                          POOLING AND SERVICING AGREEMENT

            THIS POOLING AND SERVICING AGREEMENT, dated December 28, 2005, is
hereby executed by and among BANC OF AMERICA FUNDING CORPORATION, as depositor
(together with its permitted successors and assigns, the "Depositor"), WELLS
FARGO BANK, N.A., as master servicer (together with its permitted successors and
assigns, in such capacity, the "Master Servicer") and as securities
administrator (together with its permitted successors and assigns, in such
capacity, the "Securities Administrator"), and WACHOVIA BANK, NATIONAL
ASSOCIATION, as trustee (together with its permitted successors and assigns, the
"Trustee").

                        W I T N E S S E T H   T H A T:

            In consideration of the mutual agreements herein contained, the
Depositor, the Master Servicer, the Securities Administrator and the Trustee
agree as follows:

                              PRELIMINARY STATEMENT

            In exchange for the Certificates, the Depositor hereby conveys the
Trust Estate to the Trustee to create the Trust. The Trust Estate for federal
income tax purposes shall be treated as three real estate mortgage investment
conduits (the "Upper-Tier REMIC," the "Middle-Tier REMIC" and the "Lower-Tier
REMIC," respectively, and each a "REMIC"). The Uncertificated Lower-Tier
Interests will represent the "regular interests" and the Class LR Interest shall
be the "residual interest" in the Lower-Tier REMIC for purposes of the REMIC
Provisions. The Uncertificated Lower-Tier Interests shall constitute the assets
of the Middle-Tier REMIC. The Uncertificated Middle-Tier Interests shall
constitute the "regular interests" and the Class MR Interest shall be the
"residual interest" in the Middle-Tier REMIC. The Uncertificated Middle-Tier
Interests shall constitute the assets of the Upper-Tier REMIC. The Senior
Certificates (other than the Class 1-A-R Certificate, the Class CB-IO
Certificates, the Class X-PO Certificates and the rights of the Class 1-A-1 and
Class 2-A-1 Certificates to receive amounts from the related Reserve Fund), the
Components and the Class B Certificates are referred to collectively as the
"Regular Certificates" and shall constitute "regular interests" in the
Upper-Tier REMIC for purposes of the REMIC Provisions. The Class UR Interest
shall be the "residual interest" in the Upper-Tier REMIC for purposes of the
REMIC Provisions. The Class 1-A-R Certificate shall represent beneficial
ownership of the Class LR Interest, the Class MR Interest and the Class UR
Interest. The portion of the Trust Estate consisting of the Reserve Funds, the
Yield Maintenance Agreements and the rights of the Class 1-A-1 and Class 2-A-1
Certificates to receive amounts from the related Reserve Fund shall not be
assets of any REMIC created hereunder, but rather shall be assets of the Grantor
Trust. The "latest possible maturity date" for federal income tax purposes of
all interests created hereby will be the REMIC Certificate Maturity Date.

            The following table sets forth characteristics of the Certificates
and the Components, together with the minimum denominations and integral
multiples in excess thereof in which the Classes of Certificates shall be
issuable:

                        ORIGINAL ISSUANCE OF CERTIFICATES

      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 and the related Mortgage Files,
including all interest and principal received on or with respect to the Mortgage

Mortgage Loans on or before the Cut-off Date) and the Depositor's rights under
the Mortgage Loan Purchase Agreement, including the rights of the Depositor as
assignee of the Seller with respect to the Seller's rights under the Servicing

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

effective November 27, 2003, (ii) the New Mexico Home Loan Protection Act

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
      _______________________, without recourse," with all necessary intervening
      endorsements showing a complete chain of endorsements (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);

            (ii) except as provided below and for each Mortgage Loan that is not
      a MERS Mortgage Loan, the original Mortgage with evidence of recording

      Loans and either language indicating that the Mortgage Loan is a MOM Loan
      or if the Mortgage Loan was not a MOM Loan at origination, the original
      Mortgage and the assignment thereof to MERS, with evidence of recording
      indicated thereon, or a copy of the Mortgage certified by the public
      recording office in which such Mortgage has been recorded;

      recorded or, if the original Assignment of Mortgage has not been returned
      from the applicable public recording office, a photocopy of the original
      Assignment of Mortgage, together with a certificate of the Seller
      certifying that the original Assignment of Mortgage has been delivered for
      recording in the appropriate public recording office of the jurisdiction
      in which the Mortgaged Property is located;

            (iv) originals, or copies thereof certified by the public recording
      office in which such documents have been recorded, of each assumption,
      extension, modification, written assurance or substitution agreements, if
      applicable, or if the original of such document has not been returned from
      the applicable public recording office, a photocopy of such original
      document together with certificate of the Servicer certifying the original
      of such document has been delivered for recording in the appropriate

      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

      recordation;

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

            (ix) if the Mortgage Note or Mortgage or any other material document

      instrument that authorized and empowered such person to sign bearing
      evidence that such instrument has been recorded, if so required in the
      appropriate jurisdiction where the Mortgaged Property is located (or, in
      lieu thereof, a duplicate or conformed copy of such instrument, together
      with a certificate of receipt from the recording office, certifying that
      such copy represents a true and complete copy of the original and that
      such original has been or is currently submitted to be recorded in the
      appropriate governmental recording office of the jurisdiction where the
      Mortgaged Property is located), or if the original power of attorney or
      other such instrument has been delivered for recording in the appropriate
      public recording office of the jurisdiction in which the Mortgaged
      Property is located; and

            (x) for each Mortgage Loan secured by Cooperative Stock, the

      relating to such stock certificate executed in blank; (C) the Recognition
      Agreement in substantially the same form as standard a "AZTECH" form; and
      (D) the executed UCC-1 financing statement with evidence of recording
      thereon and a filed UCC-3 financing statements.

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, extension, modification, written assurance or substitution
agreements, if any, or (D) the original policy of title insurance, 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 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 Custodian on
behalf of the Trustee, 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 (1) 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 an Officer's Certificate to such effect to the Trustee. The Depositor
shall forward or cause to be forwarded to the Custodian, on behalf of the
Trustee, (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, or the Servicer to the Custodian on
the Trustee's behalf. 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 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.

            With respect to each Mortgage Loan, as promptly as practicable
subsequent to such transfer and assignment, the Master Servicer shall (except
for any MERS Mortgage Loans) enforce the obligations of the Servicer pursuant to
the 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 Servicing Agreement and (II) if
applicable, 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 Custodian, except that, with respect to any Assignment of a
Mortgage as to which the Servicer has not received the information required to
prepare such assignment in recordable form, the 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 Servicing Agreement.

            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.
Exhibit J attached hereto sets forth the list of all states where recordation is
required by any Rating Agency to obtain the initial ratings of the Certificates.
The Securities Administrator and the Trustee may rely and shall be protected in
relying upon the information contained in such Exhibit J.

            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 Custodian on the Trustee's behalf, will cause the Servicer to remit to the
Master Servicer for deposit in the Master Servicer Custodial Account 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 Custodian of the Mortgage Loans. Subject to
the provisions of the following paragraph and pursuant to the Custodial
Agreement, the Custodian will declare that it holds and will hold the documents
referred to in Section 2.01 and the other documents delivered to it 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 cause the Custodian to deliver to the Depositor and
the Master Servicer a certification in the form attached hereto as Exhibit K
(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 listed on the Mortgage Loan
Schedule.

            Within 90 days after the execution and delivery of this Agreement,
the Custodian, on behalf of the Trustee, will review the Mortgage Files in such
Person's possession, and shall deliver to the Depositor and the Master Servicer
a certification in the form attached hereto as Exhibit L (the "Final
Certification") to the effect that, as to each Mortgage Loan 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 Custodian may conclusively rely on the purported genuineness of
any such document and any signature thereon.

            If, in the course of such review, the 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 or if the Depositor, the
Master Servicer, the Trustee, the Custodian or the Securities Administrator
discovers a breach by the Servicer or the Seller of any representation, warranty
or covenant under the Servicing Agreement or the Mortgage Loan Purchase
Agreement in respect of any Mortgage Loan and such breach materially adversely
affects the value of, or the interest of the Certificateholders in, the related
Mortgage Loan (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), then such party shall promptly so notify the Master
Servicer, the Seller, the Servicer and the Depositor of such failure to meet the
requirements of Section 2.01 or of such breach and request that the Servicer or
the Seller, as applicable, deliver such missing documentation or cure such
defect or breach within 90 days of its discovery or its receipt of notice of any
such failure to meet the requirements of Section 2.01 or of such breach. If the
Seller or the Servicer, as applicable, does not deliver such missing document or
cure such defect or breach in all material respects during such period, the
Trustee shall enforce the Servicer's or Seller's obligation (or SunTrust Bank's
obligation, to the extent the Seller fails to perform its obligations under the
Mortgage Loan Purchase Agreement), as the case may be, under the Servicing
Agreement or the Mortgage Loan Purchase Agreement, as applicable, and cause the
Servicer or Seller (or SunTrust Bank, to the extent the Seller fails to perform
its obligations under the Mortgage Loan Purchase Agreement), as applicable, to
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 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.

            Notwithstanding any contrary provision of this Agreement, no
substitution pursuant to this Section 2.02 shall be made more than 90 days after
the Closing Date unless the Depositor delivers to the Securities Administrator
an Opinion of Counsel, which Opinion of Counsel shall not be at the expense of
the Trustee, the Securities Administrator or the Trust Estate, addressed to the
Trustee and the Securities Administrator, to the effect that such substitution
will not (i) result in the imposition of the tax on "prohibited transactions" on
any REMIC created hereunder or contributions after the Start-up Day, as defined
in Sections 860F(a)(2) and 860G(d) of the Code, respectively or (ii) cause any
REMIC created hereunder to fail to qualify as a REMIC at any time that any
Certificates are outstanding.

            It is understood that the scope of the 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 Mortgage Loans identified in the Mortgage Loan
Schedule based solely upon the review of items (i) and (xi) in the definition of
Mortgage Loan Schedule. The Custodian shall not 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 the Servicer or the Seller, the Trustee shall enforce the rights of
the Trust under the Servicing Agreement 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 Mortgage Loans set forth in
the 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 Mortgage Loan set forth in clauses
(k) or (o) of Section 3 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 (or
SunTrust Bank, to the extent the Seller fails to perform its obligations under
the Mortgage Loan Purchase Agreement) for all costs or damages incurred by the
Trust as a result of the violation of such law (such amount, the "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 Servicer does not so reimburse the Trust. It is understood and agreed
that, except for any indemnification provided in the Servicing Agreement and the
payment of any Reimbursement Amount, the obligation of the Servicer or the
Seller (or SunTrust Bank, to the extent the Seller fails to perform its
obligations under the Mortgage Loan Purchase Agreement) to cure or to repurchase
any Mortgage 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 the Servicer or the Seller
(or SunTrust Bank, to the extent the Seller fails to perform its obligations
under the Mortgage Loan Purchase Agreement) 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
Mortgage 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 Master Servicer or the
Trustee that the substance of such representation or warranty is inaccurate and
such inaccuracy materially and adversely affects the value of, or the interest
of the Certificateholders in, the related Mortgage Loan then, notwithstanding
the Seller's lack of knowledge with respect to the substance of such
representation or warranty being inaccurate at 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 Mortgage Loans set forth in the Mortgage Loan Purchase Agreement
shall survive delivery of the Mortgage Files to the Custodian on the Trustee's
behalf 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 (or SunTrust Bank, to the extent the
Seller fails to perform its obligations under the Mortgage Loan Purchase
Agreement) set forth in this Section 2.02 to cure, substitute for or repurchase
a Mortgage 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 the Servicer with respect to
the Mortgage Loans in the Servicing Agreement, which have been assigned to the
Trustee hereunder, were made as of the date specified in the Servicing
Agreement. To the extent that any fact, condition or event with respect to a
Mortgage Loan constitutes a breach of both (i) a representation or warranty of
the Servicer under the 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 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 Servicer in the Servicing Agreement, without regard to
whether the 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 Mortgage Loans (except as set
forth in Section 2.04) under any circumstances.

            With respect to each Substitute Mortgage Loan the Seller (or
SunTrust Bank, to the extent the Seller fails to perform its obligations under
the Mortgage Loan Purchase Agreement) shall deliver to the Custodian, 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. 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 Seller
(or SunTrust Bank, to the extent the Seller fails to perform its obligations
under the Mortgage Loan Purchase Agreement) or the Servicer has substituted a
Substitute Mortgage Loan.

            The 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 Master Servicer shall deliver the amended
Mortgage Loan Schedule to the Securities Administrator, the Trustee and the
Custodian. Upon such substitution of a Mortgage Loan by the Seller (or SunTrust
Bank, to the extent the Seller fails to perform its obligations under the
Mortgage Loan Purchase Agreement) or the Servicer, each Substitute Mortgage Loan
shall be subject to the terms of this Agreement in all respects, the Seller (or
SunTrust Bank, to the extent the Seller fails to perform its obligations under
the Mortgage Loan Purchase Agreement) 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 and the Servicer shall be deemed to have
made to the Trustee with respect to such Substitute Mortgage Loan, as of the
date of substitution, the mortgage loan representations and warranties made
pursuant to the Servicing Agreement. Upon any such substitution and the deposit
to the 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 direct the Custodian to release the
Mortgage File relating to such Defective Mortgage Loan to the applicable Person
and shall execute and deliver at such Person's direction such instruments of
transfer or assignment prepared by such Person, without recourse, as shall be
necessary to vest title in such Person 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 SunTrust Bank, to the extent
the Seller fails to perform its obligations under the Mortgage Loan Purchase
Agreement) or the Servicer 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 such
Person 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 such Person (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 such Person to the Master Servicer for deposit to the Master
Servicer Custodial Account on or before the 18th day of the month succeeding the
calendar month during which the related Mortgage Loan is required to be
purchased or replaced hereunder.

            The Custodian shall retain possession and custody of each Mortgage
File in accordance with and subject to the terms and conditions set forth
herein. The Master Servicer shall cause to be promptly delivered to the
Custodian 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 Master Servicer's possession
from time to time.

            The Custodian 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 has been provided in lieu of a title policy
for any Mortgage Loan, the Custodian shall only be responsible for confirming
that a title search or opinion of counsel has been provided for such Mortgage
Loan.

            The Securities Administrator is hereby directed to execute and
deliver, on behalf of the Trust, the Yield Maintenance Agreements.

      Section 2.03 Representations, Warranties and Covenants of the Master
Servicer. (a) The Master Servicer hereby makes the following representations and
warranties to the Depositor, the Securities Administrator and the Trustee, as of
the Closing Date:

            (i) The Master Servicer is a national banking association duly
      chartered and validly existing in good standing under the laws of the
      United States of America and has all licenses necessary to carry on its
      business as now being conducted and is licensed, qualified and in good
      standing in each of the states where a Mortgaged Property securing a
      Mortgage Loan is located if the laws of such state require licensing or
      qualification in order to conduct business of the type conducted by the
      Master Servicer. The Master Servicer has power and authority to execute
      and deliver this Agreement and to perform in accordance herewith; the
      execution, delivery and performance of this Agreement (including all
      instruments of transfer to be delivered pursuant to this Agreement) by the
      Master Servicer and the consummation of the transactions contemplated
      hereby have been duly and validly authorized. This Agreement, assuming due
      authorization, execution and delivery by the other parties hereto,
      evidences the valid, binding and enforceable obligation of the Master
      Servicer, subject to applicable law except as enforceability may be
      limited by (A) bankruptcy, insolvency, liquidation, receivership,
      moratorium, reorganization or other similar laws affecting the enforcement
      of the rights of creditors and (B) general principles of equity, whether
      enforcement is sought in a proceeding in equity or at law. All requisite
      corporate action has been taken by the Master Servicer to make this
      Agreement valid and binding upon the Master Servicer in accordance with
      its terms.

            (ii) No consent, approval, authorization or order is required for
      the transactions contemplated by this Agreement from any court,
      governmental agency or body, or federal or state regulatory authority
      having jurisdiction over the Master Servicer is required or, if required,
      such consent, approval, authorization or order has been or will, prior to
      the Closing Date, be obtained.

            (iii) The consummation of the transactions contemplated by this
      Agreement are in the ordinary course of business of the Master Servicer
      and will not result in the breach of any term or provision of the charter
      or by-laws of the Master Servicer or result in the breach of any term or
      provision of, or conflict with or 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 Master Servicer or
      its property is subject, or result in the violation of any law, rule,
      regulation, order, judgment or decree to which the Master Servicer or its
      property is subject.

            (iv) There is no action, suit, proceeding or investigation pending
      or, to the best knowledge of the Master Servicer, threatened against the
      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 Master Servicer, or in
      any material impairment of the right or ability of the Master Servicer to
      carry on its business substantially as now conducted or which would draw
      into question the validity of this Agreement or the Mortgage Loans or of
      any action taken or to be taken in connection with the obligations of the
      Master Servicer contemplated herein, or which would materially impair the
      ability of the Master Servicer to perform under the terms of this
      Agreement.

            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.

      Section 2.04 Representations and Warranties of the Depositor as to the
Mortgage Loans. 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 any 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 Custodian and shall inure to the benefit of the Certificateholders,
notwithstanding any restrictive or qualified endorsement or assignment.

            Upon discovery by any of the Depositor, the Master Servicer, the
Securities Administrator or the Trustee 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 value of,
or the interests of the Certificateholders in, the related Mortgage Loan, the
party discovering such breach shall give prompt written notice to the other
parties; 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 Depositor 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. The Purchase Price of any
repurchase described in this paragraph and the Substitution Adjustment Amount,
if any shall be remitted to the Master Servicer for deposit to the Master
Servicer Custodial Account. It is understood and agreed that, except with
respect to the second preceding sentence, the obligation of the Depositor 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.

      Section 2.05 Designation of Interests in the REMICs. The Depositor hereby
designates the Classes of Senior Certificates (other than the Class 1-A-R, Class
CB-IO and Class X-PO Certificates), the Components and the Classes of
Subordinate Certificates as "regular interests" and the Class UR Interest as the
single class of "residual interest" in the Upper-Tier REMIC for the purposes of
Code Sections 860G(a)(1) and 860G(a)(2), respectively. The Depositor hereby
further designates (i) the Uncertificated Middle-Tier Interests as classes of
"regular interests" and the Class MR Interest as the single class of "residual
interest" in the Middle-Tier REMIC and (ii) the Uncertificated Lower-Tier
Interests as classes of "regular interests" and the Class LR Interest as the
single class of "residual interest" in the Lower-Tier REMIC for the purposes of
Code Sections 860G(a)(1) and 860G(a)(2), respectively.

      Section 2.06 Designation of Start-up Day. The Closing Date is hereby
designated as the "start-up day" of each of the Upper-Tier REMIC, the
Middle-Tier REMIC and Lower-Tier REMIC within the meaning of Section 860G(a)(9)
of the Code.

      Section 2.07 REMIC Certificate Maturity Date. Solely for purposes of
satisfying Section 1.860G-1(a)(4)(iii) of the Treasury Regulations, the "latest
possible maturity date" of the regular interests in the Upper-Tier REMIC, the
Middle-Tier REMIC and the Lower-Tier REMIC is December 25, 2035.

      Section 2.08 Execution and Delivery of Certificates. The Securities
Administrator (i) acknowledges the issuance of and hereby declares that it holds
the Uncertificated Lower-Tier Interests on behalf of the Middle-Tier REMIC and
the Certificateholders and that it holds the Uncertificated Middle-Tier
Interests on behalf of the Upper-Tier REMIC and the Certificateholders and (ii)
has executed and delivered to or upon the order of the Depositor, in exchange
for the Mortgage Loans, Uncertificated Lower-Tier Interests and Uncertificated
Middle-Tier Interests, together with all other assets included in the definition
of "Trust Estate," receipt of which is hereby acknowledged, Certificates in
authorized denominations which, together with the Uncertificated Middle-Tier

                                  ARTICLE III

                       ADMINISTRATION AND MASTER SERVICING
                                OF MORTGAGE LOANS

      Section 3.01 Master Servicing of the Mortgage Loans. For and on
behalf of the Certificateholders, the Master Servicer shall supervise, monitor
and oversee the obligations of the Servicer to service and administer the
Mortgage Loans in accordance with the terms of the Servicing Agreement and shall
have full power and authority to do any and all things which it may deem
necessary or desirable in connection with such master servicing and
administration. In performing its obligations hereunder, the Master Servicer
shall act in a manner consistent with this Agreement, subject to the prior
sentence, and with Customary Servicing Procedures. Furthermore, the Master
Servicer shall oversee and consult with the Servicer as necessary from
time-to-time to carry out the Master Servicer's obligations hereunder, shall
receive, review and evaluate all reports, information and other data provided to
the Master Servicer by the Servicer and shall cause the Servicer to perform and
observe the covenants, obligations and conditions to be performed or observed by
the Servicer under the Servicing Agreement. The Master Servicer shall
independently monitor the Servicer's servicing activities with respect to each
Mortgage Loan, reconcile the results of such monitoring with such information
provided in the previous sentence on a monthly basis and coordinate corrective
adjustments to the Servicer's and the Master Servicer's records, and based on
such reconciled and corrected information, prepare the Master Servicer's
Certificate and any other information and statements required hereunder. The
Master Servicer shall reconcile the results of its Mortgage Loan monitoring with
the actual remittances of the Servicer to the Master Servicer Custodial Account
pursuant to the Servicing Agreement.

            Continuously from the date hereof until the termination of the
Trust, the Master Servicer shall enforce the obligations of the Servicer to
collect all payments due under the terms and provisions of the Mortgage Loans
when the same shall become due and payable to the extent such procedures shall
be consistent with the Servicing Agreement.

            The relationship of the Master Servicer (and of any successor to the
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.

      Section 3.02 Monitoring of Servicer. (a) The Master Servicer shall be
responsible for reporting to the Trustee, the Securities Administrator and the
Depositor the compliance by the Servicer with its duties under the Servicing
Agreement. In the review of the Servicer's activities, the Master Servicer may
rely upon an officer's certificate of the Servicer with regard to the Servicer's
compliance with the terms of the Servicing Agreement. In the event that the
Master Servicer, in its judgment, determines that the Servicer should be
terminated in accordance with the Servicing Agreement, or that a notice should
be sent pursuant to the Servicing Agreement with respect to the occurrence of an
event that, unless cured, would constitute grounds for such termination, the
Master Servicer shall notify the Depositor, the Securities Administrator and the
Trustee thereof and the Master Servicer shall issue such notice or take such
other action as it deems appropriate.

            (b) The Master Servicer, for the benefit of the Trustee and the
Certificateholders, shall enforce the obligations of the Servicer under the
Servicing Agreement, and shall, in the event that the Servicer fails to perform
its obligations in accordance with the Servicing Agreement, subject to the
preceding paragraph, terminate the rights and obligations of the Servicer
thereunder and act as successor Servicer of the related Mortgage Loans under the
Servicing Agreement or cause the Trustee to enter in to a new Servicing
Agreement with a successor Servicer selected by the Master 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 Servicer. Such enforcement,
including, without limitation, the legal prosecution of claims, termination of
the Servicing Agreement and the pursuit of other appropriate remedies, shall be
in such form and carried out to such an extent and at such time as the Master
Servicer, in its good faith business judgment, would require were it the owner
of the related Mortgage Loans. The Master Servicer 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 Mortgage Loans or (ii) from a specific recovery of costs,
expenses or attorneys fees against the party whom such enforcement is directed,
provided that the Master Servicer and the Trustee, as applicable, shall not be
required to prosecute or defend any legal action except to the extent that the
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 Master Servicer
or the Trustee, as applicable, related to any termination of the Servicer,
appointment of a successor Servicer or the transfer and assumption of servicing
by the Master Servicer or the Trustee, as applicable, with respect to the
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 Servicer as a result of an Event of Default
by the Servicer and (ii) all costs and expenses associated with the complete
transfer of servicing, including all servicing files and all servicing data and
the completion, correction or manipulation of such servicing data as may be
required by the successor Servicer to correct any errors or insufficiencies in
the servicing data or otherwise to enable the successor Servicer to service the
Mortgage Loans in accordance with the Servicing Agreement) are not fully and
timely reimbursed by the terminated Servicer, the 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 Master Servicer or the Trustee, as applicable, shall remit such amounts
that are reimbursed by the terminated Servicer to the Master Servicer Custodial
Account.

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

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

      Section 3.03 Fidelity Bond; Errors and Omissions Insurance. The Master
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. These policies must insure the Master Servicer
against losses resulting from dishonest or fraudulent acts committed by the
Master Servicer's personnel, any employees of outside firms that provide data
processing services for the Master 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 Servicer
from its duties and obligations as set forth in this Agreement. The minimum
coverage under any such bond and insurance policy shall be at least equal to the
corresponding amounts required by Fannie Mae in the Fannie Mae Servicing Guide
or by Freddie Mac in the Freddie Mac Sellers' & Servicers' Guide, as amended or
restated from time to time, or in an amount as may be permitted to the Master
Servicer by express waiver of Fannie Mae or Freddie Mac. In the event that any
such policy or bond ceases to be in effect, the Master Servicer 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 Master Servicer shall
provide, and the Master Servicer shall cause the Servicer to provide in
accordance with the 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 Master Servicer and the Servicer. In fulfilling such
request for access, the Master Servicer shall not be responsible to determine
the sufficiency of any information provided by the Servicer. Nothing in this
Section 3.04 shall limit the obligation of the Master Servicer and the Servicer
to observe any applicable law and the failure of the Master Servicer or the
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 Master Servicer shall not take, or permit the Servicer (to the
extent such action is prohibited under the 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 the Master Servicer
or the Servicer, would have been covered thereunder. The Master Servicer shall
use its best reasonable efforts to cause the Servicer (to the extent required
under the Servicing Agreement) to keep in force and effect (to the extent that
the Mortgage Loan requires the Mortgagor to maintain such insurance), primary
mortgage insurance applicable to each Mortgage Loan in accordance with the
provisions of this Agreement and the Servicing Agreement, as applicable. The
Master Servicer shall not, and shall not permit the Servicer (to the extent
required under the 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 Servicing
Agreement, as applicable.

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

      Section 3.06 Rights of the Depositor, the Securities Administrator
and the Trustee in Respect of the Master Servicer. The Depositor may, but is not
obligated to, enforce the obligations of the Master Servicer hereunder and may,
but is not obligated to, perform, or cause a designee to perform, any defaulted
obligation of the Master Servicer hereunder and in connection with any such
defaulted obligation to exercise the related rights of the Master Servicer
hereunder; provided that the 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
the Master Servicer and the Securities Administrator, the Trustee or the
Depositor shall not be obligated to supervise the performance of the Master
Servicer hereunder or otherwise.

      Section 3.07 Trustee to Act as Master Servicer. In the event the Master
Servicer or any successor master servicer shall for any reason no longer be the
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 the Master Servicer hereunder arising thereafter. Any
such assumption shall be subject to Sections 7.02 and 8.05.

            The predecessor Master Servicer at its expense shall, upon request
of the Trustee, deliver to the assuming party all master servicing documents and
records and an accounting of amounts collected or held by the Master Servicer,
and shall transfer control of the Master Servicer Custodial Account and any
investment accounts to the successor Master Servicer, and otherwise use its best
efforts to effect the orderly and efficient transfer of its rights and duties as
Master Servicer hereunder 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 Account and Escrow Account. The Master
Servicer shall enforce the obligation of the Servicer to establish and maintain
the Servicer Custodial Account in accordance with the 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 Servicing Agreement) of receipt all collections of principal and interest
on any Mortgage Loan and all collections with respect to any REO Property
received by the Servicer, including Principal Prepayments, Insurance Proceeds,
Liquidation Proceeds, Recoveries and Advances made from the Servicer's own funds
(less servicing compensation as permitted by the Servicing Agreement in the case
of the Servicer) and all other amounts to be deposited in the Servicer Custodial
Account. The Master Servicer is hereby authorized to make withdrawals from and
deposits to the Servicer Custodial Account for purposes required or permitted by
this Agreement.

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

      Section 3.09 Collection of Mortgage Loan Payments; Master Servicer
Custodial Account; Certificate Account and Reserve Funds. (a) Continuously from
the date hereof until the principal and interest on all Mortgage Loans are paid
in full, the Master Servicer shall enforce the obligations of the Servicer to
collect all payments due under the terms and provisions of the Mortgage Loans
when the same shall become due and payable to the extent such procedures shall
be consistent with the Servicing Agreement.

            (b) The Securities Administrator shall establish and maintain the
Certificate Account, which shall be deemed to consist of six sub-accounts and
into which the Master Servicer will deposit on or prior to 11:00 a.m. New York
time, on each Distribution Date (or, if the Securities Administrator is no
longer the same Person as, or an Affiliate of, the Master Servicer, the Business
Day preceding each Distribution Date) all amounts on deposit in the Master
Servicer Custodial Account for distribution to Certificateholders.

            (c) The Master Servicer shall establish and maintain the Master
Servicer Custodial Account, which shall be an Eligible Account and which may be
deemed to be a sub-account of the Certificate Account for so long as the Master
Servicer and the Securities Administrator are the same Person. The Master
Servicer shall, promptly upon receipt, deposit in the Master Servicer Custodial
Account and retain therein any amounts which are required to be deposited in the
Master Servicer Custodial Account by the Master Servicer.

            (d) On a daily basis within one (1) Business Day of receipt (except
as otherwise specifically provided herein), the Master Servicer shall deposit or
cause to be deposited the following payments and collections remitted to the
Master Servicer by the Servicer from the Servicer Custodial Account pursuant to
the Servicing Agreement or otherwise or received by the Master Servicer in
respect of the Mortgage Loans subsequent to the Cut-off Date (other than in
respect of principal and interest due on the Mortgage Loans on or before the
Cut-off Date) and the following amounts required to be deposited hereunder:

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

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

            (iii) (A) all Insurance Proceeds and Liquidation Proceeds, other
      than Insurance Proceeds to be (1) applied to the restoration or repair of
      the Mortgaged Property, (2) released to the Mortgagor in accordance with
      Customary Servicing Procedures or (3) required to be deposited to an
      Escrow Account pursuant to Section 3.08 and (B) any Insurance Proceeds
      released from an Escrow Account;

            (iv) any amount required to be deposited by the Master Servicer
      pursuant to Section 3.09(e) in connection with any losses on Permitted
       Investments with respect to the Master Servicer Custodial Account;

            (v) any amounts relating to REO Property required to be remitted by
      the Servicer;

            (vi) Periodic Advances made by the Servicer pursuant to the
      Servicing Agreement (or, if applicable, by the Master Servicer or the
      Trustee pursuant to Section 3.21) and any Compensating Interest paid by
      the Servicer pursuant to the Servicing Agreement;

            (vii) all Purchase Prices, all Substitution Adjustment Amounts and
      all Reimbursement Amounts to the extent received by the Servicer;

            (viii) any Recoveries; and

            (ix) any other amounts required to be deposited hereunder.

            If the Master Servicer shall deposit any amount not required to be
deposited, it may at any time withdraw such amount from the Master Servicer
Custodial Account, any provision herein to the contrary notwithstanding. All
funds required to be deposited in the Master Servicer Custodial Account shall be
held by the Master Servicer 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 Master Servicer Custodial Account
is maintained shall invest the funds therein as directed in writing by the
Master Servicer in Permitted Investments, which shall mature not later than the
Business Day next preceding the Distribution Date (except that if such Permitted
Investment is an obligation of the institution that maintains such account, then
such Permitted Investment shall mature not later than such Distribution Date)
and, in each case, shall not be sold or disposed of prior to its maturity. All
such Permitted Investments shall be made in the name of the Trustee, for the
benefit of the Certificateholders. All Master Servicer Custodial Account
Reinvestment Income shall be for the benefit of the Master Servicer as part of
its master servicing compensation and shall be remitted to the Master Servicer
monthly as provided herein. The amount of any losses realized in the Master
Servicer Custodial Account incurred in any such account in respect of any such
investments shall promptly be deposited by the Master Servicer from its own
funds in the Master Servicer Custodial Account.

            (f) Each institution at which the Certificate Account is maintained
shall invest the funds therein if directed in writing by the Securities
Administrator in Permitted Investments that are obligations of the institution
that maintains the Certificate Account, which shall mature on the Distribution
Date and shall not be sold or disposed of prior to its maturity. All such
Permitted Investments shall be made in the name of the Trustee, for the benefit
of the Certificateholders. All income and gains net of any losses realized since
the preceding Distribution Date from Permitted Investments of funds in the
Certificate Account shall be for the benefit of the Securities Administrator as
its compensation and the amount of any losses realized in the Certificate
Account in respect of any such Permitted Investments shall promptly be deposited
by the Securities Administrator from its own funds in the Certificate Account.

            (g) The Master Servicer shall give notice to the Depositor, the
Trustee, the Securities Administrator and the Rating Agencies of any proposed
change of location of the Master Servicer Custodial Account not later than 30
days after and not more that 45 days prior to any change thereof. The Securities
Administrator shall give notice to the Depositor, the Trustee, the Master
Servicer and the Rating Agencies of any proposed change of the location of the
Certificate Account maintained by the Securities Administrator not later than 30
days after and not more than 45 days prior to any change thereof. The creation
of the Master Servicer Custodial Account and the Certificate Account shall be
evidenced by a certification substantially in the form attached hereto as
Exhibit F.

            (h) The Securities Administrator shall designate each of the
Middle-Tier Certificate Sub-Account and the Upper-Tier Certificate Sub-Account
as a sub-account of the Certificate Account. On each Distribution Date (other
than the Final Distribution Date, if such Final Distribution Date is in
connection with a purchase of the assets of the Trust Estate by the Depositor),
the Securities Administrator shall, from funds available on deposit in the
Certificate Account, be deemed to deposit into the Middle-Tier Certificate
Sub-Account, the Lower-Tier Distribution Amount. The Securities Administrator
shall then immediately, from funds available in the Middle-Tier Certificate
Sub-Account, be deemed to deposit into the Upper-Tier Certificate Sub-Account,
the Middle-Tier Distribution Amount.

             (i) (i) The Securities Administrator shall establish and maintain
the Class 1-A-1 Reserve Fund and the Class 2-A-1 Reserve Fund, held in trust for
the benefit of the Holders of the Class 1-A-1 and Class 2-A-1 Certificates,
respectively, and Banc of America Securities LLC. The Securities Administrator
shall deposit in the applicable Reserve Fund on the date received by it, any
related Yield Maintenance Agreement Payment received from the Counterparty for
the related Distribution Date. Funds on deposit in the Reserve Funds shall
remain uninvested. On each Distribution Date, the Securities Administrator shall
withdraw from the applicable Reserve Fund any related Yield Maintenance
Agreement Payment received in respect of such Distribution Date and any Excess
Funds in such Reserve Fund and shall distribute such amounts to the Class 1-A-1
or Class 2-A-1 Certificates, as the case may be, in an amount up to the sum of
the applicable Yield Maintenance Amount for such Distribution Date and any
applicable Yield Maintenance Amount Shortfalls for prior Distribution Dates. Any
amounts remaining in the Class 1-A-1 or the Class 2-A-1 Reserve Fund on the date
on which the Class Certificate Balance of the Class 1-A-1 Certificates or Class
2-A-1 Certificates is reduced to zero (after payment of the related Yield
Maintenance Amount for such date and the amount of any related Yield Maintenance
Amount Shortfalls from previous Distribution Dates not yet paid) shall be
distributed by the Securities Administrator to Banc of America Securities LLC.

            (ii) The Securities Administrator shall account for the Reserve
      Funds and the Yield Maintenance Agreements and the rights with respect
      thereto as assets of the Grantor Trust and not as assets of any REMIC
       created pursuant to this Agreement. The beneficial owner of the Yield
      Maintenance Agreements and the Reserve Funds is Banc of America Securities
      LLC.

            (iii) Any amounts in the applicable Reserve Fund paid by the
      Securities Administrator pursuant to this Section 3.09(i) to the Class
      1-A-1 or Class 2-A-1 Certificates shall be accounted for by the Securities
      Administrator as amounts paid to the Class 1-A-1 or Class 2-A-1
      Certificates from the Grantor Trust. In addition, the Securities
      Administrator shall account for the right of the Class 1-A-1 and Class
      2-A-1 Certificates to receive amounts from the applicable Reserve Fund as
      rights in limited recourse interest rate cap contracts written by Banc of
      America Securities LLC in favor of the Class 1-A-1 and Class 2-A-1
      Certificates.

            (iv) For federal tax return and information reporting purposes, the
      right of the Holders of the Class 1-A-1 and Class 2-A-1 Certificates to
      receive payments under the applicable Yield Maintenance Agreement shall be
      assigned a value of zero as of the Closing Date.

      Section 3.10 Access to Certain Documentation and Information Regarding the
Mortgage Loans. The Master Servicer shall afford and shall enforce the
obligation of the Servicer 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 Master Servicer or the Servicer.

      Section 3.11 Permitted Withdrawals from the Certificate Account and the
Master Servicer Custodial Account. (a) The Securities Administrator shall
withdraw funds from the Certificate Account for distributions to
Certificateholders in the manner specified in this Agreement. In addition, the
Master Servicer may from time to time make withdrawals from the Master Servicer
Custodial Account for the following purposes:

            (i) to pay to the Servicer (to the extent not previously retained by
      it), the Servicing Fee to which it is entitled pursuant to the Servicing
      Agreement and to pay itself any Master Servicer Custodial Account
      Reinvestment Income;

            (ii) to pay to the Securities Administrator, the Custodian and the
      Trustee any amounts due to the Securities Administrator, the Custodian and
      the Trustee under this Agreement (including, but not limited to, all
      amounts provided for under Section 9.11, other than the amounts provided
      for in the first and second sentences of Section 9.11);

            (iii) to reimburse the Servicer (or, if applicable, itself or the
      Trustee) for unreimbursed Advances made pursuant to the 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 the
      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 the Servicer (or, if applicable, the Master Servicer or the
      Trustee) in respect of which any such Advance was made;

            (iv) to reimburse the Servicer (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 Mortgage 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 the
      Servicer (of, if applicable, the Master Servicer or the Trustee);

            (v) to reimburse the Servicer 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 or 2.04, all
      amounts received thereon after the date of such purchase;

             (vii) to reimburse itself or the Depositor for expenses incurred by
      either of them and reimbursable pursuant to this Agreement, including but
      not limited to, Section 3.02 and Section 7.03;

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

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

If the 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.

            (b) 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 and the Class 1-A-R
Certificate (in respect of the Class UR Interest) 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. For each
Mortgage Loan, the Master Servicer shall enforce any obligation of the Servicer
under the Servicing Agreement 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 Servicing Agreement. 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
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
Master Servicer, or by the 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
Servicing Agreement) shall be deposited into the Master Servicer Custodial
Account, subject to withdrawal pursuant to Sections 3.09 and 3.11. Any cost
incurred by the Master Servicer or the Servicer in maintaining any such
insurance if the Mortgagor defaults in its obligation to do so shall be added to
the amount owing under the Mortgage Loan where the terms of the Mortgage Loan so
permit; provided, however, that the addition of any such cost shall not be taken
into account for purposes of calculating the distributions to be made to
Certificateholders and shall be recoverable by the Master Servicer or the
Servicer pursuant to Sections 3.08 and 3.09.

      Section 3.13 Presentment of Claims and Collection of Proceeds. The
Master Servicer shall (to the extent provided in the Servicing Agreement) cause
the Servicer to prepare and present on behalf of the Trustee and the
Certificateholders all claims under the Insurance Policies and take such actions
(including the negotiation, settlement, compromise or enforcement of the
insured's claim) as shall be necessary to realize recovery under such policies.
Any proceeds disbursed to the Master Servicer (or disbursed to the Servicer and
remitted to the Master Servicer) in respect of such policies, bonds or contracts
shall be promptly deposited in the 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. To the extent provided in the Servicing Agreement and to the extent
Mortgage Loans contain enforceable due-on-sale clauses, the Master Servicer
shall cause the Servicer to enforce such clauses in accordance with the
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 Servicing Agreement, and, as a consequence, a Mortgage Loan is assumed, the
original Mortgagor may be released from liability in accordance with the
Servicing Agreement.

      Section 3.15 Realization Upon Defaulted Mortgage Loans; REO
Property.(a) The Master Servicer shall cause the Servicer (to the extent
required under the Servicing Agreement) to foreclose upon or otherwise
comparably convert the ownership of Mortgaged Properties securing such of the
Mortgage Loans as come into and continue in default and as to which no
satisfactory arrangements can be made for collection of delinquent payments, all
in accordance with the Servicing Agreement.

            (b) 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
Master Servicer shall enforce the obligation of the Servicer, to the extent
provided in the 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 Master Servicer shall, to the extent
provided in the Servicing Agreement, cause the Servicer to sell any REO Property
as expeditiously as possible and in accordance with the provisions of this
Agreement and the Servicing Agreement, as applicable. Pursuant to its efforts to
sell such REO Property, the Master Servicer shall cause the Servicer to protect
and conserve such REO Property in the manner and to the extent required by the
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 Mortgage Loan, the Master
Servicer shall enforce the obligation of the Servicer to dispose of such
Mortgaged Property within the time period specified in the Servicing Agreement,
but in any event within three years after the acquisition by the Servicer for
the Trust (such period, the "REO Disposition Period") unless (i) the Servicer
provides to the Trustee, the Master Servicer 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 Mortgage Loan owned by the Trust is located or cause any REMIC
created hereunder 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 Mortgage Loan owned by the Trust is located at any time that any
Certificates are outstanding or (ii) the 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.

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

            (d) The Servicer, upon the final disposition of any REO Property,
shall be entitled to reimbursement for any related unreimbursed 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 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.

            (e) The Liquidation Proceeds from the final disposition of the REO
Property, net of any payment to the Servicer as provided above shall be
deposited in the 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 Master Servicer for deposit into the Master
Servicer Custodial Account.

            Notwithstanding any other provision of this Agreement, the Master
Servicer shall not 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 created hereunder of any "income from
non-permitted assets" within the meaning of Section 860F(a)(2)(B) of the Code or
any "net income from foreclosure property" which is subject to taxation under
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 Master Servicer or the 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
Servicer 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 Servicer 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 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.

      Section 3.16 Trustee to Cooperate; Release of Mortgage Files. Upon the
payment in full of any Mortgage Loan, or the receipt by the Master Servicer or
the Servicer of a notification that payment in full will be escrowed in a manner
customary for such purposes, the Master Servicer or the Servicer will
immediately notify the Trustee and the Custodian by delivering, or causing to be
delivered, two copies (one of which will be returned to the Servicer with the
Mortgage File) of a Request for Release (which may be delivered in an electronic
format acceptable to the Custodian and the Trustee and the Master Servicer or
the Servicer). Upon receipt of such request, the Custodian shall within seven
(7) Business Days release the related Mortgage File to the Master Servicer or
the Servicer. The Trustee shall at the Master Servicer's or the Servicer's
direction execute and deliver to the Master Servicer or the Servicer the request
for reconveyance, deed of reconveyance or release or satisfaction of mortgage or
such instrument releasing the lien of the Mortgage relating to the Mortgage
Loan, in each case provided by the Master Servicer or the Servicer, together
with the Mortgage Note with written evidence of cancellation thereon. If the
Mortgage has been recorded in the name of MERS or its designee, the Master
Servicer shall enforce the Servicer's obligation under the Servicing Agreement
take all necessary action to reflect the release of the Mortgage on the records
of MERS. Expenses incurred in connection with any instrument of satisfaction or
deed of reconveyance shall be chargeable to the related Mortgagor of the
Mortgage Loan.

             From time to time and as shall be appropriate for the servicing or
foreclosure of any Mortgage Loan, including for such purpose collection under
any Primary Mortgage Insurance Policy, any policy of flood insurance, any
fidelity bond or errors or omissions policy, or for the purposes of effecting a
partial release of any Mortgaged Property from the lien of the Mortgage or the
making of any corrections to the Mortgage Note or the Mortgage or any of the
other documents included in the Mortgage File, the Custodian shall, upon
delivery to the Custodian of a Request for Release signed by a Master Servicing
Officer or a Servicing Officer, release the Mortgage File within seven (7)
Business Days to the Master Servicer or the Servicer. Subject to the further
limitations set forth below, the Master Servicer or the Servicer shall cause the
Mortgage Files so released to be returned to the Custodian when the need
therefor no longer exists, unless the Mortgage Loan is liquidated and the
proceeds thereof are deposited in the Servicer Custodial Account, in which case
the Servicer shall deliver to the Custodian a Request for Release, signed by a
Servicing Officer.

            If the Master Servicer or the Servicer at any time seeks to initiate
a foreclosure proceeding in respect of any Mortgaged Property as authorized by
this Agreement or the Servicing Agreement, the Master Servicer or the Servicer
shall deliver or cause to be delivered to the Trustee, for signature, as
appropriate, any court pleadings, requests for trustee's sale or other documents
necessary to effectuate such foreclosure or any legal action brought to obtain
judgment against the Mortgagor on the Mortgage Note or the Mortgage or to obtain
a deficiency judgment or to enforce any other remedies or rights provided by the
Mortgage Note or the Mortgage or otherwise available at law or in equity.

      Section 3.17 Documents, Records and Funds in Possession of the
Master Servicer to be Held for the Trustee Notwithstanding any other provisions
of this Agreement, the Master Servicer shall cause the Servicer to transmit to
the Custodian as required by this Agreement and the Servicing Agreement all
documents and instruments in respect of a Mortgage Loan coming into the
possession of the Servicer from time to time and shall account fully to the
Trustee for any funds received by the Master Servicer or the Servicer or which
otherwise are collected by the Master Servicer or the Servicer as Liquidation
Proceeds, Recoveries or Insurance Proceeds in respect of any Mortgage Loan. All
Mortgage Files and funds collected or held by, or under the control of, the
Master Servicer or the Servicer in respect of any Mortgage Loans, whether from
the collection of principal and interest payments or from Liquidation Proceeds,
including but not limited to, any funds on deposit in the Master Servicer
Custodial Account or the Servicer Custodial Account, shall be held by the Master
Servicer or the Servicer for and on behalf of the Trustee and shall be and
remain the sole and exclusive property of the Trustee, subject to the applicable
provisions of this Agreement and the Servicing Agreement. The Master Servicer
also agrees that it shall not, and shall enforce any requirement under the
Servicing Agreement that the Servicer shall not, knowingly create, incur or
subject any Mortgage File or any funds that are deposited in any Master Servicer
Custodial Account, the Servicer Custodial Account, the Certificate Account or
any Escrow Account, or any funds that otherwise are or may become due or payable
to the Trustee for the benefit of the Certificateholders, to any claim, lien,
security interest, judgment, levy, writ of attachment or other encumbrance
created by the Master Servicer or the Servicer, or assert by legal action or
otherwise any claim or right of setoff against any Mortgage File or any funds
collected on, or in connection with, a Mortgage Loan, except, however, that the
Master Servicer shall be entitled to set off against and deduct from any such
funds any amounts that are properly due and payable to the Master Servicer under
this Agreement.

      Section 3.18 Master Servicer Compensation. As compensation for its
services hereunder, the Master Servicer shall be entitled to a fee in an amount
agreed upon between the Master Servicer and the Securities Administrator,
payable by the Securities Administrator out of its own funds and not out of any
funds of the Trust Estate. The Master Servicer shall also be entitled to
additional compensation in the form of the Master Servicer Custodial Account
Reinvestment Income. The Master Servicer shall be required to pay all expenses
incurred by it in connection with its master servicing activities hereunder and
shall not be entitled to reimbursement therefor except as specifically provided
in this Agreement.

      Section 3.19 Annual Statement as to Compliance. The Master Servicer shall
deliver to the Securities Administrator (and the Securities Administrator will
forward to the Trustee and each Rating Agency), no later than March 15 following
the end of each calendar year commencing with March 2006, an Officer's
Certificate, signed by two officers of the Master Servicer, stating, as to the
signers thereof, that (a) a review of the activities of the Master Servicer
during the preceding calendar year and of the performance of the Master Servicer
under this Agreement or similar agreements has been made under such officer's
supervision, and (b) to the best of such officer's knowledge, based on such
review, the Master Servicer has fulfilled all its obligations under this
Agreement throughout such year, or, if there has been a default in the
fulfillment of any such obligation, specifying each such default known to such
officer and the nature and status thereof.

            In addition, the Master Servicer shall enforce the Servicer's
obligation under the Servicing Agreement to provide a similar statement to the
Securities Administrator relating to compliance with the Servicing Agreement.

      Section 3.20 Annual Independent Public Accountants' Servicing
Statement; Financial Statements The Master Servicer shall enforce the Servicer's
obligation under the Servicing Agreement to provide a report to the Securities
Administrator, as required to be provided each year pursuant to the Servicing
Agreement, prepared by a firm of independent public accountants (who may also
render other services to the Servicer or any affiliate thereof) which is a
member of the American Institute of Certified Public Accountants (i) to the
effect that such firm has, with respect to the Servicer's overall servicing
operations, examined such operations in accordance with the requirements of the
Uniform Single Attestation Program for Mortgage Bankers, stating such firm's
conclusions relating thereto or (ii) commencing with calendar year 2007, in
accordance with Rule 1-02(a)(3) and Rule 2-02(g) of Regulation S-X under the
1933 Act and the Exchange Act, that attests to, and reports on an assessment
made by the Servicer of its compliance with the applicable servicing criteria
set forth in Item 1122(d) of Regulation AB, as required by Rules 13a-18 and
15d-18 under the Exchange Act, and Item 1122(b) of Regulation AB.

      Section 3.21 Advances. The Master Servicer shall enforce the obligations
of the Servicer to make a Periodic Advance in accordance with the Servicing
Agreement. The Servicer shall be entitled to be reimbursed from the Servicer
Custodial Account for all Advances of its own funds made pursuant to the
Servicing Agreement. Based upon information set forth in the servicer reports,
the Master Servicer shall inform the Securities Administrator of the amount of
the Periodic Advance to be made by the Servicer on each applicable Advance Date
no later than the related Remittance Date. If the Servicer fails to make any
required Periodic Advance pursuant to the Servicing Agreement, the Master
Servicer shall (i) unless the Master Servicer determines that such Periodic
Advance would not be recoverable in its good faith business judgment, make such
Periodic Advance not later than the Business Day preceding the related
Distribution Date and (ii) to the extent such failure leads to the termination
of the Servicer and until such time as a successor Servicer is appointed,
continue to make Periodic Advances required pursuant to the Servicing Agreement
for any Distribution Date, within the same time frame set forth in (i) above,
unless the Master Servicer determines (to the extent provided in the Servicing
Agreement) that such Periodic Advance would not be recoverable.

      Section 3.22 Reports to the Securities and Exchange Commission. (a)
The Securities Administrator and the Master Servicer shall reasonably cooperate
with the Depositor in connection with the Trust's satisfying its reporting
requirements under the Exchange Act. Without limiting the generality of the
foregoing, the Securities Administrator shall prepare on behalf of the Trust any
monthly Current Reports on Form 8-K (each, a "Monthly Form 8-K") and Annual
Reports on Form 10-K (each, a "Form 10-K") customary for similar securities as
required by the Exchange Act and the rules and regulations of the Securities and
Exchange Commission thereunder, and the Securities Administrator shall sign and
file (via the Securities and Exchange Commission's Electronic Data Gathering and
Retrieval System) such Forms (other than any Annual Report on Form 10-K, which
shall be signed by the Master Servicer) on behalf of the Trust. Notwithstanding
the previous sentence, the Depositor shall file the Monthly Form 8-K in
connection with the filing of this Agreement.

             (b) Each Monthly Form 8-K shall be filed by the Securities
Administrator within 15 days after each Distribution Date, including a copy of
the monthly statement to Certificateholders delivered pursuant to Section
5.04(b) (each, a "Distribution Date Statement") for such Distribution Date as an
exhibit thereto. On or prior to March 30th of each year (or such earlier date as
may be required by the Exchange Act and the rules and regulations of the
Securities and Exchange Commission), commencing in the calendar year following
the date of this Agreement, the Securities Administrator shall file a Form 10-K,
in substance as required by applicable law or applicable Securities and Exchange
Commission staff's interpretations. Such Form 10-K shall include as exhibits the
Master Servicer's and the Servicer's annual statement of compliance described
under Section 3.19 and the accountant's reports referenced under Section 3.20,
in each case, to the extent they have been timely delivered to the Securities
Administrator. If they are not so timely delivered, the Securities Administrator
shall file an amended Form 10-K including such documents as exhibits reasonably
promptly after they are delivered to the Securities Administrator. The
Securities Administrator shall have no liability with respect to any failure to
properly prepare or file such periodic reports resulting from or relating to the
Securities Administrator's inability or failure to obtain any information not
resulting from its own negligence, willful misconduct or bad faith. The Form
10-K shall also include a certification in the form attached hereto as Exhibit M
(the "Certification"), which shall be signed by a senior officer of the Master
Servicer in charge of the master servicing functions. The Master Servicer shall
deliver the Certification to the Securities Administrator three (3) Business
Days prior to the latest date on which the Form 10-K may be timely filed. The
Securities Administrator, the Depositor and the Master Servicer shall reasonably
cooperate to enable the Securities and Exchange Commission requirements with
respect to the Trust to be met in the event that the Securities and Exchange
Commission issues additional interpretive guidelines or promulgates rules or
regulations, or in the event of any other change of law that would require
reporting arrangements or the allocation of responsibilities with respect
thereto, as described in this Section 3.22, to be conducted or allocated in a
different manner.

            (c) Prior to the latest date on which the Form 10-K may be timely
filed each year, the Securities Administrator shall sign and deliver to the
Master Servicer a certification (in the form attached hereto as Exhibit N) for
the benefit of the Master Servicer and its officers, directors and affiliates
(provided, however, that the Securities Administrator shall not undertake an
analysis of any accountants' report attached as an exhibit to the Form 10-K). In
addition, the Securities Administrator shall indemnify and hold harmless the
Master Servicer, each person, if any, who "controls" the Master Servicer within
the meaning of the 1933 Act, as amended, and their respective officers,
directors, agents and affiliates (collectively, the "Master Servicer Indemnified
Parties") from and against any losses, damages, penalties, fines, forfeitures,
reasonable and necessary legal fees and related costs, judgments and other costs
and expenses arising out of or based upon any inaccuracy in the certification
provided by the Securities Administrator pursuant to this Section 3.22(c), any
breach by the Securities Administrator or any of its officers, directors, agents
or affiliates of its obligations under this Section 3.22(c) or any material
misstatements or omission contained in the certification delivered pursuant to
this Section 3.22(c) or the Securities Administrator's negligence, bad faith or
willful misconduct in connection therewith. If the indemnification provided for
herein is unavailable or insufficient to hold harmless the Master Servicer
Indemnified Parties, then the Securities Administrator agrees that it shall
contribute to the amount paid or payable by such Master Servicer Indemnified
Parties as a result of the losses, claims, damages or liabilities of such Master
Servicer Indemnified Parties in such proportion as is appropriate to reflect the
relative fault of such Master Servicer Indemnified Parties on the one hand and
the Securities Administrator on the other in connection with a breach of the

            No Class of Certificates or Component will be entitled to any
      distributions with respect to the amount payable pursuant to clause (ii)
      of the definition of "Interest Distribution Amount" or "Component Interest
      Distribution Amount" after its Class Certificate Balance or Notional
      Amount, as the case may be, has been reduced to zero.

            For any Group and on any Distribution Date, amounts distributed in
      respect of the Class PO Deferred Amounts (including the distribution of
      the Class PO Recoveries) will not reduce the Component Balance of the
      applicable Class PO Component.

            All distributions in respect of the Interest Distribution Amount for
      a Class or the Component Interest Distribution Amount for a Component will
      be applied first with respect to the amount payable pursuant to clause (i)
      of the definition of "Interest Distribution Amount" or "Component Interest
      Distribution Amount" as applicable, and second with respect to the amount
      payable pursuant to clause (ii) of such definitions.

            On each Distribution Date, the Securities Administrator shall
      distribute any Reimbursement Amount sequentially to each Class of
      Certificates then outstanding which bore the loss to which such
       Reimbursement Amount relates, beginning with the most senior of such
      Classes of Certificates, up to, with respect to each Class, the amount of
      loss borne by such Class. Any Reimbursement Amount remaining after the
      application described in the preceding sentence shall be included in the
      Pool Distribution Amount for the applicable Loan Group.

            (vi) Distributions on the Uncertificated Lower-Tier Interests. On
      each Distribution Date, interest shall be distributed in respect of the
      Uncertificated Lower-Tier Interests (other than the Class 1-LPO Interest,
      Class 2-LPO Interest, Class 3-LPO Interest and Class 4-LPO Interest, at
      the pass-through rate thereon, as described in the next to last paragraph
       of this Section 5.02(a)(vi). All distributions of principal shall be made
      first to the Class 1-LPO Interest, Class 2-LPO Interest, Class 3-LPO
      Interest and Class 4-LPO Interest, so as to keep the principal balances
      thereof at all times equal to the Component Balances of the Class 1-PO
      Component, the Class 2-PO Component, the Class 3-PO Component and the
      Class 4-PO Component, respectively; second, to the Class 1-LS Interest,
      Class 2-LS Interest, Class 3-LS Interest and Class 4-LS Interest, so as to
      keep the principal balances thereof (computed to eight decimal places)
      equal to 0.100% of the Group Subordinate Amount for Loan Group 1, Loan
      Group 2, Loan Group 3 and Loan Group 4, respectively (except that if any
      such amount is greater than on the preceding Distribution Date, the least
      amount of principal shall be distributed to the Class 1-LS Interest, Class
      2-LS Interest, Class 3-LS Interest and Class 4-LS Interest, such that the
      Subordinate Balance Ratio is maintained), and third, any remaining
      principal to the Class 1-L Interest, Class 2-L Interest, Class 3-L
      Interest and Class 4-L Interest. Any distributions of principal made to
      the Uncertificated Lower-Tier Interests pursuant to this paragraph shall
      be made from the Group 1 Mortgage Loans to the Uncertificated Lower-Tier
      Interests beginning with the numeral "1," from the Group 2 Mortgage Loans
      to the Uncertificated Lower-Tier Interests beginning with the numeral "2,"
      from the Group 3 Mortgage Loans to the Uncertificated Lower-Tier Interests
      beginning with the numeral "3" and from the Group 4 Mortgage Loans to the
      Uncertificated Lower-Tier Interests beginning with the numeral "4."

            Realized Losses shall be applied after all distributions have been
      made on each Distribution Date first, to the Class 1-LPO Interest, Class
      2-LPO Interest, Class 3-LPO Interest and Class 4-LPO Interest, so as to
      keep their principal balances equal to the Component Balances of the Class
      1-PO Component, the Class 2-PO Component, the Class 3-PO Component and the
      Class 4-PO Component, respectively; second, to the Class 1-LS Interest,
      Class 2-LS Interest, Class 3-LS Interest and Class 4-LS Interest, so as to
      keep the principal balances thereof (computed to eight decimal places)
      equal to 0.100% of the Group Subordinate Amount for Loan Group 1, Loan
      Group 2, Loan Group 3 and Loan Group 4, respectively (except that if any
      such amount is greater than on the preceding Distribution Date, the least
      amount of Realized Losses shall be allocated to the Class 1-LS Interest,
      Class 2-LS Interest, Class 3-LS Interest and Class 4-LS Interest such that
      the Subordinate Balance Ratio is maintained); and third, the remaining
      Realized Losses shall be allocated to the Class 1-L Interest, Class 2-L
      Interest, Class 3-L Interest and Class 4-L Interest. Any Realized Losses
      allocated to the Uncertificated Lower-Tier Interests pursuant to this
      paragraph shall be (a) from Realized Losses allocated to Loan Group 1 in
      the case of Uncertificated Lower-Tier Interests beginning with the numeral
      "1," (b) from Realized Losses allocated to Loan Group 2 in the case of
      Uncertificated Lower-Tier Interests beginning with the numeral "2," (c)
      from Realized Losses allocated to Loan Group 3 in the case of
      Uncertificated Lower-Tier Interests beginning with the numeral "3" and (d)
      from Realized Losses allocated to Loan Group 4 in the case of
      Uncertificated Lower-Tier Interests beginning with the numeral "4."

            As of any date, the aggregate principal balance of the Class 1-L
      Interest and the Class 1-LS Interest shall equal the aggregate Pool Stated
      Principal Balance (Non-PO Portion) of Loan Group 1. As of any date, the
      aggregate principal balance of the Class 2-L Interest and the Class 2-LS
      Interest shall equal the aggregate Pool Stated Principal Balance (Non-PO
      Portion) of Loan Group 2. As of any date, the aggregate principal balance
      of the Class 3-L Interest and the Class 3-LS Interest shall equal the
      aggregate Pool Stated Principal Balance (Non-PO Portion) of Loan Group 3.
      As of any date, the aggregate principal balance of the Class 4-L Interest
      and the Class 4-LS Interest shall equal the aggregate Pool Stated
      Principal Balance (Non-PO Portion) of Loan Group 4. As of any date, (i)
      the principal balance of the Class 1-LPO Interest will be equal to the
      Component Balance of the Class 1-PO Component, (ii) the principal balance
      of the Class 2-LPO Interest will be equal to the Component Balance of the
      Class 2-PO Component, (iii) the principal balance of the Class 3-LPO
      Interest will be equal to the Component Balance of the Class 3-PO
      Component and (iv) the principal balance of the Class 4-LPO Interest will
      be equal to the Component Balance of the Class 4-PO Component. As of any
      date, (i) the notional amount of the Class 1-LIO Interest will be equal to
      the Class 1-IO Notional Amount, (ii) the notional amount of the Class
      2-LIO Interest will be equal to the Class 2-IO Notional Amount, (iii) the
      notional amount of the Class 3-LIO Interest will be equal to the Class
      3-IO Notional Amount and (iv) the notional amount of the Class 4-LIO
      Interest will be equal to the Class 4-IO Notional Amount.

            The pass-through rate with respect to the Class 1-L Interest and the
      Class 1-LS Interest shall be 5.750% per annum. The pass-through rate with
      respect to the Class 2-L Interest and the Class 2-LS Interest shall be
      5.857% per annum. The pass-through rate with respect to the Class 3-L
      Interest and the Class 3-LS Interest shall be 6.500% per annum. The
      pass-through rate with respect to the Class 4-L Interest and the Class
      4-LS Interest shall be 6.500% per annum. The pass-through rate with
      respect to the Class 1-LIO Interest shall be the same as the Pass-Through
      Rate for the Class 1-IO Certificates, as such rate is described in the
      Preliminary Statement. The pass-through rate with respect to the Class
      2-LIO Interest, Class 3-LIO Interest and Class 4-LIO Interest shall be the
      same as the Pass-Through Rate for the Class 2-IO Component, Class 3-IO
      Component and Class 4-IO Component, respectively, as each such rate is
      described in the Preliminary Statement. The Class 1-LPO Interest, Class
      2-LPO Interest, Class 3-LPO Interest and Class 4-LPO Interest are
      principal-only interests and are not entitled to distributions of
      interest.

            Any Non-Supported Interest Shortfalls and Relief Act Reductions will
      be allocated to each Uncertificated Lower-Tier Interest in the same
      relative proportions as interest is allocated to such Uncertificated
      Lower-Tier Interest. Amounts distributed to the Uncertificated Lower-Tier
      Interests in respect of principal and interest with respect to any
      Distribution Date are referred to herein collectively as the "Lower-Tier
      Distribution Amount."

            (vii) Distributions on the Uncertificated Middle-Tier Interests. On
      each Distribution Date, each Uncertificated Middle-Tier Interest (other
      than the Class 1-MIO Interest, Class 2-MIO Interest, Class 3-MIO Interest
      and Class 4-MIO Interest) shall receive distributions in respect of
      principal in an amount equal to the amount of principal distributed to its
      respective Corresponding Upper-Tier Class, Classes or Component, as
      provided herein. On each Distribution Date, each Uncertificated
      Middle-Tier Interest (other than the Class 1-MPO Interest, Class 2-MPO
      Interest, Class 3-MPO Interest and Class 4-MPO Interest) shall receive
      distributions in respect of interest in an amount equal to the Interest
      Accrual Amounts and Unpaid Interest Shortfalls, as the case may be, in
      respect of its Corresponding Upper-Tier Class, Classes or Component, in
      each case to the extent actually distributed thereon. Such amounts
      distributed to the Uncertificated Middle-Tier Interests in respect of
      principal and interest with respect to any Distribution Date are referred
      to herein collectively as the "Middle-Tier Distribution Amount."

            As of any date, the principal balance or notional amount of each
      Uncertificated Middle-Tier Interest equals the aggregate of the Class
      Certificate Balances, Component Balance or Notional Amounts of the
      respective Corresponding Upper-Tier Class, Classes or Component or, in the
      case of the Class 1-A-M1 Interest or Class 2-A-M1 Interest, the Class
      Certificate Balance of the Class 1-A-1 Certificates and Class 2-A-2
      Certificates, respectively. The initial principal balance or notional
      amount of each Uncertificated Middle-Tier Interest equals the aggregate of
      the Initial Class Certificate Balances, Component Balance or Initial
      Notional Amounts of the respective Corresponding Upper-Tier Class, Classes
      or Component or, in the case of the Class 1-A-M1 Interest or Class 2-A-M1
      Interest, the Initial Class Certificate Balance of the Class 1-A-1
      Certificates and Class 2-A-1 Certificates, respectively.

            The pass-through rate with respect to the Class 1-A-M1 Interest,
      Class 1-A-M3 Interest and Class 1-A-MUR Interest shall be 5.750% per
      annum. The pass-through rate with respect to the Class 2-A-M1 Interest and
      Class 2-A-M3 Interest shall be 5.750% per annum. The pass-through rate
      with respect to the Class 2-A-M8 Interest shall be 6.000% per annum. The
      pass-through rate with respect to the Class 3-A-M1 Interest shall be
      6.500% per annum. The pass-through rate with respect to the Class 4-A-M1
      Interest shall be 6.500% per annum. The pass-through rate with respect to
      the Class B-M1 Interest, Class B-M2 Interest, Class B-M3 Interest, Class
      B-M4 Interest, Class B-M5 Interest and Class B-M6 Interest shall be the
      weighted average of the Class 1-LS Interest, Class 2-LS Interest, Class
      3-LS Interest and Class 4-LS Interest. The pass-through rate with respect
      to the Class 1-MIO Interest shall be a per annum rate equal to the
      Pass-Through Rate of the Class 1-IO Certificates. The pass-through rate
      with respect to the Class 2-MIO Interest shall be a per annum rate equal
      to the Pass-Through Rate of the Class 2-IO Component. The pass-through
      rate with respect to the Class 3-MIO Interest shall be a per annum rate
      equal to the Pass-Through Rate of the Class 3-IO Component. The
      pass-through rate with respect to the Class 4-MIO Interest shall be a per
      annum rate equal to the Pass-Through Rate of the Class 4-IO Component. The
      Class 1-MPO Interest, Class 2-MPO Interest, Class 3-MPO Interest and Class
      4-MPO Interest are principal-only interests and are not entitled to
      distributions of interest.

            (b) (i) On each Distribution Date prior to the Senior Credit Support
Depletion Date, the amount distributable to the Group 1 Senior Certificates

allocated to the Class 1-A-8 Certificates pursuant to this paragraph will be
distributed to the Class 1-A-1 Certificates until the Class Certificate Balance
of the Class 1-A-1 Certificates has been reduced to zero.

            The Class 1-A-2, Class 1-IO, Class 2-A-2 and Class CB-IO
Certificates are Interest Only Certificates and are not entitled to
distributions in respect of principal.

            (v) Notwithstanding the foregoing, on each Distribution Date prior
to the Senior Credit Support Depletion Date but on or after the date on which
the aggregate Class Certificate Balance of the Senior Certificates of a Group
has been reduced to zero, amounts otherwise distributable as principal payments
on the Subordinate Certificates together with the applicable Senior Principal
Distribution Amount will be paid as principal to the Classes of Senior
Certificates of the other Groups in accordance with the priorities set forth for
the applicable Group in (b) (i), (ii), (iii) or (iv) above, provided that on
such Distribution Date (a) the Aggregate Subordinate Percentage for such
Distribution Date is less than twice the initial Aggregate Subordinate
Percentage or (b) the outstanding principal balance of all Mortgage Loans
(including, for this purpose, any Mortgage Loans in foreclosure, any REO
Property and any Mortgage Loan for which the Mortgagor has filed for bankruptcy
after the Closing Date) delinquent 60 days or more (averaged over the preceding
six month period), as a percentage of the aggregate Class Certificate Balance of
the Subordinate Certificates, is equal to or greater than 50%. If the Senior
Certificates of two or more Groups remain outstanding, the distributions
described above will be made to the Senior Certificates of such Groups, pro
rata, in proportion to the aggregate class balance of the Senior Certificates of
each such Group. In addition, after giving effect to the previous sentence, if
on any Distribution Date the aggregate Class Certificate Balance of the Senior
Certificates of a Group is greater than the Adjusted Pool Amount (Non-PO
Portion) of related Loan Group (any such Group, the "Undercollateralized Group"
and any such excess, the "Undercollateralized Amount"), all amounts otherwise
distributable as principal on the Subordinate Certificates pursuant to
5.02(a)(iv)(L), (J), (H), (F), (D) and (B), in that order, will be paid as
principal to the Senior Certificates of the Undercollateralized Group together
with the applicable Senior Principal Distribution Amount in accordance with the
priorities set forth for the applicable Group above under (b)(i), (ii), (iii) or
(iv) until the aggregate Class Certificate Balance of the Senior Certificates of
the Undercollateralized Group equals the Adjusted Pool Amount (Non-PO Portion)
of the Related Loan Group. If two or more Groups are Undercollateralized Groups,
the distributions described above will be made, pro rata, in proportion to the
amount by which the aggregate class balance of the Senior Certificates of each
such Group exceeds the Pool Principal Balance (Non-PO Portion) of the related
Loan Group. Also, the amount of any Class Unpaid Interest Shortfalls and
Component Unpaid Interest Shortfalls with respect to the Undercollateralized
Group (including any Class Unpaid Interest Shortfalls or Component Unpaid
Interest Shortfalls for such Distribution Date) will be paid to the
Undercollateralized Group pursuant to Section 5.02(a)(i) prior to the payment of
any Undercollateralized Amount from amounts otherwise distributable as principal
on the Subordinate Certificates pursuant to Section 5.02(a)(iv)(L), (J), (H),
(F), (D) and (B), in that order. Such amount will be paid to the Senior
Certificates and Components (other than the Class PO Component) of such
Undercollateralized Group in accordance with the priorities set forth in Section
5.02(a)(i) up to their Interest Distribution Amounts or Component Interest
Distribution Amounts for such Distribution Date.

            The Class PO Deferred Amounts for the Class PO Components will be
paid from amounts otherwise distributable as principal on the Subordinate
Certificates before any payments are made pursuant to the preceding paragraph.

            (c) On each Distribution Date, Accrued Certificate Interest for each
Class of Certificates (other than the Class CB-IO Certificates) and Accrued
Component Interest for each Class IO Component for such Distribution Date shall
be reduced by such Class' or Component's pro rata share, based on such Class'
Interest Distribution Amount or Component's Component Interest Distribution
Amount for such Distribution Date, without taking into account the allocation
made by this Section 5.02(c), of an amount equal to the sum of (A) Non-Supported
Interest Shortfalls, (B) on and after the Senior Credit Support Depletion Date,
any other Realized Loss on the Mortgage Loans allocable to interest and (C)
Relief Act Reductions incurred on any Mortgage Loans during the calendar month
preceding the month of such Distribution Date.

            (d) Notwithstanding the priority and allocation contained in Section
5.02(a)(iv), if with respect to any Class of Subordinate Certificates on any
Distribution Date, (i) the aggregate of the Class Certificate Balances
immediately prior to such Distribution Date of all Classes of Subordinate
Certificates that have a higher numerical Class designation than such Class,
divided by (ii) the aggregate Pool Stated Principal Balance (Non-PO Portion) of
the Loan Groups immediately prior to such Distribution Date (for each Class, the
"Fractional Interest") is less than the Original Fractional Interest for such
Class, no distribution of principal will be made to any Classes of Subordinate
Certificates junior to such Class (the "Restricted Classes"), and the Class
Certificate Balances of the Restricted Classes of Subordinate Certificates will
not be used in determining the Pro Rata Share for the Subordinate Certificates
that are not Restricted Classes. If the aggregate Class Certificate Balances of
the Subordinate Certificates that are not Restricted Classes are reduced to
zero, notwithstanding the previous sentence, any funds remaining will be
distributed sequentially to the Subordinate Certificates that are Restricted
Classes in order of their respective numerical Class designations (beginning
with the Class of Subordinate Certificates that is a Restricted Class then
outstanding with the lowest numerical Class designation).

            (e) Any amounts distributed to the Class 1-A-1 and Class 2-A-1
Certificates from the applicable Reserve Fund shall be deemed to be a
distribution to such Certificates from the Grantor Trust as payments on a
notional principal contract in the nature of a cap contract written by Banc of
America Securities LLC.

       Section 5.03 Allocation of Losses. (a) No later than five (5)
Business Days prior to the related Distribution Date, the Master Servicer shall
inform the Securities Administrator in writing with respect to each Mortgage
Loan: (1) whether any Realized Loss is a Deficient Valuation or a Debt Service
Reduction, (2) of the amount of such loss or Deficient Valuation, or of the
terms of such Debt Service Reduction and (3) of the total amount of Realized
Losses on the Mortgage Loans in each Loan Group. Based on such information, the
Securities Administrator shall determine the total amount of Realized Losses on
the Mortgage Loans in each Loan Group with respect to the related Distribution
Date. Realized Losses shall be allocated to the Certificates by a reduction in
the Class Certificate Balances of the designated Classes pursuant to the
operation of Section 5.03(b).

            (b) The Component Balance of the Class PO Component of a Group shall
be reduced on each Distribution Date by the amount, if any, by which the
Component Balance of such Class PO Component (after giving effect to the amounts
to be distributed as a distribution of principal and the allocation of Realized
Losses on such Distribution Date) exceeds the Adjusted Pool Amount (PO Portion)
for such Loan Group for such Distribution Date.

            The Class Certificate Balance of the Class of Subordinate
Certificates then outstanding with the highest numerical Class designation shall
be reduced or increased on each Distribution Date by the amount, if any,
necessary such that the aggregate of the Class Certificate Balances of all
outstanding Classes of Certificates (after giving effect to the amount to be
distributed as a distribution of principal and the allocation of the Class PO
Deferred Amounts on such Distribution Date) equals the sum of the Adjusted Pool
Amounts (Non-PO Portion) for such Distribution Date.

            After the Senior Credit Support Depletion Date, the Class
Certificate Balances of the Senior Certificates of a Group in the aggregate
shall be reduced or increased on each Distribution Date by the amount, if any,
necessary such that the aggregate of the Class Certificate Balances of all
outstanding Classes of Senior Certificates of such Group (after giving effect to
the amount to be distributed as a distribution of principal on such Distribution
Date) equals the Adjusted Pool Amount (Non-PO Portion) for the Related Loan
Group for such Distribution Date.

            Any such reduction or increase shall be allocated among the Senior
Certificates of such Group based on the Class Certificate Balances immediately
prior to such Distribution Date until the Class Certificate Balances thereof
have been reduced to zero.

            (c) Any reduction or increase in the Class Certificate Balance of a
Class of Certificates pursuant to Section 5.03(b) above shall be allocated among
the Certificates of such Class in proportion to their respective Percentage
Interests.

            (d) The calculation of the amount to be distributed as principal to
any Class of Subordinate Certificates with respect to a Distribution Date (the
"Calculated Principal Distribution") shall be made prior to the allocation of
any Realized Losses for such Distribution Date; provided, however, the actual
payment of principal to the Classes of Certificates shall be made subsequent to
the allocation of Realized Losses for such Distribution Date. In the event that
after the allocation of Realized Losses for a Distribution Date, the Calculated
Principal Distribution for a Class of Subordinate Certificates is greater than
the Class Certificate Balance of such Class, the excess shall be distributed
first, sequentially, to the Classes of Subordinate Certificates then outstanding
(beginning with the Class of Subordinate Certificates then outstanding with the
lowest numerical designation) until the respective Class Certificate Balance of
each such Class is reduced to zero and then to the Senior Certificates of the
related Group, pro rata, in accordance with the priorities set forth in Section
5.02.

            (e) After the Senior Credit Support Depletion Date, on any
Distribution Date on which the Class 1-A-4 Loss Allocation Amount is greater
than zero, the Class Certificate Balance of the Class 1-A-4 Certificates will be
reduced by the Class 1-A-4 Loss Allocation Amount and, notwithstanding Section
5.03(b), the Class Certificate Balance of the Class 1-A-3 Certificates will not
be reduced by the Class 1-A-4 Loss Allocation Amount. Notwithstanding the
foregoing, on any Distribution Date in which the Class 1-A-3 Loss Amount exceeds
the Class Certificate Balance of the Class 1-A-4 Certificates prior to any
reduction for the Class 1-A-4 Loss Allocation Amount, such excess will be
distributed in reduction of the Class Certificate Balance of the Class 1-A-3
Certificates. After the Senior Credit Support Depletion Date, on any
Distribution Date on which the Class 1-A-8 Loss Allocation Amount is greater
than zero, the Class Certificate Balance of the Class 1-A-8 Certificates will be
reduced by the Class 1-A-8 Loss Allocation Amount and, notwithstanding Section
5.03(b), the Class Certificate Balance of the Class 1-A-1 Certificates will not
be reduced by the Class 1-A-8 Loss Allocation Amount. Notwithstanding the
foregoing, on any Distribution Date in which the Class 1-A-1 Loss Amount exceeds
the Class Certificate Balance of the Class 1-A-8 Certificates prior to any
reduction for the Class 1-A-8 Loss Allocation Amount, such excess will be
distributed in reduction of the Class Certificate Balance of the Class 1-A-1
Certificates. After the Senior Credit Support Depletion Date, on any
Distribution Date on which the Class 2-A-4 Loss Allocation Amount is greater
than zero, the Class Certificate Balance of the Class 2-A-4 Certificates will be
reduced by the Class 2-A-4 Loss Allocation Amount and, notwithstanding Section
5.03(b), the Class Certificate Balance of the Class 2-A-3 Certificates will not
be reduced by the Class 2-A-4 Loss Allocation Amount. Notwithstanding the
foregoing, on any Distribution Date in which the Class 2-A-3 Loss Amount exceeds
the Class Certificate Balance of the Class 2-A-4 Certificates prior to any
reduction for the Class 2-A-4 Loss Allocation Amount, such excess will be
distributed in reduction of the Class Certificate Balance of the Class 2-A-3
Certificates.

            Any increase allocated to the Class 1-A-3 Certificates pursuant to
Section 5.03(b) will instead increase the Class Certificate Balance of the Class
1-A-4 Certificates, any increase allocated to the Class 1-A-1 Certificates
pursuant to Section 5.03(b) will instead increase the Class Certificate Balance
of the Class 1-A-8 Certificates and any increase allocated to the Class 2-A-3
Certificates pursuant to Section 5.03(b) will instead increase the Class
Certificate Balance of the Class 2-A-4 Certificates.

            (f) Notwithstanding any other provision of this Section 5.03, no
Class Certificate Balance of a Class will be increased on any Distribution Date
such that the Class Certificate Balance of a Class exceeds its Initial Class
Certificate Balance less all distributions of principal previously distributed
in respect of such Class on prior Distribution Dates (excluding in the case of
any Class of Subordinate Certificates any principal otherwise payable to such
Class of Subordinate Certificates but used to pay any Class PO Deferred Amount).

            (g) With respect to any Distribution Date, Realized Losses allocated
pursuant to this Section 5.03 will be allocated to each Uncertificated
Lower-Tier Interest as described in Section 5.02(a) and to each Uncertificated
Middle-Tier Interest in an amount equal to the Realized Losses allocated to such
Uncertificated Middle-Tier Interest's Corresponding Upper-Tier Class, Classes or
Component.

      Section 5.04 Statements to Certificateholders. (a) Prior to the
Distribution Date in each month, based upon the information provided to the
Securities Administrator on the Master Servicer's Certificate delivered to the
Securities Administrator pursuant to Section 4.01, the Securities Administrator

      such distribution;

            (iii) if the distribution to the Holders of such Class of
      Certificates is less than the full amount that would be distributable to
      such Holders if there were sufficient funds available therefor, the amount
      of the shortfall and the allocation thereof as between principal and
      interest;

            (iv) the Class Certificate Balance of each Class of Certificates and

      Date;

            (vii) the amount of the Servicing Fee paid to or retained by the
      Servicer with respect to each Loan Group and such Distribution Date;

      Periodic Advances outstanding as of the close of business on such
      Distribution Date;

            (x) for each Loan Group, the number and aggregate principal amounts
       of Mortgage Loans (A) delinquent (exclusive of Mortgage Loans in

      days and (4) 91 or more days, (B) in foreclosure, as of the close of
      business on the last day of the calendar month preceding such Distribution
      Date and (C) in bankruptcy, as of the close of business on the last day of
      the calendar month preceding such Distribution Date;

            (xi) for each Loan Group, with respect to any Mortgage Loan that
      became an REO Property during the preceding calendar month, the loan
      number and Stated Principal Balance of such Mortgage Loan as of the close
      of business on the Determination Date preceding such Distribution Date and
      the date of acquisition thereof;

            (xii) for each Loan Group, the total number and principal balance of
      any REO Properties (and market value, if available) as of the close of
      business on the Determination Date preceding such Distribution Date;

            (xiii) for each Loan Group, the aggregate amount of Realized Losses

      and

            (xvii) for each Loan Group, the amount of Recoveries, the Class PO
      Recovery and the Non-PO Recovery.

            (b) No later than each Distribution Date, the Securities
Administrator, based upon information supplied to it on the Master Servicer's
Certificate, shall make available to each Holder of a Certificate, each Rating
Agency and the Master Servicer, a statement setting forth the information set
forth in Section 5.04(a).

            In the case of information furnished pursuant to clauses (i) and
(ii) of Section 5.04(a), the amounts shall be expressed as a dollar amount per
Certificate with a $1,000 denomination.

            On each Distribution Date, the Securities Administrator shall
prepare and furnish to each Financial Market Service, in electronic or such
other format and media mutually agreed upon by the Securities Administrator, the
Financial Market Service and the Depositor, the information contained in the
statement described in Section 5.04(a) for such Distribution Date.

            The Securities Administrator will make the monthly statement to
Certificateholders (and, at its option, any additional files containing the same
information in an alternative format) available each month to Certificateholders
and other parties to this Agreement via the Securities Administrator's Internet
website. The Securities Administrator's Internet website shall initially be
located at "www.ctslink.com." Assistance in using the website can be obtained by
calling the Securities Administrator's customer service desk at (301) 815-6600.
Parties that are unable to use the website are entitled to have a paper copy
mailed to them via first class mail by calling the customer service desk and
indicating such. The Securities Administrator shall have the right to change the
way the monthly statements to Certificateholders are distributed in order to
make such distribution more convenient and/or more accessible to the above
parties and the Securities Administrator shall provide timely and adequate
notification to all above parties regarding any such changes.

            Within a reasonable period of time after the end of each calendar
year, the Securities Administrator shall furnish to each Person who at any time
during the calendar year was the Holder of a Certificate, if requested in
writing by such Person, a statement containing the information set forth in
clauses (i) and (ii) of Section 5.04(a), in each case aggregated for such
calendar year or applicable portion thereof during which such Person was a
Certificateholder. Such obligation of the Securities Administrator shall be
deemed to have been satisfied to the extent that substantially comparable
information shall be provided by the Securities Administrator pursuant to any
requirements of the Code as from time to time in force.

            The Securities Administrator shall deliver to the Holders of
Certificates any reports or information the Securities Administrator is required
by this Agreement or the Code, Treasury Regulations or REMIC Provisions to
deliver to the Holders of Certificates, and the Securities Administrator shall
prepare and provide to the Certificateholders (by mail, telephone, or
publication as may be permitted by applicable Treasury Regulations) such other
reasonable information as the Securities Administrator deems necessary or
appropriate or is required by the Code, Treasury Regulations, and the REMIC
Provisions including, but not limited to, (i) information to be reported to the
Holder of the Residual Certificate for quarterly notices on Schedule Q (Form
1066) (which information shall be forwarded to the Holder of the Residual
Certificate by the Securities Administrator), (ii) information to be provided to
the Holders of Certificates with respect to amounts which should be included as
interest and original issue discount in such Holders' gross income and (iii)
information to be provided to all Holders of Certificates setting forth the
percentage of each REMIC's assets, determined in accordance with Treasury
Regulations using a convention, not inconsistent with Treasury Regulations,
selected by the Securities Administrator in its absolute discretion, that
constitute real estate assets under Section 856 of the Code, and assets
described in Section 7701(a)(19)(C) of the Code; provided, however, that in
setting forth the percentage of such assets of each REMIC created hereunder,
nothing contained in this Agreement, including without limitation Section 7.03
hereof, shall be interpreted to require the Securities Administrator
periodically to appraise the fair market values of the assets of the Trust
Estate or to indemnify the Trust Estate or any Certificateholders from any
adverse federal, state or local tax consequences associated with a change
subsequently required to be made in the Depositor's initial good faith
determinations of such fair market values (if subsequent determinations are
required pursuant to the REMIC Provisions) made from time to time.

      Section 5.05 Tax Returns and Reports to Certificateholders. (a) For
federal income tax purposes, each REMIC created hereunder shall have a taxable
year ending on December 31st and shall maintain its books on the accrual method
of accounting.

            (b) The Securities Administrator shall prepare or cause to be
prepared, shall cause to be timely signed by the Trustee, and shall file or
cause to be filed with the Internal Revenue Service and applicable state or
local tax authorities income tax information returns for each taxable year with
respect to each REMIC created hereunder containing such information at the times
and in the manner as may be required by the Code, the Treasury Regulations or
state or local tax laws, regulations, or rules, and shall furnish or cause to be
furnished to each REMIC created hereunder and the Certificateholders the
schedules, statements or information at such times and in such manner as may be
required thereby. The Master Servicer shall provide on a timely basis to the
Securities Administrator or its designee such information with respect to the
assets of the Trust Estate as is in its possession and reasonably required by
the Securities Administrator to enable it to perform its obligations under this
Article V. Within 30 days of the Closing Date, the Securities Administrator
shall obtain for each REMIC created hereunder a taxpayer identification number
on Form SS-4 or as otherwise permitted by the Internal Revenue Service, and
shall furnish or cause to be furnished to the Internal Revenue Service, on Form
8811 or as otherwise required by the Code or the Treasury Regulations, the name,
title, address and telephone number of the person that Holders of the
Certificates may contact for tax information relating thereto, together with
such additional information at the time or times and in the manner required by
the Code or the Treasury Regulations. Such federal, state, or local income tax
or information returns shall be signed by the Trustee, or such other Person as
may be required to sign such returns by the Code, the Treasury Regulations or
state or local tax laws, regulations, or rules.

            (c) In the first federal income tax return of each REMIC created
hereunder for its short taxable year ending December 31, 2005, REMIC status
shall be elected for such taxable year and all succeeding taxable years.

            (d) The Securities Administrator will maintain or cause to be
maintained such records relating to each REMIC created hereunder, including but
not limited to records relating to the income, expenses, assets and liabilities
of the Trust Estate, and the initial fair market value and adjusted basis of the
Trust Estate property and assets determined at such intervals as may be required
by the Code or the Treasury Regulations, as may be necessary to prepare the
foregoing returns, schedules, statements or information.

      Section 5.06 Tax Matters Person. The Tax Matters Person shall have the
same duties with respect to the applicable REMIC as those of a "tax matters
partner" under Subchapter C of Chapter 63 of Subtitle F of the Code. The Holder
of the Class 1-A-R Certificate is hereby designated as the Tax Matters Person
for the Upper-Tier REMIC, Middle-Tier REMIC and the Lower-Tier REMIC. By its
acceptance of the Class 1-A-R Certificate, such Holder irrevocably appoints the
Securities Administrator as its agent to perform all of the duties of the Tax
Matters Person for the Upper-Tier REMIC, Middle-Tier REMIC and the Lower-Tier
REMIC.

      Section 5.07 Rights of the Tax Matters Person in Respect of the
Securities Administrator. The Securities Administrator shall afford the Tax
Matters Person, upon reasonable notice during normal business hours, access to
all records maintained by the Securities Administrator in respect of its duties
hereunder and access to officers of the Securities Administrator responsible for
performing such duties. Upon request, the Securities Administrator shall furnish
the Tax Matters Person with its most recent report of condition published
pursuant to law or to the requirements of its supervisory or examining authority
publicly available. The Securities Administrator shall make available to the Tax
Matters Person such books, documents or records relating to the Securities
Administrator's services hereunder as the Tax Matters Person shall reasonably
request. The Tax Matters Person shall not have any responsibility or liability
for any action or failure to act by the Securities Administrator and is not
obligated to supervise the performance of the Securities Administrator under
this Agreement or otherwise.

      Section 5.08 REMIC Related Covenants. For as long as any REMIC
created hereunder shall exist, the Trustee, the Securities Administrator, the
Depositor and the Master Servicer shall act in accordance herewith to assure
continuing treatment of each REMIC created hereunder as a REMIC and avoid the
imposition of tax on any REMIC created hereunder. In particular:

            (a) Neither the Securities Administrator nor the Trustee shall
create, or permit the creation of, any "interests" in any REMIC created
hereunder within the meaning of Code Section 860D(a)(2) other than the interests
represented by the Regular Certificates, the Residual Certificate, the
Uncertificated Middle-Tier Interests and the Uncertificated Lower-Tier
Interests.

            (b) Except as otherwise provided in the Code, (i) the Depositor and
the Master Servicer shall not contribute to the Trust Estate and the Trustee
shall not accept property unless substantially all of the property held in each
REMIC constitutes either "qualified mortgages" or "permitted investments" as
defined in Code Sections 860G(a)(3) and (5), respectively, and (ii) no property
shall be contributed, or deemed contributed, to any REMIC created hereunder
after the start-up day unless such contribution would not subject the Trust
Estate to the 100% tax on contributions to a REMIC created hereunder after the
start-up day of such REMIC imposed by Code Section 860G(d).

            (c) The Securities Administrator, on behalf of the Trustee, shall
not accept on behalf of any REMIC created hereunder any fee or other
compensation for services and none of the Securities Administrator, the Trustee
or the Master Servicer shall knowingly accept, on behalf of the Trust Estate any
income from assets other than those permitted to be held by a REMIC.

            (d) Neither the Securities Administrator, on behalf of the Trustee,
nor the Trustee shall sell or permit the sale of all or any portion of the
Mortgage Loans (other than in accordance with Sections 2.02 or 2.04), unless
such sale is pursuant to a "qualified liquidation" of the applicable REMIC as
defined in Code Section 860F(a)(4)(A) and in accordance with Article X.

            (e) The Securities Administrator shall maintain books with respect
to the Trust and each REMIC created hereunder on a calendar year taxable year
basis and on an accrual basis.

            None of the Master Servicer, the Securities Administrator or the
Trustee shall engage in a "prohibited transaction" (as defined in Code Section
860F(a)(2)), except that, with the prior written consent of the Master Servicer
and the Depositor, the Securities Administrator may engage in the activities
otherwise prohibited by the foregoing paragraphs (b), (c) and (d); provided that
the Master Servicer shall have delivered to the Securities Administrator an
Opinion of Counsel to the effect that such transaction will not result in the
imposition of a tax on any REMIC created hereunder and will not disqualify any
such REMIC from treatment as a REMIC; and, provided further, that the Master
Servicer shall have demonstrated to the satisfaction of the Securities
Administrator that such action will not adversely affect the rights of the
Holders of the Certificates and the Securities Administrator and that such
action will not adversely impact the rating of the Certificates.

      Section 5.09 Determination of LIBOR.On each Rate Determination Date for a
Class of LIBOR Certificates, the Securities Administrator shall determine LIBOR
for the applicable Distribution Date on the basis of the British Bankers'
Association ("BBA") "Interest Settlement Rate" for one-month deposits in U.S.
Dollars as found on Telerate page 3750 as of 11:00 A.M. London time on such Rate
Determination Date. As used herein, "Telerate page 3750" means the display
designated as page 3750 on the Reuters Telerate Service.

             If on any Rate Determination Date for a Class of LIBOR Certificates,
the Securities Administrator is unable to determine LIBOR on the basis of the
method set forth in the preceding paragraph, LIBOR for the applicable
Distribution Date will be whichever is higher of (x) LIBOR as determined on the
previous Rate Determination Date for such Class of LIBOR Certificates or (y) the
Reserve Interest Rate. The "Reserve Interest Rate" will be the rate per annum
which the Securities Administrator determines to be either (A) the arithmetic
mean (rounding such arithmetic mean upwards if necessary to the nearest whole
multiple of 1/16%) of the one-month U.S. Dollar lending rates that New York City
banks selected by the Securities Administrator are quoting, on the relevant Rate
Determination Date, to the principal London offices of at least two leading
banks in the London interbank market or (B) in the event that the Securities
Administrator can determine no such arithmetic mean, the lowest one-month U.S.
Dollar lending rate that the New York City banks selected by the Securities
Administrator are quoting on such Rate Determination Date to leading European
banks.

            If on any Rate Determination Date for a Class of LIBOR Certificates,
the Securities Administrator is required but is unable to determine the Reserve
Interest Rate in the manner provided in the preceding paragraph, LIBOR for the
applicable Distribution Date will be LIBOR as determined on the previous Rate
Determination Date for such Class of LIBOR Certificates, or, in the case of the
first Rate Determination Date for which the Securities Administrator is required
to determine LIBOR, 4.36%.

            The establishment of LIBOR by the Securities Administrator and the
Securities Administrator's subsequent calculation of the rates of interest
applicable to each of the LIBOR Certificates in the absence of manifest error,
will be final and binding. After a Rate Determination Date, the Securities
Administrator shall provide the Pass-Through Rates of the LIBOR Certificates for
the related Distribution Date to Beneficial Owners or Holders of LIBOR
Certificates who place a telephone call to the Securities Administrator at (301)
815-6600 and make a request therefor.

      Section 5.10 Master Servicer, Securities Administrator and Trustee

                                   ARTICLE VI

                                THE CERTIFICATES

      Section 6.01 The Certificates. The Classes of Senior Certificates and the
Subordinate Certificates shall be substantially in the forms attached hereto as
Exhibits 1-A-1, 1-A-2, 1-A-3, 1-A-4, 1-A-5, 1-A-6, 1-A-7, 1-A-8, 1-IO, 1-A-R,
2-A-1, 2-A-2, 2-A-3, 2-A-4, 2-A-5, 2-A-6, 2-A-7, 2-A-8, 3-A-1, 4-A-1, CB-IO,
X-PO, B-1, B-2, B-3, B-4, B-5, B-6 and C (reverse of all Certificates) and
shall, on original issue, be executed by the Securities Administrator and shall
be authenticated and delivered by the Securities Administrator to or upon the
order of the Depositor upon receipt by the Custodian of the documents specified
in Section 2.01. The Classes of Certificates shall be available to investors in
minimum denominations of initial Certificate Balance (or initial notional
amount) and integral multiples in excess thereof set forth in the Preliminary
Statement. The Senior Certificates (other than the Class 1-A-R Certificate) and
the Class B-1, Class B-2 and Class B-3 Certificates shall initially be issued in
book-entry form through the Depository and delivered to the Depository or,
pursuant to the Depository's instructions on behalf of the Depository to, and
deposited with, the Certificate Custodian, and all other Classes of Certificates
shall initially be issued in definitive, fully-registered form.

            The Certificates shall be executed by manual or facsimile signature
on behalf of the Securities Administrator by an authorized officer or signatory.
Certificates bearing the manual or facsimile signatures of individuals who were,
at the time when such signatures were affixed, authorized to sign on behalf of
the Securities Administrator shall bind the Securities Administrator,
notwithstanding that such individuals or any of them have ceased to be so
authorized prior to the execution and delivery of such Certificates or did not
hold such offices or positions at the date of such Certificate. No Certificate
shall be entitled to any benefit under this Agreement, or be valid for any
purpose, unless such Certificate shall have been manually authenticated by the
Securities Administrator substantially in the form provided for herein, and such
authentication upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly authenticated and delivered
hereunder. All Certificates shall be dated the date of their authentication.

      Section 6.02 Registration of Transfer and Exchange of Certificates. (a)
The Securities Administrator shall cause to be kept at an office or agency in
the city in which the Corporate Trust Office of the Securities Administrator is
located a Certificate Register in which, subject to such reasonable regulations
as it may prescribe, the Securities Administrator shall provide for the
registration of Certificates and of transfers and exchanges of Certificates as
herein provided. The Securities Administrator shall initially serve as
Certificate Registrar for the purpose of registering Certificates and transfers
and exchanges of Certificates as herein provided.

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

            (c) (i) Except as provided in paragraph (c)(iii) below, the
Book-Entry Certificates shall at all times remain registered in the name of the
Depository or its nominee and at all times: (A) registration of the Book-Entry
Certificates may not be transferred by the Securities Administrator except to
another Depository; (B) the Depository shall maintain book-entry records with
respect to the Certificate Owners and with respect to ownership and transfers of
such Book-Entry Certificates; (C) ownership and transfers of registration of the
Book-Entry Certificates on the books of the Depository shall be governed by
applicable rules established by the Depository; (D) the Depository may collect
its usual and customary fees, charges and expenses from its Depository
Participants; (E) the Securities Administrator shall deal with the Depository as
the representative of the Certificate Owners of the Book-Entry Certificates for
purposes of exercising the rights of Holders under this Agreement, and requests
and directions for and votes of the Depository shall not be deemed to be
inconsistent if they are made with respect to different Certificate Owners; and
(F) the Securities Administrator may rely and shall be fully protected in
relying upon information furnished by the Depository with respect to its
Depository Participants and furnished by the Depository Participants with
respect to indirect participating firms and persons shown on the books of such
indirect participating firms as direct or indirect Certificate Owners.

            (ii) All transfers by Certificate Owners of Book-Entry Certificates
      shall be made in accordance with the procedures established by the
       Depository Participant or brokerage firm representing such Certificate
      Owner. Each Depository Participant shall only transfer Book-Entry
      Certificates of Certificate Owners it represents or of brokerage firms for
      which it acts as agent in accordance with the Depository's normal
      procedures.

            (iii) If the Depository advises the Securities Administrator in
      writing that the Depository is no longer willing or able to properly
      discharge its responsibilities as Depository and the Securities
      Administrator or the Depositor is unable to locate a qualified successor,
      the Securities Administrator shall notify all Certificate Owners, through
      the Depository, of the occurrence of such event and of the availability of
      definitive, fully-registered Certificates (the "Definitive Certificates")
      to such Certificate Owners requesting the same. Upon surrender to the
      Securities Administrator of the related Class of Certificates by the
      Depository (or by the Certificate Custodian, if it holds such Class on
      behalf of the Depository), accompanied by the instructions from the
      Depository for registration, the Securities Administrator shall issue the
      Definitive Certificates. None of the Master Servicer, the Depositor, the
      Securities Administrator or the Trustee shall be liable for any delay in
      delivery of such instruction and may conclusively rely on, and shall be
      protected in relying on, such instructions. The Depositor shall provide
      the Securities Administrator with an adequate inventory of certificates to
      facilitate the issuance and transfer of Definitive Certificates. Upon the
      issuance of Definitive Certificates, the Securities Administrator shall
      recognize the Holders of the Definitive Certificates as Certificateholders
      hereunder.

            (d) No transfer of a Private Certificate shall be made unless such
transfer is exempt from the registration requirements of the 1933 Act and any
applicable state securities laws or is made in accordance with the 1933 Act and
such laws. In the event of any such transfer, (i) unless such transfer is made
in reliance on Rule 144A under the 1933 Act, the Securities Administrator or the
Depositor may require a written Opinion of Counsel (which may be in-house
counsel) acceptable to and in form and substance reasonably satisfactory to the
Securities Administrator and the Depositor that such transfer may be made
pursuant to an exemption, describing the applicable exemption and the basis
therefor, from the 1933 Act and such laws or is being made pursuant to the 1933
Act and such laws, which Opinion of Counsel shall not be an expense of the
Securities Administrator or the Depositor and (ii) the Securities Administrator
shall require a certificate from the Certificateholder desiring to effect such
transfer substantially in the form attached hereto as Exhibit G-1 and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached hereto either as Exhibit G-2A or as Exhibit G-2B, which
certificates shall not be an expense of the Securities Administrator or the
Depositor; provided that the foregoing requirements under clauses (i) and (ii)
shall not apply to a transfer of a Private Certificate between or among the
Depositor, the Seller, their affiliates or both. The Depositor shall provide to
any Holder of a Private Certificate and any prospective transferees designated
by any such Holder, information regarding the related Certificates and the
Mortgage Loans and such other information as shall be necessary to satisfy the
condition to eligibility set forth in Rule 144A(d)(4) for transfer of any such
certificate without registration thereof under the 1933 Act pursuant to the
registration exemption provided by Rule 144A. The Holder of a Private
Certificate desiring to effect such transfer shall, and does hereby agree to,
indemnify the Securities Administrator and the Depositor against any liability
that may result if the transfer is not so exempt or is not made in accordance
with such federal and state laws.

            (e) No transfer of an ERISA Restricted Certificate shall be made
unless the transferee delivers to the Securities Administrator either (i) a
representation letter in the form attached hereto as Exhibit H from the
transferee of such Certificate, which representation letter shall not be an
expense of the Depositor, the Trustee, the Securities Administrator or the
Master Servicer, or (ii) in the case of any ERISA Restricted Certificate
presented for registration in the name of an employee benefit plan or
arrangement, including an individual retirement account, subject to ERISA, the
Code, or any federal, state or local law ("Similar Law") which is similar to
ERISA or the Code (collectively, a "Plan"), or a trustee or custodian of any of
the foregoing, an Opinion of Counsel in form and substance satisfactory to the
Securities Administrator to the effect that the purchase or holding of such
ERISA Restricted Certificate by or on behalf of such Plan will not constitute or
result in a non-exempt prohibited transaction within the meaning of ERISA,
Section 4975 of the Code or Similar Law and will not subject the Trustee, the
Depositor, the Securities Administrator or the Master Servicer to any obligation
in addition to those undertaken in this Agreement, which Opinion of Counsel
shall not be an expense of the Securities Administrator, the Trustee or the
Master Servicer. Any transferee of an ERISA Restricted Certificate that does not
comply with either clause (i) or (ii) of the preceding sentence will be deemed
to have made one of the representations set forth in Exhibit H. For purposes of
clause (i) of the second preceding sentence, such representation shall be deemed
to have been made to the Certificate Registrar by the acceptance by a
Certificate Owner of a Book-Entry Certificate of the beneficial interest in any
such Class of ERISA-Restricted Certificates, unless the Certificate Registrar
shall have received from the transferee an alternative representation acceptable
in form and substance to the Depositor. Notwithstanding anything else to the
contrary herein, any purported transfer of an ERISA Restricted Certificate to or
on behalf of a Plan without the delivery to the Securities Administrator of an
Opinion of Counsel satisfactory to the Securities Administrator as described
above shall be void and of no effect.

            Neither the Securities Administrator nor the Certificate Registrar
shall have any liability for transfers of Book-Entry Certificates made through
the book-entry facilities of the Depository or between or among any Depository
Participants or Certificate Owners, made in violation of applicable
restrictions. The Securities Administrator may rely and shall be fully protected
in relying upon information furnished by the Depository with respect to its
Depository Participants and furnished by the Depository Participants with
respect to indirect participating firms and Persons shown on the books of such
indirect participating firms as direct or indirect Certificate Owners.

            To the extent permitted under applicable law (including, but not
limited to, ERISA), the Securities Administrator shall be under no liability to
any Person for any registration of transfer of any ERISA Restricted Certificate
that is in fact not permitted by this Section 6.02 or for making any payments
due on such Certificate to the Holder thereof or taking any other action with
respect to such Holder under the provisions of this Agreement so long as the
transfer was registered by the Securities Administrator in accordance with the
foregoing requirements.

            (f) Each Person who has or who acquires any Ownership Interest in a
Residual Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the following provisions, and
the rights of each Person acquiring any Ownership Interest in a Residual
Certificate are expressly subject to the following provisions:

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

            (ii) No Person shall acquire an Ownership Interest in a Residual
      Certificate unless such Ownership Interest is a pro rata undivided
      interest.

            (iii) In connection with any proposed transfer of any Ownership
      Interest in a Residual Certificate, the Securities Administrator shall
      require delivery to it, in form and substance satisfactory to it, of an
      affidavit in the form attached hereto as Exhibit I from the proposed
      transferee.

            (iv) Notwithstanding the delivery of an affidavit by a proposed
      transferee under clause (iii) above, if a Responsible Officer of the
      Securities Administrator has actual knowledge that the proposed transferee
      is not a Permitted Transferee, no transfer of any Ownership Interest in a
      Residual Certificate to such proposed transferee shall be effected.

            (v) No Ownership Interest in a Residual Certificate may be purchased
      by or transferred to any Person that is not a U.S. Person, unless (A) such
      Person holds such Residual Certificate in connection with the conduct of a
      trade or business within the United States and furnishes the transferor
      and the Securities Administrator with an effective Internal Revenue
       Service Form W-8ECI (or successor thereto) or (B) the transferee delivers
      to both the transferor and the Securities Administrator an Opinion of
      Counsel from a nationally-recognized tax counsel to the effect that such
      transfer is in accordance with the requirements of the Code and the
      regulations promulgated thereunder and that such transfer of a Residual
      Certificate will not be disregarded for federal income tax purposes.

            (vi) Any attempted or purported transfer of any Ownership Interest
      in a Residual Certificate in violation of the provisions of this Section
      6.02 shall be absolutely null and void and shall vest no rights in the
      purported transferee. If any purported transferee shall, in violation of
      the provisions of this Section 6.02, become a Holder of a Residual
      Certificate, then the prior Holder of such Residual Certificate that is a
      Permitted Transferee shall, upon discovery that the registration of
      transfer of such Residual Certificate was not in fact permitted by this
      Section 6.02, be restored to all rights as Holder thereof retroactive to
      the date of registration of transfer of such Residual Certificate. The
      Securities Administrator shall be under no liability to any Person for any
      registration of transfer of a Residual Certificate that is in fact not
      permitted by this Section 6.02 or for making any distributions due on such
      Residual Certificate to the Holder thereof or taking any other action with
      respect to such Holder under the provisions of the Agreement so long as
      the transfer was registered in accordance with this Section 6.02. The
      Securities Administrator shall be entitled to recover from any Holder of a
       Residual Certificate that was in fact not a Permitted Transferee at the
      time such distributions were made all distributions made on such Residual
      Certificate. Any such distributions so recovered by the Securities
      Administrator shall be distributed and delivered by the Securities
      Administrator to the prior Holder of such Residual Certificate that is a
      Permitted Transferee.

            (vii) If any Person other than a Permitted Transferee acquires any
      Ownership Interest in a Residual Certificate in violation of the
      restrictions in this Section 6.02, then the Securities Administrator,
      based on information provided to the Securities Administrator by the
      Master Servicer, will provide to the Internal Revenue Service, and to the
      Persons specified in Section 860E(e)(3) and (6) of the Code, information
      needed to compute the tax imposed under Section 860E(e) of the Code on
      transfers of residual interests to disqualified organizations. The
       expenses of the Securities Administrator under this clause (vii) shall be
      reimbursable by the Trust.

            (viii) No Ownership Interest in a Residual Certificate shall be
      acquired by a Plan or any Person acting on behalf of a Plan.

             (g) No service charge shall be imposed for any transfer or exchange
of Certificates of any Class, but the Securities Administrator may require
payment of a sum sufficient to cover any tax or governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            (h) All Certificates surrendered for transfer and exchange shall be
destroyed by the Certificate Registrar.

      Section 6.03 Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any
mutilated Certificate is surrendered to the Certificate Registrar or the
Certificate Registrar receives evidence to its satisfaction of the destruction,
loss or theft of any Certificate, and (b) there is delivered to the Securities
Administrator, the Trustee, the Depositor and the Certificate Registrar such
security or indemnity reasonably satisfactory to each, to save each of them
harmless, then, in the absence of actual notice to the Securities Administrator
or the Certificate Registrar that such Certificate has been acquired by a bona
fide purchaser, the Securities Administrator shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate of like tenor, Class and Percentage Interest but
bearing a number not contemporaneously outstanding. Upon the issuance of any new
Certificate under this Section, the Securities Administrator may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses (including the fees
and expenses of the Securities Administrator and the Certificate Registrar)
connected therewith. Any duplicate Certificate issued pursuant to this Section
shall constitute complete and indefeasible evidence of ownership in the Trust,
as if originally issued, whether or not the lost, stolen or destroyed
Certificate shall be found at any time.

      Section 6.04 Persons Deemed Owners.Prior to due presentation of a
Certificate for registration of transfer, the Depositor, the Master Servicer,
the Trustee, the Securities Administrator, the Certificate Registrar and any
agent of the Depositor, the Master Servicer, the Trustee, the Securities
Administrator or the Certificate Registrar may treat the Person in whose name
any Certificate is registered as the owner of such Certificate for the purpose
of receiving distributions pursuant to Section 5.01 and for all other purposes
whatsoever, and none of the Depositor, the Master Servicer, the Trustee, the
Securities Administrator, the Certificate Registrar or any agent of the
Depositor, the Master Servicer, the Trustee, the Securities Administrator or the
Certificate Registrar shall be affected by notice to the contrary.

                                  ARTICLE VII

                      THE DEPOSITOR AND THE MASTER SERVICER

      Section 7.01 Respective Liabilities of the Depositor and the Master
Servicer.The Depositor and the Master Servicer shall each be liable in
accordance herewith only to the extent of the obligations specifically and
respectively imposed upon and undertaken by the Depositor and the Master
Servicer herein. By way of illustration and not limitation, the Depositor is not
liable for the master servicing and administration of the Mortgage Loans, nor is
it obligated by Section 8.01 to assume any obligations of the Master Servicer or
to appoint a designee to assume such obligations, nor is it liable for any other
obligation hereunder that it may, but is not obligated to, assume unless it
elects to assume such obligation in accordance herewith.

      Section 7.02 Merger or Consolidation of the Depositor or the Master
Servicer.The Depositor and the Master Servicer will each keep in full effect its
existence, rights and franchises as a separate entity under the laws governing
its organization, and will each obtain and preserve its qualification to do
business as a foreign corporation in each jurisdiction in which such
qualification is or shall be necessary to protect the validity and
enforceability of this Agreement, the Certificates or any of the Mortgage Loans
and to perform its respective duties under this Agreement.

            Any Person into which the Depositor or the Master Servicer may be
merged or consolidated, or any corporation resulting from any merger or
consolidation to which the Depositor or the Master Servicer shall be a party, or
any Person succeeding to the business of the Depositor or the Master Servicer,
shall be the successor of the Depositor or the Master Servicer, as the case may
be, hereunder, without the execution or filing of any paper or any further act
on the part of any of the parties hereto, anything herein to the contrary
notwithstanding; provided, however, that the successor or surviving Person to
the Master Servicer shall be qualified to service mortgage loans on behalf of
Fannie Mae or Freddie Mac.

      Section 7.03 Limitation on Liability of the Depositor, the Master Servicer
and Others.None of the Depositor, the Master Servicer or any of the directors,
officers, employees or agents of the Depositor or of the Master Servicer shall
be under any liability to the Trust Estate or the Certificateholders for any
action taken or for refraining from the taking of any action in good faith
pursuant to this Agreement, or for errors in judgment; provided, however, that
this provision shall not protect the Depositor, the Master Servicer or any such
Person against any breach of warranties or representations made herein or any
liability which would otherwise be imposed by reason of willful misfeasance, bad
faith or gross negligence in the performance of duties or by reason of reckless
disregard of obligations and duties hereunder. The Depositor, the Master
Servicer and any director, officer, employee or agent of the Depositor or the
Master Servicer may rely in good faith on any document of any kind prima facie
properly executed and submitted by any Person respecting any matters arising
hereunder. The Depositor, the Master Servicer and any director, officer,
employee or agent of the Depositor or the Master Servicer shall be indemnified
by the Trust Estate and held harmless against any loss, liability or expense
incurred in connection with any legal action relating to this Agreement or the
Certificates, other than any loss, liability or expense related to any specific
Mortgage Loan or Mortgage Loans (except as any such loss, liability or expense
shall be otherwise reimbursable pursuant to this Agreement) and any loss,
liability or expense incurred by reason of willful misfeasance, bad faith or
gross negligence in the performance of duties hereunder or by reason of reckless
disregard of obligations and duties hereunder. Neither of the Depositor nor the
Master Servicer shall be under any obligation to appear in, prosecute or defend
any legal action which is not incidental to its respective duties under this
Agreement and which in its opinion may involve it in any expense or liability;
provided, however, that the Depositor or the Master Servicer may in its
discretion undertake any such action which it may deem necessary or desirable in
respect to this Agreement and the rights and duties of the parties hereto and
the interests of the Certificateholders hereunder. In such event, the legal
expenses and costs of such action and any liability resulting therefrom shall be
expenses, costs and liabilities of the Trust Estate (except any expenses, costs
or liabilities incurred as a result of any breach of representations or
warranties of the related party or by reason of willful misfeasance, bad faith
or gross negligence in the performance of duties of such party hereunder or by
reason of reckless disregard of obligations and duties of such party hereunder),
and the Depositor and the Master Servicer shall each be entitled to be
reimbursed therefor out of amounts attributable to the Mortgage Loans on deposit
in the Master Servicer Custodial Account as provided by Section 3.11.

      Section 7.04 Depositor and Master Servicer Not to Resign.Subject to the
provisions of Section 7.02, neither the Depositor nor the Master Servicer shall
resign from its respective obligations and duties hereby imposed on it except
upon determination that its duties hereunder are no longer permissible under
applicable law. Any such determination permitting the resignation of the
Depositor or the Master Servicer shall be evidenced by an Opinion of Counsel to
such effect delivered to the Securities Administrator. No such resignation by
the Master Servicer shall become effective until the Securities Administrator or
a successor Master Servicer shall have assumed such Master Servicer's
responsibilities and obligations in accordance with Section 8.05 hereof.

                                  ARTICLE VIII

                                     DEFAULT

      Section 8.01 Events of Default.If any one of the following events ("Events
of Default") shall occur and be continuing:

            (a) any failure by the Master Servicer to remit amounts to the
Securities Administrator for deposit into the Certificate Account in the amount
and manner provided herein so as to enable the Securities Administrator to
distribute to Holders of Certificates any payment required to be made under the
terms of such Certificates and this Agreement which continues unremedied by 3:00
P.M. New York time on the related Distribution Date; or

            (b) failure on the part of the Master Servicer duly to observe or
perform in any material respect any other covenants or agreements of the Master
Servicer set forth in the Certificates or in this Agreement, which covenants and
agreements continue unremedied for a period of 30 days after the date on which
written notice of such failure, requiring the same to be remedied, shall have
been given to the Master Servicer by the Securities Administrator, the Trustee
or the Depositor, or to the Master Servicer, the Depositor, the Securities
Administrator and the Trustee by the Holders of Certificates evidencing Voting
Rights aggregating not less than 25% of all Certificates affected thereby; or

            (c) the entry of a decree or order by a court or agency or
supervisory authority having jurisdiction in the premises for the appointment of
a conservator, receiver or liquidator in any insolvency, readjustment of debt,
marshalling of assets and liabilities or similar proceedings against the Master
Servicer, or for the winding up or liquidation of the Master Servicer's affairs,
and the continuance of any such decree or order unstayed and in effect for a
period of 60 consecutive days; or

            (d) the consent by the Master Servicer to the appointment of a
conservator or receiver or liquidator in any insolvency, readjustment of debt,
marshalling of assets and liabilities or similar proceedings of or relating to
the Master Servicer or of or relating to substantially all of its property; or
the Master Servicer shall admit in writing its inability to pay its debts
generally as they become due, file a petition to take advantage of any
applicable insolvency or reorganization statute, make an assignment for the
benefit of its creditors, or voluntarily suspend payment of its obligations;

then, and in each and every such case, so long as an Event of Default is
actually known by the Trustee or the Depositor and shall not have been remedied
by the Master Servicer, either the Trustee or the Depositor may, and at the
direction of the Holders of Certificates evidencing Voting Rights aggregating
not less than 51% of all Certificates affected thereby shall, by notice then
given in writing to the Master Servicer (and to the Trustee, if given by the
Depositor, and to the Depositor, if given by the Trustee), terminate all of the
rights and obligations of the Master Servicer under this Agreement. On or after
the receipt by the Master Servicer of such written notice and subject to Section
8.05, all authority and power of the Master Servicer under this Agreement,
whether with respect to the Certificates or the Mortgage Loans or otherwise,
shall pass to and be vested in the Trustee pursuant to and under this Section
8.01 and Section 8.05(a), unless and until such time as the Trustee shall
appoint a successor Master Servicer pursuant to Section 8.05, and, without
limitation, the Trustee is hereby authorized and empowered to execute and
deliver, on behalf of the Master Servicer, as attorney-in-fact or otherwise, any
and all documents and other instruments, and to do or accomplish all other acts
or things necessary or appropriate to effect the purposes of such notice of
termination, whether to complete the transfer and endorsement of the applicable
Mortgage Loans and related documents, or otherwise, including, without
limitation, the recordation of the assignments of the applicable Mortgage Loans
to it. The Master Servicer agrees to cooperate with the Trustee in effecting the
termination of the responsibilities and rights of the Master Servicer hereunder,
including, without limitation, the transfer to the Trustee for the
administration by it of all cash amounts that have been deposited by the Master
Servicer in the Master Servicer Custodial Account or thereafter received by the
Master Servicer with respect to the Mortgage Loans. Upon obtaining notice or
knowledge of the occurrence of any Event of Default, the Person obtaining such
notice or knowledge shall give prompt written notice thereof to
Certificateholders at their respective addresses appearing in the Certificate
Register and to each Rating Agency. All costs and expenses (including attorneys'
fees) incurred in connection with transferring the master servicing data and
information to the successor Master Servicer and amending this Agreement to
reflect such succession as Master Servicer pursuant to this Section 8.01 shall
be paid by the predecessor Master Servicer. Notwithstanding the termination of
the Master Servicer pursuant hereto, the Master Servicer shall remain liable for
any causes of action arising out of any Event of Default occurring prior to such
termination, subject to the terms and conditions of this Agreement.

      Section 8.02 Remedies of Trustee.During the continuance of any Event of
Default, so long as such Event of Default shall not have been remedied, the
Trustee, in addition to the rights specified in Section 8.01, shall have the
right, in its own name as trustee of an express trust, to take all actions now
or hereafter existing at law, in equity or by statute to enforce its rights and
remedies and to protect the interests, and enforce the rights and remedies, of
the Certificateholders (including the institution and prosecution of all
judicial, administrative and other proceedings and the filing of proofs of claim
and debt in connection therewith). Except as otherwise expressly provided in
this Agreement, no remedy provided for by this Agreement shall be exclusive of
any other remedy, and each and every remedy shall be cumulative and in addition
to any other remedy and no delay or omission to exercise any right or remedy
shall impair any such right or remedy or shall be deemed to be a waiver of any
Event of Default.

      Section 8.03 Directions by Certificateholders and Duties of Trustee During
Event of Default.During the continuance of any Event of Default, Holders of
Certificates evidencing Voting Rights aggregating not less than 25% (or such
other percentage as may be required herein) of each Class of Certificates
affected thereby may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred upon the Trustee under this Agreement; provided, however, that
the Trustee shall be under no obligation to pursue any such remedy, or to
exercise any of the trusts or powers vested in it by this Agreement (including,
without limitation, (a) the conducting or defending of any administrative action
or litigation hereunder or in relation hereto, and (b) the terminating of the
Master Servicer or any successor Master Servicer from its rights and duties as
servicer hereunder) at the request, order or direction of any of the
Certificateholders, unless such Certificateholders shall have offered to the
Trustee reasonable security or indemnity satisfactory to it against the costs,
expenses and liabilities which may be incurred therein or thereby and, provided
further, that, subject to the provisions of Section 9.01, the Trustee shall have
the right to decline to follow any such direction if the Trustee, based upon an
Opinion of Counsel, determines that the action or proceeding so directed may not
lawfully be taken or if the Trustee in good faith determines that the action or
proceeding so directed would subject the Trustee to a risk of personal liability
or be unjustly prejudicial to the non-assenting Certificateholders.

      Section 8.04 Action upon Certain Failures of the Master Servicer and upon
Event of Default.In the event that a Responsible Officer of the Trustee shall
have actual knowledge of any failure of the Master Servicer specified in Section
8.01(a) or (b) which would become an Event of Default upon such Master
Servicer's failure to remedy the same after notice, the Trustee shall give
notice thereof to the Master Servicer. If a Responsible Officer of the Trustee
shall have knowledge of an Event of Default, the Trustee shall give prompt
written notice thereof to the Certificateholders in accordance with Section
8.01.

      Section 8.05 Trustee to Act; Appointment of Successor.(a) Within 90 days
of the time the Master Servicer (and the Trustee if such notice of termination
is delivered by the Depositor) receives a notice of termination pursuant to
Section 8.01, the Trustee (or other named successor) shall be the successor in
all respects to the Master Servicer in its capacity as master servicer under
this Agreement and the transactions set forth or provided for herein and shall
be subject to all the responsibilities, duties and liabilities relating thereto
placed on the Master Servicer by the terms and provisions hereof and thereof, as
applicable, or shall appoint a successor pursuant to Section 3.07.
Notwithstanding the foregoing, (i) the parties hereto agree that the Trustee, in
its capacity as successor Master Servicer, immediately will assume all of the
obligations of the Master Servicer to make advances (including, without
limitation, Advances pursuant to Section 3.21) under this Agreement, (ii) the
Trustee, in its capacity as successor Master Servicer, shall not be responsible
for the lack of information and/or documents that it cannot obtain through
reasonable efforts and (iii) under no circumstances shall any provision of this
Agreement be construed to require the Trustee, acting in its capacity as
successor to the Master Servicer in its obligation to make advances (including
Advances pursuant to Section 3.21) to advance, expend or risk its own funds or
otherwise incur any financial liability in the performance of its duties
hereunder if it shall have reasonable grounds for believing that such funds are
non-recoverable. Subject to Section 8.05(b), as compensation therefor, the
Trustee shall be entitled to such compensation as the terminated Master Servicer
would have been entitled to hereunder if no such notice of termination had been
given, except for those amounts due to the Master Servicer as reimbursement for
Advances previously made or amounts previously expended and are otherwise
reimbursable hereunder. Notwithstanding the above, the Trustee may, if it shall
be unwilling so to act, or shall, if it is legally unable so to act, appoint, or
petition a court of competent jurisdiction to appoint, any established housing
and home finance institution having a net worth of not less than $10,000,000 as
the successor to the terminated Master Servicer hereunder in the assumption of
all or any part of the responsibilities, duties or liabilities of the Master
Servicer hereunder; provided, however, that any such institution appointed as a
successor Master Servicer shall not, as evidenced in writing by each Rating
Agency, adversely affect the then current rating of any Class of Certificates
immediately prior to the termination of the terminated Master Servicer. The
appointment of a successor Master Servicer shall not affect any liability of the
predecessor Master Servicer which may have arisen under this Agreement prior to
its termination as Master Servicer, nor shall any successor
