                  WHEREAS, the Seller desires that the Servicer continue to
service the Serviced Mortgage Loans, and the Servicer has agreed to do so,
subject to the rights of the Seller and the Master Servicer to terminate the

other conditions set forth herein.
                  WHEREAS, the Seller and the Servicer agree that the provisions
of the SWSA shall apply to the Serviced Mortgage Loans, but only to the extent
provided herein and that this Agreement shall govern the Serviced Mortgage Loans

the Trust Agreement.
                  WHEREAS, the Master Servicer and any successor master servicer
shall be obligated, among other things, to supervise the servicing of the
Serviced Mortgage Loans on behalf of the Trustee, and shall have the right,
under certain circumstances, to terminate the rights and obligations of the
Servicer under this Agreement.
                                        1
                  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.
                  NOW, THEREFORE, in consideration of the mutual agreements
hereinafter set forth 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 SWSA
incorporated by reference herein (regardless of whether such terms are defined
in the SWSA), shall have the meanings ascribed to such terms in the Trust
Agreement.
         2. Custodianship. The parties hereto acknowledge that U.S. Bank
National Association will act as custodian of the Servicing Files for the
Trustee pursuant to a Custodial Agreement, dated August 1, 2005, between U.S.
Bank National Association and the Trustee.
         3. Servicing. The Servicer agrees, with respect to the Serviced
Mortgage Loans, to perform and observe the duties, responsibilities and
obligations that are to be performed and observed under the provisions of the
SWSA, except as otherwise provided herein and on Exhibit A hereto, and the
parties hereto agree that the provisions of the SWSA, as so modified, are and
shall be a part of this Agreement to the same extent as if set forth herein in
full.
         4. Trust Cut-off Date. The parties hereto acknowledge that by operation
of Section 4.05 and Section 5.01 of the SWSA, the remittance on September 18,
2005 to the Trust Fund is to include principal due after August 1, 2005 (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

         5. Master Servicing; Termination of Servicer. The Servicer, including
any successor servicer hereunder, shall be subject to the supervision of the

Servicer services the Serviced Mortgage Loans in accordance with the provisions
of this Agreement. The Master Servicer, acting on behalf of the Trustee and the
▇▇▇▇ ▇▇▇▇-▇▇▇▇ Trust Fund (the "Trust Fund") created pursuant to the Trust
Agreement, shall have the same rights as the Seller under the SWSA to enforce
the obligations of the Servicer under the SWSA and the term "Purchaser" as used
in the SWSA 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 Section 10.01 of the SWSA.
Notwithstanding anything herein to the contrary, in no event shall the Master
Servicer assume any of the obligations of the Seller under the SWSA 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.

with the transactions contemplated by the Trust Agreement and issuance of the

         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 it is appropriate, in furtherance of the intent of
such parties as set forth herein, that the NIMS Insurer receive the benefit of

                  NIM Security shall mean any net interest margin security
issued by an owner trust or special purpose entity that is holding all rights,

                  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-I and Class X-II
Certificates issued by the Trust Fund.
         11. Distressed Mortgage Loans. The NIMS Insurer may, at its option,
purchase a Distressed Mortgage Loan; provided, however, prior to any such
purchase, the Servicer shall be required to continue to make Monthly Advances
with respect to such Distressed Mortgage Loans, to the extent required by the
applicable servicing provisions in the SWSA. 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
SWSA, 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 SWSA. 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.

          commitment providing for such investment the commercial paper or other
          short-term debt obligations of such depository institution or trust
          company (or, in the case of a depository institution or trust company

          providing for such investment, at least equal to one of the two
          highest long-term credit rating categories of each Rating Agency;
          provided, however, that securities issued by any particular
          corporation will not be Eligible Investments to the extent that

               (vii) certificates or receipts representing direct ownership
          interests in future interest or principal payments on obligations of
          the United States of America or its agencies or instrumentalities
          (which obligations are backed by the full faith and credit of the
          United States of America) held by a custodian in safekeeping on behalf
          of the holders of such receipts; and
               (viii) any other demand, money market, common trust fund or time
          deposit or obligation, or interest-bearing or other security or
          investment, (A) rated in the highest rating category by each Rating
          Agency or (B) that would not adversely affect the then current rating
          by each Rating Agency of any of the Certificates. Such investments in
          this subsection (viii) may include money market mutual funds or common
          trust funds, including any fund for which the Trustee, the Master
          Servicer or an affiliate thereof serves as an investment advisor,

          converge at any time; provided, however, that no such instrument shall
          be an Eligible Investment if such instrument evidences either (i) a
          right to receive only interest payments with respect to the
          obligations underlying such instrument, or (ii) both principal and
          interest payments derived from obligations underlying such instrument
          and the principal and interest payments with respect to such
          instrument provide a yield to maturity of greater than 120% of the
          yield to maturity at par of such underlying obligations.

          hereby restated as of the Closing Date and shall survive the
          engagement of the Company to perform the servicing responsibilities
          hereunder and the delivery of the Servicing Files to the Company and
          shall inure to the benefit of the Trustee, the Trust Fund and the
          Master Servicer. Upon discovery by either the Company, the Master
          Servicer or the Trustee of a breach of any of the foregoing
          representations and warranties which materially and adversely affects
          the ability of the Company to perform its duties and obligations under
          this Agreement or otherwise materially and adversely affects the value
          of the Mortgage Loans, the Mortgaged Property or the priority of the
          security interest on such Mortgaged Property or the interest of the
          Trustee or the Trust Fund, the party discovering such breach shall
          give prompt written notice to the other.
               Within 60 days of the earlier of either discovery by or notice to
          the Company of any breach of a representation or warranty set forth in
          Section 3.01 which materially and adversely affects the ability of the

          be cured, the Company shall, at the Master Servicer's option, assign
          the Company'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

          or assertion based on or grounded upon, or resulting from, a breach of
          the Company's representations and warranties contained in this
          Agreement. It is understood and agreed that the remedies set forth in

          the Trust Fund and the Trustee respecting a breach of the foregoing
          representations and warranties.
                                      A-4

          Company or notice thereof by the Trustee or Master Servicer to the
          Company, (ii) failure by the Company to cure such breach within the
          applicable cure period, and (iii) demand upon the Company by the

               (i) by deleting the first sentence of the second paragraph of
          such section and replacing it with the following:
                        Consistent with the terms of this Agreement, the
               Company may waive, modify or vary any term of any Mortgage
               Loan or consent to the postponement of any such term or in any
               manner grant indulgence to any Mortgagor if in the Company's
               reasonable and prudent determination such waiver,
               modification, postponement or indulgence is not materially
               adverse to the Purchaser, provided, however, that unless the
               Mortgagor is in default with respect to the Mortgage Loan or
               such default is, in the judgment of the Company, imminent, the
               Company shall not permit any modification with respect to any
               Mortgage Loan that would change the Mortgage Interest Rate,
               forgive the payment of principal or interest, reduce or
               increase the outstanding principal balance (except for actual
               payments of principal) or change the final maturity date on
               such Mortgage Loan.
               (ii) by adding the following to the end of the second paragraph
          of such section:
               Promptly after the execution of any assumption, modification,
               consolidation or extension of any Mortgage Loan, the Company
               shall forward to the Master Servicer copies of any documents
               evidencing such assumption, modification, consolidation or
               extension. Notwithstanding anything to the contrary contained
               in this Agreement, the Company shall not make or permit any
               modification, waiver or amendment of any term of any Mortgage
               Loan that would cause any REMIC created under the Trust
               Agreement to fail to qualify as a REMIC or result in the
               imposition of any tax under Section 860F(a) or Section 860G(d)
               of the Code.
16.  Section 4.04 (Establishment of and Deposits to Custodial Account) is hereby

               various Mortgagors" in the fourth and fifth lines of the first
               sentence of the first paragraph shall be replaced by the
               following: "in trust for ▇▇▇▇ ▇▇▇▇-▇▇▇▇ Trust Fund and various
               Mortgagors".
17.  Section 4.05 (Permitted Withdrawals From Custodial Account) is hereby
     amended by replacing the words from the word "Purchaser" in the sixth line
     of clause (ii) to the end of such clause (ii) with the following:
                        the Trust Fund; provided however, that in the event
               that the Company determines in good faith that any
               unreimbursed Monthly Advances will not be recoverable from
               amounts representing late recoveries of payments of principal
               or interest respecting the particular Mortgage Loan as to
               which such Monthly Advance was made or from Liquidation
               Proceeds or Insurance Proceeds with respect to such Mortgage
               Loan, the Company may reimburse itself for such amounts from
               the Custodial Account, it being understood, in the case of any
               such reimbursement, that the Company's right thereto shall be
               prior to the rights of the Trust Fund;
                                      A-5
18.  Section 4.06 (Establishment of and Deposits to Escrow Account) shall be
     amended by deleting the words "Purchaser of Conventional Residential
     Mortgage Loans, and various Mortgagors" in the fifth line of the first
     sentence of the first paragraph, and replacing it with the following:
               "in trust for ▇▇▇▇ ▇▇▇▇-▇▇▇▇ Trust Fund and various Mortgagors."
19.  Section 4.15 (Maintenance of LPMI Policy; Claims) is hereby amended by
     adding the following sentence to the end of paragraph (a):
               The Servicer will notify the Master Servicer or ▇▇▇▇▇▇
               Brothers Holdings in the event that the LPMI Policy is
               terminated.
20.  Section 4.16 (Title, Management and Disposition of REO Property) is hereby
     amended by (i) replacing the reference to "one year" in the seventh line of
     the third paragraph thereof with "three years" and (ii) adding two new
     paragraphs after the fourth paragraph thereof to read as follows:
               In the event that the Trust Fund acquires any REO Property in
               connection with a default or imminent default on a Mortgage Loan,
               the Company shall dispose of such REO Property not later than the
               end of the third taxable year after the year of its acquisition
               by the Trust Fund unless the Company has applied for and received
               a grant of extension from the Internal Revenue Service to the
               effect that, under the REMIC Provisions and any relevant proposed
               legislation and under applicable state law, the applicable Trust
               REMIC may hold REO Property for a longer period without adversely
               affecting the REMIC status of such REMIC or causing the
               imposition of a federal or state tax upon such REMIC. If the
               Company has received such an extension, then the Company shall
               continue to attempt to sell the REO Property for its fair market
               value for such period longer than three years as such extension
               permits (the "Extended Period"). If the Company has not received
               such an extension and the Company is unable to sell the REO
               Property within the period ending 3 months before the end of such
               third taxable year after its acquisition by the Trust Fund or if
               the Company has received such an extension, and the Company is
               unable to sell the REO Property within the period ending three
               months before the close of the Extended Period, the Company
               shall, before the end of the three year period or the Extended
               Period, as applicable, (i) purchase such REO Property at a price
               equal to the REO Property's fair market value or (ii) auction the
               REO Property to the highest bidder (which may be the Company) in
               an auction reasonably designed to produce a fair price prior to
               the expiration of the three-year period or the Extended Period,
               as the case may be. The Trustee shall sign any document or take
               any other action reasonably requested by the Company which would
               enable the Company, on behalf of the Trust Fund, to request such
               grant of extension.
               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.
                                      A-6
     (iii) replacing the word "advances" in the sixth line of the fifth
     paragraph thereof with "Monthly Advances", and (iv) by adding the
     following to the end of such Section:
          Prior to acceptance by the Company of an offer to sell any REO
          Property, the Company 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 Company 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 Company shall not proceed with such
          sale.
21.  Section 5.01 (Remittances) is hereby amended by adding the following after
     the second paragraph of such Section:
               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:

22.  Section 5.02 (Statements to Purchaser) is hereby amended in its entirety to
     read as follows:
          Section 5.02 Statements to Master Servicer.
               The Company shall deliver or cause to be delivered to the Master

          agreements pursuant to Sections 4.04 and 4.06 within 30 days of the
          Closing Date.
               Not later than the tenth calendar day of each month, the Company

          level accounting data for the period ending on the last Business Day
          of the preceding month in the format mutually agreed to between the
          Company and the Master Servicer. The information required by Exhibit
          E-1 and Exhibit E-2 is limited to that which is readily available to
          the Company and is mutually agreed to by the Company and Master
          Servicer.
23.  Section 9.01 (Indemnification; Third Party Claims) is hereby amended in its
     entirety to read as follows:
               The Company shall indemnify the Trust Fund, the Trustee and the
          Master Servicer and hold each of them harmless against any and all
          claims, losses, damages, penalties, fines, forfeitures, reasonable and
          necessary legal fees and related costs, judgments and any other costs,
                                      A-7
          fees and expenses that any of such parties may sustain in any way
          related to the failure of the Company to perform its duties and
          service the Mortgage Loans in strict compliance with the terms of this
          Agreement. The Company immediately shall notify the Purchaser, the
          Master Servicer and the Trustee or any other relevant party if a claim
          is made by a third party with respect to this Agreement or the
          Mortgage Loans, assume (with the prior written consent of the
          indemnified party) the defense of any such claim and pay all expenses
          in connection therewith, including counsel fees, and promptly pay,
          discharge and satisfy any judgment or decree which may be entered
          against it or any of such parties in respect of such claim. The
          Company shall follow any written instructions received from the
          Trustee in connection with such claim. The Trustee from the assets of
          the Trust Fund promptly shall reimburse the Company for all amounts
          advanced by it pursuant to the preceding sentence except when the
          claim is in any way related to the Company's indemnification pursuant
          to Section 6.02, or the failure of the Company to service and
          administer the Mortgage Loans in strict compliance with the terms of
          this Agreement.
               The Trust Fund shall indemnify the Company and hold it harmless
          against any and all claims, losses, damages, penalties, fines,
          forfeitures, reasonable and necessary legal fees and related costs,
          judgments and any other costs, fees and expenses that the Company may
          sustain in any way related to the failure of the Trustee or the Master
          Servicer to perform its duties in compliance with the terms of this
          Agreement.
               In the event a dispute arises between an indemnified party and
          the Company with respect 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,

          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 Company or any such person against any liability that
          would otherwise be imposed for its disregard for, or failure to
          perform its obligations and duties under this Agreement, or by reason
          of any breach of the terms and conditions of this Agreement. The
          Company and any director, officer, employee or agent of the Company
          shall be entitled to indemnification by the Trust Fund and will be
          held harmless against any loss, liability or expense incurred in
          connection with any legal action relating to this Agreement, the Trust
          Agreement, or the Certificates other than any loss, liability or
          expense incurred by reason of its disregard for, or failure to perform
          its obligations and duties hereunder. The Company and any director,
          officer, employee or agent of the Company may rely in good faith on
          any document of any kind prima facie properly executed and submitted
          by any Person respecting any matters arising hereunder. The Company
          shall be under no obligation to appear in, prosecute or defend any
          legal action that is not incidental to its duties to service the
          Mortgage Loans in accordance with this Agreement and that in its
          opinion may involve it in any expenses or liability; provided,
          however, that the Company may in its sole discretion undertake any
          such action that it may deem necessary or desirable in respect to this
          Agreement and the rights and duties of the parties hereto and the
          interests of the Certificateholders hereunder. In such event, the
          legal expenses and costs of such action and any liability resulting
          therefrom shall be expenses, costs and liabilities of the Trust Fund
          and the Company shall be entitled to be reimbursed therefor out of the
          Custodial Account it maintains as provided by Section 4.05.

25.  Section 10.01 (Events of Default) is hereby amended by:
          (a)  changing any reference to "Purchaser" to "Master Servicer"; and
          (b)  amending subclause (vii) as follows: "the Company at any time is
               neither a ▇▇▇▇▇▇ ▇▇▇ or ▇▇▇▇▇▇▇ Mac approved servicer, and the
               Master Servicer has not terminated the rights and obligations of
               the Company under this Agreement and replaced the Company with a
               ▇▇▇▇▇▇ Mae or ▇▇▇▇▇▇▇ Mac approved servicer within 30 days of the
               absence of such approval; or".
26.  Section 10.02 (Waiver of Defaults) is hereby amended by changing the
     reference to "Purchaser" to "Master Servicer".
27.  Section 11.01 (Termination) is hereby amended by restating subclause (ii)
     thereof to read as below and adding the following sentence after the first
     sentence of Section 11.01:
          (ii) mutual consent of the Company and the Master Servicer in writing,
               provided such termination is also acceptable to the Trustee and
               the Rating Agencies.
               At the time of any termination of the Company pursuant to this
          Section 11.01, the Company shall be entitled to all accrued and unpaid
          Servicing Fees and unreimbursed Servicing Advances and Monthly
          Advances; provided, however, in the event of a termination for cause
          under Sections 10.01 hereof, such unreimbursed amounts shall not be
          reimbursed to the Company until such amounts are received by the Trust
          Fund from the related Mortgage Loans.
28.  Section 11.02 (Termination Without Cause) is hereby amended by replacing
     all references to "Purchaser" with "▇▇▇▇▇▇ Brothers Holdings."
29.  Section 12.01 (Successor to Company) is hereby amended in its entirety to
     read as follows:
               Simultaneously with the termination of the Company's
          responsibilities and duties under this Agreement pursuant to Sections
          9.04, 10.01, 11.01(ii) or 11.02, the Master Servicer shall, in
          accordance with the provisions of the Trust Agreement (i) succeed to
          and assume all of the Company's responsibilities, rights, duties and
          obligations under this Agreement, or (ii) appoint a successor meeting
          the eligibility requirements of this Agreement, and which shall
          succeed to all rights and assume all of the responsibilities, duties
          and liabilities of the Company under this Agreement with the
          termination of the Company's responsibilities, duties and liabilities
          under this Agreement. Any successor to the Company that is not at that
          time a servicer of other mortgage loans for the Trust Fund shall be
          subject to the approval of the Master Servicer, the Purchaser, the
                                      A-9
          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 the
          Purchaser, 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 Company under
          this Agreement. In the event that the Company's duties,
          responsibilities and liabilities under this Agreement should be
          terminated pursuant to the aforementioned sections, the Company 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 Company pursuant to the aforementioned sections shall not become
          effective until a successor shall be appointed pursuant to this
          Section 12.01 and shall in no event relieve the Company of the
          representations and warranties made pursuant to Sections 3.01 and the
          remedies available to the Trust Fund under Section 3.03 shall be
          applicable to the Company notwithstanding any such resignation or
          termination of the Company, 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 Company 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 Company shall cooperate with the Trustee and the
          Master Servicer, as applicable, and such successor in effecting the
          termination of the Company's responsibilities and rights hereunder and
          the transfer of servicing responsibilities to the successor servicer,
          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 Company to the Account or any Escrow Account or
          thereafter received with respect to the Mortgage Loans.
               Any successor appointed as provided herein shall execute,
          acknowledge and deliver to the Trustee, the Company and the Master
          Servicer an instrument 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 Company under this Agreement, whereupon such successor
          shall become fully vested with all the rights, powers, duties,
          responsibilities, obligations and liabilities of the Company, with
          like effect as if originally named as a party to this Agreement. Any
          termination or resignation of the Company or termination of this
          Agreement pursuant to Sections 9.04, 10.01, 11.01 or 11.02 shall not
          affect any claims that (i) the Master Servicer or the Trustee may have
          against the Company arising out of the Company's actions or failure to
          act, or (ii) the Company may have against the Trust Fund, prior to any
          such termination or resignation.
               The Company shall deliver, within three (3) Business Days of the
          appointment of a successor Servicer, the funds in the Custodial
          Account and Escrow Account and all Collateral Files, Credit Files and
          related documents and statements held by it hereunder to the successor
          Servicer and the Company 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 Company.
                                      A-10
               Upon a successor's acceptance of appointment as such, the Company
          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 (as a result of a termination of the Company for
          cause pursuant to Section 10.01), 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 Company hereunder, or of transferring the
          Servicing Files and the other necessary data to the successor servicer
          shall be paid by the terminated Servicer from its own funds without
          reimbursement. The Trust Fund shall be liable for all costs and
          expenses incurred in connection with any transfer of servicing
          hereunder, other than costs and expenses incurred in connection with a
          transfer of servicing for cause as stated above.
30.  Section 12.02 (Amendment) is hereby amended and restated in its entirety as
     follows:
          Section 12.02 (Amendment)
               This Agreement may be amended from time to time by written
          agreement signed by the Company and the Purchaser, with the written
          consent of the Master Servicer, NIMS Insurer and the Trustee.
31.  Section 12.04 (Duration of Agreement) is hereby amended by deleting the
     last sentence thereof.
32.  Section 12.10 (Assignment by Purchaser) is hereby deleted in its entirety.
33.  A new Section 12.12 (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
          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 Company shall have the same
          obligations to the Master Servicer and the Trustee as if they were
          parties to this Agreement, and the Master Servicer 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 Company
          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 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.
34.  A new Section 12.13 (Officer's Certificate) is hereby added to read as
     follows:
               By March 15th of each year beginning March 15, 2006, or at any
          other time upon thirty (30) days written request, an officer of the
          Servicer shall execute and deliver an Officer's Certificate
          substantially in the form of Exhibit F attached hereto, signed by the
          senior officer in charge of servicing of the Servicer or any officer
          to whom that officer reports, to the Master Servicer for the benefit
          of such Master Servicer and its respective officers, directors and
          affiliates. Notwithstanding the foregoing, in the event that as to any
          year a report on Form 10-K is not required to be filed with the
          Securities and Exchange Commission with respect to the related
          securitization transaction for the prior calendar year, then (i) the
          Depositor shall notify the Servicer of that fact, and (ii) the
          Servicer shall not be required to provide the Officer's Certificate
          described in this Section 12.13.
