                            ISSUANCE OF CERTIFICATES

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

     Concurrently  with  the  execution  and  delivery  of this  Agreement,  the
Depositor does hereby assign to the Trustee all of its rights and interest under
the  Mortgage  Loan Sale and  Assignment  Agreement,  which  include  all of the
Depositor's  rights and interests  under each Sale and Servicing  Agreement (but
which do not include the rights of Lehman Capital under Section 11.12  thereof),
and  delegates  its  obligations  under the  Mortgage  Loan Sale and  Assignment
Agreement,  which include the  obligations of Lehman Capital under each Sale and
Servicing  Agreement,  (which rights and interests  have been assigned and which
obligations  have been delegated to the Depositor by Lehman Capital  pursuant to
the Mortgage Loan Sale and  Assignment  Agreement)  to the Trustee.  The Trustee
hereby accepts such assignment and delegation, and shall be entitled to exercise
all such rights of the  Depositor  under the Mortgage  Loan Sale and  Assignment
Agreement and each Sale and Servicing Agreement as if, for such purpose, it were
the Depositor.

     (b) In connection  with such transfer and  assignment,  the Depositor  does
hereby  deliver to, and deposit  with, or cause to be delivered to and deposited
with,  the  Custodian,  acting  on  behalf  of the  Trustee,  the  documents  or
instruments  with  respect to each  Mortgage  Loan (each a  "Mortgage  File") so
transferred  and assigned as are specified in the applicable  Sale and Servicing
Agreement.

     The  parties  hereto  acknowledge  and agree  that the form of  endorsement
attached  hereto as  Exhibit  B-2 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, the Trustee shall cause the  Custodian,  at
the expense of the  Depositor,  to cause to be properly  recorded in each public
recording office where the Mortgages are recorded each Assignment of Mortgage.

     (d) 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-referenced  documents,  herewith delivers or causes to be delivered to
the Trustee an  Officer's  Certificate  which shall  include a statement  to the
effect that all amounts  received in connection  with such  prepayment  that are
required to be deposited in the  Custodial  Account  maintained  by the Servicer
pursuant to the applicable Sale and Servicing  Agreement have been so deposited.


     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 (by it or by the  Custodian)  of the Mortgage  Files  pertaining  to the
Mortgage Loans listed on the Mortgage Loan  Schedule,  subject to any defects or
exception  noted in the Initial  Certification  (as  defined  below) and further
subject to the review  thereof by the  Custodian  in its capacity as designee of
the  Purchaser  under each Sale and  Servicing  Agreement  and to the  Trustee's
review thereof as specified herein.  The Custodian  executed and delivered as of
April  30,  1998,  an  initial   certification  (the  "Initial   Certification")
certifying as to its receipt of the documents  required to be delivered pursuant
to the applicable  Sale and Servicing  Agreement and  identifying any defects in
such  documents,  and delivered such  certification  to the Depositor and to The
Boston Company.  Pursuant to Section 2.03 of each Sale and Servicing  Agreement,
The Boston  Company is obligated to cure any Material  Defect (as defined in the
applicable   Sale  and   Servicing   Agreement)   identified   in  such  Initial
Certification,  or to repurchase the related Mortgage Loan or substitute another
mortgage loan therefor, within 60 days of receipt of such Initial Certification.

     (b) Prior to the first  anniversary  of the Closing Date, the Trustee shall
deliver  (or  cause  its   custodian  to  deliver)  to  the  Depositor  a  Final
Certification substantially in the form annexed hereto as Exhibit B-1 evidencing
the completeness of the Mortgage Files in its possession or control.

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

     Section 2.03.  Representations  and  Warranties of the  Depositor.  (a) The
Depositor hereby represents and warrants to the Trustee,  as of the Closing Date
or such other date as is specified, that:

          (i) 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;

          (ii) 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;
    
          (iii) 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;

          (iv)  this  Agreement  has been duly  executed  and  delivered  by the
     Depositor and,  assuming due  authorization,  execution and delivery by the
     Trustee,  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;

          (v) 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;  and  

          (vi) 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.  

     (b) The  representations  and warranties of The Boston Company with respect
to the related  Mortgage Loans in the applicable  Sale and Servicing  Agreement,
which have been  assigned  to the  Trustee  hereunder,  were made as of the date
specified in the applicable Sale and Servicing 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 The Boston Company under the applicable
Sale and  Servicing  Agreement and (ii) a  representation  or warranty of Lehman
Capital under the Mortgage Loan Sale and Assignment Agreement, the only right or
remedy of the Trustee or of any  Certificateholder  shall be the Trustee's right
to  enforce  the   obligations  of  The  Boston  Company  under  any  applicable
representation  or  warranty  made by it.  The  Trustee  acknowledges  that  the
representations  and  warranties  of Lehman  Capital in  Section  1.04(b) of the
Mortgage  Loan Sale and  Assignment  Agreement are  applicable  only to facts or
conditions  that arise or events that occur  subsequent  to the date as of which
the  representation and warranties with respect to the related Mortgage Loans in
the Sale and  Servicing  Agreements  were made,  and which do not  constitute  a
breach of any  representation  or warranty made by The Boston Company in Section
3.02 of the applicable Sale and Servicing  Agreement.  The Trustee  acknowledges
that 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 Boston Company in Section
3.02 of the applicable Sale and Servicing  Agreement,  without regard to whether
The Boston  Company  fulfills  its  contractual  obligations  in respect of such
representation or warranty.  The Trustee further acknowledges that the Depositor
shall  have no  obligation  or  liability  with  respect  to any  breach  of any
representation  or warranty  with respect to the Mortgage  Loans  (except as set
forth in Section 2.03(a)(vi)) under any circumstances.

     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 Boston Company and Lehman Capital  assigned to the Trustee
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  or the Trustee of a
breach of any of the  representations  and  warranties set forth in Section 2.03
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
party.  Within 90 days of the  discovery  of such a breach  with  respect to the
representations and warranties given to the Trustee by the Depositor or given by
Lehman Capital and assigned to the Trustee,  the Depositor or Lehman Capital, 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.  In  the  event  of  discovery  of  a  breach  of  any
representation  and warranty of The Boston Company assigned to the Trustee,  the
Trustee  shall  enforce  its  rights  under the  applicable  Sale and  Servicing
Agreement for the benefit of Certificateholders.

     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,  by The  Boston  Company  pursuant  to  either  Sale and  Servicing
Agreement or by Lehman Capital pursuant to the Mortgage Loan Sale and Assignment
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 Certificate Account. The Trustee,  upon receipt of
the full amount of the applicable 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  (and  any  applicable  Substitution
Amount),  shall  release or cause to be released and reassign to the  Depositor,
The Boston Company or Lehman Capital,  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 such  party  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)
at the Depositor's expense, 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,  The
Boston Company or Lehman Capital, as applicable, 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,  The
Boston Company or Lehman  Capital,  as  applicable,  will be deemed to have made
with  respect  to  such   Qualified   Substitute   Mortgage  Loan  each  of  the
representations  and warranties  made by it with respect to the related  Deleted
Mortgage  Loan.  As soon as  practicable  after the  delivery of any  Qualifying
Substitute  Mortgage Loan  hereunder,  the Trustee shall cause the Assignment of
Mortgage with respect to such Qualifying Substitute Mortgage Loan to be recorded
if required pursuant to the first sentence of Section 2.01(c).

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

     Section 2.06.  Converted  Mortgage Loans.  The Trustee  acknowledges  that,
pursuant  to the  applicable  Sale and  Servicing  Agreement,  the  Servicer  is
obligated  to  purchase  any  Converted  Mortgage  Loan from the  Trust  Fund or
substitute  another  mortgage  loan  therefor.  In the event  that the  Servicer
defaults on its  obligation  to purchase any  Converted  Mortgage  Loan from the
Trust Fund (or to substitute another mortgage loan), the Trustee will attempt to
sell such  Converted  Mortgage Loan, but only at a price at which the Trust Fund
would receive a net amount at least equal to the Repurchase  Price  specified in
the  applicable  Sale and Servicing  Agreement.  Until sold at such price,  each
Converted  Mortgage Loan will remain in the Trust Fund with the applicable fixed
Mortgage Rate.

     Section  2.07.  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 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  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 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 $1,000 in  excess  thereof.  Each  Residual  Certificate  will be issued as a
single  Certificate  and maintained in definitive,  fully  registered  form in a
minimum denomination equal to 100% of the Percentage Interest of such Class. The
Certificates  may be  issued  in  the  form  of  typewritten  certificates.  One
Certificate of each Class of  Certificates  other than the Residual  Certificate
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,  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)  No  transfer  of an  ERISA-Restricted  Certificate  in the  form  of a
Definitive  Certificate  shall be made to any  Person  unless  the  Trustee  has
received (A) a  certificate  substantially  in the form of Exhibit H hereto from
such transferee or (B) an Opinion of Counsel satisfactory to the Trustee and the
Depositor to the effect that the purchase and holding of such a Certificate will
not  constitute  or result in the assets of the Trust  Fund  being  deemed to be
"plan  assets"  subject to the  prohibited  transactions  provisions of ERISA or
Section  4975 of the Code and will not subject the Trustee or the  Depositor  to
any  obligation  in addition to those  undertaken  in the  Agreement;  provided,
however,  that the Trustee will not require such  certificate  or opinion in the
event that, as a result of a change of law or otherwise, counsel satisfactory to
the Trustee has  rendered an opinion to the effect that the purchase and holding
of an  ERISA-Restricted  Certificate by a Plan or a Person that is purchasing or
holding  such a  Certificate  with the assets of a Plan will not  constitute  or
result in a prohibited  transaction under ERISA or Section 4975 of the Code. The
preparation and delivery of the certificate and opinions referred to above shall
not  be  an  expense  of  the  Trust  Fund,   the  Trustee  or  the   Depositor.
Notwithstanding  the foregoing,  no opinion or certificate shall be required for
the initial issuance of the ERISA-Restricted Certificates.

     (e) As a  condition  of the  registration  of  transfer  or exchange of any
Certificate,  the  Certificate  Registrar  may  require the  certified  taxpayer
identification  number of the owner of the  Certificate and the payment of a sum
sufficient to cover any tax or other  governmental  charge imposed in connection
therewith;  provided,  however,  that the  Certificate  Registrar  shall have no
obligation  to require such payment or to determine  whether or not any such tax
or  charge  may  be  applicable.   No  service  charge  shall  be  made  to  the
Certificateholder for any registration, transfer or exchange of Certificate. (f)
Notwithstanding   anything  to  the  contrary   contained  herein,  no  Residual
Certificate may be owned, pledged or transferred,  directly or indirectly, by or
to a Disqualified Organization.

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

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

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

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

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

     Section 3.06.  Persons Deemed Owners.  Subject to the provisions of Section
3.09 with respect to Book-Entry  Certificates,  the Depositor,  the 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 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 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. 

          (v) the Trustee shall not be required to monitor, determine or inquire
     as to  compliance  with  any  transfer  restrictions  with  respect  to the
     Book-Entry  Certificates,  and the  Trustee  shall  have no  liability  for
     transfers of Book-Entry Certificates made through the book-entry facilities
     of  the  Clearing  Agency,   made  in  violation  of  applicable   transfer
     restriction.  

     (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  Depositor 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.

     (b) Upon the reasonable  advance written  request of any  Certificateholder
that is a savings and loan, bank or insurance company, the Trustee shall, to the
extent that such  information  has been provided to the Trustee by the Servicer,
provide,  or cause to be provided,  to such  Certificateholder  such reports and

     (c) Within 90 days, or such shorter period as may be required by statute or

Person  who at any time  during the  calendar  year was a  Certificateholder  of
record,  and make  available to  Certificate  Owners  (identified as such by the
Clearing Agency) in accordance with applicable 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.

     (d) Not later than two days following each  Distribution  Date, the Trustee

provided in electronic format to the Trustee by the Servicer.

     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 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 payment to itself and others pursuant to
     any  provision  of  this  Agreement;

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

          (iv) 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,  must 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.

     Section 4.05.  Determination of LIBOR. (a) If the outstanding  Certificates
include  any  LIBOR  Certificates,  then on each  LIBOR  Determination  Date the
Trustee shall  determine  LIBOR on the basis of the offered LIBOR  quotations of
the  Reference  Banks as of 11:00 a.m.  London time on such LIBOR  Determination
Date as follows:

          (i) If on any LIBOR  Determination  Date two or more of the  Reference
     Banks provide such offered  quotations,  LIBOR for the next Accrual  Period
     will be the  arithmetic  mean of such  offered  quotations  (rounding  such
     arithmetic mean if necessary to the nearest five decimal places);

          (ii)  If on any  LIBOR  Determination  Date  only  one or  none of the
     Reference  Banks  provides  such  offered  quotations,  LIBOR  for the next
     Accrual  Period will be whichever is the higher of (x) LIBOR as  determined
     on the previous LIBOR  Determination Date or (y) the Reserve Interest Rate.
     The "Reserve Interest Rate" will be either (A) the rate per annum which the
     Trustee determines to be the arithmetic mean (rounding such arithmetic mean
     if  necessary  to  the  nearest  five  decimal  places)  of  the  one-month
     Eurodollar  lending rates that New York City banks  selected by the Trustee
     are quoting,  on the relevant  LIBOR  Determination  Date, to the principal
     London offices of at least two leading banks in the London interbank market
     or (B) in the event that the Trustee can determine no such arithmetic mean,
     the lowest one-month  Eurodollar  lending rate that the New York City banks
     selected by the Trustee  are  quoting on such LIBOR  Determination  Date to
     leading  European banks; and

          (iii) If on any LIBOR  Determination  Date the Trustee is required but
     is unable to determine the Reserve  Interest Rate in the manner provided in
     paragraph  (ii) above,  LIBOR for the next Accrual  Period will be LIBOR as
     determined on the previous LIBOR Determination Date, or, in the case of the
     first  LIBOR   Determination   Date,   the  Initial  LIBOR  Rate.  

     (b) The establishment of LIBOR by the Trustee and the Trustee's  subsequent
calculation of the  Certificate  Interest Rate or Rates  applicable to the LIBOR
Certificates for the relevant Accrual Period,  in the absence of manifest error,
will be final and binding.  In all cases, the Trustee may  conclusively  rely on
quotations of LIBOR for the  Reference  Banks as such  quotations  appear on the
display  designated  "LIUS01M" on the Bloomberg  Financial  Markets  Commodities
News.

     (c) As used herein, "Reference Banks" shall mean four leading banks engaged
in transactions in Eurodollar deposits in the international  Eurocurrency market
(i) with an  established  place of  business  in  London,  England,  (ii)  whose
quotations  appear on the "Bloomberg Screen LIUS01M Index Page" (as described in
the definition of LIBOR) on the applicable  LIBOR  Determination  Date and (iii)
which have been  designated  as such by the  Trustee and are able and willing to
provide such  quotations to the Trustee on each LIBOR  Determination  Date.  The
Reference  Banks  initially  shall be:  Barclay's  plc, Bank of Tokyo,  National
Westminster  Bank and Trust  Company and Bankers  Trust  Company.  If any of the
initial  Reference  Banks should be removed from the  Bloomberg  Screen  LIUS01M
Index Page or in any other way fail to meet the  qualifications  of a  Reference
Bank,  the Trustee shall use its best efforts to designate  alternate  Reference
Banks.

                                   ARTICLE V.

                    DISTRIBUTIONS TO HOLDERS OF CERTIFICATES

     Section  5.01.   Distributions  Generally.  (a)  Subject  to  Section  7.01
respecting the final distribution on the Certificates, on each Distribution Date
the Trustee or the Paying Agent shall make distributions in accordance with this
Article  V.  Such   distributions   shall  be  made  by  check  mailed  to  each
Certificateholder's  address as it appears on the  Certificate  Register  of the
Certificate  Registrar  (which shall  initially be the Trustee) or, upon written
request  made to the Trustee at least three  Business  Days prior to the related
Distribution  Date  by  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 or at the office of the
New  York  Presenting  Agent.  If  any  payment  required  to  be  made  on  the
Certificates  is to be  made on a day  that is not a  Business  Day,  then  such
payment will be made on the next succeeding Business Day.

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

     Section  5.02.  Distributions  from the  Certificate  Account.  (a) On each
Distribution  Date the  Trustee (or the Paying  Agent on behalf of the  Trustee)
shall withdraw from the Certificate  Account the Total  Distribution  Amount and
shall  distribute  such  amount  to the  Holders  of  record  of each  Class  of
Certificates as specified in this Section.

     (b) On each  Distribution  Date, the Trustee shall  distribute the Interest
Remittance Amount for such date in the following order of priority:

          (i) to the Class A  Certificates  Current  Interest for such Class and
     such  Distribution  Date and any  Carryforward  Interest for such Class and
     such date;

          (ii) to the Class B-1  Certificates,  Current  Interest for such Class
     and such Distribution Date and any Carryforward Interest for such Class and
     such date; 

          (iii) to the Class B-2  Certificates,  Current Interest for such Class
     and such Distribution Date and any Carryforward Interest for such Class and
     such date; 

          (iv) to the Class B-3  Certificates,  Current  Interest for such Class
     and such Distribution Date and any Carryforward Interest for such Class and
     such date;  

          (v) to the Class B-4 Certificates, Current Interest for such Class and
     such  Distribution  Date and any  Carryforward  Interest for such Class and
     such date; 

          (vi) to the Class B-5  Certificates,  Current  Interest for such Class
     and such Distribution Date and any Carryforward Interest for such Class and
     such date; and

          (vii) to the Class B-6  Certificates,  Current Interest for such Class
     and such Distribution Date and any Carryforward Interest for such Class and
     such date.

     (c) On each  Distribution  Date, the Trustee shall distribute the Principal
Distribution Amount for such date as follows:

          (i) On each  Distribution  Date (x) prior to the Stepdown  Date or (y)
     with  respect to which a Trigger  Event has  occurred,  the  Trustee  shall
     distribute the Principal Distribution Amount for such date in the following
     order of priority:

               A. to the  Class A  Certificates,  until  the  Class  Certificate
          Principal Amount of such Class has been reduced to zero;

               B. to the Class  B-1  Certificates,  until the Class  Certificate
          Principal  Amount of such Class has been  reduced  to zero;

          Principal  Amount of such Class has been  reduced  to zero;  

               F. to the Class  B-5  Certificates,  until the Class  Certificate
          Principal Amount of such Class has been reduced to zero; and

               G. to the Class  B-6  Certificates,  until the Class  Certificate
          Principal  Amount of such Class has been reduced to zero. 

          (ii) On each  Distribution  Date (x) on or after the Stepdown Date and
     (y) with  respect to which a Trigger  Event has not  occurred,  the Trustee
     shall  distribute  the Principal  Distribution  Amount for such date in the
     following order of priority:

               A. to the Class A Certificates,  an amount equal to the lesser of
          (A) the Principal  Distribution  Amount for such Distribution Date and
          (B) the Class A Principal Distribution Amount for such date, until the
          Class  Certificate  Principal Amount of such Class has been reduced to
          zero;

               B. to the Class B-1  Certificates,  an amount equal to the lesser
          of (A) the excess of (I) the  Principal  Distribution  Amount for such
          Distribution  Date over  (II) the  amount  distributed  to the Class A
          Certificates  on such date  pursuant  to clause  (1) above and (B) the
          Class B-1 Principal Distribution Amount for such date, until the Class
          Certificate  Principal  Amount of such Class has been reduced to zero;

               C. to the Class B-2  Certificates,  an amount equal to the lesser
          of (A) the excess of (I) the  Principal  Distribution  Amount for such
          Distribution Date over (II) the amount  distributed to the Class A and
          Class B-1  Certificates  on such date  pursuant to clauses (1) and (2)
          above and (B) the Class B-2  Principal  Distribution  Amount  for such
          date, until the Class  Certificate  Principal Amount of such Class has
          been  reduced  to zero;

               D. to the Class B-3  Certificates,  an amount equal to the lesser
          of (A) the excess of (1) the  Principal  Distribution  Amount for such
          Distribution  Date over (II) the  amount  distributed  to the Class A,
          Class B-1 and Class B-2  Certificates on such date pursuant to clauses
          (1)  through  (3) above and (B) the Class B-3  Principal  Distribution
          Amount for such date, until the Class Certificate  Principal Amount of
          such  Class  has  been  reduced  to  zero;  and

               E. to the Class B-4  Certificates,  an amount equal to the lesser
          of (A) the excess of (1) the  Principal  Distribution  Amount for such
          Distribution  Date over (II) the  amount  distributed  to the Class A,
          Class B-1, Class B-2 and Class B-3  Certificates on such date pursuant
          to  clauses  (1)  through  (4) above  and (B) the Class B-4  Principal
          Distribution  Amount  for  such  date,  until  the  Class  Certificate
          Principal Amount of such Class has been reduced to zero; and 

               F. to the Class B-5  Certificates,  an amount equal to the lesser
          of (A) the excess of (1) the  Principal  Distribution  Amount for such
          Distribution  Date over (II) the  amount  distributed  to the Class A,
          Class B-1,  Class B-2,  Class B-3 and Class B-4  Certificates  on such
          date  pursuant  to clauses (1) through (5) above and (B) the Class B-5
          Principal   Distribution   Amount  for  such  date,  until  the  Class
          Certificate  Principal  Amount of such Class has been reduced to zero;
          and

               G. to the Class B-6  Certificates,  an amount equal to the lesser
          of (A) the excess of (1) the  Principal  Distribution  Amount for such
          Distribution  Date over (II) the  amount  distributed  to the Class A,
          Class B-1, Class B-2, Class B-3, Class B-4 and Class B-5  Certificates
          on such date  pursuant  to clauses  (1)  through (6) above and (B) the
          Class B-6 Principal Distribution Amount for such date, until the Class
          Certificate  Principal  Amount of such Class has been reduced to zero;
          and

     Notwithstanding the foregoing,  on any Distribution Date on which the Class
     Certificate  Principal Amount of each Class of Certificates having a higher
     priority of distribution has been reduced to zero, any remaining  Principal
     Distribution  Amount will be distributed to the remaining  Classes of Class
     A, Class  B-1,  Class B-2,  Class B-3,  Class B-4,  Class B-5 and Class B-6
     Certificates,  in the order of priority  set forth  above,  until the Class
     Certificate Principal Amount of each such Class has been reduced to zero.

     (d) On each  Distribution  Date, the Trustee shall distribute to the Holder
of the Class R Certificate  any  remaining  Total  Distribution  Amount for such
Distribution  Date after  application of all amounts described in paragraphs (b)
and (c) of this Section 5.02. Any  distributions  pursuant to this paragraph (d)
shall  not  reduce  the  Class  Certificate  Principal  Amount  of the  Class  R
Certificate.

     Section 5.03.  Allocation of Losses. On each  Distribution  Date, the Class
Certificate  Principal  Amount of each Class of Class B-1, Class B-2, Class B-3,
Class B-4, Class B-5 and Class B-6 Certificates will be reduced by the amount of
any Applied Loss Amount for such date, in the following order of priority:

          (i) to  the  Class  B-6  Certificates,  until  the  Class  Certificate
     Principal Amount thereof has been reduced to zero;

          (ii) to the  Class  B-5  Certificates,  until  the  Class  Certificate
     Principal  Amount thereof has been reduced to zero;  

          (iii) to the Class  B-4  Certificates,  until  the  Class  Certificate
     Principal  Amount  thereof has been reduced to zero;  

          (iv) to the  Class  B-3  Certificates,  until  the  Class  Certificate
     Principal  Amount  thereof has been  reduced to zero;  

          (v) to  the  Class  B-2  Certificates,  until  the  Class  Certificate
     Principal  Amount  thereof has been reduced to zero;  and 

          (vi) to the  Class  B-1  Certificates,  until  the  Class  Certificate
     Principal Amount thereof has been reduced to zero.

     Section 5.04.  Trustee  Advances.  In the event that the Servicer fails for
any  reason  to make an  Advance  required  to be  made  by it  pursuant  to the
applicable  Sale and Servicing  Agreement on or before the Remittance  Date, the
Trustee  shall,  on or before  the  related  Distribution  Date,  deposit in the
Certificate Account an amount equal to the excess of (a) Advances required to be
made by the Servicer that would have been deposited in such Certificate  Account
over (b) the amount of any Advance  made by the  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  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 Servicer.

     Section 5.05.  Distributions of Principal on Redemption  Certificates.  (a)
Except as provided in subclauses (d) and (f) below, on each Distribution Date on
which distributions in reduction of the Class Certificate  Principal Amount of a
Class of Redemption  Certificates are made, such  distributions  will be made in
the following order of priority:

          (i) any request by the personal representative of a Deceased Holder or
     by a surviving tenant by the entirety,  by a surviving joint tenant or by a
     surviving  tenant in common or other  Person  empowered to act on behalf of
     such  Deceased  Holder  upon his or her  death,  in an amount up to but not
     exceeding $100,000 per request; and

          (ii)  any  request  by a Living  Holder,  in an  amount  up to but not
     exceeding $10,000 per request.

     Thereafter,  distributions will be made as provided in clauses (i) and (ii)
above up to a second  $100,000  and  $10,000  per  request,  respectively.  This
sequence  of  priorities  will  be  repeated  for  each  request  for  principal
distributions   made  by  the  Certificate  Owners  of  a  Class  of  Redemption
Certificates until all such requests have been honored.

     Requests  for  distributions  in  reduction  of the  Certificate  Principal
Amounts of Redemption  Certificates  presented on behalf of Deceased  Holders in
accordance with the provisions of clause (i) above will be accepted in the order
of their receipt by the Clearing Agency. Requests for distributions in reduction
of the Certificate  Principal  Amounts of Redemption  Certificates  presented in
accordance  with the  provisions  of clause  (ii) above will be  accepted in the
order of  priority  established  by the random lot  procedures  of the  Clearing
Agency after all requests  with  respect to such Class  presented in  accordance
with clause (i) have been honored.  All requests for  distributions in reduction
of the Class Certificate Principal Amount of a Class of Redemption  Certificates
with respect to any  Distribution  Date shall be made in accordance with Section
4.03(c) below and must be received by the Clearing  Agency and forwarded to, and
received  by, the  Trustee no later than the close of  business  on the  related
Record Date. Requests for distributions that are received by the Clearing Agency
and  forwarded to the Trustee  after the related  Record Date and  requests,  in
either case, for distributions  timely received but not accepted with respect to
any  Distribution  Date,  will be  treated  as  requests  for  distributions  in
reduction of the Class  Certificate  Principal Amount of the applicable Class of
Redemption  Certificates  on the next  succeeding  Distribution  Date,  and each
succeeding Distribution Date thereafter,  until each such request is accepted or
is  withdrawn  as  provided  in Section  5.05(c).  Such  requests  as are not so
withdrawn shall retain their order of priority  without the need for any further
action  on the  part  of  the  appropriate  Certificate  Owner  of  the  related
Redemption  Certificate,  all in accordance  with the procedures of the Clearing
Agency  and the  Trustee.  Upon the  transfer  of  beneficial  ownership  of any
Redemption  Certificate,  any  distribution  request  previously  submitted with
respect to such  Certificate will be deemed to have been withdrawn only upon the
receipt by the Trustee of notification of such withdrawal  using a form required
by the Clearing Agency.

     Distributions  in  reduction  of  the  Certificate   Principal  Amounts  of
Redemption  Certificates will be applied, in the aggregate, to such Certificates
in an  amount  equal  to  the  portion  of  the  Principal  Distribution  Amount
distributable to the Redemption  Certificates  pursuant to Section 5.02(c), plus
any amounts  available for  distribution  from the applicable  Rounding  Account
pursuant  to  Section  5.05(e),  provided  that the  aggregate  distribution  in
reduction of the Class  Certificate  Principal Amount of any Class of Redemption
Certificates on any Distribution Date is made in an integral multiple of $1,000.

     (b) A "Deceased Holder" is a Certificate Owner of a Redemption  Certificate
who was  living at the time such  interest  was  acquired  and whose  authorized
personal  representative,  surviving  tenant by the  entirety,  surviving  joint
tenant or surviving  tenant in common or other Person empowered to act on behalf
of such Certificate  Owner upon his or her death,  causes to be furnished to the
Trustee a certified copy of the death  certificate of such Certificate Owner and
any additional evidence of death required by and satisfactory to the Trustee and
any tax waivers requested by the Trustee.  Redemption Certificates  beneficially
owned by tenants by the  entirety,  joint  tenants or tenants in common  will be
considered to be beneficially  owned by a single owner. The death of a tenant by
the entirety, joint tenant or tenant in common will be deemed to be the death of
the Certificate  Owner,  and any Redemption  Certificates so beneficially  owned
will be eligible for priority with respect to  distributions in reduction of the
Class  Certificate  Principal  Amount of such Class of Redemption  Certificates,
subject to the limitations stated above.  Redemption  Certificates  beneficially
owned by a trust will be considered to be beneficially owned by each beneficiary
of the trust to the extent of such  beneficiary's  beneficial  interest therein,
but in no event  will a  trust's  beneficiaries  collectively  be  deemed  to be
Certificate  Owners of a number of Individual  Redemption  Certificates  greater
than the number of Individual Redemption Certificates of which such trust is the
beneficial owner. The death of a beneficiary of a trust will be deemed to be the
death of a Certificate Owner of the Redemption  Certificates  beneficially owned
by the trust to the extent of such  beneficiary's  beneficial  interest  in such
trust. The death of an individual who was a tenant by the entirety, joint tenant
or tenant in common in a  tenancy  that is the  beneficiary  of a trust  will be
deemed to be the death of the  beneficiary  of the trust.  The death of a person
who,  during his or her  lifetime,  was  entitled  to  substantially  all of the
beneficial  ownership interests in Redemption  Certificates will be deemed to be
the death of the Certificate Owner of such Redemption Certificates regardless of
the  registration  of  ownership  of  such  Redemption  Certificates,   if  such
beneficial interest can be established to the satisfaction of the Trustee.  Such
beneficial  interest  will be deemed to exist in typical cases of street name or
nominee ownership,  ownership by a trustee, ownership under the Uniform Gifts to
Minors Act and community property or other joint ownership  arrangements between
a husband  and  wife.  Beneficial  interests  shall  include  the power to sell,
transfer  or  otherwise  dispose of a  Redemption  Certificate  and the right to
receive  the  proceeds  therefrom,  as well as  interest  and  distributions  in
reduction of the Certificate  Principal  Amounts of the Redemption  Certificates
payable  with  respect  thereto.  The  Trustee  shall  not be under  any duty to
determine  independently the occurrence of the death of any deceased Certificate
Owner. The Trustee may rely entirely upon documentation delivered to it pursuant
to Section 5.05(a) in establishing  the eligibility of any Certificate  Owner to
receive the priority accorded Deceased Holders in Section 5.05(a).

     (c) Requests for  distributions  in reduction of the Certificate  Principal
Amount of a Redemption  Certificate must be made by delivering a written request
therefor to the  Clearing  Agency  Participant  or Financial  Intermediary  that
maintains  the  account  evidencing  the  Certificate  Owner's  interest in such
Redemption   Certificate.   Such  Clearing   Agency   Participant  or  Financial
Intermediary  should in turn make the request of the Clearing Agency (or, in the
case of an Financial Intermediary, such Financial Intermediary should notify the
related  Clearing  Agency  Participant of such request,  which  Clearing  Agency
Participant  should make the request of the Clearing  Agency) on a form required
by the Clearing  Agency and provided to the Clearing  Agency  Participant.  Upon
receipt  of such  request,  the  Clearing  Agency  will date and time stamp such
request  and  forward  such  request to the  Trustee.  The  Clearing  Agency may
establish such  procedures as it deems fair and equitable to establish the order
of receipt of requests  for such  distributions  received by it on the same day.
The  Trustee  shall not be liable  for any delay in  delivery  of  requests  for
distributions or withdrawals of such requests by the Clearing Agency, a Clearing
Agency Participant or any Financial Intermediary.

     In the event  that any  requests  for  distributions  in  reduction  of the
Certificate  Principal  Amount of  Redemption  Certificates  are rejected by the
Trustee for failure to comply with the  requirements  of this Section 5.05,  the
Trustee  shall  return  such  requests  to  the   appropriate   Clearing  Agency
Participant  with a copy to the Clearing  Agency with an  explanation  as to the
reason for such rejection.

     The Trustee shall  maintain a list of those  Clearing  Agency  Participants
representing  the  Certificate  Owners  of  Redemption  Certificates  that  have
submitted  requests for distributions in reduction of the Certificate  Principal
Amount of such Redemption  Certificates,  together with the order of receipt and
the amounts of such requests.  The Trustee shall notify the Clearing  Agency and
the  appropriate  Clearing  Agency  Participants  as to which requests should be
honored on each  Distribution  Date.  Requests  shall be honored by the Clearing
Agency in accordance  with the  procedures,  and subject to the  priorities  and
limitations, described in this Section 5.05. The exact procedures to be followed
by the  Trustee  and the  Clearing  Agency  for  purposes  of  determining  such
priorities and limitations  shall be those  established from time to time by the
Trustee or the Clearing Agency, as the case may be. The decisions of the Trustee
and the Clearing  Agency  concerning  such matters shall be final and binding on
all affected Persons.

     Payments in reduction of the  Certificate  Principal  Amounts of Redemption
Certificates  shall  be  made  on  the  applicable  Distribution  Date  and  the
Certificate  Balances  as to which such  payments  are made shall  cease to bear
interest  after the last day of the  month  preceding  the  month in which  such
Distribution Date occurs.

     Any  Certificate  Owner of a Redemption  Certificate  that has  requested a
distribution  may  withdraw  its request by so notifying in writing the Clearing
Agency  Participant or Financial  Intermediary  that maintains such  Certificate
Owner's  account.  In the event that such account is  maintained  by a Financial
Intermediary,  such Financial  Intermediary  should notify the related  Clearing
Agency  Participant which in turn should forward the withdrawal of such request,
on a form  required by the Clearing  Agency,  to the Trustee.  If such notice of
withdrawal of a request for  distribution  has not been received by the Clearing
Agency and  forwarded  to the  Trustee on or before the Record Date for the next
Distribution  Date,  the  previously  made  request  for  distribution  will  be
irrevocable  with  respect to the making of  distributions  in  reduction of the
Certificate Principal Amount of such Redemption Certificate on such Distribution
Date.

     (d) To the extent,  if any,  that amounts  available  for  distribution  in
reduction of the Class  Certificate  Principal Amount of any Class of Redemption
Certificates  on a  Distribution  Date exceed the dollar  amount of requests for
distributions  with respect to such Class that have been received by the related
Record Date, as provided in Section 5.05(c) above, distributions in reduction of
the Class Certificate Principal Amount of such Class of Redemption  Certificates
will be made by mandatory  distributions in reduction thereof. The Trustee shall
notify the Clearing Agency of the aggregate amount of the mandatory distribution
in  reduction  of the  Class  Certificate  Principal  Amount  of such  Class  of
Redemption  Certificates to be made on the next Distribution  Date. The Clearing
Agency shall then  allocate  such  aggregate  amount  among its Clearing  Agency
Participants  on a random lot basis.  Each Clearing Agency  Participant  and, in
turn, each Financial Intermediary,  will then select, in accordance with its own
procedures,  Individual  Redemption  Certificates  from among  those held in its
accounts  to  receive   mandatory   distributions  in  reduction  of  the  Class
Certificate Principal Amount of such Class of Redemption Certificates, such that
the total amount so selected is equal to the aggregate  amount of such mandatory
distributions  allocated to such  Clearing  Agency  Participant  by the Clearing
Agency  and to  such  Financial  Intermediary  by its  related  Clearing  Agency
Participant,  as the case may be.  Clearing  Agency  Participants  and Financial
Intermediaries  that  hold  Redemption   Certificates   selected  for  mandatory
distributions  in reduction of the Class  Certificate  Principal  Amount thereof
should  provide  notice  of  such  mandatory   distributions   to  the  affected
Certificate Owners.

     (e) On the Closing Date, a Rounding  Account shall be established  with the
Trustee for each Class of  Redemption  Certificates,  and Lehman  Brothers  Inc.
shall  cause to be  initially  deposited  the sum of  $999.99  in each  Rounding
Account.  On each Distribution Date on which a distribution is made in reduction
of the Class Certificate Principal Amount of a Class of Redemption Certificates,
funds on  deposit in the  applicable  Rounding  Account  shall be, to the extent
needed,  withdrawn  by the Trustee  and  applied to round  upward to an integral
multiple  of  $1,000  the  aggregate  distribution  in  reduction  of the  Class
Certificate  Principal  Amount  to be  made  on  such  Redemption  Certificates.
Rounding  of  such  distribution  on  such  Redemption   Certificates  shall  be
accomplished,  on the first such  Distribution  Date,  by  withdrawing  from the
applicable  Rounding  Account the amount of funds,  if any,  needed to round the
amount  otherwise  available  for such  distribution  in  reduction of the Class
Certificate Principal Amount of such Class of Redemption  Certificates upward to
the next integral  multiple of $1,000.  On each succeeding  Distribution Date on
which  distributions in reduction of the Class  Certificate  Principal Amount of
such Class of Redemption  Certificates  are to be made, the aggregate  amount of
such distributions  allocable to such Class of Redemption  Certificates shall be
applied first to repay any funds withdrawn from the applicable  Rounding Account
and not previously  repaid,  and then the remainder of such allocable amount, if
any, shall be similarly rounded upward and applied as distributions in reduction
of  the  Class  Certificate   Principal  Amount  of  such  Class  of  Redemption
Certificates; this process shall continue on succeeding Distribution Dates until
the Class Certificate Principal Amount of such Class of Redemption  Certificates
has been reduced to zero.  Each Rounding  Account  shall be an "outside  reserve
fund"  under the REMIC  Provisions  that is  beneficially  owned for all federal
income tax purposes by Lehman Brothers Inc. Lehman Brothers Inc. will report all
income,  gain,  deduction  or loss  with  respect  thereto.  The  Trustee  shall
distribute interest earnings, if any, on amounts held in any Rounding Account as
such interest is earned  pursuant to written  instructions  from Lehman Brothers
Inc. to the Trustee.

     Notwithstanding  anything herein to the contrary,  on the Distribution Date
on which distributions in reduction of the Class Certificate Principal Amount of
any Class of Redemption Certificates will reduce the Class Certificate Principal
Amount  thereof to zero or in the event that  distributions  in reduction of the
Class Certificate Principal Amount of such Class of Redemption  Certificates are
made in accordance with the provisions set forth in Section  5.05(f),  an amount
equal to the difference  between $999.99 and the sum then held in the applicable
Rounding Account shall be paid from the Principal  Distribution  Amount for such
Distribution  Date to such Rounding  Account.  Any funds then on deposit in such
Rounding Account shall be distributed to Lehman Brothers Inc.

     (f)  Notwithstanding  any  provisions  herein  to  the  contrary,  on  each
Distribution  Date following the first  Distribution Date on or after the Credit
Support  Depletion Date, all distributions in reduction of the Class Certificate
Principal Amount of any Class of Redemption  Certificates will be made among the
Holders  of such Class of  Certificates,  pro rata,  based on their  Certificate
Principal  Amounts,  and will not be made in  integral  multiples  of  $1,000 or
pursuant to requested distributions or mandatory distributions by random lot.

     (g) In the event that  Definitive  Certificates  representing  any Class of
Redemption Certificates are issued pursuant to Section 3.09(c), all requests for
distributions  or  withdrawals  of such requests  relating to such Class must be
submitted to the Trustee,  and the Trustee shall perform the functions described
in Section 5.05(a) through (c) using its own procedures, which procedures shall,
to the extent  practicable,  be  consistent  with the  procedures  described  in
Section 5.05(a) through (c).

                                   ARTICLE VI.

duty of the Trustee.  If an Event of Default has occurred and has not  otherwise
been cured or waived,  the Trustee shall  exercise such of the rights and powers
vested  in it by this  Agreement  and use the same  degree  of care and skill in
their exercise as a prudent Person would exercise or use under the circumstances
in the  conduct of such  Person's  own  affairs  unless the Trustee is acting as
Servicer,  in which  case it shall use the same  degree of care and skill as the
Servicer under the applicable Sale and Servicing Agreement.

     (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 Servicer, to the Trustee pursuant to this Agreement.

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

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

          (ii) For all purposes under this  Agreement,  the Trustee shall not be
     deemed to have notice of any Event of Default  (other than resulting from a
     failure by the Servicer (i) to remit funds (or to make Advances) or (ii) to
     furnish information to the Trustee when required to do so by the applicable
     Sale and Servicing  Agreement) 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 

          (iv) The Trustee shall not be  responsible  for any act or omission of
     the  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  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.

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

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

          (ii) The  Trustee  may  consult  with  counsel  and any  advice of its
     counsel or Opinion of Counsel shall be full and complete  authorization and
     protection  in  respect of any action  taken or  suffered  or omitted by it
     hereunder  in good faith and in  accordance  with such advice or Opinion of
     Counsel;  (iii) The Trustee shall not be  personally  liable for any action
     taken,  suffered or omitted by it in good faith and reasonably  believed by
     it to be authorized or within the discretion or rights or powers  conferred
     upon it by this  Agreement;  (iv)  Unless an Event of  Default  shall  have
     occurred  and be  continuing,  the  Trustee  shall not be bound to make any
     investigation   into  the  facts  or  matters  stated  in  any  resolution,
     certificate,  statement,  instrument,  opinion,  report,  notice,  request,
     consent,  order,  approval,  bond or other paper or document  (provided the
     same appears regular on its face),  unless requested in writing to do so by
     Holders of at least a majority in Class  Certificate  Principal  Amount (or
     Percentage  Interest)  of each Class of  Certificates;  provided,  however,
     that, if the payment within a reasonable  time to the Trustee of the costs,
     expenses or  liabilities  likely to be incurred by it in the making of such
     investigation is, in the opinion of the Trustee,  not reasonably assured to
     the Trustee by the security  afforded to it by the terms of this Agreement,
     the  Trustee may  require  reasonable  indemnity  against  such  expense or
     liability  or  payment  of  such  estimated  expenses  as  a  condition  to
     proceeding.  The  reasonable  expense  thereof shall be paid by the Holders
     requesting such  investigation;  and (v) The Trustee may execute any of the
     trusts or powers  hereunder or perform any duties hereunder either directly
     or by or through agents or attorneys,  which agents or attorneys shall have
     any or all of the rights,  powers,  duties and  obligations  of the Trustee
     conferred  on them by such  appointment  provided  that the  Trustee  shall
     continue  to be  responsible  for its  duties  and  obligations  hereunder.
     Section 6. The  Trustee  makes no  representations  as to the  validity  or
     sufficiency  of this  Agreement  or of the  Certificates  (other  than  the
     certificate of authentication on the Certificates) or of any Mortgage Loan,
     or related  document save that the Trustee  represents  that,  assuming due
     execution and delivery by the other parties hereto, this Agreement has been
     duly authorized, executed and delivered by it and constitutes its valid and
     binding  obligation,  enforceable  against it in accordance  with its terms
     except that such enforceability may be subject to (A) applicable bankruptcy
     and insolvency laws and other similar laws affecting the enforcement of the
     rights  of  creditors  generally,  and (B)  general  principles  of  equity
     regardless  of whether such  enforcement  is  considered in a proceeding in
     equity  or at law.  The  Trustee  shall not be  accountable  for the use or
     application   by  the   Depositor  of  funds  paid  to  the   Depositor  in
     consideration  of the assignment of the Mortgage Loans to the Trust Fund by
     the Depositor or for the use or application of any funds deposited into the
     Certificate Account or any other fund or account maintained with respect to
     the Certificates.

     Section  6.03.  Trustee  Not Liable for  Certificates.  The Trustee and any
Affiliate or agent of the Trustee in its  individual  or any other  capacity may
become the owner or pledgee of Certificates  and may transact  banking and trust
with the other parties  hereto with the same rights it would have if it were not
Trustee or such agent.

     Section 6.04. Trustee May Own Certificates.  The Trustee hereunder shall at
all times be (i) an  institution  insured by the FDIC and (ii) a corporation  or
national banking association, organized and doing business under the laws of any

corporate trust powers,  having a combined  capital and surplus of not less than
$50,000,000  and  subject  to  supervision  or  examination  by federal or state
authority. If such corporation or national banking association publishes reports
of condition at least  annually,  pursuant to law or to the  requirements of the
aforesaid  supervising  or examining  authority,  then, for the purposes of this
Section,  the  combined  capital  and  surplus of such  corporation  or national
banking  association  shall be deemed to be its combined  capital and surplus as
set forth in its most recent  report of condition so  published.  In case at any
time the Trustee  shall cease to be eligible in  accordance  with  provisions of
this Section,  the Trustee shall resign  immediately  in the manner and with the
effect specified in Section 6.06.

     Section 6.05. Eligibility  Requirements for Trustee. (a) The Trustee may at
any time  resign  and be  discharged  from the trust  hereby  created  by giving
written  notice  thereof  to  the  Depositor.  Upon  receiving  such  notice  of
resignation,  the Depositor will promptly appoint a successor trustee by written
instrument,  one copy of which  instrument  shall be delivered to the  resigning
Trustee,  and one copy to the successor  trustee.  If no successor trustee shall
have been so appointed and shall have accepted  appointment within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor trustee.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

     Section 6.11.  Indemnification  of Trustee.  The Trustee and its directors,
officers,  employees  and agents shall be entitled to  indemnification  from the
Trust Fund, to the extent that  indemnification  is not provided by the Servicer
pursuant to either Sale and  Servicing  Agreement,  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, (a) 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 or under the Mortgage Loan Sale and  Assignment  Agreement,  either of
the  Sale and  Servicing  Agreements  or the  Custodial  Agreement,  and (b) the
selection by the  Depositor of the  Custodian,  the failure of the  Custodian to
perform  in its  obligations  under  the  Custodial  Agreement  or  the  willful
misconduct of the Custodian thereunder, provided that:

          (i) to the extent that the  indemnification  provisions of either Sale
     and  Servicing   Agreement  indemnify  the  Trustee,  as  assignee  of  the
     "Purchaser"  thereunder,  for such loss,  liability or expense, the Trustee
     has first made reasonable  efforts to enforce any applicable  provisions in
     such Sale and Servicing  Agreement for  indemnification or reimbursement of
     the Trustee (as  "Purchaser")  by the  Servicer  (it being  understood  and
     agreed that "reasonable efforts" shall, without limitation, (A) not require
     that the Trustee  have  brought  suit  against the Servicer to enforce such
     indemnification  provisions before making a claim against the assets of the
     Trust  Fund and (B) have been  satisfied  if the  Trustee  shall  have made
     demand on the Servicer for such indemnification, but the Servicer is unable
     to satisfy such demand due to its insolvency);

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

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

          (iv)  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  receive,  and is  authorized  to pay to itself  the amount of income or gain
earned from the  investment  of funds in the  Certificate  Account.  The Trustee
shall be entitled to reimbursement of reasonable disbursements and expenses made
or incurred by the Trustee in accordance  with the provisions of this Agreement,
the  Mortgage  Loan Sale and  Assignment  Agreement,  either Sale and  Servicing
Agreement  or the  Custodial  Agreement,  but  not for  (i)  any  such  expense,
disbursement  or advance as may arise from the  Trustee's  negligence or willful
misconduct or (ii) any amount expressly required under this Agreement to be paid
by the Trustee from its own funds.

     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 Servicer, the
Trustee  shall  request the  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. Trustee To Act; Appointment of Successor.  (a) If an Event of
Default under either Sale and Servicing Agreement 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 such Sale
and Servicing  Agreement,  the Trustee by notice in writing to the Servicer may,
and shall, if so directed by Certificateholders  evidencing more than 50% of the
Class  Certificate  Principal  Amount (or Percentage  Interest) of each Class of
Certificates  affected  thereby,  terminate all of the rights and obligations of
the Servicer under both Sale and Servicing Agreements and in and to the Mortgage
Loans and the proceeds thereof.  On or after the receipt by the Servicer of such
written  notice,  all  authority  and  power  of the  Servicer,  and only in its
capacity as  Servicer  under each Sale and  Servicing  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 each Sale and  Servicing  Agreement;
and the Trustee is hereby  authorized  and empowered to execute and deliver,  on
behalf of the defaulting 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.

     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 Servicer  upon such  Servicer's
failure to remit funds on the Remittance Date.

     (b) On and after the time the  Servicer  receives  a notice of  termination
from the  Trustee  pursuant  to Section  6.14(a)  or the  Trustee  receives  the
resignation of the Servicer  evidenced by an Opinion of Counsel  pursuant to the
applicable provisions of the Sale and Servicing Agreements,  the Trustee, unless
another  servicer  shall  have been  appointed,  shall be the  successor  in all
respects to the  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 Servicer under each Sale
and Servicing  Agreement,  including the obligation to make Advances;  provided,
however,  that any failure to perform such duties or responsibilities  caused by
the Servicer's  failure to provide  information  required by the applicable Sale
and  Servicing  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 Servicer prior to the issuance of any notice of termination.  In
the  Trustee's  capacity  as such  successor,  the  Trustee  shall have the same
limitations  on  liability  herein  granted  to the  Servicer.  As  compensation
therefor,  the Trustee shall be entitled to receive all compensation  payable to
the Servicer under each Sale and Servicing  Agreement,  including the applicable
portion of the related 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 single established housing and
home  finance  institution  servicer,  master  servicer,  servicer  or  mortgage
servicing  institution  having  a net  worth of not less  than  $15,000,000  and
meeting such other  standards  for a successor  servicer as are set forth in the
Sale and Servicing Agreements, as the successor to such Servicer under both Sale
and  Servicing  Agreements  in the  assumption  of all of the  responsibilities,
duties or liabilities of a servicer, like the Servicer. Any entity designated by
the  Trustee  as a  successor  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  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  Servicer.  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 Servicer shall
cooperate  with  the  Trustee  and  any  successor  servicer  in  effecting  the
termination of the Servicer's  responsibilities  and rights hereunder including,
without  limitation,  notifying  Mortgagors  of the  assignment of the servicing
functions and providing the Trustee and successor servicer,  as applicable,  all
documents and records in electronic or other form reasonably  requested by it to
enable it to assume the Servicer's  functions  hereunder and the transfer to the
Trustee or such successor  servicer,  as applicable,  all amounts which shall at
the time be or should have been  deposited  by the  Servicer in the  Certificate
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  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
Servicer to deliver, or any delay in delivering,  cash,  documents or records to
it,  (ii)  to  cooperate  as  required  by the  applicable  Sale  and  Servicing
Agreement, (iii) to deliver the Mortgage Loan data to the Trustee as required by
the applicable Sale and Servicing Agreement or (iv) restrictions  imposed by any
regulatory  authority having  jurisdiction over the 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
Servicer in the performance of its  obligations  under either Sale and Servicing
Agreement  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,  any Event of
Default  arising  therefrom  shall be  deemed to have  been  remedied  for every
purpose of this  Agreement,  and, to the extent that such default related to the
Servicer's obligation to make any Advance, the Trustee shall not be obligated to
make such Advance,  notwithstanding  anything to the contrary in 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 Servicer or
appointment  of a  successor  Servicer,  in each case as  provided  herein,  the
Trustee  shall  promptly  mail  notice  thereof  by  first  class  mail  to  the
Certificateholders  at their respective  addresses  appearing on the Certificate
Register.  The Trustee  shall also,  within 45 days after the  occurrence of any
Event  of  Default  known  to  the  Trustee,  give  written  notice  thereof  to
Certificateholders, unless such Event of Default shall have been cured or waived
prior to the issuance of such notice and within such 45-day period.

     Section 6.18. Directions by Certificateholders and Duties of Trustee During
Event of Default.  Subject to the provisions of Section 8.01 hereof,  during the
continuance of any Event of Default, Holders of Certificates evidencing not less
than 25% of the Class Certificate  Principal Amount (or Percentage  Interest) of
each Class of  Certificates  affected  thereby  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 Servicer or any successor servicer from its rights and duties
as  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 Servicer and Upon Event
of Default.  In the event that the Trustee  shall have actual  knowledge  of any
action or inaction of the  Servicer  that would  become an Event of Default upon
the Servicer's  failure to remedy the same after notice,  the Trustee shall give
notice  thereof to the  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  Servicer  or any
other Event of Default unless notified  thereof in writing by the Servicer or by
a Certificateholder.

                                  ARTICLE VII.

                            PURCHASE AND TERMINATION
                                OF THE TRUST FUND

     Section 7.01.  Termination of Trust Fund Upon  Repurchase or Liquidation of
All Mortgage  Loans.  (a) The obligations  and  responsibilities  of the Trustee
created  hereby  (other than the  obligation  of the Trustee to make payments to
Certificateholders as set forth in Section 7.02), 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  Loan  Balance  is less than 5% of the  Cut-off  Date  Aggregate  Loan
Balance,  the  Depositor  may cause the Trust  Fund to adopt a plan of  complete
liquidation  pursuant to Section  7.03(a)(i) hereof to sell all of its property.
The  property  of the  Trust  Fund  shall be sold at a price  (the  "Termination
Price") equal to: (i) 100% of the unpaid principal balance of each Mortgage Loan
on the day of such  purchase  plus interest  accrued  thereon at the  applicable
Mortgage  Rate  with  respect  to any  Mortgage  Loan  to the  Due  Date  in the
Collection  Period  immediately  preceding the related  Distribution Date to the
date of such  repurchase  and (ii) the fair market value of any REO Property and
any other property held by any REMIC, such fair market value to be determined by
an appraiser or appraisers mutually agreed upon by the Servicer and the Trustee.

     Section 7.02.  Procedure Upon  Termination of Trust Fund. (a) Notice of any
termination  pursuant  to  the  provisions  of  Section  7.01,   specifying  the
Distribution  Date upon  which the final  distribution  shall be made,  shall be
given promptly by the Trustee by first class mail to  Certificateholders  mailed
no later than the later of 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 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  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 the Collection  Account it maintains,  the  Certificate
Account  and  any  other  account  or  fund   maintained  with  respect  to  the
Certificates,  subject to the Trustee's obligation hereunder to hold all amounts
payable to Certificateholders in trust without interest pending such payment.

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

     Section 7.03. Additional Trust Fund Termination Requirements. (a) The Trust
Fund  shall  be  terminated  in   accordance   with  the  following   additional
requirements, unless the Trustee seeks, and subsequently receives, an Opinion of
Counsel,  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  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,  after  payment of, or
     provision for any outstanding  expenses,  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  operation  and  management  of the Trust  Fund,  or the
obligations  of the parties  hereto,  nor shall  anything  herein set forth,  or
contained in the terms of the Certificates, be construed so as to constitute the
Certificateholders  from time to time as partners or members of an  association,
nor shall any  Certificateholder  be under any  liability to any third person by
reason of any action  taken by the  parties to this  Agreement  pursuant  to any
provision hereof.

     (b)  No   Certificateholder,   solely   by   virtue   of  its   status   as
Certificateholder,  shall  have  any  right  by  virtue  or by  availing  of any
provision of this  Agreement  to institute  any suit,  action or  proceeding  in
equity or at law upon or under or with  respect to this  Agreement,  unless such
Holder  previously  shall have given to the Trustee a written notice of an Event
of Default and of the continuance thereof, as hereinbefore  provided, and unless
also the  Holders  of  Certificates  evidencing  not less  than 25% of the Class
Certificate  Principal  Amount (or Percentage  Interest) of Certificates of each
Class  affected  thereby  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
Certificate   Registrar  and  the  Trustee  that  neither  the  Depositor,   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.  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, if made in the manner provided in this Section.

     (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  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 in reliance thereon,  whether or not notation
of such action is made upon such Certificate.

                                   ARTICLE IX.

                 ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

     Section 9.01. Trustee To Retain Possession of Certain Documents.  Until all
amounts  distributable in respect of the  Certificates  have been distributed in
full, the Trustee (or its custodian) shall retain possession and custody of each
Mortgage File in accordance with and subject to the terms and conditions of this
Agreement; provided, that documents relating to any Additional Collateral may be
held by a custodian on behalf of the Trustee.

     Section 9.02. 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
the  information  furnished  by the  Servicer  or  calculated  by the Trustee in
accordance with this Agreement  pursuant to instructions given by the Depositor,
and 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 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 disseminate to  Certificateholders  Form 1099s (or
otherwise furnish  information  within the control of the Trustee) to the extent
required by applicable law.

     (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.

     (c) The Depositor will 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 or
regulation,  and will file such reports  electronically  with the Securities and
Exchange  Commission  (the  "SEC").  The  Trustee  will sign each such report on
behalf of the Trust  Fund,  and will  forward a copy of each such  report to the
Depositor  promptly  after such report has been filed with the SEC.  The Trustee
shall use its best efforts to seek to terminate such filing obligation  promptly
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.


     Section 9.03.  Release of Mortgage  Files.  (a) Upon becoming  aware of the
payment in full of any  Mortgage  Loan,  or upon  receipt by the  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  Servicer  will  immediately  notify the  Trustee  (or its  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  Certificate  Account  maintained  by the Trustee  pursuant to
Section 4.04 have been or will be so deposited) of a Servicing Officer and shall
request the Trustee (or its  custodian)  to deliver to the  Servicer the related
Mortgage File. Upon receipt of such  certification and request,  the Trustee (or
its custodian)  shall promptly release the related Mortgage File to the Servicer
and the  Trustee  shall  have no  further  responsibility  with  regard  to such
Mortgage  File.  Upon any such  payment  in full,  the  Trustee  authorizes  the
Servicer 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 Certificate 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,  the
Trustee (or its custodian) shall execute such documents as shall be prepared and
furnished to the Trustee by the Servicer (in form  reasonably  acceptable to the
Trustee) and as are necessary to the  prosecution of any such  proceedings.  The
Trustee (or its custodian)  shall,  upon request of the Servicer and delivery to
the Trustee (or its 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 Servicer.  Such trust receipt shall obligate
the Servicer to return the Mortgage File to the Trustee (or its custodian)  when
the need  therefor by the 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 specified  above, the trust receipt shall be released by
the Trustee (or its custodian) to the Servicer.

     (c) The Trustee  covenants and agrees that it will comply with all relevant
laws and regulations governing the custody, processing,  release and delivery of
the Mortgage Loan documents within its possession or control.

                                   ARTICLE X.

                              REMIC ADMINISTRATION

     Section 10.01.  REMIC  Administration.  (a) An election will be made by the
Trustee  on behalf of the  REMIC 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,  the  Certificates  other  than  the  Class  R  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).

     (d) The Trustee shall act as Tax Matters Person for such REMIC. 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 such 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 and the  Holders of  Certificates  shall take any action or
cause such 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 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 has 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 or its  designee,  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  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  Certificate  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 such 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 to the extent  permitted by the  applicable  Sale and
Servicing  Agreement.

     (j) The  Trustee  shall not enter into any  arrangement  by which any REMIC
will receive a fee or other  compensation  for services.  

     Section  10.02.  Prohibited   Transactions  and  Activities.   Neither  the
Depositor 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
such  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) affec`t adversely the status of such REMIC as a REMIC
or of the interests therein 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.

     The Trustee shall not consent to any  modification  of any material term of
any Mortgage  Loan unless (i) such  Mortgage  Loan is in default or the Servicer
certifies that default  thereunder is, in its,  judgment  imminent,  or (ii) the
Trustee  has  received  an  Opinion  of  Counsel  (at the  expense  of the party
requesting such  modification)  to the effect that such  modification  would not
cause the Trust Fund to fail to  qualify as a REMIC or result in the  imposition
of any tax under Section 860(F)(a) or Section 860(G)(d) of the Code.

     Section  10.03.  Indemnification  with Respect to Certain Taxes and Loss of
REMIC Status. In the event that any 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 related  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 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).

                                  ARTICLE XI.

                            MISCELLANEOUS PROVISIONS

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

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

     Section  11.03.  Amendment.  (a) This Agreement may be amended from time to
time by the Depositor 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
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 any 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  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) 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.  

     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 Percentage Interest),  Certificates owned by the Depositor,
the Trustee or the Servicer or Affiliates  thereof are not to be counted so long
as such Certificates are owned by the Depositor,  the Trustee or the Servicer or
Affiliates thereof.

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

covenants,  agreements,  provisions or terms of this Agreement  shall be for any
reason whatsoever held invalid, then such covenants,  agreements,  provisions or

     Section 11.09.  Indulgences;  No Waivers. Neither the failure nor any delay
on the part of a party to exercise any right,  remedy,  power or privilege under

further exercise of the same or of any other right,  remedy, power or privilege,
nor shall any waiver of any right,  remedy,  power or privilege  with respect to

believe  that the  Transferee  has the  intention  to impede the  assessment  or

Dear Sirs:

     In connection with our proposed  purchase of  $_________________  principal
amount of Mortgage  Pass-Through  Certificates,  Series  1998-5 (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 April 1,  1998  between  the  Depositor  and  Norwest  Bank
         Minnesota,  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.

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

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

                                              Very truly yours,

                                              ----------------------------------

                              --------------------

     WHEREAS,  pursuant to each of the Amended and Restated Sale, Warranties and
Servicing  Agreements,  each  dated as of  April  1,  1998  (each,  a "Sale  and
Servicing Agreement"),  between Lehman Capital and Boston Safe Deposit and Trust
Company ("The Boston Company"),  The Boston Company sold to Lehman Capital,  and
Lehman  Capital  purchased  from The  Boston  Company,  certain  mortgage  loans
identified  on the Mortgage  Loan  Schedule  attached  hereto as Schedule A (the
"Mortgage Loans"),  and The Boston Company agreed to service such Mortgage Loans
according to the provisions thereof;

     WHEREAS, pursuant to each Sale and Servicing Agreement, the parties thereto
agreed that, following the execution of such agreement, Lehman Capital would (i)
sell the Mortgage Loans to the Depositor,  and (ii) assign all of its rights and
interest  under each Sale and Servicing  Agreement  (other than its rights under
Section 11.12 of each Sale and Servicing Agreement thereof), and delegate all of
its  obligations  thereunder,  to the Depositor,  as if the Depositor had been a
party to each Sale and Servicing Agreement;

     WHEREAS,  Lehman Capital and the Depositor  acknowledge  and agree that the
Depositor  will  assign all of its rights and  delegate  all of its  obligations
hereunder to the Trustee,  and that each  reference  herein to the  Depositor is

     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
over, deposit with and otherwise convey to the Depositor,  without recourse, all
the right,  title and interest of Lehman  Capital in and to the  Mortgage  Loans
identified on Schedule A hereto, having an aggregate principal balance as of the
Cut-off Date of $216,566,808.48.  Such conveyance includes,  without limitation,
the right to all  distributions  of principal  and interest  received on or with
respect to the Mortgage Loans on and after April 1, 1998 (other than payments of
principal  and interest due on or before such date),  and all such  payments due
after such date but  received  prior to such date and  intended  by the  related
Mortgagors to be applied after such date,  together with all of 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  Insurance  Policies
related to the Mortgage Loans,  and Lehman  Capital's  security  interest in any
collateral  pledged  to secure  the  Mortgage  Loans,  including  the  Mortgaged
Properties, any Additional Collateral and any proceeds of the foregoing.

     Concurrently  with the  execution  and delivery of this  Agreement,  Lehman
Capital  hereby  assigns to the Depositor  all of its rights and interest  under
each Sale and Servicing  Agreement (other than its rights under Section 11.12 of
each Sale and  Servicing  Agreement),  and delegates to the Depositor all of its
obligations  under  each Sale and  Servicing  Agreement.  Concurrently  with the
execution hereof,  the Depositor  tenders the purchase price of  $216,566,808.48
(including accrued  interest).  The Depositor hereby accepts such assignment and
delegation,  and shall be entitled to exercise all such rights of Lehman Capital
under each Sale and Servicing Agreement, as if the Depositor had been a party to
each Sale and Servicing Agreement.

     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
documents or  instruments  with respect to each  Mortgage Loan (each a "Mortgage
File") so  transferred  and assigned,  as specified in the  applicable  Sale and
Servicing 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
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 account  maintained  by the Servicer for such purpose have been
so deposited.

     Section 1.03.  Review of  Documentation.  The  Depositor,  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 U.S. Bank Trust National Association (the "Custodian"),  as custodian for the
Depositor.  The  Custodian is required to review,  within 45 days  following the
Closing  Date,  the Mortgage  File.  If in the course of such review a 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.

     Section 1.04.  Representations and Warranties of Lehman Capital. (a) Lehman
Capital  hereby  represents  and warrants to the  Depositor  that as of the date
hereof that:

          (i) Lehman Capital 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, and to enter into and perform its obligations under this
Agreement;

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

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

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

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

     (b) The  representations  and warranties of The Boston Company with respect
to the related  Mortgage  Loans in the applicable  Sale and Servicing  Agreement
were  made  as of the  date  specified  in the  applicable  Sale  and  Servicing
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
The Boston Company under the applicable Sale and Servicing  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 The Boston  Company 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 or conditions that arise or events that occur subsequent to the date as of
which the  representation  and warranties  with respect to the related  Mortgage
Loans  in the  Sale  and  Servicing  Agreements  were  made,  and  which  do not
constitute a breach of any representation or warranty made by The Boston Company
in Section 3.02 of the applicable Sale and Servicing  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 Boston  Company in Section  3.02 of the
applicable  Sale and Servicing  Agreement,  without regard to whether The Boston
Company 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.  All individual  insurance polices contain a standard  mortgagee
clause naming The Boston  Company and its  successors  and assigns as mortgagee,
and all premiums  thereon have been paid.  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. ss.1.860G-2.

     It is understood  and agreed that the  representations  and  warranties set
forth  herein  survive  delivery of the  Mortgage  Files and the  Assignment  of
Mortgage of each Mortgage Loan to the Depositor. Upon discovery by either Lehman
Capital or the Depositor of a breach of any of the foregoing representations and
warranties  that  adversely  and  materially  affects  the value of the  related
Mortgage Loan, and that does not also constitute a breach of a representation or
warranty of The Boston  Company  under Section 3.02 of the  applicable  Sale and
Servicing Agreement, the party discovering such breach shall give prompt written
notice to the other party.  Within 60 days of the  discovery of any such breach,
Lehman Capital shall either (a) cure such breach in all material  respects,  (b)
repurchase  such Mortgage Loan or any property  acquired in respect thereof from
the Depositor at the applicable Purchase Price or (c) within the two year period
following the Closing Date, substitute a Qualifying Substitute Mortgage Loan for
the affected Mortgage Loan.

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

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

                                  ARTICLE II.

                            MISCELLANEOUS PROVISIONS

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

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

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

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

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

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

     Section  2.05.  Severability  of  Provisions.  If any  one or  more  of the
covenants,  agreements,  provisions or terms of this Agreement  shall be for any
reason whatsoever held invalid, then such covenants,  agreements,  provisions or
terms  shall be  deemed  severable  from the  remaining  covenants,  agreements,
provisions or terms of this Agreement and shall in no way affect the validity or
enforceability of the other provisions of this Agreement.

     Section 2.06. Indulgences; No Waivers. Neither the failure nor any delay on
the part of a party to exercise any right, remedy, power or privilege under this
Agreement  shall  operate as a waiver  thereof,  nor shall any single or partial
exercise of any right,  remedy, power or privilege preclude any other or further
exercise of the same or of any other  right,  remedy,  power or  privilege,  nor
shall any waiver of any right,  remedy,  power or privilege  with respect to any
occurrence  be construed as a waiver of such right,  remedy,  power or privilege
with respect to any other occurrence.  No waiver shall be effective unless it is
in writing and is signed by the party asserted to have granted such waiver.

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

                              AMENDED AND RESTATED
             MORTGAGE LOAN SALE, WARRANTIES AND SERVICING AGREEMENT

     This AMENDED AND RESTATED MORTGAGE LOAN SALE, WARRANTIES AND SERVICING
AGREEMENT (the "Agreement") is executed by and between Lehman Capital, A
Division of Lehman Brothers Holdings Inc., as purchaser (the "Purchaser"), and
Boston Safe Deposit and Trust Company, as seller and servicer (the "Company"),
as of this 1st day of April, 1998. This Amended and Restated Agreement amends
and restates the MORTGAGE LOAN SALE, WARRANTIES AND SERVICING AGREEMENT by and
between the Purchaser and the Company dated as of January 1, 1998 (the
"Original Agreement").

                                  WITNESSETH

     WHEREAS, the Purchaser purchased from the Company and the Company sold to
the Purchaser certain conventional, adjustable rate first-lien mortgage loans
and cooperative loans (hereinafter referred to as "Mortgage Loans") which have
an aggregate outstanding principal balance as of the close of business on the
Cut-off Date, after deduction of payments due on or before such date, of
$104,349,740.96 pursuant to the Original Agreement;

     WHEREAS, each of the Mortgage Loans is secured by a mortgage, deed of
trust or other security instrument creating a first lien on real estate (or
against the shares of a cooperative corporation and the related proprietary
lease) located in the jurisdiction indicated on the Mortgage Loan Schedule,
which is annexed hereto as Exhibit A;

     WHEREAS, the Purchaser and the Company have agreed that the Purchaser
will assign all of its rights and delegate all of its obligations hereunder to
the Depositor (as defined herein), which in turn will assign all of its rights
and delegate all of its obligations (except as otherwise specified herein)
hereunder to the Trustee (as defined herein) under the Trust Agreement (as
defined herein), and that each reference herein to the Purchaser is intended,

          (c) No Conflicts. Neither the execution and delivery of this
Agreement, the origination or acquisition of the Mortgage Loans by the Company,
the sale of the Mortgage Loans to the Purchaser or the other transactions
contemplated hereby, nor the fulfillment of or compliance with the terms and
conditions of this Agreement, will conflict materially with or result in a
material breach of any of the terms, conditions or provisions of the Company's
charter or by-laws or any legal restriction or any agreement or instrument to
which the Company is now a party or by which it is bound, constitute a default
or result in an acceleration under any of the foregoing, or result in any
material violation of any law, rule, regulation, order, judgment or decree to
which the Company or its property is subject, or impair the ability of the
Purchaser to realize on the Mortgage Loans, or impair the value of the Mortgage
Loans;

          (d) Ability to Service. The Company is an approved seller/servicer of
conventional residential mortgage loans for FNMA or FHLMC, with the facilities,
procedures, and experienced personnel necessary for the servicing, in accordance
with Accepted Servicing Practices, of mortgage loans of the same type as the
Mortgage Loans, and is in good standing, to sell mortgage loans to and service
mortgage loans for FNMA or FHLMC, and no event has occurred, including but not
limited to a change in insurance coverage, which would make the Company unable
to comply with FNMA or FHLMC eligibility requirements or which would require
notification to either FNMA or FHLMC;

          (e) Reasonable Servicing Fee. The Company acknowledges and agrees that
the Servicing Fee, as calculated at the Servicing Fee Rate, represents
reasonable compensation for performing such services and that the entire
Servicing Fee shall be treated by the Company, for accounting and tax purposes,
as compensation for the servicing and administration of the Mortgage Loans
pursuant to this Agreement;

          (f) Ability to Perform. The Company does not believe, nor does it have
any reason or cause to believe, that it cannot perform each and every covenant
contained in this Agreement;

          (g) No Litigation Pending. There is no action, suit, proceeding or
investigation pending or threatened against the Company which, either in any one
instance or in the aggregate, may result in any material adverse change in the
business, operations, financial condition, properties or assets of the Company,
or in any material impairment of the right or ability of the Company to carry on
its business substantially as now conducted, or in any material liability on the
part of the Company, or which would draw into question the validity of this
Agreement or the Mortgage Loans or of any action taken or to be taken in
connection with the obligations of the Company contemplated herein, or which
would be likely to impair materially the ability of the Company to perform under
the terms of this Agreement;

          (h) No Consent Required. No consent, approval, authorization or order
of any court or governmental agency or body is required for the execution,
delivery and performance by the Company of or the compliance by the Company with
this Agreement or the sale of the Mortgage Loans as evidenced by the
consummation of the transactions contemplated by this Agreement, or if required,
such approval has been obtained prior to the Closing Date;

          (i) Selection Process. The Mortgage Loans were selected from among the
outstanding adjustable rate one- to four- family mortgage loans in the Company's
portfolio at the Closing Date as to which the representations and warranties set
forth in Section 3.02 could be made and such selection was not made in a manner
so as to affect adversely the interests of the Purchaser;

          (j) No Untrue Information. Neither this Agreement nor any statement,
report or other document furnished or to be furnished pursuant to this Agreement
or in connection with the transactions contemplated hereby contains any
materially untrue statement of fact or omits to state a fact necessary to make
the statements contained therein not misleading;

          (k) [RESERVED];

          (l) Sale Treatment. The Company has determined that the disposition of
the Mortgage Loans pursuant to this Agreement will be afforded sale treatment
for accounting and tax purposes;

          (m) Financial Statements. The Company has delivered to the Purchaser
consolidated financial statements of Mellon Bank Corporation, as to its last two
complete fiscal years and any later quarter ended more than sixty (60) days
prior to the execution of this Agreement. All such financial statements fairly
present the pertinent results of operations and affiliates and have been
prepared in accordance with generally accepted accounting principles constantly
applied throughout the periods involved, except as set forth in the notes
thereto. In addition, the Company has delivered information as to its
conventional mortgage loan delinquency and foreclosure experience for the
immediately preceding three-year period, in each case with respect to mortgage
loans owned by it and such mortgage loans serviced for others during such
period, and all such information so delivered is true and correct in all
material respects. There has been no change in the business, operations,
financial condition, properties or assets of the Company since the date of the
Company's financial statements that would have a material adverse effect on its
ability to perform its obligations under this Agreement. The Company has
completed any forms requested by the Purchaser in a timely manner and in
accordance with the provided instructions;

          (n) No Brokers' Fees. The Company has not dealt with any broker,
investment banker, agent or other person that may be entitled to any commission
or compensation in connection with the sale of the Mortgage Loans; and

          (o) Fair Consideration. The consideration received by the Company upon
the sale of the Mortgage Loans under this Agreement constitutes fair
consideration and reasonably equivalent value for the Mortgage Loans.

     Section 3.02. Representations and Warranties Regarding Individual
Mortgage Loans.

     As to each Mortgage Loan, the Company hereby represents and warrants to
the Purchaser that, as of the Closing Date:

          (a) Mortgage Loans as Described. The information set forth in the
Mortgage Loan Schedule is complete, true and correct, in all material
respects;

          (b) Payments Current. Except as set forth in Schedule 3.02(b), all
payments required to be made up to the Closing Date for the Mortgage Loan
under the terms of the Mortgage Note have been made and credited. No payment
required under the Mortgage Loan has been delinquent by more than thirty (30)
days more than one time within the twelve months preceding the Cut-off Date;

          (c) No Outstanding Charges. There are no defaults in complying with
the terms of the Mortgages, and Company 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. The Company has not advanced funds,
directly or indirectly, for the payment of any amount required under the
Mortgage Loan, except for interest accruing from the date of the Mortgage Note
or date of disbursement of the Mortgage Loan proceeds, whichever is greater,
to the day which precedes by one month the Due Date of the first installment
of principal and interest;

          (d) Original Terms Unmodified. The terms of the Mortgage Note and
Mortgage have not been impaired, waived, altered or modified in any respect,
except by a written instrument (which, if necessary to protect the interests
of the Purchaser, has been recorded) which has been delivered to the
Custodian;

          (e) No Defenses. The Mortgage Loan is not subject to any right of
rescission, set-off, counterclaim or defense, including without limitation the
defense of usury, nor will the operation of any of the terms of the Mortgage
Note or the Mortgage, or the exercise of any right thereunder, render either
the Mortgage Note or the Mortgage unenforceable, in whole or in part, or
subject to any right of rescission, set-off, counterclaim or defense,
including without limitation the defense of usury, and no such right of
rescission, set-off, counterclaim or defense has been asserted with respect
thereto, and Company has no knowledge that any Mortgagor was a debtor in any
state or federal bankruptcy or insolvency proceeding at the time the Mortgage
Loan was originated;

          (f) Hazard Insurance. Except in the case of Coop Loans, the Mortgage
requires all buildings or other improvements on the 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 Mortgaged Property is located pursuant to insurance policies conforming to
the requirements of Section 4.10. 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
Section 4.10. All individual insurance policies contain a standard mortgagee
clause naming the Company and its successors and assigns as mortgagee, and all
premiums thereon have been paid. The Mortgage obligates the 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, the 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 Purchaser
upon the consummation of the transactions contemplated by this Agreement. The
Company has not engaged in, and has no knowledge of the Mortgagor's or any
Subservicer's having engaged in, any act or omission which would impair the
coverage of any such policy, the benefits of the endorsement provided for
therein, or the validity and binding effect of either, including without
limitation, no unlawful fee, commission, kickback or other unlawful
compensation or value of any kind has been or will be received, retained or
realized by any attorney, firm or other person or entity, and no such unlawful
items have been received, retained or realized by the Company;

          (g) Compliance with Applicable Laws. Any and all requirements of any
federal, state or local law including, without limitation, usury,
truth-in-lending, real estate settlement procedures, consumer credit
protection, equal credit opportunity or disclosure laws applicable to the
Mortgage Loan have been complied with, and the Company shall maintain in its
possession, available for the Purchaser's inspection, and shall deliver to the
Purchaser upon demand, evidence of compliance with all such requirements;

          (h) No Satisfaction of Mortgage. The lien against the Mortgaged
Property has not been satisfied, canceled, 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 rescission. The
Company has not waived the performance by the Mortgagor of any action, if the
Mortgagor's failure to perform such action would cause the Mortgage Loan to be
in default, nor has the Company waived any default resulting from any action
or inaction by the Mortgagor;

          (i) Location and Type of Mortgaged Property. Except for Coop Loans,
the Mortgaged Property is located in the state identified in the Mortgage Loan
Schedule and consists of a parcel of real property with a detached single
family residence erected thereon or upon which a detached single family
residence will be erected, or a two- to four- family dwelling, or an
individual condominium unit in a condominium project, or an individual unit in
a planned unit development. For Coop Loans, the Mortgaged Property consists of
shares of stock in a cooperative housing corporation and a leasehold interest
in a cooperative apartment owned by such corporation located in the state
identified in the Mortgaged Loan Schedule;

          (j) Valid First Lien. The Mortgage is a valid, subsisting,
enforceable and perfected first lien on the Mortgaged Property. Where the
Mortgaged Property consists of residential real estate, the lien includes all
buildings on the Mortgaged Property and all installations and mechanical,
electrical, plumbing, heating and air conditioning systems located in or
annexed to such building, and all additions, alterations, and replacements
made at any time with respect to the foregoing. The lien of the Mortgage is
subject only to:

                    (1) the lien of current real property taxes and
               assessments not yet due and payable;

                    (2) covenants, conditions and restrictions, rights of way,
               easements and other matters of the public record as of the date
               of recording acceptable to mortgage lending institutions
               generally and specifically referred to in the lender's title
               insurance policy delivered to the originator of the Mortgage
               Loan and (i) referred to or otherwise considered in the
               appraisal made for the originator of the Mortgage Loan or (ii)
               which do not adversely affect the Appraised Value of the
               Mortgaged Property set forth in such appraisal; and

                    (3) other matters to which like properties are commonly
               subject which do not materially interfere with the benefits of
               the security intended to be provided by the Mortgage or the
               use, enjoyment, value or marketability of the related Mortgaged
               Property.

Any security agreement, chattel mortgage or equivalent document related to and
delivered in connection with the Mortgage Loan establishes and creates a
valid, subsisting and enforceable first lien and first priority security
interest on the Mortgaged Property and any additional collateral for the
Mortgage Loan and the Company has full right to sell and assign the same to
the Purchaser;

          (k) Validity of Mortgage Documents. The Mortgage Note and the
Mortgage are genuine, and each is the legal, valid and binding obligation of
the maker thereof enforceable in accordance with its terms. All parties to the
Mortgage Note and the Mortgage and any other related agreement had legal
capacity to enter into the Mortgage Loan and to execute and deliver the
Mortgage Note and the Mortgage and any other related agreement, and the
Mortgage Note and the Mortgage have been duly and properly executed by such
parties. The documents, instruments and agreements submitted for loan
underwriting were not falsified and contain no untrue statement of material
fact or omit to state a material fact required to be stated therein or
necessary to make the information and statements therein not misleading. No
fraud was committed in connection with the origination of the Mortgage Loan.
The Company has reviewed all of the documents constituting the Servicing File
and has made such inquiries as it deems necessary to make and confirm the
accuracy of the representations set forth herein;

          (l) Full Payment of Costs. All costs, fees and expenses incurred in
making or closing the Mortgage Loan and the recording of the Mortgage were
paid, and the Mortgagor is not entitled to any refund of any amounts paid or
due under the Mortgage Note or Mortgage;

          (m) Ownership. Immediately prior to the sale of the Mortgage Loans
by the Company to the Purchaser pursuant to this Agreement, the Company was
the sole owner of record and holder of the Mortgage Loan. The Mortgage Loan is
not assigned or pledged, and the Company has good and marketable title
thereto, and has full right to transfer and sell the Mortgage Loan therein to
the Purchaser free and clear 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;

          (n) Doing Business. All parties which have had any interest in the
Mortgage Loan, whether as mortgagee, assignee, pledgee or otherwise, are (or,
during the period in which they held and disposed of such interest, were) (1)
in compliance with any and all applicable licensing requirements of the laws
of the state wherein the real Mortgaged Property is located, and (2) organized
under the laws of such state, or (3) qualified to do business in such state,
or (4) federal savings and loan associations or national banks having
principal offices in such state, or (5) not doing business in such state;

          (o) LTV. No Mortgage Loan has a Loan-to-Value Ratio at origination
(or, if any Mortgage Loan has been the subject of a significant modification
since origination, other than as a result of a default or imminent default, as
of the date of such modification) equal to or greater than 90%.

          (p) Title Insurance. Except in the case of Coop Loans, the Mortgage
Loan is covered by either (i) an attorney's opinion of title and abstract of
title the form and substance of which is acceptable to mortgage lending
institutions making mortgage loans in the area where the Mortgaged Property is
located or (ii) an ALTA lender's title insurance policy or other generally
acceptable form of policy of insurance acceptable to FNMA or FHLMC, issued by
a title insurer acceptable to FNMA or FHLMC and qualified to do business in
the jurisdiction where the Mortgaged Property is located, insuring the
Company, its successors and assigns, as to the first priority lien of the
Mortgage in the original principal amount of the Mortgage Loan, and against
any loss by reason of the invalidity or enforceability of the lien resulting
from the provisions of the Mortgage providing for adjustment in the Mortgage
Interest Rate and Monthly Payment, subject only to the exceptions contained in
clauses (1), (2) and (3) of paragraph (j) of this Section 3.02 and against any
loss resulting from the provisions of the Mortgage providing for adjustment to
the Mortgage Interest Rate and Monthly Payment. Where required by state law or
regulation, the Mortgagor has been given the opportunity to choose the carrier
of the required mortgage title insurance. Additionally, such lender's title
insurance policy affirmatively insures ingress and egress, and against
encroachments by or upon the Mortgaged Property or any interest therein. 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. The Company is the sole insured of such lender's title
insurance policy, and such lender's title insurance policy is in full force
and effect and will be in force and effect upon the consummation of the loan
sale transaction contemplated by this Agreement. No claims have been made
under such lender's title insurance policy, and no prior holder of the
Mortgage, including the Company, has done, by act or omission, anything which
would impair the coverage of such lender's title insurance policy including
without limitation, no unlawful fee, commission, kickback or other unlawful
compensation or value of any kind has been or will be received, retained or
realized by any attorney, firm or other person or entity, and no such unlawful
items have been received, retained or realized by the Company;

          (q) No Defaults. There is no default, breach, violation or event of
acceleration existing under the Mortgage or the Mortgage Note and no event
which, with the passage of time or with notice and the expiration of any grace
or cure period, would constitute a default, breach, violation or event of
acceleration, and neither the Company nor its predecessors have waived any
default, breach, violation or event of acceleration, and no foreclosure action
has been commenced with respect to any Mortgage Loan;

          (r) No Mechanics' Liens. 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
Mortgaged Property which are or may be liens prior to, or equal or subordinate
with the lien of the related Mortgage;

          (s) Location of Improvements; No Encroachments. All improvements
which were considered in determining the Appraised Value of the Mortgaged
Property lay wholly within the boundaries and building restriction lines of
the Mortgaged Property (and, if the property is a condominium unit, such
improvements lie wholly within the project) and no improvements on adjoining
properties encroach upon the Mortgaged Property. No improvement located on or
being part of the Mortgaged Property is in violation of any applicable zoning
law or regulation;

          (t) Origination; Payment Terms. At the time the Mortgage Loan was
originated, the originator was a Mortgagee approved by the Secretary of
Housing and Urban Development pursuant to Sections 203 and 211 of the National
Housing Act or a savings and loan association, a savings bank, a commercial
bank or similar banking institution which is supervised and examined by a
Federal or State authority. The documents, instruments and agreements
submitted for loan underwriting were not falsified and contain no untrue
statement of material fact or omit to state a material fact required to be
stated therein or necessary to make the information and statements therein not
misleading. The Mortgage Interest Rate is adjusted on each Interest Rate
Adjustment Date to equal the Index plus the Gross Margin, which amount is
added in accordance with the terms of the Mortgage Note, subject to the
Mortgage Interest Rate Cap. The Mortgage Note is payable each month in
installments of principal and/or interest, which installments of interest are
subject to change due to the adjustments to the Mortgage Interest Rate on each
Interest Rate Adjustment Date, with interest calculated and payable in
arrears, sufficient to amortize the Mortgage Loan fully by the stated maturity
date, over an original term of not more than thirty (30) years. The Mortgage
Note provides for accrual of interest on the basis of a 360 day year
consisting of twelve 30-day months. There is no negative amortization. At no
time has the Mortgage Interest Rate exceeded the lifetime cap as set forth in
the related Note.

          (u) Customary Provisions. The Mortgage contains customary and
enforceable provisions such as to render the rights and remedies of the holder
thereof adequate for the realization against the Mortgaged Property of the
benefits of the security provided thereby, including (i) in the case of a
Mortgage designated as a deed of trust, by trustee's sale, and (ii) otherwise
by judicial foreclosure. Upon default by a Mortgagor on a Mortgage Loan,
foreclosure on, or trustee's sale of, the Mortgaged Property pursuant to the
proper procedures, the holder of the Mortgage Loan will be able to deliver
good and merchantable title to the Mortgaged Property. There is no homestead
or other exemption available to a Mortgagor which would interfere with the
right to sell the Mortgaged Property at a trustee's sale or the right to
foreclose the Mortgage;

          (v) Underwriting. The Mortgage Loans were generally underwritten and
approved substantially in accordance with the Company's written procedures and
standards set forth in Exhibit A-1.

          (w) Occupancy of the Mortgaged Property. As of the Closing Date the
Mortgaged Property (or, in the case of a Coop Loan, the related Cooperative
Unit) is lawfully occupied under applicable law. All inspections, licenses and
certificates required to be made or issued with respect to all occupied
portions of the Mortgaged Property (or, in the case of a Coop Loan, the
related Cooperative Unit) and, with respect to the use and occupancy of the
same, including but not limited to certificates of occupancy and fire
underwriting certificates, have been made or obtained from the appropriate
authorities;

          (x) No Additional Collateral. With the exception of Mortgage Loans
identified on the Mortgage Loan Schedule as having additional collateral, the
Mortgage Note is not secured by any collateral except the lien on Mortgaged
Property created by the corresponding Mortgage and the security interest or
any applicable security agreement or chattel mortgage referred to in Section
3.02(j) above;

          (y) Deeds of Trust. In the event the Mortgage constitutes a deed of
trust, a trustee, duly qualified under applicable law to serve as such, has
been properly designated and currently so serves and is named in the Mortgage,
and no fees or expenses are or will become payable by the Purchaser to the
trustee under the deed of trust, except in connection with a trustee's sale
after default by the Mortgagor;

          (z) Acceptable Investment. The Company has no knowledge of any
circumstances or conditions with respect to the Mortgage, the Mortgaged
Property, the Mortgagor and/or the Mortgagor's credit standing that can
reasonably be expected to:

               (i) cause private institutional investors to regard the
Mortgage Loan as an unacceptable investment;

               (ii) cause the Mortgage Loan to become delinquent; or

               (iii) adversely affect the value or marketability of the
Mortgage Loan;

     (aa) Delivery of Mortgage Documents. The Mortgage Loan Documents have
been delivered (or will have been released by the Closing Date) to the
Custodian. The Company is in possession of a complete, true and accurate
Mortgage File in compliance with Exhibit B, except for such documents the
originals of which have been delivered to the Custodian;

     (bb) Appraisal. The Mortgage File contains an appraisal of the related
Mortgaged Property conducted by a qualified appraiser, duly appointed by the
Company, who had no interest direct or indirect in the Mortgaged Property or
in any loan made on the security thereof, and whose compensation is not
affected by the approval or disapproval of the Mortgage Loan, and the
appraisal and appraiser both satisfy the requirements of Title XI of the
Federal Institution Reform, Recovery, and Enforcement Act of 1989 and the
regulations promulgated thereunder, all as in effect on the date the Mortgage
Loan was originated;

     (cc) Transfer of Mortgage Loans. The Assignment of Mortgage is in
recordable form and is acceptable for recording under the laws of the
jurisdiction in which the Mortgaged Property consisting of residential real
estate is located;

     (dd) Due on Sale. The Mortgage contains an enforceable provision for the
acceleration of the payment of the unpaid principal balance of the Mortgage
Loan in the event that the Mortgaged Property is sold or transferred without
the prior written consent of the mortgagee thereunder;

     (ee) Conversion to Fixed Interest Rate. Except as set forth in Schedule
3.02 (ee), the Mortgage Loan does not contain a provision permitting or
requiring conversion to a fixed interest rate Mortgage Loan;

     (ff) Consolidation of Future Advances. None of the Mortgage Loans contain
any provisions permitting future advances after the Cut-off Date. Any future
advances made prior to the Cut-off Date have been consolidated with the
outstanding principal amount secured by the Mortgage, and the secured
principal amount, as consolidated, bears a single interest rate and single
repayment term. Except in the case of Coop Loans, the lien of the Mortgage
securing the consolidated principal amounts is insured as having first lien
priority by a title insurance policy, and endorsement to the policy insuring
the mortgagee's consolidated interest or by other title evidence. The
consolidated principal amount does not exceed the original principal amount of
the Mortgage Loan;

     (gg) Mortgaged Property Undamaged. There is no proceeding pending or, to
the best of the Company's knowledge, threatened for the total or partial
condemnation of the Mortgaged Property. The Mortgaged Property is undamaged by
waste, fire, earthquake or earth movement, windstorm, flood, tornado or other
casualty so as to affect adversely the value of the Mortgaged Property as
security for the Mortgage Loan or the use for which the premises were
intended;

     (hh) Collection Practices; Escrow Deposits; Interest Rate Adjustments.
The origination and collection practices used with respect to the Mortgage
Loan have been in accordance with Accepted Servicing Practices, and have been
in all respects in compliance with all applicable laws and regulations. All
Mortgage Interest Rate adjustments have been made in compliance with state and
federal law and the terms of the related Mortgage Note. Any interest required
to be paid pursuant to state and local law has been properly paid and
credited;

     (ii) Environmental Matters. To the best of the Company's knowledge, the
Mortgaged Property is free from any and all toxic or hazardous substances and
there exists no violation of any local, state or federal environmental law,
rule or regulation;

     (jj) Soldiers' and Sailors' Relief Act. The Mortgagor has not notified
the Company, and the Company has no knowledge, of any relief requested or
allowed to the Mortgagor under the Soldiers' and Sailors' Civil Relief Act of
1940;

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

     (ll) Buydown Mortgage Loans. None of the Mortgage Loans is a Buydown
Mortgage Loan; and

     (mm) No Partial Release of Collateral. No Mortgage Loan requires the
Mortgagee to release any portion of the Mortgaged Property from the lien of
the Mortgage other than (i) upon payment in full of the Mortgage Loan or (ii)
with respect to Mortgaged Property consisting of more than one piece of real
property or shares of a cooperative corporation, a release of a portion of the
Mortgaged Property upon a partial repayment of the Mortgage Loan, provided the
LTV of the remaining Mortgaged Property after the release does not exceed 90%.

     Section 3.03. Remedies for Breach of Representations and Warranties

     It is understood and agreed that the representations and warranties set
forth in Sections 3.01 and 3.02 shall survive the sale of the Mortgage Loans
to the Purchaser and the subsequent sale of the Mortgage Loans by the
Purchaser to the Depositor and by the Depositor to the Trustee under the Trust
Agreement, and the delivery of the Mortgage Loan Documents to the Custodian
and shall inure to the benefit of the Purchaser, specifically, including the
Trustee, as provided in Section 11.10 hereof, notwithstanding any restrictive
or qualified endorsement on any Mortgage Note or Assignment of Mortgage or the
examination or failure to examine any Mortgage File. Upon discovery by either
the Company or the Purchaser of a breach of any of the foregoing
representations and warranties which materially and adversely affects the
value of the Mortgage Loans or the interest of the Purchaser (or which
materially and adversely affects the interests of the Purchaser in the related
Mortgage Loan in the case of a representation and warranty relating to a
particular Mortgage Loan) the party discovering such breach shall give prompt
written notice to the other.

     Within sixty (60) days of the earlier of either discovery by or notice to
the Company of any breach of a representation or warranty which materially and
adversely affects the value of the Mortgage Loans or the interest of the
Purchaser (or which materially and adversely affects the interests of
Purchaser in the related Mortgage Loan in the case of a representation and
warranty relating to a particular Mortgage Loan), the Company shall use its
best efforts promptly to cure such breach in all material respects and, if
such breach cannot be cured, the Company shall, at the Purchaser's option,
repurchase such Mortgage Loan at the Repurchase Price. In the event that a
breach shall involve any representation or warranty set forth in Section 3.01,
and either discovery by or notice to the Company of such breach, all of the
Mortgage Loans shall, at the Purchaser's option, be repurchased by the Company
at the Repurchase Price. However, if the breach shall involve a representation
or warranty set forth in Section 3.02 and the Company discovers or receives
notice of any such breach within 120 days of the Closing Date, the Company
shall, at the Purchaser's option and provided that the Company has a Qualified
Substitute Mortgage Loan, rather than repurchase the Mortgage Loan as provided
above, remove such Mortgage Loan (a "Deleted Mortgage Loan") and substitute in
its place a Qualified Substitute Mortgage Loan or Loans, provided that no such
substitution shall be made (i) after the 120-day period beginning on the
Closing Date and (ii) unless the Purchaser has received an Opinion of Counsel
(at the expense of the Company) that such substitution will not adversely
affect the status of any REMIC established pursuant to the Trust Agreement as
a REMIC or cause any such REMIC to be deemed to have engaged in a "prohibited
transaction" under the REMIC provisions. If the Company has no Qualified
Substitute Mortgage Loan, it shall repurchase the deficient Mortgage Loan. Any
repurchase of a Mortgage Loan or Loans pursuant to the foregoing provisions of
this Section 3.03 shall be accomplished by deposit in the Custodial Account of
the amount of the Repurchase Price for distribution to Purchaser on the next
scheduled Remittance Date, after deducting therefrom any amount received in
respect of such repurchased Mortgage Loan or Loans and being held in the
Custodial Account for future distribution.

     At the time of repurchase or substitution, the Purchaser and the Company
shall arrange for the reassignment of the Deleted Mortgage Loan to the Company
and the delivery to the Company of any documents held by the Custodian
relating to the Deleted Mortgage Loan. In the event of a repurchase or
substitution, the Company shall, simultaneously with such reassignment, give
written notice to the Purchaser that such repurchase or substitution has taken
place, amend the Mortgage Loan Schedule to reflect the withdrawal of the
Deleted Mortgage Loan from this Agreement, and, in the case of substitution,
identify a Qualified Substitute Mortgage Loan and amend the Mortgage Loan
Schedule to reflect the addition of such Qualified Substitute Mortgage Loan to
this Agreement. In connection with any such substitution, the Company shall be
deemed to have made as to such Qualified Substitute Mortgage Loan the
representations and warranties set forth in this Agreement except that all
such representations and warranties set forth in this Agreement shall be
deemed made as of the date of such substitution. The Company shall effect such
substitution by delivering to the Custodian for such Qualified Substitute
Mortgage Loan the related Mortgage Loan Documents with the Mortgage Note
endorsed as required. No substitution will be made in any calendar month after
the Determination Date for such month. The Company shall deposit in the
Custodial Account the Monthly Payment less the Servicing Fee due on such
Qualified Substitute Mortgage Loan or Loans in the month following the date of
such substitution. Monthly Payments due with respect to Qualified Substitute
Mortgage Loans in the month of substitution shall be retained by the Company.
For the month of substitution, distributions to Purchaser shall include the
Monthly Payment due on any Deleted Mortgage Loan in the month of substitution.
The Company shall thereafter be entitled to retain all amounts subsequently
received by the Company in respect of such Deleted Mortgage Loan.

     For any month in which the Company substitutes a Qualified Substitute
Mortgage Loan for a Deleted Mortgage Loan the Company shall determine the
amount (if any) by which the aggregate principal balance of all Qualified
Substitute Mortgage Loans as of the date of substitution is less than the
aggregate Stated Principal Balance of all Deleted Mortgage Loans (after
application of scheduled principal payments due in the month of substitution).
The amount of such shortfall shall be distributed by the Company in the month
of substitution pursuant to Section 5.01. Accordingly, on the date of such
substitution, the Company shall deposit from its own funds into the Custodial
Account an amount equal to the amount of such shortfall.

     In addition to such repurchase or substitution obligation, the Company
shall indemnify the Purchaser and hold it harmless against any losses,
damages, penalties, fines, forfeitures, reasonable and necessary 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 Company's representations and warranties contained in
this Agreement. It is understood and agreed that the obligations of the
Company set forth in this Section 3.03 to cure, substitute for or repurchase a
defective Mortgage Loan and to indemnify the Purchaser as provided in this
Section 3.03 constitute the sole remedies of the Purchaser respecting a breach
of the foregoing representations and warranties.

     Any cause of action against the Company relating to or arising out of the
breach of any representations and warranties made in Section 3.01 and 3.02
shall accrue as to any Mortgage Loan upon (i) discovery of such breach by the
Purchaser or notice thereof by the Company to the Purchaser, (ii) failure by
the Company to cure such breach or repurchase such Mortgage Loan as specified
above, and (iii) demand upon the Company by the Purchaser for compliance with
this Agreement.

     Section 3.04.  Mortgage Loans Convertible to Fixed Interest Rate.

     In the event the Mortgagor under any Convertible Mortgage Loan elects to
convert said Mortgage Loan to a fixed interest rate Mortgage Loan, as provided
in the related Mortgage Note, then the Company shall repurchase such Mortgage
Loan at the Repurchase Price or substitute in its place a Qualified Substitute
Mortgage Loan or Loans in the manner prescribed in Section 3.03.

                                  ARTICLE IV

                ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

     Section 4.01. Company to Act as Servicer.

     The Company, as an independent contractor, shall service and administer
the Mortgage Loans and shall have full power and authority, acting alone, to
do any and all things in connection with such servicing and administration
which the Company may deem necessary or desirable, consistent with the terms
of this Agreement and with Accepted Servicing Practices.

     Consistent with the terms of this Agreement, the Company 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 Company shall not make
any future advances with respect to a Mortgage Loan and (unless the Mortgagor
is in default with respect to the Mortgage Loan or such default is, in the
judgment of the Company, imminent) the Company shall not permit any
modification 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, unless approved by Purchaser on a
Mortgage Loan-by-Mortgage Loan basis (which approval shall not be unreasonably
withheld, conditioned or delayed), or unless pursuant to a loan modification
program previously presented to and approved by the Purchaser. In the event of
any such modification which permits the deferral of interest or principal
payments on any Mortgage Loan, the Company shall, on the Business Day
immediately preceding the Remittance Date in any month in which any such
principal or interest payment has been deferred, deposit in the Custodial
Account from its own funds, in accordance with Section 5.03, the difference
between (a) such month's principal and one month's interest at the Mortgage
Loan Remittance Rate on the unpaid principal balance of such Mortgage Loan and
(b) the amount paid by the Mortgagor. The Company shall be entitled to
reimbursement for such advances to the same extent as for all other advances
made pursuant to Section 5.03. Without limiting the generality of the
foregoing, the Company shall continue, and is hereby authorized and empowered,
to execute, deliver and record (if appropriate) on behalf of itself and the
Purchaser, all instruments of satisfaction or cancellation, or of partial or
full release, discharge and all other comparable instruments and any other
certificate or instrument necessary to carry out the modifications
contemplated by this Section 4.01, with respect to the Mortgage Loans and with
respect to the Mortgaged Properties. The Purchaser has furnished and upon
request shall furnish the Company with any powers of attorney and other
documents reasonably required by the Company which are necessary or
appropriate to enable the Company to carry out its servicing and
administrative duties under this Agreement.

     In the event that foreclosure proceedings are commenced in respect of any
Mortgage Loan as to which Additional Collateral has been pledged as security,
the Company shall, if such Additional Collateral is readily marketable,
immediately commence the liquidation of such collateral. The proceeds of such
sale shall be promptly deposited in the Custodial Account. If such Additional
Collateral is not readily marketable, the Company shall not exercise any right
it may have to seize, convert or otherwise assume ownership of such Additional
Collateral.

     In servicing and administering the Mortgage Loans, the Company shall
employ procedures (including collection procedures) and exercise the same care
that it customarily employs and exercises in servicing and administering
mortgage loans for its own account, giving due consideration to Accepted
Servicing Practices where such practices do not conflict with the requirements
of this Agreement, and the Purchaser's reliance on the Company.

     The Mortgage Loans may be subserviced by the Subservicer, in accordance
with the servicing provisions of this Agreement, on behalf of the Company,
provided that the Subservicer is a FNMA-approved lender or a FHLMC
seller/servicer in good standing, and no event has occurred, including but not
limited to a change in insurance coverage, which would make it unable to
comply with the eligibility requirements for lenders imposed by FNMA or for
seller/servicers imposed by FHLMC, or which would require notification to FNMA
or FHLMC. The Company may perform any of its servicing responsibilities
hereunder or may cause the Subservicer to perform any such servicing
responsibilities on its behalf, but the use by the Company of the Subservicer
shall not release the Company from any of its obligations hereunder and the
Company shall remain responsible hereunder for all acts and omissions of the
Subservicer as fully as if such acts and omissions were those of the Company.
The Company shall pay all fees and expenses of the Subservicer from its own
funds, and the Subservicer's fee shall not exceed the Servicing Fee.

     References in this Agreement to performance by the Company of its
servicing responsibilities hereunder shall be deemed to include the
Subservicer acting on behalf of the Company.

     At the cost and expense of the Company, without any right of
reimbursement from the Custodial Account, the Company shall be entitled to
terminate the rights and responsibilities of the Subservicer and arrange for
any servicing responsibilities to be performed by a successor Subservicer
meeting the requirements in the two preceding paragraphs; provided, however,
that nothing contained herein shall be deemed to prevent or prohibit the
Company, at the Company's option, from electing to service the related
Mortgage Loans itself. In the event that the Company's responsibilities and
duties under this Agreement are terminated pursuant to Section 8.04, 9.01,
10.01 or 10.02 , and if requested to do so by the Purchaser, the Company shall
at its own cost and expense terminate the rights and responsibilities of the
Subservicer as soon as is reasonably possible. The Company shall pay all fees,
expenses or penalties necessary in order to terminate the rights and
responsibilities of the Subservicer from the Company's own funds without
reimbursement from the Purchaser.

     Notwithstanding any of the provisions of this Agreement relating to
agreements or arrangements between the Company and the Subservicer or any
reference herein to action taken though the Subservicer or otherwise, the
Company shall not be relieved of its obligations to the Purchaser and shall be
obligated to the same extent and under the same terms and conditions as if it
alone were servicing and administering the Mortgage Loans. The Company shall
be entitled to enter into an agreement with the Subservicer for
indemnification of the Company by the Subservicer and nothing contained in
this Agreement shall be deemed to limit or modify such indemnification.

     Any Subservicing Agreement and any other transactions or services
relating to the Mortgage Loans involving the Subservicer shall be deemed to be
between the Subservicer and Company alone, and the Purchaser shall have no
obligations, duties or liabilities with respect to the Subservicer including
no obligation, duty or liability of Purchaser to pay the Subservicer's fees
and expenses. For purposes of distributions and advances by the Company
pursuant to this Agreement, the Company shall be deemed to have received a
payment or other recovery in respect of a Mortgage Loan when the Subservicer
has received such payment or recovery.

     Section 4.02. Liquidation of Mortgage Loans.

     In the event that any payment due under any Mortgage Loan and not
postponed pursuant to Section 4.01 is not paid when the same becomes due and
payable, or in the event the Mortgagor fails to perform any other covenant or
obligation under the Mortgage Loan and such failure continues beyond any
applicable grace period, the Company shall take such action as (1) the Company
would take under similar circumstances with respect to a similar mortgage loan
held for its own account for investment, (2) shall be consistent with Accepted
Servicing Practices, and (3) the Company shall determine prudently to be in
the best interest of Purchaser. In the event that any payment due under any
Mortgage Loan is not postponed pursuant to Section 4.01 and remains delinquent
for a period of ninety (90) days or any other default continues for a period
of ninety (90) days beyond the expiration of any grace or cure period, the
Company shall commence foreclosure proceedings, provided that, prior to
commencing foreclosure proceedings, the Company shall notify the Purchaser in
writing of the Company's intention to do so, and the Company shall not
commence foreclosure proceedings if the Purchaser objects to such action
within ten (10) Business Days of receiving such notice. The Company's
obligation to make such Monthly Advances shall terminate upon delivery by the
Company to the Purchaser of a Certificate of Nonrecoverable Advance in the
form set forth in Exhibit M.

     Notwithstanding anything to the contrary contained herein, in connection
with a foreclosure or acceptance of a deed in lieu of foreclosure, in the
event the Company has reasonable cause to believe that a Mortgaged Property is
contaminated by hazardous or toxic substances or wastes, or if the Purchaser
otherwise requests an environmental inspection, a review of such Mortgaged
Property shall be conducted by a qualified inspector. Upon completion of the
inspection, the Company shall promptly provide the Purchaser with a written
report of the environmental inspection.

     In the event that the environmental inspection report indicates that the
Mortgaged Property is contaminated by hazardous or toxic substances or wastes,
the Company shall not proceed with foreclosure or acceptance of a deed in lieu
of foreclosure, and the Company shall be reimbursed for all Servicing Advances
made with respect to the related Mortgaged Property from the Custodial Account
pursuant to Section 4.05 hereof.

     Section 4.03. Collection of Mortgage Loan Payments.

     Continuously from the date hereof until the principal and interest on all
Mortgage Loans are paid in full, the Company shall proceed diligently to
collect all payments due under each of the Mortgage Loans when the same shall
become due and payable and shall take special care in ascertaining and
estimating Escrow Payments and all other charges that will become due and
payable with respect to the Mortgage Loan and the Mortgaged Property, to the
end that the installments payable by the Mortgagor will be sufficient to pay
such charges as and when they become due and payable.

     Section 4.04. Establishment of and Deposits to Custodial Account.

     The Company shall segregate and hold all funds collected and received
pursuant to a Mortgage Loan separate and apart from any of its own funds and
general assets and shall establish and maintain one or more Custodial
Accounts, in the form of time deposit or demand accounts, titled "Boston Safe
Deposit and Trust Company in trust for Norwest Bank Minnesota, National
Association, as Trustee, Structured Asset Securities Corporation Mortgage
Pass-Through Certificates, Series 1998-5," or such other designation as the
Purchaser may direct. The Custodial Account shall be established with a
Qualified Depository. Any funds deposited in the Custodial Account shall at
all times be fully insured to the full extent permitted under applicable law.
Funds deposited in the Custodial Account may be drawn on by the Company in
accordance with Section 4.05. The creation of any Custodial Account shall be
evidenced by a certification in the form of Exhibit D-1 hereto, in the case of
an account established with the Company, or by a letter agreement in the form
of Exhibit D-2 hereto, in the case of an account held by a depository other
than the Company. A copy of such certification or letter agreement shall be
furnished to the Purchaser and, upon request, to any subsequent Purchaser.

     Funds in a Custodial Account may be invested in Eligible Investments (as
defined in the Trust Agreement) which shall mature not later than the earlier
of the Business Day immediately preceding the next succeeding Remittance Date,
and such investments shall not be sold or disposed of prior to their maturity.
All income and gain realized from any investment shall be for the benefit of
the Company and shall be subject to its withdrawal or order. The amount of any
losses incurred in respect of any such investments shall be deposited in the
related Custodial Account by the Company out of its own funds immediately as
such loss is realized.

     The Company shall deposit in the Custodial Account on a daily basis, as
received, and retain therein, the following collections received by the
Company and payments made by the Company after the Cut-off Date, other than
payments of principal and interest due on or before the Cut-off Date:

          (i) all payments on account of principal on the Mortgage Loans,
including all Principal Prepayments;

          (ii) all payments on account of interest on the Mortgage Loans
adjusted to the Mortgage Loan Remittance Rate;

          (iii) all Liquidation Proceeds;

          (iv) all Insurance Proceeds including amounts required to be
deposited pursuant to Section 4.10 (other than proceeds to be held in the
Escrow Account and applied to the restoration or repair of the Mortgaged
Property or released to the Mortgagor in accordance with Section 4.14) and
Section 4.11;

          (v) all Condemnation Proceeds which are not applied to the
restoration or repair of the Mortgaged Property or released to the Mortgagor
in accordance with Section 4.14;

          (vi) any amount required to be deposited in the Custodial Account
pursuant to Section 4.01, 4.04, 5.03, 6.01 or 6.02;

          (vii) any amounts payable in connection with the repurchase of any
Mortgage Loan pursuant to Section 3.03 and all amounts required to be
deposited by the Company in connection with a shortfall in principal amount of
any Qualified Substitute Mortgage Loan pursuant to Section 3.03;

          (viii) with respect to each Principal Prepayment received during the
immediately preceding Principal Prepayment Period, an amount (to be paid by
the Company out of its funds as provided in Section 6.03 hereof) which, when
added to all amounts allocable to interest received in connection with such
Principal Prepayment, equals one month's interest on the amount of principal
so prepaid at the Mortgage Loan Remittance Rate, the aggregate of such
payments by the Company for any month not to exceed the aggregate of the
Company's Servicing Fees for such month.

          (ix) any amounts required to be deposited by the Company pursuant to
Section 4.11 in connection with the deductible clause in any blanket hazard
insurance policy; and

          (x) any amounts received with respect to or related to any REO
Property and all REO Disposition Proceeds pursuant to Section 4.15.

     The foregoing requirements for deposit into the Custodial Account shall
be exclusive, it being understood and agreed that, without limiting the
generality of the foregoing, payments in the nature of late payment charges
and assumption fees, to the extent permitted by Section 6.01, need not be
deposited by the Company into the Custodial Account. Any interest paid on
funds deposited in the Custodial Account by the depository institution shall
accrue to the benefit of the Company and the Company shall be entitled to
retain and withdraw such interest from the Custodial Account pursuant to
Section 4.05.

     Section 4.05. Permitted Withdrawals From Custodial Account.

     The Company shall, from time to time, withdraw funds from the Custodial
Account for the following purposes:

          (i) to make payments to the Purchaser in the amounts and in the
manner provided for in Section 5.01;

          (ii) to reimburse itself for Monthly Advances of the Company's funds
made pursuant to Section 5.03, the Company's right to reimburse itself
pursuant to this subclause (ii) being limited to amounts received with respect
to the related Mortgage Loan which represent late payments of principal and/or
interest respecting which any such advance was made, it being understood that,
in the case of any such reimbursement, the Company's right thereto shall be
prior to the rights of the Purchaser, except that, where the Company is
required to repurchase a Mortgage Loan pursuant to Section 3.03 or 6.02, the
Company's right to such reimbursement shall be subsequent to the payment to
the Purchaser of the Repurchase Price pursuant to such sections and all other
amounts required to be paid to the Purchaser with respect to such Mortgage
Loan;

          (iii) to reimburse itself for unreimbursed Servicing Advances, and
for any unpaid Servicing Fees, the Company's right to reimburse itself
pursuant to this subclause (iii) with respect to any Mortgage Loan being
limited to related Liquidation Proceeds, Condemnation Proceeds, Insurance
Proceeds and such other amounts as may be collected by the Company from the
Mortgagor or otherwise relating to the Mortgage Loan, it being understood
that, in the case of any such reimbursement, the Company's right thereto shall
be prior to the rights of Purchaser except where the Company is required to
repurchase a Mortgage Loan pursuant to Section 3.03 or 6.02, in which case the
Company's right to such reimbursement shall be subsequent to the payment to
the Purchaser of the Repurchase Price pursuant to such sections and all other
amounts required to be paid to the Purchaser with respect to such Mortgage
Loan;

          (iv) to pay itself investment earnings on funds deposited in the
Custodial Account;

          (v) to reimburse itself for expenses incurred and reimbursable to it
pursuant to Sections 4.02 and 8.01;

          (vi) to pay any amount required to be paid pursuant to Sections 4.02
and 4.15 related to any REO Property, it being understood that in the case of
any such expenditure or withdrawal related to a particular REO Property, the
amount of such expenditure or withdrawal from the Custodial Account shall be
limited to amounts on deposit in the Custodial Account with respect to the
related REO Property;

          (vii) to withdraw funds deposited in error in the Custodial Account;
and

          (viii) to clear and terminate the Custodial Account upon the
termination of this Agreement.

     On each Remittance Date, the Company shall withdraw all funds from the
Custodial Account except for those amounts which, pursuant to Section 5.01,
the Company is not obligated to remit on such Remittance Date. The Company may
use such withdrawn funds only for the purposes described in this Section 4.05.

     Section 4.06. Establishment of and Deposits to Escrow Account.

     The Company shall segregate and hold all funds collected and received
pursuant to a Mortgage Loan constituting Escrow Payments separate and apart
from any of its own funds and general assets and shall establish and maintain
one or more Escrow Accounts, in the form of time deposit or demand accounts
titled, "Boston Safe Deposit and Trust Company, in trust for Norwest Bank
Minnesota, National Association, as Trustee, Structured Asset Securities
Corporation Mortgage Pass-Through Certificates, Series 1998-5," or such other
designation as the Purchaser may direct. The Escrow Account shall be
established with a Qualified Depository, in a manner which shall provide
maximum available insurance thereunder. Funds deposited in the Escrow Account
may be drawn on by the Company in accordance with Section 4.07. The creation
of any Escrow Account shall be evidenced by a certification in the form of
Exhibit E-1 hereto, in the case of an account established with the Company, or
by a letter agreement in the form of Exhibit E-2 hereto, in the case of an
account held by a depository other than the Company. A copy of such
certification shall be furnished to the Purchaser and, upon request, to any
subsequent Purchaser.

     The Company shall deposit in the Escrow Account or Accounts on a daily
basis, and retain therein:

          (i) all Escrow Payments collected on account of the Mortgage Loans,
for the purpose of effecting timely payment of any such items as required
under the terms of this Agreement; and

          (ii) all amounts representing Insurance Proceeds or Condemnation
Proceeds which are to be applied to the restoration or repair of any Mortgaged
Property.

     The Company shall make withdrawals from the Escrow Account only to effect
such payments as are required or permitted under this Agreement, as set forth
in Section 4.07. The Company shall be entitled to retain any interest paid on
funds deposited in the Escrow Account by the depository institution, other
than interest on escrowed funds required by law to be paid to the Mortgagor.
To the extent required by law, the Company shall pay interest on escrowed
funds to the Mortgagor notwithstanding that the Escrow Account may be
non-interest bearing or that interest paid thereon is insufficient for such
purposes.

     Section 4.07. Permitted Withdrawals From Escrow Account.

     Withdrawals from the Escrow Account or Accounts may be made by the
Company only:

          (i) to effect timely payments of ground rents, taxes, assessments,
water rates, mortgage insurance premiums, condominium charges, fire, flood and
hazard insurance premiums or other items constituting Escrow Payments for the
related Mortgage;

          (ii) to reimburse the Company for any Servicing Advances made by the
Company pursuant to Section 4.08 with respect to a related Mortgage Loan, but
only from amounts received on the related Mortgage Loan which represent late
collections of Escrow Payments thereunder;

          (iii) to refund to any Mortgagor any funds found to be in excess of
the amounts required under the terms of the related Mortgage Loan;

          (iv) for transfer to the Custodial Account and application to reduce
the principal balance of the Mortgage Loan in accordance with the terms of the
related Mortgage and Mortgage Note;

          (v) for application to restoration or repair of the Mortgaged
Property in accordance with the procedures outlined in Section 4.14;

          (vi) to pay to the Company, or any Mortgagor to the extent required
by law, any interest paid on the funds deposited in the Escrow Account;

          (vii) to withdraw funds deposited in error in the Escrow Account;
and

          (viii) to clear and terminate the Escrow Account on the termination
of this Agreement.

     Section 4.08. Maintenance of Tax, Insurance, Other Charge Records.

     With respect to each Mortgage Loan, the Company shall maintain accurate
records reflecting the status of ground rents, taxes, assessments, water
rates, sewer rents, and the charges which are or may become a lien upon the
Mortgaged Property and the status of fire, flood and hazard insurance coverage
and with respect to each Mortgage Loan which provides for Escrow Payments, the
Company shall obtain, from time to time, all bills for the payment of such
charges (including renewal premiums) and shall effect payment thereof prior to
the applicable penalty or termination date, employing for such purpose
deposits of the Mortgagor in the Escrow Account which shall have been
estimated and accumulated by the Company in amounts sufficient for such
purposes, as allowed under the terms of the Mortgage. To the extent that a
Mortgage does not provide for Escrow Payments, the Company shall make a
Servicing Advance from its own funds to effect payment for such charges in
accordance with Accepted Servicing Practices.

     Section 4.09. Protection of Accounts

     The Company may transfer the Custodial Account or the Escrow Account to a
different Qualified Depository from time to time. Such transfer shall be made
only upon obtaining the consent of the Purchaser, which consent shall not be
withheld unreasonably.

     The Company shall bear any expenses, losses or damages sustained by the
Purchaser because the Custodial Account or Escrow Account is not a demand
deposit account.

     Section 4.10. Maintenance of Hazard Insurance.

     The Company shall cause to be maintained for each Mortgage Loan hazard
insurance such that all buildings upon the Mortgaged Property are insured by a
FNMA or FHLMC acceptable insurer against loss by fire, hazards of extended
coverage and such other hazards as are customary in the area where the
Mortgaged Property is located, in an amount which is at least equal to the
lesser of (i) the maximum insurable value of the improvements securing such
Mortgage Loan and (ii) the greater of (a) the outstanding principal balance of
the Mortgage Loan and (b) an amount such that the proceeds thereof shall be
sufficient to prevent the Mortgagor or the loss payee from becoming a
co-insurer.

     If upon origination of the Mortgage Loan, the related Mortgaged Property
was located in an area identified in the Federal Register by the Flood
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 with a generally acceptable insurance carrier in
an amount representing coverage equal to the lesser of (i) the minimum amount
required, under the terms of coverage, to compensate for any damage or loss on
a replacement-cost basis or the unpaid balance of the Mortgage Loan if
replacement coverage is not available for the type of building insured) and
(ii) the maximum amount of insurance which is available under the Flood
Disaster Protection Act of 1973, as amended.

     If a Mortgage is secured by a unit in a condominium, the Company shall
have received a certificate of insurance evidencing a master policy held by
the owner's association and naming the Company as loss payee.

     In the event that the Purchaser or the Company shall determine that the
Mortgaged Property (or, in the case of a Cooperative Loan, the related
Cooperative Unit) should be insured against loss or damage by hazards and
risks not covered by the insurance required to be maintained by the Mortgagor
pursuant to the terms of the Mortgage, the Company shall communicate and
consult with the Mortgagor with respect to the need for such insurance and
bring to the Mortgagor's attention the desirability of protection of the
Mortgaged Property.

     All policies required hereunder shall name the Company as loss payee and
shall be endorsed with standard mortgagee clauses, which shall provide for at
least 30 days' prior written notice of any cancellation, reduction in amount
or material change in coverage.

     The Company shall not interfere with the Mortgagor's freedom of choice in
selecting either his insurance carrier or agent; provided, however, that the
Company shall not accept any such insurance policies from insurance companies
unless such companies satisfy the requirements of FNMA or FHLMC and are
licensed to do business in the jurisdiction in which the Mortgaged Property is
located. The Company shall determine that such policies provide sufficient
risk coverage and amounts, that they insure the property owner, and that they
properly describe the property address. The Company shall furnish to the
Mortgagor a formal notice of expiration of any such insurance in sufficient
time for the Mortgagor to arrange for renewal coverage by the expiration date.

     Pursuant to Section 4.04, any amounts collected by the Company under any
such policies (other than amounts to be deposited in the Escrow Account and
applied to the restoration or repair of the related Mortgaged Property (or, in
the case of a Cooperative Loan, the related Cooperative Unit), or property
acquired in liquidation of the Mortgage Loan, or to be released to the
Mortgagor, in accordance with the Company's normal servicing procedures as
specified in Section 4.14) shall be deposited in the Custodial Account subject
to withdrawal pursuant to Section 4.05.

     Section 4.11. Maintenance of Mortgage Impairment Insurance

     The Company shall maintain a blanket policy insuring against losses
arising from fire and hazards covered under extended coverage on any or all of
the Mortgage Loans and, to the extent such policy provides coverage in an
amount equal to the amount required pursuant to Section 4.10 and otherwise
complies with all other requirements of Section 4.10, it shall conclusively be
deemed to have satisfied its obligations as set forth in Section 4.10. Any
amounts collected by the Company under any such policy relating to a Mortgage
Loan shall be deposited in the Custodial Account subject to withdrawal
pursuant to Section 4.05. Such policy may contain a deductible clause, in
which case, in the event that there shall not have been maintained on the
related Mortgaged Property a policy complying with Section 4.10, and there
shall have been a loss which would have been covered by such policy, the
Company shall deposit in the Custodial Account at the time of such loss the
amount not otherwise payable under the blanket policy because of such
deductible clause, such amount to deposited from the Company's funds, without
reimbursement therefor. Upon request of the Purchaser, the Company shall cause
to be delivered to such Purchaser a certified true copy of such policy and a
statement from the insurer thereunder that such policy shall in no event be
terminated or materially modified without thirty (30) days' prior written
notice to the Purchaser.

     Section 4.12. Maintenance of Fidelity Bond and Errors and Omissions
Insurance.

     The Company or its corporate parent shall maintain on behalf of the
Company with responsible companies, at its own expense, a blanket Fidelity
Bond and an Errors and Omissions Insurance Policy, with broad coverage on all
officers, employees or other persons acting in any capacity requiring such
persons to handle funds, money, documents or papers relating to the Mortgage
Loans ("Company Employees"). Any such Fidelity Bond and Errors and Omissions
Insurance Policy shall be in the form of the Mortgage Banker's Blanket Bond
and shall protect and insure the Company against losses, including forgery,
theft, embezzlement, fraud, errors and omissions and negligent acts of such
Company Employees. Such Fidelity Bond and Errors and Omissions Insurance
Policy also shall protect and insure the Company against losses in connection
with the release or satisfaction of a Mortgage Loan without having obtained
payment in full of the indebtedness secured thereby. No provision of this
Section 4.12 requiring such Fidelity Bond and Errors and Omissions Insurance
Policy shall diminish or relieve the Company from its duties and obligations
as set forth in this Agreement. The minimum coverage under any such bond and
insurance policy shall be at least equal to the corresponding amounts required
by FNMA in the FNMA Mortgage-Backed Securities Selling and Servicing Guide or
by FHLMC in the FHLMC Sellers' & Servicers' Guide. Upon the request of the
Purchaser, the Company shall cause to be delivered to the Purchaser a
certified true copy of such fidelity bond and insurance policy and a statement
from the surety and the insurer that such fidelity bond and insurance policy
shall in no event be terminated or materially modified without thirty (30)
days' prior written notice to the Purchaser.

     Section 4.13.  Inspections.

     The Company shall inspect the Mortgaged Property as often as deemed
necessary by the Company to assure itself that the value of the Mortgaged
Property is being preserved. In addition, if any Mortgage Loan is more than
sixty (60) days delinquent, the Company immediately shall inspect the
Mortgaged Property and shall conduct subsequent inspections in accordance with
Accepted Servicing Practices. The Company shall keep a written report of each
such inspection.

         Section 4.14. Restoration of Mortgaged Property.

     The Company need not obtain the approval of the Purchaser prior to
releasing any Insurance Proceeds or Condemnation Proceeds to the Mortgagor to
be applied to the restoration or repair of the Mortgaged Property if such
release is in accordance with Accepted Servicing Practices. At a minimum, the
Company shall comply with the following conditions in connection with any such
release of Insurance Proceeds or Condemnation Proceeds:

          (i) the Company shall receive satisfactory independent verification
of completion of repairs and issuance of any required approvals with respect
thereto;

          (ii) the Company shall take all steps necessary to preserve the
priority of the lien of the Mortgage, including, but not limited to requiring
waivers with respect to mechanics' and materialmen's liens; and

          (iii) pending repairs or restoration, the Company shall place the
Insurance Proceeds or Condemnation Proceeds in the Escrow Account.

     If the Purchaser is named as an additional loss payee, the Company is
hereby empowered to endorse any loss draft issued in respect of such a claim
in the name of the Purchaser.

     Section 4.15. Title, Management and Disposition of REO Property.

     In the event that title to any Mortgaged Property is acquired in
foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale
shall be taken in the name of the Purchaser, or in the event the Purchaser is
not authorized or permitted to hold title to real property in the state where
the REO Property is located, or would be adversely affected under the "doing
business" or tax laws of such state by so holding title, the deed or
certificate of sale shall be taken in the name of such Person or Persons as
shall be consistent with an Opinion of Counsel obtained by the Company from
any attorney duly licensed to practice law in the state where the REO Property
is located. The Person or Persons holding such title other than the Purchaser
shall acknowledge in writing that such title is being held as nominee for the
Purchaser.

     The Company shall manage, conserve, protect and operate each REO Property
for the Purchaser solely for the purpose of its prompt disposition and sale.
The Company, either itself or through an agent selected by the Company, shall
manage, conserve, protect and operate the REO Property in the same manner that
it manages, conserves, protects and operates other foreclosed property for its
own account, and in the same manner that similar property in the same locality
as the REO Property is managed. The Company shall attempt to sell the same
(and may temporarily rent the same for a period not greater than one year,
except as otherwise provided below) on such terms and conditions as the
Company deems to be in the best interest of the Purchaser.

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

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

     The Company shall also maintain on each REO Property fire and hazard
insurance with extended coverage in an amount which is at least equal to the
maximum insurable value of the improvements which are part of such property,
liability insurance and, to the extent required and available under the Flood
Disaster Protection Act of 1973, as amended, flood insurance in the amount
required above.

     The disposition of REO Property shall be carried out by the Company at
such price, and upon such terms and conditions, as the Company deems to be in
the best interests of the Purchaser. The proceeds of sale of the REO Property
shall be promptly deposited in the Custodial Account. As soon as practical
thereafter, the expenses of such sale shall be paid and the Company shall
reimburse itself for any related unreimbursed Servicing Advances, unpaid
Servicing Fees and unreimbursed Monthly Advances made pursuant to Section
5.03, and on the Remittance Date immediately following the Principal
Prepayment Period in which such sale proceeds are received the net cash
proceeds of such sale remaining in the Custodial Account shall be distributed
to the Purchaser.

     The Company shall withdraw from the Custodial Account funds necessary for
the proper operation, management and maintenance of each REO Property,
including the cost of maintaining any hazard insurance pursuant to Section
4.10 and the fees of any managing agent of the Company, a Subservicer, or the
Company itself. The REO management fee shall be an amount that is reasonable
and customary in the area where the Mortgaged Property is located. The Company
shall make monthly distributions on each Remittance Date to the Purchaser of
the net cash flow from the REO Property (which shall equal the revenues from
such REO Property net of the expenses described in this Section 4.15 and of
any reserves reasonably required from time to time to be maintained to satisfy
anticipated liabilities for such expenses).

     Section 4.16. Real Estate Owned Reports.

     Together with the statement furnished pursuant to Section 5.02, the
Company shall furnish to the Purchaser on or before the Remittance Date each
month a statement with respect to any REO Property covering the operation of
such REO Property for the previous month and the Company's efforts in
connection with the sale of such REO Property and any rental of such REO
Property incidental to the sale thereof for the previous month. That statement
shall be accompanied by such other information as the Purchaser shall
reasonably request.

     Sction 4.17. Liquidation Reports.

     Upon the foreclosure sale of any Mortgaged Property or the acquisition
thereof by the Purchaser pursuant to a deed in lieu of foreclosure, the
Company shall submit to the Purchaser a liquidation report with respect to
such Mortgaged Property.

         Section 4.18.  Notification of Adjustments.

     With respect to each Mortgage Loan, the Company shall adjust the Mortgage
Interest Rate on the related Interest Rate Adjustment Date in compliance with
requirements of applicable law and the related Mortgage and Mortgage Note. The
Company shall execute and deliver any and all necessary notices required under
applicable law and the terms of the related Mortgage Note and Mortgage
regarding the Mortgage Interest Rate adjustments. The Company shall promptly,
upon written request therefor, deliver to the Purchaser such notifications and
any additional applicable data regarding such adjustments and the methods used
to calculate and implement such adjustments. Upon the discovery by the Company
or the receipt of notice from the Purchaser that the Company has failed to
adjust a Mortgage Interest Rate in accordance with the terms of the related
Mortgage Note, the Company shall immediately deposit in the Custodial Account
from its own funds the amount of any interest loss or deferral caused to the
Purchaser thereby.

     Section 4.19. Reports of Foreclosures and Abandonments of Mortgaged
Property.

     Following the foreclosure sale or abandonment of any Mortgaged Property,
the Company shall report such foreclosure or abandonment as required pursuant
to Section 6050J of the Code.

                                   ARTICLE V

                             PAYMENTS TO PURCHASER

     Section 5.01. Remittances.

     On each Remittance Date the Company shall remit by wire transfer of
immediately available funds to the Purchaser the sum of (a) all amounts
deposited in the Custodial Account as of the close of business on the
Determination Date (net of charges against or withdrawals from the Custodial
Account pursuant to Section 4.05 ), (b) all amounts, if any, which the Company
is obligated to deposit into the Custodial Account pursuant to Section 5.03,
and (c) any amounts payable with respect to Qualified Substitute Mortgage
Loans, but not including, (i) any amounts attributable to Principal
Prepayments received after the immediately preceding Principal Prepayment
Period, (ii) any Liquidation Proceeds and Insurance Proceeds received after
the immediately preceding Prepayment Period, and (iii) any amounts
attributable to Monthly Payments collected but due on a Due Date or Dates
subsequent to the first day of the month of such Remittance Date, all of which
amounts together with any additional interest required to be deposited into a
Custodial Account in connection with a Principal Prepayment in accordance with
Section 4.04(viii), shall be remitted on the next succeeding Remittance Date.


     With respect to any remittance received by the Purchaser after the second
Business Day following the Remittance Date on which such payment was due, the
Company shall pay to the Purchaser interest on any such late payment at an
annual rate equal to the Prime Rate, adjusted as of the date of each change,
plus three (3) percentage points, but in no event greater than the maximum
amount permitted by applicable law. Such interest shall be deposited in the
Custodial Account by the Company on the date such late payment is made and
shall cover the period commencing with the day following such second Business
Day and ending with the Business Day on which such payment is made, both
inclusive. Such interest shall be remitted along with the distribution payable
on the next succeeding Remittance Date. The payment by the Company of any such
interest shall not be deemed an extension of time for payment or a waiver of
any Event of Default by the Company.

     Section 5.02. Statements to Purchaser.

     Not later than the Remittance Date, the Company shall furnish to the
Purchaser a Monthly Remittance Advice, with a trial balance report attached
thereto, in the form of Exhibit F annexed hereto as to the preceding
remittance and the period ending on the preceding Determination Date.

     In addition, not more than sixty (60) days after the end of each calendar
year, the Company shall furnish to each Person who was a Purchaser at any time
during such calendar year an annual statement in accordance with the
requirements of applicable federal income tax law as to the aggregate of
remittances for the applicable portion of such year.

     Such obligation of the Company shall be deemed to have been satisfied to
the extent that substantially comparable information shall be provided by the
Company pursuant to any requirements of the Code as from time to time are in
force.

     The Company shall prepare and file any and all tax returns, information
statements or other filings relating to the period of time prior to the sale
of the Mortgage Loans by the Company to the Purchaser required to be delivered
to any governmental taxing authority pursuant to any applicable law with
respect to the Mortgage Loans. In addition, the Company shall provide the
Purchaser with such information concerning the Mortgage Loans as is necessary
for the Purchaser to prepare its federal income tax returns.

     Section 5.03. Monthly Advances by Company.

     On the Business Day immediately preceding each Remittance Date, the
Company shall deposit in the Custodial Account from its own funds an amount
equal to all Monthly Payments (with interest adjusted to the Mortgage Loan
Remittance Rate) which were due on the Mortgage Loans during the applicable
Due Period and which were delinquent at the close of business on the
immediately preceding Determination Date or which were deferred pursuant to
Section 4.01. The Company's obligation to make such Monthly Advances as to any
Mortgage Loan will continue (i) through the last Monthly Payment due prior to
the payment in full of the Mortgage Loan, (ii) through the last Remittance
Date prior to the Remittance Date for the distribution of all Liquidation
Proceeds or other payments or recoveries (including Insurance Proceeds and
Condemnation Proceeds) with respect to the Mortgage Loans or (iii) until the
Company deems a future advance to be a Nonrecoverable Advance, whichever of
(i) (ii) or (iii) occurs first.

                                  ARTICLE VI

                         GENERAL SERVICING PROCEDURES

     Section 6.01. Transfers of Mortgaged Property.

     The Company shall use its best efforts to enforce any "due-on-sale"
provision contained in any Mortgage or Mortgage Note and to deny assumption by
the person to whom the Mortgaged Property has been or is about to be sold
whether by absolute conveyance or by contract of sale, and whether or not the
Mortgagor remains liable on the Mortgage and the Mortgage Note. When the
Mortgaged Property has been conveyed by the Mortgagor, the Company shall, to
the extent it has knowledge of such conveyance, exercise its right to
accelerate the maturity of such Mortgage Loan under the "due-on-sale" clause
applicable thereto; provided, however, that the Company shall not exercise
such rights if prohibited by law from doing so.

     If the Company reasonably believes it is unable under applicable law to
enforce such "due-on-sale" clause, the Company shall enter into (i) an
assumption and modification agreement with the person to whom such property
has been conveyed, pursuant to which such person becomes liable under the
Mortgage Note and the original Mortgagor remains liable thereon or (ii) in the
event the Company is unable under applicable law to require that the original
Mortgagor remains liable under the Mortgage Note and the Company has the prior
consent of the primary mortgage guaranty insurer, a substitution of liability
agreement with the purchaser of the Mortgaged Property pursuant to which the
original Mortgagor is released from liability and the purchaser of the
Mortgaged Property is substituted as Mortgagor and becomes liable under the
Mortgage Note. If an assumption fee is collected by the Company for entering
into an assumption agreement, a portion of such fee, up to an amount equal to
one-half of one percent (0.5%) of the outstanding principal balance of the
related Mortgage Loan, will be retained by the Company as additional servicing
compensation, and any portion thereof in excess of one-half of one percent
(0.5%) shall be deposited in the Custodial Account for the benefit of the
Purchaser. In connection with any such assumption, neither the Mortgage
Interest Rate borne by the related Mortgage Note, the term of the Mortgage
Loan nor the outstanding principal amount of the Mortgage Loan shall be
changed.

     To the extent that any Mortgage Loan is assumed, the Company shall
inquire diligently into the creditworthiness of the proposed transferee, and
shall use the Company's Summary of Underwriting Guidelines attached hereto as
Exhibit A-1. If the credit of the proposed transferee does not meet such
underwriting criteria, the Company diligently shall, to the extent permitted
by the Mortgage or the Mortgage Note and by applicable law, accelerate the
maturity of the Mortgage Loan.

     Section 6.02. Satisfaction of Mortgages and Release of Mortgage Files.

     Upon the payment in full of any Mortgage Loan, or the receipt by the
Company of a notification that payment in full will be escrowed in a manner
customary for such purposes, the Company shall notify the Purchaser in the
Monthly Remittance Advice as provided in Section 5.02, and may request the
release of any Mortgage Loan Documents.

     Except as permitted pursuant to Section 4.01, if (i) the Company
satisfies or releases a Mortgage without first having obtained payment in full
of the indebtedness secured by the Mortgage or notification that payment in
full will be escrowed in a manner customary for such purposes or (ii) should
the Company otherwise prejudice any rights the Purchaser may have under the
mortgage instruments, upon written demand of the Purchaser, the Company shall
repurchase the related Mortgage Loan at the Repurchase Price by deposit
thereof in the Custodial Account within two (2) Business Days of receipt of
such demand by the Purchaser. The Company shall maintain the Fidelity Bond and
Errors and Omissions Insurance Policy as provided for in Section 4.12 insuring
the Company against any loss it may sustain with respect to any Mortgage Loan
not satisfied in accordance with the procedures set forth herein.

     Section 6.03. Servicing Compensation.

     As compensation for its services hereunder, the Company shall be entitled
to withdraw from the Custodial Account or to retain from interest payments on
the Mortgage Loans the amount of its Servicing Fee. The Servicing Fee shall be
payable monthly and shall be computed on the basis of the same unpaid
principal balance and for the same period with respect to which any related
interest payment on a Mortgage Loan is computed. The Servicing Fee shall be
payable only at the time of and with respect to those Mortgage Loans for which
payment is in fact made of the entire amount of the Monthly Payment. The
obligation of the Purchaser to pay the Servicing Fee is limited to, and
payable solely from, the interest portion of such Monthly Payments collected
by the Company. The aggregate of the Servicing Fees for any months with
respect to the Mortgage Loans shall be reduced by any amount payable by the
Company with respect to such month pursuant to Section 4.04(viii).

     Additional servicing compensation in the form of assumption fees, to the
extent provided in Section 6.01, and late payment charges shall be retained by
the Company to the extent not required to be deposited in the Custodial
Account. The Company shall be required to pay all expenses incurred by it in
connection with its servicing activities hereunder and shall not be entitled
to reimbursement thereof except as specifically provided for herein.

     Section 6.04. Annual Statement as to Compliance.

     The Company shall deliver to the Purchaser, on or before March 31st each
year beginning March 31, 1999, an Officer's Certificate, stating that (i) a
review of the activities of the Company during the preceding calendar year and
of performance under this Agreement has been made under such officer's
supervision, and (ii) the Company has complied fully with the provisions of
Article II and Article IV, and (iii) to the best of such officer's knowledge,
based on such review, the Company has fulfilled all of its obligations under
this Agreement throughout such year, or, if there has been a default in the
fulfillment of any such obligation, specifying each such default known to such
officer and the nature and status thereof and the action being taken by the
Company to cure such default.

     Section 6.05. Annual Independent Public Accountants' Servicing Report.

     On or before March 31st of each year beginning March 31, 1999, the
Company, at its expense, shall cause a firm of independent public accountants
which is a member of the American Institute of Certified Public Accountants to
furnish a statement to the Purchaser to the effect that such firm has examined
certain documents and records relating to the servicing of the Mortgage Loans,
on the basis of such examination conducted substantially in compliance with
the Single Attestation Program for Mortgage Bankers, nothing has come to their
attention which would indicate that such servicing has not been conducted in
compliance therewith, except for (i) such exceptions as such firm shall
believe to be immaterial, and (ii) such other exceptions as shall be set forth
in such statement.

     Section 6.06. Right to Examine Company Records.

     The Purchaser shall have the right to examine and audit any and all of
the books, records, or other information of the Company, whether held by the
Company or by another on its behalf, with respect to or concerning this
Agreement or the Mortgage Loans, during business hours or at such other times
as may be reasonable under applicable circumstances, upon reasonable advance
notice.

                                  ARTICLE VII

                             COMPANY TO COOPERATE

     Section 7.01. Provision of Information.

     During the term of this Agreement, the Company shall furnish to the
Purchaser such periodic, special, or other reports or information and copies
or originals of any documents contained in the Servicing File for each
Mortgage Loan, whether or not provided for herein, as shall be necessary,
reasonable, or appropriate with respect to the Purchaser, any regulatory
requirement pertaining to the Purchaser or the purposes of this Agreement. All
such reports, documents or information shall be provided by and in accordance
with all reasonable instructions and directions which the Purchaser may give.

     The Company shall execute and deliver all such instruments and take all
such action as the Purchaser may reasonably request from time to time, in
order to effectuate the purposes and to carry out the terms of this Agreement.

         Section 7.02. Financial Statements;  Servicing Facilities.

     The Company may make available to a prospective Purchaser a Consolidated
Statement of Operations of Mellon Bank Corporation for the most recently
completed five fiscal years for which such a statement is available, as well
as a Consolidated Statement of Condition at the end of the last two fiscal
years covered by such Consolidated Statement of Operations. The Company also
shall make available any comparable interim statements to the extent any such
statements have been prepared by or on behalf of the Company (and are
available upon request to members or stockholders of the Company or to the
public at large). Upon Purchaser's request, the Company shall furnish promptly
to the Purchaser copies of the statement specified above.

     Upon Purchaser's request, the Company also shall make available to
Purchaser a knowledgeable financial or accounting officer for the purpose of
answering questions respecting recent developments affecting the Company or
the financial statements of the Company.

                                 ARTICLE VIII

                                  THE COMPANY

     Section 8.01. Third Party Claims.

     The Company immediately shall notify the Purchaser if a claim is made by
a third party with respect to this Agreement or the Mortgage Loans, assume
(with the prior written consent of the Purchaser) the defense of any such
claim and pay all expenses in connection therewith, including reasonable and
necessary counsel fees, and promptly pay, discharge and satisfy any judgment
or decree which may be entered against it or the Purchaser in respect of such
claim. The Company shall follow any written instructions received from the
Purchaser in connection with such claim. The Purchaser promptly shall
reimburse the Company for all amounts advanced by it pursuant to the preceding
sentence except when the claim is in any way related to the Company's
indemnification pursuant to Section 3.03 and the Purchaser has notified the
Company of such third party claim as provided herein, or to the failure of the
Company to service and administer the Mortgage Loans in strict compliance with
the material terms of this Agreement and such failure of the Company is not
attributable to acts or omissions by the Purchaser. In the event of claims
relating to the Company's indemnification pursuant to Section 3.03, the
Purchaser immediately shall notify the Company of any claim by a third party.

     Section 8.02. Merger or Consolidation of the Company.

     The Company shall obtain and preserve its qualification to do business as
a foreign corporation in each jurisdiction in which such qualification is or
shall be necessary to protect the validity and enforceability of this
Agreement or any of the Mortgage Loans and to perform its duties under this
Agreement.

     Any person into which the Company may be merged or consolidated, or any
corporation resulting from any merger, conversion or consolidation to which
the Company shall be a party, or any Person succeeding to the business of the
Company, shall be the successor of the Company hereunder, without the
execution or filing of any paper or any further act on the part of any the
parties hereto, anything herein to the contrary notwithstanding; provided,
however, that the successor or surviving Person shall be an institution (i)
whose deposits are insured by the FDIC through the BIF or the SAIF, (ii) which
is or is affiliated with a FNMA-approved servicer in good standing, and (iii)
has a net worth of at least $15 million.

     Section 8.03. Limitation on Liability of Company and Others.

     Neither the Company nor any of the parents, affiliates, subsidiaries,
directors, officers, employees or agents of the Company shall be under any
liability to the Purchaser 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
Company or any such Person against any breach of warranties or representations
made herein, or failure to perform its obligations in strict compliance with
any standard of care set forth in this Agreement, or any liability which would
otherwise be imposed by reason of any breach of the terms and conditions of
this Agreement. The Company and any parent, affiliate, subsidiary, director,
officer, employee or agent of the Company 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 Company shall not be under any
obligation to appear in, prosecute or defend any legal action which is not
incidental to its duties to service the Mortgage Loans in accordance with this
Agreement and which in its opinion may involve it in any expense or liability;
provided, however, that the Company may, with the consent of the Purchaser,
undertake any such action which it may deem necessary or desirable in respect
to this Agreement and the rights and duties of the parties hereto. In such
event, the Company shall be entitled to reimbursement from the Purchaser of
the reasonable legal expenses and costs of such action.

     Section 8.04. Limitation on Resignation and Assignment by Company.

     The Purchaser has entered into this Agreement with the Company and any
subsequent Purchaser will purchase the Mortgage Loans in reliance upon the
representations as to the adequacy of its servicing facilities, plant,
personnel, records and procedures, its integrity, reputation and financial
standing, and the continuance thereof. Therefore, the Company shall not assign
this Agreement or the servicing hereunder nor shall it delegate its rights or
duties hereunder or any portion hereof (to other than a Subservicer) or sell
or otherwise dispose of all or substantially all of its property or assets
without the prior written consent of the Purchaser (which consent shall be
granted or withheld in the sole discretion of the Purchaser) except that the
Company may assign this Agreement to a successor, parent, or affiliated entity
without the prior written consent of the Purchaser in accordance with Section
8.02.

     The Company shall not resign from the obligations and duties hereby
imposed on it except by mutual consent of the Company and the Purchaser or
upon the determination that its duties hereunder are no longer permissible
under applicable law and such incapacity cannot be cured by the Company by
reasonable means. Any such determination permitting the resignation of the
Company shall be evidenced by an Opinion of Counsel to such effect delivered
to the Purchaser, which Opinion of Counsel shall be in form and substance
acceptable to the Purchaser. No such resignation shall become effective unless
(i) the Company also resigns from the Amended and Restated Mortgage Loan Sale,
Warranties and Servicing Agreement, dated as of April 1, 1998 (the "Second
Sale and Servicing Agreement") between the Company and the Purchaser, which
amends and restates the Mortgage Loan Sale, Warranties and Servicing, dated as
of April 1, 1998 between the Company and the Purchaser and (ii) until a
successor shall have assumed the Company's responsibilities and obligations
hereunder and under the Second Sale and Servicing Agreement in the manner
provided in Section 11.01 in each of this Agreement and the Second Sale and
Servicing Agreement.

     Without in any way limiting the generality of this Section 8.04, and
except as otherwise permitted under this Agreement, in the event that the
Company either shall assign this Agreement or the servicing responsibilities
hereunder or delegate its duties hereunder or any portion thereof (to other
than a Subservicer) or sell or otherwise dispose of all or substantially all
of its property or assets, without the prior written consent of the Purchaser,

          (ix) an Event of Default (as defined in the Second Sale and
Servicing Agreement) on the part of the Company.

     In each and every such case, so long as an Event of Default shall not
have been remedied (within, if applicable, the period specified), in addition
to whatsoever rights the Purchaser may have at law or equity to damages,
including injunctive relief and specific performance, the Purchaser, by notice
in writing to the Company, may terminate all the rights and obligations of the
Company under this Agreement and in and to the Mortgage Loans and the proceeds
thereof.

     Upon receipt by the Company of such written notice, all authority and
power of the Company under this Agreement, whether with respect to the
Mortgage Loans or otherwise, shall pass to and be vested in the successor
appointed pursuant to Section 11.01. Upon written request from the Purchaser,
the Company shall prepare, execute and deliver to the successor entity
designated by the Purchaser any and all documents and other instruments, place
in such successor's possession all Mortgage Files, and do or cause to be done
all other acts or things necessary or appropriate to effect the purposes of
such notice of termination, including but not limited to the transfer and
endorsement or assignment of the Mortgage Loans and related documents, at the
Company's sole expense. The Company shall cooperate with the Purchaser and
such successor in effecting the termination of the Company's responsibilities
and rights hereunder, including without limitation, the transfer to such
successor for administration by it of all cash amounts which shall at the time
be credited by the Company to the Custodial Account or Escrow Account or
thereafter received with respect to the Mortgage Loans.

     Section 9.02. Waiver of Defaults.

     By a written notice, the Purchaser may waive any default by the Company
in the performance of its obligations hereunder and its consequences. Upon any
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.

                                   ARTICLE X

                                  TERMINATION

     Section 10.01. Termination.

     This Agreement shall terminate upon either: (i) the later of the final
payment or other liquidation (or any advance with respect thereto) of the last

consent of the Company and the Purchaser in writing.

                                  ARTICLE XI

                           MISCELLANEOUS PROVISIONS

     Section 11.01.  Successor to Company.

     Prior to termination of the Company's responsibilities and duties under
this Agreement pursuant to Sections 8.04, 9.01 or 10.01 (ii) the Purchaser
shall (i) succeed to and assume all of the Company's responsibilities, rights,
duties and obligations under this Agreement, or (ii) appoint a successor
having the characteristics set forth in clauses (i) through (iii) of Section
8.02 and which shall succeed to all rights and assume all of the
responsibilities, duties and liabilities of the Company under this Agreement
prior to the termination of Company's responsibilities, duties and liabilities
under this Agreement. In connection with such appointment and assumption, the
Purchaser may make such arrangements for the compensation of such successor
(not to exceed the Servicing Fee) out of payments on Mortgage Loans as it and
such successor shall agree. In the event that the Company's duties,
responsibilities and liabilities under this Agreement should be terminated
pursuant to the aforementioned sections, the Company shall discharge such
duties and responsibilities during the period from the date it acquires
knowledge of such termination until the effective date thereof with the same
degree of diligence and prudence which it its obligated to exercise under this
Agreement, and shall take no action whatsoever that might impair or prejudice
the rights or financial condition of its successor. The resignation or removal
of the Company pursuant to the aforementioned sections shall not become
effective until a successor shall be appointed pursuant to this Section 11.01
and shall in no event relieve the Company of the representations and
warranties made pursuant to Sections 3.01 and 3.02 and the remedies available
to the Purchaser under Section 3.03, it being understood and agreed that the
provisions of such Sections 3.01 and 3.02 shall be applicable to the Company
notwithstanding any such sale, assignment, resignation or termination of the
Company, or the termination of this Agreement.

     Any successor appointed as provided herein shall execute, acknowledge and
deliver to the Company and to the Purchaser an instrument accepting such
appointment, wherein the successor shall make the representations and
warranties set forth in Section 3.01, except for subsections (h), (i) and (j)
thereof, whereupon such successor shall become fully vested with all the
rights, powers, duties, responsibilities, obligations and liabilities of the
Company, with like effect as if originally named as a party to this Agreement.
Any termination or resignation of the Company or termination of this Agreement
pursuant to Section 8.04, 9.01 or 10.01 shall not affect any claims that any
Purchaser may have against the Company arising out of the Company's actions or
failure to act prior to any such termination or resignation.

     The Company shall deliver promptly to the successor servicer the funds in
the Custodial Account, REO Account and Escrow Account and all Mortgage Files
and related documents and statements held by it hereunder and the Company
shall account for all funds and shall execute and deliver such instruments and
do such other things as may reasonably be required to more fully and
definitively vest in the successor all such rights, powers, duties,
responsibilities, obligations and liabilities of the Company.

         Section 11.02.  Amendment.

     Capitalized terms used in this Section 11.02 but not defined in this
Agreement shall have the meanings assigned to them in the Trust Agreement.

          (a) This Agreement may be amended from time to time by the Company
and the Purchaser (ii) to cure any ambiguity, (ii) 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 the
Trust Agreement, nor shall such amendment effected pursuant to clause (iii) of
such sentence adversely affect in any material respect the interest of any
Holder of any Certificates issued by the Trust. Prior to entering into any
amendment pursuant to this paragraph, the Purchaser 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 of
Certificates, if the Purchaser 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
Company and the Purchaser with the consent of the Holders of not less that
66K% of the Class Certificate Principal Amount (or Aggregate Notional Amount)
of each Class of Certificates affected thereby for the purpose of adding any
provisions to or changing in any manner or deleting any of the provisions of
this Agreement or of modifying in any manner the rights of the Holders (except
as such additions, changes, deletions or modifications may be permitted under
Section 11.02(a) above); provided, however, that no such amendment shall be
made unless the Purchaser receives an Opinion of Counsel, at the expense of
the party requesting the change, that such change will not adversely affect
the status of any REMIC created pursuant to the Trust Agreement as a REMIC or
cause a tax to be imposed on any such REMIC.

          Section 11.03. Governing Law.

          This Agreement shall be governed by and construed in accordance with
the laws of the Commonwealth of Massachusetts and the obligations, rights and
remedies of the parties hereunder shall be determined in accordance with such
laws.

          Section 11.04. Duration of Agreement.

          This Agreement shall continue in existence and effect until
terminated as herein provided, except that Sections 3.01, 3.02, 8.01 and 8.03
shall survive such termination. This Agreement shall continue notwithstanding
transfers of the Mortgage Loans by the Purchaser.

shall in no way affect the validity or enforceability of the other provisions

respective successors and permitted assigns.

entire agreement between the parties hereto with respect to the transactions

and that provision of the Purchase Price and Terms Letter shall survive for
the exclusive purpose of such cross-reference. The provisions of this
Agreement shall govern in any conflict between the terms of this Agreement and
the Purchase Price and Terms Letter.

     Section 11.10. Assignment by Purchaser.

     The Purchaser shall have the right, without the consent of the Company
but subject to the limit set forth in Section 2.02 hereof, to assign, in whole
or in part, its interest under this Agreement with respect to some or all of
the Mortgage Loans, and designate any person to exercise any rights of the
Purchaser hereunder, and the assignee or designee shall accede to the rights
and obligations hereunder of the Purchaser with respect to such Mortgage
Loans. All references to the Purchaser in this Agreement shall be deemed to
include its assignee or designee and any subsequent assignee, specifically
including the Trustee.

     Section 11.11.  No Solicitation.

     From and after the Closing Date, the Company agrees that it will not take
any action or permit or cause any action to be taken by any of its agents or
affiliates, or by any independent contractors on the Company's behalf, to
personally, by telephone or mail, solicit the borrower or obligor under any
Mortgage Loan for purposes relating to the marketing of the Company's first

part, without the prior written consent of the Purchaser, its successors and
assigns. It is understood and agreed that all rights and benefits relating to

interest in and to the list of such Mortgagors and data relating to their
Mortgages (including insurance renewal dates) shall be transferred to the

action to undermine these rights and benefits. Notwithstanding the foregoing,
it is understood and agreed that general promotions undertaken by the Company
or any affiliate of the Company, including, without limitation, mass mailings

     Section 11.12. Reconstitution.

     The Company understands and agrees that it is the intent of the Purchaser
to securitize the Mortgage Loans (i.e., to form a trust and to issue
securities evidencing interests therein). The Company agrees to review and
adhere to the terms of any agreements that may be required to facilitate such
securitization and to provide and execute such certificates, Opinions of
Counsel and other documents as may be necessary to facilitate such
securitization, it being understood that any such agreements and other
documents will not impose upon the Company any obligations more burdensome

fees and other costs incurred in connection with such securitization.

Letter shall survive the execution of this Agreement and shall remain in

                           _____________ ____,199__



Lehman Capital, A Division of
   Lehman Brothers Holdings Inc.
3 World Financial Center
New York, NY 10285-1200

Dear Ladies and Gentlemen:

     I am Deputy General Counsel of and counsel for Boston Safe Deposit and
Trust Company (the "Seller"), in connection with the sale (the "Sale") by the
Seller of a portfolio of loans secured by residential real estate and shares
of cooperative associations (the "Loans") to Lehman Capital, A Division of
Lehman Brothers Holdings Inc. ("the Purchaser") pursuant to a Mortgage Loan
Sale, Warranties and Servicing Agreement dated as of _____________ ___, ____,
by and between the Seller and the Purchaser. Capitalized terms used but not
defined herein have the meanings ascribed to them in the Agreement.

     In connection with rendering this opinion, I have examined originals, or
copies identified to my satisfaction as being true copies of originals, of the
following, among other things:

     (a)  the Mortgage Loan Sale, Warranties and Servicing Agreement;

     (b)  the Additional Pledged Collateral Custodial Agreement by and among
          the Seller, the Purchaser and [ ] ("the Custodian");

     (c)  the form of Assignment of Mortgage;

     (d)  the form of endorsement of the Mortgage Notes;

     (e)  the Charter and By-laws of the Seller; and,

     (f)  such other documents, records and papers as we have deemed necessary
          and relevant as a basis for this opinion.

     For the purposes of the opinions expressed below, I have assumed (i) the
genuineness of all signatures on original documents or instruments; (ii) the
authenticity of all documents or instruments submitted to me as originals,
(iii) the conformity to originals of all documents or instruments submitted to
me as copies; (iv) the due authorization, execution and delivery of all
documents where due authorization, execution and delivery are requisite to the
effectiveness thereof (other than the authorization, execution and delivery by
the Seller of the Agreement, as to which my opinions are expressed below); (v)
that, immediately prior to the transfer of any Loan to the Purchaser pursuant
to the Agreement, with respect to such Loan, (A) the Seller was the holder and
named payee of the Note, (B) the Seller was the mortgagee or beneficiary, as
applicable, under each related Security Instrument, and (C) the Seller was the
owner of such Loan free and clear of any and all liens, claims, encumbrances,
participation interests, equities, pledges, charges, security or other
interests of any nature; (vi) that each Note corresponding to each Loan has
been endorsed by the Seller using the form of endorsement attached hereto and
each Note so endorsed has been delivered to the Purchaser on or before the
date hereof; (vii) that the Purchaser is acquiring the Loans in good faith for
value without notice that they are overdue or have been dishonored or of any
defense against or claim to the Loans or any interest therein on the part of
any person; (viii) that there is no evidence on any of the Loan Documents of
any interest contrary to the Seller's interests under the Agreement; (ix) that
the Seller is solvent and will not be rendered insolvent by the sale of the
portfolio of Loans; and, (x) that the Seller has received payment of
reasonably equivalent value for the Loans. I have no actual knowledge that any
of the foregoing assumptions is incorrect. I also have relied to the extent I
deem proper upon written statements and certificates of public officials and,
as to various matters of fact relevant to the opinions expressed herein, I
have relied upon certificates and statements of officers of the Seller.

     On the basis of the foregoing examination, statements and assumptions and
in reliance thereon and upon consideration of applicable law, I am of the
opinion that:

     (1) The Seller is a Massachusetts trust company, duly organized, validly
existing, and in good standing under the laws of the Commonwealth of
Massachusetts and is duly authorized to transact its business.

     (2) The Seller has the requisite corporate power to execute and deliver
the Agreement and to consummate the transactions contemplated thereby. The
execution and delivery of the Agreement by the Seller and the consummation of
the transactions contemplated thereby have been duly authorized by all
necessary corporate action on the part of the Seller. The Agreement has been
duly executed and delivered by the Seller and, assuming due authorization,
execution and delivery by Purchaser and prior satisfaction of all conditions
to the obligations of each of the parties under the Agreement (or a valid
waiver thereof by such parties, as applicable), the Agreement constitutes the
legal, valid, and binding obligation of the Seller enforceable in accordance
with its terms subject only to the exceptions set forth below, and Seller has
all power, authority and right to perform and observe the terms and conditions
of such instruments.

     (3) The execution and delivery of the Agreement by the Seller does not,
and the performance of the Agreement by the Seller will not, (a) result in a
breach of or violate the Charter or By-laws of the Seller, (b) violate (A) any
statute, law, rule or regulation, or (B) to the best of my knowledge, any
order, judgment, award, administrative interpretation, injunction, writ, or
decree or the like of any court or government authority, or (C) to the best of
my knowledge, conflict with or violate any agreement, permit, license, or
other governmental authorization or approval necessary for the purchase by the
Seller of the Loans, the effect of which breach, conflict or violation would
be material and adverse to the rights of the Purchaser under the Agreement or
to the Loans. No regulatory approvals or consents are required under
Massachusetts or federal law or regulation with respect to Seller's
consummation of the transactions between Purchaser and Seller contemplated by
the Agreement.

     (4) To the best of my knowledge, there are no actions, suits,
proceedings, or governmental investigations or inquiries pending or threatened
against the Seller seeking to prevent or that, if successful, would prevent
the consummation of the transactions contemplated by the Agreement.

     (5) The Mortgages have been duly assigned and the Mortgage Notes have
been duly endorsed by a duly authorized officer of the Company as provided in
the Custodial Agreement.

     The opinion set forth in the last sentence of paragraph (2) above to the
effect that the Agreement is enforceable against Seller in accordance with its
terms, is subject to the following exceptions:

     a. Such enforceability may be limited by bankruptcy, insolvency,
receivership, conservatorship, reorganization or other similar laws now or
hereafter in effect relating to or affecting creditor's rights.

     b. Such enforceability may be limited by general equitable principles,
including, without limitation, concepts of materiality, reasonableness, good
faith and fair dealing, and the possible unavailability of specific
performance or injunctive relief, regardless of whether such enforceability is
considered in a proceeding in equity or at law.

     I hereby advise your that the opinions expressed herein are limited to
matters of federal law and the law of the Commonwealth of Massachusetts and do
not purport to cover any matters as to which any laws of any other
jurisdiction are applicable. Insofar as the opinions expressed herein are
limited to transactions between the Seller and the Purchaser, except for the
opinion I express in paragraph (5) above, I express no opinion regarding any
transaction(s) between Seller or Purchaser and any Obligor(s) evidenced by
loan applications, Notes, Mortgages, disclosures, notices or any other
instrument or documents entered into or exchanged between the Seller or
Purchaser and the Obligor(s). I am not assuming any obligation to revise or
supplement the opinions expressed above should such laws be changed by
legislative action, judicial decision, or otherwise.

     This opinion is rendered to you as the Purchaser named in the Agreement
solely in connection with the transactions contemplated therein and may not be
used or relied upon by any other person or for any other purpose without our
express prior written consent.

                                         Respectfully submitted,

                                          Marilyn K. Kolb
                                          Deputy General Counsel


  


                                   EXHIBIT J

                    FORM OF OPINION OF PURCHASER'S COUNSEL

Boston Safe Deposit and Trust Company
One Boston Place
Boston, MA 02108

Dear Ladies and Gentlemen:

     I am counsel for Lehman Capital, A Division of Lehman Brothers Holdings
Inc. (the "Purchaser"), in connection with the sale (the "Sale") by Boston
Safe Deposit and Trust Company ("Seller") of a portfolio of loans secured by
residential real estate and shares of cooperative associations (the "Loans")
to Purchaser pursuant to a Mortgage Loan Sale, Warranties and Servicing
Agreement dated as of _________________ ___, _____, by and between the Seller
and the Purchaser. Capitalized terms used but not defined herein have the
meanings ascribed to them in the Agreement.

     In connection with rendering this opinion, I have examined originals, or
copies identified to my satisfaction as being true copies of originals, of the
following, among other things:

     (a)   the Agreement and all exhibits and schedules thereto; and

     (b)   the Charter and By-laws of the Purchaser.

     For the purposes of the opinions expressed below, I have assumed (i) the
genuineness of all signatures on original documents or instruments; (ii) the
authenticity of all documents or instruments submitted to me as originals,
(iii) the conformity to originals of all documents or instruments submitted to

documents where due authorization, execution and delivery are requisite to the

(v) that, immediately prior to the transfer of any Loan to the Purchaser
pursuant to the Agreement, with respect to such Loan, (A) the Seller was the
holder and named payee of the Note, (B) the Seller was the mortgagee or
beneficiary, as applicable, under each related Security Instrument, and (C)
the Seller was the owner of such Loan free and clear of any and all liens,

security or other interests of any nature; (vi) that each Note corresponding
to each Loan has been endorsed by the Seller using the form of endorsement
attached hereto and each Note so endorsed has been delivered to the Purchaser
on or before the date hereof; (vii) that the Purchaser is acquiring the Loans
in good faith for value without notice that they are overdue or have been
dishonored or of any defense against or claim to the Loans or any interest
therein on the part of any person; (viii) that there is no evidence on any of
the Loan Documents of any interest contrary to the Seller's interests under
the Agreement; (ix) that the Purchaser is solvent and will not be rendered
insolvent by the purchase of the portfolio of Loans, and (x) that the Seller
has received payment of reasonably equivalent value for the Loans. I have no
actual knowledge that any of the foregoing assumptions is incorrect. I also
have relied to the extent I deem proper upon written statements and
certificates of public officials and, as to various matters of fact relevant
to the opinions expressed herein, I have relied upon certificates and
statements of officers of the Purchaser.

     On the basis of the foregoing examination, statements and assumptions and
in reliance thereon and upon consideration of applicable law, I am of the
opinion that:

     (1)  The Purchaser is a [ ], duly organized, validly existing, and in good
standing under the laws of [ ].

     (2)  The Purchaser has the requisite corporate power to execute and
deliver the Agreement and to consummate the transactions contemplated thereby.
The execution and delivery of the Agreement by the Purchaser and the

(or a valid waiver thereof by such parties, as applicable), the Agreement
constitutes the legal, valid, and binding obligation of the Purchaser
enforceable in accordance with its terms subject only to the exceptions set
forth below.

     (3) The execution and delivery of the Agreement by the Purchaser does
not, and the performance of the Agreement by the Purchaser will not, (a)
result in a breach of or violate the Charter or By-laws of the Purchaser, (b)
violate (A) any statute, law, rule or regulation, or (B) to the best of my
knowledge, any order, judgment, award, administrative interpretation,
injunction, writ, or decree or the like of any court or government authority,
or (C) to the best of my knowledge, conflict with or violate any agreement,
permit, concession, grant, franchise, license, or other governmental
authorization or approval necessary for the purchase by the Purchaser of the
Loans, the effect of which breach, conflict or violation would be material and
adverse to the rights of the Purchaser under the Agreement or to the Loans. No
regulatory approvals or consents are required under federal law or regulation
with respect to Purchaser's consummation of the transactions between Purchaser
and Seller contemplated by the Agreement.

     (4) To the best of my knowledge, there are no actions, suits,
proceedings, or governmental investigations or inquiries pending or threatened
against the Purchaser seeking to prevent or that, if successful, would prevent
the consummation of the transactions contemplated by the Agreement.

     The opinion set forth in the last sentence of paragraph (2) above to the

its terms, is subject to the following exceptions:

     a. Such enforceability may be limited by bankruptcy, insolvency,

     I hereby advise your that the opinions expressed herein are limited to
matters of federal and [ ] law and do not purport to cover any matters as to
which any laws of any other jurisdiction are applicable. Insofar as the
opinions expressed herein are limited to transactions between the Seller and

into or exchanged between the Seller or Purchaser and the Obligor(s). I am not
assuming any obligation to revise or supplement the opinions expressed above
should such laws be changed by legislative action, judicial decision, or
otherwise.

     This opinion is rendered to you as the Seller named in the Agreement
solely in connection with the transactions contemplated therein and may not be
used or relied upon by any other person or for any other purpose without our
express prior written consent.

                                      Respectfully submitted,

          depositories or similar organizations in the U.S. or elsewhere, as
          required for the secure and efficient handling of the property and
          as Custodian in its sole discretion shall select;

               (b) collect all income earned by, and all distributions due to,
          the Additional Collateral, if any;

               (c) collect all proceeds from securities, certificates of
          deposit or other investments which may mature or be called;

               (d) attend to exchanges of securities, to deposits or exchanges

          so-called corporate actions which affect the Additional Collateral
          as directed by the Purchaser; and

               (e) upon the Purchaser's written instructions, deliver to any
          person, agent, financial institution, partnership, corporation or
          other designated recipient any or all of the Additional Collateral
          held under this Agreement.

     The Custodian shall have no duty or responsibility to manage or recommend
investments of the assets held by it hereunder or to initiate any purchase,
sale or other investment transaction in the absence of proper instructions (as
set forth in Section 5 below).

     Section 5. Directions and Instructions.

     All directions to Custodian from the Purchaser shall be in writing
(provided that Custodian may, in its discretion, accept oral directions
subject to confirmation in writing), and Custodian shall be fully protected in
acting in accordance therewith or for failing to act in the absence thereof.
The Purchaser shall certify to Custodian the names and specimen signatures of
persons authorized to act for the Purchaser in relation to Custodian.
Communications to Custodian shall be sent to its offices at One Boston Place,
Boston, Massachusetts 02108 or to such other address as Custodian shall
specify, and such communications shall be binding upon Custodian when received
by it.

     Notwithstanding anything herein to the contrary, Custodian shall be fully
protected in acting in accordance with directions with respect to securities
transactions (including without limitation the affirmation and/or confirmation
of such transactions) received by it through a system or arrangement for the
coordination of securities transaction settlements operated by Depository
Trust Company or by any central securities depository, securities clearing
organization or book entry system which serves to link investment managers,
securities brokers and custodian banks, pursuant to an agreement entered into
by Custodian and the Purchaser to the same extent as if the directions were in
writing.

     Section 6. Without Express Authority.

     The Custodian may, in its discretion and without express authority from
the Purchaser:

               (a) endorse for collection, in the name of the Purchaser,
          checks, drafts and other negotiable instruments; and

               (b) in general, attend to all non-discretionary details in
          connection with the sale, exchange, substitution, purchase, transfer
          and other dealings with the Additional Collateral of the Purchaser
          except as otherwise provided by proper instructions.

     Section 7. Standard of Care.

     The duties of Custodian shall only be those specifically undertaken
pursuant to this Agreement, and Custodian shall not be liable for an act or
omission of another person in carrying out any responsibility imposed upon
such person with respect to the Additional Collateral held under this
Agreement whether such responsibility is allocated to such other person by
this Agreement or pursuant to a procedure established in this Agreement or
otherwise. In performing its duties under this Agreement, Custodian shall
exercise the same care and diligence that it would devote to its own property
and shall be liable only for losses arising from its negligence or willful
misconduct.

     Section 8. Indemnification of Custodian.

     The Purchaser agrees to indemnify and hold harmless the Custodian and its
directors, officers, employees, agents and nominees from all taxes (except
taxes on the net income of the Custodian, its agents and its nominees),
charges, expenses, assessments, claims and liabilities (including reasonable
legal fees and expenses) incurred by any of them in connection with the
performance of this Agreement, except such as may arise from any negligent
action, negligent failure to act or willful misconduct on the part of the
indemnified entity.

     Section 9. Compensation of Custodian.

     Throughout the Term of this Agreement, as set forth in Section 14 below,
the Custodian shall perform its duties hereunder without compensation.
Thereafter, the Custodian shall be entitled to reimbursement of expenses
incurred in connection with any necessary transfer following notice of
termination or removal under Sections 11, 12 or 14.

     Section 10. Examination of Custodial Files.

     Upon reasonable prior notice to the Custodian, the Purchaser and its
agents, accounts, attorneys and auditors will be permitted during normal
business hours to examine the records relating to Additional Pledged
Collateral in the possession of or under the control of the Custodian relating
to any or all of the Mortgage Loans.

     Section 11. Removal of Custodian.

     Upon at least 45 days' prior written notice to the Custodian, and only
for cause, the Purchaser may remove and discharge the Custodian from the
performance of its duties under this Agreement. Having given notice of such
removal, the Purchaser promptly shall appoint a successor Custodian to act on
behalf of the Purchaser by written instrument, one original counterpart of
which instrument shall be delivered to the Custodian. Any termination by the
Purchaser shall be accompanied or followed promptly by proper instructions in
writing setting forth the names of the persons to whom the Custodian shall
deliver the Additional Collateral. The Custodian will deliver promptly the
Additional Collateral to the persons so specified, after deducting therefrom
any amounts which the Custodian is owed for services or reimbursement of
expenses hereunder. The Purchaser shall be responsible for the fees of the
successor Custodian.

     Section 12. Termination by Custodian.

     The Custodian may terminate its obligations under this Agreement upon at
least 45 days' prior written notice to the Purchaser. In the event of such
termination, the Purchaser shall appoint a successor Custodian. The payment of
such successor Custodian's fees and expenses shall be solely the
responsibility of the Company or any successor to the Company as servicer
pursuant to the Loan Sale Agreement. If notice of termination is given by the
Custodian, the Purchaser shall, within 30 days following the giving of such
notice, deliver to the Custodian proper instructions in writing specifying the
names of the persons to whom the Custodian shall deliver the Additional
Pledged Collateral held by it. The Custodian will deliver promptly the
Additional Pledged Collateral to the persons so specified, after deducting
therefrom any amounts which the Custodian is owed for services or
reimbursement of expenses hereunder.

     If within 30 days following the giving of a notice of termination by the
Custodian, the Custodian does not receive from the Purchaser proper
instructions in writing specifying the names of the persons to whom the
Custodian shall deliver the assets of the Purchaser held by it, the Custodian,
at its election, may seek court action with respect to the appointment of a
successor custodian.

     Section 13. Survival.

     The obligations of the parties hereto regarding the use of reasonable
care, indemnities and payment of fees and expenses shall survive the
termination of this Agreement.

     Section 14. Term of Agreement.

     Unless terminated pursuant to Section 11 or Section 12 hereof, this
Agreement shall terminate upon the earlier of (1) the resignation or removal
of the Custodian, its agent or affiliate as the servicer under the Loan Sale
Agreement, and (2) the final payment or other liquidation (or advance with
respect thereto) of the last Mortgage Loan or the disposition of all property
acquired upon foreclosure or deed in lieu of foreclosure of any Mortgage Loan,
and the final remittance of all funds due the Purchaser under the Loan Sale
Agreement. In such event, all Additional Pledged Collateral shall be released
in accordance with the written instructions of the Purchaser.

     This AMENDED AND RESTATED MORTGAGE LOAN SALE, WARRANTIES AND SERVICING
AGREEMENT (the "Agreement") is executed by and between Lehman Capital, A
Division of Lehman Brothers Holdings Inc., as purchaser (the "Purchaser"), and
Boston Safe Deposit and Trust Company, as seller and servicer (the "Company"),

                                  WITNESSETH

     WHEREAS, the Purchaser purchased from the Company and the Company sold to

an aggregate outstanding principal balance as of the close of business on the
Cut-off Date, after deduction of payments due on or before such date, of
$104,349,740.96 pursuant to the Original Agreement;

     WHEREAS, each of the Mortgage Loans is secured by a mortgage, deed of
trust or other security instrument creating a first lien on real estate (or

lease) located in the jurisdiction indicated on the Mortgage Loan Schedule,
which is annexed hereto as Exhibit A;

     WHEREAS, the Purchaser and the Company have agreed that the Purchaser

contemplated by this Agreement are in the ordinary course of business of the
Company, and the transfer, assignment and conveyance of the Mortgage Notes and
the Mortgages by the Company pursuant to this Agreement are not subject to the
bulk transfer or any similar statutory provisions in effect in any applicable
jurisdiction;

     (c)  No Conflicts. Neither the execution and delivery of this Agreement,
the origination or acquisition of the Mortgage Loans by the Company, the sale
of the Mortgage Loans to the Purchaser or the other transactions contemplated
hereby, nor the fulfillment of or compliance with the terms and conditions of
this Agreement, will conflict materially with or result in a material breach
of any of the terms, conditions or provisions of the Company's charter or
by-laws or any legal restriction or any agreement or instrument to which the
Company is now a party or by which it is bound, constitute a default or result
in an acceleration under any of the foregoing, or result in any material
violation of any law, rule, regulation, order, judgment or decree to which the
Company or its property is subject, or impair the ability of the Purchaser to
realize on the Mortgage Loans, or impair the value of the Mortgage Loans;

     (d)  Ability to Service. The Company is an approved seller/servicer of
conventional residential mortgage loans for FNMA or FHLMC, with the
facilities, procedures, and experienced personnel necessary for the servicing,
in accordance with Accepted Servicing Practices, of mortgage loans of the same
type as the Mortgage Loans, and is in good standing, to sell mortgage loans to
and service mortgage loans for FNMA or FHLMC, and no event has occurred,
including but not limited to a change in insurance coverage, which would make
the Company unable to comply with FNMA or FHLMC eligibility requirements or
which would require notification to either FNMA or FHLMC;

     (e)  Reasonable Servicing Fee. The Company acknowledges and agrees that
the Servicing Fee, as calculated at the Servicing Fee Rate, represents
reasonable compensation for performing such services and that the entire
Servicing Fee shall be treated by the Company, for accounting and tax
purposes, as compensation for the servicing and administration of the Mortgage
Loans pursuant to this Agreement;

     (f)  Ability to Perform. The Company does not believe, nor does it have
any reason or cause to believe, that it cannot perform each and every covenant
contained in this Agreement;

     (g)  No Litigation Pending. There is no action, suit, proceeding or
investigation pending or threatened against the Company which, either in any
one instance or in the aggregate, may result in any material adverse change in
the business, operations, financial condition, properties or assets of the
Company, or in any material impairment of the right or ability of the Company
to carry on its business substantially as now conducted, or in any material
liability on the part of the Company, or which would draw into question the
validity of this Agreement or the Mortgage Loans or of any action taken or to
be taken in connection with the obligations of the Company contemplated
herein, or which would be likely to impair materially the ability of the
Company to perform under the terms of this Agreement;

     (h)  No Consent Required. No consent, approval, authorization or order
of any court or governmental agency or body is required for the execution,
delivery and performance by the Company of or the compliance by the Company
with this Agreement or the sale of the Mortgage Loans as evidenced by the
consummation of the transactions contemplated by this Agreement, or if
required, such approval has been obtained prior to the Closing Date;

     (i)  Selection Process. The Mortgage Loans were selected from among the
outstanding adjustable rate one- to four- family mortgage loans in the
Company's portfolio at the Closing Date as to which the representations and
warranties set forth in Section 3.02 could be made and such selection was not
made in a manner so as to affect adversely the interests of the Purchaser;

     (j)  No Untrue Information. Neither this Agreement nor any statement,
report or other document furnished or to be furnished pursuant to this
Agreement or in connection with the transactions contemplated hereby contains
any materially untrue statement of fact or omits to state a fact necessary to
make the statements contained therein not misleading;

     (k) [RESERVED];

     (l) Sale Treatment. The Company has determined that the disposition of
the Mortgage Loans pursuant to this Agreement will be afforded sale treatment
for accounting and tax purposes;

     (m) Financial Statements. The Company has delivered to the Purchaser
consolidated financial statements of Mellon Bank Corporation, as to its last
two complete fiscal years and any later quarter ended more than sixty (60)
days prior to the execution of this Agreement. All such financial statements
fairly present the pertinent results of operations and affiliates and have
been prepared in accordance with generally accepted accounting principles
constantly applied throughout the periods involved, except as set forth in the
notes thereto. In addition, the Company has delivered information as to its
conventional mortgage loan delinquency and foreclosure experience for the
immediately preceding three-year period, in each case with respect to mortgage
loans owned by it and such mortgage loans serviced for others during such
period, and all such information so delivered is true and correct in all
material respects. There has been no change in the business, operations,
financial condition, properties or assets of the Company since the date of the
Company's financial statements that would have a material adverse effect on
its ability to perform its obligations under this Agreement. The Company has
completed any forms requested by the Purchaser in a timely manner and in
accordance with the provided instructions;

     (n) No Brokers' Fees. The Company has not dealt with any broker,
investment banker, agent or other person that may be entitled to any
commission or compensation in connection with the sale of the Mortgage Loans;
and

     (o) Fair Consideration. The consideration received by the Company upon
the sale of the Mortgage Loans under this Agreement constitutes fair
consideration and reasonably equivalent value for the Mortgage Loans.

     Section 3.02  Representations and Warranties Regarding Individual Mortgage
                   Loans

     As to each Mortgage Loan, the Company hereby represents and warrants to
the Purchaser that, as of the Closing Date:

     (a)  Mortgage Loans as Described. The information set forth in the
Mortgage Loan Schedule is complete, true and correct, in all material
respects;

     (b)  Payments Current. Except as set forth in Schedule 3.02(b), all
payments required to be made up to the Closing Date for the Mortgage Loan
under the terms of the Mortgage Note have been made and credited. No payment
required under the Mortgage Loan has been delinquent by more than thirty (30)
days more than one time within the twelve months preceding the Cut-off Date;

     (c)  No Outstanding Charges. There are no defaults in complying with the
terms of the Mortgages, and Company 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. The Company has not advanced funds,
directly or indirectly, for the payment of any amount required under the
Mortgage Loan, except for interest accruing from the date of the Mortgage Note
or date of disbursement of the Mortgage Loan proceeds, whichever is greater,
to the day which precedes by one month the Due Date of the first installment
of principal and interest;

     (d)  Original Terms Unmodified. The terms of the Mortgage Note and
Mortgage have not been impaired, waived, altered or modified in any respect,
except by a written instrument (which, if necessary to protect the interests
of the Purchaser, has been recorded) which has been delivered to the
Custodian;

     (e)  No Defenses. The Mortgage Loan is not subject to any right of
rescission, set-off, counterclaim or defense, including without limitation the
defense of usury, nor will the operation of any of the terms of the Mortgage
Note or the Mortgage, or the exercise of any right thereunder, render either
the Mortgage Note or the Mortgage unenforceable, in whole or in part, or
subject to any right of rescission, set-off, counterclaim or defense,
including without limitation the defense of usury, and no such right of
rescission, set-off, counterclaim or defense has been asserted with respect
thereto, and Company has no knowledge that any Mortgagor was a debtor in any
state or federal bankruptcy or insolvency proceeding at the time the Mortgage
Loan was originated;

     (f) Hazard Insurance. Except in the case of Coop Loans, the Mortgage
requires all buildings or other improvements on the 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 Mortgaged Property is located pursuant to insurance policies conforming to
the requirements of Section 4.10. 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
Section 4.10. All individual insurance policies contain a standard mortgagee
clause naming the Company and its successors and assigns as mortgagee, and all
premiums thereon have been paid. The Mortgage obligates the 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, the 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 Purchaser
upon the consummation of the transactions contemplated by this Agreement. The
Company has not engaged in, and has no knowledge of the Mortgagor's or any
Subservicer's having engaged in, any act or omission which would impair the
coverage of any such policy, the benefits of the endorsement provided for
therein, or the validity and binding effect of either, including without
limitation, no unlawful fee, commission, kickback or other unlawful
compensation or value of any kind has been or will be received, retained or
realized by any attorney, firm or other person or entity, and no such unlawful
items have been received, retained or realized by the Company;

     (g) Compliance with Applicable Laws. Any and all requirements of any
federal, state or local law including, without limitation, usury,
truth-in-lending, real estate settlement procedures, consumer credit
protection, equal credit opportunity or disclosure laws applicable to the
Mortgage Loan have been complied with, and the Company shall maintain in its
possession, available for the Purchaser's inspection, and shall deliver to the
Purchaser upon demand, evidence of compliance with all such requirements;

     (h)  No Satisfaction of Mortgage. The lien against the Mortgaged Property
has not been satisfied, canceled, 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 rescission. The
Company has not waived the performance by the Mortgagor of any action, if the
Mortgagor's failure to perform such action would cause the Mortgage Loan to be
in default, nor has the Company waived any default resulting from any action
or inaction by the Mortgagor;

     (i)  Location and Type of Mortgaged Property. Except for Coop Loans, the
Mortgaged Property is located in the state identified in the Mortgage Loan
Schedule and consists of a parcel of real property with a detached single
family residence erected thereon or upon which a detached single family
residence will be erected, or a two- to four- family dwelling, or an
individual condominium unit in a condominium project, or an individual unit in
a planned unit development. For Coop Loans, the Mortgaged Property consists of
shares of stock in a cooperative housing corporation and a leasehold interest
in a cooperative apartment owned by such corporation located in the state
identified in the Mortgaged Loan Schedule;

     (j)  Valid First Lien. The Mortgage is a valid, subsisting, enforceable
and perfected first lien on the Mortgaged Property. Where the Mortgaged
Property consists of residential real estate, the lien includes all buildings
on the Mortgaged Property and all installations and mechanical, electrical,
plumbing, heating and air conditioning systems located in or annexed to such
building, and all additions, alterations, and replacements made at any time
with respect to the foregoing. The lien of the Mortgage is subject only to:

               (1) the lien of current real property taxes and assessments not
          yet due and payable;

               (2) covenants, conditions and restrictions, rights of way,
          easements and other matters of the public record as of the date of
          recording acceptable to mortgage lending institutions generally and
          specifically referred to in the lender's title insurance policy
          delivered to the originator of the Mortgage Loan and (i) referred to
          or otherwise considered in the appraisal made for the originator of
          the Mortgage Loan or (ii) which do not adversely affect the
          Appraised Value of the Mortgaged Property set forth in such
          appraisal; and

               (3) other matters to which like properties are commonly subject
          which do not materially interfere with the benefits of the security
          intended to be provided by the Mortgage or the use, enjoyment, value
          or marketability of the related Mortgaged Property.

Any security agreement, chattel mortgage or equivalent document related to and
delivered in connection with the Mortgage Loan establishes and creates a
valid, subsisting and enforceable first lien and first priority security
interest on the Mortgaged Property and any additional collateral for the
Mortgage Loan and the Company has full right to sell and assign the same to
the Purchaser;

     (k) Validity of Mortgage Documents. The Mortgage Note and the Mortgage
are genuine, and each is the legal, valid and binding obligation of the maker
thereof enforceable in accordance with its terms. All parties to the Mortgage
Note and the Mortgage and any other related agreement had legal capacity to
enter into the Mortgage Loan and to execute and deliver the Mortgage Note and
the Mortgage and any other related agreement, and the Mortgage Note and the
Mortgage have been duly and properly executed by such parties. The documents,
instruments and agreements submitted for loan underwriting were not falsified
and contain no untrue statement of material fact or omit to state a material
fact required to be stated therein or necessary to make the information and
statements therein not misleading. No fraud was committed in connection with
the origination of the Mortgage Loan. The Company has reviewed all of the
documents constituting the Servicing File and has made such inquiries as it
deems necessary to make and confirm the accuracy of the representations set
forth herein;

     (l) Full Payment of Costs. All costs, fees and expenses incurred in
making or closing the Mortgage Loan and the recording of the Mortgage were
paid, and the Mortgagor is not entitled to any refund of any amounts paid or
due under the Mortgage Note or Mortgage;

     (m) Ownership. Immediately prior to the sale of the Mortgage Loans by the
Company to the Purchaser pursuant to this Agreement, the Company was the sole
owner of record and holder of the Mortgage Loan. The Mortgage Loan is not
assigned or pledged, and the Company has good and marketable title thereto,
and has full right to transfer and sell the Mortgage Loan therein to the
Purchaser free and clear 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;

     (n) Doing Business. All parties which have had any interest in the
Mortgage Loan, whether as mortgagee, assignee, pledgee or otherwise, are (or,
during the period in which they held and disposed of such interest, were) (1)
in compliance with any and all applicable licensing requirements of the laws
of the state wherein the real Mortgaged Property is located, and (2) organized
under the laws of such state, or (3) qualified to do business in such state,
or (4) federal savings and loan associations or national banks having
principal offices in such state, or (5) not doing business in such state;

     (o) LTV. No Mortgage Loan has a Loan-to-Value Ratio at origination (or,
if any Mortgage Loan has been the subject of a significant modification since
origination, other than as a result of a default or imminent default, as of
the date of such modification) equal to or greater than 90%.

     (p) Title Insurance. Except in the case of Coop Loans, the Mortgage Loan
is covered by either (i) an attorney's opinion of title and abstract of title
the form and substance of which is acceptable to mortgage lending institutions
making mortgage loans in the area where the Mortgaged Property is located or
(ii) an ALTA lender's title insurance policy or other generally acceptable
form of policy of insurance acceptable to FNMA or FHLMC, issued by a title
insurer acceptable to FNMA or FHLMC and qualified to do business in the
jurisdiction where the Mortgaged Property is located, insuring the Company,
its successors and assigns, as to the first priority lien of the Mortgage in
the original principal amount of the Mortgage Loan, and against any loss by
reason of the invalidity or enforceability of the lien resulting from the
provisions of the Mortgage providing for adjustment in the Mortgage Interest
Rate and Monthly Payment, subject only to the exceptions contained in clauses
(1), (2) and (3) of paragraph (j) of this Section 3.02 and against any loss
resulting from the provisions of the Mortgage providing for adjustment to the
Mortgage Interest Rate and Monthly Payment. Where required by state law or
regulation, the Mortgagor has been given the opportunity to choose the carrier
of the required mortgage title insurance. Additionally, such lender's title
insurance policy affirmatively insures ingress and egress, and against
encroachments by or upon the Mortgaged Property or any interest therein. 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. The Company is the sole insured of such lender's title
insurance policy, and such lender's title insurance policy is in full force
and effect and will be in force and effect upon the consummation of the loan
sale transaction contemplated by this Agreement. No claims have been made
under such lender's title insurance policy, and no prior holder of the
Mortgage, including the Company, has done, by act or omission, anything which
would impair the coverage of such lender's title insurance policy including
without limitation, no unlawful fee, commission, kickback or other unlawful
compensation or value of any kind has been or will be received, retained or
realized by any attorney, firm or other person or entity, and no such unlawful
items have been received, retained or realized by the Company;

     (q) No Defaults. There is no default, breach, violation or event of
acceleration existing under the Mortgage or the Mortgage Note and no event
which, with the passage of time or with notice and the expiration of any grace
or cure period, would constitute a default, breach, violation or event of
acceleration, and neither the Company nor its predecessors have waived any
default, breach, violation or event of acceleration, and no foreclosure action
has been commenced with respect to any Mortgage Loan;

     (r) No Mechanics' Liens. 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
Mortgaged Property which are or may be liens prior to, or equal or subordinate
with the lien of the related Mortgage;

     (s) Location of Improvements; No Encroachments. All improvements which
were considered in determining the Appraised Value of the Mortgaged Property
lay wholly within the boundaries and building restriction lines of the
Mortgaged Property (and, if the property is a condominium unit, such
improvements lie wholly within the project) and no improvements on adjoining
properties encroach upon the Mortgaged Property. No improvement located on or
being part of the Mortgaged Property is in violation of any applicable zoning
law or regulation;

     (t) Origination; Payment Terms. At the time the Mortgage Loan was
originated, the originator was a Mortgagee approved by the Secretary of
Housing and Urban Development pursuant to Sections 203 and 211 of the National
Housing Act or a savings and loan association, a savings bank, a commercial
bank or similar banking institution which is supervised and examined by a
Federal or State authority. The documents, instruments and agreements
submitted for loan underwriting were not falsified and contain no untrue
statement of material fact or omit to state a material fact required to be
stated therein or necessary to make the information and statements therein not
misleading. The Mortgage Interest Rate is adjusted on each Interest Rate
Adjustment Date to equal the Index plus the Gross Margin, which amount is
added in accordance with the terms of the Mortgage Note, subject to the
Mortgage Interest Rate Cap. The Mortgage Note is payable each month in
installments of principal and/or interest, which installments of interest are
subject to change due to the adjustments to the Mortgage Interest Rate on each
Interest Rate Adjustment Date, with interest calculated and payable in
arrears, sufficient to amortize the Mortgage Loan fully by the stated maturity
date, over an original term of not more than thirty (30) years. The Mortgage
Note provides for accrual of interest on the basis of a 360 day year
consisting of twelve 30-day months. There is no negative amortization. At no
time has the Mortgage Interest Rate exceeded the lifetime cap as set forth in
the related Note.

     (u) Customary Provisions. The Mortgage contains customary and enforceable
provisions such as to render the rights and remedies of the holder thereof
adequate for the realization against the Mortgaged Property of the benefits of
the security provided thereby, including (i) in the case of a Mortgage
designated as a deed of trust, by trustee's sale, and (ii) otherwise by
judicial foreclosure. Upon default by a Mortgagor on a Mortgage Loan,
foreclosure on, or trustee's sale of, the Mortgaged Property pursuant to the
proper procedures, the holder of the Mortgage Loan will be able to deliver
good and merchantable title to the Mortgaged Property. There is no homestead
or other exemption available to a Mortgagor which would interfere with the
right to sell the Mortgaged Property at a trustee's sale or the right to
foreclose the Mortgage;

     (v) Underwriting. The Mortgage Loans were generally underwritten and
approved substantially in accordance with the Company's written procedures and
standards set forth in Exhibit A-1.

     (w) Occupancy of the Mortgaged Property. As of the Closing Date the
Mortgaged Property (or, in the case of a Coop Loan, the related Cooperative
Unit) is lawfully occupied under applicable law. All inspections, licenses and
certificates required to be made or issued with respect to all occupied
portions of the Mortgaged Property (or, in the case of a Coop Loan, the
related Cooperative Unit) and, with respect to the use and occupancy of the
same, including but not limited to certificates of occupancy and fire
underwriting certificates, have been made or obtained from the appropriate
authorities;

     (x) No Additional Collateral. With the exception of Mortgage Loans
identified on the Mortgage Loan Schedule as having additional collateral, the
Mortgage Note is not secured by any collateral except the lien on Mortgaged
Property created by the corresponding Mortgage and the security interest or
any applicable security agreement or chattel mortgage referred to in Section
3.02(j) above;

     (y) Deeds of Trust. In the event the Mortgage constitutes a deed of
trust, a trustee, duly qualified under applicable law to serve as such, has
been properly designated and currently so serves and is named in the Mortgage,
and no fees or expenses are or will become payable by the Purchaser to the
trustee under the deed of trust, except in connection with a trustee's sale
after default by the Mortgagor;

     (z) Acceptable Investment. The Company has no knowledge of any
circumstances or conditions with respect to the Mortgage, the Mortgaged
Property, the Mortgagor and/or the Mortgagor's credit standing that can
reasonably be expected to:

               (i) cause private institutional investors to regard the
Mortgage Loan as an unacceptable investment;

               (ii) cause the Mortgage Loan to become delinquent; or

               (iii) adversely affect the value or marketability of the
Mortgage Loan;

     (aa) Delivery of Mortgage Documents. The Mortgage Loan Documents have
been delivered (or will have been released by the Closing Date) to the
Custodian. The Company is in possession of a complete, true and accurate
Mortgage File in compliance with Exhibit B, except for such documents the
originals of which have been delivered to the Custodian;

     (bb) Appraisal. The Mortgage File contains an appraisal of the related
Mortgaged Property conducted by a qualified appraiser, duly appointed by the
Company, who had no interest direct or indirect in the Mortgaged Property or
in any loan made on the security thereof, and whose compensation is not
affected by the approval or disapproval of the Mortgage Loan, and the
appraisal and appraiser both satisfy the requirements of Title XI of the
Federal Institution Reform, Recovery, and Enforcement Act of 1989 and the
regulations promulgated thereunder, all as in effect on the date the Mortgage
Loan was originated;

     (cc) Transfer of Mortgage Loans. The Assignment of Mortgage is in
recordable form and is acceptable for recording under the laws of the
jurisdiction in which the Mortgaged Property consisting of residential real
estate is located;

     (dd) Due on Sale. The Mortgage contains an enforceable provision for the
acceleration of the payment of the unpaid principal balance of the Mortgage
Loan in the event that the Mortgaged Property is sold or transferred without
the prior written consent of the mortgagee thereunder;

     (ee) Conversion to Fixed Interest Rate. Except as set forth in Schedule
3.02 (ee), the Mortgage Loan does not contain a provision permitting or
requiring conversion to a fixed interest rate Mortgage Loan;

     (ff) Consolidation of Future Advances. None of the Mortgage Loans contain
any provisions permitting future advances after the Cut-off Date. Any future
advances made prior to the Cut-off Date have been consolidated with the
outstanding principal amount secured by the Mortgage, and the secured
principal amount, as consolidated, bears a single interest rate and single
repayment term. Except in the case of Coop Loans, the lien of the Mortgage
securing the consolidated principal amounts is insured as having first lien
priority by a title insurance policy, and endorsement to the policy insuring
the mortgagee's consolidated interest or by other title evidence. The
consolidated principal amount does not exceed the original principal amount of
the Mortgage Loan;

     (gg) Mortgaged Property Undamaged. There is no proceeding pending or, to
the best of the Company's knowledge, threatened for the total or partial
condemnation of the Mortgaged Property. The Mortgaged Property is undamaged by
waste, fire, earthquake or earth movement, windstorm, flood, tornado or other
casualty so as to affect adversely the value of the Mortgaged Property as
security for the Mortgage Loan or the use for which the premises were
intended;

     (hh) Collection Practices; Escrow Deposits; Interest Rate Adjustments.
The origination and collection practices used with respect to the Mortgage
Loan have been in accordance with Accepted Servicing Practices, and have been
in all respects in compliance with all applicable laws and regulations. All
Mortgage Interest Rate adjustments have been made in compliance with state and
federal law and the terms of the related Mortgage Note. Any interest required
to be paid pursuant to state and local law has been properly paid and
credited;

     (ii) Environmental Matters. To the best of the Company's knowledge, the
Mortgaged Property is free from any and all toxic or hazardous substances and
there exists no violation of any local, state or federal environmental law,
rule or regulation;

     (jj) Soldiers' and Sailors' Relief Act. The Mortgagor has not notified
the Company, and the Company has no knowledge, of any relief requested or
allowed to the Mortgagor under the Soldiers' and Sailors' Civil Relief Act of
1940;

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

     (ll) Buydown Mortgage Loans. None of the Mortgage Loans is a Buydown
Mortgage Loan; and

     (mm) No Partial Release of Collateral. No Mortgage Loan requires the
Mortgagee to release any portion of the Mortgaged Property from the lien of
the Mortgage other than (i) upon payment in full of the Mortgage Loan or (ii)
with respect to Mortgaged Property consisting of more than one piece of real
property or shares of a cooperative corporation, a release of a portion of the
Mortgaged Property upon a partial repayment of the Mortgage Loan, provided the
LTV of the remaining Mortgaged Property after the release does not exceed 90%.

     Section 3.03 Remedies for Breach of Representations and Warranties.

     It is understood and agreed that the representations and warranties set
forth in Sections 3.01 and 3.02 shall survive the sale of the Mortgage Loans
to the Purchaser and the subsequent sale of the Mortgage Loans by the
Purchaser to the Depositor and by the Depositor to the Trustee under the Trust
Agreement, and the delivery of the Mortgage Loan Documents to the Custodian
and shall inure to the benefit of the Purchaser, specifically, including the
Trustee, as provided in Section 11.10 hereof, notwithstanding any restrictive
or qualified endorsement on any Mortgage Note or Assignment of Mortgage or the
examination or failure to examine any Mortgage File. Upon discovery by either
the Company or the Purchaser of a breach of any of the foregoing
representations and warranties which materially and adversely affects the
value of the Mortgage Loans or the interest of the Purchaser (or which
materially and adversely affects the interests of the Purchaser in the related
Mortgage Loan in the case of a representation and warranty relating to a
particular Mortgage Loan) the party discovering such breach shall give prompt
written notice to the other.

     Within sixty (60) days of the earlier of either discovery by or notice to
the Company of any breach of a representation or warranty which materially and
adversely affects the value of the Mortgage Loans or the interest of the
Purchaser (or which materially and adversely affects the interests of
Purchaser in the related Mortgage Loan in the case of a representation and
warranty relating to a particular Mortgage Loan), the Company shall use its
best efforts promptly to cure such breach in all material respects and, if
such breach cannot be cured, the Company shall, at the Purchaser's option,
repurchase such Mortgage Loan at the Repurchase Price. In the event that a
breach shall involve any representation or warranty set forth in Section 3.01,
and either discovery by or notice to the Company of such breach, all of the
Mortgage Loans shall, at the Purchaser's option, be repurchased by the Company
at the Repurchase Price. However, if the breach shall involve a representation
or warranty set forth in Section 3.02 and the Company discovers or receives
notice of any such breach within 120 days of the Closing Date, the Company
shall, at the Purchaser's option and provided that the Company has a Qualified
Substitute Mortgage Loan, rather than repurchase the Mortgage Loan as provided
above, remove such Mortgage Loan (a "Deleted Mortgage Loan") and substitute in
its place a Qualified Substitute Mortgage Loan or Loans, provided that no such
substitution shall be made (i) after the 120-day period beginning on the
Closing Date and (ii) unless the Purchaser has received an Opinion of Counsel
(at the expense of the Company) that such substitution will not adversely
affect the status of any REMIC established pursuant to the Trust Agreement as
a REMIC or cause any such REMIC to be deemed to have engaged in a "prohibited
transaction" under the REMIC provisions. If the Company has no Qualified
Substitute Mortgage Loan, it shall repurchase the deficient Mortgage Loan. Any
repurchase of a Mortgage Loan or Loans pursuant to the foregoing provisions of
this Section 3.03 shall be accomplished by deposit in the Custodial Account of
the amount of the Repurchase Price for distribution to Purchaser on the next
scheduled Remittance Date, after deducting therefrom any amount received in
respect of such repurchased Mortgage Loan or Loans and being held in the
Custodial Account for future distribution.

     At the time of repurchase or substitution, the Purchaser and the Company
shall arrange for the reassignment of the Deleted Mortgage Loan to the Company
and the delivery to the Company of any documents held by the Custodian
relating to the Deleted Mortgage Loan. In the event of a repurchase or
substitution, the Company shall, simultaneously with such reassignment, give
written notice to the Purchaser that such repurchase or substitution has taken
place, amend the Mortgage Loan Schedule to reflect the withdrawal of the
Deleted Mortgage Loan from this Agreement, and, in the case of substitution,
identify a Qualified Substitute Mortgage Loan and amend the Mortgage Loan
Schedule to reflect the addition of such Qualified Substitute Mortgage Loan to
this Agreement. In connection with any such substitution, the Company shall be
deemed to have made as to such Qualified Substitute Mortgage Loan the
representations and warranties set forth in this Agreement except that all
such representations and warranties set forth in this Agreement shall be
deemed made as of the date of such substitution. The Company shall effect such
substitution by delivering to the Custodian for such Qualified Substitute
Mortgage Loan the related Mortgage Loan Documents with the Mortgage Note
endorsed as required. No substitution will be made in any calendar month after
the Determination Date for such month. The Company shall deposit in the
Custodial Account the Monthly Payment less the Servicing Fee due on such
Qualified Substitute Mortgage Loan or Loans in the month following the date of
such substitution. Monthly Payments due with respect to Qualified Substitute
Mortgage Loans in the month of substitution shall be retained by the Company.
For the month of substitution, distributions to Purchaser shall include the
Monthly Payment due on any Deleted Mortgage Loan in the month of substitution.
The Company shall thereafter be entitled to retain all amounts subsequently
received by the Company in respect of such Deleted Mortgage Loan.

     For any month in which the Company substitutes a Qualified Substitute
Mortgage Loan for a Deleted Mortgage Loan the Company shall determine the
amount (if any) by which the aggregate principal balance of all Qualified
Substitute Mortgage Loans as of the date of substitution is less than the
aggregate Stated Principal Balance of all Deleted Mortgage Loans (after
application of scheduled principal payments due in the month of substitution).
The amount of such shortfall shall be distributed by the Company in the month
of substitution pursuant to Section 5.01. Accordingly, on the date of such
substitution, the Company shall deposit from its own funds into the Custodial
Account an amount equal to the amount of such shortfall.

     In addition to such repurchase or substitution obligation, the Company
shall indemnify the Purchaser and hold it harmless against any losses,
damages, penalties, fines, forfeitures, reasonable and necessary 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 Company's representations and warranties contained in
this Agreement. It is understood and agreed that the obligations of the
Company set forth in this Section 3.03 to cure, substitute for or repurchase a
defective Mortgage Loan and to indemnify the Purchaser as provided in this
Section 3.03 constitute the sole remedies of the Purchaser respecting a breach
of the foregoing representations and warranties.

     Any cause of action against the Company relating to or arising out of the
breach of any representations and warranties made in Section 3.01 and 3.02
shall accrue as to any Mortgage Loan upon (i) discovery of such breach by the
Purchaser or notice thereof by the Company to the Purchaser, (ii) failure by
the Company to cure such breach or repurchase such Mortgage Loan as specified
above, and (iii) demand upon the Company by the Purchaser for compliance with
this Agreement.

     Section 3.04 Mortgage Loans Convertible to Fixed Interest Rate.

     In the event the Mortgagor under any Convertible Mortgage Loan elects
to convert said Mortgage Loan to a fixed interest rate Mortgage Loan, as
provided in the related Mortgage Note, then the Company shall repurchase such
Mortgage Loan at the Repurchase Price or substitute in its place a Qualified
Substitute Mortgage Loan or Loans in the manner prescribed in Section 3.03.

                                  ARTICLE IV

                ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

     Section 4.01 Company to Act as Servicer.

     The Company, as an independent contractor, shall service and administer
the Mortgage Loans and shall have full power and authority, acting alone, to
do any and all things in connection with such servicing and administration
which the Company may deem necessary or desirable, consistent with the terms
of this Agreement and with Accepted Servicing Practices.

     Consistent with the terms of this Agreement, the Company 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 Company shall not
make any future advances with respect to a Mortgage Loan and (unless the
Mortgagor is in default with respect to the Mortgage Loan or such default is,
in the judgment of the Company, imminent) the Company shall not permit any
modification 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, unless approved by Purchaser on a
Mortgage Loan-by-Mortgage Loan basis (which approval shall not be unreasonably
withheld, conditioned or delayed), or unless pursuant to a loan modification
program previously presented to and approved by the Purchaser. In the event of
any such modification which permits the deferral of interest or principal
payments on any Mortgage Loan, the Company shall, on the Business Day
immediately preceding the Remittance Date in any month in which any such
principal or interest payment has been deferred, deposit in the Custodial
Account from its own funds, in accordance with Section 5.03, the difference
between (a) such month's principal and one month's interest at the Mortgage
Loan Remittance Rate on the unpaid principal balance of such Mortgage Loan and
(b) the amount paid by the Mortgagor. The Company shall be entitled to
reimbursement for such advances to the same extent as for all other advances
made pursuant to Section 5.03. Without limiting the generality of the
foregoing, the Company shall continue, and is hereby authorized and empowered,
to execute, deliver and record (if appropriate) on behalf of itself and the
Purchaser, all instruments of satisfaction or cancellation, or of partial or
full release, discharge and all other comparable instruments and any other
certificate or instrument necessary to carry out the modifications
contemplated by this Section 4.01, with respect to the Mortgage Loans and with
respect to the Mortgaged Properties. The Purchaser has furnished and upon
request shall furnish the Company with any powers of attorney and other
documents reasonably required by the Company which are necessary or
appropriate to enable the Company to carry out its servicing and
administrative duties under this Agreement.

     In the event that foreclosure proceedings are commenced in respect of any
Mortgage Loan as to which Additional Collateral has been pledged as security,
the Company shall, if such Additional Collateral is readily marketable,
immediately commence the liquidation of such collateral. The proceeds of such
sale shall be promptly deposited in the Custodial Account. If such Additional
Collateral is not readily marketable, the Company shall not exercise any right
it may have to seize, convert or otherwise assume ownership of such Additional
Collateral.

     In servicing and administering the Mortgage Loans, the Company shall
employ procedures (including collection procedures) and exercise the same care
that it customarily employs and exercises in servicing and administering
mortgage loans for its own account, giving due consideration to Accepted
Servicing Practices where such practices do not conflict with the requirements
of this Agreement, and the Purchaser's reliance on the Company.

     The Mortgage Loans may be subserviced by the Subservicer, in
accordance with the servicing provisions of this Agreement, on behalf of the
Company, provided that the Subservicer is a FNMA-approved lender or a FHLMC
seller/servicer in good standing, and no event has occurred, including but not
limited to a change in insurance coverage, which would make it unable to
comply with the eligibility requirements for lenders imposed by FNMA or for
seller/servicers imposed by FHLMC, or which would require notification to FNMA
or FHLMC. The Company may perform any of its servicing responsibilities
hereunder or may cause the Subservicer to perform any such servicing
responsibilities on its behalf, but the use by the Company of the Subservicer
shall not release the Company from any of its obligations hereunder and the
Company shall remain responsible hereunder for all acts and omissions of the
Subservicer as fully as if such acts and omissions were those of the Company.
The Company shall pay all fees and expenses of the Subservicer from its own
funds, and the Subservicer's fee shall not exceed the Servicing Fee.

     References in this Agreement to performance by the Company of its
servicing responsibilities hereunder shall be deemed to include the
Subservicer acting on behalf of the Company.

     At the cost and expense of the Company, without any right of
reimbursement from the Custodial Account, the Company shall be entitled to
terminate the rights and responsibilities of the Subservicer and arrange for
any servicing responsibilities to be performed by a successor Subservicer
meeting the requirements in the two preceding paragraphs; provided, however,
that nothing contained herein shall be deemed to prevent or prohibit the
Company, at the Company's option, from electing to service the related
Mortgage Loans itself. In the event that the Company's responsibilities and
duties under this Agreement are terminated pursuant to Section 8.04, 9.01,
10.01 or 10.02 , and if requested to do so by the Purchaser, the Company shall
at its own cost and expense terminate the rights and responsibilities of the
Subservicer as soon as is reasonably possible. The Company shall pay all fees,
expenses or penalties necessary in order to terminate the rights and
responsibilities of the Subservicer from the Company's own funds without
reimbursement from the Purchaser.

     Notwithstanding any of the provisions of this Agreement relating to
agreements or arrangements between the Company and the Subservicer or any
reference herein to action taken though the Subservicer or otherwise, the
Company shall not be relieved of its obligations to the Purchaser and shall be
obligated to the same extent and under the same terms and conditions as if it
alone were servicing and administering the Mortgage Loans. The Company shall
be entitled to enter into an agreement with the Subservicer for
indemnification of the Company by the Subservicer and nothing contained in
this Agreement shall be deemed to limit or modify such indemnification.

     Any Subservicing Agreement and any other transactions or services
relating to the Mortgage Loans involving the Subservicer shall be deemed to be
between the Subservicer and Company alone, and the Purchaser shall have no
obligations, duties or liabilities with respect to the Subservicer including
no obligation, duty or liability of Purchaser to pay the Subservicer's fees
and expenses. For purposes of distributions and advances by the Company
pursuant to this Agreement, the Company shall be deemed to have received a
payment or other recovery in respect of a Mortgage Loan when the Subservicer
has received such payment or recovery.

     Section 4.02 Liquidation of Mortgage Loans.

     In the event that any payment due under any Mortgage Loan and not
postponed pursuant to Section 4.01 is not paid when the same becomes due and
payable, or in the event the Mortgagor fails to perform any other covenant or
obligation under the Mortgage Loan and such failure continues beyond any
applicable grace period, the Company shall take such action as (1) the Company
would take under similar circumstances with respect to a similar mortgage loan
held for its own account for investment, (2) shall be consistent with Accepted
Servicing Practices, and (3) the Company shall determine prudently to be in
the best interest of Purchaser. In the event that any payment due under any
Mortgage Loan is not postponed pursuant to Section 4.01 and remains delinquent
for a period of ninety (90) days or any other default continues for a period
of ninety (90) days beyond the expiration of any grace or cure period, the
Company shall commence foreclosure proceedings, provided that, prior to
commencing foreclosure proceedings, the Company shall notify the Purchaser in
writing of the Company's intention to do so, and the Company shall not
commence foreclosure proceedings if the Purchaser objects to such action
within ten (10) Business Days of receiving such notice. The Company's
obligation to make such Monthly Advances shall terminate upon delivery by the
Company to the Purchaser of a Certificate of Nonrecoverable Advance in the
form set forth in Exhibit M.

     Notwithstanding anything to the contrary contained herein, in connection
with a foreclosure or acceptance of a deed in lieu of foreclosure, in the
event the Company has reasonable cause to believe that a Mortgaged Property is
contaminated by hazardous or toxic substances or wastes, or if the Purchaser
otherwise requests an environmental inspection, a review of such Mortgaged
Property shall be conducted by a qualified inspector. Upon completion of the
inspection, the Company shall promptly provide the Purchaser with a written
report of the environmental inspection.

     In the event that the environmental inspection report indicates that the
Mortgaged Property is contaminated by hazardous or toxic substances or wastes,
the Company shall not proceed with foreclosure or acceptance of a deed in lieu
of foreclosure, and the Company shall be reimbursed for all Servicing Advances
made with respect to the related Mortgaged Property from the Custodial Account
pursuant to Section 4.05 hereof.

     Section 4.03 Collection of Mortgage Loan Payments.

     Continuously from the date hereof until the principal and interest on
all Mortgage Loans are paid in full, the Company shall proceed diligently to
collect all payments due under each of the Mortgage Loans when the same shall
become due and payable and shall take special care in ascertaining and
estimating Escrow Payments and all other charges that will become due and
payable with respect to the Mortgage Loan and the Mortgaged Property, to the
end that the installments payable by the Mortgagor will be sufficient to pay
such charges as and when they become due and payable.

     Section 4.04 Establishment of and Deposits to Custodial Account.

     The Company shall segregate and hold all funds collected and received
pursuant to a Mortgage Loan separate and apart from any of its own funds and
general assets and shall establish and maintain one or more Custodial
Accounts, in the form of time deposit or demand accounts, titled "Boston Safe
Deposit and Trust Company in trust for Norwest Bank Minnesota, National
Association, as Trustee, Structured Asset Securities Corporation Mortgage
Pass-Through Certificates, Series 1998-5," or such other designation as the
Purchaser may direct. The Custodial Account shall be established with a
Qualified Depository. Any funds deposited in the Custodial Account shall at
all times be fully insured to the full extent permitted under applicable law.
Funds deposited in the Custodial Account may be drawn on by the Company in
accordance with Section 4.05. The creation of any Custodial Account shall be
evidenced by a certification in the form of Exhibit D-1 hereto, in the case of
an account established with the Company, or by a letter agreement in the form
of Exhibit D-2 hereto, in the case of an account held by a depository other
than the Company. A copy of such certification or letter agreement shall be
furnished to the Purchaser and, upon request, to any subsequent Purchaser.

     Funds in a Custodial Account may be invested in Eligible Investments
(as defined in the Trust Agreement) which shall mature not later than the
earlier of the Business Day immediately preceding the next succeeding
Remittance Date, and such investments shall not be sold or disposed of prior
to their maturity. All income and gain realized from any investment shall be
for the benefit of the Company and shall be subject to its withdrawal or
order. The amount of any losses incurred in respect of any such investments
shall be deposited in the related Custodial Account by the Company out of its
own funds immediately as such loss is realized.

     The Company shall deposit in the Custodial Account on a daily basis, as
received, and retain therein, the following collections received by the
Company and payments made by the Company after the Cut-off Date, other than
payments of principal and interest due on or before the Cut-off Date:

     (i) all payments on account of principal on the Mortgage Loans, including
all Principal Prepayments;

     (ii) all payments on account of interest on the Mortgage Loans adjusted
to the Mortgage Loan Remittance Rate;

     (iii) all Liquidation Proceeds;

     (iv) all Insurance Proceeds including amounts required to be deposited
pursuant to Section 4.10 (other than proceeds to be held in the Escrow Account
and applied to the restoration or repair of the Mortgaged Property or released
to the Mortgagor in accordance with Section 4.14) and Section 4.11;

     (v) all Condemnation Proceeds which are not applied to the restoration or
repair of the Mortgaged Property or released to the Mortgagor in accordance
with Section 4.14;

     (vi) any amount required to be deposited in the Custodial Account
pursuant to Section 4.01, 4.04, 5.03, 6.01 or 6.02;

     (vii) any amounts payable in connection with the repurchase of any
Mortgage Loan pursuant to Section 3.03 and all amounts required to be
deposited by the Company in connection with a shortfall in principal amount of
any Qualified Substitute Mortgage Loan pursuant to Section 3.03;

     (viii) with respect to each Principal Prepayment received during the
immediately preceding Principal Prepayment Period, an amount (to be paid by
the Company out of its funds as provided in Section 6.03 hereof) which, when
added to all amounts allocable to interest received in connection with such
Principal Prepayment, equals one month's interest on the amount of principal
so prepaid at the Mortgage Loan Remittance Rate, the aggregate of such
payments by the Company for any month not to exceed the aggregate of the
Company's Servicing Fees for such month.

     (ix) any amounts required to be deposited by the Company pursuant to
Section 4.11 in connection with the deductible clause in any blanket hazard
insurance policy; and

     (x) any amounts received with respect to or related to any REO Property
and all REO Disposition Proceeds pursuant to Section 4.15.

     The foregoing requirements for deposit into the Custodial Account shall
be exclusive, it being understood and agreed that, without limiting the
generality of the foregoing, payments in the nature of late payment charges
and assumption fees, to the extent permitted by Section 6.01, need not be
deposited by the Company into the Custodial Account. Any interest paid on
funds deposited in the Custodial Account by the depository institution shall
accrue to the benefit of the Company and the Company shall be entitled to
retain and withdraw such interest from the Custodial Account pursuant to
Section 4.05.

     Section 4.05 Permitted Withdrawals From Custodial Account.

     The Company shall, from time to time, withdraw funds from the Custodial
Account for the following purposes:

     (i) to make payments to the Purchaser in the amounts and in the manner
provided for in Section 5.01;

     (ii) to reimburse itself for Monthly Advances of the Company's funds made
pursuant to Section 5.03, the Company's right to reimburse itself pursuant to
this subclause (ii) being limited to amounts received with respect to the
related Mortgage Loan which represent late payments of principal and/or
interest respecting which any such advance was made, it being understood that,
in the case of any such reimbursement, the Company's right thereto shall be
prior to the rights of the Purchaser, except that, where the Company is
required to repurchase a Mortgage Loan pursuant to Section 3.03 or 6.02, the
Company's right to such reimbursement shall be subsequent to the payment to
the Purchaser of the Repurchase Price pursuant to such sections and all other
amounts required to be paid to the Purchaser with respect to such Mortgage
Loan;

     (iii) to reimburse itself for unreimbursed Servicing Advances, and for
any unpaid Servicing Fees, the Company's right to reimburse itself pursuant to
this subclause (iii) with respect to any Mortgage Loan being limited to
related Liquidation Proceeds, Condemnation Proceeds, Insurance Proceeds and
such other amounts as may be collected by the Company from the Mortgagor or
otherwise relating to the Mortgage Loan, it being understood that, in the case
of any such reimbursement, the Company's right thereto shall be prior to the
rights of Purchaser except where the Company is required to repurchase a
Mortgage Loan pursuant to Section 3.03 or 6.02, in which case the Company's
right to such reimbursement shall be subsequent to the payment to the
Purchaser of the Repurchase Price pursuant to such sections and all other
amounts required to be paid to the Purchaser with respect to such Mortgage
Loan;

     (iv) to pay itself investment earnings on funds deposited in the
Custodial Account;

     (v) to reimburse itself for expenses incurred and reimbursable to it
pursuant to Sections 4.02 and 8.01;

     (vi) to pay any amount required to be paid pursuant to Sections 4.02 and
4.15 related to any REO Property, it being understood that in the case of any
such expenditure or withdrawal related to a particular REO Property, the
amount of such expenditure or withdrawal from the Custodial Account shall be
limited to amounts on deposit in the Custodial Account with respect to the
related REO Property;

     (vii) to withdraw funds deposited in error in the Custodial Account; and

     (viii) to clear and terminate the Custodial Account upon the termination
of this Agreement.

     On each Remittance Date, the Company shall withdraw all funds from the
Custodial Account except for those amounts which, pursuant to Section 5.01,
the Company is not obligated to remit on such Remittance Date. The Company may
use such withdrawn funds only for the purposes described in this Section 4.05.

     Section 4.06 Establishment of and Deposits to Escrow Account.

     The Company shall segregate and hold all funds collected and received
pursuant to a Mortgage Loan constituting Escrow Payments separate and apart
from any of its own funds and general assets and shall establish and maintain
one or more Escrow Accounts, in the form of time deposit or demand accounts
titled, "Boston Safe Deposit and Trust Company, in trust for Norwest Bank
Minnesota, National Association, as Trustee, Structured Asset Securities
Corporation Mortgage Pass-Through Certificates, Series 1998-5," or such other
designation as the Purchaser may direct. The Escrow Account shall be
established with a Qualified Depository, in a manner which shall provide
maximum available insurance thereunder. Funds deposited in the Escrow Account
may be drawn on by the Company in accordance with Section 4.07. The creation
of any Escrow Account shall be evidenced by a certification in the form of
Exhibit E-1 hereto, in the case of an account established with the Company, or
by a letter agreement in the form of Exhibit E-2 hereto, in the case of an
account held by a depository other than the Company. A copy of such
certification shall be furnished to the Purchaser and, upon request, to any
subsequent Purchaser.

     The Company shall deposit in the Escrow Account or Accounts on a
daily basis, and retain therein:

     (i) all Escrow Payments collected on account of the Mortgage Loans, for
the purpose of effecting timely payment of any such items as required under
the terms of this Agreement; and

     (ii) all amounts representing Insurance Proceeds or Condemnation Proceeds
which are to be applied to the restoration or repair of any Mortgaged
Property.

     The Company shall make withdrawals from the Escrow Account only to effect
such payments as are required or permitted under this Agreement, as set forth
in Section 4.07. The Company shall be entitled to retain any interest paid on
funds deposited in the Escrow Account by the depository institution, other
than interest on escrowed funds required by law to be paid to the Mortgagor.
To the extent required by law, the Company shall pay interest on escrowed
funds to the Mortgagor notwithstanding that the Escrow Account may be
non-interest bearing or that interest paid thereon is insufficient for such
purposes.

     Section 4.07 Permitted Withdrawals From Escrow Account.

     Withdrawals from the Escrow Account or Accounts may be made by the
Company only:

     (i) to effect timely payments of ground rents, taxes, assessments, water
rates, mortgage insurance premiums, condominium charges, fire, flood and
hazard insurance premiums or other items constituting Escrow Payments for the
related Mortgage;

     (ii) to reimburse the Company for any Servicing Advances made by the
Company pursuant to Section 4.08 with respect to a related Mortgage Loan, but
only from amounts received on the related Mortgage Loan which represent late
collections of Escrow Payments thereunder;

     (iii) to refund to any Mortgagor any funds found to be in excess of the
amounts required under the terms of the related Mortgage Loan;

     (iv) for transfer to the Custodial Account and application to reduce the
principal balance of the Mortgage Loan in accordance with the terms of the
related Mortgage and Mortgage Note;

     (v) for application to restoration or repair of the Mortgaged Property in
accordance with the procedures outlined in Section 4.14;

     (vi) to pay to the Company, or any Mortgagor to the extent required by
law, any interest paid on the funds deposited in the Escrow Account;

     (vii) to withdraw funds deposited in error in the Escrow Account; and

     (viii) to clear and terminate the Escrow Account on the termination of
this Agreement.

     Section 4.08 Maintenance of Tax, Insurance, Other Charge Records.

     With respect to each Mortgage Loan, the Company shall maintain accurate
records reflecting the status of ground rents, taxes, assessments, water
rates, sewer rents, and the charges which are or may become a lien upon the
Mortgaged Property and the status of fire, flood and hazard insurance coverage
and with respect to each Mortgage Loan which provides for Escrow Payments, the
Company shall obtain, from time to time, all bills for the payment of such
charges (including renewal premiums) and shall effect payment thereof prior to
the applicable penalty or termination date, employing for such purpose
deposits of the Mortgagor in the Escrow Account which shall have been
estimated and accumulated by the Company in amounts sufficient for such
purposes, as allowed under the terms of the Mortgage. To the extent that a
Mortgage does not provide for Escrow Payments, the Company shall make a
Servicing Advance from its own funds to effect payment for such charges in
accordance with Accepted Servicing Practices.

     Section 4.09 Protection of Accounts.

     The Company may transfer the Custodial Account or the Escrow Account to a
different Qualified Depository from time to time. Such transfer shall be made
only upon obtaining the consent of the Purchaser, which consent shall not be
withheld unreasonably.

     The Company shall bear any expenses, losses or damages sustained by the
Purchaser because the Custodial Account or Escrow Account is not a demand
deposit account.

     Section 4.10 Maintenance of Hazard Insurance

     The Company shall cause to be maintained for each Mortgage Loan hazard
insurance such that all buildings upon the Mortgaged Property are insured by a
FNMA or FHLMC acceptable insurer against loss by fire, hazards of extended
coverage and such other hazards as are customary in the area where the
Mortgaged Property is located, in an amount which is at least equal to the
lesser of (i) the maximum insurable value of the improvements securing such
Mortgage Loan and (ii) the greater of (a) the outstanding principal balance of
the Mortgage Loan and (b) an amount such that the proceeds thereof shall be
sufficient to prevent the Mortgagor or the loss payee from becoming a
co-insurer.

     If upon origination of the Mortgage Loan, the related Mortgaged Property
was located in an area identified in the Federal Register by the Flood
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 with a generally acceptable insurance carrier in
an amount representing coverage equal to the lesser of (i) the minimum amount
required, under the terms of coverage, to compensate for any damage or loss on
a replacement-cost basis or the unpaid balance of the Mortgage Loan if
replacement coverage is not available for the type of building insured) and
(ii) the maximum amount of insurance which is available under the Flood
Disaster Protection Act of 1973, as amended.

     If a Mortgage is secured by a unit in a condominium, the Company shall
have received a certificate of insurance evidencing a master policy held by
the owner's association and naming the Company as loss payee.

     In the event that the Purchaser or the Company shall determine that the
Mortgaged Property (or, in the case of a Cooperative Loan, the related
Cooperative Unit) should be insured against loss or damage by hazards and
risks not covered by the insurance required to be maintained by the Mortgagor
pursuant to the terms of the Mortgage, the Company shall communicate and
consult with the Mortgagor with respect to the need for such insurance and
bring to the Mortgagor's attention the desirability of protection of the
Mortgaged Property.

     All policies required hereunder shall name the Company as loss payee and
shall be endorsed with standard mortgagee clauses, which shall provide for at
least 30 days' prior written notice of any cancellation, reduction in amount
or material change in coverage.

     The Company shall not interfere with the Mortgagor's freedom of choice in
selecting either his insurance carrier or agent; provided, however, that the
Company shall not accept any such insurance policies from insurance companies
unless such companies satisfy the requirements of FNMA or FHLMC and are
licensed to do business in the jurisdiction in which the Mortgaged Property is
located. The Company shall determine that such policies provide sufficient
risk coverage and amounts, that they insure the property owner, and that they
properly describe the property address. The Company shall furnish to the
Mortgagor a formal notice of expiration of any such insurance in sufficient
time for the Mortgagor to arrange for renewal coverage by the expiration date.

     Pursuant to Section 4.04, any amounts collected by the Company under
any such policies (other than amounts to be deposited in the Escrow Account
and applied to the restoration or repair of the related Mortgaged Property
(or, in the case of a Cooperative Loan, the related Cooperative Unit), or
property acquired in liquidation of the Mortgage Loan, or to be released to
the Mortgagor, in accordance with the Company's normal servicing procedures as
specified in Section 4.14) shall be deposited in the Custodial Account subject
to withdrawal pursuant to Section 4.05.

     Section 4.11 Maintenance of Mortgage Impairment Insurance.

     The Company shall maintain a blanket policy insuring against losses
arising from fire and hazards covered under extended coverage on any or all of
the Mortgage Loans and, to the extent such policy provides coverage in an
amount equal to the amount required pursuant to Section 4.10 and otherwise
complies with all other requirements of Section 4.10, it shall conclusively be
deemed to have satisfied its obligations as set forth in Section 4.10. Any
amounts collected by the Company under any such policy relating to a Mortgage
Loan shall be deposited in the Custodial Account subject to withdrawal
pursuant to Section 4.05. Such policy may contain a deductible clause, in
which case, in the event that there shall not have been maintained on the
related Mortgaged Property a policy complying with Section 4.10, and there
shall have been a loss which would have been covered by such policy, the
Company shall deposit in the Custodial Account at the time of such loss the
amount not otherwise payable under the blanket policy because of such
deductible clause, such amount to deposited from the Company's funds, without
reimbursement therefor. Upon request of the Purchaser, the Company shall cause
to be delivered to such Purchaser a certified true copy of such policy and a
statement from the insurer thereunder that such policy shall in no event be
terminated or materially modified without thirty (30) days' prior written
notice to the Purchaser.

     Section 4.12 Maintenance of Fidelity Bond and Errors and Omissions
Insurance

     The Company or its corporate parent shall maintain on behalf of the
Company with responsible companies, at its own expense, a blanket Fidelity
Bond and an Errors and Omissions Insurance Policy, with broad coverage on all
officers, employees or other persons acting in any capacity requiring such
persons to handle funds, money, documents or papers relating to the Mortgage
Loans ("Company Employees"). Any such Fidelity Bond and Errors and Omissions
Insurance Policy shall be in the form of the Mortgage Banker's Blanket Bond
and shall protect and insure the Company against losses, including forgery,
theft, embezzlement, fraud, errors and omissions and negligent acts of such
Company Employees. Such Fidelity Bond and Errors and Omissions Insurance
Policy also shall protect and insure the Company against losses in connection
with the release or satisfaction of a Mortgage Loan without having obtained
payment in full of the indebtedness secured thereby. No provision of this
Section 4.12 requiring such Fidelity Bond and Errors and Omissions Insurance
Policy shall diminish or relieve the Company from its duties and obligations
as set forth in this Agreement. The minimum coverage under any such bond and
insurance policy shall be at least equal to the corresponding amounts required
by FNMA in the FNMA Mortgage-Backed Securities Selling and Servicing Guide or
by FHLMC in the FHLMC Sellers' & Servicers' Guide. Upon the request of the
Purchaser, the Company shall cause to be delivered to the Purchaser a
certified true copy of such fidelity bond and insurance policy and a statement
from the surety and the insurer that such fidelity bond and insurance policy
shall in no event be terminated or materially modified without thirty (30)
days' prior written notice to the Purchaser.

     Section 4.13 Inspections.

     The Company shall inspect the Mortgaged Property as often as deemed
necessary by the Company to assure itself that the value of the Mortgaged
Property is being preserved. In addition, if any Mortgage Loan is more than
sixty (60) days delinquent, the Company immediately shall inspect the
Mortgaged Property and shall conduct subsequent inspections in accordance with
Accepted Servicing Practices. The Company shall keep a written report of each
such inspection.

     Section 4.14 Restoration of Mortgaged Property

     The Company need not obtain the approval of the Purchaser prior to
releasing any Insurance Proceeds or Condemnation Proceeds to the Mortgagor to
be applied to the restoration or repair of the Mortgaged Property if such
release is in accordance with Accepted Servicing Practices. At a minimum, the
Company shall comply with the following conditions in connection with any such
release of Insurance Proceeds or Condemnation Proceeds:

     (i) the Company shall receive satisfactory independent verification of
completion of repairs and issuance of any required approvals with respect
thereto;

     (ii) the Company shall take all steps necessary to preserve the priority
of the lien of the Mortgage, including, but not limited to requiring waivers
with respect to mechanics' and materialmen's liens; and

     (iii) pending repairs or restoration, the Company shall place the
Insurance Proceeds or Condemnation Proceeds in the Escrow Account.

     If the Purchaser is named as an additional loss payee, the Company is
hereby empowered to endorse any loss draft issued in respect of such a claim
in the name of the Purchaser.

     Section 4.15 Title, Management and Disposition of REO Property.

     In the event that title to any Mortgaged Property is acquired in
foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale
shall be taken in the name of the Purchaser, or in the event the Purchaser is
not authorized or permitted to hold title to real property in the state where
the REO Property is located, or would be adversely affected under the "doing
business" or tax laws of such state by so holding title, the deed or
certificate of sale shall be taken in the name of such Person or Persons as
shall be consistent with an Opinion of Counsel obtained by the Company from
any attorney duly licensed to practice law in the state where the REO Property
is located. The Person or Persons holding such title other than the Purchaser
shall acknowledge in writing that such title is being held as nominee for the
Purchaser.

     The Company shall manage, conserve, protect and operate each REO Property
for the Purchaser solely for the purpose of its prompt disposition and sale.
The Company, either itself or through an agent selected by the Company, shall
manage, conserve, protect and operate the REO Property in the same manner that
it manages, conserves, protects and operates other foreclosed property for its
own account, and in the same manner that similar property in the same locality
as the REO Property is managed. The Company shall attempt to sell the same
(and may temporarily rent the same for a period not greater than one year,
except as otherwise provided below) on such terms and conditions as the
Company deems to be in the best interest of the Purchaser.

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

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

     The Company shall also maintain on each REO Property fire and hazard
insurance with extended coverage in an amount which is at least equal to the
maximum insurable value of the improvements which are part of such property,
liability insurance and, to the extent required and available under the Flood
Disaster Protection Act of 1973, as amended, flood insurance in the amount
required above.

     The disposition of REO Property shall be carried out by the Company at
such price, and upon such terms and conditions, as the Company deems to be in
the best interests of the Purchaser. The proceeds of sale of the REO Property
shall be promptly deposited in the Custodial Account. As soon as practical
thereafter, the expenses of such sale shall be paid and the Company shall
reimburse itself for any related unreimbursed Servicing Advances, unpaid
Servicing Fees and unreimbursed Monthly Advances made pursuant to Section
5.03, and on the Remittance Date immediately following the Principal
Prepayment Period in which such sale proceeds are received the net cash
proceeds of such sale remaining in the Custodial Account shall be distributed
to the Purchaser.

     The Company shall withdraw from the Custodial Account funds necessary for
the proper operation, management and maintenance of each REO Property,
including the cost of maintaining any hazard insurance pursuant to Section
4.10 and the fees of any managing agent of the Company, a Subservicer, or the
Company itself. The REO management fee shall be an amount that is reasonable
and customary in the area where the Mortgaged Property is located. The Company
shall make monthly distributions on each Remittance Date to the Purchaser of
the net cash flow from the REO Property (which shall equal the revenues from
such REO Property net of the expenses described in this Section 4.15 and of
any reserves reasonably required from time to time to be maintained to satisfy
anticipated liabilities for such expenses).

     Section 4.16 Real Estate Owned Reports.

     Together with the statement furnished pursuant to Section 5.02, the
Company shall furnish to the Purchaser on or before the Remittance Date each
month a statement with respect to any REO Property covering the operation of
such REO Property for the previous month and the Company's efforts in
connection with the sale of such REO Property and any rental of such REO
Property incidental to the sale thereof for the previous month. That statement
shall be accompanied by such other information as the Purchaser shall
reasonably request.

     Section 4.17 Liquidation Reports.

     Upon the foreclosure sale of any Mortgaged Property or the acquisition
thereof by the Purchaser pursuant to a deed in lieu of foreclosure, the
Company shall submit to the Purchaser a liquidation report with respect to
such Mortgaged Property.

     Section 4.18 Notification of Adjustments.

     With respect to each Mortgage Loan, the Company shall adjust the Mortgage
Interest Rate on the related Interest Rate Adjustment Date in compliance with
requirements of applicable law and the related Mortgage and Mortgage Note. The
Company shall execute and deliver any and all necessary notices required under
applicable law and the terms of the related Mortgage Note and Mortgage
regarding the Mortgage Interest Rate adjustments. The Company shall promptly,
upon written request therefor, deliver to the Purchaser such notifications and
any additional applicable data regarding such adjustments and the methods used
to calculate and implement such adjustments. Upon the discovery by the Company
or the receipt of notice from the Purchaser that the Company has failed to
adjust a Mortgage Interest Rate in accordance with the terms of the related
Mortgage Note, the Company shall immediately deposit in the Custodial Account
from its own funds the amount of any interest loss or deferral caused to the
Purchaser thereby.

     Section 4.19 Reports of Foreclosures and Abandonments of Mortgaged
Property

     Following the foreclosure sale or abandonment of any Mortgaged Property,
the Company shall report such foreclosure or abandonment as required pursuant
to Section 6050J of the Code.


                                   ARTICLE V

                             PAYMENTS TO PURCHASER

     Section 5.01 Remittances.

     On each Remittance Date the Company shall remit by wire transfer of
immediately available funds to the Purchaser the sum of (a) all amounts
deposited in the Custodial Account as of the close of business on the
Determination Date (net of charges against or withdrawals from the Custodial
Account pursuant to Section 4.05 ), (b) all amounts, if any, which the Company
is obligated to deposit into the Custodial Account pursuant to Section 5.03,
and (c) any amounts payable with respect to Qualified Substitute Mortgage
Loans, but not including, (i) any amounts attributable to Principal
Prepayments received after the immediately preceding Principal Prepayment
Period, (ii) any Liquidation Proceeds and Insurance Proceeds received after
the immediately preceding Prepayment Period, and (iii) any amounts
attributable to Monthly Payments collected but due on a Due Date or Dates
subsequent to the first day of the month of such Remittance Date, all of which
amounts together with any additional interest required to be deposited into a
Custodial Account in connection with a Principal Prepayment in accordance with
Section 4.04(viii), shall be remitted on the next succeeding Remittance Date.

     With respect to any remittance received by the Purchaser after the second
Business Day following the Remittance Date on which such payment was due, the
Company shall pay to the Purchaser interest on any such late payment at an
annual rate equal to the Prime Rate, adjusted as of the date of each change,
plus three (3) percentage points, but in no event greater than the maximum
amount permitted by applicable law. Such interest shall be deposited in the
Custodial Account by the Company on the date such late payment is made and
shall cover the period commencing with the day following such second Business
Day and ending with the Business Day on which such payment is made, both
inclusive. Such interest shall be remitted along with the distribution payable
on the next succeeding Remittance Date. The payment by the Company of any such
interest shall not be deemed an extension of time for payment or a waiver of
any Event of Default by the Company.

     Section 5.02 Statements to Purchaser.

     Not later than the Remittance Date, the Company shall furnish to the
Purchaser a Monthly Remittance Advice, with a trial balance report attached
thereto, in the form of Exhibit F annexed hereto as to the preceding
remittance and the period ending on the preceding Determination Date.

     In addition, not more than sixty (60) days after the end of each
calendar year, the Company shall furnish to each Person who was a Purchaser at
any time during such calendar year an annual statement in accordance with the
requirements of applicable federal income tax law as to the aggregate of
remittances for the applicable portion of such year.

     Such obligation of the Company shall be deemed to have been satisfied to
the extent that substantially comparable information shall be provided by the
Company pursuant to any requirements of the Code as from time to time are in
force.

     The Company shall prepare and file any and all tax returns, information
statements or other filings relating to the period of time prior to the sale
of the Mortgage Loans by the Company to the Purchaser required to be delivered
to any governmental taxing authority pursuant to any applicable law with
respect to the Mortgage Loans. In addition, the Company shall provide the
Purchaser with such information concerning the Mortgage Loans as is necessary
for the Purchaser to prepare its federal income tax returns.

     Section 5.03 Monthly Advances by Company.

     On the Business Day immediately preceding each Remittance Date, the
Company shall deposit in the Custodial Account from its own funds an amount
equal to all Monthly Payments (with interest adjusted to the Mortgage Loan
Remittance Rate) which were due on the Mortgage Loans during the applicable
Due Period and which were delinquent at the close of business on the
immediately preceding Determination Date or which were deferred pursuant to
Section 4.01. The Company's obligation to make such Monthly Advances as to any
Mortgage Loan will continue (i) through the last Monthly Payment due prior to
the payment in full of the Mortgage Loan, (ii) through the last Remittance
Date prior to the Remittance Date for the distribution of all Liquidation
Proceeds or other payments or recoveries (including Insurance Proceeds and
Condemnation Proceeds) with respect to the Mortgage Loans or (iii) until the
Company deems a future advance to be a Nonrecoverable Advance, whichever of
(i) (ii) or (iii) occurs first.

                                  ARTICLE VI

                         GENERAL SERVICING PROCEDURES

     Section 6.01 Transfers of Mortgaged Property.

     The Company shall use its best efforts to enforce any "due-on-sale"
provision contained in any Mortgage or Mortgage Note and to deny assumption by
the person to whom the Mortgaged Property has been or is about to be sold
whether by absolute conveyance or by contract of sale, and whether or not the
Mortgagor remains liable on the Mortgage and the Mortgage Note. When the
Mortgaged Property has been conveyed by the Mortgagor, the Company shall, to
the extent it has knowledge of such conveyance, exercise its right to
accelerate the maturity of such Mortgage Loan under the "due-on-sale" clause
applicable thereto; provided, however, that the Company shall not exercise
such rights if prohibited by law from doing so.

     If the Company reasonably believes it is unable under applicable law to
enforce such "due-on-sale" clause, the Company shall enter into (i) an
assumption and modification agreement with the person to whom such property
has been conveyed, pursuant to which such person becomes liable under the
Mortgage Note and the original Mortgagor remains liable thereon or (ii) in the
event the Company is unable under applicable law to require that the original
Mortgagor remains liable under the Mortgage Note and the Company has the prior
consent of the primary mortgage guaranty insurer, a substitution of liability
agreement with the purchaser of the Mortgaged Property pursuant to which the
original Mortgagor is released from liability and the purchaser of the
Mortgaged Property is substituted as Mortgagor and becomes liable under the
Mortgage Note. If an assumption fee is collected by the Company for entering
into an assumption agreement, a portion of such fee, up to an amount equal to
one-half of one percent (0.5%) of the outstanding principal balance of the
related Mortgage Loan, will be retained by the Company as additional servicing
compensation, and any portion thereof in excess of one-half of one percent
(0.5%) shall be deposited in the Custodial Account for the benefit of the
Purchaser. In connection with any such assumption, neither the Mortgage
Interest Rate borne by the related Mortgage Note, the term of the Mortgage
Loan nor the outstanding principal amount of the Mortgage Loan shall be
changed.

     To the extent that any Mortgage Loan is assumed, the Company shall
inquire diligently into the creditworthiness of the proposed transferee, and
shall use the Company's Summary of Underwriting Guidelines attached hereto as
Exhibit A-1. If the credit of the proposed transferee does not meet such
underwriting criteria, the Company diligently shall, to the extent permitted
by the Mortgage or the Mortgage Note and by applicable law, accelerate the
maturity of the Mortgage Loan.

     Section 6.02 Satisfaction of Mortgages and Release of Mortgage Files.

     Upon the payment in full of any Mortgage Loan, or the receipt by the
Company of a notification that payment in full will be escrowed in a manner
customary for such purposes, the Company shall notify the Purchaser in the
Monthly Remittance Advice as provided in Section 5.02, and may request the
release of any Mortgage Loan Documents.

     Except as permitted pursuant to Section 4.01, if (i) the Company
satisfies or releases a Mortgage without first having obtained payment in full
of the indebtedness secured by the Mortgage or notification that payment in
full will be escrowed in a manner customary for such purposes or (ii) should
the Company otherwise prejudice any rights the Purchaser may have under the
mortgage instruments, upon written demand of the Purchaser, the Company shall
repurchase the related Mortgage Loan at the Repurchase Price by deposit
thereof in the Custodial Account within two (2) Business Days of receipt of
such demand by the Purchaser. The Company shall maintain the Fidelity Bond and
Errors and Omissions Insurance Policy as provided for in Section 4.12 insuring
the Company against any loss it may sustain with respect to any Mortgage Loan
not satisfied in accordance with the procedures set forth herein.

     Section 6.03 Servicing Compensation.

     As compensation for its services hereunder, the Company shall be entitled
to withdraw from the Custodial Account or to retain from interest payments on
the Mortgage Loans the amount of its Servicing Fee. The Servicing Fee shall be
payable monthly and shall be computed on the basis of the same unpaid
principal balance and for the same period with respect to which any related
interest payment on a Mortgage Loan is computed. The Servicing Fee shall be
payable only at the time of and with respect to those Mortgage Loans for which
payment is in fact made of the entire amount of the Monthly Payment. The
obligation of the Purchaser to pay the Servicing Fee is limited to, and
payable solely from, the interest portion of such Monthly Payments collected
by the Company. The aggregate of the Servicing Fees for any months with
respect to the Mortgage Loans shall be reduced by any amount payable by the
Company with respect to such month pursuant to Section 4.04(viii).

     Additional servicing compensation in the form of assumption fees, to the
extent provided in Section 6.01, and late payment charges shall be retained by
the Company to the extent not required to be deposited in the Custodial
Account. The Company shall be required to pay all expenses incurred by it in
connection with its servicing activities hereunder and shall not be entitled
to reimbursement thereof except as specifically provided for herein.

     Section 6.04 Annual Statement as to Compliance.

     The Company shall deliver to the Purchaser, on or before March 31st each
year beginning March 31, 1999, an Officer's Certificate, stating that (i) a
review of the activities of the Company during the preceding calendar year and
of performance under this Agreement has been made under such officer's
supervision, and (ii) the Company has complied fully with the provisions of
Article II and Article IV, and (iii) to the best of such officer's knowledge,
based on such review, the Company has fulfilled all of its obligations under
this Agreement throughout such year, or, if there has been a default in the
fulfillment of any such obligation, specifying each such default known to such
officer and the nature and status thereof and the action being taken by the
Company to cure such default.

     Section 6.05 Annual Independent Public Accountants' Servicing Report.

     On or before March 31st of each year beginning March 31, 1999, the
Company, at its expense, shall cause a firm of independent public accountants
which is a member of the American Institute of Certified Public Accountants to
furnish a statement to the Purchaser to the effect that such firm has examined
certain documents and records relating to the servicing of the Mortgage Loans,
on the basis of such examination conducted substantially in compliance with
the Single Attestation Program for Mortgage Bankers, nothing has come to their
attention which would indicate that such servicing has not been conducted in
compliance therewith, except for (i) such exceptions as such firm shall
believe to be immaterial, and (ii) such other exceptions as shall be set forth
in such statement.

     Section 6.06 Right to Examine Company Records.

     The Purchaser shall have the right to examine and audit any and all of
the books, records, or other information of the Company, whether held by the
Company or by another on its behalf, with respect to or concerning this
Agreement or the Mortgage Loans, during business hours or at such other times
as may be reasonable under applicable circumstances, upon reasonable advance
notice.


                                  ARTICLE VII

                             COMPANY TO COOPERATE

     Section 7.01 Provision of Information.

     During the term of this Agreement, the Company shall furnish to the
Purchaser such periodic, special, or other reports or information and copies
or originals of any documents contained in the Servicing File for each
Mortgage Loan, whether or not provided for herein, as shall be necessary,
reasonable, or appropriate with respect to the Purchaser, any regulatory
requirement pertaining to the Purchaser or the purposes of this Agreement. All
such reports, documents or information shall be provided by and in accordance
with all reasonable instructions and directions which the Purchaser may give.

     The Company shall execute and deliver all such instruments and take all
such action as the Purchaser may reasonably request from time to time, in
order to effectuate the purposes and to carry out the terms of this Agreement.

     Section 7.02 Financial Statements; Servicing Facilities.

     The Company may make available to a prospective Purchaser a Consolidated
Statement of Operations of Mellon Bank Corporation for the most recently
completed five fiscal years for which such a statement is available, as well
as a Consolidated Statement of Condition at the end of the last two fiscal
years covered by such Consolidated Statement of Operations. The Company also
shall make available any comparable interim statements to the extent any such
statements have been prepared by or on behalf of the Company (and are
available upon request to members or stockholders of the Company or to the
public at large). Upon Purchaser's request, the Company shall furnish promptly
to the Purchaser copies of the statement specified above.

     Upon Purchaser's request, the Company also shall make available to
Purchaser a knowledgeable financial or accounting officer for the purpose of
answering questions respecting recent developments affecting the Company or
the financial statements of the Company.


                                 ARTICLE VIII

                                  THE COMPANY

     Section 8.01 Third Party Claims.

     The Company immediately shall notify the Purchaser if a claim is made by
a third party with respect to this Agreement or the Mortgage Loans, assume
(with the prior written consent of the Purchaser) the defense of any such
claim and pay all expenses in connection therewith, including reasonable and
necessary counsel fees, and promptly pay, discharge and satisfy any judgment
or decree which may be entered against it or the Purchaser in respect of such
claim. The Company shall follow any written instructions received from the
Purchaser in connection with such claim. The Purchaser promptly shall
reimburse the Company for all amounts advanced by it pursuant to the preceding
sentence except when the claim is in any way related to the Company's
indemnification pursuant to Section 3.03 and the Purchaser has notified the
Company of such third party claim as provided herein, or to the failure of the
Company to service and administer the Mortgage Loans in strict compliance with
the material terms of this Agreement and such failure of the Company is not
attributable to acts or omissions by the Purchaser. In the event of claims
relating to the Company's indemnification pursuant to Section 3.03, the
Purchaser immediately shall notify the Company of any claim by a third party.

     Section 8.02 Merger or Consolidation of the Company.

     The Company shall obtain and preserve its qualification to do business as
a foreign corporation in each jurisdiction in which such qualification is or
shall be necessary to protect the validity and enforceability of this
Agreement or any of the Mortgage Loans and to perform its duties under this
Agreement.

     Any person into which the Company may be merged or consolidated, or any
corporation resulting from any merger, conversion or consolidation to which
the Company shall be a party, or any Person succeeding to the business of the
Company, shall be the successor of the Company hereunder, without the
execution or filing of any paper or any further act on the part of any the
parties hereto, anything herein to the contrary notwithstanding; provided,
however, that the successor or surviving Person shall be an institution (i)
whose deposits are insured by the FDIC through the BIF or the SAIF, (ii) which
is or is affiliated with a FNMA-approved servicer in good standing, and (iii)
has a net worth of at least $15 million.

     Section 8.03 Limitation on Liability of Company and Others.

     Neither the Company nor any of the parents, affiliates, subsidiaries,
directors, officers, employees or agents of the Company shall be under any
liability to the Purchaser 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
Company or any such Person against any breach of warranties or representations
made herein, or failure to perform its obligations in strict compliance with
any standard of care set forth in this Agreement, or any liability which would
otherwise be imposed by reason of any breach of the terms and conditions of
this Agreement. The Company and any parent, affiliate, subsidiary, director,
officer, employee or agent of the Company 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 Company shall not be under any
obligation to appear in, prosecute or defend any legal action which is not
incidental to its duties to service the Mortgage Loans in accordance with this
Agreement and which in its opinion may involve it in any expense or liability;
provided, however, that the Company may, with the consent of the Purchaser,
undertake any such action which it may deem necessary or desirable in respect
to this Agreement and the rights and duties of the parties hereto. In such
event, the Company shall be entitled to reimbursement from the Purchaser of
the reasonable legal expenses and costs of such action.

     Section 8.04 Limitation on Resignation and Assignment by Company.

     The Purchaser has entered into this Agreement with the Company and any
subsequent Purchaser will purchase the Mortgage Loans in reliance upon the
representations as to the adequacy of its servicing facilities, plant,
personnel, records and procedures, its integrity, reputation and financial
standing, and the continuance thereof. Therefore, the Company shall not assign
this Agreement or the servicing hereunder nor shall it delegate its rights or
duties hereunder or any portion hereof (to other than a Subservicer) or sell
or otherwise dispose of all or substantially all of its property or assets
without the prior written consent of the Purchaser (which consent shall be
granted or withheld in the sole discretion of the Purchaser) except that the
Company may assign this Agreement to a successor, parent, or affiliated entity
without the prior written consent of the Purchaser in accordance with Section
8.02.

     The Company shall not resign from the obligations and duties hereby
imposed on it except by mutual consent of the Company and the Purchaser or
upon the determination that its duties hereunder are no longer permissible
under applicable law and such incapacity cannot be cured by the Company by
reasonable means. Any such determination permitting the resignation of the
Company shall be evidenced by an Opinion of Counsel to such effect delivered
to the Purchaser, which Opinion of Counsel shall be in form and substance
acceptable to the Purchaser. No such resignation shall become effective unless
(i) the Company also resigns from the Amended and Restated Mortgage Loan Sale,
Warranties and Servicing Agreement, dated as of April 1, 1998 (the "First Sale
and Servicing Agreement") between the Company and the Purchaser, which amends
and restates the Mortgage Loan Sale, Warranties and Servicing Agreement, dated
as of January 1, 1998, between the Company and the Purchaser and (ii) until a
successor shall have assumed the Company's responsibilities and obligations
hereunder and under the First Sale and Servicing Agreement in the manner
provided in Section 11.01 in each of this Agreement and the First Sale and
Servicing Agreement.

     Without in any way limiting the generality of this Section 8.04, and
except as otherwise permitted under this Agreement, in the event that the
Company either shall assign this Agreement or the servicing responsibilities
hereunder or delegate its duties hereunder or any portion thereof (to other
than a Subservicer) or sell or otherwise dispose of all or substantially all
of its property or assets, without the prior written consent of the Purchaser,
then the Purchaser shall have the right to terminate this Agreement and the
First Sale and Servicing Agreement upon notice given as set forth in Section
11.05 in each of this Agreement and the First Sale and Servicing Agreement,
without any payment of any penalty or damages and without any liability
whatsoever to the Company or any third party.


                                  ARTICLE IX

                                    DEFAULT

     Section 9.01 Events of Default.

     Each of the following shall constitute an Event of Default on the part of
the Company:

     (i) any failure by the Company to remit to the Purchaser any payment
required to be made under the terms of this Agreement which continues
unremedied for a period of five (5) Business Days after the date upon which
written notice of such failure, requiring the same to be remedied, shall have
been given to the Company by the Purchaser; or

     (ii) failure by the Company duly to observe or perform in any material
respect any other of the covenants or agreements on the part of the Company
set forth in this Agreement or in the Custodial Agreement which continues
unremedied for a period of thirty (30) days after the date on which written
notice of such failure, requiring the same to be remedied, shall have been
given to the Company by the Purchaser (or by the Custodian); or

     (iii) failure by the Company to maintain any license required to do

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.

     This Agreement shall terminate upon either: (i) the later of the
final payment or other liquidation (or any advance with respect thereto) of
the last Mortgage Loan or the disposition of any REO Property with respect to
the last Mortgage Loan and the remittance of all funds due hereunder; or (ii)

                                  ARTICLE XI

                           MISCELLANEOUS PROVISIONS

     Section 11.01 Successor to Company.

     Prior to termination of the Company's responsibilities and duties under
this Agreement pursuant to Sections 8.04, 9.01 or 10.01 (ii) the Purchaser
shall (i) succeed to and assume all of the Company's responsibilities, rights,
duties and obligations under this Agreement, or (ii) appoint a successor
having the characteristics set forth in clauses (i) through (iii) of Section
8.02 and which shall succeed to all rights and assume all of the
responsibilities, duties and liabilities of the Company under this Agreement
prior to the termination of Company's responsibilities, duties and liabilities
under this Agreement. In connection with such appointment and assumption, the
Purchaser may make such arrangements for the compensation of such successor
(not to exceed the Servicing Fee) out of payments on Mortgage Loans as it and
such successor shall agree. In the event that the Company's duties,
responsibilities and liabilities under this Agreement should be terminated
pursuant to the aforementioned sections, the Company shall discharge such
duties and responsibilities during the period from the date it acquires
knowledge of such termination until the effective date thereof with the same
degree of diligence and prudence which it its obligated to exercise under this
Agreement, and shall take no action whatsoever that might impair or prejudice
the rights or financial condition of its successor. The resignation or removal
of the Company pursuant to the aforementioned sections shall not become
effective until a successor shall be appointed pursuant to this Section 11.01
and shall in no event relieve the Company of the representations and
warranties made pursuant to Sections 3.01 and 3.02 and the remedies available
to the Purchaser under Section 3.03, it being understood and agreed that the
provisions of such Sections 3.01 and 3.02 shall be applicable to the Company
notwithstanding any such sale, assignment, resignation or termination of the
Company, or the termination of this Agreement.

     Any successor appointed as provided herein shall execute, acknowledge and
deliver to the Company and to the Purchaser an instrument accepting such
appointment, wherein the successor shall make the representations and
warranties set forth in Section 3.01, except for subsections (h), (i) and (j)
thereof, whereupon such successor shall become fully vested with all the
rights, powers, duties, responsibilities, obligations and liabilities of the
Company, with like effect as if originally named as a party to this Agreement.
Any termination or resignation of the Company or termination of this Agreement
pursuant to Section 8.04, 9.01 or 10.01 shall not affect any claims that any
Purchaser may have against the Company arising out of the Company's actions or
failure to act prior to any such termination or resignation.

     The Company shall deliver promptly to the successor servicer the funds in
the Custodial Account, REO Account and Escrow Account and all Mortgage Files
and related documents and statements held by it hereunder and the Company
shall account for all funds and shall execute and deliver such instruments and
do such other things as may reasonably be required to more fully and
definitively vest in the successor all such rights, powers, duties,
responsibilities, obligations and liabilities of the Company.

     Section 11.02 Amendment.

     Capitalized terms used in this Section 11.02 but not defined in this
Agreement shall have the meanings assigned to them in the Trust Agreement.

     (a) This Agreement may be amended from time to time by the Company and
the Purchaser (ii) to cure any ambiguity, (ii) 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 the Trust Agreement, nor
shall such amendment effected pursuant to clause (iii) of such sentence
adversely affect in any material respect the interest of any Holder of any
Certificates issued by the Trust. Prior to entering into any amendment
pursuant to this paragraph, the Purchaser 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 of
Certificates, if the Purchaser 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 Company
and the Purchaser with the consent of the Holders of not less that 66K% of the
Class Certificate Principal Amount (or Aggregate Notional Amount) of each
Class of Certificates affected thereby for the purpose of adding any
provisions to or changing in any manner or deleting any of the provisions of
this Agreement or of modifying in any manner the rights of the Holders (except
as such additions, changes, deletions or modifications may be permitted under
Section 11.02(a) above); provided, however, that no such amendment shall be
made unless the Purchaser receives an Opinion of Counsel, at the expense of
the party requesting the change, that such change will not adversely affect
the status of any REMIC created pursuant to the Trust Agreement as a REMIC or
cause a tax to be imposed on any such REMIC.

     Section 11.03 Governing Law.

     This Agreement shall be governed by and construed in accordance with the
laws of the Commonwealth of Massachusetts and the obligations, rights and
remedies of the parties hereunder shall be determined in accordance with such
laws.

     This Agreement shall continue in existence and effect until terminated as

such termination. This Agreement shall continue notwithstanding transfers of
the Mortgage Loans by the Purchaser.

     Section 11.08 Execution; Successors and Assigns.

     This Agreement may be executed in one or more counterparts and by the

     This Agreement, including all schedules and exhibits, constitutes the
entire agreement between the parties hereto with respect to the transactions
contemplated hereby and supersedes all prior discussions, understandings,
agreements and negotiations between the parties hereto with respect to such
transactions; provided, however, that the Purchase Price referred to herein
shall be the purchase price set forth in the Purchase Price and Terms Letter,
and that provision of the Purchase Price and Terms Letter shall survive for
the exclusive purpose of such cross-reference. The provisions of this
Agreement shall govern in any conflict between the terms of this Agreement and
the Purchase Price and Terms Letter.

     Section 11.10 Assignment by Purchaser.

     The Purchaser shall have the right, without the consent of the Company
but subject to the limit set forth in Section 2.02 hereof, to assign, in whole
or in part, its interest under this Agreement with respect to some or all of
the Mortgage Loans, and designate any person to exercise any rights of the
Purchaser hereunder, and the assignee or designee shall accede to the rights
and obligations hereunder of the Purchaser with respect to such Mortgage
Loans. All references to the Purchaser in this Agreement shall be deemed to
include its assignee or designee and any subsequent assignee, specifically
including the Trustee.

     Section 11.11 No Solicitation.

     From and after the Closing Date, the Company agrees that it will not take
any action or permit or cause any action to be taken by any of its agents or
affiliates, or by any independent contractors on the Company's behalf, to
personally, by telephone or mail, solicit the borrower or obligor under any
Mortgage Loan for purposes relating to the marketing of the Company's first
mortgage loan products, including to refinance a Mortgage Loan, in whole or in
part, without the prior written consent of the Purchaser, its successors and
assigns. It is understood and agreed that all rights and benefits relating to
the solicitation of any Mortgagors and the attendant rights, title and
interest in and to the list of such Mortgagors and data relating to their
Mortgages (including insurance renewal dates) shall be transferred to the
Purchaser pursuant hereto on the Closing Date and the Company shall take no
action to undermine these rights and benefits. Notwithstanding the foregoing,
it is understood and agreed that general promotions undertaken by the Company

     Section 11.12 Reconstitution.

     The Company understands and agrees that it is the intent of the Purchaser
to securitize the Mortgage Loans (i.e., to form a trust and to issue
securities evidencing interests therein). The Company agrees to review and
adhere to the terms of any agreements that may be required to facilitate such
securitization and to provide and execute such certificates, Opinions of
Counsel and other documents as may be necessary to facilitate such
securitization, it being understood that any such agreements and other
documents will not impose upon the Company any obligations more burdensome
than those contained in this Agreement. It is further understood that the
Purchaser has agreed to reimburse the Company for its reasonable attorneys'
fees and other costs incurred in connection with such securitization.

     The Company agrees that, notwithstanding anything to the contrary in the
Purchase Price and Terms Letter or in this Agreement (including Section 11.09
hereof), the provisions of Sections 3 and 12 of the Purchase Price and Terms
Letter shall survive the execution of this Agreement and shall remain in
effect.

     IN WITNESS WHEREOF, the Company and the Purchaser have caused their names
to be signed hereto by their respective officers thereunto duly authorized as

                               _____________ ____,199__


Lehman Capital, A Division of
   Lehman Brothers Holdings Inc.
3 World Financial Center
New York, NY 10285-1200


Dear Ladies and Gentlemen:

     I am Deputy General Counsel of and counsel for Boston Safe Deposit and
Trust Company (the "Seller"), in connection with the sale (the "Sale") by the
Seller of a portfolio of loans secured by residential real estate and shares
of cooperative associations (the "Loans") to Lehman Capital, A Division of
Lehman Brothers Holdings Inc. ("the Purchaser") pursuant to a Mortgage Loan
Sale, Warranties and Servicing Agreement dated as of _____________ ___, ____,
by and between the Seller and the Purchaser. Capitalized terms used but not
defined herein have the meanings ascribed to them in the Agreement.

     In connection with rendering this opinion, I have examined originals, or
copies identified to my satisfaction as being true copies of originals, of the
following, among other things:

     (a) the Mortgage Loan Sale, Warranties and Servicing Agreement;

     (b)  the Additional Pledged Collateral Custodial Agreement by and among
          the Seller, the Purchaser and [ ] ("the Custodian");

     (c)  the form of Assignment of Mortgage;

     (d)  the form of endorsement of the Mortgage Notes;

     (e)  the Charter and By-laws of the Seller; and,

     (f)  such other documents, records and papers as we have deemed necessary
          and relevant as a basis for this opinion.

     For the purposes of the opinions expressed below, I have assumed (i) the
genuineness of all signatures on original documents or instruments; (ii) the
authenticity of all documents or instruments submitted to me as originals,
(iii) the conformity to originals of all documents or instruments submitted to
me as copies; (iv) the due authorization, execution and delivery of all
documents where due authorization, execution and delivery are requisite to the
effectiveness thereof (other than the authorization, execution and delivery by
the Seller of the Agreement, as to which my opinions are expressed below); (v)
that, immediately prior to the transfer of any Loan to the Purchaser pursuant
to the Agreement, with respect to such Loan, (A) the Seller was the holder and
named payee of the Note, (B) the Seller was the mortgagee or beneficiary, as
applicable, under each related Security Instrument, and (C) the Seller was the
owner of such Loan free and clear of any and all liens, claims, encumbrances,
participation interests, equities, pledges, charges, security or other
interests of any nature; (vi) that each Note corresponding to each Loan has
been endorsed by the Seller using the form of endorsement attached hereto and
each Note so endorsed has been delivered to the Purchaser on or before the
date hereof; (vii) that the Purchaser is acquiring the Loans in good faith for
value without notice that they are overdue or have been dishonored or of any
defense against or claim to the Loans or any interest therein on the part of
any person; (viii) that there is no evidence on any of the Loan Documents of
any interest contrary to the Seller's interests under the Agreement; (ix) that
the Seller is solvent and will not be rendered insolvent by the sale of the
portfolio of Loans; and, (x) that the Seller has received payment of
reasonably equivalent value for the Loans. I have no actual knowledge that any
of the foregoing assumptions is incorrect. I also have relied to the extent I
deem proper upon written statements and certificates of public officials and,
as to various matters of fact relevant to the opinions expressed herein, I
have relied upon certificates and statements of officers of the Seller.

     On the basis of the foregoing examination, statements and assumptions and
in reliance thereon and upon consideration of applicable law, I am of the
opinion that:

     (1) The Seller is a Massachusetts trust company, duly organized, validly
existing, and in good standing under the laws of the Commonwealth of
Massachusetts and is duly authorized to transact its business.

     (2) The Seller has the requisite corporate power to execute and deliver
the Agreement and to consummate the transactions contemplated thereby. The
execution and delivery of the Agreement by the Seller and the consummation of
the transactions contemplated thereby have been duly authorized by all
necessary corporate action on the part of the Seller. The Agreement has been
duly executed and delivered by the Seller and, assuming due authorization,
execution and delivery by Purchaser and prior satisfaction of all conditions
to the obligations of each of the parties under the Agreement (or a valid
waiver thereof by such parties, as applicable), the Agreement constitutes the
legal, valid, and binding obligation of the Seller enforceable in accordance
with its terms subject only to the exceptions set forth below, and Seller has
all power, authority and right to perform and observe the terms and conditions
of such instruments.

     (3) The execution and delivery of the Agreement by the Seller does
not, and the performance of the Agreement by the Seller will not, (a) result
in a breach of or violate the Charter or By-laws of the Seller, (b) violate
(A) any statute, law, rule or regulation, or (B) to the best of my knowledge,
any order, judgment, award, administrative interpretation, injunction, writ,
or decree or the like of any court or government authority, or (C) to the best
of my knowledge, conflict with or violate any agreement, permit, license, or
other governmental authorization or approval necessary for the purchase by the
Seller of the Loans, the effect of which breach, conflict or violation would
be material and adverse to the rights of the Purchaser under the Agreement or
to the Loans. No regulatory approvals or consents are required under
Massachusetts or federal law or regulation with respect to Seller's
consummation of the transactions between Purchaser and Seller contemplated by
the Agreement.

     (4) To the best of my knowledge, there are no actions, suits,
proceedings, or governmental investigations or inquiries pending or threatened
against the Seller seeking to prevent or that, if successful, would prevent
the consummation of the transactions contemplated by the Agreement.

     (5) The Mortgages have been duly assigned and the Mortgage Notes have
been duly endorsed by a duly authorized officer of the Company as provided in
the Custodial Agreement.

     The opinion set forth in the last sentence of paragraph (2) above to the
effect that the Agreement is enforceable against Seller in accordance with its
terms, is subject to the following exceptions:

     a. Such enforceability may be limited by bankruptcy, insolvency,
receivership, conservatorship, reorganization or other similar laws now or
hereafter in effect relating to or affecting creditor's rights.

     b. Such enforceability may be limited by general equitable principles,
including, without limitation, concepts of materiality, reasonableness, good
faith and fair dealing, and the possible unavailability of specific
performance or injunctive relief, regardless of whether such enforceability is
considered in a proceeding in equity or at law.

     I hereby advise your that the opinions expressed herein are limited to
matters of federal law and the law of the Commonwealth of Massachusetts and do
not purport to cover any matters as to which any laws of any other
jurisdiction are applicable. Insofar as the opinions expressed herein are
limited to transactions between the Seller and the Purchaser, except for the
opinion I express in paragraph (5) above, I express no opinion regarding any
transaction(s) between Seller or Purchaser and any Obligor(s) evidenced by
loan applications, Notes, Mortgages, disclosures, notices or any other
instrument or documents entered into or exchanged between the Seller or
Purchaser and the Obligor(s). I am not assuming any obligation to revise or
supplement the opinions expressed above should such laws be changed by
legislative action, judicial decision, or otherwise.

     This opinion is rendered to you as the Purchaser named in the Agreement
solely in connection with the transactions contemplated therein and may not be
used or relied upon by any other person or for any other purpose without our
express prior written consent.

                                           Respectfully submitted,



                                           Marilyn K. Kolb
                                           Deputy General Counsel

                                  FORM OF OPINION OF PURCHASER'S COUNSEL

Boston Safe Deposit and Trust Company
One Boston Place
Boston, MA 02108

Dear Ladies and Gentlemen:

     I am counsel for Lehman Capital, A Division of Lehman Brothers Holdings
Inc. (the "Purchaser"), in connection with the sale (the "Sale") by Boston
Safe Deposit and Trust Company ("Seller") of a portfolio of loans secured by
residential real estate and shares of cooperative associations (the "Loans")
to Purchaser pursuant to a Mortgage Loan Sale, Warranties and Servicing
Agreement dated as of _________________ ___, _____, by and between the Seller
and the Purchaser. Capitalized terms used but not defined herein have the
meanings ascribed to them in the Agreement.

     In connection with rendering this opinion, I have examined originals, or
copies identified to my satisfaction as being true copies of originals, of the
following, among other things:

     (a) the Agreement and all exhibits and schedules thereto; and

     (b) the Charter and By-laws of the Purchaser.

     For the purposes of the opinions expressed below, I have assumed (i) the
genuineness of all signatures on original documents or instruments; (ii) the
authenticity of all documents or instruments submitted to me as originals,
(iii) the conformity to originals of all documents or instruments submitted to

pursuant to the Agreement, with respect to such Loan, (A) the Seller was the

to each Loan has been endorsed by the Seller using the form of endorsement
attached hereto and each Note so endorsed has been delivered to the Purchaser
on or before the date hereof; (vii) that the Purchaser is acquiring the Loans
in good faith for value without notice that they are overdue or have been
dishonored or of any defense against or claim to the Loans or any interest
therein on the part of any person; (viii) that there is no evidence on any of
the Loan Documents of any interest contrary to the Seller's interests under
the Agreement; (ix) that the Purchaser is solvent and will not be rendered
insolvent by the purchase of the portfolio of Loans, and (x) that the Seller

have relied to the extent I deem proper upon written statements and
certificates of public officials and, as to various matters of fact relevant

     (3) The execution and delivery of the Agreement by the Purchaser does

result in a breach of or violate the Charter or By-laws of the Purchaser, (b)
violate (A) any statute, law, rule or regulation, or (B) to the best of my
knowledge, any order, judgment, award, administrative interpretation,
injunction, writ, or decree or the like of any court or government authority,
or (C) to the best of my knowledge, conflict with or violate any agreement,
permit, concession, grant, franchise, license, or other governmental
authorization or approval necessary for the purchase by the Purchaser of the
Loans, the effect of which breach, conflict or violation would be material and
adverse to the rights of the Purchaser under the Agreement or to the Loans. No
regulatory approvals or consents are required under federal law or regulation
with respect to Purchaser's consummation of the transactions between Purchaser
and Seller contemplated by the Agreement.

     (4) To the best of my knowledge, there are no actions, suits,
proceedings, or governmental investigations or inquiries pending or threatened
against the Purchaser seeking to prevent or that, if successful, would prevent
the consummation of the transactions contemplated by the Agreement.

     The opinion set forth in the last sentence of paragraph (2) above to the

     I hereby advise your that the opinions expressed herein are limited to
matters of federal and [ ] law and do not purport to cover any matters as to
which any laws of any other jurisdiction are applicable. Insofar as the
opinions expressed herein are limited to transactions between the Seller and

should such laws be changed by legislative action, judicial decision, or

     This opinion is rendered to you as the Seller named in the Agreement
solely in connection with the transactions contemplated therein and may not be
used or relied upon by any other person or for any other purpose without our
express prior written consent.

                                        Respectfully submitted,

     NOW, THEREFORE, in consideration of the mutual undertakings herein
expressed the parties hereto hereby agree as follows:

     Section 1. Definitions.

     Notwithstanding anything herein to the contrary, Custodian shall be
fully protected in acting in accordance with directions with respect to
securities transactions (including without limitation the affirmation and/or
confirmation of such transactions) received by it through a system or
arrangement for the coordination of securities transaction settlements
operated by Depository Trust Company or by any central securities depository,
securities clearing organization or book entry system which serves to link
investment managers, securities brokers and custodian banks, pursuant to an
agreement entered into by Custodian and the Purchaser to the same extent as if
the directions were in writing.

     Section 6. Without Express Authority.

     The Custodian may, in its discretion and without express authority from
the Purchaser:

          (a) endorse for collection, in the name of the Purchaser, checks,
     drafts and other negotiable instruments; and

          (b) in general, attend to all non-discretionary details in
     connection with the sale, exchange, substitution, purchase, transfer and
     other dealings with the Additional Collateral of the Purchaser except as
     otherwise provided by proper instructions.

     Section 7. Standard of Care.

     The duties of Custodian shall only be those specifically undertaken
pursuant to this Agreement, and Custodian shall not be liable for an act or
omission of another person in carrying out any responsibility imposed upon
such person with respect to the Additional Collateral held under this
Agreement whether such responsibility is allocated to such other person by
this Agreement or pursuant to a procedure established in this Agreement or
otherwise. In performing its duties under this Agreement, Custodian shall
exercise the same care and diligence that it would devote to its own property
and shall be liable only for losses arising from its negligence or willful
misconduct.

     Section 8. Indemnification of Custodian.

     The Purchaser agrees to indemnify and hold harmless the Custodian and
its directors, officers, employees, agents and nominees from all taxes (except
taxes on the net income of the Custodian, its agents and its nominees),
charges, expenses, assessments, claims and liabilities (including reasonable
legal fees and expenses) incurred by any of them in connection with the
performance of this Agreement, except such as may arise from any negligent
action, negligent failure to act or willful misconduct on the part of the
indemnified entity.

     Section 9. Compensation of Custodian.

     Throughout the Term of this Agreement, as set forth in Section 14 below,
the Custodian shall perform its duties hereunder without compensation.
Thereafter, the Custodian shall be entitled to reimbursement of expenses
incurred in connection with any necessary transfer following notice of
termination or removal under Sections 11, 12 or 14.

     Section 10. Examination of Custodial Files.

     Upon reasonable prior notice to the Custodian, the Purchaser and its
agents, accounts, attorneys and auditors will be permitted during normal
business hours to examine the records relating to Additional Pledged
Collateral in the possession of or under the control of the Custodian relating
to any or all of the Mortgage Loans.

     Section 11. Removal of Custodian.

     Upon at least 45 days' prior written notice to the Custodian, and only
for cause, the Purchaser may remove and discharge the Custodian from the
performance of its duties under this Agreement. Having given notice of such
removal, the Purchaser promptly shall appoint a successor Custodian to act on
behalf of the Purchaser by written instrument, one original counterpart of
which instrument shall be delivered to the Custodian. Any termination by the
Purchaser shall be accompanied or followed promptly by proper instructions in
writing setting forth the names of the persons to whom the Custodian shall
deliver the Additional Collateral. The Custodian will deliver promptly the
Additional Collateral to the persons so specified, after deducting therefrom
any amounts which the Custodian is owed for services or reimbursement of
expenses hereunder. The Purchaser shall be responsible for the fees of the
successor Custodian.

     Section 12. Termination by Custodian.

     The Custodian may terminate its obligations under this Agreement upon at
least 45 days' prior written notice to the Purchaser. In the event of such
termination, the Purchaser shall appoint a successor Custodian. The payment of
such successor Custodian's fees and expenses shall be solely the
responsibility of the Company or any successor to the Company as servicer
pursuant to the Loan Sale Agreement. If notice of termination is given by the
Custodian, the Purchaser shall, within 30 days following the giving of such
notice, deliver to the Custodian proper instructions in writing specifying the
names of the persons to whom the Custodian shall deliver the Additional
Pledged Collateral held by it. The Custodian will deliver promptly the
Additional Pledged Collateral to the persons so specified, after deducting
therefrom any amounts which the Custodian is owed for services or
reimbursement of expenses hereunder.

     If within 30 days following the giving of a notice of termination by the
Custodian, the Custodian does not receive from the Purchaser proper
instructions in writing specifying the names of the persons to whom the
Custodian shall deliver the assets of the Purchaser held by it, the Custodian,
at its election, may seek court action with respect to the appointment of a
successor custodian.

     Section 13. Survival.

     The obligations of the parties hereto regarding the use of reasonable
care, indemnities and payment of fees and expenses shall survive the
termination of this Agreement.

     Section 14. Term of Agreement.

     Unless terminated pursuant to Section 11 or Section 12 hereof, this
Agreement shall terminate upon the earlier of (1) the resignation or removal
of the Custodian, its agent or affiliate as the servicer under the Loan Sale
Agreement, and (2) the final payment or other liquidation (or advance with
respect thereto) of the last Mortgage Loan or the disposition of all property
acquired upon foreclosure or deed in lieu of foreclosure of any Mortgage Loan,
and the final remittance of all funds due the Purchaser under the Loan Sale
Agreement. In such event, all Additional Pledged Collateral shall be released
in accordance with the written instructions of the Purchaser.

     Section 15. Notices.

     Except as otherwise specified herein, each notice or other communication
hereunder shall be in writing and shall be delivered to the intended recipient

privilege or remedy hereunder, and no delay on the part of any person in the
exercise of any power, right, privilege or remedy hereunder, shall operate as

privilege or remedy shall preclude any other or further exercise thereof or of
any other power, right, privilege or remedy.

any such provision to any person or set of circumstances, shall be determined
to be invalid, unlawful, void or unenforceable to any extent, the remainder of
this Agreement, and the application of such provision to persons or
