permitted Investments.

            The Company shall, at the written direction of the Purchaser, invest
the funds in the Collateral Fund in Collateral Fund Permitted Investments. Such
direction shall not be changed more frequently than quarterly. In the absence of
any direction, the Company shall select such investments in accordance with the
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 3.3.      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 3.4.      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.

                            MISCELLANEOUS PROVISIONS
