            Section 2.01 Conveyance of Mortgage Loans. (a) The Depositor,
concurrently with the execution and delivery hereof, hereby sells, transfers,
assigns, sets over and otherwise conveys to the Trustee on behalf of the Trust
for the benefit of the Certificateholders, without recourse, all the right,
title and interest of the Depositor in and to the Mortgage Loans, including all
interest and principal received on or with respect to the Mortgage Loans (other
than payments of principal and interest due and payable on the Mortgage Loans on

Purchase Agreement, including the rights of the Depositor as assignee of the
Seller with respect to the Seller's rights under the Servicing Agreements, and
the Depositor's rights under the BANA Servicing Agreement. The foregoing sale,
transfer, assignment and set over does not and is not intended to result in a
creation of an assumption by the Trustee of any obligation of the Depositor or
any other Person in connection with the Mortgage Loans or any agreement or
instrument relating thereto, except as specifically set forth herein. It is
agreed and understood by the parties hereto that it is not intended that any
mortgage loan be included in the Trust that is a "High-Cost Home Loan" as
defined in any of (i) the New Jersey Home Ownership Act effective November 27,
2003, (ii) the New Mexico Home Loan Protection Act effective January 1, 2004 or
(iii) the Massachusetts Predatory Home Loan Practices Act effective November 7,

has delivered or caused to be delivered to the Trustee, or a Custodian on behalf
of the Trustee, for the benefit of the Certificateholders, the following
documents or instruments with respect to each Mortgage Loan so assigned:

            (i) the original Mortgage Note, endorsed by manual or facsimile
      signature in the following form: "Pay to the order of Wachovia Bank,

      Corporation Mortgage Pass-Through Certificates, Series 2004-4, without
      recourse," with all necessary intervening endorsements showing a complete
      chain of endorsement from the originator to the Trustee (each such
      endorsement being sufficient to transfer all right, title and interest of
      the party so endorsing, as noteholder or assignee thereof, in and to that
      Mortgage Note) and, in the case of any Mortgage Loan originated in the
      State of New York documented by a NYCEMA, the NYCEMA, the new Mortgage
      Note, if applicable, the consolidated Mortgage Note and the consolidated
      Mortgage;

            (ii) except as provided below and other than with respect to the
      Mortgage Loans purchased by the Seller from Wells Fargo Bank, N.A., the
      original recorded Mortgage with evidence of a recording thereon, or if any
      such Mortgage has not been returned from the applicable recording office
      or has been lost, or if such public recording office retains the original
      recorded Mortgage, a copy of such Mortgage certified by the applicable
      Servicer (which may be part of a blanket certification) as being a true
      and correct copy of the Mortgage;

            (iii) subject to the provisos at the end of this paragraph, a duly
      executed Assignment of Mortgage to "Wachovia Bank, National Association,
      as trustee for the holders of Banc of America Funding Corporation Mortgage

      blanket assignment or assignments), together with, except as provided
      below and other than with respect to the Mortgage Loans purchased by the
      Seller from Wells Fargo Bank, N.A., originals of all interim recorded
      assignments of such mortgage or a copy of such interim assignment
      certified by the applicable Servicer (which may be part of a blanket
      certification) as being a true and complete copy of the original recorded
      intervening assignments of Mortgage (each such assignment, when duly and
      validly completed, to be in recordable form and sufficient to effect the
      assignment of and transfer to the assignee thereof, under the Mortgage to
      which the assignment relates); provided that, if the related Mortgage has
      not been returned from the applicable public recording office, such
      Assignment of Mortgage may exclude the information to be provided by the
      recording office; and provided, further, if the related Mortgage has been
      recorded in the name of Mortgage Electronic Registration Systems, 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
      WMMSC Master Servicer shall, in the case of the WMMSC Master Serviced
      Loans, or, in the case of the WF Master Serviced Loans, the WF Master
      Servicer shall enforce the obligations of the applicable WF Servicer to
      take all actions as are necessary to cause the Trust to be shown as the
      owner of the related Mortgage Loan on the records of MERS for purposes of
      the system of recording transfers of beneficial ownership of mortgages
      maintained by MERS;

            (iv) the originals of all assumption, modification, consolidation or
      extension agreements, if any, with evidence of recording thereon, if any;

      original mortgagee title insurance policy and all riders thereto; (B) a
      title search showing no lien (other than standard exceptions) on the
      Mortgaged Property senior to the lien of the Mortgage or (C) an opinion of
      counsel of the type customarily rendered in the applicable jurisdiction in
      lieu of a title insurance policy;

            (vi) the original of any guarantee executed in connection with the
      Mortgage Note;

            (vii) for each Mortgage Loan, if any, which is secured by a
      residential long-term lease, a copy of the lease with evidence of
      recording indicated thereon, or, if the lease is in the process of being
      recorded, a photocopy of the lease, certified by an officer of the
      respective prior owner of such Mortgage Loan or by the applicable title
      insurance company, closing/settlement/escrow agent or company or closing
      attorney to be a true and correct copy of the lease transmitted for
      recordation;

            (viii) the original of any security agreement, chattel mortgage or
      equivalent document executed in connection with the Mortgage; and

            (ix) for each Mortgage Loan secured by Cooperative Stock (other than
      with respect to any Mortgage Loan secured by Cooperative Stock purchased
      by the Seller from Wells Fargo Bank, N.A.), the originals of the following
      documents or instruments:

                  (A) The stock certificate;

                  (B) The stock power executed in blank;

                  (C) The executed proprietary lease;

                  (D) The executed recognition agreement;

                  (E) The executed assignment of recognition agreement, if any;

                  (F) The executed UCC-1 financing statement with evidence of
             recording thereon; and

                  (G) Executed UCC-3 financing statements or other appropriate
            UCC financing statements required by state law, evidencing a
            complete and unbroken line from the mortgagee to the Trustee with
            evidence of recording thereon (or in a form suitable for
            recordation).

provided, however, that on the Closing Date, with respect to item (iii), if an
Assignment of Mortgage is required to be recorded as set forth below, the
Depositor has delivered to the Trustee or the related Custodian on behalf of the
Trustee, as the case may be, a copy of such Assignment of Mortgage in blank
rather than in the name of the Trustee and has caused the applicable WF Servicer
(in the case of the WF Master Serviced Loans) or the WMMSC Master Servicer (in
the case of the WMMSC Master Serviced Loans) to retain the completed Assignment
of Mortgage for recording as described below, unless such Mortgage has been
recorded in the name of MERS or its designee. In addition, if the Depositor is
unable to deliver or cause the delivery of any original Mortgage Note due to the
loss of such original Mortgage Note, the Depositor may deliver a copy of such
Mortgage Note, together with a lost note affidavit, and shall thereby be deemed
to have satisfied the document delivery requirements of this Section 2.01(b).

            If in connection with any Mortgage Loans, the Depositor cannot
deliver (A) the Mortgage, (B) all interim recorded assignments, (C) all
assumption, modification, consolidation or extension agreements, if any, or (D)
the lender's title policy, if any, (together with all riders thereto), if
applicable, satisfying the requirements of clause (ii), (iii), (iv) or (v)
above, respectively, concurrently with the execution and delivery hereof because
such document or documents have not been returned from the applicable public
recording office in the case of clause (ii), (iii) or (iv) above, or because the
title policy, if applicable, has not been delivered to any of the related WF
Servicer, the WMMSC Master Servicer, the Seller or the Depositor, as applicable,
by the applicable title insurer, if any, in the case of clause (v) above, the
Depositor shall promptly deliver or cause to be delivered to the Trustee or the
related Custodian on behalf of the Trustee, as the case may be, in the case of
clause (ii), (iii) or (iv) above, such Mortgage, such interim assignment or such
assumption, modification, consolidation or extension agreement, as the case may
be, with evidence of recording indicated thereon upon receipt thereof from the
public recording office, but in no event shall any such delivery of any such
documents or instruments be made later than one year following the Closing Date,
unless, in the case of clause (ii), (iii) or (iv) above, there has been a
continuing delay at the applicable recording office or, in the case of clause
(v), there has been a continuing delay at the applicable insurer and the
Depositor has delivered the Officer's Certificate to such effect to the Trustee.
The Depositor shall forward or cause to be forwarded to the Trustee or the
applicable Custodian, on behalf of the Trustee, as the case may be, (1) from
time to time additional original documents evidencing an assumption or
modification of a Mortgage Loan and (2) any other documents required to be
delivered by the Depositor, the applicable WF Servicer (in the case of the WF
Master Serviced Loans) or the WMMSC Master Servicer (in the case of the WMMSC
Master Serviced Loans) to the Trustee or the Custodian on the Trustee's behalf,
as the case may be. In the event that the original Mortgage is not delivered and
in connection with the payment in full of the related Mortgage Loan the public
recording office requires the presentation of a "lost instruments affidavit and
indemnity" or any equivalent document, because only a copy of the Mortgage can
be delivered with the instrument of satisfaction or reconveyance, the Depositor
(in the case of the WF Master Serviced Loans) or the WMMSC Master Servicer (in
the case of the WMMSC Master Serviced Loans) shall prepare, execute and deliver
or cause to be prepared, executed and delivered, on behalf of the Trust, such a
document to the public recording office.

            Upon discovery by the Depositor or notice from Wells Fargo Bank, the
WF Master Servicer or Securities Administrator that a Document Transfer Event
has occurred, the Depositor shall, with respect to Mortgage Loans purchased by
the Seller from Wells Fargo Bank, N.A., deliver or cause to be delivered to the
Trustee or the Custodian, on behalf of the Trustee, within 60 days copies (which
may be in electronic form mutually agreed upon by the Depositor and the Trustee)
of the following additional documents or instruments to the Mortgage File with
respect to each such Mortgage Loan; provided, however, that originals of such
documents or instruments shall be delivered to the Trustee or Custodian, as
applicable, if originals are required under the law in which the related
Mortgaged Property is located in order to exercise all remedies available to the
Trust under applicable law following default by the related Mortgagor:

            (1) other than if the related Mortgage has been recorded in the name
of MERS or its designee, originals of all interim recorded assignments of such
mortgage or a copy of such interim assignments certified by the Depositor as
being a true and complete copy of the original recorded intervening assignments
of Mortgage (each such assignment, when duly and validly completed, to be in
recordable form and sufficient to effect the assignment of and transfer to the
assignee thereof, under the Mortgage to which the assignment relates);

            (2) the original or a certified copy of the lender's title insurance
policy;

             (3) the original Mortgage with evidence of recording thereon, and
the original recorded power of attorney, if the Mortgage was executed pursuant
to a power of attorney, with evidence of recording thereon or, if such Mortgage
or power of attorney has been submitted for recording but has not been returned
from the applicable public recording office, has been lost or is not otherwise
available, a copy of such Mortgage or power of attorney, as the case may be,
certified to be a true and complete copy of the original submitted for
recording; and

            (4) for each Mortgage Loan secured by Co-op Shares, the originals of
the following documents or instruments:

                  (A) The stock certificate;

                  (B) The stock power executed in blank;

                  (C) The executed proprietary lease;

                  (D) The executed recognition agreement;

                  (E) The executed assignment of recognition agreement, if any;

                  (F) The executed UCC-1 financing statement with evidence of
      recording thereon; and

                  (G) Executed UCC-3 financing statements or other appropriate
      UCC financing statements required by state law, evidencing a complete and
      unbroken line from the mortgagee to the Trustee with evidence of recording
      thereon (or in a form suitable for recordation).

            With respect to each WF Master Serviced Loan, as promptly as
practicable subsequent to such transfer and assignment, the WF Master Servicer
shall (except for any Mortgage which has been recorded in the name of MERS or
its designee) enforce the obligations of the related WF Servicer pursuant to the
related Servicing Agreement to (I) cause each Assignment of Mortgage to be in
proper form for recording in the appropriate public office for real property
records within the time period required in the applicable Servicing Agreement
and (II) at the Depositor's expense, cause to be delivered for recording in the
appropriate public office for real property records the Assignments of the
Mortgages to the Trustee, except that, with respect to any Assignment of a
Mortgage as to which the related WF Servicer has not received the information
required to prepare such assignment in recordable form, such WF Servicer's
obligation to do so and to deliver the same for such recording shall be as soon
as practicable after receipt of such information and in accordance with the
applicable Servicing Agreement.

            With respect to each WMMSC Master Serviced Loan, as promptly as
practicable subsequent to such transfer and assignment and in any event, within
30 days thereafter, the WMMSC Master Servicer shall (except for any Mortgage
which has been recorded in the name of MERS or its designee), (I) cause each
Assignment of Mortgage to be in proper form for recording in the appropriate
public office for real property records within 30 days of the Closing Date and
(II) at the Depositor's expense, cause to be delivered for recording in the
appropriate public office for real property records the Assignments of the
Mortgages to the Trustee, except that, with respect to any Assignment of a
Mortgage as to which the WMMSC Master Servicer has not received the information
required to prepare such assignment in recordable form, the WMMSC Master
Servicer's obligation to do so and to deliver the same for such recording shall
be as soon as practicable after receipt of such information and in any event
within 30 days after the receipt thereof.

            No recording of an Assignment of Mortgage will be required in a
state if either (i) the Depositor furnishes to the Trustee and the Securities
Administrator an unqualified Opinion of Counsel reasonably acceptable to the
Trustee and the Securities Administrator to the effect that recordation of such
assignment is not necessary under applicable state law to preserve the Trustee's
interest in the related Mortgage Loan against the claim of any subsequent
transferee of such Mortgage Loan or any successor to, or creditor of, the
Depositor or the originator of such Mortgage Loan or (ii) the recordation of an
Assignment of Mortgage in such state is not required by either Rating Agency in
order to obtain the initial ratings on the Certificates on the Closing Date. As
set forth on Exhibit L attached hereto is a list of all states where recordation
is required by either Rating Agency to obtain the initial ratings of the
Certificates. The Securities Administrator, the Trustee and the Custodian may
rely and shall be protected in relying upon the information contained in such
Exhibit L.

            In the case of Mortgage Loans that have been prepaid in full as of
the Closing Date, the Depositor, in lieu of delivering the above documents to
the Trustee, or the related Custodian on the Trustee's behalf, will cause the
applicable WF Servicer to remit to the WF Master Servicer for deposit in the WF
Master Servicer Custodial Account (with respect to each WF Master Serviced Loan)
or the WMMSC Master Servicer to deposit in the WMMSC Master Servicer Custodial
Account (with respect to each WMMSC Master Serviced Loan) the portion of such
payment that is required to be deposited in the such account pursuant to Section
3.09.

            Section 2.02 Acceptance by the Trustee or Custodian of the Mortgage
Loans. Subject to the provisions of the following paragraph, the Trustee
declares that it, or a Custodian as its agent, will hold the documents referred
to in Section 2.01 and the other documents delivered to it or the Custodian as
its agent, as the case may be, constituting the Mortgage Files, and that it will
hold such other assets as are included in the Trust Estate delivered to it, in
trust for the exclusive use and benefit of all present and future
Certificateholders. Upon execution and delivery of this document, the Trustee
shall deliver or cause the related Custodian to deliver to the Depositor and the
Master Servicers a certification in the form of Exhibit M hereto (the "Initial
Certification") to the effect that, except as may be specified in a list of
exceptions attached thereto, such Person has received the original Mortgage Note
relating to each of the Mortgage Loans for which such Person is acting as
Custodian listed on the Mortgage Loan Schedule.

            Within 90 days after the execution and delivery of this Agreement,
the Trustee shall review, or cause the related Custodian, on behalf of the
Trustee, to review, the Mortgage Files in such Person's possession, and shall
deliver, no later than 30 days after completion of such review, to the Depositor
and the Master Servicers a certification in the form of Exhibit N hereto (the
"Final Certification") to the effect that, as to each Mortgage Loan for which it
is acting as Custodian listed in the Mortgage Loan Schedule, except as may be
specified in a list of exceptions attached to such Final Certification, such
Mortgage File contains all of the items required to be delivered pursuant to
Section 2.01(b). In performing any such review, the Trustee and the Custodian
may conclusively rely on the purported genuineness of any such document and any
signature thereon.

            If, in the course of such review, the Trustee or a Custodian finds
any document constituting a part of a Mortgage File which does not meet the
requirements of Section 2.01 or is omitted from such Mortgage File, the Trustee
shall promptly notify or shall cause the Custodian promptly to notify, as the
case may be (and in no event more than 30 days after completion of the review),
the Master Servicer and the Depositor of such Mortgage Loan. The Depositor
hereby covenants and agrees that it will promptly correct or cure such defect
within 90 days from the date it was so notified of such defect and, if the
Depositor does not correct or cure such defect within such period, the Depositor
will either (a) substitute for the related Mortgage Loan a Substitute Mortgage
Loan, which substitution shall be accomplished in the manner and subject to the
conditions set forth below or (b) purchase such Mortgage Loan from the Trust at
the Purchase Price for such Mortgage Loan; provided, however, that in no event
shall such a substitution occur more than two years from the Closing Date;
provided, further, that such substitution or repurchase shall occur within 90
days of when such defect was discovered if such defect will cause the Mortgage
Loan not to be a "qualified mortgage" within the meaning of Section 860G(a)(3)
of the Code.

            If during the period of such review by the Trustee or the related
Custodian of any WF Master Serviced Loan, the Depositor, the WF Master Servicer,
the Securities Administrator, the Trustee or the related Custodian discovers a
breach by a WF Servicer or the Seller of any representation, warranty or
covenant under the Servicing Agreements or the Mortgage Loan Purchase Agreement
in respect of any WF Master Serviced Loan and such breach materially adversely
affects the interest of the Certificateholders in the related WF Master Serviced
Loan (provided that any such breach that causes the WF Master Serviced Loan not
to be a "qualified mortgage" within the meaning of Section 860G(a)(3) of the
Code shall be deemed to materially and adversely affect the interests of the
Certificateholders), then such party shall promptly so notify or cause the
related Custodian to promptly so notify the WF Master Servicer, the Seller, such
WF Servicer and the Depositor of such breach and request that the applicable WF
Servicer or the Seller, as applicable, cure such breach within 90 days of its
discovery or its receipt of notice of such breach. If the Seller or the
applicable WF Servicer, as the case may be, does not cure such breach in all
material respects during such period, the Trustee shall enforce the applicable
WF Servicer's or Seller's obligation, as the case may be, under the applicable
Servicing Agreement or the Mortgage Loan Purchase Agreement, as applicable, and
cause the applicable WF Servicer or Seller, as applicable, to either (a) solely
in the case of the Seller, substitute for the related WF Master Serviced Loan a
Substitute Mortgage Loan, which substitution shall be accomplished in the manner
and subject to the conditions set forth below or (b) purchase such WF Master
Serviced Loan from the Trust at the Purchase Price for such Mortgage Loan;
provided, however, that in no event shall such a substitution occur more than
two years from the Closing Date; provided, further, that such substitution or
repurchase must occur within 90 days of when such defect was discovered if such
defect will cause the Mortgage Loan not to be a "qualified mortgage" within the
meaning of Section 860G(a)(3) of the Code.

            It is understood that the scope of the Trustee and each Custodian's
review of the Mortgage Files is limited solely to confirming that the documents
listed in Section 2.01 have been received and further confirming that any and
all documents delivered pursuant to Section 2.01 appear on their face to have
been executed and relate to the applicable Mortgage Loans identified in the
related Mortgage Loan Schedule based solely upon the review of items (i) and
(xi) in the definition of Mortgage Loan Schedule. Neither the Trustee nor the
related Custodian shall have any responsibility for determining whether any
document is valid and binding, whether the text of any assignment or endorsement
is in proper or recordable form, whether any document has been recorded in
accordance with the requirements of any applicable jurisdiction, or whether a
blanket assignment is permitted in any applicable jurisdiction.

            In the event of a discovery of a breach of any representation or
warranty of a related WF Servicer or the Seller, the Trustee shall enforce the
rights of the Trust under the Servicing Agreements and the Mortgage Loan
Purchase Agreement for the benefit of the Certificateholders. In the event of a
breach of the representations or warranties with respect to the WF Master
Serviced Loans set forth in a Servicing Agreement, the Trustee shall enforce the
right of the Trust to be indemnified for such breach of representation or
warranty. In addition, if a breach of a representation with respect to a WF
Master Serviced Loan set forth in clauses (k) or (o) of paragraph 3 or clauses
(f) or (oo) of paragraph 4 of the Mortgage Loan Purchase Agreement occurs as a
result of a violation of an applicable predatory or abusive lending law, the
Trustee shall enforce the right of the Trust to reimbursement by the Seller for
all costs or damages incurred by the Trust as a result of the violation of such
law (such amount, the "WF Master Serviced Loan Reimbursement Amount"), but in
the case of a breach of a representation set forth in clauses (k) or (o) of
paragraph 3 of the Mortgage Loan Purchase Agreement, only to the extent the
applicable WF Servicer does not so reimburse the Trust. It is understood and
agreed that, except for any indemnification provided in the Servicing Agreements
and the payment of any WF Master Serviced Loan Reimbursement Amount, the
obligation of a WF Servicer or the Seller to cure or to repurchase (or in the
case of the Seller, to substitute for) any WF Master Serviced Loan as to which a
document is missing, a material defect in a constituent document exists or as to
which such a breach has occurred and is continuing shall constitute the sole
remedy against a WF Servicer or the Seller in respect of such omission, defect
or breach available to the Trustee on behalf of the Certificateholders.

            With respect to the representations and warranties relating to the
WF Master Serviced Loans set forth in the Mortgage Loan Purchase Agreement that
are made to the best of the Seller's knowledge or as to which the Seller had no
knowledge, if it is discovered by the Depositor, the WF Master Servicer or the
Trustee that the substance of such representation or warranty is inaccurate and
such inaccuracy materially and adversely affects the interest of the
Certificateholders in the related WF Master Serviced Loan then, notwithstanding
the Seller's lack of knowledge with respect to the substance of such
representation or warranty being inaccurate as the time the representation or
warranty was made, such inaccuracy shall be deemed a breach of the applicable
representation or warranty.

            It is understood and agreed that the representations and warranties
relating to the WF Master Serviced Loans set forth in the Mortgage Loan Purchase
Agreement shall survive delivery of the Mortgage Files to the Trustee or the
related Custodian and shall inure to the benefit of the Certificateholders
notwithstanding any restrictive or qualified endorsement or assignment. It is
understood and agreed that the obligations of the Seller set forth in this
Section 2.02 to cure, substitute for or repurchase a WF Master Serviced Loan
pursuant to the Mortgage Loan Purchase Agreement constitute the sole remedies
available to the Certificateholders and to the Trustee on their behalf
respecting a breach of the representations and warranties contained in the
Mortgage Loan Purchase Agreement.

            The representations and warranties of each WF Servicer with respect
to the applicable WF Master Serviced Loans in the related Servicing Agreement,
which have been assigned to the Trustee hereunder, were made as of the date
specified in such Servicing Agreement. To the extent that any fact, condition or
event with respect to a WF Master Serviced Loan constitutes a breach of both (i)
a representation or warranty of a WF Servicer under the related Servicing
Agreement and (ii) a representation or warranty of the Seller under the Mortgage
Loan Purchase Agreement, the only right or remedy of the Trustee or of any
Certificateholder shall be the Trustee's right to enforce the obligations of the
applicable WF Servicer under any applicable representation or warranty made by
it. The Trustee acknowledges that the Seller shall have no obligation or
liability with respect to any breach of a representation or warranty made by it
with respect to the Mortgage Loans if the fact, condition or event constituting
such breach also constitutes a breach of a representation or warranty made by
the applicable WF Servicer in the applicable Servicing Agreement, without regard
to whether such WF Servicer fulfills its contractual obligations in respect of
such representation or warranty. The Trustee further acknowledges that the
Depositor shall have no obligation or liability with respect to any breach of
any representation or warranty with respect to the WF Master Serviced Loans
(except as set forth in Section 2.04(b)) under any circumstances.

            With respect to each Substitute Mortgage Loan the Seller shall
deliver to the Trustee (or a Custodian on behalf of the Trustee), for the
benefit of the Certificateholders, the Mortgage Note, the Mortgage, the related
Assignment of Mortgage (except for any Mortgage which has been recorded in the
name of MERS or its designee), and such other documents and agreements as are
otherwise required by Section 2.01, with the Mortgage Note endorsed and the
Mortgage assigned as required by Section 2.01. No substitution is permitted to
be made in any calendar month after the Determination Date for such month.
Monthly Payments due with respect to any such Substitute Mortgage Loan in the
month of substitution shall not be part of the Trust Estate and will be retained
by the Depositor. For the month of substitution, distributions to
Certificateholders will include the Monthly Payment due for such month on any
Defective Mortgage Loan for which the Depositor has substituted a Substitute
Mortgage Loan.

            The related Master Servicer shall amend the Mortgage Loan Schedule
for the benefit of the Certificateholders to reflect the removal of each
Mortgage Loan that has become a Defective Mortgage Loan and the substitution of
the Substitute Mortgage Loan or Loans and the related Master Servicer shall
deliver the amended Mortgage Loan Schedule to the Securities Administrator, the
Trustee and the related Custodian. Upon such substitution of a WF Master
Serviced Loan by the Seller, each Substitute Mortgage Loan shall be subject to
the terms of this Agreement in all respects, and the Seller shall be deemed to
have made to the Trustee with respect to such Substitute Mortgage Loan, as of
the date of substitution, the representations and warranties made pursuant to
paragraph 4 of the Mortgage Loan Purchase Agreement. Upon such substitution of a
WMMSC Master Serviced Loan by the Representing Party, each Substitute Mortgage
Loan shall be subject to the terms of this Agreement in all respects, and the
Representing Party shall be deemed to have made to the Trustee with respect to
such Substitute Mortgage Loan, as of the date of substitution, the
representations and warranties made pursuant to Section 2.04(a) and (b) hereof.
Upon any such substitution and the deposit to the applicable Master Servicer
Custodial Account of any required Substitution Adjustment Amount (as described
in the next paragraph) and receipt by the Trustee of a Request for Release, the
Trustee shall release, or shall direct the related Custodian to release, the
Mortgage File relating to such Defective Mortgage Loan to the Seller or the
Representing Party, as applicable, and shall execute and deliver at the Seller's
or the Representing Party's direction such instruments of transfer or assignment
prepared by the Seller or the Representing Party, as applicable, in each case
without recourse, as shall be necessary to vest title in the Seller or
Representing Party, or its designee, to the Trustee's interest in any Defective
Mortgage Loan substituted for pursuant to this Section 2.02.

            For any month in which the Seller or Representing Party substitutes
one or more Substitute Mortgage Loans for one or more Defective Mortgage Loans,
the amount (if any) by which the aggregate principal balance of all such
Substitute Mortgage Loans substituted by the Seller or Representing Party, as
the case may be, in a Loan Group as of the date of substitution is less than the
aggregate Stated Principal Balance of all such Defective Mortgage Loans in a
Loan Group substituted by the Seller or Representing Party (after application of
the principal portion of the Monthly Payments due in the month of substitution)
(the "Substitution Adjustment Amount" for such Loan Group) plus an amount equal
to the aggregate of any unreimbursed Advances with respect to such Defective
Mortgage Loans shall be remitted by the Seller or the Representing Party to the
applicable Master Servicer for deposit to the related Master Servicer Custodial
Account on or before the 18th of the month succeeding the calendar month during
which the related Mortgage Loan is required to be purchased or replaced
hereunder.

            The Trustee shall retain or shall cause the related Custodian to
retain, as applicable, possession and custody of each Mortgage File in
accordance with and subject to the terms and conditions set forth herein. The
related Master Servicer shall cause to be promptly delivered to the Trustee or
the Custodian on behalf of the Trustee, as the case may be, upon the execution
or, in the case of documents requiring recording, receipt thereof, the originals
of such other documents or instruments constituting the Mortgage File as come
into the related Master Servicer's possession from time to time.

            The Trustee or the related Custodian, on behalf of the Trustee,
shall be under no duty or obligation (i) to inspect, review or examine any such
documents, instruments, certificates or other papers to determine that they are
genuine, enforceable, or appropriate for the represented purpose or that they
are other than what they purport to be on their face or (ii) to determine
whether any Mortgage File should include any of the documents specified in
Section 2.01(b)(iv), (vi), (vii), (viii) and (ix). In connection with making the
certifications required hereunder, to the extent a title search or opinion of
counsel had been provided in lieu of a title policy for any Mortgage Loan, the
Trustee or the applicable Custodian on its behalf, as applicable, shall only be
responsible for confirming that a title search or opinion of counsel has been
provided for such Mortgage Loan.

      Servicer or its property is subject, or result in the violation of any
      law, rule, regulation, order, judgment or decree to which the WF Master

      financial condition, properties or assets of the WF Master Servicer, or in
      any material impairment of the right or ability of the WF Master Servicer
      to carry on its business substantially as now conducted or which would
      draw into question the validity of this Agreement or the WF Master
      Serviced Loans or of any action taken or to be taken in connection with
      the obligations of the WF Master Servicer contemplated herein, or which
      would materially impair the ability of the WF Master Servicer to perform

representations and warranties to the Depositor, the WF Master Servicer, the
Securities Administrator and the Trustee, as of the Closing Date:

      the states where a Mortgaged Property securing a WMMSC Master Serviced

      herewith; the execution, delivery and performance of this Agreement
      (including all instruments of transfer to be delivered pursuant to this
      Agreement) by the WMMSC Master Servicer and the consummation of the

      constitute a default under or result in the acceleration of any obligation
      under, any agreement, indenture or loan or credit agreement or other
      instrument to which the WMMSC Master Servicer or its property is subject,

      the WMMSC Master Servicer which, either individually or in the aggregate,
      would result in any material adverse change in the business, operations,
      financial condition, properties or assets of the WMMSC Master Servicer, or
      in any material impairment of the right or ability of the WMMSC Master
      Servicer to carry on its business substantially as now conducted or which
      would draw into question the validity of this Agreement or the WMMSC
      Master Serviced Loans or of any action taken or to be taken in connection

            The representations and warranties made pursuant to this Section
2.03 shall survive delivery of the respective Mortgage Files to the Trustee for
the benefit of the Certificateholders.

      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 the rent
      other than pre-established increases set forth in the lease; (4) the
      original term of such lease in 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;

            (xxiii) All of the WMMSC Master Serviced Loans have due-on-sale
      clauses; however, the due on sale provisions may not be exercised at the
      time of a transfer if prohibited by law;

            (xxiv) With respect to each WMMSC Master Serviced Loan that is a
      Cooperative Loan, the Cooperative Stock that is pledged as security for
      the Cooperative Loan is held by a person as a tenant-stockholder (as
      defined in Section 216 of the Code) in a cooperative housing corporation
      (as defined in Section 216 of the Code);

            (xxv) Each WMMSC Master Serviced Loan that is a Cooperative Loan is
      secured by a valid, subsisting and enforceable (except as such enforcement
      may be limited by laws affecting the enforcement of creditors' rights
      generally and principles of equity) perfected first lien and security
      interest in the related Cooperative Stock securing the related Mortgage
      Note, subject only to (a) liens of the Cooperative for unpaid assessments

      Agreement;

            (xxvi) With respect to any WMMSC Master Serviced Loan as to which an
      affidavit has been delivered to the Trustee or related Custodian
      certifying that the original Mortgage Note is lost or destroyed, if such
      WMMSC Master Serviced Loan is subsequently in default, the enforcement of
      such WMMSC Master Serviced Loan or of the related Mortgage by or on behalf
      of the Trust will not be materially adversely affected by the absence of
      the original Mortgage Note (or portion thereof, as applicable);

            (xxvii) Based upon an appraisal of the Mortgaged Property securing
      each WMMSC Master Serviced Loan, as of the Cut-Off Date 100% (by aggregate
      Stated Principal Balance as of the Cut-Off Date) of the WMMSC Master
      Serviced Loans in Loan Group 1 had a current Loan-to-Value Ratio less than

      Loans in Loan Group 3, respectively, were originated under full
      documentation programs;

            (xxx) No WMMSC Master Serviced Loan is a "high cost" loan as defined
      under any federal, state or local law applicable to such Mortgage at the
      time of its origination;

            (xxxi) Each WMMSC Master Serviced Loan constitutes a "qualified
      mortgage" under Section 860G(a)(3)(A) of the Code and Treasury Regulations

            (xxxii) The Mortgage Note and the Mortgage relating to each WMMSC
      Master Serviced Loan are genuine, and each is the legal, valid and binding
      obligation of the maker thereof and each party assuming liability

      rights generally and except that the equitable remedy of specific
      performance and other equitable remedies are subject to the discretion of
      the courts;

            (xxxiii) With respect to each WMMSC Master Serviced Loan, there are

      lien of the related Mortgage, which are not insured against by the related
      mortgagee's policy of title insurance; and

            (xxxiv) No WMMSC Master Serviced Loan is a High Cost Loan or Covered
      Loan (as such terms are defined in the Standard & Poor's LEVELS(R)
      Glossary in effect on the Closing Date, which is now Version 5.6 Revised,

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

            (b) The Depositor hereby represents and warrants to the Trustee with
respect to the Mortgage Loans or each Mortgage Loan, as the case may be, as of
the date hereof or such other date set forth herein that as of the Closing Date:

            (i) Immediately prior to the transfer and assignment contemplated
       herein, the Depositor was the sole owner and holder of the Mortgage Loans.
      The Mortgage Loans were not assigned or pledged by the Depositor and the
      Depositor had good and marketable title thereto, and the Depositor had
      full right to transfer and sell the Mortgage Loans to the Trustee free and
      clear of any encumbrance, participation interest, lien, equity, pledge,
      claim or security interest and had full right and authority subject to no
      interest or participation in, or agreement with any other party to sell or
      otherwise transfer the Mortgage Loans.

            (ii) As of the Closing Date, the Depositor has transferred all
      right, title and interest in the Mortgage Loans to the Trustee on behalf
      of the Trust.

            (iii) As of the Closing Date, the Depositor has not transferred the
      Mortgage Loans to the Trustee on behalf of the Trust with any intent to
      hinder, delay or defraud an of its creditors.

            It is understood and agreed that the representations and warranties
set forth in this Section 2.04 shall survive delivery of the respective Mortgage
Files to the Trustee or the related Custodian and shall inure to the benefit of
the Trustee, notwithstanding any restrictive or qualified endorsement or
assignment.

            Upon discovery by any of the Depositor, the Representing Party,
either Master Servicer, the Trustee or the related Custodian that any of the
representations and warranties set forth in this Section 2.04 is not accurate
(referred to herein as a "breach") and 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 (such Custodian being so obligated under the applicable Custodial
Agreement); provided that any such breach that causes the Mortgage Loan not to
be a "qualified mortgage" within the meaning of Section 860G(a)(3) of the Code
shall be deemed to materially and adversely affect the interests of the
Certificateholders. Within 90 days of its discovery or its receipt of notice of
any such breach, the Representing Party, if such breach relates to a
representation and warranty set forth in Section 2.04(a), or the Depositor, if
such breach relates to a representation and warranty set forth in Section
2.04(b), 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 Trustee at a price equal to the Purchase Price or (ii) if within two years
of the Closing Date, substitute for such Mortgage Loan in the manner described
in Section 2.02; provided that if the breach would cause the Mortgage Loan to be
other than a "qualified mortgage" as defined in Section 860G(a)(3) of the Code,
any such repurchase or substitution must occur within 90 days from the date the
breach was discovered. In addition to the foregoing, if a breach of the
representation set forth in clause (vii) or clause (xxxiv) of Section 2.04(a)
occurs as a result of a violation of an applicable predatory or abusive lending
law, the Representing Party shall reimburse the Trust for all costs or damages
incurred by the Trust as a result of the violation of such law (such amount, the
"WMMSC Master Serviced Loan Reimbursement Amount"). The Purchase Price of any
repurchase described in this paragraph, the Substitution Adjustment Amount, if
any, and any WMMSC Master Serviced Loan Reimbursement Amount shall be remitted
to the applicable Master Servicer for deposit to the related Master Servicer
Custodial Account. It is understood and agreed that, except with respect to the
second preceding sentence, the obligation of the Representing Party or the
Depositor, as applicable, to repurchase or substitute for any Mortgage Loan or
Mortgaged Property as to which such a breach has occurred and is continuing
shall constitute the sole remedy respecting such breach available to
Certificateholders, or to the Trustee on behalf of Certificateholders, and such
obligation shall survive until termination of the Trust hereunder.

                                   ARTICLE III

                       ADMINISTRATION AND MASTER SERVICING
                                OF MORTGAGE LOANS

            Section 3.01 Master Servicing of the Mortgage Loans.

            (a) For and on behalf of the Certificateholders, the WF Master
Servicer shall supervise, monitor and oversee the obligations of the WF
Servicers to service and administer their respective WF Master Serviced Loans in
accordance with the terms of the applicable Servicing Agreement and shall have
full power and authority to do any and all things which it may deem necessary or
desirable in connection with such master servicing and administration. In
performing its obligations hereunder, the WF Master Servicer shall act in a
manner consistent with this Agreement, subject to the prior sentence, and with
Customary Servicing Procedures. Furthermore, the WF Master Servicer shall
oversee and consult with each WF Servicer as necessary from time-to-time to
carry out the WF Master Servicer's obligations hereunder, shall receive, review
and evaluate all reports, information and other data provided to the WF Master
Servicer by each WF Servicer and shall cause each WF Servicer to perform and
observe the covenants, obligations and conditions to be performed or observed by
such WF Servicer under the applicable Servicing Agreement. The WF Master
Servicer shall independently and separately monitor each WF Servicer's servicing
activities with respect to each related WF Master Serviced Loan, reconcile the
results of such monitoring with such information provided in the previous
sentence on a monthly basis and coordinate corrective adjustments to the WF
Servicers' and the WF Master Servicer's records, and based on such reconciled
and corrected information, prepare the WF Master Servicer's Certificate and any
other information and statements required hereunder. The WF Master Servicer
shall reconcile the results of its Mortgage Loan monitoring with the actual
remittances of the WF Servicers to the WF Master Servicer Custodial Account
pursuant to the applicable Servicing Agreements.

            Continuously from the date hereof until the principal and interest
on all WF Master Serviced Loans are paid in full, the WF Master Servicer shall
enforce the obligations of the WF Servicers to collect all payments due under
the terms and provisions of the WF Master Serviced Loans when the same shall
become due and payable to the extent such procedures shall be consistent with
the applicable Servicing Agreement.

            The relationship of the WF Master Servicer (and of any successor to
the WF Master Servicer as master servicer under this Agreement) to the Trustee
and the Securities Administrator under this Agreement is intended by the parties
to be that of an independent contractor and not that of a joint venturer,
partner or agent.

            (b) The WMMSC Master Servicer shall act as master servicer to
service and administer the WMMSC Master Serviced Loans on behalf of the Trust in
accordance with the terms hereof, consistent with prudent mortgage loan
servicing practices and (unless inconsistent with prudent mortgage loan
servicing practices) in the same manner in which, and with the same care, skill,
prudence and diligence with which, it services and administers similar mortgage
loans for other portfolios, and shall have full power and authority to do or
cause to be done any and all things in connection with such servicing and
administration which a prudent servicer of mortgage loans would do under similar
circumstances, including, without limitation, the power and authority to bring
actions and defend the Trust Estate on behalf of the Trust in order to enforce
the terms of the related Mortgage Notes. The WMMSC Master Servicer may perform
its master servicing responsibilities through agents or independent contractors,
including the WMMSC Servicers, but shall not thereby be released from any of its
master servicing or servicing responsibilities hereunder and the WMMSC Master
Servicer shall diligently pursue all of its rights against such agents or
independent contractors.

            The WMMSC Master Servicer shall make reasonable efforts to collect
or cause to be collected all payments called for under the terms and provisions
of the WMMSC Master Serviced Loans and shall, to the extent such procedures
shall be consistent with this Agreement and the terms and provisions of any
Primary Mortgage Insurance Policy, any FHA insurance policy or VA guaranty, any
hazard insurance policy, and federal flood insurance, cause to be followed such
collection procedures as are followed with respect to mortgage loans comparable
to the WMMSC Master Serviced Loans and held in portfolios of responsible
mortgage lenders in the local areas where each Mortgaged Property is located.
The WMMSC Master Servicer shall enforce "due-on-sale" clauses with respect to
the related Mortgage Loans, to the extent permitted by law, subject to the
provisions set forth in Section 3.14.

      Consistent with the foregoing, the WMMSC Master Servicer may, in
accordance with prudent mortgage loan servicing practices, (i) waive or cause to
be waived any assumption fee or late payment charge in connection with the
prepayment of any WMMSC Master Serviced Loan and (ii) only upon determining that
the coverage of any applicable insurance policy or guaranty related to a WMMSC
Master Serviced Loan will not be materially adversely affected, arrange a
schedule, running for no more than 180 days after the first delinquent Due Date,
for payment of any delinquent installment on any Mortgage Note or for the
liquidation of delinquent items. The WMMSC Master Servicer shall have the right,
but not the obligation, to purchase any WMMSC Master Serviced Loan delinquent 90
consecutive days or more for an amount equal to its Purchase Price; provided,
however, that the aggregate Purchase Price of WMMSC Master Serviced Loans so
purchased pursuant to this sentence shall not exceed one-half of one percent
(0.50%) of the aggregate Stated Principal Balance, as of the Cut-Off Date, of
all WMMSC Master Serviced Loans. For purposes of this paragraph, a WMMSC Master
Serviced Loan is considered delinquent for 90 consecutive days if a Monthly
Payment is not received by the first day of the third month following the month
during which such payment was due.

      Consistent with the terms of this Section 3.01, the WMMSC Master Servicer
may waive, modify or vary any term of any WMMSC Master Serviced Loan or consent
to the postponement of strict compliance with any such term or in any manner
grant indulgence to any Mortgagor if it has determined, exercising its good
faith business judgment in the same manner as it would if it were the owner of
the related WMMSC Master Serviced Loan, that the security for, and the timely
and full collectability of, such Mortgage Loan would not be adversely affected
by such waiver, modification, postponement or indulgence; provided, however,
that the WMMSC Master Servicer shall not permit any modification with respect to
any WMMSC Master Serviced Loan that would (i) change the applicable Mortgage
Interest Rate, defer (except as permitted in the preceding paragraph) or forgive
the payment of any principal or interest, reduce the outstanding principal
balance (except for actual payments of principal) or extend the final maturity
date with respect to such Mortgage Loan, or (ii) be inconsistent with the terms
of any applicable Primary Mortgage Insurance Policy, FHA insurance policy, VA
guaranty, hazard insurance policy or federal flood insurance policy.
Notwithstanding the foregoing, the WMMSC Master Servicer shall not permit any
modification with respect to any WMMSC Master Serviced Loan that would both
constitute a sale or exchange of such Mortgage Loan within the meaning of
Section 1001 of the Code (including any proposed, temporary or final regulations
promulgated thereunder) (other than in connection with a proposed conveyance or
assumption of such Mortgage Loan that is treated as a Principal Prepayment or in
a default situation) and cause any REMIC to fail to qualify as such under the
Code. The WMMSC Master Servicer shall be entitled to approve a request from a
Mortgagor for a partial release of the related Mortgaged Property, the granting
of an easement thereon in favor of another Person, any alteration or demolition
of the related Mortgaged Property or other similar matters if it has determined,
exercising its good faith business judgment in the same manner as it would if it
were the owner of the related WMMSC Master Serviced Loan, that the security for,
and the timely and full collectability of, such WMMSC Master Serviced Loan would
not be adversely affected thereby and that no REMIC created hereunder would fail
to continue to qualify as a REMIC under the Code as a result thereof and that no
tax on "prohibited transactions" or "contributions" after the startup day would
be imposed on any REMIC as a result thereof.

      The WMMSC Master Servicer is hereby authorized and empowered by the Trust
to execute and deliver or cause to be executed and delivered on behalf of the
Holders of the Regular Certificates and the Class 1-A-LR Certificate, and the
Trust or any of them, any and all instruments of satisfaction or cancellation,
or of partial or full release, discharge or modification, assignments of
Mortgages and endorsements of Mortgage Notes in connection with refinancings (in
jurisdictions where such assignments are the customary and usual standard of
practice of mortgage lenders) and all other comparable instruments, with respect
to the WMMSC Master Serviced Loans and with respect to the Mortgaged Properties.
The WMMSC Master Servicer is hereby further authorized and empowered by the
Trust to execute and deliver or cause to be executed and delivered on behalf of
the Holders of the Regular Certificates and the Residual Certificates and the
Trust, or any of them, such instruments of assignment or other comparable
instruments as the WMMSC Master Servicer shall, in its sole judgment, deem
appropriate in order to register any WMMSC Master Serviced Loan on the MERS
system or to cause the removal of any WMMSC Master Serviced Loan from
registration thereon. Any expenses incurred in connection with the actions
described in the preceding sentence shall be borne by the WMMSC Master Servicer
with no right of reimbursement; provided, however, that any such expenses
incurred as a result of any termination by MERS of the MERS system shall be
reimbursable to the WMMSC Master Servicer. The Trustee on behalf of the Trust
shall execute and furnish to the WMMSC Master Servicer, at the WMMSC Master
Servicer's direction, any powers of attorney and other documents prepared by the
WMMSC Master Servicer and determined by the WMMSC Master Servicer to be
necessary or appropriate to enable the WMMSC Master Servicer to carry out its
supervisory, servicing and administrative duties under this Agreement.

            In connection with the servicing and administering of each WMMSC
Master Serviced Loan, the WMMSC Master Servicer and any affiliate of the WMMSC
Master Servicer (i) may perform services such as appraisals, default management
and (in the case of affiliates only) brokerage services that are not customarily
provided by servicers of mortgage loans, and shall be entitled to reasonable
compensation therefor and (ii) may, at its own discretion and on behalf of the
Trust, obtain credit information in the form of a "credit score" from a credit
repository.

            Section 3.02 Monitoring of WF Servicers.

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

            (b) The WF Master Servicer, for the benefit of the Trustee and the
Certificateholders, shall enforce the obligations of each WF Servicer under the
related Servicing Agreement, and shall, in the event that a WF Servicer fails to
perform its obligations in accordance with the related Servicing Agreement,
subject to the preceding paragraph, terminate the rights and obligations of such
WF Servicer thereunder and act as successor WF Servicer of the related WF Master
Serviced Loans under the applicable Servicing Agreement (except, in the case of
the termination of Wells Fargo Bank as a Servicer under the Wells Fargo
Servicing Agreement, the Trustee shall either act as successor Servicer or shall
appoint a successor Servicer of the related WF Master Serviced Loans under the
Wells Fargo Servicing Agreement) or cause the Trustee to enter in to a new
Servicing Agreement with a successor Servicer selected by the WF Master Servicer
(except, in the case of the Wells Fargo Servicing Agreement, the Trustee shall
select the successor Servicer); provided, however, it is understood and
acknowledged by the parties hereto that there will be a period of transition
(not to exceed 90 days) before the actual servicing functions can be fully
transferred to such successor WF Servicer. Such enforcement, including, without
limitation, the legal prosecution of claims, termination of Servicing Agreements
and the pursuit of other appropriate remedies, shall be in such form and carried
out to such an extent and at such time as the WF Master Servicer, in its good
faith business judgment, would require were it the owner of the related WF
Master Serviced Loans. The WF Master Servicer and Trustee, as applicable, shall
pay the costs of such enforcement at its own expense, and shall be reimbursed
therefor only (i) from a general recovery resulting from such enforcement to the
extent, if any, that such recovery exceeds all amounts due in respect of the
related WF Master Serviced Loan or (ii) from a specific recovery of costs,
expenses or attorneys fees against the party whom such enforcement is directed,
provided that the WF Master Servicer and the Trustee, as applicable, shall not
be required to prosecute or defend any legal action except to the extent that
the WF Master Servicer or the Trustee, as applicable, shall have received
reasonable indemnity for its costs and expenses in pursuing such action.

            (c) To the extent that the costs and expenses of the WF Master
Servicer or the Trustee, as applicable, related to any termination of a WF
Servicer, appointment of a successor WF Servicer or the transfer and assumption
of servicing by the WF Master Servicer or the Trustee, as applicable, with
respect to any Servicing Agreement (including, without limitation, (i) all legal
costs and expenses and all due diligence costs and expenses associated with an
evaluation of the potential termination of the WF Servicer as a result of an
Event of Default by such WF Servicer and (ii) all costs and expenses associated
with the complete transfer of servicing, including all servicing files and all
servicing data and the completion, correction or manipulation of such servicing
data as may be required by the successor WF Servicer to correct any errors or
insufficiencies in the servicing data or otherwise to enable the successor
Servicer to service the WF Master Serviced Loans in accordance with the related
Servicing Agreement) are not fully and timely reimbursed by the terminated WF
Servicer, the WF Master Servicer or the Trustee, as applicable, shall be
entitled to reimbursement of such costs and expenses from the WF Master Servicer
Custodial Account.

            (d) To the extent that any Servicing Transfer Costs are not fully
and timely reimbursed by the terminated Servicer, the applicable Master Servicer
or the Trustee, as applicable, shall be entitled to reimbursement of such costs
and expenses from the Master Servicer Custodial Account; provided that if such
Servicing Transfer Costs are ultimately reimbursed by the terminated Servicer,
then the applicable Master Servicer or the Trustee, as applicable, shall remit
such amounts that are reimbursed by the terminated Servicer to the Master
Servicer Custodial Account.

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

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

            Section 3.03 Fidelity Bond; Errors and Omissions Insurance. Each
Master Servicer and WMMSC Servicer shall maintain, at its own expense, a blanket
fidelity bond and an errors and omissions insurance policy, with broad coverage
on all officers, employees or other persons involved in the performance of its
obligations as Master Servicer hereunder or with respect to a WMMSC Servicer,
their obligations under the applicable Servicing Contract. These policies must
insure the Master Servicers and WMMSC Servicers against losses resulting from
dishonest or fraudulent acts committed by the related Master Servicer's or WMMSC
Servicer's personnel, any employees of outside firms that provide data
processing services for the related Master Servicer or WMMSC Servicer, and
temporary contract employees or student interns. No provision of this Section
3.03 requiring such fidelity bond and errors and omissions insurance shall
diminish or relieve the Master Servicers or WMMSC Servicer from its duties and
obligations as set forth in this Agreement or in a Servicing Contract, as
applicable. The minimum coverage under any such bond and insurance policy shall
be at least equal to the corresponding amounts required by FNMA in the FNMA
Servicing Guide or by FHLMC in the FHLMC Sellers' & Servicers' Guide, as amended
or restated from time to time, or in an amount as may be permitted to the Master
Servicers or WMMSC Servicer by express waiver of FNMA or FHLMC. In the event
that any such policy or bond ceases to be in effect, the Master Servicers and
WMMSC Servicers shall obtain a comparable replacement policy or bond from an
insurer or issuer, meeting the requirements set forth above as of the date of
such replacement.

            Section 3.04 Access to Certain Documentation.

            The WMMSC Master Servicer and the WF Master Servicer shall provide,
and the WF Master Servicer shall cause each WF Servicer to provide in accordance
with the related Servicing Agreement, to the OCC, the OTS, the FDIC and to
comparable regulatory authorities supervising Holders of Certificates and the
examiners and supervisory agents of the OCC, the OTS, the FDIC and such other
authorities, access to the documentation required by applicable regulations of
the OCC, the OTS, the FDIC and such other authorities with respect to the
Mortgage Loans. Such access shall be afforded without charge, but only upon
reasonable and prior written request and during normal business hours at the
offices designated by the related Master Servicer and the related Servicer. In
fulfilling such request for access, the WF Master Servicer shall not be
responsible to determine the sufficiency of any information provided by such WF
Servicer. Nothing in this Section 3.04 shall limit the obligation of the related
Master Servicer and the related Servicer to observe any applicable law and the
failure of the related Master Servicer or the related Servicer to provide access
as provided in this Section 3.04 as a result of such obligation shall not
constitute a breach of this Section 3.04.

            Section 3.05 Maintenance of Primary Mortgage Insurance Policy;
Claims.

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

            (b) The WF Master Servicer agrees to present, or to cause each WF
Servicer (to the extent required under the related Servicing Agreement) to
present, on behalf of the Trustee and the Certificateholders, claims to the
insurer under any Primary Mortgage Insurance Policies and, in this regard, to
take such reasonable action as shall be necessary to permit recovery under any
Primary Mortgage Insurance Policies respecting defaulted WF Master Serviced
Loans. Pursuant to Sections 3.08 and 3.09, any amounts collected by the WF
Master Servicer or any WF Servicer under any Primary Mortgage Insurance Policies
shall be deposited in the WF Master Servicer Custodial Account, subject to
withdrawal pursuant to Section 3.11.

            (c) The WMMSC Master Servicer shall use commercially reasonable
efforts to keep, and to cause the WMMSC Servicers to keep, in full force and
effect each Primary Mortgage Insurance Policy with respect to a WMMSC Master
Serviced Loan with a Loan-to-Value Ratio in excess of 80%, until no longer
required or until no longer permitted under applicable law, and WMMSC Master
Servicer shall use commercially reasonable efforts to keep in full force and
effect each Special Primary Mortgage Insurance Policy, if any. Notwithstanding
the foregoing, the WMMSC Master Servicer shall have no obligation to maintain
any Primary Mortgage Insurance Policy for a WMMSC Master Serviced Loan for which
the outstanding Principal Balance thereof at any time subsequent to origination
was 80% or less of the Appraised Value of the related Mortgaged Property, unless
required by applicable law.

            Unless required by applicable law, the WMMSC Master Servicer shall
not cancel or refuse to renew, or allow any WMMSC Servicer under its supervision
to cancel or refuse to renew, any Primary Mortgage Insurance Policy in effect at
the date of the initial issuance of the Certificates that is required to be kept
in force hereunder; provided, however, that neither the WMMSC Master Servicer
nor any WMMSC Servicer shall advance funds for the payment of any premium due
under any Primary Mortgage Insurance Policy if it shall determine that such an
advance would be a Nonrecoverable Advance.

            The WMMSC Master Servicer agrees to present, or cause to be
presented, on behalf of and for the benefit of the Trust, claims under the
Primary Mortgage Insurance Policy respecting any WMMSC Master Serviced Loan, and
in this regard to take such reasonable actions as shall be necessary to permit
recovery under such Primary Mortgage Insurance Policy.

            Section 3.06 Rights of the Depositor, the Securities Administrator
and the Trustee in Respect of the Master Servicers.

            The Depositor may, but is not obligated to, enforce the obligations
of the Master Servicers hereunder and may, but is not obligated to, perform, or
cause a designee to perform, any defaulted obligation of either Master Servicer
hereunder and in connection with any such defaulted obligation to exercise the
related rights of a Master Servicer hereunder; provided that a Master Servicer
shall not be relieved of any of its obligations hereunder by virtue of such
performance by the Depositor or its designee. None of the Securities
Administrator, the Trustee or the Depositor shall have any responsibility or
liability for any action or failure to act by either Master Servicer and the
Securities Administrator, the Trustee or the Depositor shall not be obligated to
supervise the performance of a Master Servicer hereunder or otherwise.

            Section 3.07 Trustee to Act as Master Servicer.

            In the event a Master Servicer or any successor master servicer
shall for any reason no longer be a Master Servicer hereunder (including by
reason of an Event of Default), the Trustee as trustee hereunder shall within 90
days of such time, assume, if it so elects, or shall appoint a successor Master
Servicer to assume, all of the rights and obligations of such Master Servicer
hereunder and all of the rights and obligations of such Master Servicer under
the Servicing Contracts or Servicing Agreements, as applicable, with respect to
the related Mortgage Loans, unless the Trustee elects to terminate the Servicing
Contracts or Servicing Agreements, as applicable, with respect to such Mortgage
Loans in accordance with the terms thereof. Unless the Trustee so elects to
terminate the Servicing Contracts or Servicing Agreements, as applicable, the
Trustee, its designee or the successor master servicer for the Trustee shall be
deemed to have assumed all of the applicable Master Servicer's interest therein
with respect to the related Mortgage Loans and to have replaced the applicable
Master Servicer as a party to the Servicing Contracts or Servicing Agreements,
as applicable, to the same extent as if the rights and duties under the
Servicing Contracts or Servicing Agreements relating to such Mortgage Loans had
been assigned to the assuming party, except that the related Master Servicer
shall not thereby be relieved of any liability or obligations under the
Servicing Contracts or Servicing Agreements, as applicable, with respect to the
related Master Servicer's duties to be performed prior to its termination
hereunder. Any such assumption shall be subject to Sections 7.02 and 8.05.

            In addition, with respect to the WMMSC Master Serviced Loans for
which the WMMSC Master Servicer has not entered into a Servicing Contract, if
the WMMSC Master Servicer shall for any reason no longer be the WMMSC Master
Servicer, the Trustee as trustee hereunder shall assume, within 90 days of such
time, or shall appoint a successor Servicer to assume, all of the rights and
obligations of the WMMSC Master Servicer as WMMSC Servicer with respect to such
WMMSC Mortgage Loans.

            A Master Servicer at its expense shall, upon request of the Trustee,
deliver to the assuming party all documents and records relating to the
Servicing Contracts and the Mortgage Loans then being master serviced and
serviced by such Master Servicer and an accounting of amounts collected and held
by such Master Servicer, and shall transfer control of the related Master
Servicer Custodial Account, Escrow Accounts and any investment accounts to the
successor Master Servicer, and otherwise use its best efforts to effect the
orderly and efficient transfer of the rights and duties under the related
Servicing Contracts relating to such Mortgage Loans to the assuming party. The
Trustee shall be entitled to be reimbursed from the predecessor Master Servicer
(or the Trust if the predecessor Master Servicer is unable to fulfill such
obligations) for all Master Servicing Transfer Costs.

            Section 3.08 Servicer Custodial Accounts and Escrow Accounts.

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

            The WF Master Servicer shall also enforce the obligation of each WF
Servicer to establish and maintain a Buy-Down Account in accordance with the
applicable Servicing Agreement, with records to be kept with respect thereto on
a Mortgage Loan by Mortgage Loan basis, into which accounts any Buy-Down Funds
shall be deposited within 48 hours (or as of such other time specified in the
related Servicing Agreement) of receipt thereof. The WF Master Servicer is
hereby authorized to make withdrawals from and deposits to the related Buy-Down
Account for purposes required or permitted by this Agreement. In addition, the
WF Master Servicer shall enforce the obligation of each WF Servicer to withdraw
from the Buy-Down Account and deposit in immediately available funds in the
Servicer Custodial Account an amount which, when added to such Mortgagor's
payment, will equal the full monthly payment due under the related Mortgage
Note.

            To the extent required by the related Servicing Agreement and by the
related Mortgage Note and not violative of current law, the WF Master Servicer
shall require each WF Servicer to establish and maintain one or more escrow
accounts (for each WF Servicer, collectively, the "WF Escrow Account") and
deposit and retain therein all collections from the Mortgagors (or Advances by
such WF Servicer) for the payment of taxes, assessments, hazard insurance
premiums or comparable items for the account of the Mortgagors. Nothing herein
shall require the WF Master Servicer to compel a WF Servicer to establish a WF
Escrow Account in violation of applicable law.

            (b) The WMMSC Master Servicer shall cause to be established and
maintained by each WMMSC Servicer under the WMMSC Master Servicer's supervision
a Servicer Custodial Account and one or more escrow accounts (the "WMMSC Escrow
Accounts") and shall deposit or cause to be deposited therein daily the amounts
related to the WMMSC Master Serviced Loans required by the Servicing Contracts
to be so deposited. The WMMSC Master Servicer or the WMMSC Servicer shall
deposit in the applicable WMMSC Escrow Account on a daily basis all Escrow
Payments received by it. Proceeds received with respect to individual Mortgage
Loans from any title, hazard, or FHA insurance policy, VA guaranty, Primary
Mortgage Insurance Policy or other insurance policy covering such WMMSC Master
Serviced Loans, if required for the restoration or repair of the related
Mortgaged Property, may be deposited either in the WMMSC Escrow Account or a
Servicer Custodial Account. Such proceeds, if not required for the restoration
or repair of the related Mortgaged Property, shall be deposited in the related
Servicer Custodial Account, and shall be applied to the balances of the related
WMMSC Master Serviced Loans as payments of interest and principal. If the WMMSC
Master Servicer discovers that any Servicer Custodial Account or WMMSC Escrow
Account maintained by a WMMSC Servicer is not maintained with an institution
meeting the requirements of the first sentence of the definition of Eligible
Institution, then the WMMSC Master Servicer shall cause such account to be
transferred to an Eligible Institution within two Business Days of such
discovery.

            The WMMSC Master Servicer is hereby authorized to make withdrawals
from and to issue drafts against the WMMSC Servicer Custodial Accounts and the
WMMSC Escrow Accounts for the purposes required or permitted by this Agreement.

            Each WMMSC Servicer Custodial Account and each WMMSC Escrow Account
shall bear a designation clearly showing the respective interests of the
applicable WMMSC Servicer, as trustee, and of the WMMSC Master Servicer, in
substantially one of the following forms:

            With respect to the Servicer Custodial Account of a WMMSC Servicer:
(i) {Servicer's Name}, in trust for Washington Mutual Mortgage Securities Corp.
or (ii) {Servicer's Name}, as agent, trustee and/or bailee of principal and
interest custodial account for Washington Mutual Mortgage Securities Corp. and
its successors and assigns.

            With respect to the WMMSC Escrow Account: (i) {Servicer's Name}, in
trust for Washington Mutual Mortgage Securities Corp. or (ii) {Servicer's Name},
as agent, trustee and/or bailee of taxes and insurance custodial account for
Washington Mutual Mortgage Securities Corp. and its successors and assigns.

            The WMMSC Master Servicer hereby undertakes to assure remittance to
the Certificate Account of all amounts relating to the WMMSC Master Serviced
Loans that have been collected by any WMMSC Servicer and are due to the
Certificate Account pursuant to this Agreement.

            Funds held in the WMMSC Servicer Custodial Account and the WMMSC
Escrow Account may, at the WMMSC Master Servicer's option, be invested in one or
more Permitted Investments which shall in no event mature later than the
Business Day prior to the related Withdrawal Date (except that if such Permitted
Investments are obligations of or managed by the institution that maintains such
account, then such Permitted Investment shall mature not later than such
Withdrawal Date). The WMMSC Master Servicer shall bear any and all losses
incurred on any investments made with such funds and shall be entitled to retain
any gains realized on such investments as additional master servicing
compensation.

            Section 3.09 Collection of Mortgage Loan Payments; Master Servicer
Custodial Accounts and Certificate Account.

            (a) The Securities Administrator shall establish and maintain the
Certificate Account, which shall be deemed to consist of eight sub-accounts. The

            (b) Each Master Servicer shall establish and maintain a Master
Servicer Custodial Account, which shall be an Eligible Account. Each Master

            If a Master Servicer shall deposit any amount not required to be

Custodial Accounts shall be held by the Master Servicers in trust for the
Certificateholders until disbursed in accordance with this Agreement or
withdrawn in accordance with Section 3.11.

            (e) Each institution at which the WF Master Servicer Custodial

            (f) Each institution at which the Certificate Account is maintained

of the Master Servicer Custodial Accounts and the Certificate Account shall be
evidenced by a certification substantially in the form of Exhibit F hereto.

            Section 3.10 Access to Certain Documentation and Information
Regarding the Mortgage Loans.

            The WF Master Servicer shall afford and shall enforce the obligation
of the WF Servicers to afford and the WMMSC Master Servicer shall afford and
shall enforce the obligation of the WMMSC Servicers to afford, the Securities
Administrator and the Trustee reasonable access to all records and documentation
regarding the Mortgage Loans and all accounts, insurance information and other
matters relating to this Agreement, such access being afforded without charge,
but only upon reasonable request and during normal business hours at the office
designated by the related Master Servicer or the applicable Servicer.

            Section 3.11 Permitted Withdrawals from the Certificate Account, the
Master Servicer Custodial Accounts and the Servicer Custodial Accounts.

            (a) The WMMSC Master Servicer is authorized to make withdrawals from
time to time, from the WMMSC Master Servicer Custodial Account or the Servicer
Custodial Accounts established by any WMMSC Servicers of amounts deposited
therein in respect of the Certificates (and, to the extent applicable, to make
deposits of the amounts withdrawn), as follows:

            (i) To reimburse itself or the applicable WMMSC Servicer for WMMSC
      Advances made pursuant to Section 3.21 or a Servicing Contract, as
      applicable, such right to reimbursement pursuant to this paragraph (i)
      being limited to amounts received on particular Mortgage Loans (including,
      for this purpose, Insurance Proceeds and Liquidation Proceeds) which
      represent late recoveries of principal and/or interest respecting which
      any such WMMSC Advance was made;

            (ii) To reimburse itself or the applicable WMMSC Servicer for
      amounts expended by or for the account of the WMMSC Master Servicer
      pursuant to Section 3.15 or amounts expended by such WMMSC Servicer
      pursuant to the Servicing Contracts in connection with the restoration of
      property damaged by an Uninsured Cause or in connection with the
      liquidation of a Mortgage Loan;

            (iii) To pay to itself, with respect to the related WMMSC Master
      Serviced Loans, the WMMSC Master Servicing Fee to which it is entitled to
      pursuant to Section 3.18 (net of Compensating Interest reduced by Payoff
      Earnings and Payoff Interest) as to which no prior withdrawals from funds
      deposited by the WMMSC Master Servicer have been made;

            (iv) To reimburse itself or the applicable WMMSC Servicer for
      advances made with respect to related WMMSC Mortgage Loans (except for
      WMMSC Mortgage Loans purchased pursuant to a Purchase Obligation or
      pursuant to the second sentence of the third paragraph of Section 3.01(b))
      which the WMMSC Master Servicer has determined to be Nonrecoverable
      Advances, such reimbursement pursuant to this clause (iv) being made first
       from amounts received on the WMMSC Mortgage Loans in the same Loan Group
      as the Mortgage Loan in respect of which such Nonrecoverable Advance was
      made;

            (v) To pay itself any WMMSC Master Servicer Custodial Account
      Reinvestment Income;

            (vi) To reimburse itself for expenses incurred by and reimbursable
      to it pursuant to Section 7.03;

            (viii) To clear and terminate the WMMSC Master Servicer Custodial
      Account and following termination of this Agreement pursuant to Section
      10.01.

            If the WMMSC Master Servicer fails to remit the funds described in
Section 3.11(a)(vii) above to the Securities Administrator on the applicable
Remittance Date (not considering any cure period afforded to the WMMSC Master
Servicer for such remittance under Section 8.01(a)), the WMMSC Master Servicer
shall pay to the Securities Administrator, for its own account, interest accrued
on such funds at the prime rate as set forth in The Wall Street Journal from and
including the applicable Remittance Date to but excluding the day such funds are
paid to the Securities Administrator.

            Since, in connection with withdrawals pursuant to paragraphs (i) and
(ii), the WMMSC Master Servicer's entitlement thereto is limited to collections
or other recoveries on the related Mortgage Loan, the WMMSC Master Servicer or
the applicable WMMSC Servicer shall keep and maintain separate accounting for
each WMMSC Mortgage Loan, for the purpose of justifying any such withdrawals.

            (b) The Securities Administrator shall withdraw funds from the
Certificate Account to reimburse the Depositor for expenses incurred by it and
reimbursable pursuant to this Agreement, including but not limited to, Section
7.03, to pay itself and the Trustee any amounts due itself or the Trustee under
this Agreement (including, but not limited to, the Securities Administrator Fee
and all amounts provided for under Section 9.11, other than the amounts provided
for in the first sentence of Section 9.11) and for distributions to
Certificateholders in the manner specified in this Agreement. In addition, the
WF Master Servicer may from time to time make withdrawals from the WF Master
Servicer Custodial Account for the following purposes:

            (i) to pay to the WF Servicers (to the extent not previously
      retained by them), the Servicing Fee to which they are entitled pursuant
      to the Servicing Agreements and to pay itself any WF Master Servicer
      Custodial Account Reinvestment Income;

            (ii) [Reserved];

            (iii) to reimburse the WF Servicers (or, if applicable, itself or
      Trustee) for unreimbursed Advances made pursuant to the related Servicing
      Agreement (or in the case of itself or the Trustee, pursuant to Section
      3.21), such right of reimbursement pursuant to this clause (iii) being
      limited first to amounts received on the Mortgage Loans serviced by such
      WF Servicer in the related Loan Group in respect of which any such Advance
      was made and then limited to amounts received on all the Mortgage Loans
      serviced by such Servicer;

            (iv) to reimburse the WF Servicers (or, if applicable, itself or the
      Trustee) for any Nonrecoverable Advance previously made, such right of
      reimbursement pursuant to this clause (iv) being limited first to amounts
      received on the WF Master Serviced Loans in the same Loan Group as the
      Mortgage Loan(s) in respect of which such Nonrecoverable Advance was made
      and then limited to amounts received on all the Mortgage Loans serviced by
      such Servicer;

            (v) to reimburse the WF Servicers for Insured Expenses from the
      related Insurance Proceeds;

            (vi) to pay to the purchaser, with respect to each Mortgage Loan or
      REO Property that has been purchased pursuant to Section 2.02, 2.04 or
      3.15(g), all amounts received thereon after the date of such purchase;

            (vii) to reimburse itself for expenses incurred by it and
      reimbursable pursuant to this Agreement, including but not limited to,
      Section 7.03;

            (viii) to withdraw any amount deposited in the WF Master Servicer
      Custodial Account and not required to be deposited therein; and

            (ix) to clear and terminate the WF Master Servicer Custodial Account
      upon termination of this Agreement pursuant to Section 10.01.

      If a Master Servicer shall remit to the Securities Administrator any
      amount not required to be remitted, it may at any time direct the
      Securities Administrator to withdraw such amount from the Certificate
      Account, any provision herein to the contrary notwithstanding. Such
      direction may be accomplished by delivering an Officer's Certificate to
      the Securities Administrator which describes the amounts remitted in error
      to the Securities Administrator for deposit to the Certificate Account. In
      no event shall the Securities Administrator incur liability for
      withdrawals from the Certificate Account at the direction of either Master
      Servicer.

            (c) Each Servicer and each Master Servicer is authorized to make
withdrawals, from time to time, from the related Servicer Custodial Account or
related Master Servicer Custodial Account, (i) to pay to itself, with respect to
the related Mortgage Loans, the Servicing Fee and (ii) to reimburse itself for
expenses to the same extent that the WMMSC Master Servicer is authorized to make
withdrawals to reimburse the applicable WMMSC Servicer for expenses pursuant to
clauses (i), (ii) and (iv) of Section 3.11(a), in the case of clause (i) and
(ii) of this Section 3.11(c), to the extent no prior withdrawals of such amounts
have been made by the related Servicer or the related Master Servicer.

            (d) On each Distribution Date, funds on deposit in the Certificate
Account and deemed to be on deposit in the Group REMIC Sub-Accounts shall be
used to make payments on the Class 1-A-LR Certificate in respect of the Group
REMICs as provided in Sections 5.01 and 5.02. On each Distribution Date, funds
on deposit in the Certificate Account and deemed to be on deposit in the Pooling
REMIC Sub-Account shall be used to make payments on the Class 1-A-LR Certificate
in respect of the Pooling REMIC as provided in Sections 5.01 and 5.02. On each
Distribution Date, funds on deposit in the Certificate Account and deemed to be
on deposit in the Upper-Tier Certificate Sub-Account shall be used to make
payments on the Regular Certificates, the Class X-PO Certificates and the Class
15-PO Certificates and the Class 1-A-R Certificate as provided in Sections 5.01
and 5.02. The Certificate Account shall be cleared and terminated upon
termination of this Agreement pursuant to Section 10.01.

            Section 3.12 Maintenance of Hazard Insurance and Other Insurance.

            (a) For each WF Master Serviced Loan, the WF Master Servicer shall
enforce any obligation of the WF Servicers under the related Servicing
Agreements to maintain or cause to be maintained fire, flood and hazard
insurance with extended coverage customary in the area where the Mortgaged
Property is located in accordance with the related Servicing Agreements. It is
understood and agreed that such insurance provided for in this Section 3.12
shall be with insurers meeting the eligibility requirements set forth in the
applicable Servicing Agreement and that no earthquake or other additional
insurance is to be required of any Mortgagor or to be maintained on property
acquired in respect of a defaulted loan, other than pursuant to such applicable
laws and regulations as shall at any time be in force and as shall require such
additional insurance.

            Pursuant to Sections 3.08 and 3.09, any amounts collected by the WF
Master Servicer, or by any WF Servicer, under any insurance policies (other than
amounts to be applied to the restoration or repair of the property subject to
the related Mortgage or released to the Mortgagor in accordance with the
applicable Servicing Agreement) shall be deposited into the applicable Master
Servicer Custodial Account, subject to withdrawal pursuant to Sections 3.09 and
3.11. Any cost incurred by the WF Master Servicer or any WF Servicer in
maintaining any such insurance if the Mortgagor defaults in its obligation to do
so shall be added to the amount owing under the WF Master Serviced Loan where
the terms of the WF Master Serviced Loan so permit; provided, however, that the
addition of any such cost shall not be taken into account for purposes of
calculating the distributions to be made to Certificateholders and shall be
recoverable by the WF Master Servicer or such WF Servicer pursuant to Sections
3.08 and 3.09.

            (b) WMMSC Master Servicer shall cause to be maintained for each
WMMSC Master Serviced Loan (other than a Cooperative Loan) fire insurance with
extended coverage in an amount which is not less than the original principal
balance of such WMMSC Master Serviced Loan, except in cases approved by the
WMMSC Master Servicer in which such amount exceeds the value of the improvements
to the Mortgaged Property. The WMMSC Master Servicer shall also require fire
insurance with extended coverage in a comparable amount on property acquired
upon foreclosure, or deed in lieu of foreclosure, of any WMMSC Master Serviced
Loan (other than a Cooperative Loan). Any amounts collected under any such
policies (other than amounts to be applied to the restoration or repair of the
related Mortgaged Property) shall be deposited into the related Servicer
Custodial Account, subject to withdrawal pursuant to Sections 3.09 and 3.11. Any
unreimbursed costs incurred in maintaining any insurance described in this
Section 3.12 shall be recoverable as an Advance by the WMMSC Master Servicer
from the WMMSC Master Servicer Custodial Account or the Certificate Account.
Such insurance shall be with insurers approved by the WMMSC Master Servicer and
FNMA or FHLMC. Other additional insurance may be required of a Mortgagor, in
addition to that required pursuant to such applicable laws and regulations as
shall at any time be in force and as shall require such additional insurance.
Where any part of any improvement to the Mortgaged Property (other than a
Mortgaged Property secured by a Cooperative Loan) is located in a federally
designated special flood hazard area and in a community which participates in
the National Flood Insurance Program at the time of origination of the related
WMMSC Master Serviced Loan, the WMMSC Master Servicer shall cause flood
insurance to be provided. The hazard insurance coverage required by this Section
3.12 may be met with blanket policies providing protection equivalent to
individual policies otherwise required. The WMMSC Master Servicer shall be
responsible for paying any deductible amount on any such blanket policy. The
WMMSC Master Servicer agrees to present, or cause to be presented, on behalf of
and for the benefit of the Trust, claims under the hazard insurance policy
respecting any WMMSC Master Serviced Loan, and in this regard to take such
reasonable actions as shall be necessary to permit recovery under such policy.

            Section 3.13 Presentment of Claims and Collection of Proceeds.

            The WF Master Servicer shall (to the extent provided in the
applicable Servicing Agreement) cause the related WF Servicer to, prepare and
present on behalf of the Trustee and the Certificateholders all claims under the
Insurance Policies and take such actions (including the negotiation, settlement,
compromise or enforcement of the insured's claim) as shall be necessary to
realize recovery under such policies. Any proceeds disbursed to the WF Master
Servicer (or disbursed to a WF Servicer and remitted to the WF Master Servicer)
in respect of such policies, bonds or contracts shall be promptly deposited in
the WF Master Servicer Custodial Account upon receipt, except that any amounts
realized that are to be applied to the repair or restoration of the related
Mortgaged Property as a condition precedent to the presentation of claims on the
related Mortgage Loan to the insurer under any applicable Insurance Policy need
not be so deposited (or remitted).

            Section 3.14 Enforcement of Due-On-Sale Clauses; Assumption
Agreements.

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

            (b) When any Mortgaged Property securing a WMMSC Master Serviced
Loan is about to be conveyed by the Mortgagor, the WMMSC Master Servicer shall,
to the extent it has knowledge of such prospective conveyance and prior to the
time of the consummation of such conveyance, exercise on behalf of the Trust the
Trust's rights to accelerate the maturity of such WMMSC Master Serviced Loan, to
the extent that such acceleration is permitted by the terms of the related
Mortgage Note, under any "due-on-sale" clause applicable thereto; provided,
however, that the WMMSC Master Servicer shall not exercise any such right if the
due-on-sale clause, in the reasonable belief of the WMMSC Master Servicer, is
not enforceable under applicable law or if such exercise would result in
non-coverage of any resulting loss that would otherwise be covered under any
insurance policy. In the event the WMMSC Master Servicer is prohibited from
exercising such right, the WMMSC Master Servicer is authorized to take or enter
into an assumption and modification agreement from or with the Person to whom a
Mortgaged Property has been or is about to be conveyed, pursuant to which such
Person becomes liable under the Mortgage Note and, unless prohibited by
applicable state law or unless the Mortgage Note contains a provision allowing a
qualified borrower to assume the Mortgage Note, the Mortgagor remains liable
thereon; provided that the WMMSC Master Serviced Loan shall continue to be
covered (if so covered before the WMMSC Master Servicer enters such agreement)
by any related Primary Mortgage Insurance Policy. The WMMSC Master Servicer is
also authorized to enter into a substitution of liability agreement with such
Person, pursuant to which the original Mortgagor is released from liability and
such Person is substituted as Mortgagor and becomes liable under the Mortgage
Note. The WMMSC Master Servicer shall not enter into any substitution or
assumption with respect to a WMMSC Master Serviced Loan if such substitution or
assumption shall (i) both constitute a "significant modification" effecting an
exchange or reissuance of such WMMSC Master Serviced Loan under the Code (or
Treasury regulations promulgated thereunder) and cause any REMIC created
hereunder to fail to qualify as a REMIC under the REMIC Provisions, (ii) cause
the imposition of any tax on "prohibited transactions" or "contributions" after
the startup day under the REMIC Provisions or (iii) change the applicable
Mortgage Interest Rate. The WMMSC Master Servicer shall notify the Trustee that
any such substitution or assumption agreement has been completed and shall
forward to the related Custodian the original copy of such substitution or
assumption agreement and other documents and instruments constituting a part
thereof. In connection with any such assumption or substitution agreement, the
terms of the related Mortgage Note shall not be changed. Any fee collected by
the applicable WMMSC Servicer for entering into an assumption or substitution of
liability agreement shall be retained by such WMMSC Servicer as additional
servicing compensation.

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

            Section 3.15 Realization Upon Defaulted Mortgage Loans; REO
Property.

            (a) The WF Master Servicer shall cause each WF Servicer (to the
extent required under the related Servicing Agreement) to foreclose upon or
otherwise comparably convert the ownership of Mortgaged Properties securing such
of the WF Master Serviced Loans as come into and continue in default and as to
which no satisfactory arrangements can be made for collection of delinquent
payments, all in accordance with the applicable Servicing Agreement.

            (b) The WMMSC Master Servicer shall foreclose upon or otherwise
comparably convert, or cause to be foreclosed upon or comparably converted, the
ownership of any Mortgaged Property securing a WMMSC Master Serviced Loan which
comes into and continues in default and as to which no satisfactory arrangements
can be made for collection of delinquent payments pursuant to Section 3.01. In
lieu of such foreclosure or other conversion, and taking into consideration the
desirability of maximizing net Liquidation Proceeds after taking into account
the effect of Insurance Proceeds upon Liquidation Proceeds, the WMMSC Master
Servicer may, to the extent consistent with prudent mortgage loan servicing
practices, accept a payment of less than the outstanding Stated Principal
Balance of a delinquent WMMSC Master Serviced Loan in full satisfaction of the
indebtedness evidenced by the related Mortgage Note and release the lien of the
related Mortgage upon receipt of such payment. The WMMSC Master Servicer shall
not foreclose upon or otherwise comparably convert a Mortgaged Property if the
WMMSC Master Servicer is aware of evidence of toxic waste, other hazardous
substances or other evidence of environmental contamination thereon and the
WMMSC Master Servicer determines that it would be imprudent to do so. In
connection with such foreclosure or other conversion, the WMMSC Master Servicer
shall cause to be followed such practices and procedures as it shall deem
necessary or advisable and as shall be normal and usual in general mortgage
servicing activities. The foregoing is subject to the provision that, in the
case of damage to a Mortgaged Property from an Uninsured Cause, the WMMSC Master
Servicer shall not be required to advance its own funds towards the restoration
of the property unless it shall be determined in the sole judgment of the WMMSC
Master Servicer, (i) that such restoration will increase the proceeds of
liquidation of the Mortgage Loan to Certificateholders after reimbursement to
itself for such expenses, and (ii) that such expenses will be recoverable to it
through Liquidation Proceeds. The WMMSC Master Servicer shall be responsible for
all other costs and expenses incurred by it in any such proceedings; provided,
however, that it shall be entitled to reimbursement thereof (as well as its
normal servicing compensation) as an Advance. The WMMSC Master Servicer shall
maintain information required for tax reporting purposes regarding any Mortgaged
Property securing a WMMSC Master Serviced Loan which is abandoned or which has
been foreclosed or otherwise comparably converted. The WMMSC Master Servicer
shall report such information to the Internal Revenue Service and the Mortgagor
in the manner required by applicable law.

            (c) With respect to any REO Property, the deed or certificate of
sale shall be taken in the name of the Trust for the benefit of the
Certificateholders, or its nominee, on behalf of the Certificateholders. The WF
Master Servicer shall enforce the obligation of the WF Servicers, to the extent
provided in the applicable Servicing Agreement, to (i) cause the name of the
Trust to be placed on the title to such REO Property and (ii) ensure that the
title to such REO Property references this Agreement. The WF Master Servicer
shall, to the extent provided in the applicable Servicing Agreement, cause the
applicable WF Servicer to sell any REO Property as expeditiously as possible and
in accordance with the provisions of this Agreement and the related Servicing
Agreement, as applicable. Pursuant to its efforts to sell such REO Property, the
WF Master Servicer shall cause the applicable Servicer to protect and conserve
such REO Property in the manner and to the extent required by the applicable
Servicing Agreement, subject to the REMIC Provisions. In the event that the
Trust Estate acquires any Mortgaged Property as aforesaid or otherwise in
connection with a default or imminent default on a WF Master Serviced Loan, the
WF Master Servicer shall enforce the obligation of the related WF Servicer to
dispose of such Mortgaged Property within the time period specified in the
applicable Servicing Agreement unless the WF Servicer shall have applied for and
received an extension of such period from the Internal Revenue Service, in which
case the Trust Estate may continue to hold such Mortgaged Property for the
period of such extension.

            In the event that the Trust acquires any real property (or personal
property incident to such real property) in connection with a default or
imminent default of a WMMSC Master Serviced Loan or any REO Property relating to
a WMMSC Master Serviced Loan, such property shall be disposed of by the WMMSC
Master Servicer as soon as practicable in a manner that, consistent with prudent
mortgage loan servicing practices, maximizes the net present value of the
recovery to the Trust, but in any event within three years after its acquisition
by the WMMSC Master Servicer for the Trust (such period, the "REO Disposition
Period") unless the WMMSC Master Servicer provides to the Trustee and the
Securities Administrator an Opinion of Counsel to the effect that the holding by
the Trust of such Mortgaged Property subsequent to three years after its
acquisition will not result in the imposition of taxes on "prohibited
transactions" of the Trust as defined in Section 860F of the Code or under the
law of any state in which real property securing a WMMSC Master Serviced Loan
owned by the Trust is located or cause the applicable REMIC to fail to qualify
as a REMIC for federal income tax purposes or for state tax purposes under the
laws of any state in which real property securing a WMMSC Master Serviced Loan
owned by the Trust is located at any time that any Certificates are outstanding.
The WMMSC Master Servicer shall either itself or through an agent selected by
the WMMSC Master Servicer protect and conserve such property in the same manner
and to such extent as is customary in the locality where such property is
located and may, incident to its conservation and protection of the assets of
the Trust, rent the same, or any part thereof, as the WMMSC Master Servicer
deems to be in the best interest of the WMMSC Master Servicer and the Trust for
the period prior to the sale of such property. Additionally, the WMMSC Master
Servicer shall perform the tax withholding and shall file information returns
with respect to the receipt of mortgage interests received in a trade or
business, the reports of foreclosures and abandonments of any Mortgaged Property
and the information returns relating to cancellation of indebtedness income with
respect to any Mortgaged Property required by Sections 6050H, 6050J and 6050P,
respectively, of the Code. Such reports shall be in form and substance
sufficient to meet the reporting requirements imposed by Sections 6050H, 6050J
and 6050P of the Code.

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

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

            (f) The Liquidation Proceeds from the final disposition of the REO
Property, net of any payment to the applicable WF Servicer as provided above
shall be deposited in the related Servicer Custodial Account on or prior to the
Determination Date in the month following receipt thereof and be remitted by
wire transfer in immediately available funds to the related WF Servicer for
deposit into the related Servicer Custodial Account.

            Notwithstanding any other provision of this Agreement, neither
Master Servicer shall permit any Mortgaged Property acquired by the Trust to be
rented (or allowed to continue to be rented) or otherwise used for the
production of income by or on behalf of the Trust in such a manner or pursuant
to any terms that would (i) cause such Mortgaged Property to fail to qualify as
"foreclosure property" within the meaning of Section 860G(a)(8) of the Code,
(ii) result in the receipt by any REMIC if any "income from non-permitted
assets" within the meaning of Section 860F(a)(2)(B) of the Code or any "net
income from foreclosure property" which is subject to taxation under the REMIC
Provisions or (iii) subject any REMIC created hereunder to the imposition of any
federal, state or local income taxes on the income earned from such Mortgaged
Property under Section 860G(c) of the Code or otherwise, unless the related
Master Servicer or related Servicer, as applicable, has agreed to indemnify and
hold harmless the Trust with respect to the imposition of any such taxes.

            Notwithstanding any other provision of this Agreement, the Master
Servicers and the Securities Administrator, as applicable, shall comply with all
federal withholding requirements with respect to payments to Certificateholders
of interest or original issue discount that the Master Servicers or the
Securities Administrator reasonably believes are applicable under the Code. The
consent of Certificateholders shall not be required for any such withholding.
Without limiting the foregoing, the related Master Servicer agrees that it will
not withhold with respect to payments of interest or original issue discount in
the case of a Certificateholder that has furnished or caused to be furnished an
effective Form W-8 or an acceptable substitute form or a successor form and who
is not a "10 percent shareholder" within the meaning of Code Section
871(h)(3)(B) or a "controlled foreign corporation" described in Code Section
881(c)(3)(C) with respect to the Trust or the Depositor. In the event the
Securities Administrator withholds any amount from interest or original issue
discount payments or advances thereof to any Certificateholder pursuant to
federal withholding requirements, the Securities Administrator shall indicate
the amount withheld to such Certificateholder.

            (g) On the 2nd Business Day prior to the related Distribution Date,
the WF Master Servicer shall notify the Depositor of any WF Master Serviced Loan
which is 180 days or more delinquent. The Depositor shall be entitled, at its
option, to repurchase any such delinquent WF Master Serviced Loan from the Trust
Estate if in the Depositor's judgment, the default is not likely to be cured by
the Mortgagor. 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 through the last day of the month in which such
repurchase occurs. The Depositor shall notify the related WF Servicer and the WF
Master Servicer of its intent to repurchase such Mortgage Loan. Upon the receipt
of such purchase price, the WF Master Servicer shall provide to the Trustee the
notification required by Section 3.16 and the Trustee or the Custodian shall
promptly release to the Depositor the Mortgage File relating to the Mortgage
Loan being repurchased.
