    CONVEYANCE
      OF MORTGAGE LOANS
    Section
      1.01. Sale
      of Mortgage Loans.
    (a) Sale
      of Mortgage Loans.
      Concurrently with the execution and delivery of this Agreement, the Seller
      does
      hereby transfer, assign, set over, deposit with and otherwise convey to the
      Depositor, without recourse, subject to Sections 1.03 and 1.04 of this

      Mortgage Loans identified on Schedules A and Schedule B hereto, having an
      approximate aggregate principal balance as of the Cut-off Date of
      $754,351,721.79. Such conveyance includes, without limitation, the right to
      all
      distributions of principal and interest received on or with respect to the
      Mortgage Loans on and after the Cut-off Date, other than payments of principal
      and interest due on or before such date, and all such payments due after such
      date but received prior to such date and intended by the related Mortgagors
      to
      be applied after such date, all Prepayment Charges received on or with respect
      to the Mortgage Loans on or after the Cut-off Date, together with all of the
      Seller’s right, title and interest in and to each related account and all
      amounts from time to time credited to and the proceeds of such account, any
      REO
      Property and the proceeds thereof, the Seller’s rights under any Insurance
      Policies relating to the Mortgage Loans, the Seller’s security interest in any
      collateral pledged to secure the Mortgage Loans, including the Mortgaged
      Properties and any proceeds of the foregoing. 
    Concurrently
      with the execution and delivery of this Agreement, the Seller hereby assigns
      to
      the Depositor all of its rights and interest under each Transfer Agreement
      (except for any rights against the related Transferor with respect to first
      payment date defaults or early payment date defaults) and each Servicing
      Agreement, other than any servicing rights retained thereunder, and delegates
      to
      the Depositor all of its obligations thereunder, to the extent relating to
      the
      Mortgage Loans. The Seller and the Depositor further agree that this Agreement
      incorporates the terms and conditions of any assignment and assumption agreement
      or other assignment document required to be entered into under any of the
      Transfer Agreements (any such document an “Assignment Agreement”) and that this
      Agreement constitutes an Assignment Agreement under such Transfer Agreement,
      and
      the Depositor hereby assumes the obligations of the assignee under each such
      Assignment Agreement. Concurrently with the execution hereof, the Depositor
      tenders the purchase price set forth in that certain Terms Letter dated as
      of
      the date hereof, a form of which is attached as Exhibit B hereto (the “Purchase
      Price”). The Depositor hereby accepts such assignment and delegation, and shall
      be entitled to exercise all the rights of the Seller under each Transfer
      Agreement and each Servicing Agreement, other than any servicing rights
      thereunder, as if the Depositor had been a party to each such
      agreement.
    4
        (b) Schedules
      of Mortgage Loans. The
      Depositor and the Seller have agreed upon which of the Mortgage Loans owned
      by
      the Seller are to be purchased by the Depositor pursuant to this Agreement
      and
      the Seller will prepare on or prior to the Closing Date a final schedule
      describing such Mortgage Loans (the “Mortgage Loan Schedule”). The Mortgage Loan
      Schedule shall conform to the requirements of the Depositor as set forth in
      this
      Agreement and to the definition of “Mortgage Loan Schedule” under the Trust
      Agreement. The Mortgage Loan Schedule attached hereto as Schedule A specifies
      those Mortgage Loans that are Transferred Mortgage Loans and the Mortgage Loan
      Schedule attached hereto as Schedule B specifies those Mortgage Loans that
      are
      Bank Originated Loans, each of which categories of Mortgage Loans have been
      assigned by the Bank to the Seller pursuant to the Assignment and Assumption
      Agreement.
    Section

      the Seller shall, at least three (3) Business Days prior to the Closing Date,
      deliver, or cause to be delivered, to the Depositor (or its designee) the
      documents or instruments with respect to each Mortgage Loan (each, a “Mortgage
      File”) so transferred and assigned, as specified in the related Transfer
      Agreements or Servicing Agreements. 
    (b) For
      Mortgage Loans (if any) that have been prepaid in full on or after the Cut-off
      Date and prior to the Closing Date, the Seller, in lieu of delivering the
      related Mortgage Files, herewith delivers to the Depositor an Officer’s
      Certificate which shall include a statement to the effect that all amounts
      received in connection with such prepayment that are required to be deposited
      in
      the account maintained by the Servicer for such purpose have been so
      deposited.
    Section
      1.03. Review
      of Documentation.
    The
      Depositor, by execution and delivery hereof, acknowledges receipt of the
      Mortgage Files pertaining to the Mortgage Loans listed on the Mortgage Loan
      Schedule, subject to review thereof by U.S. Bank National Association, Deutsche
      Bank National Trust Company, LaSalle Bank National Association and ▇▇▇▇▇ Fargo
      Bank, N.A., as the custodians (each, a “Custodian” and together, the
“Custodians”), for the applicable Mortgage Loans for the Depositor. Each
      Custodian is required to review, within 45 days following the Closing Date,
      each
      applicable Mortgage File. If in the course of such review the related Custodian
      identifies any Material Defect, the Seller shall be obligated to cure such
      Material Defect or to repurchase the related Mortgage Loan from the Depositor
      (or, at the direction of and on behalf of the Depositor, from the Trust Fund),
      or to substitute a Qualifying Substitute Mortgage Loan therefor, in each case
      to
      the same extent and in the same manner as the Depositor is obligated to the
      Trustee and the Trust Fund under Section 2.02(c) of the Trust Agreement.

      and delivery by the Bank, in the case of the Assignment and Assumption
      Agreement, and the Depositor, in the case of this Agreement, constitutes a
      valid
      and binding obligation of the Seller enforceable against it in accordance with
      its respective terms, except as such enforceability may be subject to (A)
      applicable bankruptcy and insolvency laws and other similar laws affecting
      the
      enforcement of the rights of creditors generally and (B) general principles
      of
      equity regardless of whether such enforcement is considered in a proceeding
      in
      equity or at law; and
    (v) there
      are
      no actions, suits or proceedings pending or, to the knowledge of the Seller,
      threatened or likely to be asserted against or affecting the Seller, before
      or
      by any court, administrative agency, arbitrator or governmental body (A) with
      respect to any of the transactions contemplated by the Assignment and Assumption
      Agreement or this Agreement or (B) with respect to any other matter which in
      the
      judgment of the Seller will be determined adversely to the Seller and will
      if
      determined adversely to the Seller materially and adversely affect it or its
      business, assets, operations or condition, financial or otherwise, or adversely
      affect its ability to perform its obligations under the Assignment and
      Assumption Agreement or this Agreement.
    6
        (b) The
      representations and warranties of each Transferor with respect to the Mortgage
      Loans in the applicable Transfer Agreement were made as of the date of such
      Transfer Agreement. To the extent that any fact, condition or event with respect
      to a Transferred Mortgage Loan constitutes a breach of both (i) a representation
      or warranty of a Transferor under the applicable Transfer Agreement and (ii)
      a
      representation or warranty of the Seller under this Agreement, the sole right
      or
      remedy of the Depositor with respect to a breach by the Seller of such
      representation and warranty (other than a breach by the Seller of the
      representations made by it pursuant to Sections 1.04(b)(xii)¸(xiii), (xiv),
      (xv), (xvii) and (xviii), shall be the right to enforce the obligations of
      such
      Transferor under any applicable representation or warranty made by it. The
      representations made by the Seller pursuant to Sections 1.04(b)(xii), (xiii),
      (xiv), (xv), (xvii) and (xviii) shall be direct obligations of the Seller.
      The
      Depositor acknowledges and agrees that the representations and warranties of
      the
      Seller in this Section 1.04(b) (other than those representations and warranties
      made pursuant to Sections 1.04(b)(xii), (xiii), (xiv), (xv), (xvii) and (xviii))
      are applicable only to facts, conditions or events that do not constitute a
      breach of any representation or warranty made by the related Transferor in
      the
      applicable Transfer Agreement. The Seller shall have no obligation or liability
      with respect to any breach of a representation or warranty made by it with
      respect to the Transferred Mortgage Loans (except in the case of those
      representation and warranties made by it pursuant to 1.04(b)(xii), (xiii),
      (xiv), (xv), (xvii) and (xviii)) if the fact, condition or event constituting
      such breach also constitutes a breach of a representation or warranty made
      by
      the related Transferor in such Transfer Agreement, without regard to whether
      the
      related Transferor fulfills its contractual obligations in respect of such
      representation or warranty; provided,
      however,
      that if
      the related Transferor fulfills its obligations under the provisions of such
      Transfer Agreement by substituting for the affected Mortgage Loan a mortgage
      loan which is not a Qualifying Substitute Mortgage Loan, the Seller shall,
      in
      exchange for such substitute mortgage loan, provide the Depositor (a) with
      the
      applicable Purchase Price for the affected Mortgage Loan or (b) within the
      two-year period following the Closing Date, with a Qualified Substitute Mortgage
      Loan for such affected Mortgage Loan. 
    Subject
      to the foregoing, the Seller represents and warrants upon delivery of the
      Transferred Mortgage Loans to the Depositor hereunder, as to each, that, as
      of
      the Closing Date:
    (i) The
      information set forth with respect to the Transferred Mortgage Loans on the
      Mortgage Loan Schedule provides an accurate listing of the Transferred Mortgage
      Loans, and the information with respect to each Transferred Mortgage Loan on
      the
      Mortgage Loan Schedule is true and correct in all material respects at the
      date
      or dates respecting which such information is given;
    (ii) There
      are
      no defaults (other than delinquency in payment) in complying with the terms
      of
      any Mortgage, and the Seller has no notice as to any taxes, governmental
      assessments, insurance premiums, water, sewer and municipal charges, leasehold
      payments or ground rents which previously became due and owing but which have
      not been paid;
    (iii) Except
      in
      the case of Cooperative Loans, if any, each Mortgage requires all buildings
      or
      other improvements on the related Mortgaged Property to be insured by a
      generally acceptable insurer against loss by fire, hazards of extended coverage
      and such other hazards as are customary in the area where the related Mortgaged
      Property is located pursuant to insurance policies conforming to the
      requirements of the guidelines of ▇▇▇▇▇▇ ▇▇▇ or ▇▇▇▇▇▇▇ Mac. If upon origination
      of the Transferred Mortgage Loan, the Mortgaged Property was 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)
      a flood insurance policy meeting the requirements of the current guidelines
      of
      the Federal Flood Insurance Administration is in effect which policy conforms
      to
      the requirements of the current guidelines of the Federal Flood Insurance
      Administration. Each Mortgage obligates the related Mortgagor thereunder to
      maintain the hazard insurance policy at the Mortgagor’s cost and expense, and on
      the Mortgagor’s failure to do so, authorizes the holder of the Mortgage to
      obtain and maintain such insurance at such Mortgagor’s cost and expense, and to
      seek reimbursement therefor from the Mortgagor. Where required by state law
      or
      regulation, each Mortgagor has been given an opportunity to choose the carrier
      of the required hazard insurance, provided the policy is not a “master” or
“blanket” hazard insurance policy covering the common facilities of a planned
      unit development. The hazard insurance policy is the valid and binding
      obligation of the insurer, is in full force and effect, and will be in full
      force and effect and inure to the benefit of the Depositor upon the consummation
      of the transactions contemplated by this Agreement;
    7
        (iv) Each
      Mortgage has not been satisfied, cancelled, subordinated or rescinded, in whole
      or in part, 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 release, cancellation, subordination or
      rescission;
    (v) Each
      Mortgage evidences a valid, subsisting, enforceable and perfected first lien
      on
      the related Mortgaged Property (including all improvements on the Mortgaged
      Property). The lien of the Mortgage is subject only to: (1) liens of current
      real property taxes and assessments not yet due and payable and, if the related
      Mortgaged Property is a condominium unit, any lien for common charges permitted
      by statute, (2) covenants, conditions and restrictions, rights of way, easements
      and other matters of public record as of the date of recording of such Mortgage
      acceptable to mortgage lending institutions in the area in which the related
      Mortgaged Property is located and specifically referred to in the lender’s Title
      Insurance Policy or attorney’s opinion of title and abstract of title delivered
      to the originator of such Transferred Mortgage Loan, and (3) such other matters
      to which like properties are commonly subject which do not, individually or
      in
      the aggregate, materially interfere with the benefits of the security intended
      to be provided by the Mortgage. Any security agreement, chattel mortgage or
      equivalent document related to, and delivered to the Trustee in connection
      with
      a Transferred Mortgage Loan establishes a valid, subsisting and enforceable
      first lien on the property described therein and the Depositor has full right
      to
      sell and assign the same to the Trustee;
    (vi) Immediately
      prior to the transfer and assignment of the Transferred Mortgage Loans to the
      Depositor, the Seller was the sole owner of record and holder of each Mortgage
      Loan, and the Seller had good and marketable title thereto, and has full right
      to transfer and sell each Transferred Mortgage Loan to the Depositor free and
      clear, except as described in paragraph (v) above, of any encumbrance, equity,
      participation interest, lien, pledge, charge, claim or security interest, and
      has full right and authority, subject to no interest or participation of, or
      agreement with, any other party, to sell and assign each Transferred Mortgage
      Loan pursuant to this Agreement;
    8
        (vii) Each
      Transferred Mortgage Loan other than any Cooperative Loan is covered by either
      (i) an attorney’s opinion of title and abstract of title the form and substance
      of which is generally acceptable to mortgage lending institutions originating
      mortgage loans in the locality where the related Mortgaged Property is located
      or (ii) an ALTA Mortgagee Title Insurance Policy or other generally acceptable
      form of policy of insurance, issued by a title insurer qualified to do business
      in the jurisdiction where the Mortgaged Property is located, insuring the
      originator of the Transferred Mortgage Loan, and its successors and assigns,
      as
      to the first priority lien of the Mortgage in the original principal amount
      of
      the Transferred Mortgage Loan (subject only to the exceptions described in
      paragraph (v) above). If the Mortgaged Property is a condominium unit located
      in
      a state in which a title insurer will generally issue an endorsement, then
      the
      related Title Insurance Policy contains an endorsement insuring the validity
      of
      the creation of the condominium form of ownership with respect to the project
      in
      which such unit is located. With respect to any Title Insurance Policy, the
      originator is the sole insured of such mortgagee Title Insurance Policy, such
      mortgagee Title Insurance Policy is in full force and effect and will inure
      to
      the benefit of the Depositor upon the consummation of the transactions
      contemplated by this Agreement, no claims have been made under such mortgagee
      Title Insurance Policy and no prior holder of the related Mortgage, including
      the Seller, has done, by act or omission, anything that would impair the
      coverage of such mortgagee Title Insurance Policy;
    (viii) To
      the
      best of the Seller’s knowledge, no foreclosure action is being threatened or
      commenced with respect to any Transferred Mortgage Loan. There is no proceeding
      pending for the total or partial condemnation of any Mortgaged Property (or,
      in
      the case of any Cooperative Loan, the related cooperative unit) and each such
      property is undamaged by waste, fire, earthquake or earth movement, windstorm,
      flood, tornado or other casualty, so as to have a material adverse effect on
      the
      value of the related Mortgaged Property as security for the related Transferred
      Mortgage Loan or the use for which the premises were intended;
    (ix) There
      are
      no mechanics’ or similar liens or claims which have been filed for work, labor
      or material (and no rights are outstanding that under the law could give rise
      to
      such liens) affecting the related Mortgaged Property which are or may be liens
      prior to, or equal or coordinate with, the lien of the related
      Mortgage;
    (x) Each
      Transferred Mortgage Loan was originated by a savings and loan association,
      savings bank, commercial bank, credit union, insurance company, or similar
      institution that 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; 
    9
        (xi) Each
      Transferred Mortgage Loan is a “qualified mortgage” within the meaning of
      Section 860G of the Code and Treas. Reg. §1.860G-2;
    (xii) Each
      Transferred Mortgage Loan, at the time it was originated, complied in all
      material respects with applicable local, state and federal laws, including,
      but
      not limited to, all applicable local, state and federal predatory and abusive
      lending laws;
    (xiii) No
      Transferred Mortgage Loan is a “High Cost Loan” or “Covered Loan,” as
      applicable, as such terms are defined in the then current Standard & Poor’s
      LEVELS® Glossary. In addition, no Transferred Mortgage Loan is a “high-cost,”
“high-cost home,” “covered,” “high-risk home,” or “predatory” loan under any
      applicable federal, state or local predatory or abusive lending law (or a
      similarly classified loan using different terminology under a law imposing
      heightened regulatory scrutiny or additional legal liability for residential
      mortgage loans having high interest rates, points and/or fees);
    (xiv) No
      Transferred Mortgage Loan was at the time of origination subject to the Home
      Ownership and Equity Protection Act of 1994 (15 U.S.C. § 1602(c)),
      Regulation Z (12 CFR 226.32) or any comparable state law; 
    (xv) No
      Transferred Mortgage Loan was originated (or modified) on or after March 1,
      2002
      and before March 7, 2003 which is secured by a mortgaged property located in
      Georgia; 
    (xvi) [Reserved];
      and
    (xvii) The
      information set forth in the Prepayment Charge Schedules included as part of
      the
      Mortgage Loan Schedules at Schedules A and B (including the Prepayment Charge
      Summary attached thereto) is complete, true and correct in all material respects
      on the date or dates on which such information is furnished and each Prepayment
      Charge is permissible, originated in compliance with, and enforceable in
      accordance with its terms under, applicable federal, state and local law (except
      to the extent that the enforceability thereof may be limited by bankruptcy,
      insolvency, moratorium, receivership and other similar laws affecting creditor’s
      rights generally or the collectibility thereof may be limited due to
      acceleration in connection with foreclosure). 
    (c) In
      addition to the representations and warranties set forth in Section 1.04(b),
      all
      of which are also made by the Seller with respect to the Bank Originated
      Mortgage Loans as of the Closing Date, the Seller hereby further represents
      and
      warrants to the Depositor upon the delivery to the Depositor on the Closing
      Date
      of any Bank Originated Mortgage Loans, but solely as to each Bank Originated
      Mortgage Loan, that, as of the Closing Date:
    10
        (xviii) With
      respect to any hazard insurance policy covering a Bank Originated Mortgage
      Loan
      and the related Mortgaged Property, the Seller has not engaged in, and has
      no
      knowledge of the Bank’s or the borrower’s having engaged in, any act or omission
      which would impair the coverage of any such policy, the benefits of the
      endorsement provided for therein, or the validity and binding effect of either,
      including without limitation, no unlawful fee, commission, kickback or other
      unlawful compensation or value of any kind has been or will be received,
      retained or realized by any attorney, firm or other person or entity, and no
      such unlawful items have been received, retained or realized by the
      Seller;
    (xix) Neither
      the Seller nor the Bank has waived the performance by the borrower of any
      action, if the Mortgagor’s failure to perform such action would cause a Bank
      Originated Mortgage Loan to be in default, nor has the Seller or the Bank waived
      any default resulting from any action or inaction by the borrower;
    (xx) The
      terms
      of the Mortgage Note and Mortgage have not been impaired, waived, altered or
      modified in any respect, except by a written instrument which has been recorded,
      if necessary to protect the interests of the Depositor and which has been
      delivered to the Custodian;
    (xxi) The
      Mortgaged Property relating to each Bank Originated Mortgage Loan is a fee
      simple property (or in the case of certain property situated in Hawaii, property
      held under long-term residential lease) 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 in a low-rise condominium project, an individual
      unit in a planned unit development or shares issued by cooperative housing
      corporations and related leasehold interests; provided,
      however,
      that
      any condominium project or planned unit development shall conform with the
      applicable ▇▇▇▇▇▇ ▇▇▇ and ▇▇▇▇▇▇▇ Mac requirements regarding such dwellings.
      No
      portion of the Mortgaged Property is used for commercial purposes;
    (xxii) The
      Mortgage Note and the Mortgage are genuine, and each is the legal, valid and
      binding obligation of the maker thereof enforceable in accordance with its
      terms. All parties to the Mortgage Note and the Mortgage and any other related
      agreement had legal capacity to enter into the Bank Originated Mortgage Loan
      and
      to execute and deliver the Mortgage Note and the Mortgage and any other related
      agreement, and the Mortgage Note and the Mortgage have been duly and properly
      executed by such parties. The documents, instruments and agreements submitted
      for loan underwriting were not falsified and contain no untrue statement of
      material fact or omit to state a material fact required to be stated therein
      or
      necessary to make the information and statements therein not misleading. To
      the
      best of Seller’s knowledge, no fraud was committed in connection with the
      origination of the Bank Originated Mortgage Loan;
    (xxiii) Each
      Bank
      Originated Mortgage Loan has been closed and the proceeds of the Bank Originated
      Mortgage Loan have been fully disbursed and there is no requirement for future
      advances thereunder, and any and all requirements as to completion of any
      on-site or off-site improvement and as to disbursements of any escrow funds
      therefor have been complied with. All costs, fees and expenses incurred in
      making or closing the Bank Originated Mortgage Loan and the recording of the
      Mortgage were paid, and the borrower is not entitled to any refund of any
      amounts paid or due under the Mortgage Note or Mortgage;
    11
        (xxiv) There
      is
      no default (other than delinquency in payment), 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 neither the Seller nor its predecessors has waived any
      default, breach, violation or event of acceleration;
    (xxv) All
      improvements which were considered in determining the Appraised Value of the
      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. No improvement located on or being part
      of
      the Mortgaged Property is in violation of any applicable zoning law or
      regulation;
    (xxvi) Each
      Mortgage contains customary and enforceable provisions which render the rights
      and remedies of the holder thereof adequate for the realization against the
      related Mortgaged Property of the benefits of the security, including (A) in
      the
      case of a Mortgage designated as a deed of trust, by trustee’s sale, and (B)
      otherwise by judicial or non-judicial foreclosure. There is no homestead or
      other exemption available to the related Mortgagor which would materially
      interfere with the right to sell the Mortgaged Property at a trustee’s sale or
      the right to foreclose the Mortgage subject to the applicable federal and state
      laws and judicial precedent with respect to bankruptcy and rights of redemption.
      Upon default by a Mortgagor on a Bank Originated Mortgage Loan and foreclosure
      on, or trustee’s sale of, the Mortgaged Property pursuant to the proper
      procedures, the holder of the Bank Originated Mortgage Loan will be able to
      deliver good and merchantable title to the property;
    (xxvii) The
      Mortgage Note is not and has not been secured by any collateral except the
      lien
      of the corresponding Mortgage and the security interest of any applicable
      security agreement or chattel mortgage;
    (xxviii) 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 is named in the Mortgage, and no fees or expenses are or will become
      payable by the Depositor to the trustee under the deed of trust, except in
      connection with a trustee’s sale after default by the Mortgagor;
    (xxix) The
      Mortgage Note, the Mortgage, the Assignment of Mortgage and any other documents
      required to be delivered for the Bank Originated Mortgage Loan by the Seller
      under this Agreement as set forth in Section 1.02 hereof have been delivered
      to
      the related Custodian. The Seller is in possession of a complete, true and
      accurate Mortgage File in compliance with Section 1.02 hereof, except for such
      documents the originals of which have been delivered to the related
      Custodian;
    12
        (xxx) The
      Assignment of Mortgage is in recordable form and is acceptable for recording
      under the laws of the jurisdiction in which the Mortgaged Property is
      located;
    (xxxi) The
      Mortgage contains an enforceable provision for the acceleration of the payment
      of the unpaid principal balance of the Bank Originated Mortgage Loan in the
      event that the Mortgaged Property is sold or transferred without the prior
      written consent of the Mortgagee thereunder;
    (xxxii) No
      Bank
      Originated Mortgage Loan contains provisions pursuant to which Monthly Payments
      are paid or partially paid with funds deposited in any separate account
      established by the Mortgagor or anyone on behalf of the Mortgagor, or paid
      by
      any source other than the Mortgagor, nor does any Bank Originated Mortgage
      Loan
      contain any other similar provisions currently in effect which may constitute
      a
“buydown” provision. No Bank Originated Mortgage Loan is a graduated payment
      mortgage loan and no Bank Originated Mortgage Loan has a shared appreciation
      or
      other contingent interest feature;
    (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 ▇▇▇▇▇▇ ▇▇▇ and ▇▇▇▇▇▇▇ Mac. The consolidated
      principal amount does not exceed the original principal amount of any Bank
      Originated Mortgage Loan;
    (xxxiv) The
      origination and collection practices used with respect to each Bank Originated
      Mortgage Loan have been in accordance with Accepted Servicing Practices, and
      have been in all respects in compliance with all applicable laws and
      regulations. With respect to escrow deposits and escrow payments, all such
      payments are in the possession of the Seller and there exist no deficiencies
      in
      connection therewith for which customary arrangements for repayment thereof
      have
      not been made. All escrow payments have been collected in full compliance with
      state and federal law. An escrow of funds is not prohibited by applicable law
      and has been established in an amount sufficient to pay for every item which
      remains unpaid and which has been assessed but is not yet due and payable.
      No
      escrow deposits or escrow payments or other charges or payments due the Seller
      have been capitalized under the Mortgage or the Mortgage Note. Any interest
      required to be paid pursuant to state and local law has been properly paid
      and
      credited;
    (xxxv) The
      Mortgage File contains an appraisal of the related Mortgage Property signed
      prior to the approval of the Bank Originated Mortgage Loan application by a
      qualified appraiser, who had no interest, direct or indirect in the Mortgaged
      Property or in any loan made on the security thereof; and whose compensation
      is
      not affected by the approval or disapproval of the Bank Originated Mortgage
      Loan, and the appraisal and appraiser both satisfy the requirements of Title
      XI
      of the Federal Institutions Reform, Recovery, and Enforcement Act of 1989 and
      the regulations promulgated thereunder, all as in effect on the date the Bank
      Originated Mortgage Loan was originated;
    13
        (xxxvi) The
      Mortgagor has not notified the Bank or the Seller, and neither the Bank nor
      the
      Seller has any knowledge of any relief requested or allowed to the Mortgagor
      under the Servicemembers’ Civil Relief Act;
    (xxxvii) The
      Mortgaged Property is free from any and all toxic or hazardous substances and
      there exists no violation of any local, state or federal environmental law,
      rule
      or regulation. There is no pending action or proceeding directly involving
      any
      Mortgaged Property of which the Seller is aware in which compliance with any
      environmental law, rule or regulation is an issue; and to the best of the
      Seller’s knowledge, nothing further remains to be done to satisfy in full all
      requirements of each such law, rule or regulation;
    (xxxviii) [Reserved];
    (xxxix) No
      Bank
      Originated Mortgage Loan was made in connection with (i) the construction or
      rehabilitation of a Mortgaged Property or (ii) facilitating the trade-in or
      exchange of a Mortgaged Property;
    (xl) No
      action, inaction or event has occurred and no state of facts exists or has
      existed that has resulted or will result in the exclusion from, denial of or
      defense to coverage under any applicable special hazard insurance policy,
      borrower-paid primary mortgage loan insurance policy or bankruptcy bond,
      irrespective of the cause of such failure of coverage. In connection with the
      placement of any such insurance, no commission, fee or other compensation has
      been or will be received by the Seller or any designee of the Seller or any
      corporation in which the Seller or any officer, director or employee had a
      financial interest at the time of placement of such insurance; and
    (xli) Each
      original Mortgage was recorded and, except for those Bank Originated Mortgage
      Loans subject to the MERS identification system, all subsequent assignments
      of
      the original Mortgage (other than the assignment to the Depositor) have been
      recorded in the appropriate jurisdictions wherein such recordation is necessary
      to perfect the liens thereof as against creditors of the Seller, or are in
      the
      process of being recorded.
    (d) With
      respect to any of the foregoing representations and warranties made in
      subparagraphs (xii), (xiii), (xiv), (xv), (xvii) and (xviii) of Section 1.04(b),
      a breach of any such representations or warranties shall be deemed to materially
      and adversely affect the value of the affected Mortgage Loan and the interests
      of Certificateholders therein, irrespective of the Seller’s knowledge of such
      breach. 
    14
        It
      is understood and agreed that the representations and warranties set forth
      in
      Sections 1.04(b) and 1.04(c) herein shall survive the Closing Date. Upon
      discovery by either the Seller or the Depositor of a breach of any of the
      foregoing representations and warranties (excluding a breach of subparagraph
      (xvii)
      under Section 1.04(b)), that adversely and materially affects the value of
      the
      related Mortgage Loan and that does not also constitute a breach of a
      representation or warranty of a Transferor in the related Transfer Agreement,
      the party discovering such breach shall give prompt written notice to the other
      party; provided,
      however,
      that notwithstanding anything to the contrary herein, this paragraph shall
      be
      specifically applicable to a breach by the Seller of the representations made
      pursuant to subparagraphs (xii),
      (xiii), (xiv), (xv), (xvii) and (xviii) of
      Section 1.04(b) irrespective of the Transferor’s breach of a comparable
      representation or warranty made in the related Transfer Agreement. Within 60
      days of the discovery of any such breach, the Seller shall either (a) cure
      such
      breach in all material respects, (b) repurchase such Mortgage Loan or any
      property acquired in respect thereof from the Depositor at the applicable
      Purchase Price or (c) within the two-year period following the Closing Date
      substitute a Qualifying Substitute Mortgage Loan for the affected Mortgage
      Loan.
    Notwithstanding
      the second paragraph of Section 1.04(d), in connection with the Seller’s
      representations and warranties made in subparagraph (xvii) of Section 1.04(b)
      and within 90 days of the earlier of discovery by the Seller or receipt of
      notice from the applicable Servicer of a breach of such representation and
      warranty by the Seller, which breach materially and adversely affects the
      interests of the Class 2-A4, Class 2-A5, Class 3-A2, Class 3-A3 and Class 4-A2
      Certificateholders in respect of any Prepayment Charge, the Seller shall, if
      (i)
      such representation and warranty is breached and a Principal Prepayment has
      occurred or (ii) if a change in law subsequent to the Closing Date, as
      applicable, limits the enforceability of the Prepayment Charge (other than
      in
      the circumstances set forth in subparagraph (xvii) of Section 1.04(b)), pay,
      at
      the time of such Principal Prepayment or change in law, the amount of the
      scheduled Prepayment Charge, for the benefit of the holders of the Class 2-A4,
      Class 2-A5, Class 3-A2, Class 3-A3 and Class 4-A2 Certificates, by depositing
      such amount into the Certificate Account no later than the Deposit Date
      immediately following the Prepayment Period in which such Principal Prepayment
      on the related Mortgage Loan or such change in law has occurred, net of any
      Servicer Prepayment Charge Payment Amount made by the applicable Servicer with
      respect to the related Mortgage Loan in lieu of collection of such Prepayment
      Charge.
    Section
      1.05. Grant
      Clause.
    It
      is
      intended that the conveyance of the
      Seller’s
      right,
      title and interest in and to the Mortgage Loans and other property conveyed
      pursuant to this Agreement on the Closing Date shall constitute, and shall
      be
      construed as, a sale of such property and not a grant of a security interest
      to
      secure a loan. However, if any such conveyance is deemed to be in respect of
      a
      loan, it is intended that: (1) the rights and obligations of the parties shall
      be established pursuant to the terms of this Agreement; (2) the
      Seller
      hereby
      grants to the Depositor a first priority security interest to secure payment
      of
      an obligation in an amount equal to the purchase price set forth in Section
      1.01(a) in all of the
      Seller’s
      right,
      title and interest in, to and under, whether now owned or hereafter acquired,
      the Mortgage Loans and other property; and (3) this Agreement shall constitute
      a
      security agreement under applicable law. 
    15
        Section
      1.06. Assignment
      by Depositor.
    Concurrently
      with the execution of this Agreement, the Depositor shall assign its interest
      under this Agreement with respect to the Mortgage Loans to the Trustee, and
      the
      Trustee then shall succeed to all rights of the Depositor under this Agreement.
      All references to the rights of the Depositor in this Agreement shall be deemed
      to be for the benefit of and exercisable by its assignee or designee,
      specifically including the Trustee.
    ARTICLE
      II.
    MISCELLANEOUS
      PROVISIONS
    Section
      2.01. Binding
      Nature of Agreement; Assignment.
    This
      Agreement shall be binding upon and inure to the benefit of the parties hereto
      and their respective successors and permitted assigns.
    Section
      2.02. Entire
      Agreement.
    This
      Agreement contains the entire agreement and understanding among the parties
      hereto with respect to the subject matter hereof, and supersedes all prior
      and
      contemporaneous agreements, understandings, inducements and conditions, express
      or implied, oral or written, of any nature whatsoever with respect to the
      subject matter hereof. The express terms hereof control and supersede any course
      of performance and/or usage of the trade inconsistent with any of the terms
      hereof.
    Section
      2.03. Amendment.
    (a) This
      Agreement may be amended from time to time by the
      Seller
      and the
      Depositor, with the consent of the Trustee but without notice to or the consent
      of any of the Certificateholders, (i) to cure any ambiguity, (ii) to cause
      the
      provisions herein to conform to or be consistent with or in furtherance of
      the
      statements made with respect to the Certificates, the Trust Fund, the Trust
      Agreement or this Agreement in the Prospectus Supplement; or to correct or
      supplement any provision herein which may be inconsistent with any other
      provisions herein, (iii) to make any other provisions with respect to matters
      or
      questions arising under this Agreement or (iv) to add, delete, or amend any
      provisions to the extent necessary or desirable to comply with any requirements
      imposed by the Code and the REMIC Provisions. No such amendment effected
      pursuant to clause (iii) of the preceding sentence shall adversely affect in
      any
      material respect the interests of any Certificateholder. Any such amendment
      shall be deemed not to adversely affect in any material respect any
      Certificateholder if the Trustee receives written confirmation from each Rating
      Agency that such amendment will not cause such Rating Agency to reduce the
      then
      current rating assigned to the Certificates, if any (and any Opinion of Counsel
      requested by the Trustee in connection with any such amendment may rely
      expressly on such confirmation as the basis therefor).
    (b) This
      Agreement may also be amended from time to time by the Seller and the Depositor
      with the consent of the Trustee and the Certificateholders of not less than
      66-2/3% of the Class Principal Amount or Class Notional Amount (or Percentage
      Interest) of each Class of Certificates affected thereby for the purpose of
      adding any provisions to or changing in any manner or eliminating any of the
      provisions of this Agreement or of modifying in any manner the rights of the
      Certificateholders; provided,
      however,
      that no
      such amendment may (i) reduce in any manner the amount of, or delay the timing
      of, payments received on Mortgage Loans which are required to be distributed
      on
      any Certificate without the consent of the Certificateholder of such Certificate
      or (ii) reduce the aforesaid percentages of Class Principal Amount or Class
      Notional Amount (or Percentage Interest) of Certificates of each Class, the
      Certificateholders of which are required to consent to any such amendment
      without the consent of the Certificateholders of 100% of the Class Principal
      Amount or Class Notional Amount (or Percentage Interest) of each Class of
      Certificates affected thereby. For purposes of this paragraph, references to
      “Certificateholder” or “Certificateholders” shall be deemed to include, in the
      case of any Class of Book-Entry Certificates, the related Certificates
      Owners.
    16
        (c) It
      shall
      not be necessary for the consent of Certificateholders under this Section 2.03
      to approve the particular form of any proposed amendment, but it shall be
      sufficient if such consent shall approve the substance thereof. The manner
      of
      obtaining such consents and of evidencing the authorization of the execution
      thereof by Certificateholders shall be subject to such reasonable regulations
      as
      the Trustee may prescribe.
    Section
      2.04. Governing
      Law.
    THIS
      AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF
      THE
      STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS (OTHER
      THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW), AND THE OBLIGATIONS, RIGHTS
      AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH
      SUCH LAWS.
    Section
      2.05. Severability
      of Provisions.
    If
      any
      one or more of the covenants, agreements, provisions or terms of this Agreement
      shall be for any reason whatsoever held invalid, then such covenants,
      agreements, provisions or terms shall be deemed severable from the remaining
      covenants, agreements, provisions or terms of this Agreement and shall in no
      way
      affect the validity or enforceability of the other provisions of this
      Agreement.
    Section
      2.06. Indulgences;
      No Waivers.
    Neither
      the failure nor any delay on the part of a party to exercise any right, remedy,
      power or privilege under this Agreement shall operate as a waiver thereof,
      nor
      shall any single or partial exercise of any right, remedy, power or privilege
      preclude any other or further exercise of the same or of any other right,
      remedy, power or privilege, nor shall any waiver of any right, remedy, power
      or
      privilege with respect to any occurrence be construed as a waiver of such right,
      remedy, power or privilege with respect to any other occurrence. No waiver
      shall
      be effective unless it is in writing and is signed by the party asserted to
      have
      granted such waiver, as well as the Trustee.
    17
        Section
      2.07. Headings
      Not to Affect Interpretation.
    The
      headings contained in this Agreement are for convenience of reference only,
      and
      they shall not be used in the interpretation hereof.
    Section
      2.08. Benefits
      of Agreement.
    The
      parties to this Agreement agree that it is appropriate, in furtherance of the
      intent of such parties set forth herein, that the Trustee enjoys the full
      benefit of the provisions of this Agreement each as an intended third party
      beneficiary; provided,
      however,
      nothing
      in this Agreement, express or implied, shall give to any Person, other than
      the
      parties to this Agreement and their successors hereunder, the Trustee and the
      Certificateholders, any benefit or legal or equitable right, power, remedy
      or
      claim under this Agreement.
    Section
      2.09. Counterparts.
    This
      Agreement may be executed in one or more counterparts, each of which shall
      be
      deemed to be an original, and all of which together shall constitute one and
      the
      same instrument.

        IN
      WITNESS WHEREOF, the Seller and the Depositor have caused their names to be
      signed hereto by their respective duly authorized officers as of the date first
