               (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
Agencies,  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 (but in no event more than 3 months
thereafter except to the extent delays are caused by the applicable  recording
office), the Trustee, at the expense of the Depositor and with the cooperation
of the Servicer,  shall cause to be properly  recorded by the Servicer 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,  or to the  applicable  Custodian on behalf of 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,  or to the
applicable Custodian on behalf of 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 (or in the form annexed to the applicable  Custodial  Agreement as
Exhibit B-1, as applicable).

         (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 and the Master Servicer an
Interim  Certification  in the form  annexed  hereto as Exhibit B-2 (or in the
form  annexed  to the  applicable  Custodial  Agreement  as  Exhibit  B-2,  as
applicable)  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 and the Master Servicer a
Final  Certification  substantially  in the form annexed hereto as Exhibit B-3
(or in the form annexed to the applicable  Custodial Agreement as Exhibit B-3,
as  applicable)  evidencing  the  completeness  of the  Mortgage  Files in its
possession or control, with any exceptions noted thereto.

         (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.

         (f) Each of the parties hereto  acknowledge  that the Custodian shall
perform  the   applicable   review  of  the  Mortgage   Loans  and  respective
certifications thereof, as provided in this Section 2.02.

         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,  at  the  expense  of the  Depositor  and  with  the
cooperation  of the  Servicer,  shall cause the  Assignment  of Mortgage  with
respect to such  Qualifying  Substitute  Mortgage  Loan to be  recorded by the
Servicer 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.

                                 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  will be issued in the minimum
denominations in Certificate  Principal Amount (or Notional Amount)  specified
in the Preliminary  Statement hereto and in integral multiples of $1 in excess
thereof.  Each Class of Non-Book  Entry  Certificates  other than the Residual
Certificate will be issued in definitive, fully registered form in the minimum
denominations  in Certificate  Principal  Amount  specified in the Preliminary
Statement  hereto  and in  integral  multiples  of $1 in excess  thereof.  The
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  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 (i) a Disqualified  Organization  or (ii) an individual,
corporation  or  partnership  or other person  unless such person is (A) not a
Non-U.S.  Person or (B) is a Non-U.S. Person that holds a Residual Certificate
in connection with the conduct of a trade or business within the United States
and has furnished the  transferor  and the Trustee with an effective  Internal
Revenue  Service  Form 4224 or  successor  form at the time and in the  manner
required  by the Code (any such person who is not covered by clause (A) or (B)
above is referred to herein as a "Non-permitted Foreign Holder").

         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,  an agent or nominee acting
on behalf of a Disqualified  Organization,  nor a Non-permitted Foreign Holder
(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,
agent or nominee thereof, or Non-permitted Foreign Holder. Notwithstanding the
registration  in the  Certificate  Register of any  transfer,  sale,  or other
disposition of a Residual Certificate to a Disqualified Organization, an agent
or nominee thereof,  or Non-permitted  Foreign Holder, such registration shall
be deemed to be of no legal force or effect  whatsoever and such  Disqualified
Organization,  agent or nominee thereof, or Non-permitted Foreign Holder 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, agent or nominee thereof, or Non-permitted Foreign Holder 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,  agent or nominee
thereof,  or  Non-permitted  Foreign Holder.  The Trustee shall be entitled to
recover  from any Holder of a  Residual  Certificate  that was a  Disqualified
Organization, agent or nominee thereof, or Non-permitted Foreign Holder at the
time it  became a  Holder  or any  subsequent  time it  became a  Disqualified
Organization,  agent or nominee thereof, or Non-permitted  Foreign Holder, 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
occurrence of an Event of Default,  Certificate Owners representing beneficial
interests  aggregating  not less than 50% of the Class  Certificate  Principal
Amount of a Class of Book-Entry Certificates identified as such to the Trustee
by an Officer's  Certificate  from the Clearing  Agency advise the Trustee and
the Clearing Agency through the Clearing  Agency  Participants in writing that
the  continuation  of a book-entry  system  through the Clearing  Agency is no
longer  in the  best  interests  of  the  Certificate  Owners  of a  Class  of
Book-Entry  Certificates,  the Trustee  shall notify or cause the  Certificate
Registrar  to  notify  the  Clearing  Agency  to  effect  notification  to all
Certificate Owners, through the Clearing Agency, of the occurrence of any such
event and of the availability of Definitive Certificates to Certificate Owners
requesting  the  same.  Upon  surrender  to  the  Trustee  of  the  Book-Entry
Certificates by the Clearing Agency,  accompanied by registration instructions
from the  Clearing  Agency  for  registration,  the  Trustee  shall  issue the
Definitive  Certificates.  Neither the  Transferor  nor the  Trustee  shall be
liable for any delay in delivery  of such  instructions  and may  conclusively
rely on, and shall be  protected  in relying on, such  instructions.  Upon the
issuance of  Definitive  Certificates  all  references  herein to  obligations
imposed upon or to be  performed by the Clearing  Agency shall be deemed to be
imposed  upon and  performed by the Trustee,  to the extent  applicable,  with
respect to such  Definitive  Certificates  and the Trustee shall recognize the
holders of the Definitive Certificates as Certificateholders hereunder.

                                  ARTICLE IV

                       ADMINISTRATION OF THE TRUST FUND

         Section 4.01. Collection Account. (a) On the Closing Date, the Master
                       ------------------
Servicer  shall open and shall  thereafter  maintain an account  held in trust
(the  "Collection  Account"),  entitled  "Aurora Loan Services Inc., as Master
Servicer,  in  trust  for the  benefit  of the  Holders  of  Structured  Asset
Securities Corporation Mortgage Pass-Through Certificates,  Series 1998-ALS2."
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.

         (b) The  Collection  Account  shall  be an  Eligible  Account.  If an
existing  Collection  Account  ceases to be an  Eligible  Account,  the Master
Servicer shall establish a new Collection  Account that is an Eligible Account
within 30 days and transfer all funds on deposit in such  existing  Collection
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.  On
each Deposit  Date,  the entire  amount on deposit in the  Collection  Account
(subject to permitted  withdrawals set forth in Section 4.02),  excluding such
amounts  not  included  in  the   Available   Distribution   Amount  for  such
Distribution  Date pursuant to clauses (a) through (g) 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 and late collections, 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. In the event the Master Servicer does not
provide written  direction to the Trustee pursuant to this Section,  all funds
on deposit in the Collection Account shall remain uninvested.

         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 or to the Seller,  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  distributions  of the  Retained  Interest  to the
         Retained Interest Holder on each Distribution Date;

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

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

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

               (xiii) 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

               (xiv) 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.

         Each  Servicer  shall be entitled to retain as  additional  servicing
compensation any Prepayment Penalty Amounts or Prepayment Interest Excess.

         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).

reasonable  efforts to obtain such  information  and  documentation  from such
Servicer,  and provide) to such  Certificateholder  such reports and access to

regulations,  a report  summarizing  the items provided to  Certificateholders
pursuant  to Section  4.03(a) on an annual  basis as may be required to enable
such Holders to prepare their  federal  income tax returns.  Such  information
shall include the amount of original issue  discount  accrued on each Class of
Certificates  and  information  regarding the expenses of the Trust Fund.  The
Master  Servicer  shall  provide  the  Trustee  with  such  information  as is
necessary for the Trustee to prepare such reports.

         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 may invest,  or cause to be  invested,  funds held in
the  Certificate  Account,  which  funds,  if  invested,  shall be invested 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.  Funds held in the  Certificate  Account that are not
invested shall be held in cash.

                        ------------------------
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,  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.  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).

         Prepayment Interest Shortfalls for the related Mortgage Pool for such
         Distribution Date; provided, however, that any shortfall in available
         amounts  for Pool 2 shall be  allocated  between  the  Classes of the
         related  Certificate  Group in  proportion  to the  amount of Accrued
         Certificate   Interest  (as  so  reduced)  that  would  otherwise  be
         distributable thereon;

               (iii) from the Available Distribution Amount for Pool 1, to the
         Class 1-A Certificates,  and from the Available  Distribution  Amount
         for Pool 2, to the Class 2-A and Class R Certificates,  respectively,
         any related Interest Shortfall for such Distribution Date;  provided,
         however,  that any  shortfall  in  available  amounts for each Pool 2
         shall be  allocated  between the  Classes of the related  Certificate
         Group in proportion to the Interest  Shortfall for each such Class on
         such Distribution Date;

               (iv) from the remaining  Available  Distribution Amount for the
         related Mortgage Pool, to the Senior Certificates of each Certificate

                       been reduced to zero;
          
                    (B) to the Class 2-A, Class 2-AP and Class R Certificates,
                  from  the  Available  Distribution  Amount  for  Pool  2 for

         Amount for the Class 1-AP and Class 2-AP  Certificates,  such  amount
         shall be  distributed  pro rata to such Classes on the basis of their
         respective Class AP Deferred Amounts; and

               (vi) from the remaining Available  Distribution Amount for both
         Mortgage Pools, subject to the prior distribution of amounts pursuant

               Amount  for such  Distribution  Date,  except  as  provided  in
               Section  5.02(c),   until  the  Certificate  Principal  Balance
               thereof has been reduced to zero.

         (b) Net  Prepayment  Interest  Shortfalls for a Mortgage Pool will be

interest accrued on the related Apportioned Principal Balances.

         (c) (i) If on any Distribution Date the Credit Support Percentage for

for such Class,  then,  notwithstanding  anything  to the  contrary in Section
5.02(a), no distribution of amounts described in clauses (ii) and (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 Certificates
on such Distribution Date. (ii) If on any Distribution Date the Credit Support
Percentage  for the Class B2  Certificates  is less than the  Original  Credit
Support  Percentage  for such  Class,  then,  notwithstanding  anything to the
contrary in Section 5.02(a),  no distribution of amounts  described in clauses
(ii) and (iii) of the definition of Subordinate Principal  Distribution Amount
will be made in  respect  of the  Class  B3,  Class  B4,  Class B5 or Class B6
Certificates on such Distribution  Date. (iii) If on any Distribution Date the
Credit  Support  Percentage  for the  Class B3  Certificates  is less than the
Original  Credit  Support  Percentage  for such Class,  then,  notwithstanding
anything  to the  contrary  in Section  5.02(a),  no  distribution  of amounts
described in clauses (ii) and (iii) of the definition of Subordinate Principal
Distribution Amount will be made in respect of the Class B4, Class B5 or Class
B6 Certificates on such  Distribution  Date. (iv) If on any Distribution  Date

Certificates on such  Distribution  Date. (v) If on any Distribution  Date the
Credit  Support  Percentage  for the  Class B5  Certificates  is less than the
Original  Credit  Support  Percentage  for such Class,  then,  notwithstanding
anything  to the  contrary  in Section  5.02(a),  no  distribution  of amounts
described in clauses (ii) and (iii) of the definition of Subordinate Principal
Distribution  Amount will be made in respect of the Class B6  Certificates  on
such Distribution Date.

         Any  amount  not   distributed   in  respect  of  any  Class  on  any
Distribution  Date pursuant to the  immediately  preceding  paragraph  will be
allocated  among the  remaining  Subordinate  Classes in  proportion  to their
respective Certificate Principal Amounts.

         (d) 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  (d) shall not reduce the Class
Certificate Principal Amount of the Class R Certificate.

         (e)  (i) On  each  Distribution  Date  prior  to the  Credit  Support
Depletion  Date  but on or  after  the date on  which  the  Class  Certificate
Principal  Amount  of the Group 1  Certificates  (other  than the  Class  1-AP
Certificates)  or the  Class  Certificate  Principal  Amount  of the  Group  2
Certificates  (other  than the Class 2-AP  Certificates)  has been  reduced to
zero,   amounts  otherwise   distributable  as  principal  on  each  Class  of
Subordinate Certificates pursuant to Section 5.02(a)(vi),  in reverse order of
priority,  in respect of such  Class's  Subordinate  Class  Percentage  of the
Subordinate  Principal  Distribution  Amount for the Mortgage Pool relating to
such retired  Certificates,  will be distributed as principal to the remaining
Group  1 or  Group  2  Certificates  (as  applicable),  provided  that on such
Distribution   Date  (a)  the  Aggregate   Subordinate   Percentage  for  such
Distribution Date is less than 200% of the Aggregate Subordinate Percentage as
of the Cut-off Date or (b) the average  outstanding  principal  balance of the
Mortgage  Loans in either  Mortgage Pool which are  delinquent 60 days or more
over the last six months as a  percentage  of the  related  Group  Subordinate
Amount is greater than or equal to 50%.

               (ii)  If,  on  any  Distribution   Date  a  Certificate   Group
         constitutes  an  Undercollateralized  Group,  all  amounts  otherwise
         distributable  as  principal  on  the  Subordinate  Certificates,  in
         reverse order of priority (other than amounts  necessary to pay Class
         AP Deferred Amounts or unpaid Interest Shortfalls) (or, following the
         Credit Support  Depletion Date,  such other amounts  described in the
         following sentence),  will be distributed as principal to the Class A
         Certificates   (other  than  the  Class  AP   Certificates)   of  the
         Undercollateralized  Group,  until the  aggregate  Class  Certificate
         Principal    Amount   of   such   Class   A   Certificates   of   the
         Undercollateralized  Group  equals  the  Non-AP  Pool  Balance of the
         related Mortgage Pool (such amounts,  "Undercollateralized Amounts").
         In   the   event   that   a   Certificate    Group   constitutes   an
         Undercollateralized  Group on any  Distribution  Date  following  the
         Credit Support  Depletion Date,  Undercollateralized  Amounts will be
         paid from the  excess  of the  Available  Distribution  Amount of the
         other  Mortgage Pool remaining  after all required  amounts have been
         distributed  to the Class A  Certificates  of such other  Certificate
         Group. In addition, the amount of any unpaid Interest Shortfalls with
         respect  to an  Undercollateralized  Group on any  Distribution  Date
         (including any Interest  Shortfalls for such Distribution  Date) will
         be distributed to the Class A Certificates  (other than any Principal
         Only  Certificates)  of the  Undercollateralized  Group  prior to the
         payment of any  Undercollateralized  Amount  from  amounts  otherwise
         distributable  as  principal  on  the  Subordinate  Certificates,  in
         reverse order of priority (or, following the Credit Support Depletion
         Date, as provided in the preceding sentence).

         Section 5.03.  Allocation of Realized Losses. (a) On any Distribution
                        -----------------------------
Date,  (x) the  applicable  AP  Percentage  of the  principal  portion of each
Realized  Loss  (other  than  any  Excess  Loss)  in Pool 1 and Pool 2 will be
allocated to the Class 1-AP and Class 2-AP Certificates,  respectively,  until
the Class  Certificate  Principal Amount thereof has been reduced to zero; and
(y) the applicable Non-AP Percentage of 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 priority:

                        first, to the Class B6  Certificates,  until the Class
                  Certificate  Principal  Amount  thereof has been  reduced to
                  zero;

                        second, to the Class B5 Certificates,  until the Class
                  Certificate  Principal  Amount  thereof has been  reduced to
                  zero;

                        third,  to  the  Class  B4  Certificates,   until  the
                  Component Principal Amount thereof has been reduced to zero;

                        fourth, to the Class B3 Certificates,  until the Class
                  Certificate  Principal  Amount  thereof has been  reduced to
                  zero;

                        fifth, to the Class B2  Certificates,  until the Class
                  Certificate  Principal  Amount  thereof has been  reduced to
                  zero;

                        sixth, to the Class B1  Certificates,  until the Class
                  Certificate  Principal  Amount  thereof has been  reduced to
                  zero; and

                        seventh,  to the Classes of Senior Certificates of the
                  related  Certificate  Group,  pro rata, in  accordance  with
                  their Class Certificate  Principal Amounts;  provided,  that
                  any such loss allocated to any 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  applicable  Non-AP
Percentage  of the  principal  portion  of any  Excess  Loss in  respect  of a
Mortgage Loan shall be allocated,  pro rata, to the  Subordinate  Certificates
(regardless  which pool experienced the loss) and Group 1 Certificates (in the
case of a Realized Loss in Pool 1) or Group 2  Certificates  (in the case of a
Realized  Loss  in  Pool  2) and on the  basis  of the  Apportioned  Principal
Balances  of the Classes of  Subordinate  Certificates  and Class  Certificate
Principal  Amounts of the Senior  Certificates;  provided,  that any such loss
allocated  to any Class of Accrual  Certificates  (and any Accrual  Component)
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 Amount
thereof on the Closing  Date (as  reduced by any  Realized  Losses  previously
allocated  thereto).  The Applicable AP Percentage of the principal portion of
an Excess  Loss in Pool 1 and Pool 2 will be  applied  to the  Class  1-AP and
Class 2-AP Certificates,  respectively,  until the Class Certificate Principal
Amount thereof has been reduced to zero.

         (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,
except that the  aggregate  amount of Realized  Losses to be  allocated to the
Class 1-AP and Class 2-AP Certificates on such Distribution Date will be taken
into  account  in  determining  distributions  in  respect  of any Class  1-AP
Deferred Amount or Class 2-AP Deferred amount, as applicable for such 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, to be set forth in an Officer's
Certificate to be delivered to the Trustee on such  Determination  Date, 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  immediately
available  funds in 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 immediately available 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,  as successor  Master Servicer  pursuant to Section
6.14,  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  (of which a  Responsible  Officer of the
Trustee  shall have actual  knowledge),  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  (of  which a
Responsible  Officer of the Trustee shall have actual  knowledge) 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,  and shall  not be  required  to  recalculate  or verify  any
numerical information furnished 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

         (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, 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
         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; and

               (iv)  The  Trustee  shall  not be  responsible  for  any act or
         omission of the Master Servicer. In particular, the Trustee shall not
         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.

         (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 not be required to expend or risk its own funds
or otherwise  incur  financial  liability  for the  performance  of any of its
duties  hereunder  or 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 Master  Servicer  or any  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.  (g)
Subject to Section 4.04, the Trustee shall not be held liable by reason of any
insufficiency  in any account  (including  without  limitation  the Collection
Amount) held by or on behalf of the Trustee resulting from any investment loss
on any Eligible  Investment  included  therein  (except to the extent that the
Trustee is the obligor and has defaulted thereon).

         (h) Except as otherwise  provided  herein,  the Trustee shall have no
duty (A) to see to any recording,  filing,  or depositing of this Agreement or
any agreement  referred to herein or any financing  statement or  continuation
statement evidencing a security interest,  or to see to the maintenance of any
such  recording or filing or depositing or to any  re-recording,  re-filing or
re-depositing of any thereof,  (B) to see to any insurance,  (C) to see to the
payment or discharge of any tax,  assessment,  or other governmental charge or
any lien or encumbrance of any kind owing with respect to,  assessed or levied
against,  any part of the Trust Fund other  than from funds  available  in the
Collection Account or the Certificate Account, or (D) to confirm or verify the
contents of any reports or certificates  of the Master  Servicer  delivered to
the Trustee  pursuant to this Agreement  believed by the Trustee to be genuine
and to have been signed or presented by the proper party or parties.

         (i) The Trustee shall not be liable in its individual capacity for an
error  of  judgment  made in good  faith  by a  Responsible  Officer  or other
officers  of the  Trustee,  unless it shall be  proved  that the  Trustee  was
negligent in ascertaining the pertinent facts.

         (j) Notwithstanding  anything in this Agreement to the contrary,  the
Trustee shall not be liable for special,  indirect or consequential  losses or
damages of any kind whatsoever (including,  but not limited to, lost profits),
even if the Trustee has been advised of the  likelihood of such loss or damage
and regardless of the form of action.

         Holders of at least a majority in Class Certificate  Principal 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

         hereto, in each case at the request, order or direction of any of the
         Certificateholders  pursuant  to the  provisions  of this  Agreement,
         unless  such  Certificateholders  shall have  offered to the  Trustee
         reasonable  security or  indemnity  against the costs,  expenses  and
         liabilities which may be incurred therein or thereby;

               (vii) The right of the Trustee to perform any discretionary act
         enumerated in this  Agreement  shall not be construed as a duty,  and

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

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

requirement,  restriction  or  condition  in any  state  in  which a  property

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

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.

extent  permitted  by law,  be  appointed  and act  subject  to the  following

         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

         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. The Trustee shall
not be  responsible  for any  action  or  inaction  of any  separate  trustee,
co-trustee  or  custodian.  If any separate  trustee,  co-trustee or custodian

         (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).

                        ---------------------
or more  Authenticating  Agents which shall be  authorized to act on behalf of

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.  The Trustee  shall be
                         -----------------------------
entitled to the Trustee Fee (which  shall not be limited by any  provision  of
law in regard to the  compensation of a trustee of an express  trust),  to the
extent  provided  herein,  and in addition,  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
                         -----------------------------------------------------

         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  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 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 of each Class of Certificates;

               (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  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 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.
For all purposes of this  Agreement,  in the absence of actual  knowledge by a
Responsible  Officer of the Trustee,  the Trustee  shall not be deemed to have
knowledge of any failure of the Master  Servicer or any other Event of Default
unless  notified  in  writing  by the  Depositor,  the  Master  Servicer  or a
Certificateholder.

         Section 6.20.  Preparation of Tax Returns and Other Reports.  (a) The
                        --------------------------------------------
Trustee  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  directly  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  Trustee  shall  prepare and file with the  Internal  Revenue
Service ("IRS"), on behalf of the Trust Fund, an application on IRS Form SS-4.
The   Trustee,   upon   receipt  from  the  IRS  of  the  Notice  of  Taxpayer
Identification  Number Assigned,  shall promptly forward a copy of such notice
to the Master Servicer and the Depositor.

         (c) The  Depositor  shall prepare or cause to be prepared the initial
current report on Form 8-K and thereafter the Trustee 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"), and the Trustee will sign each such report on behalf of the Trust. The
Trustee  will  forward a copy of each such  report to the  Depositor  promptly
after such report has been filed with the SEC.  The Trustee  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 Trustee 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.

                           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);
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 (i)
the  Trustee to sell (or arrange for the sale of) the assets of the Trust Fund
and (ii) 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 appointed by the Master Servicer with the consent of 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.

         (c) Any  reasonable  expenses  incurred by the Trustee in  connection
with any  termination  or  liquidation  of the Trust  Fund  shall be paid from
proceeds received from the liquidation of the Trust Fund.

         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 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 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.

                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  Aurora Loan
Services Inc., 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 Fidelity Bond and an 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 Errors  and  Omissions  Insurance  Policy and the
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  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.  The  Fidelity  Bond and  Errors  and
Omissions Insurance Policy may be obtained and maintained in blanket form.

         (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 either act as Servicer of the
related  Mortgage Loans, or enter into a Servicing  Agreement with a successor
Servicer.

         (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;  provided  that the  Master  Servicer  shall not
indemnify or hold harmless the Trustee  against  negligent or wrongful acts or
omissions of the Trustee.

         (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
         jurisdiction of its formation,  and as Master Servicer has full power
         and authority to 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 or
         any  other  corporate  restriction  or  any  judgment,  order,  writ,
         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;

               (vi) no  litigation  is  pending  or, to the best of the Master
         Servicer's  knowledge,  threatened  against the Master Servicer 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
         the Master  Servicer with this Agreement or the  consummation  of the
         transactions   contemplated  by  this  Agreement,   except  for  such
         consents, approvals,  authorizations and orders (if any) as have been
         obtained;

               (ix) the consummation of the transactions  contemplated by this
         Agreement  are in the  ordinary  course  of  business  of the  Master
         Servicer; and

               (x) the Master  Servicer has  obtained an Errors and  Omissions
         Insurance Policy and a Fidelity Bond in accordance with Section 9.02,
         each of which is in full force and effect, and each of which provides
         at least such coverage as is required hereunder.

         (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).  Notwithstanding
anything in this Agreement to the contrary,  the Master  Servicer shall not be
liable for special,  indirect or  consequential  losses or damages of any kind
whatsoever (including, but not limited to, lost profits). 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
by each Servicer,  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 non-coverage  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. The Master
                        ------------------------------------------
Servicer shall use its  reasonable  best efforts to, or to cause each 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 (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. The Master Servicer shall use its reasonable
best efforts to sell, or, to the extent  provided in the applicable  Servicing
Agreement,  cause  the  applicable  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 applicable  Servicer
to protect and  conserve,  such REO  Property in the manner and to such extent
required by the applicable Servicing Agreement, subject to Article X hereof.

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

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, 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.

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

Master  Servicer  shall  deliver to the Trustee and the Rating  Agencies on or

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, (iii) 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 (iv)
the Master  Servicer has received from each Servicer  such  Servicer's  annual

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 Agencies 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

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  Agencies  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

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.

                             REMIC ADMINISTRATION

         Section 10.01. REMIC Administration.  (a) An election will be made by
                        --------------------
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  Trustee  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 Trustee in  fulfilling  its
duties hereunder  (including its duties as tax return  preparer).  The Trustee
shall be entitled  to  reimbursement  of  expenses  to the extent  provided in
clause (i) above from the Certificate Account.

         (d) The Trustee  shall  prepare,  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 Trustee.

         (e) The Trustee 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 Trustee  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 Trustee  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) Upon the request of any Rating Agency,  the Trustee shall deliver
to  such  Rating  Agency  an  Officer's   Certificate  stating  the  Trustee'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 Trustee of its duties and
obligations  set forth herein,  the Trustee 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 Trustee shall not be liable for any such Losses attributable to the action
or  inaction  of the Master  Servicer,  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 Trustee 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 Trustee 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 Trustee 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  applicable
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  applicable  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
applicable  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  applicable  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 applicable
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) 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.

                           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 11.04.  Voting 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

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)
under the Act. Any reasonable,  out-of-pocket expenses incurred by the Trustee
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

reference in the Prospectus. Any reasonable out-of-pocket expenses incurred by
the Trustee in providing  copies of such documents  shall be reimbursed by the
Depositor.

be  delivered  by  first  class  mail to the  Depositor,  Attention:  Contract
Finance,  a copy of the report  delivered  to  Certificateholders  pursuant to

         punctual performance and observance of each covenant and condition to
         be  performed  and  observed  by the  Servicer  under the  applicable
         Servicing Agreement;

               (iv) There must be  delivered to the Trustee a letter from each
         Rating Agency to the effect that such transfer of servicing  will not

               (v) The Seller shall, at its cost and expense, take such steps,

         required notices or disclosures  describing the transfer of servicing
         of the Mortgage  Loans to the  successor  servicer;  (B) prior to the
         effective date of such transfer of servicing,  the Seller shall cause
         the prior Servicer to transmit to any related insurer notification of
         such transfer of servicing;  (C) on or prior to the effective date of
         such transfer of servicing, the Seller shall cause the prior Servicer
         to deliver to the successor  servicer all Mortgage Loan Documents and
         any related  records or  materials;  (D) on or prior to the effective
         date of such transfer of servicing,  the Seller shall cause the prior
         Servicer to transfer to the successor servicer,  or, if such transfer
         occurs after a Remittance Date but before the next succeeding Deposit
         Date,  to the  Master  Servicer,  all funds held by the  Servicer  in
         respect of the Mortgage Loans;  (E) on or prior to the effective date
         of such  transfer  of  servicing,  the Seller  shall  cause the prior

         the  successor  servicer,  continue  to  forward  to  such  successor
         servicer,  within  one  Business  Day of  receipt,  the amount of any
         payments or other recoveries  received by the prior Servicer,  and to
         notify the successor servicer of the source and proper application of
         each such  payment or  recovery;  and (F) the Seller  shall cause the
         prior  Servicer to, after the effective date of transfer of servicing
         to the successor  servicer,  continue to cooperate with the successor
         servicer  to  facilitate  such  transfer  in such  manner and to such
         extent as the successor servicer may reasonably request.

Dear Sirs:

         In connection with our proposed purchase of $______________ principal
amount of Mortgage Pass-Through Certificates, Series 1998-ALS2 (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  December  1, 1998  among the
         Depositor,  Aurora Loan Services  Inc.,  as Master  Servicer and U.S.
         Bank  National  Association,  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.

     All capitalized terms not defined herein shall have the same meanings
assigned to such terms in that certain Trust Agreement (the "Trust

identified on the Mortgage Loan Schedule attached hereto as Exhibit A:

     1. Mortgage Loan Purchase and Warranties Agreement, dated as of November
30, 1998, between Lehman Capital and Headlands Mortgage Company; and

     2. Loan Purchase Agreement (Servicing Released), dated March 23, 1998,
between Lehman Capital and Aurora Loan Services Inc.

     WHEREAS, each Transfer Agreement permits the purchaser to assign its
rights and interests in such agreement and to delegate its obligations
thereunder;

     WHEREAS, Lehman Capital desires to sell, without recourse, all of its
right, title and interest in the Mortgage Loans to the Depositor, to assign
all of its rights and interest under each Transfer Agreement, and to delegate
all of its obligations thereunder, to the Depositor; and

     WHEREAS, Lehman Capital and the Depositor acknowledge and agree that the

hereunder to the Trustee, and that each reference herein to the Depositor is
intended, unless otherwise specified, to mean the Depositor or the Trustee, as

     NOW, THEREFORE, in consideration of the mutual agreements herein set
forth, and for other good and valuable consideration, the receipt and adequacy
of which are hereby acknowledged, Lehman Capital and the Depositor agree as
follows:

                                  ARTICLE I.

                         CONVEYANCE OF MORTGAGE LOANS

     Section 1.01. Sale of Mortgage Loans. Concurrently with the execution and
delivery of this Agreement, Lehman Capital does hereby transfer, assign, set

all the right, title and interest of Lehman Capital in and to the Mortgage

by the related Mortgagors to be applied after such date, together with all of
Lehman Capital's right, title and interest in and to each related account and
all amounts from time to time credited to and the proceeds of such account,
any REO Property and the proceeds thereof, Lehman Capital's rights under any

including the Mortgaged Properties and any Additional Collateral.

     Concurrently with the execution and delivery of this Agreement, Lehman
Capital hereby assigns to the Depositor all of its rights and interest under
each Transfer Agreement, and delegates to the Depositor all of its obligations
thereunder. Concurrently with the execution hereof, the Depositor tenders the
purchase price of $259,686,395.01. The Depositor hereby accepts such
assignment and delegation, and shall be entitled to exercise all such rights
of Lehman Capital under each Transfer Agreement, as if the Depositor had been

     Section 1.02. Delivery of Documents. (a) In connection with such transfer
and assignment of the Mortgage Loans hereunder, Lehman Capital does hereby
deliver, or cause to be delivered, to the Depositor (or its designee) the

File") so transferred and assigned, as specified in the applicable Transfer
Agreement.

     (b) For Mortgage Loans (if any) that have been prepaid in full after the
Cut-off Date and prior to the Closing Date, Lehman Capital, in lieu of
delivering the related Mortgage Files, herewith delivers to the Depositor an

Custodian identifies any Material Defect, Lehman Capital shall be obligated to
cure such defect or to repurchase the related Mortgage Loan from the Depositor
(or, at the direction of and on behalf of the Depositor, from the Trust Fund),
or to substitute a Qualifying Substitute Mortgage Loan therefor, in each case
to the same extent and in the same manner as the Depositor is obligated to the
Trustee and the Trust Fund under Section 2.02(c) of the Trust Agreement.

     hereof;

          (iv) this Agreement has been duly executed and delivered by Lehman
     Capital and, assuming due authorization, execution and delivery by the

     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 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, 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. 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 lien 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 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. Section 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.

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

each Class of Certificates affected thereby for the purpose of adding any

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

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

                            MORTGAGE LOAN SCHEDULE



                              SERVICING AGREEMENT

     THIS SERVICING AGREEMENT (this "Agreement"), entered into as of the 1st
day of December, 1998, by and between LEHMAN CAPITAL, A DIVISION OF LEHMAN
BROTHERS HOLDINGS INC., a Delaware corporation ("Lehman Capital"), and AURORA
LOAN SERVICES INC., a Delaware corporation ("the Servicer"), recites and
provides as follows:

                                   RECITALS

     WHEREAS, Lehman Capital has conveyed certain Mortgage Loans identified on
Schedule I hereto (the "Serviced Mortgage Loans") on a servicing-retained
basis to Structured Asset Securities Corporation ("SASCO"), which in turn has
conveyed the Serviced Mortgage Loans to U.S. Bank National Association, as
trustee (the "Trustee") under a trust agreement dated as of December 1, 1998
(the "Trust Agreement"), among the Trustee, Aurora Loan Services Inc., as
master servicer ("Aurora," and together with any successor Master Servicer
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, Aurora, acting as Master Servicer, and any successor Master
Servicer shall be obligated, among other things, to supervise the servicing of
the Serviced Mortgage Loans on behalf of the Trustee, and shall have the
right, under certain circumstances, to terminate the rights and obligations of
the Servicer under this 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 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 Flow Servicing Agreement
dated as of September 1, 1997, between Lehman Capital and the Servicer (the
"Flow Servicing Agreement") incorporated by reference herein, shall have the
meanings ascribed to such terms in the Trust Agreement.

     2. Servicing. The Servicer agrees, with respect to the Serviced Mortgage
Loans, to perform and observe the duties, responsibilities and obligations
that are to be performed and observed under the provisions of the Flow
Servicing Agreement, except as otherwise provided herein and on Exhibit A
hereto, and that the provisions of the Flow 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 Servicer. The Servicer, including any
successor servicer hereunder, shall be subject to the supervision of the
Master Servicer, which Master Servicer shall be obligated to ensure that the
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 Flow Servicing Agreement) to enforce the
obligations of the Servicer under the Flow Servicing Agreement. In addition,
all of the representations, warranties, covenants, agreements and indemnities
made by the Servicer (or by any successor servicer) to the "Owner" under the
Flow Servicing Agreement are hereby deemed made to the Master Servicer as if
the Master Servicer were the "Owner" and all such representations, warranties,
covenants, agreements and indemnities shall inure to the benefit of the Master
Servicer; provided, however, that notwithstanding the foregoing, the Master
Servicer shall have (i) no right or interest in the "Reconstituted Termination
Fee" referred to in Section 7.06 of the Flow Servicing or the "Additional
Remittance" referred to in Section 7.07 of the Flow Servicing Agreement and
(ii) no right to terminate the Servicer, except as expressly set forth herein.
Nothing contained herein is intended to result in the creation or assumption
by the Master Servicer of any obligation of the "Owner" or any Person under
the Flow Servicing Agreement or any other agreement or instrument relating
thereto except as specifically set forth herein. The Master Servicer shall be
entitled to terminate the rights and obligations of the Servicer under this
Agreement upon the failure of the Servicer to perform any of its obligations
under this Agreement, as provided in Article IX of the Flow Servicing
Agreement.

     In addition, in the event that Lehman Capital transfers the servicing
rights in respect of the Serviced Mortgage Loans to one or more successor
servicers, the rights and obligations of the Servicer under this Agreement
shall terminate, at the sole option of Lehman Capital, without cause, upon
thirty days written notice to the Servicer, and each successor servicer shall
succeed to the rights and obligations of the Servicer under this Agreement as
of such date. Upon such termination the terminated Servicer shall not be
entitled to the Reconstituted 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.

     The Servicer agrees that, notwithstanding anything to the contrary in the
Flow Servicing Agreement, Lehman Capital is the sole owner of the servicing
rights relating to the Serviced Mortgaged Loans, and the Servicer shall have
no right to transfer the servicing thereof.

     4. No Representations. Neither the 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 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 Servicer agree that this
Agreement is a Reconstitution Agreement, and that the date hereof is the
Reconstitution Date, each as defined in the Flow Servicing Agreement.

     9. Notices and Remittances to the Master Servicer. All notices required
to be delivered to the Owner or the Master Servicer under this Agreement shall
be delivered to the Master Servicer at the following address:

        Aurora Loan Services Inc.
        2530 South Parker Road
        Suite 601
        Aurora, Colorado
        Attn:  Master Servicing Department, SASCO 1998-ALS2

     All remittances required to be made to the Master Servicer under this
Agreement shall be made to the following wire account:

        The Chase Manhattan Bank
        New York, New York
        ABA#:  021-000-021
        Account Name:  Aurora Loan Services Inc. Master Servicing Payment

        Beneficiary:  Aurora Loan Services Inc.
        For further credit to:  SASCO 1998-ALS2

     10. Errors and Omissions Insurance. The Servicer shall keep in force
during the term of this Agreement a fidelity bond and a policy or policies of
insurance covering errors and omissions in the performance of the Servicer's
obligations under this Agreement. Such fidelity bond and policy or policies
shall be maintained with recognized insurers and shall be in such form and
amount as would permit the Servicer to be qualified as a FNMA or FHLMC
seller-servicer. The Servicer shall be deemed to have complied with this
provision if an affiliate of the Servicer has such errors and omissions and
fidelity bond coverage and, by the terms of such insurance policy or fidelity
bond, the coverage afforded thereunder extends to the Servicer. The Servicer
shall furnish to the Master Servicer a copy of each such bond and insurance
policy if (i) the Master Servicer so requests and (ii) the Servicer is not an
affiliate of Lehman Brothers Inc. at the time of such request.

     11. Annual Audit Report. On or before April 30 of each year, beginning
with April 30, 1999, Servicer shall cause a firm of independent public
accountants (who may also render other services to Servicer), which is a
member of the American Institute of Certified Public Accountants, to furnish a
statement to Owner 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 the Owner and Master Servicer a Servicing Officer's certificate stating, as
to each signer thereof, that (i) a review of the activities of the Servicer
during such preceding fiscal year and of performance under this Agreement has
been made under such officers' supervision, and (ii) to the best of such
officers' knowledge, based on such review, the 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 the nature and status thereof including the
steps being taken by the Servicer to remedy such default.

          "Consistent with the terms of this Agreement, the Servicer may waive
     any late payment charge, assumption fee or other fee that may be
     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 payment of
     principal or interest, reduce or increase the outstanding principal
     balance (except for actual payments of principal) or change the final
     maturity date on such Mortgage Loan. In the event of any such
     modification which permits the deferral of interest or principal 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 difference between (a) such
     month's principal and one month's interest at the Remittance Rate on the
     unpaid principal balance of such Mortgage 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 generality of the foregoing, the
     Servicer shall continue, and is hereby authorized and empowered, to
     execute and deliver on behalf of itself and the Master Servicer, all
     instruments of satisfaction or cancellation, or of partial or full
     release, discharge and all other comparable instruments, with respect to
     the Mortgage Loans and with respect to the Mortgaged Properties. Upon the
     request of the Servicer, the Master Servicer shall execute and deliver to
     the Servicer any powers of attorney and other documents, furnished to it
     by the Servicer and reasonably satisfactory to the Master Servicer,
     necessary or appropriate to enable the Servicer to carry out its
     servicing and administrative duties under this Agreement.

          Notwithstanding anything to the contrary in this Agreement, the
     Servicer shall not waive any premium or penalty in connection with a
     prepayment of principal of any Mortgage Loan, and shall not consent to

     modification relates to payment of a prepayment premium or penalty."

     Mortgage Loan being limited to related Liquidation Proceeds, 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 Servicer from the Mortgagor or otherwise
