         1. Definitions. Capitalized terms used and not defined in this
Agreement, including Exhibit A hereto and any provisions of the Interim

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

Agreement in connection with any rights of the Purchaser shall refer to the
Trust Fund or, as the context requires, the Master Servicer acting in its

1.    The definition of "Eligible Investments" in Article I is hereby amended
      and restated 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 institution or trust company (including U.S. subsidiaries of

         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

         company or deposit institution, as the case may be) have been rated by

         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 be Eligible
         Investments if they are published as being under review with negative

         issuance thereof) rated by each Rating Agency in its highest short-term
         rating category;
                  (vi) a Qualified GIC;
                  (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

         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 underlying obligations.

                           (a) be an obligation of an insurance company or other
                  corporation whose long-term debt is rated by each Rating
                  Agency in one of its two highest rating categories or, if such
                  insurance company has no long-term debt, whose claims paying
                  ability is rated by each Rating Agency in one of its two
                  highest rating categories, and whose short-term debt is rated
                  by each Rating Agency in its highest rating category;
                           (b) provide that the Seller may exercise all of the
                  rights under such contract or surety bond without the
                  necessity of taking any action by any other Person;
                           (c) provide that if at any time the then current
                  credit standing of the obligor under such guaranteed
                  investment contract is such that continued investment pursuant
                  to such contract of funds would result in a downgrading of any
                  rating of the Seller, the Seller shall terminate such contract
                  without penalty and be entitled to the return of all funds
                  previously invested thereunder, together with accrued interest
                  thereon at the interest rate provided under such contract to
                  the date of delivery of such funds to the Trustee;
                                      A-3
                           (d) provide that the Seller's interest therein shall
                  be transferable to any successor servicer or the Master
                  Servicer hereunder; and
                           (e) provide that the funds reinvested thereunder and
                  accrued interest thereon be returnable to the Custodial
                  Account, as the case may be, not later than the Business Day
                  prior to any Determination Date.
7.    A new definition of "Rating Agency" is hereby added to Article I to
      immediately follow the definition of "Qualified Insurer", to read as
      follows:
                  "Rating Agency": ▇▇▇▇▇'▇ Investors Service, Inc., Fitch, Inc.
                  or Standard & Poor's, a division of the ▇▇▇▇▇▇-▇▇▇▇ Companies,
                  Inc., or any successor of the foregoing.
8.    Section 2.01 (Seller to Act as Servicer) is hereby amended as follows:
                  (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 Seller 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 Seller'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 Seller, imminent, the Seller 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 Seller
                  shall forward to the Master Servicer copies of any documents
                  evidencing such assumption, modification, consolidation or
                  extension. Notwithstanding anything to the contrary contained
                  in the Interim Servicing Agreement, the Seller 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.
9.    Section 2.03 (Collection of Mortgage Loan Payments) is hereby amended by
      replacing the words "Continuously from the date hereof until the related
      Transfer Date" in the first and second lines thereof with "Continuously
      from the Closing Date until the date the Mortgage Loan ceases to be
      subject to this Agreement".
                                      A-4
10.   Section 2.04 (Establishment of and Deposits to Custodial Account) is
      hereby amended by:
      (i)   replacing the words "▇▇▇▇▇▇ Brothers Bank, FSB, Residential Fixed
            and Adjustable Rate Mortgage Loans, Group No. 2002-2" with the words
            "the SARM 2004-12 Trust Fund".
11.   Section 2.05 (Permitted Withdrawals From Custodial Account) is hereby
      amended by deleting the word "and" at the end of clause (v), by replacing
      the period at the end of clause (vi) with a semicolon and by adding the
      following new clauses (vii) and (viii):
                           (vii) to invest funds in the Custodial Account in
                  Eligible Investments in accordance with Section 2.10; and
                           (viii) to transfer funds to another Qualified
                  Depository in accordance with Section 2.10 hereof.
12.   Section 2.06 (Establishment of and Deposits to Escrow Account) is hereby
      amended by replacing the words "▇▇▇▇▇▇ Brothers Bank, FSB Residential

      Mortgagors" with "the SARM 2004-12 Trust Fund."
13.   Section 2.17 (Title, Management and Disposition of REO Property) is hereby
      amended by:
                  (i)   adding the following paragraph as the third paragraph of
                        such Section:
                           Notwithstanding anything to the contrary contained in
                  this Section 2.17, in connection with a foreclosure or
                  acceptance of a deed in lieu of foreclosure, in the event the
                  Seller has reasonable cause to believe that a Mortgaged
                  Property is contaminated by hazardous or toxic substances or
                  wastes, or if the Trustee or the Master Servicer otherwise
                  requests, an environmental inspection or review of such
                  Mortgaged Property to be conducted by a qualified inspector
                  shall be arranged by the Seller. Upon completion of the
                  inspection, the Seller shall provide the Trustee and the
                  Master Servicer with a written report of such environmental
                  inspection. In the event that the environmental inspection
                  report indicates that the Mortgaged Property is contaminated
                  by hazardous or toxic substances or wastes, the Seller shall
                  not proceed with foreclosure or acceptance of a deed in lieu
                  of foreclosure. In the event that the environmental inspection
                  report is inconclusive as to the whether or not the Mortgaged
                  Property is contaminated by hazardous or toxic substances or
                  wastes, the Seller shall not, without the prior approval of
                  the Master Servicer, proceed with foreclosure or acceptance of
                  a deed in lieu of foreclosure. In such instance, the Master
                  Servicer shall be deemed to have approved such foreclosure or
                  acceptance of a deed in lieu of foreclosure unless the Master
                  Servicer notifies the Seller in writing, within two (2)
                  Business Days after its receipt of written notice of the
                  proposed foreclosure or deed in lieu of foreclosure from the
                  Seller, that it disapproves of the related foreclosure or
                  acceptance of a deed in lieu of foreclosure. The Seller shall
                  be reimbursed for all Servicing Advances made pursuant to this
                  paragraph with respect to the related Mortgaged Property from
                  the Custodial Account.
                  (ii)  replacing the existing third paragraph of such section
                        (before the amendment made by (i) above) by the
                        following paragraph:
                                      A-5
                           The Seller shall use its Best Efforts to dispose of
                  the REO Property as soon as possible and shall sell such REO
                  Property in any event within three years after title has been
                  taken to such REO Property, unless (a) a REMIC election has
                  not been made with respect to the arrangement under which the
                  Mortgage Loans and the REO Property are held, and (b) the
                  Seller determines, and gives an appropriate notice to the
                  Master Servicer to such effect, that a longer period is
                  necessary for the orderly liquidation of such REO Property. If
                  a period longer than three years is permitted under the
                  foregoing sentence and is necessary to sell any REO Property,
                  (i) the Seller shall report monthly to the Master Servicer as
                  to the progress being made in selling such REO Property and
                  (ii) if, with the written consent of the Trustee, a purchase
                  money mortgage is taken in connection with such sale, such
                  purchase money mortgage shall name the Seller as mortgagee,
                  and such purchase money mortgage shall not be held pursuant to
                  this Agreement, but instead a separate participation agreement
                  among the Seller and Trustee shall be entered into with
                  respect to such purchase money mortgage. Notwithstanding
                  anything herein to the contrary, the Seller shall not be
                  required to provide financing for the sale of any REO
                  Property.
                  (iii) adding the following two (2) paragraphs to the end of
                        such section:
                           Prior to acceptance by the Seller of an offer to sell
                  any REO Property, the Seller shall notify the Master Servicer
                  of such offer in writing which notification shall set forth
                  all material terms of said offer (each a "Notice of Sale").
                  The Master Servicer shall be deemed to have approved the sale
                  of any REO Property unless the Master Servicer notifies the
                  Seller in writing, within five (5) days after its receipt of
                  the related Notice of Sale, that it disapproves of the related
                  sale, in which case the Seller shall not proceed with such
                  sale.
                           Notwithstanding any other provisions of this
                  Agreement, no REO Property acquired by the trust fund provided
                  for in the Trust Agreement shall be rented (or allowed to
                  continue to be rented) or otherwise used, held or disposed of
                  by or on behalf of such 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 Internal Revenue Code of
                  1986, as amended (the "Code"), or (ii) subject any REMIC
                  provided for in the Trust Agreement to the imposition of any
                  federal income taxes on income earned from such REO Property,
                  including any taxes imposed by reason of Sections 860F or 860G
                  of the Code, unless the Seller has agreed to indemnify and
                  hold harmless the trust fund provided for in the Trust
                  Agreement with respect to the imposition of any such taxes.
14.   Section 3.02 (Statements to Purchaser) is hereby amended as follows:
                  (i)   by replacing the last paragraph of such Section 3.02 in
                        its entirety with the following paragraph:
                           Beginning with calendar year 2005, the Seller shall
                  prepare and file any and all tax returns, information
                  statements or other filings for the portion of the tax year
                  2004 and the portion of subsequent tax years for which the
                  Seller has serviced some or all of the Mortgage Loans
                  hereunder as such returns, information statements or other
                  filings are required to be delivered to any governmental
                  taxing authority or to the Master Servicer pursuant to any
                  applicable law with respect to the Mortgage Loans and the
                  transactions contemplated hereby. In addition, the Seller
                  shall provide the Master Servicer with such information
                  concerning the Mortgage Loans as is necessary for the Master
                  Servicer to prepare the Trust Fund's federal income tax return
                  as the Master Servicer may reasonably request from time to
                  time.
                                      A-6
15.   Section 4.04 (Annual Statement as to Compliance) is hereby amended by
      replacing "March 31, 2004" with "March 31, 2005."
16.   Section 4.05 (Annual Independent Public Accountants' Servicing Report) is
      hereby amended by replacing "March 31, 2004" with "March 31, 2005."
17.   A new Section 4.07 (SEC Certificate) is hereby added to this Agreement to
      read as follows:
                           Section 4.07 SEC Certificate. At any time upon thirty
                  (30) days written request, and no later than February 28,
                  2005, an officer of the Seller 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 Seller or any officer to whom that officer

                  of such the Master Servicer and their 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

                  which may be entered against it or any of such parties in
                  respect of such claim. The Seller 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 Seller 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 Seller to service

                  its duties in compliance with the terms of this Agreement.
                           Neither the Seller nor any of the directors,
                  officers, employees or agents of the Seller shall be under any
                  liability to ▇▇▇▇▇▇ Brothers Holdings Inc., the Trust Fund,
                  the Depositor, the Trustee or the Master Servicer for any

                  compliance with any standard of care set forth in this
                  Agreement, or any liability which would otherwise be imposed
                  by reason of any breach of the terms and conditions of this
                  Agreement.
                           In the event a dispute arises between an indemnified
                  party and the Seller 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, then the losing party
                  shall indemnify and reimburse the winning party for all
                  attorney's fees and other costs and expenses related to the
                  adjudication of said dispute.
21.   The first paragraph of Section 8.03 (Limitation on Resignation and
      Assignment by Seller) is hereby amended and restated in its entirety to
      read as follows:
                           The Seller shall neither assign this Agreement or the
                  servicing hereunder or 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 Seller shall be fully
                  liable for such tasks as if the Seller 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; provided, however, that the Seller may assign its
                  rights and obligations hereunder without prior written consent
                  of the Trustee and the Master Servicer to any entity that is
                  directly owned or controlled by the Seller, and the Seller
                  guarantees the performance of such entity hereunder. In the
                  event of such assignment by the Seller, the Seller shall
                  provide the Trustee and the Master Servicer with a written
                  statement guaranteeing the successor entity's performance of
                  the Seller's obligations under the Agreement.
22.   A new Section 12.11 (Intended Third Party Beneficiaries) is hereby added
      to read as follows:
                                      A-8
                           Section 12.11 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 Seller 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
                  Seller shall only take direction from the Master Servicer (if
                  direction by the Master Servicer is required under this
                  Agreement) unless otherwise directed by this Agreement.
                  Notwithstanding the foregoing, all rights and obligations of
                  the Master Servicer 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.
23.   A new Section 12.12 (Acknowledgement) is hereby added to read as follows:
                           Section 12.12 Acknowledgement. The Seller hereby
                  acknowledges that the rights of ▇▇▇▇▇▇ Brothers Bank, FSB
                  under the Servicing Agreement, as amended by this Agreement,
                  will be assigned to SASCO under the Mortgage Loan Sale and
                  Assignment Agreement, and subsequently to the Trust Fund under
                  the Trust Agreement and agrees that the Mortgage Loan Sale and
                  Assignment Agreement and the Trust Agreement will constitute
                  an assignment and assumption of the rights of ▇▇▇▇▇▇ Brothers
                  Bank, FSB under the Servicing Agreement to SASCO and the Trust
