                  however, that securities issued by any particular corporation

                  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,
                  administrator, shareholder servicing agent, and/or custodian
                  or subcustodian, notwithstanding that (x) the Trustee, the
                  Master Servicer or an affiliate thereof charges and collects
                  fees and expenses from such funds for services rendered, (y)
                  the Trustee, the Master Servicer or an affiliate thereof
                  charges and collects fees and expenses for services rendered
                  pursuant to this Agreement, and (z) services performed for
                  such funds and pursuant to this Agreement may 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

                  successor thereto.
                                       2
6.       The definition of "Monthly Advance" in Article I is hereby amended in
         its entirety to read as follows:
                  "Monthly Advance": With respect to each Remittance Date and
                  each Mortgage Loan, an amount equal to the Monthly Payment
                  (with the interest portion of such Monthly Payment adjusted to
                  the Mortgage Loan Remittance Rate) that was due on the
                  Mortgage Loan on the Due Date in the related Due Period, and
                  that (i) was delinquent at the close of business on the
                  related Determination Date and (ii) was not the subject of a
                  previous Monthly Advance, but only to the extent that such
                  amount is expected, in the reasonable judgment of the
                  Servicer, to be recoverable from collections or other
                  recoveries in respect of such Mortgage Loan. To the extent
                  that the Servicer determines that any such amount is not
                  recoverable from collections or other recoveries in respect of
                  such Mortgage Loan, such determination shall be evidenced by a
                  certificate of a Servicing Officer delivered to the Master
                  Servicer setting forth such determination and the procedures

                  and warranties set forth in Section 3.01 (a) through (h), (k)
                  and (m) shall survive the engagement of the Servicer to

                  Master Servicer or the Trustee of a breach of any of the

                  adversely affects the ability of the Servicer 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.
                                       5
                           Within 60 days of the earlier of either discovery by
                  or notice to the Servicer of any breach of a representation or
                  warranty set forth in Section 3.01 which materially and
                  adversely affects the ability of the Servicer 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 Servicer shall use its best
                  efforts promptly to cure such breach in all material respects
                  and, if such breach cannot be cured, the Servicer shall, at
                  the Trustee's option, assign the Servicer's rights and
                  obligations under this Agreement (or respecting the affected
                  Loans) to a successor Servicer selected by the Trustee with
                  the prior consent and approval of the Master Servicer. Such
                  assignment shall be made in accordance with Section 12.01.
                           In addition, the Servicer shall indemnify (from its
                  own funds) the Trustee, the Trust Fund and Master Servicer and
                  hold each of them harmless against any costs resulting from
                  any claim, demand, defense or assertion based on or grounded
                  upon, or resulting from, a breach of the Servicer's
                  representations and warranties contained in this Agreement. It
                  is understood and agreed that the remedies set forth in this
                  Section 3.01 constitute the sole remedies of the Master
                  Servicer, the Trust Fund and the Trustee respecting a breach
                  of the foregoing representations and warranties.
                           Any cause of action against the Servicer relating to
                  or arising out of the breach of any representations and
                  warranties made in Section 3.01 shall accrue upon (i)
                  discovery of such breach by the Servicer or notice thereof by
                  the Trustee or Master Servicer to the Servicer, (ii) failure
                  by the Servicer to cure such breach within the applicable cure
                  period, and (iii) demand upon the Servicer by the Trustee or
                  the Master Servicer for compliance with this Agreement.

                  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.

                  Servicer's right thereto shall be prior to the rights of the
                  Trust Fund; provided however, that in the event that the
                  Servicer 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
                  Servicer may reimburse itself for such amounts from the
                  Custodial Account, it being understood, in the case of any
                  such reimbursement, that the Servicer's right thereto shall be
                  prior to the rights of the Trust Fund;

         (ii) adding two new paragraphs after the second paragraph thereof to

                  In the event that the Trust Fund acquires any REO Property in
         connection with a default or imminent default on a Mortgage Loan, the
         Servicer 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 Servicer 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 Servicer has received such an extension, then the
         Servicer 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 Servicer has not
         received such an extension and the Servicer 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 Servicer
         has received such an extension, and the Servicer is unable to sell the
         REO Property within the period ending three months before the close of
         the Extended Period, the Servicer shall, before the end of the three
         year period or the Extended Period, as applicable, (i) purchase such
                                       7
         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 Servicer) 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 Servicer which would
         enable the Servicer, 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 by or on behalf of the Trust
         Fund in such a manner or pursuant to any terms 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) subject any
         Trust REMIC to the imposition of any federal income taxes on the income
         earned from such REO Property, including any taxes imposed by reason of
         Sections 860F or 860G(c) of the Code, unless the Servicer has agreed to
         indemnify and hold harmless the Trust Fund with respect to the
         imposition of any such taxes.
         (iii) deleting the first sentence of the third paragraph thereof, (iv)
         replacing the words "one" and "sentence" with "three" and "paragraph",
         respectively, in the fifth line of the third paragraph thereto, and (v)
         replacing the word "advances" in the sixth line of the fifth paragraph
         thereof with "Monthly Advances";
                  (vi)     by adding the following to the end of such Section:
                  Prior to acceptance by the Servicer of an offer to sell any
                  REO Property, the Servicer 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
                  Servicer 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 Servicer shall not proceed with such
                  sale.
26.      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 year, or, if there has been a default in the fulfillment
                  of all such obligations, specifying each such default known to
                  such officer and the nature and status thereof including the

         deleting Subsection (a) and replacing it with the following:
                  (a) The Servicer shall indemnify the Seller, the Trust Fund,
                  the Trustee and the Master Servicer and hold each of them
                  harmless against any and all claims, losses, damages,

                  and service the Mortgage Loans in strict compliance with the
                  terms of this Agreement. The Servicer immediately shall notify
                  the Seller, the Master Servicer and the Trustee or any other
                  relevant party if a claim is made by a third party with

                  the prior written consent of the indemnified party, which
                  consent shall not be unreasonably withheld or delayed) the

                  The Servicer shall follow any written instructions received
                  from the Trustee in connection with such claim. The Servicer
                  shall provide the Trustee with a written report of all
                  expenses and advances incurred by the Servicer pursuant to
                  this Section 9.01, and the Trustee from the assets of the
                  Trust Fund promptly shall reimburse the Servicer for all
                  amounts advanced by it pursuant to the preceding sentence
                  except when the claim is in any way relates to the failure of
                  the Servicer to service and administer the Mortgage Loans in
                  strict compliance with the terms of this Agreement or the
                  gross negligence, bad faith or willful misconduct of this
                  Servicer.
31.      Section 10.01 (Event of Default) is hereby amended by:
                  (a)      changing any reference to "Purchaser" to "Master
                           Servicer"
                  (b)      changing the reference to "five days" to "two
                           Business Days" in subclause (i);
                  (c)      adding the words "within the applicable cure period"
                           after the word "remedied" in the second line of the
                           second paragraph; and
                  (d)      amending subclause (vii) as follows: "the Company at

                           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".
32.      Section 10.02 (Waiver of Defaults) is hereby amended by changing the
         reference to "Purchaser" to "Master Servicer with the prior written
         consent of the Trustee".

         (ii) thereof to read as below and adding the following sentence after
         the first sentence of Section 11.01:
                  (ii)     mutual consent of the Servicer and the Trustee in
                           writing, provided such termination is also acceptable
                           to the Master Servicer and the Rating Agencies.
                           At the time of any termination of the Servicer
                  pursuant to Section 11.01, the Servicer 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 Servicer until such amounts are received by the Trust Fund
                  from the related Mortgage Loans.
34.      The first paragraph of Section 11.02 (Termination Without Cause) is
         hereby amended by replacing the first reference to "Purchaser" with
         "▇▇▇▇▇▇ Brothers Bank FSB" (with the prior consent of the Trustee)" and

         Bank FSB."
35.      Section 12.01 (Successor to Company) is hereby amended in its entirety
         to read as follows:
                                       10
                           Simultaneously with the termination of the Servicer'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 Servicer'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 Servicer under this Agreement with the
                  termination of the Servicer's responsibilities, duties and
                  liabilities under this Agreement. Any successor to the
                  Servicer 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 Seller, 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 the Seller, 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 Servicer
                  under this Agreement. In the event that the Servicer's duties,
                  responsibilities and liabilities under this Agreement should
                  be terminated pursuant to the aforementioned sections, the
                  Servicer 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 Servicer 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 Servicer of the representations and warranties
                  made pursuant to Sections 3.01 and 3.02 and the remedies
                  available to the Trust Fund under Section 3.03 shall be
                  applicable to the Servicer notwithstanding any such
                  resignation or termination of the Servicer, 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 Servicer 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 Servicer shall cooperate with the Trustee and
                  the Master Servicer, as applicable, and such successor in
                  effecting the termination of the Servicer'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 Servicer to the Account or any Escrow Account or
                  thereafter received with respect to the Mortgage Loans.
                                       11
                           Any successor appointed as provided herein shall
                  execute, acknowledge and deliver to the Trustee, the Servicer
                  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
                  Servicer under this Agreement, whereupon such successor shall
                  become fully vested with all the rights, powers, duties,
                  responsibilities, obligations and liabilities of the Servicer,
                  with like effect as if originally named as a party to this
                  Agreement. Any termination or resignation of the Servicer or
                  termination of this Agreement pursuant to Sections 9.04,
                  10.01, 11.01 or 11.02 shall not affect any claims that the
                  Master Servicer or the Trustee may have against the Servicer
                  arising out of the Servicer's actions or failure to act prior
                  to any such termination or resignation.
                           The Servicer shall deliver within three (3) Business
                  Days of the appointment of a successor Servicer the funds in
                  the 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 Servicer 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 Servicer.
                           Upon a successor's acceptance of appointment as such,
                  the Servicer 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

40.      Intended Third Party Beneficiaries. 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 Servicer 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 Servicer 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.
