      Pooling and Servicing Agreement, is dated and effective as of February 1, 2007,
      among CITIGROUP MORTGAGE LOAN TRUST INC., as Depositor, CITIMORTGAGE, INC.,
      as
      Master Servicer and Trust Administrator, CITIBANK, N.A. as Paying Agent,
      Certificate Registrar and Authenticating Agent and U.S. BANK NATIONAL
      ASSOCIATION, as Trustee.

     

    PRELIMINARY
      STATEMENT:

     

    The
      Depositor intends to sell pass-through certificates to be issued hereunder
      in
      multiple classes, which in the aggregate will evidence the entire beneficial
      ownership interest in each REMIC (as defined herein) created hereunder. The
      Trust Fund will consist of a segregated pool of assets comprised of the Mortgage
      Loans and certain other related assets subject to this Agreement.

     

    REMIC
      I-A

     

    As
      provided herein, the Trust Administrator will elect to treat the segregated
      pool
      of assets consisting of the Group 1 Mortgage Loans and certain other related
      assets subject to this Agreement as a REMIC (as defined herein) for federal
      income tax purposes, and such segregated pool of assets will be designated
      as
“REMIC I-A”. The Class R-IA Residual Interest will be the sole class of
“residual interests” in REMIC I-A for purposes of the REMIC Provisions (as
      defined herein). The following table irrevocably sets forth the designation,
      the
      REMIC I-A Remittance Rate, the initial Uncertificated Balance and, for purposes
      of satisfying Treasury regulation Section 1.860G-1(a)(4)(iii), the “latest
      possible maturity date” for each of the REMIC I-A Regular Interests (as defined
      herein). None of the REMIC I-A Regular Interests will be
      certificated.

      Section 11.01. The Trustee and the Trust Administrator may conclusively rely
      upon a certificate of the Depositor or the Master Servicer in determining
      whether a Certificate is held by an Affiliate thereof. All references herein
      to
“Holders” or “Certificateholders” shall reflect the rights of Certificate Owners

    “Certificate
      Owner”: With respect to a Book-Entry Certificate, the Person who is the
      beneficial owner of such Certificate as reflected on the books of the Depository

      agent.

     

    “Certificate
      Principal Balance”: With respect to any Certificate (other than an Interest Only

      of such Certificate on the Distribution Date immediately prior to such date
      of
      determination plus any Subsequent Recoveries added to the Certificate Principal
      Balance of such Certificate pursuant to Section 4.01, reduced by the aggregate
      of (a) all distributions of principal made thereon on such immediately prior
      Distribution Date and (b) without duplication of amounts described in clause
      (a)

      Certificate multiplied by the excess, if any, of (A) the then aggregate Stated
      Principal Balance of the Mortgage Loans in such related Collateral Pool over
      (B)
      the then aggregate Certificate Principal Balances of all other Classes of
      Certificates (other than any Class of Interest Only Certificates) relating

    provided,
      however, no reduction to the Group 1 Senior Prepayment Percentage
      described above shall be made as of any Distribution Date unless (i) the
      outstanding principal balance of the Group 1 Mortgage Loans delinquent 60 days
      or more (including REO Properties and Mortgage Loans in foreclosure) averaged
      over the last six months (or such fewer number of months as have elapsed from
      the Cut-Off Date through the end of the related Prepayment Period) does not
      exceed 50% of the sum of the then current Certificate Principal Balances of
      the
      Group 1 Subordinate Certificates and (ii) Realized Losses on the Group 1
      Mortgage Loans to date are less than the then applicable Trigger
      Amount.

     

    On
      any
      Distribution Date on which Realized Losses on the Group 1 Mortgage Loans to
      date
      are greater than the then applicable Trigger Amount, the Group 1 Senior
      Prepayment Percentage for Collateral Pool 1 will be the greater of (x) the
      Group
      1 Senior Prepayment Percentage for such Distribution Date or (y) the Group
      1
      Senior Prepayment Percentage for the immediately preceding Distribution
      Date.

     

    Notwithstanding
      the above, if on any Distribution Date (a) the Subordinate Percentage for
      Collateral Pool 1, prior to giving effect to any distributions on such
      Distribution Date, equals or exceeds two times the initial Subordinate
      Percentage for Collateral Pool 1 as of the Cut-Off Date, (b) the provisions
      of
      clause (i) of the second preceding paragraph are met and (c) (i) on or prior
      to
      the Distribution Date occurring in February 2010, cumulative Realized Losses
      on
      the Group 1 Mortgage Loans as of the end of the related Prepayment Period do
      not
      exceed 20% of the initial aggregate Certificate Principal Balance of the Group
      1
      Subordinate Certificates and (ii) after the Distribution Date occurring in
      February 2010, cumulative Realized Losses on the Group 1 Mortgage Loans as
      of
      the end of the Prepayment Period do not exceed 30% of the initial aggregate
      Certificate Principal Balance of the Group 1 Subordinate Certificates, then
      the
      Group 1 Senior Prepayment Percentage for such Distribution Date will equal
      the
      related Group 1 Senior Percentage plus 50% of the Group 1 Subordinate Percentage
      for such Distribution Date, if such Distribution Date is prior to March 2010,
      and will equal the Group 1 Senior Percentage for such Distribution Date, if
      such
      Distribution Date occurs on or after March 2010.

     

    Upon
      reduction of the Certificate Principal Balance of the Group 1 Class A
      Certificates to zero, the Group 1 Senior Prepayment Percentage will equal
      0%.

      aggregate of the Monthly Payments due on or before the Due Date relating to
      such
      Distribution Date and received by the Master Servicer (or a Sub-Servicer on
      its
      behalf) on or prior to the related Determination Date, after deduction of the
      applicable Servicing Fee and any applicable lender-paid primary mortgage
      insurance premium (b) Liquidation Proceeds, Insurance Proceeds, Principal
      Prepayments, proceeds from repurchases of and substitutions for the related

      Group 2 Mortgage Loans of (a) amounts reimbursable to the Depositor, the Master
      Servicer, the Trustee, the Trust Administrator, Citibank or a Custodian pursuant
      to Section 6.03 or Section 8.05 or otherwise payable in respect of Extraordinary

      by the Master Servicer or to be withdrawn by the Master Servicer from the
      Collection Account pursuant to Section 3.18.

     

    Notwithstanding
      the foregoing, the Group 2 Available Distribution Amount for a Loan Group and

      Overcollateralized Loan Group) by any applicable Diverted Interest Amount or
      Class A Principal Adjustment Amount, in each case for such Distribution
      Date.

     

    Provided,
      that, on any Distribution Date on which there are Group 2 Class A Certificates
      relating to only one Loan Group remaining outstanding, the Group 2 Available
      Distribution Amount for that Distribution Date will be calculated on an
      aggregate Collateral Pool 2 basis, without regard to the related Loan
      Group.

     

    Notwithstanding
      the foregoing, in the event that the amount received during a Due Period in
      connection with the foreclosure of a Mortgage Loan in Collateral Pool 2 exceeds
      the outstanding principal balance of such Mortgage Loan, such amounts shall
      be
      included in the Group 2 Available Distribution Amount only to the extent of
      Realized Losses incurred during the related Due Period with respect to Mortgage
      Loans in Collateral Pool 2 and the remainder will be held in a reserve fund
      established by or on behalf of the Trust Administrator in order to offset any
      future Realized Losses incurred. Prepayment premiums or charges collected in
      respect of the Mortgage Loans included in Collateral Pool 2 will be retained
      by
      the Master Servicer or the related Sub-Servicer and will not be included in
      the

    provided,
      however, no reduction to a Group 2 Senior Prepayment Percentage
      described above shall be made as of any Distribution Date unless (i) the

      of
      the end of the Prepayment Period do not exceed 30% of the initial aggregate
      Certificate Principal Balance of the Group 2 Subordinate Certificates, then
      the
      Group 2 Senior Prepayment Percentage for such Distribution Date and each Loan
      Group within Collateral Pool 2 will equal the related Group 2 Senior Percentage
      plus 50% of the related Group 2 Subordinate Percentage for such Distribution
      Date, if such Distribution Date is prior to March 2010, and will equal the

      shall be 100%.

     

    Upon
      reduction of the Certificate Principal Balances of the related Group 2 Class
      A
      Certificates to zero, the Group 2 Senior Prepayment Percentage for the related
      Loan Group shall be 0%.

                2.01  

            	
              Conveyance
                of Mortgage Loans.

            


    

     

    The
      Depositor, concurrently with the execution and delivery hereof, does hereby
      transfer, assign, set over and otherwise convey to the Trustee without recourse
      for the benefit of the Certificateholders all the right, title and interest
      of

      Schedule, the rights of the Depositor under the Mortgage Loan Purchase Agreement
      (except Section 18 thereof), and all other assets included or to be included

      receipt of the same.

     

    In
      connection with such transfer and assignment, the Depositor does hereby deliver
      to, and deposit with, the Trustee or a Custodian on its behalf, the following
      documents or instruments (a “Mortgage File”) with respect to each Mortgage Loan
      so transferred and assigned:

     

    (i)  The
      Mortgage Note, endorsed by manual or facsimile signature without recourse by

      Trustee;

     

    (ii)  The
      original recorded Mortgage, noting the presence of the MIN of the Mortgage
      Loan
      and language indicating that the Mortgage Loan is a MOM Loan if the Mortgage
      Loan is a MOM Loan, with evidence of recording thereon or a copy of the Mortgage
      certified by the public recording office in those jurisdictions where the public
      recording office retains the original;

     

    (iii)  Unless
      the Mortgage Loan is registered on the MERS® System, an assignment to the
      Trustee in recordable form of the Mortgage which may be included, where
      permitted by local law, in a blanket assignment or assignments of the Mortgage
      to the Trustee, including any intervening assignments and showing a complete
      chain of title from the original mortgagee named under the Mortgage to the
      Person assigning the Mortgage Loan to the Trustee (or to MERS, noting the
      presence of the MIN, if the Mortgage Loan is registered on the MERS®
System);

     

    (iv)  Any
      original assumption, modification, buydown or conversion-to- fixed-interest-rate
      agreement applicable to the Mortgage Loan;

     

    (v)  With
      respect to any Mortgage Loan listed on the Mortgage Loan Schedule as subject
      to
      a Primary Mortgage Insurance Policy, the original Primary Mortgage Insurance
      Policy or certificate or a copy thereof;

     

    (vi)  The
      original or a copy of the title insurance policy (which may be a certificate
      or
      a short form policy relating to a master policy of title insurance) pertaining
      to the Mortgaged Property, or in the event such original title policy is
      unavailable, a copy of the preliminary title report and the lender’s recording
      instructions, with the original to be delivered within 180 days of the Closing
      Date or an attorney’s opinion of title in jurisdictions where such is the
      customary evidence of title; and

     

    (vii)  [reserved].

     

    In
      instances where an original recorded Mortgage cannot be delivered by the
      Depositor to the Trustee (or a Custodian on behalf of the Trustee) prior to
      or
      concurrently with the execution and delivery of this Agreement, due to a delay
      in connection with the recording of such Mortgage, the Depositor may, (a) in
      lieu of delivering such original recorded Mortgage referred to in clause (ii)
      above, deliver to the Trustee (or a Custodian on behalf of the Trustee) a copy
      thereof, provided that the Depositor certifies that the original Mortgage has
      been delivered to a title insurance company for recordation after receipt of
      its
      policy of title insurance or binder therefor (which may be a certificate
      relating to a master policy of title insurance), and (b) in lieu of delivering
      the completed assignment in recordable form referred to in clause (iii) above
      to
      the Trustee (or a Custodian on behalf of the Trustee), deliver such assignment
      to the Trustee (or a Custodian on behalf of the Trustee) completed except for
      recording information. In all such instances, the Depositor will deliver the
      original recorded Mortgage and completed assignment (if applicable) to the
      Trustee (or a Custodian on behalf of the Trustee) promptly upon receipt of
      such
      Mortgage. In instances where an original recorded Mortgage has been lost or
      misplaced, the Depositor or the related title insurance company may deliver,
      in
      lieu of such Mortgage, a copy of such Mortgage bearing recordation information
      and certified as true and correct by the office in which recordation thereof
      was
      made. In instances where the original or a copy of the title insurance policy
      referred to in clause (vi) above (which may be a certificate relating to a
      master policy of title insurance) pertaining to the Mortgaged Property relating
      to a Mortgage Loan cannot be delivered by the Depositor to the Trustee (or
      a
      Custodian on behalf of the Trustee) prior to or concurrently with the execution
      and delivery of this Agreement because such policy is not yet available, the
      Depositor may, in lieu of delivering the original or a copy of such title
      insurance referred to in clause (vi) above, deliver to the Trustee (or a
      Custodian on behalf of the Trustee) a binder with respect to such policy (which
      may be a certificate relating to a master policy of title insurance) and deliver
      the original or a copy of such policy (which may be a certificate relating
      to a
      master policy of title insurance) to the Trustee (or a Custodian on behalf
      of
      the Trustee) within 180 days of the Closing Date, in instances where an original
      assumption, modification, buydown or conversion-to-fixed-interest-rate agreement
      cannot be delivered by the Depositor to the Trustee (or a Custodian on behalf
      of
      the Trustee) prior to or concurrently with the execution and delivery of this
      Agreement, the Depositor may, in lieu of delivering the original of such
      agreement referred to in clause (iv) above, deliver a certified copy
      thereof.

     

    To
      the
      extent not already recorded, except with respect to any Mortgage Loan for which
      MERS is identified on the Mortgage or on a properly recorded assignment of
      the
      Mortgage as the mortgagee of record, the Master Servicer, at the expense of
      the
      Seller shall promptly (and in no event later than five Business Days following
      the later of the Closing Date and the date of receipt by the Master Servicer
      of
      the recording information for a Mortgage) submit or cause to be submitted for
      recording, at no expense to any Trust REMIC, in the appropriate public office
      for real property records, each Assignment delivered to it pursuant to (iii)
      above. In the event that any such Assignment is lost or returned unrecorded
      because of a defect therein, the Master Servicer, at the expense of the Seller,
      shall promptly prepare or cause to be prepared a substitute Assignment or cure
      or cause to be cured such defect, as the case may be, and thereafter cause
      each
      such Assignment to be duly recorded. Notwithstanding the foregoing, but without
      limiting the requirement that such Assignments be in recordable form, neither
      the Master Servicer nor the Trustee shall be required to submit or cause to
      be
      submitted for recording any Assignment delivered to it or a Custodian pursuant
      to (iii) above if such recordation shall not, as of the Closing Date, be
      required by the Rating Agencies, as a condition to their assignment on the
      Closing Date of their initial ratings to the Certificates, as evidenced by
      the
      delivery by the Rating Agencies of their ratings letters on the Closing Date;
      provided, however, notwithstanding the foregoing, the Master Servicer shall
      submit each Assignment for recording, at no expense to the Trust Fund or the
      Master Servicer, upon the earliest to occur of: (A) reasonable direction by
      Holders of Certificates entitled to at least 25% of the Voting Rights, (B)
      the
      occurrence of a Master Servicer Event of Termination, (C) the occurrence of
      a
      bankruptcy, insolvency or foreclosure relating to the Seller, (D) the occurrence
      of a servicing transfer as described in Section 7.02 of this Agreement and
      (E)
      with respect to any one Assignment the occurrence of a foreclosure relating
      to
      the Mortgagor under the related Mortgage. Notwithstanding the foregoing, if
      the
      Seller fails to pay the cost of recording the Assignments, such expense will
      be
      paid by the Master Servicer and the Master Servicer shall be reimbursed for
      such
      expenses by the Trust as set forth herein.

     

    In
      connection with the assignment of any Mortgage Loan registered on the MERS
      System, the Depositor further agrees that it will cause, within 30 Business
      Days
      after the Closing Date, the MERS System to indicate that such Mortgage Loans
      have been assigned by the Depositor to the Trustee in accordance with this
      Agreement for the benefit of the Certificateholders by including in such
      computer files (a) the code in the field which identifies the specific Trustee
      and (b) the code in the field “Pool Field” which  identifies the
      series of the Certificates issued in connection with such Mortgage Loans. The
      Depositor  further agrees that it will not, and will not permit the
      Master Servicer to, and the Master Servicer agrees that it will not and will
      not
      permit a Sub-Servicer to, alter the codes referenced in this paragraph with
      respect to any Mortgage Loan during the term of this Agreement unless and until
      such Mortgage Loan is repurchased in accordance with the terms of this
      Agreement.

     

    With
      respect to a maximum of approximately 5.00% of the Original Mortgage Loans,
      by
      outstanding principal balance of the Original Mortgage Loans as of the Cut-off
      Date, if any original Mortgage Note referred to in (i) above cannot be located,
      the obligations of the Depositor to deliver such documents shall be deemed
      to be
      satisfied upon delivery to the Trustee (or a Custodian on behalf of the Trustee)
      of a photocopy of such Mortgage Note, if available, with a lost note affidavit.
      If any of the original Mortgage Notes for which a lost note affidavit was
      delivered to the Trustee (or a Custodian on behalf of the Trustee) is
      subsequently located, such original Mortgage Note shall be delivered to the
      Trustee (or a Custodian on behalf of the Trustee) within three Business
      Days.

     

    The
      Depositor shall deliver or cause to be delivered to the Trustee (or a Custodian
      on behalf of the Trustee) promptly upon receipt thereof any other original
      documents constituting a part of a Mortgage File received with respect to any
      Mortgage Loan, including, but not limited to, any original documents evidencing
      an assumption, modification, consolidation or extension of any Mortgage
      Loan.

     

    All
      original documents relating to the Mortgage Loans that are not delivered to
      the
      Trustee (or a Custodian on behalf of the Trustee) are and shall be held by
      or on
      behalf of the Seller, the Depositor or the Master Servicer, as the case may
      be,
      in trust for the benefit of the Trustee on behalf of the Certificateholders.
      In
      the event that any such original document is required pursuant to the terms
      of
      this Section to be a part of a Mortgage File, such document shall be delivered
      promptly to the Trustee (or a Custodian on behalf of the Trustee). Any such
      original document delivered to or held by the Depositor that is not required
      pursuant to the terms of this Section to be a part of a Mortgage File, shall
      be
      delivered promptly to the Master Servicer.

     

    Wherever
      it is provided in this Section 2.01 that any document, evidence or information
      relating to a Mortgage Loan be delivered or supplied to the Trustee, the
      Depositor shall do so by delivery thereof to the Trustee or Custodian on behalf
      of the Trustee.

     

    It
      is
      agreed and understood by the parties hereto that it is not intended that any
      Mortgage Loan to be included in the Trust Fund be (i) a “High-Cost Home Loan” as
      defined in the New Jersey Home Ownership Act effective November 27, 2003, (ii)
      a
“High-Cost Home Loan” as defined in the New Mexico Home Loan Protection Act
      effective January 1, 2004, (iii) a “High-Cost Home Mortgage Loan” as defined in
      the Massachusetts Predatory Home Loan Practices Act effective November 7, 2004
      or (iv) a “High Cost Home Loan” as defined in the Indiana Home Loan Practices
      Act effective January 1, 2005.  It is agreed and understood by the
      parties hereto that it is not intended that any Mortgage Loan to be included
      in
      the Trust Fund not comply in all material respects with applicable local, state
      and federal laws, including, but not limited to, all applicable predatory and
      abusive lending laws.

              Acceptance
                of the Trust Fund by the Trustee.

            


    

     

    Subject
      to the provisions of Section 2.01 and subject to any exceptions noted on an
      exception report delivered by or on behalf of the Trustee, the Trustee
      acknowledges receipt of the documents referred to in Section 2.01 (other than
      such documents described in Section 2.01(iv)) and all other assets included
      in
      the definition of “Trust Fund” and declares that it holds and will hold such
      documents and the other documents delivered to it constituting the Mortgage
      File, and that it holds or will hold all such assets and such other assets
      included in the definition of “Trust Fund” in trust for the exclusive use and
      benefit of all present and future Certificateholders.

     

    The
      Trustee, by execution and delivery hereof, acknowledges receipt, subject to
      the
      review described in the succeeding sentence, of the documents and other property
      referred to in Section 2.01 and declares that the Trustee (or a Custodian on
      behalf of the Trustee) holds and will hold such documents and other property,
      including property yet to be received in the Trust Fund, in trust, upon the
      trusts herein set forth, for the benefit of all present and future
      Certificateholders. The Trustee or a Custodian on its behalf shall, for the
      benefit of the Trustee and the Certificateholders, review each Mortgage File
      within 90 days after execution and delivery of this Agreement, to ascertain
      that
      all required documents have been executed, received and recorded, if applicable,
      and that such documents relate to the Mortgage Loans. If in the course of such
      review the Trustee or a Custodian on its behalf finds a document or documents
      constituting a part of a Mortgage File to be defective in any material respect,
      the Trustee or a Custodian on its behalf shall promptly so notify the Depositor,
      the Trust Administrator, the Paying Agent, the Seller, the Master Servicer
      and,
      if such notice is from a Custodian on the Trustee’s behalf, the Trustee. In
      addition, upon the discovery by the Depositor, the Master Servicer, the Trust
      Administrator, the Paying Agent or the Trustee of a breach of any of the
      representations and warranties made by the Seller in the Mortgage Loan Purchase
      Agreement in respect of any Mortgage Loan which materially adversely affects
      such Mortgage Loan or the interests of the related Certificateholders in such
      Mortgage Loan, the party discovering such breach shall give prompt written
      notice to the other parties.

     

    The
      Depositor and the Trustee intend that the assignment and transfer herein
      contemplated constitute a sale of the Mortgage Loans, the related Mortgage
      Notes
      and the related documents, conveying good title thereto free and clear of any
      liens and encumbrances, from the Depositor to the Trustee in trust for the
      benefit of the Certificateholders and that such property not be part of the
      Depositor’s estate or property of the Depositor in the event of any insolvency
      by the Depositor. In the event that such conveyance is deemed to be, or to
      be
      made as security for, a loan, the parties intend that the Depositor shall be
      deemed to have granted and does hereby grant to the Trustee a first priority
      perfected security interest in all of the Depositor’s right, title and interest
      in and to the Mortgage Loans, the related Mortgage Notes and the related
      documents, and that this Agreement shall constitute a security agreement under
      applicable law.

     

    The
      Trustee may, concurrently with the execution and delivery hereof or at any
      time
      thereafter, enter into a custodial agreement with a Custodian pursuant to which
      the Trustee appoints a Custodian to hold the Mortgage Files on behalf of the
      Trustee for the benefit of the Trustee and all present and future
      Certificateholders, which may provide that the Custodian shall, on behalf of
      the
      Trustee, conduct the review of each Mortgage File required under the first
      paragraph of this Section 2.02. Initially, Citibank, N.A., is appointed as
      Custodian with respect to the Mortgage Files of all the Countrywide Mortgage
      Loans, Fifth Third Mortgage Loans and  the National City Mortgage
      Loans and Wells Fargo Bank, N.A. is appointed Custodian with respect to the
      Mortgage Files of all the Wells Fargo Mortgage Loans and, notwithstanding
      anything to the contrary herein, it is understood that such initial Custodians
      shall be responsible for the review contemplated in the second paragraph of
      this
      Section 2.02 and for all other functions relating to the receipt, review,
      reporting and certification provided for herein with respect to their respective
      Mortgage Files (other than ownership thereof for the benefit of the
      Certificateholders and related duties and obligations set forth
      herein).

              Repurchase
                or Substitution of Mortgage Loans by the Seller or the
                Depositor.

            


    

     

    (a)  Upon
      discovery or receipt of notice by the Depositor, the Master Servicer, the Trust
      Administrator or the Trustee of any materially defective document in, or that
      a
      document is missing from, a Mortgage File or of the breach by the Seller of
      any
      representation, warranty or covenant under the Mortgage Loan Purchase Agreement
      in respect of any Mortgage Loan which materially adversely affects the value
      of
      such Mortgage Loan or the interest therein of the Certificateholders, the party
      so discovering or receiving notice shall promptly notify the other parties
      to
      this Agreement, and the Trustee thereupon shall promptly notify the Seller
      of
      such defect, missing document or breach and request that the Seller deliver
      such
      missing document or cure such defect or breach within 90 days from the date
      the
      Seller was notified of such missing document, defect or breach, and if the
      Seller does not deliver such missing document or cure such defect or breach
      in
      all material respects during such period, the Trustee shall enforce the
      obligations of the Seller under the Mortgage Loan Purchase Agreement (i) to
      repurchase such Mortgage Loan from REMIC I-A or REMIC II-A at the Purchase
      Price
      within 90 days after the date on which the Seller was notified (subject to
      Section 2.03(e)) of such missing document, defect or breach, and (ii) to
      indemnify the Trust Fund in respect of such missing document, defect or breach,
      in the case of each of (i) and (ii),  if and to the extent that the
      Seller is obligated to do so under the Mortgage Loan Purchase Agreement. The
      Purchase Price for the repurchased Mortgage Loan and any indemnification shall
      be remitted by the Seller to the Master Servicer for deposit into the Collection
      Account, and the Trust Administrator, upon receipt of written notice from the
      Master Servicer of such deposit, shall give written notice to the Trustee that
      such deposit has taken place and the Trustee shall release (or cause a Custodian
      to release on its behalf) to the Seller the related Mortgage File, and the
      Trustee and the Trust Administrator shall execute and deliver such instruments
      of transfer or assignment, in each case without recourse, as the Seller shall
      furnish to it and as shall be necessary to vest in the Seller any Mortgage
      Loan
      released pursuant hereto, and the Trustee and the Trust Administrator shall
      have
      no further responsibility with regard to such Mortgage File. In furtherance
      of
      the foregoing, if the Seller is not a member of MERS and repurchases a Mortgage
      Loan which is registered on the MERS System, the Seller pursuant to the Mortgage
      Loan Purchase Agreement at its own expense and without any right of
      reimbursement, shall cause MERS to execute and deliver an assignment of the
      Mortgage in recordable form to transfer the Mortgage from MERS to the Seller
      and
      shall cause such Mortgage to be removed from registration on the MERS System
      in
      accordance with MERS rules and regulations. In lieu of repurchasing any such
      Mortgage Loan as provided above, if so provided in the Mortgage Loan Purchase
      Agreement the Seller may cause such Mortgage Loan to be removed from REMIC
      I-A
      or REMIC II-A (in which case it shall become a Deleted Mortgage Loan) and
      substitute one or more Qualified Substitute Mortgage Loans in the manner and
      subject to the limitations set forth in Section 2.03(d). It is understood and
      agreed that the obligation of the Seller to cure or to repurchase (or to
      substitute for) any Mortgage Loan as to which a document is missing, a material
      defect in a constituent document exists or as to which such a breach has
      occurred and is continuing, and if and to the extent provided in the Mortgage
      Loan Purchase Agreement to perform any applicable indemnification obligations
      with respect to any such omission, defect or breach, as provided in the Mortgage
      Loan Purchase Agreement, shall constitute the only remedies respecting such
      omission, defect or breach available to the Trustee or the Trust Administrator
      on behalf of the Certificateholders.

     

    (b)  Reserved.

     

    (c)  Within
      90
      days of the earlier of discovery by the Master Servicer or receipt of notice
      by
      the Master Servicer of the breach of any representation, warranty or covenant
      of
      the Master Servicer set forth in Section 2.05 which materially and adversely
      affects the interests of the Certificateholders in any Mortgage Loan, the Master
      Servicer shall cure such breach in all material respects.

     

    (d)  Any
      substitution of Qualified Substitute Mortgage Loans for Deleted Mortgage Loans
      made pursuant to Section 2.03(a) must be effected prior to the date which is
      two
      years after the Startup Day for REMIC I-A or REMIC II-A.

     

    As
      to any
      Deleted Mortgage Loan for which the Seller substitutes a Qualified Substitute
      Mortgage Loan or Loans, such substitution shall be effected by the Seller
      delivering to the Trustee (or to a Custodian on behalf of the Trustee, as
      applicable), for such Qualified Substitute Mortgage Loan or Loans, the Mortgage
      Note, the Mortgage, the Assignment in blank or to the Trustee, and such other
      documents and agreements, with all necessary endorsements thereon, as are
      required by Section 2.01, together with an Officers’ Certificate providing that
      each such Qualified Substitute Mortgage Loan satisfies the definition thereof
      and specifying the Substitution Shortfall Amount (as described below), if any,
      in connection with such substitution. A Custodian on its behalf and on behalf
      of
      the Trustee shall, for the benefit of the Certificateholders, review each
      Mortgage File within 90 days after execution and delivery of this Agreement,
      to
      ascertain that all required documents have been executed, received and recorded,
      if applicable, and that such documents relate to the Mortgage Loans. If in
      the
      course of such review the Trustee or a Custodian on its behalf finds a document
      or documents constituting a part of a Mortgage File to be defective in any
      material respect, the Trustee or a Custodian on its behalf shall promptly so
      notify the Depositor, the Trust Administrator, the Seller and the Master
      Servicer. Monthly Payments due with respect to Qualified Substitute Mortgage
      Loans in the month of substitution are not part of the Trust Fund and will
      be
      retained by the Seller. For the month of substitution, distributions to
      Certificateholders will reflect the Monthly Payment due on such Deleted Mortgage
      Loan on or before the Due Date in the month of substitution, and the Seller
      shall thereafter be entitled to retain all amounts subsequently received in
      respect of such Deleted Mortgage Loan. The Trust Administrator shall give or
      cause to be given written notice to the Trustee and the Certificateholders
      that
      such substitution has taken place, and the Trust Administrator shall amend
      or
      cause a Custodian to amend the Mortgage Loan Schedule to reflect the removal
      of
      such Deleted Mortgage Loan from the terms of this Agreement and the substitution
      of the Qualified Substitute Mortgage Loan or Loans and, upon receipt thereof,
      shall deliver a copy of such amended Mortgage Loan Schedule to the Master
      Servicer. Upon such substitution, such Qualified Substitute Mortgage Loan or
      Loans shall constitute part of the Mortgage Pool and shall be subject in all
      respects to the terms of this Agreement and the Mortgage Loan Purchase Agreement
      (including all applicable representations and warranties thereof included in
      the
      Mortgage Loan Purchase Agreement), in each case as of the date of
      substitution.

     

    For
      any
      month in which the Seller substitutes one or more Qualified Substitute Mortgage
      Loans for one or more Deleted Mortgage Loans, the Master Servicer will determine
      the amount (the “Substitution Shortfall Amount”), if any, by which the aggregate
      Purchase Price of all such Deleted Mortgage Loans exceeds the aggregate of,
      as
      to each such Qualified Substitute Mortgage Loan, the Scheduled Principal Balance
      thereof as of the date of substitution, together with one month’s interest on
      such Scheduled Principal Balance at the applicable Mortgage Loan Remittance
      Rate. On the date of such substitution, the Trustee will monitor the obligation
      of the Seller to deliver or cause to be delivered, and shall request that such
      delivery be to the Master Servicer for deposit in the Collection Account, an
      amount equal to the Substitution Shortfall Amount, if any, and the Trustee
      (or a
      Custodian on behalf of the Trustee, as applicable), upon receipt of the related
      Qualified Substitute Mortgage Loan or Loans and written notice given by the
      Master Servicer of such deposit, shall release to the Seller the related
      Mortgage File or Files and the Trustee and the Trust Administrator shall execute
      and deliver such instruments of transfer or assignment, in each case without
      recourse, as the Seller shall deliver to it and as shall be necessary to vest
      therein any Deleted Mortgage Loan released pursuant hereto.

     

    In
      addition, the Seller shall obtain at its own expense and deliver to the Trustee
      and the Trust Administrator an Opinion of Counsel to the effect that such
      substitution will not cause (a) any federal tax to be imposed on any Trust
      REMIC, including without limitation, any federal tax imposed on “prohibited
      transactions” under Section 860F(a)(1) of the Code or on “contributions after
      the startup date” under Section 860G(d)(1) of the Code, or (b) any Trust REMIC
      to fail to qualify as a REMIC at any time that any Certificate is
      outstanding.

     

    (e)  Upon
      discovery by the Depositor, the Master Servicer, the Trust Administrator or
      the
      Trustee that any Mortgage Loan does not constitute a “qualified mortgage” within
      the meaning of Section 860G(a)(3) of the Code, the party discovering such fact
      shall within two Business Days give written notice thereof to the other parties
      to this Agreement, and the Trustee shall give written notice thereof to the
      Seller. In connection therewith, the Seller pursuant to the Mortgage Loan
      Purchase Agreement or the Depositor pursuant to this Agreement shall repurchase
      or, subject to the limitations set forth in Section 2.03(d), substitute one
      or
      more Qualified Substitute Mortgage Loans for the affected Mortgage Loan within
      90 days of the earlier of discovery or receipt of such notice with respect
      to
      such affected Mortgage Loan. Such repurchase or substitution shall be made
      by
      (i) the Seller if the affected Mortgage Loan’s status as a non-qualified
      mortgage is or results from a breach of any representation, warranty or covenant
      made by the Seller under the Mortgage Loan Purchase Agreement or (ii) the
      Depositor, if the affected Mortgage Loan’s status as a non-qualified mortgage is
      a breach of no representation or warranty. Any such repurchase or substitution
      shall be made in the same manner as set forth in Sections 2.03(a) and 2.03(d).
      The Trustee shall reconvey to the Depositor or the Seller, as the case may
      be,
      the Mortgage Loan to be released pursuant hereto in the same manner, and on
      the
      same terms and conditions, as it would a Mortgage Loan repurchased by the Seller
      for breach of a representation or warranty.

    OF
      THE
      MORTGAGE LOANS

     

    
      	
              SECTION
                3.01  

            	
              Master
                Servicer to Act as Master Servicer.

            


    

     

    The
      Master Servicer shall service and administer the Mortgage Loans on behalf of
      the
      Trustee and in the best interests of and for the benefit of the
      Certificateholders (as determined by the Master Servicer in its reasonable
      judgment) in accordance with the terms of this Agreement and the respective
      Mortgage Loans and, to the extent consistent with such terms, in the same manner
      in which it services and administers similar mortgage loans for its own
      portfolio, giving due consideration to customary and usual standards of practice
      of prudent mortgage lenders and loan servicers administering similar mortgage
      loans but without regard to:

     

    (i)  any
      relationship that the Master Servicer, any Sub-Servicer or any Affiliate of
      the
      Master Servicer or any Sub-Servicer may have with the related
      Mortgagor;

     

    (ii)  the
      ownership of any Certificate by the Master Servicer or any Affiliate of the
      Master Servicer;

     

    (iii)  the
      Master Servicer’s obligation to make P&I Advances or Servicing Advances;
      or

     

    (iv)  the
      Master Servicer’s or any Sub-Servicer’s right to receive compensation for its
      services hereunder or with respect to any particular transaction.

     

    To
      the
      extent consistent with the foregoing, the Master Servicer shall also seek to
      maximize the timely and complete recovery of principal and interest on the
      Mortgage Notes. Subject only to the above-described servicing standards and
      the
      terms of this Agreement and of the respective Mortgage Loans, the Master
      Servicer shall have full power and authority, acting alone or through
      Sub-Servicers as provided in Section 3.02, to do or cause to be done any and
      all
      things in connection with such servicing and administration which it may deem
      necessary or desirable. Without limiting the generality of the foregoing, the
      Master Servicer in its own name or in the name of a Sub-Servicer is hereby
      authorized and empowered by the Trustee when the Master Servicer believes it
      appropriate in its best judgment in accordance with the servicing standards
      set
      forth above, to execute and deliver, on behalf of the Certificateholders and
      the
      Trustee, and upon notice to the Trustee, any and all instruments of satisfaction
      or cancellation, or of partial or full release or discharge, and all other
      comparable instruments, with respect to the Mortgage Loans and the Mortgaged
      Properties and to institute foreclosure proceedings or obtain a deed-in-lieu
      of
      foreclosure so as to convert the ownership of such properties, and to hold
      or
      cause to be held title to such properties, on behalf of the Trustee and
      Certificateholders. The Master Servicer shall service and administer the
      Mortgage Loans in accordance with applicable state and federal law and shall
      provide to the Mortgagors any reports required to be provided to them thereby.
      The Master Servicer shall also comply in the performance of this Agreement
      with
      all reasonable rules and requirements of each insurer under each Primary
      Mortgage Insurance Policy and any standard hazard insurance policy. Subject
      to
      Section 3.17, the Trustee shall execute, at the written request of the Master
      Servicer, and furnish to the Master Servicer and any Sub-Servicer such documents
      as are necessary or appropriate to enable the Master Servicer or any
      Sub-Servicer to carry out their servicing and administrative duties hereunder,
      and the Trustee hereby grants to the Master Servicer a power of attorney to
      carry out such duties. The Trustee shall not be liable for the actions of the
      Master Servicer or any Sub-Servicers under such powers of attorney.

     

    In
      accordance with the standards of the preceding paragraph, the Master Servicer
      shall advance or cause to be advanced funds as necessary for the purpose of
      effecting the timely payment of taxes and assessments on the Mortgaged
      Properties, which advances shall be Servicing Advances reimbursable in the
      first
      instance from related collections from the Mortgagors pursuant to Section 3.09,
      and further as provided in Section 3.11. Any cost incurred by the Master
      Servicer or by Sub- Servicers in effecting the timely payment of taxes and
      assessments on a Mortgaged Property shall not, for the purpose of calculating
      distributions to Certificateholders, be added to the unpaid principal balance
      of
      the related Mortgage Loan, notwithstanding that the terms of such Mortgage
      Loan
      so permit.

     

    The
      Master Servicer further is authorized and empowered by the Trustee, on behalf
      of
      the Certificateholders and the Trustee, in its own name or in the name of the
      Sub-Servicer, when the Master Servicer or the Sub-Servicer, as the case may
      be,
      believes it is appropriate in its best judgment to register any Mortgage Loan
      on
      the MERS System, or cause the removal from the registration of any Mortgage
      Loan
      on the MERS System, to execute and deliver, on behalf of the Trustee and the
      Certificateholders or any of them, any and all instruments of assignment and
      other comparable instruments with respect to such assignment or re-recording
      of
      a Mortgage in the name of MERS, solely as nominee for the Trustee and its
      successors and assigns. Any reasonable expenses (i) incurred as a result of
      MERS
      discontinuing or becoming unable to continue operations in connection with
      the
      MERS System or (ii) if the affected Mortgage Loan is in default or, in the
      judgment of the Master Servicer, such default is reasonably foreseeable,
      incurred in connection with the actions described in the preceding sentence,
      shall be subject to withdrawal by the Master Servicer from the Collection
      Account.

     

    Notwithstanding
      anything in this Agreement to the contrary, the Master Servicer may not make
      any
      future advances with respect to a Mortgage Loan (except as provided in Section
      4.03) and the Master Servicer shall not (i) permit any modification with respect
      to any Mortgage Loan (except with respect to a Mortgage Loan that is in default
      or, in the judgment of the Master Servicer, such default is reasonably
      foreseeable) that would change the Mortgage Rate, reduce or increase the
      principal balance (except for reductions resulting from actual payments of
      principal) or change the final maturity date on such Mortgage Loan or (ii)
      permit any modification, waiver or amendment of any term of any Mortgage Loan
      that would both (A) effect an exchange or reissuance of such Mortgage Loan
      under
      Section 1001 of the Code (or final, temporary or proposed Treasury regulations
      promulgated thereunder) and (B) cause any Trust REMIC to fail to qualify as
      a
      REMIC under the Code or the imposition of any tax on “prohibited transactions”
or “contributions after the startup date” under the REMIC
      Provisions.  Consistent with the foregoing, in connection with a
      partial Principal Prepayment, the Master Servicer may at its option reduce
      or
      permit a Sub-Servicer to reduce the scheduled Monthly Payments on the related
      Mortgage Loan so that the remaining outstanding principal amount owed under
      such
      Mortgage Loan will be paid in equal monthly installments of principal and
      interest by the originally scheduled maturity date.  In addition, in
      connection with any modification of a Mortgage Loan that is entered into by
      a
      Mortgagor in lieu of refinancing and that is not permitted by this paragraph
      or
      by Section 3.07, the Master Servicer shall treat such modification for remitting
      and reporting purposes as a Principal Prepayment in full to the Trust occurring
      concurrently with the origination of a new mortgage loan, which is not in the
      Trust, to the Mortgagor.  For any such Mortgage Loan that has been so
      deemed the subject of a Principal Prepayment in full, upon written notice from
      the Master Servicer of the deposit into the Collection Account of funds in
      an
      amount equal to all amounts that would be owed to the Trust by the related
      Mortgagor if such deemed Principal Prepayment were an actual Principal
      Prepayment in full, the Trustee and the Trust Administrator shall execute and
      deliver such instruments of transfer or assignment, in each case without
      recourse, as the Master Servicer or the applicable Sub-Servicer shall furnish
      to
      it and as shall be necessary to vest in the designated successor owner of such
      Mortgage Loan specified in such instruments such Mortgage Loan released pursuant
      hereto, and the Trustee and the Trust Administrator shall have no further
      responsibility with regard to such Mortgage Loan or the related Mortgage
      File.

     

    The
      Master Servicer may delegate its responsibilities under this Agreement;
      provided, however, that no such delegation shall release the Master Servicer
      from the responsibilities or liabilities arising under this
      Agreement.

     

    The
      Master Servicer shall accurately and fully report (or cause each Sub-Servicer
      to
      accurately and fully report), its borrower credit files to each of the credit
      repositories in a timely manner.

              Sub-Servicing
                Agreements Between the Master Servicer and
                Sub-Servicers.

            


    

     

    (a)  The
      Master Servicer may enter into Sub-Servicing Agreements (provided that such
      agreements would not result in a withdrawal or a downgrading by the Rating
      Agencies of the rating on any Class of Certificates) with Sub-Servicers, for
      the
      servicing and administration of the Mortgage Loans.  As of the Cut-Off
      Date, Countrywide Home Loans Servicing LP is the Sub-Servicer with respect
      to
      the Countrywide Mortgage Loans and in such capacity Countrywide Home Loans
      Servicing LP will be primarily responsible for the servicing of such Mortgage
      Loans. As of the Cut-Off date, Fifth Third is the Sub-Servicer with respect
      to
      the Fifth Third Mortgage Loans and in such capacity Fifth Third will be
      primarily responsible for the servicing of such Mortgage Loans.  As of
      the Cut-Off Date, National City is the Sub-Servicer with respect to the National
      City Mortgage Loans and in such capacity National City Mortgage Co. will be
      primarily responsible for the servicing of such Mortgage Loans.  As of
      the Cut-Off Date, Wells Fargo is the Sub-Servicer with respect to the Wells
      Fargo Mortgage Loans and in such capacity Wells Fargo will be primarily
      responsible for the servicing of such Mortgage Loans.  As of the
      Cut-Off Date, CitiMortgage is the Sub-Servicer with respect to certain of the
      CitiMortgage Mortgage Loans and in such capacity CitiMortgage will be primarily
      responsible for the servicing of such Mortgage Loans.

     

    (b)  Each
      Sub-Servicer shall be (i) authorized to transact business in the state or states
      in which the related Mortgaged Properties it is to service are situated, if
      and
      to the extent required by applicable law to enable the Sub-Servicer to perform
      its obligations hereunder and under the Sub-Servicing Agreement, (ii) an
      institution approved as a mortgage loan originator by the Federal Housing
      Administration or an institution the deposit accounts of which are insured
      by
      the FDIC and (iii) a Freddie Mac or Fannie Mae approved mortgage servicer.
      Each
      Sub-Servicing Agreement must impose on the Sub-Servicer requirements conforming
      to the provisions set forth in Section 3.08 and provide for servicing of the
      Mortgage Loans consistent with the terms of this Agreement. The Master Servicer
      will examine each Sub-Servicing Agreement and will be familiar with the terms
      thereof. The terms of any Sub-Servicing Agreement will not be inconsistent
      with
      any of the provisions of this Agreement. The Master Servicer and the
      Sub-Servicers may enter into and make amendments to the Sub-Servicing Agreements
      or enter into different forms of Sub-Servicing Agreements; provided, however,
      that any such amendments or different forms shall be consistent with and not
      violate the provisions of this Agreement, and that no such amendment or
      different form shall be made or entered into which could be reasonably expected
      to be materially adverse to the interests of the Certificateholders, without
      the
      consent of the Holders of Certificates entitled to at least 66% of the Voting
      Rights. Any variation without the consent of the Holders of Certificates
      entitled to at least 66% of the Voting Rights from the provisions set forth
      in
      Section 3.08 relating to insurance or priority requirements of Sub-Servicing
      Accounts, or credits and charges to the Sub- Servicing Accounts or the timing
      and amount of remittances by the Sub-Servicers to the Master Servicer, are
      conclusively deemed to be inconsistent with this Agreement and therefore
      prohibited. The Master Servicer shall deliver to the Trustee and the Trust
      Administrator copies of all Sub-Servicing Agreements, and any amendments or
      modifications thereof, promptly upon the Master Servicer’s execution and
      delivery of such instruments.

     

    (c)  As
      part
      of its servicing activities hereunder, the Master Servicer (except as otherwise
      provided in the last sentence of this paragraph), for the benefit of the Trustee
      and the Certificateholders, shall enforce the obligations of each Sub-Servicer
      under the related Sub-Servicing Agreement and of the Seller under the Mortgage
      Loan Purchase Agreement, including, without limitation, any obligation to make
      advances in respect of delinquent payments as required by a Sub- Servicing
      Agreement, or to purchase a Mortgage Loan on account of missing or defective
      documentation or on account of a breach of a representation, warranty or
      covenant, as described in Section 2.03(a). Such enforcement, including, without
      limitation, the legal prosecution of claims, termination of Sub-Servicing
      Agreements, and the pursuit of other appropriate remedies, shall be in such
      form
      and carried out to such an extent and at such time as the Master Servicer,
      in
      its good faith business judgment, would require were it the owner of the related
      Mortgage Loans. The Master Servicer shall pay the costs of such enforcement
      at
      its own expense, and shall be reimbursed therefor only (i) from a general
      recovery resulting from such enforcement, to the extent, if any, that such
      recovery exceeds all amounts due in respect of the related Mortgage Loans,
      or
      (ii) from a specific recovery of costs, expenses or attorneys’ fees against the
      party against whom such enforcement is directed.

      Agreement in accordance with the terms and conditions of such Sub-Servicing
      Agreement. In the event of termination of any Sub-Servicer, all servicing
      obligations of such Sub-Servicer shall be assumed simultaneously by the Master
      Servicer without any act or deed on the part of such Sub-Servicer or the Master
      Servicer, and the Master Servicer either shall service directly the related
      Mortgage Loans or shall enter into a Sub-Servicing Agreement with a successor
      Sub-Servicer which qualifies under Section 3.02.

     

    Any
      Sub-Servicing Agreement (other than any Initial Sub-Servicing Agreement) shall
      include the provision that such agreement may be immediately terminated by
      the
      Trustee or the Trust Administrator without fee, in accordance with the terms
      of
      this Agreement, in the event that the Master Servicer shall, for any reason,
      no
      longer be the Master Servicer (including termination due to a Master Servicer
      Event of Default).

      to
      agreements or arrangements between the Master Servicer and a Sub-Servicer or
      reference to actions taken through a Sub-Servicer or otherwise, the Master
      Servicer shall remain obligated and primarily liable to the Trustee and the
      Certificateholders for the servicing and administering of the Mortgage Loans
      in
      accordance with the provisions of Section 3.01 without diminution of such
      obligation or liability by virtue of such Sub-Servicing Agreements or
      arrangements or by virtue of indemnification from the Sub-Servicer and to the
      same extent and under the same terms and conditions as if the Master Servicer
      alone were servicing and administering the Mortgage Loans. The Master Servicer
      shall be entitled to enter into any agreement with a Sub- Servicer for
      indemnification of the Master Servicer by such Sub-Servicer and nothing
      contained in this Agreement shall be deemed to limit or modify such
      indemnification.

    Any

      services relating to the Mortgage Loans involving a Sub-Servicer in its capacity
      as such shall be deemed to be between the Sub-Servicer and the Master Servicer
      alone, and the Trustee, the Trust Administrator and the Certificateholders
      shall
      not be deemed parties thereto and shall have no claims, rights, obligations,
      duties or liabilities with respect to the Sub-Servicer except as set forth
      in
      Section 3.06. The Master Servicer shall be solely liable for all fees owed
      by it
      to any Sub-Servicer, irrespective of whether the Master Servicer’s compensation
      pursuant to this Agreement is sufficient to pay such fees.

                or Termination of Sub-Servicing Agreements by

    In
      the
      event the Master Servicer shall for any reason no longer be the master servicer
      (including by reason of the occurrence of a Master Servicer Event of Default),
      the Trustee or its designee shall thereupon assume all of the rights and
      obligations of the Master Servicer under each Sub-Servicing Agreement that
      the
      Master Servicer may have entered into, unless the Trustee elects to terminate
      any Sub-Servicing Agreement in accordance with its terms as provided in Section
      3.03. Upon such assumption, the Trustee, its designee or the successor servicer
      for the Trustee appointed pursuant to Section 7.02 shall be deemed, subject
      to
      Section 3.03, to have assumed all of the Master Servicer’s interest therein and
      to have replaced the Master Servicer as a party to each Sub-Servicing Agreement
      to the same extent as if each Sub-Servicing Agreement had been assigned to
      the
      assuming party, except that (i) the Master Servicer shall not thereby be
      relieved of any liability or obligations under any Sub-Servicing Agreement
      and
      (ii) none of the Trustee, its designee or any successor Master Servicer shall
      be
      deemed to have assumed any liability or obligation of the Master Servicer that
      arose before it ceased to be the Master Servicer.

     

    The
      Master Servicer at its expense shall, upon request of the Trustee, deliver
      to
      the assuming party all documents and records relating to each Sub-Servicing
      Agreement and the Mortgage Loans then being serviced and an accounting of
      amounts collected and held by or on behalf of it, and otherwise use its best
      efforts to effect the orderly and efficient transfer of the Sub- Servicing
      Agreements to the assuming party.

              Collection
                of Certain Mortgage Loan Payments.

            


    

     

    The
      Master Servicer shall make reasonable efforts to collect all payments called
      for
      under the terms and provisions of the Mortgage Loans, and shall, to the extent
      such procedures shall be consistent with this Agreement and the terms and
      provisions of any related Primary Mortgage Insurance Policy and any other
      applicable insurance policies, follow such collection procedures as it would
      follow with respect to mortgage loans comparable to the Mortgage Loans and
      held
      for its own account. Consistent with the foregoing and the servicing standards
      set forth in Section 3.01, the Master Servicer may in its discretion (i) waive
      any late payment charge or, if applicable, penalty interest, only upon
      determining that the coverage of such Mortgage Loan by the related Primary
      Mortgage Insurance Policy, if any, will not be affected, or (ii) extend the
      due
      dates for Monthly Payments due on a Mortgage Note for a period of not greater
      than 180 days; provided that any extension pursuant to clause (ii) above shall
      not affect the amortization schedule of any Mortgage Loan for purposes of any
      computation hereunder, except as provided below. In the event of any such
      arrangement pursuant to clause (ii) above, the Master Servicer shall make timely
      advances on such Mortgage Loan during such extension pursuant to Section 4.03
      and in accordance with the amortization schedule of such Mortgage Loan without
      modification thereof by reason of such arrangements. Notwithstanding the
      foregoing, in the event that any Mortgage Loan is in default or, in the judgment
      of the Master Servicer, such default is reasonably foreseeable, the Master
      Servicer, consistent with the standards set forth in Section 3.01,
      may  waive, modify or vary any term of such Mortgage Loan (including
      modifications that change the Mortgage Rate, forgive the payment of principal
      or
      interest or extend the final maturity date of such Mortgage Loan), accept
      payment from the related Mortgagor of an amount less than the Stated Principal
      Balance in final satisfaction of such Mortgage Loan (such payment, a “Short
      Pay-off”) or consent to the postponement of strict compliance with any such term
      or otherwise grant indulgence to any Mortgagor, if in the Master Servicer’s
      determination such waiver, modification, postponement or indulgence is not
      materially adverse to the interests of the Certificateholders (taking into
      account any estimated Realized Loss that might result absent such
      action).

    In
      those
      cases where a Sub-Servicer is servicing a Mortgage Loan pursuant to a
      Sub-Servicing Agreement, the Sub-Servicer will be required to establish and
      maintain one or more accounts (collectively, the “Sub-Servicing Account”). The
      Sub-Servicing Account shall be an Eligible Account and shall comply with all
      requirements of this Agreement relating to the Collection Account (provided,
      however, that in the case of each Initial Sub-Servicing Agreement, the
      applicable Sub-Servicing Account shall comply with all requirements of the
      Initial Sub-Servicing Agreement relating to the custodial account provided
      for
      therein). The Sub-Servicer shall deposit in the clearing account (which account
      must be an Eligible Account) in which it customarily deposits payments and
      collections on mortgage loans in connection with its mortgage loan servicing
      activities on a daily basis, and in no event more than two Business Days after
      the Sub-Servicer’s receipt thereof, all proceeds of Mortgage Loans received by
      the Sub-Servicer less its servicing compensation to the extent permitted by
      the
      Sub-Servicing Agreement, and shall thereafter deposit such amounts in the
      Sub-Servicing Account, in no event more than one Business Day after the deposit
      of such funds into the clearing account. The Sub-Servicer shall thereafter
      remit
      such proceeds to the Master Servicer for deposit in the Collection Account
      not
      later than two Business Days after the deposit of such amounts in the
      Sub-Servicing Account (or, in the case of the Initial Sub-Servicing Agreement,
      at such time as is required pursuant to the terms of the Initial Sub-Servicing
      Agreement). For purposes of this Agreement, the Master Servicer shall be deemed
      to have received payments on the Mortgage Loans when the Sub-Servicer receives
      such payments.

                Accounts.

            


    

     

    The
      Master Servicer shall establish and maintain (or cause a Sub-Servicer to
      establish and maintain) one or more accounts (the “Servicing Accounts”), into
      which all collections from the Mortgagors (or related advances from
      Sub-Servicers) for the payment of ground rents, taxes, assessments, fire and
      hazard insurance premiums, Primary Mortgage Insurance Premiums, water charges,
      sewer rents and comparable items for the account of the Mortgagors (“Escrow
      Payments”) shall be deposited and retained. Servicing Accounts shall be Eligible
      Accounts. The Master Servicer (or the applicable Sub-Servicer) shall deposit
      in
      the clearing account (which account must be an Eligible Account) in which it
      customarily deposits payments and collections on mortgage loans in connection
      with its mortgage loan servicing activities on a daily basis, and in no event
      more than two Business Days after the Master Servicer’s (or the applicable
      Sub-Servicer’s) receipt thereof, all Escrow Payments collected on account of the
      Mortgage Loans and shall thereafter deposit such Escrow Payments in the
      Servicing Accounts, in no event more than one Business Day after the deposit
      of
      such funds in the clearing account, for the purpose of effecting the payment
      of
      any such items as required under the terms of this Agreement. Withdrawals of
      amounts from a Servicing Account may be made only to (i) effect payment of
      Escrow Payments; (ii) reimburse the Master Servicer (or a Sub-Servicer to the
      extent provided in the related Sub-Servicing Agreement) out of related
      collections for any advances made pursuant to Section 3.01 (with respect to
      taxes and assessments) and Section 3.14 (with respect to hazard insurance);
      (iii) refund to Mortgagors any sums as may be determined to be overages; (iv)
      pay interest, if required and as described below, to Mortgagors on balances
      in
      the Servicing Account; (v) clear and terminate the Servicing Account at the
      termination of the Master Servicer’s obligations and responsibilities in respect
      of the Mortgage Loans under this Agreement in accordance with Article IX; or
      (vi) recover amounts deposited in error. As part of its servicing duties, the
      Master Servicer or Sub-Servicers shall pay to the Mortgagors interest on funds
      in Servicing Accounts, to the extent required by law and, to the extent that
      interest earned on funds in the Servicing Accounts is insufficient, to pay
      such
      interest from its or their own funds, without any reimbursement therefor. To
      the
      extent that a Mortgage does not provide for Escrow Payments, the Master Servicer
      shall determine whether any such payments are made by the Mortgagor in a manner
      and at a time that avoids the loss of the Mortgaged Property due to a tax sale
      or the foreclosure of a tax lien. The Master Servicer assumes full
      responsibility for the payment of all such bills and shall effect payments
      of
      all such bills irrespective of the Mortgagor’s faithful performance in the
      payment of same or the making of the Escrow Payments and shall make advances
      from its own funds to effect such payments.

    (a)  On
      behalf
      of the Trust Fund, the Master Servicer shall establish and maintain one or
      more
      separate, segregated trust accounts (such account or accounts, the “Collection
      Account”), held in trust for the benefit of the Trustee and the
      Certificateholders. On behalf of the Trust Fund, the Master Servicer shall
      deposit or cause to be deposited in the clearing account (which account must
      be
      an Eligible Account) in which it customarily deposits payments and collections
      on mortgage loans in connection with its mortgage loan servicing activities
      on a
      daily basis, and in no event more than two Business Days after the Master
      Servicer’s receipt thereof, and shall thereafter deposit in the Collection
      Account, in no event more than one Business Day after the deposit of such funds
      into the clearing account, as and when received or as otherwise required
      hereunder, the following payments and collections received or made by it from
      and after the Cut-off Date (other than in respect of principal or interest
      on
      the related Mortgage Loans due on or before the Cut-off Date), or payments
      (other than Principal Prepayments) received by it on or prior to the Cut-off
      Date but allocable to a Due Period subsequent thereto:

     

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

     

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

     

    (iii)  all
      Insurance Proceeds, Subsequent Recoveries and Liquidation Proceeds (other than
      proceeds collected in respect of any particular REO Property and amounts paid
      by
      the Master Servicer in connection with a purchase of Mortgage Loans and REO
      Properties pursuant to Section 9.01);

     

    (iv)  any
      amounts required to be deposited pursuant to Section 3.12 in connection with
      any
      losses realized on Permitted Investments with respect to funds held in the
      Collection Account;

     

    (v)  any
      amounts required to be deposited by the Master Servicer pursuant to the second
      paragraph of Section 3.14(a) in respect of any blanket policy
      deductibles;

     

    (vi)  all
      proceeds of any Mortgage Loan repurchased or purchased in accordance with
      Section 2.03 or Section 9.01;

     

    (vii)  all
      amounts required to be deposited in connection with shortfalls in principal
      amount of Qualified Substitute Mortgage Loans pursuant to Section
      2.03;

     

    (viii)  [reserved];
      and

     

    (ix)  [reserved].

     

    For
      purposes of the immediately preceding sentence, the Cut-off Date with respect
      to
      any Qualified Substitute Mortgage Loan shall be deemed to be the date of
      substitution.

     

    The
      foregoing requirements for deposit in the Collection Accounts shall be
      exclusive, it being understood and agreed that, without limiting the generality
      of the foregoing, payments in the nature of late payment charges or assumption
      fees need not be deposited by the Master Servicer in the Collection Account.
      In
      the event the Master Servicer shall deposit in the Collection Account any amount
      not required to be deposited therein, it may at any time withdraw such amount
      from the Collection Account, any provision herein to the contrary
      notwithstanding.

     

    (b)  On
      behalf
      of the Trust Fund, the Paying Agent on behalf of the Trust Administrator shall
      establish and maintain one or more separate, segregated trust accounts (such
      account or accounts, the “Distribution Account”), held in trust for the benefit
      of the Certificateholders. On behalf of the Trust Fund, the Master Servicer
      shall deliver to the Paying Agent in immediately available funds for deposit
      in
      the Distribution Account on or before 12:00 p.m. New York time (i) on the Master
      Servicer Remittance Date, that portion of the Group 1 Available Distribution
      Amount and the Group 2 Available Distribution Amount (calculated in each case
      without regard to the subtraction therefrom of any applicable lender-paid
      primary mortgage insurance premium described in clause (i)(a) of each definition
      thereof) for the related Distribution Date then on deposit in the Collection
      Account and (ii) on each Business Day as of the commencement of which the
      balance on deposit in the Collection Account exceeds $75,000 following any
      withdrawals pursuant to the next succeeding sentence, the amount of such excess,
      but only if the Collection Account constitutes an Eligible Account solely
      pursuant to clause (ii) of the definition of “Eligible Account.” If the balance
      on deposit in the Collection Account exceeds $75,000 as of the commencement
      of
      business on any Business Day and the Collection Account constitutes an Eligible
      Account solely pursuant to clause (ii) of the definition of “Eligible Account,”
the Master Servicer shall, on or before 12:00 p.m. New York time on such
      Business Day, withdraw from the Collection Account any and all amounts payable
      or reimbursable to the Depositor, the Master Servicer, the Trustee, the Trust
      Administrator, the Seller or any Sub-Servicer pursuant to Section 3.11 and
      shall
      pay such amounts to the Persons entitled thereto.

     

    (c)  Funds
      in
      the Collection Account and the Distribution Account may be invested in Permitted
      Investments in accordance with the provisions set forth in Section 3.12. The
      Master Servicer shall give notice to the Trustee, the Trust Administrator,
      the
      Paying Agent and the Depositor of the location of the Collection Account
      maintained by it when established and prior to any change thereof. The Paying
      Agent shall give notice to the Master Servicer, the Trust Administrator, the
      Paying Agent and the Depositor of the location of the Distribution Account
      when
      established and prior to any change thereof.

     

    (d)  Funds
      held in the Collection Account at any time may be delivered by the Master
      Servicer to the Paying Agent on behalf of the Trust Administrator for deposit
      in
      an account (which may be the Distribution Account and must satisfy the standards
      for the Distribution Account as set forth in the definition thereof) and for
      all
      purposes of this Agreement shall be deemed to be a part of the Collection
      Account; provided, however, that the Paying Agent shall have the sole authority
      to withdraw any funds held pursuant to this subsection (d). In the event the
      Master Servicer shall deliver to the Paying Agent for deposit in the
      Distribution Account any amount not required to be deposited therein, it may
      at
      any time request that the Paying Agent withdraw such amount from the
      Distribution Account and remit to it any such amount, any provision herein
      to
      the contrary notwithstanding. In addition, the Master Servicer shall deliver
      to
      the Paying Agent from time to time for deposit, and upon written notification
      from the Master Servicer, the Paying Agent shall so deposit, in the Distribution
      Account:

     

    (i)  any
      P&I Advances, as required pursuant to Section 4.03;

     

    (ii)  any
      amounts required to be deposited pursuant to Section 3.23(d) or (f) in
      connection with any REO Property;

     

    (iii)  any
      amounts to be paid by the Master Servicer in connection with a purchase of
      Mortgage Loans and REO Properties pursuant to Section 9.01;

     

    (iv)  any
      amounts required to be deposited pursuant to Section 3.24 in connection with
      any
      Prepayment Interest Shortfalls; and

     

    (v)  any
      Stayed Funds, as soon as permitted by the federal bankruptcy court having
      jurisdiction in such matters.

     

    (e)  Promptly
      upon receipt of any Stayed Funds, whether from the Master Servicer, a trustee
      in
      bankruptcy, or federal bankruptcy court or other source, the Paying Agent shall
      deposit such funds in the Distribution Account, subject to withdrawal thereof
      as
      permitted hereunder.

     

    (f)  The
      Master Servicer shall deposit in the Collection Account any amounts required
      to
      be deposited pursuant to Section 3.12(b) in connection with losses realized
      on
      Permitted Investments with respect to funds held in the Collection
      Account.

      pursuant to the first sentence of Section 3.10(d);

     

    (ii)  subject
      to Section 3.16(d), to reimburse the Master Servicer for P&I Advances, but
      only to the extent of amounts received which represent Late Collections (net
      of
      the related Servicing Fees) of Monthly Payments on Mortgage Loans with respect
      to which such P&I Advances were made in accordance with the provisions of

      unpaid Servicing Fees, (B) any unreimbursed Servicing Advances with respect
      to
      each Mortgage Loan, but only to the extent of any Liquidation Proceeds,
      Insurance Proceeds or other amounts as may be collected by the Master Servicer
      from a Mortgagor, or otherwise received with respect to such Mortgage Loan
      and
      (C) any nonrecoverable Servicing Advances following the final liquidation of
      a
      Mortgage Loan, but only to the extent that Late Collections,
      Liquidation  Proceeds and Insurance Proceeds received with respect to
      such Mortgage Loan are insufficient to reimburse the Master Servicer or any
      Sub-Servicer for such Servicing Advances;

      Fee)
      on the Master Servicer Remittance Date any interest or investment income earned
      on funds deposited in the Collection Account;

     

    (v)  to

      respect to each Mortgage Loan that has previously been purchased or replaced
      pursuant to Section 2.03 all amounts received thereon subsequent to the date
      of
      purchase or substitution, as the case may be;

     

    (vi)  to
      reimburse the Master Servicer for any P&I Advance previously made which the
      Master Servicer has determined to be a Nonrecoverable P&I Advance in
      accordance with the provisions of Section 4.03;

     

    (vii)  to
      reimburse the Master Servicer or the Depositor for expenses incurred by or
      reimbursable to the Master Servicer or the Depositor, as the case may be,
      pursuant to Section 6.03;

     

    (viii)  to

      case may be, for expenses reasonably incurred in respect of the breach or defect
      giving rise to the purchase obligation under Section 2.03 or Section 2.04 of
      this Agreement that were included in the Purchase Price of the Mortgage Loan,
      including any  expenses arising out of the enforcement of the purchase
      obligation;

      Collection Account, to the extent held by or on behalf of it, pursuant to
      subclauses (ii), (iii), (iv), (v), (vi), (viii) and (ix) above. The Master

      made in the name of the Trust Administrator (in its capacity as such) or in
      the

                then
                payable thereunder and (2) the amount required to be withdrawn on

                Responsible Officer of the Trust Administrator that such Permitted
                Investment would not constitute a Permitted Investment in respect

      accordance with Section 3.11. The Master Servicer shall deposit in the
      Collection Account the amount of any loss of principal incurred in respect
      of
      any such Permitted Investment made with funds in such accounts immediately
      upon
      realization of such loss.

     

    (c)  All

      The Paying Agent shall deposit in the Distribution Account the amount of any
      loss of principal incurred in respect of any such Permitted Investment made
      with
      funds in such accounts immediately upon realization of such loss.

     

    (d)  Except
      as
      otherwise expressly provided in this Agreement, if any default occurs in the

      in any other performance required under any Permitted Investment, the Trustee
      may and, subject to Section 8.01 and Section 8.02(a)(v), upon the request of
      the
      Holders of Certificates representing more than 50% of the Voting Rights
      allocated to any Class of Certificates, shall take such action as may be
      appropriate to enforce such payment or performance, including the institution
      and prosecution of appropriate proceedings.

    The
      Master Servicer will maintain or cause the related Sub-Servicer, if any, to
      maintain in full force and effect, if required under the Mortgage Loan Purchase
      Agreement and to the extent available, a Primary Mortgage Insurance Policy
      with
      respect to each Mortgage Loan so insured as of the Closing Date (or, in the
      case
      of a Qualified Substitute Mortgage Loan, on the date of substitution). Such
      coverage will be maintained with respect to each such Mortgage Loan for so
      long
      as it is outstanding, subject to any applicable laws or until the related
      Loan-to-Value Ratio is reduced to less than or equal to 80% based on Mortgagor
      payments. The Master Servicer shall cause the premium for each Primary Mortgage
      Insurance Policy to be paid on a timely basis and shall pay such premium out
      of
      its own funds if it is not otherwise paid. The Master Servicer or the related
      Sub-Servicer, if any, will not cancel or refuse to renew any such Primary
      Mortgage Insurance Policy in effect on the Closing Date (or, in the case of
      a
      Qualified Substitute Mortgage Loan, on the date of substitution) that is
      required to be kept in force under this Agreement unless a replacement Primary
      Mortgage Insurance Policy for such canceled or non-renewed policy is obtained
      from and maintained with a Qualified Insurer.

     

    The
      Master Servicer shall not take, or permit any Sub-Servicer to take, any action
      which would result in non-coverage under any applicable Primary Mortgage
      Insurance Policy of any loss which, but for the actions of the Master Servicer
      or Sub-Servicer, would have been covered thereunder. The Master Servicer will
      comply in the performance of this Agreement with all reasonable rules and
      requirements of each insurer under each Primary Mortgage Insurance Policy.
      In
      connection with any assumption and modification agreement or substitution of
      liability agreement entered into or to be entered into pursuant to Section
      3.15,
      the Master Servicer shall promptly notify the insurer under the related Primary
      Mortgage Insurance Policy, if any, of such assumption in accordance with the
      terms of such policies and shall take all actions which may be required by
      such
      insurer as a condition to the continuation of coverage under the Primary
      Mortgage Insurance Policy. If any such Primary Mortgage Insurance Policy is
      terminated as a result of such assumption, the Master Servicer or the related
      Sub-Servicer shall obtain a replacement Primary Mortgage Insurance Policy as
      provided above.

     

    In
      connection with its activities as administrator and servicer of the Mortgage
      Loans, the Master Servicer agrees to prepare and present, on behalf of itself,
      the Trustee and the Certificateholders, claims to the insurer under any Primary
      Mortgage Insurance Policy in a timely fashion in accordance with the terms
      of
      such policies and, in this regard, to take such action as shall be necessary
      to
      permit recovery under any Primary Mortgage Insurance Policy respecting a
      defaulted Mortgage Loan. Any amounts collected by the Master Servicer under
      any
      Primary Mortgage Insurance Policy shall be deposited in the Collection Account,
      subject to withdrawal pursuant to Section 3.11; and any amounts collected by
      the
      Master Servicer under any Primary Mortgage Insurance Policy in respect of any
      REO Property shall be deposited in the Collection Account, subject to withdrawal
      pursuant to Section 3.23. In those cases in which a Mortgage Loan is serviced
      by
      a Sub-Servicer, the Sub-Servicer, on behalf of itself, the Trustee, and the
      Certificateholders, will present claims to the insurer under any Primary
      Mortgage Insurance Policy and all collections thereunder shall be deposited
      initially in the Sub-Servicing Account.

    (a)  The
      Master Servicer shall cause to be maintained for each Mortgage Loan fire
      insurance with extended coverage on the related Mortgaged Property in an amount
      which is at least equal to the least of (i) the current principal balance of
      such Mortgage Loan, (ii) the amount necessary to fully compensate for any damage
      or loss to the improvements that are a part of such property on a replacement
      cost basis and (iii) the maximum insurable value of the improvements which
      are a
      part of such Mortgaged Property, in each case in an amount not less than such
      amount as is necessary to avoid the application of any coinsurance clause
      contained in the related hazard insurance policy. The Master Servicer shall
      also
      cause to be maintained fire insurance with extended coverage on each REO
      Property in an amount which is at least equal to the lesser of (i) the maximum
      insurable value of the improvements which are a part of such property and (ii)
      the outstanding principal balance of the related Mortgage Loan at the time
      it
      became an REO Property, plus accrued interest at the Mortgage Rate and related
      Servicing Advances. The Master Servicer will comply in the performance of this
      Agreement with all reasonable rules and requirements of each insurer under
      any
      such hazard policies. Any amounts to be collected by the Master Servicer under
      any such policies (other than amounts to be applied to the restoration or repair
      of the property subject to the related Mortgage or amounts to be released to
      the
      Mortgagor in accordance with the procedures that the Master Servicer would
      follow in servicing loans held for its own account, subject to the terms and
      conditions of the related Mortgage and Mortgage Note) shall be deposited in
      the
      Collection Account, subject to withdrawal pursuant to Section 3.11, if received
      in respect of a Mortgage Loan, or in the REO Account, subject to withdrawal
      pursuant to Section 3.23, if received in respect of an REO Property. Any cost
      incurred by the Master Servicer in maintaining any such insurance shall not,
      for
      the purpose of calculating distributions to Certificateholders, be added to
      the
      unpaid principal balance of the related Mortgage Loan, notwithstanding that
      the
      terms of such Mortgage Loan so permit. It is understood and agreed that no
      earthquake or other additional insurance is to be required of any Mortgagor
      other than pursuant to such applicable laws and regulations as shall at any
      time
      be in force and as shall require such additional insurance. If the Mortgaged
      Property or REO Property is at any time in an area identified in the Federal
      Register by the Federal Emergency Management Agency as having special flood
      hazards, the Master Servicer will cause to be maintained a flood insurance
      policy in respect thereof. Such flood insurance shall be in an amount equal
      to
      the lesser of (i) the unpaid principal balance of the related Mortgage Loan
      and
      (ii) the maximum amount of such insurance available for the related Mortgaged
      Property under the national flood insurance program (assuming that the area
      in
      which such Mortgaged Property is located is participating in such
      program).

     

    In
      the
      event that the Master Servicer shall obtain and maintain a blanket policy with
      an insurer having a General Policy Rating of A:X or better in Best’s Key Rating
      Guide (or such other rating that is comparable to such rating) insuring against
      hazard losses on all of the Mortgage Loans, it shall conclusively be deemed
      to
      have satisfied its obligations as set forth in the first two sentences of this
      Section 3.14, it being understood and agreed that such policy may contain a
      deductible clause, in which case the Master Servicer shall, in the event that
      there shall not have been maintained on the related Mortgaged Property or REO
      Property a policy complying with the first two sentences of this Section 3.14,
      and there shall have been one or more losses which would have been covered
      by
      such policy, deposit to the Collection Account from its own funds the amount
      not
      otherwise payable under the blanket policy because of such deductible clause.
      In
      connection with its activities as administrator and servicer of the Mortgage
      Loans, the Master Servicer agrees to prepare and present, on behalf of itself,
      the Trustee and the Certificateholders, claims under any such blanket policy
      in
      a timely fashion in accordance with the terms of such policy.

     

    (b)  The
      Master Servicer shall keep in force during the term of this Agreement a policy
      or policies of insurance covering errors and omissions for failure in the
      performance of the Master Servicer’s obligations under this Agreement, which
      policy or policies shall be in such form and amount that would meet the
      requirements of Fannie Mae or Freddie Mac if it were the purchaser of the
      Mortgage Loans, unless the Master Servicer has obtained a waiver of such
      requirements from Fannie Mae or Freddie Mac. The Master Servicer shall also
      maintain a fidelity bond in the form and amount that would meet the requirements
      of Fannie Mae or Freddie Mac, unless the Master Servicer has obtained a waiver
      of such requirements from Fannie Mae or Freddie Mac. The Master Servicer shall
      provide the Trustee and the Paying Agent (upon the Trustee’s or Paying Agent’s
      reasonable request) with copies of any such insurance policies and fidelity
      bond. The Master Servicer shall be deemed to have complied with this provision
      if an Affiliate of the Master Servicer has such errors and omissions and
      fidelity bond coverage and, by the terms of such insurance policy or fidelity
      bond, the coverage afforded thereunder extends to the Master Servicer. Any
      such
      errors and omissions policy and fidelity bond shall by its terms not be
      cancelable without thirty days’ prior written notice to the Trustee. The Master
      Servicer shall also cause each Sub-Servicer to maintain a policy of insurance
      covering errors and omissions and a fidelity bond which would meet such
      requirements.

    The
      Master Servicer will, to the extent it has knowledge of any conveyance or
      prospective conveyance of any Mortgaged Property by any Mortgagor (whether
      by
      absolute conveyance or by contract of sale, and whether or not the Mortgagor
      remains or is to remain liable under the Mortgage Note and/or the Mortgage),
      exercise its rights to accelerate the maturity of such Mortgage Loan under
      the
“due-on-sale” clause, if any, applicable thereto; provided, however, that the
      Master Servicer shall not exercise any such rights if prohibited by law from
      doing so or if the exercise of such rights would impair or threaten to impair
      any recovery under the related Primary Mortgage Insurance Policy, if any. If
      the
      Master Servicer reasonably believes it is unable under applicable law to enforce
      such “due-on-sale” clause, or if any of the other conditions set forth in the
      proviso to the preceding sentence apply, the Master Servicer will enter into
      an
      assumption and modification agreement from or with the person to whom such
      property has been conveyed or is proposed to be conveyed, pursuant to which
      such
      person becomes liable under the Mortgage Note and, to the extent permitted
      by
      applicable state law, the Mortgagor remains liable thereon. The Master Servicer
      is also authorized to enter into a substitution of liability agreement with
      such
      person, pursuant to which the original Mortgagor is released from liability
      and
      such person is substituted as the Mortgagor and becomes liable under the
      Mortgage Note, provided that no such substitution shall be effective unless
      such
      person satisfies the underwriting criteria of the Master Servicer. In connection
      with any assumption or substitution, the Master Servicer shall apply such
      underwriting standards and follow such practices and procedures as shall be
      normal and usual in its general mortgage servicing activities and as it applies
      to other mortgage loans owned solely by it. The Master Servicer shall not take
      or enter into any assumption and modification agreement, however, unless (to
      the
      extent practicable in the circumstances) it shall have received confirmation,
      in
      writing, of the continued effectiveness of any applicable Primary Mortgage
      Insurance Policy or hazard insurance policy, or a new policy meeting the
      requirements of this Section is obtained. Any fee collected by the Master
      Servicer in respect of an assumption or substitution of liability agreement
      will
      be retained by the Master Servicer as additional servicing compensation. In
      connection with any such assumption, no material term of the Mortgage Note
      (including but not limited to the related Mortgage Rate and the amount of the
      Monthly Payment) may be amended or modified, except as otherwise required
      pursuant to the terms thereof. The Master Servicer shall notify the Trustee
      that
      any such substitution or assumption agreement has been completed by forwarding
      to the respective Custodian (with a copy to the Trustee) the executed original
      of such substitution or assumption agreement, which document shall be added
      to
      the related Mortgage File and shall, for all purposes, be considered a part
      of
      such Mortgage File to the same extent as all other documents and instruments
      constituting a part thereof.

     

    Notwithstanding
      the foregoing paragraph or any other provision of this Agreement, the Master
      Servicer shall not be deemed to be in default, breach or any other violation
      of
      its obligations hereunder by reason of any assumption of a Mortgage Loan by
      operation of law or by the terms of the Mortgage Note or any assumption which
      the Master Servicer may be restricted by law from preventing, for any reason
      whatever. For purposes of this Section 3.15, the term “assumption” is deemed to
      also include a sale (of the Mortgaged Property) subject to the Mortgage that
      is
      not accompanied by an assumption or substitution of liability
      agreement.

    (a)  The
      Master Servicer shall, consistent with the servicing standard set forth in
      Section 3.01, foreclose upon or otherwise comparably convert the ownership
      of
      properties securing such of the Mortgage Loans as come into and continue in
      default and as to which no satisfactory arrangements can be made for collection
      of delinquent payments pursuant to Section 3.07. The Master Servicer shall
      be
      responsible for all costs and expenses incurred by it in any such proceedings;
      provided, however, that such costs and expenses will be recoverable as Servicing
      Advances by the Master Servicer as contemplated in Section 3.11 and Section
      3.23. The foregoing is subject to the provision that, in any case in which
      Mortgaged Property shall have suffered damage from an Uninsured Cause, the
      Master Servicer shall not be required to expend its own funds toward the
      restoration of such property unless it shall determine in its discretion that
      such restoration will increase the proceeds of liquidation of the related
      Mortgage Loan after reimbursement to itself for such expenses.

     

    (b)  Notwithstanding
      the foregoing provisions of this Section 3.16 or any other provision of this
      Agreement, with respect to any Mortgage Loan as to which the Master Servicer
      has
      received actual notice of, or has actual knowledge of, the presence of any
      toxic
      or hazardous substance on the related Mortgaged Property, the Master Servicer
      shall not, on behalf of the Trustee, either (i) obtain title to such Mortgaged
      Property as a result of or in lieu of foreclosure or otherwise, or (ii)
      otherwise acquire possession of, or take any other action with respect to,
      such
      Mortgaged Property, if, as a result of any such action, the Trustee, the Trust
      Fund, the Trust Administrator, the Master Servicer or the Certificateholders
      would be considered to hold title to, to be a “mortgagee-in- possession” of, or
      to be an “owner” or “operator” of such Mortgaged Property within the meaning of
      the Comprehensive Environmental Response, Compensation and Liability Act of
      1980, as amended from time to time, or any comparable law, unless the Master
      Servicer has also previously determined, based on its reasonable judgment and
      a
      report prepared by a Person who regularly conducts environmental audits using
      customary industry standards, that:

     

    (1)  such
      Mortgaged Property is in compliance with applicable environmental laws or,
      if
      not, that it would be in the best economic interest of the Trust Fund to take
      such actions as are necessary to bring the Mortgaged Property into compliance
      therewith; and

     

    (2)  there
      are
      no circumstances present at such Mortgaged Property relating to the use,
      management or disposal of any hazardous substances, hazardous materials,
      hazardous wastes, or petroleum-based materials for which investigation, testing,
      monitoring, containment, clean-up or remediation could be required under any
      federal, state or local law or regulation, or that if any such materials are
      present for which such action could be required, that it would be in the best
      economic interest of the Trust Fund to take such actions with respect to the
      affected Mortgaged Property.

     

    The
      cost
      of the environmental audit report contemplated by this Section 3.23 shall be
      advanced by the Master Servicer, subject to the Master Servicer’s right to be
      reimbursed therefor from the Collection Account as provided in Section
      3.11(a)(ix), such right of reimbursement being prior to the rights of
      Certificateholders to receive any amount in the Collection Account received
      in
      respect of the affected Mortgage Loan or other Mortgage Loans.

     

    If
      the
      Master Servicer determines, as described above, that it is in the best economic
      interest of the Trust Fund to take such actions as are necessary to bring any
      such Mortgaged Property into compliance with applicable environmental laws,
      or
      to take such action with respect to the containment, clean-up or remediation
      of
      hazardous substances, hazardous materials, hazardous wastes or petroleum-based
      materials affecting any such Mortgaged Property, then the Master Servicer shall
      take such action as it deems to be in the best economic interest of the Trust
      Fund. The cost of any such compliance, containment, cleanup or remediation
      shall
      be advanced by the Master Servicer, subject to the Master Servicer’s right to be
      reimbursed therefor from the Collection Account as provided in Section
      3.11(a)(ix), such right of reimbursement being prior to the rights of
      Certificateholders to receive any amount in the Collection Account received
      in
      respect of the affected Mortgage Loan or other Mortgage Loans.

     

    (c)  The
      Master Servicer shall have the right to purchase from the Trust Fund any
      defaulted Mortgage Loan that is 90 days or more delinquent, which the Master
      Servicer determines in good faith will otherwise become subject to foreclosure
      proceedings (evidence of such determination to be delivered in writing to the
      Trustee and the Trust Administrator, in form and substance satisfactory to
      the
      Trustee and the Trust Administrator prior to purchase), at a price equal to
      the
      Purchase Price. The Purchase Price for any Mortgage Loan purchased hereunder
      shall be deposited in the Collection Account, and the Trustee (or a Custodian
      on
      behalf of the Trustee), upon receipt of written certification from the Master
      Servicer of such deposit, shall release or cause to be released to the Master
      Servicer the related Mortgage File and the Trustee (or a Custodian on behalf
      of
      the Trustee), upon receipt of written certification from the Master Servicer
      of
      such deposit, shall execute and deliver such instruments of transfer or
      assignment, in each case without recourse, as the Master Servicer shall furnish
      and as shall be necessary to vest in the Master Servicer title to any Mortgage
      Loan released pursuant hereto.

     

    (d)  Proceeds
      received in connection with any Final Recovery Determination, as well as any
      recovery resulting from a partial collection of Insurance Proceeds or
      Liquidation Proceeds, in respect of any Mortgage Loan, will be applied in the
      following order of priority: first, to reimburse the Master Servicer or any
      Sub-Servicer for any related unreimbursed Servicing Advances and P&I
      Advances, pursuant to Section 3.11(a)(ii) or (a)(iii)(B); second, to accrued
      and
      unpaid interest on the Mortgage Loan, to the date of the Final Recovery
      Determination, or to the Due Date prior to the Distribution Date on which such
      amounts are to be distributed if not in connection with a Final Recovery
      Determination; and third, as a recovery of principal of the Mortgage Loan.
      If
      the amount of the recovery so allocated to interest is less than the full amount
      of accrued and unpaid interest due on such Mortgage Loan, the amount of such
      recovery will be allocated by the Master Servicer as follows: first, to unpaid
      Servicing Fees; and second, to the balance of the interest then due and owing.
      The portion of the recovery so allocated to unpaid Servicing Fees shall be
      reimbursed to the Master Servicer or any Sub-Servicer pursuant to Section
      3.11(a)(iii)(A).

      respective Custodian, on behalf of the Trustee, deliver to it the Mortgage
      File.
      Upon receipt of such certification and request, the respective Custodian, on
      behalf of the Trustee, shall promptly release the related Mortgage File to
      the
      Master Servicer, and the Master Servicer is authorized to cause the removal
      from
      the registration on the MERS® System of any such Mortgage, if applicable, and to
      execute and deliver, on behalf of the Trustee and the Certificateholders or
      any
      of them, any and all instruments of satisfaction or cancellation or of partial
      or full release. No expenses incurred in connection with any instrument of
      satisfaction or deed of reconveyance shall be chargeable to the Collection
      Account or the Distribution Account.

     

    The
      Trustee (or a Custodian on its behalf) shall, at the written request and expense
      of any Certificateholder, provide a written report to such Certificateholder
      of
      all Mortgage Files released to the Master Servicer for servicing
      purposes.

     

    (b)  From
      time
      to time and as appropriate for the servicing or foreclosure of any Mortgage
      Loan, including, for this purpose, collection under any Primary Mortgage
      Insurance Policy or any other insurance policy relating to the Mortgage Loans,
      the respective Custodian, on behalf of the Trustee, shall, upon request of
      the
      Master Servicer and delivery to the respective Custodian and the Trustee of
      a
      Request for Release in the form of Exhibit E-l, release the related Mortgage
      File to the Master Servicer, and the respective Custodian, on behalf of the
      Trustee, shall, at the direction of the Master Servicer, execute such documents
      as shall be necessary to the prosecution of any such proceedings. Such Request
      for Release shall obligate the Master Servicer to return each and every document
      previously requested from the Mortgage File to the respective Custodian when
      the
      need therefor by the Master Servicer no longer exists, unless the Mortgage
      Loan
      has been liquidated and the Liquidation Proceeds relating to the Mortgage Loan
      have been deposited in the Collection Account or the Mortgage File or such
      document has been delivered to an attorney, or to a public trustee or other
      public official as required by law, for purposes of initiating or pursuing
      legal
      action or other proceedings for the foreclosure of the Mortgaged Property either
      judicially or non-judicially, and the Master Servicer has delivered to the
      respective Custodian, on behalf of the Trustee, a certificate of a Servicing
      Officer certifying as to the name and address of the Person to which such
      Mortgage File or such document was delivered and the purpose or purposes of
      such
      delivery. Upon receipt of a certificate of a Servicing Officer stating that
      such
      Mortgage Loan was liquidated and that all amounts received or to be received
      in
      connection with such liquidation that are required to be deposited into the
      Collection Account have been so deposited, or that such Mortgage Loan has become
      an REO Property, a copy of the Request for Release shall be released by the
      respective Custodian, on behalf of the Trustee, to the Master
      Servicer.

     

    (c)  Upon
      written certification of a Servicing Officer, the Trustee shall execute and
      deliver to the Master Servicer any court pleadings, requests for trustee’s sale
      or other documents reasonably necessary to the foreclosure or trustee’s sale in
      respect of a Mortgaged Property or to any legal action brought to obtain
      judgment against any Mortgagor on the Mortgage Note or Mortgage or to obtain
      a
      deficiency judgment, or to enforce any other remedies or rights provided by
      the
      Mortgage Note or Mortgage or otherwise available at law or in equity. Each
      such
      certification shall include a request that such pleadings or documents be
      executed by the Trustee and a statement as to the reason such documents or
      pleadings are required and that the execution and delivery thereof by the
      Trustee will not invalidate or otherwise affect the lien of the Mortgage, except
      for the termination of such a lien upon completion of the foreclosure or
      trustee’s sale.

      3.23(b) to withdraw from any REO Account, as additional servicing compensation,
      interest or other income earned on deposits therein, subject to Section 3.12

      due under any Primary Insurance Policies, if applicable, premiums for the
      insurance required by Section 3.14, to the extent such premiums are not paid

      on
      or before March 15th of each
      calendar
      year beginning in 2008, an Officers’ Certificate (an “Annual Statement of
      Compliance”) stating, as to each signatory thereof, that (i) a review of the
      activities of the  Master Servicer during the preceding calendar year
      and of performance under this Agreement has been made under such officers’
supervision and (ii) to the best of such officers’ knowledge, based on such
      review, the Master Servicer has fulfilled all of its obligations under this
      Agreement in all material respects throughout such year, or, if there has been
      a
      failure to fulfill any such obligation in any material respect, specifying
      each
      such failure known to such officer and the nature and status of cure provisions

    Failure
      of the Master Servicer to comply with this Section 3.20 shall be deemed a Master

      shall, in addition to whatever rights the Trustee may have under this Agreement

    (a)  The
      Master Servicer shall service and administer the Mortgage Loans in accordance
      with all applicable requirements of the Servicing Criteria (as set forth in
      Exhibit C hereto).  The Master Servicer shall deliver to the Depositor
      and the Trust Administrator or cause to be delivered to the Depositor and the
      Trust Administrator, on or before March 1st of each
      calendar
      year beginning in 2008, the following:

     

    (i)  a
      report
      (an “Assessment of Compliance”) regarding the Master Servicer’s assessment of
      compliance with the Servicing Criteria during the immediately preceding calendar
      year, as required under Rules 13a-18 and 15d-18 of the Exchange Act and Item
      1122 of Regulation AB.  Such report shall be signed by an authorized
      officer of the Master Servicer, and shall address each of the Servicing Criteria
      set forth in Exhibit C hereto;

     

    (ii)  a
      report
      (an “Attestation Report”) of a registered public accounting firm reasonably
      acceptable to the Depositor that attests to, and reports on, the assessment
      of
      compliance made by the Master Servicer and delivered pursuant to the preceding
      paragraph.  Such attestation shall be in accordance with Rules
      1-02(a)(3) and 2-02(g) of Regulation S-X under the Securities Act and the
      Exchange Act;

     

    (iii)  from
      each
      Sub-Servicer, and each subcontractor determined by the Master Servicer to be
      “participating in the servicing function” within the meaning of Item 1122 of
      Regulation AB, an Assessment of Compliance and Attestation Report as and when
      provided in paragraphs (i) and (ii) of this Section 3.21(a); and

     

    (iv)  a
      statement as to which of the Servicing Criteria, if any, are not applicable
      to
      the Master Servicer, which statement shall be based on the activities it
      performs with respect to Mortgage-Pass Through securities transactions taken
      as
      a whole involving the Master Servicer, that are backed by the same asset type
      as
      the Mortgage Loans.

     

    (b)  As
      provided in 3.21(a)(iii) above, the Master Servicer shall, or shall cause any
      Sub-Servicer and each subcontractor determined by the Master Servicer to be
      “participating in the servicing function” within the meaning of Item 1122 of
      Regulation AB to, deliver to the Trust Administrator and the Depositor an
      Assessment of Compliance and Attestation Report as and when provided
      above.

     

    Such
      Assessment of Compliance, as to any Sub-Servicer, shall at a minimum address
      each of the Servicing Criteria specified on Exhibit C hereto which are indicated
      as applicable to any “primary servicer.”  Notwithstanding the
      foregoing, as to any subcontractor, an Assessment of Compliance is not required
      to be delivered unless it is required as part of a Form 10-K with respect to
      the
      Trust Fund.

     

    If
      the
      Master Servicer cannot deliver any Assessment of Compliance or Attestation
      Report by March 1st of such
      year, the
      Trustee, at the direction of the Depositor, may permit a cure period for the
      Master Servicer to deliver such Assessment of Compliance or Attestation Report,
      but in no event later than March 15th of such
      year.

     

    Failure
      of the Master Servicer to timely comply with this Section 3.21 shall be deemed
      a
      Master Servicer Event of Default, and upon the receipt of written notice from
      the Trustee of such Event of Default, the Trustee at the direction of the
      Depositor may, in addition to whatever rights the Trustee may have under this
      Agreement and at law or equity or to damages, including injunctive relief and
      specific performance, upon notice immediately terminate all the rights and
      obligations of the Master Servicer under this Agreement and in and to the
      Mortgage Loans and the proceeds thereof without compensating the Master Servicer
      for the same.  This paragraph shall supersede any other provision in
      this Agreement or any other agreement to the contrary.

     

    The
      Trust
      Administrator shall also provide an Assessment of Compliance and Attestation
      Report, as and when provided above, which shall at a minimum address each of
      the
      Servicing Criteria specified on Exhibit C hereto which are indicated as
      applicable to the Trust Administrator.  The Paying Agent, Certificate
      Registrar and Authenticating Agent shall also provide an Assessment of
      Compliance and Attestation Report, as and when provided above, which shall
      at a
      minimum address each of the Servicing Criteria specified on Exhibit C hereto
      which are indicated as applicable to the Paying Agent, Certificate Registrar
      and
      Authenticating Agent.  The Master Servicer shall on behalf of the
      Trustee enforce the obligations of each Custodian under the applicable Custodial
      Agreement to provide an Assessment of Compliance and Attestation Report, as,
      when and to the extent set forth in the applicable Custodial
      Agreement.

     

    The
      Master Servicer shall indemnify and hold harmless the Depositor and its
      officers, directors and Affiliates from and against any actual losses, damages,
      penalties, fines, forfeitures, reasonable and necessary legal fees and related
      costs, judgments and other costs and expenses that such Person may sustain
      based
      upon a breach of the Master Servicer’s obligations, as applicable, under this
      Section 3.21.  The Trust Administrator shall indemnify and hold
      harmless the Depositor and its officers, directors and Affiliates from and
      against any actual losses, damages, penalties, fines, forfeitures, reasonable
      and necessary legal fees and related costs, judgments and other costs and

      Administrator to deliver when required its Assessment of Compliance and

                Property.

            


    

     

    (a)  The
      deed
      or certificate of sale of any REO Property shall be taken in the name of the
      Trustee, or its nominee, in trust for the benefit of the Certificateholders.
      The
      Master Servicer, on behalf of the Trust Fund, shall either sell any REO Property
      before the close of the third taxable year following the year the Trust Fund
      acquires ownership of such REO Property for purposes of Section 860G(a)(8)
      of
      the Code or request from the Internal Revenue Service, no later than 60 days
      before the day on which the above three-year grace period would otherwise
      expire, an extension of the above three-year grace period, unless the Master
      Servicer shall have delivered to the Trustee, the Trust Administrator and the
      Depositor an Opinion of Counsel, addressed to the Trustee, the Trust
      Administrator and the Depositor, to the effect that the holding by the Trust
      Fund of such REO Property subsequent to the close of the third taxable year
      after its acquisition will not result in the imposition on the Trust Fund of
      taxes on “prohibited transactions” thereof, as defined in Section 860F of the
      Code, or cause any Trust REMIC to fail to qualify as a REMIC under Federal
      law
      at any time that any Certificates are outstanding. The Master Servicer shall
      manage, conserve, protect and operate each REO Property for the
      Certificateholders solely for the purpose of its prompt disposition and sale
      in
      a manner which does not cause such REO Property to fail to qualify as
“foreclosure property” within the meaning of Section 860G(a)(8) of the Code or
      result in the receipt by any Trust REMIC of any “income from non-permitted
      assets” within the meaning of Section 860F(a)(2)(B) of the Code, or any “net
      income from foreclosure property” which is subject to taxation under the REMIC
      Provisions.

     

    (b)  The
      Master Servicer shall segregate and hold all funds collected and received in
      connection with the operation of any REO Property separate and apart from its
      own funds and general assets and shall establish and maintain with respect
      to
      REO Properties an account held in trust for the Trustee for the benefit of
      the
      Certificateholders (the “REO Account”), which shall be an Eligible Account. The
      Master Servicer shall be permitted to allow the Collection Account to serve
      as
      the REO Account, subject to separate ledgers for each REO Property. The Master
      Servicer shall be entitled to retain or withdraw any interest income paid on
      funds deposited in the REO Account.

     

    (c)  The
      Master Servicer shall have full power and authority, subject only to the
      specific requirements and prohibitions of this Agreement, to do any and all
      things in connection with any REO Property as are consistent with the manner
      in
      which the Master Servicer manages and operates similar property owned by the
      Master Servicer or any of its Affiliates, all on such terms and for such period
      as the Master Servicer deems to be in the best interests of Certificateholders.
      In connection therewith, the Master Servicer shall deposit, or cause to be
      deposited in the clearing account (which account must be an Eligible Account)
      in
      which it customarily deposits payments and collections on mortgage loans in
      connection with its mortgage loan servicing activities on a daily basis, and
      in
      no event more than two Business Days after the Master Servicer’s receipt
      thereof, and shall thereafter deposit in the REO Account, in no event more
      than
      one Business Day after the deposit of such funds into the clearing account,
      all
      revenues received by it with respect to an REO Property and shall withdraw
      therefrom funds necessary for the proper operation, management and maintenance
      of such REO Property including, without limitation:

     

    (i)  all
      insurance premiums due and payable in respect of such REO Property;

     

    (ii)  all
      real
      estate taxes and assessments in respect of such REO Property that may result
      in
      the imposition of a lien thereon; and

     

    (iii)  all
      costs
      and expenses necessary to maintain such REO Property.

     

    To
      the
      extent that amounts on deposit in the REO Account with respect to an REO
      Property are insufficient for the purposes set forth in clauses (i) through
      (iii) above with respect to such REO Property, the Master Servicer shall advance
      from its own funds such amount as is necessary for such purposes if, but only
      if, the Master Servicer would make such advances if the Master Servicer owned
      the REO Property and if in the Master Servicer’s judgment, the payment of such
      amounts will be recoverable from the rental or sale of the REO
      Property.

     

    Notwithstanding
      the foregoing, none of the Master Servicer, the Trust Administrator or the
      Trustee shall:

     

    (i)  authorize
      the Trust Fund to enter into, renew or extend any New Lease with respect to
      any
      REO Property, if the New Lease by its terms will give rise to any income that
      does not constitute Rents from Real Property;

     

    (ii)  authorize
      any amount to be received or accrued under any New Lease other than amounts
      that
      will constitute Rents from Real Property;

     

    (iii)  authorize
      any construction on any REO Property, other than the completion of a building
      or
      other improvement thereon, and then only if more than ten percent of the
      construction of such building or other improvement was completed before default
      on the related Mortgage Loan became imminent, all within the meaning of Section
      856(e)(4)(B) of the Code; or

     

    (iv)  authorize
      any Person to Directly Operate any REO Property on any date more than 90 days
      after its date of acquisition by the Trust Fund;

     

    unless,
      in any such case, the Master Servicer has obtained an Opinion of Counsel,
      provided to the Trust Administrator and the Trustee, to the effect that such
      action will not cause such REO Property to fail to qualify as “foreclosure
      property” within the meaning of Section 860G(a)(8) of the Code at any time that
      it is held by the Trust Fund, in which case the Master Servicer may take such
      actions as are specified in such Opinion of Counsel.

     

    The
      Master Servicer may contract with any Independent Contractor for the operation
      and management of any REO Property, provided that:

     

    (i)  the
      terms
      and conditions of any such contract shall not be inconsistent
      herewith;

     

    (ii)  any
      such
      contract shall require, or shall be administered to require, that the
      Independent Contractor pay all costs and expenses incurred in connection with
      the operation and management of such REO Property, including those listed above
      and remit all related revenues (net of such costs and expenses) to the Master
      Servicer as soon as practicable, but in no event later than thirty days
      following the receipt thereof by such Independent Contractor;

     

    (iii)  none
      of
      the provisions of this Section 3.23(c) relating to any such contract or to
      actions taken through any such Independent Contractor shall be deemed to relieve
      the Master Servicer of any of its duties and obligations to the Trustee
      on  behalf of the Certificateholders with respect to the operation and
      management of any such REO Property; and

     

    (iv)  the
      Master Servicer shall be obligated with respect thereto to the same extent
      as if
      it alone were performing all duties and obligations in connection with the
      operation and management of such REO Property.

     

    The
      Master Servicer shall be entitled to enter into any agreement with any
      Independent Contractor performing services for it related to its duties and
      obligations hereunder for indemnification of the Master Servicer by such
      Independent Contractor, and nothing in this Agreement shall be deemed to limit
      or modify such indemnification. The Master Servicer shall be solely liable
      for
      all fees owed by it to any such Independent Contractor, irrespective of whether
      the Master Servicer’s compensation pursuant to Section 3.18 is sufficient to pay
      such fees.

     

    (d)  In
      addition to the withdrawals permitted under Section 3.23(c), the Master Servicer
      may from time to time make withdrawals from the REO Account for any REO
      Property: (i) to pay itself or any Sub-Servicer unpaid Servicing Fees in respect
      of the related Mortgage Loan; and (ii) to reimburse itself or any Sub-Servicer
      for unreimbursed Servicing Advances and P&I Advances made in respect of such
      REO Property or the related Mortgage Loan. Any income from the related REO
      Property received during any calendar months prior to a Final Recovery
      Determination, net of any withdrawals made pursuant to Section 3.23(c) or this
      Section 3.23(d), shall be withdrawn by the Master Servicer from each REO Account
      maintained by it and remitted to the Paying Agent for deposit into the
      Distribution Account in accordance with Section 3.10(d)(ii) on the Master
      Servicer Remittance Date relating to a Final Recovery Determination with respect
      to such Mortgage Loan, for distribution on the related Distribution Date in
      accordance with Section 4.01.

     

    (e)  Subject
      to the time constraints set forth in Section 3.23(a), and further subject to
      obtaining the approval of the insurer under any related Primary Mortgage
      Insurance Policy (if and to the extent that such approvals are necessary to
      make
      claims under such policies in respect of the affected REO Property), each REO
      Disposition shall be carried out by the Master Servicer at such price and upon
      such terms and conditions as the Master Servicer shall deem necessary or
      advisable, as shall be normal and usual in its general servicing activities
      for
      similar properties.

     

    (f)  The
      proceeds from the REO Disposition, net of any amount required by law to be
      remitted to the Mortgagor under the related Mortgage Loan and net of any payment
      or reimbursement to the Master Servicer or any Sub-Servicer as provided above,
      shall be remitted to the Paying Agent for deposit in the Distribution Account
      in
      accordance with Section 3.10(d)(ii) on the Master Servicer Remittance Date
      in
      the month following the receipt thereof for distribution on the related
      Distribution Date in accordance with Section 4.01. Any REO Disposition shall
      be
      for cash only (unless changes in the REMIC Provisions made subsequent to the
      Startup Day allow a sale for other consideration).

     

    (g)  The
      Master Servicer shall file information returns with respect to the receipt
      of
      mortgage interest received in a trade or business, reports of foreclosures
      and
      abandonments of any Mortgaged Property and cancellation of indebtedness income
      with respect to any Mortgaged Property as required by Sections 6050H, 6050J
      and
      6050P of the Code, respectively. Such reports shall be in form and substance
      sufficient to meet the reporting requirements imposed by such Sections 6050H,
      6050J and 6050P of the Code.

    With
      respect to each Collateral Pool, the Master Servicer shall deliver to the Paying
      Agent for deposit into the Distribution Account on or before 12:00 p.m. New
      York
      time on the Master Servicer Remittance Date from its own funds (or from a
      Sub-Servicer’s own funds received by the Master Servicer in respect of
      Compensating Interest) an amount equal to the lesser of (i) the aggregate of
      the
      Prepayment Interest Shortfalls for the related Distribution Date resulting
      from
      full or partial Principal Prepayments of each Mortgage Loan included in such
      Collateral Pool during the related Prepayment Period and (ii) the applicable
      Compensating Interest Payment for such Mortgage Loans.

                Payments.

            


    

     

    In
      the
      event that a shortfall in any collection on or liability with respect to any
      Mortgage Loan results from or is attributable to adjustments to Stated Principal
      Balances that were made by the Master Servicer in a manner not consistent with
      the terms of the related Mortgage Note and this Agreement, the Master Servicer,
      upon discovery or receipt of notice thereof, immediately shall deliver to the
      Paying Agent for deposit in the Distribution Account from its own funds the
      amount of any such shortfall and shall indemnify and hold harmless the Trust
      Fund, the Trustee, the Trust Administrator, the Depositor and any successor
      master servicer in respect of any such liability. Such indemnities shall survive
      the termination or discharge of this Agreement. If amounts paid by the Master
      Servicer with respect to any Mortgage Loan pursuant to this Section 3.25 are
      subsequently recovered from the related Mortgagor, the Master Servicer shall
      be
      permitted to reimburse itself for such amounts paid by it pursuant to this
      Section 3.25 from such recoveries.

    (3)  Reserved.

     

    (4)  Immediately
      prior to the distributions to the Holders of the Certificates on each
      Distribution Date, any adjustments to the Certificate Principal Balances of
      the
      Certificates as required by this paragraph shall be made. For each Collateral
      Pool, an amount equal to the lesser of (x) the amount of related Subsequent
      Recoveries included in the related Available Distribution Amounts for such
      Distribution Date and (y) the aggregate amount of related Realized Losses,
      other
      than Excess Bankruptcy Losses, Excess Fraud Losses, Excess Special Hazard Losses
      and Extraordinary Losses, previously allocated to the related Classes of
      Certificates and that remain outstanding shall be applied as follows: first,
      to
      increase the Certificate Principal Balances of the related Class of Certificates
      with the highest payment priority to which such Realized Losses were previously
      allocated, to the extent of any such Realized Losses previously allocated to
      such Class of Certificates and remaining “unreimbursed”; second, to increase the
      Certificate Principal Balances of the related Class of Certificates with the
      next highest payment priority to which such Realized Losses were previously
      allocated, to the extent of any such Realized Losses previously allocated to
      such Class of Certificates and remaining “unreimbursed”; and so forth. For
      purposes of the foregoing, with respect to any Class of Certificates the amount
      of previously allocated Realized Losses that have been offset by an increase
      in
      Certificate Principal Balances as provided above shall be deemed no longer
      “unreimbursed”. Holders of any Class of Certificates with respect to which there
      shall have been a Certificate Principal Balances increase pursuant to this
      paragraph will not be entitled to any distribution in respect of interest on
      the
      amount of such increase for any Interest Accrual Period preceding the
      Distribution Date on which such increase occurs. Any such increases shall be
      applied to the Certificate Principal Balances of each Class of Certificates
      in
      accordance with its respective Percentage Interest.

     

    All
      references above to the Certificate Principal Balances of any Class of
      Certificates shall be to the Certificate Principal Balances of such Class of
      Certificates prior to the allocation of Extraordinary Trust Fund Expenses and
      Realized Losses, in each case allocated to such Class of Certificates on such
      Distribution Date pursuant to Section 4.04.

     

    (b)  (i)  On
      each Distribution Date, the aggregate distributions of principal made on such
      date in respect of the Group 1 Subordinate Certificates pursuant to Section
      4.01(a)(1)(II)(ii) above and the aggregate distributions of principal made
      on
      such date in respect of the Group 2 Subordinate Certificates pursuant to Section
      4.01(a)(2)(IV)(ii) above, respectively, shall be applied among the various
      Classes thereof, in the order of priority within each Collateral Pool from
      the
      Class of related Subordinate Certificates with the lowest numerical designation
      to the Class of related Subordinate Certificates with the highest numerical
      designation, in each case to the extent of remaining available funds up to
      the
      amount allocable to such Class for such Distribution Date and in each case
      until
      the aggregate Certificate Principal Balance of each such Class is reduced to
      zero, in an amount with respect to each such Class equal to the sum of the
      following with respect to each Loan Group in such Collateral Pool: (X) the
      related Class B Percentage of the amounts described in clauses (i) through
      (v)
      of clause (ii) (a) of the definition of Subordinate Principal Distribution
      Amount, (Y) the portion of the amounts described in clauses (ii) (b), (c) and
      (e) of the definition of Subordinate Principal Distribution Amount allocable
      to
      such Class pursuant to Section 4.01(b)(ii) below and (Z) the excess, if any,
      of
      the amount required to be distributed to such Class pursuant to this Section
      4.01(b)(i) for the immediately preceding Distribution Date, over the aggregate
      distributions of principal made in respect of such Class of Certificates on
      such
      immediately preceding Distribution Date pursuant to Section 4.01 to the extent
      that any such excess is not attributable to Realized Losses which were allocated
      to related Subordinate Certificates with a lower priority pursuant to Section
      4.04.

     

    (ii)  On
      any
      Distribution Date, the amounts with respect to each Group 1 Loan Group described
      in clauses (ii) (b), (c), and (e) of the definition of Subordinate Principal
      Distribution Amount, will be allocated on a pro rata basis among the
      following Classes of Group 1 Subordinate Certificates (each, an “Eligible
      Class”) in proportion to the respective outstanding Certificate Principal
      Balances thereof: (i) the Class 1-B1 Certificates, (ii) the Class 1-B2
      Certificates, if on such Distribution Date the aggregate percentage interest
      in
      Collateral Pool 1 evidenced by the Class 1-B2 Certificates, the Class 1-B3
      Certificates, the Class 1-B4 Certificates, the Class 1-B5 Certificates and
      the
      Class 1-B6 Certificates equals or exceeds 1.60% before giving effect to
      distributions on such Distribution Date, (iii) the Class 1-B3 Certificates,
      if
      on such Distribution Date the aggregate percentage interest in Collateral Pool
      1
      evidenced by the Class 1-B3 Certificates, the Class 1-B4 Certificates, the
      Class
      1-B5 Certificates and the Class 1-B6 Certificates equals or exceeds 1.00% before
      giving effect to distributions on such Distribution Date, (iv) the Class 1-B4
      Certificates, if on such  Distribution Date the aggregate percentage
      interest in Collateral Pool 1 evidenced by the Class 1-B4 Certificates, the
      Class 1-B5 Certificates and the Class 1-B6 Certificates equals or exceeds 0.60%
      before giving effect to distributions on such Distribution Date, (v) the Class
      1-B5 Certificates, if on such Distribution Date the aggregate percentage
      interest in Collateral Pool 1 evidenced by the Class 1-B5 Certificates and
      the
      Class 1-B6 Certificates equals or exceeds 0.40% before giving effect to
      distributions on such Distribution Date and (vi) the Class 1-B6 Certificates,
      if
      on such Distribution Date the percentage interest in Collateral Pool 1 evidenced
      by the Class 1-B6 Certificates equals or exceeds 0.20% before giving effect
      to
      distributions on such Distribution Date. If any of the foregoing Certificates
      is
      not an Eligible Class, any amounts allocable to principal and distributable
      pursuant to this Section 4.01(b)(ii) shall be distributed only among the
      Certificates that are Eligible Classes in the manner set forth
      above.

     

    On
      any
      Distribution Date, the amounts with respect to each Group 2 Loan Group described
      in clauses (ii) (b), (c), and (e) of the definition of Subordinate Principal
      Distribution Amount will be allocated on a pro rata basis among the
      following Classes of Group 2 Subordinate Certificates (each, an “Eligible
      Class”) in proportion to the respective outstanding Certificate Principal
      Balances thereof: (i) the Class 2-B1 Certificates, (ii) the Class 2-B2
      Certificates, if on such Distribution Date the aggregate percentage interest
      in
      Collateral Pool 2 evidenced by the Class 2-B2 Certificates, the Class 2-B3
      Certificates, the Class 2-B4 Certificates, the Class 2-B5 Certificates and
      the
      Class 2-B6 Certificates equals or exceeds 1.60% before giving effect to
      distributions on such Distribution Date, (iii) the Class 2-B3 Certificates,
      if
      on such Distribution Date the aggregate percentage interest in Collateral Pool
      2
      evidenced by the Class 2-B3 Certificates, the Class 2-B4 Certificates, the
      Class
      2-B5 Certificates and the Class 2-B6 Certificates equals or exceeds 1.00% before

      pursuant to this Section 4.01(b)(ii) shall be distributed only among the
      Certificates that are Eligible Classes in the manner set forth
      above.

     

    Notwithstanding
      the foregoing, if the application of the foregoing on any Distribution Date
      as
      provided in Section 4.01 would result in a distribution in respect of principal
      to any Class or Classes of Subordinate Certificates in an amount greater than
      the remaining  Certificate Principal Balance thereof (any such Class,
      a “Maturing Class”) then: (a) the amount to be allocated to each Maturing Class
      shall be reduced to a level that, when applied as described above, would exactly
      reduce the Certificate Principal Balance of such Class to zero and (b) the
      total
      amount of the reduction in the amount to be allocated to the Maturing Class
      or
      Classes shall be allocated among the remaining related Eligible Classes on
      a
pro rata basis in proportion to the respective outstanding Certificate
      Principal Balances thereof prior to the allocation thereto of any of the amounts
      described in the preceding sentence.

     

    (c)  All
      distributions made with respect to each Class of Certificates on each
      Distribution Date shall be allocated pro rata among the outstanding
      Certificates in such Class based on their respective Percentage Interests.
      Payments in respect of each Class of Certificates on each Distribution Date
      will
      be made to the Holders of the respective Class of record on the related Record
      Date (except as otherwise provided in Section 4.01(e) or Section 9.01 respecting
      the final distribution on such Class), based on the aggregate Percentage
      Interest represented by their respective Certificates, and shall be made by
      wire
      transfer of immediately available funds to the account of any such Holder at
      a
      bank or other entity having appropriate facilities therefor, if such Holder
      shall have so notified the Paying Agent in writing at least five Business Days
      prior to the Record Date immediately prior to such Distribution Date and with
      respect to any Class of Certificates other than the Residual Certificates is
      the
      registered owner of Certificates having an initial aggregate Certificate
      Principal Balance that is in excess of the lesser of (i) $5,000,000 or (ii)
      two-thirds of the initial Certificate Principal Balance of such Class of
      Certificates, or otherwise by check mailed by first class mail to the address
      of
      such Holder appearing in the Certificate Register. The final distribution on
      each Certificate will be made in like manner, but only upon presentment and
      surrender of such Certificate at the Corporate Trust Office of the Certificate
      Registrar or such other location specified in the notice to Certificateholders
      of such final distribution.

     

    Each
      distribution with respect to a Book-Entry Certificate shall be paid to the
      Depository, as Holder thereof, and the Depository shall be responsible for
      crediting the amount of such distribution to the accounts of its Depository
      Participants in accordance with its normal procedures. Each Depository
      Participant shall be responsible for disbursing such distribution to the
      Certificate Owners that it represents and to each indirect participating
      brokerage firm (a “brokerage firm” or “indirect participating firm”) for which
      it acts as agent. Each brokerage firm shall be responsible for disbursing funds
      to the Certificate Owners that it represents. None of the Trustee, the Trust
      Administrator, the Paying Agent, the Certificate Registrar, the Authenticating
      Agent, the Depositor or the Master Servicer shall have any responsibility
      therefor except as otherwise provided by this Agreement or applicable
      law.

     

    (d)  The
      rights of the Certificateholders to receive distributions in respect of the
      Certificates, and all interests of the Certificateholders in such distributions,
      shall be as set forth in this Agreement. None of the Holders of any Class of
      Certificates, the Depositor, the Trustee, the Trust Administrator, the
      Authenticating Agent, the Paying Agent, the Certificate Registrar or the Master
      Servicer shall in any way be responsible or liable to the Holders of any other
      Class of Certificates in respect of amounts properly previously distributed
      on
      the Certificates.

     

    (e)  Except
      as
      otherwise provided in Section 9.01, whenever the Trust Administrator expects
      that the final distribution with respect to any Class of Certificates will
      be
      made on the next Distribution Date, the Trust Administrator shall so timely
      advise the Paying Agent and the Paying Agent shall, no later than five days
      after the latest related Determination Date, mail on such date to each Holder
      of
      such Class of Certificates a notice to the effect that:

     

    (i)  the
      Paying Agent expects that the final distribution with respect to such Class
      of
      Certificates will be made on such Distribution Date, but only upon presentation
      and surrender of such Certificates at the office of the Certificate Registrar
      therein specified,

     

    (ii)  no
      interest shall accrue on such Certificates from and after the end of the related
      Interest Accrual Period, and

     

    (iii)  any
      funds
      not distributed to any Holder or Holders of Certificates of such Class on such
      Distribution Date because of the failure of such Holder or Holders to tender
      their Certificates shall, on such date, be set aside and held in trust by the
      Paying Agent and credited to the account of the appropriate non-tendering Holder
      or Holders. If any Certificates as to which notice has been given pursuant
      to
      this Section 4.01(e) shall not have been surrendered for cancellation within
      six
      months after the time specified in such notice, the Paying Agent shall mail
      a
      second notice to the remaining non-tendering Certificateholders to surrender
      their Certificates for cancellation in order to receive the final distribution
      with respect thereto. If within one year after the second notice all such
      Certificates shall not have been surrendered for cancellation, the Paying Agent
      shall, directly or through an agent, mail a final notice to remaining
      non-tendering Certificateholders concerning surrender of their Certificates
      and
      shall continue to hold any remaining funds for the benefit of non-tendering
      Certificateholders. The costs and expenses of maintaining the funds in trust
      and
      of contacting such Certificateholders shall be paid out of the assets remaining
      in such trust fund. If within one year after the final notice any such
      Certificates shall not have been surrendered for cancellation, the Paying Agent
      shall pay to the Citigroup Global Markets Inc. all such amounts, and all rights
      of non-tendering Certificateholders in or to such amounts shall thereupon cease.
      No interest shall accrue or be payable to any Certificateholder on any amount
      held in trust by the Paying Agent as a result of such Certificateholder’s
      failure to surrender its Certificate(s) for final payment thereof in accordance
      with this Section 4.01(e).

      Certificate a statement containing the information set forth in subclauses
      (i)

      with respect to the Residual Certificates, as appropriate, aggregated for such
      calendar year or applicable portion thereof during which such Person was a
      Certificateholder. Such obligation of the Paying Agent shall be deemed to have
      been satisfied to the extent that substantially comparable information shall
      be
      prepared by the Trust Administrator and furnished by the Paying Agent to such
      Holders pursuant to the rules and regulations of the Code as are in force from
      time to time.

     

    Upon
      request, the Paying Agent shall forward to each Certificateholder, during the

      whether or not provided for herein, as shall be reasonable with respect to

                Reports; P&I Advances.

            


    

     

    (a)  On
      the
      second Business Day prior to the related Distribution Date, the Master Servicer
      shall deliver to the Trust Administrator, the Paying Agent and the Trustee
      by
      telecopy (or by such other means as the Master Servicer, the Paying Agent and
      the Trust Administrator and the Trustee may agree from time to time) a
      Remittance Report with respect to the related Distribution Date. Such Remittance
      Report will include (i) the amount of P&I Advances to be made by the Master
      Servicer in respect of the related Distribution Date, the aggregate amount
      of
      P&I Advances outstanding after giving effect to such P&I Advances, and
      the aggregate amount of Nonrecoverable P&I Advances in respect of such
      Distribution Date and (ii) such other information with respect to the Mortgage
      Loans as the Trust Administrator or the Paying Agent may reasonably require
      to
      perform the calculations necessary for the Paying Agent to make the
      distributions contemplated by Section 4.01 and for the Trust Administrator
      to
      prepare the statements to Certificateholders contemplated by Section 4.02;
      provided, however, that if the Master Servicer is not the Trust Administrator,
      the Master Servicer will forward to the successor Trust Administrator the
      information set forth in clause (i) above on the next Business Day following
      the
      latest related Determination Date and the information set forth in clause (ii)
      above on the fifth Business Day following the last day of the related calendar
      month. Neither the Trustee, the Paying Agent nor the Trust Administrator shall
      be responsible to recompute, recalculate or verify any information provided
      to
      it by the Master Servicer.

     

    (b)  The
      amount of P&I Advances to be made by the Master Servicer for any
      Distribution Date shall equal, subject to Section 4.03(d), the sum of (i) the
      aggregate amount of Monthly Payments (with each interest portion thereof net
      of
      the related Servicing Fee), due on the related Due Date in respect of the
      Mortgage Loans, which Monthly Payments were delinquent as of the close of
      business on the related Determination Date and (ii) with respect to each REO
      Property, which REO Property was acquired during or prior to the related
      Prepayment Period and as to which such REO Property an REO Disposition did
      not
      occur during the related Prepayment Period, an amount equal to the Monthly
      Payments (with each interest portion thereof net of the related Servicing Fee)
      that would have been due on the related Due Date in respect of the related
      Mortgage Loans.

     

    On
      or
      before 12:00 p.m. New York time on the Master Servicer Remittance Date, the
      Master Servicer shall remit in immediately available funds to the Paying Agent
      for deposit in the Distribution Account an amount equal to the aggregate amount
      of P&I Advances, if any, to be made in respect of the Mortgage Loans and REO
      Properties for the related Distribution Date either (i) from its own funds
      or,
      if received from a Sub-Servicer, from funds remitted by a Sub-Servicer in
      payment of required P&I Advances or (ii) from the Collection Account, to the
      extent of funds held therein for future distribution (in which case, it will
      cause to be made an appropriate entry in the records of Collection Account
      that
      amounts held for future distribution have been, as permitted by this Section
      4.03, used by the Master Servicer in discharge of any such P&I Advance) or
      (iii) in the form of any combination of (i) and (ii) aggregating the total
      amount of P&I Advances to be made by the Master Servicer with respect to the
      Mortgage Loans and REO Properties. Any amounts held for future distribution
      and
      so used shall be appropriately reflected in the Master Servicer’s records and
      replaced by the Master Servicer by deposit in the Collection Account on or
      before any future Master Servicer Remittance Date to the extent that the
      Available Distribution Amount for the related Distribution Date (determined
      without regard to P&I Advances to be made on the Master Servicer Remittance
      Date) shall be less than the total amount that would be distributed to the
      Classes of Certificateholders pursuant to Section 4.01 on such Distribution
      Date
      if such amounts held for future distributions had not been so used to make
      P&I Advances. The Trust Administrator will provide notice to the Master
      Servicer by telecopy by the close of business on the Master Servicer Remittance
      Date in the event that the amount remitted by the Master Servicer to the Trust
      Administrator on such Master Servicer Remittance Date is less than the P&I
      Advances required to be made by the Master Servicer for the related Distribution
      Date.

     

    (c)  The
      obligation of the Master Servicer to make such P&I Advances is mandatory,
      notwithstanding any other provision of this Agreement but subject to (d) below,
      and, with respect to any Mortgage Loan or REO Property, shall continue until
      a
      Final Recovery Determination in connection therewith or the removal thereof
      from
      REMIC I-A or REMIC II-A pursuant to any applicable provision of this Agreement,
      except as otherwise provided in this Section.

     

    (d)  Notwithstanding
      anything herein to the contrary, no P&I Advance shall be required to be made
      hereunder by the Master Servicer if such P&I Advance would, if made,
      constitute a Nonrecoverable P&I Advance. The determination by the Master
      Servicer that it has made a Nonrecoverable P&I Advance or that any proposed
      P&I Advance, if made, would constitute a Nonrecoverable P&I Advance,
      shall be evidenced by an Officers’ Certificate of the Master Servicer delivered
      to the Depositor, the Trust Administrator, the Paying Agent and the
      Trustee.

     

    (e)  If
      the
      Master Servicer shall fail to make any P&I Advance on any Master Servicer
      Remittance Date required to be made from its own funds pursuant to this Section
      4.03, then the Paying Agent, by not later than 1:00 p.m. on the related
      Distribution Date, shall make such P&I advance from its own funds by
      depositing the amount of such advance into the Distribution Account, and the
      Trust Administrator and the Paying Agent shall include the amount so advanced
      by
      the Paying Agent in the Available Distribution Amount distributed on such
      Distribution Date.

                Losses.

            


    

     

    (a)  Prior
      to
      each Distribution Date, the Master Servicer shall determine as to each Mortgage
      Loan and REO Property: (i) the total amount of Realized Losses, if any, incurred
      in connection with any Final Recovery Determinations made during the related
      Prepayment Period; (ii) whether and the extent to which such Realized Losses
      constituted Fraud Losses or Special Hazard Losses; and (iii) the respective
      portions of such Realized Losses allocable to interest and allocable to
      principal. Prior to each Distribution Date, the Master Servicer shall also
      determine as to each Mortgage Loan: (A) the total amount of Realized Losses,
      if
      any, incurred in connection with any Deficient Valuations made during the
      related Prepayment Period; and (B) the total amount of Realized Losses, if
      any,
      incurred in connection with Debt Service Reductions in respect of Monthly
      Payments due during the related Due Period. The information described in the
      two
      preceding sentences that is to be supplied by the Master Servicer shall be
      evidenced by an Officers’ Certificate delivered to the Trust Administrator, the
      Paying Agent and the Trustee by the Master Servicer prior to the Determination
      Date immediately following the end of (x) in the case of Bankruptcy Losses
      allocable to interest, the Due Period during which any such Realized Loss was
      incurred, and (y) in the case of all other Realized Losses, the Prepayment
      Period during which any such Realized Loss was incurred.

     

    (b)  Following
      all distributions to be made pursuant to Section 4.01 on a Distribution Date,
      all Realized Losses determined by the Master Servicer as described in (a) above
      on the Mortgage Loans related to each Collateral Pool (other than Excess Losses)
      shall be allocated on each Distribution Date in reverse sequential order to
      the
      related Subordinate Certificates, in each case until the Certificate Principal
      Balance thereof has been reduced to zero.

     

    Thereafter,
      (i) with respect to Collateral Pool 1, upon the reduction of the Certificate
      Principal Balances of the related Subordinate Certificates to zero, all such
      Realized Losses on the Mortgage Loans related to such Collateral Pool (other
      than Excess Losses) shall be allocated on any Distribution Date, to the Class
      1-A1A Certificates and the Class 1-A2B Certificates as described below (if
      the
      Realized Loss is on a Group 1 Mortgage Loan), and (ii) with respect to
      Collateral Pool 2, upon the reduction of the Certificate Principal Balances
      of
      the related Subordinate Certificates to zero, all such Realized Losses on the
      Mortgage Loans related to such Collateral Pool (other than Excess Losses) shall
      be allocated on any Distribution Date to the Class 2-A1A Certificates and the
      Class 2-A1B Certificates as described below (if the Realized Loss is on a Group
      2-1 Mortgage Loan), to the Class 2-A2A Certificates and the Class 2-A2B
      Certificates as described below (if the Realized Loss is on a Group 2-2 Mortgage
      Loan) to the Class 2-A3A Certificates and the Class 2-A3B Certificates as
      described below (if the Realized Loss is on a Group 2-3 Mortgage
      Loan).

    


    Excess
      Losses on the Group 1 Mortgage Loans incurred during any Prepayment Period
      will
      be allocated on the related Distribution Date by allocating (i) the Group 1
      Senior Percentage of the Excess Loss to the Class 1-A1A Certificates and Class
      1-A1B Certificates as described below (if the Excess Loss is on a Group 1
      Mortgage Loan) and (ii) the related Group 1 Subordinate Percentage of the Excess
      Loss to the Group 1 Subordinate Certificates on a pro rata
      basis.

     

    Excess
      Losses on the Group 2 Mortgage Loans incurred during any Prepayment Period
      will
      be allocated on the related Distribution Date by allocating (i) the related
      Group 2 Senior Percentage (related to the Loan Group in which the Mortgage
      Loan
      that suffered the Excess Loss is included) of the Excess Loss to the Class
      2-A1A
      Certificates and Class 2-A1B Certificates as described below (if the Excess
      Loss
      is on a Group 2-1 Mortgage Loan), to the Class 2-A2A Certificates and Class
      2-A2B Certificates as described below (if the Excess Loss is on a Group 2-2
      Mortgage Loan), to the Class 2-A3A Certificates and Class 2-A3B Certificates
      as
      described below (if the Excess Loss is on a Group 2-3 Mortgage Loan), to the
      Class 2-A4A Certificates and Class 2-A4B Certificates as described below (if
      the
      Excess Loss is on a Group 2-4 Mortgage Loan) and (ii) the related Group 2
      Subordinate Percentage (related to the Loan Group in which the Mortgage Loan
      that suffered the Excess Loss is included) of the Excess Loss to the Group
      2
      Subordinate Certificates on a pro rata basis.

     

    Any
      Extraordinary Trust Fund Expenses relating to Collateral Pool 1 incurred during
      any Prepayment Period will be allocated on the related Distribution Date as
      follows: first, to the Class 1-B6 Certificates; second, to the Class 1-B5
      Certificates; third, to the Class 1-B4 Certificates; fourth, to the Class 1-B3
      Certificates; fifth, to the Class 1-B2 Certificates; and sixth, to the Class
      1-B1 Certificates, in each case until the Certificate Principal Balance of
      such
      Class has been reduced to zero. Thereafter, any Extraordinary Trust Fund
      Expenses relating to Collateral Pool 1 will be allocated on any Distribution
      Date among the Group 1 Class A Certificates on a pro rata basis. Any
      Extraordinary Trust Fund Expenses relating to Collateral Pool 2 incurred during
      any Prepayment Period will be allocated on the related Distribution Date as
      follows: first, to the Class 2-B6 Certificates; second, to the Class 2-B5
      Certificates; third, to the Class 2-B4 Certificates; fourth, to the Class 2-B3
      Certificates; fifth, to the Class 2-B2 Certificates; and sixth, to the Class
      2-B1 Certificates, in each case until the Certificate Principal Balance of
      such
      Class has been reduced to zero. Thereafter, the Extraordinary Trust Fund
      Expenses relating to Collateral Pool 2 will be allocated on any Distribution
      Date among the Group 2 Class A Certificates on a pro rata
      basis.

     

    Notwithstanding
      the foregoing, with respect to Collateral Pool 1, any Excess Loss that is
      allocated to the Class 1-A1A Certificates and Class 1-A1B Certificates will
      be
      allocated between such Classes on a pro rata basis, and any Realized
      Losses (other than any Excess Losses) allocated to the Class 1-A1A Certificates
      and Class 1-A1B Certificates will be allocated first to the Class 1-A1B
      Certificates until the Certificate Principal Balance thereof has been reduced
      to
      zero and then to the Class 1-A1A Certificates.

     

    Notwithstanding
      the foregoing, with respect to Collateral Pool 2, (i) any Excess Loss that
      is
      allocated to the Class 2-A1A Certificates and Class 2-A1B Certificates will
      be
      allocated between such Classes on a pro rata basis; and any Realized
      Losses (other than any Excess Losses) allocated to the Class 2-A1A Certificates
      and Class 2-A1B Certificates will be allocated first to the Class 2-A1B
      Certificates until the Certificate Principal Balance thereof  has been
      reduced to zero and then to the Class 2-A1A Certificates, (ii) any Excess Loss
      that is allocated to the Class 2-A2A Certificates and Class 2-A2B Certificates
      will be allocated between such Classes on a pro rata basis, and any
      Realized Losses (other than any Excess Losses) allocated to the Class 2-A2A
      Certificates and Class 2-A2B Certificates will be allocated first to the Class
      2-A2B Certificates until the Certificate Principal Balance thereof has been
      reduced to zero and then to the Class 2-A2A Certificates and (iii) any Excess
      Loss that is allocated to the Class 2-A3A Certificates and Class 2-A3B
      Certificates will be allocated between such Classes on a pro rata
      basis, and any Realized Losses (other than any Excess Losses) allocated to
      the
      Class 2-A3A Certificates and Class 2-A3B Certificates will be allocated first
      to
      the Class 2-A3B Certificates until the Certificate Principal Balance thereof
      has
      been reduced to zero and then to the Class 2-A3A Certificates.

     

    Notwithstanding
      the method of allocation of Realized Losses and Extraordinary Fund Expenses
      above, if any overcollateralization exists when Realized Losses or Extraordinary
      Trust Fund Expenses are to be allocated, such Realized Losses or Extraordinary
      Trust Fund Expenses will be allocated first to the overcollateralization, until
      the overcollateralization is reduced to zero, prior to allocating such Realized
      Losses or Extraordinary Trust Fund Expenses to the Certificates in accordance
      with the priorities set forth above.

     

    As
      used
      herein, an allocation of a Realized Loss or Extraordinary Trust Fund Expense
      on
      a “pro rata basis” among two or more specified Classes of Certificates
      means an allocation on a pro rata basis, among the various Classes so
      specified, to each such Class of Certificates on the basis of their then
      outstanding Certificate Principal Balances prior to giving effect to
      distributions to be made on such Distribution Date. All Realized Losses and
      all
      other losses allocated to a Class of Certificates hereunder will be allocated
      among the Certificates of such Class in proportion to the Percentage Interests
      evidenced thereby. Any allocation of a Realized Loss of Extraordinary Trust
      Fund
      Expense to a Certificate shall be made by reducing the Certificate Principal
      Balance thereof by the amount so allocated as of the Distribution Date following
      the Prepayment Period in which such Realized Loss was incurred.

     

    (c)  Notwithstanding
      anything to the contrary herein, in no event shall the Certificate Principal
      Balance of a Class A Certificate be reduced more than once in respect of any
      particular amount both (i) allocable to such Certificate in respect of Realized
      Losses or Extraordinary Trust Fund Expenses pursuant to Section 4.04 and (ii)
      payable to the Holder of such Certificate pursuant to Section 4.01(a) as a
      portion of the Senior Principal Distribution Amount.

      Data Gathering and Retrieval System (“EDGAR”), a distribution report on Form
      10-D, signed by the Master Servicer, with a copy of the monthly statement to
      be
      furnished by the Trust Administrator to the Certificateholders for such
      Distribution Date.  Any disclosure in addition to the monthly
      statement required to be included on the Form 10-D (“Additional Form 10-D
      Disclosure”) shall be determined and prepared by the entity that is indicated in
      Exhibit B as the responsible party for providing that information, and shall
      be
      reported by such entity to the Depositor and the Trust Administrator and
      approved by the Depositor.  The Trust Administrator shall have no duty
      or liability for any failure hereunder to determine or prepare any Additional
      Form 10-D Disclosure absent such reporting (other than in the case where the
      Trust Administrator is the reporting party as set forth in Exhibit B) and
      approval, and the Trust Administrator will have no duty or liability to verify
      the accuracy or sufficiency of any such Additional Form 10-D Disclosure (except
      in any case where the Trust Administrator is the responsible party for providing
      that information pursuant to Exhibit B).

     

    Within
      5
      calendar days after the related Distribution Date (or if not a Business Day,
      the
      immediately preceding Business Day), each entity that is indicated in Exhibit
      B
      as the responsible party for providing Additional Form 10-D Disclosure shall
      be
      required to provide to the Trust Administrator and the Depositor, to the extent
      known, in EDGAR-compatible format, or in such other form as otherwise agreed
      upon by the Trust Administrator and the Depositor and such party, and clearly
      identifying which item of Form 10-D the information relates to, any Additional
      Form 10-D Disclosure, if applicable.  The Trust Administrator shall
      compile the information provided to it, prepare the Form 10-D and forward the
      Form 10-D to the Depositor.  The Depositor will approve, as to form
      and substance, or disapprove, as the case may be, the Additional Form 10-D
      Disclosure.

     

    After
      preparing the Form 10-D, the Trust Administrator shall forward electronically
      a
      copy of the Form 10-D to the Depositor (in every case where the Form 10-D
      includes Additional 10-D Disclosure and otherwise if requested by the Depositor)
      and the Master Servicer for review.  Within two Business Days after
      receipt of such copy, but no later than the 12th calendar day after the
      Distribution Date (provided that, the Trust Administrator shall have forwarded
      a
      copy of the Form 10-D no later than the 10th calendar after the Distribution
      Date), the Depositor shall notify the Trust Administrator in writing (which
      may
      be furnished electronically) of any changes to or approval of such Form
      10-D.  In the absence of receipt of any written changes or approval,
      the Trust Administrator shall be entitled to assume that such Form 10-D is
      in
      final form and the Trust Administrator may proceed with arrangements for the
      execution of, and filing of, the Form 10-D.  No later than 2 Business
      Days prior to the 15th calendar day after the related Distribution Date, a
      duly
      authorized officer of the Master Servicer shall sign the Form 10-D and return
      an
      electronic or fax copy of such signed Form 10-D (with an original executed
      hard
      copy to follow by overnight mail) to the Trust Administrator.  If a
      Form 10-D cannot be filed on time or if a previously filed Form 10-D needs
      to be
      amended, the Trust Administrator shall follow the procedures set forth in
      Section 4.06(a)(v). Once the Form 10-D has been filed with the Commission it
      will be available through EDGAR at www.sec.gov.  The Trust
      Administrator will provide copies of the report to investors, free of charge,
      upon request.  The parties to this Agreement acknowledge that the
      performance by the Master Servicer and the Trust Administrator of their
      respective duties under Sections 4.06(a)(i) and (v) related to the timely
      preparation, execution and filing of Form 10-D is contingent upon such parties
      strictly observing all applicable deadlines in the performance of their duties
      under such Sections.  Neither the Master Servicer nor the Trust
      Administrator shall have any liability for any loss, expense, damage, claim
      arising out of or with respect to any failure to properly prepare, execute
      and/or timely file such Form 10-D, where such failure results from the Master
      Servicer’s or the Trust Administrator’s inability or failure to receive, on a
      timely basis, any information from any other party hereto needed to prepare,
      arrange for execution or file such Form 10-D, not resulting from its own
      negligence, bad faith or willful misconduct.

     

    (ii)  Within
      4
      Business Days after the occurrence of an event requiring disclosure on Form
      8-K
      (each such event, a “Reportable Event”), the Trust Administrator shall prepare
      and file, at the direction of the Depositor, on behalf of the Trust, any Form
      8-K, as required by the Exchange Act; provided that, the Depositor shall file
      the initial Form 8-K in connection with the issuance of the
      Certificates.  Any disclosure or information related to a Reportable
      Event or that is otherwise required to be included on Form 8-K (“Form 8-K
      Disclosure Information”) shall be, pursuant to the paragraph immediately below,
      reported by the responsible parties set forth on Exhibit B to the Trust
      Administrator and the Depositor and approved by the Depositor, and the Trust
      Administrator will have no duty or liability for any failure hereunder to
      determine or prepare any Form 8-K absent such reporting (other than in the
      case
      where the Trust Administrator is the reporting party as set forth in Exhibit
      B)
      and approval.

     

    For
      so
      long as the Trust is subject to the Exchange Act reporting requirements, no
      later than 5:00 p.m. New York City time on the 2nd Business Day after the
      occurrence of a Reportable Event (i) the responsible parties set forth in
      Exhibit B shall be required pursuant to Section 4.06(a)(iv) below to provide
      to
      the Trust Administrator and the Depositor, to the extent known by a responsible
      officer thereof, in EDGAR-compatible format, or in such other form as otherwise
      agreed upon by the Trust Administrator and the Depositor and such party, the
      form and substance of any Form 8-K Disclosure Information, if applicable, and
      (ii) the Depositor shall approve, as to form and substance, or disapprove,
      as
      the case may be, the inclusion of the Form 8-K Disclosure Information on Form
      8-K.

     

    After
      preparing the Form 8-K, the Trust Administrator shall forward electronically
      a
      copy of the Form 8-K to the Depositor and the Master Servicer for
      review.  No later than the close of business New York City time on the
      3rd Business Day after the Reportable Event, an officer of the Master Servicer
      shall sign the Form 8-K and, return an electronic or fax copy of such signed
      Form 8-K (with an original executed hard copy to follow by overnight mail)
      to
      the Trust Administrator.  Promptly, but no later than the close of
      business on the 3rd Business Day after the Reportable Event (provided that,
      the
      Trust Administrator shall have forwarded a copy of the Form 8-K no later than
      the 2nd Business Day after the Reportable Event), the Depositor shall notify
      the
      Trust Administrator in writing (which may be furnished electronically) of any
      changes to or approval of such Form 8-K.  In the absence of receipt of
      any written changes or approval, the Trust Administrator shall be entitled
      to
      assume that such Form 8-K is in final form and the Trust Administrator may
      proceed with arrangements for the execution of, and filing of, the Form
      8-K.   If a Form 8-K cannot be filed on time or if a previously
      filed Form 8-K needs to be amended, the Trust Administrator shall follow the
      procedures set forth in Section 4.06(a)(v).  Once the Form 8-K has
      been filed with the Commission it will be available through EDGAR at
      www.sec.gov.  The Trust Administrator will provide copies of the
      report to investors, free of charge, upon request.  The parties to
      this Agreement acknowledge that the performance by Master Servicer and the
      Trust
      Administrator of their respective duties under this Section 4.06(a)(ii) related
      to the timely preparation, execution and filing of Form 8-K is contingent upon
      such parties strictly observing all applicable deadlines in the performance
      of
      their duties under this Section 4.06(a)(ii).  Neither the Master
      Servicer nor the Trust Administrator shall have any liability for any loss,
      expense, damage, claim arising out of or with respect to any failure to properly
      prepare, execute and/or timely file such Form 8-K, where such failure results
      from the Master Servicer’s or the Trust Administrator’s inability or failure to
      receive, on a timely basis, any information from any other party hereto needed
      to prepare, arrange for execution or file such Form 8-K, not resulting from
      its
      own negligence, bad faith or willful misconduct.

     

    (iii)  Within
      90
      days after the end of each fiscal year of the Trust or such earlier date as
      may
      be required by the Exchange Act (the “10-K Filing Deadline”) (it being
      understood that the fiscal year for the Trust ends on December 31st of each
      year), commencing in March 2008, the Trust Administrator shall prepare and
      file
      on behalf of the Trust a Form 10-K, in form and substance as required by the
      Exchange Act.  Each such Form 10-K shall include the following items,
      in each case to the extent they have been delivered to the Trust Administrator
      within the applicable time frames set forth in this Agreement, (I) an Annual
      Statement of Compliance for the Master Servicer and any Sub-servicer, as
      provided under Section 3.20, (II)(A) the Assessments of Compliance for the

      Trust Administrator’s, the Paying Agent’s or either Custodian’s Assessments of
      Compliance identifies any material instance of noncompliance, disclosure
      identifying such instance of noncompliance, or if the Master Servicer’s, any
      Sub-servicer’s or subcontractor’s participating in the servicing function, the
      Trust Administrator’s, the Paying Agent’s or either Custodian’s Assessments of
      Compliance is not included as an exhibit to such Form 10-K, disclosure that
      such
      report is not included and an explanation why such report is not included,
      (III)(A) the Attestation Report for the Master Servicer, each Sub-servicer
      and
      subcontractor participating in the servicing function, the Trust Administrator,
      the Paying Agent and either Custodian, as provided under Section 3.21, and
      (B)
      if any Attestation Report rendered as contemplated under Section 3.21 identifies
      any material instance of noncompliance, disclosure identifying such instance
      of
      noncompliance, or if any such Attestation Report is not included as an exhibit
      to such Form 10-K, disclosure that such report is not included and an
      explanation why such report is not included, and (IV) a Master Servicer
      Certification in the form prescribed by Exhibit H (provided, however, that
      the
      Trust Administrator, at its discretion, may omit from the Form 10-K any annual
      compliance statement, assessment of compliance or attestation report that is
      not
      required to be filed with such Form 10-K pursuant to Regulation AB). Any
      disclosure or information in addition to (I) through (IV) above that is required
      to be included on Form 10-K (“Additional Form 10-K Disclosure”) shall be,
      pursuant to the paragraph immediately below, reported by the responsible parties
      set forth on Exhibit B to the Trust Administrator and the Depositor and approved
      by the Depositor, and the Trust Administrator will have no duty or liability
      for
      any failure hereunder to determine or prepare any Additional Form 10-K
      Disclosure absent such reporting (other than in the case where the Trust
      Administrator is the reporting party as set forth in Exhibit B) and
      approval.

     

    No
      later
      than March 15th of each year that the Trust is subject to the Exchange Act
      reporting requirements, commencing in 2008, (A) the responsible parties set
      forth in Exhibit B shall be required to provide pursuant to Section 4.06(a)(iv)
      below to the Trust Administrator and the Depositor, to the extent known by
      a
      responsible officer thereof, in EDGAR-compatible format, or in such other form
      as otherwise agreed upon by the Trust Administrator and the Depositor and such
      party, the form and substance of any Additional Form 10-K Disclosure, if
      applicable, and (ii) the Depositor will approve, as to form and substance,
      or
      disapprove, as the case may be, the inclusion of the Additional Form 10-K
      Disclosure on Form 10-K.

     

    After
      preparing the Form 10-K, the Trust Administrator shall forward electronically
      a
      copy of the Form 10-K to the Depositor and the Master Servicer for
      review.  Within 3 Business Days after receipt of such copy, but no
      later than March 25th (provided that, the Trust Administrator forwards a copy
      of
      the Form 10-K no later than the 3rd Business Day prior to March 25th), the
      Depositor shall notify the Trust Administrator in writing (which may be
      furnished electronically) of any changes to or approval of such Form
      10-K.  In the absence of receipt of any written changes or approval,
      the Trust Administrator shall be entitled to assume that such Form 10-K is
      in
      final form and the Trust Administrator may proceed with the execution and filing
      of the Form 10-K.  No later than 12:00 p.m. Eastern Standard time on
      the 4th Business Day prior to the 10-K Filing Deadline, an officer of the Master
      Servicer in charge of the master servicing function shall sign the Form 10-K
      and
      return an electronic or fax copy of such signed Form 10-K (with an original
      executed hard copy to follow by overnight mail) to the Trust
      Administrator.  If a Form 10-K cannot be filed on time or if a
      previously filed Form 10-K needs to be amended, the Trust Administrator will
      follow the procedures set forth in Section 4.06(a)(v).  Once the Form
      10-K has been filed with the Commission it will be available through EDGAR
      at
      www.sec.gov.  The Trust Administrator will provide copies of the
      report to investors, free of charge, upon request.  The parties to
      this Agreement acknowledge that the performance by the Master Servicer and
      the
      Trust Administrator of their respective duties under Sections
      4.06(a)(iii)  through (v) related to the timely preparation, execution
      and filing of Form 10-K is contingent upon such parties strictly observing
      all
      applicable deadlines in the performance of their duties under such Sections
      and
      under Section 3.20 and Section 3.21.  Neither the Master Servicer nor
      the Trust Administrator shall have any liability for any loss, expense, damage,
      claim arising out of or with respect to any failure to properly prepare, execute
      and/or timely file such Form 10-K, where such failure results from the Master
      Servicer’s or the Trust Administrator’s inability or failure to receive, on a
      timely basis, any information from any other party hereto needed to prepare,
      arrange for execution or file such Form 10-K, not resulting from its own
      negligence, bad faith or willful misconduct.

     

    The
      Master Servicer shall deliver the Master Servicer Certification, executed by
      an
      officer of the Master Servicer in charge of the master servicing function,
      to
      the Trust Administrator not later than March 15th of each year in which the
      Trust is subject to the reporting requirements of the Exchange
      Act.   (b)In connection with the filing of any 10-K hereunder, in
      the case where the Master Servicer and Trust Administrator are not affiliated,
      the Trust Administrator shall sign a Back-Up Certification substantially in
      the
      form of Exhibit I; provided, however, that the Trust Administrator shall not
      be
      required to undertake an analysis of any accountant’s report attached as an
      exhibit to the Form 10-K.

     

    (iv)  With
      respect to any Additional Form 10-D Disclosure, Additional Form 10-K Disclosure
      or any Form 8-K Disclosure Information (collectively, the “Additional
      Disclosure”) relating to the Trust Fund, the Trust Administrator’s obligation to
      include such Additional Disclosure in the applicable Exchange Act report is
      subject to receipt from the entity that is indicated in Exhibit B as the
      responsible party for providing that information, if other than the Trust
      Administrator, as and when required as described in Section 4.06(a)(i) through
      (iii) above.  Each of the Master Servicer, Sponsor, Trust
      Administrator and Depositor hereby agrees to notify and provide to the extent
      known to the Master Servicer, the Sponsor, the Trust Administrator and the
      Depositor all Additional Disclosure relating to the Trust Fund, with respect
      to
      which such party is indicated in Exhibit B as the responsible party for
      providing that information.

     

    So
      long
      as the Depositor is subject to the filing requirements of the Exchange Act
      with
      respect to the Trust Fund, the Trustee shall notify the Trust Administrator
      and
      the Depositor of any bankruptcy or receivership with respect to the Trustee
      or
      of any proceedings of the type described under Item 1117 of Regulation AB that
      have occurred as of the related Due Period, together with a description thereof,
      no later than the date on which such information is required of other parties
      hereto as set forth under this Section 4.06.  In addition, the Trustee
      shall notify the Trust Administrator and the Depositor of any affiliations
      or
      relationships that develop after the Closing Date between the Trustee and the
      Depositor, the Sponsor, the Trust Administrator, the Master Servicer, the
      Servicer or either Custodian of the type described under Item 1119 of Regulation
      AB, together with a description thereof, no later than the date on which such
      information is required of other parties hereto as set forth under this Section
      4.06.

     

    The
      Master Servicer shall be responsible for determining the pool concentration
      applicable to any Sub-Servicer to which any of the Master Servicer’s
      responsibilities with respect to the Mortgage Loans have been delegated at
      any
      time, for purposes of disclosure as required by Items 1117 and 1119 of
      Regulation AB.  The Trust Administrator will provide electronic or
      paper copies of all Form 10-D, 8-K and 10-K filings free of charge to any
      Certificateholder upon written request.  Any expenses incurred by the
      Trust Administrator in connection with the previous sentence shall be
      reimbursable to the Trust Administrator out of the Trust Fund.

     

    (v)  (A)           On
      or prior to January 30th of the first year in which the Trust Administrator
      is
      able to do so under applicable law, the Trust Administrator shall prepare and
      file a Form 15 relating to the automatic suspension of reporting in respect
      of
      the Trust under the Exchange Act.

     

    (B)           In
      the event that the Trust Administrator is unable to timely file with the
      Commission all or any required portion of any Form 8-K, 10-D or 10-K required
      to
      be filed by this Agreement because required disclosure information was either
      not delivered to it or delivered to it after the delivery deadlines set forth
      in
      this Agreement or for any other reason, the Trust Administrator shall promptly
      notify the Depositor and the Master Servicer.  In the case of Form
      10-D and 10-K, the Depositor, the Master Servicer and the Trust Administrator
      shall cooperate to prepare and file a Form 12b-25 and a 10-DA and 10-KA as
      applicable, pursuant to Rule 12b-25 of the Exchange Act.  In the case
      of Form 8-K, the Trust Administrator will, upon receipt of all required Form
      8-K
      Disclosure Information and upon the approval and direction of the Depositor,
      include such disclosure information on the next Form 10-D.  In the
      event that any previously filed Form 8-K, 10-D or 10-K needs to be amended,
      and
      such amendment relates to any Additional Disclosure, the Trust Administrator
      shall notify the Depositor and the parties affected thereby and such parties
      will cooperate to prepare any necessary Form 8-KA, 10-DA or
      10-KA.  Any Form 15, Form 12b-25 or any amendment to Form 8-K, 10-D or
      10-K shall be signed by a duly authorized officer of the Master
      Servicer.  The parties hereto acknowledge that the performance by the
      Master Servicer and the Trust Administrator of their respective duties under
      this Section 4.06(a)(v) related to the timely preparation, execution and filing
      of Form 15, a Form 12b-25 or any amendment to Form 8-K, 10-D or 10-K is
      contingent upon the Master Servicer and the Depositor timely performing their
      duties under this Section.  Neither the Master Servicer nor the Trust
      Administrator shall have any liability for any loss, expense, damage, claim
      arising out of or with respect to any failure to properly prepare, execute
      and/or timely file any such Form 15, Form 12b-25 or any amendments to Form
      8-K,
      10-D or 10-K, where such failure results from the Master Servicer’s or the Trust
      Administrator’s inability or failure to receive, on a timely basis, any
      information from any other party hereto needed to prepare, arrange for execution
      or file such Form 15, Form 12b-25 or any amendments to Form 8-K, 10-D or 10-K,
      not resulting from its own negligence, bad faith or willful
      misconduct.

     

    The
      Depositor agrees to promptly furnish to the Trust Administrator, from time
      to
      time upon request, such further information, reports and financial statements
      within its control related to this Agreement or the Mortgage Loans as the Trust
      Administrator reasonably deems appropriate to prepare and file all necessary
      reports with the Commission. The Trust Administrator shall have no
      responsibility to file any items other than those specified in this Section
      4.06; provided, however, the Trust Administrator shall cooperate with the
      Depositor in connection with any additional filings with respect to the Trust
      Fund as the Depositor deems necessary under the Exchange Act.  Fees
      and expenses incurred by the Trust Administrator in connection with this Section
      4.06 shall not be reimbursable from the Trust Fund.

     

    (b)  Without
      limiting any other indemnification provided pursuant to any other Section of
      this Agreement, the Trust Administrator shall indemnify and hold harmless,
      the
      Depositor and the Master Servicer and each of their respective officers,
      directors and affiliates from and against any losses, damages, penalties, fines,
      forfeitures, reasonable and necessary legal fees and related costs, judgments
      and other costs and expenses arising out of or based upon a breach of the Trust
      Administrator’s obligations under Sections 3.21 or 4.06 or the Trust
      Administrator’s negligence, bad faith or willful misconduct in connection
      therewith. In addition, the Trust Administrator shall indemnify and hold
      harmless the Depositor and each of its officers, directors and affiliates and
      the Master Servicer from and against any losses, damages, penalties, fines,
      forfeitures, reasonable and necessary legal fees and related costs, judgments
      and other costs and expenses that (i) arise out of or are based upon any untrue
      statement or alleged untrue statement of any material fact contained in any
      Back-Up Certification, the Assessment of Compliance, any Additional Disclosure
      or other information provided by the Trust Administrator pursuant to Section
      3.21 or 4.06 (the “Trust Administrator Information”), or (ii) arise out of or
      are based upon the omission or alleged omission to state therein a material
      fact
      required to be stated therein or necessary to make the statements therein,
      in

      the amount paid or payable by the Depositor as a result of the losses, claims,
      damages or liabilities of the Depositor in such proportion as is appropriate
      to
      reflect the relative fault of the Depositor on the one hand and the Paying
      Agent
      on the other. Notwithstanding the foregoing, in no event shall the Paying Agent
      be liable under this paragraph for any consequential, indirect or punitive

              SECTION
                5.01  

            	
              The
                Certificates.

            


    

     

    (a)  The
      Certificates in the aggregate will represent the entire beneficial ownership
      interest in the Mortgage Loans and all other assets included in the Trust Fund.
      At the Closing Date, the aggregate Certificate Principal Balance of the
      Certificates will equal the aggregate Stated Principal Balance of the Mortgage
      Loans.

     

    The
      Certificates will be substantially in the forms annexed hereto as Exhibits
      A-1
      through A-23. The Certificates of each Class will be issuable in registered
      form
      only, in denominations of authorized Percentage Interests as described in the
      definition thereof. Each Certificate will share ratably in all rights of the
      related Class.

     

    Upon
      original issue, the Certificates shall be executed by the Paying Agent and
      delivered by the Authenticating Agent to or upon the order of the Depositor.
      The
      Certificates shall be executed and attested by manual or facsimile signature
      on
      behalf of the Paying Agent by an authorized signatory. Certificates bearing
      the
      manual or facsimile signatures of individuals who were at any time the proper
      officers of the Paying Agent  shall bind the Paying Agent,
      notwithstanding that such individuals or any of them have ceased to hold such
      offices prior to the execution, authentication and delivery of such Certificates
      or did not hold such offices at the date of such Certificates. No Certificate
      shall be entitled to any benefit under this Agreement or be valid for any
      purpose, unless there appears on such Certificate a certificate of
      authentication substantially in the form provided herein executed by the
      Authenticating Agent by manual signature, and such certificate of authentication
      shall be conclusive evidence, and the only evidence, that such Certificate
      has
      been duly authenticated and delivered hereunder. All Certificates shall be
      dated
      the date of their authentication.

     

    (b)  The
      Book-Entry Certificates shall initially be issued as one or more Certificates
      held by Book-Entry Custodian or, if appointed to hold such Certificates as
      provided below, the Depository and registered in the name of the Depository
      or
      its nominee and, except as provided below, registration of such Certificates
      may
      not be transferred by the Certificate Registrar except to another Depository
      that agrees to hold such Certificates for the respective Certificate Owners
      with
      Ownership Interests therein. The Certificate Owners shall hold their respective
      Ownership Interests in and to such Certificates through the book-entry
      facilities of the Depository and, except as provided below, shall not be
      entitled to definitive, fully registered Certificates (“Definitive
      Certificates”) in respect of such Ownership Interests. All transfers by
      Certificate Owners of their respective Ownership Interests in the Book- Entry
      Certificates shall be made in accordance with the procedures established by
      the
      Depository Participant or brokerage firm representing such Certificate Owner.
      Each Depository Participant shall only transfer the Ownership Interests in
      the
      Book-Entry Certificates of Certificate Owners it represents or of brokerage
      firms for which it acts as agent in accordance with the Depository’s normal
      procedures. The Paying Agent is hereby initially appointed as the Book-Entry
      Custodian and hereby agrees to act as such in accordance herewith and in
      accordance with the agreement that it has with the Depository authorizing it
      to
      act as such. The Book-Entry Custodian may, and if it is no longer qualified
      to
      act as such, the Book-Entry Custodian shall, appoint, by a written instrument
      delivered to the Depositor, the Master Servicer and the Trust Administrator
      and
      any other transfer agent (including the Depository or any successor Depository)
      to act as Book-Entry Custodian under such conditions as the predecessor
      Book-Entry Custodian and the Depository or any successor Depository may
      prescribe, provided that the predecessor Book-Entry Custodian shall not be
      relieved of any of its duties or responsibilities by reason of any such
      appointment of other than the Depository. If the Paying Agent resigns or is
      removed in accordance with the terms hereof, the successor Paying Agent or,
      if
      it so elects, the Depository shall immediately succeed to its predecessor’s
      duties as Book-Entry Custodian. The Depositor shall have the right to inspect,
      and to obtain copies of, any Certificates held as Book-Entry Certificates by
      the
      Book-Entry Custodian.

     

    The
      Trustee, the Trust Administrator, the Master Servicer, the Paying Agent, the
      Authenticating Agent, the Certificate Registrar and the Depositor may for all
      purposes (including the making of payments due on the Book-Entry Certificates)
      deal with the Depository as the authorized representative of the Certificate
      Owners with respect to the Book-Entry Certificates for the purposes of
      exercising the rights of Certificateholders hereunder. The rights of Certificate
      Owners with respect to the Book-Entry Certificates shall be limited to those
      established by law and agreements between such Certificate Owners and the
      Depository Participants and brokerage firms representing such Certificate
      Owners. Multiple requests and directions from, and votes of, the Depository
      as
      Holder of the Book-Entry Certificates with respect to any particular matter
      shall not be deemed inconsistent if they are made with respect to different
      Certificate Owners. The Paying Agent may establish a reasonable record date
      in
      connection with solicitations of consents from or voting by Certificateholders
      and shall give notice to the Depository of such record date.

     

    If
      (i)(A)
      the Depositor advises the Trust Administrator, the Paying Agent and the
      Certificate Registrar in writing that the Depository is no longer willing or
      able to properly discharge its responsibilities as Depository, and (B) the
      Depositor is unable to locate a qualified successor or (ii) after the occurrence
      of a Master Servicer Event of Default, Certificate Owners representing in the
      aggregate not less than 51% of the Ownership Interests of the Book-Entry
      Certificates advise the Trust Administrator, the Paying Agent and the
      Certificate Registrar through the Depository, in writing, that the continuation
      of a book-entry system through the Depository is no longer in the best interests
      of the Certificate Owners, the Certificate Registrar shall notify all
      Certificate Owners, through the Depository, of the occurrence of any such event
      and of the availability of Definitive Certificates to Certificate Owners
      requesting the same. Upon surrender to the Certificate Registrar of the Book-
      Entry Certificates by the Book-Entry Custodian or the Depository, as applicable,
      accompanied by registration instructions from the Depository for registration
      of
      transfer, the Paying Agent shall issue the Definitive Certificates. Such
      Definitive Certificates will be issued in minimum denominations of $100,000,
      except that any beneficial ownership that was represented by a Book-Entry
      Certificate in an amount less than $100,000 immediately prior to the issuance
      of
      a Definitive Certificate shall be issued in a minimum denomination equal to
      the
      amount represented by such Book-Entry Certificate. None of the Depositor, the
      Master Servicer, the Trust Administrator, the Authenticating Agent, the Paying
      Agent, the Certificate Registrar nor the Trustee shall be liable for any delay
      in the delivery of such instructions and may conclusively rely on, and shall
      be
      protected in relying on, such instructions. Upon the issuance of Definitive
      Certificates all references herein to obligations imposed upon or to be
      performed by the Depository shall be deemed to be imposed upon and performed
      by
      the Certificate Registrar and the Paying Agent, to the extent applicable with
      respect to such Definitive Certificates, and the Certificate Registrar and
      the
      Paying Agent shall recognize the Holders of the Definitive Certificates as
      Certificateholders hereunder.

                5.02  

            	
              Registration
                of Transfer and Exchange of
                Certificates.

            


    

     

    (a)  The
      Certificate Registrar shall cause to be kept at one of the offices or agencies
      to be appointed by the Trust Administrator in accordance with the provisions
      of
      Section 8.12 a Certificate Register for the Certificates in which, subject
      to
      such reasonable regulations as it may prescribe, the Certificate Registrar
      shall
      provide for the registration of Certificates and of transfers and exchanges
      of
      Certificates as herein provided.

     

    (b)  No
      transfer of any Private Certificate or Ownership Interest therein shall be
      made
      unless that transfer is made pursuant to an effective registration statement
      under the Securities Act of 1933, as amended (the “1933 Act”), and an effective
      registration or qualification under applicable state securities laws, or is
      made
      in a transaction that does not require such registration or qualification.
      In
      the event that such a transfer of a Private Certificate is to be made without
      registration or qualification (other than in connection with the initial
      transfer of any such Certificate by the Depositor to an affiliate of the
      Depositor), the Certificate Registrar shall require, receipt of written
      certifications from the Certificateholder desiring to effect the transfer and
      from such Certificateholder’s prospective transferee, substantially in the forms
      attached hereto as Exhibit F-1, or in the case of any Definitive Certificate,
      an
      opinion of Counsel satisfactory to it that such transfer may be made without
      such registration (which Opinion of Counsel shall not be an expense of the
      Trust
      Fund or of the Depositor, the  Trustee, the Trust Administrator, the
      Certificate Registrar, the Authenticating Agent , the Paying Agent, the Master
      Servicer in its capacity as such or any Sub-Servicer), together with copies
      of
      the written certification(s) of the Certificateholder desiring to effect the
      transfer and/or such Certificateholder’s prospective transferee upon which such
      Opinion of Counsel is based, if any.   In the event of any such
      transfer of any Ownership Interest in any Private Certificate that is a
      Book-Entry Certificate, except with respect to the initial transfer of any
      such
      Certificate by the Depositor, such transfer shall be required to be made in
      reliance upon Rule 144A under the 1933 Act, and the transferor will be deemed
      to
      have made each of the representations and warranties set forth on Exhibit F-1
      hereto in respect of such interest as if it was evidenced by a Definitive
      Certificate and the transferee will be deemed to have made each of the
      representations and warranties set forth on Exhibit F-1 hereto in respect of
      such interest as if it was evidenced by a Definitive
      Certificate.  None of the Depositor or the Trustee is obligated to
      register or qualify any such Certificates under the 1933 Act or any other
      securities laws or to take any action not otherwise required under this
      Agreement to permit the transfer of such Certificates without registration
      or
      qualification. Any Certificateholder desiring to effect the transfer of any
      such
      Certificate or Ownership Interest therein shall, and does hereby agree to,
      indemnify the Trustee, the Trust Administrator, the Certificate Registrar,
      the
      Paying Agent, the Authenticating Agent, the Master Servicer and the Depositor
      against any liability that may result if the transfer is not so exempt or is
      not
      made in accordance with such federal and state laws.

     

    (c)  (i)  No
      transfer of a Residual Certificate or any interest therein shall be made to
      any
      Plan subject to ERISA or Section 4975 of the Code, any Person acting, directly
      or indirectly, on behalf of any such Plan or any Person acquiring such
      Certificates with “Plan Assets” of a Plan within the meaning of the DOL
      Regulations, as modified by Section 3(42) of ERISA (“Plan Assets”) as certified
      by such transferee in the form of Exhibit G, unless the Certificate Registrar
      is
      provided with an Opinion of Counsel on which the Certificate Registrar, the
      Depositor, the Trustee, the Trust Administrator, the Paying Agent, the
      Authenticating Agent and the Master Servicer may rely, to the effect that the
      purchase and holding of such Certificates will be permissible under applicable
      law, ERISA and the Code, will not constitute or result in any non-exempt
      prohibited transaction under ERISA or Section 4975 of the Code and will not
      subject the Depositor, the Master Servicer, the Trustee, the Trust
      Administrator, the Paying Agent, the Authenticating Agent, the Certificate
      Registrar or the Trust Fund to any obligation or liability (including
      obligations or liabilities under ERISA or Section 4975 of the Code) in addition
      to those undertaken in this Agreement, which Opinion of Counsel shall not be
      an
      expense of the Depositor, the Master Servicer, the Trustee, the Trust
      Administrator, the Paying Agent, the Authenticating Agent, the Certificate
      Registrar or the Trust Fund. In lieu of such Opinion of Counsel, any prospective
      Transferee of such Certificates may provide a certification in the form of
      Exhibit G to this Agreement (or other form acceptable to the Depositor, the
      Trustee, the Trust Administrator, the Certificate Registrar, the Paying Agent,
      the Authenticating Agent and the Master Servicer), which the Certificate
      Registrar may rely upon without further inquiry or investigation. Neither a
      certification nor an Opinion of Counsel will be required in connection with
      the
      initial transfer of any such Certificate by the Depositor to an Affiliate of
      the
      Depositor (in which case, the Depositor or any Affiliate thereof shall have
      deemed to have represented that such Affiliate is not a Plan or a Person
      investing Plan Assets) and the Certificate Registrar shall be entitled to
      conclusively rely upon a representation (which, upon the request of the
      Certificate Registrar, shall be a written representation) from the Depositor
      of
      the status of such transferee as an affiliate of the Depositor.

     

    (ii)  Each
      beneficial owner of a Subordinate Certificate or any interest therein shall
      be
      deemed to have represented, by virtue of its acquisition and holding of such
      Certificate or interest therein, that either (A) it is not a Plan or investing
      with Plan Assets, (B) other than with respect to a Class 1-B4 Certificate,
      Class
      1-B5 Certificate, Class 1-B6 Certificate, Class 2-B4 Certificate, Class 2-B5
      Certificate or Class 2-B6 Certificate, it has acquired and is holding such
      Certificate in reliance on the Underwriter’s Exemption granted by the Department
      of Labor on April 18, 1991 as Prohibited Transaction Exemption (“PTE”) 91-23 at
      56 F.R. 15936 and amended on July 21, 1997 as PTE 97-34 at 62 F.R. 39021 and
      further amended on November 13, 2000 by PTE 2000-58 at 65 F.R. 67765 and on
      August 22, 2002 by PTE 2002-41 at 67 F.R. 54487 (“Underwriter’s Exemption”), and
      that it understands that there are certain conditions to the availability of
      the
      Underwriter’s Exemption, including that the certificate must be rated, at the
      time of purchase, not lower than “BBB-” (or its equivalent) by Fitch, Moody’s or
      S&P and it will represent that it is an “accredited investor” as defined in
      Rule 501(a)(1) of Regulation D under the Securities Act and will obtain a
      representation from any transferee that such transferee is an accredited
      investor so long as it is required to obtain a representation regarding
      compliance with the Securities Act, or (C) (i) it is an insurance company,
      (ii)
      the source of funds used to acquire or hold the Certificate or interest therein
      is an “insurance company general account,” as defined in Prohibited Transaction
      Class Exemption (“PTCE”) 95-60, and (iii) the conditions in Sections I and III
      of PTCE 95-60 have been satisfied.

     

    (iii)  If
      any
      Certificate or any interest therein is acquired or held in violation of the
      provisions of the preceding two paragraphs, the next preceding permitted
      beneficial owner will be treated as the beneficial owner of that Certificate
      retroactive to the date of transfer to the purported beneficial owner. Any
      purported beneficial owner whose acquisition or holding of any such Certificate
      or interest therein was effected in violation of the provisions of the preceding
      two paragraphs shall indemnify and hold harmless the Depositor, the Master
      Servicer, the Trustee, the Trust Administrator, the Certificate Registrar,
      the
      Paying Agent, the Authenticating Agent and the Trust Fund from and against
      any
      and all liabilities, claims, costs or expenses incurred by those parties as
      a
      result of that acquisition or holding.

     

    (d)  (i)  Each
      Person who has or who acquires any Ownership Interest in a Residual Certificate
      shall be deemed by the acceptance or acquisition of such Ownership Interest
      to
      have agreed to be bound by the following provisions and to have irrevocably
      authorized the Paying Agent or its designee under clause (iii)(A) below to
      deliver payments to a Person other than such Person and to negotiate the terms
      of any mandatory sale under clause (iii)(B) below and to execute all instruments
      of Transfer and to do all other things necessary in connection with any such
      sale. The rights of each Person acquiring any Ownership Interest in a Residual
      Certificate are expressly subject to the following provisions:

     

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

     

    (B)  In
      connection with any proposed Transfer of any Ownership Interest in a Residual
      Certificate, the Certificate Registrar shall require delivery to it and shall
      not register the Transfer of any Residual Certificate until its receipt of
      an
      affidavit and agreement (a “Transfer Affidavit and Agreement”), in the form
      attached hereto as Exhibit F-2, from the proposed Transferee, in form and
      substance satisfactory to the Certificate Registrar, representing and
      warranting, among other things, that such Transferee is a Permitted Transferee,
      that it is not acquiring its Ownership Interest in the Residual Certificate
      that
      is the subject of the proposed Transfer as a nominee, trustee or agent for
      any
      Person that is not a Permitted Transferee, that for so long as it retains its
      Ownership  Interest in a Residual Certificate, it will endeavor to
      remain a Permitted Transferee, and that it has reviewed the provisions of this
      Section 5.02(d) and agrees to be bound by them.

     

    (C)  Notwithstanding
      the delivery of a Transfer Affidavit and Agreement by a proposed Transferee
      under clause (B) above, if a Responsible Officer of the Certificate Registrar
      who is assigned to this transaction has actual knowledge that the proposed
      Transferee is not a Permitted Transferee, no Transfer of an Ownership Interest
      in a  Residual Certificate to such proposed Transferee shall be
      effected.

     

    (D)  Each
      Person holding or acquiring any Ownership Interest in a Residual Certificate
      shall agree (x) to require a Transfer Affidavit and Agreement from any other
      Person to whom such Person attempts to transfer its Ownership Interest in a
      Residual Certificate and (y) not to transfer its Ownership Interest unless
      it
      provides a transferor affidavit (a “Transferor Affidavit”), in the form attached
      hereto as Exhibit F-2, to the Certificate Registrar stating that, among other
      things, it has no actual  knowledge that such other Person is not a
      Permitted Transferee.

     

    (E)  Each
      Person holding or acquiring an Ownership Interest in a Residual Certificate,
      by
      purchasing an Ownership Interest in such Certificate, agrees to
      give  the Certificate Registrar written notice that it is a
“pass-through interest holder” within the meaning of temporary Treasury
      regulation Section 1.67- 3T(a)(2)(i)(A) immediately upon acquiring an Ownership
      Interest in a Residual Certificate, if it is, or is holding an Ownership
      Interest in a Residual Certificate on behalf of, a “pass-through interest
      holder.”

     

    (ii)  The
      Certificate Registrar will register the Transfer of any Residual Certificate
      only if it shall have received the Transfer Affidavit and Agreement and all
      of
      such other documents as shall have been reasonably required by the Certificate
      Registrar as a condition to such registration. In addition, no Transfer of
      a
      Residual Certificate shall be made unless the Certificate Registrar shall have
      received a representation letter from the Transferee of such Certificate to
      the
      effect that such Transferee is a Permitted Transferee.

     

    (iii)  (A)  If
      any purported Transferee shall become a Holder of a Residual Certificate in
      violation of the provisions of this Section 5.02(d), then the last preceding
      Permitted Transferee shall be restored, to the extent permitted by law, to
      all
      rights as Holder thereof retroactive to the date of registration of such
      Transfer of such Residual Certificate. The Certificate Registrar shall be under
      no liability to any Person for any registration of Transfer of a Residual
      Certificate that is in fact not permitted by this Section 5.02(d) or for making
      any payments due on such Certificate to the Holder thereof or for taking any
      other action with respect to such Holder under the provisions of this
      Agreement.

     

    (B)  If
      any
      purported Transferee shall become a Holder of a Residual Certificate in
      violation of the restrictions in this Section 5.02(d) and to the extent that
      the
      retroactive restoration of the rights of the Holder of such Residual Certificate
      as described in clause (iii)(A) above shall be invalid, illegal or
      unenforceable, then the Certificate Registrar shall have the right, without
      notice to the Holder or any prior Holder of such Residual Certificate, to sell
      such Residual Certificate to a purchaser selected by the Certificate Registrar
      on such terms as the Certificate Registrar may choose. Such purported Transferee
      shall promptly endorse and deliver each Residual Certificate in accordance
      with
      the instructions of the Certificate Registrar. Such purchaser may be the
      Certificate Registrar itself or any Affiliate of the Certificate Registrar.
      The
      proceeds of such sale, net of the commissions (which may
      include  commissions payable to the Certificate Registrar or its
      Affiliates), expenses and taxes due, if any, will be remitted by the Certificate
      Registrar to such purported Transferee. The terms and conditions of any sale
      under this clause (iii)(B) shall be determined in the sole discretion of the
      Certificate Registrar, and the Certificate Registrar shall not be liable to
      any
      Person having an Ownership Interest in a Residual Certificate as a result of
      its
      exercise of such discretion.

     

    (iv)  The
      Trust
      Administrator and the Certificate Registrar shall make available to the Internal
      Revenue Service and those Persons specified by the REMIC Provisions all
      information necessary to compute any tax imposed (A) as a result of the Transfer
      of an Ownership Interest in a Residual Certificate to any Person who is a
      Disqualified Organization, including the information described in Treasury
      regulations sections 1.860D-1(b)(5) and 1.860E-2(a)(5) with respect to the
      “excess inclusions” of such Residual Certificate and (B) as a result of any
      regulated investment company, real estate investment trust, common trust fund,
      partnership, trust, estate or organization described in Section 1381 of the
      Code
      that holds an Ownership Interest in a Residual Certificate having as among
      its
      record holders at any time any Person which is a Disqualified Organization.
      Reasonable compensation for providing such information may be accepted by the
      Trust Administrator and the Certificate Registrar.

     

    (v)  The
      provisions of this Section 5.02(d) set forth prior to this subsection (v) may
      be
      modified, added to or eliminated, provided that there shall have been delivered
      to the Trust Administrator and the Certificate Registrar at the expense of
      the
      party seeking to modify, add to or eliminate any such provision the
      following:

     

    (A)  written
      notification from the Rating Agencies to the effect that the modification,
      addition to or elimination of such provisions will not cause the
      Rating  Agencies to downgrade its then-current ratings of any Class of
      Certificates; and

     

    (B)  an
      Opinion of Counsel, in form and substance satisfactory to the Certificate
      Registrar and the Trust Administrator, to the effect that such modification
      of,
      addition to or elimination of such provisions will not cause any Trust REMIC
      to
      cease to qualify as a REMIC and will not cause (x) any Trust REMIC to be subject
      to an entity-level tax caused by the Transfer of any Residual Certificate to
      a
      Person that is not a Permitted Transferee or (y) a Person other than the
      prospective transferee to be subject to a REMIC-tax caused by the Transfer
      of a
      Residual Certificate to a Person that is not a Permitted
      Transferee.

     

    (e)  Subject
      to the preceding subsections, upon surrender for registration of transfer of
      any
      Certificate at any office or agency of the Certificate Registrar maintained
      for
      such purpose pursuant to Section 8.12, the Certificate Registrar shall give
      notice of such surrender to the Paying Agent and the Authenticating Agent.
      Upon
      receipt of such notice, the Paying Agent shall execute and the Authenticating
      Agent shall authenticate and deliver, in the name of the designated Transferee
      or Transferees, one or more new Certificates of the same Class of a like
      aggregate Percentage Interest.

     

    (f)  At
      the
      option of the Holder thereof, any Certificate may be exchanged for other
      Certificates of the same Class with authorized denominations and a like
      aggregate Percentage Interest, upon surrender of such Certificate to be
      exchanged at any office or agency of the Certificate Registrar maintained for
      such purpose pursuant to Section 8.12. Whenever any Certificates are so
      surrendered for exchange, upon notice from the Certificate Registrar, the Paying
      Agent shall execute, and the Authenticating Agent shall authenticate and
      deliver, the Certificates which the Certificateholder making the exchange is
      entitled to receive. Every Certificate presented or surrendered for transfer
      or
      exchange shall (if so required by the Certificate Registrar) be duly endorsed
      by, or be accompanied by a written instrument of transfer in the form
      satisfactory to the Certificate Registrar duly executed by, the Holder thereof
      or his attorney duly authorized in writing.

     

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

     

    (h)  All
      Certificates surrendered for transfer and exchange shall be canceled and
      destroyed by the Certificate Registrar in accordance with its customary
      procedures.

    If
      (i)
      any mutilated Certificate is surrendered to the Certificate Registrar, or the
      Certificate Registrar receive evidence to its satisfaction of the destruction,
      loss or theft of any Certificate, and (ii) there is delivered to the Certificate
      Registrar, the Trustee and the Trust Administrator such security or indemnity
      as
      may be required by them to save each of them harmless, then, in the absence
      of
      actual knowledge by the Certificate Registrar that such Certificate has been
      acquired by a bona fide purchaser, the Paying Agent shall execute, and the
      Authenticating Agent shall authenticate and deliver, in exchange for or in
      lieu
      of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate
      of the same Class and of like denomination and Percentage Interest. Upon the
      issuance of any new Certificate under this Section, the Certificate Registrar
      may require the payment of a sum sufficient to cover any tax or other
      governmental charge that may be imposed in relation thereto and any other
      expenses (including the fees and expenses of the Certificate Registrar)
      connected therewith. Any replacement Certificate issued pursuant to this Section
      shall constitute complete and indefeasible evidence of ownership in the
      applicable REMIC created hereunder, as if originally issued, whether or not
      the
      lost, stolen or destroyed Certificate shall be found at any time.

                Servicer.

            


    

     

    The
      Depositor and the Master Servicer each shall be liable in accordance herewith
      only to the extent of the obligations specifically imposed by this Agreement
      and
      undertaken hereunder by the Depositor and the Master Servicer
      herein.

                Servicer.

            


    

     

    Subject
      to the following paragraph, the Depositor will keep in full effect its
      existence, rights and franchises as a corporation under the laws of the
      jurisdiction of its incorporation. Subject to the following paragraph, the
      Master Servicer will keep in full effect its existence, rights and franchises
      as
      a corporation under the laws of the jurisdiction of its incorporation and its
      qualification as an approved conventional seller/servicer for Fannie Mae or
      Freddie Mac in good standing. The Depositor and the Master Servicer each will
      obtain and preserve its qualification to do business as a foreign corporation
      in
      each jurisdiction in which such qualification is or shall be necessary to
      protect the validity and enforceability of this Agreement, the Certificates
      or
      any of the Mortgage Loans and to perform its respective duties under this
      Agreement.

     

    The
      Depositor or the Master Servicer may be merged or consolidated with or into
      any
      Person, or transfer all or substantially all of its assets to any Person, in
      which case any Person resulting from any merger or consolidation to which the
      Depositor or the Master Servicer shall be a party, or any Person succeeding
      to
      the business of the Depositor or the Master Servicer, shall be the successor
      of
      the Depositor or the Master Servicer, as the case may be, hereunder, without
      the
      execution or filing of any paper or any further act on the part of any of the
      parties hereto, anything herein to the contrary notwithstanding; provided,
      however, that the successor or surviving Person to the Master Servicer shall
      be
      qualified to service mortgage loans on behalf of Fannie Mae or Freddie Mac;
      and
      provided further that the Rating Agencies’ ratings of the Certificates rated
      thereby and in effect immediately prior to such merger or consolidation will
      not
      be qualified, reduced or withdrawn as a result thereof (as evidenced by a letter
      to such effect from the Rating Agencies).

              Limitation
                on Liability of the Depositor, the Master Servicer and
                Others.

            


    

     

    None
      of
      the Depositor, the Master Servicer or any of the directors, officers, employees
      or agents of the Depositor or the Master Servicer shall be under any liability
      to the Trust Fund or the Certificateholders for any action taken or for
      refraining from the taking of any action in good faith pursuant to this
      Agreement, or for errors in judgment; provided, however, that this provision
      shall not protect the Depositor, the Master Servicer or any such person against
      any breach of warranties, representations or covenants made herein, or against
      any specific liability imposed on the Master Servicer pursuant hereto, or
      against any liability which would otherwise be imposed by reason of willful
      misfeasance, bad faith or negligence in the performance of duties or by reason
      of reckless disregard of obligations and duties hereunder. The Depositor, the
      Master Servicer and any director, officer, employee or agent of the Depositor
      or
      the Master Servicer may rely in good faith on any document of any kind which,
      PRIMA FACIE, is properly executed and submitted by any Person respecting any
      matters arising hereunder. The Depositor, the Master Servicer and any director,
      officer, employee or agent of the Depositor or the Master Servicer shall be
      indemnified and held harmless by the Trust Fund against any loss, liability
      or
      expense incurred in connection with any legal action relating to this Agreement
      or the Certificates, other than any loss, liability or expense to any specific
      Mortgage Loan or Mortgage Loans (except as any such loss, liability or expense
      shall be otherwise reimbursable pursuant to this Agreement) or any loss,
      liability or expense incurred by reason of willful misfeasance, bad faith or
      negligence in the performance of duties hereunder or by reason of reckless
      disregard of obligations and duties hereunder. Neither the Depositor nor the
      Master Servicer shall be under any obligation to appear in, prosecute or defend
      any legal action unless such action is related to its respective duties under
      this Agreement and, in its opinion, does not involve it in any expense or
      liability; provided, however, that each of the Depositor and the Master Servicer
      may in its discretion undertake any such action which it may deem necessary
      or
      desirable with respect to this Agreement and the rights and duties of the
      parties hereto and the interests of the Certificateholders hereunder. In such
      event, unless the Depositor or the Master Servicer acts without the consent
      of
      Holders of Certificates entitled to at least 51% of the Voting Rights (which
      consent shall not be necessary in the case of litigation or other legal action
      by either to enforce their respective rights or defend themselves hereunder),
      the legal expenses and costs of such action and any liability resulting
      therefrom (except any loss, liability or expense incurred by reason of willful
      misfeasance, bad faith or negligence in the performance of duties hereunder
      or
      by reason of reckless disregard of obligations and duties hereunder) shall
      be
      expenses, costs and liabilities of the Trust Fund, and the Depositor (subject
      to
      the limitations set forth above) and the Master Servicer shall be entitled
      to be
      reimbursed therefor from the Collection Account as and to the extent provided
      in
      Section 3.11, any such right of reimbursement being prior to the rights of

              Limitation
                on Resignation of the Master
                Servicer.

            


    

     

    The
      Master Servicer shall not resign from the obligations and duties hereby imposed
      on it except (i) upon determination that its duties hereunder are no longer
      permissible under applicable law or (ii) with the written consent of the Trustee
      and the Trust Administrator, which consent may not be unreasonably withheld,
      with written confirmation from the Rating Agencies (which confirmation shall
      be
      furnished to the Depositor, the Trustee and the Trust Administrator) that such
      resignation will not cause the Rating Agencies to reduce the then current rating
      of the Class A Certificates and provided that a qualified successor has agreed
      to assume the duties and obligations of the Master Servicer hereunder. Any
      such
      determination pursuant to clause (i) of the preceding sentence permitting the
      resignation of the Master Servicer shall be evidenced by an Opinion of Counsel
      to such effect obtained at the expense of the Master Servicer and delivered
      to
      the Trustee and the Trust Administrator. No resignation of the Master Servicer
      shall become effective until the Trustee or a successor servicer shall have
      assumed the Master Servicer’s responsibilities, duties, liabilities (other than
      those liabilities arising prior to the appointment of such successor) and
      obligations under this Agreement.

     

    Except
      as
      expressly provided herein, the Master Servicer shall not assign nor transfer
      any
      of its rights, benefits or privileges hereunder to any other Person, nor
      delegate to or subcontract with, nor authorize or appoint any other Person
      to
      perform any of the duties, covenants or obligations to be performed by the
      Master Servicer hereunder. If, pursuant to any provision hereof, the duties
      of
      the Master Servicer are transferred to a successor master servicer, the entire
      amount of the Servicing Fee and other compensation payable to the Master
      Servicer pursuant hereto shall thereafter be payable to such successor master
      servicer.

                Servicer.

            


    

     

    The
      Master Servicer shall afford (and any Sub-Servicing Agreement shall provide
      that
      each Sub-Servicer shall afford) the Depositor, the Trustee and the Trust
      Administrator, upon reasonable notice, during normal business hours, access
      to
      all records maintained by the Master Servicer (and any such Sub-Servicer) in
      respect of the Master Servicer’s rights and obligations hereunder and access to
      officers of the Master Servicer (and those of any such Sub-Servicer) responsible
      for such obligations. Upon request, the Master Servicer shall furnish to the
      Depositor, the Trustee and the Trust Administrator its (and any such
      Sub-Servicer’s) most recent financial statements of the parent company of the
      Master Servicer and such other information relating to the Master Servicer’s
      capacity to perform its obligations under this Agreement that it possesses.
      Notwithstanding the foregoing, in the case of each Initial Sub-Servicer, such
      access and information described in the preceding two sentences shall be
      required to be provided only to the extent provided in the Sub-Servicing
      Agreement. To the extent such information is not otherwise available to the
      public, the Depositor, the Trustee and the Trust Administrator shall not
      disseminate any information obtained pursuant to the preceding two sentences
      without the Master Servicer’s written consent, except as required pursuant to
      this Agreement or to the extent that it is appropriate to do so (i) in working
      with legal counsel, auditors, taxing authorities or other governmental agencies,
      rating agencies or reinsurers or (ii) pursuant to any law, rule, regulation,
      order, judgment, writ, injunction or decree of any court or governmental
      authority having jurisdiction over the Depositor, the Trustee, the Trust
      Administrator or the Trust Fund, and in either case, the Depositor, the Trustee
      or the Trust Administrator, as the case may be, shall use its best efforts
      to
      assure the confidentiality of any such disseminated non-public information.
      The
      Depositor may, but is not obligated to, enforce the obligations of the Master
      Servicer under this Agreement and may, but is not obligated to, perform, or
      cause a designee to perform, any defaulted obligation of the Master Servicer
      under this Agreement or exercise the rights of the Master Servicer under this
      Agreement; provided that the Master Servicer shall not be relieved of any of
      its
      obligations under this Agreement by virtue of such performance by the Depositor
      or its designee. The Depositor shall not have any responsibility or liability
      for any action or failure to act by the Master Servicer and is not obligated
      to
      supervise the performance of the Master Servicer under this Agreement or
      otherwise.

    “Master
      Servicer Event of Default,” wherever used herein, means any one of the following
      events:

     

    (i)  (A) any
      failure by the Master Servicer to remit to the Paying Agent for distribution
      to
      the Certificateholders any payment (other than a P&I Advance required to be
      made from its own funds on any Master Servicer Remittance Date pursuant to
      Section 4.03) required to be made under the terms of the Certificates and this
      Agreement which continues unremedied for a period of one Business  Day
      after the date upon which written notice of such failure, requiring the same
      to
      be remedied, shall have been given to the Master Servicer (with a copy to the
      Paying Agent ) by the Depositor, the Trust Administrator or the Trustee (in
      which case notice shall be provided by telecopy), or to the Master Servicer,
      the
      Depositor, the Trust Administrator, the Paying Agent and the Trustee by the
      Holders of Certificates entitled to at least 25% of the Voting Rights; or (B)
      any deemed Master Servicer Event of Default caused by a failure by the Master
      Servicer to timely comply with its obligations under Section 3.19 or Section
      3.20 or Section 4.06, taking into account any cure period allowed by the Trustee
      at the direction of the Depositor that may be provided under such sections;
      or

     

    (ii)  any
      failure on the part of the Master Servicer duly to observe or perform in any
      material respect any of the covenants or agreements on the part of the Master
      Servicer contained in the Certificates or in this Agreement which continues
      unremedied for a period of 30 days after the earlier of (i) the date on which
      written notice of such failure, requiring the same to be remedied, shall have
      been given to the Master Servicer by the Depositor, the Trust Administrator
      or
      the Trustee, or to the  Master Servicer, the Depositor, the Trust
      Administrator and the Trustee by the Holders of Certificates entitled to at
      least 25% of the Voting Rights and (ii) actual knowledge of such failure by
      a
      Servicing Officer of the Master Servicer; or

     

    (iii)  a
      decree
      or order of a court or agency or supervisory  authority having
      jurisdiction in the premises in an involuntary case under any present or future
      federal or state bankruptcy, insolvency or similar law or the appointment of
      a
      conservator or  receiver or liquidator in any insolvency, readjustment
      of debt, marshalling of assets and liabilities or similar proceeding, or for
      the
      winding-up or liquidation of its affairs, shall have been entered against the
      Master Servicer and if such proceeding is being contested by the Master Servicer
      in good faith such decree or order shall have remained in force undischarged
      or
      unstayed for a period of 60 consecutive days or results in the entry of an
      order
      for relief or any such adjudication or appointment; or

     

    (iv)  the
      Master Servicer shall consent to the appointment of a conservator or receiver
      or
      liquidator in any insolvency, readjustment of debt, marshalling of assets and
      liabilities or similar proceedings of or relating to the Master Servicer or
      of
      or relating to all or substantially all of its property; or

     

    (v)  the
      Master Servicer shall admit in writing its inability to pay its debts generally
      as they become due, file a petition to take advantage of any applicable
      insolvency or reorganization statute, make an assignment for the benefit of
      its
      creditors, or voluntarily suspend payment of its obligations; or

     

    (vi)  any
      failure of the Master Servicer to make, or of the Paying Agent to make on behalf
      of the Master Servicer, any P&I Advance on any Master Servicer Remittance
      Date required to be made from its own funds pursuant to Section
      4.03.

     

    If
      a
      Master Servicer Event of Default described in clauses (i) through (v) of this
      Section shall occur, then, and in each and every such case, so long as such
      Master Servicer Event of Default shall not have been remedied, the Depositor
      or
      the Trustee may, and at the written direction of the Holders of Certificates
      entitled to at least 51% of Voting Rights, the Trustee shall, by notice in
      writing to the Master Servicer (and to the Depositor if given by the Trustee
      or
      to the Trustee if given by the Depositor), terminate all of the rights and
      obligations of the Master Servicer in its capacity as a Master Servicer under
      this Agreement, to the extent permitted by law, and in and to the Mortgage
      Loans
      and the proceeds thereof. If a Master Servicer Event of Default described in
      clause (vi) hereof shall occur and shall not have been remedied by 1:00 p.m.
      on
      the related Distribution Date, the Paying Agent shall notify the Trustee of
      the
      same, and the Trustee shall be obligated to make such P&I Advance and, then
      so long as such Master Servicer Event of Default shall not have been remedied
      during the applicable time period set forth in clause (vi) above (including
      the
      reimbursement to the Trustee by the Master Servicer, with interest thereon
      at
      the Prime Rate, for any P&I Advance made), the Trustee shall, by notice in
      writing to the Master Servicer and the Depositor, terminate all of the rights
      and obligations of the Master Servicer in its capacity as a Master Servicer
      under this Agreement and in and to the Mortgage Loans and the proceeds thereof.
      On or after the receipt by the Master Servicer of such written notice, all
      authority and power of the Master Servicer under this Agreement, whether with
      respect to the Certificates (other than as a Holder of any Certificate) or
      the
      Mortgage Loans or otherwise, shall pass to and be vested in the Trustee pursuant
      to and under this Section and, without limitation, the Trustee is hereby
      authorized and empowered, as attorney-in-fact or otherwise, to execute and
      deliver on behalf of and at the expense of the Master Servicer, any and all
      documents and other instruments and to do or accomplish all other acts or things
      necessary or appropriate to effect the purposes of such notice of termination,
      whether to complete the transfer and endorsement or assignment of the Mortgage
      Loans and related documents, or otherwise. The Master Servicer agrees, at its
      sole cost and expense, promptly (and in any event no later than ten Business
      Days subsequent to such notice) to provide the Trustee with all documents and
      records requested by it to enable it to assume the Master Servicer’s functions
      under this Agreement, and to cooperate with the Trustee in effecting the
      termination of the Master Servicer’s responsibilities and rights under this
      Agreement, including, without limitation, the transfer within one Business
      Day
      to the Trustee for administration by it of all cash amounts which at the time
      shall be or should have been credited by the Master Servicer to the Collection
      Account held by or on behalf of the Master Servicer, the Distribution Account
      or
      any REO Account or Servicing Account held by or on behalf of the Master Servicer
      or thereafter be received with respect to the Mortgage Loans or any REO Property
      serviced by the Master Servicer (provided, however, that the Master Servicer
      shall continue to be entitled to receive all amounts accrued or owing to it
      under this Agreement on or prior to the date of such termination, whether in
      respect of P&I Advances or otherwise, and shall continue to be entitled to
      the benefits of Section 6.03, notwithstanding any such termination, with respect
      to events occurring prior to such termination). For purposes of this Section
      7.01, the Trustee shall not be deemed to have knowledge of a Master Servicer
      Event of Default unless a Responsible Officer of the Trustee assigned to and
      working in the Trustee’s Corporate Trust Office has actual knowledge thereof or
      unless written notice of any event which is in fact such a Master Servicer
      Event
      of Default is received by the Trustee and such notice references the
      Certificates, the Trust Fund or this Agreement.

    (a)  On
      and
      after the time the Master Servicer receives a notice of termination, the Trustee
      shall be the successor in all respects to the Master Servicer in its capacity
      as
      Master Servicer under this Agreement, the Master Servicer shall not have the
      right to withdraw any funds from the Collection Account without the consent
      of
      the Trustee and the transactions set forth or provided for herein and shall
      be
      subject to all the responsibilities, duties and liabilities relating thereto
      and
      arising thereafter placed on the Master Servicer (except for any representations
      or warranties of the Master Servicer under this Agreement, the responsibilities,
      duties and liabilities contained in Section 2.03(c) and its obligation to
      deposit amounts in respect of losses pursuant to Section 3.12) by the terms
      and
      provisions hereof including, without limitation, the Master Servicer’s
      obligations to make P&I Advances pursuant to Section 4.03; provided,
      however, that if the Trustee is prohibited by law or regulation from obligating
      itself to make advances regarding delinquent mortgage loans, then the Trustee
      shall not be obligated to make P&I Advances pursuant to Section 4.03; and
      provided further, that any failure to perform such duties or responsibilities
      caused by the Master Servicer’s failure to provide information required by
      Section 7.01 shall not be considered a default by the Trustee as successor
      to
      the Master Servicer hereunder. As compensation therefor, the Trustee shall
      be
      entitled to the Servicing Fees and all funds relating to the Mortgage Loans
      to
      which the Master Servicer would have been entitled if it had continued to act
      hereunder (other than amounts which were due or would become due to the Master
      Servicer prior to its termination or resignation). Notwithstanding the above,
      the Trustee may, if it shall be unwilling to so act, or shall, if it is unable
      to so act or if it is prohibited by law from making advances regarding
      delinquent mortgage loans, or if the Holders of Certificates entitled to at
      least 51% of the Voting Rights so request in writing to the Trustee, promptly
      appoint or petition a court of competent jurisdiction to appoint, an established
      mortgage loan servicing institution acceptable to the Rating Agencies and having
      a net worth of not less than $15,000,000 as the successor to the Master Servicer
      under this Agreement in the assumption of all or any part of the
      responsibilities, duties or liabilities of the Master Servicer under this
      Agreement. No appointment of a successor to the Master Servicer under this
      Agreement shall be effective until the assumption by the successor of all of
      the
      Master Servicer’s responsibilities, duties and liabilities hereunder. In
      connection with such appointment and assumption described herein, the Trustee
      may make such arrangements for the compensation of such successor out of
      payments on Mortgage Loans as it and such successor shall agree; provided,
      however, that no such compensation shall be in excess of that permitted the
      Master Servicer as such hereunder. The Depositor, the Trustee and such successor
      shall take such action, consistent with this Agreement, as shall be necessary
      to
      effectuate any such succession. Pending appointment of a successor to the Master
      Servicer under this Agreement, the Trustee shall act in such capacity as
      hereinabove provided.

     

    (b)  In
      connection with the termination or resignation of the Master Servicer hereunder,
      either (i) the successor servicer, including the Trustee, if the Trustee is
      acting as successor Master Servicer, shall  represent and warrant that
      it is a member of MERS in good standing and shall agree to comply in all
      material respects with the rules and procedures of MERS in connection with
      the
      servicing of the Mortgage Loans that are registered with MERS, in which case
      the
      predecessor Master Servicer shall cooperate with the successor Master Servicer
      in causing MERS to revise its records to reflect the transfer of servicing
      to
      the successor Master Servicer as necessary under MERS’ rules and regulations, or
      (ii) the predecessor Master Servicer shall cooperate with the successor Master
      Servicer in causing MERS to execute and deliver an assignment of Mortgage in
      recordable form to transfer the Mortgage from MERS to the Trustee and to execute
      and deliver such other notices, documents and other instruments as may be
      necessary or desirable to effect a transfer of such Mortgage Loan or servicing
      of such Mortgage Loan on the MERS® System to the successor Master Servicer. The
      predecessor Master Servicer shall file or cause to be filed any such assignment
      in the appropriate recording office. The predecessor Master Servicer shall
      bear
      any and all fees of MERS, costs of preparing any assignments of Mortgage, and
      fees and costs of filing any assignments of Mortgage that may be required under
      this Section 7.02(b).

      only such duties as are specifically set forth in this Agreement. During a
      Master Servicer Event of Default, the Trustee shall exercise such of the rights
      and powers vested in it by this Agreement, and use the same degree of care
      and
      skill in their exercise as a prudent person would exercise or use under the
      circumstances in the conduct of such person’s own affairs. Any permissive right
      of the Trustee, the Trust Administrator, the Paying Agent, the Certificate
      Registrar or the Authenticating Agent enumerated in this Agreement shall not
      be
      construed as a duty.

     

    Each

      the Trustee, the Trust Administrator, the Paying Agent, the Certificate
      Registrar and the Authenticating Agent, upon receipt of all resolutions,
      certificates, statements, opinions, reports, documents, orders or other
      instruments furnished to it, which are specifically required to be furnished
      pursuant to any provision of this Agreement, shall examine them to determine
      whether they conform to the requirements of this Agreement; provided, however,
      that none of the Trustee, the Trust Administrator, the Paying Agent, the
      Certificate Registrar or the Authenticating Agent will be responsible for the
      accuracy or content of any such resolutions, certificates, statements, opinions,
      reports, documents or other instruments. If any such instrument is found not
      to
      conform to the requirements of this Agreement in a material manner, it shall
      take such action as it deems appropriate to have the instrument corrected,

      or
      the Trust Administrator, as applicable, and appoint a successor trustee or

      administrator (which may be the same Person in the event the Trust Administrator
      resigns or is removed) by written instrument, in duplicate, which instrument
      shall be delivered to the Trustee or Trust Administrator so removed and to

      trustee or trust administrator by written instrument or instruments, in

      one complete set of which instruments shall be delivered to the Depositor,
      one
      complete set to the Trustee or the Trust Administrator, as the case may be,
      so
      removed and one complete set to the successor so appointed. A copy of such
      instrument shall be delivered to the Certificateholders and the Master Servicer
      by the Depositor.

      no
      successor Trust Administrator shall have been appointed and shall have accepted
      appointment within 60 days after the Trust Administrator ceases to be the Trust
      Administrator pursuant to this Section 8.07, then the Trustee shall perform
      the
      duties of the Trust Administrator pursuant to this Agreement. The Trustee shall
      notify the Rating Agencies of any change of Trust Administrator.

      resignation or removal of the Trustee or the Trust Administrator and appointment
      of a successor trustee or trust administrator, as the case may be, pursuant
      to
      any of the provisions of this Section shall not become effective until
      acceptance of appointment by the successor trustee or trust administrator as
      provided in Section 8.08. Notwithstanding the foregoing, in the event the Trust
      Administrator advises the Trustee that it is unable to continue to perform
      its
      obligations pursuant to the terms of this Agreement prior to the appointment
      of
      a successor, the Trustee shall be obligated to perform such obligations until
      a
      new trust administrator is appointed. Such performance shall be without
      prejudice to any claim by a party hereto or beneficiary hereof resulting from
      the Trust Administrator’s breach of its obligations hereunder. As compensation
      therefor, the Trustee shall be entitled to all fees the Trust Administrator
      would have been entitled to if it had continued to act hereunder.

    Any
      successor trustee or trust administrator appointed as provided in Section 8.07
      shall execute, acknowledge and deliver to the Depositor, the Trustee or the
      Trust Administrator, as applicable, and to its predecessor trustee or trust

      without any further act, deed or conveyance, shall become fully vested with
      all
      the rights, powers, duties and obligations of its predecessor hereunder, with
      the like effect as if originally named as trustee or trust administrator herein.
      The predecessor trustee or trust administrator shall deliver to the successor
      trustee or trust administrator all Mortgage Files and related documents and
      statements, as well as all moneys, held by it hereunder and the Depositor and
      the predecessor trustee or trust administrator shall execute and deliver such
      instruments and do such other things as may reasonably be required for more
      fully and certainly vesting and confirming in the successor trustee or trust
      administrator all such rights, powers, duties and obligations.

     

    No
      successor trustee or trust administrator shall accept appointment as provided
      in
      this Section unless at the time of such acceptance such successor trustee or
      trust administrator shall be eligible under the provisions of Section 8.06
      and
      the appointment of such successor trustee or trust administrator shall not
      result in a downgrading of any Class of Certificates by the Rating Agencies,
      as
      evidenced by a letter from the Rating Agencies.

     

    Upon
      acceptance of appointment by a successor trustee or trust administrator as

      to
      mail such notice within 10 days after acceptance of appointment by the successor
      trustee or trust administrator, the successor trustee or trust administrator
      shall cause such notice to be mailed at the expense of the
      Depositor.

    Notwithstanding
      any other provisions hereof, at any time, for the purpose of meeting any legal
      requirements of any jurisdiction in which any part of REMIC I-A or REMIC II-A
      or
      property securing the same may at the time be located, the Master Servicer
      and
      the Trustee acting jointly shall have the power and shall execute and deliver
      all instruments to appoint one or more Persons approved by the Trustee to act
      as
      co-trustee or co-trustees, jointly with the Trustee, or separate trustee or
      separate trustees, of all or any part of REMIC I-A or REMIC II-A, and to vest
      in
      such Person or Persons, in such capacity, such title to REMIC I-A or REMIC
      II-A,
      or any part thereof, and, subject to the other provisions of this Section 8.10,
      such powers, duties, obligations, rights and trusts as the Master Servicer
      and
      the Trustee may consider necessary or desirable. If the Master Servicer shall
      not have joined in such appointment within 15 days after the receipt by it
      of a
      request to do so, or in case a Master Servicer Event of Default shall have
      occurred and be continuing, the Trustee alone shall have the power to make
      such
      appointment. No co-trustee or separate trustee hereunder shall be required
      to
      meet the terms of eligibility as a successor trustee under Section 8.06
      hereunder and no notice to Holders of Certificates of the appointment of
      co-trustee(s) or separate trustee(s) shall be required under Section 8.08
      hereof.

     

    In
      the
      case of any appointment of a co-trustee or separate trustee pursuant to this
      Section 8.10 all rights, powers, duties and obligations conferred or imposed
      upon the Trustee shall be conferred or imposed upon and exercised or performed
      by the Trustee and such separate trustee or co-trustee jointly, except to the
      extent that under any law of any jurisdiction in which any particular act or
      acts are to be performed by the Trustee (whether as Trustee hereunder or as
      successor to the Master Servicer hereunder), the Trustee shall be incompetent
      or
      unqualified to perform such act or acts, in which event such rights, powers,
      duties and obligations (including the holding of title to REMIC I-A or REMIC
      II-A or any portion thereof in any such jurisdiction) shall be exercised and
      performed by such separate trustee or co-trustee at the direction of the
      Trustee.

     

    Any
      notice, request or other writing given to the Trustee shall be deemed to have
      been given to each of the then separate trustees and co-trustees, as effectively
      as if given to each of them. Every instrument appointing any separate trustee
      or
      co-trustee shall refer to this Agreement and the conditions of this Article
      VIII. Each separate trustee and co-trustee, upon its acceptance of the trust
      conferred, shall be vested with the estates or property specified in its
      instrument of appointment, either jointly with the Trustee or separately, as
      may
      be provided therein, subject to all the provisions of this Agreement,
      specifically including every provision of this Agreement relating to the conduct
      of, affecting the liability of, or affording protection to, the Trustee. Every
      such instrument shall be filed with the Trustee.

     

    Any
      separate trustee or co-trustee may, at any time, constitute the Trustee, its
      agent or attorney-in-fact, with full power and authority, to the extent not
      prohibited by law, to do any lawful act under or in respect of this Agreement
      on
      its behalf and in its name. If any separate trustee or co-trustee shall die,
      become incapable of acting, resign or be removed, all of its estates,
      properties, rights, remedies and trusts shall vest in and be exercised by the
      Trustee, to the extent permitted by law, without the appointment of a new or
      successor trustee.

    (ii)  The
      execution and delivery of this Agreement by it, and the performance and
      compliance with the terms of this Agreement by it, will not violate its articles
      of association or bylaws or constitute a default (or an event which, with notice

      breach of, any material agreement or other instrument to which it is a party
      or

      contemplated by this Agreement, has duly authorized the execution, delivery
      and

    (iv)  This
      Agreement, assuming due authorization, execution and delivery by the other

    (v)  It
      is not
      in violation of, and its execution and delivery of this Agreement and its
      performance and compliance with the terms of this Agreement will not constitute
      a violation of, any law, any order or decree of any court or arbiter, or any
      order, regulation or demand of any federal, state or local governmental or
      regulatory authority, which violation, in its good faith and reasonable
      judgment, is likely to affect materially and adversely either the ability of

    (a)  The
      Trust
      Administrator hereby appoints Citibank as Paying Agent and Citibank hereby
      accepts such appointment. The Paying Agent shall hold all amounts deposited
      with
      it by the Trust Administrator or the Master Servicer for payment on the
      Certificates in trust for the benefit of the Certificateholders until the
      amounts are paid to the Certificateholders or otherwise disposed of in
      accordance with this Agreement.

     

    Any
      corporation or national banking association into which the Paying Agent may
      be
      merged in or converted or with which it may be consolidated, or any corporation
      or national banking association resulting from any merger, conversion or
      consolidation to which such Paying Agent shall be a party, or any corporation
      or
      national banking association succeeding to the corporate agency or corporate
      trust business of the Paying Agent, shall continue to be the Paying Agent,
      provided such corporation or national banking association shall be otherwise
      eligible under this section 8.14(a), without the execution or filing of any
      paper or any further act on the part of the Trustee, the Trust Administrator
      or
      the Paying Agent.

     

    The
      Paying Agent may resign at any time by giving written notice thereof to the
      Trustee and the Trust Administrator. The Trust Administrator may at any time
      terminate the Paying Agent by giving written notice thereof to the Paying Agent
      and to the Trustee. Upon receiving such a notice of resignation or upon such
      a
      termination, or in case at any time such Paying Agent shall cease to be eligible
      in accordance with the provisions of this section 8.14(a), the Trust
      Administrator shall appoint a successor and shall mail written notice of such
      appointment by first-class mail, postage prepaid to all Certificateholders
      as
      their names and addresses appear in the Certificate Register and to the Rating
      Agencies. Following the termination or resignation of the Paying Agent and
      prior
      to the appointment of a successor Paying Agent, the Trust Administrator shall
      act as Paying Agent hereunder. Any successor Paying Agent upon acceptance of
      its
      appointment hereunder shall become vested with all the rights, powers and duties
      of its predecessor hereunder, with like effect as if originally named as the
      Paying Agent herein. No successor Paying Agent shall be appointed unless
      eligible under the provisions of this section 8.14(a).

     

    The
      Paying Agent and any successor Paying Agent (i) may not be an Originator, the
      Master Servicer, a subservicer, the Depositor or an affiliate of the Depositor
      unless the Paying Agent is an institutional trust department, (ii) must be
      authorized to exercise corporate trust powers under the laws of its jurisdiction
      of organization, and (iii) must at all times be rated at least “A1” by S&P
      if S&P is a Rating Agency and at least “A/F1” by Fitch if Fitch is a rating
      agency and the equivalent rating by Moody’s, if Moody’s is a Rating
      Agency.

     

    The
      Trust
      Administrator shall pay to the Paying Agent from its own funds reasonable
      compensation for its services hereunder, and such expense of the Trust
      Administrator shall not be payable from the Trust Fund and shall not be
      recoverable by the Trust Administrator from the assets of the Trust Fund
      pursuant to section 8.05 or any other provision of this Agreement.

     

    (b)  The
      Trust
      Administrator hereby appoints Citibank as  Authenticating Agent and
      Citibank hereby accepts such appointment. The Authenticating Agent shall be
      authorized to authenticate the Certificates, and Certificates so authenticated
      shall be entitled to the benefit of this Agreement.

     

    The
      Authenticating Agent shall at all times remain a corporation or national banking
      association organized and doing business under the laws of the United States
      of
      America, any state thereof or the District of Columbia, authorized under such
      laws to act as Authenticating Agent, having a combined capital and surplus
      of
      not less than $15,000,000, authorized under such laws to conduct a trust
      business and subject to supervision or examination by federal or state
      authority. If the Authenticating Agent publishes reports of condition at least
      annually, pursuant to law or to the requirements of said supervising or
      examining authority, then for the purposes of this section 8.14(b), the combined
      capital and surplus of the Authenticating Agent shall be deemed to be its
      combined capital and surplus as set forth in its most recent report of condition
      so published. If at any time an Authenticating Agent shall cease to be eligible
      in accordance with the provisions of this section 8.14(b), such Authenticating
      Agent shall resign immediately in the manner and with the effect specified
      in
      this section 8.14(b).

     

    Any
      corporation or national banking association into which the Authenticating Agent
      may be merged in or converted or with which it may be consolidated, or any
      corporation or national banking association resulting from any merger,
      conversion or consolidation to which such Authenticating Agent shall be a party,
      or any corporation or national banking association succeeding to the corporate
      agency or corporate trust business of the Authenticating Agent, shall continue
      to be the Authenticating Agent, provided such corporation or national banking
      association shall be otherwise eligible under this section 8.14(b), without
      the
      execution or filing of any paper or any further act on the part of the Trustee,
      the Trust Administrator or the Authenticating Agent.

     

    The
      Authenticating Agent may resign at any time by giving written notice thereof
      to
      the Trustee and the Trust Administrator. The Trust Administrator may at any
      time
      terminate the Authenticating Agent by giving written notice thereof to the
      Authenticating Agent and to the Trustee. Upon receiving such a notice of
      resignation or upon such a termination, or in case at any time such
      Authenticating Agent shall cease to be eligible in accordance with the
      provisions of this section 8.14(b), the Trust Administrator shall appoint a
      successor and shall mail written notice of such appointment by first-class
      mail,
      postage prepaid to all Certificateholders as their names and addresses appear
      in
      the Certificate Register. Following the termination or resignation of the
      Authenticating Agent and prior to the appointment of a successor Authenticating
      Agent, the Trust Administrator shall act as Authenticating Agent hereunder.
      Any
      successor Authenticating Agent upon acceptance of its appointment hereunder
      shall become vested with all the rights, powers and duties of its predecessor
      hereunder, with like effect as if originally named as the Authenticating Agent
      herein. No successor Authenticating Agent shall be appointed unless eligible
      under the provisions of this section 8.14(b).

     

    The
      Trust
      Administrator shall pay to the Authenticating Agent from its own funds
      reasonable compensation for its services hereunder, and such expense of the
      Trust Administrator shall not be payable from the Trust Fund and shall not
      be
      recoverable by the Trust Administrator from the assets of the Trust Fund
      pursuant to section 8.05 or any other provision of this Agreement.

     

    (c)  The
      Trust
      Administrator hereby appoints Citibank as Certificate Registrar and Citibank
      hereby accepts such appointment.

     

    Any
      corporation or national banking association into which the Certificate Registrar
      may be merged in or converted or with which it may be consolidated, or any
      corporation or national banking association resulting from any merger,
      conversion or consolidation to which such Certificate Registrar shall be a
      party, or any corporation or national banking association succeeding to the
      corporate agency or corporate trust business of the Certificate Registrar,
      shall
      continue to be the Certificate Registrar, provided such corporation or national
      banking association shall be otherwise eligible under this section 8.14(c),
      without the execution or filing of any paper or any further act on the part
      of
      the Trustee, the Trust Administrator or the Certificate Registrar.

     

    The
      Certificate Registrar may resign at any time by giving written notice thereof
      to
      the Trustee and the Trust Administrator. The Trust Administrator may at any
      time
      terminate the Certificate Registrar by giving written notice thereof to the
      Certificate Registrar and to the Trustee.

     

    Upon
      receiving such a notice of resignation or upon such a termination, or in case
      at
      any time such Certificate Registrar shall cease to be eligible in accordance
      with the provisions of this section 8.14(c), the Trust Administrator shall
      appoint a successor and shall mail written notice of such appointment by
      first-class mail, postage prepaid to all Certificateholders as their names
      and
      addresses appear in the Certificate Register. Following the termination or
      resignation of the Certificate Registrar and prior to the appointment of a
      successor Certificate Registrar, the Trust Administrator shall act as
      Certificate Registrar hereunder. Any successor Certificate Registrar upon
      acceptance of its appointment hereunder shall become vested with all the rights,
      powers and duties of its predecessor hereunder, with like effect as if
      originally named as the Certificate Registrar herein. No successor Certificate
      Registrar shall be appointed unless eligible under the provisions of this
      section 8.14(c).

     

    The
      Trust
      Administrator shall pay to the Certificate Registrar from its own funds
      reasonable compensation for its services hereunder, and such expense of the
      Trust Administrator shall not be payable from the Trust Fund and shall not
      be
      recoverable by the Trust Administrator from the assets of the Trust Fund
      pursuant to section 8.05 or any other provision of this Agreement.

     

    (d)  Notwithstanding
      anything to the contrary herein, in no event shall the Trustee be liable to
      any
      party hereto or to any third party for the performance of any custody-related
      functions with respect to which the applicable Custodian shall fail to take
      action on behalf of the Trustee or, with respect to which the performance of

    (c)  [Reserved].

     

    (d)  The
      related Terminator shall have the right to purchase all of the Group 1 Mortgage
      Loans and each REO Property remaining in REMIC I-A and/or all of the Group
      2
      Mortgage Loans and each REO Property remaining in REMIC II-A pursuant to Section
      9.01(a)(i) or Section 9.01(b)(i), as applicable, no later than the Determination
      Date in the month immediately preceding the Distribution Date on which the
      Group
      1 Certificates or the Group 2 Certificates, as applicable, will be retired;
      provided, however, that the related Terminator, as provided above, may elect
      to
      purchase (i) all of the Group 1 Mortgage Loans and each REO Property remaining
      in REMIC I-A pursuant to Section 9.01(a)(i) only if the aggregate Stated
      Principal Balance of the Group 1 Mortgage Loans and each REO Property remaining

      1%
      of the aggregate Stated Principal Balance of the Group 2 Mortgage Loans at
      the
      Cut-off Date. For federal income tax purposes, the purchase by the related
      Terminator of the Mortgage Loans and the REO Properties underlying the
      Certificates is intended to facilitate a redemption of such Certificates
      pursuant to a “cleanup call” within the meaning of Treasury regulation section
      1.860G-2(j). Notwithstanding the foregoing, the applicable Terminator shall
      have
      the right to transfer, sell or assign its rights to purchase the Mortgage Loans
      and each REO Property remaining in REMIC I-A or REMIC II-A.

     

    (e)  Notice
      of
      the liquidation of any Certificates shall be given promptly by the Paying Agent
      by letter to the related Certificateholders (with a copy to the Trustee and
      the
      Trust Administrator mailed (a) in the event such notice is given in connection
      with the purchase of either the Group 1 Mortgage Loans or the Group 2 Mortgage
      Loans and each related REO Property remaining in REMIC I-A or REMIC II-A, as
      applicable, by the related Terminator, not earlier than the 15th day and not
      later than the 25th day of the month next preceding the month of the final
      distribution on the related Certificates or (b) otherwise during the month
      of
      such final distribution on or before the Determination Date in such month,
      in
      each case specifying (i) the Distribution Date upon which REMIC I-A or REMIC
      II-A, as applicable, will terminate and final payment of the Group 1
      Certificates or the Group 2 Certificates, as applicable, will be made upon
      presentation and surrender of the Certificates at the office of the Certificate
      Registrar therein designated, (ii) the amount of any such final payment, (iii)
      that no interest shall accrue in respect of the Certificates from and after
      the
      Interest Accrual Period relating to the final Distribution Date therefor and
      (iv) that the Record Date otherwise applicable to such Distribution Date is
      not
      applicable, payments being made only upon presentation and surrender of the
      Certificates at the office of the Certificate Registrar. In the event such
      notice is given in connection with the purchase of all of the Group 1 Mortgage
      Loans or the Group 2 Mortgage Loans and each related REO Property remaining
      in
      REMIC I-A or REMIC II-A, as applicable, by the related Terminator, the related
      Terminator shall deliver to the Paying Agent for deposit in the Distribution
      Account (with notice to the Trustee and the Trust Administrator) not later
      than
      the last Business Day of the month next preceding the month in which such
      distribution will be made an amount in immediately available funds equal to
      the
      Group 1 Termination Price or the Group 2 Termination Price, as applicable.
      Upon
      certification to the Trustee by a Servicing Officer of the making of such final
      deposit, the Trustee shall promptly release or cause to be released to the
      related Terminator the Mortgage Files for the remaining Group 1 Mortgage Loans
      or Group 2 Mortgage Loans, as applicable, and the Trustee shall execute all
      assignments, endorsements and other instruments delivered to it which are
      necessary to effectuate such transfer.

     

    (f)  Upon
      receipt of notice by the Paying Agent of the presentation of the Certificates
      by
      the Certificateholders on the related final Distribution Date to the Certificate
      Registrar, the Paying Agent shall distribute to each Certificateholder so
      presenting and surrendering its Certificates the amount otherwise distributable
      on such Distribution Date in accordance with Section 4.01 in respect of the
      Certificates so presented and surrendered. Any funds not distributed to any
      Holder or Holders of Certificates being retired on such Distribution Date
      because of the failure of such Holder or Holders to tender their Certificates
      shall, on such date, be set aside and held in trust by the Paying Agent and
      credited to the account of the appropriate non-tendering Holder or Holders.
      If
      any Certificates as to which notice has been given pursuant to this Section
      9.01
      shall not have been surrendered for cancellation within six months after the
      time specified in such notice, the Paying Agent shall mail a second notice
      to
      the remaining non-tendering Certificateholders to surrender their Certificates
      for cancellation in order to receive the final distribution with respect
      thereto. If within one year after the second notice all such Certificates shall
      not have been surrendered for cancellation, the Paying Agent shall, directly
      or
      through an agent, mail a final notice to remaining related non-tendering
      Certificateholders concerning surrender of their Certificates. The costs and
      expenses of maintaining the funds in trust and of contacting such
      Certificateholders shall be paid out of the assets remaining in the trust funds.
      If within one year after the final notice any such Certificates shall not have
      been surrendered for cancellation, the Paying Agent shall pay to Citigroup
      Global Markets Inc. all such amounts, and all rights of non-tendering
      Certificateholders in or to such amounts shall thereupon cease. No interest
      shall accrue or be payable to any Certificateholder on any amount held in trust
      by the Paying Agent as a result of such Certificateholder’s failure to surrender
      its Certificate(s) for final payment thereof in accordance with this Section
      9.01.

     

    Immediately
      following the deposit of funds in trust hereunder in respect of each of the
      Group 1 Certificates and the Group 2 Certificates, the Trust Fund shall
      terminate. In no event shall the trust created hereby continue beyond the
      earlier of (a) the Latest Possible Maturity Date and (b) expiration of 21 years
      from the death of the last survivor of the descendants of Joseph P. Kennedy,
      the
      late ambassador of the United States to the Court of St. James, living on the
      date hereof.

      Trustee on Form 1066 or other appropriate federal tax or information return
      or
      any appropriate state return for the taxable year ending on the last day of
      the
      calendar year in which the Certificates are issued.

     

    (b)  The
      Closing Date is hereby designated as the “Startup Day” of each REMIC created
      hereunder within the meaning of Section 860G(a)(9) of the Code.

     

    (c)  The
      Trust
      Administrator shall pay any and all expenses relating to any tax audit of the
      Trust Fund (including, but not limited to, any professional fees or any

      involve the Internal Revenue Service or state tax authorities), and shall be

      matter or controversy involving any Trust REMIC and (ii) represent the Trust
      Fund in any administrative or judicial proceeding relating to an examination
      or
      audit by any governmental taxing authority with respect thereto. The Holder
      of

      Administrator shall prepare and the Trustee at the direction of the Trust
      Administrator shall sign and the Trust Administrator shall file all of the
      Tax
      Returns in respect of the REMIC created hereunder. The expenses of preparing

      to the Trust Administrator or its designee such information with respect to
      the
      assets of the Trust Fund as is in its possession and reasonably required by
      the
      Trust Administrator to enable it to perform its obligations under this
      Article.

     

    (e)  The
      Trust
      Administrator shall perform on behalf of any Trust REMIC all reporting and
      other
      tax compliance duties that are the responsibility of the REMIC under the Code,
      the REMIC Provisions or other compliance guidance issued by the Internal Revenue
      Service or any state or local taxing authority including the filing of Form
      8811
      with the Internal Revenue Service within 30 days following the Closing Date.
      Among its other duties, as required by the Code, the REMIC Provisions or other
      such compliance guidance, the Trust Administrator shall provide (i) to any
      Transferor of a Residual Certificate such information as is necessary for the
      application of any tax relating to the transfer of a Residual Certificate to
      any
      Person who is not a Permitted Transferee, (ii) to the Certificateholders such
      information or reports as are required by the Code or the REMIC Provisions
      including reports relating to interest, original issue discount and market
      discount or premium (using the Prepayment Assumption as required) and (iii)
      to
      the Internal Revenue Service the name, title, address and telephone number
      of
      the person who will serve as the representative of any Trust REMIC. The Master
      Servicer shall provide on a timely basis to the Trust Administrator such
      information with respect to the assets of the Trust Fund, including, without
      limitation, the Mortgage Loans, as is in its possession and reasonably required
      by the Trust Administrator to enable it to perform its obligations under this
      subsection. In addition, the Depositor shall provide or cause to be provided
      to
      the Trust Administrator, within ten (10) days after the Closing Date, all
      information or data that the Trust Administrator reasonably determines to be
      relevant for tax purposes as to the valuations and issue prices of the
      Certificates, including, without limitation, the price, yield, Prepayment
      Assumption and projected cash flow of the Certificates.

     

    (f)  The
      Master Servicer, the Trustee and the Trust Administrator shall take such action
      and shall cause any Trust REMIC to take such action as shall be necessary to
      create or maintain the status thereof as a REMIC under the REMIC Provisions.
      The
      Master Servicer, the Trustee and the Trust Administrator shall not take any
      action, cause the Trust Fund to take any action or fail to take (or fail to
      cause to be taken) any action that, under the REMIC Provisions, if taken or
      not
      taken, as the case may be, could (i) endanger the status of any Trust REMIC
      as a
      REMIC or (ii) result in the imposition of a tax upon the Trust Fund (including
      but not limited to the tax on prohibited transactions as defined in Section
      860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in
      Section 860G(d) of the Code) (either such event, an “Adverse REMIC Event”)
      unless the Trustee and the Trust Administrator have received an Opinion of
      Counsel, addressed to the Trustee and the Trust Administrator (at the expense
      of
      the party seeking to take such action but in no event at the expense of the
      Trust Administrator or the Trustee) to the effect that the contemplated action
      will not, with respect to any Trust REMIC, endanger such status or result in
      the
      imposition of such a tax, nor shall the Master Servicer take or fail to take
      any
      action (whether or not authorized hereunder) as to which the Trustee or the
      Trust Administrator has advised it in writing that it has received an Opinion
      of
      Counsel to the effect that an Adverse REMIC Event could occur with respect
      to
      such action. In addition, prior to taking any action with respect to any Trust
      REMIC or its assets, or causing any Trust REMIC to take any action, which is
      not
      contemplated under the terms of this Agreement, the Master Servicer will consult
      with the Trustee and the Trust Administrator or their designee, in writing,
      with
      respect to whether such action could cause an Adverse REMIC Event to occur
      with
      respect to any Trust REMIC, and the Master Servicer shall not take any such
      action or cause any Trust REMIC to take any such action as to which the Trustee
      or the Trust Administrator has advised it in writing that an Adverse REMIC
      Event
      could occur. The Trust Administrator and the Trustee may consult with counsel
      to
      make such written advice, and the cost of same shall be borne by the party
      seeking to take the action not permitted by this Agreement, but in no event
      shall such cost be an expense of the Trustee or the Trust Administrator. At
      all
      times as may be required by the Code, the Trust Administrator, the Trustee
      or
      the Master Servicer will ensure that substantially all of the assets of any
      Trust REMIC will consist of “qualified mortgages” as defined in Section
      860G(a)(3) of the Code and “permitted investments” as defined in Section
      860G(a)(5) of the Code.

     

    (g)  In
      the
      event that any tax is imposed on “prohibited transactions” of the REMIC created
      hereunder as defined in Section 860F(a)(2) of the Code, on the “net income from
      foreclosure property” of the REMIC as defined in Section 860G(c) of the Code, on
      any contributions to the REMIC after the Startup Day therefor pursuant to
      Section 860G(d) of the Code, or any other tax is imposed by the Code or any
      applicable provisions of state or local tax laws, such tax shall be charged
      (i)
      to the Trust Administrator pursuant to Section 10.03 hereof, if such tax arises
      out of or results from a breach by the Trust Administrator of any of its
      obligations under this Article X, (ii) to the Trustee pursuant to Section 10.03
      hereof, if such tax arises out of or results from a breach by the Trustee of
      any
      of its obligations under this Article X, (iii) to the Master Servicer pursuant
      to Section 10.03 hereof, if such tax arises out of or results from a breach
      by
      the Master Servicer of any of its obligations under Article III or this Article
      X, (iv) to the Paying Agent pursuant to Section 10.03 hereof, if such tax arises
      out of or results from a breach by the Paying Agent of any of its obligations
      under this Article X, or otherwise (v) against amounts on deposit in the
      Distribution Account and shall be paid by withdrawal therefrom.

     

    (h)  [Reserved].

     

    (i)  The
      Trust
      Administrator shall, for federal income tax purposes, maintain books and records
      with respect to any Trust REMIC on a calendar year and on an accrual
      basis.

     

    (j)  Following
      the Startup Day, the Master Servicer, the Trustee and the Trust Administrator
      shall not accept any contributions of assets to any Trust REMIC other than
      in
      connection with any Qualified Substitute Mortgage Loan delivered in accordance
      with Section 2.03 unless it shall have received an Opinion of Counsel to the
      effect that the inclusion of such assets in the Trust Fund will not cause the
      REMIC to fail to qualify as a REMIC at any time that any Certificates are
      outstanding or subject the REMIC to any tax under the REMIC Provisions or other
      applicable provisions of federal, state and local law or
      ordinances.

     

    (k)  None
      of
      the Trustee, the Trust Administrator or the Master Servicer shall enter into
      any
      arrangement by which any Trust REMIC will receive a fee or other compensation
      for services nor permit either such REMIC to receive any income from assets
      other than “qualified mortgages” as defined in Section 860G(a)(3) of the Code or
“permitted investments” as defined in Section 860G(a)(5) of the
      Code.

      has received an Opinion of Counsel, addressed to the Trustee and the Trust
      Administrator (at the expense of the party seeking to cause such sale,
      disposition, substitution, acquisition or contribution but in no event at the
      expense of the Trustee or the Trust Administrator) that such sale, disposition,
      substitution, acquisition or contribution will not (a) affect adversely the
      status of any Trust REMIC as a REMIC or (b) cause any Trust REMIC to be subject
      to a tax on “prohibited transactions” or “contributions” pursuant to the REMIC
      Provisions.

              Amendment.

            


    

     

    This
      Agreement may be amended from time to time by the Depositor, the Master
      Servicer, the Trustee, the Paying Agent, the Certificate Registrar, the
      Authenticating Agent and the Trust Administrator without the consent of any
      of
      the Certificateholders, (i) to cure any ambiguity or defect, (ii) to correct,
      modify or supplement any provisions herein (including to give effect to the
      expectations of Certificateholders) or (iii) to make any other provisions with
      respect to matters or questions arising under this Agreement which shall not
      be
      inconsistent with the provisions of this Agreement, provided that such action
      shall not, as evidenced by either (a) an Opinion of Counsel delivered to the
      Trustee and the Trust Administrator or (b) written notice to the Depositor,
      the
      Servicer, the Trustee and the Trust Administrator from the Rating Agencies
      that
      such action will not result in the reduction or withdrawal of the rating of
      any
      outstanding Class of Certificates with respect to which it is a Rating Agency,
      adversely affect in any material respect the interests of any
      Certificateholder.  No amendment shall be deemed to adversely affect
      in any material respect the interests of any Certificateholder who shall have
      consented thereto, and no Opinion of Counsel or Rating Agency confirmation
      shall
      be required to address the effect of any such amendment on any such consenting
      Certificateholder.

     

    This
      Agreement may also be amended from time to time by the Depositor, the Master
      Servicer, the Trustee, the Paying Agent, the Certificate Registrar, the
      Authenticating Agent and the Trust Administrator with the consent of the Holders
      of Certificates entitled to at least 66% of the Voting Rights 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
      Holders of Certificates; provided, however, that no such amendment shall (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 Holder of such Certificate, (ii) adversely affect in any
      material respect the interests of the Holders of any Class of Certificates
      in a
      manner, other than as described in (i), without the consent of the Holders
      of
      Certificates of such Class evidencing at least 66% of the Voting Rights
      allocated to such Class, or (iii) modify the consents required by the
      immediately preceding clauses (i) and (ii) without the consent of the Holders
      of
      all Certificates then outstanding. Notwithstanding any other provision of this
      Agreement, for purposes of the giving or withholding of consents pursuant to
      this Section 11.01, Certificates registered in the name of the Depositor or
      the
      Master Servicer or any Affiliate thereof shall be entitled to Voting Rights
      with
      respect to matters affecting such Certificates.

     

    Notwithstanding
      any contrary provision of this Agreement, the Trust Administrator shall not
      consent to any amendment to this Agreement unless it shall have first received
      an Opinion of Counsel to the effect that such amendment will not result in
      the
      imposition of any tax on any Trust REMIC pursuant to the REMIC Provisions or
      cause any Trust REMIC to fail to qualify as a REMIC at any time that any
      Certificates are outstanding.

     

    Prior
      to
      executing any amendment pursuant to this Section, the Trust Administrator shall
      be entitled to receive an Opinion of Counsel (provided by the Person requesting
      such amendment) to the effect that such amendment is authorized or permitted
      by
      this Agreement.

     

    Promptly
      after the execution of any such amendment the Trust Administrator shall furnish
      a copy of such amendment to each Certificateholder.

     

    It
      shall
      not be necessary for the consent of Certificateholders under this Section 11.01
      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 Trust Administrator may prescribe.

     

    The
      cost
      of any Opinion of Counsel to be delivered pursuant to this Section 11.01 shall
      be borne by the Person seeking the related amendment, but in no event shall
      such
      Opinion of Counsel be an expense of the Trustee or the Trust
      Administrator.

     

    Notwithstanding
      the foregoing, each of the Trustee, the Paying Agent, the Certificate Registrar,
      the Authenticating Agent and Trust Administrator may, but shall not be obligated
      to enter into any amendment pursuant to this Section that affects its rights,
      duties and immunities under this Agreement or otherwise.

      the
      Trust Fund, or the obligations of the parties hereto, nor shall anything herein

      or under or with respect to this Agreement, unless (i) such Holder previously
      shall have given to the Trustee a written notice of default and of the
      continuance thereof, as hereinbefore provided, and (ii) the Holders of
      Certificates entitled to at least 25% of the Voting Rights shall have made
      written request upon the Trustee to institute such action, suit or proceeding
      in
      its own name as Trustee hereunder and shall have offered to the Trustee such
      indemnity satisfactory to it against the costs, expenses and liabilities to
      be
      incurred therein or thereby, and the Trustee, for 15 days after its receipt
      of
      such notice, request and offer of indemnity, shall have neglected or refused
      to
      institute any such action, suit or proceeding. It is understood and intended,
      and expressly covenanted by each Certificateholder with every other
      Certificateholder and the Trustee, that no one or more Holders of Certificates
      shall have any right in any manner whatsoever by virtue of any provision of
      this
      Agreement to affect, disturb or prejudice the rights of the Holders of any
      other
      of such Certificates, or to obtain or seek to obtain priority over or preference
      to any other such Holder, or to enforce any right under this Agreement, except
      in the manner herein provided and for the equal, ratable and common benefit
      of

              Grant
                of Security Interest.

            


    

     

    It
      is the
      express intent of the parties hereto that the conveyance of the Mortgage Loans
      by the Depositor to the Trustee be, and be construed as, a sale of the Mortgage
      Loans by the Depositor and not a pledge of the Mortgage Loans by the Depositor
      to secure a debt or other obligation of the Depositor. However, in the event
      that, notwithstanding the aforementioned intent of the parties, the Mortgage
      Loans are held to be property of the Depositor, then, (a) it is the express
      intent of the parties that such conveyance be deemed a pledge of the Mortgage
      Loans by the Depositor to the Trustee to secure a debt or other obligation
      of
      the Depositor and (b)(1) this Agreement shall also be deemed to be a security
      agreement within the meaning of Articles 8 and 9 of the Uniform Commercial
      Code
      as in effect from time to time in the State of New York; (2) the conveyance
      provided for in Section 2.01 hereof shall be deemed to be a grant by the
      Depositor to the Trustee of a security interest in all of the Depositor’s right,
      title and interest in and to the Mortgage Loans and all amounts payable to
      the
      holders of the Mortgage Loans in accordance with the terms thereof and all
      proceeds of the conversion, voluntary or involuntary, of the foregoing into
      cash, instruments, securities or other property, including without limitation
      all amounts, other than investment earnings, from time to time held or invested
      in the Collection Account and the Distribution Account, whether in the form
      of
      cash, instruments, securities or other property; (3) the obligations secured
      by
      such security agreement shall be deemed to be all of the Depositor’s obligations
      under this Agreement, including the obligation to provide to the
      Certificateholders the benefits of this Agreement relating to the Mortgage Loans
      and the Trust Fund; and (4) notifications to persons holding such property,
      and
      acknowledgments, receipts or confirmations from persons holding such property,
      shall be deemed notifications to, or acknowledgments, receipts or confirmations
      from, financial intermediaries, bailees or agents (as applicable) of the Trustee
      for the purpose of perfecting such security interest under applicable law.
      Accordingly, the Depositor hereby grants to the Trustee a security interest
      in
      the Mortgage Loans and all other property described in clause (2) of the
      preceding sentence, for the purpose of securing to the Trustee the performance
      by the Depositor of the obligations described in clause (3) of the preceding
      sentence. Notwithstanding the foregoing, the parties hereto intend the
      conveyance pursuant to Section 2.01 to be a true, absolute and unconditional
      sale of the Mortgage Loans and assets constituting the Trust Fund by the
      Depositor to the Trustee.

              Intention
                of the Parties and Interpretation.

            


    

     

    Each
      of
      the parties acknowledges and agrees that the purpose of Sections 3.20, 3.21
      and  4.06 of this Agreement is to facilitate compliance by the
      Depositor with the provisions of Regulation AB promulgated by the Commission
      under the 1934 Act (17 C.F.R. §§ 229.1100 - 229.1123), as such may be amended
      from time to time and subject to clarification and interpretive advice as may
      be
      issued by the staff of the Commission from time to time.  Therefore,
      each of the parties agrees that (a) the obligations of the parties hereunder
      shall be interpreted in such a manner as to accomplish that purpose, (b) the
      parties’ obligations hereunder will be supplemented and modified as necessary to
      be consistent with any such amendments, interpretive advice or guidance,
      convention or consensus among active participants in the asset-backed securities
      markets, opinion of counsel, or otherwise in respect of the requirements of
      Regulation AB, (c) the parties shall comply with requests made by the Depositor
      for delivery of additional or different information, to the extent that such
      information is available or reasonably attainable, as the Depositor may
      determine in good faith is necessary to comply with the provisions of Regulation
      AB, and (d) no amendment of this Agreement shall be required to effect any
      such
      changes in the parties’ obligations as are necessary to accommodate evolving
      interpretations of the provisions of Regulation AB; provided, however, that
      any
      such changes shall require the consent of each of the parties
      hereto.

     

    All
      percentages of Voting Rights referred to herein shall be deemed, with respect
      to
      matters affecting the related Collateral Pool and the related Certificates,
      to
      mean percentages of the Voting Rights with respect to such related
      Certificates.

     

    


     

    IN
      WITNESS WHEREOF, the Depositor, the Master Servicer, the Trust Administrator,
      the Paying Agent, the Authenticating Agent, the Certificate Registrar and the
      Trustee have caused their names to be signed hereto by their respective officers

      the terms, provisions and conditions of the Agreement, to which Agreement the

      which such Holder is bound.

      to the terms of the Agreement, distributions will be made on the 25th day of
      each month

      the
      office or agency appointed by the Paying Agent for that purpose as provided
      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      the terms, provisions and conditions of the Agreement, to which Agreement the

      which such Holder is bound.

      to the terms of the Agreement, distributions will be made on the 25th day of
      each month

      available funds to the account of the Person entitled thereto if such Person

      office or agency appointed by the Paying Agent for that purpose as provided
      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      the terms, provisions and conditions of the Agreement, to which Agreement the

      to the terms of the Agreement, distributions will be made on the 25th day of
      each month

      available funds to the account of the Person entitled thereto if such Person

      distribution and only upon presentation and surrender of this Certificate at
      the
      office or agency appointed by the Paying Agent for that purpose as provided
      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    Any
      transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
      the
      Code, any Person acting, directly or indirectly, on behalf of any such Plan
      or
      any Person using “Plan Assets” to acquire this Certificate shall be made in
      accordance with Section 5.02(c) of the Agreement.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    Any
      transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
      the
      Code, any Person acting, directly or indirectly, on behalf of any such Plan
      or
      any Person using “Plan Assets” to acquire this Certificate shall be made in
      accordance with Section 5.02(c) of the Agreement.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    Any
      transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
      the
      Code, any Person acting, directly or indirectly, on behalf of any such Plan
      or
      any Person using “Plan Assets” to acquire this Certificate shall be made in
      accordance with Section 5.02(c) of the Agreement.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      Agreement.  This Certificate is issued under and is subject to the
      terms, provisions and conditions of the Agreement, to which Agreement the Holder
      of this Certificate by virtue of the acceptance hereof assents and by which
      such
      Holder is bound.

      to the terms of the Agreement, distributions will be made on the 25th day of
      each month

      distribution and only upon presentation and surrender of this Certificate at
      the
      office or agency appointed by the Paying Agent for that purpose as provided
      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    No
      transfer of this Certificate shall be made unless the transfer is made to a
      “qualified institutional buyer” as defined under Rule 144A under the Securities
      Act of 1933, as amended (the “1933 Act”), in a transaction that is exempt from
      the registration requirements of the 1933 Act and that does not require
      registration or qualification under applicable state securities laws. In the
      event that a transfer of this Certificate is to be made, the Certificate
      Registrar shall require receipt of written certifications from the Holder of
      the
      Certificate desiring to effect the transfer, and from such Holder's prospective
      transferee, substantially in the forms attached to the Agreement as Exhibit
      F-1.  None of the Depositor or the Trustee is obligated to register or
      qualify the Class of Certificates specified on the face hereof under the 1933
      Act or any other securities law or to take any action not otherwise required
      under the Agreement to permit the transfer of such Certificates without
      registration or qualification. Any Holder desiring to effect a transfer of
      this
      Certificate shall be required to indemnify the Trustee, the Depositor, the
      Trust
      Administrator, the Certificate Registrar, the Paying Agent, the Authenticating
      Agent and the Master Servicer against any liability that may result if the
      transfer is not so exempt or is not made in accordance with such federal and
      state laws.

     

    No
      transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
      the
      Code, any Person acting, directly or indirectly, on behalf of any such Plan
      or
      any Person using “Plan Assets” to acquire this Certificate shall be made except
      in accordance with Section 5.02(c) of the Agreement.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      the terms, provisions and conditions of the Agreement, to which Agreement the

      which such Holder is bound.

      to the terms of the Agreement, distributions will be made on the 25th day of
      each month
      or, if such 25th day is

      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    No
      transfer of this Certificate shall be made unless the transfer is made to a
      “qualified institutional buyer” as defined under Rule 144A under the Securities
      Act of 1933, as amended (the “1933 Act”), in a transaction that is exempt from
      the registration requirements of the 1933 Act and that does not require
      registration or qualification under applicable state securities laws. In the
      event that a transfer of this Certificate is to be made, the Certificate
      Registrar shall require receipt of written certifications from the Holder of
      the
      Certificate desiring to effect the transfer, and from such Holder's prospective
      transferee, substantially in the forms attached to the Agreement as Exhibit
      F-1.  None of the Depositor or the Trustee is obligated to register or
      qualify the Class of Certificates specified on the face hereof under the 1933
      Act or any other securities law or to take any action not otherwise required
      under the Agreement to permit the transfer of such Certificates without
      registration or qualification. Any Holder desiring to effect a transfer of
      this
      Certificate shall be required to indemnify the Trustee, the Depositor, the
      Trust
      Administrator, the Certificate Registrar, the Paying Agent, the Authenticating
      Agent and the Master Servicer against any liability that may result if the
      transfer is not so exempt or is not made in accordance with such federal and
      state laws.

     

    No
      transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
      the
      Code, any Person acting, directly or indirectly, on behalf of any such Plan
      or
      any person using Plan Assets to acquire this Certificate shall be made except
      in
      accordance with Section 5.02(c) of the Agreement.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      formed and sold by

     

    CITIGROUP

      (obtained by dividing the denomination of this Certificate by the aggregate
      Certificate Principal Balance of the Class 1-B6 Certificates as of the Issue
      Date) in that certain beneficial ownership interest evidenced by all the Class
      1-B6 Certificates in the Trust Fund created pursuant to a Pooling and Servicing
      Agreement, dated as specified above (the “Agreement”), among Citigroup Mortgage
      Loan Trust Inc. (hereinafter called the “Depositor,” which term includes any
      successor entity under the Agreement), the Master Servicer, the Trust
      Administrator, Citibank, N.A. and the Trustee, a summary of certain of the
      pertinent provisions of which is set forth hereafter.  To the extent
      not defined herein, the capitalized terms used herein have the meanings assigned
      in the Agreement.  This Certificate is issued under and is subject to
      the terms, provisions and conditions of the Agreement, to which Agreement the
      Holder of this Certificate by virtue of the acceptance hereof assents and by
      which such Holder is bound.

     

    Pursuant
      to the terms of the Agreement, distributions will be made on the 25th day of
      each month
      or, if such 25th day is
      not a
      Business Day, the Business Day immediately following (a “Distribution Date”),
      commencing on the First Distribution Date specified above, to the Person in
      whose name this Certificate is registered on the Record Date, in an amount
      equal
      to the product of the Percentage Interest evidenced by this Certificate and
      the
      amount required to be distributed to the Holders of Class 1-B6 Certificates
      on
      such Distribution Date pursuant to the Agreement.

     

    All

      made
      or caused to be made by the Paying Agent by wire transfer in immediately
      available funds to the account of the Person entitled thereto if such Person
      shall have so notified the Paying Agent in writing at least five Business Days
      prior to the Record Date immediately prior to such Distribution Date or
      otherwise by check mailed by first class mail to the address of the Person
      entitled thereto, as such name and address shall appear on the Certificate

      Certificate will be made after due notice by the Paying Agent of the pendency
      of
      such distribution and only upon presentation and surrender of this Certificate
      at the office or agency appointed by the Paying Agent for that purpose as
      provided in the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee, and
      the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee, nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement and the Trust Fund created thereby shall
      terminate upon payment to the Certificateholders of all amounts held by the
      Trustee and required to be paid to them pursuant to the Agreement following
      the
      earlier of (i) the final payment or other liquidation (or any advance with
      respect thereto) of the last Mortgage Loan and REO Property remaining in the
      Trust Fund and (ii) the purchase by the party designated in the Agreement at
      a
      price determined as provided in the Agreement from the Trust Fund of all the
      Mortgage Loans and all property acquired in respect of such Mortgage Loans.
      The
      Agreement permits, but does not require, the party designated in the Agreement
      to purchase from the Trust Fund all the Mortgage Loans in the Collateral Pool
      relating to this Certificate and all property acquired in respect of any
      Mortgage Loan in such Collateral Pool at a price determined as provided in
      the
      Agreement. The exercise of such right will effect early retirement of the
      Certificates relating to such Collateral Pool; however, such right to purchase
      is subject to the aggregate Stated Principal Balance of the Mortgage Loans
      in
      such Collateral Pool at the time of purchase being less than 1% of the aggregate
      principal balance of the Mortgage Loans in such Collateral Pool as of the
      Cut-off Date.

     

    No
      transfer of this Certificate shall be made unless the transfer is made to a
      “qualified institutional buyer” as defined under Rule 144A under the Securities
      Act of 1933, as amended (the “1933 Act”), in a transaction that is exempt from
      the registration requirements of the 1933 Act and that does not require
      registration or qualification under applicable state securities laws. In the
      event that a transfer of this Certificate is to be made, the Certificate
      Registrar shall require receipt of written certifications from the Holder of
      the
      Certificate desiring to effect the transfer, and from such Holder's prospective
      transferee, substantially in the forms attached to the Agreement as Exhibit
      F-1.  None of the Depositor or the Trustee is obligated to register or
      qualify the Class of Certificates specified on the face hereof under the 1933
      Act or any other securities law or to take any action not otherwise required
      under the Agreement to permit the transfer of such Certificates without
      registration or qualification. Any Holder desiring to effect a transfer of
      this
      Certificate shall be required to indemnify the Trustee, the Depositor, the
      Trust
      Administrator, the Certificate Registrar, the Paying Agent, the Authenticating
      Agent and the Master Servicer against any liability that may result if the
      transfer is not so exempt or is not made in accordance with such federal and
      state laws.

     

    No
      transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
      the
      Code, any Person acting, directly or indirectly, on behalf of any such Plan
      or
      any Person using “Plan Assets” to acquire this Certificate shall be made except
      in accordance with Section 5.02(c) of the Agreement.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

    MORTGAGE
      PASS-THROUGH CERTIFICATE

     

    evidencing
      a beneficial ownership interest in a Trust Fund (the “Trust Fund”) consisting
      primarily of a pool of conventional one- to four-family, adjustable-rate and
      fixed-rate, first lien mortgage loans (the “Mortgage Loans”) formed and sold
      by

     

    CITIGROUP
      MORTGAGE LOAN TRUST INC.

     

    THIS
      CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN CITIGROUP
      MORTGAGE LOAN TRUST INC., THE MASTER SERVICER, THE TRUSTEE, THE TRUST
      ADMINISTRATOR, CITIBANK, N.A. OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER
      THIS CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE GUARANTEED BY ANY AGENCY
      OR INSTRUMENTALITY OF THE UNITED STATES.

     

    This
      certifies that Citigroup Global Markets, Inc. is the registered owner of the
      Percentage Interest evidenced by this Certificate specified above in that
      certain beneficial ownership interest evidenced by all the Class 1-R
      Certificates in the Trust Fund created pursuant to a Pooling and Servicing
      Agreement, dated as specified above (the “Agreement”), among Citigroup Mortgage
      Loan Trust Inc. (hereinafter called the “Depositor,” which term includes any
      successor entity under the Agreement), the Master Servicer, the Trust
      Administrator, Citibank, N.A. and the Trustee, a summary of certain of the
      pertinent provisions of which is set forth hereafter.  To the extent
      not defined herein, the capitalized terms used herein have the meanings assigned
      in the Agreement.  This Certificate is issued under and is subject to
      the terms, provisions and conditions of the Agreement, to which Agreement the
      Holder of this Certificate by virtue of the acceptance hereof assents and by
      which such Holder is bound.

     

    Pursuant
      to the terms of the Agreement, distributions will be made on the 25th day of
      each month
      or, if such 25th day is
      not a
      Business Day, the Business Day immediately following (a “Distribution Date”),
      commencing on the First Distribution Date specified above, to the Person in
      whose name this Certificate is registered on the Record Date, in an amount
      equal
      to the product of the Percentage Interest evidenced by this Certificate and
      the
      amount required to be distributed to the Holders of Class 1-R Certificates
      on
      such Distribution Date pursuant to the Agreement.

     

    All
      distributions to the Holder of this Certificate under the Agreement will be
      made
      or caused to be made by the Paying Agent by wire transfer in immediately
      available funds to the account of the Person entitled thereto if such Person
      shall have so notified the Paying Agent in writing at least five Business Days
      prior to the Record Date immediately prior to such Distribution Date or
      otherwise by check mailed by first class mail to the address of the Person
      entitled thereto, as such name and address shall appear on the Certificate
      Register. Notwithstanding the above, the final distribution on this Certificate
      will be made after due notice by the Paying Agent of the pendency of such
      distribution and only upon presentation and surrender of this Certificate at
      the
      office or agency appointed by the Paying Agent for that purpose as provided
      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A. and the Trustee and
      the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    No
      transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
      the
      Code, any Person acting, directly or indirectly, on behalf of any such Plan
      or
      any Person using “Plan Assets” to acquire this Certificate shall be made except
      in accordance with Section 5.02(c) of the Agreement.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

    


    Prior
      to
      registration of any transfer, sale or other disposition of this Certificate,
      the
      proposed transferee shall provide to the Certificate Registrar (i) an affidavit
      to the effect that such transferee is any Person other than a Disqualified
      Organization or the agent (including a broker, nominee or middleman) of a
      Disqualified Organization, and (ii) a certificate that acknowledges that (A)
      the
      Class 1-R Certificates have been designated as a residual interest in a REMIC,
      (B) it will include in its income a pro rata share of the net income of
      the Trust Fund and that such income may be an “excess inclusion,” as defined in
      the Code, that, with certain exceptions, cannot be offset by other losses or
      benefits from any tax exemption, and (C) it expects to have the financial means
      to satisfy all of its tax obligations including those relating to holding the
      Class R Certificates. Notwithstanding the registration in the Certificate
      Register of any transfer, sale or other disposition of this Certificate to
      a
      Disqualified Organization or an agent (including a broker, nominee or middleman)
      of a Disqualified Organization, such registration shall be deemed to be of
      no
      legal force or effect whatsoever and such Person shall not be deemed to be
      a
      Certificateholder for any purpose, including, but not limited to, the receipt
      of
      distributions in respect of this Certificate.

     

    The
      Holder of this Certificate, by its acceptance hereof, shall be deemed to have
      consented to the provisions of Section 5.02 of the Agreement and to any
      amendment of the Agreement deemed necessary by counsel of the Depositor to
      ensure that the transfer of this Certificate to any Person other than a
      Permitted Transferee or any other Person will not cause any Trust Fund to cease
      to qualify as a REMIC or cause the imposition of a tax upon the
      REMIC.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee, nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement and the Trust Fund created thereby shall
      terminate upon payment to the Certificateholders of all amounts held by the
      Trustee and required to be paid to them pursuant to the Agreement following
      the
      earlier of (i) the final payment or other liquidation (or any advance with
      respect thereto) of the last Mortgage Loan and REO Property remaining in the
      Trust Fund and (ii) the purchase by the party designated in the Agreement at
      a
      price determined as provided in the Agreement from the Trust Fund of all the
      Mortgage Loans and all property acquired in respect of such Mortgage Loans.
      The
      Agreement permits, but does not require, the party designated in the Agreement
      to purchase from the Trust Fund all the Mortgage Loans in the Collateral Pool
      relating to this Certificate and all property acquired in respect of any
      Mortgage Loan in such Collateral Pool at a price determined as provided in
      the
      Agreement. The exercise of such right will effect early retirement of the
      Certificates relating to such Collateral Pool; however, such right to purchase
      is subject to the aggregate Stated Principal Balance of the Mortgage Loans
      in
      such Collateral Pool at the time of purchase being less than 1% of the aggregate
      principal balance of the Mortgage Loans in such Collateral Pool as of the
      Cut-off Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      pertinent provisions of which is set forth hereafter.  To the extent
      not defined herein, the capitalized terms used herein have the meanings assigned
      in the Agreement.  This Certificate is issued under and is subject to
      the terms, provisions and conditions of the Agreement, to which Agreement the
      Holder of this Certificate by virtue of the acceptance hereof assents and by
      which such Holder is bound.

     

    Pursuant
      to the terms of the Agreement, distributions will be made on the 25th day of
      each month
      or, if such 25th day is

      available funds to the account of the Person entitled thereto if such Person

      distribution and only upon presentation and surrender of this Certificate at
      the
      office or agency appointed by the Paying Agent for that purpose as provided
      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      Administrator, Citibank, N.A. and the Trustee, a summary of certain of the
      pertinent provisions of which is set forth hereafter.  To the extent
      not defined herein, the capitalized terms used herein have the meanings assigned
      in the Agreement.  This Certificate is issued under and is subject to
      the terms, provisions and conditions of the Agreement, to which Agreement the
      Holder of this Certificate by virtue of the acceptance hereof assents and by
      which such Holder is bound.

     

    Pursuant
      to the terms of the Agreement, distributions will be made on the 25th day of
      each month
      or, if such 25th day is

      available funds to the account of the Person entitled thereto if such Person

      will be made after due notice by the Paying Agent of the pendency of such
      distribution and only upon presentation and surrender of this Certificate at
      the
      office or agency appointed by the Paying Agent for that purpose as provided
      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      Administrator, Citibank, N.A. and the Trustee, a summary of certain of the
      pertinent provisions of which is set forth hereafter.  To the extent
      not defined herein, the capitalized terms used herein have the meanings assigned
      in the Agreement.  This Certificate is issued under and is subject to
      the terms, provisions and conditions of the Agreement, to which Agreement the
      Holder of this Certificate by virtue of the acceptance hereof assents and by
      which such Holder is bound.

     

    Pursuant
      to the terms of the Agreement, distributions will be made on the 25th day of
      each month
      or, if such 25th day is

      available funds to the account of the Person entitled thereto if such Person

      will be made after due notice by the Paying Agent of the pendency of such
      distribution and only upon presentation and surrender of this Certificate at
      the
      office or agency appointed by the Paying Agent for that purpose as provided
      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      the terms, provisions and conditions of the Agreement, to which Agreement the

      to the terms of the Agreement, distributions will be made on the 25th day of
      each month

      the
      office or agency appointed by the Paying Agent for that purpose as provided
      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder’s attorney duly authorized in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      Loan Trust Inc. (hereinafter called the “Depositor,” which term includes any
      successor entity under the Agreement), the Master Servicer, the Trust
      Administrator, Citibank, N.A. and the Trustee, a summary of certain of the
      pertinent provisions of which is set forth hereafter.  To the extent
      not defined herein, the capitalized terms used herein have the meanings assigned
      in the Agreement.  This Certificate is issued under and is subject to
      the terms, provisions and conditions of the Agreement, to which Agreement the
      Holder of this Certificate by virtue of the acceptance hereof assents and by
      which such Holder is bound.

     

    Pursuant
      to the terms of the Agreement, distributions will be made on the 25th day of
      each month
      or, if such 25th day is
      not a

      commencing on the First Distribution Date specified above, to the Person in
      whose name this Certificate is registered on the Record Date, in an amount
      equal
      to the product of the Percentage Interest evidenced by this Certificate and
      the
      amount required to be distributed to the Holders of Class 2-A3A Certificates
      on

      made
      or caused to be made by the Paying Agent by wire transfer in immediately
      available funds to the account of the Person entitled thereto if such Person
      shall have so notified the Paying Agent in writing at least five Business Days
      prior to the Record Date immediately prior to such Distribution Date or
      otherwise by check mailed by first class mail to the address of the Person
      entitled thereto, as such name and address shall appear on the Certificate
      Register. Notwithstanding the above, the final distribution on this Certificate
      will be made after due notice by the Paying Agent of the pendency of such
      distribution and only upon presentation and surrender of this Certificate at
      the
      office or agency appointed by the Paying Agent for that purpose as provided
      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      Loan Trust Inc. (hereinafter called the “Depositor,” which term includes any
      successor entity under the Agreement), the Master Servicer, the Trust
      Administrator, Citibank, N.A. and the Trustee, a summary of certain of the
      pertinent provisions of which is set forth hereafter.  To the extent
      not defined herein, the capitalized terms used herein have the meanings assigned
      in the Agreement.  This Certificate is issued under and is subject to
      the terms, provisions and conditions of the Agreement, to which Agreement the
      Holder of this Certificate by virtue of the acceptance hereof assents and by
      which such Holder is bound.

     

    Pursuant
      to the terms of the Agreement, distributions will be made on the 25th day of
      each month
      or, if such 25th day is
      not a

      commencing on the First Distribution Date specified above, to the Person in
      whose name this Certificate is registered on the Record Date, in an amount
      equal
      to the product of the Percentage Interest evidenced by this Certificate and
      the
      amount required to be distributed to the Holders of Class 2-A3B Certificates

      made
      or caused to be made by the Paying Agent by wire transfer in immediately
      available funds to the account of the Person entitled thereto if such Person

      will be made after due notice by the Paying Agent of the pendency of such
      distribution and only upon presentation and surrender of this Certificate at
      the
      office or agency appointed by the Paying Agent for that purpose as provided
      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder’s attorney duly authorized in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

    Pursuant
      to the terms of the Agreement, distributions will be made on the 25th day of
      each month
      or, if such 25th day is
      not a

      commencing on the First Distribution Date specified above, to the Person in
      whose name this Certificate is registered on the Record Date, in an amount
      equal

      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    Any
      transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
      the
      Code, any Person acting, directly or indirectly, on behalf of any such Plan
      or
      any Person using “Plan Assets” to acquire this Certificate shall be made in
      accordance with Section 5.02(c) of the Agreement.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      terms, provisions and conditions of the Agreement, to which Agreement the Holder
      of this Certificate by virtue of the acceptance hereof assents and by which
      such
      Holder is bound.

     

    Pursuant
      to the terms of the Agreement, distributions will be made on the 25th day of
      each month
      or, if such 25th day is
      not a

      commencing on the First Distribution Date specified above, to the Person in
      whose name this Certificate is registered on the Record Date, in an amount
      equal
      to the product of the Percentage Interest evidenced by this Certificate and

      made

      available funds to the account of the Person entitled thereto if such Person

      distribution and only upon presentation and surrender of this Certificate at
      the
      office or agency appointed by the Paying Agent for that purpose as provided
      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    Any
      transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
      the
      Code, any Person acting, directly or indirectly, on behalf of any such Plan
      or
      any Person using “Plan Assets” to acquire this Certificate shall be made in
      accordance with Section 5.02(c) of the Agreement.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      the terms, provisions and conditions of the Agreement, to which Agreement the
      Holder of this Certificate by virtue of the acceptance hereof assents and by
      which such Holder is bound.

     

    Pursuant
      to the terms of the Agreement, distributions will be made on the 25th day of
      each month
      or, if such 25th day is
      not a

      commencing on the First Distribution Date specified above, to the Person in
      whose name this Certificate is registered on the Record Date, in an amount
      equal
      to the product of the Percentage Interest evidenced by this Certificate and
      the

      the
      office or agency appointed by the Paying Agent for that purpose as provided
      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee and the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    Any
      transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
      the
      Code, any Person acting, directly or indirectly, on behalf of any such Plan
      or
      any Person using “Plan Assets” to acquire this Certificate shall be made in
      accordance with Section 5.02(c) of the Agreement.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement
      and the Trust Fund created thereby shall terminate upon payment to the
      Certificateholders of all amounts held by the Trustee and required to be paid
      to
      them pursuant to the Agreement following the earlier of (i) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Mortgage
      Loan and REO Property remaining in the Trust Fund and (ii) the purchase by
      the
      party designated in the Agreement at a price determined as
      provided  in the Agreement from the Trust Fund of all the Mortgage
      Loans and all property acquired in respect of such Mortgage Loans. The Agreement
      permits, but does not require, the party designated in the Agreement to purchase
      from the Trust Fund all the Mortgage Loans in the Collateral Pool relating
      to
      this Certificate and all property acquired in respect of any Mortgage Loan
      in
      such Collateral Pool at a price determined as provided in the Agreement. The
      exercise of such right will effect early retirement of the Certificates relating
      to such Collateral Pool; however, such right to purchase is subject to the
      aggregate Stated Principal Balance of the Mortgage Loans in such Collateral
      Pool
      at the time of purchase being less than 1% of the aggregate principal balance
      of
      the Mortgage Loans in such Collateral Pool as of the Cut-off
      Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      (obtained by dividing the denomination of this Certificate by the aggregate
      Certificate Principal Balance of the Class 2-B4 Certificates as of the Issue
      Date) in that certain beneficial ownership interest evidenced by all the Class
      2-B4 Certificates in the Trust Fund created pursuant to a Pooling and Servicing
      Agreement, dated as specified above (the “Agreement”), among Citigroup Mortgage
      Loan Trust Inc. (hereinafter called the “Depositor,” which term includes any
      successor entity under the Agreement), the Master Servicer, the Trust
      Administrator, Citibank, N.A. and the Trustee, a summary of certain of the
      pertinent provisions of which is set forth hereafter.  To the extent
      not defined herein, the capitalized terms used herein have the meanings assigned
      in the Agreement.  This Certificate is issued under and is subject to
      the terms, provisions and conditions of the Agreement, to which Agreement the
      Holder of this Certificate by virtue of the acceptance hereof assents and by
      which such Holder is bound.

     

    Pursuant
      to the terms of the Agreement, distributions will be made on the 25th day of
      each month
      or, if such 25th day is
      not a
      Business Day, the Business Day immediately following (a “Distribution Date”),
      commencing on the First Distribution Date specified above, to the Person in
      whose name this Certificate is registered on the Record Date, in an amount
      equal
      to the product of the Percentage Interest evidenced by this Certificate and
      the
      amount required to be distributed to the Holders of Class 2-B4 Certificates
      on
      such Distribution Date pursuant to the Agreement.

     

    All
      distributions to the Holder of this Certificate under the Agreement will be
      made
      or caused to be made by the Paying Agent by wire transfer in immediately
      available funds to the account of the Person entitled thereto if such Person
      shall have so notified the Paying Agent in writing at least five Business Days
      prior to the Record Date immediately prior to such Distribution Date or
      otherwise by check mailed by first class mail to the address of the Person
      entitled thereto, as such name and address shall appear on the Certificate
      Register.  Notwithstanding the above, the final distribution on this
      Certificate will be made after due notice by the Paying Agent of the pendency
      of
      such distribution and only upon presentation and surrender of this Certificate
      at the office or agency appointed by the Paying Agent for that purpose as
      provided in the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee, and
      the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee, nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement and the Trust Fund created thereby shall
      terminate upon payment to the Certificateholders of all amounts held by the
      Trustee and required to be paid to them pursuant to the Agreement following
      the
      earlier of (i) the final payment or other liquidation (or any advance with
      respect thereto) of the last Mortgage Loan and REO Property remaining in the
      Trust Fund and (ii) the purchase by the party designated in the Agreement at
      a
      price determined as provided in the Agreement from the Trust Fund of all the
      Mortgage Loans and all property acquired in respect of such Mortgage Loans.
      The
      Agreement permits, but does not require, the party designated in the Agreement
      to purchase from the Trust Fund all the Mortgage Loans in the Collateral Pool
      relating to this Certificate and all property acquired in respect of any
      Mortgage Loan in such Collateral Pool at a price determined as provided in
      the
      Agreement. The exercise of such right will effect early retirement of the
      Certificates relating to such Collateral Pool; however, such right to purchase
      is subject to the aggregate Stated Principal Balance of the Mortgage Loans
      in
      such Collateral Pool at the time of purchase being less than 1% of the aggregate
      principal balance of the Mortgage Loans in such Collateral Pool as of the
      Cut-off Date.

     

    No
      transfer of this Certificate shall be made unless the transfer is made to a
      “qualified institutional buyer” as defined under Rule 144A under the Securities
      Act of 1933, as amended (the “1933 Act”), in a transaction that is exempt from
      the registration requirements of the 1933 Act and that does not require
      registration or qualification under applicable state securities laws. In the
      event that a transfer of this Certificate is to be made, the Certificate
      Registrar shall require receipt of written certifications from the Holder of
      the
      Certificate desiring to effect the transfer, and from such Holder's prospective
      transferee, substantially in the forms attached to the Agreement as Exhibit
      F-1.  None of the Depositor or the Trustee is obligated to register or
      qualify the Class of Certificates specified on the face hereof under the 1933
      Act or any other securities law or to take any action not otherwise required
      under the Agreement to permit the transfer of such Certificates without
      registration or qualification. Any Holder desiring to effect a transfer of
      this
      Certificate shall be required to indemnify the Trustee, the Depositor, the
      Trust
      Administrator, the Certificate Registrar, the Paying Agent, the Authenticating
      Agent and the Master Servicer against any liability that may result if the
      transfer is not so exempt or is not made in accordance with such federal and
      state laws.

     

    No
      transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
      the
      Code, any Person acting, directly or indirectly, on behalf of any such Plan
      or
      any person using Plan Assets to acquire this Certificate shall be made except
      in
      accordance with Section 5.02(c) of the Agreement.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      by

     

    CITIGROUP

    This

      (obtained by dividing the denomination of this Certificate by the aggregate
      Certificate Principal Balance of the Class 2-B5 Certificates as of the Issue
      Date) in that certain beneficial ownership interest evidenced by all the Class
      2-B5 Certificates in the Trust Fund created pursuant to a Pooling and Servicing
      Agreement, dated as specified above (the “Agreement”), among Citigroup Mortgage
      Loan Trust Inc. (hereinafter called the “Depositor,” which term includes any
      successor entity under the Agreement), the Master Servicer, the Trust
      Administrator, Citibank, N.A. and the Trustee, a summary of certain of the
      pertinent provisions of which is set forth hereafter.  To the extent
      not defined herein, the capitalized terms used herein have the meanings assigned
      in the Agreement.  This Certificate is issued under and is subject to
      the terms, provisions and conditions of the Agreement, to which Agreement the
      Holder of this Certificate by virtue of the acceptance hereof assents and by
      which such Holder is bound.

     

    Pursuant
      to the terms of the Agreement, distributions will be made on the 25th day of
      each month
      or, if such 25th day is
      not a
      Business Day, the Business Day immediately following (a “Distribution Date”),
      commencing on the First Distribution Date specified above, to the Person in
      whose name this Certificate is registered on the Record Date, in an amount
      equal
      to the product of the Percentage Interest evidenced by this Certificate and
      the
      amount required to be distributed to the Holders of Class 2-B5 Certificates
      on
      such Distribution Date pursuant to the Agreement.

     

    All
      distributions to the Holder of this Certificate under the Agreement will be
      made
      or caused to be made by the Paying Agent by wire transfer in immediately
      available funds to the account of the Person entitled thereto if such Person
      shall have so notified the Paying Agent in writing at least five Business Days
      prior to the Record Date immediately prior to such Distribution Date or
      otherwise by check mailed by first class mail to the address of the Person
      entitled thereto, as such name and address shall appear on the Certificate
      Register.  Notwithstanding the above, the final distribution on this
      Certificate will be made after due notice by the Paying Agent of the pendency
      of
      such distribution and only upon presentation and surrender of this Certificate
      at the office or agency appointed by the Paying Agent for that purpose as
      provided in the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee, and
      the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A., or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement and the Trust Fund created thereby shall
      terminate upon payment to the Certificateholders of all amounts held by the
      Trustee and required to be paid to them pursuant to the Agreement following
      the
      earlier of (i) the final payment or other liquidation (or any advance with
      respect thereto) of the last Mortgage Loan and REO Property remaining in the
      Trust Fund and (ii) the purchase by the party designated in the Agreement at
      a
      price determined as provided in the Agreement from the Trust Fund of all the
      Mortgage Loans and all property acquired in respect of such Mortgage Loans.
      The
      Agreement permits, but does not require, the party designated in the Agreement
      to purchase from the Trust Fund all the Mortgage Loans in the Collateral Pool
      relating to this Certificate and all property acquired in respect of any
      Mortgage Loan in such Collateral Pool at a price determined as provided in
      the
      Agreement. The exercise of such right will effect early retirement of the
      Certificates relating to such Collateral Pool; however, such right to purchase
      is subject to the aggregate Stated Principal Balance of the Mortgage Loans
      in
      such Collateral Pool at the time of purchase being less than 1% of the aggregate
      principal balance of the Mortgage Loans in such Collateral Pool as of the
      Cut-off Date.

     

    No
      transfer of this Certificate shall be made unless the transfer is made to a
      “qualified institutional buyer” as defined under Rule 144A under the Securities
      Act of 1933, as amended (the “1933 Act”), in a transaction that is exempt from
      the registration requirements of the 1933 Act and that does not require
      registration or qualification under applicable state securities laws. In the
      event that a transfer of this Certificate is to be made, the Certificate
      Registrar shall require receipt of written certifications from the Holder of
      the
      Certificate desiring to effect the transfer, and from such Holder's prospective
      transferee, substantially in the forms attached to the Agreement as Exhibit
      F-1.  None of the Depositor or the Trustee is obligated to register or
      qualify the Class of Certificates specified on the face hereof under the 1933
      Act or any other securities law or to take any action not otherwise required
      under the Agreement to permit the transfer of such Certificates without
      registration or qualification. Any Holder desiring to effect a transfer of
      this
      Certificate shall be required to indemnify the Trustee, the Depositor, the
      Trust
      Administrator, the Certificate Registrar, the Paying Agent, the Authenticating
      Agent and the Master Servicer against any liability that may result if the
      transfer is not so exempt or is not made in accordance with such federal and
      state laws.

     

    No
      transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
      the
      Code, any Person acting, directly or indirectly, on behalf of any such Plan
      or
      any person using Plan Assets to acquire this Certificate shall be made except
      in
      accordance with Section 5.02(c) of the Agreement.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      Certificate Principal Balance of the Class 2-B6 Certificates as of the Issue

      2-B6 Certificates in the Trust Fund created pursuant to a Pooling and Servicing
      Agreement, dated as specified above (the “Agreement”), among Citigroup Mortgage
      Loan Trust Inc. (hereinafter called the “Depositor,” which term includes any
      successor entity under the Agreement), the Master Servicer, the Trust
      Administrator, Citibank, N.A. and the Trustee, a summary of certain of the
      pertinent provisions of which is set forth hereafter.  To the extent
      not defined herein, the capitalized terms used herein have the meanings assigned
      in the Agreement.  This Certificate is issued under and is subject to
      the terms, provisions and conditions of the Agreement, to which Agreement the
      Holder of this Certificate by virtue of the acceptance hereof assents and by
      which such Holder is bound.

     

    Pursuant
      to the terms of the Agreement, distributions will be made on the 25th day of
      each month
      or, if such 25th day is
      not a
      Business Day, the Business Day immediately following (a “Distribution Date”),
      commencing on the First Distribution Date specified above, to the Person in
      whose name this Certificate is registered on the Record Date, in an amount
      equal
      to the product of the Percentage Interest evidenced by this Certificate and
      the
      amount required to be distributed to the Holders of Class 2-B6 Certificates
      on

      made
      or caused to be made by the Paying Agent by wire transfer in immediately
      available funds to the account of the Person entitled thereto if such Person
      shall have so notified the Paying Agent in writing at least five Business Days
      prior to the Record Date immediately prior to such Distribution Date or
      otherwise by check mailed by first class mail to the address of the Person
      entitled thereto, as such name and address shall appear on the Certificate
      Register.  Notwithstanding the above, the final distribution on this
      Certificate will be made after due notice by the Paying Agent of the pendency
      of
      such distribution and only upon presentation and surrender of this Certificate
      at the office or agency appointed by the Paying Agent for that purpose as
      provided in the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A., the Trustee, and
      the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A., or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement and the Trust Fund created thereby shall
      terminate upon payment to the Certificateholders of all amounts held by the
      Trustee and required to be paid to them pursuant to the Agreement following
      the
      earlier of (i) the final payment or other liquidation (or any advance with
      respect thereto) of the last Mortgage Loan and REO Property remaining in the
      Trust Fund and (ii) the purchase by the party designated in the Agreement at
      a
      price determined as provided in the Agreement from the Trust Fund of all the
      Mortgage Loans and all property acquired in respect of such Mortgage Loans.
      The
      Agreement permits, but does not require, the party designated in the Agreement
      to purchase from the Trust Fund all the Mortgage Loans in the Collateral Pool
      relating to this Certificate and all property acquired in respect of any
      Mortgage Loan in such Collateral Pool at a price determined as provided in
      the
      Agreement. The exercise of such right will effect early retirement of the
      Certificates relating to such Collateral Pool; however, such right to purchase
      is subject to the aggregate Stated Principal Balance of the Mortgage Loans
      in
      such Collateral Pool at the time of purchase being less than 1% of the aggregate
      principal balance of the Mortgage Loans in such Collateral Pool as of the
      Cut-off Date.

     

    No
      transfer of this Certificate shall be made unless the transfer is made to a
      “qualified institutional buyer” as defined under Rule 144A under the Securities
      Act of 1933, as amended (the “1933 Act”), in a transaction that is exempt from
      the registration requirements of the 1933 Act and that does not require
      registration or qualification under applicable state securities laws. In the
      event that a transfer of this Certificate is to be made, the Certificate
      Registrar shall require receipt of written certifications from the Holder of
      the
      Certificate desiring to effect the transfer, and from such Holder's prospective
      transferee, substantially in the forms attached to the Agreement as Exhibit
      F-1.  None of the Depositor or the Trustee is obligated to register or
      qualify the Class of Certificates specified on the face hereof under the 1933
      Act or any other securities law or to take any action not otherwise required
      under the Agreement to permit the transfer of such Certificates without
      registration or qualification. Any Holder desiring to effect a transfer of
      this
      Certificate shall be required to indemnify the Trustee, the Depositor, the
      Trust
      Administrator, the Certificate Registrar, the Paying Agent, the Authenticating
      Agent and the Master Servicer against any liability that may result if the
      transfer is not so exempt or is not made in accordance with such federal and
      state laws.

     

    No
      transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
      the
      Code, any Person acting, directly or indirectly, on behalf of any such Plan
      or
      any person using Plan Assets to acquire this Certificate shall be made except
      in
      accordance with Section 5.02(c) of the Agreement.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

      primarily of a pool of conventional one- to four-family, adjustable-rate and
      fixed-rate, first lien mortgage loans (the “Mortgage Loans”) formed and sold
      by

     

    CITIGROUP
      MORTGAGE LOAN TRUST INC.

     

    THIS
      CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN CITIGROUP
      MORTGAGE LOAN TRUST INC., THE MASTER SERVICER, THE TRUSTEE, THE TRUST
      ADMINISTRATOR, CITIBANK, N.A. OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER
      THIS CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE GUARANTEED BY ANY AGENCY
      OR INSTRUMENTALITY OF THE UNITED STATES.

     

    This
      certifies that Citigroup Global Markets, Inc. is the registered owner of the
      Percentage Interest evidenced by this Certificate specified above in that
      certain beneficial ownership interest evidenced by all the Class 2-R
      Certificates in the Trust Fund created pursuant to a Pooling and Servicing
      Agreement, dated as specified above (the “Agreement”), among Citigroup Mortgage
      Loan Trust Inc. (hereinafter called the “Depositor,” which term includes any
      successor entity under the Agreement), the Master Servicer, the Trust
      Administrator, Citibank, N.A. and the Trustee, a summary of certain of the
      pertinent provisions of which is set forth hereafter.  To the extent
      not defined herein, the capitalized terms used herein have the meanings assigned
      in the Agreement.  This Certificate is issued under and is subject to
      the terms, provisions and conditions of the Agreement, to which Agreement the
      Holder of this Certificate by virtue of the acceptance hereof assents and by
      which such Holder is bound.

     

    Pursuant
      to the terms of the Agreement, distributions will be made on the 25th day of
      each month
      or, if such 25th day is
      not a
      Business Day, the Business Day immediately following (a “Distribution Date”),
      commencing on the First Distribution Date specified above, to the Person in
      whose name this Certificate is registered on the Record Date, in an amount
      equal
      to the product of the Percentage Interest evidenced by this Certificate and
      the
      amount required to be distributed to the Holders of Class 2-R Certificates
      on
      such Distribution Date pursuant to the Agreement.

     

    All
      distributions to the Holder of this Certificate under the Agreement will be
      made
      or caused to be made by the Paying Agent by wire transfer in immediately
      available funds to the account of the Person entitled thereto if such Person
      shall have so notified the Paying Agent in writing at least five Business Days
      prior to the Record Date immediately prior to such Distribution Date or
      otherwise by check mailed by first class mail to the address of the Person
      entitled thereto, as such name and address shall appear on the Certificate
      Register. Notwithstanding the above, the final distribution on this Certificate
      will be made after due notice by the Paying Agent of the pendency of such
      distribution and only upon presentation and surrender of this Certificate at
      the
      office or agency appointed by the Paying Agent for that purpose as provided
      in
      the Agreement.

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      Mortgage Pass-Through Certificates of the Series specified on the face hereof
      (herein called the “Certificates”) and representing the Percentage Interest
      specified above in the Class of Certificates to which this Certificate
      belongs.

     

    The
      Certificates are limited in right of payment to certain collections and
      recoveries respecting the Mortgage Loans, all as more specifically set forth
      herein and in the Agreement. As provided in the Agreement, withdrawals from
      the
      Collection Account and the Distribution Account may be made from time to time
      for purposes other than distributions to Certificateholders, such purposes
      including reimbursement of advances made, or certain expenses incurred, with
      respect to the Mortgage Loans.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Depositor,
      the
      Master Servicer, the Trust Administrator, Citibank, N.A. and the Trustee and
      the
      rights of the Certificateholders, under the Agreement at any time by the
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A. and
      the
      Trustee with the consent of the Holders of Certificates entitled to at least
      66%
      of the Voting Rights. Any such consent by the Holder of this Certificate shall
      be conclusive and binding on such Holder and upon all future Holders of this
      Certificate and of any Certificate issued upon the transfer hereof or in
      exchange herefor or in lieu hereof whether or not notation of such consent
      is
      made upon this Certificate. The Agreement also permits the amendment thereof,
      in
      certain limited circumstances, without the consent of the Holders of any of
      the
      Certificates.

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      upon
      surrender of this Certificate for registration of transfer at the offices or
      agencies appointed by the Certificate Registrar as provided in the Agreement,
      duly endorsed by, or accompanied by an assignment in the form below or other
      written instrument of transfer in form satisfactory to the Certificate Registrar
      duly executed by, the Holder hereof or such Holder's attorney duly authorized
      in
      writing, and thereupon one or more new Certificates of the same Class in
      authorized denominations evidencing the same aggregate Percentage Interest
      will
      be issued to the designated transferee or transferees.

     

    No
      transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
      the
      Code, any Person acting, directly or indirectly, on behalf of any such Plan
      or
      any Person using “Plan Assets” to acquire this Certificate shall be made except
      in accordance with Section 5.02(c) of the Agreement.

     

    The
      Certificates are issuable in fully registered form only without coupons in
      Classes and denominations representing Percentage Interests specified in the
      Agreement. As provided in the Agreement and subject to certain limitations
      therein set forth, the Certificates are exchangeable for new Certificates of
      the
      same Class in authorized denominations evidencing the same aggregate Percentage
      Interest, as requested by the Holder surrendering the same.  No
      service charge will be made for any such registration of transfer or exchange
      of
      Certificates, but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or other governmental charge that may be imposed
      in
      connection with any transfer or exchange of Certificates.

    


    Prior
      to
      registration of any transfer, sale or other disposition of this Certificate,
      the
      proposed transferee shall provide to the Certificate Registrar (i) an affidavit
      to the effect that such transferee is any Person other than a Disqualified
      Organization or the agent (including a broker, nominee or middleman) of a
      Disqualified Organization, and (ii) a certificate that acknowledges that (A)
      the
      Class 2-R Certificates have been designated as a residual interest in a REMIC,
      (B) it will include in its income a pro rata share of the net income of
      the Trust Fund and that such income may be an “excess inclusion,” as defined in
      the Code, that, with certain exceptions, cannot be offset by other losses or
      benefits from any tax exemption, and (C) it expects to have the financial means
      to satisfy all of its tax obligations including those relating to holding the
      Class R Certificates. Notwithstanding the registration in the Certificate
      Register of any transfer, sale or other disposition of this Certificate to
      a
      Disqualified Organization or an agent (including a broker, nominee or middleman)
      of a Disqualified Organization, such registration shall be deemed to be of
      no
      legal force or effect whatsoever and such Person shall not be deemed to be
      a
      Certificateholder for any purpose, including, but not limited to, the receipt
      of
      distributions in respect of this Certificate.

     

    The
      Holder of this Certificate, by its acceptance hereof, shall be deemed to have
      consented to the provisions of Section 5.02 of the Agreement and to any
      amendment of the Agreement deemed necessary by counsel of the Depositor to
      ensure that the transfer of this Certificate to any Person other than a
      Permitted Transferee or any other Person will not cause any Trust Fund to cease
      to qualify as a REMIC or cause the imposition of a tax upon the
      REMIC.

     

    The
      Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A., the
      Trustee and any agent of the Depositor, the Master Servicer, the Trust
      Administrator, Citibank, N.A. or the Trustee may treat the Person in whose
      name
      this Certificate is registered as the owner hereof for all purposes, and none
      of
      the Depositor, the Master Servicer, the Trust Administrator, Citibank, N.A.,
      the
      Trustee, nor any such agent shall be affected by notice to the
      contrary.

     

    The
      obligations created by the Agreement and the Trust Fund created thereby shall
      terminate upon payment to the Certificateholders of all amounts held by the
      Trustee and required to be paid to them pursuant to the Agreement following
      the
      earlier of (i) the final payment or other liquidation (or any advance with
      respect thereto) of the last Mortgage Loan and REO Property remaining in the
      Trust Fund and (ii) the purchase by the party designated in the Agreement at
      a
      price determined as provided in the Agreement from the Trust Fund of all the
      Mortgage Loans and all property acquired in respect of such Mortgage Loans.
      The
      Agreement permits, but does not require, the party designated in the Agreement
      to purchase from the Trust Fund all the Mortgage Loans in the Collateral Pool
      relating to this Certificate and all property acquired in respect of any
      Mortgage Loan in such Collateral Pool at a price determined as provided in
      the
      Agreement. The exercise of such right will effect early retirement of the
      Certificates relating to such Collateral Pool; however, such right to purchase
      is subject to the aggregate Stated Principal Balance of the Mortgage Loans
      in
      such Collateral Pool at the time of purchase being less than 1% of the aggregate
      principal balance of the Mortgage Loans in such Collateral Pool as of the
      Cut-off Date.

     

    The
      recitals contained herein shall be taken as statements of the Depositor, and
      the
      Trustee assumes no responsibility for their correctness.

     

    Unless
      the certificate of authentication hereon has been executed by the Authenticating
      Agent, by manual signature, this Certificate shall not be entitled to any
      benefit under the Agreement or be valid for any purpose.

     

    IN
      WITNESS WHEREOF, the Paying Agent has caused this Certificate to be duly
      executed.

    ASSESSMENT
      OF COMPLIANCE

     

    


     

    Definitions

    Primary
      Servicer – transaction party having borrower contact

    
      	
               

            	
              Master
                Servicer – aggregator of pool
                assets

            


    

    Trust
      Administrator – waterfall calculator (may be the Trustee, or may be the Master
      Servicer)

    Back-up
      Servicer – named in the transaction (in the event a Back up Servicer becomes the
      Primary Servicer, follow Primary Servicer obligations)

    Custodian
      – safe keeper of pool assets

    Paying
      Agent – distributor of funds to ultimate investor

    Trustee
–
      fiduciary of the transaction

    


    Note:  The
      definitions above describe the essential function that the party performs,
      rather than the party’s title.  So, for example, in a particular
      transaction, the trustee may perform the “paying agent” and “trust
      administrator” functions, while in another transaction, the trust administrator
      may perform these functions.

    


    Where
      there are multiple checks for criteria the attesting party will identify in
      their management assertion that they are attesting only to the portion of the
      distribution chain they are responsible for in the related transaction
      agreements.

      MORTGAGE LOAN PURCHASE AGREEMENT

     



    MORTGAGE
      LOAN PURCHASE AGREEMENT

     

    This
      is a
      Mortgage Loan Purchase Agreement (the “Agreement”), dated February 27, 2007
      between Citigroup Mortgage Loan Trust Inc., a Delaware corporation (the
“Purchaser”) and Citigroup Global Markets Realty Corp., a New York corporation
      (the “Seller”).

     

    Preliminary
      Statement

     

    The
      Seller intends to sell the Mortgage Loans (as hereinafter defined) to the
      Purchaser on the terms and subject to the conditions set forth in this
      Agreement. The Purchaser intends to deposit the Mortgage Loans into a mortgage
      pool comprising the trust fund. The trust fund will be evidenced by a single
      series of mortgage pass-through certificates designated as Series 2007-AR4
      (the
“Certificates”). The Certificates will consist of twenty-three classes of
      certificates.  The Certificates will be issued pursuant to a Pooling
      and Servicing Agreement, dated as of February 1, 2007 (the “Pooling and
      Servicing Agreement”), among the Purchaser as depositor, CitiMortgage, Inc. as
      master servicer (in such capacity, the “Master Servicer”) and as trust
      administrator (in such capacity, the “Trust Administrator”) Citibank, N.A. as
      paying agent, certificate registrar and authenticating agent and U.S. Bank
      Trust
      National Association as trustee (the “Trustee”). Capitalized terms used but not
      defined herein shall have the meanings set forth in the Pooling and Servicing
      Agreement.

     

    The
      parties hereto agree as follows:

     

    Section
      1.  Agreement
      to Purchase. The Seller agrees to sell, and the Purchaser agrees to
      purchase, on or before February 28, 2007 (the “Closing Date”), certain
      adjustable-rate, conventional residential mortgage loans (the “Mortgage Loans”)
      originated by Countrywide Home Loans, Inc. (“Countrywide”), Fifth Third Bank
      (“Fifth Third”), National City Mortgage Co. (“National City”) and Wells Fargo
      Bank, N.A. (“Wells Fargo”, each an “Originator”, and together, the
“Originators”), having an aggregate principal balance as of the close of
      business on February 1, 2007 (the “Cut-off Date”) of $1,181,508,657.73 (the
“Closing Balance”), after giving effect to all payments due on the Mortgage
      Loans on or before the Cut-off Date, whether or not received. 

     

    Notwithstanding
      any of the foregoing, the Seller shall retain its rights against each Originator
      relating to remedies for breaches of loan-level representations and warranties
      and remedies with respect to early payment defaults, if any.

     

    Section
      2.  Mortgage
      Loan Schedule. The Purchaser and the Seller have agreed upon which of the
      mortgage loans owned by the Seller are to be purchased by the Purchaser pursuant
      to this Agreement and the Seller will prepare or cause to be prepared on or
      prior to the Closing Date a final schedule (the “Closing Schedule”) that
      together shall describe such Mortgage Loans and set forth all of the Mortgage
      Loans to be purchased under this Agreement. The Closing Schedule will conform
      to
      the requirements set forth in this Agreement and to the definition of “Mortgage
      Loan Schedule” under the Pooling and Servicing Agreement. The Closing Schedule
      shall be used as the Mortgage Loan Schedule under the Pooling and Servicing
      Agreement and shall be prepared by the Seller based on information provided
      by
      the Originators.

     

    Section
      3.  Consideration.

     

    (a)  In
      consideration for the Mortgage Loans to be purchased hereunder, the Purchaser
      shall, as described in Section 7, pay to or upon the order of the Seller in
      immediately available funds an amount (the “Mortgage Loan Purchase Price”) equal
      to the net sale proceeds of the Certificates, plus accrued
      interest.

     

    (b)  The
      Purchaser or any assignee, transferee or designee of the Purchaser shall be
      entitled to all scheduled payments of principal due after the Cut-off Date,
      all
      other payments of principal due and collected after the Cut-off Date, and all
      payments of interest on the Mortgage Loans allocable to the period after the
      Cut-off Date. All scheduled payments of principal and interest due on or before
      the Cut-off Date and collected after the Cut-off Date shall belong to the
      Seller.

     

    (c)  Pursuant
      to the Pooling and Servicing Agreement, the Purchaser will assign all of its
      right, title and interest in and to the Mortgage Loans, together with its rights
      under this Agreement, to the Trustee for the benefit of the related
      Certificateholders.

     

    Section
      4.  Transfer
      of the Mortgage Loans.

     

    (a)  Possession
      of Mortgage Files.  The Seller does hereby sell, transfer, assign,
      set over and convey to the Purchaser, without recourse but subject to the terms
      of this Agreement, all of its right, title and interest in, to and under the
      Mortgage Loans. The contents of each Mortgage File not delivered to the
      Purchaser or to any assignee, transferee or designee of the Purchaser on or
      prior to the Closing Date are and shall be held in trust by the Seller for
      the
      benefit of the Purchaser or any assignee, transferee or designee of the
      Purchaser. Upon the sale of the Mortgage Loans, the ownership of each Mortgage
      Note, the related Mortgage and the other contents of the related Mortgage File
      is vested in the Purchaser and the ownership of all records and documents with
      respect to each related Mortgage Loan prepared by or that come into the
      possession of the Seller on or after the Closing Date shall immediately vest
      in
      the Purchaser and shall be delivered immediately to the Purchaser or as
      otherwise directed by the Purchaser.

     

    (b)  Delivery
      of Mortgage Loan Documents.  The Seller will, on or prior to the
      Closing Date, deliver or cause to be delivered to the Purchaser or any assignee,
      transferee or designee of the Purchaser each of the following documents for
      each
      Mortgage Loan:

     

    (i)           the
      original Mortgage Note, endorsed in one of the following forms: (i) in the
      name
      of the Trustee or (ii) in blank, in each case, with all prior and intervening
      endorsements showing a complete chain of endorsement from the originator to
      the
      Person so endorsing to the Trustee;

     

    (ii)           the
      original Mortgage with evidence of recording thereon;

     

    (iii)              an
      original Assignment of the Mortgage in recordable form in blank or to the
      Trustee;

     

    (iv)              the
      original recorded Assignment or Assignments of the Mortgage showing a complete
      chain of assignment from the originator to the Person assigning the Mortgage
      in
      blank or to the Trustee as contemplated by the immediately preceding clause
      (iii);

     

    (v)              the
      original of or a copy of each related assumption, modification, consolidation
      or
      extension agreement, with evidence of recording thereon, if any;

     

    (vi)              with
      respect to any Mortgage Loan listed on the Mortgage Loan Schedule
      as  subject to a Primary Mortgage Insurance Policy, the original
      Primary Mortgage Insurance Policy or certificate;

     

    (vii)              the
      original mortgagee title insurance policy or an attorney’s opinion of title
      where customary; and

     

    (viii)              any
      of the following that are in the possession of the Seller or a document
      custodian on its behalf: (A) the original of or a copy of any security
      agreement, chattel mortgage or equivalent document executed in connection with
      the Mortgage or (B) the original of or a copy of any power of attorney, if
      applicable.

     

    With
      respect to a maximum of approximately 5.00% of the original Mortgage Loans,
      by
      outstanding principal balance of the original Mortgage Loans as of the Cut-off
      Date, if any original Mortgage Note referred to in Section 4(b)(i) above cannot
      be located, the obligations of the Seller to deliver such documents shall be
      deemed to be satisfied upon delivery to the Trust Administrator (as designee
      of
      the Purchaser) of a photocopy of such Mortgage Note, if available, with a lost
      note affidavit. If any of the original Mortgage Notes for which a lost note
      affidavit was delivered to the Trust Administrator is subsequently located,
      such
      original Mortgage Note shall be delivered to the Trust Administrator within
      three Business Days.

     

    If
      any of
      the documents referred to in Sections 4(b)(ii), (iii) or (iv) above has as

      the Closing Date been submitted for recording but either (x) has not been
      returned from the applicable public recording office or (y) has been lost or
      such public recording office has retained the original of such document, the
      obligations of the Seller to deliver such documents shall be deemed to be
      satisfied upon (1) delivery to the Trust Administrator of a copy of each such
      document certified by the Originator in the case of (x) above or the applicable
      public recording office in the case of (y) above to be a true and complete
      copy
      of the original that was submitted for recording and (2) if such copy is
      certified by the Originator, delivery to the Trust Administrator promptly upon
      receipt thereof of either the original or a copy of such document certified
      by
      the applicable public recording office to be a true and complete copy of the
      original.

     

    To
      the
      extent not already recorded, the Trust Administrator, at the expense of the
      Seller shall pursuant to the Pooling and Servicing Agreement promptly (and
      in no
      event later than three months following the later of the Closing Date and the
      date of receipt by the Trust Administrator of the recording information for
      a
      Mortgage) submit or cause to be submitted for recording, at no expense to the
      Trust Estate or the Trust Administrator, in the appropriate public office for
      real property records, each Assignment delivered to it pursuant to Sections
      4(b)(iii) and (iv) above. In the event that any such Assignment is lost or
      returned unrecorded because of a defect therein, the Trust Administrator, at
      the
      expense of the Seller, shall promptly prepare or cause to be prepared a
      substitute Assignment or cure or cause to be cured such defect, as the case
      may
      be, and thereafter cause each such Assignment to be duly
      recorded.  Notwithstanding the foregoing, but without limiting the
      requirement that such Assignments be in recordable form, neither the Trust
      Administrator nor the Trustee shall be required to submit or cause to be
      submitted for recording each Assignment delivered to it pursuant to Sections
      4(b)(iii) and (iv) if such recordation shall not, as of the Closing Date, be
      required by the Rating Agencies, as a condition to their assignment on the
      Closing Date of their initial ratings to the Certificates, as evidenced by
      the
      delivery by the Rating Agencies of their ratings letters on the Closing
      Date.

     

    The
      Seller shall deliver or cause to be delivered to the Trust Administrator
      promptly upon receipt thereof any other original documents constituting a part
      of a Mortgage File received with respect to any Mortgage Loan, including, but
      not limited to, any original documents evidencing an assumption, modification,
      consolidation or extension of any Mortgage Loan.

     

    All
      original documents relating to the Mortgage Loans that are not delivered to
      the
      Trust Administrator are and shall be held by or on behalf of the Seller, the
      Servicer, the Purchaser or the Master Servicer, as the case may be, in trust
      for
      the benefit of the Trustee on behalf of the Certificateholders.  In
      the event that any such original document is required pursuant to the terms
      of
      this Section to be a part of a Mortgage File, such document shall be delivered
      promptly to the Trust Administrator. Any such original document delivered to
      or
      held by the Seller or the Purchaser that is not required pursuant to the terms
      of this Section to be a part of a Mortgage File, shall be delivered promptly
      to
      the related Servicer.

     

    (c)  Acceptance
      of Mortgage Loans. The documents delivered pursuant to Section 4(b) hereof
      shall be reviewed by the Purchaser or any assignee, transferee or designee
      of
      the Purchaser at any time before or after the Closing Date (and with respect
      to
      each document permitted to be delivered after the Closing Date within seven
      days
      of its delivery) to ascertain that all required documents have been executed
      and
      received and that such documents relate to the Mortgage Loans identified on
      the
      Mortgage Loan Schedule.

     

    (d)  Transfer
      of Interest in Agreements. The Purchaser has the right to assign its
      interest under this Agreement, in whole or in part, to the Trustee, as may
      be
      required to effect the purposes of the Pooling and Servicing Agreement, without
      the consent of the Seller, and the assignee shall succeed to the rights and
      obligations hereunder of the Purchaser. Any expense reasonably incurred by
      or on
      behalf of the Purchaser or the Trustee in connection with enforcing any
      obligations of the Seller under this Agreement will be promptly reimbursed
      by
      the Seller.

     

    (e)  Examination
      of Mortgage Files. Prior to the Closing Date, the Seller shall either (i)
      deliver in escrow to the Purchaser or to any assignee, transferee or designee
      of
      the Purchaser, for examination, the Mortgage File pertaining to each Mortgage
      Loan, or (ii) make such Mortgage Files available to the Purchaser or to any
      assignee, transferee or designee of the Purchaser for examination. Such
      examination may be made by the Purchaser or the Trustee, and their respective
      designees, upon reasonable notice to the Seller during normal business hours
      before the Closing Date and within 60 days after the Closing Date. If any such
      person makes such examination prior to the Closing Date and identifies any
      Mortgage Loans that do not conform to the requirements of the Purchaser as
      described in this Agreement, such Mortgage Loans shall be deleted from the
      Closing Schedule. The Purchaser may, at its option and without notice to the
      Seller, purchase all or part of the Mortgage Loans without conducting any
      partial or complete examination. The fact that the Purchaser or any person
      has
      conducted or has failed to conduct any partial or complete examination of the
      Mortgage Files shall not affect the rights of the Purchaser or any assignee,
      transferee or designee of the Purchaser to demand repurchase or other relief
      as
      provided herein or under the Pooling and Servicing Agreement.

      Seller hereby represents and warrants to the Purchaser, as of the date hereof

      under the laws of the State of New York with full corporate power and authority

      may
      be limited by bankruptcy, insolvency or reorganization or by general principles
      of equity.

     

    (iii)              The
      execution, delivery and performance of this Agreement by the Seller (x) does
      not
      conflict and will not conflict with, does not breach and will not result in
      a
      breach of and does not constitute and will not constitute a default (or an
      event, which with notice or lapse of time or both, would constitute a default)
      under (A) any terms or provisions of the articles of incorporation or by-laws
      of
      the Seller, (B) any term or provision of any material agreement, contract,
      instrument or indenture, to which the Seller is a party or by which the Seller

      judgment, writ, injunction or decree of any court or governmental authority
      having jurisdiction over the Seller or any of its property and (y) does not
      create or impose and will not result in the creation or imposition of any lien,
      charge or encumbrance which would have a material adverse effect upon the
      Mortgage Loans or any documents or instruments evidencing or securing the
      Mortgage Loans.

     

    (iv)              No
      consent, approval, authorization or order of, registration or filing with,
      or
      notice on behalf of the Seller to any governmental authority or court is
      required, under federal laws or the laws of the State of New York, for the
      execution, delivery and performance by the Seller of, or compliance by the
      Seller with, this Agreement or the consummation by the Seller of any other
      transaction contemplated hereby and by the Pooling and Servicing Agreement;
      provided, however, that the Seller makes no representation or warranty regarding
      federal or state securities laws in connection with the sale or distribution
      of
      the Certificates.

     

    (v)              This
      Agreement does not contain any untrue statement of material fact or omit to
      state a material fact necessary to make the statements contained herein not
      misleading.  The written statements, reports and other documents
      prepared and furnished or to be prepared and furnished by the Seller pursuant

      misleading.

      Seller is not in violation of, and the execution and delivery of this Agreement
      by the Seller and its performance and compliance with the terms of this
      Agreement will not constitute a violation with respect to, any order or decree
      of any court or any order or regulation of any federal, state, municipal or
      governmental agency having jurisdiction over the Seller or its assets, which
      violation might have consequences that would materially and adversely affect
      the
      condition (financial or otherwise) or the operation of the Seller or its assets
      or might have consequences that would materially and adversely affect the
      performance of its obligations and duties hereunder.

     

    (vii)              The
      Seller does not believe, nor does it have any reason or cause to believe, that
      it cannot perform each and every covenant contained in this
      Agreement.

     

    (viii)              Immediately
      prior to the sale of the Mortgage Loans to the Purchaser as herein contemplated,

      title, the Seller shall retain such record title to each Mortgage, each related
      Mortgage Note and the related Mortgage Files with respect thereto in trust
      for
      the Purchaser as the owner thereof from and after the date hereof.

     

    (ix)              There
      are no actions or proceedings against, or investigations known to it of, the
      Seller before any court, administrative or other tribunal (A) that might
      prohibit its entering into this Agreement, (B) seeking to prevent the sale
      of
      the Mortgage Loans by the Seller or the consummation of the transactions
      contemplated by this Agreement or (C) that might prohibit or materially and
      adversely affect the performance by the Seller of its obligations under, or
      validity or enforceability of, this Agreement.

     

    (x)              The

      to the bulk transfer or any similar statutory provisions.

     

    (xi)              The
      Seller has not dealt with any broker, investment banker, agent or other person,

      commission or compensation in connection with the sale of the Mortgage
      Loans.

     

    (xii)              There
      is no litigation currently pending or, to the best of the Seller’s knowledge
      without independent investigation, threatened against the Seller that would
      reasonably be expected to adversely affect the transfer of the Mortgage Loans,
      the issuance of the Certificates or the execution, delivery, performance or
      enforceability of this Agreement, or that would result in a material adverse
      change in the financial condition of the Seller.

              Section
                6.  

            	
              Repurchase
                Obligation for Defective Documentation and for Breach of Representation
                and Warranty.

            


    

     

    It
      is
      understood and agreed that the representations and warranties set forth in
      Section 5 shall survive the sale of the Mortgage Loans to the Purchaser and
      shall inure to the benefit of the Purchaser and any assignee, transferee or
      designee of the Purchaser, including the Trustee for the benefit of holders
      of
      the Mortgage Pass-Through Certificates evidencing an interest in all or a
      portion of the Mortgage Loans, notwithstanding any restrictive or qualified
      endorsement on any Mortgage Note or Assignment or the examination or lack of
      examination of any Mortgage File.  With respect to the representations
      and warranties contained herein that are made to the knowledge or the best
      knowledge of the Seller, or as to which the Seller has no knowledge, if it
      is
      discovered that the substance of any such representation and warranty is
      inaccurate and the inaccuracy materially and adversely affects the value of
      the
      related Mortgage Loan, or the interest therein of the Purchaser or the
      Purchaser’s assignee, designee or transferee, then notwithstanding the Seller’s
      lack of knowledge with respect to the substance of such representation and
      warranty being inaccurate at the time the representation and warranty was made,
      such inaccuracy shall be deemed a breach of the applicable representation and
      warranty and the Seller shall take such action described in the following
      paragraphs of this Section 6 in respect of such Mortgage Loan.  Upon
      discovery by either the Seller or the Purchaser of a breach of any of the
      foregoing representations and warranties made by the Seller that materially
      and
      adversely affects the value of the Mortgage Loans or the interest of the
      Purchaser (or which materially and adversely affects the interests of the
      Purchaser in the related Mortgage Loan in the case of a representation and
      warranty relating to a particular Mortgage Loan), the party discovering such
      breach shall give prompt written notice to the other.

     

    Within
      90
      days of the earlier of either discovery by or notice to the Seller of any breach
      of a representation or warranty made by the Seller that materially and adversely
      affects the value of a Mortgage Loan or the Mortgage Loans or the interest
      therein of the Purchaser, the Seller shall use its best efforts promptly to
      cure
      such breach in all material respects and, if such breach cannot be cured, the
      Seller shall, at the Purchaser’s option, repurchase such Mortgage Loan at the
      Purchase Price. The Seller may, at the request of the Purchaser and assuming
      the
      Seller has a Qualified Substitute Mortgage Loan, rather than repurchase a
      deficient Mortgage Loan as provided above, remove such Mortgage Loan and
      substitute in its place a Qualified Substitute Mortgage Loan or Loans. If the
      Seller does not provide a Qualified Substitute Mortgage Loan or Loans, it shall
      repurchase the deficient Mortgage Loan. Any repurchase of a Mortgage Loan(s)
      pursuant to the foregoing provisions of this Section 6 shall occur on a date
      designated by the Purchaser and shall be accomplished by deposit in accordance
      with Section 2.03 of the Pooling and Servicing Agreement. Any repurchase or
      substitution required by this Section shall be made in a manner consistent
      with
      Section 2.03 of the Pooling and Servicing Agreement.

     

    At
      the
      time of substitution or repurchase by the Seller of any deficient Mortgage
      Loan,
      the Purchaser and the Seller shall arrange for the reassignment of the
      repurchased or substituted Mortgage Loan to the Seller and the delivery to
      the
      Seller of any documents held by the Trustee relating to the deficient or
      repurchased Mortgage Loan. In the event the Purchase Price is deposited in
      the
      Collection Account. The Seller shall, simultaneously with such deposit, give
      written notice to the Purchaser that such deposit has taken place. Upon such
      repurchase, the Mortgage Loan Schedule shall be amended to reflect the
      withdrawal of the repurchased Mortgage Loan from this Agreement.

     

    As
      to any
      Deleted Mortgage Loan for which the Seller substitutes a Qualified Substitute
      Mortgage Loan or Loans, the Seller shall effect such substitution by delivering
      to the Purchaser or its designee for such Qualified Substitute Mortgage Loan
      or
      Loans the Mortgage Note, the Mortgage, the Assignment and such other documents
      and agreements as are required by the Pooling and Servicing Agreement, with
      the
      Mortgage Note endorsed as required therein. The Seller shall remit for deposit
      in the Collection Account the Monthly Payment due on such Qualified Substitute
      Mortgage Loan or Loans in the month following the date of such substitution.
      Monthly payments due with respect to Qualified Substitute Mortgage Loans in
      the
      month of substitution will be retained by the Seller. For the month of
      substitution, distributions to the Purchaser will include the Monthly Payment
      due on such Deleted Mortgage Loan in the month of substitution, and the Seller
      shall thereafter be entitled to retain all amounts subsequently received by
      the
      Seller in respect of such Deleted Mortgage Loan. Upon such substitution, the
      Qualified Substitute Mortgage Loans shall be subject to the terms of this
      Agreement in all respects, and the Seller shall be deemed to have made with
      respect to such Qualified Substitute Mortgage Loan or Loans as of the date
      of
      substitution, the covenants, representations and warranties set forth in Section
      5.

     

    It
      is
      understood and agreed that the representations and warranties set forth in
      Section 5 shall survive delivery of the respective Mortgage Files to the Trustee
      on behalf of the Purchaser.

     

    It
      is
      understood and agreed that (i) the obligations of the Seller set forth in this
      Section 6 to cure, repurchase and substitute for a defective Mortgage Loan
      and
      (ii) the obligations of the Seller as provided in the next sentence constitute
      the sole remedies of the Purchaser respecting a missing or defective document
      or
      a breach of the representations and warranties contained in Section
      5.   The Seller shall indemnify the Purchaser and hold it
      harmless against any losses, damages, penalties, fines, forfeitures, reasonable
      and necessary legal fees and related costs, judgments, and other costs and
      expenses resulting from any claim, demand, defense or assertion based on or
      grounded upon, or resulting from, a breach of the representations and warranties
      contained in Sections 5(a), (c), (d) and (e) this Agreement.

     

    Section
      7.  Closing;
      Payment for the Mortgage Loans. The closing of the purchase and sale of the
      Mortgage Loans shall be held at the New York City office of Thacher Proffitt
      & Wood llp at 10:00 AM New York City time on the Closing Date.

     

    The
      closing shall be subject to each of the following conditions:

     

    (a)  All
      of
      the representations and warranties of the Seller under this Agreement shall

      true and correct in all material respects as of the date as of which they are
      made and no event shall have occurred which, with notice or the passage of
      time,
      would constitute a default under this Agreement;

     

    (b)  The
      Purchaser shall have received, or the attorneys of the Purchaser shall have
      received in escrow (to be released from escrow at the time of closing), all
      Closing Documents as specified in Section 8 of this Agreement, in such forms
      as
      are agreed upon and acceptable to the Purchaser, duly executed by all
      signatories other than the Purchaser as required pursuant to the respective
      terms thereof;

     

    (c)  The
      Seller shall have delivered or caused to be delivered and released to the
      Purchaser or to its designee, all documents (including without limitation,
      the
      Mortgage Loans) required to be so delivered by the Purchaser; and

     

    (d)  All
      other
      terms and conditions of this Agreement shall have been complied
      with.

     

    Subject
      to the foregoing conditions, the Purchaser shall deliver or cause to be
      delivered to the Seller on the Closing Date, against delivery and release by

      shall be subject to delivery of each of the following documents:

      Supplement, dated February 27, 2007 and the Purchaser’s Private Placement
      Memorandum, dated February 28, 2007, agrees with the records of the
      Seller;

     

    (h)  Letters
      from certified public accountants for each Originator, dated the date hereof
      and
      to the effect that they have performed certain specified procedures as a result
      of which they determined that certain information of an accounting, financial
      or
      statistical nature set forth in the Purchaser’s Prospectus Supplement, dated
      February 27, 2007 under the subheading “The Servicer” and the Purchaser’s
      Private Placement Memorandum, dated February 28, 2006, under the subheading
“The
      Servicer” agrees with the records of the Servicer; and

     

    (i)  Such
      further information, certificates, opinions and documents as the Purchaser
      or
      the Underwriter may reasonably request.

     

    Section
      9.  Costs.
      The Seller shall pay (or shall reimburse the Purchaser or any other Person
      to
      the extent that the Purchaser or such other Person shall pay) all necessary
      and
      reasonable costs and expenses incurred directly in delivering this Agreement,
      the Pooling and Servicing Agreement, the Certificates, the prospectus,
      prospectus supplement and private placement memorandum relating to the
      Certificates and other related documents, the initial fees, costs and expenses
      of the Trust Administrator and the Trustee set forth in an engagement letter
      delivered to the Seller by the Trust Administrator, the fees and expenses of
      the
      Purchaser’s counsel in connection with the preparation of all documents relating
      to the securitization of the Mortgage Loans, the filing fee charged by the
      Securities and Exchange Commission for registration of the Certificates, the
      fees charged by any rating agency to rate the Certificates and the ongoing
      expenses of the Rating Agencies. All other costs and expenses in connection
      with
      the transactions contemplated hereunder shall be borne by the party incurring
      such expense.

     

    Section
      10.  [Reserved].

     

    Section
      11.  Mandatory
      Delivery; Grant of Security Interest. The sale and delivery on the Closing
      Date of the Mortgage Loans described on the Mortgage Loan Schedule in accordance
      with the terms and conditions of this Agreement is mandatory. It is specifically
      understood and agreed that each Mortgage Loan is unique and identifiable on
      the
      date hereof and that an award of money damages would be insufficient to
      compensate the Purchaser for the losses and damages incurred by the Purchaser
      in
      the event of the Seller’s failure to deliver the Mortgage Loans on or before the
      Closing Date. The Seller hereby grants to the Purchaser a lien on and a
      continuing security interest in the Seller’s interest in each Mortgage Loan and
      each document and instrument evidencing each such Mortgage Loan to secure the
      performance by the Seller of its obligation hereunder, and the Seller agrees
      that it holds such Mortgage Loans in custody for the Purchaser, subject to
      the
      Purchaser’s (i) right, prior to the Closing Date, to reject any Mortgage Loan to
      the extent permitted by this Agreement and (ii) obligation to deliver or cause
      to be delivered the consideration for the Mortgage Loans pursuant to Section
      7
      hereof. Any Mortgage Loans rejected by the Purchaser shall concurrently
      therewith be released from the security interest created hereby. The Seller
      agrees that, upon acceptance of the Mortgage Loans by the Purchaser or its
      designee and delivery of payment to the Seller, that its security interest
      in
      the Mortgage Loans shall be released. All rights and remedies of the Purchaser
      under this Agreement are distinct from, and cumulative with, any other rights
      or
      remedies under this Agreement or afforded by law or equity and all such rights
      and remedies may be exercised concurrently, independently or
      successively.

     

    Notwithstanding
      the foregoing, if on the Closing Date, each of the conditions set forth in
      Section 7 hereof shall have been satisfied and the Purchaser shall not have
      paid
      or caused to be paid the Mortgage Loan Purchase Price, or any such condition
      shall not have been waived or satisfied and the Purchaser determines not to
      pay
      or cause to be paid the Mortgage Loan Purchase Price, the Purchaser shall
      immediately effect the redelivery of the Mortgage Loans, if delivery to the
      Purchaser has occurred and the security interest created by this Section 11
      shall be deemed to have been released.

     

    Section
      12.  Notices.
      All demands, notices and communications hereunder shall be in writing and shall
      be deemed to have been duly given if personally delivered to or mailed by
      registered mail, postage prepaid, or transmitted by telex or telegraph and
      confirmed by a similar mailed writing, if to the Purchaser, addressed to the
      Purchaser at 390 Greenwich Street, 4th Floor, New York, New York 10013,
      Attention: Mortgage Finance Group, or such other address as may hereafter be
      furnished to the Seller in writing by the Purchaser, and if to the Seller,
      addressed to the Seller at 388 Greenwich Street, 4th Floor, New York, New York
      10013, Attention: Mortgage Finance Group, or such other address as may hereafter
      be furnished to the Purchaser in writing by the Seller.

     

    Section
      13.  Severability
      of Provisions. Any part, provision, representation or warranty of this
      Agreement which is prohibited or which is held to be void or unenforceable
      shall
      be ineffective to the extent of such prohibition or unenforceability without
      invalidating the remaining provisions hereof. Any part, provision,
      representation or warranty of this Agreement which is prohibited or
      unenforceable or is held to be void or unenforceable in any jurisdiction shall,
      as to such jurisdiction, be ineffective to the extent of such prohibition or
      unenforceability without invalidating the remaining provisions hereof, and
      any
      such prohibition or unenforceability in any jurisdiction as to any Mortgage
      Loan
      shall not invalidate or render unenforceable such provision in any other
      jurisdiction. To the extent permitted by applicable law, the parties hereto
      waive any provision of law which prohibits or renders void or unenforceable
      any
      provision hereof.

     

    Section
      14.  Agreement
      of Parties. The Seller and the Purchaser each agree to execute and deliver
      such instruments and take such actions as either of the others may, from time
      to
      time, reasonably request in order to effectuate the purpose and to carry out
      the
      terms of this Agreement and the Pooling and Servicing Agreement.

     

    Section
      15.  Survival.
      The Seller agrees that the representations, warranties and agreements made
      by it
      herein and in any certificate or other instrument delivered pursuant hereto
      shall be deemed to be relied upon by the Purchaser, notwithstanding any
      investigation heretofore or hereafter made by the Purchaser or on its behalf,
      and that the representations, warranties and agreements made by the Seller
      herein or in any such certificate or other instrument shall survive the delivery
      of and payment for the Mortgage Loans and shall continue in full force and
      effect, notwithstanding any restrictive or qualified endorsement on the Mortgage
      Notes and notwithstanding subsequent termination of this Agreement, the Pooling
      and Servicing Agreement or the Trust Fund.

     

    Section
      16.  GOVERNING
      LAW. THIS AGREEMENT AND THE RIGHTS, DUTIES, OBLIGATIONS AND RESPONSIBILITIES
      OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
      THE
      LAWS (INCLUDING THE CHOICE OF LAW PROVISIONS) AND DECISIONS OF THE STATE OF
      NEW
      YORK. THE PARTIES HERETO INTEND THAT THE PROVISIONS OF SECTION 5-1401 OF THE
      NEW
      YORK GENERAL OBLIGATIONS LAW SHALL APPLY TO THIS AGREEMENT.

     

    Section
      17.  Miscellaneous.
      This Agreement may be executed in two or more counterparts, each of which when
      so executed and delivered shall be an original, but all of which together shall
      constitute one and the same instrument. This Agreement shall inure to the
      benefit of and be binding upon the parties hereto and their respective
      successors and assigns. This Agreement supersedes all prior agreements and
      understandings relating to the subject matter hereof. Neither this Agreement
      nor
      any term hereof may be changed, waived, discharged or terminated orally, but
      only by an instrument in writing signed by the party against whom enforcement
      of
      the change, waiver, discharge or termination is sought. The headings in this
      Agreement are for purposes of reference only and shall not limit or otherwise
      affect the meaning hereof.

     

    It
      is the
      express intent of the parties hereto that the conveyance of the Mortgage Loans
      by the Seller to the Purchaser as provided in Section 4 hereof be, and be
      construed as, a sale of the Mortgage Loans by the Seller to the Purchaser and
      not as a pledge of the Mortgage Loans by the Seller to the Purchaser to secure
      a
      debt or other obligation of the Seller. However, in the event that,
      notwithstanding the aforementioned intent of the parties, the Mortgage Loans
      are
      held to be property of the Seller, then, (a) it is the express intent of the
      parties that such conveyance be deemed a pledge of the Mortgage Loans by the
      Seller to the Purchaser to secure a debt or other obligation of the Seller
      and
      (b) (1) this Agreement shall also be deemed to be a security agreement within
      the meaning of Articles 8 and 9 of the New York Uniform Commercial Code; (2)
      the
      conveyance provided for in Section 4 hereof shall be deemed to be a grant by
      the
      Seller to the Purchaser of a security interest in all of the Seller’s right,
      title and interest in and to the Mortgage Loans and all amounts payable to
      the
      holders of the Mortgage Loans in accordance with the terms thereof and all
      proceeds of the conversion, voluntary or involuntary, of the foregoing into
      cash, instruments, securities or other property, including without limitation
      all amounts, other than investment earnings, from time to time held or invested
      in the Collection Account whether in the form of cash, instruments, securities
      or other property; (3) the possession by the Purchaser or its agent of Mortgage
      Notes, the related Mortgages and such other items of property that constitute
      instruments, money, negotiable documents or chattel paper shall be deemed to
      be
“possession by the secured party” for purposes of perfecting the security
      interest pursuant to Section 9-305 of the New York Uniform Commercial Code;
      and
      (4) notifications to persons holding such property, and acknowledgments,
      receipts or confirmations from persons holding such property, shall be deemed
      notifications to, or acknowledgments, receipts or confirmations from, financial
      intermediaries, bailees or agents (as applicable) of the Purchaser for the
      purpose of perfecting such security interest under applicable law. Any
      assignment of the interest of the Purchaser pursuant to Section 4(d) hereof
      shall also be deemed to be an assignment of any security interest created
      hereby. The Seller and the Purchaser shall, to the extent consistent with this
      Agreement, take such actions as may be necessary to ensure that, if this
      Agreement were deemed to create a security interest in the Mortgage Loans,
      such
      security interest would be deemed to be a perfected security interest of first
      priority under applicable law and will be maintained as such throughout the
      term
      of this Agreement and the Pooling and Servicing Agreement.

     

    Section
      18.  Indemnification.
      The Seller shall indemnify and hold harmless each of (i) the Purchaser, (ii)
      Citigroup Global Markets Inc. and (iii) each person, if any, who controls the
      Purchaser within the meaning of Section 15 of the Securities Act of 1933, as
      amended (the “1933 Act”) ((i) through (iii) collectively, the “Indemnified
      Party”) against any and all losses, claims, expenses, damages or liabilities to
      which the Indemnified Party may become subject, under the 1933 Act or otherwise,
      insofar as such losses, claims, expenses, damages or liabilities (or actions
      in
      respect thereof) arise out of, are based upon, or result from, a breach by
      the
      Seller of any of  the representations and warranties made by the
      Seller herein, it being understood that the Purchaser has relied upon such
      representations and warranties.

     

    IN
      WITNESS WHEREOF, the Purchaser and the Seller have caused their names to be
      signed by their respective officers thereunto duly authorized as of the date
      first above written.

    EXHIBIT
      A

    


    Representation
      and Warranties with Respect to the Countrywide Mortgage
      Loans

    


    Except
      for “Mortgage Loans”, which
      shall mean the Countrywide Mortgage Loans sold by the Seller to the Purchaser,
      all capitalized terms in this Exhibit A shall have the meanings ascribed to
      them
      in the Countrywide Purchase Agreement.

    


    (a)  Mortgage
      Loan Schedule.  The information contained in the Mortgage Loan
      Schedule is complete, true and correct in all material respects;

     

    (b)  No
      Delinquencies or Advances.  All payments required to be made prior
      to the related Cut-off Date for such Mortgage Loan under the terms of the
      Mortgage Note have been made; Countrywide has not advanced funds, or induced,
      solicited or knowingly received any advance of funds from a party other than
      the
      owner of the Mortgaged Property subject to the Mortgage, directly or indirectly,
      for the payment of any amount required by the Mortgage Loan; and there has
      been
      no delinquency of more than thirty (30) days in any payment by the Mortgagor
      thereunder during the last twelve (12) months;

     

    (c)  Taxes,
      Assessments, Insurance Premiums and Other Charges.  There are no
      delinquent taxes, ground rents, or insurance premiums, and Countrywide has
      no
      knowledge of any delinquent water charges, sewer rents, assessments, leasehold
      payments, including assessments payable in future installments or other
      outstanding charges affecting the related Mortgaged Property;

     

    (d)  No
      Modifications.  The terms of the Mortgage Note and the Mortgage
      have not been impaired, waived, altered or modified in any respect, except
      by
      written instruments that have been or will be recorded or registered with the
      MERS System, if necessary to protect the interests of the Purchaser, and that
      have been or will be delivered to the Purchaser, all in accordance with this
      Agreement.  The substance of any such waiver, alteration or
      modification has been approved by the primary mortgage guaranty insurer, if
      any,
      and by the title insurer, to the extent required by the related policy and
      its
      terms are reflected on the Mortgage Loan Schedule.  No Mortgagor has
      been released, in whole or in part, except in connection with an assumption
      agreement approved by the primary mortgage insurer, if any, and the title
      insurer, to the extent required by the policy, and which assumption agreement
      is
      part of the Collateral File and the terms of which are reflected in the Mortgage
      Loan Schedule if executed prior to the Closing Date;

     

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

     

    (f)  Hazard
      and Flood Insurance.  All buildings upon the Mortgaged Property
      are insured by an insurer acceptable to an Agency against loss by fire, hazards
      of extended coverage and such other hazards as are customary in the area where
      the Mortgaged Property is located, and such insurer is licensed to do business
      in the state where the Mortgaged Property is located.  All such
      insurance policies contain a standard mortgagee clause naming Countrywide,
      its
      successors and assigns as mortgagee, and all premiums thereon have been
      paid.  If, upon the origination of the Mortgage Loan, the Mortgaged
      Property was, or was subsequently deemed to be, 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 that meets the requirements of the current guidelines of the
      Federal Insurance Administration (or any successor thereto) and conforms to
      the
      requirements of an Agency is in effect.  The Mortgage obligates the
      Mortgagor thereunder to maintain all such insurance at the Mortgagor’s expense
      and, upon the failure of the Mortgagor to do so, the holder of the Mortgage
      is
      authorized to maintain such insurance at the Mortgagor’s expense and to seek
      reimbursement therefore from the Mortgagor;

     

    (g)  Compliance
      with Applicable Law.  Each Mortgage Loan, including any Prepayment
      Charge or penalty in connection therewith, at the time of origination complied
      in all material respects with applicable local, state and federal laws, and
      any
      applicable ordinances, including truth in lending, real estate settlement
      procedures, consumer credit protection, equal credit opportunity, predatory
      and
      abusive lending and disclosure laws applicable to the Mortgage
      Loan;

     

    (h)  No
      Release of Mortgage.  The Mortgage has not been satisfied,
      canceled, 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;

     

    (i)  Enforceability
      of Mortgage Documents.  The Mortgage Note and the related Mortgage
      are genuine and each is the legal, valid and binding obligation of the maker
      thereof, enforceable in accordance with its terms, except as the enforceability
      thereof may be limited by bankruptcy, insolvency, reorganization or similar
      laws;

     

    (j)  Valid
      First or Second Lien.  Each related Mortgage is a valid,
      subsisting and enforceable First Lien (with respect to a First Lien Mortgage
      Loan) or Second Lien (with respect to a Second Lien Mortgage Loan) on the
      related Mortgaged Property, including all improvements on the Mortgaged
      Property.  The lien of the Mortgage is subject only to:

     

     

    (i)  the
      lien
      of current real property taxes and assessments not yet due and
      payable;

     

    (ii)  covenants,
      conditions and restrictions, rights of way, easements and other matters of
      public record as of the date of recording that are acceptable to mortgage
      lending institutions generally and specifically referred to in the lender’s
      title insurance policy delivered to the originator of the Mortgage Loan and
      that
      do not adversely affect the Appraised Value (as evidenced by an appraisal
      referred to in such definition) of the Mortgaged Property set forth in such
      appraisal;

     

    (iii)  with
      respect to a Second Lien Mortgage Loan only, the lien of the first mortgage
      on
      the Mortgaged Property; and

     

    (iv)  other
      matters to which like properties are commonly subject which do not materially
      interfere with the benefits of the security intended to be provided by the
      Mortgage or the use, enjoyment, value or marketability of the related Mortgaged
      Property;

     

    (k)  Disbursements
      of Proceeds.  The proceeds of the 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 therefore have been complied
      with.  All costs, fees and expenses incurred in making or closing the
      Mortgage Loan and recording the Mortgage were paid, and the Mortgagor is not
      entitled to any refund of any amounts paid or due under the Mortgage Note or
      Mortgage;

     

    (l)  Sole
      Owner.  Countrywide is the sole owner and holder of the Mortgage
      Loan.  The Mortgage Loan is not assigned or pledged, and Countrywide
      has good and marketable title thereto, and has full right to transfer and sell
      the Mortgage Loan to the Purchaser free and clear of any encumbrance, equity,
      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 Mortgage Loan pursuant to the terms of
      this
      Agreement;

     

    (m)  Title
      Insurance.  Each Mortgage Loan that is a First Lien Mortgage Loan
      and each Mortgage Loan that is a Second Lien Mortgage Loan with an original
      principal balance greater than $100,000, in either case, is covered by a
      lender’s title insurance policy acceptable to an Agency, issued by a title
      insurer acceptable to an Agency and qualified to do business in the jurisdiction
      where the related Mortgaged Property is located, insuring (subject to the
      exceptions contained in Section 3.02(j)(i), (ii) and (iii) above) Countrywide,
      its successors and assigns as to the first or second priority lien of the
      Mortgage, as applicable.  Additionally, such lender’s title insurance
      policy affirmatively insures ingress and egress, and against encroachments
      by or
      upon the Mortgaged Property or any interest therein.  With respect to
      any Adjustable Rate Mortgage Loan, such title insurance policy insures against
      any loss by reason of the invalidity or unenforceability of the lien resulting
      from the provisions of the Mortgage Note providing for adjustment of the
      Mortgage Interest Rate and Monthly Payment.  Countrywide is the sole
      insured of such lender’s title insurance policy, and such lender’s title
      insurance policy is in full force and effect and will be in full force and
      effect upon the consummation of the transactions contemplated by this
      Agreement.  No claims have been made under such lender’s title
      insurance policy, and no prior holder of the related Mortgage, including
      Countrywide, has done, by act or omission, anything which would impair the
      coverage of such lender’s title insurance policy;

     

    (n)  No
      Default.  There is no default, breach, violation or event of
      acceleration existing under the Mortgage or the Mortgage Note and no event
      which, with the passage of time or with notice and the expiration of any grace
      or cure period, would constitute a default, breach, violation or event of
      acceleration, and Countrywide has not waived any default, breach, violation
      or
      event of acceleration, and with respect to any Second Lien Mortgage Loan,
      Countrywide has not received a written notice of default of any senior mortgage
      loan related to the Mortgaged Property which has not been cured;

     

    (o)  No
      Mechanics’ Liens.  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) affecting the related
      Mortgaged Property which are or may be liens prior to, or equal or coordinate
      with, the lien of the related Mortgage;

     

    (p)  Origination,
      Servicing and Collection Practices.  The origination, servicing
      and collection practices used by Countrywide with respect to each Mortgage
      Note
      and Mortgage have been in all respects legal, proper, prudent and customary
      in
      the mortgage origination and servicing business.  With respect to
      escrow deposits and Escrow Payments, if any, all such payments are in the
      possession of, or under the control of, Countrywide and there exist no
      deficiencies in connection therewith for which customary arrangements for
      repayment thereof have not been made.  No escrow deposits or Escrow
      Payments or other charges or payments due Countrywide have been capitalized
      under any Mortgage or the related Mortgage Note.  With respect to
      Adjustable Rate Mortgage Loans, all Mortgage Interest Rate adjustments have
      been
      made in strict compliance with state and federal law and the terms of the
      related Mortgage Note.  Any interest required to be paid pursuant to
      state and local law has been properly paid and credited;

     

    (q)  No
      Condemnation or Damage.  The Mortgaged Property is free of
      material damage and waste and there is no proceeding pending for the total
      or
      partial condemnation thereof;

     

    (r)  Customary
      and Enforceable Provisions.  The Mortgage contains customary and
      enforceable provisions such as to render the rights and remedies of the holder
      thereof adequate for the realization against the Mortgaged Property of the
      benefits of the security provided thereby including (a) in the case of a
      Mortgage designated as a deed of trust, by trustee’s sale, and (b) otherwise by
      judicial foreclosure;

     

    (s)  Collateral.  The
      Mortgage Note is not and has not been secured by any collateral except the
      lien
      of the corresponding Mortgage;

     

    (t)  Appraisal.  Unless
      the Mortgage Loan was underwritten pursuant to one of Countrywide’s streamline
      documentation programs, the Credit File contains an appraisal of the related
      Mortgaged Property signed prior to the approval of the Mortgage Loan application
      by an appraiser who meets the minimum requisite qualifications of an Agency
      for
      appraisers, duly appointed by the originator, that had no interest, direct
      or
      indirect in the Mortgaged Property, and whose compensation is not affected
      by
      the approval or disapproval of the Mortgage Loan; the appraisal is in a form
      acceptable to an Agency, with such riders as are acceptable to such
      Agency.  All improvements which were considered in determining the
      Appraised Value of the related Mortgaged Property lay wholly within the
      boundaries and building restriction lines of the Mortgaged Property, and no
      improvements on adjoining properties encroach upon the Mortgaged Property.
      Each
      appraisal of the Mortgage Loan was made in accordance with the relevant
      provisions of the Financial Institutions Reform, Recovery, and Enforcement
      Act
      of 1989;

     

    (u)  Trustee
      for Deed of Trust.  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 Purchaser to the
      trustee under the deed of trust, except in connection with a trustee’s sale
      after default by the Mortgagor;

     

    (v)  Private
      Mortgage Insurance, FHA Insurance and VA Guarantees.  Each
      Mortgage Loan, except a Second Lien Mortgage Loan or a Mortgage Loan
      underwritten in accordance with sub-prime credit underwriting guidelines (as
      any
      such Mortgage Loans may be identified in the Mortgage Loan Schedule), with
      an
      LTV at origination in excess of eighty percent (80%) is and will be subject
      to a
      PMI Policy, which insures that portion of the Mortgage Loan over seventy-five
      percent (75%) of the Appraised Value of the related Mortgaged
      Property.  All provisions of such PMI Policy have been and are being
      complied with, such policy is in full force and effect, and all premiums due
      thereunder have been paid.  Any Mortgage subject to any such PMI
      Policy obligates the Mortgagor thereunder to maintain such insurance and to
      pay
      all premiums and charges in connection therewith or, in the case of a lender
      paid mortgage insurance policy, the premiums and charges are included in the
      Mortgage Interest Rate for the Mortgage Loan.  Each Government
      Mortgage Loan either has, or will have in due course, a valid and enforceable
      MIC or LGC, as applicable and, in each case, all premiums due thereunder have
      been paid;

     

    (w)  Lawfully
      Occupied.  At origination, to the best of Countrywide’s knowledge
      as of the Closing Date, 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
      certificates of occupancy, have been made or obtained from the appropriate
      authorities;

     

    (x)  Assignment
      of Mortgage.  Except for the absence of recording information, 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.  The original Mortgage was or is being recorded and, unless
      the Mortgage Loan is subject to the MERS System, all subsequent assignments
      of
      the original Mortgage (other than the assignment to Purchaser) have been
      recorded in the appropriate jurisdiction wherein such recordation is necessary
      to perfect the lien thereof against creditors of Countrywide, or is in the
      process of being recorded;

     

    (y)  Consolidation
      of Future Advances.  Any future advances made to the Mortgagor
      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
      consolidated principal amount does not exceed the original principal amount
      of
      the Mortgage Loan;

     

    (z)  Form
      of Mortgage Note and Mortgage.  The Mortgage Note and Mortgage are
      on forms acceptable to an Agency;

     

    (aa)  Section
      32 Loans.  No Mortgage Loan is (a) subject to the provisions of
      the Homeownership and Equity Protection Act of 1994 as amended (“HOEPA”), (b) a
“high cost” mortgage loan, “high risk” mortgage loan; “covered” mortgage loan or
“predatory” mortgage loan or a similarly classified mortgage 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, no matter how defined, under any federal, state
      or
      local law or ordinance, including, without limitation, Section 6-L of the New
      York Banking Law or (c) subject to any comparable federal, state or local
      statutes or regulations, including, without limitation, the provisions of the
      Georgia Fair Lending Act or any other statute or regulation providing assignee
      liability to holders of such mortgage loans;

     

    (bb)  Originator
      Supervision.  The Mortgage Loan was originated by Countrywide or
      by a savings bank, a commercial bank or similar banking institution which is
      supervised and examined by a federal or state authority, or by a mortgagee
      approved as such by the Secretary of HUD;

     

    (cc)  Foreclosure;
      Bankruptcy.  The Mortgaged Property has not been subject to any
      bankruptcy proceeding or foreclosure proceeding and the Mortgagor has not filed
      for protection under applicable bankruptcy laws.  There is no
      homestead or other exemption available to the Mortgagor which would interfere
      with the right to sell the Mortgaged Property at a trustee’s sale or the right
      to foreclose the Mortgage.  Countrywide has no knowledge of any relief
      requested or allowed to the Mortgagor under the Soldiers and Sailors Civil
      Relief Act of 1940;

     

    (dd)  Payment
      Source; Buydown.  No Mortgage contains provisions pursuant to
      which Monthly Payments are (a) paid or partially paid with funds deposited
      in
      any separate account established by the Seller, the Mortgagor, or anyone on
      behalf of the Mortgagor, (b) paid by any source other than the Mortgagor or
      (c)
      contains any other similar provisions which may constitute a “buydown”
provision.  The Mortgage Loan is not a graduated payment mortgage loan
      and the Mortgage Loan does not have a shared appreciation or other contingent
      interest feature;

     

    (ee)  Construction;
      Exchange.  No Mortgage Loan was made solely in connection with (a)
      the construction or rehabilitation of a Mortgaged Property or (b) facilitating
      the trade-in or exchange of a Mortgaged Property.

     

    (ff)  Investment.  Countrywide
      has no knowledge of any circumstances or condition 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, cause the Mortgage Loan to become delinquent, or materially and
      adversely affect the value of the Mortgage Loan.

     

    (gg)  Accrual
      Method.  Interest on each Mortgage Loan is calculated on the basis
      of a 360-day year consisting of twelve 30-day months; and

     

    (hh)  Lending
      Practices.  No predatory, abusive or deceptive lending practices,
      including, but not limited to, the extension of credit to the Mortgagor without
      regard for the Mortgagor’s ability to repay the Mortgage Loan and the extension
      of credit to the Mortgagor which has no apparent benefit to the Mortgagor,
      were
      employed by the originator of the Mortgage Loan in connection with the
      origination of the Mortgage Loan;

     

    (ii)  Prepayment
      Charges.  Each Prepayment Charge or penalty with respect to any
      Mortgage Loan is permissible, enforceable and collectible under applicable
      federal, state and local law;

     

    (jj)  No
      Adverse Selection.  The Mortgage Loans were not selected from the
      outstanding one to four-family mortgage loans in Countrywide’s portfolio at the
      related Closing Date as to which the representations and warranties set forth
      in
      this Agreement could be made in a manner so as to affect adversely the interests
      of the Purchaser;

     

    (kk)  Due
      on
      Sale.  The Mortgage contains an enforceable provision 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;

     

    (ll)  Legal
      Capacity.  To the best of Countrywide’s knowledge, all parties to
      the Mortgage Note and the Mortgage had legal capacity to enter into the Mortgage
      Loan and to execute and deliver the Mortgage Note and the Mortgage, and the
      Mortgage Note and the Mortgage have been duly and properly executed by such
      parties.  The Mortgagor is a natural person;

     

    (mm)  Doing
      Business.  Countrywide is, and to the best of Countrywide’s
      knowledge, all parties which have had any interest in the Mortgage Loan, whether
      as mortgagee, assignee, hereof or otherwise, are (or, during the period in
      which
      they held and disposed of such interest, were) in compliance with any and all
      applicable “doing business” and licensing requirements of the laws of the state
      wherein the Mortgaged Property is located;

     

    (nn)  Interest
      Rates; Amortization.  Except for a Mortgage Loan, the Monthly
      Payment of which consists of interest only for a specified period of time (and
      which Mortgage Loan is identified on the Mortgage Loan Schedule), principal
      payments on the Mortgage Loan commenced no more than sixty days after the
      proceeds of the Mortgage Loan were disbursed.  The Mortgage Loan bears
      interest at the Mortgage Interest Rate.  With respect to each Mortgage
      Loan other than an interest-only Mortgage Loan or Balloon Mortgage Loan, the
      Mortgage Note is payable on the first day of each month in Monthly Payments,
      which, in the case of a Fixed Rate Mortgage Loan, is sufficient to fully
      amortize the original principal balance over the original term thereof and
      to
      pay interest at the related Mortgage Interest Rate, and, in the case of an
      Adjustable Rate Mortgage Loan, is changed on each Adjustment Date and is
      sufficient to fully amortize the original principal balance over the original
      term thereof and to pay interest at the related Mortgage Interest Rate. With
      respect to each Mortgage Loan identified on the Mortgage Loan Schedule as an
      interest-only Mortgage Loan, the interest-only period shall not exceed the
      period specified on the Mortgage Loan Schedule and, following the expiration
      of
      such interest-only period, the remaining Monthly Payments shall be sufficient to
      fully amortize the original principal balance over the remaining term of the
      Mortgage Loan.  With respect to each Balloon Mortgage Loan, the
      Mortgage Note requires Monthly Payments sufficient to fully amortize the
      original principal balance over the original term thereof and to pay interest
      at
      the related Mortgage Interest Rate but requires a final Monthly Payment which
      is
      substantially greater than the penultimate Monthly Payment and sufficient to
      repay the remaining unpaid principal balance of the Balloon Mortgage Loan on
      the
      Due Date of such final Monthly Payment;

     

    (oo)  Underwriting
      Standards.  The Mortgage Loan was underwritten in accordance with
      the underwriting standards of Countrywide in effect at the time the Mortgage
      Loan was originated;

     

    (pp)  Disclosures.  The
      Mortgagor has received all disclosure materials required by applicable law
      with
      respect to the making of fixed rate mortgage loans in the case of Fixed Rate
      Mortgage Loans, and adjustable rate mortgage loans in the case of Adjustable
      Rate Mortgage Loans and rescission materials with respect to Refinanced Mortgage
      Loans, and such statement is and will remain in the Mortgage File;

     

    (qq)  No
      Fraud.  No error, omission, misrepresentation, fraud or similar
      occurrence with respect to a Mortgage Loan has taken place on the part of
      Countrywide or, to the best of Countrywide’s knowledge, 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;

     

    (rr)  Condominiums;
      Planned Unit Developments.  If the Residential Dwelling on the
      Mortgaged Property is a condominium unit or a unit in a planned unit development
      (other than a de minimis planned unit development) such condominium or planned
      unit development project meets the eligibility requirements of FNMA and
      FHLMC;

     

    (ss)  No
      Credit Life.  No Mortgagor was required to purchase any credit
      life, disability, accident or health insurance product as a condition of
      obtaining the extension of credit.  No proceeds from any Mortgage Loan
      were used to purchase single premium credit insurance policies as a condition
      to
      closing such Mortgage Loan;

     

    (tt)  Disclosure
      of Fees and Charges.  All fees and charges (including finance
      charges), whether or not financed, assessed, collected or to be collected in
      connection with the origination and servicing of a Mortgage Loan, have been
      disclosed in writing to the Mortgagor in accordance with applicable state and
      federal law and regulation;

     

    (uu)  Compliance
      with Consumer Credit Statutes.  The Mortgage Loan complies with
      all applicable consumer credit statutes and regulations, including, without
      limitation, the respective Uniform Consumer Credit Code laws in effect in
      Colorado, Idaho, Indiana, Iowa, Kansas, Maine, Oklahoma, South Carolina, Utah
      and Wyoming, has been originated by a properly licensed entity, and in all
      other
      respects, complies with all of the material requirements of any such applicable
      laws;

     

    (vv)  No
      Coops, Commercial Property or Mobile Homes.  No Mortgage Loan is
      secured by cooperative housing, commercial property or mixed use property,
      and
      no Mortgage Loan is a manufactured or mobile home;

     

    (ww)  Fair
      Credit Reporting.  Countrywide has fully furnished and will
      continue to furnish, in accordance with the Fair Credit Reporting Act and its
      implementing regulations (the “FCRA”), accurate and complete information (i.e.,
      favorable and unfavorable) on its Mortgagor credit files to Equifax, Experian,
      and Trans Union Credit Information Company (three of the credit repositories),
      on a monthly basis, and will fully furnish, in accordance with the FCRA,
      accurate and complete information (i.e., favorable and unfavorable) on its
      mortgagor credit files to Equifax, Experian, and Trans Union Credit Information
      Company, on a monthly basis;

     

    (xx)  Privacy.  With
      regard to each Mortgagor, Countrywide shall at all times comply with all laws
      and regulations regarding use, disclosure and safeguarding of any and all
      customer information, including without limitation the Gramm Leach Bliley Act,
      the Fair Credit Reporting Act and Regulation P.  Countrywide has
      implemented or will implement appropriate measures designed to meet the
      objectives of the Interagency Guidelines Establishing Standards for Safeguarding
      Customer Information, 12 CFR Part 30 Appendix B, and has been and continues
      to
      be engaged in reviewing its information security program, training of staff,
      and
      testing of controls, systems and procedures as required by those
      guidelines;

     

    (yy)  Anti-Money
      Laundering Laws.  Countrywide has complied with all applicable

      required by the Anti-Money Laundering Laws, has conducted the requisite due
      diligence in connection with the origination of each Mortgage Loan for purposes
      of the Anti-Money Laundering Laws, including with respect to the legitimacy
      of
      the applicable Mortgagor and the origin of the assets used by the said Mortgagor
      to purchase the property in question, and maintains, and will maintain,
      sufficient information to identify the applicable Mortgagor for purposes of

    (aaa)  MOM
      Loans; Assignments.  With respect to each MOM Loan, a MIN has been
      assigned by MERS and such MIN is accurately provided on the Mortgage Loan
      Schedule.  The related Assignment of Mortgage to MERS has been duly

      recording office;

      all capitalized terms in this Exhibit B shall have the meanings ascribed to
      them
      in the Fifth Third Purchase Agreement.

      delinquency, exclusive of any period of grace, in any payment by the Mortgagor
      thereunder since the origination of the Mortgage Loan;

    


     

    (iii)  No
      Outstanding Charges. There are no delinquent taxes, ground rents, water

      instruments, recorded in the applicable public recording office or registered
      with the MERS System if necessary to maintain the lien priority of the Mortgage,

      Primary Insurance Policy or LPMI Policy, if any, and the title insurer, to
      the
      extent required by the related policy, and is reflected on the related Mortgage

      Loan Schedule;

     

    (vi)  No
      Defenses.  The Mortgage Note and the Mortgage are not subject to
      any right of rescission, set off, counterclaim or defense, including the defense
      of usury, nor will the operation of any of the terms of the Mortgage Note and/or
      the Mortgage, or the exercise of any right thereunder, render the Mortgage

      fire,
      hazards of extended coverage and such other hazards as are customary in the
      area
      where the Mortgaged Property is located, in an amount not less than the lesser
      of (i) 100% of the replacement cost of all improvements to the Mortgaged
      Property and (ii) either (A) the outstanding principal balance of the Mortgage
      Loan with respect to each first lien Mortgage Loan or (B) with respect to each
      Second Lien Mortgage Loan, the sum of the outstanding principal balance of
      the
      related first lien mortgage loan and the outstanding principal balance of the
      Second Lien Mortgage Loan; provided, however, in no event shall the amount
      of
      insurance be less than the amount necessary to avoid the operation of any
      co-insurance provisions with respect to the Mortgaged Property. All such
      insurance policies contain a standard mortgagee clause naming the Seller, its
      successors and assigns as mortgagee and all premiums thereon have been
      paid.  If the Mortgaged Property is in an area identified on a Flood
      Hazard Map or Flood Insurance Rate Map issued by the Federal Emergency
      Management Agency as having special flood hazards (and such flood insurance
      has
      been made available) a flood insurance policy meeting the requirements of the
      current guidelines of the Federal Insurance Administration is in effect which
      policy conforms to the requirements of Fannie Mae and Freddie
      Mac.  The Mortgage obligates the Mortgagor thereunder to maintain all
      such insurance at the Mortgagor’s cost and expense, and on the Mortgagor’s
      failure to do so, authorizes the holder of the Mortgage to maintain such
      insurance at Mortgagor’s cost and expense and to seek reimbursement therefor
      from the Mortgagor;

     

    (ix)  Compliance
      with Applicable Laws. Any and all requirements of any federal, state or
      local law including, without limitation, usury, truth in lending, real estate
      settlement procedures, consumer credit protection, equal credit opportunity,
      fair housing, disclosure laws and all predatory, abusive and fair lending laws
      applicable to the origination and servicing of mortgage loans of a type similar
      to the Mortgage Loans have been complied with and the consummation of the
      transactions contemplated hereby will not involve the violation of any such
      laws, and the Seller shall maintain in its possession, available for the
      inspection of the Purchaser or its designee, and shall deliver to the Purchaser
      or its designee, upon two Business Days’ request, evidence of compliance with
      such requirements;

     

    (x)  No
      Satisfaction of Mortgage. The 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 satisfaction,
      cancellation, subordination, rescission or release;

     

    (xi)  Valid
      Lien. The related Mortgage is properly recorded and is a valid, existing and
      enforceable (A) first lien and first priority security interest with respect
      to
      each Mortgage Loan which is indicated by the Seller to be a First Lien (as
      reflected on the Mortgage Loan Schedule), or (B) second lien and second priority
      security interest with respect to each Mortgage Loan which is indicated by
      the
      Seller to be a Second Lien (as reflected on the Mortgage Loan Schedule), in
      either case, on the Mortgaged Property, including all improvements on the
      Mortgaged Property subject only to (a) the lien of current real property taxes
      and assessments not yet due and payable, (b) covenants, conditions and
      restrictions, rights of way, easements and other matters of the public record
      as
      of the date of recording being acceptable to mortgage lending institutions
      generally and specifically referred to in the lender’s title insurance policy
      delivered to the originator of the Mortgage Loan and which do not adversely
      affect the Appraised Value of the Mortgaged Property, (c) other matters to
      which
      like properties are commonly subject which do not materially interfere with
      the
      benefits of the security intended to be provided by the Mortgage or the use,
      enjoyment, value or marketability of the related Mortgaged Property and (d)
      with
      respect to each Mortgage Loan which is indicated by the Seller to be a Second
      Lien Mortgage Loan (as reflected on the Mortgage Loan Schedule) a First Lien
      on
      the Mortgaged Property.  Any security agreement, chattel mortgage or
      equivalent document related to and delivered in connection with the Mortgage
      Loan establishes and creates a valid, existing and enforceable (A) first lien
      and first priority security interest with respect to each Mortgage Loan which
      is
      indicated by the Seller to be a First Lien (as reflected on the Mortgage Loan
      Schedule) or (B) second lien and second priority security interest with respect
      to each Mortgage Loan which is indicated by the Seller to be a Second Lien
      Mortgage Loan (as reflected on the Mortgage Loan Schedule), in either case,
      on
      the property described therein and the Seller has full right to sell and assign
      the same to the Purchaser.  The Mortgaged Property was not, as of the
      date of origination of the Mortgage Loan, subject to a mortgage, deed of trust,
      deed to secure debt or other security instrument creating a lien subordinate
      to
      the lien of the Mortgage;

     

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

     

    (xiii)  Legal
      Capacity. All parties to the Mortgage Note and the Mortgage had legal
      capacity to enter into the Mortgage Loan and to execute and deliver the Mortgage
      Note and the Mortgage, and the Mortgage Note and the Mortgage have been duly
      and
      properly executed by such parties.  The Mortgagor is a natural
      person;

     

    (xiv)  Full
      Disbursement of Proceeds. The proceeds of the Mortgage Loan have been fully
      disbursed to or for the account of the Mortgagor and there is no obligation
      for
      the Mortgagee to advance additional funds thereunder and any and all
      requirements as to completion of any on-site or off-site 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
      Mortgage Loan and the recording of the Mortgage have been paid, and the
      Mortgagor is not entitled to any refund of any amounts paid or due to the
      Mortgagee pursuant to the Mortgage Note or Mortgage;

     

    (xv)  Ownership.
      The Seller is the sole legal, beneficial and equitable owner of the Mortgage
      Note and the Mortgage.  The Seller has full right and authority under
      all governmental and regulatory bodies having jurisdiction over such Seller,
      subject to no interest or participation of, or agreement with, any party, to
      transfer and sell the Mortgage Loan to the Purchaser pursuant to this Agreement
      free and clear of any encumbrance or right of others, equity, lien, pledge,
      charge, mortgage, claim, participation interest or security interest of any
      nature (collectively, a “Lien”); and immediately upon the transfers and
      assignments herein contemplated, the Seller shall have transferred and sold
      all
      of its right, title and interest in and to each Mortgage Loan and the Purchaser
      will hold good, marketable and indefeasible title to, and be the owner of,
      each
      Mortgage Loan subject to no Lien;

     

    (xvi)  Doing
      Business. All parties which have had any interest in the Mortgage Loan,
      whether as originator, mortgagee, assignee, pledgee or otherwise, are (or,
      during the period in which they held and disposed of such interest, were):
      (A)
      organized under the laws of such state, or (B) qualified to do business in
      such
      state, or (C) federal savings and loan associations or national banks having
      principal offices in such state, or (D) not doing business in such state so
      as
      to require qualification or licensing, or (E) not otherwise required to be
      licensed in such state.  All parties which have had any interest in
      the Mortgage Loan were in compliance with any and all applicable “doing
      business” and licensing requirements of the laws of the state wherein the
      Mortgaged Property is located or were not required to be licensed in such
      state;

     

    (xvii)  Title
      Insurance. The Mortgage Loan is covered by an American Land Title
      Association (“ALTA”) ALTA lender’s title insurance policy acceptable to Fannie
      Mae and Freddie Mac (which, in the case of an Adjustable Rate Mortgage Loan
      has
      an adjustable rate mortgage endorsement in the form of ALTA 6.0 or 6.1), issued
      by a title insurer acceptable to Fannie Mae and Freddie Mac and qualified to
      do
      business in the jurisdiction where the Mortgaged Property is located, insuring
      (subject to the exceptions contained above in (xi)(a) and (b) and, with respect
      to each Mortgage Loan which is indicated by the Seller to be a Second Lien
      Mortgage Loan (as reflected on the Mortgage Loan Schedule) clause (d)) the
      Seller, its successors and assigns as to the first priority lien of the Mortgage
      in the original principal amount of the Mortgage Loan and, with respect to
      any
      Adjustable Rate Mortgage Loan, against any loss by reason of the invalidity
      or
      unenforceability of the lien resulting from the provisions of the Mortgage
      providing for adjustment in the Mortgage Interest Rate and Monthly
      Payment.  Additionally, such lender’s title insurance policy
      affirmatively insures ingress and egress to and from the Mortgaged Property,
      and
      against encroachments by or upon the Mortgaged Property or any interest
      therein.  The Seller is the sole insured of such lender’s title
      insurance policy, and such lender’s title insurance policy is in full force and
      effect and will be in full force and effect upon the consummation of the
      transactions contemplated by this Agreement.  No claims have been made
      under such lender’s title insurance policy, and no prior holder of the related
      Mortgage, including the Seller, has done, by act or omission, anything which
      would impair the coverage of such lender’s title insurance policy;

     

    (xviii)  No
      Defaults. There is no default, breach, violation or event of acceleration
      existing under the Mortgage or the Mortgage Note and no event which, with the
      passage of time or with notice and the expiration of any grace or cure period,
      would constitute a default, breach, violation or event of acceleration, and
      the
      Seller has not waived any default, breach, violation or event of
      acceleration.  With respect to each Mortgage Loan which is indicated
      by the Seller to be a Second Lien Mortgage Loan (as reflected on the Mortgage
      Loan Schedule) (i) the First Lien is in full force and effect, (ii) there is
      no
      default, breach, violation or event of acceleration existing under such First
      Lien mortgage or the related mortgage note, (iii) 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
      thereunder, and either (A) the First Lien mortgage contains a provision which
      allows or (B) applicable law requires, the mortgagee under the Second Lien
      Mortgage Loan to receive notice of, and affords such mortgagee an opportunity
      to
      cure any default by payment in full or otherwise under the First Lien
      mortgage;

     

    (xix)  No
      Mechanics’ Liens. 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) affecting the related Mortgaged Property
      which are or may be liens prior to, or equal or coordinate with, the lien of
      the
      related Mortgage;

     

    (xx)  Origination.
      The Mortgage Loan was originated by the Seller or by a savings and loan
      association, a savings bank, a commercial bank or similar banking institution
      which is supervised and examined by a federal or state authority, or by a
      mortgagee approved as such by the Secretary of HUD;

     

    (xxi)  Payment
      Terms. Payments on the Mortgage Loan shall commence (with respect to any
      newly originated Mortgage Loans) or commenced no more than sixty days after
      the
      proceeds of the Mortgage Loan were disbursed.  The Mortgage Loan bears
      interest at the Mortgage Interest Rate.  With respect to each Mortgage
      Loan, the Mortgage Note is payable on the first day of each month in Monthly
      Payments, which, (A) in the case of a Fixed Rate Mortgage Loan, are sufficient
      to fully amortize the original principal balance over the original term thereof
      (other than with respect to a Mortgage Loan identified on the related Mortgage
      Loan Schedule as an interest-only Mortgage Loan during the interest-only period
      or a Mortgage Loan which is identified on the related Mortgage Loan Schedule
      as
      a Balloon Mortgage Loan)  and to pay interest at the related Mortgage
      Interest Rate, and (B) in the case of an Adjustable Rate Mortgage Loan, are
      changed on each Adjustment Date, and in any case, are sufficient to fully
      amortize the original principal balance over the original term thereof (other
      than with respect to a Mortgage Loan identified on the related Mortgage Loan
      Schedule as an interest-only Mortgage Loan during the interest-only period
      or a
      Mortgage Loan which is identified on the related Mortgage Loan Schedule as
      a
      Balloon Mortgage Loan) and to pay interest at the related Mortgage Interest
      Rate.  The Index for each Adjustable Rate Mortgage Loan is as defined
      in the related Mortgage Loan Schedule.  With respect to each Mortgage
      Loan identified on the Mortgage Loan Schedule as an interest-only Mortgage
      Loan,
      the interest-only period shall not exceed the period specified on the Mortgage
      Loan Schedule and following the expiration of such interest-only period, the
      remaining Monthly Payments shall be sufficient to fully amortize the original
      principal balance over the remaining term of the Mortgage Loan.  With
      respect to each Balloon Mortgage Loan, the Mortgage Note requires a monthly
      payment which is sufficient to fully amortize the original principal balance
      over the original term thereof and to pay interest at the related Mortgage
      Interest Rate and requires a final Monthly Payment substantially greater than
      the preceding monthly payment which is sufficient to repay the remaining unpaid
      principal balance of the Balloon Mortgage Loan as of the Due Date of such
      Monthly Payment.  No Balloon Mortgage Loan has an original stated
      maturity of less than seven (7) years. The Mortgage Note does not permit
      negative amortization.  No Mortgage Loan had an original term to
      maturity of more than thirty (30) years;

     

    (xxii)  Origination
      and Collection Practices; Escrow Deposits. The origination, servicing and
      collection practices used by the Seller with respect to each Mortgage Note
      and
      Mortgage, including without limitation the establishment, maintenance and
      servicing of the Escrow Accounts and Escrow Payments, if any, since origination
      have been in all respects legal, proper, prudent and customary in the mortgage
      origination and servicing industry.  The Mortgage Loan has been
      serviced by the Seller and any predecessor servicer in accordance with all
      applicable laws, rules and regulations, the terms of the Mortgage Note and
      Mortgage, and the Fannie Mae and Freddie Mac servicing guides.  With
      respect to escrow deposits and Escrow Payments (other than with respect to
      each
      Mortgage Loan which is indicated by the Seller to be a Second Lien Mortgage
      Loan
      and for which the mortgagee under the First Lien is collecting Escrow Payments
      (as reflected on the Mortgage Loan Schedule)), if any, all such payments are
      in
      the possession of, or under the control of, the Seller and there exist no
      deficiencies in connection therewith for which customary arrangements for
      repayment thereof have not been made.  No escrow deposits or Escrow
      Payments or other charges or payments due the Seller have been capitalized
      under
      any Mortgage or the related Mortgage Note and no such escrow deposits or Escrow
      Payments are being held by the Seller for any work on a Mortgaged Property
      which
      has not been completed;

     

    (xxiii)  Mortgaged
      Property Undamaged. As of the origination of the Mortgage Loan and, to the
      best of the Seller’s knowledge, as of the Closing Date, the Mortgaged Property
      is free of damage and waste and is in good repair, and there is no proceeding
      pending or threatened for the total or partial condemnation thereof nor is
      such
      a proceeding currently occurring;

     

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

     

    (xxv)  Appraisal.
      Unless otherwise set forth on the Mortgage Loan Schedule, the Mortgage File
      contains an appraisal of the related Mortgaged Property which, (a) with respect
      to First Lien Mortgage Loans, was on appraisal form 1004 or form 2055 with
      an
      interior inspection, or (b) with respect to Second Lien Mortgage Loans, was
      on
      appraisal form 704, 2065 or 2055 with an exterior only inspection, and (c)
      with
      respect to (a) or (b) above, was made and signed, prior to the approval of
      the
      Mortgage Loan application, by a qualified appraiser, duly appointed by the
      Seller, who had no interest, direct or indirect in the Mortgaged Property or
      in
      any loan made on the security thereof, whose compensation is not affected by
      the
      approval or disapproval of the Mortgage Loan and who met the minimum
      qualifications of Fannie Mae and Freddie Mac.  Each appraisal of the
      Mortgage Loan was made in accordance with the relevant provisions of the
      Financial Institutions Reform, Recovery, and Enforcement Act of
      1989;

     

    (xxvi)  Deeds
      of Trust. 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 Purchaser to the trustee under the
      deed of trust, except in connection with a trustee’s sale after default by the
      Mortgagor;

     

    (xxvii)  Construction
      or Rehabilitation of Mortgaged Property. No Mortgage Loan was made in
      connection with (a) the construction or rehabilitation of a Mortgaged Property
      or (b) facilitating the trade-in or exchange of a Mortgaged
      Property;

     

    (xxviii)   LTV;
      CLTV. The Loan-to-Value Ratio of any Mortgage Loan at origination was not
      more than 95% and the CLTV of any Mortgage Loan at origination was not more
      than
      100%;  Each Mortgage Loan (other than any Mortgage Loan underwritten
      pursuant to the Seller’s Subprime Underwriting Guidelines) with an original
      Loan-to-Value Ratio at origination greater than 80% is and will be subject
      to a
      Primary Insurance Policy, issued by a Qualified Insurer, which insures that
      portion of the Mortgage Loan in excess of the portion of the Appraised Value
      of
      the Mortgaged Property as required by Fannie Mae.  All provisions of
      such Primary Insurance Policy have been and are being complied with, such policy
      is in full force and effect, and all premiums due thereunder have been
      paid.  Any Mortgage subject to any such Primary Insurance Policy
      obligates the Mortgagor thereunder to maintain such insurance and to pay all
      premiums and charges in connection therewith.  The Mortgage Interest
      Rate for the Mortgage Loan does not include any such insurance
      premium.  If a Mortgage Loan is identified on the Mortgage Loan
      Schedule as subject to a Lender Paid Mortgage Insurance Policy, such policy
      insures that portion of the Mortgage Loan set forth in the LPMI
      Policy.  All provisions of any such LPMI Policy have been and are
      being complied with, such policy is in full force and effect, and all premiums
      due thereunder have been paid.  The Mortgage Interest Rate for the
      Mortgage Loan does not include the insurance premium for any LPMI
      Policy;

     

    (xxix)   Occupancy
      of the Mortgaged Property. 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 and fire underwriting certificates, have been made
      or
      obtained from the appropriate authorities.  No improvement located on
      or being part of any Mortgaged Property is in violation of any applicable zoning
      and subdivision law, ordinance  or regulation;

     

    (xxx)  No
      Error, Omission, Fraud etc.  No error, omission,
      misrepresentation, negligence, fraud or similar occurrence with respect to
      a
      Mortgage Loan has taken place on the part of any 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;

     

    (xxxi)  Consolidation
      of Advances; Lien Priority. Any principal advances made to the Mortgagor
      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 reflected
      on the Mortgage Loan Schedule.  The lien of the Mortgage securing the
      consolidated principal amount is expressly insured as having (A) first lien
      priority with respect to each Mortgage Loan which is indicated by the Seller
      to
      be a First Lien (as reflected on the Mortgage Loan Schedule), or (B) second
      lien
      priority with respect to each Mortgage Loan which is indicated by the Seller
      to
      be a Second Lien Mortgage Loan (as reflected on the Mortgage Loan Schedule),
      in
      either case, by a title insurance policy, an endorsement to the policy insuring
      the mortgagee’s consolidated interest or by other title evidence acceptable to
      Fannie Mae and Freddie Mac.  The consolidated principal amount does
      not exceed the original principal amount of the Mortgage Loan;

     

    (xxxii)   Environmental
      Matters. The Mortgaged Property is in material compliance with all
      applicable environmental laws pertaining to environmental hazards including,
      without limitation, asbestos, and neither the Seller nor, to the Seller’s
      knowledge, the related Mortgagor, has received any notice of any violation
      or
      potential violation of such law;

     

    (xxxiii)   HOEPA.
      No Mortgage Loan is (a) subject to the provisions of the Homeownership and
      Equity Protection Act of 1994 as amended (“HOEPA”), or has an “annual percentage
      rate” or “total points and fees” payable by the borrower (as each term is
      defined under HOEPA) that equals or exceeds the applicable thresholds defined
      under HOEPA (Section 32 of Regulation Z, 12 C.F.R. Section 226.32(a)(1)(i)
      and
      (ii)), (b) a “high cost” mortgage loan, “covered” mortgage loan (excluding home
      loans defined as “covered home loans” in the New Jersey Home Ownership Security
      Act of 2002 that were originated between November 26, 2003 and July 7, 2004),
      “high risk home” mortgage loan, or “predatory” mortgage loan or any other
      comparable term, no matter how defined under any federal, state or local law,
      (c) subject to any comparable federal, state or local statutes or regulations,
      or any other statute or regulation providing for heightened regulatory scrutiny,
      assignee liability to holders of such mortgage loans or additional legal
      liability for mortgage loans having high interest rates, points and/or fees,
      or
      (d) a High Cost Loan or Covered Loan, as applicable (as such terms are defined
      in the current Standard & Poor’s LEVELS® Glossary Revised, Appendix
      E);

     

    (xxxiv)   Due-On-Sale.
      Each Mortgage contains an enforceable provision for the acceleration of the
      payment of the unpaid principal balance of the related Mortgage Loan in the
      event the related Mortgaged Property is sold or transferred without the prior
      consent of the mortgagee thereunder;

     

    (xxxv)  Second
      Liens. With respect to each Mortgage Loan which is a Second Lien, (i) the
      related First Lien does not provide for negative amortization, (ii) either
      no
      consent for the Mortgage Loan is required by the holder of the First Lien or
      such consent has been obtained and is contained in the Mortgage File and (iii)
      such Second Lien is on a Residential Dwelling that is (or will be) the principal
      residence of the Mortgagor upon origination of the Second Lien;

      Secretary of State in connection with Massachusetts House Bill 4880 (2004))
      unless either (1) (a) the related Mortgage Interest Rate (that would be
      effective once the introductory rate expires, with respect to Adjustable Rate
      Mortgage Loans) did or would not exceed by more than 2.25% the yield on United
      States Treasury securities having comparable periods of maturity to the maturity
      of the related Mortgage Loan as of the fifteenth day of the month immediately
      preceding the month in which the application for the extension of credit was
      received by the related lender or (b) the Mortgage Loan is an “open-end home

      for determining “borrower's interest,” and otherwise complies in all material
      respects with the laws of the Commonwealth of Massachusetts;

      nature of an “average” or “yield spread premium” to a mortgage broker or a like
      Person which has not been fully disclosed to the Mortgagor;

     

    (lxi)  Acceptable
      Investment. The Seller has no knowledge of any circumstances or condition
      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, cause the Mortgage Loan to
      become delinquent, cause the Mortgage Loan to not be paid in full when due,
      or
      adversely affect the value of the Mortgage Loan;

     

    (lxii)  No
      Notification of Prepayments in Full. The Mortgage Loan was not prepaid in
      full prior to the Closing Date and the Seller has not received notification
      from
      a Mortgagor that a prepayment in full shall be made after the Closing
      Date;

     

    (lxiii)  Limitation
      on number of Mortgage Notes per Borrower. No Mortgagor is the obligor on
      more than two Mortgage Notes;

     

    (lxiv)  Prepayment
      Charges; With respect to any Mortgage Loan that contains a provision
      permitting imposition of a Prepayment Charge upon a Principal Prepayment prior
      to maturity: (i) prior to the Mortgage Loan’s origination, the Mortgagor agreed
      to such Prepayment Charge in exchange for a monetary benefit, including but
      not
      limited to a Mortgage Interest Rate or fee reduction, (ii) prior to the Mortgage
      Loan’s origination, the Mortgagor was offered the option of obtaining a Mortgage
      Loan that did not require payment of a Prepayment Charge and the originator
      of
      the Mortgage Loan had a written policy of offering borrowers, or requiring
      third-party brokers to offer borrowers, the option of obtaining a mortgage
      loan
      that did not require the payment of a Prepayment Charge, (iii) the Prepayment
      Charge is disclosed to the Mortgagor in the Mortgage Loan Documents pursuant
      to
      state and federal law applicable to the Mortgage Loan, (iv) for Mortgage Loans
      originated on or after October 1, 2002, the duration of the prepayment period
      shall not exceed three (3) years from the date of the Mortgage Note, unless
      the
      Mortgage Loan was modified to reduce the prepayment period to no more than
      three
      years from the date of the Mortgage Note and the Mortgagor was notified in
      writing of such reduction in the prepayment period, (v) no Mortgage Loan
      originated prior to October 1, 2002 has a Prepayment Charge longer than five
      years and (vi) notwithstanding any state or federal law to the contrary, the
      Seller shall not impose such Prepayment Charge in any instance when the Mortgage
      Loan is accelerated or paid off in connection with the workout of a delinquent
      mortgage or due to the Mortgagor’s default.  Each Prepayment Charge is
      permissible, collectable and enforceable.

     

    (lxv)  No
      Predatory Lending. No predatory, abusive or deceptive lending practices,
      including but not limited to, the extension of credit to a Mortgagor without
      regard for the Mortgagor’s ability to repay the Mortgage Loan and the extension
      of credit to a Mortgagor which has no tangible net benefit to the Mortgagor,
      were employed in connection with the origination of the Mortgage
      Loan.  Each Mortgage Loan is in compliance with the anti-predatory
      lending eligibility for purchase requirements of Fannie Mae’s Selling Guide. No
      Mortgagor was encouraged or required to select a Mortgage Loan product offered
      by the Mortgage Loan’s originator which is a higher cost product designed for
      less creditworthy borrowers, unless at the time of the Mortgage Loan’s
      origination, such Mortgagor did not qualify taking into account credit history
      and debt to income ratios for a lower cost credit product then offered by the
      Mortgage Loan’s originator or any affiliate of the Mortgage Loan’s
      originator.  If, at the time of the related loan application, the
      Mortgagor may have qualified for a lower cost credit product then offered by
      any
      mortgage lending affiliate of the Mortgage Loan’s originator, the Mortgage
      Loan’s originator referred the Mortgagor’s application to such affiliate for
      underwriting consideration;

     

    (lxvi)  Underwriting
      Methodology. The methodology used in underwriting the extension of credit
      for each Mortgage Loan employs objective mathematical principles which relate
      the Mortgagor’s income, assets and liabilities to the proposed payment and such
      underwriting methodology did and does not rely solely on the extent of the
      Mortgagor’s equity in the collateral as the principal determining factor in
      approving such credit extension.  Such underwriting methodology
      confirmed that at the time of origination (application/approval) the Mortgagor
      had a reasonable ability to make timely payments on the Mortgage
      Loan.

     

    (lxvii)  Points
      and Fees Disclosed. All
      points, fees and charges, including finance charges (whether or not financed,
      assessed, collected or to be collected), in connection with the origination
      and
      servicing of any Mortgage Loan were disclosed in writing to the related
      Mortgagor in accordance with applicable state and federal law and regulation
      and
      no related Mortgagor was charged “points and fees” (whether or not financed) in
      an amount that exceeds the greater of (1) 5% of the principal amount of such
      loan or (2) $1,000.  For the purposes of this representation, “points
      and fees” (a) include origination, underwriting, broker and finder’s fees and
      charges that the lender imposed as a condition of making the Mortgage Loan,
      whether they are paid to the lender or a third party; and (b) exclude bona
      fide
      discount points, fees paid for actual services rendered in connection with
      the
      origination of the Mortgage Loan (such as attorneys’ fees, notaries fees and
      fees paid for property appraisals, credit reports, surveys, title examinations
      and extracts, flood and tax certifications, and home inspections) and the cost
      of mortgage insurance or credit-risk price adjustments; the costs of title,
      hazard, and flood insurance policies; state and local transfer taxes or fees;
      escrow deposits for the future payment of taxes and insurance premiums;
and other miscellaneous fees and charges, which miscellaneous fees and
      charges, in total, do not exceed
      0.25 percent of the loan amount);

     

    (lxviii)  Full
      File Credit Reporting (Fannie Mae). The Seller will transmit full-file
      credit reporting data for each Mortgage Loan pursuant to Fannie Mae Guide
      Announcement 95-19 and for each Mortgage Loan, Seller agrees it shall report
      one
      of the following statuses each month as follows: new origination, current,
      delinquent (30-, 60-, 90-days, etc.), foreclosed, or charged-off;

     

    (lxix)  No
      Credit Life Policies. No Mortgagor was required to purchase any single
      premium credit insurance policy (e.g. life, mortgage, disability, accident,
      unemployment, property or health insurance product) or debt cancellation
      agreement as a condition of obtaining the extension of credit.  No
      Mortgagor obtained a prepaid single premium credit insurance policy (e.g. life,
      mortgage, disability, accident, unemployment, property or health insurance
      product) in connection with the origination of the Mortgage Loan, and no
      proceeds from any Mortgage Loan were used to purchase single-premium credit
      insurance policies or debt cancellation agreements as part of the origination
      of, or as a condition to closing, such Mortgage Loan;

     

    (lxx)  Full
      File Credit Reporting (Past Practice; Future Practice). The Seller and any
      predecessor servicer has fully furnished, in accordance with the Fair Credit
      Reporting Act and its implementing regulations, accurate and complete
      information (e.g., favorable and unfavorable) on its borrower credit files
      to
      Equifax, Experian and Trans Union Credit Information Company (three of the
      credit repositories) on a monthly basis; and the Seller will fully furnish,
      in
      accordance with the Fair Credit Reporting Act and its implementing regulations,
      accurate and complete information (e.g., favorable and unfavorable) on its
      borrower credit files to Equifax, Experian and Trans Credit Information Company
      (three of the credit repositories), on a monthly basis; and

     

    (lxxi)  No
      Arbitration. With respect to each Mortgage Loan, neither the related
      Mortgage nor the related Mortgage Note requires the Mortgagor to submit to
      arbitration to resolve any dispute arising out of or relating in any way to
      the
      Mortgage Loan;  No Mortgagor agreed to submit to arbitration to
      resolve any dispute arising out of or relating in any way to the Mortgage
      Loan.

                (i)    

            	
              Mortgage
                Loans as Described.

            


    

     

    The
      information set forth in the respective Mortgage Loan Schedule and the

      Current.

    


    All
      payments required to be made up to the related Cut-off Date for the Mortgage
      Loan under the terms of the Mortgage Note have been made and

      and payable.  The Seller has not advanced funds, or induced, or
      solicited directly or indirectly, the payment of any amount required under
      the
      Mortgage Loan, except for interest accruing from the date of the Mortgage Note
      or date of disbursement of the Mortgage Loan proceeds, whichever is later,
      to
      the day which precedes by one month the Due Date of the first installment of
      principal and interest;

    


    (iv)           Original
      Terms Unmodified.

      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
      or registered with the MERS System, if necessary, to protect the interests
      of
      the Purchaser and which has been delivered to the Custodian.  The
      substance of any such waiver, alteration or modification has been approved
      by
      the issuer of any related PMI Policy and the title insurer, to the extent
      required by the policy, and its terms are reflected on the related Mortgage
      Loan

    (v)           No
      Defenses.

    


    The
      Mortgage Loan is not subject to any right of rescission, set-off, counterclaim
      or defense, including without limitation the defense of usury, nor will the
      operation of any of the terms of the Mortgage Note or the Mortgage, or the
      exercise of any right thereunder, render either the Mortgage Note or the
      Mortgage unenforceable, in whole or in part, or subject to any right of
      rescission, set-off, counterclaim or defense, including without limitation
      the
      defense of usury, and no such right of rescission, set-off, counterclaim or
      defense has been asserted with respect thereto;

      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 satisfaction, release, cancellation, subordination or
      rescission;

    


    (vii)           Validity
      of Mortgage Documents.

    


    The
      Mortgage Note and the Mortgage and related documents 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 had legal capacity to enter into the Mortgage Loan and to execute
      and
      deliver the Mortgage Note and the Mortgage, and the Mortgage Note and the
      Mortgage have been duly and properly executed by such parties.

    


    With
      respect to each Cooperative Loan, the Mortgage Note, the Mortgage, the Pledge
      Agreement, and related documents 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, the Mortgage, the Pledge
      Agreement, the Proprietary Lease, the Stock Power, Recognition Agreement and
      the
      Assignment of Proprietary Lease had legal capacity to enter into the Mortgage
      Loan and to execute and deliver such documents, and such documents have been
      duly and properly executed by such parties;

    


    (viii)        No
      Fraud.

    


    No
      error,
      omission, misrepresentation, negligence, fraud or similar occurrence with
      respect to a Mortgage Loan has taken place on the part of the Seller, or the
      Mortgagor (except with respect to the accuracy of Unverified Information),
      or to
      the best of the Seller’s knowledge, any appraiser, any builder, or any
      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;

    


    (ix)           Compliance
      with Applicable Laws.

    


    Any
      and
      all requirements of any federal, state or local law including, without
      limitation, usury, truth-in-lending, real estate settlement procedures, consumer
      credit protection, equal credit opportunity, disclosure or predatory and abusive
      lending laws applicable to the Mortgage Loan have been complied
      with.  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 and fire underwriting certificates, have been
      made
      or obtained from the appropriate authorities;

    


    (x)           Location
      and Type of Mortgaged Property.

    


    The
      Mortgaged Property is located in the state identified in the related Mortgage
      Loan Schedule and consists of a contiguous 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 condominium project, or an
      individual unit in a planned unit development, or a townhouse, or a cooperative,
      provided, however, that any condominium project or planned unit development
      shall conform with the applicable Fannie Mae or Freddie Mac requirements, or
      the
      Underwriting Guidelines with respect to the Seller Mortgage Loans (other than
      the exceptions identified for Exception Mortgage Loans on the related Assignment
      and Conveyance Agreement) or the Third-Party Underwriting Guidelines with
      respect to Third-Party Mortgage Loans, as applicable, regarding such dwellings,
      and no residence or dwelling is a mobile home.  As of the respective
      appraisal date for each Mortgaged Property, any Mortgaged Property being used
      for commercial purposes conforms to the Underwriting Guidelines with respect
      to
      the Seller Mortgage Loans (other than the exceptions identified for Exception
      Mortgage Loans on the related Assignment and Conveyance Agreement) or the
      Third-Party Underwriting Guidelines with respect to Third-Party Mortgage Loans,
      as applicable and, to the best of the Seller’s knowledge, since the date of such
      appraisal, no portion of the Mortgaged Property has been used for commercial
      purposes outside of the Underwriting Guidelines;

    


    (xi)           Valid
      First Lien.

    


    The
      Mortgage is a valid, subsisting and enforceable first lien on the Mortgaged
      Property, including all buildings on the Mortgaged Property and all
      installations and mechanical, electrical, plumbing, heating and air conditioning
      systems located in or annexed to such buildings, and all additions, alterations
      and replacements made at any time with respect to the foregoing.  The
      lien of the Mortgage is subject only to:

    


    (1)           the
      lien of current real property taxes and assessments not yet due and
      payable;

    


    (2)           covenants,
      conditions and restrictions, rights of way, easements and other matters of
      the
      public record as of the date of recording acceptable to mortgage lending
      institutions generally and specifically referred to in the lender's title
      insurance policy delivered to the originator of the Mortgage Loan and (i)
      referred to or otherwise considered in the appraisal made for the originator
      of
      the Mortgage Loan and (ii) which do not adversely affect the Appraised Value
      of
      the Mortgaged Property set forth in such appraisal; and

    


    (3)           other
      matters to which like properties are commonly subject which do not materially
      interfere with the benefits of the security intended to be provided by the
      mortgage or the use, enjoyment, value or marketability of the related Mortgaged
      Property.

    


    Any
      security agreement, chattel mortgage or equivalent document related to and
      delivered in connection with the Mortgage Loan establishes and creates a valid,
      subsisting and enforceable first lien and first priority security interest
      on
      the property described therein and the Seller has full right to sell and assign
      the same to the Purchaser.

    


    With
      respect to each Cooperative Loan, each Pledge Agreement creates a valid,
      enforceable and subsisting first security interest in the Cooperative Shares
      and
      Proprietary Lease, subject only to (i) the lien of the related Cooperative
      for
      unpaid assessments representing the Mortgagor’s pro rata share of the
      Cooperative’s payments for its blanket mortgage, current and future real
      property taxes, insurance premiums, maintenance fees and other assessments
      to
      which like collateral is commonly subject and (ii) other matters to which like
      collateral is commonly subject which do not materially interfere with the
      benefits of the security intended to be provided by the Pledge Agreement;
      provided, however, that the appurtenant Proprietary Lease may be subordinated
      or
      otherwise subject to the lien of any mortgage on the Project;

    


    (xii)           Full
      Disbursement of Proceeds.

    


    The
      proceeds of the Mortgage Loan have been fully disbursed, except for escrows
      established or created due to seasonal weather conditions, and there is no
      requirement for future advances thereunder.  All costs, fees and
      expenses incurred in making or closing the Mortgage Loan and the recording
      of
      the Mortgage were paid, and the Mortgagor is not entitled to any refund of
      any
      amounts paid or due under the Mortgage Note or Mortgage;

    


    (xiii)         Consolidation
      of Future Advances.

    


    Any
      future advances made prior to the related 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 reflected on the related Mortgage Loan Schedule. The lien of
      the
      Mortgage securing the consolidated principal amount is expressly insured as
      having first lien priority (or second lien priority for each Mortgage Loan
      identified on the such Mortgage Loan Schedule as being a Second Lien Mortgage
      Loan) by a title insurance policy, an endorsement to the policy insuring the
      mortgagee’s consolidated interest or by other title evidence acceptable to
      Fannie Mae or Freddie Mac; the consolidated principal amount does not exceed
      the
      original principal amount of the Mortgage Loan; the Seller shall not make future
      advances after the related Cut-off Date;

    


    (xiv)        Ownership.

    


    The
      Seller is the sole owner of record and holder of the Mortgage Loans and the
      related Mortgage Note and the Mortgage are not assigned or pledged, and the
      Seller has good and marketable title thereto and has full right and authority
      to
      transfer and sell the Mortgage Loan to the Purchaser.  The Seller is
      transferring the Mortgage Loan free and clear of any and all encumbrances,
      liens, pledges, equities, participation interests, claims, charges or security
      interests of any nature encumbering such Mortgage Loan;

    


    (xv)           Origination/Doing
      Business.

    


    The
      Mortgage Loan was originated by a savings and loan association, a savings bank,
      a commercial bank, a credit union, an 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. All parties which have had
      any
      interest in the Mortgage Loan, whether as mortgagee, assignee, pledgee or
      otherwise, are (or, during the period in which they held and disposed of such
      interest, were)  (1) in compliance with any and all applicable
      licensing requirements of the laws of the state wherein the Mortgaged Property
      is located, and (2) organized under the laws of such state, or (3) qualified
      to
      do business in such state, or (4) federal savings and loan associations or
      national banks having principal offices in such state, or (5) not doing business
      in such state;

    


    (xvi)         LTV,
      PMI Policy.

    


    Each
      Mortgage Loan has an LTV as specified on the related Mortgage Loan Schedule.
      Except as indicated on the
Mortgage
      Loan Schedule and
      on the Data File, if
      the LTV of the Mortgage Loan was greater than 80% at the time of origination,
      a
      portion of the unpaid principal balance of the Mortgage Loan is and will be
      insured as to payment defaults by a PMI Policy.  If the Mortgage Loan
      is insured by a PMI Policy for which the Mortgagor pays all premiums, the
      coverage will remain in place until (i) the LTV decreases to 78% or (ii) the
      PMI
      Policy is otherwise terminated pursuant to the Homeowners Protection Act of
      1998, 12 USC §4901, et seq.  All provisions of such PMI Policy or LPMI
      Policy have been and are being complied with, such policy is in full force
      and
      effect, and all premiums due thereunder have been paid.  The Qualified
      Insurer has a claims paying ability acceptable to Fannie Mae or Freddie
      Mac.  Any Mortgage Loan subject to a PMI Policy or LPMI Policy
      obligates the Mortgagor or the Seller to maintain the PMI Policy or LPMI Policy
      and to pay all premiums and charges in connection therewith.  The
      Mortgage Interest Rate for the Mortgage Loan as set forth on the related
      Mortgage Loan Schedule is net of any such insurance premium;

     

    (xvii)       Title
      Insurance.

    


    The
      Mortgage Loan is covered by an ALTA lender's title insurance policy (or in
      the
      case of any Mortgage Loan secured by a Mortgaged Property located in a
      jurisdiction where such policies are generally not available, an opinion of
      counsel of the type customarily rendered in such jurisdiction in lieu of title
      insurance) or other generally acceptable form of policy of insurance acceptable
      to Fannie Mae or Freddie Mac, issued by a title insurer acceptable to Fannie
      Mae
      or Freddie Mac and qualified to do business in the jurisdiction where the
      Mortgaged Property is located, insuring the Seller, its successors and assigns,
      as to the first priority lien (or second priority if such Mortgage Loan is
      a
      Second Lien Mortgage Loan) of the Mortgage in the original principal amount
      of
      the Mortgage Loan, subject only to the exceptions contained in clauses (1),
      (2)
      and (3) of subsection (xi) of this Section 6(b) with respect to each First
      Lien
      Mortgage Loan and subject only to the exceptions contained in clauses (1),
      (2),
      (3) and (4) of subsection (xlxii) with respect to each Second Lien Mortgage
      Loan, and against any loss by reason of the invalidity or unenforceability
      of
      the lien resulting from the provisions of the Mortgage providing for adjustment
      to the Mortgage Interest Rate and Monthly Payment. Additionally, such lender’s
      title insurance policy includes no exceptions regarding ingress, egress or
      encroachments that impact the value or the marketability of the Mortgaged
      Property. The Seller is the sole insured of such lender's title insurance
      policy, and such lender's title insurance policy is in full force and effect
      and
      will be in force and effect upon the consummation of the transactions
      contemplated by this Agreement. No claims have been made under such lender's
      title insurance policy, and no prior holder of the Mortgage, including the
      Seller, has done, by act or omission, anything which would impair the coverage
      of such lender's title insurance policy;

    


    (xviii)      No
      Defaults.

    


    There
      is
      no default, breach, violation or event of acceleration existing under the
      Mortgage or the Mortgage Note and no event which, with the passage of time
      or
      with notice and the expiration of any grace or cure period, would constitute
      a
      default, breach, violation or event of acceleration, and neither the Seller
      nor
      its predecessors have waived any default, breach, violation or event of
      acceleration;

    


    (xix)         No
      Mechanics' Liens.

    


    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 which
      are not insured against by the title insurance policy referenced in Paragraph (xvii) above;

    


    (xx)           Location
      of Improvements; No Encroachments.

    


    Except
      as
      insured against by the title insurance policy referenced in subsection (xvii)
      above, 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;

    


    (xxi)          Payment
      Terms.

    


    Except
      with respect to the Interest Only Mortgage Loans, principal payments commenced
      no more than 60 days after the funds were disbursed to the Mortgagor in
      connection with the Mortgage Loan.  The Mortgage Loans have an
      original term to maturity of not more than 30 years (except with respect to
      certain Balloon Loans or Interest Only Mortgage Loans), with interest payable
      in
      arrears on the first day of each month.  As to each adjustable rate
      Mortgage Loan on each applicable Adjustment Date, the Mortgage Interest Rate
      will be adjusted to equal the sum of the Index plus the applicable Gross Margin,
      rounded up or down to the nearest multiple of 0.125% indicated by the Mortgage
      Note; provided that the Mortgage Interest Rate will not increase or decrease
      by
      more than the Periodic Interest Rate Cap on any Adjustment Date, and will in
      no
      event exceed the maximum Mortgage Interest Rate or be lower than the minimum
      Mortgage Interest Rate listed on the related Mortgage Note for such Mortgage
      Loan.  As to each adjustable rate Mortgage Loan that is not an
      Interest Only Mortgage Loan, each Mortgage Note requires a monthly payment
      which
      is sufficient, during the period prior to the first adjustment to the Mortgage
      Interest Rate, to fully amortize the outstanding principal balance as of the
      first day of such period over the then remaining term of such Mortgage Note
      and
      to pay interest at the related Mortgage Interest Rate.  As to each
      adjustable rate Mortgage Loan, if the related Mortgage Interest Rate changes
      on
      an Adjustment Date or, with respect to an Interest Only Mortgage Loan, on an
      Adjustment Date following the related interest only period, the then outstanding
      principal balance will be reamortized over the remaining life of such Mortgage
      Loan.  No Mortgage Loan contains terms or provisions which would
      result in negative amortization.  With respect to each Balloon Loan,
      the Mortgage Loan is payable in equal monthly installments of principal and
      interest based on a fifteen (15), thirty (30) or forty (40) year amortization
      schedule, as set forth in the related Mortgage Note, and a final lump sum
      payment substantially greater than the preceding Monthly Payment is required
      which is sufficient to amortize the remaining principal balance of the Balloon
      Loan.  No Balloon Loan has an original stated maturity of less than
      seven (7) years;

    


    (xxii)        Customary
      Provisions.

    


    The
      Mortgage and related Mortgage Note contain customary and enforceable provisions
      such as to render the rights and remedies of the holder thereof adequate for
      the
      realization against the Mortgaged Property of the benefits of the security
      provided thereby, including, (1) in the case of a Mortgage designated as a
      deed
      of trust, by trustee's sale, and (2) otherwise by judicial
      foreclosure.  There is no homestead or other exemption available to a
      Mortgagor which would interfere with the right to sell the Mortgaged Property
      at
      a trustee's sale or the right to foreclose the Mortgage;

    


    (xxiii)       Occupancy
      of the Mortgaged Property.

    


    As
      of the
      date of origination, the Mortgaged Property was in good repair and was lawfully
      occupied under applicable law;

    


    (xxiv)       No
      Additional Collateral.

    


    Except
      in
      the case of a Pledged Asset Mortgage Loan and as indicated on the related Data
      File, the Mortgage Note is not and has not been secured by any collateral,
      pledged account or other security except the lien of the corresponding Mortgage
      and the security interest of any applicable security agreement or chattel
      mortgage referred to in subsection (xi) above;

    


    (xxv)        Deeds
      of Trust.

    


    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 Mortgagee to the trustee under the deed of trust, except in
      connection with a trustee's sale after default by the Mortgagor;

    


    (xxvi)       Acceptable
      Investment.

    


    The
      Seller has no knowledge of any circumstances or conditions with respect to
      the
      Mortgage Loan, the Mortgaged Property, the Mortgagor or the Mortgagor's credit
      standing that can reasonably be expected to cause private institutional
      investors to regard the Mortgage Loan as an unacceptable investment, cause
      the
      Mortgage Loan to become delinquent, or adversely affect the value or
      marketability of the Mortgage Loan;

    


    (xxvii)      Transfer
      of Mortgage Loans.

    


    If
      the
      Mortgage Loan is not a MERS Mortgage Loan, the Assignment of Mortgage, upon
      the
      insertion of the name of the assignee and recording information, is in
      recordable form and is acceptable for recording under the laws of the
      jurisdiction in which the Mortgaged Property is located;

    


    (xxviii)     Mortgaged
      Property Undamaged.

    


    The
      Mortgaged Property is undamaged by waste, fire, earthquake or earth movement,
      windstorm, flood, tornado or other casualty so as to affect adversely the value
      of the Mortgaged Property as security for the Mortgage Loan or the use for
      which
      the premises were intended;

    


    (xxix)        Collection
      Practices; Escrow Deposits.

    


    The
      origination, servicing and collection practices used with respect to the
      Mortgage Loan have been in accordance with Accepted Servicing Practices, and
      have been in all material respects legal and proper.  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.  No escrow deposits or Escrow Payments or other charges or
      payments due the Seller have been capitalized under the Mortgage
      Note;

    


    (xxx)         No
      Condemnation.

    


    There
      is
      no proceeding pending or to the best of the Seller’s knowledge threatened for
      the total or partial condemnation of the related Mortgaged
      Property;

    


    (xxxi)       The
      Appraisal.

    


    The
      Servicing File include an appraisal, with the exception of any Time$aver®
Mortgage Loan (which at the original origination were on form 1004 or form
      2055
      with interior inspections), of the related Mortgaged Property.  The
      appraisal was conducted by an 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 Mortgage
      Loan, and the appraisal and the appraiser both satisfy the applicable
      requirements of Title XI of the Financial Institution Reform, Recovery, and
      Enforcement Act of 1989 and the regulations promulgated thereunder, all as
      in
      effect on the date the Mortgage Loan was originated;

    


    (xxxii)       Insurance.

    


    The
      Mortgaged Property securing each Mortgage Loan is insured by an insurer
      acceptable to Fannie Mae or Freddie Mac against loss by fire and such hazards
      as
      are covered under a standard extended coverage endorsement 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 4.10
      of
      the Servicing Agreement, in an amount which is at least equal to the lesser
      of
      (a) 100% of the insurable value, on a replacement cost basis, of the
      improvements on the related Mortgaged Property, or (b) the greater of (i) either
      (1) the outstanding principal balance of the Mortgage Loan with respect to
      each
      First Lien Mortgage Loan or (2) with respect to each Second Lien Mortgage Loan,
      the sum of the outstanding principal balance of the First Lien on such Mortgage
      Loan and the outstanding principal balance of such Second Lien Mortgage Loan,
      or
      (ii) an amount such that the proceeds of such insurance shall be sufficient
      to
      avoid the application to the Mortgagor or loss payee of any coinsurance clause
      under the policy. If the Mortgaged Property is a condominium unit, it is
      included under the coverage afforded by a blanket policy for the project. If
      the
      improvements on the Mortgaged Property are in an area identified in the Federal
      Register by the Federal Emergency Management Agency as having special flood
      hazards, a flood insurance policy meeting the requirements of the current
      guidelines of the Federal Insurance Administration is in effect with a generally
      acceptable insurance carrier, in an amount representing coverage not less than
      the least of (a) the outstanding principal balance of the Mortgage Loan with
      respect to each First Lien Mortgage Loan or with respect to each Second Lien
      Mortgage Loan, the sum of the outstanding principal balance of the First Lien
      on
      such Mortgage Loan and the outstanding principal balance of such Second Lien
      Mortgage Loan, (b) the full insurable value or (c) the maximum amount of
      insurance which was available under the Flood Disaster Protection Act of 1973,
      as amended. All individual insurance policies contain a standard mortgagee
      clause naming the Seller and its successors and assigns as mortgagee, and all

      and will be in full force and effect and inure to the benefit of the Purchaser
      upon the consummation of the transactions contemplated by this Agreement. The

       Buydown
      Mortgage Loans.

    


    With
      respect to each Mortgage Loan that is a Buydown Mortgage Loan:

    


    
      	
               

            	
              (1)

            	
              On
                or before the date of origination of such Mortgage Loan, the Seller
                and
                the Mortgagor, or the Seller, the Mortgagor and the seller of the
                Mortgaged Property or a third party entered into a Buydown
                Agreement.  The Buydown Agreement provides that the seller of
                the Mortgaged Property (or third party) shall deliver to the Seller
                temporary Buydown Funds in an amount equal to the aggregate undiscounted
                amount of payments that, when added to the amount the Mortgagor on
                such
                Mortgage Loan is obligated to pay on each Due Date in accordance
                with the
                terms of the Buydown Agreement, is equal to the full scheduled Monthly
                Payment due on such Mortgage Loan.  The temporary Buydown Funds
                enable the Mortgagor to qualify for the Buydown Mortgage
                Loan.  The effective interest rate of a Buydown Mortgage Loan if
                less than the interest rate set forth in the related Mortgage Note
                will
                increase within the Buydown Period as provided in the related Buydown
                Agreement so that the effective interest rate will be equal to the
                interest rate as set forth in the related Mortgage Note.  The
                Buydown Mortgage Loan satisfies the requirements of the Underwriting
                Guidelines;

            


    

    


    
      	
               

            	
              (2)

            	
              The
                Mortgage and Mortgage Note reflect the permanent payment terms rather
                than
                the payment terms of the Buydown Agreement.  The Buydown
                Agreement provides for the payment by the Mortgagor of the full amount
                of
                the Monthly Payment on any Due Date that the Buydown Funds are
                available.  The Buydown Funds were not used to reduce the
                original principal balance of the Mortgage Loan or to increase the
                Appraised Value of the Mortgage Property when calculating the
                Loan-to-Value Ratios for purposes of the Agreement and, if the Buydown
                Funds were provided by the Seller and if required under Underwriting
                Guidelines, the terms of the Buydown Agreement were disclosed to
                the
                appraiser of the Mortgaged
                Property;

            


    

    


    
      	
               

            	
              (3)

            	
              The
                Buydown Funds may not be refunded to the Mortgagor unless the Mortgagor
                makes a principal payment for the outstanding balance of the Mortgage
                Loan; and

            


    

    


    
      	
              (4)        
                  

            	
              As
                of the date of origination of the Mortgage Loan, the provisions of
                the
                related Buydown Agreement complied with the Underwriting Guidelines
                (other
                than the exceptions identified for Exception Mortgage Loans on the
                related
                Assignment and Conveyance Agreement) or the Third-Party Underwriting
                Guidelines, as applicable regarding buydown
                agreements;

      creditors’ rights generally or the collectability thereof may be limited due to
      acceleration in connection with a foreclosure); and

    


    
      	 	
              (xlxi)         Prepayment
                Charge Amount and
                Duration.

            


    

    


    Each
      such Prepayment Charge is in an
      amount equal to the maximum amount permitted under applicable law and no
      Mortgage Loan originated on or after October 1, 2002
      provides for the payment of a
      Prepayment Penalty beyond the three-year term following the origination of
      the
      Mortgage Loan. No Mortgage Loan originated prior to such date provides
      for the payment of a Prepayment Penalty beyond the five-year term following
      the
      origination of the Mortgage Loan.

     

    (xlxii)        Valid
      Second Lien.

    


    With
      respect to any Second Lien Mortgage Loan, such Mortgage is a valid, subsisting
      and enforceable Second Lien on the Mortgaged Property, including all buildings
      on the Mortgaged Property and all installations and mechanical, electrical,
      plumbing, heating and air conditioning systems located in or annexed to such
      buildings, and all additions, alterations and replacements made at any time
      with
      respect to the foregoing.  The lien of such Mortgage is subject only
      to:

     

    
      	
              (i)            

            	
              the
                lien of current real property taxes and assessments not yet due and
                payable;

            


    

    


     

    
      	
               

            	
              (ii)

            	
              First
                Lien Mortgage Loan acceptable in accordance with the Underwriting
                Guidelines;

            


    

     

    
      	
               

            	
              (iii)

            	
              covenants,

                lending institutions in accordance with Accepted Servicing Practices
                and
                (i) referred to or otherwise considered in the appraisal and (ii)
                which do
                not adversely affect the Appraised Value;
                and

            


    

     

    
      	
              (iv)          

            	
              other
                matters to which like properties are commonly subject which do not
                materially interfere with the benefits of the security intended to
                be
                provided by the mortgage or the use, enjoyment, value or marketability
                of
                the related Mortgaged Property.

            


    

     

    Any
      security agreement, chattel mortgage or equivalent document related to and
      delivered in connection with such Mortgage Loan establishes and creates a valid,
      subsisting, and enforceable Second Lien and second lien security interest on
      the
      property described therein and the Company has full right to sell and assign
      the
      same to the Purchaser.  With respect to each Second Lien Mortgage
      Loan: (a) the First Lien is in full force and effect, (b) there is no default,
      breach, violation or event of acceleration existing under such First Lien
      Mortgage or the related Mortgage Note, (c) either no consent for the Second
      Lien
      Mortgage Loan is required by the holder of the First Lien or such consent has
      been obtained and is contained in the Mortgage Loan Documents, (d) 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 or
      acceleration under the related First Lien Mortgage Loan and (e) either (A)
      the
      First Lien Mortgage Loan allows or (B) applicable law requires, the mortgagee
      under the Second Lien Mortgage Loan to receive notice of, and affords such
      mortgagee an opportunity to cure any default by payment in full or otherwise
      under the First Lien Mortgage Loan;

    EXHIBIT
      D

    


    Representation
      and Warranties with Respect to the National City Mortgage
      Loans

    


    Except
      for “Mortgage Loans”, which shall mean the National City Mortgage Loans sold by
      the Seller to the Purchaser, all capitalized terms in this Exhibit D shall
      have
      the meanings ascribed to them in the National City Purchase
      Agreement.

     

    As
      to
      each Mortgage Loan, the Company hereby represents and warrants to the Purchaser
      that as of the related Closing Date:

     

    


    (a)  Mortgage
      Loans as Described.  The information set forth in the related
      Mortgage Loan Schedule is complete, true and correct;

     

     

    (b)  Payments
      Current.  All payments required to be made up to the related
      Closing Date for the Mortgage Loan under the terms of the Mortgage Note have
      been made and credited. No payment required under the Mortgage Loan has been
      30
      or more days delinquent at any time in the past 12 months preceding the related
      Closing Date. The first two Monthly Payments shall be made with respect to
      the
      Mortgage Loan within the month in which it is due, all in accordance with the
      terms of the related Mortgage Note;

     

    (c)  No
      Outstanding Charges.  There are no defaults in complying with the
      terms of the Mortgages, and all taxes, governmental assessments, insurance
      premiums, ground rents, leasehold payments, water, sewer and municipal charges,
      leasehold payments or ground rents which previously became due and owing 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 Company 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 under
      the Mortgage Loan, except for interest accruing from the date of the Mortgage
      Note or date of disbursement of the Mortgage Loan proceeds, whichever is
      greater, to the day which precedes by one month the Due Date of the first
      installment of principal and interest;

     

    (d)  Original
      Terms Unmodified.  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 Purchaser and which has been delivered to the Custodian. The
      substance of any such waiver, alteration or modification has been approved
      by
      the issuer of any related PMI Policy and the title insurer, to the extent
      required by the policy, and its terms are reflected on the related Mortgage
      Loan
      Schedule. No instrument of waiver, alteration or modification has been executed,
      and no Mortgagor has been released, in whole or in part, except in connection
      with an assumption agreement approved by the issuer of any related PMI Policy
      and the title insurer, to the extent required by the policy, and which
      assumption agreement is part of the Mortgage Loan File delivered to the
      Custodian and the terms of which are reflected in the related Mortgage Loan
      Schedule;

     

    (e)  No
      Defenses.  The Mortgage Loan is not subject to any right of
      rescission, set-off, counterclaim or defense, including without limitation
      the
      defense of usury, nor will the operation of any of the terms of the Mortgage
      Note or the Mortgage, or the exercise of any right thereunder, render either
      the
      Mortgage Note or the Mortgage unenforceable, in whole or in part, or subject
      to
      any right of rescission, set-off, counterclaim or defense, including without
      limitation the defense of usury, and no such right of rescission, set-off,
      counterclaim or defense has been asserted with respect thereto, and no Mortgagor
      was a debtor in any state or federal bankruptcy or insolvency proceeding at
      the
      time the Mortgage Loan was originated;

     

    (f)  Hazard
      Insurance.  All buildings or other improvements upon the Mortgaged
      Property are 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 Mortgaged Property is located pursuant to insurance policies
      conforming to the requirements of Section 4.10. If the Mortgaged Property is
      in
      an area identified in the Federal Register by the Federal Emergency Management
      Agency as having special flood hazards (and such flood insurance has been made
      available) 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 Section 4.10. All individual insurance
      policies contain a standard mortgagee clause naming the Company and its
      successors and assigns as mortgagee, and all premiums thereon have been paid.
      The Mortgage obligates the 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, the 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 Purchaser upon the consummation of the transactions contemplated by
      this
      Agreement. The Company has not engaged in, and has no knowledge of the
      Mortgagor, any Subservicer or any prior originator or subservicer having engaged
      in, any act or omission which would impair the coverage of any such policy,
      the
      benefits of the endorsement provided for herein, or the validity and binding
      effect of either, including without limitation, no unlawful fee, unlawful
      commission, unlawful 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 Company;

     

    (g)  Compliance
      with Applicable Laws.  Any and all requirements of any federal,
      state or local law including, without limitation, usury, truth-in-lending,
      predatory and abusive lending laws, real estate settlement procedures, consumer
      credit protection, equal credit opportunity or disclosure laws applicable to
      the
      origination and servicing of the Mortgage Loan have been complied with, and
      the
      Company shall maintain in its possession, available for the Purchaser’s
      inspection, and shall deliver to the Purchaser upon demand, evidence of
      compliance with all such requirements;

     

    (h)  No
      Satisfaction of Mortgage.  The Mortgage has not been satisfied,
      canceled, 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. The Company has not waived the
      performance by the Mortgagor of any action, if the Mortgagor’s failure to
      perform such action would cause the Mortgage Loan to be in default, nor has
      the
      Company waived any default resulting from any action or inaction by the
      Mortgagor;

     

    (i)  Location
      and Type of Mortgaged Property.  The Mortgaged Property is a fee
      simple or leasehold property located in the state identified in the related
      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, or an
      individual unit in a planned unit development, provided, however, that any
      condominium project or planned unit development shall conform with the Company’s
      Underwriting Guidelines regarding such dwellings, and no residence or dwelling
      is a mobile home or a manufactured dwelling. No portion of the Mortgaged
      Property is used for commercial purposes;

     

    (j)  Valid
      First Lien.  The Mortgage is a valid, subsisting, enforceable and
      perfected first lien on the Mortgaged Property, including all buildings and
      improvements on the Mortgaged Property, and all additions, alterations and
      replacements made at any time with respect to the foregoing. The lien of the
      Mortgage is subject only to:

     

      (1)                 the
      lien of current real property taxes and assessments not yet due and
      payable;

     

      (2)                 covenants,
      conditions and restrictions, rights of way, easements and other matters of
      the
      public record as of the date of recording acceptable to mortgage lending
      institutions generally and specifically referred to in the lender’s title
      insurance policy delivered to the originator of the Mortgage Loan and (i)
      referred to or to otherwise considered in the appraisal made for the originator
      of the Mortgage Loan or (ii) which do not adversely affect the Appraised Value
      of the Mortgaged Property set forth in such appraisal; and

     

      (3)                 other
      matters to which like properties are commonly subject which do not materially
      interfere with the benefits of the security intended to be provided by the
      mortgage or the use, enjoyment, value or marketability of the related Mortgaged
      Property.

     

    Any
      security agreement, chattel mortgage or equivalent document related to and
      delivered in connection with the Mortgage Loan establishes and creates a valid,
      subsisting and enforceable first lien and first priority security interest
      on
      the property described therein and the Company has full right to sell and assign
      the same to the Purchaser. The Mortgaged Property was not, as of the date of
      origination of the Mortgage Loan, subject to a mortgage, deed of trust, deed
      to
      secured debt or other security instrument creating a lien subordinate to the
      lien of the Mortgage;

     

    (k)  Validity
      of Mortgage Documents.  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 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. No fraud was committed in connection with
      the
      origination of the Mortgage Loan. The Company has reviewed all of the documents
      constituting the Servicing File and has made such inquiries as it deems
      necessary to make and confirm the accuracy of the representations set forth
      herein;

    No
      misrepresentation, negligence, fraud or similar occurrence with respect to
      a
      Mortgage Loan has taken place on the part of any 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.

     

    (l)  Full
      Disbursement of Proceeds.  The Mortgage Loan has been closed and
      the proceeds of the Mortgage Loan have been fully disbursed to or for the
      account of the Mortgagor 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 Mortgage Loan and the recording of the Mortgage were paid, and the Mortgagor
      is not entitled to any refund of any amounts paid or due under the Mortgage
      Note
      or Mortgage;

     

    (m)  Ownership.  The
      Company is the sole owner of record and holder of the Mortgage Loan. The
      Mortgage Loan is not assigned or pledged, and the Company has good and
      marketable title thereto, and has full right to transfer and sell the Mortgage
      Loan therein to the Purchaser free and clear 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 Mortgage Loan pursuant
      to this Agreement;

     

    (n)  Doing
      Business.  All parties which have had any interest in the Mortgage
      Loan, whether as mortgagee, assignee, pledgee or otherwise, are (or, during
      the
      period in which they held and disposed of such interest, were) (1) in compliance
      with any and all applicable doing business’ and licensing requirements of the
      laws of the state wherein the Mortgaged Property is located, and (2) (a)
      organized under the laws of such state, (b) qualified to do business in such
      state, (c) federal savings and loan associations or national banks having
      principal offices in such state, or (d) not doing business in such
      state;

     

    (o)  LTV,
      PMI Policy.  No Mortgage Loan has a LTV equal to or greater than
      95%. The original LTV of the Mortgage Loan either was not more than 80% or
      (i)
      the excess over 75% is and will be insured as to payment defaults by a PMI
      Policy until the LTV of such Mortgage Loan is reduced to 80%, or (ii) is subject
      to an LPMI Policy, which will stay in effect for the life of the Mortgage
      Loan.  All provisions of such PMI 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 action, inaction, or event has occurred and no
      state of facts exists that has, or will result in the exclusion from, denial
      of,
      or defense to coverage. Any Mortgage Loan subject to a PMI Policy obligates
      the
      Mortgagor thereunder to maintain the PMI Policy and to pay all premiums and
      charges in connection therewith; provided, that, with respect to LPMI Loans,
      the
      related Servicer is obligated thereunder to maintain the LPMI Policy and to
      pay
      all premiums and charges in connection therewith..  The Mortgage
      Interest Rate for the Mortgage Loan as set forth on the related Mortgage Loan
      Schedule is net of any such insurance premium;

     

    (p)  Title
      Insurance.  The Mortgage Loan is covered by either (i) an
      attorney’s opinion of title and abstract of title the form and substance of
      which is acceptable to mortgage lending institutions making mortgage loans
      in
      the area where the Mortgaged Property is located or (ii) an ALTA lender’s title
      insurance policy or other generally acceptable form of policy of insurance
      acceptable to Fannie Mae or Freddie Mac, issued by a title insurer acceptable
      to
      Fannie Mae or Freddie Mac and qualified to do business in the jurisdiction
      where
      the Mortgaged Property is located, insuring the Company, its successors and
      assigns, as to the first priority lien of the Mortgage in the original principal
      amount of the Mortgage Loan (or to the extent that a Mortgage Note provides
      for
      negative amortization, the maximum amount of negative amortization in accordance
      with the Mortgage), subject only to the exceptions contained in clauses (1),
      (2)
      and (3) of paragraph (j) of this Section 3.02. Where required by state law
      or
      regulation, the Mortgagor has been given the opportunity to choose the carrier
      of the required mortgage title insurance. Additionally, such lender’s title
      insurance policy affirmatively insures ingress and egress, and against
      encroachments by or upon the Mortgaged Property or any interest therein. The
      Company is the sole insured of such lender’s title insurance policy, and such
      lender’s title insurance policy is in full force and effect and will be in force
      and effect upon the consummation of the transactions contemplated by this
      Agreement. No claims have been made under such lender’s title insurance policy,
      and no prior holder of the Mortgage, including the Company, has done, by act
      or
      omission, anything which would impair the coverage of such lender’s title
      insurance policy 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
      Company;

     

    (q)  No
      Defaults.  There is no default, breach, violation or event of
      acceleration existing under the Mortgage or the Mortgage Note and no event
      which, with the passage of time or with notice and the expiration of any grace
      or cure period, would constitute a default, breach, violation or event of
      acceleration, and neither the Company nor its predecessors have waived any
      default, breach, violation or event of acceleration;

     

    (r)  No
      Mechanics’ Liens.  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;

     

    (s)  Location
      of Improvements; No Encroachments.  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;

     

    (t)  Origination:
      Payment Terms. Such Mortgage Loan was originated by a savings and loan
      association, savings bank, commercial bank, credit union, insurance company,
      or
      similar institution which is supervised and examined by a federal or state
      authority, or by a mortgagee approved by the Secretary of Housing and Urban
      Development pursuant to sections 203 and 211 of the National Housing Act. The
      Mortgage Interest Rate is the interest rate set forth in the Mortgage
      Note.  The Mortgage Note is payable each month in equal monthly
      installments of principal and interest, with interest calculated and payable
      in
      arrears, sufficient to amortize the Mortgage Loan fully by the stated maturity
      date, over an original term of not more than thirty years from commencement
      of
      amortization. There is no negative amortization;

     

    (u)  Customary
      Provisions.  The Mortgage and the related Mortgage Note contains
      customary and enforceable provisions such as to render the rights and remedies
      of the holder thereof adequate for the realization against the Mortgaged
      Property of the benefits of the security provided thereby, including, (i) in
      the
      case of a Mortgage designated as a deed of trust, by trustee’s sale, and (ii)
      otherwise by judicial foreclosure. Upon default by a Mortgagor on a Mortgage
      Loan and foreclosure on, or trustee’s sale of, the Mortgaged Property pursuant
      to the proper procedures, the holder of the Mortgage Loan will be able to
      deliver good and merchantable title to the Mortgaged Property. There is no
      homestead or other exemption available to a Mortgagor which would interfere
      with
      the right to sell the Mortgaged Property at a trustee’s sale or the right to
      foreclose the Mortgage;

     

    (v)  Conformance
      with Underwriting Guidelines.  The Mortgage Loan was underwritten
      in accordance with the Company’s Underwriting Guidelines in effect at the time
      the Mortgage Loan was originated. The Mortgage Loan is in conformity with the
      standards of Freddie Mac or Fannie Mae under one of their respective home
      mortgage purchase programs (except that the principal balance of certain
      Mortgage Loans may have exceeded the limits of Fannie Mae and Freddie Mac)
      and
      the Mortgage Note and Mortgage are on forms acceptable to Freddie Mac or Fannie
      Mae;

     

    (w)  Occupancy

      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
      and fire underwriting certificates, have been made or obtained from the
      appropriate authorities.  Except as otherwise stated on the Mortgage
      Loan Schedule, the Mortgagor represented at the time of origination of the
      Mortgage Loan that the Mortgagor would occupy the Mortgaged Property as the
      Mortgagor’s primary residence;

     

    (x)  No
      Additional Collateral.  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
      referred to in (j) above;

     

    (y)  Deeds
      of Trust.  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 Purchaser to the trustee
      under the deed of trust, except in connection with a trustee’s sale after
      default by the Mortgagor;

     

    (z)  Acceptable
      Investment.  The Company has no knowledge of any circumstances or
      conditions with respect to the Mortgage, the Mortgaged Property, the Mortgagor
      or the Mortgagor’s credit standing that can reasonably be expected to cause
      private institutional investors to regard the Mortgage Loan as an unacceptable
      investment, cause the Mortgage Loan to become delinquent, or adversely affect
      the value or marketability of the Mortgage Loan;

     

    (aa)  Delivery
      of Mortgage Documents.  The Mortgage Note, the Mortgage, the
      Assignment of Mortgage and any other documents required to be delivered for
      the
      Mortgage Loan by the Company under this Agreement as set forth in Exhibit
      C attached hereto have been delivered to the Custodian. The Company is in
      possession of a complete, true and accurate Mortgage File in compliance with
      Exhibit B, except for such documents the originals of which have been
      delivered to the Custodian;

     

    (bb)  Condominiums/Planned
      Unit Developments.  If the dwelling on the Mortgaged Property is a
      condominium unit or a planned unit development (other than a de minimus planned
      unit development) such condominium or planned unit development project meets
      Fannie Mae and Freddie Mac eligibility requirements.

     

    (cc)  Transfer

      form and is acceptable for recording under the laws of the jurisdiction in
      which
      the Mortgaged Property is located;

     

    (dd)  Due
      on
      Sale.  The Mortgage contains an enforceable provision 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 Mortgagor thereunder;

     

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

     

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

      compliance with all applicable laws and regulations. The Mortgage Loan has
      been
      serviced by the Company and any predecessor servicer in accordance with the
      terms of the Mortgage Note.  With respect to escrow deposits and
      Escrow Payments, all such payments are in the possession of the Company 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 Company have been capitalized under the
      Mortgage or the Mortgage Note and no such escrow deposits or Escrow Payments
      are
      being held by the Company for any work on a Mortgaged Property which has not
      been completed;

     

    (hh)       Appraisal.  The
      Mortgage File contains an appraisal of the related Mortgage Property signed
      prior to the approval of the Mortgage Loan application by a qualified appraiser,
      duly appointed by the Company, 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 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 Mortgage Loan was originated;

     

    (ii)       Soldiers’

      amended;

     

    (jj)       Environmental
      Matters.  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. To the best of the Company’s
      knowledge, there is no pending action or proceeding directly involving any
      Mortgaged Property of which the Company is aware in which compliance with any
      environmental law, rule or regulation is an issue; and to the best of the
      Company’s knowledge, nothing further remains to be done to satisfy in full all
      requirements of each such law, rule or regulation consisting a prerequisite
      to
      use and enjoyment of said property;

     

    (kk)  Insurance.  The
      Company has caused or will cause to be performed any and all acts required
      to

      notifications of insurers, assignments of policies or interests therein, and
      establishments of coinsured, joint loss payee and mortgagee rights in favor
      of
      the Purchaser;  No action, inaction, or event has occurred and no
      state of fact exists or has existed that has resulted or will result in the
      exclusion from, denial of, or defense to coverage under any applicable pool
      insurance policy, special hazard insurance policy, PMI 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 Company or any designee of the Company
      or

      had a
      financial interest at the time of placement of such insurance;

      Mortgage (other than the assignment to the Purchaser) have been recorded in
      the
      appropriate jurisdictions wherein such recordation is necessary to perfect
      the
      lien thereof as against creditors of the Company, or is in the process of being
      recorded;

     

    (uu)  Leaseholds.  If
      the Mortgage Loan is secured by a long-term residential lease, (1) the lessor

    (hhh)  No
      Mortgage Loan is secured by real property or secured  by a
      manufactured home located in the state of Georgia unless (x) such Mortgage
      Loan
      was originated prior to October 1, 2002 or after March 6, 2003, or (y) the
      property securing the Mortgage Loan is not, nor will be, occupied by the
      Mortgagor as the Mortgagor's principal dwelling.  No Mortgage Loan is
      a “High Cost Home Loan” as defined in the Georgia Fair Lending Act, as amended
      (the “Georgia Act”).   Each Mortgage Loan that is a “Home Loan”
under the Georgia Act complies with all applicable provisions of the Georgia
      Act. No Mortgage Loan secured by owner occupied real property or an owner
      occupied manufactured home located in the State of Georgia was originated (or
      modified) on or after October 1, 2002 through and including March 6, 2003,
      if
      applicable to the Company or any subsequent Owner;

     

    (iii)  If
      applicable to the Company or any subsequent Owner, n o Mortgagor was encouraged
      or required to select a Mortgage Loan product offered by the Mortgage Loan's
      originator which is a higher cost product designed for less creditworthy
      borrowers, unless at the time of the Mortgage Loan's origination, such Mortgagor
      did not qualify taking into account credit history and debt to income ratios
      for
      a lower cost credit product then offered by the Mortgage Loan's originator
      or
      any affiliate of the Mortgage Loan's originator.  If, at the time of
      loan application, the Mortgagor may have qualified for a for a lower cost credit
      product then offered by any mortgage lending affiliate of the Mortgage Loan's
      originator, the Mortgage Loan's originator referred the Mortgagor's application
      to such affiliate for underwriting consideration;

     

    (jjj)  The
      methodology used in underwriting the extension of credit for each Mortgage
      Loan
      employs objective mathematical principles which relate the Mortgagor's income,
      assets and liabilities to the proposed payment and such underwriting methodology
      does not rely on the extent of the Mortgagor's equity in the collateral as
      the
      principal determining factor in approving such credit extension.  Such
      underwriting methodology confirmed that at the time of origination
      (application/approval) the Mortgagor had a reasonable ability to make timely
      payments on the Mortgage Loan; 

     

    (kkk)  All
      fees
      and charges (including finance charges) and whether or not financed, assessed,
      collected or to be collected in connection with the origination and servicing
      of
      each Mortgage Loan have been disclosed in writing to the Mortgagor in accordance
      with applicable state and federal law and regulation;

     

    (lll)  With
      respect to each Mortgage Loan, neither the related Mortgage nor the related
      Mortgage Note requires the Mortgagor to submit to arbitration to resolve any
      dispute arising out of or relating in any way to the Mortgage Loan
      transaction;

     

    (mmm)    With
      respect to any Mortgage Loan for which a mortgage loan application was submitted
      by the Mortgagor after April 1, 2004, no such Mortgage Loan secured by a
      Mortgage Property located in the State of Illinois is in violation of the
      provisions of the Illinois Interest Act, including Section 4.1a which provides
      that no such Mortgage Loan with a Mortgage Interest Rate in excess of 8.0%
      per
      annum has lender-imposed fees (or other charges) in excess of 3.0% of the
      original principal balance of the Mortgage Loan; and

     

    (nnn)  No
      Mortgage Loan originated on or after November 7, 2004 secured by a Mortgaged
      Property located in the State of Massachusetts is a Refinanced Mortgage
      Loan.

    Ladies
      and Gentlemen:

     

    In
      connection with the transfer by ________________ (the “Transferor”) to
      ________________ (the “Transferee”) of the captioned mortgage pass-through
      certificates (the “Certificates”), the Transferor hereby certifies as
      follows:

     

    Neither
      the Transferor nor anyone acting on its behalf has (a) offered, pledged, sold,
      disposed of or otherwise transferred any Certificate, any interest in any
      Certificate or any other similar security to any person in any manner, (b)
      has
      solicited any offer to buy or to accept a pledge, disposition or other transfer
      of any Certificate, any interest in any Certificate or any other similar
      security from any person in any manner, (c) has otherwise approached or
      negotiated with respect to any Certificate, any interest in any Certificate
      or
      any other similar security with any person in any manner, (d) has made any
      general solicitation by means of general advertising or in any other manner,
      (e)
      has taken any other action, that (in the case of each of subclauses (a) through
      (e) above) would constitute a distribution of the Certificates under the
      Securities Act of 1933, as amended (the “1933 Act”), or would render the
      disposition of any Certificate a violation of Section 5 of the 1933 Act or
      any
      state securities law or would require registration or qualification pursuant
      thereto. The Transferor will not act, nor has it authorized or will it authorize
      any person to act, in any manner set forth in the foregoing sentence with
      respect to any Certificate. The Transferor will not sell or otherwise transfer
      any of the Certificates, except in compliance with the provisions of that

      administrator and master servicer, Citibank, N.A. as paying agent, certificate
      registrar and authenticating agent and U.S. Bank National Association as Trustee

      Agreement the Certificates were issued.

                the cost of such securities to the Transferee and did not include
                any of
                the securities referred to in the preceding paragraph. Further, in
                determining such aggregate amount, the Transferee may have included
                securities owned by subsidiaries of the Transferee, but only if such
                subsidiaries are consolidated with the Transferee in its financial
                statements prepared in accordance with generally accepted accounting
                principles and if the investments of such subsidiaries are managed
                under
                the Transferee's direction. However, such securities were not included
                if
                the Transferee is a majority-owned, consolidated subsidiary of another
                enterprise and the Transferee is not itself a reporting company under
                the
                Securities Exchange Act of 1934.

            
	 	 	 
	 	
              5.

            	
              The
                Transferee acknowledges that it is familiar with Rule 144A and understands
                that the Transferor and other parties related to the Certificates
                are
                relying and will continue to rely on the statements made herein because
                one or more sales to the Transferee may be in reliance on Rule
                144A.

            


    

    


    
      	
              ___

              Yes

               

            	
              ___

              No

               

            	
              Will
                the Transferee be purchasing the Certificates only for the Transferee's
                own account?

               

            


    

    


    
      	 	
              6.

            	
              If
                the answer to the foregoing question is “no”, the Transferee agrees that,
                in connection with any purchase of securities sold to the Transferee
                for
                the account of a third party (including any separate account) in
                reliance
                on Rule 144A, the Transferee will only purchase for the account of
                a third
                party that at the time is a “qualified institutional buyer” within the
                meaning of Rule 144A. In addition, the Transferee agrees that the
                Transferee will not purchase securities for a third party unless
                the
                Transferee has obtained a current representation letter from such
                third
                party or taken other appropriate steps contemplated by Rule 144A
                to
                conclude that such third party independently meets the definition
                of
                “qualified institutional buyer” set forth in Rule 144A.

            
	 	 	 
	 	
              7.

            	
              The
                Transferee will notify each of the parties to which this certification
                is
                made of any changes in the information and conclusions herein. Until
                such
                notice is given, the Transferee's purchase of the Certificates will
                constitute a reaffirmation of this certification as of the date of
                such
                purchase. In addition, if the Transferee is a bank or savings and
                loan as
                provided above, the Transferee agrees that it will furnish to such
                parties
                updated annual financial statements promptly after they become
                available.

    QUALIFIED
      INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A

     

    [For

    The
      undersigned hereby certifies as follows to [name of Transferor] (the
“Transferor”) and U.S. Bank National Association, as Trustee, with respect to
      the mortgage pass- through certificates (the “Certificates”) described in the
      Transferee Certificate to which this certification relates and to which this
      certification is an Annex:

     

    1.  As
      indicated below, the undersigned is the President, Chief Financial Officer
      or

“Transferee”) or, if the Transferee is a “qualified institutional buyer” as that
      term is defined in Rule 144A under the Securities Act of 1933 (“Rule 144A”)
      because the Transferee is part of a Family of Investment Companies (as defined
      below), is such an officer of the investment adviser (the
“Adviser”).

     

    2.  In
      connection with purchases by the Transferee, the Transferee is a “qualified
      institutional buyer” as defined in Rule 144A because (i) the Transferee is an
      investment company registered under the Investment Company Act of 1940, and
      (ii)
      as marked below, the Transferee alone, or the Transferee's Family of Investment
      Companies, owned at least $100,000,000 in securities (other than the excluded
      securities referred to below) as of the end of the Transferee's most recent
      fiscal year. For purposes of determining the amount of securities owned by
      the
      Transferee or the Transferee's Family of Investment Companies, the cost of
      such
      securities was used.

      Transferee owned $___________________ in securities (other than the excluded
      securities referred to below) as of the end of the Transferee's most recent

      144A).

     

    ____
      The
      Transferee is part of a Family of Investment Companies which owned in the
      aggregate $______________ in securities (other than the excluded securities
      referred to below) as of the end of the Transferee's most recent fiscal year
      (such amount being calculated in accordance with Rule 144A).

     

    3.  The
      term
“FAMILY OF INVESTMENT COMPANIES” as used herein means two or more registered
      investment companies (or series thereof) that have the same investment adviser
      or investment advisers that are affiliated (by virtue of being majority owned
      subsidiaries of the same parent or because one investment adviser is a majority
      owned subsidiary of the other).

     

    4.  The
      term
“SECURITIES” as used herein does not include (i) securities of issuers that are
      affiliated with the Transferee or are part of the Transferee's Family of
      Investment Companies, (ii) securities issued or guaranteed by the U.S. or any
      instrumentality thereof, (iii) bank deposit notes and certificates of deposit,
      (iv) loan participations, (v) repurchase agreements, (vi) securities owned

      subject to a repurchase agreement and (vii) currency, interest rate and
      commodity swaps.

     

    5.  The
      Transferee is familiar with Rule 144A and understands that the parties to which
      this certification is being made are relying and will continue to rely on the
      statements made herein because one or more sales to the Transferee will be
      in
      reliance on Rule 144A. In addition, the Transferee will only purchase for the
      Transferee's own account.

     

    6.  The
      undersigned will notify the parties to which this certification is made of
      any
      changes in the information and conclusions herein. Until such notice, the
      Transferee's purchase of the Certificates will constitute a reaffirmation of
      this certification by the undersigned as of the date of such
      purchase.

    EXHIBIT
      F-2

     

    The
      undersigned, being first duly sworn, deposes and says as follows:

     

    1.  The
      undersigned is an officer of, the proposed Transferee of an Ownership Interest
      in a Residual Certificate (the “Certificate”) issued pursuant to the
      Pooling and Servicing Agreement dated as of February 1, 2007 (the
“Agreement”), among Citigroup Mortgage Loan Trust Inc., as depositor (the
“Depositor”), CitiMortgage, Inc., as master servicer and trust
      administrator (the “Master Servicer”), Citibank, N.A., as paying agent,
      certificate registrar and authenticating agent (the “Paying Agent”) and
      U.S. Bank National Association, as trustee (the
“Trustee”).  Capitalized terms used, but not defined herein or
      in Exhibit 1 hereto, shall have the meanings ascribed to such terms in the
      Agreement.  The Transferee has authorized the undersigned to make this
      affidavit on behalf of the Transferee for the benefit of the Depositor and
      the
      Trustee.

     

    2.  The
      Transferee is, as of the date hereof, and will be, as of the date of the
      Transfer, a Permitted Transferee.  The Transferee is acquiring its
      Ownership Interest in the Certificate for its own account.  The
      Transferee has no knowledge that any such affidavit is false.

     

    3.  The
      Transferee has been advised of, and understands that (i) a tax will be
      imposed on Transfers of the Certificate to Persons that are not Permitted
      Transferees; (ii) such tax will be imposed on the transferor, or, if such
      Transfer is through an agent (which includes a broker, nominee or middleman)
      for
      a Person that is not a Permitted Transferee, on the agent; and (iii) the
      Person otherwise liable for the tax shall be relieved of liability for the
      tax
      if the subsequent Transferee furnished to such Person an affidavit that such
      subsequent Transferee is a Permitted Transferee and, at the time of Transfer,
      such Person does not have actual knowledge that the affidavit is
      false.

     

    4.  The
      Transferee has been advised of, and understands that a tax will be imposed
      on a
“pass-through entity” holding the Certificate if at any time during the taxable
      year of the pass-through entity a Person that is not a Permitted Transferee
      is
      the record holder of an interest in such entity.  The Transferee
      understands that such tax will not be imposed for any period with respect to
      which the record holder furnishes to the pass-through entity an affidavit that
      such record holder is a Permitted Transferee and the pass-through entity does
      not have actual knowledge that such affidavit is false.  (For this
      purpose, a “pass-through entity” includes a regulated investment company, a real
      estate investment trust or common trust fund, a partnership, trust or estate,
      and certain cooperatives and, except as may be provided in Treasury Regulations,
      persons holding interests in pass-through entities as a nominee for another
      Person.)

     

    5.  The
      Transferee has reviewed the provisions of Section 5.02(d) of the Agreement
      and understands the legal consequences of the acquisition of an Ownership
      Interest in the Certificate including, without limitation, the restrictions
      on
      subsequent Transfers and the provisions regarding voiding the Transfer and
      mandatory sales.  The Transferee expressly agrees to be bound by and
      to abide by the provisions of Section 5.02(d) of the Agreement and the
      restrictions noted on the face of the Certificate.  The Transferee
      understands and agrees that any breach of any of the representations included
      herein shall render the Transfer to the Transferee contemplated hereby null
      and
      void.

     

    6.  The
      Transferee agrees to require a Transfer Affidavit from any Person to whom the
      Transferee attempts to Transfer its Ownership Interest in the Certificate,
      and
      in connection with any Transfer by a Person for whom the Transferee is acting
      as
      nominee, trustee or agent, and the Transferee will not Transfer its Ownership
      Interest or cause any Ownership Interest to be Transferred to any Person that
      the Transferee knows is not a Permitted Transferee.  In connection
      with any such Transfer by the Transferee, the Transferee agrees to deliver
      to
      the Trustee a certificate substantially in the form set forth as Exhibit L
      to the Agreement (a “Transferor Certificate”) to the effect that such
      Transferee has no actual knowledge that the Person to which the Transfer is
      to
      be made is not a Permitted Transferee.

     

    7.  The
      Transferee has historically paid its debts as they have come due, intends to
      pay
      its debts as they come due in the future, and understands that the taxes payable
      with respect to the Certificate may exceed the cash flow with respect thereto
      in
      some or all periods and intends to pay such taxes as they become
      due.  The Transferee does not have the intention to impede the
      assessment or collection of any tax legally required to be paid with respect
      to
      the Certificate.

     

    8.  The
      Transferee’s taxpayer identification number is ___________.

     

    9.  The
      Transferee is a U.S. Person as defined in Code
      Section 7701(a)(30).

     

    10.  The
      Transferee is aware that the Certificate may be a “noneconomic residual
      interest” within the meaning of proposed Treasury regulations promulgated
      pursuant to the Code and that the transferor of a noneconomic residual interest
      will remain liable for any taxes due with respect to the income on such residual
      interest, unless no significant purpose of the transfer was to impede the
      assessment or collection of tax.

     

    11.  The
      Transferee will not cause income from the Certificate to be attributable to
      a
      foreign permanent establishment or fixed base, within the meaning of an
      applicable income tax treaty, of the Transferee or any other U.S.
      person.

     

    12.  Check
      one
      of the following:

    [  
      ]  The present value of the anticipated tax liabilities associated
      with holding the Certificate, as applicable, does not exceed the sum
      of:

     

    
      	 	
              (i)

               

            	
              the
                present value of any consideration given to the Transferee to acquire
                such
                Certificate;

               

            
	 	
              (ii)

               

            	
              the
                present value of the expected future distributions on such Certificate;
                and

               

            
	 	
              (iii)

               

            	
              the
                present value of the anticipated tax savings associated with holding
                such
                Certificate as the related REMIC generates losses.

               

            


    

    For
      purposes of this calculation, (i) the Transferee is assumed to pay tax at the
      highest rate currently specified in Section 11(b) of the Code (but the tax
      rate
      in Section 55(b)(1)(B) of the Code may be used in lieu of the highest rate
      specified in Section 11(b) of the Code if the Transferee has been subject to
      the
      alternative minimum tax under Section 55 of the Code in the preceding two years
      and will compute its taxable income in the current taxable year using the
      alternative minimum tax rate) and (ii) present values are computed using a
      discount rate equal to the short-term Federal rate prescribed by Section 1274(d)
      of the Code for the month of the transfer and the compounding period used by
      the
      Transferee.

     

    [ 
      ]  The transfer of the Certificate complies with U.S. Treasury
      Regulations Sections 1.860E-1(c)(5) and (6) and, accordingly,

     

    
      	 	
              (i)

               

            	
              the
                Transferee is an “eligible corporation,” as defined in U.S. Treasury
                Regulations Section 1.860E-1(c)(6)(i), as to which income from the
                Certificate will only be taxed in the United States;

               

            
	 	
              (ii)

               

            	
              at
                the time of the transfer, and at the close of the Transferee’s two fiscal
                years preceding the year of the transfer, the Transferee had gross
                assets
                for financial reporting purposes (excluding any obligation of a person
                related to the Transferee within the meaning of U.S. Treasury Regulations
                Section 1.860E-1(c)(6)(ii)) in excess of $100 million and net assets
                in
                excess of $10 million;

              the
                Transferee will transfer the Certificate only to another “eligible
                corporation,” as defined in U.S. Treasury Regulations Section
                1.860E-1(c)(6)(i), in a transaction that satisfies the requirements
                of
                Sections 1.860E-1(c)(4)(i), (ii) and (iii) and Section 1.860E-1(c)(5)
                of
                the U.S. Treasury Regulations; and

               

            
	 	
              (iv)

               

            	
              the
                Transferee determined the consideration paid to it to acquire the
                Certificate based on reasonable market assumptions (including, but
                not
                limited to, borrowing and investment rates, prepayment and loss
                assumptions, expense and reinvestment assumptions, tax rates and
                other
                factors specific to the Transferee) that it has determined in good
                faith.

               

            


    

    [   
      ]  None of the above.

     

    13.  The
      Transferee is not an employee benefit plan that is subject to Title I of ERISA
      or a plan that is subject to Section 4975 of the Code or a plan subject to
      any Federal, state or local law that is substantially similar to Title I of
      ERISA or Section 4975 of the Code, and the Transferee is not acting on behalf
      of
      or investing plan assets of such a plan.

     

    IN
      WITNESS WHEREOF, the Transferee has caused this instrument to be executed on
      its
      behalf, pursuant to authority of its Board of Directors, by its duly authorized
      officer and its corporate seal to be hereunto affixed, duly attested, this

    __________________________,
      being duly sworn, deposes, represents and warrants as follows:

     

    1.  I
      am a
      ____________________ of ____________________________ (the “Owner”), a
      corporation duly organized and existing under the laws of ______________, on
      behalf of whom I make this affidavit.

     

    2.  The
      Owner
      is not transferring the Class R Certificates (the “Residual Certificates”) to
      impede the assessment or collection of any tax.

     

    3.  The
      Owner
      has no actual knowledge that the Person that is the proposed transferee (the
      “Purchaser”) of the Residual Certificates: (i) has insufficient assets to pay
      any taxes owed by such proposed transferee as holder of the Residual
      Certificates; (ii) may become insolvent or subject to a bankruptcy proceeding
      for so long as the Residual Certificates remain outstanding and (iii) is not
      a
      Permitted Transferee.

     

    4.  The
      Owner
      understands that the Purchaser has delivered to the Trustee a transfer affidavit
      and agreement in the form attached to the Pooling and Servicing Agreement as
      Exhibit F-2.  The Owner does not know or believe that any
      representation contained therein is false.

     

    5.  At
      the
      time of transfer, the Owner has conducted a reasonable investigation of the
      financial condition of the Purchaser as contemplated by Treasury Regulations
      Section 1.860E-1(c)(4)(i) and, as a result of that investigation, the Owner
      has
      determined that the Purchaser has historically paid its debts as they became
      due
      and has found no significant evidence to indicate that the Purchaser will not
      continue to pay its debts as they become due in the future. The Owner
      understands that the transfer of a Residual Certificate may not be respected
      for
      United States income tax purposes (and the Owner may continue to be liable
      for
      United States income taxes associated therewith) unless the Owner has conducted
      such an investigation.

     

    6.  Capitalized
      terms not otherwise defined herein shall have the meanings ascribed to them
      in
      the Pooling and Servicing Agreement.

     

    IN
      WITNESS WHEREOF, the Owner has caused this instrument to be executed on its
      behalf, pursuant to the authority of its Board of Directors, by its [Vice]
      President, attested by its [Assistant] Secretary, this ____ day of ___________,
      20__.

    I,
      [identify the certifying individual], acting of [CitiMortgage, Inc.
      (“CitiMortgage”)], certify to Citigroup Mortgage Loan Trust, Inc. (the
“Depositor”), the Trust Administrator and their respective officers, directors
      and affiliates, and with the knowledge and intent that they will rely upon
      this
      certification, that:

     

    1.           I
      have reviewed the information provided to the Trust Administrator by the Master
      Servicer pursuant to the Servicing Agreement and included in the annual report
      on Form 10-K for the fiscal year [___], and all reports on Form 10-D required
      to
      be filed in respect of the period covered by such Form 10-K of the Depositor
      relating to the above-referenced trust (the “Exchange Act periodic reports”)
      (the “Servicing Information”);

     

    2.           Based
      on my knowledge, the Servicing Information in the Exchange Act periodic reports,
      taken as a whole, does not contain any untrue statement of a material fact
      or
      omit to state a material fact necessary to make the statements made, in light
      of
      the circumstances under which such statements were made, not misleading as
      of
      the last day of the period covered by that annual report;

     

    3.           Based
      on my knowledge, the Servicing Information required to be provided to the Trust
      Administrator by the Master Servicer has been provided as required under the
      Pooling and Servicing Agreement;

     

    4.           I
      am responsible for reviewing the activities performed by the Master Servicer
      under the Pooling and Servicing Agreement and based upon the review required
      under the Pooling and Servicing Agreement, and except as disclosed to the
      Depositor and the Trust Administrator, the Master Servicer has fulfilled in
      all
      material respects its obligations under the Pooling and Servicing Agreement;
      and

     

    5.           I
      have disclosed to the Master Servicer’s certified public accountants and the
      Depositor all significant deficiencies relating to the Master Servicer’s
      compliance with the Servicing Criteria as set forth in the Pooling and Servicing
      Agreement.
