          This TRUST AGREEMENT, dated as of June 1, 1998 (the "Agreement"), is
by and among STRUCTURED ASSET SECURITIES CORPORATION,  a Delaware corporation,
as depositor (the "Depositor"),  NORWEST BANK MINNESOTA, NATIONAL ASSOCIATION,
as master servicer (the "Master  Servicer"),  and FIRST UNION NATIONAL BANK, a
national  banking  association  with  its  main  office  in  Charlotte,  North
Carolina, as trustee (the "Trustee").

                             PRELIMINARY STATEMENT

          The Depositor has acquired the Mortgage Loans from Lehman Capital, A
Division of Lehman Brothers  Holdings Inc. (the "Seller"),  and at the Closing
Date is the owner of the Mortgage  Loans and the other property being conveyed
by it to the Trustee for inclusion in the Trust Fund. On the Closing Date, the
Depositor will acquire the Certificates  from the Trust Fund, as consideration
for its  transfer  to the  Trust  Fund of the  Mortgage  Loans  and the  other
property  constituting  the Trust Fund. The Depositor has duly  authorized the
execution and delivery of this  Agreement to provide for the conveyance to the
Trustee of the Mortgage  Loans and the other property  constituting  the Trust
Fund. All covenants and agreements made by the Depositor,  the Master Servicer
and the  Trustee  herein  with  respect  to the  Mortgage  Loans and the other
property  constituting  the Trust Fund are for the benefit of the Holders from
time to time of the  Certificates.  The Depositor and the Master  Servicer are

- ---------------------------
(1)      The Class AX1  Certificates  will have no Certificate  Principal Amount
         and  will  accrue  interest  on a  Notional  Amount  equal,  as to  any
         Distribution Date, to the aggregate  Scheduled Principal Balance of the

         Period.  The Aggregate  Notional Amount for the Class AX1  Certificates
         for the initial Interest Accrual Period is  $142,534,738.10.  The Class
         AX1 Certificates will be interest-only Certificates;  accordingly, they
         will not be entitled  to  distributions  of  principal.  Interest  will
         accrue  on  the  applicable   Notional  Amount  with  respect  to  each
         Distribution Date at a per annum rate equal to the weighted average (by
         Scheduled  Principal Balance of the Mortgage Loans) of the Net Mortgage
         of the  Mortgage  Loans  as of the  first  day  of the  calendar  month
         immediately   preceding  such   Distribution   Date  minus  6.75%.  The
         Certificate  Interest Rate for the Class AX1 Certificates for the first
         Interest Accrual Period is 3.3074%.  The Class AX1 Certificates will be
         issued in book-entry form in minimum Percentage Interests of 10%.

(2)      The Class AX2  Certificates  will have no Certificate  Principal Amount
         and will accrue  interest at the  Certificate  Interest  Rate set forth
         above on a Notional Amount equal, as to any  Distribution  Date, to the
         aggregate  Scheduled Principal Balance off the Mortgage Loans as of the
         first  day  of the  related  Interest  Accrual  Period.  The  Aggregate
         Notional Amount of the Class AX2  Certificates for the initial Interest
         Accrual Period is  $142,534,738.10.  The Class AX2 Certificates will be
         interest-only Certificates;  accordingly,  they will not be entitled to
         distributions of principal.  The Class AX2 Certificates  will be issued
         in  certificated  form in a  denomination  equal  to a 100%  Percentage
         Interest.

          As of  the  Cut-off  Date,  the  Mortgage  Loans  had  an  aggregate
Scheduled Principal Balance of $142,534,738.10.

                           ISSUANCE OF CERTIFICATES

          Section 2.01 Creation and  Declaration of Trust Fund;  Conveyance of
Mortgage  Loans.  (a)  Concurrently  with the  execution  and delivery of this
Agreement, the Depositor does hereby transfer,  assign, set over, deposit with
and  otherwise  convey to the Trustee,  without  recourse,  subject to Section
2.02, 2.04, 2.05 and 2.06, in trust, all the right,  title and interest of the
Depositor in and to the Mortgage  Loans.  Such  conveyance  includes,  without
limitation,  the right to all distributions of principal and interest received
on or with respect to the Mortgage  Loans on and after the Cut-off Date (other
than payments of principal  and interest due on or before such date),  and all
such payments due after such date but received prior to such date and intended
by the related Mortgagors to be applied after such date,  together with all of
the Depositor's right, title and interest in and to the Collection Account and
all amounts from time to time  credited to and the proceeds of the  Collection
Account, the Certificate Account and all amounts from time to time credited to
and the proceeds of the Certificate  Account,  any Escrow Account  established
pursuant to Section 9.06 hereof and all amounts from time to time  credited to
and the proceeds of any such Escrow Account, any REO Property and the proceeds
thereof,  the Depositor's  rights under any Insurance  Policies related to the
Mortgage  Loans,  and the  Depositor's  security  interest  in any  collateral
pledged to secure the Mortgage Loans,  including the Mortgaged  Properties and
any Additional  Collateral  and any proceeds of the foregoing,  to have and to
hold, in trust; and the Trustee declares that,  subject to the review provided
for in  Section  2.02,  it has  received  and shall  hold the Trust  Fund,  as
trustee,  in trust, for the benefit and use of the Holders of the Certificates
and for the purposes and subject to the terms and conditions set forth in this
Agreement,  and,  concurrently  with such receipt,  has caused to be executed,
authenticated and delivered to or upon the order of the Depositor, in exchange
for the Trust Fund,  Certificates in the authorized  denominations  evidencing
the entire ownership of the Trust Fund.

          Concurrently with the execution and delivery of this Agreement,  the
Depositor  does hereby  assign to the  Trustee all of its rights and  interest
under the Mortgage  Loan Sale  Agreement,  including  all rights of the Seller
under  the  Servicing  Agreements  and  the  Special  Servicing   Compensation
Agreement to the extent assigned under the Mortgage Loan Sale  Agreement,  and
delegates  its  obligations  thereunder.   The  Trustee  hereby  accepts  such
assignment and delegation, and shall be entitled to exercise all rights of the
Depositor  under the Mortgage Loan Sale Agreement as if, for such purpose,  it
were the  Depositor.  The  foregoing  sale,  transfer,  assignment,  set over,
deposit and  conveyance  does not and is not intended to result in creation or
assumption by the Trustee of any obligation of the Depositor,  the Seller,  or
any other Person in connection  with the Mortgage Loans or any other agreement
or instrument relating thereto except as specifically set forth herein.

          (b) ______ In  connection  with such  transfer and  assignment,  the
Depositor  does hereby  deliver to, and deposit with, or cause to be delivered
to and  deposited  with,  the  Trustee,  and/or  any  custodian  acting on the
Trustee's behalf, if applicable,  the following  documents or instruments with
respect to each  Mortgage  Loan (each a "Mortgage  File") so  transferred  and
assigned:

                    (i) with  respect  to each  Mortgage  Loan,  the  original
          Mortgage Note endorsed  without recourse in proper form to the order
          of the  Trustee,  or in blank  (in  each  case,  with all  necessary
          intervening endorsements as applicable);

                    (ii) the original of any guarantee  executed in connection
          with the Mortgage Note, assigned to the Trustee;

                    (iii)  with  respect  to any  Mortgage  Loan  other than a
          Cooperative  Loan, the original  recorded  Mortgage with evidence of
          recording  indicated  thereon.  If, in connection  with any Mortgage
          Loan,  the  Depositor  cannot  deliver the Mortgage with evidence of
          recording thereon on or prior to the Closing Date because of a delay
          caused by the public  recording  office where such Mortgage has been
          delivered  for  recordation  or because such Mortgage has been lost,
          the Depositor  shall deliver or cause to be delivered to the Trustee
          (or its custodian),  in the case of a delay due to recording, a true
          copy of such  Mortgage,  pending  delivery of the original  thereof,
          together with an Officer's  Certificate of the Depositor  certifying
          that the copy of such  Mortgage  delivered  to the  Trustee  (or its
          custodian) is a true copy and that the original of such Mortgage has
          been forwarded to the public recording office,  or, in the case of a
          Mortgage  that has been lost, a copy thereof  (certified as provided
          for under the laws of the  appropriate  jurisdiction)  and a written
          Opinion of Counsel  acceptable to the Trustee and the Depositor that
          an  original  recorded  Mortgage  is not  required  to  enforce  the
          Trustee's  interest in the Mortgage Loan;  

                    (iv) The  original  of each  assumption,  modification  or
          substitution  agreement, if any, relating to the Mortgage Loans, or,
          as to any assumption,  modification or substitution  agreement which
          cannot be  delivered  on or prior to the Closing  Date  because of a
          delay caused by the public  recording  office where such assumption,
          modification  or  substitution  agreement  has  been  delivered  for
          recordation,  a  photocopy  of  such  assumption,   modification  or
          substitution  agreement,  pending delivery of the original  thereof,
          together with an Officer's  Certificate of the Depositor  certifying
          that  the  copy of such  assumption,  modification  or  substitution
          agreement delivered to the Trustee (or its custodian) is a true copy
          and that the original of such  agreement  has been  forwarded to the
          public recording office;  

                    (v)  with  respect  to any  Mortgage  Loan,  the  original
          Assignment of Mortgage for each Mortgage Loan;

                    (vi) If applicable,  such original intervening assignments
          of the Mortgage,  notice of transfer or equivalent instrument (each,
          an "Intervening Assignment"), as may be necessary to show a complete
          chain of  assignment  from  the  originator,  or,  in the case of an
          Intervening  Assignment  that has been  lost,  a written  Opinion of
          Counsel  acceptable  to the Trustee that such  original  Intervening
          Assignment is not required to enforce the Trustee's  interest in the
          Mortgage Loans;

                    (vii) the original  Primary  Mortgage  Insurance Policy or
          certificate, if private mortgage guaranty insurance is required;

                    (viii) with  respect to any  Mortgage  Loan,  the original
          mortgagee title insurance policy or attorney's  opinion of title and
          abstract of title; and

                    (ix)  the  original  of any  security  agreement,  chattel
          mortgage or equivalent  executed in connection  with the Mortgage or
          as to any security  agreement,  chattel mortgage or their equivalent
          that cannot be  delivered on or prior to the Closing Date because of
          a delay caused by the public  recording  office where such  document
          has been  delivered for  recordation,  a photocopy of such document,
          pending delivery of the original thereof, together with an Officer's
          Certificate  of the  Depositor  certifying  that  the  copy  of such
          security agreement,  chattel mortgage or their equivalent  delivered
          to the  Trustee  (or its  custodian)  is a true  copy  and  that the
          original of such document has been forwarded to the public recording
          office;

         The parties hereto  acknowledge  and agree that the form of endorsement
attached  hereto as  Exhibit  B-4 is  intended  to effect  the  transfer  to the
Trustee,  for the benefit of the  Certificateholders,  of the Mortgage Notes and
the Mortgages.

          (c)  Assignments of Mortgage shall be recorded;  provided,  however,
that such  Assignments  need not be  recorded  if, in the  Opinion  of Counsel
(which must be Independent  counsel)  acceptable to the Trustee and the Rating
Agency,  recording  in such states is not  required  to protect the  Trustee's
interest in the related Mortgage Loans. Subject to the preceding sentence,  as
soon as practicable after the Closing Date, the Trustee, at the expense of the
Depositor, shall cause to be properly recorded in each public recording office
where the Mortgages are recorded  each  Assignment of Mortgage  referred to in
subsection (b)(v) above.

          (d) In instances  where a Title  Insurance  Policy is required to be
delivered to the Trustee under clause (b)(viii) above and is not so delivered,
the  Depositor  will  provide  a copy of such  Title  Insurance  Policy to the
Trustee as promptly as  practicable  after the execution and delivery  hereof,
but in any case within 180 days of the Closing  Date.  

          (e) For Mortgage Loans (if any) that have been prepaid in full after
the Cut-off  Date and prior to the Closing  Date,  the  Depositor,  in lieu of
delivering the above documents,  herewith delivers to the Trustee an Officer's
Certificate  which shall  include a  statement  to the effect that all amounts
received in connection  with such prepayment that are required to be deposited
in the  applicable  Collection  Account  pursuant to Section 4.01 have been so
deposited.  All original documents that are not delivered to the Trustee shall
be held by the Master  Servicer  or the  applicable  Servicer in trust for the
benefit of the  Trustee and the  Certificateholders.

          Section  2.02  Acceptance  of  Trust  Fund  by  Trustee:  Review  of
Documentation  for Trust Fund.  (a) The  Trustee,  by  execution  and delivery
hereof,  acknowledges receipt of the Mortgage Files pertaining to the Mortgage
Loans listed on the Mortgage Loan  Schedule,  subject to review thereof by the
Trustee, or by the applicable  Custodian on behalf of the Trustee,  under this
Section  2.02.  The  Trustee,  or the  applicable  Custodian  on behalf of the
Trustee,  will execute and deliver to the Depositor and the Master Servicer on
the  Closing  Date an  Initial  Certification  in the form  annexed  hereto as
Exhibit B-1.

          (b) Within 45 days after the Closing Date, the applicable  Custodian
will,  on  behalf  of the  Trustee  and  for the  benefit  of  Holders  of the
Certificates,  review  each  Mortgage  File to  ascertain  that  all  required
documents  set forth in Section  2.01 have been  received  and appear on their
face to contain the  requisite  signatures  by or on behalf of the  respective
parties thereto,  and shall deliver to the Depositor,  the Master Servicer and
the Special  Servicer an Interim  Certification  in the form annexed hereto as
Exhibit  B-2 to the  effect  that,  as to each  Mortgage  Loan  listed  in the
Mortgage  Loan  Schedule  (other than any Mortgage Loan prepaid in full or any
Mortgage Loan specifically  identified in such certification as not covered by
such certification),  (i) all of the applicable documents specified in Section
2.01(b) are in its possession and (ii) such documents have been reviewed by it
and appear to relate to such Mortgage  Loan.  The Trustee,  or the  applicable
Custodian on behalf of the  Trustee,  shall make sure that the  documents  are
executed and  endorsed,  but shall be under no duty or  obligation to inspect,
review or  examine  any such  documents,  instruments,  certificates  or other
papers to  determine  that the same are  valid,  binding,  legally  effective,
properly  endorsed,  genuine,  enforceable or appropriate  for the represented
purpose or that they have actually been recorded or are in recordable  form or
that they are other than what they  purport to be on their  face.  Neither the
Trustee nor any  Custodian  shall have any  responsibility  for  verifying the
genuineness or the legal  effectiveness  of or authority for any signatures of
or on behalf of any party or endorser.

          (c) If in the course of the review  described in paragraph (b) above
the Trustee or the  applicable  Custodian  discovers any document or documents
constituting  a part of a  Mortgage  File  that is  missing,  does not  appear
regular on its face (i.e., is mutilated,  damaged,  defaced, torn or otherwise
physically  altered)  or  appears  to  be  unrelated  to  the  Mortgage  Loans
identified in the Mortgage  Loan Schedule  (each,  a "Material  Defect"),  the
Trustee, or the applicable Custodian on behalf of the Trustee,  shall promptly
identify  the  Mortgage  Loan to which  such  Material  Defect  relates in the
Interim Certificate  delivered to the Depositor or the Master Servicer (and to
the  Trustee).  Within 90 days of its receipt of such  notice,  the  Depositor
shall be required  to cure such  Material  Defect  (and,  in such  event,  the
Depositor shall provide the Trustee with an Officer's  Certificate  confirming
that  such cure has been  effected).  If the  Depositor  does not so cure such
Material  Defect,  it shall,  if a loss has been incurred with respect to such
Mortgage Loan that would,  if such  Mortgage Loan were not purchased  from the
Trust Fund,  constitute a Realized Loss, and such loss is  attributable to the
failure of the Depositor to cure such Material Defect,  repurchase the related
Mortgage  Loan from the Trust  Fund at the  Purchase  Price.  A loss  shall be
deemed to be  attributable  to the failure of the Depositor to cure a Material
Defect if, as determined by the  Depositor,  upon mutual  agreement  acting in
good  faith,  absent  such  Material  Defect,  such  loss  would not have been
incurred. Within the two year period following the Closing Date, the Depositor
may, in lieu of  repurchasing  a Mortgage  Loan pursuant to this Section 2.02,
substitute  for such  Mortgage  Loan a  Qualifying  Substitute  Mortgage  Loan
subject to the  provisions of Section 2.05.  The failure of the Trustee or the
applicable  Custodian to give the notice  contemplated  herein  within 45 days
after the  Closing  Date  shall not  affect or relieve  the  Depositor  of its
obligation  to  repurchase  any Mortgage Loan pursuant to this Section 2.02 or
any other Section of this Agreement requiring the repurchase of Mortgage Loans
from the Trust  Fund.  

          (d) Within 180 days following the Closing Date, the Trustee,  or the
applicable Custodian,  shall deliver to the Depositor, the Master Servicer and
the Special Servicer a Final  Certification  substantially in the form annexed
hereto as Exhibit B-3 evidencing the completeness of the Mortgage Files in its
possession  or control.  

          (e) Nothing in this  Agreement  shall be construed to  constitute an
assumption  by the Trust Fund,  the Trustee or the  Certificateholders  of any
unsatisfied  duty,  claim or other  liability on any  Mortgage  Loan or to any
Mortgagor.  

          Section 2.03.  Representations and Warranties of the Depositor.  The
Depositor  hereby  represents and warrants to the Trustee,  for the benefit of
Certificateholders,  and the Master  Servicer,  as of the Closing Date or such
other date as is specified, that:

          (a) the Depositor is a corporation duly organized,  validly existing
and in good standing  under the laws  governing its creation and existence and
has full  corporate  power and authority to own its property,  to carry on its
business as  presently  conducted,  to enter into and perform its  obligations
under this Agreement, and to create the trust pursuant hereto;

          (b) the execution  and delivery by the  Depositor of this  Agreement
have been duly authorized by all necessary corporate action on the part of the
Depositor;  neither the  execution  and  delivery of this  Agreement,  nor the
consummation of the transactions herein contemplated,  nor compliance with the
provisions hereof,  will conflict with or result in a breach of, or constitute
a  default  under,  any  of the  provisions  of any  law,  governmental  rule,
regulation,  judgment,  decree  or  order  binding  on  the  Depositor  or its
properties or the certificate of incorporation or bylaws of the Depositor; 

          (c) the execution, delivery and performance by the Depositor of this
Agreement and the consummation of the transactions  contemplated hereby do not
require the consent or approval of, the giving of notice to, the  registration
with,  or the taking of any other action in respect of, any state,  federal or
other  governmental  authority  or agency,  except such as has been  obtained,
given, effected or taken prior to the date hereof; 

          (d) this  Agreement  has been duly  executed  and  delivered  by the
Depositor  and,  assuming  due  authorization,  execution  and delivery by the
Trustee and the Master Servicer, constitutes a valid and binding obligation of
the Depositor  enforceable  against it in accordance  with its terms except as
such enforceability may be subject to (A) applicable bankruptcy and insolvency
laws and  other  similar  laws  affecting  the  enforcement  of the  rights of
creditors generally and (B) general principles of equity regardless of whether
such  enforcement is considered in a proceeding in equity or at law; 

          (e) there are no actions,  suits or  proceedings  pending or, to the
knowledge of the  Depositor,  threatened  or likely to be asserted  against or
affecting  the  Depositor,  before  or by any  court,  administrative  agency,
arbitrator or  governmental  body (A) with respect to any of the  transactions
contemplated  by this  Agreement or (B) with respect to any other matter which
in the judgment of the Depositor will be determined adversely to the Depositor
and will if  determined  adversely to the Depositor  materially  and adversely
affect it or its  business,  assets,  operations  or  condition,  financial or
otherwise,  or adversely  affect its ability to perform its obligations  under
this Agreement;  

          (f) immediately prior to the transfer and assignment of the Mortgage
Loans to the Trustee, the Depositor was the sole owner of record and holder of
each Mortgage Loan,  and the Depositor had good and marketable  title thereto,
and had full right to transfer and sell each Mortgage Loan to the Trustee free
and  clear,  subject  only to (1) liens of  current  real  property  taxes and
assessments not yet due and payable and, if the related Mortgaged  Property is
a condominium  unit,  any lien for common  charges  permitted by statute,  (2)
covenants,  conditions and  restrictions,  rights of way,  easements and other
matters  of  public  record  as of the  date of  recording  of  such  Mortgage
acceptable to mortgage  lending  institutions in the area in which the related
Mortgaged  Property is located and  specifically  referred to in the  lender's
Title  Insurance  Policy or attorney's  opinion of title and abstract of title
delivered to the  originator of such Mortgage Loan, and (3) such other matters
to which like properties are commonly subject which do not, individually or in
the aggregate, materially interfere with the benefits of the security intended
to be provided by the  Mortgage,  of any  encumbrance,  equity,  participation
interest, lien, pledge, charge, claim or security interest, and had full right
and authority,  subject to no interest or participation of, or agreement with,
any other  party,  to sell and assign  each  Mortgage  Loan  pursuant  to this
Agreement.  

          Section 2.04.  Discovery of Breach. It is understood and agreed that
the  representations  and  warranties  set  forth  in  Section  2.03  and  the
representations  and  warranties  of the Seller set forth in the Mortgage Loan
Sale Agreement and assigned to the Trustee by the Depositor  hereunder survive
delivery of the Mortgage Files and the Assignment of Mortgage of each Mortgage
Loan to the Trustee and shall continue  throughout the term of this Agreement.
Upon discovery by either the Depositor,  the Master Servicer or the Trustee of
a breach of any of such  representations  and  warranties  that  adversely and
materially  affects  the  value  of  the  related  Mortgage  Loan,  the  party
discovering such breach shall give prompt written notice to the other parties.
Within  90  days  of  the  discovery  of  such  breach  with  respect  to  the
representations  and warranties,  the Depositor or the Seller,  as applicable,
shall either (a) cure such breach in all  material  respects,  (b)  repurchase
such  Mortgage  Loan or any  property  acquired  in respect  thereof  from the
Trustee at the Purchase Price or (c) within the two year period  following the
Closing  Date,  substitute  a  Qualifying  Substitute  Mortgage  Loan  for the
affected Mortgage Loan.

          Section  2.05.  Repurchase,  Purchase  or  Substitution  of Mortgage
Loans.  (a) With respect to any Mortgage  Loan  repurchased  by the  Depositor
pursuant to this  Article II or by the Seller  pursuant to the  Mortgage  Loan
Sale Agreement,  the principal portion of the funds received by the Trustee in
respect of such  repurchase  of a Mortgage Loan will be considered a Principal
Prepayment and shall be deposited in the Collection Account. The Trustee, upon
receipt of the full amount of the Purchase Price for a Deleted  Mortgage Loan,
or upon receipt of the Mortgage File for a Qualifying Substitute Mortgage Loan
substituted for a Deleted Mortgage Loan, shall release or cause to be released
and  reassign to the  Depositor  or the  Seller,  as  applicable,  the related
Mortgage File for the Deleted Mortgage Loan and shall execute and deliver such
instruments  of  transfer  or  assignment,  in  each  case  without  recourse,
representation or warranty,  as shall be necessary to vest in the Depositor or
its designee or assignee title to any Deleted Mortgage Loan released  pursuant
hereto, free and clear of all security interests, liens and other encumbrances
created by this Agreement,  which instruments shall be prepared by the Trustee
(or its custodian),  and the Trustee shall have no further responsibility with
respect to the Mortgage File relating to such Deleted  Mortgage Loan. 

          (b) With respect to each Qualifying  Substitute  Mortgage Loan to be
delivered  to the  Trustee  (or its  custodian)  pursuant to the terms of this
Article II in exchange for a Deleted  Mortgage  Loan:  (i) the Depositor  must
deliver to the Trustee (or its custodian) the Mortgage File for the Qualifying
Substitute Mortgage Loan containing the documents set forth in Section 2.01(b)
along  with a written  certification  certifying  as to the  delivery  of such
Mortgage  File and  containing  the  granting  language  set forth in  Section
2.01(a);   and  (ii)  the   Depositor   will  be   deemed  to  have  made  the
representations  and  warranties  set  forth in  Section  2.03(f).  As soon as
practicable  after the delivery of any  Qualifying  Substitute  Mortgage  Loan
hereunder,  the Trustee shall cause the Assignment of Mortgage with respect to
such Qualifying  Substitute  Mortgage Loan to be recorded if required pursuant
to the first sentence of Section 2.01(c).

          (c) Notwithstanding any other provision of this Agreement, the right
to substitute  Mortgage  Loans pursuant to this Article II shall be subject to
the additional  limitations  that no substitution  of a Qualifying  Substitute
Mortgage Loan for a Deleted Mortgage Loan shall be made unless the Trustee has
received an Opinion of Counsel  (at the  expense of the party  seeking to make
the  substitution)  that,  under current law, such  substitution  will not (A)
affect adversely the status of any REMIC established  hereunder as a REMIC, or
of the related "regular  interests" as "regular  interests" in any such REMIC,
or (B)  cause  any such  REMIC to  engage  in a  "prohibited  transaction"  or
prohibited  contribution  pursuant  to the REMIC  Provisions.  

          Section 2.06.  Grant Clause.  It is intended that the  conveyance of
the Depositor's right, title and interest in and to property  constituting the
Trust Fund pursuant to this Agreement shall constitute, and shall be construed
as, a sale of such property and not a grant of a security interest to secure a
loan.  However, if such conveyance is deemed to be in respect of a loan, it is
intended  that:  (1) the  rights  and  obligations  of the  parties  shall  be
established pursuant to the terms of this Agreement;  (2) the Depositor hereby
grants to the Trustee for the  benefit of the  Holders of the  Certificates  a
first priority  security interest in all of the Depositor's  right,  title and
interest in, to and under, whether now owned or hereafter acquired,  the Trust
Fund and all proceeds of any and all property  constituting  the Trust Fund to
secure payment of the Certificates;  and (3) this Agreement shall constitute a
security agreement under applicable law. If such conveyance is deemed to be in
respect of a loan and the Trust created by this Agreement  terminates prior to
the  satisfaction  of the claims of any Person  holding any  Certificate,  the
security  interest  created hereby shall continue in full force and effect and
the Trustee shall be deemed to be the collateral agent for the benefit of such
Person, and all proceeds shall be distributed as herein provided.

          Section  2.07.   Purchase  of  Defaulted  Mortgage  Loans.  (a)  The
Directing  Holder shall have the right to purchase  defaulted  Mortgage  Loans
from the Trust Fund as and to the extent  provided  in the  Special  Servicing
Agreement.  Such right shall be  transferable to and exercisable by subsequent
Holders of the Class of Subordinate Certificates then possessing the rights of
the Directing Holder only upon satisfaction of the conditions set forth in the
Special Servicing Agreement.

          (b) In addition to the purchase option provided under subsection (a)
above,  the Special  Servicer and the Directing Holder shall have the right to
purchase  Severely  Delinquent  Loans (as  defined  in the  Special  Servicing
Agreement)  from the Trust Fund as and to the extent  provided  in the Special
Servicing Agreement. Such right of such Directing Holder shall be transferable
to  and  exercisable  by  subsequent  Holders  of  the  Class  of  Subordinate
Certificates  then  possessing  the rights of the  Directing  Holder only upon
satisfaction of the conditions set forth in the Special Servicing Agreement.

                                 ARTICLE III

                               THE CERTIFICATES

          Section  3.01.  The  Certificates.  (a) The  Certificates  shall  be
issuable in registered form only and shall be securities governed by Article 8
of the New York Uniform  Commercial Code. The Book-Entry  Certificates will be
evidenced by one or more certificates,  beneficial  ownership of which will be
held in the dollar  denominations in Certificate  Principal Amount or Notional
Principal Amount,  as applicable,  or in the Percentage  Interests,  specified
herein.  Each  Class of  Book-Entry  Certificates  other  than the  Class  AX1
Certificates  will be  issued  in the  minimum  denominations  in  Certificate
Principal Amount specified in the Preliminary Statement hereto and in integral
multiples of $1 in excess thereof.  The Class AX1 Certificates  will be issued
in minimum  Percentage  Interests of 10%. Each Class AX2  Certificate and each
Residual  Certificate will be issued as a single Certificate and maintained in
definitive,  fully registered form in a minimum  denomination equal to 100% of
the Percentage  Interest of such Class.  The Certificates may be issued in the
form  of  typewritten   certificates.   One   Certificate  of  each  Class  of
Certificates   other  than  the  Class  AX2   Certificates  and  the  Residual
Certificates  may be issued  in any  denomination  in  excess  of the  minimum
denomination.

          (b) The  Certificates  shall be  executed  by  manual  or  facsimile
signature on behalf of the Trustee by an authorized officer.  Each Certificate
shall, on original issue,  be  authenticated  by the Trustee upon the order of
the Depositor upon receipt by the Trustee of the Mortgage  Files  described in
Section  2.01.  No  Certificate  shall be entitled  to any benefit  under this
Agreement,  or be  valid  for  any  purpose,  unless  there  appears  on  such
Certificate a certificate of authentication substantially in the form provided
for  herein,  executed  by  an  authorized  officer  of  the  Trustee  or  the
Authenticating Agent, if any, by manual signature, and such certification upon
any Certificate shall be conclusive evidence, and the only evidence, that such
Certificate  has  been  duly  authenticated  and  delivered   hereunder.   All
Certificates shall be dated the date of their authentication.  At any time and
from time to time after the  execution  and  delivery of this  Agreement,  the
Depositor may deliver Certificates executed by the Depositor to the Trustee or
the   Authenticating   Agent  for   authentication  and  the  Trustee  or  the
Authenticating  Agent shall  authenticate and deliver such  Certificates as in
this Agreement provided and not otherwise.

          Section  3.02  Registration.  The Trustee is hereby  appointed,  and
hereby accepts its  appointment  as,  Certificate  Registrar in respect of the
Certificates  and  shall  maintain  books  for  the  registration  and for the
transfer of Certificates (the "Certificate Register"). The Trustee may appoint
a bank or trust company to act as Certificate  Registrar.  A registration book
shall  be  maintained  for  the  Certificates  collectively.  The  Certificate
Registrar  may resign or be  discharged  or removed and a new successor may be
appointed in accordance  with the  procedures  and  requirements  set forth in
Sections  6.06 and 6.07 hereof with respect to the  resignation,  discharge or
removal  of the  Trustee  and the  appointment  of a  successor  Trustee.  The
Certificate  Registrar may appoint,  by a written instrument  delivered to the
Holders  and  the  Master  Servicer,  any  bank  or  trust  company  to act as
co-registrar under such conditions as the Certificate Registrar may prescribe;
provided, however, that the Certificate Registrar shall not be relieved of any
of its duties or responsibilities hereunder by reason of such appointment.

          Section  3.03.   Transfer  and  Exchange  of  Certificates.   (a)  A
Certificate  (other  than  Book-Entry  Certificates  which shall be subject to
Section  3.09  hereof)  may be  transferred  by the Holder  thereof  only upon
presentation   and  surrender  of  such  Certificate  at  the  office  of  the
Certificate  Registrar  duly endorsed or  accompanied  by an  assignment  duly
executed by such Holder or his duly authorized  attorney in such form as shall
be  satisfactory  to the  Certificate  Registrar.  Upon  the  transfer  of any
Certificate  in  accordance  with the  preceding  sentence,  the Trustee shall
execute,  and the Trustee or any  Authenticating  Agent shall authenticate and
deliver to the transferee,  one or more new Certificates of the same Class and
evidencing,  in the aggregate, the same aggregate Certificate Principal Amount
as the  Certificate  being  transferred.  No service charge shall be made to a
Certificateholder  for any registration of transfer of  Certificates,  but the
Certificate Registrar may require payment of a sum sufficient to cover any tax
or governmental charge that may be imposed in connection with any registration
of transfer of Certificates.  

          (b) A  Certificate  may be exchanged  by the Holder  thereof for any
number of new  Certificates  of the same Class,  in authorized  denominations,
representing  in the aggregate the same  Certificate  Principal  Amount as the
Certificate surrendered,  upon surrender of the Certificate to be exchanged at
the office of the  Certificate  Registrar  duly endorsed or  accompanied  by a
written  instrument  of  transfer  duly  executed  by such  Holder or his duly
authorized  attorney  in  such  form  as is  satisfactory  to the  Certificate
Registrar.  Certificates  delivered  upon any such  exchange will evidence the
same obligations,  and will be entitled to the same rights and privileges,  as
the  Certificates   surrendered.   No  service  charge  shall  be  made  to  a
Certificateholder  for any  exchange  of  Certificates,  but  the  Certificate
Registrar  may  require  payment  of a sum  sufficient  to  cover  any  tax or
governmental  charge that may be imposed in  connection  with any  exchange of
Certificates.  Whenever any Certificates are so surrendered for exchange,  the
Trustee  shall  execute,  and the  Trustee or the  Authenticating  Agent shall
authenticate,  date and deliver the Certificates  which the  Certificateholder
making the exchange is entitled to receive.

          (c) By acceptance of a Restricted Certificate, whether upon original
issuance  or   subsequent   transfer,   each  Holder  of  such  a  Certificate
acknowledges  the  restrictions on the transfer of such  Certificate set forth
thereon and agrees that it will transfer  such a Certificate  only as provided
herein.

          The following  restrictions shall apply with respect to the transfer
and registration of transfer of a Restricted  Certificate to a transferee that
takes delivery in the form of a Definitive Certificate:

                    (i) The Certificate  Registrar shall register the transfer
          of a Restricted  Certificate if the requested transfer is (x) to the
          Depositor or the Placement  Agent,  an affiliate (as defined in Rule
          144(a)(1)  under the 1933  Act) of the  Depositor  or the  Placement
          Agent or (y)  being  made to a  "qualified  institutional  buyer" as
          defined in Rule 144A under the  Securities  Act of 1933,  as amended
          (the "Act") by a  transferor  who has  provided  the Trustee  with a
          certificate in the form of Exhibit F hereto; and

                    (ii) The Certificate Registrar shall register the transfer
          of a Restricted  Certificate if the requested transfer is being made
          to an "accredited  investor" under Rule  501(a)(1),  (2), (3) or (7)
          under the Act by a transferor  who furnishes to the Trustee a letter
          of the transferee substantially in the form of Exhibit G hereto. 

          (d) (i) No transfer of an  ERISA-Restricted  Certificate in the form
of a Definitive Certificate shall be made to any Person unless the Trustee has
received (A) a certificate  substantially in the form of Exhibit H hereto from
such  transferee or (B) an Opinion of Counsel  satisfactory to the Trustee and
the  Depositor  to  the  effect  that  the  purchase  and  holding  of  such a
Certificate  will not  constitute  or result in the  assets of the Trust  Fund
being  deemed  to be "plan  assets"  subject  to the  prohibited  transactions
provisions  of ERISA or  Section  4975 of the  Code and will not  subject  the
Trustee or the Depositor to any obligation in addition to those  undertaken in
the  Agreement;  provided,  however,  that the Trustee  will not require  such
certificate  or opinion in the event  that,  as a result of a change of law or
otherwise,  counsel satisfactory to the Trustee has rendered an opinion to the
effect that the purchase and holding of an  ERISA-Restricted  Certificate by a
Plan or a Person that is  purchasing  or holding such a  Certificate  with the
assets of a Plan will not  constitute  or result in a  prohibited  transaction
under ERISA or Section 4975 of the Code. The  preparation  and delivery of the
certificate  and  opinions  referred  to above  shall not be an expense of the
Trust Fund, the Trustee or the Depositor.  Notwithstanding  the foregoing,  no
opinion or  certificate  shall be  required  for the  initial  issuance of the
ERISA-Restricted Certificates.

          (e) As a condition  of the  registration  of transfer or exchange of
any Certificate,  the Certificate Registrar may require the certified taxpayer
identification number of the owner of the Certificate and the payment of a sum
sufficient to cover any tax or other governmental charge imposed in connection
therewith;  provided,  however,  that the Certificate  Registrar shall have no
obligation to require such payment or to determine whether or not any such tax
or  charge  may  be  applicable.  No  service  charge  shall  be  made  to the
Certificateholder  for any registration,  transfer or exchange of Certificate.

          (f)  Notwithstanding  anything to the contrary  contained herein, no
Residual  Certificate  may be  owned,  pledged  or  transferred,  directly  or
indirectly, by or to a Disqualified Organization.

          Prior to and as a condition  of the  registration  of any  transfer,
sale or other disposition of a Residual  Certificate,  the proposed transferee
shall deliver to the Trustee an affidavit in  substantially  the form attached
hereto as Exhibit D-1  representing and warranting,  among other things,  that
such transferee is neither a Disqualified Organization nor an agent or nominee
acting on behalf  of a  Disqualified  Organization  (any  such  transferee,  a
"Permitted  Transferee"),  and the proposed  transferor  shall  deliver to the
Trustee an affidavit in substantially the form attached hereto as Exhibit D-2.
In addition,  the Trustee may (but shall have no obligation to) require, prior
to and as a condition  of any such  transfer,  the  delivery  by the  proposed
transferee  of an Opinion  of  Counsel,  addressed  to the  Depositor  and the
Trustee  satisfactory  in form  and  substance  to the  Depositor,  that  such
proposed transferee or, if the proposed transferee is an agent or nominee, the
proposed beneficial owner, is not a Disqualified Organization. Notwithstanding
the registration in the Certificate  Register of any transfer,  sale, or other
disposition of a Residual  Certificate to a  Disqualified  Organization  or an
agent or  nominee  acting  on  behalf  of a  Disqualified  Organization,  such
registration  shall be deemed to be of no legal force or effect whatsoever and
such Disqualified  Organization (or such agent or nominee) shall not be deemed
to be a  Certificateholder  for  any  purpose  hereunder,  including,  but not
limited to, the receipt of  distributions  on such Residual  Certificate.  The
Trustee shall not be under any liability to any person for any registration or
transfer of a Residual  Certificate to a Disqualified  Organization or for the
maturity  of any  payments  due on such  Residual  Certificate  to the  Holder
thereof or for taking any other  action with  respect to such Holder under the
provisions  of  the  Agreement,  so  long  as the  transfer  was  effected  in
accordance  with this Section  3.03(f),  unless the Trustee  shall have actual
knowledge  at the time of such  transfer or the time of such  payment or other
action that the  transferee  is a  Disqualified  Organization  (or an agent or
nominee thereof).  The Trustee shall be entitled to recover from any Holder of
a Residual  Certificate  that was a Disqualified  Organization (or an agent or
nominee  thereof)  at the time it  became a Holder or any  subsequent  time it
became  a  Disqualified  Organization  all  payments  made  on  such  Residual
Certificate  at and after  either  such  times  (and all  costs and  expenses,
including  but  not  limited  to  attorneys'  fees,   incurred  in  connection
therewith).  Any  payment  (not  including  any such  costs and  expenses)  so
recovered by the Trustee  shall be paid and  delivered  to the last  preceding
Holder of such Residual Certificate.

         If any  purported  transferee  shall  become a  registered  Holder of a
Residual  Certificate  in violation of the  provisions of this Section  3.03(f),
then upon  receipt of written  notice to the Trustee  that the  registration  of
transfer of such Residual  Certificate was not in fact permitted by this Section
3.03(f), the last preceding Permitted Transferee shall be restored to all rights
as Holder thereof  retroactive to the date of such  registration  of transfer of
such Residual Certificate. The Trustee shall be under no liability to any Person
for any  registration of transfer of a Residual  Certificate that is in fact not
permitted  by  this  Section  3.03(f),  for  making  any  payment  due  on  such
Certificate to the registered Holder thereof or for taking any other action with
respect to such Holder  under the  provisions  of this  Agreement so long as the
transfer was registered upon receipt of the affidavit described in the preceding
paragraph of this Section 3.03(f).

          (g)  Each  Holder  of  a  Residual  Certificate,  by  such  Holder's
acceptance thereof,  shall be deemed for all purposes to have consented to the
provisions of this section.

          Section  3.04.   Cancellation  of   Certificates.   Any  Certificate
surrendered  for  registration  of transfer or exchange shall be cancelled and
retained  in  accordance  with  normal  retention  policies  with  respect  to
cancelled certificates maintained by the Trustee or the Certificate Registrar.

          Section 3.05. Replacement of Certificates. If (i) any Certificate is
mutilated and is  surrendered  to the Trustee or any  Authenticating  Agent or
(ii)  the  Trustee  or  any  Authenticating  Agent  receives  evidence  to its
satisfaction of the destruction,  loss or theft of any Certificate,  and there
is  delivered  to the  Trustee or the  Authenticating  Agent such  security or
indemnity as may be required by them to save each of them  harmless,  then, in
the absence of notice to the Depositor and any Authenticating  Agent that such
destroyed,  lost or  stolen  Certificate  has  been  acquired  by a bona  fide
purchaser,  the Trustee  shall  execute and the Trustee or any  Authenticating
Agent shall  authenticate and deliver,  in exchange for or in lieu of any such
mutilated,  destroyed,  lost or stolen Certificate,  a new Certificate of like
tenor  and  Certificate  Principal  Amount.  Upon  the  issuance  of  any  new
Certificate under this Section 3.05, the Trustee and Authenticating  Agent may
require the payment of a sum sufficient to cover any tax or other governmental
charge  that  may be  imposed  in  relation  thereto  and any  other  expenses
(including the fees and expenses of the Trustee or the  Authenticating  Agent)
connected  therewith.  Any  replacement  Certificate  issued  pursuant to this
Section 3.05 shall constitute complete and indefeasible  evidence of ownership
in the  applicable  Trust Fund,  as if originally  issued,  whether or not the
lost,  stolen or  destroyed  Certificate  shall be found at any time.  

          Section 3.06.  Persons Deemed  Owners.  Subject to the provisions of
Section 3.09 with  respect to  Book-Entry  Certificates,  the  Depositor,  the
Master Servicer,  the Trustee, the Certificate  Registrar and any agent of any
of them may treat the Person in whose name any  Certificate is registered upon
the books of the  Certificate  Registrar as the owner of such  Certificate for
the purpose of receiving  distributions pursuant to Sections 5.01 and 5.02 and
for all other  purposes  whatsoever,  and  neither the  Depositor,  the Master
Servicer,  the Trustee, the Certificate Registrar nor any agent of any of them
shall be affected by notice to the  contrary.  

          Section 3.07. Temporary Certificates. (a) Pending the preparation of
definitive  Certificates,  upon the order of the Depositor,  the Trustee shall
execute and shall  authenticate and deliver  temporary  Certificates  that are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any
authorized  denomination,   substantially  of  the  tenor  of  the  definitive
Certificates  in lieu of which they are issued and with such variations as the
authorized officers executing such Certificates may determine, as evidenced by
their  execution  of such  Certificates.  

          (b) If temporary  Certificates are issued,  the Depositor will cause
definitive  Certificates to be prepared without  unreasonable delay. After the
preparation of definitive  Certificates,  the temporary  Certificates shall be
exchangeable  for  definitive  Certificates  upon  surrender of the  temporary
Certificates  at the  office or agency of the  Trustee  without  charge to the
Holder.  Upon  surrender  for  cancellation  of  any  one  or  more  temporary
Certificates,  the  Trustee  shall  execute  and  authenticate  and deliver in
exchange therefor a like aggregate  Certificate Principal Amount of definitive
Certificates  of the same  Class  in the  authorized  denominations.  Until so
exchanged, the temporary Certificates shall in all respects be entitled to the
same  benefits  under this  Agreement as definitive  Certificates  of the same
Class.

          Section 3.08. Appointment of Paying Agent. The Trustee may appoint a
Paying   Agent   (which  may  be  the  Trustee)  for  the  purpose  of  making
distributions to  Certificateholders  hereunder.  The Trustee shall cause such
Paying Agent to execute and deliver to the Trustee an instrument in which such
Paying Agent shall agree with the Trustee that such Paying Agent will hold all
sums held by it for the payment to  Certificateholders  in an Eligible Account
in trust for the benefit of the Certificateholders entitled thereto until such
sums  shall  be paid to the  Certificateholders.  All  funds  remitted  by the
Trustee to any such Paying Agent for the purpose of making distributions shall
be paid to Certificateholders on each Distribution Date and any amounts not so
paid shall be returned on such Distribution Date to the Trustee. If the Paying
Agent is not the Trustee, the Trustee shall cause to be remitted to the Paying
Agent on or before the Business Day prior to each  Distribution  Date, by wire
transfer in immediately  available  funds, the funds to be distributed on such
Distribution Date. Any Paying Agent shall be either a bank or trust company or
otherwise authorized under law to exercise corporate trust powers.

          Section 3.09. Book-Entry Certificates.  (a) Each Class of Book-Entry
Certificates,  upon original  issuance,  shall be issued in the form of one or
more typewritten Certificates representing the Book-Entry Certificates,  to be
delivered to The Depository Trust Company, the initial Clearing Agency, by, or
on behalf of, the Depositor.  The Book-Entry  Certificates  shall initially be
registered  on the  Certificate  Register  in the name of the  nominee  of the
Clearing  Agency,   and  no  Certificate   Owner  will  receive  a  definitive
certificate  representing such Certificate  Owner's interest in the Book-Entry
Certificates,  except  as  provided  in  Section  3.09(c).  Unless  Definitive
Certificates have been issued to Certificate Owners of Book-Entry Certificates
pursuant to Section 3.09(c):  

                    (i) the  provisions  of this Section 3.09 shall be in full
          force and effect;

                    (ii) the Depositor, the Master Servicer, the Paying Agent,
          the Registrar and the Trustee may deal with the Clearing  Agency for
          all  purposes   (including  the  making  of   distributions  on  the
          Book-Entry  Certificates) as the authorized  representatives  of the
          Certificate  Owners and the Clearing Agency shall be responsible for
          crediting the amount of such  distributions  to the accounts of such
          Persons entitled  thereto,  in accordance with the Clearing Agency's
          normal procedures;

                    (iii) to the extent that the  provisions  of this  Section
          3.09  conflict  with any other  provisions  of this  Agreement,  the
          provisions of this Section 3.09 shall  control;  and 

                    (iv) the rights of  Certificate  Owners shall be exercised
          only   through  the  Clearing   Agency  and  the   Clearing   Agency
          Participants  and shall be limited to those  established  by law and
          agreements  between such Certificate  Owners and the Clearing Agency
          and/or the Clearing Agency Participants. Unless and until Definitive
          Certificates  are issued  pursuant to Section  3.09(c),  the initial
          Clearing  Agency will make  book-entry  transfers among the Clearing
          Agency  Participants  and  receive  and  transmit  distributions  of
          principal of and  interest on the  Book-Entry  Certificates  to such
          Clearing   Agency   Participants.   

          (b) Whenever notice or other communication to the Certificateholders
is required under this  Agreement,  unless and until  Definitive  Certificates
shall have been issued to Certificate Owners pursuant to Section 3.09(c),  the
Trustee shall give all such notices and communications  specified herein to be
given to Holders of the Book-Entry Certificates to the Clearing Agency.

          (c) If (i) (A) the Depositor advises the Trustee in writing that the
Clearing  Agency  is no  longer  willing  or able to  discharge  properly  its
responsibilities  with  respect to the  Book-Entry  Certificates,  and (B) the
Trustee or the Depositor is unable to locate a qualified  successor,  (ii) the
Depositor,  at its option,  advises  the Trustee in writing  that it elects to
terminate the book-entry system through the Clearing Agency or (iii) after the

                                  ARTICLE IV

                       ADMINISTRATION OF THE TRUST FUND

Series 1998-6." The Collection Account shall relate solely to the Certificates
issued by the Trust Fund hereunder, and funds in such Collection Account shall
not be commingled with any other monies.

Account into such new Collection Account.

          (c) The  Master  Servicer  will give to the  Trustee  prior  written
notice of the name and  address  of the  depository  institution  at which the
Collection  Account is maintained  and the account  number of such  Collection
Account. The Master Servicer shall take such actions as are necessary to cause
the depository institution holding the Collection Account to hold such account
in the name of the Trustee (subject to such Master  Servicer's right to direct
payments and investments  and its rights of withdrawal)  under this Agreement.
On the Deposit Date,  the entire amount on deposit in the  Collection  Account
(subject to permitted  withdrawals  set forth in Section 4.02),  including any
Prepayment Penalty Amounts on deposit in the Collection Account, but excluding
other  amounts not  included  in the  Available  Distribution  Amount for such
Distribution  Date pursuant to clauses (a) through (e) of paragraph (1) of the
definition  thereof,  shall be remitted  to the  Trustee for deposit  into the
Certificate  Account by wire  transfer in  immediately  available  funds.  The
Master Servicer,  at its option, may choose to make daily remittances from the
Collection  Account to the Trustee for deposit into the  Certificate  Account.

          (d) The Master  Servicer shall deposit or cause to be deposited into
the Collection  Account,  no later than the Business Day following the Closing
Date, any amounts  representing  Scheduled  Payments on the Mortgage Loans due
after the Cut-off  Date and  received by the Master  Servicer on or before the
Closing Date.  Thereafter,  the Master  Servicer  shall deposit or cause to be
deposited in the  Collection  Account on the  applicable  Remittance  Date the
following  amounts  received or payments  made by it (other than in respect of
principal of and  interest on the Mortgage  Loans due on or before the Cut-Off
Date):  

                    (i)  all  payments  on  account  of  principal,  including
          Principal  Prepayments,  late  collections  and  Prepayment  Penalty
          Amounts, on the Mortgage Loans;

                    (ii) all  payments on account of interest on the  Mortgage
          Loans (other than  payments due prior to the Cut-off  Date),  net of
          the Servicing Fee and Master Servicing Fee with respect to each such
          Mortgage Loan, but only to the extent of the amount  permitted to be
          withdrawn or withheld from the Collection Account in accordance with
          Sections  5.04 and 9.21;  

                    (iii)  any  unscheduled  payment  or other  recovery  with
          respect to a Mortgage Loan not otherwise specified in this paragraph
          (d),  including  all Net  Liquidation  Proceeds  with respect to the
          Mortgage  Loans  and REO  Property,  and  all  amounts  received  in
          connection with the operation of any REO Property, net of any unpaid
          Servicing  Fees and  Master  Servicing  Fees  with  respect  to such
          Mortgage Loans (but only to the extent of the amount permitted to be
          withdrawn or withheld from the Collection Account in accordance with
          Sections  5.04 and  9.21);  

                    (iv) all Insurance Proceeds;  

                    (v)  all  Advances  made  by the  Master  Servicer  or any
          Servicer  pursuant  to Section  5.04;  and 

                    (vi) all proceeds of any Mortgage Loan  repurchased by the
          Depositor,  the Seller, the Master Servicer or any other Person. 

          (e) Funds in the  Collection  Account  may be  invested  in Eligible
Investments  (selected by and at the written direction of the Master Servicer)
which shall  mature not later than the earlier of (a) the Deposit Date (except
that if such Eligible Investment is an obligation of the Trustee or the Paying
Agent, if other than the Trustee,  and such  Collection  Account is maintained
with the Trustee or the Paying  Agent,  if other than the  Trustee,  then such
Eligible  Investment shall mature not later than such applicable  Distribution
Date)  or (b) the day on  which  the  funds  in such  Collection  Account  are
required  to be remitted  to the  Trustee  for  deposit  into the  Certificate
Account,  and any such  Eligible  Investment  shall not be sold or disposed of
prior to its maturity. All such Eligible Investments shall be made in the name
of the Trustee (in its capacity as such) or its  nominee.  All income and gain
realized  from any such  investment  shall be for the  benefit  of the  Master
Servicer  and shall be subject to its  withdrawal  or order from time to time,
subject to Section 5.05,  and shall not be part of the Trust Fund.  The amount
of any losses incurred in respect of any such  investments  shall be deposited
in such  Collection  Account  by the  Master  Servicer  out of its own  funds,
without any right of  reimbursement  therefor,  immediately  as realized.  The
foregoing requirements for deposit in the Collection Account are exclusive, it
being  understood  and agreed that,  without  limiting the  generality  of the
foregoing,  payments  of  interest  on funds  in the  Collection  Account  and
payments in the nature of late payment  charges or assumption fees need not be
deposited by the Master Servicer in the Collection Account and may be retained
by the Master  Servicer or the  applicable  Servicer as  additional  servicing
compensation.  If the Master Servicer  deposits in the Collection  Account any
amount not required to be deposited therein,  it may at any time withdraw such
amount from such Collection Account.

          Section 4.02.  Application of Funds in the Collection  Account.  The
Master Servicer may, from time to time, make, or cause to be made, withdrawals
from the Collection Account for the following purposes:

                    (i) to reimburse  itself or any Servicer for Advances made
          by it or by such  Servicer  pursuant  to  Section  5.04;  the Master
          Servicer's  right to reimburse itself pursuant to this subclause (i)
          is  limited  to amounts  received  on or in  respect  of  particular
          Mortgage Loans (including,  for this purpose,  Liquidation  Proceeds
          and amounts  representing  Insurance  Proceeds  with  respect to the
          property  subject to the  related  Mortgage)  which  represent  late
          recoveries  (net of the  applicable  Servicing  Fee  and the  Master
          Servicing Fee) of payments of principal or interest respecting which
          any such Advance was made, it being  understood,  in the case of any
          such  reimbursement,  that the Master Servicer's or Servicer's right
          thereto shall be prior to the rights of the Certificateholders;

                    (ii) to reimburse itself or any Servicer for any Servicing
          Advances  made by it or by such  Servicer that it determines in good
          faith  will  not  be  recoverable  from  amounts  representing  late
          recoveries  of payments of  principal  or  interest  respecting  the
          particular Mortgage Loan as to which such Servicing Advance was made
          or from Liquidation  Proceeds or Insurance  Proceeds with respect to
          such  Mortgage  Loan, it being  understood,  in the case of any such
          reimbursement,  that such  Master  Servicer's  or  Servicer's  right
          thereto  shall  be prior to the  rights  of the  Certificateholders;

                    (iii) to reimburse  itself from  Liquidation  Proceeds for
          Liquidation  Expenses  and for  amounts  expended  by it pursuant to
          Sections  9.20 and  9.22(a)  in good  faith in  connection  with the
          restoration of damaged  property and, to the extent that Liquidation
          Proceeds  after  such  reimbursement  exceed  the  unpaid  principal
          balance of the related  Mortgage  Loan,  together  with  accrued and
          unpaid  interest  thereon at the  applicable  Mortgage Rate less the
          applicable  Servicing  Fee and the  Master  Servicing  Fee for  such
          Mortgage  Loan to the  Due  Date  next  succeeding  the  date of its
          receipt of such Liquidation  Proceeds,  to pay to itself out of such
          excess  the  amount of any  unpaid  assumption  fees,  late  payment
          charges or other Mortgagor  charges on the related Mortgage Loan and
          to retain any excess  remaining  thereafter as additional  servicing
          compensation,   it  being  understood,  in  the  case  of  any  such
          reimbursement or payment,  that such Master Servicer's or Servicer's
          right    thereto   shall   be   prior   to   the   rights   of   the
          Certificateholders;  

                    (iv) in the event it has  elected  not to pay  itself  the
          Master  Servicing  Fee out of any  Mortgagor  payment  on account of
          interest or other  recovery  with respect to a  particular  Mortgage
          Loan prior to the deposit of such  Mortgagor  payment or recovery in
          the Collection  Account,  to pay to itself the Master  Servicing Fee
          for each  Distribution Date and any unpaid Master Servicing Fees for
          prior Distribution  Dates, as reduced pursuant to Section 5.05, from
          any  Mortgagor  payment as to interest or such other  recovery  with
          respect to that Mortgage  Loan,  as is permitted by this  Agreement;

                    (v) to  reimburse  itself  or any  Servicer  for  expenses
          incurred  by  and  recoverable  by or  reimbursable  to  it or  such
          Servicer  pursuant to Section 9.04,  9.06,  9.16 or 9.22(a),  and to
          reimburse  itself for any  expenses  reimbursable  to it pursuant to
          Section  10.01(c);  

                    (vi) to pay to the  Depositor,  the  Seller,  the  Special
          Servicer or the Directing  Holder,  as  applicable,  with respect to
          each Mortgage Loan or REO Property  acquired in respect thereof that
          has been  repurchased by the Depositor  pursuant to this  Agreement,
          all  amounts  received  thereon and not  distributed  on the date on
          which  the  related  repurchase  was  effected,  and  to  pay to the
          applicable  Person  any  Advances  to the  extent  specified  in the
          definition of Purchase Price;  

                    (vii)  subject to Section  5.04,  to pay to itself  income
          earned  on the  investment  of  funds  deposited  in the  Collection
          Account; 

                    (viii) to make  payments to the  Trustee for deposit  into
          the  Certificate  Account in the amounts and in the manner  provided
          for in  Section  4.04;  

                    (ix) to make payment to itself and others  pursuant to any
          provision  of this  Agreement;  

                    (x) to withdraw funds deposited in error in the Collection
          Account; 

                    (xi)  to  clear  and  terminate  any  Collection   Account
          pursuant to Section  7.02;  

                    (xii) to reimburse a successor  Master Servicer (solely in
          its capacity as successor Master  Servicer),  for any fee or advance
          occasioned  by  a  termination  of  the  Master  Servicer,  and  the
          assumption  of such  duties by the  Trustee  or a  successor  Master
          Servicer  appointed by the Trustee pursuant to Section 6.14, in each
          case to the extent not reimbursed by the terminated Master Servicer,
          it  being  understood,  in the  case of any  such  reimbursement  or
          payment,  that  the  right of the  Master  Servicer  or the  Trustee
          thereto shall be prior to the rights of the Certificateholders;  and

                    (xiii) to  reimburse  any Servicer for such amounts as are
          due thereto under the  applicable  Servicing  Agreement and have not
          been retained by or paid to such Servicer to the extent  provided in
          the Servicing Agreement.

          In connection  with  withdrawals  pursuant to subclauses (i), (iii),
(iv) and (vi) above, the Master Servicer's or Servicer's  entitlement  thereto
is limited to  collections or other  recoveries on the related  Mortgage Loan.
The Master  Servicer shall  therefore keep and maintain a separate  accounting
for each  Mortgage Loan it master  services for the purpose of justifying  any
withdrawal from the Collection Account it maintains pursuant to such subclause
(i), (iii), (iv) and (vi).

          Section 4.04.  Certificate  Account. (a) The Trustee shall establish
and maintain in its name,  as trustee,  a special  deposit  trust account (the
"Certificate   Account"),  to  be  held  in  trust  for  the  benefit  of  the
Certificateholders  until  disbursed  pursuant to the terms of this Agreement.
The  Certificate  Account  shall  be an  Eligible  Account.  If  the  existing
Certificate  Account  ceases to be an  Eligible  Account,  the  Trustee  shall
establish a new  Certificate  Account  that is an Eligible  Account  within 20
Business Days and transfer all funds on deposit in such  existing  Certificate
Account into such new  Certificate  Account.  The  Certificate  Account  shall
relate  solely  to  the  Certificates   issued  hereunder  and  funds  in  the
Certificate  Account  shall be held  separate  and apart from and shall not be
commingled with any other monies including,  without limitation,  other monies
of the Trustee held under this Agreement.

          (b) The Trustee  shall cause to be  deposited  into the  Certificate
Account  on the day on  which,  or,  if such day is not a  Business  Day,  the
Business Day immediately  following the day on which,  any monies are remitted
by the Master  Servicer to the Trustee,  all such  amounts.  The Trustee shall
make withdrawals from the Certificate Account only for the following purposes:

                    (i) to  withdraw  amounts  deposited  in  the  Certificate
          Account in error;

                    (ii) to pay  itself  any  investment  income  earned  with
          respect to funds in the  Certificate  Account  invested  in Eligible
          Investments  as set  forth  in  subsection  (c)  below,  and to make
          payments  to itself and others  pursuant  to any  provision  of this
          Agreement;  

                    (iii) to make payments of the Master Servicing Fee (to the
          extent not already withheld or withdrawn from the Collection Account
          by the Master Servicer) to the Master Servicer;

                    (iv)  to  make  distributions  to  the  Certificateholders
          pursuant to Article V; and

                    (v)  to  clear  and  terminate  the  Certificate   Account
          pursuant to Section 7.02.

          (c) The Trustee shall invest, or cause to be invested, funds held in
the Certificate  Account in Eligible  Investments (which may be obligations of
the  Trustee).  All  such  investments  must  mature  no  later  than the next
Distribution  Date,  and  shall  not be sold or  disposed  of  prior  to their
maturity.  All  such  Eligible  Investments  will be  made in the  name of the
Trustee (in its capacity as such) or its nominee. All income and gain realized
from any such investment  shall be  compensation  for the Trustee and shall be
subject to its withdrawal on order from time to time. The amount of any losses
incurred in respect of any such  investments  shall be paid by the Trustee for
deposit in the Certificate Account out of its own funds,  without any right of
reimbursement therefor, immediately as realized.

                   DISTRIBUTIONS TO HOLDERS OF CERTIFICATES

          Section 5.01.  Distributions  Generally. (a) Subject to Section 7.01
respecting the final  distribution on the  Certificates,  on each Distribution
Date the Trustee or the Paying Agent shall make  distributions  in  accordance
with this Article V. Such distributions  shall be made by check mailed to each
Certificateholder's  address as it appears on the Certificate  Register of the
Certificate  Registrar (which shall initially be the Trustee) or, upon written
request made to the Trustee at least three  Business Days prior to the related
Distribution  Date  to  any  Certificateholder  owning  an  aggregate  initial
Certificate  Principal  Amount  of at least  $2,500,000,  or, in the case of a
Class AX1 Certificate, a Percentage Interest of at least 50%, and, in the case
of the Class AX2 Certificate,  a Percentage Interest of 100%, by wire transfer
in immediately  available funds to an account  specified in the request and at
the  expense  of such  Certificateholder;  provided,  however,  that the final
distribution  in  respect  of  any   Certificate   shall  be  made  only  upon
presentation  and surrender of such Certificate at the Corporate Trust Office.
Wire transfers will be made at the expense of the Holder  requesting such wire
transfer by  deducting  a wire  transfer  fee from the  related  distribution.
Notwithstanding  such final  payment of principal of any of the  Certificates,
the Residual  Certificates  will remain  outstanding  until the termination of
each REMIC and the payment in full of all other  amounts  due with  respect to
the Residual Certificates and at such time such final payment in retirement of
any Residual Certificates will be made only upon presentation and surrender of
such Certificate at the Corporate Trust Office of the Trustee or at the office
of the New York Presenting  Agent.  If any payment  required to be made on the
Certificates  is to be made on a day that is not a  Business  Day,  then  such
payment will be made on the next succeeding Business Day.

          (b)  All   distributions   or  allocations   made  with  respect  to
Certificateholders  within  each  Class  on each  Distribution  Date  shall be
allocated  among  the  outstanding  Certificates  in  such  Class  equally  in
proportion to their respective initial Class Certificate Principal Amounts (or
initial Notional Amounts).

          Section 5.02.  Distributions  from the Certificate  Account.  (a) On
each  Distribution  Date the  Trustee  (or the  Paying  Agent on behalf of the

          (determined on the basis of Accrued  Certificate  Interest otherwise
          distributable thereon) of any Net Prepayment Interest Shortfalls for
          such Distribution Date; provided,  however, that Accrued Certificate
          Interest on the Class A2  Certificates  for such  Distribution  Date
          shall  be  applied  in the  manner  set  forth in  Section  5.02(f),
          provided,  further, that any shortfall in available amounts shall be
          allocated  among such Classes in proportion to the amount of Accrued
          Certificate  Interest  (as  so  reduced)  that  would  otherwise  be
          distributable  thereon (or added to the Certificate Principal Amount
          thereof); 

                    (iii) from the remaining Available Distribution Amount, to
          each Class of Senior  Certificates,  any related Interest  Shortfall

          Shortfall for the Class A2 Certificates for such  Distribution  Date
          shall  be  applied  in  the  manner  provided  by  Section  5.02(f),
          provided,  further, that any shortfall in available amounts shall be

(iii) of the definition of Subordinate  Principal  Distribution Amount will be
made in  respect  of the Class B2,  Class B3,  Class B4,  Class B5 or Class B6

          (d)  Notwithstanding  Section 5.02(a),  on each  Distribution  Date,
amounts  otherwise  distributable  to the Class AX2  Certificates  pursuant to
Sections  5.02(a)(ii) and (iii) shall be withheld by the Trustee and deposited
into an Eligible  Account  established  by the Depositor and maintained by the
Trustee  entitled  "Structured  Asset  Securities  Corporation  Series  1998-6
Reserve Fund" (the "Reserve  Fund").  On each  Distribution  Date,  amounts on
deposit in the Reserve  Fund shall be  withdrawn by the Trustee and applied to
pay the  Special  Servicer  the Special  Servicing  Fee and  Extended  Special
Servicing  Fee due and unpaid with  respect to such  Distribution  Date or any
previous  Distribution  Date. On any Distribution  Date, amounts on deposit in
the Reserve Fund (after payment of any due and unpaid  Special  Servicing Fees
and Extended Special Servicing Fees) in excess of the Reserve Fund Requirement
shall be released to the Class AX2  Certificateholder and thereafter shall not
be subject to return by the Class AX2  Certificateholder  or otherwise pledged
to the Trust Fund for the payment of fees to the  Special  Servicer or for any
other purpose.

          The Reserve  Fund will not be part of the REMIC and, for all federal
income  tax   purposes,   will  be   beneficially   owned  by  the  Class  AX2
Certificateholder.  Amounts on deposit in the Reserve  Fund may be invested by
the Trustee in Eligible  Investments (which may be obligations of the Trustee)
at the written  direction of the Class AX2  Certificateholder,  provided  such
investments  mature no later than the next Distribution Date, and shall not be
sold or disposed of prior to their  maturity.  All such  Eligible  Investments
will be made in the name of the Class AX2  Certificateholder.  All  income and
gain from any such investment shall belong to the Class AX2  Certificateholder
and shall be subject to its  withdrawal on order from time to time. The amount
of any losses incurred in respect of any such investments shall be paid by the
Class AX2  Certificateholder  for deposit into the Reserve Fund out of its own
funds, without any right of reimbursement therefor, immediately as realized.

          (e) On each  Distribution  Date, the Trustee shall distribute to the
holder of the Class R Certificate any remaining Available  Distribution Amount
for such  Distribution  Date after  application  of all amounts  described  in
paragraph  (a) of this Section  5.02.  Any  distributions  made to the Class R
Certificateholder  pursuant to this  paragraph  (e) shall not reduce the Class
Certificate Principal Amount of the Class R Certificate.  In addition, on each
Distribution  Date, the Trustee shall  distribute to the Holder of the Class R
Certificate  any  Prepayment  Penalty  Amounts  received  during  the  related
Prepayment Period.

          (f) On each  Distribution  Date through the Credit Support Depletion
Date, the amounts allocable to the Class A2 Certificates on such date pursuant
to  clauses   (a)(ii)  and   (a)(iii)  of  this  Section  5.02  shall  not  be
distributable  as interest thereon but shall instead be (i) added to the Class
Certificate  Principal Amount thereof and distributed to the following Classes
of Certificates,  before any distributions are made pursuant to clause (a)(iv)
of this Section 5.02, in the following order of priority:

          first,  to the  Class A1  Certificates,  in  reduction  of the Class
Certificate  Principal Amount thereof,  until the Class Certificate  Principal
Amount thereof has been reduced to zero.

          second,  to the Class A2  Certificates,  in  reduction  of the Class
Certificate  Principal Amount thereof,  until the Class Certificate  Principal
Amount thereof has been reduced to zero.

          On  each  Distribution  Date  occurring  after  the  Credit  Support
Depletion Date,  amounts  allocable to the Class A2  Certificates  pursuant to
clauses  (a)(ii) and (a)(iii) of this Section 5.02 shall be  distributable  on
such  Distribution  Date  pursuant to such  clauses to Holders of the Class A2
Certificates  as Accrued  Certificate  Interest  and shall not be added to the
Class Certificate Principal Amount thereof.

          Section 5.03. Allocation of Realized Losses. (a) On any Distribution
Date, the principal portion of each Realized Loss (other than any Excess Loss)
in respect of a Mortgage  Loan shall be  allocated in the  following  order of

                    Class of Accrual  Certificates shall be allocated (subject
                    to Section  5.03(c)) on the basis of the lesser of (x) the
                    Class  Certificate  Principal  Amount thereof  immediately
                    prior  to the  applicable  Distribution  Date  and (y) the
                    Class  Certificate  Principal  thereof on the Closing Date
                    (as reduced by any Realized  Losses  previously  allocated
                    thereto).

          (b) With respect to any Distribution  Date, the principal portion of
any Excess  Loss in respect of a Mortgage  Loan shall be  allocated  among the
Classes of Certificates,  pro rata, based on the respective Class  Certificate
Principal Amounts thereof; provided, that any such loss allocated to any Class
of  Accrual  Certificates  (and any  Accrual  Component)  shall  be  allocated

Certificate  Principal  Amount  thereof  immediately  prior to the  applicable
Distribution  Date and (y) the Class  Certificate  Principal Amount thereof on
the  Closing  Date (as reduced by any  Realized  Losses  previously  allocated

          (c)  Any  Realized  Losses  allocated  to a  Class  of  Certificates
pursuant to Section 5.03(a) or (b) shall be allocated  among the  Certificates
of such Class in proportion to their respective Certificate Principal Amounts.
Any  allocation  of Realized  Losses  pursuant to this  paragraph (c) shall be
accomplished  by  reducing  the  Certificate  Principal  Amount of the related
Certificates  on the related  Distribution  Date in  accordance  with  Section
5.03(d).  

          (d) Realized  Losses  allocated in accordance with this Section 5.03
shall be allocated on the  Distribution  Date in the month following the month
in which such loss was  incurred  and,  in the case of the  principal  portion
thereof,  after giving effect to distributions made on such Distribution Date.

          (e) On each Distribution Date, the Subordinate Certificate Writedown
Amount for such date shall effect a corresponding reduction in the Certificate
Principal  Amount  of the  lowest  ranking  Class of  outstanding  Subordinate
Certificates,  which  reduction  shall occur on such  Distribution  Date after
giving effect to  distributions  made on such  Distribution  Date.  

          (f) In the event that there is a recovery of an amount in respect of
principal of a Mortgage Loan,  which amount had previously been allocated as a
Realized Loss to one or more Classes of Certificates,  each outstanding  Class
to which any portion of such Realized Loss had previously been allocated shall
be entitled to receive,  on the  Distribution  Date in the month following the
month in which such  recovery is  received,  its pro rata share  (based on the
Class Certificate Principal Amount thereof) of such recovery, up to the amount
of the portion of such Realized Loss  previously  allocated to such Class.  In
the  event  that the total  amount  of such  recovery  exceeds  the  amount of
Realized Loss  allocated to the  outstanding  Classes in  accordance  with the
preceding provisions, each outstanding Class of Certificates shall be entitled
to receive its pro rata share of the amount of such  excess,  up to the amount
of any unrecovered  Realized Loss previously allocated to such Class. Any such
recovery  allocated to a Class of  Certificates  shall not further  reduce the
Certificate  Principal  Amount  of such  Certificate.  Any  such  amounts  not
otherwise allocated to any Class of Certificates,  pursuant to this subsection
shall be treated as Principal Prepayments for purposes of this Agreement.

          Section 5.04. Advances by Master Servicer and Trustee.  (a) Advances
shall be made in respect of each Deposit Date as provided  herein.  If, on any
Determination Date, the Master Servicer determines that any Scheduled Payments
due during the related Due Period (other than Balloon  Payments) have not been
received,  the Master  Servicer  shall,  or cause the applicable  Servicer to,
advance  such  amount,  less an amount,  if any,  which if advanced the Master
Servicer or the applicable  Servicer has  determined  would not be recoverable
from amounts  received  with respect to such  Mortgage  Loan,  including  late
payments, Liquidation Proceeds, Insurance Proceeds or otherwise. If the Master
Servicer determines that an Advance is required,  it shall on the Deposit Date
immediately  following such Determination Date either (i) remit to the Trustee
from its own funds (or funds advanced by the applicable  Servicer) for deposit
in the Certificate  Account an amount equal to such Advance,  (ii) cause to be
made an appropriate entry in the records of the Collection  Account that funds
in such account being held for future distribution or withdrawal have been, as
permitted  by this  Section  5.04,  used by the Master  Servicer  to make such
Advance,  and remit such funds to the Trustee  for deposit in the  Certificate
Account or (iii) make Advances in the form of any  combination  of clauses (i)
and (ii)  aggregating the amount of such Advance.  Any funds being held in the
Collection Account for future distribution to  Certificateholders  and so used
shall be replaced by the Master  Servicer  from its own funds by remittance to
the  Trustee for  deposit in the  Certificate  Account on or before any future
Deposit  Date to the  extent  that  funds in the  Certificate  Account on such
Deposit Date shall be less than payments to Certificateholders  required to be
made on the related  Distribution  Date. The Master Servicer and each Servicer
shall be  entitled  to be  reimbursed  from  the  Collection  Account  for all
Advances made by it as provided in Section 4.02.

          (b) In the event  that the Master  Servicer  fails for any reason to
make an Advance  required to be made pursuant to Section 5.04 on or before the
Deposit Date, the Trustee shall, on or before the related  Distribution  Date,
deposit  in the  Certificate  Account  an  amount  equal to the  excess of (a)
Advances required to be made by the Master Servicer or any Servicer that would
have been  deposited  in such  Certificate  Account over (b) the amount of any
Advance  made by the Master  Servicer  or any  Servicer  with  respect to such
Distribution Date;  provided,  however,  that the Trustee shall be required to
make such Advance only if it is not prohibited by law from doing so and it has
determined that such Advance would be recoverable  from amounts to be received
with respect to such  Mortgage  Loan,  including  late  payments,  Liquidation
Proceeds,  Insurance Proceeds, or otherwise.  The Trustee shall be entitled to
be reimbursed from the Certificate Account for Advances made by it pursuant to
this Section 5.04 as if it were the Master Servicer.

          Section 5.05. Compensating  Interest  Payments.  The amount of
the Aggregate Master Servicing  Compensation payable to the Master Servicer in
respect  of any  Distribution  Date  shall be  reduced  by the  amount  of any
Compensating  Interest  Payment for such  Distribution  Date,  but only to the
extent such  Compensating  Interest Payment is not actually made by a Servicer
on the  applicable  Remittance  Date.  Such amount  shall not be treated as an
Advance and shall not be reimbursable to the Master Servicer.

                                  ARTICLE VI

                   CONCERNING THE TRUSTEE; EVENTS OF DEFAULT

          Section 6.01. Duties of Trustee. (a) The Trustee,  except during the
continuance of an Event of Default, undertakes to perform such duties and only
such duties as are  specifically  set forth in this Agreement.  Any permissive
right of the Trustee  provided for in this Agreement shall not be construed as
a duty of the  Trustee.  If an  Event  of  Default  has  occurred  and has not
otherwise been cured or waived,  the Trustee shall exercise such of the rights
and powers vested in it by this  Agreement and use the same degree of care and
skill in their  exercise as a prudent  Person would  exercise or use under the
circumstances  in the conduct of such Person's own affairs  unless the Trustee
is acting as Master  Servicer,  in which case it shall use the same  degree of
care and skill as the Master Servicer hereunder.

          (b) The  Trustee,  upon  receipt of all  resolutions,  certificates,
statements,   opinions,   reports,  documents,  orders  or  other  instruments
furnished  to the Trustee  which are  specifically  required  to be  furnished
pursuant to any provision of this  Agreement,  shall examine them to determine
whether they are in the form required by this  Agreement;  provided,  however,
that the Trustee shall not be  responsible  for the accuracy or content of any
such resolution,  certificate,  statement, opinion, report, document, order or
other instrument furnished by the Master Servicer,  to the Trustee pursuant to
this Agreement.

          (c) The Trustee  shall not have any  liability  arising out of or in
connection  with  this  Agreement,   except  for  its  negligence  or  willful
misconduct.  No provision of this Agreement  shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct; provided, however, that: 

                    (i)  The  Trustee  shall  not be  personally  liable  with
          respect to any action  taken,  suffered or omitted to be taken by it
          in good faith in accordance with the consent or direction of Holders
          of Certificates as provided in Section 6.19 hereof;

                    (ii) For all purposes  under this  Agreement,  the Trustee
          shall not be deemed to have  notice of any Event of  Default  (other
          than  resulting  from a failure by the Master  Servicer (i) to remit
          funds (or to make  Advances) or (ii) to furnish  information  to the
          Trustee when required to do so) unless a Responsible  Officer of the
          Trustee has actual knowledge thereof or unless written notice of any
          event  which is in fact such a default is received by the Trustee at
          the Corporate Trust Office,  and such notice  references the Holders
          of the Certificates  and this Agreement;  

                    (iii) No provision  of this  Agreement  shall  require the
          Trustee  to  expend  or risk its own  funds or  otherwise  incur any
          financial  liability  in  the  performance  of  any  of  its  duties
          hereunder,  or in the exercise of any of its rights or powers, if it
          shall have  reasonable  grounds for believing that repayment of such
          funds or adequate  indemnity  against  such risk or liability is not
          reasonably  assured to it; 

                    (iv) The Trustee shall not be  responsible  for any act or
          omission of the Master  Servicer;  and 

                    (v) The  Trustee  shall not be  personally  liable for any
          error of judgement  made in good faith by a  Responsible  Officer of
          the Trustee unless it shall be proved that the Trustee was negligent
          in ascertaining or investigating the facts related thereto.

          (d) The Trustee  shall have no duty  hereunder  with  respect to any
complaint, claim, demand, notice or other document it may receive or which may
be alleged to have been  delivered  to or served  upon it by the  parties as a
consequence  of the  assignment  of any  Mortgage  Loan  hereunder;  provided,
however,  that the Trustee  shall use its best  efforts to remit to the Master
Servicer  upon  receipt any such  complaint,  claim,  demand,  notice or other
document (i) which is delivered to the Corporate  Trust Office of the Trustee,
(ii) of which a  Responsible  Officer  has actual  knowledge,  and (iii) which
contains information  sufficient to permit the Trustee to make a determination
that the real property to which such document relates is a Mortgaged Property.

          (e) The Trustee shall not be  personally  liable with respect to any
action  taken,  suffered  or  omitted  to be  taken  by it in  good  faith  in
accordance  with the  direction  of  Certificateholders  of any Class  holding
Certificates  which  evidence,   as  to  such  Class,   Percentage   Interests
aggregating  not less than 25% as to the time,  method and place of conducting
any  proceeding  for any remedy  available to the Trustee,  or exercising  any
trust or power  conferred  upon the  Trustee,  under this  Agreement.  

          (f) The Trustee  shall pay, out of its own funds,  any fees assessed
by the Rating Agency after the Closing Date in connection with maintaining the
ratings of the  Certificates.  

          (g) The  Trustee  shall  not be  required  to expend or risk its own
funds or otherwise incur financial  liability in the performance of any of its
duties hereunder,  or in the exercise of any of its rights or powers, if there
is  reasonable  ground  for  believing  that the  repayment  of such  funds or
adequate indemnity against such risk or liability is not reasonably assured to
it, and none of the provisions  contained in this Agreement shall in any event
require  the  Trustee  to  perform,  or  be  responsible  for  the  manner  of
performance  of, any of the  obligations of the  Depositor,  the Seller or the
Master Servicer under this Agreement,  except during such time, if any, as the
Trustee  shall be the  successor  to, and be vested with the  rights,  duties,
powers and privileges of, the Master  Servicer in accordance with the terms of
this Agreement.  

          Section  6.02.  Certain  Matters  Affecting  the Trustee.  Except as
otherwise provided in Section 6.01:

                    (i) The  Trustee  may  request,  and may rely and shall be
          protected in acting or refraining  from acting upon any  resolution,
          Officer's   Certificate,   certificate  of  auditors  or  any  other
          certificate,   statement,   instrument,   opinion,  report,  notice,
          request,  consent,  order, approval, bond or other paper or document
          believed by it to be genuine and to have been signed or presented by
          the proper party or parties;

                    (ii) The Trustee may consult  with  counsel and any advice
          of its  counsel or Opinion  of  Counsel  shall be full and  complete
          authorization  and  protection  in respect  of any  action  taken or
          suffered or omitted by it hereunder in good faith and in  accordance
          with such advice or Opinion of Counsel;  

                    (iii) The Trustee shall not be  personally  liable for any
          action taken, suffered or omitted by it in good faith and reasonably
          believed by it to be authorized  or within the  discretion or rights
          or powers conferred upon it by this Agreement;  

                    (iv) Unless an Event of Default shall have occurred and be
          continuing, the Trustee shall not be bound to make any investigation
          into the facts or  matters  stated in any  resolution,  certificate,
          statement,  instrument,  opinion, report, notice, request,  consent,
          order, approval,  bond or other paper or document (provided the same
          appears regular on its face),  unless  requested in writing to do so
          by  Holders of at least a majority  in Class  Certificate  Principal
          Amount (or Aggregate Notional Amount) of each Class of Certificates;
          provided,  however, that, if the payment within a reasonable time to
          the  Trustee  of the costs,  expenses  or  liabilities  likely to be
          incurred  by it in the  making  of  such  investigation  is,  in the
          opinion of the Trustee, not reasonably assured to the Trustee by the
          security afforded to it by the terms of this Agreement,  the Trustee
          may require  reasonable  indemnity against such expense or liability
          or payment of such estimated  expenses as a condition to proceeding.
          The  reasonable  expense  thereof  shall  be  paid  by  the  Holders
          requesting such  investigation;  and 

                    (v) The  Trustee  may  execute any of the trusts or powers
          hereunder or perform any duties  hereunder  either directly or by or
          through  agents or attorneys,  which agents or attorneys  shall have
          any or all of the  rights,  powers,  duties and  obligations  of the
          Trustee  conferred  on them by such  appointment  provided  that the
          Trustee  shall  continue  to  be  responsible  for  its  duties  and
          obligations  hereunder.  

          Section 6.03. Trustee Not Liable for Certificates or Mortgage Loans.
The Trustee makes no representations as to the validity or sufficiency of this
Agreement or of the Certificates (other than the certificate of authentication
on the  Certificates)  or of any Mortgage Loan, or related  document save that
the Trustee represents that,  assuming due execution and delivery by the other
parties  hereto,  this  Agreement  has  been  duly  authorized,  executed  and
delivered by it and constitutes its valid and binding obligation,  enforceable
against it in accordance with its terms except that such enforceability may be
subject to (A) applicable  bankruptcy  and  insolvency  laws and other similar
laws affecting the enforcement of the rights of creditors  generally,  and (B)
general  principles  of equity  regardless  of  whether  such  enforcement  is
considered  in a  proceeding  in equity or at law.  The  Trustee  shall not be
accountable  for the use or  application by the Depositor of funds paid to the
Depositor in  consideration  of the  assignment  of the Mortgage  Loans to the
Trust  Fund  by the  Depositor  or for  the use or  application  of any  funds
deposited into the Collection  Account,  the Certificate  Account,  any Escrow
Account  or  any  other  fund  or  account  maintained  with  respect  to  the
Certificates.  

          Section  6.04.  Trustee  May Own  Certificates.  The Trustee and any
Affiliate or agent of the Trustee in its  individual or any other capacity may
become the owner or pledgee of Certificates and may transact banking and trust
with the other  parties  hereto  with the same rights it would have if it were
not Trustee or such agent.

          Section  6.05.  Eligibility  Requirements  for Trustee.  The Trustee
hereunder  shall at all times be (i) an  institution  insured  by the FDIC and
(ii) a  corporation  or  national  banking  association,  organized  and doing
business  under  the  laws of any  State  or the  United  States  of  America,
authorized  under  such laws to  exercise  corporate  trust  powers,  having a
combined  capital  and  surplus of not less than  $50,000,000  and  subject to
supervision or examination by federal or state authority.  If such corporation
or  national  banking  association  publishes  reports of  condition  at least
annually,  pursuant to law or to the requirements of the aforesaid supervising
or examining  authority,  then, for the purposes of this Section, the combined
capital and surplus of such corporation or national banking  association shall
be deemed to be its  combined  capital  and  surplus  as set forth in its most
recent report of condition so published. In case at any time the Trustee shall
cease to be  eligible in  accordance  with  provisions  of this  Section,  the
Trustee shall resign  immediately in the manner and with the effect  specified
in Section 6.06.  

          Section 6.06.  Resignation  and Removal of Trustee.  (a) The Trustee
may at any time  resign and be  discharged  from the trust  hereby  created by
giving written notice thereof to the Depositor and the Master  Servicer.  Upon
receiving such notice of  resignation,  the Depositor will promptly  appoint a
successor trustee by written instrument, one copy of which instrument shall be
delivered to the resigning Trustee,  one copy to the successor trustee and one
copy to the  Master  Servicer.  If no  successor  trustee  shall  have been so
appointed and shall have accepted  appointment within 30 days after the giving
of such notice of resignation, the resigning Trustee may petition any court of
competent  jurisdiction for the appointment of a successor trustee.  

          (b) If at any time (i) the  Trustee  shall  cease to be  eligible in
accordance  with the provisions of Section 6.05 and shall fail to resign after
written  request  therefor by the  Depositor,  (ii) the Trustee  shall  become
incapable  of  acting,  or shall be  adjudged a bankrupt  or  insolvent,  or a
receiver of the Trustee or of its property  shall be appointed,  or any public
officer  shall take  charge or control of the  Trustee or of its  property  or
affairs for the purpose of rehabilitation,  conservation or liquidation, (iii)
a tax is imposed or threatened  with respect to the Trust Fund by any state in
which the Trustee or the Trust Fund held by the  Trustee is  located,  or (iv)
the continued  use of the Trustee would result in a downgrading  of the rating
by the  Rating  Agency of any Class of  Certificates  with a rating,  then the
Depositor  may remove the Trustee  and appoint a successor  trustee by written
instrument,  one copy of which instrument shall be delivered to the Trustee so
removed,  one  copy  to the  successor  trustee  and one  copy  to the  Master
Servicer.

          (c) The Holders of more than 50% of the Class Certificate  Principal
Amount (or Aggregate Notional Amount) of each Class of Certificates may at any
time upon 30 days' written  notice to the Trustee and to the Depositor  remove
the  Trustee  by such  written  instrument,  signed by such  Holders  or their
attorney-in-fact  duly  authorized,  one  copy of  which  instrument  shall be
delivered to the Depositor, one copy to the Trustee so removed and one copy to
the Master  Servicer;  the Depositor  shall  thereupon use its best efforts to
appoint a  mutually  acceptable  successor  trustee  in  accordance  with this
Section.  

          (d) Any  resignation or removal of the Trustee and  appointment of a
successor  trustee  pursuant to any of the  provisions  of this Section  shall
become  effective upon  acceptance of appointment by the successor  trustee as
provided in Section  6.07.  

          Section 6.07. Successor Trustee. (a) Any successor trustee appointed
as  provided in Section  6.06 shall  execute,  acknowledge  and deliver to the
Depositor,  the Master Servicer and to its  predecessor  trustee an instrument
accepting such appointment hereunder, and thereupon the resignation or removal
of the predecessor  trustee shall become effective and such successor trustee,
without any further act,  deed or  conveyance,  shall become fully vested with
all the rights,  powers, duties and obligations of its predecessor  hereunder,
with like effect as if originally  named as trustee  herein.  The  predecessor
trustee  shall  deliver  to the  successor  trustee  all  Mortgage  Files  and
documents and statements  related to each Mortgage Files held by it hereunder,
and shall duly assign, transfer, deliver and pay over to the successor trustee
the entire Trust Fund, together with all necessary instruments of transfer and
assignment  or other  documents  properly  executed  necessary  to effect such
transfer  and  such  of  the  record  or  copies  thereof  maintained  by  the
predecessor  trustee in the  administration  hereof as may be requested by the
successor  trustee  and shall  thereupon  be  discharged  from all  duties and
responsibilities  under this Agreement.  In addition,  the Master Servicer and
the predecessor  trustee shall execute and deliver such other  instruments and
do such other things as may reasonably be required to more fully and certainly
vest and confirm in the successor trustee all such rights,  powers, duties and
obligations.

          (b) No successor  trustee  shall accept  appointment  as provided in
this Section unless at the time of such  appointment  such  successor  trustee
shall be eligible under the provisions of Section 6.05.

          (c)  Upon  acceptance  of  appointment  by a  successor  trustee  as
provided  in this  Section,  the  Master  Servicer  shall  mail  notice of the
succession of such trustee  hereunder to all Holders of  Certificates at their
addresses as shown in the Certificate Register and to the Rating Agencies. The
expenses of such mailing shall be borne by the Master Servicer.

          Section 6.08.  Merger or Consolidation  of Trustee.  Any Person into
which the Trustee may be merged or with which it may be  consolidated,  or any
Person  resulting from any merger,  conversion or  consolidation  to which the
Trustee  shall be a party,  or any Persons  succeeding  to the business of the
Trustee,  shall  be  the  successor  to the  Trustee  hereunder,  without  the
execution  or filing of any paper or any further act on the part of any of the
parties hereto, anything herein to the contrary notwithstanding, provided that
such Person shall be eligible under the provisions of Section 6.05.

          Section  6.09.  Appointment  of  Co-Trustee,   Separate  Trustee  or
Custodian.  (a)  Notwithstanding any other provisions hereof, at any time, the
Trustee, the Depositor or the  Certificateholders  evidencing more than 50% of
the Class Certificate  Principal Amount (or Aggregate Notional Amount) of each
Class of  Certificates  shall each have the power from time to time to appoint
one or more Persons to act either as co-trustees  jointly with the Trustee, or
as separate trustees,  or as custodians,  for the purpose of holding title to,
foreclosing  or otherwise  taking  action with  respect to any  Mortgage  Loan
outside the state where the Trustee has its principal  place of business where
such separate  trustee or co-trustee is necessary or advisable (or the Trustee
has been  advised  by the  Master  Servicer  that  such  separate  trustee  or
co-trustee is necessary or  advisable)  under the laws of any state in which a
property  securing a Mortgage  Loan is located or for the purpose of otherwise
conforming to any legal requirement,  restriction or condition in any state in
which a property  securing a Mortgage Loan is located or in any state in which
any portion of the Trust Fund is located. The separate Trustees,  co-trustees,
or custodians so appointed  shall be trustees or custodians for the benefit of
all the  Certificateholders and shall have such powers, rights and remedies as
shall be specified in the instrument of appointment;  provided,  however, that
no such appointment  shall, or shall be deemed to, constitute the appointee an
agent of the Trustee.  The obligation of the Trustee to make Advances pursuant
to Section  5.04 and 6.14  hereof  shall not be  affected  or  assigned by the
appointment  of a co-trustee.  

          (b) Every separate trustee,  co-trustee, and custodian shall, to the
extent  permitted  by law,  be  appointed  and act  subject  to the  following
provisions and conditions:

                    (i) all powers,  duties,  obligations and rights conferred
          upon the Trustee in respect of the  receipt,  custody and payment of
          moneys shall be exercised solely by the Trustee;

                    (ii) all other  rights,  powers,  duties  and  obligations
          conferred or imposed upon the Trustee  shall be conferred or imposed
          upon and  exercised or  performed  by the Trustee and such  separate
          trustee, co-trustee, or custodian jointly, except to the extent that
          under any law of any  jurisdiction  in which any  particular  act or
          acts  are to be  performed  the  Trustee  shall  be  incompetent  or
          unqualified to perform such act or acts, in which event such rights,
          powers,  duties and  obligations,  including the holding of title to
          the Trust  Fund or any  portion  thereof  in any such  jurisdiction,
          shall  be  exercised  and   performed  by  such  separate   trustee,
          co-trustee,  or custodian;  

                    (iii)  no  trustee  or   custodian   hereunder   shall  be
          personally  liable  by reason  of any act or  omission  of any other
          trustee  or  custodian  hereunder;  and  

                    (iv) the Trustee or the Certificateholders evidencing more
          than 50% of the Aggregate  Voting  Interests of the Certificates may
          at any  time  accept  the  resignation  of or  remove  any  separate
          trustee,  co-trustee  or  custodian,  so appointed by it or them, if
          such resignation or removal does not violate the other terms of this
          Agreement.  

          (c) Any notice,  request or other writing given to the Trustee shall
be  deemed  to have  been  given to each of the  then  separate  trustees  and
co-trustees,  as  effectively  as if given to each of them.  Every  instrument
appointing any separate  trustee,  co-trustee or custodian shall refer to this
Agreement and the  conditions  of this Article VI. Each  separate  trustee and
co-trustee,  upon its acceptance of the trusts conferred, shall be vested with
the estates or property  specified in its  instrument of  appointment,  either
jointly with the Trustee or separately, as may be provided therein, subject to
all the provisions of this Agreement,  specifically  including every provision
of this Agreement  relating to the conduct of,  affecting the liability of, or
affording  protection to, the Trustee.  Every such  instrument  shall be filed
with the Trustee.

          (d) Any separate trustee,  co-trustee or custodian may, at any time,
constitute  the  Trustee  its agent or  attorney-in-fact  with full  power and
authority,  to the extent not prohibited by law, to do any lawful act under or
in respect of this  Agreement  on its behalf and in its name.  If any separate
trustee, co-trustee or custodian shall die, become incapable of acting, resign
or be removed,  all of its estates,  properties,  rights,  remedies and trusts
shall vest in and be exercised by the Trustee, to the extent permitted by law,
without  the  appointment  of a new or  successor  trustee.  

          (e) No separate trustee,  co-trustee or custodian hereunder shall be
required to meet the terms of eligibility as a successor trustee under Section
6.05 hereunder and no notice to Certificateholders of the appointment shall be
required  under  Section 6.07 hereof.  

          (f) The Trustee agrees to instruct the  co-trustees,  if any, to the
extent  necessary  to fulfill the  Trustee's  obligations  hereunder.  

          (g)  The  Trustee  shall  pay  the  reasonable  compensation  of the
co-trustees to the extent, and in accordance with the standards,  specified in
Section  6.12 hereof  (which  compensation  shall not reduce any  compensation
payable to the Trustee under such Section).

          Section 6.10. Authenticating Agents. (a) The Trustee may appoint one
or more  Authenticating  Agents which shall be  authorized to act on behalf of
the Trustee in authenticating Certificates. Wherever reference is made in this
Agreement  to  the  authentication  of  Certificates  by  the  Trustee  or the
Trustee's  certificate of  authentication,  such reference  shall be deemed to
include authentication on behalf of the Trustee by an Authenticating Agent and
a  certificate  of  authentication  executed  on behalf of the  Trustee  by an
Authenticating   Agent.  Each  Authenticating  Agent  must  be  a  corporation
organized and doing business under the laws of the United States of America or
of any state,  having a combined capital and surplus of at least  $15,000,000,
authorized  under such laws to do a trust  business and subject to supervision
or examination by federal or state authorities.

          (b) Any Person into which any Authenticating  Agent may be merged or
converted or with which it may be  consolidated,  or any Person resulting from
any merger,  conversion or  consolidation  to which any  Authenticating  Agent
shall be a party, or any Person succeeding to the corporate agency business of
any  Authenticating  Agent,  shall  continue  to be the  Authenticating  Agent
without the execution or filing of any paper or any further act on the part of
the Trustee or the Authenticating Agent.

          (c) Any  Authenticating  Agent  may at any time  resign by giving at
least 30 days' advance  written  notice of  resignation to the Trustee and the
Depositor.   The  Trustee  may  at  any  time  terminate  the  agency  of  any
Authenticating   Agent  by  giving  written  notice  of  termination  to  such
Authenticating Agent and the Depositor. Upon receiving a notice of resignation
or upon such a termination,  or in case at any time any  Authenticating  Agent
shall cease to be eligible in accordance  with the  provisions of this Section
6.10,  the Trustee may appoint a successor  Authenticating  Agent,  shall give
written  notice of such  appointment to the Depositor and shall mail notice of
such appointment to all Holders of Certificates.  Any successor Authenticating
Agent upon  acceptance of its  appointment  hereunder shall become vested with
all  the  rights,  powers,  duties  and  responsibilities  of its  predecessor
hereunder, with like effect as if originally named as Authenticating Agent. No
successor  Authenticating  Agent shall be appointed  unless eligible under the
provisions  of  this  Section  6.10.  No   Authenticating   Agent  shall  have
responsibility  or  liability  for  any  action  taken  by it as  such  at the
direction  of the  Trustee.  Any  Authenticating  Agent  shall be  entitled to
reasonable compensation for its services and, if paid by the Trustee, it shall
be a  reimbursable  expense  pursuant to Section  6.12.  

          Section  6.11.  Indemnification  of  Trustee.  The  Trustee  and its
directors, officers, employees and agents shall be entitled to indemnification
from the Trust Fund for any loss,  liability or expense incurred in connection
with  any  legal  proceeding  and  incurred  without   negligence  or  willful
misconduct  on  their  part,  arising  out  of,  or in  connection  with,  the
acceptance or  administration of the trusts created  hereunder,  including the
costs and expenses of  defending  themselves  against any claim in  connection
with the exercise or performance  of any of their powers or duties  hereunder,
provided that:

                    (i) with respect to any such claim, the Trustee shall have
          given the  Depositor,  the Master  Servicer and the Holders  written
          notice  thereof  promptly  after the  Trustee  shall have  knowledge
          thereof;

                    (ii) while maintaining control over its own defense,
          the Trustee shall  cooperate and consult fully with the Depositor in
          preparing such defense;  and

                    (iii)  notwithstanding  anything  to the  contrary in this
          Section 6.11,  the Trust Fund shall not be liable for  settlement of
          any such claim by the Trustee entered into without the prior consent
          of the Depositor, which consent shall not be unreasonably withheld.

          The provisions of this Section 6.11 shall survive any termination of
this  Agreement  and the  resignation  or removal of the  Trustee and shall be
construed  to include,  but not be limited to any loss,  liability  or expense
under any environmental law.

          Section  6.12.  Fees and  Expenses  of  Trustee.  In addition to the
Trustee Fee, the Trustee  shall be entitled to receive,  and is  authorized to
pay to itself the amount of income or gain earned from the investment of funds
in the Certificate Account.

          Section 6.13.  Collection of Monies.  Except as otherwise  expressly
provided in this Agreement, the Trustee may demand payment or delivery of, and
shall  receive  and  collect,  all  money  and other  property  payable  to or
receivable by the Trustee  pursuant to this Agreement.  The Trustee shall hold
all such money and property received by it as part of the Trust Fund and shall
distribute  it as provided in this  Agreement.  If the Trustee  shall not have
timely received amounts to be remitted with respect to the Mortgage Loans from
the Master  Servicer,  the Trustee shall  request the Master  Servicer to make
such  distribution  as promptly as  practicable or legally  permitted.  If the
Trustee  shall  subsequently  receive any such amount,  it may  withdraw  such
request. 

          Section 6.14. Events of Default;  Trustee To Act;  Appointment
of Successor.  (a) The  occurrence of any one or more of the following  events
shall  constitute  an "Event  of  Default"):  

                    (i) Any  failure by the  Master  Servicer  to furnish  the
          Trustee the  Mortgage  Loan data  sufficient  to prepare the reports
          described in Section 4.03(a) which continues unremedied for a period
          of one Business Day after the date upon which written notice of such
          failure shall have been given to such Master Servicer by the Trustee
          or to such  Master  Servicer  and the  Trustee by the Holders of not
          less  than  25%  of  the  Class  Certificate  Principal  Amount  (or
          Aggregate  Notional  Amount) of each Class of Certificates  affected
          thereby; or

                    (ii) Any failure on the part of the Master  Servicer  duly
          to  observe  or perform  in any  material  respect  any other of the
          covenants  or  agreements  on  the  part  of  such  Master  Servicer
          contained in this Agreement which continues  unremedied for a period
          of 30 days (or 15 days,  in the case of a failure  to  maintain  any
          Insurance  Policy  required  to  be  maintained   pursuant  to  this
          Agreement)  after the date on which written  notice of such failure,
          requiring  the same to be  remedied,  shall  have been given to such
          Master  Servicer by the Trustee,  or to such Master Servicer and the
          Trustee by the Holders of not less than 25% of the Class Certificate
          Principal  Amount (or  Aggregate  Notional  Amount) of each Class of
          Certificates affected thereby; or 

                    (iii)  A  decree   or  order  of  a  court  or  agency  or
          supervisory  authority having  jurisdiction for the appointment of a
          conservator   or  receiver   or   liquidator   in  any   insolvency,
          readjustment  of debt,  marshalling  of assets  and  liabilities  or
          similar  proceedings,  or for the  winding-up or  liquidation of its
          affairs,  shall have been entered against the Master  Servicer,  and
          such decree or order shall have  remained in force  undischarged  or
          unstayed  for a period of 60 days or any  Rating  Agency  reduces or
          withdraws  or  threatens  to reduce or  withdraw  the  rating of the
          Certificates  because of the financial  condition or loan  servicing
          capability  of such  Master  Servicer;  or 

                    (iv) The Master  Servicer shall consent to the appointment
          of a  conservator  or  receiver  or  liquidator  in any  insolvency,
          readjustment  of  debt,   marshalling  of  assets  and  liabilities,
          voluntary  liquidation or similar proceedings of or relating to such
          Master Servicer or of or relating to all or substantially all of its
          property;  or 

                    (v)  The  Master  Servicer  shall  admit  in  writing  its
          inability  to pay its debts  generally  as they become  due,  file a
          petition  to  take  advantage  of  any   applicable   insolvency  or
          reorganization  statute,  make an assignment  for the benefit of its
          creditors or voluntarily suspend payment of its obligations; or 

                    (vi) The  Master  Servicer  shall be  dissolved,  or shall
          dispose of all or  substantially  all of its assets,  or consolidate
          with or merge into another  entity or shall permit another entity to
          consolidate  or merge into it, such that the  resulting  entity does
          not meet the  criteria  for a  successor  servicer as  specified  in
          Section 9.27 hereof;  or 

                    (vii) If a representation or warranty set forth in Section
          9.14 hereof  shall prove to be  incorrect as of the time made in any
          respect that  materially and adversely  affects the interests of the
          Certificateholders,  and the circumstance or condition in respect of
          which such  representation  or warranty was incorrect shall not have
          been  eliminated  or cured  within  60 days  after the date on which
          written  notice of such incorrect  representation  or warranty shall
          have been given to the Master  Servicer  by the  Trustee,  or to the
          Master  Servicer and the Trustee by the Holders of not less than 25%
          of the  Aggregate  Certificate  Principal  Amount  of each  Class of
          Certificates; or 

                    (viii) A sale or  pledge  of the any of the  rights of the
          Master Servicer  hereunder or an assignment of this Agreement by the
          Master  Servicer  or a  delegation  of the  rights  or duties of the
          Master  Servicer  hereunder  shall have  occurred  in any manner not
          otherwise  permitted hereunder and without the prior written consent
          of the Trustee and  Certificateholders  holding more than 50% of the
          Class Certificate Principal Amount (or Aggregate Notional Amount) of
          each Class of Certificates;  or 

                    (ix) Any  Servicer  at any time is not  either an FNMA- or
          FHLMC-  approved  Seller/Servicer,  and the Master  Servicer has not
          terminated  the rights and  obligations  of such Servicer  under the
          applicable  Servicing  Agreement  and replaced such Servicer with an
          FNMA- or  FHLMC-approved  servicer  within 30 days of the absence of
          such approval; or 

                    (x) Any  failure  of the Master  Servicer  to remit to the
          Trustee  any  payment  required  to be made to the  Trustee  for the
          benefit  of  Certificateholders  under the terms of this  Agreement,
          including any Advance, on any Deposit Date.

          If an Event of Default described in clauses (i) through (ix) of this
Section 6.14 shall occur,  then, in each and every case, subject to applicable
law, so long as any such Event of Default shall not have been remedied  within
any period of time prescribed by this Section 6.14, the Trustee,  by notice in
writing  to  the  Master   Servicer   may,  and  shall,   if  so  directed  by
Certificateholders evidencing more than 50% of the Class Certificate Principal
Amount (or Aggregate Notional Amount) of each Class of Certificates, terminate
all of the rights and obligations of the Master Servicer  hereunder and in and
to the  Mortgage  Loans  and the  proceeds  thereof.  If an Event  of  Default
described in clause (x) of this Section  6.14 shall occur,  then,  in each and
every case,  subject to applicable  law, the Trustee,  by notice in writing to
the  Master  Servicer,   shall  promptly  terminate  all  of  the  rights  and
obligations of the Master Servicer  hereunder and in and to the Mortgage Loans
and the proceeds  thereof.  On or after the receipt by the Master  Servicer of
such written notice, all authority and power of the Master Servicer,  and only
in its capacity as Master Servicer under this Agreement,  whether with respect
to the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee
pursuant to and under the terms of this  Agreement;  and the Trustee is hereby
authorized  and empowered to execute and deliver,  on behalf of the defaulting
Master Servicer as  attorney-in-fact  or otherwise,  any and all documents and
other instruments,  and to do or accomplish all other acts or things necessary
or appropriate to effect the purposes of such notice of  termination,  whether
to complete the transfer and  endorsement  or assignment of the Mortgage Loans
and related  documents or otherwise.  The defaulting Master Servicer agrees to
cooperate  with the Trustee in effecting  the  termination  of the  defaulting
Master  Servicer's  responsibilities  and rights  hereunder as Master Servicer
including,  without limitation,  notifying Mortgagors of the assignment of the
master  servicing  function  and  providing  the Trustee or its  designee  all
documents and records in electronic or other form  reasonably  requested by it
to enable  the  Trustee  or its  designee  to  assume  the  defaulting  Master
Servicer's   functions   hereunder   and  the  transfer  to  the  Trustee  for
administration  by it of all amounts which shall at the time be or should have
been deposited by the  defaulting  Master  Servicer in the Collection  Account
maintained by such  defaulting  Master  Servicer and any other account or fund
maintained  with  respect to the  Certificates  or  thereafter  received  with
respect to the Mortgage Loans. The Master Servicer being terminated shall bear
all costs of a master servicing  transfer,  including but not limited to those
of the Trustee reasonably allocable to specific employees and overhead,  legal
fees and expenses,  accounting and financial consulting fees and expenses, and
costs of amending the Agreement, if necessary.

          Notwithstanding   the   termination  of  its  activities  as  Master
Servicer,  each  terminated  Master  Servicer shall continue to be entitled to
reimbursement to the extent provided in Section 4.02(i),  (ii),  (iii),  (iv),
(v), (vi),  (vii), (ix) and (xi) to the extent such  reimbursement  relates to
the period prior to such Master Servicer's termination.

          If any Event of Default  shall  occur,  the Trustee  shall  promptly
notify the Rating  Agencies of the nature and extent of such Event of Default.
The Trustee shall  immediately give written notice to the Master Servicer upon
such Master Servicer's failure to remit funds on the Deposit Date.

          (b) On and after the time the Master  Servicer  receives a notice of
termination  from the  Trustee  pursuant  to Section  6.14(a)  or the  Trustee
receives the  resignation  of the Master  Servicer  evidenced by an Opinion of
Counsel pursuant to Section 9.29, the Trustee,  unless another master servicer
shall have been  appointed,  shall be the  successor  in all  respects  to the
Master  Servicer  in its  capacity  as  such  under  this  Agreement  and  the
transactions  set forth or  provided  for herein and shall have all the rights
and powers and be subject to all the responsibilities,  duties and liabilities
relating  thereto  and  arising  thereafter  placed  on  the  Master  Servicer
hereunder,  including the obligation to make Advances; provided, however, that
any failure to perform  such duties or  responsibilities  caused by the Master
Servicer's failure to provide information required by this Agreement shall not
be  considered a default by the Trustee  hereunder.  In addition,  the Trustee
shall have no  responsibility  for any act or omission of the Master  Servicer
prior to the issuance of any notice of termination and shall have no liability
relating to the  representations  and  warranties  of the Master  Servicer set
forth in Section  9.14.  In the  Trustee's  capacity  as such  successor,  the
Trustee shall have the same  limitations  on liability  herein  granted to the
Master Servicer.  As compensation  therefor,  the Trustee shall be entitled to
receive all compensation  payable to the Master Servicer under this Agreement,
including the Master Servicing Fee.

          (c)  Notwithstanding  the above,  the  Trustee  may,  if it shall be
unwilling to continue to so act, or shall, if it is unable to so act, appoint,
or petition a court of  competent  jurisdiction  to appoint,  any  established
housing and home finance institution servicer,  master servicer,  servicing or
mortgage servicing institution having a net worth of not less than $15,000,000
and meeting such other  standards for a successor  master  servicer as are set
forth in this  Agreement,  as the  successor  to such  Master  Servicer in the
assumption of all of the  responsibilities,  duties or liabilities of a master
servicer,  like the Master Servicer. Any entity designated by the Trustee as a
successor  master  servicer  may be an  Affiliate  of the  Trustee;  provided,
however,  that,  unless such Affiliate  meets the net worth  requirements  and
other standards set forth herein for a successor master servicer, the Trustee,
in its individual capacity shall agree, at the time of such designation, to be
and remain liable to the Trust Fund for such Affiliate's actions and omissions
in performing its duties  hereunder.  In connection with such  appointment and
assumption,  the Trustee may make such  arrangements  for the  compensation of
such  successor  out of payments on  Mortgage  Loans as it and such  successor
shall agree;  provided,  however, that no such compensation shall be in excess
of that  permitted  to the Master  Servicer  hereunder.  The  Trustee and such
successor shall take such actions, consistent with this Agreement, as shall be
necessary to effectuate any such  succession  and may make other  arrangements
with  respect  to the  servicing  to be  conducted  hereunder  which  are  not
inconsistent  herewith.  The Master  Servicer shall cooperate with the Trustee
and any successor  master  servicer in effecting the termination of the Master
Servicer's   responsibilities   and  rights   hereunder   including,   without
limitation,  notifying  Mortgagors of the  assignment of the master  servicing
functions  and  providing  the  Trustee  and  successor  master  servicer,  as
applicable,  all documents and records in electronic or other form  reasonably
requested  by it to  enable  it to  assume  the  Master  Servicer's  functions
hereunder and the transfer to the Trustee or such successor  master  servicer,
as  applicable,  all  amounts  which  shall at the time be or should have been
deposited  by the Master  Servicer  in the  Collection  Account  and any other
account or fund maintained  with respect to the  Certificates or thereafter be
received with respect to the Mortgage Loans. Neither the Trustee nor any other
successor master servicer shall be deemed to be in default hereunder by reason
of any failure to make, or any delay in making, any distribution  hereunder or
any  portion  thereof  caused by (i) the  failure  of the Master  Servicer  to
deliver,  or any delay in delivering,  cash,  documents or records to it, (ii)
the failure of the Master Servicer to cooperate as required by this Agreement,
(iii) the failure of the Master  Servicer to deliver the Mortgage Loan data to
the Trustee as required by this Agreement or (iv) restrictions  imposed by any
regulatory  authority having  jurisdiction  over the Master Servicer.  

          Section 6.15.  Additional Remedies of Trustee Upon Event of Default.
During  the  continuance  of any Event of  Default,  so long as such  Event of
Default shall not have been remedied,  the Trustee,  in addition to the rights
specified  in  Section  6.14,  shall  have the  right,  in its own name and as
trustee of an express trust, to take all actions now or hereafter  existing at
law, in equity or by statute to enforce its rights and remedies and to protect
the interests,  and enforce the rights and remedies, of the Certificateholders
(including the institution and prosecution of all judicial, administrative and
other  proceedings  and the filings of proofs of claim and debt in  connection
therewith).  Except as  otherwise  expressly  provided in this  Agreement,  no
remedy  provided for by this Agreement shall be exclusive of any other remedy,
and each and every  remedy  shall be  cumulative  and in addition to any other
remedy,  and no delay or omission to exercise any right or remedy shall impair
any such  right or  remedy  or shall be  deemed to be a waiver of any Event of
Default.

          Section  6.16.  Waiver  of  Defaults.  35% or more of the  Aggregate
Voting  Interests  of  Certificateholders  may waive any  default  or Event of
Default  by  the  Master  Servicer  in  the  performance  of  its  obligations
hereunder,  except that a default in the making of any required deposit to the
Certificate  Account that would result in a failure of the Trustee to make any
required  payment of principal of or interest on the  Certificates may only be
waived with the consent of 100% of the affected  Certificateholders.  Upon any
such waiver of a past  default,  such  default  shall cease to exist,  and any
Event of Default  arising  therefrom shall be deemed to have been remedied for
every purpose of this Agreement. No such waiver shall extend to any subsequent
or other default or impair any right  consequent  thereon except to the extent
expressly  so waived.  

          Section  6.17.  Notification  to Holders.  Upon  termination  of the
Master Servicer or appointment of a successor to the Master Servicer,  in each
case as provided  herein,  the Trustee shall  promptly mail notice  thereof by
first  class  mail to the  Certificateholders  at their  respective  addresses
appearing on the Certificate Register.  The Trustee shall also, within 45 days
after  the  occurrence  of any Event of  Default  known to the  Trustee,  give
written  notice  thereof to  Certificateholders,  unless such Event of Default
shall  have been  cured or waived  prior to the  issuance  of such  notice and
within   such   45-day   period.    

          Section 6.18. Directions by Certificateholders and Duties of Trustee
During  Event of Default.  Subject to the  provisions  of Section 8.01 hereof,
during  the  continuance  of any Event of  Default,  Holders  of  Certificates
evidencing  not less than 25% of the Class  Certificate  Principal  Amount (or
Aggregate  Notional Amount) of each Class of Certificates may direct the time,
method and place of conducting any proceeding for any remedy  available to the
Trustee,  or exercising any trust or power  conferred upon the Trustee,  under
this  Agreement;  provided,  however,  that  the  Trustee  shall  be  under no
obligation  to pursue any such  remedy,  or to  exercise  any of the trusts or
powers vested in it by this Agreement (including,  without limitation, (i) the
conducting or defending of any administrative  action or litigation  hereunder
or in relation  hereto and (ii) the  terminating of the Master Servicer or any
successor  master  servicer  from its  rights  and  duties as master  servicer
hereunder)   at   the   request,   order   or   direction   of   any   of  the
Certificateholders,  unless such Certificateholders  shall have offered to the
Trustee  reasonable  security  or  indemnity  against the cost,  expenses  and
liabilities  which may be incurred therein or thereby;  and, provided further,
that,  subject to the  provisions of Section 8.01,  the Trustee shall have the
right to decline to follow any such  direction if the Trustee,  in  accordance
with an Opinion  of  Counsel,  determines  that the  action or  proceeding  so
directed may not lawfully be taken or if the Trustee in good faith  determines
that the  action or  proceeding  so  directed  would  involve  it in  personal
liability or be unjustly prejudicial to the non-assenting  Certificateholders.

          Section 6.19.  Action Upon Certain  Failures of the Master  Servicer
and Upon Event of  Default.  In the event that the  Trustee  shall have actual
knowledge of any action or inaction of the Master  Servicer  that would become
an Event of  Default  upon the  Master  Servicer's  failure to remedy the same
after notice, the Trustee shall give notice thereof to the Master Servicer.

          Section 6.20. Limitation of Liability. The Certificates are executed
by the Trustee,  not in its  individual  capacity but solely as Trustee of the
Trust, in the exercise of the powers and authority  conferred and vested in it
by this Agreement. Each of the undertakings and agreements made on the part of
the  Trustee  in the  Certificates  is made  and  intended  not as a  personal
undertaking  or  agreement  by the  Trustee but is made and  intended  for the
purpose of binding only the Trust.

          Section  6.21.  Trustee May Enforce  Claims  Without  Possession  of
Certificates.  All  rights of action and claims  under this  Agreement  or the
Certificates  may be  prosecuted  and  enforced  by the  Trustee  without  the
possession  of any of  the  Certificates  or  the  production  thereof  in any
proceeding  relating  thereto,  and such  preceding  instituted by the Trustee
shall be brought in its own name or in its  capacity as Trustee.  Any recovery
of  judgment  shall,  after  provision  for  the  payment  of  the  reasonable
compensation,  expenses,  disbursement and advances of the Trustee, its agents
and counsel, be for the ratable benefit or the  Certificateholders  in respect
of which such  judgment  has been  recovered.  

          Section 6.22. Suits for Enforcement.  In case an Event of Default or
other default by the Master  Servicer or the Depositor  hereunder  shall occur
and be continuing,  the Trustee, in its discretion, may proceed to protect and
enforce  its rights and the rights of the Holders of  Certificates  under this
Agreement by a suit,  action or  proceeding  in equity or at law or otherwise,
whether for the specific performance of any covenant or agreement contained in
this  Agreement  or in aid of the  execution  of any  power  granted  in  this
Agreement  or for the  enforcement  of any  other  legal,  equitable  or other
remedy, as the Trustee, being advised by counsel, shall deem most effectual to
protect   and   enforce   any  of  the   rights   of  the   Trustee   and  the
Certificateholders.

          Section  6.23.  Waiver of Bond  Requirement.  The  Trustee  shall be
relieved of, and each Certificateholder  hereby waives, any requirement of any
jurisdiction in which the Trust, or any part thereof,  may be located that the
Trustee post a bond or other surety with any court, agency or body whatsoever.

          Section  6.24.  Waiver  of  Inventory,   Accounting  and  Appraisal
Requirement.  The  Trustee  shall be relieved  of, and each  Certificateholder
hereby waives,  any requirement of any jurisdiction in which the Trust, or any
part thereof,  may be located that the Trustee file any inventory,  accounting
or appraisal of the Trust with any court, agency or body at any time or in any
manner whatsoever.

                                 ARTICLE VII

                           PURCHASE AND TERMINATION

                               OF THE TRUST FUND

          Section  7.01.   Termination  of  Trust  Fund  Upon   Repurchase  or
Liquidation  of  All  Mortgage  Loans.  (a)  The  respective  obligations  and
responsibilities  of the Trustee and the Master Servicer created hereby (other
than the obligation of the Trustee to make payments to  Certificateholders  as
set forth in Section 7.02,  the  obligation  of the Master  Servicer to make a
final  remittance  to the  Trustee for deposit  into the  Certificate  Account
pursuant to Section  4.01 and the  obligations  of the Master  Servicer to the
Trustee pursuant to Sections 9.10 and 9.14), shall terminate on the earlier of
(i) the final payment or other liquidation of the last Mortgage Loan remaining
in the Trust Fund and the disposition of all REO Property and (ii) the sale of
the property held by the Trust Fund in accordance with Section 7.01(b) or (c);
provided,  however,  that in no event  shall the  Trust  Fund  created  hereby
continue  beyond the earlier of (i) the  expiration of 21 years from the death
of the last  survivor  of the  descendants  of  Joseph  P.  Kennedy,  the late
Ambassador  of the United  States to the Court of St.  James's,  living on the
date hereof,  and (ii) the Latest  Possible  Maturity Date. Any termination of
the Trust Fund shall be carried  out in such a manner so that the  termination
of each REMIC  included  therein  shall  qualify as a "qualified  liquidation"
under the REMIC Provisions.

          (b) On any  Distribution  Date occurring after the date on which the
aggregate  Scheduled  Principal Balance of the Mortgage Loans is less than 10%
of the Cut-off Date Aggregate  Principal Balance,  the Depositor may cause the
Trust  Fund to  adopt a plan  of  complete  liquidation  pursuant  to  Section
7.03(a)(i) hereof to sell all of its property.  The property of the Trust Fund
shall be sold at a price (the  "Termination  Price") equal to: (i) 100% of the
unpaid  principal  balance of each  Mortgage  Loan on the day of such purchase
plus interest accrued thereon at the applicable  Mortgage Rate with respect to
any Mortgage Loan to the Due Date in the Due Period immediately  preceding the
related  Distribution  Date to the date of such  repurchase  and (ii) the fair
market  value of any REO Property  and any other  property  held by any REMIC,
such fair market value to be determined by an appraiser or appraisers mutually
agreed upon by the Master Servicer and the Trustee.

          Section 7.02.  Procedure Upon  Termination of Trust Fund. (a) Notice
of any termination pursuant to the provisions of Section 7.01,  specifying the
Distribution  Date upon which the final  distribution  shall be made, shall be
given promptly by the Trustee by first class mail to Certificateholders mailed
(x) no later than five  Business  Days after the Trustee has  received  notice
from  the  Depositor  of its  intent  to  exercise  its  right  to  cause  the
termination  of the Trust Fund  pursuant  to  Section  7.01(b) or (y) upon the
final payment or other  liquidation  of the last Mortgage Loan or REO Property
in the Trust Fund.  Such notice shall specify (A) the  Distribution  Date upon
which final  distribution on the  Certificates  of all amounts  required to be
distributed to  Certificateholders  pursuant to Section 5.02 will be made upon
presentation  and surrender of the Certificates at the Corporate Trust Office,
and (B) that the Record Date otherwise applicable to such Distribution Date is
not applicable,  distribution  being made only upon presentation and surrender
of the Certificates at the office or agency of the Trustee therein  specified.
The Trustee shall give such notice to the Master  Servicer and the Certificate
Registrar  at the time such  notice is given to Holders  of the  Certificates.
Upon any such  termination,  the  duties  of the  Certificate  Registrar  with
respect to the  Certificates  shall terminate and the Trustee shall terminate,
or  request  the Master  Servicer  to  terminate,  the  Collection  Account it
maintains,  the  Certificate  Account and any other account or fund maintained
with  respect  to  the  Certificates,  subject  to  the  Trustee's  obligation
hereunder to hold all amounts payable to  Certificateholders  in trust without
interest pending such payment.

          (b) In the event  that all of the  Holders  do not  surrender  their
Certificates for cancellation  within three months after the time specified in
the  above-mentioned  written notice,  the Trustee shall give a second written
notice to the remaining Certificateholders to surrender their Certificates for
cancellation  and receive the final  distribution  with  respect  thereto.  If
within one year after the second notice any  Certificates  shall not have been
surrendered  for  cancellation,  the  Trustee  may take  appropriate  steps to
contact  the  remaining   Certificateholders   concerning  surrender  of  such
Certificates,  and  the  cost  thereof  shall  be  paid  out  of  the  amounts
distributable to such Holders. If within two years after the second notice any
Certificates  shall not have been  surrendered for  cancellation,  the Trustee
shall,  subject to  applicable  state law  relating to  escheatment,  hold all
amounts  distributable  to such  Holders for the benefit of such  Holders.  No
interest shall accrue on any amount held by the Trustee and not distributed to
a Certificateholder due to such  Certificateholder's  failure to surrender its
Certificate(s)  for payment of the final  distribution  thereon in  accordance
with this Section.

          Section 7.03.  Additional Trust Fund Termination  Requirements.  (a)
The Trust Fund shall be terminated in accordance with the following additional
requirements,  unless  the  Trustee  seeks  (at  the  request  of  the  Master
Servicer), and subsequently receives, an Opinion of Counsel (at the expense of
the Master Servicer),  addressed to the Trustee to the effect that the failure
of the Trust Fund to comply with the  requirements  of this  Section 7.03 will
not (i)  result  in the  imposition  of taxes on any  REMIC  under  the  REMIC
Provisions or (ii) cause any REMIC established hereunder to fail to qualify as
a REMIC at any time that any Certificates are outstanding:

                    (i)  Within 89 days prior to the time of the making of the
          final payment on the Certificates, the Trustee (upon (x) the sale of
          the  property of the Trust Fund by the  Trustee  pursuant to Section
          7.01(b)  or (y)  notification  by the  Depositor  that it intends to
          exercise  its  option to cause the  termination  of the Trust  Fund)
          shall  adopt a plan of  complete  liquidation  of the Trust  Fund on
          behalf  of each  REMIC,  meeting  the  requirements  of a  qualified
          liquidation under the REMIC Provisions;

                    (ii) The sale of the assets of the Trust Fund  pursuant to
          Section  7.02  shall be a sale for cash and shall  occur at or after
          the time of  adoption  of such a plan of  complete  liquidation  and
          prior  to  the  time  of  making  of  the  final   payment   on  the
          Certificates;

                    (iii) On the  date  specified  for  final  payment  of the
          Certificates,  the Trustee shall,  after payment of any unreimbursed
          Advances,   Servicing   Advances,   Servicing   Fees  or  other  fee
          compensation of the Special Servicer payable pursuant to the Special
          Servicing  Compensation  Agreement,   make  final  distributions  of
          principal  and  interest  on the  Certificates  in  accordance  with
          Section 5.02 and distribute or credit, or cause to be distributed or
          credited,  to the Holders of the Residual  Certificates  all cash on
          hand after such final  payment  (other  than cash  retained  to meet
          claims), and the Trust Fund (and each REMIC) shall terminate at that
          time; and 

                    (iv) In no event may the final payment on the Certificates
          or the final  distribution  or credit to the Holders of the Residual
          Certificates  be made  after the 89th day from the date on which the
          plan of complete  liquidation is adopted. (b) By its acceptance of a
          Residual Certificate,  each Holder thereof hereby (i) authorizes the
          Trustee to take such action as may be  necessary  to adopt a plan of
          complete  liquidation  of the related  REMIC and (ii) agrees to take
          such other  action as may be  necessary  to adopt a plan of complete
          liquidation  of the  related  REMIC,  which  authorization  shall be
          binding upon all successor Residual Certificateholders.

                                 ARTICLE VIII

                         RIGHTS OF CERTIFICATEHOLDERS

          Section  8.01.  Limitation  on Rights of  Holders.  (a) The death or
incapacity  of any  Certificateholder  shall not  operate  to  terminate  this
Agreement  or this Trust Fund,  nor  entitle  such  Certificateholder's  legal
representatives  or  heirs  to  claim an  accounting  or take  any  action  or
proceeding in any court for a partition or winding up of this Trust Fund,  nor
otherwise affect the rights, obligations and liabilities of the parties hereto
or  any  of  them.   Except  as  otherwise   expressly   provided  herein,  no
Certificateholder,  solely  by virtue  of its  status as a  Certificateholder,
shall have any right to vote or in any  manner  otherwise  control  the Master
Servicer or the operation and management of the Trust Fund, or the obligations
of the parties  hereto,  nor shall anything  herein set forth, or contained in
the  terms  of  the  Certificates,  be  construed  so  as  to  constitute  the
Certificateholders from time to time as partners or members of an association,
nor shall any  Certificateholder be under any liability to any third person by
reason of any action  taken by the parties to this  Agreement  pursuant to any
provision hereof.

          (b)  No  Certificateholder,  solely  by  virtue  of  its  status  as
Certificateholder,  shall  have any  right by  virtue  or by  availing  of any
provision of this  Agreement to institute  any suit,  action or  proceeding in
equity or at law upon or under or with respect to this Agreement,  unless such
Holder previously shall have given to the Trustee a written notice of an Event
of Default and of the  continuance  thereof,  as  hereinbefore  provided,  and
unless also the Holders of  Certificates  evidencing  not less than 25% of the
Class  Certificate   Principal  Amount  (or  Aggregate   Notional  Amount)  of
Certificates of each Class shall have made written request upon the Trustee to
institute such action, suit or proceeding in its own name as Trustee hereunder
and shall have  offered to the Trustee  such  reasonable  indemnity  as it may
require against the cost,  expenses and liabilities to be incurred  therein or
thereby,  and the  Trustee,  for sixty days after its receipt of such  notice,
request and offer of indemnity,  shall have  neglected or refused to institute
any such action,  suit or proceeding and no direction  inconsistent  with such
written  request has been given such Trustee during such  sixty-day  period by
such Certificateholders; it being understood and intended, and being expressly
covenanted by each  Certificateholder  with every other  Certificateholder and
the Trustee,  that no one or more Holders of Certificates shall have any right
in any manner  whatever  by virtue or by  availing  of any  provision  of this
Agreement  to affect,  disturb or  prejudice  the rights of the Holders of any
other of such  Certificates,  or to obtain or seek to obtain  priority over or
preference  to any other  such  Holder,  or to  enforce  any right  under this
Agreement,  except in the manner  herein  provided  and for the benefit of all
Certificateholders.  For the protection  and  enforcement of the provisions of
this  Section,  each and  every  Certificateholder  and the  Trustee  shall be
entitled to such relief as can be given either at law or in equity.

          Section 8.02.  Access to List of Holders.  (a) If the Trustee is not
acting as Certificate  Registrar,  the  Certificate  Registrar will furnish or
cause to be furnished to the Trustee, within fifteen days after receipt by the
Certificate  Registrar of a request by the Trustee in writing, a list, in such
form as the Trustee may reasonably  require, of the names and addresses of the
Certificateholders of each Class as of the most recent Record Date.

          (b) If three or more  Holders  or  Certificate  Owners  (hereinafter
referred  to as  "Applicants")  apply  in  writing  to the  Trustee,  and such
application  states  that the  Applicants  desire to  communicate  with  other
Holders  with  respect  to their  rights  under  this  Agreement  or under the
Certificates  and is  accompanied  by a copy of the  communication  which such
Applicants propose to transmit,  then the Trustee shall,  within five Business
Days after the receipt of such application,  afford such Applicants reasonable
access during the normal business hours of the Trustee to the most recent list
of Certificateholders  held by the Trustee or shall, as an alternative,  send,
at  the  Applicants'  expense,  the  written  communication  proffered  by the
Applicants to all  Certificateholders at their addresses as they appear in the
Certificate Register.

          (c) Every Holder or Certificate  Owner,  if the Holder is a Clearing
Agency, by receiving and holding a Certificate, agrees with the Depositor, the
Master  Servicer,  the Certificate  Registrar and the Trustee that neither the
Depositor,  the Master  Servicer,  the  Certificate  Registrar nor the Trustee
shall be held  accountable by reason of the disclosure of any such information
as to the names and addresses of the Certificateholders hereunder,  regardless
of the source from which such  information  was derived.  

          Section  8.03.  Acts of Holders of  Certificates.  (a) Any  request,
demand,  authorization,  direction,  notice,  consent,  waiver or other action
provided  by this  Agreement  to be given or taken by Holders  or  Certificate
Owner, if the Holder is a Clearing Agency, may be embodied in and evidenced by
one or more instruments of substantially  similar tenor signed by such Holders
in  person  or by agent  duly  appointed  in  writing;  and,  except as herein
otherwise  expressly  provided,  such action shall become  effective when such
instrument or instruments  are delivered to the Trustee and,  where  expressly
required herein,  to the Master  Servicer.  Such instrument or instruments (as
the action  embodies  therein  and  evidenced  thereby)  are herein  sometimes
referred to as an "Act" of the Holders signing such instrument or instruments.
Proof of execution of any such instrument or of a writing  appointing any such
agents shall be sufficient for any purpose of this Agreement and conclusive in
favor of the Trustee and Master  Servicer,  if made in the manner  provided in
this Section.  Each of the Trustee and Master  Servicer shall promptly  notify
the other of receipt of any such instrument by it, and shall promptly  forward
a copy of such instrument to the other.

          (b) The fact and date of the  execution  by any  Person  of any such
instrument  or  writing  may be proved by the  affidavit  of a witness of such
execution  or by the  certificate  of  any  notary  public  or  other  officer
authorized  by law to take  acknowledgments  or  deeds,  certifying  that  the
individual  signing  such  instrument  or  writing  acknowledged  to  him  the
execution  thereof.  Whenever such execution is by an officer of a corporation
or a member of a partnership  on behalf of such  corporation  or  partnership,
such  certificate or affidavit shall also constitute  sufficient  proof of his
authority.  The fact  and date of the  execution  of any  such  instrument  or
writing,  or the authority of the  individual  executing the same, may also be
proved in any other manner which the Trustee deems sufficient.

          (c) The ownership of Certificates  (whether or not such Certificates
shall be overdue  and  notwithstanding  any  notation  of  ownership  or other
writing  thereon made by anyone other than the Trustee) shall be proved by the
Certificate  Register,  and neither the Trustee, the Master Servicer,  nor the
Depositor  shall be affected by any notice to the  contrary.  (d) Any request,
demand,  authorization,  direction, notice, consent, waiver or other action by
the  Holder of any  Certificate  shall bind  every  future  Holder of the same
Certificate and the Holder of every  Certificate  issued upon the registration
of transfer thereof or in exchange therefor or in lieu thereof,  in respect of
anything  done,  omitted or  suffered  to be done by the Trustee or the Master
Servicer in reliance  thereon,  whether or not notation of such action is made
upon such Certificate.

                                  ARTICLE IX

                ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

                            BY THE MASTER SERVICER

          Section 9.01. Duties of the Master Servicer. The Certificateholders,
by their purchase and  acceptance of the  Certificates,  appoint  Norwest Bank
Minnesota,  National Association, as Master Servicer. For and on behalf of the
Depositor,  the Trustee and the Certificateholders,  the Master Servicer shall
master  service the Mortgage  Loans in accordance  with the provisions of this
Agreement and the provisions of the applicable Servicing Agreement.

          Section 9.02.  Master  Servicer  Fidelity  Bond and Master  Servicer
Errors  and  Omissions  Insurance  Policy.  (a) The  Master  Servicer,  at its
expense, shall maintain in effect a Master Servicer Fidelity Bond and a Master
Servicer  Errors and  Omissions  Insurance  Policy,  affording  coverage  with
respect to all directors, officers, employees and other Persons acting on such
Master Servicer's behalf, and covering errors and omissions in the performance
of the Master Servicer's obligations hereunder. The Master Servicer Errors and
Omissions  Insurance Policy and the Master Servicer  Fidelity Bond shall be in
such form and amount that would meet the  requirements  of FNMA or FHLMC if it
were the  purchaser  of the  Mortgage  Loans.  The Master  Servicer  shall (i)
require each Servicer to maintain an Errors and Omissions Insurance Policy and
a Servicer  Fidelity Bond in accordance  with the provisions of the applicable
Servicing  Agreement,  (ii)  cause  each  Servicer  to  provide  to the Master
Servicer certificates evidencing that such policy and bond is in effect and to
furnish to the Master  Servicer  any notice of  cancellation,  non-renewal  or
modification  of the  policy  or bond  received  by it,  as and to the  extent
provided in the applicable  Servicing  Agreement,  and (iii) furnish copies of
the  certificates  and notices  referred to in clause (ii) to the Trustee upon
its request.  (b) The Master Servicer shall promptly report to the Trustee any
material  changes that may occur in the Master  Servicer  Fidelity Bond or the
Master Servicer Errors and Omissions Insurance Policy and shall furnish to the
Trustee,  on request,  certificates  evidencing  that such bond and  insurance
policy are in full force and effect. The Master Servicer shall promptly report
to the  Trustee all cases of  embezzlement  or fraud,  if such events  involve
funds relating to the Mortgage Loans. The total losses,  regardless of whether
claims are filed with the applicable insurer or surety,  shall be disclosed in
such reports together with the amount of such losses covered by insurance.  If
a bond or insurance  claim report is filed with any of such bonding  companies
or insurers,  the Master Servicer shall promptly furnish a copy of such report
to the Trustee.  Any amounts  relating to the Mortgage Loans  collected by the
Master  Servicer  under any such bond or policy shall be promptly  remitted by
the Master Servicer to the Trustee for deposit into the  Certificate  Account.
Any amounts relating to the Mortgage Loans collected by any Servicer under any
such bond or policy  shall be  remitted  to the Master  Servicer to the extent
provided in the applicable Servicing Agreement.

          Section 9.03.  Master  Servicer's  Financial  Statements and Related
Information.  For each year this Agreement is in effect,  the Master  Servicer
shall submit to the Trustee,  each Rating  Agency and the  Depositor a copy of
its annual unaudited financial  statements on or prior to May 31 of each year.
Such financial  statements  shall include a balance sheet,  income  statement,
statement of retained  earnings,  statement  of  additional  paid-in  capital,
statement of changes in financial position and all related notes and schedules
and shall be in comparative form, certified by a nationally recognized firm of
Independent  Accountants to the effect that such  statements were examined and
prepared in accordance with generally accepted  accounting  principles applied
on a basis consistent with that of the preceding year.

          Section  9.04.  Power to Act;  Procedures.  (a) The Master  Servicer
shall  master  service  the  Mortgage  Loans  and shall  have  full  power and
authority,  subject to the REMIC  Provisions  and the  provisions of Article X
hereof,  and each Servicer  shall have full power and authority (to the extent
provided in the applicable  Servicing Agreement) to do any and all things that
it may deem  necessary or  desirable  in  connection  with the  servicing  and
administration  of the Mortgage Loans,  including but not limited to the power
and authority (i) to execute and deliver, on behalf of the  Certificateholders
and the  Trustee,  customary  consents  or waivers and other  instruments  and
documents,  (ii)  to  consent  to  transfers  of any  Mortgaged  Property  and
assumptions of the Mortgage Notes and related Mortgages,  (iii) to collect any
Insurance   Proceeds  and  Liquidation   Proceeds,   and  (iv)  to  effectuate
foreclosure  or other  conversion of the  ownership of the Mortgaged  Property
securing any Mortgage Loan, in each case, in accordance with the provisions of
this Agreement and the related Servicing  Agreement,  as applicable;  provided
that the Master  Servicer shall not take, or knowingly  permit any Servicer to
take, any action that is inconsistent  with or prejudices the interests of the
Trust Fund or the  Certificateholders  in any Mortgage  Loan or the rights and
interests of the Depositor,  the Trustee and the Certificateholders under this
Agreement.  The Master  Servicer shall  represent and protect the interests of
the Trust Fund in the same manner as it protects its own interests in mortgage
loans in its own portfolio in any claim,  proceeding or litigation regarding a
Mortgage  Loan  and  shall  not  make or  permit  any  Servicer  to  make  any
modification,  waiver or amendment of any term of any Mortgage Loan that would
cause the Trust Fund 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.  Without
limiting the generality of the foregoing,  the Master Servicer in its own name
or in the name of a Servicer,  and each Servicer, to the extent such authority
is  delegated to such  Servicer by the Master  Servicer  under the  applicable
Servicing  Agreement,  is hereby  authorized and empowered by the Trustee when
the Master Servicer or a Servicer, as the case may be, believes it appropriate
in its best judgment and in accordance with Accepted  Servicing  Practices and
the  applicable  Servicing  Agreement,  to execute and  deliver,  on behalf of
itself and the  Certificateholders,  the  Trustee or any of them,  any and all
instruments of satisfaction or cancellation,  or of partial or full release or
discharge and all other comparable  instruments,  with respect to the Mortgage
Loans and with respect to the Mortgaged Properties.  The Trustee shall furnish
the Master Servicer,  upon request, with any powers of attorney empowering the
Master  Servicer  or any  Servicer  to  execute  and  deliver  instruments  of
satisfaction or cancellation,  or of partial or full release or discharge, and
to foreclose upon or otherwise liquidate  Mortgaged  Property,  and to appeal,
prosecute or defend in any court action  relating to the Mortgage Loans or the
Mortgaged Property,  in accordance with the applicable Servicing Agreement and
this  Agreement,  and  the  Trustee  shall  execute  and  deliver  such  other
documents,  as the Master  Servicer may request,  necessary or  appropriate to
enable the Master Servicer to master service and administer the Mortgage Loans
and carry out its duties  hereunder,  in each case in accordance with Accepted
Servicing Practices (and the Trustee shall have no liability for misuse of any
such powers of attorney by the Master Servicer or any Servicer). If the Master
Servicer or the Trustee  has been  advised  that it is likely that the laws of
the state in which action is to be taken  prohibit such action if taken in the
name of the Trustee or that the Trustee would be adversely  affected under the
"doing  business"  or tax laws of such  state if such  action  is taken in its
name,  then upon request of the Trustee,  the Master  Servicer shall join with
the  Trustee in the  appointment  of a  co-trustee  pursuant  to Section  6.09
hereof. In the performance of its duties hereunder,  the Master Servicer shall
be an independent contractor and shall not, except in those instances where it
is taking action in the name of the Trustee,  be deemed to be the agent of the
Trustee.  (b) In master  servicing and  administering  the Mortgage Loans, the
Master  Servicer  shall employ  procedures,  and shall cause each  Servicer to
employ  procedures  (including,  but not limited to,  collection  procedures),
consistent  with  the  applicable  Servicing  Agreement.  Consistent  with the
foregoing,  the Master  Servicer  may,  and may permit any Servicer to, in its
discretion  (i) waive any late  payment  charge  or any  prepayment  charge or
penalty interest in connection with the prepayment of a Mortgage Loan and (ii)
extend  the due dates for  payments  due on a  Mortgage  Note for a period not
greater than 120 days;  provided,  however,  that the maturity of any Mortgage
Loan shall not be extended  past the date on which the final payment is due on
the latest maturing  Mortgage Loan as of the Cut-off Date. In the event of any
extension  described in clause (ii) above,  the Master  Servicer shall make or
cause to be made Advances on the related  Mortgage Loan in accordance with the
provisions of Section 5.04 on the basis of the  amortization  schedule of such
Mortgage  Loan  without  modification  thereof  by reason  of such  extension.
Notwithstanding  anything  to the  contrary  in  this  Agreement,  the  Master
Servicer  shall  not,  unless  default  by the  related  Mortgagor  is, in the
reasonable judgment of the Master Servicer, imminent, permit any modification,
waiver or amendment of any material term of any Mortgage Loan  (including  but
not limited to the interest  rate,  the principal  balance,  the  amortization
schedule,  or any other term affecting the amount or timing of payments on the
Mortgage Loan or the  collateral  therefor)  unless the Master  Servicer shall
have provided or caused to be provided to the Trustee an Opinion of Counsel in
writing to the effect that such modification, waiver or amendment would not be
treated  as  giving  rise to a new debt  instrument  for  federal  income  tax
purposes and would not adversely affect the status of the REMIC.

          Section 9.05.  Servicing  Agreements Between the Master Servicer and
Servicers; Enforcement of Servicers' Obligations. (a) Each Servicing Agreement
requires the  applicable  Servicer to service the Mortgage Loans in accordance
with the provisions thereof.  References in this Agreement to actions taken or
to be taken by the Master  Servicer  include actions taken or to be taken by a
Servicer on behalf of the Master Servicer.  Any fees and other amounts payable
to such  Servicers  shall be  deducted  from  amounts  remitted  to the Master
Servicer by the  applicable  Servicer  and shall not be an  obligation  of the
Trust.

          (b) The Master  Servicer,  for the  benefit of the  Trustee  and the
Certificateholders,  shall enforce the  obligations of each Servicer under the
related Servicing Agreement,  and shall, in the event that a Servicer fails to
perform its  obligations in accordance with the related  Servicing  Agreement,
terminate the rights and  obligations  of such Servicer  thereunder and either
act as  servicer  of the  related  Mortgage  Loans or enter  into a  Servicing
Agreement with a successor  Servicer.  Such  enforcement,  including,  without
limitation,   the  legal  prosecution  of  claims,  termination  of  Servicing
Agreements  and the pursuit of other  appropriate  remedies,  shall be in such
form  and  carried  out to  such an  extent  and at  such  time as the  Master
Servicer, in its good faith business judgment, would require were it the owner
of the related Mortgage Loans. The Master Servicer shall pay the costs of such
enforcement  at its own expense,  and shall be reimbursed  therefor  initially
only (i) from a general  recovery  resulting from such enforcement only to the
extent,  if any, that such recovery  exceeds all amounts due in respect of the
related Mortgage Loans or (ii) from a specific recovery of costs,  expenses or
attorneys'  fees against the party against whom such  enforcement is directed,
and then,  to the extent that such amounts are  insufficient  to reimburse the
Master Servicer for the costs of such  enforcement,  (iii) from the Collection
Account.

          Section 9.06.  Collection of Taxes,  Assessments  and Similar Items.
(a) To the extent provided in the applicable Servicing  Agreement,  the Master
Servicer  shall cause each  Servicer to  establish  and  maintain  one or more
custodial  accounts at a  depository  institution  (which may be a  depository
institution  with  which  the  Master  Servicer  or any  Servicer  establishes
accounts in the ordinary course of its servicing activities),  the accounts of
which are  insured to the  maximum  extent  permitted  by the FDIC  (each,  an
"Escrow  Account")  and shall  deposit  therein  any  collections  of  amounts
received  with  respect to amounts due for taxes,  assessments,  water  rates,
Standard  Hazard  Insurance  Policy  premiums or any comparable  items for the
account of the Mortgagors. Withdrawals from any Escrow Account may be made (to
the extent  amounts have been  escrowed for such  purpose)  only in accordance
with the applicable  Servicing  Agreement.  Each Servicer shall be entitled to
all  investment  income not  required to be paid to  Mortgagors  on any Escrow
Account maintained by such Servicer.  The Master Servicer shall make (or cause
to be made) to the  extent  provided  in the  applicable  Servicing  Agreement
advances to the extent  necessary in order to effect timely  payment of taxes,
water  rates,  assessments,  Standard  Hazard  Insurance  Policy  premiums  or
comparable  items in connection with the related  Mortgage Loan (to the extent
that the Mortgagor is required,  but fails, to pay such items),  provided that
it has  determined  that the funds so  advanced  are  recoverable  from escrow
payments, reimbursement pursuant to Section 4.02(v) or otherwise.

          (b)  Costs  incurred  by the  Master  Servicer  or by  Servicers  in
effecting  the  timely  payment  of taxes and  assessments  on the  properties
subject  to the  Mortgage  Loans may be added to the  amount  owing  under the
related  Mortgage  Note  where  the  terms  of the  Mortgage  Note so  permit;
provided,  however, that the addition of any such cost shall not be taken into
account  for  purposes  of  calculating  the   distributions  to  be  made  to
Certificateholders.  Such costs,  to the extent  that they are  unanticipated,
extraordinary costs, and not ordinary or routine costs shall be recoverable by
the Master Servicer pursuant to Section 4.02(v).

          Section  9.07.   Termination  of  Servicing  Agreements;   Successor
Servicers.  (a) The Master  Servicer shall be entitled to terminate the rights
and  obligations of any Servicer under the applicable  Servicing  Agreement in
accordance  with the terms and  conditions  of such  Servicing  Agreement  and
without any limitation by virtue of this Agreement; provided, however, that in
the event of termination of any Servicing  Agreement by the Master Servicer or
the related  Servicer,  the Master Servicer shall provide for the servicing of
the related Mortgage Loans as follows: (i) upon any such termination of Option
One as Servicer,  servicing of the related Mortgage Loans shall be transferred
to Aurora, provided that Aurora exercises its option to acquire such servicing
as  provided  below;  (ii) upon any such  termination  of Aurora as  Servicer,
servicing of the related  Mortgage  Loans shall be  transferred to the Special
Servicer,  provided that the Special Servicer  exercises its option to acquire
such  servicing  as provided  below;  and (iii) upon any such  termination  of
Ocwen,  a successor  special  servicer  shall be  appointed as provided in the
Special  Servicing  Agreement.  In each such case,  servicing  of the  related
Mortgage  Loans shall be performed by the  applicable  successor in accordance
with the  provisions of the Servicing  Agreement to which such  successor is a
party.  In the event  that any such  successor  servicer  fails to notify  the
Master Servicer within 15 days of such proposed  transfer  described in clause
(i) or (ii) above of its  intention  to  exercise  its option to acquire  such
servicing and to service the related  Mortgage  Loans in  accordance  with the
terms of the applicable Servicing Agreement, the Master Servicer shall appoint
a  successor  servicer  or special  servicer  or shall  itself (or  through an
Affiliate) act as servicer or special servicer of the related Mortgage Loans.

          Notwithstanding the foregoing provisions to the extent applicable to
termination  of the  rights  and  obligations  of the  Special  Servicer,  the
Directing  Holder,  if any,  shall  have the rights  accorded  to it under the
Special Servicing Agreement.

          (b) If the  Master  Servicer  acts as  Servicer,  it will not assume
liability for the representations and warranties of the Servicer, if any, that
it replaces.  The Master  Servicer  shall use  reasonable  efforts to have the
successor  Servicer assume  liability for the  representations  and warranties
made by the terminated  Servicer in respect of the related Mortgage Loans, and
in the event of any such assumption by the successor Servicer,  the Trustee or
the Master  Servicer,  as  applicable,  may, in the  exercise of its  business
judgment,   release  the   terminated   Servicer   from   liability  for  such
representations and warranties.

          Section   9.08.    Master   Servicer    Liable   for    Enforcement.
Notwithstanding  any Servicing  Agreement,  the Master  Servicer  shall remain
obligated and liable to the Trustee and the  Certificateholders  in accordance
with the  provisions  of this  Agreement,  to the  extent  of its  obligations
hereunder,  without  diminution  of such  obligation or liability by virtue of
such Servicing  Agreements or  arrangements.  The Master Servicer shall ensure
that the Mortgage Loans are serviced in accordance with the provisions of this
Agreement and shall enforce the provisions of each Servicing Agreement for the
benefit of the  Certificateholders.  The Master  Servicer shall be entitled to
enter into any agreement with its Servicers for  indemnification of the Master
Servicer and nothing  contained in this Agreement  shall be deemed to limit or
modify such indemnification.

          Section  9.09. No  Contractual  Relationship  Between  Servicers and
Trustee or Depositor. Any Servicing Agreement that may be entered into and any
other  transactions  or services  relating to the Mortgage  Loans  involving a
Servicer in its capacity as such and not as an  originator  shall be deemed to
be between such Servicer,  the Seller and the Master Servicer, and the Trustee
and the  Depositor  shall  not be deemed  parties  thereto  and shall  have no
claims,  rights,  obligations,  duties or  liabilities  with  respect  to such
Servicer  except as set forth in Section  9.10  hereof.

          Section 9.10.  Assumption of Servicing Agreement by Trustee.  (a) In
the event the  Master  Servicer  shall for any  reason no longer be the Master
Servicer  (including by reason of any Event of Default under this  Agreement),
the Trustee shall  thereupon  assume all of the rights and obligations of such
Master Servicer hereunder and under each Servicing Agreement entered into with
respect to the  Mortgage  Loans.  The Trustee,  its designee or any  successor
master  servicer  appointed by the Trustee shall be deemed to have assumed all
of the Master Servicer's  interest herein and therein to the same extent as if
such Servicing  Agreement had been assigned to the assuming party, except that
the  Master  Servicer  shall not  thereby  be  relieved  of any  liability  or
obligations of the Master  Servicer under such  Servicing  Agreement  accruing
prior to its  replacement  as  Master  Servicer,  and  shall be  liable to the
Trustee, and hereby agrees to indemnify and hold harmless the Trustee from and
against all costs,  damages,  expenses and liabilities  (including  reasonable
attorneys'  fees)  incurred  by the Trustee as a result of such  liability  or
obligations  of the  Master  Servicer  and in  connection  with the  Trustee's
assumption  (but not its  performance,  except  to the  extent  that  costs or
liability  of the Trustee are created or increased as a result of negligent or
wrongful acts or omissions of the Master  Servicer prior to its replacement as
Master   Servicer)   of  the   Master   Servicer's   obligations,   duties  or
responsibilities  thereunder. 

          (b) The Master Servicer that has been terminated shall, upon request
of the  Trustee but at the  expense of such  Master  Servicer,  deliver to the
assuming party all documents and records relating to each Servicing  Agreement
and the related Mortgage Loans and an accounting of amounts collected and held
by it and  otherwise  use its best efforts to effect the orderly and efficient
transfer of each Servicing Agreement to the assuming party.

          Section 9.11. "Due-on-Sale" Clauses;  Assumption Agreements.  To the
extent provided in the applicable Servicing Agreement,  to the extent Mortgage
Loans contain enforceable due-on-sale clauses, the Master Servicer shall cause
the  Servicers  to enforce  such  clauses in  accordance  with the  applicable
Servicing  Agreement.  If  applicable  law  prohibits  the  enforcement  of  a
due-on-sale clause or such clause is otherwise not enforced in accordance with
the applicable Servicing Agreement, and, as a consequence,  a Mortgage Loan is
assumed,  the original  Mortgagor may be released from liability in accordance
with the applicable Servicing Agreement.

          Section 9.12.  Release of Mortgage Files. (a) Upon becoming aware of
the  payment  in full of any  Mortgage  Loan,  or the  receipt  by the  Master
Servicer of a notification  that payment in full has been escrowed in a manner
customary  for such  purposes  for payment to  Certificateholders  on the next
Distribution  Date,  the Master  Servicer  will, or will cause the  applicable
Servicer to,  promptly  notify the Trustee (or the applicable  Custodian) by a
certification  (which  certification  shall  include a statement to the effect
that all amounts received in connection with such payment that are required to
be deposited  in the  Collection  Account  maintained  by the Master  Servicer
pursuant  to Section  4.01 have been or will be so  deposited)  of a Servicing
Officer and shall request the Trustee or the applicable Custodian,  to deliver
to the applicable  Servicer the related  Mortgage  File.  Upon receipt of such
certification and request,  the Trustee or the applicable  Custodian (with the
consent,  and at the direction of the  Trustee),  shall  promptly  release the
related Mortgage File to the applicable Servicer and the Trustee shall have no
further  responsibility  with  regard  to such  Mortgage  File.  Upon any such
payment in full, the Master Servicer is authorized,  and each Servicer, to the
extent such  authority is delegated  to such  Servicer by the Master  Servicer
under the applicable Servicing Agreement, is authorized, to give, as agent for
the Trustee,  as the  mortgagee  under the Mortgage  that secured the Mortgage
Loan,  an  instrument  of  satisfaction  (or  assignment  of mortgage  without
recourse)  regarding the  Mortgaged  Property  subject to the Mortgage,  which
instrument  of  satisfaction  or  assignment,  as the  case  may be,  shall be
delivered to the Person or Persons  entitled  thereto against receipt therefor
of such payment,  it being understood and agreed that no expenses  incurred in
connection with such instrument of satisfaction or assignment, as the case may
be, shall be chargeable to the Collection  Account.  (b) From time to time and
as  appropriate  for the servicing or  foreclosure of any Mortgage Loan and in
accordance  with Accepted  Servicing  Practices and the  applicable  Servicing
Agreement,  the Trustee shall execute such  documents as shall be prepared and
furnished  to the Trustee by the Master  Servicer,  or by a Servicer  (in form
reasonably  acceptable to the Trustee) and as are necessary to the prosecution
of any such proceedings.  The Trustee or the Custodian, shall, upon request of
the Master  Servicer,  or of a  Servicer,  and  delivery to the Trustee or the
applicable  Custodian,  of a  trust  receipt  signed  by a  Servicing  Officer
substantially in the form of Exhibit C, release the related Mortgage File held
in its  possession  or  control  to the  Master  Servicer  (or the  applicable
Servicer). Such trust receipt shall obligate the Master Servicer or applicable
Servicer  to  return  the  Mortgage  File  to the  Trustee  or  Custodian,  as
applicable,  when the need  therefor  by the  Master  Servicer  or  applicable
Servicer no longer  exists unless the Mortgage  Loan shall be  liquidated,  in
which case,  upon receipt of a certificate of a Servicing  Officer  similar to
that  herein  above  specified,  the trust  receipt  shall be  released by the
Trustee  or the  Custodian,  as  applicable,  to the Master  Servicer  (or the
applicable Servicer).

          Section 9.13.  Documents,  Records and Funds in Possession of Master
Servicer To Be Held for Trustee.  (a) The Master Servicer shall  transmit,  or
cause the applicable  Servicer to transmit,  to the Trustee such documents and
instruments coming into the possession of the Master Servicer or such Servicer
from time to time as are  required by the terms  hereof to be delivered to the
Trustee. Any funds received by the Master Servicer or by a Servicer in respect
of any Mortgage Loan or which  otherwise are collected by the Master  Servicer
or by a Servicer as Liquidation  Proceeds or Insurance  Proceeds in respect of
any  Mortgage  Loan  shall  be held for the  benefit  of the  Trustee  and the
Certificateholders  subject  to the  Master  Servicer's  right  to  retain  or
withdraw  from the  Collection  Account  the  Master  Servicing  Fee and other
amounts  provided  in this  Agreement,  and to the right of each  Servicer  to
retain its Servicing Fee as provided in the  applicable  Servicing  Agreement.
The Master Servicer shall, and shall (to the extent provided in the applicable
Servicing Agreement) cause each Servicer to, provide access to information and
documentation  regarding  the Mortgage  Loans to the  Trustee,  its agents and
accountants  at any time upon  reasonable  request and during normal  business
hours, and to Certificateholders that are savings and loan associations, banks
or insurance  companies,  the Office of Thrift  Supervision,  the FDIC and the
supervisory  agents and examiners of such Office and  Corporation or examiners
of any other federal or state banking or insurance  regulatory authority if so
required by  applicable  regulations  of the Office of Thrift  Supervision  or
other regulatory authority, such access to be afforded without charge but only
upon  reasonable  request in writing and during normal  business  hours at the
offices of the Master Servicer  designated by it. In fulfilling such a request
the Master  Servicer shall not be responsible  for determining the sufficiency
of such information.

          (b) All Mortgage Files and funds  collected or held by, or under the
control of, the Master Servicer,  or any Servicer,  in respect of any Mortgage
Loans,  whether from the collection of principal and interest payments or from
Liquidation  Proceeds  or  Insurance  Proceeds,  shall  be held by the  Master
Servicer,  or by any  Servicer,  for  and on  behalf  of the  Trustee  and the
Certificateholders  and shall be and remain the sole and exclusive property of
the Trustee;  provided,  however,  that the Master  Servicer and each Servicer
shall be  entitled  to setoff  against,  and deduct  from,  any such funds any
amounts  that are  properly  due and  payable to the Master  Servicer  or such
Servicer under this Agreement or the applicable Servicing Agreement.

          (c) The Master Servicer hereby  acknowledges  that concurrently with
the execution of this Agreement,  the Trustee shall own or, to the extent that
a court of competent  jurisdiction  shall deem the  conveyance of the Mortgage
Loans from the Seller to the Depositor  not to constitute a sale,  the Trustee
shall have a security interest in the Mortgage Loans and in all Mortgage Files
representing such Mortgage Loans and in all funds now or hereafter held by, or
under the control of, a Servicer or the Master  Servicer that are collected by
any Servicer or the Master  Servicer in  connection  with the Mortgage  Loans,
whether as  scheduled  installments  of  principal  and interest or as full or
partial  prepayments  of principal or interest or as  Liquidation  Proceeds or
Insurance  Proceeds or  otherwise,  and in all proceeds of the  foregoing  and
proceeds  of  proceeds  (but  excluding  any fee or other  amounts  to which a
Servicer is entitled under its Servicing Agreement,  or the Master Servicer or
the Depositor is entitled to hereunder);  and the Master  Servicer agrees that
so long as the Mortgage  Loans are  assigned to and held by the  Trustee,  all
documents or instruments  constituting  part of the Mortgage  Files,  and such
funds relating to the Mortgage Loans which come into the possession or custody
of, or which are  subject  to the  control  of,  the  Master  Servicer  or any
Servicer  shall be held by the Master  Servicer  or such  Servicer  for and on
behalf of the  Trustee  as the  Trustee's  agent and bailee  for  purposes  of
perfecting  the  Trustee's  security  interest  therein  as  provided  by  the
applicable  Uniform  Commercial  Code or other laws.  (d) The Master  Servicer
agrees that it shall not, and shall not  authorize  any  Servicer to,  create,
incur or subject any Mortgage  Loans,  or any funds that are  deposited in any
custodial account, Escrow Account or the Collection Account, or any funds that
otherwise are or may become due or payable to the Trustee, to any claim, lien,
security  interest,  judgment,  levy, writ of attachment or other encumbrance,
nor assert by legal action or otherwise  any claim or right of setoff  against
any Mortgage Loan or any funds collected on, or in connection with, a Mortgage
Loan.  Section  9.14.  _____  Representations  and  Warranties  of the  Master
Servicer.  (a) The Master  Servicer  hereby  represents  and  warrants  to the
Depositor and the Trustee,  for the benefit of the  Certificateholders,  as of
the Closing Date that:

                    (i) it is validly  existing and in good standing under the

          transact any and all business  contemplated by this Agreement and to
          execute,  deliver and comply with its obligations under the terms of
          this  Agreement,  the execution,  delivery and  performance of which
          have been duly authorized by all necessary  corporate  action on the
          part of the Master Servicer;

                    (ii) the execution  and delivery of this  Agreement by the
          Master Servicer and its performance and compliance with the terms of
          this Agreement will not (A) violate the Master Servicer's charter or
          bylaws,  (B) violate  any law or  regulation  or any  administrative
          decree or order to which it is subject or (C)  constitute  a default
          (or an event  which,  with notice or lapse of time,  or both,  would
          constitute  a  default)  under,  or result  in the  breach  of,  any
          material contract, agreement or other instrument to which the Master
          Servicer  is a party or by which it is bound or to which  any of its
          assets  are  subject,  which  violation,  default  or  breach  would
          materially  and adversely  affect the Master  Servicer's  ability to
          perform its obligations  under this Agreement;  

                    (iii)   this   Agreement    constitutes,    assuming   due
          authorization, execution and delivery hereof by the other respective
          parties hereto, a legal,  valid and binding obligation of the Master
          Servicer,  enforceable  against  it in  accordance  with  the  terms
          hereof,  except as such  enforcement  may be limited by  bankruptcy,
          insolvency, reorganization,  moratorium and other laws affecting the
          enforcement of creditors'  rights in general,  and by general equity
          principles  (regardless of whether such enforcement is considered in
          a proceeding in equity or at law);  

                    (iv) the Master Servicer is not in default with respect to
          any order or decree of any court or any order or  regulation  of any
          federal,  state, municipal or governmental agency to the extent that
          any  such  default  would   materially  and  adversely   affect  its
          performance hereunder;  

                    (v) the Master  Servicer is not a party to or bound by any
          agreement or instrument or subject to any charter  provision,  bylaw

          injunction,  decree,  law or  regulation  that  may  materially  and
          adversely  affect its  ability  as Master  Servicer  to perform  its
          obligations under this Agreement or that requires the consent of any
          third person to the execution of this  Agreement or the  performance
          by the Master Servicer of its obligations under this Agreement;

          which would  prohibit its entering into this Agreement or performing
          its obligations under this Agreement;  

                    (vii) the Master  Servicer,  or an  affiliate  thereof the
          primary   business  of  which  is  the  servicing  of   conventional
          residential   mortgage  loans,   is  an  FNMA-  and   FHLMC-approved
          seller/servicer; 

                    (viii) no consent, approval, authorization or order of any
          court or governmental  agency or body is required for the execution,
          delivery and  performance by the Master Servicer of or compliance by

          obtained;

          (b)  It is  understood  and  agreed  that  the  representations  and
warranties  set forth in this Section  9.14 shall  survive the  execution  and
delivery of this Agreement.  The Master Servicer shall indemnify the Depositor
and the Trustee and hold them harmless against any loss,  damages,  penalties,
fines,  forfeitures,  legal fees and related costs, judgments, and other costs
and expenses resulting from any claim,  demand,  defense or assertion based on
or  grounded  upon,  or  resulting  from,  a breach of the  Master  Servicer's
representations and warranties  contained in Section 9.14(a). It is understood
and agreed that the  enforcement of the obligation of the Master  Servicer set
forth in this Section to indemnify  the  Depositor and the Trustee as provided
in this  Section  constitutes  the sole  remedy  (other  than as set  forth in
Section  6.14) of the  Depositor  and the Trustee,  respecting a breach of the
foregoing  representations and warranties.  Such indemnification shall survive
any termination of the Master Servicer as Master Servicer  hereunder,  and any
termination of this Agreement.

          Any cause of action  against  the  Master  Servicer  relating  to or
arising out of the breach of any  representations  and warranties made in this
Section  shall accrue upon  discovery of such breach by either the  Depositor,
the  Master  Servicer  or the  Trustee  or notice  thereof  by any one of such
parties to the other parties.

          (c)  It is  understood  and  agreed  that  the  representations  and
warranties of the Depositor  set forth in Sections  2.03(a)  through (f) shall
survive the execution  and delivery of this  Agreement.  The  Depositor  shall
indemnify the Master Servicer and hold it harmless against any loss,  damages,
penalties,  fines,  forfeitures,  legal fees and related costs, judgments, and
other  costs  and  expenses  resulting  from any  claim,  demand,  defense  or
assertion  based on or  grounded  upon,  or  resulting  from,  a breach of the
Depositor's  representations  and  warranties  contained  in Sections  2.03(a)
through (f) hereof.  It is understood  and agreed that the  enforcement of the
obligation  of the Depositor set forth in this Section to indemnify the Master
Servicer as provided in this Section constitutes the sole remedy of the Master
Servicer  respecting  a breach by the  Depositor  of the  representations  and
warranties in Sections 2.03(a) through (f) hereof.

          Any cause of action against the Depositor relating to or arising out
of the breach of the  representations  and warranties made in Sections 2.03(a)
through (f) hereof  shall  accrue upon  discovery of such breach by either the
Depositor or the Master  Servicer or notice thereof by any one of such parties
to the other parties.

          Section  9.15.  Closing  Certificate  and Opinion.  On or before the
Closing Date, the Master Servicer shall cause to be delivered to the Depositor
and Lehman  Brothers  Inc. an Opinion of Counsel,  dated the Closing  Date, in
form  and  substance  reasonably  satisfactory  to the  Depositor  and  Lehman
Brothers  Inc.,  as to the due  authorization,  execution and delivery of this
Agreement by the Master Servicer and the enforceability thereof.

          Section 9.16. Standard Hazard and Flood Insurance Policies. For each
Mortgage  Loan,  the Master  Servicer shall maintain or cause to be maintained
standard fire and casualty  insurance and, where applicable,  flood insurance,
all in  accordance  with the  provisions  of this  Agreement  and the  related
Servicing  Agreement,  as  applicable.  It is understood  and agreed that such
insurance  shall be with insurers  meeting the  eligibility  requirements  set
forth in the  applicable  Servicing  Agreement and that no earthquake or other
additional insurance is to be required of any Mortgagor or to be maintained on
property  acquired in respect of a defaulted loan, other than pursuant to such
applicable  laws and regulations as shall at any time be in force and as shall
require such additional insurance.

          Pursuant  to  Section  4.01,  any  amounts  collected  by the Master
Servicer, or by any Servicer, under any insurance policies maintained pursuant
to this Section 9.16 (other than amounts to be applied to the  restoration  or
repair of the  property  subject to the  related  Mortgage  or released to the
Mortgagor in accordance  with the  applicable  Servicing  Agreement)  shall be
deposited  into the  Collection  Account,  subject to  withdrawal  pursuant to
Section  4.02.  Any cost  incurred by the Master  Servicer or any  Servicer in
maintaining any such insurance if the Mortgagor  defaults in its obligation to
do so shall be added to the amount  owing  under the  Mortgage  Loan where the
terms of the Mortgage Loan so permit; provided,  however, that the addition of
any such cost shall not be taken into account for purposes of calculating  the
distributions to be made to Certificateholders and shall be recoverable by the
Master Servicer or such Servicer pursuant to Section 4.02(v).

          Section 9.17.  Presentment of Claims and Collection of Proceeds. The
Master Servicer shall, or shall cause each Servicer (to the extent provided in
the applicable  Servicing  Agreement) to, prepare and present on behalf of the
Trustee and the  Certificateholders  all claims under the  Insurance  Policies
with  respect to the Mortgage  Loans,  and take such  actions  (including  the
negotiation,  settlement, compromise or enforcement of the insured's claim) as
shall be  necessary  to realize  recovery  under such  policies.  Any proceeds
disbursed to the Master  Servicer (or  disbursed to a Servicer and remitted to
the Master  Servicer)  in respect of such  policies or bonds shall be promptly
deposited  in the  Collection  Account upon  receipt,  except that any amounts
realized  that are to be applied to the repair or  restoration  of the related
Mortgaged  Property as a condition  requisite to the presentation of claims on
the related Mortgage Loan to the insurer under any applicable Insurance Policy
need not be so deposited (or remitted).

          Section  9.18.   Maintenance  of  the  Primary  Mortgage   Insurance
Policies.  (a) The Master  Servicer  shall not take,  or permit  any  Servicer
(consistent with the applicable  Servicing Agreement) to take, any action that
would result in noncoverage  under any applicable  Primary Mortgage  Insurance
Policy of any loss  which,  but for the  actions of such  Master  Servicer  or
Servicer,  would have been covered  thereunder.  The Master Servicer shall use
its best  reasonable  efforts  to keep in force and  effect,  or to cause each
Servicer  to keep in force and effect (to the extent  that the  Mortgage  Loan
requires the Mortgagor to maintain such insurance), primary mortgage insurance
applicable to each Mortgage  Loan in  accordance  with the  provisions of this
Agreement  and the related  Servicing  Agreement,  as  applicable.  The Master
Servicer  shall not, and shall not permit any Servicer to, cancel or refuse to
renew any such Primary Mortgage Insurance Policy that is in effect at the date
of the  initial  issuance  of the  Certificates  and is required to be kept in
force hereunder except in accordance with the provisions of this Agreement and
the related Servicing Agreement, as applicable. 

          (b) The Master Servicer agrees to present, or to cause each Servicer
to present, on behalf of the Trustee and the Certificateholders, claims to the
insurer under any Primary Mortgage  Insurance Policies and, in this regard, to
take such reasonable action as shall be necessary to permit recovery under any
Primary  Mortgage  Insurance  Policies  respecting  defaulted  Mortgage Loans.
Pursuant to Section 4.01, any amounts  collected by the Master Servicer or any
Servicer under any Primary Mortgage  Insurance  Policies shall be deposited in
the Collection Account, subject to withdrawal pursuant to Section 4.02.

          Section  9.19.  Trustee To Retain  Possession  of Certain  Insurance
Policies and Documents.  The Trustee (or its custodian, if any, as directed by
the  Trustee),  shall retain  possession  and custody of the  originals of the
Primary Mortgage  Insurance Policies or certificate of insurance if applicable
and any certificates of renewal as to the foregoing as may be issued from time
to time as contemplated by this Agreement.  Until all amounts distributable in
respect  of the  Certificates  have been  distributed  in full and the  Master
Servicer  otherwise has fulfilled its obligations  under this  Agreement,  the
Trustee (or its  custodian,  if any, as  directed by the  Trustee)  shall also
retain  possession  and custody of each Mortgage  File in accordance  with and
subject to the terms and  conditions of this  Agreement.  The Master  Servicer
shall  promptly  deliver  or  cause to be  delivered  to the  Trustee  (or its
custodian,  if any, as directed by the Trustee), upon the execution or receipt
thereof the  originals  of the Primary  Mortgage  Insurance  Policies  and any
certificates of renewal thereof,  and such other documents or instruments that
constitute  portions of the Mortgage File that come into the possession of the
Master Servicer from time to time.

          Section 9.20.  Realization Upon Defaulted Mortgage Loans. Subject to
the provisions of the Special Servicing  Agreement,  the Master Servicer shall
use its  reasonable  best  efforts  to, or to cause the Special  Servicer  to,
foreclose  upon,  repossess or otherwise  comparably  convert the ownership of
Mortgaged  Properties  securing  such of the  Mortgage  Loans as come into and
continue in default and as to which no satisfactory  arrangements  can be made
for collection of delinquent  payments,  all in accordance with the applicable
Servicing Agreement.

          Section  9.21.  Compensation  to the  Master  Servicer.  The  Master
Servicer shall (i) be entitled, at its election,  either (a) to pay itself the
Master  Servicing Fee, as reduced  pursuant to Section 5.05, in respect of the
Mortgage  Loans out of any Mortgagor  payment on account of interest  prior to
the deposit of such payment in the  Collection  Account it maintains or (b) to
withdraw from the  Collection  Account,  subject to Section  5.05,  the Master
Servicing Fee to the extent permitted by Section 4.02(iv). The Master Servicer
shall also be entitled,  at its election,  either (a) to pay itself the Master
Servicing Fee in respect of each  delinquent  Mortgage Loan master serviced by
it out of  Liquidation  Proceeds  in  respect of such  Mortgage  Loan or other
recoveries with respect thereto to the extent permitted in Section 4.02 or (b)
to withdraw from the Collection  Account it maintains the Master Servicing Fee
in respect of each Liquidated  Mortgage Loan to the extent of such Liquidation
Proceeds  or other  recoveries,  to the  extent  permitted  by  Section  4.02.
Servicing  compensation  in the form of assumption  fees, if any, late payment
charges, as collected,  if any, or otherwise (but not including any Prepayment
Penalty  Amount) shall be retained by the Master  Servicer (or the  applicable
Servicer) and shall not be deposited in the Collection  Account. If the Master
Servicer  does not  retain  or  withdraw  the  Master  Servicing  Fee from the
Collection  Account as provided herein,  the Master Servicer shall be entitled
to direct the Trustee to pay the Master  Servicing Fee to such Master Servicer
by withdrawal  from the  Certificate  Account to the extent that payments have
been  received  with  respect  to the  applicable  Mortgage  Loan.  The Master
Servicer  shall be required to pay all expenses  incurred by it in  connection
with its  activities  hereunder  and shall not be  entitled  to  reimbursement
therefor  except as provided in this Agreement.  Pursuant to Section  4.01(e),
all income and gain  realized from any  investment of funds in the  Collection
Account  shall  be for  the  benefit  of the  Master  Servicer  as  additional
compensation.  The  provisions  of  this  Section  9.21  are  subject  to  the
provisions of Section 6.14(b).  

          Section 9.22. REO Property. (a) In the event the Trust Fund acquires
ownership  of any REO Property in respect of any  Mortgage  Loan,  the deed or
certificate  of sale shall be issued to the  Trustee,  or to its  nominee,  on
behalf of the  Certificateholders.  Subject to the  provisions  of the Special
Servicing Agreement, the Master Servicer shall use its reasonable best efforts
to sell,  or, to the extent  provided in the applicable  Servicing  Agreement,
cause the Special  Servicer to sell,  any REO  Property  as  expeditiously  as
possible and in  accordance  with the  provisions  of this  Agreement  and the
related Servicing Agreement, as applicable,  but in all events within the time
period, and subject to the conditions set forth in Article X hereof.  Pursuant
to its efforts to sell such REO Property,  the Master  Servicer  shall protect
and conserve, or cause the Special Servicer to protect and conserve,  such REO
Property  in the manner and to such extent  required by the Special  Servicing
Agreement,  subject to Article X hereof. 

          (b) The Master  Servicer  shall deposit or cause to be deposited all
funds  collected  and  received in  connection  with the  operation of any REO
Property in the Collection Account it maintains.

          (c) The Master Servicer and the applicable Servicer,  upon the final
disposition of any REO Property,  shall be entitled to  reimbursement  for any
related  unreimbursed  Advances as well as any unpaid Master Servicing Fees or
Servicing Fees from Liquidation Proceeds received in connection with the final
disposition  of such  REO  Property;  provided,  that  any  such  unreimbursed
Advances as well as any unpaid Master  Servicing Fees or Servicing Fees may be
reimbursed or paid, as the case may be, prior to final disposition, out of any
net rental income or other net amounts derived from such REO Property. 

          (d) The Liquidation  Proceeds from the final  disposition of the REO
Property,  net of any  payment  to the  Master  Servicer  and  the  applicable
Servicer as provided above and in the Special  Servicing  Agreement,  shall be
deposited in the Collection  Account on or prior to the Determination  Date in
the month  following  receipt  thereof (and the Master  Servicer shall provide
prompt  written  notice to the Trustee  upon such  deposit) and be remitted by
wire transfer in immediately  available  funds to the Trustee for deposit into
the Certificate Account on the next succeeding Deposit Date.

          Section 9.23.  Preparation of Tax Returns and Other Reports. (a) The
Master  Servicer  shall prepare or cause to be prepared on behalf of the Trust
Fund,  based upon  information  calculated in accordance  with this  Agreement
pursuant to instructions  given by the Depositor,  and the Trustee shall file,
federal tax returns and  appropriate  state  income tax returns and such other
returns as may be required by applicable  law relating to the Trust Fund,  and
the Trustee shall forward copies to the Depositor of all such returns and Form
1099 information and such other information  within the control of the Trustee
as the Depositor may reasonably request in writing,  and shall forward to each
Certificateholder  such forms and furnish such information  within the control
of the  Trustee as are  required  by the Code and the REMIC  Provisions  to be
furnished  to them,  and will  prepare  and file  annual  reports  required by
applicable  state  authorities,  will file copies of this  Agreement  with the
appropriate  state  authorities as may be required by applicable law, and will
prepare and disseminate to Certificateholders  Form 1099 (or otherwise furnish
information  within the  control of the  Trustee)  to the extent  required  by
applicable  law.  The Master  Servicer  will  indemnify  the  Trustee  for any
liability of or assessment against the Trustee resulting from any error in any
of such tax or information  returns  resulting from errors in the  information
provided  by such Master  Servicer  (other  than  information  that is derived
solely from information provided by a Servicer).

          (b) The Master  Servicer  shall  prepare and file with the  Internal
Revenue  Service  ("IRS"),  on behalf of the Trust Fund, an application on IRS
Form SS-4.  The Master  Servicer,  upon  receipt from the IRS of the Notice of
Taxpayer Identification Number Assigned, shall promptly forward a copy of such
notice to the Trustee and the Depositor.

          (c) The Depositor  shall prepare or cause to be prepared the initial
current report on Form 8-K and thereafter the Master  Servicer will prepare or
cause to be  prepared  Form  10-Ks and Form 10-Qs (if  necessary),  or monthly
current  reports on Form 8-K, on behalf of the Trust Fund,  as may be required
by applicable law, for filing with the Securities and Exchange Commission (the
"SEC").  The Trustee  will sign each such  report on behalf of the Trust.  The
Master  Servicer  will  forward  a copy of each such  report to the  Depositor
promptly  after such report has been filed with the SEC.  The Master  Servicer
agrees to use its best  efforts to seek to  terminate  such filing  obligation
after the period during which such filings are required  under the  Securities
Exchange Act of 1934. Promptly after filing a Form 15 or other applicable form
with the SEC in connection  with such  termination,  the Master Servicer shall
deliver  to the  Depositor  a copy  of  such  form  together  with  copies  of
confirmations  of receipt by the SEC of each report filed  therewith on behalf
of the Trust Fund.  

          Section  9.24.  Reports to the  Trustee.  (a) Not later than 30 days
after each Distribution Date, the Master Servicer shall forward to the Trustee
a statement,  deemed to have been  certified by a Servicing  Officer,  setting
forth the status of the Collection  Account  maintained by the Master Servicer
as of the close of business on the related Distribution Date,  indicating that
all distributions required by this Agreement to be made by the Master Servicer
have  been  made (or if any  required  distribution  has not been  made by the
Master  Servicer,  specifying the nature and status thereof) and showing,  for
the period  covered by such  statement,  the  aggregate  of deposits  into and
withdrawals  from the Collection  Account  maintained by the Master  Servicer.
Copies of such  statement  shall be  provided  by the Master  Servicer  to the
Depositor,    Attention:    Contract   Finance,   and,   upon   request,   any
Certificateholders  (or by the Trustee at the Master Servicer's expense if the
Master  Servicer  shall fail to provide  such  copies  (unless  (i) the Master
Servicer  shall have failed to provide the Trustee with such statement or (ii)
the Trustee shall be unaware of the Master Servicer's  failure to provide such
statement)).

          (b) Not later than two Business  Days  following  each  Distribution
Date,  the Master  Servicer  shall  deliver to the  Person  designated  by the
Depositor,  in a format  consistent with other electronic loan level reporting
supplied by the Master Servicer in connection with similar transactions, "loan
level"  information  with  respect  to the  Mortgage  Loans as of the  related
Determination  Date, to the extent that such  information has been provided to
the Master Servicer by the Servicers or by the Depositor.

          Section 9.25. Annual Officer's Certificate as to Compliance. (a) The
Master  Servicer  shall  deliver to the  Trustee  and the Rating  Agency on or
before  May  31 of  each  year,  commencing  on May  31,  1999,  an  Officer's
Certificate,  certifying  that  with  respect  to  the  period  ending  on the
immediately  preceding  December 31; such  Servicing  Officer has reviewed the
activities  of such Master  Servicer  during the  preceding  calendar  year or
portion thereof and its performance under this Agreement;  to the best of such
Servicing Officer's knowledge,  based on such review, such Master Servicer has
performed and fulfilled its duties,  responsibilities  and  obligations  under
this Agreement in all material respects throughout such year, or, if there has
been a default in the  fulfillment  of any such  duties,  responsibilities  or
obligations,  specifying each such default known to such Servicing Officer and
the nature and  status  thereof,  nothing  has come to the  attention  of such
Servicing  Officer to lead such Servicing Officer to believe that any Servicer
has failed to perform  any of its  duties,  responsibilities  and  obligations
under its Servicing  Agreement in all material respects  throughout such year,
or, if there has been a material  default in the performance or fulfillment of
any such duties, responsibilities or obligations, specifying each such default
known to such  Servicing  Officer and the nature and status  thereof,  and the
Master  Servicer  has  received  from each  Servicer  such  Servicer's  annual
certificate of compliance and a copy of such  Servicer's  annual audit report,
in each case to the extent required under the applicable  Servicing Agreement,
or, if any such  certificate  or report  has not been  received  by the Master
Servicer,  the Master Servicer is using its best reasonable  efforts to obtain
such certificate or report.

          (b)   Copies  of  such   statements   shall  be   provided   to  any
Certificateholder  upon request,  by the Master  Servicer or by the Trustee at
the Master  Servicer's  expense if the Master  Servicer failed to provide such
copies  (unless  (i) the  Master  Servicer  shall have  failed to provide  the
Trustee with such statement or (ii) the Trustee shall be unaware of the Master
Servicer's failure to provide such statement).

          Section 9.26. Annual Independent  Accountants'  Servicing Report. If
the Master  Servicer  has,  during the  course of any  fiscal  year,  directly
serviced any of the Mortgage  Loans,  then the Master  Servicer at its expense
shall cause a  nationally  recognized  firm of  independent  certified  public
accountants  to furnish a statement to the Trustee,  the Rating Agency and the
Depositor on or before May 31 of each year,  commencing on May 31, 1999 to the
effect that,  with respect to the most recently  ended fiscal year,  such firm
has examined certain records and documents  relating to the Master  Servicer's
performance of its servicing  obligations under this Agreement and pooling and
servicing and trust agreements in material  respects similar to this Agreement
and to each  other  and  that,  on the  basis  of such  examination  conducted
substantially in compliance with the audit program for mortgages  serviced for
FHLMC or the Uniform Single  Attestation  Program for Mortgage  Bankers,  such
firm is of the  opinion  that  the  Master  Servicer's  activities  have  been
conducted in compliance  with this  Agreement,  or that such  examination  has
disclosed no material items of noncompliance except for (i) such exceptions as
such firm  believes to be  immaterial,  (ii) such other  exceptions as are set
forth in such  statement  and (iii) such  exceptions  that the Uniform  Single
Attestation  Program for Mortgage  Bankers or the Audit  Program for Mortgages
Serviced by FHLMC requires it to report.  Copies of such  statements  shall be
provided to any  Certificateholder  upon request by the Master Servicer, or by
the Trustee at the expense of the Master Servicer if the Master Servicer shall
fail to provide  such copies.  If such report  discloses  exceptions  that are
material, the Master Servicer shall advise the Trustee whether such exceptions
have been or are susceptible of cure, and will take prompt action to do so.

          Section  9.27.  Merger or  Consolidation.  Any Person into which the
Master Servicer may be merged or  consolidated,  or any Person  resulting from
any merger,  conversion,  other change in form or  consolidation  to which the
Master Servicer shall be a party, or any Person  succeeding to the business of
the Master Servicer,  shall be the successor to the Master Servicer hereunder,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto,  anything  herein to the contrary  notwithstanding;
provided,  however,  that the  successor  or  resulting  Person to the  Master
Servicer  shall be a Person that shall be  qualified  and  approved to service
mortgage  loans for FNMA or FHLMC and shall  have a net worth of not less than
$15,000,000.

          Section 9.28.  Resignation of Master  Servicer.  Except as otherwise
provided in  Sections  9.27 and 9.29  hereof,  the Master  Servicer  shall not
resign from the  obligations  and duties hereby imposed on it unless it or the
Trustee  determines that the Master  Servicer's duties hereunder are no longer
permissible  under  applicable  law or are in  material  conflict by reason of
applicable law with any other activities carried on by it and cannot be cured.
Any such determination permitting the resignation of the Master Servicer shall
be evidenced by an Opinion of Counsel that shall be Independent to such effect
delivered to the Trustee. No such resignation shall become effective until the
Trustee shall have assumed,  or a successor  master  servicer  shall have been
appointed  by the Trustee and until such  successor  shall have  assumed,  the
Master  Servicer's  responsibilities  and  obligations  under this  Agreement.
Notice of such  resignation  shall be given promptly by the Master Servicer to
the Depositor.

          Section  9.29.  Assignment  or  Delegation  of Duties by the  Master
Servicer.  Except as expressly  provided herein, the Master Servicer shall not
assign or transfer any of its rights,  benefits or privileges hereunder to any
other Person,  or delegate to or subcontract with, or authorize or appoint any
other  Person to perform any of the duties,  covenants  or  obligations  to be
performed by the Master Servicer hereunder; provided, however, that the Master
Servicer  shall  have the right  without  the  prior  written  consent  of the
Trustee,  the  Depositor  or the  Rating  Agency to  delegate  or assign to or
subcontract  with or authorize or appoint an Affiliate of the Master  Servicer
to perform and carry out any duties,  covenants or obligations to be performed
and carried out by the Master Servicer hereunder.  In no case, however,  shall
any such  delegation,  subcontracting  or  assignment  to an  Affiliate of the
Master Servicer relieve the Master Servicer of any liability hereunder. Notice
of such permitted assignment shall be given promptly by the Master Servicer to
the  Depositor and the Trustee.  If,  pursuant to any  provision  hereof,  the
duties of the Master Servicer are transferred to a successor  master servicer,
the entire amount of the Master Servicing Fees and other compensation  payable
to the  Master  Servicer  pursuant  hereto,  including  amounts  payable to or
permitted  to be  retained or  withdrawn  by the Master  Servicer  pursuant to
Section 9.21 hereof,  shall  thereafter  be payable to such  successor  master
servicer.

          Section  9.30.  Limitation  on Liability of the Master  Servicer and
Others.  Neither  the  Master  Servicer  nor any of the  directors,  officers,
employees or agents of the Master Servicer shall be under any liability to the
Trustee or the  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 Master  Servicer  or any such  person  against  any  liability  that would
otherwise be imposed by reason of willful misfeasance, bad faith or negligence
in its  performance  of its duties or by reason of reckless  disregard for its
obligations  and duties  under this  Agreement.  The Master  Servicer  and any
director,  officer,  employee or agent of the Master Servicer 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 Master Servicer
shall be under no  obligation  to appear  in,  prosecute  or defend  any legal
action that is not  incidental  to its duties to master  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 Master Servicer 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
Master  Servicer  shall  be  entitled  to be  reimbursed  therefor  out of the
Collection Account it maintains as provided by Section 4.02.

          The Master Servicer shall not be liable for any acts or omissions of
any Servicer.  In particular,  the Master Servicer shall not be liable for any
servicing errors or  interruptions  resulting from any failure of any Servicer
to  maintain  computer  and  other  information  systems  that  are  year-2000
compliant.

          Section  9.31.  Indemnification;   Third-Party  Claims.  The  Master
Servicer  agrees to indemnify  the  Depositor  and the Trustee,  and hold them
harmless against any and all claims, losses,  penalties,  fines,  forfeitures,
legal fees and related costs, judgments, and any other costs, liability,  fees
and expenses that the Depositor and the Trustee may sustain as a result of the
failure of the Master  Servicer to perform  its duties and master  service the
Mortgage Loans in compliance with the terms of this  Agreement.  The Depositor
and the Trustee  shall  immediately  notify the Master  Servicer if a claim is
made by a third party with respect to this  Agreement  or the  Mortgage  Loans
entitling the Depositor or the Trustee to indemnification hereunder, whereupon
the Master  Servicer  shall  assume 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 them in respect of such claim.

the Trustee to treat the Trust Fund as a REMIC under the Code.  Such  election
will be made on Form  1066 or other  appropriate  federal  tax or  information
return for the  taxable  year ending on the last day of the  calendar  year in
which the  Certificates  are issued.  For the purposes of such election,  each
Class A Certificate  and each Class B  Certificate  shall be designated as the
"regular  interests"  in the  REMIC  and the  Class  R  Certificate  shall  be
designated as the "residual interest" in the REMIC.

          (b) The Closing Date is hereby  designated  as the "Startup  Day" of
each REMIC within the meaning of section 86OG(a)(9) of the Code.

          (c) The Master  Servicer shall pay any and all tax related  expenses
(not  including  taxes)  of  each  REMIC,  including  but not  limited  to any
professional  fees or  expenses  related  to audits or any  administrative  or
judicial  proceedings  with  respect to such REMIC that  involve the  Internal
Revenue Service or state tax authorities, but only to the extent that (i) such
expenses are  ordinary or routine  expenses,  including  expenses of a routine
audit but not expenses of  litigation  (except as described in (ii));  or (ii)
such expenses or liabilities  (including taxes and penalties) are attributable
to the negligence or willful  misconduct of the Master  Servicer in fulfilling
its duties hereunder (including its duties as tax return preparer). The Master
Servicer shall be entitled to reimbursement of expenses to the extent provided
in clause (i) above from the Collection Account. 

          (d) The Master  Servicer shall  prepare,  and the Trustee shall sign
and file, all of each REMIC's federal and state tax and information returns as
such REMIC's direct representative.  The expenses of preparing and filing such
returns shall be borne by the Master  Servicer.  

          (e) The Master  Servicer  shall act as Tax  Matters  Person for each
REMIC.  The Master  Servicer or its designee  shall  perform on behalf of each
REMIC  all   reporting   and  other  tax   compliance   duties  that  are  the
responsibility  of such REMIC under the Code, the REMIC  Provisions,  or other
compliance  guidance  issued by the Internal  Revenue  Service or any state or
local taxing  authority.  Among its other duties, if required by the Code, the
REMIC  Provisions,  or other such guidance,  the Master Servicer shall provide
(i) to the Treasury or other  governmental  authority  such  information as is
necessary  for  the  application  of any tax  relating  to the  transfer  of a
Residual  Certificate to any  disqualified  person or organization and (ii) to
the Certificateholders such information or reports as are required by the Code
or REMIC Provisions.  

          (f) The Trustee, the Master Servicer and the Holders of Certificates
shall  take any  action  or cause the REMIC to take any  action  necessary  to
create  or  maintain  the  status  of such  REMIC as a REMIC  under  the REMIC
Provisions and shall assist each other as necessary to create or maintain such
status.  Neither  the  Trustee,  the  Master  Servicer  nor the  Holder of any
Residual Certificate shall take any action, cause the REMIC to take any action
or fail to take (or fail to cause to be  taken)  any  action  that,  under the
REMIC  Provisions,  if taken or not  taken,  as the  case  may be,  could  (i)
endanger the status of such REMIC as a REMIC or (ii) result in the  imposition
of a tax upon such REMIC  (including  but not limited to the tax on prohibited
transactions  as defined in Code Section  860F(a)(2) and the tax on prohibited
contributions set forth on Section 860G(d) of the Code) (either such event, an
"Adverse  REMIC  Event")  unless  the  Trustee  and the Master  Servicer  have
received an Opinion of Counsel  (at the  expense of the party  seeking to take
such action) to the effect that the contemplated action will not endanger such
status or result in the imposition of such a tax. In addition, prior to taking
any action with  respect to the REMIC or the assets  therein,  or causing such
REMIC to take any action,  which is not expressly permitted under the terms of
this  Agreement,  any Holder of a Residual  Certificate  will consult with the
Trustee and the Master Servicer,  or their respective  designees,  in writing,
with  respect to whether  such action  could  cause an Adverse  REMIC Event to
occur  with  respect to such  REMIC,  and no such  Person  shall take any such
action or cause such REMIC to take any such  action as to which the Trustee or
the Master  Servicer  has  advised it in writing  that an Adverse  REMIC Event
could occur. 

          (g) Each Holder of a Residual Certificate shall pay when due any and
all taxes  imposed  on the  related  REMIC by  federal  or state  governmental
authorities.  To the extent  that such Trust  taxes are not paid by a Residual
Certificateholder,  the  Trustee  shall pay any  remaining  REMIC taxes out of
current  or  future  amounts  otherwise  distributable  to the  Holder  of the
Residual  Certificate in such REMIC or, if no such amounts are available,  out
of other  amounts held in the  Collection  Account,  and shall reduce  amounts
otherwise  payable to holders of regular  interests in such REMIC, as the case
may be.  

          (h) The Master  Servicer  shall,  for federal  income tax  purposes,
maintain  books and records with respect to each REMIC on a calendar  year and
on an accrual basis.  

          (i) No  additional  contributions  of  assets  shall  be made to any
REMIC, except as expressly provided in this Agreement with respect to eligible
substitute  mortgage  loans.  

          (j) Neither the Trustee nor the Master Servicer shall enter into any
arrangement  by which any REMIC will receive a fee or other  compensation  for
services.  

          (k) On or before April 15 of each calendar  year  beginning in 1999,
the Master  Servicer  shall  deliver to the Trustee  and the Rating  Agency an
Officer's  Certificate  stating  the  Master  Servicer's  compliance  with the
provisions of this Section 10.01. 

          Section 10.02. Prohibited  Transactions and Activities.  Neither the
Depositor,  the Master  Servicer  nor the Trustee  shall sell,  dispose of, or
substitute for any of the Mortgage Loans, except in a disposition  pursuant to
(i) the foreclosure of a Mortgage Loan, (ii) the bankruptcy of the Trust Fund,
(iii) the termination of each REMIC pursuant to Article VII of this Agreement,
(iv)  a  substitution  pursuant  to  Article  II of  this  Agreement  or (v) a
repurchase of Mortgage  Loans  pursuant to Article II of this  Agreement,  nor
acquire any assets for any REMIC,  nor sell or dispose of any  investments  in
the Certificate  Account for gain, nor accept any  contributions  to the REMIC
after the Closing  Date,  unless it has received an Opinion of Counsel (at the
expense of the party causing such sale,  disposition,  or  substitution)  that
such disposition, acquisition, substitution, or acceptance will not (a) affect
adversely  the  status of such REMIC as a REMIC or of the  Certificates  other
than the Residual  Certificates as the regular interests  therein,  (b) affect
the distribution of interest or principal on the  Certificates,  (c) result in
the  encumbrance  of the  assets  transferred  or  assigned  to the Trust Fund
(except  pursuant to the provisions of this Agreement) or (d) cause such REMIC
to be subject to a tax on prohibited transactions or prohibited  contributions
pursuant to the REMIC Provisions.

          Section  10.03.  Indemnification  with Respect to Certain  Taxes and
Loss of REMIC  Status.  (a) In the event that the REMIC  fails to qualify as a
REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as
a result of a prohibited  transaction  or  prohibited  contribution  under the
REMIC  Provisions due to the negligent  performance by the Master  Servicer of
its  duties and  obligations  set forth  herein,  the  Master  Servicer  shall
indemnify the Holder of the Residual  Certificate  against any and all losses,
claims,  damages,  liabilities  or  expenses  ("Losses")  resulting  from such
negligence;  provided,  however,  that the Master Servicer shall not be liable
for any such Losses attributable to the action or inaction of the Trustee, the
Depositor, or the Holder of such Residual Certificate,  as applicable, nor for
any such Losses resulting from  misinformation  provided by the Holder of such
Residual  Certificate on which the Master  Servicer has relied.  The foregoing
shall not be deemed to limit or restrict the rights and remedies of the Holder
of such Residual  Certificate  now or hereafter  existing at law or in equity.
Notwithstanding the foregoing,  however, in no event shall the Master Servicer
have any  liability (1) for any action or omission that is taken in accordance
with and in  compliance  with the  express  terms  of,  or which is  expressly
permitted  by the terms of,  this  Agreement,  (2) for any  Losses  other than
arising out of a negligent  performance  by the Master  Servicer of its duties
and  obligations  set forth herein,  and (3) for any special or  consequential
damages  to  Certificateholders  (in  addition  to payment  of  principal  and
interest on the Certificates).

          Section 10.04. REO Property. (a) Notwithstanding any other provision
of this  Agreement,  the  Master  Servicer,  acting on  behalf of the  Trustee
hereunder,  shall not,  and shall,  to the extent  provided in the  applicable
Servicing  Agreement,  not permit any Servicer to, rent,  lease,  or otherwise
earn  income on behalf of any REMIC  with  respect to any REO  Property  which
might  cause such REO  Property to fail to qualify as  "foreclosure"  property
within the meaning of section  860G(a)(8) of the Code or result in the receipt
by any REMIC of any "income from  non-permitted  assets" within the meaning of
section  860F(a)(2) of the Code or any "net income from foreclosure  property"
which is subject to tax under the REMIC Provisions  unless the Master Servicer
has advised,  or has caused the applicable  Servicer to advise, the Trustee in
writing to the effect that, under the REMIC Provisions,  such action would not
adversely  affect the status of the REMIC as a REMIC and any income  generated
for such REMIC by the REO Property would not result in the imposition of a tax
upon such REMIC.

          (b) The Master  Servicer  shall  make,  or shall  cause the  Special
Servicer to make,  reasonable  efforts to sell any REO  Property  for its fair
market value. In any event, however, the Master Servicer shall, or shall cause
the Special  Servicer to, dispose of any REO Property  within three years from
the end of the calendar year of its  acquisition  by the Trust Fund unless the
Trustee has 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 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
Trustee  has  received  such an  extension,  then the  Trustee,  or the Master
Servicer,  acting on its behalf  hereunder,  shall, or shall cause the Special
Servicer to,  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 Trustee has not received such an extension and the
Trustee, or the Master Servicer acting on behalf of the Trustee hereunder,  or
the Special Servicer is unable to sell the REO Property within 33 months after
its  acquisition  by the Trust Fund or if the  Trustee  has  received  such an
extension,  and the Trustee,  or the Master  Servicer  acting on behalf of the
Trustee hereunder, is unable to sell the REO Property within the period ending
three months  before the close of the  Extended  Period,  the Master  Servicer
shall,  or shall cause the Special  Servicer  to,  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 Master
Servicer or the Special 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.

                                  ARTICLE XI

                           MISCELLANEOUS PROVISIONS

          Section  11.01.  Binding  Nature  of  Agreement;   Assignment.  This
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and permitted assigns.

          Section 11.02. Entire Agreement.  This Agreement contains the entire
agreement  and  understanding  among the parties  hereto  with  respect to the
subject   matter  hereof,   and  supersedes  all  prior  and   contemporaneous
agreements,  understandings,  inducements and conditions,  express or implied,
oral or written,  of any nature  whatsoever with respect to the subject matter
hereof.  The  express  terms  hereof  control  and  supersede  any  course  of
performance  and/or  usage of the  trade  inconsistent  with any of the  terms
hereof. 

          Section  11.03.  Amendment.  (a) This  Agreement may be amended from
time to time by the Depositor,  the Master  Servicer and the Trustee,  without
notice to or the  consent of any of the  Holders,  (i) to cure any  ambiguity,
(ii) to cause the provisions  herein to conform to or be consistent with or in
furtherance of the statements made with respect to the Certificates, the Trust
Fund or this Agreement in any Offering  Document;  or to correct or supplement
any  provision  herein  which may be  inconsistent  with any other  provisions
herein,  (iii) to make  any  other  provisions  with  respect  to  matters  or
questions  arising under this Agreement or (iv) to add,  delete,  or amend any
provisions   to  the  extent   necessary  or  desirable  to  comply  with  any
requirements  imposed by the Code and the REMIC Provisions.  No such amendment
effected pursuant to the preceding  sentence shall, as evidenced by an Opinion
of Counsel,  adversely affect the status of any REMIC created pursuant to this
Agreement,  nor shall such amendment effected pursuant to clause (iii) of such
sentence adversely affect in any material respect the interests of any Holder.
Prior to entering into any amendment  without the consent of Holders  pursuant
to this  paragraph,  the  Trustee  may  require an Opinion of Counsel  (at the
expense  of the party  requesting  such  amendment)  to the  effect  that such
amendment is  permitted  under this  paragraph.  Any such  amendment  shall be
deemed not to  adversely  affect in any  material  respect any Holder,  if the
Trustee  receives  written  confirmation  from each  Rating  Agency  that such
amendment  will not cause such Rating Agency to reduce the then current rating
assigned  to the  Certificates  (and any Opinion of Counsel  requested  by the
Trustee in  connection  with any such  amendment  may rely  expressly  on such
confirmation  as the basis  therefor).  

          (b) This  Agreement  may also be  amended  from  time to time by the
Depositor, the Master Servicer and the Trustee with the consent of the Holders
of not less  than  66-2/3%  of the  Class  Certificate  Principal  Amount  (or
Percentage  Interest) of each Class of Certificates  affected  thereby for the
purpose of adding any  provisions to or changing in any manner or  eliminating
any of the  provisions  of this  Agreement  or of  modifying in any manner the
rights of the Holders; provided, however, that no such amendment shall be made
unless the Trustee receives an Opinion of Counsel, at the expense of the party
requesting the change,  that such change will not adversely  affect the status
of the  REMIC as a REMIC  or  cause a tax to be  imposed  on such  REMIC;  and
provided  further,  that no such  amendment  may (i)  reduce in any manner the
amount of, or delay the timing of,  payments  received on Mortgage Loans which
are required to be distributed on any Certificate,  without the consent of the
Holder of such  Certificate or (ii) reduce the aforesaid  percentages of Class
Certificate  Principal Amount (or Percentage Interest) of Certificates of each
Class,  the  Holders of which are  required  to consent to any such  amendment
without the consent of the Holders of 100% of the Class Certificate  Principal
Amount (or Aggregate  Notional Amount) of each Class of Certificates  affected
thereby.  For purposes of this paragraph,  references to "Holder" or "Holders"
shall  be  deemed  to  include,  in  the  case  of  any  Class  of  Book-Entry
Certificates, the related Certificate Owners.

          (c) Promptly after the execution of any such amendment,  the Trustee
shall furnish written  notification of the substance of such amendment to each
Holder,  the  Depositor  and to the  Rating  Agencies.  

          (d) It shall not be necessary  for the consent of Holders under this
Section 11.03 to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent shall approve the substance  thereof.  The
manner of obtaining such consents and of evidencing the  authorization  of the
execution  thereof by Holders shall be subject to such reasonable  regulations
as the Trustee may prescribe.  

          (e)  Notwithstanding  anything  to the  contrary  in  any  Servicing
Agreement,  the Trustee  shall not consent to any  amendment of any  Servicing
Agreement  except  pursuant to the  standards  provided in this  Section  with
respect to amendment of this Agreement.  Section 1Voting Rights. Except to the
extent  that  the  consent  of all  affected  Certificateholders  is  required
pursuant to this  Agreement,  with respect to any provision of this  Agreement
requiring the consent of Certificateholders representing specified percentages
of aggregate  outstanding  Certificate  Principal Amount (or Notional Amount),
Certificates owned by the Depositor,  the Master Servicer,  the Trustee or any
Servicer  or  Affiliates  thereof  are  not to be  counted  so  long  as  such
Certificates are owned by the Depositor,  the Master Servicer,  the Trustee or
any Servicer or Affiliates thereof.

          Section 11.05.  Provision of Information.  (a) For so long as any of
the Certificates of any Series or Class are "restricted securities" within the
meaning of Rule 144(a)(3) under the Act, each of the Depositor and the Trustee
agree to cooperate with each other to provide to any Certificateholders and to
any    prospective    purchaser   of    Certificates    designated   by   such
Certificateholder,  upon the request of such  Certificateholder or prospective
purchaser,  any  information  required  to  be  provided  to  such  holder  or
prospective  purchaser to satisfy the condition  set forth in Rule  144A(d)(4)

in providing such  information  shall be reimbursed by the Depositor.  

          (b) The Trustee will provide to any person to whom a Prospectus  was
delivered,  upon  the  request  of such  person  specifying  the  document  or

          Agreement, exclusive of any experience in mortgage loan origination,
          and must be  reasonably  acceptable  to the Master  Servicer,  whose
          approval shall not be  unreasonably  withheld;  

                    (iii) Such successor  servicer must execute and deliver to

                    (v) The Seller shall,  at its cost and expense,  take such
          steps,  or cause the terminated  Servicer to take such steps, as may

          _______________________ (the "Transferor") has reviewed the attached
affidavit  of  _____________________________  (the  "Transferee"),  and has no
actual  knowledge that such affidavit is not true and has no reason to believe
that the information  contained in paragraph 7 thereof is not true, and has no
reason  to  believe  that the  Transferee  has the  intention  to  impede  the
assessment or collection of any federal, state or local taxes legally required
to be paid with respect to a Residual Certificate. In addition, the Transferor
has conducted a reasonable investigation at the time of the transfer and found
that the Transferee had historically paid its debts as they came due and found

                                                                     Date

Dear Sirs:

          In  connection  with  our  proposed   purchase  of   $______________
principal  amount of Mortgage  Pass-Through  Certificates,  Series 1998-6 (the
"Privately Offered  Certificates") of Structured Asset Securities  Corporation
(the "Depositor"), we confirm that:

(1)       We understand that the Privately Offered Certificates have not been,
          and will not be,  registered  under the  Securities  Act of 1933, as
          amended  (the  "Securities  Act"),  and may not be  sold  except  as
          permitted in the following sentence. We agree, on our own behalf and
          on behalf of any  accounts  for which we are  acting as  hereinafter
          stated,  that if we should sell any Privately  Offered  Certificates
          within three years of the later of the date of original  issuance of
          the  Privately  Offered  Certificates  or the last day on which such
          Privately  Offered  Certificates  are owned by the  Depositor or any
          affiliate of the Depositor  (which includes the Placement  Agent) we
          will  do  so  only  (A)  to  the   Depositor,   (B)  to   "qualified
          institutional  buyers"  (within  the  meaning of Rule 144A under the
          Securities  Act) in accordance  with Rule 144A under the  Securities
          Act  ("QIBs"),  (C) pursuant to an exemption  from  registration  in
          accordance  with Rule 904 of Regulation S under the Securities  Act,
          (D) pursuant to the exemption from registration provided by Rule 144
          under the  Securities  Act, or (E) to an  institutional  "accredited
          investor"  within the meaning of Rule 501(a)(1),  (2), (3) or (7) of
          Regulation  D  under  the  Securities  Act  that  is  not a QIB  (an
          "Institutional  Accredited Investor") which, prior to such transfer,
          delivers to the Trustee under the Trust  Agreement  dated as of June
          1, 1998  among  the  Depositor,  Norwest  Bank  Minnesota,  National
          Association,  as Master  Servicer and First Union  National Bank, as
          Trustee (the "Trustee"), a signed letter in the form of this letter;
          and we further agree, in the capacities  stated above, to provide to
          any person purchasing any of the Privately Offered Certificates from
          us a notice  advising such  purchaser  that resales of the Privately
          Offered Certificates are restricted as stated herein.

(2)       We understand  that, in connection  with any proposed  resale of any
          Privately  Offered  Certificates  to  an  Institutional   Accredited
          Investor,  we will be  required  to furnish to the  Trustee  and the
          Depositor a certification from such transferee in the form hereof to
          confirm  that  the  proposed  sale  is  being  made  pursuant  to an
          exemption from, or in a transaction not subject to, the registration
          requirements of the Securities  Act. We further  understand that the
          Privately Offered Certificates purchased by us will bear a legend to
          the foregoing effect.

(3)       We are acquiring the Privately  Offered  Certificates for investment
          purposes and not with a view to, or for offer or sale in  connection
          with, any  distribution  in violation of the Securities Act. We have
          such knowledge and  experience in financial and business  matters as
          to be capable of evaluating  the merits and risks of our  investment
          in the Privately  Offered  Certificates,  and we and any account for
          which we are acting are each able to bear the economic  risk of such
          investment.

(4)       We are an Institutional Accredited Investor and we are acquiring the
          Privately Offered  Certificates  purchased by us for our own account
          or for one or more  accounts  (each  of  which  is an  Institutional
          Accredited Investor) as to each of which we exercise sole investment
          discretion.

(5)       We have received such  information  as we deem necessary in order to
          make our investment decision.

(6)       If we are  acquiring  ERISA-Restricted  Certificates,  we understand
          that in accordance with ERISA,  the Code and the Exemption,  no Plan
          as to which the  Purchaser,  the  Depositor,  any Servicer or Master
          Servicer  or the  Trustee  is a party in  interest  or  disqualified
          person,  and no person  acting on behalf of such a Plan may  acquire
          such Certificate  unless the acquisition  would constitute an exempt
          transaction under a statutory exemption or any of the administrative
          exemptions issued by the U.S. Department of Labor.

          Terms used in this letter  which are not  otherwise  defined  herein
have the respective meanings assigned thereto in the Trust Agreement.

          You and the  Depositor are entitled to rely upon this letter and are
irrevocably  authorized  to  produce  this  letter  or a  copy  hereof  to any
interested party in any administrative or legal proceeding or official inquiry
with respect to the matters covered hereby.

                                                     Very truly yours,

     and in good standing under the laws governing its creation and existence
     and has full corporate power and authority to own its property, to carry
     on its business as presently conducted, and to enter into and perform its
     obligations under this Agreement;

          (ii) the execution and delivery by Lehman Capital of this Agreement
     have been duly authorized by all necessary corporate action on the part of
     Lehman Capital; neither the execution and delivery of this Agreement, nor
     the consummation of the transactions herein contemplated, nor compliance
     with the provisions hereof, will conflict with or result in a breach of,
     or constitute a default under, any of the provisions of any law,
     governmental rule, regulation, judgment, decree or order binding on Lehman
     Capital or its properties or the certificate of incorporation or bylaws of
     Lehman Capital; 

          (iii) the execution, delivery and performance by Lehman Capital of
     this Agreement and the consummation of the transactions contemplated
     hereby do not require the consent or approval of, the giving of notice to,
     the registration with, or the taking of any other action in respect of,
     any state, federal or other governmental authority or agency, except such
     as has been obtained, given, effected or taken prior to the date hereof;

          (iv) this Agreement has been duly executed and delivered by Lehman
     Capital and, assuming due authorization, execution and delivery by the
     Depositor, constitutes a valid and binding obligation of Lehman Capital
     enforceable against it in accordance with its terms except as such
     enforceability may be subject to (A) applicable bankruptcy and insolvency
     laws and other similar laws affecting the enforcement of the rights of
     creditors generally and (B) general principles of equity regardless of
     whether such enforcement is considered in a proceeding in equity or at
     law; and 

          (v) there are no actions, suits or proceedings pending or, to the
     knowledge of Lehman Capital, threatened or likely to be asserted against
     or affecting Lehman Capital, before or by any court, administrative
     agency, arbitrator or governmental body (A) with respect to any of the
     transactions contemplated by this Agreement or (B) with respect to any
     other matter which in the judgment of Lehman Capital will be determined
     adversely to Lehman Capital and will if determined adversely to Lehman
     Capital materially and adversely affect it or its business, assets,
     operations or condition, financial or otherwise, or adversely affect its
     ability to perform its obligations under this Agreement. 

     (b) The representations and warranties of each Transferor with respect to
the Mortgage Loans in the applicable Transfer Agreement were made as of the
date of such Transfer Agreement. To the extent that any fact, condition or
event with respect to a Mortgage Loan constitutes a breach of both (i) a
representation or warranty of a Transferor under the applicable Transfer
Agreement and (ii) a representation or warranty of Lehman Capital under this
Agreement, the only right or remedy of the Depositor shall be the right to
enforce the obligations of such Transferor under any applicable representation
or warranty made by it. The Depositor acknowledges and agrees that the
representations and warranties of Lehman Capital in this Section 1.04(b) are
applicable only to facts, conditions or events that do not constitute a breach
of any representation or warranty made by the related Transferor in the
applicable Transfer Agreement. Lehman Capital shall have no obligation or
liability with respect to any breach of a representation or warranty made by it
with respect to the Mortgage Loans if the fact, condition or event constituting
such breach also constitutes a breach of a representation or warranty made by
the related Transferor in such Transfer Agreement, without regard to whether
the related Transferor fulfills its contractual obligations in respect of such
representation or warranty. Subject to the foregoing, Lehman Capital represents
and warrants upon delivery of the Mortgage Loans to the Depositor hereunder, as
to each, that:

          (i) The information set forth with respect to the Mortgage Loans on
     the Mortgage Loan Schedule provides an accurate listing of the Mortgage
     Loans, and the information with respect to each Mortgage Loan on the
     Mortgage Loan Schedule is true and correct in all material respects at the
     date or dates respecting which such information is given;

          (ii) There are no defaults in complying with the terms of any
     Mortgage, and Lehman Capital has no notice as to any taxes, governmental
     assessments, insurance premiums, water, sewer and municipal charges,
     leasehold payments or ground rents which previously became due and owing
     but which have not been paid; 

          (iii) Except in the case of Cooperative Loans, each Mortgage requires
     all buildings or other improvements on the related Mortgaged Property to
     be insured by a generally acceptable insurer against loss by fire, hazards
     of extended coverage and such other hazards as are customary in the area
     where the related Mortgaged Property is located pursuant to insurance
     policies conforming to the requirements of the guidelines of FNMA or
     FHLMC. If upon origination of the Mortgage Loan, the Mortgaged Property
     was in an area identified in the Federal Register by the Federal Emergency
     Management Agency as having special flood hazards (and such flood
     insurance has been made available) a flood insurance policy meeting the
     requirements of the current guidelines of the Federal Flood Insurance
     Administration is in effect which policy conforms to the requirements of
     the current guidelines of the Federal Flood Insurance Administration. Each
     Mortgage obligates the related Mortgagor thereunder to maintain the hazard
     insurance policy at the Mortgagor's cost and expense, and on the
     Mortgagor's failure to do so, authorizes the holder of the Mortgage to
     obtain and maintain such insurance at such Mortgagor's cost and expense,
     and to seek reimbursement therefor from the Mortgagor. Where required by
     state law or regulation, each Mortgagor has been given an opportunity to
     choose the carrier of the required hazard insurance, provided the policy
     is not a "master" or "blanket" hazard insurance policy covering the common
     facilities of a planned unit development. The hazard insurance policy is
     the valid and binding obligation of the insurer, is in full force and
     effect, and will be in full force and effect and inure to the benefit of
     the Depositor upon the consummation of the transactions contemplated by
     this Agreement.

          (iv) Each Mortgage has not been satisfied, cancelled, subordinated or
     rescinded, in whole or in part, and the Mortgaged Property has not been
     released from the lien of the Mortgage, in whole or in part, nor has any
     instrument been executed that would effect any such release, cancellation,
     subordination or recision;

          (v) Each Mortgage evidences a valid, subsisting, enforceable and
     perfected first or second lien on the related Mortgaged Property
     (including all improvements on the Mortgaged Property). The lien of the
     Mortgage is subject only to: (1) liens of current real property taxes and
     assessments not yet due and payable and, if the related Mortgaged Property
     is a condominium unit, any lien for common charges permitted by statute,
     (2) covenants, conditions and restrictions, rights of way, easements and
     other matters of public record as of the date of recording of such
     Mortgage acceptable to mortgage lending institutions in the area in which
     the related Mortgaged Property is located and specifically referred to in
     the lender's Title Insurance Policy or attorney's opinion of title and
     abstract of title delivered to the originator of such Mortgage Loan, (3)
     such other matters to which like properties are commonly subject which do
     not, individually or in the aggregate, materially interfere with the
     benefits of the security intended to be provided by the Mortgage, and (4)
     in the case of second liens, to the subsisting first lien. Any security
     agreement, chattel mortgage or equivalent document related to, and
     delivered to the Trustee in connection with, a Mortgage Loan establishes a
     valid, subsisting and enforceable first or second lien, as applicable, on
     the property described therein and the Depositor has full right to sell
     and assign the same to the Trustee;

          (vi) Immediately prior to the transfer and assignment of the Mortgage
     Loans to the Depositor, Lehman Capital was the sole owner of record and
     holder of each Mortgage Loan, and Lehman Capital had good and marketable
     title thereto, and has full right to transfer and sell each Mortgage Loan
     to the Depositor free and clear, except as described in paragraph (v)
     above, of any encumbrance, equity, participation interest, lien, pledge,
     charge, claim or security interest, and has full right and authority,
     subject to no interest or participation of, or agreement with, any other
     party, to sell and assign each Mortgage Loan pursuant to this Agreement;

          (vii) Each Mortgage Loan other than any Cooperative Loan is covered
     by either (i) an attorney's opinion of title and abstract of title the
     form and substance of which is generally acceptable to mortgage lending
     institutions originating mortgage loans in the locality where the related
     Mortgaged Property is located or (ii) an ALTA mortgagee Title Insurance
     Policy or other generally acceptable form of policy of insurance, issued
     by a title insurer qualified to do business in the jurisdiction where the
     Mortgaged Property is located, insuring the originator of the Mortgage
     Loan, and its successors and assigns, as to the first or second priority
     lien of the Mortgage in the original principal amount of the Mortgage Loan
     (subject only to the exceptions described in paragraph (v) above. If the
     Mortgaged Property is a condominium unit located in a state in which a
     title insurer will generally issue an endorsement, then the related Title
     Insurance Policy contains an endorsement insuring the validity of the
     creation of the condominium form of ownership with respect to the project
     in which such unit is located. With respect to any Title Insurance Policy,
     the originator is the sole insured of such mortgagee Title Insurance
     Policy, such mortgagee Title Insurance Policy is in full force and effect
     and will inure to the benefit of the Depositor upon the consummation of
     the transactions contemplated by this Agreement, no claims have been made
     under such mortgagee Title Insurance Policy and no prior holder of the
     related Mortgage, including Lehman Capital, has done, by act or omission,
     anything that would impair the coverage of such mortgagee Title Insurance
     Policy;

          (viii) To the best of Lehman Capital's knowledge, no foreclosure
     action is being threatened or commenced with respect to any Mortgage Loan.
     There is no proceeding pending for the total or partial condemnation of
     any Mortgaged Property (or, in the case of a Cooperative Loan, the related
     cooperative unit) and each such property is undamaged by waste, fire,
     earthquake or earth movement, windstorm, flood, tornado or other casualty,
     so as to have a material adverse effect on the value of the related
     Mortgaged Property as security for the related Mortgage Loan or the use
     for which the premises were intended; 

          (ix) There are no mechanics' or similar liens or claims which have
     been filed for work, labor or material (and no rights are outstanding that
     under the law could give rise to such liens) affecting the related
     Mortgaged Property which are or may be liens prior to, or equal or
     coordinate with, the lien of the related Mortgage; 

          (x) Each Mortgage Loan was originated by a savings and loan
     association, savings bank, commercial bank, credit union, insurance
     company, or similar institution which is supervised and examined by a
     Federal or State authority, or by a mortgagee approved by the Secretary of
     Housing and Urban Development pursuant to sections 203 and 211 of the
     National Housing Act; and 

          (xi) Each Mortgage Loan is a "qualified mortgage" within the meaning
     of Section 860G of the Code and Treas. Reg. ss.1.860G-2. 

          It is understood and agreed that the representations and warranties
     set forth herein survive delivery of the Mortgage Files and the Assignment
     of Mortgage of each Mortgage Loan to the Depositor. Upon discovery by
     either Lehman Capital or the Depositor of a breach of any of the foregoing
     representations and warranties that adversely and materially affects the
     value of the related Mortgage Loan, and that does not also constitute a
     breach of a representation or warranty of the related Transferor in the
     applicable Transfer Agreement, the party discovering such breach shall
     give prompt written notice to the other party. Within 60 days of the
     discovery of any such breach, Lehman Capital shall either (a) cure such
     breach in all material respects, (b) repurchase such Mortgage Loan or any
     property acquired in respect thereof from the Depositor at the applicable
     Purchase Price or (c) within the two year period following the Closing
     Date, substitute a Qualifying Substitute Mortgage Loan for the affected
     Mortgage Loan.

     Section 1.05.  Grant Clause. It is intended that the conveyance of Lehman
Capital's right, title and interest in and to Mortgage Loans and other property
conveyed pursuant to this Agreement shall constitute, and shall be construed
as, a sale of such property and not a grant of a security interest to secure a
loan. However, if such conveyance is deemed to be in respect of a loan, it is
intended that: (1) the rights and obligations of the parties shall be
established pursuant to the terms of this Agreement; (2) Lehman Capital hereby
grants to the Depositor a first priority security interest in all of Lehman
Capital's right, title and interest in, to and under, whether now owned or
hereafter acquired, such Mortgage Loans and other property; and (3) this
Agreement shall constitute a security agreement under applicable law.

     Section 1.06.  Assignment by Depositor. The Depositor shall have the right,
upon notice to but without the consent of Lehman Capital, to assign, in whole
or in part, its interest under this Agreement with respect to the Mortgage
Loans to the Trustee, and the Trustee then shall succeed to all rights of the
Depositor under this Agreement. All references to the Depositor in this
Agreement shall be deemed to include its assignee or designee, specifically
including the Trustee.

                                  ARTICLE II.

                            MISCELLANEOUS PROVISIONS

     Section 2.01.  Binding Nature of Agreement; Assignment. This Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and permitted assigns.

     Section 2.02.  Entire Agreement. This Agreement contains the entire
agreement and understanding among the parties hereto with respect to the
subject matter hereof, and supersedes all prior and contemporaneous agreements,
understandings, inducements and conditions, express or implied, oral or
written, of any nature whatsoever with respect to the subject matter hereof.
The express terms hereof control and supersede any course of performance and/or
usage of the trade inconsistent with any of the terms hereof.

     Section 2.03.  Amendment. (a) This Agreement may be amended from time to
time by Lehman Capital and the Depositor, without notice to or the consent of
any of the Holders, (i) to cure any ambiguity, (ii) to cause the provisions
herein to conform to or be consistent with or in furtherance of the statements
made with respect to the Certificates, the Trust Fund, the Trust Agreement or
this Agreement in any Offering Document; or to correct or supplement any
provision herein which may be inconsistent with any other provisions herein,
(iii) to make any other provisions with respect to matters or questions arising
under this Agreement or (iv) to add, delete, or amend any provisions to the
extent necessary or desirable to comply with any requirements imposed by the
Code and the REMIC Provisions. No such amendment effected pursuant to clause
(iii) of the preceding sentence shall adversely affect in any material respect
the interests of any Holder. Any such amendment shall be deemed not to
adversely affect in any material respect any Holder, if the Trustee receives
written confirmation from each Rating Agency that such amendment will not cause
such Rating Agency to reduce the then current rating assigned to the
Certificates (and any Opinion of Counsel requested by the Trustee in connection
with any such amendment may rely expressly on such confirmation as the basis
therefor).

     (b) This Agreement may also be amended from time to time by Lehman Capital
and the Depositor with the consent of the Holders of not less than 66-2/3% of
the Class Certificate Principal Amount (or Percentage Interest) of each Class
of Certificates affected thereby for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Agreement
or of modifying in any manner the rights of the Holders; provided, however,
that no such amendment may (i) reduce in any manner the amount of, or delay the
timing of, payments received on Mortgage Loans which are required to be
distributed on any Certificate without, the consent of the Holder of such
Certificate or (ii) reduce the aforesaid percentages of Class Certificate
Principal Amount (or Percentage Interest) of Certificates of each Class, the
Holders of which are required to consent to any such amendment without the
consent of the Holders of 100% of the Class Certificate Principal Amount (or
Percentage Interest) of each Class of Certificates affected thereby. For
purposes of this paragraph, references to "Holder" or "Holders" shall be deemed
to include, in the case of any Class of Book-Entry Certificates, the related
Certificate Owners.

     (c) It shall not be necessary for the consent of Holders under this
Section 2.03 to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent shall approve the substance thereof. The
manner of obtaining such consents and of evidencing the authorization of the
execution thereof by Holders shall be subject to such reasonable regulations as
the Trustee may prescribe. 

     Section 2.04.  Governing Law. THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AND THE OBLIGATIONS, RIGHTS
AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH

partial exercise of any right, remedy, power or privilege preclude any other or
further exercise of the same or of any other right, remedy, power or privilege,
nor shall any waiver of any right, remedy, power or privilege with respect to
any occurrence be construed as a waiver of such right, remedy, power or
privilege with respect to any other occurrence. No waiver shall be effective
unless it is in writing and is signed by the party asserted to have granted
such waiver.

     Section 2.07.  Headings Not to Affect Interpretation.  The headings
contained in this Agreement are for convenience of reference only, and they
shall not be used in the interpretation hereof.

     Section 2.08. Benefits of Agreement. Nothing in this Agreement, express or
implied, shall give to any Person, other than the parties to this Agreement and
their successors hereunder, any benefit or any legal or equitable right, power,

  Draft No. 2

                          SPECIAL SERVICING AGREEMENT


     THIS SPECIAL SERVICING AGREEMENT (this "Agreement"), entered into as of
the 1st day of June, 1998, by and between LEHMAN CAPITAL, A DIVISION OF LEHMAN
BROTHERS HOLDINGS INC., a Delaware corporation ("Lehman Capital"), and OCWEN
FEDERAL BANK FSB, a federal savings bank (the "Special Servicer"):

                                    RECITALS

     WHEREAS, Lehman Capital has conveyed certain Mortgage Loans identified on
Schedule I hereto (the "Serviced Mortgage Loans") to Structured Asset
Securities Corporation ("SASCO"), which in turn has conveyed the Serviced
Mortgage Loans to First Union National Bank, as trustee (the "Trustee") under a
trust agreement dated as of June 1, 1998 (the "Trust Agreement"), among the
Trustee, Norwest Bank Minnesota, National Association, as master servicer
("Norwest," and, together with any successor Master Servicer appointed pursuant
to the provisions of the Trust Agreement, the "Master Servicer") and SASCO.

     WHEREAS, multiple classes of Certificates, including the Class B6
Certificates, will be issued on the Closing Date pursuant to the Trust
Agreement, and Lehman Pass-Through Securities Inc. or a nominee thereof
(together with any successor in interest thereto and any permitted assignee or
transferee thereof, the "Directing Holder") is expected to be the initial
registered Holder of the Class B6 Certificates.

     WHEREAS, Lehman Capital desires that the Special Servicer perform the
services with respect to the Serviced Mortgage Loans as provided in this
Agreement (including those provisions that are incorporated by reference
herein), and the Special Servicer has agreed to do so, subject to the
conditions set forth herein.

     WHEREAS, Norwest 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 Special Servicer
under this Special Servicing 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, Lehman Capital and the Special 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 Servicing Agreement dated
as of December 1, 1997, between Lehman Capital and the Special Servicer (the
"Servicing Agreement") incorporated by reference herein, shall have the
meanings ascribed to such terms in the Trust Agreement.

     2. Special Servicing. The Special 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 Servicing Agreement, except as otherwise provided herein and on Exhibit A
hereto, and that the provisions of the Servicing Agreement, as so modified, are
and shall be a part of this Agreement to the same extent as if set forth herein
in full.

     3. Master Servicing; Termination of Special Servicer. The Special
Servicer, including any successor special servicer hereunder, shall be subject
to the supervision of the Master Servicer, which Master Servicer shall be
obligated to ensure that the Special Servicer services the Serviced Mortgage
Loans in accordance with the provisions of this Agreement. The Master Servicer,
acting on behalf of the Trustee pursuant to the Trust Agreement, shall have the
same rights as the "Owner" (as defined in the Servicing Agreement) to enforce
the obligations of the Special Servicer under the Servicing Agreement. The
Master Servicer shall be entitled to terminate the rights and obligations of
the Special Servicer under this Agreement upon the failure of the Special
Servicer to perform any of its obligations under this Agreement, after the
expiration of any notice and cure periods, if any, as provided in Section 9.01
of the Servicing Agreement. If the Special Servicer is in default under this
Agreement, after the expiration of any notice and cure periods, if any, the
Master Servicer shall, upon the written direction of the Directing Holder,
terminate the rights and obligations of the Special Servicer under this
Agreement.

     Upon prior written notice, the Directing Holder shall have the exclusive
right to terminate the rights and obligations of the Special Servicer under
this Agreement without cause and without payment of any termination fee in
connection with such termination; provided, that (i) any successor special
servicer shall be appointed in the manner provided below and (ii) a letter is
provided to the Trustee from the Rating Agency to the effect that such
termination and appointment will not result in the qualification, reduction, or
withdrawal of the ratings applicable to the Certificates.

     Notwithstanding anything to the contrary in Sections 9.01, 9.02 and 10.01
of the Servicing Agreement, the Directing Holder shall, within 30 days of the
receipt by the Special Servicer of a copy of any termination notice delivered
by the Master Servicer to the Special Servicer or upon delivery by the
Directing Holder of any such notice pursuant Section 9.02 or upon receipt by
the Directing Holder of any resignation notice given by the Special Servicer,
notify the Master Servicer in writing of the Directing Holder's nominee as
successor special servicer, which nominee shall be appointed as special
servicer by the Master Servicer unless the Master Servicer reasonably objects
to such nominee within 10 days following receipt of such notice. If the Master
Servicer objects to such nominee, then the Master Servicer shall, within such
10-day period, appoint a successor special servicer, which successor shall be
reasonably acceptable to the Directing Holder.

     4. No Representations. Neither the Special Servicer nor the Master
Servicer shall be obligated or required to make any representations and
warranties regarding the Serviced Mortgage Loans in connection with the
transactions contemplated by the Trust Agreement and issuance of the
certificates issued pursuant thereto.

     5. Notices. All notices and communications between or among the parties
hereto shall be in writing and shall be deemed received or given when mailed
first-class mail, postage prepaid, addressed to each other party at its address
specified below. Each party may designate to the other parties in writing, from
time to time, other addresses to which notices and communications hereunder
shall be sent.

     6. Governing Law. THIS SPECIAL SERVICING AGREEMENT SHALL BE GOVERNED BY,
AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK,
NOTWITHSTANDING NEW YORK OR OTHER CHOICE OF LAW RULES TO THE CONTRARY.

     7. Counterparts. This Agreement may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original,
but all of which counterparts shall together constitute but one and the same
instrument.

     8. Reconstitution. Lehman Capital and the Special Servicer agree that this
Agreement is a Reconstitution Agreement, and that the date hereof is the
Reconstitution Date, each as defined in the Servicing Agreement. This Agreement
amends the terms and provisions of the Servicing Agreement only with respect to
the Serviced Mortgage Loans identified on Schedule I hereto and does not
purport to amend or modify the Servicing Agreement with respect to any other
loans that are or may become subject to the Servicing Agreement.

duties hereunder until the end of such preceding calendar year in the case of
the first such certificate) and that, on the basis of such examination
conducted substantially in compliance with the Uniform Single Attestation
Program for Mortgage Bankers, such firm is of the opinion that Special
Servicer's overall servicing operations have been conducted in compliance with
the Uniform Single Attestation Program for Mortgage Bankers except for such
exceptions that, in the opinion of such firm, the Uniform Single Attestation
Program for Mortgage Bankers requires it to report, in which case such
exceptions shall be set forth in such statement.

review, the Special Servicer has fulfilled all its obligations under this
Agreement for such year, or, if there has been a default in the fulfillment of
all such obligations, specifying each such default known to such officers and

     Special Servicer shall use its best reasonable efforts to determine
     whether any seller's representation or warranty applicable to such
     Mortgage Loan has been breached, and shall notify the Trustee and the
     Master Servicer in writing of any possible breach so identified. The
     Special Servicer may conclusively rely upon information provided by Lehman
     Capital, and its successors and assigns, including copies of any related
     agreements of sale, in determining which representations and warranties
     are applicable to such Mortgage Loan."

     No. ______, and various Mortgagors" in the first paragraph of Section 3.03

13.  Section 3.04(ii) is deleted in its entirety and replaced with the
     following:

          "(ii) to reimburse itself for unreimbursed advances of the Special
     Servicer's funds made pursuant to Section 2.05 hereof, including advances
     by the Special Servicer to reimburse the Primary Servicer for principal
     and interest advances, Servicing Advances and unpaid servicing fees due to
     them, if any, the Special Servicer's right to reimburse itself pursuant to
     this subclause (ii) being limited to either (x) amounts received on the
     related Transferred Mortgage Loan which represent late payments of
     principal and/or interest respecting which any such advance was made, and
     related Liquidation Proceeds, condemnation proceeds, Insurance Proceeds,
     REO Disposition Proceeds and other amounts received in respect of the
     related Mortgage Loan, it being understood that, in the case of any such
     reimbursement, the Special Servicer's right thereto shall be prior to the
     rights of the Owner, the Master Servicer, any Primary Servicer and any
     Certificateholder or (y) any other amounts in the Collection Account in
     the event that such advances have been deemed to be Nonrecoverable
     Advances or are not recovered from recoveries in respect of the related
     Transferred Mortgage Loan or REO Property after a final determination has
     been made as to what amounts have been or will be recovered, it being
     understood that for those Transferred Mortgage Loans in foreclosure, the
     Owner shall reimburse the Special Servicer for Servicing Advances and
     advances made pursuant to Section 2.05 hereof through the completion of
     the sale of the defaulted Mortgage Loan, or the foreclosure and
     disposition of the REO Property;"

14.  Section 3.04 is hereby amended by deleting clause (iii) in its entirety

          "(iii) to reimburse itself for Monthly Advances of the Special
     Servicer's funds made pursuant to Section 7.03, the Special Servicer's
     right to reimburse itself pursuant to this subclause (iii) being limited
     to amounts received on the related Mortgage Loan which represent late
     payments of principal and/or interest respecting which any such advance
     was made, related Liquidation Proceeds, Insurance Proceeds, condemnation
     proceeds, REO Disposition Proceeds and other amounts received in respect
     of the related REO Property, and such other amounts as may be collected by
     the Special Servicer from the Mortgagor or otherwise relating to such
     Mortgage Loan, it being understood that, in the case of any such
     reimbursement, the Special Servicer's right thereto shall be prior to the
     rights of the Owner, the Master Servicer, any Primary Servicer and any
     Certificateholder ; provided, that if the Special Servicer reasonably
     determines that any unreimbursed Monthly Advance is a Nonrecoverable
     Advance, the foregoing limitation shall not apply thereto;

          (iv) to reimburse itself for unreimbursed Servicing Advances, and for
     any unpaid Base Servicing Fees, the Special Servicer's right to reimburse
     itself pursuant to this subclause (iv) with respect to any Mortgage Loan

     condemnation proceeds, Insurance Proceeds, REO Disposition Proceeds and
     other amounts received in respect of the related REO Property, and such
     other amounts as may be collected by the Special Servicer from the
     Mortgagor or otherwise relating to the Mortgage Loan, it being understood
     that, in the case of any such reimbursement, the Special Servicer's right
     thereto shall be prior to the rights of the Owner; provided, that if the
     Special Servicer reasonably determines that any unreimbursed Servicing
     Advance is a Nonrecoverable Advance, the foregoing limitation shall not
     apply thereto;"

          Clauses (iv) through (viii) in Section 3.04 are hereby redesignated
     clauses (v) through (ix), as applicable.

15.  The words "Special Servicer, in trust for Lehman Capital, A Division of
     Lehman Brothers Holdings, Inc., owner of Residential Mortgage Loans, Group
     No. ______, and various Mortgagors" in the first paragraph of Section 3.05
     are hereby deleted and replaced with the following: "Ocwen Federal Bank
     FSB, in trust for Norwest Bank Minnesota, National Association, as master
     servicer for SASCO 1998-6."

16.  Section 3.10(a) is deleted in its entirety and replaced with the
     following:

          "(a) Default Management Responsibilities: Subject only to Accepted
     Servicing Practices and Section 3.11 below, the Special Servicer shall
     have full power and authority to do or cause to be done any and all things
     in connection with such servicing and administration which it may deem
     necessary or desirable. Without limiting the generality of the foregoing,
     the Special Servicer is hereby authorized and empowered by the Owner (if,
     in the Special Servicer's reasonable judgment, such action with respect to
     the Transferred Mortgage Loans and/or the Mortgaged Properties is in the
     best interests of Owner in accordance with, or is required by, this
     Agreement, and subject to Accepted Servicing Practices) to take the
     following actions (without limitation): (i) prepare, execute and deliver,
     on behalf of the Owner with expenses associated therewith being Servicing
     Advances hereunder, any and all financing statements, continuation
     statements and other documents or instruments necessary to maintain the
     lien on each Mortgaged Property and related collateral; and, subject to
     the remaining terms and provisions of this Section, modifications, waivers
     (including, without limitation, waivers of any late payment charge in
     connection with any delinquent payment on a Transferred Mortgage Loan),
     consents, amendments, discounted payoff agreements, forbearance
     agreements, cash management agreements or consents to or with respect to
     any documents contained in the related servicing file; and any and all
     instruments of satisfaction or cancellation, or of partial or full release
     or discharge, and all other instruments comparable to any of the types of
     instruments described in this subsection (i), and (ii) institute and
     prosecute judicial and non-judicial foreclosures, suits on promissory
     notes, indemnities, guaranties or other loan documents, actions for
     equitable and/or extraordinary relief (including, without limitation,
     actions for temporary restraining orders, injunctions, and appointment of
     receivers), suits for waste, fraud and any and all other tort, contractual
     and/or other claims of whatever nature, and to appear in and file on
     behalf of the Owner such pleadings or documents as may be necessary or
     advisable in any bankruptcy action, state or federal suit or any other
     action. In the event that any Mortgage Loan is in default or, in the
     judgment of the Special Servicer, such default is reasonably foreseeable,
     the Special Servicer, consistent with Accepted Servicing Practices, may
     waive, modify or vary any term of such Mortgage Loan (including
     modifications that would change the Mortgage Interest Rate, defer or
     forgive the payment of principal or interest or extend the final maturity
     date of such Mortgage Loan), accept payment from the related Mortgagor of
     an amount less than the full outstanding and unpaid principal balance in
     final satisfaction of such Mortgage or consent to the postponement of
     strict compliance with any such term or otherwise grant indulgence to any
     Mortgagor if in the Special Servicer's determination such waiver,
     modification, postponement or indulgence is not materially adverse to the
     interests of the Certificateholders (taking into account any estimated
     Realized Loss that might result absent such action). In addition, if, with
     respect to a Transferred Mortgage Loan, a default (or any condition
     resulting in a default being reasonably foreseeable) is cured (such
     Mortgage Loan being referred to herein as a "Performing Loan"), the
     Special Servicer may thereafter waiver, modify or vary terms of such
     Performing Loan provided that no such action will (A) decrease the
     Mortgage Rate on the Performing Loan, (B) defer or forgive the payment of
     principal or interest (except with respect to liquidation of such
     Performing Loan) or (C) extend the final maturity date of such Performing
     Loan, provided, however, that no such modification shall be permitted to
     the extent that it would (a) affect adversely the status of the Trust Fund
     as a REMIC or (b) cause the Trust Fund to be subject to a tax on
     "prohibited transactions" or "contributions" pursuant to the REMIC
     Provisions.

          Notwithstanding anything to the contrary in this Agreement, the
     Special Servicer shall not waive any premium or penalty in connection with
     a prepayment of principal of any Mortgage Loan, and shall not consent to
     the modification of any Mortgage Note to the extent that such modification
     relates to payment of a prepayment premium or penalty; provided, that the
     foregoing shall not (i) apply to any Severely Delinquent Loan or (ii)
     prohibit the Special Servicer from entering into any agreement for
     modification, waiver, forbearance, amendment or discounted payoff of a
     Mortgage Loan in accordance with this Agreement that does not have the
     effect of waiving any prepayment premium or penalty or modifying any
     provision requiring payment thereof.

          Notwithstanding the foregoing, in the event of any conflict between
     the provisions of this Section 3.10 and the provisions of Section 3.11,
     the provisions of Section 3.11 shall control."

17.  Section 3.10(e) is hereby deleted in its entirety and replaced with the
     following:

          "(e) At any time, the Directing Holder may request that the Special
     Servicer take a particular action with respect to a particular Mortgage
     Loan, including without limitation foreclosure, waivers or modifications.
     Any such request shall be in writing, a copy of which shall be delivered
     to the Master Servicer. If the Special Servicer determines that such
     requested action is consistent with Accepted Servicing Practices, then the
     Special Servicer shall comply with such request. Within two Business Days
     of receipt of such a request, the Special Servicer shall notify the
     Directing Holder whether the Special Servicer intends to comply with such
     request. If the Special Servicer does not comply with such request (or
     fails to notify the Directing Holder of its decision within the two
     Business Day period), then the Directing Holder may, at its sole option
     and upon written notice to the Special Servicer and the Master Servicer,
     purchase the related Mortgage Loan from the Trust Fund at the Purchase
     Price (as defined in the Trust Agreement). In addition, the Directing
     Holder may purchase any Severely Delinquent Mortgage Loan upon written
     notice to the Master Servicer and the Special Servicer within three
     Business Days of the day on which such Mortgage Loan becomes a Severely
     Delinquent Loan.

          The Special Servicer shall have the right to purchase any Severely
     Delinquent Loan at the Purchase Price (as defined in the Trust Agreement).
     The Special Servicer shall send a written notice (the "Initial Notice") to
     the Directing Holder advising the Directing Holder that the Special
     Servicer intends to purchase a Severely Delinquent Loan. The Directing
     Holder shall have the option to (i) direct the Special Servicer not to
     purchase any such Severely Delinquent Loan but to proceed with a
     particular default resolution strategy consistent with Accepted Servicing
     Practices, (ii) direct the Special Servicer to proceed with the purchase
     of such loan on the terms proposed by the Special Servicer, or (iii)
     indicate that the Directing Holder intends to purchase such Severely
     Delinquent Loan, in which case the Directing Holder shall have the sole
     right and option to purchase the Severely Delinquent Loan at the Purchase
     Price; provided, however, that if the Directing Holder fails or refuses to
     deliver a written notice of its election to the Special Servicer within
     two Business Days after the Special Servicer has sent to the Directing
     Holder the Initial Notice, then the Directing Holder shall be deemed to
     have consented to the Special Servicer purchasing the Severely Delinquent
     Loan for its own account."

18.  The following Section 3.11 is hereby added immediately following Section
     3.10:

          "Section 3.11 REMIC Provisions.

          (a) Unless the Mortgagor is in default with respect to the related
     Mortgage Loan or such default is, in the judgment of the Special Servicer,
     reasonably foreseeable, the Special Servicer shall not permit any
     modification of any material term of any Mortgage Loan, including any
     modification that would change the Mortgage Interest Rate, defer or
     forgive the payment of principal or interest, reduce or increase the
     outstanding principal balance (except for actual payments of principal),
     change the final maturity date on such Mortgage Loan, or permit any
     alteration, substitution or release of any collateral for such Mortgage
     Loan.

          (b) The Special Servicer shall dispose of any 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 (i) the Owner
     shall have been supplied with an Opinion of Counsel to the effect that the
     holding by the Trust Fund of such Mortgaged Property subsequent to such
     three-year period (and specifying the period beyond such three-year period
     for which the Mortgaged Property may be held) will not result in the
     imposition of taxes on "prohibited transactions" of the Trust Fund as
     defined in section 860F of the Code, or cause the related REMIC to fail to
     qualify as a REMIC, in which case the Trust Fund may continue to hold such
     Mortgaged Property (subject to any conditions contained in such Opinion of
     Counsel), or (ii) the Owner (at the Special Servicer's expense) or the
     Special Servicer shall have applied for, not later than 61 days prior to
     the expiration of such three-year period, an extension of such three-year
     period in the manner contemplated by section 856(e)(3) of the Code, in
     which case the three-year period shall be extended by the applicable
     period. If a period longer than three years is permitted under the
     foregoing sentence and is necessary to sell any REO Property, (i) the
     Special Servicer shall report monthly to the Owner as to the progress
     being made in selling such REO Property and (ii) if, with the written
     consent of the Owner, a purchase money mortgage is taken in connection
     with such sale, such purchase money mortgage shall name the Special
     Servicer as mortgagee, and such purchase money mortgage shall not be held
     pursuant to this Agreement, but instead a separate participation agreement
     between the Special Servicer and the Owner shall be entered into with
     respect to such purchase money mortgage.

          Notwithstanding any other provision of this Agreement, no Mortgaged
     Property held by a REMIC shall be rented (or allowed to continue to be
     rented) or otherwise used for the production of income by or on behalf of
     the Trust Fund or sold in such a manner or pursuant to any terms that
     would (i) cause such Mortgaged Property to fail to qualify at any time as
     "foreclosure property" within the meaning of section 860G(a)(8) of the
     Code, (ii) subject the Trust Fund to the imposition of any federal or
     state income taxes on "net income from foreclosure property" with respect
     to such Mortgaged Property within the meaning of section 860G(c) of the
     Code, or (iii) cause the sale of such Mortgaged Property to result in the
     receipt by the Trust Fund of any income from non-permitted assets as
     described in section 860F(a)(2)(B) of the Code, unless the Special
     Servicer has agreed to indemnify and hold harmless the Trust Fund with
     respect to the imposition of any such taxes."

19.  The first paragraph of Section 4.01 is hereby deleted and replaced with
     the following:

          "On each Remittance Date the Servicer shall remit by wire transfer of
     immediately available funds to the Master Servicer (a) all amounts
     deposited in the Custodial Account as of the close of business on the last
     day of the related Due Period (net of charges against or withdrawals from
     the Custodial Account pursuant to Section 3.04), plus (b) all amounts, if
     any, which the Servicer is obligated to advance pursuant to Section 7.03,
     minus (c) any amounts attributable to Principal Prepayments, Liquidation
     Proceeds, Insurance Proceeds or REO Disposition Proceeds received after
     the applicable Prepayment Period, which amounts shall be remitted on the
     following Remittance Date, together with any additional interest required
     to be deposited in the Custodial Account in connection with such Principal
     Prepayment in accordance with Section 7.03, and minus (d) any amounts
     attributable to Monthly Payments collected but due on a due date or dates
     subsequent to the first day of the month in which such Remittance Date
     occurs, which amounts shall be remitted on the Remittance Date next
     succeeding the Due Period for such amounts."

20.  Section 4.02 is hereby amended by deleting the words "Remittance Date" in
     the first line of such Section, and substituting the following: "tenth day

basis to Structured Asset Securities  Corporation  ("SASCO"),  which in turn has
conveyed the Serviced  Mortgage  Loans to First Union  National Bank, as trustee

appointed  pursuant  to the  provisions  of the  Trust  Agreement,  the  "Master
Servicer") and SASCO.

         WHEREAS,  Lehman Capital  continues to own the servicing  rights to the
Serviced  Mortgage Loans,  and may freely  transfer such rights,  subject to the
terms hereof.

         WHEREAS,  Lehman Capital desires that the Servicer service the Serviced
Mortgage  Loans,  and the Servicer has agreed to do so,  subject to the right of
Lehman Capital to terminate the rights and obligations of the Servicer hereunder
at any time and to the other conditions set forth herein.

         WHEREAS,  Norwest 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

         NOW, THEREFORE,  in consideration of the mutual agreements  hereinafter
set  forth  and for other  good and  valuable  consideration,  the  receipt  and

Agreement,  including  Exhibit A hereto and any provisions of the Flow Servicing

Servicing  Fee or any  portion  thereof,  or,  except  as  provided  in the Flow
Servicing  Agreement,  to any other amounts in respect of the Serviced  Mortgage
Loans.

rights relating to the Serviced  Mortgaged Loans, and the Servicer shall have no
right to transfer the servicing thereof.

obligations  under this  Agreement.  Such  fidelity  bond and policy pr policies

provision if an affiliate  of the  Servicer  has such errors and  omissions  and

bond, the coverage  afforded  thereunder  extends to the Servicer.  The Servicer

statement to Owner,  Directing  Holder and Master  Servicer,  to the effect that
such firm has examined  certain  documents and records for the preceding  fiscal
year (or during  the period  from the date of  commencement  of such  servicer's
duties  hereunder until the end of such preceding fiscal year in the case of the
first such  certificate)  and that, on the basis of such  examination  conducted
substantially  in compliance  with the Uniform  Single  Attestation  Program for
Mortgage Bankers,  such firm is of the opinion that Servicer's overall servicing
operations have been conducted in compliance with the Uniform Single Attestation
Program for Mortgage  Bankers except for such exceptions that, in the opinion of
such firm, the Uniform Single Attestation  Program for Mortgage Bankers requires
it to  report,  in  which  case  such  exceptions  shall  be set  forth  in such
statement.

         12. Annual Officer's  Certificate.  On or before April 30 of each year,
beginning with April 30, 1999, the Servicer, at its own expense, will deliver to

         collected in the ordinary course of servicing the Mortgage  Loans.  The
         Servicer  shall not make any future  advances to any obligor  under any
         Mortgage  Loan, and (unless the Mortgagor is in default with respect to
         the Mortgage  Loan or such default is, in the judgment of the Servicer,
         reasonably  foreseeable) the Servicer shall not permit any modification
         of any material term of any Mortgage Loan,  including any  modification
         that would  change the  Mortgage  Interest  Rate,  defer or forgive the

         payments on any Mortgage Loan, the Servicer  shall, on the Business Day
         immediately  preceding  the  Remittance  Date in any month in which any
         such principal or interest  payment has been  deferred,  make a Monthly
         Advance in  accordance  with  Section  4.03,  in an amount equal to the

         Loan and (b) the amount paid by the  Mortgagor.  The Servicer  shall be
         entitled to  reimbursement  for such advances to the same extent as for
         all other advances made pursuant to Section 4.03.  Without limiting the

         a prepayment of principal of any Mortgage  Loan,  and shall not consent

                  "On each  Remittance  Date the  Servicer  shall  remit by wire
         transfer of immediately  available funds to the Master Servicer (a) all
         amounts  deposited in the Custodial Account as of the close of business
         on the last day of the related  Due Period  (net of charges  against or
         withdrawals from the Custodial  Account pursuant to Section 3.04), plus
         (b) all amounts,  if any, which the Servicer is obligated to distribute
         pursuant  to  Section  7.03,  minus  (c) any  amounts  attributable  to
         Principal  Prepayments,   Liquidation  Proceeds,   Insurance  Proceeds,
         Condemnation  Proceeds or REO Disposition  Proceeds  received after the
         applicable  Prepayment  Period,  which amounts shall be remitted on the
         following  Remittance  Date,  together  with  any  additional  interest
         required to be deposited in the Custodial  Account in  connection  with
         such  Principal  Prepayment in accordance  with Section 7.03, and minus
         (d) any amounts attributable to Monthly Payments collected but due on a
         due date or dates  subsequent  to the  first  day of the month in which
         such  Remittance  Date occurs,  which  amounts shall be remitted on the
         Remittance Date next succeeding the Due Period for such amounts."

         in the first line of such  Section,  and  substituting  the  following:
         "tenth Business Day of each month"

17. The third paragraph of Section 5.01 is hereby deleted.

18. The following paragraph is hereby added at the end of Section 9.02:

                  "On the second Business Day of each month,  the Servicer shall
         orally inform the Master Servicer and the Special  Servicer as to which
         Mortgage Loans have become  delinquent for a period of 61 days or more,
         without  giving  effect to any grace  period  permitted  by the related
         Mortgage Note (each, a "Distressed  Mortgage  Loan").  No Mortgage Loan
         shall be considered to be delinquent  for such purpose by virtue of the
         related  Mortgagor  having made payment to a prior  servicer.  Any such
         Mortgage  Loan as to which all past due  payments are made prior to the
         Notice Date shall not be considered to be a Distressed  Mortgage  Loan,
         and the servicing  thereof shall not be transferred as provided  below.
         On the  fourth  Business  Day of each month (the  "Notice  Date"),  the
         Servicer  shall send by facsimile a written  listing of the  Distressed
         Mortgage Loans to the Master  Servicer,  the Trustee and the Custodian,
         and shall  mail to the  Mortgagor  of each  Mortgage  Loan  listed in a
         Transfer  Notice a letter  advising each such Mortgagor of the transfer
         of the servicing of the related Mortgage Loan to the Special  Servicer,
         in accordance with the Cranston  Gonzales National  Affordable  Housing
         Act of 1990;  provided,  however, the content and format of such letter
         shall have the prior  approval of the Special  Servicer.  The  Servicer
         shall  promptly  provide the Special  Servicer  with copies of all such
         notices.  The transfer of servicing  with respect to each such Mortgage
         Loan to the Special  Servicer  shall be effected  by the  Servicer  not
         later than  fifteenth  day following  the  applicable  Notice Date (the
         "Transfer Date"). By the Business Day immediately following each Notice
         Date,  the  Servicer  shall  provide the Master  Servicer,  the Special
         Servicer,  the  Trustee and the  Custodian  with a  certification  (the
         "Transfer Notice") listing the Distressed Mortgage Loans.

                  At least five  Business Days prior to the Transfer  Date,  the
         Servicer shall deliver,  with respect to the Distressed  Mortgage Loans
         listed on the related  Transfer  Notice,  to the Special  Servicer  all
         Servicing  Files, and to the Special Servicer and the Master Servicer a
         preliminary  loan level tape or other  electronic media (a "Report") in
         form reasonably acceptable to the Servicer, the Master Servicer and the
         Special  Servicer.  Within two Business  Days  following  such Transfer
         Date, the Servicer  shall deliver such Report in final form  reasonably
         acceptable  to the  Master  Servicer  and  the  Special  Servicer,  and
         commensurate with generally  acceptable industry  standards,  detailing
         the amount of any unreimbursed Monthly Advances, Servicing Advances and
         accrued and unpaid  Servicing  Fees on a loan level  basis.  Should the
         Master  Servicer  or the Special  Servicer  desire a loan level tape or
         other  electronic  media  containing  information  which is not readily
         extractable from the Servicer's  servicing  system,  the Servicer shall
         diligently  cooperate  to make such loan  level data  available  to the
         Master  Servicer  and  Special  Servicer.  In  addition,  at least five
         Business Days prior to the Transfer  Date,  the Servicer shall transfer
         to the  Special  Servicer  any  funds  held  in an  Escrow  Account  or
         Custodial  Account relating to the Distressed  Mortgage Loans listed in
         the related  Transfer  Notice.  Upon the  successful  completion of the
         transfer  of  servicing  for  Distressed  Mortgage  Loans,  the Special
         Servicer  will  reimburse  the  Servicer for any  unreimbursed  Monthly
         Advances, Servicing Advances and accrued and unpaid Servicing Fees with
         respect to such  Distressed  Mortgage  Loans  which have been  properly
         documented.  The Servicer shall be paid, from the Custodial  Account, a
         termination fee of $25.00 for each Distressed Mortgage Loan transferred
         to the Special Servicer.

                  In  connection  with the transfer of any  Distressed  Mortgage
         Loan, (i) the Servicer will be responsible for servicing the Distressed
         Mortgage Loan until the effective  date of transfer of servicing to the
         Special Servicer, but shall have no right or obligation to service such
         Distressed  Mortgage  Loan  from and after  the  effective  date of the
         transfer of servicing  to the Special  Servicer,  (ii)  notwithstanding
         clause (i) above,  the Servicer shall include the  Distressed  Mortgage
         Loan in its monthly  remittance report pursuant to Section 4.02 for the
         month in which  such  transfer  is  effected  and  shall be  obligated,
         subject to Section  7.03,  to make the Monthly  Advance with respect to
         such  Distressed  Mortgage Loan on the Remittance  Date in the month in
         which such  transfer is effected,  in each case,  regardless of whether
         the  Remittance  Date occurs before or after the effective date of such
         transfer,  (iii) the amount of Monthly Advances to be reimbursed to the
         Servicer by the Special  Servicer  hereunder  shall include the Monthly
         Advance  described  in clause  (ii) above  regardless  of  whether  the
         Servicer makes such Monthly  Advance before or after the effective date
         of such transfer, (iv) the Servicer shall, no later than the end of the
         month in which  such  transfer  is  effected,  provide  to the  Special
         Servicer  loan  level  information  (in the  loan  level  tape or other
         electronic  media or other  agreed-upon  form) regarding the Distressed
         Mortgage  Loan during the month of such transfer as may be necessary to
         enable  the  Special  Servicer  to  provide  such  information  in  its
         remittance  report for the next following  month,  and (v) the Servicer
         shall not be  entitled  to the  Servicing  Fee with  regard to any such
         Distressed Mortgage Loan for the month in which such transfer occurs."
19. The following paragraph is added at the end of Section 10.01:

                  "Neither  the  Master  Servicer  nor  any  successor  servicer
         (including the Owner and the Master  Servicer)  shall be liable for any
         acts or  omissions  of the  Servicer or any  predecessor  servicer.  In
         particular,  neither the Master  Servicer  nor any  successor  servicer
         (including the Owner and the Master  Servicer)  shall be liable for any
         servicing  errors or  interruptions  resulting  from any failure of the
         Servicer to maintain  computer and other  information  systems that are
         year-2000 compliant."

20. The following words are hereby added after the words "Attention: Rick Skogg"

         required to be deposited in the Custodial  Account in  connection  with
         such  Principal  Prepayment in accordance  with Section 7.04, and minus
         (d) any amounts  attributable  to Monthly  Payments  collected  but due
         (giving  effect to Section  5.03) on a due date or dates  subsequent to
         the first day of the month in which such Remittance Date occurs,  which
         amounts shall be remitted on the  Remittance  Date next  succeeding the
         Due Period for such amounts."

14.      Section 5.02 is hereby amended by deleting the words  "Remittance Date"
         in the first line of such  Section,  and  substituting  the  following:
         "tenth day of each month,  or if such tenth day is not a Business  Day,
         the immediately preceding Business Day,"

15.      Section 5.03 is hereby deleted in its entirety.

16.      Section  6.03 is hereby  amended  by adding the  following  immediately
         after the words "other  ancillary fees" in the second paragraph of such
         Section:  ", but not including any premium or penalty associated with a
         prepayment of principal of a Mortgage Loan."

17.       The second  paragraph  of Section  11.02 is hereby  deleted in its
          entirely and replaced with the following:

                  "On the second  Business Day of each month,  the Company shall
         orally inform the Master Servicer and the Special  Servicer as to which
         Mortgage Loans have become  delinquent for a period of 61 days or more,
         without  giving  effect to any grace  period  permitted  by the related
         Mortgage Note (each, a "Distressed  Mortgage Loan").  Any such Mortgage
         Loan as to which all past due  payments  are made  prior to the  Notice
         Date shall not be considered to be a Distressed  Mortgage Loan, and the
         servicing  thereof shall not be transferred as provided  below.  On the
         fourth  Business  Day of each month (the  "Notice  Date"),  the Company
         shall send by facsimile a written  listing of the  Distressed  Mortgage
         Loans to the Master Servicer, the Trustee and the Custodian,  and shall
         mail to the Mortgagor of each Mortgage Loan listed in a Transfer Notice
         a letter  advising each such Mortgagor of the transfer of the servicing
         of the related  Mortgage  Loan to the Special  Servicer,  in accordance
         with the Cranston  Gonzales  National  Affordable  Housing Act of 1990;
         provided, however, the content and format of such letter shall have the
         prior  approval of the Special  Servicer.  The Company  shall  promptly
         provide  the Special  Servicer  with  copies of all such  notices.  The
         transfer of servicing  with respect to each such  Mortgage  Loan to the
         Special  Servicer  shall be  effected by the Company not later than the
         fifteenth  day  following  the  applicable  Notice Date (the  "Transfer
         Date"). By the Business Day immediately following each Notice Date, the
         Company shall provide the Master Servicer,  the Special  Servicer,  the
         Trustee and the Custodian with a certification  (the "Transfer Notice")
         listing the Distressed Mortgage Loans.

                  At least five Business Days prior to each Transfer  Date,  the
         Company shall deliver,  with respect to the  Distressed  Mortgage Loans
         listed on the related  Transfer  Notice,  to the Special  Servicer  all
         Servicing  Files, and to the Special Servicer and the Master Servicer a
         loan  level  tape or other  electronic  media  containing  loan  set-up
         information in form  reasonably  acceptable to the Master  Servicer and
         the Special Servicer.  Within two Business Days following such Transfer
         Date,  the Servicer  shall  deliver a final trial  balance  (subject to
         special claims),  in form reasonably  acceptable to the Master Servicer
         and the Special Servicer,  and commensurate  with generally  acceptable
         industry  standards,  detailing the amount of any unreimbursed  Monthly
         Advances, Servicing Advances and accrued and unpaid Servicing Fees on a
         loan level basis.  Should the Master  Servicer or the Special  Servicer
         desire  a  loan  level  tape  or  other   electronic  media  containing
         information  which  is  not  readily  extractable  from  the  Company's
         servicing system,  the Company shall reasonably  cooperate to make such
         loan level data available to the Master Servicer and Special  Servicer.
         In addition,  no more than two Business  Days after the Transfer  Date,
         the Company shall transfer to the Special Servicer any funds held in an
         Escrow Account or Custodial Account relating to the Distressed Mortgage
         Loans listed in the related Transfer Notice. Upon reasonable compliance
         by the  Company  with the  provisions  of this  Section  regarding  the
         transfer  of  servicing  for  Distressed  Mortgage  Loans,  the Special
         Servicer will  reimburse the Company  within five Business Days for any
         unreimbursed  Monthly  Advances,  Servicing  Advances  and  accrued and
         unpaid  Servicing Fees with respect to such  Distressed  Mortgage Loans
         which have been properly documented. Notwithstanding anything herein to
         the contrary,  the transfer of servicing for Distressed  Mortgage Loans
         shall not require the payment of a termination fee therefor.

                  In  connection  with the transfer of any  Distressed  Mortgage
         Loan, (i) the Company will be responsible  for servicing the Distressed
         Mortgage Loan until the effective  date of transfer of servicing to the
         Special Servicer, but shall have no right or obligation to service such
         Distressed  Mortgage  Loan  from and after  the  effective  date of the
         transfer of servicing  to the Special  Servicer,  (ii)  notwithstanding
         clause (i) above,  the Company  shall include the  Distressed  Mortgage
         Loan in its monthly  remittance report pursuant to Section 5.02 for the
         month in which  such  transfer  is  effected  and  shall be  obligated,
         subject to Section  7.03,  to make the Monthly  Advance with respect to
         such  Distressed  Mortgage Loan on the Remittance  Date in the month in
         which such  transfer is effected,  in each case,  regardless of whether
         the  Remittance  Date occurs before or after the effective date of such
         transfer,  (iii) the amount of Monthly Advances to be reimbursed to the
         Company by the Special  Servicer  hereunder  shall  include the Monthly
         Advance  described  in clause  (ii) above  regardless  of  whether  the
         Company makes such Monthly  Advance  before or after the effective date
         of such transfer,  (iv) the Company shall, no later than the end of the
         month in which  such  transfer  is  effected,  provide  to the  Special
         Servicer  loan  level  information  (in the  loan  level  tape or other
         electronic  media or other  agreed-upon  form) regarding the Distressed
         Mortgage  Loan during the month of such transfer as may be necessary to
         enable  the  Special  Servicer  to  provide  such  information  in  its
         remittance  report for the next  following  month,  and (v) the Company
         shall be entitled  to its pro rata  portion of the  Servicing  Fee with
         respect  to any such  Distressed  Mortgage  Loan for the month in which
         such  transfer  occurs,  based on the number of days in such month that
         precede the Transfer Date."

18.      The following paragraph is added at the end of Section 12.01:

                  "Neither  the  Master  Servicer  nor  any  successor  servicer
         (including the Purchaser and the Master  Servicer)  shall be liable for
         any acts or omissions of the Company or any  predecessor  servicer.  In
         particular,  neither the Master  Servicer  nor any  successor  servicer
         (including the Purchaser and the Master  Servicer)  shall be liable for
         any servicing errors or interruptions resulting from any failure of the
         Company to maintain  computer  and other  information  systems that are
         year-2000 compliant."

19.      The following definition is hereby added:

                  "Prepayment Period: With respect to the first Remittance Date,
         the period  beginning  on the  Cut-off  Date and ending on July 1. With
         respect to each subsequent  Remittance  Date, the period  commencing on
         the second day of the month  immediately  preceding  the month in which
         such Remittance Date occurs and ending on the first day of the month in
         which such Remittance Date occurs."
