ITEM 5.  Other Events

     On August  29,  1997,  Norwest  Asset  Securities  Corporation,  a Delaware
corporation (the "Registrant"),  sold Mortgage Pass-Through Certificates, Series
1997-12, Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class
A-8,  Class A-9,  Class A-10,  Class A-11,  Class A-WIO,  Class A-R, Class A-LR,
Class M,  Class  B-1 and  Class  B-2 (the  "Offered  Certificates"),  having  an
aggregate original principal balance of $229,149,700.  The Offered  Certificates
were issued  pursuant to a Pooling and Servicing  Agreement,  dated as of August
29, 1997, among the Registrant, Norwest Bank Minnesota, National Association, as
master  servicer  (the  "Master  Servicer"  or  "Norwest  Bank") and First Union
National  Bank,  as trustee  (the  "Agreement"),  a copy of which is filed as an
exhibit hereto. Mortgage Pass-Through  Certificates,  Series 1997-12, Class A-7,
Class  B-3,  Class B-4 and Class  B-5,  having an  aggregate  initial  principal
balance of  $95,599,279.65  (the "Private  Certificates"  and, together with the
Class A-PO Certificates and Offered Certificates, the "Certificates"), were also
issued pursuant to the Agreement.

     As of the date of initial issuance,  the Offered Certificates  evidenced an
approximate  70.47%  undivided  interest in a trust fund (the  "Trust  Estate"),
consisting principally of a pool of fixed interest rate,  conventional,  monthly
pay,  fully-amortizing,  one-to  four-family  residential  first mortgage loans,
which may  include  loans  secured  by  shares  issued  by  cooperative  housing
corporations.  The  remaining  undivided  interests  in  the  Trust  Estate  are
evidenced by the Class A-PO Certificates and Private Certificates, distributions
on which (other than with respect to the Class A-7 and Class A-PO  Certificates)
are subordinated to distributions on the Offered Certificates.

     Interest  on  the  Offered   Certificates   will  be  distributed  on  each
Distribution  Date (as  defined  in the  Agreement).  Monthly  distributions  in
reduction of the principal balance of the Offered Certificates will be allocated
to the Offered  Certificates  in accordance with the priorities set forth in the
Agreement.  Distributions  of interest and in reduction of principal  balance on
any  Distribution  Date will be made to the  extent  that the Pool  Distribution
Amount is sufficient therefor.

     An  election  will be made to treat the  Trust  Estate  as two  REMICs  for
federal  income tax purposes (the  "Upper-Tier  REMIC" and  "Lower-Tier  REMIC,"
respectively).  The Class A-1,  Class A-2,  Class A-3,  Class A-4, Class A-5 and
Class A-6 Certificates,  Class A-7 Scheduled Accrual  Component,  Class A-7 IO A
Component,  Class A-7 IO B Component, Class A-7 IO C Component, Class A-8, Class
A-9, Class A-10, Class A-11, Class A-PO, Class A-WIO,  Class M, Class B-1, Class
B-2, Class B-3, Class B-4 and Class B-5 Certificates will be treated as "regular
interests" in the Upper-Tier  REMIC and the Class A-R and Class A-LR Certificate
will  be  treated  as the  "residual  interests"  in the  Upper-Tier  REMIC  and
Lower-Tier REMIC, respectively.

NATIONAL  ASSOCIATION,  as Master  Servicer and FIRST UNION  NATIONAL  BANK,  as
Trustee.


                                WITNESSETH THAT:

     In consideration of the mutual agreements herein contained, the Seller, the
Master Servicer and the Trustee agree as follows:

ARTICLE I

DEFINITIONS

Section 1.01.      Definitions.

     Whenever used herein,  the following words and phrases,  unless the context
otherwise requires, shall have the meanings specified in this Article.

     Accepted Master Servicing  Practices:  Accepted Master Servicing  Practices
shall consist of the customary and usual master  servicing  practices of prudent
master servicing  institutions  which service mortgage loans of the same type as
the  Mortgage  Loans  in  the  jurisdictions  in  which  the  related  Mortgaged
Properties are located,  regardless of the date upon which the related  Mortgage
Loans were originated.

     Adjusted Pool Amount:  With respect to any  Distribution  Date, the Cut-Off

ARTICLE II

CONVEYANCE OF MORTGAGE LOANS;
ORIGINAL ISSUANCE OF THE CERTIFICATES

Section 2.01.      Conveyance of Mortgage Loans.

     The Seller,  concurrently  with the  execution  and delivery  hereof,  does
hereby assign to the Trustee, without recourse all the right, title and interest
of the  Seller  in and to (a) the  Trust  Estate,  including  all  interest  and
principal  received by the Seller on or with respect to the Mortgage Loans after
the Cut-Off Date (and including scheduled payments of principal and interest due
after the Cut-Off  Date but received by the Seller on or before the Cut-Off Date
and Unscheduled  Principal Receipts received or applied on the Cut-Off Date, but
not including payments of principal and interest due on the Mortgage Loans on or
before the Cut-Off Date), (b) the Insurance Policies, (c) the obligations of the
Servicers under the Servicing  Agreements with respect to the Mortgage Loans and
(d) proceeds of all the foregoing.

     In connection with such assignment,  the Seller shall, with respect to each
Mortgage Loan,  deliver,  or cause to be delivered,  to the Trustee,  as initial
custodian,  on or before the Closing Date,  an Owner  Mortgage Loan File. If any
Mortgage or an assignment  of a Mortgage to the Trustee or any prior  assignment
is in the  process of being  recorded  on the  Closing  Date,  the Seller  shall
deliver a copy thereof,  certified by Norwest Mortgage or the applicable Norwest
Mortgage  Correspondent  to be a true and complete copy of the document sent for
recording, and the Seller shall use its best efforts to cause each such original
recorded  document or  certified  copy  thereof to be  delivered  to the Trustee
promptly  following  its  recordation,  but in no event  later than one (1) year
following the Closing  Date.  The Seller shall also cause to be delivered to the
Trustee any other  original  mortgage  loan document to be included in the Owner
Mortgage  Loan File if a copy thereof has been  delivered.  The Seller shall pay
from its own funds, without any right of reimbursement  therefor,  the amount of
any costs,  liabilities  and expenses  incurred by the Trust Estate by reason of
the failure of the Seller to cause to be delivered to the Trustee within one (1)
year  following  the  Closing  Date any  original  Mortgage or  assignment  of a
Mortgage not delivered to the Trustee on the Closing Date.

     In lieu of recording an  assignment  of any Mortgage the Seller may, to the
extent set forth in any Servicing Agreement, deliver or cause to be delivered to
the Trustee the  assignment  of the Mortgage Loan from the Seller to the Trustee
in a form suitable for  recordation,  together with an Opinion of Counsel to the
effect that recording is not required to protect the Trustee's right,  title and
interest  in and to the  related  Mortgage  Loan  or,  in  case a  court  should
recharacterize the sale of the Mortgage Loans as a financing, to perfect a first
priority security interest in favor of the Trustee in the related Mortgage Loan.
In the event that the Master Servicer receives notice that recording is required
to  protect  the right,  title and  interest  of the  Trustee in and to any such
Mortgage Loan for which recordation of an



<PAGE>



assignment has not previously been required,  the Master Servicer shall promptly
notify the Trustee  and the Trustee  shall  within five  Business  Days (or such
other reasonable  period of time mutually agreed upon by the Master Servicer and
the Trustee) of its receipt of such notice  deliver each  previously  unrecorded
assignment to the related Servicer for recordation.

Section 2.02.      Acceptance by Trustee.

     The Trustee acknowledges receipt of the Mortgage Notes, the Mortgages,  the
assignments  and other  documents  required to be  delivered on the Closing Date
pursuant  to Section  2.01 above and  declares  that it holds and will hold such
documents and the other documents constituting a part of the Owner Mortgage Loan
Files  delivered to it in trust,  upon the trusts herein set forth,  for the use
and benefit of all present and future  Certificateholders.  The Trustee  agrees,
for the benefit of  Certificateholders,  to review each Owner Mortgage Loan File
within 45 days after  execution of this Agreement in order to ascertain that all
required documents set forth in Section 2.01 have been executed and received and
appear  regular on their face,  and that such  documents  relate to the Mortgage
Loans identified in the Mortgage Loan Schedule,  and in so doing the Trustee may
rely on the purported due execution and  genuineness of any such document and on
the purported genuineness of any signature thereon. If within such 45 day period
the Trustee  finds any document  constituting  a part of an Owner  Mortgage Loan
File not to have been  executed or received or to be  unrelated  to the Mortgage
Loans  identified in the Mortgage Loan Schedule or not to appear  regular on its
face,  the Trustee  shall  promptly (and in no event more than 30 days after the
discovery  of such  defect)  notify the Seller,  which shall have a period of 60
days  after the date of such  notice  within  which to  correct or cure any such
defect.  The Seller hereby  covenants and agrees that, if any material defect is
not so  corrected or cured,  the Seller  will,  not later than 60 days after the
Trustee's  notice to it referred to above  respecting  such  defect,  either (i)
repurchase the related Mortgage Loan or any property acquired in respect thereof
from the  Trust  Estate  at a price  equal to (a) 100% of the  unpaid  principal
balance of such Mortgage Loan plus (b) accrued interest at the Mortgage Interest
Rate through the last day of the month in which such  repurchase  takes place or
(ii) if within two years of the Startup Day, or such other  period  permitted by
the REMIC  Provisions,  substitute  for any Mortgage Loan to which such material
defect relates,  a new mortgage loan (a "Substitute  Mortgage Loan") having such
characteristics  so that the  representations  and  warranties of the Seller set
forth in Section 2.03(b) hereof (other than Section  2.03(b)(i))  would not have
been  incorrect had such  Substitute  Mortgage Loan  originally  been a Mortgage
Loan. In no event shall any  Substitute  Mortgage Loan have an unpaid  principal
balance,  as of the date of substitution,  greater than the Scheduled  Principal
Balance  (reduced by the  scheduled  payment of principal due on the Due Date in
the month of substitution) of the Mortgage Loan for which it is substituted.  In
addition,  such Substitute  Mortgage Loan shall have a Loan-to-Value  Ratio less
than or equal to and a Mortgage Interest Rate equal to that of the Mortgage Loan
for which it is substituted.

     In the case of a repurchased Mortgage Loan or property,  the purchase price
shall be deposited by the Seller in the  Certificate  Account  maintained by the
Master Servicer  pursuant to Section 3.01. In the case of a Substitute  Mortgage
Loan,  the Owner  Mortgage Loan File relating  thereto shall be delivered to the
Trustee and the Substitution Principal



<PAGE>



Amount,  together with (i) interest on such Substitution Principal Amount at the
applicable Net Mortgage Interest Rate to the following Due Date of such Mortgage
Loan which is being  substituted  for and (ii) an amount equal to the  aggregate
amount of unreimbursed  Periodic Advances in respect of interest previously made
by the Servicer,  Master Servicer or Trustee with respect to such Mortgage Loan,
shall be  deposited  in the  Certificate  Account.  The  Monthly  Payment on the
Substitute Mortgage Loan for the Due Date in the month of substitution shall not
be part of the Trust Estate. Upon receipt by the Trustee of written notification
of any such  deposit  signed  by an  officer  of the  Seller,  or the new  Owner
Mortgage  Loan File, as the case may be, the Trustee shall release to the Seller
the  related  Owner  Mortgage  Loan  File and shall  execute  and  deliver  such
instrument of transfer or assignment, in each case without recourse, as shall be
necessary  to  vest  in the  Seller  legal  and  beneficial  ownership  of  such
substituted  or  repurchased  Mortgage Loan or property.  It is  understood  and
agreed that the  obligation  of the Seller to substitute a new Mortgage Loan for
or repurchase  any Mortgage Loan or property as to which such a material  defect
in a constituent  document  exists shall  constitute the sole remedy  respecting
such defect available to the  Certificateholders or the Trustee on behalf of the
Certificateholders.  The failure of the Trustee to give any notice  contemplated
herein within  forty-five  (45) days after the execution of this Agreement shall
not affect or relieve the Seller's  obligation to  repurchase  any Mortgage Loan
pursuant to this Section 2.02.

     The Trustee may,  concurrently with the execution and delivery hereof or at
any time thereafter,  enter into a Custodial Agreement substantially in the form
of Exhibit E hereto  pursuant to which the Trustee  appoints a Custodian to hold
the Mortgage Notes, the Mortgages,  the assignments and other documents  related
to the  Mortgage  Loans  received by the Trustee in trust for the benefit of all
present and future  Certificateholders,  which may provide,  among other things,
that the Custodian shall conduct the review of such documents required under the
first paragraph of this Section 2.02.

Section 2.03.      Representations  and  Warranties  of the Master  Servicer
and the Seller.

     (a) The Master Servicer  hereby  represents and warrants to the Trustee for
the benefit of  Certificateholders  that,  as of the date of  execution  of this
Agreement:

          (i)  The  Master  Servicer  is a  national  banking  association  duly
     chartered  and  validly  existing  in good  standing  under the laws of the
     United States;

          (ii) The  execution  and  delivery  of this  Agreement  by the  Master
     Servicer  and  its  performance  and  compliance  with  the  terms  of this
     Agreement  will not  violate  the Master  Servicer's  corporate  charter or
     by-laws or constitute a default (or an event which, with notice or lapse of
     time, or both,  would  constitute a default) under, or result in the breach
     of, any  material  contract,  agreement  or other  instrument  to which the
     Master  Servicer is a party or which may be  applicable  to the Servicer or
     any of its assets;



<PAGE>



          (iii)  This  Agreement,  assuming  due  authorization,  execution  and
     delivery  by the Trustee and the  Seller,  constitutes  a valid,  legal and
     binding  obligation  of the  Master  Servicer,  enforceable  against  it in
     accordance  with  the  terms  hereof  subject  to  applicable   bankruptcy,
     insolvency,  reorganization,   moratorium  and  other  laws  affecting  the
     enforcement  of creditors'  rights  generally and to general  principles of
     equity,   regardless  of  whether  such  enforcement  is  considered  in  a
     proceeding in equity or at law;

          (iv) The Master  Servicer is not in default  with respect to any order
     or decree of any court or any order,  regulation  or demand of any federal,
     state,   municipal  or  governmental   agency,  which  default  might  have
     consequences  that would  materially  and  adversely  affect the  condition
     (financial or other) or operations of the Master Servicer or its properties
     or might have consequences that would affect its performance hereunder; and

          (v) No litigation is pending or, to the best of the Master  Servicer's
     knowledge,  threatened against the Master Servicer which would prohibit its
     entering  into this  Agreement or  performing  its  obligations  under this
     Agreement.

     It is understood  and agreed that the  representations  and  warranties set
forth in this Section  2.03(a) shall survive  delivery of the  respective  Owner
Mortgage Loan Files to the Trustee or the Custodian.

     (b) The Seller  hereby  represents  and  warrants  to the  Trustee  for the
benefit  of  Certificateholders  that,  as of the  date  of  execution  of  this

     any nature and has full right and authority to sell and assign the same;

          (iii) The Mortgage is a valid,  subsisting and enforceable  first lien
     on the property therein  described,  and the Mortgaged Property is free and
     clear of all  encumbrances and liens having priority over the first lien of
     the Mortgage except for liens for real estate taxes and special assessments
     not yet due and payable and liens or interests arising under or as a result
     of any federal,  state or local law,  regulation  or ordinance  relating to
     hazardous  wastes or hazardous  substances,  and, if the related  Mortgaged
     Property is a condominium  unit, any lien for common  charges  permitted by
     statute or  homeowners  association  fees;  and if the  Mortgaged  Property
     consists  of  shares of a  cooperative  housing  corporation,  any lien for
     amounts due to the cooperative  housing  corporation for unpaid assessments

     Trustee or to the Custodian with, any Mortgage  establishes in the Seller a
     valid and subsisting first lien on the property  described  therein and the

     remains  unpaid;  and the Seller has not  advanced  funds,  or received any

     the Mortgage  Loan or the use for which the premises  were  intended and to
     the best of the  Seller's  knowledge,  there is no  proceeding  pending  or
     threatened for the total or partial condemnation of the Mortgaged Property;

          (vii) The Mortgaged  Property is free and clear of all  mechanics' and
     materialmen's liens or liens in the nature thereof; provided, however, that

<PAGE>



     by Mortgaged Property located in Iowa, as to which an opinion of counsel of
     the type  customarily  rendered in such State in lieu of title insurance is
     instead  received)  is  covered  by  an  American  Land  Title  Association
     mortgagee  title  insurance  policy or other  generally  acceptable form of
     policy or insurance  acceptable to FNMA or FHLMC, issued by a title insurer
     acceptable to FNMA or FHLMC  insuring the  originator,  its  successors and
     assigns,  as to the first  priority  lien of the  Mortgage in the  original
     principal  amount of the Mortgage  Loan and subject only to (A) the lien of
     current real property taxes and  assessments  not yet due and payable,  (B)
     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
     Mortgaged Property is located or specifically  referred to in the appraisal
     performed in connection with the origination of the related  Mortgage Loan,
     (C) liens created pursuant to any federal,  state or local law,  regulation
     or  ordinance  affording  liens  for the  costs of  clean-up  of  hazardous
     substances  or  hazardous  wastes  or for  other  environmental  protection
     purposes and (D) 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;  the Seller is the sole insured of such mortgagee title insurance
     policy,  the  assignment  to the Trustee of the  Seller's  interest in such
     mortgagee  title  insurance  policy  does not  require  any  consent  of or
     notification  to the  insurer  which has not been  obtained  or made,  such
     mortgagee title insurance policy is in full force and effect and will be in
     full force and effect and inure to the  benefit of the  Trustee,  no claims
     have been made under such mortgagee  title insurance  policy,  and no prior
     holder of the related Mortgage,  including the Seller,  has done, by act or
     omission,  anything which would impair the coverage of such mortgagee title
     insurance policy;

          (xvi) The Mortgaged Property securing each Mortgage Loan is insured by
     an  insurer  acceptable  to FNMA or  FHLMC  against  loss by fire  and such
     hazards as are covered under a standard extended coverage  endorsement,  in
     an amount which is not less than the lesser of 100% of the insurable  value
     of the  Mortgaged  Property and the  outstanding  principal  balance of the
     Mortgage Loan,  but in no event less than the minimum  amount  necessary to
     fully compensate for any damage or loss on a replacement cost basis; if the
     Mortgaged Property is a condominium unit, it is included under the coverage
     afforded by a blanket  policy for the project;  if upon  origination of the
     Mortgage Loan, the  improvements on the Mortgaged  Property were in an area
     identified  in the Federal  Register by the  Federal  Emergency  Management
     Agency as having special flood hazards,  a flood  insurance  policy meeting
     the  requirements  of  the  current  guidelines  of the  Federal  Insurance
     Administration is in effect with a generally  acceptable insurance carrier,
     in an  amount  representing  coverage  not less  than the  least of (A) the
     outstanding  principal balance of the Mortgage Loan, (B) the full insurable
     value of the  Mortgaged  Property  and (C) the maximum  amount of insurance
     which was available  under the Flood  Disaster  Protection Act of 1973; and
     each  Mortgage  obligates  the  Mortgagor  thereunder  to maintain all such
     insurance at the Mortgagor's cost and expense;



<PAGE>



          (xvii) To the best of the  Seller's  knowledge,  there is no  default,
     breach,  violation or event of acceleration  existing under the Mortgage or
     the related  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;  the
     Seller  has  not  waived  any  default,   breach,  violation  or  event  of
     acceleration; and no foreclosure action is currently threatened or has been
     commenced with respect to the Mortgage Loan;

          (xviii)  No  Mortgage  Note or  Mortgage  is  subject  to any right of
     rescission,  set-off,  counterclaim  or defense,  including  the defense of
     usury,  nor will the  operation of any of the terms of the Mortgage Note or
     Mortgage, or the exercise of any right thereunder, render the Mortgage Note
     or Mortgage unenforceable,  in whole or in part, or subject it to any right
     of rescission,  set-off,  counterclaim or defense, including the defense of
     usury,  and no such right of rescission,  set-off,  counterclaim or defense
     has been asserted with respect thereto;

          (xix) Each Mortgage Note is payable in monthly payments,  resulting in
     complete amortization of the Mortgage Loan over a term of not more than 360
     months;

          (xx) Each 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,
     including  realization by judicial  foreclosure  (subject to any limitation
     arising  from any  bankruptcy,  insolvency  or other law for the  relief of
     debtors),  and there is no  homestead or other  exemption  available to the
     Mortgagor which would interfere with such right of foreclosure;

          (xxi) To the best of the Seller's knowledge,  no Mortgagor is a debtor
     in any state or federal bankruptcy or insolvency proceeding;

          (xxii) Each  Mortgaged  Property  is located in the United  States and
     consists of a one- to four-unit residential  property,  which may include a
     detached  home,  townhouse,  condominium  unit or a unit in a planned  unit
     development  or, in the case of  Mortgage  Loans  secured by Co-op  Shares,
     leases or occupancy agreements;

          (xxiii) The Mortgage Loan is a "qualified mortgage" within the meaning
     of Section 860G of the Code;

          (xxiv) With respect to each Mortgage  where a lost note  affidavit has
     been  delivered to the Trustee in place of the related  Mortgage  Note, the
     related Mortgage Note is no longer in existence;

          (xxv) In the  event  that the  Mortgagor  is an inter  vivos  "living"
     trust,  (i) such trust is in  compliance  with FNMA or FHLMC  standards for
     inter vivos trusts and (ii) holding title to the Mortgaged Property in such
     trust will not  diminish  any rights as a creditor  including  the right to
     full title to the Mortgaged  Property in the event foreclosure  proceedings
     are initiated; and



<PAGE>



          (xxvi) If the  Mortgage  Loan is  secured by a  long-term  residential
     lease,  (1) the lessor  under the lease holds a fee simple  interest in the
     land;  (2) the terms of such lease  expressly  permit the mortgaging of the
     leasehold estate,  the assignment of the lease without the lessor's consent
     and the  acquisition  by the  holder of the  Mortgage  of the rights of the
     lessee upon foreclosure or assignment in lieu of foreclosure or provide the
     holder of the Mortgage  with  substantially  similar  protections;  (3) the
     terms of such  lease do not (a)  allow  the  termination  thereof  upon the
     lessee's  default  without  the holder of the  Mortgage  being  entitled to
     receive written notice of, and opportunity to cure, such default, (b) allow
     the  termination of the lease in the event of damage or destruction as long
     as the  Mortgage is in  existence,  (c) prohibit the holder of the Mortgage
     from being  insured (or receiving  proceeds of insurance)  under the hazard
     insurance  policy or  policies  relating to the  Mortgaged  Property or (d)
     permit any increase in rent other than pre-established  increases set forth
     in the  lease;  (4) the  original  term of such  lease is not less  than 15
     years;  (5) the term of such lease  does not  terminate  earlier  than five
     years after the maturity date of the Mortgage  Note;  and (6) the Mortgaged
     Property is located in a jurisdiction in which the use of leasehold estates
     in  transferring  ownership in residential  properties is a widely accepted
     practice.

     Notwithstanding the foregoing, no representations or warranties are made by
the Seller as to the  environmental  condition of any  Mortgaged  Property;  the
absence,  presence or effect of hazardous wastes or hazardous  substances on any
Mortgaged  Property;  any  casualty  resulting  from the  presence  or effect of
hazardous  wastes  or  hazardous  substances  on,  near or  emanating  from  any
Mortgaged  Property;  the  impact  on  Certificateholders  of any  environmental
condition  or  presence  of any  hazardous  substance  on or near any  Mortgaged
Property;  or the  compliance of any Mortgaged  Property with any  environmental
laws, nor is any agent,  person or entity  otherwise  affiliated with the Seller
authorized  or able to make any such  representation,  warranty or assumption of
liability relative to any Mortgaged Property. In addition, no representations or
warranties are made by the Seller with respect to the absence or effect of fraud
in the origination of any Mortgage Loan.

     It is understood  and agreed that the  representations  and  warranties set
forth in this Section  2.03(b) shall survive  delivery of the  respective  Owner
Mortgage Loan Files to the Trustee and shall inure to the benefit of the Trustee
notwithstanding any restrictive or qualified endorsement or assignment.

     (c) Upon discovery by either the Seller,  the Master Servicer,  the Trustee
or the  Custodian  that  any of  the  representations  and  warranties  made  in
subsection (b) above is not accurate (referred to herein as a "breach") and that
such  breach   materially   and   adversely   affects  the   interests   of  the
Certificateholders  in the related  Mortgage  Loan, the party  discovering  such
breach shall give prompt  written  notice to the other  parties  (any  Custodian
being so obligated under a Custodial  Agreement).  Within 60 days of the earlier
of its  discovery or its receipt of notice of any such breach,  the Seller shall
cure such breach in all  material  respects or shall either (i)  repurchase  the
Mortgage Loan or any property  acquired in respect thereof from the Trust Estate
at a price equal to (A) 100% of the unpaid  principal  balance of such  Mortgage
Loan plus (B) accrued interest at the Net Mortgage Interest Rate for



<PAGE>



such  Mortgage  Loan through the last day of the month in which such  repurchase
took place or (ii) if within two years of the Startup  Day, or such other period
permitted by the REMIC  Provisions,  substitute  for such  Mortgage  Loan in the
manner described in Section 2.02. The purchase price of any repurchase described
in this paragraph and the Substitution  Principal  Amount,  if any, plus accrued
interest  thereon and the other amounts  referred to in Section  2.02,  shall be
deposited  in the  Certificate  Account.  It is  understood  and agreed that the
obligation of the Seller to  repurchase  or substitute  for any Mortgage Loan or
property  as to  which  such a  breach  has  occurred  and is  continuing  shall
constitute   the   sole   remedy    respecting   such   breach    available   to

ARTICLE III

ADMINISTRATION OF THE TRUST ESTATE:  SERVICING
OF THE MORTGAGE LOANS

Section 3.01.      Certificate Account.

     (a) The Master Servicer shall establish and maintain a Certificate  Account
for the deposit of funds  received by the Master  Servicer  with  respect to the
Mortgage  Loans  serviced by each  Servicer  pursuant  to each of the  Servicing
Agreements.  Such account shall be maintained as an Eligible Account. The Master
Servicer  shall give notice to each  Servicer  and the Seller of the location of
the Certificate Account and of any change in the location thereof.

     (b) The Master Servicer shall deposit into the  Certificate  Account on the
day of receipt thereof all amounts received by it from any Servicer  pursuant to
any of the  Servicing  Agreements,  and shall,  in  addition,  deposit  into the
Certificate  Account the following amounts,  in the case of amounts specified in
clause  (i),  not later than the  Distribution  Date on which such  amounts  are
required to be distributed to Certificateholders and, in the case of the amounts
specified in clause (ii), not later than the Business Day next following the day
of receipt and posting by the Master Servicer:

          (i) Periodic  Advances  pursuant to Section 3.03(a) made by the Master
     Servicer or the Trustee, if any; and

          (ii) in the  case of any  Mortgage  Loan  that is  repurchased  by the
     Seller  pursuant to Section 2.02 or 2.03 or that is auctioned by the Master
     Servicer  pursuant  to Section  3.08 or  purchased  by the Master  Servicer
     pursuant to Section  3.08 or 9.01,  the purchase  price  therefor or, where
     applicable,  any Substitution  Principal Amount and any amounts received in
     respect of the interest portion of unreimbursed Periodic Advances.

     (c) The Master Servicer shall cause the funds in the Certificate Account to
be invested in Eligible  Investments.  No such Eligible Investments will be sold
or  disposed  of at a gain prior to  maturity  unless the  Master  Servicer  has
received an Opinion of Counsel or other  evidence  satisfactory  to it that such
sale or disposition  will not cause the Trust Estate to be subject to Prohibited
Transactions Tax,  otherwise subject the Trust Estate to tax, or cause either of
the Upper-Tier REMIC or the Lower-Tier REMIC to fail to qualify as a REMIC while
any  Certificates  are  outstanding.  Any amounts  deposited in the  Certificate
Account prior to the Distribution  Date shall be invested for the account of the
Master   Servicer  and  any  investment   income  thereon  shall  be  additional
compensation to the Master Servicer for services  rendered under this Agreement.
The amount of any losses  incurred in respect of any such  investments  shall be
deposited in the Certificate Account by the Master Servicer out of its own funds
immediately as realized.

Section 3.02.      Permitted Withdrawals from the Certificate Account.

     (a) The Master Servicer may, from time to time, make  withdrawals  from the
Certificate Account for the following purposes (limited, in the case of Servicer
reimbursements, to cases where funds in the respective Custodial P&I Account are
not sufficient therefor):

          (i) to reimburse the Master Servicer,  the Trustee or any Servicer for

     2.03, 3.08 or 9.01) respecting which any such Periodic Advance was made;

          (ii) to reimburse any Servicer, the Master Servicer or the Trustee for

     Agreement,  respectively,  in good faith in connection with the restoration
     of damaged property or for foreclosure expenses;

          (iv) from any  Mortgagor  payment  on  account  of  interest  or other
     recovery (including Net REO Proceeds) with respect to a particular Mortgage
     Loan, to pay the Master Servicing Fee with respect to such Mortgage Loan to
     the Master Servicer;

          (v) to reimburse the Master Servicer, any Servicer or the Trustee (or,
     in certain cases, the Seller) for expenses  incurred by it (including taxes
     paid on behalf of the Trust Estate) and  recoverable by or  reimbursable to
     it pursuant to Section  3.03(c),  3.03(d) or 6.03 or the second sentence of
     Section  8.14(a)  or  pursuant  to  such  Servicer's  Servicing  Agreement,
     provided such expenses are "unanticipated"  within the meaning of the REMIC
     Provisions;

          (vi) to pay to the  Seller or other  purchaser  with  respect  to each
     Mortgage  Loan or  property  acquired  in  respect  thereof  that  has been
     repurchased  or  replaced  pursuant  to Section  2.02 or 2.03 or  auctioned
     pursuant to Section 3.08 or to pay to the Master  Servicer  with respect to
     each  Mortgage Loan or property  acquired in respect  thereof that has been

          (viii)  to  pay to the  Master  Servicer  any  interest  earned  on or
     investment income with respect to funds in the Certificate Account;

          (ix)  to  pay to  the  Master  Servicer  or  any  Servicer  out of Net
     Liquidation  Proceeds allocable to interest the amount of any unpaid Master
     Servicing  Fee or Servicing  Fee (as adjusted  pursuant to such  Servicer's
     Servicing  Agreement) and any unpaid  assumption fees, late payment charges
     or other Mortgagor charges on the related Mortgage Loan;

          (x) to withdraw from the Certificate  Account any amount  deposited in
     the Certificate Account that was not required to be deposited therein; and

          (xi) to clear  and  terminate  the  Certificate  Account  pursuant  to
     Section 9.01.

     (b) The Master Servicer shall keep and maintain separate  accounting,  on a
Mortgage Loan by Mortgage Loan basis,  for the purpose of justifying any payment
to and withdrawal from the Certificate Account.

Section 3.03.      Advances by Master Servicer and Trustee.

     (a) In the  event an Other  Servicer  fails to make any  required  Periodic
Advances of principal and interest on a Mortgage Loan as required by the related
Other Servicing  Agreement prior to the Distribution Date occurring in the month
during  which such  Periodic  Advance is due,  the  Master  Servicer  shall make
Periodic  Advances to the extent provided hereby.  In the event Norwest Mortgage
fails to make any  required  Periodic  Advances of  principal  and interest on a
Mortgage  Loan as  required  by the  Norwest  Servicing  Agreement  prior to the
Distribution  Date occurring in the month during which such Periodic  Advance is
due,  the  Trustee  shall,  to the extent  required by Section  8.15,  make such
Periodic  Advance to the extent provided  hereby,  provided that the Trustee has
previously  received the  certificate  of the Master  Servicer  described in the
following  sentence.  The Master  Servicer  shall  certify to the  Trustee  with
respect  to any such  Distribution  Date (i) the  amount  of  Periodic  Advances
required of Norwest  Mortgage or such Other  Servicer,  as the case may be, (ii)
the  amount  actually  advanced,  (iii) the  amount  that the  Trustee or Master
Servicer is required to advance  hereunder and (iv) whether the Master  Servicer
has  determined  that it reasonably  believes  that such  Periodic  Advance is a
Nonrecoverable Advance. Amounts advanced by the Trustee or Master Servicer shall
be  deposited  in the  Certificate  Account on the  related  Distribution  Date.
Notwithstanding the foregoing,  neither the Master Servicer nor the Trustee will
be obligated  to make a Periodic  Advance  that it  reasonably  believes to be a
Nonrecoverable  Advance. The Trustee may conclusively rely for any determination
to be made by it hereunder upon the  determination of the Master Servicer as set
forth in its certificate.

     (b) To the extent an Other  Servicer fails to make an advance on account of
the taxes or  insurance  premiums  with  respect  to a  Mortgage  Loan  required
pursuant to the related Other Servicing Agreement, the Master Servicer shall, if
the Master Servicer knows of



<PAGE>



such  failure  of the  Servicer,  advance  such funds and take such steps as are
necessary  to pay such  taxes  or  insurance  premiums.  To the  extent  Norwest
Mortgage fails to make an advance on account of the taxes or insurance  premiums
with  respect to a Mortgage  Loan  required  pursuant to the  Norwest  Servicing
Agreement,  the Master  Servicer  shall,  if the Master  Servicer  knows of such
failure of  Norwest  Mortgage,  certify to the  Trustee  that such  failure  has
occurred.  Upon receipt of such  certification,  the Trustee  shall advance such
funds  and take  such  steps as are  necessary  to pay such  taxes or  insurance
premiums.

     (c) The  Master  Servicer  and the  Trustee  shall each be  entitled  to be
reimbursed  from the  Certificate  Account for any  Periodic  Advance made by it
under Section 3.03(a) to the extent described in Section 3.02(a)(i) and (a)(ii).
The Master Servicer and the Trustee shall be entitled to be reimbursed  pursuant
to Section  3.02(a)(v)  for any advance by it pursuant to Section  3.03(b).  The
Master  Servicer  shall  diligently  pursue  restoration  of such  amount to the
Certificate Account from the related Servicer. The Master Servicer shall, to the
extent it has not already  done so, upon the  request of the  Trustee,  withdraw
from the  Certificate  Account and remit to the Trustee any amounts to which the
Trustee is entitled as reimbursement  pursuant to Section 3.02 (a)(i),  (ii) and
(v).

     (d) Except as  provided  in Section  3.03(a)  and (b),  neither  the Master
Servicer  nor the Trustee  shall be required to pay or advance any amount  which
any Servicer was required, but failed, to deposit in the Certificate Account.

Section 3.04.      Trustee to Cooperate;
Release of Owner Mortgage Loan Files.

     Upon the  receipt  by the  Master  Servicer  of a Request  for  Release  in
connection  with the deposit by a Servicer into the  Certificate  Account of the
proceeds from a Liquidated  Loan or of a Prepayment in Full, the Master Servicer
shall  confirm to the Trustee  that all  amounts  required to be remitted to the
Certificate  Account  in  connection  with  such  Mortgage  Loan  have  been  so
deposited,  and shall  deliver  such  Request  for Release to the  Trustee.  The
Trustee  shall,  within five  Business Days of its receipt of such a Request for
Release,  release the related Owner Mortgage Loan File to the Master Servicer or
such  Servicer,  as requested by the Master  Servicer.  No expenses  incurred in
connection with any instrument of satisfaction or deed of reconveyance  shall be
chargeable to the Certificate Account.

     From time to time and as  appropriate  for the servicing or  foreclosure of
any Mortgage Loan,  including but not limited to, collection under any insurance
policies, or to effect a partial release of any Mortgaged Property from the lien
of the Mortgage,  the Servicer of such Mortgage Loan shall deliver to the Master
Servicer a Request for Release.  Upon the Master Servicer's  receipt of any such
Request for Release,  the Master Servicer shall promptly forward such request to
the Trustee and the  Trustee  shall,  within  five  Business  Days,  release the
related Owner  Mortgage Loan File to the Master  Servicer or such  Servicer,  as
requested by the Master  Servicer.  Any such Request for Release shall  obligate
the Master  Servicer  or such  Servicer,  as the case may be, to return each and
every  document  previously  requested  from the Owner Mortgage Loan File to the
Trustee by the twenty-first day following the release thereof,



<PAGE>



unless (i) the Mortgage Loan has been  liquidated and the  Liquidation  Proceeds
relating to the Mortgage Loan have been deposited in the Certificate  Account or
(ii) the Owner  Mortgage  Loan File or such  document  has been  delivered to an
attorney,  or to a public  trustee or other public  official as required by law,
for purposes of initiating or pursuing legal action or other proceedings for the
foreclosure of the Mortgaged Property either judicially or  non-judicially,  and
the Master  Servicer has  delivered to the Trustee a  certificate  of the Master
Servicer or such Servicer certifying as to the name and address of the Person to
which such Owner  Mortgage  Loan File or such  document  was  delivered  and the
purpose or purposes of such delivery.  Upon receipt of an Officer's  Certificate
of the Master  Servicer or such  Servicer  stating that such  Mortgage  Loan was
liquidated  and that all amounts  received or to be received in connection  with
such liquidation which are required to be deposited into the Certificate Account
have been so  deposited,  or that such  Mortgage Loan has become an REO Mortgage
Loan,  the Request  for  Release  shall be released by the Trustee to the Master
Servicer or such Servicer, as appropriate.

     Upon written  certification  of the Master Servicer or the Servicer of such
Mortgage Loan,  the Trustee shall execute and deliver to the Master  Servicer or
such Servicer, as directed by the Master Servicer, court pleadings, requests for
trustee's sale or other documents necessary to the foreclosure or trustee's sale
in respect of a  Mortgaged  Property  or to any legal  action  brought to obtain
judgment  against any  Mortgagor on the Mortgage Note or Mortgage or to obtain a
deficiency judgment,  or to enforce any other remedies or rights provided by the
Mortgage Note or Mortgage or otherwise  available at law or in equity. Each such
certification  shall  include a request  that such  pleadings  or  documents  be
executed  by the Trustee and a  statement  as to the reason  such  documents  or
pleadings  are  required  and that the  execution  and  delivery  thereof by the
Trustee will not invalidate or otherwise affect the lien of the Mortgage, except
for the termination of such a lien upon completion of the foreclosure proceeding
or trustee's sale.

Section 3.05.      Reports to the Trustee; Annual Compliance Statements.

     (a) Not  later  than 15 days  after  each  Distribution  Date,  the  Master
Servicer  shall  deliver to the Trustee a statement  setting forth the status of
the Certificate  Account as of the close of business on such  Distribution  Date
stating that all distributions  required to be made by the Master Servicer under
this  Agreement  have been made (or, if any required  distribution  has not been
made by the Master  Servicer,  specifying  the nature  and status  thereof)  and
showing,  for the period  covered by such  statement,  the  aggregate  amount of
deposits into and withdrawals from such account for each category of deposit and
withdrawal  specified in Sections  3.01 and 3.02.  Such  statement may be in the
form of the then  current  FNMA  monthly  accounting  report for its  Guaranteed
Mortgage  Pass-Through Program with appropriate additions and changes, and shall
also include  information as to the aggregate unpaid principal balance of all of
the  Mortgage  Loans  as of the  close  of  business  as of the  last day of the
calendar month  immediately  preceding such  Distribution  Date.  Copies of such
statement shall be provided by the Trustee to any Certificateholder upon written
request, provided such statement is delivered, or caused to be delivered, by the
Master Servicer to the Trustee.



<PAGE>



     (b) The Master  Servicer shall deliver to the Trustee on or before April 30
of each  year,  a  certificate  signed by an  officer  of the  Master  Servicer,
certifying  that (i) such  officer has  reviewed  the  activities  of the Master
Servicer  during  the  preceding  calendar  year  or  portion  thereof  and  its
performance  under  this  agreement  and  (ii) to the  best  of  such  officer's
knowledge, based on such review, the Master Servicer has performed and fulfilled
its  duties,  responsibilities  and  obligations  under  this  agreement  in all
material  respects  throughout such year, or, if there has been a default in the
fulfillment of any such duties, responsibilities or obligations, specifying each
such default known to such officer and the nature and status thereof, and, (iii)
(A)  the  Master   Servicer  has  received  from  each  Servicer  any  financial
statements, officer's certificates, accountant's statements or other information
required to be provided to the Master Servicer pursuant to the related Servicing
Agreement and (B) to the best of such officer's knowledge,  based on a review of
the information provided to the Master Servicer by each Servicer as described in
(iii)(A)   above,   each  Servicer  has  performed  and  fulfilled  its  duties,
responsibilities  and obligations under the related  Servicing  Agreement in all
material  respects  throughout such year, or, if there has been a default in the
fulfillment of any such duties, responsibilities or obligations, specifying each
such default known to such officer and the nature and status thereof.  Copies of
such   officers'   certificate   shall  be   provided  by  the  Trustee  to  any
Certificateholder  upon written request  provided such certificate is delivered,
or caused to be delivered, by the Master Servicer to the Trustee.

Section 3.06.      Title, Management and Disposition of Any REO Mortgage Loan.

     The  Master   Servicer   shall  ensure  that  each  REO  Mortgage  Loan  is
administered  by the  related  Servicer  at all  times so that it  qualifies  as
"foreclosure  property" under the REMIC Provisions and that it does not earn any
"net income from  foreclosure  property" which is subject to tax under the REMIC
Provisions.  In the  event  that a  Servicer  is unable  to  dispose  of any REO
Mortgage Loan within the period  mandated by each of the  Servicing  Agreements,
the Master Servicer shall monitor such Servicer to verify that such REO Mortgage
Loan is auctioned to the highest  bidder within the period so specified.  In the
event of any such sale of REO Mortgage Loan,  the Trustee shall,  at the written
request of the Master Servicer and upon being supported with  appropriate  forms
therefor, within five Business Days of the deposit by the Master Servicer of the
proceeds of such sale or auction into the Certificate Account,  release or cause
to be released to the entity identified by the Master Servicer the related Owner
Mortgage Loan File and Servicer Mortgage Loan File and shall execute and deliver
such instruments of transfer or assignment,  in each case without  recourse,  as
shall be  necessary to vest in the auction  purchaser  title to the REO Mortgage
Loan and the Trustee  shall have no further  responsibility  with regard to such
Owner  Mortgage Loan File or Servicer  Mortgage Loan File.  Neither the Trustee,
the Master  Servicer  nor any  Servicer,  acting on behalf of the Trust  Estate,
shall  provide  financing  from the  Trust  Estate  to any  purchaser  of an REO
Mortgage Loan.



<PAGE>



Section 3.07.                                            Amendments to Servicing
Agreements,
Modification of Standard Provisions.

     (a) Subject to the prior written consent of the Trustee pursuant to Section
3.07(b),  the Master Servicer from time to time may, to the extent  permitted by
the applicable  Servicing  Agreement,  make such modifications and amendments to
such Servicing  Agreement as the Master  Servicer deems necessary or appropriate
to confirm or carry out more  fully the  intent  and  purpose of such  Servicing
Agreement and the duties,  responsibilities  and  obligations to be performed by
the  Servicer  thereunder.  Such  modifications  may  only be  made if they  are
consistent  with the REMIC  Provisions,  as  evidenced by an Opinion of Counsel.
Prior to the issuance of any  modification  or  amendment,  the Master  Servicer
shall  deliver  to  the  Trustee  such  Opinion  of  Counsel  and  an  Officer's
Certificate  setting forth (i) the provision  that is to be modified or amended,
(ii) the modification or amendment that the Master Servicer desires to issue and
(iii) the reason or reasons for such proposed amendment or modification.

     (b) The Trustee shall consent to any amendment or supplement to a Servicing
Agreement  proposed by the Master Servicer  pursuant to Section  3.07(a),  which
consent and amendment shall not require the consent of any  Certificateholder if
it is (i) for the  purpose of curing  any  mistake  or  ambiguity  or to further
effect or  protect  the rights of the  Certificateholders  or (ii) for any other
purpose,  provided such  amendment or supplement  for such other purpose  cannot
reasonably  be  expected to  adversely  affect  Certificateholders.  The lack of
reasonable  expectation  of an  adverse  effect  on  Certificateholders  may  be
established  through the delivery to the Trustee of (i) an Opinion of Counsel to
such effect or (ii) written  notification  from each Rating Agency to the effect
that such  amendment or  supplement  will not result in reduction of the current
rating assigned by that Rating Agency to the Certificates.  Notwithstanding  the
two immediately preceding sentences, the Trustee may, in its discretion, decline
to enter into or consent to any such  supplement or amendment if its own rights,
duties or immunities shall be adversely affected.

     (c)(i)  Notwithstanding  anything to the contrary in this Section 3.07, the
Master   Servicer   from  time  to  time  may,   without   the  consent  of  any
Certificateholder  or the  Trustee,  enter  into an  amendment  (A) to an  Other
Servicing  Agreement for the purpose of (i)  eliminating  or reducing  Month End
Interest and (ii)  providing for the  remittance of Full  Unscheduled  Principal
Receipts by the  applicable  Servicer to the Master  Servicer not later than the
24th day of each month (or if such day is not a Business  Day,  on the  previous
Business  Day) or (B) to the  Norwest  Servicing  Agreement  for the  purpose of
changing  the  applicable  Remittance  Date to the 18th day of each month (or if
such day is not a Business Day, on the previous Business Day).

     (ii)The  Master  Servicer  may  direct  Norwest  Mortgage  to enter into an
amendment  to the Norwest  Servicing  Agreement  for the  purposes  described in
Sections 3.07(c)(i)(B) and 10.01(b)(iii).



<PAGE>



Section 3.08.      Oversight of Servicing.

     The Master Servicer shall  supervise,  monitor and oversee the servicing of
the Mortgage Loans by each Servicer and the  performance by each Servicer of all
services,  duties,  responsibilities  and obligations that are to be observed or
performed  by  the  Servicer  under  its  respective  Servicing  Agreement.   In
performing its obligations hereunder,  the Master Servicer shall act in a manner
consistent with Accepted Master  Servicing  Practices and with the Trustee's and
the  Certificateholders'  reliance  on the  Master  Servicer,  and  in a  manner
consistent with the terms and provisions of any insurance  policy required to be
maintained by the Master Servicer or any Servicer  pursuant to this Agreement or
any Servicing Agreement.  The Master Servicer  acknowledges that prior to taking
certain actions required to service the Mortgage Loans, each Servicing Agreement
provides that the Servicer  thereunder  must notify,  consult  with,  obtain the
consent of or otherwise  follow the  instructions  of the Master  Servicer.  The
Master Servicer is also given  authority to waive  compliance by a Servicer with
certain provisions of its Servicing Agreement. In each such instance, the Master
Servicer  shall  promptly  instruct such  Servicer or otherwise  respond to such
Servicer's  request. In no event will the Master Servicer instruct such Servicer
to take any  action,  give any  consent  to  action  by such  Servicer  or waive
compliance  by such Servicer  with any  provision of such  Servicer's  Servicing
Agreement if any resulting  action or failure to act would be inconsistent  with
the  requirements  of the Rating  Agencies that rated the  Certificates or would
otherwise have an adverse effect on the  Certificateholders.  Any such action or
failure   to  act   shall  be  deemed   to  have  an   adverse   effect  on  the
Certificateholders  if such  action or failure to act either  results in (i) the
downgrading  of the rating  assigned by any Rating  Agency to the  Certificates,
(ii) the loss by the Upper-Tier  REMIC or the  Lower-Tier  REMIC of REMIC status
for  federal  income tax  purposes  or (iii) the  imposition  of any  Prohibited
Transaction  Tax or any  federal  taxes on  either  the  Upper-Tier  REMIC,  the
Lower-Tier REMIC or the Trust Estate.  The Master Servicer shall have full power
and  authority  in its sole  discretion  to take any action with  respect to the
Trust  Estate  as may be  necessary  or  advisable  to avoid  the  circumstances
specified including clause (ii) or (iii) of the preceding sentence.

     For the purposes of determining whether any modification of a Mortgage Loan
shall be  permitted  by the Trustee or the Master  Servicer,  such  modification
shall be  construed as a  substitution  of the  modified  Mortgage  Loan for the
Mortgage  Loan  originally  deposited  in the  Trust  Estate  if it  would  be a
"significant  modification"  within the  meaning of Section  1.860G-2(b)  of the
regulations of the U.S.  Department of the Treasury.  No  modification  shall be
approved  unless (i) the modified  Mortgage  Loan would  qualify as a Substitute
Mortgage Loan under Section 2.02 and (ii) with respect to any modification  that
occurs more than three  months after the Closing Date and is not the result of a
default or a reasonably  foreseeable  default under the Mortgage Loan,  there is
delivered  to the  Trustee an Opinion  of Counsel  (at the  expense of the party
seeking to modify the Mortgage Loan) to the effect that such modification  would
not be treated as giving rise to a new debt  instrument  for federal  income tax
purposes as described in the preceding sentence.

     During the term of this Agreement,  the Master Servicer shall consult fully
with each  Servicer as may be  necessary  from time to time to perform and carry
out the Master



<PAGE>



Servicer's  obligations  hereunder and otherwise exercise  reasonable efforts to
encourage  such Servicer to perform and observe the covenants,  obligations  and
conditions to be performed or observed by it under its Servicing Agreement.

     The relationship of the Master Servicer to the Trustee under this Agreement
is intended by the parties to be that of an independent  contractor and not that
of a joint venturer, partner or agent.

     The Master  Servicer  shall  administer  the Trust  Estate on behalf of the
Trustee  and shall have full power and  authority,  acting  alone or (subject to
Section  6.06) through one or more  subcontractors,  to do any and all things in
connection  with such  administration  which it may deem necessary or desirable.
Upon the execution and delivery of this Agreement,  and from time to time as may
be required  thereafter,  the Trustee shall  furnish the Master  Servicer or its
subcontractors  with any powers of attorney  and such other  documents as may be
necessary  or  appropriate  to  enable  the  Master  Servicer  to carry  out its
administrative duties hereunder.

     The Seller shall be entitled,  at its option,  to repurchase  any defaulted
Mortgage Loan or any Mortgage Loan as to which default is reasonably foreseeable
from the Trust Estate if, in the Seller's judgment, the default is not likely to
be cured by the Mortgagor;  provided,  however,  that the Cut-Off Date Principal
Balances of the Mortgage Loans repurchased  pursuant to this provision shall not
exceed 2.5% of the Cut-Off  Date  Aggregate  Principal  Balance of the  Mortgage
Loans. The purchase price for any such Mortgage Loan shall be 100% of the unpaid
principal  balance of such  Mortgage Loan plus accrued  interest  thereon at the
Mortgage  Interest  Rate  through  the  last  day of the  month  in  which  such
repurchase occurs.  Upon the receipt of such purchase price, the Master Servicer
shall provide to the Trustee the certification  required by Section 3.04 and the
Trustee and the  Custodian,  if any,  shall  promptly  release to the Seller the
Owner Mortgage Loan File relating to the Mortgage Loan being repurchased.

     In the event  that (i) the  Master  Servicer  determines  at any time that,
notwithstanding the representations and warranties set forth in Section 2.03(b),
any Mortgage  Loan is not a "qualified  mortgage"  within the meaning of Section
860G of the  Code  and (ii)  the  Master  Servicer  is  unable  to  enforce  the
obligation of the Seller to purchase such Mortgage Loan pursuant to Section 2.02
within two months of such  determination,  the Master  Servicer shall cause such
Mortgage  Loan to be auctioned  to the highest  bidder and sold out of the Trust
Estate no later than the date 90 days after such determination.  In the event of
any such sale of a Mortgage Loan, the Trustee shall,  at the written  request of
the Master  Servicer and upon being supported with  appropriate  forms therefor,
within five Business Days of the deposit by the Master  Servicer of the proceeds
of such auction into the Certificate Account, release or cause to be released to
the entity  identified by the Master  Servicer the related  Owner  Mortgage Loan
File and  Servicer  Mortgage  Loan  File and  shall  execute  and  deliver  such
instruments of transfer or assignment,  in each case without recourse,  as shall
be necessary to vest in the auction purchaser title to the Mortgage Loan and the
Trustee shall have no further  responsibility with regard to such Owner Mortgage
Loan File or Servicer Mortgage Loan File.



<PAGE>



Neither the Trustee,  the Master Servicer nor any Servicer,  acting on behalf of
the Trustee, shall provide financing from the Trust Estate to any purchaser of a
Mortgage Loan.

     The Master  Servicer,  on behalf of the  Trustee,  shall,  pursuant  to the
Servicing  Agreements,   object  to  the  foreclosure  upon,  or  other  related
conversion of the ownership of, any Mortgaged  Property by the related  Servicer
if (i) the Master Servicer believes such Mortgaged  Property may be contaminated
with or  affected  by  hazardous  wastes or  hazardous  substances  or (ii) such
Servicer does not agree to administer such Mortgaged Property,  once the related
Mortgage  Loan becomes an REO Mortgage  Loan, in a manner which would not result
in a federal tax being imposed upon the Trust Estate or the Upper-Tier  REMIC or
Lower-Tier REMIC.

     The Master  Servicer may enter into a special  servicing  agreement with an
unaffiliated  holder of 100%  Percentage  Interest  of a Class B  Subclass  or a
holder  of  a  class  of  securities  representing  interests  in  the  Class  B
Certificates and/or other subordinated mortgage pass-through certificates,  such
agreement to be substantially in the form of Exhibit M hereto or subject to each
Rating Agency's  acknowledgment  that the ratings of the  Certificates in effect
immediately prior to the entering into of such agreement would not be qualified,
downgraded  or  withdrawn  and the  Certificates  would  not be placed on credit
review status (except for possible upgrading) as a result of such agreement. Any
such  agreement  may contain  provisions  whereby  such holder may  instruct the
Master  Servicer to instruct a Servicer to the extent provided in the applicable
Servicing Agreement to commence or delay foreclosure proceedings with respect to
delinquent Mortgage Loans and will contain provisions for the deposit of cash by
the holder that would be available for  distribution  to  Certificateholders  if
Liquidation Proceeds are less than they otherwise may have been had the Servicer
acted in accordance with its normal procedures.

Section 3.09.      Termination and Substitution of Servicing Agreements.

     Upon the  occurrence  of any event for which a Servicer  may be  terminated
pursuant to its Servicing Agreement,  the Master Servicer shall promptly deliver
to the Seller and the Trustee an Officer's Certificate  certifying that an event
has  occurred  which  may  justify  termination  of  such  Servicing  Agreement,
describing the circumstances surrounding such event and recommending what action
should be taken by the  Trustee  with  respect to such  Servicer.  If the Master
Servicer  recommends  that such Servicing  Agreement be  terminated,  the Master
Servicer's  certification  must state that the breach is material and not merely
technical in nature.  Upon written direction of the Master Servicer,  based upon
such  certification,   the  Trustee  shall  promptly  terminate  such  Servicing
Agreement. Notwithstanding the foregoing, in the event that (i) Norwest Mortgage
fails to make any advance, as a consequence of which the Trustee is obligated to
make an advance  pursuant to Section 3.03 and (ii) the Trustee  provides Norwest
Mortgage  written  notice of the failure to make such  advance and such  failure
shall continue  unremedied for a period of 15 days after receipt of such notice,
the  Trustee  shall  terminate  the  Norwest  Servicing  Agreement  without  the
recommendation  of the Master Servicer.  The Master Servicer shall indemnify the
Trustee and hold it harmless  from and against any and all claims,  liabilities,
costs and expenses (including, without limitation, reasonable attorneys' fees)



<PAGE>



arising out of, or assessed  against the Trustee in connection with  termination
of such  Servicing  Agreement at the  direction of the Master  Servicer.  If the
Trustee  terminates  such  Servicing  Agreement,  the  Trustee  may enter into a
substitute  Servicing  Agreement  with the  Master  Servicer  or, at the  Master
Servicer's nomination,  with another mortgage loan service company acceptable to
the Trustee,  the Master  Servicer and each Rating Agency under which the Master
Servicer or such substitute servicer, as the case may be, shall assume, satisfy,
perform and carry out all liabilities,  duties, responsibilities and obligations
that are to be, or otherwise were to have been, satisfied, performed and carried
out by such Servicer under such terminated Servicing Agreement.  Until such time
as the Trustee enters into a substitute  servicing agreement with respect to the
Mortgage Loans previously  serviced by such Servicer,  the Master Servicer shall
assume,  satisfy,  perform and carry out all obligations which otherwise were to
have been  satisfied,  performed  and  carried  out by such  Servicer  under its
terminated Servicing  Agreement.  However, in no event shall the Master Servicer
be deemed to have assumed the  obligations of a Servicer to advance  payments of
principal  and  interest on a delinquent  Mortgage  Loan in excess of the Master
Servicer's  independent  Periodic Advance  obligation under Section 3.03 of this
Agreement.  As compensation for the Master Servicer of any servicing obligations
fulfilled  or assumed  by the Master  Servicer,  the  Master  Servicer  shall be
entitled  to any  servicing  compensation  to which a  Servicer  would have been
entitled if the Servicing Agreement with such Servicer had not been terminated.

Section 3.10.      1934 Act Reports.

     The  Master  Servicer  shall,  on behalf of the  Seller,  make all  filings
required  to be made by the  Seller  with  respect  to the Class A  Certificates
(other than the Class A-7 Certificates),  the Class M Certificates and the Class
B-1 and Class B-2 Certificates  pursuant to the Securities Exchange Act of 1934,
as amended.

     Notwithstanding  the  foregoing,  after the  Principal  Balance or notional
amount of any Class or Subclass  (other  than the Class A-7,  Class A-R or Class

Certificates,  after the latter to occur of (i) the Class A  Subclass  Principal
Balance  of such  Subclass  has been  reduced to zero or (ii) the Class A-1 IO A
Component  Notional Amount,  Class A-1 IO B Component  Notional Amount and Class
A-1 IO C  Component  Notional  Amount have been  reduced to zero,  such Class or
Subclass will be entitled to no further  distributions  of principal or interest
(including, without limitation, any Unpaid Interest Shortfalls).

     In  addition,  Net  Foreclosure  Profits,  if  any,  with  respect  to such
Distribution  Date minus any portion thereof  payable to a Servicer  pursuant to

Subclasses of Class A Certificates  (other than the Class A-PO Certificates) pro
rata based on the Class A Subclass Principal Balances.

     (ii)Distributions  on the  Uncertificated  Lower-Tier  Interests.  On  each
Distribution  Date,  each  Uncertificated   Lower-Tier  Interest  shall  receive
distributions  in  respect  of  principal  in an amount  equal to the  amount of
principal distributed to its respective Corresponding Upper-Tier Class, Classes,
Component or Components as provided herein. On each Distribution Date, the Class
A-LWIO Interest shall receive  distributions in respect of interest in an amount
equal to the Interest  Distributions in respect of its Corresponding  Upper-Tier
Class,  Classes,  Component or Components,  in each case to the extent  actually
distributed  thereon.  On each  Distribution  Date the Class A-L1 Interest shall
receive  distributions  in respect of interest in an amount  equal to the sum of
(i) the Interest Distributions in respect of its Corresponding Upper-Tier Class,
Classes,  Component or Components and (ii) an amount equal to the product of the
Class A-L1 Interest  Fraction and the Interest  Distributions  in respect of the
Class  A-11  Certificates  and the Class  A-7 IO C  Component;  the  Class  A-L2
Interest shall receive  distributions  in respect of interest in an amount equal
to the sum of (i) the  Interest  Distributions  in respect of its  Corresponding

Class A-L8 Interest  Fraction and the Interest  Distributions  in respect of the
Class  A-11  Certificates  and the Class  A-7 IO C  Component;  the Class  A-LUR
Interest shall receive  distributions  in respect of interest in an amount equal

Interest shall receive  distributions  in respect of interest in an amount equal
to the sum of (i) the  Interest  Distributions  in respect of its  Corresponding

the product of the Class B-L4 Interest  Fraction and the Interest  Distributions
in respect of the Class A-11 Certificates and the Class A-7 IO C Component;  the
Class B-L5  Interest  shall receive  distributions  in respect of interest in an
amount  equal to the sum of (i) the  Interest  Distributions  in  respect of its
Corresponding  Upper-Tier  Class,  Classes,  Component or Components and (ii) an
amount equal to the product of the Class B-L5 Interest Fraction and the Interest
Distributions  in respect of the Class A-11  Certificates and the Class A-7 IO C
Component.  Such amounts distributed to the Uncertificated  Lower-Tier Interests
in respect of principal and interest with respect to any  Distribution  Date are
referred to herein collectively as the "Lower-Tier Distribution Amount."

     As of any date,  the principal  balance of each  Uncertificated  Lower-Tier
Interest  (other  than the Class  A-LWIO  Interest)  equals the Class A Subclass
Principal Balances,  Component Principal Balances,  Class M Principal Balance or
Class B  Subclass  Principal  Balance,  as the  case may be,  of the  respective
Corresponding  Upper-Tier  Class,  Classes,  Component or Components.  The Class
A-LWIO Interest has no principal balance. The



<PAGE>



notional amount of the Class A-LWIO Interest equals the notional  amounts of its
Corresponding  Upper-Tier Class, Classes,  Component or Components.  The initial
principal  balance of each  Uncertificated  Lower-Tier  Interest (other than the
Class A-LWIO Interest) equals the Original Class A Subclass Principal  Balances,
Original  Component  Principal  Balances,  Original  Class M Principal  Balance,
Original  Class B-1 Principal  Balance,  Original  Class B-2 Principal  Balance,
Original Class B-3 Principal  Balance,  Original Class B-4 Principal  Balance or
Original  Class B-5  Principal  Balance  as the case may be,  of the  respective
Corresponding  Upper-Tier Class, Classes,  Component or Components.  The initial
notional amount of the Class A-LWIO Interest equals the initial notional amounts
of its Corresponding Class, Classes, Component or Components.

     The  pass-through  rate  with  respect  to each  Uncertificated  Lower-Tier
Interest  (other than the Class A-LPO Interest and Class A-LWIO  Interest) shall
be  7.500%  per  annum.  Prior to the  Class  A-7  Scheduled  Accrual  Component
Accretion  Termination  Date,  interest will accrue in respect of the Class A-L7
Interest and will be added to the principal  balance  thereof to the same extent
that  interest  accrues and is added to the Component  Principal  Balance of the
Class  A-7  Scheduled  Accrual  Component.  Prior  to the  Class  A-8  Accretion
Termination Date, interest will accrue in respect of the Class A-L8 Interest and
will be added to the principal  balance thereof to the same extent that interest
accrues and is added to the Class A Subclass  Principal Balance of the Class A-8
Certificates.  The  pass-through  rate with respect to the Class A-LWIO Interest
shall be the Class  A-WIO  Pass-Through  Rate.  The Class  A-LPO  Interest  is a
principal-only  interest and is not entitled to distributions  of interest.  Any
Non-Supported  Interest  Shortfalls  will be  allocated  to each  Uncertificated
Lower-Tier Interest in the same relative proportions as interest is allocated to
such Uncertificated Lower-Tier Interest.

     (b)  The  Class  A-10,   Class  A-11  and  Class  A-WIO   Certificates  are
interest-only  Certificates  and are not entitled to distributions in respect of
principal.

     On each  Distribution  Date  occurring  prior to the  Class  A-8  Accretion
Termination Date, an amount equal to the Class A-8 Accrual  Distribution Amount,
if any, for such Distribution  Date will be allocated as follows:  first, to the
Class A-7 Scheduled Accrual Component without regard to its Scheduled  Principal
Amount for such Distribution Date until the Component  Principal Balance thereof
has been  reduced to zero and second,  to the Class A-8  Certificates  until the
Class A Subclass Principal Balance thereof has been reduced to zero.

     On each  Distribution  Date  occurring  prior to the  Class  A-7  Scheduled
Accrual Component  Accretion  Termination Date, an amount equal to the Class A-7
Scheduled Accrual Component  Distribution  Amount, if any, for such Distribution
Date will be allocated as follows;  first,  concurrently,  86.1052093057% to the
Class A-5  Certificates and  13.8947906943%  to the Class A-4 Certificates up to
their  respective  PAC Principal  Amounts for such  Distribution  Date,  second,
concurrently, 86.1052147803% to the Class A-6 Certificates and 13.8947852197% to
the Class A-4 Certificates up to their respective PAC Principal Amounts for such
Distribution Date, and third, to the Class A-7 Scheduled Accrual



<PAGE>



Component, without regard to its Scheduled Principal Amount, until the Component
Principal Balance thereof has been reduced to zero.

     On each Distribution Date occurring prior to the Cross-Over Date, the Class
A Non-PO  Principal  Distribution  Amount  (other  than the Class A-7  Scheduled
Accrual  Component  Distribution  Amount and the Class A-8 Accrual  Distribution

     (c) Notwithstanding  the foregoing,  on each Distribution Date occurring on
or subsequent to the Cross-Over Date, the Class A Non-PO Principal  Distribution
Amount shall be distributed among the Subclasses of Class A Certificates  (other
than the Class A-PO  Certificates) pro rata in accordance with their outstanding
Class A Subclass  Principal Balances without regard to either the proportions or
the priorities set forth in Section 4.01(b).

     (d) (i) For  purposes  of  determining  whether the  Subclasses  of Class B
Certificates are eligible to receive  distributions of principal with respect to
any Distribution Date, the following tests shall apply:

          (A) if the  Current  Class M  Fractional  Interest  is less  than  the
     Original Class M Fractional  Interest and the Class M Principal  Balance is
     greater than zero, the Class B-1, Class B-2, Class B-3, Class B-4 and Class
     B-5  Certificates  shall  not  be  eligible  to  receive  distributions  of
     principal; or

          (B) if the  Current  Class B-1  Fractional  Interest  is less than the
     Original Class B-1 Fractional  Interest and the Class B-1 Principal Balance
     is greater  than zero,  the Class B-2,  Class B-3,  Class B-4 and Class B-5
     Certificates  shall not be eligible to receive  distributions of principal;
     or

          (C) if the  Current  Class B-2  Fractional  Interest  is less than the
     Original Class B-2 Fractional  Interest and the Class B-2 Principal Balance
     is greater than zero, the Class B-3,  Class B-4 and Class B-5  Certificates
     shall not be eligible to receive distributions of principal; or

          (D) if the  Current  Class B-3  Fractional  Interest  is less than the
     Original Class B-3 Fractional  Interest and the Class B-3 Principal Balance
     is greater than zero, the Class B-4 and Class B-5 Certificates shall not be
     eligible to receive distributions of principal; or

          (E) if the  Current  Class B-4  Fractional  Interest  is less than the
     Original Class B-4 Fractional  Interest and the Class B-4 Principal Balance
     is greater than zero, the Class B-5  Certificates  shall not be eligible to
     receive distributions of principal.

     (ii)Notwithstanding   the  foregoing,  if  on  any  Distribution  Date  the
aggregate  distributions  to  Holders  of the Class M  Certificates  and/or  the
Subclasses  of  Class  B  Certificates  entitled  to  receive  distributions  of
principal would reduce the Class M Principal Balance and/or the Class B Subclass
Principal Balances of the Subclasses of Class B Certificates entitled to receive
distributions of principal below zero,  first the Class M Prepayment  Percentage
and/or  the Class B  Subclass  Prepayment  Percentage  of any  affected  Class B
Subclass for such  Distribution  Date beginning with the affected  Subclass with
the lowest numerical  Subclass  designation and then, if necessary,  the Class M
Percentage and/or the Class B Subclass  Percentage of such Subclass of the Class
B  Certificates  for such  Distribution  Date shall be reduced to the respective
percentages  necessary to bring the Class M Principal Balance and/or the Class B
Subclass Principal Balance of such Class B Subclass to



<PAGE>



zero.  The Class B  Subclass  Prepayment  Percentages  and the Class B  Subclass
Percentages of the remaining Class B Subclasses will be recomputed  substituting
for the Subordinated  Prepayment Percentage and Subordinated  Percentage in such
computations the difference between (A) the Subordinated  Prepayment  Percentage
or  Subordinated  Percentage,  as the  case  may be,  and  (B)  the  percentages
determined in  accordance  with the  preceding  sentence  necessary to bring the
Class M Principal Balance and/or the Class B Subclass  Principal Balances of the
affected  Class B Subclasses  to zero;  provided,  however,  that if the Class B
Subclass  Principal  Balances of all the Class B Subclasses  eligible to receive
distributions of principal shall be reduced to zero on such  Distribution  Date,
the Class B Subclass  Prepayment  Percentage and the Class B Subclass Percentage
of the Class B Subclass with the lowest  numerical  Subclass  designation  which
would  otherwise  be  ineligible  to  receive   distributions  of  principal  in
accordance  with this  Section  shall equal the  remainder  of the  Subordinated
Prepayment  Percentage for such  Distribution  Date minus the sum of the Class M
Prepayment  Percentage  and the Class B Subclass  Prepayment  Percentages of the
Class B Subclasses having lower numerical Subclass designations, if any, and the
remainder of the Subordinated  Percentage for such  Distribution  Date minus the
sum of the Class M Percentage and the Class B Subclass  Percentages of the Class
B Subclasses having lower numerical Subclass designations, if any, respectively.
Any entitlement of any Class B Subclass to principal payments solely pursuant to
this clause (ii) shall not cause such Subclass to be regarded as being  eligible
to receive principal distributions for the purpose of applying the definition of
its Class B Subclass Percentage or Class B Subclass Prepayment Percentage.

     (e) The Trustee  shall  establish and maintain the  Upper-Tier  Certificate
Account,  which shall be a separate  trust account and an Eligible  Account.  On
each  Distribution  Date other than the Final  Distribution  Date (if such Final
Distribution  Date is in  connection  with a purchase of the assets of the Trust
Estate by the Seller), the Paying Agent shall, on behalf of the Master Servicer,
from  funds  available  on deposit  in the  Payment  Account,  (i)  deposit,  in
immediately available funds, by wire transfer or otherwise,  into the Upper-Tier
Certificate  Account the Lower-Tier  Distribution  Amount and (ii) distribute to
the Class  A-LR  Certificateholder  (other  than as  provided  in  Section  9.01
respecting the final distribution to Certificateholders) by check mailed to such
Holder at the address of such Holder appearing in the Certificate Register,  the
Class A Subclass  Distribution Amount with respect to the Class A-LR Certificate
and all other amounts  distributable to the Class A-LR Certificate.  The Trustee
may clear and terminate the Upper-Tier  Certificate  Account pursuant to Section
9.01.

     (f) On each  Distribution  Date other than the Final  Distribution Date (if
such Final  Distribution  Date is in connection with a purchase of the assets of
the Trust Estate by the Seller), the Paying Agent shall, on behalf of the Master
Servicer,  from funds remitted to it by the Master Servicer,  distribute to each
Certificateholder of record (other than the Class A-LR Certificateholder) on the
preceding  Record Date (other than as provided in Section  9.01  respecting  the
final  distribution  to  Certificateholders  or in the  last  paragraph  of this
Section  4.01(f)  respecting the final  distribution  in respect of any Class or
Subclass) either in immediately  available funds by wire transfer to the account
of  such  Certificateholder  at  a  bank  or  other  entity  having  appropriate
facilities therefor, if such Certificateholder holds Certificates



<PAGE>



having a Denomination at least equal to that specified in Section 11.27, and has
so notified  the Master  Servicer or, if  applicable,  the Paying Agent at least
seven  Business  Days prior to the  Distribution  Date or, if such Holder  holds
Certificates  having,  in the aggregate,  a Denomination less than the requisite
minimum  Denomination  or if such Holder holds the Class A-R  Certificate or has
not so notified the Paying Agent,  by check mailed to such Holder at the address
of such Holder appearing in the Certificate Register, such Holder's share (based
on, with respect to each Class or  Subclass,  the  aggregate  of the  Percentage
Interests  represented by  Certificates  of the applicable  Class or Subclass of
Certificates  held by such  Holder of the Class A Subclass  Distribution  Amount
with respect to each Subclass of Class A Certificates,  the Class M Distribution
Amount  with  respect  to the  Class M  Certificates  and the  Class B  Subclass
Distribution Amount with respect to each such Subclass of Class B Certificates.

     In the event that, on any Distribution Date prior to the Final Distribution
Date,  the  Class A  Subclass  Principal  Balance  of any  Subclass  of  Class A
Certificates  (other than the Class A-7,  Class A-10,  Class A-11,  Class A-WIO,
Class A-R or A-LR  Certificates),  the Class M Principal  Balance of the Class M
Certificates or the Class B Subclass  Principal Balance of any Subclass of Class
B  Certificates  would be  reduced  to zero or (i) in the case of the  Class A-7
Certificates, upon the later of (a) the Class A Subclass Principal Balance being
reduced to zero or (b) the Class A-7 IO A Component  Notional Amount,  Class A-7
IO B  Component  Notional  Amount and Class A-7 IO C Component  Notional  Amount
being  reduced  to zero,  (ii) in the case of the Class A-10  Certificates,  the
Class A-10  Notional  Amount would be reduced to zero,  (iii) in the case of the
Class A-11 Certificates, the Class A-11 Notional Amount would be reduced to zero
or (iv) in the case of the Class A-WIO  Certificates,  the Class A-WIO  Notional
Amount  would  be  reduced  to  zero,  the  Master  Servicer  shall,  as soon as
practicable  after the Determination  Date relating to such  Distribution  Date,
send a notice  to the  Trustee.  The  Trustee  will  then  send a notice to each
Certificateholder  of such  Class  or  Subclass  with a copy to the  Certificate
Registrar,  specifying that the final distribution with respect to such Class or
Subclass will be made on such  Distribution  Date only upon the presentation and
surrender of such  Certificateholder's  Certificates  at the office or agency of
the Trustee therein specified;  provided, however, that the failure to give such
notice will not entitle a Certificateholder  to any interest beyond the interest
payable  with  respect to such  Distribution  Date in  accordance  with  Section
4.01(a)(i).

     (g) The  Paying  Agent (or if no Paying  Agent is  appointed  by the Master
Servicer,  the Master  Servicer)  shall  withhold or cause to be  withheld  such
amounts as may be required  by the Code  (giving  full effect to any  exemptions
from  withholding  and  related  certifications  required  to  be  furnished  by
Certificateholders  and any reductions to withholding by virtue of any bilateral
tax  treaties  and any  applicable  certification  required to be  furnished  by
Certificateholders  with  respect  thereto)  from  distributions  to be  made to
persons other than U.S. Persons ("Non-U.S.  Persons"). Amounts withheld pursuant
to this  Section  4.01(g)  shall be treated as having  been  distributed  to the
related  Certificateholder for all purposes of this Agreement.  For the purposes
of this  paragraph,  a "U.S.  Person"  is a citizen  or  resident  of the United
States,  a  corporation,  partnership or other entity created or organized in or
under the laws of the United States or any  political  subdivision  thereof,  an
estate that is subject to United  States  federal  income tax  regardless of the
source of its income or a trust if (i) for taxable years

Section 4.02.      Allocation of Realized Losses.

     (a) With  respect  to any  Distribution  Date,  the  principal  portion  of
Realized  Losses  (other than Debt Service  Reductions,  Excess  Special  Hazard
Losses,  Excess Fraud Losses and Excess Bankruptcy  Losses) will be allocated as
follows:

     first, to the Class B-5 Certificates  until the Class B-5 Principal Balance
has been reduced to zero;

     second, to the Class B-4 Certificates until the Class B-4 Principal Balance
has been reduced to zero;

     third, to the Class B-3 Certificates  until the Class B-3 Principal Balance
has been reduced to zero;

     fourth, to the Class B-2 Certificates until the Class B-2 Principal Balance
has been reduced to zero;

     fifth, to the Class B-1 Certificates  until the Class B-1 Principal Balance
has been reduced to zero;

     sixth, to the Class M Certificates  until the Class M Principal Balance has
been reduced to zero; and

     seventh,  concurrently,  to the Class A Certificates  (other than the Class
A-PO  Certificates) and Class A-PO  Certificates,  pro rata, based on the Non-PO
Fraction and the PO Fraction, respectively.

     This allocation of Realized  Losses will be effected  through the reduction
of the applicable Class's or Subclass's Principal Balance.

     (b) With respect to any Distribution  Date, the principal portion of Excess
Special  Hazard  Losses,  Excess  Fraud  Losses  and  Excess  Bankruptcy  Losses
occurring  with  respect  to any  Mortgage  Loan  allocable  to the  Class  A-PO
Certificates will equal the product of the amount of any such principal loss and
the PO Fraction for such  Mortgage  Loan.  The  principal  portion of any Excess
Special  Hazard  Losses,  Excess  Fraud  Losses  and  Excess  Bankruptcy  Losses
remaining after allocation to the Class A-PO Certificates in accordance with the
preceding  sentence  shall be allocated pro rata among the Class A  Certificates
(other  than the Class  A-PO  Certificates),  Class M  Certificates  and Class B
Certificates  based on the Class A Non-PO Principal  Balance,  Class M Principal
Balance and the Class B Principal Balance,

respectively.  Any such  loss  allocated  to the Class A  Certificates  shall be
allocated on the subsequent  Determination Date among the outstanding Subclasses
of Class A Certificates  (other than the Class A-7  Certificates)  and the Class
A-7 Scheduled  Accrual  Component in  accordance  with the Class A Subclass Loss
Percentage and Component Loss  Percentages  as of such  Determination  Date. Any
such loss  allocated to the Class B  Certificates  shall be  allocated  pro rata
among the outstanding  Subclasses of Class B Certificates based on their Class B
Subclass Principal Balances.

     (c) Any Realized Losses  allocated to a Subclass of Class A Certificates or
Class B Certificates or to the Class M Certificates  pursuant to Section 4.02(a)
or Section 4.02(b) shall be allocated among the Certificates of such Subclass or
Class based on their Percentage Interests.

     (d) In the event  that  there is a  Recovery  of an amount  in  respect  of
principal of a Mortgage Loan which had  previously  been allocated as a Realized
Loss to any Subclasses of Class A Certificates,  the Class M Certificates or any
Subclasses of Class B Certificates,  each outstanding Class or Subclass to which
such Realized Loss had previously  been allocated shall be entitled to its share
(with respect to the Class A-PO  Certificates,  based on the PO Fraction of such
Mortgage  Loan and,  with  respect to the Class A  Certificates  (other than the
Class A-PO Certificates),  Class M Certificates and Class B Certificates,  based
on their pro rata share of the Non-PO  Fraction of such  Mortgage  Loan) of such
Recovery up to the amount of such  Realized  Loss  previously  allocated to such
Class or Subclass on the  Distribution  Date in the month following the month in
which  such  recovery  is  received.  When the  Principal  Balance of a Class or
Subclass of Certificates  has been reduced to zero, such Class or Subclass shall
not be entitled to any share of such  Recovery.  In the event that the amount of
such Recovery exceeds the amount of such recovery  allocated to each outstanding
Class or Subclass in accordance with the preceding provisions,  each outstanding
Class  or  Subclass  shall be  entitled  to its pro rata  share  (determined  as
described  above) of such  excess up to the amount of any  unrecovered  Realized
Loss  previously  allocated  to such  Class  or  Subclass.  Notwithstanding  the
foregoing  provisions,  but subject to the following  proviso,  if such Recovery
occurs within two years of the realization of such loss and (i) is the result of
an event that would have given rise to the  repurchase  of the related  Mortgage
Loan by the Seller pursuant to Section 2.02 or 2.03, or (ii) represents in whole
or part  funds  which the  applicable  Servicer  had  received  in  respect of a
Liquidated  Loan but failed to remit to the  Certificate  Account on or prior to
the Business Day  preceding  the  Distribution  Date  following  the  Applicable
Unscheduled  Principal  Receipt  Period  in which  the  Mortgage  Loan  became a
Liquidated  Loan  such  Recovery  may,  at the  sole  discretion  of the  Master
Servicer,  be treated as a repurchase or an Unscheduled  Principal  Receipt with
respect to such Mortgage Loan, as the case may be, the Realized Loss  previously
recognized may be reversed and treated for all subsequent  purposes as if it had
never occurred and the Master Servicer may make such  adjustments to interest or
principal distributions on the Certificates and to the principal balances of the
Certificates  as the  Master  Servicer  in its  good  faith  judgment  and  sole
discretion  deems  necessary  or  desirable  to  effectuate  the reversal of the
Realized  Loss  and  the  treatment  of such  amount  as a  repurchase  or as an
Unscheduled Principal Receipt, as the case may be; provided that such actions do
not result in the aggregate distributions made in respect



<PAGE>



of each  Class and  Subclass  of  Certificates  whose  principal  balances  were
previously  reduced as a result of such Realized Loss being less than such Class
or Subclass  would have  received if such  Recovery  had been  deposited  in the
Certificate  Account on or prior to the Business Day preceding the  Distribution
Date following the Applicable  Unscheduled Principal Receipt Period in which the
Mortgage Loan became a Liquidated Loan.

     (e) The interest  portion of Excess  Special  Hazard  Losses,  Excess Fraud
Losses  and  Excess  Bankruptcy  Losses  shall be  allocated  among  the Class A
Certificates,  Class M Certificates and Class B Certificates,  pro rata based on
the Class A Interest Accrual Amount, the Class M Interest Accrual Amount and the
Class B Interest  Accrual  Amount for the  related  Distribution  Date,  without
regard to any reduction  pursuant to this  sentence.  Any such loss allocated to
the Class A Certificates shall be allocated among the outstanding  Subclasses of
Class A Certificates  (other than the Class A-7  Certificates) and the Class A-7
Components  based on their Class A Subclass  Interest  Percentages and Component
Interest Percentages, as the case may be. Any such loss allocated to the Class B
Certificates  will be  allocated  among the  outstanding  Subclasses  of Class B
Certificates based on their Class B Subclass Interest Percentages.  In addition,
after the Class M Principal  Balance and the Class B Principal Balance have been
reduced to zero,  the  interest  portion of Realized  Losses  (other than Excess
Special Hazard Losses, Excess Fraud Losses and Excess Bankruptcy Losses) will be
allocated among the outstanding  Subclasses of Class A Certificates  (other than
the Class A-7  Certificates) and the Class A-7 Components based on their Class A
Subclass Interest  Percentages and Component Interest  Percentages,  as the case
may be.

     (f) Realized Losses  allocated in accordance with this Section 4.02 will be
allocated on the  Determination  Date in the second month following the month in
which such loss was incurred with respect to the preceding Distribution Date.

     (g) With  respect  to any  Distribution  Date,  the  principal  portion  of
Realized  Losses and recoveries  attributable to previously  allocated  Realized
Losses  allocated  pursuant  to this  Section  4.02  will be  allocated  to each
Uncertificated Lower-Tier Interest in an amount equal to the amount allocated to
its respective Corresponding Upper-Tier Class, Classes,  Component or Components
as provided above.

     With respect to any  Distribution  Date,  the interest  portion of Realized
Losses  allocated  pursuant  to this  Section  4.02  will be  allocated  to each
Uncertificated  Lower-Tier Interest in the same relative proportions as interest
is allocated to such Uncertificated Lower-Tier Interest.

Section 4.03.      Paying Agent.

     (a) The Master Servicer hereby appoints the Trustee as initial Paying Agent
to make distributions to Certificateholders and to forward to Certificateholders
the periodic  statements and the annual  statements  required by Section 4.04 as

     Certificateholders until such amounts are distributed to Certificateholders
     or otherwise disposed of as herein provided;

          (ii) give the Trustee notice of any default by the Master  Servicer in
     remitting any required amount; and

          (iii) at any time during the continuance of any such default, upon the
     written  request of the Trustee,  forthwith  pay to the Trustee all amounts
     held in trust by such Paying Agent.

     (b) The Paying Agent shall establish and maintain a Payment Account,  which
shall be a separate trust account and an Eligible  Account,  in which the Master
Servicer shall cause to be deposited from funds in the  Certificate  Account or,
to the  extent  required  hereunder,  from its own funds (i) at or before  10:00

shall mature not later than the Business Day preceding the related  Distribution
Date (unless the Eligible  Investments are obligations of the Trustee,  in which
case such  Eligible  Investments  shall  mature not later than the  Distribution
Date),  and shall not be sold or disposed of prior to  maturity.  All income and
gain  realized from any such  investment  shall be for the benefit of the Master
Servicer and shall be subject to its  withdrawal or order from time to time. The
amount of any  losses  incurred  in  respect  of any such  investments  shall be
deposited  in the Payment  Account by the Master  Servicer  out of its own funds
immediately as realized.  The Paying Agent may withdraw from the Payment Account
any  amount  deposited  in the  Payment  Account  that  was not  required  to be
deposited  therein and may clear and terminate the Payment  Account  pursuant to
Section 9.01.

interest  in a  Mortgaged  Property  through  foreclosure  or  other  comparable
conversion in full or partial  satisfaction  of a Mortgage Loan serviced by such
Servicer, or (ii) knows or has reason to know that a Mortgaged Property has been

allow the Master  Servicer  to, for each year  ending  after the  Cut-Off  Date,
provide,  or cause to be  provided,  to the  Internal  Revenue  Service  and the
Mortgagors such  information as is required under Code Sections 6050H (regarding
payment of interest) and 6050P (regarding cancellation of indebtedness).

Section 4.06       Calculation of Amounts; Binding Effect of
Interpretations and Actions of Master Servicer.

     The Master Servicer will compute the amount of all distributions to be made
on the Certificates and all losses to be allocated to the  Certificates.  In the
event that the Master  Servicer  concludes  that any  ambiguity  or  uncertainty
exists in any provisions of this Agreement  relating to distributions to be made
on the  Certificates  or the  allocation  of  losses  to the  Certificates,  the
interpretation  of such  provisions and any actions taken by the Master Servicer
in  good  faith  to  implement  such   interpretation   shall  be  binding  upon
Certificateholders.

aggregate Original Class B Subclass Principal Balance of such Class or Subclass,
as the case may be),  and shall be  substantially  in the  respective  forms set
forth as Exhibits A-1, A-2, A-3, A-4, A-5, A-6, A-7, A-8, A-9, A-10, A-11, A-PO,
A-WIO,  A-R,  A-LR,  B-1,  B-2,  B-3,  B-4,  B-5,  C,  and D  (reverse  side  of
Certificates)  hereto. On original issue the Certificates  shall be executed and
delivered  by the Trustee to or upon the order of the Seller upon receipt by the
Trustee  or the  Custodian  of the  documents  specified  in Section  2.01.  The
aggregate principal portion (or notional amount) evidenced by the Class A, Class
M and Class B  Certificates  shall be the sum of the  amounts  specifically  set
forth in the  respective  Certificates.  The  Certificates  shall be executed by
manual  or  facsimile  signature  on behalf of the  Trustee  by any  Responsible
Officer  thereof.  Certificates  bearing the manual or facsimile  signatures  of
individuals  who were at any time the proper  officers of the Trustee shall bind
the Trustee  notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the  authentication and delivery of such Certificates
or did not hold such offices at the date of such  Certificates.  No  Certificate
shall be  entitled  to any  benefit  under this  Agreement,  or be valid for any
purpose,  unless manually countersigned by a Responsible Officer of the Trustee,
or unless there  appears on such  Certificate a  certificate  of  authentication
executed   by  the   Authenticating   Agent  by  manual   signature,   and  such
countersignature or certificate upon a 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.

     Until such time as Definitive  Certificates  are issued pursuant to Section
5.07, each Book-Entry Certificate shall bear the following legend:

     "Unless this  certificate is presented by an authorized  representative  of
[the Clearing  Agency] to the Trustee or its agent for registration of transfer,
exchange or payment,  and any  certificate  issued is  registered in the name of
[the  Clearing  Agency]  or  such  other  name  as  requested  by an  authorized
representative of [the Clearing Agency] and any payment



<PAGE>



is made to [the Clearing Agency],  any transfer,  pledge or other use hereof for
value or otherwise by or to any person is wrongful  since the  registered  owner
hereof, [the Clearing Agency], has an interest herein."

     (b) Upon original issuance, the Book-Entry  Certificates shall be issued in
the  form  of one or  more  typewritten  certificates,  to be  delivered  to The
Depository Trust Company,  the initial Clearing Agency, by, or on behalf of, the
Seller.  Such  Certificates  shall  initially be registered  in the  Certificate
Register  in the name of the  nominee of the  initial  Clearing  Agency,  and no
Beneficial  Owner  will  receive  a  definitive  certificate  representing  such
Beneficial Owner's interest in the Book-Entry  Certificates,  except as provided
in Section 5.07.  Unless and until  definitive,  fully  registered  certificates
("Definitive  Certificates")  have been issued to Beneficial  Owners pursuant to
Section 5.07:

          (i) the provisions of this Section  5.01(b) shall be in full force and
     effect;

          (ii) the Seller,  the Master Servicer,  the Certificate  Registrar and
     the Trustee may deal with the Clearing  Agency for all purposes  (including
     the making of distributions  on the Book-Entry  Certificates and the taking
     of actions by the Holders of  Book-Entry  Certificates)  as the  authorized
     representative of the Beneficial Owners;

          (iii)  to the  extent  that the  provisions  of this  Section  5.01(b)
     conflict with any other  provisions of this  Agreement,  the  provisions of
     this Section 5.01(b) shall control;

          (iv) the rights of Beneficial  Owners shall be exercised  only through
     the Clearing  Agency and shall be limited to those  established by law, the
     rules,  regulations  and  procedures of the Clearing  Agency and agreements
     between such Beneficial  Owners and the Clearing Agency and/or the Clearing
     Agency  Participants,  and all  references in this  Agreement to actions by
     Certificateholders  shall,  with  respect to the  Book-Entry  Certificates,
     refer to actions taken by the Clearing  Agency upon  instructions  from the
     Clearing  Agency  Participants,  and all  references  in this  Agreement to
     distributions, notices, reports and statements to Certificateholders shall,
     with  respect  to the  Book-Entry  Certificates,  refer  to  distributions,
     notices,  reports and statements to the Clearing Agency or its nominee,  as
     registered holder of the Book-Entry  Certificates,  as the case may be, for
     distribution to Beneficial  Owners in accordance with the procedures of the
     Clearing Agency; and

          (v) the initial  Clearing Agency will make book-entry  transfers among
     the Clearing Agency Participants and receive and transmit  distributions of
     principal  and  interest  on  the   Certificates  to  the  Clearing  Agency
     Participants,  for distribution by such Clearing Agency Participants to the
     Beneficial Owners or their nominees.

     For purposes of any  provision of this  Agreement  requiring or  permitting
actions  with the  consent of, or at the  direction  of,  Holders of  Book-Entry
Certificates  evidencing  specified Voting Interests,  such direction or consent
shall be given by  Beneficial  Owners  having the  requisite  Voting  Interests,
acting through the Clearing Agency.



<PAGE>



     Unless and until  Definitive  Certificates  have been issued to  Beneficial
Owners pursuant to Section 5.07, copies of the reports or statements referred to
in Section 4.04 shall be available to Beneficial  Owners upon written request to
the Trustee at the Corporate Trust Office.

Section 5.02.      Registration of Transfer and Exchange of Certificates.

     (a) The Trustee shall cause to be kept at one of the offices or agencies to
be maintained in  accordance  with the  provisions of Section 5.06 a Certificate
Register in which,  subject to such reasonable  regulations as it may prescribe,
the Trustee shall provide for the  registration of Certificates and of transfers
and exchanges of Certificates as herein  provided.  The Trustee shall act as, or
shall  appoint,   a  Certificate   Registrar  for  the  purpose  of  registering
Certificates and transfers and exchanges of Certificates as herein provided.

     Upon  surrender  for  registration  of transfer of any  Certificate  at any
office or agency  maintained  for such  purpose  pursuant  to Section  5.06 (and
subject to the provisions of this Section 5.02) the Trustee shall  execute,  and
shall date, authenticate (or cause the Authenticating Agent to authenticate) and
deliver,  in the name of the designated  transferee or transferees,  one or more
new Certificates of a like aggregate  principal  portion or Percentage  Interest
and of the same Class or Subclass.

     At the option of the Certificateholders,  Certificates may be exchanged for
other  Certificates of authorized  Denominations  of a like aggregate  principal
portion or Percentage  Interest and of the same Class or Subclass upon surrender
of the  Certificates to be exchanged at any such office or agency.  Whenever any
Certificates  are so surrendered  for exchange,  the Trustee shall execute,  and
shall date, authenticate (or cause the Authenticating Agent to authenticate) and
deliver,  the Certificates  which the  Certificateholder  making the exchange is
entitled to receive.  Every Certificate presented or surrendered for transfer or
exchange shall (if so required by the  Certificate  Registrar or the Trustee) be
duly endorsed by, or be accompanied by a written  instrument of transfer in form
satisfactory to the Certificate  Registrar,  duly executed by the Holder thereof
or his attorney duly authorized in writing.

     No  service   charge  shall  be  made  for  any  transfer  or  exchange  of
Certificates,  but the Trustee or 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 transfer or exchange of Certificates.

     All Certificates surrendered for transfer and exchange shall be canceled by
the Certificate Registrar, the Trustee or the Authenticating Agent in accordance
with their standard procedures.

     (b) No  transfer  of a  Class  A-7,  Class  B-3,  Class  B-4 or  Class  B-5
Certificate shall be made unless the registration requirements of the Securities
Act of 1933, as amended,  and any applicable  State securities laws are complied
with, or such transfer is exempt from the registration  requirements  under said
Act and laws. In the event that a transfer is to be made in



<PAGE>



reliance  upon an exemption  from said Act or laws,  (i) unless such transfer is
made in reliance on Rule 144A,  the Trustee or the Seller may, if such  transfer
is to be made within  three years after the later of (i) the date of the initial
sale of  Certificates or (ii) the last date on which the Seller or any affiliate
thereof was a Holder of the Certificates  proposed to be transferred,  require a
Class A-7,  Class  B-3,  Class B-4 or Class B-5  Certificateholder  to deliver a
written Opinion of Counsel acceptable to and in form and substance  satisfactory
to the  Trustee and the Seller,  to the effect  that such  transfer  may be made
pursuant to an  exemption,  describing  the  applicable  exemption and the basis
therefor, from said Act and laws or is being made pursuant to said Act and laws,
which Opinion of Counsel  shall not be an expense of the Trustee,  the Seller or
the Master  Servicer,  and (ii) the  Trustee  shall  require the  transferee  to
execute an investment  letter in the form of Exhibit J hereto  certifying to the
Seller and the Trustee the facts  surrounding  such transfer,  which  investment
letter  shall  not be an  expense  of the  Trustee,  the  Seller  or the  Master
Servicer.  The  Holder  of a Class  A-7,  Class  B-3,  Class  B-4 or  Class  B-5
Certificate  desiring to effect such transfer  shall,  and does hereby agree to,
indemnify  the  Trustee,  the Seller,  the Master  Servicer and any Paying Agent
acting on behalf of the  Trustee  against any  liability  that may result if the
transfer  is not so exempt or is not made in  accordance  with such  federal and
state  laws.  Neither  the Seller  nor the  Trustee  is under an  obligation  to
register the Class A-7,  Class B-3,  Class B-4 or Class B-5  Certificates  under
said Act or any other securities law.

     (c) No transfer of a Class A-PO (other than to an  affiliate  of the Seller
on the Closing  Date),  Class M or Class B Certificate  shall be made unless the
Trustee and the Seller shall have received (i) a representation  letter from the
transferee in the form of Exhibit J hereto,  in the case of a Class A-PO,  Class
B-3, Class B-4 or Class B-5 Certificate,  or in the form of Exhibit K hereto, in
the case of a Class M, Class B-1 or Class B-2  Certificate,  to the effect  that
either (a) such transferee is not an employee  benefit plan or other  retirement
arrangement  subject to Title I of ERISA or Code Section 4975, or a governmental
plan, as defined in Section 3(32) of ERISA, or subject to any federal,  state or
local law ("Similar Law") which is to a material extent similar to the foregoing
provisions  of ERISA or the Code  (collectively,  a "Plan")  and is not a person
acting on behalf of or using the assets of any such Plan,  which  representation
letter shall not be an expense of the Trustee, the Seller or the Master Servicer
or (b) with respect to the Class M, Class B-1 and Class B-2  Certificates  only,
if such transferee is an insurance company, the source of funds used to purchase
the Class M or Class B Certificate is an "insurance company general account" (as
such term is defined in Section V(e) of Prohibited  Transaction  Class Exemption
95-60 ("PTE  95-60"),  60 Fed. Reg.  35925 (July 12, 1995)) and there is no Plan
with  respect  to which  the  amount  of such  general  account's  reserves  and
liabilities for the contract(s)  held by or on behalf of such Plan and all other
Plans  maintained  by the same  employer  (or  affiliate  thereof  as defined in
Section V(a)(1) of PTE 95-60) or by the same employee  organization  exceeds 10%
of the total of all reserves and  liabilities  of such general  account (as such
amounts  are  determined  under  Section  I(a)  of PTE  95-60)  at the  date  of
acquisition  or (ii) in the  case of any  such  Class  A-PO,  Class M or Class B
Certificate  presented for  registration  in the name of a Plan, or a trustee of
any such Plan,  (A) an Opinion of Counsel  satisfactory  to the  Trustee and the
Seller to the effect that the purchase or holding of such Class A-PO, Class M or
Class B  Certificate  will not  result in the assets of the Trust  Estate  being
deemed to be "plan assets" and subject to the prohibited



transaction  provisions  of ERISA,  the Code or Similar Law and will not subject
the Trustee,  the Seller or the Master Servicer to any obligation in addition to
those  undertaken  in this  Agreement,  which Opinion of Counsel shall not be an
expense of the  Trustee,  the Seller or the Master  Servicer  and (B) such other
opinions of counsel,  officer's certificates and agreements as the Seller or the
Master Servicer may require in connection with such transfer,  which opinions of
counsel,  officers'  certificates  and agreements shall not be an expense of the
Trustee, the Seller or the Master Servicer.  The Class A-PO, Class M and Class B
Certificates  shall  bear  a  legend  referring  to the  foregoing  restrictions
contained in this paragraph.

     (d) No legal or beneficial  interest in all or any portion of the Class A-R
or Class  A-LR  Certificate  may be  transferred  directly  or  indirectly  to a
"disqualified  organization" within the meaning of Code Section 860E(e)(5) or an
agent  of  a  disqualified   organization   (including  a  broker,  nominee,  or
middleman),  to a Plan or a Person  investing the assets of a Plan (such plan or
Person,  an  "ERISA  Prohibited  Holder")  or  to  an  individual,  corporation,
partnership or other person unless such transferee (i) is not a Non-U.S.  Person
or (ii) is a Non-U.S.  Person that holds the Class A-R or Class A-LR Certificate
in connection  with the conduct of a trade or business  within the United States
and has  furnished  the  transferor  and the Trustee with an effective  Internal
Revenue  Service Form 4224 or (iii) is a Non-U.S.  Person that has  delivered to
both the  transferor  and the Trustee an opinion of a nationally  recognized tax
counsel  to the  effect  that  the  transfer  of the  Class  A-R or  Class  A-LR
Certificate  to it is in accordance  with the  requirements  of the Code and the
regulations  promulgated  thereunder  and that such transfer of the Class A-R or
Class A-LR  Certificate  will not be disregarded for federal income tax purposes
(any such  person who is not covered by clauses  (i),  (ii) or (iii) above being
referred to herein as a "Non-permitted  Foreign Holder"), and any such purported
transfer  shall be void and have no effect.  The Trustee shall not execute,  and
shall not authenticate (or cause the  Authenticating  Agent to authenticate) and
deliver,  a new Class A-R or Class A-LR  Certificate in connection with any such
transfer to a disqualified  organization  or agent thereof  (including a broker,
nominee or middleman),  an ERISA  Prohibited  Holder or a Non-permitted  Foreign
Holder,  and neither the  Certificate  Registrar  nor the Trustee shall accept a
surrender for transfer or registration of transfer, or register the transfer of,
the Class A-R or Class  A-LR  Certificate,  unless  the  transferor  shall  have
provided  to the Trustee an  affidavit,  substantially  in the form  attached as
Exhibit H hereto, signed by the transferee, to the effect that the transferee is
not such a disqualified organization,  an agent (including a broker, nominee, or
middleman)  for any  entity  as to  which  the  transferee  has not  received  a
substantially  similar affidavit,  an ERISA Prohibited Holder or a Non-permitted
Foreign  Holder,  which affidavit shall contain the consent of the transferee to
any such  amendments of this Agreement as may be required to further  effectuate
the  foregoing  restrictions  on  transfer  of  the  Class  A-R  or  Class  A-LR
Certificate  to  disqualified   organizations,   ERISA  Prohibited   Holders  or
Non-permitted  Foreign Holders.  Such affidavit shall also contain the statement
of the transferee  that (i) the transferee  has  historically  paid its debts as
they have  come due and  intends  to do so in the  future,  (ii) the  transferee
understands  that it may incur  liabilities in excess of cash flows generated by
the residual interest, (iii) the transferee intends to pay taxes associated with
holding the residual  interest as they become due and (iv) the  transferee  will
not transfer the Class A-R or Class A-LR  Certificate to any Person who does not
provide an affidavit substantially in the form attached as Exhibit H hereto.



<PAGE>



     The  affidavit  described in the  preceding  paragraph,  if not executed in
connection with the initial issuance of the Class A-R or Class A-LR Certificate,
shall be  accompanied  by a written  statement in the form attached as Exhibit I
hereto,  signed  by the  transferor,  to the  effect  that as of the time of the
transfer,  the  transferor  has no actual  knowledge  that the  transferee  is a
disqualified  organization,  ERISA Prohibited  Holder or  Non-permitted  Foreign
Holder,  and has no knowledge or reason to know that the statements  made by the
transferee  with  respect to clauses  (i) and (iii) of the last  sentence of the
preceding  paragraph  are not true.  The Class A-R and Class  A-LR  Certificates
shall bear a legend  referring to the foregoing  restrictions  contained in this
paragraph and the preceding paragraph.

     Upon notice to the Master Servicer that any legal or beneficial interest in
any  portion of the Class A-R or Class A-LR  Certificate  has been  transferred,
directly  or  indirectly,  to  a  disqualified  organization  or  agent  thereof
(including a broker,  nominee,  or middleman) in  contravention of the foregoing
restrictions, (i) such transferee shall be deemed to hold the Class A-R or Class
A-LR  Certificate in  constructive  trust for the last  transferor who was not a
disqualified  organization  or  agent  thereof,  and  such  transferor  shall be
restored as the owner of such Class A-R or Class A-LR  Certificate as completely
as if such transfer had never  occurred,  provided that the Master Servicer may,
but is not required to, recover any  distributions  made to such transferee with
respect to Class A-R or Class  A-LR  Certificate,  and (ii) the Master  Servicer
agrees to furnish to the Internal  Revenue  Service and to any transferor of the
Class A-R or Class A-LR Certificate or such agent (within 60 days of the request
therefor  by  the  transferor  or  agent)  such  information  necessary  to  the
application  of Code Section  860E(e) as may be required by the Code,  including
but not limited to the present value of the total anticipated  excess inclusions
with respect to the Class A-R or Class A-LR Certificate (or portion thereof) for
periods after such transfer. At the election of the Master Servicer, the cost to
the Master Servicer of computing and furnishing such  information may be charged
to the transferor or such agent referred to above;  however, the Master Servicer
shall in no event be excused from furnishing such information.

     (e) No transfer of a Class A-7 Certificate shall be made unless the Trustee
shall have received a  representation  letter in the form of Exhibit J hereto to
the effect that if the  transferee  is a Plan or a person acting on behalf of or
using the  assets of a Plan  such  transferee  is an  "accredited  investor"  as
defined in Rule  501(a)(1) of  Regulation D of the  Securities  Act of 1933,  as
amended, which representation letter shall not be an expense of the Trustee, the
Seller or the Master Servicer.

Section 5.03.      Mutilated, Destroyed, Lost or Stolen Certificates.

     If (i) any  mutilated  Certificate  is  surrendered  to the  Trustee or the
Authenticating  Agent,  or the  Trustee  or the  Authenticating  Agent  receives
evidence  to  its  satisfaction  of  the  destruction,  loss  or  theft  of  any
Certificate,  and (ii) there is delivered  to the Trustee or the  Authenticating
Agent such security or indemnity as may be required by them to hold each of them
harmless,  then,  in the absence of notice to the Trustee or the  Authenticating
Agent that such  Certificate  has been  acquired by a bona fide  purchaser,  the
Trustee shall execute and  authenticate  (or cause the  Authenticating  Agent to
authenticate) and deliver, in



<PAGE>



exchange  for or in lieu  of any  such  mutilated,  destroyed,  lost  or  stolen
Certificate, a new Certificate of like tenor and principal portion or Percentage
Interest  and of the  same  Class or  Subclass.  Upon  the  issuance  of any new
Certificate  under this Section,  the Trustee or the  Certificate  Registrar 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 expense  (including
the fees and expenses of the Trustee or the Authenticating  Agent) in connection
therewith.  Any  duplicate  Certificate  issued  pursuant to this Section  shall
constitute complete and indefeasible  evidence of ownership in the Trust Estate,
as if  originally  issued,  whether  or  not  the  lost,  stolen,  or  destroyed
Certificate shall be found at any time.

Section 5.04.      Persons Deemed Owners.

     Prior  to  the  due  presentation  of a  Certificate  for  registration  of
transfer,  the  Seller,  the  Master  Servicer,  the  Trustee,  the  Certificate
Registrar and any agent of the Seller,  the Master Servicer,  the Trustee or the
Certificate  Registrar  may treat the  Person in whose name any  Certificate  is
registered  as the  owner  of such  Certificate  for the  purpose  of  receiving
distributions  pursuant to Section 4.01, and for all other purposes  whatsoever,
and  neither the Seller,  the Master  Servicer,  the  Trustee,  the  Certificate
Registrar nor any agent of the Seller,  the Master Servicer,  the Trustee or the
Certificate Registrar shall be affected by notice to the contrary.

Section 5.05.      Access to List of Certificateholders' Names and Addresses.

     (a) If the Trustee is not acting as Certificate Registrar,  the Certificate
Registrar shall furnish or cause to be furnished to the Trustee,  within 15 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 or Subclass as of
the most recent Record Date.

     (b)  If  five  or  more  Certificateholders  (hereinafter  referred  to  as
"applicants") apply in writing to the Trustee,  and such application states that
the applicants desire to communicate with other  Certificateholders 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  following  the
receipt  of such  application,  afford  such  applicants  access  during  normal
business  hours  to the  most  recent  list  of  Certificateholders  held by the
Trustee. If such a list is as of the date more than 90 days prior to the date of
receipt of such  applicants'  request  and the  Trustee  is not the  Certificate
Registrar,  the Trustee shall promptly request from the Certificate  Registrar a
current  list as  provided  in  paragraph  (a)  hereof,  and shall  afford  such
applicants access to such list promptly upon receipt.

     (c) Every Certificateholder, by receiving and holding a Certificate, agrees
with the Seller, the Master Servicer,  the Certificate Registrar and the Trustee
that neither the Seller, the Master Servicer,  the Certificate Registrar nor the
Trustee  shall be held  accountable  by  reason  of the  disclosure  of any such
information as to the names, addresses and Percentage



<PAGE>



Interests of the  Certificateholders  hereunder,  regardless  of the source from
which such information was delivered.

Section 5.06.      Maintenance of Office or Agency.

     The  Trustee  will  maintain,  at its  expense,  an office or agency  where
Certificates  may be surrendered  for  registration  of transfer or exchange and
where notices and demands to or upon the Certificate Registrar in respect of the
Certificates and this Agreement may be served. The Trustee initially  designates
the  Corporate  Trust  Office and the  principal  corporate  trust office of the
Authenticating Agent, if any, as its offices and agencies for said purposes.

Section 5.07.      Definitive Certificates.

     If (i)(A) the  Master  Servicer  advises  the  Trustee in writing  that the
Clearing  Agency  is no  longer  willing  or  able  properly  to  discharge  its
responsibilities as depository with respect to the Book-Entry Certificates,  and
(B) the Master  Servicer  is unable to locate a  qualified  successor,  (ii) the
Master Servicer, 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 dismissal or resignation of the Master Servicer, Beneficial Owners
representing  aggregate  Voting  Interests of not less than 51% of the aggregate
Voting Interests of each outstanding Subclass of Book-Entry  Certificates advise
the Trustee  through the Clearing  Agency and 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 Beneficial  Owners,  the Trustee shall
notify the Beneficial Owners,  through the Clearing Agency, of the occurrence of
any such event and of the availability of Definitive  Certificates to Beneficial
Owners requesting the same. Upon surrender to the Trustee by the Clearing Agency
of the Certificates held of record by its nominee, accompanied by reregistration
instructions and directions to execute and  authenticate  new Certificates  from
the Master  Servicer,  the Trustee  shall  execute and  authenticate  Definitive
Certificates  for delivery at its Corporate  Trust Office.  The Master  Servicer
shall arrange for, and will bear all costs of, the printing and issuance of such
Definitive Certificates. Neither the Seller, the Master Servicer nor the Trustee
shall be liable for any delay in delivery of such  instructions  by the Clearing
Agency and may conclusively  rely on, and shall be protected in relying on, such
instructions.

Section 5.08.      Notices to Clearing Agency.

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

     Neither the Seller nor the Master Servicer nor any subcontractor nor any of

Person  against  any breach of  warranties  or  representations  made  herein or
against  any  liability  which would  otherwise  be imposed by reason of willful
misfeasance,  bad faith or gross  negligence in the  performance of duties or by
reason of reckless  disregard of obligations and duties  hereunder.  The Seller,
the Master Servicer,  any  subcontractor,  and any partner,  director,  officer,
employee  or agent of any of them shall be entitled  to  indemnification  by the
Trust Estate and will be held  harmless  against any loss,  liability or expense
incurred in connection  with any legal action  relating to this Agreement or the
Certificates,  other than any loss,  liability or expense  incurred by reason of
willful misfeasance, bad faith or gross



<PAGE>



negligence  in the  performance  of his or its duties  hereunder or by reason of
reckless  disregard of his or its obligations and duties hereunder.  The Seller,
the Master Servicer and any of the directors,  officers,  employees or agents of
either may rely in good faith on any document of any kind which, prima facie, is
properly  executed and submitted by any Person  respecting  any matters  arising
hereunder.  Neither  the  Seller  nor the  Master  Servicer  shall be under  any
obligation to appear in, prosecute or defend any legal action unless such action
is related  to its  respective  duties  under  this  Agreement  and which in its
opinion does not involve it in any expense or liability; provided, however, that
the Seller or the  Master  Servicer  may in its  discretion  undertake  any such
action which it may deem  necessary or desirable  with respect to this Agreement
and the  rights  and  duties of the  parties  hereto  and the  interests  of the
Certificateholders  hereunder if the  Certificateholders  offer to the Seller or
the  Master  Servicer,  as the case may be,  reasonable  security  or  indemnity
against the costs,  expenses and  liabilities  which may be incurred  therein or
thereby.  In such  event,  the legal  expenses  and costs of such action and any
liability  resulting  therefrom shall be expenses,  costs and liabilities of the
Trust  Estate,  and the Seller or the Master  Servicer  shall be  entitled to be
reimbursed therefor out of the Certificate  Account,  and such amounts shall, on
the following Distribution Date or Distribution Dates, be allocated in reduction
of  distributions  on the Class A, Class M and Class B Certificates  in the same
manner as Realized Losses are allocated pursuant to Section 4.02(a).

Section 6.04.      Resignation of the Master Servicer.

     The Master Servicer shall not resign from the obligations and duties hereby
imposed on it except upon  determination that its duties hereunder are no longer
permissible  under  applicable  law or are in  material  conflict  by  reason of
applicable  law  with  any  other   activities   carried  on  by  it.  Any  such
determination  permitting  the  resignation  of the  Master  Servicer  shall  be
evidenced by an Opinion of Counsel to such effect  delivered to the Trustee.  No
such  resignation  shall  become  effective  until the  Trustee  or a  successor
servicer  shall have  assumed the Master  Servicer's  responsibilities,  duties,
liabilities and obligations hereunder.

Section 6.05.      Compensation to the Master Servicer.

     The Master Servicer shall be entitled to receive a monthly fee equal to the
Master  Servicing  Fee,  as  compensation  for  services  rendered by the Master
Servicer under this Agreement.  The Master Servicer also will be entitled to any
late reporting fees paid by a Servicer  pursuant to its Servicing  Agreement and
any  investment  income  on funds  on  deposit  in the  Certificate  Account  as
additional compensation.

Section 6.06.      Assignment or Delegation of Duties by Master Servicer.

     The  Master  Servicer  shall not  assign  or  transfer  any of its  rights,
benefits or privileges under this Agreement to any other Person,  or delegate to
or subcontract  with, or authorize or appoint any other Person to perform any of
the duties,  covenants or  obligations  to be  performed by the Master  Servicer
without the prior written  consent of the Trustee and any agreement,  instrument
or act purporting to effect any such assignment, transfer, delegation or



<PAGE>



appointment shall be void.  Notwithstanding  the foregoing,  the Master Servicer
shall have the right  without  the prior  written  consent of the Trustee (i) to
assign its rights and delegate its duties and obligations  hereunder;  provided,
however,  that (a) the  purchaser or  transferee  accepting  such  assignment or
delegation  is  qualified  to  service  mortgage  loans  for FNMA or  FHLMC,  is
satisfactory  to the Trustee,  in the exercise of its reasonable  judgment,  and
executes  and  delivers  to the  Trustee  an  agreement,  in form and  substance
reasonably  satisfactory  to the Trustee,  which  contains an assumption by such
purchaser or transferee of the due and punctual  performance  and  observance of
each covenant and  condition to be performed or observed by the Master  Servicer
hereunder  from and after the date of such  agreement;  and (b) each  applicable
Rating Agency's rating of any Certificates in effect  immediately  prior to such
assignment,  sale  or  transfer  is  not  reasonably  likely  to  be  qualified,
downgraded or withdrawn as a result of such assignment, sale or transfer and the
Certificates  are not reasonably  likely to be placed on credit review status by
any such Rating Agency; and (ii) to delegate to, subcontract with, authorize, or
appoint an affiliate of the Master Servicer to perform and carry out any duties,
covenants or obligations to be performed and carried out by the Master  Servicer
under this Agreement and hereby agrees so to delegate, subcontract, authorize or
appoint  to an  affiliate  of the  Master  Servicer  any  duties,  covenants  or
obligations to be performed and carried out by the Master Servicer to the extent
that such duties,  covenants or obligations  are to be performed in any state or
states in which the  Master  Servicer  is not  authorized  to do  business  as a
foreign  corporation  but in which the affiliate is so  authorized.  In no case,
however,  shall any  permitted  assignment  and  delegation  relieve  the Master
Servicer of any  liability  to the Trustee or the Seller  under this  Agreement,
incurred  by it prior to the time that the  conditions  contained  in clause (i)
above are met.

Section 6.07.      Indemnification of Trustee and Seller by Master Servicer.

     The Master  Servicer shall  indemnify and hold harmless the Trustee and the
Seller and any director, officer or agent thereof against any loss, liability or
expense,  including  reasonable  attorney's fees,  arising out of, in connection
with or incurred by reason of willful  misfeasance,  bad faith or  negligence in
the  performance  of duties of the Master  Servicer  under this  Agreement or by
reason of reckless disregard of its obligations and duties under this Agreement.
Any payment  pursuant to this Section made by the Master Servicer to the Trustee
or the  Seller  shall be from such  entity's  own funds,  without  reimbursement
therefor.  The provisions of this Section 6.07 shall survive the  termination of
this Agreement.

     upon  which  written  notice  of such  failure,  requiring  the  same to be
     remedied, shall have been given to the Master Servicer by the Trustee or to
     the  Master  Servicer  and  the  Trustee  by the  holders  of  Certificates
     evidencing  in the  aggregate  not less  than 25% of the  aggregate  Voting
     Interest represented by all Certificates; or

          (ii) any failure on the part of the Master Servicer duly to observe or
     perform in any material respect any other of the covenants or agreements on
     the part of the Master  Servicer in the  Certificates  or in this Agreement
     which continues  unremedied for a period of 60 days after the date on which
     written  notice of such failure,  requiring the same to be remedied,  shall
     have been given to the Master  Servicer  by the  Trustee,  or to the Master
     Servicer and the Trustee by the holders of  Certificates  evidencing in the
     aggregate not less than 25% of the aggregate Voting Interest represented by
     all Certificates; or

          (iii) a decree or order of a court or agency or supervisory  authority
     having  jurisdiction  in the  premises  for the  appointment  of a trustee,
     conservator,   receiver  or  liquidator  in  any  bankruptcy,   insolvency,
     readjustment  of debt,  marshaling  of assets  and  liabilities  or similar
     proceedings,  or for the winding-up or  liquidation  of its affairs,  shall
     have been  entered  against  the Master  Servicer  and such decree or order
     shall have remained in force  undischarged  and unstayed for a period of 60
     days; or

          (iv)  the  Master  Servicer  shall  consent  to the  appointment  of a

     any bankruptcy, insolvency,  readjustment of debt, marshaling of assets and
     liabilities, voluntary liquidation or similar proceedings of or relating to
     the Master Servicer,  or of or relating to all or substantially  all of its
     property; or

          (v) the Master  Servicer  shall admit in writing its  inability to pay
     its debts  generally as they become due, file a petition to take  advantage
     of any applicable



<PAGE>



     insolvency,  bankruptcy or reorganization  statute,  make an assignment for
     the  benefit  of  its  creditors  or  voluntarily  suspend  payment  of its
     obligations;

          (vi) the Master  Servicer shall be dissolved,  or shall dispose of all
     or  substantially  all of its  assets;  or  consolidate  with or merge into
     another  entity or shall permit another entity to consolidate or merge into
     it,  such  that the  resulting  entity  does not  meet the  criteria  for a
     successor servicer, as specified in Section 6.02 hereof; or

          (vii) the Master Servicer and any subservicer  appointed by it becomes
     ineligible  to  service  for  both  FNMA  and  FHMLC,  which  ineligibility
     continues unremedied for a period of 90 days.



then, and in each and every such case,  subject to applicable law, so long as an
Event of Default shall not have been remedied, either the Trustee or the holders
of  Certificates  evidencing  in the  aggregate  not  less  than  66 2/3% of the
aggregate Voting Interest represented by all Certificates,  by notice in writing
to the Master  Servicer (and to the Trustee if given by the  Certificateholders)
may terminate all of the rights and  obligations  of the Master  Servicer  under
this Agreement and in and to the Mortgage  Loans,  but without  prejudice to any
rights which the Master Servicer may have to the aggregate Master Servicing Fees
due prior to the date of  transfer  of the  Master  Servicer's  responsibilities
hereunder,  reimbursement of expenses to the extent permitted by this Agreement,
Periodic  Advances  and other  advances  of its own funds.  Upon  receipt by the
Master  Servicer of such written  notice,  all authority and power of the Master
Servicer under this Agreement,  whether with respect to the  Certificates or the
Mortgage Loans or otherwise, shall pass to and be vested in the Trustee pursuant
to and under this  Section,  subject to the  provisions  of Section  7.05;  and,
without  limitation,  the Trustee is hereby  authorized and empowered to execute
and deliver, on behalf of the Master Servicer, as attorney-in-fact or otherwise,
any and all documents and other  instruments,  and to do or accomplish all other
acts or things necessary or appropriate to effect the purposes of such notice of
termination,  whether to complete the transfer and  endorsement or assignment of
the Mortgage  Loans and related  documents  or  otherwise.  The Master  Servicer
agrees to cooperate with the Trustee in effecting the  termination of the Master
Servicer's  responsibilities and rights hereunder and shall promptly provide the
Trustee all  documents  and records  reasonably  requested by it to enable it to
assume  the  Master  Servicer's  functions  hereunder  and shall  promptly  also
transfer to the  Trustee  all  amounts  which then have been or should have been
deposited  in the  Certificate  Account  by the  Master  Servicer  or which  are
thereafter received by the Master Servicer with respect to the Mortgage Loans.

Section 7.02.      Other Remedies of Trustee.

     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 7.01,  shall have the right,  in its own name 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



<PAGE>



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 filing 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 7.03.      Directions by Certificateholders and
Duties of Trustee During Event of Default.

     During the  continuance  of any Event of Default,  Holders of  Certificates
evidencing in the aggregate not less than 25% of the aggregate  Voting  Interest
represented  by all  Certificates  may  direct  the  time,  method  and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee,  under this Agreement;  provided,
however,  that the  Trustee  shall be under no  obligation  to  pursue  any such
remedy,  or to  exercise  any of the  trusts  or  powers  vested  in it by  this
agreement (including, without limitation, (i) the conducting or defending of any
administrative action or litigation hereunder or in relation hereto and (ii) the
terminating  of the Master  Servicer  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 nonassenting Certificateholders.

Section 7.04.      Action upon Certain Failures of the
Master Servicer and upon Event of Default.

     In the event that the Trustee  shall have  knowledge  of any failure of the
Master Servicer specified in Section 7.01(i) or (ii) which would become an Event
of Default upon the Master  Servicer's  failure to remedy the same after notice,
the  Trustee   may,   but  need  not  if  the  Trustee   deems  it  not  in  the
Certificateholders'  best interest,  give notice thereof to the Master Servicer.
For all  purposes of this  Agreement,  in the absence of actual  knowledge  by a
corporate  trust  officer of the Trustee or the  Trustee  shall not be deemed to
have  knowledge  of any failure of the Master  Servicer as  specified in Section
7.01(i) and (ii) or any Event of Default unless  notified  thereof in writing by
the Master Servicer or by a Certificateholder.

Section 7.05.      Trustee to Act; Appointment of Successor.

     When the Master Servicer receives notice of termination pursuant to Section
7.01 or the Trustee receives the resignation of the Master Servicer evidenced by
an Opinion of



<PAGE>



     Counsel pursuant to Section 6.04, the Trustee shall be the successor in all
respects to the Master  Servicer in its capacity as master  servicer  under this
Agreement and the  transactions  set forth or provided for herein and shall have
the rights and  powers  and be subject to all the  responsibilities,  duties and
liabilities  relating  thereto  placed on the Master  Servicer  by the terms and
provisions  hereof and in its  capacity  as such  successor  shall have the same
limitation of liability herein granted to the Master Servicer. In the event that
the Trustee is  succeeding  to the Master  Servicer as the Master  Servicer,  as
compensation  therefor,  the Trustee  shall be entitled to receive  monthly such
portion  of the  Master  Servicing  Fee,  together  with  such  other  servicing
compensation  as is  agreed  to at such  time  by the  Trustee  and  the  Master
Servicer,  but in no  event  more  than  25%  thereof  until  the  date of final
cessation   of   the   Master   Servicer's   servicing   activities   hereunder.
Notwithstanding  the above, the Trustee may, if it shall be unwilling to so act,
or shall,  if it is unable to so act or to obtain a qualifying  bid as described
below,  appoint, or petition a court of competent  jurisdiction to appoint,  any
housing and home finance  institution,  bank or mortgage  servicing  institution
having a net worth of not less than $10,000,000 and meeting such other standards
for a successor servicer as are set forth herein, as the successor to the Master
Servicer hereunder in the assumption of all or any part of the responsibilities,
duties or liabilities of the Master Servicer hereunder;  provided, however, that
until  such a  successor  master  servicer  is  appointed  and has  assumed  the
responsibilities,  duties and liabilities of the Master Servicer hereunder,  the
Trustee  shall  continue  as the  successor  to the Master  Servicer as provided
above.  The compensation of any successor master servicer so appointed shall not
exceed the  compensation  specified  in Section  6.05  hereof.  In the event the
Trustee is  required  to solicit  bids as  provided  above,  the  Trustee  shall
solicit,   by  public   announcement,   bids  from   housing  and  home  finance
institutions,   banks  and   mortgage   servicing   institutions   meeting   the
qualifications  set forth in the  preceding  sentence  for the  purchase  of the
master  servicing  functions.  Such public  announcement  shall specify that the
successor  master  servicer  shall be  entitled to the full amount of the Master
Servicing Fee as compensation together with the other servicing  compensation in
the form of late reporting fees or otherwise as provided in Section 6.05. Within
30 days after any such public  announcement,  the Trustee  shall  negotiate  and
effect the sale,  transfer and  assignment  of the master  servicing  rights and
responsibilities  hereunder  to  the  qualified  party  submitting  the  highest
qualifying  bid.  The Trustee  shall deduct all costs and expenses of any public
announcement  and of any sale,  transfer and assignment of the servicing  rights
and  responsibilities  hereunder  from any sum  received by the Trustee from the
successor  to the  Master  Servicer  in  respect  of  such  sale,  transfer  and
assignment.  After such  deductions,  the remainder of such sum shall be paid by
the  Trustee  to the Master  Servicer  at the time of such  sale,  transfer  and
assignment to the Master  Servicer's  successor.  The Trustee and such successor
shall take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession. The Master Servicer agrees to cooperate with the
Trustee and any successor  servicer in effecting the  termination  of the Master
Servicer's  servicing  responsibilities  and rights hereunder and shall promptly
provide  the Trustee or such  successor  master  servicer,  as  applicable,  all
documents  and  records  reasonably  requested  by it to enable it to assume the
Master  Servicer's  function  hereunder and shall  promptly also transfer to the
Trustee or such successor master servicer, as applicable, all amounts which then
have been or should have been deposited in the Certificate Account by the Master
Servicer or which are thereafter received by the Master Servicer with respect to
the Mortgage Loans. Neither the Trustee nor any other successor master servicer



<PAGE>



shall be deemed to be in default  hereunder by reason of any failure to make, or
any delay in making, any distribution hereunder or any portion thereof caused by
(i) the failure of the Master  Servicer to deliver,  or any delay in delivering,
cash, documents or records to it, or (ii) restrictions imposed by any regulatory
authority having jurisdiction over the Master Servicer. Notwithstanding anything
to the contrary contained in Section 7.01 above or this Section 7.05, the Master
Servicer shall retain all of its rights and responsibilities  hereunder,  and no
successor  (including  the Trustee)  shall succeed  thereto,  if the  assumption
thereof by such successor would cause the rating assigned to any Certificates to
be  revoked,  downgraded  or placed  on credit  review  status  (other  than for
possible  upgrading) by either  Rating  Agency and the retention  thereof by the
Master Servicer would avert such revocation, downgrading or review.

Section 7.06.      Notification to Certificateholders.

     Upon any  termination of the Master  Servicer or appointment of a successor
master servicer,  in each case as provided herein, the Trustee shall give prompt
written  notice  thereof to  Certificateholders  at their  respective  addresses
appearing in 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 at their respective addresses appearing in
the Certificate Register,  unless such Event of Default shall have been cured or
waived within said 45 day period.

ARTICLE VIII

CONCERNING THE TRUSTEE

Section 8.01.      Duties of Trustee.

     The Trustee,  prior to the  occurrence of an Event of Default and after the
curing of all Events of Default which may have  occurred,  undertakes to perform
such  duties  and  only  such  duties  as are  specifically  set  forth  in this
Agreement.  In case an Event of Default has occurred (which has not been cured),
the Trustee,  subject to the provisions of Sections 7.01,  7.03,  7.04 and 7.05,
shall exercise such of the rights and powers vested in it by this Agreement, and
use the same  degree of care and  skill in its  exercise  as a prudent  investor
would exercise or use under the  circumstances in the conduct of such investor's
own affairs.

     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  certificate,  statement,
instrument,  report,  notice or other document furnished by the Master Servicer,
any Paying Agent that is not the Trustee or the  Servicers  pursuant to Articles
III, IV and IX.

     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)  Prior to the  occurrence  of an Event of  Default  and  after the
     curing of all such Events of Default  which may have  occurred,  the duties
     and  obligations  of the Trustee shall be determined  solely by the express
     provisions  of this  Agreement,  the Trustee shall not be liable except for
     the  performance  of such duties and  obligations as are  specifically  set
     forth in this Agreement,  no implied covenants or obligations shall be read
     into this Agreement against the Trustee and, in the absence of bad faith on
     the part of the Trustee, the Trustee may conclusively rely, as to the truth
     of the statements and the  correctness of the opinions  expressed  therein,
     upon any certificates or opinions furnished to the Trustee,  and conforming
     to the requirements of this Agreement;

          (ii) 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  which evidence in
     the aggregate not less than 25% of the Voting  Interest  represented by all
     Certificates  relating  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; and



<PAGE>



          (iii) The Trustee  shall not be liable for any error of judgment  made
     in good faith by any of their respective  Responsible  Officers,  unless it
     shall be proved that the Trustee or such Responsible  Officer,  as the case
     may be, was negligent in ascertaining the pertinent facts.

     None of the  provisions  contained  in this  Agreement  shall  require  the
Trustee to expend or risk its own funds or otherwise  incur  personal  financial
liability in the  performance of any of its duties  hereunder or in the exercise
of any of its rights or powers if there is reasonable  ground for believing that
repayment of such funds or adequate  indemnity against such risk or liability is
not reasonably assured to it.

Section 8.02.      Certain Matters Affecting the Trustee.

     Except as otherwise provided in Section 8.01:

          (i) The  Trustee  may  rely  and  shall  be  protected  in  acting  or
     refraining  from  acting  upon  any  resolution,   Officers'   Certificate,
     certificate of auditors or any other  certificate,  statement,  instrument,
     opinion, report, notice, request,  consent, order, appraisal, 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 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 Opinion of Counsel;

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

          (iv) 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.

Section 8.03.      Trustee not Required to Make Investigation.

     Prior to the  occurrence  of an Event of  Default  hereunder  and after the
curing of all Events of Default which may have  occurred,  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, appraisal, bond, Mortgage, Mortgage Note or other paper
or document (provided the same appears regular on its face), unless requested in
writing to do so by holders of Certificates evidencing in the aggregate not less
than 51% of the  Voting  Interest  represented  by all  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 as a
condition to



<PAGE>



so proceeding.  The reasonable expense of every such investigation shall be paid
by the Master Servicer or, if paid by the Trustee, shall be repaid by the Master
Servicer upon demand.

Section 8.04.      Trustee not Liable for Certificates or Mortgage Loans.

     The  recitals  contained  herein and in the  Certificates  (other  than the
certificate  of  authentication  on the  Certificates)  shall  be  taken  as the
statements of the Seller,  and the Trustee assumes no  responsibility  as to the
correctness of the same. The Trustee makes no representation for the correctness
of  the  same.  The  Trustee  makes  no  representation  as to the  validity  or
sufficiency of this Agreement or of the  Certificates or of any Mortgage Loan or
related document.  Subject to Section 2.04, the Trustee shall not be accountable
for the use or  application by the Seller of any of the  Certificates  or of the
proceeds of such  Certificates,  or for the use or application of any funds paid
to the Master  Servicer  in respect of the  Mortgage  Loans  deposited  into the
Certificate  Account by the Master Servicer or, in its capacity as trustee,  for
investment of any such amounts.

Section 8.05.      Trustee May Own Certificates.

     The Trustee and any agent thereof, in its individual or any other capacity,
may become the owner or pledgee of  Certificates  with the same  rights it would
have if it were not Trustee or such agent.

Section 8.06.      The Master Servicer to Pay Fees and Expenses.

     The Master Servicer covenants and agrees to pay to the Trustee from time to
time,  and the Trustee  shall be entitled  to receive,  reasonable  compensation
(which  shall  not  be  limited  by  any  provision  of  law  in  regard  to the
compensation  of a trustee of an express trust) for all services  rendered by it
in  the  execution  of the  trusts  hereby  created  and  in  the  exercise  and
performance  of any of the powers and duties  hereunder of the Trustee,  and the
Master  Servicer  will pay or  reimburse  the  Trustee  upon its request for all
reasonable  expenses,  disbursements  and  advances  incurred  or  made by it in
accordance  with  any  of  the  provisions  of  this  Agreement  (including  the
reasonable compensation and the expenses and disbursements of its counsel and of
all persons not regularly in its employ) except any such expense,  disbursement,
or advance as may arise from its negligence or bad faith.

Section 8.07.      Eligibility Requirements.

     The  Trustee  hereunder  shall  at  all  times  (i)  be  a  corporation  or
association  having its principal  office in a state and city  acceptable to the
Seller,  organized and doing business under the laws of such state or the United
States of  America,  authorized  under  such laws to  exercise  corporate  trust
powers, having a combined capital and surplus of at least $50,000,000,  or shall
be a member of a bank holding system, the aggregate combined capital and surplus
of which is at least $50,000,000, provided that its separate capital and surplus
shall at all times be at least the amount specified in Section  310(a)(2) of the
Trust  Indenture Act of 1939,  (ii) be subject to  supervision or examination by
federal or state authority and (iii) have a



<PAGE>



credit  rating or be  otherwise  acceptable  to the  Rating  Agencies  such that
neither of the Rating  Agencies  would  reduce  their  respective  then  current
ratings of the Certificates (or have provided such security from time to time as
is  sufficient  to avoid such  reduction) as evidenced in writing by each Rating
Agency.  If such  corporation or 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 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 the  provisions of this Section,  such entity shall
resign immediately in the manner and with the effect specified in Section 8.08.

Section 8.08.      Resignation and Removal.

     The Trustee may at any time resign and be discharged  from the trust hereby
created by giving written notice of  resignation  to the Master  Servicer,  such
resignation to be effective upon the  appointment of a successor  trustee.  Upon
receiving such notice of resignation, the Master Servicer shall promptly appoint
a  successor  trustee by written  instrument,  in  duplicate,  one copy of which
instrument  shall  be  delivered  to the  resigning  entity  and one copy to its
successor.  If no successor  trustee shall have been appointed and 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.

     If at any time the Trustee  shall cease to be eligible in  accordance  with
the  provisions of Section 8.07 and shall fail to resign after  written  request
for its resignation by the Master Servicer,  or if at any time the Trustee shall
become  incapable  of acting,  or an order for relief shall have been entered in
any  bankruptcy  or  insolvency  proceeding  with respect to such  entity,  or a
receiver of such entity or of its  property  shall be  appointed,  or any public
officer  shall  take  charge or control of the  Trustee  or of the  property  or
affairs  of the  Trustee  for  the  purpose  of  rehabilitation,  conversion  or
liquidation,  or the Master  Servicer shall deem it necessary in order to change
the situs of the Trust  Estate for state tax reasons,  then the Master  Servicer
shall remove the Trustee and appoint a successor trustee by written  instrument,
in duplicate,  one copy of which instrument shall be delivered to the Trustee so
removed and one copy to the successor trustee.

     The Holders of  Certificates  evidencing in the aggregate not less than 51%
of the  Voting  Interests  represented  by all  Certificates  (except  that  any
Certificate  registered  in the name of the Seller,  the Master  Servicer or any
affiliate  thereof  will not be taken into  account in  determining  whether the
requisite Voting Interests has been obtained) may at any time remove the Trustee
and appoint a successor by written  instrument or  instruments,  in  triplicate,
signed by such holders or their attorneys-in-fact duly authorized,  one complete
set of which instruments shall be delivered to the Master Servicer, one complete
set of which  shall be  delivered  to the entity or  entities so removed and one
complete set of which shall be delivered to the successor so appointed.



<PAGE>



     Any  resignation  or removal of the Trustee and  appointment of a successor
pursuant to any of the  provisions of this Section shall become  effective  upon
acceptance of appointment by the successor as provided in Section 8.09.

Section 8.09.      Successor.

     Any successor  trustee appointed as provided in Section 8.08 shall execute,
acknowledge and deliver to the Master Servicer and to its predecessor trustee an
instrument accepting such appointment  hereunder,  and thereupon the resignation
or  removal  of  the  predecessor  trustee  shall  become  effective,  and  such
successor,  without any further act,  deed or  reconveyance,  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 its successor all Owner Mortgage Loan Files
and related  documents and statements held by it hereunder (other than any Owner
Mortgage  Loan  Files at the time held by a  Custodian,  which  Custodian  shall
become the agent of any successor trustee hereunder), and the Seller, the Master
Servicer and the predecessor  entity shall execute and deliver such  instruments
and do such  other  things as may  reasonably  be  required  for more  fully and
certainly  vesting and  confirming  in the  successor  trustee all such  rights,
powers,  duties and  obligations.  No  successor  shall  accept  appointment  as
provided in this Section  unless at the time of such  acceptance  such successor
shall be eligible under the provisions of Section 8.07

     Upon  acceptance of appointment by a successor as provided in this Section,
the  Master  Servicer  shall  mail  notice  of the  succession  of such  trustee
hereunder  to all Holders of  Certificates  at their  addresses  as shown in the
Certificate  Register.  If the Master  Servicer fails to mail such notice within
ten days after acceptance of the successor trustee,  the successor trustee shall
cause such notice to be mailed at the expense of the Master Servicer.

Section 8.10.      Merger or Consolidation.

     Any Person into which the Trustee may be merged or  converted or with which
it may be  consolidated,  to which it may sell or transfer its  corporate  trust
business  and  assets  as a whole  or  substantially  as a whole  or any  Person
resulting from any merger, sale, transfer,  conversion or consolidation to which
the Trustee shall be a party,  or any Person  succeeding to the business of such
entity, shall be the successor of the Trustee hereunder; provided, however, that
(i) such Person shall be eligible under the provisions of Section 8.07,  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,  and (ii)
the  Trustee  shall  deliver  an Opinion of Counsel to the Seller and the Master
Servicer to the effect that such merger,  consolidation,  sale or transfer  will
not subject  either the  Upper-Tier  REMIC or the  Lower-Tier  REMIC to federal,
state or local tax or cause either the Upper-Tier  REMIC or the Lower-Tier REMIC
to fail to qualify  as a REMIC,  which  Opinion of Counsel  shall be at the sole
expense of the Trustee.



<PAGE>



Section 8.11.      Authenticating Agent.

     The Trustee may appoint an Authenticating  Agent, 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  countersignature,  such  reference  shall be deemed to
include  authentication on behalf of the Trustee by the Authenticating Agent and
a  certificate  of  authentication  executed  on  behalf of the  Trustee  by the
Authenticating  Agent. The Authenticating Agent must be acceptable to the Seller
and the Master  Servicer and must be a corporation  organized and doing business
under  the laws of the  United  States  of  America  or of any  state,  having a
principal  office and place of  business in a state and city  acceptable  to the
Seller and the Master  Servicer,  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.

     Any  corporation  into  which  the  Authenticating  Agent  may be merged or
converted or with which it may be  consolidated,  or any  corporation  resulting
from any merger,  conversion or consolidation to which the Authenticating  Agent
shall be a party, or any corporation succeeding to the corporate agency business
of the  Authenticating  Agent,  shall 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.

     The Authenticating Agent may at any time resign by giving at least 30 days'
advance written notice of resignation to the Trustee,  the Seller and the Master
Servicer. The Trustee may at any time terminate the agency of the Authenticating
Agent by giving written notice thereof to the  Authenticating  Agent, the Seller
and the Master  Servicer.  Upon receiving a notice of resignation or upon such a
termination,  or in case at any time the Authenticating  Agent shall cease to be
eligible in accordance  with the  provisions  of this Section 8.11,  the Trustee
promptly  shall  appoint  a  successor  Authenticating  Agent,  which  shall  be
acceptable  to the  Master  Servicer,  and  shall  give  written  notice of such
appointment  to the  Seller,  and shall mail notice of such  appointment  to all
Certificateholders.  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 herein.  No successor  Authenticating
Agent shall be appointed  unless  eligible  under the provisions of this Section
8.11.

     The Authenticating  Agent shall have no responsibility or liability for any
action  taken by it as such at the  direction  of the  Trustee.  Any  reasonable
compensation paid to the  Authenticating  Agent shall be a reimbursable  expense
under Section 8.06.

Section 8.12.      Separate Trustees and Co-Trustees.

     The  Trustee  shall have the power from time to time to appoint one or more
persons or corporations  to act either as co-trustees  jointly with the Trustee,
or as separate  trustees,  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,



<PAGE>



where such  separate  trustee or  co-trustee  is necessary or advisable  (or the
Trustee  is  advised  by the  Master  Servicer  that such  separate  trustee  or
co-trustee  is  necessary or  advisable)  under the laws of any state in which a
Mortgaged Property is located or for the purpose of otherwise  conforming to any
legal  requirement,  restriction  or condition in any state in which a Mortgaged
Property is located or in any state in which any portion of the Trust  Estate is
located.  The Master  Servicer  shall advise the Trustee when, in its good faith
opinion,  a  separate  trustee  or  co-trustee  is  necessary  or  advisable  as
aforesaid.  The separate  trustees or co-trustees so appointed shall be trustees
for the  benefit of all of 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 Seller and the Master
Servicer  shall  join in any such  appointment,  but such  joining  shall not be
necessary for the effectiveness of such appointment.

     Every separate  trustee and co-trustee  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  or  co-trustee
     jointly,  except to the extent  that under any law of any  jurisdiction  in
     which any  particular  act or acts are to be performed  (whether as Trustee
     hereunder  or as successor to the Master  Servicer  hereunder)  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 Estate or any portion thereof in any such  jurisdiction)
     shall be exercised and performed by such separate trustee or co-trustee;

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

          (iv) the Trustee may at any time accept the  resignation  of or remove
     any separate  trustee or co-trustee so appointed by it, if such resignation
     or removal does not violate the other terms of this Agreement.

     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.  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



<PAGE>



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 furnished to the Trustee.

     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  or
co-trustee 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.

     No separate  trustee or co-trustee  hereunder shall be required to meet the
terms of eligibility as a successor  trustee under Section 8.07 hereunder and no
notice to  Certificateholders of the appointment thereof shall be required under
Section 8.09 hereof.

     The  Trustee  agrees to  instruct  its  co-trustees,  if any, to the extent
necessary to fulfill such entity's obligations hereunder.

     The  Master   Servicer  shall  pay  the  reasonable   compensation  of  the
co-trustees to the extent,  and in accordance  with the standards,  specified in
Section 8.06 hereof.

Section 8.13.      Appointment of Custodians.

     The Trustee may at any time on or after the Closing Date,  with the consent
of the Master  Servicer and the Seller,  appoint one or more  Custodians to hold
all or a portion of the Owner  Mortgage Loan Files as agent for the Trustee,  by
entering into a Custodial  Agreement.  Subject to this Article VIII, the Trustee
agrees to comply with the terms of each  Custodial  Agreement and to enforce the
terms and  provisions  thereof  against  the  Custodian  for the  benefit of the
Certificateholders.  Each Custodian shall be a depository institution subject to
supervision  by federal or state  authority,  shall have a combined  capital and
surplus of at least  $10,000,000  and shall be  qualified  to do business in the
jurisdiction  in which it holds any Owner  Mortgage  Loan File.  Each  Custodial
Agreement may be amended only as provided in Section 10.01(a).

Section 8.14.      Tax Matters; Compliance with REMIC Provisions.

     (a) Each of the Trustee and the Master  Servicer  covenants and agrees that
it shall  perform its duties  hereunder  in a manner  consistent  with the REMIC
Provisions  and shall not  knowingly  take any action or fail to take any action
that would (i)  affect the  determination  of the Trust  Estate's  status as two
separate  REMICs;  or (ii) cause the  imposition of any federal,  state or local
income,  prohibited  transaction,  contribution  or  other  tax  on  either  the
Upper-Tier REMIC, the Lower-Tier REMIC or the Trust Estate. The Master Servicer,
or,  in the  case  of any tax  return  or  other  action  required  by law to be
performed directly by the Trustee, the Trustee, shall (i) prepare or cause to be
prepared, timely cause to be signed by the Trustee and file or cause to be filed
annual federal and applicable state and local income tax



<PAGE>



returns  for each of the  Upper-Tier  REMIC  and the  Lower-Tier  REMIC  using a
calendar year as the taxable year and the accrual method of accounting;  (ii) in
the  first  such  federal  tax  returns,  make,  or cause to be made,  elections
satisfying  the  requirements  of the REMIC  Provisions,  on behalf of the Trust
Estate,  to treat each of the  Upper-Tier  REMIC and the  Lower-Tier  REMIC as a
REMIC; (iii) prepare, execute and forward, or cause to be prepared, executed and
forwarded,  to the  Certificateholders  all  information  reports or tax returns
required with respect to the Trust  Estate,  as and when required to be provided
to the  Certificateholders,  and to the Internal  Revenue  Service and any other
relevant  governmental  taxing authority in accordance with the REMIC Provisions
and any  other  applicable  federal,  state or  local  laws,  including  without
limitation information reports relating to "original issue discount" and "market
discount"  as  defined  in the Code  based  upon the  issue  prices,  prepayment
assumption  and cash flows  provided by the Seller to the Trustee and calculated
on a  monthly  basis by using the issue  prices of the  Certificates;  (iv) make
available  information  necessary  for the  application  of any tax  imposed  on
transferors of residual interests to "disqualified organizations" (as defined in
the REMIC Provisions);  (v) file Forms SS-4 and 8811 and respond to inquiries by
Certificateholders or their nominees concerning information returns,  reports or
tax returns;  (vi) maintain (or cause to be maintained  by the  Servicers)  such
records relating to the Upper-Tier REMIC and the Lower-Tier REMIC, including but
not limited to the income,  expenses,  individual  Mortgage Loans (including REO
Mortgage Loans,  other assets and liabilities of each REMIC, and the fair market
value and  adjusted  basis of the  property  of each  REMIC  determined  at such
intervals  as may be required by the Code,  as may be  necessary  to prepare the
foregoing returns or information reports;  (vii) exercise reasonable care not to
allow the  creation of any  "interests"  in either the  Upper-Tier  REMIC or the
Lower-Tier  REMIC within the meaning of Code Section  860D(a)(2)  other than the
interests in the Upper-Tier REMIC represented by the Class A-7 Scheduled Accrual
Component, Class A-7 IO A Component, Class A-7 IO B Component and Class A-7 IO C
Component, the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6,
Class A-8, Class A-9, Class A-10,  Class A-11, Class A-PO, Class A-WIO and Class
A-R  Certificates,  the Class M Certificates and the Class B-l, Class B-2, Class
B-3,  Class B-4 and Class B-5  Certificates  and the interests in the Lower-Tier
REMIC  represented by the Class A-L1,  Class A-L2, Class A-L4, Class A-L7, Class
A-L8,  Class A-LPO,  A-LWIO,  Class A-LUR,  Class B-L1,  Class B-L2, Class B-L3,
Class B-L4,  Class B-L5 and Class M-L Interests and the Class A-LR  Certificate;
(viii)  exercise  reasonable care not to allow the occurrence of any "prohibited
transactions"  within the  meaning of Code  Section  860F(a),  unless the Master
Servicer  shall have  provided  an Opinion of Counsel to the  Trustee  that such
occurrence would not (a) result in a taxable gain, (b) otherwise  subject either
the Upper-Tier REMIC or Lower-Tier REMIC or the Trust Estate to tax or (c) cause
the Trust  Estate to fail to  qualify  as two  separate  REMICs;  (ix)  exercise
reasonable care not to allow either the Upper-Tier REMIC or the Lower-Tier REMIC
to receive income from the  performance of services or from assets not permitted
under  the REMIC  Provisions  to be held by a REMIC;  (x) pay (on  behalf of the
Upper-Tier REMIC or the Lower-Tier  REMIC) the amount of any federal income tax,
including, without limitation, prohibited transaction taxes, taxes on net income
from foreclosure  property,  and taxes on certain contributions to a REMIC after
the Startup Day,  imposed on the Upper-Tier  REMIC or Lower-Tier  REMIC,  as the
case may be, when and as the same shall be due and payable (but such  obligation
shall not prevent the Master Servicer or any other appropriate Person from



<PAGE>



contesting  any such tax in  appropriate  proceedings  and shall not prevent the
Master Servicer from withholding or depositing payment of such tax, if permitted
by law,  pending  the  outcome of such  proceedings);  and (xi) if  required  or
permitted by the Code and  applicable  law, act as "tax matters  person" for the
Upper-Tier  REMIC  or the  Lower-Tier  REMIC  within  the  meaning  of  Treasury
Regulations Section 1.860F-4(d), and the Master Servicer is hereby designated as
agent of the Class A-R and Class A-LR Certificateholders for such purpose (or if
the Master Servicer is not so permitted,  the Holders of the Class A-R and Class
A-LR  Certificates  shall be tax matters  persons in  accordance  with the REMIC
Provisions).  The Master Servicer shall be entitled to be reimbursed pursuant to
Section  3.02 for any taxes paid by it pursuant  to clause (x) of the  preceding
sentence,  except to the extent  that such taxes are  imposed as a result of the
bad faith, willful misfeasance or gross negligence of the Master Servicer in the
performance of its obligations hereunder. The Trustee shall sign the tax returns
referred to in clause (i) of the second preceding  sentence.  In order to enable
the Master Servicer or the Trustee, as the case may be, to perform its duties as
set forth above,  the Seller  shall  provide,  or cause to be  provided,  to the
Master  Servicer  within ten days after the Closing Date all information or data
that the Master  Servicer  determines  to be  relevant  for tax  purposes to the
valuations  and  offering  prices  of  the  Certificates,   including,   without
limitation,  the price, yield, prepayment assumption and projected cash flows of
each Class and Subclass of Certificates and the Mortgage Loans in the aggregate.
Thereafter,  the Seller shall provide to the Master Servicer or the Trustee,  as
the case may be, promptly upon request therefor, any such additional information
or data that the Master  Servicer or the  Trustee,  as the case may be, may from
time to time,  request  in order to enable the Master  Servicer  to perform  its
duties as set forth above. The Seller hereby  indemnifies the Master Servicer or
the Trustee, as the case may be, for any losses, liabilities, damages, claims or
expenses  of the  Master  Servicer  or the  Trustee  arising  from any errors or
miscalculations  by the Master Servicer or the Trustee  pursuant to this Section
that  result  from any  failure  of the  Seller  to  provide,  or to cause to be
provided, accurate information or data to the Master Servicer or the Trustee, as
the case may be, on a timely basis.  The Master Servicer hereby  indemnifies the
Seller and the Trustee for any losses, liabilities,  damages, claims or expenses
of the  Seller  or the  Trustee  arising  from  the  Master  Servicer's  willful
misfeasance,  bad faith or gross  negligence  in  preparing  any of the federal,
state and local tax returns of the REMIC as described  above.  In the event that
the  Trustee  prepares  any of the  federal,  state and local tax returns of the
REMIC as described  above,  the Trustee  hereby  indemnifies  the Seller and the
Master Servicer for any losses, liabilities,  damages, claims or expenses of the
Seller and the Master Servicer arising from the Trustee's  willful  misfeasance,
bad faith or negligence in connection with such preparation.

     (b) Notwithstanding anything in this Agreement to the contrary, each of the
Master Servicer and the Trustee shall pay from its own funds,  without any right
of  reimbursement  therefor,  the amount of any costs,  liabilities and expenses
incurred  by the  Trust  Estate  (including,  without  limitation,  any  and all
federal,   state  or  local  taxes,   including  taxes  imposed  on  "prohibited
transactions"  within the meaning of the REMIC  Provisions) if and to the extent
that such costs,  liabilities  and  expenses  arise from a failure of the Master
Servicer or the Trustee to perform its obligations under this Section 8.14.

Section 8.15.      Monthly Advances.

     In the  event  that  Norwest  Mortgage  fails  to make a  Periodic  Advance
required to be made pursuant to the Norwest Servicing Agreement on or before the
Distribution  Date,  the  Trustee  shall make a Periodic  Advance as required by
Section 3.03 hereof;  provided,  however,  the Trustee  shall not be required to
make such Periodic  Advances if prohibited by law or if it determines  that such
Periodic  Advance  would be a  Nonrecoverable  Advance.  With  respect  to those
Periodic Advances which should have been made by Norwest  Mortgage,  the Trustee
shall be entitled,  pursuant to Section  3.02(a)(i),  (ii) or (v) hereof,  to be
reimbursed from the Certificate Account for Periodic Advances and Nonrecoverable
Advances made by it.

Seller or Liquidation of All Mortgage Loans.

     Subject to Section 9.02, the respective obligations and responsibilities of
the Seller,  the Master  Servicer and the Trustee created hereby (other than the
obligation of the Trustee to make certain payments after the Final  Distribution
Date to  Certificateholders  and the  obligation of the Master  Servicer to send

and all property acquired in respect of any Mortgage Loan remaining in the Trust
Estate at a price equal to the sum of (x) 100% of the unpaid  principal  balance
of each  Mortgage  Loan  (other  than any REO  Mortgage  Loan)  as of the  Final
Distribution  Date,  and (y) the fair  market  value of the  Mortgaged  Property
related to any REO Mortgage Loan (as determined by the Master Servicer as of the

Mortgagor  under a defaulted  Mortgage Loan on which a Servicer is not obligated
to foreclose due to environmental impairment) or the disposition of all property
acquired upon  foreclosure  or deed in lieu of foreclosure of any Mortgage Loan;
provided,  however,  that in no event shall the trust  created  hereby  continue
beyond 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, living on the date hereof.

     The right of the  Seller to  purchase  all the  assets of the Trust  Estate
pursuant to clause (i) of the  preceding  paragraph  are subject to Section 9.02
and conditioned upon the Pool Scheduled  Principal Balance of the Mortgage Loans
as of the  Final  Distribution  Date  being  less than the  amount  set forth in
Section 11.26. In the case of any purchase by the Seller pursuant to said clause
(i),  the Seller  shall  provide to the  Trustee the  certification  required by
Section 3.04 and the Trustee and the Custodian shall, promptly following payment
of the  purchase  price,  release to the Seller  the Owner  Mortgage  Loan Files
pertaining to the Mortgage Loans being purchased.

     Notice of any termination,  specifying the Final  Distribution  Date (which
shall be a date that  would  otherwise  be a  Distribution  Date) upon which the
Certificateholders  may surrender their  Certificates to the Trustee for payment
of the final  distribution  and  cancellation,  shall be given  promptly  by the
Master Servicer (if it is exercising its right to purchase the



<PAGE>



assets of the Trust  Estate) or by the  Trustee (in any other case) by letter to
Certificateholders  mailed not earlier than the 15th day of the month  preceding
the month of such final distribution and not later than the twentieth day of the
month of such final distribution specifying (A) the Final Distribution Date upon
which  final  payment of the  Certificates  will be made upon  presentation  and
surrender  of  Certificates  at the  office  or agency  of the  Trustee  therein
designated,  (B) the  amount of any such final  payment  and (C) that the Record
Date otherwise applicable to such Distribution Date is not applicable,  payments
being made (except in the case of any Class A Certificate surrendered on a prior
Distribution Date pursuant to Section 4.01) only upon presentation and surrender
of the Certificates at the office or agency of the Trustee therein specified. If
the  Master  Servicer  is  obligated  to give  notice to  Certificateholders  as
aforesaid,  it  shall  give  such  notice  to the  Trustee  and the  Certificate
Registrar at the time such notice is given to  Certificateholders.  In the event
such notice is given by the Master  Servicer,  the Master Servicer shall deposit
in  the  Certificate  Account  on or  before  the  Final  Distribution  Date  in
immediately available funds an amount equal to the purchase price for the assets
of the Trust  Estate  computed  as above  provided.  Failure  to give  notice of
termination  as described  herein shall not entitle a  Certificateholder  to any
interest beyond the interest payable on the Final Distribution Date.

     Upon  presentation  and  surrender of the  Certificates,  the Trustee shall
cause to be distributed to  Certificateholders on the Final Distribution Date in
proportion to their respective Percentage Interests an amount equal to (i) as to
the  Subclasses  of  Class A  Certificates,  the  respective  Class  A  Subclass
Principal  Balance  together with any related Class A Subclass  Unpaid  Interest
Shortfall and one month's  interest in an amount equal to the respective Class A
Subclass Interest Accrual Amount, (ii) as to the Class M Certificates, the Class
M Principal Balance together with any related Class M Unpaid Interest  Shortfall
and one  month's  interest  at the  Class  M  Pass-Through  Rate on the  Class M
Principal  Balance,  (iii) as to the  Subclasses  of Class B  Certificates,  the
respective Class B Subclass  Principal Balance together with any related Class B
Subclass Unpaid Interest  Shortfall and one month's  interest in an amount equal
to the respective  Class B Subclass  Interest  Accrual Amount and (iv) as to the
Class A-R and Class A-LR  Certificates,  the  amounts,  if any,  which remain on
deposit in the  Upper-Tier  Certificate  Account  and the  Certificate  Account,
respectively  (other than  amounts  retained to meet claims)  after  application
pursuant to clauses (i), (ii) and (iii) above and payment to the Master Servicer
of any amounts it is entitled as  reimbursement  or  otherwise  hereunder.  Such
amount shall be  distributed  in respect of interest and principal in respect of
the  Uncertificated  Lower-Tier  Interests in the same amounts as distributed to
their Corresponding  Upper-Tier Class,  Classes,  Component or Components in the
manner specified in Section 4.01(a)(ii).  Notwithstanding the foregoing,  if the
price paid  pursuant to clause (i) of the first  paragraph of this Section 9.01,
after reimbursement to the Servicers, the Master Servicer and the Trustee of any
Periodic  Advances,  is  insufficient  to pay in full the  amounts  set forth in
clauses (i), (ii) and (iii) of this paragraph,  then any shortfall in the amount
available for distribution to Certificateholders shall be allocated in reduction
of the amounts  otherwise  distributable on the Final  Distribution  Date in the
same manner as Realized  Losses are allocated  pursuant to Sections  4.02(b) and
4.02(g) hereof.  Such  distribution on the Final  Distribution  Date shall be in
lieu of the distribution otherwise required to be made on such Distribution Date
in respect of each Class of Certificates.



<PAGE>



     In the event that all of the  Certificateholders  shall not surrender their
Certificates  for final payment and  cancellation  within three months following
the Final  Distribution Date, the Trustee shall on such date cause all funds, if
any,  in the  Certificate  Account  not  distributed  in final  distribution  to
Certificateholders  to be  withdrawn  therefrom  and  credited to the  remaining
Certificateholders by depositing such funds in a separate escrow account for the
benefit of such Certificateholders, and the Master Servicer (if it exercised its
right to purchase  the assets of the Trust  Estate) or the Trustee (in any other
case) 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  three months after the second  notice all the
Certificates  shall not have been surrendered for cancellation,  the Trustee may
take appropriate  steps, or may appoint an agent to take  appropriate  steps, to
contact  the  remaining   Certificateholders   concerning   surrender  of  their
Certificates,  and the cost thereof shall be paid out of the funds on deposit in
such escrow account.

Section 9.02.      Additional Termination Requirements.

     In the event of a termination  of the Trust Estate upon the exercise by the
Seller of its  purchase  option as provided in Section  9.01,  the Trust  Estate
shall be terminated in accordance  with the following  additional  requirements,
unless the  Trustee  has  received  an Opinion of Counsel to the effect that any
other manner of termination (i) will constitute a "qualified liquidation" of the
Trust Estate within the meaning of Code Section  860F(a)(4)(A) and (ii) will not
subject  either the Upper-Tier  REMIC or the Lower-Tier  REMIC to federal tax or
cause the Trust  Estate to fail to  qualify as two  separate  REMICs at any time
that any Certificates are outstanding:

          (i) The notice given by the Master  Servicer  under Section 9.01 shall
     provide  that such notice  constitutes  the  adoption of a plan of complete
     liquidation of the Upper-Tier  REMIC and Lower-Tier REMIC as of the date of
     such notice  (or,  if  earlier,  the date on which the first such notice is
     mailed to Certificateholders).  The Master Servicer shall also specify such
     date in a statement  attached  to the final tax  returns of the  Upper-Tier
     REMIC and Lower-Tier REMIC; and

          (ii) At or  after  the  time of  adoption  of such a plan of  complete
     liquidation  and at or prior to the Final  Distribution  Date,  the Trustee
     shall sell all of the assets of the Trust  Estate to the Seller for cash at
     the purchase price specified in Section 9.01 and shall distribute such cash
     within 90 days of such adoption in the manner specified in Section 9.01.

correct or supplement any provisions herein or therein which may be inconsistent
with any other provisions herein or therein,  (iii) to modify,  eliminate or add
to any of its  provisions  to such extent as shall be  necessary to maintain the

REMIC  pursuant  to the Code that  would be a claim  against  the Trust  Estate,
provided  that (a) the Trustee has  received an Opinion of Counsel to the effect
that such action is necessary or desirable to maintain such  qualification or to
avoid or minimize the risk of the imposition of any such tax and (b) such action
shall not, as  evidenced  by such  Opinion of Counsel,  adversely  affect in any
material  respect the  interests  of any  Certificateholder,  (iv) to change the
timing  and/or nature of deposits into the  Upper-Tier  Certificate  Account and

then-current  rating of the  Certificates  as  evidenced  by a letter  from each
Rating Agency to such effect, (v) to modify,  eliminate or add to the provisions
of Section  5.02 or any other  provisions  hereof  restricting  transfer  of the
Certificates, provided that the Master Servicer for purposes of Section 5.02 has
determined in its sole discretion that any such  modifications to this Agreement
will neither  adversely affect the rating on the Certificates nor give rise to a
risk that  either the  Upper-Tier  REMIC or the  Lower-Tier  REMIC or any of the
Certificateholders  will  be  subject  to  a  tax  caused  by  a  transfer  to a
non-permitted  transferee and (vi) to make any other  provisions with respect to
matters or questions  arising under this Agreement or such  Custodial  Agreement
which  shall  not  be  materially  inconsistent  with  the  provisions  of  this
Agreement,  provided  that such action  shall not, as evidenced by an Opinion of
Counsel,  adversely  affect  in  any  material  respect  the  interests  of  any
Certificateholder.

     This Agreement or any Custodial  Agreement may also be amended from time to
time by the Seller,  the Master Servicer and the Trustee with the consent of the
Holders of Certificates evidencing in the aggregate not less than 66-2/3% of the
aggregate  Voting  Interests of each Class or Subclass 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 such Custodial  Agreement
or of modifying in any manner the rights of the Holders of  Certificates of such
Class or Subclass; provided, however, that no such amendment shall (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



<PAGE>



of such Certificate,  (ii) adversely affect in any material respect the interest
of the Holders of  Certificates  of any Class or Subclass in a manner other than

Interests  aggregating  not less than  66-2/3%  or (iii)  reduce  the  aforesaid
percentage  of  Certificates  of any Class or Subclass  the Holders of which are
required to consent to any such amendment, without the consent of the Holders of
all Certificates of such Class or Subclass then outstanding.

     Notwithstanding  any contrary provision of this Agreement the Trustee shall
not  consent  to any  amendment  to this  Agreement  unless it shall  have first
received  an  Opinion of Counsel  to the  effect  that such  amendment  will not
subject  either the  Upper-Tier  REMIC or the  Lower-Tier  REMIC to tax or cause
either  the  Upper-Tier  REMIC or the  Lower-Tier  REMIC to fail to qualify as a
REMIC at any time that any Certificates are outstanding.

     Promptly  after the  execution of any  amendment  requiring  the consent of
Certificateholders,  the  Trustee  shall  furnish  written  notification  of the
substance of such amendment to each Certificateholder.

     It shall not be necessary for the consent of Certificateholders  under this
Section 10.01(a) 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  Certificateholders  shall be  subject to such  reasonable
regulations as the Trustee may prescribe.

     (b)  Notwithstanding  any contrary provision of this Agreement,  the Master
Servicer may, from time to time,  amend Schedule I hereto without the consent of
any Certificateholder or the Trustee; provided, however, (i) that such amendment
does not conflict with any provisions of the related Servicing  Agreement,  (ii)
that the related Servicing Agreement provides for the remittance of each type of
Unscheduled  Principal  Receipts received by such Servicer during the Applicable
Unscheduled   Principal   Receipt  Period  (as  so  amended)   related  to  each
Distribution Date to the Master Servicer no later than the 24th day of the month
in which such  Distribution Date occurs and (iii) that such amendment is for the
purpose of:

          (a) changing the Applicable  Unscheduled  Principal Receipt Period for
     Exhibit F-1 Mortgage  Loans to a Mid-Month  Receipt  Period with respect to
     all Unscheduled Principal Receipts; or

          (b) changing the Applicable  Unscheduled  Principal Receipt Period for
     all Mortgage Loans  serviced by any Servicer to a Mid-Month  Receipt Period
     with respect to Full  Unscheduled  Principal  Receipts and to a Prior Month
     Receipt Period with respect to Partial Unscheduled Principal Receipts.

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 the
Trust Estate,  nor otherwise  affect the rights,  obligations and liabilities of
the parties hereto or any of them.

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
Estate, 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.

     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

hereinbefore  provided,  and unless also the Holders of Certificates  evidencing
not less than 25% of the Voting Interest  represented by all Certificates  shall

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 60 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;  it being
understood   and   intended,    and   being   expressly   covenanted   by   each
Certificateholder  with every other  Certificateholder  and the Trustee, that no

provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

     Pursuant to the terms of the Agreement,  a distribution will be made on the
25th day of each month or, if such 25th day is not a Business  Day, the Business
Day immediately  following (the  "Distribution  Date"),  commencing on the first
Distribution  Date specified above, to the Person in whose name this Certificate
is  registered  at the close of business on the last  Business  Day of the month
preceding the month of such  distribution,  in an amount equal to the product of
the Percentage  Interest  evidenced by this Certificate and the Class A Subclass
Distribution Amount for the Class A-7 Certificates required to be distributed to
Holders  of  Class  A-7  Certificates  on such  Distribution  Date,  subject  to
adjustment in certain  events as specified in the  Agreement.  Distributions  in
reduction of the principal balance of certain Subclasses of Class A Certificates
may not commence on the first  Distribution Date specified above.  Distributions
of principal will be allocated  among the Subclasses of Class A Certificates  in

distributions of interest and in reduction of principal  balance,  the Class A-7
Certificates  consist of four components  (each, a "Component" and individually,
the "Class A-7 Scheduled  Accrual  Component,"  "Class A-7 IO A Component,"  the
"Class A-7 IO B Component"  and the "Class A-7 IO C  Component").  The amount of
interest which accrues on the Class A-7 Certificates in any month will equal the
sum of the interest  which  accrues on the Class A-7  Components.  The component
rate (the  "Component  Rate") on (i) the Class A-7 Scheduled  Accrual  Component
applicable to each  Distribution  Date will be 7.250% per annum,  (ii) the Class

each Distribution  Date will be 0.150% per annum.  Interest with respect to each
Component will accrue during each month in an amount equal to the product of (i)
1/12th  of the  Component  Rate for  such  Component  and  (ii) the  outstanding
Component  Principal  Balance  in the case of the  Class A-7  Scheduled  Accrual
Component or the  outstanding  notional amount in the case of the Class A-7 IO A
Component,  Class A-7 IO B Component or Class A-7 IO C  Component.  Prior to the
Class  A-7  Scheduled   Accrual   Component   Accretion   Termination  Date,  no
distribution  of  interest  on this  Certificate  with  respect to its Class A-7
Scheduled  Accrual  Component  will be made.  Prior to the Class  A-7  Scheduled
Accrual Component  Accretion  Termination Date, interest otherwise available for

respect  to its  Class  A-7  Scheduled  Accrual  Component  will be added to the
Component  Principal  Balance of such Component on each  Distribution  Date. The

subject to reduction with respect to any  Non-Supported  Interest  Shortfall and
the  interest  portion of certain  Realized  Losses  allocated  to the Class A-7
Certificates with respect to their Components.

     Distributions  on this  Certificate  will be made on behalf of the  Trustee
either by the  Master  Servicer  or by a Paying  Agent  appointed  by the Master
Servicer by check mailed to the address of the Person entitled thereto,  as such
name and address shall appear on the Certificate Register, unless such Person is
entitled to receive payments by wire transfer in immediately  available funds in
accordance with the Pooling and Servicing Agreement and such Person has notified
the Master  Servicer  pursuant to the Pooling and Servicing  Agreement that such
payments  are to be  made by  wire  transfer  of  immediately  available  funds.
Notwithstanding  the above, the final distribution in reduction of the principal
balance of this  Certificate  will be made after due notice of the  pendency  of
such  distribution and only upon  presentation and surrender of this Certificate
at the office or agency  specified by the Trustee for that purpose in the notice
of final distribution.

     No transfer of a Class A-7 Certificate will be made unless such transfer is
exempt from the  registration  requirements  of the  Securities  Act of 1933, as
amended (the "Act"),  and any  applicable  state  securities  laws or is made in
accordance  with the Act and laws.  In the event that such a transfer is desired
to be made by the Holder hereof,  (i) the transferee will be required to execute
an  investment  letter in the form  described in the  Agreement and (ii) if such
transfer  is to be made  within  three  years  from the later of (a) the date of
initial issuance of the Certificates or (b) the last date on which the Seller or
any  affiliate  thereof  was  a  Holder  of  the  Certificates  proposed  to  be
transferred,  and unless  such  transfer is made in reliance on Rule 144A of the
Act,  the  Trustee or the Seller may require the Holder to deliver an opinion of
counsel acceptable to and in form and substance  satisfactory to the Trustee and
the Seller that such transfer is exempt (describing the applicable exemption and
the  basis  therefor)  from  or is  being  made  pursuant  to  the  registration
requirements of the Act and of any applicable  statute of any state.  The Holder
hereof  desiring  to effect  such  transfer  shall,  and does  hereby  agree to,
indemnify the Trustee,  the Seller,  the Master  Servicer,  and any Paying Agent
acting on behalf of the  Trustee  against any  liability  that may result if the
transfer  is not so exempt or is not made in  accordance  with such  federal and
state laws. In connection with any such transfer,  the Trustee will also require
if the  transferee  is a Plan or a person  acting on behalf of or investing  the
assets of a Plan,  a  representation  letter,  in the form as  described  in the
Agreement,  stating that such transferee is an "accredited  investor" as defined
in Rule 501(a)(1) of the Act.

     Reference is hereby made to the further  provisions of this Certificate set
forth on the reverse  hereof,  which further  provisions  shall for all purposes
have the same effect as if set forth at this place.

corporations   (the  "Mortgage   Loans")  formed  by  Norwest  Asset  Securities

pursuant to a Pooling and Servicing  Agreement  dated as of August 29, 1997 (the
"Agreement") among the Seller, Norwest Bank Minnesota,  National Association, as
master  servicer  (the "Master  Servicer")  and First Union  National  Bank,  as

capitalized  terms used herein have the  meanings  ascribed to such terms in the
Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

     Pursuant to the terms of the Agreement,  a distribution will be made on the

is  registered  at the close of business on the last  Business  Day of the month
preceding the month of such  distribution,  in an amount equal to the product of

agency  specified  by the  Trustee  for  that  purpose  in the  notice  of final

amended,  and any applicable state securities laws or is made in accordance with
said Act and laws.  In the event that such a  transfer  is desired to be made by
the Holder hereof,  (i) the transferee will be required to execute an investment

applicable  exemption and the basis  therefor) from or is being made pursuant to
the registration  requirements of the Securities Act of 1933, as amended, and of
any applicable  statute of any state.  The Holder hereof desiring to effect such
transfer shall, and does hereby agree to, indemnify the Trustee, the Seller, the
Master  Servicer,  and any Paying Agent acting on behalf of the Trustee  against
any liability that may result if the transfer is not so exempt or is not made in
accordance  with  such  Federal  and state  laws.  In  connection  with any such
transfer, the Trustee will also require (i) a representation letter, in the form
as described in the Agreement,  stating that the transferee is not a Plan and is
not  acting on behalf  of a Plan or using  the  assets of a Plan to effect  such
purchase  or (ii) if  such  transferee  is a Plan,  (a) an  opinion  of  counsel
acceptable  to and in form and  substance  satisfactory  to the  Trustee and the
Seller with respect to certain matters and (b) such other  documentation  as the
Seller or the Master Servicer may require, as described in the Agreement.

pursuant to a Pooling and Servicing  Agreement  dated as of August 29, 1997 (the
"Agreement") among the Seller, Norwest Bank Minnesota,  National Association, as
master  servicer  (the "Master  Servicer")  and First Union  National  Bank,  as
trustee (the  "Trustee"),  a summary of certain of the  pertinent  provisions of
which  is  set  forth  hereinafter.  To  the  extent  not  defined  herein,  the
capitalized  terms used herein have the  meanings  ascribed to such terms in the
Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

     Pursuant to the terms of the Agreement,  a distribution will be made on the
25th day of each month or, if such 25th day is not a Business  Day, the Business
Day immediately  following (the  "Distribution  Date"),  commencing on the first
Distribution  Date specified above, to the Person in whose name this Certificate
is  registered  at the close of business on the last  Business  Day of the month
preceding the month of such  distribution,  in an amount equal to the product of
the Percentage  Interest evidenced by this Certificate and, subject to the prior
rights of the Class A Certificates,  the Class M Certificates  and each Subclass
of Class B Certificates  bearing a lower  numerical  designation as specified in
the Agreement,  any Class B-3 Distribution  Amount required to be distributed to
Holders  of  Class  B-3  Certificates  on such  Distribution  Date,  subject  to

any month  will be  subject  to  reduction  with  respect  to any  Non-Supported
Interest Shortfall and the interest portion of certain Realized Losses allocated
to the Class B-3 Certificates, as described in the Agreement.

     Distributions  on this  Certificate  will be made on behalf of the  Trustee
either by the  Master  Servicer  or by a Paying  Agent  appointed  by the Master

Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  specified  by the  Trustee  for  that  purpose  in the  notice  of final
distribution.

exempt from the  registration  requirements  of the  Securities  Act of 1933, as
amended,  and any applicable state securities laws or is made in accordance with
said Act and laws.  In the event that such a  transfer  is desired to be made by
the Holder hereof,  (i) the transferee will be required to execute an investment
letter in the form described in the Agreement and (ii) if such transfer is to be
made within  three  years from the later of (a) the date of initial  issuance of
the Certificates or (b) the last

date  on  which  the  Seller  or  any  affiliate  thereof  was a  Holder  of the
Certificates  proposed to be  transferred,  and unless such  transfer is made in
reliance on Rule 144A of the Securities Act of 1933, as amended,  the Trustee or
the Seller may require the Holder to deliver an opinion of counsel acceptable to
and in form and substance  satisfactory  to the Trustee and the Seller that such
transfer is exempt (describing the applicable  exemption and the basis therefor)
from  or is  being  made  pursuant  to  the  registration  requirements  of  the
Securities Act of 1933, as amended,  and of any applicable statute of any state.
The Holder hereof desiring to effect such transfer shall,  and does hereby agree
to, indemnify the Trustee, the Seller, the Master Servicer, and any Paying Agent
acting on behalf of the  Trustee  against any  liability  that may result if the
transfer  is not so exempt or is not made in  accordance  with such  Federal and
state laws. In  connection  with any such  transfer,  the Trustee and the Seller
will also require (i) a representation  letter,  in the form as described in the
Agreement, stating that the transferee is not a Plan and is not acting on behalf
of a Plan or using the assets of a Plan to effect such  purchase or (ii) if such
transferee  is a Plan,  (a) an opinion of counsel  acceptable to and in form and
substance  satisfactory  to the Trustee  and the Seller with  respect to certain
matters and (b) such other  documentation  as the Seller or the Master  Servicer
may require, as described in the Agreement.

     Reference is hereby made to the further  provisions of this Certificate set
forth on the reverse  hereof,  which further  provisions  shall for all purposes
have the same effect as if set forth at this place.

     This Certificate is issued on August 29, 1997, and based on its issue price
of 87.17326%,  including  accrued  interest,  and a stated  redemption  price at
maturity equal to its initial  principal  balance (plus four days of interest at
the  Pass-Through  Rate hereon),  is issued with original issue discount ("OID")
for  federal  income  tax  purposes.  Assuming  that  this  Certificate  pays in
accordance  with  projected cash flows  reflecting the Prepayment  Assumption of
275% SPA (as defined in the  Prospectus  Supplement  dated  August 22, 1997 with
respect to the offering of the Class A-1, A-2,  Class A-3, Class A-4, Class A-5,
Class A-6, Class A-8, Class A-9, Class A-10, Class A-11, Class A-WIO, Class A-R,
Class A-LR,  Class M, Class B-1 and Class B-2  Certificates)  used to price this
Certificate:  (i) the amount of OID as a  percentage  of the  initial  principal
balance of this Certificate is approximately 12.90729167%; (ii) the annual yield
to maturity of this Certificate, compounded monthly, is approximately 9.23%; and
(iii) the amount of OID allocable to the short first accrual  period (August 29,
1997 to September 25, 1997) as a percentage of the initial  principal balance of
this   Certificate,   calculated  using  the  exact  method,   is  approximately
0.05713344%.

     This  Certificate  constitutes  a  "regular  interest"  in a  "real  estate
mortgage  investment  conduit" as those terms are defined in Section  860G(a)(1)

Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  specified  by the  Trustee  for  that  purpose  in the  notice  of final
distribution.

exempt from the  registration  requirements  of the  Securities  Act of 1933, as
amended,  and any applicable state securities laws or is made in accordance with
said Act and laws.  In the event that such a  transfer  is desired to be made by
the Holder hereof,  (i) the transferee will be required to execute an investment

date  on  which  the  Seller  or  any  affiliate  thereof  was a  Holder  of the
Certificates  proposed to be  transferred,  and unless such  transfer is made in
reliance on Rule 144A of the Securities Act of 1933, as amended,  the Trustee or
the Seller may require the Holder to deliver an opinion of counsel acceptable to
and in form and substance  satisfactory  to the Trustee and the Seller that such
transfer is exempt (describing the applicable  exemption and the basis therefor)
from  or is  being  made  pursuant  to  the  registration  requirements  of  the
Securities Act of 1933, as amended,  and of any applicable statute of any state.
The Holder hereof desiring to effect such transfer shall,  and does hereby agree
to, indemnify the Trustee, the Seller, the Master Servicer, and any Paying Agent
acting on behalf of the  Trustee  against any  liability  that may result if the
transfer  is not so exempt or is not made in  accordance  with such  Federal and
state laws. In  connection  with any such  transfer,  the Trustee and the Seller
will also require (i) a representation  letter,  in the form as described in the
Agreement, stating that the transferee is not a Plan and is not acting on behalf
of a Plan or using the assets of a Plan to effect such  purchase or (ii) if such
transferee  is a Plan,  (a) an opinion of counsel  acceptable to and in form and
substance  satisfactory  to the Trustee  and the Seller with  respect to certain
matters and (b) such other  documentation  as the Seller or the Master  Servicer
may require, as described in the Agreement.

     Reference is hereby made to the further  provisions of this Certificate set
forth on the reverse  hereof,  which further  provisions  shall for all purposes
have the same effect as if set forth at this place.

     This Certificate is issued on August 29, 1997, and based on its issue price
of 32.59514%,  including  accrued  interest,  and a stated  redemption  price at
maturity equal to its initial  principal  balance (plus four days of interest at
the  Pass-Through  Rate hereon),  is issued with original issue discount ("OID")
for  federal  income  tax  purposes.  Assuming  that  this  Certificate  pays in
accordance  with  projected cash flows  reflecting the Prepayment  Assumption of

respect to the offering of the Class A-1, A-2,  Class A-3, Class A-4, Class A-5,
Class A-6, Class A-8, Class A-9, Class A-10, Class A-11, Class A-WIO, Class A-R,
Class A-LR,  Class M, Class B-1 and Class B-2  Certificates)  used to price this
Certificate:  (i) the amount of OID as a  percentage  of the  initial  principal
balance of this Certificate is approximately 67.48541667%; (ii) the annual yield
to maturity of this Certificate,  compounded monthly,  is approximately  28.26%;
and (iii) the amount of OID allocable to the short first accrual  period (August
29, 1997 to September 25, 1997) as a percentage of the initial principal balance
of this  Certificate,  calculated  using  the  exact  method,  is  approximately
0.14064325%.

     This  Certificate  constitutes  a  "regular  interest"  in a  "real  estate
mortgage  investment  conduit" as those terms are defined in Section  860G(a)(1)
and  Section  860D,  respectively,  of the  Internal  Revenue  Code of 1986,  as
amended.

     Unless this Certificate has been  countersigned by an authorized officer of
the Trustee, by manual signature,  this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

pursuant to a Pooling and Servicing  Agreement  dated as of August 29, 1997 (the
"Agreement") among the Seller, Norwest Bank Minnesota,  National Association, as
master  servicer  (the "Master  Servicer")  and First Union  National  Bank,  as

preceding the month of such  distribution,  in an amount equal to the product of
the Percentage  Interest evidenced by this Certificate and, subject to the prior
rights of the Class A Certificates  as specified in the  Agreement,  any Class M
Distribution   Amount   required  to  be  distributed  to  Holders  of  Class  M
Certificates  on such  Distribution  Date,  subject  to  adjustment,  in certain
events, as specified in the Agreement.  The Class M Pass-Through Rate applicable

accrues on this  Certificate  in any month will be  subject  to  reduction  with

certain Realized Losses  allocated to the Class M Certificates,  as described in
the Agreement.

     Distributions  on this  Certificate  will be made on behalf of the  Trustee
either by the  Master  Servicer  or by a Paying  Agent  appointed  by the Master
Servicer by check mailed to the address of the Person entitled thereto,  as such
name and address shall appear on the Certificate  Register.  Notwithstanding the

Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or

this  Certificate  is an "insurance  company  general  account," or (ii) if such
transferee  is a Plan,  (a) an opinion of counsel  acceptable to and in form and
substance satisfactory to the Trustee and the Seller with

                      NORWEST ASSET SECURITIES CORPORATION
                       MORTGAGE PASS-THROUGH CERTIFICATES
                                 SERIES 1997-12

     This Certificate is one of a duly authorized  issue of Certificates  issued
in  several   Classes  and  Subclasses   designated  as  Mortgage   Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

     The Certificates are limited in right of payment to certain collections and
recoveries  respecting the Mortgage Loans,  all as more  specifically  set forth
herein and in the Agreement. In the event funds are advanced with respect to any
Mortgage Loan by a Servicer,  the Master Servicer or the Trustee,  such advances
are  reimbursable  to such Servicer,  the Master  Servicer or the Trustee to the
extent provided in the Agreement,  from related recoveries on such Mortgage Loan
or from other cash that would have been distributable to Certificateholders.

     As provided in the  Agreement,  withdrawals  from the  Certificate  Account
created for the benefit of Certificateholders may be made by the Master Servicer
from time to time for purposes other than  distributions to  Certificateholders,
such purposes including  reimbursement to a Servicer, the Master Servicer or the
Trustee, as applicable,  of advances made by such Servicer,  the Master Servicer
or the Trustee.

     The  Agreement  permits,  with certain  exceptions  therein  provided,  the
amendment of the Agreement and the modification of the rights and obligations of
the  Seller,  the  Master  Servicer  and  the  Trustee  and  the  rights  of the
Certificateholders  under the  Agreement  at any time by the Seller,  the Master
Servicer  and the  Trustee  with the  consent  of the  Holders  of  Certificates
evidencing  in the  aggregate  not less than 66 2/3% of the Voting  Interests of
each Class or Subclass of Certificates affected thereby. Any such consent by the
Holder of this  Certificate  shall be conclusive  and binding on such Holder and
upon all future holders of this  Certificate and of any Certificate  issued upon
the  transfer  hereof or in  exchange  hereof or in lieu  hereof  whether or not
notation  of such  consent  is made upon the  Certificate.  The  Agreement  also
permits the amendment  thereof in certain  circumstances  without the consent of
the Holders of any of the Certificates.

     As provided in the Agreement and subject to certain limitations therein set
forth,  the  transfer of this  Certificate  is  registrable  in the  Certificate
Register upon surrender of this  Certificate for registration of transfer at the
office or agency  appointed by the Trustee,  duly endorsed by, or accompanied by
an assignment in the form below or other written  instrument of transfer in form
satisfactory to the Trustee and the Certificate Registrar,  duly executed by the
Holder  hereof  or such  Holder's  attorney  duly  authorized  in  writing,  and
thereupon one or more



<PAGE>



new  Certificates  of  authorized  Denominations  evidencing  the same Class and
Subclass and  aggregate  Percentage  Interest  will be issued to the  designated
transferee or transferees.

     The  Certificates  are issuable  only as  registered  Certificates  without
coupons in Classes and Denominations  specified in the Agreement. As provided in
the Agreement and subject to certain limitations therein set forth, Certificates
are exchangeable for new Certificates of authorized Denominations evidencing the
same Class and Subclass and aggregate Percentage  Interest,  as requested by the
Holder surrendering the same.

     No service  charge  will be made for any such  registration  of transfer or
exchange,  but the Trustee or the Certificate Registrar may require payment of a
sum  sufficient  to  cover  any tax or  other  governmental  charge  payable  in
connection therewith.

     The Seller, the Master Servicer, the Trustee and the Certificate Registrar,
and any agent of the Seller, the Master Servicer, the Trustee or the Certificate
Registrar,  may treat the Person in whose name this Certificate is registered as
the owner hereof for all purposes,  and neither the Seller, the Master Servicer,
the Trustee,  the Certificate  Registrar nor any such agent shall be affected by
notice to the contrary.

     The obligations created by the Agreement in respect of the Certificates and
the Trust Estate created  thereby shall  terminate upon the last action required
to be taken by the  Trustee  on the  Final  Distribution  Date  pursuant  to the
Agreement  following  the  earlier of (i) the payment or other  liquidation  (or
advance with respect  thereto) of the last Mortgage Loan subject  thereto or the
disposition  of all  property  acquired  upon  foreclosure  or  deed  in lieu of
foreclosure  of any Mortgage  Loan, and (ii) the purchase by the Seller from the
Trust  Estate of all  remaining  Mortgage  Loans and all  property  acquired  in
respect of such Mortgage Loans; provided, however, that the Trust Estate will in
no event  continue  beyond 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,  living on the date of the  Agreement.
The  Agreement  permits,  but does not  require,  the  Seller  to  purchase  all
remaining  Mortgage  Loans and all property  acquired in respect of any Mortgage
Loan at a price  determined as provided in the  Agreement.  The exercise of such
option will effect early retirement of the  Certificates,  the Seller's right to
exercise such option being subject to the Pool  Scheduled  Principal  Balance of
the Mortgage Loans as of the  Distribution  Date upon which the proceeds of such
repurchase  are  distributed  being less than ten  percent of the  Cut-Off  Date
Aggregate Principal Balance.

purposes  of  receiving  and holding  certain  documents  and other  instruments
delivered by the Seller under the Pooling and Servicing Agreement,  all upon the
terms and conditions and subject to the limitations hereinafter set forth;

     NOW,  THEREFORE,  in consideration of the premises and the mutual covenants
and  agreements  hereinafter  set forth,  the  Trustee,  the Seller,  the Master
Servicer and the Custodian hereby agree as follows:

                                    ARTICLE I

                                   Definitions

     Capitalized  terms used in this Agreement and not defined herein shall have
the meanings  assigned in the Original Pooling and Servicing  Agreement,  unless
otherwise required by the context herein.

                                   ARTICLE II

                          Custody of Mortgage Documents

     Section 2.1. Custodian to Act as Agent;  Acceptance of Custodial Files. The
Custodian,  as the duly  appointed  agent of the  Trustee  for  these  purposes,
acknowledges receipt of



<PAGE>



the Mortgage Notes, the Mortgages,  the assignments and other documents relating
to the Mortgage Loans  identified on the schedule  attached  hereto and declares
that it holds and will hold such  Mortgage  Notes,  Mortgages,  assignments  and
other documents and any similar documents  received by the Trustee subsequent to
the date hereof (the "Custodial Files") as agent for the Trustee,  in trust, for
the use and benefit of all present and future Certificateholders.

     Section 2.2. Recordation of Assignments. If any Custodial File includes one
or more assignments to the Trustee of Mortgage Notes and related  Mortgages that
have not been recorded, each such assignment shall be delivered by the Custodian
to the Seller for the purpose of recording it in the  appropriate  public office
for real property records, and the Seller, at no expense to the Custodian, shall
promptly cause to be recorded in the appropriate public office for real property
records each such  assignment and, upon receipt thereof from such public office,
shall return each such assignment to the Custodian.

     Section 2.3.  Review of Custodial  Files.  The  Custodian  agrees,  for the
benefit of  Certificateholders,  to review, in accordance with the provisions of
Section 2.01 of the Pooling and Servicing Agreement,  each Custodial File. If in
performing  the review  required  by this  Section 2.3 the  Custodian  finds any
document or documents  constituting  a part of a Custodial File to be missing or
defective in any material  respect,  the Custodian  shall promptly so notify the
Seller, the Master Servicer and the Trustee.

     Section 2.4.  Notification of Breaches of  Representations  and Warranties.
Upon  discovery by the Custodian of a breach of any  representation  or warranty
made by the  Seller  or the  Master  Servicer  as set forth in the  Pooling  and
Servicing  Agreement,  the  Custodian  shall give prompt  written  notice to the
Seller, the Master Servicer and the Trustee.

     Section 2.5.  Custodian to Cooperate;  Release of Custodial Files. Upon the
payment in full of any Mortgage Loan, or the receipt by the Master Servicer of a
notification  that  payment in full will be escrowed in a manner  customary  for
such purposes,  the Master Servicer shall immediately  notify the Custodian by a
certification  (which certification shall include a statement to the effect that
all amounts received or to be received in connection with such payment which are
required to be deposited in the Certificate  Account pursuant to Section 3.02 of
the Pooling and  Servicing  Agreement  have been or will be so  deposited)  of a
Servicing  Officer and shall request  delivery to it of the Custodial  File. The
Custodian agrees,  upon receipt of such  certification and request,  promptly to
release the related Custodial File to the Master Servicer.

     From time to time as is appropriate for the servicing or foreclosure of any
Mortgage Loan, the Master  Servicer shall deliver to the Custodian a certificate
of a Servicing  Officer  requesting  that  possession  of all,  or any  document
constituting  part of, the Custodial File be released to the Master Servicer and
certifying  as to the reason for such  release  and that such  release  will not
invalidate any insurance coverage provided in respect of the Mortgage Loan. With
such  certificate,  the Master Servicer shall deliver to the Custodian a receipt
signed by a Servicing Officer on behalf of the Master Servicer, and upon receipt
of the  foregoing,  the  Custodian  shall  deliver  the  Custodial  File or such
document to the Master Servicer.  The Master Servicer shall cause each Custodial

Loan has been liquidated and the Liquidation  Proceeds  relating to the Mortgage
Loan have been deposited in the  Certificate  Account to the extent  required by

                                   ARTICLE III

                            Concerning the Custodian

     Section 3.1.  Custodian a Bailee and Agent of the Trustee.  With respect to
each Mortgage Note,  Mortgage and other  documents  constituting  each Custodian
File which are  delivered to the  Custodian,  the Custodian is  exclusively  the
bailee  and agent of the  Trustee,  holds  such  documents  for the  benefit  of
Certificateholders and undertakes to perform such duties and only such duties as
are  specifically  set forth in this Agreement.  Except upon compliance with the
provisions of Section 2.5 of this Agreement, no Mortgage Note, Mortgage or other
document  constituting  a part of a  Custodial  File shall be  delivered  by the
Custodian to the Seller or the Master  Servicer or otherwise  released  from the
possession of the Custodian.

     Section 3.2.  Indemnification.  The Seller  hereby  agrees to indemnify and
hold the Custodian  harmless from and against all claims,  liabilities,  losses,
actions,  suits or proceedings at law or in equity, or any other expenses,  fees
or charges of any  character or nature,  which the  Custodian  may incur or with
which the  Custodian  may be  threatened  by reasons of its acting as  custodian
under this Agreement, including indemnification of the Custodian against any and
all expenses,  including  attorney's  fees if counsel for the Custodian has been
approved  by the  Seller,  and  the  cost  of  defending  any  action,  suit  or
proceedings  or  resisting  any  claim.  Notwithstanding  the  foregoing,  it is
specifically  understood and agreed that in the event any such claim, liability,
loss,  action,  suit or proceeding or other expense,  fees, or charge shall have
been caused by reason of any negligent act, negligent failure to act, or willful
misconduct  on the part of the  Custodian,  or which shall  constitute a willful
breach of its duties hereunder, the indemnification provisions of this Agreement
shall not apply.



<PAGE>



     Section  3.3.  Custodian  May  Own  Certificates.   The  Custodian  in  its
individual or any other capacity may become the owner or pledgee of Certificates
with the same rights it would have if it were not Custodian.

     Section 3.4.  Master  Servicer to Pay  Custodian's  Fees and Expenses.  The
Master Servicer  covenants and agrees to pay to the Custodian from time to time,
and the Custodian shall be entitled to, reasonable compensation for all services
rendered by it in the exercise and  performance  of any of the powers and duties
hereunder of the  Custodian,  and the Master  Servicer will pay or reimburse the
Custodian  upon its  request  for all  reasonable  expenses,  disbursements  and
advances  incurred  or made  by the  Custodian  in  accordance  with  any of the
provisions of this  Agreement  (including the  reasonable  compensation  and the
expenses and  disbursements  of its counsel and of all persons not  regularly in
its employ), except any such expense,  disbursement or advance as may arise from
its negligence or bad faith.

     Section  3.5.  Custodian  May  Resign;  Trustee May Remove  Custodian.  The
Custodian may resign from the  obligations  and duties hereby imposed upon it as
such  obligations  and duties  relate to its acting as Custodian of the Mortgage
Loans. Upon receiving such notice of resignation,  the Trustee shall either take
custody of the  Custodial  Files  itself and give prompt  notice  thereof to the
Seller,  the Master  Servicer and the Custodian or promptly  appoint a successor
Custodian by written  instrument,  in  duplicate,  one copy of which  instrument
shall be  delivered to the  resigning  Custodian  and one copy to the  successor
Custodian.  If the Trustee shall not have taken  custody of the Custodial  Files
and no  successor  Custodian  shall  have been so  appointed  and have  accepted
resignation,  the  resigning  Custodian  may  petition  any  court of  competent
jurisdiction for the appointment of a successor Custodian.

     The  Trustee  may remove the  Custodian  at any time.  In such  event,  the
Trustee shall appoint, or petition a court of competent jurisdiction to appoint,
a successor Custodian  hereunder.  Any successor Custodian shall be a depository
institution  subject to supervision or examination by federal or state authority
and shall be able to satisfy the other requirements contained in Section 3.7.

     Any  resignation or removal of the Custodian and appointment of a successor
Custodian  pursuant to any of the  provisions  of this  Section 3.5 shall become
effective upon acceptance of appointment by the successor Custodian. The Trustee
shall  give  prompt  notice  to  the  Seller  and  the  Master  Servicer  of the
appointment of any successor  Custodian.  No successor Custodian shall have been
appointed and accepted  appointment by the Trustee without the prior approval of
the Seller and the Master Servicer.

     Section 3.6. Merger or  Consolidation  of Custodian.  Any Person into which
the Custodian  may be merged or converted or with which it may be  consolidated,
or any Person  resulting from any merger,  conversion or  consolidation to which
the Custodian shall be a party, or any Person  succeeding to the business of the
Custodian,  shall be the  successor  of the  Custodian  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.

     Section  3.7.  Representations  of  the  Custodian.  The  Custodian  hereby
represents  that  it is a  depository  institution  subject  to  supervision  or
examination by a federal or state

File.

     Section 4.2.  Amendments.  No modification or amendment of or supplement to
this  Agreement  shall be valid or  effective  unless the same is in writing and
signed by all parties  hereto,  and neither the Seller,  the Master Servicer nor
the Trustee  shall enter into any  amendment  hereof  except as permitted by the
Pooling and  Servicing  Agreement.  The Trustee  shall give prompt notice to the
Custodian of any amendment or supplement to the Pooling and Servicing  Agreement
and furnish the Custodian with written copies thereof.

     Section 4.3.  Governing Law. This Agreement shall be deemed a contract made
under the laws of the State of New York and shall be  construed  and enforced in

applicable  law, this  Agreement is subject to  recordation  in all  appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the properties subject to the Mortgages are
situated,  and in any other  appropriate  public  recording office or elsewhere,
such  recordation  to be effected by the Master  Servicer  and at its expense on
direction by the Trustee,  but only upon direction  accompanied by an Opinion of
Counsel to the effect that such recordation  materially and beneficially affects
the interests of the Certificateholders.

     For the purpose of facilitating the recordation of this Agreement as herein
provided and for other purposes,  this Agreement may be executed  simultaneously
in any number of counterparts,  each of which counterparts shall be deemed to be

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 or of the Certificates
or the rights of the holders thereof.

[B-5]  Certificates") in the principal amount of $___________.  In doing so, the
Purchaser hereby acknowledges and agrees as follows:

     Section 1. Definitions. Each capitalized term used herein and not otherwise
defined  herein  shall  have  the  meaning  ascribed  to it in the  Pooling  and
Servicing  Agreement,  dated as of August 29, 1997 (the  "Pooling and  Servicing

Norwest Bank Minnesota,  National  Association,  as master servicer (the "Master

with the proposed transfer, the Purchaser represents and warrants to NASCOR, the
Master Servicer and the Trustee that:



<PAGE>



          (a) The  Purchaser  is duly  organized,  validly  existing and in good
     standing  under  the laws of the  jurisdiction  in which the  Purchaser  is
     organized,  is  authorized  to invest in the Class [A-7] [A-PO] [B-3] [B-4]
     [B-5] Certificates, and to enter into this Agreement, and duly executed and
     delivered this Agreement.

          (b) The  Purchaser  is  acquiring  the Class [A-7]  [A-PO] [B-3] [B-4]
     [B-5]  Certificates for its own account as principal and not with a view to
     the distribution thereof, in whole or in part.

          [(c) The Purchaser has knowledge of financial and business matters and
     is capable of evaluating the merits and risks of an investment in the Class
     [A-7] [A-PO] [B-3] [B-4] [B-5] Certificates;  the Purchaser has sought such
     accounting,  legal and tax advice as it has considered necessary to make an
     informed  investment  decision;  and the  Purchaser  is  able  to bear  the
     economic  risk of an investment in the Class [A-7] [A-PO] [B-3] [B-4] [B-5]
     Certificates and can afford a complete loss of such investment.]

          [(c) The  Purchaser is a "Qualified  Institutional  Buyer"  within the
     meaning of Rule 144A of the Act.]

          (d) The  Purchaser  confirms  that (a) it has  received and reviewed a
     copy of the Private Placement Memorandum dated August __, 1997, relating to
     the Class [A-7] [A-PO] [B-3] [B-4] [B-5] Certificates and reviewed,  to the
     extent  it  deemed   appropriate,   the  documents   attached   thereto  or
     incorporated  by reference  therein,  (b) it has had the opportunity to ask
     questions of, and receive  answers from NASCOR  concerning  the Class [A-7]
     [A-PO] [B-3] [B-4] [B-5] Certificates and all matters relating thereto, and
     obtain any additional  information  (including  documents)  relevant to its
     decision to purchase the Class [A-7] [A-PO] [B-3] [B-4] [B-5]  Certificates
     that NASCOR possesses or can possess without unreasonable effort or expense
     and (c) it has undertaken its own independent analysis of the investment in
     the Class [A-7] [A-PO] [B-3] [B-4] [B-5]  Certificates.  The Purchaser will
     not use or disclose  any  information  it receives in  connection  with its
     purchase of the Class [A-7]  [A-PO]  [B-3] [B-4] [B-5]  Certificates  other
     than in connection with a subsequent sale of Class [A-7] [A-PO] [B-3] [B-4]
     [B-5] Certificates.

          [(e)  For  the  Class  A-PO,  Class  B-3,  Class  B-4  and  Class  B-5
     Certificates:  Either (i) the Purchaser is not an employee  benefit plan or
     other retirement  arrangement subject to Title I of the Employee Retirement
     Income Security Act of 1974, as amended,  ("ERISA"), or Section 4975 of the
     Internal  Revenue Code of 1986, as amended (the "Code"),  or a governmental
     plan, as defined in Section 3(32) of ERISA subject to any federal, state or
     local law ("Similar  Law") which is, to a material  extent,  similar to the
     foregoing  provisions  of ERISA or the Code  (collectively,  a "Plan"),  an
     agent  acting on behalf of a Plan,  or a person  utilizing  the assets of a
     Plan or (ii) the  Purchaser  has  provided  (a) a  "Benefit  Plan  Opinion"
     satisfactory  to NASCOR and the  Trustee  of the Trust  Estate and (b) such
     other opinions of counsel,  officers' certificates and agreements as NASCOR
     or the Master  Servicer  may have  required.  A Benefit  Plan Opinion is an
     opinion of counsel to the effect that the proposed  transfer will not cause
     the assets of the Trust Estate to be regarded as "plan  assets" and subject
     to the prohibited transaction



<PAGE>



     provisions  of ERISA,  the Code or  Similar  Law and will not  subject  the
     Trustee, the Seller or the Master Servicer to any obligation in addition to
     those  undertaken in the Pooling and  Servicing  Agreement  (including  any
     liability for civil  penalties or excise taxes  imposed  pursuant to ERISA,
     Section 4975 of the Code or Similar Law).]

          [(e) For the Class A-7  Certificates:  If the purchaser is an employee
     benefit  plan or other  retirement  arrangement  subject  to Title I of the
     Employee  Retirement Income Security Act of 1974, as amended ("ERISA"),  or
     Section 4975 of the Internal Revenue Code of 1986, as amended (the "Code"),
     or a governmental plan, as defined in section 3(32) of ERISA subject to any
     federal, state or local law ("Similar Law") which is, to a material extent,
     similar to the foregoing  provisions of ERISA or the Code (collectively,  a
     "Plan"),  an agent  acting on behalf  of a Plan or a person  utilizing  the
     assets of a Plan,  then such  Plan or  person is an  "accredited  investor"
     within the meaning of Rule 501(a)(1) of the Act.]

          (f)  If the  Purchaser  is a  depository  institution  subject  to the
     jurisdiction of the Office of the Comptroller of the Currency ("OCC"),  the
     Board of  Governors  of the Federal  Reserve  System  ("FRB"),  the Federal
     Deposit Insurance  Corporation  ("FDIC"),  the Office of Thrift Supervision
     ("OTS") or the National Credit Union Administration ("NCUA"), the Purchaser
     has reviewed the "Supervisory  Policy  Statement on Securities  Activities"
     dated January 28, 1992 of the Federal  Financial  Institutions  Examination
     Council and the April 15, 1994 Interim  Revision  thereto as adopted by the
     OCC,  FRB,  FDIC,  OTS and NCUA  (with  modifications  as  applicable),  as
     appropriate,  other applicable  investment  authority,  rules,  supervisory
     policies and guidelines of these  agencies and, to the extent  appropriate,
     state banking  authorities and has concluded that its purchase of the Class
     [A-7] [A-PO] [B-3] [B-4] [B-5] Certificates is in compliance therewith.

     Section 3. Transfer of Class [A-7] [A-PO] [B-3] [B-4] [B-5] Certificates.

          (a) The Purchaser  understands that the Class [A-7] [A-PO] [B-3] [B-4]
     [B-5]  Certificates  have not been  registered  under the Securities Act of
     1933 (the "Act") or any state  securities  laws and that no transfer may be
     made unless the Class [A-7]  [A-PO]  [B-3]  [B-4]  [B-5]  Certificates  are
     registered  under the Act and  applicable  state law or unless an exemption
     from  registration is available.  The Purchaser  further  understands  that
     neither NASCOR, the Master Servicer nor the Trustee is under any obligation
     to register the Class [A-7] [A-PO] [B-3] [B-4] [B-5]  Certificates  or make
     an exemption available.  In the event that such a transfer is to be made in
     reliance  upon an exemption  from the Act or  applicable  state  securities
     laws, (i) the Trustee shall  require,  in order to assure  compliance  with
     such laws, that the  Certificateholder's  prospective transferee certify to
     NASCOR and the  Trustee as to the  factual  basis for the  registration  or
     qualification  exemption  relied upon,  and (ii) unless the transferee is a
     "Qualified Institutional Buyer" within the meaning of Rule 144A of the Act,
     the Trustee or NASCOR may, if such transfer is made within three years from
     the later of (a) the Closing  Date or (b) the last date on which  NASCOR or
     any  affiliate  thereof  was a holder of the  Certificates  proposed  to be
     transferred,  require an Opinion of Counsel that such  transfer may be made
     pursuant to an exemption from the



<PAGE>



     Act and state  securities  laws,  which  Opinion of Counsel shall not be an
     expense  of  the  Trustee,   the  Master  Servicer  or  NASCOR.   Any  such
     Certificateholder  desiring to effect such transfer shall,  and does hereby
     agree to,  indemnify  the Trustee,  the Master  Servicer,  any Paying Agent
     acting on behalf of the Trustee and NASCOR  against any liability  that may
     result if the transfer is not so exempt or is not made in  accordance  with
     such federal and state laws.

          (b) No transfer of a Class [A-7] [A-PO] [B-3] [B-4] [B-5]  Certificate
     shall be made unless the transferee  provides NASCOR and the Trustee with a
     Transferee's Letter, substantially in the form of this Agreement.

          (c) The Purchaser acknowledges that its Class [A-7] [A-PO] [B-3] [B-4]
     [B-5] Certificates bear a legend setting forth the applicable  restrictions
     on transfer.

     IN WITNESS WHEREOF, the undersigned has caused this Agreement to be validly
executed by its duly authorized  representative as of the day and the year first

     Trust Estate to be regarded as "plan assets" and subject to the  prohibited
     transaction  provisions  of  ERISA,  the Code or  Similar  Law and will not
     subject the Trustee, the Seller or the Master Servicer to any obligation in
     addition  to  those  undertaken  in the  Pooling  and  Servicing  Agreement
     (including  any  liability  for civil  penalties  or excise  taxes  imposed
     pursuant to ERISA, Section 4975 of the Code or Similar Law).

     IN WITNESS WHEREOF, the undersigned has caused this Agreement to be validly
executed by its duly authorized  representative as of the day and the year first

     Section 2.01 Reports and Notices

     (a) In connection  with the performance of its duties under the Pooling and
Servicing  Agreement  relating to the realization upon defaulted Mortgage Loans,
the Company as Master  Servicer  shall  provide to the  Purchaser  the following
notices and reports:

          (i)  Within  five  Business  Days  after  each  Distribution  Date (or
     included in or with the monthly statements to  Certificateholders  pursuant
     to the Pooling and Servicing Agreement),  the Company, shall provide to the
     Purchaser a report,  using the same  methodology  and  calculations  in its
     standard servicing  reports,  indicating for the Trust Estate the number of
     Mortgage Loans that are (A) thirty days, (B) sixty days, (C) ninety days or
     more  delinquent  or (D) in  foreclosure,  and  indicating  for  each  such
     Mortgage Loan the loan number and outstanding principal balance.

          (ii) Prior to the  Commencement  of Foreclosure in connection with any
     Mortgage Loan,  the Company shall cause,  to the extent that the Company as
     Master  Servicer  is  granted  such  authority  in  the  related  Servicing
     Agreement,  the related  Servicer to provide  the  Purchaser  with a notice
     (sent by telecopier) of such proposed and imminent foreclosure, stating the
     loan number and the aggregate  amount owing under the Mortgage  Loan.  Such
     notice may be provided to the Purchaser in the form of a copy of a referral
     letter from such  Servicer to an attorney  requesting  the  institution  of
     foreclosure.

     (b) If requested by the Purchaser,  the Company shall cause,  to the extent
that the Company as Master  Servicer is granted  such  authority  in the related
Servicing Agreement, the



<PAGE>



related Servicer to make its servicing  personnel available (during their normal
business  hours) to respond to reasonable  inquiries,  by phone or in writing by
facsimile,  electronic,  or overnight  mail  transmission,  by the  Purchaser in
connection  with any Mortgage Loan  identified in a report under  subsection (a)
(i) (B),  (a) (i) (C),  (a) (i) (D),  or (a) (ii)  which  has been  given to the
Purchaser;  provided,  that (1) the related  Servicer  shall only be required to
provide information that is readily accessible to its servicing personnel and is
non-confidential and (2) the related Servicer shall respond within five Business
Days orally or in writing by facsimile transmission.

     (c) In addition to the  foregoing,  the Company shall cause,  to the extent
that the Company as Master  Servicer is granted  such  authority  in the related
Servicing  Agreement,  the  related  Servicer to provide to the  Purchaser  such
information as the Purchaser may reasonably request provided, however, that such
information  is consistent  with normal  reporting  practices,  concerning  each
Mortgage  Loan that is at least ninety days  delinquent  and each  Mortgage Loan
which has become  real estate  owned,  through  the final  liquidation  thereof;
provided,   that  the  related  Servicer  shall  only  be  required  to  provide
information  that  is  readily  accessible  to its  servicing  personnel  and is
non-confidential  provided,  however,  that the  Purchaser  will  reimburse  the
Company and the related Servicer for any out of pocket expenses.

     Section 2.02 Purchaser's Election to Delay Foreclosure Proceedings

     (a) The  Purchaser  shall be deemed to direct the  Company to cause (to the
extent that the  Company as Master  Servicer is granted  such  authority  in the
related  Servicing  Agreement)  the related  Servicer that in the event that the
Company does not receive written notice of the Purchaser's  election pursuant to
subsection (b) below within 24 hours (exclusive of any intervening  non-Business
Days) of  transmission  of the notice provided by the Company under Section 2.01
(a) (ii)  subject to  extension  as set forth in Section  2.02(b),  the  related
Servicer may proceed with the  Commencement  of  Foreclosure  in respect of such
Mortgage Loan in accordance with its normal foreclosure policies without further
notice  to the  Purchaser.  Any  foreclosure  that  has  been  initiated  may be
discontinued  (i) without  notice to the Purchaser if the Mortgage Loan has been
brought  current or if a refinancing  or  prepayment  occurs with respect to the
Mortgage  Loan  (including  by means of a short  payoff  approved by the related
Servicer) or (ii) if the related Servicer has reached the terms of a forbearance
agreement  with the  borrower.  In such latter  case,  the related  Servicer may
complete such forbearance agreement unless instructed otherwise by the Purchaser
within two Business Days notification.

     (b) In  connection  with any  Mortgage  Loan with respect to which a notice
under Section  2.01(a)(ii)  has been given to the  Purchaser,  the Purchaser may
elect to instruct the Company to cause, to the extent that the Company as Master
Servicer is granted  such  authority  in the related  Servicing  Agreement,  the
related Servicer to delay the Commencement of Foreclosure until such time as the
Purchaser determines that the related Servicer may proceed with the Commencement
of  Foreclosure.  Such  election  must be evidenced by written  notice  received
within 24 hours (exclusive of any intervening non-Business Days) of transmission
of the notice  provided by the Company under Section  2.01(a)(ii).  Such 24 hour
period shall be extended for no longer than an  additional  four  Business  Days
after the  receipt  of the  information  if the  Purchaser  requests  additional
information related to such foreclosure;  provided,  however, that the Purchaser
will have at least one  Business  Day to  respond  to any  requested  additional
information. Any such


additional  information  shall  (i) be  provided  only to the  extent  it is not
confidential  in nature and (ii) be  obtainable  by the  related  Servicer  from
existing reports,  certificates or statements or otherwise be readily accessible
to its servicing  personnel.  The Purchaser  agrees that it has no right to deal
with the mortgagor  during such period.  However,  if such servicing  activities
include  acceptance  of a  deed-in-lieu  of  foreclosure  or short  payoff,  the
Purchaser will be notified and given two Business Days to respond.

     (c) With respect to any Mortgage Loan as to which the Purchaser has made an
Election to Delay Foreclosure, the Purchaser shall obtain a Current Appraisal as
soon as practicable,  but in no event more than 15 business days thereafter, and
shall provide the Company with a copy of such Current Appraisal.

     (d) Within two Business  Days of making any Election to Delay  Foreclosure,
the Purchaser  shall remit by wire  transfer to the Company,  for deposit in the
Collateral  Fund, an amount,  as calculated by the Company,  equal to the sum of
(i) 125% of the greater of the unpaid principal balance of the Mortgage Loan and
the value shown in the Current  Appraisal  referred to in  subsection  (c) above
(or, if such Current Appraisal has not yet been obtained, the Company's estimate
thereof,  in which case the  required  deposit  under this  subsection  shall be
adjusted upon obtaining such Current Appraisal), and (ii) three months' interest
on the Mortgage Loan at the applicable  Mortgage  Interest Rate. If any Election
to Delay Foreclosure extends for a period in excess of three months (such excess
period  being  referred to herein as the "Excess  Period"),  within two Business
Days the  Purchaser  shall remit by wire  transfer in advance to the Company for
deposit in the Collateral Fund the amount of each additional  month's  interest,
as  calculated  by the Company,  equal to interest on the  Mortgage  Loan at the
applicable  Mortgage  Interest  Rate for the  Excess  Period.  The terms of this
Agreement  will no longer apply to the  servicing of any Mortgage  Loan upon the
failure of the  Purchaser  to deposit any of the above  amounts  relating to the
Mortgage Loan within two Business Days of the Election to Delay  Foreclosure  or
within two Business Days of the  commencement  of the Excess  Period  subject to
Section 3.01.

     (e) With respect to any Mortgage Loan as to which the Purchaser has made an
Election to Delay Foreclosure, the Company may withdraw from the Collateral Fund
from time to time amounts  necessary to reimburse  the related  Servicer for all
related  Monthly  Advances  and  Liquidation  Expenses  thereafter  made by such
Servicer in accordance with the Pooling and Servicing  Agreement and the related
Servicing  Agreement.  To the  extent  that the  amount of any such  Liquidation
Expenses is determined by the Company based on estimated  costs,  and the actual
costs are  subsequently  determined  to be higher,  the Company may withdraw the
additional  amount from the Collateral Fund. In the event that the Mortgage Loan
is brought current by the mortgagor and the foreclosure  action is discontinued,
the amounts so withdrawn from the Collateral  Fund shall be redeposited  therein
and to the extent that reimbursement therefor from amounts paid by the mortgagor
is not prohibited pursuant to the Pooling and Servicing Agreement or the related
Servicing  Agreement  as of the  date  hereof,  applicable  law  or the  related
mortgage note. Except as provided in the preceding  sentence,  amounts withdrawn
from the  Collateral  Fund to cover Monthly  Advances and  Liquidation  Expenses
shall not be redeposited  therein or otherwise  reimbursed to the Purchaser.  If
and when any such Mortgage Loan is brought current by the mortgagor, all amounts
remaining in the Collateral Fund in respect of such Mortgage Loan



<PAGE>



(after  adjustment for all permitted  withdrawals and deposits  pursuant to this
subsection) shall be released to the Purchaser.

     (f) With respect to any Mortgage Loan as to which the Purchaser has made an
Election to Delay  Foreclosure,  the related  Servicer shall continue to service
the Mortgage Loan in accordance  with its customary  procedures  (other than the
delay in  Commencement  of  Foreclosure  as  provided  herein).  If and when the
Purchaser shall notify the Company that it believes that it is appropriate to do
so, the related  Servicer may proceed with the  Commencement of Foreclosure.  In
any event,  if the Mortgage Loan is not brought  current by the mortgagor by the
time the loan becomes 6 months  delinquent,  the  Purchaser's  election shall no
longer be effective  and at the  Purchaser's  option,  either (I) the  Purchaser
shall  purchase  the Mortgage  Loan from the related  Trust Estate at a purchase
price equal to the fair market  value as shown on the Current  Appraisal,  to be
paid by (x) applying any balance in the Collateral Fund to such to such purchase
price, and (y) to the extent of any deficiency,  by wire transfer if immediately
available  funds from the  Purchaser  to the  Company for deposit in the related
Certificate Account or Lower-Tier Certificate Account as applicable; or (ii) the
related Servicer may proceed with the Commencement of Foreclosure.

     (g) Upon the occurrence of a liquidation  with respect to any Mortgage Loan
as to which the Purchaser made an Election to Delay  Foreclosure and as to which
the  related  Servicer   proceeded  with  the  Commencement  of  Foreclosure  in
accordance with subsection (f) above, the Company shall calculate the amount, if
any, by which the value shown on the Current Appraisal obtained under subsection
(c) exceeds the actual sales price obtained for the related  Mortgaged  Property
(net of  Liquidation  Expenses  and  accrued  interest  related to the  extended
foreclosure  period),  and the Company shall  withdraw the amount of such excess
from the  Collateral  Fund,  shall remit the same to the Trust Estate and in its
capacity as Master  Servicer  shall apply such amount as additional  Liquidation
Proceeds  pursuant to the Pooling and  Servicing  Agreement.  After  making such
withdrawal,  all amounts  remaining  in the  Collateral  Fund in respect of such
Mortgage  Loan (after  adjustment  for all  permitted  withdrawals  and deposits
pursuant to this Agreement) shall be released to the Purchaser.

     Section 2.03 Purchaser's Election to Commence Foreclosure Proceedings

     (a) In  connection  with any  Mortgage  Loan  identified  in a report under
Section 2.01(a)(i)(B), the Purchaser may elect to instruct the Company to cause,
to the extent that the Company as Master  Servicer is granted such  authority in
the  related  Servicing  Agreement,  the related  Servicer  to proceed  with the
Commencement  of  Foreclosure  as soon as  practicable.  Such  election  must be
evidenced by written notice  received by the Company by 5:00 p.m., New York City
time,  on the third  Business  Day  following  the delivery of such report under
Section 2.01(a)(i).

     (b) Within two  Business  Days of making any  Election  to  Foreclose,  the
Purchaser  shall remit to the Company,  for deposit in the  Collateral  Fund, an
amount,  as  calculated  by the  Company,  equal to 125% of the  current  unpaid
principal balance of the Mortgage Loan and three months interest on the Mortgage
Loan at the  applicable  Mortgage  Interest  Rate. If and when any such Mortgage
Loan is brought current by the mortgagor, all amounts in the Collateral Fund in



<PAGE>



respect of such Mortgage Loan (after  adjustment  for all permitted  withdrawals
and deposits  pursuant to this Agreement) shall be released to the Purchaser and
to the extent that reimbursement  therefor from amounts paid by the mortgagor is
not  prohibited  pursuant to the Pooling and Servicing  Agreement or the related
Servicing  Agreement  as of the  date  hereof,  applicable  law  or the  related
mortgage note. The terms of this Agreement will no longer apply to the servicing
of any  Mortgage  Loan upon the  failure of the  Purchaser  to deposit the above
amounts  relating to the Mortgage  Loan within two Business Days of the Election
to Foreclose subject to Section 3.01.

     (c) With respect to any Mortgage Loan as to which the Purchaser has made an
Election  to  Foreclose,  the  related  Servicer  shall  continue to service the
Mortgage  Loan  in  accordance  with  its  customary   procedures   (other  than
Commencement of Foreclosure as provided herein).  In connection  therewith,  the
Company shall have the same rights to make  withdrawals for Monthly Advances and
Liquidation  Expenses  from the  Collateral  Fund as are provided  under Section
2.02(e), and the Company shall make reimbursements thereto to the limited extent
provided under such subsection in accordance with its customary procedures.  The
Company shall not be required to cause, to the extent that the Company as Master
Servicer is granted  such  authority  in the related  Servicing  Agreement,  the
related Servicer to proceed with the Commencement of Foreclosure if (i) the same
is stayed as a result of the  mortgagor's  bankruptcy or is otherwise  barred by
applicable  law, or to the extent that all legal  conditions  precedent  thereto
have not yet been complied with, or (ii) the Company  believes there is a breach
of representations or warranties by the Company, a Servicer,  or a Seller, which
may result in a repurchase or  substitution  of such Mortgage Loan, or (iii) the
Company or related Servicer  reasonably  believes the Mortgaged  Property may be
contaminated with or affected by hazardous wastes or hazardous  substances (and,
without  limiting  the  related   Servicer's  right  not  to  proceed  with  the
Commencement of Foreclosure, the Company supplies the Purchaser with information
supporting  such  belief).  Any  foreclosure  that  has  been  initiated  may be
discontinued  (x) without  notice to the Purchaser if the Mortgage Loan has been
brought  current or if a refinancing  or  prepayment  occurs with respect to the
Mortgage Loan  (including by means of a short payoff  approved by the Purchaser)
or (y) with  notice to the  Purchaser  if the related  Servicer  has reached the
terms of a forbearance  agreement unless  instructed  otherwise by the Purchaser
within two Business Days of such  notification.  Any such  instruction  shall be
based upon a decision that such forbearance  agreement is not in conformity with
reasonable servicing practices.

     (d) Upon the occurrence of a liquidation  with respect to any Mortgage Loan
as to which the  Purchaser  made an  Election to  Foreclose  and as to which the
related  Servicer  proceeded with the  Commencement of Foreclosure in accordance
with subsection (c) above,  the Company shall  calculate the amount,  if any, by
which  the  unpaid  principal  balance  of the  Mortgage  Loan  at the  time  of
liquidation  (plus  all  unreimbursed   interest  and  servicing   advances  and
Liquidation  Expenses  in  connection  therewith  other than those paid from the
Collateral  Fund)  exceeds  the actual  sales  price  obtained  for the  related
Mortgaged  Property,  and the Company  shall  withdraw the amount of such excess
from the  Collateral  Fund,  shall remit the same to the Trust Estate and in its
capacity as Master  Servicer  shall apply such amount as additional  Liquidation
Proceeds  pursuant to the Pooling and  Servicing  Agreement.  After  making such
withdrawal,  all amounts  remaining in the Collateral Fund (after adjustment for
all  withdrawals  and  deposits  pursuant to  subsection  (c) in respect of such
Mortgage Loan shall be released to the Purchaser.

     (a) With respect to all Mortgage  Loans  included in the Trust Estate,  the
Purchaser's  right to make any Election to Delay  Foreclosure or any Election to
Foreclose and the Company's  obligations  under Section 2.01 shall terminate (i)
at such  time as the  Principal  Balance  of the Class B  Certificates  has been
reduced  to  zero,  (ii) if the  greater  of (x) 43% (or such  lower  or  higher
percentage  that  represents  the  related  Servicer's  actual  historical  loss
experience  with respect to the Mortgage Loans in the related pool as determined
by the Company) of the aggregate  principal  balance of all Mortgage  Loans that
are in  foreclosure or are more than 90 days  delinquent on a contractual  basis
and REO  properties  or (y) the  aggregate  amount  that the  Company  estimates
through the normal servicing  practices of the related Servicer will be required
to be withdrawn  from the  Collateral  Fund with respect to Mortgage Loans as to
which the Purchaser has made an Election to Delay  Foreclosure or an Election to
Foreclosure,  exceeds  (z) the  then-current  principal  balance  of the Class B
Certificates,  (iii) upon any transfer by the  Purchaser of any interest  (other
than the minority interest therein,  but only if the transferee provides written
acknowledgment  to the Company of the Purchaser's  right hereunder and that such
transferee will have no rights  hereunder) in the Class B Certificates  (whether
or not such transfer is registered  under the Pooling and Servicing  Agreement),
including any such transfer in connection with a termination of the Trust Estate
or (iv) any breach of the terms of this Agreement by the Purchaser.

     (b)  Except as set forth in  2.04(a),  this  Agreement  and the  respective
rights,  obligations  and  responsibilities  of the  Purchaser  and the  Company
hereunder shall  terminate upon the later to occur of (i) the final  liquidation
of the last Mortgage  Loan as to which the Purchaser  made any Election to Delay
Foreclosure  or any Election to Foreclose  and the  withdrawal  of all remaining
amounts in the  Collateral  Fund as provided  herein and (ii) ten Business Days'
notice.  The Purchaser's  right to make an election  pursuant to Section 2.02 or
Section 2.03 hereof with respect to a particular  Mortgage Loan shall  terminate

or 2.03(b) or if the Purchaser fails to make any other deposit to the Collateral
Fund pursuant to this Agreement.

benefit of the  Certificateholders,  until  withdrawn from the  Collateral  Fund
pursuant  to  Section  2.02 or 2.03  hereof.  The  Collateral  Fund  shall be an
"outside reserve fund" within the meaning of the REMIC Provisions,  beneficially
owned by the  Purchaser  for federal  income tax  purposes.  All  income,  gain,
deduction  or loss with  respect  to the  Collateral  Fund  shall be that of the
Purchaser. All distributions from the Trust Fund to the Collateral Fund shall be
treated as distributed to the Purchaser as the beneficial owner thereof.

     Upon the  termination of this Agreement and the liquidation of all Mortgage
Loans as to which the  Purchaser has made any Election to Delay  Foreclosure  or
any Election to Foreclose  pursuant to Section  2.04 hereof,  the Company  shall
distribute to the Purchaser all amounts  remaining in the Collateral Fund (after
adjustment  for  all  deposits  and  permitted   withdrawals  pursuant  to  this
Agreement)  together  with any  investment  earnings  thereon.  In the event the
Purchaser  has made  any  Election  to  Delay  Foreclosure  or any  Election  to
Foreclose,  prior to any distribution to the Purchaser of all amounts  remaining
in the Collateral Fund, funds in the Collateral Fund shall be applied consistent
with the terms of this Agreement.

     Section 3.02. Collateral Fund Permitted Investments.

     The Company shall,  at the written  direction of the Purchaser,  invest the
funds in the  Collateral  Fund in Collateral  Fund Permitted  Investments.  Such
direction shall not be changed more frequently than quarterly. In the absence of
any direction,  the Company shall select such investments in accordance with the
definition of Collateral Fund Permitted Investments in its discretion.

     All income and gain  realized  from any  investment as well as any interest
earned  on  deposits  in  the  Collateral  Fund  (net  of  any  losses  on  such
investments)  and any  payments of principal  made in respect of any  Collateral
Fund  Permitted  Investment  shall be  deposited  in the  Collateral  Fund  upon
receipt.  All costs and realized losses associated with the purchase and sale of
Collateral  Fund Permitted  Investments  shall be borne by the Purchaser and the
amount  of net  realized  losses  shall be  deposited  by the  Purchaser  in the
Collateral Fund promptly upon realization.  The Company shall  periodically (but
not more  frequently  than monthly)  distribute to the Purchaser upon request an
amount of cash,  to the extent cash is  available  therefore  in the  Collateral
Fund,  equal to the amount by which the balance of the  Collateral  Fund,  after
giving effect to all other  distributions to be made from the Collateral Fund on
such  date,  exceeds  the  Required  Collateral  Fund  Balance.  Any  amounts so
distributed  shall be  released  from the lien  and  security  interest  of this
Agreement.

     Section 3.03. Grant of Security Interest

     The  Purchaser  hereby  grants  to  the  Company  for  the  benefit  of the
Certificateholders under the Pooling and Servicing Agreement a security interest
in and lien on all of the  Purchaser's  right,  title and interest,  whether now
owned or hereafter acquired, in and to: (1) the Collateral Fund, (2) all amounts
deposited in the Collateral  Fund and Collateral  Fund Permitted  Investments in
which such  amounts are  invested  (and the  distributions  and proceeds of such
investments)  and (3) all cash and  non-cash  proceeds of any of the  foregoing,
including  proceeds of the  voluntary  conversion  thereof (all of the foregoing
collectively, the "Collateral").



<PAGE>



     The  Purchaser  acknowledges  the  lien  on the  security  interest  in the
Collateral for the benefit of the  Certificateholders.  The Purchaser shall take
all actions  requested by the Company as may be reasonably  necessary to perfect
the security  interest  created under this Agreement in the Collateral and cause
it to be  prior  to all  other  security  interests  and  liens,  including  the
execution  and  delivery  to the  Company  for filing of  appropriate  financing
statements in accordance with applicable law. The Company shall file appropriate
continuation  statements,  or  appoint  an  agent  on its  behalf  to file  such
statements, in accordance with applicable law.

     Section 3.04. Collateral Shortfalls.

     In the event that amounts on deposit in the Collateral Fund at any time are
insufficient  to  cover  any  withdrawals  therefrom  that the  Company  is then
entitled to make hereunder, the Purchaser shall be obligated to pay such amounts
to the Company  immediately  upon demand.  Such  obligation  shall  constitute a
general corporate  obligation of the Purchaser.  The failure to pay such amounts
within two Business Days of such demand (except for amounts to cover interest on
a Mortgage  Loan  pursuant  to Sections  2.02(d)  and 2.03 (b)),  shall cause an
immediate  termination  of the  Purchaser's  right to make any Election to Delay
Foreclosure  or Election to Foreclose and the Company's  obligations  under this
Agreement  with  respect to all  Mortgage  Loans to which  such  insufficiencies
relate, without the necessity of any further notice or demand on the part of the
Company.
