    RECITALS
    WHEREAS,
      ▇▇▇▇▇▇ Brothers Bank, FSB (the “Bank”) acquired certain conventional,
      residential, negative amortization, first lien mortgage loans (the “Mortgage
      Loans” as identified on Exhibit D) from the Servicer, which Mortgage Loans were

    WHEREAS,
      the Seller desires that the Servicer continue to service the Mortgage Loans,
      and
      the Servicer has agreed to do so, subject to the rights of the Seller (with
      the
      consent of the Master Servicer) to terminate the rights and obligations of
      the
      Servicer hereunder at any time without cause and to the other conditions set
      forth herein.
    WHEREAS,

      and
      until the Transfer Date.
    WHEREAS,
      the Seller and Servicer agree that on the Transfer Date the Servicer shall
      no
      longer service the Mortgage Loans and shall transfer servicing of the Mortgage
      Loans to the successor servicer designated by the Seller herein.
    WHEREAS,
      the Master Servicer and any successor master servicer shall be obligated, among
      other things, to supervise the servicing of the Mortgage Loans on behalf of
      the
      Trustee, and shall have the right under the conditions specified herein to
      terminate for cause the rights and obligations of the Servicer under this
      Agreement.
    WHEREAS,
      the Seller and the Servicer intend that each of the Master Servicer and the
      Trustee is an intended third party beneficiary of this Agreement.

      and
      for other good and valuable consideration, the receipt and adequacy of which
      are
      hereby acknowledged, the Seller and the Servicer hereby agree as
      follows:
    AGREEMENT
    1. Definitions.
      Capitalized terms used and not defined in this Agreement, including Exhibit
      A
      hereto and any provisions of the Flow Agreement incorporated by reference herein
      (regardless of whether such terms are defined in the Flow Agreement or Purchase
      Agreement), shall have the meanings ascribed to such terms in the Trust
      Agreement.
    2. Custodianship.
      The
      parties hereto acknowledge that U.S. Bank Trust, National Association will
      act
      as custodian of the Serviced Mortgage Files for the Trustee pursuant to a
      Custodial Agreement, dated May 1, 2007, between U.S. Bank National Association
      and the Trustee.
    3. Servicing
      Transfer Date.
      The
      Servicer agrees, with respect to the Mortgage Loans, to perform and observe
      the
      duties, responsibilities and obligations that are to be performed and observed
      under the provisions of the Flow Agreement, except as otherwise provided herein
      and on Exhibit A hereto, and that the provisions of the Flow Agreement, as
      so
      modified, are and shall be a part of this Agreement to the same extent as if
      set
      forth herein in full. On the Transfer Date (i.e., the date selected by mutual
      agreement of the parties for the transfer of the servicing of the Mortgage
      Loans), the Servicer shall transfer all servicing of the Mortgage Loans in
      accordance with the Flow Agreement and the Purchase Agreement to the successor
      servicer designated by the Seller.

      include principal due after May 1, 2007 (the “Trust Cut-off Date”) plus
      interest, at the Mortgage Loan Remittance Rate collected during the related
      Due
      Period exclusive of any portion thereof allocable to a period prior to the
      Trust
      Cut-off Date, with the adjustments specified in clause (b) of Section 3.01

      Servicing; Termination of Servicer.
      The
      Servicer, including any successor servicer hereunder, shall be subject to the
      supervision of the Master Servicer, which Master Servicer shall be obligated
      to
      ensure that the Servicer services the Mortgage Loans in accordance with the
      provisions of this Agreement. The Master Servicer, acting on behalf of the
      Trustee and the GPMF 2007-AR3 Trust Fund (the “Trust Fund”) created pursuant to
      the Trust Agreement, shall have the same rights as the Seller under the Flow
      Agreement to enforce the obligations of the Servicer under such Flow Agreement
      and the term “Purchaser” as used in the Flow Agreement in connection with any
      rights of the Purchaser shall refer to the Trust Fund or, as the context
      requires, the Master Servicer acting in its capacity as agent for the Trust
      Fund, except as otherwise specified in Exhibit A hereto. The Master Servicer
      shall be entitled to terminate the rights and obligations of the Servicer under
      this Agreement upon the failure of the Servicer to perform any of its
      obligations under this Agreement, which failure results in an Event of Default
      as provided in Article XI of the Flow Agreement. Notwithstanding anything herein
      to the contrary, in no event shall the Master Servicer assume any of the
      obligations of the Seller under the Flow Agreement and, in connection with
      the
      performance of the Master Servicer’s duties hereunder, the parties and other
      signatories hereto agree that the Master Servicer shall be entitled to all
      of
      the rights, protections and limitations of liability afforded to the Master
      Servicer under the Trust Agreement.

      and issuance of the Certificates issued pursuant thereto.

    9. Counterparts.
      This
      Agreement may be executed in any number of counterparts, each of which when

    10. NIMS
      Insurer.
      In
      addition to the terms and conditions set forth in this Agreement, any and all
      rights of the Master Servicer and Trustee to receive notices from the Servicer
      pursuant to this Agreement shall hereby be equally granted to the NIMS Insurer.
      The Master Servicer or the Trustee shall notify the Servicer in writing of
      the
      name and address of the NIMS insurer and the name and telephone number of the
      appropriate contact employee of the NIMS Insurer. For any and all obligations
      of
      the Servicer to obtain consent from the Master Servicer and the Trustee pursuant
      to this Agreement, the Servicer must also obtain such consent from the NIMS
      Insurer. Notwithstanding any other provision in this Agreement, the Trust Fund
      shall hold harmless and indemnify the Servicer for any failure of the NIMS
      Insurer to comply with the provisions of this Agreement. Notwithstanding any
      provision herein to the contrary, the parties to this Agreement agree that

      appropriate, in furtherance of the intent of such parties as set forth herein,
      that the NIMS Insurer receive the benefit of the provisions of this Agreement
      as
      an intended third party beneficiary of this Agreement to the extent of such
      provisions. The Servicer shall have the same obligations to the NIMS Insurer
      as
      if it was a party to this Agreement, and the NIMS Insurer shall have the same
      rights and remedies to enforce the provisions of this Agreement as if it was
      a
      party to this Agreement. The parties hereto agree to cooperate in good faith
      to
      amend this Agreement in accordance with the terms hereof to include such other
      provisions as may be reasonably requested by the NIMS Insurer. Notwithstanding
      the foregoing, all rights of the NIMS Insurer set forth in this Agreement shall
      exist only so long as the NIM Securities issued pursuant to the NIMS Transaction
      remain outstanding or the NIMS Insurer is owed amounts in respect of its
      guarantee of payment on such NIM Securities.
    -4-
        “NIM
      Security” shall mean any net interest margin security issued by an owner trust
      or special purpose entity that is holding all rights, title and interest in
      and
      to the Class X or Class AP Certificates issued by the Trust Fund. 
    “NIMS
      Insurer” shall mean collectively, any insurance companies issuing a financial
      guaranty insurance policy covering certain payments to be made on NIM Securities
      pursuant to a NIMS Transaction. 
    “NIMS
      Transaction” shall mean any transaction in which NIM Securities are secured, in
      part, by the payments on the Class X or Class AP Certificates issued by the
      Trust Fund.
    11. Distressed
      Mortgage Loans.
      The
      NIMS Insurer may, at its option, purchase a Distressed Mortgage Loan. Any such
      purchase shall be accomplished by: (A) remittance to the Master Servicer of
      the
      Purchase Price (as defined in the Trust Agreement) for the Distressed Mortgage
      Loan for deposit into the Collection Account established by the Master Servicer
      pursuant to the Trust Agreement, and (B) the NIMS Insurer’s (i) acknowledgment
      and agreement to retain Servicer, as the servicer for any such purchased
      Distressed Mortgage Loan, to service such Distressed Mortgage Loan pursuant
      to
      the provisions of the Flow Agreement, and (ii) assumption, for the benefit
      of
      the Servicer, the rights and obligations of the Trust Fund as owner of such
      purchased Distressed Mortgage Loans pursuant to the Flow Agreement. The Trustee
      and the Servicer shall immediately effectuate the conveyance of the purchased
      Distressed Mortgage Loans to the NIMS Insurer exercising the purchase option,
      including prompt delivery of the Servicing File and all related documentation
      to
      the applicable NIMS Insurer. A Distressed Mortgage Loan is as of any
      Determination Date a Mortgage Loan that is delinquent in payment for a period
      of
      ninety (90) days or more, without giving effect to any grace period permitted
      by
      the related Mortgage Loan, or for which the Servicer or Trustee has accepted
      a
      deed in lieu of foreclosure.

                relating to the Mortgage Loans and not relating to the servicing

      or expend fees or sums of money in addition to those specifically set forth
      in

| (i) | adding
                the following paragraph as the third paragraph of such
                Section: | 
Notwithstanding
      anything to the contrary contained in this Section 2.17, in connection with
      a
      foreclosure or acceptance of a deed in lieu of foreclosure, in the event the
      Seller has reasonable cause to believe that a Mortgaged Property is contaminated
      by hazardous or toxic substances or wastes, or if the Trustee or the Master
      Servicer otherwise requests, an environmental inspection or review of such
      Mortgaged Property to be conducted by a qualified inspector shall be arranged
      by
      the Seller. Upon completion of the inspection, the Seller shall provide the
      Trustee and the Master Servicer with a written report of such environmental
      inspection. In the event that the environmental inspection report indicates
      that
      the Mortgaged Property is contaminated by hazardous or toxic substances or
      wastes, the Seller shall not proceed with foreclosure or acceptance of a deed
      in
      lieu of foreclosure. In the event that the environmental inspection report
      is
      inconclusive as to the whether or not the Mortgaged Property is contaminated
      by
      hazardous or toxic substances or wastes, the Seller shall not, without the
      prior
      approval of the Trustee, proceed with foreclosure or acceptance of a deed in
      lieu of foreclosure. In such instance, the Trustee shall be deemed to have
      approved such foreclosure or acceptance of a deed in lieu of foreclosure unless
      the Trustee notifies the Seller in writing, within two (2) Business Days after
      its receipt of written notice of the proposed foreclosure or deed in lieu of
      foreclosure from the Seller, that it disapproves of the related foreclosure
      or
      acceptance of a deed in lieu of foreclosure. The Seller shall be reimbursed
      for
      all Servicing Advances made pursuant to this paragraph with respect to the
      related Mortgaged Property from the Custodial Account.
    (ii) by
      replacing the existing third paragraph of such section (before the amendment
      made by (i) above) by the following paragraph:
    The
      Seller shall use its Best Efforts to dispose of the REO Property as soon as
      possible and shall sell such REO Property in any event within three years after
      title has been taken to such REO Property, unless (a) a REMIC election has
      not
      been made with respect to the arrangement under which the Mortgage Loans and
      the
      REO Property are held, and (b) the Seller determines, and gives an appropriate
      notice to the Master Servicer to such effect, that a longer period is necessary
      for the orderly liquidation of such REO Property. If a period longer than three
      years is permitted under the foregoing sentence and is necessary to sell any
      REO
      Property, (i) the Seller shall report monthly to the Master Servicer as to
      the
      progress being made in selling such REO Property and (ii) if, with the written
      consent of the Trustee, a purchase money mortgage is taken in connection with
      such sale, such purchase money mortgage shall name the Seller as mortgagee,
      and
      such purchase money mortgage shall not be held pursuant to this Agreement,
      but
      instead a separate participation agreement among the Seller and Trustee shall
      be
      entered into with respect to such purchase money mortgage. Notwithstanding
      anything herein to the contrary, the Seller shall not be required to provide
      financing for the sale of any REO Property. Notwithstanding any other provisions
      of this Agreement, no REO Property acquired by the Trust Fund shall be rented
      (or allowed to continue to be rented) or otherwise used or held by or on behalf
      of the Trust Fund in such a manner, pursuant to any terms or for a period that
      would: (i) cause such REO Property to fail to qualify as “foreclosure property”
within the meaning of Section 860G(a)(8) of the Code or (ii) result in the
      imposition of any tax upon any REMIC included in the Trust Fund.
    (iii) by
      adding
      the following paragraph to the end of such section:
    Prior
      to
      acceptance by the Seller of an offer to sell any REO Property, the Seller shall
      notify the Master Servicer of such offer in writing which notification shall
      set
      forth all material terms of said offer (each a “Notice of Sale”). The Master
      Servicer shall be deemed to have approved the sale of any REO Property unless
      the Master Servicer notifies the Seller in writing, within five (5) days after
      its receipt of the related Notice of Sale, that it disapproves of the related
      sale, in which case the Seller shall not proceed with such sale.

                follows: | 
On
      each
      Remittance Date the Seller shall remit on an actual/actual basis by wire
      transfer of immediately available funds to the Master Servicer (a) all amounts
      deposited in the Custodial Account as of the close of business on the last
      day
      of the related Due Period (net of charges against or withdrawals from the
      Custodial Account pursuant to Sections 2.04 and 2.05), plus (b) all Monthly
      Advances, if any, which the Seller is obligated to make pursuant to Section
      3.03, and minus (c) any amounts attributable to Principal Prepayments,
      Liquidation Proceeds, Insurance Proceeds, Condemnation Proceeds or REO
      Disposition Proceeds received after the applicable Prepayment Period, which
      amounts shall be remitted on the following Remittance Date, together with any
      additional interest required to be deposited in the Custodial Account in
      connection with such Principal Prepayment in accordance with Section
      2.04(xi).
    With
      respect to any remittance received by the Master Servicer after the Business
      Day
      on which such payment was due, the Seller shall pay to the Master Servicer
      interest on any such late payment at an annual rate equal to the Prime Rate,
      adjusted as of the date of each change, plus two (2) percentage points, but
      in
      no event greater than the maximum amount permitted by applicable law. Such
      interest shall be deposited in the Custodial Account by the Seller on the date
      such late payment is made and shall cover the period commencing with the day
      following such Business Day and ending with the Business Day on which such
      payment is made, both inclusive. Such interest shall be remitted along with
      the
      distribution payable on the next succeeding Remittance Date. The payment by
      the
      Seller of any such interest shall not be deemed an extension of time for payment
      or a waiver of any Event of Default by the Seller.
    All
      remittances required to be made to the Master Servicer shall be made to the
      following wire account or to such other account as may be specified by the
      Master Servicer from time to time:

      parties may sustain in any way related to the failure of the Seller to perform

      may
      be entered against it or any of such parties in respect of such claim. The

      to any of the rights and obligations of the parties pursuant to this Agreement
      and such dispute is adjudicated in a court of law, by an arbitration panel
      or
      any other judicial process, then the losing party shall indemnify and reimburse
      the winning party for all attorney’s fees and other costs and expenses related
      to the adjudication of said dispute.

      that the Seller may assign its rights and obligations hereunder without prior
      written consent of the Trustee and the Master Servicer to any entity that is

                is hereby added to read. | 
It
      is
      understood and agreed that the representations and warranties set forth in
      this
      Article X are hereby restated as of the Closing Date and shall survive the
      engagement of the Seller to perform the servicing responsibilities hereunder
      and
      the delivery of the Servicing Files to the Seller and shall inure to the benefit
      of the Trustee, the Trust Fund and the Master Servicer. Upon discovery by any

      materially and adversely affects the ability of the Seller to perform its duties
      and obligations under this Agreement or otherwise materially and adversely
      affects the value of the Loans, the Mortgaged Property or the priority of the
      security interest on such Mortgaged Property, 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 Master Servicer’s option,
      assign the Seller’s rights and obligations under this Agreement (or respecting
      the affected Mortgage Loans) to a successor servicer selected by the Master
      Servicer with the prior consent and approval of the Trustee. Such assignment
      shall be made in accordance with Article VI.
    In
      addition, the Seller shall indemnify (from its own funds) the Trustee, the

      Fund and Master Servicer and hold each of them harmless against any costs

      discovery of such breach by the Seller or notice thereof by the Trustee or
      Master Servicer to the Seller, (ii) failure by the Seller to cure such breach
      within the applicable cure period, and (iii) demand upon the Seller by the
      Trustee or the Master Servicer for compliance with this Agreement.

(a) Amending
      Subsection 11.01(f) in its entirety to read as follows: “the Seller at any time
      is neither a ▇▇▇▇▇▇ Mae or ▇▇▇▇▇▇▇ Mac approved servicer, and the Master
      Servicer has not terminated the rights and obligations of the Seller under
      this
      Agreement and replaced the Seller with a ▇▇▇▇▇▇ Mae or ▇▇▇▇▇▇▇ Mac approved

    (b) Replacing
      the last paragraph thereof with the following:

      entity designated by the Seller any and all documents and other instruments,
      place in such successor’s possession all Servicing Files, and do or cause to be
      done all other acts or things necessary or appropriate to effect the purposes
      of
      such notice of termination, including but not limited to the transfer and
      endorsement or assignment of the Mortgage Loans and related documents, at the

      and the Master Servicer and such successor in effecting the termination of
      the
      Seller’s responsibilities and rights hereunder, including without limitation,
      the transfer to such successor for administration by it of all cash amounts
      which shall at the time be credited by the Seller to the Custodial Account
      or
      Escrow Account or thereafter received with respect to the Mortgage
      Loans.
    | 32. | The
                parties hereto acknowledge that the word “Purchaser” in Section 11.02
                (Waiver of Defaults) shall refer to the “Master
                Servicer”. | 
| 33. | A
                new Section 11.03 (Termination Without Cause) is hereby added to
                read as
                follows: | 
Section
      11.03 Termination
      Without Cause.
    This
      Agreement shall terminate upon: (i) the later of (a) the distribution of the
      final payment or liquidation proceeds on the last Mortgage Loan to the Trust
      Fund (or advances by the Seller for the same), and (b) the disposition of all
      REO Property acquired upon foreclosure of the last Mortgage Loan and the
      remittance of all funds due hereunder, or (ii) mutual consent of the Seller,
      ▇▇▇▇▇▇ Brothers Bank, FSB and the Master Servicer in writing or (iii) at the
      sole option of the ▇▇▇▇▇▇ Brothers Bank, FSB, without cause, upon 30 days
      written notice. Any such notice of termination shall be in writing and delivered
      to the Seller by registered mail to the address set forth at the beginning
      of
      this Agreement. The Master Servicer, the Trustee and the Seller shall comply
      with the termination procedures set forth in Sections 11.01 and
      11.03.
    A-12
        In
      connection with any such termination referred to in clause (ii) or (iii) above,
      ▇▇▇▇▇▇ Brothers Bank, FSB will be responsible for reimbursing the Seller for
      all
      unreimbursed out-of-pocket Servicing Advances within 15 Business Days following
      the date of termination and other reasonable and necessary out-of-pocket costs
      associated with any transfer of servicing.
    | 34. | A
                new Section 11.04 (Successor to the Seller) is hereby added to read
                as
                follows:  | 
Simultaneously
      with the termination of the Seller’s responsibilities and duties under this
      Agreement pursuant to Sections 8.03, 11.01 or 11.03, the Master Servicer shall,
      in accordance with the provisions of the Trust Agreement (i) succeed to and
      assume all of the Seller’s responsibilities, rights, duties and obligations
      under this Agreement, or (ii) appoint a successor that meets the eligibility
      requirements of this Agreement and that shall succeed to all rights and assume
      all of the responsibilities, duties and liabilities of the Seller under this
      Agreement with the termination of the Seller’s responsibilities, duties and
      liabilities under this Agreement. Any successor to the Seller that is not at
      that time a Seller of other mortgage loans for the Trust Fund shall be subject
      to the approval of the Master Servicer, ▇▇▇▇▇▇ Brothers Bank, FSB, the Trustee
      and each Rating Agency (as such term is defined in the Trust Agreement). Unless
      the successor servicer is at that time a servicer of other mortgage loans for
      the Trust Fund, each Rating Agency must deliver to the Trustee a letter to
      the
      effect that such transfer of servicing will not result in a qualification,
      withdrawal or downgrade of the then-current rating of any of the Certificates.
      In connection with such appointment and assumption, the Master Servicer or
      ▇▇▇▇▇▇ Brothers Bank, as applicable, may make such arrangements for the
      compensation of such successor out of payments on the Mortgage Loans as it
      and
      such successor shall agree; provided, however, that no such compensation shall
      be in excess of that permitted the Seller under this Agreement. In the event
      that the Seller’s duties, responsibilities and liabilities under this Agreement
      should be terminated pursuant to the aforementioned sections, the Seller shall
      discharge such duties and responsibilities during the period from the date
      it
      acquires knowledge of such termination until the effective date thereof with
      the
      same degree of diligence and prudence which it is obligated to exercise under
      this Agreement, and shall take no action whatsoever that might impair or
      prejudice the rights or financial condition of its successor. The resignation
      or
      removal of the Seller pursuant to the aforementioned sections shall not become
      effective until a successor shall be appointed pursuant to this Section 11.04
      and shall in no event relieve the Seller of the representations and warranties
      made pursuant to Article X shall be applicable to the Seller notwithstanding
      any
      such resignation or termination of the Seller, or the termination of this
      Agreement.
    Within
      a
      reasonable period of time, but in no event longer than 30 days of the
      appointment of a successor entity, the Seller shall prepare, execute and deliver
      to the successor entity any and all documents and other instruments, place
      in
      such successor’s possession all Servicing Files, and do or cause to be done all
      other acts or things necessary or appropriate to effect the purposes of such
      notice of termination. The Seller shall cooperate with the Trustee and the
      Master Servicer, as applicable, and such successor in effecting the termination
      of the Seller’s responsibilities and rights hereunder and the transfer of
      servicing responsibilities to the successor Seller, including without
      limitation, the transfer to such successor for administration by it of all
      cash
      amounts which shall at the time be credited by the Seller to the Custodial
      Account or any Escrow Account or thereafter received with respect to the
      Mortgage Loans.
    A-13
        Any
      successor appointed as provided herein shall execute, acknowledge and deliver
      to
      the Trustee, the Seller and the Master Servicer an instrument (i) accepting
      such
      appointment, wherein the successor shall make an assumption of the due and
      punctual performance and observance of each covenant and condition to be
      performed and observed by the Seller under this Agreement, whereupon such
      successor shall become fully vested with all the rights, powers, duties,
      responsibilities, obligations and liabilities of the Seller, with like effect
      as
      if originally named as a party to this Agreement. Any termination or resignation
      of the Seller or termination of this Agreement pursuant to Sections 11.01 or
      11.03 shall not affect any claims that the Master Servicer or the Trustee may
      have against the Seller arising out of the Seller’s actions or failure to act
      prior to any such termination or resignation.
    The
      Seller shall deliver within three (3) Business Days to the successor seller
      the
      funds in the Custodial Account and Escrow Account and all Mortgage Loan
      Documents and related documents and statements held by it hereunder and the
      Seller shall account for all funds and shall execute and deliver such
      instruments and do such other things as may reasonably be required to more
      fully
      and definitively vest in the successor all such rights, powers, duties,
      responsibilities, obligations and liabilities of the Seller.
    Upon
      a
      successor’s acceptance of appointment as such, the Seller shall notify the
      Trustee and Master Servicer of such appointment in accordance with the notice
      procedures set forth herein.
    Except
      as
      otherwise provided in this Agreement, all reasonable costs and expenses incurred
      in connection with any transfer of servicing hereunder (whether as a result
      of
      termination or removal of the Seller or resignation of the Seller or otherwise),
      including, without limitation, the costs and expenses of the Master Servicer
      or
      any other Person in appointing a successor servicer, or of the Master Servicer
      in assuming the responsibilities of the Seller hereunder, or of transferring
      the
      Servicing Files and the other necessary data to the successor servicer shall
      be
      paid by the terminated, removed or resigning Seller from its own funds without
      reimbursement.
    | 35. | The
                second sentence of Section 12.03 (Entire Agreement; Amendment) is
                hereby
                amended and restated in its entirety as
                follows: | 
This
      Agreement may be amended from time to time by written agreement signed by the
      Seller and the Purchaser, with the written consent of the Master Servicer,
      NIMS
      Insurer and the Trustee.
    | 36. | A
                new Section 12.10 (Intended Third Party Beneficiaries) is hereby
                added to
                read as follows:  | 
Notwithstanding
      any provision herein to the contrary, the parties to this Agreement agree that
      it is appropriate, in furtherance of the intent of such parties as set forth
      herein, that the Master Servicer, the Depositor and the Trustee receive the
      benefit of the provisions of this Agreement as intended third party
      beneficiaries of this Agreement to the extent of such provisions. The Seller
      shall have the same obligations to the Master Servicer, the Depositor and the
      Trustee as if they were parties to this Agreement, and the Master Servicer,
      the
      Depositor and the Trustee shall have the same rights and remedies to enforce
      the
      provisions of this Agreement as if they were parties to this Agreement. The
      Seller shall only take direction from the Master Servicer (if direction by
      the
      Master Servicer is required under this Agreement) unless otherwise directed
      by
      this Agreement. Notwithstanding the foregoing, all rights and obligations of
      the
      Master Servicer, the Depositor and the Trustee hereunder (other than the right
      to indemnification) shall terminate upon termination of the Trust Agreement
      and
      of the Trust Fund pursuant to the Trust Agreement.
    | 37. | Exhibit
                8 (Servicing Criteria to be Addressed in Assessment of Compliance)
