      No
      consent, approval, authorization or order of any court, regulatory body or
      governmental agency or body is required for the execution, delivery and
      performance by Seller of, or compliance by the Seller with this Agreement,
      the
      sale of the Mortgage Loans or the consummation of the transactions contemplated

      Neither the execution and delivery of this Agreement, the sale of the Mortgage
      Loans to Purchaser, the consummation of any other transaction contemplated
      herein, nor the fulfillment of or compliance with the terms of this Agreement,
      will conflict with or result in the breach of any term or provision of the

      in a
      material breach, violation or acceleration of or constitute a material default
      under, the terms of any indenture or other agreement or instrument to which
      Seller is a party or by which it is bound, or any statute, order, judgment,
      governmental rule or regulation applicable to Seller or any of its properties;
      
8
        (iv)
      Seller is not aware of any facts or circumstances which will materially impair
      its ability to perform its obligations under this Agreement;
    (v)
      There
      is no action, suit, proceeding or investigation pending or, to Seller’s
      knowledge, threatened, that, if determined adversely to Seller, would materially

      Agreement on the Sale Date, the execution, delivery or enforceability of this
      Agreement, or the ability of Seller to perform its obligations hereunder or
      which would have a material adverse effect on the financial condition of
      Seller;
    (vi)
      No
      consent, approval, authorization or order of any court, regulatory body or
      governmental agency or body is required for the execution, delivery and
      performance by Seller of or compliance by Seller with this Agreement, the sale
      of the Mortgage Loans or the consummation of the transactions contemplated
      by
      this Agreement;
    (vii)
      With respect to each Mortgage Loan:
    (a) The
      information with respect to such Mortgage Loan set forth on the Mortgage Loan
      Schedule is complete, true and correct. 
    (b) The
      Mortgage and the Mortgage Note is not assigned or pledged to any Person and,
      immediately prior to the transfer thereof to the Purchaser pursuant to
Section 2.1,
      the
      Seller had good and marketable title thereto. The Seller is the sole owner
      and
      holder of such Mortgage Loan free and clear of any and all liens, claims,
      encumbrances, participation interests, equities, pledges, charges, or security
      interests of any nature and has full right and authority, subject to no interest
      or participation of, or agreement with, any other party, to sell and assign
      such
      Mortgage Loan pursuant to this Agreement. Upon the transfer thereof to the
      Purchaser pursuant to Section 2.1,
      the
      Seller will have taken all actions necessary on its part to be taken so that
      the
      Purchaser will have good indefeasible title to, and will be sole owner of,
      the
      Mortgage and the Mortgage Note, free and clear of any and all liens, claims,
      encumbrances, participation interests, equities, pledges, charges, or security
      interests of any nature.
    (c) With
      respect to each Mortgage Loan (other than a Cooperative Loan), (i) the Mortgage
      is a valid, subsisting and enforceable first lien on the Mortgaged Property,
      including all buildings, fixtures, installations and improvements to the
      Mortgaged Property, and the Mortgaged Property is free and clear of all
      encumbrances and liens having parity with or priority over the first lien of
      the
      Mortgage except for (A) the lien of current real property taxes and
      assessments not yet due and payable, (B) covenants, conditions and
      restrictions, rights of way, easements, mineral right reservations and other
      matters of public record as of the date of recording of such Mortgage, such
      exceptions generally being acceptable under prudent mortgage lending standards
      and specifically reflected in the appraisal made in connection with the
      origination of such Mortgage Loan or specifically referred to in the mortgagee’s
      policy of title insurance and (C) other matters to which like properties
      are commonly subject that do not materially interfere with the value (as
      determined by the Appraised Value), use, enjoyment or marketability of the
      Mortgaged Property and (ii) there are no security agreements, pledged accounts,
      chattel mortgages, or equivalent documents related to the Mortgage.
9
        (d) The
      terms
      of the Mortgage and the Mortgage Note 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 interest of the Purchaser, each of which
      is a part of the Mortgage File and which has been delivered to the Custodian.
      The substance of any such alteration or modification is reflected on the
      Mortgage Loan Schedule and has been approved by the issuer of any Primary
      Mortgage Insurance Policy.
    (e) No
      instrument of release, waiver, alteration, or modification has been executed
      in
      connection with such Mortgage Loan, and no Mortgagor has been released, in
      whole
      or in part, except in connection with an assumption agreement, which is part
      of
      the Mortgage File and has been delivered to the Custodian, and the terms of
      which are reflected in the Mortgage Loan Schedule and has been approved by
      the
      issuer of any Primary Mortgage Insurance Policy.
    (f) 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
      such a default, breach, violation, or event of acceleration, and neither the
      Seller, nor to the best of the Seller’s knowledge, any prior seller or servicer,
      has waived any such default, breach, violation, or event of acceleration.
      All taxes,
      governmental assessments (including assessments payable in future installments),
      insurance premiums, leasehold payments, or ground rents which previously became
      due and owing in respect of or affecting the related Mortgaged Property have
      been paid, or an escrow of funds has been established in an amount sufficient
      to
      pay for every such item which remains unpaid and which has been assessed but
      is
      not yet due and payable. The Seller has not advanced funds, or induced,
      solicited, or knowingly received any advance of funds by a party other than
      the
      Mortgagor, directly or indirectly, for the payment of any amount required by
      the
      Mortgage or the Mortgage Note. No foreclosure action has been commenced with
      respect to such Mortgage Loan.
    (g) The
      Mortgaged Property is free of material damage or waste and in good repair.
      There
      is no proceeding pending or, to the best of the Seller’s knowledge, threatened
      for the total or partial condemnation of the Mortgaged Property and no notice
      of
      any such pending or threatened proceeding has been received so as to adversely
      impair the value or marketability of the Mortgaged Property.
    (h) 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 law could give rise to
      such lien) which are, or may be, liens prior or equal to the lien of the related
      Mortgage, which are not insured against by the related mortgagee’s policy of
      title insurance.
    (i) All
      of
      the improvements which were included for the purpose of determining the
      Appraised Value of the Mortgaged Property were completed at the time that such
      Mortgage Loan was originated and lie wholly within the boundaries and building
      restriction lines of such Mortgaged Property. 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, subdivision law or ordinance.
    10
          (j) The
      Seller is (or, if the Seller did not originate the Mortgage Loan, the
      originator, during the period in which it held and disposed of such interest,
      was): (i) in compliance with any and all applicable licensing requirements
      of the laws of the state wherein the Mortgaged Property is located and
      (ii)(A) organized under the laws of such state, (B) qualified to do
      business in such state, (C) a federal savings and loan association or
      national bank having principal offices in such state, (D) not doing
      business in such state, or (E) not required to qualify to do business in
      such state.
    (k) No
      Monthly Payment with respect to such Mortgage Loan is delinquent as of the
      related Sale Date. For purposes of the prior sentence, “delinquent” means that a
      scheduled Monthly Payment was not received by the time the next Monthly Payment
      was due and such scheduled Monthly Payment remains unpaid. All payments required
      to be made under the related Mortgage and Mortgage Note through and including
      the Cut-Off Date, have been made. Not more than one payment required to be
      made
      under the related Mortgage and Mortgage Note has remained unpaid through its
      next Due Date (excluding any applicable grace period) during the twelve months
      immediately preceding the Cut-Off Date.
    (l) There
      are
      no custodial agreements in effect adversely affecting the right or ability
      of
      the Seller to make the deliveries specified in Section
      2.2.
      Each of
      the documents with respect to such Mortgage Loan specified in Section 2.2,
      in
Exhibit A hereto
      or
      in the Mortgage File, is genuine, true, correct and complete and has not been
      altered or modified in any way except as noted in the Mortgage File, and each
      is
      duly executed and in due and proper form. Each of the documents with respect
      to
      such Mortgage Loan specified in Exhibit A
      hereto
      is genuine, true, correct and complete and has not been altered or modified
      in
      any way except as reflected on the Mortgage Loan Schedule.
    (m) The
      Mortgage Note and the Mortgage are genuine, and each is the legal, valid and
      binding obligation of the maker thereof and each party assuming liability
      therefor, enforceable in accordance with its terms, except as such enforcement
      may be limited by bankruptcy, insolvency, reorganization, moratorium, or other
      similar laws affecting the enforcement of creditors’ rights generally and except
      that the equitable remedy of specific performance and other equitable remedies
      are subject to the discretion of the courts. All parties to the Mortgage Note
      and the Mortgage had legal capacity to execute the Mortgage Note and the
      Mortgage and convey the estate therein purported to be conveyed, and the
      Mortgage Note and the Mortgage have been duly and properly executed by such
      parties or pursuant to a valid power-of-attorney that has been recorded with
      the
      Mortgage. 
    (n) The
      transfer of the Mortgage Note and the Mortgage as and in the manner contemplated
      by this Agreement is sufficient fully to transfer to the Purchaser all right,
      title and interest of the Seller thereto as note holder and mortgagee or trust
      deed beneficiary. The Mortgage has been duly assigned and the Mortgage Note
      has
      been duly endorsed as provided in Section 2.2.
      The
      Assignment of Mortgage delivered to the Purchaser pursuant to Section 2.2
      is in
      recordable form except for the insertion of the name of the assignee and
      recording information and is acceptable for recording under the laws of the
      applicable jurisdiction.
11
        (o) Any
      and
      all requirements of any federal, state, or local law including, without
      limitation, usury, predatory and abusive lending, truth-in-lending, real estate
      settlement procedures, consumer credit protection, equal credit opportunity,
      or
      disclosure laws applicable to such Mortgage Loan have been complied with, and
      the Seller shall maintain, in its possession, available for the Purchaser’s
      inspection, and shall deliver to the Purchaser or its designee upon demand,
      evidence of compliance with all such requirements. The consummation of the
      transactions contemplated by this Agreement will not cause the violation of
      any
      such laws.
    (p) The
      proceeds of such Mortgage Loan have been fully disbursed. There is no
      requirement for, and the Seller shall not make any, future advances under the
      terms of the Mortgage Loan. Any future advances made prior to the applicable
      Cut-off Date have been consolidated with the principal balance secured by the
      Mortgage, and such principal balance, as consolidated, bears a single interest
      rate and single repayment term reflected on the related Mortgage Loan Schedule.
      Unless such Mortgage Loan is subject to negative amortization, the Unpaid
      Principal Balance as of the applicable Cut-off Date does not exceed the original
      principal amount of such Mortgage Loan. 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, and certificates of completion with respect
      thereto are contained in the related credit file. All costs, fees and expenses
      incurred in making, or closing or recording such Mortgage Loan have been paid
      or
      will be paid in the ordinary course of business.
    (q) Such
      Mortgage Loan (unless it is a Cooperative Loan) is covered by an ALTA mortgage
      title insurance policy acceptable to Seller, with, in the case of an Adjustable
      Rate Mortgage Loan, an adjustable rate mortgage endorsement, substantially
      in
      the form of ALTA Form 6.1 or 6.2, or such other generally used and acceptable
      form of policy and applicable endorsements acceptable to FNMA or FHLMC. Each
      such policy affirmatively insures ingress and egress and insures against
      encroachments by or upon the Mortgaged Property. Each such policy was issued
      on
      the date of the origination of each related Mortgaged Loan by a title insurer
      acceptable under Seller’s underwriting guidelines and qualified to do business
      in the jurisdiction where the Mortgaged Property is located, insuring the
      Seller, and its successors and assigns, as to the first priority lien of the
      Mortgage in the original principal amount of such Mortgage Loan. Each such
      policy has been duly and validly endorsed to the Purchaser or the assignment
      to
      the Purchaser of the Seller’s interest does not require the consent of or
      notification to the insurer, and such mortgage title insurance policy is in
      full
      force and effect. Where required by law or regulation, the Mortgagor has been
      given the opportunity to choose the carrier of the required mortgage title
      insurance. No claims have been made under such policy and the Seller has taken
      no action that would impair the enforceability of such policy. 
    (r) Unless
      such Mortgage Loan is a Cooperative Loan, all buildings and other improvements
      upon the Mortgaged Property are insured against loss by fire, hazards of
      extended coverage and such other hazards as are customary in the area where
      the
      Mortgaged Property is located, pursuant to insurance policies conforming to
      the
      requirements of Section 2.13 of the Servicing Agreement and issued by an
      insurer acceptable to FNMA or FHLMC. If the Mortgaged Property is in an area
      then identified on a flood hazard boundary map or flood insurance rate map
      issued by the Federal Emergency Management Agency as having special flood
      hazards (and such flood insurance is available), a flood insurance policy is
      in
      effect meeting the requirements of the current guidelines of the Federal
      Insurance Administration with an insurance carrier acceptable to Seller. Each
      individual insurance policy has been validly issued and is in full force and
      effect. The Seller has caused to be performed all acts required to preserve
      the
      rights and interests of the Purchaser in all insurance policies required by
      this
      Agreement, including, without limitation, notification of insurers, and
      assignment of policies or interests therein. Each individual insurance policy
      contains a standard mortgagee clause naming the Seller, and its successors
      and
      assigns, as mortgagee and loss payee. All premiums due thereon have been paid.
      The Mortgage obligates the Mortgagor to maintain all such insurance at the
      Mortgagor’s cost and expense, and upon the Mortgagor’s failure to do so,
      authorizes the servicer or the owner of the Mortgage to obtain and maintain
      such
      insurance at the Mortgagor’s cost and expense and to seek reimbursement therefor
      from the Mortgagor. No claims have been made under such policies since
      origination of the Mortgage Loan, and the Seller has taken no action that would
      impair the coverage of any such insurance policy, the benefits of any
      endorsement or the validity, binding effect and enforceability of the
      foregoing.
    12
          (s) There
      is
      no valid offset, defense, counterclaim or right of rescission as to the related
      Mortgage Note or Mortgage, including the obligation of the Mortgagor to pay
      the
      unpaid principal of or interest on such Mortgage Note. The operation of any
      of
      the terms of such Mortgage Note or Mortgage, or the exercise of any right
      thereunder, will not render either the Mortgage Note or the Mortgage
      unenforceable, in whole or in part, or subject to any right of rescission,
      set-off, recoupment, counterclaim or defense, including, without limitation,
      the
      defense of usury, and no such right of rescission, set-off, recoupment,
      counterclaim or defense has been asserted with respect thereto. Such Mortgage
      Loan is not subject to any pending bankruptcy, insolvency, reorganization or
      moratorium. If such Mortgage Loan is an Adjustable Rate Mortgage Loan, all
      the
      applicable terms of the Mortgage Note pertaining to adjustments of the Mortgage
      Interest Rate and the Monthly Payments and payment adjustments in connection
      therewith are enforceable and will not affect the priority of the Mortgage
      lien.
      If such Mortgage Loan is an Adjustable Rate Mortgage Loan, the related Mortgage
      Note has been timely and appropriately adjusted, if such adjustment is required,
      and the respective Mortgagor timely and appropriately advised. All such
      adjustments have been made in compliance with applicable law and in accordance
      with the terms of the Mortgage Loan documents.
    (t) Such
      Mortgage Loan was originated by (i)  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
      (ii) a mortgage banker approved by the Secretary of Housing and Urban
      Development. 
    (u) Principal
      payments on such Mortgage Loan commenced or are required to commence no more
      than two months after funds were disbursed in connection with such Mortgage
      Loan. Unless such Mortgage Loan is subject to negative amortization as indicated
      on the Mortgage Loan Schedule, the Mortgage Note requires a Monthly Payment
      which is sufficient to fully amortize the original principal balance over the
      remaining term thereof and to pay interest at the Mortgage Interest
      Rate.
    13
          (v) Such
      Mortgage Loan is a residential mortgage loan having an original term to maturity
      as set forth on the Mortgage Loan Schedule, and if no such term is specified
      in
      the Mortgage Loan Schedule, the term to maturity does not exceed forty years,
      with interest payable in arrears on the first day of each month (or such other
      day of the month as may be noted on the Mortgage Loan Schedule). On the related
      Sale Date, and if such Mortgage Loan is an Adjustable Rate Mortgage Loan, until
      the next Interest Rate Adjustment Date, the Mortgage Interest Rate is as set
      forth on the Mortgage Loan Schedule. If such Mortgage Loan is an Adjustable
      Rate
      Mortgage Loan, the Mortgage Interest Rate is subject to adjustment periodically
      on each Interest Rate Adjustment Date to a new Mortgage Interest Rate (rounded
      as provided in the Mortgage Note) equal to the then current Index plus the
      Gross
      Margin as specified on the related Mortgage Note, subject to the Maximum
      Mortgage Interest Rate, the Minimum Mortgage Interest Rate, the Interest Rate
      Increase Maximum and the Interest Rate Decrease Maximum, in each case if and
      to
      the extent specified in the Mortgage Loan Schedule.
    (w) The
      Mortgage Note is not and has not been secured by any collateral, pledged account
      or other security, except the lien of the Mortgage or the Security Agreement,
      as
      applicable.
    (x) The
      Mortgage contains customary and enforceable provisions which render the rights
      and remedies of the Purchaser thereof adequate for the realization against
      the
      Mortgaged Property of the benefits of the security, including (i) in the
      case of a Mortgage designated as a deed of trust, by trustee’s sale, and
      (ii) otherwise by judicial foreclosure. There is no homestead, dower,
      curtesy 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. The Mortgage or Mortgage
      Note contains a provision that is, to the extent not prohibited by federal
      or
      state law, enforceable and that provides for the acceleration of the payment
      of
      the unpaid principal balance of the Mortgage Loan in the event that the
      Mortgaged Property is sold or transferred without the prior written consent
      of
      the mortgagee thereunder. The Mortgagor has not notified the Seller and the
      Seller has no knowledge of any relief requested or allowed to the Mortgagor
      under the Servicemembers Civil Relief Act or any comparable state
      legislation.
    (y) If
      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 such Mortgage, and no fees or expenses are or will become payable
      by
      the Purchaser to the trustee under the deed of trust, except in connection
      with
      a trustee’s sale after default by the Mortgagor.
    (z) The
      Mortgaged Property consists of (x) a single parcel of real property
      separately assessed for tax purposes, upon which is erected a detached or an
      attached one-to-four-family residence, an individual condominium or an
      individual unit in a planned unit development or (y) in the case of a
      Cooperative Loan, the related Coop Ownership Interests, in each case that is
      in
      compliance with Seller’s applicable requirements. Such Mortgaged Property is not
      (i) a property held in trust (other than a revocable inter vivos trust that
      is in compliance with FNMA’s requirements applicable to Seller, or, if the
      Mortgaged Property is located in Illinois, an Illinois land trust), (ii) a
      mobile home or manufactured home, or (iii) a recreational vehicle. Such
      Mortgage Loan is not considered an agricultural loan. The related Mortgaged
      Property does not consist of a log home, earthen home, underground home or
      a
      home which is situated on more than twenty acres of property. No portion of
      the
      related Mortgaged Property is being used for commercial
      purposes.
14
        (aa) The
      Loan-to-Value Ratio of such Mortgage Loan at the time of origination was not
      greater than the Loan to Value Ratio set forth in the Mortgage Loan Schedule,
      and if no such percentage is specified, not greater than 95%. If such Mortgage
      Loan had at the time of origination a Loan-to-Value Ratio in excess of 80%,
      such
      Mortgage Loan is subject to a Primary Mortgage Insurance Policy. All provisions
      of such Primary Mortgage 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. No Mortgage Loan requires payment of such premiums, in whole or
      in
      part, by the Purchaser. No action has been taken and no event has occurred
      that
      has, or will result in the exclusion from, denial of, or defense to coverage.
      Any Mortgage Loan subject to a Primary Mortgage Insurance Policy obligates
      the
      Mortgagor to maintain the Primary Mortgage Insurance Policy and to pay all
      related premiums and charges. The mortgage interest rate for the Mortgage Loan
      as set forth on the Mortgage Loan Schedule is net of any such insurance premium.
      None of the Mortgage Loans are covered by a “lender-paid” Primary Mortgage
      Insurance Policy.
    (bb) Such
      Mortgage Loan was underwritten in accordance with the underwriting guidelines
      of
      the Seller or the originator of the Mortgage Loan in effect at the time such
      Mortgage Loan was originated, which underwriting guidelines have been provided
      to the Purchaser.
    (cc) There
      exist no deficiencies in excess of $1,000 with respect to escrow deposits and
      payments, if such are required, for which customary arrangements for repayment
      thereof have not been made or which the Seller expects not to be cured, and
      no
      escrow deposits or payments of other charges or payments due the Seller have
      been capitalized under the Mortgage or the Mortgage Note.
    (dd) Such
      Mortgage Loan does not have a shared appreciation feature or other contingent
      interest feature, and such Mortgage Loan does not involve buydowns, balloons,
      timeshares or graduated payments. If such Mortgage Loan is an Adjustable Rate
      Mortgage Loan, it is not convertible to a Mortgage Loan with a fixed Mortgage
      Interest Rate, unless otherwise indicated in the related Mortgage Loan Schedule.
      
    (ee) The
      origination, servicing and collection practices used with respect to such
      Mortgage Loan (including without limitation, the establishment, maintenance
      and
      servicing of the Escrow Accounts, if any), have been in all material respects
      in
      accordance with applicable laws and regulations, the terms of the Mortgage
      Loan
      documents, and Acceptable Servicing Procedures. With respect to Escrow Accounts
      and Escrow Payments that the Seller is entitled to collect, there are no
      deficiencies for which customary arrangements for repayment have not been made.
      All Escrow Payments have been collected in all material respects in compliance
      with applicable law, Acceptable Servicing Procedures and the provisions of
      the
      Mortgage Loan documents. If such Mortgage Loan is the subject of an escrow,
      escrow of funds is not prohibited by applicable law and has been established
      in
      an amount sufficient to pay for every escrowed item that remains unpaid and
      has
      been assessed but is not yet due and payable. Any Escrow Account interest
      required to be paid pursuant to applicable law has been properly paid and
      credited.
15
        (ff) If
      such
      Mortgage Loan is an Adjustable Rate Mortgage Loan, the Mortgagor has received
      and has executed, where applicable, prior to origination of the Mortgage Loan,
      any disclosure and rescission materials required by applicable law with respect
      to the making of the Mortgage Loan.
    (gg) The
      appraisal report with respect to the Mortgaged Property contained in the credit
      file was signed by a qualified appraiser, who met the requirements of the
      Seller’s appraisal policies and procedures, 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 such
      application and who otherwise meets the requirements of Seller. Such appraisal
      was made in accordance with the relevant provisions of the Financial
      Institutions Reform, Recovery and Enforcement Act of 1989, as in effect on
      the
      date such Mortgage Loan was originated, and on forms that contain no less
      information than contained in a FNMA Form 1004 appraisal. 
    (hh) No
      Mortgage Loan is subject to the Home Ownership and Equity Protection Act of
      1994
      or Section 226.32 of Regulation Z, is a “high-cost” loan or a “predatory” loan
      as defined under any state or local law or regulation applicable to the
      originator of such Mortgage Loan or which would result in liability to the
      purchaser or assignee of such Mortgage Loan under any predatory or abusive
      lending law, or, without limiting the generality of the foregoing, is a
“covered” loan under the laws of the states of California, Colorado or
      Ohio.
    (ii) Unless
      otherwise stated in the Mortgage Loan Schedule, if such Mortgage Loan is an
      Adjustable Rate Mortgage Loan, it does not have an interest rate step-down
      feature or similar feature that would result in a downwards adjustment to the
      Mortgage Interest Rate, the Gross Margin or the Index as a result of the related
      Mortgagor’s payment method or payment history (e.g., no downwards adjustment in
      return for allowing the automatic withdrawal of funds from the related
      Mortgagor’s bank account to make the Monthly Payments on such Mortgage Loan, or
      for making payments when due on such Mortgage Loan). 
    (jj) No
      misrepresentation, negligence or fraud has taken place on the part of the Seller
      or any third party originator of such Mortgage Loan and the Seller is not aware
      of any fact that would reasonably lead the Seller to believe that any
      misrepresentation, negligence or fraud has taken place on the part of any other
      Person, including without limitation the Mortgagor, any appraiser, any builder
      or developer, or any other party involved in the origination of the Mortgage
      Loan or in the application of any insurance in relation to such Mortgage
      Loan.
    (kk) The
      Mortgaged Property is lawfully occupied under applicable law; 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.
    16
          (ll) The
      Seller has no knowledge of any circumstances or condition existing as of the
      Sale Date with respect to the Mortgage, the Mortgaged Property, the Mortgagor
      or
      the Mortgagor’s credit standing that can reasonably be expected to cause the
      Mortgage Loan to be an unacceptable investment as of the Sale Date.
    (mm) Neither
      the Seller, nor to the Seller’s knowledge, the related Mortgagor, has received
      any notice that the Mortgaged Property is in violation or potential violation
      of
      an environmental law pertaining to environmental hazards including, without
      limitation, asbestos. To the best of the Seller’s knowledge, the Mortgaged
      Property is in compliance with all applicable environmental law.
    (nn) Such
      Mortgage Loan was selected from among the outstanding mortgage loans of the
      same
      type in the Seller’s portfolio on the Sale Date and such selection was not made
      in a manner so as to affect adversely the interests of the
      Purchaser.
    (oo) Interest
      on each Mortgage Loan is calculated on the basis of a 360-day year consisting
      of
      twelve 30-day months.
    (pp) If
      such
      Mortgage Loan is a Cooperative Loan, the security instruments create a valid,
      enforceable and subsisting first priority security interest in the related
      cooperative shares securing the related cooperative note, subject only to
      (x) the lien of the related cooperative for unpaid assessments representing
      the Mortgagor’s pro rata share of payments for a blanket mortgage, if any,
      current and future real property taxes, insurance premiums, maintenance fees
      and
      other assessments to which like collateral is commonly subject, and (y) other
      matters to which like collateral is commonly subject and which do not materially
      interfere with the benefits of the security intended to be provided; provided,
      however, that the related proprietary lease for the Cooperative Apartment may
      be
      subordinated or otherwise subject to the lien of a mortgage on the cooperative
      building.
    (qq) 
      If such
      Mortgage Loan is a Cooperative Loan, a search for filings of financing
      statements has been made by a party competent to make the same, which party
      is
      acceptable to Seller in accordance with its underwriting guidelines and is
      qualified to do business in the jurisdiction where the cooperative unit is
      located; and such search has not found anything which would materially and
      adversely affect the Cooperative Loan.
    (rr) If
      such
      Mortgage Loan is a Cooperative Loan, the related cooperative corporation that
      owns title to the related cooperative apartment building is a “cooperative
      housing corporation” within the meaning of Section 216 of the Code, and is in
      material compliance with applicable laws which, if not complied with, could
      have
      a material adverse effect on the Mortgaged Property
    (ss) If
      such
      Mortgage Loan is a Cooperative Loan: (i) the terms of the related proprietary
      lease or occupancy agreement is longer than the terms of the Cooperative Loan,
      (ii) there is no provision in such proprietary lease or occupancy agreement
      which requires the Mortgagor to offer for sale the cooperative shares owned
      by
      such Mortgagor first to the Cooperative, and (iii) there is no prohibition
      against pledging the shares of the cooperative corporation or assigning the
      cooperative lease.
    17
          (tt) No
      loan
      is a High Cost Loan or Covered Loan (as such terms are defined in the Standard
      & Poor’s LEVELS® Glossary in effect on the Closing Date).
    (uu) Each
      Mortgage Loan is a “qualified mortgage” within Section 860G(a)(3) of the
      Code.

    Section
      4.2 Remedies.
    It
      is
      understood and agreed that the representations and warranties set forth in
      Section
      4.1
      shall
      survive delivery of the Mortgage Loans to Purchaser and shall inure to the
      benefit of Purchaser notwithstanding any examination of any Mortgage File or
      other documents relating to the Mortgage Loans by Purchaser. Upon discovery
      by
      either Seller or Purchaser of a breach of any of the representations and
      warranties set forth in Section
      4.1,
      the
      party discovering such breach shall give prompt written notice to the other.
      Within 60 days after the earlier of discovery or its receipt of notice of any
      breach of a representation or warranty set forth in Section
      4.1above
      relating to a particular Mortgage Loan which materially and adversely affects
      the value of the Mortgage Loan or Purchaser’s interest therein, Seller shall
      cure such breach in all material respects or shall, at Purchaser’s option,
      repurchase the Mortgage Loan for an amount equal to (i) the unpaid principal
      balance of the Mortgage Loan plus (ii) interest on such unpaid principal balance
      at the applicable Mortgage Interest Rate less the related Servicing Fee from
      the
      date to which interest has last been paid by the Mortgagor to the last day
      of
      the month in which such repurchase occurs plus (iii) with respect to any
      Mortgage Loan subject to a Pass-Through Transfer, any costs and damages (in
      excess of the amounts to be paid pursuant to clauses (i) and (ii) above)
      incurred by the related trust prior to the date of such purchase in connection
      with any violation by such Mortgage Loan of any predatory and abusive lending
      laws, to the extent such costs and damages result from a breach of the
      representation and warranty made by the Seller pursuant to Section
      4.1(vii)(hh).
      Any
      such repurchase shall be accomplished by the deposit by Seller in the account
      designated by Purchaser of the amount of the repurchase price in immediately
      available funds. Within five (5) Business Days after Seller’s deposit of the
      repurchase amount, Purchaser shall cause the Custodian to endorse the applicable
      Mortgage Notes and assign the applicable Mortgages to Seller and promptly
      deliver such instruments, together with all related Mortgage Loan documents,
      to
      Seller.
    Seller
      shall indemnify and hold harmless Purchaser (and its successors and assigns),
      and will reimburse Purchaser (and its successors and assigns), within thirty
      (30) days of receipt of written request, for, all losses, liabilities, damages,
      penalties, fines, forfeitures, deficiencies, claims, judgments or other costs
      or
      expenses incurred by Purchaser (or its successors or assigns), to the extent
      that such loss, damage, deficiency, claim or expense results from any breach
      of
      any representation or warranty made by Seller as set forth in Section
      4.1(vii)
      above.
      The foregoing indemnification shall not, however, cover any indirect, special
      or
      consequential losses, liabilities, damages, penalties, fines, forfeitures,
      deficiencies, claims, judgments or other costs or expenses incurred by Purchaser
      (or its successors or assigns).
    19
          Promptly
      after receipt by the Purchaser of notice of the commencement of any action,
      the
      Purchaser shall, if a claim in respect thereof is to be made against the Seller
      under this Agreement, notify the Seller of the commencement thereof; but the
      omission so to notify the Seller will not relieve Seller of any liability that
      it may have to the Purchaser otherwise than under this Agreement. In case any
      such action is brought against the Purchaser, and it notifies the Seller of
      the
      commencement thereof, the Seller will be entitled to participate therein, and,
      to the extent that it may wish, assume (at its own expense) the defense thereof,
      with counsel reasonably satisfactory to the Purchaser (who shall not, except
      with the written consent of the Purchaser, be counsel to the Seller), and,
      after
      notice from the Seller to the Purchaser under this Section
      4.2,
      the
      Seller shall not be liable for any legal or other expenses subsequently incurred
      by the Purchaser in connection with the defense thereof other than reasonable
      costs of investigation. In no event shall the Seller be liable for the fees
      and
      expenses of more than one counsel for the Purchaser in connection with any
      proceeding in the same jurisdiction. All such fees and expenses shall be
      reimbursed as they are incurred.

      the purchase of the Mortgage Loans or the consummation of the transactions
      contemplated by this Agreement.

      Conflict
      Neither
      the execution and delivery of this Agreement by Purchaser, nor the consummation
      by Purchaser of the transactions hereby contemplated,
      nor compliance with the provisions hereof by Purchaser will conflict with or
      result in a breach of, or constitute a default under, any of the provisions
      of
      Purchaser’s articles of association or by-laws, or any statute, governmental
      rule or regulation, or any judgment, decree or order binding on Purchaser or
      any
      of its properties, or any of the provisions of any contract or other instrument
      to which Purchaser is a party or by which it is bound.
    (d) Compliance
      with Laws.

      is no action, suit, proceeding or investigation pending, or to Purchaser’s
      knowledge, threatened against Purchaser before any court, administrative agency
      or other tribunal (i) asserting the invalidity of this Agreement, (ii) seeking
      to prevent the consummation of any of the transactions contemplated hereby
      or
      (iii) which might materially and adversely affect the performance by Purchaser
      of its obligations under, or the validity or enforceability of, this
      Agreement.
    20
          (e) Performance.
      Purchaser does not believe, nor does it have any reason or cause to believe,

    PASS-THROUGH
      AND WHOLE LOAN TRANSFER; COMPLIANCE WITH REMIC PROVISIONS
    Section
      9.1 Pass-Through Transfers or Whole-Loan Transfers.
    (a) Purchaser
      and Seller agree that with respect to some or all of the Mortgage Loans,
      Purchaser, at its sole option, upon 30 days’ prior written notice to the Seller,
      may effect one or more Whole Loan Transfers or Pass-Through Transfers with
      respect to each Mortgage Loan, retaining Servicer as the servicer or subservicer
      if a master servicer is employed as provided in Section
      9.2;
      provided, however, that Seller’s obligations under Section 9.1(b) with respect
      to any Whole Loan Transfer or Pass-Through Transfer made by Purchaser or any
      of
      its permitted assignees with respect to Mortgage Loans shall cease if, as a
      result thereof, more than four investors would own Mortgage Loans at any one
      time.
    (b) Seller
      shall cooperate with Purchaser in connection with each Whole Loan Transfer
      or
      Pass-Through Transfer permitted under this Section
      9.1.
      In
      connection therewith, Seller shall provide Purchaser with such information
      as it
      customarily provides third parties in connection with Whole Loan Transfers
      or
      Pass-Through Transfers; provided,
      however,
      that
      Seller shall not be obligated to provide any such information unless the
      Mortgage Loans constitute not less than 10% of a single mortgage loan group
      in a
      Pass-Through Transfer. In addition, in connection with each Whole Loan Transfer
      or Pass-Through Transfer permitted hereunder, upon the request of Purchaser,
      Seller shall provide an officer’s certificate to the effect that the
      representations and warranties made by Seller in Section
      4.1
      are true
      and correct as of the date of such certificate, provided that nothing has
      occurred during the period commencing on the Sale Date and ending on the date
      of
      such certificate which would make such representations and warranties untrue.
      Purchaser shall provide Seller with all drafts of the applicable prospectus
      supplement or other similar instrument when produced and shall revise the
      seller’s information contained therein (the “Seller’s Information”) in
      accordance with Seller’s comments to correct any information therein at
      Purchaser’s cost. Notwithstanding anything herein to the contrary, Purchaser
      shall reimburse Seller for all reasonable out-of-pocket expenses, including
      attorney’s fees, incurred by Seller in connection with any Whole Loan Transfer
      or Pass-Through Transfer. 
    (c) Seller
      (i) will indemnify and hold harmless the Purchaser and each Person, if any
      who
      controls Purchaser within the meaning of the Securities Act of 1933, as amended
      (an “Indemnified Party”), against any losses, claims, damages or liabilities to
      which such Indemnified Party may become subject, under the Securities Act of
      1933, as amended, or otherwise, insofar as such losses, claims, damages or
      liabilities (or actions in respect thereof) arise out of or are based upon
      any
      untrue statement of any material fact contained in the Seller’s Information
      included in the prospectus or the prospectus supplement or the disclosure
      document prepared in connection with any permitted Pass-Through Transfer
      (collectively, the “Disclosure Documents”) and (ii) will reimburse each
      Indemnified Party for any legal or other expenses reasonably incurred by such
      Indemnified Party in connection with investigating or defending any such loss,
      claim, damage, liability or action; provided,
      however,
      that
      Seller shall have no such indemnification or reimbursement obligations unless
      the Mortgage Loans constitute not less than 10% of a single mortgage loan group
      in such Pass-Through Transfer. Subject to the foregoing proviso, Seller agrees
      to execute an indemnification agreement in connection with any Pass-Through
      Transfer containing the foregoing indemnity.
23
        (d) Purchaser
      (i) will indemnify and hold harmless Seller against any losses, claims, damages
      or liabilities to which Seller may become subject, under the Securities Act
      of
      1933, as amended, or otherwise, insofar as such losses, claims, damages or
      liabilities (or actions in respect thereof) (x) arise out of or are based upon
      any untrue statement of any material fact contained in any Disclosure Document
      (other than an untrue statement of material fact contained in the Seller’s
      Information), or (y) arise out of or are based upon the omission to state in
      any
      Disclosure Document a material fact required to be stated therein or necessary
      to make the statements therein, in the light of the circumstances under which
      they were made, not misleading (unless such omission constitutes Seller’s
      Information) and (ii) will reimburse Seller for any legal or other expenses
      reasonably incurred by Seller in connection with investigating or defending
      any
      such loss, claim, damage, liability or action. Purchaser agrees to execute
      an
      indemnification agreement containing the foregoing indemnity.
