     THIS RECONSTITUTED SERVICING AGREEMENT (this "Agreement"), entered into as
of the 1st day of October, 2002, by and between ▇▇▇▇▇▇ BROTHERS BANK, FSB, a
federal savings bank (the "Seller" or "▇▇▇▇▇▇ Brothers Bank, FSB"), and BANK OF

("Aurora," and, together with any successor Master Servicer appointed pursuant

     WHEREAS, the Serviced Mortgage Loans are currently being serviced by the
Servicer pursuant to the MLSAA.
     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 rights and
obligations of the Servicer hereunder as set forth herein and to the other
conditions set forth herein.
     WHEREAS, the Seller and the Servicer agree that the provisions of the MLSSA
shall apply to the Serviced Mortgage Loans, but only to the extent provided
herein, that this Agreement shall govern the Serviced Mortgage Loans for so long
as such Serviced Mortgage Loans remain subject to the provisions of the Trust
Agreement and that the provisions of the MLSSA shall apply to all Mortgage Loans
other than the Serviced Mortgage Loans without giving effect to the terms of
this 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.
     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:

     2. Custodianship. The parties hereto acknowledge that U.S. Bank, National
Association will act as custodian of the Serviced Mortgage Files for the Trustee

the MLSSA, 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
Subsection 11.05 and Subsection 11.15 of the MLSSA, the remittance on November
18, 2002 to the Trust Fund is to include principal due after October 1, 2002

Servicer assume any of obligations of ▇▇▇▇▇▇ Brothers Bank, FSB under the MLSSA
and in connection with the performance of the Master Servicer's duties

Servicer shall be entitled to all of the rights, protections and limitations of
liability afforded to the Master Servicer under the Trust Agreement.
     6. No Representations. Neither the Servicer nor the Master Servicer shall
be obligated or required to make any representations and warranties regarding
the characteristics of the Serviced Mortgage Loans (other than those
representations and warranties made as of the Closing Date defined in the MLSSA
by the Servicer in Subsection 7.01 of the MLSSA) in connection with the

1.   Unless otherwise specified herein, any provisions of the MLSSA, including
     definitions, relating to (i) representations and warranties relating to the
     Mortgage Loans and not relating to the servicing of the Mortgage Loans,
     (ii) Mortgage Loan repurchase obligations, (iii) Whole-Loan Transfers,

     follows:
          Best Efforts: Efforts determined to be reasonably diligent by the
          Servicer in its reasonable discretion. Such efforts do not require the

          quasi-legal proceeding, nor do they require the Servicer to advance or
          expend fees or sums of money in addition to those specifically set
          forth in this Agreement.
3.   The definition of "Eligible Investments" in Section 1 is hereby amended in
     its entirety to read as follows:

               (ii) federal funds, or demand and time deposits in, certificates
          of deposits of, or bankers' acceptances issued by, any depository

          its respective commercial capacity) incorporated or organized under
          the laws of the United States of America or any state thereof and
          subject to supervision and examination by federal or state banking
          authorities, so long as at the time of investment or the contractual
          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
          which is the principal subsidiary of a holding company, the commercial
          paper or other short-term debt or deposit obligations of such holding
          company or deposit institution, as the case may be) have been rated by

          short-term rating category;
               (iv) securities bearing interest or sold at a discount issued by
          any corporation incorporated under the laws of the United States of

          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
          investment therein will cause the then outstanding principal amount of
          securities issued by such corporation and held as part of the Trust
          Fund to exceed 20% of the sum of the aggregate principal balance of
          the Mortgage Loans; provided, further, that such securities will not

               (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,
          administrator, shareholder servicing agent, and/or custodian or
          subcustodian, notwithstanding that (x) the Trustee, the Master

          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 underlying obligations.

     reference to "Monthly Advance"):
          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 considerations of the Servicer forming the basis of such
          determination, which shall include a copy of any broker's price
          opinion and any other information or reports obtained by the Servicer
          which may support such determinations.

          Loan that was subject to a voluntary (not including discounted
          payoffs) Principal Prepayment in full or in part during any Due
          Period, which Principal Prepayment was applied to such Mortgage Loan
          prior to such Mortgage Loan's Due Date in such Due Period, the amount
          of interest (net of the related Servicing Fee for Principal
          Prepayments in full only) that would have accrued on the amount of
          such Principal Prepayment during the period commencing on the date as
          of which such Principal Prepayment was applied to such Mortgage Loan
          and ending on the day immediately preceding such Due Date, inclusive;
          provided, however, that the Servicer's aggregate obligations to pay
          the Prepayment Interest Shortfall Amount for any month shall be
          limited to the total amount of Servicing Fees actually received with

          security interest on such Mortgaged Property, the Servicer shall use
          its Best Efforts promptly to cure such breach in all material respects

          approval of the Master Servicer. Such assignment shall be made in
          accordance with Subsection 14.03.
               In addition, the Servicer shall indemnify (from its own funds)

          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

          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 Servicer's reasonable and prudent determination
          such waiver, modification, postponement or indulgence is not
          materially adverse to the Master Servicer, the Trustee or the Trust,
          provided, however, that unless the Mortgagor is in default with
          respect to the Mortgage Loan or such default is, in the judgment of
          the Servicer, imminent, the Servicer 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.

               Promptly after the execution of any assumption, modification,

          assumption, modification, consolidation or extension. Notwithstanding
          anything to the contrary contained in this Agreement, the Servicer
          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

                    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

                    the Servicer may reimburse itself for such amounts from the

30.  Subsection 11.13 (Title, Management and Disposition of REO Property) is
     hereby amended (i) by adding two new paragraphs after the second 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
          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
                                      A-8
          the Extended Period, the Servicer 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 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;
          (ii) by replacing the word "advances" in the eighth line of the third
               paragraph thereof with "Monthly Advances"; and,
          (iii) by adding the following to the end of such Subsection:
          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.
31.  Subsection 11.15 (Distributions) is hereby amended by adding the following
     after the second paragraph of such Subsection:
               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:

          fulfillment of all such obligations, specifying each such default
          known to such officer and the nature and status thereof including the
          steps being taken by the Servicer to remedy such default.

               The Servicer shall indemnify ▇▇▇▇▇▇ Brothers Bank, FSB, the Trust
          Fund, the Trustee and the Master Servicer and hold each of them
          harmless against any and all claims, losses, damages, penalties,

          shall notify ▇▇▇▇▇▇ Brothers Bank, FSB, 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, which
          consent shall not be unreasonably withheld or delayed) 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

          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

          relates to the failure of the Servicer to service and administer the

36.  Subsection 12.04 (Seller and Servicer Not to Resign) is hereby amended and
     restated in its entirety to read as follows:
          Subsection 12.04 Limitation on Resignation and Assignment by Servicer
               The Servicer shall neither assign this Agreement or the servicing
          hereunder nor delegate its rights or duties hereunder or any portion
          hereof (to other than a third party in the case of outsourcing routine
          tasks such as taxes, insurance and property inspection, in which case
          the Servicer shall be fully liable for such tasks as if the Servicer
          performed them itself) or sell or otherwise dispose of all or
          substantially all of its property or assets without the prior written
          consent of the Trustee and the Master Servicer, which consent shall be
          granted or withheld in the reasonable discretion of such parties or
          upon the
                                      A-11
          determination that the Servicer's duties hereunder are no longer
          permissible under applicable law and such incapacity cannot be cured
          by the Servicer. Any such determination permitting the unilateral
          resignation of the Servicer shall be evidenced by an Opinion of
          Counsel to such effect delivered to the Purchaser, which Opinion of
          Counsel shall be in form and substance acceptable to the Purchaser. No
          such resignation or assignment shall become effective until a
          successor has assumed the Servicer's responsibilities and obligations
          hereunder in accordance with Subsection 14.03. Notwithstanding the
          foregoing, the Servicer may assign its rights and obligations
          hereunder without prior written consent of the Trustee and the Master
          Servicer to any entity that is directly owned or controlled by the
          Servicer, and the Servicer guarantees the performance of such entity
          hereunder. In the event of such assignment by the Servicer, the
          Servicer shall provide the Trustee and the Master Servicer with a
          written statement guaranteeing the successor entity's performance of
          the Servicer's obligations under the Agreement.
37.  Subsection 13.01 (Events of Default) is hereby amended by:
          (a)  changing any reference to "Purchaser" to "Master Servicer"
          (b)  adding the words "within the applicable cure period" after the
               word "remedied" in the fourth line of subclause (b); and
          (c)  amending subclause (g) as follows: "the Servicer at any time is
               neither a ▇▇▇▇▇▇ ▇▇▇ nor ▇▇▇▇▇▇▇ Mac approved servicer, and the
               Master Servicer has not terminated the rights and obligations of
               the Servicer under this Agreement and replaced the Servicer with
               a ▇▇▇▇▇▇ Mae or ▇▇▇▇▇▇▇ Mac approved servicer within 30 days of
               the absence of such approval;".
38.  Subsection 13.02 (Waiver of Defaults) is hereby amended by changing the
     reference to "Purchaser" in such Subsection to "Master Servicer with the
     prior written consent of the Trustee".
39.  Subsection 14.01 (Termination) is hereby amended by (i) changing the word
     "Purchaser" to "▇▇▇▇▇▇ Brothers Bank, FSB."
40.  Subsection 14.02 (Termination of the Servicer Without Cause) is hereby
     amended by replacing the first reference to "Purchaser" with "▇▇▇▇▇▇
     Brothers Bank, FSB (with the prior consent of the Trustee)" and by
     replacing all other references to "Purchaser" with "▇▇▇▇▇▇ Brothers Bank,
     FSB."
41.  Subsection 14.03 (Successors to the Servicer) is hereby amended in its
     entirety to read as follows:
          Subsection 14.03 Successors to the Servicer.
               Simultaneously with the termination of the Servicer's
          responsibilities and duties under this Agreement pursuant to
          Subsections 12.04, 13.01, 14.01 or 14.02, 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
                                      A-12
          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, ▇▇▇▇▇▇ Brothers Bank, FSB, the Trustee and each
          Rating Agency. 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, FSB, 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
          Subsections, 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 Subsections shall not become effective until a
          successor shall be appointed pursuant to this Subsection 14.03 and
          shall in no event relieve the Servicer of the representations and
          warranties made pursuant to Section 7 and the remedies available to
          the Trust Fund under Subsection 7.03 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.
               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 Subsections 12.04, 13.01, 14.01 or 14.02 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 held by it hereunder to the successor Servicer and the
          Servicer shall account for all funds and shall execute and
                                      A-13
          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 transfer of
          servicing hereunder (whether as a result of termination or removal of
          the Servicer or resignation of the Servicer 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 Servicer 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 Servicer from its own funds without reimbursement.
42.  The parties acknowledge that Section 22 shall be inapplicable to this
     Agreement.
43.  Section 25 (Amendment) is hereby amended by replacing the words "by the
     Purchaser, the Seller and the Servicer by written agreement signed by the
     parties hereto" with the words "by written agreement by the Servicer and
     ▇▇▇▇▇▇ Brothers Bank, FSB, with the written consent of the Master Servicer
     and the Trustee".
44.  Section 29 (Successors and Assigns) is hereby deleted in its entirety.
45.  Section 30 (Non-Solicitation) is hereby amended by replacing the words "the
     Purchaser" with "▇▇▇▇▇▇ Brothers Bank, FSB" in each instance.
46.  A new Section 31 (Intended Third Party Beneficiaries) is hereby added below
     Section 30 to read as follows:
          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.
