                         POOLING AND SERVICING AGREEMENT

            THIS POOLING AND SERVICING AGREEMENT, dated September 28, 2006, is
hereby executed by and among BANC OF AMERICA MORTGAGE SECURITIES, INC., as
depositor (together with its permitted successors and assigns, the "Depositor"),
BANK OF AMERICA, NATIONAL ASSOCIATION, as servicer (together with its permitted
successors and assigns, the "Servicer"), and WELLS FARGO BANK, N.A., 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 Servicer and the Trustee agree as follows:

                              PRELIMINARY STATEMENT

            The Depositor intends to sell pass-through certificates
(collectively, the "Certificates"), to be issued hereunder in multiple Classes,
which in the aggregate will evidence the entire beneficial ownership interest in
the Trust created hereunder. The Certificates will consist of thirteen Classes
of Certificates, designated as (i) the Class A-1, Class A-2, Class A-3, Class
A-4, Class A-5 and Class A-6 Certificates, (ii) the Class M-1, Class M-2, Class
M-3, Class M-4 and Class M-5 Certificates, (iii) the Class CE Certificates and
(iv) the Class R Certificate. The portion of the Trust Estate consisting of the
Cap Carryover Reserve Account and the right of the Offered Certificates to
receive amounts from the Cap Carryover Reserve Account shall not be assets of
either REMIC created hereunder, but rather shall be assets of the Grantor Trust.

                                      REMIC 1

            As provided herein, the Trustee will make an election to treat the
segregated pool of assets consisting of the Mortgage Loans and certain other
related assets subject to this Agreement (but exclusive of the Cap Carryover
Amounts and the Cap Carryover Reserve Account) as a real estate investment
conduit (a "REMIC") for federal income tax purposes, and such segregated pool of
assets will be designated as "REMIC 1." The Class R-1 Interest will represent
the sole class of "residual interests" in REMIC 1 for purposes of the REMIC
Provisions under federal income tax law. The following table irrevocably sets
forth the designation, the Uncertificated REMIC 1 Pass-Through Rate, the initial
Uncertificated Principal Balance, and solely for purposes of satisfying Treasury
Regulations Section 1.860G-1(a)(4)(iii), the "latest possible maturity date" for
each of the REMIC 1 Regular Interests. None of the REMIC 1 Regular Interests
will be certificated.

                          CONVEYANCE OF MORTGAGE LOANS
                        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, including all
interest and principal received on or with respect to the Mortgage Loans (other
than payments of principal and interest due and payable on the Mortgage Loans on
or before the Cut-off Date). The foregoing sale, transfer, assignment and set
over does not and is not intended to result in a creation of an assumption by
the Trustee of any obligation of the Depositor or any other Person in connection
with the Mortgage Loans or any agreement or instrument relating thereto, except
as specifically set forth herein. In addition, 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, the Depositor's rights to receive any
BPP Mortgage Loan Payment. It is agreed and understood by the parties hereto
that it is not intended that any mortgage loan be included in the Trust that is
a "High-Cost Home Loan" as defined in any of (i) the New Jersey Home Ownership
Act effective November 27, 2003, (ii) the New Mexico Home Loan Protection Act
effective January 1, 2004, (iii) the Massachusetts Predatory Home Loan Practices
Act effective November 7, 2004 or (iv) the Indiana Home Loan Practices Act,

            (b) In connection with such transfer and assignment, the Depositor
   shall deliver or cause to be delivered to the Trustee, for the benefit of the
   Certificateholders, the following documents or instruments with respect to
   each Mortgage Loan so assigned:

            (i) the original Mortgage Note, endorsed by manual or facsimile
      signature in the following form: "Pay to the order of Wells Fargo Bank,
       N.A., as trustee for the holders of the Banc of America Alternative Loan
      Trust 2006-7 Mortgage Pass-Through Certificates, Series 2006-7, without
      recourse," with all necessary intervening endorsements showing a complete
      chain of endorsement from the originator to the Trustee (each such
      endorsement being sufficient to transfer all right, title and interest of
      the party so endorsing, as noteholder or assignee thereof, in and to that
      Mortgage Note);

            (ii) except as provided below, the original recorded Mortgage with
      evidence of a recording thereon, or if any such Mortgage has not been
      returned from the applicable recording office or has been lost, or if such
      public recording office retains the original recorded Mortgage, a copy of
      such Mortgage certified by the Depositor as being a true and correct copy
      of the Mortgage;

            (iii) subject to the provisos at the end of this paragraph, a duly
      executed Assignment of Mortgage to "Wells Fargo Bank, N.A., as trustee for
      the holders of the Banc of America Alternative Loan Trust 2006-7 Mortgage
      Pass-Through Certificates, Series 2006-7" (which may be included in a
      blanket assignment or assignments), together with, except as provided
      below, originals of all interim recorded assignments of such mortgage or a
      copy of such interim assignment certified by the Depositor as being a true
      and complete copy of the original recorded intervening assignments of
      Mortgage (each such assignment, when duly and validly completed, to be in
      recordable form and sufficient to effect the assignment of and transfer to
      the assignee thereof, under the Mortgage to which the assignment relates);
      provided that, if the related Mortgage has not been returned from the
      applicable public recording office, such Assignment of Mortgage may
      exclude the information to be provided by the recording office; and
      provided, further, if the related Mortgage has been recorded in the name
      of Mortgage Electronic Registration Systems, Inc. ("MERS") or its
      designee, no Assignment of Mortgage in favor of the Trustee will be
      required to be prepared or delivered and instead, the Servicer shall take
      all actions as are necessary to cause the Trust to be shown as the owner
      of the related Mortgage Loan on the records of MERS for purposes of the
      system of recording transfers of beneficial ownership of mortgages
      maintained by MERS;

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

            (v) any of (A) the original or duplicate original mortgagee title
      insurance policy and all riders thereto, (B) a title search showing no
      lien (other than standard exceptions of the type described in Section 2.04
      (viii)) on the Mortgaged Property senior to the lien of the Mortgage or
      (C) an opinion of counsel of the type customarily rendered in the
      applicable jurisdiction in lieu of a title insurance policy;

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

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

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

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

                  (A) The stock certificate;

                  (B) The stock power executed in blank;

                  (C) The executed proprietary lease;

                  (D) The executed recognition agreement;

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

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

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

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

            If in connection with any Mortgage Loans, the Depositor cannot
deliver (A) the Mortgage, (B) all interim recorded assignments, (C) all
assumption, modification, consolidation or extension agreements, if any, or (D)
the lender's title policy, if any, (together with all riders thereto) 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
any, has not been delivered to either the Servicer or the Depositor by the
applicable title insurer in the case of clause (v) above, the Depositor shall
promptly deliver or cause to be delivered to the Trustee or 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 year following the Closing Date, unless, in
the case of clause (ii), (iii) or (iv) above, there has been a continuing delay
at the applicable recording office or, in the case of clause (v), there has been
a continuing delay at the applicable insurer and the Depositor has delivered the
Officer's Certificate to such effect to the Trustee. The Depositor shall forward
or cause to be forwarded to the Trustee (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 Trustee or 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 Servicer 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.

            As promptly as practicable subsequent to such transfer and
assignment, and in any event, within 30 days thereafter, the Servicer shall
(except for any Mortgage which has been recorded in the name of MERS or its
designee) (I) cause each Assignment of Mortgage to be in proper form for
recording in the appropriate public office for real property records within 30
days of the Closing Date and (II) at the Depositor's expense, cause to be
delivered for recording in the appropriate public office for real property
records the Assignments of the Mortgages to the Trustee, except that, with
respect to any Assignment of a Mortgage as to which the 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 any
event within 30 days after the receipt thereof and, no recording of an
Assignment of Mortgage will be required in a state if either (i) the Depositor
furnishes to the Trustee an unqualified Opinion of Counsel reasonably acceptable
to the Trustee 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. Set forth on
Exhibit L attached hereto is a list of all states where recordation is required
by either Rating Agency to obtain the initial ratings of the Certificates. The
Trustee may rely and shall be protected in relying upon the information
contained in such Exhibit L.

            In the case of Mortgage Loans that have been prepaid in full as of
the Closing Date, the Depositor, in lieu of delivering the above documents to
the Trustee, or the Custodian on the Trustee's behalf, will cause the Servicer
to deposit in the Servicer Custodial Account the portion of such payment that is
required to be deposited in the Servicer Custodial Account pursuant to Section
3.08.

            Section 2.02 Acceptance by the Trustee of the Mortgage Loans.
Subject to the provisions of the following paragraph, the Trustee declares that
it, or the Custodian as its agent, 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, in trust for the exclusive use and benefit of all present and future
Certificateholders. Upon execution and delivery of this document, the Trustee
shall deliver or cause the Custodian to deliver to the Depositor, the Trustee
and the Servicer a certification in the form of Exhibit M hereto (the "Initial
Certification") to the effect that, except as may be specified in a list of
exceptions attached thereto, it 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 Trustee shall review, or cause the Custodian to review, the Mortgage Files
in its possession, and shall deliver to the Depositor, the Trustee and the
Servicer a certification in the form of Exhibit N hereto (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).

            If, in the course of such review, the Trustee or 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, the Trustee
shall promptly so notify the Servicer and the Depositor, or shall cause the
Custodian to promptly so notify the Servicer and the Depositor. In performing
any such review, the Trustee or the Custodian may conclusively rely on the
purported genuineness of any such document and any signature thereon. It is
understood that the scope of the Trustee's or 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. Neither the Trustee nor the Custodian shall have any
responsibility for determining whether any document is valid and binding,
whether the text of any assignment or endorsement is in proper or recordable
form, whether any document has been recorded in accordance with the requirements
of any applicable jurisdiction, or whether a blanket assignment is permitted in
any applicable jurisdiction. The Depositor hereby covenants and agrees that it
will promptly correct or cure such defect within 90 days from the date it was so
notified of such defect and, if the Depositor does not correct or cure such
defect within such period, the Depositor will either (a) substitute for the
related Mortgage Loan a Substitute Mortgage Loan, which substitution shall be
accomplished in the manner and subject to the conditions set forth below or (b)
purchase such Mortgage Loan from the Trustee at the Repurchase Price for such
Mortgage Loan; provided, however, that in no event shall such a substitution
occur more than two years from the Closing Date; provided, further, that such
substitution or repurchase shall occur within 90 days of when such defect was
discovered if such defect will cause the Mortgage Loan not to be a "qualified
mortgage" within the meaning of Section 860G(a)(3) of the Code.

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

            The 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 Servicer shall deliver the amended Mortgage Loan Schedule
to the Trustee and the Custodian. Upon such substitution, each Substitute
Mortgage Loan shall be subject to the terms of this Agreement in all respects,
and the Depositor shall be deemed to have made to the Trustee with respect to
such Substitute Mortgage Loan, as of the date of substitution, the
representations and warranties made pursuant to Section 2.04. Upon any such
substitution and the deposit to the Servicer Custodial Account of any required
Substitution Adjustment Amount (as described in the next paragraph) and receipt
of a Request for Release, the Trustee shall release, or shall direct the
Custodian to release, the Mortgage File relating to such Defective Mortgage Loan
to the Depositor and shall execute and deliver at the Depositor's direction such
instruments of transfer or assignment prepared by the Depositor, in each case
without recourse, as shall be necessary to vest title in the Depositor, 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 Depositor 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 as of the date of substitution is less than the aggregate Stated
Principal Balance of all such Defective Mortgage Loans (after application of the
principal portion of the Monthly Payments due in the month of substitution) (the
"Substitution Adjustment Amount") plus an amount equal to the aggregate of any
unreimbursed Advances with respect to such Defective Mortgage Loans shall be
deposited into the Servicer Custodial Account by the Depositor on or before the
Remittance Date for the Distribution Date in the month succeeding the calendar
month during which the related Mortgage Loan is required to be purchased or
replaced hereunder.

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

            It is understood and agreed that the obligation of the Depositor to
substitute for or to purchase any Mortgage Loan which does not meet the
requirements of Section 2.01 shall constitute the sole remedy respecting such
defect available to the Trustee and any Certificateholder against the Depositor.

            The Trustee or the Custodian, on behalf of the Trustee, shall be
under no duty or obligation (i) to inspect, review or examine any such
documents, instruments, certificates or other papers to determine that they are
genuine, enforceable, or appropriate for the represented purpose or that they
are other than what they purport to be on their face or (ii) to determine
whether any Mortgage File should include any of the documents specified in
Section 2.01(b)(iv), (vi), (vii), (viii) and (ix). In connection with making the
certifications required hereunder, to the extent a title search or opinion of
counsel has been provided in lieu of a title policy for any Mortgage Loan, the
Trustee shall only be responsible for confirming that a title search or opinion
of counsel has been provided for such Mortgage Loan and shall not be deemed to
have certified that the content of such title search or opinion of counsel is
sufficient to meet the requirements of Section 2.01(b)(v).

            Section 2.03 Representations and Warranties of the Servicer. The
Servicer hereby makes the following representations and warranties to the
Depositor and the Trustee, as of the Closing Date:

            (i) The Servicer is a national banking association duly organized,
      validly existing, and in good standing under the federal 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 is located if
      the laws of such state require licensing or qualification in order to
      conduct business of the type conducted by the Servicer. The 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 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 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 creditors' rights generally or creditors of national
      banks 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 Servicer to make this Agreement valid and binding upon
      the 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 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 Servicer and will
      not result in the breach of any term or provision of the charter or
      by-laws of the 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 Servicer or its property
      is subject, or result in the violation of any law, rule, regulation,
      order, judgment or decree to which the Servicer or its property is
      subject.

            (iv) There is no action, suit, proceeding or investigation pending
      or, to the best knowledge of the Servicer, threatened against the 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 Servicer, or in any material impairment of the
      right or ability of the 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 Servicer contemplated herein, or
      which would materially impair the ability of the 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. Upon discovery by any of the Depositor,
the Servicer or the Trustee of a breach of any of the representations or
warranties set forth in this Section 2.03, the party discovering such breach
shall give prompt written notice to the other parties.

            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) The information set forth in the Mortgage Loan Schedule is true
      and correct in all material respects.

            (ii) There are no delinquent taxes, ground rents, governmental
      assessments, insurance premiums, leasehold payments, including assessments
      payable in future installments or other outstanding charges affecting the
      lien priority of the related Mortgaged Property.

            (iii) The terms of the Mortgage Note and the Mortgage have not been
      impaired, waived, altered or modified in any respect, except by written
       instruments, recorded in the applicable public recording office if
      necessary to maintain the lien priority of the Mortgage, and which have
      been delivered to the Trustee; the substance of any such waiver,
      alteration or modification has been approved by the insurer under the
      Primary Insurance Policy, if any, the title insurer, to the extent
      required by the related policy, and is reflected on the Mortgage Loan
      Schedule. No instrument of waiver, alteration or modification has been
      executed, and no Mortgagor has been released, in whole or in part, except
      in connection with an assumption agreement approved by the insurer under
      the Primary Insurance Policy, if any, the title insurer, to the extent
      required by the policy, and which assumption agreement has been delivered
      to the Trustee.

            (iv) The Mortgage Note and the Mortgage are not subject to any right
      of rescission, set-off, counterclaim or defense, including the defense of
       usury, nor will the operation of any of the terms of the Mortgage Note and
      the Mortgage, or the exercise of any right thereunder, render either the
      Mortgage Note or the Mortgage unenforceable, in whole or in part, or
      subject to any right of rescission, set-off, counterclaim or defense,
      including the defense of usury and no such right of rescission, set-off,
      counterclaim or defense has been asserted with respect thereto.

            (v) All buildings upon the Mortgaged Property are insured by an
      insurer generally acceptable to prudent mortgage lending institutions
      against loss by fire, hazards of extended coverage and such other hazards
      as are customary in the area the Mortgaged Property is located, pursuant
      to insurance policies conforming to the requirements of Customary
      Servicing Procedures and this Agreement. All such insurance policies
      contain a standard mortgagee clause naming the originator of the Mortgage
      Loan, its successors and assigns as mortgagee and all premiums thereon
      have been paid. If the Mortgaged Property is in an area identified on a
      flood hazard map or flood insurance rate map issued by the Federal
      Emergency Management Agency as having special flood hazards (and such
      flood insurance has been made available), a flood insurance policy meeting
      the requirements of the current guidelines of the Federal Insurance
      Administration is in effect which policy conforms to the requirements of
      Fannie Mae or Freddie Mac. The Mortgage obligates the Mortgagor thereunder
      to maintain all such insurance at the Mortgagor's cost and expense, and on
      the Mortgagor's failure to do so, authorizes the holder of the Mortgage to
      maintain such insurance at Mortgagor's cost and expense and to seek
      reimbursement therefor from the Mortgagor.

            (vi) Any and all requirements of any federal, state or local law
      including, without limitation, usury, truth in lending, real estate
      settlement procedures, consumer credit protections, all applicable
      predatory and abusive lending laws, equal credit opportunity or disclosure
      laws applicable to the origination and servicing of Mortgage Loan have
      been complied with.

            (vii) The Mortgage has not been satisfied, canceled, subordinated or
      rescinded, in whole or in part (other than as to Principal Prepayments in
      full which may have been received prior to the Closing Date), and the
      Mortgaged Property has not been released from the lien of the Mortgage, in
      whole or in part, nor has any instrument been executed that would effect
      any such satisfaction, cancellation, subordination, rescission or release.

            (viii) The Mortgage is a valid, existing and enforceable first lien
      on the Mortgaged Property, including all improvements on the Mortgaged
      Property subject only to (A) the lien of current real property taxes and
      assessments not yet due and payable, (B) covenants, conditions and
      restrictions, rights of way, easements and other matters of the public
      record as of the date of recording being acceptable to mortgage lending
      institutions generally and specifically referred to in the lender's title
      insurance policy delivered to the originator of the Mortgage Loan and
      which do not adversely affect the Appraised Value of the Mortgaged
      Property, (C) if the Mortgaged Property consists of Co-op Shares, any lien
      for amounts due to the cooperative housing corporation for unpaid
      assessments or charges or any lien of any assignment of rents or
      maintenance expenses secured by the real property owned by the cooperative
      housing corporation, and (D) other matters to which like properties are
      commonly subject which do not materially interfere with the benefits of
      the security intended to be provided by the Mortgage or the use,
      enjoyment, value or marketability of the related Mortgaged Property. Any
       security agreement, chattel mortgage or equivalent document related to and
      delivered in connection with the Mortgage Loan establishes and creates a
      valid, existing and enforceable first lien and first priority security
      interest on the property described therein and the Depositor has the full
      right to sell and assign the same to the Trustee.

            (ix) The Mortgage Note and the related Mortgage are genuine and each
      is the legal, valid and binding obligation of the maker thereof,
      enforceable in accordance with its terms 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.

            (x) All parties to the Mortgage Note and the Mortgage had legal
      capacity to enter into the Mortgage Loan and to execute and deliver the
      Mortgage Note and the Mortgage, and the Mortgage Note and the Mortgage
      have been duly and properly executed by such parties.

            (xi) The proceeds of the Mortgage Loan have been fully disbursed to
      or for the account of the Mortgagor and there is no obligation for the
      Mortgagee to advance additional funds thereunder and any and all
      requirements as to completion of any on-site or off-site improvements and
      as to disbursements of any escrow funds therefor have been complied with.
      All costs, fees and expenses incurred in making or closing the Mortgage
      Loan and the recording of the Mortgage have been paid, and the Mortgagor
      is not entitled to any refund of any amounts paid or due to the Mortgagee
      pursuant to the Mortgage Note or Mortgage.

            (xii) To the best of the Depositor's knowledge, all parties which
      have had any interest in the Mortgage Loan, whether as mortgagee,
      assignee, pledgee or otherwise, are (or, during the period in which they
      held and disposed of such interest, were) in compliance with any and all
      applicable "doing business" and licensing requirements of the laws of the
      state wherein the Mortgaged Property is located.

            (xiii) (A) The Mortgage Loan is covered by an ALTA lender's title
      insurance policy, acceptable to Fannie Mae or Freddie Mac, issued by a
      title insurer acceptable to Fannie Mae or Freddie Mac and qualified to do
      business in the jurisdiction where the Mortgaged Property is located,
      insuring (subject to the exceptions contained in (viii)(A) and (B) above)
      the Seller, its successors and assigns as to the first priority lien of
      the Mortgage in the original principal amount of the Mortgage Loan, (B) a
      title search has been done showing no lien (other than the exceptions
      contained in (viii)(A) and (B) above) on the related Mortgaged Property
      senior to the lien of the Mortgage or (C) in the case of any Mortgage Loan
      secured by a Mortgaged Property located in a jurisdiction where such
      policies are generally not available, an opinion of counsel of the type
      customarily rendered in such jurisdiction in lieu of title insurance is
      instead received. For each Mortgage Loan covered by a title insurance
      policy (x) the Depositor is the sole insured of such lender's title
      insurance policy, and such lender's title insurance policy is in full
      force and effect and will be in full force and effect upon the
      consummation of the transactions contemplated by this Agreement and (y) no
      claims have been made under such lender's title insurance policy, and the
      Depositor has not done, by act or omission, anything which would impair
      the coverage of such lender's title insurance policy.

            (xiv) There is no default, breach, violation or event of
      acceleration existing under the Mortgage or the Mortgage Note and no event
      which, with the passage of time or with notice and the expiration of any
      grace or cure period, would constitute a default, breach, violation or
      event of acceleration, and the Seller has not waived any default, breach,
      violation or event of acceleration.

            (xv) As of the date of origination of the Mortgage Loan, there had
      been no mechanics' or similar liens or claims filed for work, labor or
      material (and no rights are outstanding that under law could give rise to
      such lien) affecting the related Mortgaged Property which are or may be
      liens prior to, or equal or coordinate with, the lien of the related
      Mortgage.

            (xvi) All improvements which were considered in determining the
      Appraised Value of the related Mortgaged Property lay wholly within the
      boundaries and building restriction lines of the Mortgaged Property, and
      no improvements on adjoining properties encroach upon the Mortgaged
      Property.

            (xvii) The Mortgage Loan was originated by a savings and loan
      association, savings bank, commercial bank, credit union, insurance
      company, or similar institution which is supervised and examined by a
      federal or state authority, or by a mortgagee approved by the Secretary of
      Housing and Urban Development pursuant to sections 203 and 211 of the
      National Housing Act.

            (xviii) Principal payments on the Mortgage Loan commenced no more
      than sixty days after the proceeds of the Mortgaged Loan were disbursed.
      The Mortgage Loans are 20 to 30-year fixed rate mortgage loans having an
      original term to maturity of not more than 30 years, with interest payable
      in arrears on the first day of the month. Each Mortgage Note requires a
       monthly payment which is sufficient to fully amortize the original
      principal balance over the original term thereof and to pay interest at
      the related Mortgage Interest Rate. The Mortgage Note does not permit
      negative amortization.

            (xix) There is no proceeding pending or, to the Depositor's
      knowledge, threatened for the total or partial condemnation of the
      Mortgaged Property. The Mortgaged Property is in good repair and is
      undamaged by waste, fire, earthquake or earth movement, windstorm, flood,
      tornado or other casualty, so as to affect adversely the value of the
      Mortgaged Property as security for the Mortgage Loan or the use for which
      the premises were intended.

            (xx) The Mortgage and related Mortgage Note contain customary and
      enforceable provisions such as to render the rights and remedies of the
      holder thereof adequate for the realization against the Mortgaged Property
      of the benefits of the security provided thereby, including (A) in the
      case of a Mortgage designated as a deed of trust, by trustee's sale, and
      (B) otherwise by judicial foreclosure. To the best of the Depositor's
      knowledge, following the date of origination of the Mortgage Loan, the
      Mortgaged Property has not been subject to any bankruptcy proceeding or
      foreclosure proceeding and the Mortgagor has not filed for protection
      under applicable bankruptcy laws. There is no homestead or other exemption
      or right available to the Mortgagor or any other person which would
      interfere with the right to sell the Mortgaged Property at a trustee's
      sale or the right to foreclose the Mortgage.

            (xxi) Other than any Borrowers Protection Plan(R) addendum to the
      Mortgage Note of a BPP Mortgage Loan, the Mortgage Note and Mortgage are
      on forms acceptable to Fannie Mae or Freddie Mac.

            (xxii) The Mortgage Note is not and has not been secured by any
      collateral except the lien of the corresponding Mortgage on the Mortgaged
      Property and the security interest of any applicable security agreement or
      chattel mortgage referred to in (viii) above.

            (xxiii) Each appraisal of the related Mortgaged Property, is in a
      form acceptable to Fannie Mae or Freddie Mac and such appraisal complies
      with the requirements of FIRREA, and was made and signed, prior to the
      approval of the Mortgage Loan application, by a Qualified Appraiser.

            (xxiv) In the event the Mortgage constitutes a deed of trust, a
      trustee, duly qualified under applicable law to serve as such, has been
      properly designated and currently so serves, and no fees or expenses are
      or will become payable by the Trustee to the trustee under the deed of
      trust, except in connection with a trustee's sale after default by the
      Mortgagor.

            (xxv) No Mortgage Loan is a graduated payment mortgage loan, no
      Mortgage Loan has a shared appreciation or other contingent interest
      feature, and no Mortgage Loan contains any "buy-down" feature.

            (xxvi) The Mortgagor has received all disclosure materials required
      by applicable law with respect to the making of mortgage loans of the same
      type as the Mortgage Loan and rescission materials required by applicable
      law if the Mortgage Loan is a Refinance Mortgage Loan.

            (xxvii) Each Primary Insurance Policy to which any Mortgage Loan is
      subject will be issued by an insurer acceptable to Fannie Mae or Freddie
      Mac, which insures that portion of the Mortgage Loan in excess of the
      portion of the Appraised Value of the Mortgaged Property required by
      Fannie Mae. All provisions of such Primary Insurance Policy have been and
      are being complied with, such policy is in full force and effect, and all
      premiums due thereunder have been paid. Any Mortgage subject to any such
      Primary Insurance Policy obligates the Mortgagor thereunder to maintain
      such insurance and to pay all premiums and charges in connection therewith
      at least until Loan-to-Value Ratio of such Mortgage Loan is reduced to
      less than 80%. The Mortgage Interest Rate for the Mortgage Loan does not
      include any such insurance premium.

            (xxviii) To the best of the Depositor's knowledge as of the date of
      origination of the Mortgage Loan, (A) the Mortgaged Property is lawfully
      occupied under applicable law, (B) all inspections, licenses and
      certificates required to be made or issued with respect to all occupied
      portions of the Mortgaged Property and, with respect to the use and
      occupancy of the same, including but not limited to certificates of
      occupancy, have been made or obtained from the appropriate authorities and
      (C) no improvement located on or part of the Mortgaged Property is in
      violation of any zoning law or regulation.

            (xxix) The Assignment of Mortgage (except with respect to any
       Mortgage that has been recorded in the name of MERS or its designee) is in
      recordable form and is acceptable for recording under the laws of the
      jurisdiction in which the Mortgaged Property is located.

            (xxx) All payments required to be made prior to the Cut-off Date for
      such Mortgage Loan under the terms of the Mortgage Note have been made and
      no more than 0.20% (by Cut-off Date Principal Balance) of the Mortgage
      Loan have been more than 30 days delinquent more than once in the twelve
      month period immediately prior to the Cut-off Date.

            (xxxi) With respect to each Mortgage Loan, the Depositor or Servicer
      is in possession of a complete Mortgage File except for the documents
      which have been delivered to the Trustee or which have been submitted for
      recording and not yet returned.

            (xxxii) 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.

            (xxxiii) Any future advances made prior to the Cut-off Date have
      been consolidated with the outstanding principal amount secured by the
      Mortgage, and the secured principal amount, as consolidated, bears a
      single interest rate and single repayment term. The lien of the Mortgage
      securing the consolidated principal amount is expressly insured as having
      first lien priority by a title insurance policy, an endorsement to the
      policy insuring the mortgagee's consolidated interest or by other title
      evidence acceptable to Fannie Mae and Freddie Mac. The consolidated
      principal amount does not exceed the original principal amount of the
      Mortgage Loan.

            (xxxiv) The Mortgage Loan was underwritten in accordance with the
      applicable Underwriting Guidelines in effect at the time of origination
      with exceptions thereto exercised in a reasonable manner.

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

             (xxxvi) No more than 0.25% (by Cut-off Date Principal Balance) of
      the Mortgage Loans are secured by long-term residential leases.

            (xxxvii) The Mortgaged Property is located in the state identified
      in the Mortgage Loan Schedule and consists of a parcel of real property
      with a detached single family residence erected thereon, or a two- to
      four-family dwelling, or an individual condominium unit, or an individual
      unit in a planned unit development, or, in the case of Mortgage Loans
      secured by Co-op Shares, leases or occupancy agreements; provided,
      however, that any condominium project or planned unit development
      generally conforms with the applicable Underwriting Guidelines regarding
      such dwellings, and no residence or dwelling is a mobile home or a
      manufactured dwelling.

            (xxxviii) The Depositor used no adverse selection procedures in
      selecting the Mortgage Loan for inclusion in the Trust Estate.

            (xxxix) Each Mortgage Loan is a "qualified mortgage" within the
      meaning of Section 860G(a)(3) of the Code.

            (xl) With respect to each Mortgage where a lost note affidavit has
      been delivered to the Trustee in place of the related Mortgage Note, the
      related Mortgage Note is no longer in existence.

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

             (xlii) No Mortgage Loan is a High Cost Loan or Covered Loan, as
      applicable (as such terms are defined in the then-current S&P's LEVELS(R)
      Glossary which is now Version 5.7, Appendix E) and no Mortgage Loan
      originated on or after October 1, 2002 through March 6, 2003 is governed
      by the Georgia Fair Lending Act.

            (xliii) No Mortgage Loan is subject to the provisions of the Home
      Ownership and Equity Protection Act of 1994, as amended.

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

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

             Upon discovery by any of the Depositor, the Servicer, the Trustee or
the Custodian that any of the representations and warranties set forth in this
Section 2.04 is not accurate (referred to herein as a "breach") and that such
breach materially and adversely affects the interests of the Certificateholders
in the related Mortgage Loan, the party discovering such breach shall give
prompt written notice to the other parties (any Custodian being so obligated
under a custodial agreement); provided that any such breach that causes the
Mortgage Loan not to be a "qualified mortgage" within the meaning of Section
860G(a)(3) of the Code shall be deemed to materially and adversely affect the
interests of the Certificateholders. Within 90 days of its discovery or its
receipt of notice of any such breach, the 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
Repurchase Price or (ii) if within two years of the Closing Date, substitute for
such Mortgage Loan in the manner described in Section 2.02; provided that if the
breach would cause the Mortgage Loan to be other than a "qualified mortgage" as
defined in Section 860G(a)(3) of the Code, any such repurchase or substitution
must occur within 90 days from the date the breach was discovered. In addition
to the foregoing, if a breach of the representation set forth in clause (vi) or
(xlii) of this Section 2.04 occurs as a result of a violation of an applicable
predatory or abusive lending law, the Depositor shall reimburse the Trust for
all costs or damages incurred by the Trust as a result of the violation of such
law (such amount, the "Reimbursement Amount"). The Repurchase Price of any
repurchase described in this paragraph, the Substitution Adjustment Amount, if
any, and any Reimbursement Amount shall be deposited in the 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 Trustee
acknowledges the issuance of the uncertificated REMIC 1 Regular Interests and
declares that it holds such regular interests as assets of REMIC 2. The Trustee
acknowledges the obligation of the Class CE Certificates to pay Cap Carryover
Amounts, and declares that it shall hold the same as assets of the Grantor Trust
on behalf of the Holders of the Class A-1, Class A-2, Class A-3, Class A-4,
Class A-5, Class A-6, Class M-1, Class M-2, Class M-3, Class M-4 and Class M-5
Certificates, which shall be treated as beneficially owning the right to receive
the Cap Carryover Amounts from the Grantor Trust. In addition to the assets
described in the preceding sentence, the assets of the Grantor Trust shall also
include the Cap Carryover Reserve Account and the beneficial interest of the
Class CE Certificates with respect thereto, subject to the obligation to pay Cap
Carryover Amounts. The interests evidenced by the Certificates constitute the
entire beneficial ownership interest in the Trust.

            Section 2.06 Designation of Start-up Day. The Closing Date is hereby
designated as the "start-up day" of each of the REMICs 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 REMIC is October 25,
2036.

                                   ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

             Section 3.01 Servicer to Service Mortgage Loans. For and on behalf
of the Certificateholders, the Servicer shall service and administer the
Mortgage Loans, all in accordance with the terms of this Agreement, Customary
Servicing Procedures, applicable law and the terms of the Mortgage Notes and
Mortgages. In connection with such servicing and administration, the Servicer
shall have full power and authority, acting alone and/or through Subservicers as
provided in Section 3.02, to do or cause to be done any and all things that it
may deem necessary or desirable in connection with such servicing and
administration including, but not limited to, the power and authority, subject
to the terms hereof, (a) to execute and deliver, on behalf of the
Certificateholders and the Trustee, customary consents or waivers and other
instruments and documents, (b) to consent, with respect to the Mortgage Loans it
services, to transfers of any Mortgaged Property and assumptions of the Mortgage
Notes and related Mortgages (but only in the manner provided in this Agreement),
(c) to collect any Insurance Proceeds and other Liquidation Proceeds relating to
the Mortgage Loans it services, and (d) to effectuate foreclosure or other
conversion of the ownership of the Mortgaged Property securing any Mortgage Loan
it services. The Servicer shall represent and protect the interests of the Trust
in the same manner as it protects its own interests in mortgage loans in its own
portfolio in any claim, proceeding or litigation regarding a Mortgage Loan and
shall not make or permit any modification, waiver or amendment of any term of
any Mortgage Loan, except as provided pursuant to Section 3.21. Without limiting
the generality of the foregoing, the Servicer, in its own name or in the name of
any Subservicer or the Depositor and the Trustee, is hereby authorized and
empowered by the Depositor and the Trustee, when the Servicer or any
Subservicer, as the case may be, believes it appropriate in its reasonable
judgment, to execute and deliver, on behalf of the Trustee, the Depositor, the
Certificateholders or any of them, any and all instruments or agreements of
satisfaction, cancellation, default, assumption, modification, discharge,
partial or full release, and all other comparable instruments and agreements,
with respect to the Mortgage Loans it services, and with respect to the related
Mortgaged Properties held for the benefit of the Certificateholders. To the
extent that the Servicer is not permitted to execute and deliver such documents
pursuant to the preceding sentence, the Servicer shall prepare and deliver to
the Depositor and/or the Trustee such documents requiring execution and delivery
by either or both of them as are necessary or appropriate to enable the Servicer
to service and administer the Mortgage Loans it services. Upon receipt of such
documents, the Depositor and/or the Trustee, upon the direction of the Servicer,
shall promptly execute such documents and deliver them to the Servicer.
Alternatively, upon the request of the Servicer, the Trustee shall execute and
deliver to the Servicer any additional powers of attorney and other documents
prepared by the Servicer that are reasonably necessary or appropriate to enable
the Servicer to carry out its servicing and administrative duties under this
Agreement.

            In accordance with the standards of the preceding paragraph, the
Servicer shall advance or cause to be advanced funds as necessary for the
purpose of effecting the payment of taxes and assessments on the Mortgaged
Properties relating to the Mortgage Loans it services, which Servicing Advances
shall be reimbursable in the first instance from related collections from the
Mortgagors pursuant to Section 3.09, and further as provided in Section 3.11.
The costs incurred by the Servicer, if any, in effecting the timely payments of
taxes and assessments on the Mortgaged Properties and related insurance premiums
shall not, for the purpose of calculating monthly distributions to the
Certificateholders, be added to the Stated Principal Balances of the related
Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so permit.

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

            Section 3.02 Subservicing; Enforcement of the Obligations of
Servicer. (a) The Servicer may arrange for the subservicing of any Mortgage Loan
it services by a Subservicer pursuant to a Subservicing Agreement; provided,
however, that such subservicing arrangement and the terms of the related
Subservicing Agreement must provide for the servicing of such Mortgage Loan in a
manner consistent with the servicing arrangements contemplated hereunder.
Notwithstanding the provisions of any Subservicing Agreement, any of the
provisions of this Agreement relating to agreements or arrangements between the
Servicer and a Subservicer or reference to actions taken through a Subservicer
or otherwise, the Servicer shall remain obligated and liable to the Depositor,
the Trustee and the Certificateholders for the servicing and administration of
the Mortgage Loans it services in accordance with the provisions of this
Agreement without diminution of such obligation or liability by virtue of such
Subservicing Agreements or arrangements or by virtue of indemnification from the
Subservicer and to the same extent and under the same terms and conditions as if
the Servicer alone were servicing and administering those Mortgage Loans. All
actions of each Subservicer performed pursuant to the related Subservicing
Agreement shall be performed as agent of the Servicer with the same force and
effect as if performed directly by the Servicer.

            (b) For purposes of this Agreement, the Servicer shall be deemed to
   have received any collections, recoveries or payments with respect to the
   Mortgage Loans it services that are received by a Subservicer regardless of
   whether such payments are remitted by the Subservicer to the Servicer.

            (c) As part of its servicing activities hereunder, the Servicer, for
   the benefit of the Trustee and the Certificateholders, shall use its best
   reasonable efforts to enforce the obligations of each Subservicer engaged by
   the Servicer under the related Subservicing Agreement, to the extent that the
   non-performance of any such obligation would have a material and adverse
   effect on a Mortgage Loan. Such enforcement, including, without limitation,
   the legal prosecution of claims, termination of Subservicing Agreements and
   the pursuit of other appropriate remedies, shall be in such form and carried
   out to such an extent and at such time as the Servicer, in its good faith
   business judgment, would require were it the owner of the related Mortgage
   Loans. The Servicer shall pay the costs of such enforcement at its own
   expense, and shall be reimbursed therefor only (i) from a general recovery
   resulting from such enforcement to the extent, if any, that such recovery
   exceeds all amounts due in respect of the related Mortgage Loan or (ii) from
   a specific recovery of costs, expenses or attorneys fees against the party
   against whom such enforcement is directed.

            (d) Any Subservicing Agreement entered into by the Servicer shall
   provide that it may be assumed or terminated by the Trustee, if the Trustee
   has assumed the duties of the Servicer, or any successor Servicer, at the
   Trustee's or successor Servicer's option, as applicable, without cost or
   obligation to the assuming or terminating party or the Trust Estate, upon the
   assumption by such party of the obligations of the Servicer pursuant to
   Section 8.05.

            (e) Notwithstanding the foregoing, to the extent the Servicer
   engages any affiliate or third party vendor, including any Subservicer, in
   connection with the performance of any of its duties under this Agreement,
   the Servicer shall immediately notify the Depositor in writing of such
   engagement. To the extent the Depositor notifies the Servicer and the Trustee
   that it has determined that any such affiliate, third party vendor or
   Subservicer is a Servicing Function Participant, the Servicer shall cause
   such Servicing Function Participant to prepare a separate assessment and
   attestation report, as contemplated by Section 3.19 of this Agreement and
   deliver such report to the Trustee as set forth in Section 3.22 of this
   Agreement. In addition, to the extent the Depositor notifies the Servicer and
   the Trustee that it has determined that any such Servicing Function
   Participant would be a "servicer" within the meaning of Item 1101 of
   Regulation AB and meets the criteria in Item 1108(a)(2)(i), (ii) or (iii) of
   Regulation AB (an "Additional Servicer"), the Servicer shall cause such
   Additional Servicer to prepare a separate compliance statement as
   contemplated by Section 3.18 of this Agreement and deliver such statement to
   the Trustee as set forth in Section 3.22 of this Agreement. In addition, if
   the Depositor determines any such Servicing Function Participant would be a
   "servicer" within the meaning of Item 1101 of Regulation AB, the Servicer
   shall cause such Servicing Function Participant to provide the Depositor and
   the Trustee the information required by Section 1108(b) and 1108(c) of
   Regulation AB within two Business Days following such engagement. To the
   extent the Servicer terminates any such Servicing Function Participant that
   the Depositor has determined is a "servicer" within the meaning of Item 1101
   of Regulation AB, the Servicer shall provide the Depositor and the Trustee
   the information required to enable the Trustee to accurately and timely
   report such event under Item 6.02 of Form 8-K (if the Trust's Exchange Act
   reporting requirements have not been suspended pursuant to Section 15(d) of
   the Exchange Act as set forth in 3.22(g)).

            Section 3.03 Fidelity Bond; Errors and Omissions Insurance. The
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 acting in any capacity requiring such persons to
handle funds, money, documents or papers relating to the Mortgage Loans it
services. These policies must insure the Servicer against losses resulting from
dishonest or fraudulent acts committed by the Servicer's personnel, any
employees of outside firms that provide data processing services for the
Servicer, and temporary contract employees or student interns. Such fidelity
bond shall also protect and insure the Servicer against losses in connection
with the release or satisfaction of a Mortgage Loan without having obtained
payment in full of the indebtedness secured thereby. No provision of this
Section 3.03 requiring such fidelity bond and errors and omissions insurance
shall diminish or relieve the 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 Servicer by express waiver of Fannie Mae or
Freddie Mac.

            Section 3.04 Access to Certain Documentation. The Servicer shall
provide 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 upon reasonable and prior written request and during normal business
hours at the offices designated by the Servicer; provided that the Servicer
shall be entitled to be reimbursed by each such Certificateholder for actual
expenses incurred by the Servicer in providing such reports and access. Nothing
in this Section 3.04 shall limit the obligation of the Servicer to observe any
applicable law and the failure of 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 Insurance Policy; Claims;
Collections of BPP Mortgage Loan Payments. (a) With respect to each Mortgage
Loan with a Loan-to-Value Ratio in excess of 80% or such other Loan-to-Value
Ratio as may be required by law that was originated with a Primary Insurance
Policy, the Servicer shall, without any cost to the Trust Estate, maintain or
cause the Mortgagor to maintain in full force and effect a Primary Insurance
Policy insuring that portion of the Mortgage Loan in excess of a percentage in
conformity with Fannie Mae requirements. The Servicer shall pay or shall cause
the Mortgagor to pay the premium thereon on a timely basis, at least until the
Loan-to-Value Ratio of such Mortgage Loan is reduced to 80% or such other
Loan-to-Value Ratio as may be required by law. If such Primary Insurance Policy
is terminated, the Servicer shall obtain from another insurer a comparable
replacement policy, with a total coverage equal to the remaining coverage of
such terminated Primary Insurance Policy. If the insurer shall cease to be an
insurer acceptable to Fannie Mae or Freddie Mac, the Servicer shall notify the
Trustee in writing, it being understood that the Servicer shall not have any
responsibility or liability for any failure to recover under the Primary
Insurance Policy for such reason. If the Servicer determines that recoveries
under the Primary Insurance Policy are jeopardized by the financial condition of
the insurer, the Servicer shall obtain from another insurer which meets the
requirements of this Section 3.05 a replacement insurance policy. The Servicer
shall not take any action that would result in noncoverage under any applicable
Primary Insurance Policy of any loss that, but for the actions of the Servicer,
would have been covered thereunder. In connection with any assumption or
substitution agreement entered into or to be entered into pursuant to Section
3.13, the Servicer shall promptly notify the insurer under the related Primary
Insurance Policy, if any, of such assumption or substitution of liability in
accordance with the terms of such Primary Insurance Policy and shall take all
actions which may be required by such insurer as a condition to the continuation
of coverage under such Primary Insurance Policy. If such Primary Insurance
Policy is terminated as a result of such assumption or substitution of
liability, the Servicer shall obtain a replacement Primary Insurance Policy as
provided above.

            In connection with its activities as servicer, the Servicer agrees
to prepare and present, on behalf of itself, the Trustee and the
Certificateholders, claims to the insurer under any Primary Insurance Policy in
a timely fashion in accordance with the terms of such Primary Insurance Policy
and, in this regard, to take such action as shall be necessary to permit
recovery under any Primary Insurance Policy respecting a defaulted Mortgage
Loan. Pursuant to Section 3.09(a), any amounts collected by the Servicer under
any Primary Insurance Policy shall be deposited in the related Escrow Account,
subject to withdrawal pursuant to Section 3.09(b).

            The Servicer will comply with all provisions of applicable state and
federal law relating to the cancellation of, or collection of premiums with
respect to, Primary Mortgage Insurance, including, but not limited to, the
provisions of the Homeowners Protection Act of 1998, and all regulations
promulgated thereunder, as amended from time to time.

            (b) The Servicer shall take all actions necessary to collect, on
   behalf of the Trust, any BPP Mortgage Loan Payments required to be made to
   the Trust pursuant to the Mortgage Loan Purchase Agreement.

            Section 3.06 Rights of the Depositor and the Trustee in Respect of
the Servicer. The Depositor may, but is not obligated to, enforce the
obligations of the Servicer hereunder and may, but is not obligated to, perform,
or cause a designee to perform, any defaulted obligation of the Servicer
hereunder and in connection with any such defaulted obligation to exercise the
related rights of the Servicer hereunder; provided that the Servicer shall not
be relieved of any of its obligations hereunder by virtue of such performance by
the Depositor or its designee. Neither the Trustee nor the Depositor shall have
any responsibility or liability for any action or failure to act by the Servicer
nor shall the Trustee or the Depositor be obligated to supervise the performance
of the Servicer hereunder or otherwise.

            Any Subservicing Agreement that may be entered into and any
transactions or services relating to the Mortgage Loans involving a Subservicer
in its capacity as such shall be deemed to be between the Subservicer and the
Servicer alone, and the Trustee and Certificateholders shall not be deemed
parties thereto and shall have no claims, rights, obligations, duties or
liabilities with respect to the Subservicer except as set forth in Section 3.07.
The Servicer shall be solely liable for all fees owed by it to any Subservicer,
irrespective of whether the Servicer's compensation pursuant to this Agreement
is sufficient to pay such fees.

            Section 3.07 Trustee to Act as Servicer. If the Servicer shall for
any reason no longer be the Servicer hereunder (including by reason of an Event
of Default), the Trustee shall within 90 days of such time, assume, if it so
elects, or shall appoint a successor Servicer to assume, all of the rights and
obligations of the Servicer hereunder arising thereafter (except that the
Trustee shall not be (a) liable for losses of the Servicer pursuant to Section
3.12 or any acts or omissions of the predecessor Servicer hereunder, (b)
obligated to make Advances if it is prohibited from doing so by applicable law
or (c) deemed to have made any representations and warranties of the Servicer
hereunder). Any such assumption shall be subject to Sections 7.02 and 8.05. If
the Servicer shall for any reason no longer be the Servicer (including by reason
of any Event of Default), the Trustee or the successor Servicer may elect to
succeed to any rights and obligations of the Servicer under each Subservicing
Agreement or may terminate each Subservicing Agreement. If it has elected to
assume the Subservicing Agreement, the Trustee or the successor Servicer shall
be deemed to have assumed all of the Servicer's interest therein and to have
replaced the Servicer as a party to any Subservicing Agreement entered into by
the Servicer as contemplated by Section 3.02 to the same extent as if the
Subservicing Agreement had been assigned to the assuming party except that the
Servicer shall not be relieved of any liability or obligations under any such
Subservicing Agreement.

            The Servicer that is no longer the Servicer hereunder shall, upon
request of the Trustee, but at the expense of such predecessor Servicer, deliver
to the assuming party all documents and records relating to each Subservicing
Agreement or substitute servicing agreement and the Mortgage Loans then being
serviced thereunder and an accounting of amounts collected or held by it and
otherwise use its best efforts to effect the orderly and efficient transfer of
such substitute Subservicing Agreement to the assuming party. The Trustee shall
be entitled to be reimbursed from the predecessor Servicer (or the Trust if the
predecessor Servicer is unable to fulfill its obligations hereunder) for all
Servicing Transfer Costs.

            Section 3.08 Collection of Mortgage Loan Payments; Servicer
Custodial Account; Certificate Account;. (a) Continuously from the date hereof
until the principal and interest on all Mortgage Loans are paid in full, the
Servicer will proceed diligently, in accordance with this Agreement, to collect
all payments due under each of the Mortgage Loans it services when the same
shall become due and payable. Further, the Servicer will in accordance with all
applicable law and Customary Servicing Procedures ascertain and estimate taxes,
assessments, fire and hazard insurance premiums, mortgage insurance premiums and
all other charges with respect to the Mortgage Loans it services that, as
provided in any Mortgage, will become due and payable to the end that the
installments payable by the Mortgagors will be sufficient to pay such charges as
and when they become due and payable. Consistent with the foregoing, the
Servicer may in its discretion (i) waive any late payment charge or any
prepayment charge or penalty interest in connection with the prepayment of a
Mortgage Loan it services and (ii) extend the due dates for payments due on a
Mortgage Note for a period not greater than 120 days; provided, however, that
the Servicer cannot extend the maturity of any such Mortgage Loan past the date
on which the final payment is due on the latest maturing Mortgage Loan as of the
Cut-off Date. In the event of any such arrangement, the Servicer shall make
Periodic Advances on the related Mortgage Loan in accordance with the provisions
of Section 3.20 during the scheduled period in accordance with the amortization
schedule of such Mortgage Loan without modification thereof by reason of such
arrangements. The Servicer shall not be required to institute or join in
litigation with respect to collection of any payment (whether under a Mortgage,
Mortgage Note or otherwise or against any public or governmental authority with
respect to a taking or condemnation) if it reasonably believes that enforcing
the provision of the Mortgage or other instrument pursuant to which such payment
is required is prohibited by applicable law.

            (b) The Servicer shall establish and maintain the Servicer Custodial
   Account. The Servicer shall deposit or cause to be deposited into the
   Servicer Custodial Account, all on a daily basis within one Business Day of
   receipt, except as otherwise specifically provided herein, the following
   payments and collections remitted by Subservicers or received by the 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 with respect to the Mortgage Loans it services:

            (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 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 3.09(a), and other than any Excess
      Proceeds and (B) any Insurance Proceeds released from an Escrow Account
      pursuant to Section 3.09(b)(iv);

             (iv) any amount required to be deposited by the Servicer pursuant to
      Section 3.08(d) in connection with any losses on Permitted Investments
      with respect to the Servicer Custodial Account;

            (v) any amounts required to be deposited by the Servicer pursuant to
      Section 3.14;

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

            (vii) Periodic Advances made by the Servicer pursuant to Section
      3.20 and any Compensating Interest;

            (viii) any Recoveries; and

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

            The foregoing requirements for deposits to the Servicer Custodial
Account by the Servicer shall be exclusive it being understood and agreed that,
without limiting the generality of the foregoing, Ancillary Income need not be
deposited by the Servicer. If the Servicer shall deposit in the Servicer
Custodial Account any amount not required to be deposited, it may at any time
withdraw or direct the institution maintaining the Servicer Custodial Account to
withdraw such amount from the Servicer Custodial Account, any provision herein
to the contrary notwithstanding. The Servicer Custodial Account may contain
funds that belong to one or more trust funds created for mortgage pass-through
certificates of other series and may contain other funds respecting payments on
mortgage loans belonging to the Servicer or serviced by the Servicer on behalf
of others. Notwithstanding such commingling of funds, the Servicer shall keep
records that accurately reflect the funds on deposit in the Servicer Custodial
Account that have been identified by it as being attributable to the Mortgage
Loans it services. The Servicer shall maintain adequate records with respect to
all withdrawals made pursuant to this Section 3.08. All funds required to be
deposited in the Servicer Custodial Account shall be held in trust for the
Certificateholders until withdrawn in accordance with Section 3.11.

            (c) The Trustee shall establish and maintain, on behalf of the
   Certificateholders, the Certificate Account. The Trustee shall, promptly upon
   receipt, deposit in the Certificate Account and retain therein the following:

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

            (ii) any amount paid by the Trustee pursuant to Section 3.08(d) in
      connection with any losses on Permitted Investments with respect to the
      Certificate Account; and

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

            If the Servicer shall remit any amount not required to be remitted,
it may at any time direct the Trustee 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
Trustee which describes the amounts deposited in error in the Certificate
Account. All funds required to be deposited in the Certificate Account shall be
held by the Trustee in trust for the Certificateholders until disbursed in
accordance with this Agreement or withdrawn in accordance with Section 3.11. In
no event shall the Trustee incur liability for withdrawals from the Certificate
Account at the direction of the Servicer.

            (d) Each institution at which the Servicer Custodial Account or the
   Certificate Account is maintained shall invest the funds therein as directed
   in writing by the Servicer, in the case of the Servicer Custodial Account, or
   the Trustee, in the case of the Certificate Account, in Permitted
   Investments, which shall mature not later than (i) in the case of the
   Servicer Custodial Account, the Business Day next preceding the related
   Remittance 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 Remittance Date) and (ii) in the case of the
   Certificate Account, 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 Servicer Custodial Account Reinvestment Income shall be for the benefit
   of the Servicer as part of its Servicing Compensation and shall be retained
   by it monthly as provided herein. All income or gain (net of any losses)
   realized from any such investment of funds on deposit in the Certificate
   Account shall be for the benefit of the Trustee as additional compensation
   and shall be retained by it monthly as provided herein. The amount of any
   losses realized in the Servicer Custodial Account or the Certificate Account
   incurred in any such account in respect of any such investments shall
   promptly be deposited by the Servicer in the Servicer Custodial Account or by
   the Trustee in the Certificate Account, as applicable.

            (e) The Servicer shall give notice to the Trustee of any proposed
   change of the location of the Servicer Custodial Account maintained by the
   Servicer not later than 30 days and not more than 45 days prior to any change
   thereof. The Trustee shall give notice to the Servicer, each Rating Agency
   and the Depositor of any proposed change of the location of the Certificate
   Account not later than 30 days after and not more than 45 days prior to any
   change thereof. The creation of the Servicer Custodial Account shall be
   evidenced by a certification substantially in the form of Exhibit F hereto. A
   copy of such certification shall be furnished to the Trustee.

             Section 3.09 Collection of Taxes, Assessments and Similar Items;
Escrow Accounts. (a) To the extent required by the related Mortgage Note and not
violative of current law, the Servicer shall segregate and hold all funds
collected and received pursuant to each Mortgage Loan which constitute Escrow
Payments in trust separate and apart from any of its own funds and general
assets and for such purpose shall establish and maintain one or more escrow
accounts (collectively, the "Escrow Account"), titled "Bank of America, National
Association, in trust for registered holders of Banc of America Alternative Loan
Trust 2006-7 Mortgage Pass-Through Certificates, Series 2006-7 and various
Mortgagors." The Escrow Account shall be established with a commercial bank, a
savings bank or a savings and loan association that meets the guidelines set
forth by Fannie Mae or Freddie Mac as an eligible institution for escrow
accounts and which is a member of the Automated Clearing House. In any case, the
Escrow Account shall be insured by the FDIC to the fullest extent permitted by
law. The Servicer shall deposit in the appropriate Escrow Account on a daily
basis, and retain therein: (i) all Escrow Payments collected on account of the
Mortgage Loans, (ii) all amounts representing proceeds of any hazard insurance
policy which are to be applied to the restoration or repair of any related
Mortgaged Property and (iii) all amounts representing proceeds of any Primary
Insurance Policy. Nothing herein shall require the Servicer to compel a
Mortgagor to establish an Escrow Account in violation of applicable law.

            (b) Withdrawals of amounts so collected from the Escrow Accounts may
   be made by the Servicer only (i) to effect timely payment of taxes,
   assessments, mortgage insurance premiums, fire and hazard insurance premiums,
   condominium or PUD association dues, or comparable items constituting Escrow
   Payments for the related Mortgage, (ii) to reimburse the Servicer out of
   related Escrow Payments made with respect to a Mortgage Loan for any
   Servicing Advance made by the Servicer pursuant to Section 3.09(c) with
   respect to such Mortgage Loan, (iii) to refund to any Mortgagor any sums
   determined to be overages, (iv) for transfer to the Servicer Custodial
   Account upon default of a Mortgagor or in accordance with the terms of the
   related Mortgage Loan and if permitted by applicable law, (v) for application
   to restore or repair the Mortgaged Property, (vi) to pay to the Mortgagor, to
   the extent required by law, any interest paid on the funds deposited in the
   Escrow Account, (vii) to pay to itself any interest earned on funds deposited
   in the Escrow Account (and not required to be paid to the Mortgagor), (viii)
   to the extent permitted under the terms of the related Mortgage Note and
   applicable law, to pay late fees with respect to any Monthly Payment which is
   received after the applicable grace period, (ix) to withdraw suspense
   payments that are deposited into the Escrow Account, (x) to withdraw any
   amounts inadvertently deposited in the Escrow Account or (xi) to clear and
   terminate the Escrow Account upon the termination of this Agreement in
   accordance with Section 10.01. Any Escrow Account shall not be a part of the
   Trust Estate.

            (c) With respect to each Mortgage Loan, the Servicer shall maintain
   accurate records reflecting the status of taxes, assessments and other
   charges which are or may become a lien upon the Mortgaged Property and the
   status of Primary Insurance Policy premiums and fire and hazard insurance
   coverage. The Servicer shall obtain, from time to time, all bills for the
   payment of such charges (including renewal premiums) and shall effect payment
   thereof prior to the applicable penalty or termination date and at a time
   appropriate for securing maximum discounts allowable, employing for such
   purpose deposits of the Mortgagor in the Escrow Account, if any, which shall
   have been estimated and accumulated by the Servicer in amounts sufficient for
   such purposes, as allowed under the terms of the Mortgage. To the extent that
   a Mortgage does not provide for Escrow Payments, the Servicer shall determine
   that any such payments are made by the Mortgagor. The Servicer assumes full
   responsibility for the timely payment of all such bills and shall effect
   timely payments of all such bills irrespective of each Mortgagor's faithful
   performance in the payment of same or the making of the Escrow Payments. The
   Servicer shall advance any such payments that are not timely paid, but the
   Servicer shall be required so to advance only to the extent that such
   Servicing Advances, in the good faith judgment of the Servicer, will be
   recoverable by the Servicer out of Insurance Proceeds, Liquidation Proceeds
   or otherwise.

            Section 3.10 Access to Certain Documentation and Information
Regarding the Mortgage Loans. The Servicer shall afford 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 Servicer.

             Section 3.11 Permitted Withdrawals from the Servicer Custodial
Account and Certificate Account. (a) The Servicer may from time to time make
withdrawals from the Servicer Custodial Account, for the following purposes:

            (i) to pay to the Servicer (to the extent not previously retained),
      the Servicing Compensation to which it is entitled pursuant to Section
      3.17;

            (ii) to reimburse the Servicer for unreimbursed Advances made by it,
      such right of reimbursement pursuant to this clause (ii) being limited to
      amounts received on the Mortgage Loan(s) (including amounts received in
      respect of BPP Mortgage Loan Payments for such Mortgage Loan) in respect
      of which any such Advance was made;

             (iii) to reimburse the Servicer for any Nonrecoverable Advance
      previously made;

            (iv) to reimburse the Servicer for Insured Expenses from the related
      Insurance Proceeds;

            (v) 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;

            (vi) to reimburse the Servicer or the Depositor for expenses
      incurred by any of them and reimbursable pursuant to Section 7.03;

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

            (viii) on or prior to the Remittance Date, to withdraw an amount
      equal to the related Interest Remittance Amount and Principal Remittance
      Amount for such Distribution Date, to the extent on deposit, and remit
      such amount in immediately available funds to the Trustee for deposit in
      the Certificate Account; and

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

            The Servicer shall keep and maintain separate accounting, on a
Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Servicer Custodial Account pursuant to clauses (i), (ii),
(iv) and (v). Prior to making any withdrawal from the Servicer Custodial Account
pursuant to clause (iii), the Servicer shall deliver to the Trustee an Officer's
Certificate of a Servicing Officer indicating the amount of any previous Advance
determined by the Servicer to be a Nonrecoverable Advance and identifying the
related Mortgage Loan(s) and their respective portions of such Nonrecoverable
Advance. The Servicer shall notify the Depositor and the Trustee of the amount,
purpose and party paid pursuant to clause (vi) above.

            (b) The Trustee shall be deemed to withdraw funds from the
Certificate Account for distributions to Certificateholders in the manner
specified in this Agreement. In addition, the Trustee may from time to time make
withdrawals from the Certificate Account for the following purposes:

            (i) to pay to itself the Trustee Fee, to the extent not paid under
      Section 5.02(a);

            (ii) to pay to itself as additional compensation earnings on or
      investment income with respect to funds in the Certificate Account and any
      other amounts (other than the Trustee Fee) due to it under this Agreement
      for the related Distribution Date;

            (iii) to withdraw and return to the Servicer any amount deposited in
      the Certificate Account and not required to be deposited therein; and

            (iv) to clear and terminate the Certificate Account upon termination
      of this Agreement pursuant to Section 10.01.

            The Trustee shall notify the Depositor and the Servicer of the
amount and purpose of any payments made pursuant to clause (ii) above (other
than any earnings or investment income with respect to funds in the Certificate
Account).

            Section 3.12 Maintenance of Hazard Insurance. The Servicer shall
cause to be maintained for each Mortgage Loan, fire and hazard insurance with
extended coverage customary in the area where the Mortgaged Property is located
in an amount which is at least equal to the lesser of (a) the full insurable
value of the Mortgaged Property or (b) the greater of (i) the outstanding
principal balance owing on the Mortgage Loan and (ii) an amount such that the
proceeds of such insurance shall be sufficient to avoid the application to the
Mortgagor or loss payee of any coinsurance clause under the policy. If the
Mortgaged Property is in an area identified in the Federal Register by the
Federal Emergency Management Agency as having special flood hazards (and such
flood insurance has been made available) the Servicer will cause to be
maintained a flood insurance policy meeting the requirements of the current
guidelines of the Federal Insurance Administration and the requirements of
Fannie Mae or Freddie Mac. The Servicer shall also maintain on REO Property,
fire and hazard insurance with extended coverage in an amount which is at least
equal to the maximum insurable value of the improvements which are a part of
such property, liability insurance and, to the extent required, flood insurance
in an amount required above. Any amounts collected by the Servicer under any
such policies (other than amounts to be deposited in an Escrow Account and
applied to the restoration or repair of the property subject to the related
Mortgage or property acquired in liquidation of the Mortgage Loan, or to be
released to the Mortgagor in accordance with Customary Servicing Procedures)
shall be deposited in the Servicer Custodial Account, subject to withdrawal
pursuant to Section 3.11(a). It is understood and agreed that no earthquake or
other additional insurance need be required by the Servicer of any Mortgagor or
maintained on REO Property, other than pursuant to such applicable laws and
regulations as shall at any time be in force and as shall require such
additional insurance. All policies required hereunder shall be endorsed with
standard mortgagee clauses with loss payable to the Servicer, and shall provide
for at least 30 days' prior written notice of any cancellation, reduction in
amount or material change in coverage to the Servicer.

            The hazard insurance policies for each Mortgage Loan secured by a
unit in a condominium development or planned unit development shall be
maintained with respect to such Mortgage Loan and the related development in a
manner which is consistent with Fannie Mae requirements.

            Notwithstanding the foregoing, the Servicer may maintain a blanket
policy insuring against hazard losses on all of the Mortgaged Properties
relating to the Mortgage Loans in lieu of maintaining the required hazard
insurance policies for each Mortgage Loan and may maintain a blanket policy
insuring against special flood hazards in lieu of maintaining any required flood
insurance. Any such blanket policies shall (A) be consistent with prudent
industry standards, (B) name the Servicer as loss payee, (C) provide coverage in
an amount equal to the aggregate unpaid principal balance on the related
Mortgage Loans without co-insurance, and (D) otherwise comply with the
requirements of this Section 3.12. Any such blanket policy may contain a
deductible clause; provided that if any Mortgaged Property is not covered by a
separate policy otherwise complying with this Section 3.12 and a loss occurs
with respect to such Mortgaged Property which loss would have been covered by
such a policy, the Servicer shall deposit in the Servicer Custodial Account the
difference, if any, between the amount that would have been payable under a
separate policy complying with this Section 3.12 and the amount paid under such
blanket policy.

            Section 3.13 Enforcement of Due-On-Sale Clauses; Assumption
Agreements. (a) Except as otherwise provided in this Section 3.13, when any
Mortgaged Property subject to a Mortgage has been conveyed by the Mortgagor, the
Servicer shall use reasonable efforts, to the extent that it has actual
knowledge of such conveyance, to enforce any due-on-sale clause contained in any
Mortgage Note or Mortgage, to the extent permitted under applicable law and
governmental regulations, but only to the extent that such enforcement will not
adversely affect or jeopardize coverage under any Required Insurance Policy.
Notwithstanding the foregoing, the Servicer is not required to exercise such
rights with respect to a Mortgage Loan if the Person to whom the related
Mortgaged Property has been conveyed or is proposed to be conveyed satisfies the
terms and conditions contained in the Mortgage Note and Mortgage related thereto
and the consent of the mortgagee under such Mortgage Note or Mortgage is not
otherwise required under such Mortgage Note or Mortgage as a condition to such
transfer. If (i) the Servicer is prohibited by law from enforcing any such
due-on-sale clause, (ii) coverage under any Required Insurance Policy would be
adversely affected, (iii) the Mortgage Note does not include a due-on-sale
clause or (iv) nonenforcement is otherwise permitted hereunder, the Servicer is
authorized, subject to Section 3.13(b), to take or enter into an assumption and
modification agreement from or with the Person to whom such Mortgaged Property
has been or is about to be conveyed, pursuant to which such Person becomes
liable under the Mortgage Note and, unless prohibited by applicable state law,
the Mortgagor remains liable thereon; provided that the Mortgage Loan shall
continue to be covered (if so covered before the Servicer enters such agreement)
by the applicable Required Insurance Policies. The Servicer, subject to Section
3.13(b), is also authorized with the prior approval of the insurers under any
Required Insurance Policies to enter into a substitution of liability agreement
with such Person, pursuant to which the original Mortgagor is released from
liability and such Person is substituted as Mortgagor and becomes liable under
the Mortgage Note. Notwithstanding the foregoing, the Servicer shall not be
deemed to be in default under this Section 3.13 by reason of any transfer or
assumption which the Servicer reasonably believes it is restricted by law from
preventing, for any reason whatsoever.

            (b) Subject to the Servicer's duty to enforce any due-on-sale clause
   to the extent set forth in Section 3.13(a), in any case in which a Mortgaged
   Property has been conveyed to a Person by a Mortgagor, and such Person is to
   enter into an assumption agreement or modification agreement or supplement to
   the Mortgage Note or Mortgage or if an instrument of release is required
   releasing the Mortgagor from liability on the Mortgage Loan, the Servicer
   shall prepare and execute the assumption agreement with the Person to whom
   the Mortgaged Property is to be conveyed and such modification agreement or
   supplement to the Mortgage Note or Mortgage or other instruments as are
   reasonable or necessary to carry out the terms of the Mortgage Note or
   Mortgage or otherwise to comply with any applicable laws regarding
   assumptions or the transfer of the Mortgaged Property to such Person. In
   connection with any such assumption, no material term of the Mortgage Note
   may be changed. In addition, the substitute Mortgagor and the Mortgaged
   Property must be acceptable to the Servicer in accordance with its
   underwriting standards as then in effect. Together with each such
   substitution, assumption or other agreement or instrument, the Servicer shall
   execute an Officer's Certificate signed by a Servicing Officer stating that
   the requirements of this subsection have been met. The Servicer shall notify
   the Trustee that any such substitution or assumption agreement has been
   completed by forwarding to the Trustee (or at the direction of the Trustee,
   the Custodian) the Officer's Certificate described in the previous sentence
   and the original of such substitution or assumption agreement, which in the
   case of the original shall be added to the related Mortgage File and shall,
   for all purposes, be considered a part of such Mortgage File to the same
   extent as all other documents and instruments constituting a part thereof.
   Any fee collected by the Servicer for entering into an assumption or
   substitution of liability agreement may be retained by the Servicer as
   additional Servicing Compensation.

             Section 3.14 Realization Upon Defaulted Mortgage Loans; REO
Property. Subject to Section 3.21, the Servicer shall use reasonable efforts 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. In connection with such foreclosure or other conversion,
the Servicer shall follow Customary Servicing Procedures and shall meet the
requirements of the insurer under any Required Insurance Policy; provided,
however, that the Servicer may enter into a special servicing agreement with an
unaffiliated Holder of 100% Percentage Interest of a Class of Subordinate
Certificates or a holder of a class of securities representing interests in the
Subordinate Certificates alone or together with other subordinated mortgage
pass-through certificates. Such agreement shall be substantially in the form
attached hereto as Exhibit K or subject to each Rating Agency's acknowledgment
that the ratings of the Certificates in effect immediately prior to the entering
into such agreement would not be qualified, downgraded or withdrawn and the
Certificates would not be placed on credit review status (except for possible
upgrading) as a result of such agreement. Any such agreement may contain
provisions whereby such holder may instruct the Servicer to commence or delay
foreclosure proceedings with respect to delinquent Mortgage Loans and will
contain provisions for the deposit of cash by the holder that would be available
for distribution to Certificateholders if Liquidation Proceeds are less than
they otherwise may have been had the Servicer acted in accordance with its
normal procedures. Notwithstanding the foregoing, the Servicer shall not be
required to expend its own funds in connection with any foreclosure or towards
the restoration of any Mortgaged Property unless it shall determine (i) that
such restoration and/or foreclosure will increase the proceeds of liquidation of
the Mortgage Loan after reimbursement to itself of such expenses and (ii) that
such expenses will be recoverable to it through proceeds of the liquidation of
the Mortgage Loan (respecting which it shall have priority for purposes of
withdrawals from the Servicer Custodial Account). Any such expenditures shall
constitute Servicing Advances for purposes of this Agreement.

            With respect to any REO Property, the deed or certificate of sale
shall be taken in the name of the Trustee for the benefit of the
Certificateholders, or its nominee, on behalf of the Certificateholders. The
Trustee's name shall be placed on the title to such REO Property solely as the
Trustee hereunder and not in its individual capacity. The Servicer shall ensure
that the title to such REO Property references this Agreement and the Trustee's
capacity hereunder. Pursuant to its efforts to sell such REO Property, the
Servicer shall either itself or through an agent selected by the Servicer
manage, conserve, protect and operate such REO Property in the same manner that
it manages, conserves, protects and operates other foreclosed property for its
own account and in the same manner that similar property in the same locality as
the REO Property is managed. Incident to its conservation and protection of the
interests of the Certificateholders, the Servicer may rent the same, or any part
thereof, as the Servicer deems to be in the best interest of the
Certificateholders for the period prior to the sale of such REO Property. The
Servicer shall prepare for and deliver to the Trustee a statement with respect
to each REO Property that has been rented, if any, showing the aggregate rental
income received and all expenses incurred in connection with the management and
maintenance of such REO Property at such times as is necessary to enable the
Trustee to comply with the reporting requirements of the REMIC Provisions;
provided, however, that the Servicer shall have no duty to rent any REO Property
on behalf of the Trust. The net monthly rental income, if any, from such REO
Property shall be deposited in the Servicer Custodial Account no later than the
close of business on each Determination Date. The Servicer shall perform, with
respect to the Mortgage Loans, the tax reporting and withholding required by
Sections 1445 and 6050J of the Code with respect to foreclosures and
abandonments, the tax reporting required by Section 6050H of the Code with
respect to the receipt of mortgage interest from individuals and, if required by
Section 6050P of the Code with respect to the cancellation of indebtedness by
certain financial entities, by preparing such tax and information returns as may
be required, in the form required.

            If the Trust acquires any Mortgaged Property as described above or
otherwise in connection with a default or a default which is reasonably
foreseeable on a Mortgage Loan, the Servicer shall dispose of such Mortgaged
Property prior to the end of the third calendar year following the year of its
acquisition by the Trust (such period, the "REO Disposition Period") unless (A)
the Trustee shall have been supplied by the Servicer with an Opinion of Counsel
to the effect that the holding by the Trust of such Mortgaged Property
subsequent to the REO Disposition Period will not result in the imposition of
taxes on "prohibited transactions" (as defined in Section 860F of the Code) on
either REMIC 1 or REMIC 2 or cause either REMIC created hereunder to fail to
qualify as a REMIC at any time that any Certificates are outstanding, or (B) the
Trustee (at the Servicer's expense) or the Servicer shall have applied for,
prior to the expiration of the REO Disposition Period, an extension of the REO
Disposition Period in the manner contemplated by Section 856(e)(3) of the Code.
If such an Opinion of Counsel is provided or such an exemption is obtained, the
Trust may continue to hold such Mortgaged Property (subject to any conditions
contained in such Opinion of Counsel) for the applicable period. Notwithstanding
any other provision of this Agreement, no Mortgaged Property acquired by the
Trust shall 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 or (ii) subject either 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 Servicer has
agreed to indemnify and hold harmless the Trust with respect to the imposition
of any such taxes. The Servicer shall identify to the Trustee any Mortgaged
Property relating to a Mortgage Loan held by the Trust for 30 months for which
no plans to dispose of such Mortgaged Property by the Servicer have been made.
After delivery of such identification, the Servicer shall proceed to dispose of
any such Mortgaged Property by holding a commercially reasonable auction for
such property.

            The income earned from the management of any REO Properties, net of
reimbursement to the Servicer for expenses incurred (including any property or
other taxes) in connection with such management and net of unreimbursed
Servicing Fees, Periodic Advances and Servicing Advances, shall be applied to
the payment of principal of and interest on the related defaulted Mortgage Loans
(solely for the purposes of allocating principal and interest, interest shall be
treated as accruing as though such Mortgage Loans were still current) and all
such income shall be deemed, for all purposes in this Agreement, to be payments
on account of principal and interest on the related Mortgage Notes and shall be
deposited into the Servicer Custodial Account. To the extent the net income
received during any calendar month is in excess of the amount attributable to
amortizing principal and accrued interest at the related Mortgage Interest Rate
on the related Mortgage Loan for such calendar month, such excess shall be
considered to be a partial prepayment of principal of the related Mortgage Loan.

            The proceeds from any liquidation of a Mortgage Loan, as well as any
income from an REO Property, will be applied in the following order of priority:
first, to reimburse the Servicer for any related unreimbursed Servicing Advances
and Servicing Fees; second, to reimburse the Servicer for any unreimbursed
Periodic Advances and to reimburse the Servicer Custodial Account for any
Nonrecoverable Advances (or portions thereof) that were previously withdrawn by
the Servicer pursuant to Section 3.11(a)(iii) that related to such Mortgage
Loan; third, to accrued and unpaid interest (to the extent no Periodic Advance
has been made for such amount or any such Periodic Advance has been reimbursed)
on the Mortgage Loan or related REO Property, at the Mortgage Interest Rate to
the Due Date occurring in the month in which such amounts are required to be
distributed; and fourth, as a recovery of principal of the Mortgage Loan. Excess
Proceeds, if any, from the liquidation of a Liquidated Mortgage Loan will be
retained by the Servicer as additional Servicing Compensation pursuant to
Section 3.17.

            Section 3.15 Trustee to Cooperate; Release of Mortgage Files. Upon
the payment in full of any Mortgage Loan, or the receipt by the Servicer of a
notification that payment in full will be escrowed in a manner customary for
such purposes, the Servicer will immediately notify the Trustee (or, at the
direction of the Trustee, 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 Trustee and the Servicer). Upon receipt of such
request, the Trustee or the Custodian, as applicable, shall within seven
Business Days release the related Mortgage File to the Servicer. The Trustee
shall deliver to the Servicer the Mortgage Note with written evidence of
cancellation thereon. If the Mortgage has been recorded in the name of MERS or
its designee, the Servicer shall 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. 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 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 Trustee or the Custodian, as applicable,
shall, upon delivery to the Trustee (or, at the direction of the Trustee, the
Custodian) of a Request for Release signed by a Servicing Officer, release the
Mortgage File within seven Business Days to the Servicer. Subject to the further
limitations set forth below, the Servicer shall cause the Mortgage File so
released to be returned to the Trustee or the Custodian, as applicable, when the
need therefor by the Servicer 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 Trustee or the
Custodian, as applicable, a Request for Release, signed by a Servicing Officer.

            Upon prepayment in full of any Mortgage Loan or the receipt of
notice that funds for such purpose have been placed in escrow, the Servicer
shall give an instrument of satisfaction (or Assignment of Mortgage without
recourse) regarding the Mortgaged Property relating to such Mortgage Loan, which
instrument of satisfaction or Assignment of Mortgage, as the case may be, shall
be delivered to the Person entitled thereto against receipt of the prepayment in
full. If the Mortgage is registered in the name of MERS or its designee, the
Servicer shall take all necessary action to reflect the release on the records
of MERS. In lieu of executing such satisfaction or Assignment of Mortgage, or if
another document is required to be executed by the Trustee, the Servicer may
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 3.16 Documents, Records and Funds in Possession of the
Servicer to Be Held for the Trustee. The Servicer shall transmit to the Trustee
or, at the direction of the Trustee, the Custodian as required by this 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 Servicer or which otherwise are collected
by the Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any
Mortgage Loan. The documents constituting the Servicing File shall be held by
the Servicer as custodian and bailee for the Trustee. All Mortgage Files and
funds collected or held by, or under the control of, 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 Servicer Custodial Account, shall be held by 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.
The Servicer also agrees that it shall not knowingly create, incur or subject
any Mortgage File or any funds that are deposited in the Servicer Custodial
Account, 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 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 Servicer shall be entitled to set off against and deduct from any such
funds any amounts that are properly due and payable to the Servicer under this
Agreement.

            Section 3.17 Servicing Compensation. The Servicer shall be entitled
out of each payment of interest on a Mortgage Loan (or portion thereof) and
included in the Trust Estate to retain or withdraw from the Servicer Custodial
Account an amount equal to the Servicing Fee for such Distribution Date;
provided, however, that the aggregate Servicing Fee for the Servicer relating to
the Mortgage Loans shall be reduced (but not below zero) by an amount equal to
the Compensating Interest.

            Any additional Servicing Compensation shall be retained by the
Servicer to the extent not required to be deposited in the Servicer Custodial
Account pursuant to Section 3.08(b). The Servicer shall be required to pay all
expenses incurred by it in connection with its servicing activities hereunder
and shall not be entitled to reimbursement therefor except as specifically
provided in this Agreement.

            Section 3.18 Annual Statement as to Compliance. The Trustee and the
Servicer shall deliver, and the Servicer shall cause each Additional Servicer
engaged by it to deliver, in electronic form to the Depositor, the Trustee and
each Rating Agency on or before March 5 of each year or if such day is not a
Business Day, the next Business Day (with a 10 calendar day cure period, but in
no event later than March 15), followed by a hard copy within 10 calendar days,
commencing in March 2007, a certificate in the form required by Item 1123 of
Regulation AB, to the effect that (i) an authorized officer of the Trustee, the
Servicer or the Additional Servicer, as the case may be, has reviewed (or a
review has been made under his or her supervision of) such party's activities
under this Agreement or such other applicable agreement in the case of an
Additional Servicer, during the prior calendar year or portion thereof and (ii)
to the best of such officer's knowledge, based on such review, such party has
fulfilled all of its obligations under this Agreement, or such other applicable
agreement in the case of an Additional Servicer, in all material respects
throughout the prior calendar year or portion thereof or, if there has been a
failure to fulfill any such obligation in any material respect, specifying each
such failure known to such officer and the nature and status thereof. Promptly
after receipt of each such certificate, the Depositor shall review such
certificate and, if applicable, consult with the Servicer and the Trustee as to
the nature of any failure to fulfill any obligation under the Agreement, or such
other applicable agreement in the case of an Additional Servicer, in any
material respect.

            Section 3.19 Assessments of Servicing Compliance; Registered Public
            Accounting Firm Attestation Reports. (a) Each of the Servicer and
   the Trustee,
at its own expense, shall furnish, and shall cause any Servicing Function
Participant engaged by it to furnish, at such party's expense, to the Trustee
and the Depositor in electronic form, not later than March 5 of each year or if
such day is not a Business Day, the next Business Day (with a 10 calendar day
cure period, but in no event later than March 15), followed by a hard copy
within 10 calendar days, commencing in March 2007, a report on an assessment of
compliance with the Servicing Criteria applicable to it that contains (A) a
statement by such party of its responsibility for assessing compliance with the
Servicing Criteria applicable to it, (B) a statement that such party used the
Servicing Criteria to assess compliance with the Servicing Criteria applicable
to it, (C) such party's assessment of compliance with the Servicing Criteria
applicable to it as of and for the fiscal year covered by the Form 10-K required
to be filed pursuant to Section 3.22, including, if there has been any material
instance of noncompliance with the Servicing Criteria applicable to it, an
identification of each such failure and the nature and status thereof, and (D) a
statement that a registered public accounting firm has issued an attestation
report on such party's assessment of compliance with the Servicing Criteria
